   This summary highlights information contained in other parts of this
prospectus. It is not complete and may not contain all of the information that

including the financial statements and related notes. Unless otherwise
indicated, all information in this prospectus:

  . assumes a    - for-1 split of our currently outstanding common stock
    immediately before the closing of this offering;

  . reflects the conversion of all of our outstanding preferred stock and

    closing of this offering; and

  . assumes that the underwriters will not exercise their over-allotment
    option.

                                   LinkShare

Our Company

   LinkShare creates and operates networks that enable businesses to form and
manage online partnerships with thousands of independent Web sites for a
variety of purposes. By combining the reach of our fast-growing networks with
the capabilities of our patented LinkShare Synergy(R) technology, we enable
online businesses to:

  . find the right Web sites for their business relationships;

  . negotiate the terms of their relationships with the publishers of those
    Web sites; and

  . evaluate the success of those relationships.

   Our first network, The LinkShare NetworkTM, enables online merchants to
establish performance-based relationships with thousands of Web site publishers
who seek to convert visitor traffic into revenues by becoming marketing
"affiliates" of those merchants. By providing a quick and easy way to establish
hyperlink promotions for merchant members of our network, we enable an
affiliate Web site publisher to drive traffic from its site to the merchants'
Web sites. If a visitor accesses a merchant's Web site through that hyperlink
and takes a prescribed action, such as buying a product, the affiliate earns a
fee payable by that merchant. We view The LinkShare NetworkTM as a model for
additional networks and applications that we may develop as e-commerce grows.

   The LinkShare NetworkTM has facilitated more than three million marketing
relationships among thousands of participating affiliates and more than 450
merchants, including leading companies like Dell, Toysrus.com, OfficeMax.com,
L.L. Bean and CVS.com. In January 2000, we announced the creation of B2B
LinkShareTM, a separate affiliate network designed to serve the growing
business-to-business e-commerce market that we expect to launch by the end of
March 2000.

Our Sources of Revenue

   We receive substantially all of our revenues from fees that we collect from
the merchant members of The LinkShare NetworkTM. Our merchant members pay us
two types of fees:

  . licensing fees for the use of our software and access to our network; and

  . network fees, which are based on:

    . the volume and dollar amount of sales and other activities generated
      through their hyperlinks with marketing affiliates, and

    . charges for optional packages of enhanced software features, support
      services and back-office services.

                                       1
<PAGE>


Our revenue generating potential increases exponentially with the addition of
each new member to one or more of our networks since each of our members has
the ability to create thousands of online business relationships.

Our Market Opportunity

   According to International Data Corporation, total e-commerce is expected to
grow to over $1.6 trillion by 2003. This growth represents both an opportunity
and a challenge for online merchants and advertisers seeking a cost-effective
method of reaching target audiences dispersed over millions of Web sites. These
businesses are expected to increasingly concentrate their online marketing
efforts on those Web sites that are best able to reach their target audiences
and charge only for results. Forrester Research, Inc. predicts that, by 2003,
performance-based marketing will account for 50% of the estimated $17.2 billion
of projected annual U.S. online advertising expenditures. The LinkShare
NetworkTM provides an efficient, performance-based marketing solution that
enables businesses to make better marketing decisions, reduce their customer
acquisition costs and generate greater revenue.

Our Strategy

   Our goal is to be the premier provider of open networks that facilitate
online commercial activity. Key elements of our growth strategy include:

  . continuing to add quality merchants and affiliates to our existing
    networks;

  . introducing new affiliate networks tailored to meet the needs of
    identifiable business communities;

  . adapting our technology and network model to serve the needs of emerging
    online commercial activity;

  . continuing to expand and enhance the features and performance of our
    software and revenue-generating service offerings; and

  . introducing our network solutions into suitable international markets.

                                  RISK FACTORS

   An investment in the shares of our common stock offered by this prospectus
involves a high degree of risk. This section describes some, but not all, of
the risks associated with our business. You should carefully review the
following risk factors as well as the other information set forth in this
prospectus before making an investment.

                         Risks Relating to Our Business

Our limited operating history makes it difficult to evaluate our business and
prospects.

   We launched The LinkShare NetworkTM, our initial and currently most
significant service offering, in 1997. With such a limited operating history,
our past results do not provide meaningful bases for evaluating an investment
in our common stock, and you should not rely on them as indicators of our
future performance. You should consider all the risks and difficulties we may
encounter as an early stage company in our industry, including:

  . our ability to establish and maintain sustainable online affiliate
    networks that generate large and growing volumes of revenue producing
    transactions;

  . our ability to gain widespread acceptance of our network solutions by
    online businesses; and

  . the new and evolving nature of e-commerce in general.

We have incurred substantial losses and anticipate continued losses.

   Since our inception, we have incurred substantial losses. Our losses were
$193,428 for the fiscal year ended June 30, 1998, $3.4 million for the fiscal
year ended June 30, 1999, and $3.2 million for the six months ended December
31, 1999. At December 31, 1999, we had an accumulated deficit of $6.8 million.

   We anticipate that expenditures to develop, market and support our products
and services will increase substantially in the future. In particular, we
expect to spend significantly on the following activities:

  . expanding and enhancing our networks and the capabilities of our software
    systems;

  . expanding and improving our sales and marketing operations;

  . broadening our customer support capabilities;

  . hiring additional management, technical and marketing personnel; and

  . introducing new networks in international markets and in additional
    online business communities.

   For the foreseeable future, we expect to experience additional losses. These
additional losses will increase our accumulated deficit.

Our future operating results are uncertain and are likely to fluctuate
significantly.

   We expect that our revenues, gross margins and other operating results will
fluctuate significantly from quarter to quarter, due to many factors,
including:

  . the rate at which new merchants and marketing affiliates join our
    networks;

  . variations in transaction volume generated by new and existing members of
    our networks;

  . the volume of our sales of existing or planned products and services,
    including future versions of software and additional services we may
    provide to members of our networks;

  . the rate at which we introduce our networks in international markets and
    in additional online business communities;

                                       5
<PAGE>

  . the growth or possible decline of online commerce;

  . the mix of revenues from our different sources, such as network fees and
    licensing fees;

  . changes in our, or our competitors', prices or pricing models; and

  . the extent to which our network members renew their software licenses and
    upgrade their support contracts.

   Although we have experienced revenue growth in recent periods, this growth
may not be sustainable. As a result, we do not believe that our historical
results of operations are necessarily indicative of future performance. If our
results of operations in any period are below the expectations of securities
analysts and investors, the trading price of our stock will likely decrease
materially.

Our success depends on market acceptance of online performance-based marketing.

   We expect that nearly all of our future revenues will be derived from fees
generated by the transactions and other activities taking place over our
networks, from sales of services that support those networks and from licensing
fees. Our future financial performance depends on the acceptance and growth of
our networks and the successful development, introduction and customer
acceptance of new and enhanced products and services to support these networks.
Failure of the market for online performance-based marketing to develop as we
expect, or lack of customer acceptance of our networks, will have a material
and adverse effect on our business, results of operations and financial
condition.

We face intense competition from many companies, some of which have
significantly greater resources than we do.

   The market for online performance-based marketing is new, intensely
competitive and rapidly evolving. We expect competition from existing
competitors and new market entrants to continue to increase. We believe that
our ability to compete depends on many factors both within and beyond our
control, including the timing and market acceptance of our, and our
competitors', products and services.

   We compete against companies of all sizes with respect to the products and
services we provide, and we expect to face increased competition from some of
these companies as they broaden the scope of their products and services.

   We compete with software/service providers, such as Be Free, Inc., that
offer merchants software and services to operate their own private label
affiliate marketing programs. These programs can serve as an alternative to the
affiliate marketing programs conducted over our open networks. Private label
providers, such as Be Free, aggressively market their programs to many of the
online merchants that we may target. Be Free has substantially more financial
resources than we do and a larger sales force.

   We also compete against other public network providers, such as Microsoft's
LinkExchange and Commission Junction. To some extent, we may also compete
against enterprise software providers, ad server companies and companies that
have internally developed their own affiliate marketing solutions.

Our planned international expansion may be expensive and may not succeed.

   We intend to expand our operations internationally in future periods by
developing networks of online businesses located in foreign countries and by
opening international offices and hiring sales, marketing and support personnel
in those countries. We have little experience in marketing, selling and
supporting our services in foreign countries. As a result, our international
expansion may be more difficult or take longer than we anticipate, especially
due to language barriers and the less advanced Internet infrastructure that
exists in some of these countries. We will need to devote significant
management and financial resources to our international efforts.


                                       6
<PAGE>

   International operations are subject to a variety of additional risks that
could seriously harm our financial condition and operating results, including:

  . currency exchange risks;

  . difficulties in complying with laws and regulations of different
    countries;

  . potentially adverse tax consequences;

  . tariffs and general export restrictions, including export controls
    relating to encryption technology;

  . difficulties in staffing and managing foreign operations;

  . political instability;

  . difficulties in enforcing contractual and intellectual property rights in
    some countries;

  . seasonal reductions in business activity during the summer months in
    Europe and certain other parts of the world; and

  . the impact of local economic conditions and practices.

We may need to raise additional financing, which may not be available when we
need it or on acceptable terms.

   We may need to raise more money following this offering. Our future capital
requirements will depend on many factors, including, but not limited to:

  . the rate at which we develop and introduce additional products and
    services;

  . the market acceptance and competitive position of our products and
    services;

  . the level of promotion and advertising required to market our products
    and services and attain a competitive position in the marketplace; and

  . the response of competitors to our products and services.

   If we require additional funds, these funds might not be available in
sufficient amounts or on terms favorable to us or our stockholders. If we raise
additional funds through the issuance of common stock, we may issue shares at a
price lower than the market price of our common stock at the time of the sale,
which may adversely affect the market for our common stock.

                          Risks Relating to Management

Managing our rapid growth may be difficult.

   We are growing rapidly as we develop The LinkShare NetworkTM and our other
affiliate networks, increase our product offerings and expand into new markets.
Our rapid growth has placed, and will continue to place, a significant strain
on our management. Our personnel, systems, procedures and controls may be
inadequate to support our future operations. We will need to hire, train and
retain additional management and support personnel. We will also need to
implement improved billing and collection procedures and financial and
management information systems. If we do not adequately address these needs or
otherwise effectively manage our growth, it will have a material and adverse
affect on our business, operating results and financial condition.

We depend on the continued services of our founders and other key personnel,
whose knowledge of our business and technical expertise would be difficult to
replace.

   Our products and services are complex, and we are substantially dependent
upon the continued services of our senior executives, especially our Chief
Executive Officer, Stephen Messer, our President, Heidi Messer, and

                                       7
<PAGE>

our key marketing and technical personnel. The loss of any, or a group of,
these individuals, particularly to a competitor, could materially and adversely
affect our business, financial condition and operating results.

We must attract and retain a growing number of skilled employees to develop our
business.

   Our business depends on having highly trained account executives and
software developers. We will need to continue hiring additional personnel as
our business grows. Competition for personnel, particularly for employees with
technical expertise, is intense and the costs of hiring and retaining such
personnel are high. Our business, financial condition and operating results
will be materially and adversely affected if we cannot hire and retain a
sufficient number of suitable personnel.

Our management team is new and, if they are unable to work together
effectively, our business could be seriously harmed.

   Our business is highly dependent on the ability of our management team to
work together effectively to meet the demands of our growth. We grew from three
employees at June 30, 1998, to 97 employees at December 31, 1999. Of our
current management team, only seven members were employed by us at June 30,
1999. These individuals have not previously worked together as a management
team and have had only limited experience managing a rapidly growing company on
either a public or private basis. If they are unable to effectively integrate
themselves into our business or work together as a management team, we may not
be able to manage our business effectively.

                          Risks Relating to Technology

Our rapid growth will place increasing demands on our technology that we may
not be able to meet.

   As traffic over our networks continues to increase, we must expand and
upgrade our technology, transaction processing systems and network hardware and
software. We may not be able to accurately project the rate of growth of our
networks. In addition, we may not be able to expand and upgrade our systems and
network hardware and software capabilities at a sufficient pace to accommodate
increased use of our networks. If we do not appropriately upgrade our systems
and network hardware and software, our business, financial condition and
operating results will be materially and adversely affected.

Our success depends on our ability to develop new products and keep pace with
rapid technological change.

   Our products are designed to operate on a variety of hardware and software
platforms employed by our customers. We must continually modify and enhance our
products to keep pace with changes in hardware and software platforms and
database technology. As a result, uncertainties related to the timing and
nature of new product announcements, introductions or modifications by third
party vendors could materially and adversely affect our business, results of
operations and financial condition.

System failures and security breaches could cause us to lose clients and expose
us to liability.

   Online merchants and their marketing affiliates that participate in our
networks depend on us to accurately track, store and report the traffic and
sales that are attributable to the links they establish. Software defects,
system failures, natural disasters, human error and other factors could lead to
inaccurate or lost information or the inability to access our networks.
Although we have experienced almost no unplanned system outages in the past, we
may experience outages in the future. In addition, members of our networks
consider much of the transactional data that we collect and store to be highly
sensitive. Our systems could be vulnerable to computer

                                       8
<PAGE>

viruses and physical and electronic break-ins, and third parties may attempt to
breach our security. Our loss of information, our delivery of inaccurate
information or a breach or failure of our security mechanisms that leads to
unauthorized disclosure of information could lead to customer dissatisfaction,
damage to our reputation and possible claims against us for damages. If we are
not able to consistently deliver accurate information to our customers,
maintain the security of their confidential information and maintain the
availability of our networks, our business will be materially and adversely
affected.

Undetected defects in our technology could adversely affect our business.

   Technology as complex as ours may contain errors, defects or performance
problems, commonly called "bugs." Although we regularly test our technology, we
cannot assure you that our testing will detect every potential defect, error or
performance problem. The discovery of a serious software defect, error or
performance problem in our technology could result in:

  . the diversion of scarce resources away from customer service and product
    development;

  . lost revenues;

  . delays in customer acceptance of our products; and

  . damage to our reputation.

Any such result could have a material and adverse effect on our business. Our
customers and potential customers may be particularly sensitive to any post-
release defects, errors or performance problems because a failure of our
systems to accurately monitor an online relationship could result in lost or
reduced revenue to the affiliate members of our networks, or overpayment by
merchant members, during that failure.

We may not be able to protect our intellectual property rights, and we may
infringe the intellectual property rights of others.

   Intellectual property rights are important to our success and our
competitive position. Although we seek to protect our intellectual property
rights through patents, copyrights, trademark and service mark registration and
other means, our actions may be inadequate to protect our technology and our
intellectual property rights or to prevent others from claiming violations of
their patents, copyrights, trademarks and other intellectual property rights.
Patent, copyright and trademark protection may be unenforceable or limited in
certain countries. We cannot be certain that any of our intellectual property
rights would withstand challenge by a third party or will be of value in the
future. The validity, enforceability and scope of protection of certain
intellectual property rights in Internet-related industries is uncertain and
still evolving. To date, we have not been notified that our technologies
infringe the intellectual property rights of third parties, but there can be no
assurance that third parties will not claim infringement by us of any past,
current or future intellectual property rights. Any such claim, whether
meritorious or not, could be time-consuming to defend, result in costly
litigation, cause service upgrade delays or require us to enter into royalty or
licensing agreements.

The actions of the members of our affiliate networks may expose us to
liability.

   We facilitate the formation of partnerships between online businesses and
provide means for the delivery of advertisements, promotions and other
communications by and between those businesses. We are not party to the
contracts formed by these online partners, and we do not and cannot screen all
of the communications generated by them or the content of their Web sites.
However, because of our role in facilitating our members' online commerce
activities, we may be subject to claims based on their actions and face
potential liability for defamation, negligence, copyright, patent or trademark
infringement and other claims based on their contractual relations or the
materials generated by their promotions, displayed on their Web sites or
included in their e-mail messages. Consequently, we may be involved in legal
proceedings and disputes that we had no way of foreseeing or avoiding and that
are costly to resolve regardless of their merit.

                                       9
<PAGE>

We depend on a limited number of hardware and software vendors for essential
products.

   We buy and lease hardware, including our servers and storage arrays, from
Sun Microsystems Inc. and MTI Corporation. We also license software, including
operating systems, Web server technology, database technology, graphical user
interface technology and encryption technology, primarily from Sun Microsystems
and Oracle Corp. If these vendors change the terms of our lease or license
arrangements such that it becomes uneconomical for us to continue using their
hardware or software, or if they are unable or unwilling to supply us with the
hardware or software we need in the amount and at the time required, our
business may be materially and adversely affected until equivalent hardware or
software can be identified, procured and integrated into our existing systems.

                         Risks Relating to Our Industry

We will not achieve our growth plans unless Internet usage grows and Internet
performance is adequate.

   If electronic commerce does not grow or grows slower than we expect, our
business will be adversely affected. Our long-term success depends on
widespread market acceptance of electronic commerce, which is subject to a high
level of uncertainty. A number of factors could prevent this acceptance,
including the following:

  . Electronic commerce is at an early stage, and buyers may be unwilling to
    shift their purchasing from traditional vendors to online vendors.

  . The necessary network infrastructure for substantial growth in usage of
    the Internet may not be adequately developed.

  . Insufficient availability of or changes in telecommunication services
    could result in slower response times.

  . Adverse publicity and consumer concern about the security and privacy of
    online transactions could discourage the growth of e-commerce.

  . Companies may fail to meet their customers' expectations in delivering
    goods and services sold over the Internet.

Governmental regulations and legal uncertainties may adversely affect our
business.

   We are subject not only to regulations applicable to businesses generally,
but also laws and regulations directly applicable to electronic commerce.
Although there currently are few such laws and regulations, state, federal and
foreign governments may adopt a number of laws and regulations that may govern
or restrict any of the following issues:

  . user privacy;

  . the pricing and taxation of goods and services offered over the Internet;

  . the content of Web sites;

  . consumer protection; and

  . the characteristics and quality of products and services offered over the
    Internet.

Any such legislation or regulation could dampen the growth of the Internet and
decrease its acceptance as a commercial medium, in which event the need for our
products and services would be reduced seriously and our business, financial
condition and operating results would be materially and adversely affected.

                        Risks Relating to this Offering

Our management has broad discretion as to how to use the proceeds from this
offering.

   We intend to use the proceeds from this offering for general corporate
purposes, including working capital and capital expenditures. Our management
will have broad discretion over how we use these proceeds. You will not have
the opportunity to evaluate the economic, financial or other information on
which we base our decisions regarding how to use the proceeds from this
offering, and we may spend these proceeds in ways with which you may disagree.
Pending any of these uses, we plan to invest the proceeds of this offering in
short-term, investment-grade, interest-bearing securities. We cannot predict
whether these investments will yield a favorable return.

Our common stock has never been publicly traded, and you may not be able to
sell your shares at or above the initial offering price.

   There has not been a public market for our common stock prior to this
offering. We cannot predict the extent to which a trading market will develop
or how liquid that market might become. Further, the market price of our common
stock may decline below the initial public offering price. The initial public
offering price will be determined by negotiations between our management and
representatives of the underwriters and may not be indicative of the price at
which our common stock will trade in the public market.

Internet-related stock prices are especially volatile, and this volatility may
depress our stock price. We may be subject to lawsuits as a result of extreme
fluctuations in our stock price.

   Notwithstanding the general volatility of the stock market, the market price
of our common stock is likely to be highly volatile as the market for
technology and Internet-related companies, in particular, has been highly
volatile. Investors may not be able to resell their shares of our common stock
following periods of high volatility in the event that trading of our common
stock were to be suspended by the exchange on which it trades. The trading
prices of shares of many technology and Internet-related companies have reached
historical highs within the last 52 weeks. During the same period, prices for
the shares of these companies have been highly volatile, and many have recorded
lows well below their historical highs. We cannot assure you that our common
stock will trade at the same levels of other Internet stocks or that Internet
stocks in general will sustain their current market prices.

   Factors that could cause volatility in the market price of our common stock
may include, among other things:

  . actual or anticipated variations in quarterly operating results;

  . announcements of technological innovations;

  . new sales formats or new products or services;

  . changes in financial estimates by securities analysts;

  . conditions or trends in the Internet industry;

  . changes in the market valuations of other Internet companies;

  . announcements by us or our competitors of significant acquisitions,
    strategic partnerships or joint ventures;

  . capital commitments;

  . additions or departures of key personnel; and

  . sales of additional shares of our common stock.

   Many of these factors are beyond our control and may materially and
adversely affect the market price of our common stock, regardless of our
operating performance.

                                       11
<PAGE>

   Following a significant decline in the market price of a company's
securities, securities class action litigation has often been instituted. If
this were to happen to us, even if the claims had no merit, litigation would be
expensive and would divert management's attention from the operation of our
business.

We are controlled by a few major stockholders whose interests may be different
than yours.

   Following the closing of this offering, Stephen Messer and Heidi Messer will
beneficially own  % and  %, respectively, of our outstanding common stock, and
our officers and directors collectively will beneficially own  %. In addition,
Internet Capital Group, Inc. and Comcast Interactive Capital, LP will own  %
and  % respectively. As a result, these stockholders will be able to determine
the outcome of any matter requiring a stockholder vote and, as a result, our
management and affairs. Matters that typically require stockholder approval
include the following:

  . election of directors;

  . merger or consolidation with another company; and

  . sale of all or substantially all of our assets.

   Internet Capital Group has significant, in some cases controlling, interests
in a growing number of businesses engaged in e-commerce. Some of these
businesses may be or may in the future become competitors or strategic partners
of LinkShare, and conflicts of interest may arise as a result of Internet
Capital Group's investment in these or other businesses. An affiliate of
Comcast is also a major stockholder of Internet Capital Group. Comcast and its
affiliates also hold ownership interests in other businesses that are or may
become competitors or strategic partners of LinkShare, which could lead to
conflicts of interest. The investment objectives of Internet Capital Group and
Comcast may differ from those of other stockholders, including our future
public stockholders. The concentration of ownership of LinkShare stock may also
delay, deter or prevent a change of control, which could reduce the market
price of our common stock.

You will experience an immediate and substantial dilution in the book value of
your investment.

   The initial public offering price of our common stock is substantially
higher than what the net tangible book value per share of the common stock will
be immediately after this offering. If you purchase our common stock in this
offering, you will incur immediate dilution of approximately $    in the net
tangible book value per share of our common stock from the price you pay for
our common stock, based upon an assumed initial public offering price of $
per share. The exercise of outstanding options may result in further dilution.

The substantial number of shares that will be eligible for sale in the near
future may cause the market price of our common stock to decline.

   A substantial number of shares of common stock will be available for sale in
the public market following this offering, which could adversely affect the
market price for our common stock. See "Shares Eligible for Future Sale" for a
more detailed description of the eligibility of shares of our common stock for
future sale.

We have various mechanisms in place to discourage takeovers.

   Certain provisions of our restated certificate of incorporation and bylaws
may discourage, delay or prevent a change in control of LinkShare that a
stockholder may consider favorable. These provisions include the following:

  . authorizing the issuance of "blank check" preferred stock that could be
    issued by our board of directors to increase the number of outstanding
    shares and thwart a takeover attempt;

  . classifying our board of directors with staggered three-year terms, which
    may lengthen the time required to gain control of our board of directors;

                                       12
<PAGE>

  . limiting who may call special meetings of stockholders;

  . prohibiting stockholder action by written consent, thereby requiring all
    stockholder actions to be taken at a meeting of the stockholders; and

  . establishing advance notice requirements for nominations of candidates
    for election to the board of directors or for proposing matters that can
    be acted upon by stockholders at stockholder meetings.

   In addition, Section 203 of the Delaware General Corporation Law and our
stock option plan may discourage, delay or prevent a change in control of
LinkShare.

                 CAUTIONARY NOTE ON FORWARD-LOOKING STATEMENTS

   This prospectus contains forward-looking statements, which involve risks and
uncertainties. These forward-looking statements are not historical facts but
rather are based on current expectations, estimates and projections about our
industry, our beliefs and assumptions. We use words such as "anticipates,"
"expects," "intends," "plans," "believes," "seeks," "estimates" and variations
of these words and similar expressions to identify forward-looking statements.
These statements are not guarantees of future performance and are subject to
certain risks, uncertainties and other factors, some of which are beyond our
control, are difficult to predict and could cause actual results to differ
materially from those expressed or forecasted in the forward-looking
statements. These risks and uncertainties include those described in "Risk
Factors" and other parts of this prospectus. You should not place undue
reliance on these forward-looking statements, which reflect our management's
view only as of the date of this prospectus.

                                USE OF PROCEEDS

   Our net proceeds from the sale of the    shares of common stock in this
offering will be approximately $    million, or approximately $    million if
the underwriters' over-allotment option is exercised in full, at an assumed
public offering price of $    per share and after deducting the underwriting
discounts and commissions and our estimated offering expenses.

   The primary purposes of this offering are to obtain additional working
capital, to create a public market for our common stock and to facilitate
future access to public equity markets. Although we expect to use the proceeds
for working capital, capital expenditures and other general corporate purposes,
at the date of this prospectus, we have not allocated the net proceeds of this
offering for specific uses. The actual amounts expended for these purposes will
vary significantly depending on a number of factors, including revenue growth,
if any, and the timing of any expansion of our business.

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

                                DIVIDEND POLICY

   We have never paid cash dividends on our capital stock. We expect to retain
our future earnings, if any, to operate and expand our business, and we do not
anticipate paying any cash dividends in the foreseeable future. As a result,
our stockholders will need to sell their shares to realize any return on their
investment.

                                 CAPITALIZATION

   The following table sets forth our capitalization as of December 31, 1999,
on:

  . an actual basis,

  . a pro forma basis that reflects:

    . a    -for -1 split of our currently outstanding common stock
      immediately before the closing of this offering; and

    . the automatic conversion of all outstanding shares of preferred stock
      into 3,242,148 shares of common stock upon the closing of this
      offering;

    . the issuance of convertible notes payable and advances from
      stockholders from January 1, 2000, through February 7, 2000, for net
      proceeds of $3,655,000; and

    . the automatic conversion of all outstanding notes into      shares of
      common stock upon the closing of this offering; and

  . a pro forma as adjusted basis that reflects our issuance and sale of
    shares of common stock in this offering at the initial public offering
    price of $    per share and our receipt and application of the estimated
    net proceeds from this offering, after deducting the underwriting
    discounts and commissions and our estimated offering expenses.

   Shares of common stock reflected by this table or in the calculation of
stockholders' equity do not include:

  . 1,195,670 shares issuable upon exercise of outstanding options at
    December 31, 1999, at a weighted average exercise price of $5.69 per
    share;

  . 1,380,927 shares issuable at December 31, 1999, upon exercise of options
    that may be granted under our stock option plan;

  . 41,970 shares of common stock issuable upon the exercise of all of our
    outstanding warrants; and

  .     shares subject to the underwriters' over-allotment option.

   We expect     shares of common stock to be outstanding immediately after the
closing of this offering.

                                    DILUTION

   If you invest in our common stock, your interest will be diluted to the
extent of the difference between the public offering price per share of our
common stock and the pro forma as adjusted net tangible book value per share of
our common stock. At December 31, 1999, the net tangible book value of our
common stock was $4.6 million or $     per share of common stock, on a pro
forma basis after giving effect to:

  . the automatic conversion of all outstanding shares of preferred stock
    into 3,242,148 shares of common stock upon the closing of this offering;

  . the issuance of convertible notes payable and advances from stockholders
    from January 1, 2000, through February 7, 2000, for net proceeds of
    $3,655,000; and

  . the automatic conversion of all outstanding notes into      shares of
    common stock upon the closing of this offering.

   "Net tangible book value" per share represents the amount of our total
tangible assets reduced by the amount of our total liabilities, divided by the
number of shares of common stock outstanding. At December 31, 1999, the net
tangible book value of our common stock, on a pro forma basis as adjusted for
the sale of     shares offered in this offering and the application of the
estimated net proceeds from that sale of $    million, would have been
approximately $    per share. This value is based on an assumed initial public
offering price of $    per share and the deduction of underwriting discounts
and commissions and our other estimated offering expenses. The difference
between the pro forma and pro forma as adjusted net tangible book value of our
common stock represents an immediate increase of $    per share to our existing
stockholders and an immediate dilution of $    per share to new investors who
purchase shares in this offering. The following table illustrates this per
share dilution:

   You should read the selected financial data set forth below in conjunction
with "Management's Discussion and Analysis of Financial Condition and Results
of Operations" and our financial statements and the related notes included
elsewhere in this prospectus. The statements of operations data for the fiscal
years ended June 30, 1998 and 1999 and the balance sheet data as of June 30,
1998 and 1999 are derived from our audited financial statements. The statements
of operations data for the six-month periods ended December 31, 1998 and 1999
and the balance sheet data as of December 31, 1999 are derived from our
unaudited financial statements. Our unaudited financial statements have been
prepared on the same basis as our audited financial statements and, in our
opinion, include all adjustments, consisting only of normal recurring
adjustments that we consider necessary for a fair presentation of our results
of operations and financial condition for the periods and at the date
presented. Historical results are not necessarily indicative of results that
may be expected for any future period.

                    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 financial statements and the
related notes included in another part of this prospectus. This discussion
contains forward-looking statements that involve risks and uncertainties. Our
actual results may differ materially from those anticipated in these forward-
looking statements as a result of certain factors, including, but not limited
to, those set forth in the sections of this prospectus titled "Risk Factors"
and "Our Business."

Overview

   LinkShare enables the formation of performance-based online business
relationships. Participants in our networks can find the right Web sites with
which to partner, negotiate the terms of their partnerships and evaluate their
success. Our first and largest network, The LinkShare Network(TM), enables
online merchants to establish relationships with thousands of Web site
publishers who seek to convert visitor traffic into revenues by linking their
Web sites with the Web sites of those merchants. If a visitor accesses a
merchant's Web site through that link and takes a prescribed action, such as
buying a product, the affiliate earns a fee payable by that merchant.

   We were incorporated on July 1, 1997, and launched The LinkShare Network(TM)
later that year. To date, nearly all of our revenues have been derived from the
operation of The LinkShare Network(TM). In October 1999, we introduced
TrafficShareTM as an additional feature available to members of The LinkShare
Network(TM) whose primary goal is increasing traffic to their Web sites rather
than generating sales. In January 2000, we announced the creation of B2B
LinkShareTM, a separate affiliate network designed to serve the growing online
business-to-business market that we expect to launch by the end of March 2000.

   Our fiscal year ends on June 30 of each year. All references to fiscal years
1998 and 1999 in the discussion that follows refer to the fiscal years ended
June 30, 1998, and June 30, 1999, respectively.

Sources of Revenue

   To date, substantially all of our revenues have been derived from two types
of fees that we collect from the merchant members of The LinkShare Network(TM):

  . licensing fees for the use of our software and access to the network; and

  . network fees, which are based on:

    . the volume and dollar amount of sales and other activities generated
      through our merchant members' links with their affiliates, and

    . charges for optional packages of enhanced software features, support
      services and back-office services.

   Access to The LinkShare Network(TM) is free to affiliates, and we currently
do not charge any fees for the services we provide to the affiliate members of
that network.

   Merchants pay us an initial license fee upon first signing a contract for
the use of our LinkShare Synergy(R) software and access to The LinkShare
Network(TM). Merchants subsequently pay a lower renewal fee each year during
the term of their respective contracts. Our contracts with merchants generally
have terms of up to three years and renew automatically for successive terms of
up to two years, unless either party gives notice not to extend. We typically
bill each merchant once a month for fees based on the transactions or other
activities generated by that merchant's links with its affiliates. We also
provide optional support services, such as enhanced software packages, and
back-office services, such as e-mail generation and distribution and check
disbursement, for which merchants pay us additional fees. To date, these
additional fees have represented a minimal portion of our revenue.

                                       18
<PAGE>

   We defer revenue from licensing fees at the time of software shipment and
billing and recognize revenue ratably over the related contractual period
during which we provide the applicable merchant with access to our networks. We
recognize revenue from network fees during the period in which they are earned
or during the period in which the applicable service is provided.

   We have incurred significant net losses since the commencement of
operations. Net losses totaled $193,428 for fiscal year 1998, $3.4 million for
fiscal year 1999 and $3.2 million for the six months ended December 31, 1999.
At December 31, 1999, we had an accumulated deficit of $6.8 million. We
anticipate that we will spend significantly on developing, marketing and
supporting our products and services in the future. As a result, we expect to
experience additional losses that will increase our accumulated deficit.

Comparison of Results of Operation for the Six-Month Periods Ended December 31,
1998 and 1999

 Revenues

   Revenues increased by $2.5 million from $139,313 for the six months ended
December 31, 1998, to $2.6 million for the six months ended December 31, 1999.
This increase is primarily attributable to an increase in the number of
merchants joining The LinkShare Network(TM) and an increase in the volume and
dollar amount of sales and other activities generated over the network. At
December 31, 1999, we had deferred revenue of $1.1 million relating primarily
to licensing fees.

 Cost of Revenues

   Cost of revenues consists primarily of expenses incurred in operating The
LinkShare Network(TM), including depreciation of servers and related software,
Internet connectivity and technical support costs. Cost of revenues totaled
$16,544 for the six months ended December 31,1998, compared to $407,826 for the
six months ended December 31, 1999. These costs represented 12% of our revenues
for the six months ended December 31, 1998, compared to 16% of our revenues for
the six months ended December 31, 1999. This increase is attributable to an
increase in technical support personnel costs, hosting costs and incremental
depreciation associated with the additional computer hardware and software
required by the increased activity over The LinkShare Network(TM).

 Sales and Marketing

   Sales and marketing expense consists primarily of salaries, commissions and
benefits for client development and marketing personnel, and costs associated
with participating in trade shows, hosting our symposia, public relations and
promotional expenses. Sales and marketing expenses increased by $2.4 million
from $430,161 for the six months ended December 31, 1998, to $2.8 million for
the six months ended December 31, 1999. This increase is primarily attributable
to personnel costs associated with a higher number of employees engaged in
sales and marketing and, to a lesser extent, an increase in public relations,
advertising and symposia costs. We expect these expenses to continue to
increase substantially as we continue expanding our sales and marketing
efforts.

 Product Development

   Product development expense consists primarily of salaries and benefits
provided to employees engaged in our software and new product development. All
product development costs have been expensed as incurred. Product development
expenses increased by $506,222 from $212,354 for the six months ended December
31, 1998, to $718,576 for the six months ended December 31, 1999. This increase
is primarily attributable to increased personnel engaged in product enhancement
and new product development, including such new products as TrafficShare(TM)
and our soon-to-be-launched B2B LinkShare(TM). We believe that continued
investment in software and product development is critical to attaining our
strategic objectives, and we therefore expect product development expenses to
continue increasing.

 General and Administrative

   General and administrative expense consists primarily of employee salaries
and benefits for our executive, administrative, finance, human resource and
business development personnel, professional fees and bad debt expense. General
and administrative expenses increased by $676,216 from $453,724 for the six
months ended December 31, 1998, to $1.1 million for the six months ended
December 31, 1999. This increase is primarily attributable to increased
personnel in our administrative, finance, human resources and business
development departments, the addition of new members to our executive
management team and the leasing of our additional New York City office space.
We expect general and administrative expenses to increase as additional
personnel are hired and additional administrative and managerial activities are
undertaken consistent with the growth of our business.

 Noncash Compensation

   Noncash compensation charges relate to option grants to employees and
represent the excess of the fair value of our common stock on the date of
option grant over the applicable option's exercise price. The charge is
recorded as deferred compensation and expensed over the vesting period of the
option. Noncash compensation charges increased by $158,467 from $92,143 for the
six months ended December 31, 1998, to $250,610 for the six months ended
December 31, 1999. This increase is primarily attributable to the grant of
251,700 options to our employees during the six months ended December 31, 1999.
Additional deferred compensation of $8.9 million, resulting from the grant of
471,636 options in January 2000, will be amortized over the applicable vesting
period of the relevant options.

 Interest Income

   Interest income consists of interest earned on our cash, cash equivalents
and short-term investments. Interest income decreased by $9,695 from $28,344
for the six months ended December 31, 1998, to $18,649 for the six months ended
December 31, 1999.

 Interest Expense

   We had no interest expense for the six months ended December 31, 1998.
Interest expense totaled $549,505 for the six months ended December 31, 1999.
Interest expense consisted primarily of noncash charges of $519,505 related to
the issuance of warrants for the purchase of our common stock, which were
issued from August 1999 through December 1999 in connection with the issuance
of certain convertible notes on August 23, 1999. The interest charge is equal
to the fair value of the warrants at the time of their issuance.

Comparison of the Results of Operation for the Fiscal Years Ended June 30, 1998
and 1999

 Revenues

   Revenues increased by $667,207 from $47,494 for fiscal year 1998 to $714,701
for fiscal year 1999. This increase is primarily attributable to an increase in
the number of merchants joining The LinkShare Network(TM) and an increase in
the volume and dollar amount of sales and other activities generated over the
network.

 Cost of Revenues

   Cost of revenues increased from $12,968 for fiscal year 1998 to $125,432 for
fiscal year 1999. This increase is primarily attributable to an increase in
hosting expense and, to a lesser extent, an increase in technical support
personnel costs and incremental depreciation associated with the additional
computer hardware and software required by the increased activity over The
LinkShare Network(TM). These costs as a percentage of revenues decreased from
27% for fiscal year 1998 to 18% for fiscal year 1999.

                                       20
<PAGE>

 Sales and Marketing

   Sales and marketing expense increased from $41,026 for fiscal year 1998 to
$1.8 million for fiscal year 1999. This increase is attributable to personnel
costs associated with a higher number of employees engaged in sales and
marketing and increased expenditures for public relations, advertising and
symposia.

 Product Development

   Product development expense increased by $517,001 from $103,520 for fiscal
year 1998 to $620,521 for fiscal year 1999. The increase is primarily
attributable to increased personnel engaged in product enhancement and new
product development.

 General and Administrative

   General and administrative expense increased by $1.3 million from $83,408
for fiscal year 1998 to $1.4 million for fiscal year 1999. This increase is
primarily attributable to increased personnel in our administrative, finance,
human resources and business development departments and the addition of new
members to our executive management team, an increase in professional fees and
an increase in bad debt expense.

 Noncash Compensation

   We incurred no noncash compensation charges during fiscal year 1998.
Noncash compensation charges related to employee stock option grants totaled
$203,039 for fiscal year 1999.

 Interest Income

   We had no interest income during fiscal year 1998. Interest income totaled
$61,102 for fiscal year 1999.

 Income Taxes

   We have made no provision for income taxes for the periods presented
because we have incurred losses since our inception. At June 30, 1999, we had
approximately $3.2 million of Federal net operating loss carryforwards. Our
Federal net operating loss carryforwards begin expiring in 2018.

</TABLE>

   Our operating results have varied on a quarterly basis during our short
operating history and may fluctuate significantly in the future. The results of
any quarter do not indicate results to be expected for a full fiscal year. Our
annual or quarterly results of operations may be below the expectations of
public market analysts or investors, in which case the market price of our
common stock could be materially and adversely affected.

Liquidity and Capital Resources

   We have financed our operations to date through the private issuance of
convertible preferred stock, convertible notes and warrants to purchase our
common stock. Through December 31, 1999, net proceeds from financing activities
totaled $6.7 million.

   Net cash provided by operating activities totaled $4,680 for fiscal year
1998 and net cash used in operating activities totaled $2.6 million for fiscal
year 1999 and $659,668 and $1.5 million for the six months ending December 31,
1998, and December 31, 1999, respectively. Cash used in operating activities
for each period consisted primarily of the cash used to fund operating losses
in those periods.

   Net cash used in investing activities totaled $680 for fiscal year 1998,
$1.1 million for fiscal year 1999 and $168,682 and $1.5 million for the six
months ending December 31, 1998, and December 31, 1999, respectively. Net cash
used in investing activities in these periods consisted primarily of capital
expenditures for computer hardware, software and other fixed assets.

                                       22
<PAGE>

   Net cash provided by financing activities totaled $3.9 million for fiscal
year 1999 and $3.9 million and $2.8 million for the six months ending December
31, 1998, and December 31, 1999, respectively. Cash provided by financing
activities was obtained primarily through the private issuance of convertible
preferred stock, convertible notes and warrants to purchase our common stock.

   We believe that the net proceeds from this offering, together with our
existing cash and cash equivalents, will be sufficient to meet our working
capital and capital expenditure requirements for at least the next 15 months.
Thereafter, we may be required to raise additional funds. We may also be
required to raise additional financing before that time. If additional funds
are raised through the issuance of equity securities, our existing stockholders
may experience significant dilution. Furthermore, additional financing may not
be available when needed or may be available only on terms that are not
favorable to us or our stockholders. If additional financing is not available
when needed or is not available on acceptable terms, we may be unable to:

  . develop or enhance our products or services;

  . take advantage of business opportunities; or

  . respond to competitive pressures;

which could have a material and adverse effect on our business, financial
condition or results of operations.

   On February 7, 2000, we issued $6.5 million principal amount of new
convertible promissory notes to our founders and the holders of our Series A
Preferred Stock in exchange for (1) notes previously issued to them on August
23, 1999, and November 18, 1999, (2) a waiver of interest accrued on those
notes and (3) cash advances made by them prior to and contemporaneously with
the issuance of the new notes. Each of the February 2000 notes matures on July
31, 2000, and bears interest at the rate of 6.2% per year, payable upon
maturity. Upon the closing of this offering, each of the notes we issued on
February 7, 2000, will be converted into a number of shares of common stock
determined by dividing the principal amount of those notes plus accrued
interest by 80% of the per-share initial public offering price of our common
stock.

Year 2000 Compliance

   A critical component of our solutions is the accurate tracking and reporting
of activity and transactions within our networks. We believe that all software
that we have developed is Year 2000 compliant. We developed a test environment
to simulate the change over to the Year 2000, and testing of the programs and
procedures related to the processing of data began in March 1999. We tested all
of our various operating systems and hardware platforms to ensure that the date
change would be handled in a correct manner.

   We contacted all of our technology partners to insure Year 2000 compliance
and tested our desktop computers and office equipment to ensure proper
functioning relating to the Year 2000 date change.

   We developed a contingency plan and related tools to facilitate continued
operations in the event of an unanticipated Year 2000 disruption. Our Year 2000
preparedness committee was composed of our Chairman, Chief Information Officer,
Chief Technology Officer and Executive Vice President. The committee reviewed
our compliance efforts and contingency plans.

   No significant disruptions were experienced in LinkShare's operations
related to the Year 2000 date change.

Quantitative and Qualitative Disclosures About Market Risk

   Our exposure to financial market risk, including changes in interest rates
and marketable equity security prices, relates primarily to any investment
portfolio we may hold after this offering. We do not plan to reduce or hedge
our market exposure on any investment securities because, to the extent we
invest in securities, we intend to invest mainly in fixed-rate, short-term
securities. We do not intend to buy or sell any derivative securities. All of
our outstanding indebtedness at December 31, 1999, was fixed-rate debt.

Recent Accounting Pronouncements

   In June 1998, SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities" was issued. SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including derivative
instruments embedded in other contracts, and for hedging activities.
Subsequently, SFAS No. 137 was issued, which deferred the effective date of
SFAS No. 133 to all fiscal quarters of fiscal years beginning after June 15,
2000. SFAS No. 133 is not expected to affect LinkShare, as we do not have any
derivative instruments or hedging activities.

                                  OUR BUSINESS

   LinkShare creates and operates networks that enable businesses to form and
manage online partnerships with thousands of independent Web sites for many
purposes, including selling products and services, building brand-recognition
and increasing Internet-user traffic. Our networks allow online businesses to
find in one convenient, central marketplace a large variety of partners with
whom they can link their Web sites. Our clients use our technology and services
to create and manage their partnerships and track activities through those
links with detailed reports that enable them to evaluate and optimize the
performance of their partnerships.

   Our first network, The LinkShare NetworkTM, offers online merchants and Web
site publishers a performance-based marketing solution that maximizes the
revenue generating power of their Web sites. The LinkShare NetworkTM enables
merchants that sell products or services to consumers over the Internet to
select from thousands of other Web site publishers who seek to convert visitor
traffic into revenues by becoming marketing "affiliates" of those merchants. A
marketing affiliate directs visitor traffic from its own Web site to the
merchant's Web site through a hyperlink promotion appearing on the affiliate's
site. If a visitor who accesses a merchant's Web site through that hyperlink
takes a prescribed action, such as purchasing a product, the affiliate earns a
fee payable by the merchant. We view The LinkShare NetworkTM as a model for
additional networks and applications that we may develop to take advantage of
the growing opportunities offered by the Web.

   Today, The LinkShare NetworkTM has more than 450 participating merchants,
including leading companies like Dell, Toysrus.com, OfficeMax.com, L.L. Bean
and CVS.com, and thousands of independent Web sites that are potential
marketing partners for those merchants. In January 2000, we announced the
creation of B2B LinkShareTM, a separate affiliate network designed to serve the
growing online business-to-business market that we expect to launch by the end
of March 2000. Currently, online businesses use our networks to manage more
than three million online marketing partnerships. Our clients pay us fees that
typically are based on the volume and dollar amount of the transactions and
other activities generated through these partnerships.

Industry Background

 Growth of Online Commerce

   Business use of the Web is growing rapidly as new Web-based businesses and
traditional businesses increasingly use the Internet as a medium to exchange
information and enter into a variety of transactions with customers, suppliers
and distributors. This marketplace consists of businesses selling their
products and services to consumers, commonly referred to as business-to-
consumer commerce, and businesses that use the Web for transactions with other
businesses, commonly referred to as business-to-business commerce. In its
February 2000 report, International Data Corporation predicted that:

  . business-to-consumer spending will grow from $58.6 billion in 2000 to
    $209.1 billion in 2003; and

  . business-to-business spending will grow from $210 billion in 2000 to $1.4
    trillion in 2003.

 Expansion and Fragmentation of the Internet Marketplace

   As e-commerce grows, advertisers and direct marketers increasingly use the
Web to locate customers, advertise and facilitate transactions. To a large
degree, merchants' online marketing efforts are focused on increasing visitors
to their Web sites, which is commonly referred to as Web site "traffic." As a
result of the disaggregated nature of the Web, merchants face significant
challenges in achieving that goal cost-effectively.

   The proliferation of easy-to-use, low-cost Web publishing tools has led to
the creation of millions of Web sites of widely varying content. International
Data estimates that the number of Web pages grew from 303.4 million in 1997 to
2.2 billion in 1999. Nielson/NetRatings estimates that, as of December 1999,
the top ten major Web sites, such as AOL and Yahoo!, accounted for less than
22% of all page views. As a result, online

                                       25
<PAGE>

retailers and Web sites seeking to convert visitor traffic into revenues need a
cost-efficient way to reach the vast majority of page views that are outside
the major Web sites and dispersed over millions of Web sites.

 Early Online Marketing

   Early Web marketing relied primarily on the posting of merchants' banner ads
on independent Web sites. A banner is a graphical rectangular box posted on a
Web site containing advertising material and a hypertext link that permits a
viewer to move from the Web site displaying the ad to the Web site of the
advertiser by "clicking on" the banner. Advertisers generally pay Web sites
carrying their banner ads fees based on the number of impressions, which is the
number of times the Web page displaying the ad is viewed. These fees are
usually fixed at a cost per-thousand (CPM) impressions.

   We believe that traditional banner advertising has proven to be an
inefficient method for converting ad viewers into shoppers and, eventually,
buyers. Only a few content Web sites attract sufficient traffic to generate
significant advertising revenue on a CPM basis, and those few, high-traffic
sites charge increasingly expensive rates for their advertising space. We
believe that the relative effectiveness of traditional banner ads results from
the lack of integration and relevance of traditional banner ads within the
content of the Web sites where they are displayed.

   With the decreasing effectiveness of traditional CPM-based banner
advertising, performance-based marketing methods that tie advertising fees to
tangible results, such as click-throughs, purchases or registrations, represent
the fastest growing segment of the online advertising market. In its August
1999 report, Forrester projects that online advertising spending in the United
States will grow from $2.8 billion in 1999 to $17.2 billion in 2003. Forrester
further projects that performance-based marketing will grow from 15% of all
U.S. online advertising spending in 1999 to over 50% in 2003, creating
significant opportunities for performance-based marketing techniques.

 Emergence of Affiliate Marketing

   "Affiliate marketing" is a performance-based marketing technique that has
emerged in response to the ineffectiveness of early online marketing efforts.
In an affiliate marketing program, a business seeking to attract more traffic
to its Web site to sell goods or services or for other purposes, broadly
referred to as a "merchant," links its Web site to multiple independent Web
sites, usually called "affiliates" of that merchant. These links are embedded
in an affiliate's site and can take the form of a textual mention, banner ad or
other image promoting the merchant or its products. If a visitor to an
affiliate site uses the link to move to the merchant's site and takes a
prescribed action, such as making a purchase or completing a registration form,
the merchant pays a fee to the affiliate. Affiliate marketing enables a
merchant to promote itself across thousands of affiliate Web sites, while only
paying for promotions that actually produce results. Affiliate marketing
enables an affiliate to generate fees by linking its Web site to merchant sites
with products or services likely to be of interest to the affiliate's visitors.

   For most merchants, internally implementing this type of program poses
significant challenges. Developing and maintaining the software and systems
that provide sophisticated linking, updating and tracking capabilities are
expensive and require a high degree of technical expertise. Additionally,
merchants must employ and train personnel to manage all aspects of their
programs, including the identification and screening of potential affiliates,
the negotiation of contracts with potential affiliates and the monitoring of
performance. As a result, many merchants seek a cost-effective solution that
enables them to reap the benefits of an affiliate marketing program without the
costs of self-implementation.

   We recognized early on the opportunities and challenges facing businesses
engaging in online commerce. Our approach was to develop a business model and
the technology to facilitate the creation of link-based partnerships over open
networks available to any individual, business or group with an address on the
Web. Our 1997 launch of The LinkShare NetworkTM to serve the rapidly emerging
business-to-consumer market represents the first application of our business
model.

The LinkShare Solution

   LinkShare creates and operates open online networks that enable businesses
to quickly and easily initiate and monitor multiple relationships through their
Web sites. Our networks enable online businesses to:

  . find appropriate online partners with which to establish relationships;

  . negotiate a wide variety of relationships and customize their
    compensation arrangements;

  . establish links with thousands of Web sites and easily update, remove or
    replace those links; and

  . monitor the traffic through those links and promptly obtain comprehensive
    and detailed reports retrievable from anywhere the Web can be accessed.

 Our Network Model

   Our open or "public" network model provides a business that joins one of our
networks immediate access to the existing members of the network with whom it
can seek to form link-based relationships on mutually agreeable terms. As more
businesses join a network, the costs of maintaining that network are spread
over the growing pool of network members, and the growing pool of network
members becomes an increasingly attractive source of potential business
partners to businesses that have not yet joined. We believe our network model
can be applied to virtually any situation in which a business has a need to
manage relationships with multiple Web sites. We currently operate The
LinkShare NetworkTM and expect to launch B2B LinkShareTM by the end of March
2000. The LinkShare NetworkTM is an affiliate marketing solution for businesses
engaged in business-to-consumer commerce. B2B LinkShareTM will provide a
similar solution for businesses engaged in business-to-business commerce.
Within The LinkShare NetworkTM, we also operate TrafficShareTM, an affiliate
marketing solution for content sites whose primary goal is increasing traffic
to their sites, rather than making sales.

 Technology and Services

   Our LinkShare Synergy(R) technology forms the backbone of our network
solution. It enables multiple Web sites to form links, track the activity
through those links and analyze the results of that activity. Our technology is
easy for our clients to implement, produces prompt and comprehensive tracking
and reporting information and is highly scalable and flexible. We also have a
highly trained staff that provides client support services which enable network
members to optimize the benefits of participation in our networks.

The LinkShare NetworkTM

   The LinkShare NetworkTM is the first and, to date, most significant
application of our open network solution. It brings together online businesses
that participate primarily in business-to-consumer commerce. Online merchants
seeking to sell goods or services to consumers can establish promotional links
across the thousands of affiliate Web sites that belong to The LinkShare
NetworkTM. Both merchant and affiliate members of The LinkShare NetworkTM can
easily find and establish relationships with suitable marketing partners and
manage multiple link-based relationships using our LinkShare Synergy(R)
software and a full suite of support services. Since its launch in 1997, The
LinkShare NetworkTM has grown to over 450 merchants who, as of January 2000,
had established more than three million link-based relationships with affiliate
members of the network. The LinkShare NetworkTM was designed to address the
needs of both merchants and affiliates:

 . Benefits to Merchants

  . Expansive reach of open networks. Merchants can quickly and easily access
    and establish cost-effective marketing partnerships with the thousands of
    eligible affiliates that belong to The LinkShare NetworkTM.

  . Performance-based compensation. Merchants only pay their affiliates for
    carrying a promotional link when that link produces a desired result. Our
    technology gives merchants the flexibility to negotiate a variety of
    performance-based compensation arrangements with their affiliates,
    including percentage-of-sales, CPM, per-form and "hybrid" arrangements
    combining any number of different compensation models.

                                       27

  . Low cost and ease of implementation. Merchants can cost-effectively
    manage multiple online relationships without incurring substantial
    infrastructure or personnel costs and can analyze the effectiveness of
    these relationships with prompt, reliable and comprehensive information
    which can be accessed through any Internet connection.

  . Flexibility and choice. Merchants can choose from among tiers of service
    offerings we provide. Our service offerings enable a merchant member of
    one of our networks to outsource management of its entire affiliate
    marketing program, only certain functions of its program or none at all.

 . Benefits to Affiliates

  . Ability to monetize traffic. Affiliates of all sizes can convert traffic
    on their Web sites into revenues, even when that traffic is insufficient
    to attract significant advertising.

  . One-stop access to quality merchants. Affiliates can quickly and easily
    access and establish relationships with hundreds of quality merchants in
    one open network.

  . Customized compensation arrangements. Affiliates can negotiate
    individualized compensation arrangements with their merchant partners
    based on their performance as marketing partners.

  . Centralized management and tracking. Affiliates can manage multiple
    online relationships with prompt, detailed information provided by a
    neutral third party and accessible from any Web connection.

   Merchants that are members of The LinkShare NetworkTM pay us fees based on
the volume and dollar amount of the transactions and other activities generated
through their links with their affiliates. They also pay us recurring licensing
fees for access to the network and may pay us additional fees for optional
software features and service packages that we offer. Participation in The
LinkShare NetworkTM is free to affiliates.

Our Strategy for Future Growth

   Our goal is to be the premier provider of open networks that facilitate
online commercial activity. Key elements of our growth strategy include:

  . Attracting New Network Participants. We continually seek to attract
    additional businesses to our networks. As a network grows, transaction
    volume over the network increases, as does the pool of network members
    that can benefit from our products and services. As The LinkShare
    NetworkTM expands:

    . each new merchant that joins the network attracts new affiliates by
      its own brand recognition and individual marketing efforts; and

    . the growing pool of easy to identify affiliates becomes an
      increasingly attractive marketing opportunity for merchants not yet
      in the network.

   We believe that because of this self-reinforcing cycle, the addition of a
   single merchant or affiliate increases exponentially the number of new
   business relationships that may be formed on our affiliate networks. We
   have teams of employees dedicated to identifying and recruiting new
   merchants and affiliates to The LinkShare NetworkTM and to our soon-to-
   be-launched B2B LinkShareTM. These teams focus on those merchants with
   widely recognized brand names and high sales volumes and on those
   affiliates with the greatest potential for increasing traffic over our
   networks.

  . Introducing New Affiliate Marketing Networks. We intend to leverage the
    value of our open network model by introducing new affiliate networks
    catering to identifiable business communities. We may introduce these new
    networks specifically for a particular business community, as we will do
    with B2B

                                       28
<PAGE>

   LinkShareTM, an affiliate network focused on business-to-business e-
   commerce. By making B2B LinkShareTM a separate network, we will make it
   easier for business-to-business merchants to find the right affiliates
   without having to screen out thousands of unrelated consumer-oriented
   sites. Alternatively, we may identify members of one of our existing
   networks that have particular business needs and introduce specific
   products or services to serve these needs. In October 1999, we introduced
   TrafficShareTM, an affiliate marketing solution for proprietors of
   advertising-based sites whose primary goal is to drive traffic to their
   sites in order to maintain or increase the rates they charge advertisers.
   TrafficShareTM is currently a feature available to all members of The
   LinkShare NetworkTM, but as the number of businesses using it increases it
   may become a separate network.

   Because each additional network or program that we create is modeled upon
   our existing networks, we can maximize the use of our existing
   infrastructure. Our technology and systems are highly scalable and can
   accommodate increased transactional volume that results from the
   introduction of new networks, products or services.

  . Adapting Our Technology and Network Model for New Uses. We believe that
    our patented technology and expertise in operating affiliate marketing
    networks can be useful in virtually any situation in which businesses
    need to create and manage link-based relationships among multiple Web
    sites, track activities through those links and receive detailed reports
    on the performance of partners in those relationships. As e-commerce
    continues to grow and evolve, we plan to pursue emerging opportunities to
    apply our technology and network model for other uses.

  . Expanding and Enhancing our Products and Services. We seek to develop new
    revenue opportunities by introducing premium software features and
    service packages to existing members of our networks for which we can
    charge additional fees.

  . Introducing Our Solution to International Markets. Just as we can
    introduce our network model to additional business communities, we can
    also introduce it to additional geographic markets. We intend to identify
    suitable international markets for expansion. Our strategy for each
    international market we enter may be different, depending on such factors
    as language, culture and local conditions. We may, for example:

    . directly operate affiliate networks in some markets;

    . form joint ventures with strategic local partners; or

    . license our solution to a third party to operate in a designated
      market.

                                         consumer commerce.

                                         whose primary objective is to increase
                                         traffic to their Web sites, such as
                                         portals and large content sites that
                                         derive most of their revenue by
                                         selling advertising space on their
                                         sites.

   Affiliate members of our networks can access and manage multiple merchant
partnerships in all of the networks they join from a single password-protected
Web site. Merchant members of one network can easily join another network
without any new learning time or significant additional infrastructure costs,
although we may charge them an additional licensing fee. We believe that our
open network platform is superior for most merchants; however, as an adjunct to
our open networks, we offer a private label option for merchants who prefer to
manage some partnerships separately from their participation in the open
network. Merchants using the private label option pay an additional fee to us
for each affiliate recruited into their marketing program from the open
network.

 Technology

   LinkShare Synergy(R). LinkShare Synergy(R) software is the platform on which
we build all of our affiliate networks. We believe LinkShare Synergy(R) is the
most secure, accurate and easy-to-use software available for affiliate
marketing solutions. Use of LinkShare Synergy(R) is included in the network
access fees we charge our merchants. Features of LinkShare Synergy(R) include:

   Web-Based Technology:    . Network participants have immediate access to a
                              full suite of services from any Internet
                              connection.

                            . It requires minimal infrastructure installation
                              because most of the requisite software resides
                              on our servers.

                            . All upgrades occur automatically.

                            . Merchants can update product displays, promote
                              seasonal or limited-time-only offers and replace
                              underperforming links across all affiliate sites
                              with one-click updates.

                            . Affiliates with multiple Web sites can track
                              activity and update links across all sites
                              through a single interface.

   Full Suite of Software Tools:
                            . SmartReports. Network members can monitor the
                              performance of their relationships online
                              through detailed and aggregate data and
                              automated reports that can be delivered by e-
                              mail on specified days.

                            . V-Link. Affiliates can include links to a
                              merchant's site directly in e-mails and send
                              them to potential customers.

                            . Grouping. Merchants can segment or group their
                              affiliate partners and target those segments or
                              groups with individualized e-mails and special
                              offers.

                            . Team Meeting. Merchants can send and receive
                              mail and distribute newsletters over our
                              internal e-mail system or to external addresses,
                              all from one centralized interface.


                            . E-mail Thank You Notes. Automatic e-mailing
                              capabilities allow affiliates to send thank you
                              notes to customers who make purchases on the
                              sites of merchant partners through the
                              affiliate's link.

   Flexibility:             . CustomComp. Merchants can reward or compensate
                              different partners in different ways, such as
                              percentage of sale, CPMs, click-throughs,
                              completed forms, flat fees, return days, monthly
                              minimums or any combination of models.

                            . OpenServe Technology. Merchants can work with
                              any ad-serving technology a merchant chooses,
                              including LinkShare's, through a simple drop-
                              down menu in the interface.

                                       30

   LinkShare Synergy Expert. We offer the LinkShare Synergy Expert software to
our merchant members for a fixed monthly fee. This optional software package
offers an expanded set of tools and features including:

  . SmartTarget. Merchants can recruit particular affiliates by sending
    targeted e-mails to affiliates within the network based on almost any
    criteria, such as site type, geographical region and key word.

  . Affiliate Content Spider. A "control spider" software feature patrols
    affiliate sites automatically, according to a merchant's instructions, to
    detect the use of prohibited words, such as a competitor's name or
    offensive language, or to notify the merchant if an affiliate frames the
    merchant's site without permission.

  . SmartChat. Merchants can schedule chat sessions with affiliates and
    potential affiliates over the network.

 Services and Support

   We work closely with the members of our networks to help them optimize the
value of their affiliate marketing programs. Our members can contact us with
their questions and problems via toll-free telephone number, e-mail and live
online chat sessions. When new merchants join our networks, we provide them
with four hours of free technical support and software training. Additional
support or training is available at hourly rates to merchants that do not
subscribe to one of our optional support packages described below. We also
provide other back-office services, such as e-mail generation and distribution,
check disbursement and 1099 form distribution, for which we charge fees on a
per-message, per-check or per-form basis.

   Merchant members may subscribe to one of our tiered customer service
packages:

  . AE Support. AE Support is designed to help merchants generate better
    response rates by providing analyses of their affiliate marketing
    programs and trends in marketing over the Web. Each merchant that
    subscribes to AE Support is assigned a dedicated account executive to
    assist with initial launch and marketing strategy and participate in
    weekly discussions and six-month formal reviews of the merchant's overall
    program. We provide AE Support free of charge to merchants who generate
    specified transaction volumes over our network, and for a fixed monthly
    fee in the case of merchants that do not achieve the monthly minimum.

  . Client Services. Our Client Services package provides subscribing
    merchants with more comprehensive and in-depth services designed to
    optimize the results of their affiliate marketing programs. This service
    package includes assistance with Web affiliate acquisition and approval,
    affiliate relationship development and management, product merchandising,
    cooperative advertising purchases and back-office services. Our Client
    Services package, when combined with our affiliate payment and other
    back-office service options, permits a merchant to outsource to us
    responsibility for managing virtually all aspects of its affiliate
    marketing program. We typically charge a fixed monthly fee for this
    package and require a subscription for a minimum number of months.

   We also provide services tailored to meet the needs of our affiliate
members:

  . Signature Affiliates. Some of our network affiliates operate loyalty-
    building programs that permit visitors who make a purchase from LinkShare
    merchants with whom those affiliates have links to receive personal
    rewards or credits based on the amount of the purchase. Other affiliates
    make charitable contributions based on visitor purchases from linked
    merchants. Our technology permits us to track transactions through the
    links those affiliates have with our merchants down to the level of
    individual transactions, so that the appropriate amounts can be credited
    to visitors or contributed to the sponsored charity.

  . Best Practices. We continually consult with our affiliates to learn the
    best ways to make our networks work better for them. We organize online
    chat and person-to-person conferences among network participants, and we
    recently completed a comprehensive review of the affiliates in The
    LinkShare NetworkTM that generate high levels of sales or other
    compensated activities for their merchant partners to identify factors
    that contribute to their success. We are implementing programs that will
    permit other affiliates to institute the best practices we have
    identified as a result of that review.

Customers

   Our clients include:

  . businesses selling products and services to consumers and businesses over
    the Web;

  . portals and major content sites seeking to generate advertising revenue;
    and

  . Web publishers that partner with these businesses.

Merchants in our networks include companies with high brand recognition and
significant sales volumes both on and off the Web, as well as medium-sized and
some small merchants. We devote particular attention to recruiting large online
merchants or merchants that are recognized leaders in their industries. Our
goal is to offer members of our networks a selection of potential online
business partners that includes a variety of companies within each major
product or service category. Currently, the vast majority of our clients are
the merchant members of The LinkShare NetworkTM and their affiliate partners
who are engaged primarily in business-to-consumer e-commerce. The table below
lists some of the merchant members of The LinkShare NetworkTM. In addition,
during February 2000, we signed agreements with several new merchants,
including priceline.com and BlueLight.com (Kmart's online store).

   Typically, merchants in our networks enter into written agreements with us
for terms of up to three years that renew automatically for successive terms of
up to two years, unless either party gives notice not to extend. We generally
provide limited warranties concerning our system performance and protection for
our customers from infringement claims. Participating merchants agree to
exclusively use our networks and technology for sales affiliate programs, but
we sometimes permit merchants to maintain pre-existing relationships, to use
their own internal tracking systems for limited purposes or to enter into
business development deals with some Web affiliates.

   Participating affiliates in our networks can discontinue their participation
at anytime. They agree to abide by standard terms of network membership by
completing an online agreement when they register with us, either at our Web
site or at the affiliate recruitment page of the Web site of one of our
merchant members.

Sales and Marketing

 Client Development

   Our merchant development teams, located in New York City, San Francisco,
Chicago and Los Angeles, actively identify and recruit new merchants into our
networks. Our Client Services team, located in Denver, and our account
executives, located primarily in New York City, support our merchant
development teams to market our tiered customer support offerings.

   We also have an affiliate development team, located in New York City, that
actively identifies and recruits new affiliates. All affiliate members of our
networks are affiliates of LinkShare, and we pay them commissions if they
recruit qualified new affiliates into one of our networks.

                                       32

 LinkShare Symposia

   We sponsor periodic LinkShare Symposia in various locations in the United
States and abroad to which we invite a broad spectrum of the e-commerce
community as well as merchant and affiliate members of our networks. Prominent
industry figures speak on topics of general interest, and we organize closed
sessions at which our merchants and affiliates get special training and
information that will help them optimize their use of our solutions and share
the best practices that have been developed by the most successful members of
our networks. These symposia enable us to market our solutions to potential
clients and to strengthen our relationships with the members of our networks.
Attendance has continued to increase since our first Symposium, with over 600
people attending our February 2000 Symposium in San Francisco.

 Advertising and Promotion

   We also market our networks and build awareness of the LinkShare brand
through advertisements within trade and other publications, trade show
participation and other media events and promotional activities.

Technology Infrastructure

 Our Software and Patented Processes

   We have built scalable user interfaces and processing systems that are based
on internally-developed proprietary LinkShare Synergy(R) software. Our network
solutions are Web-based, and there is only a small amount of software for our
merchants to install. The bulk of our software resides on our own servers,
which minimizes both the amount of work and hardware needed by merchants and
Web affiliates to use our solutions and reduces the risk of theft or other
unauthorized copying of our software. To create links on their Web sites, Web
affiliates log in to our systems and then simply "cut and paste" the necessary
code into their Web sites. We work with our members to ensure that they
successfully integrate our technology, and we perform tests to guarantee that
the tracking mechanism is accurate and timely.

   In December 1999, LinkShare was granted U.S. Patent No. 5,991,740 covering
"Data Processing System for Integrated Tracking and Management of Commerce
Related Activities on a Public Access Network." The patent is directed to the
system supporting our affiliate program. It claims a computer system linked to
an array of network-based businesses so that commerce generated by these
businesses may be properly tracked and quantified for reporting purposes. The
patent covers an enhanced programming capability for creating network-based
promotional arrangements and accurately tracking commerce governed by these
promotional arrangements in a non-intrusive manner. While patents issued by the
United States Patent & Trademark office enjoy a presumption of validity, we
cannot assure you that our patent is valid.

 Our Computer Systems

   Our computer systems handle all aspects of our networks, including:

  . the maintenance of our Web site;

  . the formation of links;

  . the collection of new member registration information; and

  . the collection and processing of transaction data needed to furnish
    reports to merchants and affiliates.

Our computer systems are built around industry standard architectures and are
designed to reduce downtime in the event of outages or catastrophic
occurrences. Over the past year, our systems have experienced minimal unplanned
downtime. The servers for our networks provide 24 hour a day, seven day a week
availability, subject to short maintenance periods. During maintenance of our
administrative systems, our members are not able to run reports and perform
other administrative functions, but all e-commerce activity continues to
function normally. We are currently developing a solution that will allow us to
perform routine maintenance on our administrative systems without disrupting
our members' access to administrative functions. We expect this solution to be
in place in the second quarter of 2000.

 Scalability, Availability and Reliability

   Our system infrastructure has been engineered to provide maximum reliability
and availability. We have divided our systems into two groups to make each
group operate at the highest level of availability and to provide the
infrastructure with scalability. The first group, which we refer to as the
"front-end," is responsible for tracking and all related functions that link
merchants with their affiliates. The second group, which we refer to as the
"back-end," is responsible for all administrative tasks, including participant
registrations, reporting and merchant and affiliate program maintenance.

   The front-end systems consist of multiple Intel-based computers running the
Linux operating system. These systems are controlled by redundant geographical
load balancing hardware, and are designed to handle excess loads placed on
them. Since the front-end is designed to function independently of the back-
end, any disruptions to the back-end will have no effect on the front-end.

   The back-end systems run on a combination of Sun Solaris-based systems and
Intel-based multi-processor systems running the Linux operating system. Our
systems allow for quick growth and scalability by enabling us to easily add
additional servers on the back-end for reporting and other administrative
purposes. Since our software is based on industry standards, we are able to
take advantage of new advances in hardware and software in a timely and
efficient manner. We are currently replicating our back-end data over multiple
machines located in geographically dispersed data centers to provide a greater
degree of redundancy in the event of disaster and to distribute the workload
across multiple systems and improve network performance.

   Our system hardware is hosted at the Exodus Communications facility in
Harborside, New Jersey. We also maintain servers at hosting facilities in
Weehawken, New Jersey, New York City, New York, Santa Clara, California and
London, England. Our use of two providers of hosting facilities and the
dispersion of our servers over multiple sites in different regions is intended
to provide redundancy in the event of a natural disaster or other event
affecting any one facility or region. Our hosting facility providers are
contractually obligated to maintain redundant high-capacity Internet
connections, communications lines, emergency power backup, climate-control,
fire protection, seismic reinforcement and continuous security surveillance.

   We regularly test and maintain the multiple connections between our servers,
and regularly test the connections between our network data centers and the
Internet. Our engineering and hosting center personnel monitor traffic patterns
and congestion points and reroute traffic flows to reduce end-user response
times.

Competition

   The market for affiliate marketing solutions, which at present is our only
line of business, is new, rapidly evolving and highly competitive. We compete
against companies of all sizes with respect to the products and services we
provide, and we expect to face increased competition from some of these
companies as they broaden the scope of their products and services.

   We compete with software/service providers, such as Be Free, Inc., that
offer merchants software and services to operate their own private label sales
affiliate programs. These programs can serve as an alternative to the sales
affiliate programs conducted over our networks. Private label providers, such
as Be Free, aggressively market their programs to many of the online merchants
that we may target. We believe that our network model is superior to private
label programs, although some online merchants have expressed a preference for
this structure. For those merchants, we offer a private label option as an
adjunct to membership in our open networks.

   We also compete against other providers operating forms of open networks,
such as Microsoft's LinkExchange and Commission Junction. We believe that
LinkExchange currently focuses on providing exchange services for banner ads
rather than full scale affiliate networks. We believe that Commission Junction
provides its affiliate programs primarily to smaller and midsize merchants.

                                       34
<PAGE>

   To some extent, we also compete with companies that have internally
developed their own affiliate marketing solutions and with independent software
solution providers. Users of third-party software solutions must develop and
maintain databases and servers to track the performance of their marketing
channels.

   We may also compete with companies that provide banner ad services, which
may be considered an alternative marketing solution. However, participants in
our networks are able to use any ad serving technology they choose.

   We believe that the principal competitive factors in our market include:

  . the ease of use of the system;

  . the flexibility and scalability of solutions;

  . technological features; and

  . the quality, comprehensiveness and value of available services.

  We compete with other affiliate marketing providers by:

  . emphasizing the benefits of using an open network model over a
    software/service model or private label program;

  . providing our network members with state-of-the-art technology, such as
    our individualized customer service;

  . providing increasingly comprehensive, cost-effective and easily managed
    solutions; and

  . requiring our merchant members to use LinkShare as their exclusive
    provider for affiliate networks and related technology.

Employees

   At February 24, 2000, we had a total of 139 employees, none of whom are
unionized. From time to time, we also employ independent contractors to
supplement our development staff. We believe our relations with our employees
are good.

Facilities

   Our headquarters are located in 15,000 square feet of office space that we
occupy in New York City under a lease expiring in December 2000. Some of our
personnel are based in 2,370 square feet of separate office space in New York
City that we use under a lease expiring in August 2001. Under a lease expiring
in September 2003, we rent 5,800 square feet of office space in San Francisco,
where we base regional sales and marketing staff. Our Client Services program
is managed from our Denver office, which occupies 5,458 square feet of space
under a lease expiring in December 2000. We have one sales person based in
Chicago and one sales person based in Los Angeles, each of whom works in home
office space. In the future, we may lease additional space as needed.

Legal Proceedings

   From time to time, we may be involved in litigation incidental to the
conduct of our business. We are not currently a party to any legal proceedings.

as directors. We do reimburse them for expenses they incur in attending
meetings of the board and board committees. Non-employee directors are eligible
to receive options to purchase common stock awarded under our stock option
plan. See "--Stock Option Information--LinkShare Corporation Long-Term
Incentive Plan." Upon the closing of this offering, we will grant to each of
Edward P. Gilligan and I. Martin Pompadur, each of whom will be an independent

Employment Agreements

of Stephen D. Messer and Heidi S. Messer that provides for an annual base
salary and an annual merit bonus that may be granted at the discretion of the
board of directors. Each agreement provides for payment to the officer of
accrued and unpaid compensation plus a lump sum equal to six months salary if
the officer's employment is terminated by LinkShare without "cause" or by the
officer with "good cause," as each term is defined in the applicable agreement.

                                       39
<PAGE>

Change of Control Arrangements

   Shares subject to options or restricted stock awards granted under our stock
option plan generally vest over four years, with 25% of the shares vesting
after one year and the remaining shares vesting in equal monthly installments
over the next 36 months. The option agreements under this plan generally
provide accelerated vesting of 50% of the unvested shares subject to the option
upon a change of control that occurs after the first and before the third
anniversary of the award, and full acceleration upon a change of control that
occurs on the termination of employment within two years after a change of
control without "cause" or for "good reason" as defined in the agreement. In
general terms, change of control would occur where any person acquires
ownership of more than 50% of our voting shares or upon any merger or
acquisition where our stockholders before the transaction hold less than a
majority of the voting stock of the surviving entity outstanding after the
transaction.

   We have issued shares of restricted stock or options to certain of our
officers and employees that provide for accelerated vesting of those shares or
options upon a change in control or upon the termination of employment without
"cause" or for "good reason" as defined in the agreement under which those
shares or options were issued.

Stock Option Information

 LinkShare Corporation Long-Term Incentive Plan

   Our board of directors has adopted, and the stockholders have approved, the
LinkShare Corporation Long-Term Incentive Plan in order to provide grants of
options, stock appreciation rights, restricted stock and cash bonuses to our
employees, directors and consultants. The plan authorizes the issuance of a
maximum of 2,576,597 shares of common stock. As of January 31, 2000, options to
purchase 1,625,399 shares had been issued under the plan.

   The compensation committee, which is designated by our board of directors,
administers the plan. This committee has the power to:

  . interpret the plan and adopt any rules, regulations and guidelines for
    carrying out the plan that the committee feels are proper;

  . correct any defect or supply any omission or reconcile any inconsistency
    in the plan or related documents;

                                       40
<PAGE>

  . determine the form and terms of the awards made under the plan, including
    persons eligible to receive the awards, whether awards have been earned
    and the number of shares or other consideration subject to awards; and

  . provide that option exercises may be paid in cash, common stock, a
    portion of any award or a combination thereof.

   The compensation committee may delegate to one or more of our senior
officers some or all of its authority under the plan. However, the committee
may not delegate its authority to grant awards under the plan or take other
action with respect to our officers who are subject to Section 16 of the
Securities Exchange Act of 1934.

   Options. Stock options entitle the holder to purchase a specified number of
shares of our common stock at a specified exercise price, subject to the other
terms and conditions in the option grant. Under present law, however, incentive
stock options and options intended to qualify as performance-based compensation
under Section 162(m) of the tax code may not be granted at an exercise price
less than the fair market value of the common stock on the date of grant (or
less than 110% of the fair market value in the case of incentive stock options
granted to optionees holding more than 10% of the voting power of LinkShare).
Also, incentive stock options may not be granted under the plan after July 16,
2008.

   Stock Appreciation Rights. Stock appreciation rights entitle the recipient
to receive a payment in cash or in stock equal to the excess of the value of
the stock on the day the right is exercised over the price specified in the
grant.

   Stock Award. A stock award may be based on fair market value or other
valuations set by the committee and the exercise of the award may be subject to
conditions set forth in the award agreement, such as:

  . continuous service,

  . achievement of specific business objectives,

  . attaining certain growth rates, or

  . other requirements established by the committee.

   Cash Award. An award may be granted in cash with the amount of future
payment subject to requirements and goals set by the committee.

   Awards Generally. The awards described above may be granted singly, in
combination or in tandem. However, no participant may be granted stock options
or stock appreciation rights exercisable for more than 25% of the shares of
stock authorized under the plan.

   Non-Transferability of Awards. Awards granted under the plan are generally
not transferable by the participant. Each award is exercisable during the
lifetime of the participant only by the participant, and any elections
regarding the awards may be made only by the participant. Except with respect
to incentive stock options, the committee may allow a participant to transfer
an award to certain parties specified by the committee.

   Amendment and Termination of the Plan. Our board of directors may at any
time terminate or amend the plan or any related document, except that our board
of directors may not make any amendments that would impair the rights of any
participant under any award previously granted to the participant or that would
require stockholder approval without obtaining it.

 Option Grants

   We did not grant options during fiscal year 1999 to our Chief Executive
Officer or any executive officer whose compensation exceeded $100,000 during
that fiscal year.

   On August 23, 1999, and November 18, 1999, we sold an aggregate $2.5 million
principal amount of convertible promissory notes to our founders and the
holders of our Series A Preferred Stock for an equal amount of cash. On
February 7, 2000, we issued $6.5 million principal amount of new convertible
promissory notes to those persons in exchange for the notes previously issued
to them, a waiver of interest accrued on those notes and additional cash
advances made by them. Each of the February 2000 notes matures on July 31,
2000, and bears interest at the rate of 6.2% per year, payable upon maturity.
The following table gives the names of the persons to whom we issued the new
notes in February 2000, the principal amount of those notes held by each person
and the consideration paid for each of those notes:

   Upon the closing of this offering, each of the notes we issued on February
7, 2000, will be converted into the number of shares of common stock determined
by dividing the principal amount plus accrued interest by 80% of the per-share
initial public offering price of our common stock.

Warrants

   In connection with the issuance of convertible notes to Comcast Interactive
Capital, we issued to Comcast Interactive Capital warrants to buy shares of our
common stock on the 23rd day of each month beginning on August 23, 1999, and
ending on December 23, 1999. At the date of this prospectus, Comcast
Interactive Capital holds warrants to purchase 41,970 shares of our common
stock. Each of these warrants has a term of five years from the date of
issuance and is exercisable at $1.00 per share. These warrants have a net
exercise provision under which Comcast Interactive Capital may, in lieu of
payment of the exercise price in cash, surrender the warrant and receive a net
amount of shares, based on the fair market value of our common stock at the
time of the exercise of the warrant, after deducting the aggregate exercise
price.

Employment Agreements

   LinkShare has entered into employment agreements with Stephen D. Messer and
Heidi S. Messer. Please see the section of this prospectus titled "Management--
Employment Agreements."

Patent Assignment

   In July 1998, Stephen D. Messer contributed and assigned to LinkShare all of
his rights to the "Data Processing System for Integrated Tracking and
Management of Commerce Related Activities on a Public Access Network" and any
related patents that might be issued.

Other

   Accent Maintenance Corp. is owned by the mother of Stephen D. Messer and
Heidi S. Messer. In the second half of calendar 1999, Accent Maintenance Corp.
performed moving, construction, renovation and other services related to the
relocation of our principal offices in New York City. Accent Maintenance
charged us approximately $863,000 for those services. In addition, since August
1998, we have used Accent Maintenance to provide janitorial, porter,
maintenance and similar services at our New York offices for monthly charges of
up to $6,000 plus the cost of supplies.

                             PRINCIPAL STOCKHOLDERS

   The following table sets forth information with respect to beneficial
ownership of our common stock after the offering by:

  . each person who beneficially owns more than 5% of our common stock;

  . each of our executive officers and directors; and

  . all executive officers and directors as a group.

   We have determined beneficial ownership in accordance with the rules of the
SEC. Unless otherwise indicated, the persons included in the table have sole
voting and investment power with respect to all shares beneficially owned.
Shares of common stock issuable under options, convertible securities or
warrants that are currently exercisable or are exercisable within 60 days of
February 28, 2000 are treated as outstanding and beneficially owned with
respect to the person holding these options for the purpose of computing the
percentage ownership of that person. However, these shares are not treated as
outstanding for purposes of computing the percentage ownership of any other
person. For purposes of this table, we have assumed the automatic conversion of
all of our outstanding shares of preferred stock into 3,242,148 shares of
common stock upon the closing of this offering. This table does not include the
shares of common stock into which our outstanding convertible notes will be
converted upon the closing of this offering. See "Certain Transactions--Bridge
Financings."

<PAGE>

                          DESCRIPTION OF CAPITAL STOCK

   The following is a summary description of our capital stock. We refer you to
our restated certificate of incorporation and bylaws, both of which have been
filed as exhibits to the registration statement, and the applicable provisions
of the Delaware General Corporation Law. Please see the section of this
prospectus titled "Additional Information."

General

   Upon the closing of this offering, our authorized capital stock will consist
of     shares of common stock and     shares of preferred stock, both of which
have a par value of $.001 per share. Assuming the underwriters do not exercise
their over-allotment option, we will have     shares of common stock and no
shares of preferred stock outstanding after the closing of this offering.

Common 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
proportionately any dividends as may be declared by our board of directors,
subject to any preferential dividend rights of outstanding preferred stock.
Upon our liquidation, dissolution or winding up, the holders of common stock
are entitled to receive proportionately our net assets available after the
payment of all debts and other liabilities and subject to the prior rights of
any outstanding preferred stock. Holders of common stock have no preemptive,
subscription, redemption or conversion rights. Our outstanding shares of common
stock are, and the shares offered by us in this offering will be, when issued
and paid for, 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

   The board of directors may issue preferred stock, without stockholder
approval, in such series and with such designations, preferences, conversion or
other rights, voting powers, qualifications, limitations, or restrictions as
the board of directors deems appropriate. While the board of directors has no
current intention of doing so, it could, without stockholder approval, issue
preferred stock with voting and conversion rights which adversely affect the
benefit of any voting power and the benefit of other rights of the holders of
the common stock and which the board of directors could use as an anti-takeover
measure without any further action by the holders of common stock. This may
have the effect of delaying, deferring or preventing a change of control of
LinkShare by increasing the number of shares necessary to gain control of the
company. Except as described below, the board of directors has not authorized
the issuance of any shares of preferred stock and we have no agreements or
current plans for the issuance of any shares of preferred stock.

 Series A Preferred Stock

   As of January 31, 2000 we had issued and outstanding 3,242,148 shares of
Series A Preferred Stock, par value $.001 per share, which will automatically
convert into an aggregate of 3,242,148 shares of common stock upon the closing
of this offering.

Options

   As of January 31, 2000, options to purchase a total of 1,625,399 shares of
common stock were outstanding. The total number of shares of common stock that
may be subject to the granting of options under our stock option plan is equal
to 2,576,597. Please see the sections of this prospectus titled "Management--
Stock Option Information--LinkShare Corporation Long-Term Incentive Plan" and
"Shares Eligible for Future Sale."

                                       45
<PAGE>

   We have outstanding a large number of stock options to purchase our common
stock with exercise prices significantly below the price at which our common
stock is being offered in this offering. The possible sale of a significant
number of those shares by our option holders may have an adverse effect on the
price of the common stock. For a discussion of our intentions with respect to
the registration of the shares underlying these options, see "Shares Eligible
for Future Sale."

Warrants

   As of January 31, 2000, we had issued and outstanding warrants to purchase
41,970 shares of common stock, at an exercise price of $1.00 per share. Of
those warrants, 8,394 will expire on the 23rd day of each month beginning
August 23, 2004. Please see the sections of this prospectus titled "Certain
Transactions-Warrants."

Registration Rights

   Pursuant to the terms of the investor rights agreement that we entered into
with our current stockholders in connection with the issuance and sale of their
stock, as of January 31, 2000, the holders of       shares of common stock are
entitled to certain demand registration rights with respect to the registration
of their shares under the Securities Act. The holders of a majority of these
shares are entitled to demand that we register their shares under the
Securities Act, subject to certain limitations. We are not required to effect
more than two such registrations pursuant to such demand registration rights
and not more than one in any 12 month period. In addition, pursuant to the
terms of the investor rights agreement, the holders of approximately
shares of common stock are entitled to certain piggyback registration rights
with respect to the registration of such shares of common stock under the
Securities Act, subject to certain limitations. Further, at any time after we
become eligible to file a registration statement on Form S-3 certain holders
may require us to file registration statements under the Securities Act on Form
S-3 with respect to their shares of common stock. These registration rights are
subject to certain conditions and limitations, including the right of the
underwriters of an offering to limit the number of shares of common stock held
by security holders with registration rights to be included in such
registration. In addition, holders of these shares will be restricted from
exercising their demand rights for a period of 180 days after the date of this
prospectus. We are generally required to bear all of the expenses of all such
registrations, except underwriting discounts and commissions. Registration of
any of the shares of common stock held by security holders with registration
rights would result in such shares becoming freely tradable without restriction
under the Securities Act immediately upon effectiveness of such registration.

Anti-takeover Effects of Certain 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, as amended from time to time (the DGCL). Subject to certain
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 the interested stockholder attained
such status with the approval of the board of directors or unless the business
combination is approved in a prescribed manner. A "business combination"
includes mergers, asset sales and other transactions resulting in a financial
benefit to the interested stockholder. Subject to certain exceptions, an
"interested stockholder" is a person who, together with affiliates and
associates, owns, or within three years did own, fifteen percent (15%) or more
of the corporation's voting stock. This statute could prohibit or delay the
accomplishment of mergers or other takeover or change in control attempts with
respect to LinkShare and, accordingly, may discourage attempts to acquire
LinkShare.

   In addition, certain provisions of the restated certificate of incorporation
and bylaws, which provisions 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.

                                       46
<PAGE>

 Board of Directors

   Upon the closing of this offering, our board of directors will be divided
into three classes of directors serving staggered three-year terms. As a
result, approximately one-third of the board of directors will be elected each
year. In addition, our restated certificate of incorporation provides that
directors may be removed only for cause by the affirmative vote of the holders
of two-thirds of our shares of capital stock entitled to vote. Our restated
certificate of incorporation further provides that any vacancy on our board of
directors, including a vacancy resulting from an enlargement of our board of
directors, may only be filled by a vote of a majority of our directors then in
office. The classification of our board of directors and the limitations on the
removal of directors and filling of vacancies could make it more difficult for
a third party to acquire, or discourage a third party from acquiring, control
of LinkShare.

 Stockholder Action; Special Meeting of Stockholders

   Our 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. Special meetings of stockholders may be called only
by the chairman of the board of directors or by a majority of the board of
directors.

 Advance Notice Requirements for Stockholder Proposals and Director Nominations

   Our 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 timely notice of
their proposals to the board of directors 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 120 days nor more than 150 days prior
to the first anniversary of the date of the notice of annual meeting we
provided with respect to the previous year's annual meeting of stockholders. 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 60 calendar days after such anniversary, for notice by the
stockholder to be timely, we must receive it not more than 90 days before nor
later than the later of (1) 60 days prior to the annual meeting of stockholders
or (2) the close of business on the 10th day following the date on which notice
of the date of the meeting is given to stockholders or made public, whichever
occurs first. LinkShare's bylaws also specify certain requirements as to the
form and content of a stockholder's notice. These provisions could have the
effect of delaying 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 common stock and preferred stock are
available for future issuance without stockholder approval. We may use these
additional shares 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 render more difficult or discourage an attempt to
obtain control of LinkShare by means of a proxy contest, tender offer, merger
or otherwise.

   The DGCL provides generally that the affirmative vote of a majority of the
shares entitled to vote on any matter is required to amend a corporation's
certificate of incorporation or bylaws, unless a corporation's certificate of
incorporation or bylaws, as the case may be, requires a greater percentage.

Limitation of Liability and Indemnification Matters

   The restated certificate of incorporation provides that, except to the
extent prohibited by the DGCL, our directors shall not be personally liable to
us or our stockholders for monetary damages for any breach of fiduciary duty as
directors of LinkShare. Under the DGCL, the directors have a fiduciary duty to
LinkShare which is not eliminated by this provision of the restated certificate
of incorporation and, in appropriate

                                       47
<PAGE>

circumstances, equitable remedies such as injunctive or other forms of
nonmonetary relief will remain available. In addition, each director will
continue to be subject to liability under the DGCL for breach of the director's
duty of loyalty to LinkShare, for acts or omissions which are found by a court
of competent jurisdiction to be not in good faith or which involve intentional
misconduct, or 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 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. Our restated certificate of incorporation
eliminates the personal liability of directors to the fullest extent permitted
by Section 102(b)(7) of the DGCL and provides that LinkShare shall 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
person:

  .  is or was a director or officer of LinkShare, or

  .  is or was serving at LinkShare's request as a director or officer of:

   .  another corporation,

   .  partnership,

   .  joint venture,

   .  trust, or

   .  other enterprise,

against expenses (including attorney's fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by that person in connection
with the action, suit or proceeding.

   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 our restated certificate of incorporation.
LinkShare is not aware of any threatened litigation or proceeding that may
result in a claim for such indemnification.

Transfer Agent and Registrar

   The transfer agent and registrar for our common stock is HSBC Bank USA.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Before this offering, there has been no public market for our common stock.
Future sales of substantial amounts of our common stock in the public market
following this offering, including shares issued upon exercise of outstanding
options or options that may be granted after this offering, could harm market
prices and could impair our ability to raise capital through the sale of our
equity securities. As described below, less than   % of our shares currently
outstanding will be available for sale immediately after this offering because
of restrictions on resale. Sales of a substantial amount of our common stock in
the public market after the restrictions lapse could adversely affect the
prevailing market price of our common stock and our ability to raise equity
capital in the future.

   Upon the closing of this offering and assuming that none of our outstanding
options are exercised, we will have outstanding     shares of common stock, or
    shares if the underwriters exercise their over-allotment option in full. Of
these outstanding shares,     shares, or     shares if the underwriters
exercise their over-allotment option in full, will be freely tradable without
restriction under the Securities Act, except for shares purchased by our
"affiliates," as that term is defined in Rule 144 under the Securities Act. Any
shares purchased by our affiliates generally may be sold in compliance with
Rule 144 as described below.

   The remaining     shares outstanding are "restricted securities" within the
meaning of Rule 144. Restricted securities may be sold in the public market
only if registered or if they qualify for an exemption from registration under
Rules 144, 144(k) or 701 promulgated under the Securities Act, which are
summarized below. Sales of the restricted securities in the public market, or
the availability of these shares for sale, could adversely affect the market
price of our common stock.

   At January 31, 2000, options for a total of 1,625,399 shares of common stock
had been granted under our stock option plan. Approximately 210,252 of those
options were vested and exercisable at such date. Of those vested shares,
are subject to 180-day lock-up agreements described below.

   We anticipate that our current stockholders will enter into lock-up
agreements or other contractual restrictions providing that they will not
offer, sell, contract to sell or otherwise dispose of any shares of our common
stock for a period of 180 days after the date of this prospectus, without the
prior written consent of Credit Suisse First Boston Corporation. As a result of
these lock-up agreements and other contractual restrictions, notwithstanding
possible earlier eligibility for sale under the provisions of Rule 144, none of
these shares will be resellable until 181 days after the date of this
prospectus. Credit Suisse First Boston Corporation may, in its sole discretion
and at any time without notice, release any portion of the securities subject
to lock-up agreements or other contractual restrictions.

   In general, under Rule 144 as currently in effect, after the expiration of
the lockup agreements, a person who has beneficially owned restricted shares
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:

  .  1% of the number of shares of our common stock then outstanding, which
     will equal approximately     shares immediately after this offering; or

  .  the average weekly trading volume of our common stock during the four
     calendar weeks preceding the sale.

   Sales under Rule 144 are also subject to manner of sale provisions, notice
requirements and the availability of current public information about us. Under
Rule 144(k), a person who is not deemed to have been an affiliate of ours at
any time during the six months preceding a sale, and who has beneficially owned
the shares proposed to be sold for at least two years, is entitled to sell such
shares without complying with the manner of sale, public information, volume
limitation or notice provisions of Rule 144.


                                       49
<PAGE>

   Rule 701 permits our employees, officers, directors or consultants who
purchased shares pursuant to a written compensatory plan or contract to resell
these shares in reliance upon Rule 144 but without compliance with specific
restrictions. Rule 701 provides that affiliates may sell their Rule 701 shares
under Rule 144 without complying with the holding period requirement and that
non-affiliates may sell these shares in reliance on Rule 144 without complying
with the holding period, public information, volume limitation or notice
provisions of Rule 144.

   Following the closing of this offering, we will file a registration
statement on Form S-8 to register shares of our common stock subject to
outstanding options or reserved for future issuance under our stock option
plan. As of January 31, 2000, options to purchase approximately 1,625,399
shares of our common stock were outstanding and approximately 951,198 shares of
our common stock were reserved for future issuance under our stock option plan.
This registration statement will automatically become effective upon filing. As
a result, the common stock issued upon exercise of outstanding vested options,
other than common stock issued to our affiliates, will be available for
immediate resale in the open market, subject to any applicable lock-up
agreement.

   The underwriting agreement provides that the underwriters are obligated to
purchase all the shares of common stock in this offering if any are purchased,
other than those shares covered by the over-allotment option described below.
The underwriting agreement also provides that if an underwriter defaults, the
purchase commitments of non-defaulting underwriters may be increased or this
offering of common stock may be terminated.

   We have granted to the underwriters a 30-day option to purchase on a pro
rata basis up to additional shares from us at the initial public offering price
less the underwriting discounts. The option may be exercised only to cover any
over-allotments of common stock.

   The underwriters propose to offer the shares of common stock initially at
the public offering price on the cover page of this prospectus and to selling
group members at that price less a concession of $    per share. The
underwriters and selling group members may allow a discount of $    per share
on sales to other broker-dealers. After the initial public offering, the public
offering price and concession and discount to broker-dealers may be changed by
the representatives.

   The following table summarizes the compensation and estimated expenses we
will pay:

   The underwriters have informed us that they do not expect discretionary
sales to exceed 5% of the shares of common stock being offered.

   We, our officers, our directors and our stockholders have agreed that we and
they will not offer, sell, contract to sell, announce an intention to sell,
pledge or otherwise dispose of, directly or indirectly, or file with the SEC a
registration statement under the Securities Act relating to any additional
shares of our common stock or securities convertible into or exchangeable or
exercisable for any of our common stock, or publicly disclose the intention to
make any such offer, sale, pledge, disposition or filing, without the prior
written consent of Credit Suisse First Boston Corporation for a period of 180
days after the date of this prospectus, except in our case for issuances
pursuant to the exercise of employee stock options outstanding on the date
hereof.

   The underwriters have reserved for sale, at the initial public offering
price up to shares of our common stock for employees, directors and several
other persons associated with us who have expressed an interest in purchasing
common stock in this offering. The number of shares available for sale to the
general public in this offering will be reduced to the extent these persons
purchase the reserved shares. Any reserved shares not so purchased will be
offered by the underwriters to the general public on the same terms as the
other shares.

   We have agreed to indemnify the underwriters against liabilities under the
Securities Act or contribute to payments which the underwriters may be required
to make in that respect.

   We have applied to list our common stock on The Nasdaq Stock Market's
National Market under the symbol "LNKS."

   Prior to this offering, there has been no public market for our common
stock. The initial public offering price will be determined by negotiation
between our management and representatives of the underwriters. The principal
factors that will be considered in determining the public offering price
include:

  . the information set forth in this prospectus and otherwise available to
    the underwriters;

  . the history and the prospects for the industry in which we will compete;

  . the ability of our management;

  . the prospects for our future earnings;

  . the present state of our development and our current financial condition;

  . the general condition of the securities markets at the time of this
    offering; and

  . the recent market prices of, and the demand for, publicly traded common
    stock of generally comparable companies.

   The representatives may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation
M under the Securities Exchange Act of 1934.

  . Over-allotment involves syndicate sales in excess of this offering size,
    which creates a syndicate short position.

  . Stabilizing transactions permit bids to purchase the underlying security
    so long as the stabilizing bids do not exceed a specified maximum.

  . Syndicate covering transactions involve purchases of the common stock in
    the open market after the distribution has been completed in order to
    cover syndicate short positions.

  . Penalty bids permit the representatives to reclaim a selling concession
    from a syndicate member when the common stock originally sold by the
    syndicate member is purchased in a syndicate covering transaction to
    cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty
bids may cause the price of the common stock to be higher than it would
otherwise be in the absence of these transactions. These transactions may be
effected on The Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.

                          NOTICE TO CANADIAN RESIDENTS

Resale Restrictions

   The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of common stock are effected. Accordingly, any resale of our common
stock in Canada must be made in accordance with applicable securities laws
which will vary depending on the relevant jurisdiction, and which may require
resales to be made in accordance with available statutory exemptions or
pursuant to a discretionary exemption granted by the applicable Canadian
securities regulatory authority. Purchasers are advised to seek legal advice
prior to any resale of the common stock.

Representations of Purchasers

   Each purchaser of common stock in Canada who receives a purchase
confirmation will be deemed to represent to us and the dealer from whom the
purchase confirmation is received that (i) the purchaser is entitled under
applicable provincial securities laws to purchase the common stock without the
benefit of a prospectus qualified under Canadian securities laws; (ii) where
required by law, that the purchaser is purchasing as principal and not as
agent; and (iii) the purchaser has reviewed the text above under "Resale
Restrictions."

Rights of Action for Ontario Purchasers

   The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or rescission or rights of action under the civil liability provisions
of the U.S. federal securities laws.

Enforcement of Legal Rights

   All of the issuer's directors and officers as well as the experts named in
this prospectus may be located outside of Canada and, as a result, it may not
be possible for Canadian purchasers to effect service of process within Canada
upon the issuer or those persons. All or a substantial portion of the assets of
the issuer and those persons may be located outside of Canada and, as a result,
it may not be possible to satisfy a judgment against the issuer or those
persons in Canada or to enforce a judgment obtained in Canadian courts against
the issuer or persons outside of Canada.

Notice to British Columbia Residents

   A purchaser of common stock to whom the Securities Act (British Columbia)
applies is advised that the purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
common stock acquired by the purchaser pursuant to this offering. The report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR #95/17, a copy of which may be obtained from us. Only one report must
be filed in respect of common stock acquired on the same date and under the
same prospectus exemption.

Taxation and Eligibility for Investment

   Canadian purchasers of common stock should consult their own legal and tax
advisors with respect to the tax consequences of an investment in our common
stock in their particular circumstances and with respect to the eligibility of
our common stock for investment by the purchaser under relevant Canadian
legislation.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
LinkShare Corporation:

   We have audited the accompanying balance sheets of LinkShare Corporation as
of June 30, 1998 and 1999, and the related statements of operations,
stockholders' equity (deficit) and cash flows for the years then ended. 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 LinkShare Corporation as of
June 30, 1998 and 1999, and the results of its operations and its cash flows
for the years then ended in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS

                             JUNE 30, 1998 AND 1999
           (All information subsequent to June 30, 1999 is unaudited)

(1) Summary of Operations and Significant Accounting Policies

 (a) Summary of Operations

   LinkShare Corporation ("LinkShare" or the "Company") was incorporated on
July 1, 1997. LinkShare enables the formation of cooperative, performance-based
online business relationships. The Company's networks and technology enable
online businesses to find the right Web sites for those business relationships,
negotiate the terms of their relationships with the publishers of those Web
sites, and evaluate the success of those relationships. The Company's first
network is The LinkShare Network(TM), an affiliate marketing solution that
enables online merchants to establish performance-based relationships with
thousands of Web site publishers who seek to convert visitor traffic into
revenues by becoming marketing "affiliates" of those merchants. The LinkShare
Network(TM) provides affiliate Web sites a quick and easy way to establish
hyperlink promotions with the merchant members of the network to drive traffic
from its site to a merchant's Web site. If a visitor accesses a merchant's Web
site through that hyperlink and takes a prescribed action, such as buying a
product, the affiliate earns a fee payable by that merchant. Merchants pay
LinkShare fees for access to the network and for tracking the activity that
occurs through their links with their marketing affiliates. The Company
operates in one segment, operating online networks and providing software and
services to support those networks.

 (b) Unaudited Interim Financial Information

   The interim financial statements of the Company as of December 31, 1999, and
for the six months ended December 31, 1998 and 1999, are unaudited. Certain
information and note disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to the rules and regulations of the Securities
and Exchange Commission ("SEC") relating to interim financial statements. In
the opinion of management, all adjustments, consisting only of normal recurring
adjustments, necessary for the fair presentation of the financial position, the
results of operations and cash flows have been included in such unaudited
financial statements. The results of operations for the six months ended
December 31, 1999, are not necessarily indicative of the results to be expected
for the entire year.

 (c) 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.

 (d) Cash and Cash Equivalents and Short Term Investments

   The Company considers all highly liquid securities, with original maturities
of three months or less when acquired, to be cash equivalents. Cash
equivalents, consisting of money market accounts, were approximately $0 and
$418,000 at June 30, 1998 and 1999, respectively. Short-term investments at
June 30, 1999, are comprised entirely of U.S. Treasury bills, which matured in
July 1999. Such investments were classified as available for sale and are
carried at amortized cost, which approximates fair value.

 (e) 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, which is three years for computer

                                      F-7
<PAGE>

                             LINKSHARE CORPORATION

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

equipment and software and seven years for office equipment. Leasehold
improvements are amortized over the shorter of the related lease term or the
asset's estimated useful life.

 (f) Other Assets

   At June 30, 1999, other assets include $49,650 of intangible assets, which
are comprised of costs incurred for patents and trademarks related to the
Company's networks and software. Amortization is provided using the straight-
line method over five years. Accumulated amortization was $0 and $6,478 as of
June 30, 1998 and 1999, respectively.

 (g) Income Taxes

   Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to 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.

 (h) Revenue Recognition

   The Company's revenues are derived primarily from software and network
access licensing fees and network fees for services provided to members of the
Company's networks, generally calculated as a percentage of net sales, or fee
per activity, generated through the networks, or from click-throughs,
calculated at a cost per thousand click-throughs ("CPM"). Licensing fees are
deferred at the time of software shipment and billing and recognized as revenue
ratably over the related contractual period the Company provides network
availability. The Company does not perform software installation and
integration services. Network fees are recognized monthly, when earned or when
the applicable service is provided. Cost of revenues primarily consists of the
costs of operating the networks, including depreciation of servers and related
software and Internet connectivity and technical support costs.

 (i) Product Development Costs

   Software development costs incurred subsequent to the establishment of
technological feasibility through general release of products are capitalized
and amortized over the estimated lives of the related products. Technological
feasibility is established upon completion of a working model. To date, the
timing of 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 such costs have not been
significant. All development costs have been charged to product development
expense in the accompanying statements of operations.

 (j) Stock-Based Compensation

   Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting
for Stock-Based Compensation," permits entities to recognize as expense over
the vesting period the fair value of all stock-based awards on the date of
grant or 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 apply the provisions
of APB Opinion No. 25 and records compensation expense for employee stock
options

<PAGE>

                             LINKSHARE CORPORATION

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

for the excess, if any, of the market price of the underlying stock on the date
of grant over the exercise price, and provides the pro forma disclosures.

 (k) Advertising Costs

   The Company expenses the cost of advertising and promoting its services as
incurred.

 (l) 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, short-term
investments, accounts receivable, accounts payable and accrued expenses. At
June 30, 1998 and 1999, the fair value of these instruments approximated their
financial statement carrying amount because of the short-term maturity of these
instruments. No single customer exceeded 10% of either revenue or accounts
receivable for any period presented.

 (m) 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 loss to be recognized is measured by the amount by
which the carrying amount of the assets exceeds the fair value of the assets.

 (n) Basic and Diluted Net Loss Per Share

   Basic earnings per share ("EPS") excludes dilution for common stock
equivalents and is computed by dividing income or loss available to common
stockholders by the weighted average number of common shares outstanding for
the period. Diluted EPS is computed based on the weighted average number of
shares outstanding increased by the potential dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock. Diluted net loss per share is equal to basic net loss per
share for each of the periods presented since all common stock equivalents are
anti-dilutive.

   Potential dilutive shares consist of stock options, convertible preferred
stock, convertible notes payable and warrants. During the year ended June 30,
1998, there were no potentially dilutive common stock equivalents. As of June
30, 1999, there were outstanding preferred shares convertible into 3,242,148
shares of common stock and options to purchase 951,470 shares of common stock.
As of December 31, 1999, there were outstanding preferred shares convertible
into 3,242,148 shares of common stock and options and warrants to purchase
1,195,670 and 41,970 common shares, respectively. In addition, there were notes
payable outstanding that, under differing circumstances, would be convertible
into varying amounts of common stock (see note 9(a)).

 (o) Comprehensive Income (Loss)

   The Company has not presented separate statements of comprehensive income
(loss) since, for all periods presented, comprehensive loss equaled net loss.

 (p) Recent Accounting Pronouncements

   In April 1998, Statement of Position ("SOP") 98-5, "Reporting on the Costs
of Start-Up Activities", was issued 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. The Company adopted SOP 98-5 as
of July 1, 1997.

   In June 1998, SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities" was issued. SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including derivative
instruments embedded in other contracts, and for hedging activities.
Subsequently, SFAS No. 137 was issued, which deferred the effective date of
SFAS No. 133 to all fiscal quarters of fiscal years beginning after June 15,
2000. SFAS No. 133 is not expected to affect the Company, as the Company does
not have any derivative instruments or hedging activities.

 (q) Pro Forma Balance Sheet (unaudited)

   Upon the closing of the Company's planned initial public offering, all of
the outstanding shares of Series A Convertible preferred stock will
automatically convert on a 1-for-1 basis into 3,242,148 shares of common stock
assuming an offering of at least $15 million and an offering price of at least
$4.94 per share. Subsequent to December 31, 1999, the Company received
$3,655,000 from the issuance of the 2000 Notes and stockholder advances and, on
February 7, 2000, all outstanding notes and advances were exchanged for 2000
Notes (see note 9(a)). Upon the closing of the Company's planned initial public
offering, all convertible notes payable will automatically convert into
approximately      shares of common stock, assuming an offering price of $  .
The unaudited pro forma presentation of the balance sheet has been prepared
assuming the issuance of the 2000 Notes, the recording of a charge for the
related beneficial conversion feature and the conversion of the convertible
preferred stock and convertible notes payable into common stock at December 31,
1999.

(3) Capitalization

 Common Stock

   At formation, 200,000 shares of common stock were issued to the Company's
founders. In July 1998, coincidental with the sale of preferred stock, the
Company declared a 20-for-1 common stock split, resulting in 4,000,000 shares
of common stock outstanding. All references to the number of shares of common
stock and per share amounts have been adjusted to reflect the stock split. In
addition, stockholders' equity (deficit) has been restated to give retroactive
recognition to the split in prior periods by reclassifying from additional
paid-in capital to common stock the par value of the additional shares arising
from the split.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


 Preferred Stock

   In July and August 1998, the Company sold in a private placement an
aggregate of 3,242,148 shares of Series A Convertible preferred stock ("Series
A Preferred") at a purchase price of $1.23375 per share. Proceeds, net of
offering costs of $104,320, amounted to $3,895,680. Each share of Series A
Preferred is convertible into one share of common stock, subject to adjustment
for certain events. Shares of Series A Preferred shall automatically be
converted into shares of common stock upon the closing of an underwritten
public offering resulting in gross proceeds to the Company equal to or greater
than $15,000,000 at a price per share of at least $4.94. The Series A Preferred
is not redeemable at the option of the holder or the Company and the purchase
price exceeded the fair value of the Company's common stock on the date of
issuance. The Series A Preferred shares have equal voting rights with the
shares of the Company's common stock.

(4) Stock Options

   In July 1998, the Company established its Long-Term Incentive Plan (the
"Plan"), which provides for the grant of options and stock appreciation rights
and awards to employees, consultants and directors to purchase up to 2,576,597
shares of common stock, as amended. The Plan provides for the granting of
nonqualified and incentive stock options with a duration of ten years or less
from the date of grant. The exercise price for all incentive stock options
shall be no less than 100% of the fair value of common stock at the time of the
grant. The Board of Directors may provide that option exercise prices may be
paid in cash, common stock, or a portion of an award, or any combination
thereof.

   The Company applies APB No. 25 in accounting for its stock options granted
to employees and, accordingly, compensation expense has been recognized in the
financial statements for those nonqualified options issued with exercise prices
less than the fair value of the common stock at the date of grant. During
fiscal 1999, certain of the options granted to employees had exercise prices
less than the fair value of the common stock on the date of grant. Deferred
compensation related to these options was $1,523,524, which is being amortized
over the vesting periods. Compensation expense related to these options was
$203,039 for the year ended June 30, 1999. Had the Company determined
compensation expense based on the fair value at the date of grant for its stock
options granted to employees under SFAS No. 123, the Company's net loss would
have been adjusted to the pro forma amounts indicated below:

</TABLE>

   During the year ended June 30, 1999, the per share weighted average fair
value of stock options granted was $1.81 on the dates of grants using the Black
Scholes option-pricing method with the following assumptions: expected dividend
yield of 0%; risk-free interest rate of 5%; and an expected option life of four
years. As permitted under the provisions of SFAS No. 123, and based on the lack
of a historical public market for the Company's shares, no factor for
volatility has been reflected in the option pricing calculation.

   As of June 30, 1999, the Company had net operating loss carryforwards for
Federal income tax purposes of approximately $3,240,000, expiring in fiscal
2018 and 2019. There can be no assurance that the Company will realize the
benefit of the net operating loss carryforwards.

   Due to the "change of ownership" provisions of Section 382 of the Internal
Revenue Code, the availability of the Company's net operating loss
carryforwards may be subject to an annual limitation against taxable income in
future periods, which could substantially limit the eventual utilization of
these carryforwards.

(6) Commitments and Contingencies:

   The Company leases office space in several locations under agreements
accounted for as operating leases. These leases generally require the Company
to pay all executory costs such as maintenance and insurance.

   Rent expense for the years ended June 30, 1998 and 1999 and for the six
months ended December 31, 1998 and 1999 was approximately $0, $33,000, $14,279
and $322,155, respectively.

   Future minimum lease payments under operating leases are as follows:

executive officers. These agreements will be in effect for two years and may be
terminated by the Company at any time without cause and by the executive
officers under certain conditions.

(9) Subsequent Events--Unaudited

 (a) Convertible Notes Payable

   On August 23, 1999 and November 18, 1999, the Company issued noninterest-
bearing Convertible Promissory Notes (the "1999 Notes") to its common and
Series A Preferred stockholders (collectively the "Lenders"), with an aggregate
principal amount of $1,500,000 and $1,000,000, respectively. Upon the closing
of a preferred stock financing with gross proceeds to the Company of at least
$4 million, the 1999 Notes would

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

have automatically converted into preferred shares similar to those issued in
the preferred stock financing, with the number of shares issued determined by
dividing the principal balance by the price paid by third parties for the
preferred stock. The 1999 Notes were payable on November 23, 1999 and December
31, 1999, respectively. The 1999 Notes were not repaid on their due dates. As a
result, they were due on demand and, commencing from the due dates, began to
accrue interest at 18% per annum.

   In connection with the issuance of the convertible notes in August 1999, the
Company issued warrants to purchase an aggregate of 41,970 shares of common
stock to one of the Lenders. The Company issued the warrants ratably on the
23rd day of each month from August to December 1999. The warrants can be
exercised at $1 per share for five years from the date of issuance. The Company
recorded the fair value of the warrants, amounting to $519,505, as financing
expense for the six months ended December 31, 1999.

   From October 21, 1999 through January 6, 2000, certain of the Company's
common and Series A Preferred stockholders advanced the Company an aggregate of
$1,029,152, of which $345,000 was received by the Company as of December 31,
1999. On February 7, 2000 the Company issued Convertible Promissory Notes to
the Lenders with an aggregate principal amount of $6,500,000 (the "2000
Notes"). The 2000 Notes in an aggregate principal amount of $2,500,000 were
issued in exchange for the 1999 Notes, which were retired and $1,029,152 of the
2000 Notes were issued in exchange for the advances. In addition, the Lenders
waived their right to receive any unpaid interest accrued under the 1999 Notes.
The 2000 Notes are due on July 31, 2000 and bear interest at the rate of 6.2%
per annum. If the Company closes an underwritten initial public offering of its
common stock under the Securities Act of 1933, the 2000 Notes will
automatically convert into that number of common shares determined by dividing
the principal balance, plus accrued interest, by 80% of the price per share at
which common stock is sold to the public. If earlier, upon the closing of a
preferred stock financing with gross proceeds to the Company of at least
$4,000,000, the 2000 Notes shall automatically convert into preferred shares
similar to those issued in the preferred stock financing, with the number of
shares issued determined by dividing the principal balance, plus accrued
interest, by the price per share paid by third parties for the preferred stock.
If the Company is acquired prior to the closing of either of these financings,
the 2000 Notes will be due on demand, repayable at two times the principal
balance.

   Based on the fair value of the common stock on February 7, 2000, the
convertible notes payable had a beneficial conversion feature of $1,625,000,
which will be allocated to additional paid-in-capital and recognized as
interest expense upon the closing of an underwritten initial public offering of
the Company's common stock.

 (b) Options

   During January 2000, the Company granted options to purchase an aggregate of
471,636 shares of the Company's common stock resulting in additional deferred
compensation of $8.9 million, which will be expensed over the options' vesting
periods.

 (c) Authorized Shares

   On February 4, 2000, the Company increased its authorized common shares to
13,000,000.

Item 14. Indemnification of Directors and Officers.

   Section 145 of the Delaware General Corporation Law ("DGCL") provides,
generally, that a corporation shall have the power to 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 (except actions by or in the
right of the corporation) by reason of the fact that such person is or was a
director, officer, employee or agent of the corporation against all expenses,
judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such action, suit or proceeding if
such person acted in good faith and in a manner such person reasonably believed
to be in or not opposed to the best interests of the corporation and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe his or her conduct was unlawful. A corporation may similarly indemnify
such person for expenses actually and reasonably incurred by such person in
connection with the defense or settlement of any action or suit by or in the
right of the corporation, provided such person acted in good faith and in a
manner he or she reasonably believed to be in or not opposed to the best
interests of the corporation, and, in the case of claims, issues and matters as
to which such person shall have been adjudged liable to the corporation,
provided that a court shall have determined, upon application, that, despite
the adjudication of liability but in view of all of the circumstances of the
case, such person is fairly and reasonably entitled to indemnity for such
expenses which such court shall deem proper.

   Section 102(b)(7) of the DGCL provides, generally, that the certificate of
incorporation may contain a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such
provision may 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) under section 174
of Title 8 of the Delaware General Corporation Law, or (iv) for any transaction
from which the director derived an improper personal benefit. No such provision
may eliminate or limit the liability of a director for any act or omission
occurring prior to the date when such provision became effective.

                                      II-1
<PAGE>

   Upon the closing of this offering, Article V, Section E of the Restated
Certificate of Incorporation, as amended ("LinkShare charter"), of LinkShare
Corporation, a Delaware corporation ("LinkShare"), will provide as follows:

1. Limitation on Liability

   To the fullest extent permitted by the DGCL as the same exists or may
hereafter be amended, a director of LinkShare shall not be liable to LinkShare
or any of its stockholders for monetary damages for breach of fiduciary duty as
a director. Any repeal or modification of this subparagraph 1 shall be
prospective only and shall not adversely affect any limitation, right or
protection of a director of LinkShare existing at the time of such repeal or
modification.

2. Indemnification

   (a) Right to Indemnification. LinkShare shall indemnify and hold harmless,
to the fullest extent permitted by applicable law as it presently exists or may
hereafter be amended, any person who was or is made or is threatened to be made
a party or is otherwise involved in any action, suit or proceeding, whether
civil, criminal, administrative or investigative (a "proceeding") by reason of
the fact that he, or a person for whom he is the legal representative, is or
was a director or officer of LinkShare or is or was serving at the request of
LinkShare as a director, officer, employee or agent of another corporation or
of a partnership, limited liability company, joint venture, trust, enterprise
or nonprofit entity, including service with respect, to employee benefit plans,
against all liability and loss suffered and expenses (including attorneys'
fees) reasonably incurred by such person. Such right of indemnification shall
inure whether or not the claim asserted is based on matters which antedate the
adoption of this Section E. LinkShare shall be required to indemnify a person
in connection with a proceeding (or part thereof) initiated by such person only
if the proceeding (or part thereof) was authorized by the Board of Directors of
LinkShare.

   (b) Prepayment of Expenses. LinkShare shall pay the expenses (including
attorneys' fees) incurred by a director or officer in defending any proceeding
in advance of its final disposition, provided, however, that the payment of
expenses incurred by a director or officer in advance of the final disposition
of the proceeding shall be made only upon receipt of an undertaking by the
director or officer to repay all amounts advanced if it should be ultimately
determined that the director or officer is not entitled to be indemnified under
this subparagraph 2 or otherwise.

   (c) Claims. If a claim for indemnification or payment of expenses under this
subparagraph 2 is not paid in full within 60 days after a written claim
therefor has been received by LinkShare, the claimant may file suit to recover
the unpaid amount of such claim and, if successful in whole or in part, shall
be entitled to be paid the expense of prosecuting such claim. In any such
action LinkShare shall have the burden of proving that the claimant was not
entitled to the requested indemnification or payment of expenses under
applicable law.

   (d) Non-Exclusivity of Rights. The rights conferred on any person by this
subparagraph 2 shall not be exclusive of any other rights which such person may
have or hereafter acquire under any statute, provision of this Certificate, the
Bylaws, agreement, vote of stockholders or disinterested directors or
otherwise.

   (e) Other Indemnification. LinkShare's obligation, if any, to indemnify any
person who was or is serving at its request as a director, officer, employee or
agent of another corporation, partnership, limited liability company, joint
venture, trust, enterprise or nonprofit entity shall be reduced by any amount
such person may collect as indemnification from such other corporation,
partnership, limited liability company, joint venture, trust, enterprise or
nonprofit entity.

3. Amendment or Repeal

   Any repeal or modification of the foregoing provisions of this Section E
shall not adversely affect any right or protection hereunder of any person in
respect of any act or omission occurring prior to the time of such repeal or
modification."

Item 15. Recent Sales of Unregistered Securities.

     (a) On July 18, 1997, LinkShare issued and sold an aggregate of
  4,000,000 shares of its common stock to Stephen D. Messer, Heidi S. Messer
  and Jianhao Meng for an aggregate purchase price of $200 and fixed assets
  with a fair value of $37,924.

     (b) On July 16, 1998, LinkShare issued and sold 2,431,611 shares of
  Series A Preferred Stock to Internet Capital Group, LLC for $3,000,000.

     (c) On August 28, 1998, LinkShare issued and sold 810,537 shares of
  Series A Preferred Stock to Comcast Internet Investments I, Inc. for
  $1,000,000.

     (d) On August 23, 1999, LinkShare issued and sold (1) convertible notes
  having an aggregate face value of $1,500,000 to Stephen D. Messer, Heidi S.
  Messer, Jianhao Meng, Internet Capital Group, Inc. and Comcast Internet
  Investments I, Inc., for an aggregate purchase price of $1,500,000.
  Pursuant to the terms of the notes purchased by Comcast Internet
  Investments I, LinkShare issued warrants to purchase an aggregate of 41,970
  shares of common stock at an exercise price of $1.00 per share to Comcast
  Interactive Capital, L.P., as successor in interest to Comcast Internet
  Investments I, Inc. The warrants were issued ratably on the 23rd day of
  each month from August to December 1999.

     (e) On November 18, 1999, LinkShare issued and sold convertible notes
  having an aggregate face value of $1,000,000 to Internet Capital Group,
  Inc. and Comcast Interactive Capital, LP. for an aggregate purchase price
  of $1,000,000.

     (f) On February 7, 2000, LinkShare issued and sold convertible notes
  having an aggregate face value of $6,500,000 to Stephen D. Messer, Heidi S.
  Messer, Jianhao Meng, Internet Capital Group, Inc. and Comcast Interactive
  Capital, LP. The consideration for those notes consisted of the surrender
  of the August 1999 and November 1999 convertible notes issued to such
  persons, waiver of interest accrued under those notes plus cash advances
  equal to the difference between the aggregate principal amount of the notes
  surrendered and the aggregate principal amount of the February 2000 notes.

   None of the foregoing transactions involved any underwriters, underwriting
discounts or commissions, or any public offering, and LinkShare believes that
each transaction was exempt from the registration requirements of the
Securities Act by virtue of Section 4(2) thereof. The first transaction listed
was the initial capitalization of LinkShare by its founders. In each other
transaction the recipients of LinkShare securities represented to LinkShare
that they were acquiring the securities for investment only and not with a
view to the sale or distribution thereof. Appropriate legends were affixed to
the share certificates or other instruments issued in each transaction. Each
recipient of LinkShare securities had adequate access to information about
LinkShare and the securities acquired through that recipient's relationship
with LinkShare.

   (b) Financial Statement Schedules. Schedules not listed above have been

Item 17. Undertakings.

   (a) LinkShare hereby undertakes to provide to the underwriter at the closing
specified in the underwriting agreements, certificates in such denominations
and registered in such names as required by the underwriter to permit prompt
delivery to each purchaser.

   (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
LinkShare pursuant to the foregoing provisions, or otherwise, LinkShare has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by LinkShare
of expenses incurred or paid by a director, officer or controlling person of
LinkShare 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, LinkShare will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act of 1933 and will be
governed by the final adjudication of such issue.

   (c) LinkShare hereby undertakes that:

     (1) For purposes of determining any liability under the Securities Act
  of 1933, the information omitted from the form of prospectus filed as part
  of this registration statement in reliance upon Rule 430A and contained in
  a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.

     (2) For the purpose of determining any liability under the Securities
  Act of 1933, each post-effective amendment that contains a form of
  prospectus shall be deemed to be a new registration statement relating to
  the securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

                             LINKSHARE CORPORATION


          LINKSHARE CORPORATION, a corporation organized and existing under the
laws of the State of Delaware, hereby certifies as follows:

     (1) The name of the Corporation is LinkShare Corporation. The original
Certificate of Incorporation of the Corporation was filed on July 1, 1997. The
name under which the Corporation was originally incorporated is "LinkShare
Technologies Corp."

     (2) This Certificate of Amendment amends the provisions of the Certificate
of Incorporation of the Corporation, as previously amended and restated by a
Restated Certificate of Incorporation dated July 16, 1998, to increase the
number of authorized shares of Common Stock of the Corporation.

     (3) The Board of Directors of the Corporation duly adopted, by unanimous
written consent in accordance with Section 141 of the Delaware General
Corporation Law, resolutions that (i) set forth a proposed amendment of the
Restated Certificate of Incorporation of the Corporation, (ii) declared said
amendment to be advisable and in the best interests of the Corporation and (iii)
directed that such amendment be submitted to the stockholders of the Corporation
for consideration thereof. The text of the resolution setting forth the proposed
amendment is as follows:

          RESOLVED, that Part A of Article IV of the Corporation's Restated
     Certificate of Incorporation shall, subject to requisite stockholder
     approval, be amended to read in its entirety as follows:

               "A. This Corporation is authorized to issue two classes of stock
     to be designated, respectively, 'Common Stock' and 'Preferred Stock.' The

     The name of the corporation is LINKSHARE CORPORATION (the "Corporation" or

     A. This Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock." The total number
of shares which the Corporation is authorized to issue is Thirteen Million Seven
Hundred Fifty Thousand (13,750,000) shares, Ten Million (10,000,000) shares of

                                       1
<PAGE>

     B. Upon the effective date of this Amended and Restated Certificate of
Incorporation each outstanding share of Common Stock shall be split and
reconstituted into 20 shares of Common Stock. Each of such shares of Common
Stock shall be fully paid and nonassessable. Effective as of such date, each
stock certificate that, immediately prior to such split and reconstitution,
evidenced any shares of the Corporation's Common Stock as then constituted (an
"Existing Certificate") shall continue to be valid and shall evidence ownership
of 20 times the number of shares of Common Stock enumerated thereon, and no
surrender for any notation upon, change in or exchange, substitution or
surrender of, any such certificate shall be required by virtue of such split or
reconstitution. Each holder of an Existing Certificate, however, shall be
entitled upon surrender of such Existing Certificate to the Corporation for
cancellation to receive one or more new certificates that in the aggregate
represent the full number of shares of Common Stock into which the issued and
outstanding shares of Common Stock evidenced thereby have been split and
reconstituted as provided herein.

     C. The number of authorized shares of Common Stock may be increased or
decreased (but not below the number of shares of Common Stock then outstanding)
by the affirmative vote of the holders of a majority of the stock of the
Corporation (voting together on an as-if-converted basis).

     D. Three Million Two Hundred Fifty Thousand (3,250,000) of the authorized
shares of Preferred Stock are hereby designated "Series A Preferred Stock" (the
"Series Preferred").

     E. The rights, preferences, privileges, restrictions and other matters
relating to the Series Preferred are as follows:

          1. DIVIDEND RIGHTS.

               a. Holders of Series Preferred, in preference to the holders of
          any other stock of the Company ("Junior Stock"), shall be entitled to
          receive, when, as and if declared by the Board of Directors, but only
          out of funds that are legally available therefor, cash dividends at
          the rate of eight percent (8%) of the "Original Issue Price" per annum
          on each outstanding share of Series Preferred (as adjusted for any
          stock dividends, combinations, splits, recapitalizations and the like
          with respect to such shares). The Original Issue Price of the Series
          Preferred shall be $1.23375 (as adjusted for any stock dividends,
          combinations, splits, recapitalizations and the like with respect to
          such shares). Such dividends shall be payable only when, as and if
          declared by the Board of Directors and shall be non-cumulative.

               b. So long as any shares of Series Preferred shall be
          outstanding, no dividend, whether in cash or property, shall be paid
          or declared, nor shall any other distribution be made, on any Junior
          Stock, nor shall any shares of any Junior Stock of the Company be
          purchased, redeemed, or otherwise acquired for value by the Company
          (except for acquisitions of Common Stock by the Company pursuant to
          agreements which permit the Company to repurchase such shares upon
          termination of services to the Company or in exercise of the Company's
          right of first refusal upon a proposed transfer) until all dividends
          (set forth in Section 1a above) on the Series Preferred shall have
          been paid or declared and set apart. In the event dividends are paid
          on any share of Common Stock, an additional dividend shall be paid
          with

                                       2
<PAGE>

          respect to all outstanding shares of Series Preferred in an amount
          equal per share (on an as-if-converted to Common Stock basis) to the
          amount paid or set aside for each share of Common Stock. The
          provisions of this Section 1b shall not, however, apply to (i) a
          dividend payable in Common Stock, (ii) the acquisition of shares of
          any Junior Stock in exchange for shares of any other Junior Stock, or
          (iii) any repurchase of any outstanding securities of the Company that
          is unanimously approved by the Company's Board of Directors.

          2. VOTING RIGHTS.

               a. General Rights. Except as otherwise provided herein or as
          required by law, the Series Preferred shall be voted equally with the
          shares of the Common Stock of the Company and not as a separate class,
          at any annual or special meeting of shareholders of the Company, and
          may act by written consent in the same manner as the Common Stock, in
          either case upon the following basis: each holder of shares of Series
          Preferred shall be entitled to such number of votes as shall be equal
          to the whole number of shares of Common Stock into which such holder's
          aggregate number of shares of Series Preferred are convertible
          (pursuant to Section 4 hereof) immediately after the close of business
          on the record date fixed for such meeting or the effective date of
          such written consent.

               b. Separate Vote of Series Preferred. For so long as at least
          Five Hundred Thousand (500,000) shares of Series Preferred (subject to
          adjustment for any stock split, reverse stock split or other similar
          event affecting the Series Preferred) remain outstanding, in addition
          to the vote or written consent of the holders of at least a majority
          of the Common Stock (as a separate class) or any other vote or consent
          required herein or by law, the vote or written consent of the holders
          of at least a majority of the outstanding Series Preferred shall be
          necessary for effecting or validating the following actions:

                    (i) Any amendment, alteration, or repeal of any provision of
               the Certificate of Incorporation or the Bylaws of the Company
               (including any filing of a Certificate of Designation), that
               adversely alters or changes the voting powers, preferences, or
               other special rights or privileges, or restrictions of the Series
               Preferred;

                    (ii) Any increase or decrease (other than by redemption or
               conversion) in the authorized number of shares of Preferred
               Stock;

                    (iii) Any authorization or any designation, whether by
               reclassification or otherwise, of any new class or series of
               stock or any other securities convertible into equity securities
               of the Company having rights, preferences, or privileges ranking
               on a parity with or senior to the Series Preferred or any
               increase in the authorized or designated number of any such new
               class or series;

                    (iv) Any redemption, repurchase or other distributions with
               respect to Junior Stock (except for acquisitions of Common Stock
               by the Company pursuant to agreements which permit the Company to
               repurchase such shares upon termination of services to the
               Company or in exercise of the Company's right of first refusal
               upon a proposed transfer);

                                       3
<PAGE>

                    (v) Any Asset Transfer or Acquisition (each as defined in
               Section 3d);

                    (vi) The payment or declaration of a dividend on any shares
               of Common Stock or Preferred Stock;

                    (vii) Any voluntary dissolution or liquidation of the
               Company; or

                    (viii) Any increase or decrease in the authorized number of
               members of the Company's Board of Directors.

               c. Election of Board of Directors. For so long as at least Five
          Hundred Thousand (500,000) shares of Series Preferred remain
          outstanding (subject to adjustment for any stock split, reverse stock
          split or similar event affecting the Series Preferred), (i) the
          holders of Series Preferred, voting as a separate class, shall be
          entitled to elect two (2) members of the Company's Board of Directors
          at each meeting or pursuant to each consent of the Company's
          shareholders for the election of directors, and to remove from office
          such directors and to fill any vacancy caused by the resignation,
          death or removal of such directors; (ii) the holders of Common Stock,
          voting as a separate class, shall be entitled to elect two (2) members
          of the Board of Directors at each meeting or pursuant to each consent
          of the Company's shareholders for the election of directors, and to
          remove from office such directors and to fill any vacancy caused by
          the resignation, death or removal of such directors; and (iii) the
          holders of Common Stock and Series Preferred, voting together as a
          class, shall be entitled to elect all remaining members of the Board
          of Directors at each meeting or pursuant to each consent of the
          Company's shareholders for the election of directors, and to remove
          from office such directors and to fill any vacancy caused by the
          resignation, death or removal of such directors.

               As of the first date that the number of Series Preferred
          outstanding falls below the minimum required by the first sentence of
          this subsection, the right of the holders of the Series Preferred to
          nominate, appoint, vote for or vote in the election of any directors
          of the Company shall automatically terminate; the terms of office of
          the directors elected by the Series Preferred pursuant to Section 2(c)
          above then serving on the Company's Board of Directors shall
          automatically terminate; and the vacancies on the Board thereby
          created shall be filled by solely by the vote of the holders of the
          then outstanding Common Stock (without any separate vote on the part
          of the holders of the Series Preferred). Nothing contained in this
          Section is intended or shall be construed as preventing, impairing or
          otherwise affecting the right of any holders of the Common Stock from
          agreeing among themselves or with any holders of the Series Preferred
          as to the manner in which their respective shares of capital stock of
          the Company shall be voted with respect to the composition of the
          Company's Board of Directors, the nomination or election of directors
          or any other matter, which right is hereby confirmed.

               d. No Other Class Votes. Except as expressly provided in this
          Section 4 above and except as required by the Delaware General
          Corporation Law, the holders of the Series Preferred will not have any
          right to vote, give consents or otherwise take or approve
                                       4
<PAGE>

     action as a separate class or series with respect to any matter coming
     before the stockholders of the Company.

     3. LIQUIDATION RIGHTS.

          a. Upon any liquidation, dissolution, or winding up of the Company,
     whether voluntary or involuntary, before any distribution or payment shall
     be made to the holders of any Junior Stock, the holders of Series Preferred
     shall be entitled to be paid out of the assets of the Company an amount per
     share of Series Preferred equal to the Original Issue Price plus all
     declared and unpaid dividends on the Series Preferred Stock (as adjusted
     for any stock dividends, combinations, splits, recapitalizations and the
     like with respect to such shares) for each share of Series Preferred held
     by them.

          b. After the payment of the full liquidation preference of the Series
     Preferred as set forth in Section 3a above, the assets of the Company
     legally available for distribution, if any, shall be distributed ratably to
     the holders of the Common Stock and Series Preferred on an as-if-converted
     to Common Stock basis.

          c. If, upon any liquidation, distribution, or winding up, the assets
     of the Company shall be insufficient to make payment in full to all holders
     of Series Preferred of the liquidation preference set forth in Section 3a,
     then such assets shall be distributed among the holders of Series Preferred
     at the time outstanding, ratably in proportion to the full amounts to which
     they would otherwise be respectively entitled.

          d. The following events shall be considered a liquidation under this
     Section:

               (i) any consolidation or merger of the Company with or into any
          other corporation or other entity or person, or any other corporate
          reorganization, in which the stockholders of the Company immediately
          prior to such consolidation, merger or reorganization, own less than
          50% of the Company's outstanding capital stock (on an as-converted to
          Common Stock basis) immediately after such consolidation, merger or
          reorganization, or any transaction or series of related transactions
          to which the Company is a party in which in excess of fifty percent
          (50%) of the Company's outstanding capital stock (on an as-converted
          to Common Stock basis) is transferred (an "Acquisition"); or

               (ii) a sale, lease or other disposition of all or substantially
          all of the assets of the Company (an "Asset Transfer").

          e. In any of such liquidation events, if the consideration received by
     the Company is other than cash, its value will be deemed its fair market
     value as determined in good faith by the Board of Directors. Any securities
     shall be valued as follows:

               (i) Securities not subject to investment letter or other similar
          restrictions on free marketability covered by (ii) below:

                                       5
<PAGE>

                    (A) If traded on a securities exchange or through the Nasdaq
               National Market, the value shall be deemed to be the average of
               the closing prices of the securities on such quotation system
               over the thirty (30) day period ending three (3) days prior to
               the closing;

                    (B) If actively traded over-the-counter, the value shall be
               deemed to be the average of the closing bid or sale prices
               (whichever is applicable) over the thirty (30) day period ending
               three (3) days prior to the closing; and

                    (C) If there is no active public market, the value shall be
               the fair market value thereof, as determined by the Board of
               Directors.

               (ii) The method of valuation of securities subject to investment
          letter or other restrictions on free marketability (other than
          restrictions arising solely by virtue of a stockholder's status as an
          affiliate or former affiliate) shall be to make an appropriate
          discount from the market value determined as above in (i) (A), (B) or
          (C) to reflect the approximate fair market value thereof, as
          determined by the Board of Directors.

          4. CONVERSION RIGHTS.

               The holders of the Series Preferred shall have the following
          rights with respect to the conversion of the Series Preferred into
          shares of Common Stock (the "Conversion Rights"):

                    a. Optional Conversion. Subject to and in compliance with
               the provisions of this Section 4, any shares of Series Preferred
               may, at the option of the holder, be converted at any time into
               fully-paid and nonassessable shares of Common Stock. The number
               of shares of Common Stock to which a holder of Series Preferred
               shall be entitled upon conversion shall be the product obtained
               by multiplying the "Series Preferred Conversion Rate" then in
               effect (determined as provided in Section 4b) by the number of
               shares of Series Preferred being converted.

                    b. Series Preferred Conversion Rate. The conversion rate in
               effect at any time for conversion of the Series Preferred (the
               "Series Preferred Conversion Rate") shall be the quotient
               obtained by dividing the Original Issue Price of the Series
               Preferred by the "Series Preferred Conversion Price," calculated
               as provided in Section 4c.

                    c. Series Preferred Conversion Price. The conversion price
               for the Series Preferred shall initially be the Original Issue
               Price of the Series Preferred (the "Series Preferred Conversion
               Price"). Such initial Series Preferred Conversion Price shall be
               adjusted from time to time in accordance with this Section 4. All
               references to the Series Preferred Conversion Price herein shall
               mean the Series Preferred Conversion Price as so adjusted.

                    d. Mechanics of Conversion. Each holder of Series Preferred
               who desires to convert the same into shares of Common Stock
               pursuant to this Section 4 shall surrender the certificate or
               certificates therefor, duly endorsed, at the office of the
               Company or

                                       6
<PAGE>

               any transfer agent for the Series Preferred, and shall give
               written notice to the Company at such office that such holder
               elects to convert the same. Such notice shall state the number of
               shares of Series Preferred being converted. Thereupon, but
               subject the Section 4(t) below, the Company shall promptly issue
               and deliver at such office to such holder a certificate or
               certificates for the number of shares of Common Stock to which
               such holder is entitled and shall promptly pay in cash or, to the
               extent sufficient funds are not then legally available therefor,
               in Common Stock (at the Common Stock's fair market value
               determined by the Board of Directors as of the date of such
               conversion), any declared and unpaid dividends on the shares of
               Series Preferred being converted. Such conversion shall be deemed
               to have been made at the close of business on the date of such
               surrender of the certificates representing the shares of Series
               Preferred to be converted, and the person entitled to receive the
               shares of Common Stock issuable upon such conversion shall be
               treated for all purposes as the record holder of such shares of
               Common Stock on such date.

                    e. Adjustment for Stock Splits and Combinations. If the
               Company shall at any time or from time to time after the date
               that the first share of Series Preferred is issued (the "Original
               Issue Date") effect a subdivision of the outstanding Common Stock
               without a corresponding subdivision of the Preferred Stock, the
               Series Preferred Conversion Price in effect immediately before
               that subdivision shall be proportionately decreased. Conversely,
               if the Company shall at any time or from time to time after the
               Original Issue Date combine the outstanding shares of Common
               Stock into a smaller number of shares without a corresponding
               combination of the Preferred Stock, the Series Preferred
               Conversion Price in effect immediately before the combination
               shall be proportionately increased. Any adjustment under this
               Section 4e shall become effective at the close of business on the
               date the subdivision or combination becomes effective.

                    f. Adjustment for Common Stock Dividends and Distributions.
               If the Company at any time or from time to time after the
               Original Issue Date makes, or fixes a record date for the
               determination of holders of Common Stock entitled to receive, a
               dividend or other distribution payable in additional shares of
               Common Stock, in each such event the Series Preferred Conversion
               Price that is then in effect shall be decreased as of the time of
               such issuance or, in the event such record date is fixed, as of
               the close of business on such record date, by multiplying the
               Series Preferred Conversion Price then in effect by a fraction
               (i) the numerator of which is the total number of shares of
               Common Stock issued and outstanding immediately prior to the time
               of such issuance or the close of business on such record date,
               and (ii) the denominator of which is the total number of shares
               of Common Stock issued and outstanding immediately prior to the
               time of such issuance or the close of business on such record
               date plus the number of shares of Common Stock issuable in
               payment of such dividend or distribution; provided, however, that
               if such record date is fixed and such dividend is not fully paid
               or if such distribution is not fully made on the date fixed
               therefor, the Series Preferred Conversion Price shall be
               recomputed accordingly as of the close of business on such record
               date and thereafter the Series Preferred Conversion Price shall
               be adjusted pursuant to this Section 4f to reflect the actual
               payment of such dividend or distribution.

                    g. Adjustments for Other Dividends and Distributions. If the
               Company at any time or from time to time after the Original Issue
               Date makes, or fixes a record date for the determination of
               holders of Common Stock entitled to receive, a dividend or other
               distribution payable in securities of the Company other than
               shares of Common Stock, in each such event provision shall be
               made so that the holders of the Series Preferred shall be
               entitled to receive upon conversion thereof, in addition to the
               number of shares of Common Stock receivable thereupon, the amount
               of other securities of the Company which they would have received
               had their Series Preferred been converted into Common Stock on
               the date of such event and had they thereafter, during the period
               from the date of such event to and including the conversion date,
               retained such securities receivable by them as aforesaid during
               such period, subject to all other adjustments called for during
               such period under this Section 4 with respect to the rights of
               the holders of the Series Preferred or with respect to such other
               securities by their terms.

                    h. Adjustment for Reclassification and Recapitalization. If
               at any time or from time to time after the Original Issue Date,
               the Common Stock issuable upon the conversion of the Series
               Preferred is changed into the same or a different number of
               shares of any class or classes of stock, whether by
               recapitalization, reclassification or otherwise (other than an
               Acquisition or Asset Transfer as defined in Section 3d or a
               subdivision or combination of Common Stock or other dividend or
               distribution or a reorganization, merger, consolidation or sale
               of assets provided for elsewhere in this Section 4), in any such
               event, provision shall be made so that the holders of the Series
               Preferred shall thereafter be entitled to receive upon conversion
               of the Series Preferred the number of shares of stock or other
               securities or other property of the Company to which a holder of
               the number of shares of Common Stock deliverable upon conversion
               would have been entitled on such recapitalization,
               reclassification or change, all subject to further adjustment as
               provided herein or with respect to such other securities or
               property by the terms thereof.

                    i. Reorganizations, Mergers, Consolidations or Sales of
               Assets. If at any time or from time to time after the Original
               Issue Date, there is a capital reorganization of the Common Stock
               (other than an Acquisition or Asset Transfer as defined in
               Section 3d or a subdivision or combination of Common Stock or
               other dividend or distribution, capitalization, subdivision,
               combination or reclassification of shares provided for elsewhere
               in this Section 4), as a part of such capital reorganization,
               provision shall be made so that the holders of the Series
               Preferred shall thereafter be entitled to receive upon conversion
               of the Series Preferred the number of shares of stock or other
               securities or property of the Company to which a holder of the
               number of shares of Common Stock deliverable upon conversion
               would have been entitled on such capital reorganization, subject
               to adjustment in respect of such stock or securities by the terms
               thereof. In any such case, appropriate adjustment shall be made
               in the application of the provisions of this Section 4 with
               respect to the rights of the holders of Series Preferred after
               the capital reorganization to the end that the provisions of this
               Section 4 (including adjustment of the Series Preferred
               Conversion Price then in effect and the number of shares issuable
               upon conversion of the Series Preferred) shall be applicable
               after that event and be as nearly equivalent as practicable.

                    j. Sale of Shares Below Series Preferred Conversion Price.

                         (i) If at any time or from time to time after the
                    Original Issue Date, the Company issues or sells, or is
                    deemed by the express provisions of this subsection 4j to
                    have issued or sold, Additional Shares of Common Stock (as
                    defined in subsection 4j(iv) below), other than as a
                    dividend or other distribution on any class of stock as
                    provided in Section 4f above, and other than a subdivision
                    or combination of shares of Common Stock as provided in
                    Section 4e above, for an Effective Price (as defined in
                    subsection 4j(iv) below) less than the then effective Series
                    Preferred Conversion Price, then and in each such case the
                    then existing Series Preferred Conversion Price shall be
                    reduced, as of the opening of business on the date of such
                    issue or sale, to a price determined by multiplying the
                    Series Preferred Conversion Price by a fraction (i) the
                    numerator of which shall be (A) the number of shares of
                    Common Stock deemed outstanding (as defined below)
                    immediately prior to such issue or sale, plus (B) the number
                    of shares of Common Stock which the aggregate consideration
                    received (as defined in subsection 4j(ii)) by the Company
                    for the total number of Additional Shares of Common Stock so
                    issued would purchase at such Series Preferred Conversion
                    Price, and (ii) the denominator of which shall be the number
                    of shares of Common Stock deemed outstanding (as defined
                    below) immediately prior to such issue or sale plus the
                    total number of Additional Shares of Common Stock so issued.
                    For the purposes of the preceding sentence, the number of
                    shares of Common Stock deemed to be outstanding as of a
                    given date shall be the sum of (A) the number of shares of
                    Common Stock actually outstanding, (B) the number of shares
                    of Common Stock into which the then outstanding shares of
                    Series Preferred could be converted if fully converted on
                    the day immediately preceding the given date, and (C) the
                    number of shares of Common Stock which could be obtained
                    through the exercise or conversion of all other rights,
                    options and convertible securities, including options
                    granted pursuant to the Company's employee stock option
                    plan, exercisable on the day immediately preceding the given
                    date, which either were outstanding on the Original Issue
                    Date or the issuance of which was approved by a majority of
                    the Company's Board of Directors, which majority includes at
                    least one director appointed by the Series Preferred.

                         (ii) For the purpose of making any adjustment required
                    under this Section 4j, the consideration received by the
                    Company for any issue or sale of securities shall (A) to the
                    extent it consists of cash, be computed at the net amount of
                    cash received by the Company after deduction of any
                    underwriting or similar commissions, compensation or
                    concessions paid or allowed by the Company in connection
                    with such issue or sale but without deduction of any
                    expenses payable by the Company, (B) to the extent it
                    consists of property other than cash, be computed at the
                    fair value of that property as determined in good faith by
                    the Board of Directors, and (C) if Additional Shares of
                    Common Stock, Convertible Securities (as defined in
                    subsection 4j(iii)) or rights or options to purchase either
                    Additional Shares of Common Stock or Convertible Securities
                    are issued or sold together with other stock or securities
                    or other assets of the Company for a consideration which
                    covers both, be computed as the portion of the consideration
                    so received that may be reasonably determined in good faith
                    by the Board of Directors to be allocable to such Additional
                    Shares of Common Stock, Convertible Securities or rights or
                    options.

                        (iii) For the purpose of the adjustment required under
                    this Section 4j, if the Company issues or sells (A) stock or
                    other securities convertible into Additional Shares of
                    Common Stock (such convertible stock or securities being
                    herein referred to as "Convertible Securities") or (B)
                    rights or options for the purchase of Additional Shares of
                    Common Stock or Convertible Securities and if the Effective
                    Price of such Additional Shares of Common Stock is less than
                    the Series Preferred Conversion Price, in each case the
                    Company shall be deemed to have issued at the time of the
                    issuance of such rights or options or Convertible Securities
                    the maximum number of Additional Shares of Common Stock
                    issuable upon exercise or conversion thereof and to have
                    received as consideration for the issuance of such shares an
                    amount equal to the total amount of the consideration, if
                    any, received by the Company for the issuance of such rights
                    or options or Convertible Securities, plus, in the case of
                    such rights or options, the minimum amounts of
                    consideration, if any, payable to the Company upon the
                    exercise of such rights or options, plus, in the case of
                    Convertible Securities, the minimum amounts of
                    consideration, if any, payable to the Company (other than by
                    cancellation of liabilities or obligations evidenced by such
                    Convertible Securities, except to the extent of the excess,
                    if any, of the amount or value of the cash, securities or
                    property that will be payable by the Company upon the
                    maturity, redemption or other event triggering a payment
                    obligation of the Company with respect to any such
                    Convertible Securities, assuming none of them are converted,
                    over the sum of the amount or value of the consideration
                    received or deemed to be received by the Company for such
                    Convertible Securities calculated as set forth in this
                    sentence plus the amount or value of the cash, securities or
                    other property, except shares of Common Stock, if any, that
                    would be payable by the Company with respect to such
                    Convertible Securities if it were assumed that all of them
                    are fully converted) upon the conversion thereof; provided
                    that (x) if in the case of Convertible Securities the
                    minimum amounts of such consideration cannot be ascertained,
                    but are a function of antidilution or similar protective
                    clauses, the Company shall be deemed to have received the
                    minimum amounts of consideration without reference to such
                    clauses; (y) if the minimum amount of consideration payable
                    to the Company upon the exercise or conversion of rights,
                    options or Convertible Securities is reduced over time or on
                    the occurrence or non-occurrence of specified events other
                    than by reason of antidilution adjustments, the Effective
                    Price shall be recalculated using the figure to which such
                    minimum amount of consideration is reduced; and (z) if the
                    minimum amount of consideration payable to the Company upon
                    the exercise or conversion of such rights, options or
                    Convertible Securities is subsequently increased, the
                    Effective Price shall be again recalculated using the
                    increased minimum amount of consideration payable to the
                    Company upon the exercise or conversion of such rights,
                    options or Convertible Securities. No further adjustment of
                    the Series Preferred Conversion Price, as adjusted upon the
                    issuance of such rights, options or Convertible Securities,
                    shall be made as a result of the actual issuance of
                    Additional Shares of Common Stock on the exercise of any
                    such rights or options or the conversion of any such
                    Convertible Securities. If any such rights or options or the
                    conversion privilege represented by any such Convertible
                    Securities shall expire without having been exercised, the
                    Series Preferred Conversion Price as adjusted upon the
                    issuance of such rights, options or Convertible Securities
                    shall be readjusted to the Series Preferred Conversion Price
                    which would have been in effect had an adjustment been made
                    on the basis that the only Additional Shares of Common Stock
                    so issued were the Additional Shares of Common Stock, if
                    any, actually issued or sold on the exercise of such rights
                    or options or rights of conversion of such Convertible
                    Securities, and such Additional Shares of

                    Common Stock, if any, were issued or sold for the
                    consideration actually received by the Company upon such
                    exercise, plus the consideration, if any, actually received
                    by the Company for the granting of all such rights or
                    options, whether or not exercised, plus the consideration
                    received for issuing or selling the Convertible Securities
                    actually converted, plus the consideration, if any, actually
                    received by the Company (other than by cancellation of
                    liabilities or obligations evidenced by such Convertible
                    Securities, except to the extent of the excess, if any, of
                    the amount or value of the cash, securities or property
                    that, but for such conversion, would have been payable by
                    the Company upon the maturity, redemption or other event
                    triggering a payment obligation of the Company with respect
                    to any such Convertible Securities over the sum of the
                    amount or value of the consideration received or deemed to
                    be received by the Company for such Convertible Securities
                    calculated as set forth in this sentence plus the amount or
                    value of the cash, securities or other property, except
                    shares of Common Stock, if any, actually paid by the Company
                    with respect to the Convertible Securities actually
                    converted) on the conversion of such Convertible Securities,
                    provided that such readjustment shall not apply to prior
                    conversions of Series Preferred.

                         (iv) "Additional Shares of Common Stock" shall mean all
                    shares of Common Stock issued by the Company or deemed to be
                    issued pursuant to this Section 4j, whether or not
                    subsequently reacquired or retired by the Company other than
                    (A) shares of Common Stock issued upon conversion of the
                    Series Preferred, (B) shares of Common Stock and/or options,
                    warrants or other Common Stock purchase rights, and the
                    Common Stock issued pursuant to such options, warrants or
                    other rights (as adjusted for any stock dividends,
                    combinations, splits, recapitalizations and the like)
                    before, on or after the Original Issue Date to employees,
                    officers or directors of, or consultants or advisors to the
                    Company or any subsidiary pursuant to stock purchase or
                    stock option plans or other arrangements that are approved
                    by the Board and (C) shares of Common Stock issued pursuant
                    to the exercise of options, warrants or convertible
                    securities outstanding as of the Original Issue Date. The
                    "Effective Price" of Additional Shares of Common Stock shall
                    mean the quotient determined by dividing the total number of
                    Additional Shares of Common Stock issued or sold, or deemed
                    to have been issued or sold by the Company under this
                    Section 4j, into the aggregate consideration received, or
                    deemed to have been received by the Company for such issue
                    under this Section 4j, for such Additional Shares of Common
                    Stock.

                    k. Certificate of Adjustment. In each case of an adjustment
               or readjustment of the Series Preferred Conversion Price for the
               number of shares of Common Stock or other securities issuable
               upon conversion of the Series Preferred, if the Series Preferred
               is then convertible pursuant to this Section 4, the Company, at
               its expense, shall compute such adjustment or readjustment in
               accordance with the provisions hereof and prepare a certificate
               showing such adjustment or readjustment, and shall mail such
               certificate, by first class mail, postage prepaid, to each
               registered holder of Series Preferred at the holder's address as
               shown in the Company's books. The certificate shall set forth
               such adjustment or readjustment, showing in detail the facts upon
               which such adjustment or readjustment is based, including a
               statement of (i) the consideration received or deemed to be
               received by the Company for any Additional Shares of

                                       11
<PAGE>

               Common Stock issued or sold or deemed to have been issued or
               sold, (ii) the Series Preferred Conversion Price at the time in
               effect, (iii) the number of Additional Shares of Common Stock and
               (iv) the type and amount, if any, of other property which at the
               time would be received upon conversion of the Series Preferred.

                    l. No Further Adjustments. Each adjustment pursuant to any
               provision of this Section 4 by reason of any event or
               circumstance shall be made without duplication and not under more
               than one subsection this Section 4. Notwithstanding any other
               provision of this Section 4, no adjustment shall be made or
               required (whether under subsection 4i or otherwise) by reason of
               any Acquisition or Asset Transfer that is or is deemed to be a
               liquidation under Section 3d above, by reason of any other
               liquidation, distribution or winding up of the Company or by
               reason of any payment or distribution to the holders of, or any
               change in, the Company's Common Stock or other capital stock. Any
               adjustment of the Series Preferred Conversion Price that would
               otherwise be required with respect to any share of Series
               Preferred Stock may be postponed (except in the case of a
               subdivision or combination of shares of the Common Stock) up to,
               but not beyond the date of conversion of such share, if such
               adjustment either by itself or with other adjustments not
               previously made adjusts the applicable Series Preferred
               Conversion price by less than $.01.

                    m. Notices of Record Date. Upon (i) any taking by the
               Company of a record of the holders of any class of securities for
               the purpose of determining the holders thereof who are entitled
               to receive any dividend or other distribution, or (ii) any
               Acquisition (as defined in Section 3d) or other capital
               reorganization of the Company, any reclassification or
               recapitalization of the capital stock of the Company, any merger
               or consolidation of the Company with or into any other
               corporation, or any Asset Transfer (as defined in Section 3c), or
               any voluntary or involuntary dissolution, liquidation or winding
               up of the Company, the Company shall mail to each holder of
               Series Preferred at least twenty (20) days prior to the record
               date specified therein a notice specifying (A) the date on which
               any such record is to be taken for the purpose of such dividend
               or distribution and a description of such dividend or
               distribution, (B) the date on which any such Acquisition,
               reorganization, reclassification, transfer, consolidation,
               merger, Asset Transfer, dissolution, liquidation or winding up is
               expected to become effective, and (C) the date, if any, that is
               to be fixed as to when the holders of record of Common Stock (or
               other securities) shall be entitled to exchange their shares of
               Common Stock (or other securities) for securities or other
               property deliverable upon such Acquisition, reorganization,
               reclassification, transfer, consolidation, merger, Asset
               Transfer, dissolution, liquidation or winding up.

                    n. Automatic Conversion.

                         (i) Each share of Series Preferred shall automatically
                    be converted into shares of Common Stock, based on the
                    then-effective Series Preferred Conversion Price, (A) at any
                    time upon the affirmative election of the holders of at
                    least a majority of the outstanding shares of the Series
                    Preferred, or (B) immediately upon the closing of a firmly
                    underwritten public offering pursuant to an effective
                    registration statement under the Securities Act of 1933, as
                    amended, covering the offer and sale of Common Stock for the
                    account of the Company in which (i) the per share price is
                    at least four (4) times the Original Issue Price (as
                    adjusted for stock splits, dividends, recapitalizations and
                    the like), and (ii) the gross cash

                                       12
<PAGE>

                    proceeds to the Company (before underwriting discounts,
                    commissions and fees) are at least Fifteen Million Dollars
                    $15,000,000. Upon such automatic conversion, any declared
                    and unpaid dividends shall be paid in accordance with the
                    provisions of Section 4d.

                         (ii) Upon the occurrence of the event specified in
                    paragraph (A) above, the outstanding shares of Series
                    Preferred shall be converted automatically without any
                    further action by the holders of such shares and whether or
                    not the certificates representing such shares are
                    surrendered to the Company or its transfer agent; provided,
                    however, that the Company shall not be obligated to issue
                    certificates evidencing the shares of Common Stock issuable
                    upon such conversion unless the certificates evidencing such
                    shares of Series Preferred are either delivered to the
                    Company or its transfer agent as provided below, or the
                    holder notifies the Company or its transfer agent that such
                    certificates have been lost, stolen or destroyed and
                    executes an agreement satisfactory to the Company to
                    indemnify the Company from any loss incurred by it in
                    connection with such certificates. Upon the occurrence of
                    such automatic conversion of the Series Preferred, the
                    holders of Series Preferred shall surrender the certificates
                    representing such shares at the office of the Company or any
                    transfer agent for the Series Preferred. Thereupon, there
                    shall be issued and delivered to such holder promptly at
                    such office and in its name as shown on such surrendered
                    certificate or certificates, a certificate or certificates
                    for the number of shares of Common Stock into which the
                    shares of Series Preferred surrendered were convertible on
                    the date on which such automatic conversion occurred, and
                    any declared and unpaid dividends shall be paid in
                    accordance with the provisions of Section 4d.

                    o. Fractional Shares. No fractional shares of Common Stock
               shall be issued upon conversion of Series Preferred. All shares
               of Common Stock (including fractions thereof) issuable upon
               conversion of more than one share of Series Preferred by a holder
               thereof shall be aggregated for purposes of determining whether
               the conversion would result in the issuance of any fractional
               share. If, after the aforementioned aggregation, the conversion
               would result in the issuance of any fractional share, the Company
               shall, in lieu of issuing any fractional share, pay cash equal to
               the product of such fraction multiplied by the Common Stock's
               fair market value (as determined by the Board of Directors) on
               the date of conversion.

                    p. Reservation of Stock Issuable Upon Conversion. The
               Company shall at all times reserve and keep available out of its
               authorized but unissued shares of Common Stock, solely for the
               purpose of effecting the conversion of the shares of the Series
               Preferred, such number of its shares of Common Stock as shall
               from time to time be sufficient to effect the conversion of all
               outstanding shares of the Series Preferred. If at any time the
               number of authorized but unissued shares of Common Stock shall
               not be sufficient to effect the conversion of all then
               outstanding shares of the Series Preferred, the Company will take
               such corporate action as may, in the opinion of its counsel, be
               necessary to increase its authorized but unissued shares of
               Common Stock to such number of shares as shall be sufficient for
               such purpose.

                    q. Notices. Any notice required by the provisions of this
               Section 4 shall be in writing and shall be deemed effectively
               given: (i) upon personal delivery to the party to be notified,
               (ii) when sent by confirmed telex or facsimile if sent during
               normal business hours of the recipient; if not, then on the next
               business day, (iii) five (5) days after having been sent by

                                       13

<PAGE>

               registered or certified mail, return receipt requested, postage
               prepaid, or (iv) one (1) day after deposit with a nationally
               recognized overnight courier, specifying next day delivery, with
               written verification of receipt. All notices shall be addressed
               to each holder of record at the address of such holder appearing
               on the books of the Company.

                    r. Payment of Taxes. The Company will pay all United States
               taxes (other than taxes based upon income) and other United
               States governmental charges that may be imposed with respect to
               the issue or delivery of shares of Common Stock upon conversion
               of shares of Series Preferred, excluding any tax or other charge
               imposed in connection with any transfer involved in the issue and
               delivery of shares of Common Stock in a name other than that in
               which the shares of Series Preferred so converted were
               registered.

                    s. No Dilution or Impairment. Without the consent of the
               holders of then outstanding Series Preferred as required under
               Section 2b, the Company shall not amend its Restated Certificate
               of Incorporation or participate in any reorganization, transfer
               of assets, consolidation, merger, dissolution, issue or sale of
               securities or take any other voluntary action, for the purpose of
               avoiding or seeking to avoid the observance or performance of any
               of the terms to be observed or performed hereunder by the
               Company, but shall at all times in good faith assist in carrying
               out all such action as may be reasonably necessary or appropriate
               in order to protect the conversion rights of the holders of the
               Series Preferred against dilution or other impairment.

                    t. Listing Requirements. To the extent that delivery to any
               holder or any shares of Series Preferred of Common Stock or other
               securities or property upon the conversion of such shares
               requires, under any applicable law or rule of the Nasdaq Stock
               Market or any national securities exchange or interdealer
               quotation system, requires any registration, qualification,
               listing or approval before such Common Stock or other securities
               or property may be lawfully or properly issued, such holder shall
               cooperate in good faith with the Company in satisfying such
               requirement, and the conversion of such shares and the delivery
               of such Common Stock, securities or other property shall be
               postponed until such requirements is satisfied, whereupon such
               conversion shall be consummated (as of the date specified in
               Section 4d above) and such delivery shall be made as promptly as
               reasonably practicable. Unless otherwise set forth in any
               agreement relating to registration of such shares of Common Stock
               or other written agreement between or binding on such holder and
               the Company, each of the Company and such holder shall bear its
               own costs and expenses in connection with the foregoing.

          5. REDEMPTION. The Series Preferred shall not be redeemable.

          6. NO REISSUANCE OF SERIES PREFERRED. No share or shares of Series
     Preferred acquired by the Corporation by reason of redemption, purchase,
     conversion or otherwise shall be reissued.

     F. NO PREEMPTIVE RIGHTS. Stockholders shall have no preemptive rights
except as granted by the Company pursuant to written agreements.

     A. To the extent permitted by applicable law a director of the corporation
shall not be personally liable to the Corporation or its stockholders for
monetary damages for any breach of fiduciary duty as a director, except for
liability (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) under
Section 174 of the Delaware General Corporation Law, or (iv) for any transaction
from which the director derived an improper personal benefit. To the extent
permitted by applicable law if the Delaware General Corporation Law is amended

further eliminating or limiting the personal liability of directors, then the
liability of a director shall be eliminated or limited to the fullest extent
permitted by the Delaware General Corporation Law, as so amended.

     B. Any repeal or modification of this Article V shall only be prospective
and shall not effect the rights under this Article V in effect at the time of
the alleged occurrence of any action or omission to act giving rise to
liability.

                                       VI.

Corporation shall be vested in its Board of Directors. The number of directors
which shall constitute the whole Board of Directors shall be fixed by the Board
of Directors in the manner provided in the Bylaws.

     B. The Board of Directors may from time to time make, amend, supplement or
repeal the Bylaws; provided, however, that the stockholders may change or repeal
any Bylaw adopted by the Board of Directors by the affirmative vote of the
percentage of holders of capital stock as provided therein; and, provided
further, that no amendment or supplement to the Bylaws adopted by the Board of
Directors shall vary or conflict with any amendment or supplement thus adopted
by the stockholders.

     C. The directors of the Corporation need not be elected by written ballot
unless the Bylaws so provide.

stockholders present at a meeting shall not have authority to adjourn the
meeting. Notice need not be given of any such adjourned meeting if the date,

that meeting unless a new record date is or must be set for the adjourned
meeting. A new record date must be set if the meeting is adjourned in a single

meeting, notice of the adjourned meeting shall be given to each stockholder of
record entitled to vote at the adjourned meeting consistent with the new record

by vote of a majority of the then authorized number of directors, except that
the number of directors may not be decreased to less than two unless all the
shares of the Corporation are owned beneficially and of record by less than two
stockholders. When used in these By-Laws, the phrase "entire Board" means the
total number of directors which the Corporation would have if there were no
vacancies.

     Section 3.03. Election and Term. The Board shall be divided into three
classes: Class I, Class II and Class III. Each class shall consist, as nearly as

Class I directors shall expire at the annual meeting of stockholders in 2001;
the term of office of the initial Class II directors shall expire at the annual
meeting of stockholders in 2002; and the term of office of the initial Class III
directors shall expire at the annual meeting of stockholders in 2003. At each
annual meeting of stockholders of the Corporation, the successors of that class
of directors whose term expires at that meeting shall be elected to hold office
for a term

outstanding capital stock of the Corporation entitled to vote thereon, voting
together as a single class. Except as may otherwise be provided by law,
"cause" for removal, for purposes of this Section, shall exist only if: (i)
the director whose removal is proposed has been convicted of a felony, or has
been granted immunity to testify in an action where another has been convicted
of a felony, by a court of competent jurisdiction and such conviction is no
longer subject to direct appeal; (ii) such director has become mentally
incompetent, whether or not so adjudicated, which mental incompetence directly
affects his ability as a director of the Corporation, as determined by at least
66-2/3% of the members of the Board then in office (other than such director);
or (iii) such director's actions or failure to act have been determined by at
least 66-2/3% of the  members of the Board then in office (other than such
director) to be in  derogation of the director's duties.

     Section 3.05. Resignations. Any director may resign at any time by giving

take effect at the time specified therein or, if the time when it shall become

remaining director. Any director elected in accordance with the preceding
sentence shall hold office for the remainder of the full term of the class of
directors in which the vacancy occurred or to which the new directorship is
apportioned, and until such director's successor shall have been elected and
qualified. No decrease in the number of directors constituting the Board shall
shorten the term of any incumbent director, except as may be provided in the
terms of any class or series of preferred stock with respect to any additional
director elected by the holders of such class or series of preferred stock.

     Section 3.07. Chairman of the Board. The directors shall elect one of their

                                ---------------

          (a) The Corporation shall indemnify to the fullest extent now or
     hereafter provided for or permitted by law each person involved in, or made
     or threatened to be made a party to, any action, suit, claim or proceeding,
     arbitration, alternative dispute resolution mechanism, investigation,
     administrative or legislative hearing or any other actual, threatened,
     pending or completed proceeding, whether civil or criminal, or whether
     formal or informal, and including an action by or in the right of the
     Corporation or any other corporation, or any partnership, joint venture,
     trust, employee benefit plan or other enterprise, whether profit or
     non-profit (any such entity, other than the Corporation, being hereinafter
     referred to as an "Enterprise"), and including appeals therein (any such
     process being hereinafter referred to as a "Proceeding"), by reason of the
     fact that such person, such person's testator or intestate (i) is or was a
     director or officer of the Corporation, or (ii) while serving as a director
     or officer of the Corporation, is or was serving, at the request of the
     Corporation, as a director, officer, or in any other capacity, any other
     Enterprise, against any and all judgments, fines, penalties, amounts paid

     reasonably incurred as a result of or in connection with any Proceeding, or
     any appeal therein, except as provided in Section 7.01(b) of this Article
     VII.

          (b) No indemnification shall be made to or on behalf of any such
     person if a judgment or other final adjudication adverse to such person
     establishes that such person's acts were committed in bad faith or were the
     result of active and deliberate dishonesty and were material to

                                      -29-

     the cause of action so adjudicated, or that such person personally gained
     in fact a financial profit or other advantage to which such person was not
     legally entitled. In addition, no indemnification shall be made with
     respect to any Proceeding initiated by any such person against the
     Corporation, or a director or officer of the Corporation, other than to
     enforce the terms of this Article VII, unless such Proceeding was
     authorized by the Board. Further, no indemnification shall be made with
     respect to any settlement or compromise of any Proceeding unless and until
     the Corporation has consented to such settlement or compromise.

      Section 7.02. Insurance. The Corporation may maintain insurance, at its
expense, to protect itself and any director, officer, employee or agent of the
Corporation or another corporation against any expense, liability or loss,
whether or not the Corporation would have the power to indemnify such person
against such expense, liability or loss under the General Corporation Law of the
State of Delaware.

                             LINKSHARE CORPORATION

                        WARRANT TO PURCHASE COMMON STOCK


Issue date: _______________, 2000

1.  General.  THIS CERTIFIES THAT, _________ (the "Holder") is entitled to
    -------
subscribe for and purchase up to ______ shares of fully paid and nonassessable
common stock of LinkShare Corporation, a Delaware corporation (the "Company"),
at a price of $1.00 per share (the "Exercise Price") subject to the provisions
and upon the terms and conditions hereinafter set forth.  This warrant (this
"Warrant") is being issued to the Holder in connection with a promissory note
issued by the Company to the Holder on February 7, 2000.

2.  Exercise Period.  This Warrant may be exercised by the Holder at any time
    ---------------
and from time to time beginning the issue date above for a term of five (5)
years.

3.  Method of Exercise; Payment
    ---------------------------

a.  Cash Exercise.  The Holder may exercise this Warrant in whole or in part, by
    -------------
surrendering this Warrant (with the notice of exercise form attached hereto as
Exhibit A duly executed) at the principal office of the Company and by the
- ---------
payment to the Company, by certified, cashier's or other check acceptable to the
Company, of an amount equal to the aggregate purchase price of the shares of
common stock being purchased.

b.  Net Issue Exercise.  In lieu of exercising this Warrant with cash, the
    ------------------
Holder may elect to receive shares equal to the value of this Warrant (or the
portion thereof being canceled) by surrendering this Warrant at the principal
office of the Company together with notice of such election, in which event the
Company shall issue to the Holder a number of shares of common stock computed
using the following formula:
<PAGE>

                                  X = Y (A-B)
                                      -------
                                         A

     where:

            X  =  the number of share of common stock to be issued to the
                  Holder;

            Y  =  the number of share of common stock purchasable under this
                  Warrant or, if only a portion of this Warrant is being
                  exercised, the portion of this Warrant being canceled (at the
                  date of such calculation);

            A  =  the Fair Market Value (as defined below) of a share of common
                  (at the date of such calculation); and

            B  =  the Exercise Price (on the date of such calculation).

c.  Fair Market Value.  The "Fair Market Value" of a share of common stock shall
    -----------------
be as follows:

i.  if the Company's common stock is traded on an exchange or is quoted on the
Nasdaq National Market, the closing price of the business day immediately
preceding the exercise date; or

ii.  otherwise, as determined in good faith by the Company's board of directors.

d.  Stock Certificates.  In the event the Holder exercises any of the rights
    ------------------
represented by this Warrant to purchase the Company's common stock, the Company
shall deliver to the Holder certificates representing such shares within a
reasonable time and, unless the Holder has fully exercised this Warrant or the
Warrant has expired, a new warrant representing the remaining shares underlying
this Warrant.

4.  Reservation of Shares.  The Company covenants and agrees that all shares of
    ---------------------
common stock which may be issued upon the exercise of this Warrant will, upon
issuance, be duly authorized, validly issued, fully paid and nonassessable, free
from all preemptive rights of any shareholder and free from all taxes, liens and
charges created by the Company with respect to the issue thereof.  During the
period within which the Holder may exercise this Warrant, the Company will at
all times have authorized, and reserved for the purpose of issuance upon
exercise of this Warrant, a sufficient number of shares of common stock to
provide for the exercise of the rights represented by this Warrant.

5.  Adjustment of Exercise Price and Number of Shares.  The number and kind of
    -------------------------------------------------
securities purchasable upon the exercise of this Warrant and the Exercise Price
shall be subject to adjustment
<PAGE>

from time to time upon the occurrence of certain events as follows:

a.  Reclassification or Merger.  In case of any reclassification, change or
    --------------------------
conversion of securities of the class issuable upon exercise of this Warrant
(other than a change in par value or as a result of a subdivision or
combination), or in case of any merger of the Company with or into another
company (other than (i) a merger effected solely for the purpose of changing the
Company's jurisdiction of incorporation or (ii) a merger with another company in
which the Company is the acquiring and surviving corporation and which does not
result in any reclassification or change of outstanding securities issuable upon
exercise of this Warrant), or in case of any sale of all or substantially all of
the assets of the Company, the Company, or such successor or purchasing company,
as the case may be, shall duly execute and deliver to the Holder a new warrant,
so that the Holder shall have the right to receive, at a total purchase price
not to exceed that payable upon the exercise of the unexercised portion of this
Warrant, and in lieu of the common stock theretofore issuable upon exercise of
this Warrant, the kind and amount of shares of stock, other securities, money
and property receivable upon such reclassification, change or merger by a holder
of the number of shares of common stock under this Warrant.  Such new warrant
shall provide for adjustments as nearly equivalent as may be practicable to the
adjustments provided for in this section.  The provisions of this subparagraph
(a) shall similarly apply to successive reclassifications, changes, mergers,
consolidations and transfers.

b.  Combination or Subdivision of Shares.  If the Company at any time while this
    ------------------------------------
Warrant remains outstanding and unexpired shall combine its outstanding shares
of common stock, the number of shares purchasable shall be proportionally
decreased and the Exercise Price proportionally increased effective concurrently
with such combination.  In the case of a subdivision, the number of shares
purchasable shall be proportionally increased and the Exercise Price
proportionally decreased effective concurrently with such subdivision.

c.  Stock Dividends.  If the Company at any time while this Warrant is
    ---------------
outstanding and unexpired shall pay a dividend with respect to common stock in
common stock, then the Exercise Price shall be adjusted, from and after the date
of determination of shareholders entitled to receive such dividend or
distribution, to that price determined by multiplying the Exercise Price in
effect immediately prior to such date of determination by a fraction (i) the
numerator of which shall be the total number of shares of common stock
outstanding immediately prior to such dividend or distribution and (ii) the
denominator of which shall be the total number of shares of common stock
outstanding immediately after such dividend or distribution.

6.  Fractional Shares.  No fractional shares will be issued in connection with
    -----------------
any exercise hereunder, but in lieu of such fractional shares the Company shall
make a cash payment therefor upon the basis of the Exercise Price then in
effect.

7.  Compliance with Securities Law.  The Holder, by acceptance hereof, agrees
    ------------------------------
that the Holder is acquiring this Warrant, and the shares of common stock to be
issued upon exercise hereof, for investment and will not offer, sell or
otherwise dispose of this Warrant, or any shares of common stock to be issued
upon exercise hereof, except under circumstances which will not result in a
<PAGE>

violation of the Securities Act of 1933 (the "Securities Act").  Upon exercise
of this Warrant, unless the shares being acquired are registered under the
Securities Act or an exemption from such registration is available, the holder
hereof shall confirm in writing, by executing the form attached as Schedule 1 to
                                                                   ----------
Exhibit A hereto, that the common stock so acquired are being acquired for
- ---------
investment and not with a view towards distribution or resale.  This Warrant and
all shares of common stock issued upon exercise of this Warrant shall be stamped
or imprinted with a legend in substantially the following form:

     "THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, OR UNDER ANY STATE SECURITIES LAWS.  THEY
MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN
EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER SAID ACT OR AN
OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION IS NOT
REQUIRED."

8.  Transferability.  Subject to compliance with applicable federal and state
    ---------------
securities laws, this Warrant and all rights hereunder are transferable, in
whole or in part, without charge to the Holder hereof (except for transfer
taxes), upon surrender of this Warrant properly endorsed.

9.  Rights as Shareholders.  No Holder, solely as such, shall be entitled to
    ----------------------
vote or receive dividends or be deemed a shareholder of the Company.

10.  Modification and Waiver.  This Warrant and any provision hereof may be
     -----------------------
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

11.  Notices of Change.
     -----------------

a.  Promptly upon any adjustment in the number or class of shares subject to
this Warrant and of the Exercise Price, the Company shall give written notice
thereof to the Holder, setting forth in reasonable detail and certifying the
calculation of such adjustment.

b.  The Company shall give written notice to the Holder at least ten (10)
business days prior to the date on which the Company closes its books or takes a
record for determining rights to receive any dividends or distributions.

12.  Transfer Books.  The Company will at no time close its transfer books
     --------------
against the transfer of this Warrant or of any shares of common stock issued or
issuable upon the exercise of this Warrant in any manner which interferes with
the timely exercise of this Warrant.

13.  Loss, Theft, Destruction, or Mutilation.  The Company represents and
     ---------------------------------------
warrants to the Holder that, upon receipt of evidence reasonably satisfactory to
the Company of the loss, theft, destruction, or mutilation of this Warrant and,
in the case of any such loss, theft or destruction, upon receipt of an indemnity
reasonably satisfactory to the Company, or in the case of any such mutilation
<PAGE>

upon surrender and cancellation of this Warrant, the Company, at the Holder's
expense, will make and deliver a new warrant of like tenor in lieu of the lost,
stolen, destroyed or mutilated Warrant.

14.  Notices.  Any notice, request, communication or other document required or
     -------
permitted to be given or delivered to the Holder or the Company shall be
delivered via overnight courier by certified or registered mail, postage
prepaid, to the Holder's address as shown on the books of the Company or to the
Company at the address indicated on the signature page of this Warrant.

15.  Binding Effect on Successors.  Except as otherwise set forth herein, this
     ----------------------------
Warrant shall be binding upon any company succeeding the Company by merger,
consolidation or acquisition of all or substantially all of the Company's
assets.

16.  Descriptive Headings.  The descriptive headings of the several paragraphs
     --------------------
of this Warrant are inserted for convenience only and do not constitute a part
of this Warrant.

17.  Governing Law.  This Warrant shall be construed and enforced in accordance
     -------------
with, and the rights of the parties shall be governed by, the laws of the State
of New York.

       In connection with the purchase of the above-listed shares of common
stock (the "Securities"), the undersigned (the "Purchaser") represents to
LinkShare Corporation  (the "Company") as follows:

       (a) The Purchaser is aware of the Company's business affairs and
financial condition, and has acquired sufficient information about the Company
to reach an informed and knowledgeable decision to acquire the Securities.  The
Purchaser is purchasing the Securities for its own account for investment
purposes only and not with a view to, or for the resale in connection with, any
"distribution" thereof for purposes of the Securities Act of 1933, as amended
(the "Securities Act").

       (b) The Purchaser understands that the Securities have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of the Purchaser's investment intent as expressed herein.  In this
connection, the Purchaser understands that, in the view of the Securities and
Exchange Commission (the "SEC"), the statutory basis for such exemption may be
unavailable if the Purchaser's representation was predicated solely upon a
present intention to hold these Securities for the minimum capital gains period
specified under tax statutes, for a deferred sale, for or until an increase or
decrease in the market price of the Securities, or for a period of one year or
any other fixed period in the future.

       (c) The Purchaser further understands that the Securities must be held
indefinitely unless subsequently registered under the Securities Act or unless
an exemption from registration is otherwise available.  Moreover, the Purchaser
understands that the Company is under no obligation to register the Securities.
In addition, the Purchaser understands that the certificate evidencing the
Securities will be imprinted with the legend referred to in the Warrant under
which the Securities are being purchased.

       (d) The Purchaser is aware of the provisions of Rule 144, promulgated
under the Securities Act, which, in substance, permit limited public resale of
"restricted securities" acquired, directly or indirectly, from the issuer
thereof (or from an affiliate of such issuer), in a non-public offering subject
to the satisfaction of certain conditions, if
<PAGE>

applicable, including, among other things: The availability of certain public
information about the Company, the resale occurring not less than one year after
the party has purchased and paid for the securities to be sold; the sale being
made through a broker in an unsolicited "broker's transaction" or in
transactions directly with a market maker (as said term is defined under the
Securities Exchange Act of 1934, as amended) and the amount of securities being
sold during any three-month period not exceeding the specified limitations
stated therein.

       (e) The Purchaser further understands that at the time it wishes to sell
the Securities there may be no public market upon which to make such a sale, and
that, even if such a public market then exists, the Company may not be
satisfying the current public information requirements of Rule 144 and that, in
such event, the Purchaser may be precluded from selling the Securities under
Rule 144 even if the one-year minimum holding period had been satisfied.

       (f) The Purchaser further understands that in the event all of the
requirements of Rule 144 are not satisfied, registration under the Securities
Act, compliance with Regulation A, or some other registration exemption will be
required, and that, notwithstanding the fact that Rule 144 is not exclusive, the
SEC has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rule 144 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk.

LinkShare Corporation
215 Park Avenue, 8th Floor
New York, New York 10003

Dear Sirs and Madames:

         As counsel for LinkShare Corporation, a Delaware corporation (the
"Company"), we have examined and are familiar with the registration statement on
Form S-1, File No. 333-_______ (the "Registration Statement"), which relates to
the registration under the Securities Act of 1933, as amended, of _________
shares (the "Shares") of the Company's Common Stock, par value $.001 per share,
to be issued and sold to the underwriters (the "Underwriters") named in the
Registration Statement under the heading "Underwriting."

         In connection therewith, we have examined, among other things,
originals, certified copies or copies otherwise identified to our satisfaction
as being copies of originals, of the Certificate of Incorporation, as amended,
and Bylaws of the Company, in the forms filed as Exhibits 3.1 and 3.3,
respectively, to the Registration Statement; the proposed Restated Certificate
of Incorporation (the "Restated Charter") and By-Laws of the Company, in the
forms filed as Exhibits 3.2 and 3.4, respectively, to the Registration
Statement; records of proceedings of the Company's Board of Directors, including
committees thereof, with respect to the filing of the Registration Statement and
related matters; the form of Underwriting Agreement, in the form filed as
Exhibit 1.1 to the Registration Statement (the "Underwriting Agreement"); and
such other documents, records, certificates of public officials and questions of
law as we deemed necessary or appropriate for the purpose of this opinion. In
rendering this opinion, we have relied, to the extent we deem such reliance
appropriate, on certificates of officers of the Company as to factual matters.
We have assumed the authenticity of all documents submitted to us as originals
and the conformity to authentic original documents of all documents submitted to
us as certified, conformed or reproduction copies. We have further assumed that
there will be no changes in applicable law between the date of this opinion and
the date of issuance and sale of the Shares to the Underwriters.

         Based upon the foregoing, we are of the opinion that when (i) the
Restated Charter is accepted for filing by the Secretary of State of the State
of Delaware, and (ii) the Shares are issued, signed by the transfer agent and
delivered pursuant to the Underwriting Agreement and paid for by the
Underwriters in accordance therewith, such Shares will be duly authorized,
validly issued, fully paid and non-assessable.

Registration Statement and to the reference to us contained therein under the
heading "Legal Matters." In giving the foregoing consent, we do not admit that
we are in the category of persons whose consent is required under Section 7 of
the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission promulgated thereunder.

SECTION 2.  REGISTRATION; RESTRICTIONS ON TRANSFER

                  (a) In addition to the restrictions contained in the First
         Refusal and Co-Sale Agreement, each Holder agrees not to make any
         disposition of all or any portion of the Shares or Registrable
         Securities unless and until:

                           (i) There is then in effect a registration statement
                  under the Securities Act covering such proposed disposition
                  and such disposition is made in accordance with such
                  registration statement; or

                           (ii) (A) The transferee has agreed in writing to be

                  have notified the Company of the proposed disposition and
                  shall have furnished the Company with a detailed statement of

                  the Company, that such disposition will not require
                  registration of such shares under the Securities Act; provided
                  that subclause (ii)(A) shall not apply to a transferee who
                  acquires Registrable Securities in a transaction exempt from
                  registration under Rule 144 under the Securities Act.

                  (b) Each certificate representing Shares or Registrable
         Securities shall (unless otherwise permitted by the provisions of the
         Agreement) be stamped or otherwise imprinted with a legend

         required under applicable laws or contract):

                                        3
<PAGE>

                  THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                  UNDER THE SECURITIES ACT OF 1933 AS AMENDED (THE "ACT") AND
                  MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED,
                  PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE
                  ACT OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL
                  SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH
                  REGISTRATION IS NOT REQUIRED.

                  (c) The Company shall be obligated to reissue promptly
         certificates not bearing the foregoing legend at the request of any
         Holder thereof to the extent that the securities evidenced thereby that
         are proposed to be disposed of by such Holder have been registered for
         such disposition or the Holder shall have obtained an opinion of
         counsel (which counsel may be counsel to the Company) reasonably
         acceptable to the Company to the effect that the securities proposed to
         be disposed of may lawfully be so disposed of without registration
         under the Act or legend.

                  (d) Any legend endorsed on an instrument pursuant to
         applicable state securities laws and the stop-transfer instructions
         with respect to such securities shall be removed upon receipt by the
         Company of an order of the appropriate blue sky authority authorizing
         such removal.

         2.2 Demand Registration.

                  (a) Subject to the conditions of this Section 2.2, if the
         Company shall receive a written request from either (i) the Investors
         holding a majority of the outstanding Registrable Securities held by
         all Investors (the "Initiating") or (ii) the Founders holding a
         majority of the outstanding Registrable Securities held by all
         Founders, that the Company file a registration statement under the
         Securities Act covering the registration of at least a majority of the
         Registrable Securities then outstanding (or a lesser percent if the
         anticipated aggregate offering price, net of underwriting discounts and
         commissions, would be equal to or greater than $1,000,000 (a "Qualified
         Public Offering")), then the Company shall, within thirty (30) days of
         the receipt thereof, give written notice of such request to all
         Holders, and subject to the limitations of this Section 2.2, use its
         best efforts to effect, as soon as practicable, the registration under
         the Securities Act of all Registrable Securities that the Holders
         request to be registered.

                  (b) If the Initiating Investors or the Initiating Founders,
         respectively intend to distribute the Registrable Securities covered by
         their request by means of an underwriting, they shall so advise the
         Company as a part of their request made pursuant to this Section 2.2 or
         any request pursuant to Section 2.4 and the Company shall include such
         information in the written notice referred to in Section 2.2(a) or
         Section 2.4(a), as applicable. In such event, the right of any Holder
         to include its Registrable Securities in such registration shall be
         conditioned upon such Holder's participation in such underwriting and
         the inclusion of such Holder's Registrable Securities in the
         underwriting to the extent provided herein. All Holders proposing to
         distribute their securities

                                        4
<PAGE>

         through such underwriting shall enter into an underwriting agreement in
         customary form with the underwriter or underwriters selected for such
         underwriting by the Company (which underwriter or underwriters shall be
         reasonably acceptable to a majority in interest of the Initiating
         Holders). Notwithstanding any other provision of this Section 2.2 or
         Section 2.4, if the underwriter advises the Company that marketing
         factors require a limitation of the number of securities to be
         underwritten (including Registrable Securities) then the Company shall
         so advise all Holders of Registrable Securities which would otherwise
         be underwritten pursuant hereto, and the number of shares that may be
         included in the underwriting shall be allocated to the Holders of such
         Registrable Securities on a pro rata basis based on the number of
         Registrable Securities held by all such Holders (including the
         Initiating Holders). Any Registrable Securities excluded or withdrawn
         from such underwriting shall be withdrawn from the registration.

                  (c) The Company shall not be required to effect a registration
         pursuant to this Section 2.2:

                           (i) prior to the earlier of (A) the second
                  anniversary of the date of this Agreement or (B) one hundred
                  eighty (180) days following the effective date of the
                  registration statement pertaining to the Initial Offering;

                           (ii) for the Initiating Investors after the Company
                  has effected two (2) registrations pursuant to this Section
                  2.2, and for the Initiating Founders after the Company has
                  effected two (2) registrations pursuant to this Section 2.2,
                  and such registrations have been declared or ordered
                  effective;

                           (iii) either (A) during the period starting with the
                  date of filing of, and ending on the date one hundred eighty
                  (180) days following the effective date of the registration
                  statement pertaining to the Initial Offering or (B) during the
                  period starting with the date of filing of, and ending on the
                  date ninety (90) days following the effective date of a
                  registration statement other than the Initial Offering in
                  which such Initiating Investors or Initiating Founders had the
                  right to participate pursuant to Section 2.3, including a
                  registration statement in which the underwriters reduced the
                  Holders' participation pursuant to Section 2.3(a); provided
                  that the Company makes reasonable good faith efforts to cause
                  such registration statement to become effective;

                           (iv) if within thirty (30) days of receipt of a
                  written request from Initiating Holders pursuant to Section
                  2.2(a), the Company gives notice to the Holders of the
                  Company's intention to make an offering described in (A) or
                  (B) of clause (iii) within ninety (90) days;

                           (v) if the Company shall furnish to Holders
                  requesting a registration statement pursuant to this Section
                  2.2, a certificate signed by the Chairman of the Board stating
                  that in the good faith judgment of the Board of Directors of
                  the Company, it would be seriously detrimental to the Company
                  and its shareholders for such registration statement to be
                  effected at such time, in which event the Company shall have
                  the right to defer such filing for a period of not more than
                  ninety (90) days after receipt of the request of the
                  Initiating Holders; provided that such right

                                        5
<PAGE>

                  to delay a request shall be exercised by the Company not more
                  than once in any twelve (12) month period; or

                           (vi) if the Initiating Holders propose to dispose of
                  shares of Registrable Securities that may be immediately
                  registered on Form S-3 pursuant to a request made pursuant to
                  Section 2.4 below or such shares may be sold without volume
                  limitations under Rule 144 under the Securities Act.

         2.3 Piggyback Registrations. The Company shall notify all Holders of
Registrable Securities in writing at least thirty (30) days prior to the filing
of any registration statement under the Securities Act for purposes of a public
offering of securities of the Company (including, but not limited to,
registration statements relating to secondary offerings of securities of the
Company, but excluding registration statements relating to employee benefit
plans or with respect to corporate reorganizations or other transactions under
Rule 145 of the Securities Act) and will afford each such Holder an opportunity
to include in such registration statement all or part of such Registrable
Securities held by such Holder. Each Holder desiring to include in any such
registration statement all or any part of the Registrable Securities held by it
shall, within fifteen (15) days after the above-described notice from the
Company, so notify the Company in writing. Such notice shall state the intended
method of disposition of the Registrable Securities by such Holder. If a Holder
decides not to include all of its Registrable Securities in any registration
statement thereafter filed by the Company, such Holder shall nevertheless
continue to have the right to include any Registrable Securities in any
subsequent registration statement or registration statements as may be filed by
the Company with respect to offerings of its securities, all upon the terms and
conditions set forth herein.

                  (a) Underwriting. If the registration statement under which
         the Company gives notice under this Section 2.3 is for an underwritten
         offering, the Company shall so advise the Holders of Registrable
         Securities. In such event, the right of any such Holder to be included
         in a registration pursuant to this Section 2.3 shall be conditioned
         upon such Holder's participation in such underwriting and the inclusion
         of such Holder's Registrable Securities in the underwriting to the
         extent provided herein. All Holders proposing to distribute their
         Registrable Securities through such underwriting shall enter into an
         underwriting agreement in customary form with the underwriter or
         underwriters selected for such underwriting by the Company.
         Notwithstanding any other provision of the Agreement, if the
         underwriter determines in good faith that marketing factors require a
         limitation of the number of shares to be underwritten, the number of
         shares that may be included in the underwriting shall be allocated,
         first, to the Company; second, to the Holders who have elected to
         participate in such underwriting on a pro rata basis based on the
         respective total numbers of Registrable Securities held by such
         Holders; and third, to any other shareholder of the Company based on
         the respective total number of shares of Common Stock held by such
         other stockholders on a pro rata basis. No such reduction shall reduce
         the securities being offered by the Company for its own account to be
         included in the registration and underwriting. In no event will shares
         of any other selling shareholder be included in such registration which
         would reduce the number of shares which may be included by Holders
         without the written consent of Holders of not less than sixty-six and
         two-thirds percent (66- 2/3%) of the Registrable Securities proposed to
         be sold in the offering. If any Holder disapproves of the terms of any
         such underwriting, such Holder may elect to withdraw

                                        6
<PAGE>

         therefrom by written notice to the Company and the underwriter,
         delivered at least ten (10) business days prior to the effective date
         of the registration statement. Any Registrable Securities excluded or
         withdrawn from such underwriting shall be excluded and withdrawn from
         the registration.

                  (b) Right to Terminate Registration. The Company shall have
         the right to terminate or withdraw any registration initiated by it
         under this Section 2.3 prior to the effectiveness of such registration
         whether or not any Holder has elected to include securities in such
         registration. The Registration Expenses of such withdrawn registration
         shall be borne by the Company in accordance with Section 2.5 hereof.

         2.4 Form S-3 Registration. In case the Company shall receive from any
one or more Investors or Founders holding Registrable Securities a written
request or requests that the Company effect a registration on Form S-3 (or any
successor to Form S-3) or any similar shortform registration statement and any
related qualification or compliance with applicable State Securities laws, if
any, with respect to all or a part of the Registrable Securities owned by such
Holder or Holders, the Company will:

                  (a) promptly give written notice of the proposed registration,
         and any related qualification or compliance, to all other Holders of
         Registrable Securities; and

                  (b) as soon as reasonably practicable, effect such
         registration and all such qualifications and compliances as may be so
         requested and as would permit or facilitate the sale and distribution
         of all or such portion of such Holder's or Holders' Registrable
         Securities as are specified in such request, together with all or such
         portion of the Registrable Securities of any other Holder or Holders
         joining in such request as are specified in a written request given
         within fifteen (15) days after receipt of such written notice from the
         Company; provided, however, that the Company shall not be obligated to
         effect any such registration, qualification or compliance pursuant to
         this Section 2.4:

                           (i) if Form S-3 (or any successor or similar form) is
                  not available for such offering by the Holders, or

                           (ii) if the Holders, entitled to inclusion in such
                  registration propose to sell Registrable Securities and such
                  other securities (if any) at an aggregate price to the public
                  of less than three million dollars ($3,000,000), or

                           (iii) if the Company shall furnish to the Holders a
                  certificate signed by the Chairman of the Board of Directors
                  of the Company stating that in the good faith judgment of the
                  Board of Directors of the Company, it would be seriously
                  detrimental to the Company and its shareholders for such Form
                  S-3 registration to be effected at such time, in which event
                  the Company shall have the right to defer the filing of the
                  Form S-3 registration statement for a period of not more than
                  ninety (90) days after receipt of the request of the Holder or
                  Holders under this Section 2.4; provided, that such right to
                  delay a request shall be exercised by the Company not more
                  than once in any twelve (12) month period, or

                                        7
<PAGE>

                           (iv) if the Company has, within the twelve (12) month
                  period preceding the date of such request, already effected
                  one (1) registration on Form S-3 for any of the Holders
                  pursuant to this Section 2.4, or

                           (v) in any particular jurisdiction in which the
                  Company would be required to qualify to do business, to
                  execute a general consent to service of process or become
                  subject to taxation in effecting such registration,
                  qualification or compliance.

                  (c) Subject to the foregoing, the Company shall file a Form
         S-3 registration statement covering the Registrable Securities and
         other securities so requested to be registered as soon as reasonably
         practicable after receipt of the request or requests of the Holders.
         Registrations effected pursuant to this Section 2.4 shall not be
         counted as demands for registration or registrations effected pursuant
         to Sections 2.2 or 2.3, respectively.

         2.5 Expenses of Registration. Except as specifically provided herein,
all Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to Section 2.2 or any registration under
Section 2.3 or Section 2.4 herein shall be borne by the Company. All Selling
Expenses incurred in connection with any registrations hereunder, shall be borne
by the holders of the securities so registered pro rata on the basis of the
number of shares so registered. The Company shall not, however, be required to
pay for any Registration Expenses of any registration proceeding begun pursuant
to Section 2.2 or 2.4, the request of which has been subsequently withdrawn by
the Holders participating therein unless (a) the withdrawal is based upon
material adverse information concerning the Company of which the Holders
initiating such registration were not aware at the time of such request or (b)
if the Initiating Holders were any Investors or Founders, one or more Investors
holding a majority of Registrable Securities held by the Investors or one or
more Founders holding a majority of the Registrable Securities held by the
Founders, respectively, agree to forfeit their right to one requested
registration pursuant to Section 2.2 or Section 2.4, as applicable (in which
event such right shall be forfeited by all Investors or Founders, respectively).
If the Holders participating therein are required to pay the Registration
Expenses, such expenses shall be borne by the Holders participating therein in
proportion to the number of shares for which registration was requested. If the
Company is required to pay the Registration Expenses of a withdrawn offering
pursuant to clause (a) above, then the Holders shall not forfeit their rights
pursuant to Section 2.2 or Section 2.4 to a demand registration.

         2.6 Obligations of the Company. Whenever required to effect the
registration of any Registrable Securities, the Company shall, as expeditiously
as reasonably possible:

                  (a) Prepare and file with the SEC a registration statement
         with respect to such Registrable Securities and use all reasonable
         efforts to cause such registration statement to become effective, and,
         upon the request of the Holders of a majority of the Registrable
         Securities registered thereunder, keep such registration statement
         effective for up to ninety (90) days or, if earlier, until the Holder
         or Holders have completed the distribution related thereto. The Company
         shall not be required to file, cause to become effective or maintain
         the effectiveness of any registration statement

                                        8
<PAGE>

         that contemplates a distribution of securities on a delayed or
         continuous basis pursuant to Rule 415 under the Securities Act.

                  (b) Prepare and file with the SEC such amendments and
         supplements to such registration statement and the prospectus used in
         connection with such registration statement as may be necessary to
         comply with the provisions of the Securities Act with respect to the
         disposition of all securities covered by such registration statement
         for the period set forth in paragraph (a) above.

                  (c) Furnish to the Holders such number of copies of a
         prospectus, including a preliminary prospectus, in conformity with the
         requirements of the Securities Act, and such other documents as they
         may reasonably request in order to facilitate the disposition of
         Registrable Securities owned by them.

                  (d) Use its reasonable best efforts to register and qualify
         the securities covered by such registration statement under such other
         securities or Blue Sky laws of such jurisdictions as shall be
         reasonably requested by the Holders; provided that the Company shall
         not be required in connection therewith or as a condition thereto to
         qualify to do business or to file a general consent to service of
         process in any such states or jurisdictions.

                  (e) In the event of any underwritten public offering, enter
         into and perform its obligations under an underwriting agreement, in
         usual and customary form, with the managing underwriter(s) of such
         offering. Each Holder participating in such underwriting shall also
         enter into and perform its obligations under such an agreement.

                  (f) Notify each Holder of Registrable Securities covered by
         such registration statement at any time when a prospectus relating
         thereto is required to be delivered under the Securities Act of the
         happening of any event as a result of which the prospectus included in
         such registration statement, as then in effect, includes an untrue
         statement of a material fact or omits to state a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading in the light of the circumstances then existing.

                  (g) Use its best efforts to furnish, on the date that such
         Registrable Securities are delivered to the underwriters for sale, if
         such securities are being sold through underwriters, (i) an opinion,
         dated as of such date, of the counsel representing the Company for the
         purposes of such registration, in form and substance as is customarily
         given to underwriters in an underwritten public offering, addressed to
         the underwriters, if any, and (ii) a letter dated as of such date, from
         the independent certified public accountants of the Company, in form
         and substance as is customarily given by independent certified public
         accountants to underwriters in an underwritten public offering
         addressed to the underwriters.

         2.7 Termination of Registration Rights. All registration rights granted
under this Section 2 shall terminate and be of no further force and effect five
(5) years after the date of the Company's Initial Offering. In addition, a
Holder's registration rights shall expire if (a) the

                                        9
<PAGE>

Company has completed its Initial Offering and is subject to the provisions of
Section 13 or 15(d) of the Exchange Act, (b) such Holder (together with its
affiliates, partners and former partners) holds less than 1% of the Company's
outstanding Common Stock (treating all share of convertible Preferred Stock on
an as converted basis) and (c) all Registrable Securities held by and issuable
to such Holder (and its affiliates, partners, former partners, members and
former members) may be sold under Rule 144 without any volume limitations.

         2.8 Delay of Registration; Furnishing Information.

                  (a) No Holder shall have any right to obtain or seek an
         injunction restraining or otherwise delaying any such registration as
         the result of any controversy that might arise with respect to the
         interpretation or implementation of this Section 2.

                  (b) It shall be a condition precedent to the obligations of
         the Company to take any action pursuant to Section 2.2, 2.3 or 2.4 that
         the selling Holders shall furnish to the Company such information
         regarding themselves, the Registrable Securities held by them and the
         intended method of disposition of such securities as shall be required
         to effect the registration of their Registrable Securities.

                  (c) The Company shall have no obligation with respect to any
         registration requested pursuant to Section 2.2 or Section 2.4 if, due
         to the operation of Subsection 2.2 (b) or due to the withdrawal of such
         request by one or more Holders, the number of shares or the anticipated
         aggregate offering price of the Registrable Securities to be included
         in the registration does not equal or exceed the number of shares or
         the anticipated aggregate offering price required to originally trigger
         the Company's obligation to initiate such registration as specified in
         Section 2.2 or Section 2.4, whichever is applicable, but no event due
         to the operation of Section 2.2 (b) shall result in the loss of any of
         the demand registrations allowed under Section 2.2 (a).

         2.9 Indemnification. In the event any Registrable Securities are
included in a registration statement under Sections 2.2, 2.3 or 2.4:

                  (a) To the extent permitted by law, the Company will indemnify
         and hold harmless each Holder, the partners, officers and directors of
         each Holder, any underwriter (as defined in the Securities Act) for
         such Holder and each person, if any, who controls such Holder or
         underwriter within the meaning of the Securities Act or the Exchange
         Act, against any losses, claims, damages, or liabilities (joint or
         several) to which they may become subject under the Securities Act, the
         Exchange Act or other federal or state law, insofar as such losses,
         claims, damages or liabilities (or actions in respect thereof) arise
         out of or are based upon any of the following statements, omissions or
         violations (collectively a "Violation") by the Company: (i) any untrue
         statement or alleged untrue statement of a material fact contained in
         such registration statement, including any preliminary prospectus or
         final prospectus contained therein or any amendments or supplements
         thereto, (ii) 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 (iii) any violation or alleged

                                       10
<PAGE>

         violation by the Company of the Securities Act, the Exchange Act, any
         state securities law or any rule or regulation promulgated under the
         Securities Act, the Exchange Act or any state securities law in
         connection with the offering covered by such registration statement;
         and the Company will pay as incurred to each such Holder, partner,
         officer, director, underwriter or controlling person for any legal or
         other expenses reasonably incurred by them in connection with
         investigating or defending any such loss, claim, damage, liability or
         action; provided however, that the indemnity agreement contained in
         this Section 2.9(a) shall not apply to amounts paid in settlement of
         any such loss, claim, damage, liability or action if such settlement is
         effected without the consent of the Company, which consent shall not be
         unreasonably withheld, nor shall the Company be liable in any such case
         for any such loss, claim, damage, liability or action to the extent
         that it arises out of or is based upon a Violation which occurs in
         reliance upon and in conformity with written information furnished
         expressly for use in connection with such registration by such Holder,
         partner, officer, director, underwriter or controlling person of such
         Holder.

                  (b) To the extent permitted by law, each Holder will, if
         Registrable Securities held by such Holder are included in the
         securities as to which such registration qualifications or compliance
         is being effected, indemnify and hold harmless the Company, each of its
         directors, its officers, any underwriter (as defined in the Securities
         Act) for the Company and each person, if any, who controls the Company
         or underwriter within the meaning of the Securities Act, and any other
         Holder selling securities under such registration statement or any of
         such other Holder's partners, directors or officers or any person who
         controls such Holder, against any losses, claims, damages or
         liabilities (joint or several) to which they may become subject under
         the Securities Act, the Exchange Act or other federal or state law,
         insofar as such losses, claims, damages or liabilities (or actions in
         respect thereto) arise out of or are based upon any Violation, in each
         case to the extent (and only to the extent) that such Violation occurs
         in reliance upon and in conformity with written information furnished
         expressly for use in connection with such registration by such Holder,
         partner, officer, director, underwriter or controlling person of such
         Holder and each such Holder will pay as incurred any legal or other
         expenses reasonably incurred by the Company or any such director,
         officer, controlling person, underwriter or other Holder, or partner,
         officer, director or controlling person of such other Holder in
         connection with investigating or defending any such loss, claim,
         damage, liability or action if it is judicially determined that there
         was such a Violation; provided, however, that the indemnity agreement
         contained in this Section 2.9(b) shall not apply to amounts paid in
         settlement of any such loss, claim, damage, liability or action if such
         settlement is effected without the consent of the Holder, which consent
         shall not be unreasonably withheld; provided further, that in no event
         shall any indemnity under this Section 2.9 exceed the proceeds from the
         offering received by such Holder.

                  (c) Promptly after receipt by an indemnified party under this
         Section 2.9 of notice of the commencement of any action (including any
         governmental action), such indemnified party will, if a claim in
         respect thereof is to be made against any indemnifying party under this
         Section 2.9, deliver to the indemnifying party a written notice of the
         commencement thereof and the indemnifying party shall have the right to
         participate in, and, to the extent the indemnifying party so desires,
         jointly with any other indemnifying party similarly noticed, to assume
         the defense thereof

                                       11
<PAGE>

         with counsel mutually satisfactory to the parties; provided, however,
         that an indemnified party shall have the right to retain its own
         counsel, with the fees and expenses to be paid by the indemnifying
         party, if representation of such indemnified party by the counsel
         retained by the indemnifying party would be inappropriate due to actual
         or potential differing interests between such indemnified party and any
         other party represented by such counsel in such proceeding. The failure
         to deliver written notice to the indemnifying party within a reasonable
         time of the commencement of any such action, if materially prejudicial
         to its ability to defend such action, shall relieve such indemnifying
         party of any liability to the indemnified party under this Section 2.9,
         but the omission so to deliver written notice to the indemnifying party
         will not relieve it of any liability that it may have to any
         indemnified party otherwise than under this Section 2.9.

                  (d) If the indemnification provided for in this Section 2.9 is
         held by a court of competent jurisdiction to be unavailable to an
         indemnified party with respect to any losses, claims, damages or
         liabilities referred to herein, the indemnifying party, in lieu of
         indemnifying such indemnified party thereunder, shall to the extent
         permitted by applicable law contribute to the amount paid or payable by
         such indemnified party as a result of such loss, claim, damage or
         liability in such proportion as is appropriate to reflect the relative
         fault of the indemnifying party on the one hand and of the indemnified
         party on the other in connection with the Violation(s) that resulted in
         such loss, claim, damage or liability, as well as any other relevant
         equitable considerations. The relative fault of the indemnifying party
         and of the indemnified party shall be determined by a court of law by
         reference to, among other things, whether the untrue or alleged untrue
         statement of a material fact or the omission to state a material fact
         relates to information supplied by the indemnifying party or by the
         indemnified party and the parties' relative intent, knowledge, access
         to information and opportunity to correct or prevent such statement or
         omission; provided, that in no event shall any contribution by a Holder
         hereunder exceed the proceeds from the offering received by such
         Holder.

                  (e) The obligations of the Company and Holders under this
         Section 2.9 shall survive completion of any offering of Registrable
         Securities in a registration statement and the termination of this
         agreement. No indemnifying party, in the defense of any such claim or
         litigation, shall, except with the consent of each indemnified party,
         consent to entry of any judgment or enter into any settlement which
         does not include as an unconditional term thereof the giving by the
         claimant or plaintiff to such indemnified party of a release from all
         liability in respect to such claim or litigation.

                  (f) Notwithstanding the foregoing, to the extent that the
         provisions on indemnification and contribution contained in the
         underwriting agreement entered into in connection with any public
         offering in which any Holders are participating are in conflict with
         the foregoing provisions, the provisions in the underwriting agreement
         shall control.

         2.10 Assignment of Registration Rights. The rights to cause the Company
to register Registrable Securities pursuant to this Section 2 may be assigned to
by a Holder to a transferee or assignee of Registrable Securities, pursuant to a
prior contractual obligation and with no additional

                                       12
<PAGE>

consideration paid in the case of clauses (b) and (f) below, which (a) is a
subsidiary or parent, (b) is a general partner, limited partner, retired
partner, member or retired member of a Holder, (c) is a Holder's family member
or trust for the benefit of an individual Holder or such Holder's family members
or custodian for the benefit of a Holder's children, (d) is already a party to
this Agreement, (e) is the estate or legal representative of such Holder upon
such Holder's death or adjudication of incompetency (f) is a stockholder,
officer or director of the Company, or (g) acquires at least two hundred fifty
thousand (250,000) shares of Registrable Securities (as adjusted for stock
splits and combinations); provided, however, (i) the transferor shall, within
ten (10) days after such transfer, furnish to the Company written notice of the
name and address of such transferee or assignee and the securities with respect
to which such registration rights are being assigned and (ii) such transferee
shall agree to be subject to all restrictions set forth in this Agreement; and
provided further that, in the case of any transferee specified in this Section
2.10, that (i) such transferee is not a competitor and (ii) the transfer of
Registrable Securities to such transferee is permitted by and made in accordance
with the applicable provisions of the First Refusal and Co-Sale Agreement.

         2.11 Amendment of Registration Rights. Any provision of this Section 2
may be amended and the observance thereof may be waived (either generally or in
a particular instance and either retroactively or prospectively), only with the
written consent of the Company and the Holders of at least sixty-six and
two-thirds percent (66-2/3%) of the Registrable Securities then outstanding. Any
amendment or waiver effected in accordance with this Section 2.11 shall be
binding upon each Holder and the Company. By acceptance of any benefits under
this Section 2, Holders of Registrable Securities hereby agree to be bound by
the provisions hereunder.

         2.12 Limitation on Subsequent Registration Rights. After the date of
this Agreement, the Company shall not, without the prior written consent of the
Holders of sixty-six and two-thirds percent (66-2/3%) of the Registrable
Securities then outstanding, enter into any agreement with any holder or
prospective holder of any securities of the Company that would grant such holder
registration rights pari passu or senior to those granted to the Holders
hereunder.

         2.13 "Market Stand-Off" Agreement; Agreement to Furnish Information.
Each Holder hereby agrees that such Holder shall not sell or otherwise transfer
or dispose of any Common Stock (or other securities) of the Company held by such
Holder (other than those included in the registration) for a period specified by
the representative of the underwriters of Common Stock (or other securities) of
the Company not to exceed one hundred eighty (180) days following the effective
date of a registration statement of the Company filed under the Securities Act
for a public offering of the Company's securities; provided that all officers
and directors of the Company and holders of at least ten percent (10%) of the
Company's voting securities enter into similar agreements.

         Each Holder agrees to execute and deliver such other agreements as may
be reasonably requested by the Company or the underwriter which are consistent
with the foregoing or which are necessary to give further effect thereto. In
addition, if requested by the Company or the representative of the underwriters
of Common Stock (or other securities) of the Company, each Holder shall provide,
within fifteen (15) days of such request, such information as may be required

                                       13
<PAGE>

by the Company or such representative in connection with the completion of any
public offering of the Company's securities pursuant to a registration statement
filed under the Securities Act. The obligations described in this Section 2.13
shall not apply to a registration relating solely to employee benefit plans on
Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or
a registration relating solely to a Commission Rule 145 transaction on Form S-4
or similar forms that may be promulgated in the future. The Company may impose
stop-transfer instructions with respect to the shares of Common Stock (or other
securities) subject to the foregoing restriction until the end of said one
hundred eighty (180) day period.

         2.14 Rule 144 Reporting. With a view to making available to the Holders
the benefits of certain rules and regulations of the SEC which may permit the
sale of the Registrable Securities to the public without registration, the
Company agrees to use its best efforts to:

                  (a) Make and keep public information available, as those terms
         are understood and defined in SEC Rule 144 or any similar or analogous
         rule promulgated under the Securities Act, at all times after the
         effective date of Initial Offering and while the Company continues to
         be subject to the reporting requirements of Section 15(d) or Section 13
         of the Exchange Act;

                  (b) File with the SEC, in a timely manner, all reports and
         other documents required of the Company under the Exchange Act; and

                  (c) So long as a Holder owns any Registrable Securities,
         furnish to such Holder forthwith upon request: a written statement by
         the Company as to its compliance with the reporting requirements of
         said Rule 144 of the Securities Act, and of the Exchange Act (at any
         time after it has become subject to such reporting requirements); a
         copy of the most recent annual or quarterly report of the Company filed
         with the SEC; and such other publicly available reports and documents
         as a Holder may reasonably request in availing itself of any rule or
         regulation of the SEC allowing it to sell any such securities without
         registration.

SECTION 3.  COVENANTS OF THE COMPANY

         3.1 Basic Financial Information and Reporting.

                  (a) The Company will maintain true books and records of
         account in which full and correct entries will be made of all its
         business transactions pursuant to a system of accounting established
         and administered in accordance with generally accepted accounting
         principles consistently applied, and will set aside on its books all
         such proper accruals and reserves as shall be required under generally
         accepted accounting principles consistently applied.

                  (b) As soon as practicable after the end of each fiscal year
         of the Company, and in any event within ninety (90) days thereafter,
         the Company will furnish each Holder a balance sheet of the Company, as
         at the end of such fiscal year, and a statement of income and a
         statement of cash flows of the Company, for such year, all prepared in
         accordance with generally accepted

                                       14
<PAGE>

         accounting principles consistently applied and setting forth in each
         case in comparative form the figures for the previous fiscal year, all
         in reasonable detail. Such financial statements shall be accompanied by
         a report and opinion thereon by independent public accountants of
         national standing selected by the Company's Board of Directors.

                  (c) So long as any Holder (with its affiliates) shall own not
         less than two hundred fifty thousand (250,000) shares of Registrable
         Securities (as adjusted for stock splits and combinations) (a "Major
         Holder"), the Company will furnish each such Major Holder, as soon as
         practicable after the end of the first, second and third quarterly
         accounting periods in each fiscal year of the Company, and in any event
         within forty-five (45) days thereafter, a balance sheet of the Company
         as of the end of each such quarterly period, and a statement of income
         and a statement of cash flows of the Company for such period and for
         the current fiscal year to date, prepared in accordance with generally
         accepted accounting principles, with the exception that no notes need
         be attached to such statements and year-end audit adjustments may not
         have been made.

                  (d) The Company will furnish each such Major Holder (i) at
         least thirty (30) days prior to the beginning of each fiscal year an
         annual budget and operating plans for such fiscal year (and as soon as
         available, any subsequent revisions thereto); and (ii) as soon as
         practicable after the end of each month, and in any event within twenty
         (20) days thereafter, a balance sheet of the Company as of the end of
         each such month, and a statement of income and a statement of cash
         flows of the Company for such month and for the current fiscal year to
         date, including a comparison to plan figures for such period, prepared
         in accordance with generally accepted accounting principles
         consistently applied, with the exception that no notes need be attached
         to such statements and year-end audit adjustments may not have been
         made.

         3.2 Inspection Rights. Each such Major Holder shall have the right to
visit and inspect any of the properties of the Company or any of its
subsidiaries, and to discuss the affairs, finances and accounts of the Company
or any of its subsidiaries with its officers, and to review such information as
is reasonably requested all at such reasonable times and as often as may be
reasonably requested; provided, however, that the Company shall not be obligated
under this Section 3.2 with respect to a competitor of the Company or with
respect to information which the Board of Directors determines in good faith is
confidential and should not, therefore, be disclosed.

         3.3 Confidentiality of Records.

                  (a) Each Holder agrees to use, and to use its best efforts to
         insure that its authorized representatives use, the same degree of care
         as such Holder uses to protect its own confidential information to keep
         confidential any information furnished to it which the Company
         identifies as being confidential or proprietary (so long as such
         information is not in the public domain), except that such Holder may
         disclose such proprietary or confidential information to any partner,
         subsidiary, parent or agent of such Holder for the purpose of
         evaluating its investment in the Company as long as such partner,
         subsidiary, parent or agent is advised of the confidentiality

                                       15
<PAGE>

         provisions of this Section 3.3 and any Confidentiality Agreement
         between the Company and such Holder.

                  (b) Notwithstanding any provision of this Section 3 or any
         other provision of this Agreement actually or apparently to the
         contrary, the Company shall not be required to, and shall not provide
         any Investor with any non-public information or any access or
         inspection rights under Section 3.2 or otherwise if the Company
         reasonably believes that such Investor (or any of its affiliates) is a
         competitor (unless such Investor furnishes the Company with reasonable
         evidence that it and its affiliates are not competitors) or unless such
         Investor executes and delivers or previously has executed and delivered
         to the Company a confidentiality agreement in substantially the form of
         the Initial Investor Confidentiality Agreement. The provisions of this
         Section 3.3 are supplemental to and do not supersede, terminate or
         amend the terms of the Initial Investor Confidentiality Agreement or
         any other confidentiality agreement which any Investor may enter into
         with the Company.

                  (c) The Investors hereby acknowledge and agree that (i) by
         reason of such Investor being furnished or granted access to material
         non-public information regarding the Company as provided herein, such
         Investor may be prohibited from purchasing or selling securities of the
         Company unless and until such information is disclosed to the public
         generally or to the persons with whom such Investor effects such
         purchases or sales, (ii) the Company has and will have no obligation to
         make such disclosure and (iii) such Investor is and will be prohibited
         by the confidentiality provisions of this Agreement and any separate
         confidentiality agreement which such Investor has or shall enter into
         with the Company from making such disclosure.

         3.4 Reservation of Common Stock. The Company will at all times reserve
and keep available, solely for issuance and delivery upon the conversion of the
Preferred Stock, all Common Stock issuable from time to time upon such
conversion.

         3.5 Stock Vesting. Unless otherwise determined by a majority of the
Board of Directors, which majority shall include at least one of the Directors
designated or elected by the Investors and at least one of the Directors
designated or elected by the Founders, all stock options and other stock
equivalents issued after the date of this Agreement to employees, directors,
consultants and other service providers shall be subject to vesting as follows:
(a) twenty-five percent (25%) of such stock shall vest at the end of the first
year following the earlier of the date of issuance or such person's services
commencement date with the Company, and (b) seventy-five percent (75%) of such
stock shall vest over the remaining three (3) years. With respect to any shares
of stock purchased by any such person, the Company's repurchase option shall
provide that upon such person's termination of employment or service with the
Company, with or without cause, the Company or its assignee (to the extent
permissible under applicable securities laws and other laws) shall have the
option to purchase at cost any unvested shares of stock held by such person.

         3.6 Key Man Insurance. Unless otherwise determined by a majority of the
Board of Directors, which majority shall include at least one of the Directors
designated or elected by the

                                       16
<PAGE>

Investors and at least one of Directors designated or elected by the Founders,
the Board of Directors, the Company will use its best efforts to obtain and
maintain in full force and effect term life insurance in the amount of one
million ($1,000,000) dollars on the lives of each of Stephen Messer, Heidi
Messer and Jianhao Meng naming the Company as beneficiary.

         3.7 Proprietary Information and Inventions Agreement. Unless otherwise
determined by a majority of the Board of Directors, which majority shall include
at least one of the Directors designated or elected by the Investors and at
least one of Directors designated or elected by the Founders, the Company shall
require all employees and consultants to execute and deliver a Proprietary
Information and Inventions Agreement in the form attached to the Purchase
Agreement.

         3.8 Approval. The Company shall not without the approval of a majority
of the Board of Directors, which majority shall include at least one of the
Directors designated by the Investors and at least one of the Directors

         pursuant to their employment agreements with the Company).

                  (vii) decisions to enter into, amend, terminate, or exercise,

merger or other reorganization in which the holders of the Company's outstanding
voting stock immediately prior to such transaction own, immediately after such
transaction, securities representing less than fifty percent (50%) of the voting
power of the corporation or other entity surviving such transaction (a "Change
in Control"). In addition, Sections 3.1(c), Section 3.1(d) and Section 3.2 shall
no longer apply to a Holder who is no longer a Major Holder.

SECTION 4.  RIGHTS OF FIRST REFUSAL

         4.1 Subsequent Offerings. Each Major Investor and Founder (each a
"Right Holder") shall have a right of first refusal to purchase its pro rata
share of all Equity Securities, as defined below, that the Company may, from
time to time, propose to sell and issue after the date of this Agreement, other
than the Equity Securities excluded by Section 4.7 hereof. Each Right Holder's
pro rata share is equal to the ratio of (a) the number of shares of the
Company's Common Stock (including all shares of Common Stock issued or issuable
upon conversion of the Shares) which such Right Holder is deemed to be a holder
immediately prior to the issuance of such Equity Securities to (b) the total
number of shares of the Company's outstanding Common Stock (including all shares
of Common Stock issued or issuable upon conversion of the Shares or upon the
exercise of any outstanding warrants, options or other rights) immediately prior
to the issuance of the Equity Securities. The term "Equity Securities" shall
mean (i) any capital stock of the Company, (ii) any security convertible, with
or without consideration, into capital stock of the Company (including any
option to purchase such a convertible security), (iii) any security carrying any
warrant or right to subscribe to or purchase any capital stock of the Company or
(iv) any such warrant or right.

         4.2 Exercise of Rights. If the Company proposes to issue any Equity
Securities, it shall give each Right Holder written notice of its intention,
describing the Equity Securities, the price and the terms and conditions upon
which the Company proposes to issue the same. Each Right Holder shall have
fifteen (15) days from the giving of such notice to agree to purchase its pro
rata share of

                                       19
<PAGE>

the Equity Securities for the price and upon the terms and conditions specified
in the notice by giving written notice to the Company and stating therein the
quantity of Equity Securities to be purchased. Notwithstanding the foregoing,
the Company shall not be required to offer or sell such Equity Securities to any
Right Holder who would cause the Company to be in violation of applicable
federal securities laws by virtue of such offer or sale.

         4.3 Issuance of Equity Securities to Other Right Holders. If not all of
the Right Holders elect to purchase their pro rata share of the Equity
Securities, then the Company shall first promptly notify in writing the Right
Holders who do so elect and shall offer such Right Holders the right to acquire
such unsubscribed shares. The fully participating Right Holders shall have five
(5) days after receipt of such notice to notify the Company of its election to
purchase all or a portion thereof of the unsubscribed shares. If the Right
Holders as a group, fail to exercise in full the rights of first refusal, the
Company shall have ninety (90) days thereafter to sell the Equity Securities in
respect of which the Right Holders' rights were not exercised, at a price and
upon general terms and conditions materially no more favorable to the purchasers
thereof than specified in the Company's notice to the Right Holders pursuant to
Section 4.2 hereof. If the Company has not sold such Equity Securities within
ninety (90) days of the notice provided pursuant to Section 4.2, the Company
shall not thereafter issue or sell any Equity Securities, without first offering
such securities to the Rights Holders in the manner provided above.

         4.4 Sale Without Notice. In lieu of giving notice to the Right Holders
prior to the issuance of Equity Securities as provided in Section 4.2, the
Company may elect to give notice to the Right Holders within thirty (30) days
after the issuance of Equity Securities. Such notice shall describe the type,
price and terms of the Equity Securities. Each Right Holders shall have twenty
(20) days from the date of receipt of such notice to elect to purchase its pro
rata share of Equity Securities (as defined in Section 4.1, and calculated

granted wholly or partly in Common Stock (including rights or options which may

in Paragraph 14. The Board and the appropriate officers of the Company shall

     5. Administration. This Plan shall be administered by the Committee, which
shall have full and exclusive power to interpret this Plan and to adopt such
rules, regulations and guidelines for carrying out this Plan as it may deem
necessary or proper, all of which powers shall be exercised in the best
interests of the Company and in keeping with the objectives of this Plan. The
Committee may correct any defect or supply any omission or reconcile any
inconsistency in this Plan or in any Award in the manner and to the extent the
Committee deems necessary or desirable to carry it into effect. Any decision of
the Committee in the interpretation and administration of this Plan shall lie
within its sole and absolute discretion and shall be final, conclusive and
binding on all parties concerned. No member of the Committee or officer of the
Company to whom it has delegated authority in accordance with the provisions of
Paragraph 6 of this Plan shall be liable for anything done or omitted to be done
by him or her, by any member of the Committee or by any officer of the Company
in connection with the performance of any duties under this Plan, except for his
or her own willful misconduct or as expressly provided by statute.

     6. Delegation of Authority. The Committee may delegate to the senior
officers of the Company its duties under this Plan pursuant to such conditions
or limitations as the Committee may establish, except that the Committee may not
delegate to any person the authority to grant Awards to, or take other action
with respect to, Participants who are subject to Section 16 of the Exchange Act.

     7. Awards. The Board or the Committee shall determine the type or types of
Awards to be made to each Participant under this Plan. Each Award made hereunder

                                       -3-
<PAGE>

embodied in an Award Agreement, which shall contain such terms, conditions and
limitations as shall be determined by the Committee in its sole discretion and
shall be signed by the Participant and by a senior officer of the Company to
whom the Committee has delegated such authority for and on behalf of the
Company. An Award Agreement may include provisions for the repurchase by the
Company of Common Stock acquired pursuant to the Plan and the repurchase of a
Participant's option rights under the Plan. Awards may consist of those listed
in this Paragraph 7 and may be granted singly, in combination or in tandem.
Awards may also be made in combination or in tandem with, in replacement of, or
as alternatives to grants or rights (a) under this Plan or any other employee
plan of the Company or any of its Subsidiaries, including the plan of any
acquired entity, or (b) made to any Company or Subsidiary employee by the
Company or any Subsidiary. An Award may provide for the granting or issuance of
additional, replacement or alternative Awards upon the occurrence of specified
events, including the exercise of the original Award. An Award Agreement may
include provisions for acceleration of the vesting and exercisability of and
lapse of restrictions with respect to Awards upon a Change of Control.
Notwithstanding anything herein to the contrary, no Participant may be granted
Awards consisting of stock options or stock appreciation rights exercisable for
more than 25% of the shares of Common Stock originally authorized for Awards
under this Plan, subject to adjustment as provided in Paragraph 14. In the event
of an increase in the number of shares authorized under the Plan, the 25%
limitation will apply to the number of shares authorized.

          (i) Stock Option. An Award may consist of a right to purchase a
     specified number of shares of Common Stock at a price specified by the
     Committee in the Award Agreement or otherwise. A stock option may be in the
     form of an incentive stock option ("ISO") which, in addition to being
     subject to applicable terms, conditions and limitations established by the
     Committee, complies with Section 422 of the Code, or in the form of a
     Nonqualified Option. Notwithstanding the foregoing, no ISO can be granted
     under the Plan more than ten years following the Effective Date of the
     Plan.

          (ii) Stock Appreciation Right. An Award may consist of a right to
     receive a payment, in cash or Common Stock, equal to the excess of the Fair
     Market Value or other specified valuation of a specified number of shares
     of Common Stock on the date the stock appreciation right ("SAR") is
     exercised over a specified strike price as set forth in the applicable
     Award Agreement.

                                       -4-
<PAGE>

          (iii) Stock Award. An Award may consist of Common Stock or may be
     denominated in units of Common Stock. All or part of any stock Award may be
     subject to conditions established by the Committee and set forth in the
     Award Agreement, which conditions may include, but are not limited to,
     continuous service with the Company and its Subsidiaries, achievement of
     specific business objectives, increases in specified indices, attaining
     specified growth rates and other comparable measurements of performance.
     Such Awards may be based on Fair Market Value or other specified
     valuations. The certificates evidencing shares of Common Stock issued in
     connection with a Stock Award shall contain appropriate legends and
     restrictions describing the terms and conditions of the restrictions
     applicable thereto.

          (iv) Cash Award. An Award may be denominated in cash with the amount
     of the eventual payment subject to future service and such other
     restrictions and conditions as may be established by the Committee and set
     forth in the Award Agreement, including, but not limited to, continuous
     service with the Company and its Subsidiaries, achievement of specific
     business objectives, increases in specified indices, attaining specified
     growth rates and other comparable measurements of performance.

     8. Payment of Awards.

          (a) General. Payment of Awards may be made in the form of cash or
     Common Stock or combinations thereof and may include such restrictions as
     the Committee shall determine including, in the case of Common Stock,
     restrictions on transfer and forfeiture provisions.

          (b) Deferral. The Committee may, in its discretion, (i) permit
     selected Participants to elect to defer payments of some or all types of
     Awards in accordance with procedures established by the Committee or (ii)
     provide for the deferral of an Award in an Award Agreement or otherwise.
     Any such deferral may be in the form of installment payments or a future
     lump sum payment. Any deferred payment, whether elected by the Participant
     or specified by the Award Agreement or by the Committee, may be forfeited
     if and to the extent that the Award Agreement so provides.

          (c) Dividends and Interest. Dividends or dividend equivalent rights
     may be extended to and made part of any Award denominated in Common Stock
     or units of Common Stock, subject to such terms, conditions and
     restrictions as the Committee may establish. The Committee may also
     establish rules and procedures for the crediting of interest on deferred
     cash payments and dividend equivalents for deferred payment denominated in
     Common Stock or units of Common Stock.

          (d) Substitution of Awards. At the discretion of the Committee, a
     Participant may be offered an election to substitute an Award for another
     Award or Awards of the same or different type.


                                       -5-
<PAGE>

     9. Stock Option Exercise. The price at which shares of Common Stock may be
purchased under a stock option shall be paid in full at the time of exercise in
cash or, if permitted by the Committee, by means of tendering Common Stock or
surrendering all or part of that or any other Award, including Restricted Stock,
valued at Fair Market Value on the date of exercise, or any combination thereof.
The Committee shall determine acceptable methods for tendering Common Stock or
Awards to exercise a stock option as it deems appropriate. If permitted by the
Committee, payment may be made by successive exercises by the Participant. The
Committee may provide for procedures to permit the exercise or purchase of
Awards by (a) loans from the Company or (b) use of the proceeds to be received
from the sale of Common Stock issuable pursuant to an Award. Unless otherwise
provided in the applicable Award Agreement, in the event shares of Restricted
Stock are tendered as consideration for the exercise of a stock option, a number
of the shares issued upon the exercise of the stock option, equal to the number
of shares of Restricted Stock used as consideration therefor, shall be subject
to the same restrictions as the Restricted Stock so submitted as well as any
additional restrictions that may be imposed by the Committee.

     10. Tax Withholding. The Company shall have the right to deduct applicable
taxes from any Award payment and withhold, at the time of delivery or vesting of
cash or shares of Common Stock under this Plan, an appropriate amount of cash or
number of shares of Common Stock or a combination thereof for payment of taxes
required by law or to take such other action as may be necessary in the opinion
of the Company to satisfy all obligations for withholding of such taxes. The
Committee may also permit withholding to be satisfied by the transfer to the
Company of shares of Common Stock theretofore owned by the holder of the Award
with respect to which withholding is required. If shares of Common Stock are
used to satisfy tax withholding, such shares shall be valued based on the Fair
Market Value when the tax withholding is required to be made.

     11. Amendment, Modification, Suspension or Termination. The Board may
amend, modify, suspend or terminate this Plan for the purpose of meeting or
addressing any changes in legal requirements or for any other purpose permitted
by law except that (a) no amendment or alteration that would impair the rights
of any Participant under any Award previously granted to such Participant shall
be made without such Participant's consent and (b) no amendment or alteration
shall be effective prior to approval by the Company's shareholders to the extent
such approval is then required pursuant to Rule 16b-3 in order to preserve the
applicability of any exemption provided by such rule to any Award then
outstanding (unless the holder of such Award consents) or to the extent
shareholder approval is otherwise required by applicable legal requirements.

     12. Termination of Employment or Service on the Board. Upon either the
termination of employment or the termination of service as a Director by a
Participant, any unexercised, deferred or unpaid Awards shall be treated as
provided in the specific Award Agreement evidencing the Award. Unless otherwise
specifically provided in the Award Agreement, each Award granted pursuant to
this Plan which is a stock option shall provide that if the Participant ceases
to be employed by the Company or its affiliates or, in the case of a
non-employee Director, to serve on the Board for any reason whatsoever, the
option shall immediately terminate to the extent the option is not vested (or
does not become vested as a result of such termination) on the date the
Participant terminates employment or service on the Board.

     13. Assignability. Except as otherwise provided herein, no Award granted
under this Plan shall be sold, transferred, pledged, assigned or otherwise
alienated or hypothecated by a Participant other than by will or the laws of
descent and distribution, and during the lifetime of a Participant, any Award
shall be exercisable only by the Participant, or, in the case of a Participant
who is mentally incapacitated, the Award shall be exercisable by the
Participant's guardian or legal representative. The Committee may prescribe and
include in applicable Award Agreements other restrictions on transfer. Any
attempted assignment or transfer in violation of this Paragraph 13 shall be null
and void. Upon the Participant's death, the personal representative or other
person entitled to succeed to the rights of the Participant (the "Successor
Participant") may exercise such rights. A Successor Participant must furnish
proof satisfactory to the Company of his or her right to exercise the Award
under the Participant's will or under the applicable laws of descent and
distribution.

     Subject to approval by the Committee in its sole discretion, all or a
portion of the Awards granted to a Participant under the Plan which are not
intended to be ISOs may be transferable by the Participant, to the extent and
only to the extent specified in such approval, to (i) the spouse, parent,
brother, sister, children or grandchildren of the Participant ("Immediate Family
Members"), (ii) a trust or trusts for the exclusive benefit of such Immediate
Family Members ("Immediate Family Member Trusts"), or (iii) a partnership or
partnerships in which such Immediate Family Members have at least 99% of the
equity, profit and loss interests ("Immediate Family Member Partnerships");
provided that the Award Agreement pursuant to which such Awards are granted (or
an amendment thereto) must expressly provide for transferability in a manner
consistent with this Section. Subsequent transfers of transferred Awards shall
be prohibited except by will or the laws of descent and distribution, unless
such transfers are made to the original Participant or a person to whom the
original Participant could have made a transfer in the manner described herein.
No transfer shall be effective unless and until written notice of such transfer
is provided to the Committee, in the form and manner prescribed by the
Committee. Following transfer, any such Awards shall continue to be subject to
the same terms and conditions as were applicable immediately prior to transfer,
and, except as otherwise provided herein, the term 'Participant' shall be deemed
to refer to the transferee. The events of termination of service in Paragraph 12
shall continue to be applied with respect to the original Participant, following
which the Awards shall be exercisable by the transferee only to the extent and
for the periods specified in this Plan and the Award Agreement.

     14. Adjustments.

          (a) The existence of outstanding Awards shall not affect in any manner
     the right or power of the Company or its shareholders to make or authorize
     any or all adjustments, recapitalizations, reorganizations or other changes
     in the capital stock of the Company or its business or any merger or
     consolidation of the Company, or any issue of bonds, debentures, preferred
     or prior preference stock (whether or not such issue is prior to, on a
     parity with or junior to the Common Stock) or the dissolution or
     liquidation of the Company, or any sale or transfer of all or any part of
     its assets or business, or any other corporate act or proceeding of any
     kind, whether or not of a character similar to that of the acts or
     proceedings enumerated above.


                                       -7-
<PAGE>

          (b) In the event of any subdivision or consolidation of outstanding
     shares of Common Stock or declaration of a dividend payable in shares of
     Common Stock or capital reorganization or reclassification or other
     transaction involving an increase or reduction in the number of outstanding
     shares of Common Stock, the Committee may adjust proportionally (i) the
     number of shares of Common Stock reserved under this Plan and covered by
     outstanding Awards denominated in Common Stock or units of Common Stock;
     (ii) the exercise or other price in respect of such Awards; and (iii) the
     appropriate Fair Market Value and other price determinations for such
     Awards. In the event of any consolidation or merger of the Company with
     another corporation or entity or the adoption by the Company of a plan of
     exchange affecting the Common Stock or any distribution to holders of
     Common Stock of securities or property (other than normal cash dividends or
     dividends payable in Common Stock), the Committee shall make such
     adjustments or other provisions as it may deem equitable, including
     adjustments to avoid fractional shares, to give proper effect to such
     event. In the event of a corporate merger, consolidation, acquisition of
     property or stock, separation, reorganization or liquidation, the Committee
     shall be authorized, in its discretion, (i) to issue or assume stock
     options, regardless of whether in a transaction to which Section 424(a) of
     the Code applies, by means of substitution of new options for previously
     issued options or an assumption of previously issued options, (ii) to make
     provision, prior to the transaction, for the acceleration of the vesting
     and exercisability of, or lapse of restrictions with respect to, Awards (to
     the extent not otherwise provided under paragraph 7) and the termination of
     options that remain unexercised at the time of such transaction or (iii) to
     provide for the acceleration of the vesting and exercisability of the
     options and SARs and the cancellation thereof (to the extent not otherwise
     provided under paragraph 7) in exchange for such payment as shall be
     mutually agreeable to the Participant and the Committee.

     15. Restrictions. No Common Stock or other form of payment shall be issued
with respect to any Award unless the Company shall be satisfied based on the
advice of its counsel that such issuance will be in compliance with applicable
federal and state securities laws. It is the intent of the Company that this
Plan comply with Rule 16b-3 with respect to persons subject to Section 16 of the
Exchange Act unless otherwise provided herein or in an Award Agreement, that any
ambiguities or inconsistencies in the construction of this Plan be interpreted
to give effect to such intention and that, if any provision of this Plan is
found not to be in compliance with Rule 16b-3, such provision shall be null and
void to the extent required to permit this Plan to comply with Rule 16b-3.
Certificates evidencing shares of Common Stock delivered under this Plan may be
subject to such stop transfer orders and other restrictions as the Committee may
deem advisable under the rules, regulations and other requirements of the
Securities and Exchange Commission, any securities exchange or transaction
reporting system upon which the Common Stock is then listed and any applicable
federal and state securities law. The Committee may cause a legend or legends to
be placed upon any such certificates to make appropriate reference to such
restrictions.

     16. Unfunded Plan. Insofar as it provides for Awards of cash, Common Stock
or rights thereto, this Plan shall be unfunded. Although bookkeeping accounts
may be established with respect to Participants who are entitled to cash, Common
Stock or rights thereto under this Plan, any such accounts shall be used merely
as a bookkeeping convenience. The Company shall not be required to segregate any
assets that may at any time be represented by cash, Common Stock or rights
thereto, nor shall this Plan be construed as providing for such segregation, nor
shall the

                                       -8-
<PAGE>

Company, the Board or the Committee be deemed to be a trustee of any cash,
Common Stock or rights thereto to be granted under this Plan. Any liability or
obligation of the Company to any Participant with respect to a grant of cash,
Common Stock or rights thereto under this Plan shall be based solely upon any
contractual obligations that may be created by this Plan and any Award
Agreement, and no such liability or obligation of the Company shall be deemed to
be secured by any pledge or other encumbrance on any property of the Company.
None of the Company, the Board or the Committee shall be required to give any
security or bond for the performance of any obligation that may be created by
this Plan.

     17. Parachute Payment Limitation. Notwithstanding any contrary provision of
the Plan, the Committee may provide in the Award Agreement for a limitation on
the acceleration of vesting and exercisability of unmatured Awards to the extent
necessary to avoid or mitigate the impact of the golden parachute excise tax
under Section 4999 of the Code on the Participant or may provide for a
supplemental payment to be made to the Participant as necessary to offset or
mitigate the impact of the golden parachute excise tax on the Participant. In
the event the Award Agreement does not contain any contrary provision regarding
the method of avoiding or mitigating the impact of the golden parachute excise
tax under Section 4999 of the Code on the Participant, then notwithstanding any
contrary provision of this Plan, the aggregate present value of all parachute
payments payable to or for the benefit of a Participant, whether payable
pursuant to this Plan or otherwise, shall be limited to three times the
Participant's base amount less one dollar and, to the extent necessary, the
exercisability of an unmatured Award shall be reduced in order that this
limitation not be exceeded. For purposes of this Section 17, the terms
"parachute payment," "base amount" and "present value" shall have the meanings
assigned thereto under Section 280G of the Code. It is the intention of this
Section 17 to avoid excise taxes on the Participant under Section 4999 of the
Code or the disallowance of a deduction to the Company pursuant to Section 280G
of the Code.

     18. Governing Law. This Plan and all determinations made and actions taken
pursuant hereto, to the extent not otherwise governed by mandatory provisions of
the Code or the securities laws of the United States, shall be governed by and
construed in accordance with the laws of the State of New York.

     19. Effective Date of Plan. This Plan shall be effective as of the date
(the "Effective Date") it is approved by the Board of Directors of the Company.
Notwithstanding the foregoing, the adoption of this Plan is expressly
conditioned upon the approval by written consent of the holders of a majority of
shares of outstanding shares of Common Stock on or before the first

                                       -9-
<PAGE>

anniversary of the Effective Date. If the shareholders of the Company should
fail so to approve this Plan prior to such date, this Plan shall terminate and
cease to be of any further force or effect and all grants of Awards hereunder
shall be null and void.

                                       Corporation as adopted by the Board of

                                                                    EXHIBIT 10.3

                                      LEASE

         THIS LEASE (the "Lease") is made and entered into as of the 6th day of
July 1999, by and between HV 645 Harrison, Inc., a California corporation (the
"Landlord"), and Linkshare Corporation, a Delaware corporation (the "Tenant").

1.       Premises

         (a) Subject to and upon the terms, covenants and conditions hereinafter
set forth, Landlord leases to Tenant and Tenant rents from Landlord those
certain premises as set forth in the Basic Lease Information attached hereto and
as approximately shown on the plan attached hereto as Exhibit A (the "Premises")
on the ground floor of the building located at 645 Harrison Street, San
Francisco, California (the "Building").

         (b) Tenant shall accept the Premises and the Building in their "as-is"
condition; provided, however, Landlord shall deliver the Premises in a broom
clean condition with the lighting, electrical and plumbing in good operating
condition. In addition Landlord shall repaint and recarpet the Premises with
paint and carpet mutually agreeable; provided the cost shall not exceed $17,400.
All alterations shall be performed in accordance with the terms of Section 9
below. Landlord acknowledges that Tenant is planning on demolishing non-load
bearing walls in the Premises as part of its initial construction of
improvements; and that Landlord shall not require the restoration of such walls
at the end of the term of this Lease.

2.       Term

         This Lease shall be for the term commencing on the Commencement Date
(provided Tenant shall have the right of access to the Premises upon the full
execution of this Lease, which access shall be governed by the terms of this
Lease, except the obligation to pay Base Rental) and expiring on the date that
is 48 and 1/2 months following the Commencement Date, unless sooner terminated
as provided herein (the "Term"). If Landlord, for any reason whatsoever, cannot
deliver possession of the Premises to Tenant on the date specified herein as the
Commencement Date, this Lease shall not be void or voidable, nor shall Landlord
be liable to Tenant for any loss or damage resulting therefrom. In that event,
however, Tenant shall not be liable for any Base Rental or Additional Charges
(as hereinafter defined) until Landlord delivers possession of the Premises to
Tenant.

3.       Rent

         (a) Tenant shall pay to Landlord "Base Rental" throughout the Term in
monthly installments as set forth in the Basic Lease Information attached
hereto, due and payable upon the first day of each and every month during the
Term, without any further notice from, or demand by Landlord and without any
offset or deduction whatsoever, in lawful money of the United States of America,
at the address set forth in the Basic Lease Information attached hereto or
elsewhere as designated from time to time by Landlord's written notice to
Tenant. Tenant shall also pay to
<PAGE>

Landlord all charges and other amounts whatsoever as provided in this Lease
("Additional Charges"); and such Additional Charges shall be payable to Landlord
at the place where the Base Rental is payable and Landlord shall have the same
remedies for a default in the payment of Additional Charges as for a default in
the payment of Base Rental. If the Commencement Date should occur on a day other
than the first day of a calendar month, or the Expiration Date should occur on a
day other than the last day of a calendar month, then the Base Rental and
Additional Charges for such fractional month shall be prorated on a daily basis.

         (b) Tenant recognizes that late payment of any Base Rental or
Additional Charges will result in additional administrative expense to Landlord
and will impair Landlord's ability to meet its obligations with respect to the
Building and otherwise, the exact extent of which additional expense and
impairment will be extremely difficult or impractical to determine. Tenant
therefore agrees that if any Base Rental or Additional Charges remain unpaid for
a period of five (5) days after the date the same is due, the amount of such
unpaid Base Rental or Additional Charges shall be increased by a late charge to
be paid to Landlord by Tenant in an amount equal to ten percent (10%) of the
amount of the past due Base Rental and/or Additional Charges. The amount of the
late charge to be paid to Landlord by Tenant on any delinquent Base Rental
and/or Additional Charges shall be reassessed and added to Tenant's obligation
for each successive monthly period accruing after the date on which the late
charge is initially imposed until such late charge and all delinquent Base
Rental and Additional Charges have been paid in full by Tenant. Tenant agrees
that such amount is a reasonable estimate of the loss and expense to be suffered
by Landlord as a result of any such late payment by Tenant. The provisions of
this Paragraph 3(b) in no way relieve Tenant of the obligation to pay Base
Rental or Additional Charges on or before the date on which they are due, nor do
the terms of this Paragraph 3(b) in any way affect Landlord's remedies pursuant
to Paragraph 18 in the event any Base Rental or Additional Charges are unpaid
after the date due.

4.       Additional Charges.  For purposes of this Paragraph 4, the following
terms shall have the meanings hereinafter set forth:

                  (i) "Base Year" shall mean the calendar year 2000.

                  (ii) "Taxes" shall mean all impositions, taxes, assessments
         (special or otherwise), and other governmental liens or charges of any
         kind or nature whatsoever, ordinary and extraordinary, foreseen and
         unforeseen, and any substitute therefor, including all taxes
         attributable in any manner to the Premises, the land on which the
         Premises is located or the rents (however the term may be defined)
         receivable therefrom or any charge or other payment required to be paid
         to any governmental authority, whether or not any of the foregoing
         shall be designated "real estate tax", "sales tax", "rental tax",
         "excise tax", "business tax", or designated in any other manner (except
         only those taxes of the following categories: any inheritance, estate
         succession, transfer or gift taxes imposed upon Landlord or any income
         taxes specifically payable by Landlord as a separate tax paying entity
         without regard to Landlord's income source as arising from or out of
         the Premises and/or the land on which it is located). Taxes shall also
         include reasonable legal fees, costs, and disbursements incurred in
         connection with proceedings to contest, determine, or reduce such
         Taxes.


                                        2
<PAGE>

                  (iii) "Operating Costs" shall mean all costs incurred by
         Landlord in connection with owning, operating and maintaining the
         Building. Operating Costs shall not include capital costs incurred by
         Landlord that are not required to be made to the Building by law or for
         the health and safety of the occupants of the Building.

                  (iv) "Tenant's Share" shall mean 4.3%.

         (a) Commencing upon January 1, 2001, tenant shall pay to Landlord as
Additional Charges, each month, an amount equal to Tenant's Share of any
increase in Taxes and Operating Costs from the Base Year.

         (b) Tenant shall pay, prior to delinquency, all taxes assessed against
and levied upon trade fixtures, furnishings, equipment and all other personal
property of Tenant contained in the Premises or elsewhere. When possible, Tenant
shall cause said trade fixtures, furnishings, equipment and all other personal
property to be assessed and billed separately from the real property of
Landlord. If any of Tenant's said personal property shall be assessed with
Landlord's real property, Tenant shall pay Landlord the taxes attributable to
Tenant within 10 days after receipt of a written statement setting forth the
taxes applicable to Tenant's property.

5.       Security Deposit and Letter of Credit

         Tenant concurrently with the execution of this Lease, has deposited
with Landlord the sum set forth in the Basic Lease Information attached hereto,
the receipt of which is hereby acknowledged by Landlord as security for the
faithful performance by Tenant of all terms, covenants and conditions of this
Lease. Tenant agrees that Landlord may apply the security deposit, after the
lapse of any applicable cure period, to remedy any failure by Tenant to repair
or maintain the Premises or to perform any other terms, covenants and conditions
contained herein or make any payment owing hereunder. If Tenant has kept and
performed all terms, covenants and conditions of this Lease during the Term,
Landlord will, within thirty (30) days after the expiration hereof, promptly
return the security deposit to Tenant or the last permitted assignee of Tenant's
interest hereunder. Should Landlord use any portion of the security deposit to
cure any default by Tenant hereunder, Tenant shall forthwith replenish the
security deposit to the original amount. Landlord shall not be required to keep
the security deposit separate from its general funds, and Tenant shall not be
entitled to interest on any such deposit. Upon the occurrence of any Events of
Default (as defined in Paragraph 18 of this Lease) the security deposit shall
become due and payable to Landlord to the extent required to compensate Landlord
for damages incurred, or to reimburse Landlord as provided herein, in connection
with any such Event of Default.

6.       Use and Compliance with Laws

         (a) Tenant shall use and occupy the Premises for general office and for
no other use or purpose.


                                        3
<PAGE>

         (b) Tenant shall not use the Premises or permit anything to be done in
or about the Premises that will in any way conflict with any law, statute,
ordinance or governmental rule or regulation now in force or which may hereafter
be enacted or promulgated. Tenant shall not do or permit anything to be done in
or about the Premises or bring or keep anything therein which will in any way
increase the rate of any insurance upon the Building or any of its contents or
cause a cancellation of such insurance or otherwise affect such insurance in any
manner, and Tenant shall at its sole cost and expense promptly comply with all
laws, statutes, ordinances and governmental rules, regulations or requirements
now in force or which may hereafter be in force and with the requirements of any
board of fire underwriters or other similar body now or hereafter constituted
relating to or affecting the condition, use or occupancy of the Premises,
excluding structural changes not related to or affected by alterations or
improvements made by Tenant or Tenant's use of the Premises.

7.       Hazardous Substances

         Except for Hazardous Substances on or in the Premises as of the
Commencement Date, Tenant will not cause, suffer or permit any Hazardous
Substance (as hereinafter defined) to be brought, kept or stored within the
Premises, and Tenant will not engage in or permit any other person to engage in
any activity, operation or business upon the Premises that involves the
generation, manufacture, refining, transportation, treatment, storage, handling
or disposal of any Hazardous Substance that would or could result in Tenant,
Landlord, the Premises, or the Building to be subject to any law, statute,
ordinance, or regulation or rule of common law pertaining to health, industrial
hygiene, or the environment. Tenant shall be responsible for any violation of
this Article 7 by any subtenant or other occupant of the Premises. The term
"Hazardous Substance" shall include, without limitation those substances,
materials and wastes that are or become regulated under applicable local, state
or federal law, or the United States government, or which are classified as
hazardous or toxic under federal, state, or local laws or regulations.

8.       Utilities and Janitorial

         Tenant shall pay for all water, gas, heat, light, power, telephone and
other utilities and services supplied to the Premises, together with any taxes
thereon. If any such services are not separately metered to Tenant, Tenant shall
pay a reasonable proportion to be determined by Landlord of all charges jointly
metered with other premises based upon estimated usage of each tenant. Tenant,
at Tenant's sole cost, shall be responsible for providing janitorial services to
the Premises.

9.       Alterations

         Tenant shall not make any alternations, additions or improvements
(collectively, "Alterations") in or to the Premises without the prior written
consent of Landlord, which shall not be unreasonably withheld, but may be
predicated upon but not limited to Tenant's use of contractors who are
reasonably acceptable to Landlord; and any Alterations, except for Tenant's
movable furniture and equipment, at Landlord's election, shall immediately
become Landlord's property and,


                                        4
<PAGE>

at the end of the Term, shall remain on the Premises without compensation to
Tenant or, if Landlord shall elect, be removed by Tenant prior to the expiration
date of this Lease. All Alterations shall be completed in compliance with all
laws, codes, rules, and ordinances in effect at the time of such Alterations. In
the event the making of any Alterations triggers any additional work to be
performed to the Premises or the Building, such additional work shall be
performed at Tenant's sole cost and expense. In the event Tenant fails to remove
any Alterations required by Landlord to be removed, Landlord may remove such
Alterations and Tenant shall be obligated to immediately reimburse Landlord for
the cost therefor. In the event Landlord consents to the making of any
Alterations by Tenant, the same shall be made by Tenant, at Tenant's sole cost
and expense, in accordance with plans and specifications approved by Landlord,
and any contractor or person selected by Tenant to make the same must first be
approved in writing by Landlord, such approval not to be unreasonably withheld
or delayed. Upon the expiration or sooner termination of the Term, Tenant shall
upon written demand by Landlord (to be provided at the time such approval for
Alterations is requested) and at Tenant's sole cost and expense, promptly remove
any Alterations made by or for the account of Tenant that are designated by
Landlord to be removed, and Tenant shall at its sole cost and expense, promptly
repair and restore the Premises to its original condition.

10.      Repair

         (a) Tenant shall take good care of the Premises and, at Tenant's cost
and expense, shall make all repairs and replacements to preserve the Premises in
good working order and condition normal wear and tear and damage due to casualty
excepting, except that Tenant shall not be required to make any such structural
repairs or structural replacements unless necessitated or occasioned by the
acts, omissions or negligence of Tenant, or any of its employees, contractors,
agents or invitees, or by the manner of Tenant's use or occupancy of the
Premises. Landlord shall not be liable for and there shall be no abatement of
Base Rental or Additional Charges with respect to any injury to or interference
with Tenant's business arising from any repairs, maintenance, alteration or
improvement in or to any portion of the Building, including the Premises, or in
or to the fixtures, appurtenances and equipment therein. Landlord shall use its
reasonable effort to perform any repairs, maintenance, alterations or
improvements of things and in a manner so as to minimize any disturbance to
Tenant. Tenant hereby waives and releases its right to make repairs at
Landlord's expense under Sections 1941 and 1942 of the California Civil Code or
under any similar law, statute or ordinance now or hereafter in effect. In
addition, Tenant hereby waives and releases its right to terminate this Lease
under Section 1932(1) of the California Civil Code or under any similar law,
statute or ordinance now or hereafter in effect.

         (b) All repairs and replacements made by or on behalf of Tenant or any
person claiming through or under Tenant shall be made and performed (i) at
Tenant's sole cost and expense and at such time and in such manner as Landlord
may reasonably designate, (ii) by contractors or mechanics reasonably approved
by Landlord, (iii) so that same shall be at least equal in quality, value, and
utility to the original work or installation, (iv) in accordance with the
reasonable rules and regulations for the Building adopted by Landlord from time
to time, and (v) in accordance with all applicable laws and regulations of
governmental authorities having jurisdiction over the Premises.

11.      Liens

         Tenant shall keep the Premises free from any liens arising out of any
work performed, material furnished or obligations incurred by Tenant. In the
event that Tenant shall not, within ten (10) days following the imposition of
any such lien, cause the same to be released of record by payment or posting of
a proper bond, Landlord shall have, in addition to all other remedies provided
herein and by law, the right, but not the obligation, to cause the same to be
released by such means as it shall deem proper, including payment of the claim
giving rise to such lien. All such sums paid by Landlord and all expenses
incurred by it in connection therewith shall be considered Additional Charges
and shall be payable to it by Tenant on demand with interest at the maximum rate
permitted by law. Landlord shall have the right at all times to post and keep
posted on the Premises any notices permitted or required by law, or which
Landlord shall deem proper, for the protection of Landlord, the Premises and the
Building from mechanics' and materialmen's liens, and Tenant shall give to
Landlord at least five (5) business days' prior notice of commencement of any
construction in the Premises.

12.      Assignment and Subletting

         (a) Tenant shall not directly or indirectly, voluntarily or by
operation of law, sell, assign, encumber, pledge or otherwise transfer or
hypothecate all or any part of the Premises or Tenant's leasehold estate
hereunder (collectively, "Assignment"), or permit the Premises to be occupied by
anyone other than Tenant or sublet the Premises or any portion thereof
(collectively, "Sublease") without Landlord's prior written consent in each
instance, which consent may not be unreasonably withheld by Landlord.

         (b) Without limiting the other instances in which it may be reasonable
for Landlord to withhold its consent to an Assignment or Sublease, Landlord and
Tenant acknowledge that it shall be reasonable for Landlord to withhold its
consent in, the following instances:

                  (i) if at the time consent is requested or at any time prior
         to the granting of consent, Tenant is in default under this Lease or
         would be in default under this Lease but for the pendency of any grace
         or cure period under Paragraph 18 below;

                  (ii) if the proposed assignee or sublessee is a governmental
         agency;

                  (iii) if, in Landlord's judgment, the use of the Premises by
         the proposed assignee or sublessee would not be compatible to the types
         of use by other tenants in the Building, would entail any alterations
         which would lessen the value of the leasehold improvements in the
         Premises, would result in more than a reasonable number of occupants
         per floor, would require unreasonable increased services by Landlord or
         would conflict with any so-called "exclusive" or percentage lease then
         in favor of another tenant of the Building;


                                        6
<PAGE>

                  (iv) if, in Landlord's reasonable judgment, the financial
         strength of the proposed assignee or sublessee does not meet the credit
         standards applied by Landlord for other tenants under leases with
         comparable terms, or the character, reputation, or business of the
         proposed assignee or sublessee is not consistent with the quality of
         the other tenancies in the Building;

                  (v) if the Sublease would result in the division of the
         Premises into three or more units; or

                  (vi) if the proposed assignee or sublessee is an existing
         tenant of the Building or Landlord is currently marketing space in the
         Building to such proposed assignee or sublessee.

         (c) If Tenant desires at any time to enter into an Assignment or
Sublease, it shall first give written notice ("Tenant's Notice") to Landlord of
its desire to do so, which notice shall contain (i) the name of the proposed
assignee or subtenant, (ii) the terms and provisions of the proposed Assignment
or Sublease, and (iii) such financial information as Landlord may reasonably
request concerning the proposed assignee or subtenant.

         (d) If Landlord consents by delivery a written notice to Tenant, to an
Assignment or a Sublease within fifteen (15) days of receipt of Tenant's Notice,
Tenant may thereafter, within ninety (90) days after Landlord's consent, but not
later than the expiration of said ninety (90) days, enter into such Assignment
or Sublease, upon the terms and conditions set forth in the notice furnished by
Tenant to Landlord pursuant to Paragraph 12(c).

         (e) In the case of an Assignment, fifty percent (50%) of any sums or
other, economic consideration received by Tenant as a result of such Assignment
shall be paid to Landlord, after deducting the cost to Tenant of any
improvements made for such Assignment and the cost to Tenant of any broker fees
in connection with such Assignment. In the case of a Sublease, fifty percent
(50%) of any sums or economic consideration received by Tenant as a result of
such Sublease shall be paid to Landlord after first deducting the rental due
hereunder and after deducting the cost to Tenant of any improvements made for
such Assignment and the cost to Tenant of any broker fees in connection with
such Assignment, prorated to reflect only rental allocable to the sublet portion
of the Premises.

         (f) Notwithstanding any of the above provisions of this Section to the
contrary, if Tenant notifies Landlord that it desires to enter into a Transfer,
Landlord, in lieu of consenting to such Assignment or Sublease, may elect (x) in
the case of an assignment or a sublease of the entire Premises, to terminate
this Lease, or (y) in the case of a sublease of less than the entire Premises,
to terminate this Lease as it relates to the space proposed to be subleased by
Tenant. In such event, this Lease will terminate (or the space proposed to be
subleased will be removed from the Premises subject to this Lease and the Base
Rent and Tenant's Share under this Lease shall be proportionately reduced) on
the date the Transfer was proposed to be effective, and Landlord may lease such
space to any party, including the prospective Transferee identified by Tenant.


                                        7
<PAGE>

         (g) No consent by Landlord to any Assignment or Sublease by Tenant
shall relieve Tenant of any obligation to be performed by Tenant under this
Lease, whether arising before or after the Assignment or Sublease. The consent
by Landlord to any Assignment or Sublease shall not relieve Tenant from the
obligation to obtain Landlord's express written consent to any other Assignment
or Sublease. Any Assignment or Sublease that is not in compliance with this
Paragraph 12 shall be void and, at the option of Landlord, shall constitute a
material default by Tenant under this Lease. The acceptance of Base Rental or
Additional Charges by Landlord from a proposed assignee or sublessee shall not
constitute the consent to such Assignment or Sublease by Landlord.

         (h) Any sale or other transfer, including by consolidation, merger or
reorganization of a majority of the voting stock of Tenant, if Tenant is a
corporation, shall not be an Assignment for purposes of this Paragraph 12.

         (i) Each assignee of this Lease shall assume all obligations of Tenant
under this Lease and shall be and remain liable jointly and severally with
Tenant for the payment of Base Rental and Additional Charges, and for the
performance of all the terms, covenants and conditions herein contained on
Tenant's part to be performed. No Assignment shall be binding on Landlord unless
the assignee or Tenant shall deliver to Landlord a counterpart of the Assignment
and an instrument in recordable form that contains a covenant of assumption by
the assignee satisfactory in substance and form to Landlord, but the failure or
refusal of the assignee to execute such instrument of assumption shall not
release or discharge the assignee from its liability as set forth above.

13.      Insurance and Indemnification

         (a) Except to the extent caused by the gross negligence of Landlord,
Tenant agrees to defend, protect and indemnify Landlord against and save
Landlord harmless from any and all loss, cost, liability, damage and expense,
including without limitation, penalties, fines and reasonable counsel fees and
disbursements, incurred in connection with or arising from any cause whatsoever
in, on or about the Premises, including without limiting the generality of the
foregoing: (i) any default by Tenant in the observance or performance of any of
the terms, covenants or conditions of this Lease on Tenant's part to be observed
or performed, or (ii) the use or occupancy or manner of use or occupancy of the
Premises by Tenant or any person or entity claiming through or under Tenant, or
(iii) the condition of the Premises or any occurrence or happening on the
Premises from any cause whatsoever, or (iv) any sots, omissions or negligence of
Tenant or any person or entity claiming through or under Tenant, or of the
contractors, agents, servants, employees, visitors or licensees of Tenant or any
such person or entity, in, on or about the Premises or the Building, either
prior to the commencement of, during, or after the expiration of the Term,
including without limitation any acts, omissions or negligence in making or
performing any Alterations. In the event any action or proceeding is brought
against Landlord for any claim against which Tenant is obligated to indemnify
Landlord hereunder, Tenant upon notice from Landlord shall defend such action or
proceeding at Tenant's sole expense by counsel selected by Landlord. The
provisions of this


                                        8
<PAGE>

Paragraph 13 shall survive the expiration or termination of this Lease with
respect to any claims or liability occurring prior to such expiration or
termination.

         (b) Tenant shall procure at its cost and expense and keep in effect
during the Term commercial general liability insurance including contractual
liability with a minimum combined single limit of liability of Two Million
Dollars ($2,000,000.00) or such greater amount as Landlord may reasonably
specify from time to time by written notice to Tenant. Such insurance shall name
Landlord and the current property manager of the Building as additional insured,
shall specifically include the liability assumed hereunder by Tenant (provided
that the amount of such insurance shall not be construed to limit the liability
of Tenant hereunder), and shall provide that it is primary insurance, and not
excess over or contributory with any other valid, existing and applicable
insurance in force for or on behalf of Landlord, and shall provide that Landlord
shall receive thirty (30) days' written notice from the insurer prior to any
cancellation or change of coverage. Tenant shall deliver policies of such
insurance or certificates thereof to Landlord on or before the Commencement
Date, and thereafter at least thirty (30) days before the expiration dates of
expiring policies; and, in the event Tenant shall fail to procure such
insurance, or to deliver such policies or certificates, Landlord may, at its
option, procure the same for the account of Tenant, and the cost thereof shall
be paid to Landlord as Additional Charges within five (5) days after delivery to
Tenant of bills therefor. Tenant's compliance with the provisions of this
Paragraph 13(b) shall in no way limit Tenant's liability under any of the other
provisions of this Paragraph 13.

         (c) Landlord shall procure and keep in effect during the Term casualty
insurance insuring the Building, excluding any improvements or Alterations made
by Tenant, and Tenant shall pay Tenant's Share of the annual cost within thirty
days after receipt of an invoice from Landlord.

14.      Waiver of Subrogation

         Landlord and Tenant shall each obtain from their respective insurers
under all policies of fire, theft, public liability, workers' compensation and
other insurance maintained by either of them at any time during the Term
insuring or covering the Building or any portion thereof or operations therein,
a waiver of all rights of subrogation which the insurer of one party might
otherwise have against the other party, and Landlord and Tenant shall each
indemnify the other against any loss or expense, including reasonable attorneys'
fees, resulting from the failure to obtain such waiver.

15.      Damage and Destruction

         If the Premises or the Building are damaged by fire or other casualty,
Landlord shall forthwith repair the same, provided that such repairs can be made
within ninety (90) days after the date of such damage under the laws and
regulations of the federal, state and local governmental authorities having
jurisdiction thereof. In such event, this Lease shall remain in full force end
effect except that Tenant shall be entitled to a proportionate reduction of Base
Rental based upon the extent to which such damage and the making of such repairs
by Landlord shall interfere with the business carried on by Tenant in the
Premises. Within twenty (20) days after the date of such damage,


                                        9
<PAGE>

Landlord shall notify Tenant whether or not such repairs can be made within
ninety (90) days after the date of such damage. If such repairs cannot be made
within ninety (90) days from the date of such damage, Landlord and Tenant shall
each have the option within thirty (30) days after the date of such damage to
terminate this Lease as of a date specified in such notice, which date shall be
not less than thirty (30) nor more than sixty (60) days after notice is given.
In case of termination, the Base Rental shall be reduced by a proportionate
amount based upon the extent to which such damage interfered with the business
carried on by Tenant in the Premises, and Tenant shall pay such reduced Base
Rental up to the date of termination. The repairs to be made hereunder by
Landlord shall not include, and Landlord shall not be required to repair, any
damage to the property of Tenant. Tenant hereby waives the provisions of Section
1932, subdivision 2, and Section 1933, subdivision 4, of the Civil Code of
California.

16.      Eminent Domain

         If any part of the Premises shall be taken or appropriated under the
power of eminent domain such that the balance of the Premises is rendered
unsuitable for its intended use, either party shall have the right to terminate
this Lease at its option. If any part of the Building shall be taken or
appropriated under power of eminent domain, Landlord may terminate this Lease at
its option upon at least thirty (30) days notice to Tenant. In either of such
events, Landlord shall receive (and Tenant shall assign to Landlord upon demand
from Landlord) any income, rent, award or any interest therein which may be paid
in connection with the exercise of such power of eminent domain provided,
however, that Tenant may receive the portion of the sum paid by virtue of such
proceedings to Tenant in its own right for relocation expenses and damage to
Tenant's personal property. If a part of the Premises shall be so taken or
appropriated and such taking or appropriation does not render the balances of
the Premises unsuitable for its intended use or neither party hereto elects to
terminate this Lease, and if the Premises have been damaged as a consequence of
such partial taking or appropriation, Landlord shall restore the Premises
continuing under this Lease at Landlord's cost and expense. Thereafter, the Base
Rental to be paid under this Lease for the remainder of the term shall be
proportionately reduced, such reduction to be based upon the extent to which the
partial taking or appropriation shall interfere with the business carried on by
Tenant in the Premises. Notwithstanding anything to the contrary contained in
this Paragraph 16, in the case of any temporary taking of any part of the
Premises during the Term, this Lease shall be and remain unaffected by such
temporary taking and Tenant shall continue to pay in full the Base Rental
payable hereunder, and Tenant shall be entitled to receive that portion of any
award which represents compensation for the use of or occupancy of the Premises
during the Term, and Landlord shall be entitled to receive that portion of any
award which represents the cost of restoration of the Premises and the use and
occupancy of the Premises after the end of the Term.

17.      Right of Entry

         Landlord, or any of its agents, shall have the right to enter the
Premises during all reasonable hours to examine the same or to make such
repairs, additions or alterations as may be deemed


                                       10
<PAGE>

necessary for the safety, comfort, or preservation thereof, or of the Building,
or to exhibit the Premises at any time within one hundred eight (180) days
before the expiration of this Lease.

18.      Events of Default and Remedies

         (a) The occurrence of any one or more of the following events ("Event
of Default") shall constitute a breach of this Lease by Tenant:

                  (i) Tenant fails to pay any Base Rental under this Lease as
         and when such rent becomes due and payable and such failure continues
         for more than five (5) days after Landlord gives written notice thereof
         to Tenant; provided, however, that after the second such failure in a
         calendar year, only the passage of time, but no further notice, shall
         be required to establish an Event of Default in the same calendar year;
         or

                  (ii) Tenant fails to pay any Additional Charges or other
         amount of money or charge payable by Tenant hereunder as and when such
         Additional Charges or amount or charge becomes due and payable and such
         failure continues for more than ten (10) days after Landlord gives
         written notice thereof to Tenant; provided, however, that after the
         second such failure in a calendar year, only the passage of time, but
         no further notice, shall be required to establish an Event of Default
         in the same calendar year; or

                  (iii) Tenant fails to perform or breaches any other agreement
         or covenant of this Lease to be performed or observed by Tenant as and
         when performance or observance is due and such failure or breach
         continues for more than ten (10) days after Landlord gives written
         notice thereof to Tenant; provided, however, that if, by the nature of
         such agreement or covenant, such failure or breach cannot reasonably be
         cured within such period of ten (10) days, an Event of Default shall
         not exist as long as Tenant commences with due diligence and dispatch
         the curing of such failure or breach within such period of ten (10)
         days and, having so commenced, thereafter prosecutes with diligence and
         dispatch and completes the curing of such failure or broach; or

                  (iv) Tenant (A) files, or consents by answer or otherwise to
         the filing against it of, a petition for relief or reorganization or
         arrangement or any other petition in bankruptcy or for liquidation or
         to take advantage of any bankruptcy, insolvency or other debtors'
         relief law of any jurisdiction, (B) makes an assignment for the benefit
         of its creditors, (C) consents to the appointment of a custodian,
         receiver, trustee or other officer with similar powers of Tenant or of
         any substantial part of Tenant's property, or (D) takes action for the
         purpose of any of the foregoing; or

                  (v) Without consent by Tenant, a court or government authority
         enters an order, and such order is not vacated within thirty (30) days,
         (A) appointing a custodian, receiver, trustee or other officer with
         similar powers with respect to Tenant or with respect to any
         substantial part of Tenant's property, or (B) constituting an order for
         relief or approving a petition for relief or reorganization or
         arrangement or any other petition in bankruptcy or for liquidation or
         to take


                                       11
<PAGE>

         advantage of any bankruptcy, insolvency or other debtors' relief law of
         any jurisdiction, or (C) ordering the dissolution, winding-up or
         liquidation of Tenant; or

                  (vi) This Lease or any estate of Tenant hereunder is levied
         upon under any attachment or execution and such attachment or execution
         is not vacated within thirty (30) days; or

                  (vii) Tenant intentionally abandons the Premises.

         (b) If an Event of Default occurs, Landlord shall have the right at any
time to give a written termination notice to Tenant and, on the date specified
in such notice, Tenant's right to possession shall terminate and this Lease
shall terminate. Upon such termination, Landlord shall have the right to recover
from Tenant:

                  (i) The worth at the time of award of all unpaid rent which
         had been earned at the time of termination;

                  (ii) The worth at the time of award of the amount by which all
         unpaid rent which would have been earned after termination until the
         time of award exceeds the amount of such rental loss that Tenant proves
         could have been reasonably avoided;

                  (iii) The worth at the time of award of the amount by which
         all unpaid rent for the balance of the term of this Lease after the
         time of award exceeds the amount of such rental loss that Tenant proves
         could be reasonably avoided; and

                  (iv) All other amounts necessary to compensate Landlord for
         all the detriment proximately caused by Tenant's failure to perform all
         of Tenant's obligations under this Lease or which in the ordinary
         course of things would be likely to result therefrom. The "worth at the
         time of award" of the amounts referred to in clauses (i) and (ii) above
         shall be computed by allowing interest at the maximum annual interest
         rate allowed by law for business loans (not primarily for personal,
         family or household purposes) not exempt from the usury law at the time
         of termination or, if there is no such maximum annual interest rate, at
         the rate of eighteen percent (18%) per annum. The "worth at the time of
         award" of the amount referred to in clause (iii) above shall be
         computed by discounting such amount at the discount rate of the Federal
         Reserve Bank of San Francisco at the time of award plus one percent
         (1%). For the purpose of determining unpaid rent under clauses (i),
         (ii) and (iii) above, the rent reserved in this Lease shall be deemed
         to be the total rent payable by Tenant under Paragraphs 3 and 4 hereof.

         (c) Notwithstanding the occurrence of an Event of Default, pursuant to
California Civil Code ss. 1954.1, or any successor statute thereof, this Lease
shall continue in effect for so long as Landlord does not terminate Tenant's
right to possession, and Landlord shall have the right to enforce all its rights
and remedies under this Lease, including the right to recover all rent as it
becomes due under this Lease. Acts of maintenance or preservation or efforts to
relet the Premises or the appointment of a receiver upon initiative of Landlord
to protect Landlord's interest under this


                                       12
<PAGE>

Lease shall not constitute a termination of Tenant's right to possession unless
written notice of termination is given by Landlord to Tenant.

         (d) The remedies provided for in this Lease are in addition to all
other remedies available to Landlord at law or in equity by statute or
otherwise.

         (e) All agreements and covenants to be performed or observed by Tenant
under this Lease shall be at Tenant's sole cost and expense and without any
abatement of Base Rental and Additional Charges. If Tenant fails to pay any sum
of money to be paid by Tenant or to perform any other act to be performed by
Tenant under this Lease, Landlord shall have the right, but shall not be
obligated, and without waiving or releasing Tenant from any obligations of
Tenant, to make any such payment or to perform any such other act on behalf of
Tenant in accordance with this Lease. All sums so paid by Landlord and all
necessary incidental costs shall be deemed Additional Charges hereunder and
shall be payable by Tenant to Landlord on demand, together with interest on all
such sums from the date of expenditure by Landlord to the date of repayment by
Tenant at the maximum annual interest rate allowed by law for business loans
(not primarily for personal, family or household purposes) not exempt from the
usury law at the date of expenditure or, if there is no such maximum annual
interest rate, at the rate of eighteen percent (18%) per annum. Landlord shall
have, in addition to all other rights and remedies of Landlord, the same rights
and remedies in the event of the nonpayment of such sums plus interest by Tenant
as in the case of default by Tenant in the payment of Base Rental.

         (f) If Tenant abandons or surrenders the Premises, or is dispossessed
by process of law or otherwise, any movable furniture, equipment, trade fixtures
or personal property belonging to Tenant and left in the Premises shall be
deemed to be abandoned, at the option of Landlord, and Landlord shall have the
right to sell or otherwise dispose of such personal property in any commercially
reasonable manner.

19.      Right of Landlord to Perform

         All covenants and agreements to be performed by Tenant under any of the
terms of this Lease shall be performed by Tenant at Tenant's sole cost and
expense and without any abatement of Base Rental or Additional Charges. If
Tenant shall fail to pay any sum of money, other than Base Rental or Additional
Charges, required to be paid by it hereunder or shall fail to perform any other
act on its part to be performed hereunder, and such failure shall continue for
ten (10) days after notice thereof by Landlord, Landlord may, but shall not be
obligated to do so, and without waiving or releasing Tenant from any obligations
of Tenant, make any such payment or perform any such act on Tenant's part to be
made or performed as provided in this Lease. All sums so paid by Landlord and
all necessary incidental costs together with interest thereon at the maximum
rate permitted by law, from the date of such payment by Landlord shall be
payable as Additional Charges to Landlord on demand.


                                       13

20.      Notices

         Any notices under this Lease shall be effective only if given in
writing, sent by certified mail or delivered personally, (a) to Tenant (i) at
the address designated for such notices in the Basic Lease Information attached
hereto, if sent prior to Tenant's taking possession of the Premises, or (ii) at
the Premises if sent subsequent to Tenant's taking possession of the Premises,
or (iii) at any place where Tenant may be found if sent subsequent to Tenant's
vacating, deserting, abandoning or surrendering the Premises, and (b) to
Landlord at the address set forth in the Basic Lease Information, or (c) to such
other address as either Landlord or Tenant may designate as its new address for
such purpose by notice given to the other in accordance with the provisions of
this Paragraph 20. Any notice shall be deemed to have been given two (2) days
after the date when it shall have been mailed or upon the date personal delivery
is made. If Tenant is notified of the identity and address of any mortgagee,
Tenant shall give to such mortgagee notice of any default by Landlord under the
terms of this Lease in writing sent by certified mail, and such mortgagee shall
be given a reasonable opportunity to cure such default prior to Tenant's
exercising any remedy available to it.

21.      Quiet Enjoyment

         Upon the payment by Tenant of all Base Rental and Additional Charges
due hereunder, and upon performance by Tenant of all of the terms, covenants and
conditions on Tenant's part to be observed and performed, Tenant shall peaceably
and quietly hold and enjoy the Premises for the Term hereby demised, subject to
all of the terms, covenants and conditions of this Lease.

22.      Subordination and Attornment

         (a) This Lease shall be subject and subordinate at all times to the
lien of all mortgages and deeds of trust securing any amount or amounts
whatsoever which may now exist or hereafter be placed on or against the Building
or on or against Landlord's interest or estate therein, all without the
necessity of having further instruments executed by Tenant to effect such
subordination. Notwithstanding the foregoing, in the event of a foreclosure of
any such mortgage or deed of trust or of any other action or proceeding for the
enforcement thereof, or of any sale thereunder, this Lease shall not be
terminated or extinguished, nor shall the rights and possession of Tenant
hereunder be disturbed, if no Event of Default then exists under this Lease, and
Tenant shall attorn to the person or entity that acquires Landlord's interest
hereunder through any such mortgage or deed of trust. Tenant agrees to execute,
acknowledge and deliver upon demand such further instruments evidencing such
subordination of this Lease to the lien of all such mortgages and deeds of trust
as may reasonably be required by Landlord. Landlord shall use its reasonable
efforts to obtain a non-disturbance agreement from any current lender.

         (b) The voluntary or other surrender of this Lease by Tenant, or a
mutual cancellation thereof, shall not work a merger and shall, at the option of
Landlord, terminate all or any existing subleases or subtenancies or operate as
an assignment to Landlord of any or all such subleases or subtenancies.


                                       14

         (c) If the original Landlord hereunder, or any successor owner of the
Building, sells or conveys the Building, all liabilities and obligations on the
part of the original Landlord, or such successor owner, under this Lease
accruing after such sale or conveyance shall terminate and the original
Landlord, or such successor owner, shall automatically be released therefrom,
and thereupon all such liabilities and obligations shall be binding upon the new
owner. Tenant agrees to attorn to such new owner.

23.      Tenant's Certificates

         From time to time upon not less than ten (10) days' prior written
notice from Landlord, Tenant will execute and deliver to Landlord a certificate
of Tenant stating: (a) that Tenant has accepted the Premises (or, if Tenant has
not done so, that Tenant has not accepted the Premises and specifying the
reasons therefor), (b) the Commencement and Expiration Dates of this Lease, (c)
that this Lease is unmodified and in full force and effect (or, that there have
been modifications), (d) whether or not there are then existing any defenses
against the enforcement of any of the obligations of Tenant under this Lease
(and, if so specifying same), (e) whether or not there are then existing any
defaults by Landlord in the performance of its obligations under this Lease
(and, if so, specifying same), (f) the dates, if any, to which the Base Rental
and Additional Charges under this Lease have been paid, and (g) any other
information that may reasonably be required by Landlord. It is intended that any
such certificate of Tenant delivered pursuant to this Paragraph 23 may be relied
upon by Landlord and any prospective purchaser or mortgagee of the Building or
any portion thereof. Tenant's failure to execute and deliver such certificate to
Landlord within ten (10) days of Landlord's written notice shall constitute a
certification by Tenant (i) that Tenant has accepted the Premises, (ii) that
there are no existing defenses against the enforcement of the obligations of
Tenant under the Lease, and (iii) that there are no existing defaults by
Landlord in the performance of its obligations under the Lease. In addition,
Tenant's failure to execute and deliver such certificate to Landlord with ten
(10) days of Landlord's written notice shall constitute a certification by
Tenant that the information required in (b), (c), (f) and (g) of this Paragraph
23 to be included in the certificate of Tenant is as indicated by Landlord in
writing to any prospective purchaser or mortgagee of any part of the Building or
the land upon which the Building is located, if such a writing is provided by
Landlord as a result of Tenant's failure to timely provide a tenant's
certificate pursuant to this Paragraph 23.

24.      Successors and Assigns

         Subject to the provisions of Paragraph 12, the terms, covenants and
conditions contained in this Lease shall be binding upon and inure to the
benefit of the parties hereto and their respective legal and personal
representatives, successors and assigns.

25.      Attorneys' Fees

         If either party defaults in the performance of any of the terms,
covenants and conditions of this Lease and by reason thereof the other party
employs the services of an attorney to enforce


                                       15
<PAGE>

performance of the covenants, or to perform any service based upon defaults,
then in any of said events the prevailing party shall be entitled to reasonable
attorneys' fees and all expenses and costs incurred by the prevailing party
pertaining thereto (including costs and fees relating to any appeal) and in
enforcement of any remedy.

26.      Waiver

         If either Landlord or Tenant waives the performance of any term,
covenant or condition contained in this Lease, such waiver shall not be deemed
to be a waiver of any subsequent breach of the same or any other term, covenant
or condition contained herein. Furthermore, the acceptance of Base Rental or
Additional Charges by Landlord shall not constitute a waiver of any preceding
breach by Tenant of any term, covenant or condition of this Lease, regardless of
Landlord's knowledge of such preceding breach at the time Landlord accepted such
Base Rental or Additional Charges. Failure by Landlord to enforce any of the
terms, covenants or conditions of this Lease for any length of time shall not be
deemed to waive or to decrease the right of Landlord to insist thereafter upon
strict performance by Tenant. Waiver by Landlord of any term, covenant or
condition contained in this Lease may only be made by a written document signed
by Landlord.

27.      Surrender of Premises

         At the end of the Term or sooner termination of this Lease, Tenant will
peaceably deliver to Landlord possession of the Premises, together with all
improvements or additions upon or belonging to same, by whomsoever made, in the
same condition as received or first installed, damage by fire, earthquake, Act
of God, or the elements alone excepted. Upon the termination of this Lease,
Tenant shall repair any damage caused by such removal. Property not so removed
shall be deemed abandoned by Tenant, and title to the same shall thereupon pass
to Landlord.

28.      Holding Over

         Any holding over after the expiration of the Term with the consent of
Landlord shall be construed to be a tenancy from month to month at a monthly
Base Rental equal to two hundred percent (200%) of the Base Rental for last
month of the Term of this Lease, and shall otherwise be on the terms and
conditions herein specified so far as applicable. Any holding over without
Landlord's consent shall constitute an Event of Default and entitle Landlord to
recover possession of the Premises in accordance with applicable law.

29.      Limitation of Liability

         Tenant agrees to look only to the equity of Landlord in the Premises
and not to Landlord personally with respect to any obligations or payments due
or which may become due from Landlord hereunder, and no other property or assets
of Landlord or any partner, joint venturer, officer, director, shareholder,
agent, or employee of Landlord, disclosed or undisclosed, shall be subject to
levy, execution or other enforcement procedure for the satisfaction of Tenant's
claims under or with


                                       16
<PAGE>

respect to this Lease, and no partner, officer, director, agent or employee of
Landlord shall be personally liable in any manner or to any extent under or in
connection with this Lease. If at any time the holder of Landlord's interest
hereunder is a partnership or joint venture, a deficit in the capital account of
any partner or joint venturer shall not be considered an asset of such
partnership or joint venture.

30.      Brokerage

         Tenant and Landlord each represents and warrants to the other that it
has dealt with no broker, agent or other person in connection with this
transaction and that no broker, agent or other person brought about this
transaction, other than the brokers set forth in the Basic Lease Information
attached hereto and Tenant and Landlord agree to indemnify and hold the other
harmless from and against any claims by any other broker, agent or other person
claiming a commission or other form of compensation by virtue of having dealt
with the indemnifying party with regard to this leasing transaction. The
provisions of this paragraph shall survive the expiration or termination of this
Lease.

31.      Invalidity of Provision

         If any term, provision, covenant or condition of this Lease or the
application thereof to any person or circumstance shall, to any extent, be
invalid or unenforceable, the remainder of this Lease or the application of such
term, provision, covenant or condition to persons or circumstances other than
those as to which it is held invalid or unenforceable shall not be affected
thereby and each term, provision, covenant or condition of this Lease shall be
valid and be enforceable to the fullest extent permitted by law. This Lease
shall be construed in accordance with the laws of the State of California.

32.      Time of Essence

         It is understood and agreed between the parties that time is of the
essence of all the terms, provisions, covenants and conditions of this Lease.

33.      Entire Agreement

         This Lease contains the entire agreement between the parties hereto and
all previous negotiations leading thereto, and it may be modified only by an
agreement in writing signed by Landlord and Tenant. No surrender of the Premises
shall be valid unless accepted by Landlord in writing. Tenant acknowledges and
agrees that Tenant has not relied upon any statement, representation, prior
written or prior or contemporaneous oral promises, agreements or warranties
except such as are expressed herein.

         IN WITNESS WHEREOF, the parties hereto have executed this Lease as of
the date first above written.

                                    SUBLEASE

         THIS SUBLEASE made as of the 13th day of July, 1999 between Wolf
Shevack, Inc. d/b/a Partners & Shevack, a New York corporation, having an office
at 101 West 40th Street, New York, New York 10018 ("Landlord"), and Linkshare
Corporation, a Delaware Corporation, having an office at 215 Park Avenue South,
New York, New York 10003, ("Tenant").

                                   WITNESSETH

         1. Landlord hereby leases to Tenant and Tenant hereby hires from
Landlord the entire rentable portion of the eighth floor (the "Demised
Premises"), in the building known as 215 Park Avenue South, New York, New York
10003 (the "Building"), for a term (the "Term") to commence on July 1, 1999,
subject to obtaining the consent of the Prime Landlord pursuant to Article 16,
and to end on December 30, 2006 (the "Expiration Date") unless sooner terminated
as hereinafter provided at an annual base rental rate ("Fixed Rent") of Three
Hundred Ninety Thousand ($390,000.00) Dollars, Thirty-Two Thousand Five Hundred
($32,500.00) Dollars per month, from the Commencement Date to December 31, 2002,
and Four Hundred Twenty Thousand ($420,000.00) Dollars, Thirty Five Thousand
($35,000.00) Dollars per month, from January 1, 2003 to December 30, 2006. If
the Commencement Date shall occur on other than the first day of a month rent
for that month shall be prorated. The Fixed Rent shall be paid in equal
consecutive monthly installments as set forth above in advance on the first day
of each calendar month during the Term, at Landlord's office hereinabove set
forth or at such other place designated in writing by Landlord. The Fixed Rent
is exclusive of electrical service charges which shall be provided by sub-meter.
Simultaneously with the execution of this Sublease, Tenant has paid to Landlord
the first monthly installment of Fixed Rent, receipt of which, subject to
collection, is hereby acknowledged. Notwithstanding the foregoing if the Tenant
is not in material default of its obligations hereunder beyond applicable notice
and grace periods, it shall be entitled to a rental abatement of Fixed Rental
from the Commencement Date until November 30, 1999.

         2. (a) This Sublease is a sublease with respect to the Demised Premises
and is subject and subordinate to all of the terms, covenants and conditions of
that certain Agreement of Lease ("Prime Lease") made as of October 8, 1998
between 215 Park Avenue South Associates L.P. as Landlord ("Prime Landlord") and
Landlord, as tenant, a copy of which has been provided to Tenant, and which
Tenant acknowledges receipt of. Except as specifically provided in, and to the
extent not inconsistent with, the provisions of this Sublease, all of the terms,
covenants and conditions of the Prime Lease, except Articles 24, 32, 42, 43, 45,
and 48 thereof, shall be deemed incorporated herein. Notwithstanding the
foregoing the following Articles shall be incorporated as modified:

                  Article 49(A), Paragraph (ii) and all references to the ninth
                  floor are deleted.
                  Article 50(A)(3) - The multiplication factor shall be 15,000.
                  Article 51(A)(2) - The percentage shall be 5.17 percent and
                  the base year shall be the New York City 1999/2000 Tax Year.


                                       21
<PAGE>

                  Article 52(A)(vii) - The Tenant's share shall be 5.17 percent.

         As used in the Prime Lease, the term "Landlord" shall refer to Landlord
hereunder and the term "Tenant" shall refer to Tenant hereunder. Landlord
represents to Tenant that (i) the Prime Lease is in full force and effect and
has not been amended; (ii) the redacted copy of the Prime Lease presented to the
Tenant is a true copy of the original, except for the deleted portions; (iii) to
the best of Landlord's knowledge, neither Landlord or Tenant is in default under
the Prime Lease, and no condition exists to which with the giving of notice or
the passage of time, or both, would constitute a default under the Prime Lease;
and (iv) to the best of Landlord's knowledge, there are no New York City
Building Department violations or conditions which would give rise with the
passage of time to become such violations, encumbrances or liens affecting the
Demised Premises.

         (b) Tenant acknowledges that it has read and examined the Prime Lease
as redacted and is fully familiar with all of the terms, covenants and
conditions on the tenant's part to be performed thereunder. Tenant covenants and
agrees that, except for the payment of Fixed Rent and Additional Rent (as such
terms are defined in the Prime Lease), it will perform and observe all of the
terms, covenants and conditions contained in the redacted Prime Lease to be
performed and observed on the part of the "Tenant" thereunder during the term of
this Sublease insofar as they relate to the Demised Premises, other than the
redacted portions hereof, and any default by Tenant in the performance or
observance of such terms, covenants and conditions of the Prime Lease shall be
deemed a default under this Sublease. Tenant will and does hereby indemnify and
hold Landlord harmless from and against any and all actions, claims, demands,
damages, liabilities and expenses (including, without limitation, reasonable
attorney's fees) based upon, or incurred on account of, any violation of such
terms, covenants and conditions caused suffered or permitted by Tenant, its
agents, servants, employees or invitees. Landlord hereby agrees to pay the Fixed
Rent and Additional Rent, if any, when due and otherwise comply with the
provisions of the Prime Lease which are not the Tenant's obligations under this
Sublease. A failure of the Landlord hereunder to make any payment of fixed rent
or additional rent due the Prime Landlord under the Prime Lease shall be deemed
a breach hereunder, and the Tenant shall be allowed to make the appropriate
payments to the Prime Landlord. If any payment made to the Prime Landlord by
Tenant exceeds the payments due hereunder, Landlord shall reimburse Tenant
within ten (10) business days of the demand for payment by Tenant. Tenant shall
be further entitled to cure Landlord's non-monetary defaults under the Prime
Lease. Landlord hereby agrees to indemnify Tenant against all cost, expenses and
claims, including reasonable attorneys fees, with reference to any claims by the
Manhattan Studio Architect & Design, P.C. with references to professional
services provided by them to Landlord regarding either the eighth or ninth
floors of the Building.

         3. Tenant shall use and occupy the Demised Premises for general
executive and administrative offices in connection with Tenant's business and
for no other purpose.

         4. (a) Simultaneously with the execution of this Sublease, Tenant shall
deposit with Landlord the sum of $135,000.00, as security for the full and
faithful performance and


                                       22
<PAGE>

observance by Tenant of the terms, provisions, covenants and conditions of this
Sublease on Tenant's part to be performed and observed. In the event the Tenant
is not in default of any of its obligations hereunder on January 1, 2003, after
any applicable notice and cure periods, Tenant shall be entitled to refund of
$65,000.00 of the security deposit, and one half of the accrued interest, or to
replace the existing letter of credit, as hereinafter provided, with a letter of
credit in the sum of $70,000.00.

                  (b) Landlord shall deposit such funds in an interest bearing
account for the benefit of Tenant, with accrued interest to be retained with the
security deposit for the benefit of the Tenant, provided however Landlord shall
be entitled to retain one (1%) one percent of the security deposit annually as
an administrative fee.

                  (c) In lieu of maintaining a cash deposit as previously
described Tenant may establish and maintain during the term hereof an clean,
unconditional, irrevocable letter of credit in the amount specified. The letter
of credit shall be issued by a New York Clearing House Bank and shall be in a
form reasonably acceptable to Landlord for a period extending thirty (30) days
after the conclusion of the term hereof. Such letter of credit shall provide,
among other provisions, that it shall be drawable, either in partial draws or in
a single draw for the full amount, at the same time(s) and the same amount(s) as
the cash deposit might be applied by Landlord pursuant to the provisions of this
Article. If at any time the total of the undrawn amount(s) of the letter of
credit and any cash deposits then held by Landlord shall be less than the amount
specified in Article 4 (a) hereof, then Tenant shall immediately deposit with
the Landlord an additional letter of credit or an additional cash deposit equal
to such deficiency. Said letter shall be for successive terms of not less than
one year and shall be automatically be renewed unless the issuing bank shall
give Landlord notice thereof not less than thirty (30) days before the
expiration of the then current term. In the event Landlord receives notice of
non-renewal of the letter of credit it shall be entitled to draw and retain as a
cash security deposit the entire then current balance.

                  (d) Landlord may use, apply or retain the whole or any part of
the security deposit to the extent required for the payment of any Fixed Rent or
any other sum as to which Tenant is in default, after any applicable notice and
cure periods, or for any sum which Landlord may expend or may be required to
expend by reason of Tenant's default in respect of any of the terms, provisions,
covenants and conditions of this Sublease, including, but not limited to, any
damages or deficiency in the reletting of the Demised Premises, whether such
damages or deficiency accrued before or after summary proceedings or other
re-entry of Landlord. In the event that Tenant shall fully and faithfully comply
with all of the terms, provisions, covenants and conditions of this Sublease,
the security deposit, or so much thereof as shall not have been applied by
Landlord as aforesaid, shall be returned to Tenant promptly after the Expiration
Date (or earlier termination date) and after delivery of entire possession of
the Demised Premises to Landlord. In the event of an assignment by Landlord of
its interest under the Prime Lease, Landlord shall have the right to transfer
the security deposit to the assignee and Landlord shall thereupon be released by
Tenant from all liability for the return of such security deposit provided that
the Assignee shall assume the obligation to maintain the Security Deposit in
accordance with


                                       23
<PAGE>

the terms and conditions of this Sublease. In such event, Tenant shall look
solely to the new landlord or any subsequent transferee for the return of said
security deposit. Tenant further covenants that it will not assign or encumber
or attempt to assign or encumber the security deposit and that neither Landlord
nor it successors or assigns shall be bound by any such assignment, encumbrance,
attempted assignment or attempted encumbrance.

         5. In the event that Tenant shall default in the full performance of
any of the terms, provisions, covenants and conditions on its part to be
performed under this Sublease following the notice and any applicable grace
procedures in the Prime Lease, then Landlord shall have the same rights and
remedies with respect to such default as are given to the Prime Landlord under
the Prime Lease with respect to defaults by the "Tenant" under the Prime Lease,
all with the same force and effect as though the provisions of the Prime Lease
with respect to defaults and the rights and remedies under the Prime Lease in
the event thereof were set forth at length herein. Notwithstanding anything to
the contrary contained in the Prime Lease and without limiting the generality of
the preceding sentence, if Tenant fails to surrender possession of the Demised
Premises on the Expiration Date or such earlier date as this Lease may be
terminated, (i) Landlord shall be entitled to all of the rights and remedies
which are available to a landlord against a tenant holding over after the
expiration of a term and to such other rights and remedies as may be provided
for in this Sublease, the Prime Lease, at law or in equity and (ii) Tenant, at
Landlord's option, shall be deemed to be occupying the Demised Premises as a
tenant from month to month, at a monthly rental equal to the greater of (a) two
times (2x) the Fixed Rent and Additional Rent payable during the last full
calendar month immediately preceding the expiration or termination of this
Sublease or (b) all loss, cost, liability and expense (including actual
attorneys fees and disbursements) suffered or incurred by Landlord, as a result
of Tenant's occupancy of the Demised Premises after the Expiration Date and
including, without limitation, damages or costs of any kind paid or payable by
Landlord to Prime Landlord or any third party, with respect to the entire
premises of which the Demised Premises are a part but excluding any loss caused
solely by the holding over of any other subtenant or assignee in the balance of
Landlord's space.

         6. (a) Tenant shall have and enjoy the same rights to have facilities
and services furnished by Prime Landlord as Landlord possesses under the
provisions of the Prime Lease. Landlord agrees that if at any time during the
Term such facilities or services are not furnished or are improperly furnished
to Tenant, then, upon receipt of written notice from Tenant specifying such
failure, Landlord shall use its reasonable efforts to cause such facilities
and/or services to be resumed or properly furnished or performed by Prime
Landlord insofar as the same apply to or affect the Demised Premises, provided
that Prime Landlord's failure to furnish and/or perform such facilities or
service does not result from anything done or permitted to be done by Tenant
which would excuse Prime Landlord from the furnishing or performance thereof. If
Landlord shall commence litigation in order to obtain any such work, facilities,
services or duties for Tenant, which litigation Tenant may join, and whether or
not it so joins, Tenant shall pay all reasonable costs and expenses (including
attorney's fees) incurred in connection therewith. No such litigation shall be
commenced without Tenant's prior written approval. The failure of Landlord to
cause any such facilities and/or services to be resumed or properly furnished or


                                       24
<PAGE>

performed shall in no event (unless Prime Landlord's failure is a result of
Landlord's default under the Prime Lease) excuse Tenant from the full
performance of all of the terms, provisions, covenants and conditions of this
Lease on the part of Tenant to be performed, including, without limitation,
Tenant's obligation to pay Fixed Rent and Additional Rent. Notwithstanding the
foregoing, if Landlord is entitled to an abatement of rent from the Prime
Landlord due to the failure of the Prime Landlord supply facilities and/or
services, then Tenant shall be entitled to a prorata abatement of Fixed and
Additional Rent due hereunder.

                  (b) Notwithstanding anything, in the Prime Lease or this
Sublease to the contrary, Tenant covenants and agrees that Landlord shall not be
obligated to perform any services of any nature whatsoever (including, without
limitation, the furnishing of heat, electrical energy, water, air cooling or air
conditioning, elevator service, window washing or rubbish removal services), nor
