                               PROSPECTUS SUMMARY
 
 
                                  Our Company
   
  VerticalNet owns and operates 33 industry-specific communities of commerce on
the Internet. These vertical trade communities are business-to-business Web
sites that act as comprehensive sources of information, interaction and
electronic commerce--the buying and selling of goods and services over the
Internet.     
   
  Each of our communities is individually branded, focuses on one business
sector and caters to individuals with similar professional interests. We design
each of our vertical trade communities to attract professionals responsible for
selecting and purchasing highly specialized industry related products and
services.     
   
  For example, our vertical trade community for the chemical industry, chemical
online (www.chemicalonline.com), serves the needs of buyers and suppliers
involved in the manufacturing and processing of chemicals.     
     
  Our communities combine:     
    
 . product           
  information       
 . requests for      
  proposals         
 . discussion forums 
 . electronic
  commerce
  opportunities
 . industry news
 . directories                           
 . classifieds                           
 . job listings                          
 . online professional education courses      
   
  We satisfy a developing market not currently being adequately served through
traditional channels, such as trade publishers, trade shows and trade
associations. We also believe that this market is not currently being served by
Internet companies, which tend to focus on the consumer and not on the
business-to-business market.     
   
  Our vertical trade communities exploit the interactive features and global
reach of the Internet, allowing buyers to research, source, contact and
purchase from suppliers.

 . continuing to rapidly develop new vertical trade communities;
   
 . forming alliances to enhance our distribution, marketing and technology;     
 
 . pursuing strategic acquisitions; and
 
 . expanding internationally.
   
  We currently generate the majority of our revenues from Internet advertising,
including the development of "storefronts." A storefront is a Web page posted
on one of our vertical trade communities that provides information on an
advertiser's products, links a visitor to the advertiser's Web site and
generates sales inquiries from interested visitors.     
   
  As our vertical trade communities expand, we expect to generate increasing
revenues from services such as:     
   
 . banner ads, which are advertisements that provide a link to the advertiser's
  Web page;     
 . education/career services;
   
 . sponsorships, which are sponsored newsletters and discussion forums;     
 . virtual trade shows;
   
 . electronic commerce;     
 . online industrial auctions; and
 . other special services.
   
  For the nine months ended September 30, 1998, we generated more than 98% of
our revenues from the sale of Internet advertising.     
   
  Internet advertising and electronic commerce are projected to experience
significant growth in the future:     
   
 . Internet advertising, according to Jupiter Communications, is projected to
  grow from $1.9 billion in 1998 to $7.7 billion in 2002;     
   
 . Business-to-business Internet advertising, according to Forrester Research,
  is projected to grow from $290 million in 1998 to $2.6 billion in 2002;     
   
 . Business-to-business electronic commerce, according to Forrester Research, is
  projected to grow from $17 billion in 1998 to $327 billion in 2002; and     
   
 . Online business auctions, according to Forrester Research, are projected to
  grow from $8.7 billion in 1998 to $52.6 billion in 2002.     
   
  We believe that industry professionals using our vertical trade communities
possess the demographic characteristics that are attractive to our advertisers.
As of December 31, 1998, we had more than 700 advertisers including, Asea Brown
Boveri, FMC Corporation, Hewlett-Packard, Koch Industries, Motorola,
Schlumberger and U.S. Filter.

into several marketing and distribution alliances including content
distribution alliances with Excite, Inc. and AltaVista and an
electronic commerce alliance with Junglee Corp.     
 
Acquisitions
   
  On September 1, 1998, we acquired RF Globalnet which operates
rfglobalnet.com, a vertical trade community focused on professionals in the
radio frequency and wireless communications industry. We also acquired
Informatrix on September 30, 1998. Informatrix operates
propertyandcasualty.com, a vertical trade community that caters to risk

  After the offering, Internet Capital Group will beneficially own 6,248,773
shares of common stock and warrants to purchase 119,656 shares of common stock,
which represent approximately 38.5% of the issued and outstanding shares of
common stock, at an assumed initial public offering price of $9.00 per share.
    
                               
                            Recent Developments     
   
Revenues (unaudited)     
   
  We generated revenues of $1.27 million for the three months ended December
31, 1998, giving us revenues of $3.13 million for the year ended December 31,
1998. For the three months ended December 31, 1998, we generated 95% of our
revenues from the sale of Internet advertising and 5% of our revenues from
electronic commerce. At December 31, 1998, we had deferred revenues of $2.10
million.     
   
  The revenue growth from $897,000 for the three months ended September 30,
1998 to $1.27 million for the three months ended December 31, 1998 is
attributable to the expansion of our sales and sales support personnel, the
acquisition of Informatrix and a full quarter of revenues for the acquisition
of RF Globalnet, and the addition of new revenue streams. We believe that the
higher revenue levels for the three months ended December 31, 1998 will not
translate into correspondingly lower net losses for that period. In
management's opinion, we have recorded all adjustments necessary to present
fairly the revenues for the three months ended December 31, 1998.     
   
Safety Online Acquisition     
   
  On January 13, 1999, we purchased the online business, operated as safety
online, from Coastal Video Communication Corp. for $260,000 in cash and a
$50,000 note which is payable without interest no earlier than 90 days from
such date. We also provided Coastal with an advertising commitment on our Web
site, which will be subsequently valued. This Web site is used by professionals
in the safety industry.

Prospectus Summary
<PAGE>
 
                                 RISK FACTORS
 
  You should carefully consider the following factors and other information in
this prospectus before deciding to invest in the shares of our common stock.
   
We Have Only Been Operating Our Business Since October 1995     
   
  We launched our first vertical trade community in October 1995. Accordingly,
we have a limited operating history upon which you may evaluate us. In
addition, our revenue model is evolving. Currently, our revenues are primarily
generated from the sale of advertising on our vertical trade communities. In
the future, we expect to generate revenue from multiple sources, including
electronic commerce and business services. We may not be able to sustain our
current revenues or successfully generate electronic commerce or business
services revenue. If we do not generate such revenue, our business, financial
condition and operating results will be materially adversely affected.     
          
We Anticipate We Will Incur Continued Losses For the Forseeable Future     
   
  To date, we have not been profitable. We may never be profitable or, if we
become profitable, we may be unable to sustain profitability. We have incurred
significant losses since inception. We reported a net loss of $8.3 million for
the nine months ended September 30, 1998. We expect to continue to incur
significant losses for the foreseeable future. As of September 30, 1998, our
accumulated deficit was $14.0 million. Our limited operating history makes
predicting our future operating results, including operating expenses,
difficult. Although our revenues have grown in recent periods, they may not
continue to grow or even continue at their current level.     
   
  Some of our expenses are fixed, including non-cancellable agreements,
equipment leases and real estate leases. If our revenues do not increase, we
may not be able to compensate by reducing expenses in a timely manner. In
addition, we plan to significantly increase our operating expenses to:     
   
 . launch additional vertical trade communities;     
   
 . increase our sales and marketing operations;     
   
 . enter into additional sponsorship agreements;     
   
 . broaden our customer support capabilities; and     
   
 . pursue marketing and distribution alliances.     
   
  Expenses may also increase due to the potential impact of goodwill and other
charges resulting from completed and future acquisitions.     
   
  Additionally, leading Web sites, browser providers and other Internet
distribution channels may begin to charge us to provide access to our products
and services. If any of these expenses are not accompanied by increased
revenues, our business, financial condition and operating results would be
materially adversely affected.     
   
Our Quarterly Results May Fluctuate     
   
  We expect that our quarterly operating results will fluctuate significantly
due to many factors, including:     
   
 . the seasonality of our revenues;     
   
 . the uncertain adoption of the Internet as an advertising medium;     
   
 . potential dependence on development of the electronic commerce market;     
 
                                       7
 
                                                                   Risk Factors
<PAGE>
 
   
 . intense competition;     
   
 . our dependence on content providers;     
   
 . license fees payable to content providers;     
   
 . uncertain acceptance of our Internet content;     
   
 . management of our growth; and     
   
 . risks associated with potential acquisitions.     
   
  All of these factors are described in more detail in the "Risk Factors"
below. Many of these factors are beyond our control.     
       
       
  Due to the limited history of businesses relying on the Internet as a
commercial medium, we believe that period-to-period comparisons of our
operating results are not meaningful. Additionally, if our operating results in
one or more quarters do not meet the securities analysts' or your expectations,
the price of our common stock could be materially adversely affected.
   
The Seasonality of Our Advertising Revenues and Usage Causes Our Overall
Revenues to Be Seasonal     
   
  Some of our revenue is seasonal. We experience seasonality in our advertising
revenue because advertising and media buying tends to be highest in the first
and fourth quarters of each calendar year. We also experience seasonality in
our traffic. User traffic on our vertical trade communities and the Web sites
of our partners is lower during the summer and year-end vacation and holiday
periods, when business usage of the Web and our services typically declines.
       
We Currently Rely Heavily on Advertising Revenues     
 
  We currently rely on revenues generated from the sale of advertising on our
vertical trade communities for substantially all of our revenues. To be
successful, we must continue to develop advertising and other sources of
revenues. Our ability to increase our advertising revenues may depend, among
other things, on many factors, including:
 
 . advertisers' acceptance of the Internet as a legitimate advertising medium;
 
 . the development of a large base of users on our vertical trade communities
  who possess demographic characteristics attractive to advertisers; and
   
 . the expansion of our sales force.     
   
  It is difficult to predict advertising revenues because a wide range of rates
are quoted and a variety of pricing models are offered by different vendors for
a variety of advertising services. For example, we currently base our
storefront advertising rates on a variety of factors including the maturity of
the particular vertical trade community, the number of storefronts and amount
of other advertising purchased and the length of the advertising contract. In
the future, advertising rates may be based on different parameters such as the
number of sales inquiries generated or visitors sent from our vertical trade
communities to advertisers' Web sites. Changes in industry pricing practices
could materially adversely affect our revenues in the future. Other factors
could also affect our revenues. For example, widespread use of "filter"
software programs that limit access to storefront advertising from the Internet
user's browser could reduce advertising on the Internet, which would materially
adversely affect our business, financial condition and operating results.     
   
Adoption of the Internet as an Advertising Medium is Uncertain     
 
  The growth of Internet advertising requires validation of the Internet as an
effective advertising medium. This validation has yet to fully occur.
Acceptance of the Internet among advertisers will also depend on growth in the
commercial use of the Internet. If widespread
 
                                       8
 
Risk Factors
<PAGE>
 
commercial use of the Internet does not develop, or if the Internet does not
develop as an effective and measurable medium for advertising, our business,
financial condition and operating results could be materially adversely
affected.
 
  No standards have been widely accepted to measure the effectiveness of
Internet advertising. If such standards do not develop, existing advertisers
may not continue their current levels of Internet advertising and advertisers
who are not currently advertising on the Internet may be reluctant to do so.
Our business, financial condition and operating results would be adversely
affected if the market for Internet advertising fails to develop or develops
slower than expected.
   
We May Not Develop Additional Revenue Sources     
   
  For the nine months ended September 30, 1998, approximately 2% of our
revenues were generated from electronic commerce. If we do not generate
increased revenue from electronic commerce, our business, financial condition
and operating results could be materially adversely affected. We plan to
generate revenues through revenue-sharing relationships with electronic
commerce partners in addition to selling advertising. To generate significant
electronic commerce revenues, we will have to continue to build or license an
electronic commerce platform in addition to our Junglee relationship.     
   
Our Long-Term Success Depends on the Development of the Electronic Commerce
Market     
   
  If electronic commerce does not grow or grows slower than expected, our
business will suffer. Our long-term success depends on widespread market-
acceptance of electronic commerce.
       
  A number of factors could prevent such acceptance, including the following:
       
 . electronic commerce is at an early stage and buyers may be unwilling to
  shift their purchasing from traditional vendors to online vendors;     
 
 . the necessary network infrastructure for substantial growth in usage of the
  Internet may not be adequately developed;
   
 . increased government regulation or taxation may adversely affect the
  viability of electronic commerce;     
   
 . insufficient availability of telecommunication services or changes in
  telecommunication services could result in slower response times; and     
   
 . adverse publicity and consumer concern about the security of electronic
  commerce transactions could discourage its acceptance and growth.     
          
There is Intense Competition for Internet Products and Services, Advertising
and Sales of Goods and Services     
   
  Competition for Internet products and services, advertising and electronic
commerce is intense. We expect that competition will continue to intensify.
Barriers to entry are minimal, and competitors can launch new Web sites at a
relatively low cost. We compete for a share of a customer's advertising budget
with online services and traditional off-line media, such as print and trade
associations. Although we believe that there may be opportunities for several
suppliers of products and services similar to ours, a single supplier may
dominate the market. Although to date we believe there are no companies with a
larger portfolio of vertical trade communities than ours, several companies
offer competitive vertical trade communities. We expect that additional
companies will offer competing vertical trade communities on a standalone or
portfolio basis.

                                                                   Risk Factors
<PAGE>
 
   
  Our competitors may develop Internet products or services that are superior
to, or have greater market acceptance than, our solutions. If we are unable to
compete successfully against our competitors, our business, financial condition
and operating results will be adversely affected.     
   
  Many of our competitors have greater brand recognition and greater financial,
marketing and other resources than ours. This may place us at a disadvantage in
responding to our competitors' pricing strategies, technological advances,
advertising campaigns, strategic partnerships and other initiatives.     
   
Concerns Regarding Security of Transactions and Transmitting Confidential
Information Over the Internet     
   
  We believe that concern regarding the security of confidential information
transmitted over the Internet, such as credit card numbers, prevents many
potential customers from engaging in online transactions. If we do not add
sufficient security features to future product releases, our products may not
gain market acceptance or there may be additional legal exposure to us. We have
included basic security features in some of our products to protect the privacy
and integrity of customer data, such as password requirements for access to
portions of our vertical trade communities. We do not currently use
authentication technology, which requires passwords and other information to
prevent unauthorized persons from accessing a customer's information, or
encryption, which transforms information into a "code" designed to be
unreadable by third parties, to protect confidential information such as credit
card numbers. However, we intend to license encryption technology to protect
confidential transaction data.     
   
  Despite the measures we have taken, our infrastructure is potentially
vulnerable to physical or electronic break-ins, viruses or similar problems. If
a person circumvents our security measures, he or she could misappropriate
proprietary information or cause interruptions in our operations. Security
breaches that result in access to confidential information could damage our
reputation and expose us to a risk of loss or liability. We may be required to
make significant investments and efforts to protect against or remedy security
breaches. Additionally, as electronic commerce becomes more prevalent (and
consequently becomes the focus of our development of direct marketing
products), our customers will become more concerned about security. If we do
not adequately address these concerns, this could materially adversely affect
our business, financial condition and operating results.     
   
Our Potential Dependence on Marketing and Distribution Alliances with Other
Internet Companies     
   
  We use marketing and distribution alliances with other Internet companies to
create traffic on our vertical trade communities and consequently, to generate
revenues. These marketing and distribution alliances allow us to link our
vertical trade communities to search engines such as those offered by Excite,
and on other Web sites such as AltaVista. The success of these relationships
depends on the amount of increased traffic we receive from the alliance
partners' Web sites. These arrangements may not generate the expected number of
new customers.     
   
  Our content distribution agreement with Excite has a term of three years and
is renewable for annual periods thereafter, but is terminable on 15 days prior
written notice at the end of any year. Our marketing and distribution agreement
with AltaVista has a term of one year, renews annually and may be terminated on
30 days notice prior     
 
                                       10

to renewal. If any of these agreements, or other agreements we enter into, are
terminated, the traffic on our vertical trade communities could decrease or
our advertising revenues derived from the sales of advertising on co-branded
pages could decrease.     
   
  We are interested in entering into additional partnerships with search
engine providers to increase traffic to our vertical trade communities but we
cannot assure you that we will be able to enter into any new partnerships. We
also cannot assure you that we will be able to renew successful marketing and
distribution alliance agreements. Additionally, we rely upon relationships
with several third parties that are not based upon a written agreement and may
be terminated at any time by either party.     
   
  If any of these relationships are terminated or if we are unable to further
develop and successfully administer our marketing and distribution alliances
and advertising campaigns, the traffic on our vertical trade communities could
decrease. Fewer visits could lead to less advertising revenue and fewer
purchases on our sites.     
   
Our Business Depends on the Growth of the Internet     
 
  Our market is new and rapidly evolving. Our business would be adversely
affected if Internet usage does not continue to grow. Internet usage may be
inhibited by a number of reasons, such as:
 
 . infrastructure;
 
 . security concerns;
 
 . inconsistent quality of service; and
 
 . lack of availability of cost-effective, high-speed service.
 
  If Internet usage grows, the Internet infrastructure may not be able to
support the demands placed on it by this growth or its performance or
reliability may decline. In addition, Web sites may from time to time
experience interruptions in their service as a result of outages and other
delays occurring throughout the Internet network infrastructure. If these
outages or delays frequently occur in the future, Internet usage, as well as
usage of our vertical trade communities, could be adversely affected.
   
Our Internet Content May Not Attract Users With Demographic Characteristics
Valuable to Our Advertisers     
   
  Our future success depends upon our ability to deliver compelling Internet
content about various industries that will attract users with demographic
characteristics valuable to our advertising customers. If we are unable to
develop Internet content that attracts a loyal user base possessing
demographic characteristics attractive to advertisers, it could have a
material adverse effect on our business, financial condition and operating
results. In addition, we may be unable to anticipate or respond to rapidly
changing buyer preferences to attract enough users to our vertical trade
communities. Internet users can freely navigate and instantly switch among a
large number of Web sites. Many of these Internet sites offer original
content. Thus, it is difficult for us to distinguish our content and attract
users.     
   
We Depend on Third Parties to Provide the Content For Our Vertical Trade
Communities     
   
  We rely on third parties, such as trade publications and news wires, to
provide the content for our vertical trade communities. It is critical to our
business that we maintain and build our existing relationships with content
providers. Many of our agreements with content providers are for initial terms
of one to two years. The content providers may choose not to renew the
agreements or may terminate the     
 
                                      11
 
                                                                   Risk Factors
<PAGE>
 
agreements early if we do not fulfill our contractual obligations, including
our payment obligations. If a significant number of content providers terminate
our agreements with them, it could result in decreased traffic on our vertical
trade communities and decreased advertising revenue. Because our agreements
with certain of our content providers are nonexclusive, a competitor could
offer content similar to or the same as ours.
   
The Licensee Fees We Pay to Content Providers May Increase     
   
   If licensing fees increase, it could materially adversely affect our
business, financial condition and operating results. License fees to content
providers may increase as competition for such content increases. Our content
providers may not enter into new agreements with us on similar terms as our
current agreements.     
   
The Development of the "VerticalNet" Brand and Our Vertical Trade Community
Brands is Important to Our Success     
   
  To be successful, we must establish and strengthen the brand awareness of the
"VerticalNet" brand as well as the brands associated with each individual
vertical trade community (e.g. wateronline.com). If our brand awareness is
weakened, it could decrease the attractiveness of our audiences to advertisers,
which could result in decreasing advertising revenues. We believe that brand
recognition will become more important in the future with the growing number of
Internet sites. Our brand awareness could be diluted, which could adversely
affect our business, finanical condition and operating results if users do not
perceive our products and services to be of high quality.     
   
Effectively Managing Our Growth May Be Difficult     
   
  We have grown and expect to continue to grow rapidly both by adding new
products and hiring new employees. This growth is likely to place a significant
strain on our resources and systems. To manage our growth, we must implement
systems and train and manage our employees.     
   
  Many of our senior management have only recently joined us. Of the eleven
employees listed in the management section of this prospectus, six have worked
for us less than one year. We cannot assure you that our management will be
able to effectively or successfully manage our growth.     
   
We May Not Be Able to Protect Our Proprietary Rights and We May Infringe the
Proprietary Rights of Others     
   
  Proprietary rights are important to our success and our competitive position.
We have applied for several trademarks, none of which has been issued to date.
Although we seek to protect our proprietary rights, our actions may be
inadequate to protect any trademarks and other proprietary rights or to prevent
others from claiming violations of their trademarks and other proprietary
rights. We currently have two pending trademark applications. Generally, our
domain names for our vertical trade communities are not protectible as
trademarks because they are too generic. In addition, effective copyright and
trademark protection may be unenforceable or limited in certain countries, and
the global nature of the Internet makes it impossible to control the ultimate
destination of our work. We also license content from third parties and it is
possible that we could become subject to infringement actions based upon the
content licensed from those third parties. We generally obtain representations
as to the origin and ownership     
 
                                       12
 
Risk Factors
<PAGE>
 
of such licensed content; however, this may not adequately protect us. Any of
these claims, with or without merit, could subject us to costly litigation and
the diversion of our technical and management personnel.
   
We May Not Be Able to Acquire or Maintain Effective Web Addresses     
   
  We currently hold various Internet Web addresses relating to our brand.
These Web addresses include wateronline.com, wirelessdesignonline.com,
pollutiononline.com and other Web addresses. We may not be able to prevent
third parties from acquiring Web addresses that are similar to our addresses,
which could materially adversely affect our business, financial condition and
operating results. The acquisition and maintenance of Web addresses generally
is regulated by governmental agencies and their designees. For example, in the
United States, the National Science Foundation has appointed Network
Solutions, Inc. as the exclusive registrar for the ".com," ".net" and ".org"
generic top-level addresses. The regulation of Web addresses in the United
States and in foreign countries is subject to change. As a result, we may not
be able to acquire or maintain relevant Web addresses in all countries where
we conduct business. Furthermore, the relationship between regulations
governing such addresses and laws protecting trademarks is unclear.     
   
Our Acquisition Strategy Has Certain Risks     
       
          
  Our acquisition strategy is subject to the following risks:     
 
 . we may not be able to identify additional suitable acquisition candidates
  available for sale at reasonable prices;
   
 . we may not be able to consummate any acquisition or successfully integrate
  services, products and personnel of any acquisition into our operations;
      
 . acquisitions may cause a disruption in our ongoing business, distract our
  management and other resources and make it difficult to maintain our
  standards, controls and procedures in acquisitions;
 
 . we may acquire companies in markets in which we have little experience; and
 
 . we may be required to incur debt or issue equity securities, which may be
  dilutive to existing shareholders, to pay for acquisitions.
   
  Our acquisitions may not result in any return on our investment and we may
lose our entire investment.     
   
  We have made and plan to continue to make investments in complementary
companies, technologies and assets. Recently we acquired Informatrix and RF
Globalnet. These companies are in an early stage of development and we expect
them to incur substantial losses.     
   
We May Be Subject to Legal Liability for Publishing or Distributing Content
Over the Internet     
   
  We may be subject to legal claims relating to the content in our vertical
trade communities, or the downloading and distribution of such content. For
example, persons may bring claims against us if material that is inappropriate
for viewing by young children can be accessed from our vertical trade
communities. Claims could also involve matters such as defamation, invasion of
privacy, and copyright infringement. Providers of Internet products and
services have been sued in the past, sometimes successfully, based on the
content of material. In addition, some of the content provided on our vertical
trade communities is drawn from data compiled by other parties, including
governmental and commercial sources, and we re-key the data. This data may
have errors. If our content is improperly used or if we supply     
 
                                      13
 
                                                                   Risk Factors
<PAGE>
 
   
incorrect information, it could result in unexpected liability. Our insurance
may not cover claims of this type, or may not provide sufficient coverage. Our
business, financial condition and operating results could suffer a material
adverse effect if costs resulting from these claims are not covered by our
insurance or exceed our coverage.     
   
Risk of Failure of Our Computer and Communications Hardware Systems Increases
Without Redundant Facilities     
   
  Our business depends on the efficient and uninterrupted operation of our
computer and communications hardware systems. Any system interruptions that
cause our vertical trade communities to be unavailable to Web browsers may
reduce the attractiveness of our vertical trade communities to advertisers and
could materially adversely affect our business, financial condition and
operating results. We maintain most of our computer systems in two Web-hosting
facilities in New Jersey. Interruptions could result from natural disasters as
well as power loss, telecommunications failure and similar events.     
   
Capacity Constraints on Our Technology, Transaction Processing System and
Network Hardware and Software May Be Difficult to Project     
   
  As traffic in our vertical trade communities continues to increase, we must
expand and upgrade our technology, transaction processing systems and network
hardware and software. We may not be able to accurately project the rate of
increase in our vertical trade communities. In addition, we may not be able to
expand and upgrade our systems and network hardware and software capabilities
to accommodate increased use of our vertical trade communities. If we do not
appropriately upgrade our systems and network hardware and software, our
business, financial condition and operating results will be materially
adversely affected.     
   
Our Market is Characterized by Rapid Technological Change     
   
  Our market is characterized by rapid technological change and frequent new
product announcements. Significant technological changes could render our
existing vertical trade community technology obsolete. If we are unable to
successfully respond to these developments or do not respond in a cost-
effective way, our business, financial condition and operating results will be
materially adversely affected. To be successful, we must adapt to our rapidly
changing market by continually improving the responsiveness, services and
features of our vertical trade communities and by developing new features to
meet customer needs. Our success will depend, in part, on our ability to
license leading technologies useful in our business, enhance our existing
services and develop new services and technology that address the needs of our
customers. We will also need to respond to technological advances and emerging
industry standards in a cost-effective and timely basis.     
   
Our Success is Dependent on Our Key Personnel     
   
  We believe that our success will depend on continued employment of our senior
management team and key technical personnel. If one or more members of our
senior management team were unable or unwilling to continue in their present
positions, our business, financial condition and operating results could be
materially adversely affected. Most of our senior management do not have
employment agreements. We carry key person life insurance on certain, but not
on all, of our senior management personnel.     
 
  Our success also depends on having a highly trained sales force and telesales
group. Our telesales group was formed recently. We will need to continue to
hire additional personnel as our business grows. A shortage in the number of
trained salespeople could limit our ability to increase sales in our existing
 
                                       14

<PAGE>
 
vertical trade communities and to sell as we launch new vertical trade
communities.
 
  We plan to expand our employee base to manage our anticipated growth.
Competition for personnel, particularly for employees with technical
expertise, is intense. Our business, financial condition and operating results
will be materially adversely affected if we cannot hire and retain suitable
personnel.
   
Our Systems May Not Be Year 2000 Compliant     
 
  The Year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. In other words,
date-sensitive software may recognize a date using "00" as the year 1900
rather than the year 2000. This could result in system failures or
miscalculations causing disruptions of operations, including, among others, a
temporary inability to process transactions, send invoices or engage in
similar normal business activities.
   
  We may realize exposure and risk if the systems on which we are dependent to
conduct our operations are not Year 2000 compliant. Our potential areas of
exposure include products purchased from third parties, computers, software,
telephone systems and other equipment used internally. We are currently in the
process of analyzing whether our systems are Year 2000 compliant. We expect to
resolve Year 2000 compliance issues primarily through normal upgrades of our
software or by replacing existing software with Year 2000 compliant
applications. The cost of these upgrades or replacements is included in our
capital expenditure budget and is not expected to be material to our financial
position or results of operations. However, we cannot assure you that such
upgrades and replacements can be completed on schedule or within estimated
costs or will successfully address our Year 2000 compliance issues.     
 
  In addition, we are currently conducting an analysis to determine the extent
to which key distributors, vendors and suppliers have Year 2000 issues. If
they are not yet Year 2000 compliant, we are asking them to provide a
description of their plans to become so.
   
  In the event that our production and operational facilities that support our
Web sites are not Year 2000 compliant, small portions of our Web sites may
become unavailable. Our review of our systems has shown that there is no
single application that would make our Web sites totally unavailable and we
believe that we can quickly address any difficulties that may arise.     
   
  In the event that our Web hosting facilities are not Year 2000 compliant,
our production Web sites would be unavailable and we would not be able to
deliver services to our users.     
   
If our present efforts to address the Year 2000 compliance issues are not
successful, or if distributors, suppliers and other third parties with which
we conduct business do not successfully address such issues, our business,
operating results and financial position could be materially and adversely
affected.     
          
The Offering Will Benefit Our Current Shareholders     
   
  Our current shareholders, including members of management, will recognize
significant benefits from the offering. These benefits include the creation of
a public market for our common stock which will afford existing stockholders
the ability to liquidate their investments, subject, in certain cases, to
volume limitations and other limitations and restrictions upon the sale of the
common stock, including any applicable lock-up arrangements. The excess of
market value of the publicly traded shares over amounts paid for common stock,
including common stock issuable upon conversion of the convertible preferred
stock, by our executive officers and directors is     
 
                                      15
 
                                                                   Risk Factors
<PAGE>
 
   
approximately $11.1 million, or $9.00 per share. In addition, the excess of the
assumed initial public offering price over the aggregate exercise price of
options and warrants held by our executive officers and directors is
approximately $9.0 million, or $6.97 per share.     
   
The Interests of Our Controlling Shareholder May Conflict With Our Interests.
       
  Internet Capital Group will own 6,248,773 shares of common stock after the
conversion of their preferred stock and convertible notes in the offering at an
assumed initial public offering price of $9.00 per share. Internet Capital
Group also owns warrants to purchase 119,656 shares of common stock. Based on
its ownership of common stock and warrants after the offering, Internet Capital
Group will beneficially own 38.5% of the common stock and will have two
representatives on our board of directors.     
   
As a result of its stock ownership and board representation, Internet Capital
Group will be in a position to affect corporate actions such as mergers or
takeover attempts in a manner that could conflict with the interests of our
public shareholders.     
   
Shares Eligible for Future Sale By Our Current Shareholders May Adversely
Affect Our Stock Price     
   
  If our shareholders sell substantial amounts of our common stock, including
shares issued upon the exercise of outstanding options and warrants, in the
public market following the offering, then the market price of our common stock
could fall. Restrictions under the securities laws and certain lock-up
agreements limit the number of shares of common stock available for sale in the
public market. The holders of 1,305,468 shares of common stock, 7,805,667
shares of convertible preferred stock that will automatically convert to
9,307,495 shares of common stock before the offering and warrants and options
exercisable into an aggregate of 462,074 shares of common stock have agreed not
to sell any such securities for 180 days after the offering without the prior
written consent of Lehman Brothers. In addition, the holders of the convertible
notes that will automatically convert into 555,556 shares of common stock,
assuming an initial public offering price of $9.00, have also agreed to such
restrictions. However, Lehman Brothers may, in its sole discretion, release all
or any portion of the securities subject to such lock-up agreements.     
   
  The holders of 7,805,667 shares of preferred stock that will automatically
convert to 9,307,495 shares of common stock prior to the offering and warrants
to purchase 235,871 shares of common stock have demand and piggy-back
registration rights. In addition, the holders of the convertible notes that
will automatically convert into 555,556 shares of common stock, assuming an
initial public offering price of $9.00 per share, have similar registration
rights. The exercise of such rights could adversely affect the market price of
our common stock. We also may shortly file a registration statement to register
all shares of common stock under our stock option plans. After such
registration statement is effective, shares issued upon exercise of stock
options will be eligible for resale in the public market without restriction.
       
Anti-Takeover Provisions and Our Right to Issue Preferred Stock Could Make a
Third-Party Acquisition of Us Difficult     
   
  VerticalNet is a Pennsylvania corporation. Anti-takeover provisions of
Pennsylvania law could make it more difficult for a third party to acquire
control of us, even if such change in control would be beneficial to
shareholders. Our articles of incorporation provide that our board of directors
may issue preferred stock without     
 
                                       16
 
Risk Factors
<PAGE>
 
shareholder approval. In addition, our bylaws provide for a classified board,
with each board member serving a staggered three year term. The issuance of
preferred stock and the existence of a classified board could make it more
difficult for a third-party to acquire us.
   
Our Common Stock Has Never Been Publicly Traded     
 
  There has not been a public market for our common stock. We cannot predict
the extent to which a trading market will develop or how liquid that market
might become. The initial public offering price will be determined by
negotiations between representatives of the underwriters and us and may not be
indicative of prices that will prevail in the trading market.
   
Our Common Stock Price is Likely to Be Highly Volatile     
   
  The market price of our common stock is likely to be highly volatile as the
stock market in general, and the market for Internet-related and technology
companies in particular, has been highly volatile. Investors may not be able
to resell their shares of our common stock following periods of volatility
because of the market's adverse reaction to such volatility. The trading
prices of many technology and Internet-related companies' stocks have reached
historical highs within the last 52 weeks and have reflected relative
valuations substantially above historical levels. During the same period, such
companies' stocks have also been highly volatile and have recorded lows well
below such historical highs. We cannot assure you that our stock will trade at
the same levels of other Internet stocks or that Internet stocks in general
will sustain their current market prices.     
   
  Factors that could cause such volatility may include, among other things:
    
 . actual or anticipated variations in quarterly operating results;
 
 . announcements of technological innovations;
 
 . new sales formats or new products or services;
 
 . changes in financial estimates by securities analysts;
 
 . conditions or trends in the Internet industry;
 
 . changes in the market valuations of other Internet companies;
 
 . announcements by us or our competitors of significant acquisitions,
  strategic partnerships or joint ventures;
 
 . capital commitments;
 
 . additions or departures of key personnel; and
 
 . sales of common stock.
 
  Many of these factors are beyond our control. These factors may materially
adversely affect the market price of our common stock, regardless of our
operating performance.

<PAGE>
 
                                USE OF PROCEEDS
   
  We estimate the net proceeds from the offering to be approximately $28.3
million or $32.7 million if the underwriters' exercise their over-allotment
option in full, assuming an initial public offering price of $9.00 per share
and after deducting estimated underwriting discounts and commissions and
expenses of the offering.     
   
  We expect to use the net proceeds from the offering to repay the debt
described below for investments in existing and future vertical trade
communities and for general corporate purposes. A portion of the net proceeds
may be used for consummation of strategic acquisitions. Although we are not
contemplating any specific acquisitions at this time, we expect that
acquisition candidates would be operators of vertical trade communities or
businesses with complementary technologies. We expect to use $2.0 million of
the net proceeds to repay a note issued to Progress Bank. This note bears
interest at the prime rate plus 1.5%. As of the date of this prospectus, we
cannot specify with certainty all of the particular uses for the remaining net
proceeds we will have upon completion of the offering. Accordingly, our
management will have broad discretion in the application of the net proceeds.
    
  Pending such uses, we intend to invest the net proceeds in interest-bearing,
investment-grade instruments, certificates of deposit, or direct or guaranteed
obligations of the United States.
 
                                DIVIDEND POLICY
   
  We have never declared or paid any dividends on our common stock. We do not
anticipate paying any cash dividends in the foreseeable future. We currently
intend to retain future earnings, if any, to finance operations and the
expansion of our business. Any future determination to pay cash dividends will
be at the discretion of the board of directors and will be dependent upon our
financial condition, operating results, capital requirements and such other
factors as the board of directors deems relevant.

                                    DILUTION
   
  As of September 30, 1998, our net tangible book value on a pro forma basis
giving effect to the $5.0 million in convertible notes that convert into common
stock upon the consummation of the offering based on an issued initial public
offering price of $9.00 per share and the conversion of our convertible
preferred stock was $7.0 million or $0.55 per share of common stock. "Net
tangible book value" per share represents the amount of our total tangible
assets reduced by the amount of our total liabilities, divided by the number of
shares of common stock outstanding. As of September 30, 1998, our net tangible
book value, on a pro forma basis as adjusted for the sale of the 3,500,000
shares offered in the offering and application of the net proceeds from such
sale of $28.3 million (based on an assumed initial public offering price of
$9.00 per share and after deducting the underwriting discounts and commissions
and other estimated offering expenses), would have been approximately $2.15 per
share. This represents an immediate increase of $1.60 per share to existing
shareholders and an immediate dilution of $6.85 per share to new investors. The
following table illustrates this per share dilution:

                            SELECTED FINANCIAL DATA
   
  We derived the selected historical and pro forma financial data presented
below from our historical and pro forma financial statements and related notes
included in another part of this prospectus. You should read the selected
financial data together with our historical and pro forma financial statements
and the section of the prospectus entitled "Management's Discussion and
Analysis of Financial Condition and Results of Operations."     
   
  KPMG LLP, independent certified public accountants, audited our historical
financial statements for the period from July 28, 1995 (inception) to December
31, 1995, for the years ended December 31, 1996 and December 31, 1997 and for
the nine months ended September 30, 1998. Their report appears in another part
of this prospectus. Our historical financial statements for the nine months
ended September 30, 1997 are unaudited, and in our opinion include all
adjustments, consisting of normal adjustments, necessary for a fair
presentation of the results for the unaudited period. You should not rely on
interim results as being indicative of results we may expect for the full year.
       
  We prepared the unaudited pro forma financial information for the year ended
December 31, 1997 and for the nine months ended September 30, 1998 by combining
the historical results of the two companies we acquired, RF Globalnet and
Informatrix, with our historical results using the purchase method of
accounting. This is described in the notes accompanying the information below.
We have presented this information to give you a better picture of what our
business might have looked like if we had owned RF Globalnet since January 1,
1997 and Informatrix since October 15, 1997 (inception). These companies may
have performed differently if they had actually been combined with our
operations. You should not rely on the unaudited pro forma information as being
indicative of the historical results that we would have had or the future
results that we will experience after the acquisitions.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
   
  The following discussion of our financial condition and results of
operations should be read together with the financial statements and the
related notes included in another part of this prospectus and which are deemed
to be incorporated into this section. This discussion contains forward-looking
statements that involve risks and uncertainties. Our actual results may differ
materially from those anticipated in those forward-looking statements as a
result of certain factors, including but not limited to, those set forth under
and included in other portions of this prospectus.     
   
  We own and operate 33 vertical trade communities. From our founding and
incorporation on July 28, 1995 to October 1995, our principal operating
activities consisted primarily of recruiting employees, performing product and
technology development, raising capital and engaging in marketing activities.
       
   Advertising revenues and Web site development fees contributed most of the
revenues for the period from July 28, 1995 to December 31, 1995 (the
"Inception Period") and in the years ended December 31, 1996 and December 31,
1997. Currently, most of our revenues are generated from selling
advertisements to industry suppliers in our vertical trade communities.     
       
       
          
  We sell storefront and banner advertising and event sponsorships on our
vertical trade communities. The duration of a storefront advertisement is
typically for a period of one year, while banner advertisements are typically
for a period of three months. All advertising revenues are recognized ratably
in the period in which the advertisement is displayed, provided that the
collection is reasonably assured. As of September 30, 1998, we had
approximately $1.5 million of deferred revenue. We also generate revenues from
career services, education and electronic commerce, specifically the sale of
books and third party software for which we receive a transaction fee.     
   
  Our relationship with Junglee allows us to sell to our visitors books,
software, travel bookings and other goods offered by third party Web sites. We
receive a portion of the revenue from the products sold on our "store," which
is operated for us by Junglee. This type of revenue sharing or commission
sharing relationship is typical of electronic commerce transactions and
relationships on the Internet.     
   
  We plan to expand our electronic commerce relationships to include:     
    
 . selling goods and services promoted on our advertisers' storefronts;     
    
 . selling goods and services from our owned and operated virtual store; and
          
 . auctioning goods posted on our Web sites by inventory-liquidators.     
   
  We expect to receive either a fee per transaction, a percentage of sales
revenue or some other minimum guaranteed payment.     
       
       
  We incurred net losses of approximately $211,000 for the Inception Period,
$709,000 for the year ended December 31, 1996, $4.8 million for the year ended
December 31, 1997, and $8.3 million for the nine months ended September 30,
1998 on an actual basis and $9.8 million for the nine months ended September
30, 1998 on a pro forma basis. At September 30, 1998, we had an accumulated
deficit of $14.0 million. The net

losses and accumulated deficit resulted from our lack of substantial revenues,
the costs of the significant infrastructure and other costs incurred for the
development and initial rollout of our vertical trade communities. Because of
our aggressive expansion plans, we expect to incur significant operating losses
for the foreseeable future. Although we have experienced revenue growth in
recent periods, such growth may not be sustainable and, therefore, these recent
periods should not be considered indicative of future performance. We may never
achieve significant revenues or profitability, or if we achieve significant
revenues they may not be sustained.     
 
Results of Operations
 
 Nine Months Ended September 30, 1997 and September 30, 1998
   
  Revenues. Revenues increased from $551,000 for the nine months ended
September 30, 1997 to $1.9 million for the nine months ended September 30,
1998. The increase in revenues was due primarily to an increase in the number
of advertisers as a result of our marketing efforts and the increase in the
number of vertical trade communities from 16 as of September 30, 1997 to 29 as
of September 30, 1998. Advertising revenues, including the development of the
storefronts, accounted for the majority of revenues for the periods ended
September 30, 1997 and September 30, 1998. At September 30, 1998, we had
deferred revenues of $1.5 million. We expect that advertising revenue will
continue to account for a substantial share of revenues for the foreseeable
future.     
   
  Editorial and Operational Expenses. Editorial and operational expenses
primarily consist of Internet connection charges, cost of acquired content,
depreciation, salaries and benefits of operating and editorial personnel and
other related operating costs. These expenses increased from $674,000 for the
nine months ended September 30, 1997 to $2.1 million for the nine months ended
September 30, 1998. For these periods, expenses increased by $7,000 for
Internet connection charges, $69,000 for cost of acquired content, $102,000 for
depreciation, $1.0 million for salaries and benefits of operating and editorial
personnel and $200,000 for other related operating costs. The increases were
primarily related to the increased number of personnel and amount of equipment
required to maintain and operate our increased number of vertical trade
communities.     
   
  Product Development Expenses. Product development expenses consist primarily
of salaries and benefits, consulting expenses and related equipment. These
costs increased from $451,000 as of September 30, 1997 to $798,000 for the nine
months ended September 30, 1998. For these periods, expenses increased by
$214,000 for salaries and benefit costs and by $133,000 for consulting and
equipment costs. This increase in expenses was due to increased staffing and
the costs of enhancing the features, content and services of our vertical trade
communities, as well as increasing the overall number of trade communities. To
date, we have charged to expense all of the product development costs when such
costs have been incurred. We believe that continued investment in product
development is critical to attaining our goals, and therefore expect product
development expenses to increase significantly.     
   
  Sales and Marketing Expenses. Sales and marketing expenses consist primarily
of salaries and commissions for sales and marketing personnel, advertising, and
travel and entertainment, including costs of attending trade shows. These
expenses increased from $1.3 million for the nine months ended September 30,
1997 to $4.4 million for the nine months ended September 30, 1998. For these
periods, expenses increased by $1.6 million for

advertising, $1.1 million for salary, commissions and benefits, and $464,000
for travel and entertainment expenses, including costs of attending trade
shows. This was primarily due to increasing the number of sales and marketing
personnel, increasing sales commissions and increased expenses related to
promoting our vertical trade communities. We expect these expenses will
continue to grow significantly, as we pursue an aggressive growth strategy and
hire additional sales/marketing personnel.     
   
  General and Administrative Expenses.  General and administrative expenses
consist primarily of salaries and related costs for our executive,
administrative, finance, human resources and business development personnel,
as well as support services and professional service fees. These expenses
increased from $891,000 for the nine months ended September 30, 1997 to $2.9
million for the nine months ended September 30, 1998. For these periods,
expenses increased by $1.2 million for general and administrative personnel,
$110,000 for depreciation, $359,000 for professional fees, $250,000 for
facility costs and $6,000 for other general and administrative costs. The
increase was primarily due to increases in the number of personnel to support
and grow our business. We expect these expenses to grow as additional
personnel are hired and additional expenses are incurred. These expenses
relate to growing our business and operating as a public company.     
       
  Interest, Net. Interest income net of expense includes income from our cash
and cash equivalents and from investments and expenses related to our
financing obligations. Interest income net of interest expense increased from
an expense of $29,000 for the nine months ended September 30, 1997 to income
of $15,000 for the nine months ended September 30, 1998. The increase was
primarily due to a higher investment balance as a result of our sale of
preferred stock, which was partially offset by increased interest expense due
to borrowings on our line of credit, and increased amounts of capital lease
obligations in May and June of 1998. Currently, we invest our cash balances in
money market funds.
 
 Inception Period and Years ended December 31, 1996 and December 31, 1997
   
  Revenues. Revenues were $16,000 for the Inception Period, $285,000 for the
year ended December 31, 1996 and $792,000 for the year ended December 31,
1997. The increases in advertising revenues were due to an increasing number
of advertisers on our vertical trade communities and an increase in the number
of vertical trade communities.     
          
  Editorial and Operational Expenses.  Editorial and operational expenses were
$24,000 for the Inception Period, $214,000 for the year ended December 31,
1996 and $1.1 million for the year ended December 31, 1997. From the Inception
Period to the year ended December 31, 1996, expenses increased by $21,000 for
Internet connection charges, $1,000 for cost of acquired content, $28,000 for
depreciation, $137,000 for salaries and benefits of operating and editorial
personnel and $3,000 for other related operating costs. From the year ended
December 31, 1996 to the year ended December 31, 1997, expenses increased by
$60,000 for Internet connection charges, $46,000 for cost of acquired content,
$224,000 for depreciation, $469,000 for salaries and benefits of operating and
editorial personnel and $12,000 for other related operating costs. Increases
were primarily related to additional personnel and equipment required to
maintain a larger number of vertical trade communities.     
 
  Product Development Expenses. Product development expenses were $22,000 for
the Inception Period, $214,000 for the year ended December 31, 1996 and
$711,000 for the year

ended December 31, 1997. From the Inception Period to December 31, 1996,
expenses increased by $68,000 for salaries and benefit costs and $124,000 for
consulting and equipment costs. From the year ended December 31, 1996 to
December 31, 1997, expenses for salaries and benefit costs increased by
$643,000 and consulting and equipment costs decreased by $146,000. This
increase in expenses was primarily due to increased staffing and associated
costs related to enhancing the features, content and services of our vertical
trade communities and increasing the overall number of trade communities.     
   
  Sales and Marketing Expenses. Sales and marketing expenses were $148,000 for
the Inception Period, $268,000 for the year ended December 31, 1996 and $2.3
million for the year ended December 31, 1997. From the Inception Period to the
year ended December 31, 1996, expenses for advertising decreased by $28,000.
Salary, commissions and benefits increased by $98,000 and travel and
entertainment expenses, including costs of attending trade shows, increased by
$50,000. From the year ended December 31, 1996 to December 31, 1997, expenses
increased by $555,000 for advertising, $1.1 million for salary, commissions and
benefits, and $329,000 for travel and entertainment expenses, including costs
of attending trade shows. These increases were primarily due to an increased
sales force and participation in additional trade shows. We expect these
expenses will continue to increase as we expand our direct sales force, hire
additional marketing personnel and increase expenditures for marketing and
promotional activities.     
   
  General and Administrative Expenses.  General and administrative expenses
were $33,000 for the Inception Period, $292,000 for the year ended December 31,
1996 and$1.4 million for the year ended December 31, 1997. From the Inception
Period to December 31, 1996, expenses increased by $78,000 for salaries and
benefit costs, $28,000 for depreciation, $78,000 for professional fees, $45,000
for facility costs and $30,000 for other general and administrative costs. From
the year ended December 31,1996 to December 31, 1997, expenses increased by
$492,000 for salaries and benefit costs, $249,000 for professional fees,
$258,000 for facility costs and $209,000 for other general and administrative
costs. These increases were due primarily to increased staffing levels, higher
facility costs and professional fees to support the growth of our
infrastructure. We expect to hire additional support personnel and will incur
additional costs related to being a public company, including insurance for
directors and officers, investor relations programs and other related
professional fees.     
 
  Interest, Net. Interest income net of expense consists primarily of interest
expense on our line of credit and capital lease obligations. We incurred net
interest expense of $1,000 for the Inception Period, $6,000 for the years ended
December 31, 1996 and $115,000 for the year ended December 31, 1997. Currently,
we invest our cash balances in money market funds.
   
  Income Taxes. As of September 30, 1998, we had approximately $12.4 million of
federal net operating loss carryforwards and $12.7 million of state net
operating loss carryforwards for tax reporting purposes to offset future
taxable income. Our federal net operating loss carryforwards expire beginning
2013 and our state net operating loss carryforwards expire beginning 2000. Due
to the change in our ownership interest in 1997 and 1998, our net operating
loss carryforwards should be subject to certain limitations or annual
restrictions. See Note 12 of Notes to the Financial Statements.

Quarterly Results of Operations
   
  The following table sets forth certain statement of operations data for the
quarters ended March 31, 1997, June 30, 1997, September 30, 1997, December 31,
1997, March 31, 1998, June 30, 1998 and September 30, 1998. The information for
each quarter has been prepared on substantially the same basis as the audited
statements included in other parts of this prospectus and, in the opinion of
management, includes all adjustments, consisting of only normal recurring
adjustments necessary for a fair presentation of the results of operations for
such periods. Historical results are not necessarily indicative of the results
to be expected in the future, and the results of the interim periods are not
indicative of results of any future period.

  Our operating results have varied on a quarterly basis during our short
operating history and may fluctuate significantly in the future. In addition,
the results of any quarter do not indicate results to be expected for a full
fiscal year. Finally, as a result of the foregoing factors, our annual or
quarterly results of operations may be below the expectations of public market
analysts or investors, in which case the market price of the common stock could
be materially adversely affected.
 
Liquidity and Capital Resources
   
  Since our inception, we have primarily financed our operations through the
private placement of our preferred stock, borrowings under a line of credit
with a commercial bank and capital equipment leases. To date, we have raised
approximately $19.2 million from the sale of preferred stock. At September 30,
1998, we had approximately $3.8 million in cash and cash equivalents. We have
had significant negative cash flows from operating activities for each fiscal
and quarterly period to date. Net cash used in operating activities was $48,000
for the Inception Period, $663,000 for the year ended December 31, 1996, $3.8
million for the year ended December 31, 1997; and was $2.3 million for the nine
months ended September 30, 1997 and $6.7 million for the nine months ended
September 30, 1998. Cash used in operating activities from inception through
September 30, 1998 consisted mostly of net operating losses and increases in
accounts receivable and prepaid expenses, partially offset by increases in
deferred revenues, accrued expenses, and accounts payable.     
   
  Net cash used in investing activities was $57,000 for the Inception Period,
$64,000 for the year ended December 31, 1996, $396,000 for the year ended
December 31, 1997; and was $148,000 for the nine months ended September 30,
1997 and $2.8 million for the nine months ended September 30, 1998. Net cash
used in investing activities in these periods consisted mostly of capital
expenditures for purchased software, office equipment and leasehold
improvements. Net cash provided by financing was $136,000 for the Inception
Period, $1.0 million for the year ended December 31, 1996 and $4.6 million for
the year ended December 31, 1997; and was $2.3 million for the nine months
ended September 30, 1997 and $12.5 million for the nine months ended September
30, 1998. Cash provided by financing activities consisted primarily of sales of
our preferred stock and borrowings from Internet Capital Group and Progress
Bank,

which was partially offset by payment on our capital lease obligations. Net
cash used for acquisitions for the nine months ended September 30, 1998 was
approximately $1.9 million.     
   
  We have a line of credit with a commercial bank for $500,000. As of December
31, 1997, we were in technical default on the line of credit for failing to
meet specified financial ratios. The bank waived these covenants for the year
ended December 31, 1997. As of September 30, 1998, there were no borrowings
under the line of credit. The line bears interest at the bank's prime rate of
interest plus 1.5%. Any borrowings under the line of credit will be secured by
most of our assets.     
   
  We have several capital leases with various financial institutions for
equipment with lease terms ranging from three to five years. The interest rates
under the leases range from 8% to 20% and we are required to make monthly
payments of $27,722 under the terms of these leases.     
   
  We believe that the net proceeds from the offering, together with our
existing cash and cash equivalents, will be sufficient to meet our working
capital and capital expenditure requirements for at least the next 12 months.
Thereafter, we may be required to raise additional funds. We may also be
required to raise additional financing before such time. If additional funds
are raised through the issuance of equity securities, our existing shareholders
may experience significant dilution. Furthermore, additional financing may not
be available when needed or, if available, such financing may not be on terms
favorable to us or our shareholders. If such financing is not available when
required or is not available on acceptable terms, we may be unable to develop
or enhance our products or services. In addition, we may be unable to take
advantage of business opportunities or to respond to competitive pressures. Any
of these events could have a material adverse effect on our business, financial
condition or results of operations.     
   
  In November 1998, we issued convertible notes to Internet Capital Group and
certain holders of our Series D Preferred Stock in an aggregate principal
amount of $5.0 million. The convertible notes are required to be repaid in six
months, or upon the closing of the offering, if earlier. At each holder's
option, a holder can convert the principal balance of the convertible note into
our common stock at the initial public offering price. All holders have elected
to convert their notes into our common stock. In connection with the issuance
of the convertible notes, we granted the holders of the notes warrants to
purchase an aggregate of 82,051 shares of our common stock at the initial
public offering price.     
   
  In November 1998, we issued a note to Progress Bank in an aggregate principal
amount of $2.0 million. The note is required to be repaid in six months or upon
the closing of the offering, if earlier. In connection with the issuance of the
note, we granted Progress Capital, an affiliate of Progress Bank, warrants to
purchase 20,513 shares of our common stock at the initial public offering
price. We valued the warrants at the date of grant to Internet Capital Group
and certain holders of our Series D Preferred Stock and Progress Capital and
will amortize the cost over the period we expect the warrants to be
outstanding.     
 
Year 2000 Compliance
   
  We may realize exposure and risk if the systems on which we are dependent to
conduct our operations are not Year 2000 compliant. Our potential areas of
exposure include products purchased from third parties, computers, software,
telephone systems and other equipment used internally. All of the production
and operation systems for our Web

sites are undergoing a complete re-engineering. All new programs are being
tested and validated for Year 2000 compliance. We expect to resolve any Year
2000 compliance issues primarily through normal upgrades of our software or,
when necessary, through replacement of existing software with Year 2000
compliant applications. The cost of these upgrades or replacements is included
in our capital expenditure budget and is not expected to be material to our
financial position or results of operations. We estimate that our total cost
to become Year 2000 compliant will not exceed $250,000. However, such upgrades
and replacements may not be completed on schedule or within estimated costs or
may not successfully address our Year 2000 compliance issues.     
   
  In addition, we are in the process of seeking verification from our key
distributors, vendors and suppliers that they are Year 2000 compliant or, if
they are not presently compliant, to provide a description of their plans to
become so. As of January 15, 1999, we have received certification from 80% of
our distributors, vendors and suppliers that they are either Year 2000
compliant or are taking the necessary steps to become Year 2000 compliant. We
expect to receive the remaining certifications by April 30, 1999.     
   
  In the event that our production and operational facilities that support our
Web sites are not Year 2000 compliant, small portions of our Web sites may
become unavailable. Our review of our systems has shown that there is no
single application that would make our Web sites totally unavailable and we
believe that we can quickly address any difficulties that may arise.     
   
  In the event that our Web-hosting facilities are not Year 2000 compliant,
our Web sites would be unavailable and we would not be able to deliver
services to our users. If our present efforts to address the Year 2000
compliance issues are not successful, or if distributors, suppliers and other
third parties with which we conduct business do not successfully address such
issues, our business, operating results and financial position could be
materially and adversely affected.     
 
Acquisitions
   
  In September 1998, we acquired all of the outstanding capital stock of RF
Globalnet for $1.8 million in cash. Also in September 1998, we acquired all of
the outstanding capital stock of Informatrix for 46,154 shares of our common
stock. Up to 11,538 additional shares of our common stock may be issued to
Informatrix if Informatrix achieves certain performance targets through
December 1998. See "Certain Transactions and Stock Issuances with Executive
Officers, Directors and Our Largest Shareholder." These performance targets
were met for the period ended September 30, 1998 and we will be required to
issue 2,200 additional shares of common stock pursuant to this arrangement.
The performance targets were based on selling advertisements in the period,
not the profitability of the site. The per share value was $3.32 for the
additional shares, based on the value assigned to option grants made to our
employees during the same period. The date of the issuance was October 1998.
Those Informatrix employees who remained after the acquisition are now our
employees.     
   
  We have reported pro forma results of operations as if we had consummated
the acquisition of RF Globalnet on January 1, 1997 and the acquisition of
Informatrix on October 15, 1997 (inception). The pro forma net loss for the
year ended December 31, 1997 was $5.8 million compared to the actual net loss
of $4.8 million. The increase in the net loss results from the net losses of
the acquired companies

and the pro forma amortization of the goodwill associated with the
acquisitions. The pro forma net loss for the nine months ended September 30,
1998 was $9.8 million compared to the actual net loss of $8.3 million. The
increase in the net loss is primarily related to the losses of the companies
acquired and the pro forma amortization of the goodwill associated with the
acquisitions.
   
  On January 13, 1999, we purchased the online business, operated as safety
online, from Coastal Video Communication Corp. for $260,000 in cash and a
$50,000 note which is payable without interest no earlier than 90 days from
such date. We also provided Coastal with an advertising commitment on our Web
site, which will be subsequently valued. This Web site is used by
professionals in the safety industry.     
          
Other Commitments     
   
  Our financial commitments for our marketing and distribution agreements with
Excite and AltaVisa are $2.3 million in 1999, $2.3 million in 2000 and $2.0
million in 2001. These agreements renew automatically unless terminated by
either party upon 30 days notice prior to the anniversary of the agreement.
    
Recent Accounting Pronouncements
   
  In June 1997, Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income," which establishes standards for reporting
and display of comprehensive income and its components in the financial
statements. SFAS No. 130 is effective for fiscal years beginning after
December 15, 1997. Reclassification of financial statements for earlier
periods provided for comparative purposes is required. SFAS No. 130 offers
alternatives for presentation of disclosures required by the standard. The
adoption of SFAS No. 130 will have no impact on our results of operations,
financial position or cash flows.     
   
  In June 1997, FASB issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information," which establishes standards for reporting
information about operating segments in annual financial statements. It also
establishes standards for related disclosures about products and services,
geographic areas and major customers. SFAS No. 131 is effective for fiscal
years beginning after December 15, 1997. The adoption of SFAS No. 131 is not
expected to have an impact on our results of operations, financial position or
cash flows.     
   
  In February 1998, FASB issued SFAS No. 132, "Employers' Disclosures about
Pension and Other Postretirement Benefits," which revises employers'
disclosures about pension and other postretirement benefit plans. SFAS No. 132
does not change the measurement or recognition of those plans. SFAS No. 132 is
effective for fiscal years beginning after December 15, 1997. The adoption of
SFAS No. 132 is not expected to have an impact on our results of operations,
financial position or cash flows.     
   
  In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, "Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use." Statement of Position 98-1 is
effective for financial statements for years beginning after December 15,
1998. Statement of Position 98-1 provides guidance over accounting for
computer software developed or obtained for internal use including the
requirement to capitalize specified costs and amortization of such costs. We
do not expect this standard to have a material effect on our capitalization
policy.

  In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-5, "Reporting on the Costs of Start-Up Activities."
Statement of Position 98-5, which is effective for fiscal years beginning
after December 15, 1998, provides guidance on the financial reporting of
start-up costs and organization costs. It requires costs of start up
activities and organization costs to be expensed as incurred. As we have
expensed these costs historically, the adoption of this standard is not
expected to have a significant impact on our results of operations, financial
position or cash flows.     
 
  In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivatives and
Hedging Activities," which establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts (collectively referred to as derivatives), and for hedging
activities. SFAS No. 133 is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. As we do not currently engage or plan to engage
in derivative or hedging activities, there will be no impact to our results of
operations, financial position or cash flows upon the adoption of this
standard.

                                  OUR BUSINESS
   
  We own and operate 33 industry-specific communities of commerce on the
Internet. These vertical trade communities are business-to-business Web sites
that act as comprehensive sources of information, interaction and electronic
commerce.     
   
  Our communities combine:     
 . product information;
   
 . requests for proposals;     
 . discussion forums;
   
 . electronic commerce opportunities;     
 . industry news;
 . directories;
 . classifieds;
   
 . job listings; and     
   
 . online professional education courses.     
          
  Each vertical trade community is individually branded, focuses on one
business sector and caters to individuals with similar professional interests.
We design each of our vertical trade communities to attract professionals
responsible for selecting and purchasing highly specialized industry related
products and services.     
 
Industry Overview
   
 Growth of the Internet, Online Advertising and Electronic Commerce     
 
  The Internet has emerged as a mass communications and commerce medium
enabling millions of people worldwide to share information, create community
among individuals with similar interests and conduct business electronically.
International Data Corporation projects that the number of Internet users will
grow from 100 million in 1998 to 320 million in 2002. In addition to its
emergence as a mass communications medium, the Internet has features and
functions that are unavailable in traditional media, which enable online
merchants to communicate effectively with customers and advertisers to target
users with specific needs and interests.
   
  As a result, the Internet has emerged as an attractive medium for advertising
and electronic commerce. Jupiter Communications estimates that Internet
advertising will grow from $1.9 billion in 1998 to $7.7 billion in 2002.
Forrester Research projects that business-to-business Internet advertising will
grow from $290 million in 1998 to $2.6 billion in 2002.     
   
  Along with the impressive overall growth of the Internet, business-to-
business usage is also growing rapidly, as businesses are increasingly
leveraging the Internet's ability to reach customers globally, deliver
personalized content and open new distribution channels. Forrester forecasts
that business-to-business electronic commerce will grow from $17.0 billion in
1998 to $327.0 billion in 2002. Of that amount, Forrester forecasts that the
value of goods and services purchased through online business auctions will
increase from $8.7 billion in 1998 to $52.6 billion in 2002.     
   
  Traditionally, companies have employed a variety of well-recognized media in
business-to-business advertising, information delivery and communications to
identify, qualify and facilitate commerce with customers. Veronis, Suhler &
Associates estimates that advertising and specialty media spending on the
business-to-business market was more than $70.0 billion in 1998. Business-to-
business buyers and sellers use several advertising and specialty media,
including trade magazines, trade shows, buyer's guides, direct mail, catalogs
and others. In many industries, particularly in highly specialized,
technically-oriented industries, these media have performed a role in the
distribution channel by enabling buyers and     
 
                                       32

sellers to meet, exchange information and ultimately conduct business with one
another.
 
 Need for Online Vertical Trade Communities
   
  While traditional media have historically served a valuable purpose in
facilitating commerce, information delivery, and communications between buyers
and sellers, they have inherent inefficiencies. We believe that:     
 
 . Trade magazines have limited circulation and are not published in real-time;
 . Trade shows are held infrequently and are expensive for attendees and
  exhibitors;
   
 . Buyer's guides are cumbersome to search and provide limited depth of product
  and vendor content;     
   
 . Direct mail responses often provide limited information about the
  prospective customer; and     
   
 . Trade journal advertising can be cost prohibitive for smaller advertisers.
         
  The Internet provides a new medium to meet the specific needs of businesses
and professionals through vertical trade communities. These communities offer
highly targeted content and services. Electronic commerce is a natural
extension of these communities which cannot be easily replicated through
traditional media.     
 
Our Solution
   
  Our solutions move traditional "off-line" trade services to the Internet.
Our portfolio of vertical trade communities target separate industrial sectors
to provide businesses and professionals with high quality content, community
and commerce that include the following attributes:     
   
 . Comprehensive content, services and features: The editors of our vertical
  trade communities provide valuable information on products, technology,
  industry regulations, news and management. We archive historical content,
  enabling users to research through large databases of information. We also
  operate requests for proposals and related posting and response areas.     
   
 . Active community participation: We provide features and services such as
  "Ask the Expert," discussion forums, chat rooms, bulletin boards and career
  centers, all of which foster active community participation among our users.
  We believe active community participation creates loyalty and affinity among
  our users.     
   
 . Targeted cost-effective medium for business-to-business advertising: The
  narrow focus of our communities and the attractive demographics of our
  audiences permit us to command premium advertising rates. Comparative
  statistics show that advertisers pay more for targeted ads than for general
  ones. We also attract small to mid-sized advertisers due to our cost-
  effective advertising reach and highly targeted user base.     
   
 . High quality sales leads: Our communities generate high quality sales leads
  that are timely and effective and contain detailed buyer information. Robust
  sales leads left by buyers allow sellers to respond more effectively.     
 
 . Connects buyers and sellers globally: Vertical trade communities provide an
  online market place that we believe will allow buyers and sellers worldwide
  to exchange information, source products and execute online transactions.
   
  We believe that targeted content, focused audiences and robust sales leads,
combined with our interactive platform, create a premier market place for
electronic commerce.

Our Strategies
   
  Our objective is to be the leading owner and operator of industry specific
communities of commerce. Key strategies to achieve our objective include:     
   
 Expand User Base and Enhance User Experience with New Features, Services and
Content     
 
  We intend to continue increasing the number of users that visit each
community by:
 
 . introducing additional services and features that appeal to the specific
  needs of professionals using the Internet;
   
 . continuing to direct users to our vertical trade communities through
  marketing relationships with search engine providers;     
 
 . providing professionals the opportunity to buy products online that satisfy
  their product-sourcing needs; and
   
 . creating brand awareness through industry trade shows, conferences,
  advertising campaigns with trade publications and alliances with important
  industry trade associations.     
 
  As our user base grows, we anticipate advertisers and suppliers will find our
vertical trade communities an attractive cost-effective medium for advertising
and sales.
 
 Establish and Expand Multiple Revenue Streams
   
 . Advertising. To date, most of our revenues have been derived from selling
  storefronts to the industry suppliers to our communities. We also have sold,
  and intend to grow our sales of, banner advertisements and newsletter
  sponsorships delivered by e-mail. For the nine months ended September 30,
  1998, we generated approximately 96% of our revenues from the sales of
  storefronts, banner advertisements and sponsorships.     
   
 . Electronic Commerce. We believe that electronic commerce is a natural
  extension of our vertical trade communities. Revenues from electronic
  commerce differ from advertising based revenues because they depend on a
  purchase being completed over the Internet. We expect to generate electronic
  commerce revenues by receiving a transaction fee for products sold in our
  communities. Transaction fees are typically paid by the supplier.     
    
   In addition, we expect to pursue electronic commerce opportunities through
 marketing relationships with retailers and service providers focused on
 product distribution. For example, we currently sell books and software in our
 communities where we receive credit for the sale less amounts owed to the
 distributor. For the nine months ended September 30, 1998, we generated
 approximately 2% of our revenues from electronic commerce. See "Risk Factors--
 We May Not Develop Additional Revenue Sources."     
   
 . Career Services. We sell sponsorships in our career center and charge
  employers to post help wanted advertisements. We believe recruiters and
  employers specializing in each industry are natural advertisers and sponsors
  in this area. For the nine months ended September 30, 1998, we generated less
  than 1% of our revenues from the sale of career services.     
 
 . Education. We have partnered with content providers for various engineering
  courses, and are paid a transaction fee for every student taking the course.
  With the
          
 acquisition of RF Globalnet, we acquired technology that allows professionals
 to complete educational courses over the Internet. We are in the process of
 using this technology on other vertical trade communities and expect to form
 partnerships     
 
                                       34

 with courseware providers for industry professionals. For the nine months
 ended September 30, 1998, we generated approximately 1% of our revenues from
 education.     
 
 Continue to Identify and Rapidly Develop New Vertical Trade Communities
   
  We intend to expand our portfolio by building and launching new vertical
trade communities in industry segments that we believe possess significant
opportunities for advertising and electronic commerce.     
 
  We determine whether or not a potential vertical trade community fits our
strategy by looking for specific industry characteristics including:
 . a substantial number of buyers and suppliers;
 . a high degree of fragmentation on both the supply and demand sides;
 . defined target audiences (e.g. chemical engineers) with similar product and
  informational needs;
 . meaningful growth in trade advertising spending;
 . significant new product introductions;
 . online access;
 . growth in trade show attendance; and
 . international components both on the buyer and supplier side.
       
 Leverage the Benefits of a Portfolio Approach
 
  We believe that operating a portfolio of vertical trade communities permits
us to:
   
 . offer a comprehensive, consistent set of services and features;     
   
 . attract a large business-to-business audience, in aggregate, making our
  individual sites appealing to a broad array of advertisers and electronic
  commerce suppliers; and     
   
 . realize cost savings and operating efficiencies in our technology, marketing,
  infrastructure and management resources.     
   
 Form Marketing and Distribution Alliances for Distribution, Technology, and
New Services     
   
  To extend our vertical trade community brands and increase visits to our Web
sites, we intend to form additional marketing and distribution alliances with
search engine providers and other distribution partners.     
 
 Pursue Strategic Acquisitions
   
  We intend to pursue acquisitions of companies that operate vertical trade
communities which would fit into our portfolio. Companies considered for
acquisition are evaluated based on the criteria outlined above under "Continue
to Identify and Rapidly Develop New Vertical Trade Communities." However, we
may also acquire other companies with complementary communities or technologies
such as electronic commerce solutions or other Web-based technologies.
Presently, we are not contemplating any specific acquisitions.     
 
 Expand Globally
   
  We believe that the anticipated growth of Internet usage internationally
presents significant opportunities to extend the global reach of our
communities. For the nine months ended September 30, 1998, more than 25% of the
visits to our vertical trade communities originated outside the United States.
As is shown by their usage levels, international users represent significant
opportunity to our domestic advertisers, providing both sources of leads and,
eventually, purchasers of their products and services. Our vertical trade
communities also provide foreign advertisers access to our targeted audience in
the United States. We intend to expand globally by pursuing strategic
partnerships.

Planned and Expanded Services     
   
  We plan to offer and expand the following services:     
   
  Electronic Commerce: As part of our long term strategy, we plan to increase
our commerce-related services for our advertisers and users of our vertical
trade communities, specifically:     
 
 .  online stores: through simple-to-use store creation software we plan to
   offer any current or future advertiser an interactive platform to sell
   certain products in easy to manage environments;
   
 .  catalog-platforms: we plan to work with current and future advertisers as
   well as industry-specific distributors to create and populate Internet-based
   catalogs;     
   
 .  classifieds: we plan to launch classified sections in each vertical trade
   community listing individual products and a path to the specific seller; and
          
 .  auctions: we plan to launch online industrial auctions for each vertical
   trade community. We expect that new and used equipment will be listed for
   bid.     
   
  E-mail Service:  We plan to offer free e-mail accounts to users/registrants
in each vertical trade community. We expect that the actual address will be
indicative of the specific vertical trade community (e.g.,
[email protected]). We believe that this service will be provided by a
third-party partner, and will be supported by the sale of advertising on the e-
mail pages.

  Visitor traffic information is provided by our Web server log files. Unique
visits are defined as the number of times individuals accessed our Web sites
during the month. In December 1998, our Web sites attracted approximately
650,000 unique visits.     
   
  For the Inception Period and the years ended 1996 and 1997, water online was
the only vertical trade community that accounted for more than 15% of our
revenues. Water online represented 100% of our revenues for the Inception
Period and the year ended 1996, and 40% of our revenues for the year ended
1997. For the year ended December 31, 1998, water online was the only vertical
trade community to account for more than 15% of our revenues, accounting for
20% of the revenues for such period.     
          
Marketing and Distribution Alliances     
          
  We have recently entered into the following alliances:     
 
 Excite Agreement
   
  We have entered into a three-year renewable sponsorship agreement with
Excite, a leading Internet navigational service provider, to build and operate
an industrial "channel" on the Excite service for each of up to 30 of our
vertical trade communities. These channels are highlighted summaries of much of
the content and features of the home page of each of our vertical trade
communities, and provide a preview of the content and services offered on each
vertical trade community. For an annual fee, Excite will deliver guaranteed
minimum performance levels for exposures (or impressions) in each year. As part
of the Excite agreement, we and Excite have committed to provide advertising on
each others' Web sites.     
 
 Junglee Agreement
   
  We have an agreement with Junglee Corp., a subsidiary of Amazon.com, which
allows our visitors to utilize Junglee's technology in order to easily compare
product price and features from various suppliers and complete transactions
online. As part of the agreement, we share in both advertising revenues and
transaction fees generated from the Junglee Marketplace.     
       
       
       
          
 AltaVista Agreement     
   
  We recently entered into a renewable one year agreement with AltaVista, a
leading search engine company, to develop at least thirty-one co-branded Web
sites. AltaVista has guaranteed us minimum levels of visits to our Web sites in
    
                                       43

exchange for an annual fee. In addition, advertising revenues generated from
the co-branded Web sites will be shared between us and AltaVista.     
   
 Other Relationships--Motorola     
   
  In October 1998, we entered into an agreement with Motorola pursuant to which
we provide intranet-based educational services to engineers at Motorola. The
content in our course portfolio is available via the Internet and/or Motorola's
corporate intranet to authorized students registered by Motorola. The contract
requires Motorola to purchase from us pre-defined minimum education services.
The contract expires on June 30, 1999.     
 
Customers
   
  As of December 31, 1998, approximately 700 companies, who have purchased
approximately 1,300 storefronts, advertised in one or more of our vertical
trade communities.     
   
  As of December 31, 1998, our customers included:     
   Asea Brown Boveri Ltd.
   Bailey-Fisher & Porter

Sales and Marketing
 
 Sales and Distribution
 
  We use a variety of programs to stimulate demand for our products, including
telesales, a direct sales force and reseller arrangements with advertising
agencies.
   
  Direct Sales. Our direct sales force targets organizations that sell the
products and services that are utilized and purchased by the professionals that
visit our vertical trade communities. As of December 31, 1998, we had 44 direct
sales and support personnel. We often employ individuals with a background in
advertising sales with trade publishing companies.     
   
  Telesales. We currently maintain an in-house telesales group for use in
customer prospecting, lead generation and lead follow-up. As of December 31,
1998, we had 15 people in our telesales group and we are expanding the products
sold by the group, such as job listings and banner advertisements.     
   
  International. We intend to market our products and services to international
markets directly over the Internet, as well as through resellers and affiliate
relationships. Currently, we derive less than 3% of revenues from international
customers. For the nine months ended September 30, 1998, more than 25% of the
visits to our vertical trade communities originated outside the United States.
We believe that the large percentage of international users are attractive to
advertisers who want to reach customers globally. See""--Our Strategies--
Establish and Expand Multiple Revenue Streams."     
 
 Marketing
   
  We use a variety of marketing programs to increase brand awareness. Our
marketing goals are to create and enhance the awareness of each branded
vertical trade community as a destination for professionals in each industry
sector and to promote the VerticalNet brand with suppliers, media buyers, and
interactive services companies. Our marketing strategy for each contains a mix
of print advertising, outbound e-mail, telemarketing, new media banner
campaigns, trade shows and direct mail. We also participate in industry
specific events, industry association activities and partnerships with
interactive services companies. We believe that forming strategic marketing and
distribution alliances with partners in the Internet, print publishing and
industry associations will be important for rapid market penetration.     
 
Technology
   
  We have developed and implemented a broad array of technologies including
site management, search, customer interaction and transaction processing
systems using a combination of our own proprietary technologies and
commercially available, licensed technologies. For example, we recently
developed an application available on our Web sites which allows our clients to
track the success of their advertising campaigns. We also developed an
application using the Microsoft Site Server Suite of development tools which
allows clients to sell products over the Internet. Our current strategy is to
license commercially available technology whenever possible rather than seek
internally developed systems.     
   
  Scalability. The scalable structure of our hardware and software is designed
to allow for rapid deployment of multiple vertical trade communities while
maintaining desired user performance standards. In the rapidly changing
Internet environment, the ability to update an application to stay current with
new technologies is important. The system's template technology and generic
database design allow for the addition, modification, or replacement of Web
site based applications in a cost-efficient and expeditious manner.

  Reliability and Security. We use CheckPoint's Firewall-1 software to protect
our Web servers. We also use Netscape software as our Web server. Our
production machines are located at Exodus Communications Inc. and at Icon CMT
Corp., which provide professional data center hosting facilities and redundant
high-speed Internet connectivity. Exodus and Icon provide monitoring and
support 24 hours a day, seven days a week supplementing our system
administrators.     
          
  We have developed our own content and Web site management tools to facilitate
the maintenance and updating of our vertical trade communities. Our Web site
management tools allow our editors to update our Web sites from remote
locations throughout the day.     
 
Proprietary Rights
 
  Proprietary rights are important to our success and our competitive position.
To protect our proprietary rights, we rely generally on copyright, trademark,
and trade secret laws, confidentiality agreements with employees and third
parties, and license agreements with consultants, vendors, and customers.
Despite such protections, a third party could, without authorization, copy or
otherwise appropriate information from our vertical trade community sites. Our
agreements with employees, consultants and others who participate in
development activities could be breached, we may not have adequate remedies for
any breach, and our trade secrets may otherwise become known or independently
developed by competitors.
 
  We rely upon license agreements for the majority of our content and
technology. Such license agreements may not continue to be available to us on
acceptable terms, or at all. We do not, however, believe that we are dependent
upon any single licensor of technology or content.
   
  We have applied for numerous trademarks, none of which have been issued to
date. We currently have two pending applications for trademarks. Generally, we
cannot protect our Web addresses for our vertical trade communities as
trademarks due to the fact that they are too generic. The laws of some foreign
countries do not protect our proprietary rights to the same extent as do the
laws of the United States, and effective copyright, trademark and trade secret
protection may not be available in such jurisdictions.     
   
  There have been substantial amounts of litigation in the computer industry
regarding intellectual property assets. Third parties may claim infringement by
us with respect to current and future products, trademarks or other proprietary
rights, or we may counterclaim against such parties in such actions. Any such
claims or counterclaims could be time-consuming, result in costly litigation,
diversion of management's attention, cause product release delays, require us
to redesign our products or require us to enter into royalty or licensing
agreements, any of which could have a material adverse effect upon our
business, financial condition and operating results. Such royalty and licensing
agreements, if required, may not be available in terms acceptable to us, or at
all.     
   
Government Regulations and Legal Uncertainties     
   
  We are subject to various laws and regulations relating to our business. Few
laws or regulations are currently directly applicable to access to the
Internet. However, because of the Internet's popularity and increasing use, new
laws and regulations may be adopted. Such laws and regulations may cover issues
such as:     
   
 . user privacy;     
   
 . pricing;     
 
 
                                       46

 . content;     
   
 . copyrights;     
   
 . distribution; and     
   
 . characteristics and quality of products and services.     
   
  In addition, the growth of the Internet and electronic commerce, coupled with
publicity regarding Internet fraud, may lead to the enactment of more stringent
consumer protection laws. These laws may impose additional burdens on our
business. The enactment of any additional laws or regulations may impede the
growth of the Internet, which could decrease our potential revenues from
electronic commerce or otherwise adversely affect our business, financial
condition and operating results.     
   
  Laws and regulations directly applicable to electronic commerce or Internet
communications are becoming more prevalent. The most recent session of Congress
enacted Internet laws regarding on-line copyright infringement. Although not
yet enacted, Congress is considering laws regarding Internet taxation. The
European Union recently enacted new privacy regulations. These are all recent
enactments, and there is uncertainty regarding their marketplace impact. In
addition, various jurisdictions already have enacted laws that are not
specifically directed to electronic commerce but that could affect our
business. The applicability of many of these laws to the Internet is uncertain
and could expose us to substantial liability. Any new legislation or regulation
regarding the Internet, or the application of existing laws and regulations to
the Internet, could materially adversely affect us. If we were alleged to
violate federal, state or foreign, civil or criminal law, even if we could
successfully defend such claims, it could materially adversely affect us.     
   
  We believe that our use of third party material on our vertical trade
communities is permitted under current provisions of copyright law. However,
because legal rights to certain aspects of Internet content and commerce are
not clearly settled, our ability to rely upon exemptions or defenses under
copyright law is uncertain.     
   
  Several telecommunications carriers are seeking to have telecommunications
over the Internet regulated by the Federal Communications Commission in the
same manner as other telecommunications services. Additionally, local telephone
carriers have petitioned the Federal Communications Commission to regulate
Internet service providers and online service providers in a manner similar to
long distance telephone carriers and to impose access fees on such providers.
If either of these petitions are granted, the costs of communicating on the
Internet could increase substantially. This, in turn, could slow the growth of
use of the Internet. Any such legislation or regulation could materially
adversely affect our business, financial condition and operating results.     
 
Competition
   
  The market for vertical trade communities is new and rapidly evolving.
Competition for advertising, electronic commerce and business users is intense
and is expected to increase significantly in the future. Technological barriers
to entry are relatively insubstantial. We believe that the principal
competitive factors for companies seeking to create vertical trade communities
on the Internet are targeted advertising, services and features, real-time
information access, quality sales leads, detailed user information, global
reach and business user affinity and loyalty. Several companies are primarily
focused on operating business-to-business trade communities on the Internet,
but

most existing online competition is ancillary to the traditional business of
trade publishers, industry and trade associations and directory companies. We
will likely face intensified competition in the future from traditional trade
publishers, such as McGraw Hill and Reed Elsevier, directory registry
companies, such as Thomas Register, as well as from Internet search engine
companies, trade associations and electronic commerce technology suppliers.
Further, our potential competitors may develop vertical trade communities that
are equal or superior to ours. We also compete with traditional forms of
business-to-business advertising and commerce, such as trade magazines, trade
shows, and trade associations for advertisers and advertising revenue. We
believe that the principal competitive factors in attracting advertisers
include the demographics of our users, our ability to offer targeted audiences
and the overall cost-effectiveness of the advertising medium offered by us. We
believe that the number of business-to-business Internet companies relying on
Internet-based advertising revenue will increase greatly in the future, which
would increase pricing pressure on our advertising rates.     
 
Employees
   
  As of December 31, 1998, we had 187 full-time employees. We consider our
relationships with our employees to be good. None of our employees are covered
by collective bargaining agreements.     
 
Properties
   
  Our corporate headquarters are located at 2 Walnut Grove Drive in an office
facility in Horsham, Pennsylvania, where we lease approximately 13,343 square
feet under a lease that expires February 1, 2001. We also maintain a sales and
editorial office in Parsippany, New Jersey, under a lease that expires July 15,
1999. We also lease a small corporate facility in Washington, D.C. under a
lease that expires April 14, 2000 and a sales and editorial office in
Deerfield, Illinois under a lease that expires July 31, 2001. We also lease a
corporate office for RF Globalnet in Boulder, Colorado, under a lease that
expires February 28, 1999.     
   
  We maintain most of our computer systems in two Web-hosting facilities in New
Jersey. For our Web-hosting facilities, we entered into a one year services
agreement with Exodus on July 31, 1998 and an agreement with Icon CMT Corp on
July 1, 1997. The Exodus agreement automatically renews for additional one year
terms unless terminated by prior written notice. We expect that we will allow
the Icon agreement to expire this year by its terms.

Stock Option Plan
 
  We have adopted the Amended and Restated 1996 Equity Compensation Plan,
effective as of December 18, 1996. The plan provides for grants of incentive
stock options, nonqualified stock options, and restricted stock to our
designated employees, advisors and consultants, and to non-employee directors.
By encouraging stock ownership, we seek to motivate such individuals to
contribute materially to our success.
   
  General. The plan authorizes up to 3,600,000 shares of common stock for
issuance under the terms of the plan. No more than 500,000 shares in the
aggregate may be granted to any individual in any calendar year. If options
granted under the plan expire or are terminated for any reason without being
exercised, or shares of restricted stock are forfeited, the shares of common
stock underlying such grant will again be available for purposes of the plan.
       
  Administration of the Plan. The compensation committee of the board of
directors administers and interprets the plan. The compensation committee will
consist of two or more persons appointed by the board of directors from among
its members, each of whom must be a "non-employee director" as defined by Rule
16b-3 under the Securities Exchange Act of 1934, and an "outside director" as
defined by Section 162(m) of the Internal Revenue Code of 1986 and related
Treasury regulations. The compensation committee has the sole authority to:
       
 .  determine the individuals to whom grants shall be made under the plan;
           
 .  determine the type, size and terms of the grants to be made to each such
    individual;     
    
 .  determine the time when the grants will be made and the duration of any
    applicable exercise or restriction period, including the criteria for
    vesting and the acceleration of vesting;     
    
 .  determine the total number of shares of common stock available for grants;
    and     
    
 .  deal with any other matters arising under the plan.     
   
  The compensation committee may require that a grantee execute a
shareholder's agreement, with such terms as the compensation committee deems
appropriate.     
   
  Grants. Grants under the plan may consist of:     
    
 .  options intended to qualify as incentive stock options within the meaning
    of Section 422 of the Internal Revenue Code;     
    
 .  nonqualified stock options that are not intended to so qualify; and     
    
 .  restricted stock.     
   
  Eligibility for Participation. Grants may be made to any employees of
VerticalNet or any of its subsidiaries and to any non-employee member of the
board of directors. Key consultants and advisors who perform services for us
or any of our subsidiaries are eligible if they render bona fide services, not
as part of the offer or sale of securities in a capital-raising transaction.
As of December 31, 1998, 2,083,861 options were outstanding under the plan.
       
  Options. Incentive stock options may be granted only to employees. Non-
qualified stock options may be granted to employees, non-employee directors,
and key advisors. The exercise price of common stock underlying an option
shall be determined by the compensation committee, and may be equal to,
greater than, or less than the fair market value but in no event less than 80%
of fair market value; provided that     
    
 (a)  the exercise price of an incentive stock option shall be equal to or
      greater than     
 
                                      55
 
                                                                     Management
<PAGE>
 
       
    the fair market value of a share of common stock on the date such
    incentive stock option is granted and     
    
 (b)  the exercise price of an incentive stock option granted to an employee
      who owns more than 10% of the common stock may not be less than 110% of
      the fair market value of the underlying shares of common stock on the
      date of grant.     
 
The participant may pay the exercise price:
 
 (1) in cash;
    
 (2) with the approval of the compensation committee, by delivering shares of
     common stock owned by the grantee and having a fair market value on the
     date of exercise equal to the exercise price of the grant; or     
    
 (3) by such other method as the compensation committee shall approve,
     including payment through a broker in accordance with procedures
     permitted by Regulation T of the Federal Reserve Board.     
   
  Options vest according to the terms and conditions determined by the
compensation committee and specified in the grant instrument.     
   
  The compensation committee will determine the term of each option up to a
maximum of ten years from the date of grant except that the term of an
incentive stock option granted to an employee who owns more than 10% of the
common stock may not exceed five years from the date of grant. The compensation
committee may accelerate the exercisability of any or all outstanding options
at any time for any reason.     
   
  Restricted Stock. The compensation committee shall determine the number of
shares of restricted stock granted to a participant, but may not exceed the
maximum plan limit described above. Grants of restricted stock will be
conditioned on such performance requirements, vesting provisions, transfer
restrictions or other restrictions and conditions as the compensation committee
may determine in its sole discretion. The restrictions shall remain in force
during a restricted period set by the compensation committee. If the grantee is
no longer employed by us during the restriction period or if any other
conditions are not met, the restricted stock grant will terminate as to all
shares covered by the grant for which the restrictions are still applicable,
and those shares must be immediately returned to us.     
   
  Amendment and Termination of the Plan. The compensation committee may amend
or terminate the plan at any time; except, that, it may not make any amendment
that requires stockholder approval pursuant to Rule 16b-3 of the Securities
Exchange Act of 1934 or Section 162(m) of the Internal Revenue Code without
stockholder approval. The plan will terminate on the day immediately preceding
the tenth anniversary of its effective date, unless the compensation committee
terminated earlier or extends it with approval of the stockholders.     
   
  Adjustment Provisions. Upon certain transactions identified in the plan, the
compensation committee may appropriately adjust:     
    
 .  the maximum number of shares available for grants;     
    
 .  the maximum number of shares that any participant may be granted in any
    year;     
    
 .  the number of shares covered by outstanding grants;     
    
 .  the kind of shares issued under the plan; and     
    
 .  the price per share or the applicable market value of such grants.     
   
  Change of Control. Upon a change of control, the compensation committee may
determine that:     
 
                                       56
 
Management
<PAGE>
 
    
 (1) all outstanding options shall immediately vest; and     
 
 (2) the restrictions and conditions on all outstanding restricted stock shall
     immediately lapse.
   
  Upon a change of control where we are not the surviving entity or where we
survive only as a subsidiary of another entity, unless the compensation
committee determines otherwise, all outstanding grants shall be assumed by or
replaced with comparable options or stock by the surviving corporation. In
addition, the compensation committee may     
 
   (a) require that grantees surrender their outstanding options in exchange
       for payment by us, in cash or common stock, at an amount equal to the
       amount by which the then fair market value of the shares of common
       stock subject to the grantee's unexercised options exceeds the
       exercise price of those options, and/or
 
   (b) after giving grantees an opportunity to exercise their outstanding
       options, terminate any or all unexercised options.
   
  A "change of control" is defined to have occurred if:     
    
 (1) any "person" other than persons who are our shareholders as of the
     effective date of the plan becomes a "beneficial owner," directly or
     indirectly, of common stock representing more than 50% of the voting
     power of the then-outstanding shares of common stock; the terms "person"
     and "beneficial owner" are each defined in the Securities Exchange Act of
     1934; or     
 
 (2) the shareholders or the directors, as appropriate, approve:
      
   (a) any merger or consolidation of us with another corporation where the
       shareholders, immediately prior to such transaction, will not
       beneficially own, immediately after the transaction, shares entitling
       such shareholders to more than 50% of all votes to which all
       shareholders of the surviving corporation would be entitled in the
       election of directors, without consideration of the rights of any
       class of stock to elect directors by a separate class vote;     
 
   (b) the sale or other disposition of all or substantially all our assets;
       or
 
   (c) our liquidation or dissolution.
   
  Section 162(m). Under Section 162(m) of the Internal Revenue Code, we may be
precluded from claiming a federal income tax deduction for total remuneration
in excess of $1.0 million paid to the chief executive officer or to any of the
other four most highly compensated officers in any one year. Total
remuneration would include amounts received upon the exercise of stock options
granted under the plan and the value of shares received when the shares of
restricted stock became transferable or such other time when income is
recognized. An exception does exist, however, for "performance-based
compensation," including amounts received upon the exercise of stock options
pursuant to a plan approved by stockholders that meets certain requirements.
The plan has been approved by stockholders and is intended to make grants of
options thereunder meet the requirements of "performance-based compensation."
Awards of restricted stock generally will not qualify as "performance-based
compensation."     
 
Employment Agreements
   
  Under an employment letter dated August 1997, Mark L. Walsh agreed to be our
President and Chief Executive Officer.     
 
                                      57
 
                                                                     Management
<PAGE>
 
   
Under this employment letter, Mr. Walsh receives a base salary of $200,000 per
year, and a bonus of up to $100,000 per year based on our attainment of certain
performance objectives established at the discretion of the compensation
committee. In connection with the employment letter, we granted Mr. Walsh stock
options to purchase 735,703 shares of common stock. Under the employment
letter, if Mr. Walsh is terminated for any reason other than for cause, he is
entitled to a severance payment equal to one year of his base salary. Internet
Capital Group has guaranteed up to $500,000 of any such severance payment.     
   
  Under an employment letter dated July 1998, agreed to be a Senior Vice
President. Under the employment letter, Mr. Wynkoop is entitled to receive an
annual salary of $175,000, and a bonus of up to $100,000, 30% of which is
attributable to us meeting certain overall revenue and margin objectives and
70% of which is attributable to our attainment of certain annual sales targets.
Under the employment letter we granted Mr. Wynkoop stock options to purchase
123,077 shares of common stock. The employment letter provides that if Mr.
Wynkoop is terminated for any reason other than for cause, he is entitled to a
severance payment equal to six months of his base salary.     
   
  We may enter into new employment agreements with our executive officers, but
no terms have been established. In addition, we are in the process of
developing a bonus program that would be based on company performance targets
and individual performance targets focusing on profitability and customer
satisfaction goals.     
   
Employee Stock Purchase Plan     
   
  Concurrently with the offering, we intend to establish an employee stock
purchase plan under which a total of 300,000 shares of common stock will be
made available for sale to our employees. We intend the purchase plan to
qualify as an employee stock purchase plan within the meaning of Section 423 of
the Internal Revenue Code of 1986. The board of directors, or by a committee
appointed by the board will administer the purchase plan. Employees are
eligible to participate if they are employed by us or a designated subsidiary
for at least 20 hours per week and for more than five months in any calender
year. The purchase plan permits eligible employees to purchase common stock
through payroll deductions, which, subject to certain limitations, may not
exceed 15% of an employee's compensation.     
   
  The purchase plan will be implemented in a series of consecutive offering
periods, each approximately six months long. Offering periods will begin on the
first trading day after March 31, 1999 and September 30, 1999 of every year and
end on the last trading day in the period six months later. However, the first
offering period will be the period of approximately eight months beginning on
the date the registration statement relating to this prospectus is declared
effective by the Securities and Exchange Commission and ending on the last
trading day in the period ending September 30, 1999. Each participant will be
granted an option to purchase stock on the first day of the six-month purchase
period and such option will be automatically exercised on the last date of each
offering period. The purchase price of each share of common stock under the
purchase plan will be equal to 85% of the lesser of the fair market value per
share of common stock on the start date of that offering period or on the date
of purchase. Employees may modify or end their participation in the offering at
any time during the offering period. Participation ends automatically upon
termination of employment. The purchase plan will terminate in 2009 unless the
board of directors terminates it sooner.

CERTAIN TRANSACTIONS AND STOCK ISSUANCES WITH EXECUTIVE OFFICERS, DIRECTORS AND
                            OUR LARGEST SHAREHOLDER
   
  Both Michael J. Hagan and Michael P. McNulty, executive officers of
VerticalNet, were involved in our founding and organization and may be
considered as our promoters. At our inception in July 1995, we issued 685,479
shares of common stock to Mr. Hagan and 685,479 shares of common stock to Mr.
McNulty. Mr. Hagan and Mr. McNulty each contributed a nominal amount of capital
for our initial capitalization. In January 1998, each of Mr. Hagan and Mr.
McNulty received an incentive stock option grant under the equity compensation
plan to purchase 76,923 shares of common stock.     
   
  In 1996, we borrowed an aggregate principal amount of $100,000 evidenced by
four unsecured term notes from four individuals. Along with the notes, we
issued 672,038 shares of common stock to these individuals. One of these
individuals was a member of our board of directors, Walter Buckley, who also
serves as an officer and director of Internet Capital Group, our largest
shareholder. The notes bore interest at a rate of 7%. The notes were to mature
on February 2001, however, all of the notes were repaid in full, including
interest of $15,771, in May 1998.     
   
  During 1996 and 1997, Internet Capital Group made loans to us, pursuant to a
total of 15 demand notes, in an aggregate principal amount of $3.2 million. We
have subsequently repaid $1.0 million of these loans and interest of $28,803
and exchanged $2.2 million of these loans for 2,222,223 shares of our Series D
Preferred Stock and approximately $1.8 million in cash.     
   
  In 1997, Internet Capital Group guaranteed repayment of up to $2.0 million of
a line of credit with our bank under the line of credit agreement. We repaid
all amounts outstanding under this facility in May 1998 and consequently, our
bank released the guarantee from Internet Capital Group.     
   
  In 1997, in conjunction with our entering into an employment letter agreement
with Mark L. Walsh, Internet Capital Group guaranteed the payment of
approximately $500,000 in potential severance payments in the event his
employment is terminated for any reason other than cause. See "Management--
Employment Agreements."     
   
  During 1997, we entered into a $250,000 Web site development contract with
Informatrix. In addition, under the contract we were to maintain the Web site
for a monthly fee of $20,000. In conjunction with this contract, we advanced
Informatrix $160,000 in 1997, as evidenced by a demand note. During the nine
months ended September 30, 1998, we advanced an additional $555,000 to
Informatrix as part of the demand note. Mr. McNulty's brother was a member of
the board of directors of Informatrix. Subsequently, in September 1998, we
acquired all of the outstanding capital stock of Informatrix.     
   
  In May 1998, we issued warrants to Internet Capital Group that will, in the
aggregate, entitle Internet Capital Group to purchase 85,470 shares of common
stock at $3.51 per share. We issued the warrants in conjunction with certain
guarantees of our bank debt by Internet Capital Group. Such warrants are
currently exercisable, and will expire on November 30, 2008. The exercise price
and number of shares of common stock issuable upon the exercise of each of the
warrants may be adjusted upon the occurrence of certain events, including stock
splits, stock dividends, reorganization, recapitalization, merger or sale

of all or substantially all of our assets. All shares of common stock issuable
upon exercise of all warrants have certain registration rights. See
"Description of Capital Stock--Registration Rights."     
          
  Since inception, we have issued, in private placement transactions, shares of
preferred stock that will automatically convert into an aggregate of 9,734,846
shares of common stock upon or immediately before the closing of the offering.
To date, we do not owe and have never paid dividends on our preferred stock.
The holders of such converted shares of common stock are entitled to certain
demand and piggy-back registration rights. See "Description of Capital Stock--
Registration Rights."     
   
  The following table sets forth information about our preferred stock that was
outstanding before the offering. All these shares of preferred stock convert
into common stock upon the closing of the offering.

  Prior to the offering, Internet Capital Group owns all of the shares of
Series A Preferred Stock, all of the shares of Series B Preferred Stock and
1,139,602 shares of Series D Preferred Stock. The purchase price for the shares
of Series A, Series B and Series D Preferred Stock was paid by Internet Capital
Group in cash and/or by the exchange of the principal amount plus accrued
interest of notes. Douglas A. Alexander, our Chairman of the Board, is a
Managing Director of Internet Capital Group. Walter W. Buckley, III, one of our
directors, is the President and CEO of Internet Capital Group. He joined our
board of directors in September 1996 after the completion of the issuance of
the Series A Preferred Stock. After the offering, Internet Capital Group's
right to elect directors terminates when their preferred stock converts to
common stock.     
   
  In November 1998 we issued a $4.1 million convertible note to Internet
Capital Group. In conjunction with the issuance of the convertible note, we
issued warrants to purchase 68,370 shares of common stock at the initial public

<PAGE>
 
                          DESCRIPTION OF CAPITAL STOCK
   
  Our authorized capital stock consists of 90,000,000 shares of common stock,
par value $.01 per share, and 10,000,000 shares of preferred stock, par value
$.01 per share.     
 
Common Stock
 
  Holders of the common stock are entitled to receive, as, when and if declared
by the board of directors from time to time, such dividends and other
distributions in cash, stock or property from our assets or funds legally
available for such purposes subject to any dividend preferences that may be
attributable to preferred stock that may be authorized. Holders of common stock
are entitled to one vote for each share held of record on all matters on which
shareholders may vote, except with respect to the election of directors in
which case shareholders are entitled to multiply the number of shares held of
record by the number of directors to be elected and distribute such number of
votes for one or among two or more nominees.
 
  There are no preemptive, conversion, redemption or sinking fund provisions
applicable to the common stock. All outstanding shares of common stock are
fully paid and non-assessable. In the event of our liquidation, dissolution or
winding up, holders of common stock are entitled to share ratably in the assets
available for distribution.
 
Preferred Stock
   
  Our board of directors, without further action by the shareholders, is
authorized to issue an aggregate of 10,000,000 shares of preferred stock. No
shares of preferred stock are outstanding and we have no plans to issue a new
series of preferred stock. Our board of directors may, without shareholder
approval, issue preferred stock with dividend rates, redemption prices,
preferences on liquidation or dissolution, conversion rights, voting rights and
any other preferences, which rights and preferences could adversely affect the
voting power of the holders of common stock. Issuance of preferred stock, while
providing desirable flexibility in connection with possible acquisitions or
other corporate purposes, could have the effect of making it more difficult for
a third party to acquire, or could discourage or delay a third party from
acquiring, a majority of our outstanding stock. See "Certain Transactions and
Stock Issuances with Executive Officers, Directors and Our Largest
Shareholder."     
 
Common Stock Warrants
   
  We have warrants outstanding for the purchase of 235,871 shares of our common
stock with a weighted average exercise price of $5.37 per share.     
   
  Warrants issued to Progress Capital on April 30, 1997 will entitle Progress
Capital to purchase 19,347 shares of common stock for $0.76 per share. Warrants
issued to Internet Capital Group on May 12, 1998 will, in the aggregate,
entitle Internet Capital Group to purchase 85,470 shares of common stock at
$3.51 per share. Warrants issued to Progress Capital on May 12, 1998 will
entitle Progress Capital to purchase 28,490 shares of common stock for $3.51
per share. Such warrants are currently exercisable, and expire on November 30,
2008.     
          
  Additional warrants to purchase an aggregate of 82,051 shares of common stock
at the initial public offering price per share were issued to Internet Capital
Group and certain holders of our Series D Preferred Stock in November, 1998.
       
  Additional warrants to purchase 20,513 shares of common stock at the initial
public offering price per share were issued to Progress Capital in November,
1998.

Description of Capital Stock
<PAGE>
 
   
  The exercise price and number of shares of common stock issuable upon the
exercise of each of the warrants may be adjusted upon the occurrence of
certain events, including stock splits, stock dividends, reorganization,
recapitalization, merger, or sale of all or substantially all of our assets.
All warrants and shares of stock issuable upon exercise of all warrants have
certain registration rights as described under "Registration Rights" below.
    
Classified Board of Directors
   
  Our bylaws, as amended and restated, divide our board of directors into
three classes, with regular three-year staggered terms and initial terms of
three years for the class I directors, two years for the class II directors
and one year for the class III directors. Our bylaws also provide for
cumulative voting. This allows holders of common stock in electing directors
to multiply the number of shares they are entitled to vote by the number of
directors to be elected and allocate such votes for one or among two or more
nominees. Accordingly, a minority stockholder holding a sufficient number of
shares may be able to ensure the election of one or more directors of each
class. This, combined with the classified board, could prevent a party who
acquires control of the majority of the outstanding voting stock from
obtaining control of the board of directors.     
 
Shareholder Action by Written Consent
 
  Our bylaws provide that any action that may be taken at a meeting of the
shareholders may be taken without a meeting if:
 
 (1) such action is authorized by the unanimous written consent of all
     shareholders entitled to vote at a meeting for such purposes; or
 
 (2) such action is authorized by written consent of such number of
     shareholders required by law who are entitled to vote thereon at a
     meeting of the shareholders or of a class of shareholders.
 
Special Meetings
 
  Our bylaws provide that special meetings of our shareholders may be called
only by the board or by our president. This provision may make it more
difficult for shareholders to take action opposed by the board.
 
Amendments to Our Bylaws
 
  Our bylaws provide that the vote of a majority of all directors or the vote
of the majority of the outstanding stock entitled to vote is required to
alter, amend or repeal our bylaws.
 
Indemnification of Directors and Officers
   
  Section 1741 of the Pennsylvania corporate laws provides the power to
indemnify any officer or director acting in his capacity as our representative
who was, is or is threatened to be made a party to any action or proceeding
for expenses, judgments, penalties, fines and amounts paid in settlement in
connection with such action or proceeding. The indemnity provisions apply
whether the action was instituted by a third party or arose by or in our
right. Generally, the only limitation on our ability to indemnify our officers
and directors is if the act violates a criminal statute or if the act or
failure to act is finally determined by a court to have constituted willful
misconduct or recklessness.     
   
  Our bylaws provide a right to indemnification to the full extent permitted
by law for expenses, attorney's fees, damages, punitive damages, judgments,
penalties, fines and amounts paid in settlement actually and reasonably
incurred by any director or officer whether or not the indemnified liability
arises or arose from any threatened, pending or     
 
                                      63
 
                                                   Description of Capital Stock

completed proceeding by or in our right by reason of the fact that such
director or officer is or was serving as our director, officer or employee or,
at our request, as a director, officer, partner, fiduciary or trustee of
another corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise, unless the act or failure to act giving rise to the claim
for indemnification is finally determined by a court to have constituted
willful misconduct or recklessness. Our bylaws provide for the advancement of
expenses to an indemnified party upon receipt of an undertaking by the party to
repay those amounts if it is finally determined that the indemnified party is
not entitled to indemnification.     
 
  Our bylaws authorize us to take steps to ensure that all persons entitled to
the indemnification are properly indemnified, including, if the board of
directors so determines, purchasing and maintaining insurance.
 
Limitation of Liability
 
  Our articles of incorporation provide that none of our directors shall be
personally liable to us or our shareholders for monetary damages for a breach
of fiduciary duty as a director, except for liability:
    
 .  for any breach of such person's duty of loyalty;     
    
 .  for acts or omissions not in good faith or involving intentional
    misconduct or a knowing violation of law;     
    
 .  for the payment of unlawful dividends and certain other actions prohibited
    by Pennsylvania corporate law; and     
    
 .  for any transaction resulting in receipt by such person of an improper
    personal benefit.     
 
  We maintain directors and officers' liability insurance to provide directors
and officers with insurance coverage for losses arising from claims based on
breaches of duty, negligence, error and other wrongful acts. At present, there
is no pending litigation or proceeding, and we are not aware of any threatened
litigation or proceeding, involving any director, officer, employee or agent
where indemnification will be required or permitted under the articles of
incorporation or our bylaws.
 
Pennsylvania Control-Share Acquisitions Law
   
  Generally, subchapters 25E, F, G, H, I and J of the Pennsylvania corporate
laws place certain procedural requirements and establish certain restrictions
upon the acquisition of voting shares of a corporation which would entitle the
acquiring person to cast or direct the casting of a certain percentage of votes
in an election of directors. Subchapter 25E of the Pennsylvania corporate laws
provides generally that, if a company were involved in a "control transaction,"
shareholders of the company would have the right to demand from a "controlling
person or group" payment of the fair value of their shares. For purposes of
subchapter 25E, a "controlling person or group" is a person or group of persons
acting in concert that, through voting shares, has voting power over at least
20% of the votes which shareholders of the company would be entitled to cast in
the election of directors. A control transaction arises, in general, when a
person or group acquires the status of a controlling person or group.     
   
  In general, Subchapter 25F of the Pennsylvania corporate laws delays for five
years and imposes conditions upon "business combinations" between an
"interested shareholder" and us. The term "business combination" is defined
broadly to include various merger, consolidation, division, exchange or sale
transactions, including     
 
                                       64
 
Description of Capital Stock
<PAGE>
 
transactions utilizing our assets for purchase price amortization or
refinancing purposes. An "interested shareholder," in general, would be a
beneficial owner of at least 20% of our voting shares.
   
  In general, Subchapter 25G of the Pennsylvania corporate laws suspends the
voting rights of the "control shares" of a shareholder that acquires for the
first time 20% or more, 33 1/3% or more, or 50% or more of a company's shares
entitled to be voted in an election of directors. The voting rights of the
control shares generally remain suspended until such time as the
"disinterested" shareholders of the company vote to restore the voting power
of the acquiring shareholder.     
   
  Subchapter 25H of the Pennsylvania corporate laws provides in certain
circumstances for the recovery by a company of profits made upon the sale of
its common stock by a "controlling person or group" if the sale occurs within
18 months after the controlling person or group became such and the common
stock was acquired during such 18 month period or within 24 months before such
period. In general, for purposes of Subchapter 25H, a "controlling person or
group" is a person or group that:     
 
 (1) has acquired;
 
 (2) offered to acquire; or
 
 (3) publicly disclosed or caused to be disclosed an intention to acquire
     voting power over shares that would entitle such person or group to cast
     at least 20% of the votes that shareholders of the company would be
     entitled to cast in the election of directors.
   
  If the disinterested shareholders of a company vote to restore the voting
power of a shareholder who acquires control shares subject to Subchapter 25G,
such company would then be subject to subchapters 25I and J of the
Pennsylvania corporate laws. Subchapter 25I generally provides for a minimum
severance payment to certain employees terminated within two years of such
approval. Subchapter 25J, in general, prohibits the abrogation of certain
labor contracts prior to their stated date of expiration.     
   
  The above descriptions of certain subchapters of the Pennsylvania corporate
laws summarize the material anti-takeover provisions contained in the
Pennsylvania corporate laws but are not a complete discussion of those
provisions.     
 
Certain Anti-Takeover Provisions
   
  The ability of the board of directors to establish the rights of, and to
issue, substantial amounts of Preferred Stock without the need for shareholder
approval, may have the effect of discouraging, delaying or preventing a change
in control. Such Preferred Stock, among other things, may be used to create
voting impediments with respect to any changes in control or to dilute the
stock ownership of holders of common stock seeking to obtain control. See
"Risk Factors--Anti-Takeover Provision and our Right to Issue Preferred Stock
Could Make a Third-Party Aquisition of Us Difficult," "--Common Stock" and "--
Preferred Stock."     
 
Registration Rights
   
  After the consummation of the offering, the holders of warrants to purchase
235,871 shares of common stock or their transferees, holders of 9,734,846
shares of common stock issuable upon conversion of the preferred stock and
holders of 555,556 shares of common stock issuable upon conversion of the
convertible notes, assuming an initial public offering price of $9.00 per
share will be entitled to certain registration rights with respect to the
registrable securities. These rights are provided under the terms of the
registrable securities and     
 
                                      65

agreements between us and the holders of such securities. Such agreements and
registrable securities provide, in certain instances, demand registration
rights. In addition, pursuant to these agreements, the holders are entitled,
subject to certain limitations, to require us to include their registrable
securities in future registration statements we file under the Securities Act
of 1933. In accordance with the terms of such piggyback registration rights, we
have elected to exclude all registrable securities from the offering. The
Holders also are entitled, subject to certain limitations, to require us to
register their registrable securities on a registration statement on Form S-3
once we are eligible to use a Form S-3 in connection with such registrations.
However, Holders of all of these shares will be restricted from exercising such
rights until 180 days after the date of this prospectus. Registration of shares
of common stock pursuant to the exercise of demand registration rights,
piggyback registration rights or S-3 registration rights under the Securities
Act of 1933 would result in such shares becoming freely tradable without
restriction under the Securities Act of 1933 immediately upon the effectiveness
of such registration. "Risk Factors--Shares Eligible for Future Sale By Our
Current Shareholders May Adversely Affect Our Stock Price," "Shares Eligible

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Sales of substantial amounts of common stock in the public market following
the offering could adversely affect the market price of the common stock and
adversely affect our ability to raise capital at a time and on terms favorable
to us.
   
  Of the 16,424,783 shares to be outstanding after the offering (assuming that
the underwriters do not exercise their over-allotment option), the 3,500,000
shares of common stock offered hereby and an additional 942,723 shares of
common stock will be freely tradeable without restriction in the public market
unless such shares are held by "affiliates," as that term is defined in Rule
144(a) under the Securities Act of 1933. For purposes of Rule 144, an
"affiliate" of an issuer is a person that, directly or indirectly through one
or more intermediaries, controls, or is controlled by or is under common
control with, such issuer. The remaining      shares of common stock to be
outstanding after the offering are "restricted securities" under the Securities
Act of 1933 and may be sold in the public market upon the expiration of certain
holding periods under Rule 144, subject to the volume, manner of sale and other
limitations of Rule 144.     
   
  In general, under Rule 144 as currently in effect, a person who has
beneficially owned shares for at least two years, including an "affiliate," as
that term is defined in the Securities Act, is entitled to sell, within any
three-month period, a number of shares that does not exceed the greater of:
       
 . one percent of the then outstanding shares of our common stock
   (approximately 164,204 shares immediately following the offering), or     
    
 . the average weekly trading volume during the four calendar weeks preceding
   filing of notice of such sale. Sales under Rule 144 are also subject to
   certain manner of sale provisions, notice requirements and the availability
   of current public information about us. A shareholder who is deemed not to
   have been an "affiliate" of ours at any time during the 90 days preceding a
   sale, and who has beneficially owned restricted shares for at least two
   years, would be entitled to sell such shares under Rule 144(k) without
   regard to the volume limitations, manner of sale provisions or public
   information requirements.     
   
  In addition, as of December 31, 1998, there were outstanding warrants to
purchase 235,871 shares of common stock and options to purchase 2,083,861
shares of common stock, of which 366,162 options were fully vested and
exercisable. An additional 5,754 shares were reserved for issuance under our
equity compensation plan. We intend to register the shares of common stock
issued, issuable or reserved for issuance under the plan as soon as practicable
following the date of this prospectus.     
   
  Holders of warrants to purchase 235,871 shares of common stock, holders of
9,307,495 shares of common stock issuable upon conversion of the preferred
stock and holders of 555,556 shares of common stock issuable upon conversion of
the convertible notes, assuming an initial public offering price of $9.00 per
share, are entitled to registration rights with respect to such shares for
resale under the Securities Act. If such holders, by exercising their
registration rights, cause a large number of shares to be registered and sold
in the public market, such sales could have an adverse effect on the market
price for the common stock. Such rights may not be exercised prior to the
expiration of 180 days from the date of this

  The underwriting agreement provides that the underwriters' obligations to
purchase shares of common stock are subject to certain conditions, and that if
any of the foregoing shares of common stock are purchased by the underwriters
pursuant to an Underwriting Agreement, then all of the shares of common stock
which the underwriters have agreed to purchase pursuant to the underwriting
agreement, must be so purchased.     
   
  The representatives have advised us that the underwriters propose to offer
the shares of common stock directly to the public at the public offering price
set forth on the cover page of this prospectus, and to certain selected
dealers, who may include the underwriters, at such public offering price less a
selling concession not in excess of $   per share. The underwriters may allow,
and the selected dealers may reallow, a concession not in excess of $   per
share to certain brokers and dealers. After the offering, the underwriters may
change the offering price and other selling terms.     
   
  We have granted to the underwriters an option to purchase up to an aggregate
of 525,000 additional shares of common stock, exercisable solely to cover over-
allotments, if any, at the public offering price less the underwriting
discounts and commissions shown on the cover page of this prospectus. Such
option may be exercised at any time until 30 days after the date of the
underwriting agreement. To the extent that such option is exercised, each
underwriter will be committed, subject to certain conditions, to purchase a
number of additional shares of common stock proportionate to such underwriter's
initial commitment as indicated in the preceding table and we will be
obligated, under such over-allotment option, to sell such shares of common
stock to the underwriters.

  We have agreed that, without the prior consent of Lehman Brothers, we will
not, except for certain limited exceptions, directly or indirectly, offer, sell
or otherwise dispose of any shares of common stock or any securities which may
be converted into or exchanged for any such shares of common stock for a period
of 180 days from the date of this prospectus. All of our executive officers and
directors and certain other shareholders have agreed pursuant to lock-up
agreements that, without the prior written consent of Lehman Brothers, they
will not, except for in certain limited exceptions, directly or indirectly,
offer, sell or otherwise dispose of any shares of common stock or any
securities which may be converted into or exchanged for any such shares for the
period ending 180 days after the date of this prospectus. See "Shares Eligible
for Future Sale."     
   
  Prior to the offering, there has been no public market for the shares of
common stock. The initial public offering price will be negotiated between the
representatives and us. In determining the initial public offering price of the
common stock, the representatives will consider, among other things and in
addition to prevailing market conditions, our historical performance and
capital structure, estimates of our business potential and earning prospects,
an overall assessment of our management and the consideration of the above
factors in relation to market valuation of companies in related businesses.
    
  Application has been made to have the common stock approved for quotation on
the Nasdaq National Market under the symbol "VERT."
   
  We have agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act, and to contribute, under
certain circumstances, to payments that the underwriters may be required to
make in respect thereof.     
   
  Until the distribution of the common stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the underwriters
and certain selling group members to bid for and purchase shares of common
stock. As an exception to these rules, the representatives are permitted to
engage in certain transactions that stabilize the price of the common stock.
Such transactions may consist of bids or purchases for the purposes of pegging,
fixing or maintaining the price of the common stock.     
   
  If the underwriters create a short position in the common stock in connection
with the offering (i.e., they sell more shares than are set forth on the cover
page of this prospectus), the representatives may reduce that short position by
purchasing common stock in the open market. The representatives also may elect
to reduce any short position by exercising all or part of the over-allotment
option described herein. The underwriters have informed us that they do not
intend to confirm sales to discretionary accounts that exceed 5% of the total
number of shares of common stock offered by them.     
   
  The representatives also may impose a penalty bid on certain underwriters and
selling group members. This means that if the representatives purchase shares
of common stock in the open market to reduce the underwriters' short position
or to stabilize the price of the common stock, they may reclaim the amount of
the selling concession from the underwriters and selling group members who sold
those shares as part of the offering.     
 
  In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid might have an effect on the
 
                                       70

price of a security to the extent that it were to discourage resales of the
security by purchasers in an offering.
   
  Neither we nor any of the underwriters makes any representation or prediction
as to the direction or magnitude of any effect that the transactions described
above may have on the price of the common stock. In addition, neither we nor
any of the underwriters makes any representation that the representatives will
engage in such transactions or that such transactions, once commenced, will not
be discontinued without notice.     
 
  Any offers in Canada will be made only pursuant to an exemption from the
requirements to file a prospectus in the relevant province of Canada in which
such sale is made.
   
  Purchasers of the shares of common stock offered in this prospectus may be
required to pay stamp taxes and other charges under the laws and practices of
the country of purchase, in addition to the offering price listed on the cover
of this prospectus.     
   
  The representatives have informed us that they do not intend to confirm the
sales of shares of common stock offered in this prospectus to any accounts over
which they exercise discretionary authority.     
   
  At our request, the underwriters have reserved up to        shares of common
stock offered hereby for sale to certain of our officers, directors, employees,
business associates and related parties at the initial public offering price
set forth on the cover page of this prospectus. Such persons must commit to
purchase no later than the close of business on the day following the date of
this prospectus. The number of shares available for sale to the general public
will be reduced to the extent such persons purchase such reserved shares.     
   
  The underwriters, at the request of VerticalNet, have reserved for sale at
the initial public offering price up to     shares of common stock to visitors
and users of the VerticalNet services or to its Web site who express an
interest in purchasing such shares. The sale of such shares will be made by Wit
Capital acting as e-Manager in the offering. Purchases of the reserved shares
are to be made through an account at Wit Capital in accordance with Wit
Capital's procedures for opening an account and transacting in securities. Any
reserved shares not purchased by visitors and users of VerticalNet's services
or to its Web site will be offered by the underwriters on the same basis as
other shares offered in this prospectus.     
   
  A prospectus in electronic format is being made available on an Internet Web
site maintained by Wit Capital. In addition, pursuant to an e-Dealer Agreement,
all dealers purchasing shares from Wit Capital in the offering (the "e-
Dealers") similarly have agreed to make a prospectus in electronic format
available on Web sites maintained by each of the e-Dealers. The information on
such Web sites relating to the VerticalNet offering is filed as an exhibit to
the registration statement. Reference is made to the exhibit for a more
complete description of the information relating to the offering contained on
such Web sites.     
   
  Wit Capital, a member of the National Association of Securities Dealers,

  When the reverse stock spilt referred to in the last paragraph of Note 14 of

                          INDEPENDENT AUDITORS' REPORT
   
To the Board of Directors and Shareholders     
VerticalNet, Inc.:
   
  We have audited the accompanying consolidated balance sheets of VerticalNet,
Inc. and subsidiaries as of December 31, 1996 and 1997, and September 30, 1998
and the related consolidated statements of operations, shareholders' equity
(deficit) and cash flows for the period from July 28, 1995 (inception) to
December 31, 1995, for the years ended December 31, 1996 and 1997, and the nine
months ended September 30, 1998. These consolidated financial statements are
the responsibility of the Company's management. Our responsibility is to
express an opinion on these consolidated financial statements based on our
audits.     
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
   
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of
VerticalNet, Inc. and subsidiaries as of December 31, 1996 and 1997, and
September 30, 1998, and the results of their operations and their cash flows
for the period from July 28, 1995 (inception) through December 31, 1995, for
the years ended December 31, 1996 and 1997, and the nine months ended September
30, 1998 in conformity with generally accepted accounting principles.

(1) Summary of Significant Accounting Policies
 
 Description of Company
   
  VerticalNet, Inc. (VerticalNet or the Company) is an owner and operator of
vertical trade communities, which are targeted business-to-business communities
of commerce on the Internet. The Company's vertical trade communities are Web
sites that act as industry-specific comprehensive sources of information,
interaction and electronic commerce. Vertical trade communities combine product
information; industry news; requests for proposals; directories; classifieds;
job listings; discussion forums; a variety of electronic commerce opportunities
for buyers and sellers; and other services, such as online professional
education courses and virtual trade shows. Each trade community is individually
branded, focuses on one business sector and caters to individuals with similar
professional interests. The virtual trade communities are designed to attract
technical and purchasing professionals with highly specialized product and
specification requirements and purchasing authority or influence. The Company
was founded on July 28, 1995 and as of September 30, 1998 operates 29 vertical
trade communities in seven major industry groups: environmental; electronics;
services; communications; process industries; sciences; and food & packaging.
    
  The Company currently generates substantially all of its revenue from
Internet advertising including the development of "storefronts" (Web pages that
focus on advertisers products and provide a link to the advertisers Web sites).
   
  Internet Capital Group LLC (ICG) has a majority of the voting securities of
the Company through its ownership of preferred stock of the Company.     
 
  The Company has sustained significant net losses and negative cash flows from
operations since its inception. The Company's ability to meet its obligations
in the ordinary course of business is dependent upon its ability to establish
profitable operations or raise additional financing through public or private
equity financing, bank financing, or other sources of capital. During 1998 the
Company sold an additional $15.2 million of its preferred stock. Management
believes that its current funds combined with other available sources of
funding will be sufficient to enable the Company to meet its planned
expenditures through at least December 31, 1998. If financial resources are not
sufficient, management has the intent and believes it has the ability to reduce
expenditures as to not require additional financial resources if such resources
are not available on terms acceptable to the Company.
 
 Unaudited Interim Financial Information
   
  The interim financial statements of the Company for the nine months ended
September 30, 1997, included herein, have been prepared by the Company, without
audit, pursuant to the rules and regulations of the SEC. Certain information
and footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to such rules and regulations relating to interim financial
statements.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
          
       (Information with respect to September 30, 1997 is unaudited)     
   
In the opinion of management, the accompanying unaudited interim financial
statements reflect all adjustments, consisting only of normal recurring
adjustments, necessary to present fairly the results of the Company's
operations and its cash flows for the nine months ended September 30, 1997. The
accompanying unaudited interim financial statements are not necessarily
indicative of full year results.     
 
 Principles of Consolidation
 
  The consolidated financial statements include the financial statements of the
Company and its wholly owned subsidiaries. All significant intercompany
balances and transactions have been eliminated in consolidation.
 
 Cash and Cash Equivalents
 
  The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.
 
 Property and Equipment
 
  Property and equipment are stated at cost, net of accumulated amortization
and depreciation. Leasehold improvements are amortized on a straight-line basis
over the lesser of the estimated useful life of the asset or the lease term.
Property and equipment are depreciated on a straight-line basis over the
estimated useful lives of the assets as follows:

      Computer equipment and purchased software......................... 3 years
      Office equipment and furniture.................................... 5 years
      Trade show equipment.............................................. 7 years
      Leasehold improvements............................................ 3 years
</TABLE>
 
 Revenue and Editorial and Operational Expenses
 
  The Company's revenues are derived principally from advertising contracts
which include the initial construction of storefronts. The advertising
contracts do not extend beyond one year. Advertising revenues are recognized
ratably over the period of the advertising contract.
 
  Revenues from educational courses are recognized in the period in which the
course is completed and revenues from the sale of books are recognized in the
period in which the books are shipped.
   
  Barter transactions are recorded at the lower of estimated fair value of the
goods or services received or the estimated fair value of the advertisements
given. From July 28, 1995 (inception) through the year ended December 31, 1997,
barter transactions have been immaterial. For the nine months ended September
30, 1998, the Company recognized approximately $351,000 of advertising revenues
from barter transactions.

       (Information with respect to September 30, 1997 is unaudited)     
   
  Editorial and operational expenses primarily consist of Internet connection
charges, depreciation, purchased content, salaries and benefits of operating
and editorial personnel, and other related operating costs.     
 
 Concentration of Credit Risk
 
  The Company performs ongoing credit evaluations of its customers' financial
condition and generally does not require collateral on accounts receivable. The
Company maintains allowances for credit losses and such losses have been within
management's expectations. No single customer accounted for greater than 10% of
total revenues during the period from July 28, 1995 (inception) through
December 31, 1995 and the years ended December 31, 1996 and 1997 and the nine
month periods ended September 30, 1997 and 1998.
 
 Financial Instruments
 
  The Company's financial instruments principally consist of cash, accounts
receivable, accounts payable, loans payable and capital lease obligations that
are carried at cost which approximates fair value.
 
 Product Development
 
  Product development costs consists principally of salaries and related costs,
which are charged to expense as incurred.
 
 Advertising Costs
   
  The Company charges advertising costs to expense as incurred. Advertising
expense was approximately $38,000, $21,000 and $198,000 for the period from
July 28, 1995 (inception) through December 31, 1995 and the years ended
December 31, 1996 and 1997, respectively, and $126,000 and $1,323,000 for the
nine months ended September 30, 1997 and 1998, respectively.     
 
 Income Taxes
 
  The Company records income taxes using the asset and liability method.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and the tax effect of net operating loss carryforwards. Deferred tax
assets and liabilities are measured using enacted tax rates expected to apply
to taxable income in the years in which those temporary differences are
expected to be recovered or settled. The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in income in the period that
includes the enactment date. A valuation allowance is recorded against deferred
tax assets if it is more likely than not that such assets will not be realized.

 Accounting for Impairment of Long-Lived Assets
 
  The Company records impairment losses on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount.
 
 Goodwill and Intangibles
 
  Goodwill is amortized using the straight-line method from the date of
acquisition over the expected period to be benefited, estimated at 36 months.
The Company periodically assesses the recoverability of goodwill, as well as
other long-lived assets, based upon expectations of future undiscounted cash
flows.
 
 Deferred Offering Costs
   
  As of September 30, 1998, specific incremental costs directly attributable
to the planned initial public offering (IPO) process have been deferred. These
costs will be charged against additional paid-in-capital in connection with
the consummation of this offering.     
 
 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
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Stock Options
 
  The Company accounts for the grant of employee options to purchase common
stock in accordance with Statement of Financial Accounting Standards No. 123,
Accounting for Stock-Based Compensation (SFAS No. 123). SFAS 123 gives
companies the option to adopt the fair value method for expense recognition of
employee stock options or to continue to account for stock options and stock-
based awards using the intrinsic value method, as outlined under Accounting
Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB
25) and to make pro forma disclosures of net loss as if the fair value method
had been applied. The Company elected to apply APB 25 to account for stock
options and has disclosed the pro forma net loss as if the fair value method
had been applied.
 
 Stock Splits
 
  In February 1996 and February 1997, the Company's Board of Directors
authorized and implemented an 11,008 for one and a 4.7619-for-one, stock
split, respectively. All share amounts have been retroactively restated to
reflect these events in the accompanying financial statements.

 Computation of Historical Net Loss Per Share and Pro Forma Net Loss Per Share
 
  The Company adopted Computation of Earnings Per Share, (SFAS No. 128), during
the year ended December 31, 1997. In accordance with SFAS No. 128, basic
earnings per share is computed using the weighted average number of common
shares outstanding during the period. Dilutive earnings per share is computed
using the weighted average number of common and dilutive common equivalent
shares outstanding during the period. Common equivalent shares consist of the
incremental common shares issuable upon the exercise of stock options and
warrants (using the treasury stock method) and the incremental common shares
issuable upon the conversion of the convertible preferred stock (using the if-
converted method). Common equivalent shares are excluded from the calculation
if their effect is anti-dilutive. Pursuant to SEC Staff Accounting Bulletin No.
98, common stock and convertible preferred stock issued for nominal
consideration, prior to the anticipated effective date of an IPO, are required
to be included in the calculation of basic and diluted net loss per share as if
they were outstanding for all periods presented. To date, the Company has not
had any issuances or grants for nominal consideration.
 
  Pro forma net loss per share is computed using the weighted average number of
shares of common stock outstanding, including common equivalent shares from the
convertible preferred stock (using the if-converted method), which will
automatically convert into common stock upon an IPO as if converted at the
original date of issuance, for both basic and diluted net loss per share, even
though inclusion is antidilutive.
 
  The following table sets forth the computation of loss per share:

 Recent Accounting Pronouncements
 
  In June 1997 the Financial Accounting Standards Board (FASB) issued Reporting
Comprehensive Income (SFAS No. 130), which establishes standards for reporting
and display of comprehensive income and its components in the financial
statements. SFAS No. 130 is effective for fiscal years beginning after December
15, 1997. Reclassification of financial statements for earlier periods provided
for comparative purposes is required. SFAS No. 130 offers alternatives for
presentation of disclosures required by the standard. The adoption of SFAS No.
130 had no impact on the Company's results of operations, financial position or
cash flows, as the amount of comprehensive loss is the same as the net loss for
all periods presented.
 
  In June 1997 the FASB issued Disclosures about Segments of an Enterprise and
Related Information (SFAS No. 131), which establishes standards for reporting
information about operating segments in annual financial statements. It also
establishes standards for related disclosures about products and services,
geographic areas and major customers. SFAS No. 131 is effective for fiscal
years beginning after December 15, 1997. The adoption of SFAS No. 131 will not
have an impact on the Company's results of operations, financial position or
cash flows.
 
  In February 1998 the FASB issued Employers' Disclosures about Pension and
Other Postretirement Benefits (SFAS No. 132), which revises employers'
disclosures about pension and other postretirement benefit plans. SFAS No. 132
does not change the measurement or recognition of those plans. SFAS No. 132 is
effective for fiscal years beginning after December 15, 1997. The adoption of
SFAS No. 132 will not have an impact on the Company's results of operations,
financial position or cash flows.
 
  In March 1998 the American Institute of Certified Public Accountants (AICPA)
issued Statement of Position 98-1, Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use (SOP 98-1). SOP 98-1 is effective for
financial statements for years beginning after December 15, 1998. SOP 98-1
provides guidance on accounting for computer software developed or obtained for
internal use including the requirement to capitalize specified costs and
amortization of such costs. The Company does not expect the adoption of this
standard to have a material effect on the Company's capitalization policy.
 
  In April 1998 the AICPA issued Statement of Position 98-5, Reporting on the
Costs of Start-Up Activities (SOP 98-5). SOP 98-5, which is effective for
fiscal years beginning after December 15, 1998, provides guidance on the
financial reporting of start-up costs and organization costs. It requires costs
of start up activities and organization costs to be expensed as incurred. As
the Company has expensed these costs historically, the adoption of this
standard is not expected to have a significant impact on the Company's results
of operations, financial position or cash flows.
 
  In June 1998 the FASB issued Accounting for Derivatives and Hedging
Activities (SFAS 133), which establishes accounting and reporting standards for
derivative instruments, including certain

derivative instruments embedded in other contracts (collectively referred to as
derivatives) and for hedging activities. SFAS No. 133 is effective for all
fiscal quarters of fiscal years beginning after June 15, 1999. As the Company
does not currently engage or plan to engage in derivative or hedging
activities, there will be no impact to the Company's results of operations,
financial position or cash flows upon the adoption of this standard.
 
(2) Unaudited Pro Forma Balance Sheet
   
  The Company is planning on filing a registration statement with the
Securities and Exchange Commission (SEC) that would permit the Company to sell
shares of the Company's common stock in connection with a proposed IPO. In
addition, in November of 1998, the Company obtained $5.0 million of convertible
notes from ICG and certain holders of the Series D preferred stock and a $2.0
million note from a bank.     
 
  The unaudited pro forma balance sheet as of September 30, 1998 reflects:
     
  (a) The Company's capitalization, if the IPO is consummated under terms
      presently anticipated. Upon closing of the proposed IPO, all of the
      then outstanding shares of the Company's convertible preferred stock
      will automatically convert into 9,734,846 shares of common stock on the
      basis that the Series A preferred stock converts to shares of common
      stock on a ratio of 4.7619:1 and the Series B, C and D preferred stock
      converts on a ratio of 1:1. The conversion of the convertible preferred
      stock has been reflected in the accompanying unaudited pro forma
      consolidated balance sheet as if it had occurred on September 30, 1998.
             
  (b) The $5.0 million of convertible notes from ICG and certain holders of
      the Series D preferred stock that convert into shares of common stock
      at the consumation of the IPO and the $2.0 million note from a bank as
      more fully described in Note 14. In connection with these loans the
      Company issued warrants to purchase an aggregate of 102,564 shares of
      the Company's common stock with an estimated fair value of $200,000.
          
(3) Acquisitions
   
  In September 1998 the Company acquired all of the outstanding capital stock
of Boulder Interactive Technology Services Company (BITC) for $1.8 million in
cash. BITC operates a vertical trade community for professionals in the radio
frequency and wireless communications industry. The acquisition was accounted
for using the purchase method of accounting. The excess of the purchase price
over the fair value of the net assets acquired of approximately $1,864,000 was
recorded as goodwill and is being amortized over 36 months.     
   
  In September 1998 the Company acquired all of the outstanding capital stock
of Informatrix Worldwide, Inc. (Informatrix) for 46,154 shares of the Company's
common stock valued at $153,000. Informatrix operates a vertical community in
the property and casualty insurance industry that caters to risk managers,
agents, brokers and other professionals in the insurance industry. The
acquisition was accounted for under the purchase method of accounting. The
estimated excess of the purchase price over the fair value of the net assets
acquired of approximately $903,000 was recorded

as goodwill and will be amortized over 36 months. The purchase agreement also
provides for the Company to issue up to 11,538 additional shares of the
Company's common stock to the Informatrix shareholders in the event that
Informatrix achieves certain sales targets through December 1998. As of October
31, 1998, the former shareholders of Informatrix earned 2,200 shares of common
stock which was valued at $7,293. The additional consideration was accounted
for as additional goodwill.     
   
  The following unaudited pro forma financial information presents the combined
results of operations of VerticalNet, BITC and Informatrix as if the
acquisitions occurred on January 1, 1997, after giving effect to certain
adjustments including amortization of goodwill. The unaudited pro forma
financial information does not necessarily reflect the results of operations
that would have occurred had VerticalNet, BITC and Informatrix constituted a
single entity during such periods.

(5) Line of Credit
 
  The Company had a line of credit with a bank in the amount of $2,500,000 at
December 31, 1997. Borrowings under the facility were collateralized by a
security interest in all assets of the Company and required the Company to meet
specified financial ratios. As of December 31, 1997, the Company was in
technical default, as it did not meet the specified financial ratios. The bank
waived these violations for the year ended December 31, 1997. The facility
bears interest at prime plus 1.5% (10% at December 31, 1997). The weighted
average interest rate for borrowings under this facility was 10% for the year
ended December 31, 1997. In connection with obtaining these facilities, the
Company issued warrants to purchase its common stock (Note 9). ICG has
guaranteed repayment of $2.0 million under the line of credit agreement. The
Company repaid all amounts outstanding under

this facility in May 1998 and consequently, the guarantee from ICG was
cancelled. Subsequently, the bank provided a $500,000 line of credit, which
expires on June 30, 1999 and is collateralized by a security interest in all of
the assets of the Company with an interest rate prime plus 1.5%.

  The Company has entered into non-cancelable obligations with several content
service providers and Internet search engines. Under these agreements,
exclusive of the Excite agreement discussed above, the Company's obligations
are as follows:

  The Company has entered into employment agreements with several employees.
The agreements are cancelable, but require severance upon termination. As of
December 31, 1997, the Company would be required to pay approximately $950,000
in severance (of which $500,000 has been guaranteed by ICG) in the event that
these employment agreements are cancelled. As part of the employment agreement
with the Company's president and chief executive officer, the Company had
committed to grant options to purchase 6% of the Company's common stock.
Pursuant to this agreement, the Company granted 307,692, 196,481 and 231,530
options in October 1997, January 1998 and June 1998, respectively, at an
exercise price of $0.80, $0.80 and $2.63, respectively, which was the then fair
value of the Company's common stock. At September 30, 1998, the Company has
satisfied its obligations under this agreement.     
 
  The Company is a party to legal proceedings and claims, which arise in the
ordinary course of business. In the opinion of management, the amount of the
ultimate liability with respect to these actions will not materially affect the
financial position, results of operations or cash flows of the Company.
 
 
(9) Capital Stock
   
  The Company's restated Articles of Incorporation provides the Company with
the authority to issue 40,000,000 shares of common stock and 40,000,000 shares
of preferred stock.     
 
 Preferred Stock
   
  In September 1996 the Company sold 512,821 shares of Series A preferred stock
(Series A) for $1,000,000. In July 1997 the Company sold 2,579,580 shares of
Series B preferred stock (Series B) for $2,000,000. In October 1997 the Company
sold 154,861 shares of Series C preferred stock (Series C) for $200,000.     
   
  On May 11, 1998 and June 10, 1998, the Company sold 3,988,604 and 569,801
shares of Series D preferred stock (Series D), respectively, for an aggregate
amount of approximately $15.2 million. If the Company does not complete an IPO
as defined, by May 1, 2000, the Series D has a cumulative dividend rate equal
to 6% of the original purchase price ($3.51 per share) which is due and payable
on May 1, 2000. Thereafter, the Series D cumulative dividends will continue to
accrue and are payable quarterly until the closing of an IPO. The holders of
the Series D preferred have demand and piggy-back registration rights as
defined.

  Holders of preferred stock have the option to convert such shares into shares
of common stock on a 1:1 ratio, except for the Series A preferred stock which
converts on a ratio of 4.7619:1. The conversion rate on a particular series of
preferred stock is subject to an adjustment in the event that any additional
common stock, or other shares convertible into common stock, are issued for a
per share price less than the particular series conversion price. Mandatory
conversion occurs upon the closing of an IPO of the Company's common stock, as
defined. The Series D is senior to the Company's Series A, Series B and Series
C in liquidation and the holders of Series A, Series B and Series C are
entitled to receive an amount equal to their respective redemption price prior
to the distribution to the common shareholders.
   
  The preferred stock votes on an as if converted basis. The Series A, Series B
and Series C, together have the right to elect two directors of the Company and
the Series D holders have the right to elect two directors of the Company. The
holders of preferred stock have no right to elect or appoint directors after
the shares convert into common stock upon the closing of an IPO.     
 
  Preferred stock consists of the following at December 31, 1996, 1997 and
September 30, 1998:

March 1998 the Company issued an additional warrant to ICG to purchase a
maximum of 77,430 shares of common stock at an exercise price of $1.29 per
share. The warrants were issued in connection with certain guarantees of the
Company's bank debt by ICG. The exercise price and number of shares are subject
to adjustment, based upon the Company's next round of equity financing. The
warrant expires on November 30, 2008.     
   
  In May 1998 in connection with the Company's equity financing, the Company
cancelled the warrants issued to ICG and its bank in December 1997 and issued
new warrants to purchase an aggregate of 113,960 shares of common stock at an
exercise price of $3.51 per share.     
 
  The estimated fair value of the warrants issued to the Company's bank and ICG
is $50,000 and was recorded as interest expense in the accompanying statement
of operations for the year ended December 31, 1997.
 
(10) Stock Option Plan
   
  In December 1996 the Company's Board of Directors adopted the 1996 stock
option plan (the Plan). A total of 615,385 shares of common stock were reserved
for issuance under this Plan and this amount was increased to 1,846,154 in
January 1998 and 2,025,641 in August 1998.     
 
  The exercise price for the options is determined by the Board of Directors,
but shall not be less than 100% of the fair market value of the common stock on
the date the option is granted. Generally, the options vest over a four-year
period after the date of grant and expire ten years after the date of grant.
Option holders that terminate their employment with the Company generally
forfeit all non-vested options. Employees, key advisors and non-employee
directors of the Company are eligible to receive awards under the Plan.
 
  The following table summarizes the activity of the Company's stock option
plan:

(12) Income Taxes
 
  Prior to June 1996, the Company elected to be treated for federal income tax
purposes as an S Corporation under Subchapter S of the Internal Revenue Code
(the Code). As a result, the Company's earnings for prior tax years and through
September 12, 1996, the date of termination of the Company's S Corporation
status (the termination date) had been taxed for federal income tax purposes
directly to the Company's shareholders, rather than to the Company.
   
  The components of the net deferred tax assets as of December 31, 1996 and
1997 and September 30, 1998 consists of the following:

</TABLE>    
   
  Deferred income taxes reflect the net tax effects of temporary differences
between carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. In assessing the
realizability of deferred tax assets, management considers whether it is more
likely than not that some portion or all of the deferred tax assets will not be
realized. The ultimate realization of deferred tax assets is dependent upon the
generation of future taxable income during the periods in which temporary
differences representing net future deductible amounts become deductible. Due
to the uncertainty of the Company's ability to realize the benefit of the
deferred tax assets, the deferred tax assets are fully offset by a valuation
allowance at December 31, 1996 and 1997 and September 30, 1998.     
   
  As of September 30, 1998, the Company has approximately $12,367,000 of net
operating loss carryforwards for federal tax purposes. These carryforwards will
begin expiring in 2013 if not utilized. In addition, the Company has net
operating loss carryforwards in certain states with various expiration periods
beginning in 2000.     
 
  Under the Tax Reform Act of 1986, the utilization of a corporation's net
operating loss carryforward is limited following a greater than 50% change in
ownership. Due to the Company's prior and current equity transactions, the
Company's net operating loss carryforwards may be subject to an annual
limitation. Any unused annual limitation may be carried forward to future years
for the balance of the net operating loss carrryforward period.
 
(13) Informatrix Worldwide, Inc.

for $20,000 per month, until either the Company or Informatrix terminated the
agreement. The Company substantially completed all of its obligations under the
development portion of the contract as of December 31, 1997, but deferred
recognition of revenue until the amounts were deemed collectible from
Informatrix. No revenue was recorded by the Company under the above contracts
in 1997 and 1998. Such development costs were charged to expense, as incurred.
    
  In addition, the Company advanced Informatrix $160,000 in 1997, as evidenced
by a demand note. The Company had provided a reserve of $80,000 against this
note. The note is unsecured and bears interest at prime plus 1.5% (10% at
December 31, 1997).
 
  During the nine months ended September 30, 1998, the Company advanced an
additional $555,000 to Informatrix.

To the Board of Directors
Boulder Interactive Technology Services Company:
 
  We have audited the accompanying balance sheets of Boulder Interactive
Technology Services Company d/b/a Microwave Online Services Company and RF
Globalnet as of December 31, 1996 and 1997 and the related statements of
operations, shareholders' equity and cash flows for the period from March 22,
1996 (inception) through December 31, 1996 and for the year ended December 31,
1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Boulder Interactive Technology
Services Company d/b/a Microwave Online Services Company and RF Globalnet as of
December 31, 1996 and 1997, and the results of its operations and its cash flow
for the period from March 22, 1996 (inception) through December 31, 1996 and
for the year ended December 31, 1997 in conformity with generally accepted
accounting principles.

(1) Summary of Significant Accounting Policies
 
  Boulder Interactive Technology Services Company (d/b/a Microwave Online
Services Company and RF Globalnet) (the Company) was formed in March 1996. The
Company operates a Vertical trade community for professionals in the radio
frequency and wireless communications industry. This Web Site gives engineers
access to the latest product and technical information, leading edge education
resources, expert-hosted technical forums and career opportunities in the
field.
 
 Property and Equipment
 
  Property and equipment are stated at cost, net of depreciation. Property and
equipment are depreciated on a straight-line basis over the estimated useful
lives of the assets (three to five years).
 
 Revenue and Cost Recognition
 
  The Company's advertising revenues are derived principally from advertising
contracts which generally do not extend beyond one year. Advertising revenues
are recognized ratably over the term of the contract. Online courses, book
sales and other revenues are generally recognized upon delivery provided that
no significant Company obligations remain and collection of the receivable is
probable. In cases where there are significant remaining obligations, the
Company defers such revenues until those obligations are satisfied.
   
  Barter transactions are recorded at the lower of estimated fair value of the
goods or services received or the estimated fair value of the advertisements
given. Revenue recorded under barter transactions for the year ended December
31, 1997 was $30,000 and $0 and $51,600 for the six months ended June 30, 1997
and 1998, respectively.     
   
  Editorial and operational expenses primarily consist of Internet connection
charges, depreciation, purchased content, salaries and benefits of operating
and editorial personnel and other related operating costs.     
 
 Concentration of Credit Risk
 
  The Company does not require collateral on accounts receivable. The Company
maintains allowances for credit losses and such losses have been within
management's expectations. No single customer accounted for greater than 10% of
total revenues for the period from March 22, 1996 (inception) through December
31, 1996 and for the year ended December 31, 1997.
 
 Advertising Costs
   
  The Company expenses advertising costs as incurred. For the period from March
22, 1996 (inception) through December 31, 1996 and for the year ended December
31, 1997 and for the six months ended June 30, 1997 and 1998, advertising
expense was approximately $1,600, $34,000, $2,500 and $59,000, respectively.

     (Information with respect to June 30, 1997 and 1998 is unaudited)     
 
 Income Taxes
 
  Effective January 1, 1998, the Company records income taxes using the asset
and liability method. Deferred tax assets and liabilities are recognized for
the future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases and the tax effect of net operating loss carryforwards.
Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date.
 
 Accounting for Impairment of Long-Lived Assets
 
  In accordance with Statement of Financial Accounting Standards No. 121, the
Company records impairment losses on long-lived assets used in operations when
indicators of impairment are present and the undiscounted cash flows estimated
to be generated by those assets are less than the assets' carrying amount.
 
 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 disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
 Financial Instruments
 
  The Company's financial instruments principally consist of cash, accounts
receivable, accounts payable and a loan payable that are carried at cost which
approximates fair value.
 
 Recent Accounting Pronouncements
 
  In June 1997 the Financial Accounting Standards Board (FASB) issued Reporting
Comprehensive Income (SFAS No. 130), which establishes standards for reporting
and display of comprehensive income and its components in the financial
statements. SFAS No. 130 is effective for fiscal years beginning after December
15, 1997. Reclassification of financial statements for earlier periods provided
for comparative purposes is required. SFAS No. 130 offers alternatives for
presentation of disclosures required by the standard. The adoption of SFAS No.
130 had no impact on the Company's results of operations, financial position or
cash flows.
 
  In June 1997 the FASB issued Disclosures about Segments of an Enterprise and
Related Information (SFAS No. 131), which establishes standards for reporting
information about operating

segments in annual financial statements. It also establishes standards for
related disclosures about products and services, geographic areas and major
customers. SFAS No. 131 is effective for fiscal years beginning after December
15, 1997. The adoption of SFAS No. 131 will not have an impact on the Company's
results of operations, financial position or cash flows.
 
  In February l998 the FASB issued Employers' Disclosures about Pension and
Other Postretirement Benefits (SFAS No. 132), which revises employers'
disclosures about pension and other postretirement benefit plans. SFAS No. 132
does not change the measurement or recognition of those plans. SFAS No. 132 is
effective for fiscal years beginning after December 15, 1997. The adoption of
SFAS No. 132 will not have an impact on the Company's results of operations,
financial position or cash flows.
 
  In March l998 the American Institute of Certified Public Accounts (AICPA)
issued Statement of Position 98-1, Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use (SOP 98-1). SOP 98-1 is effective for
financial statements for years beginning after December 15, 1998. SOP 98-1
provides guidance over accounting for computer software developed or obtained
for internal use including the requirement to capitalize specified costs and
amortization of such costs. The Company does not expect the adoption of this
standard to have a material effect on the Company's capitalization policy.
 
  In April 1998 the AICPA issued Statement of Position 98-5, Reporting on the
Costs of Start-Up Activities (SOP 98-5). SOP 98-5, which is effective for
fiscal years beginning after December 15, 1998, provides guidance on the
financial reporting of start-up costs and organization costs. It requires costs
of start up activities and organization costs to be expensed as incurred. As
the Company has expensed these costs historically, the adoption of this
standard is not expected to have a significant impact on the Company's results
of operations, financial position or cash flows.
 
 Stock Options
 
  The Company accounts for the grant of employee options to purchase common
stock in accordance with Statement of Financial Accounting Standards No. 123,
Accounting for Stock-Based Compensation (SFAS No. 123). This statement gives
companies the option to adopt the fair value method for expense recognition of
employee stock options or to continue to account for stock options and stock-
based awards using the intrinsic value method, as outlined under Accounting
Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB
25), and to make pro forma disclosures of net loss as if the fair value method
had been applied. The Company elected to apply APB 25 to account for stock
options and disclose the pro forma net loss as if the fair value method had
been applied (Note 5).

  Rent expense under this noncancelable operating lease was approximately
$7,600 and $17,000 for the period from March 22, 1996 (inception) through
December 31, 1996 and for the year ended December 31, 1997, respectively and
$8,800 and $9,200 for the six months ended June 30, 1997 and 1998,
respectively.     
 
  In addition, the Company has an advertising commitment from the period August
1998 through December 1998, totaling approximately $10,000.
 
(4) Stock Option Plan
   
  In July 1998 the Company's board of directors adopted the 1998 stock option
plan (the 1998 Plan). A total of 80,000 shares of common stock were reserved
for issuance under this Plan.     
   
  The exercise price and the vesting period for the options is determined by
the board of directors. All options expire ten years after the date of grant.
On January 8, 1998, options for 9,750 shares of common stock were granted,
outside of the 1998 Plan, at an exercise price of $0.60 that vested
immediately. Compensation expense of $22,150 was recorded for these options as

to a non-employee of the Company. On July 2, 1998, options for 15,832 shares of
common stock were granted at an exercise price of $0.60, under the 1998 Plan,
that vest over a four-year period. Compensation expense of $47,700 was recorded

1998 as the vesting on these options was accelerated due to the Company being
acquired in September 1998 (Note 6).

January 1, 1998. Prior to that election, the Company was an "S" corporation.

  On September 1, 1998, the Company was acquired by VerticalNet, Inc.
(VerticalNet). Under the terms of that transaction, VerticalNet acquired all of

(1) Organization
   
  Informatrix Worldwide, Inc. (the Company) was formed in October 15, 1997. The
Company operates a vertical trade community in the property and casualty
insurance industry that caters to risk managers, agents, brokers and other
professionals in the insurance industry. A vertical trade community is a Web
site that acts as a source of information and dialogue for a particular
vertical market.     
 
(2) Summary of Significant Accounting Policies
 
 Computer Equipment
   
  Computer equipment are stated at cost, net of accumulated amortization and
depreciation. Property and equipment are depreciated on a straight-line basis
over the estimated useful lives of the assets (three years). Expenditures for
maintenance and repairs are charged to expense as incurred.     
 
 Revenue and Cost Recognition
   
  The Company's advertising revenues are derived principally from advertising
contracts which generally do not extend beyond one year. Advertising revenues
are recognized ratably over the term of the contract.     
   
  Editorial and operational costs include editorial costs which are principally
payroll and related costs.     
 
 Product Development
   
  Product development costs consists principally of salaries and related costs,
which are expensed as incurred.     
 
 Advertising Costs
   
  The Company expenses advertising costs as incurred. Advertising expense was
$0 for the period from October 15, 1997 (inception) to December 31, 1997 and
approximately $57,126 for the nine months ended September 30, 1998.     
   
 Income Taxes     
   
  Income taxes are accounted for using an asset and liability approach which
requires the recognition of taxes payable or refundable for the current year
and deferred tax liabilities and assets for the future tax consequences of
events that have been recognized in the Company's financial

statements or tax returns. The measurement of current and deferred tax
liabilities and assets are based on provisions of the enacted tax laws; the
effects of future changes in tax laws or rates are not anticipated. The
measurement of deferred tax assets is reduced, if necessary, by the amount of
any tax benefits that, based on available evidence, are not expected to be
realized.
 
  No federal or state income taxes are due as of December 31, 1997. The net
deferred tax asset, primarily related to net operating losses, is fully offset
by a valuation allowance at December 31, 1997.
 
 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 disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
 Financial Instruments
 
  The Company's financial instruments principally consist of cash, accounts
receivable, accounts payable, loans payable and capital asset obligations that
are carried at cost which approximates fair value.
 
 Recent Accounting Pronouncements
 
  In June 1997 the Financial Accounting Standards Board (FASB) issued Reporting
Comprehensive Income (SFAS No. 130), which establishes standards for reporting
and display of comprehensive income and its components in the financial
statements. SFAS No. 130 is effective for fiscal years beginning after December
15, 1997. Reclassification of financial statements for earlier periods provided
for comparative purposes is required. SFAS No. 130 offers alternatives for
presentation of disclosures required by the standard. The adoption of SFAS No.
130 had no impact on the Company's results of operations, financial position or
cash flows.
 
  In the June 1997 FASB issued Disclosures about Segments of an Enterprise and
Related Information (SFAS No. 131), which establishes standards for reporting
information about operating segments in annual financial statements. It also
establishes standards for related disclosures about products and services,
geographic areas, and major customers. SFAS No. 131 is effective for fiscal
years beginning after December 15, 1997. The adoption of SFAS No. 131 will not
have an impact on the Company's results of operations, financial position or
cash flows.
 
  In February l998 FASB issued SFAS No. 132, Employers' Disclosures about
Pension and Other Postretirement Benefits (SFAS No. 132), which revises
employers' disclosures about pension and other postretirement benefit plans.
SFAS No. 132 does not change the measurement or recognition of those plans.
SFAS No. 132 is effective for fiscal years beginning after December 15, 1997.

adoption of SFAS No. 132 will not have an impact on the Company's results of
operations, financial position or cash flows.
 
  In March l998 the American Institute of Certified Public Accounts (AICPA)
issued Statement of Position 98-1, Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use (SOP 98-1). SOP 98-1 is effective for
financial statements for years beginning after December 15, 1998. SOP 98-1
provides guidance over accounting for computer software developed or obtained
for internal use including the requirement to capitalize specified costs and
amortization of such costs. The Company does not expect the adoption of this
standard to have a material effect on the Company's capitalization policy.
 
  In April 1998 the AICPA issued Statement of Position 98-5, Reporting on the
Costs of Start-Up Activities (SOP 98-5). SOP 98-5, which is effective for
fiscal years beginning after December 15, 1998, provides guidance on the
financial reporting of start-up costs and organization costs. It requires costs
of start up activities and organization costs to be expensed as incurred. As
the Company has expensed these costs historically, the adoption of this
standard is not expected to have a significant impact on the Company's results
of operations, financial position, or cash flows.

      UNAUDITED PRO FORMA FINANCIAL INFORMATION BASIS OF PRESENTATION     
 
  The following unaudited pro forma data is filed herewith: Unaudited condensed
combined pro forma statements of operations for the year ended December 31,
1997 and nine months ended September 30, 1998.
 
  The unaudited condensed combined pro forma statements of operations reflect
the acquisitions of Boulder Interactive Technology Services Company (BITC) as
if it occurred on January 1, 1997 and Informatrix as if it had occurred on its
inception of October 15, 1997. Since the pro forma financial statements which
follow are based upon the financial condition and operating results of the BITC
and Informatrix during periods when they were not under the control or
management of VerticalNet, Inc. (VerticalNet), the information presented may
not be indicative of the results which would have actually been obtained had
the acquisitions been completed as of January 1, 1997 nor are they indicative
of future financial or operating results. The unaudited pro forma financial
information does not give effect to any synergies that may occur due to the
integration of VerticalNet, BITC and Informatrix. The condensed combined pro
forma financial statements should be read in conjunction with the historical
audited financial statements of VerticalNet and the notes thereto, as well as
the audited historical financial statements of BITC and Informatrix and the
notes thereto included elsewhere in this prospectus. The acquisitions have been
accounted for by the purchase method of accounting. A pro forma balance sheet
as of September 30, 1998 has not been presented herein since both acquisitions
were completed in September of 1998 and have been reflected in VerticalNet's
consolidated balance sheet as of September 30, 1998 appearing elsewhere herein.

           NOTES TO PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
1. Basis of Presentation
   
  The unaudited pro forma condensed combined statements of operations for the
nine months ended September 30, 1998 and the year ended December 31, 1997 give
effect to the acquisition of BITC as if it had occurred on January 1, 1997 and
Informatrix as if has occurred on its inception of October 15, 1997. The
statement of operations for BITC for the nine months ended September 30, 1998
includes their operations for January 1, 1998 through September 1, 1998, the
date of acquisition by the Company.     
 
  The effects of the acquisitions have been presented using the purchase method
of accounting and accordingly, the purchase price was allocated to the assets
acquired and liabilities assumed based upon management's best preliminary
estimate of their fair value. The preliminary allocation of the purchase price
will be subject to further adjustments, which are not anticipated to be
material, as VerticalNet finalizes its allocation of its purchase price in
accordance with generally accepted accounting principles. The pro forma
adjustments related to the purchase price allocation of the acquisition
represent management's best estimate of the effects of the acquisition.
 
2. Pro forma statement of operations adjustments consist of:
 
  The pro forma statement of operations adjustments for the year ended December

vertical trade community.
 
  (b) General and administrative expense has been adjusted to reflect the
amortization of goodwill associated with the acquisitions which has an
estimated useful life of 36 months.

interest expense incurred by Informatrix on indebtedness to VerticalNet.
 
  The pro forma statement of operations adjustments for the nine months ended
September 30, 1998 consist of:

and the inability of the Company to currently use the benefits of the net
operating loss carryforward.

Item 14. Indemnification of Directors and Officers.
 
  The Company's Amended and Restated Articles of Incorporation provide that
pursuant to and to the extent permitted by Pennsylvania law, the Company's
directors shall not be personally liable for monetary damages for breach of any
duty owed to the Company and its shareholders. This provision does not
eliminate the duty of care, and, in appropriate circumstances, equitable
remedies such as an injunction or other forms of non-monetary relief would
remain available under Pennsylvania law. In addition, each director will
continue to be subject to liability for breach of the director's duty of
loyalty to the Company, for acts or omissions not in good faith or involving
knowing violations of law, or for actions resulting in improper personal
benefit to the director, the provision also does not affect a director's
responsibilities under any other law, such as federal securities laws or state
or federal environmental laws. The Company's Amended and Restated Bylaws
provide that the Company shall indemnify its officers and directors to the
fullest extent permitted by Pennsylvania law, including some instances in which
indemnification is otherwise discretionary under Pennsylvania law. Pennsylvania
law permits the Registrant to provide similar indemnification to employees and
agents who are not directors or officers. The determination of whether an
individual meets the applicable standard of conduct may be made by the
disinterested directors, independent legal counsel or the shareholders.
Pennsylvania law also permits indemnification in connection with a proceeding
brought by or in the right of the Registrant to procure a judgment in its
favor. Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers, or persons controlling the
Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the Commission such indemnification is against
public policy as expressed in that Act and is therefore unenforceable.
 
  In general, any officer or director of the Company shall be indemnified by
the Company against expenses including attorneys' fees, judgments, fines and
settlements actually and reasonably incurred by that person in connection with
a legal proceeding as a result of such relationship, whether or not
 
                                      II-1
<PAGE>
 
the indemnified liability arises from an action by or in the right of the
Company, if the officer or director acted in good faith, and in the manner
believed to be in or not opposed to the Company's best interest, and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe the conduct was unlawful. Such indemnity is limited to the extent that
(i) such person is not otherwise indemnified and (ii) such indemnifications not
prohibited by Pennsylvania law or any other applicable law.
   
  Any indemnification under the previous paragraph (unless ordered by a court)
shall be made by the Company only as authorized in the specific case upon the
determination that indemnification of the director or officer is proper in the
circumstances because that person has met the applicable standard of conduct
set forth above. Such determination shall be made (i) by the board of directors
by a majority vote of a quorum of disinterested directors who are not parties
to such action or (ii) if such quorum is not obtainable or, even if obtainable
a quorum of disinterested directors so directs, by independent legal counsel in
a written opinion. To the extent that a director or officer of the Company
shall be successful in prosecuting an indemnity claim, the reasonable expenses
of any such person and the fees and expenses of any special legal counsel
engaged to determine the possibility of indemnification shall be borne by the
Company.     
 
  Expenses incurred by a director or officer of the Company in defending a
civil or criminal action, suit or proceeding shall be paid by the Company in
advance of the final disposition of such action, suit or proceeding upon
receipt of an undertaking by or on behalf of such director or officer to repay
such amount if it shall ultimately be determined that person is not entitled to
be indemnified by the Company as authorized by our Bylaws.
 
  The indemnification and advancement of expenses provided by, or granted
pursuant to Article   of our Bylaws is not deemed exclusive of any other rights
to which those seeking indemnification or advancement of expenses may be
entitled, both as to action in that person's official capacity and as to action
in another capacity while holding such office.
   
  The Board of Directors has the power to authorize the Company to purchase and
maintain insurance on behalf of the Company and others to the extent that power
to do so has not been prohibited by the Pennsylvania law, create any fund to
secure any of its indemnification obligations and give other indemnification to
the extent permitted by law. The obligations of the Company to indemnify a
director or officer under our Bylaws is a contract between the Company and such
director or officer and no modification or repeal of our Bylaws shall
detrimentally affect such officer or director with regard to that person's acts
or omissions prior to such amendment or repeal.     
 
  The Company has also purchased insurance for its directors and officers for
certain losses arising from claims or charges made against them in their
capacities as directors and officers of the Company.

</TABLE>    
 
  The Company believes that the issuance of shares and grants of options
described above did not involve a public offering and were exempt from
registration under Section 4(2) of the Securities Act because such issuances
and grants were made to a limited group of persons, each of whom was believed
to have been a sophisticated investor or had a pre-existing business or
personal relationship with the Company or its management and because each such
person was purchasing for investment without a view to further distribution.
Restrictive legends were placed on stock certificates and are contained in
stock option agreements evidencing the securities described above.

Item 17. Undertakings.
   
  The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreements certificates in such
denominations and registered in such amount as required by the underwriters to
permit prompt delivery to each purchaser.     
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the 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 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.
 
                                      II-6

  (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.

     Prospectus will, when they become effective or are filed with the
     Commission, as the case may be, conform in all respects to the requirements
     of the Securities Act and the Rules and Regulations and do not and will

     and any amendment thereto) and as of the applicable filing date (as to the
     Prospectus and any amendment or supplement thereto) contain an 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

     information contained in or omitted from the Registration Statement or the
     Prospectus in reliance upon and in conformity with written information
     concerning such Underwriter furnished to the Company through the
     Representatives by or on behalf of any Underwriter specifically for
     inclusion therein.

          (c)  The Company and each of its subsidiaries (as defined in Section
     15) have been duly incorporated and are validly existing as corporations in
     good standing under the laws of their respective jurisdictions of
     incorporation, are duly qualified to do business and are in good standing
     as foreign corporations in each jurisdiction in which their respective
     ownership or lease of property or the conduct of their respective
     businesses requires such qualification, and have all power and authority
     necessary to own or hold their respective properties and to conduct the
     businesses in which they are engaged; and none of the subsidiaries of the
     Company, [(other than _____ )] is a "significant subsidiary," as such term

     authorized and issued and are fully paid and non-assessable and (except for
     directors' qualifying shares) are owned directly or indirectly by the
     Company, free and clear of all liens, encumbrances, equities or claims.

          (e)  The shares of the Stock to be issued and sold by the Company to
     the Underwriters hereunder have been duly and validly authorized and, when
     issued and delivered against payment therefor as provided herein, will be
     duly and validly issued, fully paid and non-assessable; and the Stock will
     conform to the description thereof contained in the Prospectus.

          (f)  This Agreement has been duly authorized, executed and delivered
     by the Company.

          (g)  The execution, delivery and performance of this Agreement by the
     Company and the consummation of the transactions contemplated hereby [and
     by the formation of one or more subsidiaries of the Company and the
     transfer of assets thereto described in the Prospectus under the caption
     "_____" (such actions are herein collectively called the "Reorganization")

     terms or provisions of, or constitute a default under, any indenture,

     which the Company or any of its subsidiaries is a party or by which the
     Company or any of its subsidiaries is bound or to which any of the property

     order, rule or regulation of any court or governmental agency or body
     having jurisdiction over the Company or any of its subsidiaries or any of

     other action will not have a material adverse effect on the consolidated
     financial position, stockholders' equity, results of operations, business
     or prospects of the Company and its subsidiaries (herein a "Material
     Adverse Effect"). The Reorganization has been duly authorized and approved
     by the Company and the Company's stockholders to the extent required by
     law.

          (h)  Except as described in the Prospectus, there are no contracts,
     agreements or understandings between the Company and any person granting
     such person the right to require the Company to file a registration

     issued pursuant to employee benefit plans, qualified stock option plans or
     other employee compensation plans or pursuant to outstanding options,
     rights or warrants outstanding prior to the commencement of such six-month
     period.

          (j)  Neither the Company nor any of its subsidiaries has sustained,
     since the date of the latest audited financial statements included in the

     explosion, flood or other calamity, whether or not covered by insurance, or
     from any labor dispute or court or governmental action, order or decree,
     otherwise than as set forth or contemplated in the Prospectus; and, since
     such date, there has not been any change in the capital stock or long-term
     debt of the Company or any of its subsidiaries or any material adverse
     change, or any development involving a prospective material adverse change,
     in or affecting the general affairs, management, financial position,
     stockholders' equity or results of operations of the Company and its
     subsidiaries, otherwise than as set forth or contemplated in the
     Prospectus.

          (k)  The financial statements (including the related notes and
     supporting schedules) filed as part of the Registration Statement or
     included in the Prospectus present fairly the financial condition and
     results of operations of the entities purported to be shown thereby, at the
     dates and for the periods indicated, and have been prepared in conformity
     with generally accepted accounting principles applied on a consistent basis
     throughout the periods involved.  The selected and summary financial and

     present fairly the information shown therein and have been compiled on a
     basis substantially consistent with the financial statements presented
     therein.  The pro forma financial statements and other pro forma financial
     information included in the Registration Statement and the Prospectus (i)
     present fairly, in all material respects, the information shown therein,
     (ii) have been prepared in accordance with the Rules and Regulations with
     respect to pro forma financial statements and (iii) have been properly
     compiled on the bases described therein, and the assumptions used in the
     preparation of the pro forma financial statements and other pro forma
     financial information and included in the Registration Statement and the

     to give effect to the transactions or circumstances referred to therein.

                                       7

Company; provided, that under no circumstances will the Representatives or any
Underwriter be liable to the Company or to any such person for any action taken

is further understood that any shares of such Firm Stock which are not purchased

Agreement is a further condition of the obligation of each Underwriter
hereunder.  Upon delivery, the Firm Stock shall be registered in such names and

shall set forth the aggregate number of shares of Option Stock as to which the
option is being exercised, the names in which the shares of Option Stock are to

          violation of any of the terms or provisions of, or constitute a
          default under, any indenture, mortgage, deed of trust, loan agreement
          or other agreement or instrument known to such counsel to which the

<PAGE>
 
          obtain such consent, approval authorization or order, or to effect
          such filing or registration, or such conflict, breach, violation,
          default or other action will not have a Material Adverse Effect; and

                 (xii)  Except as described in the Prospectus, to the best of
          such counsel's knowledge, there are no contracts, agreements or
          understandings between the Company and any person granting such person
          the right (other than rights which have been waived or satisfied) to
          require the Company to file a registration statement under the
          Securities Act with respect to any securities of the Company owned or
          to be owned by such person or the right (other than rights which have
          been waived or satisfied) to require the Company to include such
          securities in the securities registered pursuant to the Registration
          Statement or in any securities being registered pursuant to any other
          registration statement filed by the Company under the Securities Act.

     In rendering such opinion, such counsel may state that its opinion is
     limited to matters governed by the Federal laws of the United States of
     America, the laws of the Commonwealth of Pennsylvania and the General
     Corporation Law of the State of Delaware.  Such counsel shall also have
     furnished to the Representatives a written statement, addressed to the
     Underwriters and dated such Delivery Date, in form and substance
     satisfactory to the Representatives, to the effect that (x) such counsel
     has acted as regular outside counsel to the Company (although the Company
     is also represented by other outside counsel with respect to intellectual
     property and other matters), has acted as counsel to the Company in
     connection with previous financing transactions and has acted as counsel to
     the Company in connection with the preparation of the Registration
     Statement, and (y) based on the foregoing, no facts have come to the
     attention of such counsel which lead it to believe that the Registration
     Statement, as of the Effective Date, contained any untrue statement of a
     material fact or omitted to state a material fact required to be stated
     therein or necessary in order to make the statements therein not
     misleading, or that the Prospectus contains any untrue statement of a
     material fact or omits to state a material fact required to be stated
     therein or necessary in order to make the statements therein, in light of
     the circumstances under which they were made, not misleading.  The
     foregoing opinion and statement may be qualified by a statement to the
     effect that such counsel does not assume any responsibility for the
     accuracy, completeness or fairness of the statements contained in the
     Registration Statement or the Prospectus or express any view as to the
     financial statements and schedules and other financial data contained
     therein.

          (e)  The Representatives shall have received from Chadbourne & Parke
     LLP, counsel for the Underwriters, such opinion or opinions, dated such
     Delivery Date, with respect to the Registration Statement and the
     Prospectus and other related matters as the Representatives may reasonably
     require, and the Company shall have furnished to such counsel such
     documents as they reasonably request for the purpose of enabling them to
     pass upon such matters.

                                       15

          (f)  At the time of execution of this Agreement, the Representatives
     shall have received from KPMG Peat Marwick a letter, in form and substance
     satisfactory to the Representatives, addressed to the Underwriters and
     dated the date hereof (i) confirming that they are independent public
     accountants within the meaning of the Securities Act and are in compliance
     with the applicable requirements relating to the qualification of
     accountants under Rule 2-01 of Regulation S-X of the Commission, (ii)
     stating, as of the date hereof (or, with respect to matters involving
     changes or developments since the respective dates as of which specified
     financial information is given in the Prospectus, as of a date not more
     than five days prior to the date hereof), the conclusions and findings of
     such firm with respect to the financial information and other matters
     ordinarily covered by accountants' "comfort letters" to underwriters in
     connection with registered public offerings.

          (g)  With respect to the letter of KPMG Peat Marwick referred to in
     the preceding paragraph and delivered to the Representatives concurrently
     with the execution of this Agreement (the "initial letter"), the Company
     shall have furnished to the Representatives a letter (the "bring-down
     letter") of such accountants, addressed to the Underwriters and dated such
     Delivery Date (i) confirming that they are independent public accountants
     within the meaning of the Securities Act and are in compliance with the
     applicable requirements relating to the qualification of accountants under
     Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as of the date
     of the bring-down letter (or, with respect to matters involving changes or
     developments since the respective dates as of which specified financial
     information is given in the Prospectus, as of a date not more than five
     days prior to the date of the bring-down letter), the conclusions and
     findings of such firm with respect to the financial information and other
     matters covered by the initial letter and (iii) confirming in all material
     respects the conclusions and findings set forth in the initial letter.

          (h)  The Company shall have furnished to the Representatives a
     certificate, dated such Delivery Date, of its Chairman of the Board, its
     President or a Vice President and its chief financial officer stating that:

                  (i)   The representations, warranties and agreements of the
          Company in Section 1 are true and correct as of such Delivery Date;
          the Company has complied with all its agreements contained herein; and
          the conditions set forth in Sections 8(a) and 8j(m) have been
          fulfilled; and

                  (ii)  They have carefully examined the Registration Statement
          and the Prospectus and, in their opinion (A) as of the Effective Date,
          the Registration Statement and Prospectus did not include any untrue
          statement of a material fact and did not omit to state a material fact
          required to be stated therein or necessary to make the statements
          therein not misleading, and (B) since the Effective Date no event has
          occurred which should have been set forth in a supplement or amendment
          to the Registration Statement or the Prospectus.

          (i) (i) Neither the Company nor any of its subsidiaries shall have
     sustained since the date of the latest audited financial statements
     included in the Prospectus any loss or 

                                       16
<PAGE>
 
     interference with its business from fire, explosion, flood or other
     calamity, whether or not covered by insurance, or from any labor dispute or
     court or governmental action, order or decree, otherwise than as set forth
     or contemplated in the Prospectus or (ii) since such date there shall not
     have been any change in the capital stock or long-term debt of the Company
     or any of its subsidiaries or any change, or any development involving a
     prospective change, in or affecting the general affairs, management,
     financial position, stockholders' equity or results of operations of the
     Company and its subsidiaries, otherwise than as set forth or contemplated
     in the Prospectus, the effect of which, in any such case described in
     clause (i) or (ii), is, in the judgment of the Representatives, so material
     and adverse as to make it impracticable or inadvisable to proceed with the
     public offering or the delivery of the Stock being delivered on such
     Delivery Date on the terms and in the manner contemplated in the
     Prospectus.

          (j)  Subsequent to the execution and delivery of this Agreement there
     shall not have occurred any of the following: (i) trading in securities
     generally on the New York Stock Exchange or the American Stock Exchange or
     in the over-the-counter market, or trading in any securities of the Company
     on any exchange or in the over-the-counter market, shall have been
     suspended or minimum prices shall have been established on any such
     exchange or such market by the Commission, by such exchange or by any other
     regulatory body or governmental authority having jurisdiction, (ii) a
     banking moratorium shall have been declared by Federal or state
     authorities, (iii) the United States shall have become engaged in
     hostilities, there shall have been an escalation in hostilities involving
     the United States or there shall have been a declaration of a national
     emergency or war by the United States or (iv) there shall have occurred
     such a material adverse change in general economic, political or financial
     conditions (or the effect of international conditions on the financial
     markets in the United States shall be such) as to make it, in the judgment
     of a majority in interest of the several Underwriters, impracticable or
     inadvisable to proceed with the public offering or delivery of the Stock
     being delivered on such Delivery Date on the terms and in the manner
     contemplated in the Prospectus.

          (k)  The Nasdaq National Market shall have approved the Stock for
     inclusion, subject only to official notice of issuance and evidence of
     satisfactory distribution.

          (l)  You shall have been furnished with such additional documents and
     certificates as you or counsel for the Underwriters may reasonably request
     related to this Agreement and the transactions contemplated hereby.

          All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance  reasonably
satisfactory to counsel for the Underwriters.

          8.  Indemnification and Contribution.

          (a)  The Company shall 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, from and against any loss, claim,
damage or liability, joint or several, or any action 

                                       17
<PAGE>
 
in respect thereof (including, but not limited to, any loss, claim, damage,
liability or action relating to purchases and sales of Stock), to which that
Underwriter, officer, employee or controlling person may become subject, under
the Securities Act or otherwise, insofar as such loss, claim, damage, liability
or action arises out of, or is based upon, (i) any untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus or in any amendment or supplement
thereto, (ii) the omission or alleged omission to state in any Preliminary
Prospectus, the Registration Statement or the Prospectus, or in any amendment or
supplement thereto, or in any Blue Sky Application any material fact required to
be stated therein or necessary to make the statements therein not misleading or
(iii) 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 Stock 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
matters covered by clause (i) or (ii) above (provided that the Company shall not
be liable under this clause (iii) to the extent that it is determined in a final
judgment by a court of competent jurisdiction 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 gross
negligence or willful misconduct), and shall reimburse each Underwriter and each
such officer, employee or controlling person promptly upon demand for any legal
or other expenses reasonably incurred by that Underwriter, officer, employee or
controlling person in connection with investigating or defending or preparing to
defend against any such loss, claim, damage, liability or action as such
expenses are incurred; provided, however, that the Company shall not be liable
in any such case to the extent that any such loss, claim, damage, liability or
action arises out of, or is based upon, any untrue statement or alleged untrue
statement or omission or alleged omission made in any Preliminary Prospectus,
the Registration Statement or the Prospectus, or in any such amendment or
supplement, in reliance upon and in conformity with written information
concerning such Underwriter furnished to the Company through the Representatives
by or on behalf of any Underwriter specifically for inclusion therein which
information consists solely of the information specified in Section 7(e). The
foregoing indemnity agreement is in addition to any liability which the Company
may otherwise have to any Underwriter or to any officer, employee or controlling
person of that Underwriter.

          (b)  Each Underwriter, severally and not jointly, shall indemnify and
hold harmless the Company, its officers and employees, each of its directors,
and each person, if any, who controls the Company within the meaning of the
Securities Act, from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof, to which the Company or any such
director, officer or controlling person may become subject, under the Securities
Act or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon, (i) any untrue statement or alleged untrue
statement of a material fact contained (A) in any Preliminary Prospectus, the
Registration Statement or the Prospectus or in any amendment or supplement
thereto, or (B) in any Blue Sky Application or (ii) the omission or alleged
omission to state in any Preliminary Prospectus, the Registration Statement or
the Prospectus, or in any amendment or supplement thereto, or in any Blue Sky
Application any material fact required to be stated therein or necessary to make
the statements therein not misleading, but in each case only to the extent that
the untrue statement or alleged untrue statement or omission or alleged omission
was made in reliance upon and in conformity with written information concerning
such Underwriter furnished to the Company through the Representatives by or on
behalf of that Underwriter specifically for 

                                       18
<PAGE>
 
inclusion therein, and shall reimburse the Company and any such director,
officer or controlling person for any legal or other expenses reasonably
incurred by the Company or any such director, officer or controlling person in
connection with investigating or defending or preparing to defend against any
such loss, claim, damage, liability or action as such expenses are incurred. The
foregoing indemnity agreement is in addition to any liability which any
Underwriter may otherwise have to the Company or any such director, officer,
employee or controlling person.

          (c)  Promptly after receipt by an indemnified party under this Section
8 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 8, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 8 except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified party otherwise than under this Section 8.
If any such claim or action shall be brought against an indemnified party, and
it shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof
with counsel reasonably satisfactory to the indemnified party.  After notice
from the indemnifying party to the indemnified party of its election to assume
the defense of such claim or action, the indemnifying party shall not be liable
to the indemnified party under this Section 8 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
the Representatives shall have the right to employ counsel to represent jointly
the Representatives and those other Underwriters and their respective officers,
employees and controlling persons who may be subject to liability arising out of
any claim in respect of which indemnity may be sought by the Underwriters
against the Company under this Section 8 if, in the reasonable judgment of the
Representatives, it is advisable for the Representatives and those Underwriters,
officers, employees and controlling persons to be jointly represented by
separate counsel, and in that event the fees and expenses of such separate
counsel shall be paid by the Company.  No indemnifying party shall (i) without
the prior written consent of the indemnified parties (which consent shall not be
unreasonably withheld), settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding, or (ii) be liable for any
settlement of any such action effected without its written consent (which
consent shall not be unreasonably withheld), but if settled with the consent of
the indemnifying party or if there be a final judgment of the plaintiff in any
such action, the indemnifying party agrees to indemnify and hold harmless any
indemnified party from and against any loss or liability by reason of such
settlement or judgment.

          (d)  If the indemnification provided for in this Section 8 shall for
any reason be unavailable to or insufficient to hold harmless an indemnified
party under Section 8(a) or 8(b) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, 

                                       19
<PAGE>
 
then each 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 loss, claim, damage or liability, or action in respect thereof,
(i) in such proportion as shall be 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 Stock or (ii) if the allocation provided by clause (i) above
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also
the relative fault of the Company on the one hand and the Underwriters on the
other with respect to the statements or omissions which resulted in such loss,
claim, damage or liability, or action 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 with respect to such offering
shall be deemed to be in the same proportion as the total net proceeds from the
offering of the Stock purchased under this Agreement (before deducting expenses)
received by the Company, on the one hand, and the total underwriting discounts
and commissions received by the Underwriters with respect to the shares of the
Stock purchased under this Agreement, on the other hand, bear to the total gross
proceeds from the offering of the shares of the Stock under this Agreement, 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 whether the untrue or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact relates to information supplied by the Company or the
Underwriters, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Underwriters agree that it would not be just and equitable
if contributions pursuant to this Section 8(d) were to be determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take into account
the equitable considerations referred to herein. The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability, or
action in respect thereof, referred to above in this Section shall be deemed to
include, for purposes of this Section 8(d), 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
Section 8(d), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Stock underwritten by
it and distributed to the public was offered to the public exceeds the amount of
any damages which such Underwriter has otherwise paid or become liable to pay by
reason of any untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 10(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. The
Underwriters' obligations to contribute as provided in this Section 8(d) are
several in proportion to their respective underwriting obligations and not
joint.

          (e)  The Underwriters severally confirm and the Company acknowledges
that the statements with respect to the public offering of the Stock by the
Underwriters set forth on the cover page of, the legend concerning over-
allotments on the inside front cover page of and the concession and reallowance
figures appearing under the caption "Underwriting" in, the Prospectus are
correct and constitute the only information concerning such Underwriters
furnished in writing to the Company by or on behalf of the Underwriters
specifically for inclusion in the Registration Statement and the Prospectus.

          9.  Defaulting Underwriters.

          If, on either Delivery Date, any Underwriter defaults in the
performance of its obligations under this Agreement, the remaining non-
defaulting Underwriters shall be obligated to purchase the Stock which the
defaulting Underwriter agreed but failed to purchase on such Delivery Date in
the respective proportions which the number of shares of the Firm Stock set
opposite the name of each remaining non-defaulting Underwriter in Schedule 1
hereto bears to the total number of shares of the Firm Stock set opposite the
names of all the remaining non-defaulting Underwriters in Schedule 1 hereto;
provided, however, that the remaining non-defaulting Underwriters shall not be
obligated to purchase any of the Stock on such Delivery Date if the total number
of shares of the Stock which the defaulting Underwriter or Underwriters agreed
but failed to purchase on such date exceeds 9.09% of the total number of shares
of the Stock to be purchased on such Delivery Date, and any remaining non-
defaulting Underwriter shall not be obligated to purchase more than 110% of the
number of shares of the Stock which it agreed to purchase on such Delivery Date
pursuant to the terms of Section 2.  If the foregoing maximums are exceeded, the
remaining non-defaulting Underwriters, or those other underwriters satisfactory
to the Representatives who so agree, shall have the right, but shall not be
obligated, to purchase, in such proportion as may be agreed upon among them, all
the Stock to be purchased on such Delivery Date.  If the remaining Underwriters
or other underwriters satisfactory to the Representatives do not elect to
purchase the shares which the defaulting Underwriter or Underwriters agreed but
failed to purchase on such Delivery Date, this Agreement (or, with respect to
the Second Delivery Date, the obligation of the Underwriters to purchase, and of
the Company to sell, the Option Stock) shall terminate without liability on the
part of any non-defaulting Underwriter or the Company, except that the Company
will continue to be liable for the payment of expenses to the extent set forth
in Sections 6 and 11.  As used in this Agreement, the term "Underwriter"
includes, for all purposes of this Agreement unless the context requires
otherwise, any party not listed in Schedule 1 hereto who, pursuant to this
Section 9, purchases Firm Stock which a defaulting Underwriter agreed but failed
to purchase.

          Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company for damages caused by its default.  If
other underwriters are obligated or agree to purchase the Stock of a defaulting
or withdrawing Underwriter, either the Representatives or the Company may
postpone the Delivery Date for up to seven full business days in order to effect
any changes that in the opinion of counsel for the Company or counsel for the
Underwriters may be necessary in the Registration Statement, the Prospectus or
in any other document or arrangement.

          10.  Termination.  The obligations of the Underwriters hereunder may
be terminated by the Representatives by notice given to and received by the
Company prior to delivery of and payment for the Firm Stock if, prior to that
time, any of the events described in Section 7(i) or 7(j), shall have occurred
or if the Underwriters shall decline to purchase the Stock for any reason
permitted under this Agreement.

          11.  Reimbursement of Underwriters' Expenses.  If (a) the Company
shall fail to tender the Stock for delivery to the Underwriters by reason of any
failure, refusal or inability on the part of the Company to perform any
agreement on its part to be performed, or because any other 

                                       21
<PAGE>
 
condition of the Underwriters' obligations hereunder required to be fulfilled by
the Company is not fulfilled, the Company will reimburse the Underwriters for
all reasonable out-of-pocket expenses (including fees and disbursements of
counsel) incurred by the Underwriters in connection with this Agreement and the
proposed purchase of the Stock, and upon demand the Company shall pay the full
amount thereof to the Representative(s). If this Agreement is terminated
pursuant to Section 9 by reason of the default of one or more Underwriters, the
Company shall be obligated to reimburse any defaulting Underwriter on account of
those expenses.

          12.  Notices, etc.  All statements, requests, notices and agreements
hereunder shall be in writing, and:

          (a)  if to the Underwriters, shall be delivered or sent by mail, telex

shall be delivered or sent by mail, telex or facsimile transmission to such

Representatives upon request. Any such statements, requests, notices or
agreements shall take effect at the time of receipt thereof. The Company shall
be entitled to act and rely upon any request, consent, notice or agreement given
or made on behalf of the Underwriters by Lehman Brothers Inc. on behalf of the
Representatives.

          13.  Persons Entitled to Benefit of Agreement. This Agreement shall

intended or shall be construed to give any person, other than the persons
referred to in this Section 13, any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision contained herein.

          14.  Survival.  The respective indemnities, representations,
warranties and agreements of the Company and the Underwriters contained in this

behalf on them, respectively, pursuant to this Agreement, shall survive the
delivery of and payment for the Stock and shall remain in full force and effect,
regardless of any investigation made by or on behalf of any of them or any
person controlling any of them.

purposes of this Agreement, (a) "business day" means each Monday, Tuesday,
Wednesday, Thursday or Friday which is not a day on which banking institutions
in New York are generally authorized or obligated by law or executive order to

and Regulations.

          16.  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE
PERFORMED IN THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICT OF LAW
PROVISIONS.

          17.  Counterparts.  This Agreement may be executed in one or more
counterparts and, if executed in more than one counterpart, the executed
counterparts shall each be deemed to be an original but all such counterparts
shall together constitute one and the same instrument.

                               VERTICALNET, INC.

               AMENDED AND RESTATED 1996 EQUITY COMPENSATION PLAN
               --------------------------------------------------


     The purpose of the VerticalNet, Inc. Amended and Restated 1996 Equity
Compensation Plan (the "Plan") is to provide (i) designated employees of
VerticalNet, Inc. (the "Company") and its subsidiaries, (ii) certain consultants
and advisors who perform services for the Company or its subsidiaries and (iii)
non-employee members of the Board of Directors of the Company (the "Board") with
the opportunity to receive grants of incentive stock options, nonqualified stock
options and restricted stock.  The Company believes that the Plan will encourage
the participants to contribute materially to the growth of the Company, thereby
benefitting the Company's shareholders, and will align the economic interests of
the participants with those of the shareholders.

     1.  Administration
         --------------

     (a) Authority.  The Plan shall be administered and interpreted by the
         ---------                                                        
Board.  If the Company has an initial public offering ("Public Offering") of its
stock as described in Section 19(b), the Plan shall thereafter be administrated
by a committee, which shall consist of two or more persons appointed by the
Board, all of whom shall be "outside directors" as defined under section 162(m)
of the Internal Revenue Code of 1986, as amended (the "Code") and related
Treasury regulations, and "non-employee directors" as defined under Rule 16b-3
under the Securities Exchange Act of 1934, as amended (the "Exchange Act").  The
Board may ratify or approve any grants made to participants.  References in the
Plan to the "Board", as they relate to Plan administration, shall be deemed to
refer to the committee if a committee is appointed to administer the Plan.

     (b) Board Authority.  The Board shall have the sole authority to (i)
         ---------------                                                 
determine the individuals to whom grants shall be made under the Plan, (ii)
determine the type, size and terms of the grants to be made to each such
individual, (iii) determine the time when the grants will be made and the
duration of any applicable exercise or restriction period, including the
criteria for exercisability and the acceleration of exercisability and (iv) deal
with any other matters arising under the Plan.  The Board may require that a
grantee execute a shareholder's agreement, with such terms as the Board deems
appropriate, with respect to any Company stock distributed pursuant to this
Plan.

     (c) Board Determinations.  The Board shall have full power and authority to
         -------------------                                                    
administer and interpret the Plan, to make factual determinations and to adopt
or amend such rules, regulations, agreements and instruments for implementing
the Plan and for the conduct of its business as it deems necessary or advisable,
in its sole discretion.  The Board's interpretations of the Plan and all
determinations made by the Board pursuant to the powers vested in it hereunder
shall be conclusive and binding on all persons having any interest in the Plan
or in any 
<PAGE>
 
awards granted hereunder.  All powers of the Board shall be executed in its sole
discretion, in the best interest of the Company, not as a fiduciary, and in
keeping with the objectives of the Plan and need not be uniform as to similarly
situated individuals.

     2.   Grants
          ------

     Awards under the Plan may consist of grants of incentive stock options as
described in Section 5 ("Incentive Stock Options"), nonqualified stock options
as described in Section 5 ("Nonqualified Stock Options") (Incentive Stock
Options and Nonqualified Stock Options are collectively referred to as
"Options") or restricted stock as described in Section 6 (Restricted Stock")
(hereinafter collectively referred to as "Grants").  All Grants shall be subject
to the terms and conditions set forth herein and to such other terms and
conditions consistent with this Plan as the Board deems appropriate and as are
specified in writing by the Board to the individual in a grant instrument (the
"Grant Instrument") or an amendment to the Grant Instrument.  The Board shall
approve the form and provisions of each Grant Instrument.  Grants under a
particular Section of the Plan need not be uniform as among the grantees.

     3.  Shares Subject to the Plan
         --------------------------

     (a) Shares Authorized.  Subject to the adjustment specified below, the
         -----------------                                                 
aggregate number of shares of common stock of the Company ("Company Stock") that
may be issued or transferred under the Plan is 3,600,000 shares, and, after a
Public Offering,  the maximum aggregate number of shares of Company Stock that
shall be subject to Grants made under the Plan to any individual during any
calendar year shall be 500,000 shares.  The shares may be authorized but
unissued shares of Company Stock or reacquired shares of Company Stock,
including shares purchased by the Company on the open market for purposes of the
Plan.  If and to the extent Options granted under the Plan terminate, expire, or
are canceled, forfeited, exchanged or surrendered without having been exercised
or if any shares of Restricted Stock are forfeited, the shares subject to such
Grants shall again be available for purposes of the Plan.

     (b) Adjustments.  If there is any change in the number or kind of shares of
         -----------                                                            
Company Stock outstanding (i) by reason of a stock dividend, spinoff,
recapitalization, stock split, or combination or exchange of shares, (ii) by
reason of a merger, reorganization or consolidation in which the Company is the
surviving corporation, (iii) by reason of a reclassification or change in par
value, or (iv) by reason of any other extraordinary or unusual event affecting
the outstanding Company Stock as a class without the Company's receipt of
consideration, or if the value of outstanding shares of Company Stock is
substantially reduced as a result of a spinoff or the Company's payment of an
extraordinary dividend or distribution, the maximum number of shares of Company
Stock available for Grants, the maximum number of shares of Company Stock that
any individual participating in the Plan may be granted in any year, the number
of shares covered by outstanding Grants, the kind of shares issued under the
Plan, and the price per share or the applicable market value of such Grants may
be appropriately adjusted by the Board to reflect any increase or decrease in
the number of, or change in the kind or value of, issued shares of 
<PAGE>
 
Company Stock to preclude, to the extent practicable, the enlargement or
dilution of rights and benefits under such Grants; provided, however, that any
fractional shares resulting from such adjustment shall be eliminated. Any
adjustments determined by the Board shall be final, binding and conclusive.

     4.  Eligibility for Participation
         -----------------------------

     (a) Eligible Persons.  All employees of the Company and its subsidiaries
         ----------------                                                    
("Employees"), including Employees who are officers or members of the Board, and
members of the Board who are not Employees ("Non-Employee Directors") shall be
eligible to participate in the Plan. Consultants and advisors who perform
services to the Company or any of its subsidiaries ("Key Advisors") shall be
eligible to participate in the Plan if the Key Advisors render bona fide
services and such services are not in connection with the offer or sale of
securities in a capital-raising transaction.

     (b) Selection of Grantees.  The Board shall select the Employees, Non-
         ---------------------                                            
Employee Directors and Key Advisors to receive Grants and shall determine the
number of shares of Company Stock subject to a particular Grant in such manner
as the Board determines. Employees, Key Advisors and Non-Employee Directors who
receive Grants under this Plan shall hereinafter be referred to as "Grantees".

     5.  Granting of Options
         -------------------

     (a) Number of Shares.  The Board shall determine the number of shares of
         ----------------                                                    
Company Stock that will be subject to each Grant of Options to Employees, Non-
Employee Directors and Key Advisors.

     (b) Type of Option and Price.
         ------------------------ 

         (i)  The Board may grant Incentive Stock Options that are intended to
qualify as "incentive stock options" within the meaning of section 422 of the
Code or Nonqualified Stock Options that are not intended so to qualify or any
combination of Incentive Stock Options and Nonqualified Stock Options, all in
accordance with the terms and conditions set forth herein. Incentive Stock
Options may be granted only to Employees.  Nonqualified Stock Options may be
granted to Employees, Non-Employee Directors and Key Advisors.

         (ii) The purchase price (the "Exercise Price") of Company Stock
subject to an Option shall be determined by the Board and may be equal to,
greater than, or less than the Fair Market Value (as defined below) of a share
of Company Stock on the date the Option is granted; provided, however, that (x)
the Exercise Price of an Incentive Stock Option shall be equal to, or greater
than, the Fair Market Value of a share of Company Stock on the date the
Incentive Stock Option is granted and (y) an Incentive Stock Option may not be
granted to an Employee who, at the time of grant, owns stock possessing more
than 10 percent of the total combined voting 
<PAGE>
 
power of all classes of stock of the Company or any parent or subsidiary of the
Company, unless the Exercise Price per share is not less than 110% of the Fair
Market Value of Company Stock on the date of grant.

         (iii)  If the Company Stock is publicly traded, then the Fair Market
Value per share shall be determined as follows: (x) if the principal trading
market for the Company Stock is a national securities exchange or the Nasdaq
National Market, the last reported sale price thereof on the relevant date or
(if there were no trades on that date) the latest preceding date upon which a
sale was reported, or (y) if the Company Stock is not principally traded on such
exchange or market, the mean between the last reported "bid" and "asked" prices
of Company Stock on the relevant date, as reported on Nasdaq or, if not so
reported, as reported by the National Daily Quotation Bureau, Inc. or as
reported in a customary financial reporting service, as applicable and as the
Board determines.  If the Company Stock is not publicly traded or, if publicly
traded, is not subject to reported transactions or "bid" or "asked" quotations
as set forth above, the Fair Market Value per share shall be as determined by
the Board.

     (c) Option Term.  The Board shall determine the term of each Option.  The
         -----------                                                          
term of any Option shall not exceed ten years from the date of grant.  However,
an Incentive Stock Option that is granted to an Employee who, at the time of
grant, owns stock possessing more than 10 percent of the total combined voting
power of all classes of stock of the Company, or any parent or subsidiary of the
Company, may not have a term that exceeds five years from the date of grant.

     (d) Exercisability of Options.  Options shall become exercisable in
         -------------------------                                      
accordance with such terms and conditions, consistent with the Plan, as may be
determined by the Board and specified in the Grant Instrument or an amendment to
the Grant Instrument.  The Board may accelerate the exercisability of any or all
outstanding Options at any time for any reason.

     (e) Termination of Employment, Disability or Death.
         ---------------------------------------------- 

         (i)  Except as provided below, an Option may only be exercised while
the Grantee is employed by the Company as an Employee, Key Advisor or member of
the Board.  In the event that a Grantee ceases to be employed by the Company for
any reason other than a "disability", death, or "termination for cause", any
Option which is otherwise exercisable by the Grantee shall terminate unless
exercised within 90 days after the date on which the Grantee ceases to be
employed by the Company (or within such other period of time as may be specified
by the Board), but in any event no later than the date of expiration of the
Option term.  Any of the Grantee's Options that are not otherwise exercisable as
of the date on which the Grantee ceases to be employed by the Company shall
terminate as of such date.

         (ii) In the event the Grantee ceases to be employed by the Company on
account of a "termination for cause" by the Company, any Option held by the
Grantee shall terminate as of the date the Grantee ceases to be employed by the
Company.
<PAGE>
 
         (iii) In the event the Grantee ceases to be employed by the Company
because the Grantee is "disabled", any Option which is otherwise exercisable by
the Grantee shall terminate unless exercised within one year after the date on
which the Grantee ceases to be employed by the Company (or within such other
period of time as may be specified by the Board), but in any event no later than
the date of expiration of the Option term.  Any of the Grantee's Options which
are not otherwise exercisable as of the date on which the Grantee ceases to be
employed by the Company shall terminate as of such date.

         (iv)  If the Grantee dies while employed by the Company or within 90
days after the date on which the Grantee ceases to be employed on account of a
termination of employment specified in Section 5(e)(i) above (or within such
other period of time as may be specified by the Board), any Option that is
otherwise exercisable by the Grantee shall terminate unless exercised within one
year after the date on which the Grantee ceases to be employed by the Company
(or within such other period of time as may be specified by the Board), but in
any event no later than the date of expiration of the Option term.  Any of the
Grantee's Options that are not otherwise exercisable as of the date on which the
Grantee ceases to be employed by the Company shall terminate as of such date.

         (v)   For purposes of this Section 5(e) and Section 6:

               (A) The term "Company" shall mean the Company and its parent and
     subsidiary corporations.

               (B) "Employed by the Company" shall mean employment or service as
     an Employee, Key Advisor or member of the Board (so that, for purposes of
     exercising Options and satisfying conditions with respect to Restricted
     Stock, a Grantee shall not be considered to have terminated employment or
     service until the Grantee ceases to be an Employee, Key Advisor and member
     of the Board), unless the Board determines otherwise.

               (C) "Disability" shall mean a Grantee's becoming disabled within
     the meaning of section 22(e)(3) of the Code.

               (D) "Termination for cause" shall mean, except to the extent
     specified otherwise by the Board, a finding by the Board that the Grantee
     has breached his or her employment or service contract with the Company, or
     has been engaged in disloyalty to the Company, including, without
     limitation, fraud, embezzlement, theft, commission of a felony or proven
     dishonesty in the course of his or her employment or service, or has
     disclosed trade secrets or confidential information of the Company to
     persons not entitled to receive such information.  In the event a Grantee's
     employment is terminated for cause, in addition to the immediate
     termination of all Grants, the Grantee shall automatically forfeit all
     shares underlying any exercised portion of an Option for which the Company
<PAGE>
 
     has not yet delivered the share certificates, upon refund by the Company of
     the Exercise Price paid by the Grantee for such shares.

     (f) Exercise of Options.  A Grantee may exercise an Option that has become
         -------------------                                                   
exercisable, in whole or in part, by delivering a notice of exercise to the
Company with payment of the Exercise Price.  The Grantee shall pay the Exercise
Price for an Option as specified by the Board (x) in cash, (y) with the approval
of the Board, by delivering shares of Company Stock owned by the Grantee
(including Company Stock acquired in connection with the exercise of an Option,
subject to such restrictions as the Board deems appropriate) and having a Fair
Market Value on the date of exercise equal to the Exercise Price or (z) by such
other method as the Board may approve, including, after a Public Offering,
payment through a broker in accordance with procedures permitted by Regulation T
of the Federal Reserve Board.  Shares of Company Stock used to exercise an
Option shall have been held by the Grantee for the requisite period of time to
avoid adverse accounting consequences to the Company with respect to the Option.
The Grantee shall pay the Exercise Price and the amount of any withholding tax
due (pursuant to Section 7) at the time of exercise.

     (g) Limits on Incentive Stock Options.  Each Incentive Stock Option shall
         ---------------------------------                                    
provide that, if the aggregate Fair Market Value of the stock on the date of the
grant with respect to which Incentive Stock Options are exercisable for the
first time by a Grantee during any calendar year, under the Plan or any other
stock option plan of the Company or a parent or subsidiary, exceeds $100,000,
then the option, as to the excess, shall be treated as a Nonqualified Stock
Option.  An Incentive Stock Option shall not be granted to any person who is not
an Employee of the Company or a parent or subsidiary (within the meaning of
section 424(f) of the Code).
 
     6.   Restricted Stock Grants
          -----------------------

     The Board may issue or transfer shares of Company Stock to an Employee,
Non-Employee Director or Key Advisor under a Grant of Restricted Stock, upon
such terms as the Board deems appropriate.  The following provisions are
applicable to Restricted Stock:

     (a) General Requirements.  Shares of Company Stock issued or transferred
         --------------------                                                
pursuant to Restricted Stock Grants may be issued or transferred for
consideration or for no consideration, as determined by the Board.  The Board
may establish conditions under which restrictions on shares of Restricted Stock
shall lapse over a period of time or according to such other criteria as the
Board deems appropriate.  The period of time during which the Restricted Stock
will remain subject to restrictions will be designated in the Grant Instrument
as the "Restriction Period."

     (b) Number of Shares.  The Board shall determine the number of shares of
         ----------------                                                    
Company Stock to be issued or transferred pursuant to a Restricted Stock Grant
and the restrictions applicable to such shares.
<PAGE>
 
     (c) Requirement of Employment.  If the Grantee ceases to be employed by the
         -------------------------                                              
Company (as defined in Section 5(e)) during a period designated in the Grant
Instrument as the Restriction Period, or if other specified conditions are not
met, the Restricted Stock Grant shall terminate as to all shares covered by the
Grant as to which the restrictions have not lapsed, and those shares of Company
Stock must be immediately returned to the Company.  The Board may, however,
provide for complete or partial exceptions to this requirement as it deems
appropriate.

     (d) Restrictions on Transfer and Legend on Stock Certificate.  During the
         --------------------------------------------------------             
Restriction Period, a Grantee may not sell, assign, transfer, pledge or
otherwise dispose of the shares of Restricted Stock except to a Successor
Grantee under Section 8(a).  Each certificate for a share of Restricted Stock
shall contain a legend giving appropriate notice of the restrictions in the
Grant.  The Grantee shall be entitled to have the legend removed from the stock
certificate covering the shares subject to restrictions when all restrictions on
such shares have lapsed.  The Board may determine that the Company will not
issue certificates for shares of Restricted Stock until all restrictions on such
shares have lapsed, or that the Company will retain possession of certificates
for shares of Restricted Stock until all restrictions on such shares have
lapsed.

     (e) Right to Vote and to Receive Dividends.  Unless the Board determines
         --------------------------------------                              
otherwise, during the Restriction Period,  the Grantee shall have the right to
vote shares of Restricted Stock and to receive any dividends or other
distributions paid on such shares, subject to any restrictions deemed
appropriate by the Board.

     (f) Lapse of Restrictions.  All restrictions imposed on Restricted Stock
         ---------------------                                               
shall lapse upon the expiration of the applicable Restriction Period and the
satisfaction of all conditions imposed by the Board.  The Board may determine,
as to any or all Restricted Stock Grants, that the restrictions shall lapse
without regard to any Restriction Period.

     7.  Withholding of Taxes
         --------------------

     (a) Required Withholding.  All Grants under the Plan shall be subject to
         --------------------                                                
applicable federal (including FICA), state and local tax withholding
requirements.  The Company may require the Grantee or other person receiving
shares under the Plan to pay to the Company the amount of any such taxes that
the Company is required to withhold with respect to the Grant, or the Company
may deduct from other wages paid by the Company the amount of any withholding
taxes due with respect to the Grant.

     (b) Election to Withhold Shares.  If the Board so permits, a Grantee may
         ---------------------------                                         
elect to satisfy the Company's income tax withholding obligation with respect to
an Option or Restricted Stock by having shares withheld up to an amount that
does not exceed the applicable withholding tax rate for federal (including
FICA), state and local tax liabilities.  The election must be in a form and
manner prescribed by the Board and shall be subject to the prior approval of the
Board.

     8.  Transferability of Grants
         -------------------------
<PAGE>
 
     (a) Nontransferability of Grants.  Except as provided below, only the
         ----------------------------                                     
Grantee may exercise rights under a Grant during the Grantee's lifetime.  A
Grantee may not transfer those rights except by will or by the laws of descent
and distribution or, with respect to Grants other than Incentive Stock Options,
if permitted in any specific case by the Board, pursuant to a domestic relations
order.  When a Grantee dies, the personal representative or other person
entitled to succeed to the rights of the Grantee ("Successor Grantee") may
exercise such rights. A Successor Grantee must furnish proof satisfactory to the
Company of his or her right to receive the Grant under the Grantee's will or
under the applicable laws of descent and distribution.

     (b) Transfer of Nonqualified Stock Options. Notwithstanding the foregoing,
         --------------------------------------                                
the Board may provide, in a Grant Instrument, that a Grantee may transfer
Nonqualified Stock Options to family members or other persons or entities
according to such terms as the Board may determine; provided that the
transferred Option shall continue to be subject to the same terms and conditions
as were applicable to the Option immediately before the transfer.

     9.  Shareholders Agreement/Right of First Refusal
         ---------------------------------------------

     As a condition to all Grants made to Grantees pursuant to this Plan, the
shares of Company Stock  distributed to him or her under this Plan shall be
subject to the shareholders agreement contained in this Section 9 and Section 10
below and any such other shareholders agreement the Board deems appropriate (as
permitted by Section 9(e) below).

     (a) Offer.  Prior to a Public Offering, if at any time an individual
         -----                                                           
desires to sell, encumber, or otherwise dispose of shares of Company Stock that
were distributed to him or her under this Plan and that are transferable, the
individual shall first offer the shares to the Company by giving the Company
written notice disclosing: (a) the name of the proposed transferee of the
Company Stock; (b) the certificate number and number of shares of Company Stock
proposed to be transferred or encumbered; (c) the proposed price; (d) all other
terms of the proposed transfer; and (e) a written copy of the proposed offer.
Within 60 days after receipt of such notice, the Company shall have the option
to purchase all or part of such Company Stock at the then current Fair Market
Value (as defined in Section 5(b)).

     (b) Sale.  In the event the Company (or a shareholder, as described below)
         ----                                                                  
does not exercise the option to purchase Company Stock, as provided above, the
individual shall have the right to sell, encumber, or otherwise dispose of his
shares of Company Stock on the terms of the transfer set forth in the written
notice to the Company, provided such transfer is effected within 15 days after
the expiration of the option period.  If the transfer is not effected within
such period, the Company must again be given an option to purchase, as provided
above.

     (c) Assignment of Rights.  The Board, in its sole discretion, may waive the
         --------------------                                                   
Company's right of first refusal pursuant to this Section 9 and the Company's
repurchase right pursuant to Section 10 below.  If the Company's right of first
refusal or repurchase right is so
<PAGE>
 
waived, the Board may, in its sole discretion, assign such right to the
remaining shareholders of the Company in the same proportion that each
shareholder's stock ownership bears to the stock ownership of all the
shareholders of the Company, as determined by the Board. To the extent that a
shareholder has been given such right and does not purchase his or her
allotment, the other shareholders shall have the right to purchase such
allotment on the same basis.

     (d) Public Offering.  On and after a Public Offering, the Company shall
         ---------------                                                    
have no further right to purchase shares of Company Stock under this Section 9
and Section 10 below, and their limitations shall be null and void.

     (e) Shareholder's Agreement.  Notwithstanding the foregoing, the Board may
         -----------------------                                               
require that a Grantee execute a shareholder's agreement, with such terms as the
Board deems appropriate, with respect to any Company Stock distributed pursuant
to this Plan, in which case the provisions of this Section 9 and Section 10
below shall not apply to such Company Stock.

     10. Shareholders Agreement/Purchase by the Company
         ----------------------------------------------

     Prior to a Public Offering, if a Grantee ceases to be employed by, or
provide service to, the Company, the Company shall have the right to purchase
all or part of any Company Stock distributed to him or her under this Plan at
its then current Fair Market Value (as defined in Section 5(b)) (or at such
other price as may be established in the Grant Instrument); provided, however,
that such repurchase shall be made in accordance with applicable accounting
rules to avoid adverse accounting treatment.

     11. Consequences of a Change of Control
         -----------------------------------

     (a) Notice and Acceleration.  Upon a Change of Control, unless the Board
         -----------------------                                             
determines otherwise, (i) the Company shall provide each Grantee with
outstanding Grants written notice of such Change of Control, (ii) all
outstanding Options shall automatically accelerate and become fully exercisable,
and (iii) the restrictions and conditions on all outstanding Restricted Stock
shall immediately lapse.

     (b) Assumption of Grants.  Upon a Change of Control where the Company is
         --------------------                                                
not the surviving corporation (or survives only as a subsidiary of another
corporation), unless the Board determines otherwise, all outstanding Grants
shall be assumed by, or replaced with comparable options or stock by, the
surviving corporation.

     (c) Other Alternatives.  Notwithstanding the foregoing, subject to
         ------------------                                            
subsection (d) below, in the event of a Change of Control, the Board may take
one or both of the following actions: the Board may (i) require that Grantees
surrender their outstanding Options in exchange for a payment by the Company, in
cash or Company Stock as determined by the Board, in an amount equal to the
amount by which the then Fair Market Value of the shares of Company Stock
subject to the Grantee's unexercised Options exceeds the Exercise Price of the
Options, or
<PAGE>
 
(ii) after giving Grantees an opportunity to exercise their outstanding Options,
terminate any or all unexercised Options at such time as the Board deems
appropriate. Such surrender or termination shall take place as of the date of
the Change of Control or such other date as the Board may specify.

     (d) Limitations.  Notwithstanding anything in the Plan to the contrary, in
         -----------                                                           
the event of a Change of Control, the Board shall not have the right to take any
actions described in the Plan (including without limitation actions described in
Subsection (c) above) that would make the Change of Control ineligible for
pooling of interests accounting treatment or that would make the Change of
Control ineligible for desired tax treatment if, in the absence of such right,
the Change of Control would qualify for such treatment and the Company intends
to use such treatment with respect to the Change of Control.

     12. Requirements for Issuance or Transfer of Shares
         -----------------------------------------------

     (a) Limitations on Issuance or Transfer of Shares.  No Company Stock shall
         ---------------------------------------------                         
be issued or transferred in connection with any Grant hereunder unless and until
all legal requirements applicable to the issuance or transfer of such Company
Stock have been complied with to the satisfaction of the Board.  The Board shall
have the right to condition any Grant made to any Grantee hereunder on such
Grantee's undertaking in writing to comply with such restrictions on his or her
subsequent disposition of such shares of Company Stock as the Board shall deem
necessary or advisable as a result of any applicable law, regulation or official
interpretation thereof, and certificates representing such shares may be
legended to reflect any such restrictions. Certificates representing shares of
Company Stock issued or transferred under the Plan will be subject to such stop-
transfer orders and other restrictions as may be required by applicable laws,
regulations and interpretations, including any requirement that a legend be
placed thereon.

     13. Amendment and Termination of the Plan
         -------------------------------------

     (a) Amendment.  The Board may amend or terminate the Plan at any time;
         ---------                                                         
provided, however, that the Board shall not amend the Plan without shareholder
approval if such approval is required by Section 162(m) of the Code.

     (b) Termination of Plan.  The Plan shall terminate on the day immediately
         -------------------                                                  
preceding the tenth anniversary of its effective date, unless the Plan is
terminated earlier by the Board or is extended by the Board with the approval of
the shareholders.

     (c) Termination and Amendment of Outstanding Grants.  A termination or
         -----------------------------------------------                   
amendment of the Plan that occurs after a Grant is made shall not materially
impair the rights of a Grantee unless the Grantee consents or unless the Board
acts under Section 20(b).  The termination of the Plan shall not impair the
power and authority of the Board with respect to an outstanding Grant. Whether
or not the Plan has terminated, an outstanding Grant may be
<PAGE>
 
terminated or amended under Section 20(b) or may be amended by agreement of the
Company and the Grantee consistent with the Plan.

     (d) Governing Document.  The Plan shall be the controlling document.  No
         ------------------                                                  
other statements, representations, explanatory materials or examples, oral or
written, may amend the Plan in any manner.  The Plan shall be binding upon and
enforceable against the Company and its successors and assigns.

     14. Funding of the Plan
         -------------------

     This Plan shall be unfunded.  The Company shall not be required to
establish any special or separate fund or to make any other segregation of
assets to assure the payment of any Grants under this Plan.  In no event shall
interest be paid or accrued on any Grant, including unpaid installments of
Grants.

     15. Rights of Participants
         ----------------------

     Nothing in this Plan shall entitle any Employee, Key Advisor, Non-Employee
Director or other person to any claim or right to be granted a Grant under this
Plan.  Neither this Plan nor any action taken hereunder shall be construed as
giving any individual any rights to be retained by or in the employ of the
Company or any other employment rights.

     16. No Fractional Shares
         --------------------

     No fractional shares of Company Stock shall be issued or delivered pursuant
to the Plan or any Grant.  The Board shall determine whether cash, other awards
or other property shall be issued or paid in lieu of such fractional shares or
whether such fractional shares or any rights thereto shall be forfeited or
otherwise eliminated.

     17. Headings
         --------

     Section headings are for reference only.  In the event of a conflict
between a title and the content of a Section, the content of the Section shall
control.

     18. Effective Dates.
         --------------- 

     (a) Effective Date of the Plan.  Subject to the approval of the Company's
         --------------------------                                           
shareholders, the Plan shall be effective on December 18, 1996.

     (b) Public Offering.  The provisions of the Plan that refer to a Public
         ---------------                                                    
Offering, or that refer to, or are applicable to persons subject to, section 16
of the Exchange Act or section 162(m) of the Code, shall be effective, if at
all, upon the initial registration of the Company Stock under section 12(g) of
the Exchange Act, and shall remain effective thereafter for so long as such
stock is so registered.
<PAGE>
 
     19. Miscellaneous
         -------------

     (a) Grants in Connection with Corporate Transactions and Otherwise.
         --------------------------------------------------------------   
Nothing contained in this Plan shall be construed to (i) limit the right of the
Board to make Grants under this Plan in connection with the acquisition, by
purchase, lease, merger, consolidation or otherwise, of the business or assets
of any corporation, firm or association, including Grants to employees thereof
who become Employees of the Company, or for other proper corporate purposes, or
(ii) limit the right of the Company to grant stock options or make other awards
outside of this Plan.  Without limiting the foregoing, the Board may make a
Grant to an employee of another corporation who becomes an Employee by reason of
a corporate merger, consolidation, acquisition of stock or property,
reorganization or liquidation involving the Company or any of its subsidiaries
in substitution for a stock option or restricted stock grant made by such
corporation.  The terms and conditions of the substitute grants may vary from
the terms and conditions required by the Plan and from those of the substituted
stock incentives.  The Board shall prescribe the provisions of the substitute
grants.

     (b) Compliance with Law.  The Plan, the exercise of Options and the
         -------------------                                            
obligations of the Company to issue or transfer shares of Company Stock under
Grants shall be subject to all applicable laws and to approvals by any
governmental or regulatory agency as may be required. With respect to persons
subject to Section 16 of the Exchange Act, it is the intent of the Company that
the Plan and all transactions under the Plan comply with all applicable
provisions of Rule 16b-3 or its successors under the Exchange Act.  The Board
may revoke any Grant if it is contrary to law or modify a Grant to bring it into
compliance with any valid and mandatory government regulation.  The Board may
also adopt rules regarding the withholding of taxes on payments to Grantees.
The Board may, in its sole discretion, agree to limit its authority under this
Section.

     (c) Governing Law.  The validity, construction, interpretation and effect
         -------------                                                        
of the Plan and Grant Instruments issued under the Plan shall exclusively be
governed by and determined in accordance with the law of the Commonwealth of
Pennsylvania.

           (a) SCHEDULE 3.20 contains a complete list of all Benefit Plans
sponsored or maintained by the Company or under which the Company is obligated.

such Benefit Plan documents and all other material documents relating thereto,
including (if applicable) all summary plan descriptions, summary annual reports
and insurance contracts, (ii) accurate and complete detailed summaries of all
unwritten Benefit Plans, (iii) accurate and complete copies of the most recent
financial statements and actuarial reports with respect to all such Benefit
Plans for which financial statements or actuarial reports are required or have

all such Benefit Plans (for which annual reports are required) prepared within
the last three years.  Each such Benefit Plan providing benefits that are funded
through a policy of insurance is indicated by the word "insured" placed by the
listing of the Benefit Plan in the SCHEDULE 3.20.

           (b) To the Knowledge of any of the Shareholders, all such Benefit
Plans conform (and at all times have conformed) in all material respects to, and
are being administered and operated (and have at all time been administered and
operated) in material compliance with, the requirements of ERISA, the Code and
all other applicable Laws.  All returns, reports and disclosure statements
required to be made under ERISA and the Code with respect to all such Benefit
Plans have been timely filed or delivered.  To the Knowledge of any of the
Shareholders, there have not been any "prohibited transactions," as such term is
defined in Section 4975 of the Code or Section 406 of ERISA involving any of the
Benefit Plans, that could subject any Shareholder or the Company to any material
penalty or tax imposed under the Code or ERISA.

           (c) Except as is set forth in SCHEDULE 3.20, any such Benefit Plan
that is intended to be qualified under Section 401(a) of the Code and exempt
from tax under Section 501(a) of the Code has been determined by the Internal
Revenue Service to be so qualified or an 

                                      14
<PAGE>
 
application for such determination is pending. Any such determination that has
been obtained remains in effect and has not been revoked, and with respect to
any application that is pending, the Company does not have any reason to suspect
that such application for determination will be denied. Nothing has occurred
since the date of any such determination that is reasonably likely to affect
adversely such qualification or exemption, or result in the imposition of excise
taxes or income taxes on unrelated business income under the Code or ERISA with
respect to any such Benefit Plan.

           (d)  The Company does not sponsor a defined benefit plan subject to
Title IV of ERISA, nor does it have a current or contingent obligation to
contribute to any multiemployer plan (as defined in Section 3(37) of ERISA). The
Company does not have any liability with respect to any employee benefit plan
(as defined in Section 3(3) of ERISA) other than with respect to such Benefit
Plans.

           (e)  There are no pending or, to Shareholders' Knowledge, any
threatened claims by or on behalf of any such Benefit Plans, or by or on behalf
of any individual participants or beneficiaries of any such Benefit Plans,
alleging any breach of fiduciary duty on the part of the Company or any of its
officers, directors or employees under ERISA or any other applicable
regulations, or claiming benefit payments (other than those made in the ordinary
operation of such plans), nor is there, to Shareholders's Knowledge, any basis
for such claim.  The Benefit Plans are not the subject of any pending (or to
Shareholders's Knowledge, any threatened) investigation or audit by the Internal
Revenue Service or the Department of Labor.

           (f)  The Company has timely made all required contributions under
such Benefit Plans.

           (g)  With respect to any such Benefit Plan that is an employee
welfare benefit plan (within the meaning of Section 3(1) of ERISA) (a "Welfare
Plan") and except as specified in SCHEDULE 3.20, (i) each Welfare Plan for which
contributions are claimed by the Company as deductions under any provision of
the Code complies with all applicable requirements pertaining to such deduction,
(ii) with respect to any welfare benefit fund (within the meaning of Section 419
of the Code) related to a Welfare Plan, there is no disqualified benefit (within
the meaning of Section 4976(b) of the Code) that would result in the imposition
of a tax under Section 4976(a) of the Code, (iii) any Benefit Plan that is a
group health plan (within the meaning of Section 4980B(g)(2) of the Code)
complies, and in each and every case has complied, with all of the applicable
requirements of Section 4980B of the Code, ERISA, Title XXII of the Public
Health Service Act and the Social Security Act, and (iv) all Welfare Plans may
be amended or terminated at any time on or after the Closing Date. Except as
specified in SCHEDULE 3.20, no Benefit Plan provides any health, life or other
welfare coverage to employees of the Company beyond termination of their
employment with the Company by reason of retirement or otherwise, other than
coverage as may be required under Section 4980B of the Code or Part 6 of ERISA,
or under the continuation of coverage provisions of the laws of any state or
locality.

jointly and severally, shall indemnify and hold harmless Buyer and its
successors and assigns, and their respective officers, directors, employees,
shareholders, agents, Affiliates and any Person who 

                                      23
<PAGE>
 
controls any of such Persons within the meaning of the Securities Act or the
Exchange Act (each, a "Buyer Indemnified Party") from and against any
liabilities, claims, demands, judgments, losses, costs, damages or expenses
whatsoever (including reasonable attorneys', consultants' and other professional
fees and disbursements of every kind, nature and description incurred by such
Buyer Indemnified Party in connection therewith including consequential damages)
(collectively, "Damages") that such Buyer Indemnified Party may sustain, suffer

from and against any Damages that such Shareholder Indemnified Party may
sustain, suffer or incur and that result from, arise out of or relate to any
breach of any of the respective representations, warranties, covenants or
agreements of Buyer contained in this Agreement.  Buyer shall not be liable

                                      24
<PAGE>
 
claims made by Buyer Indemnified Party hereunder, and taking any other action
that is specifically delegated to the Holders' Representative hereunder. Buyer
shall give notice under Section 10.4 of any claim for indemnification against
the Shareholders to Shareholders and the Holders' Representative, and only the
Holders' Representative shall be empowered following such notice to respond to
or take any other action on behalf of the Shareholders with respect to the
claim. Shareholders shall be bound by any and all actions taken by the Holders'
Representative on their behalf in accordance with this Agreement.

          (b) Buyer shall be entitled to rely exclusively upon any
communications or writings given or executed by the Holders' Representative and
shall not be liable in any manner whatsoever for any action taken or not taken
in reliance upon the actions taken or not taken or communications or writings
given or executed by the Holders' Representative.  Buyer shall be entitled to
disregard any notices or communications given or made by the Shareholders unless
given or made through the Holders' Representative.

          (c) In the event of the death of the Holders' Representative or his
inability to perform his functions hereunder, the Shareholders who immediately
prior to the Closing owned a majority of Shares shall choose another Holders'
Representative.

          (d) The Holders' Representative shall not be liable to any Shareholder
or any other party for any action taken or omitted to be taken by him as
Holders' Representative except, in the case of willful misconduct or gross
negligence.  Shareholders jointly indemnify the Holders' Representative and hold
him harmless from and against any loss, liability or expense of any nature
incurred by the Holders' Representative arising out of or in connection with the
administration of his duties as Holders' Representative, including reasonable
legal fees and other costs and expenses of defending or preparing to defend
against any claim or liability in the premises, unless such loss, liability or
expense shall be caused by the Holders' Representative's willful misconduct or
gross negligence.

    10.4  Procedure for Claims.
          -------------------- 

          (a) Any Person that desires to seek indemnification under any part of
this Section 10 (each, an "Indemnified Party") shall give notice (a "Claim
Notice") to each party responsible or alleged to be responsible for
indemnification hereunder (an "Indemnitor") prior to any applicable Expiration
Date specified below.  Such notice shall explain with specificity the nature of
the claim, the specific section of this Agreement to which the claim relates and
the parties known to be invoked, and shall specify the amount thereof.  If the
matter to which a claim relates shall not have been resolved as of the date of
the Claim Notice, the Indemnified Party shall estimate the amount of the claim
in the Claim Notice, but also specify therein that the claim has not yet been
liquidated (an "Unliquidated Claim").  If an Indemnified Party gives a Claim
Notice for an Unliquidated Claim, the Indemnified Party shall also give a second
Claim Notice (the "Liquidated Claim Notice") within 60 days after the matter
giving rise to the claim becomes finally resolved, and the Second Claim Notice
shall specify the amount of the claim.  Each 

                                      25
<PAGE>
 
Indemnitor to which a Claim Notice is given shall respond to any Indemnified
Party that has given a Claim Notice (a "Claim Response") within 60 days (the
"Response Period") after the later of (i) the date that the Claim Notice is
given or (ii) if a Claim Notice is first given with respect to an Unliquidated
Claim, the date on which the Liquidated Claim Notice is given. Any Claim Notice
or Claim Response shall be given in accordance with the notice requirements
hereunder, and any Claim Response shall specify whether or not the Indemnitor
giving the Claim Response disputes the claim described in the Claim Notice. If
any Indemnitor fails to give a Claim Response within the Response Period, such
Indemnitor shall be deemed not to dispute the claim described in the related
Claim Notice. If any Indemnitor elects not to dispute a claim described in a
Claim Notice, whether by failing to give a timely Claim Response or otherwise,
then the amount of such claim shall be conclusively deemed to be an obligation
of such Indemnitor. For the purposes of the immediately preceding sentence, an
Indemnitor's failure to give a timely Claim Response shall not be deemed an
election not to dispute a Claim Notice unless the Indemnified Party shall have
given a second Claim Notice after expiration of the Response Period and another
20 days after the date on which the Indemnified Party shall have given such
second Claim Notice shall have expired without the Indemnitor's having given a
Response Notice within such period.

           (b) If any Indemnitor shall be obligated to indemnify an Indemnified
Party hereunder, such Indemnitor shall pay to such Indemnified Party within 30
days after the last day of the Claim Response Period the amount to which such
Indemnified Party shall be entitled.  If there shall be a dispute as to the
amount or manner of indemnification under this Section 10, the Indemnified Party
may pursue whatever legal remedies may be available for recovery of the Damages
claimed from any Indemnitor in accordance with the arbitration provisions of
this Agreement.  If any Indemnitor fails to pay all or part of any
indemnification obligation when due, then such Indemnitor Party shall also be
obligated to pay to the applicable Indemnified Party interest on the unpaid
amount for each day during which the obligation remains unpaid at an annual rate
equal to the Prime Rate,  and the Prime Rate in effect on the first business day
of each calendar quarter shall apply to the amount of the unpaid obligation
during such calendar quarter.

     10.5  Claims Period.  Any claim for indemnification under this Section 10
           -------------                                                      
shall be made by giving a Claim Notice under Section 10.4 on or before the first
anniversary of the Closing Date (the "Expiration Date").  So long as an
Indemnified Party gives a Claim Notice for an Unliquidated Claim on or before
the Expiration Date, such Indemnified Party shall be entitled to pursue its
rights to indemnification regardless of the date on which such Indemnified Party
gives the related Liquidated Claim Notice.

     10.6  Third Party Claims.
           ------------------ 

           (a) If any third party shall notify any Indemnified Party with
respect to any actions, suits or other administrative or judicial proceedings
(each, an "Action") which may give rise to a claim for indemnification against
any Indemnifying Party under this Section 10, then the 

                                      26
<PAGE>
 
Indemnified Party shall promptly (and in any event within five Business Days'
after receiving notice of the Action) notify each Indemnifying Party thereof in
writing.

          (b) Any Indemnifying Party will have the right to assume and
thereafter conduct the defense of the Action with counsel of his or its choice
reasonably satisfactory to the Indemnified Party; provided, however, that the
Indemnifying Party will not consent to the entry of any judgment or enter into
any settlement with respect to the Action without the prior written consent of
the Indemnified Party (which consent shall not be unreasonably withheld) unless
the judgment or proposed settlement involves only the payment of money damages
and does no impose an injunction or other equitable relief upon the Indemnified
Party.

          (c) Unless and until an Indemnifying Party assumes the defense of the
Action, the Indemnified Party may defend against the Action in any manner he or
it reasonably may deem appropriate.

          (d) In no event will the Indemnified Party consent to the entry of any
judgment or enter into any settlement with respect to any Action without the
prior written consent of each of the Indemnifying Parties (which consent shall
not be unreasonably withheld).

nonappealable;

          (d) By Buyer, if any Shareholder shall have breached, or failed to
comply with, any of its or his obligations under this Agreement or any
representation or warranty made by any Shareholder shall have been incorrect

[***] = Confidential Treatment Requested for Redacted Portions of Document

                             SPONSORSHIP AGREEMENT

This agreement ("Agreement") is entered into as of the 30th day of June, 1998
("Effective Date"), by and between Excite, Inc., a California corporation,
located at 555 Broadway, Redwood City, California 94063 ("Excite"), and
VerticalNet, Inc., a Pennsylvania corporation, located at 2 Walnut Grove Drive,
Suite 150, Horsham, Pennsylvania 19044 ("Client").

                                    RECITALS

A.   Excite maintains a site on the Internet at http://www.excite.com (the
     "Excite Site") and owns, manages or is authorized to place advertising on
     affiliated sites on the Internet worldwide (collectively, the "Excite
     Network") which, among other things, allow its users to search for and
     access content and other sites on the Internet.  For purposes of this
     Agreement, the parties hereby acknowledge that the Excite Network does not
     include the site on the Internet located at http://home.netscape.com and/or
     other URLs or locations designated by Netscape Communications Corporation.

B.   Within the Excite Site, Excite currently organizes certain content into
     topical channels (the "Channels").  Excite also maintains and/or manages
     certain Web pages which may be delivered to users worldwide via email or
     Internet "push" technologies (collectively, "Broadcast Pages") which may
     incorporate content supplied to Excite by third parties for the purpose of
     providing value to Excite users and providing access to the content,
     products and/or services of such third parties.

C.   Excite also makes available to its users a number of community and
     communications services, including chat, email, bulletin boards and instant
     messaging.

D.   Client is engaged in the business of creating and operating "vertical trade
     communities" with a site on the Internet located at
     http://www.verticalnet.com (the "Client Site"). Client also owns or has the
     right to distribute certain content of interest to industrial community
     users through a variety of sites on the Internet linked from the Client
     Site.

E.   Client wishes to promote its business to Excite users through promotions
     and advertising in various portions of the Excite Network, and establish
     and maintain related co-branded pages on the Excite Site.

Therefore, the parties agree as follows:

1.   SPONSORSHIP AND ADVERTISING
<PAGE>
 
     a)   Excite and Client will cooperate in good faith to identify and then
          implement, commencing on the Launch Date (as defined below),
          appropriate sponsorship and promotional opportunities across the
          Excite Site. Such opportunities may include sponsorship text and/or
          graphic links, sponsorship boxes and promotional boxes. The parties
          agree that they may be located within communities, directories and/or
          industry listings on various Channels and other locations within the
          Excite Site.

     b)   The parties recognize that Excite is currently in the process of
          developing its community and communications services and that
          sponsorship, promotional and advertising opportunities will vary over
          time and from service to service. Excite will display Client's banner
          advertising in the Excite Chat client in rotation in the areas related
          to Client's businesses for the term of the Agreement. Excite will
          display Client's banner advertising in rotation on the pages of the
          Excite Site on which the Excite bulletin board discussions are
          displayed that include areas related to Client's businesses.

     c)   Excite will display Client's banner advertising on Excite Search
          results pages in response to mutually determined keywords, subject to
          availability. An initial list of such keywords is attached as Exhibit
                                                                        -------
          A to this Agreement. Client will provide Excite an updated list of
          -   
          keywords during the term of the Agreement. If keyphrase advertising
          becomes available on the Excite Site, Excite will display Client's
          banner advertising on Excite Search results pages in response to
          mutually determined keyphrases, subject to availability.

     d)   Excite and Client agree to negotiate in good faith the terms and
          conditions of Client's participation in sponsorship and advertising
          opportunities on a vertical markets/business-to-business channel on
          the Excite Site, if launched. If such a channel is launched, its home
          page will include mutually agreed upon categories related to Client's
          businesses and Client's Co-Branded Pages will be no more than one
          level down from the home page of such vertical markets/business-to-
          business channel.

2.   CONTENT AND CO-BRANDED PAGES; "TRY THESE FIRST" LINKS

     a)   Client will provide to Excite certain categories of content (the
          "Content"). The Content may be incorporated into certain pages in the
          Excite Network and reasonable excerpts or portions of the Content may
          be incorporated into Broadcast Pages, at Excite's discretion. Client
          and Excite will determine mutually agreeable methods for the
          transmission and incorporation of updates to the Content. Excite will
          have sole control over the "look

                                       2
<PAGE>
 
          and feel" of the Excite Network. Client and Excite will mutually agree
          in advance as to the substance and the intended display of the
          Content. Excite will have sole control over the content, composition,
          "look and feel" and distribution of the Broadcast Pages. Client will
          have sole responsibility for providing, at its expense, the Content to
          Excite.

     b)   The promotional placements described in Section 1 will link to co-
          branded pages in the Excite Site (the "Co-Branded Pages") which will
          incorporate the content that is to be provided by Client to Excite
          (the "Co-Branded Content"). Exhibit B attached to this Agreement is a
                                      ---------  
          mock-up that is illustrative of the appearance of such Co-Branded
          Pages. Excite agrees to design and create up to thirty (30) such Co-
          Branded Pages which will reside completely on the Excite Site for the
          term of this Agreement, seventeen (17) of which have already been
          identified by the parties as specified in Exhibit C of this Agreement.
                                                    ----------
          Each Co-Branded Page will display the name and/or brands of Client and
          Excite. Client will be the dominant and preferred sponsor on each of
          the Co-Branded Pages. Furthermore, Excite agrees that Client's Co-
          Branded Content will be displayed above the fold on the Co-Branded
          Pages. For purposes of this Agreement, "above the fold" means the
          location within the portion of a page that is designed to be visible
          on a standard computer screen with a resolution of 640 pixels by 480
          pixels without requiring the user to scroll horizontally or vertically
          through the page. Excite will have sole responsibility for maintaining
          the Co-Branded Pages during the term of this Agreement, except that
          Client will have sole responsibility for providing to Excite all Co-
          Branded Content and any updates thereto. Each Co-Branded Page will
          include one or more links to the Excite Network.

     c)   Excite may sell banner advertising on the Co-Branded Pages. Excite
          will not sell or barter banner advertising on the Co-Branded Pages to
          Client's competitors including, but not limited to, the companies
          identified in Exhibit D or any other company promoting itself as a
                        ---------
          provider of industrial trade communities. Not more than once per
          quarter, Client may update this list of competitors. Within twenty-
          four (24) hours of receiving Client's written update, Excite will
          remove any banners advertising any of Client's listed competitors
          displayed on the Co-Branded Pages. Excite will retain [***] percent
          ([***]%) of the revenue generated from banner advertising on the Co-
          Branded Pages. Excite agrees that it will not display on the Co-
          Branded Pages any banners advertising or promoting any industrial
          auction services, other than Client's.

     d)   Client may sell off-banner sponsorship and off-banner promotional
          placements, including but not limited to links, on the Co-Branded
          Pages Client will not sell or barter sponsorship opportunities on the
          Co-Branded Pages to Excite's competitors including, but not limited
          to, AltaVista, HotBot, lnfoseek, Lycos, Search.com, Snap and Yahoo!,
          or any other Web site promoting itself as a provider of Internet
          search and navigation services. Not more than once per quarter, Excite

          links on the Excite Search results page.

         authority to create any obligation or responsibility on behalf of the
         other.

11.8     Severability. If any provision of this Agreement shall be held by a
         ------------
         court of competent jurisdiction to be contrary to law, such provision

         objectives of the original provision to the fullest extent allowed by
         law 
<PAGE>
 
         and the remaining provisions of this Agreement shall remain in full
         force and effect.

11.9     Complete Understanding. This Agreement, including all Exhibits attached

         hereto and hereby incorporated by reference, constitutes the final,

         agreement, either written or oral.

11.10    Force Majeure. Except with respect to obligations to make payments
         -------------
         hereunder, neither party shall be deemed in default hereunder, nor

         of the termination of such event. During the period that the
         performance by Junglee of its obligations under this Agreement has been
         suspended by reason of an event of Force Majeure, VerticalNet may
         likewise suspend its payment obligations hereunder. In the event that

         prior to the effective time of such termination.


                            [Signature Page Follows]

        -----------------------------                                     
contained in this Section 7.4, the indemnification obligations of the Seller and
the Purchaser shall be limited as follows:

          (a)  Neither the Seller Parties nor the Purchaser Parties shall be
entitled to seek indemnification under this Section 7 until the aggregate of all
Damages incurred by such parties exceeds $31,000 (the "Basket Amount").  Once
                                                       -------------         
the Basket Amount has been exceeded, the indemnifying party shall be liable to
the indemnified parties for the full amount of such Damages; and

          (b)  Neither the Seller nor the Purchaser shall be liable for payments
of indemnification under this Section 7 in an aggregate amount greater than
$450,000;

provided, however, that, notwithstanding anything contained herein to the
- --------  ------- 
contrary, the limitations on the indemnification obligations of the parties
hereto contained in this Section 7.4 shall not apply with respect to Damages
arising under (i) fraud or fraud in the inducement or (ii) the intentional
breach of any covenant or agreement contained herein.

     e) Procedure for Indemnification.  If any claim is made against a party (an
        -----------------------------                                           
"indemnified party") that, if sustained, would give rise to a liability of
 -----------------                                                        
another party (the "indemnifying party") under this Agreement, the indemnified
                    ------------------                                        
party shall promptly cause notice of the claim to be delivered to the
indemnifying party along with all of the facts, information or materials
relating to such claim of which the indemnified party is aware and shall afford
the indemnifying party and its counsel, at the indemnifying party's sole
expense, the opportunity to defend or settle the claim.

          i)  The indemnifying party shall have 15 business days after delivery
thereof to elect, in writing to the indemnified party, to defend or settle the
claim, exercising reasonable business judgment, at its own expense.   Until
written notice electing to defend or settle any claim that, if sustained, would
give rise to a liability under this Agreement, the indemnified party may take,
at the expense of the indemnifying party, any action it reasonably believes
necessary to preserve its rights with respect to such claim, after promptly
notifying the indemnifying party of its intention to take such action and the
indemnifying party does not elect to take such other action.

                                       10
<PAGE>
 
          ii)  If the indemnifying party shall so elect to defend or settle the
claim, the indemnifying party may not settle such claim without the prior
written consent of the indemnified party; provided that, if the indemnified
                                          --------                         
party does not consent to such a settlement, the indemnifying party's liability
to indemnify the indemnified party for such claim shall be limited to the
expenses and costs reasonably necessary to preserve its rights to such claim
(other than any costs of counsel retained by the indemnified party solely to
monitor the indemnifying party's obligations hereunder) that the indemnified
party has incurred up to the time of the proposed settlement plus the amount of
the proposed settlement.  The indemnified party agrees to use commercially
reasonable efforts to cooperate with the indemnifying party in defending any
claim, at the indemnifying party's expense.

          iii) If the indemnifying party shall fail to so elect to defend or
settle such claim (exercising reasonable business judgment) at its own expense,
within 30 days of delivery of notice of the claim, or otherwise so fail to
defend or settle the claim, the indemnified party shall have the right, but not
the obligation, to undertake the defense of and to settle (exercising reasonable
business judgment) the claim on behalf, for the account and at the risk, of the
so failing party.  The indemnified party shall use commercially reasonable
efforts to settle any such claim at commercially reasonable amounts determined
in good faith by the indemnifying party.

          iv)  In the event the indemnified party should have a claim against
the indemnifying party that does not involve a claim or demand by a third party,
the indemnified party shall promptly cause notice of such claim to be delivered
to the indemnifying party. The indemnifying party shall have 15 business days
after delivery thereof to elect, in writing to the indemnified party, to defend
or settle the claim, exercising reasonable business judgment, at its own
expense. If the indemnifying party does not notify the indemnified party within
20 days after the indemnified party's notice that it disputes such claim, the
amount of such claim shall be conclusively deemed as a liability of the
indemnifying party. If the indemnifying party disputes such claim, the
indemnifying party and the indemnified party shall attempt in good faith for a
period of 30 days to settle any such dispute.

     f) Other Remedies.  The indemnity of this Section 7 shall be the exclusive
        --------------                                                         
remedy of any party for a breach, misrepresentation, nonfulfillment, or default
in the performance of the representations, warranties, covenants, or agreements
of this Agreement or any certificate, exhibit, or schedule contemplated hereby,
except in the event of actual fraud or fraud in the inducement; provided,
                                                                -------- 
however, Section 6.1(c) shall govern the remedies of Purchaser against Seller
- -------                                                                      
and the Key Employees for a breach by them of the covenants contained in Section
6.1 only.

8. Miscellaneous.

THIS WARRANT AND THE SECURITIES ISSUABLE UPON ITS EXERCISE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT

DATE: NOVEMBER 25, 1998                            WARRANT TO PURCHASE
                                          40,000 OR 60,000 SHARES OF COMMON
STOCK


VERTICALNET, INC.

COMMON STOCK PURCHASE WARRANT


          VerticalNet, Inc., a Pennsylvania corporation (the "Company"), hereby
certifies that, for value received, Progress Capital, Inc., a Delaware
corporation (the "holder"), or assigns, is entitled, subject to the terms set
forth below, to purchase from the Company, at any time and from time to time
during the period beginning on the earlier of (a) the effective date of the
registration statement for an underwritten public offering of the Company's
common stock, par value $.01 per share, (b) the closing date of the next round
of equity financing in the Company raising not less than $5,000,000 from third
party investors other than holder (the "Next Round Financing") and (c) March 31,
1999 (the earliest of clauses (a), (b) and (c) being hereafter referred to as
the "First Exercise Date"), and ending on November 25, 2008, an aggregate of (x)
if  the $2,000,000 Promissory Note given to the holder by the Company (the
"Promissory Note") is repaid in full on or prior to the First Exercise Date,
FORTY THOUSAND (40,000) or (y) if the Promissory Note is repaid in full after
the First Exercise Date, SIXTY THOUSAND (60,000), fully paid and non-assessable
shares of the common stock, par value $.01 per share, of the Company at the
"Purchase Price" (as hereinafter defined), subject to the provisions of
Paragraph 3 hereof.  "Purchase Price" shall mean (x) if either of the
transactions specified in clauses (a) and (b) above occur before May 31, 1999,
the price per share paid for shares of common stock, par value $.01 per share,
of the Company in such transaction (before underwriting discounts and
commissions) or (y) if neither of the events specified in clauses (a) and (b)
above occur before May 31, 1999, $1.80 per share.  "Common Stock" shall mean,
unless the context otherwise requires, the stock or other securities or property
at the time deliverable upon the exercise of this Warrant.  Notwithstanding the
foregoing, the Purchase Price and the number and character of shares issuable
under this Warrant are subject to adjustment as set forth in Paragraph 3.  This
Warrant is herein called the "Warrant."

          1.  EXERCISE OF WARRANT.  The purchase rights evidenced by this
Warrant shall be exercised by the holder hereof surrendering this Warrant, with
the form of subscription at the end hereof duly executed by such holder, to the
Company at its office at Two Walnut Grove Drive, Suite 150, Horsham,
Pennsylvania 19044, or such other address as the Company may specify 
<PAGE>
 
by written notice to the registered holder hereof, accompanied by payment, in
cash, by certified or official bank check or by wire transfer of an amount equal
to the Purchase Price multiplied by the number of shares being purchased
pursuant to such exercise of the Warrant.

          1.1  Partial Exercise.  This Warrant may be exercised for less than
               ----------------                                              
the full number of shares of Common Stock, in which case the number of shares
receivable upon the exercise of this Warrant as a whole, and the sum payable
upon the exercise of this Warrant as a whole, shall be proportionately reduced.
Upon any such partial exercise, the Company at its expense will forthwith issue
to the holder hereof a new Warrant or Warrants of like tenor calling for the
number of shares of Common Stock as to which rights have not been exercised,
such Warrant or Warrants to be issued in the name of the holder hereof or his
nominee (upon payment by such holder of any applicable transfer taxes).
 
          1.2. Net Issue Exercise.
               ------------------ 

               (1)  In lieu of exercising this Warrant, holder may elect to
receive shares equal to the value of this Warrant (or the portion thereof being
canceled) by surrender of this Warrant at the principal office of the Company
together with notice of such election in which event the Company shall issue to
holder that number of shares of the Company's Common Stock computed using the
following formula:

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

          X =  the number of shares of Common Stock to be issued to Holder.

          Y =  the number of shares of Common Stock purchasable under
               this Warrant

          A =  the fair market value of one share of the Company's Common Stock.

          B =  the Purchase Price (as adjusted to the date of such
calculations).

               (2)  For purposes of this Section, the fair market value of one
share of the Company's Common Stock shall be based on the average of the closing
bid and asked prices of the Summary or the closing price quoted in the Over-The-
Counter Market Summary or the closing price quoted on any exchange on which the
Common Stock is listed, whichever is applicable, as published in the Eastern
Edition of The Wall Street Journal for the ten trading days prior to the date of
determination of fair market value. If the Common Stock is not traded Over-The-
Counter or on an exchange, the fair market value of the Company's Common Stock
shall be the price per share which the Company could obtain from a willing buyer
for shares sold by the Company from authorized but unissued shares, as such
price shall be agreed by the Company and the holder.

          2.  DELIVERY OF STOCK CERTIFICATES ON EXERCISE.  As soon as
practicable after the exercise of this Warrant and payment of the Purchase
Price, and in any event within ten (10) days thereafter, the Company, at its
expense, will cause to be issued in the name of and delivered to the holder
hereof a certificate or certificates for the number of fully paid and non-
assessable shares or other securities or property to which such holder shall be
entitled upon such exercise, plus, in lieu of any fractional share to which such
holder would otherwise be entitled, cash in an amount determined in accordance
with Paragraph 3.9 hereof.  The Company agrees that the shares so purchased
shall be deemed to be issued to the holder hereof as the record owner of such
shares as of the close of business on the date on which this Warrant shall have
been surrendered and payment made for such shares as aforesaid.

          3.  ANTI-DILUTION PROVISIONS AND OTHER ADJUSTMENTS.  In order to
prevent dilution of the right granted hereunder, the Purchase Price shall be
subject to adjustment from time to time in accordance with this Paragraph 3.
Upon each adjustment of the Purchase Price pursuant to this Paragraph 3, the
registered Holder of this Warrant shall thereafter be entitled to acquire upon
exercise, at the Purchase Price resulting from such adjustment, the number of
shares of the Company's Common Stock obtainable by multiplying the Purchase
Price in effect immediately prior to such adjustment by the number of shares of
the Company's Common Stock acquirable immediately prior to such adjustment and
dividing the product thereof by the Purchase Price resulting from such
adjustment.

          3.1.  Adjustment for Issue or Sale of Common Stock at Less than
                ---------------------------------------------------------
Purchase Price. Except as provided in Paragraph 3.2 or 3.5 below, if and
- --------------                                                          
whenever on or after the date of issuance hereof the Company shall issue or
sell, or shall in accordance with subparagraphs 3.1(1) to (9), inclusive, be
deemed to have issued or sold, any shares of its Common Stock for a
consideration per share less than the Purchase Price in effect immediately prior
to the time of such issue or sale, then forthwith upon such issue or sale (the
"Triggering Transaction"), the Purchase Price shall, subject to subparagraphs
(1) to (9) of this Paragraph 3.1, be reduced to the Purchase Price (calculated
to the nearest tenth of a cent) determined by dividing:

                (i)  an amount equal to the sum of (x) the product derived by
     multiplying the Number of Common Shares Deemed Outstanding immediately
     prior to such Triggering Transaction by the Purchase Price then in effect,
     plus (y) the consideration, if any, received by the Company upon
     consummation of such Triggering Transaction, by

               (ii)  an amount equal to the sum of (x) the Number of Common
     Shares Deemed Outstanding immediately prior to such Triggering Transaction
     plus (y) the number of shares of Common Stock issued (or deemed to be
     issued in accordance with subparagraphs 3.1(1) to (9)) in connection with
     the Triggering Transaction.

          For purposes of this Paragraph 3, the term "Number of Common Shares
Deemed Outstanding" at any given time shall mean the sum of (i) the number of
shares of the Company's 

                                       3
<PAGE>
 
Common Stock outstanding at such time, and (ii) the number of shares of the
Company's Common Stock deemed to be outstanding under subparagraphs 3.1(1) to
(9), inclusive, at such time.

          For purposes of determining the adjusted Purchase Price under this
Paragraph 3.1, the following subsections (1) to (9), inclusive, shall be
applicable:

          (1)  In case the Company at any time shall in any manner grant
     (whether directly or by assumption in a merger or otherwise) any rights to
     subscribe for or to purchase, or any options for the purchase of, Common
     Stock or any stock or other securities convertible into or exchangeable for
     Common Stock (such rights or options being herein called "Options" and such
     convertible or exchangeable stock or securities being herein called
     "Convertible Securities"), whether or not such Options or the right to
     convert or exchange any such Convertible Securities are immediately
     exercisable and the price per share for which the Common Stock is issuable
     upon exercise, conversion or exchange (determined by dividing (x) the total
     amount, if any, received or receivable by the Company as consideration for
     the granting of such Options, plus the minimum aggregate amount of
     additional consideration payable to the Company upon the exercise of all
     such Options, plus, in the case of such Options which relate to Convertible
     Securities, the minimum aggregate amount of additional consideration, if
     any, payable upon the issue or sale of such Convertible Securities and upon
     the conversion or exchange thereof, by (y) the total maximum number of
     shares of Common Stock issuable upon the exercise of such Options or the
     conversion or exchange of such Convertible Securities) shall be less than
     the Purchase Price in effect immediately prior to the time of the granting
     of such Option, then the total maximum amount of Common Stock issuable upon
     the exercise of such Options, or, in the case of Options for Convertible
     Securities, upon the conversion or exchange of such Convertible Securities,
     shall (as of the date of granting of such Options) be deemed to be
     outstanding and to have been issued and sold by the Company for such price
     per share. No adjustment of the Purchase Price shall be made upon the
     actual issue of such shares of Common Stock or such Convertible Securities
     upon the exercise of such Options, except as otherwise provided in
     subparagraph (3) below.

          (2)  In case the Company at any time shall in any manner issue
     (whether directly or by assumption in a merger or otherwise) or sell any
     Convertible Securities, whether or not the rights to exchange or convert
     thereunder are immediately exercisable, and the price per share for which
     Common Stock is issuable upon such conversion or exchange (determined by
     dividing (x) the total amount received or receivable by the Company as
     consideration for the issue or sale of such Convertible Securities, plus
     the minimum aggregate amount of additional consideration, if any, payable
     to the Company upon the conversion or exchange thereof, by (y) the total
     maximum number of shares of Common Stock issuable upon the conversion or
     exchange of all such Convertible Securities) shall be less than the
     Purchase Price in effect immediately prior to the time of such issue or
     sale, then the total maximum number of shares of Common Stock issuable upon
     conversion or exchange of all such Convertible Securities shall (as of the
     date of the issue or sale of such Convertible Securities) be deemed to be
     outstanding and to have been issued and sold by the Company for such price

                                       4
<PAGE>
 
     per share. No adjustment of the Purchase Price shall be made upon the
     actual issue of such Common Stock upon exercise of the rights to exchange
     or convert under such Convertible Securities, except as otherwise provided
     in subparagraph (3) below.

          (3)  If the purchase price provided for in any Options referred to in
     subparagraph (1), the additional consideration, if any, payable upon the
     conversion or exchange of any Convertible Securities referred to in
     subparagraphs (1) or (2), or the rate at which any Convertible Securities
     referred to in subparagraph (1) or (2) are convertible into or exchangeable
     for Common Stock shall change at any time (other than under or by reason of
     provisions designed to protect against dilution of the type set forth in
     Paragraph 3.1 or 3.3), the Purchase Price in effect at the time of such
     change shall forthwith be readjusted to the Purchase Price which would have
     been in effect at such time had such Options or Convertible Securities
     still outstanding provided for such changed purchase price, additional
     consideration or conversion rate, as the case may be, at the time initially
     granted, issued or sold. If the purchase price provided for in any Option
     referred to in subparagraph (1) or the rate at which any Convertible
     Securities referred to in subparagraphs (1) or (2) are convertible into or
     exchangeable for Common Stock, shall be reduced at any time under or by
     reason of provisions with respect thereto designed to protect against
     dilution, then in case of the delivery of Common Stock upon the exercise of
     any such Option or upon conversion or exchange of any such Convertible
     Security, the Purchase Price then in effect hereunder shall forthwith be
     adjusted to such respective amount as would have been obtained had such
     Option or Convertible Security never been issued as to such Common Stock
     and had adjustments been made upon the issuance of the shares of Common
     Stock delivered as aforesaid, but only if as a result of such adjustment
     the Purchase Price then in effect hereunder is hereby reduced.

          (4)  On the expiration of any Option or the termination of any right
     to convert or exchange any Convertible Securities, the Purchase Price then
     in effect hereunder shall forthwith be increased to the Purchase Price
     which would have been in effect at the time of such expiration or
     termination had such Option or Convertible Securities, to the extent
     outstanding immediately prior to such expiration or termination, never been
     issued.

          (5)  In case any Options shall be issued in connection with the issue
     or sale of other securities of the Company, together comprising one
     integral transaction in which no specific consideration is allocated to
     such Options by the parties thereto, such Options shall be deemed to have
     been issued without consideration.

          (6)  In case any shares of Common Stock, Options or Convertible
     Securities shall be issued or sold or deemed to have been issued or sold
     for cash, the consideration received therefor shall be deemed to be the
     amount received by the Company therefor. In case any shares of Common
     Stock, Options or Convertible Securities shall be issued or sold for a
     consideration other than cash, the amount of the consideration other than
     cash received by the Company shall be the fair value of such consideration
     as determined in good faith by the

                                       5
<PAGE>
 
     Board of Directors of the Company. In case any shares of Common Stock,
     Options or Convertible Securities shall be issued in connection with any
     merger in which the Company is the surviving corporation, the amount of
     consideration therefor shall be deemed to be the fair value of such portion
     of the net assets and business of the non-surviving corporation as shall be
     attributed by the Board of Directors of the Company in good faith to such
     Common Stock, Options or Convertible Securities, as the case may be.

          (7)  The number of shares of Common Stock outstanding at any given
     time shall not include shares owned or held by or for the account of the
     Company, and the disposition of any shares so owned or held shall be
     considered an issue or sale of Common Stock for the purpose of this
     Paragraph 3.1.

          (8)  In case the Company shall declare a dividend or make any other
     distribution upon the stock of the Company payable in Common Stock,
     Options, or Convertible Securities, then in such case any Common Stock,
     Options or Convertible Securities, as the case may be, issuable in payment
     of such dividend or distribution shall be deemed to have been issued or
     sold without consideration.

          (9)  For purposes of this Paragraph 3.1, in case the Company shall
     take a record of the holders of its Common Stock for the purpose of
     entitling them (x) to receive a dividend or other distribution payable in
     Common Stock, Options or in Convertible Securities, or (y) to subscribe for
     or purchase Common Stock, Options or Convertible Securities, then such
     record date shall be deemed to be the date of the issue or sale of the
     shares of Common Stock deemed to have been issued or sold upon the
     declaration of such dividend or the making of such other distribution or
     the date of the granting of such right or subscription or purchase, as the
     case may be.

          3.2.  Dividends Not Paid Out of Earnings or Earned Surplus.  In the
                ----------------------------------------------------         
event the Company shall declare a dividend upon the Common Stock (other than a
dividend payable in Common Stock covered by subparagraph 3.1(8)) payable
otherwise than out of earnings or earned surplus, determined in accordance with
generally accepted accounting principles, including the making of appropriate
deductions for minority interests, if any, in subsidiaries (herein referred to
as "Liquidating Dividends"), then, as soon as possible after the exercise of
this Warrant, the Company shall pay to the person exercising such Warrant an
amount equal to the aggregate value at the time of such exercise of all
Liquidating Dividends (including but not limited to the Common Stock which would
have been issued at the time of such earlier exercise and all other securities
which would have been issued with respect to such Common Stock by reason of
stock splits, stock dividends, mergers or reorganizations, or for any other
reason).  For the purposes of this Paragraph 3.2, a dividend other than in cash
shall be considered payable out of earnings or earned surplus only to the extent
that such earnings or earned surplus are charged an amount equal to the fair
value of such dividend as determined in good faith by the Board of Directors of
the Company.

          3.3.  Subdivisions and Combinations.  In case the Company shall at any
                -----------------------------                                   
time subdivide (other than by means of a dividend payable in Common Stock
covered by subparagraph 3.1(8)), its outstanding shares of Common Stock into a
greater number of shares, the Purchase Price in effect immediately prior to such
subdivision shall be proportionately reduced, and, conversely, in case the
outstanding shares of Common Stock of the Company shall be combined into a
smaller number of shares, the Purchase Price in effect immediately prior to such
combination shall be proportionately increased.

          3.4.  Reorganization, Reclassification, Consolidation, Merger or Sale
                ---------------------------------------------------------------
of Assets.  If any capital reorganization or reclassification of the capital
- ---------                                                                   
stock of the Company, or consolidation or merger of the Company with another
corporation, or the sale of all or substantially all of its assets to another
corporation shall be effected in such a way that holders of Common Stock shall
be entitled to receive stock, securities, cash or other property with respect to
or in exchange for Common Stock, then, as a condition of such reorganization,
reclassification, consolidation, merger or sale, lawful and adequate provision
shall be made whereby the holder of this Warrant shall have the right to acquire
and receive upon exercise of this Warrant such shares of stock, securities, cash
or other property issuable or payable (as part of the reorganization,
reclassification, consolidation, merger or sale) with respect to or in exchange
for such number of outstanding shares of the Company's Common Stock as would
have been received upon exercise of this Warrant at the Purchase Price then in
effect.  The Company will not effect any such consolidation, merger or sale,
unless prior to the consummation thereof the successor corporation (if other
than the Company) resulting from such consolidation or merger or the corporation
purchasing such assets shall assume by written instrument mailed or delivered to
the holder of this Warrant at the last address of such holder appearing on the
books of the Company, the obligation to deliver to such holder such shares of
stock, securities or assets as, in accordance with the foregoing provisions,
such holder may be entitled to purchase.  If a purchase, tender or exchange
offer is made to and accepted by the holders of more than 50% of the outstanding
shares of Common Stock of the Company, the Company shall not effect any
consolidation, merger or sale with the person having made such offer or with any
Affiliate of such person, unless prior to the consummation of such
consolidation, merger or sale the holder of this Warrant shall have been given a
reasonable opportunity to then elect to receive upon the exercise of this
Warrant either the stock, securities or assets then issuable with respect to the
Common Stock of the Company or the stock, securities or assets, or the
equivalent, issued to previous holders of the Common Stock in accordance with
such offer.  For purposes hereof the term "Affiliate" with respect to any given
person shall mean any person controlling, controlled by or under common control
with the given person.

          3.5.  No Adjustment for Exercise of Certain Options, Warrants, Etc.
                ------------------------------------------------------------  
The provisions of this Section 3 shall not apply to any Common Stock issued,
issuable or deemed outstanding under subparagraphs 3.1(1) to (9) inclusive:  (i)
to any person pursuant to any stock option, stock purchase or similar plan or
arrangement for the benefit of employees, consultants or directors of the
Company or its subsidiaries or (ii) pursuant to options, warrants and conversion
rights in existence on the date of issuance hereof.

                                       7
<PAGE>
 
          3.6.  Notices of Record Date, Etc.  In the event that:
                ---------------------------                     

               (1)  the Company shall declare any cash dividend upon its Common
Stock, or

               (2)  the Company shall declare any dividend upon its Common Stock
payable in stock or make any special dividend or other distribution to the
holders of its Common Stock, or

               (3)  the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or other
rights, or

               (4)  there shall be any capital reorganization or
reclassification of the capital stock of the Company, including any subdivision
or combination of its outstanding shares of Common Stock, or consolidation or
merger of the Company with, or sale of all or substantially all of its assets
to, another corporation, or
    
               (5)  there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company; then, in connection with such event,
the Company shall give to the holder of this Warrant:     

          (i)  at least ten (10) days' prior written notice of the date on which
the books of the Company shall close or a record shall be taken for such
dividend, distribution or subscription rights or for determining rights to vote
in respect of any such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding up; and

          (ii) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding up, at least
ten (10) days' prior written notice of the date when the same shall take place.
Such notice in accordance with the foregoing clause (i) shall also specify, in
the case of any such dividend, distribution or subscription rights, the date on
which the holders of Common Stock shall be entitled thereto, and such notice in
accordance with the foregoing clause (ii) shall also specify the date on which
the holders of Common Stock shall be entitled to exchange their Common Stock for
securities or other property deliverable upon such reorganization,
reclassification consolidation, merger, sale, dissolution, liquidation or
winding up, as the case may be. Each such written notice shall be given by first
class mail, postage prepaid, addressed to the holder of this Warrant at the
address of such holder as shown on the books of the Company.

          3.7. Grant, Issue or Sale of Options, Convertible Securities, or
               -----------------------------------------------------------
Rights.  If at any time or from time to time on or after the date of issuance
- ------                                                                       
hereof, the Company shall grant, issue or sell any Options, Convertible
Securities or rights to purchase property (the "Purchase Rights") pro rata to
the record holders of any class of Common Stock of the Company and such grants,
issuances or sales do not result in an adjustment of the Purchase Price under
Paragraph 3.1 hereof, then the holder of this Warrant shall be entitled to
acquire (within thirty (30) days after the later to occur of the 

                                       8
<PAGE>
 
initial exercise date of such Purchase Rights or receipt by such holder of the
notice concerning Purchase Rights to which such holder shall be entitled under
Paragraph 3.6) and upon the terms applicable to such Purchase Rights either:

          (i)  the aggregate Purchase Rights which such holder could have
acquired if it had held the number of shares of Common Stock acquirable upon
exercise of this Warrant immediately before the grant, issuance or sale of such
Purchase Rights; provided that if any Purchase Rights were distributed to
holders of Common Stock without the payment of additional consideration by such
holders, corresponding Purchase Rights shall be distributed to the exercising
holder of this Warrant as soon as possible after such exercise and it shall not
be necessary for the exercising holder of this Warrant specifically to request
delivery of such rights; or

          (ii) in the event that any such Purchase Rights shall have expired or
shall expire prior to the end of said thirty (30) day period, the number of
shares of Common Stock or the amount of property which such holder could have
acquired upon such exercise at the time or times at which the Company granted,
issued or sold such expired Purchase Rights.

          3.8.  Adjustment by Board of Directors.  If any event occurs as to
                --------------------------------                            
which, in the opinion of the Board of Directors of the Company, the provisions
of this Section 3 are not strictly applicable or if strictly applicable would
not fairly protect the rights of the holder of this Warrant in accordance with
the essential intent and principles of such provisions, then the Board of
Directors shall make an adjustment in the application of such provisions, in
accordance with such essential intent and principles, so as to protect such
rights as aforesaid, but in no event shall any adjustment have the effect of
increasing the Purchase Price as otherwise determined pursuant to any of the
provisions of this Section 3 except in the case of a combination of shares of a
type contemplated in Paragraph 3.3 and then in no event to an amount larger than
the Purchase Price as adjusted pursuant to Paragraph 3.3.

          3.9.  Fractional Shares.  The Company shall not issue fractions of
                -----------------                                           
shares of Common Stock upon exercise of this Warrant or scrip in lieu thereof.
If any fraction of a share of Common Stock would, except for the provisions of
this Paragraph 3.9, be issuable upon exercise of this Warrant, the Company shall
in lieu thereof pay to the person entitled thereto an amount in cash equal to
the current value of such fraction, calculated to the nearest one-hundredth
(1/100) of a share, to be computed (i) if the Common Stock is listed on any
national securities exchange on the basis of the last sales price of the Common
Stock on such exchange (or the quoted closing bid price if there shall have been
no sales) on the date of conversion, or (ii) if the Common Stock shall not be
listed, on the basis of the mean between the closing bid and asked prices for
the Common Stock on the date of conversion as reported by Nasdaq, or its
successor, and if there are not such closing bid and asked prices, on the basis
of the fair market value per share as determined by the Board of Directors of
the Company.

          3.10. Officers' Statement as to Adjustments.  Whenever the Purchase
                -------------------------------------                        
Price shall be adjusted as provided in Section 3 hereof, the Company shall
forthwith file at each office designated 

                                       9
<PAGE>
 
for the exercise of this Warrant, a statement, signed by the Chairman of the
Board, the President, any Vice President or Treasurer of the Company, showing in
reasonable detail the facts requiring such adjustment and the Purchase Price
that will be effective after such adjustment. The Company shall also cause a
notice setting forth any such adjustments to be sent by mail, first class,
postage prepaid, to the record holder of this Warrant at its address appearing
on the stock register. If such notice relates to an adjustment resulting from an
event referred to in Paragraph 3.6, such notice shall be included as part of the
notice required to be mailed and published under the provisions of Paragraph 3.6
hereof.


          4.  NO DILUTION OR IMPAIRMENT.  The Company will not, by amendment of
its charter or through reorganization, consolidation, merger, dissolution, sale
of assets or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such action as may be necessary or appropriate in order to protect the rights of
the holder hereof against dilution or other impairment.  Without limiting the
generality of the foregoing, the Company will not increase the par value of any
shares of stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise, and at all times will take all such action
as may be necessary or appropriate in order that the Company may validly and
legally issue fully paid and non-assessable stock upon the exercise of this
Warrant.

          5.  RESERVATION OF STOCK ISSUABLE ON EXERCISE OF WARRANTS. The Company
shall at all times reserve and keep available out of its authorized but unissued
stock, solely for the issuance and delivery upon the exercise of this Warrant
and other similar Warrants, such number of its duly authorized shares of Common
Stock as from time to time shall be issuable upon the exercise of this Warrant
and all other similar Warrants at the time outstanding.  All of the shares of
Common Stock issuable upon exercise of this Warrant, when issued and delivered
in accordance with the terms hereof, will be duly authorized, validly issued,
fully-paid and non-assessable.

          6.  REPLACEMENT OF WARRANT.  Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and (in the case of loss, theft or destruction) upon delivery of an
indemnity agreement (with surety if reasonably required) in an amount reasonably
satisfactory to it, or (in the case of mutilation) upon surrender and
cancellation thereof, the Company will issue, in lieu thereof, a new Warrant of
like tenor.

          7.  REMEDIES.  The Company stipulates that the remedies at law of the
holder of this Warrant in the event of any default by the Company in the
performance of or compliance with any of the terms of this Warrant are not and
will not be adequate, and that the same may be specifically enforced.

          8.  REGISTRATION RIGHTS.  All of the provisions of Article V -
"Registration Rights" in the Preferred Stock Purchase Agreement dated as of

                                      10

issuable upon exercise of this Warrant and any similar Warrants and each
reference in the Series A Purchase Agreement to "Registrable Shares" shall mean
the Registrable Shares as defined in that agreement and the shares issuable upon
exercise of this Warrant and any similar Warrants, collectively as a single
class.

          9.  NEGOTIABILITY.  This Warrant is issued upon the following terms,
to all of which each taker or owner hereof consents and agrees:

          (a) Subject to the legend appearing on the first page hereof, title to
this Warrant may be transferred by endorsement (by the holder hereof executing
the form of assignment at the end hereof including guaranty of signature) and
delivery in the same manner as in the case of a negotiable instrument
transferable by endorsement and delivery. Absent an effective registration
statement under the Securities Act of 1933, as amended (the "Act"), covering the
disposition of this Warrant or the shares of Common Stock issued or issuable
upon exercise hereof, the holder will not sell or transfer any or all of such
Warrant or shares, as the case may be, without first providing the Company with
an opinion of counsel (which may be counsel for the Company) to the effect that
such sale or transfer will be exempt from the registration and prospectus
delivery requirements of the Act. Each certificate representing shares of Common
Stock issued pursuant to this Warrant, unless at the same time of exercise such
Warrant Shares are registered under the Act, shall bear a legend in
substantially the following form on the face thereof:

          THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933 OR APPLICABLE STATE SECURITIES LAWS AND MAY BE TRANSFERRED OR
          RESOLD ONLY IN COMPLIANCE WITH SUCH SECURITIES LAWS.

Any certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a certificate issued upon completion of
a distribution under a registration statement covering the securities
represented shall also bear such legend unless, in the opinion of counsel to the
Company, the securities represented thereby may be transferred as contemplated
by such holder without violation of the registration requirements of the Act.

          (b) Any person in possession of this Warrant properly endorsed is
authorized to represent itself as absolute owner hereof and is granted power to
transfer absolute title hereto by endorsement and delivery hereof to a bona fide
purchaser hereof for value; each prior taker or owner waives and renounces all
of its equities or rights in this Warrant in favor of every such bona fide
purchaser, and every such bona fide purchaser shall acquire title hereto and to
all rights represented hereby.

          (c) Until this Warrant is transferred on the books of the Company, the
Company may treat the registered holder of this Warrant as the absolute owner
hereof for all purposes without being affected by any notice to the contrary.

                                      11

          (d) Prior to the exercise of this Warrant, the holder hereof shall not
be entitled to any rights of a shareholder of the Company with respect to shares
for which this Warrant shall be exercisable, including, without limitation, the
right to vote, to receive dividends or other distributions or to exercise any
preemptive rights, and shall not be entitled to receive any notice of any
proceedings of the Company, except as provided herein.

          (e) The Company shall not be required to pay any Federal or state
transfer tax or charge that may be payable in respect of any transfer involved
in the transfer or delivery of this Warrant or the issuance or conversion or
delivery of certificates for Common Stock in a name other than that of the
registered holder of this Warrant or to issue or deliver any certificates for
Common Stock upon the exercise of this Warrant until any and all such taxes and
charges shall have been paid by the holder of this Warrant or until it has been
established to the Company's satisfaction that no such tax or charge is due.

THIS WARRANT AND THE SECURITIES ISSUABLE UPON ITS EXERCISE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT
BE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION UNDER THE ACT OR IN
A TRANSACTION WHICH QUALIFIES AS AN EXEMPT TRANSACTION UNDER THE ACT AND THE

DATE: NOVEMBER 25, 1998                                   WARRANT TO PURCHASE
                                                            _______ SHARES OF
COMMON STOCK


                               VERTICALNET, INC.

                         COMMON STOCK PURCHASE WARRANT


     VerticalNet, Inc., a Pennsylvania corporation (the "Company"), hereby
certifies that, for value received, _________________ (the "holder"), or
assigns, is entitled, subject to the terms set forth below, to purchase from the
Company, at any time and from time to time during the period beginning on the
earlier of (a) the effective date of the registration statement for an
underwritten public offering of the Company's common stock, par value $.01 per
share, (b) the closing date of the next round of equity financing in the Company
raising not less than $5,000,000 from third party investors other than holder
(the "Next Round Financing") and (c) May 31, 1999, and ending on November 24,
2008, an aggregate of _____________ (____) fully paid and non-assessable shares
of the common stock, par value $.01 per share, of the Company at the "Purchase
Price" (as hereinafter defined), subject to the provisions of Paragraph 3
hereof.  "Purchase Price" shall mean (x) if either of the transactions specified
in clauses (a) and (b) above occur before May 31, 1999, the price per share paid
for shares of common stock, par value $.01 per share, of the Company in such
transaction (before underwriting discounts and commissions) or (y) if neither of
the events specified in clauses (a) and (b) above occur before May 31, 1999,
$1.80 per share. "Common Stock" shall mean, unless the context otherwise
requires, the stock or other securities or property at the time deliverable upon
the exercise of this Warrant. Notwithstanding the foregoing, the Purchase Price
and the number and character of shares issuable under this Warrant are subject
to adjustment as set forth in Paragraph 3. This Warrant is herein called the
"Warrant."

     1.   EXERCISE OF WARRANT.  The purchase rights evidenced by this Warrant
shall be exercised by the holder hereof surrendering this Warrant, with the form
of subscription at the end hereof duly executed by such holder, to the Company
at its office at Two Walnut Grove Drive, Suite 150, Horsham, Pennsylvania 19044,
or such other address as the Company may specify by written notice to the
registered holder hereof, accompanied by payment, in cash, by certified or
official bank check or by wire transfer of an amount equal to the Purchase Price
multiplied by the number of shares being purchased pursuant to such exercise of
the Warrant.
<PAGE>
 
          1.1  Partial Exercise.  This Warrant may be exercised for less than
               ----------------                                              
the full number of shares of Common Stock, in which case the number of shares
receivable upon the exercise of this Warrant as a whole, and the sum payable
upon the exercise of this Warrant as a whole, shall be proportionately reduced.
Upon any such partial exercise, the Company at its expense will forthwith issue
to the holder hereof a new Warrant or Warrants of like tenor calling for the
number of shares of Common Stock as to which rights have not been exercised,
such Warrant or Warrants to be issued in the name of the holder hereof or his
nominee (upon payment by such holder of any applicable transfer taxes).
 
          1.2. Net Issue Exercise.
               ------------------ 

               (1) In lieu of exercising this Warrant, holder may elect to
receive shares equal to the value of this Warrant (or the portion thereof being
canceled) by surrender of this Warrant at the principal office of the Company
together with notice of such election in which event the Company shall issue to
holder that number of shares of the Company's Common Stock computed using the
following formula:

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

          X =  the number of shares of Common Stock to be issued to Holder.

          Y =  the number of shares of Common Stock purchasable under
               this Warrant

          A =  the fair market value of one share of the Company's Common Stock.

          B =  the Purchase Price (as adjusted to the date of such
calculations).

               (2) For purposes of this Section, the fair market value of one
share of the Company's Common Stock shall be based on the average of the closing
bid and asked prices of the Summary or the closing price quoted in the Over-The-
Counter Market Summary or the closing price quoted on any exchange on which the
Common Stock is listed, whichever is applicable, as published in the Eastern
Edition of The Wall Street Journal for the ten trading days prior to the date of
determination of fair market value. If the Common Stock is not traded Over-The-
Counter or on an exchange, the fair market value of the Company's Common Stock
shall be the price per share which the Company could obtain from a willing buyer
for shares sold by the Company from authorized but unissued shares, as such
price shall be agreed by the Company and the holder.

     2.   DELIVERY OF STOCK CERTIFICATES ON EXERCISE.  As soon as practicable
after the exercise of this Warrant and payment of the Purchase Price, and in any
event within ten (10) days thereafter, the Company, at its expense, will cause
to be issued in the name 

                                       2
<PAGE>
 
of and delivered to the holder hereof a certificate or certificates for the
number of fully paid and non-assessable shares or other securities or property
to which such holder shall be entitled upon such exercise, plus, in lieu of any
fractional share to which such holder would otherwise be entitled, cash in an
amount determined in accordance with Paragraph 3.9 hereof. The Company agrees
that the shares so purchased shall be deemed to be issued to the holder hereof
as the record owner of such shares as of the close of business on the date on
which this Warrant shall have been surrendered and payment made for such shares
as aforesaid.

     3.   ANTI-DILUTION PROVISIONS AND OTHER ADJUSTMENTS.  In order to prevent
dilution of the right granted hereunder, the Purchase Price shall be subject to
adjustment from time to time in accordance with this Paragraph 3.  Upon each
adjustment of the Purchase Price pursuant to this Paragraph 3, the  registered
Holder of this Warrant shall thereafter be entitled to acquire upon exercise, at
the Purchase Price resulting from such adjustment, the number of shares of the
Company's Common Stock obtainable by multiplying the Purchase Price in effect
immediately prior to such adjustment by the number of shares of the Company's
Common Stock acquirable immediately prior to such adjustment and dividing the
product thereof by the Purchase Price resulting from such adjustment.

          3.1. Adjustment for Issue or Sale of Common Stock at Less than
               ---------------------------------------------------------
Purchase Price.  Except as provided in Paragraph 3.2 or 3.5 below, if and
- --------------                                                           
whenever on or after the date of issuance hereof the Company shall issue or
sell, or shall in accordance with subparagraphs 3.1(1) to (9), inclusive, be
deemed to have issued or sold, any shares of its Common Stock for a
consideration per share less than the Purchase Price in effect immediately prior
to the time of such issue or sale, then forthwith upon such issue or sale (the
"Triggering Transaction"), the Purchase Price shall, subject to subparagraphs
(1) to (9) of this Paragraph 3.1, be reduced to the Purchase Price (calculated
to the nearest tenth of a cent) determined by dividing:

               (i)   an amount equal to the sum of (x) the product derived by
multiplying the Number of Common Shares Deemed Outstanding immediately prior to
such Triggering Transaction by the Purchase Price then in effect, plus (y) the
consideration, if any, received by the Company upon consummation of such
Triggering Transaction, by

               (ii)  an amount equal to the sum of (x) the Number of Common
     Shares Deemed Outstanding immediately prior to such Triggering Transaction
     plus (y) the number of shares of Common Stock issued (or deemed to be
     issued in accordance with subparagraphs 3.1(1) to (9)) in connection with
     the Triggering Transaction.

          For purposes of this Paragraph 3, the term "Number of Common Shares
     Deemed Outstanding" at any given time shall mean the sum of (i) the number
     of shares of the Company's Common Stock outstanding at such time, and (ii)
     the number of shares of the Company's Common Stock deemed to be outstanding
     under subparagraphs 3.1(1) to (9), inclusive, at such time.

                                       3
<PAGE>
 
          For purposes of determining the adjusted Purchase Price under this
Paragraph 3.1, the following subsections (1) to (9), inclusive, shall be
applicable:

          (1) In case the Company at any time shall in any manner grant (whether
     directly or by assumption in a merger or otherwise) any rights to subscribe
     for or to purchase, or any options for the purchase of, Common Stock or any
     stock or other securities convertible into or exchangeable for Common Stock
     (such rights or options being herein called "Options" and such convertible
     or exchangeable stock or securities being herein called "Convertible
     Securities"), whether or not such Options or the right to convert or
     exchange any such Convertible Securities are immediately exercisable and
     the price per share for which the Common Stock is issuable upon exercise,
     conversion or exchange (determined by dividing (x) the total amount, if
     any, received or receivable by the Company as consideration for the
     granting of such Options, plus the minimum aggregate amount of additional
     consideration payable to the Company upon the exercise of all such Options,
     plus, in the case of such Options which relate to Convertible Securities,
     the minimum aggregate amount of additional consideration, if any, payable
     upon the issue or sale of such Convertible Securities and upon the
     conversion or exchange thereof, by (y) the total maximum number of shares
     of Common Stock issuable upon the exercise of such Options or the
     conversion or exchange of such Convertible Securities) shall be less than
     the Purchase Price in effect immediately prior to the time of the granting
     of such Option, then the total maximum amount of Common Stock issuable upon
     the exercise of such Options, or, in the case of Options for Convertible
     Securities, upon the conversion or exchange of such Convertible Securities,
     shall (as of the date of granting of such Options) be deemed to be
     outstanding and to have been issued and sold by the Company for such price
     per share. No adjustment of the Purchase Price shall be made upon the
     actual issue of such shares of Common Stock or such Convertible Securities
     upon the exercise of such Options, except as otherwise provided in
     subparagraph (3) below.

          (2) In case the Company at any time shall in any manner issue (whether
     directly or by assumption in a merger or otherwise) or sell any Convertible
     Securities, whether or not the rights to exchange or convert thereunder are
     immediately exercisable, and the price per share for which Common Stock is
     issuable upon such conversion or exchange (determined by dividing (x) the
     total amount received or receivable by the Company as consideration for the
     issue or sale of such Convertible Securities, plus the minimum aggregate
     amount of additional consideration, if any, payable to the Company upon the
     conversion or exchange thereof, by (y) the total maximum number of shares
     of Common Stock issuable upon the conversion or exchange of all such
     Convertible Securities) shall be less than the Purchase Price in effect
     immediately prior to the time of such issue or sale, then the total maximum
     number of shares of Common Stock issuable upon conversion or exchange of
     all such Convertible Securities shall (as of the date of the issue or sale
     of such Convertible Securities) be deemed to be outstanding and to have
     been issued and sold by the Company for such price per share. No adjustment
     of the Purchase Price shall be made upon the actual issue of such Common
     Stock upon exercise 

                                       4
<PAGE>
 
     of the rights to exchange or convert under such Convertible Securities,
     except as otherwise provided in subparagraph (3) below.

          (3) If the purchase price provided for in any Options referred to in
     subparagraph (1), the additional consideration, if any, payable upon the
     conversion or exchange of any Convertible Securities referred to in
     subparagraphs (1) or (2), or the rate at which any Convertible Securities
     referred to in subparagraph (1) or (2) are convertible into or exchangeable
     for Common Stock shall change at any time (other than under or by reason of
     provisions designed to protect against dilution of the type set forth in
     Paragraph 3.1 or 3.3), the Purchase Price in effect at the time of such
     change shall forthwith be readjusted to the Purchase Price which would have
     been in effect at such time had such Options or Convertible Securities
     still outstanding provided for such changed purchase price, additional
     consideration or conversion rate, as the case may be, at the time initially
     granted, issued or sold. If the purchase price provided for in any Option
     referred to in subparagraph (1) or the rate at which any Convertible
     Securities referred to in subparagraphs (1) or (2) are convertible into or
     exchangeable for Common Stock, shall be reduced at any time under or by
     reason of provisions with respect thereto designed to protect against
     dilution, then in case of the delivery of Common Stock upon the exercise of
     any such Option or upon conversion or exchange of any such Convertible
     Security, the Purchase Price then in effect hereunder shall forthwith be
     adjusted to such respective amount as would have been obtained had such
     Option or Convertible Security never been issued as to such Common Stock
     and had adjustments been made upon the issuance of the shares of Common
     Stock delivered as aforesaid, but only if as a result of such adjustment
     the Purchase Price then in effect hereunder is hereby reduced.

          (4) On the expiration of any Option or the termination of any right to
     convert or exchange any Convertible Securities, the Purchase Price then in
     effect hereunder shall forthwith be increased to the Purchase Price which
     would have been in effect at the time of such expiration or termination had
     such Option or Convertible Securities, to the extent outstanding
     immediately prior to such expiration or termination, never been issued.

          (5) In case any Options shall be issued in connection with the issue
     or sale of other securities of the Company, together comprising one
     integral transaction in which no specific consideration is allocated to
     such Options by the parties thereto, such Options shall be deemed to have
     been issued without consideration.

          (6) In case any shares of Common Stock, Options or Convertible
     Securities shall be issued or sold or deemed to have been issued or sold
     for cash, the consideration received therefor shall be deemed to be the
     amount received by the Company therefor. In case any shares of Common
     Stock, Options or Convertible Securities shall be issued or sold for a
     consideration other than cash, the amount of the consideration other than
     cash received by the Company shall be the fair value of such consideration
     as determined in good faith by the Board of Directors of the Company. In
     case any shares of Common Stock, Options or Convertible Securities shall be
     issued in connection with any merger in 

                                       5
<PAGE>
 
     which the Company is the surviving corporation, the amount of consideration
     therefor shall be deemed to be the fair value of such portion of the net
     assets and business of the non-surviving corporation as shall be attributed
     by the Board of Directors of the Company in good faith to such Common
     Stock, Options or Convertible Securities, as the case may be.

          (7)  The number of shares of Common Stock outstanding at any given
     time shall not include shares owned or held by or for the account of the
     Company, and the disposition of any shares so owned or held shall be
     considered an issue or sale of Common Stock for the purpose of this
     Paragraph 3.1.

          (8)  In case the Company shall declare a dividend or make any other
     distribution upon the stock of the Company payable in Common Stock,
     Options, or Convertible Securities, then in such case any Common Stock,
     Options or Convertible Securities, as the case may be, issuable in payment
     of such dividend or distribution shall be deemed to have been issued or
     sold without consideration.

          (9)  For purposes of this Paragraph 3.1, in case the Company shall
     take a record of the holders of its Common Stock for the purpose of
     entitling them (x) to receive a dividend or other distribution payable in
     Common Stock, Options or in Convertible Securities, or (y) to subscribe for
     or purchase Common Stock, Options or Convertible Securities, then such
     record date shall be deemed to be the date of the issue or sale of the
     shares of Common Stock deemed to have been issued or sold upon the
     declaration of such dividend or the making of such other distribution or
     the date of the granting of such right or subscription or purchase, as the
     case may be.

          3.2. Dividends Not Paid Out of Earnings or Earned Surplus.  In the
               ----------------------------------------------------         
event the Company shall declare a dividend upon the Common Stock (other than a
dividend payable in Common Stock covered by subparagraph 3.1(8)) payable
otherwise than out of earnings or earned surplus, determined in accordance with
generally accepted accounting principles, including the making of appropriate
deductions for minority interests, if any, in subsidiaries (herein referred to
as "Liquidating Dividends"), then, as soon as possible after the exercise of
this Warrant, the Company shall pay to the person exercising such Warrant an
amount equal to the aggregate value at the time of such exercise of all
Liquidating Dividends (including but not limited to the Common Stock which would
have been issued at the time of such earlier exercise and all other securities
which would have been issued with respect to such Common Stock by reason of
stock splits, stock dividends, mergers or reorganizations, or for any other
reason).  For the purposes of this Paragraph 3.2, a dividend other than in cash
shall be considered payable out of earnings or earned surplus only to the extent
that such earnings or earned surplus are charged an amount equal to the fair
value of such dividend as determined in good faith by the Board of Directors of
the Company.

          3.3. Subdivisions and Combinations.  In case the Company shall at any
               -----------------------------                                   
time subdivide (other than by means of a dividend payable in Common Stock
covered by 

                                       6
<PAGE>
 
subparagraph 3.1(8)), its outstanding shares of Common Stock into a greater
number of shares, the Purchase Price in effect immediately prior to such
subdivision shall be proportionately reduced, and, conversely, in case the
outstanding shares of Common Stock of the Company shall be combined into a
smaller number of shares, the Purchase Price in effect immediately prior to such
combination shall be proportionately increased.

          3.4. Reorganization, Reclassification, Consolidation, Merger or Sale
               ---------------------------------------------------------------
of Assets. If any capital reorganization or reclassification of the capital
- ---------                                                                  
stock of the Company, or consolidation or merger of the Company with another
corporation, or the sale of all or substantially all of its assets to another
corporation shall be effected in such a way that holders of Common Stock shall
be entitled to receive stock, securities, cash or other property with respect to
or in exchange for Common Stock, then, as a condition of such reorganization,
reclassification, consolidation, merger or sale, lawful and adequate provision
shall be made whereby the holder of this Warrant shall have the right to acquire
and receive upon exercise of this Warrant such shares of stock, securities, cash
or other property issuable or payable (as part of the reorganization,
reclassification, consolidation, merger or sale) with respect to or in exchange
for such number of outstanding shares of the Company's Common Stock as would
have been received upon exercise of this Warrant at the Purchase Price then in
effect.  The Company will not effect any such consolidation, merger or sale,
unless prior to the consummation thereof the successor corporation (if other
than the Company) resulting from such consolidation or merger or the corporation
purchasing such assets shall assume by written instrument mailed or delivered to
the holder of this Warrant at the last address of such holder appearing on the
books of the Company, the obligation to deliver to such holder such shares of
stock, securities or assets as, in accordance with the foregoing provisions,
such holder may be entitled to purchase.  If a purchase, tender or exchange
offer is made to and accepted by the holders of more than 50% of the outstanding
shares of Common Stock of the Company, the Company shall not effect any
consolidation, merger or sale with the person having made such offer or with any
Affiliate of such person, unless prior to the consummation of such
consolidation, merger or sale the holder of this Warrant shall have been given a
reasonable opportunity to then elect to receive upon the exercise of this
Warrant either the stock, securities or assets then issuable with respect to the
Common Stock of the Company or the stock, securities or assets, or the
equivalent, issued to previous holders of the Common Stock in accordance with
such offer.  For purposes hereof the term "Affiliate" with respect to any given
person shall mean any person controlling, controlled by or under common control
with the given person.

          3.5. No Adjustment for Exercise of Certain Options, Warrants, Etc.
               ------------------------------------------------------------  
The provisions of this Section 3 shall not apply to any Common Stock issued,
issuable or deemed outstanding under subparagraphs 3.1(1) to (9) inclusive:  (i)
to any person pursuant to any stock option, stock purchase or similar plan or
arrangement for the benefit of employees, consultants or directors of the
Company or its subsidiaries or (ii) pursuant to options, warrants and conversion
rights in existence on the date of issuance hereof.

          3.6. Notices of Record Date, Etc.  In the event that:

               (1) the Company shall declare any cash dividend upon its Common
     Stock, or

               (2) the Company shall declare any dividend upon its Common Stock
     payable in stock or make any special dividend or other distribution to the
     holders of its Common Stock, or

               (3) the Company shall offer for subscription pro rata to the
     holders of its Common Stock any additional shares of stock of any class or
     other rights, or

               (4) there shall be any capital reorganization or reclassification
     of the capital stock of the Company, including any subdivision or
     combination of its outstanding shares of Common Stock, or consolidation or
     merger of the Company with, or sale of all or substantially all of its
     assets to, another corporation, or

               (5) there shall be a voluntary or involuntary dissolution,
     liquidation or winding up of the Company;

then, in connection with such event, the Company shall give to the holder of
this Warrant:

          (i)  at least ten (10) days' prior written notice of the date on which
     the books of the Company shall close or a record shall be taken for such
     dividend, distribution or subscription rights or for determining rights to
     vote in respect of any such reorganization, reclassification,
     consolidation, merger, sale, dissolution, liquidation or winding up; and

          (ii) in the case of any such reorganization, reclassification,
     consolidation, merger, sale, dissolution, liquidation or winding up, at
     least ten (10) days' prior written notice of the date when the same shall
     take place.  Such notice in accordance with the foregoing clause (i) shall
     also specify, in the case of any such dividend, distribution or
     subscription rights, the date on which the holders of Common Stock shall be
     entitled thereto, and such notice in accordance with the foregoing clause
     (ii) shall also specify the date on which the holders of Common Stock shall
     be entitled to exchange their Common Stock for securities or other property
     deliverable upon such reorganization, reclassification consolidation,
     merger, sale, dissolution, liquidation or winding up, as the case may be.
     Each such written notice shall be given by first class mail, postage
     prepaid, addressed to the holder of this Warrant at the address of such
     holder as shown on the books of the Company.

          3.7. Grant, Issue or Sale of Options, Convertible Securities, or
               -----------------------------------------------------------
Rights.  If at any time or from time to time on or after the date of issuance
- ------                                                                       
hereof, the Company shall grant, issue or sell any Options, Convertible
Securities or rights to purchase property (the "Purchase Rights") pro rata to
the record holders of any class of Common Stock of the Company and such grants,
issuances or sales do not result in an adjustment of the Purchase Price under
Paragraph 3.1 hereof, then the holder of this Warrant shall be entitled to
acquire (within thirty (30) days 

                                       8

receipt by such holder of the notice concerning Purchase Rights to which such
holder shall be entitled under Paragraph 3.6) and upon the terms applicable to
such Purchase Rights either:

               (i)  the aggregate Purchase Rights which such holder could have
     acquired if it had held the number of shares of Common Stock acquirable
     upon exercise of this Warrant immediately before the grant, issuance or
     sale of such Purchase Rights; provided that if any Purchase Rights were
     distributed to holders of Common Stock without the payment of additional
     consideration by such holders, corresponding Purchase Rights shall be
     distributed to the exercising holder of this Warrant as soon as possible
     after such exercise and it shall not be necessary for the exercising holder
     of this Warrant specifically to request delivery of such rights; or

               (ii) in the event that any such Purchase Rights shall have
     expired or shall expire prior to the end of said thirty (30) day period,
     the number of shares of Common Stock or the amount of property which such
     holder could have acquired upon such exercise at the time or times at which
     the Company granted, issued or sold such expired Purchase Rights.

          3.8. Adjustment by Board of Directors.  If any event occurs as to
               --------------------------------                            
which, in the opinion of the Board of Directors of the Company, the provisions
of this Section 3 are not strictly applicable or if strictly applicable would
not fairly protect the rights of the holder of this Warrant in accordance with
the essential intent and principles of such provisions, then the Board of
Directors shall make an adjustment in the application of such provisions, in
accordance with such essential intent and principles, so as to protect such
rights as aforesaid, but in no event shall any adjustment have the effect of
increasing the Purchase Price as otherwise determined pursuant to any of the
provisions of this Section 3 except in the case of a combination of shares of a
type contemplated in Paragraph 3.3 and then in no event to an amount larger than
the Purchase Price as adjusted pursuant to Paragraph 3.3.

          3.9. Fractional Shares.  The Company shall not issue fractions of
               -----------------                                           
shares of Common Stock upon exercise of this Warrant or scrip in lieu thereof.
If any fraction of a share of Common Stock would, except for the provisions of
this Paragraph 3.9, be issuable upon exercise of this Warrant, the Company shall
in lieu thereof pay to the person entitled thereto an amount in cash equal to
the current value of such fraction, calculated to the nearest one-hundredth
(1/100) of a share, to be computed (i) if the Common Stock is listed on any
national securities exchange on the basis of the last sales price of the Common
Stock on such exchange (or the quoted closing bid price if there shall have been
no sales) on the date of conversion, or (ii) if the Common Stock shall not be
listed, on the basis of the mean between the closing bid and asked prices for
the Common Stock on the date of conversion as reported by Nasdaq, or its
successor, and if there are not such closing bid and asked prices, on the basis
of the fair market value per share as determined by the Board of Directors of
the Company.

Purchase Price shall be adjusted as provided in Section 3 hereof, the Company
shall forthwith file at each office designated for the exercise of this Warrant,
a statement, signed by the Chairman of the Board, the President, any Vice
President or Treasurer of the Company, showing in reasonable detail the facts
requiring such adjustment and the Purchase Price that will be effective after
such adjustment.  The Company shall also cause a notice setting forth any such
adjustments to be sent by mail, first class, postage prepaid, to the record
holder of this Warrant at its address appearing on the stock register.  If such
notice relates to an adjustment resulting from an event referred to in Paragraph
3.6, such notice shall be included as part of the notice required to be mailed
and published under the provisions of Paragraph 3.6 hereof.

     4.   NO DILUTION OR IMPAIRMENT.  The Company will not, by amendment of its
charter or through reorganization, consolidation, merger, dissolution, sale of
assets or any other voluntary action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of the
holder hereof against dilution or other impairment.  Without limiting the
generality of the foregoing, the Company will not increase the par value of any
shares of stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise, and at all times will take all such action
as may be necessary or appropriate in order that the Company may validly and
legally issue fully paid and non-assessable stock upon the exercise of this
Warrant.

     5.   RESERVATION OF STOCK ISSUABLE ON EXERCISE OF WARRANTS.  The Company

satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and (in the case of loss, theft or destruction) upon delivery of an
indemnity agreement (with surety if reasonably required) in an amount reasonably
satisfactory to it, or (in the case of mutilation) upon surrender and
cancellation thereof, the Company will issue, in lieu thereof, a new Warrant of
like tenor.

     7.   REMEDIES.  The Company stipulates that the remedies at law of the
holder of this Warrant in the event of any default by the Company in the
performance of or compliance with any of the terms of this Warrant are not and
will not be adequate, and that the same may be specifically enforced.

     "ACT"). THE SECURITIES REPRESENTED HEREBY MAY NOT BE SOLD,

                               CONVERTIBLE NOTE
                              (VERTICALNET, INC.)

$____________                                            November 25, 1998


     In consideration of the loan (hereinafter referred to as a "Loan")
______________, a ______________ (the "Lender"), has made to VerticalNet, Inc.,
a Pennsylvania corporation (the "Borrower"), and for value received, the
Borrower hereby promises to pay to the order of the Lender, at the Lender's
office located at ________________, or at such other place in the continental
United States as the Lender may designate in writing, in lawful money of the
United States, and in immediately available funds, the principal sum of
_________Dollars ($________).

     1.   Maturity Date.  The unpaid principal balance of this Convertible Note
          -------------                                                        
(this "Note") shall be paid on the earlier of (i) May 31, 1999 (the "Due Date"),
(ii) the closing of the next round of equity financing in the Borrower raising
not less than $5,000,000 from third party investors other than the Lender (the
"Next Round Financing") and (iii) the effective date of the registration
statement for an underwritten public offering of Borrower's Common Stock (as
defined below)(the "IPO").

     2.   Interest.  The Borrower hereby further promises to pay to the order of
          --------                                                              
the Lender interest on the outstanding principal amount from the date hereof, at
an annual rate equal to the announced prime rate of pnc Bank, N.A. (the "Prime
Rate"). Such interest rate shall be changed when and as the Prime Rate changes.
In addition, the Borrower shall pay on demand interest on any overdue payment of
principal and interest (to the extent legally enforceable) at the fluctuating
Prime Rate plus three percent (3%).

     Interest shall be payable when the unpaid principal balance of the Note is
paid.

     All payments made on this Note shall be applied, at the option of the
Lender, first to late charges and collection costs, if any, then to accrued
interest and then to principal. Interest
<PAGE>
 
payable hereunder shall be calculated for actual days elapsed on the basis of a
360-day year. Accrued and unpaid interest shall be due and payable upon maturity
of this Note. After maturity or in the event of default, interest shall continue
to accrue on the Note at the rate set forth above and shall be payable on demand
of the Lender.

     Notwithstanding anything in this Note, the interest rate charged hereon
shall not exceed the maximum rate allowable by applicable law. If any stated
interest rate herein exceeds the maximum allowable rate, then the interest rate
shall be reduced to the maximum allowable rate, and any excess payment of
interest made by the Borrower at any time shall be applied to the unpaid balance
of any outstanding principal of this Note.

     3.   Conversion.  Subject to and in compliance with the provisions of this
          ----------                                                           
Section 3, prior to the payment of the outstanding principal amount of this
Note, the Lender may, convert the outstanding principal amount of this Note, in
whole or in part, into fully paid nonassessable shares of the Borrower's Common
Stock, par value $.01 per share (the "Common Stock"), at the Conversion Price in
effect on the date of conversion.

     The Lender shall only be entitled to convert this Note into Common Stock
one time, upon the earliest of the following events to occur. The Lender shall
only have the right to convert this Note pursuant to clause (iii) below, if
neither the IPO or the Next Round Financing has occurred.

     (i)  If, prior to the Due Date, the Borrower files a registration statement
for an IPO, the Borrower shall, within five business days of the initial filing
of such registration statement, send written notice to the Lender of such filing
(the "Filing Notice"). The Lender shall, within 30 days from the date of receipt
of the Filing Notice (but in any event no later than the printing of the red
herring prospectus for the IPO), determine whether or not it will convert the
outstanding principal amount of this Note, in whole or in part, into Common
Stock in accordance with this Section 3 and send written notice to the Borrower
of such election. If, upon the expiration of such 30-day period, the Lender has
not elected to convert this Note into Common Stock or has not notified the
Borrower of its election, the Lender shall forfeit its right to convert this
Note into Common Stock. If the Lender has elected to convert this Note into
Common Stock pursuant to this paragraph (i), the conversion shall become
effective immediately prior to the effectiveness of the registration statement
for the IPO.

     (ii) If, prior to the Due Date, the Borrower has scheduled the closing of
the Next Round of Financing, at least 20 days prior to the closing of the Next
Round of Financing, the Borrower shall send written notice to the Lender of such
closing (the "Closing Notice"). The Lender shall, within 20 days from the date
of receipt of the Closing Notice, determine whether or not it will convert the
outstanding principal amount of this Note, in whole or in part, into Common
Stock in accordance with this Section 3 and send written notice to the Borrower
of such election. If, upon the expiration of such 20-day period, the Lender has
not elected to convert this Note into Common Stock or has not notified the
Borrower of its election, the Lender shall forfeit its right to convert this
Note into Common Stock. If the Lender has elected to convert this Note

                                       2
<PAGE>
 
into Common Stock pursuant to this paragraph (ii), the conversion shall become
effective immediately prior to the closing of the Next Round of Financing.
 
     (iii)  If the IPO or the Next Round Financing has not occurred prior to the
Due Date, the Lender shall have the right convert the outstanding principal
amount of this Note, in whole or in part, into Common Stock in accordance with
this Section 3 by giving written notice to the Borrower at least two days prior
to the Due Date of its intention to convert this Note into Common Stock.

     The "Conversion Price" at which Common Stock shall be issuable upon
conversion of this Note shall equal either (i) the price per share of the Common
Stock in the IPO, (ii) the price per share of Common Stock in the Next Round of
Financing or (iii) if either the IPO or Next Round Financing does not occur
prior to the Due Date, $1.80, whichever is applicable; provided, however, that
                                                       --------  -------      
the Conversion Price shall be subject to adjustment as follows:

          (a)    In the event the Borrower should at any time or from time to
     time after the date hereof fix a record date for the effectuation of a
     split or subdivision of the outstanding shares of Common Stock or the
     determination of holders of Common Stock entitled to receive a dividend or
     other distribution payable in additional shares of Common Stock or other
     securities or rights convertible into, or entitling the holder thereof to
     receive directly or indirectly, additional shares of Common Stock
     (hereinafter referred to as "Common Stock Equivalents") without payment of
     any consideration by such holder for the additional shares of Common Stock
     or the Common Stock Equivalents (including the additional shares of Common
     Stock issuable upon conversion or exercise thereof), then, as of such
     record date (or the date of such dividend distribution, split or
     subdivision if no record date is fixed), the Conversion Price shall be
     appropriately decreased so that the number of shares of Common Stock
     issuable on conversion of each share of such series shall be increased in
     proportion to such increase of outstanding shares determined in accordance
     with paragraph 4(c).

          (b)    If the number of shares of Common Stock outstanding at any time
     after the date hereof is decreased by a combination of the outstanding
     shares of Common Stock, then following the record date of such combination,
     the Conversion Price shall be appropriately increased so that the number of
     shares of Common Stock issuable on conversion of this Note shall be
     decreased in proportion to such decrease in outstanding shares.

          (c)    In the event of any change in the number of shares of Common
     Stock deliverable or any increase in the consideration payable to the
     Borrower upon exercise of such options or rights or upon conversion of or
     in exchange for such convertible or exchangeable securities, including, but
     not limited to, a change resulting from the anti-dilution provisions
     thereof, the Conversion Price obtained with respect to the adjustment which
     was made upon the issuance of such options, rights or securities, and any

                                       3
<PAGE>
 
     subsequent adjustments based thereon, shall be recomputed to reflect such
     change, but no further adjustment shall be made for the actual issuance of
     Common Stock or any payment of such consideration upon the exercise of any
     such options or rights or the conversion or exchange of such securities.

     To exercise the conversion privilege, the Lender shall surrender this Note,
together with a written conversion notice to the Borrower at its principal
office. This Note or portion thereof shall be deemed to have been converted
immediately prior to the close of business on the date of receipt of such Note
and notice by the Borrower, even if the Borrower's stock transfer books are on
that date closed, and the Lender, or the nominee or nominees of such Lender,
shall be treated for all purposes as the record holder of the shares of Common
Stock deliverable upon such conversion as of the close of business on such date.
Promptly after receipt by the Borrower of this Note and notice, the Borrower
shall issue and deliver, at its expense, to the Lender, or to the nominee or
nominees of such Lender, a certificate or certificates for the number of shares
of its Common Stock due on such conversion. Interest shall accrue on the unpaid
principal amount of this Note converted to the date of conversion, and the
Borrower shall pay such interest at the time of conversion in cash; provided,
                                                                    -------- 
however, that in the case of a conversion of only a portion of the outstanding
- -------                                                                       
principal amount of this Note, the Borrower shall execute and deliver to the
Holder (or its nominee or nominees), at the expense of the Borrower, a
replacement note in a principal amount equal to the unconverted portion of such
Note and dated and bearing interest from the date to which interest has been
paid on such Note or dated the date of such Note if no interest has been paid
thereon.

     No fractional shares of Common Stock shall be issued upon conversion of
this Note. Instead of any fractional share of Common Stock which would otherwise
be issuable upon conversion of this Note, the Borrower shall pay a cash
adjustment in respect of such fractional interest.  The Lender, by its
acceptance thereof, expressly waives any right to receive any fractional share
upon conversion of the Note.

     5.   Events of Default.  An event of default hereunder shall consist of:
          -----------------                                                  

          (i)   a default in the payment by the Borrower to the Lender of
     principal or interest under this Note as and when the same shall become due
     and payable;

          (ii)  an event of default by the Borrower under any other obligation,
     instrument, note or agreement for borrowed money ("Indebtedness"), beyond
     any applicable notice and/or grace period (a "Cross-Default") and the
     aggregate principal amount of such Indebtedness to which such Cross-Default
     relates, together with any such other Indebtedness in which there is a
     Cross-Default, exceeds $250,000;

          (iii) institution of any proceeding by or against the Borrower under
     any present or future bankruptcy or insolvency statute or similar law and,
     if involuntary, if the same are not stayed or dismissed within sixty(60)
     days, or the Borrower's assignment for the benefit

                                       4
<PAGE>
 
     of creditors or the appointment of a receiver, trustee, conservator or
     other judicial representative for the Borrower or the Borrower's property
     or the Borrower's being adjudicated a bankrupt or insolvent.

          Upon the occurrence of any event of default, interest shall accrue on
the outstanding balance of this Note at the Prime Rate plus three percent (3%),
the entire unpaid principal amount of this Note and all unpaid interest accrued
thereon shall, at the sole option of the Lender, without notice, become
immediately due and payable, and the Lender shall thereupon have all the rights
and remedies provided hereunder or now or hereafter available at law or in
equity.

     6.   Summary Proceedings.  Any action, suit or proceeding where the amount
          -------------------                                                  
in controversy as to at least one party, exclusive of interest and costs,
exceeds $1,000,000 ("Summary Proceeding"), arising out of or relating to this
Note, or the breach, termination or validity thereof, shall be litigated
exclusively in the Superior Court of the State of Delaware (the "Delaware
Superior Court") as a summary proceeding pursuant to Rules 124-131 of the
Delaware Superior Court, or any successor rules (the "Summary Proceeding
Rules"). Each of the parties hereto hereby irrevocably and unconditionally (i)
submits to the jurisdiction of the Delaware Superior Court for any Summary
Proceeding, (ii) agrees not to commence any Summary Proceeding except in the
Delaware Superior Court, (iii) waives, and agrees not to plead or to make, any
objection to the venue of any Summary Proceeding in the Delaware Superior Court,
(iv) waives, and agrees not to plead or to make, any claim that any Summary
Proceeding brought in the Delaware Superior Court has been brought in an
improper or otherwise inconvenient forum, (v) waives, and agrees not to plead or
to make, any claim that the Delaware Superior Court lacks personal jurisdiction
over it, (vi) waives its right to remove any Summary Proceeding to the federal
courts except where such courts are vested with sole and exclusive jurisdiction
by statute and (vii) understands and agrees that it shall not seek a jury trial
or punitive damages in any Summary Proceeding based upon or arising out of or
otherwise related to this Note and waives any and all rights to any such jury
trial or to seek punitive damages.

     In the event any action, suit or proceeding where the amount in controversy
as to at least one party, exclusive of interest and costs, does not exceed
$1,000,000 (a "Proceeding"), arising out of or relating to this Note or the
breach, termination or validity thereof is brought, the parties to such
Proceeding agree to make application to the Delaware Superior Court to proceed
under the Summary Proceeding Rules. Until such time as such application is
rejected, such Proceeding shall be treated as a Summary Proceeding and all of
the foregoing provisions of this Section relating to Summary Proceedings shall
apply to such Proceeding.

     If a Summary Proceeding is not available to resolve any dispute hereunder,
the controversy or claim shall be settled by arbitration conducted on a
confidential basis, under the U.S. Arbitration Act, if applicable, and the then
current Commercial Arbitration Rules of the American Arbitration Association
(the "Association") strictly in accordance with the terms of this Note and the
substantive law of the State of Delaware. The arbitration shall be conducted at
the

                                       5
<PAGE>

business by three arbitrators, at least one of whom shall be knowledgeable in
general business matters and one of whom shall be an attorney. Judgment upon the
arbitrators' award may be entered and enforced in any court of competent
jurisdiction. Neither party shall institute a proceeding hereunder unless at
least 60 days prior thereto such party shall have given written notice to the
other party of its intent to do so.

     Neither party shall be precluded hereby from securing equitable remedies in
courts of any jurisdiction, including, but not limited to, temporary restraining
orders and preliminary injunctions to protect its rights and interests but such
remedies shall not be sought as a means to avoid or stay arbitration or a
Summary Proceeding.
 
     7.   Waivers.  The Borrower hereby waives presentment, demand, protest and
          -------                                                              
notice of dishonor and protest, and also waives all other exemptions; and agrees
that extension or extensions of the time of payment of this Note or any
installment or part thereof may be made before, at or after maturity by
agreement by the Lender. Upon default hereunder the Lender shall have the right
to offset the amount owed by the Borrower against any amounts owed by the Lender
in any capacity to the Borrower, whether or not due, and the Lender shall be
deemed to have exercised such right of offset and to have made a charge against
any such account or amounts immediately upon the occurrence of an event of
default hereunder even though such charge is made or entered on the books of the
Lender subsequent thereto. The Borrower shall pay to the Lender, upon demand,
all costs and expenses, including, without limitation, attorneys' fees and legal
expenses, that may be incurred by the Lender in connection with the enforcement
of this Note.
