     The following summary is qualified in its entirety by the more detailed
information appearing elsewhere in this prospectus or incorporated by reference
in this prospectus and may not contain all the information that is important to
you.

                                   Our Company

     Verticalnet, Inc. is a leading provider of software to businesses to help
them address challenges in doing business with their suppliers and customers.
Our software helps businesses to buy goods more efficiently from their
suppliers, to plan more effectively with both their suppliers and their
customers, and to track and manage optimally customer orders back through the
supply chain to all the purchases they must make from their suppliers to meet
customer orders. We license our software to customers and offer them maintenance
and professional services.

     We designed our software to support not just our customer, but also our
customer's suppliers and customers. Our software works outside the enterprise,
along with our customer's existing technology systems that are installed to work
inside the enterprise. Our customer and its suppliers and customers are all able
to access our software through the Internet. Once a customer installs our
software, all of its customers and suppliers can share information jointly with
our customer through the Internet without having to install anything at their
locations.

                               Recent Developments

         On February 19, 2002, we announced our intention to sell the
Small/Medium Business unit, which provides marketplace solutions that connect
buyers and suppliers online through 59 industry-specific marketplaces. Our board
of directors authorized this action to complete our strategic realignment to an
enterprise software business. SMB unit revenues for the fourth quarter ending
December 31, 2001 were $16.6 million, compared to $34.6 million for the fourth
quarter of the previous year. SMB unit revenues for the fiscal year ending
December 31, 2001 were $90.0 million, compared to $104.5 million for the
previous year. Beginning in the first quarter of 2002, we will exclude the SMB
unit from our results from continuing operations.


                                       1





                                  RISK FACTORS

RISKS RELATED TO OUR CONTINUING OPERATIONS.

         WE MAY REQUIRE ADDITIONAL CAPITAL FOR OUR OPERATIONS AND OBLIGATIONS,
WHICH WE MAY NOT BE ABLE TO RAISE OR, EVEN IF WE DO, COULD BE DILUTIVE TO OUR
SHAREHOLDERS.

         Although, based on our most recent projections, we believe our current
level of liquid assets and the expected cash flows from contractual arrangements
will be sufficient to finance our capital requirements and anticipated operating
losses for at least the next 12 months, any projection of future long-term cash
needs and cash flows are inherently subject to uncertainty. There is no
assurance that our resources will be sufficient for anticipated or unanticipated
working capital and capital expenditure requirements during this period. We may
need, or find it advantageous, to raise additional funds in the future to fund
our growth, pursue sales and licensing opportunities, develop new or enhanced
products and services, respond to competitive pressures or acquire complementary
businesses, technologies or services.

         If we are ultimately unable, for any reason, to receive cash payments
expected from our customers, in particular scheduled payments from Converge, our
business, financial condition and results of operations will be materially and
adversely affected. We also have a 15.4 million Euro (approximately $13.6
million as of December 31, 2001) put and call agreement with British
Telecommunications whereby BT has the right to sell its remaining investment in
Verticalnet Europe to us in March 2002. Our ability to use our stock to pay this
obligation may be limited by our stock price and trading volume, so we may have
to use cash to satisfy some or substantially all of this obligation, which could
increase our need to obtain additional financing.

         If we raise additional funds through the issuance of equity or
convertible debt securities, the percentage ownership of our shareholders will
be reduced and shareholders will experience additional dilution. These new
securities may also 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 operations adequately, promote our brand identity, take advantage of
acquisition opportunities, develop or enhance products or services or respond to
competitive pressures. Any inability to do so could have a negative effect on
our business, financial condition and results of operations.

         WE MAY NEVER GENERATE AN OPERATING PROFIT.

         As of December 31, 2001, our accumulated deficit was approximately $1.1
billion. For the year ended December 31, 2001, we sustained a $768.3 million
loss attributable to common shareholders (including preferred stock dividends).
We expect to incur operating losses for the foreseeable future. We may never
generate an operating profit or, even if we do become profitable from operations
at some point, we may be unable to sustain that profitability.

         WE MAY NOT DEVELOP SIGNIFICANT REVENUES FROM ENTERPRISE SOFTWARE
LICENSING AND PROFESSIONAL SERVICES, WHICH COULD ADVERSELY AFFECT OUR FUTURE
REVENUE GROWTH AND ABILITY TO ACHIEVE PROFITABILITY.

         If we do not develop and consistently generate significant revenues
from enterprise software licensing and professional services, our business,
financial condition and operating results will be impaired. Our ability to
generate software revenues depends on the overall demand for enterprise software
solutions and professional services, as well as general economic and business
conditions. Suppressed demand for software solutions and services caused by a
weakening economy and reduced levels of spending on technology solutions may
result in less revenue growth than expected or even a decline in revenues. We
cannot offer any assurances that we will be able to develop, enhance or promote
our enterprise software solutions and professional services effectively, whether
as a result of general economic conditions or otherwise.



                                       2


         IF WE CANNOT FURTHER REDUCE OUR EXPENSES, OUR OPERATING RESULTS WILL
SUFFER.

         Our expense reductions and layoffs throughout 2001 may not have
sufficiently reduced our ongoing operating expenses to a level necessary to
achieve operating profits. If we cannot further reduce our expenses, some of
which are fixed, including those related to non-cancelable agreements, equipment
leases and real estate leases, then our operating results will suffer. In
addition, we may not be successful in further identifying and eliminating
redundancies within our business, or in streamlining our overall operations as
necessary to reduce our expenses.

         FLUCTUATIONS IN OUR QUARTERLY OPERATING RESULTS MAY CAUSE OUR STOCK
PRICE TO DECLINE.

         Our quarterly operating results are difficult to forecast and could
vary significantly. We believe that period-to-period comparisons of our
operating results are not meaningful and should not be relied on as indicators
of future performance. If our operating results in a future quarter or quarters
do not meet the expectations of securities analysts or investors, the price of
our common stock may fall. Our quarterly operating results will be substantially
dependent on software licenses booked and delivered in that quarter. Any delay
in the recognition of revenue for any of our license transactions could cause
significant variations in our quarterly operating results and could cause our
revenues to fall significantly short of anticipated levels. We also expect that
our quarterly operating results will fluctuate significantly due to other
factors, many of which are beyond our control, including:

         o        anticipated lengthy sales cycles for our products;

         o        the size and timing of individual license transactions;

         o        intense and increased competition in our target markets;

         o        our ability to develop, introduce and bring to market new
                  products and services, or enhancements to our existing
                  products and services, on a timelyo basis; and

         o        risks associated with past and future acquisitions.

         WE MAY BE UNABLE TO MAINTAIN OUR LISTING ON THE NASDAQ NATIONAL MARKET,
WHICH COULD CAUSE OUR STOCK PRICE TO FALL AND DECREASE THE LIQUIDITY OF OUR
COMMON STOCK.

         Our common stock is currently listed on the Nasdaq National Market,
which has requirements for the continued listing of stock. One of the continued
listing requirements is that our common stock maintain a minimum bid price of
$1.00 per share. Since August 2001, the bid price for our common stock has
dropped below $1.00 during extended periods. If our common stock trades below
$1.00 for 30 consecutive trading days, or if we fail to meet any of the other
listing requirements, our common stock may be delisted from the Nasdaq National
Market and the trading market for our common stock could decline, which could
depress our stock price and adversely affect the liquidity of our common stock.

         WE ANTICIPATE LENGTHY SALES AND IMPLEMENTATION CYCLES FOR OUR SOFTWARE
PRODUCTS.

         We anticipate the sales cycles for our enterprise software products to
average approximately six to nine months. In selling our products, we may be
asking potential customers in many cases to change their established business
practices and conduct business in new ways. In addition, potential customers
must generally consider additional issues, such as product benefits, ease of
installation, ability to work with existing technology, functionality and
reliability, before committing to purchase our products. Additionally, we
believe that the purchase of our products is often discretionary and generally
involves a significant commitment of capital and other resources by a customer,
which frequently requires approval at a number of management levels within the
customer organization. Likewise, the implementation and deployment of our
enterprise software products requires a significant commitment of resources by
our customers and our professional services organization. The challenges we face
in attempting to obtain commitments and approvals from our customers may be
exacerbated by worsening economic conditions in general and in our target
markets, as well as by competition from other software solution providers whose
brands, products and services may be better known to, and more widely accepted
by, potential customers than ours.


                                       3


         WE EXPECT TO RELY ON THIRD PARTIES TO IMPLEMENT OUR PRODUCTS.

         We expect to rely increasingly on third parties to implement our
software products at customer sites. If we are unable to establish and maintain
effective, long-term relationships with implementation providers, or if these
providers do not meet the needs or expectations of our customers, our business
could be seriously harmed. As a result of the limited resources and capacities
of many third-party implementation providers, we may be unable to establish or
maintain relationships with third parties having sufficient resources to provide
the necessary implementation services to support our needs. If these resources
are unavailable, we will be required to provide these services internally, which
could significantly limit our ability to meet our customers' implementation
needs. A number of our competitors have significantly more well-established
relationships with third parties that we may potentially partner with. As a
result, these third parties may be more likely to recommend competitors products
and services rather than our own. In addition, we would not be able to control
the level and quality of service provided by our implementation partners.

         NEW VERSIONS AND RELEASES OF OUR PRODUCTS MAY CONTAIN ERRORS OR
DEFECTS.

         Our enterprise software products may contain undetected errors or
failures when first introduced or as new versions are released. This may result
in loss of, or delay in, market acceptance of our products. Errors in new
releases and new products after their introduction could result in delays in
release, lost revenues and customer frustration during the period required to
correct these errors. We may in the future discover errors and defects in new
releases or new products after they are shipped or released.

         OUR TARGET MARKETS ARE EVOLVING AND CHARACTERIZED BY RAPID
TECHNOLOGICAL CHANGE, WHICH WE MAY NOT BE ABLE TO KEEP PACE WITH.

         The markets for our products and services are evolving and
characterized by rapid technological change, changing customer needs, evolving
industry standards and frequent new product and service announcements. The
introduction of products employing new technologies and emerging industry
standards could render our existing products or services obsolete or
unmarketable. If we are unable to respond to these developments successfully or
do not respond in a cost-effective way, our business, financial condition and
operating results will suffer. To be successful, we must continually improve and
enhance the responsiveness, services and features of our enterprise software
products and introduce and deliver new product and service offerings and new
releases of existing products. We may fail to improve or enhance our software
products or introduce and deliver new releases or new offerings on a timely and
cost-effective basis or at all. If we experience delays in the future with
respect to our software products, or if our improvements, enhancements,
offerings or releases to these products do not achieve market acceptance, we
could experience a delay or loss of revenues and customer dissatisfaction. Our
success will also depend in part on our ability to acquire or license third
party technologies that are useful in our business, which we may not be able to
do.

         WE MAY ULTIMATELY BE UNABLE TO COMPETE IN THE MARKETS FOR THE PRODUCTS
AND SERVICES WE OFFER.

         The markets for our software products and services are intensely
competitive, which may result in low or negative profit margins and difficulty
in achieving market share, either of which could seriously harm our business. We
expect the intensity of competition to remain intense and to increase. Our
enterprise software products and services face competition from software
companies whose products or services compete with a particular aspect of the
solution we provide, as well as several major enterprise software developers.
Many of our competitors have longer operating histories, greater brand
recognition and greater financial, technical, marketing and other resources than
we do, 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
products or services that are superior to or have greater market acceptance than
ours. If we are unable to compete successfully against our competitors, our
business, financial condition and operating results would be negatively
impacted.



                                       4


         WE ARE EXPOSED TO RISKS ASSOCIATED WITH DECREASES IN THE FAIR VALUE, OR
A COMPLETE LOSS, OF OUR EQUITY INVESTMENTS.

         We may invest in equity instruments of privately-held companies for
business and strategic purposes. Such items are included in other investments on
our balance sheet. As of December 31, 2001, we held cost method investments of
$10.6 million, of which our Converge investment was $7.8 million. We may never
realize any return on our equity interests in Converge or these other entities,
or we may suffer a complete loss of these equity interests, which could
materially and adversely affect our business, financial condition and operating
results. In addition, our quarterly results may be materially reduced if we
determine that an impairment in the fair value of one of our equity positions is
other than temporary, which would require us to write down or write off the
carrying value of those securities. During the year ended December 31, 2001, we
recorded an aggregate of $231.3 million in impairment charges for other than
temporary declines in the fair value of several of our cost method, equity
method and available-for-sale investments, $207.2 million of which was a
write-down of the fair value of our investment in Converge.

         ACQUISITIONS MAY NEGATIVELY IMPACT OUR BUSINESS.

         We have grown, and may continue to grow, our business through
acquisitions that complement our existing products and services. If we are
unable to complete future acquisitions, our business, financial condition and
operating results could be negatively impacted. We may not be able to identify
additional suitable businesses that are available for sale at reasonable prices
or on reasonable terms. Even if we are able to identify appropriate acquisition
candidates, we may not be able to negotiate the terms of any acquisition
successfully, finance the acquisition or integrate the acquired business
(including its products, services, technologies or personnel) into our existing
business operations. Our acquisition strategy is also subject to numerous other
risks including, without limitation, the following:

         o        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;

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

         o        we may not be able to retain key employees from acquired
                  companies or from our own company after the acquisition, and
                  may face competition from employees that leave before or after
                  an acquisition is complete;

         o        to pay for acquisitions, we may be required to issue equity
                  securities, which may be dilutive to existing shareholders, or
                  we may be required to incur debt or spend cash, which would
                  negatively impact our liquidity and could impair our ability
                  to fund our operations;

         o        we may not realize any return on our investment in the
                  acquired companies and may even lose our entire investment and
                  incur significant additional losses;

         o        our share price could decline following market reaction to our
                  acquisitions; and

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

         IF WE DO NOT DEVELOP THE "VERTICALNET" BRAND IN THE ENTERPRISE SOFTWARE
INDUSTRY, OUR REVENUES MIGHT NOT INCREASE.

         To be successful, we must establish and continuously strengthen the
awareness of the "Verticalnet" brand in the enterprise software industry. If our
brand awareness as a maker of enterprise software does not develop, or if
developed, is not sustained as a respected brand, it could decrease the
attractiveness of our products and services to potential customers, which could
result in decreased revenues.



                                       5


         OUR INTERESTS MAY CONFLICT WITH THOSE OF INTERNET CAPITAL GROUP, OUR
LARGEST SHAREHOLDER, WHICH MAY AFFECT OUR BUSINESS STRATEGY AND OPERATIONS
NEGATIVELY.

         As a result of its stock ownership and board representation, Internet
Capital Group is in a position to 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, 2001, Internet Capital Group beneficially owned 25,318,644 shares, or
approximately 22.3%, of our common stock, which includes 250,000 shares of our
common stock underlying $5.0 million of our 5 1/4% convertible subordinated
debt, and 478,624 shares of our common stock underlying warrants issued to
Internet Capital Group prior to our initial public offering. One representative
of Internet Capital Group is a member of our board of directors. We may compete
with Internet Capital Group for Internet-related opportunities as it seeks to
expand its number of business-to-business assets, in part through acquisitions
and investments. Internet Capital Group, therefore, may seek to acquire or
invest in companies that we would find attractive. While we may partner with
Internet Capital Group on future acquisitions or investments, we have no current
contractual obligations to do so. We do not have any contracts or other
understandings that would govern resolution of this potential conflict. This
competition, and the potential conflict posed by the designated director, may
deter companies from partnering with us and may limit our business
opportunities.

         INTERNET CAPITAL GROUP MAY HAVE TO BUY OR SELL OUR STOCK TO AVOID
REGISTRATION UNDER THE INVESTMENT COMPANY ACT OF 1940, WHICH MAY NEGATIVELY
AFFECT OUR STOCK PRICE.

         To avoid registration under the Investment Company Act of 1940,
Internet Capital Group may need to continue to own more than 25% of our voting
securities and to continue to have a representative on our board of directors.
Under the Investment Company Act, a company is considered to control another
company if it owns more than 25% of that company's voting securities and is the
largest stockholder of such company. A company may be required to register as an
investment company if more than 45% of its total assets consist of, and more
than 45% of its income/loss and revenue attributable to it over the last four
quarters is derived from, ownership interests in companies it does not control.
Internet Capital Group has publicly stated that it is not feasible to be
regulated as an investment company because the Investment Company Act rules are
inconsistent with their corporate strategy. As of December 31, 2001, Internet
Capital Group's ownership interest in us was 22.3%. Because its ownership
interest has fallen below 25%, Internet Capital Group may need to purchase
additional voting securities to return to an ownership interest of at least 25%
to avoid having to register as an investment company. The possible need of
Internet Capital Group to maintain a 25% ownership position could adversely
influence its decisions regarding actions that may otherwise be in the best
interests of our public shareholders. If Internet Capital Group sells all or
part of its investment in us, whether to comply with the Investment Company Act
of 1940, to raise additional capital or otherwise, it could adversely affect our
common stock's market price.

         OUR SUCCESS DEPENDS ON OUR KEY MANAGEMENT AND EXPERIENCED SOFTWARE
PERSONNEL, WHOM WE MAY NOT BE ABLE TO RETAIN OR HIRE.

         We believe that our success depends on continued employment of our
senior management team and on having a highly trained product development staff,
sales force and professional service organization. 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. If we are unable to retain or hire trained
technical personnel and experienced software sales and service professionals, it
could limit our ability to design, develop and implement our products, or
increase sales of our products and services. Ultimately, our business, financial
condition and operating results will be impaired if we cannot hire and retain
suitable personnel.

         WE MAY NOT BE ABLE TO PROTECT OUR PROPRIETARY RIGHTS AND MAY INFRINGE
THE PROPRIETARY RIGHTS OF OTHERS.

         Proprietary rights are important to our success and our competitive
position. We may be unable to register, maintain and protect our proprietary
rights adequately or to prevent others from claiming violations of their
proprietary rights. Although we file copyright registrations for the source code
underlying our software, enforcement of our rights might be too difficult and
costly for us to pursue effectively. We have filed patent applications for the
proprietary technology underlying our software, but our ability to fully protect
this technology is contingent upon



                                       6


the ultimate issuance of the corresponding patents. Effective patent, copyright
and trade secret protection of our software may be unavailable or limited in
certain countries.

         SEVERAL LAWSUITS HAVE BEEN BROUGHT AGAINST US AND THE OUTCOME OF THESE
LAWSUITS IS UNCERTAIN.

         Several lawsuits have been brought against us and the underwriters of
our stock in our initial public offering. These lawsuits allege, among other
things, that the underwriters engaged in sales practices that had the effect of
inflating our stock price, and that our prospectus for that offering was
materially misleading because it did not disclose these sales practices. We
intend to vigorously defend against these lawsuits. No assurance can be given as
to the outcome of these lawsuits.

         WE MAY NOT HAVE SUFFICIENT CASH FLOW FROM OPERATIONS TO SERVICE OUR
DEBT.

         As of December 31, 2001, we had approximately $24.9 million in
long-term debt (including $21.7 million of our outstanding 5 1/4% convertible
subordinated debentures due 2004). Currently, we are not generating sufficient
cash flow from our operations to satisfy our annual debt service payment
obligations. If we are unable to satisfy our debt service requirements,
substantial liquidity problems could result, which would negatively impact our
future prospects.

         SHARES ELIGIBLE FOR FUTURE SALE BY OUR CURRENT OR FUTURE SHAREHOLDERS
MAY CAUSE OUR STOCK PRICE TO DECLINE.

         If our shareholders or optionholders sell substantial amounts of our
common stock in the public market, including shares issued in completed or
future acquisitions or upon the exercise of outstanding options and warrants,
then the market price of our common stock could fall. As of December 31, 2001,
the holders of 41,511,038 shares of common stock (which includes the 14,157,630
shares issued in the acquisition of Atlas Commerce), warrants to purchase
2,127,038 shares of common stock and 107,675 shares of Series A preferred stock,
which are convertible into approximately 1,239,428 shares of common stock, have
demand and/or piggyback registration rights. The exercise of such rights could
adversely affect the market price of our common stock. We also have filed a
shelf registration statement to facilitate our acquisition strategy, as well as
registration statements to register shares of common stock under our stock
option and employee stock purchase plans. Shares issued pursuant to existing or
future shelf registration statements, upon exercise of stock options and in
connection with our employee stock purchase plan 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 for stocks of technology companies has been highly volatile
since our initial public offering in 1999. Throughout this period, the market
price of our common stock has reached extreme highs and lows, and our daily
trading volume has been, and will likely continue to be, highly volatile.
Investors may not be able to resell their shares of our common stock following
periods of price or trading volume volatility because of the market's adverse
reaction to such volatility. Factors that could cause volatility in our stock,
in some cases regardless of our operating performance, include, among other
things:

         o        general economic conditions, including suppressed demand for
                  technology products and services;

         o        actual or anticipated variations in quarterly operating
                  results;


                                       7


         o        announcements of technological innovations;

         o        new products or services;

         o        changes in financial estimates by securities analysts;

         o        conditions or trends in business-to-business usage of software
                  and related technology;

         o        changes in the market valuations of other Internet, software
                  or technology companies;

         o        failure to meet analysts' or investors' expectations;

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

         o        capital commitments;

         o        additions or departures of key personnel; and

         o        sales of common stock or instruments convertible into common
                  stock.

RISKS RELATED TO OUR SMALL/MEDIUM BUSINESS UNIT THAT WE INTEND TO SELL, WHICH
THEREFORE WILL BE TREATED FOR ACCOUNTING PURPOSES AS DISCONTINUED OPERATIONS
AFTER 2001.

         THE REVENUES AND OPERATING RESULTS OF OUR SMB UNIT WILL NO LONGER BE
REPORTED IN THE RESULTS FROM CONTINUING OPERATIONS BEGINNING IN THE FIRST
QUARTER OF 2002.

         For the year ended December 31, 2001, $90.0, or approximately 72% of
our overall revenues were generated primarily from sales of storefronts,
marketplace managers and advertising on our SMB unit's industry marketplaces.
Because the SMB unit will be treated as a discontinued operation, we will not
report future revenues from the SMB unit as part of our continuing operations.
As a result of our decision to sell the SMB unit, we anticipate that the
composition of our reported revenues will change substantially in future
periods. Beginning in 2002, we will be increasingly dependent on generating
revenues from enterprise software licensing and professional services. In the
foreseeable future, we may not be able to generate revenues from our continuing
operations at the levels we did when we included the revenues of the SMB unit in
our continuing operations.

         IF THE BUSINESS, REVENUES AND OPERATING RESULTS OF OUR SMB UNIT DECLINE
PRIOR TO A SALE OF THAT BUSINESS, IT COULD DELAY OR IMPEDE OUR ABILITY TO SELL
THE SMB UNIT, WHICH WOULD NEGATIVELY IMPACT OUR CASH FLOW AND INCREASE OUR NET
LOSS.

         We announced on February 13, 2002, that we intend to sell the SMB unit
and will treat it for accounting purposes as a discontinued operation in the
first quarter of 2002, based on our expectation that we will sell that business
within a reasonable period of time. Although the results of operations of the
SMB unit will not be included in our operating results after 2001 until we
complete a sale of the business, we will report the net loss from the SMB unit
as discontinued operations on a quarterly basis in determining our total net
loss, and we will continue to fund any net cash used in the SMB unit. If the
financial performance of the SMB unit declines, then it could be more difficult
for us to sell the SMB unit at an acceptable purchase price, or it could
significantly delay our ability to complete a sale. If we continue to own the
SMB unit for an extended time period during which its financial performance
declines significantly or it has significant unexpected cash needs, then our
total net loss and cash flows could be negatively impacted.

         Our SMB unit faces the following risk factors in connection with its
business.



                                       8


         IF WE ARE UNABLE TO PROVIDE NEW CUSTOMER LEADS TO THE SUPPLIERS, BUYERS
AND OTHER USERS OF OUR INDUSTRY MARKETPLACES, IT MAY NEGATIVELY IMPACT THE
OPERATING RESULTS OF OUR SMB UNIT.

         The success of our SMB unit depends on our ability to provide sales
leads to the suppliers, buyers and other users of our industry marketplaces. If
we are unable to attract buyers to visit our industry marketplaces then they
will be unlikely to leave sales leads for our suppliers. If we are unable to
consistently provide sales leads to suppliers, they will be unlikely to purchase
or renew our marketplace manager tools. If suppliers have an unsatisfactory
experience receiving sales leads, we would have difficulty in cross-marketing to
them to leave sales leads in buying for their own businesses from other
suppliers. If the sales leads that suppliers do receive are of such poor quality
that they consistently fail to result in sales, then they will be unlikely to
purchase or renew our marketplace manager tools.

         THE SUCCESS OF OUR SMB UNIT DEPENDS ON THE DEVELOPMENT OF ALLIANCES
WITH THIRD-PARTY MARKETPLACES TO DRIVE ADDITIONAL LEADS TO OUR SUPPLIERS, WHICH
IS UNCERTAIN.

         The success of the SMB unit depends in part upon our ability to drive
more leads to our suppliers by syndicating our suppliers' content into industry
marketplaces maintained by other parties. We expect to rely increasingly on
alliances with third-party marketplaces to syndicate our suppliers' content into
other industry marketplaces. Our failure to maintain relationships and build new
ones with third-party industry marketplaces. could result in our failure to
provide leads to our suppliers.

         IF WE CANNOT GENERATE NEW REVENUES FROM THE SALE OF MARKETPLACE MANAGER
PRODUCTS, THEN OUR SMB BUSINESS WOULD SUFFER.

         Our SMB unit currently relies for a material part of its revenues on
the sale of our marketplace manager tool, which helps customers generate sales
leads on our industry marketplaces. If we are not able to increase our level of
new revenues from marketplace manager sales, our SMB business may suffer. Our
ability to increase our new sales or renewals of our marketplace manager tools
depends on many factors, including, without limitation:

         o        general economic conditions and their impact on demand for
                  online sales tools;

         o        acceptance of the Internet as a legitimate, effective and
                  measurable medium for business-to-business activity;

         o        the development of a large base of users on our industry
                  marketplaces who possess demographic characteristics
                  attractive to suppliers; and

         o        our ability to develop effective marketing programs and build
                  relationships with third-party providers to help generate
                  sales leads.

         THE CONTENT ON OUR SMB UNIT INDUSTRY MARKETPLACES MAY NOT ATTRACT A
SIGNIFICANT NUMBER OF USERS WITH DEMOGRAPHIC CHARACTERISTICS VALUABLE TO
SUPPLIERS.

         The future success of the SMB unit depends in part upon our ability to
deliver compelling business content on our industry marketplaces that will
attract a significant number of buyers and other users with demographic
characteristics valuable to business suppliers. Our inability to deliver
business content that attracts a loyal buyer base with demographic
characteristics attractive to suppliers could impair the business, financial
condition and operating results of the SMB unit. We face the challenge of
delivering content that is attractive to users in an environment characterized
by rapidly changing user preferences, as well as the ease with which users can
freely navigate and instantly switch among a large number of Internet sites,
many of which offer business content that may be more attractive than ours. If
we cannot consistently anticipate or respond quickly to changes in user
preferences or distinguish our content from that offered on other Web sites, our
SMB unit industry marketplaces may not attract a significant number of users
with demographic characteristics that buyers and suppliers are seeking.


                                       9


         WE MAY NOT BE ABLE TO PROTECT THE PROPRIETARY RIGHTS OF OUR SMB UNIT
AND MAY INFRINGE THE PROPRIETARY RIGHTS OF OTHERS.

         Generally, our domain names for our SMB unit industry marketplaces
cannot be protected as trademarks because they are considered "generic" under
applicable law. In addition, effective copyright, trademark, patent and trade
secret protection may be unavailable 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 for our
industry marketplaces, which makes it possible that we could become subject to
infringement actions based upon the content licensed from those third parties.

         OUR FAILURE TO MAINTAIN RELATIONSHIPS WITH THIRD-PARTY CONTENT
PROVIDERS MAY IMPAIR THE OPERATING RESULTS OF OUR SMB UNIT.

         We have relied on, and expect to rely increasingly on, third parties
such as news wires to provide content for our industry marketplaces. If we are
unable to maintain our relationships with third-party content providers, or
replace them with other content providers on comparable terms, then we could
suffer decreased traffic on, and customer leads through, our industry
marketplaces.

         WE MAY BE SUBJECT TO LEGAL LIABILITY FOR PUBLISHING OR DISTRIBUTING
CONTENT ON OUR INDUSTRY MARKETPLACES OVER THE INTERNET.

         Providers of Internet products and services have been sued in the past,
sometimes successfully, based on the content they offer. We may be subject to
legal claims relating to the content on our industry marketplaces, or the
downloading and distribution of such content. Claims could also involve matters
such as defamation, invasion of privacy and copyright infringement. In addition,
some of the content provided on our industry marketplaces 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 SMB unit's business, financial condition and operating results
could suffer materially if costs resulting from these claims are not covered by
our insurance or exceed our coverage.

                           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.

     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 guaranteed. 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 1
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.

                              SELLING SHAREHOLDERS

     Verticalnet issued the shares of common stock in connection with the
acquisition of Atlas Commerce, Inc. Such transaction was 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. None of the selling
shareholders has had a material relationship with Verticalnet within the past
three years other than as a result of the ownership of our shares or other
securities.

     The following table sets forth information, as of December 28, 2001, with
respect to each selling shareholder. 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 completion of this offering. 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.

                              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. The common stock may be sold by one or more of, or a
combination of, the following:

     o    a block trade in which the broker-dealer so engaged will attempt to
          sell the shares as agent but may position and resell a portion of the
          block as principal to facilitate the transaction;

     o    purchases by a broker-dealer as principal and resale by such
          broker-dealer for its account pursuant to this prospectus;

     o    an exchange distribution in accordance with the rules of such
          exchange;

     o    ordinary brokerage transactions and transactions in which the broker
          solicits purchasers; and

     o    in privately negotiated transactions.

     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



                                       13


may not be sold unless it has 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 of 1933. Any discounts,
commissions, concessions or profit they earn on any resale of the shares may be
underwriting discounts and commissions under the Securities Act of 1933. Selling
shareholders who are "underwriters" within the meaning of Section 2(11) of the
Securities Act of 1933 will be subject to the prospectus delivery requirements
of the Securities Act of 1933. The selling shareholders have acknowledged that
they understand their obligations to comply with the provisions of the
Securities Exchange Act of 1934 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 provisions.

     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 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.

                                  LEGAL MATTERS

     The validity of the securities offered by this prospectus will be passed
upon for us by our general counsel, James W. McKenzie, Jr.

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
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.



                                       17


     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.


                                       18



         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 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.
