    THIS SUMMARY HIGHLIGHTS SELECTED INFORMATION CONTAINED ELSEWHERE IN THIS
PROSPECTUS. THIS SUMMARY MAY NOT CONTAIN ALL OF THE INFORMATION THAT YOU SHOULD
CONSIDER BEFORE INVESTING IN OUR COMMON STOCK. YOU SHOULD READ THE ENTIRE
PROSPECTUS CAREFULLY, INCLUDING "RISK FACTORS" AND THE FINANCIAL STATEMENTS AND

                                   LIVEPERSON


    LivePerson is a provider of technology that facilitates real-time sales and
customer service for companies doing business on the Internet. We are an
application service provider and we offer our proprietary real-time interaction
technology as an outsourced service. Our service appears as a LivePerson-branded
or custom-created icon on our clients' Web sites. When an Internet user clicks
on the icon, a pop-up dialogue window appears, enabling our clients to
communicate directly with Internet users via text-based chat. Our clients can
respond to Internet user inquiries in real time, and can thereby enhance their
online shopping experiences. Our technology requires no software or hardware
installation by our clients or their Internet users.



    Based on feedback received from our clients, we believe that our service
offers our clients the opportunity to increase sales, reduce customer service
costs and increase responsiveness to Internet user needs and preferences.
Because we are an application service provider and provide our clients with a
service rather than an in-house technology solution, our clients can devote
their information technology resources to other priorities. We offer low
start-up costs, currently $1,000 per client, and reasonable ongoing monthly
fees, currently $250 per operator access account, or seat. We can implement our
LivePerson service immediately following a two-hour training session. Upgrades
to the LivePerson service are automatic because they are installed on our
servers, without requiring action by either our clients or Internet users. We
also offer our clients the ability to add capacity whenever requested.



    We currently have more than 450 clients. Our service benefits companies of
all sizes doing business on the Internet, including online retailers, online
service providers and traditional offline businesses with a Web presence. Our
largest clients in the first two months of 2000 were GMAC's ditech.com,
Homelender.com, MyHome.com, National Discount Brokers, Neiman Marcus, ShopNow,
TradeCapture.com and WhatsHotNow.



    Prospective investors should be aware that investing in our common stock
involves many risks, which are described more fully in the section "Risk
Factors" beginning on page 7. In particular, we face risks including, but not
limited to, the facts that:



    -  we have an unproven business model and will rely on revenue from the
       LivePerson service for substantially all of our revenue for the
       forseeable future;



    -  we have a limited operating history related to the LivePerson service and
       a history of significant losses, including a net loss of $9.8 million in
       1999;



    -  we have an accumulated deficit of approximately $9.8 million as of
       December 31, 1999;



    -  we anticipate incurring losses in the foreseeable future which may be
       substantial; and



    -  we operate in an emerging and highly competitive marketplace with
       relatively low barriers to entry.



    We plan to enhance our current position as a provider of real-time sales and
customer service technology for companies doing business on the Internet. The
key elements of our strategy include:


    -  strengthening our market position by significantly expanding our
       installed client base;

                                       3
<PAGE>
    -  adding features and functionality to our live interaction platform to
       increase the value of our service to our clients and their reliance on
       its benefits;

    -  continuing to build brand awareness;

    -  continuing to develop our technological capabilities by devoting
       significant resources to network architecture and software design;

    -  seeking opportunities to form strategic alliances and make acquisitions
       where appropriate; and

    -  expanding our international presence.


    Prospective investors should also be aware of the risks related to achieving
these strategic objectives which are described more fully in "Risk Factors."



    Our business was incorporated in the State of Delaware in November 1995
under the name Sybarite Interactive Inc. Prior to November 1998, we generated
programming revenue from services primarily related to Web-based community
programming and media design. In 1998, we shifted our core business focus to the
development of the LivePerson service and phased out our programming and media
design business, which last generated revenue in December 1999 and is not
expected to generate any future revenue. Following our introduction of the
LivePerson service in November 1998, we changed our name in January 1999 to Live
Person, Inc., and on March 8, 2000 to LivePerson, Inc. Our principal executive
offices are located at 462 Seventh Avenue, 10th Floor, New York, New York
10018-7606. Our telephone number is (212) 277-8950. The address of our Web site
is www.liveperson.com. Information contained on our Web site does not constitute
part of this prospectus.

                                  RISK FACTORS

    AN INVESTMENT IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD
CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW, TOGETHER WITH THE OTHER
INFORMATION CONTAINED IN THIS PROSPECTUS, BEFORE MAKING AN INVESTMENT DECISION.
AS A RESULT OF THE FOLLOWING RISKS, THE MARKET PRICE OF OUR COMMON STOCK COULD
DECLINE, AND YOU COULD LOSE ALL OR PART OF YOUR INVESTMENT.

                         RISKS RELATED TO OUR BUSINESS

WE HAVE A LIMITED OPERATING HISTORY PROVIDING THE LIVEPERSON SERVICE AND EXPECT
    TO ENCOUNTER DIFFICULTIES FACED BY EARLY STAGE COMPANIES IN NEW AND RAPIDLY
    EVOLVING MARKETS.

    We have only a limited operating history providing the LivePerson service
upon which to base an evaluation of our current business and future prospects.
We began offering the LivePerson service in November 1998; accordingly, the
revenue and income potential of our business and the related market are
unproven. As a result of our limited operating history as a provider of
real-time sales and customer service technology for companies doing business on
the Internet, we have only one year of historical financial data relating to the
LivePerson service upon which to forecast revenue and results of operations.

    In addition, because this market is relatively new and rapidly evolving, we
have limited insight into trends that may emerge and affect our business. Before
investing in us, you should evaluate the risks, expenses and problems frequently
encountered by companies such as ours that are in the early stages of
development and that are entering new and rapidly changing markets. These risks
include our ability to:

    -  attract more clients and retain existing clients;


    -  sell additional seats, which generate monthly fees, and other services to
       our existing clients;


    -  effectively market and maintain our brand name;

    -  respond effectively to competitive pressures;

    -  continue to develop and upgrade our technology; and

    -  attract, integrate, retain and motivate qualified personnel.

    If we are unsuccessful in addressing some or all of these risks, our
business, financial condition and results of operations would be materially and
adversely affected.


OUR ANNUAL REVENUE HAS NEVER EXCEEDED $640,000, WE HAD AN ACCUMULATED DEFICIT OF
    $9.8 MILLION AS OF DECEMBER 31, 1999 AND WE EXPECT TO INCUR SIGNIFICANT
    LOSSES FOR THE FORESEEABLE FUTURE.



    We have not achieved profitability and, as we expect to continue to incur
significant operating expenses and to make significant capital expenditures, we
expect to continue to experience significant losses and negative cash flow for
the foreseeable future. We recorded a net loss of $20,000 for the year ended
December 31, 1998 (the year in which we commenced offering the LivePerson
service) and a net loss of approximately $9.8 million for the year ended
December 31, 1999. As of December 31, 1999, our accumulated deficit was
approximately $9.8 million. Even if we do achieve profitability, we cannot
assure you that we can sustain or increase profitability on a quarterly or
annual basis in the future. Failure to achieve or maintain profitability may
materially and adversely affect the market price of our common stock.


WE HAVE AN UNPROVEN BUSINESS MODEL AND MAY NOT GENERATE SUFFICIENT REVENUE FOR
    OUR BUSINESS TO SURVIVE.


    Our business model is based on the delivery of real-time sales and customer
service technology to companies doing business on the Internet, a largely
untested business. Sales and


                                       7
<PAGE>

customer service historically have been provided primarily in person or by
telephone. Our business model assumes that companies doing business on the
Internet will choose to provide sales and customer service via the Internet. Our
business model also assumes that many companies will recognize the benefits of
an outsourced application, that Internet users will choose to engage a customer
service representative in a live text-based interaction, that this interaction
will maximize sales opportunities and enhance the online shopping experience and
that companies will seek to have their online sales and customer service
technology provided by us. If any of these assumptions is incorrect, our
business may be harmed.



WE EXPECT THAT ALL OF OUR REVENUE WILL COME FROM THE LIVEPERSON SERVICE FOR THE
    FORESEEABLE FUTURE AND IF WE ARE NOT SUCCESSFUL IN SELLING THE SERVICE, OUR
    REVENUE WILL NOT INCREASE AND MAY DECLINE.



    The success of our business currently depends, and for the foreseeable
future will continue to substantially depend, on the sale of only one service.
Revenue related to the LivePerson service, which will account for all of our
revenue for the forseeable future, is comprised of initial non-refundable set-up
fees and ongoing monthly fees. Ongoing monthly fees, in turn, result from the
sale of seats to new clients and the sale of additional seats to existing
clients. In 1999, revenue from monthly fees has accounted for more than 90% of
LivePerson service revenue. We introduced our LivePerson service in
November 1998, and we currently have more than 450 clients. We cannot be certain
that there will be client demand for our service or that we will be successful
in penetrating the market for real-time sales and customer service technology. A
decline in the price of, or fluctuation in the demand for, the LivePerson
service, is likely to cause our revenue to decline. In addition, if our clients
were to reduce the number of seats used or fail to purchase additional seats,
our revenue might not increase.


THE SUCCESS OF OUR BUSINESS REQUIRES THAT CLIENTS CONTINUE TO USE THE LIVEPERSON
    SERVICE AND PURCHASE ADDITIONAL SEATS.


    Our LivePerson service agreements typically have no termination date and are
terminable upon 30 to 90 days' notice without penalty. If a significant number
of our clients, or any one client with a significant number of seats, were to
terminate these service agreements, reduce the number of seats purchased or fail
to purchase additional seats, our results of operations may be negatively and
materially affected. We cannot assure you that we will experience high client
retention rates. Our client retention rates may decline as a result of a number
of factors, including competition, consolidation in the Internet industry or
termination of operations by a significant number of our clients.
Dissatisfaction with the nature or quality of our services could also lead
clients to terminate our service. We depend on monthly fees from the LivePerson
service for substantially all our revenue. If our retention rate declines, our
revenue could decline unless we are able to obtain additional clients or
alternate revenue sources. Further, because of the historically small number of
seats sold in initial orders, we depend on sales to new clients and sales of
additional seats to our existing clients.


OUR QUARTERLY REVENUE AND OPERATING RESULTS ARE SUBJECT TO SIGNIFICANT
    FLUCTUATIONS WHICH MAY ADVERSELY AFFECT THE TRADING PRICE OF OUR COMMON
    STOCK.


    We expect our quarterly revenue and operating results to fluctuate
significantly in the future due to a variety of factors, including the following
factors which are in part within our control, and in part outside of our
control:



    -  market acceptance by companies doing business on the Internet of
       real-time sales and customer service technology;



    -  our clients' business success;



    -  our clients' demand for seats;



    -  our ability to attract and retain clients;


                                       8
<PAGE>

    -  the amount and timing of capital expenditures and other costs relating to
       the expansion of our operations, including those related to acquisitions;



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



    -  changes in our pricing policies or the pricing policies of our
       competitors.



Our revenue and results may also fluctuate significantly in the future due to
the following factors that are entirely outside of our control:



    -  seasonal factors affecting our clients' businesses;



    -  economic conditions specific to the Internet, electronic commerce and
       online media; and



    -  general economic conditions.


    Many of our clients' businesses are seasonal. Our clients' demand for
real-time sales and customer service technology in general and their demand for
seats, in particular, may be seasonal as well. As a result, our future revenue
and profits may vary from quarter to quarter.

    We do not believe that period-to-period comparisons of our operating results
are meaningful. You should not rely upon these comparisons as indicators of our
future performance.

    Due to the foregoing factors, it is possible that our results of operations
in one or more future quarters may fall below the expectations of securities
analysts and investors. If this occurs, the trading price of our common stock
would decline.

COMPETITION FOR PERSONNEL IN OUR INDUSTRY IS INTENSE.

    We may be unable to retain our key employees or attract, integrate or retain
other highly qualified employees in the future. We have experienced, and expect
to continue to experience, difficulty in hiring highly-skilled employees with
appropriate qualifications. As we continue to increase our client base and
expand our operations, we expect that we will hire additional technical
personnel, client services personnel and sales and marketing personnel. There is
significant competition for qualified employees in our industry, particularly
employees with technical backgrounds. If we do not succeed in attracting new
personnel or retaining and motivating our current personnel, or if we are unable
to outsource certain functions, our business, results of operations and
financial condition will be materially and adversely affected.

WE MAY NOT BE ABLE TO EFFECTIVELY MANAGE OUR EXPANDING OPERATIONS.

    Since the launch of the LivePerson service in November 1998, we have grown
rapidly. This growth has placed a significant strain on our managerial,
operational, technical and financial resources. In 2000, we intend to replace
our existing accounting and other back-office systems at a cost of approximately
$1.0 million. The new systems will have to be integrated with our operations,
controls and procedures. If we are not able to successfully integrate these new
systems with our existing systems, or if we incur significant costs in order to
achieve such integration, our business could be harmed. In order to manage our
growth, we must also continue to implement new or upgraded operating and
financial systems, procedures and controls. Our failure to expand our operations
in an efficient manner could cause our expenses to grow, our revenue to decline
or grow more slowly than expected and could otherwise have a material adverse
effect on our business, results of operations and financial condition.


    Further, as a result of our growth, the number of our employees grew from
six at December 31, 1998 to 125 at March 8, 2000. In the area of technology, we
grew from one employee at December 31, 1998, to 19 employees at December 31,
1999 and to 46 employees at March 8, 2000. We expect to nearly double our
existing technology personnel in the remainder of the year; however we cannot
assure you that we will grow by this amount. We also cannot assure you that we
will be successful in integrating these new employees or that such integration
will not distract valuable management resources.


                                       9
<PAGE>
    In addition, in January 2000, we hired our Chief Operating Officer, Dean
Margolis, and our Chief Technology Officer, James L. Reagan, who do not have
significant experience working with us or with each other. The process of
integrating new members of our senior management team can be time-consuming and
may distract other members of management from the operation of our business. If
members of our senior management are unable to work together successfully or
manage our growth, our business will be harmed.

OUR REPUTATION DEPENDS, IN PART, ON FACTORS WHICH ARE ENTIRELY OUTSIDE OF OUR
    CONTROL.


    Our service appears as a LivePerson-branded or custom-created icon on our
clients' Web sites. When an Internet user clicks on the icon, a pop-up dialogue
window appears, which, in nearly all cases, displays the slogan "Powered by
LivePerson." The customer service operators who respond to the inquiries of our
clients' Internet users are employees or agents of our clients; they are not
employees of LivePerson. As a result, we have no way of controlling the actions
of these operators. In addition, an Internet user may not know that the operator
is an employee or agent of our client, rather than a LivePerson employee. If an
Internet user were to have a negative experience in a LivePerson-powered
real-time dialogue, it is possible that this experience could be attributed to
us, which could diminish our brand and harm our business. Finally, we believe
the success of our service depends on the prominent placement of the icon on the
client's Web site, over which we also have no control.


WE MAY BE UNABLE TO CONTINUE TO BUILD AWARENESS OF THE LIVEPERSON BRAND NAME.


    Building recognition of our brand is critical to establishing the advantage
of being among the first application service providers to provide real-time
sales and customer service and to attracting new clients. If we fail to
successfully promote and maintain our brand or incur significant expenses in
promoting our brand without an associated increase in our revenue, our business,
results of operations and financial condition may be materially and adversely
affected.


WE ARE DEPENDENT ON TECHNOLOGY SYSTEMS THAT ARE BEYOND OUR CONTROL.


    The success of the LivePerson service depends in part on our clients' online
services as well as the Internet connections of visitors to their Web sites,
both of which are outside of our control. As a result, it may be difficult to
identify the source of problems if they occur. In the past, we have experienced
problems related to connectivity which have resulted in slower than normal
response times to Internet user chat requests and messages and interruptions in
service. The LivePerson service relies both on the Internet and on our
connectivity vendors for data transmission. Therefore, even when connectivity
problems are not caused by the LivePerson service, our clients or Internet users
may attribute the problem to us. This could diminish our brand and harm our
business, divert the attention of our technical personnel from our product
development efforts or cause significant client relations problems.


    In addition, we rely on two Web hosting services for Internet connectivity
to deliver our service, power, security and technical assistance. They have, in
the past, experienced problems that have resulted in slower than normal response
times and interruptions in service. If we are unable to continue utilizing the
services of our existing Web hosting providers or if our Web hosting services
experience interruptions or delays, it is possible that our business could be
harmed.

    Our service also depends on many third parties for hardware and software,
which products could contain defects. Problems arising from our use of such
hardware or software could require us to incur significant costs or divert the
attention of our technical personnel from our product development efforts. To
the extent any such problems require us to replace such hardware or software, we
may not be able to do so on acceptable terms, if at all.

                                       10
<PAGE>
TECHNOLOGICAL DEFECTS COULD DISRUPT OUR SERVICE, WHICH COULD HARM OUR BUSINESS
    AND REPUTATION.


    We face risks related to the technological capabilities of the LivePerson
service. We expect the number of simultaneous chats between our clients'
operators and Internet users over our system to increase significantly as we
expand our client base. Our network hardware and software may not be able to
accommodate this additional volume. Additionally, we must continually upgrade
our software to improve the features and functionality of the LivePerson service
in order to be competitive in our market. If future versions of our software
contain undetected errors, our business could be harmed. As a result of major
software upgrades at LivePerson, our client sites have, from time to time,
experienced slower than normal response times and interruptions in service. If
we experience system failures or degraded response times, our reputation and
brand could be harmed. We may also experience technical problems in the process
of installing and initiating the LivePerson service on new Web hosting services.
These problems, if unremedied, could harm our business.


    The LivePerson service also depends on complex software which may contain
defects, particularly when we introduce new versions onto our servers. We may
not discover software defects that affect our new or current services or
enhancements until after they are deployed. It is possible that, despite testing
by us, defects may occur in the software. These defects could result in:

    -  damage to our reputation;

    -  lost sales;

    -  delays in or loss of market acceptance of our products; and

    -  unexpected expenses and diversion of resources to remedy errors.


WE MAY BE UNABLE TO RESPOND TO THE RAPID TECHNOLOGICAL CHANGE AND CHANGING
    CLIENT PREFERENCES IN THE ONLINE SALES AND CUSTOMER SERVICE INDUSTRY AND
    THIS MAY HARM OUR BUSINESS.



    If we are unable, for technological, legal, financial or other reasons, to
adapt in a timely manner to changing market conditions in the online sales and
customer service industry or our clients' or Internet users' requirements, our
business, results of operations and financial condition would be materially and
adversely affected. Business on the Internet is characterized by rapid
technological change. In addition, the market for online sales and customer
service technology is relatively new. Sudden changes in client and Internet user
requirements and preferences, frequent new product and service introductions
embodying new technologies, such as broadband communications, and the emergence
of new industry standards and practices could render the LivePerson service and
our proprietary technology and systems obsolete. The rapid evolution of these
products and services will require that we continually improve the performance,
features and reliability of the LivePerson service. Our success will depend, in
part, on our ability to:


    -  enhance the features and performance of the LivePerson service;


    -  develop and offer new services that are valuable to companies doing
       business on the Internet and Internet users; and


    -  respond to technological advances and emerging industry standards and
       practices in a cost-effective and timely manner.


If any of our new services, including upgrades to the LivePerson service, do not
meet our clients' or Internet users' expectations, our business may be harmed.
Updating our technology may require significant additional capital expenditures
and could materially and adversely affect our business, results of operations
and financial condition.


                                       11
<PAGE>
IF WE ARE NOT COMPETITIVE IN THE MARKET FOR REAL-TIME SALES AND CUSTOMER SERVICE
    TECHNOLOGY, OUR BUSINESS COULD BE HARMED.

    There are no substantial barriers to entry in the real-time sales and
customer service technology market, other than the ability to design and build
scalable software and, with respect to outsourced solution providers, the
ability to design and build scalable network architecture. Established or new
entities may enter this market in the near future, including those that provide
real-time interaction online, with or without the user's request.


    We compete directly with companies focused on technology that facilitates
real-time sales and customer service interaction. Our competitors include
customer service enterprise software providers such as eGain Communications
Corp., eShare Technologies, Inc., Kana Communications, Inc. and WebLine
Communications (a part of Cisco Systems' applications technology group), some of
which are beginning to offer hosted solutions. Furthermore, many of our
competitors offer a broader range of customer relationship management products
and services than we currently offer. We may be disadvantaged and our business
may be harmed if companies doing business on the Internet choose sales and
customer service technology from such providers.


    We also face potential competition from larger enterprise software companies
such as Oracle Corporation and Siebel Systems. In addition, established
technology companies, including IBM, Hewlett-Packard and Microsoft, may also
leverage their existing relationships and capabilities to offer real-time sales
and customer service applications.

    Finally, we face competition from clients and potential clients that choose
to provide a real-time sales and customer service solution in-house as well as,
to a lesser extent, traditional offline customer service solutions, such as
telephone call centers.

    We believe that competition will increase as our current competitors
increase the sophistication of their offerings and as new participants enter the
market. Many of our current and potential competitors have:

    -  longer operating histories;

    -  larger client bases;

    -  greater brand recognition;

    -  more diversified lines of products and services; and

    -  significantly greater financial, marketing and other resources.

    These competitors may enter into strategic or commercial relationships with
larger, more established and better-financed companies. These competitors may be
able to:

    -  undertake more extensive marketing campaigns;

    -  adopt more aggressive pricing policies; and

    -  make more attractive offers to businesses to induce them to use their
       products or services.

    Any delay in the general market acceptance of the real-time sales and
customer service solution business model would likely harm our competitive
position. Delays would allow our competitors additional time to improve their
service or product offerings, and would also provide time for new competitors to
develop real-time sales and customer service applications and solicit
prospective clients within our target markets. Increased competition could
result in pricing pressures, reduced operating margins and loss of market share.

IF WE DO NOT SUCCESSFULLY INTEGRATE POTENTIAL FUTURE ACQUISITIONS, OUR BUSINESS
    COULD BE HARMED.

    In the future, we may acquire or invest in complementary companies, products
or technologies. Acquisitions and investments involve numerous risks to us,
including:


    -  difficulties in integrating operations, technologies, products and
       personnel with LivePerson;


    -  diversion of financial and management resources from efforts related to
       the LivePerson service or other then-existing operations;


    -  risks of entering new markets beyond providing real-time sales and
       customer service technology for companies doing business on the Internet;


    -  potential loss of either our existing key employees or key employees of
       any companies we acquire; and

    -  our inability to generate sufficient revenue to offset acquisition or
       investment costs.

    These difficulties could disrupt our ongoing business, distract our
management and employees, increase our expenses and adversely affect our results
of operations. Furthermore, we may incur debt or issue equity securities to pay
for any future acquisitions. The issuance of equity securities could be dilutive
to our existing stockholders.

WE COULD FACE ADDITIONAL REGULATORY REQUIREMENTS, TAX LIABILITIES AND OTHER
    RISKS AS WE EXPAND INTERNATIONALLY.

    We intend to expand internationally. There are risks related to doing
business in international markets, such as changes in regulatory requirements,
tariffs and other trade barriers, fluctuations in currency exchange rates and
adverse tax consequences. In addition, there are likely to be different consumer
preferences and requirements in specific international markets. Furthermore, we
may face difficulties in staffing and managing any foreign operations. One or
more of these factors could harm any future international operations.

OUR BUSINESS AND PROSPECTS WOULD SUFFER IF WE ARE UNABLE TO PROTECT AND ENFORCE
    OUR INTELLECTUAL PROPERTY RIGHTS.

    Our success and ability to compete depend, in part, upon the protection of
our intellectual property rights relating to the technology underlying the
LivePerson service. We currently have a U.S. patent application pending relating
to such technology and have not filed applications outside the U.S. It is
possible that:

    -  our pending patent application may not result in the issuance of a
       patent;

    -  any patent issued may not be broad enough to protect our intellectual
       property rights;

    -  any patent issued could be successfully challenged by one or more third
       parties, which could result in our loss of the right to prevent others
       from exploiting the invention claimed in the patent;

    -  current and future competitors may independently develop similar
       technology, duplicate our service or design around any patent we may
       have; and

    -  effective patent protection may not be available in every country in
       which we do business.

    We also rely upon copyright, trade secret and trademark law, written
agreements and common law to protect our proprietary technology, processes and
other intellectual property, to the extent that protection is sought or secured
at all. We currently have one patent application pending. To the extent that the
invention described in our U.S. patent application was made public prior to the
filing of the application, we may not be able to obtain patent protection in
certain foreign countries. We currently have a common law trademark,
"LivePerson", and three pending U.S. trademark applications. The trademark
examiner assigned to our applications has

                                       13
<PAGE>
issued non-final office actions with respect to our applications, requesting
additional information and making initial refusals. However, no final
determinations as to the registrability of the marks have been made. We are in
the process of responding to these office actions prior to their respective
deadlines, but ultimately we may not be able to secure registration of our
trademarks. In addition, we do not have any trademarks registered outside the
U.S., nor do we have any trademark applications pending outside the U.S. We
cannot assure you that any steps we might take will be adequate to protect
against infringement and misappropriation of our intellectual property by third
parties. Similarly, we cannot assure you that third parties will not be able to
independently develop similar or superior technology, processes or other
intellectual property. The unauthorized reproduction or other misappropriation
of our intellectual property rights could enable third parties to benefit from
our technology without paying us for it. If this occurs, our business, results
of operations and financial condition would be materially and adversely
affected. In addition, disputes concerning the ownership or rights to use
intellectual property could be costly and time-consuming to litigate, may
distract management from operating our business and may result in our loss of
significant rights.

                                       14
<PAGE>
OUR PRODUCTS AND SERVICES MAY INFRINGE UPON INTELLECTUAL PROPERTY RIGHTS OF
    THIRD PARTIES AND ANY INFRINGEMENT COULD REQUIRE US TO INCUR SUBSTANTIAL
    COSTS AND MAY DISTRACT OUR MANAGEMENT.

    Although we attempt to avoid infringing known proprietary rights of third
parties, we are subject to the risk of claims alleging infringement of
third-party proprietary rights. If we infringe upon the rights of third parties,
we may not be able to obtain licenses to use those rights on commercially
reasonable terms. In that event, we would need to undertake substantial
reengineering to continue offering our service. Any effort to undertake such
reengineering might not be successful. In addition, any claim of infringement
could cause us to incur substantial costs defending against the claim, even if
the claim is invalid, and could distract our management from our business.
Furthermore, a party making such a claim could secure a judgment that requires
us to pay substantial damages. A judgment could also include an injunction or
other court order that could prevent us from selling our products. If any of
these events occurred, our business, results of operations and financial
condition would be materially and adversely affected.

WE CANNOT PREDICT OUR FUTURE CAPITAL NEEDS TO EXECUTE OUR BUSINESS STRATEGY AND
    WE MAY NOT BE ABLE TO SECURE ADDITIONAL FINANCING.

    We believe that the net proceeds from this offering, together with the
proceeds from the sale of our series D redeemable convertible preferred stock,
and our current cash and cash equivalents, will be sufficient to fund our
working capital and capital expenditure requirements for at least the next
12 months. To the extent that we require additional funds to support our
operations or the expansion of our business, or to pay for acquisitions, we may
need to sell additional equity, issue debt or convertible securities or obtain
credit facilities through financial institutions. In the past, we have obtained
financing principally through the sale of preferred stock, common stock and
warrants. If additional funds are raised through the issuance of debt or
preferred equity securities, these securities could have rights, preferences and
privileges senior to holders of common stock. The terms of any debt securities
could impose restrictions on our operations. If additional funds are raised
through the issuance of additional equity or convertible securities, our
stockholders could suffer dilution. We cannot assure you that additional
funding, if required, will be available to us in amounts or on terms acceptable
to us. If sufficient funds are not available or are not available on acceptable
terms, our ability to fund our expansion, take advantage of acquisition
opportunities, develop or enhance our services or products, or otherwise respond
to competitive pressures would be significantly limited. Those limitations would
materially and adversely affect our business, results of operations and
financial condition.

OUR BUSINESS IS DEPENDENT ON A FEW KEY EMPLOYEES, INCLUDING OUR CHIEF EXECUTIVE
    OFFICER, ROBERT P. LOCASCIO.

    Our future success depends to a significant extent on the continued services
of our senior management team, including Robert P. LoCascio, our founder and
Chief Executive Officer. The loss of the services of any member of our senior
management team, in particular Mr. LoCascio, could have a material and adverse
effect on our business, results of operations and financial condition.


WE MAY BE LIABLE IF THIRD PARTIES MISAPPROPRIATE PERSONAL INFORMATION BELONGING
    TO OUR CLIENTS' INTERNET USERS.



    We maintain dialogue transcripts of the text-based chats between our clients
and Internet users and store on our servers information supplied voluntarily by
these Internet users in exit surveys which follow the chats. We provide this
information to our clients to allow them to perform Internet user analyses and
monitor the effectiveness of our service. Some of the


                                       15
<PAGE>

information we collect in text-based chats and exit surveys may include personal
information, such as contact and demographic information. If third parties were
able to penetrate our network security or otherwise misappropriate personal
information relating to our clients' Internet users or the text of customer
service inquiries, we could be subject to liability. We could be subject to
negligence claims or claims for misuse of personal information. These claims
could result in litigation which could have a material adverse effect on our
business, results of operations and financial condition. We may incur
significant costs to protect against the threat of security breaches or to
alleviate problems caused by such breaches.


PROBLEMS RESULTING FROM THE YEAR 2000 PROBLEM COULD REQUIRE US TO INCUR
    UNANTICIPATED EXPENSES, DIVERT MANAGEMENT'S TIME AND ATTENTION, AND DISRUPT
    OUR BUSINESS.

    Many currently installed computer systems and software products produced
before January 1, 2000 were coded to accept or recognize only two-digit entries
in the date code field. These systems may interpret the date code "00" as the
year 1900 rather than as the year 2000. As a result, computer systems and
software in use today may need to be upgraded or replaced to comply with Year
2000 requirements or risk system failure or miscalculations causing disruptions
of normal business activities. We are not aware of any material Year 2000
problems that have harmed or threaten to harm our business, but we cannot assure
you that no such problems will emerge. Our failure to correct a material Year
2000 problem could result in an interruption in, or a failure of, aspects of our
normal business activities or operations. In addition, a significant Year 2000
problem involving the LivePerson service, including our hosting facilities or
equipment provided to us by third-party vendors, could cause our clients to
consider seeking alternate solutions or cause an unmanageable burden on our
internal client service and network support staff. Any significant Year 2000
problem could require us to incur significant unanticipated expenses to remedy
these problems and could divert management from other tasks of operating our
business, which would harm our business, results of operations and financial
condition. Please see "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Year 2000" for more detailed information
regarding the Year 2000 issue.

DATA AND PROJECTIONS INCLUDED IN THIS PROSPECTUS RELATING TO THE GROWTH OF THE
    INTERNET ARE BASED ON ASSUMPTIONS THAT COULD TURN OUT TO BE INCORRECT, AND
    ACTUAL RESULTS COULD BE MATERIALLY DIFFERENT.


    This prospectus contains various third-party data and projections, including
those relating to Internet business activity. Our actual results or
circumstances may be materially different from the data or projections, and the
market that we address, namely real-time sales and customer service for
companies doing business on the Internet, may not grow. The failure of this
market to grow and, more generally, the failure of Internet business activity to
grow as projected, may cause the market price of our common stock to decline.


                         RISKS RELATED TO OUR INDUSTRY

WE ARE DEPENDENT ON CONTINUED GROWTH IN THE USE OF THE INTERNET AS A MEDIUM FOR
    COMMERCE.

    We cannot be sure that a sufficiently broad base of consumers will adopt,
and continue to use, the Internet as a medium for commerce. Our long-term
viability depends substantially upon the widespread acceptance and development
of the Internet as an effective medium for consumer

                                       16
<PAGE>
commerce. Use of the Internet to effect retail transactions is at an early stage
of development. Convincing our clients to offer real-time sales and customer
service technology may be difficult.

    Demand for recently introduced services and products over the Internet is
subject to a high level of uncertainty. Few proven services and products exist.
The development of the Internet into a viable commercial marketplace is subject
to a number of factors, including:

    -  continued growth in the number of users;

    -  concerns about transaction security;

    -  continued development of the necessary technological infrastructure;

    -  development of enabling technologies;

    -  uncertain and increasing government regulation; and

    -  the development of complementary services and products.

WE DEPEND ON THE CONTINUED VIABILITY OF THE INFRASTRUCTURE OF THE INTERNET.


    To the extent that the Internet continues to experience growth in the number
of users and frequency of use by consumers resulting in increased bandwidth
demands, we cannot assure you that the infrastructure for the Internet will be
able to support the demands placed upon it. The Internet has experienced outages
and delays as a result of damage to portions of its infrastructure. Outages or
delays, including those resulting from Year 2000 problems, could adversely
affect online sites, email and the level of traffic on the Internet. We also
depend on Internet service providers that provide our clients and Internet users
with access to the LivePerson service. In the past, users have experienced
difficulties due to system failures unrelated to our service. In addition, the
Internet could lose its viability due to delays in the adoption of new standards
and protocols required to handle increased levels of Internet activity.
Insufficient availability of telecommunications services to support the Internet
also could result in slower response times and negatively impact use of the
Internet generally, and our clients' sites (including the LivePerson pop-up
dialogue window) in particular. If the use of the Internet fails to grow or
grows more slowly than expected, if the infrastructure for the Internet does not
effectively support growth that may occur or if the Internet does not become a
viable commercial marketplace, we may not achieve profitability and our
business, results of operations and financial condition will suffer.


WE MAY BECOME SUBJECT TO BURDENSOME GOVERNMENT REGULATION AND LEGAL
    UNCERTAINTIES.

    Laws and regulations directly applicable to Internet communications,
commerce and advertising are becoming more prevalent. Recently, the United
States Congress enacted Internet legislation relating to issues such as
children's privacy, copyright and taxation. The children's privacy legislation
imposes restrictions on the collection, use and distribution of personal
identification information obtained online from children under the age of 13.
The copyright legislation establishes rules governing the liability of Internet
service providers and Web site publishers for the copyright infringement of
Internet users. The tax legislation places a moratorium on certain forms of
Internet taxes for three years; however, this moratorium does not apply to sales
and use taxes. Additionally, the European Union recently adopted a directive
addressing data privacy which imposes restrictions on the collection, use and
processing of personal data. Existing legislation and any new legislation could
hinder the growth in use of the Internet generally and decrease the acceptance
of the Internet as a medium for communication, commerce and advertising. The
laws governing the Internet remain largely unsettled, even in areas where
legislation has been enacted. It may take several years to determine whether and

                                       17
<PAGE>
how existing laws such as those governing intellectual property, taxation and
personal privacy apply to the Internet and Internet services. In addition, the
growth and development of the market for Internet commerce may prompt calls for
more stringent consumer protection laws, both in the U.S. and abroad, which may
impose additional burdens on companies conducting business online. Our business,
results of operations and financial condition could be materially and adversely
affected if we do not comply with recent legislation or laws or regulations
relating to the Internet that are adopted or modified in the future.


    For example, the LivePerson service allows our clients to capture and save
information about Internet users, possibly without their knowledge.
Additionally, our service uses a tool, commonly referred to as a "cookie," to
uniquely identify each of our clients' Internet users. To the extent that
additional legislation regarding Internet user privacy is enacted, such as
legislation governing the collection and use of information regarding Internet
users through the use of cookies, the effectiveness of the LivePerson service
could be impaired by restricting us from collecting information which may be
valuable to our clients. The foregoing could harm our business, results of
operations and financial condition.


SECURITY CONCERNS COULD HINDER COMMERCE ON THE INTERNET.

    User concerns about the security of confidential information online has been
a significant barrier to commerce on the Internet and online communications. Any
well-publicized compromise of security could deter people from using the
Internet or other online services or from using them to conduct transactions
that involve the transmission of confidential information. If Internet commerce
is inhibited as a result of such security concerns, our business would be
harmed.

                         RISKS RELATED TO THIS OFFERING

AFTER THIS OFFERING, OUR EXECUTIVE OFFICERS, DIRECTORS AND 5% OR GREATER
    STOCKHOLDERS WILL EXERCISE CONTROL OVER ALL MATTERS REQUIRING A STOCKHOLDER
    VOTE.

    After this offering, our executive officers, directors and existing
stockholders who each own greater than 5% of the common stock that was
outstanding immediately before this offering and their affiliates, each of whom
is listed in "Principal Stockholders," will, in the aggregate, beneficially own
approximately 70.7% of our outstanding common stock. As a result, these
stockholders will be able to exercise control over all matters requiring
approval by our stockholders, including the election of directors and approval
of significant corporate transactions. This concentration of ownership could
also have the effect of delaying or preventing a change in control.

OF OUR TOTAL OUTSTANDING SHARES, 25,323,804 ARE RESTRICTED FROM IMMEDIATE RESALE
    PURSUANT TO CONTRACTUAL AGREEMENTS AND PROVISIONS OF LAWS, BUT MAY BE SOLD
    INTO THE MARKET IN THE NEAR FUTURE. THE SALE OF THESE SHARES COULD CAUSE THE
    MARKET PRICE OF OUR COMMON STOCK TO DROP SIGNIFICANTLY, EVEN IF OUR BUSINESS
    IS DOING WELL.


    After this offering, we will have outstanding 29,323,804 shares of common
stock. Of these shares, the 4,000,000 shares sold in this offering will be
freely tradable except for any shares purchased by our "affiliates" as that term
is used in Rule 144 of the Securities Act, who are generally those persons who
directly or indirectly control LivePerson, such as our directors, executive
officers, and significant stockholders. Affiliates may only sell their shares
pursuant to the requirements of Rule 144 or in a registered public offering.
Unless sold earlier pursuant to a registered public offering, the remaining
25,323,804 shares will become available for resale in the public market at
various times in the future, including 20,586,962 shares that are eligible for


                                       18
<PAGE>

resale following the expiration of the 180-day lock-up agreements entered into
among the underwriters and such stockholders. Chase Securities Inc. may waive
the restrictions imposed in such agreements at any time. The following table
illustrates the shares eligible for sale in the public market:

      4,000,000         After the date of this prospectus, freely tradable shares
                        sold in this offering and shares saleable under Rule 144(k)
                        that are not subject to the 180-day lock-up

              0         After 90 days from the date of this prospectus, shares
                        saleable under Rule 144 or Rule 701 that are not subject to
                        the 180-day lock-up

      20,586,962        After 180 days from the date of this prospectus, the 180-day
                        lock-up is released and these shares are saleable under Rule
                        144 (subject, in some cases, to volume limitations), Rule
                        144(k) or Rule 701

      4,736,842         After 180 days from the date of this prospectus, restricted
                        securities that are held for less than one year are not yet
                        saleable under Rule 144
</TABLE>

    As restrictions on resale end, the market price of our stock could drop
significantly if the holders of restricted shares sell them or are perceived by
the market as intending to sell them. For more detailed information, see "Shares
Eligible for Future Sale."

THERE HAS BEEN NO PRIOR MARKET FOR OUR COMMON STOCK AND OUR STOCK PRICE MAY
    EXPERIENCE EXTREME PRICE AND VOLUME FLUCTUATIONS.

    Prior to this offering, investors could not buy or sell our common stock
publicly. An active public market for our common stock may not develop or be
sustained after the offering. The initial public offering price will be
determined by negotiations between us and the representatives of the
underwriters. The market price of our common stock may decline below the initial
public offering price after this offering.

    Fluctuations in market price and volume are particularly common among
securities of Internet and other technology companies. The market price of our
common stock may fluctuate significantly in response to the following factors,
some of which are beyond our control:

    -  variations in our quarterly operating results;

    -  changes in market valuations of Internet and other technology companies;

    -  our announcements of significant client contracts, acquisitions,
       strategic partnerships, joint ventures or capital commitments;

    -  our failure to complete significant sales;

    -  additions or departures of key personnel;

    -  future sales of our common stock; and

    -  changes in financial estimates by securities analysts.

    In the past, companies that have experienced volatility in the market price
of their common stock have been the object of securities class action
litigation. We may in the future be the target of similar litigation. Securities
litigation could result in substantial costs and distract management from other
aspects of operating our business.

                                       19
<PAGE>
WE MAY SPEND A SUBSTANTIAL PORTION OF THE NET PROCEEDS OF THIS OFFERING IN WAYS
    WITH WHICH YOU MAY NOT AGREE.

    The net proceeds of this offering are not allocated for specific uses. Our
management will have broad discretion to spend the net proceeds from this
offering in ways with which you may not agree. The failure of our management to
apply these funds effectively could result in unfavorable returns. This could
have a material and adverse effect on our business, results of operations and
financial condition, and could cause the price of our common stock to decline.

ANTI-TAKEOVER PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW MAY MAKE IT
    DIFFICULT FOR A THIRD PARTY TO ACQUIRE US.


    Provisions of our amended and restated certificate of incorporation, such as
our staggered board of directors, the manner in which director vacancies may be
filled and provisions regarding the calling of stockholder meetings, could make
it more difficult for a third party to acquire us, even if doing so might be
beneficial to our stockholders. In addition, provisions of our amended and
restated bylaws, such as advance notice requirements for stockholder proposals,
and applicable provisions of Delaware law, such as the application of business
combination limitations, could impose similar difficulties. Further, our amended
and restated certificate of incorporation and our amended and restated bylaws
may not be amended without the affirmative vote of at least 66.67% of our board
of directors or without the affirmative vote of not less than 66.67% of the
outstanding shares of our capital stock entitled to vote generally in the
election of directors (considered for this purpose as a single class) cast at a
meeting of our stockholders called for that purpose.


INVESTORS PURCHASING SHARES IN THIS OFFERING WILL SUFFER IMMEDIATE AND
    SUBSTANTIAL DILUTION.

    Investors purchasing shares in this offering will incur immediate and
substantial dilution in pro forma net tangible book value, in the amount of
$11.06 per share. To the extent outstanding options to purchase common stock are
exercised, there will be further dilution. Please see "Dilution."

                           FORWARD-LOOKING STATEMENTS

    This prospectus contains forward-looking statements which involve risks and
uncertainties. These forward-looking statements, which are usually accompanied
by words such as "may," "might," "will," "should," "could," "intends,"
"estimates," "predicts," "potential," "continue," "believes," "anticipates,"
"plans," "expects" and similar expressions, relate to, without limitation,
statements about our market opportunities, our strategy, our competition, our
projected revenue and expense levels and the adequacy of our available cash
resources. This prospectus also contains forward-looking statements attributed
to third parties relating to their estimates regarding Internet business
activity. You should not place undue reliance on these forward-looking
statements, which apply only as of the date of this prospectus. Our actual
results could differ materially from those expressed or implied by these
forward-looking statements as a result of various factors, including the risk
factors described above and included elsewhere in this prospectus. We undertake
no obligation to update publicly any forward-looking statements for any reason,
even if new information becomes available or other events occur in the future.

<PAGE>
                                USE OF PROCEEDS

    We estimate that we will receive net proceeds from the sale of the shares of
common stock in this offering of $51.1 million, assuming an initial public
offering price of $14.00 per share (the mid-point of the range set forth on the
cover page of this prospectus) and after deducting estimated underwriting
discounts and commissions and estimated offering expenses. If the underwriters
exercise their over-allotment option in full, we estimate that our net proceeds
will be $58.9 million.


    The primary purposes of this offering are to create a public market for our
common stock and facilitate future access to public capital markets. We
presently intend to use the proceeds for general corporate purposes, including
sales and marketing activities, the hiring of additional personnel, product
development costs and working capital. We also believe opportunities may exist
to expand our current business through strategic alliances and acquisitions, and
we may utilize a portion of the proceeds for such purposes. We are not currently
a party to any contracts or letters of intent with respect to any strategic
alliances or acquisitions.


    Pending such uses, we intend to invest the net proceeds of this offering in
short-term, interest-bearing, investment-grade securities.

                                DIVIDEND POLICY

    We have not declared or paid any cash dividends on our capital stock since
our inception. We intend to retain future earnings, if any, to finance the
operation and expansion of our business and do not anticipate paying any cash
dividends in the foreseeable future. Consequently, stockholders will need to
sell shares of common stock to realize a return on their investment, if any.

                                 CAPITALIZATION

    The following table sets forth our cash and cash equivalents, and
capitalization as of December 31, 1999:

    -  on an actual basis;

    -  on a pro forma basis to give effect to:

       -  the receipt of net proceeds of approximately $17.9 million from the
          sale of our series D redeemable convertible preferred stock on January
          27, 2000; and

       -  the automatic conversion into common stock of all of our outstanding
          convertible preferred stock (including the series D redeemable
          convertible preferred stock) at a two-for-three ratio upon the closing
          of this offering;

    -  on a pro forma as adjusted basis to give effect to the sale of 4,000,000
       shares of common stock by us in this offering at an assumed initial
       public offering price of $14.00 per share (the mid-point of the range set
       forth on the cover page of this prospectus), after deducting estimated

                                    DILUTION

    Our pro forma net tangible book value as of December 31, 1999 was
$34.2 million, or $1.37 per share. Pro forma net tangible book value per share
is determined by dividing the amount of our pro forma tangible net worth (pro
forma total tangible assets less total liabilities) by the number of shares of
our common stock outstanding after giving pro forma effect to the receipt of net
proceeds of approximately $17.9 million from the sale of our series D redeemable
convertible preferred stock on January 27, 2000 and to the automatic conversion
of each outstanding share of our convertible preferred stock into common stock
at a two-for-three ratio upon the closing of this offering. Dilution in pro
forma net tangible book value per share represents the difference between the
amount per share paid by investors in this offering and the net tangible book
value per share of common stock immediately after the completion of this
offering. After giving effect to our sale of 4,000,000 shares offered hereby at
an assumed initial public offering price of $14.00 per share (the mid-point of
the range set forth on the cover page of this prospectus) and after deducting
estimated underwriting discounts and commissions and estimated offering expenses
and the application of the estimated net proceeds therefrom, our pro forma net
tangible book value as of December 31, 1999 would have been $85.3 million, or
$2.94 per share. This represents an immediate increase in pro forma net tangible
book value of $1.57 per share to existing stockholders and an immediate dilution
in pro forma net tangible book value of $11.06 per share to new investors. The
following table illustrates this per share dilution:

consideration paid to us and the average price per share paid to us by existing
stockholders and by new investors who purchase shares of common stock in this
offering, before deducting the estimated underwriting discounts and commissions
and estimated offering expenses, assuming an initial public offering price of
$14.00 per share (the mid-point of the range set forth on the cover page of this

    The foregoing tables and calculations assume no exercise of any stock
options or warrants outstanding as of December 31, 1999. Specifically, these
tables and calculations exclude:

    -  10,000,000 shares of common stock reserved for issuance under our 2000
       Stock Incentive Plan, of which 5,528,970 shares are issuable upon the
       exercise of stock options outstanding as of March 8, 2000 with a weighted
       average exercise price of $2.28 per share;

                                       25

    -  93,750 shares of common stock issued upon the exercise of options since

    -  94,500 shares of common stock reserved for issuance upon the exercise of
       stock options with an exercise price of $1.60 per share granted outside

    -  450,000 shares of common stock reserved for issuance under our 2000

       of $1.60 per share; and

    -  175,781 shares of common stock issued upon the exercise of warrants since
       December 31, 1999.

    To the extent that any of these options or warrants are exercised, there
will be further dilution to new investors.

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

    THE FOLLOWING DISCUSSION OF OUR FINANCIAL CONDITION AND RESULTS OF
OPERATIONS SHOULD BE READ TOGETHER WITH OUR CONSOLIDATED FINANCIAL STATEMENTS
AND THE RELATED NOTES, WHICH APPEAR ELSEWHERE IN THIS PROSPECTUS. THE FOLLOWING
DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS THAT REFLECT OUR CURRENT PLANS,
ESTIMATES AND BELIEFS AND INVOLVE RISKS AND UNCERTAINTIES. OUR ACTUAL RESULTS
MAY DIFFER MATERIALLY FROM THOSE DISCUSSED IN THE FORWARD-LOOKING STATEMENTS.
FACTORS THAT COULD CAUSE OR CONTRIBUTE TO SUCH DIFFERENCES INCLUDE THOSE
DISCUSSED BELOW AND ELSEWHERE IN THIS PROSPECTUS, PARTICULARLY IN THE SECTION
ENTITLED "RISK FACTORS."

OVERVIEW


    We are a provider of technology that facilitates real-time sales and
customer service for companies doing business on the Internet. We are an
application service provider, and we offer our proprietary real-time interaction
technology as an outsourced service. We currently generate revenue from the sale
of our LivePerson service, which enables our clients to communicate directly
with Internet users via text-based chat. Our clients can respond to Internet
user inquiries in real time, and can thereby enhance their Internet users'
online shopping experience.


    Our business was incorporated in the State of Delaware in November 1995
under the name Sybarite Interactive Inc.; however, we did not commence
operations until January 1996. We had no significant revenue until 1997, when we
began to generate revenue from services primarily related to Web-based community
programming and media design.

    In 1998, we shifted our core business focus to the development of the
LivePerson service and phased out our prior programming efforts, which last
generated revenue in December 1999. We introduced the LivePerson service in
November 1998.


    In January 2000, we completed a private placement of 3,157,895 shares of our
series D redeemable convertible preferred stock with an affiliate of, and other
entities associated with, Dell Computer Corporation and with NBC Interactive
Media, Inc. (a division of NBC) at a purchase price of $5.70 per share. We
received net proceeds of approximately $17.9 million from this private
placement. Our series D redeemable convertible preferred stock will convert, at
a two-for-three ratio, into common stock upon the closing of this offering,
whereby each two shares of preferred stock will convert into three shares of
common stock. The common stock has an assumed value of $14.00 per share (the
mid-point of the range set forth on the cover page of this prospectus). In
connection with the issuance of our Series D redeemable convertible preferred
stock, we recorded a non-cash preferred stock dividend of $37.4 million, which
relates to the beneficial conversion feature associated with such preferred
stock.


    REVENUE


    With respect to the LivePerson service, our clients pay us an initial
non-refundable set-up fee, as well as a monthly fee for each seat. Our set-up
fee is intended to recover certain costs incurred by us (principally customer
service, training and other administrative costs) prior to deployment of our
service. Such fees are recorded as deferred revenue and recognized over a period
of 24 months, representing the estimated expected term of a client relationship.
As a result of recognizing set-up fees in this manner, combined with the fact
that we have more seats on an aggregate basis than clients, in 1999 revenue
attributable to our monthly service fee accounted for 96% of total LivePerson
service revenue. In addition, because we expect the aggregate number of seats to
continue to grow, we expect the set-up fee to represent a decreasing percentage
of total revenue over time. We do not charge an additional set-up fee if an
existing client adds more seats. We recognize monthly service revenue fees as
services are provided. Given


                                       28
<PAGE>

the time required to schedule training for our clients' operators and our
clients' resource constraints, we have historically experienced a lag between
signing a client contract and generating revenue from that client. This lag has
generally ranged from one day to 30 days.



    We also have begun to enter into contractual arrangements that complement
our direct sales force. These are primarily with Web hosting and call center
service companies, and are in the form of value-added reseller or referral
agreements pursuant to which the parties are paid a commission based on
generated revenue. Such commissions are paid and accounted for monthly, as
revenue is realized. Commissions generated under such agreements to date have
not, as a percentage of total LivePerson service revenue, been material,
although we expect such commissions to increase in both absolute terms and as a
percentage of total LivePerson service revenue over time.


    Prior to November 1998, when the LivePerson service was introduced, we
generated revenue from services primarily related to Web-based community
programming and media design. Revenue from such services was $245,000 for the
year ended December 31, 1997, $378,000 for the year ended December 31, 1998 and
$39,000 for the year ended December 31, 1999. As of January 2000, we no longer
generate any revenue from these services. Revenue generated from Web-based
community programming and media design services is recognized upon completion of
the project, provided that no significant obligations remain outstanding and
collection of the resulting receivable is probable.

    OPERATING EXPENSES

    Our cost of revenue associated with programming activity consisted primarily
of the personnel expenses associated with outsourced programming and design. We
no longer incurred these costs as of December 1998. We began developing the
LivePerson service in the third quarter of 1998. We did not allocate development
costs of the LivePerson service separately. Accordingly, since November 1998,
our cost of revenue has principally been associated with the LivePerson service
and has consisted of:

    -  compensation costs relating to employees who provide customer service to
       our clients, consisting of 17 people at December 31, 1999;

    -  compensation costs relating to our network support staff, consisting of
       five people at December 31, 1999;

    -  allocated occupancy costs and related overhead; and

    -  the cost of supporting our infrastructure, including expenses related to
       leasing space and connectivity for our services, as well as depreciation
       of certain hardware and software.

    Our product development expenses consist primarily of compensation and
related expenses for product development personnel, consisting of 15 people at
December 31, 1999, allocated occupancy costs and related overhead, and expenses
for testing new versions of our software. Product development expenses are
charged to operations as incurred.

    Our sales and marketing expenses consist of compensation and related
expenses for sales personnel and marketing personnel, consisting of 21 people at
December 31, 1999, allocated occupancy costs and related overhead, advertising,
sales commissions, marketing programs, public relations, promotional materials,
travel expenses and trade show exhibit expenses.

    Our general and administrative expenses consist primarily of compensation
and related expenses for executive, accounting and human resources personnel,
consisting of 15 people at December 31, 1999, allocated occupancy costs and
related overhead, professional fees, provision for doubtful accounts and other
general corporate expenses.

                                       29
<PAGE>

    In 1999, we increased our allowance for doubtful accounts from $15,000 to
$85,000, principally due to an increase in accounts receivable as a result of
the growth in our business. We base our allowance for doubtful accounts on
specifically identified known doubtful accounts plus a general reserve for
potential future doubtful accounts. We adjust our allowance for doubtful
accounts when accounts previously reserved have been collected.



    NON-CASH EXPENSES



    In 1998 and 1999, we recorded an aggregate of $25,000 and $978,000,
respectively, of non-cash expense in connection with our grants to consultants
of options to acquire an aggregate of 458,010 shares of common stock. The
expenses were determined using a Black-Scholes pricing model.



    In addition, during May 1999, we issued an option to purchase 94,500 shares
of common stock at an exercise price of $1.60 per share to ShopNow.com Inc., a
client, in connection with an agreement to provide the LivePerson service to
ShopNow for two years. As discussed below, the option was amended in February
2000. The original terms of the option provided that it would vest in or before
May 2001, if revenue generated by ShopNow met certain targets. At December 31,
1999, the total value ascribed to this option, using a Black-Scholes pricing
model, was $566,000, which was recorded as a deferred cost. In 1999, we
amortized $86,000 of this deferred cost.



    In February 2000, we amended the option agreement. Under the amendment, the
option became fully vested and immediately exercisable. ShopNow has agreed,
however, that it will not sell the underlying common stock until the earlier of
February 2005 and, if it has met certain amended revenue targets, between May
and June 2001. The value ascribed to the option at the time the option agreement
was amended, using a Black-Scholes pricing model, was $1.1 million. As a result,
in the first quarter of 2000, the value ascribed to the option, less the amount
previously amortized ($86,000), was immediately expensed because the options are
fully vested and because ShopNow has no continuing performance obligations to
complete in order to receive the options.



    Through March 8, 2000, we granted stock options to purchase 5,246,085 shares
of common stock to employees, of which options to purchase 5,164,710 shares of
common stock at a weighted average exercise price of $2.36 remained outstanding
at March 8, 2000. Certain of these options were granted at less than the deemed
fair value at the date of grant. The deemed fair value of our common stock
ranged from $0.67 to $13.00 for the period during which these options were
granted. In connection with the granting of these options, we recorded deferred
compensation of $6.2 million in 1999 and expect to record additional deferred
compensation of $17.9 million in the first quarter of 2000, representing the
difference between the deemed fair value of the common stock at the date of
grant for accounting purposes and the exercise price of the related options.
This amount will be recorded as deferred compensation in our financial
statements and will be amortized over the vesting period, typically three to
four years, of the applicable options. In 1999, we amortized $1.6 million of
deferred compensation. We expect to amortize the remaining deferred compensation
annually as follows:



    -  2000--$14.4 million, of which $5.2 million is expected to be recorded in
       the first quarter;



    -  2001--$4.9 million;



    -  2002--$2.5 million; and



    -  2003--$789,000.


                                       30

    In January 1999, we issued 41,667 shares of series A convertible preferred
stock in the amount of $50,000 in exchange for consulting services provided by
Silicon Alley Venture Partners, LLC.

RESULTS OF OPERATIONS

    Due to the phasing out of our programming services and our limited operating
history, we believe that comparisons of our 1999 operating results with those of
prior periods are not meaningful and that our historical operating results
should not be relied upon as indicative of future performance.

COMPARISON OF FISCAL YEARS ENDED DECEMBER 31, 1999 AND 1998

    REVENUE.  Total revenue increased to $639,000 in 1999, from $379,000 in
1998. Revenue associated with the LivePerson service increased to $600,000 in
1999 from $1,000 in 1998 and revenue associated with Web-based community
programming and media design services decreased to $39,000 in 1999 from $378,000
in 1998. We no longer provided these services as of January 2000; accordingly,
we believe period-to-period comparisons are not meaningful.

    COST OF REVENUE.  Cost of revenue increased to $856,000 in 1999, from
$70,000 in 1998. This increase was primarily attributable to $279,000 of costs
associated with the addition of client services staff as well as $65,000 of
depreciation of computer hardware and software. We did not incur any
depreciation expense in 1998 because we rented all of our equipment during that
period, the total cost of which was not significant.

    PRODUCT DEVELOPMENT.  Product development costs increased to $1.6 million
for 1999, from $93,000 in 1998. This increase was primarily attributable to
$809,000 associated with an increase in the number of LivePerson service product
development personnel, which grew from four to 15 people in 1999, and $342,000
of technology development activities related to the LivePerson service,
consisting of network architecture and software design expenses.

    SALES AND MARKETING.  Sales and marketing expenses increased to
$4.0 million for 1999, from $33,000 in 1998. This increase was primarily
attributable to $1.1 million associated with an increase in salaries and related
expenses resulting from an increase in sales and marketing personnel, which grew
from two to 21 people in 1999, and to an increase in advertising and promotional
expenses of $1.9 million, both of which related to the LivePerson service.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
to $1.7 million for 1999, from $178,000 in 1998. This increase was due primarily
to $711,000 associated with increases in personnel expenses related to support
and administration, occupancy costs, and to an increase of $339,000 in
recruitment costs, principally for our officers. The number of our executive,
accounting and human resources personnel grew from one to 15 in 1999.


    NON-CASH EXPENSES.  In 1999, non-cash expenses represented amortization of
deferred compensation of $1.6 million and non-cash expense incurred in
connection with options and preferred stock issued to non-employees in lieu of
payment for services rendered of $1.1 million.


    OTHER INCOME.  Interest income amounted to $474,000 for 1999, and consists
of interest earned on cash and cash equivalents generated by the receipt of
proceeds from our preferred stock issuances. Other income in 1998, representing
interest earned on cash balances, was less than $500.


    NET LOSS.  Our net loss increased to $9.8 million for 1999, from $20,000 in
1998.

COMPARISON OF FISCAL YEARS ENDED DECEMBER 31, 1998 AND 1997

    REVENUE.  Revenue increased to $379,000 in 1998 from $245,000 in 1997. This
increase was due to an increase in revenue associated with Web-based community
programming and media design.

    COST OF REVENUE.  Cost of revenue decreased to $70,000 in 1998 from $121,000
in 1997. This decrease was primarily attributable to a reduction of outsourced
programming and design and related expenses as we performed more functions
internally at lower costs.

    PRODUCT DEVELOPMENT.  Product development costs increased to $93,000 in 1998
from $0 in 1997. This increase was primarily due to the hiring of our product
development staff related to our programming services.

    SALES AND MARKETING.  Sales and marketing expenses increased to $33,000 in
1998 from $0 in 1997. This increase was primarily due to our initiating the
sales and marketing efforts related to our programming services.

    GENERAL AND ADMINISTRATIVE.  General and administrative costs increased to
$178,000 in 1998 from $130,000 in 1997. This increase was primarily due to
increases in personnel expenses and occupancy costs incurred as our operations
grew.

    NET LOSS.  Our net loss increased to $20,000 in 1998 from $6,000 in 1997.

QUARTERLY RESULTS OF OPERATIONS

    The following table sets forth, for the periods indicated, our financial
information for the four most recent quarters ended December 31, 1999. In our
opinion, this unaudited information has been prepared on a basis consistent with
our annual financial statements and includes all adjustments, consisting only of
normal recurring adjustments, necessary for a fair presentation of the unaudited
information for the periods presented. This information should be read in
conjunction with the financial statements, including the related notes, included
elsewhere in this prospectus. The results of operations for any quarter are not
necessarily indicative of results that we may achieve for any subsequent
periods.

    Our revenue from the LivePerson service has increased in each of the last
four quarters, from $15,000 to $414,000, due primarily to increased market
acceptance of our service, which is in part attributable to the growth of our
direct sales force. The growth of our sales force has allowed us to solicit more
prospective clients and to respond more quickly and effectively to their
inquiries. We cannot assure you that we will achieve similar growth in future
periods.

    Programming revenue, which has decreased from $9,000 to $3,000 during the
last four quarters, represents income from business activities which we are no
longer pursuing. We do not anticipate any significant programming revenue in the
future.

    Our total operating expenses have increased significantly in absolute terms
in each of the last four quarters, increasing from $422,000 to $5.1 million. As
a percentage of revenue, operating expenses declined slightly over the period.
We expect our operating expenses to continue to increase as we expand our
business.

    The increase in our cost of revenue has been primarily due to the addition
of client services personnel and the expansion of our technological
infrastructure. We expect the cost of our client services department to continue
to increase as we continue to hire additional personnel. We also expect to
continue to expend significant amounts to expand our technological
infrastructure and to incur increased depreciation expenses related to such
spending. As a result, we expect cost of revenue as a percentage of revenue to
increase in the short term.

    Product development costs increased significantly in absolute dollar terms
in each of the last four quarters, from $139,000 to $873,000, principally as a
result of increased headcount and allocated occupancy costs and related
overhead. As a percentage of revenue, however, product development costs in each
of the three quarters declined.

    Our sales and marketing expense has increased significantly in each of the
last four quarters, from $51,000 to $2.1 million, due to increases in the size
of our sales and marketing staff and an increase in marketing-related
activities. The increase in sales staff headcount is attributable to

                                       33
<PAGE>
the expansion of our sales efforts. The increase in our marketing headcount and
related expenses is due to our increasing efforts to enhance our brand
recognition. We expect sales and marketing expense to continue to increase as we
expand our business.

    General and administrative costs increased in absolute dollar terms in each
of the last four quarters, from $158,000 to $937,000, principally due to an
increase in the number of employees and, to a lesser extent, to professional
fees. We expect general and administrative costs to increase in connection with
our becoming a public company and as our business grows.

    Other income (expense), which is principally comprised of interest income
earned on cash and cash equivalents, has increased in each of the last four
quarters. The increase, particularly in the third quarter of 2000, is due
primarily to interest earned on the net proceeds from the July 1999 private
placement of our series C redeemable convertible preferred stock. We expect
interest income to increase with the investment of the proceeds from the
issuance of our series D redeemable convertible preferred stock and of this
offering in short-term, interest-bearing, investment-grade securities, pending
our use of such proceeds.

    The increase in non-cash compensation expense during 1999 was due to
deferred compensation recognized in connection with employee options and
compensation expense incurred in connection with options and preferred stock
issued to non-employees in lieu of payment for services rendered.

    We have experienced substantial increases in our expenses since our
introduction of the LivePerson service and we anticipate that our expenses will
continue to grow in the future. Although our revenue from the LivePerson service
has grown in each of the quarters since its introduction, we cannot assure you
that we can sustain this growth or that we will generate sufficient revenue to
achieve profitability. Consequently, we believe that period-to-period
comparisons of our operating results may not be meaningful, and as a result, you
should not rely on them as an indication of future performance.

LIQUIDITY AND CAPITAL RESOURCES

    Since our inception, we have financed our operations principally through
cash generated by private placements of our convertible preferred stock. Through
December 31, 1999, we have raised a total of $23.5 million in aggregate net
proceeds in three private placements. As of December 31, 1999, we had
$14.9 million in cash and cash equivalents, an increase of $14.8 million from
December 31, 1998. In addition, on January 27, 2000, we issued 3,157,895 shares
of series D redeemable convertible preferred stock at $5.70 per share, raising
total net proceeds of approximately $17.9 million. Since December 31, 1999 we
have entered into two letters of credit, which serve as the security deposits
for our new leases of office space, in an aggregate amount of $2.3 million for
2000. We expect to enter into an additional letter of credit for $2.2 million in
2001.

    Net cash used in operating activities was $6.0 million for the year ended
December 31, 1999. Net cash provided by operating activities was $19,000 and
$42,000 for the years ended December 31, 1998 and 1997, respectively. Net cash
used in operating activities for the year ended December 31, 1999 consisted
primarily of net operating losses, depreciation expense, non-cash compensation
and changes in accounts receivable, prepaid expenses and other current assets,
security deposits, accounts payable and accrued expenses and deferred revenue.
Net cash provided by operating activities for the years ended December 31, 1998
and 1997 was primarily due to changes in accounts receivable, prepaid expenses
and other current assets, security deposits, accounts payable and accrued
expenses and deferred revenue, partially offset by net operating losses and
non-cash compensation charges.

                                       34
<PAGE>
    Net cash used in investing activities was $2.6 million for the year ended
December 31, 1999 and $0 for each of the years ended December 31, 1998 and 1997.
Net cash used in investing activities for the year ended December 31, 1999 was
related to purchases of property and equipment. There were no investments in
fixed assets for the years ended December 31, 1998 or 1997.

    Net cash provided by financing activities was $23.4 million for the year
ended December 31, 1999 and $78,000 for the year ended December 31, 1998. Net
cash used in financing activities was $34,000 for the year ended December 31,
1997. Net cash provided by financing activities for the year ended December 31,
1999 was attributable to proceeds from the sale of our convertible preferred
stock. Net cash provided by financing activities for 1998 was principally
attributable to $100,000 in proceeds from the issuance of a note payable, which
was converted into 83,333 shares of our series A convertible preferred stock in
January 1999. Net cash used in financing activities in 1997 was attributable to
an advance made to an officer.


    As of December 31, 1999, our principal commitments consisted of $70,000 due
per month under operating leases. During the year ending December 31, 2000, we
anticipate an increase in capital expenditures and lease commitments consistent
with our anticipated growth in operations, infrastructure and personnel. We do
not currently expect that our principal commitments for the year ended
December 31, 2000 will exceed $5.0 million.



    In the first quarter of 2000, we entered into two additional leases for
office space, one in San Francisco and one in New York City. The lease for our
San Francisco office space, entered into in February 2000, provides for annual
aggregate payments of $275,000. In February 2000, we also entered into a
sublease for approximately 8,000 square feet in New York City expiring in
September 2000, providing for annual aggregate payments of $238,000. In March
2000, we entered into a lease for an aggregate of approximately 83,500 square
feet on two floors at a location in New York City. The lease provisions with
respect to one floor, consisting of approximately 40,500 square feet, commence
in June 2000, with rent of approximately $1.4 million per year in the first
three years, $1.5 million per year in years four through seven and $1.6 million
per year in years eight through ten. The related security deposit is $2.0
million for the first three years, $1.3 million for years four through seven and
$670,000 for years eight through ten. The other floor consists of approximately
43,000 square feet, and the lease provisions relating to that floor commence in
August 2001, with rent of approximately $1.5 million per year in the first three
years, $1.6 million per year in years four through seven and $1.7 million per
year in years eight through ten. The related security deposit is $2.2 million
for the first three years, $1.5 million for years four through seven and
$747,000 for years eight through ten. At our option, we have provided the
security deposit by a letter of credit.



    We have incurred significant net losses and negative cash flows from
operations since inception, and as of December 31, 1999, had an accumulated
deficit of $9.8 million. These losses have been funded primarily through the
issuance of our convertible preferred stock. We intend to continue to invest
heavily in sales, marketing, promotion, technology and infrastructure
development as we grow. As a result, we expect to continue to incur operating
losses and negative cash flows for the foreseeable future.



    We believe that the net proceeds from the sale of our series D redeemable
convertible preferred stock and our current cash and cash equivalents will be
sufficient to meet our anticipated cash needs for working capital and capital
expenditures for at least the next 12 months. This is regardless of whether or
not the anticipated proceeds from this offering are received, and is based on
our current business plan. Thereafter, we anticipate that such amounts, together
with the net proceeds of this offering and cash generated from operations, if
any, will be sufficient to satisfy our liquidity requirements for the next 18
months. However, we cannot


                                       35
<PAGE>

assure you that we will not require additional funds prior to such time, and we
would then seek to sell additional equity or debt securities or seek alternative
sources of financing. If we are unable to obtain this additional financing, we
may be required to reduce the scope of our planned sales and marketing and
product development efforts, which could harm our business, financial condition
and operating results.


YEAR 2000

    The Year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any computer programs
or hardware that have date-sensitive software may recognize a date using "00" as
the year 1900 rather than the year 2000. Prior to January 1, 2000, there was a
great deal of concern that this could result in system failures or
miscalculations, causing disruptions of operations for any company using such
computer programs or hardware, including, among other things, a temporary
inability to process transactions, send invoices or engage in normal business
activities. Most reports to date, however, are that computer systems are
functioning normally and the compliance and remediation work accomplished
leading up to the Year 2000 was effective to prevent any problems. Computer
experts have warned, however, that there may still be residual consequences. We
cannot assure you that any Year 2000 problems will not disrupt our service and
thereby result in a decrease in sales of the LivePerson service, an increase in
allocation of resources to address Year 2000 problems or an increase in
litigation costs.

    We designed our internal systems as well as our software, hardware and
network architecture to be Year 2000 compliant, and we believe, based on our
initial reports, that such systems are Year 2000 compliant.

    To date, we have not experienced any significant problems relating to the
Year 2000 compliance of our major suppliers. However, we cannot assure you that
these suppliers will not experience a Year 2000 problem in the future. In the
event that any such suppliers experience a Year 2000 problem, and we are unable
to replace it with an alternate source, our business would be harmed.

    Our clients' online services may be affected by Year 2000 issues if they
need to expend significant resources to remedy a Year 2000 problem that may
arise. This may reduce funds available to purchase the LivePerson service.

    We have not incurred any significant expenses to date, and we do not
anticipate that the total costs associated with our Year 2000 remediation
efforts, including both expenses incurred and any to be incurred in the future,
will be material.

    It remains impossible to determine with complete certainty that all Year
2000 problems that may affect us have been identified or corrected. The number
of devices that could be affected and the interactions among these devices are
simply too numerous. In addition, no one can accurately predict how many Year
2000 problem-related failures will occur or the severity, duration or financial
consequences of these perhaps inevitable failures. As a result, we believe that
the following consequences, among others, are possible:

    -  operational inconveniences and inefficiencies for us, our suppliers and
       our clients that may divert management's time and attention from ordinary
       business activities; and

    -  some clients may postpone their purchases of our service and we will
       experience a decrease in revenue.

                                       36
<PAGE>
    Based on our initial assessment of our Year 2000 readiness, we do not
anticipate being required to implement any material aspects of a contingency
plan to address Year 2000 readiness of our critical operations.

RECENTLY ISSUED ACCOUNTING STANDARDS

    In April 1998, the American Institute of Certified Public Accountants
("AICPA") issued SOP No. 98-5, "Reporting on the Costs of Start-Up Activities,"
which provides guidance on the financial reporting of start-up costs. SOP 98-5
requires costs of start-up activities and organization costs to be expensed as
incurred. We adopted SOP 98-5 on January 1, 1999. As we had not capitalized such
costs, the adoption of SOP 98-5 did not have an impact on our consolidated
financial statements.

    In April 1998, AICPA issued Statement of position 98-1, "Accounting for the
Costs of Computer Software Developed or Obtained for Internal Use
("SOP 98-1")." SOP 98-1 provides guidance for determining whether computer
software is internal-use software and on accounting for the proceeds of computer
software originally developed or obtained for internal use and then subsequently
sold to the public. It also provides guidance on capitalization of the costs
incurred for computer software developed or obtained for internal use. We
adopted SOP 98-1 in the first quarter of 1999, which did not have a material
effect on our financial statements.

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including derivative instruments
embedded in other contracts, and for hedging activities. Subsequently, the FASB
issued SFAS No. 137 which deferred the effective date of SFAS No. 133. SFAS
No. 137 is effective for all fiscal quarters of fiscal years beginning after
June 15, 2000. We have not yet analyzed the impact of this pronouncement on our
financial statements.

OVERVIEW


    LivePerson is a provider of technology that facilitates real-time sales and
customer service for companies doing business on the Internet. We change the way
Web site owners communicate with Internet users by enabling live text-based
chat. Historically, Internet users have had limited ways to communicate with
online businesses to inquire about matters such as product features, transaction
security and shipping details. The LivePerson service enables our clients to
communicate with Internet users via text-based chat. They can respond to these
and other Internet user inquiries in real time via text-based chat, and can
thereby enhance online shopping experiences.



    We are an application service provider, and we offer our proprietary
real-time interaction technology as an outsourced service. Our technology
requires no software or hardware installation by our clients or Internet users.
We can implement our LivePerson service immediately following a two-hour
training session. Upgrades to the LivePerson service are automatic because they
are installed on our servers, without requiring action by either our clients or
Internet users. We also offer our clients the ability to add capacity whenever
requested.



    Based on feedback received from our clients, we believe that our service
offers our clients the opportunity to increase sales by answering Internet user
questions and solving Internet user problems at critical points in the buying
process. It also enables our clients to reduce customer service costs by
allowing them to enhance operating efficiency and to improve Internet user
response times. Further, information captured in transcripts of live text-based
interactions can be used by our clients to increase their responsiveness to
Internet user needs and preferences, thereby improving Internet user
satisfaction, loyalty and retention.



    We currently have more than 450 clients, including numerous online
retailers, online service providers and traditional offline businesses with a
Web presence. Our largest clients in the first two months of 2000 were GMAC's
ditech.com, Homelender.com, MyHome.com, National Discount Brokers, Neiman
Marcus, ShopNow, TradeCapture.com and WhatsHotNow.


INDUSTRY BACKGROUND

    The Internet is evolving from primarily a static information source to a
widely accepted medium for commerce. Approximately 850,000 businesses currently
offer goods, services and information over the Web, according to an eMarketer
report of December 1999. Competition among online businesses is intense, with
new companies launching commercial Web sites every day. eMarketer estimates that
the number of actively maintained business Web sites will grow to 2.3 million
worldwide by the year 2002.

    To compete effectively in this environment, online businesses are
increasingly striving to provide high quality service to attract and retain
customers. This increased focus is in turn leading to heightened expectations
for online service by Internet users. Whether to ask questions about product
features or transaction security, or to get help with completing an online
application, Internet users today expect effective, timely answers. Companies
that do not provide this level of service risk losing customers to competitors.


    Companies are also increasingly focused on gathering information to improve
responsiveness and increase the rate of conversion from Web visitor to buyer.
Online shoppers have many purchasing options, with easy access to competitive
pricing, feature and distribution information. According to a Forrester Research
report of June 1999, 70% of all online merchants experience sales conversion
rates of less than 2%. In this environment, online businesses that collect
substantial information about Internet users are better able to serve them
effectively. Internet


                                       38
<PAGE>

users feedback provides Web site owners with input on product and service
offerings, preferences and Web site usability.


    LIMITATIONS OF EXISTING SALES AND CUSTOMER SERVICE SOLUTIONS.  Online
businesses currently use several methods to provide service and support to, and
gather information from, Internet users. Common methods include toll-free
telephone call centers, email response systems and listings of frequently asked
questions and answers.


    Telephone support, while similar in some ways to an in-store experience,
typically requires that a person using the Internet with a single telephone line
log off the Web. Internet users, who know that competition is literally a
mouse-click away, may prefer to move quickly to a competitor's Web site rather
than take the time to place a telephone call and face a potentially lengthy wait
time.


    Email support eliminates the need for the Internet user to log off to make a
telephone call and may result in lower telecommunication and support costs for
online businesses; however, email does not satisfy the real-time needs of
Internet users who desire communication at key points in the shopping process.


    Frequently asked questions, though available to Internet users on demand,
are typically general in content and may also be unsuitable for transactions
involving expensive or complex products and services. Internet users may desire
the comfort of an active communication with a customer service representative
before actually making such a purchase. In addition, because frequently asked
questions provide only one-way communication, they provide a limited means for
companies to gather Internet user feedback.



    In order to provide high quality service to Internet users, companies
require an interaction solution that:


    -  provides real-time responses;

    -  maximizes sales opportunities;


    -  strengthens relationships with Internet users;



    -  allows companies to gather information to remain responsive to Internet
       user needs;


    -  can be implemented quickly and easily; and

    -  can be operated in a cost-effective manner.

THE LIVEPERSON SOLUTION


    LivePerson is a provider of technology that facilitates real-time sales and
customer service for companies doing business on the Internet. We are an
application service provider offering this technology as an outsourced service
to companies of all sizes. Our technology enables our clients to interact with
customers in real time at the user's request through live text-based chat. This
improves Web site communication and enhances the online shopping experience.


    To implement the LivePerson service, our clients simply place a
LivePerson-branded or custom-created icon on one or more pages of their Web
sites and give their operators access to our service via the Internet. When an
Internet user browsing a client's Web site desires assistance, the user simply
clicks on the icon. This causes a pop-up dialogue window to appear on the user's
screen. The Internet user and our client's operator then engage in a real-time
online conversation in this dialogue window. The operator may incorporate
graphics and links to Web pages into the dialogue window. Our service enables
this live conversation by linking the Internet user and our clients' operators
through our proprietary technology, which resides on our servers.

                                       39
<PAGE>

    We create and store conversation transcripts and related data, and we also
enable our clients to generate optional Internet user exit surveys, which our
clients can use to collect additional information about Internet users. Stored
data include the Internet user's name, browser type, Internet Protocol (IP)
address and responses to exit surveys, the operator's identity and time stamps
for each chat transmission. In addition, we provide our clients with tools to
analyze the stored information. These tools include summary reports of the
number of chats in certain periods and the duration of such chats, filters to
sort data from exit surveys, statistical summaries of those data and statistical
summaries of operator performance.


    We believe the LivePerson service gives our clients the opportunity to:


    -  MAXIMIZE SALES OPPORTUNITIES. Our clients are able to respond to Internet
       user inquiries in real time. Live interaction with Internet users creates
       opportunities to:



       -  answer questions on demand and resolve Internet user issues as they
          occur;


       -  assist in closing sales that might otherwise have been abandoned
          without direct one-to-one real-time interaction; and

       -  market additional products and services in order to increase average
          order sizes.


    -  STRENGTHEN RELATIONSHIPS WITH INTERNET USERS. Personalized service
       generates increased Internet user satisfaction. Our service enables our
       clients to build relationships with Internet users and offers our clients
       the opportunity to market to Internet users on a one-to-one basis.
       Furthermore, transcripts from LivePerson conversations and optional exit
       surveys often provide relevant Internet user data and valuable real-time
       feedback. Our clients may then use this information to modify product
       offerings and marketing efforts, improve Web site navigation and refine
       their frequently asked questions listings.



    -  REDUCE OPERATING COSTS. Our clients' experience has shown that a single
       operator can interact with as many as four users simultaneously. As a
       result, an operator can provide service to more Internet users, thereby
       reducing costs per interaction. In addition, our clients can create
       pre-formatted responses to Internet user questions, allowing them to
       improve response time and operator efficiency. An operator can simply
       choose and, where appropriate, slightly modify a pre-formatted response
       to answer many questions.



    Because we are an application service provider and provide our clients with
a service rather than an in-house technology solution, we provide our clients
with the following additional benefits:


    -  LOW SET-UP COSTS AND REASONABLE ONGOING FEES. We charge our clients a low
       set-up fee and reasonable ongoing monthly fees.

    -  EFFECTIVE USE OF INTERNAL RESOURCES. Because the LivePerson service is an
       outsourced application, our clients can devote their information
       technology resources to other priorities.


    -  RAPID DEPLOYMENT. We provide the technology needed to facilitate
       real-time sales and customer service without plug-ins or customization.
       Our clients do not need to install any hardware or software in order to
       immediately provide the LivePerson service, other than any hardware or
       software they might need to install in order to connect to the Internet
       generally. In addition, our clients' operators and Internet users can use
       our service with any standard Web browser.



    -  AUTOMATIC UPGRADES. We install all upgrades to the LivePerson service on
       our servers. As a result, upgrades are immediately available for use and
       require no action by either our clients or Internet users.


    -  EASE OF EXPANSION. Our clients can add additional operator seats simply
       by requesting them, enabling the LivePerson service to meet our clients'
       growth needs.

OUR STRATEGY


    Our objective is to enhance our current position as a provider of real-time
sales and customer service technology for companies doing business on the
Internet. The key elements of our strategy include:



    STRENGTHENING OUR MARKET POSITION AND GROWING OUR RECURRING REVENUE
BASE.  We intend to extend our market position by significantly increasing our
installed client base. We intend to capitalize on our growing base of existing
clients by selling them additional seats and other services as Internet users
are increasingly exposed to the benefits and functionality of live text-based
interaction. Increasing our client base will enable us to continue to strengthen
our recurring revenue stream. We also believe that greater exposure of Internet
users to our service will create additional demand for real-time sales and
customer service solutions. We plan to continue expanding into all areas of
Internet commerce which could benefit from real-time sales and customer service
technology.


    INCREASING THE VALUE OF OUR SERVICE TO OUR CLIENTS.  We strive to
continuously add new features and functionality to our live interaction
platform. Because we host our service, we can make new features available
immediately to our clients without client or end-user installation of software
or hardware. We currently offer a suite of reporting and administrative tools as
part of the LivePerson service. Over time, we intend to develop richer tools for
appropriate sectors of our client base, while adding further interactive
capabilities. We also intend to develop additional services that will provide
value to our clients. For example, we intend to provide advisory services to our
clients that enable improved reporting capabilities, data storage and bridges to
existing client systems. Our clients may use these capabilities to increase
productivity, manage call center staffing, develop one-to-one marketing tactics
and pinpoint sales opportunities. Through these and other initiatives, we intend
to increase the value of our service to clients and their reliance on its
benefits, which we believe will result in additional revenue from both new and
existing clients over time.


    CONTINUING TO BUILD STRONG BRAND RECOGNITION.  The LivePerson brand name is
prominently displayed on the pop-up dialogue window that appears when an
Internet user has requested assistance. We believe that high visibility
placement of our brand name will create greater brand awareness and increase
demand for the LivePerson service. In addition, we intend to leverage increasing
awareness of our brand and our reputation as a provider of real-time sales and
customer service technology to become a well-recognized solution for companies
doing business on the Internet. We intend to expand our traditional and online
marketing activities to achieve these goals.


    MAINTAINING OUR TECHNOLOGICAL LEADERSHIP POSITION.  We focus on the
development of tightly integrated software design and network architecture that
is both reliable and scalable. We continue to devote significant resources to
technological innovation. Specifically, we plan to expand the features and
functionality of our existing service, develop broader applications for our
service and create new products and services that will benefit our expanding
client base. We evaluate emerging technologies and industry standards and
continually update our technology in response to changes in the real-time
customer service industry. We believe that these efforts will allow us to
effectively anticipate changing client and end-user requirements in our rapidly
evolving industry.

    EVALUATING STRATEGIC ALLIANCES AND ACQUISITIONS WHERE APPROPRIATE.  We
intend to seek opportunities to form strategic alliances with or to acquire
other companies that will enhance our business. We have entered into selected
strategic alliances with customer service call centers and may enter into
additional alliances in the future. We have no present plans or commitments with

                                       41
<PAGE>
respect to any strategic alliances or acquisitions and we are not currently
engaged in any material negotiations with respect to these opportunities.

    EXPANDING OUR INTERNATIONAL PRESENCE.  We currently have more than 35
non-U.S. based clients in Europe, Asia, South America and the Middle East, all
of which were sold and are serviced by our U.S. offices. We have also translated
the user interface for the LivePerson service into a variety of languages,
presently including Dutch, French, German, Italian, Portuguese, Spanish and
Swedish, and are currently making them available for our international clients.
We intend to expand our international presence to better penetrate these markets
and are evaluating strategies to implement international expansion.

THE LIVEPERSON SERVICE


    The LivePerson service appears on our clients' Web sites as a
LivePerson-branded or custom-created icon. An Internet user browsing a client's
Web site who desires assistance simply clicks on the icon, causing the
LivePerson pop-up dialogue window to appear on the user's screen. An operator
prompts the user with an offer of assistance, commencing a live text-based
interaction. In many instances, pre-formatted responses are used to respond to
Internet user inquiries.


    In addition, an operator may offer hyperlinks to other parts of a client's
Web site, product photos and graphics in the dialogue window. This allows an
operator to easily present additional products or services, thereby maximizing
sales opportunities.


    The LivePerson technology consists of five integrated components that
form a comprehensive real-time interaction platform. We currently offer the
features and functionality outlined below to all clients and intend to add more
features in the future. These may include additional reporting and
administrative tools, new interactive capabilities and data bridges to existing
client systems.

              INTERNET USER INTERACTION.  The Internet user interaction
              component is the core of real-time communication between our
              clients' operators and Internet users.



               -  REAL-TIME TEXT-BASED INTERACTION. Real-time text-based
                  interaction is the communication vehicle between our clients'
                  operators and Internet users. Text is currently the preferred
                  method of communication because it requires no special
                  plug-ins or hardware and it can be stored and analyzed.



               -  IMAGE / LINK / PAGE PRESENTER. An operator may present
                  photographs, images or links to other Web pages or sites in
                  the dialogue window in response to Internet user queries. An
                  operator may also "push" Web pages to an Internet user's
                  screen.



               -  SHOPPING CART CONVERTER. The shopping cart converter is a
                  pop-up window feature that is often used to help prevent
                  shopping cart abandonment. Typically, after an Internet user
                  has been at a shopping cart for a set period, a pop-up window
                  will appear offering assistance. This enables the Internet
                  user to instantly ask a question before completing or
                  potentially abandoning a transaction.



               -  EXIT SURVEY. A customizable exit survey is presented to the
                  Internet user after each conversation. The survey can be
                  modified in real time and is used by our clients primarily for
                  gathering Internet user feedback, creating Internet user
                  profiles and quality control.
[GRAPHIC APPEARS HERE]
The graphic, positioned to the left of the text, is a larger cube positioned
upon a smaller three-dimensional cube, with the number 2 in the larger cube.



              DIRECT MARKETING.  The direct marketing component enables Web site
              owners to classify Internet users and target outbound email to
              selected groups.



               -  GROUP PROFILER. The group profiler provides administrators
                  with the power to analyze, profile and classify Internet users
                  based on various data collected in an exit survey. This is
                  used by the administrator to understand Internet user patterns
                  and to create Internet user groups.



               -  EMAIL TARGETER. Based on information collected in exit
                  surveys, the email targeter allows clients to target sales and
                  marketing campaigns to selected Internet user groups.
[GRAPHIC APPEARS HERE]
The graphic, positioned to the left of the text, is a larger cube positioned
upon a smaller three-dimensional cube, with the number 3 in the larger cube.



              OPERATOR CONTROL.  The operator control component enables
              operators to efficiently manage interactions with multiple
              Internet users.



               -  SKILL-BASED ROUTING. Internet users can be routed to specific
                  operators based on the operator's particular knowledge of
                  specific products or services. For example, many of our
                  clients have specialized operator groups focusing separately
                  on sales or customer service to whom they selectively route
                  inquiries. This routing complements and partially automates
                  the alternative operator transfer capability.



               -  ALTERNATIVE OPERATOR TRANSFER. The operator can transfer an
                  Internet user to another operator or to an administrator with
                  unique skills or knowledge.



               -  PRE-FORMATTED RESPONSES. The operator can use and modify
                  pre-formatted responses to assist in responding to an Internet
                  user, rather than manually typing a response. Pre-formatted
                  responses are usually created by administrators and may be
                  accessed and modified on a real-time basis to


                                       43
<PAGE>

                  continuously improve response time and quality. Operators
                  preview and may edit pre-formatted responses to respond
                  appropriately to Internet user inquiries.

[GRAPHIC APPEARS HERE]
The graphic, positioned to the left of the text, is a larger cube positioned
upon a smaller three-dimensional cube, with the number 4 in the larger cube.

              ADMINISTRATOR CONTROL.  The administrator control component
              enables administrators to manage operators.

               -  OPERATOR EVALUATION TOOL. The administrator can view operator
                  call activity by date, time, length and number of dialogues,
                  and operator response time, enabling real time operator
                  evaluation.


               -  REAL-TIME OPERATOR CONTROL CENTER. The administrator can view
                  the conversations between all operators online and Internet
                  users. Administrators can also participate in conversations to
                  help operators respond to inquiries.

The graphic, positioned to the left of the text, is a larger cube positioned
upon a smaller three-dimensional cube, with the number 5 in the larger cube.



              INTERNET USER DATA COLLECTION.  The Internet user data collection
              component captures, stores and processes all Internet user
              information.



               -  TEXT-BASED TRANSCRIPTS. All textual data, including exit
                  survey data, are archived in an indexed database which can be
                  queried on several criteria. Multiple transcripts from
                  conversations with the same Internet user are saved within one
                  record set, ensuring that an exact history of the Internet
                  user's interaction is accurately maintained. Transcripts of
                  prior conversations can be viewed by operators in real time as
                  they interact with Internet users.



               -  LAST-PAGE VIEWED TRACKER. The specific page that the Internet
                  user viewed before entering into a LivePerson text-based
                  interaction is captured and saved with the transcript of the
                  dialogue.



               -  BROWSER / IP ADDRESS TRACKER. The Internet user's browser type
                  and IP address are captured and saved with the transcript of
                  the dialogue.


               -  EXIT SURVEY ANALYZER. Survey results and summaries can be
                  instantly displayed, queried and graphed.

SALES, CLIENT SUPPORT AND MARKETING


    SALES.  The sales cycle for the LivePerson service has historically been 30
to 45 days, but has recently been shorter than that. We sell LivePerson
primarily via telephone as a monthly fee service. Due to the relatively low
start-up costs of the LivePerson service, our experience has shown that purchase
approval comes from customer service, sales or marketing managers, and requires
little or no involvement on the part of a client's information technology staff.


    We sell primarily through a direct sales organization and target companies
seeking to improve customer relations and increase Internet commerce activity.
Additionally, potential clients have contacted us as a result of our
participation in trade shows, press releases, news articles, online and offline
advertising campaigns or visits to our Web site. We demonstrate the LivePerson
service online and, for larger accounts, we provide in-person service
demonstrations.


    We also have begun to enter into contractual arrangements that complement
our direct sales force. These are primarily with Web hosting and call center
service companies, and are in the form of value-added reseller or referral
agreements pursuant to which the parties are paid a commission based on
generated revenue. Such commissions are paid and accounted for monthly, as
revenue is realized. Commissions generated under such agreements to date have
not, as a percentage of total LivePerson service revenue, been material,
although we expect such commissions to increase in both absolute terms and as a
percentage of total LivePerson service revenue over time.


    CLIENT SUPPORT.  Our client services group assists the client in launching
the LivePerson service, and manages our ongoing relationship with the client.
Each client is assigned a client services manager who is responsible for
day-to-day client interaction.

                                       46
<PAGE>
    The following steps are required to launch a new LivePerson client:

    -  ACCOUNT SETUP. We create operator names and passwords for our client.

    -  SITE SETUP. Our client places our HTML link on its Web site.

    -  TRAINING. We provide telephone-based training of operators and
       administrators.

    Setup and training can generally be accomplished within the same day. We
also maintain a 24-hour per day / seven-day per week help desk to assist clients
with any technical concerns or issues.


    MARKETING.  Our marketing strategy is focused on building brand awareness of
LivePerson as a provider of real-time sales and customer service technology for
companies doing business on the Internet. Our marketing targets dedicated
Internet companies, Fortune 1000 companies and other companies with established
commercial Web sites.


    Our strategic advertising campaigns utilize both traditional and online
media. Our print advertising focuses on targeted trade publications, including
Internet commerce and other categories, while our online advertising targets
decision makers of companies doing business on the Internet. We also exhibit
prominently at key industry trade shows.

    Our marketing strategy also includes aggressive public relations efforts.
These initiatives include interviews with media and industry analysts which
often result in published articles and studies. They also include speaking
engagements and byline articles featuring our executives.

COMPETITION

    The market for real-time sales and customer service technology is new and
intensely competitive. There are no substantial barriers to entry in this
market, other than the ability to design and build scalable software and, with
respect to outsourced solution providers, the ability to design and build
scalable network architecture. Established or new entities may enter this market
in the near future, including those that provide real-time interaction online,
with or without the user's request.


    We compete directly with companies focused on technology that facilitates
real-time sales and customer service interaction. Our competitors include
customer service enterprise software providers such as eGain Communications
Corp., eShare Technologies, Inc., Kana Communications, Inc. and WebLine
Communications (a part of Cisco Systems' applications technology group), some of
which are beginning to offer hosted solutions. Furthermore, many of our
competitors offer a broader range of customer relationship management products
and services than we currently offer. We may be disadvantaged and our business
may be harmed if companies doing business on the Internet choose sales and
customer service technology from such providers.


    We also face potential competition from larger enterprise software companies
such as Oracle and Siebel Systems. In addition, established technology
companies, including IBM, Hewlett-Packard and Microsoft, may also leverage their
existing relationships and capabilities to offer real-time sales and customer
service applications.

    Finally, we face competition from clients and potential clients that choose
to provide a real-time sales and customer service solution in-house as well as,
to a lesser extent, traditional offline customer service solutions, such as
telephone call centers.

    We believe that competition will increase as our current competitors
increase the sophistication of their offerings and as new participants enter the
market. Many of our current and potential competitors have:

    -  longer operating histories;

                                       47
<PAGE>
    -  larger client bases;

    -  greater brand recognition;

    -  more diversified lines of products and services; and

    -  significantly greater financial, marketing and other resources.

    These competitors may enter into strategic or commercial relationships with
larger, more established and better-financed companies. These competitors may be
able to:

    -  undertake more extensive marketing campaigns;

    -  adopt more aggressive pricing policies; and

    -  make more attractive offers to businesses to induce them to use their
       products or services.

    Any delay in the general market acceptance of the real-time sales and
customer service solution business model would likely harm our competitive
position. Delays would allow our competitors additional time to improve their
service or product offerings, and would also provide time for new competitors to
develop real-time sales and customer service applications and solicit
prospective clients within our target markets. Increased competition could
result in pricing pressures, reduced operating margins and loss of market share.

TECHNOLOGY

    Three key technological features distinguish the LivePerson service:

    -  All of our customers share the same servers, databases, and network
       connections. We are therefore able to accommodate our expanding customer
       base and increasing system usage without incrementally adding new
       hardware or network infrastructure.

    -  Our network, hardware and software are designed to accommodate our
       clients' demand for high-quality 24-hours per day / seven-days per week
       service.

    -  As a hosted service we are able to add additional capacity and new
       features quickly and efficiently. This has enabled us to immediately
       provide these benefits simultaneously to our entire client base. In
       addition, it allows us to maintain a relatively short development and
       implementation cycle of several weeks.


As an application service provider, we focus on the development of tightly
integrated software design and network architecture. We have dedicated
significant resources to designing our software and network architecture based
on the fundamental principles of reliability and scalability.


    SOFTWARE DESIGN.  Our software design provides a reliable store-and-forward
message delivery solution that actively routes messages between operators and
Internet users.

    The LivePerson real-time interaction platform can efficiently accommodate
additional features and functionality due to its distributed processes, which
can be replicated on several servers. In some cases, key processes are run
independently to enhance performance. Our software design is also based on open
standards. These standard protocols facilitate integration with our clients'
legacy and third-party systems, and include:

    -  Java

    -  XML (Extensible Mark-up Language)

    -  HTML (Hypertext Mark-up Language)

    -  SQL (Structured Query Language)

                                       48
<PAGE>
    -  Internet Protocol (IP)

    NETWORK ARCHITECTURE.  The software underlying our service is integrated
with a scalable and reliable network architecture. Our network is scalable in
that we do not need to incrementally add new hardware or network capacity for
each new LivePerson client. This network architecture is supported by data
centers that have redundant network connections, servers and other features,
ensuring a high level of reliability.


    Our network architecture is also based on proprietary packet routing and
server clustering techniques and superior network connectivity. Requests are
routed among several servers dynamically to ensure uninterrupted service. In
addition, we use a "multi-homed" Internet access system, which incorporates
multiple direct Internet connections to reduce the impact of latency that may
occur on different parts of the Internet. This design enables our clients and
Internet users to efficiently connect to our servers.


    We also use advanced load-balancing techniques to ensure that each
LivePerson conversation is connected at an optimal speed and that no single
point of failure can affect the LivePerson service.

GOVERNMENT REGULATION


    We are subject to federal, state and local regulation, including laws and
regulations applicable to access to or commerce over the Internet. Due to the
increasing popularity and use of the Internet and various other online services,
it is likely that a number of new laws and regulations will be adopted with
respect to the Internet or other online services covering issues such as user
privacy, freedom of expression, pricing, content and quality of products and
services, taxation, advertising, intellectual property rights and information
security. The nature of such legislation and the manner in which it may be
interpreted and enforced cannot be fully determined and, therefore, such
legislation could subject us and/or our clients or Internet users to potential
liability, which in turn could have an adverse effect on our business, results
of operations and financial condition. The adoption of any such laws or
regulations might also impair the growth of Internet use, which in turn could
decrease the demand for our service or increase the cost of doing business or in
some other manner have a material adverse effect on our business, results of
operations and financial condition. In addition, applicability to the Internet
of existing laws governing issues such as intellectual property, taxation and
personal privacy is uncertain. The vast majority of such laws were adopted prior
to the advent of the Internet and related technologies and, as a result, do not
contemplate or address the unique issues of the Internet and related
technologies.



    As a result of collecting data from live online Internet user dialogues, our
clients may be able to analyze the commercial habits of Internet users. Privacy
concerns may cause Internet users to avoid online sites that collect such
behavioral information and even the perception of security and privacy concerns,
whether or not valid, may indirectly inhibit market acceptance of our services.
In addition, our clients may be harmed by any laws or regulations that restrict
their ability to collect or use this data. Several states have proposed
legislation that would govern the collection and use of personal user
information gathered online or require online services to establish privacy
policies. The Federal Trade Commission has initiated actions against online
services regarding the manner in which information is collected from users, used
by online services and/or provided to third parties, and has begun
investigations into the privacy practices of companies that collect information
about individuals on the Internet. The European Union has enacted its own
privacy regulations that may result in limits on the collection and use of some
user information. Changes to existing domestic or international laws or the
passage of new laws intended to address these or other issues, including some
recently proposed changes, could create uncertainty in the marketplace that
could reduce demand for our services or increase the cost of


                                       49
<PAGE>

doing business as a result of litigation costs or increased service delivery
costs, or could in some other manner have a material adverse effect on our
business, results of operations and financial condition.


    It may take years to determine how existing laws apply to the Internet. Any
new legislation or regulation regarding the Internet, or the application of
existing laws and regulations to the Internet, could harm us. Additionally, as
we expand outside the U.S., the international regulatory environment relating to
the Internet could have a material and adverse effect on our business, results
of operations and financial condition.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

    We rely upon a combination of patent, copyright, trade secret and trademark
law, written agreements and common law to protect our proprietary technology,
processes and other intellectual property, to the extent that protection is
sought or secured at all. We currently have one U.S. patent application pending.
To the extent that the invention described in our U.S. patent application was
made public prior to the filing of the application, we may not be able to obtain
patent protection in certain foreign countries. In addition, we have a common
law trademark, "LivePerson", and three pending U.S. trademark applications. The
trademark examiner assigned to our applications has issued non-final office
actions with respect to our applications, requesting additional information and
making initial refusals. However, no final determinations as to the
registrability of the marks have been made. We are in the process of responding
with respect to our applications, to these office actions prior to their
respective deadlines, but ultimately we may not be able to secure registration
of our trademarks. We do not have any trademarks registered outside the U.S.,
nor do we have any trademark applications pending outside the U.S.

    Although we rely on patent, copyright, trade secret and trademark law,
written agreements and common law, we believe that factors such as the
technological and creative skills of our personnel, new service developments,
frequent enhancements and reliable maintenance are more essential to
establishing and maintaining a technology leadership position. We cannot assure
you that others will not develop technologies that are similar or superior to
our technology. We enter into confidentiality and other written agreements with
our employees, consultants and strategic partners, and through written
agreements, control access to and distribution of our software, documentation
and other proprietary information. Despite our efforts to protect our
proprietary rights, third parties may, in an unauthorized manner, attempt to
copy or otherwise obtain and use our service or technology or otherwise develop
a service with the same functionality as our products. Policing unauthorized use
of our products is difficult, and we cannot be certain that the steps we have
taken will prevent misappropriation of our technology, particularly in foreign
countries where the laws may not protect proprietary rights as fully as do the
laws of the United States.

    Substantial litigation regarding intellectual property rights exists in the
software industry. Our service may be increasingly subject to third-party
infringement claims as the number of competitors in our industry segment grows
and the functionality of services in different industry segments overlaps. Some
of our competitors in the market for real-time sales and customer service
solutions may have filed or may intend to file patent applications covering
aspects of their technology. Although we believe that our service and technology
do not infringe upon the intellectual property rights of others and that we have
all rights necessary to utilize the intellectual property employed in our
business, we may be subject to claims alleging infringement of third-party
intellectual property rights. Any such claims could require us to spend
significant amounts in litigation, distract management from other tasks of
operating our business, pay damage awards, delay delivery of the LivePerson
service, develop non-infringing intellectual property or acquire licenses to the
intellectual property that is the subject of any such

                                       50
<PAGE>
infringement. Therefore, such claims could have a material adverse effect on our
business, results of operations and financial condition.

EMPLOYEES

    As of March 8, 2000, we had 125 full-time employees. Members of senior
management have entered into employment agreements with us, some of which are
described in "Management--Employment Agreements." None of our employees are
covered by collective bargaining agreements. We believe our relations with our
employees are good.

FACILITIES

    We currently lease an aggregate of approximately 25,000 square feet at our
headquarters location in New York City, consisting of a lease for approximately
17,000 square feet expiring in October 2006 and a sub-lease for approximately
8,000 square feet expiring in September 2000. We also have a lease for an
additional, approximately 6,000 square foot location in New York City, expiring
in April 2000. In addition, in March 2000, we entered into a lease for an
aggregate of approximately 83,500 square feet on two floors at a location in New
York City which we expect to occupy in the third quarter of 2000.

    We currently maintain offices in San Francisco subleased to us by one of our

                       OPTION GRANTS IN LAST FISCAL YEAR

    The following table sets forth information regarding exercisable and
unexercisable stock options granted to each of the named executive officers in
the last fiscal year. No stock appreciation rights were granted to the named
executive officers during the year ended December 31, 1999. Potential realizable
values are computed by (1) multiplying the number of shares of common stock
subject to a given option by the assumed market value on the date of grant,
(2) assuming that the aggregate stock value derived from that calculation
compounds annually for the entire term of the option and (3) subtracting from
that result the aggregate option exercise price.

(1) Each option represents the right to purchase one share of common stock.
    Mr. Bixby's 202,500 options which expire on June 23, 2009 vested 25% on
    January 1, 2000 and will vest an additional 25% on each anniversary thereof.
    Mr. Bixby's 97,500 options which expire on October 25, 2009 will vest 25% on
    July 1, 2000 and will vest an additional 25% on each anniversary thereof.
    Mr. Cohen's options will vest 50% on March 31, 2000 and 50% on March 31,
    2001.

(2) Amounts represent hypothetical gains that could be achieved for the
    respective options if exercised at the end of the option term. The 5% and
    10% assumed annual rates of compounded stock price appreciation are mandated
    by rules of the Securities and Exchange Commission and do not represent our
    estimate or projection of our future common stock prices. These amounts
    represent assumed rates of appreciation in the value of our common stock
    from the assumed fair market value on the date of grant. The assumed fair
    market values on the dates of grant relevant to this table were $0.72 per
    share for options granted between January 21, 1999 and May 3, 1999, $0.84
    per share for options granted between May 4, 1999 and July 18, 1999 and
    $2.22 per share for options granted between July 19, 1999 and October 25,
    1999. Actual gains, if any, on stock option exercises are dependent on the
    future performance of our common stock. The amounts reflected in the table
    may not necessarily be achieved. See "Risk Factors."

    The following table provides certain summary information concerning stock
options held as of December 31, 1999 by each of the named executive officers. No
options were exercised during fiscal 1999 by any of the named executive
officers. The value of the unexercised in-the-money options at December 31, 1999
is based on the assumed fair market value of our common stock at December 31,
1999, less the exercise price of the option, multiplied by the number of shares
underlying the options.

2000 STOCK INCENTIVE PLAN


    We adopted the 2000 Stock Incentive Plan (the "2000 Plan"), which will serve
as the successor equity incentive program to our Stock Option and Restricted
Stock Purchase Plan (the "1998 Plan"). The 2000 Plan became effective upon its
adoption by our board of directors on March 21, 2000 and will be ratified by our
stockholders prior to the date of this offering.


    10,000,000 shares of common stock have been authorized for issuance under
the 2000 Plan. This share reserve consists of the shares which were available
for issuance under the 1998 Plan on the effective date of the 2000 Plan plus an
additional increase of approximately 4,150,000 shares. The share reserve will
automatically be increased on the first trading day of January each calendar
year, beginning in January 2001, by a number of shares equal to 3% of the total
number of shares of common stock outstanding on the last trading day of the
immediately preceding calendar year, but no such annual increase will exceed
1,500,000 shares. However, in no event may any one participant in the 2000 Plan
receive option grants or direct stock issuances for more than 500,000 shares in
the aggregate per calendar year.

    Outstanding options under the 1998 Plan will be incorporated into the 2000
Plan upon the date of this offering, and no further option grants will be made
under that plan. The incorporated options will continue to be governed by their
existing terms, unless the compensation committee extends one or more features
of the 2000 Plan to those options. However, except as otherwise noted below, the
outstanding options under the 1998 Plan contain substantially the same terms and
conditions summarized below for the discretionary option grant program under the
2000 Plan.

    The 2000 Plan has five separate programs:

    -  the discretionary option grant program under which eligible individuals
       in our employ or service (including officers, non-employee board members
       and consultants) may be granted options to purchase shares of our common
       stock;

    -  the stock issuance program under which such individuals may be issued
       shares of common stock directly, through the purchase of such shares or
       as a bonus tied to the performance of services;

    -  the salary investment option grant program under which executive officers
       and other highly compensated employees may elect to apply a portion of
       their base salary to the acquisition of special below-market stock option
       grants;

    -  the automatic option grant program under which option grants will
       automatically be made at periodic intervals to eligible non-employee
       board members; and

    -  the director fee option grant program under which non-employee board
       members may elect to apply a portion of their retainer fee to the
       acquisition of special below-market stock option grants.

    The discretionary option grant and stock issuance programs will be
administered by our Compensation Committee. This committee will determine which
eligible individuals are to receive option grants or stock issuances, the time
or times when such option grants or stock issuances are to be made, the number
of shares subject to each such grant or issuance, the exercise or purchase price
for each such grant or issuance (which may be less than, equal to or greater
than the fair market value of the shares), the status of any granted option as
either an incentive stock option or a non-statutory stock option under the
federal tax laws, the vesting schedule to be in effect for the option grant or
stock issuance and the maximum term for which any granted option is to remain
outstanding. The committee will also select the executive officers and other
highly compensated employees who may participate in the salary investment option
grant program in

                                       59
<PAGE>
the event that program is activated for one or more calendar years. Neither the
Compensation Committee nor the board will exercise any administrative discretion
with respect to option grants made under the salary investment option grant
program or under the automatic option grant program or director fee option grant
program for the non-employee board members.

    The exercise price for the options may be paid in cash or in shares of our
common stock valued at fair market value on the exercise date. The option may
also be exercised through a same-day sale program without any cash outlay by the
optionee. In addition, the Compensation Committee may allow a participant to pay
the option exercise price or direct issue price (and any associated withholding
taxes incurred in connection with the acquisition of shares) with a
full-recourse, interest-bearing promissory note.

    In the event that we are acquired, whether by merger or asset sale or
board-approved sale by our stockholders of more than 50% of our voting stock,
each outstanding option under the discretionary option grant program which is
not to be assumed by the successor corporation or otherwise continued will
automatically accelerate in full, and all unvested shares under the
discretionary option grant and stock issuance programs will immediately vest,
except to the extent the repurchase rights with respect to those shares are to
be assigned to the successor corporation or otherwise continued in effect. The
Compensation Committee may grant options and issue shares which will accelerate
(i) in the acquisition even if the options are assumed and repurchase rights
assigned, (ii) in connection with a hostile change in control (effected through
a successful tender offer for more than 50% of our outstanding voting stock or
by proxy contest for the election of board members) or (iii) upon a termination
of the individual's service following a change in control or hostile takeover.

    In the event of an acquisition of our company (by merger or asset sale),
options currently outstanding under the 1998 Plan will be assumed by the
successor corporation. Such options are not by their terms subject to
acceleration in connection with any other change in control or hostile takeover.

    Stock appreciation rights may be issued under the discretionary option grant
program which will provide the holders with the election to surrender their
outstanding options for an appreciation distribution from us equal to the fair
market value of the vested shares subject to the surrendered option less the
aggregate exercise price payable for such shares. Such appreciation distribution
may be made in cash or in shares of common stock. There are currently no
outstanding stock appreciation rights under the 1998 Plan.


    The Compensation Committee has the authority to cancel outstanding options
under the discretionary option grant program (including options incorporated
from the 1998 Plan), with the consent of the holder, in return for the grant of
new options for the same or different number of option shares with an exercise
price per share based upon the fair market value of our common stock on the new
grant date.


    In the event our Compensation Committee elects to activate the salary
investment option grant program for one or more calendar years, each of our
executive officers and other highly compensated employees selected for
participation may elect to reduce his or her base salary for that calendar year
by a specified dollar amount not less than $5,000 nor more than $50,000. In
return, the individual will automatically be granted, on the first trading day
in the calendar year for which the salary reduction is to be in effect, a
non-statutory option to purchase that number of shares of common stock
determined by dividing the salary reduction amount by two-thirds of the fair
market value per share of our common stock on the grant date. The option
exercise price will be equal to one-third of the fair market value of the option
shares on the grant date. As a result, the fair market value of the option
shares on the grant date less the exercise price payable for those shares will
be equal to the salary reduction amount. The option will become exercisable

                                       60
<PAGE>
in a series of 12 equal monthly installments over the calendar year for which
the salary reduction is to be in effect and will be subject to full and
immediate vesting in the event of an acquisition or change in control of the
company.

    Under the automatic option grant program, each individual who first joins
the board after the date of this offering as a non-employee board member will
automatically be granted an option for 15,000 shares of our common stock at the
time of his or her commencement of board service, provided such individual has
not been in our prior employ. In addition, on the date of each of our annual
stockholders' meeting held after the date of this offering, each individual who
is to continue to serve as a non-employee board member after such meeting will
receive an option grant to purchase 5,000 shares of common stock. Each automatic
grant will have an exercise price equal to the fair market value per share of
our common stock on the grant date and will have a maximum term of 10 years,
subject to earlier termination following the optionee's cessation of board
service. Each option will be immediately exercisable, subject to our right to
repurchase any unvested shares, at the original exercise price, at the time of
the board member's cessation of service. Each 15,000-share option grant will
vest, and the repurchase right will lapse, in a series of three equal successive
annual installments upon the optionee's completion of each year of board service
over the three-year period measured from the grant date. Each 5,000-share option
grant will vest, and the repurchase right will lapse, upon the optionee's
completion of one year of board service measured from the grant date. However,
each such outstanding option will immediately vest upon a change in control, a
hostile takeover or the death or disability of the optionee while serving as a
board member.

    If the director fee option grant program is put into effect in the future,
then each non-employee board member may elect to apply all or a portion of any
cash retainer fee for the year to the acquisition of a below-market option
grant. The option grant will automatically be made on the first trading day in
January in the year for which the non-employee board member would otherwise be
paid the cash retainer fee in the absence of his or her election. The option
will have an exercise price per share equal to one-third of the fair market
value of the option shares on the grant date, and the number of shares subject
to the option will be determined by dividing the amount of the retainer fee
applied to the program by two-thirds of the fair market value per share of
common stock on the grant date. As a result, the fair market value of the option
shares on the grant date less the exercise price payable for those shares will
be equal to the portion of the retainer fee applied to that option. The option
will become exercisable in a series of 12 equal monthly installments over the
calendar year for which the election is in effect. However, the option will
become immediately exercisable for all the option shares upon the death or
disability of the optionee while serving as a board member.

    Limited stock appreciation rights will automatically be included as part of
each grant made under the automatic option grant and salary investment option
grant programs and may be granted to one or more officers as part of their
option grants under the discretionary option grant program. Options with such a
limited stock appreciation right may be surrendered to the company upon the
successful completion of a hostile tender offer for more than 50% of our
outstanding voting stock. In return for the surrendered option, the optionee
will be entitled to a cash distribution from us in an amount per surrendered
option share equal to the highest price per share of common stock paid in
connection with the tender offer less the exercise price payable for such share.


    The board may amend or modify the 2000 Plan at any time, subject to any
required stockholder approval. The 2000 Plan will terminate no later than
March 21, 2010.


                                       61

EMPLOYEE STOCK PURCHASE PLAN


    We adopted the Employee Stock Purchase Plan (the "ESPP"), which is intended
to serve (along with the 2000 Plan) as the successor program to the 1998 Plan.
The ESPP was adopted by our board of directors on March 21, 2000 and will be
ratified by our stockholders prior to the date of this offering. The ESPP will
become effective immediately upon the execution of the underwriting agreement
for this offering. The ESPP is designed to allow our eligible employees and
eligible employees of our participating subsidiaries, if any, to purchase shares
of common stock, at semi-annual intervals, through their periodic payroll
deductions. Up to 450,000 shares of our common stock will initially be issued
under the ESPP. The share reserve will automatically increase on the first
trading day of January of each year beginning in January 2001, by 0.50% of the
total shares of common stock outstanding on the last trading day of the
immediately preceding calendar year, but no such annual increase will exceed
150,000 shares. In no event, however, may any participant purchase more than
1,000 shares, nor may all participants in the aggregate purchase more than
112,500 shares on any one semi-annual purchase date.


    The ESPP will have a series of successive offering periods, each with a
maximum duration of 24 months. However, the initial offering period will begin
on the day the underwriting agreement is executed in connection with this
offering and will end on the last business day in April 2002. The next offering
period will begin on the first business day in May 2002, and subsequent offering
periods will be set by the Compensation Committee. Shares will be purchased for
the participants semi-annually (the last business day of October and April each
year) during the offering period. The first purchase date will occur on
October 31, 2000. Should the fair market value of the common stock on any
semi-annual purchase date be less than the fair market value on the first day of
the offering period, then the current offering period will automatically end and
a new offering period will begin, based on the lower fair market value.

    Individuals who are eligible employees on the start date of any offering
period may enter the ESPP on that start date or on any subsequent semi-annual
entry date (generally May 1 or November 1 of each year). Individuals who become
eligible employees after the start date of the offering period may join the ESPP
on any subsequent semi-annual entry date within that period.

    A participant may contribute up to 15% of his or her cash compensation
through payroll deductions and the accumulated payroll deductions will be
applied to the purchase of shares on the participant's behalf on each
semi-annual purchase date. The purchase price per share will be 85% of the lower
of the fair market value of our common stock on the participant's entry date
into the offering period or the fair market value on the semi-annual purchase
date.


    The board may at any time amend or modify the ESPP. The ESPP will terminate
no later than March 21, 2010.

              CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

PREFERRED STOCK INVESTMENTS

    We issued 2,541,667 shares of series A convertible preferred stock in
January 1999; 1,142,857 shares of series B convertible preferred stock in
May 1999; 5,132,433 shares of series C redeemable convertible preferred stock in
July 1999 and 3,157,895 shares of series D redeemable convertible preferred
stock in January 2000. Substantially all of our shares of convertible preferred
stock have been sold to venture capital funds. The detailed description of the
beneficial ownership within each venture capital fund, and cumulative ownership
information for entities that hold a 5% or more beneficial interest, is
contained in "Principal Stockholders," and the footnotes thereto, to the extent
not described below. Each share of convertible preferred stock will
automatically convert into common stock upon closing of this offering at a
two-for-three ratio.

    SERIES A CONVERTIBLE PREFERRED STOCK.  We sold 2,500,000 shares of series A
convertible preferred stock in January 1999 at a purchase price per share of
$1.20 for gross proceeds of $3,000,000. In these transactions, we sold:

    -  937,500 shares to Dawntreader Fund I LP;

    -  937,500 shares to FG-LP, an entity affiliated with FGII;

    -  416,667 shares to Sterling Payot Capital, LP; and

    -  208,333 shares to an affiliate of Silicon Alley Venture Partners, LLC.

A portion of the series A convertible preferred stock issued to FG-LP was issued
in satisfaction of a promissory note made by us in the amount of $100,000, plus
interest. In addition, we issued 41,667 shares to Silicon Alley Venture
Partners, LLC in exchange for consulting services related to the sale of the
series A convertible preferred stock.

    We also issued warrants to these investors at an exercise price of $1.60 per
share. These warrants have a purchase price of $0.003 per warrant, expire in
January 2004 and are exercisable at any time. The expiration date of the
warrants may be accelerated in certain circumstances, if the managing
underwriter of this offering determines that the failure to accelerate the
expiration or exercise of the warrant could adversely affect this offering;
however, we have been informed by Chase Securities Inc. that they do not intend
to do so. These warrants are exercisable for:

    -  175,781 shares by Dawntreader Fund I LP;

    -  175,781 shares by FG-LP;

    -  78,124 shares by Sterling Payot Capital, LP; and

adversely affect this offering; however, we have been informed by Chase

stock, which vested on July 1, 1999, to Kevin Lavan, a director, for advisory
services rendered prior to his appointment to our board of directors. In

SAN FRANCISCO LEASE

    Since August 1999, we have leased our San Francisco office space pursuant to
a month-to-month agreement with Sterling Payot Capital, LP, one of our
investors. Our monthly payments for rent and shared services are approximately
$11,000 and, to date, we have paid an aggregate of

                                       64
<PAGE>
approximately $82,500 under the lease. We believe that this lease is on terms no
less favorable to us than could be obtained from unaffiliated third parties. We
expect to terminate this agreement upon relocation into our new San Francisco
offices, which is expected to occur in the second quarter of 2000.

CHIEF OPERATING OFFICER CONSULTING SERVICES

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

    The following description of our common stock and preferred stock and the
relevant provisions of our amended and restated certificate of incorporation and
amended and restated bylaws to be in effect upon the closing of this offering
are summaries thereof and are qualified by reference to our amended and restated
certificate of incorporation and amended and restated bylaws, copies of which
have been filed with the Securities and Exchange Commission as exhibits to our
registration statement, of which this prospectus forms a part.

    Upon the closing of our offering, our authorized capital stock will consist
of 100,000,000 shares of common stock, par value $0.001 per share, and 5,000,000
shares of preferred stock, par value $0.001 per share.

COMMON STOCK

    As of March 8, 2000, there were 7,361,531 shares of our common stock
outstanding held of record by seven stockholders, without giving effect to the
conversion of our convertible preferred stock. Holders of common stock are
entitled to one vote for each share held on all matters submitted to a vote of
stockholders and do not have cumulative voting rights. Accordingly, holders of a
majority of the shares of common stock entitled to vote in any election of
directors may elect all of the directors standing for election. Holders of
common stock are entitled to receive ratably those dividends, if any, as may be
declared by our board of directors out of funds legally available therefor,
subject to any preferential dividend rights of any outstanding preferred stock.
Upon our liquidation, dissolution or winding up, our common stockholders are
entitled to receive ratably our net assets available, if any, after the payment
of all debts and other liabilities and subject to the prior rights of any
outstanding preferred stock. Holders of our common stock have no preemptive,
subscription, redemption or conversion rights. The outstanding shares of our
common stock are, and the shares offered in this offering will be, when issued
in consideration for payment thereof, fully paid and nonassessable. The rights,
preferences and privileges of holders of common stock are subject to, and may be
adversely affected by, the rights of the holders of shares of any series of
preferred stock which we may designate and issue in the future.

PREFERRED STOCK

    Upon the closing of this offering, there will be no shares of preferred
stock outstanding. Our board of directors will be authorized, without further
stockholder approval, to issue from time to time up to an aggregate of 5,000,000
shares of preferred stock in one or more series and to fix or alter the
designations, preferences, rights and any qualifications, limitations or
restrictions of the shares of each series thereof, including the dividend
rights, dividend rates, conversion rights, voting rights, terms of redemption,
including sinking fund provisions, redemption price or prices, liquidation
preferences and the number of shares constituting any series or designation of
series. The issuance of preferred stock could decrease the amount of earnings
and assets available for distribution to holders of common stock or adversely
affect the rights and powers, including voting rights, of the holders of common
stock. Such issuance could also have the effect of delaying, deferring or
preventing a change in control of our company. For more information, see
"--Anti-Takeover Effects of Provisions of Delaware Law and Our Certificate of
Incorporation and Bylaws."

OPTIONS

    We have 10,000,000 shares of our common stock reserved for issuance, upon
exercise of stock options, under our 2000 Stock Incentive Plan. As of March 8,
2000, there were outstanding

                                       69
<PAGE>
options to purchase a total of 5,528,970 shares of common stock, of which
options to purchase approximately 1,467,853 will be exercisable upon the closing
of this offering. Because we intend to file a registration statement on
Form S-8 as soon as practicable following the closing of this offering, any
shares issued upon exercise of these options will be immediately available for
sale in the public market, subject to the terms of lock-up agreements entered
into with the underwriters. For more information, see "Management--2000 Stock
Incentive Plan" and "Shares Eligible for Future Sale." We also have 94,500
shares of our common stock reserved for issuance, upon exercise of an option
granted to a client. For more information, please see "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Overview."

REGISTRATION RIGHTS

    Pursuant to the terms of a registration rights agreement, beginning 180 days
after the effective date of the Registration Statement of which this prospectus
is a part, the holders of 25,824,772 shares of common stock and warrants to
acquire common stock have the right to demand registration of their shares of
common stock under the Securities Act of 1933. We are not required to effect
more than two registrations pursuant to these demand registration rights (unless
we are eligible to file a registration statement on Form S-3, in which case we
may be required to effect up to three registrations). In addition, these holders
are entitled, subject to limitations, to require us to register the common stock
held by them when we register common stock for our own account or for the
account of other stockholders. This type of registration right is known as a
"piggyback" registration right. These registration rights are subject to certain
conditions and limitations, among them the right of the underwriters of an
offering to limit the number of shares of common stock held by stockholders with
registration rights to be included in a registration. Generally, we are required
to bear all of the expenses of all of these registrations, except underwriting
discounts and selling commissions. Registration of any shares of common stock
held by security holders with registration rights would result in shares
becoming freely tradable without restriction under the Securities Act of 1933
immediately upon effectiveness of such registration.

LIMITATIONS ON LIABILITY

    Our amended and restated certificate of incorporation limits or eliminates
the liability of our directors to us or our stockholders for monetary damage to
the fullest extent permitted by the Delaware General Corporation Law. As
permitted by the Delaware General Corporation Law, our amended and restated
certificate of incorporation provides that our directors shall not be personally
liable to us or our stockholders for monetary damages for a breach of fiduciary
duty as a director, except for liability:

    -  for any breach of such person's duty of loyalty to us or our
       stockholders;

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

    -  for payment of dividends or approval of stock repurchases or redemptions
       that are prohibited by Section 174 of the Delaware General Corporation
       Law; and

    -  for any transaction resulting in receipt by such person of an improper
       personal benefit.

    Our amended and restated certificate of incorporation also contains
provisions indemnifying our directors and officers to the fullest extent
permitted by the Delaware General Corporation Law. We currently have directors'
and officers' liability insurance to provide our directors and officers with
insurance coverage for losses arising from claims based on breaches of duty,
negligence, errors and other wrongful acts.

                                       70
<PAGE>
    We have also entered into agreements to indemnify our directors and
executive officers, in addition to the indemnification provided for in our
amended and restated certificate of incorporation. We believe that these
agreements are necessary to attract and retain qualified directors and executive
officers.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF DELAWARE LAW AND OUR CERTIFICATE OF
    INCORPORATION AND BYLAWS

    We are subject to the provisions of Section 203 of the Delaware General
Corporation Law. Subject to some exceptions, Section 203 prohibits a
publicly-held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years after the date of
the transaction in which the person became an interested stockholder, unless:

    -  prior to such date, the board of directors of the corporation approved
       either the business combination or the transaction that resulted in the
       stockholder becoming an interested stockholder;

    -  upon consummation of the transaction that resulted in the stockholder
       becoming an interested stockholder, the interested stockholder owned at
       least 85% of the voting stock of the corporation outstanding at the time
       the transaction commenced (excluding certain shares); or

    -  on or subsequent to such date, the business combination is approved by
       the board of directors of the corporation and authorized at an annual or
       special meeting of stockholders by the affirmative vote of a least 66.67%
       of the outstanding voting stock that is not owned by the interested
       stockholder.

A "business combination" includes mergers, asset sales and other transactions
resulting in a financial benefit to the interested stockholder. Except as
otherwise specified in Section 203 of the Delaware General Corporation Law, an
interested stockholder is defined to include (x) any person that owns (or,
within the prior three years, did own) 15% or more of the outstanding voting
stock of the corporation, or is an affiliate or associate of the corporation and
was the owner of 15% or more of the outstanding voting stock of the corporation
at any time within three years immediately prior to the date of determination
and (y) the affiliates and associates of any such person. This statute could
prohibit or delay the accomplishment of mergers or other takeover or change in
control attempts with respect to us and, accordingly, may discourage attempts to
acquire us.

    In addition, various provisions of our amended and restated certificate of
incorporation and our amended and restated bylaws, which provisions will be in
effect upon the closing of the offering and are summarized in the following
paragraphs, may be deemed to have an anti-takeover effect and may delay, defer
or prevent a tender offer or takeover attempt that a stockholder might consider
in its best interest, including those attempts that might result in a premium
over the market price for the shares held by stockholders.

    STAGGERED BOARD.  Our amended and restated certificate of incorporation
provides for division of our board into three classes, with each class as nearly
equal in number as possible. Each class must serve a three-year term. The terms
of each class are staggered so that each term ends in a different year in the
three-year period.

    BOARD OF DIRECTORS VACANCIES.  Our amended and restated certificate of
incorporation authorizes our board of directors to fill vacant directorships or
increase the size of the board of directors. This may deter a stockholder from
removing incumbent directors and simultaneously

                                       71
<PAGE>
gaining control of our board of directors by filling the vacancies created by
this removal with its own nominees.

    STOCKHOLDER ACTION; SPECIAL MEETING OF STOCKHOLDERS.  Our amended and
restated certificate of incorporation provides that stockholders may not take
action by written consent, but only at duly called annual or special meetings of
stockholders. Our amended and restated bylaws further provide that special
meetings of our stockholders may be called only by the chairman of the board of
directors, our president or at the request of two-thirds of the board of
directors.

    ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTORS'
NOMINATIONS. Our amended and restated bylaws provide that stockholders seeking
to bring business before an annual meeting of stockholders, or to nominate
candidates for election as directors at an annual meeting of stockholders, must
provide us timely notice thereof in writing. To be timely, a stockholder's
notice must be delivered to or mailed and received at our principal executive
offices, not less than 90 days nor more than 120 days prior to the first
anniversary of the date of the preceding year's annual meeting provided with
respect to the previous year's annual meeting of stockholders; provided,
however, that if no annual meeting of stockholders was held in the previous year
or the date of the annual meeting of stockholders has been changed to be more
than 30 calendar days earlier than or 70 calendar days after this anniversary,
notice by the stockholder, to be timely, must be so received not more than
120 days prior to the annual meeting of stockholders nor later than the later
of:

    -  90 days prior to the annual meeting of stockholders; and

    -  the close of business on the 10th day following the date on which notice
       of the date of the meeting is made public.

    Our amended and restated bylaws also specify certain requirements as to the
form and content of a stockholders' notice. These provisions may preclude
stockholders from bringing matters before an annual meeting of stockholders or
from making nominations for directors at an annual meeting of stockholders.

    AUTHORIZED BUT UNISSUED SHARES.  The authorized but unissued shares of our
common stock and preferred stock are available for future issuance without
stockholder approval, subject to various limitations imposed by the Nasdaq
National Market. These additional shares may be utilized for a variety of
corporate purposes, including future public offerings to raise additional
capital, corporate acquisitions and employee benefit plans. The existence of
authorized but unissued shares of common stock and preferred stock could make
more difficult or discourage an attempt to obtain control of us by means of a
proxy context, tender offer, merger or otherwise.

    Our amended and restated certificate of incorporation requires the
affirmative vote of not less than 66.67% of the outstanding shares of our
capital stock entitled to vote generally in the election of directors
(considered for this purpose as a single class) cast at a meeting of our
stockholders called for that purpose, to repeal, alter, amend or rescind the
provisions in our amended and restated certificate of incorporation relating to:

    -  directors;

    -  stockholder meetings;

    -  limitations on director liability;

    -  indemnification;

    -  amendment of our bylaws; or

    -  business combinations.

                                       72

    Our amended and restated certificate of incorporation requires the
affirmative vote as specified in the Delaware General Corporation Law to amend
any other provision of our amended and restated certificate of incorporation.


    To repeal, alter, amend or rescind our amended and restated bylaws, our
amended and restated certificate incorporation and our amended and restated
bylaws require the affirmative vote of not less than 66.67% of the outstanding
shares of our capital stock entitled to vote generally in the election of
directors (considered for this purpose as a single class) cast at a meeting of
our stockholders called for that purpose, or the affirmative vote of at least
66.67% of our board of directors. This provision may have the effect of making
it difficult for a third party to acquire us.


TRANSFER AGENT AND REGISTRAR

    The transfer agent and registrar for our common stock is American Stock
Transfer & Trust Company.

                        SHARES ELIGIBLE FOR FUTURE SALE

    Sales of substantial amounts of our common stock in the public market could
adversely affect prevailing market prices of our common stock. Furthermore,
since substantially all outstanding shares of our common stock (other than those
shares offered in this offering) will not be available for sale shortly after
this offering because of certain contractual and legal restrictions on resale
described below, sales of substantial amounts of common stock in the public
market after these restrictions lapse could adversely affect the prevailing
market price and our ability to raise equity capital in the future.


    Upon the closing of this offering, we will have outstanding an aggregate of
29,323,804 shares of our common stock, assuming no exercise of the underwriters'
over-allotment option and no exercise of outstanding options. Of these shares,
all shares sold in this offering will be freely tradable without restriction or
further registration under the Securities Act of 1933 unless such shares are
purchased by "affiliates" as that term is defined in Rule 144 under the
Securities Act of 1933. Unless sold earlier pursuant to a registered public
offering, the remaining 25,323,804 shares of common stock held by existing
stockholders are "restricted securities" as defined in Rule 144. Restricted
securities may be sold in the public market only if registered or if they
qualify for an exemption from registration under Rule 144, Rule 144(k) or 701
under the Securities Act of 1933, which rules are summarized below. The
following table illustrates the shares eligible for sale in the public market:

    LOCK-UP AGREEMENTS


    Our directors, executive officers, and substantially all of our existing
stockholders and optionholders have signed lock-up agreements under which they
have agreed that, without the prior written consent of Chase Securities Inc. on

    -  enter into any swap or other arrangement that transfers to another, in
       whole or in part, any of the economic consequences of ownership of the
       common stock;

                                       74
<PAGE>
whether any transaction described above is to be settled by delivery of common
stock or such other securities, in cash or otherwise.

    The restrictions described in the preceding paragraph do not apply to:

    -  transfers to certain persons or entities of shares of our common stock or
       any securities convertible into or exercisable or exchangeable for our
       common stock, provided that the transferees agree in writing to be bound
       by the foregoing restrictions;

    -  non-derivative sales in open market transactions of shares of our common
       stock or other securities acquired in open market transactions after the
       completion of the offering of the shares; and

    -  non-derivative sales in open market transactions of shares of our common
       stock reserved by the underwriters for, and sold at the initial public
       offering price to, our directors, employees other than executive
       officers, business associates, and their family members.


    Chase Securities Inc. may waive the restrictions imposed by the lock-up
agreements at any time.


    RULE 144

    In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
common stock for at least one year would be entitled to sell within any
three-month period a number of shares that does not exceed the greater of
(i) 1% of the number of shares of common stock then outstanding, which will
equal approximately 293,238 shares immediately after the offering, and (ii) the
average weekly trading volume of the common stock on the Nasdaq National Market
during the four calendar weeks preceding the filing of a notice on Form 144 with
respect to such sale. Sales under Rule 144 are also subject to certain
manner-of-sale provisions, notice requirements and the availability of current
public information about us.

    RULE 144(K)

    Under Rule 144(k), a person who is not one of our affiliates at any time
during the 90 days preceding a sale and who has beneficially owned the shares
proposed to be sold for at least two years, including the holding period of any
prior owner other than an affiliate, is entitled to sell such shares without
complying with the manner of sale, public information, volume limitation or
notice provisions of Rule 144. Therefore, unless otherwise contractually
restricted, "144(k)" shares may be sold immediately upon completion of this
offering.

    RULE 701

    In general, under Rule 701 of the Securities Act of 1933 as currently in
effect, each of our employees, consultants or advisors who purchases shares from
us in connection with a compensatory stock plan or other written agreement is
eligible to resell such shares 90 days after the date of this prospectus in
reliance on Rule 144, but without compliance with certain restrictions,
including the holding period, contained in Rule 144.

    REGISTRATION RIGHTS

    After this offering, the holders of 25,824,772 shares of our common stock
and warrants to acquire common stock will be entitled to certain rights with
respect to the registration of those shares under the Securities Act of 1933.
For more information, see "Description of Capital Stock--Registration Rights."
After such registration, these shares of our common stock become

                                       75
<PAGE>
freely tradable without restriction under the Securities Act. These sales could
have a material adverse effect on the trading price of our common stock.

    STOCK PLANS AND OTHER OPTIONS

    Immediately after this offering, we intend to file a registration statement
under the Securities Act covering 10,450,000 shares of common stock reserved for
issuance under our
2000 Stock Incentive Plan and our Employee Stock Purchase Plan. We expect this
registration statement to be filed and to become effective as soon as
practicable after the effective date of this offering.

    As of March 8, 2000, options to purchase 5,528,970 shares of common stock
were issued and outstanding under our 2000 Plan, of which 1,472,753 are
exercisable within 60 days of March 8, 2000. Upon exercise, the shares
underlying these options will be eligible for sale in the public market from
time to time, subject to vesting provisions, Rule 144 volume limitations
applicable to our affiliates and, in the case of some options, the expiration of
lock-up agreements. In addition, an option to purchase 94,500 shares of common
stock was issued and outstanding outside of our 2000 Plan, which is currently
fully vested and immediately exercisable; however the sale of the shares of
common stock underlying this option is subject to restrictions described in
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Overview--Compensation."

</TABLE>

    DISCOUNTS AND COMMISSIONS.  The underwriting agreement provides that the
obligations of the underwriters are subject to certain conditions precedent,
including the absence of any material adverse change in our business and the
receipt of certain certificates, opinions and letters from us, our counsel and
the independent auditors. The underwriters are committed to purchase all of the
shares of common stock offered by us if they purchase any shares.

    The following table shows the per share and total underwriting discounts and
commissions we will pay to the underwriters. The underwriting discounts and
commissions were determined through negotiations with the underwriters, and
equal the public offering price per share of common stock, less the amount paid
by the underwriters to us per share of common stock. Such amounts are shown
assuming both no exercise and full exercise of the underwriters' over-allotment
option to purchase additional shares.

</TABLE>

    We estimate that the total expenses of this offering, excluding underwriting
discounts and commissions, will be approximately $1,000,000.

    The underwriters propose to offer the shares of common stock directly to the
public at the initial public offering price set forth on the cover page of this
prospectus and to certain dealers at that price less a concession not in excess
of $           per share. The underwriters may allow and such dealers may
reallow a concession not in excess of $           per share to certain other
dealers. After the initial public offering of the shares, the offering price and
other selling terms may be changed by the representatives of the underwriters.
The representatives have advised us that the underwriters do not intend to
confirm discretionary sales in excess of 5% of the shares of common stock
offered by this prospectus.

    OVER-ALLOTMENT OPTION.  We have granted to the underwriters an option,
exercisable no later than 30 days after the date of this prospectus, to purchase
up to 600,000 additional shares of common stock at the initial public offering
price, less the underwriting discount set forth on the cover page of this
prospectus. To the extent that the underwriters exercise this option, each of

                                       77
<PAGE>
the underwriters will have a firm commitment to purchase approximately the same
percentage thereof which the number of shares of common stock to be purchased by
it shown in the above table bears to the total number of shares of common stock
offered hereby. We will be obligated, pursuant to the option, to sell shares to
the underwriters to the extent the option is exercised. The underwriters may
exercise this option only to cover over-allotments made in connection with the
sale of shares of common stock offered by us.

    DELIVERY OF SHARES.  The offering of the shares is made for delivery when,
as and if accepted by the underwriters and subject to prior sale and to
withdrawal, cancellation or modification of the offering without notice. The
underwriters reserve the right to reject an order for the purchase of shares in
whole or in part.

    INDEMNIFICATION.  We have agreed to indemnify the underwriters against
certain liabilities, including liabilities under the Securities Act of 1933, and
to contribute to payments the underwriters may be required to make in respect of
these liabilities.


    LOCK-UP AGREEMENTS.  We and our directors, executive officers and
substantially all of our existing stockholders and optionholders have agreed
that, without the prior written consent of Chase Securities Inc. on behalf of
the underwriters, we and they will not, during the period ending 180 days after
the date of this prospectus:


    -  offer, pledge, sell, contract to sell, sell any option or contract to
       purchase, purchase any option or contract to sell, grant any option,
       right or warrant to purchase, lend or otherwise transfer or dispose of
       directly or indirectly, any shares of common stock or any securities
       convertible into or exercisable or exchangeable for common stock; or

    -  enter into any swap or other arrangement that transfers to another, in
       whole or in part, any of the economic consequences of ownership of the
       common stock;

whether any transaction described above is to be settled by delivery of common
stock or such other securities, in cash or otherwise.

    The restrictions described in this paragraph do not apply to:

    -  the sale of shares to the underwriters;

    -  the issuance of shares of our common stock upon the exercise of an option
       or a warrant, or the conversion of a security outstanding on the date of
       this prospectus of which the underwriters have been advised in writing;

    -  the grant of additional options under our 2000 Plan and our ESPP;

    -  transfers to certain persons or entities of shares of our common stock or
       any securities convertible into or exercisable or exchangeable for our
       common stock, provided that the transferees agree in writing to be bound
       by the foregoing restrictions;

    -  non-derivative sales in open market transactions by any person other than
       us relating to shares of our common stock or other securities acquired in
       open market transactions after the completion of the offering of the
       shares; and

    -  non-derivative sales in open market transactions of shares of our common
       stock reserved by the underwriters for, and sold at the initial public
       offering price to, our directors, employees other than executive
       officers, business associates, and their family members.

    Without the prior written consent of Chase Securities Inc., any options
granted outside of our 2000 Plan shall not be exercisable during this 180-day
period. In addition, if Chase Securities Inc. agrees to release any of our
stockholders (except any employee or consultant that is not one

                                       78
<PAGE>
of our officers or directors) from the foregoing restrictions prior to the
expiration of the 180-day period referred to above, with respect to all or a
percentage of the shares of our common stock or any securities convertible into
or exercisable or exchangeable for our common stock subject to the foregoing
restrictions, then all of our other stockholders subject to the foregoing
restrictions shall be released from such restrictions to the same extent and on
the same terms and conditions.

    STABILIZATION.  Certain persons participating in this offering may
over-allot or effect transactions which stabilize, maintain or otherwise affect
the market price of the common stock at levels above those which might otherwise
prevail in the open market, including by entering stabilizing bids, effecting
syndicate covering transactions or imposing penalty bids. A stabilizing bid
means the placing of any bid or effecting of any purchase, for the purpose of
pegging, fixing or maintaining the price of the common stock. A syndicate
covering transaction means the placing of any bid on behalf of the underwriting
syndicate or the effecting of any purchase to reduce a short position created in
connection with the offering. A penalty bid means an arrangement that permits
the underwriters to reclaim a selling concession from a syndicate member in
connection with the offering when shares of common stock sold by the syndicate
member are purchased in syndicate covering transactions. Such transactions may
be effected on the Nasdaq National Market, in the over-the-counter market, or
otherwise. Such stabilizing, if commenced, may be discontinued at any time.

    DETERMINATION OF OFFERING PRICE.  Prior to this offering, there has been no
public market for our common stock. The initial public offering price for the
common stock will be determined by negotiations among us and the
representatives. Among the factors to be considered in determining the initial
public offering price will be prevailing market and economic conditions, our
revenue and earnings, market valuations of other companies engaged in activities
similar to our business operations, and our management. The estimated initial
public offering price range set forth on the cover of this preliminary
prospectus is subject to change as a result of market conditions or other
factors.

    RESERVED SHARES.  At our request, the underwriters have reserved up to
400,000 shares of common stock for sale at the initial public offering price to
our directors, officers, employees, business associates, and their family
members. The number of shares of common stock available for sale to the general
public will be reduced if such persons purchase the reserved shares. Any
reserved shares which are not so purchased will be offered by the underwriters
to the general public on the same basis as the other shares offered hereby.

    UNDERWRITER'S BENEFICIAL OWNERSHIP.  Chase Securities Inc. may be deemed to
have beneficial ownership of an aggregate of 108,108 shares of our series C
redeemable convertible preferred stock. Additionally, Access Technology
Partners, L.P., a fund of outside investors that is managed by an affiliate of
Chase Securities Inc., owns 432,432 shares of our series C redeemable
convertible preferred stock. All shares of convertible preferred stock issued by
us, including the series C redeemable convertible preferred stock, will
automatically convert into shares of common stock upon completion of this
offering, at a two-for-three ratio. Upon such conversion, Chase Securities Inc.
may be deemed to have beneficial ownership of 0.6% of the shares of common stock
outstanding.

    NEW UNDERWRITER.  Thomas Weisel Partners LLC, one of the representatives of
the underwriters, was organized and registered as a broker-dealer in
December 1998. Since December 1998, Thomas Weisel Partners has been named as a
lead or co-manager of 131 filed public offerings of equity securities, of which
99 have been completed, and has acted as a syndicate member in an additional 69

material relationship with us or any of our officers, directors or controlling
persons, except with respect to its contractual relationship with us under the

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of
  LivePerson, Inc.:

    We have audited the accompanying balance sheets of LivePerson, Inc. as of
December 31, 1998 and 1999, and the related statements of operations,
stockholders' deficit, and cash flows for each of the years in the three-year
period ended December 31, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of LivePerson, Inc. as of
December 31, 1998 and 1999, and the results of its operations and its cash flows
for each of the years in the three-year period ended December 31, 1999 in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

                           DECEMBER 31, 1998 AND 1999

         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1999 IS UNAUDITED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

(1) SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

    (A) SUMMARY OF OPERATIONS

    LivePerson, Inc. (the "Company" or "LivePerson"), was incorporated in the
State of Delaware in 1995 under the name of Sybarite Interactive, Inc. The
Company, which commenced operations in 1996, changed its name to Live Person,
Inc. in January 1999 and to LivePerson, Inc. in March 2000. The Company offers
the LivePerson service, which facilitates real-time sales and customer service
for companies doing business on the Internet.

    The Company generates revenues from the sale of the LivePerson service.
Prior to November 1998, when the LivePerson service was introduced, the Company
provided services primarily related to Web-based community programming and media
design.


    (B) USE OF ESTIMATES


    The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
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.


    (C) CASH AND CASH EQUIVALENTS


    The Company considers all highly liquid securities, with original maturities
of three months or less when acquired, to be cash equivalents.


    (D) PROPERTY AND EQUIPMENT


    Property and equipment are stated at cost less accumulated depreciation.
Depreciation is calculated using the straight-line method over the estimated
useful lives of the related assets, generally ranging from three to seven years.


    (E) IMPAIRMENT OF LONG-LIVED ASSETS


    The Company reviews its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of the assets to future net cash flows
expected to be generated by the assets. If the assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the fair value of the assets. To date, no
impairment has occurred.


    (F) INCOME TAXES


    Income taxes are accounted for under the asset and liability method. Under
this method, deferred tax assets and liabilities are recognized for the future
tax consequences attributable to

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                           DECEMBER 31, 1998 AND 1999

         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1999 IS UNAUDITED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

(1) SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases and operating loss and tax credit
carryforwards. Deferred tax assets and liabilities are measured using enacted
tax rates expected to apply to taxable income in the years in which those
temporary differences are expected to be recovered or settled. The effect on
deferred tax assets and liabilities of a change in tax rates is recognized in
results of operations in the period that the tax change occurs. Valuation
allowances are established, when necessary, to reduce deferred tax assets to the
amount expected to be realized.


    (G) REVENUE RECOGNITION


    Prior to November 1998, when the LivePerson service was introduced, the
Company generated revenue from services primarily related to Web-based community
programming and media design. Revenues from such services are recognized upon
completion of the project provided that no significant Company obligations
remain and collection of the resulting receivable is probable.

    During 1998, the Company began offering the LivePerson service. The
LivePerson service facilitates real-time sales and customer service for
companies doing business on the Internet. The Company charges an initial
non-refundable set-up fee as well as a monthly fee for each operator access
account ("seat") using the LivePerson service.

    The initial set-up fee principally represents customer service, training and
other administrative costs related to the deployment of the LivePerson service.
Such fees are recorded as deferred revenue and recognized over a period of
24 months, representing the Company's current estimate of the expected term of a
client relationship. This estimate may change in the future.

    The Company also records revenue based upon a monthly fee charged for each
seat using the LivePerson service provided that no significant Company
obligations remain and collection of the resulting receivable is probable. The
Company recognizes monthly service revenue fees as services are provided. The
Company's service agreements typically have no termination date and are
terminable by either party upon 30 to 90 days' notice without penalty. The
Company does not charge an additional set-up fee if an existing client adds more
seats.


    (H) PRODUCT DEVELOPMENT COSTS


    The Company accounts for product development costs in accordance with SFAS
No. 86, "Accounting for the Costs of Computer Software to be Sold, Leased, or
Otherwise Marketed," under which certain software development costs incurred
subsequent to the establishment of technological feasibility are capitalized and
amortized over the estimated lives of the related products. Technological
feasibility is established upon completion of a working model. To date,
completion of a working model of the Company's products and general release have
substantially coincided. As a result, the Company has not capitalized any
software development costs since

                           DECEMBER 31, 1998 AND 1999

         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1999 IS UNAUDITED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

(1) SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
such costs have not been significant. Through December 31, 1999, all development
costs have been charged to product development expense in the accompanying
statements of operations.


    (I) ADVERTISING COSTS


    The Company expenses the cost of advertising and promoting its services as
incurred. Such costs totaled approximately $0, $1 and $1,935 for the years
ending December 31, 1997, 1998 and 1999, respectively.


    (J) FINANCIAL INSTRUMENTS AND CONCENTRATION OF CREDIT RISK


    Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist of cash and cash equivalents, accounts
receivable, accounts payable and note payable. At December 31, 1998 and 1999,
the fair value of these instruments approximated their financial statement
carrying amount because of the short-term maturity of these instruments. The
Company has not experienced any significant credit loss to date. In 1997, two
customers accounted for all of the Company's accounts receivable, and revenue
from the Company's three largest customers accounted for 86% of the Company's
revenue. Two customers accounted for 80% of the Company's accounts receivable in
1998. No single customer accounted for or exceeded 10% of either revenue or
accounts receivable in 1999.


    (K) STOCK-BASED COMPENSATION


    The Company accounts for stock-based compensation arrangements in accordance
with Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting
for Stock-Based Compensation," which permits entities to recognize as expense
over the vesting period the fair value of all stock-based awards on the date of
grant. Alternatively, SFAS No. 123 allows entities to continue to apply the
provisions of Accounting Principle Board ("APB") Opinion No. 25 and provide pro
forma net earnings (loss) disclosures for employee stock option grants as if the
fair-value-based method defined in SFAS No. 123 had been applied. The Company
has elected to continue to apply the provisions of APB Opinion No. 25 and
provide the pro forma disclosure provisions of SFAS No. 123.


    (L) BASIC AND DILUTED NET LOSS PER SHARE


    The Company calculates earnings per share in accordance with the provisions
of SFAS No. 128, "Earnings Per Share", and the Securities and Exchange
Commission Staff Accounting Bulletin No. 98. Under SFAS No. 128, basic EPS
excludes dilution for common stock equivalents and is computed by dividing
income or loss available to common shareholders by the weighted average number
of common shares outstanding for the period. Diluted EPS reflects the potential
dilution that could occur if securities or other contracts to issue common stock
were exercised or converted into common stock and resulted in the issuance of
common stock. Diluted net loss per

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

(1) SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
share is equal to basic loss per share since all common stock equivalents are
anti-dilutive for each of the periods presented.

    Diluted net loss per common share for the year ended December 31, 1998 and
1999, does not include the effects of options to purchase 197,100 and 3,612,345
shares of common stock, respectively, 0 and 718,749 common stock warrants,
respectively, and 0 and 13,225,431 shares of Series A, Series B and Series C
convertible preferred stock on an "as if" converted basis, respectively, as the
effect of their inclusion is anti-dilutive during each period. There were no
dilutive securities outstanding in 1997.

    The pro forma net loss per share for the year ended December 31, 1999, is
computed by dividing the net loss by the sum of the weighted average number of
shares of common stock outstanding and the shares resulting from the automatic
conversion of all of our outstanding convertible preferred stock, totalling
13,225,431, as if such conversion occurred at the date of original issuance
during 1999. The number of pro forma weighted average shares used in computing
basic and diluted net loss per share is as follows:

</TABLE>


    (M) STOCK SPLIT


    Effective January 20, 1999, the Company authorized and implemented a
10-for-1 stock split in the form of a common stock dividend. Accordingly, all
share and per share information in the accompanying financial statements have
been retroactively restated to reflect the effect of the stock split.

    Effective March 8, 2000, the Company authorized and implemented a 3-for-2
split of shares of the Company's common stock in the form of a common stock
dividend. Accordingly, all common share and per common share information,
warrants and options, in the accompanying financial statements has been
retroactively restated to reflect the effect of the stock split.


    (N) COMPREHENSIVE LOSS


    The Company adopted the provisions of Statement of Financial Accounting
Standards No. 130, "Reporting Comprehensive Income" in 1998. SFAS No. 130
requires the Company to report in its financial statements, in addition to its
net income (loss), comprehensive income (loss), which includes all changes in
equity during a period from non-owner sources including, as

applicable, foreign currency items, minimum pension liability adjustments and
unrealized gains and losses on certain investments in debt and equity
securities. There were no differences between the Company's comprehensive loss
and its net loss for all periods presented.


    (O) SEGMENT REPORTING


    During 1998, the Company adopted the provisions of SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information." SFAS
No. 131 establishes annual and interim reporting standards for operating
segments of a company. SFAS No. 131 requires disclosures of selected
segment-related financial information about products, major customers, and
geographic areas. The Company is organized in a single operating segment for
purposes of making operating decisions and assessing performance. The chief
operating decision maker evaluates performance, makes operating decisions, and
allocates resources based on financial data consistent with the presentation in
the accompanying financial statements.

    The Company's revenues have been earned primarily from customers in the
United States. In addition, all significant operations and assets are based in
the United States. No customer accounted for or exceeded more than 10% of
revenues for the years ended December 31, 1998 and 1999.


    (P) RECENT ACCOUNTING PRONOUNCEMENTS


    In April 1998, the AICPA issued SOP No. 98-5, "Reporting on the Costs of
Start-Up Activities," which provides guidance on the financial reporting of
start-up costs. SOP 98-5 requires costs of start-up activities and organization
costs to be expensed as incurred. SOP 98-5 was adopted by the Company on
January 1, 1999. As the Company had not capitalized such costs, the adoption of
SOP 98-5 did not have an impact on the consolidated financial statements of the
Company.

    In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use." SOP 98-1 provides guidance for
determining whether computer software is internal-use software and on accounting
for the proceeds of computer software originally developed or obtained for
internal use and then subsequently sold to the public. It also provides guidance
on capitalization of the costs incurred for computer software developed or
obtained for internal use. The Company adopted SOP 98-1 in the first quarter of
1999, the effect of which did not have a material effect on the financial
statements.

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including derivative instruments
embedded in other contracts, and for hedging activities. Subsequently, the FASB
issued SFAS No. 137 which deferred the effective date of SFAS No. 133. SFAS
No. 137 is effective for all fiscal quarters of fiscal years beginning after
June 15,

    Prepaid expenses and other current assets at December 31, 1999 principally
included prepayments for various advertising and promotional activities.

(3) NOTE PAYABLE

    On December 17, 1998, the Company received a $100 loan from a venture
capital firm bearing interest at 8% due on February 1, 1999. Interest expense on
the note payable amounted to less than $1 for the year ended December 31, 1998.
The loan was converted into 83,333 shares of Series A convertible preferred
stock as part of the issuance of Series A preferred stock in January 1999 (see
note 4).

(4) CAPITALIZATION

    The Company had 30,000,000 shares of common stock authorized and 9,000,000
shares of preferred stock authorized as of December 31, 1999. On January 27,
2000, the Company increased the number of its authorized shares of common stock
to 35,000,000 and the number of its authorized shares of preferred stock to

(4) CAPITALIZATION (CONTINUED)

    In January 1999, the Company completed a private placement of 2,500,000
shares of Series A Convertible Preferred Stock ("Series A") with 468,749 common
stock warrants at an offering price of $1.20 per Series A share and $0.001 per
warrant. Total proceeds amounted to $2,902. The warrants are exercisable at a
price of $2.40 per common share and have a term of 5 years. None of these
warrants have been exercised. As part of the Series A private placement, a $100
note payable was converted into 83,333 shares of Series A preferred stock.


    In January 1999, the Company issued an additional 41,667 shares of Series A
preferred stock to a financial advisor in exchange for services. The Company
recorded compensation expense of $50 in connection with the issuance of the
shares at $1.20 per share.


    In May 1999, the Company completed a private placement of 1,142,857 shares
of Series B Convertible Preferred Stock ("Series B") with 250,000 common stock
warrants at an offering price of $1.40 per Series B share and $0.001 per
warrant. The warrants are exercisable at a price of $1.60 per common share and
have a term of 5 years. None of these warrants have been exercised. Total
proceeds, net of offering costs of $15, amounted to $1,586.


    The managing underwriter of the Company's IPO can request the Company to
accelerate the expiration of the Series A and Series B warrants to the day
immediately preceding the date on which the Company's registration statement is
declared effective by the SEC. The Company has been informed by the managing
underwriter that it does not intend to do so.


    In July 1999, the Company completed a private placement of 5,132,433 shares
of Series C Redeemable Convertible preferred stock ("Series C") at $3.70 per
share. Total proceeds, net of offering costs of $10, amounted to $18,980. Such
stock is redeemable at $3.70 per share at the option of the holder. 33% of such
shares are subject to mandatory redemption beginning on July 19, 2004, an
additional 17% on July 19, 2005 and the remaining 50% on July 19, 2006.



    In January 2000, LivePerson issued an aggregate of 3,157,895 shares of
Series D Redeemable Convertible preferred stock ("Series D") at $5.70 per share.
Total proceeds, net of offering costs of $100, amounted to $17,900. The
difference between the price of the Series D on an as if conversion basis of
$3.80 and $11.70, or $7.90, multiplied by the number of shares of Series D on an
as if conversion basis is treated as a beneficial conversion feature. The
beneficial conversion feature is treated as a non-cash preferred stock dividend
in the pro forma statement of operations.


    Each share of common stock and Series A, Series B, Series C and Series D
preferred stock has one vote per share. In the event of any liquidation or
winding up of the Company, holders of the Series A, Series B, Series C, and
Series D preferred stock will be entitled, (ranking in preference among
preferred stockholders in the reverse order of issuance), in preference to the
holders of the common stock, to an amount equal to the applicable purchase price
per share plus any accrued but unpaid dividends.


    If the IPO is consummated, upon the closing, 2,541,667, 1,142,857, 5,132,433
and 3,157,895 shares of Series A, Series B, Series C and Series D convertible
preferred stock, respectively,

(5) STOCK OPTIONS (CONTINUED)

    The Company applies APB No. 25 and related interpretations in accounting for
its stock option grants to employees. Accordingly, except as mentioned below, no
compensation expense has been recognized relating to these stock option grants.
Had compensation cost for the Company's stock option grants been determined
based on the fair value at the grant date for awards consistent with the method
of SFAS No. 123, the Company's net loss for each year is presented below. The
Company did not have any employee stock options outstanding prior to January 1,
1998.

</TABLE>


    The resulting effect on the pro forma net loss disclosed for the years ended
December 31, 1998 and 1999 is not likely to be representative of the effects on
the net loss on a pro forma basis in future years, because the pro forma results
include the impact of only one period of grants and related vesting, while
subsequent years will include additional grants and vesting.

    The per share weighted average fair value of stock options granted during
1998 and 1999, was $0.26 and $1.40, respectively. The fair value of each option
grant is estimated on the date of grant using the Black-Scholes option-pricing
model with the following weighted average assumptions used for grants in 1998
and 1999: dividend yield of zero percent for both years, risk-free interest
rates of 5.4 and 6.0%, respectively and expected life of 5 years for both years.
As permitted under the provisions of SFAS No. 123 and based on the historical
lack of a public market for the Company's stock, no factor for volatility has
been reflected in the option pricing calculation. No employee stock options were
granted in 1997.

    During December 1998, the Company granted options to purchase 93,750 shares
of common stock at an exercise price of $0.67 per share, the then fair market
value of the Company's common stock, to a consultant for services performed.
These options are exercisable for a period of 5 years. The Company recorded an
expense of $25 in connection with the issuance of the fully vested options using
a Black-Scholes pricing model using a volatility factor of 40%.


    During April 1999, the Company granted options to purchase an aggregate of
64,260 shares of common stock at an exercise price of $0.67 per share, to four
consultants for services performed. These options are exercisable for a period
of 10 years. The Company recorded an expense of $32 in connection with the
issuance of the fully vested options using a Black-Scholes pricing model using a
volatility factor of 50% and a deemed fair value of $1.08 per share.

(5) STOCK OPTIONS (CONTINUED)

    During May 1999, the Company issued an option to purchase 94,500 shares of
common stock at an exercise price of $1.60 per share to a client in connection
with an agreement by the Company to provide services to the client for a
two-year period. The Company is receiving subscription revenue from the client
over the two-year period based on the number of seats the client is using. There
is no minimum guarantee. This option originally provided that it would vest in
or before May 2001 if the client met certain defined revenue targets and was
exercisable for a period of 3 years from the date of grant. The Company
accounted for this option in accordance with Emerging Issues Task Force Abstract
No. 96-18, "Accounting for Equity Instruments That are Issued to Other Than
Employees for Acquiring, or in Conjunction with Selling, Goods or Services."
Pursuant to EITF 96-18, the Company valued the option at each balance sheet date
using a Black-Scholes pricing model using a volatility factor of 50%, a $1.60
per share exercise price and the then fair value of the Company's common stock
as of each balance sheet date. The $566 value ascribed to the option reflects
the market value at December 31, 1999 and has been recorded as deferred cost.
This cost is being ratably amortized over the two-year contract period, as the
Company believed that the achievement of the revenue targets was probable. The
value ascribed to this option was adjusted at each balance sheet date to bring
the total charge recognized and amortized up to the then current fair value. The
Company has amortized $86 of the deferred costs as of December 31, 1999. In
February 2000, the Company amended the option agreement with the client whereby
the option became fully vested and immediately exercisable. However, the client
is precluded from selling the underlying common stock until the earlier of five
years or, if certain revenue targets are met, by May 19, 2001. The value of the
option at the time the agreement was amended was $1,100, which will be
immediately expensed because the options are fully vested and because the client
has no continuing performance obligations to complete in order to receive the
options.



    During June 1999, the Company granted options to purchase 150,000 shares of
common stock to an advisor at an exercise price of $0.67 per share. These
options are exercisable for a period of 10 years. The Company has recorded
compensation expense of $91 using the Black-Scholes pricing model with a
volatility factor of 50% and a deemed fair value of $0.84 per share.



    In December 1999, the Company recorded compensation expense of approximately
$855 in connection with the options granted to an advisor to purchase 150,000
shares of common stock at an exercise price of $2.00 for services performed.
These options are exercisable for a period of 10 years. The fair value of the
options was determined using a Black-Scholes pricing model with a volatility
factor of 50% and a deemed fair value of $9.94 per share.



    During 1999, the Company granted stock options to purchase 3,496,245 shares
of common stock to employees at a weighted average exercise price of $1.37,
certain of which were granted at less than the deemed fair value of the common
stock at the date of grant. For the year ended December 31, 1999, the Company
recorded deferred compensation of approximately $6,233 in connection with these
options. This amount is presented as deferred compensation within the financial
statements and will be amortized over the vesting period, typically three to
four years, of the applicable options. The Company amortized $1,589 of deferred
compensation for the year ended December 1999. The Company expects to amortize
the following amounts of deferred

    In the first quarter of 2000, the Company entered into two additional leases
for office space. The lease for the Company's San Francisco office space,
entered into in February 2000, provides for annual aggregate payments of $275.
The security deposit for this lease is approximately $300. In February 2000, the
Company entered into a sublease for approximately 8,000 square feet in New York
City expiring in September 2000, providing for annual aggregate payments of
$238. In March 2000, the Company entered into a lease for an aggregate of
approximately 83,500 square feet on two floors at a location in New York City.
The lease with respect to one floor, consisting of approximately 40,500 square
feet, commences in June 2000, at a rent of approximately $1,400 per year in the
first three years, $1,500 per year in years four through seven and $1,600 per
year in years eight through ten. The related security deposit is $2,000 for the
first three years, $1,300 for years four through seven and $670 for years eight
through ten. The other floor consists of approximately 43,000 square feet, and
the lease term relating to that floor commences in August 2001, at a rent of
approximately $1,500 per year in the first three years, $1,600 per year in years
four through seven and $1,700 per year in years eight through ten. The related
security deposit is $2,200 for the first three years, $1,500 for years four
through seven and $747 for years eight through ten. At our option, we may
provide the security deposit by a letter of credit.

    EMPLOYMENT AGREEMENTS

    The Company has employment agreements with 5 senior employees which provide
for severance benefits among other items. In the event these agreements are
terminated, the Company may be liable for severance payments of up to $703 of
salary payable during the year following termination.

(7) INCOME TAXES

    The Company has adopted the cash method of accounting for income tax
purposes. There is no provision for federal, state or local income taxes for any
periods presented, since the Company has incurred losses since inception. At
December 31, 1999, the Company had approximately $5,600 of federal net operating
loss carryforwards available to offset future taxable income. Such carryforwards
expire in various years through 2019. The Company has recorded a full valuation

allowance against its deferred tax assets since management believes that, after
considering all the available objective evidence, it is not more likely than not
that these assets will be realized. The tax effect of temporary differences that
give rise to significant portions of federal deferred tax assets principally
consists of the Company's net operating loss carryforwards.

    Under Section 382 of the Internal Revenue Code of 1986, as amended (the
"Code"), the utilization of net operating loss carryforwards may be limited
under the change in stock ownership rules of the Code. The Company has not yet
determined whether the IPO will result in an ownership change.

    The effects of temporary differences and tax loss carryforwards that give
rise to significant portions of federal deferred tax assets and deferred tax
liabilities at December 31, 1998 and 1999 are presented below.

    In January 2000, the Board of Directors authorized the filing of a
registration statement with the Securities and Exchange Commission ("SEC") that

Company's convertible preferred stock will automatically convert at a ratio of
two shares of preferred stock for three shares of common stock, into an
aggregate of 17,962,273 shares of common stock.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                           DECEMBER 31, 1998 AND 1999

         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1999 IS UNAUDITED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)


(10) SUBSEQUENT EVENTS--UNAUDITED


    Upon the closing of this offering, the Company intends to authorize the
issuance of 5,000,000 shares of preferred stock.

    The Company intends to establish a successor to the 1998 Plan, the 2000
Stock Incentive Plan (the "2000 Plan"). Under the 2000 Plan, the options which
had been outstanding under the 1998 Plan will be incorporated into the 2000 Plan
and the Company will increase the number of options available under the plan by
approximately 4,150,000 options effectively authorizing 10,000,000 options in
the aggregate. These options will have 10 year terms.

    The Company intends to adopt the 2000 Employee Stock Purchase Plan with
450,000 shares of common stock initially reserved for issuance.


    For the period from January 1, 2000 through March 8, 2000, the Company
granted stock options to purchase 2,105,250 shares of common stock,
respectively, to employees at a weighted average exercise price of $3.81. The
deemed fair value of the Company's common stock ranged from $10.30 to $13.00 per
share during such period. For the period from January 1, 2000 through March 8,
2000, the Company recorded deferred compensation of approximately $17,885, in
connection with the grant of certain options to employees, representing the
difference between the deemed fair value of its common stock as of the date of
grant for accounting purposes and the exercise price of the related options.
This amount will be presented as deferred compensation in the financial
statements and will be amortized over the vesting period, typically three to
four years, of the applicable options. The Company expects to amortize the
following amounts of deferred compensation relating to options granted from
January 1, 2000 through March 8, 2000 as follows: 2000-$11,464; 2001-$3,781;
2002-$1,945; and 2003-$695. During the period from January 1, 2000 through
March 8, 2000, 93,750 stock options were exercised at an exercise price of $0.67
per share and 375 options were cancelled at an exercise price of $0.67 per
share.


    During the period from January 1, 2000 through March 8, 2000, 175,781
warrants to purchase common stock at an exercise price of $1.60 per share were
exercised.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The registrant's amended and restated certificate of incorporation in effect
as of the date hereof, and the registrant's amended and restated certificate of
incorporation to be in effect upon the closing of this offering (the
"Certificate") provide that, except to the extent prohibited by the Delaware
General Corporation Law, as amended (the "DGCL"), the registrant's directors
shall not be personally liable to the registrant or its stockholders for
monetary damages for any breach of fiduciary duty as directors of the
registrant. Under the DGCL, the directors have a fiduciary duty to the
registrant which is not eliminated by this provision of the Certificate and, in
appropriate circumstances, equitable remedies such as injunctive or other forms
of non-monetary relief will remain available. In addition, each director will
continue to be subject to liability under the DGCL for any breach of the
director's duty of loyalty to the registrant or its stockholders, for acts or
omissions not in good faith or which involve intentional misconduct, for knowing
violations of law, for actions leading to improper personal benefit to the
director, and for payment of dividends or approval of stock repurchases or
redemptions that are prohibited by the DGCL. This provision also does not affect
the directors' responsibilities under any other laws, such as the Federal
securities laws or state or Federal environmental laws. The registrant has
obtained liability insurance for its officers and directors.

    Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers, provided that this provision
shall not eliminate or limit the liability of a director: (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) arising under Section 174 of the DGCL, or
(iv) for any transaction from which the director derived an improper personal
benefit. The DGCL provides further that the indemnification permitted thereunder
shall not be deemed exclusive of any other rights to which the directors and
officers may be entitled under the corporation's bylaws, any agreement, a vote
of stockholders or otherwise. The Certificate eliminates the personal liability
of directors to the fullest extent permitted by Section 102(b)(7) of the DGCL
and provides that the registrant shall,

                                      II-1
<PAGE>
to the fullest extent permitted by the DGCL, fully indemnify any person who was
or is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding (whether civil, criminal, administrative or
investigative) by reason of the fact that such person is or was, or has agreed
to become, a director or officer of the registrant, or is or was serving at the
request of the registrant as a director, officer or trustee of or, in a similar
capacity with, another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise, or by reason of any action alleged to have
been taken or omitted in such capacity, against all expenses (including
attorney's fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by or on behalf of such person in connection with such
action, suit or proceeding and any appeal therefrom.

    We have also entered into agreements to indemnify our directors and
executive officers, in addition to the indemnification provided for in the
Certificate. We believe that these agreements are necessary to attract and
retain qualified directors and executive officers.

    At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the Certificate or the aforementioned
indemnification agreements. The registrant is not aware of any threatened
litigation or proceeding that may result in a claim for such indemnification.

ITEM 17. UNDERTAKINGS

    The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

    Insofar as indemnification for liabilities arising under the 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 Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in 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 Act and will be governed by the final adjudication of
such issue.

                                      II-4
<PAGE>
    The undersigned registrant hereby undertakes that:

    (1) For purposes of determining any liability under the Act, the information

Prospectus.

     The Company hereby confirms the agreements made with respect to the
purchase of the Stock by the several underwriters, for whom you are acting,
named in Schedule I hereto (herein collectively called the UNDERWRITERS, which
term shall also include any underwriter purchasing Stock pursuant to Section
3(b) hereof). You represent and warrant that you have been authorized by each of
the other Underwriters to enter into this Agreement on its behalf and to act for
it in the manner herein provided.

     1. REGISTRATION STATEMENT. The Company has filed with the Securities and
Exchange Commission (herein called the COMMISSION) a registration statement on
Form S-1 (No. 333-95689), including the related preliminary prospectus, for the
registration under the Securities Act of 1933, as amended (herein called the
SECURITIES ACT) of the Stock. Copies of such registration statement and of each
amendment thereto, if any, including the related preliminary prospectus (meeting
the requirements of Rule 430A of the rules and regulations of the Commission)
heretofore filed by the Company with the Commission have been delivered to you.

     The term REGISTRATION STATEMENT as used in this Agreement shall mean such
registration statement, including all exhibits and financial statements (and the
related notes), all information omitted therefrom in reliance upon Rule 430A and
contained in the Prospectus referred to below, in the form in which it became
effective, and any registration statement filed pursuant to Rule 462(b) of the
rules and regulations of the Commission with respect to the Stock (herein called
a RULE 462(B) REGISTRATION STATEMENT), and, in the event of any amendment
thereto after the effective date of such registration statement (herein called
the EFFECTIVE DATE), shall also mean (from and after the effectiveness of such
amendment) such registration statement as so amended (including any Rule 462(b)
registration statement). The term PROSPECTUS as used in this Agreement shall
mean the prospectus relating to the Stock first filed with the Commission
pursuant to Rule 424(b) and Rule 430A (or if no such filing is required, as
included in the Registration Statement) and, in the event of any supplement or
amendment to such prospectus after the Effective Date, shall also mean (from and
after the date of filing with the Commission of such supplement or the
effectiveness of such amendment) such prospectus as so supplemented or amended.
The term PRELIMINARY PROSPECTUS as used in this Agreement shall mean each
preliminary prospectus included in such registration statement prior to the time
it becomes effective.

     The Registration Statement has been declared effective under the Securities
Act, and no post-effective amendment to the Registration Statement has been
filed as of the date of this Agreement. The Company has caused to be delivered
to you copies of each


                                        2

Preliminary Prospectus and has consented to the use of such copies for the
purposes permitted by the Securities Act.

     2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

     (a) The Company hereby represents and warrants as follows:

          (i) The Company has been duly incorporated and is validly existing as
     a corporation in good standing under the laws of the State of Delaware, has
     full corporate power and authority to own or lease its properties and
     conduct its business as described in the Registration Statement and the
     Prospectus and as being conducted, and is duly qualified as a foreign
     corporation and in good standing in all jurisdictions in which the
     character of the property owned or leased or the nature of the business
     transacted by it makes qualification necessary (except where the failure to
     be so qualified would not result in a Material Adverse Change (as
     hereinafter defined)).

          (ii) The Company has no subsidiaries and does not otherwise own or
     control, directly or indirectly, any corporation, association or other
     entity.

          (iii) Since the respective dates as of which information is given in
     the Registration Statement and the Prospectus, there has not been a
     Material Adverse Change (as hereinafter defined), other than as set forth
     in the Registration Statement and the Prospectus, and since such dates,
     except in the ordinary course of business, the Company has not entered into
     any material transaction not referred to in the Registration Statement and
     the Prospectus. As used herein, MATERIAL ADVERSE CHANGE shall mean a
     materially adverse change in the business, properties, financial condition
     or results of operations of the Company, whether or not arising from
     transactions in the ordinary course of business.

          (iv) The Registration Statement and the Prospectus comply, and on the
     Closing Date (as hereinafter defined) and any later date on which Option
     Stock is to be purchased, the Prospectus will comply, in all material
     respects, with the provisions of the Securities Act and the rules and
     regulations of the Commission thereunder; on the Effective Date, the
     Registration Statement did not contain any untrue statement of a material
     fact and did not omit to state any material fact required to be stated
     therein or necessary in order to make the statements therein not
     misleading; and, on the Effective Date the Prospectus did not and, on the
     Closing Date and any later date on which Option Stock is to be purchased,
     will not contain any untrue statement of a material fact or omit to state
     any material fact necessary in order to make the statements therein, in the
     light of the circumstances


                                        3
<PAGE>

     under which they were made, not misleading; PROVIDED, HOWEVER, that none of
     the representations and warranties in this subparagraph (iv) shall apply to
     statements in, or omissions from, the Registration Statement or the
     Prospectus made in reliance upon and in conformity with information herein
     or otherwise furnished in writing to the Company by or on behalf of the
     Underwriters for use in the Registration Statement or the Prospectus.

          (v) Each of the Registration Statement and any Rule 462(b)
     registration statement has become effective under the Securities Act and no
     stop order suspending the effectiveness of the Registration Statement or
     any Rule 462(b) registration statement has been issued under the Securities
     Act and no proceedings for that purpose have been instituted or are pending
     or, to the knowledge of the Company, are contemplated by the Commission,
     and any request on the part of the Commission for additional information
     has been complied with.

          (vi) The shares of Common Stock outstanding prior to the issuance of
     the Stock have been duly authorized and are validly issued, fully paid and
     non-assessable.

          (vii) The shares of Common Stock to be issued upon the conversion of
     the Series A Convertible Preferred Stock, par value $0.001 per share, the
     Series B Convertible Preferred Stock, par value $0.001 per share, the
     Series C Convertible Preferred Stock, par value $0.001 per share, and the
     Series D Convertible Preferred Stock, par value $0.001 per share
     (collectively, herein called the CONVERTIBLE PREFERRED STOCK), have been
     duly authorized and, when issued and delivered pursuant to the terms of the
     applicable certificates of designation, will be validly issued, fully paid
     and non-assessable. No additional approval or authority of the shareholders
     or the Board of Directors of the Company subsequent to the date hereof will
     be required for such conversion or the issuance of such shares of common
     stock upon such conversion.

          (viii) The Stock, when issued and sold to the Underwriters as provided
     herein, will be duly and validly issued, fully paid and non-assessable and
     conforms to the description thereof in the Prospectus, and the issuance of
     the Stock will not be subject to any preemptive or similar rights which
     have not been waived. No additional approval or authority of the
     shareholders or the Board of Directors of the Company subsequent to the
     date hereof will be required for the issuance and sale of the Stock as
     contemplated herein.

          (ix) Prior to the Closing Date, the Stock to be issued and sold by the
     Company will be approved for quotation on the Nasdaq National Market upon
     official notice of issuance.

          (x) KPMG LLP, the accountants who certified the financial statements
     and supporting schedules included in the Registration Statement, are
     independent public or certified public accountants as required by the
     Securities Act and the rules and regulations promulgated thereunder.

          (xi) The financial statements included in the Registration Statement
     and the Prospectus, together with the related schedules and notes thereto,
     present fairly the financial position of the Company as of and at the dates
     indicated and the statement of operations, stockholders' equity and cash
     flows of the Company for the periods specified. Such financial statements
     have been prepared in conformity with generally accepted accounting
     principles (herein called GAAP) applied on a consistent basis throughout
     the periods involved, except as may be indicated in the notes related
     thereto. The supporting schedules included in the Registration Statement
     present fairly in accordance with GAAP the information required to be
     stated therein. The selected financial data and the summary financial data
     included in the Prospectus present fairly the information shown therein and
     have been compiled on a basis consistent with that of the audited financial
     statements included in the Registration Statement.

          (xii) The information set forth under the caption "Capitalization" in
     the Prospectus is true and correct in all material respects. All of the
     Stock conforms in all material respects to the description thereof
     contained in the Registration Statement. The form of certificates for the
     Stock conforms to the legal requirements of the State of Delaware.

          (xiii) This Agreement has been duly authorized, executed and delivered
     by the Company and is a valid and binding agreement of the Company,
     enforceable in accordance with its terms except insofar as rights to
     indemnification and contribution hereunder may be limited by applicable law
     or equitable principles and except as enforceability may be limited by
     bankruptcy, insolvency, reorganization, moratorium or similar laws relating
     to or affecting creditors' rights generally or by general equitable
     principles.

          (xiv) The Company is not in violation of its Certificate of
     Incorporation or By-laws (each as in effect as of the date hereof) or in
     default in the performance or observance of any obligation, agreement,
     covenant or condition contained in any contract, indenture, mortgage, deed
     of trust, loan or credit

     the issuance and sale of the Stock and the use of the proceeds from the
     sale of the Stock as described in the Prospectus under the caption "Use of
     Proceeds") and compliance by the Company with its obligations under this
     Agreement have been duly authorized by all necessary corporate action and
     do not and will not, whether with or without the giving of notice or
     passage of time or both, 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 pursuant to, any
     agreement or other instrument binding upon the Company that is material to
     the Company, nor will such action result in any violation of the provisions
     of the charter or by-laws of the Company or any applicable law, statute,
     rule, regulation, judgment, order, writ or decree of any government,
     government instrumentality or court, domestic or foreign, having
     jurisdiction over the Company or any of its assets, properties or
     operations.

          (xv) No material labor dispute with the employees of the Company
     exists or, to the knowledge of the Company, is imminent, and the Company is
     not aware of any existing or imminent labor disturbance by the employees of
     any of its principal suppliers, manufacturers, customers or contractors,
     that, in either case, would result in a Material Adverse Change.

          (xvi) There is no action, suit, proceeding, inquiry or investigation
     before or brought by any court or governmental agency or body, domestic or
     foreign, now pending or, to the knowledge of the Company, threatened,
     against or affecting the Company, that is required to be disclosed in the
     Registration Statement (other than as disclosed therein), or that might
     reasonably be expected to result in a Material Adverse Change, or that
     might reasonably be expected to materially and adversely affect the
     consummation of the transactions contemplated in this Agreement or the
     performance by the Company of its obligations hereunder.

          (xvii) There are no contracts or documents which are required to be
     described in the Registration Statement or the Prospectus or to be filed as
     exhibits thereto which have not been so described and filed as required.

          (xviii) Except where the failure to do so would not result in a
     Material Adverse Change, and except as described in the Registration
     Statement or the

     has any knowledge of any infringement or misappropriation of or conflict
     with asserted rights of others with respect to any Patent and Proprietary
     Rights, or of any facts which would render any Patent and Proprietary
     Rights invalid or inadequate to protect the interest of the Company
     therein, and which infringement, misappropriation or conflict or invalidity
     or inadequacy, individually or in the aggregate, would result in a Material
     Adverse Change.

          (xix) No filing with, or authorization, approval, consent, license,
     order, registration, qualification or decree of, any court or governmental
     authority or agency is necessary or required for the performance by the
     Company of its obligations under this Agreement, in connection with the
     offering, issuance or sale of the Stock hereunder or the consummation of

     already obtained or as may be required (A) under the Securities Act or the
     rules and regulations promulgated thereunder, (B) under the Blue Sky
     securities laws of any jurisdiction, (C) by the National Association of

     consents and other authorizations (herein called GOVERNMENTAL LICENSES)
     issued by the appropriate federal, state, local or foreign regulatory
     agencies or bodies necessary to conduct the business now operated by it;
     the Company is in compliance with the terms and conditions of all such
     Governmental Licenses, except where the failure so to comply would not,
     singly or in the aggregate, result in Material Adverse Change; all of the
     Governmental Licenses are valid and in full force and effect, except when
     the invalidity of such Governmental Licenses or the failure of such
     Governmental Licenses to be in full force and effect would not, singly or
     in the aggregate, result in a Material Adverse Change; and the Company has
     not received any notice of proceedings relating to the revocation or
     modification of any such Governmental Licenses which, singly or in the
     aggregate, if the subject of an unfavorable decision, ruling or finding,
     would result in a Material Adverse Change.

          (xxi) The Company does not own any real property. The Company has good
     and marketable title to all other properties and assets owned by it and
     reflected in the financial statements, in each case, free and clear of all
     mortgages, pledges, liens, security interests, claims, restrictions or
     encumbrances of any kind except the irrevocable stand-by letter of credit
     No. T-298456 given by the Company in favor of Vornado 330 West 34th Street
     LLC, entered into in March 2000, and the irrevocable stand-by letter of
     credit No. T-298205, given by the Company in favor of SLK Associates,
     entered into in March 2000, and such as (a) are described in the
     Prospectus, (b) are reflected in the financial statements included in the
     Prospectus or (c) do not, singly or in the aggregate, materially and
     adversely affect the value of such property and do not interfere with the
     use made and proposed to be made of such property by the Company; and all
     of the leases and subleases material to the business of the Company, and
     under which the Company holds properties described in the Prospectus, are
     in full force and effect, and the Company does not have any notice of any
     claim, the adverse determination of which would result in a Material
     Adverse Change, that has been asserted by anyone adverse to the rights of
     the Company under any of the leases or subleases mentioned above, or
     affecting or questioning the rights of the Company to the continued
     possession of the leased or subleased premises under any such lease or
     sublease.

          (xxii) There are no persons with registration rights or other similar

     Securities Act.

          (xxiii) The Company has filed all necessary federal, state, local and
     foreign income, payroll, franchise and other tax returns (after giving

     respect to any of its properties, and there is no tax deficiency that has
     been, or to the knowledge of the Company is likely to be, asserted against
     the Company or any of its properties or assets that would result in a
     Material Adverse Change.

          (xxiv) The Company is insured by insurers of recognized financial
     responsibility against such losses and risks and in such amounts as are
     prudent and customary in the businesses in which they are engaged; the
     Company has not been refused any insurance coverage sought or applied for;
     and the Company has no reason to believe that it will not be able to renew
     its existing insurance coverage as and when such coverage expires or to
     obtain similar coverage from similar insurers as may be necessary to
     continue its business at a cost that would not result in a Material Adverse
     Change, except as described in the Prospectus.

     sufficient to provide reasonable assurances that (A) transactions are

          (xxvi) To the best of the Company's knowledge, neither the Company nor
     any employee or agent of the Company has made any payment of funds of the

     Act.

          (xxvii) The Company and each member of its Control Group (as defined
     below) is in compliance in all material respects with all presently

     of 1974, as amended (herein called ERISA), and the regulations and
     published interpretations thereunder; no "reportable event" (as defined in
     ERISA and the regulations and published interpretations thereunder) has
     occurred with respect to any material "pension plan" (as defined in ERISA
     and the regulations and published interpretations thereunder) established
     or maintained by the Company or any member of its Control Group; neither
     the Company nor any member of its Control Group has incurred nor expects to

     called the CODE); and each material "pension plan" established or
     maintained by the Company that is intended to be qualified under Section
     401(a) of the Code is so qualified in all material respects and has
     received a favorable determination letter as to its qualification and

     "Control Group" is defined to include any entity which is part of a group
     which includes the Company and is treated as a single employer under
     Section 414 of the Code.

          (xxxi) The Company has not offered, or caused Chase to offer, Stock to

     3. PURCHASE OF THE STOCK BY THE UNDERWRITERS.

     (a) On the basis of the representations and warranties and subject to the
terms and conditions herein set forth, the Company agrees to issue and sell
4,000,000 shares


                                       10
<PAGE>

of the Underwritten Stock to the several Underwriters and each of the
Underwriters agrees to purchase from the Company the respective number of shares
of Underwritten Stock set forth opposite its name in Schedule I. The price at
which such shares of Underwritten Stock shall be sold by the Company and
purchased by the several Underwriters shall be $___ per share. In making this
Agreement, each Underwriter is contracting severally and not jointly; except as
provided in paragraphs (b) and (c) of this Section 3, the agreement of each
Underwriter is to purchase only the respective number of shares of the
Underwritten Stock specified in Schedule I.

     (b) If for any reason one or more of the Underwriters shall fail or refuse
(otherwise than for a reason sufficient to justify the termination of this
Agreement under the provisions of Section 8 or 9 hereof) to purchase and pay for
the number of shares of the Stock agreed to be purchased by such Underwriter or
Underwriters, the Company shall immediately give notice thereof to you, and the
non-defaulting Underwriters shall have the right within 24 hours after the
receipt by you of such notice to purchase, or procure one or more other
Underwriters to purchase, in such proportions as may be agreed upon between you
and such purchasing Underwriter or Underwriters and upon the terms herein set
forth, all or any part of the shares of the Stock which such defaulting
Underwriter or Underwriters agreed to purchase. If the non-defaulting
Underwriters fail so to make such arrangements with respect to all such shares
and portion, the number of shares of the Stock which each non-defaulting
Underwriter is otherwise obligated to purchase under this Agreement shall be
automatically increased on a pro rata basis to absorb the remaining shares and
portion which the defaulting Underwriter or Underwriters agreed to purchase;
PROVIDED, HOWEVER, that the non-defaulting Underwriters shall not be obligated
to purchase the shares and portion which the defaulting Underwriter or
Underwriters agreed to purchase if the aggregate number of such shares of the
Stock exceeds 10% of the total number of shares of the Stock which all
Underwriters agreed to purchase hereunder. If the total number of shares of the
Stock which the defaulting Underwriter or Underwriters agreed to purchase shall
not be purchased or absorbed in accordance with the two preceding sentences, the
Company shall have the right, within 24 hours next succeeding the 24-hour period
above referred to, to make arrangements with other underwriters or purchasers
satisfactory to you for purchase of such shares and portion on the terms herein
set forth. In any such case, either you or the Company shall have the right to
postpone the Closing Date determined as provided in Section 5 hereof for not
more than seven business days after the date originally fixed as the Closing
Date pursuant to said Section 5 in order that any necessary changes in the
Registration Statement, the Prospectus or any other documents or arrangements
may be made. If neither the non-defaulting Underwriters nor the Company shall
make arrangements within the 24-hour periods stated above for the purchase of
all the shares of the Stock which the defaulting Underwriter or Underwriters
agreed to purchase hereunder, this Agreement shall be terminated without further
act or deed and without any liability on the part of the Company to any
non-defaulting


                                       11
<PAGE>

Underwriter and without any liability on the part of any non-defaulting
Underwriter to the Company. Nothing in this paragraph (b), and no action taken
hereunder, shall relieve any defaulting Underwriter from liability in respect of
any default of such Underwriter under this Agreement.

     (c) On the basis of the representations, warranties and covenants herein
contained, and subject to the terms and conditions herein set forth, the Company
hereby grants an option to the several Underwriters to purchase, severally and
not jointly, up to 600,000 shares in the aggregate of the Option Stock from the
Company at the same price per share as the Underwriters shall pay for the
Underwritten Stock. Said option may be exercised only to cover over-allotments
in the sale of the Underwritten Stock by the Underwriters and may be exercised
in whole or in part at any time (but not more than once) on or before the
thirtieth day after the date of this Agreement, upon written or facsimile notice
by you to the Company setting forth the aggregate number of shares of the Option
Stock as to which the several Underwriters are exercising the option. Delivery
of certificates for the shares of Option Stock, and payment therefor, shall be
made as provided in Section 5 hereof. The number of shares of the Option Stock
to be purchased by each Underwriter shall be the same percentage of the total
number of shares of the Option Stock to be purchased by the several Underwriters
as such Underwriter is purchasing of the Underwritten Stock, as adjusted by you
in such manner as you deem advisable to avoid fractional shares.

     4. OFFERING BY UNDERWRITERS.

     (a) The terms of the initial public offering by the Underwriters of the
Stock to be purchased by them shall be as set forth in the Prospectus. The
Underwriters may from time to time change the public offering price after the
closing of the initial public offering and increase or decrease the concessions
and discounts to dealers as they may determine.

     (b) The information set forth in the last paragraph on the front cover page
and under "Underwriting" in the Registration Statement, any Preliminary
Prospectus and the Prospectus relating to the Stock filed by the Company
(insofar as such information relates to the Underwriters) constitutes the only
information furnished by the Underwriters to the Company for inclusion in the
Registration Statement, any Preliminary Prospectus, and the Prospectus, and you
on behalf of the respective Underwriters represent and warrant to the Company
that the statements made therein are correct.

     5. DELIVERY OF AND PAYMENT FOR THE STOCK.

     (a) Delivery of certificates for the shares of the Underwritten Stock and
the Option Stock (if the option granted by Section 3(c) hereof shall have been
exercised not


                                       12
<PAGE>

later than 7:00 a.m., San Francisco time, on the date two business days
preceding the Closing Date), and payment therefor, shall be made at the office
of Brobeck, Phleger & Harrison LLP, 1633 Broadway, 47th Floor, New York, New
York 10019, at 7:00 a.m., San Francisco time, on the third business day after
the date of this Agreement (the fourth business day after the day of this
Agreement if this Agreement is executed and delivered after 1.30 p.m., San
Francisco time), or at such time on such other day, not later than seven full
business days after such third (or fourth, as the case may be) business day, as
shall be agreed upon in writing by the Company and you. The date and hour of
such delivery and payment (which may be postponed as provided in Section 3(b)
hereof) are herein called the CLOSING DATE.

     (b) If the option granted by Section 3(c) hereof shall be exercised after
7:00 a.m., San Francisco time, on the date two business days preceding the
Closing Date, delivery of certificates for the shares of Option Stock, and
payment therefor, shall be made at the office of Brobeck, Phleger & Harrison
LLP, 1633 Broadway, 47th Floor, New York, New York 10019, at 7:00 a.m., San
Francisco time, on the third business day after the exercise of such option.

     (c) Payment for the Stock purchased from the Company shall be made to the
Company or its order, at the Company's option, by wire transfer of immediately
available funds to an account or accounts designated by the Company or by one or
more certified or official bank check or checks in same day funds. Such payment
shall be made upon delivery of certificates for the Stock to you for the
respective accounts of the several Underwriters against receipt therefor signed
by you. Certificates for the Stock to be delivered to you shall be registered in
such name or names and shall be in such denominations as you may request at
least one business day before the Closing Date, in the case of Underwritten
Stock, and at least one business day prior to the purchase thereof, in the case
of the Option Stock. Such certificates will be made available to the
Underwriters for inspection, checking and packaging at the offices of Lewco
Securities Corporation, 2 Broadway, New York, New York 10004 on the business day
prior to the Closing Date or, in the case of the Option Stock, by 3:00 p.m., New
York time, on the business day preceding the date of purchase.

     It is understood that you, individually and not on behalf of the
Underwriters, may (but shall not be obligated to) make payment to the Company
for shares to be purchased by any Underwriter whose wire transfer or check shall
not have been received by you on the Closing Date or any later date on which
Option Stock is purchased for the account of such Underwriter. Any such payment
by you shall not relieve such Underwriter from any of its obligations hereunder.

     6. FURTHER AGREEMENTS OF THE COMPANY. The Company covenants and agrees as
follows:

     (a) The Company will (i) prepare and timely file with the Commission under
Rule 424(b) a Prospectus containing information previously omitted at the time
of effectiveness of the Registration Statement in reliance on Rule 430A and (ii)
not file any amendment to the Registration Statement or supplement to the
Prospectus of which you shall not previously have been advised and furnished
with a copy or to which you shall have reasonably objected in writing or which
is not in compliance with the Securities Act or the rules and regulations of the
Commission thereunder.

     (b) The Company will promptly notify each Underwriter in the event of (i)
the request by the Commission for amendment of the Registration Statement or for
supplement to the Prospectus or for any additional information, (ii) the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement, (iii) the institution or notice of intended institution
of any action or proceeding for that purpose, (iv) the receipt by the Company of
any notification with respect to the suspension of the qualification of the
Stock for sale in any jurisdiction, or (v) the receipt by it of notice of the
initiation or threatening of any proceeding for such purpose. The Company will
make every reasonable effort to prevent the issuance of such a stop order and,
if such an order shall at any time be issued, to obtain the withdrawal thereof
at the earliest possible moment.

     (c) The Company will (i) on or before the Closing Date, deliver to you a
signed copy of the Registration Statement as originally filed and of each
amendment thereto filed prior to the time the Registration Statement becomes
effective and, promptly upon the filing thereof, a signed copy of each
post-effective amendment, if any, to the Registration Statement (together with,
in each case, all exhibits thereto unless previously furnished to you) and will
also deliver to you, for distribution to the Underwriters, a sufficient number
of additional conformed copies of each of the foregoing (but without exhibits)
so that one copy of each may be distributed to each Underwriter, (ii) as
promptly as possible deliver to you and send to the several Underwriters, at
such office or offices as you may designate, as many copies of the Prospectus as
you may reasonably request and (iii) thereafter from time to time during the
period in which a prospectus is required by law to be delivered by an
Underwriter or dealer, likewise send to the Underwriters as many additional
copies of the Prospectus and as many copies of any supplement to the Prospectus
and of any amended prospectus, filed by the Company with the Commission, as you
may reasonably request for the purposes contemplated by the Securities Act.

     (d) If at any time during the period in which a prospectus is required by
law to be delivered by an Underwriter or dealer any event relating to or
affecting the Company, or of which the Company shall be advised in writing by
you, shall occur as a result of which


                                       14
<PAGE>

it is necessary, in the opinion of counsel for the Company or of counsel for the
Underwriters, to supplement or amend the Prospectus in order to make the
Prospectus not misleading in the light of the circumstances existing at the time
it is delivered to a purchaser of the Stock, the Company will forthwith prepare
and file with the Commission a supplement to the Prospectus or an amended
prospectus so that the Prospectus as so supplemented or amended will not contain
any untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements therein, in the light of the
circumstances existing at the time such Prospectus is delivered to such
purchaser, not misleading. If, after the initial public offering of the Stock by
the Underwriters and during such period, the Underwriters shall propose to vary
the terms of offering thereof by reason of changes in general market conditions
or otherwise, you will advise the Company in writing of the proposed variation,
and, if in the opinion either of counsel for the Company or of counsel for the
Underwriters such proposed variation requires that the Prospectus be
supplemented or amended, the Company will forthwith prepare and file with the
Commission a supplement to the Prospectus or an amended prospectus setting forth
such variation. The Company authorizes the Underwriters and all dealers to whom
any of the Stock may be sold by the several Underwriters to use the Prospectus,
as from time to time amended or supplemented, in connection with the sale of the
Stock in accordance with the applicable provisions of the Securities Act and the
applicable rules and regulations thereunder for such period.

     (e) Prior to the filing thereof with the Commission, the Company will
submit to you, for your information, a copy of any post-effective amendment to
the Registration Statement and any supplement to the Prospectus or any amended
prospectus proposed to be filed.

     (f) The Company will cooperate, when and as requested by you, in the
qualification of the Stock for offer and sale under the securities or Blue Sky
laws of such jurisdictions as you may designate and, during the period in which
a prospectus is required by law to be delivered by an Underwriter or dealer, in
keeping such qualifications in good standing under said securities or Blue Sky
laws; PROVIDED, HOWEVER, that the Company shall not be obligated to file any
general consent to service of process or to qualify as a foreign corporation in
any jurisdiction in which it is not so qualified. The Company will, from time to
time, prepare and file such statements, reports, and other documents as are or
may be required to continue such qualifications in effect for so long a period
as you may reasonably request for distribution of the Stock.

     (g) During a period of five years commencing with the date hereof, the
Company will furnish or make available to you, and to each Underwriter who may
so request in writing, copies of all reports furnished to shareholders of the
Company and of all information, documents and reports filed with the Commission.

expenses incident to (i) the preparation, printing and filing with the
Commission and the National Association of Securities Dealers, Inc. of the
Registration Statement, any Preliminary Prospectus and the Prospectus, (ii) the
furnishing to the Underwriters of copies of any Preliminary Prospectus and of
the several documents required by paragraph (c) of this Section 6 to be so
furnished, (iii) the printing of this Agreement and related documents delivered
to the Underwriters, (iv) the preparation, printing and filing of all
supplements and amendments to the Prospectus referred to in paragraph (d) of
this Section 6, (v) the furnishing to you and the Underwriters of the reports
and information referred to in paragraph (g) of this Section 6 and (vi) the
printing and issuance of stock certificates, including the transfer agent's
fees.

     (j) The Company agrees to reimburse you, for the account of the several
Underwriters, for Blue Sky fees and related disbursements (including counsel
fees and disbursements and cost of printing memoranda for the Underwriters) paid
by or for the account of the Underwriters or their counsel in qualifying the
Stock under state securities or blue sky laws and in the review of the offering
by the NASD.

     (k) The Company agrees to pay all fees and disbursements of counsel
incurred by the Underwriters in connection with the Directed Share Program and
stamp duties, similar taxes or duties and other taxes, if any, incurred by the
Underwriters in connection with the Directed Share Program.

     (l) The Company hereby agrees that, without the prior written consent of
Chase on behalf of the Underwriters, the Company will not, for a period of 180
days following the commencement of the public offering of the Stock by the
Underwriters, directly or indirectly, (i) sell, offer, contract to sell, make
any short sale, pledge, sell any option or contract to purchase, purchase any
option or contract to sell, grant any option, right or warrant to purchase or
otherwise transfer or dispose of any shares of Common Stock or any securities
convertible into or exchangeable or exercisable for or any rights to purchase or
acquire Common Stock or (ii) enter into any swap or other agreement that
transfers, in whole or in part, any of the economic consequences or ownership of
Common Stock, whether any such transaction described in clause (i) or (ii) above
is to be settled by delivery of Common Stock or such other securities, in cash
or otherwise. The foregoing


                                       16
<PAGE>


sentence shall not apply to (A) the sale of the Stock to the Underwriters
pursuant to this Agreement, (B) the issuance of shares of Common Stock by the
Company upon the exercise of options granted under the 2000 Stock Incentive Plan
or under the Employee Stock Purchase Plan of the Company or upon the exercise of
warrants outstanding as of the date hereof, all as described under the caption
"Capitalization" in the Preliminary Prospectus, and (C) the grant of options to
purchase Common Stock under the 2000 Stock Incentive Plan.

     (m) If at any time during the 25-day period after the Registration
Statement becomes effective any rumor, publication or event relating to or
affecting the Company shall occur as a result of which in your opinion the
market price for the Stock has been or is likely to be materially affected
(regardless of whether such rumor, publication or event necessitates a
supplement to or amendment of the Prospectus), the Company will, after written
notice from you advising the Company to the effect set forth above, forthwith
consult with its legal counsel and should the Company, in its reasonable
discretion, determine that a response to such rumor, publication or event is
appropriate, the Company will prepare, consult with you concerning the substance
of, and disseminate a press release or other public statement, reasonably
satisfactory to you, responding to or commenting on such rumor, publication or
event.

     (n) The Company is familiar with the Investment Company Act of 1940, as
amended, and has in the past conducted its affairs, and will in the future
conduct its affairs, in such a manner to ensure that the Company was not and
will not be an "investment company" or a company "controlled" by an "investment
company" within the meaning of the Investment Company Act of 1940, as amended,
and the rules and regulations thereunder.

     (o) The Company will place stop transfer orders on any Directed Shares that
have been sold to Participants that are subject to the three-month restriction
on sale, transfer, assignment, pledge or hypothecation imposed by the NASD under
its Interpretative Material 2110-1 on free-riding and withholding to the extent
necessary to ensure compliance with the three-month restrictions.

     (p) The Company will comply with all applicable securities and other
applicable laws, rules and regulations in each jurisdiction in which the
Directed Shares are offered in connection with the Directed Share Program.

     7. INDEMNIFICATION AND CONTRIBUTION.

     (a) The Company agrees to indemnify and hold harmless each Underwriter and
each person (including each partner or officer thereof) who controls any
Underwriter within the meaning of Section 15 of the Securities Act or Section 20
of the Securities Exchange Act of 1934 (herein called the EXCHANGE ACT) from and
against any and all losses, claims, damages or liabilities, joint or several, to
which such indemnified parties or any of them may become subject under the
Securities Act, the Exchange Act, or the common law or otherwise, and the
Company agrees to reimburse each such Underwriter and controlling person for any
legal or other expenses (including, except as otherwise hereinafter provided,
reasonable fees and disbursements of counsel) incurred by the respective
indemnified parties in connection with defending against any such losses,
claims, damages or liabilities or in connection with any investigation or
inquiry of, or other proceeding which may be brought against, the respective
indemnified parties, in each case arising out of or based upon (i) any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement (including the Prospectus as part thereof and any Rule
462(b) registration statement) or any post-effective amendment thereto
(including any Rule 462(b) registration statement), or the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or (ii) any untrue
statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus or the Prospectus (as amended or as supplemented if the
Company shall have filed with the Commission any amendment thereof or supplement
thereto) or the omission or alleged omission to state therein a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; PROVIDED, HOWEVER,
that (i) the indemnity agreements of the Company contained in this paragraph (a)
shall not apply to any such losses, claims, damages, liabilities or expenses if
such statement or omission was made in reliance upon and in conformity with
information furnished as herein stated or otherwise furnished in writing to the
Company by such Underwriter through you expressly for use in any Preliminary
Prospectus or the Registration Statement or the Prospectus or any such amendment
thereof or supplement thereto and (2) the indemnity agreement contained in this
paragraph (a) with respect to any Preliminary Prospectus shall not inure to the
benefit of any Underwriter from whom the person asserting any such losses,
claims, damages, liabilities or expenses purchased the Stock which is the
subject thereof (or to the benefit of any person controlling such Underwriter)
if at or prior to the written confirmation of the sale of such Stock a copy of
the Prospectus (or the Prospectus as amended or supplemented) was not sent or
delivered to such person and the untrue statement or omission of a material fact
contained in such Preliminary Prospectus was corrected in the Prospectus (or as
the Prospectus as amended or supplemented) unless the failure is the result of
noncompliance by the Company with paragraph (c) of Section 6 hereof. The
indemnity agreements of the Company contained in this paragraph (a) and the
representations and warranties of the


                                       18
<PAGE>

Company contained in Section 2 hereof shall remain operative and in full force
and effect regardless of any investigation made by or on behalf of any
indemnified party and shall survive the delivery of and payment for the Stock.

     (b) Each Underwriter severally agrees to indemnify and hold harmless the
Company, each of its officers who signs the Registration Statement on his own
behalf or pursuant to a power of attorney, each of its directors, each other
Underwriter and each person (including each partner or officer thereof) who
controls the Company or any such other Underwriter within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act, from and against any
and all losses, claims, damages or liabilities, joint or several, to which such
indemnified parties or any of them may become subject under the Securities Act,
the Exchange Act, or the common law or otherwise and to reimburse each of them
for any legal or other expenses (including, except as otherwise hereinafter
provided, reasonable fees and disbursements of counsel) incurred by the
respective indemnified parties in connection with defending against any such
losses, claims, damages or liabilities or in connection with any investigation
or inquiry of, or other proceeding which may be brought against, the respective
indemnified parties, in each case arising out of or based upon (i) any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement (including the Prospectus as part thereof and any Rule
462(b) registration statement) or any post-effective amendment thereto
(including any Rule 462(b) registration statement), or the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading or (ii) any untrue
statement or alleged untrue statement of a material fact contained in the
Prospectus (as amended or as supplemented if the Company shall have filed with
the Commission any amendment thereof or supplement thereto) or the omission or
alleged omission to state therein a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, if such statement or omission was made in reliance upon
and in conformity with information furnished as herein stated or otherwise
furnished in writing to the Company by such indemnifying Underwriter through you
expressly for use in the Registration Statement or the Prospectus or any such
amendment thereof or supplement thereto. The indemnity agreement of each
Underwriter contained in this paragraph (b) shall remain operative and in full
force and effect regardless of any investigation made by or on behalf of any
indemnified party and shall survive the delivery of and payment for the Stock.

     (c) Each party indemnified under the provision of paragraphs (a) and (b) of
this Section 7 agrees that, upon the service of a summons or other initial legal
process upon it in any action or suit instituted against it or upon its receipt
of written notification of the commencement of any investigation or inquiry of,
or proceeding against, it in respect of which indemnity may be sought on account
of any indemnity agreement contained in such paragraphs, it will promptly give
written notice (herein called the NOTICE) of such service


                                       19
<PAGE>

or notification to the party or parties from whom indemnification may be sought
hereunder. No indemnification provided for in such paragraphs shall be available
to any party who shall fail so to give the Notice if the party to whom such
Notice was not given was unaware of the action, suit, investigation, inquiry or
proceeding to which the Notice would have related and was prejudiced by the
failure to give the Notice, but the omission so to notify such indemnifying
party or parties of any such service or notification shall not relieve such
indemnifying party or parties from any liability which it or they may have to
the indemnified party for contribution or otherwise than on account of such
indemnity agreement. Any indemnifying party shall be entitled at its own expense
to participate in the defense of any action, suit or proceeding against, or
investigation or inquiry of, an indemnified party. Any indemnifying party shall
be entitled, if it so elects within a reasonable time after receipt of the
Notice by giving written notice (herein called the NOTICE OF DEFENSE) to the
indemnified party, to assume (alone or in conjunction with any other
indemnifying party or parties) the entire defense of such action, suit,
investigation, inquiry or proceeding, in which event such defense shall be
conducted, at the expense of the indemnifying party or parties, by counsel
chosen by such indemnifying party or parties and reasonably satisfactory to the
indemnified party or parties; PROVIDED, HOWEVER, that (i) if the indemnified
party or parties reasonably determine that there may be a conflict between the
positions of the indemnifying party or parties and of the indemnified party or
parties in conducting the defense of such action, suit, investigation, inquiry
or proceeding or that there may be legal defenses available to such indemnified
party or parties different from or in addition to those available to the
indemnifying party or parties, then counsel for the indemnified party or parties
shall be entitled to conduct the defense to the extent reasonably determined by
such counsel to be necessary to protect the interests of the indemnified party
or parties and (ii) in any event, the indemnified party or parties shall be
entitled to have counsel chosen by such indemnified party or parties participate
in, but not conduct, the defense. It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such indemnified parties and that all such fees
and expenses shall be reimbursed as they are incurred. Such firm shall be
designated in writing by Chase, in the case of parties indemnified pursuant to
paragraph (a) of this Section 7, and by the Company, in the case of parties
indemnified pursuant to paragraph (b) of this Section 7. If, within a reasonable
time after receipt of the Notice, an indemnifying party gives a Notice of
Defense and the counsel chosen by the indemnifying party or parties is
reasonably satisfactory to the indemnified party or parties, the indemnifying
party or parties will not be liable under paragraphs (a) through (c) of this
Section 7 for any legal or other expenses subsequently incurred by the
indemnified party or parties in connection with the defense of the action, suit,
investigation, inquiry or proceeding, except that (A) the indemnifying party or
parties shall bear the legal and other expenses incurred in connection with the
conduct of the defense as referred to in clause (i) of the proviso to the
preceding sentence


                                       20
<PAGE>

and (B) the indemnifying party or parties shall bear such other expenses as it
or they have authorized to be incurred by the indemnified party or parties. If,
within a reasonable time after receipt of the Notice, no Notice of Defense has
been given, the indemnifying party or parties shall be responsible for any legal
or other expenses incurred by the indemnified party or parties in connection
with the defense of the action, suit, investigation, inquiry or proceeding.

     (d) If the indemnification provided for in this Section 7 is unavailable or
insufficient to hold harmless an indemnified party under paragraph (a) or (b) of
this Section 7, then each indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of the losses, claims, damages or liabilities
referred to in paragraph (a) or (b) of this Section 7, (i) in such proportion as
is appropriate to reflect the relative benefits received by each indemnifying
party from the offering of the Stock 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 each indemnifying party in connection with
the statements or omissions that resulted in such losses, claims, damages or
liabilities, or actions in respect thereof, as well as any other relevant
equitable considerations. The relative benefits received by the Company and the
Underwriters shall be deemed to be in the same respective proportions as the
total net proceeds from the offering of the Stock received by the Company and
the total underwriting discount received by the Underwriters, as set forth in
the table on the cover page of the Prospectus, bear to the aggregate public
offering price of the Stock. Relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by each indemnifying party and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such untrue statement or omission.

     The parties agree that it would not be just and equitable if contributions
pursuant to this paragraph (d) were to be 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 into account the equitable
considerations referred to in the first sentence of this paragraph (d). The
amount paid by an indemnified party as a result of the losses, claims, damages
or liabilities, or actions in respect thereof, referred to in the first sentence
of this paragraph (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigation,
preparing to defend or defending against any action or claim which is the
subject of this paragraph (d). Notwithstanding the provisions of this paragraph
(d), no Underwriter shall be required to contribute any amount in excess of the
underwriting discount applicable to the Stock purchased by such Underwriter. No
person guilty of fraudulent misrepresentation (within


                                       21
<PAGE>

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 in this paragraph (d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

     Each party entitled to contribution agrees that upon the service of a
summons or other initial legal process upon it in any action instituted against
it in respect of which contribution may be sought, it will promptly give written
notice of such service to the party or parties from whom contribution may be
sought, but the omission so to notify such party or parties of any such service
shall not relieve the party from whom contribution may be sought from any
obligation it may have hereunder or otherwise (except as specifically provided
in paragraph (c) of this Section 7).

     (e) The Company will not, without the prior written consent of each
Underwriter, settle or compromise or consent to the entry of any judgment in any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification may be sought hereunder (whether or not such Underwriter or any
person who controls such Underwriter within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act is a party to such claim,
action, suit or proceeding) unless such settlement, compromise or consent
includes an unconditional release of such Underwriter and each such controlling
person from all liability arising out of such claim, action, suit or proceeding.

     8. DIRECTED SHARE PROGRAM INDEMNIFICATION AND CONTRIBUTION.

     (a) The Company agrees to indemnify and hold harmless Chase and each
person, if any, who controls Chase within the meaning of either Section 15 of
the Securities Act or Section 20 of the Exchange Act (herein called the CHASE
ENTITIES), from and against any and all losses, claims, damages and liabilities
(including, without limitation, any legal or other expenses reasonably incurred
in connection with defending or investigating any such action or claim) (i)
caused by any untrue statement or alleged untrue statement of a material fact
contained in any material prepared by or with the consent of the Company for
distribution to Participants in connection with the Directed Share Program, or
caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading; (ii) caused by the failure of any Participant to pay for and accept
delivery of Directed Shares that the Participant has agreed to purchase; or
(iii) related to, arising out of, or in connection with the Directed Share
Program, including those arising out of any violation or alleged violation of
the Act or out of any rescission right of any person in respect thereof, other
than losses, claims, damages or liabilities (or expenses relating thereto) that
are finally judicially determined to have resulted from the bad faith or gross
negligence of Chase Entities.


                                       22
<PAGE>

     (b) Upon the service of a summons or other initial legal process upon any
Chase Entity in any action or suit instituted against it or upon its receipt of
written notification of the commencement of any investigation or inquiry of, or
proceeding against, it in respect of which indemnity may be sought pursuant to
Section 8(a), the Chase Entity seeking indemnity will promptly give Notice of
such service or notification to the Company. No indemnification provided for in
Section 8(a) shall be available to any Chase Entity who shall fail so to give
the Notice to the Company if the Company was unaware of the action, suit,
investigation, inquiry or proceeding to which the Notice would have related and
was prejudiced by the failure to give the Notice, but the omission so to notify
the Company of any such service or notification shall not relieve the Company
from any liability which it may have to any such Chase Entity for contribution
or otherwise than on account of such indemnity agreement in Section 8(a). Any
Chase Entity shall be entitled at its own expense to participate in the defense
of any action, suit or proceeding against, or investigation or inquiry of, such
Chase Entity. The Company shall be entitled, if it so elects within a reasonable
time after receipt of the Notice by giving a Notice of Defense to any such Chase
Entity, to assume the entire defense of such action, suit, investigation,
inquiry or proceeding, in which event such defense shall be conducted, at the
expense of the Company, by counsel chosen by the Company and reasonably
satisfactory to such Chase Entity; PROVIDED, HOWEVER, that (i) if any such Chase
Entity reasonably determines that there may be a conflict between the positions
of the Company and of any such Chase Entity in conducting the defense of such
action, suit, investigation, inquiry or proceeding or that there may be legal
defenses available to such Chase Entity different from or in addition to those
available to the Company, then counsel for such Chase Entity shall be entitled
to conduct the defense to the extent reasonably determined by such counsel to be
necessary to protect the interests of such Chase Entity and (ii) in any event,
the Chase Entity shall be entitled to have counsel chosen by such Chase Entity
participate in, but not conduct, the defense. It is understood that the Company
shall not, in respect of the legal expenses of any such Chase Entity in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such Chase Entities and that all such fees and
expenses shall be reimbursed as they are incurred. Such firm shall be designated
in writing by Chase. If, within a reasonable time after receipt of the Notice,
the Company gives a Notice of Defense in connection with this Section 8 and the
counsel chosen by the Company is reasonably satisfactory to the Chase Entity,
the Company will not be liable under Section 8(a) for any legal or other
expenses subsequently incurred by any such Chase Entity in connection with the
defense of the action, suit, investigation, inquiry or proceeding, except that
(A) the Company shall bear the legal and other expenses incurred in connection
with the conduct of the defense as referred to in clause (i) of the proviso to
the preceding sentence and (B) the Company shall bear such other expenses as it
or they have authorized to be incurred by any such Chase Entity. If, within a
reasonable time after


                                       23
<PAGE>

receipt of the Notice, no Notice of Defense has been given, the Company shall be
responsible for any legal or other expenses incurred by any such Chase Entity in
connection with the defense of the action, suit, investigation, inquiry or
proceeding.

     (c) If the indemnification provided for in Section 8(a) is unavailable or
insufficient to hold harmless a Chase Entity under Section 8(a), then the
Company, in lieu of indemnifying the Chase Entity, shall contribute to the
amount paid or payable by the Chase Entity as a result of the losses, claims,
damages or liabilities referred to in Section 8(a), (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the Chase Entities on the other hand from the offering of the Directed
Shares or (ii) if the allocation provided by clause 8(c)(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 8(c)(i) above but also the
relative fault of the Company on the one hand and of the Chase Entities on the
other hand in connection with the statements, acts or omissions that resulted in
such losses, claims, damages or liabilities, or actions in respect thereof, as
well as any other relevant equitable considerations. The relative benefits
received by the Company on the one hand and the Chase Entities on the other hand
in connection with the offering of the Directed Shares shall be deemed to be in
the same respective proportions as the total net proceeds from the offering of
the Directed Shares (before deducting expenses) and the total underwriting
discounts and commissions received by the Chase Entities for the Directed
Shares, bear to the aggregate public offering price of the Stock. Relative fault
of the Company on the one hand and the Chase Entities on the other hand shall be
determined by reference to, among other things, whether the statement, act or
omission that resulted in losses, claims, damages or liabilities relates to
statements, acts or omissions by the Company or by the Chase Entities and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statements, acts or omissions.

     (d) The Company and the Chase Entities agree that it would not be just and
equitable if contributions pursuant to this Section 8 were to be determined by
PRO RATA allocation (even if the Chase Entities were treated as one entity for
such purpose) or by any other method of allocation which does not take into
account the equitable considerations referred to in Section 8(c). The amount
paid by the Chase Entities as a result of the losses, claims, damages or
liabilities, or actions in respect thereof, referred to in the immediately
preceding paragraph shall be deemed to include any legal or other expenses
reasonably incurred by the Chase Entities in connection with investigation,
preparing to defend or defending against any action or claim which is the
subject of Section 8(c). Notwithstanding the provisions of this Section 8, no
Chase Entity shall be required to contribute any amount in excess of the
underwriting discount applicable to the Directed Shares distributed to the
public by such Chase Entity. No person guilty of fraudulent misrepresentation
(within the


                                       24
<PAGE>

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.

     Each party entitled to contribution agrees that upon the service of a
summons or other initial legal process upon it in any action instituted against
it in respect of which contribution may be sought, it will promptly give written
notice of such service to the party or parties from whom contribution may be
sought, but the omission so to notify such party or parties of any such service
shall not relieve the party from whom contribution may be sought from any
obligation it may have hereunder or otherwise (except as specifically provided
in Section 8(b)).

     9. TERMINATION. This Agreement may be terminated by you at any time prior
to the Closing Date by giving written notice to the Company if after the date of
this Agreement trading in the Common Stock shall have been suspended, or if
there shall have occurred (i) the engagement in hostilities or an escalation of
major hostilities by the United States or the declaration of war or a national
emergency by the United States on or after the date hereof, (ii) any outbreak of
hostilities or other national or international calamity or crisis or change in
economic or political conditions if the effect of such outbreak, calamity,
crisis or change in economic or political conditions in the financial markets of
the United States would, in the Underwriters' reasonable judgment, make the
offering or delivery of the Stock impracticable, (iii) suspension of trading in
securities generally or a material adverse change in value of securities
generally on the New York Stock Exchange, the American Stock Exchange, The
Nasdaq Stock Market, or limitations on prices (other than limitations on hours
or numbers of days of trading) for securities on either such exchange or system,
(iv) the enactment, publication, decree or other promulgation of any federal or
state statute, regulation, rule or order of, or commencement of any proceeding
or investigation by, any court, legislative body, agency or other governmental
authority which in the Underwriters' reasonable opinion materially and adversely
affects or will materially or adversely affect the business or operations of the
Company, (v) declaration of a banking moratorium by either federal or New York
State authorities or (vi) the taking of any action by any federal, state or
local government or agency in respect of its monetary or fiscal affairs, which
in the Underwriters' reasonable opinion has a material adverse effect on the
securities markets in the United States. If this Agreement shall be terminated
pursuant to this Section 9, there shall be no liability of the Company to the
Underwriters (or their respective control persons) and no liability of the
Underwriters to the Company (or its control persons); PROVIDED, HOWEVER, that in
the event of any such termination the Company agrees to indemnify and hold
harmless the Underwriters from all costs or expenses incident to the performance
of the obligations of the Company under this Agreement, including all costs and
expenses referred to in paragraphs (i), (j) and (k) of Section 6 hereof.

     10. CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The obligations of the several
Underwriters to purchase and pay for the Stock shall be subject to the
performance by the Company of all its obligations to be performed hereunder at
or prior to the Closing Date or any later date on which Option Stock is to be
purchased, as the case may be, and to the following further conditions:

          (a) The Registration Statement shall have become effective; and no
     stop order suspending the effectiveness thereof shall have been issued and
     no proceedings therefor shall be pending or threatened by the Commission.

          (b) The legality and sufficiency of the sale of the Stock hereunder
     and the validity and form of the certificates representing the Stock, all
     corporate proceedings and other legal matters incident to the foregoing,
     and the form of the Registration Statement and of the Prospectus (except as
     to the financial statements contained therein), shall have been presented,
     in a reasonably satisfactory form, at or prior to the Closing Date, to
     Davis Polk & Wardwell, counsel for the Underwriters.

          (c) You shall have received from Brobeck, Phleger & Harrison LLP,
     counsel for the Company, an opinion addressed to the Underwriters and dated
     the Closing Date, covering the matters set forth in Annex A hereto, and if
     Option Stock is purchased at any date after the Closing Date, additional
     opinions from each such counsel, addressed to the Underwriters and dated
     such later date, confirming that the statements expressed as of the Closing
     Date in such opinions remain valid as of such later date.

          (d) You shall be satisfied that (i) as of the Effective Date, the
     statements made in the Registration Statement and the Prospectus were true
     and correct and neither the Registration Statement nor the Prospectus
     omitted to state any material fact required to be stated therein or
     necessary in order to make the statements therein, in light of the
     circumstances under which they were made, respectively, not misleading,
     (ii) since the Effective Date, no event has occurred which should have been
     set forth in a supplement or amendment to the Prospectus which has not been
     set forth in such a supplement or amendment, (iii) since the respective
     dates as of which information is given in the Registration Statement in the
     form in which it originally became effective and the Prospectus contained
     therein, there has not been any Material Adverse Change or, to the
     knowledge of the Company, any development involving a prospective Material
     Adverse Change and, since such dates, except in the ordinary course of
     business, the Company has not entered into any material transaction not
     referred to in the Registration Statement in the form in which it
     originally became effective and the Prospectus contained therein,

     (iv) the Company does not have any material contingent obligations which
     are not disclosed in the Registration Statement and the Prospectus, (v)
     there are not any pending or, to the knowledge of the Company, threatened,
     legal proceedings to which the Company is a party or of which property of
     the Company is the subject which are material and which are not disclosed
     in the Registration Statement and the Prospectus, (vi) there are not any
     franchises, contracts, leases or other documents which are required to be
     filed as exhibits to the Registration Statement which have not been filed
     as required, (vii) the representations and warranties of the Company herein
     are true and correct in all material respects as of the Closing Date or any
     later date on which Option Stock is to be purchased, as the case may be,
     and (viii) there has not been any material change in the market for
     securities in general or in political, financial or economic conditions
     from those reasonably foreseeable as to render it impracticable in your
     reasonable judgment to make a public offering of the Stock, or a material
     adverse change in market levels for securities in general (or those of
     companies in particular) or financial or economic conditions which render
     it inadvisable to proceed.

          (e) You shall have received on the Closing Date and on any later date
     on which Option Stock is purchased a certificate, dated the Closing Date or
     such later date, as the case may be, and signed by the President and the

     of said certificate have carefully examined the Registration Statement in
     the form in which it originally became effective and the Prospectus
     contained therein and any supplements or amendments thereto, and that the
     statements included in clauses (i) through (vii) of paragraph (d) of this
     Section 10 are true and correct.

          (f) You shall have received from KPMG LLP, a letter or letters,

     on which Option Stock is purchased, confirming that they are independent
     public or certified public accountants with respect to the Company within
     the meaning of the Securities Act and the rules of the Commission
     thereunder and based upon the procedures described in their letter
     delivered to you concurrently with the execution of this Agreement (herein
     called the ORIGINAL LETTER), but carried out to a date not more than three
     business days prior to the Closing Date or such later date on which Option
     Stock is purchased (i) confirming, to the extent true, that the statements
     and conclusions set forth in the Original Letter are accurate as of the
     Closing Date or such later date, as the case may be, and (ii) setting forth
     any revisions and additions to the statements and conclusions set forth in
     the Original Letter which are necessary to reflect any changes in the facts
     described in the Original Letter since the date of the Original Letter or
     to reflect the availability of more recent financial statements, data or
     information. The letters shall not disclose


                                       27
<PAGE>

     any change, or any development involving a prospective change, in or
     affecting the business or properties of the Company which, in your sole
     judgment, makes it impractical or inadvisable to proceed with the public
     offering of the Stock or the purchase of the Option Stock as contemplated
     by the Prospectus.

          (g) You shall have been furnished evidence in usual written or
     telegraphic form from the appropriate authorities of the several

     employees and directors of the Company, and beneficial holders of any
     securities issued by the Company (other than Participants who (i) are not
     employees of the Company and (ii) do not otherwise hold securities issued
     by the Company) agreements, substantially in the forms attached hereto as
     Annexes B-1, B-2 or B-3, as applicable, each of which shall be in full
     force and effect on the Closing Date.

     All the agreements, opinions, certificates and letters mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if Davis Polk & Wardwell, counsel for the Underwriters,
shall be satisfied that they comply in form and scope.

     In case any of the conditions specified in this Section 10 shall not be
fulfilled, this Agreement may be terminated by you by giving notice to the
Company. Any such termination shall be without liability of the Company to the
Underwriters (or their respective control persons) and without liability of the
Underwriters to the Company (or its control persons); PROVIDED, HOWEVER, that
(i) in the event of such termination, the Company agrees to indemnify and hold
harmless the Underwriters from all costs or expenses incident to the performance
of the obligations of the Company under this Agreement, including all costs and
expenses referred to in paragraphs (i), (j) and (k) of Section 6 hereof, and
(ii) if this Agreement is terminated by you because of any refusal, inability or
failure on the part of the Company to perform any agreement herein, to fulfill
any of the conditions herein, or to comply with any provision hereof other than

the Underwriters severally upon demand for all out-of-pocket expenses (including

paragraph (a) of Sections 7 and 8 of this Agreement, notwithstanding the absence
of a judicial determination as to the propriety and enforceability of the

later be held to be improper; PROVIDED, HOWEVER, that (i) to the extent any such
payment is ultimately held to be improper, the persons receiving such payments
shall promptly refund them and (ii) such persons shall provide to the Company,
upon request, reasonable assurances of their ability to effect any refund, when

such purchaser, of any of the Stock from any of the several Underwriters.

                  Re:  LivePerson, Inc. Registration Statement on Form S-1
                       for 4,600,000 Shares of Common Stock

Ladies and Gentlemen:

                  We have acted as counsel to LivePerson, Inc., a Delaware
corporation (the "Company"), in connection with the proposed issuance and sale
by the Company of up to 4,600,000 shares of the Company's Common Stock (the
"Shares") pursuant to the Company's Registration Statement on Form S-1 (the
"Registration Statement") filed with the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the "Act").

                  This opinion is being furnished in accordance with the
requirements of Item 16(a) of Form S-1 and Item 601(b)(5)(i) of Regulation S-K.

                  We have reviewed the Company's charter documents and the
corporate proceedings taken by the Company in connection with the issuance and
sale of the Shares. Based on such review, we are of the opinion that the Shares
have been duly authorized, and if, as and when issued in accordance with the
Registration Statement and the related prospectus (as amended and supplemented
through the date of issuance) will be legally issued, fully paid and
non-assessable.

                  We consent to the filing of this opinion letter as Exhibit 5.1
to the Registration Statement and to the reference to this firm under the
caption "Legal Matters" in the prospectus which is part of the Registration
Statement. In giving this consent, we do not thereby admit that we are within
the category of persons whose consent is required under Section 7 of the Act,
the rules and regulations of the Securities and Exchange Commission promulgated
thereunder, or Item 509 of Regulation S-K.

                  Our opinion is expressly limited to the matters set forth
above and we render no opinion,

whether by implication or otherwise, as to any other matters relating to the
Company or the Shares.

                                             Very truly yours,

                                LIVEPERSON, INC.
                            2000 STOCK INCENTIVE PLAN

                                  ARTICLE ONE

                               GENERAL PROVISIONS

    I.   PURPOSE OF THE PLAN

         This 2000 Stock Incentive Plan is intended to promote the interests of
LivePerson, Inc., a Delaware corporation, by providing eligible persons with the
opportunity to acquire a proprietary interest, or otherwise increase their
proprietary interest, in the Corporation as an incentive for them to remain in
the service of the Corporation.

         Capitalized terms shall have the meanings assigned to such terms in the
attached Appendix.

         All share numbers reflect the 3-for-2 stock split of the Common Stock
which was effected on March 8, 2000.

    II.  STRUCTURE OF THE PLAN

         A.   The Plan shall be divided into five separate equity incentive
programs:

              (i)       the Discretionary Option Grant Program under which
    eligible persons may, at the discretion of the Plan Administrator, be
    granted options to purchase shares of Common Stock,

              (ii)      the Salary Investment Option Grant Program under which
    eligible employees may elect to have a portion of their base salary invested
    each year in special options,

              (iii)     the Stock Issuance Program under which eligible persons
    may, at the discretion of the Plan Administrator, be issued shares of Common
    Stock directly, either through the immediate purchase of such shares or as a
    bonus for services rendered the Corporation (or any Parent or Subsidiary),

              (iv)      the Automatic Option Grant Program under which eligible
    non-employee Board members shall automatically receive options at periodic
    intervals to purchase shares of Common Stock, and

              (v)       the Director Fee Option Grant Program under which
    non-employee Board members may elect to have all or any portion of their
    annual retainer fee otherwise payable in cash applied to a special option
    grant.


<PAGE>


         B.   The provisions of Articles One and Seven shall apply to all equity
programs under the Plan and shall govern the interests of all persons under the
Plan.

    III. ADMINISTRATION OF THE PLAN

         A.   Prior to the Section 12 Registration Date, the Discretionary
Option Grant and Stock Issuance Programs shall be administered by the Board
unless otherwise determined by the Board. Beginning with the Section 12
Registration Date, the following provisions shall govern the administration of
the Plan:

              (i)       The Board shall have the authority to administer the
    Discretionary Option Grant and Stock Issuance Programs with respect to
    Section 16 Insiders but may delegate such authority in whole or in part to
    the Primary Committee.

              (ii)      Administration of the Discretionary Option Grant and
    Stock Issuance Programs with respect to all other persons eligible to
    participate in those programs may, at the Board's discretion, be vested in
    the Primary Committee or a Secondary Committee, or the Board may retain the
    power to administer those programs with respect to all such persons.

              (iii)     The Board (or Primary Committee) shall select the
    Section 16 Insiders and other highly compensated Employees eligible to
    participate in the Salary Investment Option Grant Program. However, all
    option grants under the Salary Investment Option Grant Program shall be made
    in accordance with the terms of that program and the Primary Committee shall
    not exercise any administrative discretion with respect to option grants
    made under the program.

              (iv)      Administration of the Automatic Option Grant and
    Director Fee Option Grant Programs shall be self-executing in accordance
    with the terms of those programs.

         B.   Each Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full power and authority
subject to the provisions of the Plan:

              (i)       to establish such rules as it may deem appropriate for
    proper administration of the Plan, to make all factual determinations, to
    construe and interpret the provisions of the Plan and the awards thereunder
    and to resolve any and all ambiguities thereunder;

              (ii)      to determine, with respect to awards made under the
    Discretionary Option Grant and Stock Issuance Programs, which eligible
    persons are to receive such awards, the time or times when such awards are
    to be made, the number of shares to be covered by each such award, the
    vesting schedule (if any) applicable to the award, the status of a granted
    option as either an Incentive Option or a Non-Statutory Option and the
    maximum term for which the option is to remain outstanding;

              (iii)     to amend, modify or cancel any outstanding award with
    the consent of the holder or accelerate the vesting of such award; and

              (iv)      to take such other discretionary actions as permitted
    pursuant to the terms of the applicable program.

Decisions of each Plan Administrator within the scope of its administrative
functions under the Plan shall be final and binding on all parties.

         C.   Members of the Primary Committee or any Secondary Committee shall
serve for such period of time as the Board may determine and may be removed by
the Board at any time. The Board may also at any time terminate the functions of
any Secondary Committee and reassume all powers and authority previously
delegated to such committee.

         D.   Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee. No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any options or stock issuances under the Plan.

    IV.  ELIGIBILITY

         A.   The persons eligible to participate in the Discretionary Option
Grant and Stock Issuance Programs are as follows:

              (i)       Employees,

              (ii)      non-employee members of the Board or the board of
    directors of any Parent or Subsidiary, and

              (iii)     consultants and other independent advisors who provide
    services to the Corporation (or any Parent or Subsidiary).

         B.   Only Employees who are Section 16 Insiders or other highly
compensated individuals shall be eligible to participate in the Salary
Investment Option Grant Program.

         C.   Only non-employee Board members shall be eligible to participate
in the Automatic Option Grant and Director Fee Option Grant Programs.

    V.   STOCK SUBJECT TO THE PLAN

         A.   The stock issuable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock, including shares repurchased by the
Corporation on the open market. The maximum number of shares of Common Stock
initially reserved for issuance over the term of the Plan shall not exceed Ten
Million (10,000,000) shares. Such reserve shall consist of (i) the number of
shares estimated to remain available for issuance, as of the Section 12
Registration Date, under the Predecessor Plan, including the shares subject to
the outstanding options to be incorporated into the Plan and the additional
shares which would otherwise be available for future grant, plus (ii) an
increase of _____________________________


                                       3

<PAGE>


(____________) shares authorized by the Board subject to stockholder approval
prior to the Section 12 Registration Date.

         B.   The number of shares of Common Stock available for issuance under
the Plan shall automatically increase on the first trading day of January each
calendar year during the term of the Plan, beginning with the calendar year
2001, by an amount equal to three percent (3%) of the total number of shares of
Common Stock outstanding on the last trading day in December of the immediately
preceding calendar year, but in no event shall such annual increase exceed One
Million Five Hundred Thousand (1,500,000) shares.

         C.   No one person participating in the Plan may receive options,
separately exercisable stock appreciation rights and direct stock issuances for
more than Five Hundred Thousand (500,000) shares of Common Stock in the
aggregate per calendar year.

         D.   Shares of Common Stock subject to outstanding options (including
options incorporated into this Plan from the Predecessor Plan) shall be
available for subsequent issuance under the Plan to the extent those options
expire, terminate or are cancelled for any reason prior to exercise in full.
Unvested shares issued under the Plan and subsequently repurchased by the
Corporation, at the original exercise or issue price paid per share, pursuant to
the Corporation's repurchase rights under the Plan shall be added back to the
number of shares of Common Stock reserved for issuance under the Plan and shall
accordingly be available for reissuance through one or more subsequent options
or direct stock issuances under the Plan. However, should the exercise price of
an option under the Plan be paid with shares of Common Stock or should shares of
Common Stock otherwise issuable under the Plan be withheld by the Corporation in
satisfaction of the withholding taxes incurred in connection with the exercise
of an option or the vesting of a stock issuance under the Plan, then the number
of shares of Common Stock available for issuance under the Plan shall be reduced
by the gross number of shares for which the option is exercised or which vest
under the stock issuance, and not by the net number of shares of Common Stock
issued to the holder of such option or stock issuance. Shares of Common Stock
underlying one or more stock appreciation rights exercised under the Plan shall
NOT be available for subsequent issuance.

         E.   If any change is made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made to (i) the maximum number and/or class of securities issuable under the
Plan, (ii) the number and/or class of securities by which the share reserve is
to increase each calendar year pursuant to the automatic share increase
provisions of the Plan, (iii) the number and/or class of securities for which
any one person may be granted options, separately exercisable stock appreciation
rights and direct stock issuances under the Plan per calendar year, (iv) the
number and/or class of securities for which grants are subsequently to be made
under the Automatic Option Grant Program to new and continuing non-employee
Board members, (v) the number and/or class of securities and the exercise price
per share in effect under each outstanding option under the Plan and (vi) the
number and/or class of securities and price per share in effect under each
outstanding option incorporated into this Plan from the Predecessor Plan. Such
adjustments to the outstanding options are to be effected in a manner


                                       4

<PAGE>


which shall preclude the enlargement or dilution of rights and benefits under
such options. The adjustments determined by the Plan Administrator shall be
final, binding and conclusive.

                                  ARTICLE TWO

                       DISCRETIONARY OPTION GRANT PROGRAM

    I.   OPTION TERMS

         Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; PROVIDED, however, that each such document
shall comply with the terms specified below. Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

         A.   EXERCISE PRICE.

              1.   The exercise price per share shall be fixed by the Plan
Administrator at the time of the option grant and may be less than, equal to or
greater than the Fair Market Value per share of Common Stock on the option grant
date.

              2.   The exercise price shall become immediately due upon exercise
of the option and shall, subject to the provisions of Section II of Article
Seven and the documents evidencing the option, be payable in one or more of the
following forms:

                   (i)       in cash or check made payable to the Corporation;

                   (ii)      shares of Common Stock held for the requisite
    period necessary to avoid a charge to the Corporation's earnings for
    financial reporting purposes and valued at Fair Market Value on the Exercise
    Date, or

                   (iii)     to the extent the option is exercised for vested
    shares, through a special sale and remittance procedure pursuant to which
    the Optionee shall concurrently provide irrevocable instructions to (a) a
    Corporation-designated brokerage firm to effect the immediate sale of the
    purchased shares and remit to the Corporation, out of the sale proceeds
    available on the settlement date, sufficient funds to cover the aggregate
    exercise price payable for the purchased shares plus all applicable Federal,
    state and local income and employment taxes required to be withheld by the
    Corporation by reason of such exercise and (b) the Corporation to deliver
    the certificates for the purchased shares directly to such brokerage firm in
    order to complete the sale.

         Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

         B.   EXERCISE AND TERM OF OPTIONS. Each option shall be exercisable at
such time or times, during such period and for such number of shares as shall be
determined by the Plan Administrator and set forth in the documents evidencing
the option. However, no option shall have a term in excess of ten (10) years
measured from the option grant date.


                                       6

<PAGE>


         C.   CESSATION OF SERVICE.

              1.   The following provisions shall govern the exercise of any
options outstanding at the time of the Optionee's cessation of Service or death:

                   (i)       Any option outstanding at the time of the
    Optionee's cessation of Service for any reason shall remain exercisable for
    such period of time thereafter as shall be determined by the Plan
    Administrator and set forth in the documents evidencing the option, but no
    such option shall be exercisable after the expiration of the option term.

                   (ii)      Any option exercisable in whole or in part by the
    Optionee at the time of death may be subsequently exercised by his or her
    Beneficiary.

                   (iii)     During the applicable post-Service exercise period,
    the option may not be exercised in the aggregate for more than the number of
    vested shares for which the option is exercisable on the date of the
    Optionee's cessation of Service. Upon the expiration of the applicable
    exercise period or (if earlier) upon the expiration of the option term, the
    option shall terminate and cease to be outstanding for any vested shares for
    which the option has not been exercised. However, the option shall,
    immediately upon the Optionee's cessation of Service, terminate and cease to
    be outstanding to the extent the option is not otherwise at that time
    exercisable for vested shares.

                   (iv)      Should the Optionee's Service be terminated for
    Misconduct or should the Optionee engage in Misconduct while his or her
    options are outstanding, then all such options shall terminate immediately
    and cease to be outstanding.

              2.   The Plan Administrator shall have complete discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding:

                   (i)       to extend the period of time for which the option
    is to remain exercisable following the Optionee's cessation of Service to
    such period of time as the Plan Administrator shall deem appropriate, but
    in no event beyond the expiration of the option term, and/or

                   (ii)      to permit the option to be exercised, during the
    applicable post-Service exercise period, for one or more additional
    installments in which the Optionee would have vested had the Optionee
    continued in Service.

         D.   STOCKHOLDER RIGHTS. The holder of an option shall have no
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

         E.   REPURCHASE RIGHTS. The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of Common
Stock. Should the Optionee cease Service while holding such unvested shares, the
Corporation shall have the right to


                                       7

<PAGE>


repurchase, at the exercise price paid per share, any or all of those unvested
shares. The terms upon which such repurchase right shall be exercisable
(including the period and procedure for exercise and the appropriate vesting
schedule for the purchased shares) shall be established by the Plan
Administrator and set forth in the document evidencing such repurchase right.

         F.   LIMITED TRANSFERABILITY OF OPTIONS. During the lifetime of the
Optionee, Incentive Options shall be exercisable only by the Optionee and shall
not be assignable or transferable other than by will or by the laws of
inheritance following the Optionee's death. Non-Statutory Options shall be
subject to the same restrictions, except that a Non-Statutory Option may, to the
extent permitted by the Plan Administrator, be assigned in whole or in part
during the Optionee's lifetime (i) as a gift to one or more members of the
Optionee's immediate family, to a trust in which Optionee and/or one or more
such family members hold more than fifty percent (50%) of the beneficial
interest or to an entity in which more than fifty percent (50%) of the voting
interests are owned by one or more such family members or (ii) pursuant to a
domestic relations order. The terms applicable to the assigned portion shall be
the same as those in effect for the option immediately prior to such assignment
and shall be set forth in such documents issued to the assignee as the Plan
Administrator may deem appropriate.

         Notwithstanding the foregoing, the Optionee may also designate one or
more persons as the beneficiary or beneficiaries of his or her outstanding
options, and those options shall, in accordance with such designation,
automatically be transferred to such beneficiary or beneficiaries upon the
Optionee's death while holding those options. Such beneficiary or beneficiaries
shall take the transferred options subject to all the terms and conditions of
the applicable agreement evidencing each such transferred option, including
(without limitation) the limited time period during which the option may be
exercised following the Optionee's death.

    II.  INCENTIVE OPTIONS

         The terms specified below shall be applicable to all Incentive Options.
Except as modified by the provisions of this Section II, all the provisions of
Articles One, Two and Six shall be applicable to Incentive Options. Options
which are specifically designated as Non-Statutory Options when issued under the
Plan shall NOT be subject to the terms of this Section II.

         A.   ELIGIBILITY. Incentive Options may only be granted to Employees.

         B.   EXERCISE PRICE. The exercise price per share shall not be less
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

         C.   DOLLAR LIMITATION. The aggregate Fair Market Value of the shares
of Common Stock (determined as of the respective date or dates of grant) for
which one or more options granted to any Employee under the Plan (or any other
option plan of the Corporation or any Parent or Subsidiary) may for the first
time become exercisable as Incentive Options during any one calendar year shall
not exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the
Employee holds two (2) or more such options which become exercisable for the
first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.


                                       8

<PAGE>


         D.   10% STOCKHOLDER. If any Employee to whom an Incentive Option is
granted is a 10% Stockholder, then the exercise price per share shall not be
less than one hundred ten percent (110%) of the Fair Market Value per share of
Common Stock on the option grant date, and the option term shall not exceed five
(5) years measured from the option grant date.

    III. CHANGE IN CONTROL/HOSTILE TAKE-OVER

         A.   Each option outstanding at the time of a Change in Control but not
otherwise fully-vested shall automatically accelerate so that each such option
shall, immediately prior to the effective date of the Change in Control, become
exercisable for all of the shares of Common Stock at the time subject to that
option and may be exercised for any or all of those shares as fully-vested
shares of Common Stock. However, an outstanding option shall not so accelerate
if and to the extent: (i) such option is, in connection with the Change in
Control, assumed or otherwise continued in full force and effect by the
successor corporation (or parent thereof) pursuant to the terms of the Change in
Control, (ii) such option is replaced with a cash incentive program of the
successor corporation which preserves the spread existing at the time of the
Change in Control on the shares of Common Stock for which the option is not
otherwise at that time exercisable and provides for subsequent payout in
accordance with the same vesting schedule applicable to those option shares or
(iii) the acceleration of such option is subject to other limitations imposed by
the Plan Administrator at the time of the option grant. Each option outstanding
at the time of the Change in Control shall terminate as provided in Section
III.C. of this Article Two.

         B.   All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Change in Control, except to
the extent: (i) those repurchase rights are assigned to the successor
corporation (or parent thereof) or otherwise continue in full force and effect
pursuant to the terms of the Change in Control or (ii) such accelerated vesting
is precluded by other limitations imposed by the Plan Administrator at the time
the repurchase right is issued.

         C.   Immediately following the consummation of the Change in Control,
all outstanding options shall terminate and cease to be outstanding, except to
the extent assumed by the successor corporation (or parent thereof) or otherwise
expressly continued in full force and effect pursuant to the terms of the Change
in Control.

         D.   Each option which is assumed in connection with a Change in
Control shall be appropriately adjusted, immediately after such Change in
Control, to apply to the number and class of securities which would have been
issuable to the Optionee in consummation of such Change in Control had the
option been exercised immediately prior to such Change in Control. Appropriate
adjustments to reflect such Change in Control shall also be made to (i) the
exercise price payable per share under each outstanding option, PROVIDED the
aggregate exercise price payable for such securities shall remain the same, (ii)
the maximum number and/or class of securities available for issuance over the
remaining term of the Plan and (iii) the maximum number and/or class of
securities for which any one person may be granted options, separately
exercisable stock appreciation rights and direct stock issuances under the Plan
per calendar year. To the extent the actual holders of the Corporation's
outstanding Common Stock receive cash consideration for their Common Stock in
consummation of the Change in Control, the successor


                                       9

<PAGE>


corporation may, in connection with the assumption of the outstanding options,
substitute one or more shares of its own common stock with a fair market value
equivalent to the cash consideration paid per share of Common Stock in such
Change in Control.

         E.   The Plan Administrator may at any time provide that one or more
options will automatically accelerate in connection with a Change in Control,
whether or not those options are assumed or otherwise continued in full force
and effect pursuant to the terms of the Change in Control. Any such option shall
accordingly become exercisable, immediately prior to the effective date of such
Change in Control, for all of the shares of Common Stock at the time subject to
that option and may be exercised for any or all of those shares as fully-vested
shares of Common Stock. In addition, the Plan Administrator may at any time
provide that one or more of the Corporation's repurchase rights shall not be
assignable in connection with such Change in Control and shall terminate upon
the consummation of such Change in Control.

         F.   The Plan Administrator may at any time provide that one or more
options will automatically accelerate upon an Involuntary Termination of the
Optionee's Service within a designated period (not to exceed eighteen (18)
months) following the effective date of any Change in Control in which those
options do not otherwise accelerate. Any options so accelerated shall remain
exercisable for fully-vested shares until the EARLIER of (i) the expiration of
the option term or (ii) the expiration of the one (1) year period measured from
the effective date of the Involuntary Termination. In addition, the Plan
Administrator may at any time provide that one or more of the Corporation's
repurchase rights shall immediately terminate upon such Involuntary Termination.

         G.   The Plan Administrator may at any time provide that one or more
options will automatically accelerate in connection with a Hostile Take-Over.
Any such option shall become exercisable, immediately prior to the effective
date of such Hostile Take-Over, for all of the shares of Common Stock at the
time subject to that option and may be exercised for any or all of those shares
as fully-vested shares of Common Stock. In addition, the Plan Administrator may
at any time provide that one or more of the Corporation's repurchase rights
shall terminate automatically upon the consummation of such Hostile Take-Over.
Alternatively, the Plan Administrator may condition such automatic acceleration
and termination upon an Involuntary Termination of the Optionee's Service within
a designated period (not to exceed eighteen (18) months) following the effective
date of such Hostile Take-Over. Each option so accelerated shall remain
exercisable for fully-vested shares until the expiration or sooner termination
of the option term.

         H.   The portion of any Incentive Option accelerated in connection with
a Change in Control or Hostile Take Over shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
($100,000) limitation is not exceeded. To the extent such dollar limitation is
exceeded, the accelerated portion of such option shall be exercisable as a
Non-Statutory Option under the Federal tax laws.

    IV.  STOCK APPRECIATION RIGHTS

         The Plan Administrator may, subject to such conditions as it may
determine, grant to selected Optionees stock appreciation rights which will
allow the holders of those rights to


                                       10

<PAGE>


elect between the exercise of the underlying option for shares of Common Stock
and the surrender of that option in exchange for a distribution from the
Corporation in an amount equal to the excess of (a) the Option Surrender Value
of the number of shares for which the option is surrendered over (b) the
aggregate exercise price payable for such shares. The distribution may be made
in shares of Common Stock valued at Fair Market Value on the option surrender
date, in cash, or partly in shares and partly in cash, as the Plan Administrator
shall in its sole discretion deem appropriate.


                                       11

                                 ARTICLE THREE

                     SALARY INVESTMENT OPTION GRANT PROGRAM

    I.   OPTION GRANTS

         The Primary Committee may implement the Salary Investment Option Grant
Program for one or more calendar years beginning after the Underwriting Date and
select the Section 16 Insiders and other highly compensated Employees eligible
to participate in the Salary Investment Option Grant Program for each such
calendar year. Each selected individual who elects to participate in the Salary
Investment Option Grant Program must, prior to the start of each calendar year
of participation, file with the Plan Administrator (or its designate) an
irrevocable authorization directing the Corporation to reduce his or her base
salary for that calendar year by an amount not less than Five Thousand Dollars
($5,000) nor more than Fifty Thousand Dollars ($50,000). Each individual who
files such a timely election shall be granted an option under the Salary
Investment Grant Program on the first trading day in January for the calendar
year for which the salary reduction is to be in effect.

    II.  OPTION TERMS

         Each option shall be a Non-Statutory Option evidenced by one or more
documents in the form approved by the Plan Administrator; PROVIDED, however,
that each such document shall comply with the terms specified below.

         A.   EXERCISE PRICE.

              1.   The exercise price per share shall be thirty-three and
one-third percent (33-1/3%) of the Fair Market Value per share of Common Stock
on the option grant date.

              2.   The exercise price shall become immediately due upon exercise
of the option and shall be payable in one or more of the alternative forms
authorized under the Discretionary Option Grant Program. Except to the extent
the sale and remittance procedure specified thereunder is utilized, payment of
the exercise price for the purchased shares must be made on the Exercise Date.

         B.   NUMBER OF OPTION SHARES. The number of shares of Common Stock
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

              X = A / (B x 66-2/3%), where

              X is the number of option shares,

              A is the dollar amount of the approved reduction in
         the Optionee's base salary for the calendar year, and


                                       12

<PAGE>



              B is the Fair Market Value per share of Common Stock
         on the option grant date.

         C.   EXERCISE AND TERM OF OPTIONS. The option shall become exercisable
in a series of twelve (12) successive equal monthly installments upon the
Optionee's completion of each calendar month of Service in the calendar year for
which the salary reduction is in effect. Each option shall have a maximum term
of ten (10) years measured from the option grant date.

         D.   CESSATION OF SERVICE. Each option outstanding at the time of the
Optionee's cessation of Service shall remain exercisable, for any or all of the
shares for which the option is exercisable at the time of such cessation of
Service, until the EARLIER of (i) the expiration of the option term or (ii) the
expiration of the three (3)-year period following the Optionee's cessation of
Service. To the extent the option is held by the Optionee at the time of his or
her death, the option may be exercised by his or her Beneficiary. However, the
option shall, immediately upon the Optionee's cessation of Service, terminate
and cease to remain outstanding with respect to any and all shares of Common
Stock for which the option is not otherwise at that time exercisable.

    III. CHANGE IN CONTROL/HOSTILE TAKE-OVER

         A.   In the event of any Change in Control or Hostile Take-Over while
the Optionee remains in Service, each outstanding option shall automatically
accelerate so that each such option shall, immediately prior to the effective
date of the Change in Control or Hostile Take-Over, become fully exercisable
with respect to the total number of shares of Common Stock at the time subject
to such option and may be exercised for any or all of those shares as
fully-vested shares of Common Stock. Each such option accelerated in connection
with a Change in Control shall terminate upon the Change in Control, except to
the extent assumed by the successor corporation (or parent thereof) or otherwise
continued in full force and effect pursuant to the terms of the Change in
Control. Each such option accelerated in connection with a Hostile Take-Over
shall remain exercisable until the expiration or sooner termination of the
option term.

         B.   Each option which is assumed in connection with a Change in
Control shall be appropriately adjusted to apply to the number and class of
securities which would have been issuable to the Optionee in consummation of
such Change in Control had the option been exercised immediately prior to such
Change in Control. Appropriate adjustments shall also be made to the exercise
price payable per share under each outstanding option, PROVIDED the aggregate
exercise price payable for such securities shall remain the same. To the extent
the actual holders of the Corporation's outstanding Common Stock receive cash
consideration for their Common Stock in consummation of the Change in Control,
the successor corporation may, in connection with the assumption of the
outstanding options, substitute one or more shares of its own common stock with
a fair market value equivalent to the cash consideration paid per share of
Common Stock in such Change in Control.

         C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding options. The Optionee shall in return be entitled to a
cash distribution from the Corporation in an


                                       13

<PAGE>


amount equal to the excess of (i) the Option Surrender Value of the shares of
Common Stock at the time subject to each surrendered option (whether or not the
Optionee is otherwise at the time vested in those shares) over (ii) the
aggregate exercise price payable for such shares. Such cash distribution shall
be paid within five (5) days following the surrender of the option to the
Corporation.

    IV.  REMAINING TERMS

         The remaining terms of each option granted under the Salary Investment
Option Grant Program shall be the same as the terms in effect for options made
under the Discretionary Option Grant Program.

                             STOCK ISSUANCE PROGRAM

    I.   STOCK ISSUANCE TERMS

         Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening options. Shares
of Common Stock may also be issued under the Stock Issuance Program pursuant to
share right awards which entitle the recipients to receive those shares upon the
attainment of designated performance goals or Service requirements. Each such
award shall be evidenced by one or more documents which comply with the terms
specified below.

         A.   PURCHASE PRICE.

              1.   The purchase price per share of Common Stock subject to
direct issuance shall be fixed by the Plan Administrator and may be less than,
equal to or greater than the Fair Market Value per share of Common Stock on the
issue date.

              2.   Subject to the provisions of Section II of Article Seven,
shares of Common Stock may be issued under the Stock Issuance Program for any of
the following items of consideration which the Plan Administrator may deem
appropriate in each individual instance:

                   (i)   cash or check made payable to the Corporation, or

                   (ii)  past services rendered to the Corporation (or any
    Parent or Subsidiary).

         B.   VESTING/ISSUANCE PROVISIONS.

              1.   The Plan Administrator may issue shares of Common Stock which
are fully and immediately vested upon issuance or which are to vest in one or
more installments over the Participant's period of Service or upon attainment of
specified performance objectives. Alternatively, the Plan Administrator may
issue share right awards which shall entitle the recipient to receive a
specified number of vested shares of Common Stock upon the attainment of one or
more performance goals or Service requirements established by the Plan
Administrator.

              2.   Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to his or her unvested
shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the Participant's unvested shares of Common Stock and
(ii) such escrow arrangements as the Plan Administrator shall deem appropriate.


                                       15

<PAGE>


              3.   The Participant shall have full stockholder rights with
respect to the issued shares of Common Stock, whether or not the Participant's
interest in those shares is vested. Accordingly, the Participant shall have the
right to vote such shares and to receive any regular cash dividends paid on such
shares.

              4.   Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock, or should the performance
objectives not be attained with respect to one or more such unvested shares of
Common Stock, then those shares shall be immediately surrendered to the
Corporation for cancellation, and the Participant shall have no further
stockholder rights with respect to those shares. To the extent the surrendered
shares were previously issued to the Participant for consideration paid in cash
or cash equivalent (including the Participant's purchase-money indebtedness),
the Corporation shall repay to the Participant the cash consideration paid for
the surrendered shares and shall cancel the unpaid principal balance of any
outstanding purchase-money note of the Participant attributable to the
surrendered shares.

              5.   The Plan Administrator may waive the surrender and
cancellation of one or more unvested shares of Common Stock (or other assets
attributable thereto) which would otherwise occur upon the cessation of the
Participant's Service or the non-attainment of the performance objectives
applicable to those shares. Such waiver shall result in the immediate vesting of
the Participant's interest in the shares of Common Stock as to which the waiver
applies. Such waiver may be effected at any time, whether before or after the
Participant's cessation of Service or the attainment or non-attainment of the
applicable performance objectives.

              6.   Outstanding share right awards shall automatically terminate,
and no shares of Common Stock shall actually be issued in satisfaction of those
awards, if the performance goals or Service requirements established for such
awards are not attained. The Plan Administrator, however, shall have the
authority to issue shares of Common Stock in satisfaction of one or more
outstanding share right awards as to which the designated performance goals or
Service requirements are not attained.

    II.  CHANGE IN CONTROL/HOSTILE TAKE-OVER

         A.   All of the Corporation's outstanding repurchase rights shall
terminate automatically, and all the shares of Common Stock subject to those
terminated rights shall immediately vest in full, in the event of any Change in
Control, except to the extent (i) those repurchase rights are assigned to the
successor corporation (or parent thereof) or otherwise continue in full force
and effect pursuant to the terms of the Change in Control or (ii) such
accelerated vesting is precluded by other limitations imposed by the Plan
Administrator at the time the repurchase right is issued.

         B.   The Plan Administrator may at any time provide for the automatic
termination of one or more of those outstanding repurchase rights and the
immediate vesting of the shares of Common Stock subject to those terminated
rights upon (i) a Change in Control or Hostile Take-Over or (ii) an Involuntary
Termination of the Participant's Service within a designated period (not to
exceed eighteen (18) months) following the effective date of any


                                       16

<PAGE>


Change in Control or Hostile Take-Over in which those repurchase rights are
assigned to the successor corporation (or parent thereof) or otherwise continue
in full force and effect.

    III. SHARE ESCROW/LEGENDS

         Unvested shares may, in the Plan Administrator's discretion, be held in
escrow by the Corporation until the Participant's interest in such shares vests
or may be issued directly to the Participant with restrictive legends on the
certificates evidencing those unvested shares.

                                  ARTICLE FIVE

                         AUTOMATIC OPTION GRANT PROGRAM

    I.   OPTION TERMS

         A.   GRANT DATES. Options shall be made on the dates specified below:

              1.   Each individual who is first elected or appointed as a
non-employee Board member at any time after the Underwriting Date shall
automatically be granted, on the date of such initial election or appointment, a
Non-Statutory Option to purchase Fifteen Thousand (15,000) shares of Common
Stock, provided that individual has not previously been in the employ of the
Corporation (or any Parent or Subsidiary).

              2.   On the date of each Annual Stockholders Meeting beginning
with the 2001 Annual Stockholder Meeting, each individual who is to continue to
serve as a non-employee Board member shall automatically be granted a
Non-Statutory Option to purchase Five Thousand (5,000) shares of Common Stock,
provided that individual has served as a non-employee Board member for at least
six (6) months.

         B.   EXERCISE PRICE.

              1.   The exercise price per share shall be equal to one hundred
percent (100%) of the Fair Market Value per share of Common Stock on the option
grant date.

              2.   The exercise price shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

         C.   OPTION TERM. Each option shall have a term of ten (10) years
measured from the option grant date.

         D.   EXERCISE AND VESTING OF OPTIONS. Each option shall be immediately
exercisable for any or all of the option shares. However, any unvested shares
purchased under the option shall be subject to repurchase by the Corporation, at
the exercise price paid per share, upon the Optionee's cessation of Board
service prior to vesting in those shares. Each initial 15,000-share option shall
vest, and the Corporation's repurchase right shall lapse, in a series of three
(3) successive equal annual installments over the Optionee's period of continued
service as a Board member, with the first such installment to vest upon the
Optionee's completion of one (1) year of Board service measured from the option
grant date. Each annual 5,000-share option shall vest, and the Corporation's
repurchase right shall lapse, upon the Optionee's completion of one (1) year of
Board service measured from the option grant date.


                                       18

<PAGE>


         E.   CESSATION OF BOARD SERVICE. The following provisions shall govern
the exercise of any options outstanding at the time of the Optionee's cessation
of Board service:

                   (i)       Any option outstanding at the time of the
    Optionee's cessation of Board service for any reason shall remain
    exercisable for a twelve (12)-month period following the date of such
    cessation of Board service, but in no event shall such option be exercisable
    after the expiration of the option term.

                   (ii)      Any option exercisable in whole or in part by the
    Optionee at the time of death may be subsequently exercised by his or her
    Beneficiary.

                   (iii)     Following the Optionee's cessation of Board
    service, the option may not be exercised in the aggregate for more than the
    number of shares for which the option was exercisable on the date of such
    cessation of Board service. Upon the expiration of the applicable exercise
    period or (if earlier) upon the expiration of the option term, the option
    shall terminate and cease to be outstanding for any vested shares for which
    the option has not been exercised. However, the option shall, immediately
    upon the Optionee's cessation of Board service, terminate and cease to be
    outstanding for any and all shares for which the option is not otherwise at
    that time exercisable.

                   (iv)      However, should the Optionee cease to serve as a
    Board member by reason of death or Permanent Disability, then all shares at
    the time subject to the option shall immediately vest so that such option
    may, during the twelve (12)-month exercise period following such cessation
    of Board service, be exercised for all or any portion of those shares as
    fully-vested shares of Common Stock.

    II.  CHANGE IN CONTROL/HOSTILE TAKE-OVER

         A.   In the event of any Change in Control or Hostile Take-Over, the
shares of Common Stock at the time subject to each outstanding option but not
otherwise vested shall automatically vest in full so that each such option may,
immediately prior to the effective date of such Change in Control or Hostile
Take-Over, became fully exercisable for all of the shares of Common Stock at the
time subject to such option and maybe exercised for all or any of those shares
as fully-vested shares of Common Stock. Each such option accelerated in
connection with a Change in Control shall terminate upon the Change in Control,
except to the extent assumed by the successor corporation (or parent thereof) or
otherwise continued in full force and effect pursuant to the terms of the Change
in Control. Each such option accelerated in connection with a Hostile Take-Over
shall remain exercisable until the expiration or sooner termination of the
option term.

         B.   All outstanding repurchase rights shall automatically terminate
and the shares of Common Stock subject to those terminated rights shall
immediately vest in full, in the event of any Change in Control or Hostile
Take-Over.

         C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding options. The Optionee shall in return be entitled to a
cash distribution from the Corporation in an amount equal to the excess of (i)
the Option Surrender Value of the shares of Common Stock at


                                       19

<PAGE>


the time subject to each surrendered option (whether or not the option is
otherwise at the time exercisable for those shares) over (ii) the aggregate
exercise price payable for such shares. Such cash distribution shall be paid
within five (5) days following the surrender of the option to the Corporation.

         D.   Each option which is assumed in connection with a Change in
Control shall be appropriately adjusted to apply to the number and class of
securities which would have been issuable to the Optionee in consummation of
such Change in Control had the option been exercised immediately prior to such
Change in Control. Appropriate adjustments shall also be made to the exercise
price payable per share under each outstanding option, PROVIDED the aggregate
exercise price payable for such securities shall remain the same. To the extent
the actual holders of the Corporation's outstanding Common Stock receive cash
consideration for their Common Stock in consummation of the Change in Control,
the successor corporation may, in connection with the assumption of the
outstanding options, substitute one or more shares of its own common stock with
a fair market value equivalent to the cash consideration paid per share of
Common Stock in such Change in Control.

    III. REMAINING TERMS

         The remaining terms of each option granted under the Automatic Option
Grant Program shall be the same as the terms in effect for options made under
the Discretionary Option Grant Program.

                                  ARTICLE SIX

                        DIRECTOR FEE OPTION GRANT PROGRAM

    I.   OPTION GRANTS

         The Board may implement the Director Fee Option Grant Program as of the
first day of any calendar year beginning after the Underwriting Date. Upon such
implementation of the Program, each non-employee Board member may elect to apply
all or any portion of the annual retainer fee otherwise payable in cash for his
or her service on the Board to the acquisition of a special option grant under
this Director Fee Option Grant Program. Such election must be filed with the
Corporation's Chief Financial Officer prior to the first day of the calendar
year for which the election is to be in effect. Each non-employee Board member
who files such a timely election with respect to the annul retainer fee shall
automatically be granted an option under this Director Fee Option Grant Program
on the first trading day in January in the calendar year for which that fee
would otherwise be payable.

    II.  OPTION TERMS

         Each option shall be a Non-Statutory Option governed by the terms and
conditions specified below.

         A.   EXERCISE PRICE.

              1.   The exercise price per share shall be thirty-three and
one-third percent (33-1/3%) of the Fair Market Value per share of Common Stock
on the option grant date.

              2.   The exercise price shall become immediately due upon exercise
of the option and shall be payable in one or more of the alternative forms
authorized under the Discretionary Option Grant Program. Except to the extent
the sale and remittance procedure specified thereunder is utilized, payment of
the exercise price for the purchased shares must be made on the Exercise Date.

         B.   NUMBER OF OPTION SHARES. The number of shares of Common Stock
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

              X = A / (B x 66-2/3%), where

              X is the number of option shares,

              A is the portion of the annual retainer fee subject
         to the non-employee Board member's election, and

              B is the Fair Market Value per share of Common Stock
         on the option grant date.


                                       21

<PAGE>


         C.   EXERCISE AND TERM OF OPTIONS. The option shall become exercisable
in a series of twelve (12) successive equal monthly installments upon the
Optionee's completion of each month of Board service during the calendar year in
which the option is granted. Each option shall have a maximum term of ten (10)
years measured from the option grant date.

         D.   CESSATION OF BOARD SERVICE. Should the Optionee cease Board
service for any reason (other than death or Permanent Disability) while holding
one or more options, then each such option shall remain exercisable, for any or
all of the shares for which the option is exercisable at the time of such
cessation of Board service, until the EARLIER of (i) the expiration of the ten
(10)-year option term or (ii) the expiration of the three (3)-year period
measured from the date of such cessation of Board service. However, each option
held by the Optionee at the time of such cessation of Board service shall
immediately terminate and cease to remain outstanding with respect to any and
all shares of Common Stock for which the option is not otherwise at that time
exercisable.

         E.   DEATH OR PERMANENT DISABILITY. Should the Optionee's service as a
Board member cease by reason of death or Permanent Disability, then each option
held by such Optionee shall immediately become exercisable for all the shares of
Common Stock at the time subject to that option, and the option may be exercised
for any or all of those shares as fully-vested shares until the EARLIER of (i)
the expiration of the ten (10)-year option term or (ii) the expiration of the
three (3)-year period measured from the date of such cessation of Board service.

         Should the Optionee die after cessation of Board service but while
holding one or more options, then each such option may be exercised, for any or
all of the shares for which the option is exercisable at the time of the
Optionee's cessation of Board service (less any shares subsequently purchased by
Optionee prior to death), by the Optionee's Beneficiary. Such right of exercise
shall lapse, and the option shall terminate, upon the EARLIER of (i) the
expiration of the ten (10)-year option term or (ii) the three (3)-year period
measured from the date of the Optionee's cessation of Board service.

    III. CHANGE IN CONTROL/HOSTILE TAKE-OVER

         A.   In the event of any Change in Control or Hostile Take-Over while
the Optionee remains in Board service, each outstanding option held by such
Optionee shall automatically accelerate so that each such option shall,
immediately prior to the effective date of the Change in Control or Hostile
Take-Over, become fully exercisable with respect to the total number of shares
of Common Stock at the time subject to such option and may be exercised for any
or all of those shares as fully-vested shares of Common Stock. Each such option
accelerated in connection with a Change in Control shall terminate upon the
Change in Control, except to the extent assumed by the successor corporation (or
parent thereof) or otherwise expressly continued in full force and effect
pursuant to the terms of the Change in Control. Each such option accelerated in
connection with a Hostile Take-Over shall remain exercisable until the
expiration or sooner termination of the option term.

         B.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding options. The Optionee shall in return be entitled to a
cash distribution from the Corporation in an


                                       22

<PAGE>


amount equal to the excess of (i) the Option Surrender Value of the shares of
Common Stock at the time subject to each surrendered option (whether or not the
Optionee is otherwise at the time vested in those shares) over (ii) the
aggregate exercise price payable for such shares. Such cash distribution shall
be paid within five (5) days following the surrender of the option to the
Corporation.

         C.   Each option which is assumed in connection with a Change in
Control shall be appropriately adjusted, immediately after such Change in
Control, to apply to the number and class of securities which would have been
issuable to the Optionee in consummation of such Change in Control had the
option been exercised immediately prior to such Change in Control. Appropriate
adjustments shall also be made to the exercise price payable per share under
each outstanding option, PROVIDED the aggregate exercise price payable for such
securities shall remain the same. To the extent the actual holders of the
Corporation's outstanding Common Stock receive cash consideration for their
Common Stock in consummation of the Change in Control, the successor corporation
may, in connection with the assumption of the outstanding options under the
Director Fee Option Grant Program, substitute one or more shares of its own
common stock with a fair market value equivalent to the cash consideration paid
per share of Common Stock in such Change in Control.

    IV.  REMAINING TERMS

         The remaining terms of each option granted under this Director Fee
Option Grant Program shall be the same as the terms in effect for options made
under the Discretionary Option Grant Program.

                                  MISCELLANEOUS

    I.   NO IMPAIRMENT OF AUTHORITY

         Outstanding awards shall in no way affect the right of the Corporation
to adjust, reclassify, reorganize or otherwise change its capital or business
structure or to merge, consolidate, dissolve, liquidate or sell or transfer all
or any part of its business or assets.

    II.  FINANCING

         The Plan Administrator may permit any Optionee or Participant to pay
the option exercise price under the Discretionary Option Grant Program or the
purchase price of shares issued under the Stock Issuance Program by delivering a
full-recourse, interest bearing promissory note payable in one or more
installments. The terms of any such promissory note (including the interest rate
and the terms of repayment) shall be established by the Plan Administrator in
its sole discretion. In no event may the maximum credit available to the
Optionee or Participant exceed the sum of (i) the aggregate option exercise
price or purchase price payable for the purchased shares (less the par value of
such shares) plus (ii) any Federal, state and local income and employment tax
liability incurred by the Optionee or the Participant in connection with the
option exercise or share purchase.

    III. TAX WITHHOLDING

         A.   The Corporation's obligation to deliver shares of Common Stock
upon the exercise of options or the issuance or vesting of such shares under the
Plan shall be subject to the satisfaction of all applicable Federal, state and
local income and employment tax withholding requirements.

         B.   The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
Plan with the right to use shares of Common Stock in satisfaction of all or part
of the Withholding Taxes incurred by such holders in connection with the
exercise of their options or the vesting of their shares. Such right may be
provided to any such holder in either or both of the following formats:

              STOCK WITHHOLDING: The election to have the Corporation withhold,
from the shares of Common Stock otherwise issuable upon the exercise of such
Non-Statutory Option or the vesting of such shares, a portion of those shares
with an aggregate Fair Market Value equal to the percentage of the Withholding
Taxes (not to exceed one hundred percent (100%)) designated by the holder.

              STOCK DELIVERY: The election to deliver to the Corporation, at the
time the Non-Statutory Option is exercised or the shares vest, one or more
shares of Common Stock previously acquired by such holder (other than in
connection with the option exercise or share vesting triggering the Withholding
Taxes) with an aggregate Fair Market Value equal to the percentage of the Taxes
(not to exceed one hundred percent (100%)) designated by the holder.


                                       24

<PAGE>


    IV.  EFFECTIVE DATE AND TERM OF THE PLAN

         A.   The Plan shall become effective immediately upon the Plan
Effective Date. However, the Salary Investment Option Grant and Director Fee
Option Grant Programs shall not be implemented until such time as the Primary
Committee or the Board may deem appropriate. Options may be granted under the
Discretionary Option Grant Program at any time on or after the Plan Effective
Date. However, no options granted under the Plan may be exercised, and no shares
shall be issued under the Plan, until the Plan is approved by the Corporation's
stockholders. If such stockholder approval is not obtained within twelve (12)
months after the Plan Effective Date, then all options previously granted under
this Plan shall terminate and cease to be outstanding, and no further options
shall be granted and no shares shall be issued under the Plan.

         B.   The Plan shall serve as the successor to the Predecessor Plan, and
no further options or direct stock issuances shall be made under the Predecessor
Plan after the Section 12 Registration Date. All options outstanding under the
Predecessor Plan on the Section 12 Registration Date shall be incorporated into
the Plan at that time and shall be treated as outstanding options under the
Plan. However, each outstanding option so incorporated shall continue to be
governed solely by the terms of the documents evidencing such option, and no
provision of the Plan shall be deemed to affect or otherwise modify the rights
or obligations of the holders of such incorporated options with respect to their
acquisition of shares of Common Stock.

         C.   One or more provisions of the Plan, including (without limitation)
the option/vesting acceleration provisions of Article Two relating to Changes in
Control, may, in the Plan Administrator's discretion, be extended to one or more
options incorporated from the Predecessor Plan which do not otherwise contain
such provisions.

         D.   The Plan shall terminate upon the EARLIEST of (i) March 21, 2010,
(ii) the date on which all shares available for issuance under the Plan shall
have been issued as fully-vested shares or (iii) the termination of all
outstanding options in connection with a Change in Control. Upon such plan
termination, all outstanding options and unvested stock issuances shall
thereafter continue to have force and effect in accordance with the provisions
of the documents evidencing such grants or issuances.

    V.   AMENDMENT OF THE PLAN

         A.   The Board shall have complete and exclusive power and authority to

amend or modify the Plan in any or all respects. However, no such amendment or
modification shall adversely affect the rights and obligations with respect to
stock options or unvested stock issuances at the time outstanding under the Plan
unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
pursuant to applicable laws or regulations.

         B.   Options to purchase shares of Common Stock may be granted under
the Discretionary Option Grant and Salary Investment Option Grant Programs and
shares of Common Stock may be issued under the Stock Issuance Program that are
in each instance in


                                       25

<PAGE>


excess of the number of shares then available for issuance under the Plan,
provided any excess shares actually issued under those programs shall be held in
escrow until there is obtained stockholder approval of an amendment sufficiently
increasing the number of shares of Common Stock available for issuance under the
Plan. If such stockholder approval is not obtained within twelve (12) months
after the date the first such excess issuances are made, then (i) any
unexercised options granted on the basis of such excess shares shall terminate
and cease to be outstanding and (ii) the Corporation shall promptly refund to
the Optionees and the Participants the exercise or purchase price paid for any
excess shares issued under the Plan and held in escrow, together with interest
(at the applicable Short Term Federal Rate) for the period the shares were held
in escrow, and such shares shall thereupon be automatically cancelled and cease
to be outstanding.

    VI.  USE OF PROCEEDS

         Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

    VII. REGULATORY APPROVALS

         A.   The implementation of the Plan, the granting of any stock option
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any granted option or (ii) under the Stock Issuance Program shall be
subject to the Corporation's procurement of all approvals and permits required
by regulatory authorities having jurisdiction over the Plan, the stock options
granted under it and the shares of Common Stock issued pursuant to it.

                          EMPLOYEE STOCK PURCHASE PLAN

         I.       PURPOSE OF THE PLAN

                  This Employee Stock Purchase Plan is intended to promote the
interests of LivePerson, Inc., a Delaware corporation, by providing eligible
employees with the opportunity to acquire a proprietary interest in the

such terms in the attached Appendix.

                  All share numbers reflect the 3-for-2 stock split of the
Common Stock which was effected on March 8, 2000.

         II.      ADMINISTRATION OF THE PLAN

         III.     STOCK SUBJECT TO PLAN

                  A.       The stock purchasable under the Plan shall be shares

year 2001, by an amount equal to one-half percent (0.5%) of the total number of
shares of Common Stock outstanding on the last trading day in December of the
immediately preceding calendar year, but in no event shall any such annual
increase exceed One Hundred Fifty Thousand (150,000) shares.

                  C.       Should any change be made to the Common Stock by
reason of any stock split, stock dividend, recapitalization, combination of

under each outstanding purchase right in order to prevent the dilution or

         IV.      OFFERING PERIODS

                  A.       Shares of Common Stock shall be offered for purchase
under the Plan through a series of successive offering periods until such time
as (i) the maximum number of shares of Common Stock available for issuance under
the Plan shall have been purchased or (ii) the Plan shall have been sooner
terminated.

                  B.       Each offering period shall be of such duration (not
to exceed twenty-four (24) months) as determined by the Plan Administrator prior
to the start date of such offering period. However, the initial offering period
shall commence at the Effective Time and terminate on the last business day in
April 2002. Subsequent offering periods shall commence as designated by the Plan
Administrator.

                  C.       Each offering period shall be comprised of a series
of one or more successive Purchase Intervals. Purchase Intervals shall run from
the first business day in May each year to the last business day in October of
the same year and from the first business day in November each year to the last
business day in April of the following year. However, the first Purchase
Interval in effect under the initial offering period shall commence at the
Effective Time and terminate on the last business day in October 2000.

                  D.       Should the Fair Market Value per share of Common
Stock on any Purchase Date within an offering period be less than the Fair
Market Value per share of Common Stock on the start date of that offering
period, then that offering period shall automatically terminate immediately
after the purchase of shares of Common Stock on such Purchase Date, and a new
offering period shall commence on the next business day following such Purchase
Date. The new offering period shall have a duration of twenty (24) months,
unless a shorter duration is established by the Plan Administrator within five
(5) business days following the start date of that offering period.

         V.       ELIGIBILITY

                  A.       Each individual who is an Eligible Employee on the
start date of an offering period under the Plan may enter that offering period
on such start date or on any subsequent Semi-Annual Entry Date within that
offering period, provided he or she remains an Eligible Employee.

                  B.       Each individual who first becomes an Eligible
Employee after the start date of an offering period may enter that offering
period on any subsequent Semi-Annual Entry Date within that offering period on
which he or she is an Eligible Employee.

                  C.       The date an individual enters an offering period
shall be designated his or her Entry Date for purposes of that offering period.

                  D.       To participate in the Plan for a particular offering
period, the Eligible Employee must complete the enrollment forms prescribed by
the Plan Administrator (including a

                                       2

<PAGE>

stock purchase agreement and a payroll deduction authorization) and file such
forms with the Plan Administrator (or its designate) on or before his or her
scheduled Entry Date.

         VI.      PAYROLL DEDUCTIONS

                  A.       The payroll deduction authorized by the Participant
for purposes of acquiring shares of Common Stock during an offering period may
be any multiple of one percent (1%) of the Cash Earnings paid to the Participant
during each Purchase Interval within that offering period, up to a maximum of
fifteen percent (15%). The deduction rate so authorized shall continue in effect
throughout the offering period, except to the extent such rate is changed in
accordance with the following guidelines:

                           (i)      The Participant may, at any time during the
         offering period, reduce his or her rate of payroll deduction to become
         effective as soon as possible after filing the appropriate form with
         the Plan Administrator. The Participant may not, however, effect more
         than one (1) such reduction per Purchase Interval.

                           (ii)     The Participant may, prior to the
         commencement of any new Purchase Interval within the offering period,
         increase the rate of his or her payroll deduction by filing the
         appropriate form with the Plan Administrator. The new rate (which may
         not exceed the fifteen percent (15%) maximum) shall become effective on
         the start date of the first Purchase Interval following the filing of
         such form.

                  B.       Payroll deductions shall begin on the first pay day
administratively feasible following the Participant's Entry Date into the
offering period and shall (unless sooner terminated by the Participant) continue
through the pay day ending with or immediately prior to the last day of that
offering period. The amounts so collected shall be credited to the Participant's
book account under the Plan, but no interest shall be paid on the balance from
time to time outstanding in such account. The amounts collected from the
Participant shall not be required to be held in any segregated account or trust
fund and may be commingled with the general assets of the Corporation and used
for general corporate purposes.

                  C.       Payroll deductions shall automatically cease upon the
termination of the Participant's purchase right in accordance with the
provisions of the Plan.

                  D.       The Participant's acquisition of Common Stock under
the Plan on any Purchase Date shall neither limit nor require the Participant's
acquisition of Common Stock on any subsequent Purchase Date, whether within the
same or a different offering period.

         VII.     PURCHASE RIGHTS

                  A.       GRANT OF PURCHASE RIGHT. A Participant shall be
granted a separate purchase right for each offering period in which he or she
participates. The purchase right shall be granted on the Participant's Entry
Date into the offering period and shall provide the Participant with the right
to purchase shares of Common Stock, in a series of successive installments over
the remainder of such offering period, upon the terms set forth below. The

                                       3

<PAGE>

Participant shall execute a stock purchase agreement embodying such terms and
such other provisions (not inconsistent with the Plan) as the Plan Administrator
may deem advisable.

                  Under no circumstances shall purchase rights be granted under
the Plan to any Eligible Employee if such individual would, immediately after
the grant, own (within the meaning of Code Section 424(d)) or hold outstanding
options or other rights to purchase, stock possessing five percent (5%) or more
of the total combined voting power or value of all classes of stock of the
Corporation or any Corporate Affiliate.

                  B.       EXERCISE OF THE PURCHASE RIGHT. Each purchase right
shall be automatically exercised in installments on each successive Purchase
Date within the offering period, and shares of Common Stock shall accordingly be
purchased on behalf of each Participant (other than Participants whose payroll
deductions have previously been refunded pursuant to the Termination of Purchase
Right provisions below) on each such Purchase Date. The purchase shall be
effected by applying the Participant's payroll deductions for the Purchase
Interval ending on such Purchase Date to the purchase of whole shares of Common
Stock at the purchase price in effect for the Participant for that Purchase
Date.

                  C.       PURCHASE PRICE. The purchase price per share at which
Common Stock will be purchased on the Participant's behalf on each Purchase Date
within the offering period shall be equal to eighty-five percent (85%) of the
lower of (i) the Fair Market Value per share of Common Stock on the
Participant's Entry Date into that offering period or (ii) the Fair Market Value
per share of Common Stock on that Purchase Date.

                  D.       NUMBER OF PURCHASABLE SHARES. The number of shares of
Common Stock purchasable by a Participant on each Purchase Date during the
offering period shall be the number of whole shares obtained by dividing the
amount collected from the Participant through payroll deductions during the
Purchase Interval ending with that Purchase Date by the purchase price in effect
for the Participant for that Purchase Date. However, the maximum number of
shares of Common Stock purchasable per Participant on any one Purchase Date
shall not exceed One Thousand (1,000) shares, subject to periodic adjustments in
the event of certain changes in the Corporation's capitalization. In addition,
the maximum number of shares of Common Stock purchasable in the aggregate by all
Participants on any one Purchase Date shall not exceed One Hundred Twelve
Thousand Five Hundred (112,500) shares, subject to periodic adjustments in the
event of certain changes in the corporation's capitalization.

                  E.       EXCESS PAYROLL DEDUCTIONS. Any payroll deductions not
applied to the purchase of shares of Common Stock on any Purchase Date because
they are not sufficient to purchase a whole share of Common Stock shall be held
for the purchase of Common Stock on the next Purchase Date. However, any payroll
deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable on the Purchase Date
shall be promptly refunded.

                  F.       TERMINATION OF PURCHASE RIGHT. The following
provisions shall govern the termination of outstanding purchase rights:

                                       4

<PAGE>

                           (i)      A Participant may, at any time prior to the
         next scheduled Purchase Date in the offering period, terminate his or
         her outstanding purchase right by filing the appropriate form with the
         Plan Administrator (or its designate), and no further payroll
         deductions shall be collected from the Participant with respect to the
         terminated purchase right. Any payroll deductions collected during the
         Purchase Interval in which such termination occurs shall, at the
         Participant's election, be immediately refunded or held for the
         purchase of shares on the next Purchase Date. If no such election is
         made at the time such purchase right is terminated, then the payroll
         deductions collected with respect to the terminated right shall be
         refunded as soon as possible.

                           (ii)     The termination of such purchase right shall
         be irrevocable, and the Participant may not subsequently rejoin the
         offering period for which the terminated purchase right was granted. In
         order to resume participation in any subsequent offering period, such
         individual must re-enroll in the Plan (by making a timely filing of the
         prescribed enrollment forms) on or before his or her scheduled Entry
         Date into that offering period.

                  (iii)    Should the Participant cease to remain an Eligible
         Employee for any reason (including death, disability or change in
         status) while his or her purchase right remains outstanding, then that
         purchase right shall immediately terminate, and all of the
         Participant's payroll deductions for the Purchase Interval in which the
         purchase right so terminates shall be immediately refunded. However,
         should the Participant cease to remain in active service by reason of
         an approved unpaid leave of absence, then the Participant shall have
         the right, exercisable up until the last business day of the Purchase
         Interval in which such leave commences, to (a) withdraw all the payroll
         deductions collected to date on his or her behalf for that Purchase
         Interval or (b) have such funds held for the purchase of shares on his
         or her behalf on the next scheduled Purchase Date. In no event,
         however, shall any further payroll deductions be collected on the
         Participant's behalf during such leave. Upon the Participant's return
         to active service (i) within ninety (90) days following the
         commencement of such leave or, (ii) prior to the expiration of any
         longer period for which such Participant's right to reemployment with
         the Corporation is guaranteed by either statute or contract, his or her
         payroll deductions under the Plan shall automatically resume at the
         rate in effect at the time the leave began. However, should the
         Participant's leave of absence exceed ninety (90) days and his or her
         re-employment rights not be guaranteed by either statute or contract,
         then the Participant shall be treated as a new Employee for purposes of
         the Plan and must, in order to resume participation in the Plan,
         re-enroll in the Plan (by making a timely filing of the prescribed
         enrollment forms) on or before his or her scheduled Entry Date into the
         offering period.

                  G.       CHANGE IN CONTROL. Each outstanding purchase right
shall automatically be exercised, immediately prior to the effective date of any
Change in Control, by applying the payroll deductions of each Participant for
the Purchase Interval in which such Change in Control occurs to the purchase of
whole shares of Common Stock at a purchase price per share equal to

                                        5

<PAGE>

eighty-five percent (85%) of the LOWER of (i) the Fair Market Value per share of
Common Stock on the Participant's Entry Date into the offering period in which
such Change in Control occurs or (ii) the Fair Market Value per share of Common
Stock immediately prior to the effective date of such Change in Control.
However, the applicable limitation on the number of shares of Common Stock
purchasable by all Participants in the aggregate shall not apply to any such
purchase.

                  The Corporation shall use its best efforts to provide at least
ten (10)-days prior written notice of the occurrence of any Change in Control,
and Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Change in Control.

                  H.       PRORATION OF PURCHASE RIGHTS. Should the total number
of shares of Common Stock to be purchased pursuant to outstanding purchase
rights on any particular date exceed the number of shares then available for
issuance under the Plan, the Plan Administrator shall make a pro-rata allocation
of the available shares on a uniform and nondiscriminatory basis, and the
payroll deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

                  I.       ASSIGNABILITY. The purchase right shall be
exercisable only by the Participant and shall not be assignable or transferable
by the Participant.

                  J.       STOCKHOLDER RIGHTS. A Participant shall have no
stockholder rights with respect to the shares subject to his or her outstanding
purchase right until the shares are purchased on the Participant's behalf in
accordance with the provisions of the Plan and the Participant has become a
holder of record of the purchased shares.

         VIII.    ACCRUAL LIMITATIONS

                  A.       No Participant shall be entitled to accrue rights to
acquire Common Stock pursuant to any purchase right outstanding under this Plan
if and to the extent such accrual, when aggregated with (i) rights to purchase
Common Stock accrued under any other purchase right granted under this Plan and
(ii) similar rights accrued under other employee stock purchase plans (within
the meaning of Code Section 423) of the Corporation or any Corporate Affiliate,
would otherwise permit such Participant to purchase more than Fifty Thousand
Dollars ($50,000) worth of stock of the Corporation or any Corporate Affiliate
(determined on the basis of the Fair Market Value per share on the date or dates
such rights are granted) for each calendar year such rights are at any time
outstanding.

                  B.       For purposes of applying such accrual limitations to
the purchase rights granted under the Plan, the following provisions shall be in
effect:

                           (i)      The right to acquire Common Stock under each
         outstanding purchase right shall accrue in a series of installments on
         each successive Purchase Date during the offering period on which such
         right remains outstanding.

                           (ii)     No right to acquire Common Stock under any
         outstanding purchase right shall accrue to the extent the Participant
         has already accrued in the

                                       6

<PAGE>

         same calendar year the right to acquire Common Stock under one (1) or
         more other purchase rights at a rate equal to Twenty-Five Thousand
         Dollars ($25,000) worth of Common Stock (determined on the basis of the
         Fair Market Value per share on the date or dates of grant) for each
         calendar year such rights were at any time outstanding.

                  C.       If by reason of such accrual limitations, any
purchase right of a Participant does not accrue for a particular Purchase
Interval, then the payroll deductions which the Participant made during that
Purchase Interval with respect to such purchase right shall be promptly
refunded.

                  D.       In the event there is any conflict between the
provisions of this Article and one or more provisions of the Plan or any
instrument issued thereunder, the provisions of this Article shall be
controlling.

         IX.      EFFECTIVE DATE AND TERM OF THE PLAN

                  A.       The Plan was adopted by the Board on March 21, 2000
and shall become effective at the Effective Time, PROVIDED no purchase rights
granted under the Plan shall be exercised, and no shares of Common Stock shall
be issued hereunder, until (i) the Plan shall have been approved by the
stockholders of the Corporation and (ii) the Corporation shall have complied
with all applicable requirements of the 1933 Act (including the registration of
the shares of Common Stock issuable under the Plan on a Form S-8 registration
statement filed with the Securities and Exchange Commission), all applicable
listing requirements of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock is listed for trading and all other
applicable requirements established by law or regulation. In the event such
stockholder approval is not obtained, or such compliance is not effected, within
twelve (12) months after the date on which the Plan is adopted by the Board, the
Plan shall terminate and have no further force or effect, and all sums collected
from Participants during the initial offering period hereunder shall be
refunded.

                  B.       Unless sooner terminated by the Board, the Plan shall
terminate upon the EARLIEST of (i) March 21, 2010, (ii) the date on which all
shares available for issuance under the Plan shall have been sold pursuant to
purchase rights exercised under the Plan or (iii) the date on which all purchase
rights are exercised in connection with a Corporate Transaction. No further
purchase rights shall be granted or exercised, and no further payroll deductions
shall be collected, under the Plan following such termination.

         X.       AMENDMENT/TERMINATION OF THE PLAN

                  A.       The Board may alter, amend, suspend or terminate the
Plan at any time to become effective immediately following the close of any
Purchase Interval. However, the Plan may be amended or terminated immediately
upon Board action, if and to the extent necessary to assure that the Corporation
will not recognize, for financial reporting purposes, any compensation expense
in connection with the shares of Common Stock offered for purchase under the
Plan, should the financial accounting rules applicable to the Plan at the
Effective Time

                                       7

<PAGE>

be subsequently revised so as to require the recognition of compensation expense
in the absence of such amendment or termination.

                  B.       In no event may the Board effect any of the following
amendments or revisions to the Plan without the approval of the Corporation's
stockholders: (i) increase the number of shares of Common Stock issuable under
the Plan, except for permissible adjustments in the event of certain changes in
the Corporation's capitalization, (ii) alter the purchase price formula so as to
reduce the purchase price payable for the shares of Common Stock purchasable
under the Plan or (iii) modify eligibility requirements for participation in the
Plan.

         XI.      GENERAL PROVISIONS

                  A.       Nothing in the Plan shall confer upon the Participant
any right to continue in the employ of the Corporation or any Corporate
Affiliate for any period of specific duration or interfere with or otherwise
restrict in any way the rights of the Corporation (or any Corporate Affiliate
employing such person) or of the Participant, which rights are hereby expressly
reserved by each, to terminate such person's employment at any time for any
reason, with or without cause.

         B.       All costs and expenses incurred in the administration of the
Plan shall be paid by the Corporation; however, each Plan Participant shall bear
all costs and expenses incurred by such individual in the sale or other
disposition of any shares purchased under the Plan.

         C.       The provisions of the Plan shall be governed by the laws of
the State of New York without regard to that State's conflict-of-laws rules.

         selling price per share of Common Stock on the date in question on the
         Stock Exchange determined by the Plan Administrator to be the primary
         market for the Common Stock, as such price is officially quoted in the
         composite tape of transactions on such exchange. If there is no closing
         selling price for the Common Stock on the date in question, then the
