                                 Common Stock

This prospectus relates to the offer and sale of 163,758 shares of common
stock and, 861,900 shares of common stock and such indeterminate additional
shares of common stock be issued upon the conversion of certain
convertible notes, in the principal amount of $70 million in each case by the
shareholders named in this prospectus. The convertible notes will automatically
convert into shares of our common stock upon the effectiveness of this
registration statement. With respect to one convertible note in the principal
amount of $25 million, the per share conversion price, and therefore the number
of shares of common stock issuable upon conversion of such note, is subject to
adjustment based on the average closing price of our common stock on the Nasdaq
National Market during the 20 trading days prior to the date on which this
registration statement becomes effective. Accordingly, the number of shares of
common stock into which such note is convertible may increase or decrease. The
remaining convertible notes, which have an aggregate principal amount of $45
million, will convert at a price of $59.83 per share, resulting in 752,131
shares of common stock. Based on the average closing price of our common stock
for the 20 trading days prior to February 14, 2000, such convertible note would
be convert into 109,769 shares of our common stock. The remaining convertible
notes, which have an aggregate principal amount of $45 million, will convert at
a price of $59.83 per share, resulting in 752,131 shares of common stock.

The selling shareholders may offer for resale through this prospectus the shares
of common stock at various times at market prices prevailing at the time of sale
or at privately negotiated prices. The selling shareholders may resell the
common stock to or through underwriters, broker-dealers or agents, who may
receive compensation in the form of discounts, concessions or commissions. We
will not receive any of the proceeds from the resale of the common stock offered
through this prospectus. All expenses of registration of the common stock which
may be offered through this prospectus under the Securities Act will be paid by
us (other than underwriting discounts and selling commissions, and fees and
expenses of advisors to the selling shareholder).

Shares of our common stock are quoted on the Nasdaq National Market under the
symbol ''VERT.''  The last reported sale price of the shares on February 11,
2000 was $213 per share.  VerticalNet has applied to list the shares of
common stock offered through this prospectus on the Nasdaq National Market.

         Investing in our common stock involves a high degree of risk.
                        Risk Factors begin on page 5.

commission has approved or disapproved of these securities or passed upon the
accuracy or adequacy of this prospectus.  Any representation to the contrary is

     (1) 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 as if converted at the original
     issuance date. All convertible preferred stock was converted into common
     stock at the IPO date.
     (2) For the periods indicated, earnings were inadequate to cover fixed
     charges. For purposes of determining the deficiency of earnings to fixed
     charges, loss is defined as losses from continuing operations.

     The following table indicates a summary of our balance sheet as of
September 30, 1999. The pro forma column reflects our acquisition of NECX and
the net proceeds from the October 12, 1999, $15 million exercise of the over-

                         Risks Related to Our Business

We have limited operating history upon which you may evaluate us

     We launched our first vertical trade community in October 1995 and have a
limited operating history.  In addition, our revenue model is evolving, making
an evaluation of our future prospects very difficult.  Currently, our Internet-
based 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 e-commerce and business services.  We may not be
able to sustain our current revenues or successfully generate e-commerce or
business services revenue. If we do not generate such revenue, our business,
financial condition and operating results will suffer.   We expect that a
significant percentage of our overall revenues will come from NECX Exchange
which we acquired December 16, 1999.  We may not be able to successfully
integrate the revenue stream of NECX into an e-commerce platform.  If we do not
generate revenue from NECX'S e-commerce applications, our business,
financial condition and operating results will suffer.

We anticipate we will incur continued losses for the foreseeable 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 $38.2 million for
the nine months ended September 30, 1999 actual and $67.1 million on a pro forma
basis, giving effect to the acquisitions of NECX, Isadra, CertiSource, LabX and
Techspex. We expect to continue to incur significant losses in the foreseeable
future.  As of September 30, 1999, our accumulated deficit was $57.5 million.
As a result of our acquisitions, we expect our amortization expense to increase
significantly in the future. Our limited operating history makes predicting our
future operating results, including operating expenses, difficult. Our revenues
may not grow or may not even continue at their current level.

We expect our operating expenses to increase

     Some of our expenses are fixed, including non-cancelable 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 internal sales and marketing operations;

     . enhance our technologies;

     . develop and deploy our e-commerce initiatives;

     . enter into additional sponsorship agreements;

     . broaden our customer support capabilities; and

     . pursue marketing and distribution alliances.

     Expenses will also increase due to the potential impact of goodwill
amortization and other charges resulting from completed and future acquisitions.

                                       5
<PAGE>

     Leading Web sites, browser providers and other Internet distribution
channels may also begin to charge us for providing 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 harmed.


Fluctuations in our quarterly results may cause our stock price to decline

     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 e-commerce and advertising
       medium;

     . dependence on development and adoption of the e-commerce market;

     . the level of demand for our products and services;

     . intense and increased competition;

     . our ability to develop, introduce and market new products and
       enhancements to our existing products on a timely basis;

     . 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 recent and future acquisitions.

     Many of these factors are beyond our control.

     Due to the limited history of businesses relying on the Internet as an
advertising and commercial medium, we believe that period-to-period comparisons
of our operating results are not meaningful, and that such comparisons may not
be accurate indicators of future performance.  Additionally, if our operating
results in one or more quarters do not meet the securities analysts' or our
shareholders' expectations, the price of our common stock may fall.

     In addition, after our acquisition of NECX on December 16, 1999, quarterly
fluctuations in NECX's revenues may disproportionately affect our revenues, due
to NECX's substantial contribution to our overall revenues.


Marketing and distribution alliances may not generate the expected number of new
customers or may be terminated

     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 Lycos.
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. We also may be unable to renew
these marketing and distribution alliance agreements. If any of these agreements
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. In June 1999, as part of our overall reconsideration of
our portal alliances, we terminated a three-year Sponsorship Agreement with
Excite, Inc. entered into on September 30, 1998. Additionally, in October 1999,
we terminated our Sponsorship Agreement with Alta Vista.

                                       6
<PAGE>

     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. If we
are unable to enter into new arrangements, the traffic on our vertical trade
communities may not increase. Additionally, even if we are able to enter into
additional partnerships with search engines, these partnerships may not
necessarily increase the traffic on our vertical trade communities.

     There is intense competition for the Internet products and services,
advertising and sales of goods and services that we offer.

     The market for Internet products and services, advertising and e-commerce
is intensely competitive, evolving and subject to rapid technological change. We
expect competition to intensify as current competitors expand their product
offerings and new competitors enter the market. 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 publications and trade associations.
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.

     Many of our competitors have greater brand recognition and greater
financial, marketing and other resources than ours, and may have well-
established relationships with our existing and prospective customers. This may
place us at a disadvantage in responding to our competitors' pricing strategies,
technological advances, advertising campaigns, strategic partnerships and other
initiatives. Our competitors may also 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 may be negatively impacted.


Acquisitions may disrupt or otherwise have a negative impact on our business

     We have made, and plan to continue to make, significant investments in
complementary Internet and non-Internet traditional companies, technologies and
assets. Acquisitions are subject to the following risks:

     . 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;

     . we may acquire companies in markets in which we have little experience;

     . we may not be able to retain key employees from acquired companies;

     . we may not be able to successfully integrate the services, products and
       personnel of any acquisition into our operations;

     . 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 and incur significant additional losses;

     . our share price could decline following the market's reaction to our
       acquisitions;

     . our amortization expense will increase as a result of acquisitions; and

     . our interest deductions may be disallowed for federal income tax
       purposes.

                                       7
<PAGE>

The integration of NECX into our operations will substantially affect our
revenue model and may be expensive and time-consuming

          We recently acquired NECX, a marketplace for the electronics industry.
For the nine months ended September 30, 1999, NECX generated net revenues of
approximately $28.0 million, all of which was attributable to its off-line
market-making business. For the same period, VerticalNet generated net revenue
of approximately $10.7 million, all of which was derived from our on-line
advertising and e-commerce arrangements. We believe our acquisition of NECX will
result in substantially higher revenues to VerticalNet; however, we plan to
migrate NECX's off-line business to an on-line business. The effect of this
migration on NECX's revenue stream is uncertain. There can be no assurance that
we will be successful in this migration, nor that NECX customers will continue
to use NECX upon its integration.

          In order to operationally integrate NECX into our vertical trade
communities, we have retained Computer Sciences Corporation to design and build
a new on-line exchange for NECX. The cost of designing and building a new
on-line exchange will be significant and this project may take a substantial
period of time to complete. There can be no assurance that this project will be
completed at the cost and on the timeline that we currently contemplate. The
failure of Computer Sciences or VerticalNet to effectively design, build and
integrate the operations of NECX into VerticalNet's on-line trade communities
could adversely affect our business, financial condition and operating results.

Future acquisitions may have a substantial dilutive effect on our stockholders.

          Our growth strategy depends upon the use of acquisitions to expand our
business.  The implementation of this strategy may require us to finance these
acquisitions with shares of our common stock.  Accordingly, our stockholders
may experience substantial dilution because of our acquisition growth strategy.

We currently rely heavily on advertising revenues and if our advertising
revenues decline, our business would suffer

     We currently rely on revenues generated from the sale of advertising on our
vertical trade communities for a significant majority of our revenues. If we do
not continue to develop advertising and other sources of revenues, our business
may suffer. Our ability to increase our advertising revenues depends, 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.

     Additionally, to some of our advertising customers, we provide extended
payment terms over the customer's advertising contract. To the extent that these
amounts are not collected, our advertising revenues, bad debt expense and cash
flows may be negatively impacted.

     We also have barter arrangements where we provide banner advertisements and
storefronts to some of our customers in exchange for advertising on their Web
sites or in their publications. If our barter arrangements do not continue, our
advertising revenues may decline.  For the nine months ended September 30, 1999,
approximately $2.4 million, or 22.9%, of our reported revenue was generated by
barter advertising arrangements.

     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 impair our business, financial condition and operating results.

                                       8
<PAGE>

The seasonality of our advertising revenues and usage causes our overall
revenues to fluctuate

     Some of our revenue is seasonal, which causes our revenues to be lower in
the second and third quarters of each calendar year. As a result, after the
announcement of our results for the second and third quarters of each calendar
year, our stock price may be lower than at other times of the year. 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.


Changes in industry advertising rates could negatively impact our revenues

     Changes in industry pricing practices for advertising rates could
negatively impact our revenues in the future. Currently, we base our storefront
advertising rates on a variety of factors including the maturity of the
particular vertical trade community, the number of storefronts, the amount of
other advertising purchased and the length of the advertising contract. In the
future, advertising rates may be based on different criteria matrices such as
the number of sales inquiries generated or visitors sent from our vertical trade
communities to advertisers' Web sites. These changes could negatively impact our
revenues.


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 impair 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. It may therefore be difficult for us to distinguish our
content and attract users.

     We rely on third parties, such as trade publications and news wires, to
provide some of the content for our vertical trade communities. It is critical
to our business that we maintain and build our existing relationships with
content providers. We may not be able to maintain relationships with the third
parties we depend upon to provide the content for our vertical trade
communities, which could result in decreased traffic on our vertical trade
communities and decreased advertising revenue. 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 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 license fees we pay to content providers may increase

     If licensing fees to content providers increase, our business, financial
condition and operating results may be negatively impacted. These license fees
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.

                                       9
<PAGE>

If we do not develop the "VerticalNet" brand and our vertical trade community
brands, our advertising revenues could decrease

     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 impair our
business, financial condition and operating results if users do not perceive our
products and services to be of high quality.


We may not develop significant revenues from e-commerce, which could adversely
affect our future growth

     For the nine months ended September 30, 1999, approximately 7% of our
revenues were generated from e-commerce. If we do not generate increased revenue
from e-commerce, our business, financial condition and operating results could
be impaired. To generate significant e-commerce revenues, we will have to
continue to build and acquire significant e-commerce capabilities.

     Recent acquisitions to enhance our e-commerce capabilities include NECX,
Isadra, LabX and CertiSource. These acquisitions may not meet our expectations.


Our e-commerce capability depends on real-time accurate product information

  Currently, we are responsible for loading supplier product information into
our database and categorizing the information for search purposes. This process
entails a number of risks, including dependence on our suppliers to provide us
in a timely manner with accurate, complete and current information about their
products, and to promptly update this information when it changes. We will not
derive revenue from these products until this data is loaded in our system.
Timely loading of these products in our database depends upon a number of
factors, including the file formats of the data provided to us by suppliers and
our ability to further automate and expand our operations to accurately load
this data in our product database, any of which could delay the actual loading
of these products.

     In addition, we are generally obligated under our supplier agreements to
load updated product data onto our database within a specified period of time
following its delivery from the supplier. While we intend to further automate
the loading and updating of supplier data on our system, we may not be able to
do so in a timely manner, in part because achieving the highest level of this
automation is dependent upon our suppliers' automating their delivery of product
data to us. If our suppliers do not provide us in a timely manner with accurate,
complete and current information about the products we offer, our database may
be less useful to our customers and users and may expose us to liability.
Although we screen our suppliers' information before we make it available to our
customers and users, we cannot guarantee that the product information available
in our database will always be accurate, complete and current, or comply with
governmental regulations. This could expose us to liability or result in
decreased adoption and use of our vertical trade communities, which could reduce
our revenues and therefore have a negative effect on our results of operations
and financial condition.


If our suppliers do not provide timely and professional delivery of products to
our customers, our business will be harmed

      We rely on our suppliers and manufacturers to deliver products to our
customers in a professional, safe and timely manner. If our suppliers do not
deliver the products to our customers in a professional, safe and timely manner,
then our service will not meet customer expectations and our reputation and
brand will be damaged. In addition, deliveries that are nonconforming, late or
are not accompanied by information required by applicable law or regulations,
could expose us to liability or result in decreased adoption and use of our
vertical trade communities, which could have a negative effect on our business,
results of operations and financial condition. In some instances, we bear the
responsibility for product refunds and returns and the risk of non-
collectibility of accounts receivable from our customers.

                                       10
<PAGE>

We may not be able to effect our growth strategy if we are not able to
consummate future acquisitions

     We have been growing, and plan to continue to grow, our business by
acquisitions. We may not be able to identify additional suitable acquisition
candidates available for sale at reasonable prices or on reasonable terms. Even
if we are able to identify an appropriate acquisition candidate, we may not be
able to negotiate the terms of the acquisition successfully, finance the
acquisition or integrate the acquired business, products or technologies into
our existing business operation. If we are unable to consummate future
acquisitions, our business, financial condition and operating results could be
negatively impacted.

We are growing rapidly and effectively managing our growth may be difficult

     We have rapidly and significantly expanded our operations and expect to
continue to do so both by adding new products, hiring new employees and
acquiring new businesses. This growth has placed, and is expected to continue to
place, a significant strain on our resources and systems.  To manage our growth,
we must implement systems and train and manage our employees. If we fail to
successfully integrate our recent and future acquisitions, our business,
financial condition and operating results could be negatively impacted.

Our international expansion may make it more difficult to manage our business

     In February 2000, we announced the formation of VerticalNet Europe, a joint
venture with British Telecommunications, plc and Internet Capital Group and the
formation of VerticalNet Japan, a joint venture with Softbank Commerce Corp.  We
intend to establish and promote European and Japanese business to business
trade communities through these new joint ventures.  In June 1999, we entered
into a co-branding agreement with Metropolis Transactive (Proprietary) Limited,
a South African company creating on-line marketplaces focused on the African
market. We expect to further expand in international markets. To do so, we plan
to establish international operations, hire additional personnel and establish
relationships with additional suppliers and strategic partners. This expansion
will require significant management attention and financial resources and could
have a negative effect on our business, revenues, financial condition and
results of operations. We may not be able to create or sustain international
demand for our Internet-based, e-commerce business model and services. Even if
we are able to identify an appropriate international joint venture partner, we
may not be able to negotiate the terms of the venture successfully, finance the
venture or integrate the venture partner's business, products or technology into
our existing business operation, or we may become dependent on our joint venture
partners.  In addition, our international business may be subject to a variety
of risks, including government regulation, difficulties in collecting
international accounts receivable, longer payment cycles, increased costs
associated with maintaining international marketing efforts, the introduction of
non-tariff barriers, possible currency risks and higher duty rates and
difficulties in enforcement of contractual obligations and intellectual property
rights, including licensing rights. These factors may have a negative effect on
any future international sales and, consequently, on our business, results of
operations and financial condition.

Risk of failure of our computer and communications hardware systems increases
without back-up facilities

  The performance of our computer and communications hardware systems is
critical to our business and reputation and our ability to process transactions,
provide high quality customer service and attract and retain customers,
suppliers, users and strategic partners. Any system interruptions that cause our
vertical trade communities to be unavailable to users may reduce the
attractiveness of our vertical trade communities to advertisers and could impair
our business, financial condition and operating results. We maintain most of our
computer systems in two Web-hosting facilities in New Jersey.  We do not
currently have back-up or redundant facilities for our computer systems.
Interruptions could result from natural disasters as well as power loss,
telecommunications failure and similar events.

                                       11
<PAGE>

Capacity limits on our technology, transaction processing system and network
hardware and software may be difficult to project and we may not be able to
expand and upgrade our systems to meet increased use

     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 suffer.

     Our acquisition of Isadra, including its agent-communication and agent-
brokering architecture, may not be successfully integrated into our existing
technology.

Our market is characterized by rapid technological change, which we may not be
able to keep up with in a cost-effective way

     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 suffer. To be
successful, we must adapt to our rapidly changing market by continually
improving the responsiveness, services and features of our vertical trade
communities, by developing new features to meet customer needs and by
successfully developing and introducing new versions of our Internet-based, e-
commerce business model on a timely basis. Our success will depend, in part, on
our ability to acquire or 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.

We may not be able to acquire or maintain easily identifiable Web addresses or
prevent third parties from acquiring Web addresses similar to ours

     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 impair 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. 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.

We may compete with Internet Capital Group, our largest shareholder

     As a result of its stock ownership and board representation, Internet
Capital Group, LLC is in a position to significantly affect our business
strategy and operations, including corporate actions such as mergers or takeover
attempts in a manner that could conflict with the interests of our public
shareholders. At December 31, 1999, Internet Capital Group owned 12,295,010
shares, or 34.1%, of our common stock. Internet Capital Group also owns warrants
to purchase an additional 239,312 shares of common stock. Two representatives of
Internet Capital Group remain on our board of directors. We may compete with
Internet Capital Group for Internet-related opportunities. Internet Capital
Group seeks to expand, in part through acquisitions and investments, its number
of business-to-business assets. Internet Capital Group, therefore, may seek to
acquire companies that we would find attractive. While we may partner with
Internet Capital Group on future acquisitions, we have no current contractual
obligations to do so. We do not have any contracts or other

                                       12
<PAGE>

understandings that would govern resolution of this potential conflict. This
competition, and the potential conflict posed by the designated directors, may
deter companies from partnering with us and may limit our business
opportunities.


Our success is dependent on our key personnel who we may not be able to retain
and we may not be able to hire enough additional personnel to meet our hiring
needs

     We believe that our success depends 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. Only one member of our senior management has an
employment agreement. 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 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
impaired if we cannot hire and retain suitable personnel.


Our systems may not be Year 2000 compliant, which could cause our vertical trade
communities to be unavailable for a period of time after January 1, 2000, which
could in turn have a negative impact on our business, operating results and
financial position

     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 and
other equipment used internally. 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 harmed.

     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. 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.


                     Risks Related to the Internet Industry

Our success depends on the development of the e-commerce market, which is
uncertain

     Business-to-business e-commerce is a new and emerging business practice
that remains largely untested in the marketplace. If e-commerce does not grow or
grows slower than expected, our business will suffer. Our long-term success
depends on widespread market-acceptance of e-commerce.

     A number of factors could prevent such acceptance, including the following:

     . e-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;

                                       13
<PAGE>

     . security and confidentiality concerns of customers and suppliers;

     . increased government regulation or taxation may adversely affect the
       viability of e-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 e-commerce
       transactions could discourage its acceptance and growth.


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 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 suffer.

     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 suffer if the market
for Internet advertising fails to develop or develops slower than expected.


Adoption of the Internet as an e-commerce medium is uncertain

     Our market is new and rapidly evolving, and depends on the increased
acceptance and use of the Internet as a medium of commerce. Our business would
suffer if Internet usage does not continue to grow and if the Internet is not
adopted as an e-commerce medium. Internet usage may be inhibited by a number of
reasons, such as:

     . inadequate development of the necessary infrastructure;

     . security and confidentiality concerns of customers and suppliers;

     . inconsistent quality of service;

     . lack of human contact that current traditional suppliers provide; and

     . lack of availability of cost-effective, high-speed service.


Security risks and concerns may deter the use of the Internet for conducting e-
commerce

     The secure transmission of confidential information over the Internet is
essential to maintaining customer and supplier confidence. Concerns regarding
security of transactions and transmitting confidential information over the
Internet may negatively impact our e-commerce business.

     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 on-line transactions. If we do not add
sufficient security features to future product releases, our products may not
gain market acceptance or we may incur additional legal exposure. 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

                                       14

<PAGE>

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 e-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 impair our business, financial condition and
operating results.


Limited Internet infrastructure may affect service

     The accelerated growth and increasing volume of Internet traffic may cause
performance problems, slowing the adoption of our Internet-based purchasing
solution. The growth of Internet traffic due to very high volumes of use over a
relatively short period of time has caused frequent periods of decreased
Internet performance, delays and, in some cases, system outages. This decreased
performance is caused by limitations inherent in the technology infrastructure
supporting the Internet and the internal networks of Internet users. If Internet
usage continues to grow rapidly, the infrastructure of the Internet and its
users may be unable to support the demands of growing e-commerce usage, and the
Internet's performance and reliability may decline. If our existing or potential
customers experience frequent outages or delays on the Internet, the adoption or
use of our Internet-based, e-commerce business model may grow more slowly than
we expect or even decline. Our ability to increase the speed and reliability of
our Internet-based business model is limited by and depends upon the reliability
of both the Internet and the internal networks of our existing and potential
customers. As a result, if improvements in the infrastructure supporting both
the Internet and the internal networks of our customers and suppliers are not
made in a timely fashion, we may have difficulty obtaining new customers, or
maintaining our existing customers, either of which could reduce our potential
revenues and have a negative impact on our business, results of operations and
financial condition.


                    Proprietary, Regulatory and Legal Risks

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 filed applications with the U.S. Patent and Trademark Office
to obtain registrations for ten of our marks. To date, five registrations have
been issued. 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. Generally, our domain names for our vertical trade
communities are not protectable 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 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 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

                                       15
<PAGE>

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 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.


We may be exposed to product liability claims

     We face potential liability for claims based on the nature of the products
that we sell and distribute utilizing the Internet, including claims for breach
of warranty, product liability, misrepresentation, violation of governmental
regulations and other commercial claims.  Most of the manufacturers whose
products we distribute have warranties on those products.  We pass that warranty
through to our customers whenever possible.  However, in some instances we bear
the risk of loss of revenue from the product sale if a purchaser does not pay
for a defective product. Although we maintain general liability insurance, our
insurance may not cover some claims or penalties, is subject to policy limits
and exclusions and may not adequately indemnify us or our employees from any
civil, governmental or criminal liability. Furthermore, this insurance may not
be available at commercially reasonable rates in the future. Any liability not
covered by our insurance or in excess of our insurance coverage could have a
negative effect on our business, financial condition and operating results.


We are subject to government regulation that exposes us to potential liability
and negative publicity

     We currently rely upon our suppliers to meet all packaging, distribution,
labeling, hazard and health information notices to purchasers, record keeping
and licensing requirements applicable to our business during the entire
transaction. Our reliance on suppliers' regulatory due diligence assessment of
purchasers and the compliance by suppliers and purchasers with applicable
governmental regulations may not be sufficient if we are required to have our
own licenses. For example, if we are held to be a seller or a distributor of
regulated products because we took legal title, we may have inadvertently
violated some governmental regulations by not having the appropriate license or
permit and may be subject to potentially severe civil or criminal penalties and
fines for each offense. We are unable to verify that our suppliers have in the
past complied, or will in the future comply, with the applicable governmental
regulatory requirements, or that their actions are adequate or sufficient to
satisfy all governmental or other legal requirements that may be applicable to
our sales. We could be fined or exposed to civil or criminal liability,
including monetary fines and injunctions, and we could receive potential
negative publicity, if the applicable governmental regulatory requirements have
not been, or are not being, fully met by our suppliers or by us directly.
Negative publicity, fines and liabilities could also occur if an unqualified
person, or even a qualified customer, lacks the appropriate license or permits
to sell, use or ship, or improperly receives a dangerous or unlicensed product
through us. We do not maintain any reserve for potential liabilities resulting
from government regulation.

     It is also possible that a number of laws and regulations may be adopted or
interpreted in the United States and abroad with particular applicability to the
Internet. These laws and regulations may, for example, cover issues such as user
privacy, freedom of expression, pricing, content and quality of products and
services, taxation, advertising, intellectual property rights, access charges
and information security.  The enactment of such laws could have a negative
effect on our business, financial condition and operating results.

                         Risks Related to this Offering

We may not have sufficient cash flow to service our debt

     As of September 30, 1999, we had approximately $101,739,000 in long term
debt. After September 30, 1999, an additional $15 million in debt resulted from
the exercise of the over-allotment provision of our 5 1/4% convertible
subordinated debentures due 2004. Currently, we are not generating sufficient
cash flow to satisfy the annual debt service payments required as a result of
our September 1999 offering of convertible subordinated debentures. If we are
unable to satisfy our debt service requirements, substantial liquidity problems
could result, which would negatively impact our future prospects.


                                       19
<PAGE>

We may require additional capital for our operations that could have a negative
effect on your investment

     We currently anticipate that the net proceeds of our September 1999
offering of debentures, together with our existing borrowing arrangements and
available funds, will be sufficient to meet our anticipated needs for working
capital and capital expenditures for at least the next 12 months. We may need to
raise additional funds in the future in order to fund rapid expansion, to pursue
customer sales and implementation, to develop new or enhanced solutions and
services, to respond to competitive pressures or to acquire complementary
businesses, technologies or services.

     If we raise additional funds through the issuance of equity or convertible
debt securities, the percentage ownership of our shareholders will be reduced,
shareholders may experience additional dilution and these securities may have
powers, preferences and rights that are senior to those of the rights of our
common stock. We cannot be certain that additional financing will be available
on terms favorable to us if at all. If adequate funds are not available or not
available on acceptable terms, we may be unable to fund our expansion, promote
our brand identity, take advantage of acquisition opportunities, develop or
enhance services or respond to competitive pressures. Any inability to do so
could have a negative effect on our business, revenues, financial condition and
results of operations.


Shares eligible for future sale by our current shareholders may cause our stock
price to decline

     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, then the market price of our common stock could fall.
Restrictions under the securities laws limit the number of shares of common
stock available for sale in the public market.

     As of January 1, 2000, the holders of up to 24,321,679 shares of common
stock and warrants to purchase 395,208 shares of common stock have demand and
piggy-back registration rights. The exercise of such rights could adversely
affect the market price of our common stock. We have also filed a registration
statement to register shares of common stock under our stock option and employee
stock purchase plans. Shares issued upon exercise of stock options and employee
stock purchase plans 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 our
shareholders. Our articles of incorporation provide that our board of directors
may issue preferred stock without 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 price is likely to remain highly volatile

     The market price of our common stock has been and will likely continue 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. Our stock may not trade at the
same levels as other Internet stocks, and Internet stocks in general may not
sustain their current market prices.

                                       18
<PAGE>

     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 models 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;

     .    failure to meet analysts' expectations;

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

     .    capital commitments;

     .    additions or departures of key personnel;

     .    sales of common stock; and

     .    stock market price and volume fluctuations, which are particularly
          common among highly volatile securities of Internet companies.

     Many of these factors are beyond our control. These factors may cause the
market price of our common stock to fall, regardless of our operating
performance.

                           FORWARD-LOOKING STATEMENTS

     Our disclosure and analysis in this prospectus contain some forward-looking
statements. Forward-looking statements give our current expectations or
forecasts of future events. You can identify these statements by the fact that
they do not relate strictly to historical or current facts. Such statements may
include words such as "anticipate," "estimate," "expect," "project," "intend,"
"plan," "believe" and other words and terms of similar meaning in connection
with any discussion of future operating or financial performance. In particular,
these include among other things, statements relating to e-commerce strategy,
acquisition and expansion strategy, development of services, use of proceeds,
projected capital expenditures, liquidity, development of additional revenue
sources, development and maintenance of profitable marketing and distribution
alliances, market acceptance of the Internet, acquisition and/or development of
profitable new vertical trade communities, technological advancement, ability to
develop "brand" identification and global expansion.

     Any or all of our forward-looking statements in this prospectus may turn
out to be wrong. They can be affected by inaccurate assumptions we might make or
by known or unknown risks and uncertainties. Many factors mentioned in our
discussion in this prospectus will be important in determining future results.
Consequently, no forward-looking statement can be generated. Actual future
results may vary materially.

     We undertake no obligation to publicly update any forward-looking
statements, whether as a result of new information, future events or otherwise.
You are advised, however, to consult any additional disclosures we make in our
reports to the SEC on Forms 10-K, 10-Q and 8-K. Also note that we provide a
cautionary discussion of risks and uncertainties under "Risk Factors" on page
5 of this prospectus. These are factors that we think could cause our actual
results to differ materially from expected results. Other factors besides those
listed here could also adversely affect us. This discussion is provided as
permitted by the Private Securities Litigation Reform Act of 1995.


                                USE OF PROCEEDS

     We will not receive any proceeds from the resale of the common stock
offered through this prospectus.

                          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. VerticalNet is a Pennsylvania corporation and is subject to the
Pennsylvania Business Corporation Law of 1988.


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.


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 one
year for the class I directors, two years for the class II directors and three
years for the class III directors. This could prevent a party who acquires
control of the majority of the outstanding voting stock from obtaining control
of the board of directors.

     Our shareholders do not have the right to cumulative voting in the election
of directors.

Shareholder Action by Written Consent

     Under Pennsylvania law, any action that may be taken at a meeting of the
shareholders may be taken without a meeting if such action is authorized by the
unanimous written consent of all shareholders entitled to vote at a meeting for
such purposes.

                                       21
<PAGE>

Special Meetings

     Our articles of incorporation and bylaws provide that special meetings of
our shareholders may be called only by the board or by our chairman or chief
executive officer. 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 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 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 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

<PAGE>

"Risk Factors--Risks Related to this Offering--Anti-takeover provisions and our
right to issue preferred stock could make a third-party acquisition of us
difficult," "--Common Stock" and "--Preferred Stock."


Registration Rights

     In addition to the registration rights granted in connection with the
offering of the debentures, the holders of up to 24,321,679 shares of common
stock and warrants to purchase 395,208 shares of common stock are entitled to
certain registration rights. These rights are provided under the terms of
agreements between us and the holders of such securities. Such agreements
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.

     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. 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 tradeable without restriction under the Securities Act of 1933
immediately upon the effectiveness of such registration. "Risk Factors--Risks
Related to this Offering--Shares eligible for future sale by our current
shareholders may cause our stock price to decline" and "Shares Eligible for
Future Sale."


Transfer Agent

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

                             SELLING SHAREHOLDERS

     The shares of common stock and the shares of common stock underlying the
convertible notes were originally issued by VerticalNet in connection with the
acquisitions of LabX Technologies, Inc., TextileWeb, Inc., GovCon, Inc. and NECX
Exchange, LLC. In each case, such transactions were exempt from the registration
requirements of the Securities Act. VerticalNet has agreed with each selling
shareholder to file the registration statement to register for resale the shares
of common stock set forth below.

     The following table sets forth information, as of [December 31, 1999], with
respect to the selling shareholders, (1) the number of shares registered for
sale; (2) the number and approximate percentage of shares beneficially owned ;
and (3) the number and approximate percentage of shares to be owned after the
completion of this offering. The information below is based on information
provided by or on behalf of the selling shareholders. The selling shareholders
may offer all, some or none of the common stock. Because the selling
shareholders may offer all or some portion of the common stock, no estimate can
be given as to the amount of the common stock that will be held by the selling
shareholders upon termination of such sales. In addition, the selling
shareholders identified below may have sold, transferred or otherwise disposed
of all or a portion of their common stock since the date on which they provided
the information regarding their common stock in transactions exempt from the
registration requirements of the Securities Act.

(1)  All 861,900 shares of common stock set forth herein are
     shares of common stock into which the notes are convertible. The
     convertible notes will automatically convert into common stock upon the
     effectiveness of this registration statement. With respect to one
     convertible note in the principal amount of $25 million, the per share
     conversion price, and therefore the number of shares of common stock
     issuable upon conversion of such note, is subject to adjustment based on
     the average closing price of our common stock on the Nasdaq National Market
     during the 20 trading days prior to the date on which this registration
     statement becomes effective. Accordingly, the number of shares of common
     stock into which such note is convertible may increase or decrease. Based
     on the average closing price of our common stock for the 20 trading days
     prior to February 14, 2000, such note would be convertible into 109,769
     shares of our common stock. The remaining convertible notes, which have an
     aggregate principal amount of $45 million, will convert at a price of
     $59.83 per share, resulting in 752,131 shares of common stock.

(2)  Does not include an option to acquire 10,000 shares of common stock. Does
     not include 22,200 shares of common stock beneficially owned by Joan
     Kafato, as Robert Kafato disclaims beneficial ownership.

(3)  Includes 10,600 shares held by Barry J. Friedman, principal manager of
     Pride Consulting, LLC.

(4)  Does not include 33,210 shares of common stock beneficially owned by
     Robert Kafato, as to which Ms. Kafato disclaims beneficial ownership.

     Khera, as to which Dheeraj Khera disclaims beneficial ownership.

                             PLAN OF DISTRIBUTION


          The selling shareholders and their successors, which term includes
their transferees, pledgees or donees or their successors, may sell the common
stock directly to purchasers or through underwriters, broker-dealers or agents,
who may receive compensation in the form of discounts, concessions or
commissions from the selling shareholders or the purchasers, which discounts,
concessions or commissions as to any particular underwriter, broker-dealer or
agent may be in excess of those customary in the types of transactions involved.

          The common stock may be sold in one or more transactions at fixed
prices, at prevailing market prices at the time of sale, at prices related to
such prevailing market prices, at varying prices determined at the time of sale,
or at negotiated prices. Such sales may be effected in transactions, which may
involve crosses or block transactions (1) on any national securities exchange or
quotation service on which the debentures or the common stock may be listed or
quoted at the time of sale, (2) in the over-the-counter market, (3) in
transactions otherwise than on such exchanges or services or in the over-the-
counter market, (4) through the writing of options, whether such options are
listed on an options exchange or otherwise, or (5) through the settlement of
short sales. In connection with the sale of the common stock, the selling
shareholders may enter into hedging transactions with broker-dealers or other
financial institutions which may in turn engage in short sales of the common
stock and deliver these securities to close out such short positions, or loan or
pledge the common stock to broker-dealers that in turn may sell these
securities.

     The aggregate proceeds to the selling shareholders from the sale of the
common stock offered by them hereby will be the purchase price of such common
stock less discounts and commissions, if any. Each of the selling shareholders
reserves the right to accept and, together with their agents from time to time,
to reject, in whole or in part, any proposed purchase of common stock to be made
directly or through agents. We will not receive any of the proceeds from this
offering.

     Our common stock is listed for trading on the Nasdaq National Market. We
intend to list the common stock offered through this prospectus for trading on
the Nasdaq National Market.

     In order to comply with the securities laws of some states, if applicable,
the common stock may be sold in such jurisdictions only through registered or
licensed brokers or dealers. In addition, in some states the common stock may
not be sold unless it has have been registered or qualified for sale or an
exemption from registration or qualification requirements is available and is
complied with.

     The selling shareholders and any underwriters, broker-dealers or agents
that participate in the sale of the common stock, may be "underwriters" within
the meaning of Section 2(11) of the Securities Act. Any discounts, commissions,
concessions or profit they earn on any resale of the shares may be underwriting
discounts and commissions under the Securities Act. Selling shareholders who are
"underwriters" within the meaning of Section 2(11) of the Securities Act will be
subject to the prospectus delivery requirements of the Securities Act. The
selling shareholders have acknowledged that they understand their obligations to
comply with the provisions of the Exchange Act and the rules thereunder relating
to stock manipulation, particularly Regulation M, and have agreed that they will
not engage in any transaction in violation of such provision.

     In addition, any securities covered by this prospectus which qualify for
sale pursuant to Rule 144 of the Securities Act may be sold under Rule 144
rather than pursuant to this prospectus. A selling shareholder may not sell any
common stock described herein and may not transfer, devise or gift such
securities by other means not described in this prospectus.

     To the extent required, the specific common stock to be sold, the names of
the selling shareholders, the respective purchase prices and public offering
prices, the names of any agent, dealer or underwriter, and any

                                      26

applicable commissions or discounts with respect to a particular offer will be
set forth in an accompanying prospectus supplement or, if appropriate, a post-
effective amendment to the registration statement of which this prospectus is a
part.

ITEM 15. 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 Company 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 Company 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 Company pursuant to the foregoing provisions, the Company 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 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
<PAGE>

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 8 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 Article 8 of 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.

ITEM 17. UNDERTAKINGS.

  The undersigned registrant hereby undertakes:

     (1)  To file, during any period in which any offers or sales are being
made, a post-effective amendment to this registration statement:



          (i)   To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

          (ii)  To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent post-
effective amendment hereof) which, individually or in aggregate, represent a
fundamental change in the information set forth in the registration statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high and of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement; and

          (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any other
material change to such information in the registration statement.

     (2)  That for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities
<PAGE>

being offered therein and the offering of such securities at the time may be
deemed to be the initial bona fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
of the securities which are being registered which remain unsold at the
termination of the offering.

     (4)  That for purposes of determining any liability under the Securities
Act of 1933, each filing of the registrant's annual report pursuant to section
13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
section 15(d) of the Securities Exchange Act of 1934) that is incorporated by
reference in the registration statement 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

     (5)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
by the Securities Act of 1933 and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by 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 of 1933 and will be governed by the final adjudication of such
issue.

VerticalNet, Inc.
700 Dresher Rd., Suite 100
Horsham, PA 19044


Ladies and Gentlemen:


     I have acted as counsel to you in connection with the registration under
the Securities Act of 1933, as amended, by VerticalNet, Inc. (the "Company") of
(i) 163,758 shares (the "Shares") of Common Stock of the Company, $.01 par value
per share (the "Common Stock"), and (ii) 861,900 shares of Common Stock and
such indeterminate additional shares of Common Stock (the "Conversion Shares")
required for issuance upon conversion of the Convertible Notes dated December
16, 1999 between VerticalNet, Inc. and NECX Exchange Trust (the "Convertible
Notes"). The Shares and the Conversion Shares are to be offered and sold by
certain security holders of the Company. In this regard, I have participated in
the preparation of a Registration Statement on Form S-3 relating to the Shares
and the Conversion Shares (the "Registration Statement") which you are filing
with the Securities and Exchange Commission.

     I have examined the Registration Statement and such documents and records
of the Company and other documents as I have deemed necessary for the purpose of
this opinion. In all examinations made by me in connection with this opinion
letter, I have assumed the genuineness of all signatures, the legal capacity of
all natural persons executing agreements, instruments or documents, the
completeness and authenticity of all records and documents submitted to me as
originals, and the conformity with the originals of all documents submitted to
me as copies.  Based upon the foregoing, I am of the opinion that (i) the Shares
have been duly authorized, validly issued, fully paid and nonassessable and (ii)
upon conversion of the Convertible Notes in accordance with their terms, the
Conversion Shares will be duly authorized, validly issued, fully paid and
nonassessable.
<PAGE>

     The foregoing opinions shall be limited to the federal laws of the United
States of America and the laws of the Commonwealth of Pennsylvania.

     I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to me in the Prospectus included in
the Registration Statement under the heading "Legal Matters."  In giving such
consent, I do not thereby admit that I am in the category of persons whose
consent is required under Section 7 of the Securities Act.

Very truly yours,


/s/ James W. McKenzie, Jr.

migrating the contents and functionality of the Active Websites to such computer
systems as Purchaser shall direct.

Business under which Seller is the licensee, and (ii) to maintain the existing
content and functionality of the Active Websites.  Any costs associated with the
foregoing incurred on or after the Closing Date shall be borne by Purchaser.

     5.8  Customers.  Seller agrees and acknowledges that effective as of the

Closing users accessing the Active Websites and any and all other customers of

     5.9  Purchaser Common Stock Options.  Purchaser has reserved 25,000 shares
          ------------------------------
of the Common Stock of the Purchaser for grants of options (the "Purchaser
                                                                 ---------
Options") to Shareholders after the Closing Date, of which 12,500 shares of
- -------
Common Stock of the Purchaser shall be for grants of options to Rick A. Reddel
and 12,500 shares of Common Stock of the Purchaser shall be for grants of

                                                 ----
Purchaser's stock option policies.  All Purchaser Options shall be granted with
an exercise price equal to the closing price of the Common Stock of the
Purchaser on the date of grant (or if such day is not a trading day, the last
trading day prior to the date of grant).  For the purposes of this Section 5.9,
the closing price of Common Stock of the Purchaser on a trading day shall be the
day's last trade price as reported by the Nasdaq National Market.  The Purchaser
Options shall vest in accordance with Purchaser's customary four-year vesting
schedule.

     5.10 Tax-Free Reorganization.  The parties to this Agreement intend that
          -----------------------
the transactions provided for in this Agreement shall constitute a
reorganization as defined in Section 368(a )(1)(C) of the Internal Revenue Code
of 1986, as amended, for income tax purposes.  Notwithstanding anything to the
contrary in this Agreement nor in any other instrument executed pursuant to this
Agreement, the parties shall not take or make any action that would prevent such
qualification.  Each of the parties shall complete all relevant tax returns
consistent with such qualification and shall not take any positions inconsistent
with such qualification.

the Purchaser for grants of options to such individuals, and will grant such
options upon the later of acceptance of employment or the Closing Date with an
exercise price equal to the closing price of the Common Stock of the Purchaser
on the date of grant (or if such day is not a trading day, the last trading day
prior to the date of grant). For the purposes of this Section 5.12, the closing
price of Common Stock of the Purchaser on a trading day shall be the day's last
trade price as reported by the Nasdaq National Market. The Purchaser Options
shall vest in accordance with Purchaser's customary four-year vesting schedule.

6.   Covenants of Purchaser.
     ----------------------

                                      -16-
<PAGE>

     6.1  Monetization of Securities.  Purchaser shall not prohibit the
          --------------------------
monetization of one-third of the Stock Consideration in the aggregate by the
Shareholders.  The foregoing rights shall be effective upon the Closing.

     6.2  Registration Rights.  Should the Shareholders choose not to monetize
          -------------------
one-third of the Stock Consideration in the aggregate as provided in 6.1(a),
then the following rights shall apply.  For the purposes of the foregoing
sentence, monetization shall not be deemed to include the incurrence of
indebtedness secured by the stock.

          (a)  Purchaser shall prepare and use its best efforts, on or prior to
February 28, 2000 (the "Required Filing Date") to file with the Commission a
registration statement with respect to the resale of an aggregate of one-third
of the Stock Consideration (the "Shares") by the Shareholders or their permitted
assignees (the "Required Registration Statement") and thereafter shall cause
such registration statement to be declared effective under the Securities Act as
promptly as practicable but in no event later than March 31, 2000 (the "Required
Effective Date").  Purchaser shall file a notification form for the listing of
additional shares to cover the listing of the Shares on the Nasdaq National
Market, or such other market or exchange, if any, on which the Common Stock
shall trade.  Purchaser shall use its best efforts to cause the Required
Registration Statement to remain effective for a period of one year.  Purchaser
acknowledges that the Shareholders are relying on Purchaser's commitment to
cause the Required Registration Statement to become effective not later than the
Required Filing Date, and agrees that if for any reason the Required
Registration Statement is not declared effective by such date (as it may be
extended as herein provided), even if Purchaser is using its best efforts to
cause such effectiveness to be declared, then the Shareholders shall be entitled
to recover damages for any consequential loss incurred.  If the Required
Registration Statement shall not become effective by the Required Effective
Date, at the sole option and request of the Shareholders, in lieu of the
Required Registration Statement, the Purchaser will pay the processing costs
associated with monetization of the Shares, such costs not to exceed $15,000
(the "Processing Costs").  Should Shareholders not request Purchaser to pay such
Processing Costs, the commitment of the Purchaser to cause the Required
Registration Statement to become effective shall not be otherwise changed.

          (b)  If Purchaser proposes to file a registration statement with
respect to the Common Stock prior to the filing of the Required Registration
Statement, Purchaser shall give prompt notice to the Shareholders and will
include in such registration (the "Piggyback Registration") subject to the
allocation provisions discussed in Section 6.2(d) and 6.2(e), all Shares with
respect to which Purchaser has received written request for inclusion within
five (5) Business Days after such notice is given by Purchaser; provided,
however, that the Shareholders shall have no Piggyback Registration rights in
connection with a registration statement filed in connection with Purchaser's 5
1/4% Convertible Subordinated Debentures (the "Convertible Debentures"). No
Purchaser registration statement shall be declared effective unless and until
the Required Registration Statement shall have been declared effective, except
for the registration statement for

                                      -17-
<PAGE>

the Convertible Debentures or if the Required Registration Statement is not
being declared effective due to a comment from the Commission that relates only
to the Shareholders.

          (c)  Purchaser will pay the expenses related to registration of the
Shares; provided, however, the Shareholders shall pay any underwriting
commissions related to the registration of the Shares.

          (d)  If a Piggyback Registration is an underwritten primary
registration on behalf of Purchaser and the managing underwriter advises
Purchaser in writing that marketing factors require a limitation on the number
of Shares to be offered and sold, there shall be included in the offering only
that number of Shares, if any, that such managing underwriter reasonably
believes, in its sole discretion, will not jeopardize the success of the
offering.

          (e)  If a Piggyback Registration is initiated as an underwritten
secondary registration on behalf of the holders of the Common Stock, and the
managing underwriters advise Purchaser in writing that marketing factors require
a limitation on the number of Shares to be offered and sold, Purchaser will
allocate the securities to be included as follows: pro rata on the basis of the
number of shares of Common Stock owned among (i) any other Person selling in the
registration and (ii) the Shareholders.

          (f)  If a Piggyback Registration is underwritten, the Shareholders
shall not be entitled to select the investment bank(s) or manager(s) nor shall
the Shareholders be entitled to make decisions regarding the underwriting
arrangements for the offering.

          (g)  If, prior to the Required Filing Date, Purchaser files a
registration statement with the Commission covering shares of its Common Stock
underlying the Convertible Debentures, Purchaser shall, within five (5) Business
Days of such filing, file the Required Registration Statement.

          (h)  Purchaser shall have no obligations under this Section 6.2 until
the Closing Date. If Purchaser files a registration statement covering shares of
its Common Stock underlying the Convertible Debentures prior to the Closing,
Purchaser, shall, within five (5) Business Days after the Closing, file a
registration statement covering the Shares.


7.   Securities Act and Restrictions on Purchaser Stock.
     --------------------------------------------------

     7.1  Purchase Entirely for Own Account. The Seller Parties acknowledge and
          ---------------------------------
agree that the shares of Common Stock of the Purchaser to be received by
Shareholders as a liquidating distribution from the Seller will be acquired for
investment for each Shareholder's own account, not as a nominee or agent, and
not with a view to the resale or distribution of any part thereof, and that the
Shareholders have no present intention of selling, granting any participation
in, or otherwise distributing the same, but subject to the ability of the
Shareholders to distribute a Shareholder's

                                      -18-
<PAGE>

assets (including the Stock Consideration) to the Shareholder's affiliates (as
such term is defined in Section 144 of the Securities Act).

     7.2  Investment Experience.  The Shareholders represent and warrant that
          ---------------------
the Shareholders can bear the economic risk of an investment in Common Stock of

experience in financial or business matters that the Shareholders are capable to
protect the Shareholders' own interests in connection with the acquisition of
Common Stock of the Purchaser.

     7.3  Information Supplied.  The Shareholders represent and warrant that the
          --------------------

answers from the officers of Purchaser concerning the terms and conditions of
the transaction contemplated by this Agreement and the shares of Common Stock of
the Purchaser to be issued in connection therewith. The Shareholders represent
and warrant that the Shareholders have asked any and all questions that the

     7.4  Restricted Securities. The Shareholders understand that the shares of
          ---------------------
Common Stock of the Purchaser to be received by the Shareholders are
characterized as "restricted securities" under the federal securities laws
inasmuch as they are being acquired from Purchaser in a transaction not
involving a public offering and that under such laws and applicable regulations
such securities may not be resold without registration under the Securities Act,
except in certain limited circumstances.  In this connection, the Shareholder
represent that Shareholders are familiar with Rule 144 under the Securities Act,
as presently in effect, and understands the resale limitations imposed thereby
and by the Securities Act.

     7.5  Further Limitations on Disposition.  Without in any way limiting the
          ----------------------------------
representations set forth above and subject to the terms and conditions set
forth in the Lock-Up Agreements, the Shareholders further agree not to make any
disposition of all or any portion of the shares representing the Stock
Consideration except to the Shareholder's affiliates unless and until:

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

          (b)  The Shareholders shall have notified Purchaser of the proposed
disposition and shall have furnished Purchaser with a detailed statement of the
circumstances surrounding the proposed disposition, and if reasonably requested
by Purchaser, the Shareholders shall have furnished Purchaser with an opinion of
counsel, reasonably satisfactory to Purchaser, that such disposition will not
require registration of such shares under the Securities Act.  It is agreed that

                                      -19-
<PAGE>

Purchaser will not require opinions of counsel for transactions made pursuant to
Rule 144 by the Shareholders except in unusual circumstances.

Notwithstanding the provisions of paragraphs (a) and (b) above, no such
registration statement or opinion of counsel shall be necessary for a transfer
by a Shareholder (i) to an affiliate of the Shareholder, or the transfer by
gift, will or intestate succession to the Shareholder's spouse or lineal
descendants or ancestors, if the transferee agrees in writing to be subject to
the terms of this Section 7 to the same extent as if he or she were a
Shareholder, or (ii) at any time after the provisions of subparagraph (k) of
Rule 144 are applicable to the Shareholders.

     7.6  Legends.  It is understood that the certificates evidencing the Stock
          -------
Consideration may bear the following legend:

          "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR
          ANY STATE SECURITIES OR BLUE SKY LAWS. THEY MAY NOT BE SOLD,
          OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF
          A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE
          SECURITIES UNDER THE SECURITIES ACT AND ANY APPLICABLE STATE
          SECURITIES AND BLUE SKY LAWS OR AN OPINION OF COUNSEL
          SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT
          REQUIRED OR UNLESS SOLD PURSUANT TO RULE 144 OF THE
          SECURITIES ACT."

     8.4  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, and in any case within seven (7) calendar days, 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.

          (a)  The Indemnifying Party shall have thirty (30) calendar 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

                                      -22-
<PAGE>

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.

          (b)  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, which consent shall not be
unreasonably withheld; 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.

          (c)  If the Indemnifying Party shall fail to so elect to defend or
settle such claim (exercising reasonable business judgment) at its own expense,
within thirty (30) calendar 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 Indemnified Party.

          (d)  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 fifteen (15)
calendar days after delivery thereof to elect, in writing to the Indemnified
Party, to settle the claim at its own expense. If the Indemnifying Party (i)
does not notify the Indemnified Party within fifteen (15) calendar days after
the Indemnified Party's notice that it disputes such claim or (ii) notifies the
Indemnified Party that it does not dispute such claim, the amount of such claim
shall be conclusively deemed as a liability of the Indemnifying Party. If the
Indemnifying Party notifies the Indemnified Party within the 15-day period that
it disputes such claim, the Indemnifying Party and the Indemnified Party shall
attempt in good faith for a period of twenty (20) calendar days to settle any
such dispute.

     8.5  Limitations on Indemnification.   No Indemnifying Party shall be
          ------------------------------
obligated to make any payment to an Indemnified Party pursuant to this Section 8
until such time as all claims for indemnification made by such Indemnified Party
pursuant to this Section 8 exceed $20,000 in the aggregate, at which point the
Indemnifying Party shall be obligated to make payment for all claims of such
Indemnified Party pursuant to this Section 8, but only to the extent such
claims, in the aggregate, exceed such initial $20,000 of claims; provided,
                                                                 --------
however, that in no event shall an Indemnifying Party be liable under this
- -------
Section 8 for an amount which is in excess of $4,000,000,  and provided further
that in no event shall the personal liability of each Shareholder under this
Section 8 or otherwise with respect to this Agreement, exceed $2,000,000 each.
Notwithstanding

                                      -23-
<PAGE>

anything to the contrary in this Agreement and except for willful misconduct,
with respect to any domain names other than TextileWeb.com,
Onlinetextilenews.com, Textileshow.com and Nonwovensweb.com, Seller makes no
representations, warranties or covenants other than that it is assigning to
Purchaser all such rights the Seller has in the domain names (other than those
constituting Excluded Assets). Seller Parties shall have no liability or other
responsibility for Purchaser's use of or other actions or omissions with respect
to any such domain names after the Closing.

     8.6  Other Remedies.  The indemnity of this Section 8 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.

defend and indemnify Purchaser against and hold it harmless from any and all
loss, liability, claims, damage or expense (including reasonable attorneys'
fees) arising out of or resulting from such noncompliance, provided that such
loss, liability, claim, damage or expense was not caused by Purchaser's conduct
of the Business or failure to pay the Assumed Liabilities or perform the Assumed
Obligations.

          (b)  The Shareholders shall be permitted to own securities of a public
company not in excess of five percent (5%) of any class of such securities and

transactions contemplated hereby; (ii) the restrictions contained in this

Purchaser, (iii) that the covenants contained in this Section 5.10 are
reasonable as to geographic and temporal scope and that such restrictions are
intended solely to protect the legitimate interests of the Purchaser, rather
than to prevent the Shareholders from earning a livelihood; (iv) that the

<PAGE>

which rights shall be cumulative and in addition to any other rights or remedies
to which the Purchaser may be entitled. In the event that any of the provisions
of this Section 5.10 should ever be adjudicated to exceed the time, geographic,
product or service, or other limitations permitted by applicable law in any
jurisdiction, then such provisions shall be deemed reformed in such jurisdiction
to the maximum time, geographic, product or service, or other limitations
permitted by applicable law.

     5.11  Tax-Free Reorganization.  The parties to this Agreement intend that
           -----------------------
the transactions provided for in this Agreement shall constitute a
reorganization as defined in Section 368(a)(1)(C)  of the Internal Revenue Code
of 1986, as amended, for income tax purposes. Notwithstanding anything to the
contrary in this Agreement nor in any other instrument executed pursuant to this
Agreement, the parties shall not take or make any action that would prevent such
qualification.  Each of the parties shall complete all relevant tax returns
consistent with such qualification and shall not take any positions inconsistent
with such qualification.

     5.12  Liquidation of Seller.  Seller shall take all steps necessary to
           ---------------------
liquidate simultaneously or within the time period thereafter required pursuant
to Section 368(a)(1)(C) of the Internal Revenue Code of 1986, as amended.

6.   Covenants of Purchaser.
     ----------------------

     6.1   Registration Rights.
           -------------------

           (a) Purchaser shall prepare and use its best efforts, and no later
than March 31, 2000 (the "Required Filing Date") to file with the Commission a
registration statement with respect to the resale of the shares received as
Consideration (the "Shares") by the Seller or its permitted assignees (the
"Required Registration Statement") and thereafter shall cause such registration
statement to be declared effective under the Securities Act as promptly as
practicable but in no event later than May 31, 2000 (the "Required Effective
Date"). Purchaser shall file a notification form for the listing of additional
shares to cover the listing of the Shares on the Nasdaq National Market, or such
other market or exchange, if any, on which the Common Stock shall trade.
Purchaser shall use its best efforts to cause the Required Registration
Statement to remain effective for a period of one year. Purchaser acknowledges
that Seller is relying on Purchaser's commitment to cause the Required
Registration Statement to become effective not later than the Required Filing
Date, and agrees that if for any reason the Required Registration Statement is
not declared effective by such date (as it may be extended as herein provided),
even if Purchaser is using its best efforts to cause such effectiveness to be
declared, then Seller shall be entitled to recover damages for any consequential
loss incurred.

           (b) If Purchaser proposes to file a registration statement with
respect to the Common Stock prior to the filing of the Required Registration
Statement, Purchaser shall give prompt notice to the Seller and will include in
such registration (the "Piggyback Registration") subject to the allocation
provisions discussed in Section 6.1(d) and 6.1(e), all Shares with respect

                                      -16-
<PAGE>

to which Purchaser has received written request for inclusion within five (5)
Business Days after such notice is given by Purchaser; provided, however, that
the Seller shall have no Piggyback Registration rights in connection with a
registration statement filed in connection with Purchaser's 5 1/4% Convertible
Subordinated Debentures (the "Convertible Debentures"). No Purchaser
registration statement shall be declared effective unless and until the Required
Registration Statement shall have been declared effective, except for the
registration statement for the Convertible Debentures or if the Required
Registration Statement is not being declared effective due to a comment from the
Commission that relates only to a Seller.

          (c)  Purchaser will pay the expenses related to registration of the
Shares; provided, however, the Seller shall pay any underwriting commissions
related to the registration of the Shares.

          (d)  If a Piggyback Registration is an underwritten primary
registration on behalf of Purchaser and the managing underwriter advises
Purchaser in writing that marketing factors require a limitation on the number
of Shares to be offered and sold, there shall be included in the offering only
that number of Shares, if any, that such managing underwriter reasonably
believes, in its sole discretion, will not jeopardize the success of the
offering.

          (e)  If a Piggyback Registration is initiated as an underwritten
secondary registration on behalf of the holders of the Common Stock, and the
managing underwriters advise Purchaser in writing that marketing factors require
a limitation on the number of Shares to be offered and sold, Purchaser will
allocate the securities to be included as follows: pro rata on the basis of the
number of shares of Common Stock owned among (i) any other Person selling in the
registration and (ii) the Seller.

          (f)  If a Piggyback Registration is underwritten, the Seller shall not
be entitled to select the investment bank(s) or manager(s) nor shall the Seller
be entitled to make decisions regarding the underwriting arrangements for the
offering.

          (g)  If, prior to the Required Filing Date, Purchaser files a
registration statement with the Commission covering shares of its Common Stock
underlying the Convertible Debentures, Purchaser shall, within five (5) Business
Days of such filing, file the Required Registration Statement.

          (h)  Purchaser shall have no obligations under this Section 6.1 until
the Closing Date. If Purchaser files a registration statement covering shares of
its Common Stock underlying the Convertible Debentures prior to the Closing,
Purchaser, shall, within five (5) Business Days after the Closing, file a
registration statement covering the Shares.

7.   Securities Act and Restrictions on Purchaser Stock.
     --------------------------------------------------

     7.1  Purchase Entirely for Own Account. The Seller Parties acknowledge and
          ---------------------------------
agree that the shares of Common Stock of the Purchaser to be received by the
Shareholders as a distribution

                                      -17-
<PAGE>

from the Seller, will be acquired for investment for Shareholder's own account,
not as a nominee or agent, and not with a view to the resale or distribution of
any part thereof, and that Shareholders have no present intention of selling,
granting any participation in, or otherwise distributing the same, but subject
to the ability of Shareholders to distribute Shareholders assets (including the
Consideration) to Shareholders affiliates (as such term is defined in Section
144 of the Securities Act).

     7.2  Investment Experience.  The Shareholders represent and warrant that
          ---------------------
Shareholders can bear the economic risk of an investment in Common Stock of the
Purchaser acquired pursuant to this Agreement and have such knowledge and
experience in financial or business matters that Shareholders are capable to
protect Shareholder's own interests in connection with the acquisition of Common
Stock of the Purchaser.

     7.3  Information Supplied.  Shareholders represent and warrant that
          --------------------
Shareholders have had an adequate opportunity to ask questions and receive
answers from the officers of Purchaser concerning the terms and conditions of
the transaction contemplated by this Agreement and the shares of Common Stock of
the Purchaser to be issued in connection therewith. Shareholders represent and
warrant that Shareholders have asked any and all questions that Shareholders may
have in the nature described in the preceding sentence and that all such
questions have been answered to Shareholder's satisfaction. Shareholders
represent and warrant that Shareholders have reviewed the SEC Documents and that
Shareholders have had adequate opportunity to ask questions of and has received
answers to Shareholder's satisfaction from the officers of Purchaser concerning
the matters described therein.

     7.4  Restricted Securities. Shareholders understand that the shares of
          ---------------------
Common Stock of the Purchaser to be received by Shareholders are characterized
as "restricted securities" under the federal securities laws inasmuch as they
are being acquired from Purchaser in a transaction not involving a public
offering and that under such laws and applicable regulations such securities may
not be resold without registration under the Securities Act, except in certain
limited circumstances.  In this connection, Shareholders represent that
Shareholders are familiar with Rule 144 under the Securities Act, as presently
in effect, and understands the resale limitations imposed thereby and by the
Securities Act.

     7.5  Further Limitations on Disposition.  Without in any way limiting the
          ----------------------------------
representations set forth above, Shareholders further agree not to make any
disposition of all or any portion of the shares representing the Stock
Consideration except to Shareholder's affiliates unless and until:

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

          (b)  Shareholders shall have notified Purchaser of the proposed
disposition and shall have furnished Purchaser with a detailed statement of the
circumstances surrounding the proposed disposition, and if reasonably requested
by Purchaser, Shareholders shall have furnished

                                      -18-
<PAGE>

Purchaser with an opinion of counsel, reasonably satisfactory to Purchaser, that
such disposition will not require registration of such shares under the
Securities Act. It is agreed that Purchaser will not require opinions of counsel
for transactions made pursuant to Rule 144 by Shareholders except in unusual
circumstances.

Notwithstanding the provisions of paragraphs (a) and (b) above, no such
registration statement or opinion of counsel shall be necessary for a transfer
by Shareholders (i) to an affiliate of Shareholders, or the transfer by gift,
will or intestate succession to Shareholder's spouse or lineal descendants or
ancestors, if the transferee agrees in writing to be subject to the terms of
this Section 7 to the same extent as if he or she were Shareholders, or (ii) at
any time after the provisions of subparagraph (k) of Rule 144 are applicable to
Shareholders.

     7.6  Legends.  It is understood that the certificates evidencing the
          -------
Consideration may bear the following legend:

          "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR
          ANY STATE SECURITIES OR BLUE SKY LAWS. THEY MAY NOT BE SOLD,
          OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF
          A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE
          SECURITIES UNDER THE SECURITIES ACT AND ANY APPLICABLE STATE
          SECURITIES AND BLUE SKY LAWS OR AN OPINION OF COUNSEL
          SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT
          REQUIRED OR UNLESS SOLD PURSUANT TO RULE 144 OF THE
          SECURITIES ACT."

     7.7  Reporting Requirements.  Purchaser covenants and agrees that it shall
          ----------------------
remain current with respect to all SEC reporting requirements to which Purchaser
is subject.

     8.4  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, and in any case within seven (7) calendar days, 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.

          (a)  The Indemnifying Party shall have thirty (30) calendar 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.

          (b)  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

                                      -21-
<PAGE>

Party, which consent shall not be unreasonably withheld; 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.

          (c)  If the Indemnifying Party shall fail to so elect to defend or
settle such claim (exercising reasonable business judgment) at its own expense,
within thirty (30) calendar 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 Indemnified Party.

          (d)  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 fifteen (15)
calendar days after delivery thereof to elect, in writing to the Indemnified
Party, to settle the claim at its own expense. If the Indemnifying Party (i)
does not notify the Indemnified Party within fifteen (15) calendar days after
the Indemnified Party's notice that it disputes such claim or (ii) notifies the
Indemnified Party that it does not dispute such claim, the amount of such claim
shall be conclusively deemed as a liability of the Indemnifying Party. If the
Indemnifying Party notifies the Indemnified Party within the 15-day period that
it disputes such claim, the Indemnifying Party and the Indemnified Party shall
attempt in good faith for a period of twenty (20) calendar days to settle any
such dispute.

     8.5  Limitations on Indemnification.   No Indemnifying Party shall be
          ------------------------------
obligated to make any payment to an Indemnified Party pursuant to this Section 8
until such time as all claims for indemnification made by such Indemnified Party
pursuant to this Section 8 exceed $20,000 in the aggregate, at which point the
Indemnifying Party shall be obligated to make payment for all claims of such
Indemnified Party pursuant to this Section 8, but only to the extent such
claims, in the aggregate, exceed such initial $20,000 of claims; provided,
                                                                 --------
however, that in no event shall an Indemnifying Party be liable under this
- -------
Section 8 for an amount which is in excess of the Purchase Price in the
aggregate.

     8.6  Other Remedies. The indemnity of this Section 8 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.
