    YOU SHOULD READ THE FOLLOWING SUMMARY TOGETHER WITH THE MORE DETAILED
INFORMATION AND OUR FINANCIAL STATEMENTS AND THE NOTES TO THOSE STATEMENTS
APPEARING ELSEWHERE IN THIS PROSPECTUS.

                                  TRADEOUT.COM

    TradeOut.com is a leading business-to-business Internet marketplace for
buyers and sellers of excess inventory and idle assets, known as business
surplus. Our solution creates a more efficient way to buy and sell business
surplus by centralizing the fragmented market and streamlining the traditionally
cumbersome fax- and paper-based sales and procurement process. Our
Internet-based solution enables businesses to buy and sell business surplus
globally, across a variety of industries, 24 hours a day, seven days a week.

    Through December 31, 1999, 230 companies had sold more than $15 million
worth of excess inventory and idle assets to 359 businesses through our
marketplace. As of December 31, 1999, approximately $979 million of business
surplus was posted for sale on our Web site. Business users from 43 different
countries posted more than 8,400 items for sale on our marketplace between April
1999, when we launched our Web site, and December 31, 1999. Today, our
marketplace contains business surplus in more than 100 different product
categories.

                             OUR MARKET OPPORTUNITY

    Most companies create business surplus in the ordinary course of business as
a result of many events, including the discontinuation of products, customer
returns, equipment upgrades and the expiration of leases. We estimate that the
worldwide market for business surplus in 1999 totaled more than $400 billion.
Businesses incur costs associated with storing, tracking and maintaining this
business surplus and therefore seek efficient means of disposing of it. However,
the traditional methods of selling business surplus can be difficult, time
consuming and expensive, deterring many businesses from undertaking the selling
process. The Internet enables the creation of centralized marketplaces that
allow widely dispersed buyers and sellers to interact and facilitate the
efficient exchange of product and pricing information.

                                  OUR SOLUTION

    TradeOut.com harnesses the power of the Internet to reduce the
inefficiencies inherent in the traditional process of buying and selling
business surplus. TradeOut.com provides a centralized marketplace that brings
together buyers and sellers of business surplus. We allow sellers to quickly and
easily disseminate information about their business surplus over the Internet
directly to prospective buyers. We centralize relevant industry, product and
pricing information on our marketplace and allow it to be easily updated,
organized and searched. The auction formats we offer provide a competitive
environment for establishing optimal pricing for sellers. Our marketplace
streamlines the buying process and reduces transaction costs associated with
traditional purchasing methods.

    We focus exclusively on the business surplus market across a variety of
targeted industries. We have developed in-depth expertise within each of our
targeted industries in order to better serve the complex needs of buyers and
sellers in these industries. Although we intend to continually expand into new
industries, we currently focus on eight specific industry classifications:

<TABLE>
    <S>                                          <C>
    - Apparel / Footwear / Accessories           - Computer Products
    - Food and Beverage                          - Health and Beauty Care
    - Housewares / Household Products            - Automotive
    - Metalworking Machinery                     - Power and Utility Equipment
</TABLE>

                                       1
<PAGE>
Our sales personnel focus on key decision makers in our targeted industries to
create compelling listings of business surplus assets. We also focus resources
on bringing a broad range of buyers to our marketplace and making it easier for
them to find the assets they seek. Finally, our trade facilitation personnel
work to bring transactions to closure, by ensuring proper merchandising of
items, identifying potential buyers and facilitating communication between
parties.

                                  OUR STRATEGY

    Our objective is to be the world's leading business-to-business Internet
marketplace for buyers and sellers of business surplus. To achieve our
objective, we intend to:

    - build a critical mass of buyers and sellers;

    - leverage our first-mover advantage and expand our brand awareness;

    - create alliances with strategic partners that can help bring more buyers
      and sellers to our marketplace, broaden our service offerings and enhance
      the depth and breadth of our targeted industries;

    - offer a broad range of value-added services to our customers;

    - expand the number of our targeted industries and the depth of our industry
      expertise; and

    - integrate our marketplace into our customers' internal information
      systems.

                            OUR STRATEGIC ALLIANCES

    We are entering into strategic alliances with four major types of
organizations to increase the activity in our marketplace. These include:

    - targeted industry anchors such as General Electric Capital Corporation;

    - traditional liquidators and brokers such as Quality King Distributors;

    - traffic drivers such as PurchasePro.com and the National Association of
      Wholesaler-Distributors; and

    - ancillary service providers such as i-Escrow and Emery Worldwide.

                              RECENT DEVELOPMENTS

    In March 2000, we entered into a strategic alliance agreement with General
Electric Capital Corporation under which we expect GE Capital to encourage its
business units and affiliates to post assets on our marketplace, promote these
assets to their customers and provide remarketing services to their customers.
In addition, we sold approximately $15.0 million of Series D preferred stock and
warrants to purchase up to 2,392,500 shares of our common stock to GE Capital
Equity Investments, Inc., an affiliate of GE Capital.

                             CORPORATE INFORMATION

    We were incorporated in Delaware on December 11, 1998. Our principal
executive offices are located at 410 Saw Mill River Road, Suite 2065, Ardsley,

                                  RISK FACTORS

    THIS OFFERING INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD CAREFULLY CONSIDER
THE RISKS DESCRIBED BELOW BEFORE YOU DECIDE TO BUY OUR COMMON STOCK. IF ANY OF
THE FOLLOWING RISKS ACTUALLY OCCUR, OUR BUSINESS, FINANCIAL CONDITION OR RESULTS
OF OPERATIONS WOULD LIKELY SUFFER. IN THIS CASE, THE TRADING PRICE OF OUR COMMON
STOCK COULD DECLINE, AND YOU MAY LOSE ALL OR PART OF YOUR INVESTMENT.

OUR LIMITED OPERATING HISTORY MAKES EVALUATING OUR BUSINESS AND FUTURE PROSPECTS
DIFFICULT.

    We have a very limited operating history. Our company was founded in
December 1998 and did not generate revenues until after we launched our
marketplace in April 1999. Because our operating history is so limited, it is
very difficult to evaluate our business and our future prospects. We will
encounter risks and difficulties frequently encountered by companies in an early
stage of commercial development in new and rapidly evolving markets. In order to
overcome these risks and difficulties, we must, among other things:

    - execute our sales and marketing strategy successfully;

    - increase the number of businesses that use our Internet marketplace to
      transact in business surplus;

    - attract a sufficient number of sellers of business surplus to our Internet
      marketplace to ensure the availability of a wide range of products;

    - attract a sufficient number of buyers to purchase business surplus through
      our Internet marketplace to sustain a competitive market for the products
      available through our site;

    - enter into long-term agreements with strategic partners to bring more
      products and more buyers and sellers to our Internet marketplace, and to
      make available to buyers and sellers related value-added services; and

    - continue to attract, hire, motivate and retain qualified personnel.

If we fail to achieve these objectives, we may not realize sufficient revenues
or net income to succeed.

BECAUSE OUR COMPANY AND OUR BUSINESS CONCEPT ARE NEW AND UNPROVEN, OUR PAST
PERFORMANCE CANNOT HELP TO PREDICT OUR CHANCES FOR SUCCESS.

    We have only been operating our business and generating revenues for a short
period of time, and the entire online business surplus industry has only
recently emerged. Both our company and our way of conducting business are
entirely new. We cannot rely upon our performance over the limited period since
our inception to help us predict our chances for success in the future, nor are
there others in our industry to whom we can look for guidance on how to succeed.

MOST OF OUR REVENUES LAST YEAR CAME FROM A FEW TRANSACTIONS FOR A FEW CLIENTS
AND ARE NOT INDICATIVE OF OUR BUSINESS.

    Substantially all of our revenues last year were derived from a few
transactions in our marketplace, on which we collected sales commissions and
listing fees. If these transactions had not occurred, our revenues would have
been even lower and our net loss even higher in 1999. We do not have contractual
relationships with any of the parties that accounted for these revenues last
year that would compel them to list additional business surplus for sale in our
marketplace, and even if we did, we could not assure you that anything listed
would ultimately be sold and result in revenues for us. Accordingly, we do not
believe that our 1999 revenues are meaningful indicators of our business and
future prospects.

                                       5

BUYERS AND SELLERS OF EXCESS INVENTORY AND IDLE ASSETS MAY NOT ADOPT OUR ONLINE
METHOD OF BUYING AND SELLING BUSINESS SURPLUS.

    Business-to-business online transactions are a new method of buying and
selling business surplus that potential buyers and sellers may not adopt. If
businesses do not adopt our transaction method, then our business may not
succeed. In order to accept our method, sellers and buyers must adopt new
practices that are different from their traditional practices. Traditional
purchasing is often based on long-standing relationships between a seller and a
few buyers. Buyers and sellers of business surplus often negotiate prices
directly, with sellers frequently directing their business to chosen buyers
based on factors such as price and familiarity. Our services may be disruptive
to existing, long-standing relationships because, in order to use our services,
a seller must be willing to leave the comfort and certainty of dealing with one
or a few trusted buyers or intermediaries, and instead take a chance on a more
impersonal marketplace, which may or may not deliver a more favorable price in
the end. Similarly, buyers must be willing to rely less upon personal
relationships with sellers and intermediaries and more upon their own judgment
in selecting products to purchase and making offers of prices to pay. We cannot
assure you that enough businesses will choose to adopt our method or will do so
at sufficient levels to sustain our business.

WE MAY NOT BE ABLE TO ATTRACT ENOUGH BUYERS AND SELLERS TO CREATE A MEANINGFUL
MARKETPLACE.

    Our marketplace works best for buyers when a large selection and quantity of
business surplus items are available in our marketplace, so that there is a
higher probability that a buyer will find what it is looking for, and best for
sellers when many buyers are present in our marketplace, so that true
competition for available products develops and market prices prevail. This
means that we need to bring a great deal of traffic to our site in order for our
online method of buying and selling business surplus to work optimally. To do
so, we may have to incur significant costs and may have to issue equity in
marketing and forming strategic alliances. We may not be able to achieve the
volume of traffic that we desire, induce potential sellers to post their items
or potential buyers to make actual purchases or achieve a desirable balance
among buyers, sellers and products. If our marketplace does not reach critical
mass or if a competitive marketplace eclipses ours, we may be unable to continue
to bring buyers and sellers together. Any of these failures may harm our
business by reducing revenues and increasing costs.

ONCE BUYERS AND SELLERS MEET IN OUR MARKETPLACE, THEY MAY INTENTIONALLY AVOID
OUR MARKETPLACE IN THE FUTURE.

    It is possible that once buyers and sellers have located one another in our
marketplace, they will not use our marketplace to transact with each other in
the future. Sellers may initially use our marketplace to gain contact with a
group of buyers and, in the future, contact these buyers directly. This kind of
seller activity would decrease the number of listings on our marketplace and
impair our financial performance.

SELLERS MAY CREATE CHANNEL CONFLICT FOR THEIR OWN PRODUCTS BY SELLING TO
COMPETING DISTRIBUTORS THROUGH OUR SITE, AND MAY REDUCE THEIR PARTICIPATION IN
OUR MARKETPLACE AS A RESULT.

    A business disposing of excess inventory in our marketplace may experience
channel conflict, which occurs when a company's excess inventory ends up in the
hands of inappropriate distributors, such as discount warehouses, which will
sell the goods to the original company's own customer base at a cheaper price.
Channel conflict could harm existing relationships between sellers and their
distributors, as well as between actual and potential buyers and their resale
customers. Users who experience negative consequences resulting from channel
conflict in sales consummated in our marketplace may end their business
relationships with us. This could harm our reputation and reduce our revenues.

                                       6
<PAGE>
WE MAY NOT BE ABLE TO COLLECT ALL OF THE SALES COMMISSIONS TO WHICH WE ARE
ENTITLED.

    Our business generates the majority of its revenues through sales
commissions paid by the seller when products are sold through our marketplace.
Because we do not take possession of any of the products posted on our site, and
because we do not pack or ship products after they are sold, we may not be aware
of all sales transactions that actually take place in our Internet marketplace.
Thus, we may not be able to collect payment for all sales transactions that are
initiated on TradeOut.com, and our revenues and financial performance may suffer
as a result.

FAILURES OF HARDWARE SYSTEMS OR SOFTWARE COULD UNDERMINE OUR USERS' CONFIDENCE
IN OUR RELIABILITY.

    A significant disruption in our online service could seriously undermine our
users' confidence in our business. The businesses that use our marketplace hold
us to a high standard of reliability and performance. We have experienced
occasional system outages, which we believe will continue to occur from time to
time. These outages have stemmed from a variety of causes, including third-
party hardware and software problems, human error and general maintenance. The
volume of traffic on our Web site has been increasing dramatically, requiring us
to expand and upgrade our technology, software and network infrastructure and to
add new personnel. We may be unable to accurately project the rate or timing of
increases, if any, in the use of the TradeOut.com service or expand and upgrade
our systems and infrastructure to accommodate such increases in a timely manner.
Any failure to expand or upgrade our systems at least as fast as the growth in
demand for capacity could cause our Internet marketplace to become unstable and
possibly cease to operate for periods of time. Unscheduled downtime could harm
our business.

    Some of the elements set forth above are not within our control, such as
Internet connectivity and software, hardware and telecommunications equipment we
purchase from others. Some users of our site may use older or inferior
technologies, which may not operate properly. In addition, hardware and software
are potentially vulnerable to interruption from power failures,
telecommunications outages, network service outages and disruptions, natural
disasters, and vandalism and other misconduct.

WE MAY NOT BE ABLE TO DETERMINE OR DESIGN THE FEATURES AND FUNCTIONALITY THAT
OUR USERS REQUIRE OR PREFER.

    Our success depends upon our ability to accurately determine the features
and functionality that our users require or prefer in using electronic commerce
as a method of buying and selling business surplus. We must be able to
successfully design and implement these functions and features on our site. We
may need to rely upon relationships with third-party partners to provide
additional value-added services that our customers demand and that we cannot
otherwise provide, such as appraisal and financing services. If we are unable to
determine or design the features and functionality that customers require or
prefer, or if we are unable to bring desired third-party services onto our site,
then customers may seek alternative online marketplaces in which to transact
business, or may prefer traditional offline purchase and sale methods. We cannot
be certain that the features and functionality that we currently offer on our
site, or those that we may offer in the future, will satisfy the requirements or
preferences of our current or potential users.

IF WE DO NOT ADEQUATELY MAINTAIN THE INTEGRITY OF INFORMATION IN OUR
MARKETPLACE, USERS MAY SEEK ALTERNATIVE MARKETPLACES AND OUR RESULTS COULD
SUFFER.

    Users of our marketplace rely upon the information that is made available
there. Sellers post descriptions of offered business surplus and depend upon the
descriptions matching those that they provide. Buyers propose prices that they
are willing to pay, or accept posted offer prices, and rely upon those prices
being accurate. If product descriptions are not accurate, or if bid and asked
price information is not correct, buyers and sellers may lose confidence in
their ability to transact

                                       7
<PAGE>
business in our marketplace and may revert to traditional methods of buying and
selling business surplus or may avail themselves of the services offered by our
competitors. Our failure to maintain the integrity of information in our
marketplace could result in a loss of confidence by users and a corresponding
reduction in use of our online marketplace which would reduce our revenues and
materially harm our business.

WE DO NOT VALIDATE THE IDENTITY OR RELIABILITY OF USERS OF OUR INTERNET
MARKETPLACE, AND OUR BUSINESS COULD BE HARMED BY FRAUDULENT ACTIVITIES IN OUR
MARKETPLACE.

    Our future success will depend largely upon sellers reliably delivering and
accurately representing their posted goods and upon buyers paying the agreed
purchase price. Currently, any buyer or seller can register with and use our
Internet marketplace, and we do not validate its identity or reliability. In the
past, some users have not received the purchase price or the goods that were to
be exchanged and we expect this to continue. While we can suspend users who fail
to fulfill their delivery obligations to other users, we do not have the ability
to require users to make payments or deliver goods. Negative publicity generated
as a result of fraudulent or deceptive conduct by users of our service could
damage our reputation and cause users to seek alternatives to our site, which
would reduce our revenues, or lead to costly litigation initiated by users
seeking to recover the benefit of their bargain.

WE DEPEND ON OUR STRATEGIC RELATIONSHIP WITH GE CAPITAL; THE LOSS OF THIS
STRATEGIC PARTNER WOULD SIGNIFICANTLY REDUCE OUR REVENUES AND NET INCOME.

    General Electric Capital Corporation, through its affiliates, runs a
substantial remarketing business for used and surplus assets that reaches a
significant number of remarketing customers. Under our agreement with GE
Capital, we expect it to encourage its business units and affiliates to post
assets on our marketplace, promote these assets to their existing customers and
provide remarketing services to their customers. We would then receive a
commission on the sale of these assets on our site. Our five-year alliance with
GE Capital provides certain financial incentives for GE Capital business units
and affiliates to post their assets on our site, but does not obligate them to
do so. If we fail to provide an appropriate level of customer service to GE
Capital or its business units and affiliates, or if our service does not
significantly enhance its current remarketing efforts, it may elect to post its
assets elsewhere.

    GE Capital and its affiliates may decide not to sell their assets through
our marketplace. The loss or partial loss of this partner or its failure to
increase usage of our marketplace would significantly diminish our revenues and
operating results, forcing us to curtail our growth plans and incur greater
losses. Even if we maintain this relationship, we may not be successful in
growing and diversifying our user base.

FORMING STRATEGIC RELATIONSHIPS WITH LARGE CORPORATE PARTNERS MAY NOT RESULT IN
MEANINGFUL INCREASES IN THE QUANTITY OR QUALITY OF GOODS AVAILABLE IN OUR
MARKETPLACE, AND THUS MAY NOT ATTRACT MORE BUYERS OR SELLERS.

    We are focusing significant attention on securing relationships with large
corporations to post their business surplus for sale in our marketplace. While
these corporations dispose of a substantial amount of business surplus each
year, we cannot assure you that they will post any significant portion of their
surplus assets in our marketplace, or that they will post goods that are readily
saleable. Without a broad range of goods available for purchase, we may not
attract enough buyers to create a meaningful marketplace, and without enough
buyers we may lose our ability to induce sellers to continue to post products or
to add more products for sale. Any of these failures would reduce our revenues
and harm our business.

                                       8
<PAGE>
WE HAVE ONLY RECENTLY ASSEMBLED OUR MANAGEMENT TEAM.

    We have recently expanded our management team dramatically, adding new
executive officers in almost every function. These individuals have generally
not worked with one another before, and we may not be able to forge an effective
working relationship among them. Moreover, all of our new managers are still
learning about our company and our industry. If our senior management cannot
work together effectively and cannot master the details of our business and our
market, then our business will be harmed and we will incur additional costs in
seeking and retaining new management personnel.

THE LOSS OF OUR KEY EXECUTIVES WOULD DISRUPT OUR BUSINESS.

    The loss of any member of our key management team would significantly
disrupt our business. We rely on the leadership and vision of key members of our
senior management team, including:

    - Brin McCagg, our founder and Chairman;

    - George Samenuk, our Chief Executive Officer and President; and

    - James Mooney, our Chief Financial Officer.

    These officers are instrumental to the management and growth of our
business. The loss of any of these executives could disrupt our growth or result
in lost revenues or a decrease in net income. Although we maintain a "key man"
life insurance policy on Mr. McCagg and intend to obtain a policy on
Mr. Samenuk prior to the closing of this offering, the proceeds of those
policies would not be sufficient to compensate us for the loss of these
individuals to our business. In addition, although we have agreements with our
key employees that prohibit them from soliciting any of our customers for a
period of one year following the termination of employment, our key employees
could otherwise compete with us.

WE MAY NOT BE ABLE TO HIRE OR RETAIN QUALIFIED STAFF.

    If we cannot attract and retain enough qualified and skilled staff, the
growth of our business may be limited. Our ability to grow our business depends,
in part, on our ability to attract and retain staff with professional experience
that is relevant for attracting sellers and buyers, facilitating trades,
developing new technology and other functions we perform in connection with our
services and marketplace. Competition for personnel with these skill sets is
intense. Some technical job categories are under conditions of severe shortage
in the United States. In addition, restrictive immigration quotas could prevent
us from recruiting skilled staff from outside the United States. We may not be
able to recruit or retain the caliber of staff required to carry out essential
functions at the pace necessary to sustain or grow our business.

IF WE FAIL TO CONTINUALLY IMPROVE OUR TECHNOLOGY, OUR BUSINESS WILL SUFFER.

    Our services and the business-to-business electronic commerce market are
characterized by rapidly changing technologies and frequent new product and
service introductions. We may fail to introduce new online purchase and sale
technology on a timely basis or at all. If we fail to introduce new technology
or to improve our existing technology in response to industry developments, we
could experience frustration from our users that could lead to a loss of
revenues. Our technology is complex, and accordingly may contain undetected
errors or defects that we may not be able to fix. Reduced market acceptance of
our services due to errors or defects in our technology would harm our business
by reducing our revenues.

THE CAPACITY CONSTRAINTS OF OUR PERSONNEL AND TECHNOLOGY RESOURCES MAY LIMIT OUR
GROWTH.

    If we are unable to undertake new business due to a shortage of staff or
technology resources, our growth will be impeded. At times, our customers ask us
to post large quantities of business

                                       9
<PAGE>
surplus in our marketplace, straining our resources in terms of both people and
technology. At the same time, growth of our business requires that we expand
product and service offerings to drive users to our marketplace. This, too,
often requires a substantial amount of time from our marketing and trade
facilitation staff. If our staff does not have the time to develop our database
of products and services while serving our current users, we may not be able to
grow sufficiently to succeed. Therefore, there may be times when our
opportunities for revenue growth may be limited by the capacity of our internal
resources rather than by the absence of market demand.

FAILURE TO MANAGE OUR GROWTH COULD REDUCE OUR REVENUES OR NET INCOME.

    In order to execute our business plan, we must grow significantly. This
growth will place a significant strain on our infrastructure, management,
internal controls and financial systems. We may not be able to effectively
manage our present growth or any future expansion. To support our growth, many
of our key managerial, technical and sales positions have been recently filled
with new employees who have not had time to be fully integrated into our
business. Inadequate integration and training of our employees may result in
underutilization of our workforce and may reduce our revenues or net income.

OUR QUARTERLY OPERATING RESULTS ARE VOLATILE AND DIFFICULT TO PREDICT; IF WE
FAIL TO MEET THE EXPECTATIONS OF PUBLIC MARKET ANALYSTS OR INVESTORS, THE MARKET
PRICE OF OUR COMMON STOCK MAY DECLINE.

    We have only been in business since December 1998, and our quarterly
operating results have varied widely in the past and will likely vary
significantly in the future. We derive most of our revenues from commissions on
sales completed on our site. These sales vary greatly in dollar amount due to
the type of assets being sold, the sales format used, the listing size and the
nature of the business surplus market. Additionally, we have no control over
when business surplus will be posted on our Web site or the length of the sales
cycle relating to the sale format the seller chooses. As a result, there may be
significant fluctuations in the amount of revenues generated in different
periods. Moreover, charges related to outstanding warrants that we have issued
to strategic alliance partners and that vest upon the attainment of performance
milestones may be very significant in future periods and may more than offset
any income that we have in those periods. We believe that period-to-period
comparisons of our results of operations are not meaningful and you should not
rely upon them as indicators of future performance. Our operating results will
likely fall below the expectations of securities analysts or investors in some
future quarter or quarters. Our failure to meet these expectations may result in
a decrease in the market price of our common stock.

WE USE SIGNIFICANTLY MORE CASH THAN WE GENERATE.

    Since our inception, our operating and investing activities have used more
cash than they have generated. Because we will continue to need substantial
amounts of working capital to fund the growth of our business, we expect to
continue to experience significant negative operating and investing cash flows
for the foreseeable future. We may need to raise additional capital in the
future to meet our cash requirements. We may not be able to find additional
financing, if required, on favorable terms or at all. If we raise additional
funds through the issuance of equity, equity-related or debt securities, these
securities may have rights, preferences or privileges senior to those of the
rights of our common stock, and our stockholders may experience additional
dilution to their equity ownership.

                                       10
<PAGE>
OUR SPENDING ON INCREASED CAPACITY PRECEDES OUR RECEIPT OF REVENUES; THIS COULD
CAUSE OUR GROSS MARGINS TO BE VOLATILE.

    We must hire personnel, acquire equipment, develop our technology and expand
our facilities in anticipation of increasing the volume of transactions in our
marketplace and receiving revenues in future periods. Because many of our
expenses for these activities are components of our cost of revenues, our gross
margins are likely to be volatile.

WE MAY NOT BE ABLE TO ADJUST OUR SPENDING QUICKLY; IF WE CANNOT, THEN OUR NET
INCOME WILL BE REDUCED.

    We plan to increase expenditures for our sales and marketing efforts,
development of new technology and improvement of our operational and financial
systems. We have almost no historical financial data upon which we can base our
planned operating costs and capital expenditures, and the data we do have are
very limited and may not be meaningful. Our planned expense levels are
relatively fixed in the short term and are based on our anticipation of future
revenues. We may not be able to forecast revenues accurately due to our limited
operating history. If we fail to predict revenues accurately in relation to our
planned expense levels, then we may be unable to adjust our costs in a timely
manner in response to lower-than-expected revenues, and our net income will be
negatively affected.

WE ANTICIPATE FUTURE LOSSES.

    We have experienced losses every quarter since our inception. Our chances
for future profitability will depend on whether we can increase revenues while
controlling expenses. We may not achieve profitability in the future, or sustain
any future profitability.

WE MAY ACQUIRE OTHER BUSINESSES OR TECHNOLOGIES; IF WE DO, WE MAY BE UNABLE TO
INTEGRATE THEM WITH OUR BUSINESS, OR WE MAY IMPAIR OUR FINANCIAL PERFORMANCE.

    If appropriate opportunities present themselves, we may acquire businesses,
technologies, services or products that we believe are strategic. We do not
currently have any understandings, commitments or agreements with respect to any
acquisition, nor are we currently pursuing any acquisition. We may not be able
to identify, negotiate or finance any future acquisition successfully. Even if
we do succeed in acquiring a business, technology, service or product, we have
no experience in integrating an acquisition into our business; the process of
integration may produce unforeseen operating difficulties and expenditures and
may absorb significant attention of our management that would otherwise be
available for the ongoing development of our business. If we make future
acquisitions, we may issue shares of stock that dilute other stockholders, incur
debt, assume contingent liabilities or create additional expenses related to
amortizing goodwill and other intangible assets, any of which might harm our
financial results and cause our stock price to decline. Any financing that we
might need for future acquisitions may only be available to us on terms that
restrict our business or that impose on us costs that reduce our net income.

THE MARKET FOR BUSINESS-TO-BUSINESS ELECTRONIC COMMERCE PRODUCTS AND SERVICES IS
INTENSELY COMPETITIVE; IF WE CANNOT COMPETE SUCCESSFULLY, OUR BUSINESS WILL
SUFFER REDUCED REVENUES AND NET INCOME.

    Competition in the markets we serve is intense. We must compete with other
online providers of purchase and sale services for business surplus, some of
which have very narrow product focuses and seek to exploit niche markets, and
also with traditional offline businesses such as auctioneers, dealers and other
intermediaries. Individual buyers or sellers of business surplus may continue to
use or create their own online or offline marketplaces for those products in the
future, either alone or in groups, all of which would be direct competitors of
our marketplace. We expect competition from all sources to intensify in the
future. Several of our competitors, both online and

                                       11
<PAGE>
offline, are well-financed and could commit more resources to sales and
marketing efforts, adopt more aggressive promotional and pricing policies and
devote more resources to technology and site development than can we. Moreover,
traditional providers of business surplus disposal services can rely upon their
long-standing relationships with buyers and sellers and their intimate knowledge
of niche markets in which they operate. In order to respond to competitive
changes in this competitive environment, we may from time to time make pricing,
marketing or other strategic decisions that could have a material adverse affect
on our operating results.

    Barriers to entry are low. Competitors can obtain low cost, commercially
available software that provides the same basic site functionality as
TradeOut.com. We believe that the principal competitive factors in this market
are the volume, selection and quality of assets for sale, attracting a large
population of buyers and sellers, delivering superior customer service, building
brand recognition and return customers, enhancing Web site functionality and
ease of use, providing value-added services, the price range of products
available on our site and the reliability of our systems. We may not be able to
compete effectively on all or any of these factors against current and potential
competitors; if we cannot, then our revenues may be reduced and our costs
increased.

FUTURE GOVERNMENT REGULATION OF THE INTERNET AND ONLINE TRANSACTIONS MAY ADD TO
OUR OPERATING COSTS.

    Like many Internet-based businesses, we operate in an environment of
tremendous uncertainty as to potential government regulation. The Internet has
rapidly emerged as a commerce medium, and governmental agencies have not yet
been able to adapt all existing regulations to the Internet environment. Laws
and regulations may be introduced and court decisions reached that affect the
Internet or other online services, covering issues such as user pricing, user
privacy, freedom of expression, access charges, content and quality of products
and services, advertising, intellectual property rights and information
security. In addition, because we offer our services worldwide and facilitate
sales of goods to customers globally, foreign jurisdictions may claim that we
are required to comply with their laws. Any future regulation may have a
negative impact on our business by restricting our method of operation or
imposing additional costs.

    In order to conduct business over our site, users must provide us with
identifying and demographic information. We use this information to track users'
activities in our marketplace and to provide users with certain marketing and
promotional offers. We also plan to share user information with some of our
strategic partners in accordance with the terms of our privacy policies. The
Federal Trade Commission and state agencies have been investigating various
Internet companies regarding their use of personal information. Future
regulation could limit our ability to collect and use this information, and this
limitation could harm our ability to promote our site or our partners' goods or
services to our users.

    As an Internet company, it is unclear in which jurisdictions we may be
deemed to be conducting business. Our failure to qualify to do business in a
jurisdiction that requires us to do so could subject us to fines or penalties
and could result in our inability to enforce contracts in that jurisdiction.
Numerous jurisdictions have laws and regulations regarding the conduct of
auctions and the liability of auctioneers. We do not believe that these laws and
regulations, which were enacted for consumer protection many years ago, apply to
our services. However, one or more jurisdictions may attempt to impose these
laws and regulations on our operations in the future.

WE MAY BECOME SUBJECT TO CERTAIN SALES AND OTHER TAXES THAT COULD ADVERSELY
AFFECT OUR BUSINESS.

    The imposition of sales, value-added or similar taxes could diminish our
competitiveness and harm our business. We do not collect sales or other similar
taxes for items purchased through our

                                       12
<PAGE>
marketplace. Our users are businesses that typically manage and pay their own
sales and use taxes. However, we may be subject to sales tax collection
obligations in the future.

IF WE ARE NOT ABLE TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY RIGHTS, THEN
OUR COMPETITORS MAY BE ABLE TO DUPLICATE OUR SERVICES.

    We rely in part upon our proprietary technology to conduct sales through our
marketplace. Our failure to adequately protect our intellectual property rights
could harm our business by making it easier for our competitors to duplicate our
services. We cannot assure you that we have adequately protected our technology
and processes or that our proprietary rights will result in commercial
advantages for us. We have applied for registration of certain of our trademarks
and our marketing materials are protected by copyright, but these protections
may not be adequate. Although we have registered our domain name in over 75
foreign countries, there are third parties who own foreign registrations of the
TradeOut.com domain name in some countries. These registrations and future
foreign registrations by third parties of the TradeOut.com domain name in
countries where we have not already registered our domain name, could divert
traffic from our site and require us to choose other domain names that are not
easily recognizable. In addition, although we require each of our employees to
enter into a proprietary information and confidentiality agreement, this
agreement may not satisfactorily safeguard our intellectual property.

    We cannot be certain that third parties will not infringe or misappropriate
our proprietary rights or that third parties will not independently develop
similar proprietary information. Any infringement, misappropriation or
independent development could harm our future financial results. There have been
several instances of third parties copying the design and content of our site,
and we expect these attempts to continue in the future. There is nothing we can
do to prevent copying before it occurs. In addition, effective patent,
trademark, copyright and trade secret protection may not be available in every
country in which we provide services. We may, at times, have to incur
significant legal costs and spend time defending our trademarks, copyrights and,
if issued, any patents. Any defense efforts, whether successful or not, would
divert both time and resources from the operation and growth of our business.

    There is also significant uncertainty regarding the applicability to the
Internet of existing laws regarding matters such as property ownership,
copyrights and other intellectual property rights. Legislatures adopted the vast
majority of these laws prior to the advent of the Internet and, as a result,
these laws do not contemplate or address the unique issues of the Internet and
related technologies. We cannot be sure what laws and regulations may ultimately
affect our business or intellectual property rights.

OTHERS MAY ASSERT THAT OUR TECHNOLOGY INFRINGES THEIR INTELLECTUAL PROPERTY
RIGHTS.

    We do not believe that our technology infringes the proprietary rights of
others and, to date, no third parties have notified us of infringement of their
technology, but we may be subject to infringement claims in the future. Patents
have been issued and are continually being issued covering aspects of online
commerce and electronic auction methods, processes and technologies, and, thus,
aspects of our business, processes or technologies may infringe patents held by
third parties now or in the future. The defense of any claims of infringement
made against us by third parties could involve significant legal costs and
require our management to divert time from our business operations. Either of
these consequences of an infringement claim could have a material adverse effect
on our operating results. If we are unsuccessful in defending any claims of
infringement, we may be forced to obtain licenses or to pay royalties to
continue to use our technology. We may not be able to obtain any licenses that
are necessary for us to avoid infringement on commercially reasonable terms or
at all. If we fail to obtain necessary licenses or other rights, or if these
licenses are too costly, we may be prohibited from using certain processes or
technology or conducting certain aspects of our business, and our operating
results may suffer

                                       13
<PAGE>
either from reductions in revenues through our inability to serve users or from
increases in costs to license third-party technology.

OTHERS MAY REFUSE TO LICENSE IMPORTANT TECHNOLOGY TO US OR MAY INCREASE THE FEES
THEY CHARGE US FOR THIS TECHNOLOGY.

    We rely on third parties to provide us with some software and hardware, for
which we pay fees. This software has been readily available, but these third
parties may increase their fees significantly or refuse to license their
software or provide their hardware to us. While other vendors may provide the
same or similar technology, we cannot be certain that we can obtain the required
technology on favorable terms, if at all. If we are unable to obtain required
technology at a reasonable cost, our growth prospects and operating results may
be harmed through impairment of our ability to conduct business or through
increased cost.

SECURITY RISKS AND CONCERNS MAY DETER THE USE OF THE INTERNET FOR CONDUCTING
COMMERCE.

    Concern about the security of the transmission of confidential information
over public networks is a significant barrier to electronic commerce and
communication. Advances in computer capabilities, new discoveries in the field
of cryptography or other events or developments could result in compromises or
breaches of Internet security systems that protect proprietary information. If
any well-publicized compromises of security were to occur, they could
substantially reduce the use of the Internet for commerce and communications.
Anyone who circumvents our security measures could misappropriate proprietary
information, corrupt our listing or pricing data or cause interruptions in our
services or operations. The Internet is a public network, and data are sent over
this network from many sources. In the past, computer viruses have been
distributed and have rapidly spread over the Internet. Computer viruses could be
introduced into our systems or those of our customers, which could disrupt our
technology or make our online services inaccessible to our users. We may be
required to expend significant capital and other resources to protect against
the threat of, or to alleviate problems caused by, security breaches and the
introduction of computer viruses. Our security measures may be inadequate to
prevent security breaches or combat the introduction of computer viruses, either
of which may result in loss of data, increased operating costs, litigation and
possible liability.

OUR INTERNATIONAL OPERATIONS SUBJECT US TO RISKS AND UNCERTAINTIES.

    We face risks in doing business internationally. We provide our services to
international sellers and buyers. We currently serve many users based in Latin
America. We plan to establish subsidiaries there and in other parts of the
world. We expect to incur significant costs for our international operations as
we add staff and facilities to serve foreign markets. These costs, together with
the costs of the overhead needed to comply with legal, regulatory and accounting
requirements that differ from those in the United States, may reduce our net
income.

    In addition, because our services are accessible worldwide, transactions may
occur in our marketplace between parties in restricted jurisdictions. The United
States government prohibits commercial transactions with buyers and sellers in
certain countries. Currently, we do not monitor sales on our site to prevent
transactions with these "denied parties." Our failure to comply with government
restrictions on transactions with parties in these jurisdictions could subject
us to penalties, such as fines or bans on our ability to offer our services.

    Finally, our international operations are subject to disruption from
political and economic instability in the countries in which they may be
located, which may interrupt our ability to conduct business and impose
additional costs upon us.

OUR MANAGEMENT HAS BROAD DISCRETION OVER HOW TO USE THE PROCEEDS OF THIS
OFFERING; WE MAY NOT USE THE PROCEEDS IN WAYS THAT HELP OUR BUSINESS SUCCEED.

    We estimate that our net proceeds from this offering will be $      million,
at an initial public offering price of $      per share and after deducting the
underwriting discount and our estimated offering expenses. Our primary purposes
in making this offering are to increase our working capital, create a public
market for our common stock, facilitate our future access to the public capital
markets and increase our visibility in the marketplace. We have no specific
plans for the net proceeds of this offering other than working capital and
general corporate purposes. Accordingly, our management will have broad
discretion as to how to apply the net proceeds of this offering. If we fail to
use these proceeds effectively, our business may not grow and our revenues and
net income may decline.

OTHER COMPANIES MAY HAVE DIFFICULTY ACQUIRING US, EVEN IF DOING SO WOULD BENEFIT
OUR STOCKHOLDERS, DUE TO PROVISIONS OF OUR CORPORATE CHARTER AND BYLAWS AND
DELAWARE LAW.

    Provisions in our Certificate of Incorporation and Bylaws to be in effect
upon closing of this offering and provisions of Delaware law could make it more
difficult for other companies to acquire us, even if doing so would benefit our
stockholders. Our Certificate of Incorporation and Bylaws will contain the
following provisions, among others, which may inhibit an acquisition of our
company by a third party:

    - a staggered board of directors, where stockholders elect only a minority
      of the board each year;

    - advance notification procedures for matters to be brought before
      stockholder meetings;

    - a limitation on who may call stockholder meetings; and

    - a prohibition on stockholder action by written consent.

We are also subject to provisions of Delaware law that prohibit us from engaging
in any business combination with any "interested stockholder", meaning generally
a stockholder who beneficially owns more than 15% of our stock, for a period of
three years from the date this person became an interested stockholder, unless
various conditions are met, such as approval of the transaction by our Board.
This could have the effect of delaying or preventing a change in control.

OUR STOCK PRICE MAY BE VOLATILE, WHICH COULD RESULT IN SUBSTANTIAL LOSSES FOR
STOCKHOLDERS.

    Before this offering, there has never been a public market for our common
stock. The market price for our common stock is likely to be highly volatile and
subject to wide fluctuations in response to the risks described above and many
other factors, some of which are beyond our control. The market prices for
stocks of Internet companies and other companies whose businesses are heavily
dependent on the Internet have generally proven to be highly volatile, and
particularly so in recent periods.

SUBSTANTIAL SALES OF OUR COMMON STOCK AFTER THE OFFERING COULD CAUSE OUR STOCK
PRICE TO FALL.

    Most of our outstanding shares are currently restricted from resale, but
some may be sold into the market in the near future. Sales of these shares into
the market could cause the market price of our common stock to drop
significantly, even if our business is doing well.

    Immediately following this offering, we will have outstanding      shares of
common stock. This includes the      shares we are selling in this offering.
Assuming that we sell all shares reserved under our directed share program to
the entities or persons for whom these shares have been reserved, we expect that
investors may resell      shares in the public market immediately.

The remaining      %, or      shares, of our total outstanding shares will
become available for resale in the public market as shown in the chart below:

                         180 days after the date of this prospectus due to an
                         agreement many of our stockholders have with the
                         underwriters. However, the underwriters can waive this
                         restriction and allow these stockholders to sell their
                         shares at any time.
</TABLE>

As restrictions on resale end, the market price of our stock could drop
significantly if the holders of these restricted shares sell them or the market
perceives that they intend to sell them.

YOU WILL SUFFER IMMEDIATE AND SUBSTANTIAL DILUTION IN THE BOOK VALUE OF YOUR
INVESTMENT.

    The initial public offering price per share will significantly exceed our
net tangible book value per share. If we were to liquidate immediately after the
offering, investors purchasing shares in this offering would receive a per share
amount of tangible assets net of liabilities that would be less than the initial
public offering price per share. Investors purchasing shares in this offering
will suffer dilution of $      per share from their investment.

                           FORWARD-LOOKING STATEMENTS

    Many statements made in this prospectus under the captions "Prospectus
Summary", "Risk Factors", "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business" and elsewhere are
forward-looking statements that are not based on historical facts. Because these
forward looking-statements involve risks and uncertainties, there are important
factors that could cause actual results to differ materially from those
expressed or implied by these forward-looking statements, including those
discussed under "Risk Factors".

    The forward-looking statements made in this prospectus relate only to events
as of the date on which the statements are made. We undertake no obligation to
update any forward-looking statement to reflect events or circumstances after
the date on which the statement is made or to reflect the occurrence of
unanticipated events.

<PAGE>
                                USE OF PROCEEDS

    We estimate that the net proceeds we will receive from the sale of the
shares of common stock in this offering will be $     million, assuming an
initial public offering price of $     per share and after deducting the
estimated underwriting discount and offering expenses. If the underwriters'
over-allotment option is exercised in full, we estimate that the net proceeds
will be $     million.

    The principal purposes of this offering are to increase our working capital,
to create a public market for our common stock, to facilitate future access to
the public capital market and to increase our visibility in the marketplace. We
expect to use the net proceeds of this offering to expand operations and for
working capital and general corporate purposes. As of the date of this
prospectus, however, we have not made any specific expenditure plans with
respect to the proceeds of this offering. Therefore, we cannot specify with
certainty the particular uses for the net proceeds to be received upon
completion of this offering. Accordingly, our management will have significant
flexibility in applying the net proceeds of the offering. We may, for example,
use a portion of the proceeds for strategic investments or acquisitions;
however, we currently have no commitments or agreements and are not negotiating
any of these transactions.

    Pending any use, the net proceeds of this offering will be invested in
short-term interest-bearing securities.

                                DIVIDEND POLICY

    We have never declared or paid cash dividends on our capital stock. We do
not anticipate paying any cash dividends in the foreseeable future. We currently
intend to retain any future earnings to finance the expansion of our business.
In addition, future bank credit facilities may restrict our ability to pay cash
dividends.

       (4) a one-for-two reverse split of our common stock immediately prior to
           completion of this offering.

                                    DILUTION

    Our pro forma net tangible book value as of December 31, 1999 was
approximately $         million, or $         per share of common stock. Pro
forma net tangible book value per share is determined by dividing the amount of
our total tangible assets less total liabilities by the pro forma number of
shares of common stock outstanding at that date, assuming the sale and issuance
of 5,577,825 shares of our Series D preferred stock and 2,455,588 shares of our
Series E preferred stock and the conversion of all outstanding shares of our
preferred stock. Dilution in net tangible book value per share represents the
difference between the amount per share paid by purchasers of shares of common
stock in this offering and the net tangible book value per share of common stock
immediately after the completion of this offering.

    After giving effect to the issuance and sale of the shares of common stock
offered by us and after deducting the estimated underwriting discount and
offering expenses payable by us, our pro forma net tangible book value as of
December 31, 1999 would have been $         , or $         per share. This
represents an immediate increase in pro forma net tangible book value of $
      per share to existing stockholders and an immediate dilution of
$         per share to new investors purchasing shares in this offering. If the
initial public offering price is higher or lower, the dilution to the new
investors will be greater or less, respectively. The following table illustrates
this per share dilution.

      and 2,455,588 shares of our Series E preferred stock in March 2000; and

    - no exercise of any outstanding stock options or warrants.

    This table excludes options outstanding as of December 31, 1999 to purchase

warrants outstanding as of December 31, 1999 to purchase our common stock at a
weighted average exercise price of $8.59 per share. To the extent that any
outstanding options or warrants are exercised, there will be further dilution to
new investors.

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

    THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH "SELECTED
FINANCIAL DATA" AND OUR FINANCIAL STATEMENTS AND THE NOTES TO THOSE STATEMENTS
APPEARING ELSEWHERE IN THIS PROSPECTUS.

OVERVIEW

    TradeOut.com is a leading business-to-business Internet marketplace for
buyers and sellers of business surplus. We provide an Internet-based solution
that enables businesses to efficiently buy and sell excess inventory and idle
assets globally, 24 hours a day, seven days a week. We were incorporated in
December 1998 and launched our marketplace in April 1999.

    Substantially all of our revenues to date have been derived from listing
fees and sales commissions paid by sellers. We do not charge fees to buyers and,
to date, we have not sold advertising on our site. Sellers typically pay a
nominal listing fee per item and, if the item is sold, a sales commission based
on the purchase price. We intend to pursue future opportunities to derive
revenues from ancillary valued-added services that will assist buyers and
sellers to take better advantage of our marketplace, including logistics
support, financing and credit, escrow accounts, inspections, appraisals,
insurance and shipping. We may provide these services ourselves or through
third-party providers.

    Revenues from listing fees are recognized over the period that the item is
posted on our Web site. Revenues related to sales commissions are recognized at
the time the item is sold or the sale or auction for the item is successfully
concluded, which occurs when a buyer has met a seller's asking price and the
sale duration has expired. We have established an allowance for sales returns
based on our historical experience and for failures by buyers and sellers to
consummate a transaction. We do not take possession of either the item being
sold or the buyer's payment for the item. Fees to sellers are aggregated and
billed twice a month. We have no procurement, carrying or shipping costs and no
inventory risk.

    We have entered into several strategic business alliance agreements pursuant
to which we pay a sales commission to our strategic alliance partners based on a
percentage of the commission revenues or gross sales dollars arising from the
successful sale of merchandise they post or refer to our Internet marketplace.
In addition to receiving sales commissions, certain strategic alliance partners
have been issued warrants to purchase shares of our common stock for $2.00 per
share. The vesting of these warrants is conditioned upon the attainment of
certain target sales levels over the terms of the strategic alliance agreements.
The maximum number of such warrants issued under agreements in place as of
March 14, 2000 is 3,409,934. Our strategic alliance agreements stipulate that
these warrants are earned and granted over a period of one to five years. We
will recognize a "stock-based strategic alliance cost" for the estimated fair
market value of the warrants in each quarter in which the sales target is
achieved and the warrants are earned. The charge will be based on the fair
market value of the underlying shares at the time the quarterly sales target is
achieved or achievement is probable. Such charges could be significant. We
intend to enter into similar strategic arrangements with other business surplus
sellers.

    We recorded cumulative deferred compensation of approximately $868,000
through December 31, 1999, which represents the difference between the exercise
price of some stock options granted in 1999, and the fair market value of the
underlying common stock at the date of grant. The difference is recorded as a
reduction of stockholders' equity and amortized over the vesting period of the
applicable options, typically over three to five years. Of the total deferred
compensation amount, approximately $91,000 was amortized during the year ended
December 31, 1999. The amortization of deferred compensation is generally
recorded as an operating expense.

                                       22
<PAGE>
As a result, we currently expect to record the following amounts as deferred
compensation expense annually with respect to options outstanding at
December 31, 1999:

    - 2000--$280,000;

    - 2001--$280,000;

    - 2002--$195,000;

    - 2003--$11,000; and

    - 2004--$11,000.

    We have incurred significant net losses and negative cash flows from
operations since our inception. At December 31, 1999, we had an accumulated
deficit of $19.0 million. These losses have been funded primarily through the
issuance of our equity securities. We intend to continue to invest heavily in
marketing and brand development to bring more buyers and sellers to our
marketplace. As a result, we believe that we will continue to incur net losses
and negative cash flows from operations for the foreseeable future. Moreover,
the rate at which these losses will be incurred is likely to increase
significantly from current levels.

    We have a very limited operating history. Our company was founded in
December 1998 and did not generate revenues until after we launched our Internet
marketplace in April 1999. Because our operating history is so limited, you
cannot evaluate our business and our future prospects based on our historical
results.

    Our quarterly operating results have varied in the past and will likely vary
significantly in the future. We derive our revenues primarily from commissions
on sales completed in our Internet marketplace. These sales vary greatly in
dollar amount depending on the type of assets being sold, the sales format used,
the listing size and the nature of the business surplus market generally. As a
result, there may be significant fluctuations in the amount of revenues
generated in different periods. Moreover, charges related to outstanding
warrants that we have issued to strategic alliance partners and that vest upon
the attainment of performance milestones may be very significant in future
periods and may more than offset any income that we have in those periods. We
believe that period-to-period comparisons of our results of operations are not
meaningful and you should not rely upon them as indicators of future
performance.

RESULTS OF OPERATIONS

    REVENUES

    Total revenues for the year ended December 31, 1999 were $828,000. We did
not recognize any revenues in 1998. In 1999, revenues consisted of sales
commissions and, to a lesser extent, listing fees.

    COST OF REVENUES

    Cost of revenues primarily consists of compensation for customer service and
Web site operations personnel, Internet service provider connectivity charges
and sales commissions paid to strategic partners. Cost of revenues was $529,000
in 1999 and gross profit was $299,000 during the same period. We anticipate that
our cost of revenues will increase significantly in future periods as we expand
our Web site operations group and our Web site facilities and that our gross
profit margin will vary widely, as some of these costs do not bear any direct
proportional relationship to revenues in the periods when the costs are
incurred.

                                       23
<PAGE>
    SALES AND MARKETING

    Sales and marketing expenses primarily consist of compensation for sales and
marketing personnel, advertising, trade show and other promotional costs and
overhead costs. Sales and marketing expenses were $14.1 million in 1999. We did
not incur any sales and marketing expenses in 1998. We expect sales and
marketing expenses to continue to increase in absolute dollars for the
foreseeable future as we:

    - continue our branding campaign;

    - expand our direct sales force and trade facilitation staff;

    - increase the number of trade shows we participate in; and

    - grow our database marketing infrastructure and personnel.

    RESEARCH AND DEVELOPMENT

    Research and development expenses consist primarily of compensation for our
research and development staff, payments to outside contractors and, to a lesser
extent, depreciation in equipment used for research and development and
associated overhead costs. We expense research and development costs as they are
incurred. Research and development costs increased from $8,000 in 1998 to
$2.2 million in 1999. The increase was due to costs associated with the increase
in research and development needed to support the initial and ongoing
development of our marketplace.

    GENERAL AND ADMINISTRATIVE

    General and administrative expenses consist primarily of compensation for
personnel and, to a lesser extent, fees for outside professional advisers and
other overhead costs, including occupancy expense. General and administrative
costs were $3.0 million in 1999 compared to $42,000 in 1998.

    INTEREST AND OTHER INCOME, NET

    Interest and other income, net, consists of interest earned on cash, cash
equivalents and short-term investments offset by interest expense. Interest and
other income, net, was $380,000 in 1999 and $0 in 1998. The increase was
primarily due to interest earned on the proceeds from the sale of our preferred
stock.

    STOCK-BASED COMPENSATION

    In connection with the grant of certain stock options through December 31,
1999, we have recorded aggregate unearned compensation of $868,000, which amount
is being amortized over the vesting period of the options, typically three to
five years. Of the total unearned compensation, approximately $91,000 was
amortized in 1999 and $0 was amortized in 1998. See note 5 of the notes to our
financial statements.

LIQUIDITY AND CAPITAL RESOURCES

    Since inception, we have financed our operations primarily through private
placements of our preferred stock. As of December 31, 1999, we had cash and cash
equivalents of $19.0 million. Subsequent to December 31, 1999, we raised
approximately $15.0 million from the sale of 5,577,825 shares of our Series D
preferred stock and approximately $25.0 million from the sale of 2,455,588
shares of our Series E preferred stock.

                                       24
<PAGE>
    Cash used in operating activities was $25,000 in 1998 and $15.8 million in
1999. Cash used in operating activities was primarily attributable to costs
associated with the development of our Internet marketplace, the expansion of
our sales force and the expansion of our administrative and operations staff to
support our growth.

    Cash used in investing activities was $0 in 1998 and $1.9 million in 1999.
Cash used in investing activities has primarily been comprised of software
development and purchases of office equipment and furniture.

    Cash provided by financing activities was $100,000 in 1998 and
$36.7 million in 1999. In 1998, we raised $100,000 from the sale of our common
stock. In 1999, we raised an aggregate of $1.3 million from the sale of our
common stock in January and February and $35.4 million from the sale of our
preferred stock in April, August and October.

    If revenues attributable to GE Capital and its affiliates under our
strategic alliance agreement with GE Capital do not exceed specified target
levels for the one-year period beginning July 1, 2000, or a later date if the
parties agree, then we are obligated to repurchase up to 929,613 shares of
common stock held by GE Capital Equity Investments at a price equal to 125% of
the amount GE Capital Equity Investments paid for those shares.

    We believe that our existing capital resources, together with the proceeds
from the sale of our common stock in this offering, will be sufficient to
satisfy our cash requirements for the next 12 months. To the extent these
resources are insufficient to satisfy our cash requirements for that period, we
will be required to raise additional funds through equity or debt financings. We
may not be able to raise these funds on favorable terms or at all.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Investments
and Hedging Activities" (SFAS No. 133). SFAS No. 133 establishes a new model for
accounting for derivatives and hedging activities and supersedes a number of
existing standards. SFAS No. 133 is effective for all fiscal quarters of fiscal
years beginning after June 15, 2000. We do not expect the adoption of SFAS
No. 133 to have a material impact on our financial position or results of
operations.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    Most of our cash equivalents, short-term investments and capital lease
obligations are at fixed interest rates. The fair value of these investments is
affected by changes in market interest rates. However, because our investment
portfolio is primarily comprised of investments in high grade commercial paper,
an immediate 10% change in market interest rates would not have a material
effect on the fair market value of our portfolio. Therefore, we would not expect
our operating results or cash flows to be affected to any significant degree by
the effect of a sudden change in market interest rates on our investment
portfolio.

QUARTERLY RESULTS OF OPERATIONS

    The following tables present our operating results for the period from
December 11, 1998 (date of inception) to December 31, 1998, and for each of the
four fiscal quarters in the year ended December 31, 1999. The information for
each of these periods is unaudited. In the opinion of management, all necessary
adjustments, which consist only of normal and recurring accruals, have been
included to fairly present the unaudited quarterly results. These data should be
read together with our financial statements and the notes to those statements
included elsewhere in this prospectus.

OVERVIEW

    TradeOut.com is a leading business-to-business Internet marketplace for
buyers and sellers of business surplus. We provide an Internet-based solution
that enables businesses to buy and sell excess inventory and idle assets
globally, 24 hours a day, seven days a week. Our solution benefits both buyers
and sellers by centralizing the fragmented business surplus market and
streamlining the traditionally cumbersome paper- and fax-based sales and
procurement process. As a result, sellers can reach a broader global base of
potential buyers and buyers can access a wider range of business surplus across
a variety of industries. Moreover, our solution enables both buyers and sellers
to significantly shorten their sales and procurement cycles, reduce transaction
costs and take advantage of the efficiencies resulting from the use of our
marketplace.

    Through December 31, 1999, business users from 43 different countries had
posted more than 8,400 items for sale on our site. At December 31, 1999,
approximately $979 million of business surplus was posted for sale on
TradeOut.com. As of December 31, 1999, more than $15.0 million worth of excess
inventory and idle assets had been sold through our marketplace. At
December 31, 1999, we had approximately 12,700 registered users, and we are
currently registering approximately 100 new users per day. In 1999, we
recognized approximately $828,000 in revenues.

INDUSTRY BACKGROUND

    GROWTH OF BUSINESS-TO-BUSINESS ELECTRONIC COMMERCE

    Businesses are increasingly relying on the Internet to access and share
information, as well as to purchase and sell products and services. Because
businesses have recognized the power of the Internet to improve efficiency,
streamline existing complex processes, lower costs, find new buyers and create
new markets, Internet-based business-to-business commerce is poised for rapid
growth. Forrester Research estimates that business-to-business electronic
commerce will grow from $406.2 billion in 2000 to $2.7 trillion in 2004.

    The Internet enables the creation of centralized marketplaces that allow
widely dispersed buyers and sellers to interact and facilitates the efficient
exchange of product and pricing information. Many businesses have capitalized on
this unique attribute of the Internet to create centralized consumer trading
marketplaces for a variety of consumer goods. The growing popularity of these
consumer-oriented Web sites and the opportunity presented by
business-to-business electronic commerce have spurred the creation of
business-to-business Internet marketplaces. The centralized structure and
potential for increased efficiency and cost savings create a more appealing way
for businesses to buy and sell goods.

    THE BUSINESS SURPLUS MARKET

    Most companies generate excess inventory and idle assets, known as business
surplus. Businesses create excess inventory in the ordinary course of business
as a result of manufacturer overruns, the discontinuation of products, customer
returns, retail overstocks, the introduction of new lines of merchandise and
evolving market preferences. Businesses also have idle capital assets resulting
from equipment upgrades, facility relocations, office equipment replacement and
the expiration of leases. Business surplus can adversely affect an
organization's financial performance by tying up capital that could otherwise be
invested more productively. In addition, businesses incur costs associated with
storing, tracking and maintaining business surplus. We estimate that the market
for business surplus totaled more than $400 billion worldwide in 1999.

                                       27

    INEFFICIENCIES IN THE MARKET FOR BUSINESS SURPLUS

    The traditional methods of selling business surplus are difficult, time
consuming and expensive for the following reasons:

    - FRAGMENTED MARKETPLACE. There are limited comprehensive sources of
      information about the availability of business surplus, and buyers and
      sellers are widely dispersed. Sellers may have difficulty locating buyers
      interested in their products or have limited access to industry
      intermediaries, such as liquidators and brokers. Similarly, buyers may not
      have established relationships with these intermediaries and, therefore,
      may not have sources for goods they need.

    - CUMBERSOME NEGOTIATION PROCESS. It is time consuming for sellers to
      negotiate with multiple potential buyers and for buyers to negotiate with
      multiple sellers by phone or in meetings.

    - LIMITATIONS OF LIVE AUCTIONS. It is expensive for sellers to hold live
      auctions. Moreover, live auctions are limited to buyers who can
      participate at the time and place the auction is held.

    - DIFFICULTIES IN OBTAINING OPTIMAL PRICE. Companies that do not specialize
      in buying and selling business surplus are not always in a position to
      know the market value of particular assets. As a result, a business may
      dispose of its excess inventory by selling to a liquidator or broker at a
      significant discount from the inventory's market value. Because buyers
      also lack established sources of price and market information, they may
      pay higher prices than the desired assets are worth.

As a result of these inefficiencies in the traditional market for business
surplus, many businesses are deterred from undertaking the selling process, and
consequently, from recovering value for these assets and optimizing their
financial performances.

    OPPORTUNITY FOR A BUSINESS-TO-BUSINESS ELECTRONIC COMMERCE SOLUTION

    The inefficiencies, fragmentation and complexities of the traditional means
of buying and selling business surplus have created an opportunity for a more
efficient business-to-business Internet marketplace. The Internet enables buyers
and sellers of business surplus around the world to interact with each other
24 hours a day, seven days a week. Sellers can quickly and easily disseminate
information about their business surplus over the Internet directly to
prospective buyers. Relevant industry, product and pricing information can be
centralized, updated, organized and easily searched. Internet marketplaces
provide a competitive environment for establishing optimal pricing for sellers
and streamline the buying process to reduce transaction costs associated with
traditional purchasing methods. Buyers can also use the Internet to more
efficiently arrange for financing, appraisal, insurance and delivery at the time
of purchase.

THE TRADEOUT.COM SOLUTION

    TradeOut.com is a global business-to-business Internet marketplace that
brings together buyers and sellers of business surplus. Sellers from around the
world can post their business surplus on TradeOut.com in order to convert these
non-performing assets into cash and improve their financial performance by
strengthening their balance sheets and lowering their operating expenses. Buyers
can search, bid for and purchase business surplus more efficiently across a
number of industries throughout the world. We focus exclusively on the business
surplus market across a variety of targeted industries. We have developed
in-depth expertise within each of the industries we have targeted in order to
better serve the complex needs of buyers and sellers in these industries.

                                       28

    Our solution is designed to provide the following key benefits:

    BENEFITS TO SELLERS

    ACCESS TO BUYERS WORLDWIDE.  We enable sellers to offer their excess
inventory and idle assets to buyers throughout the world. Because sellers have
access to a broader global base of potential buyers and can post their listings
according to specific industry categories, they have an increased likelihood of
finding the right buyers for their assets. Moreover, selected buyers can be
targeted via e-mail to drive key buying prospects to sellers' listings. In
addition, utilizing our large database of buyers, our trade facilitation
personnel can identify relevant buyers and actively assist both sellers and
buyers in successfully completing transactions.

    SHORTER SALES CYCLES AND REDUCED COSTS.  Our marketplace streamlines the
traditionally inefficient and cumbersome paper- and fax-based sales process.
Sellers can post and easily update product information which can then be
accessed by potential buyers without the need to contact each one individually.
This reduces labor and communications costs and enables sellers to focus on
their core business rather than devoting time to contacting and negotiating with
multiple buyers on a one-to-one basis. In addition, by utilizing TradeOut.com,
some sellers can choose to outsource certain aspects of their excess inventory
and idle asset disposal effort.

    MORE EFFICIENT PRICING.  TradeOut.com enables sellers to obtain more
efficient pricing than they could through the traditionally fragmented market of
potential buyers and cumbersome individual selling efforts. The greater number
of buyers accessible to sellers on TradeOut.com enables sellers to more
accurately gauge market demand and to determine the optimal asking price.
Moreover, our auction formats allow for concurrent, real-time bidding by
multiple buyers, which creates a more competitive marketplace and increases the
likelihood of obtaining a higher price.

    GREATER FLEXIBILITY AND CONTROL OVER THE SALES PROCESS.  Our marketplace
allows sellers to select the sales process to suit their particular needs. We
offer multiple sale formats, including: standard auctions; first come, first
served sales; and highest sealed bid sales. The ability to select from various
sale formats enables sellers to achieve objectives such as optimizing the sales
price and completing sales more quickly. Sellers that are sensitive to creating
conflict among their distribution channels can conduct private sales by limiting
participation to designated buyers. In addition, sellers can set delivery and
payment terms, and identify product specifications and lot size. We also provide
sellers with real-time reporting features that enable them to review prior
listings and sales history, as well as track the status of their current
listings at any time.

    BENEFITS TO BUYERS

    ACCESS TO WORLDWIDE SELECTION OF BUSINESS SURPLUS.  We provide buyers with a
centralized Internet marketplace where they can locate and acquire a wide range
of business surplus products across a variety of industries from multiple
sellers around the world. Our marketplace allows buyers to conduct tailored
searches for specific products and to post descriptions of items they are
seeking to purchase within our targeted industry categories. In addition, to
further facilitate the buying process, we provide e-mail notification or direct
calls from our trade facilitation personnel to relevant potential buyers when
new products in which they may be interested are posted on our marketplace.

    SHORTER PROCUREMENT CYCLES AND REDUCED COSTS.  We enable buyers to bypass
the traditionally labor-intensive and expensive procurement process. We reduce
the time and related costs for buyers to locate and interact with sellers of
business surplus. Buyers using our marketplace do not have to call or find
potential sellers by telephone, fax or other traditional

                                       29
<PAGE>
marketing methods. They can access up-to-date information easily and quickly
from our centralized Internet marketplace. In addition, buyers can avoid
extensive one-on-one negotiations with multiple sellers regarding price or other
terms. As a result, buyers can significantly shorten their asset procurement
cycles and reduce associated costs.

    BETTER MARKET INFORMATION.  By establishing a critical mass of both sellers
and business assets, we provide buyers with an in-depth view of the market
across a variety of industries for desired assets. In addition, buyers can
compare similar products being offered by different sellers. We also provide
buyers with valuable information to support their purchasing decisions, such as
product condition, specifications, packaging and lot size information. We offer
users access to relevant market news through links to online trade publications
for 24 different industries. This further centralizes the relevant information
business surplus buyers need to make informed purchasing decisions. As a result,
by utilizing our marketplace, buyers can avoid paying unnecessary premiums,
commissions and mark-ups and can more readily obtain desired assets.

OUR STRATEGY

    Our objective is to be the leading global marketplace for buyers and sellers
of business surplus. Key strategies to achieve this objective include:

    ATTRACT A CRITICAL MASS OF BUYERS AND SELLERS TO OUR INTERNET
MARKETPLACE.  Our success is dependent on building a critical mass of sellers
that post a wide range of business surplus on our marketplace and attracting a
large group of potential buyers to make offers on these listings. By adding
sellers and broadening the depth and range of business surplus available on our
marketplace, we create additional value for buyers. By driving more buyers to
our marketplace, we create additional liquidity and value for sellers. We
believe buyers will be drawn to the marketplace with the highest quality and
largest selection of business surplus and sellers will naturally want to
participate in the marketplace with the most buyers. By quickly attracting a
critical mass of both buyers and sellers to our marketplace we intend to create
a network effect, where the value to each participant in the marketplace is
increased with the addition of each new participant. Moreover, we believe that
obtaining this critical mass will create a significant barrier to entry for our
competitors.

    LEVERAGE FIRST-MOVER ADVANTAGE AND EXPAND BRAND AWARENESS.  We believe that
our position as a leading Internet marketplace for excess inventory and idle
assets provides us with a significant competitive advantage. We intend to
leverage our first-mover advantage by expanding market awareness of TradeOut.com
as the premier Internet marketplace for business surplus. We plan to
aggressively promote the TradeOut.com brand through advertising in key business
and trade periodicals, direct mailings to members of trade organizations,
participating in industry events and trade shows, and conducting targeted
promotions and public relations campaigns.

    ESTABLISH ADDITIONAL STRATEGIC ALLIANCES.  We intend to continue to enter
into strategic alliances to increase the number of buyers and sellers that
utilize our marketplace, enhance the depth and breadth of the industries we
serve and broaden the scope of our service offerings. We are seeking to develop
strategic arrangements with companies that sell significant amounts of business
surplus each year and that can consequently provide us with quality listings and
relevant buyers. We recently entered into a strategic alliance with GE Capital,
under which we expect GE Capital to encourage its business units and affiliates
to post assets on our marketplace, promote these assets to their customers and
provide remarketing services to their customers. We are also seeking to create
and broaden our alliances with traditional liquidators, trade associations,
financial institutions and leading electronic commerce companies that can help
drive users to our marketplace.

                                       30
<PAGE>
    OFFER A WIDE RANGE OF SERVICES.  We intend to actively facilitate the sale
of business surplus on our marketplace by offering a variety of pre- and
post-sale services that address the needs of the business surplus market, from
planning to post-sale management. We also intend to provide buyers and sellers
with value-added ancillary services such as logistics support, financing and
credit, escrow accounts, inspections, appraisals, insurance and shipping. We may
provide some of these services ourselves or enter into agreements with
third-party providers of these services. In addition, we intend to develop the
capability to provide customers with an end-to-end outsourced solution that will
enable them to focus on their core business and to more efficiently buy or sell
such assets.

    EXPAND THE BREADTH AND DEPTH OF OUR TARGETED INDUSTRIES.  We believe that
our focus on a number of targeted industries has been a critical component of
our success to date. We intend to establish a presence in additional industries.
In addition, we intend to actively recruit and hire personnel to increase our
expertise within our targeted industries. We believe that expanding our number
of targeted industries and enhancing our industry expertise will provide us with
a competitive advantage and will enable us to better serve the needs of buyers
and sellers utilizing our marketplace.

    INTEGRATE ENTERPRISE INFORMATION SYSTEMS INTO OUR MARKETPLACE.  We intend to
integrate our customers' information systems, such as inventory management
applications, into our marketplace system by building application interfaces. We
are developing an in-house team of information technology professionals that
will focus on providing this service to our large corporate sellers. We believe
that the integration of these systems will further simplify and automate our
customers' internal processes for buying and selling business surplus and
identifying and recording those transactions. Moreover, we believe that
integrating these information systems will provide us with a significant
competitive advantage.

THE TRADEOUT.COM MARKETPLACE

    The TradeOut.com marketplace provides a solution to the inefficiencies in
the business surplus market across a wide variety of industries by creating a
forum in which any type of business surplus can be posted and by offering a
range of sales processes through which surplus can be sold efficiently. To
provide a higher level of service, we have targeted several specific industries
in which we have developed in-depth expertise. Our strategy of offering a
solution to the business surplus problem across many industries while focusing
on several targeted industries is reflected in the breadth of our listings and
in the organization of our marketplace. We have listings in more than 100
different product categories, and our marketplace and organizational structure
focus on eight specific industry classifications:

                                   [GRAPHIC]

    TRADEOUT.COM TARGETS NEW SELLERS

    To generate listings on our site that we think buyers will find compelling,
we target a number of potential sellers of suitable products for our marketplace
through the following activities:

    - Direct customer sales calls on large key accounts in our targeted
      industries to introduce TradeOut.com as a better solution to their
      business surplus problem and to establish an ongoing business
      relationship;

    - Partnerships with traditional liquidators, dealers or brokers in our
      targeted industries, and leading electronic commerce companies that either
      manage business surplus problems or that have access to sellers with
      business surplus problems;

    - A comprehensive branding campaign to generate awareness of TradeOut.com
      among key decision makers in our targeted industries with the objective of
      encouraging listings on our site and obtaining sales leads; and

    - Presentations at industry trade shows and conferences to establish
      awareness of our marketplace and forge key business contacts.

    We typically focus our efforts on senior financial, sales, manufacturing or
supply chain executives within enterprises that may be potential sellers of
business surplus. We work with our selling customers to identify the excess
inventory and idle assets that are best suited for sale on TradeOut.com. Our
sales and customer service representatives are available to instruct customers
on how to post listings on our marketplace and how to best merchandise those
listings for successful sales.

                                       32
<PAGE>
    SELLERS POST ITEMS FOR SALE ON TRADEOUT.COM

    A seller who wishes to post an item for sale on TradeOut.com registers on
our site and completes a simple form that provides prospective buyers with
sufficient information to enable them to make a purchase decision. That
information generally includes the following:

    - an item title and description;

    - quantity available for sale;

    - location of the item;

    - category in which the seller wishes to post the item;

    - acceptable payment methods;

    - type of sale format;

    - asking price (the price below which the seller will not sell the product);

    - sale duration; and

    - photograph of the listed items.

A seller may also elect to remain anonymous to prospective buyers. In order to
increase the likelihood of selling the assets, our users may contact
TradeOut.com customer service personnel for assistance in posting and marketing
their assets.

    TradeOut.com offers sellers multiple sale formats to suit their particular
needs:

    - FIRST COME, FIRST SERVED SALE, where the seller sets an asking price and
      the first buyer to offer that price purchases the item. This type of sale
      typically enables the seller to sell the item quickly at a pre-determined
      price.

    - STANDARD AUCTION, where the seller sets an asking price, a minimum opening
      offer and sale duration. Buyers place increasing bids until the sale
      closes. At the end of the sale, the highest bidder at or above the asking
      price purchases the item. This type of sale format is designed to enable
      the seller to maximize the price for its goods by generating competition
      among buyers.

    - HIGHEST SEALED BID, where the seller sets an asking price, a minimum
      opening offer and sale duration. Buyers place sealed bids that are not
      shown to other buyers. At the end of the sale, the highest bidder at or
      above the asking price purchases the product. This type of sale enables
      sellers to attract buyers for whom confidentiality is important.

    Regardless of the type of sale format chosen, a seller also may hold a
private sale. For example, a business disposing of excess inventory may wish to
prevent channel conflict, which occurs when a company's excess inventory ends up
in the hands of unintended distributors, such as discount warehouses that sell
to the original company's own customer base at a cheaper price. Businesses can
avoid the negative consequences of channel conflict by providing us with a list
of pre-approved buyers eligible to purchase the assets for sale. Only these
buyers will be able to view and access the private listings for that seller on
our marketplace.

    TRADEOUT.COM ATTRACTS BUYERS TO THE MARKETPLACE

    To attract buyers to our Internet marketplace, we use a comprehensive sales
and marketing program that includes advertising, database-driven direct mail,
e-mail marketing and buyer tradeshows. We supplement this program with
knowledgeable trade facilitation sales personnel who identify products suitable
for purchase, direct potential buyers to the site and help manage large

                                       33
<PAGE>
transactions with key buyers in our targeted industries. Our trade facilitation
personnel also work closely with the largest sellers to ensure proper
merchandising of the items on the site and to identify past buyers from the
proprietary TradeOut.com database that might be likely buyers of the sellers'
products. If the seller has posted the sale as a private sale, our trade
facilitation personnel will work closely with the seller to contact designated
buyers and to encourage them to make offers on items in the private sale.

    BUYERS SEARCH FOR, EVALUATE AND MAKE OFFERS FOR ITEMS

    Buyers enter our Internet marketplace from our home page or via links on our
partners' Web sites. Our user-friendly interface enables the buyer to easily
gather information and make a purchase. We have instituted easy-to-use search
capabilities so buyers can minimize the amount of time required to search for
product listings. Our search engine generates lists of relevant matches to
specified search criteria. Some of the key search capabilities include search by
category, product location, key word, seller name, items posted since the user
last visited our Web site or items that must be sold immediately.

    Because some buyers may require information not contained in the product
listing, we have implemented two ways in which registered buyers may obtain
additional product information. A buyer may call or e-mail our customer service
personnel who can then contact the seller on the buyer's behalf.

    Once the registered buyer has reviewed the listing details, viewed the
photograph, if available, and resolved any open questions, the buyer may make an
offer on the listing. With an auction format, a buyer may specify the maximum
amount it is willing to pay and, utilizing our auction engine, bid automatically
in bid increments that correspond with the listing's price range. In addition,
we will automatically notify a buyer when it has been outbid during an auction.

    We also offer online proxy bidding for items being sold at traditional
industrial equipment auctions. Buyers can view items for sale in a traditional
auction, see the brochure, read the terms and conditions for the on-site auction
and make a proxy bid in advance of the auction, which will then be incorporated
into the on-site auction bidding by the auctioneer.

    Finally, our site also features a Wanted section where buyers can post items
that they are interested in purchasing. If a seller sees an item posted in the
Wanted section that it is willing to sell, the seller can click through to a
form and post the item, which triggers an automatic notification to the
potential buyer.

    SALES CLOSE AND TRADEOUT.COM COLLECTS FEES

    At the completion of a sale, if an offer meets or exceeds the asking price,
we automatically notify the buyer and seller via e-mail, and the parties
consummate the transaction offline. At that point, we send an invoice to the
seller for the commission owed on the sale. In accordance with the terms of our
user agreement, if a seller receives an offer at or above the stated asking
price, the parties are obligated to complete the transaction. Although we cannot
force the seller and buyer to complete the transaction, we can suspend them from
using our marketplace in accordance with the terms of our user agreement. The
buyer and seller independently arrange payment for and shipment of the item, in
accordance with the terms of the product listing. In the event we are notified
of a dispute between the buyer and seller, we will attempt to finalize the sale
with the current buyer or with an alternative buyer.

    We do not take possession of the products being sold or take responsibility
for the fulfillment of orders placed through our marketplace. As a result, we
are not subject to the costs and risks

                                       34
<PAGE>
associated with holding inventory, such as handling costs, leasing of warehouse
space, loss of product value and potential product damage.

    OTHER SELF-SERVICE SITE FEATURES

    We offer a variety of self-service features that make it easier for buyers
and sellers to use our Internet marketplace. For example, our My Home feature
allows the user to pre-select its asset categories of interest and the
geographic regions in which it prefers to buy. When the user logs on, the My
Home functionality automatically displays products that meet the user's
preferences. These features are especially useful to buyers that operate in a
specific industry or for which shipping costs may be prohibitive. Other features
of My Home include individual asset management reports of activity on
TradeOut.com, including items the user currently has for sale, items on which
the user currently has made offers and items the user has sold or purchased. We
also have a large Help section with answers to commonly asked questions.

    In addition, our site provides links to related service providers so users
can access, at their own expense, additional services that may be important to
the purchase or sale of the assets. These include:

    - links to shipping and logistics providers, so that buyers can obtain
      information about shipping a particular item; and

    - a link to iEscrow, an online escrow service, to provide assurance to
      buyers and sellers with respect to payment and delivery.

    OTHER INDUSTRY-SPECIFIC FEATURES

    In order to further encourage users to visit our marketplace, we have
entered into content arrangements with 24 different industry trade publications.
These publications can easily be accessed through a link from our marketplace
and provide our users with access to relevant industry news and information.
These publications include BEVERAGE WORLD, MODERN MACHINE SHOP, PAPERBOARD
PACKAGING, PROGRESSIVE GROCER and DISCOUNT MERCHANDISER.

    TRANSACTION FEES AND PRICING

    Our transaction fees are currently paid by the sellers. Sellers typically
pay a listing fee per listing. The seller defines the listing, which can
represent a single product or a series of products bundled together and sold as
one listing. In the future, we may offer sellers the option to post items on our
marketplace through a subscription arrangement instead of individual listing
fees. Under this fee structure, the seller would pay a predetermined
subscription amount, which would cover the cost of an unlimited number of
listings for the duration of the agreement.

    Upon a successful sale, which occurs when a buyer has met the seller's
asking price and the sale duration has expired, we charge the seller a
commission based on the final selling price. In the future, we may charge
sellers a graduated commission fee that takes into consideration the nature of
the transaction and the services that we provide.

    We do not currently collect fees for ancillary services or for featured site
placements, advertisements on the Web site or customized marketing programs for
sellers, but we may incorporate fees for these services in the future. As we
continue to build our user base and expand our value-added service offerings to
include features such as financing and credit, inspections, appraisals,
insurance, logistics support and escrow accounts, we may enter into revenue
sharing agreements with third-party providers of these services or offer these
services ourselves.

Services and Denergy accounted for 66.9% of our total revenues.

STRATEGIC ALLIANCES

    We are entering into strategic alliances with targeted industry anchors,
traditional market makers, traffic drivers, and ancillary service providers.

    TARGETED INDUSTRY ANCHORS.  We are developing relationships with Fortune 500
companies that we expect to become the anchors for supply in our targeted
industries by bringing a significant number of listings to our marketplace,
providing access to their traditional buyers of business surplus and promoting
our marketplace. In March 2000, we entered into an agreement with General
Electric Capital Corporation, which, together with its various business units
and affiliates, operates a business that generates a substantial amount of
business surplus and has access to a large number of buyers.

    TRADITIONAL MARKET MAKERS.  Market makers are traditional bricks-and-mortar
brokers and liquidators of business surplus. They bring both assets for sale and
access to an extensive database of buyers. By utilizing our site and services,
they obtain a more efficient means of reaching a broad group of buyers. Examples
of our market maker alliances include:

    - QUALITY KING DISTRIBUTORS, a wholesale and retail distributor of health
      and beauty care products, fragrances and grocery and pharmaceutical
      products;

    - PURITY WHOLESALE GROCERS, a wholesale distributor of grocery and general
      merchandise products; and

    - RUMARSON TECHNOLOGIES, a company that specializes in technology asset
      management and product disposition.

    TRAFFIC DRIVERS.  Traffic drivers promote our site and services to their
customers as a value-added service through their sales forces, direct marketing
efforts and Web sites. They include financial institutions, electronic commerce
and software firms, trade associations and media companies. We currently have
alliances of this type with Chase Manhattan, Merrill Lynch, PurchasePro.com, the
National Association of Wholesaler-Distributors, the Consumer Electronics
Association and DowJones.com.

    ANCILLARY SERVICE PROVIDERS.  Ancillary service providers facilitate the
sale of business surplus through our marketplace by offering a variety of pre-
and post-sale services that address the needs of the business surplus market. In
some cases, partners in the other three categories also provide ancillary
services. Current service providers include:

    - I-ESCROW, a provider of online escrow services;

    - EMERY WORLDWIDE, a transportation and logistics firm;

    - CARDINAL LOGISTICS, a logistics management company; and

    - RUMARSON TECHNOLOGIES, a technology asset management company.

SALES AND MARKETING

    Our sales and marketing activities reflect our ongoing strategy of expanding
the number of industries we serve and enhancing the depth of our expertise in
our targeted industries. We employ a combination of marketing, communications
and direct customer contacts within each of our targeted industries, with the
objective of increasing relevant product listings on our Web site, attracting
relevant buyers and generating transactions in our marketplace.

    As of December 31, 1999, our marketing organization consisted of eight
people. These individuals focus on increasing general awareness of our solution
through print advertising in leading national business publications and industry
trade publications, as well as reaching individual businesses within our
targeted industries via direct mail, e-mail, telemarketing and sales calls. We
also use a public relations media outreach program to obtain coverage of
TradeOut.com in business and trade publications. In addition, our top executives
speak at leading industry conferences to establish awareness of TradeOut.com and
to forge key business contacts with participants in these conferences.

    As of December 31, 1999, our direct sales organization consisted of 63 sales
professionals. These individuals focus their efforts on generating awareness of
the TradeOut.com solution among key decision makers within enterprises that
operate in our targeted industries and may potentially buy or sell business
surplus.

    We organize our sales professionals by targeted industy in order to
capitalize on their areas of expertise and their relationships with enterprises
in these industries. The general manager of sales for each of our targeted
industries creates a comprehensive operational plan for that industry that
relies heavily on the efforts of our sales and marketing department. In each
targeted industry, the following ongoing process occurs:

    - The general manager in charge of the targeted industry identifies the
      major manufacturing and retail organizations that represent the highest
      potential business prospects for that industry.

    - Each of the sales professionals dedicated to that industry is assigned key
      accounts with which to establish relationships. Most of our sales
      professionals have 10 to 20 years of previous experience in their
      respective industries.

    - The general manager works with our marketing personnel to design
      customized advertising and direct marketing materials and to plan a media
      schedule which includes generating coverage in trade publications for that
      industry.

    - The marketing team leverages our database of buyer information and
      coordinates marketing activities designed to drive relevant buyers in that
      industry to our marketplace.

    - As sellers in the targeted industry respond to our marketing efforts and
      register on our site, our customer service team provides ongoing support
      to the sellers by assisting with listings and identifying potential
      buyers.

    - The business development team analyzes the industry landscape and
      identifies companies that represent attractive potential partners to
      increase our expertise in the industry and to expand to other industries
      that generate high levels of business surplus.

OPERATIONS AND TECHNOLOGY

    We have built a secure user interface and transaction processing system upon
a platform using industry-standard software and hardware. The TradeOut.com
system notifies users via e-mail upon registering for the service, posting an
item for sale, being outbid and upon receiving a successful bid or sale. The
system also sends frequent status updates to any active sellers regarding the
state of their current listings and maintains information regarding user
registrations, billing accounts,

                                       37
<PAGE>
current sales and prior listings. All information is regularly extracted,
summarized and stored in a data warehouse. The system also has a search engine
that can search listings based on listing title, keywords, description, seller
name and category.

    We capture site traffic information and report on it using WebTrends and an
internally developed data warehouse. The site traffic information includes
hourly volume data, user demographic data, referring site information,
click-stream data, site activity and detailed information on the registered
users in terms of listing, bidding and purchasing activity.

    The TradeOut.com marketplace is available 24 hours a day, seven days a week.
Our system has been designed around industry standard architectures to reduce
downtime in the event of outages or catastrophic occurrences. However, we have
experienced occasional system outages that we believe will continue to occur
from time to time. These outages have stemmed from a variety of causes,
including third-party hardware and software problems, human error and general
maintenance.

    Our production systems are hosted at the Exodus facility in Waltham,
Massachusetts, which provides redundant high-bandwidth communications lines and
emergency power backup. Our systems consist of Sun database servers running
Oracle relational database management systems and a load-balanced and redundant
suite of Intel-based Compaq servers running Microsoft Internet Information
Servers on the Windows NT operating system.

    The volume of traffic on our Web site has been increasing continually,
requiring us to expand and upgrade our technology, software and network
infrastructure and to add new personnel. We may be unable to accurately project
the rate or timing of increases, if any, in the use of the TradeOut.com service
to expand and upgrade our systems and infrastructure to accommodate such
increases in a timely manner. Any failure to expand or upgrade our systems at
least as fast as the growth in demand for capacity could cause our Internet
marketplace to become unstable and possibly cease to operate for periods of
time. Unscheduled downtime could harm our business.

COMPETITION

    A number of companies provide services or products in the market for
business-to-business electronic commerce, and existing and potential customers
can choose from a variety of current and potential competitors' services.
Competition in this market is rapidly evolving and intense, and we expect
competition to further intensify in the future.

    Our Internet marketplace competes with traditional providers of services to
sellers and buyers of business surplus, such as jobbers, closeout dealers, used
machinery dealers and brokers. Many of these companies have well-established,
long-standing relationships with the same companies with which TradeOut.com
seeks to establish relationships.

    In addition, a number of companies have established online
business-to-business marketplaces for surplus assets. Some of these companies
deal exclusively in used assets; others may sell both new and surplus goods. Our
existing and potential customers can utilize a number of current and potential
competitors' services for buying and selling business surplus. The closest
current competitors are firms that provide online business-to-business
marketplaces for surplus assets in the same industry categories in which
TradeOut.com is currently focused. TradeOut.com also competes, to a lesser
degree, with consumer-oriented sites on which business-to-business transactions
are also consummated.

    Competition can be expected to intensify in the future. Several of our
competitors are well financed and could commit more resources to sales and
marketing efforts, adopt more aggressive promotional and pricing policies and
devote more resources to technology and site development than can we. In order
to respond to competitive changes in this environment, we may from time to

                                       38
<PAGE>
time make pricing, marketing or other strategic decisions that could have a
material adverse affect on our operating results.

    Barriers to entry are low. Competitors can obtain low-cost, commercially
available software that provides the same basic site functionality as
TradeOut.com. We believe that the principal competitive factors in this market
are the volume, selection and quality of assets for sale, attracting a large
population of buyers and sellers, delivering superior customer service, building
brand recognition and repeat customers, enhancing Web site functionality and
ease of use, providing value-added services, the price range of products
available on our site and reliability of our systems. We believe that we compete
favorably with respect to each of these factors. However, TradeOut.com may not
be able to compete effectively on all or any of these factors against current
and potential competitors.

INTELLECTUAL PROPERTY

    We regard the protection of our intellectual property rights to be critical
to our success. We rely or expect to rely on a combination of patent, copyright,
trademark, service mark and trade secret restrictions and contractual provisions
to protect our intellectual property rights. We require employees and
independent contractors to enter into proprietary information and
confidentiality agreements. The contractual provisions and the other steps we
have taken to protect our intellectual property may not prevent misappropriation
of our technology or deter third parties from developing similar or competing
technologies. We claim trademark rights in the marks TradeOut, TradeOut.com and
the TradeOut.com logo. We have applied for registration of the TradeOut mark in
the United States and in Argentina, Australia, Brazil, Canada, Chile, China, the
European Union, Hong Kong, Japan, Mexico, Russia, Singapore, South Africa, South
Korea and Taiwan.

    We have registered our domain name in the United States and in more than 75
foreign countries. There are, however, third parties who own foreign
registrations of the TradeOut.com domain name in some countries. These
registrations and future foreign registrations by third parties of the
TradeOut.com domain name in countries where we have not already registered our
domain name could divert traffic from our site and require us to choose other
domain names that are not easily recognizable.

    We cannot be certain that the steps we have taken to protect our
intellectual property will be adequate, that third parties will not infringe or
misappropriate our proprietary rights or that third parties will not
independently develop similar proprietary information. Any such infringement,
misappropriation or independent development could harm our future financial
results. To date there have been several instances of third parties copying our
site and we have taken steps to assert our rights against such third parties.
Additionally, effective patent, trademark, copyright and trade secret protection
may not be available in every country where we provide services. We may, at
times, have to incur significant legal costs and spend time defending our
trademarks, copyrights and, if issued, any patents. Any such defense efforts,
whether successful or not, would divert both time and resources from the
operation and growth of our business.

    There is also significant uncertainty regarding the applicability to the
Internet of existing laws regarding matters such as property ownership,
copyrights and other intellectual property rights. The vast majority of these
laws were adopted prior to the advent of the Internet and, as a result, do not
contemplate or address the unique issues of the Internet and related
technologies.

GOVERNMENT REGULATION

    As with many Internet-based businesses, we operate in an environment of
tremendous uncertainty as to potential government regulation. The Internet has
rapidly emerged as a commerce medium, and governmental agencies have not yet
been able to adapt existing regulations to its use. Future laws, regulations and
court decisions may affect the Internet or other online services,

                                       39
<PAGE>
covering issues such as user pricing, user privacy, freedom of expression,
access charges, taxation, content and quality of products and services,
advertising, intellectual property rights and information security. In addition,
because our services are offered worldwide, and we facilitate sales of goods to
businesses worldwide, foreign jurisdictions may claim that we are required to
comply with their laws. Any future regulation may have a negative impact on our
business.

    Because we are an Internet company, it is unclear in which jurisdictions we
may be deemed to be conducting business. Our failure to qualify to do business
in a jurisdiction that requires us to do so could subject us to fines and
penalties and could result in our inability to enforce agreements in that
jurisdiction.

    Numerous states have laws and regulations regarding the conduct of auctions
and the liability of auctioneers. We do not believe that these laws and
regulations, which were enacted for consumer protection many years ago, apply to
our online services. However, one or more jurisdictions may attempt to impose
these laws and regulations on our operations in the future. We may also be
subject to government regulation related to the sale of some goods over our
site.

OUR EMPLOYEES

    As of December 31, 1999, we had 127 full time employees, of whom 77 worked
in sales, marketing and business development, 32 in product development and
technology, 10 in administration and 8 in customer service. None of our
personnel are represented under collective bargaining agreements. We consider
our relations with our employees to be good. In addition, all of our employees
have the opportunity to acquire an equity stake in the company through our stock
option plan.

OUR FACILITIES

    Our corporate headquarters in Ardsley, New York currently occupy 7,810
square feet of office space under a month-to-month lease. We are in the process
of locating larger facilities to accommodate our anticipated growth.

    Our Technology and Development offices are located in Cambridge,
Massachusetts, and we have regional sales offices in the following locations:

    - Apple Valley, Minnesota;

    - Carpinteria, California;

    - Cranbury, New Jersey;

    - DeSoto, Texas;

    - Duluth, Georgia;

    - Ft. Lauderdale, Florida;

    - San Ramon, California; and

    - St. Louis, Missouri.

    We may add additional offices in the United States and in other countries.

LEGAL PROCEEDINGS

    On February 23, 2000, TradeCard, Inc. filed a complaint against us in the
United States District Court for the Southern District of New York. The
complaint alleges that we have infringed the TradeCard mark and logo. We believe
that the allegations of the complaint are without merit, and we intend to
contest them vigorously.

CLASSIFIED BOARD OF DIRECTORS

    Upon closing of this offering our board of directors will be divided into
three classes of directors serving staggered three-year terms. As a result,
approximately one-third of the board of directors will be elected each year.
This structure, when coupled with the provision of our amended and restated
certificate of incorporation authorizing the board of directors to fill vacant
directorships or increase the size of the board of directors, may delay a
stockholder from removing incumbent directors and simultaneously gaining control
of the board of directors by filling the vacancies with its own nominees.

BOARD COMMITTEES

    Upon the closing of this offering, the board of directors will have an audit
committee and a compensation committee. The audit committee will report to the
board regarding the appointment of our independent public accountants, the scope
and results of our annual audits, compliance with our accounting and financial
policies and management's procedures and policies relative to the adequacy of
our internal accounting controls. Upon the completion of the initial public
offering, the audit committee will consist of              ,              and
             .

    The compensation committee of the board of directors will review and make
recommendations to the board regarding our compensation policies and all forms
of compensation to be provided to our executive officers. In addition, the
compensation committee will review bonus and stock compensation arrangements for
all of our other employees. Upon the completion of the initial public offering,
the members of the compensation committee will be              ,
and              . No interlocking relationships will exist between our board of
directors or

                                       44
<PAGE>
compensation committee and the board of directors or compensation committee of
any other company, nor has any interlocking relationship existed in the past.

DIRECTOR COMPENSATION

    We do not currently compensate directors for attending meetings of the board
of directors or committee meetings of the board of directors, but we do
reimburse directors for their reasonable travel expenses incurred in connection
with attending these meetings.

    Under the automatic option grant program of our 2000 Stock Incentive Plan,
which is described below under "--2000 Stock Incentive Plan", and subject to the
last sentence of this paragraph, each individual who is serving as a
non-employee member of the board of directors on the date the underwriting
agreement is executed and who has not previously been in our employ will receive
at that time an option to purchase       shares of common stock with an exercise
price equal to the public offering price set forth on the cover page of this
prospectus. Each individual who first joins the board of directors after the
completion of this offering as a non-employee member of the board of directors
will also receive an option grant for       shares of common stock at the time
he or she commences service on the board of directors, provided that individual
has not otherwise been in our prior employ and has not received options to
purchase, in the aggregate, more than       shares of common stock in the last
12 months. In addition, at each annual meeting of stockholders, beginning with
the 2000 annual meeting, each individual who is to continue to serve as a
non-employee member of the board of directors will receive an option to purchase
      shares of common stock, provided that individual has served as a
non-employee board member for at least six months.

    The following table sets forth the total compensation paid during the fiscal
year ended December 31, 1999 to our Chief Executive Officer and to each of our

OPTION GRANTS IN LAST FISCAL YEAR

    The following table sets forth grants of stock options for the year ended
December 31, 1999 to each of the named executive officers. We have never granted
any stock appreciation rights. The potential realizable value is calculated
based on the term of the option at its time of grant. It is calculated assuming
that the fair market value of common stock on the date of grant appreciates at
the indicated annual rate compounded annually for the entire term of the option
and that the option is exercised and sold on the last day of its term for the
appreciated stock price. These numbers are calculated based on the requirements
of the Securities and Exchange Commission and do not reflect our estimate of
future stock price growth.

    The following table sets forth information concerning the value realized
upon exercise of options during 1999 and the number and value of unexercised
options held by each of the named executive officers at December 31, 1999. There
was no public trading market for the common stock as of December 31, 1999.
Accordingly, the values set forth below have been calculated on the basis of an

EMPLOYMENT AGREEMENTS

    We expect to enter into an employment agreement with George Samenuk, who
became our Chief Executive Officer and President effective January 28, 2000.
Mr. Samenuk's agreement is expected to provide for an annual base salary of
$250,000. If his employment is terminated for reasons other than for cause or
permanent disability, he will be entitled to receive an additional $250,000. At
the time Mr. Samenuk became an employee of TradeOut.com, we granted him options
to purchase 1,640,000 shares of our common stock at an exercise price of $2.00
per share. The options vest in 60 equal installments over a five year period. In
addition, we made a restricted stock grant to him of 410,000 shares of our
common stock in exchange for a five-year promissory note for $820,000 that bears
interest at 6.04% compounded monthly. We have agreed to grant registration
rights to Mr. Samenuk with respect to these shares.

STOCK OPTION PLANS

    1999 STOCK PLAN

    Our board of directors adopted and our stockholders approved the
Tradeout.com, Inc. 1999 Stock Plan in March 1999. The 1999 Stock Plan became
effective in March 1999 and will continue in effect for a period of ten years
unless terminated by the board of directors at an earlier date. We may grant the
following types of awards under the 1999 Stock Plan to our employees, directors,
or consultants:

    - incentive stock options;

    - nonqualified stock options; and

    - restricted stock.

    We reserved 6,567,915 shares of our common stock for issuance under the 1999
Stock Plan. As of March 14, 2000, we had options outstanding to purchase
1,579,135 shares of common stock under the 1999 Stock Plan. We had not granted
any shares of restricted stock under the 1999 Stock Plan.

    Our board of directors administers the 1999 Stock Plan and is responsible
for determining the terms and conditions of all grants of options and restricted
stock under the 1999 Stock Plan.

    If control of our company changes through, for example, an acquisition of
more than 50% of our stock by another person or company, or through a merger
with another company, and the acquiror fails to assume or replace with
equivalent awards all outstanding awards under the 1999 Stock Plan, then all
outstanding options that have not vested prior to the change of control will
immediately vest and the restrictions on any restricted stock that have not
lapsed before the change of control will immediately lapse.

    2000 STOCK INCENTIVE PLAN

    INTRODUCTION.  We intend to adopt a 2000 Stock Incentive Plan to serve as
the successor program to our 1999 Stock Plan. The 2000 plan will become
effective upon its adoption by our board, subject to approval by our
stockholders. All options outstanding under our existing 1999 Stock Plan on the
date of this offering will be transferred to the 2000 plan, and no further
option grants will be made under the 1999 plan. The transferred options will
continue to be governed by their existing principal economic terms, unless our
compensation committee decides to extend one or more features of the 2000 plan
to those options. Except as otherwise noted below, the transferred options will
have substantially the same terms as will be in effect for grants made under the
discretionary option grant program of our 2000 plan.

                                       47
<PAGE>
    SHARE RESERVE.       shares of our common stock will be reserved for
issuance under the 2000 plan. This share reserve will consist of the number of
shares we estimate will be carried over from the 1999 plan plus an additional
increase of approximately       shares. The share reserve under our 2000 plan
will automatically increase on the first trading day in January each calendar
year, beginning with calendar year 2001, by an amount equal to 2% of the total
number of shares of our common stock outstanding on the last trading day of
December in the prior calendar year, but in no event will this annual increase
exceed       shares (or such other lesser number determined by the Board). In
addition, no participant in the 2000 plan may be granted stock options or direct
stock issuances for more than       shares (      shares in the year of the
participant's hire date) of common stock in total in any calendar year.

    PROGRAMS.  Our 2000 plan will have five separate programs:

    - the discretionary option grant program, under which eligible individuals
      in our employ may be granted options to purchase shares of our common
      stock at an exercise price not less than the fair market value of those
      shares on the grant date;

    - the stock issuance program, under which eligible individuals may be issued
      shares of common stock directly, upon the attainment of performance
      milestones or the completion of a specified period of service or as a
      bonus for past services;

    - the salary investment option grant program, under which our executive
      officers and other highly compensated employees may be given the
      opportunity to apply a portion of their base salary each year to the
      acquisition of special below market stock option grants;

    - the automatic option grant program, under which option grants will
      automatically be made at periodic intervals to eligible non-employee board
      members to purchase shares of common stock at an exercise price equal to
      the fair market value of those shares on the grant date; and

    - the director fee option grant program, under which our non-employee board
      members may be given the opportunity to apply a portion of any retainer
      fee otherwise payable to them in cash each year to the acquisition of
      special below-market option grants.

    ELIGIBILITY.  The individuals eligible to participate in our 2000 plan will
include our officers and other employees, our board members and any consultants
we hire.

    ADMINISTRATION.  The discretionary option grant and stock issuance programs
will be administered by our compensation committee. This committee will
determine which eligible individuals are to receive option grants or stock
issuances under those programs, the time or times when the grants or issuances
are to be made, the number of shares subject to each grant or issuance, the
status of any granted option as either an incentive stock option or a
nonstatutory stock option under the federal tax laws, the vesting schedule to be
in effect for the option grant or stock issuance and the maximum term for which
any granted option is to remain outstanding. The compensation committee will
also have the authority to select the executive officers and other highly
compensated employees who may participate in the salary investment option grant
program in the event that program is put into effect for one or more calendar
years.

    PLAN FEATURES.  Our 2000 plan will include the following features:

    - The exercise price for any options granted under the plan may be paid in
      cash or in shares of our common stock valued at fair market value on the
      exercise date. The option may also be exercised through a same-day sale
      program without any cash outlay by the optionee.

    - The compensation committee will have the authority to cancel outstanding
      options under the discretionary option grant program, including any
      transferred options from our 1999 plan, in

                                       48
<PAGE>
      return for the grant of new options for the same or different number of
      option shares with an exercise price per share based upon the fair market
      value of our common stock on the new grant date.

    - Stock appreciation rights may be issued under the discretionary option
      grant program. These rights will provide the holders with the election to
      surrender their outstanding options for a payment from us equal to the
      fair market value of the shares subject to the surrendered options less
      the exercise price payable for those shares. We may make the payment in
      cash or in shares of our common stock. None of the options under our 1999
      plan have any stock appreciation rights.

    CHANGE IN CONTROL.  The 2000 plan will include the following change in
control provisions which may result in the accelerated vesting of outstanding
option grants and stock issuances:

    - In the event that we are acquired by merger, asset sale or sale of more
      than 50% of our voting securities by the stockholders, each outstanding
      option under the discretionary option grant program which is not to be
      assumed by the successor corporation or otherwise continued will
      immediately become exercisable for all the option shares, and all
      outstanding unvested shares will immediately vest, except to the extent
      our repurchase rights with respect to those shares are to be assigned to
      the successor corporation.

    - The compensation committee may grant options which will become exercisable
      for all the option shares (i) in the event those options are assumed in
      the acquisition but the optionee's service with us or the acquiring entity
      is subsequently terminated, or (ii) in connection with a successful tender
      offer for more than fifty percent of our outstanding voting stock or a
      change in the majority of our board through one or more contested
      elections. The vesting of any outstanding shares under our 2000 plan may
      be accelerated upon similar terms and conditions.

    The options currently outstanding under our 1999 plan currently do not have
any acceleration features.

    SALARY INVESTMENT OPTION GRANT PROGRAM.  In the event the compensation
committee decides to put this program into effect for one or more calendar
years, each of our executive officers and other highly compensated employees may
elect to reduce his or her base salary for the calendar year by an amount not
less than $    nor more than $    . Each selected individual who makes such an
election will automatically be granted, on the first trading day in January of
the calendar year for which his or her salary reduction is to be in effect, an
option to purchase that number of shares of common stock determined by dividing
the salary reduction amount by two-thirds of the fair market value per share of
our common stock on the grant date. The option will have an exercise price per
share equal to one-third of the fair market value of the option shares on the
grant date. As a result, the option will be structured so that the fair market
value of the option shares on the grant date less the exercise price payable for
those shares will be equal to the amount of the salary reduction. The option
will become exercisable in a series of twelve equal monthly installments over
the calendar year for which the salary reduction is to be in effect.

    AUTOMATIC OPTION GRANT PROGRAM.  Upon adoption and approval of the 2000
Stock Incentive Plan, each individual who first becomes a non-employee board
member at any time after the effective date of this offering will receive an
option grant to purchase       shares of common stock on the date such
individual joins the board. In addition, on the date of each annual stockholders
meeting held after the effective date of this offering, each non-employee board
member who is to continue to serve as a non-employee board member, including
each of our current non-employee board members, will automatically be granted an
option to purchase       shares of common stock, provided such individual has
served on the board for at least six months.

                                       49
<PAGE>
    Each automatic grant will have an exercise price per share equal to the fair
market value per share of our common stock on the grant date and will have a
term of 10 years, subject to earlier termination following the optionee's
cessation of board service. The option will be immediately exercisable for all
of the option shares; however, we may repurchase, at the exercise price paid per
share, any shares purchased under the option which are not vested at the time of
the optionee's cessation of board service. The shares subject to each initial
      -share automatic option grant will vest in a series of three
(3) successive annual installments upon the optionee's completion of each year
of board service over the three (3)-year period measured from the grant date.
The shares subject to each annual       -share automatic grant will vest upon
the optionee's completion of one (1) year of board service measured from the
grant date. However, the shares will immediately vest in full upon certain
changes in control or ownership or upon the optionee's death or disability while
a board member.

    DIRECTOR FEE OPTION GRANT PROGRAM.  If this program is put into effect in
the future, then each non-employee board member may elect to apply all or a
portion of any cash retainer fee for the year to the acquisition of a
below-market option grant. The option grant will automatically be made on the
first trading day in January in the year for which the non-employee board member
would otherwise be paid the cash retainer fee in the absence of his or her
election. The option will have an exercise price per share equal to one-third of
the fair market value of the option shares on the grant date, and the number of
shares subject to the option will be determined by dividing the amount of the
retainer fee applied to the program by two-thirds of the fair market value per
share of our common stock on the grant date. Accordingly, the fair market value
of the option shares on the grant date less the exercise price payable for those
shares will be equal to the portion of the retainer fee applied to that option.
The option will become exercisable in a series of twelve equal monthly
installments over the calendar year for which the election is in effect.
However, the option will become immediately exercisable for all the option
shares upon the death or disability of the optionee while serving as a board
member.

    Additional Program Features.  Our 2000 plan will also have the following
features:

    - Outstanding options under the salary investment and director fee option
      grant programs will immediately vest if we are acquired by a merger or
      asset sale or if there is a successful tender offer for more than 50% of
      our outstanding voting stock or a change in the majority of our board

required stockholder approval. The 2000 plan will terminate no later than

    2000 EMPLOYEE STOCK PURCHASE PLAN

    We intend to adopt a 2000 Employee Stock Purchase Plan. Subject to approval
by our stockholders, the plan will become effective immediately upon the signing
of the underwriting agreement for this offering. The plan is designed to allow
our eligible employees to purchase shares of common stock, at semi-annual
intervals, with their accumulated payroll deductions.

                                       50
<PAGE>
    SHARE RESERVE.       shares of our common stock will initially be reserved
for issuance. The reserve will automatically increase on the first trading day
in January of each calendar year, beginning in calendar year 2001, by an amount
equal to the total number of shares of our common stock issued under the plan in
the prior calendar year. In no event will any such annual increase exceed
shares.

    OFFERING PERIODS.  The plan will have a series of successive offering
periods, each with a maximum duration of 24 months. The initial offering period
will start on the date the underwriting agreement for this offering is signed
and will end on the last business day in January 2002. The next offering period
will start on the first business day in February 2002, and subsequent offering
periods will set by our compensation committee.

    ELIGIBLE EMPLOYEES.  Individuals scheduled to work more than 20 hours per
week for more than 5 calendar months per year may join an offering period on the
start date or any semi-annual entry date within that period. Semi-annual entry
dates will occur on the first business day of February and August each year.
Individuals who become eligible employees after the start date of an offering
period may join the plan on any subsequent semi-annual entry date within that
offering period.

    PAYROLL DEDUCTIONS.  A participant may contribute up to 15% of his or her
base salary through payroll deductions, and the accumulated deductions will be
applied to the purchase of shares on each semi-annual purchase date. The
purchase price per share will be equal to 85% of the fair market value per share
on the participant's entry date into the offering period or, if lower, 85% of
the fair market value per share on the semi-annual purchase date. Semi-annual
purchase dates will occur on the last business day of January and July each
year. However, a participant may not purchase more than   shares on any purchase
date, and not more than   shares may be purchased in total by all participants
on any purchase date. Our compensation committee will have the authority to
change these limitations for any subsequent offering period.

    RESET FEATURE.  If the fair market value per share of our common stock on
any purchase date is less than the fair market value per share on the start date
of the two-year offering period, then that offering period will automatically
terminate, and a new two-year offering period will begin on the next business
day. All participants in the terminated offering will be transferred to the new
offering period.

    CHANGE IN CONTROL.  Should we be acquired by merger or sale of substantially
all of our assets or more than fifty percent of our voting securities, then all
outstanding purchase rights will automatically be exercised immediately prior to
the effective date of the acquisition. The purchase price will be equal to 85%
of the market value per share on the participant's entry date into the offering
period in which an acquisition occurs or, if lower, 85% of the fair market value
per share immediately prior to the acquisition.

    PLAN PROVISIONS.  The following provisions will also be in effect under the
plan:

    The plan will terminate no later than the last business day of
January 2010. The board may at any time amend, suspend or discontinue the plan.
However, certain amendments may require stockholder approval.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

    TradeOut.com's amended and restated certificate of incorporation, which will
become effective upon the closing of this offering, will authorize the issuance
of up to 200,000,000 shares of common stock, par value $.0001 per share, and
10,000,000 shares of preferred stock, par value $.0001 per share, the rights and
preferences of which may be established from time to time by our board of
directors. As of March 14, 2000, 37,043,030 shares of common stock were
outstanding, assuming the conversion of all shares of preferred stock
outstanding as of that date into common stock. As of March 14, 2000, we had 89
stockholders.

COMMON STOCK

    Holders of our common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders, including the
election of directors. They do not have cumulative voting rights. Subject to
preferences that may be applicable to any then-outstanding preferred stock,
holders of our common stock are entitled to receive ratably dividends, if any,
as may be declared by the board of directors out of legally available funds. In
case of a liquidation, dissolution or winding up of TradeOut.com, the holders of
common stock will be entitled to share ratably in the net assets legally
available for distribution to shareholders after payment of all of our
liabilities and any preferred stock then outstanding. Holders of common stock
have no preemptive or conversion rights or other subscription rights. There are
no redemption or sinking fund provisions applicable to the common stock. The
rights, preferences and privileges of holders of common stock are subject to the
rights of the holders of shares of any series of preferred stock that we may
designate and issue in the future. After the closing of this offering, there
will be no shares of preferred stock outstanding.

PREFERRED STOCK

    Under our amended and restated certificate of incorporation, our board of
directors will have the authority, without further action by the stockholders,
to issue from time to time, shares of preferred stock in one or more series. The
board of directors may fix the number of shares, designations, preferences,
powers and other special rights of the preferred stock. The preferences, powers,
rights and restrictions of different series of preferred stock may differ. The
issuance of preferred stock could decrease the amount of earnings and assets
available for distribution to holders of common stock or affect adversely the
rights and powers, including voting rights, of the holders of common stock. Such
issuance may also have the effect of delaying, deferring or preventing a change
in control of TradeOut.com. We have no current plans to issue any shares of
preferred stock.

COMMON STOCK WARRANTS

    As of the date of this prospectus, the holders of our Series A preferred
stock, Series C preferred stock and Series D preferred stock hold warrants to
purchase an aggregate of up to 13,533,445 shares of our common stock at exercise
prices ranging from $2.00 to $8.94 per share. All of the warrants held by the
holders of the Series A preferred stock and Series C preferred stock expire
90 days following the closing of this offering. The warrant held by the holder
of the Series D preferred stock expires six years from the launch of our
strategic alliance with GE Capital. The holders of our Series E preferred stock
hold warrants to purchase a number of shares of our common stock to be
determined upon the closing of this offering based upon the fully diluted
capitalization of TradeOut.com on that date. The exercise price for these
warrants will be equal to the initial public offering price. In 1999, we issued
warrants to purchase 14,050 shares of our

                                       57
<PAGE>
common stock, at an exercise price of $0.02 per share, in exchange for
consulting services provided to us. In 2000, we issued a warrant to purchase
2,000 shares of common stock at an exercise price of $0.02 per share to a
customer in connection with its listings on TradeOut.com and a warrant to
purchase 10,000 shares of common stock at an exercise price of $2.00 per share
in exchange for consulting services provided to us. These warrants were fully
exercisable at the date of grant and have three year terms. In 2000, we issued
warrants to purchase an aggregate of up to 3,409,394 shares of our common stock
at an exercise price of $2.00 per share to our strategic partners. Each warrant
vests only upon achievement of certain revenue criteria. The warrants are not
exercisable until after this offering, and the warrants have terms ranging from
one to five years.

REGISTRATION RIGHTS

    Under an investors' rights agreement, the holders of 12,660,123 shares of
our capital stock, the holders of up to 13,533,445 shares of capital stock
issuable upon exercise of warrants are entitled to registration rights in
connection with the registration of their shares under the Securities Act of
1933, subject to various limitations. The holders of the Series E Preferred
Stock also have registration rights with respect to the shares issuable upon
exercise of their warrants, the number of which will be determined upon closing
of this offering. At any time after we become eligible to file a registration
statement on Form S-3, the holders of these shares may require us to file up to
four registration statements under the Securities Act of 1933 on Form S-3 in
connection with their shares of common stock. In addition, GE Capital Equity
Investments has the right, beginning six months after the closing of this
offering, to require that we register the shares of common stock issued upon
conversion of the Series D Preferred Stock and the warrant held by GE Capital
Equity Investments. These registration rights are subject to conditions and
limitations, among them the right of underwriters of an offering to limit the
number of shares of common stock held by securityholders with registration
rights to be included in a registration. Generally, we are required to bear all
expenses of all of these registrations, except underwriting discounts and
selling commissions. Registration of any shares of common stock held by security
holders with registration rights would result in shares becoming freely tradable
without restriction under the Securities Act of 1933 immediately upon
effectiveness of such registration.

ANTI-TAKEOVER EFFECTS OF DELAWARE LAW AND OUR AMENDED AND RESTATED CERTIFICATE
OF INCORPORATION AND BYLAWS

    Provisions of our amended and restated certificate of incorporation and
amended and restated bylaws to be effective upon closing of this offering, which
are summarized in the following paragraphs, may have an anti-takeover effect and
may delay, defer or prevent a tender offer or takeover attempt that a
stockholder might consider in its best interest, including those attempts that
might result in a premium over the market price for the shares held by
stockholders.

    CLASSIFIED BOARD OF DIRECTORS

    Our board of directors will be divided into three classes of directors
serving staggered three-year terms. As a result, approximately one-third of the
board of directors will be elected each year. These provisions, when coupled
with the provision of our amended and restated certificate of incorporation
authorizing the board of directors to fill vacant directorships or increase the
size of the board of directors, may delay a stockholder from removing incumbent
directors and simultaneously gaining control of the board of directors by
filling the vacancies created by such removal with its own nominees.

                                       58
<PAGE>
    STOCKHOLDER ACTION; SPECIAL MEETING OF STOCKHOLDERS

    Our amended and restated certificate of incorporation will eliminate the
ability of stockholders to act by written consent. It will further provide that
special meetings of our stockholders may be called only by the chairman of the
board of directors or a majority of the board of directors.

    ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTOR
     NOMINATIONS

    Our amended and restated by-laws will provide that stockholders seeking to
bring business before an annual meeting of stockholders, or to nominate
candidates for election as directors at an annual meeting of stockholders, must
provide timely notice thereof in writing. To be timely, a stockholder's notice
must be received at our principal executive offices not less than 60 days nor
more than 90 days prior to the anniversary date of the immediately preceding
annual meeting of stockholders. In the event that the annual meeting is called
for a date that is not within 30 days before or after the anniversary date, in
order to be timely, notice from the stockholder must be received no later than
the tenth day following the date on which notice of the annual meeting was
mailed to stockholders or made public, whichever occurred earlier. In the case
of a special meeting of stockholders called for the purpose of electing
directors, notice by the stockholder in order to be timely must be received not
later than the close of business on the tenth day following the day on which
notice was mailed or public disclosure of the date of the special meeting was
made, whichever first occurs. Our amended and restated by-laws also will specify
certain requirements as to the form and content of a stockholder's notice. These
provisions may preclude stockholders from bringing matters before an annual or
special meeting of stockholders or from making nominations for directors at
these meetings.

    AUTHORIZED BUT UNISSUED SHARES

    The authorized but unissued shares of common stock and preferred stock are
available for future issuance without stockholder approval, subject to
compliance with applicable Nasdaq National Market requirements. These additional
shares may be utilized for a variety of corporate purposes, including future
public offerings to raise additional capital, corporate acquisitions and
employee benefit plans. The existence of authorized but unissued shares of
common stock and preferred stock could render more difficult or discourage an
attempt to obtain control of us by means of a proxy contest, tender offer,
merger or otherwise.

    The Delaware General Corporation Law provides generally that the affirmative
vote of a majority of the shares entitled to vote on any matter is required to
amend a corporation's certificate of incorporation or bylaws, unless a
corporation's certificate of incorporation or bylaws, as the case may be,
requires a greater percentage. Our amended and restated certificate of
incorporation imposes supermajority vote requirements in connection with various
business combination transactions and the amendment of various provisions of our
amended and restated certificate of incorporation and amended and restated
bylaws, including those provisions relating to the classified board of
directors, action by written consent and special meetings by stockholders.

TRANSFER AGENT AND REGISTRAR

    The Transfer Agent and Registrar for TradeOut.com's common stock will be
American Stock Transfer & Trust Company, New York, New York.

LISTING

    We intend to apply to list our common stock on the Nasdaq National Market
under the trading symbol "TOUT".

                        SHARES ELIGIBLE FOR FUTURE SALE

    Sales of substantial amounts of our common stock in the public market could
adversely affect prevailing market prices of our common stock. Furthermore,
since no shares held by our existing stockholders will be available for sale
shortly after this offering because of the contractual and legal restrictions on
resale described below, sales of substantial amounts of common stock in the
public market after these restrictions lapse could adversely affect the
prevailing market price and our ability to raise equity capital in the future.

    Upon completion of this offering, we will have outstanding an aggregate of
      shares of our common stock, assuming no exercise of the Underwriters'
over-allotment option and no exercise of outstanding options. Of these shares,
all of the shares sold in this offering will be freely tradable without
restriction or further registration under the Securities Act, unless the shares
are purchased by "affiliates" as that term is defined in Rule 144 under the
Securities Act. The remaining              shares of common stock held by
existing stockholders are "restricted securities" as that term is defined in
Rule 144 under the Securities Act. Restricted securities may be sold in the
public market following registration or pursuant to an exemption from
registration under Rule 144 promulgated under the Securities Act, which rules
are summarized below.

LOCK-UP AGREEMENTS

    All of our officers, directors and all of our stockholders have signed
lock-up agreements under which they agreed not to transfer or dispose of,
directly or indirectly, or hedge any shares of common stock or any securities
convertible into or exercisable or exchangeable for shares of common stock, for
a period of 180 days after the date of this prospectus. Transfers or
dispositions can be made sooner with the prior written consent of Goldman,
Sachs & Co.

    Subject to the provisions of Rule 144, 144(k) and 701, restricted shares
totaling       will be available for sale in the public market, subject in the
case of shares held by affiliates to the volume restrictions contained in those
rules, 180 days after the date of this prospectus.

RULE 144

    In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
common stock for at least one year, including the holding period of any prior
owner other than an affiliate, would be entitled to sell within any three-month
period a number of shares that does not exceed the greater of:

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

    - the average weekly trading volume of the common stock on the Nasdaq
      National Market during the four calendar weeks preceding the filing of a
      notice on Form 144 with respect to such sale.

    Sales under Rule 144 are also subject to certain manner of sale provisions
and notice requirements and to the availability of current public information
about us.

RULE 144(K)

    Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an affiliate, is
entitled to sell those shares without complying with the manner of sale, public
information, volume

                                       60
<PAGE>
limitation or notice provisions of Rule 144. Therefore, unless otherwise
restricted, "144(k) shares" may be sold immediately upon the completion of this
offering.

RULE 701

    In general, under Rule 701 of the Securities Act as currently in effect,
each of our employees, consultants or advisors who purchases shares from us
prior to our public offering pursuant to securities issued under a compensatory
stock plan or other written agreement is eligible to resell such shares 90 days
after the effective date of this offering in reliance on Rule 144, but without
compliance with some of the restrictions, including the holding period,
contained in Rule 144.

REGISTRATION RIGHTS

    Upon completion of this offering, the holders of 12,660,123 shares of our
capital stock, the holders of up to 13,533,445 shares of capital stock issuable
upon exercise of warrants and the holders of the warrants issued in connection
with the sale of our Series E preferred stock, will be entitled to registration
rights under the Securities Act of 1933, as amended.

STOCK PLANS

    Promptly after this offering, we intend to file a registration statement
under the Securities Act covering              shares of common stock reserved
for issuance under our 2000 stock plans. This registration statement is expected
to be filed as soon as practicable after the completion of this offering.

    At              , 2000, options to purchase       shares were issued and
outstanding under our plan. Once this registration statement has been filed, all
of these shares will be eligible for sale in the public market from time to time
subject to vesting provisions, Rule 144 volume limitations applicable to our
affiliates and, in the case of some of the options, the expiration of lock-up
agreements.

             shares from TradeOut.com to cover such sales. They may exercise
that option for 30 days. If any shares are purchased pursuant to this option,
the underwriters will severally purchase shares in approximately the same
proportion as set forth in the table above.

    Shares sold by the underwriters to the public will initially be offered at
the initial public offering price set forth on the cover of this prospectus. Any
shares sold by the underwriters to securities dealers may be sold at a discount
of up to $      per share from the initial public offering price. Any such
securities dealers may resell any shares purchased from the underwriters to
certain other brokers or dealers at a discount of up to $      per share from
the initial public offering price. If all the shares are not sold at the initial
public offering price, the representatives may change the offering price and the
other selling terms.

    TradeOut.com, its directors, officers, employees and other holders have
agreed with the underwriters not to dispose of or hedge any of their common
stock or securities convertible into or exchangeable for shares of common stock
during the period from the date of this prospectus continuing through the date
180 days after the date of this prospectus, except with the prior written
consent of Goldman, Sachs & Co. See "Shares Eligible for Future Sale" for a
discussion of certain transfer restrictions.

    Prior to this offering, there has been no public market for the shares. The
initial public offering price will be negotiated among TradeOut.com and the
representatives. Among the factors to be considered in determining the initial
public offering price of the shares, in addition to prevailing market
conditions, will be TradeOut.com's historical performance, estimates of the
business potential and earnings prospects of TradeOut.com, an assessment of
TradeOut.com's management and the consideration of the above factors in relation
to the market valuation of companies in related businesses.

                                       62
<PAGE>
    TradeOut.com intends to apply for quotation of the common stock on the
Nasdaq National Market under the symbol "TOUT".

    In connection with the offering, the underwriters may purchase and sell
shares of common stock in the open market. These transactions may include short
sales, stabilizing transactions and purchases to cover positions created by
short sales. Short sales involve the sale by the underwriters of a greater
number of shares than they are required to purchase in the offering. Stabilizing
transactions consist of certain bids or purchases made for the purpose of
preventing or retarding a decline in the market price of the common stock while
the offering is in progress.

    The underwriters may also impose a penalty bid. This occurs when a
particular underwriter repays to other underwriters a portion of the
underwriting discount received by it because the representatives have
repurchased shares sold by or for the account of such underwriter in stabilizing
or short covering transactions.

    These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of the common stock. As a result, the price of the
common stock may be higher than the price that otherwise might exist in the open
market. If these activities are commenced, they may be discontinued by the
underwriters at any time. These transactions may be effected on the Nasdaq
National Market, in the over-the-counter market or otherwise.

    At the request of TradeOut.com, the underwriters are reserving up to
             shares of common stock for sale at the initial public offering
price to officers, directors, employees, business associates and persons
affiliated with TradeOut.com through a directed share program. The number of
shares of common stock available for sale to the general public in the public
offering will be reduced to the extent these persons purchase these reserved
shares. Any shares not so purchased will be offered by the underwriters to the
general public on the same basis as other shares offered hereby.

    The underwriters do not expect sales to discretionary accounts to exceed
five percent of the total number of shares offered.

    At the request of TradeOut.com, the underwriters expect to reserve, at the
initial public offering price, up to 300,000 shares of common stock for sale to
an affiliate of GE Capital and up to      shares of common stock for sale to
directors and employees of TradeOut.com. GE Capital is a stockholder and
strategic alliance partner of TradeOut.com.

    TradeOut.com estimates that its share of the total expenses of the offering,
excluding underwriting discounts and commissions, will be approximately $      .

    TradeOut.com has agreed to indemnify the several underwriters against
certain liabilities, including liabilities under the Securities Act of 1933.

    On March 14, 2000, H&Q Access Technology Partners, L.P., an affiliate of
Chase Securities Inc., purchased 98,224 shares of TradeOut.com's Series E
preferred stock, which will be converted into 49,112 shares of common stock upon
consummation of this offering. The aggregate purchase price paid for these
shares was $1,000,000.

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Stockholders of
  TradeOut.com, Inc.

    We have audited the accompanying balance sheets of TradeOut.com, Inc. (the
"Company") as of December 31, 1998 and 1999, and the related statements of
operations, changes in stockholders' equity and cash flows for the period from
December 11, 1998 (date of inception) to December 31, 1998 and the year ended
December 31, 1999. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of TradeOut.com, Inc. at
December 31, 1998 and 1999, and the results of its operations and its cash flows
for the period from December 11, 1998 (date of inception) to December 31, 1998
and the year ended December 31, 1999 in conformity with accounting principles
generally accepted in the United States.

                         NOTES TO FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

    TradeOut.com, Inc. ("TradeOut" or the "Company"), was incorporated in the
State of Delaware on December 11, 1998 and launched its Web site in April 1999.
The Company is a business-to-business Internet marketplace for buyers and
sellers of business surplus.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and the
footnotes thereto. Actual results could differ from those estimates.

CASH EQUIVALENTS

    The Company considers all financial instruments with a maturity of three
months or less when purchased to be cash equivalents. Such amounts are stated at
cost, which approximates market value.

FAIR VALUES OF FINANCIAL INSTRUMENTS

    The carrying amounts reported in the balance sheets for cash and cash
equivalents, accounts receivable, and accounts payable are stated at cost, which
approximates fair value.

PROPERTY AND EQUIPMENT

    Property and equipment, including those assets acquired under capital
leases, are stated at cost and depreciated or amortized on the straight-line
method over the shorter of the lease term or the estimated useful lives of the
assets, which are generally five years or less.

SOFTWARE DEVELOPMENT COSTS

    In accordance with Statement of Position No. 98-1, "Accounting for the Costs
of Computer Software Developed or Obtained for Internal Use", the Company
capitalized approximately $554,000 of costs attributable to the development of
its Web site. Amortization of these capitalized software development costs
amounted to $138,000 for the year ended December 31, 1999.

REVENUE RECOGNITION

    The Company derives its revenues primarily from sales commissions and, to a
lesser extent, listing fees, both of which are paid by sellers. Sales
commissions represent a percentage of the purchase price the seller pays upon
completion of a transaction. Sales commissions are recognized at the time an
item is sold or the sale or auction for the item is successfully concluded, net
of provisions for sales returns. Revenues from listing fees are recognized over
the period of time that the related merchandise is listed on the Company's Web
site.

                               TRADEOUT.COM, INC.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    The Company does not take possession or ownership of either the item sold or
the buyer's payment for the item. The Company has no procurement, carrying or
shipping costs. The Company does not charge fees to buyers and to date has
chosen not to sell advertising on its Web site.

RESEARCH AND DEVELOPMENT COSTS

    Research and development costs consist of expenses incurred by the Company
to enhance, manage, maintain and operate its Web site. All such research and
development costs are expensed as incurred.

SALES AND MARKETING COSTS

    Sales and marketing costs primarily consist of compensation for sales and
marketing personnel, advertising, trade show and other promotional costs and are
expensed as incurred.

STOCK-BASED COMPENSATION

    The Company grants stock options generally for a fixed number of shares to
certain employees with an exercise price equal to or below the fair value of the
shares at the date of grant. The Company accounts for this stock-based employee
compensation in accordance with Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees", ("APB 25") and, accordingly,
recognizes compensation expense only if the fair value of the underlying common
stock exceeds the exercise prices of the stock option on the date of grant.

    In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123"), which provides an alternative to APB 25 in
accounting for stock-based compensation. As permitted by SFAS 123, the Company
accounts for stock-based compensation in accordance with APB 25 and has elected
the pro forma disclosure alternative permitted by SFAS 123.

INCOME TAXES

    The Company uses the liability method of accounting for income taxes,
whereby deferred income taxes are provided on items recognized for financial
reporting purposes over different periods than for income tax purposes.
Valuation allowances are provided when the expected realization of tax assets
does not meet a more likely than not criteria.

COMPUTATION OF NET LOSS PER SHARE

    The Company calculates earnings per share in accordance with SFAS No. 128,
"Computation of Earnings Per Share" and SEC Staff Accounting Bulletin No. 98.
Accordingly, basic earnings per share are computed using the weighted average
number of common and dilutive common equivalent shares outstanding during the
period. Common equivalent shares consist of the incremental common shares
issuable upon the conversion of the Preferred Stock (using the if-converted
method) and shares issuable upon the exercise of stock options and warrants
(using the treasury stock method); common equivalent shares are excluded from
the calculation if their effect is anti-dilutive.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
CONCENTRATION OF CREDIT RISK, MAJOR CUSTOMERS AND GEOGRAPHIC INFORMATION

    Financial instruments which potentially subject the Company to a
concentration of credit risk consist of cash and cash equivalents and accounts
receivable. The Company maintains the majority of its cash and cash equivalents
with one financial institution.

    The Company generates revenue principally from customers located in North
America, many of which are large multi-national organizations. Two customers
accounted for 67% of the Company's revenues for the year ended December 31,
1999. Accounts receivable are due principally from two customers, whose combined
account balances amount to 76% of accounts receivable at December 31, 1999. The
Company routinely assesses the financial strength of its customers and does not
require collateral or other security to support customer receivables. Credit
losses are provided for in the financial statements in the form of an allowance
for doubtful accounts.

2. PROPERTY AND EQUIPMENT

    Property and equipment consists of the following at December 31, 1999:

</TABLE>

    Office equipment includes assets acquired under capital leases at a cost of
$121,762 and accumulated depreciation of $40,587.

3. STOCKHOLDERS' EQUITY

STOCK SPLITS

    In March 1999, the Company effected a three hundred-for-one stock split of
the common stock by which each share of the Company's common stock outstanding
prior to the split was converted into three hundred shares of the Company's
common stock. In August 1999, the Company effected a further two-for-one stock
split of the common stock by which each share of the Company's common stock
outstanding prior to the split was converted into two shares of the Company's
common stock. All common stock share information in the accompanying financial
statements has been adjusted to reflect the three hundred-for-one stock split
and the two-for-one stock split. All preferred stock conversion rights
information in the accompanying financial statements has been adjusted to
reflect both of these common stock splits.

COMMON STOCK

    In December 1998, the Company received upon its initial capitalization
$170,750, of which $60,750 was a subscription receivable and $10,000 represented
services provided to the Company, in exchange for which it issued 31,170,000
shares of common stock. The subscription receivable

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

3. STOCKHOLDERS' EQUITY (CONTINUED)
was collected in full in January and February 1999. In January and
February 1999, the Company issued an additional 7,302,000 shares of common stock
in exchange for approximately $1,217,000.

PREFERRED STOCK

SERIES A PREFERRED STOCK

    In April and May 1999, the Company authorized 4,300,000 and issued 2,931,200
shares of Series A preferred stock, par value $.0001 per share (the "Series A
preferred stock"), for a purchase price of $2.43 per share. At the same time,
the Company issued warrants for an aggregate purchase price of $72,000 (the
"Series A warrants") to purchase an additional 7,544,908 shares of the Company's
common stock at an exercise price of $3.98 per share.

    The exercise price of the Series A warrants may be adjusted to account for
stock splits or other subdivisions, combinations or issuances such that the
aggregate purchase price payable for the total shares purchasable remains the
same. Each share of Series A preferred stock is convertible into two shares of
common stock. The Series A preferred stock has certain preferential rights upon
liquidation and was entitled to an 8% cumulative dividend payable in additional
Series A preferred stock shares. Generally, the holders of the Series A
preferred stock have the same voting rights as the holders of the Company's
common stock, except with regard to the election of the Board of Directors. The
holders of the Series A preferred stock, voting as a separate class, are
currently entitled to elect one individual to the Board of Directors.

    In October 1999, the Company declared and paid an 8% cumulative dividend in
additional Series A preferred stock. This resulted in the issuance of 114,714
additional shares of Series A preferred stock. Upon issuance of the Company's
Series C preferred stock, the rights of the Series A preferred stock holders
were amended to eliminate the 8% cumulative dividend.

SERIES B PREFERRED STOCK

    In August 1999, the Company issued 953,361 shares of Series B preferred
stock, par value $.0001 per share (the "Series B preferred stock"), for a
purchase price of $8.01 per share. Each share of Series B preferred stock is
convertible into two shares of common stock. The Series B preferred stock has
certain preferential rights upon liquidation. Generally, the holders of the
Series B preferred stock have the same voting rights as the holders of the
Company's common stock, except with regard to the election of the Board of
Directors.

SERIES C PREFERRED STOCK

    In 1999, the Company issued 9,288,273 shares of Series C preferred stock,
par value $.0001 per share (the "Series C preferred stock"), for a purchase
price of $2.23 per share. At the same time, the Company issued warrants, for an
aggregate purchase price of $63,959 (the "Series C warrants"), to purchase an
additional 14,736,981 shares of the Company's common stock at an exercise price
of $4.47 per share. Each share of Series C preferred stock is convertible into
one share of our common stock. The exercise price of the Series C warrants may
be adjusted to account for stock splits or other subdivisions, combinations or
issuances such that the aggregate purchase price payable for the total shares
purchasable remains the same. The Series C preferred stock has certain
preferential rights upon liquidation. Generally, the holders of the Series C

common stock, except with regard to the election of the Board of Directors. The
holders of the Series C preferred stock, voting as a separate class, are
currently entitled to elect one individual to the Board of Directors.

WARRANTS

    In 1999, the Company issued warrants to purchase 28,100 shares of its common
stock in exchange for certain consulting services provided to the Company. These
warrants were fully vested at the date of grant and are exercisable for a period
of three years at $0.01 per share. The warrants were valued at approximately
$63,000, which the Company determined to be the value of the services received,
and were charged to expense in 1999.

RESERVED SHARES

    The Company has reserved 39,596,812 shares of common stock to be issued upon
the conversion of the Series A, B and C preferred stock, the exercise of the
Series A warrants and the Series C warrants, and warrants issued in exchange for
certain consulting services.

5. STOCK OPTION PLAN

    In 1999, the Company approved and adopted the TradeOut.com, Inc. 1999 Stock
Option Plan (the "1999 Plan") and reserved 13,135,830 shares of its common stock
for issuance pursuant to the 1999 Plan. The 1999 Plan provides for the grant of
stock options to qualified employees and consultants of the Company. Options are
granted with an exercise price equal to the Company's then current estimate of
the fair market value of its common stock. The options are exercisable for a
period not to exceed ten years. The vesting schedule is determined at the date
of each grant. Stock options granted pursuant to the 1999 Plan generally vest
over periods of between three and five years.

    In connection with options granted in 1999, the Company recorded deferred
compensation of $867,773. The Company has, for financial reporting purposes,
used a fair market value of $0.17 to $3.00 per share from January 1, 1999
through December 31, 1999 to record deferred compensation. This value is based
upon analyses prepared by the Company. Deferred compensation is being amortized
over the vesting period of the options granted. The amount recognized as expense
during the year ended December 31, 1999 was approximately $91,000.

STRATEGIC BUSINESS ALLIANCES

    During 1999, the Company entered into several strategic business alliance
agreements whereby the Company pays a sales commission to its strategic alliance
partners based on a percentage of the commission revenue or gross sales dollars
arising from the successful sale of merchandise listed or referred by the
strategic partner.

8. SUBSEQUENT EVENTS AND PRO FORMA ADJUSTMENTS

SERIES D PREFERRED STOCK

    In March 2000, the Company agreed to issue 5,577,825 shares of Series D
preferred stock (the "Series D preferred stock") for approximately $15,000,000,
a stated value of approximately $2.69 per share. The Company also agreed to
issue warrants to purchase up to 4,785,000 shares of its common stock (the
"Series D warrants") at an exercise price of $1.00 per share. Each share of
Series D preferred stock is convertible into one share of our common stock. The
issuance of the Series D warrants is dependent upon the holder of the Series D
preferred stock, which has also entered into a contractual strategic business
relationship with the Company, meeting certain performance criteria related to
target sales levels. The Company will recognize a "stock-based strategic
alliance cost" for the estimated fair market value of the warrants in each
quarter in which the sales target is achieved and the warrants are earned. The
charge will be based on the fair market value of the warrants at the time the
quarterly sales target is achieved or achievement is probable. Such charges
could be significant.

SERIES E PREFERRED STOCK

    In March 2000, the Company agreed to issue 2,455,588 shares of Series E
preferred stock (the "Series E preferred stock") for approximately $25,000,000,
a stated value of approximately $10.18 per share. The Company also agreed to
issue warrants (the "Series E warrants") to purchase shares of its common stock,
with the total number of shares that may be purchased upon exercise to be
determined based on a formula related to the price of the Company's common
stock. Each share of Series E preferred stock is convertible into one share of
our common stock. The Series E warrants will have an exercise price equal to the
Initial Public Offering price per share of the Company's common stock.

STRATEGIC BUSINESS ALLIANCES

common stock at $1.00 per share. The vesting of these warrants is conditioned
upon the attainment of certain target sales levels over the terms of the
strategic alliance agreements.

    The Company will recognize a "stock-based strategic alliance cost" for the
estimated fair market value of the warrants in each quarter in which the sales
target is achieved and the warrants are earned. The charge will be based on the
fair market value of the warrants at the time the quarterly sales target is
achieved or achievement is probable. Such charges could be significant.

EMPLOYMENT AGREEMENT

    The Company expects to enter into an employment agreement with its current
Chief Executive Officer and President, which is expected to provide for an
annual base salary of $250,000 and, if the agreement were to be terminated for
reasons other than for cause or permanent disability, an additional payment of
$250,000. In connection with commencement of his employment, the Chief Executive
Officer and President received a ten-year option to acquire 3,280,000 shares of
the Company's common stock, representing 4% of the outstanding common stock.
These options may be exercised at a price of $1.00 per share and vest in sixty
equal installments over a five-year period. The Company made a restricted stock
grant to the Chief Executive Officer and President of 820,000 shares of its
common stock in return for a five-year promissory note for $820,000 that bears
interest at 6.04%, compounded monthly, payable at maturity.

PRO FORMA FINANCIAL INFORMATION

    Upon the completion of an initial public offering at a per share price to
the public of not less than       and in which the gross proceeds paid by the
public are at least $      , all outstanding preferred shares will automatically
be converted into shares of common stock in the manner described in Note 3. The
pro forma balance sheet at December 31, 1999 gives effect to such conversion as
if it occurred on that date. The pro forma loss for the year ended December 31,
1999 gives effect to the conversion of such shares as if it occurred on the
dates the shares were issued.

COMMON STOCK

    In March 2000, the Company increased the number of authorized shares of
common stock to 125,000,000.

LITIGATION

    On February 23, 2000, a complaint was filed against the Company alleging
trademark and logo infringement. The Company believes that the allegations of

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The registrant's Amended and Restated Certificate of Incorporation in effect
as of the date hereof (the "Certificate") provides that, except to the extent
prohibited by the Delaware General Corporation Law, as amended (the "DGCL"), the
registrant's directors shall not be personally liable to the registrant or its
stockholders for monetary damages for any breach of fiduciary duty as directors
of the registrant. Under the DGCL, the directors have a fiduciary duty to the
registrant which is not eliminated by this provision of the Certificate and, in
appropriate circumstances, equitable remedies such as injunctive or other forms
of nonmonetary relief will remain available. In addition, each director will
continue to be subject to liability under the DGCL for breach of the director's
duty of loyalty to the registrant, for acts or omissions which are found by a
court of competent jurisdiction to be not in good faith or involving intentional
misconduct, for knowing violations of law, for actions leading to improper
personal benefit to the director, and for payment of dividends or approval of
stock repurchases or redemptions that are prohibited by the DGCL. This provision
also does not affect the directors' responsibilities under any other laws, such
as the federal securities laws or state or federal environmental laws. The
registrant has liability insurance for its officers and directors.

    Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers, provided that this provision
shall not eliminate or limit the liability of a director: (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders; (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law; (iii) arising under Section 174 of the DGCL; or
(iv) for any transaction from which the director derived an improper personal
benefit. The DGCL provides further that the indemnification permitted thereunder
shall not be deemed exclusive of any other rights to which the directors and
officers may be entitled under the corporation's bylaws, any agreement, a vote
of stockholders or

                                      II-1
<PAGE>
otherwise. The Certificate eliminates the personal liability of directors to the
fullest extent permitted by Section 102(b)(7) of the DGCL and provides that the
registrant may fully indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action, suit or
proceeding (whether civil, criminal, administrative or investigative) by reason
of the fact that such person is or was a director or officer of the registrant,
or is or was serving at the request of the Registrant as a director or officer
of another corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise, against expenses (including attorney's fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by such
person in connection with such action, suit or proceeding.

    At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the Certificate. The registrant is not aware of any
threatened litigation or proceeding that may result in a claim for such
indemnification.

ITEM 17. UNDERTAKINGS

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

    The undersigned registrant hereby undertakes that:

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

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

    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 in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of 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 Act and will be governed by the final adjudication of
such issue.
