                                    SUMMARY

    This summary may not contain all of the information that is important to
you. You should read the entire prospectus, including "Risk Factors" and the
financial statements and related notes, before deciding to invest in our common
stock.

                                  Our Company

    We are a leading Internet-based local merchant network interconnecting
consumers, merchants and national advertisers. We connect consumers searching
for specific products and services with the merchants that provide them. We
offer our users local information about people and businesses across the United
States, including listings of over 96 million individuals, 12 million
businesses and four million e-mail addresses. Our online network gives local
merchants a fast, easy, cost-effective way to get their businesses represented
online and facilitates commerce by connecting them with consumers. We provide
an effective online lead generation engine for these local merchants and for
national advertisers that reaches consumers motivated to buy products and
services in specific geographic locations.

    We entered into a strategic relationship with CBS in June 1999 under which
CBS became a minority stockholder of Switchboard in exchange for $95.0 million
in advertising and promotion to be provided to us through June 2006 across all
CBS media properties, including television, radio and outdoor advertising, and
$5.0 million in cash. We also received a license from CBS to use the "CBS" and
CBS "eye" device trademarks. Our relationship with CBS positions us to build
our brand, attract consumers and increase the credibility of our service with
local merchants. In addition to our CBS relationship, we reach a large base of
consumers and local merchants through our relationships with financial
services, telecommunications and newspaper companies and Internet destinations.
Through these relationships, we add new merchants to our network and increase
the number of consumers using our Web site.

                             Our Market Opportunity

    The number of Internet users worldwide is projected to increase to 500
million by the end of 2003 from approximately 195 million in 1999, according to
International Data Corporation. IDC projects total business-to-consumer online
commerce will increase to $178 billion in 2003 from approximately $31 billion
in 1999. Forrester Research estimates that online advertising in the United
States will increase to $17.2 billion in 2003 from approximately $1.3 billion
in 1998.

    Historically, consumers have used printed materials such as yellow pages
directories and maps to identify and seek out businesses that provide specific
products and services in their area. These sources, however, typically cover
narrowly defined geographic areas and some are updated only once per year.
Recently, consumers have turned to online directories as an alternative source
of local information. Consumers, however, continue to encounter difficulties
obtaining the relevant information they seek because of the volume and
fragmented nature of online local information.

    At the same time, local merchants are increasingly recognizing the need to
establish an online presence to remain competitive. According to Forrester
Research, the aggregate number of businesses with 100 or fewer employees with a
Web presence is projected to increase to approximately 4.2 million by the end
of 2003 from approximately 2.1 million in 1999. Forrester Research also
predicts local online commerce will increase to $6.1 billion in 2003 from
approximately $680 million in 1998. Creating an online presence, however, is
often a difficult and costly task for small businesses. Local merchants may
struggle with the financial, technical and administrative challenges associated
with creating, maintaining and promoting an effective Web site.

                                  Our Solution

    We have created a single online destination, Switchboard.com, that
satisfies consumers' need for easily accessible detailed local information and
merchants' need to establish and maintain an online presence. Switchboard.com
attracted approximately 2.5 million unique visitors in December 1999 according
to Media Metrix. Our Web sites have over 2.4 million registered users, and our
users viewed over 50 million pages in December 1999.

    We provide the following benefits to consumers:

    Extensive information base. We provide our users with links to a growing
base of over 350,000 business Web sites. This provides our users with a
powerful tool to research and compare competitive products and services and to
ultimately conduct business, both online and offline.

    Powerful search capability. Our proprietary directory architecture combined
with our intuitive screen display allows search results to be delivered quickly
with fewer page views. Search results can be organized alphabetically or by
geographic proximity.

    Integrated maps and driving directions. Our Maps On Us maps and driving
directions technology is fully integrated with our directory services. Once a
consumer identifies a desired address, Maps On Us allows the consumer to plot
the most effective route to that destination, including intermediate stopping
points.

    We also provide the following benefits to merchants and national
advertisers:

    Fast cost-effective Web presence. We quickly and cost-effectively develop
and deploy multi-page Web sites for local merchants while eliminating the
associated technical, administrative and financial challenges.

    Participation in a leading online local merchant network. We provide local
merchants with access to our nationally recognized, highly trafficked merchant
network, Switchboard.com, which provides merchants with exposure to consumers
beyond their immediate local area.

    Lead generation. Our online network attracts self-qualified consumers and
helps to connect them with our merchant customers.

    Customized advertising options for national advertisers. We offer national
advertisers a wide range of customized advertising options designed to generate
leads at the local or national level.

                                  Our Strategy

    We intend to be the leading Internet-based local merchant network by:

  .   building our brand;

  .   expanding our merchant aggregation programs;

  .   creating specialized directories for targeted groups of consumers who
      share a common interest;

  .   extending our technology leadership; and

  .   expanding our operations internationally.

                             Our Operating History

    We were incorporated in Delaware in April 1996 as a subsidiary of Banyan
Systems Incorporated, or Banyan Worldwide. Prior to this offering, we were a
majority owned subsidiary of Banyan Worldwide. We have incurred significant net
losses in each fiscal quarter since our inception and expect to continue to
incur net losses and negative cash flows during 2000.

                                  RISK FACTORS

    This offering involves a high degree of risk. You should consider carefully
the risks and uncertainties described below and the other information in this
prospectus, including the financial statements and related notes, before
deciding to invest in shares of our common stock. The risks and uncertainties
described below may not be the only risks that we face. If any of these risks
or uncertainties actually occurs, our business, financial condition and results
of operations would likely suffer. In that event, the market price of our
common stock could decline and you could lose all or part of the money you paid
to buy our common stock.

                       Risks Related to Our Business

Our limited operating history and our lack of any operating history as a stand-
alone company makes it difficult to evaluate our business and our ability to
address the risks and uncertainties that we face

    We have only a limited operating history on which you can evaluate our
business and prospects. In addition, since commencing operations in 1996, we
have been a subsidiary of Banyan Worldwide. Consequently, we have no operating
history as a stand-alone company and no experience in addressing various
business challenges without the support of a corporate parent. We may not
successfully address the risks and uncertainties which confront stand-alone
companies, particularly companies in new and rapidly evolving markets like
ours.

We have a history of incurring net losses, we expect our net losses to continue
as a result of planned increases in operating expenses and we may never
achieve profitability

    We have incurred significant net losses in each fiscal quarter since our
inception. From inception to December 31, 1999, we have incurred net losses
totaling $21.0 million. We expect to continue to incur net losses and negative
cash flows throughout 2000 because we intend to increase operating expenses to
develop the Switchboard brand through marketing, promotion and enhancement and
to expand our services. As a result of this expected increase in operating
expenses, we will need to generate significant additional revenue to achieve
profitability. It is possible that we may never achieve profitability and, even
if we do achieve profitability, we may not sustain or increase profitability on
a quarterly or annual basis in the future. If we do not achieve sustained
profitability, we will be unable to continue our operations.

Our quarterly results of operations are likely to fluctuate, and as a result,
we may fail to meet the expectations of our investors and securities analysts,
which may cause the price of our common stock to decline

    Our quarterly revenue and results of operations are volatile and are
particularly difficult to predict. Our quarterly results of operations have
fluctuated significantly in the past and are likely to fluctuate significantly
from quarter to quarter in the future. We do not believe that period-to-period
comparisons of our results of operations are necessarily meaningful and you
should not rely upon these comparisons as indicators of our future performance.

    Factors that may cause our results of operations to fluctuate include:

  .   the addition or loss of relationships with third parties that are our
      source of new merchants or that license our services for use on their
      own Web sites;

  .   our ability to attract and retain consumers, local merchants and
      national advertisers to our Web site;

  .   the amount and timing of expenditures for expansion of our operations,
      including the hiring of new employees, capital expenditures and related
      costs;

  .   technical difficulties or failures affecting our systems or the
      Internet in general;

  .   the cost of acquiring, and the availability of, content, including
      directory information and maps; and

  .   the fact that our expenses are partially based on our expectations
      regarding future revenue and are largely fixed in nature, particularly
      in the short term.

As a result of these factors, results in any future quarter may be below the
expectations of securities analysts or investors. If so, the market price of
our common stock may decline significantly.

                                       8

Our business model will fail if our operations are unable to generate
sufficient revenue to cover the cost of the content and services we provide to
consumers at no charge

    Our model for conducting business is unproven and may not succeed. Because
we provide our services to consumers at no charge, our business model depends
upon our ability to generate revenue from:

  .   Internet advertising and sponsorships fees;

  .   Web site design, construction, hosting and enhancement services
      provided to local merchants; and

  .   licensing of our services to third parties for use on their Web sites.

We may not be able to generate sufficient revenue to cover the cost of the
content and services that we provide to consumers at no charge.

We need to develop the Switchboard brand to attract users to our Web site,
which will be costly and may not generate revenue

    Building recognition of our brand is critical to attracting and expanding
our user base. We are pursuing an aggressive brand-building strategy and, if
this strategy is unsuccessful, we may never cover our costs. In addition to the
advertising and promotion available to us from CBS, we intend to incur
significant additional expenditures for future advertising and promotional
programs and activities. We may find it necessary to accelerate expenditures on
our sales and marketing efforts or otherwise increase our financial commitment
to creating and maintaining brand awareness among potential users. In addition,
even if awareness of our brand increases, the number of new users of our Web
site may not increase or result in increased revenue.

If our relationship with CBS does not for any reason result in positive
association with the Switchboard brand, our brand could be damaged

    We use the "CBS" trademark and "eye" device under a license agreement with
CBS, which we entered into in June 1999. Therefore, we have limited experience
integrating CBS's trademarks into our effort to build our brand. While CBS's
trademarks are well-recognized, we cannot be certain that our use of these
trademarks will increase awareness of or preference for the Switchboard brand
due to our limited experience in using them and the potential for confusion
between CBS's businesses and our business. In addition, CBS licenses the use of
its name and trademarks to other companies, some of whom have unproven business
plans in competitive markets. If CBS or any of these companies experiences
business difficulties or conducts activities which damage the CBS brand, the
Switchboard brand could be damaged.

If we do not enter into and maintain relationships with merchant aggregators,
our ability to attract new local merchant customers and to deliver services to
current local merchant customers would be impeded

    For our business to be successful, we must expand our merchant aggregation
program and generate significant revenue from that program. The success of our
merchant aggregation program depends in substantial part upon our ability to
access a broad base of local merchants. The local merchant base is highly
fragmented. Local merchants are difficult to contact efficiently and cost-
effectively. Consequently, we depend on merchant aggregators, like Discover
Financial Services, Inc., a subsidiary of Morgan Stanley Dean Witter & Co., to
provide us with local merchant contacts and to provide billing and other
administrative services relating to our local merchant services. The
termination of our strategic relationship with Discover or other merchant
aggregators would significantly impair our ability to attract potential local
merchant customers and deliver our local merchant services to our current
customers. Furthermore, we cannot be certain that we will be able to develop or
maintain relationships with new merchant aggregators on terms acceptable to us
or at all.

If we cannot demonstrate the value of our local merchant services, local
merchant customers may stop using our services, which could reduce our revenue

    We may be unable to demonstrate to our local merchant customers the value
of our local merchant services. If local merchants cancel our services, which
are generally provided on a month-to-month basis, our

                                       9
<PAGE>

revenue could decline and we may need to incur additional expenditures to
obtain new local merchant customers. We do not presently provide our local
merchant customers with data demonstrating the number of leads generated by our
local merchant services. Other forms of advertising available to local
merchants provide local merchants with tangible evidence, such as a coupon, of
a lead resulting from their advertising efforts. Regardless of whether our
local merchant services effectively produce leads, our local merchant customers
may not know the source of the leads and may cancel our local merchant
services.

We depend on strategic alliances with third parties to grow our business and
our business may not grow if the strategic alliances upon which we depend fail
to produce the expected benefits or are terminated

    Our business depends upon our ability to maintain and benefit from our
existing strategic alliances and to establish additional strategic alliances.
In addition to our relationship with CBS and our existing relationships with
merchant aggregators, we have entered into relationships with syndication
customers and third-party content providers. These parties may not perform
their contractual obligations to us and, if they do not, we may not be able to
require them to do so. Some of our strategic relationships may be terminated by
either party on short notice.

    Our strategic relationships are in early stages of development. These
relationships may not provide us benefits that outweigh the costs of the
relationships. If any strategic ally demands a greater portion of revenue or
requires us to make payments for access to its Web site, we may need to
terminate or refuse to renew that relationship, even if it had been previously
profitable or otherwise beneficial. In addition, if we lose a significant
strategic ally, we may be unable to replace that relationship with other
strategic relationships with comparable revenue potential, content or user
demographics.

The attractiveness of our services would diminish if we are not able to license
accurate database information from third-party content providers

    We principally rely upon single third-party sources to provide us with our
business and residential listings data, e-mail data and mapping data. The loss
of any one of these sources or the inability of any of these sources to collect
their data could significantly and adversely affect our ability to provide
information to consumers. Although other sources of database information exist,
we may not be able to integrate data from these sources into our database
systems in a timely, cost-effective manner or without an inordinate expenditure
of internal engineering resources. Other sources of data may not be offered on
terms acceptable to us. Moreover, the rapid consolidation being experienced by
Internet-related businesses could reduce the number of content providers with
which we could form relationships.

    We typically license information under arrangements that require us to pay
royalties or other fees for the use of the content. In the future, some of our
content providers may demand a greater portion of advertising revenue or
increase the fees that they charge us for their content. If we fail to enter
into and maintain satisfactory arrangements with existing or substitute content
providers, we may be unable to continue to provide our services.

    The success of our business depends on the quality of our services and the
quality is substantially dependent on the accuracy of data we license from
third parties. Any failure to maintain accurate data could impair the
reputation of our brand and our services, reduce the volume of users attracted
to our Web site and diminish the attractiveness of our service offerings to our
strategic partners, advertisers and content providers.

If we do not attract a large number of users to our Web site who have
demographic characteristics that are attractive to advertisers, the advertising
revenue on which we rely will substantially decline

    We have derived a substantial portion of our revenue from the sale of
advertisements and sponsorships. If we are unable to remain an attractive
medium for advertising, our revenue will substantially decline. Our ability to
remain an attractive medium for advertising will depend upon a number of
factors, including, the acceptance of our services by a large number of users
who have demographic characteristics that are attractive to advertisers.

                                       10
<PAGE>

Our agreements to sell advertisements expose us to competitive pricing
pressures and may require us to provide advertising at no charge if we do not
meet minimum guarantees

    We typically sell advertisements under agreements with terms of less than
six months. These short-term agreements expose us to competitive pricing
pressures and potentially severe fluctuations in our results of operations. In
addition, these agreements often contain guarantees by us of a minimum number
of impressions or click throughs by Web users. If we fail to meet these
guarantees, we are required to provide our advertising customers with
advertising at no charge until the guarantees are met.

We rely on a small number of advertising and syndication customers, the loss of
whom may substantially reduce our revenue

    We derive a substantial portion of our revenue from a small number of
advertising and syndication customers. For the year ended December 31, 1999,
revenue derived from our top ten customers accounted for approximately 64.3% of
our total revenue. Consequently, our revenue may substantially decline if we
lose any of these customers. We anticipate that our future results of
operations will continue to depend to a significant extent upon revenue from a
small number of customers. In addition, we anticipate that the identity of
those customers will change over time.

The growth of our revenue will suffer if we do not increase the number and
productivity of our sales personnel, many of whom have only recently joined us

    Our ability to generate revenue through the sale of advertising would be
adversely affected if we do not develop and maintain a productive sales force.
Our sales group consisted of only seven members as of December 31, 1999. We
need to increase the size of our sales force to accelerate our revenue growth.
Our Director of National Ad Sales joined us in April 1999, and four other
members of our sales group joined us since October 1999. Typically new sales
personnel require six to twelve months to become productive. If our sales force
does not increase its productivity, the growth of our revenue may be impeded.

If we do not introduce new or enhanced services for our Web site, we may be
unable to attract and retain consumers and local merchants, which would
significantly impede our ability to generate revenue

    We need to introduce new or enhanced services to attract and retain local
merchants to our services, attract more consumers to our Web site and respond
to competition. If we are not able to introduce new or enhanced services, we
may lose existing local merchants and consumers or fail to attract new ones,
which would significantly impede our revenue growth. Any new product or service
introduction not favorably received could damage our reputation and our brand.
We may also experience difficulties that could delay or prevent us from
introducing new services.

Our senior management has limited experience working together as a team and any
difficulties they encounter in integrating successfully may interfere with the
operation of our business

    Our future success depends to a significant extent on the continued
services and effective working relationships of our senior management and other
key personnel, including Douglas Greenlaw, our Chief Executive Officer, and
Dean Polnerow, our founder and President. Mr. Greenlaw joined us in October
1999 and has not previously worked with other members of our senior management
team. Our business will suffer if we lose the services of Mr. Greenlaw, Mr.
Polnerow or other key personnel, or if we are unable to integrate Mr. Greenlaw
successfully into our current senior management team.

If we are not able to attract and retain highly skilled managerial and
technical personnel with Internet experience, we may not be able to implement
successfully our business model

    We believe that our management must be able to act decisively to apply and
adapt our business model in the rapidly changing Internet markets in which we
compete. In addition, we rely upon our technical employees to develop and
maintain much of the technology used to provide our services. Consequently, we
believe that our success depends largely on our ability to attract and retain
highly skilled managerial and technical

                                       11
<PAGE>

personnel. The industry in which we compete has a high level of employee
turnover. We may not be able to hire or retain the necessary personnel to
implement our business strategy. In addition, we may need to pay higher
compensation for employees than we currently expect. Individuals with the
skills we require, particularly with Internet experience, are in very short
supply. Competition to hire from this limited pool is intense.

If we do not improve our management, financial and information systems and
controls, we may fail to properly manage our growth, which would strain our
resources and could impede further growth

    We have significantly expanded our operations and must expand further if we
are to be successful in building our business. Our growth has placed, and will
continue to place, a significant strain on our management, operating and
financial systems, and sales, marketing and administrative resources. If we
cannot manage our expanding operations, we may not be able to continue to grow
or may grow at a slower pace. Furthermore, our operating costs may escalate
faster than we expect. To manage our growth successfully we will need to
improve our management, financial and information systems and controls.

The markets for Internet content, services and advertising are highly
competitive and our failure to compete successfully will limit our ability to
increase or retain our market share

    Our failure to maintain and enhance our competitive position will limit our
ability to increase or maintain our market share, which would seriously harm
our business. We compete in the markets for Internet content, services and
advertising. These markets are new, rapidly evolving and highly competitive. We
expect this competition to intensify in the future. We compete, or expect to
compete, with many providers of Internet content, information services and
products, as well as with traditional media, for audience attention and
advertising and sponsorship expenditures. We license much of our database
content under nonexclusive agreements with third-party providers which are in
the business of licensing their content to many businesses, including our
current and potential competitors. Many of our competitors are substantially
larger than we are and have substantially greater financial, infrastructure and
personnel resources than we have. In addition, many of our competitors have
well established, large and experienced sales and marketing capabilities and
greater name recognition than we have. As a result, our competitors may be in a
stronger position to respond quickly to new or emerging technologies and
changes in customer requirements. They may also develop and promote their
services more effectively than we do. Moreover, barriers to entry are not
significant, and current and new competitors may be able to launch new Web
sites at a relatively low cost. We therefore expect additional competitors to
enter these markets. Some of these new competitors may be traditional media
companies, who are increasingly expanding onto the Internet.

    Many of our current customers have established relationships with our
current and potential competitors. If our competitors develop content that is
superior to ours or that achieves greater market acceptance than ours, we may
not be able to develop alternative content in a timely, cost-effective manner,
or at all, and we may lose market share.

We may not be able to dedicate the substantial resources required to expand,
monitor and maintain our internally developed systems without contracting with
an outside supplier at substantial expense

    We will have to expand and upgrade our technology, transaction-processing
systems and network infrastructure if the volume of traffic on our Web site or
our syndication partners' Web sites increases substantially. We could
experience temporary capacity constraints that may cause unanticipated system
disruptions, slower response times and lower levels of customer service. We may
not be able to project accurately the rate or timing of increases, if any, in
the use of our services or expand and upgrade our systems and infrastructure to
accommodate these increases in a timely manner. Our inability to upgrade and
expand as required could impair the reputation of our brand and our services,
reduce the volume of users able to access our Web site and diminish the
attractiveness of our service offerings to our strategic partners, advertisers
and content providers. Because we developed these systems internally, we must
either dedicate substantial internal resources to monitor, maintain and upgrade
these systems or contract with an outside supplier for these services at
substantial expense.

                                       12

Our internally developed software may contain undetected errors, which could
limit our ability to provide our services and diminish the attractiveness of
our service offerings

    We use internally developed, custom software to provide our services. This
software may contain undetected errors, defects or bugs. Although we have not
suffered significant harm from any errors or defects to date, we may discover
significant errors or defects in the future that we may not be able to fix. For
example, while we have not experienced any operational difficulties relating to
the transition from December 31, 1999 to January 1, 2000, it is possible that
we may in the future experience unexpected date-related processing errors. Our
inability to fix any of those errors could limit our ability to provide our
services, impair the reputation of our brand and our services, reduce the
volume of users who visit our Web site and diminish the attractiveness of our
service offerings to our strategic partners, advertisers and content providers.

We do not have a formal disaster recovery plan, and a disaster that results in
the inability of consumers to visit our site would severely damage our
operations.

    Our ability to generate revenue depends in large part on the number of
users that access our Web site. Our computer and communications hardware is
located at hosting facilities in Waltham, Massachusetts provided by Exodus
Communications, Inc. Our systems and operations could be damaged or interrupted
by fire, flood, power loss, telecommunications failure, Internet breakdown,
break-in, earthquake and similar events. We do not have a formal disaster
recovery plan, and we do not carry business interruption insurance that is
adequate to compensate us for losses that may occur. Any system interruptions
resulting in the complete or partial unavailability or slow or delayed delivery
of our Web site could impair the reputation of our brand and our services,
diminish the attractiveness of our service offerings to our strategic partners,
advertisers and content providers and reduce the volume of users able to access
our Web site. Any volume reductions could harm our ability to satisfy minimum
advertising commitments. In addition, a system interruption may give CBS the
right to suspend or terminate our advertising and promotion agreements and our
license to use the "CBS" trademark and "eye" device.

Our inexperience in doing business in international markets exposes us further
to various risks and may limit the success of any expansion of our business
into international markets

    In September 1999, we entered into an agreement to provide directory
services in Canada. As opportunities arise, we intend to pursue strategic
initiatives internationally. We will face additional risks related to doing
business in international markets, such as changes in regulatory requirements,
difficulties in protecting and enforcing our intellectual property, tariffs and
other trade barriers, fluctuations in currency exchange rates and adverse tax
consequences. Our inexperience in doing business in international markets
exposes us further to these risks and may make it more difficult for us to
staff and manage any foreign operations. In addition our services may not be
perceived to be valuable because of different consumer preferences and
requirements in specific international markets. The effects of one or more of
these factors may limit the success of any expansion of our business into
international markets.

We may need additional capital, which may not be available to us and which, if
available, may dilute your ownership interest in us

    We may need to raise additional funds through public or private equity or
debt financings to:

  .   expand our sales and marketing operations to increase their
      productivity;

  .   develop new technology and upgrade current technology and data network
      infrastructure to comply with rapidly evolving industry standards;

  .   develop new and expand current content and services to attract and
      retain consumers and local merchants;

  .   pursue acquisitions or expansion opportunities in our consolidating
      markets; or

  .   address additional general corporate needs.

    If we cannot obtain any needed financing on acceptable terms, we may be
forced to curtail some or all of these activities. As a result we could grow
more slowly or stop growing. Any additional capital raised through the sale of
equity may dilute your ownership interest in us and may be on terms that are
unfavorable to holders of our common stock.

We have no experience acquiring companies, and any acquisitions we undertake
could limit our ability to manage and maintain our business, result in adverse
accounting treatment and be difficult to integrate into our business

    We have no experience in acquiring businesses and have very limited
experience in acquiring complementary technologies. In the future we may
undertake acquisitions. Acquisitions, in general, involve numerous risks,
including:

  .   diversion of our management's attention;

  .   amortization of substantial goodwill, adversely affecting our reported
      results of operations;

  .   inability to retain the management, key personnel and other employees
      of the acquired business;

  .   inability to assimilate the operations, product, technologies and
      information systems of the acquired business with our business; and

  .   inability to retain the acquired company's customers, affiliates,
      content providers and advertisers.

If we are unable to adequately protect our intellectual property rights, our
technology and information may be used by others to compete against us

    We depend upon our internally developed and other proprietary technology.
If we do not effectively protect our proprietary technology, others may become
able to use it to compete against us. To protect our proprietary rights, we
rely on a combination of copyright and trademark laws, patents, trade secrets,
confidentiality agreements with employees and third parties, and protective
contractual provisions. Despite our efforts to protect our proprietary rights,
unauthorized parties may misappropriate our proprietary technology or obtain
and use information that we regard as proprietary. We may not be able to detect
these or any other unauthorized uses of our intellectual property or take
appropriate steps to enforce our proprietary rights. In addition, others could
independently develop substantially equivalent intellectual property.

If our services infringe on intellectual property rights of others, we may be
required to expend substantial resources to reengineer our services and to
incur substantial costs and damages related to infringement claims

    We are subject to the risk of claims alleging infringement of third-party
proprietary rights. If we are subject to claims of infringement of, or are
infringing on, the rights of third parties, we may not be able to obtain
licenses to use those rights on commercially reasonable terms. In that event,
we may need to undertake substantial reengineering to continue our service
offerings. Any effort to undertake such reengineering might not be successful.
In addition, any claim of infringement could cause us to incur substantial
costs defending against the claim, even if the claim is invalid, and could
distract our management. Furthermore, a party making such a claim could secure
a judgement that requires us to pay substantial damages. A judgment could also
include an injunction or other court order that could prevent us from providing
our services.

        Risks Related to Our Relationships with CBS and Banyan Worldwide

Termination of our agreements with CBS would negatively affect our financial
results

    If our agreements with CBS terminate, our business, particularly our
branding and advertising initiatives, would suffer, which would impede our
revenue growth. If our license agreement terminates, we would lose the right to
use the "CBS" trademark and "eye" device which are very important to our
marketing and brand building activities. Our license agreement with CBS will
expire on June 30, 2009 and CBS is not obligated to

                                       14
<PAGE>

renew it. If our advertising and promotion agreement terminates, we may lose
the unused portion of the $95.0 million of advertising and promotion services
which CBS has agreed to provide us through June 2006. Under specified
circumstances, CBS has the right to suspend or terminate the license agreement
and the advertising and promotion agreement prior to their scheduled
expirations.

CBS's contractual right to require us to remove content from our Web site and
to approve all of our uses of its trademarks may restrict our marketing
activities and business opportunities

    Under our license agreement with CBS, CBS can require us to remove any
content on our Web site which it determines conflicts with, interferes with or
is detrimental to its reputation or business. We are also required to conform
to CBS's guidelines for the use of its trademark. CBS has the right to approve
all materials, such as marketing materials, that include CBS trademarks.
Because of these restrictions we may not be able to perform our desired
marketing activities or include some types of content on our Web site which we
would otherwise decide to include.

CBS does not guarantee the availability of the particular advertising
placements that we desire or access to the type of audiences at which we target
our ads, and therefore our ads may not be effective

    CBS does not guarantee us placement of our ads or the demographic
composition or size of the audience that views our ads. Moreover, CBS provides
its advertising and on-air promotions to us under the same terms as it provides
to its other advertising customers and does not extend us priority in the
placement of our ads. CBS has entered into agreements similar to ours with
other companies, some of whom may be targeting similar audiences for their ads
as we target for ours. We cannot be certain that we will receive the ad
placements we desire, particularly if other advertisers are seeking the same
placements. Even if we do receive our desired ad placements, we cannot be
certain of the demographic composition or size of the audience viewing our ads.
Therefore, the CBS advertising available to us may not be effective.

The combined ownership of Banyan and CBS after the offering will, if Banyan and
CBS act together, permit Banyan and CBS to control matters submitted for
approval of our stockholders which could delay or prevent a change of control
or depress our stock price

    After this offering, Banyan Worldwide will beneficially own approximately
41.3% of our common stock and CBS will beneficially own approximately 34.4% of
our common stock. Acting together, Banyan Worldwide and CBS will be able to
control, and acting alone each of Banyan Worldwide and CBS will be able to
substantially influence, all matters submitted to our stockholders for approval
and our management and affairs, including the election and removal of directors
and any merger, consolidation or sale of all or substantially all of our
assets. Other than with respect to the election of directors, Banyan Worldwide
and CBS do not have an agreement to vote in concert. This control could have
the effect of delaying or preventing a change of control of Switchboard that
other stockholders may believe would result in a premium or better management.
In addition, this control could depress our stock price because purchasers will
not be able to acquire a controlling interest in us. These risks would be
exacerbated if a competitor of CBS acquires a 30% voting interest in, or all or
substantially all of the assets of, Banyan Worldwide. In that event, CBS has
the right to purchase all of Banyan Worldwide's shares of our stock.

    Banyan Worldwide has pledged all of our capital stock that it owns as
security for Banyan Worldwide's obligations under its bank credit facility. If
Banyan Worldwide defaults under its bank credit facility, its lender could take
ownership of Banyan Worldwide's capital stock of Switchboard. Moreover, either
or both of Banyan Worldwide and CBS may elect to sell all or a substantial
portion of its capital stock to one or more third parties. In either case, a
third party with whom we have no prior relationship could exercise the same
degree of control over Switchboard as Banyan Worldwide or CBS presently
possess.

                                       15
<PAGE>

So long as Banyan Worldwide and CBS maintain their significant ownership
interest in Switchboard, you will not be able to elect a majority of our board
of directors

    We are a party to a voting agreement with Banyan Worldwide and CBS. Under
that voting agreement Banyan Worldwide has the right to designate a majority of
our board of directors for election. CBS has agreed to vote its shares of our
capital stock for the directors designated by Banyan Worldwide. After this
offering Banyan Worldwide and CBS will together continue to control enough
shares of our capital stock to elect all of our directors. As a result,
directors designated for election by Banyan Worldwide will continue to control
our board of directors and therefore all of our business and affairs. You may
not agree with the management decisions made by our board of directors.

Overlapping management and boards of directors could hinder or delay decisions
regarding significant business matters

    Three of our directors hold positions as officers or directors of Banyan
Worldwide, as described in the following table:

<TABLE>
<CAPTION>
 Name                 Switchboard Position        Banyan Worldwide Position
 ----                 --------------------- ------------------------------------
 <C>                  <C>                   <S>
 William P. Ferry     Chairman of the Board Chairman of the Board, President and
                                             Chief Executive Officer
 Richard M. Spaulding Director              Senior Vice President and Chief
                                            Financial Officer
 Robert M. Wadsworth  Director              Director
</TABLE>

    Serving as a director of Switchboard and either a director or an officer of
Banyan Worldwide could create, or appear to create, potential conflicts of
interest when those directors and officers are faced with decisions that could
have different implications for us than for Banyan Worldwide. These decisions
may relate, for example, to:

  .   potential acquisitions of businesses;

  .   intercompany agreements, such as our services agreement;

  .   the issuance or disposition of securities;

  .   the election of new or additional directors; and

  .   the payment of dividends by us.

These conflicts, or potential conflicts, of interest could hinder or delay our
management's ability to make timely decisions regarding significant matters
relating to our business.

If Banyan Worldwide ceases to provide us with the services and facilities that
it currently provides, we may experience increased costs and disruption of our
operations to replace those services and facilities

    Banyan Worldwide provides us with some of our financial, administrative and
operational services and related support functions. In addition, we occupy our
headquarters in Westboro, Massachusetts under an agreement with Banyan
Worldwide. If Banyan Worldwide ceases or fails to provide these services
satisfactorily or terminates our occupancy, we would be required to perform
these services ourselves or obtain these services from another provider or
locate new facilities. Replacing these services may cause us to incur
additional costs and experience disruption of our operations. We may not be
able to replace these services on commercially reasonable terms or, if we
choose to perform these services ourselves, we may not be able to perform them
adequately.

                         Risks Related to the Internet

If the acceptance and effectiveness of Internet advertising does not become
fully established, the growth of our advertising revenue will suffer

    Our future success depends, in part, on an increase in the use of the
Internet as an advertising medium. We generated 45.1% of our revenue from the
sale of advertisements and sponsorships during the year ended December 31, 1999
and 61.5% in the year ended December 31, 1998. The Internet advertising market
is new and rapidly evolving, and cannot yet be compared with traditional
advertising media to gauge its effectiveness. As a result, demand for and
market acceptance of Internet advertising is uncertain. Many of our current and
potential local merchant customers have little or no experience with Internet
advertising and have allocated only a limited portion of their advertising and
marketing budgets to Internet activities. The adoption of Internet advertising,
particularly by entities that have historically relied upon traditional methods
of advertising and marketing, requires the acceptance of a new way of
advertising and marketing.

    These customers may find Internet advertising to be less effective for
meeting their business needs than traditional methods of advertising and
marketing. In addition, there are software programs that limit or prevent
advertising from being delivered to a user's computer. Widespread adoption of
this software would significantly undermine the commercial viability of
Internet advertising. If the market for Internet advertising fails to develop
or develops more slowly than we expect, our advertising revenue will suffer.

    There are currently no generally accepted standards for the measurement of
the effectiveness of Internet advertising. Standard measurements may need to be
developed to support and promote Internet advertising as a significant
advertising medium. Our advertising customers may challenge or refuse to accept
our, or third-party, measurements of advertisement delivery.

If we are unable to adapt as Internet technologies and customer demands evolve,
our services may not be attractive to consumers, local merchants and
advertisers

    To remain competitive, we must continue to enhance and improve the
responsiveness, functionality and features of our Web site. Our industry has
been characterized by rapid technological change, changes in user and customer
requirements and preferences, frequent new product and service introductions
embodying new technologies. These changes could render our Web site, technology
and systems obsolete. If we do not periodically enhance our existing services,
develop new services and technologies that address sophisticated and varied
consumer needs, respond to technological advances and emerging industry
standards and practices on a timely and cost-effective basis, and address
evolving customer preferences, our services may not be attractive to consumers,
local merchants and advertisers.

If we are sued for content distributed through, or linked to by, our Web site,
we may be required to spend substantial resources to defend ourselves and could
be required to pay monetary damages


    We aggregate and distribute third party data over the Internet. In
addition, third-party Web sites are accessible through our Web site. As a
result, we could be subject to legal claims for defamation, negligence,
intellectual property infringement and product or service liability. Other
claims may be based on errors or false or misleading information provided on
our Web site, such as information deemed to constitute legal, medical,
financial or investment advice. Other claims may be based on links to sexually
explicit Web sites and sexually explicit advertisements. We may need to expend
substantial resources to investigate and defend these claims, regardless of
whether we successfully defend against them. While we carry general business
insurance, the amount of coverage we maintain may not be adequate. In addition,
implementing measures to reduce our exposure to this liability may require us
to spend substantial resources and limit the attractiveness of our content to
users.

                                       17
<PAGE>

We may need to expend significant resources to protect against online security
risks that could result in misappropriation of our proprietary information or
cause interruption in our operations

    Our networks may be vulnerable to unauthorized access, computer viruses and
other disruptive problems. Someone who is able to circumvent security measures
could misappropriate our proprietary information or cause interruptions in our
operations. Internet and online service providers have experienced, and may in
the future experience, interruptions in service as a result of the accidental
or intentional actions of Internet users, current and former employees or
others. We may need to expend significant resources protecting against the
threat of security breaches or alleviating problems caused by breaches.
Eliminating computer viruses and alleviating other security problems may
require interruptions, delays or cessation of service.

We may be sued for disclosing to third parties personal identifying information
without consent

    Individuals whose names, addresses and telephone numbers appear in our
yellow pages and white pages directories have occasionally contacted us because
their phone numbers and addresses were unlisted with the telephone company.
While we have not received any formal legal claims from these individuals, we
may receive claims in the future for which we may be liable. In addition, if we
begin disclosing to third parties personal identifying information about our
users without consent or in violation of our privacy policy, we may face
potential liability for invasion of privacy.

We may become subject to burdensome government regulation and legal
uncertainties which could limit our growth

    Laws and regulations directly applicable to Internet communications,
commerce and advertising are becoming more prevalent. Laws and regulations may
be adopted covering issues such as user privacy, pricing, content, taxation and
quality of products and services. Any new legislation could hinder the growth
in use of the Internet and other online services generally and decrease the
acceptance of the Internet and other online services as media of
communications, commerce and advertising. Various U.S. and foreign governments
might attempt to regulate our transmissions or levy sales or other taxes
relating to our activities. The laws governing the Internet remain largely
unsettled, even in areas where legislation has been enacted. It may take years
to determine whether and how existing laws such as those governing intellectual
property, privacy, libel and taxation apply to the Internet and Internet
advertising services. In addition, the growth and development of the market for
electronic commerce may prompt calls for more stringent consumer protection
laws, both in the United States and abroad, that may impose additional burdens
on companies conducting business over the Internet.

If we cannot protect our domain names, our ability to successfully brand
Switchboard will be impaired

    We currently hold various Web domain names, including Switchboard.com and
MapsOnUs.com. The acquisition and maintenance of domain names generally is
regulated by Internet regulatory bodies. The regulation of domain names in the
United States and in foreign countries is subject to change. Governing bodies
may establish additional top-level domains, appoint additional domain name
registrars or modify the requirements for holding domain names. As a result, we
may be unable to acquire or maintain relevant domain names in all countries in
which we conduct business. This problem may be exacerbated by the length of
time required to expand into any other country and the corresponding
opportunity for others to acquire rights in relevant domain names. Furthermore,
it is unclear whether laws protecting trademarks and similar proprietary rights
will be extended to protect domain names. Therefore, we may be unable to
prevent third parties from acquiring domain names that are similar to, infringe
upon or otherwise decrease the value of our trademarks and other proprietary
rights. We may not be able to successfully carry out our business strategy of
establishing a strong brand for Switchboard if we cannot prevent others from
using similar domain names or trademarks.

                         Risks Related to this Offering

We may become subject to an equity ownership claim from America Online which,
if successful, would result in substantial additional dilution to investors in
this offering

    America Online may assert a claim to acquire 3.75% of our capital stock
under a warrant we issued in 1996. While we believe the warrant has expired
pursuant to its terms, America Online has in the past indicated to us that it
does not agree that the warrant has expired. In March 1999, we resolved a
number of outstanding intercompany balances between ourselves and America
Online, but did not resolve the status of the warrant.

    The disputed warrant, if in effect, would entitle America Online to
purchase 3.75% of our capital stock on the date of exercise, determined on a
fully diluted basis. The latest stated expiration date of the warrant is
November 5, 2000. The per share exercise price of the warrant is equal to $60.0
million divided by the number of fully diluted shares of our capital stock on
the date of exercise.

    Immediately after this offering, the disputed warrant, if in effect, would
entitle America Online to purchase 1,085,751 shares of our common stock at
$2.07 per share. Under our common stock and warrant purchase agreement with
CBS, in the event of a warrant exercise by America Online, we would be required
to issue to CBS for no additional consideration 466,785 additional shares of
our common stock and warrants to purchase 66,683 additional shares of common
stock at an exercise price of $1.00 per share. If we are required to issue
securities to America Online and CBS, the dilution per share to new investors
in this offering, at an assumed initial public offering price of $11.00 per
share, would be increased from $8.54 to $8.98. The amount of dilution could be
greater depending on the number of fully diluted shares of our capital stock
when the America Online warrant is exercised.

    While we intend to vigorously defend against any legal actions America
Online may commence relating to the warrant, there can be no assurance that we
will be successful.

Projections included in this prospectus relating to the growth of the Internet
are based on assumptions that could turn out to be incorrect, and actual
results could be materially different from these projections

    This prospectus contains various third-party data and projections,
including those relating to the number of Internet users and the amount spent
on online commerce and advertising. These data and projections have been
included in studies prepared by independent market research firms, and the
projections are based on surveys, financial reports and models used by these
firms. Actual results or circumstances may be materially different from the
projections. Any difference could reduce our revenue and the growth of our
business. These data and projections are inherently imprecise and investors are
cautioned not to place undue reliance on them.

Our stock price could be volatile, which could result in substantial losses for
investors purchasing shares in this offering and expose us to costly securities
class action litigation

    The trading price of our common stock is likely to be volatile. The stock
market in general, and the market for technology and Internet-related companies
in particular, has experienced extreme volatility. This volatility has often
been unrelated to the operating performance of particular companies. In the
past, securities class action litigation has often been brought against a
company following periods of volatility in the market price of its securities.
Due to the potential volatility of our stock price, we may be the target of
securities litigation which could result in substantial costs and divert
management's attention and resources. We cannot be sure that an active public
market for our common stock will develop or continue after this offering.
Investors may not be able to sell their common stock at or above our initial
public offering price. Prices for the common stock will be determined in the
marketplace and may be influenced by many factors, including variations in our
financial results, changes in earnings estimates by industry research analysts,
the failure or success of our branding initiatives and investors' perceptions
of us.

                                       19
<PAGE>


Our stock price could be adversely affected by future sales of our common
stock, which could limit our ability to raise capital and undertake
acquisitions

    Sales of a substantial number of shares of our common stock in the public
market after this offering could depress the market price of our common stock
and could impair our ability to raise capital and undertake acquisitions
through the issuance of additional equity securities. See "Shares Eligible for
Future Sale."

We have antitakeover defenses that could delay or prevent an acquisition and
could adversely affect the price of our common stock

    Provisions of our certificate of incorporation, our by-laws and Delaware
law could delay, defer or prevent an acquisition or change of control of
Switchboard or otherwise adversely affect the price of our common stock. For
example, our board of directors is classified into three classes, and
stockholders do not have the right to call special meetings of stockholders. In
addition, our certificate of incorporation permits our board to issue shares of
preferred stock without stockholder approval. In addition to delaying or
preventing an acquisition, the issuance of a substantial number of preferred
shares could adversely affect the price of the common stock and may dilute your
ownership interest in us. Please refer to "Description of Capital Stock" for a
more detailed discussion of these provisions.

                           FORWARD-LOOKING STATEMENTS

    This prospectus includes forward-looking statements that are subject to a
number of risks and uncertainties. All statements, other than statements of
historical facts included in this prospectus, regarding our strategy, future
operations, financial position, estimated revenues, projected costs, prospects,
plans and objectives of management are forward-looking statements. When used in
this prospectus, the words "will", "believe", "anticipate", "intend",
"estimate", "expect", "project" and similar expressions are intended to
identify forward-looking statements, although not all forward-looking
statements contain these identifying words. We cannot guarantee future results,
levels of activity, performance or achievements and you should not place undue
reliance on our forward-looking statements. Our forward-looking statements do
not reflect the potential impact of any future acquisitions, mergers,
dispositions, joint ventures or strategic alliances. Our actual results could
differ materially from those anticipated in these forward-looking statements as
a result of various factors, including the risks described in "Risk Factors"
and elsewhere in this prospectus. We do not assume any obligation to update any
of the forward-looking statements we make.

                                USE OF PROCEEDS

    We estimate that the net proceeds from our sale of 5,500,000 shares of
common stock will be approximately $54,265,000, assuming an initial public
offering price of $11.00 per share and after deducting estimated underwriting
discounts and our estimated offering expenses. If the underwriters' over-
allotment option is exercised in full, we estimate that the net proceeds will
be approximately $62,705,000.

    We expect to use the net proceeds of this offering for general corporate
purposes. As of the date of this prospectus, we have not made any specific
expenditure plans with respect to the proceeds of this offering.

    The principal purposes of this offering are to increase our working
capital, create a public market for our common stock, facilitate future access
to the public capital markets and increase our visibility in the marketplace.
Pending use of the net proceeds, we intend to invest these proceeds in short-
term, investment grade, interest-bearing instruments.

                                DIVIDEND POLICY

    We have never declared or paid any dividends on our capital stock. We
intend to retain future earnings, if any, to finance our growth strategy. We do
not anticipate paying cash dividends on our common stock. Payment of future
dividends, if any, will be at the discretion of our board of directors after
taking into account various factors, including:

  .   our financial condition;

  .   our results of operations; and

  .   our current and anticipated cash needs.

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

  .   on an actual basis;

  .   on a pro forma basis to give effect to the automatic conversion of our
      series A, C, and D convertible preferred stock into common stock upon
      the closing of this offering; and

  .   on a pro forma basis as adjusted to reflect the issuance and sale by us
      of 5,500,000 shares of common stock in this offering at an assumed
      initial public offering price of $11.00 per share and after deducting
      the estimated underwriting discounts and estimated offering expenses
      payable by Switchboard.

    The number of shares of common stock outstanding is based on the number of
shares of our common stock outstanding on December 31, 1999 and does not
include:

  .   an aggregate of 2,951,600 shares subject to outstanding options as of
      December 31, 1999, at a weighted average exercise price of $6.23;

  .   an aggregate of 1,751,937 shares subject to outstanding warrants as of
      December 31, 1999 at a weighted average exercise price of $2.71 per
      share, assuming these warrants are all exercised in full; and

  .   an aggregate of 1,793,026 shares reserved for issuance under our 1996
      stock incentive plan, our 1999 stock incentive plan and our 1999
      employee stock purchase plan as of December 31, 1999.

                                    DILUTION

    Our pro forma net tangible book value at December 31, 1999 was
approximately $4,098,000, or $0.22 per share of common stock. Pro forma net
tangible book value per share is determined by dividing the amount of our total
tangible assets less total liabilities by the pro forma number of shares of
stock outstanding at that date, assuming conversion of all outstanding shares
of our series A, C, and D convertible preferred stock into common stock.
Dilution in net tangible book value per share represents the difference between
the amount per share paid by purchasers of shares of common stock in this
offering and the net tangible book value per share of common stock immediately
after the completion of this offering.

    After giving effect to our sale of 5,500,000 shares of common stock in this
offering at an assumed initial public offering price of $11.00 per share and
our receipt of the net proceeds (after deducting the estimated underwriting
discounts and our estimated offering expenses), our pro forma net tangible book
value as of December 31, 1999 would have been approximately $58,364,000, or
$2.46 per share. This represents an immediate increase in pro forma net
tangible book value of $2.24 per share to existing stockholders and an
immediate dilution in pro forma net tangible book value of $8.54 per share to
new investors purchasing shares in this offering. The following table
illustrates this per share dilution:

</TABLE>

    The foregoing table and calculation assumes no exercise of outstanding
stock options and warrants exercisable as of December 31, 1999. As of December
31, 1999, there were:

  .   outstanding stock options to purchase 2,951,600 shares of common stock
      at a weighted average exercise price of $6.23 per share; and

  .   outstanding warrants to purchase 1,751,937 shares of common stock at a
      weighted average exercise price of $2.71 per share.

    To the extent that all of these options and warrants are exercised, pro
forma net tangible book value per share after this offering would be $2.87 and
total dilution per share to new investors would be $8.13.

    If the underwriters' over-allotment option is exercised in full, pro forma
net tangible book value per share after this offering would be $2.72 and total
dilution per share to new investors would be $8.28.

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

    You should read the following discussion together with the financial
statements and related notes appearing elsewhere in this prospectus. This
prospectus contains forward-looking statements that involve risks and
uncertainties. Our actual results may differ materially from those indicated in
forward-looking statements. See "Forward-Looking Statements."

Overview

    Since commencing operations in February 1996, we have derived our revenue
principally from the sale of national advertising. We have also derived revenue
from the licensing of our directory technology content and related services to
third party Web sites, which we refer to as syndication, and from our merchant
aggregation program.

    Our revenue from the sale of advertising consists of banner advertisements,
sponsorships, promotions and other forms of national advertising that are sold
on either a fixed fee, cost per thousand impressions or cost per click basis on
our Web pages. We recognize revenue from national advertising upon delivery of
services. As a result of America Online's termination of its marketing
agreements with us in November and December 1998, we experienced a significant
decrease in the number of page views to our Web site and the associated
advertising revenue. Page views decreased approximately 33% from a pre-
termination high in the third quarter of 1998 to the first quarter of 1999.
Revenue in the first quarter of 1999 was approximately 43% lower than revenue
in the fourth quarter of 1998. Approximately 52% of our total revenue in 1997
and approximately 45% of our total revenue in 1998 was derived from our
agreements with America Online. While growing quarter-to-quarter since December
1998, our quarterly advertising revenue has not yet reached the levels
experienced when our agreements with America Online were in effect. During
1999, approximately 45% of our total revenue was derived from the sale of
national advertising.

    We also derive revenue from various syndication and licensing agreements
with corporate customers which typically involve engineering work to integrate
our products and services with the customer's site and brand, as well as
license fees. We recognize these fees ratably over the term of the contract.
During 1999, approximately 34% of our total revenue was derived from
syndication.

    We also generate revenue from building Web sites for local merchants,
running display ads in our yellow pages directory and hosting Web sites on our
servers. In February 1999, we implemented what we refer to as our merchant
aggregation program through a strategic alliance with Discover Financial
Services. This program is aimed at companies that have existing relationships
with small businesses in order to sell our Web site creation, hosting and
advertising services to local merchants. We expect the amount of revenue
generated from the sale of these services to increase as a result of this
program. We recognize customer acquisition fees from this program when the Web
site construction is complete. We recognize revenue on a monthly basis from the
creation and hosting of display ads and Web sites as services are provided.
During 1999, approximately 21% of our total revenue was derived from our
merchant aggregation program.

    Our cost of revenue consists primarily of expenses paid to third parties
under data licensing agreements, as well as other direct expenses incurred to
maintain the operations of our Web site. These direct expenses consist of data
communications expenses related to Internet connectivity charges, salaries and
benefits for operations personnel, equipment costs and related depreciation,
and the costs to run our data center, which include rent and utilities. We
anticipate that our cost of revenue will increase in absolute dollars in the
future as a result of hiring additional employees and purchasing additional
equipment and outside services. Cost of revenue as a percentage of revenue has
varied in the past, primarily as a result of fluctuations in our Web site
traffic and, to a lesser extent, the cost of third-party content and
technology.

    Our sales and marketing expense consists primarily of costs associated with
Web site promotion, third-party revenue share costs, advertising and creative
production expenses, employee salaries and benefits, public

                                       27
<PAGE>

relations, market research and a pro rata share of occupancy and information
system expenses. We expect sales and marketing expense to increase in absolute
dollars as we continue to expand our marketing programs and our sales force and
incur advertising expenditures associated with our CBS-related promotion and
branding, carriage fees, and other marketing expenses associated with building
our merchant aggregation program. We expect to record the net present value of
the $95.0 million of advertising and promotion services from CBS as sales and
marketing expense as incurred through June 2006.

    Our product development expense consists primarily of employee salaries and
benefits, fees for outside consultants and related costs associated with the
development of new services and features on our Web site, the enhancement of
existing products, quality assurance, testing and documentation and a pro rata
share of occupancy and information system expenses. We expect product
development expense to increase in absolute dollars in the future as we
maintain and upgrade our Web site.

    Our general and administrative expense consists primarily of employee
salaries and benefits and other personnel-related costs for executive and
financial personnel, as well as legal, accounting and insurance costs and a pro
rata share of occupancy and information system expenses. We expect that our
general and administrative expense will increase in absolute dollars as we
continue to expand our staffing to support growing operations and facilities,
and incur expenses relating to our new responsibilities as a public company.

    We have experienced substantial net losses since our inception. As of
December 31, 1999, we had an accumulated deficit of $21.0 million. To date, we
have made no provision for income taxes. These net losses and accumulated
deficit resulted from our lack of substantial revenue and the significant costs
incurred in the development of our Web site and the establishment of our
corporate infrastructure and organization. We expect to increase our
expenditures in all areas in order to execute our business plan, particularly
in sales and marketing and in product development.

Years ended December 31, 1999 and 1998

    Revenue. Revenue increased to $8.3 million for the year ended December 31,
1999 from $6.5 million for the year ended December 31, 1998. This $1.8 million
increase consisted primarily of an increase of $309,000 in syndication and
license revenue, primarily due to new customer agreements and an increase of
$1.7 million due to the launch of our merchant aggregation program and the
commencement of our strategic

alliance with Discover Financial Services in February 1999, offset in part by a
$275,000 decrease in advertising revenue due primarily to the termination of
the America Online agreements. In 1999, one customer, Discover Financial
Services, accounted for 22.7% of our revenue. In 1998, QuikPage, Inc. accounted
for 10.2% of our revenue and two other customers accounted for 11.9% and 10.5%
of our revenue.

    Cost of revenue. Cost of revenue increased to $2.0 million, or 23.7% of
revenue, for the year ended December 31, 1999 from $1.3 million, or 20.0% of
revenue, for the year ended December 31, 1998. The dollar increase and
resulting percentage increase were primarily due to amortization expense
related to a software license of $306,000 and Web site maintenance expenses of
$330,000 incurred in connection with our merchant aggregation program.

    Gross profit increased to $6.3 million for the year ended December 31, 1999
from $5.2 million for the year ended December 31, 1998. Gross profit dollars
increased primarily due to higher revenue. Due to the increased costs, as a
percentage of revenue, gross profit percentage for the year ended December 31,
1999 decreased to 76.3% from 80.0% for the year ended December 31, 1998.

    Sales and marketing. Sales and marketing expense increased to $11.2
million, or 135.3% of revenue, for the year ended December 31, 1999 from $5.9
million, or 89.8% of revenue, for the year ended December 31, 1998. The
increase in 1999 of $5.3 million was primarily related to the CBS non-cash
advertising expense of $4.0 million, along with increased telemarketing fees of
$1.0 million, other advertising expenses of $897,000, and program expenses of
$616,000 related to our merchant aggregation program, offset by decreased
carriage fees of $1.4 million resulting from the termination of the America
Online agreements in 1998.

    Product development. Product development expense decreased to $1.9 million,
or 23.2% of revenue, for the year ended December 31, 1999 from $3.2 million, or
48.8% of revenue, for the year ended December 31, 1998. This decrease was
primarily due to the fact that product development expense for the year ended
December 31, 1998 included $1.4 million we expensed as incomplete technology
related to the Maps On Us technology acquisition.

    General and administrative. General and administrative expense increased to
$1.8 million, or 22.0% of revenue, for the year ended December 31, 1999 from
$1.1 million or 17.3% of revenue, for the year ended December 31, 1998. The
increase was primarily due to salaries associated with newly hired personnel
and related costs of $575,000 required to manage our growth and facilities
expansion, as well as increased legal, accounting, and consulting fees of
$215,000.

    Interest income (expense), net. Interest expense decreased to $149,000, or
1.8% of revenue, for the year ended December 31, 1999 from $404,000, or 6.2% of
revenue, for the year ended December 31, 1998. The dollar decrease in expense
was primarily due to increased interest income of $129,000 earned on the funds
available from the CBS investment in June 1999.

Years ended December 31, 1998 and 1997

    Revenue. Revenue increased to $6.5 million for the year ended December 31,
1998 from $650,000 for the year ended December 31, 1997. The $5.9 million
increase in 1998 was primarily due to increased advertising revenue of $3.6
million due to the growth in traffic primarily related to our agreements with
America Online and increased syndication and license revenue of $2.3 million
due to various new customer agreements obtained in 1998. For the year ended
December 31, 1998, QuikPage, Inc. accounted for 10.2% of our revenue and two
other customers accounted for 11.9% and 10.5% of our revenue. For the year
ended December 31, 1997, one customer accounted for 13.7% of our revenue.

                                       29

    Cost of revenue. Cost of revenue increased to $1.3 million, or 20.0% of
revenue, for the year ended December 31, 1998 from $793,000, or 122.0% of
revenue, for the year ended December 31, 1997. The dollar increase was
primarily due to increases in depreciation and amortization and data licensing
fees.

    Gross profits were $5.2 million, or 80.0% of revenue, for the year ended
December 31, 1998, compared to ($143,000), or (22.0)% of revenue, for the year
ended December 31, 1997.

    Sales and marketing. Sales and marketing expense increased to $5.9 million,
or 89.8% of revenue, for the year ended December 31, 1998 from $2.3 million, or
354.8% of revenue, for the year ended December 31, 1997. The increase of $3.6
million in 1998 was primarily attributable to increased America Online-related
carriage fees of $2.5 million, as well as revenue sharing expenses relating to
our strategic alliances of $907,000.

    Product development. Product development expense increased to $3.2 million,
or 48.8% of revenue, for the year ended December 31, 1998 from $2.1 million, or
324.2% of revenue, for the year ended December 31, 1997. The increase in 1998
of $1.1 million primarily resulted from expenses related to our purchase of the
Maps On Us technology in May 1998.

    General and administrative. General and administrative expense increased to
$1.1 million, or 17.3% of revenue, for the year ended December 31, 1998 from
$776,000, or 119.4% of revenue, for the year ended December 31, 1997. The
increase in 1998 of $354,000 was primarily due to an increase in the allowance
for doubtful accounts of $263,000 related to the increase in revenue and
accounts receivable, as well as increased personnel expenses of $206,000,
offset in part by decreases in outside services of $151,000.

    Interest income (expense), net. Interest expense increased to $404,000 for
the year ended December 31, 1998, from interest income of $4,000 for the year
ended December 31, 1997. The increase in 1998 in expense was primarily due to
increased interest expense of $350,000 in 1998 on increased borrowings from
Banyan Worldwide to fund working capital for operations, as well as reduced
interest income resulting from decreased cash balances available for investing.

Quarterly Results of Operations

    The following tables set forth our unaudited quarterly results of
operations for each of the eight fiscal quarters in the period ended December
31, 1999. This information has been derived from unaudited interim financial
statements, that, in our opinion, have been prepared on a basis consistent with
the financial statements contained elsewhere in this prospectus and include all
adjustments, consisting of only normal recurring adjustments, necessary for a
fair statement of the information when read in conjunction with our financial
statements and notes thereto. Our results of operations for any quarter are not
necessarily indicative of results for any future period.

    We have experienced significant fluctuations in revenue, expenses and
results of operations from quarter to quarter. Although we do not believe our
business is seasonal, we do experience fluctuations in the traffic to our Web
site during various times during the year, most notably around certain holiday
periods, which may impact our revenue. We expect these fluctuations to
continue. A significant portion of our revenue has been generated from a
limited number of customers. We anticipate that our results of operations in
any given period will continue to depend to a significant extent upon sales to
a small number of customers. It is difficult to predict the timing of future
contracts to these and other customers due to the length of our sales cycle in
syndication and advertising.

    Our agreements with America Online terminated in the fourth quarter of
1998. This termination adversely affected our results in the first two quarters
of 1999 because America Online had previously been responsible for a large
portion of our traffic and associated revenue.

    We have also experienced significant variations in our quarterly gross
profits. Our gross profit has varied due to the volume of traffic to our Web
site, which causes fluctuation in our revenue, direct costs and sales and

                                       31
<PAGE>

marketing expenses. Our product development and general and administrative
expenses have fluctuated on a quarterly basis primarily as a result of the
timing and number of additions in personnel and compensation and related costs.

    We believe that period-to-period comparisons of our historical results of
operations are not meaningful and should not be relied upon as an indication of
future performance.

Incomplete Technology Write-Off

    On May 18, 1998, we acquired the Maps On Us Internet mapping technology
from Lucent Technologies Incorporated for $1.6 million. The technology was
acquired to integrate it into our directory Web site.

    A significant portion of the technology acquired was deemed incomplete as
it did not meet the criteria for capitalization. The technology was incomplete
because the technology required a substantial development effort by us in order
to successfully integrate the Maps On Us technology into our Web site. The
technology had no alternative future use to us inasmuch as we had acquired the
technology to improve and integrate it into our Web site and not to market it
as a standalone product. Further, we had no other product, line of business or
product development project that could use the technology. Therefore, we
recorded a charge to product development of $1.4 million for the purchase of
incomplete technology in 1998.

    We valued the acquired incomplete technology using a risk adjusted
discounted cash flow approach including stage of completion assumptions. We
evaluated the Maps On Us technology using extensive interviews and analysis of
data concerning the state of the technology and the required development work.
The evaluation assumed an average growth of Maps On Us related advertising
revenue of 54% based on expectations in the industry at the time, a gross
profit of 70% to 80% and sales marketing and administrative expenses of 27% to
36% of revenue. These assumptions should not be construed as forecasts of the
Maps On Us related future operating results. We used a discount rate of 25% in
the evaluation, reflecting the difficulties and uncertainties in completing the
development effort and the inherent uncertainty of predicting cash flows in the
Internet industry. We estimated the technology's stage-of-completion at the
date of acquisition to be 80% based on estimated costs incurred by Lucent prior
to the acquisition of the technology of $1.0 million and our estimated cost to
complete of $250,000. Our estimate of costs incurred prior to the purchase is
based on our understanding of the technology. No development cost data was made
available by Lucent.

    The acquired technology was incomplete because a significant amount of
coding, testing and integration was required before the technology would be
viable for use on our Web site. The components of the technology which required
significant development work included the integration of our business data with
the Maps On Us geocoding approach, the development of new tools for the
management and online modification of geocoding information, the design and
integration of the user interface and the cross linkage of the technology with
our advertising technology. The ability to integrate the technology with our
Web site was critical to achieving technological feasibility and was uncertain
at the time of acquisition. We have now completed the design and integration of
the Maps On Us technology on our Web site. The cost of completing the
development effort was $200,000.

Liquidity and Capital Resources

    Since our inception, we have been funded primarily by Banyan Worldwide
under our convertible preferred note facilities and through sales of capital
stock. In 1999, Banyan Worldwide converted approximately $11.7 million of the
outstanding principal and interest under our convertible preferred note
facilities into preferred stock. The outstanding amount of principal and
interest under this facility is convertible at the option of Banyan Worldwide
into shares of series D preferred stock at a rate of $11.00 per share.
The interest rate in effect at December 31, 1999 was 5.74%. As of December 31,
1999, we had approximately $3.9 million available and there was no outstanding
balance under this facility. Upon completion of this offering, this facility
will automatically terminate in full and any outstanding principal and interest
will be

                                       32
<PAGE>


converted into shares of our series D preferred stock at the then-applicable
conversion rate. Any shares of our Series D preferred stock which are issued
will convert automatically into shares of common stock upon completion of this
offering.

    In November 1996, we received a $3.0 million equity investment from America
Online and Digital City Inc. We used these funds for working capital to fund
our operations. On June 30, 1999, we received $5.0 million in cash as part of
an equity investment from CBS.

    As of December 31, 1999, we had cash and cash equivalents totaling $3.6
million.

    Net cash used for operating activities for the year ended December 31, 1999
was $2.8 million, primarily due to a net loss of $8.8 million and increases in
accounts receivable and other current assets, offset in part by the increases
in accounts payable and accrued expenses.

    Net cash used for investing activities for the year ended December 31, 1999
was $942,000. Investing activities for the periods were primarily purchases of
equipment, consisting largely of computer equipment.

    Net cash provided by financing activities for the year ended December 31,
1999 was $6.9 million, primarily due to the CBS transaction and funds provided
to us by Banyan Worldwide.

    Our other financial commitments consisted of a note payable related to the
purchase of the Maps On Us technology of $600,000 as of December 31, 1999.

    As of December 31, 1999, we had net operating loss carryforwards of
approximately $14.2 million available for federal, state and foreign purposes
to reduce future taxable income expiring on various dates beginning in 2001.
Under the provisions of the Internal Revenue Code, some substantial changes in
our ownership may have limited, or may limit in the future, the amount of net
operating loss carryforwards which could be utilized annually to offset future
taxable income. Based on our current financial status, realization of our
deferred tax assets is uncertain. Accordingly, a valuation allowance for the
entire deferred tax asset amount has been recorded.

    Since our inception, we have significantly increased our operating
expenses. We anticipate that we will continue to experience significant
increases in our operating expenses through at least 2001, and that our
operating expenses and capital expenditures will constitute a material use of
our cash resources. We expect to incur significant expense increases as we
attempt to brand our name and increase the traffic to our Web site. These
increases are expected to result from substantial advertising expenses and
increased marketing expenses associated with our merchant aggregation program.
Additionally, we expect to add personnel in all departments, which will
increase salaries and benefits and other personnel-related expenses. In
addition, we may utilize cash resources to fund acquisitions or investments in
businesses, technologies, products or services that are complementary to our
business. Due to the fact that our primary marketing expense will be the use of
our non-cash CBS-related advertising, we believe that the funds currently
available along with support from Banyan Worldwide will be sufficient to meet
our anticipated cash requirements for at least the next 12 months. Including
the proceeds of this offering, we expect to have sufficient funds to meet our
anticipated cash requirements for at least the next 24 months. If cash
generated from operations is insufficient to satisfy our liquidity
requirements, we may seek to sell additional equity or debt securities, or
obtain additional credit facilities. However, there can be no assurance that we
would be successful in obtaining this additional funding. The issuance of
additional equity or convertible debt securities could result in additional
dilution to our stockholders.

Market Risk

    To date we have not utilized derivative financial instruments or derivative
commodity instruments. We invest our cash in money market funds, which are
subject to minimal credit and market risk. We believe the market risk
associated with these financial instruments is immaterial.

Year 2000 Readiness Disclosure

    Many existing computer programs and systems include computer code in which
calendar year data is abbreviated to only two digits. As a result, some of
these programs and systems could fail to operate or fail to produce correct
results if "00" is interpreted to mean 1900, rather than 2000. We refer to this
as the year 2000 problem. We use software, computer technology and services
that are internally developed or provided by third parties that may fail due to
the year 2000 problem.

    In April 1999 we initiated our formal year 2000 project to assess our year
2000 risks and to develop any necessary corrective action plans. To date, we
have taken the following actions under our year 2000 project:

  .   we have reviewed all hardware and software used in the operation of our
      Web site, including internally developed software and third-party
      hardware and software that is used in the operation of our Web site;

  .   we have upgraded the hardware and software which require modifications
      to be year 2000 ready;

  .   we have obtained publicly available year 2000 readiness statements from
      third parties who provide hardware, embedded software or packaged
      software used in the operation of our Web site and from Exodus
      Communications, which provides us with Web hosting facilities for our
      Web site; and

  .   we have completed an assessment of the potential effects and costs of
      remediating the year 2000 problem on our office and facilities
      equipment.

In general, we have not contacted third parties regarding year 2000 readiness
other than to obtain publicly available year 2000 readiness statements
described above.

    Our employees performed all significant work related to our year 2000
project. We did not hire any additional employees or incur significant
consulting expenses to perform this work. We purchased approximately $1,000 of
software upgrades and expended $50,000 on hardware, infrastructure and desktop
upgrades. Although we likely would have incurred these costs in the normal
course of our business activities, the upgrades replaced non-year 2000 ready
software and hardware. We do not expect to incur significant additional
expenses in connection with our year 2000 readiness project.

    Our business depends upon the ability of consumers and local merchants to
access our Web site from their computers. Consumers who visit our Web site and
the local merchants in our network may not be able to access our Web site due
to their own year 2000 problems. Our users and our local merchant customers are
diverse and highly fragmented, and we have not attempted to contact them to
assess their year 2000 readiness. Many consumers and local merchants may not
have the internal capability or other resources necessary to assure their year
2000 readiness.

    We also depend on the integrity and stability of the Internet. Our ability
to assess the year 2000 readiness of the general Internet infrastructure
necessary to support our operations is limited and relies solely on generally
available news reports, surveys and comparable industry data. Based on these
sources, we believe that most entities and individuals that rely significantly
on the Internet are reviewing and attempting to address issues relating to year
2000 compliance. We cannot predict whether these efforts will be successful in
reducing or eliminating the potential negative impact of year 2000 issues. Our
business would suffer if there were a disruption in the ability of consumers
and local merchants to access the Internet or portions of it.

                                       34

    In addition to computers and related systems, the operation of office and
facilities equipment, such as fax machines, security systems and other common
devices, may be affected by the year 2000 problem. Banyan Worldwide supplies
some of our office and facilities equipment. Because we did not purchase that
equipment, we may be unable to cost-effectively remediate any year 2000 issues
relating to that equipment.

    Banyan Worldwide also provides us with various administrative
telecommunications and other services. Our business relies on functional use of
Banyan Worldwide's internal computer systems to process dates after December
31, 1999. Based on Banyan Worldwide's publicly available year 2000 readiness
statements, we believe that Banyan Worldwide has taken steps to assure its year
2000 readiness. If these systems are compromised by year 2000 problems, Banyan
Worldwide's ability to provide us with services could be impaired.

    In December 1999, we completed the transition of our primary hosting
facility for our Web site from our corporate headquarters to a third-party
hosting facility. Although this transition was not undertaken specifically to
address year 2000 compliance problems, we believe that this transition
mitigates our risk of facility- or Internet-related failures caused by the year
2000 problem.

    At this time, we have not developed and do not expect to develop a
contingency plan to address situations that may result if we, or any third
parties on which we rely, experience problems relating to our or their failure
to achieve year 2000 readiness. The cost of developing and implementing a
contingency plan, if necessary, could be significant. Any failure of our
material systems, the systems of the consumers that visit our Web site, the
systems of the merchants participating in our network, the systems of third
parties supplying our products and services, the systems of Banyan Worldwide or
the Internet to be year 2000 compliant could have negative consequences for us.

    We believe our most reasonably likely worst case scenarios related to year
2000 risks are:

  .   failure of internal software causing a shutdown of our Web site;

  .   corruption of data contained in our information systems;

  .   hardware failure; and

  .   the failure of infrastructure services provided by third parties, such
      as electricity, phone service, etc.

    As of the date of this prospectus, we have not experienced any material
year 2000 problems relating to our software, computer technology or services
nor are we aware of any material year 2000 problems relating to the software,
computer technology or services of any third parties on which we rely.

Recently Issued Accounting Pronouncement

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." The new standard established accounting
and reporting standards for derivative instruments, including some derivative
instruments embedded in other contracts, and for hedging activities. SFAS No.
133, as amended by SFAS No. 137, is effective for all quarters for fiscal years
beginning after June 15, 2000. We do not expect SFAS No. 133 to have material
effect on our financial position or results of operations.

                                    BUSINESS

Overview

    We are a leading Internet-based local merchant network interconnecting
consumers, merchants and national advertisers. Through our Web site,
Switchboard.com, we offer our users local information about people and
businesses across the United States, including listings of over 96 million
individuals, 12 million businesses and four million e-mail addresses. Our Web
site provides a broad range of functions, content and services designed to
connect consumers and businesses on the Internet.

Industry Background

    The Internet is fundamentally changing how millions of people and
businesses share information. The number of Internet users worldwide is
projected to increase to 500 million by the end of 2003 from approximately 195
million in 1999, according to International Data Corporation. IDC projects
total business-to-consumer online commerce will increase to $178 billion in
2003 from approximately $31 billion in 1999. Forrester Research estimates that
online advertising in the United States will increase to $17.2 billion in 2003
from approximately $1.3 billion in 1998.

    Historically, consumers have used multiple methods to identify and seek out
businesses that provide specific products and services in their area.
Traditional printed materials for finding local information include yellow
pages directories and local maps. These sources, however, typically cover
narrowly defined geographic areas and some are updated only once per year.
Telephone directory assistance allows consumers to get updated information, but
is often more costly to use and only provides telephone numbers and addresses.

    Recently, consumers have turned to online directories as an alternative
source of local information. These directories can provide more up-to-date
results, and can extend beyond limited geographic boundaries. Many of today's
online directories, however, are merely extensions of traditional printed
directories, offering repackaged content in a static "listings" style layout.
Consumers continue to encounter difficulties obtaining the relevant information
they seek because of the volume and fragmented nature of online local
information.

    As the number of users online continues to grow, the Internet is becoming
an accepted and viable commercial and marketing medium. Local merchants are
increasingly recognizing the need to establish an online presence to remain
competitive. According to Forrester Research, the aggregate number of
businesses with 100 or fewer employees with a Web presence is projected to
increase to approximately 4.2 million by the end of 2003 from approximately 2.1
million in 1999. Forrester Research also predicts local online commerce will
increase to $6.1 billion in 2003 from approximately $680 million in 1998.

    Creating an online presence, however, is often a difficult and costly task
for small businesses. Local merchants may struggle with the financial,
technical and administrative challenges associated with creating, maintaining
and promoting an effective Web site. To compete online and to meet evolving
consumer expectations, merchants need more convenient and cost-effective ways
to build, promote and enhance the functionality, services and content of their
Web sites.

    We believe that consumers demand an online service where they can easily
find detailed information about local merchants and their products and
services. We also believe that merchants demand a convenient and cost-effective
approach to creating a Web presence that will reach large numbers of these
consumers. We believe an opportunity exists to satisfy both constituencies with
a single online destination.

The Switchboard Solution

    Our local merchant network is focused on bringing consumers, merchants and
national advertisers together at a single online destination. We connect
consumers searching for specific products and services with the merchants that
provide them. Our online network:

  .   provides consumers with detailed local information about people and
      businesses across the United States;

  .   gives local merchants a fast, easy, cost-effective way to get their
      businesses represented online;

  .   facilitates commerce by connecting them with consumers; and

  .   provides an effective online lead generation engine for these local
      merchants and for national advertisers that reaches consumers motivated
      to buy products and services in specific geographic locations.

 Benefits to Consumers

    Extensive information base. We provide consumers with detailed local
information, including listings of over approximately 96 million individuals,
12 million businesses and four million e-mail addresses. Switchboard allows
consumers to search for people and businesses beyond the geographic boundaries
of traditional print directories. We offer a free alternative to directory
assistance charges and eliminate the need for consumers to know a specific city
or area code information to obtain the desired results. Our powerful search
capabilities, interactive maps and driving directions allow consumers to locate
businesses based on proximity to their home, office or a planned travel
destination. We link to a growing base of over 350,000 business Web sites and
provide consumers with a powerful tool to research and compare competitive
offerings and to ultimately conduct business, both online and offline. In
addition, our patented ad serving technologies present consumers with multiple
merchant advertisements and allow them to rapidly screen and examine the
information they seek.

    Powerful search capability. Our proprietary directory architecture,
combined with our intuitive screen displays, allows search results to be
delivered quickly with few page views. These search results can be organized
alphabetically or by geographical proximity. Our innovative "What's Nearby?"
service enables a consumer to input an address anywhere in the country and find
detailed information about nearby businesses, people, government and points of
interest and regional maps. This feature is ideal for travel planning, both
personal and business, as well as for people moving or changing job locations
who need to familiarize themselves with their new surroundings.

    Integrated maps and driving directions. Our Maps On Us maps and driving
directions technology is fully integrated with our directory services. Once a
consumer identifies a desired address, Maps On Us allows the consumer to plot
the most effective route to that destination, including intermediate stopping
points. Consumers may also store previously accessed maps and directions in a
personal address book.

    Personalized experience. We offer our registered users the ability to
personalize their online experience. Users can control their listings in our
white pages and can add information about their profession, education,
affiliations and other interests. Users can choose from a variety of privacy
options to shield various portions of their online identities, and can store
their bookmarks in Switchboard for easy access from any computer. We also offer
personal home pages and custom e-mail accounts.

 Benefits to Merchants

    Fast, cost-effective Web presence. Our robust system architecture and
sophisticated Web site building tools enable us to quickly and cost effectively
develop and deploy multi-page Web sites for local merchants. We provide local
merchants with a visible Web presence, while eliminating the technical,
administrative and financial challenges typically associated with creating and
maintaining an effective Web site.

                                       37
<PAGE>

    Participation in a leading online local merchant network. We provide local
merchants with access to our nationally recognized, highly trafficked merchant
network, Switchboard.com. Unlike traditional phone books and directory
services, our online directory service, maps and driving directions provide
merchants with exposure to customers beyond their immediate local area. We
acquire and aggregate local merchant customers into our branded directory and
our network of syndicated directories. We believe our alliance with CBS further
enhances our brand and offers the opportunity to generate additional traffic to
our merchant customers.

    Lead generation. Our online merchant network attracts potential consumers
who provide information about the types of products and services they are
seeking in a particular location. Switchboard.com helps our merchant customers
to connect with consumers and facilitates their communications with their
customers through e-mail, fax or regular mail. We believe that this direct line
of communication fosters stronger relationships between local merchants and
consumers.

 Benefits to National Advertisers

    We offer advertisers a wide range of advertising options. Our patented ad
serving technologies allow advertisers to target specific types of consumers in
each of our white pages, yellow pages, maps and Web search offerings. A
national advertiser can buy a site-wide banner to re-enforce its brand, an in-
category sponsorship to drive traffic to specific offers on their site and a
yellow pages trademark ad to drive traffic to local outlets. These options give
advertisers significant flexibility to construct customized campaigns designed
to drive traffic at the local or national level to businesses both offline and
online.

Strategy

    We intend to be the leading Internet-based network connecting customers
with local merchants and providing merchants with the content, services and
functionality they need to effectively compete online. We plan to enhance our
lead generation capabilities by building traffic on our Web site, increasing
the number of merchants we serve and expanding the breadth of our services. Key
elements of our strategy include:

    Building brand. We believe that building greater awareness of the
Switchboard brand is critical to expanding our user base and to building our
local merchant network. We intend to expand our use of advertising, public
relations and other marketing programs designed to promote our brand and build
user and merchant loyalty. In October 1999, we launched our "Think Outside the
Book" national advertising campaign designed to attract new consumers to
Switchboard.com and build awareness among merchants in local markets. We intend
to build on our relationship with CBS by promoting our brand across multiple
media, including national television, outdoor advertising and radio. In
addition, we expect to pursue other public relations and marketing programs.

    Expanding merchant aggregation programs. We have established strategic
alliances with companies that have existing relationships with numerous small
businesses. We refer to these companies as merchant aggregators. We believe we
can attract a larger base of merchants by working together with these merchant
aggregators to implement co-branded sales and marketing programs. In February
1999, we launched our merchant aggregation program through a strategic alliance
with Discover Financial Services. We plan to continue to work with Discover and
other companies to offer our products and services to their small business
customers. We believe that by expanding our merchant aggregation program we can
increase the number of merchants in our network and provide greater value to
consumers, existing merchants and national advertisers.

    Creating specialized vertical directories. We are developing targeted
syndication packages designed to attract vertical content providers seeking to
enhance their sites by offering specialized directories of local merchants in
categories relating to their content. We believe that providing relevant
content for researching products and services will increase the frequency and
duration of visits to our Web site. By forming relationships with providers of
this content, we believe we will enhance the effectiveness of our site for

                                       38
<PAGE>

consumers and for advertisers seeking targeted audiences. By syndicating these
specialized directories, we expect to deliver more highly qualified customer
leads to our local merchants. We anticipate that some of these vertical content
providers will also participate in our merchant aggregation program since they
may have merchant relationships of their own.

    Extending technology leadership. We intend to update and enhance the
features and functionality of Switchboard.com to continue to improve the user's
experience and provide a comprehensive, cost-effective online presence for
merchants. We are developing service enhancements aimed at our users, including
increased personalization and customization features and expanded search
options. We plan to offer merchants a more sophisticated Web presence by
integrating online commerce applications into our local merchant services. We
are pursuing additional opportunities to expand network access and merchant
services across a variety of wireless devices and other Internet-enabled
appliances. We believe that technology leadership will continue to be important
to offer compelling services and functionality.

    Expanding internationally. We intend to expand internationally as
opportunities arise. We expect to accomplish this expansion by entering into
strategic alliances with companies that are well-positioned to aggregate
merchants in local markets, internationally. In connection with our strategic
relationship to license our technology to Bell ActiMedia, Inc., a wholly owned
subsidiary of Bell Canada, we enhanced our technology infrastructure. We
believe this enhanced technology infrastructure will help us to take advantage
of other international opportunities.

Switchboard.com

    The foundation of our local merchant network is our Web site,
Switchboard.com. The site provides a broad range of functions, content and
services designed to connect consumers and businesses on the Internet. Key
features of Switchboard.com include:

 Directory Services

    Our yellow pages, white pages and e-mail directory services provide
consumers with information about people and businesses and, in many cases,
detailed information about the products and services those businesses offer. In
addition to listing information found in traditional directories, our
directories include integrated maps and directions, information about nearby
businesses, display advertisements and links to merchant Web sites. Consumers
can use our directory services to search by category, geography and names.

    We license yellow and white pages directory information under a non-
exclusive agreement with infoUSA. Based upon infoUSA's extensive listings and
verification procedures and our management's understanding of available
alternatives, we believe its database is the most comprehensive and accurate
available database of business and residential information in the United
States. infoUSA is obligated to provide us with updated data monthly. Under
this agreement, we pay infoUSA annual royalties. We recently extended our
agreement with infoUSA to December 30, 2002.

    To increase our coverage to include Canada, we entered into a relationship
with Bell ActiMedia in September 1999. Under the terms of our three-year non-
exclusive agreement with Bell ActiMedia, we agreed to develop, customize, host
and license versions of our white pages, our yellow pages and other of our
services for use by Bell ActiMedia on its own Web sites and Web sites owned by
affiliates of Bell Canada Enterprises, the parent company of Bell Canada. Bell
ActiMedia pays us development and engineering fees, annual license fees and a
share of their revenue. We also agreed with Bell ActiMedia to include links to
each other's Web sites on our Web sites and to limited licenses of each other's
trademarks.

    Our directories provide users, merchants and advertisers with powerful
tools to customize how they represent themselves on the Web. Users and
merchants can edit their listings in our directories by updating and
supplementing information about themselves. These tools help users and
merchants to be found and ensure that the information about them is accurate
and personalized.

                                       39
<PAGE>

    Our e-mail address database provides users with access to e-mail addresses
provided by our own users and a third-party source. Registered users can use
our patented "Knock Knock" technology to control access to their e-mail
address. As a privacy benefit to our users, this service functions as an e-mail
equivalent of caller ID, allowing users to screen e-mails while shielding their
e-mail address from the sender.

 Localized Content

    Our "What's Nearby?" service provides relevant information about the
surrounding local merchants and establishments related to a user search.
"What's Nearby?" provides links to local businesses in the entertainment,
travel, recreation, shopping, health and real estate sectors based on the
user's target search location. In addition, this service provides mapping
features and links to Web sites related to the region, government offices,
points of interest and other useful information. This information is integrated
into our white pages, yellow pages and mapping features allowing users to
access businesses, information and services in the context of their searches.

 Maps and Directions

    Our Maps On Us technology integrates maps and driving directions into many
areas of our Web site. Maps generated by Maps On Us provide users with
sophisticated viewing options including multiple levels of zoom, full and half
screen pans, map center selection, labeling of roads and other points of
interest, map size, color or monochrome rendering and latitude/longitude
display. Our technology provides users with a powerful tool to plan the
shortest or fastest route from a starting point to a destination including up
to five intermediate locations. They can also choose to avoid or use major
highways. Our "best tour" function lets users enter a number of locations in
any order and will designate the most efficient route from start to finish.
Maps are displayed with detailed turn-by-turn directions, all of which can be
forwarded to others by e-mail.

    Users can also incorporate the "What's Nearby?" service to identify and
highlight local businesses that are in the vicinity of the mapped selection or
on the created route. In addition to the core features, registered users can
also save maps and routes previously generated by Maps On Us, and store a list
of addresses, markers or favorite places in an address book. Stored information
is highlighted on subsequent maps or route requests.

 Web Searching Tools

    Our Web searching technology provides users with a powerful search
alternative to existing key-word based search engines. Results are optimized to
deliver the most relevant Web sites instead of Web pages, making searching
easier and more efficient. These sites are linked in a way that allows users to
navigate through them based on their relationship to each other as well as find
them through keyword searches.

    Our technology allows registered users to personalize bookmarks and access
these bookmarks from any computer though the Switchboard.com site. As an added
benefit, we can supplement these personalized bookmarks with related Web sites.
Users can also use our bookmark editing tools to add, delete and re-classify
links. Using this feature, our users can move from computer to computer but
still enjoy the same set of bookmarks when they access the Web.

 Community

    We provide the following services to enhance the user experience on our
site:

  .   Free e-mail. Users can get free e-mail with our comprehensive set of
      e-mail options, including customized addresses, multiple accounts and
      other enhanced services.

  .   Free homepages. With our personal home page builder, users can easily
      create sophisticated personal Web sites by selecting from a gallery of
      layouts, themes, colors and clip art. Users can also add original
      text, favorite links or their own pictures.

                                       40
<PAGE>

  .   Message boards. We offer users the ability to post and read messages
      on message boards across a variety of topics including humor,
      relationships, religion, sports, genealogy, politics, teens and
      missing persons. In addition, we organize our message boards by city
      or state, allowing regional users to interact and communicate.

  .   Shopping area. From our shopping area, users can purchase gifts and
      merchandise, as well as electronic photos, greeting cards, flowers and
      other items, and have them sent to relatives, friends and business
      associates located through our directories.

 Other Services

    In December 1999, we announced plans to offer long distance calling over
the Internet to consumers using our Web site through a relationship with
Net2Phone, Inc. and plans to offer Web-based file delivery, handling and
storage services designed to make it easier for consumers using our Web site to
send and receive large files directly from their Web browsers through a
relationship with click2send.com, Inc.

Local Merchant Services

    We provide local merchants with a broad range of services to help them
establish, manage and expand their online presence as their business evolves.
Using a variety of proprietary and licensed technologies and services, we
provide small businesses with solutions to reach qualified consumers. Current
services provided to local merchants include:

  .   construction and hosting of multi-page Web sites with detailed
      business information;

  .   developing contact pages designed to connect potential consumers with
      merchants;

  .   integrated mapping and directions functionality powered by Maps On Us;
      and

  .   marketing services including display advertisements on Switchboard.com
      and affiliated sites.

    For those businesses seeking to construct their own Web site, we also offer
our Web site building tool, Ad Studio, which allows merchants to select from a
gallery of layouts and clip art, upload pictures and choose geographies and
categories in which their Web site will be seen.

Advertising

 Banner and Sponsorship Advertising

    We offer both site-wide banner and category-specific banner programs. We
provide standard run of site banner ad programs, which include full banners
across the top and bottom of pages and smaller banners on the navigation bar
that allow advertisers to take advantage of our high traffic volume.
Additionally, our patented banner ad serving technology enables us to place and
rotate category-specific banner ads of various sizes in targeted locations
throughout our site. We also sell sponsorship programs on a site-wide basis or
for various categories. Sponsorships are advertisements consistently and
prominently displayed on our Web site.

 Display Advertising

    We provide yellow pages-style display advertisements and ad management
tools to local merchants and national advertisers. We give advertisers a range
of location, category and ad size options at the local and national levels.
When shown on a computer screen, our display ads resemble traditional yellow
page advertisements. Our display ads rotate according to preset priority
placement rules which allow for each advertiser's display ad to be periodically
visible near the top of the page.

    Display advertisements are sold on a monthly or annual basis, and are
generally not subject to guaranteed impression levels or click-throughs. We
price and sell advertisements on the basis of ad size, search locations and
priority placement. Display advertisements are category specific and
geographically targeted. When clicked, display ads link the user to a Web site
of the advertiser's choosing. Options available to these advertisers include:

  .   display priority options designed to allow advertisers to pay to have
      their ads seen more frequently and prominently than others;

                                       41
<PAGE>

  .   trademark ads designed to allow national advertisers to represent
      outlets for their products based on their location in selected
      categories, for example "Our Dealers Near You";

  .   ads designed to allow national businesses to advertise in local
      category searches; and

  .   geographical options that allow merchants to place ads in a single zip
      code, within a radius around a specific location or nationwide.

 E-Commerce Advertising

    We offer advertisements on various pages on our Web site for advertisers
engaged in e-commerce. These advertisements can be placed under specific
headings near a white pages search result. We also provide links to our
shopping area near our white pages search results. In our shopping area, we
offer e-commerce advertisers the opportunity to promote product specials, as
well as link to their Web sites.

Syndication

    We license our products and services to other companies in order to
generate traffic on the Switchboard.com Web site. We refer to this as
syndication. Syndication extends the reach of our site and increases the value
proposition to our advertisers. As of December 31, 1999, we syndicated our
directories or maps on a variety of Web sites, including Ask Jeeves, the AtHand
Network, CBS.com and USATODAY.com.

    We recently announced plans to expand the scope of our syndication
relationships to include distribution of Switchboard content to users of mobile
telephones, through relationships with Phone.com, Inc. and Roku Technologies,
and to users of interactive television, through a relationship with WorldGate
Communications, Inc.

Strategic Alliances

    We have formed strategic alliances to:

  .   build our brand;

  .   increase the number of visitors to our Web site;

  .   support our expanding sales and marketing efforts; and

  .   develop compelling content, services and functionality for our Web
      site and for Web sites that we create for our local merchant
      customers.

    CBS Corporation. In June 1999, we entered into a strategic relationship
with CBS under which CBS became a stockholder of Switchboard in exchange for
$95.0 million in advertising and promotion through June 2006 across the full
range of CBS media properties, including its majority-owned radio and outdoor
advertising subsidiary, Infinity Broadcasting Corporation, and $5.0 million in
cash. We also received a license from CBS to use the "CBS" and CBS "eye" device
trademarks. In addition, CBS has agreed to place links to our Web site on CBS-
controlled Web sites, including CBS.com, and to use good faith efforts to
obtain similar links on other Web sites in which CBS has a non-controlling
interest. Our alliance with CBS is helping us to expand our advertising sales
resources both locally and nationally and delivers the credibility and backing
of a major media company.

    Discover Financial Services. In February 1999, we launched our merchant
aggregation partnership program with Discover Financial Services. The Discover
program provides us with access to Discover's merchant customer base. Discover
offers its merchant customers an online solution through Switchboard.com. This
relationship allows us to offer their base of merchants additional services and
functionality over time.

    Bell ActiMedia. To expand our content offering and increase our geographic
coverage, we entered into a three-year agreement in September 1999 with Bell
ActiMedia to provide directory services in Canada. This relationship is
intended to increase Canadian traffic, help us grow our local merchant base
outside the United States and enable us to provide Canadian information to our
U.S. users.

                                       42

Technology

    We have developed sophisticated technologies that enable rapid
dissemination of information requested by consumers using our Web site. These
technologies were conceived and developed by a staff of senior engineers
experienced in designing large-scale, distributed computer systems, a form of
computer architecture that divides system functionality over numerous
computers, each known as a server, to enhance overall system performance. We
also have particular strengths in the areas of database technologies,
advertising management and content customization.

 Directory Technology

    We have been affiliated with Banyan Worldwide, a pioneer of directory
technology, since our founding in 1996. Directories played a key role in the
large-scale, multiple-site distributed systems deployed by Banyan Worldwide
since 1983. Our founder, Dean Polnerow, designed and originally developed
StreetTalk, Banyan Worldwide's directory service. Building on this experience
to create our own proprietary directory technology, we created what we believe
to be the first national directory of U.S. residential information available on
the Internet, as well as our innovative and proprietary yellow pages business
directory.

 Site Design

    The Switchboard.com Web site was designed to provide high levels of
performance, scalability and reliability. The site is implemented as a set of
Windows NT servers which are organized into groups. Each group of servers
provides different parts of the overall site's functionality and each type of
functionality is provided by more than one group of servers. Individual servers
in a group can be added or removed without affecting the functional
capabilities of the site, and most changes required are managed automatically
by proprietary software that we developed. This distributed architecture is
designed to be highly scalable, which means that system capacity and
functionality can be easily and inexpensively increased, typically with minimal
or no time consuming software changes required. It is also designed to be
reliable, which means it is resistant to service interruptions and that the
unavailability of one or more servers does not necessarily affect the operation
of other servers or the site as a whole.

 Database Technologies

    We have developed technology designed to quickly exchange information
between the groups of servers that provide the interface consumers use to input
their requests for information with the groups of servers that store the
databases of information we use to respond to these requests. This technology
allows data from multiple databases to be accessed and combined, regardless of
its structure or content. This simplifies the development of new user
interfaces and facilitates database updates. Our database technology helps to
maximize our Web site performance through caching capabilities, which seek to
reduce response time by storing frequently requested information and predicting
which information will next be requested, and by automatically balancing the
tasks being performed by individual servers.

    Our database technology includes sophisticated query management techniques,
which enable requests for large amounts of data to be retrieved in segments
while reducing the computer processing time typically associated with these
operations using conventional design techniques. This enables ready access to a
large amount of data stored in any of the databases and results in faster
response to the user. Conventional databases often access previous results in
order to display successive results to a given query which increases response
time by performing redundant operations.

 Advertising Management

    Our ad placement technology is used primarily to control the frequency and
positioning of advertisements displayed on our Web site. This technology
rotates merchant ad displays in and out of prime locations on our yellow pages
screens according to priorities specifically purchased by our merchant
customers. We use an automated chain of software programs to securely
facilitate the addition and removal of both individual ads and large,
aggregated volumes of merchant advertising into the Switchboard.com yellow
pages.

                                       43
<PAGE>

    We have also developed a proprietary ad placement methodology which
provides a simple way for us to allow a merchant to focus its advertisement to
the surrounding communities it desires to target. This technology uses the
physical location of a business and a distance measurement selected by the
merchant to automatically determine the appropriate location targets. These ad
management tools and processes enable our direct sales force and authorized ad
resellers to remotely manage and control national, regional and local ad
campaigns.

 Content Customization

    We can customize the look and feel of the content we deliver in response to
customer inquiries so that it is consistent with the look and feel of our
syndication customers' own Web sites. This customization process is based on
the modular organization of functional elements of our content, such as white
pages, yellow pages, e-mail search and user registration. These modules
separate the functional elements from the layout elements, such as site
appearance, thus facilitating rapid development of customized interfaces for
our syndication customers. As we enhance or build new functional elements, the
underlying architecture enables us to deploy them across all of the Web sites
of our syndication customers.

 Production, Computer and Communications Equipment

    The production, computer and communications equipment used to operate the
Switchboard Web site and the Maps On Us Web site is located at Exodus
Communications, Inc.'s data center in Waltham, Massachusetts. The Exodus
facility offers physical security, full power failure protection and redundant
communications links. We operate a back-up of the Switchboard Web site in
Westboro, Massachusetts with automatic fail-over in the event of a catastrophic
facilities or communications failure at the Exodus location.

Marketing, Merchant Aggregation and Sales

 Marketing

    We have generated our traffic and merchant participation to date with
limited marketing. In October 1999, we launched an advertising campaign
designed to generate increased awareness of our site among consumers and
merchants. The cornerstone of this campaign is $95.0 million of advertising on
the CBS properties that we will receive through our strategic alliance with
CBS. This alliance allows us to take advantage of CBS's strong presence across
a variety of advertising media, including:

  .   radio networks;

  .   outdoor advertising; and

  .   the CBS television network.

    As part of the CBS initiative, in October 1999 we unveiled two 30 second
television commercials for broadcast in Boston, Chicago, Los Angeles, New York,
Philadelphia and San Francisco. These commercials challenge consumers and
businesses to "Think Outside the Book," and use our online directory service
instead of traditional ones.

    We employ a variety of online and offline advertising to promote our
service and generate additional traffic. Prior to our relationship with CBS, we
primarily relied upon promoting and marketing our service through syndication
relationships with telecommunications companies, Internet destination sites and
other companies. We plan to utilize a variety of media to market our online
services including online, print, direct mail, radio, television and outdoor
advertising. We have an ongoing public relations program and participate in
industry conferences and tradeshows.

 Merchant Aggregation

    To attract new merchants to our network, we have established strategic
affiliations with a number of organizations which have existing relationships
with, or databases of, local merchants. These relationships are designed to
help us cost-effectively reach the highly fragmented small business market.
Most of these relationships are with merchant aggregators. The merchant
aggregators contribute to the growth of our local merchant network by offering,
or allowing us to offer, our services to their merchant customers. In many
cases,

                                       44
<PAGE>

we market our services on a co-branded basis and generate sales through
outsourced telesales agents, or through our merchant aggregators' direct sales
forces. The other relationships are with companies that have compiled databases
of information about local merchants. These relationships provide us with
information enabling us to supplement basic listing information with links to
merchant Web sites.

    We currently have relationships with Bell ActiMedia, Discover Financial
Services, QuikPage, Inc., and several other companies. Under these
arrangements, we typically receive payments from these parties for yellow pages
advertisements on our Web site they sell to their customers, development fees
and/or license fees. In some cases, we receive payment directly from merchants
for services and then share this revenue with the merchant aggregator. Discover
is currently our primary merchant aggregator. Under our arrangement with
Discover, we co-market our local merchant services to Discover merchant
customers and share the resulting revenue and marketing expenses.

 Sales

    Our internal sales force coordinates our national sales efforts. They are
dedicated to selling advertisements and sponsorships across our Web site. As of
December 31, 1999, our sales organization was comprised of six employees and
one consultant engaged in direct selling efforts.

Competition

    Our competitors fall into four primary categories:

  .   traditional and online white and yellow pages information providers;

  .   companies providing Web-enabled solutions for small businesses;

  .   companies targeting consumers seeking local information; and

  .   companies targeting the consumer Internet services market.

    We compete in the markets for Internet content, services and advertising.
These markets are highly competitive and we expect competition to increase in
the future with the entrance of new competitors. Currently, the number of
companies aggregating small businesses and providing them with a similar
comprehensive solution and scale is small. However, the market is rapidly
developing. Barriers to entry in these markets are not significant and current
and new competitors may be able to launch new Web sites at a relatively low
cost.

    We believe our ability to compete successfully depends on many factors,
several of which are outside of our control. These factors include the quality
of content we provide relative to our competitors, the cost-effectiveness and
reliability of our services relative to our competitors and our ability to
generate leads for merchants.

    We also compete with traditional advertising media, including television,
radio and print, for a share of advertisers' total advertising budgets. If
advertisers consider the Internet, or our site, to be a limited or ineffective
advertising medium, advertisers may be reluctant to devote a significant amount
of their advertising dollars to advertising on our Web site.

Intellectual Property

    We regard our patents, copyrights, service marks, trademarks, trade dress,
trade secrets and other intellectual property as critical to our success. We
rely on a combination of patent, trademark and copyright law, trade secret
protection and confidentiality and/or license agreements with our employees,
consultants, customers, partners and others to protect our proprietary rights.
All of our employees have executed confidentiality and assignment of invention
agreements. Prior to disclosing confidential information to third parties, we
generally require them to sign confidentiality or other agreements restricting
the use and disclosure of our confidential information.

                                       45
<PAGE>


    As of December 31, 1999, we had four patents issued by the U.S. Patent and
Trademark Office and three patent applications pending before the Canadian
Intellectual Property Office, all of which relate to the operation, features or
performance of our Web site. We pursue registration of our key trademarks and
service marks in the United States and, in some cases, internationally.
However, effective trademark, service mark, copyright and trade secret
protection may not be available or sought by us in every country in which our
services are made available online. Our patents, trademarks, or other
intellectual property rights may be successfully challenged by others or
invalidated through administrative process or litigation. Further, the
validity, enforceability and scope of protection of proprietary rights in
Internet-related industries is uncertain and still evolving.

    We license our proprietary rights, such as patents, trademarks and
copyrighted material, to third parties. Despite our efforts to protect our
proprietary rights, third parties may infringe or misappropriate our rights or
diminish the quality or reputation associated with our brand, which could have
a material adverse affect on our business, results of operations, or financial
condition.

    In addition, we license software, content and other intellectual property,
including trademarks, patents, and copyrighted material, from third parties. In
particular, we license the rights to use the "CBS" trademark and "eye" device
under a license with CBS which expires by its terms in June 2009. We also
license residential and business listing data from infoUSA, Inc. under an
agreement that expires in December 2002, and maps and driving directions data
and related software from Etak, Inc. under an agreement that expires in
November 2000. Further, the software code underlying Switchboard.com contains
software code which is licensed to us by third parties. If any of these
licenses are terminated or expire, it could have a material adverse effect on
our business, results of operations or financial condition.

    We currently own a number of Internet domain names, including
Switchboard.com, MapsOnUs.com and SideClick.com. In addition, we co-own with
CBS the domain names CBS.Switchboard.com and CBSSwitchboard.com. Domain names
generally are regulated by Internet regulatory bodies. The relationship between
regulations governing domain names and laws protecting trademarks and similar
proprietary rights is unclear. We therefore, could be unable to prevent third
parties from acquiring domain names that infringe or otherwise decrease the
value of our trademarks and other proprietary rights.

Employees

    As of December 31, 1999, we had 52 full-time employees. None of our
employees is represented by a labor union. We believe our relations with our
employees are good.

Facilities

    Our headquarters are located in Westboro, Massachusetts, where we occupy
approximately 8,000 square feet under an agreement with Banyan Worldwide. Since
our inception through December 31, 1999 we have incurred expenses of $552,121
under an agreement with Banyan Worldwide relating to facilities fees, which
cover rent and costs of furnishings, equipment, telephone service, security in
our building, the fitness center, shared cafeteria costs and building
maintenance.

    Our agreement with Banyan Worldwide continues in effect until November 2000
and renews on a year-to-year basis each November unless we or Banyan Worldwide
terminate the agreement upon 90 days' written notice. Upon the completion of
this offering, we intend to enter into a new sublease with Banyan Worldwide
which, together with a new services agreement we intend to enter into with
Banyan Worldwide, will replace our existing agreement with Banyan Worldwide.
The new sublease will terminate on December 31, 2002, but we will have the
option to extend the term to September 30, 2005. Our monthly rent under the new
sublease will be $25,551. We believe our facilities will be adequate for our
anticipated growth and that we will be able to obtain additional space as
needed on commercially reasonable terms.

Legal Proceedings

    We are not currently subject to any material legal proceedings. From time
to time, we are involved in various legal proceedings incidental to the conduct
of our business.

Option Grants in Last Fiscal Year

    The following table contains information concerning the stock option grants
made to each of the Named Executive Officers in 1999. Unless otherwise noted,
each stock option grant vests in four equal installments beginning one year
after the date of grant and has a term of ten years. The per share exercise
price of all options granted to our Named Executive Officers represents the
fair market value of our common stock on the grant date.

    Amounts described in the following table under the heading "Potential
Realizable Value at Assumed Rates of Stock Price Appreciation for Option Term"
represent hypothetical gains that could be achieved for the options if
exercised at the end of the option term. These gains are based on assumed rates
of stock appreciation of 5% and 10% compounded annually from the date the
options were granted to their expiration date. Actual gains, if any, on stock
option exercises will depend on the future performance of the common stock and
the date on which the options are exercised. No gain to the optionees is
possible without an appreciation in stock price, which will benefit all
stockholders commensurately.

Fiscal Year-End Option Values

    None of our Named Executive Officers exercised stock options in the fiscal
year ended December 31, 1999. The following table sets forth information
concerning the number and value of unexercised options held by each of our
Named Executive Officers on December 31, 1999. There was no public market for
our common stock as of December 31, 1999. Accordingly, the fair market value on
December 31, 1999 is based on an assumed initial public offering price of
$11.00 per share.

Benefit Plans

 1996 Stock Incentive Plan

    Our 1996 stock incentive plan was adopted by our board of directors and
approved by our stockholders in September 1996. The 1996 plan authorizes the
issuance of up to 3,000,000 shares of our common stock. As of December 31,
1999, options to purchase an aggregate of 2,944,600 shares of our common stock
at a weighted average exercise price of $6.22 per share were outstanding under
the 1996 plan. Upon the closing of this offering, no additional grants of stock
options or other awards will be made under the 1996 plan.

                                       51
<PAGE>

 1999 Stock Incentive Plan

    Up to 1,875,000 shares of our common stock (subject to adjustment in the
event of stock splits and other similar events) may be issued pursuant to
awards granted under our 1999 stock incentive plan. The 1999 plan is intended
to replace our 1996 plan. The 1999 plan provides for the grant of incentive
stock options intended to qualify under Section 422 of the Internal Revenue
Code, nonstatutory stock options, restricted stock awards and other stock-based
awards. The granting of awards under the 1999 plan is discretionary. As of
December 31, 1999, options to purchase an aggregate of 7,000 shares of our
common stock at a weighted average exercise price of $9.00 per share were
outstanding under the 1999 plan.

    Our officers, employees, directors, consultants and advisors and those of
our subsidiaries are eligible to receive awards under the 1999 plan. Under
present law, however, incentive stock options may only be granted to employees.
No participant may receive any award for more than 1,000,000 shares in any
calendar year. As of December 31, 1999, approximately 59 persons would have
been eligible to receive awards under the 1999 plan, including three executive
officers and six non-employee directors.

    Optionees receive the right to purchase a specified number of shares of our
common stock at a specified option price and subject to other terms and
conditions specified in connection with the option grant. We may grant options
at an exercise price less than, equal to or greater than the fair market value
of our common stock on the date of grant. Under present law, incentive stock
options and options intended to qualify as performance-based compensation under
Section 162(m) of the Internal Revenue 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
Switchboard. The 1999 plan permits our board of directors to determine how
optionees may pay the exercise price of their options, including by cash, check
or in connection with a "cashless exercise" through a broker, by surrender to
us of shares of common stock, by delivery to us of a promissory note, or by any
combination of the permitted forms of payment.

    Our board of directors administers the 1999 plan. Our board of directors
has the authority to adopt, amend and repeal the administrative rules,
guidelines and practices relating to the plan and to interpret its provisions.
It may delegate authority under the 1999 plan to one or more committees of the
board of directors. Subject to any applicable limitations contained in the 1999
plan, our board of directors or a committee of the board of directors or
executive officer to whom our board of directors delegates authority, as the
case may be, selects the recipients of awards and determines:

  .   the number of shares of common stock covered by options and the dates
      upon which options become exercisable;

  .   the exercise price of options;

  .   the duration of options; and

  .   the number of shares of common stock subject to any restricted stock or
      other stock-based awards and the terms and conditions of the awards,
      including the conditions for repurchase, issue price and repurchase
      price.

    In the event of a merger, liquidation or other acquisition event, our board
of directors is authorized to provide for outstanding options or other stock-
based awards to be assumed or substituted for by the acquiror. If the acquiror
refuses to assume or substitute for outstanding options, they will accelerate
in part, becoming exercisable with respect to 50% of the unvested portion of
the options, prior to consummation of the acquisition event.

    No award may be granted under the 1999 plan after October 2009, but the
vesting and effectiveness of awards previously granted may extend beyond that
date. Our board of directors may at any time amend, suspend or terminate the
1999 plan, except that no award granted after an amendment of the 1999 plan and
designated as subject to Section 162(m) of the Internal Revenue Code by our
board of directors shall become exercisable, realizable or vested, to the
extent the amendment was required to grant the award, unless and until the
amendment is approved by our stockholders.

 1999 Employee Stock Purchase Plan

    Under our 1999 employee stock purchase plan, up to a total of 300,000
shares of our common stock may be issued to participating employees.

    The following employees, including our directors who are employees and
employees of any participating subsidiaries, are eligible to participate in the
purchase plan:

  .   Employees who are customarily employed for more than 20 hours per week
      and for more than five months per year; and

  .   Employees employed for at least three months prior to enrolling in the
      purchase plan.

    Employees who would immediately after the grant own 5% or more of the total
combined voting power or value of our stock or any subsidiary are not eligible
to participate. As of December 31, 1999, approximately 43 of our employees
would have been eligible to participate in the purchase plan.

    On the first day of a designated payroll deduction period, or "offering
period", we will grant to each eligible employee who has elected to participate
in the purchase plan an option to purchase shares of our common stock as
follows: the employee may authorize between 1% to 10% of his or her base pay to
be deducted by us from his or her base pay during the offering period. On the
last day of this offering period, the employee is deemed to have exercised the
option, at the option exercise price, to the extent of accumulated payroll
deductions. Under the terms of the purchase plan, the option price is an amount
equal to 85% of the per share closing price of our common stock on either the
first day or the last day of the offering period, whichever is lower. No
employee may be granted an option which would allow their rights to purchase
our common stock to accrue at a rate which exceeds $25,000 of the fair market
value of that stock, determined on the first day of the offering period, for
each calendar year in which the option is outstanding. The board of directors
will choose the timing and length of offering periods under the purchase plan.

    An employee who is not a participant on the last day of the offering period
is not entitled to exercise any option, and the employee's accumulated payroll
deductions will be refunded. An employee's rights under the purchase plan
terminate upon voluntary withdrawal from the purchase plan at any time, or when
the employee ceases employment for any reason.


Employment Agreements

 Douglas J. Greenlaw

    In October 1999, we entered into an employment agreement with Douglas J.
Greenlaw, our Chief Executive Officer. Mr. Greenlaw will receive an annual base
salary of $225,000 and is eligible to receive an annual performance bonus
targeted at $75,000, based upon a combination of our performance and Mr.
Greenlaw's achievement of individual objectives. In addition, we provide Mr.
Greenlaw with executive life insurance at a value equal to five times his base
salary. Mr. Greenlaw also received non-qualified options to purchase up to
900,000 shares of our common stock at an exercise price of $9.00 per share
which will vest according to the following schedule:

  .   150,000 will vest after each of the first, second, third and fourth
      years of employment; and

  .   300,000 will vest after the fifth year of employment.

The vesting of the 150,000 shares to vest after each of the third and fourth
years of Mr. Greenlaw's employment and the vesting of 200,000 shares to vest
after the fifth year of Mr. Greenlaw's employment will accelerate if and when
Switchboard achieves a market capitalization for 90 consecutive days of $1.0
billion with respect to the third year options, for 90 consecutive days of $1.5
billion for the fourth year options and for 180 consecutive days of $2.0
billion for the fifth year options. In addition, the vesting of the remaining
100,000 shares to vest after the fifth year of Mr. Greenlaw's employment
accelerates upon the completion of this offering.

                                       53
<PAGE>


    If a change in control of Switchboard occurs, the vesting of 50% of any
unvested portion of Mr. Greenlaw's options acclerates. One year after a change
in control of Switchboard, the vesting of 100% of the then unvested portion of
Mr. Greenlaw's options accelerates. If we terminate Mr. Greenlaw's employment
within one year of a change in control or if we materially reduce his
responsibilities from those in effect immediately prior to a change in control,
the vesting of 100% of the then unvested portion of his options accelerates. If
we terminate Mr. Greenlaw's employment for any reason, except for cause, Mr.
Greenlaw will be entitled to:

  .   his base salary and bonus, pro rated for assumed on-target achievement
      of performance objectives, for six months from the date of termination;
      and

  .   continued employee benefits coverage for six months.

 Dean Polnerow

    In December 1999, we entered into an employment agreement with Dean
Polnerow, our President, under which Mr. Polnerow will receive an annual salary
of $165,000 and is eligible to receive an annual performance bonus targeted at
$60,000. Mr. Polnerow may earn an additional $35,000 for overachievement of
specified goals. In addition, we provide Mr. Polnerow with executive life
insurance at a value equal to five times his base salary. The term of Mr.
Polnerow's agreement is for one year and renews automatically for successive
one year periods unless either party provides 60 days' written notice of its
intent not to renew.

    Since January 1997, we have granted options to Mr. Polnerow to purchase up
to an aggregate of 435,000 shares of our common stock at a weighted average
exercise price of $4.42 per share. Of these options:

  .   250,000 of these options vest over a four-year period of continuous
      employment, with 25% vesting each year;

  .   40,000 of these options vest over a four-year period of continuous
      employment, with zero vesting after the first year, 25% vesting after
      the second year, 25% vesting after the third year and 50% vesting after
      the fourth year; and

  .   145,000 of these options vest over a five-year period of continuous
      employment, with 35,000 vesting after the second year, 35,000 vesting
      after the third year, 50,000 vesting after the fourth year and 25,000
      shares vesting after the fifth year; provided, that, the vesting of the
      35,000 shares to vest after the second and third years and the 50,000
      shares to vest after the fourth year will accelerate if and when
      Switchboard achieves a market capitalization for 90 consecutive days of
      $1.0 billion with respect to the second year options, for 90
      consecutive days of $1.5 billion with respect to the third year
      options, and for 180 consecutive days of $2.0 billion with respect to
      the fourth year options, and the vesting of the 25,000 shares to vest
      after the fifth year accelerates upon the completion of this offering.

    If Mr. Polnerow remains employed by us for six months after a change in
control, or if within six months after a change in control Mr. Polnerow resigns
because we have relocated him to an office more than 35 miles from Westboro,
Massachusetts or because we have materially reduced his compensation or
responsibilities from those in effect immediately prior to the change in
control, 50% of any unvested portion of his options accelerates. If we
terminate Mr. Polnerow's employment within one year of a change in control of
Switchboard other than for cause, the vesting of 100% of the then unvested
portion of his options accelerates. If we terminate Mr. Polnerow's employment
for any reason, except for cause, or if Mr. Polnerow resigns within 90 days
after we relocate Mr. Polnerow to an office more than 35 miles from Westboro,
Massachusetts or after we materially reduce his job title and/or overall
targeted cash compensation from those in effect at the beginning of his
employment agreement, Mr. Polnerow will be entitled to:

  .   his base salary and bonus, pro rated for assumed on-target achievement
      of performance objectives, for six months from the date of termination;
      and

  .   continued employee benefits coverage for six months.

                                       54
<PAGE>

 John P. Jewett

    In January 2000, we entered into an employment agreement with
John P. Jewett, our Vice President, Finance and Administration and Chief
Financial Officer, under which Mr. Jewett will receive an annual salary of
$125,000 and is eligible to receive an annual performance bonus targeted at
$55,000, each as may be adjusted from time to time in the discretion of our
board of directors. The term of Mr. Jewett's agreement is for one year and
renews automatically for successive one year periods unless either party
provides 60 days' written notice of its intent not to renew.

    Since October 1998, we have granted options to Mr. Jewett to purchase up to
an aggregate of 150,000 shares of our common stock at a weighted average
exercise price of $4.66 per share. Of these options, 100,000 vest over a four-
year period, with 25% vesting after each year of employment. 20,000 of these
options vested on an accelerated basis in June 1999 upon the achievement of
specified objectives. The remaining 50,000 of Mr. Jewett's options vest
according to the following schedule:

  .   12,500 of these options will vest after each of the second and third
      years of continuous employment;

  .   15,000 of these options will vest after the fourth year of continuous
      employment; and

  .   10,000 of these options will vest after the fifth year of continuous
      employment.

The vesting of the 12,500 shares to vest after each of the second and third
years of continuous employment and the vesting of the 15,000 shares after the
fourth year of continuous employment will accelerate if and when Switchboard
achieves a market capitalization for 90 consecutive days of $1.0 billion with
respect to the second year options, for 90 consecutive days of $1.5 billion
with respect to the third year options and for 180 consecutive days of $2.0
billion with respect to the fourth year options. In addition, the vesting of
the 10,000 shares to vest after the fifth year of continuous employment
accelerates upon the completion of this offering.

    If Mr. Jewett remains employed by us for six months after a change in
control, or if within six months after a change in control Mr. Jewett resigns
because we have materially reduced his job title and/or overall targeted cash
compensation from those in effect immediately prior to the change in control,
50% of any unvested portion of his options accelerate. If we terminate Mr.
Jewett's employment for any reason, except for cause, or if Mr. Jewett resigns
within 90 days after we materially reduce his job title and/or overall targeted
cash compensation from those in effect at the beginning of his employment
agreement, Mr. Jewett will be entitled to:

  .   his base salary for six months from the date of termination, or, if he
      obtains employment elsewhere at a lower salary, he will receive the
      difference in salary for six months; and

  .   continued employee benefits coverage for six months.

 James M. Canon

    In December 1999, we entered into an employment agreement with James M.
Canon, our Vice President, Business Development, under which Mr. Canon receives
an annual salary of $130,000 and is eligible to receive an annual performance
bonus targeted at $32,500. The term of Mr. Canon's agreement is for one year
and renews automatically for successive one year periods unless either party
provides 60 days' written notice of its intent not to renew.

    Since June 1996, we have granted options to Mr. Canon to purchase up to an
aggregate of 250,000 shares of our common stock, at a weighted average exercise
price of $3.24 per share. These options vest according to the following
schedule:

  .   180,000 vest over a four-year period of continuous employment, with 25%
      vesting after each year;

  .   20,000 of these options vest over a four-year period of continuous
      employment, with zero vesting after the first year, 25% vesting after
      the second year, 25% vesting after the third year and 50% vesting after
      the fourth year; and

                                       55
<PAGE>

  .   50,000 of these options vest over a five-year period of continuous
      employment, with 12,500 vesting after the second year, 12,500 vesting
      after the third year, 15,000 vesting after the fourth year and 10,000
      vesting after the fifth year; provided, that, the vesting of the 12,500
      shares to vest after the second and third years and the 15,000 shares
      to vest after the fourth year will accelerate if and when Switchboard
      achieves a market capitalization for 90 consecutive days of $1.0
      billion with respect to the second year options, for 90 consecutive
      days of $1.5 billion with respect to the third year options, and for
      180 consecutive days of $2.0 billion with respect to the fourth year
      options and the vesting of the 10,000 shares after the fifth year
      accelerates upon the completion of this offering.

    If Mr. Canon remains employed by us for six months after a change in
control, or if within six months after a change in control Mr. Canon resigns
because we have relocated him to an office more than 35 miles from Westboro,
Massachusetts or because we have materially reduced his compensation or
responsibilities from those in effect immediately prior to the change in
control, 50% of any unvested portion of his options accelerates. If we
terminate Mr. Canon's employment for any reason, except for cause, or if Mr.
Canon resigns within 90 days after we relocate Mr. Canon to an office more than
35 miles from Westboro, Massachusetts or after we materially reduce his job
title and/or overall targeted cash compensation from those in effect at the
beginning of his employment agreement, Mr. Canon will be entitled to:

  .   his base salary for six months from the date of termination, or, if he
      obtains employment elsewhere at a lower salary, he will receive the
      difference in salary for six months; and

  .   continued employee benefits coverage for six months.

                              CERTAIN TRANSACTIONS

Banyan Worldwide

 Formation and Initial Issuances of Securities

    We were incorporated in April 1996 as a wholly owned subsidiary of Banyan
Worldwide. In connection with our formation, we issued ten shares of our common
stock to Banyan Worldwide for nominal consideration. In November 1996, we
issued 6,999,990 shares of our common stock to Banyan Worldwide, our sole
stockholder at the time, in consideration for the transfer by Banyan Worldwide
to us of our core technologies and net assets valued at approximately $546,000
and in settlement of advances from Banyan Worldwide of approximately $697,000.

 Secured Convertible Note Facilities

    1997 Note Facility. On August 29, 1997, we entered into a secured
convertible note facility with Banyan Worldwide. The facility was initially for
$3.0 million, and was increased on February 20, 1998 to $7.0 million and on May
3, 1999 to $10.0 million. Outstanding amounts under the facility bore interest
at the applicable federal rate under Section 1274 of the Internal Revenue Code
for short-term loans with annual compounding of interest for the month in which
a loan was made. The outstanding amount of principal and interest was
convertible at the option of Banyan Worldwide into shares of our series C
preferred stock at a rate of $4.00 per share at any time. On June 30, 1999, we
issued 2,655,916 shares of our series C convertible preferred stock to Banyan
Worldwide upon the conversion of principal and interest of $10,623,664 under
this note. The dollar amount converted represented all of the principal and
interest outstanding as of June 30, 1999, the date on which we first issued our
securities to CBS. This conversion was made by Banyan Worldwide to satisfy a
condition to completing the transactions with CBS that required Banyan
Worldwide to convert all outstanding indebtedness under convertible secured
notes. After this conversion, we are no longer able to borrow any amounts under
this facility.

    1999 Note Facility. On May 3, 1999, we entered into a second secured
convertible note facility with Banyan Worldwide. This facility was subsequently
amended and restated in its entirety on January 26, 2000. This facility was
originally for $5.0 million. Outstanding amounts bear interest at the
applicable federal rate under Section 1274 of the Internal Revenue Code for
short-term loans with annual compounding of interest for the month in which
such loan is made. The outstanding amount of principal and interest is
convertible at the option of Banyan Worldwide into shares of our series D
preferred stock at any time prior to this offering. Outstanding amounts are
convertible at a rate of $11.00 per share. That conversion rate is subject to
adjustment in the event Switchboard sells equity securities or engages in a
capital raising transaction, including this offering, or any other transaction
material to the Company, based upon the per share fair market value of the
series D preferred stock immediately following that transaction, as determined
in good faith by Switchboard and Banyan Worldwide. The conversion rate is also
subject to adjustment in the event of stock dividends, reclassifications, stock
splits and other similar transactions on the series D preferred stock.

    On June 30, 1999, we issued 87,345 shares of our series D preferred stock
to Banyan Worldwide upon the conversion by Banyan Worldwide of principal and
interest of $655,089 under this note. The dollar amount converted represented
an estimate of all of the principal and interest outstanding as of June 30,
1999. As of July 1, 1999, we issued 59,160 additional shares of our series D
preferred stock to Banyan Worldwide upon the conversion by Banyan Worldwide of
principal and interest of $443,699 under this note. The dollar amount converted
represented the actual amount of all of the principal and interest outstanding
as of June 30, 1999, after giving effect to the estimate we made on June 30,
1999. This conversion was made by Banyan Worldwide to put Banyan Worldwide and
CBS in the equity ownership position they would have been in had the actual
amount of outstanding principal and interest at June 30, 1999 been known on
June 30, 1999. The conversion rate at the time of these conversions was $7.50
per share.

    This facility remains in place and the maximum remaining amount we may
borrow under the facility was approximately $3.9 million, as of December 31,
1999. As of December 31, 1999 there were no amounts

                                       57

outstanding under the facility. Upon the completion of this offering, this
facility will automatically terminate in full and any outstanding principal and
interest will be converted into shares of our series D preferred stock at the
then-applicable conversion rate. Any shares of our Series D preferred stock
which are issued will convert automatically into shares of common stock upon
completion of this offering.

 Officers and Directors

    Our Chairman of the Board of Directors, William P. Ferry, is Chairman of
the Board of Directors, President and Chief Executive Officer of Banyan
Worldwide. Our director Robert M. Wadsworth is also a director of Banyan
Worldwide. David N. Strohm, another of our directors, served as a director of
Banyan Worldwide from 1983 until November 1999. Our director Richard M.
Spaulding is Vice President and Chief Financial Officer of Banyan Worldwide.

 Corporate Services Agreements

    We are party to a corporate services agreement with Banyan Worldwide. Under
this agreement, we currently pay Banyan Worldwide a fixed monthly fee of
approximately $41,000 for facilities, utilities, maintenance and various
administrative and other services. These services include:

  .   financial and accounting advice;

  .   human resources advice and routine related services;

  .   payroll advice and routine related services;

  .   treasury, insurance and tax services; and

  .   routine data processing, technical support and equipment maintenance
      services.

    At our request, Banyan Worldwide will also provide us with other services
for an additional charge based on Banyan Worldwide's labor costs, including
benefits, for the applicable Banyan Worldwide employee performing the services.
These services include:

  .   development of data processing systems and programs;

  .   legal support, including patent prosecution;

  .   support in financing and acquisition transactions;

  .   general executive and management services; and

  .   support for contract bidding and other proposals.

In addition, we reimburse Banyan Worldwide for our pro rata share of telephone,
photocopying and postage expenses and our pro rata share of Banyan Worldwide's
expenses relating to our participation in its employee benefits plans.

    Beginning in November 1999, this corporate services agreement renews
annually unless either party terminates the agreement with 90 days' notice to
the other. Our total expense to Banyan Worldwide under the corporate services
agreement through December 31, 1999 was approximately $1,382,990.

    Upon the completion of this offering, we intend to enter into a new
services agreement with Banyan Worldwide which will replace our current
services agreement. Under the new services agreement, we will pay Banyan
Worldwide an aggregate annual fee of $200,000 in 12 monthly installments, and
Banyan Worldwide will provide us with information technology services,
including physical infrastructure, workstation and applications support,
communications and other consulting services. The agreement will have an
initial term of one year.

    In connection with the new services agreement, and also upon completion of
this offering, we intend to enter into a new sublease with Banyan Worldwide of
our facilities in Westboro, Massachusetts. Under the new sublease, we will pay
monthly rent to Banyan Worldwide in the amount of $25,551. The sublease will
terminate on December 31, 2002 and we will have the option to extend the term
of the sublease to September 30, 2005.

                                       58

 Indemnification

    Banyan Worldwide is a party to our advertising and promotion agreement with
CBS. As part of the advertising and promotion agreement, Banyan Worldwide
agreed to indemnify CBS for any breach by us of our representations, warranties
or covenants in the agreement. Banyan Worldwide's indemnification obligations
with respect to our covenants will expire upon the first to occur of:

  .   the first business day after June 30, 2001 when Banyan Worldwide owns
      or controls less than a majority of our voting power; and

  .   the first business day after any person owns or controls more of our
      voting power than Banyan Worldwide does.

    We have agreed to indemnify Banyan Worldwide for amounts that Banyan
Worldwide may be required to pay to CBS pursuant to Banyan Worldwide's
indemnification obligations to CBS.

CBS Corporation

 Issuances of Securities

    We have issued the following securities to CBS:

  .   7,468,560 shares of our common stock;

  .   one share of our series E special voting preferred stock; and

  .   warrants to purchase 1,066,937 shares of our common stock.

    The warrants are exercisable from the date of the closing of this offering
until the second anniversary of that date at an exercise price of $1.00 per
share. The exercise price and number of shares for which the warrants may be
exercised are subject to adjustment if we issue shares of our common stock at
less than $16.00 per share other than pursuant to the following:

  .   the conversion, exchange or exercise of securities that were
      outstanding on June 30, 1999;

  .   a dividend, stock split, split-up or other distribution on shares of
      common stock which results in an adjustment of the exercise price under
      the provisions of the warrant addressing recapitalizations, mergers or
      other such events;

  .   this offering; and

  .   any lending or line of credit arrangement with Banyan Worldwide that
      existed on June 30, 1999.

    In addition, we are permitted to issue at less than $16.00 per share up to
4,000,000 shares of our common stock to our employees, directors, consultants
or advisors and up to 100,000 shares of our common stock in connection with
future borrowings or financings, or for any other purpose, in each case without
adjusting the exercise price of the warrant. The exercise price and the number
of shares for which the warrants may be exercised and the $16.00 per share
amount referred to in the two prior sentences are also subject to adjustment in
the event of a stock split, stock dividend, reverse stock split, capital
reorganization or reclassification, consolidation or merger of Switchboard into
another corporation or a transfer of our assets.

    The number of shares of common stock and warrants issued to CBS was
calculated so that CBS would acquire shares of common stock equaling 35% of our
fully diluted common stock and warrants to acquire another 5% of our fully
diluted common stock. We made assumptions in determining what our fully diluted
capital stock was and agreed to increase the number of shares and warrants
issued to CBS if those assumptions turn out to be incorrect. If we issue any
shares pursuant to the series B convertible preferred stock purchase warrant
originally issued to America Online, which we believe has expired pursuant to
its terms, we are required to issue to CBS, within ten business days and for no
additional consideration, the additional number of shares of common stock and
warrants to purchase common stock that would have been issued to CBS on
June 30, 1999 had we included the series B convertible preferred stock warrant
in our calculations.

                                       59

 Voting Rights and Directors

    We issued one share of our series E special voting preferred stock to CBS.
This share, which will remain outstanding after this offering, entitles CBS to
elect that number of members of our board of directors, rounded down to the
nearest whole number, as equals CBS's fully diluted ownership percentage of
our securities. Currently, this means that CBS can designate two of our nine
director positions. The number of directors determined by this formula may not
be less than one at any time when the license agreement is in effect and may
not be greater than the maximum number which would constitute a minority of
our board of directors. In addition, even if CBS does not own any other of our
securities, they are entitled to elect one director so long as the license
agreement is in effect. The special voting rights of the series E preferred
stock terminate upon the first to occur of:

  .   the date on which CBS no longer owns any of our securities and the
      license agreement is no longer in effect;

  .   the date on which a competitor of Switchboard owns more than 30% of the
      common stock or securities representing more than 30% of the voting
      power of CBS; and

  .   the date on which the share of series E preferred stock is owned by a
      person other than CBS or an entity controlling, controlled by or under
      common control with CBS.

    Our directors, Daniel Mason, Executive Vice President of Infinity
Broadcasting Corporation, a majority-owned subsidiary of CBS, and Russell I.
Pillar, President and Chief Executive Officer of CBS Internet Group, a
division of CBS, were elected to our board of directors under the rights of
the series E preferred stock described above.

 License Agreement

    On June 30, 1999, we entered into a license agreement with CBS. Under the
license agreement, CBS granted us a non-exclusive license to use the "CBS"
trademark and "eye" device together with the Switchboard mark to identify,
market and promote our Web site. Under the agreement, CBS will retain approval
rights over the use and presentation of its trademarks. For example:

  .   our use of the CBS trademarks must conform to CBS's guidelines, which
      may be changed from time to time by CBS;

  .   each use of the CBS trademarks in connection with our marketing or
      promotional materials requires obtaining CBS's prior written approval;
      and

  .   CBS may require us to remove from our Web site any content that CBS
      determines conflicts with, or interferes with or is detrimental to
      CBS's interests, reputation or business or which might subject CBS to
      legal liability or regulatory action.

    The license agreement also places restrictions on our rights to accept
advertising from competitors of CBS.

    During the term of the license agreement, CBS may not license the CBS
trademarks in connection with naming or promoting in the United States any
Internet site that has as its primary function and theme the delivery of
directory information for residential listings, business listings, email
addresses or Web sites. This restriction does not apply to:

  .   any activity conducted by CBS as of June 30, 1999;

  .   any activity conducted by CBS television or radio affiliates that are
      not CBS owned or operated;

  .   any Internet services or Web sites in which CBS had an equity interest
      as of June 30, 1999; and

  .   the use of any CBS trademarks to identify CBS as the source of any
      content.

                                      60
<PAGE>

    The license agreement expires on June 30, 2009. CBS may terminate the
agreement before the end of its term if:

  .   we breach any material term of the license agreement;

  .   we or Banyan Worldwide breach any material term of the advertising and
      promotion agreement, the common stock and warrant purchase agreement,
      the right of first refusal agreement, the stockholders' voting
      agreement, or the registration rights agreement that we entered into
      with CBS;

  .   we become insolvent or commence or become subject to bankruptcy or
      similar proceedings;

  .   we issue to a CBS competitor or assist a CBS competitor in acquiring 9%
      or more of our common stock or total voting power; or

  .   any CBS competitor owns or controls 15% or more of our common stock or
      total voting power.

    In the event of a breach by CBS of a material term of the license agreement
or the advertising and promotion agreement, we may terminate the license
agreement. If we so terminate the license agreement, CBS will pay us $3.5
million for each year that was remaining under the term of the agreement, pro
rated for any partial year.

    The agreement provides for the joint ownership of domain names for the
Switchboard Web site featuring both the "CBS" and "Switchboard" trademarks and
contains provisions governing the use of those domain names following any
termination or expiration of the license agreement.

 Advertising and Promotion Agreement

    On June 30, 1999, we entered into an advertising and promotion agreement
with CBS. Over the term of the advertising and promotion agreement, CBS will
arrange for the placement of up to $95.0 million worth of advertising and
promotion of our Web site.

    CBS's advertising and promotion commitment is divided into seven one-year
periods during the term of the agreement. CBS's commitment during the first
three years of the agreement is $13.0 million per year and during the last four
years of the agreement is $14.0 million per year. We may carry forward to a
subsequent period up to 35% of the advertising value to which we are entitled
during any one-year period. However, CBS is not obligated to provide
advertising value aggregating more than $18.9 million during any one-year
period. The value of advertising and promotion services provided by CBS is
generally determined by reference to the average price paid by others to CBS
for comparable advertising and promotion.

    All our advertising is subject to CBS's advertising guidelines and
preemption policies and CBS is not required to make any ad placements if the
exigencies of time or contractual obligations prevent or restrict CBS from
doing so. CBS may suspend advertising for us:

  .   if at any time in the future a claim arises regarding our right to use
      the Switchboard trademark; or

  .   in the event our Web site is not operational for a 48-hour period,
      until it becomes operational again consistent with operations prior to
      the disruption.

    Under the agreement, CBS has the right to sell advertising on our Web site
and co-branded Web pages. We will pay CBS a commission for any sales by CBS.

    In addition, CBS has agreed to place links to our Web site on CBS
controlled Web sites and to use good faith efforts to obtain similar links on
other Web sites in which CBS has a non-controlling interest. We will pay CBS a
percentage of net revenue derived from Web pages displayed through those links
which include both CBS and Switchboard trademarks. We and CBS have also agreed
to work together in good faith during the term of the agreement to identify
other opportunities to integrate our directory features into CBS's Web sites
and to integrate local content from CBS's Web site into our Web site.

    The advertising and promotion agreement expires on June 30, 2006. CBS may
terminate the agreement before the end of its term if:

                                       61
<PAGE>

  .   we or Banyan Worldwide breach any material term of the advertising and
      promotion agreement, the license agreement, the common stock and
      warrant purchase agreement, the right of first refusal agreement, the
      stockholders' voting agreement, or the registration rights agreement
      that we entered into with CBS;

  .   we become insolvent or commence or become subject to bankruptcy or
      similar proceedings;

  .   we issue to a CBS competitor or assist a CBS competitor in acquiring 9%
      or more of our common stock or total voting power;

  .   any CBS competitor owns or controls 15% or more of our common stock or
      total voting power;

  .   we discontinue using the "Switchboard" trademark and fail to establish
      a substitute mark acceptable to CBS;

  .   our license agreement with CBS is terminated or expires; or

  .   our Web site ceases to operate for specified periods of time.

    In the event of a breach by CBS of a material term of the advertising and
promotion agreement or the license agreement that is not cured within 30 days
after receipt of our notice, we may terminate the advertising and promotion
agreement. If we so terminate the advertising and promotion agreement, CBS's
obligation to provide advertising and promotion would continue unless CBS
elects to pay us, over the remaining scheduled term of the agreement or in a
lump sum payment, the present value cash equivalent of the difference between
$95.0 million and the value of advertising and promotion already provided to
us.

    The advertising and promotion agreement also provides that, if a CBS
competitor acquires a 30% or more interest in Banyan Worldwide or all or
substantially all of Banyan Worldwide's assets at a time when Banyan Worldwide
owns 10% or more of our common stock, then CBS has the right to purchase Banyan
Worldwide's shares of our capital stock or require that those shares be
transferred to an independent trustee for sale to a third party. If CBS were to
exercise this right, a change of control of Switchboard may occur.

    We have agreed with CBS that we will use our reasonable best efforts to
adhere to performance standards for our Web site, including to:

  .   maintain availability of our Web site seven days a week, 24 hours a
      day, other than during periods of scheduled maintenance;

  .   maintain 97% uptime over a 12 month period for our Web site and the co-
      branded interfaces we display to users, barring events that are beyond
      our control;

  .   maintain competitive standards of quality and ease of use with those
      offered by other leading Internet-based directory services; and

  . achieve specified response times to user inquiries.

 Common Stock and Warrant Purchase Agreement and Other Equity Agreements

    The common stock, series E preferred stock and warrants described above
were issued to CBS pursuant to a purchase agreement dated June 1, 1999. We and
Banyan Worldwide indemnify CBS for breaches of representations and warranties
under the purchase agreement.

    On June 30, 1999, we entered into a series of equity-related agreements
with CBS:

  .   Right of First Refusal Agreement. This agreement restricts CBS's right
      to transfer its shares of our common stock. Under this agreement:

    .   prior to the first anniversary of this offering, if CBS wishes to
        sell any of its shares of our common stock it must first offer them
        to us and then to Banyan Worldwide; and

    .   prior to June 30, 2001, if the license agreement or the advertising
        and promotion agreement has terminated for any reason and CBS
        wishes to sell any of its shares of our common stock, we have a
        right of first refusal to buy those shares on the same terms that a
        third party identified by CBS has offered to buy the shares and
        Banyan Worldwide has a right of first refusal if we do not first
        exercise our right.

                                       62
<PAGE>


  .   Participation Agreement. Under this agreement we agreed to use our
      reasonable best efforts to issue and sell to CBS and Banyan Worldwide,
      simultaneously with the closing of this offering, additional shares of
      our common stock so that each of CBS and Banyan Worldwide could own
      37.5% of our common stock on a fully diluted basis after the offering.
      In December 1999, we entered into an agreement with Banyan Worldwide
      and CBS terminating this agreement.

  .   Stockholders' Voting Agreement. Under this agreement CBS has agreed to
      vote all of its shares of our common stock to elect to our board of
      directors a number of persons designated by Banyan Worldwide as would
      represent a majority of our board of directors. This agreement
      terminates on the first to occur of:

    .   July 2, 2001;

    .   the date on which CBS has required Banyan Worldwide to transfer its
        shares of our common stock to a trustee pursuant to the mandatory
        transfer provisions contained in the advertising and promotion
        agreement; and

    .   the first business day after any person beneficially owns or
        controls more of our voting power than Banyan Worldwide does.

    CBS has agreed that any transfer by it of shares of our common stock
    will require the person receiving the shares to be bound by this
    agreement, except that CBS may transfer shares free of the obligations
    imposed by this agreement if, after giving effect to such transfer, CBS
    would continue to own shares subject to this agreement that represent
    at least 25% of our outstanding common stock. Banyan Worldwide has
    agreed, during the term of this agreement, to retain shares of our
    common stock that represent at least 25% of our outstanding common
    stock.

  .   Registration Rights Agreement. Under this agreement, we granted demand
      and incidental registration rights to CBS. The demand registration
      rights, which allow CBS to require us to file a registration statement
      on their behalf, may be exercised beginning after the first anniversary
      of the closing of this offering. The incidental registration rights,
      which allow CBS to include shares in registration statements we file on
      our own initiative or at the request of other stockholders, are
      effective following the closing of this offering.

 Financial Reporting Agreement

    On January 28, 2000, we entered into a financial reporting agreement with
Banyan Worldwide and CBS pursuant to which we agreed to provide Banyan
Worldwide and CBS with financial information to enable them to comply with
financial reporting requirements relating to their investments in Switchboard.
We also agreed to provide Banyan Worldwide and CBS projections of our financial
information, if requested in order to estimate consolidated financial
information or for tax planning or other similar planning purposes.

Other Transactions and Relationships

 Issuances of Securities

    In November 1996, we issued to each of America Online, Inc. and Digital
City Inc. 375,000 shares of our series A preferred stock at a purchase price of
$4.00 per share. In addition, we issued to each of America Online and Digital
City a warrant to purchase shares of our series B preferred stock equal to
3.75% of our capital stock on the date of exercise, on a fully diluted basis.
The per share exercise price of the warrants is equal to $60.0 million divided
by the number of fully diluted shares of our capital stock on the date of
exercise, and is subject to appropriate adjustment upon the occurrence of any
stock split, stock dividend, reorganization, recapitalization,
reclassification, merger or other similar event. Digital City's warrant to
purchase shares of our series B preferred stock expired prior to the exercise
of any shares under the warrant. We believe that America Online's warrant to
purchase shares of our series B preferred stock has also expired pursuant to
its terms prior to the exercise of the warrant to purchase any shares. See
"Risk Factors--Risks Relating to this Offering--We

                                       63
<PAGE>


may become subject to an equity ownership claim from America Online which, if
successful, would result in substantial additional dilution to investors in
this offering."

 Business Agreements

    In November 1996, in connection with our securities issuances to America
Online and Digital City described above, we entered into an agreement with
America Online and Digital City under which America Online agreed to integrate
Switchboard into its interactive services, and we granted America Online and
Digital City exclusive sales licenses for specified types of advertisements on
our Web site.

    The November 1996 agreement was replaced by two agreements entered into
between us and America Online in December 1997:

  .  an interactive yellow pages marketing agreement under which America
     Online agreed to promote and distribute our yellow pages directory
     services; and

  .  an interactive white pages marketing agreement under which America
     Online agreed to promote and distribute our white pages directory
     services.

    The yellow pages agreement terminated in December 1998, and the white pages
agreement terminated in November 1998. Since November 1996, we have received an
aggregate of approximately $780,000 in license and advertising fees from
America Online and paid America Online an aggregate of approximately $3.0
million in revenue share, carriage fees and sales commissions.

    Since January 1, 1998, we and Digital City have conducted local advertising
sales and distribution activities. Under both the November 1996 agreement
described above, and those local advertising activities, we have received an
aggregate of approximately $413,000 in license and advertising fees from
Digital City, and paid to Digital City an aggregate of approximately $72,000.

    In December 1998, we agreed to resolve a number of outstanding intercompany
balances between us and America Online and Digital City under our prior
agreements, resulting in a net payment by us in March 1999 to America Online of
$423,000. In addition, we agreed to provide America Online with 100 million
impressions on our Web site over a two year term, and America Online granted us
the right to receive up to $200,000 in advertising on America Online properties
over a two year term. If we do not receive the full $200,000 in advertising
during that term, America Online agreed to pay us the difference between
$200,000 and the value of the advertising we actually received. In connection
with these transactions, we amended a number of the rights of America Online
and Digital City as preferred stockholders and pursuant to their investment
agreements with Switchboard, Banyan Worldwide and Continuum Software, Inc. We
also granted to America Online and its affiliates a royalty-free nonexclusive
license to any service or product of America Online which is covered by any
claim of specified patents owned by Switchboard.

 Investor Rights Agreements

    In connection with our issuances of securities to America Online, Digital
City and Banyan Worldwide we granted to America Online, Digital City and Banyan
Worldwide demand and incidental registration rights and a right of first
refusal on future issuances of securities by Switchboard. This right of first
refusal was later terminated in March 1999. Banyan Worldwide, America Online
and Digital City also agreed to grant rights of first refusal and co-sale
rights on transfers of their shares. These agreements have been amended from
time to time, including to add parties. These agreements, as amended to date,
will provide for registration rights after the offering. See "Description of
Capital Stock--Registration Rights."

                             PRINCIPAL STOCKHOLDERS

    The following table sets forth information regarding the beneficial
ownership of our common stock as of December 31, 1999, and as adjusted to
reflect the sale of the shares of common stock in this offering, by:

  .   each person or entity we know to own beneficially more than 5% of our
      common stock;

  .   each of our directors;

  .   each of the Named Executive Officers; and

  .   all directors and executive officers as a group.

    Except as indicated below, none of these persons or entities has a
relationship with us or, to our knowledge, any of the underwriters or their
respective affiliates. Unless otherwise indicated, each person or entity named
in the table has sole voting power and investment power, or shares voting
and/or investment power with his or her spouse, with respect to all shares of
capital stock listed as owned by that person or entity. The address of each of
our employees, officers and directors is c/o Switchboard Incorporated, 115
Flanders Road, Westboro, Massachusetts 01581.

    The number of shares beneficially owned by each stockholder is determined
under rules promulgated by the Securities and Exchange Commission and assumes
the underwriters do not exercise their over-allotment option. The information
is not necessarily indicative of beneficial ownership for any other purpose.
Under these rules, beneficial ownership includes any shares as to which the
individual has sole or shared voting power or investment power and any shares
as to which the individual has the right to acquire beneficial ownership within
60 days after December 31, 1999 through the exercise of any stock option,
warrant or other right. The inclusion in the following table of those shares,
however, does not constitute an admission that the named stockholder is a
direct or indirect beneficial owner of those shares.

                          DESCRIPTION OF CAPITAL STOCK

    We are authorized to issue 85,000,000 shares of common stock, $.01 par
value per share, and 5,000,000 shares of preferred stock, $0.01 par value per
share. As of December 31, 1999, we had outstanding 18,216,355 shares of common
stock held by 21 stockholders of record, options to purchase an aggregate of
2,951,600 shares of our common stock, warrants to purchase 1,751,937 shares of
our common stock and one share of series E special voting preferred stock.

    The following summary of provisions of our common stock, preferred stock,
certificate of incorporation and by-laws is not intended to be complete. It is
qualified by reference to the provisions of applicable law and to our
certificate of incorporation and by-laws included as exhibits to the
registration statement of which this prospectus is a part. See "Where Can You
Find More Information."

Common Stock

    Under our certificate of incorporation, 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, other than
those directors who may be elected by the holder of our series E special voting
preferred stock. 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.

Common Stock Warrants

    On December 31, 1997, we issued to Continuum Software Inc. a warrant to
purchase 300,000 shares of our common stock. The warrant is exercisable, in
whole or in part, until the earlier of December 31, 2000 or the termination of
a technology development and marketing agreement between Switchboard and
Continuum. The exercise price is $2.00 per share. This exercise price is
subject to appropriate adjustment upon the occurrence of any stock split, stock
dividend, reorganization, recapitalization, reclassification, merger or other
similar event.

    On March 31, 1999, we issued warrants to purchase an aggregate of 385,000
shares of our common stock. Warrants were issued in connection with a co-
branded Web site and linking agreement among Switchboard and the warrant
holders. The warrants are exercisable, in whole or in part, until the later of
March 31, 2002 or until the date one year subsequent to the effective date of
the termination of the co-branded Web site and linking agreement. The exercise
price is $8.00 per share. This exercise price is subject to appropriate
adjustment upon the occurrence of any stock split, stock dividend,
reorganization, recapitalization, reclassification, merger or other similar
event.

    We have issued to CBS warrants to purchase 1,066,937 shares of our common
stock. A description of these warrants appears above under the heading "Certain
Transactions--CBS Corporation--Issuances of Securities."

Preferred Stock

  Series E Special Voting Preferred Stock

    Under our certificate of incorporation, our board of directors is
authorized to issue one share of our series E special voting preferred stock.
On June 30, 1999 that share was issued to CBS.

                                       67
<PAGE>

    Other than the special voting rights described in the next paragraph, the
series E share has the rights, preferences, powers, privileges and restrictions
of one share of our common stock. The series E preferred stock is junior to any
other series of preferred stock we may issue with respect to redemption rights
and the right to receive dividends or amounts distributable upon our
liquidation, dissolution or winding up.

    The series E share entitles CBS to elect that number of directors to our
board of directors, rounded down, which equals CBS's fully diluted percentage
ownership of us, up to a maximum of the number of directors which would
constitute a minority of the authorized number of members of the board. If
CBS's ownership percentage is zero, it may still elect one director, so long as
the license agreement which we entered into with CBS on June 30, 1999 remains
in effect.

    CBS's right to elect directors will terminate upon the first to occur of:

  .   the date on which CBS no longer owns any of our securities and the
      license agreement is no longer in effect;

  .   the date on which a competitor of Switchboard owns more than 30% of the
      common stock or securities representing more than 30% of the voting
      power of CBS; and

  .   the date on which the series E share is owned by a person other than
      CBS or an entity controlling, controlled by or under common control
      with CBS.

Upon the termination of CBS's special voting right, the series E share will
automatically convert into one share of common stock. Upon written request at
any time prior to the termination of this voting right, CBS may convert its
series E share to one share of common stock.

  Blank Check Preferred Stock

    Under our certificate of incorporation, our board of directors is
authorized to issue shares of preferred stock in one or more series without
stockholder approval. Our board of directors has the discretion to determine
the rights, preferences, privileges and restrictions, including voting rights,
dividend rights, conversion rights, redemption privileges and liquidation
preferences, of each series of preferred stock.

    The purpose of authorizing our board of directors to issue preferred stock
and determine its rights and preferences is to eliminate delays associated with
a stockholder vote on specific issuances. The issuance of preferred stock,
while providing desirable flexibility in connection with possible acquisitions
and other corporate purposes, could have the effect of making it more difficult
for a third party to acquire, or could discourage a third party from acquiring,
a majority of our outstanding voting stock. Besides our one outstanding share
of series E special voting preferred, we have no present plans to issue any
shares of preferred stock.

Delaware Law and Charter and By-Law Provisions

    We are subject to the provisions of Section 203 of the General Corporation
Law of Delaware. 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 person became an interested stockholder,
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 exceptions, an
"interested stockholder" is a person who, together with affiliates and
associates, owns, or within the prior three years did own, 15% or more of the
corporation's voting stock.

    Our certificate of incorporation divides our board of directors, other than
directors elected by the holder of the series E share, into three classes
serving staggered three-year terms. In addition, our certificate of
incorporation provides that, after July 2, 2001, or, if earlier, the expiration
or termination of the stockholders' voting agreement among CBS, Banyan
Worldwide and Switchboard, directors may be removed only for cause by the
affirmative vote of at least 75% of our shares of capital stock entitled to
vote. Except for series E

                                       68
<PAGE>


directors, any vacancy on our board of directors may only be filled by vote of
a majority of our directors then in office, or by a sole remaining director.
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 us.

    Our certificate of incorporation provides that any action required or
permitted to be taken by our stockholders at an annual meeting or special
meeting of stockholders may only be taken if it is properly brought before the
meeting and may not be taken by written action in lieu of a meeting. Our
certificate of incorporation further provides that special meetings of the
stockholders may only be called by our chairman of the board, chief executive
officer or board of directors. Under our by-laws, in order for any matter to be
considered "properly brought" before a meeting, a stockholder must comply with
advance notice requirements. These provisions could have the effect of
delaying, until the next stockholders' meeting, stockholder actions which are
favored by the holders of a majority of our outstanding voting securities.
These provisions may also discourage a third party from making a tender offer
for our common stock, because even if it acquired a majority of our outstanding
voting securities, the third party would be able to take action as a
stockholder (such as electing new directors or approving a merger) only at a
duly called stockholders' meeting, and not by written consent.

    The General Corporation Law of Delaware 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 by-laws,
unless a corporation's certificate of incorporation or by-laws, as the case may
be, requires a greater percentage. Our certificate of incorporation and by-laws
require the affirmative vote of the holders of at least 75% of the shares of
our capital stock issued and outstanding and entitled to vote to amend or
repeal any of the provisions described in the prior two paragraphs.

    Our certificate of incorporation contains provisions permitted under the
General Corporation Law of Delaware relating to the liability of directors. The
provisions eliminate a director's liability for monetary damages for a breach
of fiduciary duty as a director, except in some circumstances involving
wrongful acts, such as the breach of a director's duty of loyalty or acts or
omissions that involve intentional misconduct or a knowing violation of law.
Further, our certificate of incorporation contains provisions to indemnify our
directors and officers to the fullest extent permitted by the General
Corporation Law of Delaware. We believe that these provisions will assist us in
attracting and retaining qualified individuals to serve as directors.

<PAGE>


  .   Upon the completion of this offering, we intend to enter into an
      agreement with Banyan Worldwide under which Banyan Worldwide may, with

 Incidental Registration Rights

    If we propose to register any of our securities under the Securities Act,
either for our own account or for the account of other security holders
exercising registration rights, the remaining holders of 19,387,918
registrable shares of common stock and rights to acquire common stock, are
entitled to notice of and to include shares of common stock in the
registration. We are required to use our best efforts to effect that
registration. The holders of these incidental rights are as follows:

  .   one other stockholder holds the right to purchase 300,000 registrable
      shares pursuant to a warrant.

    All of the demand and incidental registration rights are subject to
various conditions and limitations, among them the right of the underwriters
of an offering to limit the number of shares included in a registration and
our right not to effect a requested registration within six months after the
effective date of any other registration statement.

Transfer Agent and Registrar

    The transfer agent and registrar for our common stock is Equiserve.

                        SHARES ELIGIBLE FOR FUTURE SALE

    Before this offering, there has been no public market for our securities.
After we complete this offering, based upon the number of shares outstanding
at December 31, 1999, there will be 23,716,355 shares of our common stock
outstanding (assuming no exercise of the underwriters' over-allotment option
and no exercise of outstanding options or warrants to purchase common stock).
Of these outstanding shares, the 5,500,000 shares sold in this offering will
be freely tradeable without restriction or further registration under the
Securities Act of 1933, except that any shares purchased by our "affiliates",
as that term is defined in Rule 144 under the Securities Act, may generally
only be sold in compliance with the limitations of Rule 144 described below.

Sales of Restricted Shares

    The remaining 18,216,355 shares of common stock outstanding after this
offering are deemed "restricted securities" under Rule 144.



    All of these shares are subject to lock-up arrangements which expire 180
days after the date of this prospectus. Upon expiration of the 180-day lock-up
period, all of these shares will be eligible for sale in the public market
subject to the provisions of Rule 144 or Rule 701 under the Securities Act.

    Holders of our securities, including all of our directors and executive
officers, who in the aggregate hold:

  . 18,216,355 shares of our common stock of record;

  .   options to purchase 2,951,600 shares of our common stock;

  .   warrants to purchase 1,751,937 shares of our common stock; and

  .   one share of our series E preferred stock which is convertible into one
      share of our common stock

on the date of this prospectus, have agreed that, for a period of 180 days
after the date of this prospectus, they will not sell, contract to sell or
otherwise dispose of any shares of our common stock, or any shares convertible
into or exchangeable for shares of our common stock, owned directly by them or
with respect to which they have the power of disposition, without the prior
written consent of FleetBoston Robertson Stephens Inc., acting on behalf of
the representatives of the underwriters.

    In general, under Rule 144 a stockholder, including one of our affiliates,
who has beneficially owned his or her restricted securities for at least one
year is entitled to sell, within any three-month period commencing 90 days
after the date of this prospectus, a number of shares that does not exceed the
greater of 1% of the then outstanding shares of our common stock
(approximately 237,164 shares immediately after this offering) or the average
weekly trading volume in our common stock during the four calendar weeks
preceding the date on which notice of the sale was filed under Rule 144,
provided requirements concerning availability of public information, manner of
sale and notice of sale are satisfied. In addition, a stockholder that is not
one of our affiliates at any time during the three months preceding a sale and
who has beneficially owned the shares proposed to be sold for at least two
years is entitled to sell the shares immediately under Rule 144(k) without
compliance with the above described requirements under Rule 144.

    Securities issued in reliance on Rule 701 (such as shares of our common
stock acquired pursuant to the exercise of options granted under our stock
plans) are also restricted securities and, beginning 90 days after the date of
this prospectus, may be sold by stockholders other than our affiliates subject
only to the manner of sale provisions of Rule 144 and by affiliates under Rule
144 without compliance with its one-year holding period requirement.

Stock Options

    We intend to file registration statements on Form S-8 under the Securities
Act to register an aggregate of 5,175,000 shares of common stock issuable
under the 1996 plan, the 1999 plan and the employee stock purchase plan.
Shares issued upon the exercise of stock options after the effective date of
the Form S-8 registration statements will be eligible for resale in the public
market without restriction, subject to Rule 144 limitations applicable to
affiliates and the lock-up agreements noted above, if applicable.

Effect of Sales of Shares

    Prior to this offering, there has been no public market for our common
stock, and no prediction can be made as to the effect, if any, that market
sales of shares of common stock or the availability of shares for sale will
have on the market price of our common stock prevailing from time to time.
Nevertheless, sales of significant numbers of shares of our common stock in the
public market could adversely affect the market price of the common stock and
could impair our future ability to raise capital through an offering of our
equity securities.

on the cover page of this prospectus and to certain dealers at that price less
a concession of not in excess of $  per share, of which $  may be reallowed to
other dealers. After this offering, the public offering price, concession and
reallowance to dealers may be reduced by the representatives. No reduction in
this price will change the amount of proceeds to be received by us as indicated
on the cover page of this prospectus. The common stock is offered by the
underwriters as stated in this prospectus, subject to receipt and acceptance by
them of the common stock and subject to their right to reject any order in
whole or in part.

    Prior to this offering, there has been no public market for the common
stock. Consequently, the public offering price for the common stock offered by
this prospectus will be determined through negotiations among the
representatives and us. Among the factors considered in those negotiations will
be prevailing market conditions, our financial information, market valuations
of other companies that we and the representatives believe to be comparable to
us, estimates of our business potential, the present state of our development
and other factors deemed relevant.

    The underwriters have advised us that they do not expect sales to
discretionary accounts to exceed five percent of the total number of shares
offered.

 Over-Allotment Option

    We have granted to the underwriters an option, exercisable during the 30-
day period after the date of this prospectus, to purchase up to 825,000
additional shares of common stock, to cover over-allotments, if any, at the
public offering price less the underwriting discount located on the cover page
of this prospectus. If the underwriters exercise their over-allotment option to
purchase any of the 825,000 additional shares of common stock, the underwriters
have severally agreed, subject to certain conditions, to purchase approximately
the same percentage of these additional shares as the number of shares to be
purchased by each of them bears to the total number of shares of common stock
offered in this offering. If purchased, these additional shares will be sold by
the underwriters on the same terms as those on which the shares offered by this
prospectus are being sold. We will be obligated, pursuant to the over-allotment
option, to sell shares to the underwriters to the extent the over-allotment
option is exercised. The underwriters may exercise the over-allotment option
only to cover over-allotments made in connection with the sale of the shares of
common stock offered in this offering.

</TABLE>

    We estimate expenses payable by us in connection with this offering, other
than the underwriting discounts and commissions referred to above, will be
approximately $2,000,000.

 Indemnity

    The underwriting agreement contains covenants of indemnity among the
underwriters and us against some civil liabilities, including liabilities under
the Securities Act, and liabilities arising from breaches of representations
and warranties contained in the underwriting agreement.

 Lock-Up Agreements

    Each executive officer and director of Switchboard and substantially all
other holders of our securities have agreed during the period of 180 days after
the effective date of this prospectus, subject to specified exceptions, not to
offer to sell, contract to sell, or otherwise sell, dispose of, loan, pledge or
grant any rights with respect to any shares of common stock or any options or
warrants to purchase any shares of common stock, or any securities convertible
into or exchangeable for shares of common stock owned as of the date of this
prospectus or thereafter acquired directly by those holders or with respect to
which they have the power of disposition, without the prior written consent of
FleetBoston Robertson Stephens Inc. However, FleetBoston Robertson Stephens
Inc. may, in its sole discretion and at any time or from time to time, without
notice, release all or any portion of the securities subject to lock-up
agreements. There are no existing agreements between the representatives and
any of our stockholders who have executed a lock-up agreement providing consent
to the sale of shares prior to the expiration of the lock-up period.

    In addition, we have agreed that during the lock-up period we will not,
without the prior written consent of FleetBoston Robertson Stephens Inc.,
subject to limited exceptions, consent to the disposition of any shares held by
stockholders subject to lock-up agreements prior to the expiration of the lock-
up period, or issue, sell, contract to sell, or otherwise dispose of, any
shares of common stock, any options or warrants to purchase any shares of
common stock or any securities convertible into, exercisable for or
exchangeable for shares of common stock other than our sale of shares in this
offering, the issuance of our common stock upon the exercise of outstanding
options or warrants, and the issuance of options under existing stock option
and incentive plans provided that those options do not vest prior to the
expiration of the lock-up period. See "Shares Eligible for Future Sale."

 Listing

    We have applied to have our common stock approved for quotation on the
Nasdaq National Market under the symbol "SWBD."

 Stabilization

    The representatives have advised us that, pursuant to Regulation M under
the Securities Act of 1933, some persons participating in the offering may
engage in transactions, including stabilizing bids, syndicate covering
transactions or the imposition of penalty bids, that may have the effect of
stabilizing or maintaining

                                       74
<PAGE>

the market price of the shares of common stock at a level above that which
might otherwise prevail in the open market. A "stabilizing bid" is a bid for or
the purchase of shares of common stock on behalf of the underwriters for the
purpose of fixing or maintaining the price of the common stock. A "syndicate
covering transaction" is the bid for or purchase of common stock on behalf of
the underwriters to reduce a short position incurred by the underwriters in
connection with the offering. A "penalty bid" is an arrangement permitting the
representatives to reclaim the selling concession otherwise accruing to an
underwriter or syndicate member in connection with the offering if the common
stock originally sold by that underwriter or syndicate member is purchased by
the representatives in a syndicate covering transaction and has therefore not
been effectively placed by that underwriter or syndicate member. The
representatives have advised us that these transactions may be effected on the
Nasdaq National Market or otherwise and, if commenced, may be discontinued at
any time.

 Directed Share Program

    The underwriters have reserved up to ten percent of the common stock to be
issued by us and offered for sale in this offering, at the initial public
offering price, to directors, officers, employees, business associates and
persons otherwise connected to Switchboard. The number of shares of common
stock available for sale to the general public will be reduced to the extent
these individuals purchase reserved shares. Any reserved shares which are not
purchased will be offered by the underwriters to the general public on the same
basis as the other shares offered in this offering.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Stockholders of Switchboard Incorporated:

    In our opinion, the accompanying balance sheets and the related statements
of operations, stockholders' deficit and cash flows present fairly, in all
material respects, the financial position of Switchboard Incorporated at
December 31, 1998 and 1999 and the results of its operations and its cash flows
for the years ended December 31, 1997, 1998 and 1999, in conformity with
accounting principles generally accepted in the United States. These financial
statements are the responsibility of Switchboard's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States, which 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, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

                         SWITCHBOARD INCORPORATED

                       NOTES TO FINANCIAL STATEMENTS

A. Nature of Business:

    Switchboard is an Internet-based local merchant network interconnecting
consumers, merchants and national advertisers. Switchboard connects consumers
searching for specific products and services with the merchants that provide
them. Switchboard offers its users local information about people and
businesses across the United States. Switchboard's online network gives local
merchants a way to get their businesses represented online and facilitates
commerce by connecting them with consumers. Switchboard provides an online lead
generation engine for these local merchants and for national advertisers that
reaches consumers motivated to buy products and services in specific geographic
locations. Switchboard operates in one business segment.

    From Switchboard's inception (February 19, 1996) until December 31, 1999,
Switchboard has been a unit and later a subsidiary of Banyan Systems
Incorporated ("Banyan Worldwide").

    Switchboard is subject to risks and uncertainties common to growing
technology-based companies, including rapid technological change, growth and
commercial acceptance of the Internet, acceptance and effectiveness of Internet
advertising, dependence on principal products and third-party technology, new
product development, new product introductions and other activities of
competitors, dependence on key personnel, security and privacy issues,
dependence on strategic relationships, and limited operating history.

    Switchboard has also experienced substantial net losses since its inception
and, as of December 31, 1999, had an accumulated deficit of $21.0 million. Such
losses and accumulated deficit resulted from Switchboard's lack of substantial
revenue and significantly increased costs incurred in the development of
Switchboard's products and services and in the preliminary establishment of
Switchboard's infrastructure. Switchboard expects to continue to experience
significant growth in its operating expenses in order to execute its current
business plan, particularly product development and sales and marketing
expenses. As a result, Switchboard's business plan indicates that additional
financing would be required to support its planned expenditures. In the event
that an initial public offering is not completed on a timely basis, Switchboard
believes that the funds currently available, together with the collateralized
convertible note facility from Banyan Worldwide (Note F), would be sufficient
to fund operations through at least the next 12 months.

B. Summary of Significant Accounting Policies:

 Basis of Presentation

    From inception, Switchboard has been a unit of and later a subsidiary of
Banyan Worldwide. The accompanying financial statements, which are derived from
the historical books and records of Banyan Worldwide, include the assets,
liabilities, revenues and expenses of Switchboard at historical cost.

    These financial statements are intended to present management's estimates
of the results of operations and financial condition of Switchboard as if it
had operated as a stand-alone company since inception. Certain of the costs and
expenses are management estimates of the cost of services provided by Banyan
Worldwide and its subsidiaries. As a result, the financial statements presented
may not be indicative of the results that would have been achieved had
Switchboard operated as a nonaffiliated entity.

 Use of Estimates

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

                         SWITCHBOARD INCORPORATED

                NOTES TO FINANCIAL STATEMENTS--(Continued)


 Cash and Cash Equivalents

    Switchboard considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. Cash equivalents are
carried at amortized cost, which approximates market, and consist primarily of
interest bearing deposits with major financial institutions.

 Property and Equipment

    Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the following estimated asset lives:

<TABLE>
       <S>                                                             <C>
       Computers, peripherals and servers.............................   3 years
       Equipment...................................................... 2-5 years
       Software.......................................................   3 years
</TABLE>

    Maintenance and repairs are charged to expense when incurred, while
betterments are capitalized. When property is retired or otherwise disposed of,
the related cost and accumulated depreciation are removed from the respective
amounts and any gain or loss is reflected in operations.

 Product Development

    Costs incurred in the development of Switchboard's Web site are expensed as
incurred, except for certain software development costs. Costs associated with
the development of computer software are expensed prior to the establishment of
technological feasibility and capitalized thereafter. Amortization of
capitalized software costs is computed on an individual project basis and is
calculated using the straight-line method over the estimated economic life of
the software. Currently, Switchboard uses an estimated economic life of 12 to
36 months for capitalized software costs.

    Switchboard evaluates the net realizable value of capitalized software on
an ongoing basis, relying on a number of factors including operating results,
business plans, budgets, economic projections and undiscounted cash flows. In
addition, Switchboard's evaluation considers nonfinancial data such as market
trends, project development cycles and changes in management's market emphasis.

    In 1999, the Company adopted SOP 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use." The adoption of SOP
98-1 did not have a material impact on Switchboard's financial position or
results of operations.

 Advertising Expense

    Advertising costs are expensed as incurred and totaled $202,195,
$3,296,431, and $6,611,694 in the years ended December 31, 1997, 1998 and 1999,
respectively. In 1999, the cost included $4,069,246 of non-cash advertising
related to the CBS relationship (Note I).

 Revenue Recognition

    Switchboard generates its revenue from Web site advertising, syndication
and licensing fees for its directory technologies, and its merchant aggregation
program.

    Switchboard's advertising revenue is derived principally from short-term
advertising contracts and sponsorship agreements in which Switchboard receives
a fixed fee or earns a fee based on a per thousand impressions or per click
basis. Revenue from advertising is recognized as the services are delivered
provided

                                      F-8

                         SWITCHBOARD INCORPORATED

                NOTES TO FINANCIAL STATEMENTS--(Continued)

that no significant Switchboard obligations remain and collection of the
resulting receivable is probable. The duration of Switchboard's advertising
commitments from customers typically range from two weeks to one year. Revenue
from revenue-sharing agreements is recognized in the period following that in
which the services are provided and when the revenue amount can be determined.

    Switchboard's syndication and licensing revenue consists of fees for
engineering work performed to integrate Switchboard's directory sites with a
customer's Web site, as well as for supplying access to Switchboard's directory
sites. The syndication and licensing fees are usually paid at the beginning of
the contract period and are typically nonrefundable. The fees are recognized
ratably over the term of the contract.

    Switchboard's merchant aggregation program revenue consists of subscription
fees for merchant Web sites, which are linked to Switchboard's yellow pages
directory site, as well as customer acquisition fees paid by program partners
for the initiation and set-up of new local merchant Web sites. Subscription
fees are recognized over the period that the local merchant Web site is in
place, usually on a monthly basis. Customer acquisition fees are recognized
when the local merchant Web site construction is complete.

    Deferred revenue is principally comprised of billings in excess of
recognized revenue relating to advertising agreements and licensing fees
received pursuant to advertising or services agreements in advance of revenue
recognition.

 Risks and Uncertainties

    Switchboard invests its cash and cash equivalents primarily in deposits and
money market funds with financial institutions. Switchboard has not experienced
any losses to date on its invested cash.

    A potential exposure to Switchboard is a concentration of credit risk in
trade accounts receivable. Switchboard maintains reserves for credit losses
and, to date, such losses have been within management's expectations. As of
December 31, 1998, one customer accounted for 16.8% of accounts receivable
while three customers accounted for 16.7%, 12.0%, and 10.7% of accounts
receivable as of December 31, 1999. In addition, one customer accounted for
13.7% of revenue for the year ended December 31, 1997, while three customers
accounted for 11.9%, 10.5% and 10.2% of revenue for the year ended December 31,
1998. One customer accounted for 22.7% of revenue for the year ended December
31, 1999.

 Income Taxes

    Switchboard accounts for income taxes under the asset and liability method.
Under this method, deferred tax assets and liabilities are recognized for the
estimated future tax consequences attributable to differences between the
financial statement carrying amounts of existing assets and liabilities and
their respective tax bases. Deferred tax assets and liabilities are measured
using enacted rates in effect for the year in which those temporary differences
are expected to be recovered or settled. A deferred tax asset is established
for the expected future benefit of net operating loss and credit carryforwards.
A valuation reserve against net deferred tax assets is required if, based upon
available evidence, it is more likely than not that some or all of the deferred
tax assets will not be realized.

 Fair Value of Financial Instruments

    The carrying amounts of Switchboard's financial instruments, which include
cash equivalents, accounts receivable, accounts payable, accrued expenses and a
note payable approximate their fair values.

                NOTES TO FINANCIAL STATEMENTS--(Continued)


 Accounting for Stock-Based Compensation

    Switchboard accounts for stock-based awards to employees using the
intrinsic value method as prescribed by Accounting Principles Board ("APB")
No. 25, "Accounting for Stock Issued to Employees," and related
interpretations. Accordingly, no compensation expense is recorded for options
issued to employees in fixed amounts and with fixed exercise prices at least
equal to the fair market value of Switchboard's common stock at the date of
grant. Switchboard has adopted the provisions of Statement of Accounting
Standards ("SFAS") No. 123, "Accounting for Stock-Based Compensation," through
disclosure only (Note N). All stock-based awards to nonemployees are accounted
for at their fair value in accordance with SFAS No. 123.

 Pro Forma Balance Sheet

    Upon the closing of Switchboard's anticipated initial public offering, all
of the outstanding shares of Series A, B, C and D Convertible Preferred Stock
will automatically convert into 3,552,421 shares of common stock. These
conversions have been reflected in the pro forma balance sheet as of December
31, 1999. The one outstanding share of Series E Special Voting Preferred Stock
will not convert to common stock upon the closing of the anticipated initial
public offering (Note I and M).

    In October 1999, the Board of Directors approved the amendment and
restatement of Switchboard's Certificate of Incorporation to authorize
capitalization of Switchboard of 85,000,000 shares of common stock, $0.01 par
value per share, and 5,000,000 shares of preferred stock, $0.01 par value per
share. The amendment will be effective upon the closing of an initial public
offering and has been reflected in the pro forma balance sheet as of December
31, 1999.

 Net Loss per Share and Pro Forma Net Loss per Share

    Basic net loss per share is computed using the weighted average number of
shares of common stock outstanding. Net loss used in the calculation is
increased by the accrued dividends for the preferred stock outstanding in each
period. Diluted net loss per share does not differ from basic net loss per
share since potential common shares from conversion of preferred stock, stock
options and warrants are antidilutive for all periods presented and are
therefore excluded from the calculation. During the years ended December 31,
1997, 1998 and 1999, options to purchase 1,007,000, 1,162,875 and 2,951,600
shares of common stock, respectively, preferred stock convertible into
750,000, 750,000 and 3,552,422 shares of common stock, respectively, and
warrants for 300,000, 300,000 and 1,751,937 shares of common stock,
respectively, were not included in the computation of diluted net loss per
share since their inclusion would be antidilutive. Pro forma basic and diluted
net loss per share have been calculated assuming the conversion of all
outstanding shares of preferred stock into common stock, as if the shares had
converted immediately upon their issuance.

 Derivative Instruments and Hedging

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." The new standard establishes accounting
and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts, and for hedging
activities. SFAS No. 133, as amended by SFAS 137, is effective for all fiscal
quarters of fiscal years beginning after June 15, 2000. Switchboard does not
expect SFAS No. 133 to have a material effect on its financial position or
results of operations.

 Other Comprehensive Income

    Comprehensive income is equal to net income for the years ended December
31, 1997, 1998 and 1999.

</TABLE>

    During 1997, Switchboard capitalized $10,764 of software costs. There were
no costs eligible for capitalization in 1998 or 1999. Amortization expense for
other assets was $40,796, $118,228, and $412,696 for the years ended December
31, 1997, 1998 and 1999, respectively.

    On May 18, 1998, Switchboard acquired the Maps On Us Internet mapping
technology from Lucent Technologies Incorporated. The technology was acquired
to integrate it into Switchboard's directory Web site. Switchboard paid Lucent
$500,000 in cash and executed a note payable of $1,100,000 to be paid over a
two-year period. The note bears interest at a rate of 6.75%. At December 31,
1999, $600,000 of principal is outstanding under the note.

    A significant portion of the technology acquired was deemed incomplete as
it did not meet the criteria for capitalization. The technology was incomplete
because the technology required a substantial development effort by Switchboard
in order to successfully integrate the Maps On Us technology into Switchboard's
Web site. In addition, the technology had no alternative future use to
Switchboard inasmuch as Switchboard had acquired the technology to improve and
integrate it into the Switchboard Web site and not to market it as a standalone
product. Further, Switchboard had no other product, line of business or product
development project that could use the technology. Therefore, Switchboard
recorded a charge to product development of $1,400,000 for the purchase of
incomplete technology in 1998.

    In August 1999, in connection with a Development, Access and License
agreement with a third party, Switchboard was issued a warrant for 150,000
shares of common stock, with an exercise price of $9.19 per share. Switchboard
attributed no value to the warrant. The underlying common stock of the third
party is publicly traded and can be registered at the demand of Switchboard any
time after June 16, 2000. The warrant expires on June 30, 2002.

F. Convertible Promissory Notes:

    On August 29, 1997, Switchboard entered into a collateralized convertible
note facility with Banyan Worldwide. The facility was initially for $3,000,000,
and was increased on February 20, 1998 to $7,000,000 and on May 3, 1999 to
$10,000,000. Outstanding amounts under the facility bore interest at a rate
equal to the applicable federal rate under Section 1274 of the Internal Revenue
Code of 1986, as amended, for short-term loans with annual compounding interest
for the month in which such loan was made and were due and payable on June 30,
2000. At December 31, 1997, 1998 and 1999 the interest rate in effect was
5.68%, 4.33%, and 5.74%, respectively. The outstanding amount of principal and
interest was convertible at the option of Banyan Worldwide into shares of
Series C Convertible Preferred Stock at a rate of $4.00 per share, subject to
adjustment, at any time. The entire outstanding amount of principal and
interest was converted on June 30, 1999 (Note M). Switchboard may not borrow
any additional amounts under this facility.

    On May 3, 1999, Switchboard entered into a second collateralized
convertible note facility with Banyan Worldwide. This facility was subsequently
amended and restated in its entirety on January 26, 2000. The facility was
originally for $5,000,000. Outstanding amounts bear interest at a rate equal to
the applicable federal rate under Section 1274 of the Internal Revenue Code of
1986, as amended, for short-term loans with annual compounding interest for the
month in which such loan was made and are due and payable on January 1, 2001.
At December 31, 1999, the interest rate in effect was 5.74%. The outstanding
amount of principal and interest is convertible at the option of Banyan
Worldwide into shares of Series D Convertible Preferred Stock at $11.00 per
share, subject to adjustment, at any time. The entire amount of principal and
interest shall automatically be converted immediately prior to the consummation
of an underwritten public offering in which Switchboard, prior to giving effect
to the proceeds of the offering, is valued at at least $135,000,000 and
resulting in at least $15,000,000 in net proceeds. Upon consummation of such a
qualified offering, this facility shall be deemed cancelled in full and no
further advances shall be made thereunder.

    On June 30, 1999, Switchboard issued 87,345 shares of Series D Convertible
Preferred Stock to Banyan Worldwide upon the conversion by Banyan Worldwide of
principal and interest of $655,089 under this facility. The dollar amount
converted represented an estimate of all of the principal and interest
outstanding as of June 30, 1999. As of July 1, 1999, Switchboard issued 59,160
additional shares of Series D Convertible Preferred Stock to Banyan Worldwide
upon the conversion by Banyan Worldwide of principal and interest of $443,699
under this facility. The additional dollar amount converted represented the
actual amount of all of the principal and interest outstanding as of June 30,
1999, after giving effect to the estimate Switchboard made on

June 30, 1999. This conversion was made by Banyan Worldwide to put Banyan
Worldwide and CBS in the equity ownership position they would have been in had
the actual amount of outstanding principal and interest at June 30, 1999 been
known on June 30, 1999. The facility remains in place and the maximum remaining
amount available under the facility is $3,904,328.

    Borrowings from Banyan Worldwide in excess of the amounts available under
the Convertible Promissory Notes are classified as due to parent on the balance
sheet. This amount bears interest at the same rate as the borrowings under the
Convertible Promissory Notes.

G. Related Parties:

    Switchboard and Banyan Worldwide have entered into a corporate services
agreement dated November 1, 1996 under which Banyan Worldwide's corporate staff
provides certain administrative services, including financial and accounting,
human resources and payroll advice, treasury, tax and insurance services and
routine data processing, technical support and equipment maintenance services
for which Switchboard pays Banyan Worldwide a monthly fee based on
Switchboard's headcount and the level of services provided by Banyan Worldwide.
The fee is reviewed and adjusted periodically by mutual agreement of the
parties. For these services, Switchboard was charged $335,229, $199,852 and
$295,788 in 1997, 1998 and 1999, respectively. Management believes that the
service fees charged by Banyan Worldwide are reasonable and that such fees are
representative of the expenses Switchboard would have incurred on a stand-alone
basis. The corporate services agreement extends for a period of three years and
thereafter renews annually unless either party terminates the agreement with 90
days' notice to the other.

    For additional items such as development of data processing systems and
programs, legal support, support in financing and acquisition transactions,
general executive and management services, and support for contract bidding,
Switchboard is charged based on Banyan Worldwide's labor costs for the employee
performing the services. Further, Switchboard reimburses Banyan Worldwide for
its pro rata share of telephone, photocopying, postage and employee benefit
plan expenses.

    Switchboard leases the space it occupies under an agreement with Banyan
Worldwide. Switchboard pays Banyan Worldwide rent in an amount that is
approximately equal to its pro rata share of Banyan Worldwide's occupancy
costs. Switchboard's share of Banyan Worldwide's occupancy costs was $184,464,
$172,501, and $195,156 in 1997, 1998 and 1999, respectively.

    Certain directors of Switchboard hold positions as officers or directors of
Banyan Worldwide. The Chairman of the Board of Directors of Switchboard is also
Chairman of the Board of Directors, President and Chief Executive Officer of
Banyan Worldwide. One director of Switchboard is Vice President and Chief
Financial Officer of Banyan Worldwide.

H. Strategic Alliance:

    As of November 6, 1996, Switchboard entered into an agreement with America
Online, Inc. ("AOL") and Digital City Inc. ("DCI") whereby Switchboard provided
yellow pages and white pages services on the AOL service. Under the terms of
the agreement, Switchboard derived advertising revenue based on the sale of
advertising by Switchboard, AOL and DCI. The agreement was to extend until
December 31, 1997. As of December 31, 1997, the November 1996 agreement was
replaced by two agreements, one for the promotion of Switchboard's yellow pages
service on certain AOL properties and the other for similar promotion of
Switchboard's white pages service. These agreements were to extend until
December 31, 1998.

                            SWITCHBOARD INCORPORATED

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

    In 1998, AOL terminated each agreement, and removed Switchboard from its
Web site in November and December 1998. On December 31, 1998, Switchboard, AOL
and DCI agreed to a settlement to resolve the amounts due between the parties.
Under the terms of the settlement, Switchboard was required to pay AOL $839,194
for certain carriage payments and other amounts due, and DCI was required to
pay Switchboard $116,064 for publication fees. Additionally, AOL was required
to pay Switchboard $500,000, of which $200,000 is to be paid in the form of
advertising inventory on certain AOL properties or, to the extent that such
advertising inventory has not been provided by the end of a two-year period, in
cash. The amounts due from AOL were recorded as revenue in 1998. As of December
31, 1999, the $200,000 has not yet been paid.

I. CBS Advertising, Promotion and License Agreement:

    In 1999, Switchboard and CBS Corporation ("CBS") consummated a number of
agreements under which CBS acquired a 35% equity stake in Switchboard, through
the issuance of 7,468,560 shares of Switchboard common stock and one share of
Series E Special Voting Preferred Stock (Notes L and M). In exchange,
Switchboard received $5,000,000 in cash and will receive advertising and
promotional value over a term of seven years, across the full range of CBS
media properties, as well as those of its radio and outdoor subsidiary,
Infinity Broadcasting Corporation. As part of the transactions, CBS was also
issued warrants to purchase up to an additional 1,066,937 shares of Switchboard
common stock at a per share exercise price of $1.00, which would increase its
ownership position in Switchboard to 40%. The warrants are not exercisable by
CBS until the earlier of (i) June 30, 2001 or (ii) the closing of an initial
public offering of Switchboard's common stock and are not exercisable after the
earlier of (i) the second anniversary of an initial public offering of
Switchboard's common stock or (ii) June 30, 2004. The number of shares of
common stock and warrants issued to CBS are subject to adjustment in the event
of certain future issuances of securities by Switchboard.

    The Advertising and Promotion Agreement dated as of June 30, 1999 and among
Switchboard, Banyan Worldwide and CBS provides advertising with a future value
of $95 million to Switchboard over a seven-year period, subject to one year
renewals upon the mutual written agreement of Switchboard, Banyan and CBS. The
net present value of the advertising has been recorded as a contribution
receivable for the common stock issued. The contribution receivable will be
reduced as Switchboard utilizes advertising based on the proportion of
advertising provided to the total amount to be provided over the seven-year
term. CBS is required to provide advertising and promotion services on an
annual basis as follows:

    The value of advertising provided will be based on the average paid unit
price, excluding barter, for similar services provided to third parties during
the month prior to the delivery of the advertising services. Switchboard may
elect to defer to a subsequent contract year up to 35% of the advertising and
promotional value, provided, however, that CBS not be required to provide
advertising and promotional value in excess of $18,900,000 in any given
contract year.

    Switchboard is required to pay CBS a 25% revenue share on the net
advertising revenues derived from the sale of advertising displayed to CBS
users through the co-branded interfaces or vertical guides during the

term of the agreement. Additionally, Switchboard is required to pay a 12% sales
commission for advertising sold by CBS on the Switchboard Web site, or on
advertisements displayed to CBS users through co-branded interfaces or vertical
guides. In the event that the agreement is terminated by Switchboard for cause,
as defined in the agreement, in lieu of performing the advertising and
promotional obligations CBS may elect to pay in cash the difference between $95
million and the amount of promotional value provided to date. CBS may pay the
cash over the original term of the agreement or in a lump sum payment equal to
the net present value of the amount due.

    Banyan Worldwide has agreed to indemnify CBS for breaches by Switchboard of
representations, warranties and covenants in the Advertising and Promotion
Agreement. The indemnification obligations with respect to the covenants will
expire upon the first to occur of: (i) the first business day after June 30,
2001 when Banyan Worldwide owns or controls less than a majority of
Switchboard's voting power; and (ii) the first business day after any person
owns or controls more of Switchboard's voting power than Banyan Worldwide does.
Switchboard has agreed to indemnify Banyan Worldwide for amounts that Banyan
Worldwide may be required to pay to CBS pursuant to Banyan Worldwide's
indemnification obligations to CBS.

    CBS and Switchboard also entered into a License Agreement dated as of June
30, 1999 which provides a ten-year license, subject to extension, to
Switchboard for the utilization of the CBS trademarks in identifying, marketing
and promoting the Switchboard Web site. If Switchboard terminates the agreement
for cause, as defined in the agreement, CBS must pay $3.5 million to
Switchboard for each year remaining in the agreement at the date of
termination.

    Additionally, Banyan Worldwide issued a common stock purchase warrant to
CBS on June 30, 1999, whereby CBS received warrants to purchase 250,000 shares
of Banyan Worldwide's common stock at $11.27 per share. Switchboard has
recorded the fair value of the Banyan Worldwide warrants based on the Black-
Scholes model as a common stock issuance cost of $375,000.

J. Commitments and Contingencies:

    Switchboard's facilities are provided by Banyan Worldwide as part of the
corporate services agreement, which is renegotiated on a periodic basis (Note
G).

    Under a licensing agreement, Switchboard is obligated to pay minimum
royalties of $400,000, $450,000, and $500,000 in the years 2000, 2001, and
2002, respectively.

K. Income Taxes:

    The provision for income taxes consists of the following:

    Of the $6,602,000 valuation allowance at December 31, 1999, $226,000
relating to deductions for nonqualified stock options will be credited to paid-
in capital, if realized.

    As of December 31, 1999, Switchboard has federal and state net operating
loss carryforwards of approximately $14,200,000, which begin to expire in 2011
and 2001, respectively. Switchboard's available net operating loss
carryforwards have been reduced by approximately $5,137,000 due to the
utilization of the net operating losses in Banyan Worldwide's consolidated tax
return.

    Ownership changes resulting from Switchboard's issuance of capital stock
may limit the amount of net operating loss carryforwards that can be utilized
annually to offset future taxable income. The amount of the annual limitation
is determined based upon the Switchboard's value immediately prior to the
ownership change. Subsequent significant changes in ownership could further
affect the limitation in the future.

L. Common Stock and Common Stock Warrants:

    In 1996, Banyan Worldwide assigned all of its right, title and interest in
the Switchboard software to Switchboard, transferred net assets including
accounts receivable, property and equipment, capitalized software costs, and
deferred revenue, valued at $546,478 and settled advances of $697,093 from
Banyan Worldwide in exchange for 7,000,000 shares of Switchboard common stock.

    In November 1997, Switchboard entered into a technology development and
marketing agreement with a software provider. Under the terms of the agreement,
Switchboard received certain rights in the technology of the software provider
and certain services from the software provider to further develop the
technology. Upon the initial delivery of the technology, Switchboard issued a
warrant to purchase 300,000 shares of common stock at $2.00 per share. The
warrants were fully vested at the issue date. The fair value of the warrant at
the time of issuance was estimated to be $192,600 using the Black-Scholes
model. The fair value was recorded as product development expense at the date
of issuance, because the technology had not reached technological feasibility.

    The software provider agreement provided for an additional issuance of
equity in Switchboard upon delivery of the next release of the technology in
accordance with jointly developed specifications, either in the form of a
warrant for or shares of common stock. In May 1999, Switchboard issued 140,000
shares of common stock to the software provider upon acceptance of the
technology by Switchboard. Switchboard capitalized $1,050,000, the fair value
of Switchboard common stock on the date of issuance, as the technology had
reached technological feasibility, and is amortizing that value over a two-year
period.

    In March 1999, in connection with a co-branded website and linking
agreement ("Web site Agreement") with a joint venture customer, Switchboard
issued a series of warrants for 385,000 shares of common stock at $8.00 per
share. The Web site Agreement expires on October 31, 2000, except in the event
of the dissolution of the joint venture. In that case, the Web site Agreement
will terminate at the time of the joint venture dissolution, provided that the
customer informs Switchboard of the joint venture dissolution before December
1, 1999. No notification of dissolution was received by Switchboard. If the
customer terminates the agreement for any reason other than cause or the
dissolution of the joint venture, the customer will be required to pay $200,000
to Switchboard.

    At the execution of the Web site Agreement, warrants to purchase up to an
aggregate of 233,750 shares of common stock vested immediately ("Initial
Warrants"). The warrants for the remaining shares ("Additional Warrants")
vested on December 31, 1999. The value of the Initial Warrants was estimated to
be $200,558 on the date of issuance using the Black-Scholes model and is being
amortized as sales and marketing expense over the nineteen-month term of the
Web site Agreement. The value of the Additional Warrants was estimated to be
$129,773 on the date of issuance using the Black-Scholes model. The value of
the Additional Warrants was adjusted to market at each balance sheet date until
December 31, 1999 and is being amortized as sales and marketing expense over
the nineteen-month term of the Web site Agreement. On December 31, 1999, the
total value of the Additional Warrants was $848,815.

    In 1999, Switchboard issued 7,468,560 shares of common stock and a warrant
to purchase up to 1,066,937 shares of common stock to CBS Corporation (Note I).

    Switchboard is authorized to issue 10,000,000 shares of preferred stock,
$0.01 par value, 750,000 of which are designated as Series A Convertible
Preferred Stock ("Series A Preferred Stock"), 1,500,000 of which are designated
as Series B Convertible Preferred Stock ("Series B Preferred Stock"), 4,000,000
of which are designated as Series C Convertible Preferred Stock ("Series C
Preferred Stock"), 1,500,000 of which are designated as Series D Convertible
Preferred Stock ("Series D Preferred Stock") and one of which is designated as
Series E Special Voting Preferred Stock ("Series E Preferred Stock").

    At December 31, 1999, Switchboard had 3,552,422 shares of common stock
reserved for conversion of the preferred stock.

 Series A, B, C and D Preferred Stock

    The Series A, B, C and D Preferred Stock is voting. Dividends may be
declared and paid when determined by the Board of Directors. The Series A, B, C
and D Preferred Stock is convertible at any time by the holders, at the then
applicable conversion rate adjusted from time to time (one to one on the date
of issuance). Upon liquidation, the holders of the Series A, B, C and D
Preferred Stock are entitled to receive, out of funds then generally available,
an amount equal to $4.00 per share in the case of Series A Preferred Stock and
Series C Preferred Stock, $6.00 per share in the case of Series B Preferred
Stock and $7.50 per share in the case of Series D Preferred Stock, plus any
declared and unpaid dividends. Following payment to holders of all other
classes of preferred stock, the Series A, B, C and D Preferred Stock holders
are then entitled to share in the remaining available funds on an "as if
converted" basis.

    Shares of the Series A, B, C and D Preferred Stock automatically convert
into common stock upon the closing of a qualified public offering, which is
defined as an offering in which Switchboard is valued at at least $135,000,000
(determined by multiplying the number of outstanding shares of capital stock of
Switchboard on a fully diluted basis by the initial offering price) and
resulting in at least $15,000,000 of net proceeds (determined by subtracting
underwriters' discounts and commissions from gross proceeds).

    In the case of a liquidation due to a consolidation or merger of
Switchboard with or into another company in which Switchboard is not the
surviving entity, the holders of Series A, B, C and D Preferred Stock can elect
to convert their shares of preferred stock into the shares of stock or other
securities of the surviving entity in lieu of receiving cash payments.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

    At the option of the holders of preferred stock, Switchboard is required to
redeem the Series A, B, C and D Preferred Stock at a price equal to $4.00,
$6.00, $4.00 and $7.50, respectively, plus accrued interest at the prime rate
plus 2% (10.50% on December 31, 1999), plus any declared and unpaid dividends,
in three equal annual payments, plus interest thereon, beginning June 30, 2000.
The accrued interest is recorded as accrued dividends to preferred stockholders
in the statement of operations.

    In November 1996, Switchboard issued 750,000 shares of Series A Preferred
Stock at $4.00 per share to American Online, Inc. ("AOL") and Digital City Inc.
("DCI") for total consideration of $3,000,000. In connection with this
transaction, Switchboard issued warrants to each of AOL and DCI to purchase
shares of Series B Preferred Stock equal to 3.75% of Switchboard's capital
stock on the date of exercise, on a fully diluted basis. The per share exercise
price is equal to $60 million divided by the number of fully diluted shares of
Switchboard's capital stock on the date of exercise, and is subject to
adjustment. The warrant expires at the earlier of (i) the date on which AOL
ceases to promote Switchboard through a link to the Switchboard Web site
through the AOL service or AOL.com or (ii) November 5, 2000. The warrant to DCI
expired unexercised on December 31, 1997. AOL has indicated in the past that
its warrant is still outstanding; however, management believes that the warrant
to AOL expired, pursuant to its terms. If the warrants were deemed outstanding
at December 31, 1999, the exercise price would be $2.56 per share. Assuming
consummation of this offering, the exercise price would be $2.07, based on
fully diluted shares at December 31, 1999, including the assumed issuance of
5,500,000 shares in this offering. For the purposes of these calculations fully
diluted shares includes 18,216,355 shares of common stock on a pro forma basis,
options to purchase 2,951,600 shares of common stock, warrants for 1,751,937
shares of common stock, and 466,785 shares of common stock and warrants to
purchase 66,683 additional shares of common stock that would be issued in
accordance with anti-dilution provisions of the CBS agreement.

    No shares of Series B Preferred Stock have been issued to date.

    In 1999, Switchboard issued 2,655,916 shares of Series C Preferred Stock
and 146,505 shares of Series D Preferred Stock to Banyan Worldwide upon the
conversion of outstanding convertible promissory notes outstanding (Note F).

 Series E Preferred Stock

    On June 30, 1999, Switchboard issued one share of Series E Preferred Stock
to CBS Corporation ("CBS") in connection with the Advertising and Promotion and
License Agreements (Note I).

    The Series E Preferred Stock is voting. Additionally, the holder of the
Series E Preferred Stock, voting as a separate class, shall be entitled to
elect a certain number directors, depending on whether the license agreement
between CBS and Switchboard remains in effect and the percentage ownership in
Switchboard that CBS holds. The Series E Preferred Stock is convertible at any
time by CBS. The share of Series E Preferred Stock will automatically be
converted to one share of common stock (i) on the date both the license
agreement is no longer in effect and CBS's fully diluted ownership interest in
Switchboard equals zero; (ii) on the date a competitor of Switchboard acquires
a direct or indirect beneficial ownership interest of more than 30% of the
outstanding shares of common stock, or securities representing, in the
aggregate of more than 30% of the voting power of CBS, or all or substantially
all of CBS's assets; or (iii) the date on which the outstanding share of Series
E Preferred Stock is held by any person or entity other than CBS or its
affiliates. The Series E Preferred Stock is junior to the Series A, B, C and D
Preferred Stock with respect to redemption rights and the right to receive
either dividends or amounts distributable upon liquidation, dissolution or
winding up of Switchboard.

N. Stock Option Plans:

    In October 1999, Switchboard adopted the 1999 Stock Incentive Plan (the

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

    The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted-average
assumptions used for grants in each of the following periods:

<TABLE>

   Expected lives....................................... 7 years 6 years 5 years
</TABLE>

    The weighted average grant date fair values using the Black-Scholes option
pricing model were $1.17, $1.66 and $6.87 during the years ended December 31,
1997, 1998, and 1999, respectively. The effects of applying SFAS 123 in this
disclosure were not indicative of future amounts. Additional grants in future
years are anticipated.

    In 1999, the Board of Directors adopted the 1999 Employee Stock Purchase
Plan (the "Purchase Plan"). The Purchase Plan allows for the issuance of
300,000 shares of Switchboard's common stock to eligible employees. Under the
Purchase Plan, Switchboard is authorized to make a series of offerings during
which employees may purchase shares of common stock through payroll deductions
made over the term of the offering. The per-share purchase price at the end of
each offering is equal to 85% of the fair market value of the common stock at
the beginning or end of the offering period (as defined by the Purchase Plan),
whichever is lower.

O. Subsequent Event

    On January 28, 2000, the stockholders of Switchboard approved an amendment
to the 1999 Option Plan whereby the shares reserved for issuance were increased
by 375,000 to 1,875,000.

    On February 4, 2000, Switchboard filed a Certificate of Amendment to
Switchboard's Certificate of Incorporation to authorize an increase in the
capitalization of Switchboard from 30,000,000 to 85,000,000 shares of common
stock.

    At the top of the page is the heading "Advertising on Switchboard" set
against a purple background. The page is separated into three separate
vignettes, from top to bottom of the page. The caption, "Switchboard offers
customers a wide range of advertising options.", is centered above the
vignettes.

    The first vignette displays a snapshot of a yellow pages search query Web
page on the Switchboard Web site centered between two sets of captions and
text. To the left of the snapshot is the caption "Banner Advertising" which
serves as the heading for the text directly below it, "We offer site-wide,
category-specific and location-targeted banner programs." Two red arrows point
from that text to banner advertisements on the Web page snapshot. To the right
of the snapshot is the caption "Sponsor Advertising" which serves as the
heading for the text directly below it, "Our site-wide and category-specific
sponsorship consistently and prominently display ads on our Web site." A red
arrow points from the caption to sponsor advertisements on the Web page
snapshot.

    The second vignette displays a snapshot of a yellow pages search results
Web page on the Switchboard Web site. To the right of the snapshot is the
caption "Yellow Page Display Advertising" which serves as the heading for the
text directly below it, "We provide yellow pages-style display advertisements
which give advertisers a range of location, category and size options at the
local and national levels. Our display ads rotate to ensure that each
advertiser is periodically visible near the top of the page.". A red arrow
points from the text to the display advertisements on the Web page.

    The third vignette displays two snapshots of Web pages on the Switchboard
Web site. On the left is a snapshot of Switchboard's shopping area service.
Centered underneath that snapshot is the caption, "Switchboard Shopping Area".
On the right is a snapshot of a white pages search results Web page. Centered
underneath that snapshot is the caption, "Switchboard White Pages". Between the
two snapshots is the caption "E-Commerce Advertising" which serves as the
heading for the text directly below it, "We offer advertising options placed
near white pages search results and in our shopping area to e-commerce Web
sites.". Beneath that text are two red arrows, one pointing to each of the
snapshots.

Description of outside back cover:

    Centered in the top half of the page is a large yellow circle with a black
border. Inside the circle is the logo "Think outside the bookSM". Beneath that
logo within the circle in blue type with the CBS eye device in red is the logo
"CBS Switchboard.com". These logos are superimposed over the silhouette of a
person opening a door into a building. Beneath the circle centered slightly
below the middle of the page is the text "Switchboard has won numerous awards
since its launch:". A vignette appears below this text which includes four
pictures, from left to right across the page. The first picture is of the front
cover of Windows Magazine. Below that picture is the caption, ```101 Best
Business Sites', June 1, 1999 by Windows Magazine". The second picture is of a
logo for PC Magazine's top 100 Web sites in January 1999. Below that picture is

Item 14. Indemnification of Directors and Officers

    Article SEVENTH of the Registrant's amended and restated certificate of
incorporation provides that no director of the Registrant shall be personally
liable for any monetary damages for any breach of fiduciary duty as a director,
except to the extent that the Delaware General Corporation Law prohibits the
elimination or limitation of liability of directors for breach of fiduciary
duty.

    Article EIGHTH of the Registrant's amended and restated certificate of
incorporation provides that a director or officer of the Registrant:

    (a) shall be indemnified by the Registrant against all expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement incurred in
connection with any litigation or other legal proceeding (other than an action
by or in the right of the Registrant) brought against him by virtue of his
position as a director or officer of the Registrant if he acted in good faith
and in a manner he reasonably believed to be in, or not opposed to, the best
interests of the Registrant, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful and

    (b) shall be indemnified by the Registrant against all expenses (including
attorneys' fees) and amounts paid in settlement incurred in connection with any
action by or in the right of the Registrant brought against him by virtue of
his position as a director or officer of the Registrant if he acted in good
faith and in a manner he reasonably believed to be in, or not opposed to, the
best interests of the Registrant, except that no indemnification shall be made
with respect to any matter as to which such person shall have been adjudged to
be liable to the Registrant, unless a court determines that, despite such
adjudication but in view of all of the circumstances, he is entitled to
indemnification of such expenses.

    Notwithstanding the foregoing, to the extent that a director or officer has
been successful, on the merits or otherwise, including, without limitation, the
dismissal of an action without prejudice, he is required to be indemnified by
the Registrant against all expenses (including attorneys' fees) incurred in
connection therewith. Expenses shall be advanced to a director or officer at
his request, provided that he undertakes to repay the amount advanced if it is
ultimately determined that he is not entitled to indemnification for such
expenses.


                                      II-1
<PAGE>

    Indemnification is required to be made unless the Registrant determines
that the applicable standard of conduct required for indemnification has not
been met. In the event of a determination by the Registrant that the director
or officer did not meet the applicable standard of conduct required for
indemnification, or if the Registrant fails to make an indemnification payment
within 60 days after such payment is claimed by such person, such person is
permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification. As a condition precedent to
the right of indemnification, the director or officer must give the Registrant
notice of the action for which indemnity is sought and the Registrant has the
right to participate in such action or assume the defense thereof.

    Article EIGHTH of the Registrant's amended and restated certificate of
incorporation further provides that the indemnification provided therein is not
exclusive, and provides that in the event that the Delaware General Corporation
Law is amended to expand the indemnification permitted to directors or officers
the Registrant must indemnify those persons to the fullest extent permitted by
such law as so amended.

    Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent
of the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred in
connection with an action or proceeding to which he is or is threatened to be
made a party by reason of such position, if such person shall have acted in
good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, in any criminal proceeding, if such
person had no reasonable cause to believe his conduct was unlawful; provided
that, in the case of actions brought by or in the right of the corporation, no
indemnification shall be made with respect to any matter as to which such
person shall have been adjudged to be liable to the corporation unless and only
to the extent that the adjudicating court determines that such indemnification
is proper under the circumstances.

    Under the Underwriting Agreement, the underwriters are obligated, under
certain circumstances, to indemnify directors and officers of the Registrant
against certain liabilities, including liabilities under the Securities Act.
Reference is made to the form of Underwriting Agreement filed as Exhibit 1
hereto.

    pursuant to a Confidential Treatment Request.

(b) Financial Statement Schedules

    All other schedules have been omitted because they are not required or

financial statements or notes to those statements.

Item 17. Undertakings

    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions contained in the Amended and Restated
Certificate of Incorporation of the Registrant and the laws of the State of
Delaware, or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

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

                                      II-6

    The undersigned Registrant hereby undertakes that:

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

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

                             ______________ __, 2000


FleetBoston Robertson Stephens Inc.
J.P. Morgan Securities Inc.
The Robinson-Humphrey Company, LLC
Soundview Technology Group, Inc.
As Representatives of the several Underwriters
c/o FleetBoston Robertson Stephens Inc.
555 California Street, Suite 2600
San Francisco, CA  94104


Ladies and Gentlemen:

     INTRODUCTORY. Switchboard Incorporated, a Delaware corporation (the
"Company"), proposes to issue and sell to the several underwriters named in
Schedule A (the "Underwriters") an aggregate of [5,500,000] shares (the "Firm
Shares") of its Common Stock, par value $0.01 per share (the "Common Shares").
In addition, the Company has granted to the Underwriters an option to purchase
up to an additional [825,000] Common Shares (the "Option Shares") as provided in
Section 2. The Firm Shares and, if and to the extent such option is exercised,
the Option Shares are collectively called the "Shares". FleetBoston Robertson
Stephens Inc. ("Robertson Stephens"), J.P. Morgan Securities Inc., The Robinson-
Humphrey Company, LLC, and Soundview Technology Group, Inc have agreed to act as
representatives of the several Underwriters (in such capacity, the
"Representatives") in connection with the offering and sale of the Shares. As a
part of the offering contemplated by this Agreement, Robertson Stephens has
agreed to reserve out of the Shares set forth opposite its name on Schedule A to
this Agreement, up to [550,000] Shares, for sale to the Company's employees,
officers, and directors and other parties associated with the Company
(collectively, "Participants"), as set forth in the Prospectus under the heading
"Underwriting" (the "Directed Share Program"). The Shares to be sold by
Robertson Stephens pursuant to the Directed Share Program (the "Directed
Shares") will be sold by Robertson Stephens pursuant to this Agreement at the
public offering price. Any Directed Shares not orally confirmed for purchase by
any Participants as of 7:00 a.m., San Francisco time, on the first day trading
of the Shares commences will be offered to the public by Robertson Stephens as
set forth in the Prospectus.

     The Company has prepared and filed with the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-1 (File No.
333-90013), which contains a form of prospectus, subject to completion, to be
used

                                       1
<PAGE>

in connection with the public offering and sale of the Shares. The prospectus,
subject to completion, dated as of February __, 2000 to be used in connection
with such public offering is called the "Preliminary Prospectus." Such
registration statement, as amended, including the financial statements, exhibits
and schedules thereto, in the form in which it was declared effective by the
Commission under the Securities Act of 1933, and the rules and regulations
promulgated thereunder (collectively, the "Securities Act"), including any
information deemed to be a part thereof at the time of effectiveness pursuant to
Rule 430A under the Securities Act, is called the "Registration Statement". Any
registration statement filed by the Company pursuant to Rule 462(b) under the
Securities Act is called the "Rule 462(b) Registration Statement", and from and
after the date and time of filing of the Rule 462(b) Registration Statement the
term "Registration Statement" shall include the Rule 462(b) Registration
Statement. Such prospectus, in the form first used by the Underwriters to
confirm sales of the Shares, is called the "Prospectus". All references in this
Agreement to the Registration Statement, the Rule 462(b) Registration Statement,
the Preliminary Prospectus, the Prospectus, or any amendments or supplements to
any of the foregoing, shall include any copy thereof filed with the Commission
pursuant to its Electronic Data Gathering, Analysis and Retrieval System
("EDGAR").

     The Company hereby confirms its agreements with the Underwriters as
follows:

     SECTION 1.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

     The Company hereby represents, warrants and covenants to each Underwriter
as follows:

     (a) Compliance with Registration Requirements. The Registration Statement
and any Rule 462(b) Registration Statement have been declared effective by the
Commission under the Securities Act. The staff of the Commission has indicated
to the Company that all of its outstanding comments on the Registration
Statement have been resolved. No stop order suspending the effectiveness of the
Registration Statement or any Rule 462(b) Registration Statement is in effect
and no proceedings for such purpose have been instituted or are pending or, to
the best knowledge of the Company, are contemplated or threatened by the
Commission.

     The Preliminary Prospectus, as of its date, and the Prospectus when filed
complied in all material respects with the Securities Act and, if filed by
electronic transmission pursuant to EDGAR (except as may be permitted by
Regulation S-T under the Securities Act), was identical to the copy thereof
delivered to the Underwriters for use in connection with the offer and sale of
the Shares. Each of the Registration Statement, any Rule 462(b) Registration
Statement and any post-effective amendment thereto, at the time it became
effective and at all

                                       2
<PAGE>

subsequent times, complied and will comply in all material respects with the
Securities Act and did not and will not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading. The Preliminary
Prospectus, as of its date, and the Prospectus, as amended or supplemented, as
of its date and at all subsequent times, did not and will not contain any untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading. The representations and warranties set forth in
the two immediately preceding sentences do not apply to statements in or
omissions from the Registration Statement, any Rule 462(b) Registration
Statement, or any post-effective amendment thereto, or the Prospectus, or any
amendments or supplements thereto, made in reliance upon and in conformity with
information relating to any Underwriter furnished to the Company in writing by
the Representatives expressly for use therein. There are no contracts or other
documents required to be described in the Prospectus or to be filed as exhibits
to the Registration Statement which have not been described or filed as
required.

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

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

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

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

     (f) No Applicable Registration or Other Similar Rights . There are no
persons with registration or other similar rights to have any equity or debt
securities registered for sale under the Registration Statement or included in
the offering contemplated by this Agreement, except for such rights as have been
duly waived or have expired by reason of lapse of time following notification of
the Company's intent to file the Registration Statement.

                                       3
<PAGE>

     (g) No Material Adverse Change . Subsequent to the respective dates as of
which information is given in the Prospectus: (i) there has been no material
adverse change, or any development that could reasonably be expected to result
in a material adverse change, in the condition, financial or otherwise, or in
the earnings, business, operations or prospects, whether or not arising from
transactions in the ordinary course of business, of the Company (any such change
or effect, where the context so requires, is called a "Material Adverse Change"
or a "Material Adverse Effect"); (ii) the Company has not incurred any material
liability or obligation, indirect, direct or contingent, not in the ordinary
course of business nor entered into any material transaction or agreement not in
the ordinary course of business; and (iii) there has been no dividend or
distribution of any kind declared, paid or made by the Company.

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

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

     (j) Company's Accounting System. The Company maintains a system of
accounting controls sufficient to provide reasonable assurances that (i)
transactions are executed in accordance with management's general or specific
authorization; (ii) transactions are recorded as necessary to permit preparation
of financial statements in conformity with generally accepted accounting
principles and to maintain accountability for assets; (iii) access to assets is
permitted only in accordance with management's general or specific
authorization; and (iv) the recorded accountability for assets is compared with
existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

     (k)  Subsidiaries of the Company.  The Company has no subsidiaries.

                                       4
<PAGE>

     (l) Incorporation and Good Standing of the Company . The Company has been
duly organized and is validly existing as a corporation in good standing under
the laws of the jurisdiction in which it is organized with full corporate power
and authority to own its properties and conduct its business as described in the
Prospectus, and is duly qualified to do business as a foreign corporation and is
in good standing under the laws of each jurisdiction which requires such
qualification, except where failure or failures to qualify, individually or in
the aggregate, would not have a Material Adverse Effect.

     (m) Capitalization and Other Capital Stock Matters . The authorized, issued
and outstanding capital stock of the Company is as set forth in the Prospectus
under the caption "Capitalization" (other than for subsequent issuances, if any,
pursuant to employee benefit plans described in the Prospectus or upon exercise
of outstanding options, warrants or convertible securities described in the
Prospectus). The Common Shares (including the Shares) conform in all material
respects to the description thereof contained in the Prospectus. All of the
issued and outstanding Common Shares have been duly authorized and validly
issued, are fully paid and nonassessable and have been issued in compliance with
federal and state securities laws. None of the outstanding Common Shares was
issued in violation of any preemptive rights, rights of first refusal or other
similar rights to subscribe for or purchase securities of the Company. There are
no authorized or outstanding options, warrants, preemptive rights, rights of
first refusal or other rights to purchase, or equity or debt securities
convertible into or exchangeable or exercisable for, any capital stock of the
Company issued or granted by the Company, as the case may be, other than those
described in the Prospectus. The description of the Company's stock option,
stock bonus and other stock plans or arrangements, and the options or other
rights granted thereunder, set forth in the Prospectus accurately and fairly
presents the information required to be shown with respect to such plans,
arrangements, options and rights.

     (n) Stock Exchange Listing . The Shares have been approved for inclusion on
the Nasdaq National Market, subject only to official notice of issuance.

     (o) No Consents, Approvals or Authorizations Required . No consent,
approval, authorization, filing with or order of any court or governmental
agency or regulatory body is required in connection with the transactions
contemplated herein, except such as have been obtained or made under the
Securities Act and such as may be required (i) under the blue sky laws of any
jurisdiction in connection with the purchase and distribution of the Shares by
the Underwriters in the manner contemplated herein and in the Prospectus, (ii)
by the National Association of Securities Dealers, LLC and (iii) by the federal
and provincial laws of Canada.

     (p) Non-Contravention of Existing Instruments and Agreements . Neither the
issue and sale of the Shares nor the consummation of any other of the
transactions herein contemplated nor the fulfillment of the terms hereof will
conflict with, result in a breach or violation or imposition of any lien, charge
or encumbrance upon any property or assets of the Company pursuant to, (i) the
charter or by-laws of the Company, (ii) the terms of any indenture, contract,
lease, mortgage, deed of trust, note agreement, loan agreement or

                                       5
<PAGE>

other agreement, obligation, condition, covenant or instrument to which the
Company is a party or bound or to which its property is subject, except in any
case or cases where such conflicts, breaches, violations or impositions would
not, individually or in the aggregate, result in a Material Adverse Effect or
(iii) any statute, law, rule, regulation, judgment, order or decree applicable
to the Company of any court, regulatory body, administrative agency,
governmental body, arbitrator or other authority having jurisdiction over the
Company or any of its properties.

     (q) No Defaults or Violations . The Company is not in violation or default
of (i) any provision of its charter or by-laws, (ii) the terms of any indenture,
contract, lease, mortgage, deed of trust, note agreement, loan agreement or
other agreement, obligation, condition, covenant or instrument to which it is a
party or bound or to which its property is subject or (iii) any statute, law,
rule, regulation, judgment, order or decree of any court, regulatory body,
administrative agency, governmental body, arbitrator or other authority having
jurisdiction over the Company or any of its properties, as applicable, except
any such violations or defaults which would not, singly or in the aggregate,
result in a Material Adverse Change except as otherwise disclosed in the
Prospectus.

     (r) No Actions, Suits or Proceedings . No action, suit or proceeding by or
before any court or governmental agency, authority or body or any arbitrator
involving the Company or its property is pending or, to the best knowledge of
the Company, threatened that (i) could reasonably be expected to have a Material
Adverse Effect on the performance of this Agreement or the consummation of any
of the transactions contemplated hereby or (ii) could reasonably be expected to
result in a Material Adverse Effect.

     (s) All Necessary Permits, Etc . The Company possesses such valid and
current certificates, authorizations or permits issued by the appropriate state,
federal or foreign regulatory agencies or bodies necessary to conduct its
businesses except where any failure or failures to possess such certificate,
authorization or permit, singly or in the aggregate, would not result in a
Material Adverse Effect, and the Company has not received any notice of
proceedings relating to the revocation or modification of, or non-compliance
with, any such certificates, authorizations or permits which, singly or in the
aggregate, if the subject of an unfavorable decision, ruling or finding, could
result in a Material Adverse Change.

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

                                       6
<PAGE>

made of such real property, improvements, equipment or personal property by the
Company.

     (u) Tax Law Compliance . The Company has filed all necessary federal, state
and foreign income and franchise tax returns or has properly requested
extensions thereof and has paid all taxes required to be paid by it and, if due
and payable, any related or similar assessment, fine or penalty levied against
it, except where any failure or failures to file or pay, individually or in the
aggregate, would not have a Material Adverse Effect. The Company has made
adequate charges, accruals and reserves in the applicable financial statements
referred to in Section 1(i) above in respect of all federal, state and foreign
income and franchise taxes for all periods as to which the tax liability of the
Company has not been finally determined. The Company is not aware of any tax
deficiency that has been or might be asserted or threatened against the Company
that could result in a Material Adverse Change.

     (v) Intellectual Property Rights . The Company owns or possesses adequate
rights to use all patents, patent rights or licenses, inventions, collaborative
research agreements, trade secrets, know-how, trademarks, service marks, trade
names and copyrights which are necessary to conduct its businesses as described
in the Registration Statement and Prospectus. None of the Company's software
that it owns includes or incorporates any code obtained from the public domain
or from open source software. The expiration of any patents, patent rights,
trade secrets, trademarks, service marks, trade names or copyrights owned,
possessed or licensed by the Company would not reasonably be expected to result
in a Material Adverse Change that is not otherwise disclosed in the Prospectus;
the Company has not received any notice of, and has no knowledge of, any
infringement of or conflict with asserted rights of the Company by others with
respect to any patent, patent rights, inventions, trade secrets, know-how,
trademarks, service marks, trade names or copyrights; and the Company has not
received any notice of, and has no knowledge of, any infringement of or conflict
with asserted rights of others with respect to any patent, patent rights,
inventions, trade secrets, know-how, trademarks, service marks, trade names or
copyrights which, singly or in the aggregate, if the subject of an unfavorable
decision, ruling or finding, might have a Material Adverse Effect. There is no
claim being made against the Company regarding patents, patent rights or
licenses, inventions, collaborative research, trade secrets, know-how,
trademarks, service marks, trade names or copyrights. The Company does not in
the conduct of its business as described in the Prospectus infringe or conflict
with any right or patent of any third party, or any discovery, invention,
product or process which is the subject of a patent application filed by any
third party, known to the Company, which such infringement or conflict is
reasonably likely to result in a Material Adverse Change.

     (w) Year 2000 Preparedness . There are no issues related to the Company's
readiness for the "Year 2000 Problem," as described in the Prospectus, that (i)
are of a character required to be described or referred to in the Registration
Statement or Prospectus by the Securities Act which have not been accurately
described in the Registration Statement or Prospectus or (ii) might reasonably
be expected to result in any Material Adverse Change. All internal computer
systems and each Constituent

                                       7
<PAGE>

Component (as defined below) of those systems of the Company fully comply with
Year 2000 Qualification Requirements (as defined below). "Year 2000
Qualifications Requirements" means that the internal computer systems and each
Constituent Component of those systems s of the Company (i) have been designed
to ensure date and time entry recognition and calculations, and date data
interface values that reflect the century, (ii) accurately manage and manipulate
data involving dates and times, including single century formulas and
multi-century formulas, and will not cause an abnormal ending scenario within
the application or generate incorrect values or invalid results involving such
dates, (iii) accurately process any date rollover, and (iv) accept and respond
to two-digit year date input in a manner that resolves any ambiguities as to the
century. "Constituent Component" means all software (including operating
systems, programs, packages and utilities), firmware, hardware, networking
components, and peripherals provided as part of the configuration. The Company
has inquired of material vendors as to their preparedness for the Year 2000 and
has disclosed in the Registration Statement or Prospectus any issues that might
reasonably be expected to result in any Material Adverse Change.

     (x) No Transfer Taxes or Other Fees . There are no transfer taxes or other
similar fees or charges under federal law or the laws of any state, or any
political subdivision thereof, required to be paid in connection with the
execution and delivery of this Agreement or the issuance and sale by the Company
of the Shares.

     (y) Company Not an "Investment Company" {. The Company has been advised of
the rules and requirements under the Investment Company Act of 1940, as amended
(the "Investment Company Act"). The Company is not, and after receipt of payment
for the Shares will not be, an "investment company" or an entity "controlled" by
an "investment company" within the meaning of the Investment Company Act and
will conduct its business in a manner so that it will not become subject to the
Investment Company Act.

     (z) Insurance . The Company is insured by nationally recognized
institutions with policies held by the Company and in the Company's name in such
amounts and with such deductibles and covering such risks as are generally
deemed adequate and customary for its business including, but not limited to,
policies covering real and personal property owned or leased by the Company
against theft, damage, destruction, acts of vandalism and earthquakes, general
liability and Directors and Officers liability; and none of such policies will
terminate as a result of the issuance of the Shares. The Company has no reason
to believe that it will not be able (i) to renew its existing insurance coverage
as and when such policies expire or (ii) to obtain comparable coverage from
similar institutions as may be necessary or appropriate to conduct its
businesses as now conducted and at a cost that would not result in a Material
Adverse Change. The Company has not been denied any insurance coverage which it
has sought or for which it has applied.

     (aa) Labor Matters . To the best of Company's knowledge, no labor
disturbance by the employees of the Company exists or is imminent; and the
Company is

                                       8
<PAGE>

not aware of any existing or imminent labor disturbance by the employees of
Banyan Systems Incorporated ("Banyan Worldwide") or any other of the Company's
material suppliers that could reasonably be expected to result in a Material
Adverse Change.

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

     (cc) Lock-Up Agreements . Each officer and director of the Company and each
securityholder of the Company has agreed to sign an agreement substantially in
the form attached hereto as Exhibit A or is party to an agreement with the
                            ---------
Company that such holder will not sell Common Shares within 180 days of the date
hereof without the consent of the Company (the "Lock-up Agreements"). The
Company has provided to counsel for the Underwriters a complete and accurate
list of all securityholders of the Company and the number and type of securities
held by each securityholder. The Company has provided to counsel for the
Underwriters true, accurate and complete copies of all of the Lock-up Agreements
presently in effect or effected hereby. The Company hereby represents and
warrants that it will not release any of its officers, directors or other
securityholders from any Lock-up Agreements currently existing or hereafter
effected without the prior written consent of Robertson Stephens.

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

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

     (ff) Environmental Laws . (i) the Company is in compliance with all rules,
laws and regulations relating to the use, treatment, storage and disposal of
toxic substances and protection of health or the environment ("Environmental
Laws") which are applicable to its business, except where the failure to comply
would not result in a Material Adverse Change, (ii) the Company has received no
notice from any governmental authority or third party of an asserted claim under

Statement and the Prospectus, (iii) the Company is not currently aware that it
will be required to make future material capital expenditures to comply with
Environmental Laws and (iv) no property which is owned, leased or occupied by

     (gg) ERISA Compliance . The Company and any "employee benefit plan" (as
defined under the Employee Retirement Income Security Act of 1974, as amended,
and the regulations and published interpretations thereunder (collectively,
"ERISA")) established or maintained by the Company or its "ERISA Affiliates" (as
defined below) are in compliance in all material respects with ERISA. "ERISA
Affiliate" means, with respect to the Company, any member of any group of
organizations described in Sections 414(b),(c),(m) or (o) of the Internal
Revenue Code of 1986, as amended, and the regulations and published
interpretations thereunder (the "Code") of which the Company is a member. No
"reportable event" (as defined under ERISA) has occurred or is reasonably
expected to occur with respect to any "employee benefit plan" established or
maintained by the Company or any of its ERISA Affiliates. No "employee benefit
plan" established or maintained by the Company or any of its ERISA Affiliates,
if such "employee benefit plan" were terminated, would have any "amount of
unfunded benefit liabilities" (as defined under ERISA). Neither the Company nor
any of its ERISA Affiliates has incurred or reasonably expects to incur any
liability under (i) Title IV of ERISA with respect to termination of, or
withdrawal from, any "employee benefit plan" or (ii) Sections 412, 4971, 4975 or
4980B of the Code. Each "employee benefit plan" established or maintained by the
Company or any of ERISA Affiliates that is intended to be qualified under
Section 401(a) of the Code is so qualified and nothing has occurred, whether by
action or failure to act, which would cause the loss of such qualification.

     (hh) Consents Required in Connection with the Directed Share Program. No
consent, approval, authorization or order of, or qualification with, any
governmental body or agency, other than those obtained, is required in
connection with the offering of the Directed Shares in any jurisdiction where
the Directed Shares are being offered.

     (ii) No Improper Influence in Connection with the Directed Share Program.
The Company has not offered, or caused Robertson Stephens to offer, Shares to
any person pursuant to the Directed Share Program with the specific intent to
unlawfully influence (i) a customer or supplier of the Company to alter the
customer's or supplier's level or type of business with the Company or (ii) a
trade journalist or publication to write or publish favorable information about
the Company or its products.

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

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

     (a) The Firm Shares . The Company agrees to issue and sell to the several
Underwriters the Firm Shares upon the terms herein set forth. On the basis of
the representations, warranties and agreements herein contained, and upon the
terms but subject to the conditions herein set forth, the Underwriters agree,
severally and not jointly, to purchase from the Company the respective number of
Firm Shares set forth opposite their names on Schedule A. The purchase price per
                                              ----------
Firm Share to be paid by the several Underwriters to the Company shall be $___
per share.

<PAGE>

     (b) The First Closing Date . Delivery of the Firm Shares to be purchased by
the Underwriters and payment therefor shall be made by the Company and the
Representatives at 6:00 a.m., San Francisco time, at the offices of Hale and
Dorr LLP, 60 State Street, Boston, Massachusetts 02109 (or at such other place
or time as may be agreed upon among the Representatives and the Company), (i) on
the third (3rd) full business day following the first day that Shares are
traded, (ii) if this Agreement is executed and delivered after 1:30 p.m., San
Francisco time, the fourth (4th) full business day following the day that this
Agreement is executed and delivered or (iii) at such other time and date not
later that seven (7) full business days following the first day that Shares are
traded as the Representatives and the Company may determine (or at such time and
date to which payment and delivery shall have been postponed pursuant to Section
8 hereof), such time and date of payment and delivery being herein called the
"Closing Date;" provided, however, that if the Company has not made available to
the Representatives copies of the Prospectus within the time provided in
Sections 2(g) and 3(e) hereof, the Representatives may, in their sole
discretion, postpone the Closing Date until no later that two (2) full business
days following delivery of copies of the Prospectus to the Representatives.

     (c) The Option Shares; the Second Closing Date . In addition, on the basis
of the representations, warranties and agreements herein contained, and upon the
terms but subject to the conditions herein set forth, the Company hereby grants
an option to the several Underwriters to purchase, severally and not jointly, up
to an aggregate of [825,000] Option Shares from the Company at the purchase
price per share to be paid by the Underwriters for the Firm Shares. The option
granted hereunder is for use by the Underwriters solely in covering any
over-allotments in connection with the sale and distribution of the Firm Shares.
The option granted hereunder may be exercised at any time upon notice by the
Representatives to the Company, which notice may be given at any time within 30
days from the date of this Agreement. The time and date of delivery of the
Option Shares, if subsequent to the First Closing Date, is called the "Second
Closing Date" and shall be determined by the Representatives and shall not be
earlier than three nor later than five full business days after delivery of such
notice of exercise. If any Option Shares are to be purchased, each Underwriter
agrees, severally and not jointly, to purchase the number of Option Shares
(subject to such adjustments to eliminate fractional shares as the
Representatives may determine) that bears the same proportion to the total
number of Option Shares to be purchased as the number of Firm Shares set forth
on Schedule A opposite the name of such Underwriter bears to the total number of
   ----------
Firm Shares. The Representatives may cancel the option at any time prior to its
expiration by giving written notice of such cancellation to the Company.

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

                                       11
<PAGE>

     (e) Payment for the Shares . Payment for the Shares shall be made at the
First Closing Date (and, if applicable, at the Second Closing Date) by wire
transfer in immediately available-funds to an account designated by the Company.

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

     (f) Delivery of the Shares . The Company shall deliver, or cause to be
delivered, a credit representing the Firm Shares to an account or accounts at
The Depository Trust Company, as designated by the Representatives for the
accounts of the Representatives and the several Underwriters at the First
Closing Date, against the irrevocable release of a wire transfer to an account
designated by the Company of immediately available funds for the amount of the
purchase price therefor. The Company shall also deliver, or cause to be
delivered a credit representing the Option Shares the Underwriters have agreed
to purchase at the First Closing Date (or the Second Closing Date, as the case
may be), to an account or accounts at The Depository Trust Company as designated
by the Representatives for the accounts of the Representatives and the several
Underwriters, against the irrevocable release of a wire transfer to an account
designated by the Company of immediately available funds for the amount of the
purchase price therefor. Time shall be of the essence, and delivery at the time
and place specified in this Agreement is a further condition to the obligations
of the Underwriters.

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

     SECTION 3.  COVENANTS OF THE COMPANY.

     The Company further covenants and agrees with each Underwriter as follows:

    (a) Registration Statement Matters . The Company will (i) use its best
efforts to cause a registration statement on Form 8-A (the "Form 8-A
Registration Statement") as required by the Securities Exchange Act of 1934 (the
"Exchange Act") to become effective simultaneously with the Registration
Statement, (ii) use its best efforts to cause the Registration Statement to
become effective or, if the procedure in Rule 430A of the Securities Act is
followed, to prepare and timely file with the Commission under Rule 424(b) under
the Securities Act a Prospectus in a form approved by the Representatives

                                       12
<PAGE>

containing information previously omitted at the time of effectiveness of the
Registration Statement in reliance on Rule 430A of the Securities Act and (iii)
not file any amendment to the Registration Statement or supplement to the
Prospectus of which the Representatives shall not previously have been advised
and furnished with a copy or to which the Representatives shall have reasonably
objected in writing or which is not in compliance with the Securities Act. If
the Company elects to rely on Rule 462(b) under the Securities Act, the Company
shall file a Rule 462(b) Registration Statement with the Commission in
compliance with Rule 462(b) under the Securities Act prior to the time
confirmations are sent or given, as specified by Rule 462(b)(2) under the
Securities Act, and shall pay the applicable fees in accordance with Rule 111
under the Securities Act.

     (b) Securities Act Compliance . The Company will advise the Representatives
promptly (i) when the Registration Statement or any post- effective amendment
thereto shall have become effective, (ii) of receipt of any comments from the
Commission, (iii) of any request of the Commission for amendment of the
Registration Statement or for supplement to the Prospectus or for any additional
information and (iv) of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement or the use of the
Prospectus or of the institution of any proceedings for that purpose. The
Company will use its best efforts to prevent the issuance of any such stop order
preventing or suspending the use of the Prospectus and to obtain as soon as
possible the lifting thereof, if issued.

     (c) Blue Sky Compliance . The Company will cooperate with the
Representatives and counsel for the Underwriters in endeavoring to qualify the
Shares for sale under the securities laws of such jurisdictions (both national
and foreign) as the Representatives may reasonably have designated in writing
and will make such applications, file such documents, and furnish such
information as may be reasonably required for that purpose, provided the Company
shall not be required to qualify as a foreign corporation or to file a general
consent to service of process in any jurisdiction where it is not now so
qualified or required to file such a consent. The Company will, from time to
time, prepare and file such statements, reports and other documents, as are or
may be required to continue such qualifications in effect for so long a period
as the Representatives may reasonably request for distribution of the Shares.

     (d) Amendments and Supplements to the Prospectus and Other Securities Act
Matters . The Company will comply with the Securities Act and the Exchange Act,
and the rules and regulations of the Commission thereunder, so as to permit the
completion of the distribution of the Shares as contemplated in this Agreement
and the Prospectus. If during the period in which a prospectus is required by
law to be delivered by an Underwriter or dealer, any event shall occur as a
result of which, in the judgment of the Company or in the reasonable opinion of
the Representatives or counsel for the Underwriters, it becomes necessary to
amend or supplement the Prospectus in order to make the statements therein, in
the light of the circumstances existing at the time the Prospectus is delivered
to a purchaser, not misleading, or, if it is necessary at any time to amend or
supplement the Prospectus to comply with any law, the Company promptly will
prepare and file with the Commission, and furnish at its own expense to the
Underwriters

                                       13
<PAGE>

and to dealers, an appropriate amendment to the Registration Statement or
supplement to the Prospectus so that the Prospectus as so amended or
supplemented will not, in the light of the circumstances when it is so
delivered, be misleading, or so that the Prospectus will comply with the law.

     (e) Copies of any Amendments and Supplements to the Prospectus . The
Company agrees to furnish the Representatives, without charge, during the period
beginning on the date hereof and ending on the later of the First Closing Date
or such date, as in the opinion of counsel for the Underwriters, the Prospectus
is no longer required by law to be delivered in connection with sales by an
Underwriter or dealer (the "Prospectus Delivery Period"), as many copies of the
Prospectus and any amendments and supplements thereto as the Representatives may
request.

     (f) Insurance. The Company shall obtain Directors and Officers liability
insurance in the minimum amount of $10 million which shall apply to the offering
contemplated hereby.

     (g) Notice of Subsequent Events . If at any time during the ninety (90) day
period after the Registration Statement becomes effective, any rumor,
publication or event relating to or affecting the Company shall occur as a
result of which in your opinion the market price of the Company Shares has been
or is likely to be materially affected (regardless of whether such rumor,
publication or event necessitates a supplement to or amendment of the
Prospectus), the Company will, after written notice from you advising the
Company to the effect set forth above, forthwith prepare, consult with you
concerning the substance of and disseminate a press release or other public
statement, reasonably satisfactory to you, responding to or commenting on such
rumor, publication or event.

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

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

     (j) Earnings Statement . As soon as practicable, but no later than [May 15,
2001], the Company will make generally available to its security holders and to
the Representatives an earnings statement (which need not be audited) covering
the twelve-month period ending [March 31, 2001] that satisfies the provisions of
Section 11(a) of the Securities Act.

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

     (l) Agreement Not to Offer or Sell Additional Securities . The Company will
not, without the prior written consent of Robertson Stephens, for a period of
180 days

                                       14
<PAGE>

following the date of the Prospectus, offer, sell or contract to sell, or
otherwise dispose of or enter into any transaction which is designed to, or
could be expected to, result in the disposition (whether by actual disposition
or effective economic disposition due to cash settlement or otherwise by the
Company, any affiliate of the Company or any person in privity with the Company
or any affiliate of the Company) directly or indirectly, or announce the
offering of, any other Common Shares or any securities convertible into, or
exchangeable for, Common Shares; provided, however, that the Company may (i)
issue and sell Common Shares pursuant to any director or employee stock option
plan, stock ownership plan or dividend reinvestment plan of the Company in
effect at the date of the Prospectus and described in the Prospectus so long as
none of those shares may be transferred during the period of 180 days from the
date that the Registration Statement is declared effective (the "Lock-Up
Period") and the Company shall enter stop transfer instructions with its
transfer agent and registrar against the transfer of any such Common Shares,
(ii) issue Common Shares issuable upon the conversion of securities or the
exercise of warrants outstanding at the date of the Prospectus and described in
the Prospectus and the Company shall enter stop transfer instructions with its
transfer agent and registrar against the transfer of any such Common Shares
issued to a party to a Lock-Up Agreement and (iii) issue and sell the Shares
pursuant to the terms of this Agreement.

     (m) Future Reports to the Representatives . During the period of three
years hereafter the Company will furnish to the Representatives (i) as soon as
practicable after the end of each fiscal year, copies of the Annual Report of
the Company containing the balance sheet of the Company as of the close of such
fiscal year and statements of income, stockholders' equity and cash flows for
the year then ended and the opinion thereon of the Company's independent public
or certified public accountants; (ii) as soon as practicable after the filing
thereof, copies of each proxy statement, Annual Report on Form 10-K, Quarterly
Report on Form 10-Q, Current Report on Form 8-K or other report filed by the
Company with the Commission, the National Association of Securities Dealers, LLC
or any securities exchange; and (iii) as soon as available, copies of any report
or communication of the Company mailed generally to holders of its capital
stock.

     (n) Directed Share Program. The Company (i) will indemnify Robertson
Stephens for any losses incurred in connection with the Directed Share Program,
(ii) will comply with all applicable securities and other applicable laws, rules
and regulations in each jurisdiction in which the Directed Shares are offered in
connection with the Directed Share Program and (iii) will pay all reasonable
fees and disbursements of counsel incurred by the Underwriters in connection
with the Directed Share Program and any stamp duties, similar taxes or duties or
other taxes, if any, incurred by the underwriters in connection with the
Directed Share Program.

     SECTION 4. CONDITIONS OF THE OBLIGATIONS OF THE UNDERWRITERS. The
obligations of the several Underwriters to purchase and pay for the Shares as
provided herein on the First Closing Date and, with respect to the Option
Shares, the Second Closing Date, shall be subject to the accuracy of the
representations and warranties on the part of the Company set forth in Section 1
hereof as of the date hereof and as of the First Closing Date as though then
made and, with respect to the Option Shares, as of the Second Closing

                                       15
<PAGE>

Date as though then made, to the timely performance by the Company of its
covenants and other obligations hereunder, and to each of the following
additional conditions:

    (a) Compliance with Registration Requirements; No Stop Order; No Objection
from the National Association of Securities Dealers, LLC. The Registration
Statement shall have become effective prior to the execution of this Agreement,
or at such later date as shall be consented to in writing by you; and no stop
order suspending the effectiveness thereof shall have been issued and no
proceedings for that purpose shall have been initiated or, to the knowledge of
the Company or any Underwriter, threatened by the Commission, and any request of
the Commission for additional information (to be included in the Registration
Statement or the Prospectus or otherwise) shall have been complied with to the
satisfaction of Underwriters' counsel; and the National Association of
Securities Dealers, LLC shall have raised no objection to the fairness and
reasonableness of the underwriting terms and arrangements.

    (b) Corporate Proceedings . All corporate proceedings and other legal
matters in connection with this Agreement, the form of Registration Statement
and the Prospectus, and the registration, authorization, issue, sale and
delivery of the Shares, shall have been reasonably satisfactory to Underwriters'
counsel, and such counsel shall have been furnished with such papers and
information as they may reasonably have requested to enable them to pass upon
the matters referred to in this Section.

    (c) No Material Adverse Change. Subsequent to the execution and delivery of
this Agreement and prior to the First Closing Date, or the Second Closing Date,
as the case may be, there shall not have been any Material Adverse Change in the
condition (financial or otherwise), earnings, operations, business or business
prospects of the Company from that set forth in the Registration Statement or
Prospectus, which, in your sole judgment, is material and adverse and that makes
it, in your sole judgment, impracticable or inadvisable to proceed with the
public offering of the Shares as contemplated by the Prospectus.

    (d) Opinion of Counsel for the Company . You shall have received on the
First Closing Date, or the Second Closing Date, as the case may be, an opinion
of Hale and Dorr LLP, counsel for the Company, as to the matters identified on
Exhibit B attached hereto, dated the First Closing Date, or the Second Closing
- ---------
Date, addressed to the Underwriters and with reproduced copies or signed
counterparts thereof for each of the Underwriters.

    Counsel rendering the opinion contained in Exhibit B may rely as to
                                               ---------
questions of law not involving the laws of the United States or the Commonwealth
of Massachusetts and the State of Delaware upon opinions of local counsel, and
as to questions of fact upon representations or certificates of officers of the
Company, and of government officials, in which case their opinion is to state
that they are so relying and that they have no knowledge of any material
misstatement or inaccuracy in any such opinion, representation or certificate.
Copies of any opinion, representation or certificate so relied upon shall be
delivered to you, as Representatives of the Underwriters, and to Underwriters'
Counsel.

                                       16
<PAGE>

    (e) Opinion of Counsel for the Underwriters . You shall have received on the
First Closing Date or the Second Closing Date, as the case may be, an opinion of
Testa, Hurwitz & Thibeault, LLP, as to the matters identified on Exhibit C
                                                                 ---------
hereto. The Company shall have furnished to such counsel such documents as they
may have requested for the purpose of enabling them to pass upon such matters.

    (f) Accountants' Comfort Letter '. You shall have received on the First
Closing Date and on the Second Closing Date, as the case may be, a letter from
PricewaterhouseCoopers LLP addressed to the Underwriters, dated the First
Closing Date or the Second Closing Date, as the case may be, confirming that
they are independent certified public accountants with respect to the Company
within the meaning of the Securities Act and the applicable published Rules and
Regulations and based upon the procedures described in such letter delivered to
you concurrently with the execution of this Agreement (herein called the
"Original Letter"), but carried out to a date not more than four (4) business
days prior to the First Closing Date or the Second Closing Date, as the case may
be, (i) confirming, to the extent true, that the statements and conclusions set
forth in the Original Letter are accurate as of the First Closing Date or the
Second Closing Date, as the case may be, and (ii) setting forth any revisions
and additions to the statements and conclusions set forth in the Original Letter
which are necessary to reflect any changes in the facts described in the
Original Letter since the date of such letter, or to reflect the availability of
more recent financial statements, data or information. The letter shall not
disclose any change in the condition (financial or otherwise), earnings,
operations, business or business prospects of the Company from that set forth in
the Registration Statement or Prospectus, which, in your sole judgment, is
material and adverse and that makes it, in your sole judgment, impracticable or
inadvisable to proceed with the public offering of the Shares as contemplated by
the Prospectus. The Original Letter from PricewaterhouseCoopers LLP shall be
addressed to or for the use of the Underwriters in form and substance
satisfactory to the Underwriters and shall (i) represent, to the extent true,
that they are independent certified public accountants with respect to the
Company within the meaning of the Act and the applicable published Rules and
Regulations, (ii) set forth their opinion with respect to their examination of
the balance sheet of the Company as of December 31, 1999 and related statements
of operations, shareholders' equity, and cash flows for the twelve (12) months
ended December 31, 1999, (iii) state that PricewaterhouseCoopers LLP has
performed the procedures set out in Statement on Auditing Standards No. 71 ("SAS
71") for a review of interim financial information and providing the report of
PricewaterhouseCoopers LLP as described in SAS 71 on the financial statements
for each of the quarters in the eight-quarter period ended December 31, 1999
(the "Quarterly Financial Statements"), (iv) state that in the course of such
review, nothing came to their attention that leads them to believe that any
material modifications need to be made to any of the Quarterly Financial
Statements in order for them to be in compliance with generally accepted
accounting principles consistently applied across the periods presented, and
address other matters agreed upon by PricewaterhouseCoopers LLP and you. In
addition, you shall have received from PricewaterhouseCoopers LLP a letter
addressed to the Company and made available to you for the use of the
Underwriters stating that their review of the Company's system of internal

                                       17
<PAGE>

accounting controls, to the extent they deemed necessary in establishing the
scope of their examination of the Company's financial statements as of December
31, 1999, did not disclose any weaknesses in internal controls that they
considered to be material weaknesses.

    (g) Officers' Certificate '. You shall have received on the First Closing
Date and the Second Closing Date, as the case may be, a certificate of the
Company, dated the First Closing Date or the Second Closing Date, as the case
may be, signed by the Chief Executive Officer or President and the Chief
Financial Officer of the Company, to the effect that, and you shall be satisfied
that:

    (i) The representations and warranties of the Company in this Agreement are
    true and correct, as if made on and as of the First Closing Date or the
    Second Closing Date, as the case may be, and the Company has complied with
    all the agreements and satisfied all the conditions on its part to be
    performed or satisfied at or prior to the First Closing Date or the Second
    Closing Date, as the case may be;

    (ii) No stop order suspending the effectiveness of the Registration
    Statement has been issued and no proceedings for that purpose have been
    instituted or are pending or, to the Company's knowledge, threatened under
    the Securities Act;

    (iii) When the Registration Statement became effective and at all times
    subsequent thereto up to the delivery of such certificate, the Registration
    Statement and the Prospectus, and any amendments or supplements thereto
    contained all material information required to be included therein by the
    Securities Act and in all material respects conformed to the requirements of
    the Securities Act; the Registration Statement and the Prospectus, and any
    amendments or supplements thereto, did not and do not include any untrue
    statement of a material fact or omit to state a material fact required to be
    stated therein or necessary to make the statements therein not misleading;
    and, since the effective date of the Registration Statement, there has
    occurred no event required to be set forth in an amended or supplemented
    Prospectus which has not been so set forth; and

    (iv) Subsequent to the respective dates as of which information is given in
    the Registration Statement and Prospectus, there has not been (a) any
    Material Adverse Change (b) any transaction that is material to the Company,
    except transactions entered into in the ordinary course of business, (c) any
    obligation, direct or contingent, that is material to the Company, incurred
    by the Company, except obligations incurred in the ordinary course of
    business, (d) any change in the capital stock or outstanding indebtedness of
    the Company that is material to the Company, except for the issuance of
    Common Shares pursuant to the exercise of options or warrants described in
    the Prospectus, or conversion of convertible securities, described in the
    Prospectus and the issuance of Shares to the Underwriters pursuant to the
    terms of this Agreement, (e) any dividend or distribution of any kind

themselves), severally, upon demand for all out-of-pocket expenses that shall
have been reasonably incurred by the Representatives and the Underwriters in
connection with the proposed purchase and the offering and sale of the Shares,
including but not limited to fees and disbursements of counsel, printing
expenses, travel and accommodation expenses, postage, facsimile and telephone

    SECTION 7.  INDEMNIFICATION AND CONTRIBUTION.

     (a) Indemnification of the Underwriters . The Company agrees to indemnify
and hold harmless each Underwriter, its officers and employees, and each person,
if any, who controls any Underwriter within the meaning of the Securities Act
and the Exchange Act against any loss, claim, damage, liability or expense, as
incurred, to which such Underwriter or such controlling person may become
subject, under the Securities Act, the Exchange Act or other federal or state
statutory law or regulation, or at common law or otherwise (including in
settlement of any litigation, if such settlement is effected with the written
consent of the Company, which consent shall not be unreasonably withheld),
insofar as such loss, claim, damage, liability or expense (or actions in respect
thereof as contemplated below) arises out of or is based (i) upon any untrue
statement or alleged

                                       20
<PAGE>

untrue statement of a material fact contained in the Registration Statement, or
any amendment thereto, including any information deemed to be a part thereof
pursuant to Rule 430A under the Securities Act, or the omission or alleged
omission therefrom of a material fact required to be stated therein or necessary
to make the statements therein not misleading; or (ii) upon any untrue statement
or alleged untrue statement of a material fact contained in any preliminary
prospectus or the Prospectus (or any amendment or supplement thereto), or the
omission or alleged omission therefrom of a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; or (iii) in whole or in part upon any inaccuracy in
the representations and warranties of the Company contained herein; or (iv) in
whole or in part upon any failure of the Company to perform its obligations
hereunder or under law; or (v) any untrue statement or alleged untrue statement
of any material fact contained in any audio or visual materials provided by the
Company or based upon written information furnished by or on behalf of the
Company including, without limitation, slides, videos, films or tape recordings,
used in connection with the marketing of the Shares, including without
limitation, statements communicated to securities analysts employed by the
Underwriters; or (vi) any act or failure to act or any alleged act or failure to
act by any Underwriter in connection with, or relating in any manner to, the
Shares or the offering contemplated hereby, and which is included as part of or
referred to in any loss, claim, damage, liability or action arising out of or
based upon any matter covered by clause (i), (ii), (iii), (iv) or (v) above,
provided that the Company shall not be liable under this clause (vi) to the
extent that a court of competent jurisdiction shall have determined by a final
judgment that such loss, claim, damage, liability or action resulted directly
from any such acts or failures to act undertaken or omitted to be taken by such
Underwriter through its bad faith or willful misconduct; and to reimburse each
Underwriter and each such controlling person for any and all expenses (including
the fees and disbursements of counsel chosen by Robertson Stephens) as such
expenses are reasonably incurred by such Underwriter or such controlling person
in connection with investigating, defending, settling, compromising or paying
any such loss, claim, damage, liability, expense or action; provided, however,
that the foregoing indemnity agreement shall not apply to any loss, claim,
damage, liability or expense to the extent, but only to the extent, arising out
of or based upon any untrue statement or alleged untrue statement or omission or
alleged omission made in reliance upon and in conformity with written
information furnished to the Company by the Representatives expressly for use in
the Registration Statement, any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto); and provided, further, that with respect to
any preliminary prospectus, the foregoing indemnity agreement shall not inure to
the benefit of any Underwriter from whom the person asserting any loss, claim,
damage, liability or expense purchased Shares, or any person controlling such
Underwriter, if copies of the Prospectus were timely delivered to the
Underwriter pursuant to Section 2 and a copy of the Prospectus (as then amended
or supplemented if the Company shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of such Underwriter
to such person, if required by law so to have been delivered, at or prior to the
written confirmation of the sale of the Shares to such person, and if the
Prospectus (as so amended or supplemented) would have cured the defect giving
rise to such loss, claim,

                                       21
<PAGE>

damage, liability or expense. The indemnity agreement set forth in this Section
7(a) shall be in addition to any liabilities that the Company may otherwise
have.

     (b) Indemnification of the Company, its Directors and Officers . Each
Underwriter agrees, severally and not jointly, to indemnify and hold harmless
the Company, each of its directors, each of its officers who signed the
Registration Statement and each person, if any, who controls the Company within
the meaning of the Securities Act or the Exchange Act, against any loss, claim,
damage, liability or expense, as incurred, to which the Company, or any such
director, officer or controlling person may become subject, under the Securities
Act, the Exchange Act, or other federal or state statutory law or regulation, or
at common law or otherwise (including in settlement of any litigation, if such
settlement is effected with the written consent of such Underwriter), insofar as
such loss, claim, damage, liability or expense (or actions in respect thereof as
contemplated below) arises out of or is based upon any untrue or alleged untrue
statement of a material fact contained in the Registration Statement, any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto), or arises out of or is based upon 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, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in the Registration Statement, any preliminary
prospectus, the Prospectus (or any amendment or supplement thereto), in reliance
upon and in conformity with written information furnished to the Company by the
Representatives expressly for use therein; and to reimburse the Company, or any
such director, officer or controlling person for any legal and other expense
reasonably incurred by the Company, or any such director, officer or controlling
person in connection with investigating, defending, settling, compromising or
paying any such loss, claim, damage, liability, expense or action. The indemnity
agreement set forth in this Section 7(b) shall be in addition to any liabilities
that each Underwriter may otherwise have.

     (c) Information Provided by the Underwriters. The Company hereby
acknowledges that the only information that the Underwriters have furnished to
the Company expressly for use in the Registration Statement, the Preliminary
Prospectus or the Prospectus (or any amendment or supplement thereto) are the
statements set forth in the table in the first paragraph, the second, fourth and
twelfth paragraphs under the caption "Underwriting" in the Prospectus; and the
Underwriters confirm that such statements are correct.

     (d) Notifications and Other Indemnification Procedures . Promptly after
receipt by an indemnified party under this Section 7 of notice of the
commencement of any action, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party under this Section 7, notify
the indemnifying party in writing of the commencement thereof, but the omission
so to notify the indemnifying party will not relieve it from any liability which
it may have to any indemnified party for contribution or otherwise than under
the indemnity agreement contained in this Section 7 or to the extent it is not
prejudiced as a proximate result of such failure. In case any such action is
brought against any indemnified party and such indemnified party seeks or
intends to

                                       22
<PAGE>

seek indemnity from an indemnifying party, the indemnifying party will be
entitled to participate in, and, to the extent that it shall elect, jointly with
all other indemnifying parties similarly notified, by written notice delivered
to the indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof with counsel reasonably
satisfactory to such indemnified party; provided, however, if the defendants in
any such action include both the indemnified party and the indemnifying party
and the indemnified party shall have reasonably concluded that a conflict may
arise between the positions of the indemnifying party and the indemnified party
in conducting the defense of any such action or that there may be legal defenses
available to it and/or other indemnified parties which are different from or
additional to those available to the indemnifying party, the indemnified party
or parties shall have the right to select separate counsel to assume such legal
defenses and to otherwise participate in the defense of such action on behalf of
such indemnified party or parties. Upon receipt of notice from the indemnifying
party to such indemnified party of such indemnifying party's election so to
assume the defense of such action and approval by the indemnified party of
counsel, the indemnifying party will not be liable to such indemnified party
under this Section 7 for any legal or other expenses subsequently incurred by
such indemnified party in connection with the defense thereof unless (i) the
indemnified party shall have employed separate counsel in accordance with the
proviso to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (together with local counsel), approved by the indemnifying
party (Robertson Stephens in the case of Section 7(b) and Section 8),
representing the indemnified parties who are parties to such action), (ii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of commencement of the action, or (iii) the indemnifying party has
authorized the employment of counsel for the indemnified party at the expense of
the indemnifying party, in each of which cases the fees and expenses of counsel
shall be at the expense of the indemnifying party.

     (e) Settlements . The indemnifying party under this Section 7 shall not be
liable for any settlement of any proceeding effected without its written
consent, which consent shall not be unreasonably withheld, but if settled with
such consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party against any loss, claim, damage,
liability or expense by reason of such settlement or judgment. Notwithstanding
the foregoing sentence, if at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel as contemplated by Section 7(d) hereof, the indemnifying party agrees
that it shall be liable for any settlement of any proceeding effected without
its written consent if (i) such settlement is entered into more than 60 days
after receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement, compromise or consent to the entry of judgment in any pending or
threatened action, suit or proceeding in respect of which any indemnified party
is or could have been a party and indemnity was or could have been sought
hereunder by such indemnified party, unless

                                       23
<PAGE>

such settlement, compromise or consent includes (i) an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such action, suit or proceeding and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

     (f) Contribution . If the indemnification provided for in this Section 7 is
unavailable to or insufficient to hold harmless an indemnified party under
Section 7(a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) then each
indemnifying party shall contribute to the aggregate amount paid or payable by
such indemnified party in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the Underwriters
on the other from the offering of the Shares. If, however, the allocation
provided by the immediately preceding sentence is not permitted by applicable
law then each indemnifying party shall contribute to such amount paid or payable
by such indemnified party in such proportion as is appropriate to reflect not
only such relative benefits but also the relative fault of the Company on the
one hand and the Underwriters on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities, (or
actions or proceedings in respect thereof), as well as any other relevant
equitable considerations. The relative benefits received by the Company on the
one hand and the Underwriters on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) received by the Company bears to the total underwriting discounts and
commissions received by the Underwriters, in each case as set forth in the table
on the cover page of the Prospectus. The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company on the one hand or the
Underwriters on the other and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

    The Company and Underwriters agree that it would not be just and equitable
if contributions pursuant to this Section 7(f) were determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 7(f). The amount paid
or payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to above in
this Section 7(f) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (f), (i) no Underwriter shall be required to contribute any amount in
excess of the underwriting discounts and commissions applicable to the Shares
purchased by such Underwriter and (ii) no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations in this Section 7(f)
to contribute are several in proportion to their respective underwriting
obligations and not joint.

                                       24
<PAGE>

     (g) Timing of Any Payments of Indemnification . Any losses, claims,
damages, liabilities or expenses for which an indemnified party is entitled to
indemnification or contribution under this Section 7 shall be paid by the
indemnifying party to the indemnified party as such losses, claims, damages,
liabilities or expenses are incurred, but in all cases, no later than forty-five
(45) days of invoice to the indemnifying party.

     (h) Survival . The indemnity and contribution agreements contained in this
Section 7 and the representation and warranties of the Company set forth in this
Agreement shall remain operative and in full force and effect, regardless of (i)
any investigation made by or on behalf of any Underwriter or any person
controlling any Underwriter, the Company, its directors or officers or any
persons controlling the Company, (ii) acceptance of any Shares and payment
therefor hereunder, and (iii) any termination of this Agreement. A successor to
any Underwriter, or to the Company, its directors or officers, or any person
controlling the Company, shall be entitled to the benefits of the indemnity,
contribution and reimbursement agreements contained in this Section 7.

     (i) Acknowledgements of Parties . The parties to this Agreement hereby
acknowledge that they are sophisticated business persons who were represented by
counsel during the negotiations regarding the provisions hereof including,
without limitation, the provisions of this Section 7, and are fully informed
regarding said provisions. They further acknowledge that the provisions of this
Section 7 fairly allocate the risks in light of the ability of the parties to
investigate the Company and its business in order to assure that adequate
disclosure is made in the Registration Statement and Prospectus as required by
the Securities Act and the Exchange Act.

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

    SECTION 8. DEFAULT OF ONE OR MORE OF THE SEVERAL UNDERWRITERS. If, on the
First Closing Date or the Second Closing Date, as the case may be, any one or
more of

                                       25
<PAGE>

the several Underwriters shall fail or refuse to purchase Shares that it or they
have agreed to purchase hereunder on such date, and the aggregate number of
Common Shares which such defaulting Underwriter or Underwriters agreed but
failed or refused to purchase does not exceed 10% of the aggregate number of the
Shares to be purchased on such date, the other Underwriters shall be obligated,
severally, in the proportions that the number of Firm Shares set forth opposite
their respective names on Schedule A bears to the aggregate number of Firm
                          ----------
Shares set forth opposite the names of all such non-defaulting Underwriters, or
in such other proportions as may be specified by the Representatives with the
consent of the non-defaulting Underwriters, to purchase the Shares which such
defaulting Underwriter or Underwriters agreed but failed or refused to purchase
on such date. If, on the First Closing Date or the Second Closing Date, as the
case may be, any one or more of the Underwriters shall fail or refuse to
purchase Shares and the aggregate number of Shares with respect to which such
default occurs exceeds 10% of the aggregate number of Shares to be purchased on
such date, and arrangements satisfactory to the Representatives and the Company
for the purchase of such Shares are not made within 48 hours after such default,
this Agreement shall terminate without liability of any party to any other party
except that the provisions of Section 4, and Section 7 shall at all times be
effective and shall survive such termination. In any such case either the
Representatives or the Company shall have the right to postpone the First
Closing Date or the Second Closing Date, as the case may be, but in no event for
longer than seven days in order that the required changes, if any, to the
Registration Statement and the Prospectus or any other documents or arrangements
may be effected.

        As used in this Agreement, the term "Underwriter" shall be deemed to
include any person substituted for a defaulting Underwriter under this Section
8. Any action taken under this Section 8 shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

    SECTION 9. TERMINATION OF THIS AGREEMENT. Prior to the First Closing Date,
this Agreement may be terminated by the Representatives by notice given to the
Company if (a) at any time (i) trading or quotation in any of the Company's
securities shall have been suspended or limited by the Commission or by the
Nasdaq Stock Market, or trading in securities generally on either the Nasdaq
Stock Market or the New York Stock Exchange shall have been suspended or
limited, or minimum or maximum prices shall have been generally established on
any of such stock exchanges by the Commission or the National Association of
Securities Dealers, LLC; (ii) a general banking moratorium shall have been
declared by any of federal, New York, Delaware or California authorities; (iii)
there shall have occurred any outbreak or escalation of national or
international hostilities or any crisis or calamity, or any change in the United
States or international financial markets, or any substantial change or
development involving a prospective change in United States' or international
political, financial or economic conditions, as in the judgment of the
Representatives is material and adverse and makes it impracticable or
inadvisable to market the Common Shares in the manner and on the terms
contemplated in the Prospectus or to enforce contracts for the sale of
securities; (iv) in the judgment of the Representatives there shall have
occurred any Material Adverse Change; or (v) the Company shall have sustained a
loss by strike, fire, flood, earthquake, accident or other

                                       26
<PAGE>

calamity of such character as in the judgment of the Representatives may
interfere materially with the conduct of the business and operations of the
Company regardless of whether or not such loss shall have been insured or (b) in
the case of any of the events specified in 9(a)(i)-(v), such event singly or
together with any other event, makes it, in your judgment, impractical or
unadvisable to market the Common Shares in the manner and on the terms in the
Prospectus. Any termination pursuant to this Section 9 shall be without
liability on the part of (x) the Company to any Underwriter, except that the
Company shall be obligated to reimburse the expenses of the Representatives and
the Underwriters pursuant to Sections 5 and 6 hereof, (y) any Underwriter to the
Company, or (z) of any party hereto to any other party except that the
provisions of Section 7 shall at all times be effective and shall survive such
termination.

    SECTION 10. REPRESENTATIONS AND INDEMNITIES TO SURVIVE DELIVERY. The
respective indemnities, agreements, representations, warranties and other
statements of the Company, of its officers and of the several Underwriters set
forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation made by or on behalf of any Underwriter
or the Company or any of its or their partners, officers or directors or any
controlling person, as the case may be, and will survive delivery of and payment
for the Shares sold hereunder and any termination of this Agreement.

States of America located in the City of Boston or the courts of the

                                      120 Flanders Road

corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary

     NINTH.  1.  Actions, Suits and Proceedings Other than by or in the
                 ------------------------------------------------------
Right of the Corporation.  The Corporation shall indemnify each 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 (other than an action by or in the right of the Corporation), by
reason of the fact that he is or was, or has agreed to become, a director or
officer of the Corporation, or is or was serving, or has agreed to serve, at the
request of the Corporation, as a director, officer or trustee of, or in a
similar capacity with, another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan) (all such persons being
referred to hereafter as an "Indemnitee"), or by reason of any action alleged to
have been taken or omitted in such capacity, against all expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him or on his behalf in connection with such action, suit
or proceeding and any appeal therefrom, if he acted in good faith and in a
manner he 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 conduct was unlawful.  The termination of any
action, suit or proceeding by judgment, order, settlement, conviction or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
        ---- ----------
presumption that the person did not act in good faith and in a manner which he
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
reasonable cause to believe that his conduct was unlawful.  Notwithstanding
anything to the contrary in this Article, except as set forth in Section 7
below, the Corporation shall not indemnify an Indemnitee seeking indemnification
in connection with a proceeding (or part thereof) initiated by the Indemnitee
unless the initiation thereof was approved by the Board of Directors of the
Corporation.  Notwithstanding anything to the contrary in this Article, the
Corporation shall not indemnify an Indemnitee to the extent such Indemnitee is
reimbursed from the proceeds of insurance, and in the event the Corporation
makes any indemnification payments to an

                                       2
<PAGE>

Indemnitee and such Indemnitee is subsequently reimbursed from the proceeds of
insurance, such Indemnitee shall promptly refund such indemnification payments
to the Corporation to the extent of such insurance reimbursement.

     2.  Actions or Suits by or in the Right of the Corporation.  The
         -------------------------------------------------------
Corporation shall indemnify any Indemnitee who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason  of the fact that he is or was, or has agreed to become, a director or
officer of the Corporation, or is or was serving, or has agreed to serve, at the
request of the Corporation, as a director, officer or trustee of, or in a
similar capacity with, another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan), or by reason of any
action alleged to have been taken or omitted in such capacity, against all
expenses (including attorneys' fees) and, to the extent permitted by law,
amounts paid in settlement actually and reasonably incurred by him or on his
behalf in connection with such action, suit or proceeding and any appeal
therefrom, if he acted in good faith and in a manner he reasonably believed to
be in, or not opposed to, the best interests of the Corporation, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery of Delaware shall
determine upon application that, despite the adjudication of such liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses (including attorneys' fees)
which the Court of Chancery of Delaware shall deem proper.

     3.  Indemnification for Expenses of Successful Party.  Notwithstanding
         ------------------------------------------------
the other provisions of this Article, to the extent that an Indemnitee has been
successful, on the merits or otherwise, in defense of any action, suit or
proceeding referred to in Sections 1 and 2 of this Article, or in defense of any
claim, issue or matter therein, or on appeal from any such action, suit or
proceeding, he shall be indemnified against all expenses (including attorneys'
fees) actually and reasonably incurred by him or on his behalf in connection
therewith.  Without limiting the foregoing, if any action, suit or proceeding is
disposed of, on the merits or otherwise (including a disposition without
prejudice), without (i) the disposition being adverse to the Indemnitee, (ii) an
adjudication that the Indemnitee was liable to the Corporation, (iii) a plea of
guilty or nolo contendere by the Indemnitee, (iv) an adjudication that the
          ---- ----------
Indemnitee did not act in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Corporation, and (v) with
respect to any criminal proceeding, an adjudication that the Indemnitee had
reasonable cause to believe his conduct was unlawful, the Indemnitee shall be
considered for the purposes hereof to have been wholly successful with respect
thereto.

     4.  Notification and Defense of Claim.  As a condition precedent to his
         ---------------------------------
right to be indemnified, the Indemnitee must notify the Corporation in writing
as soon as practicable of any action, suit, proceeding or investigation
involving him for which indemnity will or could be sought. With respect to any
action, suit, proceeding or investigation of which the Corporation is so
notified, the Corporation will be entitled to participate therein at its own
expense and/or to assume the defense thereof at its own expense, with legal
counsel reasonably acceptable to the Indemnitee. After notice from the
Corporation to the Indemnitee of its election so to assume such defense, the
Corporation shall not be liable to the Indemnitee for any legal or other
expenses subsequently incurred by the Indemnitee in connection with such claim,
other than as

                                       3
<PAGE>

provided below in this Section 4. The Indemnitee shall have the right to employ
his own counsel in connection with such claim, but the fees and expenses of such
counsel incurred after notice from the Corporation of its assumption of the
defense thereof shall be at the expense of the Indemnitee unless (i) the
employment of counsel by the Indemnitee has been authorized by the Corporation,
(ii) counsel to the Indemnitee shall have reasonably concluded that there may be
a conflict of interest or position on any significant issue between the
Corporation and the Indemnitee in the conduct of the defense of such action or
(iii) the Corporation shall not in fact have employed counsel to assume the
defense of such action, in each of which cases the fees and expenses of counsel
for the Indemnitee shall be at the expense of the Corporation, except as
otherwise expressly provided by this Article. The Corporation shall not be
entitled, without the consent of the Indemnitee, to assume the defense of any
claim brought by or in the right of the Corporation or as to which counsel for
the Indemnitee shall have reasonably made the conclusion provided for in clause
(ii) above.

     5.  Advance of Expenses.  Subject to the provisions of Section 6
         -------------------
below, in the event that the Corporation does not assume the defense pursuant to
Section 4 of this Article of any action, suit, proceeding or investigation of
which the Corporation receives notice under this Article, any expenses
(including attorneys' fees) incurred by an Indemnitee in defending a civil or
criminal action, suit, proceeding or investigation or any appeal therefrom shall
be paid by the Corporation in advance of the final disposition of such matter;
provided, however, that the payment of such expenses incurred by an Indemnitee
- --------  -------
in advance of the final disposition of such matter shall be made only upon
receipt of an undertaking by or on behalf of the Indemnitee to repay all amounts
so advanced in the event that it shall ultimately be determined that the
Indemnitee is not entitled to be indemnified by the Corporation as authorized in
this Article.  Such undertaking shall be accepted without reference to the
financial ability of the Indemnitee to make such repayment.

     6.  Procedure for Indemnification.  In order to obtain indemnification
         -----------------------------
or advancement of expenses pursuant to Section 1, 2, 3, or 5 of this Article,
the Indemnitee shall submit to the Corporation a written request, including in
such request such documentation and information as is reasonably available to
the Indemnitee and is reasonably necessary to determine whether and to what
extent the Indemnitee is entitled to indemnification or advancement of expenses.
Any such indemnification or advancement of expenses shall be made promptly, and
in any event within 60 days after receipt by the Corporation of the written
request of the Indemnitee, unless with respect to requests under Section 1, 2 or
5 the Corporation determines within such 60-day period that the Indemnitee did
not meet the applicable standard of conduct set forth in Section 1 or 2, as the
case may be.  Such determination shall be made in each instance by (a) a
majority vote of the directors of the Corporation consisting of persons who are
not at that time parties to the action, suit or proceeding in question
("disinterested directors"), whether or not a quorum, (b) a majority vote of a
quorum of the outstanding shares of stock of all classes entitled to vote for
directors, voting as a single class, which quorum shall consist of stockholders
who are not at that time parties to the action, suit or proceeding in question,
(c) independent legal counsel (who may, to the extent permitted by law, be
regular legal counsel to the Corporation), or (d) a court of competent
jurisdiction.

     7.  Remedies.  The right to indemnification or advances as granted by
         --------
this Article shall be enforceable by the Indemnitee in any court of competent
jurisdiction if the Corporation

                                       4
<PAGE>

denies such request, in whole or in part, or if no disposition thereof is made
within the 60-day period referred to above in Section 6. Unless otherwise
required by law, the burden of proving that the Indemnitee is not entitled to
indemnification or advancement of expenses under this Article shall be on the
Corporation. Neither the failure of the Corporation to have made a determination
prior to the commencement of such action that indemnification is proper in the
circumstances because the Indemnitee has met the applicable standard of conduct,
nor an actual determination by the Corporation pursuant to Section 6 that the
Indemnitee has not met such applicable standard of conduct, shall be a defense
to the action or create a presumption that the Indemnitee has not met the
applicable standard of conduct. The Indemnitee's expenses (including attorneys'
fees) incurred in connection with successfully establishing his right to
indemnification, in whole or in part, in any such proceeding shall also be
indemnified by the Corporation.

     8.   Subsequent Amendment.  No amendment, termination or repeal of this
          --------------------
Article or of the relevant provisions of the General Corporation Law of Delaware
or any other applicable laws shall affect or diminish in any way the rights of
any Indemnitee to indemnification under the provisions hereof with respect to
any action, suit, proceeding or investigation arising out of or relating to any
actions, transactions or facts occurring prior to the final adoption of such
amendment, termination or repeal.

     9.   Other Rights.  The indemnification and advancement of expenses
          ------------
provided by this Article shall not be deemed exclusive of any other rights to
which an Indemnitee seeking indemnification or advancement of expenses may be
entitled under any law (common or statutory), agreement or vote of stockholders
or disinterested directors or otherwise, both as to action in his official
capacity and as to action in any other capacity while holding office for the
Corporation, and shall continue as to an Indemnitee who has ceased to be a
director or officer, and shall inure to the benefit of the estate, heirs,
executors and administrators of the Indemnitee.  Nothing contained in this
Article shall be deemed to prohibit, and the Corporation is specifically
authorized to enter into, agreements with officers and directors providing
indemnification rights and procedures different from those set forth in this
Article.  In addition, the Corporation may, to the extent authorized from time
to time by its Board of Directors, grant indemnification rights to other
employees or agents of the Corporation or other persons serving the Corporation
and such rights may be equivalent to, or greater or less than, those set forth
in this Article.

     10.  Partial Indemnification.  If an Indemnitee is entitled under any
          -----------------------
provision of this Article to indemnification by the Corporation for some or a
portion of the expenses (including attorneys' fees), judgments, fines or amounts
paid in settlement actually and reasonably incurred by him or on his behalf in
connection with any action, suit, proceeding or investigation and any appeal
therefrom but not, however, for the total amount thereof, the Corporation shall
nevertheless indemnify the Indemnitee for the portion of such expenses
(including attorneys' fees), judgments, fines or amounts paid in settlement to
which the Indemnitee is entitled.

     11.  Insurance.  The Corporation may purchase and maintain insurance,
          ---------
at its expense, to protect itself and any director, officer, employee or agent
of the Corporation or another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan) against any expense,
liability or loss incurred by him in any such capacity, or arising out of

                                       5
<PAGE>

his status as such, 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 Delaware.

     12.  Merger or Consolidation.  If the Corporation is merged into or
          -----------------------
consolidated with another corporation and the Corporation is not the surviving
corporation, the surviving corporation shall assume the obligations of the
Corporation under this Article with respect to any action, suit, proceeding or
investigation arising out of or relating to any actions, transactions or facts
occurring prior to the date of such merger or consolidation.

     13.  Savings Clause.  If this Article or any portion hereof shall be
          --------------
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each Indemnitee as to any expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with any action, suit, proceeding or investigation, whether civil,
criminal or administrative, including an action by or in the right of the
Corporation, to the fullest extent permitted by any applicable portion of this
Article that shall not have been invalidated and to the fullest extent permitted
by applicable law.

     14.  Definitions.  Terms used herein and defined in Section 145(h) and
          -----------
Section 145(i) of the General Corporation Law of Delaware shall have the
respective meanings assigned to such terms in such Section 145(h) and Section
145(i).

     15.  Subsequent Legislation.  If the General Corporation Law of
          ----------------------
Delaware is amended after adoption of this Article to expand further the
indemnification permitted to Indemnitees, then the Corporation shall indemnify
such persons to the fullest extent permitted by the General Corporation Law of
Delaware, as so amended.

     TENTH.  The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statue and this Certificate of
Incorporation, and all rights conferred upon stockholders herein are granted
subject to this reservation.

Preferred Stock of the Corporation are hereby designated "Series B Convertible
Preferred Stock" (the "Series B Preferred Stock"), each with the following
rights, preferences, powers, privileges and restrictions, qualifications and
limitations.

     1.   Dividends.
          ---------

     Dividends may be declared and paid on the Series A Preferred Stock and
Series B Preferred Stock from funds lawfully available therefor as and when
determined by the Board of Directors and subject to any preferential dividend
rights of any other class or series of then outstanding preferred stock.

     2.   Liquidation, Dissolution or Winding Up; Certain Mergers,
          --------------------------------------------------------
          Consolidations and Asset Sales.
          ------------------------------

          (a)  In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of shares of Series A
Preferred Stock and Series B Preferred Stock then outstanding shall be entitled
to be paid out of the assets of the Corporation available for distribution to
its stockholders, after and subject to the payment in full of all amounts
required to be distributed to the holders of any other class or series of stock
of the corporation ranking on liquidation prior and in preference to the Series
A Preferred Stock and Series B Preferred Stock (collectively referred to as
"Senior Preferred Stock"), but before any payment shall be made to the holders
of Common Stock or any other class or series of stock ranking on liquidation
junior to the Series A Preferred Stock and Series B Preferred Stock (such Common
Stock and other stock being collectively referred to as "Junior Stock") by
reason of their ownership thereof, an amount equal to $4.00 per share in the
case of the Series A Preferred Stock and $6.00 per share in the case of the
Series B Preferred Stock (in each case subject to appropriate adjustment in the
event of any stock dividend, stock split, combination or other similar
recapitalization affecting such shares of Series A Preferred Stock or Series B
Preferred Stock), plus declared but unpaid dividends.  If upon any such
liquidation, dissolution or winding up of the Corporation the remaining assets
of the Corporation available for distribution to its stockholders shall be
insufficient to pay the holders of shares of Series A Preferred Stock and Series
B Preferred stock the full amount to which they shall be entitled, the holders
of shares of Series A Preferred Stock and Series B Preferred Stock and any class
or series of stock ranking on liquidation on a parity with the Series A
Preferred Stock and Series B Preferred Stock shall share ratably in any
distribution of the remaining assets and funds of the Corporation in proportion
to the respective amounts which would otherwise be payable in respect of the
shares held by them upon such distribution if all amounts payable on or with
respect to such shares were paid in full.

                                       11
<PAGE>

          (b)  After the payment of all preferential amounts required to be paid
to the holders of Senior Preferred Stock, Series A Preferred Stock, Series B
Preferred Stock and any other class or series of stock of the Corporation
ranking on liquidation on a parity with the Series A Preferred stock and Series
B Preferred Stock, upon any voluntary or involuntary dissolution, liquidation or
winding up of the Corporation, the holders of shares of Common Stock, then
outstanding shall be entitled to receive the remaining assets and funds of the
Corporation available for distribution to its stockholders.

          (c)  A consolidation or merger of the Corporation with or into another
corporation or entity (where the Corporation is not the surviving entity and
where the stockholders of the Corporation do not hold a majority of the voting
securities of the surviving corporation), or a sale of all or substantially all
of the assets of the Corporation, shall be deemed a liquidation, dissolution or
winding up of the Corporation within the meaning of this Section 2; provided,
                                                                    --------
however, that each holder of Series A Preferred Stock and Series B Preferred
- -------
Stock shall have the right to elect the benefits of the provisions of Section
4(i) hereof in lieu of receiving payment in liquidation, dissolution or winding
up of the Corporation pursuant to this Section 2(c).

     3.   Voting.
          ------

          (a)  Each holder of outstanding shares of Series A Preferred Stock and
Series B Preferred Stock shall be entitled to the number of votes equal to the
number of whole shares of Common Stock into which the shares of Series A
Preferred Stock and Series B Preferred Stock held by such holder are then
convertible (as adjusted from time to time pursuant to Section 4 hereof), at
each meeting of stockholders of the Corporation (and written actions of
stockholders in lieu of meetings) with respect to any and all matters presented
to the stockholders of the Corporation for their action or consideration.
Except as provided by law, by the provisions of Subsection 3(b) or 3(c) below or
by the provisions establishing any other series of Preferred Stock, holders of
Series A Preferred Stock and Series B Preferred Stock and of any other
outstanding series of Series Preferred Stock shall vote together with the
holders of Common Stock as a single class.

          (b)  The holders of record of the shares of Series A Preferred Stock
and Series B Preferred Stock, exclusively and as a separate class, shall be
entitled to elect one director of the Corporation ("Series A and B Director"),
and the holders of record of the shares of Common Stock and of any other class
or series of voting stock (including the Series A Preferred Stock and Series B
Preferred Stock), exclusively and as a separate class, shall be entitled to
elect the balance of the total number of directors of the Corporation.  At any
meeting held for the purpose of electing directors, the presence in person or by
proxy of the holders of a majority of the shares of Series A Preferred Stock and
Series B Preferred Stock then outstanding shall constitute a quorum of the
Series A Preferred Stock and Series B Preferred Stock for the purpose of
electing the Series A and B Director by holders of the Series A Preferred Stock
and Series B Preferred Stock.  A vacancy in the Series A and B Director
directorship shall be filled only by vote or written consent in lieu of a
meeting of the holders of the Series A Preferred Stock and Series B Preferred
Stock.  The rights of the holders of the Series A Preferred Stock and Series B
Preferred Stock under this Subsection 3(b) shall terminate on the earlier of (i)
the date on which the outstanding shares of Series A Preferred Stock and Series
B Preferred Stock represent less than

                                       12
<PAGE>

5% of the outstanding shares of Common Stock, after giving effect to the
conversion into Common Stock of all outstanding shares of convertible Preferred
Stock, and (ii) the first anniversary of the closing of the sale by the
corporation of shares of Common Stock in a public offering, underwritten by a
nationally recognized underwriter, pursuant to an effective registration
statement under the Securities Act of 1933, as amended, in which the
Corporation, prior to giving effect to the proceeds of the Offering, is valued
at  least $135,000,000 (determined by multiplying the number of outstanding
shares of capital stock of the Corporation on a fully diluted basis by the
initial public offering price) and resulting in at least $15,000,000 of net
proceeds (determined by subtracting underwriters' discounts and commissions from
gross proceeds) to the Corporation.

          (c)  The Corporation shall not amend alter or repeal the preferences,
special rights or other powers of the Series A Preferred Stock or Series B
Preferred Stock so as to affect adversely the Series A Preferred Stock or Series
B Preferred Stock, without the written consent or affirmative vote of the
holders of a majority of the then outstanding shares of Series A Preferred Stock
or Series B Preferred Stock, respectively, given in writing or by vote at a
meeting, consenting or voting (as the case may be) separately as a class.  For
this purpose, without limiting the generality of the foregoing, the
authorization of any shares of capital stock with preference or priority over
the Series A Preferred Stock or Series B Preferred Stock as to redemption
rights, voting rights, the right to receive either dividends or amounts
distributable upon liquidation, dissolution or winding up of the Corporation, or
otherwise, shall be deemed to affect adversely the Series A Preferred Stock or
Series B Preferred Stock, and the authorization of any shares of capital stock
on a parity with Series A Preferred Stock or Series B Preferred Stock as to the
right to receive either dividends or amounts distributable upon liquidation,
dissolution or winding up of the Corporation shall not be deemed to affect
adversely the Series A Preferred Stock or Series B Preferred Stock,
respectively.  The number of authorized shares of Series A Preferred Stock and
Series B Preferred Stock may be increased or decreased (but not below the number
of shares then outstanding) by the directors of the corporation pursuant to
Section 151 of the General corporation Law of Delaware or by the affirmative
vote of the holders of a majority of the then outstanding shares of the Common
Stock, Series A Preferred Stock, Series B Preferred Stock and all other classes
or series of stock of the Corporation entitled to vote thereon, voting as a
single class, irrespective of the provisions of Section 242(b)(2) of the General
Corporation Law of Delaware.

     4.   Optional Conversion.  The holders of the Series A Preferred Stock and
          -------------------
Series B Preferred Stock shall have conversion rights as follows (the
"Conversion Rights"):

          (a)  Right to Convert.  Each share of Series A Preferred Stock and
              ----------------
Series B Preferred Stock shall be convertible, at the option of the holder
thereof, at any time and from time to time, and without the payment of
additional consideration by the holder thereof, into such number of fully paid
and nonassessable shares of Common Stock as is determined by dividing $4.00 by
the Conversion Price (as defined below) in effect at the time of conversion.
The Conversion Price, shall initially be $4.00.  Such initial Conversion Price,
and the rate at which shares of Series A Preferred Stock and Series B Preferred
Stock way be converted into shares of Common Stock, shall be subject to
adjustment as provided below.

                                       13
<PAGE>

     In the event of a notice of redemption of any shares of Series A Preferred
Stock or Series B Preferred Stock pursuant to Section 6 hereof, the Conversion
Rights of the shares of Series A Preferred Stock or Series B Preferred Stock,
respectively, designated for redemption shall terminate at the close of business
on the fifth full day preceding the date fixed for redemption, unless the
redemption price is not paid when due, in which case the Conversion Rights of
Series A Preferred Stock or Series B Preferred Stock for such shares shall
continue until such price is paid in full.  In the event of a liquidation of the
corporation, the Conversion Rights shall terminate at the close of business on
the first full day preceding the date fixed for the payment of any amounts
distributable on liquidation to the holders of Series A Preferred Stock or
Series B Preferred Stock, respectively.

          (b)  Fractional Shares.  No fractional shares of Common Stock shall be
               -----------------
issued upon conversion of the Series A Preferred Stock or Series B Preferred
Stock, in lieu of any fractional shares to which the holder would otherwise be
entitled, the Corporation shall pay cash equal to such fraction multiplied by
the then effective Conversion Price.

          (c)  Mechanics of Conversion.
               -----------------------

               (i)  In order for a holder of Series A Preferred Stock or Series
B Preferred Stock to convert shares of Series A Preferred Stock or Series B
Preferred Stock into shares of Common Stock, such holder shall surrender the
certificate or certificates for such shares of Series A Preferred Stock or
Series B Preferred Stock, at the office of the transfer agent for the Series A
Preferred Stock or Series B Preferred Stock, respectively (or at the principal
office of the Corporation if the corporation serves as its own transfer agent),
together with written notice that such holder elects to convert all or any
number of the shares of the Series A Preferred Stock or Series B Preferred stock
represented by such certificate or certificates. Such notice shall state such
holder's name or the names of the nominees in which such holder wishes the
certificate or certificates for shares of Common Stock to be issued. If required
by the Corporation, certificates surrendered for conversion shall be endorsed or
accompanied by a written instrument or instruments of transfer, in form
satisfactory to the Corporation, duly executed by the registered holder or his
or its attorney duly authorized in writing. The date of receipt of such
certificates and notice by the transfer agent (or by the Corporation if the
Corporation serves as its own transfer agent) shall be the conversion date
("Conversion Date") and such holder shall be treated as a record holder of
Common Stock on such date. The Corporation shall, as soon as practicable after
the Conversion Date, issue and deliver at such office to such holder of Series A
Preferred Stock or Series B Preferred Stock, or to his or its nominees, a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled, together with cash in lieu of any fraction of a
share, and a certificate or certificates for the number of shares of Series A
Preferred Stock or Series B Preferred Stock represented by the surrendered
certificate but not converted.

               (ii) The Corporation shall at all times when the Series A
Preferred Stock or Series B Preferred Stock shall be outstanding, reserve and
keep available out of its authorized but unissued stock, for the purpose of
effecting the conversion of the Series A Preferred Stock or Series B Preferred
Stock, such number of its duly authorized shares of Common Stock as shall from
time to time be sufficient to effect the conversion of all outstanding Series A
Preferred Stock or Series B Preferred Stock. Before taking any action which
would

                                       14
<PAGE>

cause an adjustment reducing the Conversion Price below the then par value of
the shares of Common Stock issuable upon conversion of the Series A Preferred
Stock or Series B Preferred Stock, the Corporation will take any corporate
action which may, in the opinion of its counsel, be necessary in order that the
Corporation may validly and legally issue fully paid and nonassessable shares of
Common Stock at such adjusted Conversion Price.

               (iii) Upon any such conversion, adjustment to the Conversion
Price of Series A Preferred Stock or Series B Preferred Stock, shall be made for
any declared but unpaid dividends on the Series A Preferred Stock or Series B
Preferred Stock, respectively, surrendered for conversion or on the Common Stock
delivered upon conversion.

               (iv)  All shares of Series A Preferred Stock and Series B
Preferred Stock which shall have been surrendered for conversion as herein
provided shall no longer be deemed to be outstanding and all rights with respect
to such shares, including the rights, if any, to receive notices and to vote,
shall immediately cease and terminate on the Conversion Date, except only the
right of the holders thereof to receive shares of Common Stock in exchange
therefor and payment of any dividends declared but unpaid thereon. Any shares of
Series A Preferred Stock or Series B Preferred Stock so converted shall be
retired and cancelled and shall not be reissued, and the Corporation (without
the need for stockholder action) may from time to time take such appropriate
action as may be necessary to reduce the authorized Series A Preferred Stock and
Series B Preferred Stock accordingly.

               (v)   The Corporation shall pay any and all issue and other taxes
that may be payable in respect of any issuance or delivery of shares of Common
Stock upon conversion of shares of Series A Preferred Stock or Series B
Preferred Stock pursuant to this Section 4. The Corporation shall not, however,
be required to pay any tax which may be payable in respect of any transfer
involved in the issuance and delivery of shares of Common Stock in a name other
than that in which the shares of Series A Preferred Stock or Series B Preferred
Stock so converted were registered, and, to the extent the Company would be
required to pay such a tax, no such issuance or delivery shall be made unless
and until the person or entity requesting such issuance has paid to the
Corporation the amount of any such tax or has established, to the satisfaction
of the Corporation, that such tax has been paid.

          (d)  Adjustments to Conversion Price for Diluting Issues:
               ---------------------------------------------------

               (i)   Special Definitions.  For purposes of this Subsection 4(d),
                     -------------------
the following definitions shall apply:

                     (A)  "Option" shall mean rights, options or warrants to
                           ------

                     (B)  "Original Issue Date" shall mean the date on which a
                           -------------------

                               exercise of any Options outstanding on the

                         (II)  as a dividend or distribution on Series A
                               Preferred Stock or Series B Preferred Stock;

                         (III) by reason of a dividend, stock split, split-up
                               or other distribution on shares of Common Stock
                               that is covered by Subsection 4(e) or 4(f) below;
                               or

                         (IV)  to employees, officers or directors of, or
                               consultants or advisors to, the Corporation
                               pursuant to a plan adopted by the Board of
                               Directors of the Corporation (which, together
                               with all other such plans, provides for the
                               issuance of no more than an aggregate of
                               1,500,000 shares of Common Stock (subject to
                               appropriate adjustment in the event of any stock
                               dividend, stock split, combination or other
                               similar recapitalization affecting the Common
                               Stock).

          (ii) No Adjustment of Conversion Price.  No adjustment in the number
               ---------------------------------
of shares of Common Stock into which the Series A Preferred Stock or Series B
Preferred Stock is convertible shall be made, by adjustment in the applicable
Conversion Price thereof, unless the consideration per share (determined
pursuant to subsection 4(d)(v)) for an Additional Share of Common Stock issued
or deemed to be issued by the Corporation is less than the applicable Conversion
Price in effect on the date of, and immediately prior to, the issue of such
Additional Shares.

          (iii)  Issue of Securities Deemed Issue of Additional Shares of
                 --------------------------------------------------------
                 Common Stock.
                 ------------

     If the Corporation at any time or from time to time after the Original
Issue Date shall issue any Options or Convertible Securities or shall fix a
record date for the determination of holders of any class of securities entitled
to receive any such Options or Convertible Securities, then the maximum number
of shares of Common Stock (as set forth in the instrument relating thereto
without regard to any provision contained therein for a subsequent adjustment of
such number) issuable upon the exercise of such options or, in the case of
Convertible Securities and Options therefor, the conversion or exchange of such
Convertible Securities, shall be deemed to be Additional Shares of Common Stock
issued as of the time of such issue or, in case such a

                                       16
<PAGE>

record date shall have been fixed, as of the close of business on such record
date, provided that Additional Shares of Common Stock shall not be deemed to
have been issued unless the consideration per share (determined pursuant to
Subsection 4(d)(v) hereof) of such Additional Shares of Common Stock would be
less than the applicable Conversion Price in effect on the date of and
immediately prior to such issue, or such record date, as the case may be, and
provided further that in any such case in which Additional Shares of Common
Stock are deemed to be issued:

                    (A)  No further adjustment in the Conversion Price shall be
made upon the subsequent issue of Convertible Securities or shares of Common
Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                    (B)  If such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase in the
consideration payable to the Corporation, upon the exercise, conversion or
exchange thereof, the Conversion Price computed upon the original issue thereof
(or upon the occurrence of a record date with respect thereto), and any
subsequent adjustments based thereon, shall, upon any such increase becoming
effective, be recomputed to reflect such increase insofar as it affects such
options or the rights of conversion or exchange under such Convertible
Securities;

                    (C)  Upon the expiration or termination of any unexercised
option, the Conversion Price shall be readjusted, and the Additional Shares of
Common Stock deemed issued as the result of the original issue of such option
shall not be deemed issued for the purposes of any subsequent adjustment of the
Conversion Price;

                    (D)  In the event of any change in the number of shares of
Common Stock issuable upon the exercise, conversion or exchange of any Option or
Convertible Security, including, but not limited to, a change resulting from the
anti-dilution provisions thereof, the Conversion Price then in effect shall
forthwith be readjusted to such Conversion Price as would have obtained had the
adjustment which was made upon the issuance of such Option or Convertible
Security prior to such change been made upon the basis of such change; and

                    (E)  No readjustment pursuant to clause (B), (C) or (D)
above shall have the effect of increasing the Conversion Price to an amount
which exceeds the lower of W the Conversion Price on the original adjustment
date, or (ii) the Conversion Price that would have resulted from any issuances
of Additional Shares of Common Stock between the original adjustment date and
such readjustment date.

     In the event the Corporation, after the Original Issue Date, amends the
terms of any Options or Convertible Securities (whether such options or
Convertible Securities were outstanding on the Original Issue Date or were
issued after the Original Issue Date), then such options or Convertible
Securities, as so amended, shall be deemed to have been issued after the
Original Issue Date and the provisions of this Subsection 4(d)(iii) shall apply.

               (iv) Adjustment of Conversion Price Upon Issuance of Additional
                    ----------------------------------------------------------
                    Shares of Common Stock.
                    ----------------------

                                       17
<PAGE>

     In the event the Corporation shall at any time after the Original Issue
Date issue Additional Shares of Common Stock (including Additional Shares of
Common Stock deemed to be issued pursuant to Subsection 4(d)(iii), but excluding
shares issued as a stock split or combination as provided in Subsection 4(e) or
upon a dividend or distribution as provided in Subsection 4(f)), without
consideration or for a consideration per share less than the applicable
Conversion Price in effect on the date of and immediately prior to such
issuance, then and in such event, such Conversion Price shall be reduced,
concurrently with such issue, to a price (calculated to the nearest cent)
determined by multiplying such Conversion Price by a fraction, (A) the numerator
of which shall be (1) the number of shares of Common Stock outstanding
immediately prior to such issue plus (2) the number of shares of Common Stock
which the aggregate consideration received or to be received by the Corporation
for the total number of Additional Shares of Common Stock so issued would
purchase at such Conversion Price; and (B) the denominator of which shall be the
number of shares of Common Stock outstanding immediately prior to such issue
plus the number of such Additional Shares of Common Stock so issued; provided
                                                                     --------
that, (i) for the purpose of this Subsection 4(d)(iv), all shares of Common
- ----
Stock issuable upon exercise or conversion of Options (including the conversion
into Common Stock of Convertible Securities issuable upon the exercise of such
Options) or Convertible Securities outstanding immediately prior to such issue
shall be deemed to be outstanding, (ii) the number of shares of Common Stock
deemed issuable upon exercise or conversion of such outstanding Options and
convertible Securities shall not give effect to any adjustments to the
conversion price or conversion rate of such Options or Convertible Securities
resulting from the issuance of Additional Shares of Common Stock that is the
subject of this calculation, and (iii) immediately after any Additional Shares
of Common Stock are deemed issued pursuant to Section 4(d)(iii), such Additional
Shares of Common Stock shall be deemed to be outstanding.

               (v)  Determination of Consideration.  For purposes of this
                    ------------------------------
Subsection 4(d), the consideration received by the Corporation for the issue of
any Additional Shares of Common Stock shall be computed as follows:

                    (A)  Cash and Property:  Such consideration shall:
                         -----------------

                         (I)   insofar as it consists of cash, be computed at
the aggregate amount of cash received by the corporation, excluding amounts paid
or payable for accrued interest or accrued dividends;

                         (II)  insofar as it consists of property other than
cash, be computed at the fair market value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and

                         (III) in the event Additional Shares of Common Stock
are issued together with other shares or securities or other assets of the
Corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (I) and (II) above,
as determined in good faith by the Board of Directors.

                    (B)   Options and Convertible Securities.  The consideration
                          ----------------------------------
per share received by the Corporation for Additional Shares of Common Stock
deemed to have been

                                       18
<PAGE>

issued pursuant to Subsection 4(d)(iii), relating to Options and Convertible
Securities, shall be determined by dividing

                    (x)  the total amount, if any, received or receivable by the
Corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration) payable to
the Corporation upon the exercise of such Options or the conversion or exchange
of such Convertible Securities, or in the case of options for Convertible
Securities, the exercise of such Options for Convertible securities and the
conversion or exchange of such Convertible Securities, by

                    (y)  the maximum number of shares of Common Stock (as set
forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

          (vi) Multiple Closing Dates.  In the event the Corporation shall issue
               ----------------------
on more than one date Additional Shares of Common Stock which are comprised of
shares of the same series or class of Preferred Stock, and such issuance dates
occur within a period of no more than 120 days, then the Conversion Price shall
be adjusted only once on account of such issuances, with such adjustment to
occur upon the final such issuance and to give effect to all such issuances as
if they occurred on the date of the final such issuance.

     (e)  Adjustment for Stock Splits and Combination.  If the Corporation
          -------------------------------------------
shall at any time or from time to time after the Original Issue Date effect a
subdivision of the outstanding Common Stock into a greater number of shares of
Common Stock (by reclassification or otherwise than by payment of a dividend in
Common Stock), the Conversion Price then in effect immediately before that
subdivision shall be proportionately decreased.  If the Corporation shall at any
time or from time to time after the Original Issue Date combine the outstanding
shares of Common Stock into a lesser number of shares of Common Stock, the
Conversion Price then in effect immediately before the combination shall be
proportionately increased.  Any adjustment under this paragraph shall become
effective at the close of business on the date the subdivision or combination
becomes effective.

     (f)  Adjustment for Certain Dividends and Distributions.  In the event
          --------------------------------------------------
the Corporation at any time, or from time to time after the Original Issue Date
shall make or issue, or fix 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, then and in each such event the Conversion
Price for the Series A Preferred Stock and Series B Preferred stock then in
effect shall be decreased as of the time of such issuance or, in the event such
a record date shall have been fixed, as of the close of business on such record
date, by multiplying the Conversion Price for the Series A Preferred Stock or
Series B Preferred Stock, as applicable, then in effect by a fraction:

                                       19
<PAGE>

               (1)  the numerator of which shall be 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

               (2)  the denominator of which shall be 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, if such record date shall have been fixed and such dividend
is not fully paid or if such distribution is not fully made on the date fixed
therefor, the Conversion Price for the Series A Preferred Stock and Series B
Preferred Stock shall be recomputed accordingly as of the close of business on
such record date and thereafter the Conversion Price for the Series A Preferred
Stock and Series B Preferred Stock shall be adjusted pursuant to this paragraph
as of the time of actual payment of such dividends or distributions; and
provided further, however, that no such adjustment shall be made to Series A
Preferred Stock or Series B Preferred Stock if the holders of Series A Preferred
Stock or Series B Preferred Stock, respectively, simultaneously receive a
dividend or other distribution of shares of Common Stock in a number equal to
the number of shares of Common Stock as they would have received it all
outstanding shares of Series A Preferred Stock or Series B Preferred Stock,
respectively, had been converted into Common Stock on the date of such event.

          (g)  Adjustments for other Dividends and Distributions.  In the event
               -------------------------------------------------
the Corporation at any time or from time to time after the Original Issue Date
for the Series A Preferred Stock or Series B Preferred Stock shall make or
issue, or fix a record date for the determination of holders of Common Stock
entitled to receive, a dividend or other distribution payable in securities of
the Corporation other than shares of Common Stock, then and in each such event
provision shall be made so that the holders of the Series A Preferred Stock or
Series B Preferred Stock, respectively, shall receive upon conversion thereof in
addition to the number of shares of Common Stock receivable thereupon, the
amount of securities of the Corporation that they would have received had the
Series A Preferred Stock or Series B Preferred Stock, respectively, 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, giving application to all adjustments called for during such period
under this paragraph with respect to the rights of the holders of the Series A
Preferred Stock or Series B Preferred Stock; and provided further, however, that
no such adjustment to the Series A Preferred Stock or Series B Preferred Stock
shall be made if the holders of Series A Preferred Stock or Series B Preferred
Stock, respectively, simultaneously receive a dividend or other distribution of
such securities in an amount equal to the amount of such securities as they
would have received if all outstanding shares of Series A Preferred Stock or
Series B Preferred Stock, respectively, had been converted into Common Stock on
the date of such event.

          (h)  Adjustment for Reclassification, Exchange, or Substitution.  If
              ----------------------------------------------------------
the Common Stock issuable upon the conversion of the Series A Preferred Stock or
Series B Preferred Stock shall be changed into the same or a different number of
shares of any class or classes of stock, whether by capital reorganization,
reclassification, or otherwise (other than a

                                       20
<PAGE>

subdivision or combination of shares or stock dividend provided for above, or a
reorganization, merger, consolidation, or sale of assets provided for below),
then and in each such event the holder of each such share of Series A Preferred
Stock or series B Preferred Stock, respectively, shall have the right thereafter
to convert such share into the kind and amount of shares of stock and other
securities and property receivable upon such reorganization. reclassification,
or other change, by holders of the number of shares of Common Stock into which
such shares of Series A ' Preferred Stock or Series B Preferred Stock,
respectively, might have been converted immediately prior to such
reorganization, reclassification, or change, all subject to further adjustment
as provided herein.

          (i)  Adjustment for merger or-Reorganization, etc.  In case of any
               --------------------------------------------
consolidation or merger of the Corporation with or into another corporation or
the sale or transfer of all or substantially all of the assets of the
Corporation to another corporation, each share of Series A Preferred Stock and
Series B Preferred Stock shall thereafter be convertible into the kind and
amount of shares of stock or other securities or property to which a holder of
the number of shares of Common Stock of the Corporation deliverable upon
conversion of such Series A Preferred Stock and Series B Preferred Stock,
respectively, would have been entitled upon such consolidation, merger, sale or
transfer; and, in such case, appropriate adjustment (as determined in good faith
by the Board of Directors) shall be made in the application of the provisions in
this Section 4 set forth with respect to the rights and interest thereafter of
the holders of the Series A Preferred Stock or Series B Preferred Stock, to the
end that the provisions set forth in this Section 4 (including provisions with
respect to changes in and other adjustments of the Conversion Price) shall
thereafter be applicable, as nearly as reasonably may be, in relation to any
shares of stock or other property thereafter deliverable upon the conversion of
the Series A Preferred Stock or Series B Preferred Stock, respectively.  Each
holder of Series A Preferred Stock or Series B Preferred Stock, upon the
occurrence of a merger or consolidation of the Corporation into or with another
corporation (where the Corporation is not the surviving entity and where the
stockholders of the Corporation fail to hold a majority of the voting securities
of the surviving corporation) or the sale or all or substantially all of the
assets of the Corporation, shall have the option of electing treatment of his
shares of Series A Preferred Stock and Series B Preferred Stock under either
this Section 4(i) or Section 2(c) hereof.

          (j)  No Impairment.  The Corporation will not, by amendment of its
               -------------
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation, but will at
all times in good faith assist in the carrying out of all the provisions of this
Section 4 and in the taking of all such action as my be necessary or appropriate
in order to protect the Conversion Rights of the holders of the Series A
Preferred Stock and Series B Preferred Stock against impairment.

          (k)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Conversion Price pursuant to this Section 4,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with  the terms hereof and furnish to each holder of
Series A Preferred Stock and Series B Preferred Stock a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based.  The Corporation shall, upon the
written request at any time

or cause to be furnished to such holder a similar certificate setting forth W
such adjustments and readjustments, (ii) the Conversion Price then in effect,
and (iii) the number of shares of Common Stock and the amount, if any, of other
property which then would be received upon the conversion of Series A Preferred
Stock or Series B Preferred Stock.

                     shares of Common Stock;

               (iv)  of any reclassification of the Common Stock of the
                     Corporation (other than a subdivision or combination of its
                     outstanding shares of Common Stock or a stock dividend or
                     stock distribution thereon), or of any consolidation or
                     merger of the Corporation into or with another corporation,
                     or of the sale of all or substantially all of the assets of

     5.   Mandatory Conversion.
          -----------------------

          (a)  Upon the closing of the sale of shares of Common Stock in a
public offering, underwritten by a nationally recognized underwriter, pursuant
to an effective registration statement under the Securities Act of 1933, as
amended, in which the Corporation, prior to giving effect to the proceeds of the
Offering, is valued at least $135,000,000 (determined by multiplying the number
of outstanding shares of capital stock of the Corporation on a fully diluted
basis by the initial public offering price) and resulting in at least
$15,000,000 of net proceeds (determined by subtracting underwriters, discounts
and commissions from gross proceeds) to the Corporation (the "Mandatory
Conversion Date"), (i) all outstanding shares of Series A Preferred Stock and
Series B Preferred Stock shall automatically be converted into shares of Common
Stock, at the then effective conversion rate and (ii) the number of authorized
shares of Preferred Stock shall be automatically reduced by the number of shares
of Preferred Stock that had been designated as Series A Preferred Stock and
Series B Preferred Stock, and all provisions included under the caption "Series
A Convertible Preferred Stock" and Series B Preferred Stock and all references
to the' Series A Preferred Stock, shall be deleted and shall be of no further
force or effect.

          (b)  All holders of record of shares of series A Preferred Stock or
Series B Preferred Stock shall be given written notice of the Mandatory
Conversion Date and the place designated for mandatory conversion of all such
shares of Series A Preferred Stock or Series B Preferred Stock, respectively,
pursuant to this Section 5.  Such notice need not be given in advance of the
occurrence of the Mandatory Conversion Date.  All holders of record of shares of
Series A Preferred Stock and Series B Preferred Stock shall be given written
notice of the filing by the Corporation of a registration statement under the
Securities Act of 1933, as amended, in connection with which the Corporation is
proposing to undertake a public offering, the closing date of which would be the
"Mandatory Conversion Date" as defined in paragraph (a) above.  Such notice
shall be given within ten days following the filing of such registration
statement.  Any notice required pursuant to this paragraph (b) shall be sent by
first class or registered mail, postage prepaid, to each record holder of Series
A Preferred Stock or Series B Preferred Stock at such holder's address last
shown on the records of the transfer agent for the Series A Preferred Stock or
Series B Preferred Stock (or the records of the Corporation, if it serves as its
own transfer agent).  Upon receipt of such notice, each holder of shares of
Series A Preferred Stock or Series B Preferred Stock shall surrender his or its
certificate or certificates for all such shares to the Corporation at the place
designated in such notice, and shall thereafter receive certificates for the
number of shares of Common Stock to which such holder is entitled pursuant to
this Section 5.  On the Mandatory Conversion Date, all rights with respect to
the Series A Preferred Stock and Series B Preferred Stock so converted,
including the rights, if any, to receive notices and vote (other than as a
holder of Common Stock) will terminate, except only the rights of the holders
thereof, upon surrender of their certificate or certificates therefor, to
receive certificates for the number of shares of Common Stock into which such
Series A Preferred Stock and Series B Preferred Stock has been converted, and
payment of any declared but unpaid dividends thereon.  If so required by the
Corporation, certificates surrendered for conversion shall be endorsed or
accompanied by written instrument or instruments of transfer, in form
satisfactory to

                                       23
<PAGE>

the corporation, duly executed by the registered holder or by his or its
attorney duly authorized in writing. As soon as practicable after the Mandatory
Conversion Date and the surrender of the certificate or certificates for Series
A Preferred Stock or Series B Preferred Stock, the Corporation shall cause to be
issued and delivered to such holder, or on his or its written order, a
certificate or certificates for the number of full shares of Common Stock
issuable on such conversion in accordance with the provisions hereof and cash as
provided in Subsection 4(b) in respect of any fraction of a share of Common
Stock otherwise issuable upon such conversion.

          (c)  All certificates evidencing shares of Series A Preferred Stock
and Series B Preferred Stock which are required to be surrendered for conversion
in accordance with the provisions hereof shall, from and after the Mandatory
Conversion Date, be deemed to have been retired and cancelled and the shares of
Series A Preferred Stock and Series B Preferred Stock represented thereby
converted into Common Stock for all purposes, notwithstanding the failure of the
holder or holders thereof to surrender such certificates on or prior to such
date. The Corporation may thereafter take such appropriate action (without the
need for stockholder action) as may be necessary to reduce the authorized Series
A Preferred Stock and Series B Preferred Stock accordingly.

     6.   Mandatory Redemption.
          -----------------------

          (a)  The Corporation will, subject to the conditions set forth in

stock held by such holder for which Corporation received cash in payment for the
issuance and sale thereof, on the applicable Mandatory Redemption Date:

Redemption Date are insufficient to redeem the number of shares of Series A
Preferred Stock and Series B Preferred Stock required under this Section 6 to be
redeemed on such date, those funds which are legally available will be used to
redeem the maximum possible number of such shares of Series A Preferred Stock
and Series B Preferred Stock ratably on the basis of the number of shares of
Series A Preferred Stock and Series B Preferred Stock which would be redeemed on
such date if the funds of the Corporation legally available therefor had been
sufficient to redeem all shares of Series A Preferred Stock and Series B
Preferred Stock required to be redeemed on such date.  At any time thereafter
when additional funds of the Corporation become legally available for the
redemption of Series A Preferred Stock and Series B Preferred Stock, such funds
will be used, at the end of the next succeeding fiscal quarter, to redeem the
balance of the shares which the Corporation was theretofore obligated to redeem,
or such portion thereof for which funds are available, ratably on the basis set
forth in the preceding sentence.

          (c)  The holder of Series A Preferred Stock or Series B Preferred
Stock requesting redemption shall provide notice of any redemption of Series A
Preferred Stock or Series B Preferred Stock pursuant to this Section 6, by
registered mail, postage prepaid, to the Corporation not less than six (6)
months prior to the date on which such redemption is to be made. The notice will
specify the number of shares which are to be redeemed. Upon receipt of any such
notice of redemption, the Corporation will become obligated to redeem on the
applicable Mandatory Redemption Date all Series A Preferred Stock and Series B
Preferred Stock specified therein (other than such shares of Series A Preferred
Stock and Series B Preferred Stock as are duly converted pursuant to Section 4
prior to the close of business on the fifth full day preceding the Mandatory
Redemption Date). In case less than all Series A Preferred Stock or Series B
Preferred Stock represented by any certificate is redeemed in any redemption
pursuant to this Section 6, a new certificate will be issued representing the
unredeemed Series A Preferred Stock or Series B Preferred Stock without cost to
the holder thereof.

          (d)  Unless there shall have been a default in payment of the
Mandatory Redemption Price, no share of Series A Preferred Stock that is
redeemed shall be entitled to any dividends declared after its Mandatory
Redemption Date, and on such Mandatory Redemption Date all rights of the holder
of such share as a stockholder of the Corporation by reason of the ownership of
such share will cease, except the right to receive the Mandatory Redemption
Price of such share, without interest, upon presentation and surrender of the
certificate representing such share, and such share will not from and after such
Mandatory Redemption Date be deemed to be outstanding.

                                       25

          (e)  Any Series A Preferred Stock or Series B Preferred Stock redeemed
pursuant to this Section 6 will be cancelled and will not under any
circumstances be reissued, sold or transferred and the Corporation may from time
to time take such appropriate action as may be necessary to reduce the
authorized Series A Preferred Stock and Series B Preferred Stock accordingly.

     IN WITNESS WHEREOF, the Corporation has caused its corporate seal to be
affixed hereto and this Certificate of Amendment to be signed by its President
this 1/st/ day of November, 1996.

          (a)  In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of shares of Series A
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock then
outstanding shall be entitled to be paid out of the assets of the Corporation
available for distribution to its stockholders, after and subject to the payment
in full of all amounts required to be distributed to the holders of any other
class or series of stock of the Corporation ranking on liquidation prior and in
preference to the Series A Preferred Stock, Series B Preferred Stock and Series
C Preferred Stock (collectively referred to as "Senior Preferred Stock"), but
before any payment shall be made to the holders of Common Stock or any other
class or series of stock ranking on liquidation junior to the Series A Preferred

their ownership thereof, an amount equal to $4.00 per share in the case of the

adjustment in the event of any stock dividend, stock split, combination or other
similar recapitalization affecting such shares of Series A Preferred Stock,

Corporation the remaining assets of the Corporation available for distribution

full amount to which they shall be entitled, the holders of shares of Series A

to the holders of Senior Preferred Stock, Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and any other class or series of stock
of the Corporation ranking on liquidation on a parity with the Series A
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock, upon any
voluntary or involuntary dissolution, liquidation or winding up of the
Corporation, the holders of shares of Common Stock then outstanding shall be
entitled to receive the remaining assets and funds of the Corporation available
for distribution to its stockholders.

          (c)  A consolidation or merger of the Corporation with or into another
corporation or entity (where the Corporation is not the surviving entity and
where the stockholders of the Corporation do not hold a majority of the voting
securities of the surviving corporation), or a sale of all or substantially all
of the assets of the Corporation, shall be deemed a liquidation, dissolution or
winding up of the Corporation within the meaning of this Section 2; provided,
                                                                    --------

          (a)  Each holder of outstanding shares of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock shall be entitled to the
number of votes equal to the number of whole shares of Common Stock into which
the shares of Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock held by such holder are then convertible (as adjusted from time
to time pursuant to Section 4 hereof), at each meeting of stockholders of the
Corporation (and written actions of stockholders in lieu of meetings) with
respect to any and all matters presented to the stockholders of the Corporation
for their action or consideration. Except as provided by law, by the provisions
of Subsection 3(b) or 3(c) below or by the provisions establishing any other
series of Preferred Stock, holders of Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock and of any other outstanding series
of Series Preferred Stock, shall vote together with the holders of Common Stock
as a single class.

          (b)  (1)  The holders of record of the shares of Series A Preferred
Stock and Series B Preferred Stock, exclusively and as a separate class, shall
be entitled to elect one director of the Corporation ("Series A and B
Director"), and, except as set forth in (2) below, the holders of record of the
shares of Common Stock and of any other class or series of voting stock
(including the Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock), exclusively and as a separate class, shall be entitled to
elect the balance of the total number of directors of the Corporation. At any
meeting held for the purpose of electing directors, the presence in person or by
proxy of the holders of a majority of the shares of Series A Preferred

                                       30
<PAGE>

Stock and Series B Preferred Stock then outstanding shall constitute a quorum of
the Series A Preferred Stock and Series B Preferred Stock for the purpose of
electing the Series A and B Director by holders of the Series A Preferred Stock
and Series B Preferred Stock. A vacancy in the Series A and B Director
directorship shall be filled only by vote or written consent in lieu of a
meeting of the holders of the Series A Preferred Stock and Series B Preferred
Stock. The rights of the holders of the Series A Preferred Stock and Series B
Preferred Stock under this Subsection 3(b)(1) shall terminate on the earlier of
(i) the date on which the outstanding shares of Series A Preferred Stock and
Series B Preferred Stock represent less than 5% of the outstanding shares of
Common Stock, after giving effect to the conversion into Common Stock of all
outstanding shares of convertible Preferred Stock, and (ii) the first
anniversary of the closing of the sale by the Corporation of shares of Common
Stock in a public offering, underwritten by a nationally recognized underwriter,
pursuant to an effective registration statement under the Securities Act of
1933, as amended, in which the Corporation, prior to giving effect to the
proceeds of the Offering, is valued at least $135,000,000 (determined by
multiplying the number of outstanding shares of capital stock of the Corporation
on a fully diluted basis by the initial public offering price) and resulting in
at least $15,000,000 of net proceeds (determined by subtracting underwriters'
discounts and commissions from gross proceeds) to the Corporation.

               (2)  The holders of record of the shares of Series C Preferred
Stock, exclusively and as a separate class, shall be entitled to elect one
director of the Corporation ("Series C Director"), and, except as set forth in
(1) above, the holders of record of the shares of Common Stock and of any other
class or series of voting stock (including the Series A Preferred Stock, Series
B Preferred Stock and Series C Preferred Stock), exclusively and as a separate
class, shall be entitled to elect the balance of the total number of directors
of the Corporation- At any meeting held for the purpose of electing directors,
the presence in person or by proxy of the holders of a majority of the shares of
Series C Preferred Stock then outstanding shall constitute a quorum of the
Series C Preferred Stock for the purpose of electing the Series C Director by
holders of the Series C Preferred Stock. A vacancy in the Series C Director
directorship shall be filled only by vote or written consent in lieu of a
meeting of the holders of the Series C Preferred Stock. The rights of the
holders of the Series C Preferred Stock under this Subsection 3(b)(2) shall
commence on the date that the outstanding shares of Series C Preferred Stock
represent at least 5% of the outstanding shares of Common Stock, after giving
effect to the conversion into Common Stock of all outstanding shares of
convertible Preferred Stock, and shall terminate on the earlier of (i) the date
on which the outstanding shares of Series C Preferred Stock represent less than
5% of the outstanding shares of Common Stock, after giving effect to the
conversion into Common Stock of all outstanding shares of convertible Preferred
Stock, and (ii) the first anniversary of the closing of the sale by the
Corporation of shares of Common Stock in a public offering, underwritten by a
nationally recognized underwriter, pursuant to an effective registration
statement under the Securities Act of 1933, as amended, in which the
Corporation, prior to giving effect to the proceeds of the Offering, is valued
at at least $135,000,000 (determined by multiplying the number of outstanding
shares of capital stock of the Corporation on a fully diluted basis by the
initial public offering price) and resulting in at least $15,000,000 of net
proceeds (determined by subtracting underwriters' discounts and commissions from
gross proceeds) to the Corporation.

          (c)  The Corporation shall not amend, alter or repeal the preferences,
special rights or other powers of the Series A Preferred Stock, Series B
Preferred Stock or Series C

                                       31
<PAGE>

Preferred Stock so as to affect adversely the Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock, without the written consent or
affirmative vote of the holders of a majority of the then outstanding shares of
Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock,
respectively, given in writing or by vote at a meeting, consenting or voting (as
the case may be) separately as a class. For this purpose, without limiting the
generality of the foregoing, the authorization of any shares of capital stock
with preference or priority over the Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock as to redemption rights, voting
rights, the right to receive either dividends or amounts distributable upon
liquidation, dissolution or winding up of the Corporation, or otherwise, shall
be deemed to affect adversely the Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock, and the authorization of any shares of
capital stock on a parity with Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock as to the right to receive either dividends or
amounts distributable upon liquidation, dissolution or winding up of the
Corporation shall not be deemed to affect adversely the Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock, respectively. The
number of authorized shares of Series A Preferred Stock, Series B Preferred
Stock and Series C Preferred Stock may be increased or decreased (but not below
the number of shares dim outstanding) by the directors of the Corporation
pursuant to Section 151 of the General Corporation Law of Delaware or by the
affirmative vote of the holders of a majority of the then outstanding shares of
the Common Stock, Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and all other classes or series of stock of the Corporation
entitled to vote thereon, voting as a single class, irrespective of the
provisions of Section 242(b)(2) of the General Corporation Law of Delaware.

     4.   Optional Conversion.  The holders of the Series A Preferred Stock,
          -------------------
Series B Preferred Stock and Series C Preferred Stock shall have conversion
rights as follows (the "Conversion Rights"):

          (a)  Right to Convert.  Each share of Series A Preferred Stock, Series
               ----------------
B Preferred Stock and Series C Preferred Stock shall be convertible, at the
option of the holder thereof, at any time and from time to time, and without the
payment of additional consideration by the holder thereof, into such number of
fully paid and nonassessable shares of Common Stock as is determined by dividing
$4.00 by the Conversion Price (as defined below) in effect at the time of
conversion. The "Conversion Price" shall initially be $4.00. Such initial
Conversion Price, and the rate at which shares of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock may be converted into
shares of Common Stock, shall be subject to adjustment as provided below.

     In the event of a notice of redemption of any shares of Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock pursuant to Section
6 hereof, the Conversion Rights of the shares of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock, respectively, designated
for redemption shall terminate at the close of business on the fifth full day
preceding the date fixed for redemption, unless the redemption price is not paid
when due, in which case the Conversion Rights of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock for such shares shall
continue until such price is paid in full- In the event of a liquidation of the
Corporation, the Conversion Rights shall terminate at the close of business on
the first full day preceding the date fixed for the payment of any amounts
distributable on

                                       32
<PAGE>

liquidation to the holders of Series A Preferred Stock, Series B Preferred Stock
or Series C Preferred Stock, respectively.

          (b)  Fractional Shares.  No fractional shares of Common Stock shall be
               -----------------
issued upon conversion of the Series A Preferred Stock, Series B Preferred Stock
or Series C Preferred Stock. In lieu of any fractional shares to which the
holder would otherwise be entitled, the Corporation shall pay cash equal to such
fraction multiplied by the then effective Conversion Price.

          (c)  Mechanics of Conversion.
               -----------------------

               (i)   In order for a holder of Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock to convert shares of Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock into
shares of Common Stock, such holder shall surrender the certificate or
certificates for such shares of Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock, at the office of the transfer agent for the
Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock,
respectively (or at the principal office of the Corporation if the Corporation
serves as its own transfer agent), together with written notice that such holder
elects to convert all or any number of the shares of the Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock represented by such
certificate or certificates. Such notice shall state such holders name or the
names of the nominees in which such holder wishes the certificate or
certificates for shares of Common Stock to be issued. If required by the
Corporation, certificates surrendered for conversion shall be endorsed or
accompanied by a written instrument or instruments of transfer, in form
satisfactory to the Corporation, duly executed by the registered holder or his
or its attorney duly authorized in writing. The date of receipt of such
certificates and notice by the transfer agent (or by the Corporation if the
Corporation serves as its own transfer agent) shall be the conversion date
("Conversion Date") and such holder shall be treated as a record holder of
Common Stock on such date. The Corporation shall, as soon as practicable after
the Conversion Date, issue and deliver at such office to such holder of Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock, or to his
or its nominees, a certificate or certificates for the number of shares of
Common Stock to which such holder shall be entitled, together with cash in lieu
of any fraction of a share, and a certificate or certificates for the number of
shares of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock represented by the surrendered certificate but not converted.

               (ii)  The Corporation shall at all times when the Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock shall be
outstanding, reserve and keep available out of its authorized but unissued
stock, for the purpose of effecting the conversion of the Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock, such number of its
duly authorized shares of Common Stock as shall from time to time be sufficient
to effect the conversion of all outstanding Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock. Before taking any action which
would cause an adjustment reducing the Conversion Price below the then par value
of the shares of Common Stock issuable upon conversion of the Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock, the Corporation
will take any corporate action which may, in the opinion of its counsel, be

                                       33
<PAGE>

necessary in order that the Corporation may validly and legally issue fully paid
and nonassessable shares of Common Stock at such adjusted Conversion Price.

               (iii) Upon any such conversion, adjustment to the Conversion
Price of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock, shall be made for any declared but unpaid dividends on the
Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock,
respectively, surrendered for conversion or on the Common Stock delivered upon
conversion.

               (iv)  All shares of Series A Preferred Stock, Series B Preferred
Stock and Series C Preferred Stock which shall have been surrendered for
conversion as herein provided shall no longer be deemed to be outstanding and
all rights with respect to such shares, including the rights, if any, to receive
notices and to vote, shall immediately cease and terminate on the Conversion
Date, except only the right of the holders thereof to receive shares of Common
Stock in exchange therefor and payment of any dividends declared but unpaid
thereon. Any shares of Series A Preferred Stock, Series B Preferred Stock or
Series C Preferred Stock so converted shall be retired and cancelled and shall
not be reissued, and the Corporation (without the need for stockholder action)
may from time to time take such appropriate action as may be necessary to reduce
the authorized Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock accordingly.

               (v)   The Corporation shall pay any and all issue and other taxes
that may be payable in respect of any issuance or delivery of shares of Common
Stock upon conversion of shares of Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock pursuant to this Section 4. The Corporation
shall not, however, be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of shares of Common Stock
in a name other than that in which the shares of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock so converted were
registered, and, to the extent the Company would be required to pay such a tax,
no such issuance or delivery shall be made unless and until the person or entity
requesting such issuance has paid to the Corporation the amount of any such tax
or has established, to the satisfaction of the Corporation, that such tax has
been paid.

          (d)  Adjustments to Conversion Price for Diluting Issues:
               ---------------------------------------------------

                     (D)  "Additional Shares of Common Stock" shall mean all
                           ---------------------------------
shares of Common Stock issued (or, pursuant to Subsection 4(d)(iii) below,
deemed to be issued) by the Corporation after the Original Issue Date, other
than shares of Common Stock issued or issuable:

                          (I)   upon conversion of any Convertible Securities
outstanding on the Original Issue Date, or upon exercise of any Options
outstanding on the Original Issue Date;

                          (II)  as a dividend or distribution on Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock;

                          (III) by reason of a dividend, stock split, split-up
or other distribution on shares of Common Stock that is covered by Subsection
4(e) or 4(f) below; or

                          (IV)  to employees, officers or directors of, or

plans, provides for the issuance of no more than an aggregate of 1,500,000
shares of Common Stock (subject to appropriate adjustment in the event of any
stock dividend, stock split, combination or other similar recapitalization
affecting the Common Stock)).

               (ii)  No Adjustment of Conversion Price.  No adjustment in the
                     ---------------------------------
number of shares of Common Stock into which the Series A Preferred Stock, Series
B Preferred Stock, or Series C Preferred Stock is convertible shall be made, by
adjustment in the applicable Conversion Price thereof, unless the consideration
per share (determined pursuant to Subsection 4(d)(v)) for an Additional Share of
Common Stock issued or deemed to be issued by the Corporation is less than the
applicable Conversion Price in effect on the date of, and immediately prior to,
the issue of such Additional Shares.

               (iii) Issue of Securities Deemed Issue of Additional Shares of
                     --------------------------------------------------------
                     Common Stock.
                     ------------

     If the Corporation at any time or from time to time after the Original
Issue Date shall issue any Options or Convertible Securities or shall fix a
record date for the determination of holders of any class of securities entitled
to receive any such Options or Convertible Securities, then the maximum number
of shares of Common Stock (as set forth in the instrument relating thereto
without regard to any provision contained therein for a subsequent adjustment of
such number) issuable upon the exercise of such Options or, in the case of
Convertible Securities and Options therefor, the conversion or exchange of such
Convertible Securities, shall be deemed to be Additional Shares of Common Stock
issued as of the time of such issue or, in case such a record date shall have
been fixed, as of the dose of business on such record date, provided that
Additional Shares of Common Stock shall not be deemed to have been issued unless
the consideration per share (determined pursuant to Subsection 4(d)(v) hereof)
of such Additional Shares of Common Stock would be less than the applicable
Conversion Price in effect on the date of and immediately prior to such issue,
or such record date, as the case may be, and

                                       35
<PAGE>

provided further that in any such case in which Additional Shares of Common
Stock are deemed to be issued:

                     (A)  No further adjustment in the Conversion Price shall be
made upon the subsequent issue of Convertible Securities or shares of Common
Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                     (B)  If such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase in the
consideration payable to the Corporation, upon the exercise, conversion or
exchange thereof, the Conversion Price computed upon the original issue thereof
(or upon the occurrence of a record date with respect thereto), and any
subsequent adjustments based thereon, shall, upon any such increase becoming
effective, be recomputed to reflect such increase insofar as it affects such
Options or the rights of conversion or exchange under such Convertible
Securities;

                     (C)  Upon the expiration or termination of any unexercised
Option, the Conversion Price shall be readjusted, and the Additional Shares of
Common Stock deemed issued as the result of the original issue of such Option
shall not be deemed issued for the purposes of any subsequent adjustment of the
Conversion Price;

                     (D)  In the event of any change in the number of shares of
Common Stock issuable upon the exercise, conversion or exchange of any Option or
Convertible Security, including, but not limited to, a change resulting from the
anti-dilution provisions thereof, the Conversion Price then in effect shall
forthwith be readjusted to such Conversion Price as would have obtained had the
adjustment which was made upon the issuance of such Option or Convertible
Security prior to such change been made upon the basis of such change; and

                     (E)  No readjustment pursuant to clause (B), (C) or (D)
above shall have the effect of increasing the Conversion Price to an amount
which exceeds the lower of (i) the Conversion Price on the original adjustment
date, or (ii) the Conversion Price that would have resulted from any issuances
of Additional Shares of Common Stock between the original adjustment date and
such readjustment date.

     In the event the Corporation, after the Original Issue Date, amends the
terms of any Options or Convertible Securities (whether such Options or
Convertible Securities were outstanding on the Original Issue Date or were
issued after the Original Issue Date), then such Options or Convertible
Securities, as so amended, shall be deemed to have been issued after the
Original Issue Date and the provisions of this Subsection 4(d)(iii) shall apply.

               (iv)  Adjustment of Conversion Price Upon Issuance of Additional
                     ----------------------------------------------------------
                     Shares of Common Stock.
                     ----------------------

     In the event the Corporation shall at any time after the Original Issue
Date issue Additional Shares of Common Stock (including Additional Shares of
Common Stock deemed to be issued pursuant to Subsection 4(d)(iii), but excluding
shares issued as a stock split or combination as provided in Subsection 4(e) or
upon a dividend or distribution as provided in Subsection 4(f)), without
consideration or for a consideration per share less than the applicable

                                       36
<PAGE>

Conversion Price in effect on the date of and immediately prior to such
issuance, then and in such event, such Conversion Price shall be reduced,
concurrently with such issue, to a price (calculated to the nearest cent)
determined by multiplying such Conversion Price by a fraction, (A) the numerator
of which shall be (1) the number of shares of Common Stock outstanding
immediately prior to such issue plus (2) the number of shares of Common Stock
which the aggregate consideration received or to be received by the Corporation
for the total number of Additional Shares of Common Stock so issued would
purchase at such Conversion Price; and (B) the denominator of which shall be the
number of shares of Common Stock outstanding immediately prior to such issue
plus the number of such Additional Shares of Common Stock so issued; provided
                                                                     --------
that, (i) for the purpose of this Subsection 4(d)(iv), all shares of Common
- ----
Stock issuable upon exercise or conversion of Options (including the conversion
into Common Stock of Convertible Securities issuable upon the exercise of such
Options) or Convertible Securities outstanding immediately prior to such issue
shall be deemed to be outstanding, (ii) the number of shares of Common Stock
deemed issuable upon exercise or conversion of such outstanding Options and
Convertible Securities shall not give effect to any adjustments to the
conversion price or conversion rate of such Options or Convertible Securities
resulting from the issuance of Additional Shares of Common Stock that is the
subject of this calculation, and (iii) immediately after any Additional Shares
of Common Stock are deemed issued pursuant to Section 4(d)(iii), such Additional
Shares of Common Stock shall be, deemed to be outstanding.

               (v)   Determination of Consideration.  For purposes of this
                     ------------------------------
Subsection 4(d), the consideration received by the Corporation for the issue of
any Additional Shares of Common Stock shall be computed as follows:

                     (A)  Cash and Property:  Such consideration shall:
                          -----------------

                          (I)   insofar as it consists of cash, be computed at
the aggregate amount of cash received by the Corporation, excluding amounts paid
or payable for accrued interest or accrued dividends;

                          (II)  insofar as it consists of property other than
cash, be computed at the fair market value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and

                          (III) in the event Additional Shares of Common Stock
are issued together with other shares or securities or other assets of the
Corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (I) and (II) above,
as determined in good faith by the Board of Directors.

                     (B)  Options and Convertible Securities. The consideration
                          ----------------------------------
per share received by the Corporation for Additional Shares of Common Stock
deemed to have been issued pursuant to Subsection 4(d)(iii), relating to Options
and Convertible Securities, shall be determined by dividing

                          (x)   the total amount, if any, received or receivable
by the Corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating

                                       37
<PAGE>

thereto, without regard to any provision contained therein for a subsequent
adjustment of such consideration) payable to the Corporation upon the exercise
of such Options or the conversion or exchange of such Convertible Securities, or
in the case of Options for Convertible Securities, the exercise of such Options
for Convertible Securities and the conversion or exchange of such Convertible
Securities, by

                          (y)   the maximum number of shares of Common Stock (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

               (vi)  Multiple Closing Dates.  In the event the Corporation shall
                     ----------------------
issue on more than one date Additional Shares of Common Stock which are
comprised of shares of the same series or class of Preferred Stock, and such
issuance dates occur within a period of no more than 120 days, then the
Conversion Price shall be adjusted only once on account of such issuances, with
such adjustment to occur upon the final such issuance and to give effect to all
such issuances as if they occurred on the date of the final such issuance.

          (e)  Adjustment for Stock Splits and Combinations.  If the Corporation
               --------------------------------------------
shall at any time or from time to time after the Original Issue Date effect a
subdivision of the outstanding Common Stock into a greater number of shares of
Common Stock (by reclassification or otherwise than by payment of a dividend in
Common Stock), the Conversion Price then in effect immediately before that
subdivision shall be proportionately decreased. If the Corporation shall at any
time or from time to time after the Original Issue Date combine the outstanding
shares of Common Stock into a lesser number of shares of Common Stock, the
Conversion Price then in effect immediately before the combination shall be
proportionately increased. Any adjustment under this paragraph shall become
effective at the close of business on the date the subdivision or combination
becomes effective.

          (f)  Adjustment for Certain Dividends and Distributions.  In the event
               --------------------------------------------------
the Corporation at any time, or from time to time after the Original Issue Date
shall make or issue, or fix 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, then and in each such event the Conversion
Price for the Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock then in effect shall be decreased as of the time of such
issuance or, in the event such a record date shall have been fixed, as of the
close of business on such record date, by multiplying the Conversion Price for
the Series A Preferred Stock, Series B Preferred Stock or Series C Preferred
Stock, as applicable, then in effect by a fraction:

               (1)   the numerator of which shall be 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

               (2)   the denominator of which shall be 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

                                       38
<PAGE>

          record date plus the number of shares of Common Stock
          issuable in payment of such dividend or distribution;

provided, however, if such record date shall have been fixed and such dividend
is not fully paid or if such distribution is not fully made on the date fixed
therefor, the Conversion Price for the Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock shall be recomputed accordingly as
of the close of business on such record date and thereafter the Conversion Price
for the Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock shall be adjusted pursuant to this paragraph as of the time of
actual payment of such dividends or distributions; and provided further,
however, that no such adjustment shall be made to Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock if the holders of Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock,
respectively, simultaneously receive a dividend or other distribution of shares
of Common Stock in a number equal to the number of shares of Common Stock as
they would have received if all, outstanding shares of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock, respectively, had been
converted into Common Stock on the date of such event.

          (g)  Adjustments for Other Dividends and Distributions.  In the event
               -------------------------------------------------
the Corporation at any time or from time to time after the Original Issue Date
for the Series A Preferred Stock, Series B Preferred Stock or Series C Preferred
Stock shall make or issue, or fix a record date for the determination of holders
of Common Stock entitled to receive, a dividend or other distribution payable in
securities of the Corporation other than shares of Common Stock, then and in
each such event provision shall be made so that the holders of the Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock,
respectively, shall receive upon conversion thereof in addition to the number of
shares of Common Stock receivable thereupon, the amount of securities of the
Corporation that they would have received had the Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock, respectively, 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, giving application to all adjustments called for during such period
under this paragraph with respect to the rights of the holders of the Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock; and
provided further, however, that no such adjustment to the Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock shall be made if the
holders of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock, respectively, simultaneously receive a dividend or other
distribution of such securities in an amount equal to the amount of such
securities as they would have received if all outstanding shares of Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock,
respectively, had been converted into Common Stock on the date of such event.

          (h)  Adjustment for Reclassification, Exchange, or Substitution.  If
               ----------------------------------------------------------
the Common Stock issuable upon the conversion of the Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock shall be changed into the
same or a different number of shares of any class or classes of stock, whether
by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares or stock dividend provided for above, or a
reorganization, merger, consolidation, or sale of assets provided for below),
then and in each such event the holder of each such share of Series A Preferred
Stock, Series B Preferred Stock or

                                       39
<PAGE>

Series C Preferred Stock, respectively, shall have the right thereafter to
convert such share into the kind and amount of shares of stock and other
securities and property receivable upon such reorganization, reclassification,
or other change, by holders of the number of shares of Common Stock into which
such shares of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock, respectively, might have been converted immediately prior to
such reorganization, reclassification, or change, all subject to further
adjustment as provided herein.

          (i)  Adjustment for Merger or Reorganization, etc.  In case of any
               --------------------------------------------
consolidation or merger of the Corporation with or into another corporation or
the sale or transfer of all or substantially all of the assets of the
Corporation to another corporation, each share of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock shall thereafter be
convertible into the kind and amount of shares of stork or other securities or
property to which a holder of the number of shares of Common Stock of the
Corporation deliverable upon conversion of such Series A Preferred Stock, Series
B Preferred Stock and Series C Preferred Stock, respectively, would have been
entitled upon such consolidation, merger, sale or transfer; and, in such case,
appropriate adjustment (as determined in good faith by the Board of Directors)
shall be made in the application of the provisions in this Section 4 set forth
with respect to the rights and interest thereafter of the holders of the Series
A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock, to the
end that the provisions set forth in this Section 4 (including provisions with
respect to changes in and other adjustments of the Conversion Price) shall
thereafter be applicable, as nearly as reasonably may be, in relation to any
shares of stock or other property thereafter deliverable upon the conversion of
the Series A Preferred Stock, Series B Preferred Stock or Series C Preferred
Stock, respectively. Each holder of Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock, upon the occurrence of a merger or
consolidation of the Corporation into or with another corporation (where the
Corporation is not the surviving entity and where the stockholders of the
Corporation fail to hold a majority of the voting securities of the surviving
corporation) or the sale or all or substantially all of the assets of the
Corporation, shall have the option of electing treatment of his shares of Series
A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock under
either this Section 4(i) or Section 2(c) hereof.

          (j)  No Impairment.  The Corporation will not, by amendment of its
               -------------
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation, but will at
all times in good faith assist in the carrying out of all the provisions of this
Section 4 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of the
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
against impairment.

          (k)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Conversion Price pursuant to this Section 4,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each holder of
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
a certificate setting forth such adjustment or readjustment and showing in
detail the facts upon which such adjustment or readjustment is based.  The
Corporation shall, upon the written request at any time of any holder of Series
A Preferred Stock, Series B Preferred Stock or

                                       40
<PAGE>

Series C Preferred Stock, furnish or cause to be furnished to such holder a
similar certificate setting forth (i) such adjustments and readjustments, (ii)
the Conversion Price then in effect and (iii) the number of shares of Common
Stock and the amount, if any, of other property which then would be received
upon the conversion of Series A Preferred Stock, Series B Preferred Stock or
Series C Preferred Stock.

          (l)  Notice of Record Date.  In the event:
               ---------------------

               (i)   that the Corporation declares a dividend (or any other
distribution) on its Common Stock, whether in cash, property, stock or other
securities;

               (ii)  that the Corporation offers for subscription pro rata to
the holders of any class or series of its capital stock any additional shares of
stock of any class or series or other rights;

               (iii) that the Corporation subdivides or combines its outstanding
shares of Common Stock;

               (iv)  of any reclassification of the Common Stock of the
corporation (other than a subdivision or combination of its outstanding shares
of Common Stock or a stock dividend or stock distribution thereon), or of any
consolidation or merger of the Corporation into or with another corporation, or
of the sale of all or substantially all of the assets of the Corporation; or

               (v)   of the involuntary or voluntary dissolution, liquidation or
winding up of the Corporation;

then the Corporation shall cause to be filed at its principal office or at the
office of the transfer agent of the Series A Preferred Stock, Series B Preferred
Stock and Series C Preferred Stock, and shall cause to be mailed by first class
mail postage prepaid to the holders of the Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock at their last addresses as shown on
the records of the Corporation or such transfer agent, at least twenty (20) days
prior to the date specified in (A) below or twenty days before the date
specified in (B) below, a notice stating

          (A)  the record date of such dividend, distribution, subscription
               right, subdivision or combination, or, if a record is not to be
               taken, the date as of which the holders of Common Stock of record
               to be entitled to such dividend, distribution, subdivision or
               combination are to be determined, or

          (B)  the date on which such reclassification, consolidation, merger,
               sale, dissolution, liquidation or winding up is expected to
               become effective, and the date as of which it is expected that
               holders of Common Stock of record shall be entitled to exchange
               their shares of Common Stock for securities or other property
               deliverable upon such reclassification, consolidation, merger,
               sale, dissolution or winding up.

     5.   Mandatory Conversion.
          --------------------

          (a)  Upon the closing of the sale of shares of Common Stock in a
public offering underwritten by a nationally recognized underwriter, pursuant to
an effective registration statement under the Securities Act of 1933, as
amended, in which the Corporation, prior to giving effect to the proceeds of the
Offering, is valued at at least $135,000,000 (determined by multiplying the
number of outstanding shares of capital stock of the Corporation on a fully
diluted basis by the initial public offering price) and resulting in at least
$15,000,000 of net proceeds (determined by subtracting underwriters' discounts
and commissions from gross proceeds) to the Corporation (the "Mandatory
Conversion Date"), (i) all outstanding shares of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock shall automatically be
converted into shares of Common Stock, at the then effective conversion rate and
(ii) the number of authorized shares of Preferred Stock shall be automatically
reduced by the number of shares of Preferred Stock that had been designated as
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock,
and all provisions included under the caption "Series A, B and C Convertible
Preferred Stock" and all references to the Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock shall be deleted and shall be of no
further force or effect.

          (b)  All holders of record of shares of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock shall be given written
notice of the Mandatory Conversion Date and the place designated for mandatory
conversion of all such shares of Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock, respectively, pursuant to this Section 5.
Such notice need not be given in advance of the occurrence of the Mandatory
Conversion Date. All holders of record of shares of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock shall be given written
notice of the filing by the Corporation of a registration statement under the
Securities Act of 1933, as amended, in connection with which the Corporation is
proposing to undertake a public offering, the closing date of which would be the
"Mandatory Conversion Date" as defined in paragraph (a) above. Such notice shall
be given within ten days following the filing of such registration statement.
Any notice required pursuant to this paragraph (b) shall be sent by first class
or registered mail, postage prepaid, to each record holder of Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock at such holder's
address last shown on the records of the transfer agent for the Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock (or the
records of the Corporation, if it serves as its own transfer agent). Upon
receipt of such notice, each holder of shares of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock shall surrender his or its
certificate or certificates for all such shares to the Corporation at the place
designated in such notice, and shall thereafter receive certificates for the
number of shares of Common Stock to which such holder is entitled pursuant to
this Section 5. On the Mandatory Conversion Date, all rights with respect to the
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
so converted, including the rights, if any, to receive notices and vote (other
than as a holder of Common Stock) will terminate, except only the rights of the
holders thereof, upon surrender of their certificate or certificates therefor,
to receive certificates for the number of shares of Common Stock into which such
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
has been converted, and payment of any declared but unpaid dividends thereon. If
so required by the Corporation, certificates surrendered for conversion shall be
endorsed or accompanied by written instrument or instruments of transfer, in

form satisfactory to the Corporation, duly executed by the registered holder or
by his or its attorney duly authorized in writing. As soon as practicable after
the Mandatory Conversion Date and the surrender of the certificate or
certificates for Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock, the Corporation shall cause to be issued and delivered to such
holder, or on his or its written order, a certificate or certificates for the
number of full shares of Common Stock issuable on such conversion in accordance
with the provisions hereof and cash as provided in Subsection 4(b) in respect of
any fraction of a share of Common Stock otherwise issuable upon such conversion.

          (c)  All certificates evidencing shares of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock which are required to be
surrendered for conversion in accordance with the provisions hereof shall, from
and after the Mandatory Conversion Date, be deemed to have been retired and
cancelled and the shares of Series A Preferred Stock, Series B Preferred Stock
and Series C Preferred Stock represented thereby converted into Common Stock for
all purposes, notwithstanding the failure of the holder or holders thereof to
surrender such certificates on or prior to such date. The Corporation may
thereafter take such appropriate action (without the need for stockholder
action) as may be necessary to reduce the authorized Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock accordingly.

     6.   Mandatory Redemption.
          --------------------

          (a)  The Corporation will, subject to the conditions set forth in
Subsection 6(b) below, upon the request of any holder of the Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock delivered in writing
to the Company at least six (6) months prior to the applicable Mandatory
Redemption Date (as defined below) in accordance with Section 6(c) below, on
June 30, 2000 and on each of the first and second anniversaries thereof (each
such date being referred to hereinafter as a Mandatory Redemption Date"), redeem
from such holder of shares of Series A Preferred Stock, Series B Preferred Stock
and Series C Preferred Stock, at a price equal to (i) in the case of Series A
Preferred Stock and Series C Preferred Stock, $4.00 per share, and in the case
of Series B Preferred Stock, $6.00 per share, plus accrued interest at a rate
equal to the "prime rate" of Citibank, N.A., as announced from time to time,
plus 2% per annum, plus (ii) any dividends declared but unpaid thereon, subject
to appropriate adjustment in the event of any stock dividend, stock split,
combination or other similar recapitalization affecting such shares (the
"Mandatory Redemption Price"), the following respective portions of the
aggregate number of shares of Series A Preferred Stock, Series B Preferred Stock
and Series C Preferred Stock held by such holder for which Corporation received
cash in payment for the issuance and sale thereof, on the applicable Mandatory
Redemption Date:

                         Portion of Shares of Series A, B and C
Redemption Date              Preferred Stock To Be Redeemed
- ---------------              ------------------------------

June 30, 2000                             33%

June 30, 2001        Any shares of Series A, B and C Preferred
                     Stock entitled to be redeemed on the first
                     Mandatory Redemption Date that were not
                     redeemed plus 50% of all remaining shares

                                       43
<PAGE>

                     of Series A, B and C Preferred Stock

June 30, 2002        100% (or all remaining shares of Series A, B
                     and C Preferred Stock)

          (b)  If the funds of the Corporation legally available for redemption
of Series A Preferred Stock, Series B Preferred Stock and Series C Preferred
Stock on any Mandatory Redemption Date are insufficient to redeem the number of
shares of Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock required under this Section 6 to be redeemed on such date, those
funds which are legally available will be used to redeem the maximum possible
number of such shares of Series A Preferred Stock, Series B Preferred Stock and
Series C Preferred Stock ratably on the basis of the number of shares of Series
A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock which
would be redeemed on such date if the funds of the Corporation legally available
therefor bad been sufficient to redeem all shares of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock required to be redeemed on
such date. At any time thereafter when additional funds of the Corporation
become legally available for the redemption of Series A Preferred Stock, Series
B Preferred Stock and Series C Preferred Stock, such funds will be used, at the
end of the next succeeding fiscal quarter, to redeem the balance of the shares
which the Corporation was theretofore obligated to redeem, or such portion
thereof for which funds are available, ratably on the basis set forth in the
preceding sentence.

          (c)  The holder of Series A Preferred Stock, Series B Preferred Stock
or Series C Preferred Stock requesting redemption shall, provide notice of any
redemption of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock pursuant to this Section 6, by registered mail, postage prepaid,
to the Corporation not less than six (6) months prior to the date on which such
redemption is to be made. The notice will specify the number of shares which are
to be redeemed. Upon receipt of any such notice of redemption, the Corporation
will become obligated to redeem on the applicable Mandatory Redemption Date all
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
specified therein (other than such shares of Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock as are duly converted pursuant to
Section 4 prior to the close of business on the fifth full day preceding the
Mandatory Redemption Date). In case less than all Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock represented by any
certificate is redeemed in any redemption pursuant to this Section 6, a new
certificate will be issued representing the unredeemed Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock without cost to the holder
thereof.

          (d)  Unless there shall have been a default in payment of the
Mandatory Redemption Price, no share of Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock that is redeemed shall be entitled
to any dividends declared after its Mandatory Redemption Date, and on such
Mandatory Redemption Date all rights of the holder of such share as a
stockholder of the Corporation by reason of the ownership of such share will
cease, except the right to receive the Mandatory Redemption Price of such share,
without interest, upon presentation and surrender of the certificate
representing such share, and such share will not from and after such Mandatory
Redemption Date be deemed to be outstanding.

                                       44
<PAGE>

          (e)  Any Series A Preferred Stock, Series B Preferred Stock or Series
C Preferred Stock redeemed pursuant to this Section 6 will be cancelled and will
not under any circumstances he reissued, sold or transferred and the Corporation
may from time to time take such appropriate action as may be necessary to reduce
the authorized Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock accordingly.

     IN WITNESS WHEREOF, the Corporation has caused its corporate seal to be
affixed hereto and this Certificate of Amendment to be signed by its President
this 20/th/ day of February, 1998.

corporation or entity (where the Corporation is not the surviving entity and

winding up of the Corporation within the meaning of this Section 2; provided,
                                                                    --------

Preferred Stock held by such holder are then convertible (as adjusted from time
to time pursuant to Section 4 hereof), at each meeting of stockholders of the
Corporation (and written actions of stockholders in lieu of meetings) with
respect to any and all matters presented to the stockholders of the Corporation
for their action or consideration.  Except as provided by law, by the provisions
of Subsection 3(b) or 3(c) below or by the provisions establishing any other
series of Preferred Stock, holders of Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock and of any other outstanding series
of Series Preferred Stock shall vote together with the holders of Common Stock
as a single class.

          (b)  The Corporation shall not amend, alter or repeal the preferences,
special rights or other powers of the Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock so as to affect adversely the Series
A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock, without
the written consent or affirmative vote of the holders of a majority of the then
outstanding shares of Series A Preferred Stock, Series B Preferred Stock or
Series C Preferred Stock, respectively, given in writing or by vote at a
meeting, consenting or voting (as the case may be) separately as a class.  For
this purpose, without limiting the generality of the foregoing, the
authorization of any shares of capital stock with preference or

                                       49
<PAGE>

priority over the Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock as to redemption rights, voting rights or the right to receive
either dividends or amounts distributable upon liquidation, dissolution or
winding up of the Corporation or otherwise shall be deemed to affect adversely
the Series A Preferred Stock, Series B Preferred Stock or Series C Preferred
Stock, and the authorization of any shares of capital stock on a parity with
Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock
as to redemption rights, voting rights or the right to receive either dividends

Corporation shall not be deemed to affect adversely the Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock, respectively.
Notwithstanding the foregoing, the authorization of any shares of capital stock

Stock, the Series B Preferred Stock and the Series C Preferred Stock, except for
being entitled to a per share redemption price higher than that applicable to
the Series A Preferred Stock, the Series B Preferred Stock or the Series C
Preferred Stock, if such higher per share redemption price is equivalent to the
per share purchase price for such shares, (b) containing voting rights similar
to those of the Series A Preferred Stock, the Series B Preferred Stock and the
Series C Preferred Stock, except for being entitled, exclusively and as a
separate class, to (i) elect one or more directors of the Corporation and (ii)
rights relating to such election or (c) containing rights upon liquidation,
dissolution or winding up of the Corporation similar to those of the Series A
Preferred Stock, the Series B Preferred Stock and the Series C Preferred Stock,
except for being entitled to be paid out of the assets of the Corporation a per
share amount higher than that applicable to the Series A Preferred Stock, the
Series B Preferred Stock or the Series C Preferred Stock, if such per share
amount is equivalent to the per share purchase price for such shares, shall not
be deemed to affect adversely the Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock. The number of authorized shares of Series A
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock may be
increased or decreased (but not below the number of shares then outstanding) by
the directors of the Corporation pursuant to Section 151 of the General
Corporation Law of Delaware or by the affirmative vote of the holders of a
majority of the then outstanding shares of the Common Stock, Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock and all other classes
or series of stock of the Corporation entitled to vote thereon, voting as a
single class, irrespective of the provisions of Section 242(b)(2) of the General
Corporation Law of Delaware.

          -------------------
Series B Preferred Stock and Series C Preferred Stock shall have conversion
rights as follows (the "Conversion Rights"):

          (a)  Right to Convert.  Each share of Series A Preferred Stock, Series
               ----------------
B Preferred Stock and Series C Preferred Stock shall be convertible, at the
option of the holder thereof, at any time and from time to time, and without the
payment of additional consideration by the holder thereof, into such number of
fully paid and nonassessable shares of Common Stock as is determined by dividing
$4.00 by the Conversion Price (as defined below) in effect at the time of
conversion.  The "Conversion Price" shall initially be $4.00.  Such initial
Conversion Price, and the rate at which shares of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock may be converted into
shares of Common Stock, shall be subject to adjustment as provided below.

                                       50
<PAGE>

     In the event of a notice of redemption of any shares of Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock pursuant to Section
6 hereof, the Conversion Rights of the shares of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock, respectively, designated
for redemption shall terminate at the close of business on the fifth full day
preceding the date fixed for redemption, unless the redemption price is not paid
when due, in which case the Conversion Rights of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock for such shares shall
continue until such price is paid in full.  In the event of a liquidation of the
Corporation, the Conversion Rights shall terminate at the close of business on
the first full day preceding the date fixed for the payment of any amounts
distributable on liquidation to the holders of Series A Preferred Stock, Series
B Preferred Stock or Series C Preferred Stock, respectively.

          (b)  Fractional Shares.  No fractional shares of Common Stock shall be
               -----------------
issued upon conversion of the Series A Preferred Stock, Series B Preferred Stock
or Series C Preferred Stock.  In lieu of any fractional shares to which the
holder would otherwise be entitled, the Corporation shall pay cash equal to such
fraction multiplied by the then effective Conversion Price.

          (c)  Mechanics of Conversion.
               -----------------------

               (i)  In order for a holder of Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock to convert shares of Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock into
shares of Common Stock. such holder shall surrender the certificate or
certificates for such shares of Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock, at the office of the transfer agent for the
Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock,
respectively (or at the principal office of the Corporation if the Corporation
serves as its own transfer agent), together with written notice that such holder
elects to convert all or any number of the shares of the Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock represented by such
certificate or certificates.  Such notice shall state such holder's name or the
names of the nominees in which such holder wishes the certificate or
certificates for shares of Common Stock to be issued.  If required by the
Corporation, certificates surrendered for conversion shall be endorsed or
accompanied by a written instrument or instruments of transfer, in form
satisfactory to the Corporation, duly executed by the registered holder or his
or its attorney duly authorized in writing.  The date of receipt of such
certificates and notice by the transfer agent (or by the Corporation if the
Corporation serves as its own transfer agent) shall be the conversion date
("Conversion Date") and such holder shall be treated as a record holder of
Common Stock on such date.  The Corporation shall, as soon as practicable after
the Conversion Date, issue and deliver at such office to such holder of Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock, or to his
or its nominees, a certificate or certificates for the number of shares of
Common Stock to which such holder shall be entitled, together with cash in lieu
of any fraction of a share, and a certificate or certificates for the number of
shares of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock represented by the surrendered certificate but not converted.

               (ii) The Corporation shall at a times when the Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock shall be
outstanding, reserve and

                                       51
<PAGE>

keep available out of its authorized but unissued stock, for the purpose of
effecting the conversion of the Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock, such number of its duly authorized shares of
Common Stock as shall from time to time be sufficient to effect the conversion
of all outstanding Series A Preferred Stock, Series B Preferred Stock or Series
C Preferred Stock. Before taking any action which would cause an adjustment
reducing the Conversion Price below the then par value of the shares of Common
Stock issuable upon conversion of the Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock, the Corporation will take any
corporate action which may, in the opinion of its counsel, be necessary in order
that the Corporation may validly and legally issue fully paid and nonassessable
shares of Common Stock at such adjusted Conversion Price.

               (iii)Upon any such conversion, adjustment to the Conversion Price
of Series A Preferred Stock, Series B Preferred Stock or Series C Preferred
Stock, shall be made for any declared but unpaid dividends on the Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock,
respectively, surrendered for conversion or on the Common Stock delivered upon
conversion.

               (iv) All shares of Series A Preferred Stock, Series B Preferred
Stock and Series C Preferred Stock which shall have been surrendered for
conversion as herein provided shall no longer be deemed to be outstanding and
all rights with respect to such shares, including the rights, if any, to receive
notices and to vote, shall immediately cease and terminate on the Conversion
Date, except only the right of the holders thereof to receive shares of Common
Stock in exchange therefor and payment of any dividends declared but unpaid
thereon. Any shares of Series A Preferred Stock, Series B Preferred Stock or
Series C Preferred Stock so converted shall be retired and cancelled and shall
not be reissued, and the Corporation (without the need for stockholder action)
may from time to time take such appropriate action as may be necessary to reduce
the authorized Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock accordingly.

               (v)  The Corporation shall pay any and all issue and other taxes
that may be payable in respect of any issuance or delivery of shares of Common
Stock upon conversion of shares of Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock pursuant to this Section 4. The Corporation
shall not, however, be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of shares of Common Stock
in a name other than that in which the shares of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock so converted were
registered, and to the extent the Company would be required to pay such a tax,
no such issuance or delivery shall be made unless and until the person or entity
requesting such Issuance has paid to the Corporation the amount of any such tax
or has established, to the satisfaction of the Corporation, that such tax has
been paid.

                              outstanding on the Original Issue Date, or upon

                              pursuant to a plan adopted by the Board of

                              no more than an aggregate of 1,500,000 shares of
                              Common Stock (subject to appropriate adjustment in

                              affecting the Common Stock).

                    ---------------------------------
number of shares of Common Stock into which the Series A Preferred Stock, Series
B Preferred Stock, or Series C Preferred Stock is convertible shall be made, by
adjustment in the applicable Conversion Price thereof, unless the consideration
per share (determined pursuant to Subsection 4(d)(v)) for an Additional Share of
Common Stock issued or deemed to be issued by the Corporation is less than the
applicable Conversion Price in effect on the date of, and immediately prior to,
the issue of such Additional Shares.

               (iii)Issue of Securities Deemed Issue of Additional Shares of
                    --------------------------------------------------------
                    Common Stock.
                    ------------

     If the Corporation at any time or from time to time after the Original
Issue Date shall any Options or Convertible Securities or shall fix a record
date for the determination of holders of any class of securities entitled to
receive any such Options or Convertible Securities, then the maximum number of
shares of Common Stock (as set forth in the instrument relating thereto without
regard to any provision contained therein for a subsequent adjustment of such
number) issuable upon the exercise of such Options or, in the case of
Convertible Securities and Options therefor, the conversion or exchange of such
Convertible Securities, shall be deemed to be Additional Shares of Common Stock
issued as of the time of such issue or, in case such a record date shall have
been fixed, as of the close of business on such record date, provided that
Additional Shares of Common Stock shall not be deemed to have been issued unless
the consideration per share (determined pursuant to Subsection 4(d)(v) hereof
hereto of such Additional Shares of Common Stock would be less than the
applicable Conversion Price in effect on the date of and immediately prior to
such issue, or such record date, as the case may be, and provided further than
in any such case in which Additional Shares of Common Stock are deemed to be
issued:

                    (A)  No further adjustment in the Conversion Price shall be
made upon the subsequent issue of Convertible Securities or shares of Common
Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                    (B)  If such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase in the
consideration payable to the Corporation, upon the exercise, conversion or
exchange thereof, the Conversion Price computed upon the original issue thereof
(or upon the occurrence of a record date with respect thereto), and any
subsequent adjustments based thereon, shall, upon any such increase becoming
effective, be recomputed to reflect such increase insofar as it affects such
Options or rights of conversion or exchange under such Convertible Securities;

                    (C)  Upon the expiration or termination of any unexercised
Option, the Conversion Price shall be readjusted, and the Additional Shares of
Common Stock deemed issued as the result of the original issue of such Option
shall not be deemed issued for the purposes of any subsequent adjustment of the
Conversion Price;

                    (D)  In the event of any change in the number of shares of
Common Stock issuable upon the exercise, conversion or exchange of any Option or
Convertible Security, including, but not limited to, a change resulting from the
anti-dilution provisions thereof, the Conversion Price then in effect shall
forthwith be readjusted to such Conversion Price as would have obtained had the
adjustment which was made upon the issuance of such Option or Convertible
Security prior to such change been made upon the basis of such change; and

                    (E)  No readjustment pursuant to clause (B), (C) or (D)
above shall have the effect of increasing the Conversion Price to an amount
which exceeds the lower of (i) the Conversion Price on the original adjustment
date, or (ii) the Conversion Price that would

                                       54
<PAGE>

have resulted from any issuances of Additional Shares of Common Stock between
the original adjustment date and such readjustment date.

     In the event the Corporation, after the Original Issue Date, amends the
terms of any Options or Convertible Securities (whether such Options or
Convertible Securities were outstanding on the Original Issue Date or were
issued after the Original Issue Date), then such Options or Convertible
Securities, as so amended, shall be deemed to have been issued after the
Original Issue Date and the provisions of this Subsection 4 (d) (iii) shall
apply,

               (iv) Adjustment of Conversion Price Upon Issuance of Additional
                    ----------------------------------------------------------
                    Shares of Common Stock.
                    ----------------------

     In the event the Corporation shall at any time after the Original Issue
Date issue Additional Shares of Common Stock (including Additional Shares of
Common Stock deemed to be Issued pursuant to Subsection 4(d) (iii), but
excluding shares issued as a stock split or combination as provided in
Subsection 4(e) or upon a dividend or distribution as provided in Subsection
4(b), without consideration or for a consideration per share less than the
applicable Conversion Price in effect on the date of and immediately prior to
such issuance, then and in such event, such Conversion Price shall be reduced,
concurrently with such issue, to a price (calculated to the nearest cent)
determined by multiplying such Conversion Price by a fraction, (A) the numerator
of which shall be (1) the number of shares of Common Stock outstanding
immediately prior to such issue plus (2) the number of shares of Common Stock
which the aggregate consideration received or to be received by the Corporation
for the total number of Additional Shares of Common Stock so issued would
purchase at such Conversion Price; and (B) the denominator of which shall be the
number of shares of Common Stock outstanding immediately prior to such issue
plus the number of such Additional Shares of Common Stock so issued; provided
                                                                     --------
that (i) for the purpose of this Subsection 4(d)(iv), all shares of Common Stock
- ----
issuable upon exercise or conversion of Options (including the conversion into
Common Stock of Convertible Securities issuable upon the exercise of such
Options) or Convertible Securities outstanding immediately prior to such issue
shall be deemed to be outstanding, (ii) the number of shares of Common Stock
deemed issuable upon exercise or conversion of such outstanding Options and
Convertible Securities shall not give effect to any adjustments to the
conversion price or conversion rate of such Options or Convertible Securities
resulting from the issuance of Additional Shares of Common Stock that is the
subject of this calculation, and (iii) immediately after any Additional Shares
of Common Stock are deemed issued pursuant to Section 4(d)(iii), such Additional
Shares of Common Stock shall be deemed to be outstanding.

               (v)  Determination of Consideration.  For purposes of this
                    ------------------------------
Subsection 4(d), the consideration received by the Corporation for the issue of
any Additional Shares of Common Stock shall be computed as follows:

                    (A)  Cash and Property: Such consideration shall:
                         -----------------

                         (I)  insofar as it consists of cash, be computed at the
aggregate amount of cash received by the Corporation, excluding amounts paid or
payable for accrued interest or accrued dividends;

                                       55
<PAGE>

                         (II) insofar as it consists of property other than
cash, be computed at the fair market value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and

                         (III)in the event Additional Shares of Common Stock
are issued together with other shares or securities or other assets of the
Corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (I) and (II) above,
as determined in good faith by the Board of Directors.

                    (B)  Options and Convertible Securities.  The consideration
                         ----------------------------------
per share received by the Corporation for Additional Shares of Common Stock
deemed to have been issued pursuant to Subsection 4(d)(iii), relating to Options
and Convertible Securities, shall be determined by dividing

                         (x)  the total amount, if any, received or receivable
by the Corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration) payable to
the Corporation upon the exercise of such Options or the conversion or exchange
of such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the
conversion or exchange of such Convertible Securities, by

                         (y)  the maximum number or shares of Common Stock (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

               (vi) Multiple Closing Dates.  In the event the Corporation shall
                    ----------------------
issue on more than one date Additional Shares of Common Stock which are
comprised of shares of the same series or class of Preferred Stock, and such
issuance dates occur within a period of no more than 120 days, then the
Conversion Price shall be adjusted only once on account of such issuances, with
such adjustment to occur upon the final such issuance and to give effect to all
such issuances as if they occurred on the date of the final such issuance.

          (e)  Adjustment for Stock Splits and Combinations.  If the Corporation
               --------------------------------------------
shall at any time or from time to time after the Original Issue Date effect a
subdivision of the outstanding Common Stock into a greater number of shares of
Common Stock (by reclassification or otherwise than by payment of a dividend in
Common Stock), the Conversion Price then in effect immediately before that
subdivision shall be proportionately decreased.  If the Corporation shall at any
time or from time to time after the Original Issue Date combine the outstanding
shares of Common Stock into a lesser number of shares of Common Stock, the
Conversion Price then in effect immediately before the combination shall be
proportionately increased.  Any adjustment under this paragraph shall become
effective at the close of business on the date the subdivision or combination
becomes effective.

                                       56
<PAGE>

          (f)  Adjustment for Certain Dividends and Distributions.  In the event
               --------------------------------------------------
the Corporation at any time, or from time to time after the Original Issue Date
shall make or issue, or fix 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, then and in each such event the Conversion
Price for the Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock then in effect shall be decreased as of the time of such
issuance or, in the event such a record date shall have been fixed, as of the
close of business on such record date, by multiplying the Conversion Price for
the Series A Preferred Stock, Series B Preferred Stock or Series C Preferred
Stock, as applicable, then in effect by a fraction:

               (1)  the numerator of which shall be 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

               (2)  the denominator of which shall be 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, if such record date shall have been fixed and such dividend
is not fully paid or if such distribution is not fully made on the date fixed
therefor, the Conversion price for the Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock shall be recomputed accordingly as
of the close of business on such record date and thereafter the Conversion Price
for the Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock shall be adjusted pursuant to this paragraph as of the time of
actual payment of such dividends or distributions; and provided further,
however, that no such adjustment shall be made to Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock if the holders of Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock,
respectively, simultaneously receive a dividend or other distribution of shares
of Common Stock in a number equal to the number of shares of Common Stock as
they would have received if all outstanding shares of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock, respectively, had been
converted into Common Stock on the date of such event.

          (g)  Adjustments for Other Dividends and Distributions.  In the event
               -------------------------------------------------
the Corporation at any time or from time to time after the Original Issue Date
for the Series A Preferred Stock, Series B Preferred Stock or Series C Preferred
Stock shall make or issue, or fix a record date for the determination of holders
of Common Stock entitled to receive, a dividend or other distribution payable in
securities of the Corporation other than shares of Common Stock, then and in
each such event provision shall be made so that the holders of the Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock,
respectively, shall receive upon conversion thereof in addition to the number of
shares of Common Stock receivable thereupon, the amount of securities of the
Corporation that they would have received had the Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock, respectively, 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, giving application to all adjustments called for during such period
under this paragraph with respect to the rights of the holders of the Series

                                       57
<PAGE>

A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock; and
provided further, however, that no such adjustment to the Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock shall be made if the
holders of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock, respectively, simultaneously receive a dividend or other
distribution of such securities in an amount equal to the amount of such
securities as they would have received if all outstanding shares of Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock,
respectively, had been converted into Common Stock on the date of such event.

          (h)  Adjustment for Reclassification, Exchange or Substitution.  If
               ---------------------------------------------------------
the Common Stock issuable upon conversion of the Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock shall be changed into the
same or a different number of shares of any class or classes of stock, whether
by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares or stock dividend provided for above, or a
reorganization, merger, consolidation, or sale of assets provided for below),
then and in each such event-the holder of each such share of Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock, respectively, shall
have the right thereafter to convert such share into the kind and amount of
shares of stock and other securities and property receivable upon such
reorganization, reclassification, or other change by holders of the number of
shares of Common Stock into which such shares of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock, respectively, might have
been converted immediately prior to such reorganization, reclassification, or
change, all subject to further adjustment as provided herein.

          (i)  Adjustment for Merger or Reorganization, etc.  In case of any
               --------------------------------------------
consolidation or merger of the Corporation with or into another corporation or
the sale or transfer of all or substantially all of the assets of the
Corporation to another corporation, each share of Series A Preferred Stock.
Series B Preferred Stock and Series C Preferred Stock shall thereafter be
convertible into the kind and amount of shares of stock or other securities or
property to which a holder of the number of shares of Common Stock of the
Corporation deliverable upon conversion of such Series A Preferred Stock, Series
B Preferred Stock and Series C Preferred Stock, respectively, would have been
entitled upon such consolidation, merger, sale or transfer; and, in such case,
appropriate adjustment (as determined in good faith by the Board of Directors)
shall be made in the application of the provisions in this Section 4 set forth
with respect to the rights and interest thereafter of the holders of the Series
A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock, to the
end that the provisions set forth In this Section 4 (including provisions with
respect to changes in and other adjustments of the Conversion Price) shall
thereafter be applicable, as nearly as reasonably may be, in relation to any
shares of stock or other property thereafter deliverable upon the conversion of
the Series A Preferred Stock, Series B Preferred Stock or Series C Preferred
Stock, respectively.  Each holder of Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock, upon the occurrence of a merger or
consolidation of the Corporation into or with another corporation (where the
Corporation is not the surviving entity and where the stockholders of the
Corporation fall to hold a majority of the voting securities of the surviving
corporation) or the sale of all or substantially all of the assets of the
Corporation, shall have the option of electing treatment of his shares of Series
A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock under
either this Section 4(1) or Section 2(c) hereof.

                                       58
<PAGE>

          (j)  No Impairment.  The Corporation will not, by amendment of its
               -------------
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation, but will at
all times in good faith assist in the carrying out of all the provisions of this
Section 4 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of the
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
against impairment.

          (k)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Conversion Price pursuant to this Section 4,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each holder of
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
a certificate setting forth such adjustment or readjustment and showing in
detail the facts upon which such adjustment or readjustment is based.  The
Corporation shall, upon the written request at any time of any holder of Series
A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock, furnish
or cause to be furnished to such holder a similar certificate setting forth (i)
such adjustments and readjustments, (ii) the Conversion Price then in effect,
and (iii) the number of shares of Common Stock and the amount, if any, of other
property which then would be received upon the conversion of Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock.

          (l)  Notice of Record Date.  In the event:
               ---------------------

               (i)   that the Corporation declares a dividend (or any other
                     distribution) on its Common Stock, whether in cash,
                     property, stock or other securities;

               (ii)  that the Corporation offers for subscription pro rata to

                     rights;

               (iii) that the Corporation subdivides or combines its outstanding
                     shares of Common Stock;

               (iv) of any reclassification of the Common Stock of the
                    Corporation (other than a subdivision or combination of its
                    outstanding shares of Common Stock or a stock dividend or
                    stock distribution thereon), or of any consolidation or
                    merger of the Corporation into or with another corporation,
                    or of the sale of all or substantially all of the assets of

     5.   Mandatory Conversion.
          --------------------

          (a)  Upon the closing of the sale of shares of Common Stock in a
public offering, underwritten by a nationally recognized underwriter, pursuant
to an effective registration statement under the Securities Act of 1933, as
amended, in which the Corporation, prior to giving effect to the proceeds of the
Offering, is valued at  least $135,000,000 (determined by multiplying the
number of outstanding shares of capital stock of the Corporation on a fully
diluted basis by the initial public offering price) and resulting in at least
$15,000,000 of net proceeds (determined by subtracting underwriters' discounts
and commissions from gross proceeds) to the Corporation (the "Mandatory
Conversion Date"), (i) all outstanding shares of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock shall automatically be
converted into shares of Common Stock, at the then effective conversion rate and
(ii) the number of authorized shares of Preferred Stock shall be automatically
reduced by the number of shares of Preferred Stock that had been designated as
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock,
and all provisions included under the caption "Series A, B and C Convertible
Preferred Stock" and all references to the Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock shall be deleted and shall be of no
further force or effect.

          (b)  All holders of record of shares of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock shall be given written
notice of the Mandatory Conversion Date and the place designated for mandatory
conversion of all such shares of Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock, respectively, pursuant to this Section 5.
Such notice need not be given in advance of the occurrence of the Mandatory
Conversion Date.  An holders of record of shares of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock shall be given written
notice of the filing by the Corporation

                                       60
<PAGE>

of a registration statement under the Securities Act of 1933, as amended, in
connection with which the Corporation is proposing to undertake a public
offering, the closing date of which would be the "Mandatory Conversion Date" as
defined In paragraph (a) above. Such notice shall be given within ten days
following the filing of such registration statement. Any notice required
pursuant to this paragraph (b) shall be sent by first class or registered mail,
postage prepaid, to each record holder of Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock at such holder's address last shown
on the records of the transfer agent for the Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock (or the records of the Corporation,
if it serves as its own transfer agent). Upon receipt of such notice, each
holder of shares of Series A Preferred Stock, Series B Preferred Stock or Series
C Preferred Stock shall surrender his or its certificate or certificates for all
such shares to the Corporation at the place designated in such notice, and shall
thereafter receive certificates for the number of shares of Common Stock to
which such holder is entitled pursuant to this Section 5. On the Mandatory
Conversion Date, all rights with respect to the Series A Preferred Stock, Series
B Preferred Stock and Series C Preferred Stock so converted, including the
rights, if any, to receive notices and vote (other than as a holder of Common
Stock) will terminate, except only the rights of the holders thereof, upon
surrender of their certificate or certificates therefor, to receive certificates
for the number of shares of Common Stock into which such Series A Preferred
Stock, Series B Preferred Stock and Series C Preferred Stock has been converted,
and payment of any declared but unpaid dividends thereon. If so required by the
Corporation, certificates surrendered for conversion shall be endorsed or
accompanied by written instrument or instruments of transfer, in form
satisfactory to the Corporation, duly executed by the registered holder or by
his or its attorney duly authorized in writing. As soon as practicable after the
Mandatory Conversion Date and the surrender of the certificate or certificates
for Series A Preferred Stock, Series B Prefer-red Stock or Series C Preferred
Stock, the Corporation shall cause to be issued and delivered to such holder, or
on his or its written order, a certificate or certificates for the number of
full shares of Common Stock issuable on such conversion in accordance with the
provisions hereof and cash as provided in Subsection 4(b) in respect of any
fraction of a share of Common Stock other-wise issuable upon such conversion.

          (c)  All certificates evidencing shares of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock which are required to be
surrendered for conversion in accordance with the provisions hereof shall, from
and after the Mandatory Conversion Date, be deemed to have been retired and
cancelled and the shares of Series A Preferred Stock, Series B Preferred Stock
and Series C Preferred Stock represented thereby converted into Common Stock for
all purposes, notwithstanding the failure of the holder or holders thereof to
surrender such certificates on or prior to such date.  The Corporation may
thereafter take such appropriate action (without the need for stockholder
action) as may be necessary to reduce the authorized Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock accordingly,

     6.   Mandatory Redemption.
          -----------------------

          (a)  The Corporation will, subject to the conditions set forth in
Subsection 6(b) below, upon the request of any holder of the Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock delivered in writing

                                       61
<PAGE>

below, on June 30, 2000 and on each of the first and second anniversaries
thereof (each such date being referred to hereinafter as a "Mandatory Redemption
Date"), redeem from such holder of shares of Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock, at a price equal to (i) in the
case of Series A Preferred Stock and Series C Preferred Stock, $4.00 per share,
and in the case of Series B Preferred Stock, $6.00 per share, plus accrued
interest at a rate equal to the "prime rate" of Citibank, N.A., as announced
from time to time, plus 2% per annum, plus (ii) any dividends declared but
unpaid thereon, subject to appropriate adjustment in the event of any stock
dividend, stock split, combination or other similar recapitalization affecting
such shares (the "Mandatory Redemption Price"), the following respective
portions of the aggregate number of shares of Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock held by such holder for which
Corporation received cash in payment for the issuance and sale thereof, on the
applicable Mandatory Redemption Date.



                                 Portion of Shares of Series A, B
Redemption Date                and C Preferred Stock To Be Redeemed
- ---------------                ------------------------------------

June 30, 2000                               33%

June 30, 2001              Any shares of Series A, B and C Preferred Stock
                           entitled to be redeemed on the first Mandatory
                           Redemption Date that were not redeemed plus 50% of
                           all remaining shares of Series A, B and C Preferred
                           Stock

June 30, 2002              100% (or all remaining shares of Series A, B and C
                           Preferred Stock)

          (b)  If the funds of the Corporation legally available for redemption
of Series A Preferred Stock, Series B Preferred Stock and Series C Preferred
Stock on any Mandatory Redemption Date are insufficient to redeem the number of
shares of Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock required under this Section 6 to be redeemed on such date, those
funds which are legally available will be used to redeem the maximum possible
number of such shares of Series A Preferred Stock, Series B Preferred Stock and
Series C Preferred Stock ratably on the basis of the number of shares of Series
A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock which
would be redeemed on such date if the funds of the Corporation legally available
therefor had been sufficient to redeem all shares of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock required to be redeemed on
such date.  At any time thereafter when additional funds of the Corporation
become legally available for the redemption of Series A Preferred Stock, Series
B Preferred Stock and Series C Preferred Stock, such funds will be used, at the
end of the next succeeding fiscal quarter, to redeem the balance of the shares
which the Corporation was theretofore obligated to redeem, or such portion
thereof for which funds are available, ratably on the basis set forth in the
preceding sentence.

          (c)  The holder of Series A Preferred Stock, Series B Preferred Stock
or Series C Preferred Stock requesting redemption shall provide notice of any
redemption of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock pursuant to this Section 6, by registered mail, postage prepaid,
to the Corporation not less than six (6) months prior to the

                                       62
<PAGE>

date on which such redemption is to be made. The notice will specify the number
of shares which are to be redeemed. Upon receipt of any such notice of
redemption, the Corporation will become obligated to redeem on the applicable
Mandatory Redemption Date all Series A Preferred Stock, Series B Preferred Stock
and Series C Preferred Stock specified therein (other than such shares of Series
A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock as are
duly converted pursuant to Section 4 prior to the close of business on the fifth
full day preceding the Mandatory Redemption Date). In case less than all Series
A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock
represented by any certificate is redeemed in any redemption pursuant to this
Section 6, a new certificate will be issued representing the unredeemed Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock without
cost to the holder thereof.

          (d)  Unless there shall have been a default in payment of the
Mandatory Redemption Price, no share of Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock that is redeemed shall be entitled
to any dividends declared after is Mandatory Redemption Date, and on such
Mandatory Redemption Date all rights of the holder of such shares as a
stockholder of the Corporation by reason of the ownership of such share will
cease, except the right to receive the Mandatory Redemption Price of such share,
without interest, upon presentation and surrender of the certificate
representing such share, and such share will not from and after such Mandatory
Redemption Date be deemed to be outstanding.

          (e)  Any Series A Preferred Stock, Series B Preferred Stock or Series
C Preferred Stock redeemed pursuant to this Section 6 will be cancelled and will
not under any circumstances be reissued, sold or transferred and the Corporation
may from time to time take such appropriate action as may be necessary to reduce
the authorized Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock accordingly.

provisions of Section 242(b)(2) of the General Corporation Law of Delaware.

     4.   Optional Conversion.  The holders of the Series A Preferred Stock,
          -------------------
Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock
shall have conversion rights as follows (the "Conversion Rights"):

          (a)  Right to Convert.  Each share of Series A Preferred Stock, Series
               ----------------
B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock shall
be convertible, at the option of the holder thereof, at any time and from time
to time, and without the payment of additional consideration by the holder
thereof, into such number of fully paid and nonassessable shares of Common Stock
as is determined by dividing, in the case of the Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock, $4.00, and in the case of
a share of the Series D Preferred Stock, the applicable Series D Issuance Price,
by the applicable Conversion Price (as defined below) in effect at the time of
conversion.  The "Conversion Price" shall initially be $4.00 in the case of the
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock,
and in the case of a share of the Series D Preferred Stock, by the applicable
Series D Issuance Price.  Such applicable initial Conversion Price, and the rate
at which shares of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock may be converted into shares of
Common Stock, shall be subject to adjustment as provided below.

     In the event of a notice of redemption of any shares of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred
Stock pursuant to Section 6 hereof, the Conversion Rights of the shares of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or
Series D Preferred Stock, respectively, designated for redemption shall
terminate at the close of business on the fifth full day preceding the date
fixed for redemption, unless the redemption price is not paid when due, in which
case the Conversion Rights of Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock or Series D Preferred Stock for such shares
shall continue until such price is paid in full.  In the event of a liquidation
of the Corporation, the Conversion Rights shall terminate at the close of
business on the first full day preceding the date fixed for the payment of any
amounts distributable on liquidation to the holders of Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock,
respectively.

          (b)  Fractional Shares.  No fractional shares of Common Stock shall be
               -----------------
issued upon conversion of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock or Series D Preferred Stock.  In lieu of any
fractional shares to which the holder would otherwise be entitled, the
Corporation shall pay cash equal to such fraction multiplied by the then
effective Conversion Price.

          (c)  Mechanics of Conversion.
               -----------------------

               (i)  In order for a holder of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D Preferred Stock to convert
shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock or Series D Preferred

                                       69
<PAGE>

Stock into shares of Common Stock, such holder shall surrender the certificate
or certificates for such shares of Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock or Series D Preferred Stock, at the office of
the transfer agent for the Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock or Series D Preferred Stock, respectively (or at the
principal office of the Corporation if the Corporation serves as its own
transfer agent), together with written notice that such holder elects to convert
all or any number of the shares of the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D Preferred Stock
represented by such certificate or certificates. Such notice shall state such
holder's name or the names of the nominees in which such holder wishes the
certificate or certificates for shares of Common Stock to be issued. If required
by the Corporation, certificates surrendered for conversion shall be endorsed or
accompanied by a written instrument or instruments of transfer, in form
satisfactory to the Corporation, duly executed by the registered holder or his
or its attorney duly authorized in writing. The date of receipt of such
certificates and notice by the transfer agent (or by the Corporation if the
Corporation serves as its own transfer agent) shall be the conversion date
("Conversion Date") and such holder shall be treated as a record holder of
Common Stock on such date. The Corporation shall, as soon as practicable after
the Conversion Date, issue and deliver at such office to such holder of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock, or to his or its nominees, a certificate or certificates for
the number of shares of Common Stock to which such holder shall be entitled,
together with cash in lieu of any fraction of a share, and a certificate or
certificates for the number of shares of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D Preferred Stock
represented by the surrendered certificate but not converted.

          (ii)   The Corporation shall at all times when the Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred
Stock shall be outstanding, reserve and keep available out of its authorized but
unissued stock, for the purpose of effecting the conversion of the Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock, such number of its duly authorized shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock or Series D Preferred Stock. Before taking any action which
would cause an adjustment reducing the Conversion Price below the then par value
of the shares of Common Stock issuable upon conversion of the Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred
Stock, the Corporation will take any corporate action which may, in the opinion
of its counsel, be necessary in order that the Corporation may validly and
legally issue fully paid and nonassessable shares of Common Stock at such
adjusted Conversion Price.

          (iii)  Upon any such conversion, adjustment to the Conversion Price
of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock
or Series D Preferred Stock, shall be made for any declared but unpaid dividends
on the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock or Series D Preferred Stock, respectively, surrendered for conversion or
on the Common Stock delivered upon conversion.

          (iv)   All shares of Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock and Series D Preferred Stock which shall have
been surrendered for conversion as herein provided shall no longer be deemed to
be outstanding and all rights with

                                       70
<PAGE>

respect to such shares, including the rights, if any, to receive notices and to
vote, shall immediately cease and terminate on the Conversion Date, except only
the right of the holders thereof to receive shares of Common Stock in exchange
therefor and payment of any dividends declared but unpaid thereon. Any shares of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or
Series D Preferred Stock so converted shall be retired and cancelled and shall
not be reissued, and the Corporation (without the need for stockholder action)
may from time to time take such appropriate action as may be necessary to reduce
the authorized Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock accordingly.

               (v)  The Corporation shall pay any and all issue and other taxes
that may be payable in respect of any issuance or delivery of shares of Common
Stock upon conversion of shares of Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock or Series D Preferred Stock pursuant to this
Section 4. The Corporation shall not, however, be required to pay any tax which
may be payable in respect of any transfer involved in the issuance and delivery
of shares of Common Stock in a name other than that in which the shares of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or
Series D Preferred Stock so converted were registered, and to the extent the
Company would be required to pay such a tax, no such issuance or delivery shall
be made unless and until the person or entity requesting such issuance has paid
to the Corporation the amount of any such tax or has established, to the
satisfaction of the Corporation, that such tax has been paid.

          (d)  Adjustments to Conversion Price for Diluting Issues:
               ---------------------------------------------------

               (i)  Special Definitions.  For purposes of this Subsection 4(d),
                    -------------------
the following definitions shall apply:

                    (A)  "Option" shall mean rights, options or warrants to
                          ------
subscribe for, purchase or otherwise acquire Common Stock or Convertible
Securities, excluding options described in subsection 4(d)(i)(D)(IV) below.

                    (B)  "Original Issue Date" shall mean the date on which a
                          -------------------
share of Series A Preferred Stock was first issued.

                    (C)  "Convertible Securities" shall mean any evidences of
                          ----------------------
indebtedness, shares or other securities directly or indirectly convertible into
or exchangeable for Common Stock.

                    (D)  "Additional Shares of Common Stock" shall mean all
                          ---------------------------------
shares of Common Stock issued (or, pursuant to Subsection 4(d)(iii) below,
deemed to be issued) by the Corporation after the Original Issue Date, other
than shares of Common Stock issued or issuable:

                         (I)  upon conversion of any Convertible Securities
                              outstanding on the Original Issue Date, or upon
                              exercise of any Options outstanding on the
                              Original Issue Date;

                                       71
<PAGE>

                         (II)  as a dividend or distribution on Series A
                               Preferred Stock, Series B Preferred Stock, Series
                               C Preferred Stock or Series D Preferred Stock;

                         (III) by reason of a dividend, stock split, split-up or
                               other distribution on shares of Common Stock that
                               is covered by Subsection 4(e) or 4(f) below; or

                         (IV)  to employees, officers or directors of, or
                               consultants or advisors to, the Corporation
                               pursuant to a plan adopted by the Board of
                               Directors of the Corporation (which, together
                               with all other such plans, provides for the
                               issuance of no more than an aggregate of
                               1,500,000 shares of Common Stock (subject to
                               appropriate adjustment in the event of any stock
                               dividend, stock split, combination or other
                               similar recapitalization affecting the Common
                               Stock)).

          (ii)  No Adjustment of Conversion Price.  No adjustment in the number
                ---------------------------------
of shares of Common Stock into which the Series A Preferred Stock.  Series B
Preferred Stock, Series C Preferred Stock or Series D Preferred Stock is
convertible shall be made, by adjustment in the applicable Conversion Price
thereof, unless the consideration per share (determined pursuant to Subsection
4(d)(v)) for an Additional Share of Common Stock issued or deemed to be issued
by the Corporation is less than the applicable Conversion Price in effect on the
date of, and immediately prior to, the issue of such Additional Shares.

          (iii) Issue of Securities Deemed Issue of Additional Shares
                -----------------------------------------------------
                of Common Stock.
                ---------------

     If the Corporation at any time or from time to time after the Original
Issue Date shall any Options or Convertible Securities or shall fix a record
date for the determination of holders of any class of securities entitled to
receive any such Options or Convertible Securities, then the maximum number of
shares of Common Stock (as set forth in the instrument relating thereto without
regard to any provision contained therein for a subsequent adjustment of such
number) issuable upon the exercise of such Options or, in the case of
Convertible Securities and Options therefor, the conversion or exchange of such
Convertible Securities, shall be deemed to be Additional Shares of Common Stock
issued as of the time of such issue or, in case such a record date shall have
been fixed, as of the close of business on such record date, provided that
Additional Shares of Common Stock shall not be deemed to have been issued unless
the consideration per share (determined pursuant to Subsection 4(d)(v) hereof)
of such Additional Shares of Common Stock would be less than the applicable
Conversion Price in effect on the date of and immediately prior to such issue,
or such record date, as the case may be, and provided further than in any such
case in which Additional Shares of Common Stock are deemed to be issued:

                                       72
<PAGE>

               (A)  No further adjustment in the Conversion Price shall be made
upon the subsequent issue of Convertible Securities or shares of Common Stock
upon the exercise of such Options or conversion or exchange of such Convertible
Securities;

               (B)  If such Options or Convertible Securities by their terms
provide, with the passage of time or otherwise, for any increase in the
consideration payable to the Corporation, upon the exercise, conversion or
exchange thereof, the Conversion Price computed upon the original issue thereof
(or upon the occurrence of a record date with respect thereto), and any
subsequent adjustments based thereon, shall, upon any such increase becoming
effective, be recomputed to reflect such increase insofar as it affects such
Options or the rights of conversion or exchange under such Convertible
Securities;

               (C)  Upon the expiration or termination of any unexercised
Option, the Conversion Price shall be readjusted, and the Additional Shares of
Common Stock deemed issued as the result of the original issue of such Option
shall not be deemed issued for the purposes of any subsequent adjustment of the
Conversion Price;

               (D)  In the event of any change in the number of shares of Common
Stock issuable upon the exercise, conversion or exchange of any Option or
Convertible Security, including, but not limited to, a change resulting from the
anti-dilution provisions thereof, the Conversion Price then in effect shall
forthwith be readjusted to such Conversion Price as would have obtained had the
adjustment which was made upon the issuance of such Option or Convertible
Security prior to such change been made upon the basis of such change; and

               (E)  No readjustment pursuant to clause (B), (C) or (D) above
shall have the effect of increasing the Conversion Price to an amount which
exceeds the lower of (i) the Conversion Price on the original adjustment date,
or (ii) the Conversion Price that would have resulted from any issuances of
Additional Shares of Common Stock between the original adjustment date and such
readjustment date.

     In the event the Corporation, after the Original Issue Date, amends the
terms of any Options or Convertible Securities (whether such Options or
Convertible Securities were outstanding on the Original Issue Date or were
issued after the Original Issue Date), then such Options or Convertible
Securities, as so amended, shall be deemed to have been issued after the
Original Issue Date and the provisions of this Subsection 4(d)(iii) shall apply.

          (iv) Adjustment of Conversion Price Upon Issuance of
               ------------------------------------------------
               Additional Shares of Common Stock.
               ---------------------------------

     In the event the Corporation shall at any time after the Original Issue
Date issue Additional Shares of Common Stock (including Additional Shares of
Common Stock deemed to be issued pursuant to Subsection 4(d)(iii), but excluding
shares issued as a stock split or combination as provided in Subsection 4(e) or
upon a dividend or distribution as provided in Subsection 4(f), without
consideration or for a consideration per share less than the applicable
Conversion Price in effect on the date of and immediately prior to such
issuance, then and in such event, such Conversion Price shall be reduced,
concurrently with such issue, to a price

                                       73
<PAGE>

(calculated to the nearest cent) determined by multiplying such Conversion Price
by a fraction, (A) the numerator of which shall be (1) the number of shares of
Common Stock outstanding immediately prior to such issue plus (2) the number of
shares of Common Stock which the aggregate consideration received or to be
received by the Corporation for the total number of Additional Shares of Common
Stock so issued would purchase at such Conversion Price; and (B) the denominator
of which shall be the number of shares of Common Stock outstanding immediately
prior to such issue plus the number of such Additional Shares of Common Stock so
issued; provided that (i) for the purpose of this Subsection 4(d)(iv), all
        -------- ----
shares of Common Stock issuable upon exercise or conversion of Options
(including the conversion into Common Stock of Convertible Securities issuable
upon the exercise of such Options) or Convertible Securities outstanding
immediately prior to such issue shall be deemed to be outstanding, (ii) the
number of shares of Common Stock deemed issuable upon exercise or conversion of
such outstanding Options and Convertible Securities shall not give effect to any
adjustments to the conversion price or conversion rate of such Options or
Convertible Securities resulting from the issuance of Additional Shares of
Common Stock that is the subject of this calculation, and (iii) immediately
after any Additional Shares of Common Stock are deemed issued pursuant to
Section 4(d)(iii), such Additional Shares of Common Stock shall be deemed to be
outstanding.

               (v)  Determination of Consideration. For purposes of this
                    ------------------------------
Subsection 4(d), the consideration received by the Corporation for the issue of
any Additional Shares of Common Stock shall be computed as follows:

                    (A)  Cash and Property.  Such consideration shall:
                         -----------------

                         (I)   insofar as it consists of cash, be computed at
the aggregate amount of cash received by the Corporation, excluding amounts paid
or payable for accrued interest or accrued dividends;

                         (II)  insofar as it consists of property other than
cash, be computed at the fair market value thereof at the time of such issue, as
determined in good faith by the Board of Directors, and

                         (III) in the event Additional Shares of Common Stock
are issued together with other shares or securities or other assets of the
Corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (I) and (II) above,
as determined in good faith by the Board of Directors.

                    (B)  Options and Convertible Securities. The consideration
                         ----------------------------------
per share received by the Corporation for Additional Shares of Common Stock
deemed to have been issued pursuant to Subsection 4(d)(iii), relating to Options
and Convertible Securities, shall be determined by dividing

                         (x)  the total amount, if any, received or receivable
by the Corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration) payable to
the Corporation upon the exercise of such Options or the conversion or

                                       74
<PAGE>

exchange of such Convertible Securities, or in the case of Options for
Convertible Securities, the exercise of such Options for Convertible Securities
and the conversion or exchange of such Convertible Securities, by

                    (y)  the maximum number or shares of Common Stock (as set
forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

               (vi) Multiple Closing Dates. In the event the Corporation shall
                    ----------------------
issue on more than one date Additional Shares of Common Stock which are
comprised of shares of the same series or class of Preferred Stock, and such
issuance dates occur within a period of no more than 120 days, then the
Conversion Price shall be adjusted only once on account of such issuances, with
such adjustment to occur upon the final such issuance and to give effect to all
such issuances as if they occurred on the date of the final such issuance.

          (e)  Adjustment for Stock Splits and Combinations.  If the Corporation
               --------------------------------------------
shall at any time or from time to time after the Original Issue Date effect a
subdivision of the outstanding Common Stock into a greater number of shares of
Common Stock (by reclassification or otherwise than by payment of a dividend in
Common Stock), the Conversion Price then in effect immediately before that
subdivision shall be proportionately decreased. If the Corporation shall at any
time or from time to time after the Original Issue Date combine the outstanding
shares of Common Stock into a lesser number of shares of Common Stock, the
Conversion Price then in effect immediately before the combination shall be
proportionately increased. Any adjustment under this paragraph shall become
effective at the close of business on the date the subdivision or combination
becomes effective.

          (f)  Adjustment for Certain Dividends and Distributions.  In the event
               --------------------------------------------------
the Corporation at any time, or from time to time after the Original Issue Date
shall make or issue, or from 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, then and in each such event the Conversion
Price for the Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock then in effect shall be decreased
as of the time of such issuance or, in the event such a record date shall have
been fixed, as of the close of business on such record date, by multiplying the
Conversion Price for the Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock or Series D Preferred Stock, as applicable, then in
effect by a fraction:

          (1)  the numerator of which shall be 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

          (2)  the denominator of which shall be 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:

                                       75
<PAGE>

provided, however, if such record date shall have been fixed and such dividend
is not fully paid or if such distribution is not fully made on the date fixed
therefor, the Conversion Price for the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock shall be
recomputed accordingly as of the close of business on such record date and
thereafter the Conversion Price for the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock shall be
adjusted pursuant to this paragraph as of the time of actual payment of such
dividends or distributions; and provided further, however, that no such
adjustment shall be made to Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock or Series D Preferred Stock if the holders of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock, respectively, simultaneously receive a dividend or other
distribution of shares of Common Stock in a number equal to the number of shares
of Common Stock as they would have received if all outstanding shares of Series
A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series
D Preferred Stock, respectively, had been converted into Common Stock on the
date of such event.

          (g) Adjustments for Other Dividends and Distributions.  In the event
              -------------------------------------------------
the Corporation at any time or from time to time after the Original Issue Date
for the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock or Series D Preferred Stock shall make or issue, or fix a record date for
the determination of holders of Common Stock entitled to receive, a dividend or
other distribution payable in securities of the Corporation other than shares of
Common Stock, then and in each such event provision shall be made so that the
holders of the Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock or Series D Preferred Stock, respectively, shall receive upon
conversion thereof in addition to the number of shares of Common Stock
receivable thereupon, the amount of securities of the Corporation that they
would have received had the Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock or Series D Preferred Stock, respectively, 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, giving application to all adjustments called for during such period
under this paragraph with respect to the rights of the holders of the Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock; and provided further, however, that no such adjustment to the
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or
Series D Preferred Stock shall be made if the holders of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred
Stock, respectively, simultaneously receive a dividend or other distribution of
such securities in an amount equal to the amount of such securities as they
would have received if all outstanding shares of Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock,
respectively, had been converted into Common Stock on the date of such event.

          (h) Adjustment for Reclassification, Exchange or Substitution.  If the
              ---------------------------------------------------------
Common Stock issuable upon conversion of the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D Preferred Stock shall be
changed into the same or a different number of shares of any class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares or stock dividend provided for
above, or a reorganization, merger, consolidation, or sale of assets

                                       76
<PAGE>

provided for below), then and in each such event the holder of each such share
of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock
or Series D Preferred Stock, respectively, shall have the right thereafter to
convert such share into the kind and amount of shares of stock and other
securities and property receivable upon such reorganization, reclassification,
or other change by holders of the number of shares of Common Stock into which
such shares of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock or Series D Preferred Stock, respectively, might have been
converted immediately prior to such reorganization, reclassification, or change,
all subject to further adjustment as provided herein.

          (i) Adjustment for Merger or Reorganization, etc.  In case of any

3.   Mandatory Conversion.
     --------------------

     3.1  Upon the Termination Date, the outstanding share of Series E Preferred
          Stock shall automatically be converted into one share of Common Stock.

     3.2  Upon the Termination Date, the holder of the share of Series E
          Preferred Stock shall surrender its certificate for such share to the
          Corporation, and shall thereafter receive a certificate for the one
          share of Common Stock to which such holder is entitled pursuant to
          Section 3.1.  On the Termination Date, the outstanding share of Series
          E Preferred Stock shall be deemed to have been converted into one
          share of Common Stock, which shall be deemed to be outstanding of
          record, and all rights with respect to the Series E Preferred Stock so
          converted, including the rights, if any, to receive notices and vote
          (other than as a holder of Common Stock) will terminate, except only
          the rights of the holders thereof, upon surrender of its certificate
          therefor, to receive a certificate for the one share of Common




          Stock into which such Series E Preferred Stock has been converted. The
          certificate surrendered for conversion shall be endorsed or
          accompanied by written instrument or instruments of transfer, in form
          satisfactory to the Corporation, duly executed by the registered
          holder or by its attorney duly authorized in writing. As soon as
          practicable after the Termination Date and the surrender of the
          certificate for Series E Preferred Stock, the Corporation shall cause
          to be issued and delivered to such holder a certificate for the one
          share of Common Stock issuable on such conversion in accordance with
          the provisions hereof.

     3.3  The certificate evidencing the share of Series E Preferred Stock which
          is required to be surrendered for conversion in accordance with the
          provisions of this Section 3 shall, from and after the Termination
          Date, be deemed to have been retired and cancelled and the share of
          Series E Preferred Stock represented thereby converted into Common
          Stock for all purposes, notwithstanding the failure of the holder
          thereof to surrender such certificate on or prior to such date.  Such
          converted Series E Preferred Stock may not be reissued, and the
          Corporation may thereafter take such appropriate action (without the
          need for stockholder action) as may be necessary to reduce the
          authorized number of shares of Series E Preferred Stock accordingly.

     4.   Optional Conversion.  At the written request of the holder of the
          -------------------
          outstanding share of Series E Preferred Stock at any time, the
          outstanding share of Series E Preferred Stock may be converted into
          one share of Common Stock.

IN WITNESS WHEREOF, the Corporation has caused this Certificate of Designations
to be signed by its President this day of June 28, 1999.

as amended.

     1.   Number of Directors; Election of Directors.  The number of directors
          ------------------------------------------
of the Corporation shall not be less than three.  The exact number of directors
within the limitations specified in the preceding sentence shall be determined
from time to time by, or in the manner provided in, the By-laws of the
Corporation.  Election of directors need not be by written ballot, except as and
to the extent provided in the By-laws of the Corporation.

     2.   Classes of Directors.  Except for any directors entitled to be elected
          --------------------
by the holders of preferred stock or any other securities of the Corporation
(other than common stock), the Board of Directors shall be and is divided into
three classes:  Class I, Class II and Class III.  No one class shall have more
than one director more than any other class.  If a fraction is contained in the
quotient arrived at by dividing the authorized number of directors by three,

                           -------- -------
shall continue until the election and qualification of his successor and be
subject to his earlier death, resignation or removal.

     4.   Allocation of Directors Among Classes in the Event of Increases or
          ------------------------------------------------------------------
Decreases in the Authorized Number of Directors.  In the event of any increase

serving as such shall nevertheless continue as a director of the class of which
he is a member until the expiration of his current term, subject to his earlier
death, resignation or removal and (ii) the newly created or eliminated
directorships resulting from such increase or decrease shall be apportioned by
the Board of Directors among the three classes of directors in accordance with
the provisions of Section 2 of this Article ELEVENTH.  To the extent possible,
consistent with the provisions of Section 2 of this Article ELEVENTH, any newly
created directorships shall be added to those classes whose terms of office are

offices are to expire at the earliest dates following such allocation, unless
otherwise provided from time to time by resolution of the Board of Directors.

directors present may adjourn the meeting from time to time without further
notice other than announcement at the meeting, until a quorum shall be present.

     6.   Action at Meeting.  Every act or decision done or made by a majority
          -----------------
of the directors present at a meeting duly held at which a quorum is present
shall be regarded as the act of the Board of Directors unless a greater number
is required by law, by this Certificate of Incorporation, or by the By-laws of
the Corporation.

     7.   Removal.  Prior to July 2, 2001 (or if earlier the date that the

Incorporation.

shall be elected to hold office until the next election of the class for which
such director shall have been chosen, subject to the election and qualification
of his successor and to his earlier death, resignation or removal.

          If:                                                  Then, the Number of Directors is:

                                                               however; that in no event shall the number be (i) less than one at

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

             3.1  Upon the Termination Date, the outstanding share of Series E
                  Preferred Stock shall automatically be converted into one
                  share of Common Stock.

             3.2  Upon the Termination Date, the holder of the share of Series E
                  Preferred Stock shall surrender its certificate for such share
                  to the Corporation, and shall thereafter receive a certificate
                  for the one share of Common Stock to which such holder is
                  entitled pursuant to Section 3.1. On the Termination Date, the
                  outstanding share of Series E Preferred Stock shall be deemed
                  to have been converted into one share of Common Stock, which
                  shall be deemed to be outstanding of record, and all rights
                  with respect to the Series E Preferred Stock so converted,
                  including the rights, if any, to receive notices and vote
                  (other than as a holder of Common Stock) will terminate,
                  except only the rights of the holders thereof, upon surrender
                  of its certificate therefor, to receive a certificate for the
                  one share of Common Stock into which such Series E Preferred
                  Stock has been converted. The certificate surrendered for
                  conversion shall be endorsed or accompanied by written
                  instrument or instruments of transfer, in form satisfactory to
                  the Corporation, duly executed by the registered holder or by
                  its attorney duly authorized in writing. As soon as
                  practicable after the Termination Date and the surrender of
                  the certificate for Series E Preferred Stock, the Corporation
                  shall cause to be issued and delivered to such holder a
                  certificate for the one share of Common Stock issuable on such
                  conversion in accordance with the provisions hereof.

             3.3  The certificate evidencing the share of Series E Preferred
                  Stock which is required to be surrendered for conversion in
                  accordance with the provisions of this Section 3 shall, from
                  and after the Termination Date, be deemed to have been retired
                  and cancelled and the share of Series E Preferred Stock
                  represented thereby converted into Common Stock for all
                  purposes, notwithstanding the failure of the holder thereof to
                  surrender such certificate on or prior to such date. Such
                  converted Series E Preferred Stock may not be reissued, and
                  the Corporation may thereafter take such appropriate action
                  (without the need for stockholder action) as may be necessary
                  to reduce the authorized number of shares of Series E
                  Preferred Stock accordingly.

     4.  Optional Conversion.  At the written request of the holder of the
         -------------------
outstanding share of Series E Preferred Stock at any time, the outstanding share
of Series E Preferred Stock may be converted into one share of Common Stock.

     FIFTH.  Except as otherwise provided herein, the Corporation reserves the
right to amend, alter, change or repeal any provision contained in this
Certificate of Incorporation, in the manner now or hereafter prescribed by
statute and this Certificate of Incorporation, and all rights conferred upon
stockholders herein are granted subject to this reservation.

                                      -6-
<PAGE>

     SIXTH.  In furtherance and not in limitation of the powers conferred upon
it by the laws of the State of Delaware, the Board of Directors shall have the
power to adopt, amend, alter or repeal the Corporation's By-laws.  The
affirmative vote of a majority of the directors present at any regular or
special meeting of the Board of Directors at which a quorum is present shall be
required to adopt, amend, alter or repeal the Corporation's By-laws.  The
Corporation's By-laws also may be adopted, amended, altered or repealed by the
affirmative vote of the holders of at least seventy-five percent (75%) of the
votes which all the stockholders would be entitled to cast in any annual
election of directors or class of directors.  Notwithstanding any other
provisions of law, this Certificate of Incorporation or the By-Laws of the
Corporation, and notwithstanding the fact that a lesser percentage may be
specified by law, the affirmative vote of the holders of at least seventy-five
percent (75%) of the votes which all the stockholders would be entitled to cast
in any annual election of directors or class of directors shall be required to
amend or repeal, or to adopt any provision inconsistent with, this Article
SIXTH.

     SEVENTH.  Except to the extent that the General Corporation Law of Delaware
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty, no director of the Corporation shall be personally liable to
the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, notwithstanding any provision of law imposing such
liability.  No amendment to or repeal of this provision shall apply to or have
any effect on the liability or alleged liability of any director of the
Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment or repeal.

     EIGHTH.  1.  Actions, Suits and Proceedings Other than by or in the Right
                  ------------------------------------------------------------
of the Corporation.  The Corporation shall indemnify each 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 (other than an action by or in the right of the Corporation), by
reason of the fact that he is or was, or has agreed to become, a director or
officer of the Corporation, or is or was serving, or has agreed to serve, at the
request of the Corporation, as a director, officer, partner, employee or trustee
of, or in a similar capacity with, another corporation, partnership, joint
venture, trust or other enterprise (including any employee benefit plan) (all
such persons being referred to hereafter as an "Indemnitee"), or by reason of
any action alleged to have been taken or omitted in such capacity, against all
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him or on his behalf in
connection with such action, suit or proceeding and any appeal therefrom, if he
acted in good faith and in a manner he 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 conduct
was unlawful.  The termination of any action, suit or proceeding by judgment,
order, settlement, conviction or upon a plea of nolo contendere or its
                                                ---------------
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he 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 reasonable cause to believe that his conduct
was unlawful.

     2.  Actions or Suits by or in the Right of the Corporation.  The
         ------------------------------------------------------
Corporation shall indemnify any Indemnitee who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason of the fact that he is or was, or has agreed to become, a director

                                      -7-
<PAGE>

or officer of the Corporation, or is or was serving, or has agreed to serve, at
the request of the Corporation, as a director, officer, partner, employee or
trustee of, or in a similar capacity with, another corporation, partnership,
joint venture, trust or other enterprise (including any employee benefit plan),
or by reason of any action alleged to have been taken or omitted in such
capacity, against all expenses (including attorneys' fees) and, to the extent
permitted by law, amounts paid in settlement actually and reasonably incurred by
him or on his behalf in connection with such action, suit or proceeding and any
appeal therefrom, if he acted in good faith and in a manner he reasonably
believed to be in, or not opposed to, the best interests of the Corporation,
except that no indemnification shall be made in respect of any claim, issue or
matter as to which such person shall have been adjudged to be liable to the
Corporation unless and only to the extent that the Court of Chancery of Delaware
shall determine upon application that, despite the adjudication of such
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses (including
attorneys' fees) which the Court of Chancery of Delaware shall deem proper.

     3.  Indemnification for Expenses of Successful Party.  Notwithstanding the
         ------------------------------------------------
other provisions of this Article, to the extent that an Indemnitee has been
successful, on the merits or otherwise, in defense of any action, suit or
proceeding referred to in Sections 1 and 2 of this Article EIGHTH, or in defense
of any claim, issue or matter therein, or on appeal from any such action, suit
or proceeding, he shall be indemnified against all expenses (including
attorneys' fees) actually and reasonably incurred by him or on his behalf in
connection therewith.  Without limiting the foregoing, if any action, suit or
proceeding is disposed of, on the merits or otherwise (including a disposition
without prejudice), without (i) the disposition being adverse to the Indemnitee,
(ii) an adjudication that the Indemnitee was liable to the Corporation, (iii) a
plea of guilty or nolo contendere by the Indemnitee, (iv) an adjudication that
                  ---------------
the Indemnitee did not act in good faith and in a manner he reasonably believed
to be in or not opposed to the best interests of the Corporation, and (v) with
respect to any criminal proceeding, an adjudication that the Indemnitee had
reasonable cause to believe his conduct was unlawful, the Indemnitee shall be
considered for the purposes hereof to have been wholly successful with respect
thereto.

     4.  Notification and Defense of Claim.  As a condition precedent to his
         ---------------------------------
right to be indemnified, the Indemnitee must notify the Corporation in writing
as soon as practicable of any action, suit, proceeding or investigation
involving him for which indemnity will or could be sought.  With respect to any
action, suit, proceeding or investigation of which the Corporation is so
notified, the Corporation will be entitled to participate therein at its own
expense and/or to assume the defense thereof at its own expense, with legal
counsel reasonably acceptable to the Indemnitee.  After notice from the
Corporation to the Indemnitee of its election so to assume such defense, the
Corporation shall not be liable to the Indemnitee for any legal or other
expenses subsequently incurred by the Indemnitee in connection with such action,
suit, proceeding or investigation, other than as provided below in this Section
4.  The Indemnitee shall have the right to employ his own counsel in connection
with such action, suit, proceeding or investigation, but the fees and expenses
of such counsel incurred after notice from the Corporation of its assumption of
the defense thereof shall be at the expense of the Indemnitee unless (i) the
employment of counsel by the Indemnitee has been authorized by the Corporation,
(ii) counsel to the Indemnitee shall have reasonably concluded that there may be
a conflict of interest or position on any significant issue between the
Corporation and the Indemnitee in the conduct of the defense of such action,
suit, proceeding or investigation or (iii) the Corporation

                                      -8-
<PAGE>

shall not in fact have employed counsel to assume the defense of such action,
suit, proceeding or investigation, in each of which cases the fees and expenses
of counsel for the Indemnitee shall be at the expense of the Corporation, except
as otherwise expressly provided by this Article. The Corporation shall not be
entitled, without the consent of the Indemnitee, to assume the defense of any
claim brought by or in the right of the Corporation or as to which counsel for
the Indemnitee shall have reasonably made the conclusion provided for in clause
(ii) above. The Corporation shall not be required to indemnify the Indemnitee
under this Article for any amounts paid in settlement of any action, suit,
proceeding or investigation effected without its written consent. The
Corporation shall not settle any action, suit, proceeding or investigation in
any manner which would impose any penalty or limitation on the Indemnitee
without the Indemnitee's written consent. Neither the Corporation nor the
Indemnitee will unreasonably withhold or delay its consent to any proposed
settlement.

     5.  Advance of Expenses.  Subject to the provisions of Section 6 of this
         -------------------
Article EIGHTH, in the event that the Corporation does not assume the defense
pursuant to Section 4 of this Article EIGHTH of any action, suit, proceeding or
investigation of which the Corporation receives notice under this Article, any
expenses (including attorneys' fees) incurred by an Indemnitee in defending a
civil or criminal action, suit, proceeding or investigation or any appeal
therefrom shall be paid by the Corporation in advance of the final disposition
of such matter; provided, however, that the payment of such expenses incurred by
                --------  -------
the Indemnitee in advance of the final disposition of such matter shall be made
only upon receipt of an undertaking by or on behalf of the Indemnitee to repay
all amounts so advanced in the event that it shall ultimately be determined that
the Indemnitee is not entitled to be indemnified by the Corporation as
authorized in this Article; and further provided that no such advancement of
                                ------- --------
expenses shall be made if it is determined (in the manner described in Section
6) that (i) the Indemnitee did not act in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
Corporation, or (ii) with respect to any criminal action or proceeding, the
Indemnitee had reasonable cause to believe his conduct was unlawful.  Such
undertaking shall be accepted without reference to the financial ability of the
Indemnitee to make such repayment.

     6.  Procedure for Indemnification.  In order to obtain indemnification or
         -----------------------------
advancement of expenses pursuant to Section 1, 2, 3 or 5 of this Article EIGHTH,
the Indemnitee shall submit to the Corporation a written request, including in
such request such documentation and information as is reasonably available to
the Indemnitee and is reasonably necessary to determine whether and to what
extent the Indemnitee is entitled to indemnification or advancement of expenses.
Any such indemnification or advancement of expenses shall be made promptly, and
in any event within 60 days after receipt by the Corporation of the written
request of the Indemnitee, unless with respect to requests under Section 1, 2 or
5 of this Article EIGHTH the Corporation determines within such 60-day period
that the Indemnitee did not meet the applicable standard of conduct set forth in
Section 1, 2 or 5 of this Article EIGHTH, as the case may be.  Such
determination shall be made in each instance (a) by a majority vote of the
directors of the Corporation consisting of persons who are not at that time
parties to the action, suit or proceeding in question ("disinterested
directors"), whether or not a quorum, (b) by a majority vote of a committee of
disinterested directors designated by majority vote of disinterested directors,
whether or not a quorum, (c) if there are no disinterested directors, or if
disinterested directors so direct, by independent legal counsel (who may, to the
extent permitted

                                      -9-
<PAGE>

by law, be regular legal counsel to the Corporation) in a written opinion, or
(d) by the stockholders of the Corporation.

     7.  Remedies.  The right to indemnification or advances as granted by this
         --------
Article shall be enforceable by the Indemnitee in any court of competent
jurisdiction if the Corporation denies such request, in whole or in part, or if
no disposition thereof is made within the 60-day period referred to above in
Section 6.  Unless otherwise required by law, the burden of proving that the
Indemnitee is not entitled to indemnification or advancement of expenses under
this Article shall be on the Corporation.  Neither the failure of the
Corporation to have made a determination prior to the commencement of such
action that indemnification is proper in the circumstances because the
Indemnitee has met the applicable standard of conduct, nor an actual
determination by the Corporation pursuant to Section 6 of this Article EIGHTH
that the Indemnitee has not met such applicable standard of conduct, shall be a
defense to the action or create a presumption that the Indemnitee has not met
the applicable standard of conduct.  The Indemnitee's expenses (including
attorneys' fees) incurred in connection with successfully establishing his right
to indemnification, in whole or in part, in any such proceeding shall also be
indemnified by the Corporation.

     8.  Limitations.  Notwithstanding anything to the contrary in this Article,
         -----------
except as set forth in Section 7 of the Article EIGHTH, the Corporation shall
not indemnify an Indemnitee in connection with a proceeding (or part thereof)
initiated by the Indemnitee unless the initiation thereof was approved by the
Board of Directors of the Corporation.  Notwithstanding anything to the contrary
in this Article, the Corporation shall not indemnify an Indemnitee to the extent
such Indemnitee is reimbursed from the proceeds of insurance, and in the event
the Corporation makes any indemnification payments to an Indemnitee and such
Indemnitee is subsequently reimbursed from the proceeds of insurance, such
Indemnitee shall promptly refund such indemnification payments to the
Corporation to the extent of such insurance reimbursement.

     9.  Subsequent Amendment.  No amendment, termination or repeal of this
         --------------------
Article or of the relevant provisions of the General Corporation Law of Delaware
or any other applicable laws shall affect or diminish in any way the rights of
any Indemnitee to indemnification under the provisions hereof with respect to
any action, suit, proceeding or investigation arising out of or relating to any
actions, transactions or facts occurring prior to the final adoption of such
amendment, termination or repeal.

     10.  Other Rights.  The indemnification and advancement of expenses
          ------------
provided by this Article shall not be deemed exclusive of any other rights to
which an Indemnitee seeking indemnification or advancement of expenses may be
entitled under any law (common or statutory), agreement or vote of stockholders
or disinterested directors or otherwise, both as to action in his official
capacity and as to action in any other capacity while holding office for the
Corporation, and shall continue as to an Indemnitee who has ceased to be a
director or officer, and shall inure to the benefit of the estate, heirs,
executors and administrators of the Indemnitee.  Nothing contained in this
Article shall be deemed to prohibit, and the Corporation is specifically
authorized to enter into, agreements with officers and directors providing
indemnification rights and procedures different from those set forth in this
Article.  In addition, the Corporation may, to the extent authorized from time
to time by its Board of Directors, grant indemnification rights to

                                      -10-
<PAGE>

other employees or agents of the Corporation or other persons serving the
Corporation and such rights may be equivalent to, or greater or less than, those
set forth in this Article.

     11.  Partial Indemnification.  If an Indemnitee is entitled under any
          -----------------------
provision of this Article to indemnification by the Corporation for some or a
portion of the expenses (including attorneys' fees), judgments, fines or amounts
paid in settlement actually and reasonably incurred by him or on his behalf in
connection with any action, suit, proceeding or investigation and any appeal
therefrom but not, however, for the total amount thereof, the Corporation shall
nevertheless indemnify the Indemnitee for the portion of such expenses
(including attorneys' fees), judgments, fines or amounts paid in settlement to
which the Indemnitee is entitled.

     12.  Insurance.  The Corporation may purchase and maintain insurance, at
          ---------
its expense, to protect itself and any director, officer, employee or agent of
the Corporation or another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan) against any expense,
liability or loss incurred by him in any such capacity, or arising out of his
status as such, 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 Delaware.

     13.  Merger or Consolidation.  If the Corporation is merged into or
          -----------------------
consolidated with another corporation and the Corporation is not the surviving
corporation, the surviving corporation shall assume the obligations of the
Corporation under this Article with respect to any action, suit, proceeding or
investigation arising out of or relating to any actions, transactions or facts
occurring prior to the date of such merger or consolidation.

     14.  Savings Clause.  If this Article or any portion hereof shall be
          --------------
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each Indemnitee as to any expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with any action, suit, proceeding or investigation, whether civil,
criminal or administrative, including an action by or in the right of the
Corporation, to the fullest extent permitted by any applicable portion of this
Article that shall not have been invalidated and to the fullest extent permitted
by applicable law.

     15.  Definitions.  Terms used herein and defined in Section 145(h) and
          -----------
Section 145(i) of the General Corporation Law of Delaware shall have the
respective meanings assigned to such terms in such Section 145(h) and Section
145(i).

     16.  Subsequent Legislation.  If the General Corporation Law of Delaware is
          ----------------------
amended after adoption of this Article to expand further the indemnification
permitted to Indemnitees, then the Corporation shall indemnify such persons to
the fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

     NINTH.  This Article is inserted for the management of the business and for
the conduct of the affairs of the Corporation.

     1.  Number of Directors; Election of Directors.  The number of directors of
         ------------------------------------------
the Corporation shall not be less than three.  The exact number of directors
within the limitations specified in the preceding sentence shall be determined
from time to time by, or in the manner

                                      -11-
<PAGE>

provided in, the By-laws of the Corporation. Election of directors need not be
by written ballot, except as and to the extent provided in the By-laws of the
Corporation.

     2.  Classes of Directors.  Except for any directors entitled to be elected
         --------------------
by the holders of preferred stock or any other securities of the Corporation
(other than common stock), the Board of Directors shall be and is divided into
three classes:  Class I, Class II and Class III.  No one class shall have more
than one director more than any other class.  If a fraction is contained in the
quotient arrived at by dividing the authorized number of directors by three,
then, if such fraction is one-third, the extra director shall be a member of
Class I, and if such fraction is two-thirds, one of the extra directors shall be
a member of Class I and one of the extra directors shall be a member of Class
II, unless otherwise provided by resolution of the Board of Directors.

     3.  Terms of Office.  Except for any directors entitled to be elected by
         ---------------
the holders of preferred stock or any other securities of the Corporation (other
than common stock), each director shall serve for a term ending on the date of
the third annual meeting following the annual meeting at which such director was
elected; provided, that each initial director in Class I shall serve for a term
         --------
expiring at the Corporation's annual meeting of stockholders held in 2001; each
initial director in Class II shall serve for a term expiring at the
Corporation's annual meeting of stockholders held in 2002; and each initial
director in Class III shall serve for a term expiring at the Corporation's
annual meeting of stockholders held in 2003; provided further, that the term of
                                             -------- -------
each director shall continue until the election and qualification of his
successor and be subject to his earlier death, resignation or removal.

     4.  Allocation of Directors Among Classes in the Event of Increases or
         ------------------------------------------------------------------
Decreases in the Authorized Number of Directors.  In the event of any increase
- -----------------------------------------------
or decrease in the authorized number of directors, (i) each director then
serving as such shall nevertheless continue as a director of the class of which
he is a member until the expiration of his current term, subject to his earlier
death, resignation or removal and (ii) the newly created or eliminated
directorships resulting from such increase or decrease shall be apportioned by
the Board of Directors among the three classes of directors in accordance with
the provisions of Section 2 of this Article NINTH.  To the extent possible,
consistent with the provisions of Section 2 of this Article NINTH, any newly
created directorships shall be added to those classes whose terms of office are
to expire at the latest dates following such allocation, and any newly
eliminated directorships shall be subtracted from those classes whose terms of
offices are to expire at the earliest dates following such allocation, unless
otherwise provided from time to time by resolution of the Board of Directors.

     5.  Quorum.  A majority of the directors at any time in office shall
         ------
constitute a quorum for the transaction of business.  In the event one or more
of the directors shall be disqualified to vote at any meeting, then the required
quorum shall be reduced by one for each director so disqualified, provided that
in no case shall less than one-third of the number of directors fixed pursuant
to Section 1 of this Article NINTH constitute a quorum.  If at any meeting of
the Board of Directors there shall be less than such a quorum, a majority of the
directors present may adjourn the meeting from time to time without further
notice other than announcement at the meeting, until a quorum shall be present.

                                      -12-
<PAGE>

     6.  Action at Meeting.  Every act or decision done or made by a majority of
         -----------------
the directors present at a meeting duly held at which a quorum is present shall
be regarded as the act of the Board of Directors unless a greater number is
required by law, by this Certificate of Incorporation, or by the By-laws of the
Corporation.

     7.  Removal.  Prior to July 2, 2001 (or if earlier the date that the
         -------
Stockholders' Voting Agreement dated as of June 30, 1999 by and among the
corporation, CBS Corporation and Banyan Systems Incorporated (the "Voting
Agreement") is terminated or expires), directors of the Corporation may be
removed by the stockholders, with or without cause, by the affirmative vote of
the holders of at least a majority of the votes which all the stockholders would
be entitled to cast in any annual election of directors or class of directors.
On and after July 2, 2001 (or if earlier the date that the Voting Agreement is
terminated or expires), directors of the Corporation may be removed only for
cause by the affirmative vote of the holders of at least seventy-five percent
(75%) of the votes which all the stockholders would be entitled to cast in any
annual election of directors or class of directors.  Notwithstanding the prior
two sentences, any directors entitled to be elected by the holders of preferred
stock or any other securities of the Corporation (other than common stock) may
be removed in accordance with the applicable provisions of this Certificate of
Incorporation.

     8.  Vacancies.  Except for any directors entitled to be elected by the
         ---------
holders of preferred stock or any other securities of the Corporation (other
than common stock), any vacancy in the Board of Directors, however occurring,
including a vacancy resulting from an enlargement of the Board, shall be filled
only by vote of a majority of the directors then in office, although less than a
quorum, or by a sole remaining director.  A director elected to fill a vacancy
shall be elected to hold office until the next election of the class for which
such director shall have been chosen, subject to the election and qualification
of his successor and to his earlier death, resignation or removal.

     9.  Stockholder Nominations and Introduction of Business, Etc.  Advance
         ----------------------------------------------------------
notice of stockholder nominations for election of directors and other business
to be brought by stockholders before a meeting of stockholders shall be given in
the manner provided by the By-laws of the Corporation.

          ---------------------
this Certificate of Incorporation or the By-laws of the Corporation, and
notwithstanding the fact that a lesser percentage may be specified by law, the
affirmative vote of the holders of at least seventy-five percent (75%) of the
votes which all the stockholders would be entitled to cast in any annual
election of directors or class of directors shall be required to amend or
repeal, or to adopt any provision inconsistent with, this Article NINTH.

consent in lieu of a meeting.  Notwithstanding any other provisions of law, this
Certificate of Incorporation or the By-laws of the Corporation, and

votes which all the stockholders would be entitled to cast in any annual

     1.1  Place of Meetings.  All meetings of stockholders shall be held at such
          -----------------
place within or without the State of Delaware as may be designated from time to
time by the Board of Directors or the President or, if not so designated, at the
registered office of the corporation.

     1.2  Annual Meeting.  The annual meeting of stockholders for the election
          --------------
of directors and for the transaction of such other business as may properly be

where the meeting is to be held) at the time and place to be fixed by the Board
of Directors or the President and stated in the notice of the meeting if no
annual meeting is held in accordance with the foregoing provisions, the Board of
Directors shall cause the meeting to be held as soon thereafter as convenient.
If no annual meeting is held in accordance with the foregoing provisions, a
special meeting may be held in lieu of the annual meeting, and any action taken
at that special meeting shall have the same effect as if it had been taken at
the annual meeting, and in such case all references in these By-laws to the
annual meeting of the stockholders shall be deemed to refer to such special
meeting.

     1.3  Special Meetings.  Special meetings of stockholders may be called at
          ----------------
any time by the President or by the Board of Directors.  Business transacted at
any special meeting of stockholders shall be limited to matters relating to the
purpose or purposes stated in the notice of meeting.

     1.4  Notice of Meetings.  Except as otherwise provided by law, written
          ------------------
notice of each meeting of stockholders, whether annual or special, shall be

                                  STOCKHOLDERS

     1.1 Place of Meetings. All meetings of stockholders shall be held at such
         -----------------
place within or without the State of Delaware as may be designated from time to
time by the Board of Directors, the Chairman of the Board or the Chief Executive
Officer or, if not so designated, at the registered office of the corporation.

     1.2 Annual Meeting. The annual meeting of stockholders for the election of
         --------------
directors and for the transaction of such other business as may properly be
brought before the meeting shall be held on a date to be fixed by the Board of
Directors, the Chairman of the Board or the Chief Executive Officer (which date
shall not be a legal holiday in the place where the meeting is to be held) at
the time and place to be fixed by the Board of Directors, the Chairman of the
Board or the Chief Executive Officer and stated in the notice of the meeting. If
no annual meeting is held in accordance with the foregoing provisions, the Board
of Directors shall cause the meeting to be held as soon thereafter as is
convenient. If no annual meeting is held in accordance with the foregoing
provisions, a special meeting may be held in lieu of the annual meeting, and any
action taken at that special meeting shall have the same effect as if it had
been taken at the annual meeting, and in such case all references in these By-
laws to the annual meeting of the stockholders shall be deemed to refer to such
special meeting.

     1.3 Special Meetings. Special meetings of stockholders for any purpose or
         ----------------
purposes may be called at any time by the Board of Directors, the Chairman of
the Board or the Chief Executive Officer, but such special meetings may not be
called by any other person or persons. Business transacted at any special
meeting of stockholders shall be limited to matters relating to the purpose or
purposes stated in the notice of meeting.

     1.4 Notice of Meetings. Except as otherwise provided by law, written notice
         ------------------
of each meeting of stockholders, whether annual or special, shall be given not
less than 10 nor more than 60 days before the date of the meeting to each
stockholder entitled to vote at such meeting. The notices of all meetings shall
state the place, date and hour of the meeting. The notice of a special meeting
shall state, in addition, the purpose or purposes for which the meeting is
called. If mailed, notice shall be deemed given when deposited in the United
States mail, postage prepaid, directed to the stockholder at such stockholder's
address as it appears on the records of the corporation.

     1.5 Voting List. The Secretary shall prepare, at least 10 days before every
         -----------
meeting of stockholders, a complete list of the stockholders entitled to vote at
the meeting, arranged in
<PAGE>

alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least 10 days prior to the
meeting, at a place within the city where the meeting is to be held, which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place where the meeting is to be held. The list shall also be produced and kept
at the time and place of the meeting during the whole time of the meeting, and
may be inspected by any stockholder who is present.

     1.6 Quorum. Except as otherwise provided by law, the Certificate of
         ------
Incorporation or these By-laws, the holders of a majority of the shares of the
capital stock of the corporation issued and outstanding and entitled to vote at
the meeting, present in person or represented by proxy, shall constitute a
quorum for the transaction of business. A quorum, once established at a meeting,
shall not be broken by the withdrawal of enough votes to leave less than a
quorum.

     1.7 Adjournments. Any meeting of stockholders may be adjourned from time to
         ------------
time to any other time and to any other place at which a meeting of stockholders
may be held under these By-laws by the stockholders present or represented at
the meeting and entitled to vote, although less than a quorum, or, if no
stockholder is present, by any officer entitled to preside at or to act as
secretary of such meeting. It shall not be necessary to notify any stockholder
of any adjournment of less than 30 days if the time and place of the adjourned
meeting are announced at the meeting at which adjournment is taken, unless after
the adjournment a new record date is fixed for the adjourned meeting. At the
adjourned meeting, the corporation may transact any business which might have
been transacted at the original meeting.

     1.8 Voting and Proxies. Each stockholder shall have one vote for each share
         ------------------
of stock entitled to vote held of record by such stockholder and a proportionate
vote for each fractional share so held, unless otherwise provided by law or the
Certificate of Incorporation. Each stockholder of record entitled to vote at a
meeting of stockholders may vote in person or may authorize another person or
persons to vote for him by a proxy executed in writing (or in such other manner
permitted by the General Corporation Law of Delaware) by the stockholder or his
authorized agent and delivered (including by electronic transmission) to the
Secretary of the corporation. No such proxy shall be voted upon after three
years from the date of its execution, unless the proxy expressly provides for a
longer period.

     1.9 Action at Meeting. When a quorum is present at any meeting, any matter
       -----------------
to be voted upon by the stockholders at such meeting shall be decided by the
affirmative vote of the holders of a majority of the stock present or
represented and voting on such matter (or if there are two or more classes of
stock entitled to vote as separate classes, then in the case of each such

                                      -2-
<PAGE>

class, the holders of a majority of the stock of that class present or
represented and voting on such matter), except when a different vote is required
by law, the Certificate of Incorporation or these By-laws. When a quorum is
present at any meeting, any election by stockholders shall be determined by a
plurality of the votes cast by the stockholders entitled to vote on the
election.

however, that (i) in the case of the annual meeting of stockholders of the

be so received not earlier than the ninetieth day prior to such annual
meeting and not later than the close of business on the later of (A) the

public disclosure of the date of such annual meeting was made, whichever
first occurs; or (b) in the case of an election of directors at a special
meeting of stockholders, not earlier than the ninetieth day prior to such
special meeting and not later than the close of business on the later of
(i) the sixtieth day prior to such special meeting and (ii) the tenth day

1934, as amended; (b) as to the stockholder giving the notice (i) such
stockholder's name and address, as they appear on the corporation's books, (ii)
the class and number of shares of stock of the corporation which are owned,
beneficially and of record, by such stockholder, (iii) a description of all
arrangements or understandings between such stockholder and each proposed
nominee and any other person or persons (including their names) pursuant to
which the nomination(s) are to be made by such stockholder and (iv) a
representation that such stockholder intends to appear in person or by proxy at

addition, to be effective, the stockholder's notice must be accompanied by the
written consent of the proposed nominee to serve as a director if elected. The
corporation may require any proposed nominee to furnish such other information
as may reasonably be required to determine the eligibility of such proposed
nominee to serve as a director of the corporation.

          (c) The chairman of any meeting shall, if the facts warrant, determine
that a nomination was not made in accordance with the provisions of this
Section 1.10, and if he should so determine, he shall so declare to the meeting
and the defective nomination shall be disregarded.

          (d) Except as otherwise required by law, nothing in this Section 1.10
shall obligate the corporation or the Board of Directors to include in any proxy
statement or other stockholder communication distributed on behalf of the
corporation or the Board of Directors information with respect to any nominee
for director submitted by a stockholder.

     1.11 Notice of Business at Annual Meetings.

year's annual meeting; provided, however, that in the case of the annual meeting

proposal of such business by such stockholder and any material interest of the
stockholder or such beneficial owner, if any, in such business, and (v) a
representation that such stockholder intends to appear in person or by proxy at
the annual meeting to bring such business before the meeting. Notwithstanding
anything in these By-laws to the contrary, no business shall be conducted at any

forth in this Section 1.11; provided that any stockholder proposal which
complies with Rule 14a-8 of the proxy rules (or any successor provision)
promulgated under the Securities Exchange Act of 1934, as amended, and is to be
included in the corporation's proxy statement for an annual meeting of
stockholders shall be deemed to comply with the requirements of this Section
1.11.

          (c) The chairman of any meeting shall, if the facts warrant, determine

the holders of preferred stock or any other securities of the corporation (other

he is a member until the expiration of his current term,  subject to his earlier

to Section 2.2 constitute a quorum. If at any meeting of the Board of Directors
there shall be less than such a quorum, a majority of the directors present may
adjourn the meeting from time to time without further notice other than
announcement at the meeting, until a quorum shall be present.

   2.7  Action at Meeting. Every act or decision done or made by a majority of

     Re:  Registration Statement on Form S-1
          ----------------------------------

Ladies and Gentlemen:

          This opinion is furnished to you in connection with a Registration
Statement on Form S-1 (File No. 333-90013) (the "Registration Statement") filed
with the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Securities Act"), for the registration
of 6,325,000 shares of Common Stock, $0.01 par value per share (the "Shares"),
of Switchboard Incorporated, a Delaware corporation (the "Company"), including
825,000 Shares issuable upon exercise of an over-allotment option granted by the
Company.

          The Shares are to be sold by the Company pursuant to an underwriting
agreement (the "Underwriting Agreement") to be entered into by and among the
Company and FleetBoston Robertson Stephens Inc., J.P Morgan Securities Inc., The
Robinson-Humphrey Company, LLC and SoundView Technology Group, Inc., as
representatives of the several underwriters named in the Underwriting Agreement,
the form of which has been filed as Exhibit 1 to the Registration Statement.

          We are acting as counsel for the Company in connection with the issue
and sale by the Company of the Shares.  We have examined signed copies of the
Registration Statement as filed with the Commission.  We have also examined and
relied upon the Underwriting Agreement, minutes of meetings of the stockholders
and the Board of Directors of the Company as provided to us by the Company,
stock record books of the Company as provided to us by the Company, the
Certificate of Incorporation and By-Laws of the Company, each as restated and/or
amended to date, and such other documents as we have deemed necessary for
purposes of rendering the opinions hereinafter set forth.

          In our examination of the foregoing documents, we have assumed the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals, the conformity to original documents of all documents submitted to
us as copies, the authenticity of the originals of such latter documents and the
legal competence of all signatories to such documents.

          We assume that the appropriate action will be taken, prior to the
offer and sale of the Shares in accordance with the Underwriting Agreement, to
register and qualify the Shares for sale under all applicable state securities
or "blue sky" laws.

          We express no opinion herein as to the laws of any state or
jurisdiction other than the state laws of the Commonwealth of Massachusetts, the
General Corporation Law of the State of Delaware and the federal laws of the
United States of America.

          Based upon and subject to the foregoing, we are of the opinion that
the Shares have been duly authorized for issuance and, when the Shares are
issued and paid for in accordance with the terms and conditions of the
Underwriting Agreement, the Shares will be validly issued, fully paid and
nonassessable.

          It is understood that this opinion is to be used only in connection
with the offer and sale of the Shares while the Registration Statement is in
effect.

          Please note that we are opining only as to the matters expressly set
forth herein, and no opinion should be inferred as to any other matters.  This
opinion is based upon currently existing statutes, rules, regulations and
judicial decisions, and we disclaim any obligation to advise you of any change
in any of these sources of law or subsequent legal or factual developments which
might affect any matters or opinions set forth herein.

          We hereby consent to the filing of this opinion with the Commission as
an exhibit to the Registration Statement in accordance with the requirements of
Item 601(b)(5) of Regulation S-K under the Securities Act and to the use of our
name therein and in the related Prospectus under the caption "Validity of Common
Stock."  In giving such consent, we do not hereby admit that we are in the
category of persons whose consent is required under Section 7 of the Securities
Act or the rules and regulations of the Commission.


                                 Very truly yours,


                                 /s/ Hale and Dorr LLP

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

                           SWITCHBOARD INCORPORATED

                           1999 Stock Incentive Plan

1.   Purpose
     -------

     The purpose of this 1999 Stock Incentive Plan (the "Plan") of Switchboard
Incorporated, a Delaware corporation (the "Company"), is to advance the
interests of the Company's stockholders by enhancing the Company's ability to
attract, retain and motivate persons who make (or are expected to make)
important contributions to the Company by providing such persons with equity
ownership opportunities and performance-based incentives and thereby better
aligning the interests of such persons with those of the Company's stockholders.
Except where the context otherwise requires, the term "Company" shall include
any of the Company's present or future subsidiary corporations as defined in
Section 424(f) of the Internal Revenue Code of 1986, as amended, and any
regulations promulgated thereunder (the "Code").

2.   Eligibility
     -----------

     All of the Company's employees, officers, directors, consultants and
advisors (and any individuals who have accepted an offer for employment) are
eligible to be granted options, restricted stock awards, or other stock-based
awards (each, an "Award") under the Plan.  Each person who has been granted an
Award under the Plan shall be deemed a "Participant."

3.   Administration, Delegation
     --------------------------

     (a)  Administration by Board of Directors. The Plan will be administered by
          ------------------------------------
the Board of Directors of the Company (the "Board"). The Board shall have
authority to grant Awards and to adopt, amend and repeal such administrative
rules, guidelines and practices relating to the Plan as it shall deem advisable.
The Board may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem expedient to carry the Plan into effect and it shall be the sole and final
judge of such expediency. All decisions by the Board shall be made in the
Board's sole discretion and shall be final and binding on all persons having or
claiming any interest in the Plan or in any Award. No director or person acting
pursuant to the authority delegated by the Board shall be liable for any action
or determination relating to or under the Plan made in good faith.

     (b)  Delegation to Executive Officers. To the extent permitted by
          --------------------------------
applicable law, the Board may delegate to one or more executive officers of the
Company the power to make Awards and exercise such other powers under the Plan
as the Board
<PAGE>

may determine, provided that the Board shall fix the maximum number of shares
subject to Awards and the maximum number of shares for any one Participant to be
made by such executive officers.

     (c)  Appointment of Committees. To the extent permitted by applicable
          -------------------------
law,the Board may delegate any or all of its powers under the Plan to one or
more committees or subcommittees of the Board (a "Committee"). All references in
the Plan to the "Board" shall mean the Board or a Committee of the Board or the
executive officer referred to in Section 3(b) to the extent that the Board's
powers or authority under the Plan have been delegated to such Committee or
executive officer.

4.  Stock Available for Awards
    --------------------------

     (a)  Number of Shares. Subject to adjustment under Section 8, Awards may be
          ----------------
made under the Plan for up to the sum of (i) One Million Five Hundred Thousand
(1,500,000) shares of common stock, $0.01 par value per share, of the Company
(the "Common Stock") plus (ii) such additional number of shares of Common Stock
(up to 3,000,000 shares) as is equal to the sum of (x) the number of shares
which remain available for grant under the Company's 1996 Stock Incentive Plan
(the "1996 Plan") upon the closing of the Company's initial public offering and
(y) the number of shares subject to awards granted under the 1996 Plan which are
not actually issued pursuant to such awards because such awards expire or are
terminated, surrendered or canceled without having been fully exercised or are
forfeited in whole or in part or otherwise result in any Common Stock not being
issued. If any Award expires or is terminated, surrendered or canceled without
having been fully exercised or is forfeited in whole or in part or results in
any Common Stock not being issued, the unused Common Stock covered by such Award
shall again be available for the grant of Awards under the Plan, subject,
however, in the case of Incentive Stock Options (as hereinafter defined), to any
limitation required under the Code. Shares issued under the Plan may consist in
whole or in part of authorized but unissued shares or treasury shares.

     (b)  Per-Participant Limit. Subject to adjustment under Section 8, for
          ---------------------
Awards granted after the Common Stock is registered under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), the maximum number of
shares of Common Stock with respect to which an Award may be granted to any
Participant under the Plan shall be 1,000,000 per calendar year. The per-
Participant limit described in this Section 4(b) shall be construed and applied
consistently with Section 162(m) of the Code ("Section 162(m)").

5.  Stock Options
    -------------

                                      -2-
<PAGE>

     (a)  General.  The Board may grant options to purchase Common Stock (each,
          -------
an "Option") and determine the number of shares of Common Stock to be covered
 by each Option, the exercise price of each Option and the conditions and
 limitations applicable to the exercise of each Option, including conditions
 relating to applicable federal or state securities laws, as it considers
 necessary or advisable. An Option which is not intended to be an Incentive
 Stock Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
 Option."

     (b)  Incentive Stock Options.  An Option that the Board intends to be an
          -----------------------
  "incentive stock option" as defined in Section 422 of the Code (an "Incentive
  Stock Option") shall only be granted to employees of the Company and shall be
  subject to and shall be construed consistently with the requirements of
  Section 422 of the Code. The Company shall have no liability to a Participant,
  or any other party, if an Option (or any part thereof) which is intended to be
  an Incentive Stock Option is not an Incentive Stock Option.

     (c)  Exercise Price.  The Board shall establish the exercise price at
          --------------
the time each Option is granted and specify it in the applicable option
agreement.

     (d)  Duration of Options.  Each Option shall be exercisable at such times
          -------------------
and subject to such terms and conditions as the Board may specify in the
applicable option agreement.

     (e)  Exercise of Option.  Options may be exercised by delivery to the
          ------------------
Company of a written notice of exercise signed by the proper person or by any
other form of notice (including electronic notice) approved by the Board
together with payment in full as specified in Section 5(f) for the number of
shares for which the Option is exercised.

     (f)  Payment Upon Exercise.  Common Stock purchased upon the exercise of an
          ----------------------
Option granted under the Plan shall be paid for as follows:

          (1)  in cash or by check, payable to the order of the Company;

          (2)  except as the Board may, in its sole discretion, otherwise
provide in an option agreement, by (i) delivery of an irrevocable and
unconditional undertaking by a creditworthy broker to deliver promptly to the
Company sufficient funds to pay the exercise price or (ii) delivery by the
Participant to the Company of a copy of irrevocable and unconditional
instructions to a creditworthy broker to deliver promptly to the Company cash or
a check sufficient to pay the exercise price;

                                      -3-
<PAGE>

          (3)  when the Common Stock is registered under the Exchange Act, by
delivery of shares of Common Stock owned by the Participant valued at their fair
market value as determined by (or in a manner approved by) the Board in good
faith ("Fair Market Value"), provided (i) such method of payment is then
permitted under applicable law and (ii) such Common Stock was owned by the
Participant at least six months prior to such delivery;

          (4)  to the extent permitted by the Board, in its sole discretion by
(i) delivery of a promissory note of the Participant to the Company on terms
determined by the Board, or (ii) payment of such other lawful consideration as
the Board may determine; or

          (5)  by any combination of the above permitted forms of payment.

6.   Restricted Stock
     ----------------

     (a)  Grants.  The Board may grant Awards entitling recipients to acquire
          ------
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require forfeiture of such shares if issued at no cost) from the recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable restriction period or periods
established by the Board for such Award (each, a "Restricted Stock Award").

     (b)  Terms and Conditions.  The Board shall determine the terms and
          --------------------
conditions of any such Restricted Stock Award, including the conditions for
repurchase (or forfeiture) and the issue price, if any. Any stock certificates
issued in respect of a Restricted Stock Award shall be registered in the name of
the Participant and, unless otherwise determined by the Board, deposited by the
Participant, together with a stock power endorsed in blank, with the Company (or
its designee). At the expiration of the applicable restriction periods, the
Company (or such designee) shall deliver the certificates no longer subject to
such restrictions to the Participant or if the Participant has died, to the
beneficiary designated, in a manner determined by the Board, by a Participant to
receive amounts due or exercise rights of the Participant in the event of the
Participant's death (the "Designated Beneficiary"). In the absence of an
effective designation by a Participant, Designated Beneficiary shall mean the
Participant's estate.

7.   Other Stock-Based Awards
     ------------------------

     The Board shall have the right to grant other Awards based upon the Common
Stock having such terms and conditions as the Board may determine, including the

                                      -4-
<PAGE>

grant of shares based upon certain conditions, the grant of securities
convertible into Common Stock and the grant of stock appreciation rights.

8.   Adjustments for Changes in Common Stock and Certain Other Events
     ----------------------------------------------------------------

     (a)  Changes in Capitalization. In the event of any stock split, reverse
          -------------------------
stock split, stock dividend, recapitalization, combination of shares,
reclassification of shares, spin-off or other similar change in capitalization
or event, or any distribution to holders of Common Stock other than a normal
cash dividend, (i) the number and class of securities available under this Plan,
(ii) the per-Participant limit set forth in Section 4(b), (iii) the number and
class of securities and exercise price per share subject to each outstanding
Option, (iv) the repurchase price per share subject to each outstanding
Restricted Stock Award, and (v) the terms of each other outstanding Award shall
be appropriately adjusted by the Company (or substituted Awards may be made, if
applicable) to the extent the Board shall determine, in good faith, that such an
adjustment (or substitution) is necessary and appropriate. If this Section 8(a)
applies and Section 8(c) also applies to any event, Section 8(c) shall be
applicable to such event, and this Section 8(a) shall not be applicable.

     (b)  Liquidation or Dissolution.  In the event of a proposed liquidation or
          --------------------------
dissolution of the Company, the Board shall upon written notice to the
Participants provide that all then unexercised Options will (i) become
exercisable in full as of a specified time at least 10 business days prior to
the effective date of such liquidation or dissolution and (ii) terminate
effective upon such liquidation or dissolution, except to the extent exercised
before such effective date. The Board may specify the effect of a liquidation or
dissolution on any Restricted Stock Award or other Award granted under the Plan
at the time of the grant of such Award.

     (c)  Acquisition Events
          ------------------

          (1)  Definition.  An "Acquisition Event" shall mean: (a) any merger or
               ----------
consolidation of the Company with or into another entity as a result of which
the Common Stock is converted into or exchanged for the right to receive cash,
securities or other property or (b) any exchange of shares of the Company for
cash, securities or other property pursuant to a statutory share exchange
transaction.

          (2)  Consequences of an Acquisition Event on Options. Upon the
               -----------------------------------------------
occurrence of an Acquisition Event, or the execution by the Company of any
agreement with respect to an Acquisition Event, the Board shall provide that all
outstanding Options shall be assumed, or equivalent options shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof). For purposes hereof, an Option shall be considered to be assumed if,
following consummation of the Acquisition Event, the

                                      -5-
<PAGE>

Option confers the right to purchase, for each share of Common Stock subject to
the Option immediately prior to the consummation of the Acquisition Event, the
consideration (whether cash, securities or other property) received as a result
of the Acquisition Event by holders of Common Stock for each share of Common
Stock held immediately prior to the consummation of the Acquisition Event (and
if holders were offered a choice of consideration, the type of consideration
chosen by the holders of a majority of the outstanding shares of Common Stock);
provided, however, that if the consideration received as a result of the
Acquisition Event is not solely common stock of the acquiring or succeeding
corporation (or an affiliate thereof), the Company may, with the consent of the
acquiring or succeeding corporation, provide for the consideration to be
received upon the exercise of Options to consist solely of common stock of the
acquiring or succeeding corporation (or an affiliate thereof) equivalent in Fair
Market Value to the per share consideration received by holders of outstanding
shares of Common Stock as a result of the Acquisition Event.

          Notwithstanding the foregoing, if the acquiring or succeeding
corporation (or an affiliate thereof) does not agree to assume, or substitute
for, such Options, then the Board shall, upon written notice to the
Participants, provide that all then outstanding Options will become vested and
exercisable with respect to 25% of their unvested shares as of a specified time
prior to the Acquisition Event and all of such Options (whether or not then
exercisable) will terminate immediately prior to the consummation of such
Acquisition Event, except to the extent exercised by the Participants before the
consummation of such Acquisition Event; provided, however, that in the event of
an Acquisition Event under the terms of which holders of Common Stock will
receive upon consummation thereof a cash payment for each share of Common Stock
surrendered pursuant to such Acquisition Event (the "Acquisition Price"), then
the Board may instead provide that all outstanding Options shall terminate upon
consummation of such Acquisition Event and that each Participant shall receive,
in exchange therefor, a cash payment equal to the amount (if any) by which (A)
the Acquisition Price multiplied by the number of shares of Common Stock with
respect to which such outstanding Options are then exercisable (including the
25% additional vested shares the vesting of which accelerated pursuant to the
preceding clauses of this paragraph), exceeds (B) the aggregate exercise price
of such Options.

          (3)  Consequences of an Acquisition Event on Restricted Stock Awards.
               ---------------------------------------------------------------
Upon the occurrence of an Acquisition Event, the repurchase and other rights of
the Company under each outstanding Restricted Stock Award shall be assumed or
substituted by and shall inure to the benefit of the Company's successor and
shall apply to the cash, securities or other property which the Common Stock was
converted into or exchanged for pursuant to such Acquisition Event in the same
manner and to the same extent as they applied to the Common Stock subject to
such Restricted Stock Award.

                                      -6-
<PAGE>

          (4)  Consequences of an Acquisition Event on Other Awards. The Board
               ----------------------------------------------------
shall specify the effect of an Acquisition Event on any other Award granted
under the Plan at the time of the grant of such Award.

9.   General Provisions Applicable to Awards
     ---------------------------------------

     (a) Transferability of Awards.  Except as the Board may otherwise determine
         -------------------------
or provide in an Award, Awards shall not be sold, assigned, transferred, pledged
or otherwise encumbered by the person to whom they are granted, either
voluntarily or by operation of law, except by will or the laws of descent and
distribution, and, during the life of the Participant, shall be exercisable only
by the Participant.  References to a Participant, to the extent relevant in the
context, shall include references to authorized transferees.

     (b) Documentation.  Each Award shall be evidenced by a written instrument
         -------------
in such form as the Board shall determine.  Each Award may contain terms and
conditions in addition to those set forth in the Plan.

     (c) Board Discretion.  Except as otherwise provided by the Plan, each Award
         ----------------
may be made alone or in addition or in relation to any other Award.  The terms
of each Award need not be identical, and the Board need not treat Participants
uniformly.

     (d) Termination of Status.  The Board shall determine the effect on an
         ---------------------
Award of the disability, death, retirement, authorized leave of absence or other
change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or Designated Beneficiary may exercise
rights under the Award.

     (e) Withholding.  Each Participant shall pay to the Company, or make
         -----------
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event creating the tax liability. Except as the Board may otherwise
provide in an Award, when the Common Stock is registered under the Exchange Act,
Participants may, to the extent then permitted under applicable law, satisfy
such tax obligations in whole or in part by delivery of shares of Common Stock,
including shares retained from the Award creating the tax obligation, valued at
their Fair Market Value. The Company may, to the extent permitted by law, deduct
any such tax obligations from any payment of any kind otherwise due to a
Participant.

     (f) Amendment of Award.  The Board may amend, modify or terminate any
         ------------------
outstanding Award, including but not limited to, substituting therefor another
Award of the same or a different type, changing the date of exercise or
realization, and

                                      -7-
<PAGE>

converting an Incentive Stock Option to a Nonstatutory Stock Option, provided
that the Participant's consent to such action shall be required unless the Board
determines that the action, taking into account any related action, would not
materially and adversely affect the Participant.

     (g)  Conditions on Delivery of Stock.  The Company will not be obligated to
          -------------------------------
deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Award have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable securities laws and any applicable stock exchange or
stock market rules and regulations, and (iii) the Participant has executed and
delivered to the Company such representations or agreements as the Company may
consider appropriate to satisfy the requirements of any applicable laws, rules
or regulations.

     (h)  Acceleration.  The Board may at any time provide that any Options
          ------------
shall become immediately exercisable in full or in part, that any Restricted
Stock Awards shall be free of restrictions in full or in part or that any other
Awards may become exercisable in full or in part or free of some or all
restrictions or conditions, or otherwise realizable in full or in part, as the
case may be.

10.  Miscellaneous
     -------------

     (a)  No Right To Employment or Other Status.  No person shall have any
          --------------------------------------
claim or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly provided in the
applicable Award.

     (b)  No Rights As Stockholder.  Subject to the provisions of the applicable
          ------------------------
Award, no Participant or Designated Beneficiary shall have any rights as a
stockholder with respect to any shares of Common Stock to be distributed with
respect to an Award until becoming the record holder of such shares.
Notwithstanding the foregoing, in the event the Company effects a split of the
Common Stock by means of a stock dividend and the exercise price of and the
number of shares subject to such Option are adjusted as of the date of the
distribution of the dividend (rather than as of the record date for such
dividend), then an optionee who exercises an Option between the record date and
the distribution date for such stock dividend shall be entitled to receive, on
the distribution date, the stock dividend with respect to the shares of Common
Stock

                                      -8-
<PAGE>

acquired upon such Option exercise, notwithstanding the fact that such shares
were not outstanding as of the close of business on the record date for such
stock dividend.

     (c)  Effective Date and Term of Plan.  The Plan shall become effective on
          -------------------------------
the date on which it is adopted by the Board, but no Award granted to a
Participant that is intended to comply with Section 162(m) shall become
exercisable, vested or realizable, as applicable to such Award, unless and until
the Plan has been approved by the Company's stockholders to the extent
stockholder approval is required by Section 162(m) in the manner required under
Section 162(m) (including the vote required under Section 162(m)).  No Awards
shall be granted under the Plan after the completion of ten years from the
earlier of (i) the date on which the Plan was adopted by the Board or (ii) the
date the Plan was approved by the Company's stockholders, but Awards previously
granted may extend beyond that date.

     (d)  Amendment of Plan.  The Board may amend, suspend or terminate the Plan
          -----------------
or any portion thereof at any time, provided that to the extent required by

[__________________] shares (the "Shares") of common stock, $0.01 par value per
share, of the Company ("Common Stock") at $[__________] per Share. Unless
earlier terminated, this option shall expire on [_______] (the "Final Exercise
Date").

     It is intended that the option evidenced by this agreement shall be an
incentive stock option as defined in Section 422 of the Internal Revenue Code of

2.   Vesting Schedule.
     ----------------

     This option will become exercisable ("vest") as to 25% of the original

additional 6.25% of the original number of Shares at the end of each successive
three-month period following the first anniversary of the Grant Date until the
fourth anniversary of the Grant Date.

     The right of exercise shall be cumulative so that to the extent the option
is not exercised in any period to the maximum extent permissible it shall
continue to be exercisable, in whole or in part, with respect to all shares for
which it is vested until the earlier of the Final Exercise Date or the

writing, signed by the Participant, and received by the Company at its principal
office, accompanied by this agreement, and payment in full in the manner
provided in the Plan. The Participant may purchase less than the number of
shares covered hereby, provided that no partial exercise of this option may be

     (b)  Continuous Relationship with the Company Required. Except as otherwise
          -------------------------------------------------
provided in this Section 3, this option may not be exercised unless the

Notwithstanding the foregoing, if the Participant, prior to the Final Exercise
Date, violates the non-competition or confidentiality provisions of the Plan or
any employment contract, confidentiality and nondisclosure agreement or other
agreement between the Participant and the Company, the right to exercise this
option shall terminate immediately upon such violation.

     (d)  Exercise Period Upon Death or Disability. If the Participant dies or
          ----------------------------------------
becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to
the Final Exercise Date while he or she is an Eligible Participant and the
Company has not terminated such relationship for "cause" as specified in
paragraph (e) below, this option shall be exercisable, within the period of six
months following the date of death or disability of the Participant by the
Participant, provided, that, this option shall be exercisable only to the extent
             --------  ----
that this option was exercisable by the Participant on the date of his or her
death or disability, and further provided that this option shall not be

discharge. "Cause" shall mean, with respect to any Participant who has entered

Participant, "cause" shall mean (i) conviction or pleading guilty (including a
plea of nolo contendere) with respect to the commission of a felony, (ii) acts
of dishonesty or moral turpitude which are materially detrimental to the Company
and/or its affiliates as determined in good faith by the Board, (iii) failure of
the Participant to obey the reasonable and lawful orders of the Board or the
chief executive officer of the Company after written demand that the Participant
do so, (iv) gross negligence by the Participant in the performance of, or wilful
disregard by the Participant of, the Participant's obligations to the Company,
or (v) the breach by the Participant of any of the Participant's obligations of
confidentiality with respect to the Company. The Participant shall be considered
to have been discharged for "cause" if the Company determines, within 30 days
after the Participant's resignation, that discharge for cause was warranted.

4.   Withholding.
     -----------

     No Shares will be issued pursuant to the exercise of this option unless and
until the Participant pays to the Company, or makes provision satisfactory to
the Company for payment of, any federal, state or local withholding taxes

by will or the laws of descent and distribution, and, during the lifetime of the
Participant, this option shall be exercisable only by the Participant.

6.   Disqualifying Disposition.

                           SWITCHBOARD INCORPORATED

                       1999 Employee Stock Purchase Plan

     The purpose of this 1999 Employee Stock Purchase Plan (this "Plan") is to
provide eligible employees of Switchboard Incorporated, a Delaware corporation
(the "Company"), and certain of its subsidiaries with opportunities to purchase
shares of the Company's common stock, $0.01 par value per share (the "Common
Stock").  Three Hundred Thousand (300,000) shares of Common Stock in the
aggregate have been approved for this purpose.  This Plan is intended to qualify
as an "employee stock purchase plan" as defined in Section 423 of the Internal
Revenue Code of 1986, as amended (the "Code"), and the regulations promulgated
thereunder, and shall be interpreted consistent therewith.

     1.   Administration.  The Plan will be administered by the Board or by a
          --------------
Committee appointed by the Board (the "Committee").  The Board or the Committee
has authority to make rules and regulations for the administration of the Plan
and its interpretation and decisions with regard thereto shall be final and
conclusive.

     2.   Eligibility.  All employees of the Company, including Directors who
          -----------
are employees, and all employees of any subsidiary of the Company (as defined in
Section 424(f) of the Code) designated by the Board or the Committee from time
to time (a "Designated Subsidiary"), are eligible to participate in any one or
more of the offerings of Options (as defined in Section 9) to purchase Common
Stock under the Plan provided that:

          (a)  they are customarily employed by the Company or a Designated
     Subsidiary for more than 20 hours a week and for more than five months in a
     calendar year; and

          (b)  they have been employed by the Company or a Designated Subsidiary
     for at least three months prior to enrolling in the Plan; and

          (c)  they are employees of the Company or a Designated Subsidiary on
     the first day of the applicable Plan Period (as defined below).

     No employee may be granted an option hereunder if such employee,
immediately after the option is granted, owns 5% or more of the total combined
voting power or value of the stock of the Company or any subsidiary.  For
purposes of the preceding sentence, the attribution rules of Section 424(d) of
the Code shall apply in
<PAGE>

determining the stock ownership of an employee, and all stock which the employee
has a contractual right to purchase shall be treated as stock owned by the
employee.

     3.   Offerings.  The Company will make one or more offerings ("Offerings")
          ---------
to employees to purchase stock under this Plan.  Offerings will begin on such
date or dates as may be established by the Board or the Committee from time to
time (the "Offering Commencement Dates"). Each Offering Commencement Date will
begin a six-month period (a "Plan Period") during which payroll deductions will
be made and held for the purchase of Common Stock at the end of the Plan Period.
The Board or the Committee may, at its discretion, choose a different Plan
Period of twelve (12) months or less for its Offerings.  Notwithstanding
anything to the contrary, the first Plan Period shall begin on the first date
that the Common Stock is publicly traded following the Company's initial public
offering ("IPO") and shall end on the date six months thereafter.

     4.   Participation.  An employee eligible on the Offering Commencement Date
          -------------
of any Offering may participate in such Offering by completing and forwarding a
payroll deduction authorization form to the employee's appropriate payroll
office at least 14 days prior to the applicable Offering Commencement Date.  The
form will authorize a regular payroll deduction from the Compensation received
by the employee during the Plan Period.  Unless an employee files a new form or
withdraws from the Plan, his deductions and purchases will continue at the same
rate for future Offerings under the Plan as long as the Plan remains in effect.
The term "Compensation" means the amount of money reportable on the employee's
Federal Income Tax Withholding Statement, excluding overtime, shift premium,
incentive or bonus awards, allowances and reimbursements for expenses such as
relocation allowances for travel expenses, income or gains on the exercise of
Company stock options or stock appreciation rights, and similar items, whether
or not shown on the employee's Federal Income Tax Withholding Statement, but
including, in the case of salespersons, sales commissions to the extent
determined by the Board or the Committee.

     5.   Deductions.  The Company will maintain payroll deduction accounts for
          ----------
all participating employees.  With respect to any Offering made under this Plan,
an employee may authorize a payroll deduction, as set forth below, from the
Compensation he or she receives during the Plan Period or such shorter period
during which deductions from payroll are made.  Payroll deductions may be at the
rate of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9% or 10% of Compensation with any
change in compensation during the Plan Period to result in an automatic
corresponding change in the dollar amount withheld.

     No employee may be granted an Option (as defined in Section 9) which
permits his rights to purchase Common Stock under this Plan and any other
employee stock purchase plan (as defined in Section 423(b) of the Code) of the
Company and its

                                      -2-
<PAGE>

subsidiaries, to accrue at a rate which exceeds $25,000 of the fair market value
of such Common Stock (determined at the Offering Commencement Date of the Plan
Period) for each calendar year in which the Option is outstanding at any time.

     6.   Deduction Changes.  An employee may decrease or discontinue his
          -----------------
payroll deduction once during any Plan Period, by filing a new payroll deduction
authorization form.  However, an employee may not increase his payroll deduction
during a Plan Period.  If an employee elects to discontinue his payroll
deductions during a Plan Period, but does not elect to withdraw his funds
pursuant to Section 8 hereof, funds deducted prior to his election to
discontinue will be applied to the purchase of Common Stock on the Exercise Date
(as defined below).

     7.   Interest.  Interest will not be paid on any employee accounts, except
          --------
to the extent that the Board or the Committee, in its sole discretion, elects to
credit employee accounts with interest at such per annum rate as it may from
time to time determine.

     8.   Withdrawal of Funds.  An employee may at any time prior to the close
          -------------------
of business on the last business day in a Plan Period and for any reason
permanently draw out the balance accumulated in the employee's account and
thereby withdraw from participation in an Offering.  Partial withdrawals are not
permitted.  The employee may not begin participation again during the remainder
of the Plan Period.  The employee may participate in any subsequent Offering in
accordance with terms and conditions established by the Board or the Committee.

     9.   Purchase of Shares.  On the Offering Commencement Date of each Plan
          ------------------
Period, the Company will grant to each eligible employee who is then a
participant in the Plan an option ("Option") to purchase on the last business
day of such Plan Period (the "Exercise Date"), at the Option Price hereinafter
provided for, the largest number of whole shares of Common Stock of the Company
as does not exceed the number of shares determined by multiplying $2,083 by the
number of full months in the Offering Period and dividing the result by the
closing price (as defined below) on the Offering Commencement Date of such Plan
Period.

     The purchase price for each share purchased will be 85% of the closing
price of the Common Stock on (i) the first business day of such Plan Period or
(ii) the Exercise Date, whichever closing price shall be less.  Such closing
price shall be (a) the closing price on any national securities exchange on
which the Common Stock is listed, (b) the closing price of the Common Stock on
the Nasdaq National Market or (c) the average of the closing bid and asked
prices in the over-the-counter-market, whichever is applicable, as published in
The Wall Street Journal; provided, that, with respect to the first Plan Period,

the closing price on the Offering Commencement Date shall be the initial public
offering price provided for in the underwriting agreement entered into by

                                      -3-

the Company in connection with the IPO. If no sales of Common Stock were made on
such a day, the price of the Common Stock for purposes of clauses (a) and (b)
above shall be the reported price for the next preceding day on which sales were
made.

     Each employee who continues to be a participant in the Plan on the Exercise
Date shall be deemed to have exercised his Option at the Option Price on such
date and shall be deemed to have purchased from the Company the number of full
shares of Common Stock reserved for the purpose of the Plan that his accumulated
payroll deductions on such date will pay for, but not in excess of the maximum
number determined in the manner set forth above.

     Any balance remaining in an employee's payroll deduction account at the end
of a Plan Period will be automatically refunded to the employee, except that any
balance which is less than the purchase price of one share of Common Stock will
be carried forward into the employee's payroll deduction account for the
following Offering, unless the employee elects not to participate in the
following Offering under the Plan, in which case the balance in the employee's
account shall be refunded.

     10.  Issuance of Certificates.  Certificates representing shares of Common
          ------------------------
Stock purchased under the Plan may be issued only in the name of the employee,
in the name of the employee and another person of legal age as joint tenants
with rights of survivorship, or (in the Company's sole discretion) in the name
of a brokerage firm, bank or other nominee holder designated by the employee.
The Company may, in its sole discretion and in compliance with applicable laws,
authorize the use of book entry registration of shares in lieu of issuing stock
certificates.

     11.  Rights on Retirement, Death or Termination of Employment.  In the
          --------------------------------------------------------
event of a participating employee's termination of employment prior to the last
business day of a Plan Period, no payroll deduction shall be taken from any pay
due and owing to an employee and the balance in the employee's account shall be
paid to the employee or, in the event of the employee's death, (a) to a
beneficiary previously designated in a revocable notice signed by the employee
(with any spousal consent required under state law) or (b) in the absence of
such a designated beneficiary, to the executor or administrator of the
employee's estate or (c) if no such executor or administrator has been appointed
to the knowledge of the Company, to such other person(s) as the Company may, in
its discretion, designate.  If, prior to the last business day of the Plan
Period, the Designated Subsidiary by which an employee is employed shall cease
to be a subsidiary of the Company, or if the employee is transferred to a
subsidiary of the Company that is not a Designated Subsidiary, the employee
shall be deemed to have terminated employment for the purposes of this Plan.

                                      -4-
<PAGE>

     12.  Optionees Not Stockholders.  Neither the granting of an Option to an
          --------------------------
employee nor the deductions from his pay shall constitute such employee a
stockholder of the shares of Common Stock covered by an Option under this Plan
until such shares have been purchased by and issued to him.

     13.  Rights Not Transferable.  Rights under this Plan are not transferable
          -----------------------
by a participating employee other than by will or the laws of descent and
distribution, and are exercisable during the employee's lifetime only by the
employee.

     14.  Application of Funds.  All funds received or held by the Company under
          --------------------
this Plan may be combined with other corporate funds and may be used for any
corporate purpose.

     15.  Adjustment in Case of Changes Affecting Common Stock.  In the event of
          ----------------------------------------------------
a subdivision of outstanding shares of Common Stock, or the payment of a
dividend in Common Stock, the number of shares approved for this Plan, and the
share limitation set forth in Section 9, shall be increased proportionately, and
such other adjustment shall be made as may be deemed equitable by the Board or
the Committee.  In the event of any other change affecting the Common Stock,
such adjustment shall be made as may be deemed equitable by the Board or the
Committee to give proper effect to such event.

     16.  Merger.  If the Company shall at any time merge or consolidate with
          ------
another corporation and the holders of the capital stock of the Company
immediately prior to such merger or consolidation continue to hold at least 80%
by voting power of the capital stock of the surviving corporation ("Continuity
of Control"), the holder of each Option then outstanding will thereafter be
entitled to receive at the next Exercise Date upon the exercise of such Option
for each share as to which such Option shall be exercised the securities or
property which a holder of one share of the Common Stock was entitled to upon
and at the time of such merger or consolidation, and the Board or the Committee
shall take such steps in connection with such merger or consolidation as the
Board or the Committee shall deem necessary to assure that the provisions of
Section 15 shall thereafter be applicable, as nearly as reasonably may be, in
relation to the said securities or property as to which such holder of such
Option might thereafter be entitled to receive thereunder.

     In the event of a merger or consolidation of the Company with or into
another corporation which does not involve Continuity of Control, or of a sale
of all or substantially all of the assets of the Company while unexercised
Options remain outstanding under the Plan, (a) subject to the provisions of
clauses (b) and (c), after the effective date of such transaction, each holder
of an outstanding Option shall be entitled, upon exercise of such Option, to
receive in lieu of shares of Common Stock, shares of such stock or other
securities as the holders of shares of Common Stock

                                      -5-
<PAGE>

received pursuant to the terms of such transaction; or (b) all outstanding
Options may be cancelled by the Board or the Committee as of a date prior to the
effective date of any such transaction and all payroll deductions shall be paid
out to the participating employees; or (c) all outstanding Options may be
cancelled by the Board or the Committee as of the effective date of any such
transaction, provided that notice of such cancellation shall be given to each
holder of an Option, and each holder of an Option shall have the right to
exercise such Option in full based on payroll deductions then credited to his
account as of a date determined by the Board or the Committee, which date shall
not be less than ten (10) days preceding the effective date of such transaction.

     17.  Amendment of the Plan.  The Board may at any time, and from time to
          ---------------------
time, amend this Plan in any respect, except that (a) if the approval of any
such amendment by the stockholders of the Company is required by Section 423 of
the Code, such amendment shall not be effected without such approval, and (b) in
no event may any amendment be made which would cause the Plan to fail to comply
with Section 423 of the Code.

     18.  Insufficient Shares.  In the event that the total number of shares of
          -------------------
Common Stock specified in elections to be purchased under any Offering plus the
number of shares purchased under previous Offerings under this Plan exceeds the
maximum number of shares issuable under this Plan, the Board or the Committee
will allot the shares then available on a pro rata basis.

     19.  Termination of the Plan.  This Plan may be terminated at any time by
          -----------------------
the Board.  Upon termination of this Plan all amounts in the accounts of
participating employees shall be promptly refunded.

     20.  Governmental Regulations.  The Company's obligation to sell and
          ------------------------
deliver Common Stock under this Plan is subject to listing on a national stock
exchange or quotation on the Nasdaq National Market (to the extent the Common
Stock is then so listed or quoted) and the approval of all governmental
authorities required in connection with the authorization, issuance or sale of
such stock.

     21.  Governing Law.  The Plan shall be governed by Delaware law except to
          -------------
the extent that such law is preempted by federal law.

     22.  Issuance of Shares.  Shares may be issued upon exercise of an Option
          ------------------
from authorized but unissued Common Stock, from shares held in the treasury of
the Company, or from any other proper source.

     23.  Notification upon Sale of Shares.  Each employee agrees, by entering
          --------------------------------
the Plan, to promptly give the Company notice of any disposition of shares
purchased

                                      -6-
<PAGE>

under the Plan where such disposition occurs within two years after the date of
grant of the Option pursuant to which such shares were purchased.

     24.  Effective Date and Approval of Shareholders.  The Plan shall take
          -------------------------------------------
effect upon the effectiveness of the Company's registration statement under the
Securities Act of 1933, as amended, relating to the Company's initial public
offering of Common Stock, subject to approval by the stockholders of the Company
as required by Section 423 of the Code, which approval must occur within twelve
months of the adoption of the Plan by the Board.

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

                         FINANCIAL REPORTING AGREEMENT

     This Financial Reporting Agreement (the "Agreement") dated as of January
28, 2000 is entered into by and among Switchboard Incorporated, a Delaware
corporation ("Switchboard"), Banyan Systems Incorporated, a Massachusetts
corporation ("Banyan"), and CBS Corporation, a Pennsylvania corporation ("CBS").

     WHEREAS, CBS and Banyan are significant stockholders in Switchboard;

     WHEREAS, each of Banyan and CBS is or may in the future be subject to
certain financial reporting obligations with respect to their respective
ownership of securities of Switchboard; and

     WHEREAS, the parties desire to memorialize their understanding regarding
the provision by Switchboard of financial information to Banyan and CBS;

     NOW, THEREFORE, for good and valuable consideration, the receipt of which
is hereby acknowledged, the parties hereto agree as follows:

          1.  Provision of Financial Statements.  Switchboard shall provide each
              ---------------------------------
of Banyan and CBS with unaudited monthly, quarterly, and annual financial
information consisting of summarized financial information as described in
Securities and Exchange Commission ("SEC") Regulation S-X, each prepared in
accordance with generally accepted accounting practices in the U.S. ("GAAP")
within 30 days following each period end. Switchboard will promptly notify each
of Banyan and CBS of any adjustment made to such financial information. In
addition, Switchboard shall provide each of Banyan and CBS with annual audited
financial statements prepared in accordance with GAAP, together with an audit
opinion from a "Big 5" public accounting firm no later than 90 days following
year end.

     If (x) Banyan or any of its affiliates and/or (y) CBS or any of its
affiliates notifies Switchboard that the party giving such notification is
required to include summarized Switchboard financial information in its
consolidated financial statements, thereafter Switchboard shall provide the
party giving such notification with (1) audited annual financial statements of
Switchboard prepared in accordance with GAAP within 75 days following year end;
and (2) reviewed quarterly financial statements of Switchboard within 40 days
following period end.

     If (x) Banyan or any of its affiliates and/or (y) CBS or any of its
affiliates notifies Switchboard that Switchboard represents an unconsolidated
subsidiary of the size to qualify as a "significant subsidiary" (as defined by
SEC Regulation S-X) at the 20% level of the party giving such notification, then
Switchboard shall provide to the party giving such notification (1) draft
audited annual financial statements within 45 days following period end; (2)
audited financial statements within 75 days following year end; (3)
<PAGE>

reviewed draft quarterly financial statements within 35 days following period
end; and (4) final quarterly financial statements within 40 days following
period end.

    2.  Provision of Additional Information.  If requested by Banyan and/or CBS,
        -----------------------------------
Switchboard shall provide the requesting party with 12 month projections, in
reasonable detail, of Switchboard's results of operations, statement of
financial position, related cash flow and expected use of CBS advertising (the
"Forecast Information") in order for the requesting party to estimate its
consolidated results of operations, including its equity earnings/(loss) in
Switchboard and its statement of financial position and for tax planning and
other similar purposes.  Banyan and/or CBS, as the case may be, agree to treat
any such Forecast Information which is provided to them as confidential and not
to use such Forecast Information for any purpose other than as set forth above.
CBS agrees that no specific Forecast Information regarding Switchboard will be
publicly disclosed in any CBS financial information without Switchboard's prior
consent.  Such Forecast Information shall be delivered in the case of a request
made by CBS to the Vice President and Controller of CBS.  The Vice President and
Controller of CBS shall only allow such Forecast Information to be reviewed and
used by those persons who need such information to estimate CBS' consolidated
financial results. Banyan agrees that no specific Forecast Information regarding
Switchboard will be publicly disclosed in any Banyan financial information
without Switchboard's prior consent.  Such Forecast Information shall be
delivered in the case of a request made by Banyan to the Chief Executive Officer
and Chief Financial Officer of Banyan.  The Chief Executive Officer and Chief
Financial Officer of Banyan shall only allow such Forecast Information to be
reviewed and used by those persons who need such information to estimate
Banyan's consolidated financial results.

    3.  General.  This Agreement may be executed in two or more counterparts,
        -------
each of which shall be deemed an original but all of which together shall
constitute one and the same instrument. This Agreement will be binding upon
Switchboard, Banyan and CBS and their respective successors and assigns. This
Agreement shall be governed by and construed in accordance with the internal
laws of the State of New York (without reference to the conflicts of law
provisions thereof). Any term of this Agreement may be amended or terminated
with written consent of each of the parties to this Agreement. Any term of this
Agreement may be waived (either generally or in a particular instance and either
retroactively or prospectively) with written consent of each of the parties to
this Agreement that is affected by such waiver.

                          DATABASE LICENSE AGREEMENT

     This AGREEMENT made and entered into as of December 31, 1997 (the
"Effective Date") by and between American Business Information, Inc.(R) ("ABI"),
a Delaware corporation, and Switchboard Incorporated ("LICENSEE"), a Delaware
corporation.

     WHEREAS, ABI owns a proprietary database as defined in paragraph 1 of this
AGREEMENT containing information on businesses and individuals in the United
States and desires to license this database on the terms provided in this
AGREEMENT.

WHEREAS, the LICENSEE desires to license ABI's database on the terms provided in
this Agreement.

     Now therefore the parties mutually agree as follows:

1.   DEFINITIONS.
     -----------

1.1  ABI DATABASE refers to:

          a) a national database of approximately 10 million businesses in the
          United States with data elements described in APPENDIX A, Attachment A
          and any additional data elements which may be added from time to time
          at ABI's sole discretion; and

          b) a national database of approximately 115,000,000 individuals in the
          United States with data elements described in APPENDIX A, Attachment B
          and any additional data elements which may be added from time to time
          at ABI's sole discretion.

1.2 USER refers to any company, organization or individual which has access to
    the SERVICE for its own internal use through LICENSEE under the terms of
    this AGREEMENT.

1.3 LICENSE FEES refers to the fees due ABI for the use of the ABI DATABASE as
    provided in paragraph 3 below, and fully described in APPENDIX B.

1.4 SERVICE refers to:

          a) LICENSEE's internet-based directory service known as Switchboard,
          which includes a free business and residential telephone look-up
          SERVICE for USERS, including as such services may be accessed through
          or from any third party web site or interfaces, co-branded or
          otherwise which will display information from the ABI DATABASE
          pursuant to the terms of this Agreement. In the event that any third
          party web site or interface is constructed in partnership with
          Switchboard, the web site or

                                       1
<PAGE>

 Confidential Materials omitted and filed separately with the Securities and
                             Exchange Commission.
                          Asterisks denote omissions

          interface shall include Switchboard brand identification. USERS may
          search the ABI DATABASE through the SERVICE by business name or
          business category within a state, city, zip code or local proximity.
          In addition, business name searches can be conducted on a nationwide
          basis. Nationwide business name searches are subject to the further
          restrictions as outlined in APPENDIX D section D1.1B. Business search
          results may show up to, but not exceed [**] search results per screen.
          Users may search the ABI DATABASE through the SERVICE by individual
          name within the United States, state, city, zip code. Individual
          search results may show up to, but not exceed [**] listings per
          screen. In the event LICENSEE's competitors show more than [**]
          listings per screen and, in LICENSEE's sole discretion, this becomes a
          competitive threat to LICENSEE, ABI agrees to work with LICENSEE to
          relax this restriction to eliminate the competitive threat.

          b) SERVICE also includes additional enhanced SERVICES which may be
          developed by LICENSEE allowing access to information in the ABI
          DATABASE through data access mechanisms, including but not limited to
          Lightweight Directory Assistance and Protocol Directory Assistance, as
          well as Intranet Directory Assistance for corporate USERS subject to
          the terms outlined in paragraph 2.2 herein.

2.  LICENSE.
    -------

2.1 Subject to the terms and conditions of this AGREEMENT, ABI grants the
    LICENSEE a limited non-exclusive, non-transferable license during the term
    of this AGREEMENT to incorporate the ABI DATABASE into the SERVICE in the
    manner described in paragraph 1.4.a. above and to allow USERS to access the
    ABI DATABASE through the SERVICE for USERS' internal purposes only.

    In the event that LICENSEE develops additional SERVICES as described in
    paragraph 1.4.b. above, Switchboard shall compensate ABI for additional use
    of the ABI DATABASE by

          a) paying ABI [**] of the "net revenue" derived by Switchboard from
          such additional Services which return results from the ABI Database of
          individuals pursuant to Section 1.1b and

          b) payments to be mutually agreed upon from such additional services
          which return results from the ABI Database of businesses pursuant to
          Section 1.1a.

    For the purposes of the preceding sentences, "net revenue" shall mean
    Switchboard's revenue from such additional Services less any commissions,
    fees, revenue splits, uncollectable accounts receivables, and applicable
    sales and use taxes in connection therewith.

                                       2
<PAGE>

2.2  Any use of the ABI DATABASE not expressly authorized in this AGREEMENT is
     strictly prohibited. Without limiting the generality of the foregoing,
     LICENSEE and the USERS are expressly prohibited from (i) sublicensing or
     reselling the ABI DATABASE; (ii) [NOTE: THIS COVERED IN SECTION 2.6] using
     the ABI DATABASE, in any PRODUCT or SERVICE, or offering it through any
     third party, other than as specifically authorized in this AGREEMENT; or
     (iii) disassembling, decompiling, reverse engineering, modifying or
     otherwise altering the ABI DATABASE, except as required to provide the
     SERVICE, or any part thereof without ABI's prior written consent, such
     consent may be withheld in ABI's sole discretion.

2.3  LICENSEE acknowledges that any unauthorized use of the ABI DATABASE may
     cause irreparable harm and injury to ABI for which there is no adequate
     remedy at law. In addition to all other remedies available under this
     AGREEMENT, at law or in equity, LICENSEE further agrees that ABI shall be
     entitled to seek injunctive relief in the event LICENSEE uses the ABI
     DATABASE in violation of the limited license granted hereunder and fails to
     cure within thirty (30) days after notice of such violation from ABI.

2.4  LICENSEE agrees to provide appropriate legal notices relevant to the ABI
     DATABASE on the SERVICE as reasonably requested by ABI to protect its
     rights therein including: "Data provided by American Business Information,
     Inc.(R), Omaha, Nebraska, Copyright (C) 1997 All Rights Reserved", and as
     further described in APPENDIX C. The LICENSEE must receive ABI's prior
     written approval to use any ABI logo, trademark, service mark or trade name
     except as mandated in this AGREEMENT.

2.5  LICENSEE shall maintain a system of controls set forth in Appendix D which
     are designed to:

          (a) Protect the integrity of the ABI DATABASE;

          (b) Control access to the ABI DATABASE;

          (c) Prevent unauthorized usage of the ABI DATABASE; and

          (d) Reasonably ensure that the amount of usage of the ABI DATABASE is
              accurately recorded.

2.6  LICENSEE shall:

          (a) House the ABI DATABASE on the Internet behind firewalls necessary
              to prevent unauthorized usage of the ABI DATABASE.

          (b) Allow ABI access to its computers, software, and technicians as
              reasonably necessary and upon reasonable prior notice to insure
              and confirm that the security designed to prevent unauthorized
              usage of the ABI DATABASE by Internet Users is adequate.
              Unauthorized usage shall be defined to include any downloading or
              printing of the ABI DATABASE in whole or in part (except as to
              printing of single listings or listings up to the number stated in
              Appendix D)

                                       3
<PAGE>

               and any other use which is either expressly prohibited by this
               AGREEMENT or not specifically authorized under this AGREEMENT.

          (c)  Include a policy statement on the LICENSEE's SERVICE which states
               that USERS may not use the ABI DATABASE for the purpose of
               compiling, enhancing, verifying, or modifying in any way any
               mailing list, directory, or other compilation of information

                    SWITCHBOARD INC. DATA MINING PROTECTION
                    ---------------------------------------

D.1.1 LICENSEE agrees to incorporate the following protection measures in
connection with the SERVICE to prevent unauthorized downloading of mailing
information which may harm ABI's business:

      A) Each query to the SERVICE shall be broken into a number of
      client/server requests. Only a small number of names will be returned per
      request to the SERVICE (for example, 8). This shall require repeated calls
      to be made to the SERVICE, which slows automated programs down and make
      detection of a violation easier.

      B) There will be an upper limit on the number of names returned from a
      single unmodified query ([**] on residential,[**] on business). Secure
      encryption keys with download limits will be issued by the service and
      attached to each request to the SERVICE to enforce this limit. The use of
      such keys will not require any special action on the part of the USER.
      Certain businesses categories will be subject to a further restriction of
      [**] records returned. ABI and LICENSEE shall work together to agree upon
      the further restricted categories. The parties have already agreed that
      Nationwide business name searches will be subject to the [**] record
      restriction.

      C) SERVICE logs will be continuously generated and will be reviewed
      manually or programmatically on a regular basis to look for patterns of
      abuse, particularly multiple queries from a single address. LICENSEE
      expects to build log analysis tools that can run automatically and flag
      potential violations based upon criteria such as frequency of queries from
      individual addresses.

      D) LICENSEE agrees to work with ABI in good faith throughout the term of
      the Agreement to prevent abuse by users attempting to collect names for
      the purposes of creating mailing lists, and agrees to implement mutually
      agreed upon additional safeguards to prevent such abuse.

                                   ----------
                         ABI DATABASE QUALITY STANDARDS
                         ------------------------------

Switchboard will regularly review the quality of the ABI Database as delivered
to Switchboard during the Term of this Agreement. The method for this review is
described below.

1. Switchboard will spot check the ABI Database monthly with each delivery.
Approximately 300 Switchboard members, and approximately 200 businesses will be
chosen at random from a base of approximately 1 million. Members chosen will
have supplied Switchboard with their current address and phone number
information some time within the previous 18 months.

2. Switchboard will use a "reverse lookup" technique to verify the information
in the ABI Database. Using a software tool, Switchboard will input the phone
number in a query and analyze the resulting information for that phone number
from the ABI Database. The results will be scored according to partial and
complete matches.

3. Starting with the third month of this Agreement, if the score negatively
deviates more than 15% in any given month from the average score for all
previous months, Switchboard will do a more comprehensive test on the ABI
Database, using the same technique but with a substantially larger sample size.

4. If the score on the subsequent test negatively deviates more than 15% from
the average score from all previous months, then Switchboard shall notify ABI in
writing of the suspected deficiency in the ABI Database quality.

5. ABI agrees to quickly work with Switchboard to identify the source of the
deficiency and agrees to correct the problem, if one exists, with a new delivery
of the ABI Database within thirty (30) days.

6. If the deficiency cannot be corrected within thirty (30) days, and a mutually
agreeable solution cannot be identified, Switchboard shall have the right to
terminate this Agreement with sixty (60) days written notice to ABI.

7)  Paragraph 4.2 is amended and replaced in its entirety as follows:

          "INFOUSA will supply LICENSEE with a monthly updated full-file to the

          file to the residential portion of the INFOUSA DATABASE (the "White
          Pages File") described in Attachment B to APPENDIX A throughout the

          new adds, changes and deletes, INFOUSA shall deliver such monthly
          updates in such requested transaction-file form, provided that such

          delivery of any updated file pursuant to this Section 4.2, the
          delivered portion of the INFOUSA DATABASE shall be as complete and
          accurate as that made available by INFOUSA to its own users or other

          Appendix B or any provision of Appendix F, in each case as amended by
          this Amendment Number One, the other party shall have a right to
          terminate only that portion of the AGREEMENT which relates to LIST
          EXPRESS products, which shall be deemed to be only the provisions
          referenced in this sentence. Breach of such stated provisions shall in
          no event be cause for termination of the AGREEMENT. Termination of the
          LIST EXPRESS portion of the AGREEMENT shall take effect only after the
          non-breaching party provides the breaching party with thirty (30) days
          prior written notice of such breach and the breaching party fails to
          remedy such breach within such notice period."

Licensee shall pay to infoUSA CPM Royalties as follows:

2)   MINIMUM CPM ROYALTIES AND CAP: If the CPM Royalties otherwise payable
     pursuant to Section 1 are less than the applicable Annual Minimum Royalties
     set forth in this Paragraph, Licensee shall be obligated to pay the
     applicable Annual Minimum Royalties. If the CPM Royalties otherwise payable
     pursuant to Section 1 are more than the applicable Annual Minimum
     Royalties, then Licensee shall pay the CPM Royalties as calculated pursuant
     to Section 1, but only up to, and not exceeding, the applicable Annual Cap
     set forth in this Paragraph.

3) PAYMENT OF CPM ROYALTIES. Licensee shall pay infoUSA the CPM Royalties in
accordance with sections 1 and 2 of this Appendix B, as follows:

     Licensee shall pay the Annual Minimum Royalties in the Quarterly Minimum
     Payments as set forth in Section 2. Except for the first Quarterly Minimum
     Payment, which shall be payable within thirty (30) days after the Renewal
     Effective Date, Licensee shall pay each Quarterly Minimum Payment prior to
     the last day of the previous calendar quarter, provided that (a) infoUSA
     has delivered the initial INFOUSA DATABASE or all monthly updates for the
     quarter, as applicable, to Licensee pursuant to Section 4; and (b) infoUSA
     shall have invoiced Licensee for such payments at least thirty (30) days
     prior to the end of such previous calendar quarter. If infoUSA has not
     delivered all monthly updates or any invoice by such time, Licensee's
     payment obligation shall be deferred until fifteen (15) days after all such
     monthly updates for the quarter and the invoice have been delivered. Within
     thirty (30) days after the end of each one-year period of this Agreement,
     Licensee shall pay infoUSA the difference, if any, between the CPM
     Royalties payable pursuant to Section 1 of this Appendix B, and the Annual
     Minimum Royalties paid by Licensee applicable to such one-year period. In
     no event shall Licensee be obligated to pay any amount exceeding the Annual
     Cap for any one-year period or any other license or other fees not
     expressly set forth in this Appendix B.

4)   REPORTING: Within thirty (30) days following the close of each month during
     the term of this Agreement, Licensee will supply infoUSA with a CPM Report
     setting forth the number of Pages viewed by Users, the breakdown between
     Pages on the Service and those displayed through Wireless and XML
     Applications, and the applicable CPM rate applied pursuant to Section 1(a)
     of this Appendix B.

5)   UPDATES: There will be no additional fee for the monthly updates of the
     infoUSA Database. In the event infoUSA offers updates of the infoUSA
     Database on a more frequent basis than monthly to any other licensees,
     whether via electronic means or otherwise, infoUSA shall notify Licensee,
     and Licensee may elect to receive updates with the same frequency and/or in
     the same electronic format offered to such other licensees.

6)   BUTTONS REVENUE SHARE DUE TO LICENSEE: infoUSA will pay Licensee on a
     quarterly basis, a royalty equal to [**] of Net Revenues from sales to
     Users who accessed infoUSA's web site through the Buttons (described in
     Appendix F).

     "Net Revenue" means the amounts collected by infoUSA from such sales, less
     any third-party commissions or fees applicable to such sales. infoUSA will
     report quarterly to Licensee showing the Net Revenue and applicable third
     party commissions or fees in reasonably sufficient detail to allow
     verification of the calculation thereof.

7)   AUDIT: Each party hereto shall permit the other party, through an
     independent certified public accountant reasonably acceptable to the
     audited party, to audit its accounts, books and records, as they relate to
     the audited party's obligation to make payments hereunder (or, in the case
     of the Licensee, as they relate specifically to the number of co-branding
     relationships of Licensee). Such audits shall be at the expense of the
     auditing party and shall be made only upon reasonable notice. The right
     granted under this Section shall exist during the term of this Agreement
     and for one year thereafter. Upon concluding any audit, the auditing shall
     notify the other party of the results thereof. In the event that the
     auditing party notifies the other that an adjustment must be made to the
     royalties or payments previously paid by such audited party hereunder, the
     parties shall use their best efforts in good faith to agree upon the amount
     of any such adjustment. Any such adjustment shall be paid within 5 business
     days after such agreement is reached. In the event the parties agree that
     the total amount of royalties or payments previously paid was less than the
     amount required to be paid under this Agreement and such deficiency is 10%
     or more of the amount previously paid, the audited party shall pay the
     reasonable and actual audit costs incurred by the auditing party.

8)   ADDRESS BOOK ROYALTIES: In connection with Address Book features set forth
     in Section C.1.f.(iii) of Appendix C, (in which more than [**] Listings

     infoUSA an additional [**] per thousand) on CPM Royalties attributable to

     third party Co-Branded Sites or Wireless or XML Applications.

                          INTERNET PROVIDER AGREEMENT

                            AGREEMENT NO. IP-96-007

ARTICLE 1: PARTIES, BACKGROUND AND DEFINITIONS

     1.1  Parties to Agreement. This Internet Provider Agreement (the
          --------------------
"Agreement") is entered into by and between Etak, Inc., a California corporation
("Etak") and Lucent Technologies Inc., a Delaware corporation ("Lucent").

     1.2  Background.  Etak develops and distributes digital geographic data,
          ----------
geographic access software, navigation products, geocoding services, and related
materials.  Lucent wishes to obtain from Etak the Licensed Products listed on
Exhibit A so that Lucent can create Derivative Products that are used to provide
Geographic Services to End Users via the Internet as further set forth in
Article 2.  Defined terms used in this Agreement are set forth in Section 11.1.

ARTICLE 2: APPOINTMENT OF LUCENT AND GRANT OF LICENSE

     2.1  Appointment. Etak hereby appoints Lucent, on a non-exclusive basis,
          -----------
and Lucent accepts such appointment, as an authorized Etak Internet Provider.

     2.2  Grant of Development License.  Etak hereby grants to Lucent a non-
          ----------------------------
exclusive, non-transferable, license to use each Licensed Product in object-code
form for the limited purpose of in-house development by Lucent of (i) Derivative
Products and (ii) Geographic Services on the Internet using those Derivative
Products.

     2.3  Grant of Right to Provide Geographic Services on the Internet. Etak
          -------------------------------------------------------------
hereby grants to Lucent the non-exclusive, non-transferable right to use the
Derivative Products to provide Geographic Services on the Internet to End Users,
provided that (i) Lucent has paid to Etak all fees due in accordance with
Exhibit A; and (ii) Lucent continues to comply with all provisions of this
Agreement.

     2.4  Permitted Geographic Services.  Lucent is permitted to provide the
          -----------------------------
following Geographic Service to End Users via the Internet, subject to the
following restrictions:

          (a)  Three Classes of Geographic Services.
               ------------------------------------

               (1)  "Maps On Us" WWW Site. Lucent is authorized to operate the
                    ---------------------
"Maps on Us" World Wide Web site to provide Map Images (as defined below in
section 2.4(b)) and Route Guidance (as defined below) to End Users. "Route
Guidance" means providing text-based or bit-map graphical directions regarding
how to travel from Point A to Point B in response to an End User inquiry for
such information, but does not include requests or instructions for more than
[**] endpoints [**] per request or more than [**] intermediate points per
request. The Maps On Us World Wide Web site shall be marketed and provided (i)
directly on behalf of Lucent and not on behalf of or by any third party, and
(ii) only under trade names and trademarks owned and controlled directly by
Lucent (except that Lucent shall include Etak's copyright notice and license
agreement link in accordance with section 2.4(b)(4)).

 Confidential Materials omitted and filed separately with the Securities and
                             Exchange Commission.
                          Asterisks denote omissions.

               (2)  "Maps On Us" Internet Service. Lucent is authorized to
                    -----------------------------
     operate the "Maps on Us" Internet Service by which Lucent will provide a
     linked Internet service to a third party (the "Lucent Customer") with its
     own World Wide Web site so that End Users of the Lucent Customer's World
     Wide Web site can obtain Map Images and Route Guidance pertinent to the
     information contained on the Lucent Customer's World Wide Web site. Unlike
     the Maps On Us WWW Site, the Maps On Us Internet Service may be marketed
     and provided so that Lucent is invisible to the End User and is offered
     under the trade names and trademarks of the Lucent Customer, provided,
     however, that all other restrictions and conditions set forth in this
     Agreement are met.

               (3)  "Maps On Us" Intranet Service. Lucent is authorized to
                    -----------------------------
     operate the "Maps on Us" Intranet Service with the same scope of services
     as permitted above with respect to the Maps On Us World Wide Web Site, with
     the following distinction: the only End Users who shall be permitted to
     obtain access to the Maps on Us Intranet Service are those who have been
     granted a password by Lucent to access the Intranet Service, and Lucent
     shall retrieve and retain an audit trail showing each hit when a particular
     End User is using the Service, the particular End User using the Service,
     and what type and level of Service that End User is accessing as defined in
     section B3 of Exhibit A.

          (b)  Restrictions Applicable to all Classes of Geographic Services.
               -------------------------------------------------------------
               (1)  The Geographic Services shall be provided via
     telecommunications connection to the Internet, by means of a World Wide Web
     site owned and controlled by Lucent, the site server for which is located
     at a geographic location controlled by Lucent.

               (2)  Products shall not be disclosed, disseminated or distributed
     in digital form to any third party, including without limitation any End
     User or Lucent Customer. Products in digital form shall be used only on
     Lucent's own in-house server and not anywhere else or by anyone else.

               (3)  The Geographic Services shall consist of bit-mapped (raster)
     graphics images derived from the Products ("Map Images") and standard
     English text derived from the Products. In order to minimize data transfer
     time, Lucent is permitted to utilize Java Applets or Plug-in Mechanisms to
     provide the Geographic Services to the End User and Lucent Customer in
     digital, vector-based form. However, such digital form shall be invisible
     to and unusable by the End User and Lucent Customer. The End User and
     Lucent Customer shall be able to access, utilize and store the Map Images
     in bit-mapped (raster) graphic form, and in no other form. Lucent shall not
     authorize or enable the End User or Lucent Customer to download or access
     the Map Images or the Products in any form except as expressly authorized
     in this paragraph. Except as expressly permitted above in this section 2.4,
     Lucent shall not distribute, disclose, or market the Map Images or Products
     in any vector-based or digital form. Lucent may allow the Map Images to be
     rotated or zoomed by the End User's entering a manual keystroke for each
     such movement or rotation. A single Map Image shall not contain more than
     [**] "Features" derived from Etak's original digital Licensed Product. A
     "Feature" is defined as a one-cell as denoted in Etak's database. The Map
     Images may include icons added by Lucent representing the location of
     points, lines and areas of interest. End Users may be permitted to download
     more than one selected Image Map at a time, provided that all Map Images
     together do

                                       2

 Confidential Materials omitted and filed separately with the Securities and

                          Asterisks denote omissions.

     not contain more than [**] Features; however, if the screen consists of an
     Etak U.S. small scale Map Image or a portion thereof, plus an inset large-
     scale map or maps showing details of an area or areas of interest from
     within the bounds of the small scale Map Image, then only the Features
     contained in the inset large-scale Map Image(s) shall be counted towards
     the limit of [**] total Features. In no event shall End Users be
     authorized, enabled or permitted to download, access, utilize or store the
     Products or Map Images in any form except as expressly authorized above in
     this section 2.4.

               (4)  Lucent shall include an initial screen that must necessarily
     and unavoidably be viewed by each user that contains the following notice
     in conspicuous type: "Copyright Etak, Inc. 1984-1996. All Rights Reserved.
     By using this site, you agree to the attached LICENSE AGREEMENT." The term
                                                   -----------------
     LICENSE AGREEMENT shall, when clicked on, hot link to a page containing the
     -----------------
     full, unaltered text of the End User Internet License Agreement attached
     hereto as Exhibit B. In the same location Lucent shall also include a
     conspicuous disclaimer stating "Routes and road conditions may change and
     may not be accurately reflected in all cases. Please pay attention at all
     times to road conditions, routes, and street signs and other posted
     directional information."

               Each Map Image displayed shall conspicuously include the
     following notice: "Copyright Etak, Inc. 1984-1996. All Rights Reserved. Use
     Subject to LICENSE." The term LICENSE shall, when clicked on, hot link to a
                -------            -------
     page containing the full, unaltered text of the End User Internet License
     Agreement attached hereto as Exhibit B. If it is not technically possible
     to include the "LICENSE" hot link within the Map Image itself, then the Map
     Image may include the notice as ordinary text, provided that the hot link
     is placed immediately adjacent to the Map Image.

               Lucent shall submit Lucent's web page designs to Etak for Etak's
     review and approval as being compliant with this section 2.4 before Lucent
     utilizes any such designs. Lucent may submit a web page template to Etak
     that Etak approves and a new web page design need not be submitted to Etak
     if the notices as required by this section are included in the same manner
     as Etak previously approved in the template. Etak agrees to review and
     respond to Lucent's submission of a web page design within ten (10) working
     days of the date of receipt by Etak.

             2.5 Ownership. This Agreement does not constitute a transfer of any
                 ---------
     title or interest in the Licensed Products, and Etak reserves all rights in
     the Licensed Products not expressly granted to Lucent by this Agreement.
     Any portion of the Licensed Products that is modified or merged into other
     computer programs or data by Lucent, or is combined with other programs or
     data to form Derivative Products, shall continue to be subject to the
     provisions of this Agreement, and Etak retains ownership of all such
     Licensed Products and all such portions. However, Lucent shall be owner of
     any item which Lucent can show through contemporaneous, tangible evidence
     to be a Lucent Product. Nothing in this Agreement shall be construed as, or
     deemed to be, an express or implied license for Lucent to obtain or utilize
     any of Etak's patents, copyrights, trade secrets, or other intellectual
     property, except for the limited license with respect to Etak's copyrights
     and trade secrets for Etak's software and data expressly granted under the
     terms and conditions set forth in this Article 2.

              2.6 Authorized Purpose. Lucent shall not use the Products for any
                  ------------------
     purpose except as
                                       3

          through any means other than manual entry by the user of each request
          for geographic information); provided, however, that Lucent shall be
          permitted to utilize batch geocoding for Lucent's internal use only,
          and shall not provide Batch Geocoding services to any third party or
          enable the Product with Batch Geocoding.

     2.7  Object Code and Data Only. This license from Etak is for data and
          -------------------------

However, if the parties agree, Etak will provide source code to Lucent for
certain software, subject to the terms and conditions of a mutually acceptable
separate agreement. In order to preserve Etak's trade secret, proprietary

portion thereof shall bear the same trademarks, logos, copyright notices and
proprietary legends as the Licensed Products which Lucent received from Etak,

adding Lucent's own copyright notice for Lucent Products).  Specifically, Lucent
shall conspicuously display Etak's copyright notice as described above in
section 2.4.

     2.9  Duplication of Products. Lucent shall not duplicate, manufacture, copy

submitted by Lucent shall be null and void, unless specifically accepted in a
writing signed by an authorized officer of Etak. Purchase orders are not valid
until accepted in writing by Etak. Shipments will be scheduled by Etak only upon
receipt of a duly executed purchase order from Lucent and upon acceptance of the
purchase order by Etak.

     3.4  Shipment Terms. All Licensed Products licensed under this Agreement
          --------------
shall be shipped F.O.B. from a facility of Etak. Lucent is responsible for all
shipping, insurance and related charges, and all risk of damage or loss to the
Licensed Products shall pass to Lucent at Etak's facility upon tender by Etak to
the carrier.

     3.5  Payment Terms. Net payment for fees and royalties due Etak from Lucent
          -------------
shall be due and payable in accordance with Exhibit A. Etak may refuse to ship,
or may delay the shipment of, any Licensed Products on order if Lucent becomes
delinquent in the payment of any of its obligations to Etak. All outstanding
amounts which are not paid when due shall bear interest at the lesser of: (i)
the maximum allowable statutory rate at the time, or (ii) 16% per annum. All
prices are net of any local, state or federal taxes, fees, assessments or other
levies, which shall be the sole obligation of Lucent. Lucent shall pay to Etak
all applicable local, state and federal taxes and levies unless Lucent has
presented to Etak a valid and appropriate certificate of exemption from those
taxes and levies.

ARTICLE 4: PROTECTION OF ETAK'S INTELLECTUAL PROPERTY

     4.1  Confidentiality of the Licensed Products. Lucent shall be the owner of
          ----------------------------------------
the storage media on which Etak delivers the Licensed Products. However, the
Licensed Products themselves, including all aspects thereof used or incorporated
in Derivative Products, together with all materials and knowledge related
thereto (the "Confidential Items"), are obtained by Lucent, and its employees,
agents and representatives, in confidence and except as expressly permitted by
this Agreement, shall not be used, duplicated or disclosed by any of them in any
form for the use or benefit of any person or entity, nor reproduced,
transcribed, imitated or

                                       5
<PAGE>

simulated in whole or in part, except for distribution in Map Image form or text
for Route Guidance to End Users via the Internet subject to the restrictions set
forth in Article 2. Lucent may disclose relevant aspects of the Confidential
Items to its employees, agents or representatives with a need to know who have
been advised that the Confidential Items are proprietary and confidential, and
who have previously or contemporaneously signed a nondisclosure agreement with
Lucent that is consistent with the standard Lucent Employee Intellectual
Property Agreement attached hereto as Exhibit C. Lucent shall protect and
preserve the confidentiality of the Licensed Products in accordance with
Lucent's standard policies applicable to Lucent's own confidential information
of an equivalent level of security, but in no event with less than reasonable
care.

     4.2  Duty to Assist. Lucent shall notify Etak promptly if Lucent has
          --------------
knowledge of any misappropriation of the Products or use of the Products by
anyone in any manner not expressly authorized by this Agreement, and shall
cooperate with any efforts by Etak to prevent any misappropriation or misuse of
the Products. The foregoing sentence does not obligate Lucent to conduct an
investigation of suspected misappropriation. In the event of any violation or
suspected violation of any provisions of this Article 4, Lucent shall promptly
notify Etak and shall, at Etak's expense, assist Etak in Etak's enforcement of
Article 4 against any current or former employee, agent or representative of
Lucent or any End User.

ARTICLE 5: WARRANTIES AND DISCLAIMER THEREOF

     5.1  Limited Warranty By Etak.
          ------------------------

          (a)  Etak warrants to Lucent that the Software Licensed Products will,
for ninety (90) days from the date of initial delivery, and that the Data
Licensed Products will, for one (1) year from the date of initial delivery,
substantially conform to the contemporaneous specifications contained in Etak's
Documentation, when used in an Etak-approved operating environment; and that the
media (if any) on which Etak delivers the Licensed Products to Lucent will be
free of manufacturing defects on the date of initial delivery.

          (b)  Lucent acknowledges that the Licensed Products are complex and
may contain some nonconformities, defects or errors. Etak does not warrant that
the Licensed Products will meet Lucent's needs or expectations, that operations
of the Licensed Products will be error free or uninterrupted, or that all the
nonconformities can or will be corrected. Lucent must notify Etak in writing
within the applicable warranty period set forth above of any claim that the
Licensed Products do not meet this Limited Warranty. Etak's SOLE OBLIGATION and
Lucent's SOLE REMEDY under this Limited Warranty is for Etak to use reasonable
efforts to repair or replace the Licensed Products or to provide an avoidance
procedure at Etak's expense within a commercially reasonable time so that the
Licensed Products substantially conform to the specifications contained in the
Documentation, or at Etak's option, to refund the royalties previously paid by
Lucent for the units of Licensed Products involved. If Lucent is unable to
describe the claimed nonconformity with sufficient specificity to enable Etak to
confirm it, then no nonconformity shall be deemed to exist.

          (c)  If the media delivered to Lucent by Etak containing the Licensed
Products possess manufacturing defects, upon notice from Lucent, Etak will
provide Lucent with a replacement copy of the Licensed Products, and Lucent
shall return to Etak the defective copy.

                                       6
<PAGE>

Etak's policy is to use virus-checking software on the Licensed Products before
they are shipped; however, because virus-checking software is not one hundred
percent reliable, Etak cannot and does not warrant that the Licensed Products
will be free from all viruses. Accordingly, Lucent should run its own virus-
checking software on the Licensed Products before loading them. If Lucent
discovers a virus on a Licensed Product as delivered by Etak that Lucent cannot
remove, Etak shall make another delivery of that Licensed Product to Lucent upon
Lucent's return of the first delivery. Etak agrees not to intentionally insert
into the Licensed Products any malicious code, program or other internal
component (e.g. computer virus, computer worm, computer time bomb, or similar
component) which is designed to damage, destroy or alter software or data.

     (d) Etak agrees that Etak's pricing to Lucent will be consistent with
applicable trade regulations.

     (e) This warranty shall not apply to any nonconformities arising from
Lucent's modification or attempted modification of the Licensed Products. If,
upon Lucent's request, Etak chooses to correct nonconformities resulting from
Lucent's modification of the Licensed Products, Lucent shall be charged for and
agrees to pay for custom programming at Etak's then current standard hourly
rate.

     (f) This Limited Warranty is void if any nonconformity has resulted from
accident, abuse, misuse, or misapplication. This Limited Warranty is for
Lucent's exclusive benefit and is non-transferable, and Lucent agrees that this
Limited Warranty fulfills its essential purpose.

     (g) THE EXPRESS WARRANTY PROVIDED IN SECTIONS 5.1(a) THROUGH (f) IS A
LIMITED WARRANTY AND IT IS THE ONLY WARRANTY MADE BY ETAK. ETAK MAKES AND LUCENT
RECEIVES NO OTHER WARRANTY, WHETHER EXPRESS OR IMPLIED, AND ALL WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR ANY PARTICULAR PURPOSE ARE EXPRESSLY EXCLUDED.
THE STATED EXPRESS WARRANTY IS THE EXCLUSIVE REMEDY FOR DAMAGES AND IS IN LIEU
OF ALL LIABILITIES OR OBLIGATIONS OF ETAK. NO ORAL OR WRITTEN ADVICE OR
INFORMATION PROVIDED BY ETAK OR ANY OF ITS AGENTS OR EMPLOYEES SHALL CREATE A
WARRANTY OR IN ANY WAY INCREASE THE SCOPE OF THIS LIMITED WARRANTY, AND LUCENT
IS NOT ENTITLED TO RELY ON ANY SUCH ADVICE OR INFORMATION.

     5.2  Lucent Express Warranty. Lucent represents and warrants that it
          -----------------------
possesses the financial resources, technical facilities and skill, and other
requirements necessary for its timely and full performance pursuant to the terms
and conditions of this Agreement, and that it is an experienced and
knowledgeable user and distributor of computer software and data.

ARTICLE 6: INDEMNIFICATION

     6.1  Indemnification by Etak.
          -----------------------

          (a)  Lucent shall notify Etak promptly upon learning of any threatened
or asserted claim that the Licensed Products infringe any patents, copyrights,
trade secrets or other intellectual property rights of any third party. Etak
shall have the sole right to control the

                                       7
<PAGE>

defense and negotiation of all such claims with respect to the Licensed Products
as originally delivered to Lucent or as incorporated within the Derivative
Products, and Lucent shall fully cooperate in Etak's defense of all such claims
at Etak's expense.

          (b)  Etak shall protect, defend (or in Etak's discretion, settle),
indemnify and hold Lucent harmless from any and all claims, demands,
liabilities, obligations, damages, suits, judgments or settlements
(collectively, "Claims"), including reasonable costs and attorneys' fees, that
are asserted against Lucent to the extent that such Claims are based upon a
contention that the Licensed Products used within the scope of this Agreement
infringe any patents, copyrights, trade secrets or other intellectual property
rights of any third party created by United States federal law, the law of any
of the United States, or the law of any nation that is a signatory to the Berne
Convention or the General Agreement on Tariffs and Trade, provided that Lucent
notified Etak in writing of such claim in sufficient time to enable Etak to
fully protect its interests without prejudice.

          (c)  If, as a result of any claim of infringement described in this
Section 6.1, Etak reasonably believes that an injunction or temporary
restraining order or such a claim is likely, Etak may in its sole discretion and
at its expense procure the right for Lucent to continue to use said Licensed
Product, or replace or modify the Licensed Product so as to make it non-
infringing. If, as a result of any claim of infringement described in this
Section 6.1, a temporary restraining order or injunction is issued prohibiting
Etak from licensing or sublicensing any Licensed Product, or prohibiting Lucent
from using any Licensed Product, Etak may in its sole discretion and at its
expense procure the right for Lucent to continue to use said Licensed Product,
replace or modify the Licensed Product so as to make it non-infringing, or if
the above options are not available to Etak on a commercially reasonable basis,
terminate this Agreement and refund the unamortized portion of the license fees
and royalties previously paid by Lucent for the use of the affected units said
Licensed Product. Calculation of the unamortized portion of the license fees
royalties shall be based upon five (5) years' straight line depreciation.

          (d)  Etak shall not have any liability under this Article 6 to the
extent that such a claim of infringement is based upon the use of the Licensed
Products in combination with other products not furnished or made by Etak (other
than a claim based upon the combination of the Licensed Products with operating
software that Etak lists as compatible with the Licensed Products), the use of
the Licensed Products in practicing any infringing process, the modification of
the Licensed Products or any portion thereof by anyone other than Etak, or
application or for the use Licensed Products in a manner for which they were not
designed or specified by Etak.

          (e)  Sections 6.1(a) through 6.1(e) state the entire and exclusive
obligation of Etak to Lucent or Lucent's End User for any claim of infringement
relating to the Licensed Products.

     6.2  Indemnification by Lucent. Lucent shall protect, defend, indemnify and
          -------------------------
hold Etak harmless from any and all claims, demands, liabilities, obligations,
damages, suits, judgments or settlements (collectively, "Claims"), including
reasonable costs and attorneys' fees, that arise from the act, neglect, omission
or unperformed obligation of Lucent in the development, modification, use or
distribution of the Derivative Products or Lucent Products or Lucent's breach of
any provision of this Agreement.

ARTICLE 7: LIMITATION ON LIABILITY

     IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR ANY CLAIM OR LOSS INCURRED BY
THE OTHER PARTY (INCLUDING WITHOUT LIMITATION COMPENSATORY, INCIDENTAL, DIRECT,
INDIRECT, SPECIAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES, LOST PROFITS,
EXPENDITURES, LOSS OF GOODWILL, OR DAMAGES RESULTING FROM LOST DATA OR INABILITY
TO USE DATA) IRRESPECTIVE OF WHETHER SUCH PARTY HAS BEEN INFORMED OF, KNEW OF,
OR SHOULD HAVE KNOWN OF THE LIKELIHOOD OF SUCH DAMAGES, EXCEPT AS EXPRESSLY
PROVIDED IN ARTICLES 5 AND 6 AND 9, AND IN THE SENTENCE SET FORTH BELOW AT THE
END OF THIS ARTICLE 7.  THIS LIMITATION APPLIES TO ALL CAUSES OF ACTION IN THE
AGGREGATE, INCLUDING WITHOUT LIMITATION BREACH OF CONTRACT, BREACH OF WARRANTY,
NEGLIGENCE, STRICT LIABILITY, MISREPRESENTATION, AND OTHER TORTS, NOR SHALL
EITHER PARTY BE LIABLE FOR ANY CLAIM OR DEMAND AGAINST THE OTHER PARTY BY ANY
OTHER PERSON, ORGANIZATION OR ENTITY (EXCEPT AS EXPRESSLY SET FORTH IN ARTICLE
6).  ETAK SHALL NOT BE LIABLE TO LUCENT BECAUSE OF ANY EXPIRATION, TERMINATION
OR FAILURE TO RENEW OR EXTEND THIS AGREEMENT, OR FOR FAILURE TO TIMELY DELIVER
PRODUCT.  IF ETAK'S LIMITED WARRANTY OR THE LIMITATION OF LIABILITY SET FORTH IN
THIS AGREEMENT SHALL FOR ANY REASON WHATSOEVER BE HELD UNENFORCEABLE OR
INAPPLICABLE, EACH PARTY AGREES THAT THE OTHER PARTY'S LIABILITY SHALL NOT
EXCEED FIFTY PERCENT (50%) OF THE ROYALTIES PAID BY LUCENT TO ETAK WITH RESPECT
TO THE LICENSED PRODUCTS UNITS THAT ARE THE SUBJECT OF THE CLAIM.  EXCEPTION:
THIS ARTICLE 7 SHALL NOT APPLY TO ANY CLAIM BY ETAK AGAINST LUCENT WITH RESPECT
TO:  (1) VIOLATION OF ANY OF ETAK'S INTELLECTUAL PROPERTY RIGHTS; (2) VIOLATION
BY LUCENT OF ARTICLES 2 OR 4 HEREOF.  FURTHER, THIS ARTICLE 7 SHALL NOT BE
CONSTRUED TO PRECLUDE ETAK FROM COLLECTING FEES AND ROYALTIES OWED BY LUCENT
UNDER THE PROVISIONS OF THIS AGREEMENT.

ARTICLE 8: RECORDS, REPORTS AND AUDITS

     8.1  Required Records.  Lucent shall prepare and maintain at its expense
          ----------------
complete and accurate books and records documenting the provision of any
Geographic Services to End Users and Lucent Customers, and any revenues of any
type received or derived therefrom.  The books and records prepared by Lucent
shall be retained for a minimum of three (3) years from the date on which Lucent
is obligated to pay such fee to Etak.

     8.2  Reports to Etak. Lucent shall, within thirty (30) days after the end
          ---------------
of each calendar month, provide Etak with a written report of Lucent activities
under this Agreement. Such report shall include the number of Internet accesses
of the Geographic Services occurring that month, and shall state the gross
revenue received or derived by Lucent from the Products or related services.
Etak shall hold such information confidential, except as needed by Etak to
enforce its rights or Lucent's obligations under this Agreement.

     8.3  Audit.  During the initial term hereof, any renewal periods, and for a
          -----
period of one (1) year after expiration or termination of this Agreement, Etak
shall have the right, not more

  Confidential Materials omitted and filed separately with the Securities and

often than once per year, at its expense and upon reasonable notice, to examine
or have examined by its authorized representative, Lucent's books and records to
determine or verify Lucent's performance hereunder with respect to license and
confidentiality provisions (Articles 2 and 4), the amounts of license, support
and other fees due to Etak by Lucent hereunder, and the extent that such amounts
have been paid, and the accuracy of any such reports furnished by Lucent to
Etak. If the audit demonstrates that Lucent has paid to Etak 95% or less of the
fees or royalties actually owed to Etak, then Lucent shall promptly pay the cost
of such audit, in addition to the amounts actually owed. Etak shall hold
confidential the information obtained from Lucent through such audit, except as
needed by Etak to enforce its rights or Lucent's obligations under this
Agreement. Lucent shall have the option of requiring Etak to use an outside,
independent auditor, for such examination, upon written request to Etak,
provided that Lucent first deposits with such outside auditor the estimated cost
thereof.

ARTICLE 9: TERM AND RENEWAL

     Unless terminated earlier pursuant to any provision of Article 10, this
Agreement shall commence on the date countersigned by an authorized officer of
Etak after having been signed by Lucent, and shall continue in force for three
(3) years from said date. However, Lucent shall have the right to terminate this
Agreement at the end of the first year or second year that this Agreement is in
effect by giving written notice thereof to Etak at least ninety (90) days before
the end of the first year or second year of this Agreement, respectively,
provided that Lucent first pays to Etak a $25,000 termination fee in addition to
all fees and royalties owed by Lucent hereunder through the date of termination.
Thereafter, this Agreement shall be automatically renewed for one-year periods,
unless during any such one-year period either party notifies the other party at
least ten months before the expiration date of this Agreement, as it may have
been extended, of that party's intention not to extend the Agreement, in which
event this Agreement shall expire automatically without judicial action. Etak
shall notify Lucent at least 120 days before the expiration date of this
Agreement, as it may have been extended, of any proposed changes in the
royalties and fees to be paid by Lucent in the renewal period. In no event shall

     Lucent does not have or acquire by execution of this Agreement, by
performance hereunder, or otherwise, any vested right with respect to the
distribution of Products or the renewal of this Agreement.  If Etak continues a
business relationship with Lucent after termination or nonrenewal of this
Agreement, that relationship shall not be construed as a renewal of this
Agreement or a waiver of termination, but such relationship shall be "at will,"
terminable at any time with or without cause or notice by either party, and all
such transactions shall be governed by terms otherwise identical to the relevant
provisions of this Agreement, unless the parties have executed a new written
agreement superseding this Agreement.

action, and (i) with two (2) days' notice if Lucent violates any of the
provisions of Articles 2 or 4; and (ii) with thirty days, notice and opportunity
to cure: if Lucent commits a material breach of any other provision of this
Agreement or otherwise fails materially to fulfill any of its obligations
hereunder, or if Lucent neglects or fails to conduct its business in a manner

of Etak. In addition, Lucent shall have the right to terminate this Agreement
with thirty days' notice and opportunity to cure if Etak commits a material
breach of any provision of this Agreement.

          (b)  Either party hereto may terminate this Agreement immediately upon
written notice to the other party without opportunity for cure if such other
party becomes insolvent or, whether voluntary or involuntary, if any process or
proceeding of any court is instituted against such party by attachment or levy
or execution, in insolvency or bankruptcy, or in receivership, or if any general
assignment is made or attempted to be made for the benefit of creditors by such
party. If either party ceases to conduct its business in the normal course of
business, the other party may by thirty (30) days written notice terminate this
Agreement.

     10.2 Survival.  Termination of this Agreement for any reason or its natural
          --------
expiration shall not relieve Lucent of its obligations to make full payment to

Sections 2.5, 2.7, 2.8, 2.9, Article 4, Article 5, Article 6, Article 7, Article
8, Section 10.3, and Article 11 hereof shall survive any such termination or
expiration.

     10.3 Return of Information. Promptly upon expiration or termination of this

thereof in any form. Concurrently therewith, a duly authorized employee of
Lucent shall certify in writing to Etak that all such materials have been
returned to Etak.

and attorneys' fees.

    11.10 Assignment.  This Agreement shall inure to the benefit of and shall be
          ----------
binding upon the parties hereto and their respective successors, legal
representatives and permitted assigns, except that Lucent shall not assign or
transfer this Agreement or any part hereof without Etak's prior written consent,

    11.11 Force Majeure.  Neither party shall be liable for non-performance or

    11.12 Compliance with Laws.  Lucent acknowledges and understands that the
          --------------------
Products may be subject to restrictions on exportation and re-exportation
pursuant to the United States Export Administration Regulations, 15 CFR Parts
368-399.  Prior to export of any Product, Lucent will be familiar with the
requirements of the Export Administration Regulations and will comply strictly
with those requirements in all transactions involving any Products supplied by
Etak hereunder.  Lucent shall comply with all applicable laws and regulations,
and maintain all required licenses and permits.

government contracts or subcontracts, then Lucent shall ensure that the
government entity receives nothing more than limited license rights to use the
Products pursuant to a sublicense agreement equivalent to that allowed under
section 2.4 and Exhibit B of this Agreement.  Lucent shall inform any government
entity or prime contractor with which it is contracting exactly how it intends
to use the Products in connection with its government contracts, that such
Products are proprietary to Etak and that Licensee has no right to grant to the
government entity or prime contractor any rights in the Products.  The software
is a "commercial item," as that term is defined at 48 C.F.R. 2.101 (Oct. 1995)
consisting of "commercial computer software" and "commercial computer
documentation," as such terms are used in 48 C.F.R. 12.212 (Sept. 1995).
Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4
(June 1995), all U.S. Governmental End Users acquire the software with only
those license rights set forth herein.  For purpose of any public disclosure
provision under any federal, state or local law, it is agreed that these
Products are trade secret and proprietary commercial products and not subject to
disclosure.  The Products are copyright (c) 1984-1996 by Etak, Inc. UNPUBLISHED.

    11.14 No Joint Relationship. Lucent and Etak are independent contractors and
          ---------------------
neither has nor shall have any power, nor will either represent that either has

     (a) Lucent shall pay to Etak in each year that this Agreement is in effect,
a minimum annual guaranteed royalty of [**], payable in installments in the
following manner: [**] shall be paid within thirty (30) days of the commencement
of each annual period, then [**] shall be paid three months after such

Level 1 Etak Map Premium Databases with available one ways     [**]
In year one of this Agreement:                                 [**]
Level 2 Above including Imputed Turn Restrictions and                       [**]

Level 3 Above including full Turn By Turn attributes                        [**]
After year one of this Agreement:
</TABLE>

     The percentage Royalty Rate shall be based on a weighted formula,
calculated as follows:

     Etak will report at the beginning of each calendar quarter the percentage
of the Untied States population that is covered by Etak Level 2 databases and
that has been shipped to Lucent over the term of this Agreement (EL2), and the
percentage of the United States population that is covered by Etak Level 3
databases and that has been shipped to Lucent over the term of this Agreement
(EL3).

     Divide [**]

     Divide [**]

     Multiply [**]

     Multiply [**]

     Divide [**] = the percentage Royalty Base.

Example:  If Etak Level 2 databases cover [**] of the population, while Etak
Level 3 databases cover [**] of the population, the formula would operate as
follows:

     [**] divided by [**]

     [**] divided by [**]

     Multiply [**] by [**]

     Multiply [**] by [**]

     Add [**] and [**]

Through payment of the [**] minimum annual guaranteed royalty set forth above in
B(1)(a), Lucent will have in effect prepaid royalties for that year up to [**]
for the Maps On Us WWW Site. Thus, Lucent shall not be required to actually pay
the royalty amounts set forth above in this section B(1)(b) until the accrued
royalties owed Etak for that year exceed [**], at which point Lucent shall
commence paying to Etak the above royalties.

After Lucent has paid to Etak royalties equal to [**] (including the minimal
annual guaranteed royalty paid by Lucent) in any given annual period that this
Agreement is in effect, the Royalty Rate for the remainder of that same annual
period as set forth above in this

subsection B(1)(b) of this Exhibit A shall decrease to [**] of the percentages
set forth above for Level 1, Level 2, and Level 3. However, at the start of the
next annual period the Royalty Rate shall increase to the figures set for Level
1, Level 2, and Level 3.

Lucent)
Updates to Business Listings              [**] per update

     Re:  Amendment ("the Amendment") to Internet Provider Agreement NO. 96-007
between Lucent Technologies ("Provider") and Etak, Inc. ("Etak") dated November
25, 1996 (the "Agreement").

Provider hereby authorizes Etak to market, distribute and sublicense directly
and through Etak's channels of distribution the Maps On Us Service and Maps On
Us Products and other services that the parties agree to.  For those services
that are actually fulfilled by Provider (rather than by Etak or another party),
Etak shall pay to Provider the greater of:  (a) [**] the royalties that Etak
collects for said services, or (b) [**] of the then current Provider list price
for said services.

Notwithstanding the above, for current customers and prospective customers to
whom Etak has issued a quote as of the date of this Amendment, for which Etak
fulfills services using the Provider services, Etak shall pay Provider [**]
the royalties that Etak collects for said services.

The royalties payable by Provider to Etak as described in the Exhibit A of the
Agreement, shall be [**] for the subcontracted services (Maps On Us Service,
Maps On Us Products and other services that the parties agree to) that are
fulfilled by Provider under this Amendment.

This is a non-exclusive sub-contracting relationship.  Either party may
terminate this sub contracting relationship with 120 days written notice,
without affecting the Agreement.

For each such service set forth above, Provider shall deliver to Etak an
accurate monthly report showing the number of hits that the service for each
particular Etak End User has generated, and based on that report Etak shall make
payment to Provider of applicable royalties within thirty (30) days of Etak's
receipt of that report.

This Amendment shall be conterminous with Agreement.

               AMENDMENT #3 TO ETAK INTERNET PROVIDER AGREEMENT

                                  NO IP-96-007

This is the third Amendment ("Amendment #3") to the Agreement (the "Agreement")
between Lucent Technologies Inc. ("Provider") and Etak, Inc. ("Etak"),
(collectively, the "parties") entered into as of November 25, 1996.

WHEREAS the parties have entered into the Agreement for the licensing of Etak
software and data, and

WHEREAS the parties now wish to amend said Agreement,

Now, therefore, in consideration of the mutual undertakings and agreements
hereinafter set forth the parties agree to amend the Agreement as follows:

     1.   Beginning with the second annual period commencing on December 15,
          1997, through payment of the [**] minimum annual guaranteed royalty
          set forth in Exhibit A, Section B, sub-section 1(a), Provider will
          have, in effect, prepaid royalties for that year up to [**] for the
          Maps On Us WWW site and the Maps on Us Internet Service. Thus, except
          for the revised minimum annual guaranteed royalty of [**] per Lucent
          Customer with Business Listings as set forth in paragraph 2 below,
          Provider shall not be required to actually pay the royalty amounts set
          forth in Section B(1)(b) or Section B(2)(b) until the accrued
          royalties owed Etak for that year exceed [**], at which point Provider
          shall commence paying to Etak the applicable royalties.

     2.   Beginning on June 1, 1997, the minimum annual guaranteed royalties set
          forth in Exhibit A, Section B, sub-section 2(a) shall be [**] for
          Lucent Customers without Business Listings; Lucent shall pay to Etak
          in each year that this Agreement is in effect, a minimum annual
          guaranteed royalty of [**] per Lucent Customer with Business Listings,
          payable within thirty (30) days of the commencement period. This
          minimum annual guaranteed royalty shall be payable regardless of the
          actual Gross Revenues of Lucent and shall not be applied to the
          minimum annual guaranteed royalty set forth in Exhibit A, Section B,
          sub-section 1(a) of the Agreement.

          Through payment of the minimum annual guaranteed royalty of [**] per
          Lucent Customer with Business Listings, Lucent will have in effect
          prepaid royalties for that year up to [**] per Customer with Business
          Listings for the Maps On Us Internet Service. Thus, Lucent shall not
          be required to actually pay the royalty amounts set forth above in
          this section B(2)(b) until the accrued royalties owed Etak with
          respect to that Customer for that year exceed [**], at which point
          Lucent shall commence paying to Etak the above royalties for that
          Customer.

     3.   Lucent shall report all royalties due Etak per Section 8 and Exhibit
          A, Section B as contracted.  Lucent shall pay all royalties due Etak
          per Section 8 and Exhibit A,

                                       27
<PAGE>

          Section B within thirty (30) days of collection of payment by Lucent
          or within sixty (60) days of report to Etak, whichever comes first.

Except as otherwise amended herein, all terms and conditions of the Agreement
shall remain in full force and effect.  In the event of conflict in terms, this
Amendment shall take precedence over the Agreement.

     THIS AMENDMENT SHALL BECOME EFFECTIVE UPON EXECUTION BY AN OFFICER OF ETAK.

Pursuant to Section 11.4 of the Agreement, Etak hereby provides Customer with
written notice that the Business Listings and all updates to the Business
Listings as set forth on Exhibit A, Section A of the Agreement shall be
discontinued on June 15, 1998. In consideration of the discontinuance of the
Business Listings as set forth in Exhibit A, Section A of the Agreement, Etak
agrees to reduce the minimum annual guaranteed royalty set forth in Exhibit A,
Section B of the Agreement by [**] for each month remaining the second year
(12/15/97-12/15/98) of the Agreement in which Customer is no longer using the
Business Listings as provided prior to June 15, 1998 and thereafter by [**] for
each such month remaining in the third year (12/15/98-12/15/99) of the Agreement
following: 1) written notification by Customer to Etak that Customer is no
longer using the Business Listings; 2) return to Etak of all Business Listings
and all Derivative Products that include Business Listings and 3) certification
by a duly authorized employee of Customer that all such materials have been
returned to Etak.

The parties agree to amend Article 11.4 Product Changes of the Agreement by
adding the following sentence at the end of the existing paragraph:  "Except
with respect to the Business Listings, the parties agree that Etak's right to
modify or discontinue any Licensed Product is applicable only to modifications
or discontinuances of the Licensed Products to Etak's customers as a whole due
to changes in the provision by Etak of such Licensed Products."

Except as otherwise amended herein, all terms and conditions of the Agreement
shall remain in full force and effect.  In the event of conflict in terms, this
Amendment shall take precedence over the Agreement.

                  CONVERTIBLE SECURED NOTE PURCHASE AGREEMENT
                  -------------------------------------------

     This Agreement dated as of August 29, 1997 is entered into by and among
Switchboard Incorporated, a Delaware corporation (the "Company"), and Banyan
Systems Incorporated, a Massachusetts corporation (the "Purchaser").

     In consideration of the mutual promises and covenants contained in this
Agreement, the parties hereto agree as follows:

     1.   Authorization and Sale of Note.
          ------------------------------

          1.1  Authorization.  The Company has duly authorized the sale and
               -------------
issuance, pursuant to the terms of this Agreement, of a Convertible Secured Note
in the maximum aggregate principal amount of $3,000,000.00, substantially in the
form attached hereto as Exhibit A (the "Note").  The Note shall be convertible,
                        ---------
pursuant to the terms thereof, into shares of the Company's Series C Convertible
Preferred Stock, $.01 par value per share (the "Series C Preferred"), having the
rights, restrictions, privileges and preferences set forth in the Company's
Certificate of Incorporation, as amended (the "Certificate of Incorporation"),
and the Certificate of Amendment attached hereto as Exhibit B (the "Certificate
                                                    ---------
of Amendment").  The Company has authorized and reserved, and will at all times

shares of its Series C Preferred to satisfy the conversion rights of the holder
of the Note and of its common stock to satisfy the conversion rights of holders
of shares of Series C Preferred set forth in Sections 4 and 5 of the Certificate
of Incorporation.  As soon as practicable following the Closing (as defined
below), the Company will file the Certificate of Amendment with the Secretary of
State of the State of Delaware.  The shares of Series C Preferred into which the
Note is convertible are referred to as the "Shares."

          1.2  Initial Sale of Note.  Subject to the terms and conditions of
               --------------------
this Agreement, at the Initial Closing (as defined below) the Company will sell
and issue to the Purchaser, and the Purchaser will purchase, the Note.  The
initial principal amount of the Note shall be evidenced by a notation on
Schedule I of the Note.  The parties agree and acknowledge that any increases or
decreases in the principal amount of the Note outstanding at any time made in
accordance with Section 1.3 shall be evidenced by a further notation on Schedule
I of the Note (such notation to be made by the Purchaser, who will provide a
copy of the revised Schedule I to the Company).  Any notations made to Schedule
I by the Purchaser shall be binding and final absent manifest error and unless
disputed by the Company within seven (7) business days of receipt by the Company
of such notice from the Purchaser.  The parties further agree and acknowledge
that the form of the Note (specifically the stated maximum aggregate principal
amount of $3,000,000 and the use of Schedule I) is merely intended to facilitate
subsequent increases or decreases, if any, in principal amount in accordance
with Section 1.3 and that the Purchaser shall not, under any circumstances, be
obligated to purchase any additional principal amount beyond the initial
principal amount annotated on Schedule I of the Note.

          1.3  Subsequent Increases and Decreases in Principal Amount.
               ------------------------------------------------------
<PAGE>

               (a)  Investment at the Request of the Company. The Company and
                    ----------------------------------------
the Purchaser further agree that if within 32 months of the date of this
Agreement, in the discretion of the Board of Directors of the Company, the
Company shall desire additional financing, the Company shall deliver to the
Purchaser a written notice requesting that the principal amount of the Note be
increased by the amount stated in the notice in exchange for a payment from the
Purchaser to the Company of such amount. The Purchaser shall have the right (but
not the obligation), for a period of 15 days following delivery of such notice,
to so increase the principal amount of the Note. As a condition precedent to,
and simultaneously with, the increase in the principal amount of the Note, (x)
at the request of the Purchaser, the Company shall deliver to the Purchaser (A)
the most recent available Balance Sheet (as defined in Section 3.9 below), (B)
Exhibit C hereto, updated through the date of the closing of such increase, and
- ---------
(C) a certificate, dated as of the date of the closing of such increase,
certifying that the representations and warranties of the Company contained in
Section 3 of this Agreement are true and correct in all material respects as of
such date, (y) at the request of the Company, the Purchaser shall deliver to the
Company a certificate, dated as of the date of the increase in the principal
amount of the Note, certifying that the representations and warranties contained
in Section 4 of this Agreement with respect to the Purchaser are true and
correct as of such date and (z) Schedule I to the Note shall be updated to
reflect such increase.

               (b)  Investment at the Request of the Purchaser. The Company
                    ------------------------------------------
hereby grants to the Purchaser an option to increase in the principal amount of
the Note up to the maximum aggregate principal amount as set forth in Section
1.1 (the "Option") by delivery of a written notice to the Company (the "Exercise
Notice"). The Purchaser shall have the right to exercise the Option (which shall
be deemed to occur upon delivery of the Exercise Notice for purposes of this
sentence) at any time and from time to time prior to the expiration of the 32-
month period beginning on the date of this Agreement.

               (c)  Redemption at the Request of the Company. The Note may, at
                    ----------------------------------------
the option of the Company, be called for redemption, in whole or in part at any
time, at 100% of the principal amount so redeemed, plus accrued and unpaid
interest on such redeemed principal amount to the date fixed for redemption. The
Company shall give at least thirty (30) days prior written notice of redemption
to the Purchaser at its address below, and the notice of redemption shall
specify the date and place designated for redemption. On or after the redemption
date fixed in the notice of redemption, no further interest shall accrue on the
principal amount so redeemed, and the Note (to the extent so redeemed) shall
cease to be convertible as set forth in Section 2 of the Note, provided that the
Note shall remain convertible as set forth in Section 2 of the Note from the
date of notice of redemption until the redemption date fixed in such notice.
Payment of the redemption price shall be made to the Purchaser of this Note upon
presentation and surrender of this Note accompanied by a duly executed
instrument of transfer in blank, at the principal executive office of the
Company. In the event of a partial redemption, this Note shall be presented to
the Company for endorsement of the amount of payment and date paid as a
condition precedent to such payment.

     2.   The Closing.  The initial closing (the "Initial Closing") of the
          -----------

<PAGE>

terms, subject to (i) applicable bankruptcy, insolvency, reorganization,

standards imposed on creditors and parties to contracts, including, without

execution of and performance of the transactions contemplated by this Agreement
and the Ancillary Agreements and compliance with their provisions by the Company

of Incorporation or By-Laws (each as amended to date) or any indenture, lease,
agreement, obligation or other instrument to which the Company is a party or by

or financial condition.  Based on the representations made by the Purchaser in
Section 4 of this Agreement, the offer and sale of the Note and the Shares to
the Purchaser will be in compliance with applicable Federal and state securities
laws.

          3.8  Litigation.  There is no action, suit or proceeding, or
               ----------
governmental inquiry or investigation, pending, or, to the Company's knowledge,
any basis therefor or threat thereof, against the Company or affecting any of
its properties or assets or, to the Company's knowledge, against any officer or
director of the Company, which questions the validity or enforceability of this
Agreement or the agreements and transactions contemplated hereby or the right of
the Company to enter into this Agreement or the Ancillary Agreements, or which
would have a material adverse effect on the Company's operations or financial
condition, and, to the knowledge of the Company, no event has occurred and no
condition exists on the basis of which any such litigation, proceeding or
investigation might properly be instituted or commenced.

          3.9  Financial Statements.  The Company has furnished to the Purchaser
               --------------------
a complete and correct copy of the unaudited balance sheet of the Company (the
"Balance Sheet") as at June 30, 1997 (the "Balance Sheet Date") and the related
pro forma statements of operations and cash flow for the six (6) months then
ended, compiled by the Company (collectively, the "Financial Statements").  The
Financial Statements are complete and correct, are in accordance with the books
and records of the Company and present fairly the financial condition and
results of operations of the Company, as at the dates and for the periods
indicated, and have been prepared in accordance with generally accepted
accounting principles consistently applied, except that the Financial Statements
have been prepared for the internal use of management and may not be in
accordance with generally accepted accounting principles

                                      -5-
<PAGE>

because of the absence of footnotes normally contained therein and are subject
to normal year-end audit adjustments which in the aggregate will not be
material.

          3.10  Absence of Liabilities.  Except as disclosed in Exhibit C, the
                ----------------------                          ---------
Company did not have, at the Balance Sheet Date, any liabilities of any type
which in the aggregate exceeded $25,000, whether absolute or contingent, which
were not fully reflected on the Balance Sheet, and, since the Balance Sheet
Date, the Company has not incurred or otherwise become subject to any such
liabilities or obligations except in the ordinary course of business.

          3.11  Taxes.  The amount shown on the Balance Sheet as provision for
                -----
taxes is sufficient in all material respects for payment of all accrued and
unpaid Federal, state, county, local and foreign taxes (including penalties and
interest) for the period then ended and all prior periods.  The Company has
filed or has obtained presently effective extensions with respect to all
Federal, state, county, local and foreign tax returns which are required to be
filed by it, such returns are true and correct and all taxes required to be paid
by the Company have been timely paid except those taxes which will not have a
material adverse effect on the business or financial condition of the Company.
No income tax returns of the Company have been audited by any taxing authority,
and no controversy with respect to taxes of any type is pending or, to the best
of the Company's knowledge, threatened.  Neither the Company nor, to its
knowledge, any of its stockholders has ever filed (a) an election pursuant to
Section 1362 of the Internal Revenue Code of 1986, as amended (the "Code"), that
the Company be taxed as an S Corporation or (b) consent pursuant to Section
341(f) of the Code relating to collapsible corporations.  The Company has never
received notice of any audit or of any proposed deficiencies from any taxing
authority.  There are in effect no waivers of applicable statutes of limitations
with respect to any taxes owed by the Company for any year.  No taxing authority
is now asserting or, to the knowledge of the Company, threatening to assert
against the Company any deficiency or claim for additional taxes or interest
thereon or penalties in connection therewith.  The Company's net operating
losses for federal income tax purposes, as set forth in the Financial
Statements, are not subject to any limitations imposed by Section 382 of the
Code, and consummation of the transactions contemplated by this Agreement or by
any other agreement, understanding or commitment, contingent or otherwise, to
which the Company is a party or by which it is otherwise bound will not have the
effect of limiting the Company's ability to use such net operating losses in
full to offset such taxable income.

          3.12  Property and Assets.  The Company has good title to all of its
                -------------------
properties and assets, including all properties and assets reflected in the
Balance Sheet, except those disposed of since the date thereof in the ordinary
course of business or that will not have a material adverse effect on the
Company, and none of such properties or assets is subject to any mortgage,
pledge, lien, security interest, lease, charge or encumbrance that will have a
material adverse effect on the Company, other than those the material terms of
which are described in the Balance Sheet or in Exhibit C.
                                               ---------

          3.13  Intellectual Property.  Except as set forth on Exhibit C:
                ---------------------                          ---------

                (a)  The Company has exclusive ownership in all right, title and
interest to ("Owned Rights"), with the right to use, sell, license, dispose of,
and bring actions for infringement of, or has a valid license to use all
Intellectual Property Rights (as hereinafter

                                      -6-
<PAGE>

defined) used in the conduct of its business as presently conducted and as
proposed to be conducted (the "Company Rights"), which Owned Rights are
exclusive to the Company and which Company Rights are sufficient in all material
respects for the conduct of its business as presently conducted.

                (b)  The business of the Company as presently conducted and the
manufacture, marketing, licensing, use and servicing of any products of the
Company, do not violate any agreements which the Company has with any third
party, infringe any copyright or trade secrets of any third parties, or to the
best knowledge of the Company, infringe any patent, trademark, or any other
Intellectual Property Rights (other than copyrights and trade secrets) of any
third parties.

                (c)  No claim is pending or, to the best knowledge of the
Company, threatened against the Company nor has the Company received any notice
or other claim from any person asserting that any of the Company's present or
contemplated activities infringe or may infringe any Intellectual Property
Rights of such person, and the Company is not aware of any infringement by any
other person of any rights of the Company under any Intellectual Property
Rights.

                (d)  The Company is not aware that any employee is obligated
under any contract (including any license, covenant or commitment of any
nature), or subject to any judgment, decree or order of any court or
administrative agency, that would materially conflict or interfere with (i) the
performance of such employee's duties as an officer, employee or director of the
Company, (ii) the use of such employee's best efforts to promote the interests
of the Company or (iii) the Company's business as conducted or proposed to be
conducted.

shall mean all intellectual property rights, including, without limitation, all
of the registered rights set forth on Exhibit C and all patents, patent
                                      ---------

without limitation, manuals, memoranda and records. Exhibit C contains a list
                                                    ---------
and brief description of all Intellectual Property Rights owned by or registered
in the name of the Company or of which the Company is the licensor or a licensee
of a material right or in which the Company has any material right and, in each
case, a brief description of the nature of the right.

          3.14  Insurance.  Except as set forth on Exhibit C, the Company
                ---------                          ---------
maintains valid policies of workers' compensation insurance and of insurance
with respect to its properties and business of the kinds and in the amounts not
less than is customarily obtained by corporations of established reputation
engaged in the same or similar business and similarly situated.  There is no
default under any such policy, nor, to the knowledge of the Company, has any
event occurred which with notice, lapse of time or both would constitute a
material default thereunder.

previously issued and sold by the Company to the Purchaser pursuant to the
Agreement shall be cancelled, and the Company shall issue and sell to the
Purchaser (i) a new note in the aggregate principal amount of $10,000,000, which
is convertible into Series C Convertible Preferred Stock of the Company at an
initial conversion price of $4.00 per share (the "Series C Replacement Note"),
and (ii) a new note in the aggregate principal amount of $5,000,000, which is
convertible into Series D Convertible Preferred Stock of the Company at an
initial conversion price of $7.50 per share (the "Series D Note").  The terms of
the Series C Replacement Note shall in all other respects be identical to the
terms of the Note (including an identical effective date).  The Series D Note

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

to and including the aggregate principal amount of $10,000,000 shall be made
under the Series C Replacement Note.  Any loans beyond such $10,000,000 amount

"Note" shall be deemed to be references to the Series C Replacement Note and the
Series D Note.  All references in the Agreement to "$7,000,000" shall be to
"$10,000,000" with respect to the Series C Replacement Note and to "$5,000,000"

remain in full force and effect. Any rights either party hereto may have as a
result of a breach of, or misrepresentation contained in, the Agreement prior to
this Amendment shall remain in full force

                            SWITCHBOARD INCORPORATED

           Amended and Restated Convertible Note Due January 1, 2001

$3,904,328.42                                            Westboro, Massachusetts
                                                                January 26, 2000

                             _____________________

     This Amended and Restated Convertible Note due January 1, 2001 (this
"Note") amends and restates in its entirety that certain Convertible Secured
Note due June 29, 2000 (the "Original Note") dated May 3, 1999 by Switchboard
Incorporated, a Delaware corporation (the "Company"), to Banyan Systems
Incorporated, a Massachusetts corporation ("Banyan"), pursuant to Section 4(b)
of the Original Note with the consent of the Company and Banyan.  As of June 30,
1999 and July 1, 1999, Banyan converted an aggregate of $1,095,671.58 of
outstanding principal and an aggregate of $3,115.92 of outstanding interest
under the Original Note into an aggregate of 146,505 shares of the Company's
Series D Convertible Preferred Stock, $.01 par value per share (the "Series D
Preferred"), pursuant to Section 2(a)(i) of the Original  Note.  The principal
amount available under this Note reflects the remaining balance of the principal
amount available under the Original Note subsequent to such conversion.
Concurrently with the execution of this Note, the Original Note is cancelled and
shall be of no further force and effect.

     The Company, for value received, hereby promises to pay to Banyan, on
January 1, 2001, the principal sum of Three Million, Nine Hundred Four Thousand,
Three Hundred Twenty-Eight Dollars and Forty-Two Cents ($3,904,328.42) or such
lesser amount as may at the maturity hereof, whether by acceleration or
otherwise, be the aggregate unpaid principal amount of this Note as shown on
Schedule I hereto as such schedule will be updated from time to time, with
interest (computed annually on the basis of a 365-day year) from the date hereof
on the unpaid balance of such principal amount from time to time outstanding at
the fluctuating interest rate per annum described below, such interest to be due
and payable on January 1, 2001.  The interest rate per annum with respect to
each loan evidenced hereby shall equal the applicable federal rate under Section
1274 of the Internal Revenue Code of 1986, as amended, for short-term loans with
annual compounding of interest for the month in which such loan is made.

     This Note is limited in aggregate principal amount to $3,904,328.42 and is
issued by the Company pursuant to the Convertible Secured Note Purchase
Agreement dated as of August 29,
<PAGE>

1997 between the Company and Banyan, as amended (the "Purchase Agreement"), to
which reference is made for a statement of certain additional rights and
benefits to which the holder of this Note is entitled. Banyan is authorized to
record all loans evidenced hereby in its records (including, but not limited to,
the grid attached hereto as Schedule I), and such entries shall be conclusive
evidence of amounts outstanding hereunder absent manifest error and unless
disputed by the Company within seven (7) business days of receipt by the Company
of such revision to Schedule I.

     In order to request an advance hereunder, the Company shall deliver or fax
to Banyan a request in the form of Schedule II attached hereto, executed by the
Company, setting forth the amount of the requested advance and the interest rate
with respect to such advance. Within fifteen (15) business days of Banyan's
receipt of such a request, Banyan shall advance the requested amount by wire
transfer of immediately available funds to an account designated by the Company
or by other means mutually agreed upon by Banyan and the Company.

1.  No Security.  Payment of this Note is not secured by any pledge, lien or any
    -----------
other security interest.

2.  Conversion.
    ----------

    (a) General.  This Note shall be subject to optional conversion and
        -------
mandatory conversion as set forth below:

        (i)  Optional Conversion.  The holder of this Note has the right, at its
             -------------------
option, at any time that any amount of principal or accrued interest is
outstanding hereunder, to convert any or all of the outstanding amount of
principal and/or interest of this Note into fully paid and non-assessable shares
of Series D Preferred at the rate of one share of Series D Preferred for each
$11.00 of the outstanding principal amount and/or accrued interest hereunder
surrendered for conversion, subject to adjustment as set forth herein (the
"Conversion Price"). In order to exercise this optional conversion privilege,
the holder of this Note shall surrender this Note to the Company during usual
business hours at the Company's principal executive office, accompanied by
written notice in form reasonably satisfactory to the Company that the holder
elects to convert the entire amount of this Note or a portion hereof specified
in such notice. Such notice shall also state the name or names (with address) in
which the certificate or certificates for shares of Series D Preferred which
shall be issuable on such conversion shall be issued.

        (ii) Mandatory Conversion.  The entire outstanding amount of principal
             --------------------
and accrued interest of this Note shall automatically be converted into fully
paid and non-assessable shares of Series D Preferred at the then effective
Conversion Price immediately prior to the consummation of an underwritten public
offering pursuant to an effective registration statement under the Securities
Act of 1933, as amended, covering the offer and sale by the Company of Common
Stock to the public, in which the Company, prior to giving effect to the
proceeds of the offering, is valued at at least $135,000,000 (determined by
multiplying the number of outstanding shares of capital stock of the Company on
a fully diluted basis by the initial public offering price) and resulting in at
least $15,000,000 in net proceeds (determined by subtracting underwriters'
discounts and commissions from gross proceeds) to the Company (a "Conversion
IPO").  The Company shall cause notice of mandatory conversion to be mailed to
the registered

                                      -2-
<PAGE>

holder of this Note, at such holder's address appearing below, at least ten (10)
days prior to the date fixed for mandatory conversion of this Note. On or before
the date fixed for mandatory conversion, the holder shall surrender this Note at
the place designated in such notice, together with a statement of the name or
names (with address) in which the certificate or certificates for shares of
Series D Preferred which shall be issuable on such conversion shall be issued.
Upon the consummation of a Conversion IPO, other than to the extent necessary to
govern any mandatory conversion upon such Conversion IPO, this Note shall be
deemed cancelled in full, shall be of no further force and effect and no further
advances shall be made hereunder.

     (b) Surrender of Note and Delivery of Certificates.  When surrendered for
         ----------------------------------------------
optional or mandatory conversion this Note shall, unless the shares issuable on
conversion are to be issued in the same name as the name in which this Note is
then registered, be duly endorsed by, or accompanied by instruments of transfer
in form satisfactory to the Company duly executed by, the holder or his or its
duly authorized attorney.  As promptly as practicable after the surrender of
this Note for conversion and the receipt of the notice specified above (in the
case of optional conversion), the Company shall deliver or cause to be delivered
at its principal executive office to the holder, or on the holder's written
order, a certificate or certificates for the number of full shares issuable upon
the conversion of this Note, or portion hereof, in accordance with the
provisions hereof.  Such conversion shall be deemed to have been made at the
time this Note shall have been surrendered for conversion and the notice
specified above (in the case of optional conversion) shall have been received by
the Company at its principal executive office (the "Conversion Date"), and the
holder in whose name any certificate or certificates for shares of Series D
Preferred shall be issuable upon such conversion shall be deemed to have become
on the Conversion Date the holder of record of the shares represented thereby.
If less than the entire outstanding principal amount of this Note is being
converted (in the case of optional conversion), a new Note shall promptly be
delivered to the holder for the unconverted principal balance and shall be of
like tenor as to all terms as the Note surrendered.

     (c) Adjustment of Conversion Price.
         ------------------------------

         (i)  In case the Company shall:

              (A) declare a dividend of Series D Preferred on its Series D
Preferred,

              (B) subdivide outstanding Series D Preferred into a larger number
of shares of Series D Preferred by reclassification, stock split or otherwise,
or

              (C) combine outstanding Series D Preferred into a smaller number
of shares of Series D Preferred by reclassification or otherwise,

     the number of shares of Series D Preferred issuable upon conversion of this
Note immediately prior to any such event shall be adjusted proportionately so
that thereafter the holder of this Note shall be entitled to receive upon
conversion of this Note the number of shares of Series D Preferred which such
holder would have owned after the happening of any of the events described above
had this Note been converted immediately prior to the happening of such event,
provided that the Conversion Price shall in no event be reduced to less than the
par value of the shares issuable upon conversion.  An adjustment made pursuant
to this Section 2(c) shall become

                                      -3-
<PAGE>

effective immediately after the record date in the case of a dividend and shall
become effective immediately after the effective date in the case of a
subdivision or combination.

         (ii)   If, prior to maturity of this Note, the Company shall at any
time consolidate or merge with another corporation (other than a merger or
consolidation in which the Company is the surviving corporation), the registered
holder hereof will thereafter be entitled to receive, upon the conversion
hereof, the securities or property to which a holder of the number of shares of
Series D Preferred then deliverable upon the conversion hereof would have been
entitled upon such consolidation or merger, and the Company shall take such
steps in connection with such consolidation or merger as may be necessary to
ensure that the provisions hereof shall thereafter be applicable, as nearly as
reasonably may be, in relation to any securities or property thereafter
deliverable upon the conversion of this Note.

         (iii)  If the Company shall sell equity securities in a capital raising
transaction or engage in any other transaction that is material to the Company,
then the Company and Banyan shall determine in good faith the fair market value
per share of Series D Preferred immediately following such transaction based, if
applicable, upon the actual or implied value of the Company in such transaction.
The Conversion Price shall be adjusted to reflect such fair market value;
provided, however, that such adjusted Conversion Price shall apply only to
- --------  -------
amounts advanced by Banyan hereunder subsequent to such transaction and shall
not apply to amounts advanced by Banyan hereunder prior to such transaction. The
Conversion Price applicable to each advance hereunder shall be set forth on
Schedule I.

     (d) Notice.  In case the Company proposes to take any action referred to in
         ------
Section 2(c) above, or to effect the liquidation, dissolution or winding up of
the Company, then the Company shall cause notice thereof to be mailed to the
registered holder of this Note, at the address appearing below, at least twenty
(20) days prior to the date on which the transfer books of the Company shall
close or a record be taken for such stock dividend or the date when such
reclassification, liquidation, dissolution or winding up shall be effective, as
the case may be.

     (e) Statement of Adjustment.  Whenever the Conversion Price shall be
         -----------------------
adjusted as provided in Section 2(c) above, the Company shall forthwith send, by
mail, first class, postage prepaid, to Banyan, at the address appearing below, a
statement, signed by the Chairman of the Board, the President, any Vice
President, the Treasurer or Secretary of the Company, showing in reasonable
detail the facts requiring such adjustment and the Conversion Price that will be
effective after such adjustment.   Where appropriate, such notice may be given
in advance and may be included as part of a notice required to be mailed under
the provisions of Section 2(d) hereof.

     (f) Fractional Shares.  No fractional shares of Series D Preferred shall be
         -----------------
issuable upon conversion of this Note, but a payment in cash will be made in
respect of any fraction of a share which would otherwise be issuable upon the
surrender of this Note, or portion hereof, for conversion.  Such payment shall
be based on the fair market value of the Series D Preferred at the time of
conversion of this Note, as determined in good faith by the Board of Directors.

     (g) Securities Act of 1933.  Upon conversion of this Note, the registered
         ----------------------
holder may be required to execute and deliver to the Company an instrument, in
form reasonably satisfactory

                                      -4-
<PAGE>

to the Company, representing that the shares issuable upon conversion hereof are
being acquired for investment and not with a view to distribution within the
meaning of the Securities Act of 1933, as amended.

3.   Default.
     -------

     The entire unpaid principal of this Note and the interest then accrued on
this Note shall become and be immediately due and payable upon written demand of
the holder of this Note, without any other notice or demand of any kind or any
presentment or protest, if any one of the following events shall occur and be
continuing at the time of such demand, whether voluntarily or involuntarily, or,
without limitation, occurring or brought about by operation of law or pursuant
to or in compliance with any judgment, decree or order of any court or any
order, rule or regulation of any governmental body:

     (a) If default shall be made in the payment of any installment of principal
of the Note, or of any installment of interest on the Note, and if any such
default shall remain unremedied for ninety (90) days; or

     (b) If the Company (i) makes a composition or an assignment for the benefit
of creditors or trust mortgage, (ii) applies for, consents to, acquiesces in,
files a petition seeking or admits (by answer, default or otherwise) the
material allegations of a petition filed against it seeking the appointment of a
trustee, receiver or liquidator, in bankruptcy or otherwise, of itself or of all
or a substantial portion of its assets, or a reorganization, arrangement with
creditors or other remedy, relief or adjudication available to or against a
bankrupt, insolvent or debtor under any bankruptcy or insolvency law or any law
affecting the rights of creditors generally, or (iii) admits in writing its
inability to pay its debts generally as they become due; or

     (c) If an order for relief shall have been entered by a bankruptcy court or
if a decree, order or judgment shall have been entered adjudging the Company
insolvent, or appointing a receiver, liquidator, custodian or trustee, in
bankruptcy or otherwise, for it or for all or a substantial portion of its
assets, or approving the winding-up or liquidation of its affairs on the grounds
of insolvency or nonpayment of debts, and such order for relief, decree, order
or judgment shall remain undischarged or unstayed for a period of ninety (90)
days; or if any substantial part of the property of the Company is sequestered
or attached and shall not be returned to the possession of the Company or such
subsidiary or released from such attachment within ninety (90) days.

4.   General.
     -------

     (a) Replacement.  Upon receipt by the Company of evidence reasonably
         -----------
satisfactory to it of the loss, theft, destruction or mutilation of this Note
and of indemnity reasonably satisfactory to it, and upon reimbursement to the
Company of all reasonable expenses incidental thereto, and upon surrender and
cancellation of this Note (in case of mutilation) the Company will make and

          2.1    Required Registrations.
                 ----------------------

                                      -2-
<PAGE>

          (a)    At any time after the first anniversary of the closing of the
Initial Public Offering, Banyan may request, in writing, that the Company effect
the registration on Form S-3 (or any successor form) of Registrable Shares owned
by Banyan having an aggregate value of at least $10,000,000 (based on the then
current market price or fair value).  For avoidance of doubt, the parties agree
that the Company shall not be required to file a registration statement on Form
S-1 or Form S-2 (or any successor form which does not allow the incorporation by
reference of subsequently filed Exchange Act reports).

          (b)    Upon receipt of any request for registration pursuant to this
Section 2, the Company shall promptly give written notice of such proposed
registration to all other Stockholders.  Such Stockholders shall have the right,
by giving written notice to the Company within 10 days after the Company
provides its notice, to elect to have included in such registration such of
their Registrable Shares as such Stockholders may request in such notice of
election, subject in the case of an underwritten offering to the approval of the
managing underwriter as provided in Section 2.1(c) below.  Thereupon, the
Company shall, as expeditiously as possible, use its reasonable best efforts to
effect the registration on an appropriate registration form of all Registrable
Shares which the Company has been requested to so register.

          (c)    If Banyan intends to distribute the Registrable Shares covered
by its request by means of an underwriting, it shall so advise the Company as a
part of its request made pursuant to Section 2.1(a), and the Company shall
include such information in its written notice referred to in Section 2.1(b).
The right of any other Stockholder to include its Registrable Shares in such
registration pursuant to Section 2.1(a) shall be conditioned upon such other
Stockholder's participation in such underwriting on the terms set forth herein.
If other holders of securities of the Company who are entitled, by contract with
the Company, to have securities included in such a registration (the "Other
Holders") request such inclusion, the Company may include the securities of such
Other Holders in such registration and underwriting on the terms set forth
herein. The Company shall (together with all Stockholders and Other Holders
proposing to distribute their securities through such underwriting) enter into
an underwriting agreement in customary form (including, without limitation,
customary indemnification and contribution provisions on the part of the
Company) with the managing underwriter. Notwithstanding any other provision of
this Section 2.1(c), if the managing underwriter advises the Company that the
inclusion of all shares requested to be registered would adversely affect the
offering, and if a limitation of the number of shares is required, the number of
shares that may be included in such registration and underwriting shall, except
as otherwise provided in any contract to which the Company is a party, be
allocated among all holders of Registrable Shares and Other Holders requesting
registration in proportion, as nearly as practicable, to the

                                      -3-
<PAGE>

respective number of shares held by them at the time of the request for
registration made pursuant to Section 2.1(a). For the avoidance of doubt, the
parties agree that no Stockholder shall be entitled to include any shares in a
registration requested pursuant to its rights under this Section 2.1 unless each
Other Holder under the following listed agreements (which term includes Banyan
to the extent so provided in one of the following listed agreements) is entitled
to include in such registration all of the shares of Common Stock which it
desires to include and which are registrable shares under one of the following
listed agreements: (1) Amended and Restated Registration Rights Agreement, dated
as of February 20, 1998, as amended, among the Company, America Online, Inc.,
Digital City Inc. and Banyan; (2) Registration Rights Agreement dated as of
December 31, 1997, between the Company and Continuum Software, Inc.; (3) Amended
and Restated Registration Rights Agreement dated as of May 3, 1999 between the
Company and Banyan; and (4) Registration Rights Agreement dated as of June 30,
1999 between the Company and CBS Corporation. If any holder of Registrable
Shares or Other Holder who has requested inclusion in such registration as
provided above disapproves of the terms of the underwriting, such person may
elect to withdraw therefrom by written notice to the Company, and the securities
so withdrawn shall also be withdrawn from registration. If the managing
underwriter has not limited the number of Registrable Shares or other securities
to be underwritten, the Company may include securities for its own account in
such registration if the managing underwriter so agrees and if the number of
Registrable Shares and other securities which would otherwise have been included
in such registration and underwriting will not thereby be limited.

          (d)    The Company shall have the right to select the managing
underwriter(s) for any underwritten offering requested pursuant to Section
2.1(a), subject to the approval of Banyan, which approval will not be
unreasonably withheld.

          (e)    The Company shall not be required to effect more than one
registration pursuant to Section 2.1(a) per year.  In addition, the Company
shall not be required to effect any registration within six months after the
effective date of any other Registration Statement of the Company.  For purposes
of this Section 2.1(e), a Registration Statement shall not be counted until such
time as such Registration Statement has been declared effective by the
Commission (unless Banyan withdraws its request for such registration (other
than as a result of material information concerning the business or financial
condition of the Company which is first made known to Banyan after the date on
which such registration was requested) and elect not to pay the Registration
Expenses therefor pursuant to Section 2.4).  In the event Banyan is, as a result
of the cut-back provisions in Section 2.1(c), prohibited from selling at least
50% of the Registrable Shares with respect to which it requested registration,
then such registration shall not count as a registration under this Section
2.1(e).

                                      -4-
<PAGE>

          (f)    If at the time of any request to register Registrable Shares by
Banyan pursuant to this Section 2.1, the Company is engaged or has plans to
engage in a registered public offering or is engaged in any other activity
which, in the good faith determination of the Company's Board of Directors,
would be adversely affected by the requested registration, then the Company,
upon furnishing a certificate signed by an executive officer or the Chairman of
the Board of the Company stating that the Board has made the foregoing
determination, may at its option direct that such request be delayed for a
period not in excess of 75 days from the date of such request; provided,
                                                               --------
however, that the Company may not utilize this right more than twice in any
- -------
twelve month period.

     2.2  Incidental Registration.
          -----------------------

          (a)    Whenever the Company proposes to file a Registration Statement
(other than a Registration Statement filed pursuant to Section 2.1 and a
Registration Statement covering shares to be sold solely for the account of
Other Holders in which the Company is contractually prohibited from including
Registrable Shares), at any time and from time to time, it will, prior to such
filing, give written notice to all Stockholders of its intention to do so;
provided that no such notice need be given if no Registrable Shares are to be
included therein as a result of a determination of the managing underwriter
pursuant to Section 2.2(b).  Upon the written request of a Stockholder or
Stockholders given within 10 days after the Company provides such notice (which
request shall state the intended method of disposition of such Registrable
Shares), the Company shall use its best efforts to cause all Registrable Shares
which the Company has been requested by such Stockholder or Stockholders to
register to be registered under the Securities Act to the extent necessary to
permit their sale or other disposition in accordance with the intended methods
of distribution specified in the request of such Stockholder or Stockholders;
provided that the Company shall have the right to postpone or withdraw any
registration effected pursuant to this Section 2.2 without obligation to any
Stockholder.

          (b)    If the registration for which the Company gives notice pursuant
to Section 2.2(a) is a registered public offering involving an underwriting, the
Company shall so advise the Stockholders as a part of the written notice given
pursuant to Section 2.2(a). In such event, the right of any Stockholder to
include its Registrable Shares in such registration pursuant to this Section 2.2
shall be conditioned upon such Stockholder's participation in such underwriting
on the terms set forth herein. All Stockholders proposing to distribute their
securities through such underwriting shall (together with the Company and Other
Holders distributing their securities through such underwriting), enter into an
underwriting agreement in

                                      -5-
<PAGE>

customary form with the underwriter or underwriters selected for the
underwriting by the Company. Notwithstanding any other provision of this Section
2.2, if the managing underwriter determines that the inclusion of all shares
requested to be registered would adversely affect the offering, the Company may
limit the number of Registrable Shares to be included in the registration and
underwriting. The Company shall so advise all holders of Registrable Shares
requesting registration, and the number of shares that are entitled to be
included in the registration and underwriting shall be allocated as follows:

                    (i)    first, there shall be included any shares proposed to
be sold by the Company;

                    (ii)   second, there shall be included any shares permitted
to be included in the registration pursuant to Section 3(b) of the Amended and
Restated Registration Rights Agreement, dated as of February 20, 1998, as
amended, among the Company, America Online, Inc., Digital City Inc., and Banyan;

                    (iii)  third, there shall be included in the registration
any shares permitted to be included pursuant to Section 2(b) of the Registration
Rights Agreement dated as of December 31, 1997 between the Company and Continuum
Software, Inc.;

                    (iv)   fourth, there shall be included in the registration
any shares permitted to be included pursuant to Section 3(b) of the Amended and
Restated Registration Rights Agreement dated as of May 3, 1999 between the
Company and Banyan;

                    (v)    fifth, there shall be included in the registration
any shares permitted to be included pursuant to Section 2(b) of the Registration
Rights Agreement dated as of June 30, 1999 between the Company and CBS
Corporation; and

                    (vi)   sixth, except as otherwise required in any contract
to which the Company is a party, there shall be included in the registration any
shares requested to be included by the Stockholders and any Other Holders in
proportion, as nearly as practicable, to the respective number of shares of
Common Stock (on an as-converted basis) which they held at the time the Company
gives the notice specified in Section 2.2(a).

If any Stockholder or Other Holder would thus be entitled to include more
securities than such holder requested to be registered, the excess shall be
allocated among other requesting Stockholders and Other Holders pro rata in the
manner described in clause

                                      -6-
<PAGE>

(vi) of the preceding sentence. If any holder of Registrable Shares or Other
Holder disapproves of the terms of any such underwriting, such person may elect
to withdraw therefrom by written notice to the Company, and any Registrable
Shares or other securities excluded or withdrawn from such underwriting shall be
withdrawn from such registration.

          2.3    Registration Procedures.
                 -----------------------

                 (a)    If and whenever the Company is required by the
provisions of this Agreement to use its reasonable best efforts to effect the
registration of any Registrable Shares under the Securities Act, the Company
shall:

                        (i)     with respect to a registration under Section 2.1
above, (1) file with the Commission a Registration Statement with respect to
such Registrable Shares as soon as practicable (but in any event within 60 days
after receipt of the request under Section 2, unless the filing of such
registration statement will require the preparation of financial statements that
have not been prepared as of the date of the receipt of the request, in which
case the filing will be made within 90 days after receipt of the request) and
(2) use its reasonable best efforts to cause that Registration Statement to
become effective as soon as possible;

                        (ii)    with respect to a registration under Section 2.1
above, as expeditiously as reasonably possible prepare and file with the
Commission any amendments and supplements to the Registration Statement and the
prospectus included in the Registration Statement as may be necessary to comply
with the provisions of the Securities Act (including the anti-fraud provisions
thereof) and to keep the Registration Statement effective for 120 days from the
effective date or such lesser period until all such Registrable Shares are sold;

                        (iii)   as expeditiously as reasonably possible furnish
to each Selling Stockholder such reasonable numbers of copies of the Prospectus,
including any preliminary Prospectus, in conformity with the requirements of the
Securities Act, and such other documents as such Selling Stockholder may
reasonably request in order to facilitate the public sale or other disposition
of the Registrable Shares owned by such Selling Stockholder;

                        (iv)    as expeditiously as reasonably possible use its
reasonable best efforts to register or qualify the Registrable Shares covered by
the Registration Statement under the securities or Blue Sky laws of such states
as the Selling Stockholders shall reasonably request; provided, however, that
                                                      --------  -------
the Company

                                      -7-
<PAGE>

shall not be required in connection with this paragraph (iv) to qualify as a
foreign corporation or execute a general consent to service of process in any
jurisdiction;

                        (v)     as expeditiously as reasonably possible, cause
all such Registrable Shares to be listed on each securities exchange or
automated quotation system on which similar securities issued by the Company are
then listed;

                        (vi)    promptly provide a transfer agent and registrar
for all such Registrable Shares not later than the effective date of such
registration statement;

                        (vii)   notify each Selling Stockholder, reasonably
promptly after it shall receive notice thereof, of the time when such
Registration Statement has become effective or a supplement to any Prospectus
forming a part of such Registration Statement has been filed; and

                        (viii)  notify each seller of such Registrable Shares of
any request by the Commission for the amending or supplementing of such
Registration Statement or Prospectus.

                 (b)    If the Company has delivered a Prospectus to the Selling
Stockholders and after having done so the Prospectus is amended to comply with
the requirements of the Securities Act, the Company shall reasonably promptly
notify the Selling Stockholders and, if requested, the Selling Stockholders
shall immediately cease making offers of Registrable Shares and return all
Prospectuses to the Company. The Company shall reasonably promptly provide the
Selling Stockholders with revised Prospectuses and, following receipt of the
revised Prospectuses, the Selling Stockholders shall be free to resume making
offers of the Registrable Shares.

                 (c)    In the event that, in the judgment of the Company, it is
advisable to suspend use of a Prospectus included in a Registration Statement
due to pending material developments or other events that have not yet been
publicly disclosed and as to which the Company believes public disclosure would
be detrimental to the Company, the Company shall notify all Selling Stockholders
in writing to such effect, and, upon receipt of such notice, each such Selling
Stockholder shall immediately discontinue any sales of Registrable Shares
pursuant to such Registration Statement until such Selling Stockholder has
received copies of a supplemented or amended Prospectus or until such Selling
Stockholder is advised in writing by the Company that the then current
Prospectus may be used and has received copies of any additional or supplemental
filings that are incorporated or deemed incorporated by reference in such
Prospectus. The Company, as expeditiously as reasonably possible, shall advise
the Selling Stockholders that use of the then

                                      -8-
<PAGE>

current Prospectus may be resumed or deliver copies of a supplemented or amended
Prospectus.

          2.4    Allocation of Expenses.  The Company will pay all Registration
                 ----------------------
Expenses for all registrations under this Agreement; provided, however, that if
a registration under Section 2.1 is withdrawn at the request of Banyan (other
than as a result of information concerning the business or financial condition
of the Company which is first made known to Banyan after the date on which such
registration was requested or pursuant to the final sentence of Section 2.1(e))
and if Banyan elects not to have such registration counted as a registration
requested under Section 2.1, Banyan shall pay the Registration Expenses of such
registration.  For purposes of this Section 2.4, the term "Registration
Expenses" shall mean all expenses incurred by the Company in complying with this
Agreement, including, without limitation, all registration and filing fees,
Nasdaq and exchange listing fees, printing expenses, fees and expenses of
counsel for the Company, compensation of the employees of the Company and the
reasonable fees and expenses of one counsel selected by the Selling Stockholders
to represent the Selling Stockholders, state Blue Sky fees and expenses, and the
expense of any special audits incident to or required by any such registration,
but excluding underwriting discounts, selling commissions and the fees and
expenses of Selling Stockholders' own counsel (other than the counsel selected
to represent all Selling Stockholders).

          2.5    Indemnification and Contribution.
                 --------------------------------

                 (a)    In the event of any registration of any of the
Registrable Shares under the Securities Act pursuant to this Agreement, the
Company will indemnify and hold harmless the seller of such Registrable Shares
and each of its officers, directors, employees and partners, each underwriter of
such Registrable Shares, and each other person, if any, who controls such seller
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
such seller, underwriter or controlling person may become subject under the
Securities Act, the Exchange Act, state securities or Blue Sky laws or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any Registration Statement
under which such Registrable Shares were registered under the Securities Act,
any preliminary prospectus or final prospectus contained in the Registration
Statement, or any amendment or supplement to such Registration Statement, or
arise out of or are based upon the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading; and the Company will reimburse such seller, underwriter
and each such controlling person, on

                                      -9-
<PAGE>

at least a quarterly basis for any legal or any other expenses reasonably
incurred by such seller, underwriter or controlling person in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the Company will not be liable in any such case to the
- --------  -------
extent that any such loss, claim, damage or liability arises out of or is based
upon any untrue statement or omission made in such Registration Statement,
preliminary prospectus or prospectus, or any such amendment or supplement, in
reliance upon and in conformity with information furnished to the Company, in
writing, by or on behalf of such seller, underwriter or controlling person
specifically for use in the preparation thereof.

                 (b)    In the event of any registration of any of the
Registrable Shares under the Securities Act pursuant to this Agreement, each
seller of Registrable Shares, severally and not jointly, will indemnify and hold
harmless the Company, each of its directors and officers and each underwriter
(if any) and each person, if any, who controls the Company or any such
underwriter within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages or liabilities, joint or several, to which
the Company, such directors and officers, underwriter or controlling person may
become subject under the Securities Act, Exchange Act, state securities or Blue
Sky laws or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in any
Registration Statement under which such Registrable Shares were registered under
the Securities Act, any preliminary prospectus or final prospectus contained in
the Registration Statement, or any amendment or supplement to the Registration
Statement, or arise out of or are based upon any omission or alleged omission to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, if the statement or omission was made in
reliance upon and in conformity with information relating to such seller
furnished in writing to the Company by or on behalf of such seller specifically
for use in connection with the preparation of such Registration Statement,
prospectus, amendment or supplement; provided, however, that the indemnity
                                     --------  -------
contained in this section shall not apply to amounts paid in settlement of any
such claim, loss, damage, liability or action if such action is effected without
the consent of the applicable Stockholder (which consent shall not be
unreasonably withheld); provided, further, that the obligations of a Stockholder
                        --------  -------
hereunder shall be limited to an amount equal to the net proceeds to such
Stockholder of Registrable Shares sold in connection with such registration.

                 (c)    Each party entitled to indemnification under this
Section 2.5 (the "Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit

                                      -10-
<PAGE>

the Indemnifying Party to assume the defense of any such claim or any litigation
resulting therefrom; provided, that counsel for the Indemnifying Party, who
                     --------
shall conduct the defense of such claim or litigation, shall be approved by the
Indemnified Party (whose approval shall not be unreasonably withheld); and,
provided, further, that the failure of any Indemnified Party to give notice as
- --------  -------
provided herein shall not relieve the Indemnifying Party of its obligations
under this Section 2.5 except to the extent that the Indemnifying Party is
adversely affected by such failure. The Indemnified Party may participate in
such defense at such party's expense; provided, however, that the Indemnifying
                                      --------  -------
Party shall pay such reasonable expense 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 the Indemnified Party and
any other party represented by such counsel in such proceeding; provided,
                                                                --------
further, that in no event shall the Indemnifying Party be required to pay the
- -------
expenses of more than one law firm per jurisdiction as counsel for the
Indemnified Party. The Indemnifying Party also shall be responsible for the
reasonable expenses of such defense if the Indemnifying Party does not elect to
assume such defense. 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 of such claim or
litigation, and no Indemnified Party shall consent to entry of any judgment or
settle such claim or litigation without the prior written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld.

                 (d)    In order to provide for just and equitable contribution
in circumstances in which the indemnification provided for in this Section 2.5
is due in accordance with its terms but for any reason is held to be unavailable
to an Indemnified Party in respect any losses, claims, damages and liabilities
referred to herein, then the Indemnifying Party shall, in lieu of indemnifying
such Indemnified Party, contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages or liabilities to
which such party may be subject in such proportion as is appropriate to reflect
the relative fault of the Company on the one hand and the Stockholders on the
other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Company and the Stockholders shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of material fact related to information supplied by the Company
or the Stockholders and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Stockholders agree that it would not be just and equitable
if

                                      -11-
<PAGE>

contribution pursuant to this Section 2.5 were determined by pro rata allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to above. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

     Any party entitled to contribution will, promptly after receipt of notice
of commencement of any action, suit or proceeding against such party in respect
of which a claim for contribution may be made against another party or parties
under this Section, notify such party or parties from whom contribution may be
sought, but the omission so to notify such party or parties from whom
contribution may be sought shall not relieve such party from any other
obligation it or they may have thereunder or otherwise under this Section.  No
party shall be liable for contribution with respect to any action, suit,
proceeding or claim settled without its prior written consent, which consent
shall not be unreasonably withheld.

          2.6    Other Matters with Respect to Underwritten Offerings.  In the
                 ----------------------------------------------------

enter into an underwriting agreement containing customary representations and
warranties with respect to the business and operations of the Company and
customary covenants and agreements to be performed by the Company, including
without limitation customary provisions with respect to indemnification by the
Company of the underwriters of such offering; (b) use its reasonable best
efforts to cause its legal counsel to render customary opinions to the
underwriters with respect to the Registration Statement; and (c) use its

Company as to its compliance with the reporting requirements of said Rule 144(c)
of the Securities Act and 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, and such other reports and documents so filed
by the Company as the Stockholder may reasonably request in complying with any
rule or regulation of the SEC allowing the Stockholder to sell any such
securities without registration.

          ------------------------
any part of the Premises or the Headleased Premises are destroyed or damaged by
fire or other casualty or taken by eminent domain, and either Sublandlord or

                                   HEADLEASE

     6.1  Sublease Subject to Headlease.  This Sublease is subject to the
          -----------------------------
Headlease.  Subject to this Section 6.1, all terms and conditions of the
Headlease are incorporated into and made a part of this Sublease as if
Sublandlord were the landlord thereunder and Subtenant were the tenant.  In case
of conflict between the incorporated provisions of the Headlease and the
remaining provisions of this Sublease, the latter shall control.  Subtenant
assumes and agrees to perform the tenant's obligations under the Headlease
during the Term, except that the obligation to pay rent or other amounts to
Headlandlord under the Headlease shall not be an obligation of Subtenant, and
Subtenant shall instead pay the rent under this Sublease.  Subtenant shall not
commit or suffer any act or omission that will violate any of the provisions of
the Headlease.

          If the Headlease terminates as a result of a default or breach of
Subtenant under this Sublease and/or the Headlease, then the Subtenant shall be
liable to the Sublandlord for the direct damage suffered as a result of such
termination.  Subtenant covenants not to commit or suffer any act or omission
that will violate the Headlease.

     6.2  Excluded Obligations.  Notwithstanding anything to the contrary
          --------------------
herein, the incorporated provisions of the Headlease are amended or qualified as
follows:

     i.   Sublandlord shall not be liable under any circumstances for a loss of
or injury to property, or interference with Subtenant's business, however
occurring, incidental to any failure to furnish any utilities or services.

     ii.  Sublandlord shall have no responsibility to perform or construct (or
to pay the cost of performing or constructing) any repair, maintenance or
improvement in or to the Premises, except as specifically set forth in Section
2.1 of this Sublease.

     iii. Rent shall be abated under this Sublease only to the extent that
Sublandlord receives a corresponding rent abatement under the Headlease.

     iv.  Wherever the Headlease grants to Sublandlord a grace or cure period,
the corresponding grace or cure period under this Sublease shall be two (2)
business days shorter in duration.

     The parties acknowledge that Sublandlord's ability to satisfy certain of
its obligations to Subtenant under this Sublease is contingent upon the full and
timely performance of Headlandlord's obligations under the Headlease.  The
parties further acknowledge that, while Sublandlord will use reasonable efforts
to cause Headlandlord to perform its obligations under the Headlease,
Sublandlord will not be liable to Subtenant for any breach of Sublandlord's
obligations under this Sublease, nor shall such breach diminish Sublandlord's
rights hereunder, where the same is caused by or attributable to the failure of
Headlandlord to perform its obligations under the Headlease.

Headlease.

          ------------------------
the Headlease pursuant to its terms or the Headlease otherwise terminates or
expires, this Sublease shall likewise and simultaneously terminate.

The Security Deposit shall be held by Sublandlord without interest and
Sublandlord shall be entitled to commingle the Security Deposit with its other

     7.6  Construction.  If any term, covenant, condition or provision of this
          ------------
Sublease or the application thereof to any person or circumstances shall be
declared invalid or unenforceable by the final ruling of a court of competent
jurisdiction having final review, the remaining terms, covenants, conditions and
provisions of this Sublease and their application to persons or circumstances
shall not be affected thereby and shall continue to be enforced and recognized
as valid agreements of the parties.

     This Sublease constitutes the entire agreement between the parties hereto
with respect to the transactions contemplated herein, and it supersedes all
prior discussions, understandings or agreements, including without limitation
the Offer To Sublease, between the parties.

     There are no oral or written agreements between Sublandlord and Subtenant
affecting this Sublease.  This Sublease may be amended, and the provisions
hereof may be waived or modified, only by instruments in writing executed by
Sublandlord and Subtenant.

     The titles of the several Articles and Sections contained herein are for

that Subtenant is not in default in the performance or observance of any of the
terms and

                                       10
<PAGE>

provisions of this Sublease or the Headlease, if Sublandlord intends during the
Term of this Sublease, to market the Second Floor Space of 120 Flanders Road
consisting of approximately 18,111 rentable square feet when it becomes
available for leasing (the "Second Floor Space"), then Sublandlord will present
a term sheet (the "Offer") for the leasing of the Second Floor Space to
Subtenant. Except as otherwise set forth in the Offer, the lease of the Second
Floor Space shall be on the terms and conditions set forth in this Sublease.

Upon its receipt of the Offer, Subtenant shall have seven (7) business days to
accept or reject the Offer.  If Subtenant accepts the Offer within said seven
day period, Sublandlord and Subtenant shall execute a lease for such Second
Floor Space on the terms set forth in the Offer within thirty (30) days of
Subtenant's acceptance of the Offer.  In the event Subtenant does not accept the
Offer within said seven day period or Sublandlord and Subtenant do not execute a
lease on the terms set forth in the Offer within said thirty day period, then
Sublandlord shall have the right to lease the Second Floor Space on terms which
Sublandlord reasonably determines to be at least 90% as economically beneficial
to Sublandlord as those set forth in the Offer without reoffering the Second
Floor Space to Subtenant.  If (i) Sublandlord wishes to lease the Second Floor
Space on terms less than 90% as economically beneficial to Sublandlord, or (ii)
Sublandlord does not enter into a lease for the Second Floor Space within 180
days of the submission of the Offer to Subtenant, then the Second Floor Space
shall first be subject to re-submission to Subtenant pursuant to the terms of
this Section prior to Sublandlord's leasing of the same.

In the event Subtenant accepts the Offer to lease the Second Floor Space,
Subtenant shall be solely responsible for any and all costs associated with
relocating or moving Subtenant from the Premises to the Second Floor Space.

     7.8  Access and Security.  Normal Building hours shall be from 7:00 a.m. to

access system.  Subtenant shall be responsible for its own security card access
at the entrance to the Premises.

     7.9  Cafeteria.  Subtenant shall have the right to use the cafeteria at 120
          ---------
Flanders Road during the Term of this Sublease.

     7.10 Option to Extend.  Subtenant shall have the right and option to extend
          ----------------
the Term for an additional two (2) years and nine (9) months until September 30,
2005 (the "Extension Term") commencing upon the expiration of the original Term
referred to in Section 2.2 (the "Original Term"), provided that Subtenant shall
give Sublandlord notice of Subtenant's irrevocable exercise of such option at
least ninety (90) days prior to the expiration of the Original Term and provided
further that Subtenant shall not be in default at either the time of giving such
notice or at the time of the commencement of the Extension Term in the
performance or observance of any of the terms and

                                       11
<PAGE>

provisions of this Sublease on the part of Subtenant to be performed or
observed. Prior to the exercise by Subtenant of such option, the expression
"Term" shall mean the Original Term, and after the exercise by Subtenant of such
option, the expression "Term" shall mean the Original Term as it has been
extended by the Extension Term. Except as expressly otherwise provided in the
following paragraph, all the terms, covenants, conditions, provisions and
agreements in the Sublease contained shall be applicable to the Extension Term.
If Subtenant shall give notice of its exercise of such option to extend in the
manner and within the time period provided aforesaid, the Term shall be extended
upon the giving of such notice without the requirement of any further action on
the part of either Subtenant or Sublandlord. If Subtenant shall fail to give
timely notice of the exercise of such option as aforesaid, Subtenant shall have
no right to extend the Term of this Sublease, time being of the essence of the
foregoing provisions.

The Monthly Fixed Rent payable during the Extension Term shall be the greater of
(i) the Monthly Fixed Rent in effect for the year immediately preceding the
commencement of the Extension Term or (ii) the Fair Market Rent for the
Premises, as determined below, as of the commencement of the Extension Term.  If
for any reason the Monthly Fixed Rent payable during the Extension Term has not
been determined as of the commencement of the Extension Term, Subtenant shall
pay the Monthly Fixed Rent payable during the immediately preceding year until
the Monthly Fixed Rent for the Extension Term is determined, at which time, an
appropriate adjustment, if any, shall be made.

For purposes hereof, the Fair Market Rent shall mean the fair rent for the
Premises as of the commencement of the Extension Term under market conditions
then existing.  Fair Market Rent shall be determined by agreement between
Sublandlord and Subtenant, but if Sublandlord and Subtenant are unable to agree
upon the Fair Market Rent at least two (2) months prior to the date upon which
the Fair Market Rent is to take effect, then the Fair Market Rent shall be
determined by appraisal made as hereinafter provided by a board of three (3)
reputable independent commercial real estate consultants, appraisers, or
brokers, each of whom shall have at least ten (10) years of experience in the
Westboro office rental market and each of whom is hereinafter referred to as
"Appraiser".  Subtenant and Sublandlord shall each appoint one such Appraiser
and the two (2) Appraisers so appointed shall appoint the third Appraiser.  The
cost and expenses of each Appraiser appointed separately by Subtenant and
Sublandlord shall be borne by the party who appointed the Appraiser.  The cost
and expense of the Third Appraiser shall be shared equally by Subtenant and
Sublandlord.  Sublandlord and Subtenant shall appoint their respective
Appraisers at least fifty-five (55) days prior to commencement of the Extension
Term and shall designate the Appraisers so appointed by notice to the other
party.  The two Appraisers so appointed and designated shall appoint the third
Appraiser at least forty-five (45) days prior to the commencement of the
Extension Term and shall designate such Appraiser by notice to Sublandlord and
Subtenant.  The board of three (3) Appraisers shall determine the Fair Market
Rent of

                                       12
<PAGE>

the Premises as of the commencement of the Extension Term and shall notify
Sublandlord and Subtenant of their determinations at least thirty (30) days
prior to the commencement of the Extension Term. If the determination of the
Fair Market Rent of any two (2) or all three (3) Appraisers shall be identical
in amount, said amount shall be deemed to be the Fair Market Rent of the
Premises. If the determination of all three (3) Appraisers shall be different in
amount, the average of the two (2) values nearest in amount shall be deemed the
Fair Market Rent of the Premises. The Fair Market Rent of the Premises
determined in accordance with the provisions of this Section shall be binding
and conclusive on Subtenant and Sublandlord.

     7.11 Consent of Headlandlord.  Subtenant acknowledges that this Sublease is
          -----------------------
subject to the consent of the Headlandlord.  Within three (3) business days
after the execution of this Sublease, Sublandlord shall notify and forward an
originally executed copy of this Sublease to the Headlandlord and shall request
Headlandlord's consent thereto.  Upon receiving Headlandlord's response,
Sublandlord shall notify Subtenant as to whether or not the Headlandlord
consented to the sublease.  In the event the Headlandlord does not consent to
the sublease, this Sublease shall terminate and be of no further force or
effect.

     THIS SUBLEASE is executed as a sealed instrument in two or more
counterparts on the day and year first above written.

                              EMPLOYMENT AGREEMENT
                              --------------------


     This Employment Agreement (the "Agreement"), made this 1st day of December
1999 is entered into by and between Switchboard Incorporated, a Delaware
corporation (the "Company"), and Dean Polnerow (the "Employee").

     1.   Title; Capacity.  The Employee shall serve as President, or in such
          ---------------
other position as the Company or its Board of Directors (the "Board") may
determine from time to time.  The Employee shall be subject to the supervision
of, and shall have such authority as is delegated to him by, the Board or such
officer of the Company as may be designated by the Board.

     The Employee hereby accepts such employment and agrees to undertake the
duties and responsibilities inherent in such position and such other duties and
responsibilities as the Board or its designee shall from time to time reasonably
assign to him.  The Employee agrees to devote his entire business time,
attention and energies to the business and interests of the Company while
employed by the Company.

     2.   At-Will Employment.  The Employee shall be employed on an at-will
          ------------------
basis, which means either party may terminate the employment relationship at any
time, for any reason or no reason, and with or without notice.

     3.   Compensation and Benefits.
          -------------------------

          3.1  Salary.  The Company shall pay the Employee a base salary at the
               ------

equal bi-weekly

                                      -1-
<PAGE>

installments, consistent with the Company's regular payroll procedures.
Employee's salary shall be subject to adjustment, as determined by the Board.

          3.2  Bonus.  The Employee shall be eligible to receive an annual bonus
               -----
of up to sixty thousand dollars ($60,000) for the one-year period beginning on
January 1, 1999, in the event that Employee meets certain criteria as set forth
in the Employee's 1999 Executive Incentive Plan.  The Employee shall also be
eligible to receive an additional annual bonus for the same one-year period of
up to thirty-five thousand dollars ($35,000) in the event that he substantially
surpasses achievement of the criteria, as set forth in the 1999 Executive
Incentive Plan.   Such bonuses shall be subject to adjustment thereafter as
determined by the Board.

          3.3  Benefits.  The Employee shall be entitled to participate in all
               --------
benefit programs that the Company establishes and makes available to its
employees, if any, to the extent that Employee's position, tenure, salary, age,
health and other qualifications make him eligible to participate.  The Employee
shall also be entitled to receive life insurance coverage an amount equal to
five times Employee's base salary (or $825,000 as of the date hereof) with the
Company to pay all applicable premiums.  All increases in the amount of life
insurance, based upon upward adjustments in Employee's salary, are subject to
the Company's ability to obtain additional coverage.

     4.   Change in Control.

Employee shall have failed during such thirty (30) day period to resume the
diligent performance of his duties.  If Employee, in good faith, disputes
Switchboard's determination that he has not so resumed the diligent performance
of his duties, the parties agree to submit such dispute to arbitration in

Switchboard, at the Employee's then current contribution rate for such benefits
for a period of up to six months commencing on the effective date of Employee's

          5.1  Termination by Switchboard.  Switchboard shall provide the
               --------------------------
Employee with the benefits set forth in Section 6 upon termination by
Switchboard of the Employee's employment at any time during the term of this
Agreement for reasons other than termination for "cause."  For the purposes
hereof, "cause" shall be defined as the willful and repeated failure of the
Employee to perform substantially his duties, or action by the Employee
involving willful misfeasance, gross negligence or the commission of any
felonious action; provided, however, that termination for cause shall not be
effective unless the Employee shall have received written

                                      -5-
<PAGE>

notice from Switchboard of such failure (specifying in detail the facts and
circumstances on which Switchboard is relying) and a demand for substantial
performance thirty (30) days prior to such termination, and Switchboard
determines that the Employee shall have failed during such thirty (30) day
period to resume the diligent performance of his duties. If Employee, in good
faith, disputes Switchboard's determination that he has not so resumed the
diligent performance of his duties, the parties agree to submit such dispute to
arbitration in accordance with the provisions of Section 12 below.

          5.2  Termination by Employee.  Switchboard shall provide the Employee
               ------------------------
with the benefits set forth in Section 6 upon termination by the Employee of the
Employee's employment with Switchboard at any time during the term of this
Agreement if the Employee elects to resign within 90 days of either of the
following events:

               (i)  The Employee's job is relocated more than 35 miles from
     Westboro, Massachusetts; or

               (ii) The Employee's job title and/or overall targeted cash
     compensation are materially reduced from levels in effect at the
     commencement of the initial or any renewal term of this Agreement.

          5.3  Notice of Termination.  Any termination of the Employee's
               ---------------------
employment by Switchboard or by the Employee as referred to in this Section
shall be communicated by written notice of termination to the other party.

     6.   Termination Benefits.  Subject to and in accordance with the
          --------------------
provisions set forth in Section 5, and further subject to the execution of a
mutually agreeable release agreement, the following benefits (subject to any
applicable taxes required to be withheld) shall be paid to the

                                      -6-
<PAGE>

Employee as follows:

          (a) Compensation.  The Employee will be paid his base salary for a
              ------------
period of six months from the effective date of his termination (the
"Continuation Period"), in the event that the Employee remains unemployed during
the Continuation Period.  If the Employee obtains other employment during the
Continuation Period, any salary continuation will cease unless the Employee's
new employment is at a base salary lower than his base salary under Section 3.1,
in which case the Company will pay the Employee the difference between his base
salary under Section 3.1 and his new base salary during the Continuation Period.

          (b) Insurance Benefits, etc.  The Employee's participation (including
              ------------------------
dependent coverage) in the life, health and dental insurance plans (excluding
further participation in the existing 401K Plan) of Switchboard in effect
immediately prior to the effective date of Employee's termination shall be
continued, or equivalent benefits provided, by Switchboard, at the Employee's
then current contribution rate for such benefits for a period of up to six
months commencing on the effective date of Employee's termination in the event
that the Employee remains unemployed during the Continuation Period.  If
Employee obtains other employment during the Continuation Period, any continuing
benefits will cease.

     7.   Continuing Obligations.  In order to induce Switchboard to enter into
          ----------------------
this Agreement, the Employee hereby ratifies and confirms his Invention and Non-
Disclosure Agreement with Switchboard.  Without limiting the generality of the

the following due to causes which are attributable to Exodus or Exodus Third
Parties, and not as a result of any actions of Customer (including Customer
Equipment) or third parties other than Exodus Third Parties, Exodus will, upon
Customer's request in accordance with paragraph (iii) below, credit Customer's
account as described below. For

         Confidential materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.

          (b)  the purposes of this Agreement, "Exodus Third Parties" shall mean
third parties from which Exodus procured services or equipment in the delivery
of the Internet Data Center Services.

               (i)   Inability to Access the Internet (Downtime). If Customer is
unable to transmit and receive information from Exodus' Internet Data Centers
(i.e., Exodus' LAN and WAN) to other portions of the Internet for more than
[**]due to causes which are attributable to Exodus or Exodus Third Parties
(excluding causes attributable to Customer or other third parties, other than
Exodus Third Parties, Exodus will credit Customer's account the pro-rata total
service charges for [**] of service. If such event continues for an additional
[**], Exodus will credit Customer's account the pro-rata total service charges
for [**] of service, and for each additional [**] of service, up to an aggregate
maximum credit of total service charges for [**] of service in any [**]. Exodus'
scheduled maintenance of the Internet Data Centers and Internet Data Center
Services shall not be deemed to be an event for which a remedy is available
pursuant to this Section 5.2(a)(i). For purposes of the foregoing, unable to
transmit and receive" shall mean sustained packet loss averaging in excess of
[**] over such [**] or [**] period, as applicable, based on Exodus'
measurements. Exodus will, upon Customer's request provide Customer with
evidence of measurements reasonably acceptable to Customer to demonstrate the
existence and amount of any packet loss incurred by Customer and caused by
Exodus or Exodus Third Parties.

               (ii)  Packet Loss and Latency. Exodus does not proactively
monitor the packet loss or transmission latency of specific customers. Exodus
does, however, proactively monitor the aggregate packet loss and transmission
latency within its LAN and WAN. In the event that Exodus discovers (either from
its own efforts or after being notified by Customer) that Customer is
experiencing packet loss in excess of [**] percent ([**]) ("Excess Packet Loss")
or transmission latency in excess of [**] round trip time (based on Exodus' good
faith measurements) between any two Internet Data Centers within Exodus' U.S.
network (collectively, "Excess Latency", and with Excess Packet Loss "Excess
Packet Loss Latency"), and in the case where Customer discovers such condition,
Customer notifies Exodus, Exodus will take all actions necessary to determine
the source of the Excess Packet Loss/Latency.

                     (A)  Time to Discover Source of Excess Packet Loss/Latency;
Notification of Customer. Within [**] of discovering the existence of Excess
Packet Loss/Latency, Exodus will determine whether the source of the Excess
Packet Loss/Latency is limited to the Customer Equipment and the Exodus
equipment connecting the Customer Equipment to Exodus' LAN ("Customer Specific
Packet Loss Latency"). If the Excess Packet Loss/Latency not a Customer Specific
Packet Loss/Latency, Exodus will determine the source of the Excess Packet
Loss/Latency within [**] after determining that it is not a Customer Specific
Packet Loss/Latency. In any event, Exodus will notify Customer of the source of
the Excess Packet Loss/Latency within [**] after identifying the source.

     In addition to the foregoing, Exodus shall (1) notify Customer of any
Excess Packet Loss or Excess Latency discovered within Exodus' LAN or WAN
tenable Customer to determine whether same is affecting the Customer Equipment,
if Exodus reasonably believes that the problem uniquely affects Customer; and
(2) if Customer reasonably believes that it is entitled to a credit pursuant to
Sections 5.2(a)(i) or (ii) and requests such information in writing, Exodus
shall provide a written analysis of network performance to the extent same is
tracked b, Exodus and is relevant to validating the applicability and amount of
such credit.

                     (B)  Remedy of Excess Packet Loss/Latency. If the Excess
Packet Loss/Latency remedy is due to causes attributable to Exodus or Exodus
Third Parties (excluding causes attributable to Customer or other third parties
other than Exodus Third Parties), Exodus will remedy the Excess Packet
Loss/Latency within [**] of determining the source of the Excess Packet
Loss/Latency. If the Excess Packet Loss/Latency is partly or wholly within the
control of third parties other than Exodus Third Parties, Exodus will notify
Customer and will use commercially reasonable efforts to notify the party(ies)
responsible for the source and cooperate with it (them) to resolve the problem
as soon as possible.

                     (C)  Failure to Determine Source and/or Resolve Problem. In
the event that Exodus is unable to determine the source of and remedy the Excess
Packet Loss/Latency within the time periods described above (other than for
causes which are attributable to third parties other than Exodus Third Parties),
Exodus will credit Customer's account the pro-rata total service charges for
[**] of service for every [**] after the time periods described above that it
takes Exodus to resolve the problem, up to an aggregate maximum credit of total
service charges for [**] of service in any [**].

         Confidential Materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.

               (iii) Customer Must Request Credit. To receive any of the credits
described in this section 5.2(a), Customer must notify Exodus within [**] from
the time Customer becomes eligible to receive a credit. Failure to comply with
this requirement will forfeit Customer's right to receive a credit.

               (iv)  Remedies Shall Not Be Cumulative; Maximum Credit. In the
event that Customer is entitled to credits pursuant to both Sections 5.2(a)(i)
and 5.2(a)(ii) arising from the same event, such credits shall not be cumulative
and Customer shall be entitled to receive only the maximum single credit
available for such event. In no event will Exodus be required to credit Customer
in any one (1) calendar month total service charges in excess of [**] of
service. Customer shall not be eligible to receive any credits for periods in
which Customer received any Internet Data Center Services free of charge (not as
a result of a credit under this Section 5.2).

               (v)   Termination Option for Chronic Problems. If, in any single
calendar month, Customer would be able to receive credits totaling [**]
resulting from [**] or more events during such calendar month or, if any single
event entitling Customer to credits under paragraph 5.2(a)(i) exits for a period
of [**], then Customer may terminate this Agreement for cause and without
penalty by notifying Exodus within five (5) days following the end of such
calendar month. Such termination will be effective in not less than ten (10)
days and not more than sixty (60) days after receipt of such notice by Exodus.

to perform the Internet Data Center Services from such location as contemplated
by this Agreement; (ii) it has full right, power and authority to enter into
this Agreement and to perform the acts required of it hereunder; (iii) the
execution of this Agreement by Exodus and the performance by Exodus of its
obligations and duties hereunder, does not and will not violate any agreement to
which Exodus is a party or by which it is otherwise legally bound; and (iv)
Exodus' Internet Data Center Services, and facilities used by Customer pursuant
to this Agreement (A) do not as of the Installation Date, and will not during
the term of this Agreement be provided or operate in any manner that would
violate any applicable law or regulation; and (B) as of the submission date,
comply with the description of the facility systems attached hereto as Exhibit
D. Exodus covenants that during the term of this Agreement Exodus will not alter
the facilities systems it uses such that Customer would receive materially
reduced benefits (as reasonably determined by Customer in consultation with
Exodus) from Exodus facilities systems as described in Exhibit D. If Exodus
breaches the warranties and covenants in this Section 5.2(b) and fails to cure
any such breach within the time period provided in Section 8, below, Customer's
sole remedy shall be its ability to terminate this Agreement effective in not
less than ten (10) days and not more than sixty (60) days after (receipt of
written notification from Customer. The foregoing limitation shall not release
Exodus of any of its obligation pursuant to Section 7.1 (Indemnification),
below.

BANDWIDTH REPORTS

Part Number

EXO-SRBW

Description

Exodus Bandwidth Reports provide customers with graphical and tabular statistics
of their bandwidth usage.  Reports are accessible via the web and show traffic
volumes between the customer's equipment and the network In addition to
providing the traffic volume at a particular instance in time, the reports
include summary statistics of maximum, minimum, and 95% loading.  This
information offers customer a way to monitor usage trends and assist with the
capacity planning of server and network resources.

Reports

Monthly

Monthly reports are included with each network service purchased.  Monthly
reports are produced on the 16th and 1st of the month.  On the 16th of the month
the report lists usage for each of the prior 15 days.  On the 1st of the month,
the report provides bandwidth usage for the prior month.

Daily

Daily reports are made available each day of the month.  Reports for the
previous day are available by 4:00 AM PDT the following morning.  Daily Reports
are ordered as an optional service using the part number shown above.

Both the Monthly and Daily Reports feature:

 .  A summary table which gives overall traffic statistics (e.g., max and min
   throughput) for the period covered

 .  Graphical plots of bandwidth statistics

 .  Data detail shown in a tabular format

The Monthly Reports are archived and available for 12 months.

Media

Bandwidth reports are published on the web.  To ensure confidentiality of
customer data, access to individual customer information requires the user to
enter a user-id and password.  Report data can also be downloaded from a
browser, allowing the customer to use a spreadsheet to do customized
calculations or graphs.

Measured Statistics

For each network line, the Bandwidth Reports capture statistics on the output,
input, and total data flow.  Output is defined as the amount of data passing
from the server to the network.  Input is the volume of traffic from the network
to the server.  Total is the sum of the input and output.  Below is a list of
the reported statistics for data output, input, and total:

 .  Bandwidth -The volume of data in Kbits/sec

 .  Minimum - The lowest measured bandwidth

                                      -16-
<PAGE>

 .   Maximum - This highest measured bandwidth

 .   95% Value -Network bandwidth is lower than or equal to this value 95% of the
    time. This statistic is only reported for customers with usage based billing
    (not flat rate).

Usage Based Billing

Exodus Communications will bill the customer monthly for the base bandwidth
amount that has been purchased.  For bandwidth used above the base amount there
will be an additional per megabit used charge (refer to the quote), which will
be billed at the end of the month.  Exodus uses the 95th percentile measurement
rule to calculate the additional bandwidth used above the base amount.

95th Percentile Measurement Rule

The Exodus Bandwidth measurement system collects five minute averages of the
total (input + output) line usage of your co-location network connection.  This
data is collected seven days a week, twenty-four hours a day for each month.  At
the end of each month or billing cycle the top five percent of these data points
are discarded.  The highest remaining data point (five minute average) is
referred to as the 95th percentile.  The 95th percentile value less the base
bandwidth purchased determines the additional bandwidth used.  The additional
usage charge is calculated as follows:

Additional usage charge = additional bandwidth used X additional per megabit
used charge

Decimal fractions of a megabit are included with the additional bandwidth used
measurement

Example

Assume a usage based 10Mbps Ethernet connection with the following parameters:

 .  The monthly 95th percentile utilization is 4.6 Mbps

 .  Base bandwidth purchased at $2000 per month for 2 Mbps

 .  Additional per megabit charge for bandwidth used above 2 Mbps at $1300 per
   megabit

          Problem Resolution  When a Network Control Center Engineer is unable to resolve a
                      Prices  network problem within a specified time period, based on the
                              Request Priority, she forwards the problem to the Network
                              Engineering group for resolution.

                              When the Network Engineering group is unable to resolve a network
                              problem, they escalate the problem to the Exodus Backbone Engineering
                              Department. The Backbone Engineers are responsible for the design,
                              development, and implementation of the Exodus backbone network and
                              network infrastructure.

                              When a NCC Engineer is unable to resolve a system problem
                              within a specified time period, based on the Request Priority,
                              she forwards the problem to the System Administration group for
                              resolution.
- -------------------------------------------------------------------------------------------------------------
                Escalation -  In addition to escalating problems for technical resolution, Exodus
           Exodus Management  has a management escalation procedure to ensure that all possible
                              resources are being applied to resolve critical customer problems.
                              This escalation path includes the following people:
                              .   Lead NCC Engineer
                              .   NCC Manager
                              .   Internet Data Center Manager
                              .   Manager, Customer Advocacy
                              .   Vice President, Customer Service
                              .   President of Exodus
- -------------------------------------------------------------------------------------------------------------
                Escalation -  While we make every effort to ensure that problems area being resolved as
                Initiated by  quickly as possible, we understand that at certain times, you may want us
                The Customer  to go faster.

                              At any point during the problem resolution process, you can ask the person
                              you are talking with to escalate the problem to the next level.

                              Example:  If you are talking to a NCC Engineer, you can ask to escalate the
                                        problem to the Lead NCC Engineer.  You may also ask to escalate a
                                        problem to the people in the management escalation process
                                        described above.

           Standard Requests  Requests for configuration changes, additional services or information are
                              most efficiently made by E-mail so that any requirements are documented.

                              Exodus established a set of Service Level Commitments for these standard
                              requests, which are described in the next section.

       Customer Satisfaction  When each Customer Request Call Ticket is closed after resolution, we
                      Survey  E-mail you a short survey form, asking for your feedback on how well we did
                              in resolving your request.

                              We thank you in advance for completing and returning these surveys, which
                              are used to evaluate how well we respond to your requests and to identify
                              opportunities to improve our services.

EXODUS INFRASTRUCTURE

Part of the Exodus Solutions strategy is engineering and maintaining a superior
infrastructure to support continuous Internet operations.  To achieve this goal,
we have made heavy investments in the infrastructure of both our facilities and
our network.  Exodus' infrastructure consists of two major components:
nationwide

                                      -33-
<PAGE>

Internet Data Centers and a high-speed Internet backbone. Our infrastructure
design is based upon two key principles:

1.  Engineer each Internet Data Center to eliminate any single point of failure

2.  Reduce the distance from the Web surfer to the information on the Web by
combining world-class Internet Data Centers with a reliable high-speed Internet
backbone engineered solely for distribution of data.

Internet Data Center Description

Our state-of-the-art Internet Data Centers provide the reliable, redundant and
high-performance infrastructure demanded by today's mission-critical Internet
systems.

Exodus maintains a virtually endless stream of power through our Redundant Power
Management System (RPMS).  Under this system, all co-location customers and
critical systems receive clean, conditioned power from the UPS batteries.  The
RPMS UPS consists of multiple UPS systems maintained at a load not to exceed
75%; in the event one fails, the remainder can take on the load without
exceeding capacity.  The batteries are charged either by utility power or by an
on-site backup generator.  Additionally, we have a secondary generator on site
to provide backup to the primary generator.  It can be hooked via umbilical cord
feed to supply the UPS systems.  On a more specific level, all our customers
receive dedicated circuit breaker protection.

If the utility power fails, our generator maintenance contractors dispatch
generator technicians, spare parts and diesel fuel to replenish the generators,
giving Exodus the ability to run our Internet Data Centers indefinitely.  By
implementing the power management system, we can move from utility to generator
power without observing any spike or fluctuation of electricity to our co-
located customers.

Each Exodus facility is built on raised floors and has seismically-braced racks,
cabinets and cages for protection against earthquakes.  Furthermore, all
Internet Data Centers have high-volume, zoned temperature control systems.  As
with the redundant power systems, Exodus has multiple Liebert 15-ton air
conditioning units, for a combined total of 75 tons of air condition output to
ensure proper heat dissipation.  In the event one system fails, the other units
are able to assume the full load of cooling the co-located equipment.

In addition, Exodus has built a Redundant Fire Suppression System consisting of
smoke and heat sensors that trigger automatic fire department notification.  The
primary system - an environmentally safe, gas-based Fire Master (FM200) fire
extinguishing system - is designed to eliminate a fire disaster but be harmless
to the systems co-located at the Internet Data Centers.  As a backup, the
secondary system is a dry-pipe sprinkler system.

Each Internet Data Center also has a "nerve center" called the Network Control
Center (NCC).  The entire facility, network and customer systems are carefully
monitored and managed by the NCC staff, available on a 24-hour basis via the
Exodus 1-800 Support Line.  The NCC staff is assisted by expert network and
system engineers who can provide escalation support when needed.

To monitor the activity on each system in our Internet Data Centers, we have
implemented Computer Associates' Unicenter(TM) TMG network management platform
to facilitate the monitoring of our complete LAN and WAN.  Unicenter TNG allows
us to monitor specific server processes at an 0/S network and application level
and take action on events created by these processes.  Such actions might
include the start and restart of a process or even the sending of a page alert
to a customer.

In each Internet Data Center, Exodus has installed fiber optic cable from
various providers such as PacBell, TCG, ICG, MFS and Brooks Fiber, allowing
redundant fiber connections out to the IXPs.  In this way, we eliminate any
single point of failure between our Internet Data Centers and the Internet.

The security and integrity of each Internet Data Center is maintained by video
surveillance cameras and security breach alarms with automatic police
notification and 24-hour personnel.  There are several cameras mounted inside
and outside the facility and monitored by on-site personnel.

As a co-location customer, you are allowed 24-hour access to the facility
through a secure card key access system.  This system allows only designated
company personnel physical access to our Internet Data Centers.

                                      -34-
<PAGE>

The physical environment of the Internet Data Centers allows for flexibility of
space depending upon how many servers customers wish to co-locate at our
facilities.  For example, you can purchase a Virtual Data Center, a seven-by-
eight foot cage, for large applications.  An alternative option for those not
requiring a large block of space but needing added security is an enclosed,
dedicated cabinet.  The cabinet provides a full rack's worth of space and is
also under lock and key.  If you are unsure of anticipated growth and looking
for an entry point, Exodus provides space in quarter-rack increments in our
common co-location area where multiple servers are housed on racks in a single
cage.

No matter what amount of space you require, Exodus is committed to helping you
manage your transition into our facility.  Our Project Managers advise on and
facilitate the logistics involved in moving to our facility, such as ordering
new DNS registration, IP address allocation or DNS transition from another
provider.

In addition to the standard services, our support team can provide various
levels of system-related services, from tape backup to full systems and
applications management.


               THE EXODUS NETWORK: PROVIDING THE FOUNDATION FOR
                           INFORMATION DISTRIBUTION


Fundamental to our ability to provide the shortest and most reliable paths from
Web users to our customers' Internet sites is our Open Peering Policy, which
drives us to seek peering agreements with as many providers as possible.  In
fact, we peer with over 80 National and Regional Internet Providers at the
Internet Exchange Points (IXPs)-such as PB-NAP, MAE-West, MAE-East, MAE-LA and
CIX- more than any other Internet service company.  We have recently established
private multi-location peering with three National Backbone Providers, so we can
balance Internet traffic between IXPs and private peering links.

Exodus' network model can guarantee uninterrupted Internet operations, unlike
Inter-net Service Providers' (ISPs) networks, which aren't designed for Internet
commerce.  Our distributed network design is crucial to businesses who rely on
the Web, such as online service providers, information publishers, entertainment
outlets and transaction processing providers, as well as electronic storefronts.
For these companies and others like them, continuous Internet access is mission-
critical to best serve their customers.

Traditional ISPs cannot effectively or efficiently support the needs of these
businesses.  Why? Because their networks are designed around end-user Internet
access- which means the data being distributed is not always located near the
user and may therefore need to travel a significant distance over networks to
reach its destination.  Exodus' network, on the other hand, is designed for
content distribution and pushes data out to major Internet Exchange Points
(IXPs), where it is interchanged between networks in order to get to end-users
faster and more reliably.

To complement our network design, we established our first Internet Data Center
in Northern California, where three of the six major IXPs in the United States
are located.  This Internet Data Center has set the standards by which all of
our subsequent Internet Data Centers are modeled.  Not surprisingly, our second
Internet Data Center was founded in Jersey City, New Jersey, close to the
second-largest concentration of IXPs in the United States.  To keep up with
customer demand, Internet Data Centers have been built and opened in Seattle,
Irvine, Washington D.C.  and Boston.  Future facilities are also planned for
Europe and the Pacific Rim.

Beyond providing high-availability Internet connections, the Exodus network also
offers reliable and scalable bandwidth options.  In contrast to ISPs, who
commonly over-subscribe their networks by nearly four times their overall
capacities, the Exodus network is under-subscribed by 50%, allowing room for
unanticipated bursts in demand.  Systems are in place so that if at any time
traffic on the Exodus network exceeds 40% of its maximum volume, we add more
bandwidth to our network capacity.  By using a dual connection into and out of
every Internet Data Center, 50% of network traffic is programmed over one line,
while the other 50% travels over a separate line, leaving a large percentage of
headroom on either line to handle spikes in demand.  In the unlikely event that
one line fails, traffic is automatically re-routed to the other line.  In
addition, private exchange peering and shortest-path routing ensure customers
are always securely connected to Exodus' DS3 WAN backbone.

                                      -35-
<PAGE>

Exodus' network will grow in step with its customers' needs.  To keep up with
customer demand, Exodus will continue to peer with every ISP connecting to an
IXP.  In addition, Exodus is continuing R&D efforts to stay on top of all new
quality-of-service technologies as they become available, including Tag
Switching, IP Switching, RSVP and VPN technologies.

                                                                   -------------
                           SWITCHBOARD  INCORPORATED

                      Nonstatutory Stock Option Agreement
                    Granted Under 1999 Stock Incentive Plan


1.   Grant of Option.
     ---------------

     This agreement evidences the grant by Switchboard Incorporated, a Delaware
corporation (the "Company"), on October 13, 1999 (the "Grant Date") to Douglas
J. Greenlaw, an employee of the Company (the "Participant"), of an option to
purchase, in whole or in part, on the terms provided herein and in the Company's
1999 Stock Incentive Plan (the "Plan"), a total of 7,000 shares (the "Shares")
of common stock, $0.01 par value per share, of the Company ("Common Stock") at
$9.00 per Share. Unless earlier terminated, this option shall expire on October
13, 2009 (the "Final Exercise Date").

     It is intended that the option evidenced by this agreement shall not be an
incentive stock option as defined in Section 422 of the Internal Revenue Code of
1986, as amended and any regulations promulgated thereunder (the "Code").
Except as otherwise indicated by the context, the term "Participant", as used in
this option, shall be deemed to include any person who acquires the right to
exercise this option validly under its terms.

2.   Vesting Schedule.
     ----------------

     (a) This option will become exercisable ("vest") as to 100% of the original
number of Shares on the earlier of (a) the effective date of the initial
registration of the Company's Common Stock under the Securities Act of 1933, as
amended or (B) five (5) years from the date of grant.

     The right of exercise shall be cumulative so that to the extent the option
is not exercised in any period to the maximum extent permissible it shall
continue to be exercisable, in whole or in part, with respect to all shares for
which it is vested until the earlier of the Final Exercise Date or the
termination of this option under Section 3 hereof or the Plan.

     (b) Early Exercise Alternative.  Notwithstanding the exercisability
         --------------------------
schedule set forth in paragraph (a), the Participant may elect to exercise this
option as to the unvested Shares (in addition to the vested Shares) if
simultaneously with such exercise the Participant enters into a Stock
Restriction Agreement with the Company in the form attached hereto as Exhibit A
                                                                      ---------
(the "Stock Restriction Agreement"). The Stock Restriction Agreement provides
that the unvested Shares shall be subject to a right of repurchase (the
"Purchase Option") in favor of the Company at the $9.00 exercise price (as
adjusted pursuant to the terms hereof) in the event that the Participant ceases
to be employed by the Company.

<PAGE>

3.   Exercise of Option.
     ------------------

     (a)  Form of Exercise.  Each election to exercise this option shall be in
          ----------------
writing, signed by the Participant, and received by the Company at its principal
office, accompanied by this agreement, and payment in full in the manner
provided in the Plan.  The Participant may purchase less than the number of
shares covered hereby, provided that no partial exercise of this option may be
for any fractional share or for fewer than ten whole shares.

     (b)  Continuous Relationship with the Company Required. Except as otherwise
          -------------------------------------------------
provided in this Section 3, this option may not be exercised unless the
Participant, at the time he or she exercises this option, is, and has been at
all times since the Grant Date, an employee, officer or director of, or
consultant or advisor to, the Company or any parent or subsidiary of the Company
as defined in Section 424(e) or (f) of the Code (an "Eligible Participant").

     (c)  Termination of Relationship with the Company.  If the Participant
          --------------------------------------------
ceases to be an Eligible Participant for any reason, then, except as provided in
paragraphs (d) and (e) below, the right to exercise this option shall terminate
30 days after such cessation (but in no event after the Final Exercise Date),
provided, that, this option shall be exercisable only to the extent that the
- --------  ----
Participant was entitled to exercise this option on the date of such cessation.
Notwithstanding the foregoing, if the Participant, prior to the Final Exercise
Date, violates the non-competition or confidentiality provisions of the Plan or
any employment contract, confidentiality and nondisclosure agreement or other
agreement between the Participant and the Company, the right to exercise this
option shall terminate immediately upon such violation.

     (d)  Exercise Period Upon Death or Disability.  If the Participant dies or
          ----------------------------------------
becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to
the Final Exercise Date while he or she is an Eligible Participant and the
Company has not terminated such relationship for "cause" as specified in
paragraph (e) below, this option shall be exercisable, within the period of six
months following the date of death or disability of the Participant by the
Participant, provided, that, this option shall be exercisable only to the extent
             --------  ----
that this option was exercisable by the Participant on the date of his or her
death or disability, and further provided that this option shall not be
exercisable after the Final Exercise Date.

     (e)  Discharge for Cause.  If the Participant, prior to the Final Exercise
          -------------------
Date, is discharged by the Company for "cause" (as defined below), the right to
exercise this option shall terminate immediately upon the effective date of such
discharge.  "Cause" shall mean, with respect to any Participant who has entered
into an employment or consulting agreement with the Company, a material breach
of such agreement by the

                                       2
<PAGE>

Participant, or if such agreement provides for termination for cause, the
definition of "cause" set forth in such agreement. With respect to any other
Participant, "cause" shall mean (i) conviction or pleading guilty (including a
plea of nolo contendere) with respect to the commission of a felony, (ii) acts
of dishonesty or moral turpitude which are materially detrimental to the Company
and/or its affiliates as determined in good faith by the Board, (iii) failure of
the Participant to obey the reasonable and lawful orders of the Board or the
chief executive officer of the Company after written demand that the Participant
do so, (iv) gross negligence by the Participant in the performance of, or wilful
disregard by the Participant of, the Participant's obligations to the Company,
or (v) the breach by the Participant of any of the Participant's obligations of
confidentiality with respect to the Company. The Participant shall be considered
to have been discharged for "cause" if the Company determines, within 30 days
after the Participant's resignation, that discharge for cause was warranted.

4.   Proxy.  The Participant hereby appoints Banyan Worldwide, a Massachusetts
     -----
corporation, and/or its designee(s) ("Banyan"), as the Participant's attorney-
in-fact and proxy, with full power of substitution, for and in the Participant's
name, to vote, express consent or disapproval, or otherwise act in such manner
(including pursuant to written consent) and upon such matters as Banyan or its
designee(s), proxy or substitute(s) shall, in its or their sole discretion, deem
proper with respect to any and all of the shares issued upon any exercise of
this option or issued in respect to such shares as a stock dividend, stock split
or otherwise (collectively, for purposes of Sections 4, 5 and 6 hereof, the
"Option Shares").  The proxy granted hereby shall be irrevocable and may be
exercised at any meeting or in respect of any written consent of stockholders.
This proxy is coupled with an interest sufficient in law to support such proxy.
This proxy shall remain in full force and effect and be enforceable against any
donee, transferee or assignee of the stock.  In addition to any other applicable
limitations pursuant to the terms of this option, the Participant agrees not to
sell, assign, transfer, loan, tender, pledge, hypothecate, exchange, encumber or
otherwise dispose of, or issue an option or call with respect to, any of the
Option Shares, or impair such Option Shares, in each case unless, and as a
condition precedent thereto, the transferee of such Option Shares executes and
delivers to Banyan an agreement to be bound by the terms of this Section 4.  Any
purported transfer in violation of this Section 4 shall be null and void and
shall not be recognized by the Company or reflected on the stock records of the
Company.  The Participant shall cause the Company to require any certificates
representing any and all Option Shares issued upon any exercise of this option
to bear a legend referencing the restrictions on transfer set for in this
Section 4, which legend shall be subject to the approval of Banyan.
Notwithstanding anything to the contrary in the foregoing, the provisions of,
including, without limitation, the proxy appointed by, this Section 4 shall
terminate upon the closing of the Company's initial public offering,
underwritten by a nationally recognized underwriter, pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the
"Securities

                                       3
<PAGE>

Act").

5.   Repurchase of Option Shares Upon Termination of Employment.  The following
     ----------------------------------------------------------
repurchase provisions shall apply to any and all Option Shares;

     (a)  Repurchase Rights.  If the Participant for any reason whatsoever
          -----------------
(including without limitation death, disability, or voluntary or involuntary
termination) ceases to be employed by the Company prior to the date specified in
Section 5(d) below for the expiration of these restrictions, then during the 90-
day period following such termination the Company may elect, by written notice
delivered to the Participant, to repurchase all or any portion of the Option
Shares, at a price per share equal to the fair market value of such Option
Shares as of the close of business on the date of termination of the
Participant's employment.  Such fair market value shall be determined by mutual
agreement of the Company and the Participant.  Failing such agreement between
the Participant and the Company within 30 days of the date of the Company's
notice electing to repurchase such Option Shares, the fair market value of such
Option Shares shall be determined by three appraisers, one designated within
five days after the termination of said 30-day period by the Participant or his
or her legal representatives (which appraiser shall not be the Participant or
his or her legal representative), one within said period of five days by the
Company (which appraiser shall not be an officer, director or employee of the
Company) and the third within five days after said appointment last occurring by
the two appraisers so chosen.  Successor appraisers, if any shall be required,
shall be appointed, within a reasonable time, as nearly as may be in the manner
provided as to the related original appointment.  No appointment shall be deemed
as having been accomplished unless such appraiser shall have accepted in writing
his appointment as such within the time limited for his appointment.  Notice of
each appointment of an appraiser shall be given promptly to the other parties in
interest.  Any expenses relating to the appointment and service of an appraiser
shall be paid by the party appointing such appraiser or, in the case of the
appraiser appointed by the appraisers chosen by the Company and the Participant,
shall be paid by the Company.  Said appraisers shall proceed promptly to
determine the fair market value of said Share or Option Shares by agreement of
any two of the appraisers, which shall be conclusive upon all parties in
interest in such Option Shares.  Promptly following such determination, the
appraisers shall mail or deliver such notice of such determination to the
Participant and the Company.

     (b)  Repurchase Procedure.  Upon notice from the Company of exercise of its
          --------------------
rights under this Section 5 and determination of the purchase price for the
Option Shares so repurchased, the Participant shall transfer the Option Shares
or appropriate part thereof to the Company against payment by the Company of the
purchase price therefor.  If upon the expiration of the 90-day period following
the Participant's termination of employment the Company shall have failed to
elect to repurchase all of

                                       4
<PAGE>

the Option Shares, the repurchase rights with respect to the Option Shares not
so elected to be repurchased imposed by this Section 5 shall terminate, and the
Participant or his or her legal representatives may thereafter transfer such
Option Shares. The Participant or his or her legal representatives may in no
event transfer any Option Shares prior thereto, other than to the Company.

     (c)  Failure of Participant to Comply.  If the Participant fails to comply
          --------------------------------
with any of the provisions of this Section 5, the Company, at its option and in
addition to its other remedies, may suspend the rights of the Participant to
vote and to receive dividends on the Option Shares, or may refuse to register on
its books any transfer or change in the ownership of the Option Shares or in the
right to vote thereon, until the provisions of this Section 5 are complied with
to the satisfaction of the Company.

     (d)  Expiration.  The restriction contained in this Section 5 shall expire
          ----------
upon the closing of the Company's initial public offering, underwritten by a
nationally recognized underwriter, pursuant to an effective registration
statement under the Securities Act (such expiration date shall be referred to
herein as the "Expiration Date").

     (e)  Safekeeping. The Participant acknowledges that the Company may, in its
          -----------
discretion, retain for safekeeping stock certificates representing all Option
Shares purchased hereunder by the Participant.  The Participant further
acknowledges that the Company may, to insure that the Participant complies with
the restriction of this Section 5, continue to retain such stock certificates
until the earlier of the Expiration Date or the date of expiration of these
repurchase rights under Section 5(b) above.  At the time of any exercise of this
option, in whole or in part, the Participant shall execute such further
agreement as the Company may require to implement the foregoing.

6.   Right of First Refusal.
     ----------------------

     (a)  General.  The Participant shall not sell, assign, pledge, or in any
          -------
manner transfer any of the Option Shares or any right or interest therein,
whether voluntarily or by operation of law, or by gift or otherwise, except by a
transfer which meets the requirements of the provisions of this Section 6.

     (b)  Restrictions on Transfer.  If at any time or from time to time the
          ------------------------
Participant intends to sell or transfer any Option Shares to a third party, the
Participant shall provide notice thereof to the Company prior to such transfer
(which in the case of a sale shall include a bona fide purchase agreement with a
viable purchaser).  The Company shall have an option for 30 days following the
date of receipt of the Participant's notice to purchase such Option Shares on
the terms upon which the Option Shares were to be purchased by or transferred to
the third party by the Participant.  If the Company does not exercise its right
of first refusal under this Section

                                       5
<PAGE>

6(b) with respect to such proposed sale or transfer within such 30-day period,
the Participant shall be free to sell or transfer such Option Shares to the
third party identified in the Participant's notice for a period of 45 days after
the expiration of the 30-day period following the date of receipt of the
Participant's notice. Such sale or transfer must be on terms no more favorable
to the recipient than those set forth in the Participant's notice. In no event

                           SWITCHBOARD INCORPORATED

                      NONSTATUTORY STOCK OPTION AGREEMENT

     1.   Grant of Option.    Switchboard Incorporated, a Delaware Corporation
          ----------------
(the "Company"), hereby grants to Douglas J. Greenlaw (the "Optionee"), an
option, pursuant to the Company's 1996 Stock Incentive Plan (the "Plan"), to
purchase an aggregate of 893,000 shares of Common Stock, $.01 par value per
share, of the Company ("Common Stock"), at a price of $9.00 per share,
purchasable as set forth and subject to the terms and conditions of this option
and the Plan.  The date of grant of this option is October 13, 1999.  Except

replaced from time to time (the "Code").

     2.   Non-Statutory Stock Option.  This option is not intended to qualify as
          ---------------------------
an incentive stock option ("Incentive Stock Option") within the meaning of
Section 422 of the Code.

     3.  Exercise of Option and Provisions for Termination.
         -------------------------------------------------

          (a)  Vesting Schedule.  Except as otherwise provided in this
               -----------------
Agreement, this option may be exercised prior to the tenth anniversary of the
date of grant (hereinafter the "Final Exercise Date") in installments as to not
more than the number of shares set forth in the table below during the
respective installment periods set forth below.

               (i)   Ninety-three thousand (93,000) shares will vest on the
                     earlier of (A) the effective date of the initial
                     registration of the Company's Common Stock under the
                     Securities Act of 1933, as amended or (B) five (5) years
                     from the date of grant;

               (ii)  Two hundred thousand (200,000) shares will vest on the
                     earlier of (A) the date that the Company's Market
                     Capitalization equals or exceeds two billion dollars for a
                     period of one-hundred and eighty (180) consecutive calendar
                     days or (B) five (5) years from the date of grant

               (iii) One hundred fifty thousand (150,000) shares will vest on
                     the earlier of (A) the date that the Company's Market
                     Capitalization equals or exceeds one and a half billion
                     dollars for a period of ninety (90) consecutive calendar
                     days or (B) four (4) years from the date of grant;

               (iv)  One hundred fifty thousand (150,000) shares will vest on

                     period of ninety (90) consecutive calendar days or (B)

<PAGE>

The right of exercise shall be cumulative so that if the option is not exercised
to the maximum extent permissible during any exercise period, it shall be
exercisable, in whole or in part, with respect to all shares not so purchased at
any time prior to the Final Exercise Date or the earlier termination of this
option.  This option may not be exercised at any time on or after the Final
Exercise Date.

     For the purposes of this provision 3(a), "Market Capitalization" means the
number of outstanding shares of Common Stock of the Company multiplied by the
"fair market value" of a share of Common Stock as of a particular date (the
"Determination Date"). The "fair market value" shall mean: (i) if shares of
Common Stock are traded on a national securities exchange (an "Exchange"), the
average of the closing prices of a share of the Common Stock of the Company on
the last twenty (20) trading days prior to the Determination Date reported on
such Exchange as reported in The Wall Street Journal or comparable reporting
service; or (ii) if shares of Common Stock are not traded on an Exchange but
trade in the over-the-counter market and such shares are quoted on the Nasdaq
National Market System or the Nasdaq Small-Cap Market (either, "NASDAQ"), (A)
the average of the last sale prices reported on NASDAQ or (B) if such shares are
an issue for which last sale prices are not reported on NASDAQ, the average of
the closing bid and ask prices, in each case on the last twenty (20) trading
days (or if the relevant price or quotation did not exist on any of such days,
the relevant price or quotation on the next preceding business day on which
there was such a price or quotation) prior to the Determination Date as reported
in The Wall Street Journal or comparable reporting service; or (iii) if no price
can be determined on the basis of the above methods of valuation, then the
judgment of valuation shall be determined in good faith by the Board of
Directors of the Company, which determination shall be described in a duly
adopted board resolution certified by the Company's Clerk or Assistant Clerk.

          (b)  Exercise Procedure.  Subject to the conditions set forth in this
               ------------------
Agreement, this option shall be exercised by the Optionee's delivery of written
notice of exercise to the Treasurer of the Company, specifying the number of
shares to be purchased and the purchase price to be paid therefor and
accompanied by payment in full in accordance with Section 4.  Such exercise
shall be effective upon receipt by the Treasurer of the Company of such written
notice together with the required payment.  The Optionee may purchase less than
the number of shares covered hereby, provided that no partial exercise of this
option may be for any fractional share or for fewer than ten whole shares.

          (c)  Continuous Employment Required.  This option may not be exercised
               ------------------------------
unless the Optionee, at the time he or she exercises this option, is, and has
been at all times since the date of grant of this option, an employee of the
Company.  For all purposes of this option, (i) "employment" shall be defined in
accordance with the provisions of Section 1.421-7(h) of the Income Tax
Regulations or any successor regulations, and (ii) if this option shall be
assumed or a new option substituted therefor in a transaction to which Section
424(a) of the Code applies, employment by such assuming or substituting
corporation (hereinafter called the "Successor Corporation") shall be considered
for all purposes of this option to be employment by the Company.

          (d)  Termination of Employment.  If the Optionee ceases to be employed
               -------------------------
by the Company for any reason (including without limitation death, disability,
or voluntary or involuntary termination), then the right to exercise this option
shall terminate immediately upon such cessation.

          (e) Early Exercise Alternative.  Notwithstanding the exercisability
              --------------------------
schedule set forth in paragraph (a), the Optionee may elect to exercise this
option as to the unvested shares (in addition to the vested shares) if
simultaneously with such exercise the Optionee enters into a Stock
Restriction Agreement with the Company in the form attached hereto as Exhibit A
                                                                      ---------
(the "Stock Restriction Agreement"). The Stock Restriction Agreement provides
that the unvested shares shall be subject to a right of repurchase (the
"Purchase Option") in favor of the Company at the $9.00 exercise price (as
adjusted pursuant to the terms hereof) in the event that the Optionee ceases to
be employed by the Company.

     4.   Payment of Purchase Price.
          -------------------------

          (a)  Method of Payment.  Payment of the purchase price for shares
               -----------------
purchased upon exercise of this option shall be made by delivery of cash or a
check in an amount equal to the exercise price of such option or, with the prior
consent of the Company (which may be withheld in its sole discretion), by (A)
delivery of shares of Common Stock owned by the Optionee for at least six
months,

                                      -2-
<PAGE>

valued at their fair market value, as determined in (b) below, (B) delivery of a
promissory note of the Optionee to the Company on terms determined by the Board,
(C) delivery of an irrevocable undertaking by a broker to deliver promptly to
the Company sufficient funds to pay the exercise price or delivery of
irrevocable instructions to a broker to deliver promptly to the Company cash or
a check sufficient to pay the exercise price, (D) payment of such other lawful
consideration as the Board may determine, or (E) any combination of the
foregoing.

          (b)  Valuation of Shares or Other Non-Cash Consideration Tendered in
               ---------------------------------------------------------------
Payment of Purchase Price.  For the purposes hereof, the fair market value of
- -------------------------
any share of the Company's Common Stock or other non-cash consideration which
may be delivered to the Company in exercise of this option shall be determined
in good faith by the Board of Directors of the Company.

          (c)  Delivery of Shares Tendered in Payment of Purchase Price.  If the
               --------------------------------------------------------
Optionee exercises this option by delivery of shares of Common Stock of the
Company, the certificate or certificates representing the shares of Common Stock
of the Company to be delivered shall be duly executed in blank by the Optionee
or shall be accompanied by a stock power duly executed in blank suitable for
purposes of transferring such shares to the Company.  Fractional shares of
Common Stock of the Company will not be accepted in payment of the purchase
price of shares acquired upon exercise of this option.

          (d)  Restrictions on Use of Option Stock.  Notwithstanding the
               -----------------------------------
foregoing, no shares of Common Stock of the Company may be tendered in payment
of the purchase price of shares purchased upon exercise of this option if the
shares to be so tendered were acquired within six (6) months before the date of
such tender, through the exercise of an option granted under the Plan or any
other stock option or restricted stock plan of the Company.

     5.   Delivery of Shares; Compliance With Securities Laws, Etc.
          --------------------------------------------------------

          (a)  General.  The Company shall, upon payment of the option price for
               -------
the number of shares purchased and paid for, make prompt delivery of such shares
to the Optionee, provided that if any law or regulation requires the Company to
                 -------- ----
take any action with respect to such shares before the issuance thereof, then
the date of delivery of such shares shall be extended for the period necessary
to complete such action.

          (b)  Compliance With Securities Laws, Etc.  The Company will not be
               -------------------------------------
obligated to deliver any shares of Common Stock pursuant to the Plan or to
remove restriction from shares previously delivered under the Plan (i) until all
conditions of the option have been satisfied or removed, (ii) until, in the
opinion of the Company's counsel, all applicable federal and state laws and
regulation have been complied with, (iii) if the outstanding Stock is at the
time listed on any stock exchange, until the shares to be delivered have been
listed or authorized to be listed on such exchange upon official notice of
issuance, and (iv) until all other legal matters in connection with the issuance
and delivery of such shares have been approved by the Company's counsel.

     6.   Nontransferability of Option.  This option is personal and no rights
          ----------------------------
granted hereunder may be transferred, assigned, pledged or hypothecated in any
way (whether by operation of law or otherwise) nor shall any such rights be
subject to execution, attachment or similar process.  Upon any attempt to
transfer, assign, pledge, hypothecate or otherwise dispose of this option or of
such rights contrary to the provisions hereof, or upon the levy of any
attachment or similar process upon this option or such rights, this option and
such rights shall, at the election of the Company, become null and void.

                                      -3-
<PAGE>

     7.   Proxy.  The Optionee hereby appoints Banyan Worldwide, a Massachusetts
          -----
corporation, and/or its designee(s) ("Banyan"), as the Optionee's attorney-in-
fact and proxy, with full power of substitution, for and in the Optionee's name,
to vote, express consent or disapproval, or otherwise act in such manner
(including pursuant to written consent) and upon such matters as Banyan or its
designee(s), proxy or substitute(s) shall, in its or their sole discretion, deem
proper with respect to any and all of the shares issued upon any exercise of
this option or issued in respect to such shares as a stock dividend, stock split
or otherwise (collectively, for purposes of Sections 7, 8 and 9 hereof, the
"Shares").  The proxy granted hereby shall be irrevocable and may be exercised
at any meeting or in respect of any written consent of stockholders.  This proxy
is coupled with an interest sufficient in law to support such proxy.  This proxy
shall remain in full force and effect and be enforceable against any donee,
transferee or assignee of the stock.  In addition to any other applicable
limitations pursuant to the terms of this option, the Optionee agrees not to
sell, assign, transfer, loan, tender, pledge, hypothecate, exchange, encumber or
otherwise dispose of, or issue an option or call with respect to, any of the
Shares, or impair such Shares, in each case unless, and as a condition precedent
thereto, the transferee of such Shares executes and delivers to Banyan an
agreement to be bound by the terms of this Section 7.  Any purported transfer in
violation of this Section 7 shall be null and void and shall not be recognized
by the Company or reflected on the stock records of the Company.  The Optionee
shall cause the Company to require any certificates representing any and all
Shares issued upon any exercise of this option to bear a legend referencing the
restrictions on transfer set for in this Section 7, which legend shall be
subject to the approval of Banyan.  Notwithstanding anything to the contrary in
the foregoing, the provisions of, including, without limitation, the proxy
appointed by, this Section 7 shall terminate upon the closing of the Company's
initial public offering, underwritten by a nationally recognized underwriter,
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "Securities Act").

     8.   Repurchase of Shares Upon Termination of Employment.  The following
          ---------------------------------------------------
repurchase provisions shall apply to any and all Shares;

          (a)  Repurchase Rights.  If the Optionee for any reason whatsoever
               -----------------
(including without limitation death, disability, or voluntary or involuntary
termination) ceases to be employed by the Company prior to the date specified in
Section 8(d) below for the expiration of these restrictions, then during the 90-
day period following such termination the Company may elect, by written notice
delivered to the Optionee, to repurchase all or any portion of the Shares, at a
price per share equal to the fair market value of such Shares as of the close of
business on the date of termination of the Optionee's employment.  Such fair
market value shall be determined by mutual agreement of the Company and the
Optionee.  Failing such agreement between the Optionee and the Company within 30
days of the date of the Company's notice electing to repurchase such Shares, the
fair market value of such Shares shall be determined by three appraisers, one
designated within five days after the termination of said 30-day period by the
Optionee or his or her legal representatives (which appraiser shall not be the
Optionee or his or her legal representative), one within said period of five
days by the Company (which appraiser shall not be an officer, director or
employee of the Company) and the third within five days after said appointment
last occurring by the two appraisers so chosen.  Successor appraisers, if any
shall be required, shall be appointed, within a reasonable time, as nearly as
may be in the manner provided as to the related original appointment.  No
appointment shall be deemed as having been accomplished unless such appraiser
shall have accepted in writing his appointment as such within the time limited
for his appointment.  Notice of each appointment of an appraiser shall be given
promptly to the other parties in interest.  Any expenses relating to the
appointment and service of an appraiser shall be paid by the party appointing
such appraiser or, in the case of the appraiser appointed by the appraisers
chosen by the Company and the Optionee, shall be paid by the Company.  Said
appraisers shall proceed promptly to determine the fair market value of said
Share or Shares by agreement of any two of the appraisers, which

                                      -4-
<PAGE>

shall be conclusive upon all parties in interest in such Shares. Promptly
following such determination, the appraisers shall mail or deliver such notice
of such determination to the Optionee and the Company.

          (b)  Repurchase Procedure. Upon notice from the Company of exercise of
               --------------------
its rights under this Section 8 and determination of the purchase price for the
Shares so repurchased, the Optionee shall transfer the Shares or appropriate
part thereof to the Company against payment by the Company of the purchase price
therefor.  If upon the expiration of the 90-day period following the Optionee's
termination of employment the Company shall have failed to elect to repurchase
all of the Shares, the repurchase rights with respect to the Shares not so
elected to be repurchased imposed by this Section 8 shall terminate, and the
Optionee or his or her legal representatives may thereafter transfer such
Shares.  The Optionee or his or her legal representatives may in no event
transfer any Shares prior thereto, other than to the Company.

          (c)  Failure of Optionee to Comply.  If the Optionee fails to comply
               -----------------------------
with any of the provisions of this Section 8, the Company, at its option and in
addition to its other remedies, may suspend the rights of the Optionee to vote
and to receive dividends on the Shares, or may refuse to register on its books
any transfer or change in the ownership of the Shares or in the right to vote
thereon, until the provisions of this Section 8 are complied with to the
satisfaction of the Company.

          (d)  Expiration.  The restriction contained in this Section 8 shall
               ----------
expire upon the closing of the Company's initial public offering, underwritten
by a nationally recognized underwriter, pursuant to an effective registration
statement under the Securities Act of 1933, as amended (the "Securities Act")
(such expiration date shall be referred to herein as the "Expiration Date").

          (e)  Safekeeping.  The Optionee acknowledges that the Company may, in
               -----------
its discretion, retain for safekeeping stock certificates representing all
Shares purchased hereunder by the Optionee.  The Optionee further acknowledges
that the Company may, to insure that the Optionee complies with the restriction
of this Section 8, continue to retain such stock certificates until the earlier
of the Expiration Date or the date of expiration of these repurchase rights
under Section 8(b) above.  At the time of any exercise of this option, in whole
or in part, the Optionee shall execute such further agreement as the Company may
require to implement the foregoing.

     9.   Right of First Refusal.
          ----------------------

          (a)  General.  The Optionee shall not sell, assign, pledge, or in any
               -------
manner transfer any of the Shares or any right or interest therein, whether
voluntarily or by operation of law, or by gift or otherwise, except by a
transfer which meets the requirements of the provisions of this Section 9.

          (b)  Restrictions on Transfer. If at any time or from time to time the
               ------------------------
Optionee intends to sell or transfer any Shares to a third party, the Optionee
shall provide notice thereof to the Company prior to such transfer (which in the
case of a sale shall include a bona fide purchase agreement with a viable
purchaser).  The Company shall have an option for 30 days following the date of
receipt of the Optionee's notice to purchase such Shares on the terms upon which
the Shares were to be purchased by or transferred to the third party by the
Optionee.  If the Company does not exercise its right of first refusal under
this Section 9(b) with respect to such proposed sale or transfer within such 30-
day period, the Optionee shall be free to sell or transfer such Shares to the
third party identified in the Optionee's notice for a period of 45 days after
the expiration of the 30-day period following the date of receipt of the
Optionee's notice.  Such sale or transfer must be on terms no more favorable to
the recipient than those set forth in the Optionee's notice.  In no event may
Shares be sold or transferred to any then-current

                                      -5-
<PAGE>

competitor of the Company. Any transfer or sale of Shares by the Optionee will
be conditional upon the recipient acknowledging in writing the option set forth
in this Section 9(b) and the other restrictions to which the Shares are subject.

          (c)  Failure of Optionee to Comply.  If the Optionee's notice in
               -----------------------------
respect of any Shares is not received by the Company as provided in Section 9(b)
above, or if the Optionee fails to comply with the provisions of Section 9(b)
above in respect of any such Shares in any other regard, the Company, at its
option and in addition to its other remedies, may suspend the rights to vote or
to receive dividends on said Shares, or may refuse to register on its books any
transfer or change in ownership of said Shares or in the right to vote thereon,
until the provisions of Section 9(b) are complied with to the satisfaction of
the Company; and if the required Optionee's notice is not received by the
Company after written demand by the Company, the Company may also independently
proceed as though a proper Optionee's notice has been received at the expiration
of ten days after mailing such demand, and, if the Company exercises its rights
under Section 9(b) with respect to said Shares or any of them, the Shares

          (b)  Board Authority to Make Adjustments.  Any adjustments under this
               -----------------------------------

binding and conclusive.  No fractional shares will be issued pursuant to this
option on account of any such adjustments.

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

          (a)  Representations.  The Optionee represents, warrants and covenants
               ---------------
that:

               (i)   Any shares purchased upon exercise of this option shall be
               acquired for the Optionee's account for investment only and not
               with a view to, or for sale in connection with, any distribution
               of the shares in violation of the Securities Act or any rule or
               regulation under the Securities Act.

               (ii)  The Optionee has had such opportunity as he or she has
               deemed adequate to obtain from representatives of the Company
               such information as is necessary to permit the Optionee to
               evaluate the merits and risks of his or her investment in the
               Company.

               (iii) The Optionee is able to bear the economic risk of holding
               shares acquired pursuant to the exercise of this option for an
               indefinite period.

               (iv)  The Optionee understands that (A) the shares acquired
               pursuant to the exercise of this option will not be registered
               under the Securities Act and are "restricted securities" within
               the meaning of Rule 144 under the Securities Act; (B) such shares
               cannot be sold, transferred or otherwise disposed of unless they
               are subsequently registered under the Securities Act or an
               exemption from registration is then available; (C) in any event,
               an exemption from registration under Rule 144 or otherwise under
               the Securities Act may not be available for at least two years
               and even then will not be available unless a public market then
               exists for the Common Stock, adequate information concerning the
               Company is then available to the public and other terms and
               conditions of Rule 144 are complied with; and (D) there is now no
               registration statement on file with the Securities and Exchange
               Commission with respect to any stock of the Company and the
               Company has no obligation or current intention to register any
               shares acquired pursuant to the exercise of this option under the
               Securities Act.

               (v)   The Optionee agrees that, if the Company offers for the
               first time any of its Common Stock for sale pursuant to a
               registration statement under the Securities Act, the Optionee
               will not, without the prior written consent of the Company,
               publicly offer, sell, contract to sell or otherwise dispose of,
               directly or indirectly, any shares purchased upon exercise of
               this option for a period of 180 days after the effective date of
               such registration statement.

                                      -7-
<PAGE>

By making payment upon exercise of this option, the Optionee shall be deemed to
have reaffirmed, as of the date of such payment, the representations made in
this Section 14.

          (b)  Legends on Stock Certificates.  All stock certificates
               -----------------------------
representing shares of Common Stock issued to the Optionee upon exercise of this
option shall have affixed thereto legends substantially in the following forms,
in addition to any other legends required by applicable state law:


          "The shares of stock represented by this certificate have not been
          registered under the Securities Act of 1933 and may not be
          transferred, sold or otherwise disposed of in the absence of an
          effective registration statement with respect to the shares evidenced
          by this certificate, filed and made effective under the Securities Act
          of 1933, or an opinion of counsel satisfactory to the Company to the
          effect that registration under such Act is not required."

          "The shares of stock represented by this certificate are subject to
          certain restrictions on transfer and repurchase rights contained in an
          Option Agreement, a copy of which will be furnished upon request by
          the issuer."

To ensure compliance with the terms of this agreement, the Company may issue to
its transfer agent appropriate stop transfer instructions with respect to the
Shares.

     15.  Miscellaneous.
          -------------

          (a)  The Board may amend, modify or terminate any outstanding option,
including substituting therefor another option of the same or a different type,
changing the date of exercise or realization, provided that the Optionee's
consent to such action shall be required unless the Board determines that the
action, taking into account any related action, would not materially and
adversely affect the Optionee.  The Board may at any time accelerate the time at
which all or any part of an Option may be exercised.

          (b)  All notices under this option shall be mailed or delivered by
hand to the parties at their respective addresses set forth beneath their names
below or at such other address as may be designated in writing by either of the
parties to one another.

          (c)  This option shall be governed by and construed in accordance with
the laws of the State of Delaware.

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

                           SWITCHBOARD INCORPORATED

                       INCENTIVE STOCK OPTION AGREEMENT


     1.   Grant of Option.    Switchboard Incorporated, a Delaware Corporation
          ----------------
(the "Company"), hereby grants to Dean Polnerow (the "Optionee"), an option,
pursuant to the Company's 1996 Stock Incentive Plan (the "Plan"), to purchase an
aggregate of 145,000 shares of Common Stock, $.01 par value per share, of the

and future subsidiaries of the Company as defined in Sections 424(e) and 424(f)
of the Internal Revenue Code of 1986, as amended or replaced from time to time
(the "Code").

     2.   Incentive Stock Option.  To the extent permitted by applicable law,
          -----------------------
this option is intended to qualify as an incentive stock option ("Incentive
Stock Option") within the meaning of Section 422 of the Code.

     3.   Exercise of Option and Provisions for Termination.
          -------------------------------------------------

          (a)  Vesting Schedule.  Except as otherwise provided in this
               -----------------
Agreement, this option may be exercised prior to the tenth anniversary of the
date of grant (hereinafter the "Final Exercise Date") in installments as to not
more than the number of shares set forth in the table below during the
respective installment periods set forth below.

               (i)   Twenty-five thousand (25,000) shares will vest on the
                     earlier of (A) the effective date of the initial
                     registration of the Company's Common Stock under the
                     Securities Act of 1933, as amended or (B) five (5) years
                     from the date of grant;

               (ii)  Fifty thousand (50,000) shares will vest on the earlier of
                     (A) the date that the Company's Market Capitalization
                     equals or exceeds two billion dollars for a period of one-
                     hundred and eighty (180) consecutive calendar days or (B)
                     four (4) years from the date of grant;

               (iii) Thirty-five thousand (35,000) shares will vest on the
                     earlier of (A) the date that the Company's Market
                     Capitalization equals or exceeds one and a half billion
                     dollars for a period of ninety (90) consecutive calendar
                     days or (B) three (3) years from the date of grant;

               (iv)  Thirty-five thousand (35,000) shares will vest on the
                     earlier of (A) the date that the Company's Market
                     Capitalization equals or exceeds one billion dollars for a
                     period of ninety (90) consecutive calendar days or (B) two
                     (2) years from the date of grant.

The right of exercise shall be cumulative so that if the option is not exercised
to the maximum extent permissible during any exercise period, it shall be
exercisable, in whole or in part, with respect to all shares not so purchased at
any time prior to the Final Exercise Date or the earlier termination of this
option.  This option may not be exercised at any time on or after the Final
Exercise Date.
<PAGE>

     For the purposes of this provision 3(a), "Market Capitalization" means the
number of outstanding shares of Common Stock of the Company multiplied by the
"fair market value" of a share of Common Stock as of a particular date (the
"Determination Date").  The "fair market value" shall mean:  (i) if shares of
Common Stock are traded on a national securities exchange (an "Exchange"), the
average of the closing prices of a share of the Common Stock of the Company on
the last twenty (20) trading days prior to the Determination Date reported on
such Exchange as reported in The Wall Street Journal or comparable reporting
service; or (ii) if shares of Common Stock are not traded on an Exchange but
trade in the over-the-counter market and such shares are quoted on the Nasdaq
National Market System or the Nasdaq Small-Cap Market (either, "NASDAQ"), (A)
the average of the last sale prices reported on NASDAQ or (B) if such shares are
an issue for which last sale prices are not reported on NASDAQ, the average of
the closing bid and ask prices, in each case on the last twenty (20) trading
days (or if the relevant price or quotation did not exist on any of such days,
the relevant price or quotation on the next preceding business day on which
there was such a price or quotation) prior to the Determination Date as reported
in The Wall Street Journal or comparable reporting service; or (iii) if no price
can be determined on the basis of the above methods of valuation, then the
judgment of valuation shall be determined in good faith by the Board of
Directors of the Company, which determination shall be described in a duly
adopted board resolution certified by the Company's Clerk or Assistant Clerk.

          (b)  Exercise Procedure.  Subject to the conditions set forth in this
               ------------------
Agreement, this option shall be exercised by the Optionee's delivery of written
notice of exercise to the Treasurer of the Company, specifying the number of
shares to be purchased and the purchase price to be paid therefor and
accompanied by payment in full in accordance with Section 4.  Such exercise
shall be effective upon receipt by the Treasurer of the Company of such written
notice together with the required payment.  The Optionee may purchase less than
the number of shares covered hereby, provided that no partial exercise of this
option may be for any fractional share or for fewer than ten whole shares.

          (c)  Continuous Employment Required.  This option may not be exercised
               ------------------------------
unless the Optionee, at the time he or she exercises this option, is, and has
been at all times since the date of grant of this option, an employee of the
Company.  For all purposes of this option, (i) "employment" shall be defined in
accordance with the provisions of Section 1.421-7(h) of the Income Tax
Regulations or any successor regulations, and (ii) if this option shall be
assumed or a new option substituted therefor in a transaction to which Section
424(a) of the Code applies, employment by such assuming or substituting
corporation (hereinafter called the "Successor Corporation") shall be considered
for all purposes of this option to be employment by the Company.

          (d)  Termination of Employment.  If the Optionee ceases to be employed
               -------------------------
by the Company for any reason (including without limitation death, disability,
or voluntary or involuntary termination), then the right to exercise this option
shall terminate 90 days after such cessation (but in no event after the Final
Exercise Date, provided, that, this option shall be exercisable only to the
               --------  ----
extent that the Optionee was entitled to exercise this option on the date of
such cessation.

          (e) Early Exercise Alternative.  Notwithstanding the exercisability
              --------------------------
schedule set forth in paragraph (a), the Optionee may elect to exercise this
option as to the unvested shares (in addition to the vested shares) if
simultaneously with such exercise the Optionee enters into a Stock
Restriction Agreement with the Company in the form attached hereto as Exhibit A
                                                                      ---------
(the "Stock Restriction Agreement"). The Stock Restriction Agreement provides
that the unvested shares shall be subject to a right of repurchase (the
"Purchase Option") in favor of the Company at the $9.00 exercise price (as
adjusted pursuant to the terms hereof) in the event that the Optionee ceases to
be employed by the Company.

     4.   Payment of Purchase Price.
          -------------------------

          (a)  Method of Payment.  Payment of the purchase price for shares
               -----------------
purchased upon exercise of this option shall be made by delivery of cash or a
check in an amount equal to the exercise price of such option or, with the prior
consent of the Company (which may be withheld in its sole discretion), by (A)
delivery of shares of Common Stock owned by the Optionee for at least six
months, valued at their fair market value, as determined in (b) below, (B)
delivery of a promissory note of the Optionee to the Company on terms determined
by the Board, (C) delivery of an irrevocable undertaking by a broker to deliver
promptly to the Company sufficient funds to pay the exercise price or delivery
of

                                      -2-
<PAGE>

irrevocable instructions to a broker to deliver promptly to the Company cash or
a check sufficient to pay the exercise price, (D) payment of such other lawful
consideration as the Board may determine, or (E) any combination of the
foregoing.

          (b)  Valuation of Shares or Other Non-Cash Consideration Tendered in
               ---------------------------------------------------------------
Payment of Purchase Price.  For the purposes hereof, the fair market value of
- -------------------------
any share of the Company's Common Stock or other non-cash consideration which
may be delivered to the Company in exercise of this option shall be determined
in good faith by the Board of Directors of the Company.

          (c)  Delivery of Shares Tendered in Payment of Purchase Price.  If the
               --------------------------------------------------------
Optionee exercises this option by delivery of shares of Common Stock of the
Company, the certificate or certificates representing the shares of Common Stock
of the Company to be delivered shall be duly executed in blank by the Optionee
or shall be accompanied by a stock power duly executed in blank suitable for
purposes of transferring such shares to the Company.  Fractional shares of
Common Stock of the Company will not be accepted in payment of the purchase
price of shares acquired upon exercise of this option.

          (d)  Restrictions on Use of Option Stock.  Notwithstanding the
               -----------------------------------
foregoing, no shares of Common Stock of the Company may be tendered in payment
of the purchase price of shares purchased upon exercise of this option if the
shares to be so tendered were acquired within six (6) months before the date of
such tender, through the exercise of an option granted under the Plan or any
other stock option or restricted stock plan of the Company.

     5.   Delivery of Shares; Compliance With Securities Laws, Etc.
          --------------------------------------------------------

          (a)  General.  The Company shall, upon payment of the option price for
               -------
the number of shares purchased and paid for, make prompt delivery of such shares
to the Optionee, provided that if any law or regulation requires the Company to
                 -------- ----
take any action with respect to such shares before the issuance thereof, then
the date of delivery of such shares shall be extended for the period necessary
to complete such action.

          (b)  Compliance With Securities Laws, Etc.  The Company will not be
               -------------------------------------
obligated to deliver any shares of Common Stock pursuant to the Plan or to
remove restriction from shares previously delivered under the Plan (i) until all
conditions of the option have been satisfied or removed, (ii) until, in the
opinion of the Company's counsel, all applicable federal and state laws and
regulation have been complied with, (iii) if the outstanding Stock is at the
time listed on any stock exchange, until the shares to be delivered have been
listed or authorized to be listed on such exchange upon official notice of
issuance, and (iv) until all other legal matters in connection with the issuance
and delivery of such shares have been approved by the Company's counsel.

     6.   Nontransferability of Option.  This option is personal and no rights
          ----------------------------
granted hereunder may be transferred, assigned, pledged or hypothecated in any
way (whether by operation of law or otherwise) nor shall any such rights be
subject to execution, attachment or similar process.  Upon any attempt to
transfer, assign, pledge, hypothecate or otherwise dispose of this option or of
such rights contrary to the provisions hereof, or upon the levy of any
attachment or similar process upon this option or such rights, this option and
such rights shall, at the election of the Company, become null and void.

     7.   Proxy.  The Optionee hereby appoints Banyan Worldwide, a Massachusetts
           -----
corporation, and/or its designee(s) ("Banyan"), as the Optionee's attorney-in-
fact and proxy, with full power of substitution, for and in the Optionee's name,
to vote, express consent or disapproval, or otherwise act in

                                      -3-
<PAGE>

such manner (including pursuant to written consent) and upon such matters as
Banyan or its designee(s), proxy or substitute(s) shall, in its or their sole
discretion, deem proper with respect to any and all of the shares issued upon
any exercise of this option or issued in respect to such shares as a stock
dividend, stock split or otherwise (collectively, for purposes of Sections 7, 8
and 9 hereof, the "Shares"). The proxy granted hereby shall be irrevocable and
may be exercised at any meeting or in respect of any written consent of
stockholders. This proxy is coupled with an interest sufficient in law to
support such proxy. This proxy shall remain in full force and effect and be
enforceable against any donee, transferee or assignee of the stock. In addition
to any other applicable limitations pursuant to the terms of this option, the
Optionee agrees not to sell, assign, transfer, loan, tender, pledge,
hypothecate, exchange, encumber or otherwise dispose of, or issue an option or
call with respect to, any of the Shares, or impair such Shares, in each case
unless, and as a condition precedent thereto, the transferee of such Shares
executes and delivers to Banyan an agreement to be bound by the terms of this
Section 7. Any purported transfer in violation of this Section 7 shall be null
and void and shall not be recognized by the Company or reflected on the stock
records of the Company. The Optionee shall cause the Company to require any
certificates representing any and all Shares issued upon any exercise of this
option to bear a legend referencing the restrictions on transfer set for in this
Section 7, which legend shall be subject to the approval of Banyan.
Notwithstanding anything to the contrary in the foregoing, the provisions of,
including, without limitation, the proxy appointed by, this Section 7 shall
terminate upon the closing of the Company's initial public offering,
underwritten by a nationally recognized underwriter, pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the
"Securities Act").

     8.   Repurchase of Shares Upon Termination of Employment.  The following
          ---------------------------------------------------
repurchase provisions shall apply to any and all Shares;

          (a)  Repurchase Rights.  If the Optionee for any reason whatsoever
               -----------------
(including without limitation death, disability, or voluntary or involuntary
termination) ceases to be employed by the Company prior to the date specified in
Section 8(d) below for the expiration of these restrictions, then during the 90-
day period following such termination the Company may elect, by written notice
delivered to the Optionee, to repurchase all or any portion of the Shares, at a
price per share equal to the fair market value of such Shares as of the close of
business on the date of termination of the Optionee's employment.  Such fair
market value shall be determined by mutual agreement of the Company and the
Optionee.  Failing such agreement between the Optionee and the Company within 30
days of the date of the Company's notice electing to repurchase such Shares, the
fair market value of such Shares shall be determined by three appraisers, one
designated within five days after the termination of said 30-day period by the
Optionee or his or her legal representatives (which appraiser shall not be the
Optionee or his or her legal representative), one within said period of five
days by the Company (which appraiser shall not be an officer, director or
employee of the Company) and the third within five days after said appointment
last occurring by the two appraisers so chosen.  Successor appraisers, if any
shall be required, shall be appointed, within a reasonable time, as nearly as
may be in the manner provided as to the related original appointment.  No
appointment shall be deemed as having been accomplished unless such appraiser
shall have accepted in writing his appointment as such within the time limited
for his appointment.  Notice of each appointment of an appraiser shall be given
promptly to the other parties in interest.  Any expenses relating to the
appointment and service of an appraiser shall be paid by the party appointing
such appraiser or, in the case of the appraiser appointed by the appraisers
chosen by the Company and the Optionee, shall be paid by the Company.  Said
appraisers shall proceed promptly to determine the fair market value of said
Share or Shares by agreement of any two of the appraisers, which shall be
conclusive upon all parties in interest in such Shares.  Promptly following such
determination, the appraisers shall mail or deliver such notice of such
determination to the Optionee and the Company.

          (b)  Repurchase Procedure. Upon notice from the Company of exercise of
               --------------------
its rights under this Section 8 and determination of the purchase price for the
Shares so repurchased, the Optionee shall transfer the Shares or appropriate
part thereof to the Company against payment by the Company of the purchase price
therefor.  If upon the expiration of the 90-day period following the Optionee's
termination of employment the Company shall have failed to elect to repurchase
all of the Shares, the repurchase rights with respect to the Shares not so
elected to be repurchased imposed by this Section 8 shall terminate, and the
Optionee or his or her legal representatives may thereafter transfer such
Shares.  The Optionee or his or her legal representatives may in no event
transfer any Shares prior thereto, other than to the Company.

          (c)  Failure of Optionee to Comply.  If the Optionee fails to comply
               -----------------------------
with any of the provisions of this Section 8, the Company, at its option and in
addition to its other remedies, may suspend the rights of the Optionee to vote
and to receive dividends on the Shares, or may refuse to register on its books
any transfer or change in the ownership of the Shares or in the right to vote
thereon, until the provisions of this Section 8 are complied with to the
satisfaction of the Company.

          (d)  Expiration.  The restriction contained in this Section 8 shall
               ----------
expire upon the closing of the Company's initial public offering, underwritten
by a nationally recognized underwriter, pursuant to an effective registration
statement under the Securities Act of 1933, as amended (the "Securities Act")
(such expiration date shall be referred to herein as the "Expiration Date").

          (e)  Safekeeping.  The Optionee acknowledges that the Company may, in
               -----------
its discretion, retain for safekeeping stock certificates representing all
Shares purchased hereunder by the Optionee.  The Optionee further acknowledges
that the Company may, to insure that the Optionee complies with the restriction
of this Section 8, continue to retain such stock certificates until the earlier
of the Expiration Date or the date of expiration of these repurchase rights
under Section 8(b) above.  At the time of any exercise of this option, in whole
or in part, the Optionee shall execute such further agreement as the Company may
require to implement the foregoing.

     9.   Right of First Refusal.
          ----------------------

          (a)  General.  The Optionee shall not sell, assign, pledge, or in any
               -------
manner transfer any of the Shares or any right or interest therein, whether
voluntarily or by operation of law, or by gift or otherwise, except by a
transfer which meets the requirements of the provisions of this Section 9.

          (b)  Restrictions on Transfer. If at any time or from time to time the
               ------------------------
Optionee intends to sell or transfer any Shares to a third party, the Optionee
shall provide notice thereof to the Company prior to such transfer (which in the
case of a sale shall include a bona fide purchase agreement with a viable
purchaser).  The Company shall have an option for 30 days following the date of
receipt of the Optionee's notice to purchase such Shares on the terms upon which
the Shares were to be purchased by or transferred to the third party by the
Optionee.  If the Company does not exercise its right of first refusal under
this Section 9(b) with respect to such proposed sale or transfer within such 30-
day period, the Optionee shall be free to sell or transfer such Shares to the
third party identified in the Optionee's notice for a period of 45 days after
the expiration of the 30-day period following the date of receipt of the
Optionee's notice.  Such sale or transfer must be on terms no more favorable to
the recipient than those set forth in the Optionee's notice.  In no event may
Shares be sold or transferred to any then-current competitor of the Company.
Any transfer or sale of Shares by the Optionee will be conditional upon the
recipient acknowledging in writing the option set forth in this Section 9(b) and
the other restrictions to which the Shares are subject.

                                      -5-
<PAGE>

          (c)  Failure of Optionee to Comply.  If the Optionee's notice in
               -----------------------------
respect of any Shares is not received by the Company as provided in Section 9(b)
above, or if the Optionee fails to comply with the provisions of Section 9(b)
above in respect of any such Shares in any other regard, the Company, at its
option and in addition to its other remedies, may suspend the rights to vote or
to receive dividends on said Shares, or may refuse to register on its books any
transfer or change in ownership of said Shares or in the right to vote thereon,
until the provisions of Section 9(b) are complied with to the satisfaction of
the Company; and if the required Optionee's notice is not received by the
Company after written demand by the Company, the Company may also independently
proceed as though a proper Optionee's notice has been received at the expiration
of ten days after mailing such demand, and, if the Company exercises its rights
under Section 9(b) with respect to said Shares or any of them, the Shares
specified shall be transferred accordingly.

          (d)  Expiration.  The Company's right of first refusal contained in
               ----------
this Section 9 with respect to any sale or transfer of Shares shall expire upon
the Expiration Date.

     10.  No Special Employment Rights.  Nothing contained in the Plan or this
          ----------------------------
option shall be construed or deemed by any person under any circumstances to
bind the Company to continue the employment of the Optionee for the period
within which this option may be exercised.

     11.  Rights as a Shareholder.  The Optionee shall have no rights as a
          -----------------------
shareholder with respect to any shares which may be purchased by exercise of
this option (including, without limitation, any rights to receive dividends or
non-cash distributions with respect to such shares) unless and until a
certificate representing such shares is duly issued and delivered to the
Optionee.  No adjustment shall be made for dividends or other rights for which
the record date is prior to the date such stock certificate is issued.

     12.  Adjustment Provisions.
          ---------------------

          (a)  General.  In the event of a consolidation, merger or other
               -------
reorganization in which all of the outstanding shares of Common Stock are
exchanged for securities, cash or other property of any other corporation or
business entity (an "Acquisition") or in the event of a liquidation of the
Company, the Board of Directors of the Company or the board of directors of any
corporation assuming the obligations of the Company, may, in its discretion,
take any one or more of the following actions as to this option:  (i) provide
that this option shall be assumed, or a substantially equivalent option shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof) on such terms as the Board determines to be appropriate, (ii) upon
written notice to the Optionee, provide that if unexercised, this option will
terminate immediately prior to the consummation of such transaction unless
exercised by the Optionee within a specified period following the date of such
notice, (iii) in the event of an Acquisition under the terms of which holders of
the Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the Acquisition (the "Acquisition Price"),
make or provide for a cash payment to the Optionee equal to the difference
between (A) the Acquisition Price times the number of shares of Common Stock
subject to outstanding options (to the extent then exercisable at prices not in
excess of the Acquisition Price) and (B) the aggregate exercise price of all
such outstanding options in exchange for the termination of such options, and
(iv) provide that all or any outstanding options shall become exercisable or
realizable in full prior to the effective date of such Acquisition.

          (b)  Board Authority to Make Adjustments.  Any adjustments under this
               -----------------------------------
Section 12 will be made by the Board of Directors, whose determination as to
what adjustments, if any, will be made

                                      -6-
<PAGE>

and the extent thereof will be final, binding and conclusive. No fractional
shares will be issued pursuant to this option on account of any such
adjustments.

     13.  Withholding Taxes.  The Company's obligation to deliver shares upon
          -----------------
the exercise of this option shall be subject to the Optionee's satisfaction of
all applicable federal, state and local income and employment tax withholding
requirements.  The Optionee shall pay to the Company, or make provision
satisfactory to the Board for payment of, any taxes required by law to be
withheld in respect of options under the Plan no later than the date of the
event creating the tax liability.  In the Board's discretion, and subject to
such conditions as the Board may establish, such tax obligations may be paid in
whole or in part in shares of Common Stock, including shares retained from the
option creating the tax obligation, valued at their fair market value.  The
Company may, to the extent permitted by law, deduct any such tax obligations
from any payment of any kind otherwise due to the Optionees.

     14.  Limitations on Disposition of Incentive Stock Option Shares.  It is
          -----------------------------------------------------------
understood and intended that this option shall qualify as an "incentive stock
option" as defined in Section 422 of the Code.  Accordingly, the Optionee
understands that in order to obtain the benefits of an incentive stock option
under Section 421 of the Code, no sale or other disposition may be made of any
shares acquired upon exercise of the option within one year after the day of the
transfer of such shares to him, nor within two years after the grant of the
option.  If the Optionee intends to dispose, or does dispose (whether by sale,
exchange, gift, transfer or otherwise), of any such shares within said periods,
he or she will notify the Company in writing within ten days after such
disposition.


     15.  Investment Representations; Legends.
          -----------------------------------

          (a)  Representations.  The Optionee represents, warrants and covenants
               ---------------
that:

               (i)   Any shares purchased upon exercise of this option shall be
               acquired for the Optionee's account for investment only and not
               with a view to, or for sale in connection with, any distribution
               of the shares in violation of the Securities Act or any rule or
               regulation under the Securities Act.

               (ii)  The Optionee has had such opportunity as he or she has
               deemed adequate to obtain from representatives of the Company
               such information as is necessary to permit the Optionee to
               evaluate the merits and risks of his or her investment in the
               Company.

               (iii) The Optionee is able to bear the economic risk of holding
               shares acquired pursuant to the exercise of this option for an
               indefinite period.

               (iv)  The Optionee understands that (A) the shares acquired
               pursuant to the exercise of this option will not be registered
               under the Securities Act and are "restricted securities" within
               the meaning of Rule 144 under the Securities Act; (B) such shares
               cannot be sold, transferred or otherwise disposed of unless they
               are subsequently registered under the Securities Act or an
               exemption from registration is then available; (C) in any event,
               an exemption from registration under Rule 144 or otherwise under
               the Securities Act may not be available for at least two years
               and even then will not be available unless a public market then
               exists for the Common Stock, adequate information concerning the
               Company is

                                      -7-
<PAGE>

               then available to the public and other terms and conditions of
               Rule 144 are complied with; and (D) there is now no registration
               statement on file with the Securities and Exchange Commission
               with respect to any stock of the Company and the Company has no
               obligation or current intention to register any shares acquired
               pursuant to the exercise of this option under the Securities Act.

               (v)   The Optionee agrees that, if the Company offers for the
               first time any of its Common Stock for sale pursuant to a
               registration statement under the Securities Act, the Optionee
               will not, without the prior written consent of the Company,
               publicly offer, sell, contract to sell or otherwise dispose of,
               directly or indirectly, any shares purchased upon exercise of
               this option for a period of 180 days after the effective date of
               such registration statement.

By making payment upon exercise of this option, the Optionee shall be deemed to
have reaffirmed, as of the date of such payment, the representations made in
this Section 15.

          (b)  Legends on Stock Certificates.  All stock certificates
               -----------------------------
representing shares of Common Stock issued to the Optionee upon exercise of this
option shall have affixed thereto legends substantially in the following forms,
in addition to any other legends required by applicable state law:


          "The shares of stock represented by this certificate have not been
          registered under the Securities Act of 1933 and may not be
          transferred, sold or otherwise disposed of in the absence of an
          effective registration statement with respect to the shares evidenced
          by this certificate, filed and made effective under the Securities Act
          of 1933, or an opinion of counsel satisfactory to the Company to the
          effect that registration under such Act is not required."

          "The shares of stock represented by this certificate are subject to
          certain restrictions on transfer and repurchase rights contained in an
          Option Agreement, a copy of which will be furnished upon request by
          the issuer."

To ensure compliance with the terms of this agreement, the Company may issue to
its transfer agent appropriate stop transfer instructions with respect to the
Shares.

     16.  Miscellaneous.
          -------------

          (a)  The Board may amend, modify or terminate any outstanding option,
including substituting therefor another option of the same or a different type,
changing the date of exercise or realization, provided that the Optionee's
consent to such action shall be required unless the Board determines that the
action, taking into account any related action, would not materially and
adversely affect the Optionee.  The Board may at any time accelerate the time at
which all or any part of an Option may be exercised.

          (b)  All notices under this option shall be mailed or delivered by
hand to the parties at their respective addresses set forth beneath their names
below or at such other address as may be designated in writing by either of the
parties to one another.

          (c)  This option shall be governed by and construed in accordance with
the laws of the State of Delaware.

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

                           SWITCHBOARD INCORPORATED

                       INCENTIVE STOCK OPTION AGREEMENT

     1.   Grant of Option.    Switchboard Incorporated, a Delaware Corporation
          ----------------
(the "Company"), hereby grants to John P. Jewett (the "Optionee"), an option,
pursuant to the Company's 1996 Stock Incentive Plan (the "Plan"), to purchase an

(the "Code").

     2.   Incentive Stock Option.  To the extent permitted by applicable law,
          -----------------------
this option is intended to qualify as an incentive stock option ("Incentive
Stock Option") within the meaning of Section 422 of the Code.

     3.   Exercise of Option and Provisions for Termination.
          -------------------------------------------------

          (a)  Vesting Schedule.  Except as otherwise provided in this
               ----------------
Agreement, this option may be exercised prior to the tenth anniversary of the
date of grant (hereinafter the "Final Exercise Date") in installments as to not
more than the number of shares set forth in the table below during the
respective installment periods set forth below.

               (i)   Ten thousand (10,000) shares will vest on the earlier of
                     (A) the effective date of the initial registration of the
                     Company's Common Stock under the Securities Act of 1933, as
                     amended or (B) five (5) years from the date of grant;

               (ii)  Fifteen thousand (15,000) shares will vest on the earlier
                     of (A) the date that the Company's Market Capitalization
                     equals or exceeds two billion dollars for a period of one-
                     hundred and eighty (180) consecutive calendar days or (B)

                     (2) years from the date of grant.

The right of exercise shall be cumulative so that if the option is not exercised
to the maximum extent permissible during any exercise period, it shall be
exercisable, in whole or in part, with respect to all shares not so purchased at
any time prior to the Final Exercise Date or the earlier termination of this
option.  This option may not be exercised at any time on or after the Final
Exercise Date.
<PAGE>

     For the purposes of this provision 3(a), "Market Capitalization" means the
number of outstanding shares of Common Stock of the Company multiplied by the
"fair market value" of a share of Common Stock as of a particular date (the
"Determination Date").  The "fair market value" shall mean:  (I) if shares of
Common Stock are traded on a national securities exchange (an "Exchange"), the
average of the closing prices of a share of the Common Stock of the Company on
the last twenty (20) trading days prior to the Determination Date reported on
such Exchange as reported in The Wall Street Journal or comparable reporting
service; or (ii) if shares of Common Stock are not traded on an Exchange but
trade in the over-the-counter market and such shares are quoted on the Nasdaq
National Market System or the Nasdaq Small-Cap Market (either, "NASDAQ"), (A)
the average of the last sale prices reported on NASDAQ or (B) if such shares are
an issue for which last sale prices are not reported on NASDAQ, the average of
the closing bid and ask prices, in each case on the last twenty (20) trading
days (or if the relevant price or quotation did not exist on any of such days,
the relevant price or quotation on the next preceding business day on which
there was such a price or quotation) prior to the Determination Date as reported
in The Wall Street Journal or comparable reporting service; or (iii) if no price
can be determined on the basis of the above methods of valuation, then the
judgment of valuation shall be determined in good faith by the Board of
Directors of the Company, which determination shall be described in a duly
adopted board resolution certified by the Company's Clerk or Assistant Clerk.

          (b)  Exercise Procedure.  Subject to the conditions set forth in this
               ------------------
Agreement, this option shall be exercised by the Optionee's delivery of written
notice of exercise to the Treasurer of the Company, specifying the number of
shares to be purchased and the purchase price to be paid therefor and
accompanied by payment in full in accordance with Section 4.  Such exercise
shall be effective upon receipt by the Treasurer of the Company of such written
notice together with the required payment.  The Optionee may purchase less than
the number of shares covered hereby, provided that no partial exercise of this
option may be for any fractional share or for fewer than ten whole shares.

          (C)  Continuous Employment Required.  This option may not be exercised
               ------------------------------
unless the Optionee, at the time he or she exercises this option, is, and has
been at all times since the date of grant of this option, an employee of the
Company.  For all purposes of this option, (I) "employment" shall be defined in
accordance with the provisions of Section 1.421-7(h) of the Income Tax
Regulations or any successor regulations, and (ii) if this option shall be
assumed or a new option substituted therefor in a transaction to which Section
424(a) of the Code applies, employment by such assuming or substituting
corporation (hereinafter called the "Successor Corporation") shall be considered
for all purposes of this option to be employment by the Company.

          (d)  Termination of Employment.  If the Optionee ceases to be employed
               -------------------------
by the Company for any reason (including without limitation death, disability,
or voluntary or involuntary termination), then the right to exercise this option
shall terminate 90 days after such cessation (but in no event after the Final
Exercise Date, provided, that, this option shall be exercisable only to the
               --------  ----
extent that the Optionee was entitled to exercise this option on the date of
such cessation.

          (e) Early Exercise Alternative.  Notwithstanding the exercisability
              --------------------------
schedule set forth in paragraph (a), the Optionee may elect to exercise this
option as to the unvested shares (in addition to the vested shares) if
simultaneously with such exercise the Optionee enters into a Stock
Restriction Agreement with the Company in the form attached hereto as Exhibit A
                                                                      ---------
(the "Stock Restriction Agreement"). The Stock Restriction Agreement provides
that the unvested shares shall be subject to a right of repurchase (the
"Purchase Option") in favor of the Company at the $9.00 exercise price (as
adjusted pursuant to the terms hereof) in the event that the Optionee ceases to
be employed by the Company.

     4.   Payment of Purchase Price.
          -------------------------

          (a)  Method of Payment.  Payment of the purchase price for shares
               -----------------
purchased upon exercise of this option shall be made by delivery of cash or a
check in an amount equal to the exercise price of such option or, with the prior
consent of the Company (which may be withheld in its sole discretion), by (A)
delivery of shares of Common Stock owned by the Optionee for at least six
months, valued at their fair market value, as determined in (b) below, (B)
delivery of a promissory note of the Optionee to the Company on terms determined
by the Board, (C) delivery of an irrevocable undertaking by a broker to deliver
promptly to the Company sufficient funds to pay the exercise price or delivery
of

                                      -2-
<PAGE>

irrevocable instructions to a broker to deliver promptly to the Company cash or
a check sufficient to pay the exercise price, (D) payment of such other lawful
consideration as the Board may determine, or (E) any combination of the
foregoing.

          (b)  Valuation of Shares or Other Non-Cash Consideration Tendered in
               ---------------------------------------------------------------
Payment of Purchase Price.  For the purposes hereof, the fair market value of
- -------------------------
any share of the Company's Common Stock or other non-cash consideration which
may be delivered to the Company in exercise of this option shall be determined
in good faith by the Board of Directors of the Company.

          (C)  Delivery of Shares Tendered in Payment of Purchase Price.  If the
               --------------------------------------------------------
Optionee exercises this option by delivery of shares of Common Stock of the
Company, the certificate or certificates representing the shares of Common Stock
of the Company to be delivered shall be duly executed in blank by the Optionee
or shall be accompanied by a stock power duly executed in blank suitable for
purposes of transferring such shares to the Company.  Fractional shares of
Common Stock of the Company will not be accepted in payment of the purchase
price of shares acquired upon exercise of this option.

          (d)  Restrictions on Use of Option Stock.  Notwithstanding the
               -----------------------------------
foregoing, no shares of Common Stock of the Company may be tendered in payment
of the purchase price of shares purchased upon exercise of this option if the
shares to be so tendered were acquired within six (6) months before the date of
such tender, through the exercise of an option granted under the Plan or any
other stock option or restricted stock plan of the Company.

     5.   Delivery of Shares; Compliance With Securities Laws, Etc.
          --------------------------------------------------------

          (a)  General.  The Company shall, upon payment of the option price for
               -------
the number of shares purchased and paid for, make prompt delivery of such shares
to the Optionee, provided that if any law or regulation requires the Company to
                 -------- ----
take any action with respect to such shares before the issuance thereof, then
the date of delivery of such shares shall be extended for the period necessary
to complete such action.

          (b)  Compliance With Securities Laws, Etc.  The Company will not be
               ------------------------------------
obligated to deliver any shares of Common Stock pursuant to the Plan or to
remove restriction from shares previously delivered under the Plan (I) until all
conditions of the option have been satisfied or removed, (ii) until, in the
opinion of the Company's counsel, all applicable federal and state laws and
regulation have been complied with, (iii) if the outstanding Stock is at the
time listed on any stock exchange, until the shares to be delivered have been
listed or authorized to be listed on such exchange upon official notice of
issuance, and (iv) until all other legal matters in connection with the issuance
and delivery of such shares have been approved by the Company's counsel.

     6.   Nontransferability of Option.  This option is personal and no rights
          ----------------------------
granted hereunder may be transferred, assigned, pledged or hypothecated in any
way (whether by operation of law or otherwise) nor shall any such rights be
subject to execution, attachment or similar process.  Upon any attempt to
transfer, assign, pledge, hypothecate or otherwise dispose of this option or of
such rights contrary to the provisions hereof, or upon the levy of any
attachment or similar process upon this option or such rights, this option and
such rights shall, at the election of the Company, become null and void.

     7.   Proxy.  The Optionee hereby appoints Banyan Worldwide, a Massachusetts
          -----
corporation, and/or its designee(s) ("Banyan"), as the Optionee's attorney-in-
fact and proxy, with full power of substitution, for and in the Optionee's name,
to vote, express consent or disapproval, or otherwise act in

                                      -3-
<PAGE>

such manner (including pursuant to written consent) and upon such matters as
Banyan or its designee(s), proxy or substitute(s) shall, in its or their sole
discretion, deem proper with respect to any and all of the shares issued upon
any exercise of this option or issued in respect to such shares as a stock
dividend, stock split or otherwise (collectively, for purposes of Sections 7, 8
and 9 hereof, the "Shares"). The proxy granted hereby shall be irrevocable and
may be exercised at any meeting or in respect of any written consent of
stockholders. This proxy is coupled with an interest sufficient in law to
support such proxy. This proxy shall remain in full force and effect and be
enforceable against any donee, transferee or assignee of the stock. In addition
to any other applicable limitations pursuant to the terms of this option, the
Optionee agrees not to sell, assign, transfer, loan, tender, pledge,
hypothecate, exchange, encumber or otherwise dispose of, or issue an option or
call with respect to, any of the Shares, or impair such Shares, in each case
unless, and as a condition precedent thereto, the transferee of such Shares
executes and delivers to Banyan an agreement to be bound by the terms of this
Section 7. Any purported transfer in violation of this Section 7 shall be null
and void and shall not be recognized by the Company or reflected on the stock
records of the Company. The Optionee shall cause the Company to require any
certificates representing any and all Shares issued upon any exercise of this
option to bear a legend referencing the restrictions on transfer set for in this
Section 7, which legend shall be subject to the approval of Banyan.
Notwithstanding anything to the contrary in the foregoing, the provisions of,
including, without limitation, the proxy appointed by, this Section 7 shall
terminate upon the closing of the Company's initial public offering,
underwritten by a nationally recognized underwriter, pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the
"Securities Act").

     8.   Repurchase of Shares Upon Termination of Employment. The following
          ---------------------------------------------------
repurchase provisions shall apply to any and all Shares;

          (a)  Repurchase Rights.  If the Optionee for any reason whatsoever
               -----------------
(including without limitation death, disability, or voluntary or involuntary
termination) ceases to be employed by the Company prior to the date specified in
Section 8(d) below for the expiration of these restrictions, then during the 90-
day period following such termination the Company may elect, by written notice
delivered to the Optionee, to repurchase all or any portion of the Shares, at a
price per share equal to the fair market value of such Shares as of the close of
business on the date of termination of the Optionee's employment.  Such fair
market value shall be determined by mutual agreement of the Company and the
Optionee.  Failing such agreement between the Optionee and the Company within 30
days of the date of the Company's notice electing to repurchase such Shares, the
fair market value of such Shares shall be determined by three appraisers, one
designated within five days after the termination of said 30-day period by the
Optionee or his or her legal representatives (which appraiser shall not be the
Optionee or his or her legal representative), one within said period of five
days by the Company (which appraiser shall not be an officer, director or
employee of the Company) and the third within five days after said appointment
last occurring by the two appraisers so chosen.  Successor appraisers, if any
shall be required, shall be appointed, within a reasonable time, as nearly as
may be in the manner provided as to the related original appointment.  No
appointment shall be deemed as having been accomplished unless such appraiser
shall have accepted in writing his appointment as such within the time limited
for his appointment.  Notice of each appointment of an appraiser shall be given
promptly to the other parties in interest.  Any expenses relating to the
appointment and service of an appraiser shall be paid by the party appointing
such appraiser or, in the case of the appraiser appointed by the appraisers
chosen by the Company and the Optionee, shall be paid by the Company.  Said
appraisers shall proceed promptly to determine the fair market value of said
Share or Shares by agreement of any two of the appraisers, which shall be
conclusive upon all parties in interest in such Shares.  Promptly following such
determination, the appraisers shall mail or deliver such notice of such
determination to the Optionee and the Company.

                                      -4-
<PAGE>

          (b)  Repurchase Procedure. Upon notice from the Company of exercise of
               --------------------
its rights under this Section 8 and determination of the purchase price for the
Shares so repurchased, the Optionee shall transfer the Shares or appropriate
part thereof to the Company against payment by the Company of the purchase price
therefor.  If upon the expiration of the 90-day period following the Optionee's
termination of employment the Company shall have failed to elect to repurchase
all of the Shares, the repurchase rights with respect to the Shares not so
elected to be repurchased imposed by this Section 8 shall terminate, and the
Optionee or his or her legal representatives may thereafter transfer such
Shares.  The Optionee or his or her legal representatives may in no event
transfer any Shares prior thereto, other than to the Company.

          (C)  Failure of Optionee to Comply.  If the Optionee fails to comply
               -----------------------------
with any of the provisions of this Section 8, the Company, at its option and in
addition to its other remedies, may suspend the rights of the Optionee to vote
and to receive dividends on the Shares, or may refuse to register on its books
any transfer or change in the ownership of the Shares or in the right to vote
thereon, until the provisions of this Section 8 are complied with to the
satisfaction of the Company.

          (d)  Expiration.  The restriction contained in this Section 8 shall
               ----------
expire upon the closing of the Company's initial public offering, underwritten
by a nationally recognized underwriter, pursuant to an effective registration
statement under the Securities Act of 1933, as amended (the "Securities Act")
(such expiration date shall be referred to herein as the "Expiration Date").

          (e)  Safekeeping.  The Optionee acknowledges that the Company may, in
               -----------
its discretion, retain for safekeeping stock certificates representing all
Shares purchased hereunder by the Optionee.  The Optionee further acknowledges
that the Company may, to insure that the Optionee complies with the restriction
of this Section 8, continue to retain such stock certificates until the earlier
of the Expiration Date or the date of expiration of these repurchase rights
under Section 8(b) above.  At the time of any exercise of this option, in whole
or in part, the Optionee shall execute such further agreement as the Company may
require to implement the foregoing.

     9.   Right of First Refusal.
          ----------------------

          (a)  General.  The Optionee shall not sell, assign, pledge, or in any
               -------
manner transfer any of the Shares or any right or interest therein, whether
voluntarily or by operation of law, or by gift or otherwise, except by a
transfer which meets the requirements of the provisions of this Section 9.

          (b)  Restrictions on Transfer. If at any time or from time to time the
               ------------------------
Optionee intends to sell or transfer any Shares to a third party, the Optionee
shall provide notice thereof to the Company prior to such transfer (which in the
case of a sale shall include a bona fide purchase agreement with a viable
purchaser).  The Company shall have an option for 30 days following the date of
receipt of the Optionee's notice to purchase such Shares on the terms upon which
the Shares were to be purchased by or transferred to the third party by the
Optionee.  If the Company does not exercise its right of first refusal under
this Section 9(b) with respect to such proposed sale or transfer within such 30-
day period, the Optionee shall be free to sell or transfer such Shares to the
third party identified in the Optionee's notice for a period of 45 days after
the expiration of the 30-day period following the date of receipt of the
Optionee's notice.  Such sale or transfer must be on terms no more favorable to
the recipient than those set forth in the Optionee's notice.  In no event may
Shares be sold or transferred to any then-current competitor of the Company.
Any transfer or sale of Shares by the Optionee will be conditional upon the
recipient acknowledging in writing the option set forth in this Section 9(b) and
the other restrictions to which the Shares are subject.

                                      -5-
<PAGE>

          (C)  Failure of Optionee to Comply.  If the Optionee's notice in
               -----------------------------
respect of any Shares is not received by the Company as provided in Section 9(b)
above, or if the Optionee fails to comply with the provisions of Section 9(b)
above in respect of any such Shares in any other regard, the Company, at its
option and in addition to its other remedies, may suspend the rights to vote or
to receive dividends on said Shares, or may refuse to register on its books any
transfer or change in ownership of said Shares or in the right to vote thereon,
until the provisions of Section 9(b) are complied with to the satisfaction of
the Company; and if the required Optionee's notice is not received by the
Company after written demand by the Company, the Company may also independently
proceed as though a proper Optionee's notice has been received at the expiration
of ten days after mailing such demand, and, if the Company exercises its rights
under Section 9(b) with respect to said Shares or any of them, the Shares
specified shall be transferred accordingly.

          (d)  Expiration.  The Company's right of first refusal contained in
               ----------
this Section 9 with respect to any sale or transfer of Shares shall expire upon
the Expiration Date.

     10.  No Special Employment Rights.  Nothing contained in the Plan or this
          ----------------------------
option shall be construed or deemed by any person under any circumstances to
bind the Company to continue the employment of the Optionee for the period
within which this option may be exercised.

     11.  Rights as a Shareholder.  The Optionee shall have no rights as a
          -----------------------
shareholder with respect to any shares which may be purchased by exercise of
this option (including, without limitation, any rights to receive dividends or
non-cash distributions with respect to such shares) unless and until a
certificate representing such shares is duly issued and delivered to the
Optionee.  No adjustment shall be made for dividends or other rights for which
the record date is prior to the date such stock certificate is issued.

     12.  Adjustment Provisions.
          ---------------------

          (a)  General.  In the event of a consolidation, merger or other
               -------
reorganization in which all of the outstanding shares of Common Stock are
exchanged for securities, cash or other property of any other corporation or
business entity (an "Acquisition") or in the event of a liquidation of the
Company, the Board of Directors of the Company or the board of directors of any
corporation assuming the obligations of the Company, may, in its discretion,
take any one or more of the following actions as to this option:  (I) provide
that this option shall be assumed, or a substantially equivalent option shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof) on such terms as the Board determines to be appropriate, (ii) upon
written notice to the Optionee, provide that if unexercised, this option will
terminate immediately prior to the consummation of such transaction unless
exercised by the Optionee within a specified period following the date of such
notice, (iii) in the event of an Acquisition under the terms of which holders of
the Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the Acquisition (the "Acquisition Price"),
make or provide for a cash payment to the Optionee equal to the difference
between (A) the Acquisition Price times the number of shares of Common Stock
subject to outstanding options (to the extent then exercisable at prices not in
excess of the Acquisition Price) and (B) the aggregate exercise price of all
such outstanding options in exchange for the termination of such options, and
(iv) provide that all or any outstanding options shall become exercisable or
realizable in full prior to the effective date of such Acquisition.

          (b)  Board Authority to Make Adjustments.  Any adjustments under this
               -----------------------------------
Section 12 will be made by the Board of Directors, whose determination as to
what adjustments, if any, will be made

                                      -6-
<PAGE>

and the extent thereof will be final, binding and conclusive. No fractional
shares will be issued pursuant to this option on account of any such
adjustments.

     13.  Withholding Taxes.  The Company's obligation to deliver shares upon
          -----------------
the exercise of this option shall be subject to the Optionee's satisfaction of
all applicable federal, state and local income and employment tax withholding
requirements.  The Optionee shall pay to the Company, or make provision
satisfactory to the Board for payment of, any taxes required by law to be
withheld in respect of options under the Plan no later than the date of the
event creating the tax liability.  In the Board's discretion, and subject to
such conditions as the Board may establish, such tax obligations may be paid in
whole or in part in shares of Common Stock, including shares retained from the
option creating the tax obligation, valued at their fair market value.  The
Company may, to the extent permitted by law, deduct any such tax obligations
from any payment of any kind otherwise due to the Optionees.

     14.  Limitations on Disposition of Incentive Stock Option Shares.  It is
          -----------------------------------------------------------
understood and intended that this option shall qualify as an "incentive stock
option" as defined in Section 422 of the Code.  Accordingly, the Optionee
understands that in order to obtain the benefits of an incentive stock option
under Section 421 of the Code, no sale or other disposition may be made of any
shares acquired upon exercise of the option within one year after the day of the
transfer of such shares to him, nor within two years after the grant of the
option.  If the Optionee intends to dispose, or does dispose (whether by sale,
exchange, gift, transfer or otherwise), of any such shares within said periods,
he or she will notify the Company in writing within ten days after such
disposition.

     15.  Investment Representations; Legends.
          -----------------------------------

          (a)  Representations.  The Optionee represents, warrants and covenants
               ---------------
that:

               (i)   Any shares purchased upon exercise of this option shall be
               acquired for the Optionee's account for investment only and not
               with a view to, or for sale in connection with, any distribution
               of the shares in violation of the Securities Act or any rule or
               regulation under the Securities Act.

               (ii)  The Optionee has had such opportunity as he or she has
               deemed adequate to obtain from representatives of the Company
               such information as is necessary to permit the Optionee to
               evaluate the merits and risks of his or her investment in the
               Company.

               (iii) The Optionee is able to bear the economic risk of holding
               shares acquired pursuant to the exercise of this option for an
               indefinite period.

               (iv)  The Optionee understands that (A) the shares acquired
               pursuant to the exercise of this option will not be registered
               under the Securities Act and are "restricted securities" within
               the meaning of Rule 144 under the Securities Act; (B) such shares
               cannot be sold, transferred or otherwise disposed of unless they
               are subsequently registered under the Securities Act or an
               exemption from registration is then available; (C) in any event,
               an exemption from registration under Rule 144 or otherwise under
               the Securities Act may not be available for at least two years
               and even then will not be available unless a public market then
               exists for the Common Stock, adequate information concerning the
               Company is

                                      -7-
<PAGE>

               then available to the public and other terms and conditions of
               Rule 144 are complied with; and (D) there is now no registration
               statement on file with the Securities and Exchange Commission
               with respect to any stock of the Company and the Company has no
               obligation or current intention to register any shares acquired
               pursuant to the exercise of this option under the Securities Act.

               (v)   The Optionee agrees that, if the Company offers for the
               first time any of its Common Stock for sale pursuant to a
               registration statement under the Securities Act, the Optionee
               will not, without the prior written consent of the Company,
               publicly offer, sell, contract to sell or otherwise dispose of,
               directly or indirectly, any shares purchased upon exercise of
               this option for a period of 180 days after the effective date of
               such registration statement.

By making payment upon exercise of this option, the Optionee shall be deemed to
have reaffirmed, as of the date of such payment, the representations made in
this Section 15.

          (b)  Legends on Stock Certificates.  All stock certificates
               -----------------------------
representing shares of Common Stock issued to the Optionee upon exercise of this
option shall have affixed thereto legends substantially in the following forms,
in addition to any other legends required by applicable state law:

          "The shares of stock represented by this certificate have not been
          registered under the Securities Act of 1933 and may not be
          transferred, sold or otherwise disposed of in the absence of an
          effective registration statement with respect to the shares evidenced
          by this certificate, filed and made effective under the Securities Act
          of 1933, or an opinion of counsel satisfactory to the Company to the
          effect that registration under such Act is not required."

          "The shares of stock represented by this certificate are subject to
          certain restrictions on transfer and repurchase rights contained in an
          Option Agreement, a copy of which will be furnished upon request by
          the issuer."

To ensure compliance with the terms of this agreement, the Company may issue to
its transfer agent appropriate stop transfer instructions with respect to the
Shares.

     16.  Miscellaneous.
          -------------

          (a)  The Board may amend, modify or terminate any outstanding option,
including substituting therefor another option of the same or a different type,
changing the date of exercise or realization, provided that the Optionee's
consent to such action shall be required unless the Board determines that the
action, taking into account any related action, would not materially and
adversely affect the Optionee.  The Board may at any time accelerate the time at
which all or any part of an Option may be exercised.

          (b)  All notices under this option shall be mailed or delivered by
hand to the parties at their respective addresses set forth beneath their names
below or at such other address as may be designated in writing by either of the
parties to one another.

          (C)  This option shall be governed by and construed in accordance with
the laws of the State of Delaware.

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

                           SWITCHBOARD INCORPORATED

                       INCENTIVE STOCK OPTION AGREEMENT

     1.   Grant of Option.    Switchboard Incorporated, a Delaware Corporation
          ----------------
(the "Company"), hereby grants to James M. Canon (the "Optionee"), an option,
pursuant to the Company's 1996 Stock Incentive Plan (the "Plan"), to purchase an
aggregate of 50,000 shares of Common Stock, $.01 par value per share, of the

(the "Code").

     2.   Incentive Stock Option.  To the extent permitted by applicable law,
          -----------------------
this option is intended to qualify as an incentive stock option ("Incentive
Stock Option") within the meaning of Section 422 of the Code.

     3.   Exercise of Option and Provisions for Termination.
          -------------------------------------------------

          (a)  Vesting Schedule.  Except as otherwise provided in this
               ----------------
Agreement, this option may be exercised prior to the tenth anniversary of the

respective installment periods set forth below.

               (i)   Ten thousand (10,000) shares will vest on the earlier of
                     (A) the effective date of the initial registration of the
                     Company's Common Stock under the Securities Act of 1933, as
                     amended or (B) five (5) years from the date of grant;

               (ii)  Fifteen thousand (15,000) shares will vest on the earlier
                     of (A) the date that the Company's Market Capitalization
                     equals or exceeds two billion dollars for a period of one-
                     hundred and eighty (180) consecutive calendar days or (B)

               (iii) Twelve thousand five hundred (12,500) shares will vest on

                     period of ninety (90) consecutive calendar days or (B) two
                     (2) years from the date of grant.

The right of exercise shall be cumulative so that if the option is not exercised
to the maximum extent permissible during any exercise period, it shall be
exercisable, in whole or in part, with respect to all shares not so purchased at
any time prior to the Final Exercise Date or the earlier termination of this
option.  This option may not be exercised at any time on or after the Final
Exercise Date.
<PAGE>

     For the purposes of this provision 3(a), "Market Capitalization" means the
number of outstanding shares of Common Stock of the Company multiplied by the
"fair market value" of a share of Common Stock as of a particular date (the
"Determination Date"). The "fair market value" shall mean: (I) if shares of
Common Stock are traded on a national securities exchange (an "Exchange"), the
average of the closing prices of a share of the Common Stock of the Company on
the last twenty (20) trading days prior to the Determination Date reported on
such Exchange as reported in The Wall Street Journal or comparable reporting
service; or (ii) if shares of Common Stock are not traded on an Exchange but
trade in the over-the-counter market and such shares are quoted on the Nasdaq
National Market System or the Nasdaq Small-Cap Market (either, "NASDAQ"), (A)
the average of the last sale prices reported on NASDAQ or (B) if such shares are
an issue for which last sale prices are not reported on NASDAQ, the average of
the closing bid and ask prices, in each case on the last twenty (20) trading
days (or if the relevant price or quotation did not exist on any of such days,
the relevant price or quotation on the next preceding business day on which
there was such a price or quotation) prior to the Determination Date as reported
in The Wall Street Journal or comparable reporting service; or (iii) if no price
can be determined on the basis of the above methods of valuation, then the
judgment of valuation shall be determined in good faith by the Board of
Directors of the Company, which determination shall be described in a duly
adopted board resolution certified by the Company's Clerk or Assistant Clerk.

          (b)  Exercise Procedure.  Subject to the conditions set forth in this
               ------------------
Agreement, this option shall be exercised by the Optionee's delivery of written
notice of exercise to the Treasurer of the Company, specifying the number of
shares to be purchased and the purchase price to be paid therefor and
accompanied by payment in full in accordance with Section 4.  Such exercise
shall be effective upon receipt by the Treasurer of the Company of such written
notice together with the required payment.  The Optionee may purchase less than
the number of shares covered hereby, provided that no partial exercise of this
option may be for any fractional share or for fewer than ten whole shares.

          (C)  Continuous Employment Required.  This option may not be exercised
               ------------------------------
unless the Optionee, at the time he or she exercises this option, is, and has
been at all times since the date of grant of this option, an employee of the
Company.  For all purposes of this option, (I) "employment" shall be defined in
accordance with the provisions of Section 1.421-7(h) of the Income Tax
Regulations or any successor regulations, and (ii) if this option shall be
assumed or a new option substituted therefor in a transaction to which Section
424(a) of the Code applies, employment by such assuming or substituting
corporation (hereinafter called the "Successor Corporation") shall be considered
for all purposes of this option to be employment by the Company.

          (d)  Termination of Employment.  If the Optionee ceases to be employed
               -------------------------
by the Company for any reason (including without limitation death, disability,
or voluntary or involuntary termination), then the right to exercise this option
shall terminate 90 days after such cessation (but in no event after the Final
Exercise Date, provided, that, this option shall be exercisable only to the
               --------  ----
extent that the Optionee was entitled to exercise this option on the date of
such cessation.

          (e) Early Exercise Alternative.  Notwithstanding the exercisability
              --------------------------
schedule set forth in paragraph (a), the Optionee may elect to exercise this
option as to the unvested shares (in addition to the vested shares) if
simultaneously with such exercise the Optionee enters into a Stock
Restriction Agreement with the Company in the form attached hereto as Exhibit A
                                                                      ---------
(the "Stock Restriction Agreement"). The Stock Restriction Agreement provides
that the unvested shares shall be subject to a right of repurchase (the
"Purchase Option") in favor of the Company at the $9.00 exercise price (as
adjusted pursuant to the terms hereof) in the event that the Optionee ceases to
be employed by the Company.

     4.   Payment of Purchase Price.
          -------------------------

          (a)  Method of Payment.  Payment of the purchase price for shares
               -----------------
purchased upon exercise of this option shall be made by delivery of cash or a
check in an amount equal to the exercise price of such option or, with the prior
consent of the Company (which may be withheld in its sole discretion), by (A)
delivery of shares of Common Stock owned by the Optionee for at least six
months, valued at their fair market value, as determined in (b) below, (B)
delivery of a promissory note of the Optionee to the Company on terms determined
by the Board, (C) delivery of an irrevocable undertaking by a broker to deliver
promptly to the Company sufficient funds to pay the exercise price or delivery
of

                                      -2-
<PAGE>

irrevocable instructions to a broker to deliver promptly to the Company cash or
a check sufficient to pay the exercise price, (D) payment of such other lawful
consideration as the Board may determine, or (E) any combination of the
foregoing.

          (b)  Valuation of Shares or Other Non-Cash Consideration Tendered in
               ---------------------------------------------------------------
Payment of Purchase Price.  For the purposes hereof, the fair market value of
- -------------------------
any share of the Company's Common Stock or other non-cash consideration which
may be delivered to the Company in exercise of this option shall be determined
in good faith by the Board of Directors of the Company.

          (C)  Delivery of Shares Tendered in Payment of Purchase Price.  If the
               --------------------------------------------------------
Optionee exercises this option by delivery of shares of Common Stock of the
Company, the certificate or certificates representing the shares of Common Stock
of the Company to be delivered shall be duly executed in blank by the Optionee
or shall be accompanied by a stock power duly executed in blank suitable for
purposes of transferring such shares to the Company.  Fractional shares of
Common Stock of the Company will not be accepted in payment of the purchase
price of shares acquired upon exercise of this option.

          (d)  Restrictions on Use of Option Stock.  Notwithstanding the
               -----------------------------------
foregoing, no shares of Common Stock of the Company may be tendered in payment
of the purchase price of shares purchased upon exercise of this option if the
shares to be so tendered were acquired within six (6) months before the date of
such tender, through the exercise of an option granted under the Plan or any
other stock option or restricted stock plan of the Company.

     5.   Delivery of Shares; Compliance With Securities Laws, Etc.
          --------------------------------------------------------

          (a)  General.  The Company shall, upon payment of the option price for
               -------
the number of shares purchased and paid for, make prompt delivery of such shares
to the Optionee, provided that if any law or regulation requires the Company to
                 -------- ----
take any action with respect to such shares before the issuance thereof, then
the date of delivery of such shares shall be extended for the period necessary
to complete such action.

          (b)  Compliance With Securities Laws, Etc.  The Company will not be
               ------------------------------------
obligated to deliver any shares of Common Stock pursuant to the Plan or to
remove restriction from shares previously delivered under the Plan (I) until all
conditions of the option have been satisfied or removed, (ii) until, in the
opinion of the Company's counsel, all applicable federal and state laws and
regulation have been complied with, (iii) if the outstanding Stock is at the
time listed on any stock exchange, until the shares to be delivered have been
listed or authorized to be listed on such exchange upon official notice of
issuance, and (iv) until all other legal matters in connection with the issuance
and delivery of such shares have been approved by the Company's counsel.

     6.   Nontransferability of Option.  This option is personal and no rights
          ----------------------------
granted hereunder may be transferred, assigned, pledged or hypothecated in any
way (whether by operation of law or otherwise) nor shall any such rights be
subject to execution, attachment or similar process.  Upon any attempt to
transfer, assign, pledge, hypothecate or otherwise dispose of this option or of
such rights contrary to the provisions hereof, or upon the levy of any
attachment or similar process upon this option or such rights, this option and
such rights shall, at the election of the Company, become null and void.

     7.   Proxy.  The Optionee hereby appoints Banyan Worldwide, a Massachusetts
          -----
corporation, and/or its designee(s) ("Banyan"), as the Optionee's attorney-in-
fact and proxy, with full power of substitution, for and in the Optionee's name,
to vote, express consent or disapproval, or otherwise act in

                                      -3-
<PAGE>

such manner (including pursuant to written consent) and upon such matters as
Banyan or its designee(s), proxy or substitute(s) shall, in its or their sole
discretion, deem proper with respect to any and all of the shares issued upon
any exercise of this option or issued in respect to such shares as a stock
dividend, stock split or otherwise (collectively, for purposes of Sections 7, 8
and 9 hereof, the "Shares"). The proxy granted hereby shall be irrevocable and
may be exercised at any meeting or in respect of any written consent of
stockholders. This proxy is coupled with an interest sufficient in law to
support such proxy. This proxy shall remain in full force and effect and be
enforceable against any donee, transferee or assignee of the stock. In addition
to any other applicable limitations pursuant to the terms of this option, the
Optionee agrees not to sell, assign, transfer, loan, tender, pledge,
hypothecate, exchange, encumber or otherwise dispose of, or issue an option or
call with respect to, any of the Shares, or impair such Shares, in each case
unless, and as a condition precedent thereto, the transferee of such Shares
executes and delivers to Banyan an agreement to be bound by the terms of this
Section 7. Any purported transfer in violation of this Section 7 shall be null
and void and shall not be recognized by the Company or reflected on the stock
records of the Company. The Optionee shall cause the Company to require any
certificates representing any and all Shares issued upon any exercise of this
option to bear a legend referencing the restrictions on transfer set for in this
Section 7, which legend shall be subject to the approval of Banyan.
Notwithstanding anything to the contrary in the foregoing, the provisions of,
including, without limitation, the proxy appointed by, this Section 7 shall
terminate upon the closing of the Company's initial public offering,
underwritten by a nationally recognized underwriter, pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the
"Securities Act").

     8.   Repurchase of Shares Upon Termination of Employment.  The following
          ---------------------------------------------------
repurchase provisions shall apply to any and all Shares;

          (a)  Repurchase Rights.  If the Optionee for any reason whatsoever
               -----------------
(including without limitation death, disability, or voluntary or involuntary
termination) ceases to be employed by the Company prior to the date specified in
Section 8(d) below for the expiration of these restrictions, then during the 90-
day period following such termination the Company may elect, by written notice
delivered to the Optionee, to repurchase all or any portion of the Shares, at a
price per share equal to the fair market value of such Shares as of the close of
business on the date of termination of the Optionee's employment.  Such fair
market value shall be determined by mutual agreement of the Company and the
Optionee.  Failing such agreement between the Optionee and the Company within 30
days of the date of the Company's notice electing to repurchase such Shares, the
fair market value of such Shares shall be determined by three appraisers, one
designated within five days after the termination of said 30-day period by the
Optionee or his or her legal representatives (which appraiser shall not be the
Optionee or his or her legal representative), one within said period of five
days by the Company (which appraiser shall not be an officer, director or
employee of the Company) and the third within five days after said appointment
last occurring by the two appraisers so chosen.  Successor appraisers, if any
shall be required, shall be appointed, within a reasonable time, as nearly as
may be in the manner provided as to the related original appointment.  No
appointment shall be deemed as having been accomplished unless such appraiser
shall have accepted in writing his appointment as such within the time limited
for his appointment.  Notice of each appointment of an appraiser shall be given
promptly to the other parties in interest.  Any expenses relating to the
appointment and service of an appraiser shall be paid by the party appointing
such appraiser or, in the case of the appraiser appointed by the appraisers
chosen by the Company and the Optionee, shall be paid by the Company.  Said
appraisers shall proceed promptly to determine the fair market value of said
Share or Shares by agreement of any two of the appraisers, which shall be
conclusive upon all parties in interest in such Shares.  Promptly following such
determination, the appraisers shall mail or deliver such notice of such
determination to the Optionee and the Company.

                                      -4-
<PAGE>

          (b)  Repurchase Procedure. Upon notice from the Company of exercise of
               --------------------
its rights under this Section 8 and determination of the purchase price for the
Shares so repurchased, the Optionee shall transfer the Shares or appropriate
part thereof to the Company against payment by the Company of the purchase price
therefor.  If upon the expiration of the 90-day period following the Optionee's
termination of employment the Company shall have failed to elect to repurchase
all of the Shares, the repurchase rights with respect to the Shares not so
elected to be repurchased imposed by this Section 8 shall terminate, and the
Optionee or his or her legal representatives may thereafter transfer such
Shares.  The Optionee or his or her legal representatives may in no event
transfer any Shares prior thereto, other than to the Company.

          (C)  Failure of Optionee to Comply.  If the Optionee fails to comply
               -----------------------------
with any of the provisions of this Section 8, the Company, at its option and in
addition to its other remedies, may suspend the rights of the Optionee to vote
and to receive dividends on the Shares, or may refuse to register on its books
any transfer or change in the ownership of the Shares or in the right to vote
thereon, until the provisions of this Section 8 are complied with to the
satisfaction of the Company.

          (d)  Expiration.  The restriction contained in this Section 8 shall
               ----------
expire upon the closing of the Company's initial public offering, underwritten
by a nationally recognized underwriter, pursuant to an effective registration
statement under the Securities Act of 1933, as amended (the "Securities Act")
(such expiration date shall be referred to herein as the "Expiration Date").

          (e)  Safekeeping.  The Optionee acknowledges that the Company may, in
               -----------
its discretion, retain for safekeeping stock certificates representing all
Shares purchased hereunder by the Optionee.  The Optionee further acknowledges
that the Company may, to insure that the Optionee complies with the restriction
of this Section 8, continue to retain such stock certificates until the earlier
of the Expiration Date or the date of expiration of these repurchase rights
under Section 8(b) above.  At the time of any exercise of this option, in whole
or in part, the Optionee shall execute such further agreement as the Company may
require to implement the foregoing.

     9.   Right of First Refusal.
          ----------------------

          (a)  General.  The Optionee shall not sell, assign, pledge, or in any
               -------
manner transfer any of the Shares or any right or interest therein, whether
voluntarily or by operation of law, or by gift or otherwise, except by a
transfer which meets the requirements of the provisions of this Section 9.

          (b)  Restrictions on Transfer. If at any time or from time to time the
               ------------------------
Optionee intends to sell or transfer any Shares to a third party, the Optionee
shall provide notice thereof to the Company prior to such transfer (which in the
case of a sale shall include a bona fide purchase agreement with a viable
purchaser).  The Company shall have an option for 30 days following the date of
receipt of the Optionee's notice to purchase such Shares on the terms upon which
the Shares were to be purchased by or transferred to the third party by the
Optionee.  If the Company does not exercise its right of first refusal under
this Section 9(b) with respect to such proposed sale or transfer within such 30-
day period, the Optionee shall be free to sell or transfer such Shares to the
third party identified in the Optionee's notice for a period of 45 days after
the expiration of the 30-day period following the date of receipt of the
Optionee's notice.  Such sale or transfer must be on terms no more favorable to
the recipient than those set forth in the Optionee's notice.  In no event may
Shares be sold or transferred to any then-current competitor of the Company.
Any transfer or sale of Shares by the Optionee will be conditional upon the
recipient acknowledging in writing the option set forth in this Section 9(b) and
the other restrictions to which the Shares are subject.

                                      -5-
<PAGE>

          (C)  Failure of Optionee to Comply.  If the Optionee's notice in
               -----------------------------
respect of any Shares is not received by the Company as provided in Section 9(b)
above, or if the Optionee fails to comply with the provisions of Section 9(b)
above in respect of any such Shares in any other regard, the Company, at its
option and in addition to its other remedies, may suspend the rights to vote or
to receive dividends on said Shares, or may refuse to register on its books any
transfer or change in ownership of said Shares or in the right to vote thereon,
until the provisions of Section 9(b) are complied with to the satisfaction of
the Company; and if the required Optionee's notice is not received by the
Company after written demand by the Company, the Company may also independently
proceed as though a proper Optionee's notice has been received at the expiration
of ten days after mailing such demand, and, if the Company exercises its rights
under Section 9(b) with respect to said Shares or any of them, the Shares
specified shall be transferred accordingly.

          (d)  Expiration.  The Company's right of first refusal contained in
               ----------
this Section 9 with respect to any sale or transfer of Shares shall expire upon
the Expiration Date.

     10.  No Special Employment Rights.  Nothing contained in the Plan or this
          ----------------------------
option shall be construed or deemed by any person under any circumstances to
bind the Company to continue the employment of the Optionee for the period
within which this option may be exercised.

     11.  Rights as a Shareholder.  The Optionee shall have no rights as a
          -----------------------
shareholder with respect to any shares which may be purchased by exercise of
this option (including, without limitation, any rights to receive dividends or
non-cash distributions with respect to such shares) unless and until a
certificate representing such shares is duly issued and delivered to the
Optionee.  No adjustment shall be made for dividends or other rights for which
the record date is prior to the date such stock certificate is issued.

     12.  Adjustment Provisions.
          ---------------------

          (a)  General.  In the event of a consolidation, merger or other
               -------
reorganization in which all of the outstanding shares of Common Stock are
exchanged for securities, cash or other property of any other corporation or
business entity (an "Acquisition") or in the event of a liquidation of the
Company, the Board of Directors of the Company or the board of directors of any
corporation assuming the obligations of the Company, may, in its discretion,
take any one or more of the following actions as to this option:  (I) provide
that this option shall be assumed, or a substantially equivalent option shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof) on such terms as the Board determines to be appropriate, (ii) upon
written notice to the Optionee, provide that if unexercised, this option will
terminate immediately prior to the consummation of such transaction unless
exercised by the Optionee within a specified period following the date of such
notice, (iii) in the event of an Acquisition under the terms of which holders of
the Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the Acquisition (the "Acquisition Price"),
make or provide for a cash payment to the Optionee equal to the difference
between (A) the Acquisition Price times the number of shares of Common Stock
subject to outstanding options (to the extent then exercisable at prices not in
excess of the Acquisition Price) and (B) the aggregate exercise price of all
such outstanding options in exchange for the termination of such options, and
(iv) provide that all or any outstanding options shall become exercisable or
realizable in full prior to the effective date of such Acquisition.

          (b)  Board Authority to Make Adjustments.  Any adjustments under this
               -----------------------------------
Section 12 will be made by the Board of Directors, whose determination as to
what adjustments, if any, will be made

                                      -6-
<PAGE>

and the extent thereof will be final, binding and conclusive. No fractional
shares will be issued pursuant to this option on account of any such
adjustments.

     13.  Withholding Taxes.  The Company's obligation to deliver shares upon
          -----------------
the exercise of this option shall be subject to the Optionee's satisfaction of
all applicable federal, state and local income and employment tax withholding
requirements.  The Optionee shall pay to the Company, or make provision
satisfactory to the Board for payment of, any taxes required by law to be
withheld in respect of options under the Plan no later than the date of the
event creating the tax liability.  In the Board's discretion, and subject to
such conditions as the Board may establish, such tax obligations may be paid in
whole or in part in shares of Common Stock, including shares retained from the
option creating the tax obligation, valued at their fair market value.  The
Company may, to the extent permitted by law, deduct any such tax obligations
from any payment of any kind otherwise due to the Optionees.

     14.  Limitations on Disposition of Incentive Stock Option Shares.  It is
          -----------------------------------------------------------
understood and intended that this option shall qualify as an "incentive stock
option" as defined in Section 422 of the Code.  Accordingly, the Optionee
understands that in order to obtain the benefits of an incentive stock option
under Section 421 of the Code, no sale or other disposition may be made of any
shares acquired upon exercise of the option within one year after the day of the
transfer of such shares to him, nor within two years after the grant of the
option.  If the Optionee intends to dispose, or does dispose (whether by sale,
exchange, gift, transfer or otherwise), of any such shares within said periods,
he or she will notify the Company in writing within ten days after such
disposition.

     15.  Investment Representations; Legends.
          -----------------------------------

          (a)  Representations.  The Optionee represents, warrants and covenants
               ---------------
that:

               (i)   Any shares purchased upon exercise of this option shall be
               acquired for the Optionee's account for investment only and not
               with a view to, or for sale in connection with, any distribution
               of the shares in violation of the Securities Act or any rule or
               regulation under the Securities Act.

               (ii)  The Optionee has had such opportunity as he or she has
               deemed adequate to obtain from representatives of the Company
               such information as is necessary to permit the Optionee to
               evaluate the merits and risks of his or her investment in the
               Company.

               (iii) The Optionee is able to bear the economic risk of holding
               shares acquired pursuant to the exercise of this option for an
               indefinite period.

               (iv)  The Optionee understands that (A) the shares acquired
               pursuant to the exercise of this option will not be registered
               under the Securities Act and are "restricted securities" within
               the meaning of Rule 144 under the Securities Act; (B) such shares
               cannot be sold, transferred or otherwise disposed of unless they
               are subsequently registered under the Securities Act or an
               exemption from registration is then available; (C) in any event,
               an exemption from registration under Rule 144 or otherwise under
               the Securities Act may not be available for at least two years
               and even then will not be available unless a public market then
               exists for the Common Stock, adequate information concerning the
               Company is

                                      -7-
<PAGE>

               then available to the public and other terms and conditions of
               Rule 144 are complied with; and (D) there is now no registration
               statement on file with the Securities and Exchange Commission
               with respect to any stock of the Company and the Company has no
               obligation or current intention to register any shares acquired
               pursuant to the exercise of this option under the Securities Act.

               (v)   The Optionee agrees that, if the Company offers for the
               first time any of its Common Stock for sale pursuant to a
               registration statement under the Securities Act, the Optionee
               will not, without the prior written consent of the Company,
               publicly offer, sell, contract to sell or otherwise dispose of,
               directly or indirectly, any shares purchased upon exercise of
               this option for a period of 180 days after the effective date of
               such registration statement.

By making payment upon exercise of this option, the Optionee shall be deemed to
have reaffirmed, as of the date of such payment, the representations made in
this Section 15.

          (b)  Legends on Stock Certificates.  All stock certificates
               -----------------------------
representing shares of Common Stock issued to the Optionee upon exercise of this
option shall have affixed thereto legends substantially in the following forms,
in addition to any other legends required by applicable state law:


          "The shares of stock represented by this certificate have not been
          registered under the Securities Act of 1933 and may not be
          transferred, sold or otherwise disposed of in the absence of an
          effective registration statement with respect to the shares evidenced
          by this certificate, filed and made effective under the Securities Act
          of 1933, or an opinion of counsel satisfactory to the Company to the
          effect that registration under such Act is not required."

          "The shares of stock represented by this certificate are subject to
          certain restrictions on transfer and repurchase rights contained in an
          Option Agreement, a copy of which will be furnished upon request by
          the issuer."

To ensure compliance with the terms of this agreement, the Company may issue to
its transfer agent appropriate stop transfer instructions with respect to the
Shares.

     16.  Miscellaneous.
          -------------

          (a)  The Board may amend, modify or terminate any outstanding option,
including substituting therefor another option of the same or a different type,

consent to such action shall be required unless the Board determines that the
action, taking into account any related action, would not materially and
adversely affect the Optionee.  The Board may at any time accelerate the time at
which all or any part of an Option may be exercised.

          (b)  All notices under this option shall be mailed or delivered by
hand to the parties at their respective addresses set forth beneath their names

<PAGE>

           Notwithstanding anything to the contrary in this option or in the
Plan, this option will vest as to 100% of the then-unvested shares upon the
occurrence of a Change of Control (as defined herein). For the purposes of this
option, a "Change of Control" shall mean an event or occurrence set forth in any
one or more of clauses (i) through (iv) below (including an event or occurrence
that constitutes a Change in Control under one of such subsections but is
specifically exempted from another such subsection):

     (i)   the acquisition by an individual, entity or group (within the meaning
     of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as
     amended (the "Exchange Act")) (a "Person"), other than Banyan Worldwide or
     CBS Corporation, of beneficial ownership of any capital stock of the
     Company if, after such acquisition, such Person beneficially owns (within
     the meaning of Rule 13d-3 promulgated under the Exchange Act) 20% or more
     of either (A) the then-outstanding shares of common stock of the Company
     (the "Outstanding Company Common Stock") or (B) the combined voting power
     of the then-outstanding securities of the Company entitled to vote
     generally in the election of directors (the "Outstanding Company Voting
     Securities"); provided, however, that for purposes of this clause (i), the
                   --------
     following acquisitions shall not constitute a Change in Control: (I) any
     acquisition directly from the Company (excluding an acquisition pursuant to
     the exercise, conversion or exchange of any security exercisable for,
     convertible into or exchangeable for common stock or voting securities of
     the Company, unless the Person exercising, converting or exchanging such
     security acquired such security directly from the Company or an underwriter
     or agent of the Company), (II) any acquisition by the Company, (III) any
     acquisition by any employee benefit plan (or related trust) sponsored or
     maintained by the Company or any corporation controlled by the Company, or
     (IV) any acquisition by any corporation pursuant to a transaction which
     complies with clauses (A) and (B) of clause (iii) of this Section 3(a); or

     (ii)  such time as the Continuing Directors (as defined below) do not
     constitute a majority of the Board (or, if applicable, the Board of
     Directors of a successor corporation to the Company), where the term
     "Continuing Director" means at any date a member of the  Board (A) who was
     a member of the Board on the date of the execution of this Agreement or (B)
     who was nominated or elected subsequent to such date by at least a majority
     of the directors who were Continuing Directors at the time of such
     nomination or election or whose election to the Board was recommended or
     endorsed by at least a majority of the directors who were Continuing
     Directors at the time of such nomination or election; provided, however,
                                                           --------  -------
     that there shall be excluded from this clause (B) any individual whose
     initial assumption of office occurred as a result of an actual or
     threatened election contest with respect to the election or removal of
     directors or other actual or threatened solicitation of proxies or
     consents, by or on behalf of a person other than the Board; or

     (iii) the consummation of a merger, consolidation, reorganization,
     recapitalization or statutory share exchange involving the Company or a
     sale or other disposition of all or substantially all of the assets of the
     Company (a "Business Combination"), unless, immediately following such
     Business Combination, each of the following two conditions is satisfied:
     (A) all or substantially all of the individuals and entities who were the
<PAGE>

     beneficial owners of the Outstanding Company Common Stock and Outstanding
     Company Voting Securities immediately prior to such Business Combination
     beneficially own, directly or indirectly, more than 50% of the then-
     outstanding shares of common stock and the combined voting power of the
     then-outstanding securities entitled to vote generally in the election of
     directors, respectively, of the resulting or acquiring corporation in such
     Business Combination (which shall include, without limitation, a
     corporation which as a result of such transaction owns the Company or
     substantially all of the Company's assets either directly or through one or
     more subsidiaries) (such resulting or acquiring corporation is referred to
     herein as the "Acquiring Corporation") in substantially the same
     proportions as their ownership, immediately prior to such Business
     Combination, of the Outstanding Company Common Stock and Outstanding
     Company Voting Securities, respectively; and (B) no Person (excluding the
     Acquiring Corporation or any employee benefit plan (or related trust)
     maintained or sponsored by the Company or by the Acquiring Corporation)
     beneficially owns, directly or indirectly, 20% or more of the then
     outstanding shares of common stock of the Acquiring Corporation, or of the
     combined voting power of the then-outstanding securities of such
     corporation entitled to vote generally in the election of directors (except
     to the extent that such ownership existed prior to the Business
     Combination); or

     (iv) approval by the stockholders of the Company of a complete liquidation
          or dissolution of the Company.

          (b) Exercise Procedure.  Subject to the conditions set forth in this
              ------------------
Agreement, this option shall be exercised by the Optionee's delivery of written
notice of exercise to the Treasurer of the Company, specifying the number of
shares to be purchased and the purchase price to be paid therefor and
accompanied by payment in full in accordance with Section 4. Such exercise shall
be effective upon receipt by the Treasurer of the Company of such written notice
together with the required payment. The Optionee may purchase less than the
number of shares covered hereby, provided that no partial exercise of this
option may be for any fractional share or for fewer than ten whole shares.

          (c) Continuous Relationship with the Company Required.  This option
              -------------------------------------------------
may not be exercised unless the Optionee, at the time he or she exercises this
option, is, and has been at all times since the date of grant of this option, an
employee of either the Company or Banyan Worldwide, officer or director of, or
consultant or advisor to, the Company (an "Eligible Optionee").

          (d) Termination of Employment.  If the Optionee ceases to be employed
              -------------------------
by the Company for any reason (including without limitation death, disability,
or voluntary or involuntary termination), then the right to exercise this option
shall terminate 30 days after such cessation.

          (e) Early Exercise Alternative.  Notwithstanding the exercisability
              --------------------------
schedule set forth in paragraph (a), the Optionee may elect to exercise this
option as to the unvested shares (in addition to the vested shares) if
simultaneously with such exercise the Optionee enters into a Stock Restriction
Agreement with the Company in the form attached hereto as Exhibit A
                                                          ---------
(the "Stock Restriction Agreement"). The Stock Restriction Agreement provides
that the unvested shares shall be subject to a right of repurchase (the
"Purchase Option") in favor of the Company at the $8.50 exercise price (as
adjusted pursuant to the terms hereof) in the event that the Optionee
ceases to be employed by the Company.

     4.   Payment of Purchase Price.
          -------------------------
<PAGE>

          (a) Method of Payment.  Payment of the purchase price for shares
              -----------------
purchased upon exercise of this option shall be made by delivery of cash or a
check in an amount equal to the exercise price of such option or, with the prior
consent of the Company (which may be withheld in its sole discretion), by (A)
delivery of shares of Common Stock owned by the Optionee for at least six
months, valued at their fair market value, as determined in (b) below, (B)
delivery of a promissory note of the Optionee to the Company on terms determined
by the Board, (C) delivery of an irrevocable undertaking by a broker to deliver
promptly to the Company sufficient funds to pay the exercise price or delivery
of irrevocable instructions to a broker to deliver promptly to the Company cash
or a check sufficient to pay the exercise price, (D) payment of such other
lawful consideration as the Board may determine, or (E) any combination of the
foregoing.

          (b) Valuation of Shares or Other Non-Cash Consideration Tendered in
              ---------------------------------------------------------------
Payment of Purchase Price.  For the purposes hereof, the fair market value of
- -------------------------
any share of the Company's Common Stock or other non-cash consideration which
may be delivered to the Company in exercise of this option shall be determined
in good faith by the Board of Directors of the Company.

          (c) Delivery of Shares Tendered in Payment of Purchase Price.  If the
              --------------------------------------------------------
Optionee exercises this option by delivery of shares of Common Stock of the
Company, the certificate or certificates representing the shares of Common Stock
of the Company to be delivered shall be duly executed in blank by the Optionee
or shall be accompanied by a stock power duly executed in blank suitable for
purposes of transferring such shares to the Company.  Fractional shares of
Common Stock of the Company will not be accepted in payment of the purchase
price of shares acquired upon exercise of this option.

          (d) Restrictions on Use of Option Stock.  Notwithstanding the
              -----------------------------------
foregoing, no shares of Common Stock of the Company may be tendered in payment
of the purchase price of shares purchased upon exercise of this option if the
shares to be so tendered were acquired within six (6) months before the date of
such tender, through the exercise of an option granted under the Plan or any
other stock option or restricted stock plan of the Company.

     5.   Delivery of Shares; Compliance With Securities Laws, Etc.
          --------------------------------------------------------

          (a) General.  The Company shall, upon payment of the option price for
              -------
the number of shares purchased and paid for, make prompt delivery of such shares
to the Optionee, provided that if any law or regulation requires the Company to
take any action with respect to such shares before the issuance thereof, then
the date of delivery of such shares shall be extended for the period necessary
to complete such action.

          (b) Compliance With Securities Laws, Etc.  The Company will not be
              -------------------------------------
obligated to deliver any shares of Common Stock pursuant to the Plan or to
remove restriction from shares previously delivered under the Plan (i) until all
conditions of the option have been satisfied or removed, (ii) until, in the
opinion of the Company's counsel, all applicable federal and state laws and
regulation have been complied with, (iii) if the outstanding Stock is at the
time listed on any stock exchange, until the shares to be delivered have been
listed or authorized
<PAGE>

to be listed on such exchange upon official notice of issuance, and (iv) until
all other legal matters in connection with the issuance and delivery of such
shares have been approved by the Company's counsel.

     6.   Nontransferability of Option.  This option is personal and no rights
          ----------------------------
granted hereunder may be transferred, assigned, pledged or hypothecated in any
way (whether by operation of law or otherwise) nor shall any such rights be
subject to execution, attachment or similar process.  Upon any attempt to
transfer, assign, pledge, hypothecate or otherwise dispose of this option or of
such rights contrary to the provisions hereof, or upon the levy of any
attachment or similar process upon this option or such rights, this option and
such rights shall, at the election of the Company, become null and void.

     7.   Proxy.  The Optionee hereby appoints Banyan Worldwide, a Massachusetts
          -----
corporation, and/or its designee(s) ("Banyan"), as the Optionee's attorney-in-
fact and proxy, with full power of substitution, for and in the Optionee's name,
to vote, express consent or disapproval, or otherwise act in such manner
(including pursuant to written consent) and upon such matters as Banyan or its
designee(s), proxy or substitute(s) shall, in its or their sole discretion, deem
proper with respect to any and all of the shares issued upon any exercise of
this option or issued in respect to such shares as a stock dividend, stock split
or otherwise (collectively, for purposes of Sections 7, 8 and 9 hereof, the
"Shares").  The proxy granted hereby shall be irrevocable and may be exercised
at any meeting or in respect of any written consent of stockholders.  This proxy
is coupled with an interest sufficient in law to support such proxy.  This proxy
shall remain in full force and effect and be enforceable against any donee,
transferee or assignee of the stock.  In addition to any other applicable
limitations pursuant to the terms of this option, the Optionee agrees not to
sell, assign, transfer, loan, tender, pledge, hypothecate, exchange, encumber or
otherwise dispose of, or issue an option or call with respect to, any of the
Shares, or impair such Shares, in each case unless, and as a condition precedent
thereto, the transferee of such Shares executes and delivers to Banyan an
agreement to be bound by the terms of this Section 7.  Any purported transfer in
violation of this Section 7 shall be null and void and shall not be recognized
by the Company or reflected on the stock records of the Company.  The Optionee
shall cause the Company to require any certificates representing any and all
Shares issued upon any exercise of this option to bear a legend referencing the
restrictions on transfer set for in this Section 7, which legend shall be
subject to the approval of Banyan.  Notwithstanding anything to the contrary in
the foregoing, the provisions of, including, without limitation, the proxy
appointed by, this Section 7 shall terminate upon the closing of the Company's
initial public offering, underwritten by a nationally recognized underwriter,
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "Securities Act").

     8.   Repurchase of Shares Upon Termination of Employment.  The following
          ---------------------------------------------------
repurchase provisions shall apply to any and all Shares;

          (a) Repurchase Rights.  If the Optionee for any reason whatsoever
              -----------------
(including without limitation death, disability, or voluntary or involuntary
termination) ceases to be employed by the Company or Banyan Worldwide, or
providing services on behalf of the Company or Banyan Worldwide, prior to the
date specified in Section 8(d) below for the
<PAGE>

expiration of these restrictions, then during the 90-day period following such
termination the Company may elect, by written notice delivered to the Optionee,
to repurchase all or any portion of the Shares, at a price per share equal to
the fair market value of such Shares as of the close of business on the date of
termination of the Optionee's employment. Such fair market value shall be
determined by mutual agreement of the Company and the Optionee. Failing such
agreement between the Optionee and the Company within 30 days of the date of the
Company's notice electing to repurchase such Shares, the fair market value of
such Shares shall be determined by three appraisers, one designated within five
days after the termination of said 30-day period by the Optionee or his or her
legal representatives (which appraiser shall not be the Optionee or his or her
legal representative), one within said period of five days by the Company (which
appraiser shall not be an officer, director or employee of the Company) and the
third within five days after said appointment last occurring by the two
appraisers so chosen. Successor appraisers, if any shall be required, shall be
appointed, within a reasonable time, as nearly as may be in the manner provided
as to the related original appointment. No appointment shall be deemed as having
been accomplished unless such appraiser shall have accepted in writing his
appointment as such within the time limited for his appointment. Notice of each
appointment of an appraiser shall be given promptly to the other parties in
interest. Any expenses relating to the appointment and service of an appraiser
shall be paid by the party appointing such appraiser or, in the case of the
appraiser appointed by the appraisers chosen by the Company and the Optionee,
shall be paid by the Company. Said appraisers shall proceed promptly to
determine the fair market value of said Share or Shares by agreement of any two
of the appraisers, which shall be conclusive upon all parties in interest in
such Shares. Promptly following such determination, the appraisers shall mail or
deliver such notice of such determination to the Optionee and the Company.

          (b) Repurchase Procedure.  Upon notice from the Company of exercise of
              --------------------
its rights under this Section 8 and determination of the purchase price for the
Shares so repurchased, the Optionee shall transfer the Shares or appropriate
part thereof to the Company against payment by the Company of the purchase price
therefor.  If upon the expiration of the 90-day period following the Optionee's
termination of employment the Company shall have failed to elect to repurchase
all of the Shares, the repurchase rights with respect to the Shares not so
elected to be repurchased imposed by this Section 8 shall terminate, and the
Optionee or his or her legal representatives may thereafter transfer such
Shares.  The Optionee or his or her legal representatives may in no event
transfer any Shares prior thereto, other than to the Company.

          (c) Failure of Optionee to Comply.  If the Optionee fails to comply
              -----------------------------
with any of the provisions of this Section 8, the Company, at its option and in
addition to its other remedies, may suspend the rights of the Optionee to vote
and to receive dividends on the Shares, or may refuse to register on its books
any transfer or change in the ownership of the Shares or in the right to vote
thereon, until the provisions of this Section 8 are complied with to the
satisfaction of the Company.

          (d) Expiration.  The restriction contained in this Section 8 shall
              ----------
expire upon the closing of the Company's initial public offering, underwritten
by a nationally recognized underwriter, pursuant to an effective registration
statement under the Securities Act (such expiration date shall be referred to
herein as the "Expiration Date").
<PAGE>

          (e) Safekeeping.  The Optionee acknowledges that the Company may, in
              -----------
its discretion, retain for safekeeping stock certificates representing all
Shares purchased hereunder by the Optionee.  The Optionee further acknowledges
that the Company may, to insure that the Optionee complies with the restriction
of this Section 8, continue to retain such stock certificates until the earlier
of the Expiration Date or the date of expiration of these repurchase rights
under Section 8(b) above.  At the time of any exercise of this option, in whole
or in part, the Optionee shall execute such further agreement as the Company may
require to implement the foregoing.

     9.   Right of First Refusal.
          ----------------------

          (a) General.  The Optionee shall not sell, assign, pledge, or in any
              -------
manner transfer any of the Shares or any right or interest therein, whether
voluntarily or by operation of law, or by gift or otherwise, except by a
transfer which meets the requirements of the provisions of this Section 9.

          (b) Restrictions on Transfer.  If at any time or from time to time the
              ------------------------
Optionee intends to sell or transfer any Shares to a third party, the Optionee
shall provide notice thereof to the Company prior to such transfer (which in the
case of a sale shall include a bona fide purchase agreement with a viable
purchaser).  The Company shall have an option for 30 days following the date of
receipt of the Optionee's notice to purchase such Shares on the terms upon which
the Shares were to be purchased by or transferred to the third party by the
Optionee.  If the Company does not exercise its right of first refusal under
this Section 9(b) with respect to such proposed sale or transfer within such 30-
day period, the Optionee shall be free to sell or transfer such Shares to the
third party identified in the Optionee's notice for a period of 45 days after
the expiration of the 30-day period following the date of receipt of the
Optionee's notice.  Such sale or transfer must be on terms no more favorable to
the recipient than those set forth in the Optionee's notice.  In no event may
Shares be sold or transferred to any then-current competitor of the Company.
Any transfer or sale of Shares by the Optionee will be conditional upon the
recipient acknowledging in writing the option set forth in this Section 9(b) and
the other restrictions to which the Shares are subject.

          (c) Failure of Optionee to Comply.  If the Optionee's notice in
              -----------------------------
respect of any Shares is not received by the Company as provided in Section 9(b)
above, or if the Optionee fails to comply with the provisions of Section 9(b)
above in respect of any such Shares in any other regard, the Company, at its
option and in addition to its other remedies, may suspend the rights to vote or
to receive dividends on said Shares, or may refuse to register on its books any
transfer or change in ownership of said Shares or in the right to vote thereon,
until the provisions of Section 9(b) are complied with to the satisfaction of
the Company; and if the required Optionee's notice is not received by the
Company after written demand by the Company, the Company may also independently
proceed as though a proper Optionee's notice has been received at the expiration
of ten days after mailing such demand, and, if the Company exercises its rights
under Section 9(b) with respect to said Shares or any of them, the Shares
specified shall be transferred accordingly.

          (d) Expiration.  The Company's right of first refusal contained in
              ----------
this Section 9 with respect to any sale or transfer of Shares shall expire upon
the Expiration Date.
<PAGE>

     10.  No Special Employment Rights.  Nothing contained in the Plan or this
          ----------------------------
option shall be construed or deemed by any person under any circumstances to
bind the Company to continue the employment of the Optionee for the period
within which this option may be exercised.

     11.  Rights as a Shareholder.  The Optionee shall have no rights as a
          -----------------------
shareholder with respect to any shares which may be purchased by exercise of
this option (including, without limitation, any rights to receive dividends or
non-cash distributions with respect to such shares) unless and until a
certificate representing such shares is duly issued and delivered to the
Optionee.  No adjustment shall be made for dividends or other rights for which
the record date is prior to the date such stock certificate is issued.

     12.  Adjustment Provisions.
          ---------------------

          (a) General.  In the event of a consolidation, merger or other
              -------
reorganization in which all of the outstanding shares of Common Stock are
exchanged for securities, cash or other property of any other corporation or
business entity (an "Acquisition") or in the event of a liquidation of the
Company, the Board of Directors of the Company or the board of directors of any
corporation assuming the obligations of the Company, may, in its discretion,
take any one or more of the following actions as to this option:  (i) provide
that this option shall be assumed, or a substantially equivalent option shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof) on such terms as the Board determines to be appropriate, (ii) upon
written notice to the Optionee, provide that if unexercised, this option will
terminate immediately prior to the consummation of such transaction unless
exercised by the Optionee within a specified period following the date of such
notice, (iii) in the event of an Acquisition under the terms of which holders of
the Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the Acquisition (the "Acquisition Price"),
make or provide for a cash payment to the Optionee equal to the difference
between (A) the Acquisition Price times the number of shares of Common Stock
subject to outstanding options (to the extent then exercisable at prices not in
excess of the Acquisition Price) and (B) the aggregate exercise price of all
such outstanding options in exchange for the termination of such options, and
(iv) provide that all or any outstanding options shall become exercisable or
realizable in full prior to the effective date of such Acquisition.

          (b) Board Authority to Make Adjustments.  Any adjustments under this
              -----------------------------------
Section 12 will be made by the Board of Directors, whose determination as to
what adjustments, if any, will be made and the extent thereof will be final,
binding and conclusive.  No fractional shares will be issued pursuant to this
option on account of any such adjustments.

     13.  Withholding Taxes.  The Company's obligation to deliver shares upon
          -----------------
the exercise of this option shall be subject to the Optionee's satisfaction of
all applicable federal, state and local income and employment tax withholding
requirements.

     14.  Investment Representations; Legends.
          -----------------------------------
<PAGE>

          (a)   Representations.  The Optionee represents, warrants and
                ---------------
covenants that:

          (i)   Any shares purchased upon exercise of this option shall be
     acquired for the Optionee's account for investment only and not with a view
     to, or for sale in connection with, any distribution of the shares in
     violation of the Securities Act or any rule or regulation under the
     Securities Act.

          (ii)  The Optionee has had such opportunity as he or she has deemed
     adequate to obtain from representatives of the Company such information as
     is necessary to permit the Optionee to evaluate the merits and risks of his
     or her investment in the Company.

          (iii) The Optionee is able to bear the economic risk of holding
     shares acquired pursuant to the exercise of this option for an indefinite
     period.

          (iv)  The Optionee understands that (A) the shares acquired pursuant
     to the exercise of this option will not be registered under the Securities
     Act and are "restricted securities" within the meaning of Rule 144 under
     the Securities Act; (B) such shares cannot be sold, transferred or
     otherwise disposed of unless they are subsequently registered under the
     Securities Act or an exemption from registration is then available; (C) in
     any event, an exemption from registration under Rule 144 or otherwise under
     the Securities Act may not be available for at least two years and even
     then will not be available unless a public market then exists for the
     Common Stock, adequate information concerning the Company is then available
     to the public and other terms and conditions of Rule 144 are complied with;
     and (D) there is now no registration statement on file with the Securities
     and Exchange Commission with respect to any stock of the Company and the
     Company has no obligation or current intention to register any shares
     acquired pursuant to the exercise of this option under the Securities Act.

          (v)   The Optionee agrees that, if the Company offers for the first
     time any of its Common Stock for sale pursuant to a registration statement
     under the Securities Act, the Optionee will not, without the prior written
     consent of the Company, publicly offer, sell, contract to sell or otherwise
     dispose of, directly or indirectly, any shares purchased upon exercise of
     this option for a period of 180 days after the effective date of such
     registration statement.

By making payment upon exercise of this option, the Optionee shall be deemed to
have reaffirmed, as of the date of such payment, the representations made in
this Section 14.

          (b)   Legends on Stock Certificates.  All stock certificates
                -----------------------------
representing shares of Common Stock issued to the Optionee upon exercise of this
option shall have affixed thereto legends substantially in the following forms,
in addition to any other legends required by applicable state law:

     "The shares of stock represented by this certificate have not been
     registered under the Securities Act of 1933 and may not be transferred,
     sold or otherwise disposed of in the absence of an effective registration
     statement with respect to the shares evidenced by this
<PAGE>

     certificate, filed and made effective under the Securities Act of 1933, or
     an opinion of counsel satisfactory to the Company to the effect that
     registration under such Act is not required."

     "The shares of stock represented by this certificate are subject to certain
     restrictions on transfer and repurchase rights contained in an Option
     Agreement, a copy of which will be furnished upon request by the issuer."

To ensure compliance with the terms of this agreement, the Company may issue to
its transfer agent appropriate stop transfer instructions with respect to the
Shares.

     15.  Miscellaneous.
          -------------

          (a) The Board may amend, modify or terminate any outstanding option,
including substituting therefor another option of the same or a different type,
changing the date of exercise or realization, provided that the Optionee's
consent to such action shall be required unless the Board determines that the
action, taking into account any related action, would not materially and
adversely affect the Optionee.  The Board may at any time accelerate the time at
which all or any part of an Option may be exercised.

          (b) All notices under this option shall be mailed or delivered by hand
to the parties at their respective addresses set forth beneath their names below
or at such other address as may be designated in writing by either of the
parties to one another.

          (c) This option shall be governed by and construed in accordance with
the laws of the Commonwealth of Massachusetts.

Notwithstanding anything to the contrary in this option or in the Plan, this

     of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as
     amended (the "Exchange Act")) (a "Person"), other than Banyan Worldwide or

     of either (A) the then-outstanding shares of common stock of the Company
     (the "Outstanding Company Common Stock") or (B) the combined voting power
     of the then-outstanding securities of the Company entitled to vote
     generally in the election of directors (the "Outstanding Company Voting
     Securities"); provided, however, that for purposes of this clause (i), the
                   --------
     following acquisitions shall not constitute a Change in Control: (I) any
     acquisition directly from the Company (excluding an acquisition pursuant to
     the exercise, conversion or exchange of any security exercisable for,
     convertible into or exchangeable for common stock or voting securities of
     the Company, unless the Person exercising, converting or exchanging such
     security acquired such security directly from the Company or an underwriter
     or agent of the Company), (II) any acquisition by the Company, (III) any
     acquisition by any employee benefit plan (or related trust) sponsored or
     maintained by the Company or any corporation controlled by the Company, or
     (IV) any acquisition by any corporation pursuant to a transaction which
     complies with clauses (A) and (B) of clause (iii) of this Section 3(a); or

     (ii)  such time as the Continuing Directors (as defined below) do not
     constitute a majority of the Board (or, if applicable, the Board of
     Directors of a successor corporation to the Company), where the term
     "Continuing Director" means at any date a member of the  Board (A) who was
     a member of the Board on the date of the execution of this Agreement or (B)
     who was nominated or elected subsequent to such date by at least a majority
     of the directors who were Continuing Directors at the time of such
     nomination or election or whose election to the Board was recommended or
     endorsed by at least a majority of the directors who were Continuing
     Directors at the time of such nomination or election; provided, however,
                                                           --------  -------
     that there shall be excluded from this clause (B) any individual whose
     initial assumption of office occurred as a result of an actual or
     threatened election contest with respect to the election or removal of
     directors or other actual or threatened solicitation of proxies or
     consents, by or on behalf of a person other than the Board; or

     (iii) the consummation of a merger, consolidation, reorganization,
     recapitalization or statutory share exchange involving the Company or a
     sale or other disposition of all or substantially all of the assets of the
     Company (a "Business Combination"), unless, immediately following such
     Business Combination, each of the following two conditions is satisfied:
     (A) all or substantially all of the individuals and entities who were the
     beneficial owners of the Outstanding Company Common Stock and Outstanding
     Company Voting Securities immediately prior to such Business Combination
     beneficially own, directly or indirectly, more than 50% of the then-
     outstanding shares of common stock and the combined voting power of the
     then-outstanding securities entitled to vote generally in the election of
     directors, respectively, of the resulting or acquiring
<PAGE>

     corporation in such Business Combination (which shall include, without
     limitation, a corporation which as a result of such transaction owns the
     Company or substantially all of the Company's assets either directly or
     through one or more subsidiaries) (such resulting or acquiring corporation
     is referred to herein as the "Acquiring Corporation") in substantially the
     same proportions as their ownership, immediately prior to such Business
     Combination, of the Outstanding Company Common Stock and Outstanding
     Company Voting Securities, respectively; and (B) no Person (excluding the
     Acquiring Corporation or any employee benefit plan (or related trust)
     maintained or sponsored by the Company or by the Acquiring Corporation)
     beneficially owns, directly or indirectly, 20% or more of the then
     outstanding shares of common stock of the Acquiring Corporation, or of the
     combined voting power of the then-outstanding securities of such
     corporation entitled to vote generally in the election of directors (except
     to the extent that such ownership existed prior to the Business
     Combination); or

     (iv) approval by the stockholders of the Company of a complete liquidation
     or dissolution of the Company.


          (b) Exercise Procedure.  Subject to the conditions set forth in this
              ------------------
Agreement, this option shall be exercised by the Optionee's delivery of written
notice of exercise to the Treasurer of the Company, specifying the number of
shares to be purchased and the purchase price to be paid therefor and
accompanied by payment in full in accordance with Section 4.  Such exercise
shall be effective upon receipt by the Treasurer of the Company of such written
notice together with the required payment.  The Optionee may purchase less than
the number of shares covered hereby, provided that no partial exercise of this
option may be for any fractional share or for fewer than ten whole shares.

          (c) Continuous Relationship with the Company Required.  This option
              -------------------------------------------------
may not be exercised unless the Optionee, at the time he or she exercises this
option, is, and has been at all times since the date of grant of this option, an
employee of either the Company or Banyan Worldwide, officer or director of, or
consultant or advisor to, the Company (an "Eligible Optionee").

          (d) Termination of Employment.  If the Optionee ceases to be employed
              -------------------------
by the Company for any reason (including without limitation death, disability,
or voluntary or involuntary termination), then the right to exercise this option
shall terminate 30 days after such cessation.

          (e) Early Exercise Alternative.  Notwithstanding the exercisability
              --------------------------
schedule set forth in paragraph (a), the Optionee may elect to exercise this
option as to the unvested shares (in addition to the vested shares) if
simultaneously with such exercise the Optionee enters into a Stock Restriction
Agreement with the Company in the form attached hereto as Exhibit A
                                                          ---------
(the "Stock Restriction Agreement"). The Stock Restriction Agreement provides
that the unvested shares shall be subject to a right of repurchase (the
"Purchase Option") in favor of the Company at the $9.00 exercise price (as
adjusted pursuant to the terms hereof) in the event that the Optionee
ceases to be employed by the Company.

     4.   Payment of Purchase Price.
          -------------------------

          (a) Method of Payment.  Payment of the purchase price for shares
              -----------------
purchased upon exercise of this option shall be made by delivery of cash or a
check in an amount equal to the exercise price of such option or, with the prior
consent of the Company (which may be withheld in its sole discretion), by (A)
delivery of shares of Common Stock owned by the Optionee for at least six
months, valued at their fair market value, as determined in (b) below, (B)
delivery of a promissory note of the Optionee to the Company on terms determined
by the
<PAGE>

Board, (C) delivery of an irrevocable undertaking by a broker to deliver
promptly to the Company sufficient funds to pay the exercise price or delivery
of irrevocable instructions to a broker to deliver promptly to the Company cash
or a check sufficient to pay the exercise price, (D) payment of such other
lawful consideration as the Board may determine, or (E) any combination of the
foregoing.

          (b) Valuation of Shares or Other Non-Cash Consideration Tendered in
              ---------------------------------------------------------------
Payment of Purchase Price.  For the purposes hereof, the fair market value of
- -------------------------
any share of the Company's Common Stock or other non-cash consideration which
may be delivered to the Company in exercise of this option shall be determined
in good faith by the Board of Directors of the Company.

          (c) Delivery of Shares Tendered in Payment of Purchase Price.  If the
              --------------------------------------------------------
Optionee exercises this option by delivery of shares of Common Stock of the
Company, the certificate or certificates representing the shares of Common Stock
of the Company to be delivered shall be duly executed in blank by the Optionee
or shall be accompanied by a stock power duly executed in blank suitable for
purposes of transferring such shares to the Company.  Fractional shares of
Common Stock of the Company will not be accepted in payment of the purchase
price of shares acquired upon exercise of this option.

          (d) Restrictions on Use of Option Stock.  Notwithstanding the
              -----------------------------------
foregoing, no shares of Common Stock of the Company may be tendered in payment
of the purchase price of shares purchased upon exercise of this option if the
shares to be so tendered were acquired within six (6) months before the date of
such tender, through the exercise of an option granted under the Plan or any
other stock option or restricted stock plan of the Company.

     5.   Delivery of Shares; Compliance With Securities Laws, Etc.
          --------------------------------------------------------

          (a) General.  The Company shall, upon payment of the option price for
              -------
the number of shares purchased and paid for, make prompt delivery of such shares
to the Optionee, provided that if any law or regulation requires the Company to
take any action with respect to such shares before the issuance thereof, then
the date of delivery of such shares shall be extended for the period necessary
to complete such action.

          (b) Compliance With Securities Laws, Etc.  The Company will not be
              -------------------------------------
obligated to deliver any shares of Common Stock pursuant to the Plan or to
remove restriction from shares previously delivered under the Plan (i) until all
conditions of the option have been satisfied or removed, (ii) until, in the
opinion of the Company's counsel, all applicable federal and state laws and
regulation have been complied with, (iii) if the outstanding Stock is at the
time listed on any stock exchange, until the shares to be delivered have been
listed or authorized to be listed on such exchange upon official notice of
issuance, and (iv) until all other legal matters in connection with the issuance
and delivery of such shares have been approved by the Company's counsel.

     6.   Nontransferability of Option.  This option is personal and no rights
          ----------------------------
granted hereunder may be transferred, assigned, pledged or hypothecated in any
way (whether by
<PAGE>

operation of law or otherwise) nor shall any such rights be subject to
execution, attachment or similar process. Upon any attempt to transfer, assign,
pledge, hypothecate or otherwise dispose of this option or of such rights
contrary to the provisions hereof, or upon the levy of any attachment or similar
process upon this option or such rights, this option and such rights shall, at
the election of the Company, become null and void.

     7.   Proxy.  The Optionee hereby appoints Banyan Worldwide, a Massachusetts
          -----
corporation, and/or its designee(s) ("Banyan"), as the Optionee's attorney-in-
fact and proxy, with full power of substitution, for and in the Optionee's name,
to vote, express consent or disapproval, or otherwise act in such manner
(including pursuant to written consent) and upon such matters as Banyan or its
designee(s), proxy or substitute(s) shall, in its or their sole discretion, deem
proper with respect to any and all of the shares issued upon any exercise of
this option or issued in respect to such shares as a stock dividend, stock split
or otherwise (collectively, for purposes of Sections 7, 8 and 9 hereof, the
"Shares").  The proxy granted hereby shall be irrevocable and may be exercised
at any meeting or in respect of any written consent of stockholders.  This proxy
is coupled with an interest sufficient in law to support such proxy.  This proxy
shall remain in full force and effect and be enforceable against any donee,
transferee or assignee of the stock.  In addition to any other applicable
limitations pursuant to the terms of this option, the Optionee agrees not to
sell, assign, transfer, loan, tender, pledge, hypothecate, exchange, encumber or
otherwise dispose of, or issue an option or call with respect to, any of the
Shares, or impair such Shares, in each case unless, and as a condition precedent
thereto, the transferee of such Shares executes and delivers to Banyan an
agreement to be bound by the terms of this Section 7.  Any purported transfer in
violation of this Section 7 shall be null and void and shall not be recognized
by the Company or reflected on the stock records of the Company.  The Optionee
shall cause the Company to require any certificates representing any and all
Shares issued upon any exercise of this option to bear a legend referencing the
restrictions on transfer set for in this Section 7, which legend shall be
subject to the approval of Banyan.  Notwithstanding anything to the contrary in
the foregoing, the provisions of, including, without limitation, the proxy
appointed by, this Section 7 shall terminate upon the closing of the Company's
initial public offering, underwritten by a nationally recognized underwriter,
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "Securities Act").

     8.   Repurchase of Shares Upon Termination of Employment.  The following
          ---------------------------------------------------
repurchase provisions shall apply to any and all Shares;

          (a) Repurchase Rights.  If the Optionee for any reason whatsoever
              -----------------
(including without limitation death, disability, or voluntary or involuntary
termination) ceases to be employed by the Company or Banyan Worldwide, or
providing services on behalf of the Company or Banyan Worldwide, prior to the
date specified in Section 8(d) below for the expiration of these restrictions,
then during the 90-day period following such termination the Company may elect,
by written notice delivered to the Optionee, to repurchase all or any portion of
the Shares, at a price per share equal to the fair market value of such Shares
as of the close of business on the date of termination of the Optionee's
employment.  Such fair market value shall be determined by mutual agreement of
the Company and the Optionee.  Failing such agreement between the Optionee and
the Company within 30 days of the date of the Company's notice
<PAGE>

electing to repurchase such Shares, the fair market value of such Shares shall
be determined by three appraisers, one designated within five days after the
termination of said 30-day period by the Optionee or his or her legal
representatives (which appraiser shall not be the Optionee or his or her legal
representative), one within said period of five days by the Company (which
appraiser shall not be an officer, director or employee of the Company) and the
third within five days after said appointment last occurring by the two
appraisers so chosen. Successor appraisers, if any shall be required, shall be
appointed, within a reasonable time, as nearly as may be in the manner provided
as to the related original appointment. No appointment shall be deemed as having
been accomplished unless such appraiser shall have accepted in writing his
appointment as such within the time limited for his appointment. Notice of each
appointment of an appraiser shall be given promptly to the other parties in
interest. Any expenses relating to the appointment and service of an appraiser
shall be paid by the party appointing such appraiser or, in the case of the
appraiser appointed by the appraisers chosen by the Company and the Optionee,
shall be paid by the Company. Said appraisers shall proceed promptly to
determine the fair market value of said Share or Shares by agreement of any two
of the appraisers, which shall be conclusive upon all parties in interest in
such Shares. Promptly following such determination, the appraisers shall mail or
deliver such notice of such determination to the Optionee and the Company.

          (b) Repurchase Procedure.  Upon notice from the Company of exercise of
              --------------------
its rights under this Section 8 and determination of the purchase price for the
Shares so repurchased, the Optionee shall transfer the Shares or appropriate
part thereof to the Company against payment by the Company of the purchase price
therefor.  If upon the expiration of the 90-day period following the Optionee's
termination of employment the Company shall have failed to elect to repurchase
all of the Shares, the repurchase rights with respect to the Shares not so
elected to be repurchased imposed by this Section 8 shall terminate, and the
Optionee or his or her legal representatives may thereafter transfer such
Shares.  The Optionee or his or her legal representatives may in no event
transfer any Shares prior thereto, other than to the Company.

          (c) Failure of Optionee to Comply.  If the Optionee fails to comply
              -----------------------------
with any of the provisions of this Section 8, the Company, at its option and in
addition to its other remedies, may suspend the rights of the Optionee to vote
and to receive dividends on the Shares, or may refuse to register on its books
any transfer or change in the ownership of the Shares or in the right to vote
thereon, until the provisions of this Section 8 are complied with to the
satisfaction of the Company.

          (d) Expiration.  The restriction contained in this Section 8 shall
              ----------
expire upon the closing of the Company's initial public offering, underwritten
by a nationally recognized underwriter, pursuant to an effective registration
statement under the Securities Act (such expiration date shall be referred to
herein as the "Expiration Date").

          (e) Safekeeping.  The Optionee acknowledges that the Company may, in
              -----------
its discretion, retain for safekeeping stock certificates representing all
Shares purchased hereunder by the Optionee.  The Optionee further acknowledges
that the Company may, to insure that the Optionee complies with the restriction
of this Section 8, continue to retain such stock certificates until the earlier
of the Expiration Date or the date of expiration of these repurchase rights
under
<PAGE>

Section 8(b) above. At the time of any exercise of this option, in whole or in
part, the Optionee shall execute such further agreement as the Company may
require to implement the foregoing.

     9.   Right of First Refusal.
          ----------------------

          (a) General.  The Optionee shall not sell, assign, pledge, or in any
              -------
manner transfer any of the Shares or any right or interest therein, whether
voluntarily or by operation of law, or by gift or otherwise, except by a
transfer which meets the requirements of the provisions of this Section 9.

          (b) Restrictions on Transfer.  If at any time or from time to time the
              ------------------------
Optionee intends to sell or transfer any Shares to a third party, the Optionee
shall provide notice thereof to the Company prior to such transfer (which in the
case of a sale shall include a bona fide purchase agreement with a viable
purchaser).  The Company shall have an option for 30 days following the date of
receipt of the Optionee's notice to purchase such Shares on the terms upon which
the Shares were to be purchased by or transferred to the third party by the
Optionee.  If the Company does not exercise its right of first refusal under
this Section 9(b) with respect to such proposed sale or transfer within such 30-
day period, the Optionee shall be free to sell or transfer such Shares to the
third party identified in the Optionee's notice for a period of 45 days after
the expiration of the 30-day period following the date of receipt of the
Optionee's notice.  Such sale or transfer must be on terms no more favorable to
the recipient than those set forth in the Optionee's notice.  In no event may
Shares be sold or transferred to any then-current competitor of the Company.
Any transfer or sale of Shares by the Optionee will be conditional upon the
recipient acknowledging in writing the option set forth in this Section 9(b) and
the other restrictions to which the Shares are subject.

          (c) Failure of Optionee to Comply.  If the Optionee's notice in
              -----------------------------
respect of any Shares is not received by the Company as provided in Section 9(b)
above, or if the Optionee fails to comply with the provisions of Section 9(b)
above in respect of any such Shares in any other regard, the Company, at its
option and in addition to its other remedies, may suspend the rights to vote or
to receive dividends on said Shares, or may refuse to register on its books any
transfer or change in ownership of said Shares or in the right to vote thereon,
until the provisions of Section 9(b) are complied with to the satisfaction of
the Company; and if the required Optionee's notice is not received by the
Company after written demand by the Company, the Company may also independently
proceed as though a proper Optionee's notice has been received at the expiration
of ten days after mailing such demand, and, if the Company exercises its rights
under Section 9(b) with respect to said Shares or any of them, the Shares
specified shall be transferred accordingly.

          (d) Expiration.  The Company's right of first refusal contained in
              ----------
this Section 9 with respect to any sale or transfer of Shares shall expire upon
the Expiration Date.

     10.  No Special Employment Rights.  Nothing contained in the Plan or this
          ----------------------------
option shall be construed or deemed by any person under any circumstances to
bind the Company to continue the employment of the Optionee for the period
within which this option may be exercised.
<PAGE>

     11.  Rights as a Shareholder.  The Optionee shall have no rights as a
          -----------------------
shareholder with respect to any shares which may be purchased by exercise of
this option (including, without limitation, any rights to receive dividends or
non-cash distributions with respect to such shares) unless and until a
certificate representing such shares is duly issued and delivered to the
Optionee.  No adjustment shall be made for dividends or other rights for which
the record date is prior to the date such stock certificate is issued.

     12.  Adjustment Provisions.
          ---------------------

          (a) General.  In the event of a consolidation, merger or other
              -------
reorganization in which all of the outstanding shares of Common Stock are
exchanged for securities, cash or other property of any other corporation or
business entity (an "Acquisition") or in the event of a liquidation of the
Company, the Board of Directors of the Company or the board of directors of any
corporation assuming the obligations of the Company, may, in its discretion,
take any one or more of the following actions as to this option:  (i) provide
that this option shall be assumed, or a substantially equivalent option shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof) on such terms as the Board determines to be appropriate, (ii) upon
written notice to the Optionee, provide that if unexercised, this option will
terminate immediately prior to the consummation of such transaction unless
exercised by the Optionee within a specified period following the date of such
notice, (iii) in the event of an Acquisition under the terms of which holders of
the Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the Acquisition (the "Acquisition Price"),
make or provide for a cash payment to the Optionee equal to the difference
between (A) the Acquisition Price times the number of shares of Common Stock
subject to outstanding options (to the extent then exercisable at prices not in
excess of the Acquisition Price) and (B) the aggregate exercise price of all
such outstanding options in exchange for the termination of such options, and
(iv) provide that all or any outstanding options shall become exercisable or
realizable in full prior to the effective date of such Acquisition.

          (b) Board Authority to Make Adjustments.  Any adjustments under this
              -----------------------------------
Section 12 will be made by the Board of Directors, whose determination as to
what adjustments, if any, will be made and the extent thereof will be final,
binding and conclusive.  No fractional shares will be issued pursuant to this
option on account of any such adjustments.

     13.  Withholding Taxes.  The Company's obligation to deliver shares upon
          -----------------
the exercise of this option shall be subject to the Optionee's satisfaction of
all applicable federal, state and local income and employment tax withholding
requirements.

     14.  Investment Representations; Legends.
          -----------------------------------

          (a) Representations.  The Optionee represents, warrants and covenants
              ---------------
that:

          (i) Any shares purchased upon exercise of this option shall be
     acquired for the Optionee's account for investment only and not with a view
     to, or for sale in
<PAGE>

     connection with, any distribution of the shares in violation of the
     Securities Act or any rule or regulation under the Securities Act.

          (ii)  The Optionee has had such opportunity as he or she has deemed
     adequate to obtain from representatives of the Company such information as
     is necessary to permit the Optionee to evaluate the merits and risks of his
     or her investment in the Company.

          (iii) The Optionee is able to bear the economic risk of holding
     shares acquired pursuant to the exercise of this option for an indefinite
     period.

          (iv)  The Optionee understands that (A) the shares acquired pursuant
     to the exercise of this option will not be registered under the Securities
     Act and are "restricted securities" within the meaning of Rule 144 under
     the Securities Act; (B) such shares cannot be sold, transferred or
     otherwise disposed of unless they are subsequently registered under the
     Securities Act or an exemption from registration is then available; (C) in
     any event, an exemption from registration under Rule 144 or otherwise under
     the Securities Act may not be available for at least two years and even
     then will not be available unless a public market then exists for the
     Common Stock, adequate information concerning the Company is then available
     to the public and other terms and conditions of Rule 144 are complied with;
     and (D) there is now no registration statement on file with the Securities
     and Exchange Commission with respect to any stock of the Company and the
     Company has no obligation or current intention to register any shares
     acquired pursuant to the exercise of this option under the Securities Act.

          (v)   The Optionee agrees that, if the Company offers for the first
     time any of its Common Stock for sale pursuant to a registration statement
     under the Securities Act, the Optionee will not, without the prior written
     consent of the Company, publicly offer, sell, contract to sell or otherwise
     dispose of, directly or indirectly, any shares purchased upon exercise of
     this option for a period of 180 days after the effective date of such
     registration statement.

By making payment upon exercise of this option, the Optionee shall be deemed to
have reaffirmed, as of the date of such payment, the representations made in
this Section 14.

          (b)   Legends on Stock Certificates.  All stock certificates
                -----------------------------
representing shares of Common Stock issued to the Optionee upon exercise of this
option shall have affixed thereto legends substantially in the following forms,
in addition to any other legends required by applicable state law:

     "The shares of stock represented by this certificate have not been
     registered under the Securities Act of 1933 and may not be transferred,
     sold or otherwise disposed of in the absence of an effective registration
     statement with respect to the shares evidenced by this certificate, filed
     and made effective under the Securities Act of 1933, or an opinion of
     counsel satisfactory to the Company to the effect that registration under
     such Act is not required."
<PAGE>

     "The shares of stock represented by this certificate are subject to certain
     restrictions on transfer and repurchase rights contained in an Option
     Agreement, a copy of which will be furnished upon request by the issuer."

To ensure compliance with the terms of this agreement, the Company may issue to
its transfer agent appropriate stop transfer instructions with respect to the
Shares.

     15.  Miscellaneous.
          -------------

          (a) The Board may amend, modify or terminate any outstanding option,
including substituting therefor another option of the same or a different type,
changing the date of exercise or realization, provided that the Optionee's
consent to such action shall be required unless the Board determines that the
action, taking into account any related action, would not materially and
adversely affect the Optionee.  The Board may at any time accelerate the time at
which all or any part of an Option may be exercised.

          (b) All notices under this option shall be mailed or delivered by hand
              to the parties at their respective addresses set forth beneath
              their names below or at such other address as may be designated in
              writing by either of the parties to one another.

          (c) This option shall be governed by and construed in accordance with
              the laws of the Commonwealth of Massachusetts.

The right of exercise shall be cumulative so that if the option is not exercised
to the maximum extent permissible during any exercise period, it shall be
exercisable, in whole or in part, with respect to all shares not so purchased at
any time prior to the Final Exercise Date or the earlier termination of this
option.  This option may not be exercised at any time on or after the Final
Exercise Date.
<PAGE>

          Notwithstanding anything to the contrary in this option or in the
Plan, this option will vest as to 100% of the then-unvested shares upon the
occurrence of a Change of Control (as defined herein). For the purposes of this
option, a "Change of Control" shall mean an event or occurrence set forth in any
one or more of clauses (i) through (iv) below (including an event or occurrence
that constitutes a Change in Control under one of such subsections but is
specifically exempted from another such subsection):

     (i)   the acquisition by an individual, entity or group (within the meaning
     of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as
     amended (the "Exchange Act")) (a "Person"), other than Banyan Worldwide or
     CBS Corporation, of beneficial ownership of any capital stock of the
     Company if, after such acquisition, such Person beneficially owns (within
     the meaning of Rule 13d-3 promulgated under the Exchange Act) 20% or more
     of either (A) the then-outstanding shares of common stock of the Company
     (the "Outstanding Company Common Stock") or (B) the combined voting power
     of the then-outstanding securities of the Company entitled to vote
     generally in the election of directors (the "Outstanding Company Voting
     Securities"); provided, however, that for purposes of this clause (i), the
                   --------
     following acquisitions shall not constitute a Change in Control: (I) any
     acquisition directly from the Company (excluding an acquisition pursuant to
     the exercise, conversion or exchange of any security exercisable for,
     convertible into or exchangeable for common stock or voting securities of
     the Company, unless the Person exercising, converting or exchanging such
     security acquired such security directly from the Company or an underwriter
     or agent of the Company), (II) any acquisition by the Company, (III) any
     acquisition by any employee benefit plan (or related trust) sponsored or
     maintained by the Company or any corporation controlled by the Company, or
     (IV) any acquisition by any corporation pursuant to a transaction which
     complies with clauses (A) and (B) of clause (iii) of this Section 3(a); or

     (ii)  such time as the Continuing Directors (as defined below) do not
     constitute a majority of the Board (or, if applicable, the Board of
     Directors of a successor corporation to the Company), where the term
     "Continuing Director" means at any date a member of the  Board (A) who was
     a member of the Board on the date of the execution of this Agreement or (B)
     who was nominated or elected subsequent to such date by at least a majority
     of the directors who were Continuing Directors at the time of such
     nomination or election or whose election to the Board was recommended or
     endorsed by at least a majority of the directors who were Continuing
     Directors at the time of such nomination or election; provided, however,
                                                           --------  -------
     that there shall be excluded from this clause (B) any individual whose
     initial assumption of office occurred as a result of an actual or
     threatened election contest with respect to the election or removal of
     directors or other actual or threatened solicitation of proxies or
     consents, by or on behalf of a person other than the Board; or

     (iii) the consummation of a merger, consolidation, reorganization,
     recapitalization or statutory share exchange involving the Company or a
     sale or other disposition of all or substantially all of the assets of the
     Company (a "Business Combination"), unless, immediately following such
     Business Combination, each of the following two conditions is satisfied:
     (A) all or substantially all of the individuals and entities who were the
<PAGE>

     beneficial owners of the Outstanding Company Common Stock and Outstanding
     Company Voting Securities immediately prior to such Business Combination
     beneficially own, directly or indirectly, more than 50% of the then-
     outstanding shares of common stock and the combined voting power of the
     then-outstanding securities entitled to vote generally in the election of
     directors, respectively, of the resulting or acquiring corporation in such
     Business Combination (which shall include, without limitation, a
     corporation which as a result of such transaction owns the Company or
     substantially all of the Company's assets either directly or through one or
     more subsidiaries) (such resulting or acquiring corporation is referred to
     herein as the "Acquiring Corporation") in substantially the same
     proportions as their ownership, immediately prior to such Business
     Combination, of the Outstanding Company Common Stock and Outstanding
     Company Voting Securities, respectively; and (B) no Person (excluding the
     Acquiring Corporation or any employee benefit plan (or related trust)
     maintained or sponsored by the Company or by the Acquiring Corporation)
     beneficially owns, directly or indirectly, 20% or more of the then
     outstanding shares of common stock of the Acquiring Corporation, or of the
     combined voting power of the then-outstanding securities of such
     corporation entitled to vote generally in the election of directors (except
     to the extent that such ownership existed prior to the Business
     Combination); or

     (iv) approval by the stockholders of the Company of a complete liquidation
          or dissolution of the Company.


          (b) Exercise Procedure. Subject to the conditions set forth in this
              ------------------
Agreement, this option shall be exercised by the Optionee's delivery of written
notice of exercise to the Treasurer of the Company, specifying the number of
shares to be purchased and the purchase price to be paid therefor and
accompanied by payment in full in accordance with Section 4. Such exercise shall
be effective upon receipt by the Treasurer of the Company of such written notice
together with the required payment. The Optionee may purchase less than the
number of shares covered hereby, provided that no partial exercise of this
option may be for any fractional share or for fewer than ten whole shares.

          (c) Continuous Relationship with the Company Required.  This option
              -------------------------------------------------
may not be exercised unless the Optionee, at the time he or she exercises this
option, is, and has been at all times since the date of grant of this option, an
employee of either the Company or Banyan Worldwide, officer or director of, or
consultant or advisor to, the Company (an "Eligible Optionee").

          (d) Termination of Employment.  If the Optionee ceases to be employed
              -------------------------
by the Company for any reason (including without limitation death, disability,
or voluntary or involuntary termination), then the right to exercise this option
shall terminate 30 days after such cessation.

          (e) Early Exercise Alternative.  Notwithstanding the exercisability
              --------------------------
schedule set forth in paragraph (a), the Optionee may elect to exercise this
option as to the unvested shares (in addition to the vested shares) if
simultaneously with such exercise the Optionee enters into a Stock Restriction
Agreement with the Company in the form attached hereto as Exhibit A (the "Stock
                                                          ---------
Restriction Agreement"). The Stock Restriction Agreement provides that the
unvested shares shall be subject to a right of repurchase (the "Purchase
Option") in favor of the Company at the $8.50 exercise price (as adjusted
pursuant to the terms hereof) in the event that the Optionee ceases to be
employed by the Company.

     4.   Payment of Purchase Price.
          -------------------------
<PAGE>

          (a) Method of Payment.  Payment of the purchase price for shares
              -----------------
purchased upon exercise of this option shall be made by delivery of cash or a
check in an amount equal to the exercise price of such option or, with the prior
consent of the Company (which may be withheld in its sole discretion), by (A)
delivery of shares of Common Stock owned by the Optionee for at least six
months, valued at their fair market value, as determined in (b) below, (B)
delivery of a promissory note of the Optionee to the Company on terms determined
by the Board, (C) delivery of an irrevocable undertaking by a broker to deliver
promptly to the Company sufficient funds to pay the exercise price or delivery
of irrevocable instructions to a broker to deliver promptly to the Company cash
or a check sufficient to pay the exercise price, (D) payment of such other
lawful consideration as the Board may determine, or (E) any combination of the
foregoing.

          (b) Valuation of Shares or Other Non-Cash Consideration Tendered in
              ---------------------------------------------------------------
Payment of Purchase Price.  For the purposes hereof, the fair market value of
- -------------------------
any share of the Company's Common Stock or other non-cash consideration which
may be delivered to the Company in exercise of this option shall be determined
in good faith by the Board of Directors of the Company.

          (c) Delivery of Shares Tendered in Payment of Purchase Price.  If the
              --------------------------------------------------------
Optionee exercises this option by delivery of shares of Common Stock of the
Company, the certificate or certificates representing the shares of Common Stock
of the Company to be delivered shall be duly executed in blank by the Optionee
or shall be accompanied by a stock power duly executed in blank suitable for
purposes of transferring such shares to the Company.  Fractional shares of
Common Stock of the Company will not be accepted in payment of the purchase
price of shares acquired upon exercise of this option.

          (d) Restrictions on Use of Option Stock.  Notwithstanding the
              -----------------------------------
foregoing, no shares of Common Stock of the Company may be tendered in payment
of the purchase price of shares purchased upon exercise of this option if the
shares to be so tendered were acquired within six (6) months before the date of
such tender, through the exercise of an option granted under the Plan or any
other stock option or restricted stock plan of the Company.

     5.   Delivery of Shares; Compliance With Securities Laws, Etc.
          --------------------------------------------------------

          (a) General.  The Company shall, upon payment of the option price for
              -------
the number of shares purchased and paid for, make prompt delivery of such shares
to the Optionee, provided that if any law or regulation requires the Company to
take any action with respect to such shares before the issuance thereof, then
the date of delivery of such shares shall be extended for the period necessary
to complete such action.

          (b) Compliance With Securities Laws, Etc.  The Company will not be
              -------------------------------------
obligated to deliver any shares of Common Stock pursuant to the Plan or to
remove restriction from shares previously delivered under the Plan (i) until all
conditions of the option have been satisfied or removed, (ii) until, in the
opinion of the Company's counsel, all applicable federal and state laws and
regulation have been complied with, (iii) if the outstanding Stock is at the
time listed on any stock exchange, until the shares to be delivered have been
listed or authorized
<PAGE>

to be listed on such exchange upon official notice of issuance, and (iv) until
all other legal matters in connection with the issuance and delivery of such
shares have been approved by the Company's counsel.

     6.   Nontransferability of Option.  This option is personal and no rights
          ----------------------------
granted hereunder may be transferred, assigned, pledged or hypothecated in any
way (whether by operation of law or otherwise) nor shall any such rights be
subject to execution, attachment or similar process.  Upon any attempt to
transfer, assign, pledge, hypothecate or otherwise dispose of this option or of
such rights contrary to the provisions hereof, or upon the levy of any
attachment or similar process upon this option or such rights, this option and
such rights shall, at the election of the Company, become null and void.

     7.   Proxy.  The Optionee hereby appoints Banyan Worldwide, a Massachusetts
          -----
corporation, and/or its designee(s) ("Banyan"), as the Optionee's attorney-in-
fact and proxy, with full power of substitution, for and in the Optionee's name,
to vote, express consent or disapproval, or otherwise act in such manner
(including pursuant to written consent) and upon such matters as Banyan or its
designee(s), proxy or substitute(s) shall, in its or their sole discretion, deem
proper with respect to any and all of the shares issued upon any exercise of
this option or issued in respect to such shares as a stock dividend, stock split
or otherwise (collectively, for purposes of Sections 7, 8 and 9 hereof, the
"Shares").  The proxy granted hereby shall be irrevocable and may be exercised
at any meeting or in respect of any written consent of stockholders.  This proxy
is coupled with an interest sufficient in law to support such proxy.  This proxy
shall remain in full force and effect and be enforceable against any donee,
transferee or assignee of the stock.  In addition to any other applicable
limitations pursuant to the terms of this option, the Optionee agrees not to
sell, assign, transfer, loan, tender, pledge, hypothecate, exchange, encumber or
otherwise dispose of, or issue an option or call with respect to, any of the
Shares, or impair such Shares, in each case unless, and as a condition precedent
thereto, the transferee of such Shares executes and delivers to Banyan an
agreement to be bound by the terms of this Section 7.  Any purported transfer in
violation of this Section 7 shall be null and void and shall not be recognized
by the Company or reflected on the stock records of the Company.  The Optionee
shall cause the Company to require any certificates representing any and all
Shares issued upon any exercise of this option to bear a legend referencing the
restrictions on transfer set for in this Section 7, which legend shall be
subject to the approval of Banyan.  Notwithstanding anything to the contrary in
the foregoing, the provisions of, including, without limitation, the proxy
appointed by, this Section 7 shall terminate upon the closing of the Company's
initial public offering, underwritten by a nationally recognized underwriter,
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "Securities Act").

     8.   Repurchase of Shares Upon Termination of Employment.  The following
          ---------------------------------------------------
repurchase provisions shall apply to any and all Shares;

          (a) Repurchase Rights.  If the Optionee for any reason whatsoever
              -----------------
(including without limitation death, disability, or voluntary or involuntary
termination) ceases to be employed by the Company or Banyan Worldwide, or
providing services on behalf of the Company or Banyan Worldwide, prior to the
date specified in Section 8(d) below for the
<PAGE>

expiration of these restrictions, then during the 90-day period following such
termination the Company may elect, by written notice delivered to the Optionee,
to repurchase all or any portion of the Shares, at a price per share equal to
the fair market value of such Shares as of the close of business on the date of
termination of the Optionee's employment. Such fair market value shall be
determined by mutual agreement of the Company and the Optionee. Failing such
agreement between the Optionee and the Company within 30 days of the date of the
Company's notice electing to repurchase such Shares, the fair market value of
such Shares shall be determined by three appraisers, one designated within five
days after the termination of said 30-day period by the Optionee or his or her
legal representatives (which appraiser shall not be the Optionee or his or her
legal representative), one within said period of five days by the Company (which
appraiser shall not be an officer, director or employee of the Company) and the
third within five days after said appointment last occurring by the two
appraisers so chosen. Successor appraisers, if any shall be required, shall be
appointed, within a reasonable time, as nearly as may be in the manner provided
as to the related original appointment. No appointment shall be deemed as having
been accomplished unless such appraiser shall have accepted in writing his
appointment as such within the time limited for his appointment. Notice of each
appointment of an appraiser shall be given promptly to the other parties in
interest. Any expenses relating to the appointment and service of an appraiser
shall be paid by the party appointing such appraiser or, in the case of the
appraiser appointed by the appraisers chosen by the Company and the Optionee,
shall be paid by the Company. Said appraisers shall proceed promptly to
determine the fair market value of said Share or Shares by agreement of any two
of the appraisers, which shall be conclusive upon all parties in interest in
such Shares. Promptly following such determination, the appraisers shall mail or
deliver such notice of such determination to the Optionee and the Company.

          (b) Repurchase Procedure.  Upon notice from the Company of exercise of
              --------------------
its rights under this Section 8 and determination of the purchase price for the
Shares so repurchased, the Optionee shall transfer the Shares or appropriate
part thereof to the Company against payment by the Company of the purchase price
therefor.  If upon the expiration of the 90-day period following the Optionee's
termination of employment the Company shall have failed to elect to repurchase
all of the Shares, the repurchase rights with respect to the Shares not so
elected to be repurchased imposed by this Section 8 shall terminate, and the
Optionee or his or her legal representatives may thereafter transfer such
Shares.  The Optionee or his or her legal representatives may in no event
transfer any Shares prior thereto, other than to the Company.

          (c) Failure of Optionee to Comply.  If the Optionee fails to comply
              -----------------------------
with any of the provisions of this Section 8, the Company, at its option and in
addition to its other remedies, may suspend the rights of the Optionee to vote
and to receive dividends on the Shares, or may refuse to register on its books
any transfer or change in the ownership of the Shares or in the right to vote
thereon, until the provisions of this Section 8 are complied with to the
satisfaction of the Company.

          (d) Expiration.  The restriction contained in this Section 8 shall
              ----------
expire upon the closing of the Company's initial public offering, underwritten
by a nationally recognized underwriter, pursuant to an effective registration
statement under the Securities Act (such expiration date shall be referred to
herein as the "Expiration Date").
<PAGE>

          (e) Safekeeping.  The Optionee acknowledges that the Company may, in
              -----------
its discretion, retain for safekeeping stock certificates representing all
Shares purchased hereunder by the Optionee.  The Optionee further acknowledges
that the Company may, to insure that the Optionee complies with the restriction
of this Section 8, continue to retain such stock certificates until the earlier
of the Expiration Date or the date of expiration of these repurchase rights
under Section 8(b) above.  At the time of any exercise of this option, in whole
or in part, the Optionee shall execute such further agreement as the Company may
require to implement the foregoing.

     9.   Right of First Refusal.
          ----------------------

          (a) General.  The Optionee shall not sell, assign, pledge, or in any
              -------
manner transfer any of the Shares or any right or interest therein, whether
voluntarily or by operation of law, or by gift or otherwise, except by a
transfer which meets the requirements of the provisions of this Section 9.

          (b) Restrictions on Transfer.  If at any time or from time to time the
              ------------------------
Optionee intends to sell or transfer any Shares to a third party, the Optionee
shall provide notice thereof to the Company prior to such transfer (which in the
case of a sale shall include a bona fide purchase agreement with a viable
purchaser).  The Company shall have an option for 30 days following the date of
receipt of the Optionee's notice to purchase such Shares on the terms upon which
the Shares were to be purchased by or transferred to the third party by the
Optionee.  If the Company does not exercise its right of first refusal under
this Section 9(b) with respect to such proposed sale or transfer within such 30-
day period, the Optionee shall be free to sell or transfer such Shares to the
third party identified in the Optionee's notice for a period of 45 days after
the expiration of the 30-day period following the date of receipt of the
Optionee's notice.  Such sale or transfer must be on terms no more favorable to
the recipient than those set forth in the Optionee's notice.  In no event may
Shares be sold or transferred to any then-current competitor of the Company.
Any transfer or sale of Shares by the Optionee will be conditional upon the
recipient acknowledging in writing the option set forth in this Section 9(b) and
the other restrictions to which the Shares are subject.

          (c) Failure of Optionee to Comply.  If the Optionee's notice in
              -----------------------------
respect of any Shares is not received by the Company as provided in Section 9(b)
above, or if the Optionee fails to comply with the provisions of Section 9(b)
above in respect of any such Shares in any other regard, the Company, at its
option and in addition to its other remedies, may suspend the rights to vote or
to receive dividends on said Shares, or may refuse to register on its books any
transfer or change in ownership of said Shares or in the right to vote thereon,
until the provisions of Section 9(b) are complied with to the satisfaction of
the Company; and if the required Optionee's notice is not received by the
Company after written demand by the Company, the Company may also independently
proceed as though a proper Optionee's notice has been received at the expiration
of ten days after mailing such demand, and, if the Company exercises its rights
under Section 9(b) with respect to said Shares or any of them, the Shares
specified shall be transferred accordingly.

          (d) Expiration.  The Company's right of first refusal contained in
              ----------
this Section 9 with respect to any sale or transfer of Shares shall expire upon
the Expiration Date.
<PAGE>

     10.  No Special Employment Rights.  Nothing contained in the Plan or this
          ----------------------------
option shall be construed or deemed by any person under any circumstances to
bind the Company to continue the employment of the Optionee for the period
within which this option may be exercised.

     11.  Rights as a Shareholder.  The Optionee shall have no rights as a
          -----------------------
shareholder with respect to any shares which may be purchased by exercise of
this option (including, without limitation, any rights to receive dividends or
non-cash distributions with respect to such shares) unless and until a
certificate representing such shares is duly issued and delivered to the
Optionee.  No adjustment shall be made for dividends or other rights for which
the record date is prior to the date such stock certificate is issued.

     12.  Adjustment Provisions.
          ---------------------

          (a) General.  In the event of a consolidation, merger or other
              -------
reorganization in which all of the outstanding shares of Common Stock are
exchanged for securities, cash or other property of any other corporation or
business entity (an "Acquisition") or in the event of a liquidation of the
Company, the Board of Directors of the Company or the board of directors of any
corporation assuming the obligations of the Company, may, in its discretion,
take any one or more of the following actions as to this option:  (i) provide
that this option shall be assumed, or a substantially equivalent option shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof) on such terms as the Board determines to be appropriate, (ii) upon
written notice to the Optionee, provide that if unexercised, this option will
terminate immediately prior to the consummation of such transaction unless
exercised by the Optionee within a specified period following the date of such
notice, (iii) in the event of an Acquisition under the terms of which holders of
the Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the Acquisition (the "Acquisition Price"),
make or provide for a cash payment to the Optionee equal to the difference
between (A) the Acquisition Price times the number of shares of Common Stock
subject to outstanding options (to the extent then exercisable at prices not in
excess of the Acquisition Price) and (B) the aggregate exercise price of all
such outstanding options in exchange for the termination of such options, and
(iv) provide that all or any outstanding options shall become exercisable or
realizable in full prior to the effective date of such Acquisition.

          (b) Board Authority to Make Adjustments.  Any adjustments under this
              -----------------------------------
Section 12 will be made by the Board of Directors, whose determination as to
what adjustments, if any, will be made and the extent thereof will be final,
binding and conclusive.  No fractional shares will be issued pursuant to this
option on account of any such adjustments.

     13.  Withholding Taxes.  The Company's obligation to deliver shares upon
          -----------------
the exercise of this option shall be subject to the Optionee's satisfaction of
all applicable federal, state and local income and employment tax withholding
requirements.

     14.  Investment Representations; Legends.
          -----------------------------------
<PAGE>

          (a)   Representations.  The Optionee represents, warrants and
                ---------------
covenants that:

          (i)   Any shares purchased upon exercise of this option shall be
     acquired for the Optionee's account for investment only and not with a view
     to, or for sale in connection with, any distribution of the shares in
     violation of the Securities Act or any rule or regulation under the
     Securities Act.

          (ii)  The Optionee has had such opportunity as he or she has deemed
     adequate to obtain from representatives of the Company such information as
     is necessary to permit the Optionee to evaluate the merits and risks of his
     or her investment in the Company.

          (iii) The Optionee is able to bear the economic risk of holding
     shares acquired pursuant to the exercise of this option for an indefinite
     period.

          (iv)  The Optionee understands that (A) the shares acquired pursuant
     to the exercise of this option will not be registered under the Securities
     Act and are "restricted securities" within the meaning of Rule 144 under
     the Securities Act; (B) such shares cannot be sold, transferred or
     otherwise disposed of unless they are subsequently registered under the
     Securities Act or an exemption from registration is then available; (C) in
     any event, an exemption from registration under Rule 144 or otherwise under
     the Securities Act may not be available for at least two years and even
     then will not be available unless a public market then exists for the
     Common Stock, adequate information concerning the Company is then available
     to the public and other terms and conditions of Rule 144 are complied with;
     and (D) there is now no registration statement on file with the Securities
     and Exchange Commission with respect to any stock of the Company and the
     Company has no obligation or current intention to register any shares
     acquired pursuant to the exercise of this option under the Securities Act.

          (v)   The Optionee agrees that, if the Company offers for the first
     time any of its Common Stock for sale pursuant to a registration statement
     under the Securities Act, the Optionee will not, without the prior written
     consent of the Company, publicly offer, sell, contract to sell or otherwise
     dispose of, directly or indirectly, any shares purchased upon exercise of
     this option for a period of 180 days after the effective date of such
     registration statement.

By making payment upon exercise of this option, the Optionee shall be deemed to
have reaffirmed, as of the date of such payment, the representations made in
this Section 14.

          (b)   Legends on Stock Certificates.  All stock certificates
                -----------------------------
representing shares of Common Stock issued to the Optionee upon exercise of this
option shall have affixed thereto legends substantially in the following forms,
in addition to any other legends required by applicable state law:

     "The shares of stock represented by this certificate have not been
     registered under the Securities Act of 1933 and may not be transferred,
     sold or otherwise disposed of in the absence of an effective registration
     statement with respect to the shares evidenced by this
<PAGE>

     certificate, filed and made effective under the Securities Act of 1933, or
     an opinion of counsel satisfactory to the Company to the effect that
     registration under such Act is not required."

     "The shares of stock represented by this certificate are subject to certain
     restrictions on transfer and repurchase rights contained in an Option
     Agreement, a copy of which will be furnished upon request by the issuer."

To ensure compliance with the terms of this agreement, the Company may issue to
its transfer agent appropriate stop transfer instructions with respect to the
Shares.

     15.  Miscellaneous.
          -------------

adversely affect the Optionee.  The Board may at any time accelerate the time at
which all or any part of an Option may be exercised.

          (b) All notices under this option shall be mailed or delivered by hand
to the parties at their respective addresses set forth beneath their names below

<PAGE>

     Notwithstanding anything to the contrary in this option or in the Plan,
this option will vest as to 100% of the then-unvested shares upon the occurrence
of a Change of Control (as defined herein).  For the purposes of this option, a
"Change of Control" shall mean an event or occurrence set forth in any one or
more of clauses (i) through (iv) below (including an event or occurrence that
constitutes a Change in Control under one of such subsections but is
specifically exempted from another such subsection):

     (i)   the acquisition by an individual, entity or group (within the meaning
     of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as
     amended (the "Exchange Act")) (a "Person"), other than Banyan Worldwide or
     CBS Corporation, of beneficial ownership of any capital stock of the
     Company if, after such acquisition, such Person beneficially owns (within
     the meaning of Rule 13d-3 promulgated under the Exchange Act) 20% or more
     of either (A) the then-outstanding shares of common stock of the Company
     (the "Outstanding Company Common Stock") or (B) the combined voting power
     of the then-outstanding securities of the Company entitled to vote
     generally in the election of directors (the "Outstanding Company Voting
     Securities"); provided, however, that for purposes of this clause (i), the
                   --------
     following acquisitions shall not constitute a Change in Control: (I) any
     acquisition directly from the Company (excluding an acquisition pursuant to
     the exercise, conversion or exchange of any security exercisable for,
     convertible into or exchangeable for common stock or voting securities of
     the Company, unless the Person exercising, converting or exchanging such
     security acquired such security directly from the Company or an underwriter
     or agent of the Company), (II) any acquisition by the Company, (III) any
     acquisition by any employee benefit plan (or related trust) sponsored or
     maintained by the Company or any corporation controlled by the Company, or
     (IV) any acquisition by any corporation pursuant to a transaction which
     complies with clauses (A) and (B) of clause (iii) of this Section 3(a); or

     (ii)  such time as the Continuing Directors (as defined below) do not
     constitute a majority of the Board (or, if applicable, the Board of
     Directors of a successor corporation to the Company), where the term
     "Continuing Director" means at any date a member of the  Board (A) who was
     a member of the Board on the date of the execution of this Agreement or (B)
     who was nominated or elected subsequent to such date by at least a majority
     of the directors who were Continuing Directors at the time of such
     nomination or election or whose election to the Board was recommended or
     endorsed by at least a majority of the directors who were Continuing
     Directors at the time of such nomination or election; provided, however,
                                                           --------  -------
     that there shall be excluded from this clause (B) any individual whose
     initial assumption of office occurred as a result of an actual or
     threatened election contest with respect to the election or removal of
     directors or other actual or threatened solicitation of proxies or
     consents, by or on behalf of a person other than the Board; or

     (iii) the consummation of a merger, consolidation, reorganization,
     recapitalization or statutory share exchange involving the Company or a
     sale or other disposition of all or substantially all of the assets of the
     Company (a "Business Combination"), unless, immediately following such
     Business Combination, each of the following two conditions is satisfied:
     (A) all or substantially all of the individuals and entities who were the
<PAGE>

     beneficial owners of the Outstanding Company Common Stock and Outstanding
     Company Voting Securities immediately prior to such Business Combination
     beneficially own, directly or indirectly, more than 50% of the then-
     outstanding shares of common stock and the combined voting power of the
     then-outstanding securities entitled to vote generally in the election of
     directors, respectively, of the resulting or acquiring corporation in such
     Business Combination (which shall include, without limitation, a
     corporation which as a result of such transaction owns the Company or
     substantially all of the Company's assets either directly or through one or
     more subsidiaries) (such resulting or acquiring corporation is referred to
     herein as the "Acquiring Corporation") in substantially the same
     proportions as their ownership, immediately prior to such Business
     Combination, of the Outstanding Company Common Stock and Outstanding
     Company Voting Securities, respectively; and (B) no Person (excluding the
     Acquiring Corporation or any employee benefit plan (or related trust)
     maintained or sponsored by the Company or by the Acquiring Corporation)
     beneficially owns, directly or indirectly, 20% or more of the then
     outstanding shares of common stock of the Acquiring Corporation, or of the
     combined voting power of the then-outstanding securities of such
     corporation entitled to vote generally in the election of directors (except
     to the extent that such ownership existed prior to the Business
     Combination); or

     (iv) approval by the stockholders of the Company of a complete liquidation
          or dissolution of the Company.


          (b)  Exercise Procedure.  Subject to the conditions set forth in this
               ------------------
Agreement, this option shall be exercised by the Optionee's delivery of written
notice of exercise to the Treasurer of the Company, specifying the number of
shares to be purchased and the purchase price to be paid therefor and
accompanied by payment in full in accordance with Section 4. Such exercise shall
be effective upon receipt by the Treasurer of the Company of such written notice
together with the required payment. The Optionee may purchase less than the
number of shares covered hereby, provided that no partial exercise of this
option may be for any fractional share or for fewer than ten whole shares.

          (c) Continuous Relationship with the Company Required.  This option
              -------------------------------------------------
may not be exercised unless the Optionee, at the time he or she exercises this
option, is, and has been at all times since the date of grant of this option, an
employee of either the Company or Banyan Worldwide, officer or director of, or
consultant or advisor to, the Company (an "Eligible Optionee").

          (d) Termination of Employment.  If the Optionee ceases to be employed
              -------------------------
by the Company for any reason (including without limitation death, disability,
or voluntary or involuntary termination), then the right to exercise this option
shall terminate 30 days after such cessation.

          (e) Early Exercise Alternative.  Notwithstanding the exercisability
              --------------------------
schedule set forth in paragraph (a), the Optionee may elect to exercise this
option as to the unvested shares (in addition to the vested shares) if
simultaneously with such exercise the Optionee enters into a Stock Restriction
Agreement with the Company in the form attached hereto as Exhibit A
                                                          ---------
(the "Stock Restriction Agreement"). The Stock Restriction Agreement provides
that the unvested shares shall be subject to a right of repurchase (the
"Purchase Option") in favor of the Company at the $8.50 exercise price (as
adjusted pursuant to the terms hereof) in the event that the Optionee ceases to
be employed by the Company.

     4.   Payment of Purchase Price.
          -------------------------
<PAGE>

          (a) Method of Payment.  Payment of the purchase price for shares
              -----------------
purchased upon exercise of this option shall be made by delivery of cash or a
check in an amount equal to the exercise price of such option or, with the prior
consent of the Company (which may be withheld in its sole discretion), by (A)
delivery of shares of Common Stock owned by the Optionee for at least six
months, valued at their fair market value, as determined in (b) below, (B)
delivery of a promissory note of the Optionee to the Company on terms determined
by the Board, (C) delivery of an irrevocable undertaking by a broker to deliver
promptly to the Company sufficient funds to pay the exercise price or delivery
of irrevocable instructions to a broker to deliver promptly to the Company cash
or a check sufficient to pay the exercise price, (D) payment of such other
lawful consideration as the Board may determine, or (E) any combination of the
foregoing.

          (b) Valuation of Shares or Other Non-Cash Consideration Tendered in
              ---------------------------------------------------------------
Payment of Purchase Price.  For the purposes hereof, the fair market value of
- -------------------------
any share of the Company's Common Stock or other non-cash consideration which
may be delivered to the Company in exercise of this option shall be determined
in good faith by the Board of Directors of the Company.

          (c) Delivery of Shares Tendered in Payment of Purchase Price.  If the
              --------------------------------------------------------
Optionee exercises this option by delivery of shares of Common Stock of the
Company, the certificate or certificates representing the shares of Common Stock
of the Company to be delivered shall be duly executed in blank by the Optionee
or shall be accompanied by a stock power duly executed in blank suitable for
purposes of transferring such shares to the Company.  Fractional shares of
Common Stock of the Company will not be accepted in payment of the purchase
price of shares acquired upon exercise of this option.

          (d) Restrictions on Use of Option Stock.  Notwithstanding the
              -----------------------------------
foregoing, no shares of Common Stock of the Company may be tendered in payment
of the purchase price of shares purchased upon exercise of this option if the
shares to be so tendered were acquired within six (6) months before the date of
such tender, through the exercise of an option granted under the Plan or any
other stock option or restricted stock plan of the Company.

     5.   Delivery of Shares; Compliance With Securities Laws, Etc.
          --------------------------------------------------------

          (a) General.  The Company shall, upon payment of the option price for
              -------
the number of shares purchased and paid for, make prompt delivery of such shares
to the Optionee, provided that if any law or regulation requires the Company to
take any action with respect to such shares before the issuance thereof, then
the date of delivery of such shares shall be extended for the period necessary
to complete such action.

          (b) Compliance With Securities Laws, Etc.  The Company will not be
              -------------------------------------
obligated to deliver any shares of Common Stock pursuant to the Plan or to
remove restriction from shares previously delivered under the Plan (i) until all
conditions of the option have been satisfied or removed, (ii) until, in the
opinion of the Company's counsel, all applicable federal and state laws and
regulation have been complied with, (iii) if the outstanding Stock is at the
time listed on any stock exchange, until the shares to be delivered have been
listed or authorized
<PAGE>

to be listed on such exchange upon official notice of issuance, and (iv) until
all other legal matters in connection with the issuance and delivery of such
shares have been approved by the Company's counsel.

     6.   Nontransferability of Option.  This option is personal and no rights
          ----------------------------
granted hereunder may be transferred, assigned, pledged or hypothecated in any
way (whether by operation of law or otherwise) nor shall any such rights be
subject to execution, attachment or similar process.  Upon any attempt to
transfer, assign, pledge, hypothecate or otherwise dispose of this option or of
such rights contrary to the provisions hereof, or upon the levy of any
attachment or similar process upon this option or such rights, this option and
such rights shall, at the election of the Company, become null and void.

     7.   Proxy.  The Optionee hereby appoints Banyan Worldwide, a Massachusetts
          -----
corporation, and/or its designee(s) ("Banyan"), as the Optionee's attorney-in-
fact and proxy, with full power of substitution, for and in the Optionee's name,
to vote, express consent or disapproval, or otherwise act in such manner
(including pursuant to written consent) and upon such matters as Banyan or its
designee(s), proxy or substitute(s) shall, in its or their sole discretion, deem
proper with respect to any and all of the shares issued upon any exercise of
this option or issued in respect to such shares as a stock dividend, stock split
or otherwise (collectively, for purposes of Sections 7, 8 and 9 hereof, the
"Shares").  The proxy granted hereby shall be irrevocable and may be exercised
at any meeting or in respect of any written consent of stockholders.  This proxy
is coupled with an interest sufficient in law to support such proxy.  This proxy
shall remain in full force and effect and be enforceable against any donee,
transferee or assignee of the stock.  In addition to any other applicable
limitations pursuant to the terms of this option, the Optionee agrees not to
sell, assign, transfer, loan, tender, pledge, hypothecate, exchange, encumber or
otherwise dispose of, or issue an option or call with respect to, any of the
Shares, or impair such Shares, in each case unless, and as a condition precedent
thereto, the transferee of such Shares executes and delivers to Banyan an
agreement to be bound by the terms of this Section 7.  Any purported transfer in
violation of this Section 7 shall be null and void and shall not be recognized
by the Company or reflected on the stock records of the Company.  The Optionee
shall cause the Company to require any certificates representing any and all
Shares issued upon any exercise of this option to bear a legend referencing the
restrictions on transfer set for in this Section 7, which legend shall be
subject to the approval of Banyan.  Notwithstanding anything to the contrary in
the foregoing, the provisions of, including, without limitation, the proxy
appointed by, this Section 7 shall terminate upon the closing of the Company's
initial public offering, underwritten by a nationally recognized underwriter,
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "Securities Act").

     8.   Repurchase of Shares Upon Termination of Employment.  The following
          ---------------------------------------------------
repurchase provisions shall apply to any and all Shares;

          (a) Repurchase Rights.  If the Optionee for any reason whatsoever
              -----------------
(including without limitation death, disability, or voluntary or involuntary
termination) ceases to be employed by the Company or Banyan Worldwide, or
providing services on behalf of the Company or Banyan Worldwide, prior to the
date specified in Section 8(d) below for the
<PAGE>

expiration of these restrictions, then during the 90-day period following such
termination the Company may elect, by written notice delivered to the Optionee,
to repurchase all or any portion of the Shares, at a price per share equal to
the fair market value of such Shares as of the close of business on the date of
termination of the Optionee's employment. Such fair market value shall be
determined by mutual agreement of the Company and the Optionee. Failing such
agreement between the Optionee and the Company within 30 days of the date of the
Company's notice electing to repurchase such Shares, the fair market value of
such Shares shall be determined by three appraisers, one designated within five
days after the termination of said 30-day period by the Optionee or his or her
legal representatives (which appraiser shall not be the Optionee or his or her
legal representative), one within said period of five days by the Company (which
appraiser shall not be an officer, director or employee of the Company) and the
third within five days after said appointment last occurring by the two
appraisers so chosen. Successor appraisers, if any shall be required, shall be
appointed, within a reasonable time, as nearly as may be in the manner provided
as to the related original appointment. No appointment shall be deemed as having
been accomplished unless such appraiser shall have accepted in writing his
appointment as such within the time limited for his appointment. Notice of each
appointment of an appraiser shall be given promptly to the other parties in
interest. Any expenses relating to the appointment and service of an appraiser
shall be paid by the party appointing such appraiser or, in the case of the
appraiser appointed by the appraisers chosen by the Company and the Optionee,
shall be paid by the Company. Said appraisers shall proceed promptly to
determine the fair market value of said Share or Shares by agreement of any two
of the appraisers, which shall be conclusive upon all parties in interest in
such Shares. Promptly following such determination, the appraisers shall mail or
deliver such notice of such determination to the Optionee and the Company.

          (b) Repurchase Procedure.  Upon notice from the Company of exercise of
              --------------------
its rights under this Section 8 and determination of the purchase price for the
Shares so repurchased, the Optionee shall transfer the Shares or appropriate
part thereof to the Company against payment by the Company of the purchase price
therefor.  If upon the expiration of the 90-day period following the Optionee's
termination of employment the Company shall have failed to elect to repurchase
all of the Shares, the repurchase rights with respect to the Shares not so
elected to be repurchased imposed by this Section 8 shall terminate, and the
Optionee or his or her legal representatives may thereafter transfer such
Shares.  The Optionee or his or her legal representatives may in no event
transfer any Shares prior thereto, other than to the Company.

          (c) Failure of Optionee to Comply.  If the Optionee fails to comply
              -----------------------------
with any of the provisions of this Section 8, the Company, at its option and in
addition to its other remedies, may suspend the rights of the Optionee to vote
and to receive dividends on the Shares, or may refuse to register on its books
any transfer or change in the ownership of the Shares or in the right to vote
thereon, until the provisions of this Section 8 are complied with to the
satisfaction of the Company.

          (d) Expiration.  The restriction contained in this Section 8 shall
              ----------
expire upon the closing of the Company's initial public offering, underwritten
by a nationally recognized underwriter, pursuant to an effective registration
statement under the Securities Act (such expiration date shall be referred to
herein as the "Expiration Date").
<PAGE>

          (e) Safekeeping.  The Optionee acknowledges that the Company may, in
              -----------
its discretion, retain for safekeeping stock certificates representing all
Shares purchased hereunder by the Optionee.  The Optionee further acknowledges
that the Company may, to insure that the Optionee complies with the restriction
of this Section 8, continue to retain such stock certificates until the earlier
of the Expiration Date or the date of expiration of these repurchase rights
under Section 8(b) above.  At the time of any exercise of this option, in whole
or in part, the Optionee shall execute such further agreement as the Company may
require to implement the foregoing.

     9.   Right of First Refusal.
          ----------------------

          (a) General.  The Optionee shall not sell, assign, pledge, or in any
              -------
manner transfer any of the Shares or any right or interest therein, whether
voluntarily or by operation of law, or by gift or otherwise, except by a
transfer which meets the requirements of the provisions of this Section 9.

          (b) Restrictions on Transfer.  If at any time or from time to time the
              ------------------------
Optionee intends to sell or transfer any Shares to a third party, the Optionee
shall provide notice thereof to the Company prior to such transfer (which in the
case of a sale shall include a bona fide purchase agreement with a viable
purchaser).  The Company shall have an option for 30 days following the date of
receipt of the Optionee's notice to purchase such Shares on the terms upon which
the Shares were to be purchased by or transferred to the third party by the
Optionee.  If the Company does not exercise its right of first refusal under
this Section 9(b) with respect to such proposed sale or transfer within such 30-
day period, the Optionee shall be free to sell or transfer such Shares to the
third party identified in the Optionee's notice for a period of 45 days after
the expiration of the 30-day period following the date of receipt of the
Optionee's notice.  Such sale or transfer must be on terms no more favorable to
the recipient than those set forth in the Optionee's notice.  In no event may
Shares be sold or transferred to any then-current competitor of the Company.
Any transfer or sale of Shares by the Optionee will be conditional upon the
recipient acknowledging in writing the option set forth in this Section 9(b) and
the other restrictions to which the Shares are subject.

          (c) Failure of Optionee to Comply.  If the Optionee's notice in
              -----------------------------
respect of any Shares is not received by the Company as provided in Section 9(b)
above, or if the Optionee fails to comply with the provisions of Section 9(b)
above in respect of any such Shares in any other regard, the Company, at its
option and in addition to its other remedies, may suspend the rights to vote or
to receive dividends on said Shares, or may refuse to register on its books any
transfer or change in ownership of said Shares or in the right to vote thereon,
until the provisions of Section 9(b) are complied with to the satisfaction of
the Company; and if the required Optionee's notice is not received by the
Company after written demand by the Company, the Company may also independently
proceed as though a proper Optionee's notice has been received at the expiration
of ten days after mailing such demand, and, if the Company exercises its rights
under Section 9(b) with respect to said Shares or any of them, the Shares
specified shall be transferred accordingly.

          (d) Expiration.  The Company's right of first refusal contained in
              ----------
this Section 9 with respect to any sale or transfer of Shares shall expire upon
the Expiration Date.
<PAGE>

     10.  No Special Employment Rights.  Nothing contained in the Plan or this
          ----------------------------
option shall be construed or deemed by any person under any circumstances to
bind the Company to continue the employment of the Optionee for the period
within which this option may be exercised.

     11.  Rights as a Shareholder.  The Optionee shall have no rights as a
          -----------------------
shareholder with respect to any shares which may be purchased by exercise of
this option (including, without limitation, any rights to receive dividends or
non-cash distributions with respect to such shares) unless and until a
certificate representing such shares is duly issued and delivered to the
Optionee.  No adjustment shall be made for dividends or other rights for which
the record date is prior to the date such stock certificate is issued.

     12.  Adjustment Provisions.
          ---------------------

          (a) General.  In the event of a consolidation, merger or other
              -------
reorganization in which all of the outstanding shares of Common Stock are
exchanged for securities, cash or other property of any other corporation or
business entity (an "Acquisition") or in the event of a liquidation of the
Company, the Board of Directors of the Company or the board of directors of any
corporation assuming the obligations of the Company, may, in its discretion,
take any one or more of the following actions as to this option:  (i) provide
that this option shall be assumed, or a substantially equivalent option shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof) on such terms as the Board determines to be appropriate, (ii) upon
written notice to the Optionee, provide that if unexercised, this option will
terminate immediately prior to the consummation of such transaction unless
exercised by the Optionee within a specified period following the date of such
notice, (iii) in the event of an Acquisition under the terms of which holders of
the Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the Acquisition (the "Acquisition Price"),
make or provide for a cash payment to the Optionee equal to the difference
between (A) the Acquisition Price times the number of shares of Common Stock
subject to outstanding options (to the extent then exercisable at prices not in
excess of the Acquisition Price) and (B) the aggregate exercise price of all
such outstanding options in exchange for the termination of such options, and
(iv) provide that all or any outstanding options shall become exercisable or
realizable in full prior to the effective date of such Acquisition.

          (b) Board Authority to Make Adjustments.  Any adjustments under this
              -----------------------------------
Section 12 will be made by the Board of Directors, whose determination as to
what adjustments, if any, will be made and the extent thereof will be final,
binding and conclusive.  No fractional shares will be issued pursuant to this
option on account of any such adjustments.

     13.  Withholding Taxes.  The Company's obligation to deliver shares upon

          -----------------------------------
<PAGE>

          (a)   Representations.  The Optionee represents, warrants and
                ---------------
covenants that:

          (i)   Any shares purchased upon exercise of this option shall be
     acquired for the Optionee's account for investment only and not with a view
     to, or for sale in connection with, any distribution of the shares in
     violation of the Securities Act or any rule or regulation under the
     Securities Act.

          (ii)  The Optionee has had such opportunity as he or she has deemed
     adequate to obtain from representatives of the Company such information as
     is necessary to permit the Optionee to evaluate the merits and risks of his
     or her investment in the Company.

          (iii) The Optionee is able to bear the economic risk of holding
     shares acquired pursuant to the exercise of this option for an indefinite
     period.

          (iv)  The Optionee understands that (A) the shares acquired pursuant
     to the exercise of this option will not be registered under the Securities
     Act and are "restricted securities" within the meaning of Rule 144 under
     the Securities Act; (B) such shares cannot be sold, transferred or
     otherwise disposed of unless they are subsequently registered under the
     Securities Act or an exemption from registration is then available; (C) in
     any event, an exemption from registration under Rule 144 or otherwise under
     the Securities Act may not be available for at least two years and even
     then will not be available unless a public market then exists for the
     Common Stock, adequate information concerning the Company is then available
     to the public and other terms and conditions of Rule 144 are complied with;
     and (D) there is now no registration statement on file with the Securities
     and Exchange Commission with respect to any stock of the Company and the
     Company has no obligation or current intention to register any shares
     acquired pursuant to the exercise of this option under the Securities Act.

          (v)   The Optionee agrees that, if the Company offers for the first
     time any of its Common Stock for sale pursuant to a registration statement
     under the Securities Act, the Optionee will not, without the prior written
     consent of the Company, publicly offer, sell, contract to sell or otherwise
     dispose of, directly or indirectly, any shares purchased upon exercise of
     this option for a period of 180 days after the effective date of such
     registration statement.

By making payment upon exercise of this option, the Optionee shall be deemed to
have reaffirmed, as of the date of such payment, the representations made in
this Section 14.

          (b)   Legends on Stock Certificates.  All stock certificates
                -----------------------------
representing shares of Common Stock issued to the Optionee upon exercise of this
option shall have affixed thereto legends substantially in the following forms,
in addition to any other legends required by applicable state law:

     "The shares of stock represented by this certificate have not been
     registered under the Securities Act of 1933 and may not be transferred,
     sold or otherwise disposed of in the absence of an effective registration
     statement with respect to the shares evidenced by this
<PAGE>

     certificate, filed and made effective under the Securities Act of 1933, or
     an opinion of counsel satisfactory to the Company to the effect that
     registration under such Act is not required."

     "The shares of stock represented by this certificate are subject to certain
     restrictions on transfer and repurchase rights contained in an Option
     Agreement, a copy of which will be furnished upon request by the issuer."

To ensure compliance with the terms of this agreement, the Company may issue to
its transfer agent appropriate stop transfer instructions with respect to the
Shares.

     15.  Miscellaneous.
          -------------

          (a) The Board may amend, modify or terminate any outstanding option,
including substituting therefor another option of the same or a different type,
changing the date of exercise or realization, provided that the Optionee's
consent to such action shall be required unless the Board determines that the
action, taking into account any related action, would not materially and
adversely affect the Optionee.  The Board may at any time accelerate the time at
which all or any part of an Option may be exercised.

          (b) All notices under this option shall be mailed or delivered by hand
to the parties at their respective addresses set forth beneath their names below
or at such other address as may be designated in writing by either of the
parties to one another.

          (c) This option shall be governed by and construed in accordance with
the laws of the Commonwealth of Massachusetts.

           Notwithstanding anything to the contrary in this option or in the
Plan, this option will vest as to 100% of the then-unvested shares upon the
occurrence of a Change of Control (as defined herein). For the purposes of this
option, a "Change of Control" shall mean an event or occurrence set forth in any
one or more of clauses (i) through (iv) below (including an event or occurrence
that constitutes a Change in Control under one of such subsections but is
specifically exempted from another such subsection):

     (i)   the acquisition by an individual, entity or group (within the meaning
     of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as
     amended (the "Exchange Act")) (a "Person"), other than Banyan Worldwide or
     CBS Corporation, of beneficial ownership of any capital stock of the
     Company if, after such acquisition, such Person beneficially owns (within
     the meaning of Rule 13d-3 promulgated under the Exchange Act) 20% or more
     of either (A) the then-outstanding shares of common stock of the Company
     (the "Outstanding Company Common Stock") or (B) the combined voting power
     of the then-outstanding securities of the Company entitled to vote
     generally in the election of directors (the "Outstanding Company Voting
     Securities"); provided, however, that for purposes of this clause (i), the
                   --------
     following acquisitions shall not constitute a Change in Control: (I) any
     acquisition directly from the Company (excluding an acquisition pursuant to
     the exercise, conversion or exchange of any security exercisable for,
     convertible into or exchangeable for common stock or voting securities of
     the Company, unless the Person exercising, converting or exchanging such
     security acquired such security directly from the Company or an underwriter
     or agent of the Company), (II) any acquisition by the Company, (III) any
     acquisition by any employee benefit plan (or related trust) sponsored or
     maintained by the Company or any corporation controlled by the Company, or
     (IV) any acquisition by any corporation pursuant to a transaction which
     complies with clauses (A) and (B) of clause (iii) of this Section 3(a); or

     (ii) such time as the Continuing Directors (as defined below) do not
     constitute a majority of the Board (or, if applicable, the Board of
     Directors of a successor corporation to the Company), where the term
     "Continuing Director" means at any date a member of the  Board (A) who was
     a member of the Board on the date of the execution of this Agreement or (B)
     who was nominated or elected subsequent to such date by at least a majority
     of the directors who were Continuing Directors at the time of such
     nomination or election or whose election to the Board was recommended or
     endorsed by at least a majority of the directors who were Continuing
     Directors at the time of such nomination or election; provided, however,
                                                           --------  -------
     that there shall be excluded from this clause (B) any individual whose
     initial assumption of office occurred as a result of an actual or
     threatened election contest with respect to the election or removal of
     directors or other actual or threatened solicitation of proxies or
     consents, by or on behalf of a person other than the Board; or

     (iii) the consummation of a merger, consolidation, reorganization,
     recapitalization or statutory share exchange involving the Company or a
     sale or other disposition of all or substantially all of the assets of the
     Company (a "Business Combination"), unless, immediately following such
     Business Combination, each of the following two conditions is satisfied:
     (A) all or substantially all of the individuals and entities who were the
<PAGE>

     beneficial owners of the Outstanding Company Common Stock and Outstanding
     Company Voting Securities immediately prior to such Business Combination
     beneficially own, directly or indirectly, more than 50% of the then-
     outstanding shares of common stock and the combined voting power of the
     then-outstanding securities entitled to vote generally in the election of
     directors, respectively, of the resulting or acquiring corporation in such
     Business Combination (which shall include, without limitation, a
     corporation which as a result of such transaction owns the Company or
     substantially all of the Company's assets either directly or through one or
     more subsidiaries) (such resulting or acquiring corporation is referred to
     herein as the "Acquiring Corporation") in substantially the same
     proportions as their ownership, immediately prior to such Business
     Combination, of the Outstanding Company Common Stock and Outstanding
     Company Voting Securities, respectively; and (B) no Person (excluding the
     Acquiring Corporation or any employee benefit plan (or related trust)
     maintained or sponsored by the Company or by the Acquiring Corporation)
     beneficially owns, directly or indirectly, 20% or more of the then
     outstanding shares of common stock of the Acquiring Corporation, or of the
     combined voting power of the then-outstanding securities of such
     corporation entitled to vote generally in the election of directors (except
     to the extent that such ownership existed prior to the Business
     Combination); or

     (iv) approval by the stockholders of the Company of a complete liquidation
          or dissolution of the Company.


          (b)  Exercise Procedure.  Subject to the conditions set forth in this
               ------------------
Agreement, this option shall be exercised by the Optionee's delivery of written
notice of exercise to the Treasurer of the Company, specifying the number of
shares to be purchased and the purchase price to be paid therefor and
accompanied by payment in full in accordance with Section 4. Such exercise shall
be effective upon receipt by the Treasurer of the Company of such written notice
together with the required payment. The Optionee may purchase less than the
number of shares covered hereby, provided that no partial exercise of this
option may be for any fractional share or for fewer than ten whole shares.

          (c) Continuous Relationship with the Company Required.  This option
              -------------------------------------------------
may not be exercised unless the Optionee, at the time he or she exercises this
option, is, and has been at all times since the date of grant of this option, an
employee of either the Company or Banyan Worldwide, officer or director of, or
consultant or advisor to, the Company (an "Eligible Optionee").

          (d) Termination of Employment.  If the Optionee ceases to be employed
              -------------------------
by the Company for any reason (including without limitation death, disability,
or voluntary or involuntary termination), then the right to exercise this option
shall terminate 30 days after such cessation.

          (e) Early Exercise Alternative.  Notwithstanding the exercisability
              --------------------------
schedule set forth in paragraph (a), the Optionee may elect to exercise this
option as to the unvested shares (in addition to the vested shares) if
simultaneously with such exercise the Optionee enters into a Stock Restriction
Agreement with the Company in the form attached hereto as Exhibit A
                                                          ---------
(the "Stock Restriction Agreement"). The Stock Restriction Agreement provides
that the unvested shares shall be subject to a right of repurchase (the
"Purchase Option") in favor of the Company at the $8.50 exercise price (as
adjusted pursuant to the terms hereof) in the event that the Optionee ceases to
be employed by the Company.

     4.   Payment of Purchase Price.
          -------------------------
<PAGE>

          (a) Method of Payment.  Payment of the purchase price for shares
              -----------------
purchased upon exercise of this option shall be made by delivery of cash or a
check in an amount equal to the exercise price of such option or, with the prior
consent of the Company (which may be withheld in its sole discretion), by (A)
delivery of shares of Common Stock owned by the Optionee for at least six
months, valued at their fair market value, as determined in (b) below, (B)
delivery of a promissory note of the Optionee to the Company on terms determined
by the Board, (C) delivery of an irrevocable undertaking by a broker to deliver
promptly to the Company sufficient funds to pay the exercise price or delivery
of irrevocable instructions to a broker to deliver promptly to the Company cash
or a check sufficient to pay the exercise price, (D) payment of such other
lawful consideration as the Board may determine, or (E) any combination of the
foregoing.

          (b) Valuation of Shares or Other Non-Cash Consideration Tendered in
              ---------------------------------------------------------------
Payment of Purchase Price.  For the purposes hereof, the fair market value of
- -------------------------
any share of the Company's Common Stock or other non-cash consideration which
may be delivered to the Company in exercise of this option shall be determined
in good faith by the Board of Directors of the Company.

          (c) Delivery of Shares Tendered in Payment of Purchase Price.  If the
              --------------------------------------------------------
Optionee exercises this option by delivery of shares of Common Stock of the
Company, the certificate or certificates representing the shares of Common Stock
of the Company to be delivered shall be duly executed in blank by the Optionee
or shall be accompanied by a stock power duly executed in blank suitable for
purposes of transferring such shares to the Company.  Fractional shares of
Common Stock of the Company will not be accepted in payment of the purchase
price of shares acquired upon exercise of this option.

          (d) Restrictions on Use of Option Stock.  Notwithstanding the
              -----------------------------------
foregoing, no shares of Common Stock of the Company may be tendered in payment
of the purchase price of shares purchased upon exercise of this option if the
shares to be so tendered were acquired within six (6) months before the date of
such tender, through the exercise of an option granted under the Plan or any
other stock option or restricted stock plan of the Company.

     5.   Delivery of Shares; Compliance With Securities Laws, Etc.
          --------------------------------------------------------

          (a) General.  The Company shall, upon payment of the option price for
              -------
the number of shares purchased and paid for, make prompt delivery of such shares
to the Optionee, provided that if any law or regulation requires the Company to
take any action with respect to such shares before the issuance thereof, then
the date of delivery of such shares shall be extended for the period necessary
to complete such action.

          (b) Compliance With Securities Laws, Etc.  The Company will not be
              -------------------------------------
obligated to deliver any shares of Common Stock pursuant to the Plan or to
remove restriction from shares previously delivered under the Plan (i) until all
conditions of the option have been satisfied or removed, (ii) until, in the
opinion of the Company's counsel, all applicable federal and state laws and
regulation have been complied with, (iii) if the outstanding Stock is at the
time listed on any stock exchange, until the shares to be delivered have been
listed or authorized

to be listed on such exchange upon official notice of issuance, and (iv) until
all other legal matters in connection with the issuance and delivery of such
shares have been approved by the Company's counsel.

     6.   Nontransferability of Option.  This option is personal and no rights
          ----------------------------
granted hereunder may be transferred, assigned, pledged or hypothecated in any
way (whether by operation of law or otherwise) nor shall any such rights be
subject to execution, attachment or similar process.  Upon any attempt to
transfer, assign, pledge, hypothecate or otherwise dispose of this option or of
such rights contrary to the provisions hereof, or upon the levy of any
attachment or similar process upon this option or such rights, this option and
such rights shall, at the election of the Company, become null and void.

     7.   Proxy.  The Optionee hereby appoints Banyan Worldwide, a Massachusetts
          -----
corporation, and/or its designee(s) ("Banyan"), as the Optionee's attorney-in-
fact and proxy, with full power of substitution, for and in the Optionee's name,
to vote, express consent or disapproval, or otherwise act in such manner
(including pursuant to written consent) and upon such matters as Banyan or its
designee(s), proxy or substitute(s) shall, in its or their sole discretion, deem
proper with respect to any and all of the shares issued upon any exercise of
this option or issued in respect to such shares as a stock dividend, stock split
or otherwise (collectively, for purposes of Sections 7, 8 and 9 hereof, the
"Shares").  The proxy granted hereby shall be irrevocable and may be exercised
at any meeting or in respect of any written consent of stockholders.  This proxy
is coupled with an interest sufficient in law to support such proxy.  This proxy
shall remain in full force and effect and be enforceable against any donee,
transferee or assignee of the stock.  In addition to any other applicable
limitations pursuant to the terms of this option, the Optionee agrees not to
sell, assign, transfer, loan, tender, pledge, hypothecate, exchange, encumber or
otherwise dispose of, or issue an option or call with respect to, any of the
Shares, or impair such Shares, in each case unless, and as a condition precedent
thereto, the transferee of such Shares executes and delivers to Banyan an
agreement to be bound by the terms of this Section 7.  Any purported transfer in
violation of this Section 7 shall be null and void and shall not be recognized
by the Company or reflected on the stock records of the Company.  The Optionee
shall cause the Company to require any certificates representing any and all
Shares issued upon any exercise of this option to bear a legend referencing the
restrictions on transfer set for in this Section 7, which legend shall be
subject to the approval of Banyan.  Notwithstanding anything to the contrary in
the foregoing, the provisions of, including, without limitation, the proxy
appointed by, this Section 7 shall terminate upon the closing of the Company's
initial public offering, underwritten by a nationally recognized underwriter,
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "Securities Act").

     8.   Repurchase of Shares Upon Termination of Employment.  The following
          ---------------------------------------------------
repurchase provisions shall apply to any and all Shares;

          (a) Repurchase Rights.  If the Optionee for any reason whatsoever
              -----------------
(including without limitation death, disability, or voluntary or involuntary
termination) ceases to be employed by the Company or Banyan Worldwide, or
providing services on behalf of the Company or Banyan Worldwide, prior to the
date specified in Section 8(d) below for the
<PAGE>

expiration of these restrictions, then during the 90-day period following such
termination the Company may elect, by written notice delivered to the Optionee,
to repurchase all or any portion of the Shares, at a price per share equal to
the fair market value of such Shares as of the close of business on the date of
termination of the Optionee's employment. Such fair market value shall be
determined by mutual agreement of the Company and the Optionee. Failing such
agreement between the Optionee and the Company within 30 days of the date of the
Company's notice electing to repurchase such Shares, the fair market value of
such Shares shall be determined by three appraisers, one designated within five
days after the termination of said 30-day period by the Optionee or his or her
legal representatives (which appraiser shall not be the Optionee or his or her
legal representative), one within said period of five days by the Company (which
appraiser shall not be an officer, director or employee of the Company) and the
third within five days after said appointment last occurring by the two
appraisers so chosen. Successor appraisers, if any shall be required, shall be
appointed, within a reasonable time, as nearly as may be in the manner provided
as to the related original appointment. No appointment shall be deemed as having
been accomplished unless such appraiser shall have accepted in writing his
appointment as such within the time limited for his appointment. Notice of each
appointment of an appraiser shall be given promptly to the other parties in
interest. Any expenses relating to the appointment and service of an appraiser
shall be paid by the party appointing such appraiser or, in the case of the
appraiser appointed by the appraisers chosen by the Company and the Optionee,
shall be paid by the Company. Said appraisers shall proceed promptly to
determine the fair market value of said Share or Shares by agreement of any two
of the appraisers, which shall be conclusive upon all parties in interest in
such Shares. Promptly following such determination, the appraisers shall mail or
deliver such notice of such determination to the Optionee and the Company.

          (b) Repurchase Procedure.  Upon notice from the Company of exercise of
              --------------------
its rights under this Section 8 and determination of the purchase price for the
Shares so repurchased, the Optionee shall transfer the Shares or appropriate
part thereof to the Company against payment by the Company of the purchase price
therefor.  If upon the expiration of the 90-day period following the Optionee's
termination of employment the Company shall have failed to elect to repurchase
all of the Shares, the repurchase rights with respect to the Shares not so
elected to be repurchased imposed by this Section 8 shall terminate, and the
Optionee or his or her legal representatives may thereafter transfer such
Shares.  The Optionee or his or her legal representatives may in no event
transfer any Shares prior thereto, other than to the Company.

          (c) Failure of Optionee to Comply.  If the Optionee fails to comply
              -----------------------------
with any of the provisions of this Section 8, the Company, at its option and in
addition to its other remedies, may suspend the rights of the Optionee to vote
and to receive dividends on the Shares, or may refuse to register on its books
any transfer or change in the ownership of the Shares or in the right to vote
thereon, until the provisions of this Section 8 are complied with to the
satisfaction of the Company.

          (d) Expiration.  The restriction contained in this Section 8 shall
              ----------
expire upon the closing of the Company's initial public offering, underwritten
by a nationally recognized underwriter, pursuant to an effective registration
statement under the Securities Act (such expiration date shall be referred to
herein as the "Expiration Date").
<PAGE>

          (e) Safekeeping.  The Optionee acknowledges that the Company may, in
              -----------
its discretion, retain for safekeeping stock certificates representing all
Shares purchased hereunder by the Optionee.  The Optionee further acknowledges
that the Company may, to insure that the Optionee complies with the restriction
of this Section 8, continue to retain such stock certificates until the earlier
of the Expiration Date or the date of expiration of these repurchase rights
under Section 8(b) above.  At the time of any exercise of this option, in whole
or in part, the Optionee shall execute such further agreement as the Company may
require to implement the foregoing.

     9.   Right of First Refusal.
          ----------------------

          (a) General.  The Optionee shall not sell, assign, pledge, or in any
              -------
manner transfer any of the Shares or any right or interest therein, whether
voluntarily or by operation of law, or by gift or otherwise, except by a
transfer which meets the requirements of the provisions of this Section 9.

          (b) Restrictions on Transfer.  If at any time or from time to time the
              ------------------------
Optionee intends to sell or transfer any Shares to a third party, the Optionee
shall provide notice thereof to the Company prior to such transfer (which in the
case of a sale shall include a bona fide purchase agreement with a viable
purchaser).  The Company shall have an option for 30 days following the date of
receipt of the Optionee's notice to purchase such Shares on the terms upon which
the Shares were to be purchased by or transferred to the third party by the
Optionee.  If the Company does not exercise its right of first refusal under
this Section 9(b) with respect to such proposed sale or transfer within such 30-
day period, the Optionee shall be free to sell or transfer such Shares to the
third party identified in the Optionee's notice for a period of 45 days after
the expiration of the 30-day period following the date of receipt of the
Optionee's notice.  Such sale or transfer must be on terms no more favorable to
the recipient than those set forth in the Optionee's notice.  In no event may
Shares be sold or transferred to any then-current competitor of the Company.
Any transfer or sale of Shares by the Optionee will be conditional upon the
recipient acknowledging in writing the option set forth in this Section 9(b) and
the other restrictions to which the Shares are subject.

          (c) Failure of Optionee to Comply.  If the Optionee's notice in
              -----------------------------
respect of any Shares is not received by the Company as provided in Section 9(b)
above, or if the Optionee fails to comply with the provisions of Section 9(b)
above in respect of any such Shares in any other regard, the Company, at its
option and in addition to its other remedies, may suspend the rights to vote or
to receive dividends on said Shares, or may refuse to register on its books any
transfer or change in ownership of said Shares or in the right to vote thereon,
until the provisions of Section 9(b) are complied with to the satisfaction of
the Company; and if the required Optionee's notice is not received by the
Company after written demand by the Company, the Company may also independently
proceed as though a proper Optionee's notice has been received at the expiration
of ten days after mailing such demand, and, if the Company exercises its rights
under Section 9(b) with respect to said Shares or any of them, the Shares
specified shall be transferred accordingly.

          (d) Expiration.  The Company's right of first refusal contained in
              ----------
this Section 9 with respect to any sale or transfer of Shares shall expire upon
the Expiration Date.
<PAGE>

     10.  No Special Employment Rights.  Nothing contained in the Plan or this
          ----------------------------
option shall be construed or deemed by any person under any circumstances to
bind the Company to continue the employment of the Optionee for the period
within which this option may be exercised.

     11.  Rights as a Shareholder.  The Optionee shall have no rights as a
          -----------------------
shareholder with respect to any shares which may be purchased by exercise of
this option (including, without limitation, any rights to receive dividends or
non-cash distributions with respect to such shares) unless and until a
certificate representing such shares is duly issued and delivered to the
Optionee.  No adjustment shall be made for dividends or other rights for which
the record date is prior to the date such stock certificate is issued.

     12.  Adjustment Provisions.
          ---------------------

          (a) General.  In the event of a consolidation, merger or other
              -------
reorganization in which all of the outstanding shares of Common Stock are
exchanged for securities, cash or other property of any other corporation or
business entity (an "Acquisition") or in the event of a liquidation of the
Company, the Board of Directors of the Company or the board of directors of any
corporation assuming the obligations of the Company, may, in its discretion,
take any one or more of the following actions as to this option:  (i) provide
that this option shall be assumed, or a substantially equivalent option shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof) on such terms as the Board determines to be appropriate, (ii) upon
written notice to the Optionee, provide that if unexercised, this option will
terminate immediately prior to the consummation of such transaction unless
exercised by the Optionee within a specified period following the date of such
notice, (iii) in the event of an Acquisition under the terms of which holders of
the Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the Acquisition (the "Acquisition Price"),
make or provide for a cash payment to the Optionee equal to the difference
between (A) the Acquisition Price times the number of shares of Common Stock
subject to outstanding options (to the extent then exercisable at prices not in
excess of the Acquisition Price) and (B) the aggregate exercise price of all
such outstanding options in exchange for the termination of such options, and
(iv) provide that all or any outstanding options shall become exercisable or
realizable in full prior to the effective date of such Acquisition.

          (b) Board Authority to Make Adjustments.  Any adjustments under this
              -----------------------------------
Section 12 will be made by the Board of Directors, whose determination as to
what adjustments, if any, will be made and the extent thereof will be final,
binding and conclusive.  No fractional shares will be issued pursuant to this
option on account of any such adjustments.

     13.  Withholding Taxes.  The Company's obligation to deliver shares upon
          -----------------
the exercise of this option shall be subject to the Optionee's satisfaction of
all applicable federal, state and local income and employment tax withholding
requirements.

     14.  Investment Representations; Legends.
          -----------------------------------
<PAGE>

          (a)   Representations.  The Optionee represents, warrants and
                ---------------
covenants that:

          (i)   Any shares purchased upon exercise of this option shall be
     acquired for the Optionee's account for investment only and not with a view
     to, or for sale in connection with, any distribution of the shares in
     violation of the Securities Act or any rule or regulation under the
     Securities Act.

          (ii)  The Optionee has had such opportunity as he or she has deemed
     adequate to obtain from representatives of the Company such information as
     is necessary to permit the Optionee to evaluate the merits and risks of his
     or her investment in the Company.

          (iii) The Optionee is able to bear the economic risk of holding
     shares acquired pursuant to the exercise of this option for an indefinite
     period.

          (iv)  The Optionee understands that (A) the shares acquired pursuant
     to the exercise of this option will not be registered under the Securities
     Act and are "restricted securities" within the meaning of Rule 144 under
     the Securities Act; (B) such shares cannot be sold, transferred or
     otherwise disposed of unless they are subsequently registered under the
     Securities Act or an exemption from registration is then available; (C) in
     any event, an exemption from registration under Rule 144 or otherwise under
     the Securities Act may not be available for at least two years and even
     then will not be available unless a public market then exists for the
     Common Stock, adequate information concerning the Company is then available
     to the public and other terms and conditions of Rule 144 are complied with;
     and (D) there is now no registration statement on file with the Securities
     and Exchange Commission with respect to any stock of the Company and the
     Company has no obligation or current intention to register any shares
     acquired pursuant to the exercise of this option under the Securities Act.

          (v)   The Optionee agrees that, if the Company offers for the first
     time any of its Common Stock for sale pursuant to a registration statement
     under the Securities Act, the Optionee will not, without the prior written
     consent of the Company, publicly offer, sell, contract to sell or otherwise
     dispose of, directly or indirectly, any shares purchased upon exercise of
     this option for a period of 180 days after the effective date of such
     registration statement.

By making payment upon exercise of this option, the Optionee shall be deemed to
have reaffirmed, as of the date of such payment, the representations made in
this Section 14.

          (b)   Legends on Stock Certificates.  All stock certificates
                -----------------------------
representing shares of Common Stock issued to the Optionee upon exercise of this
option shall have affixed thereto legends substantially in the following forms,
in addition to any other legends required by applicable state law:

     "The shares of stock represented by this certificate have not been
     registered under the Securities Act of 1933 and may not be transferred,
     sold or otherwise disposed of in the absence of an effective registration
     statement with respect to the shares evidenced by this
<PAGE>

     certificate, filed and made effective under the Securities Act of 1933, or
     an opinion of counsel satisfactory to the Company to the effect that
     registration under such Act is not required."

     "The shares of stock represented by this certificate are subject to certain
     restrictions on transfer and repurchase rights contained in an Option
     Agreement, a copy of which will be furnished upon request by the issuer."

To ensure compliance with the terms of this agreement, the Company may issue to
its transfer agent appropriate stop transfer instructions with respect to the
Shares.

     15.  Miscellaneous.
          -------------

          (a) The Board may amend, modify or terminate any outstanding option,
including substituting therefor another option of the same or a different type,
changing the date of exercise or realization, provided that the Optionee's
consent to such action shall be required unless the Board determines that the
action, taking into account any related action, would not materially and
adversely affect the Optionee.  The Board may at any time accelerate the time at
which all or any part of an Option may be exercised.

          (b) All notices under this option shall be mailed or delivered by hand
to the parties at their respective addresses set forth beneath their names below
or at such other address as may be designated in writing by either of the
parties to one another.

          (c) This option shall be governed by and construed in accordance with
the laws of the Commonwealth of Massachusetts.
