     This summary highlights some information from this prospectus. It may not
contain all of the information that is important to you. To understand this
offering fully, you should read carefully the entire prospectus, including the
risk factors and the financial statements. Unless otherwise indicated, the
information in this prospectus assumes that the contribution of assets to us by

OVERVIEW OF OUR BUSINESS

     We operate global interactive electronic marketplaces that enable the
trading of financial instruments and other products instantaneously, more
effectively and at lower cost than traditional trading methods. Our marketplaces
are currently used by most of the largest financial institutions and wholesale
market participants to trade in a wide range of global financial instruments,
including government securities denominated in U.S. dollars, Euros, Yen, British
Pounds Sterling, Canadian dollars and currencies of emerging market countries,
as well as securities of U.S. agencies, municipal securities, Eurobonds,
corporate bonds and other global fixed income securities and U.S. Treasury
futures. We operate the largest global electronic marketplace for U.S. Treasury
securities and leading global electronic marketplaces for other fixed income
securities and financial instruments. We also operate a U.S. Treasury futures
exchange marketplace that is known as the CANTOR EXCHANGE (SM), the first fully
electronic futures exchange for the trading of U.S. Treasury futures. Our
current marketplaces process financial instrument transactions of over
$150 billion per day, of which more than $6 billion are wholly-electronic
orders. Our revenues are driven by trading activity and volume in our
marketplaces. We commenced operations in March 1999 as a division of Cantor
Fitzgerald and have not yet made a profit.

     We believe we operate the only electronic marketplaces used for trading in
multiple instruments on a global basis. Over 500 institutions worldwide
participate in our marketplaces, including all of the 25 largest bond trading
firms in the world, as identified by Euromoney Magazine. Most of these
institutions use our proprietary screen displays and/or trading platforms, which
allow us to deliver information and execute transactions instantaneously, on a
secure basis through their computer network security barriers.

OUR INDUSTRY

     Traditional trading methods are relatively slow, expensive and limited. In
both the fixed income and futures markets, trading practices historically have
centered around a method of trading known as open outcry, where trading activity
is focused on a central location, or pit. Market participants in the pit often
have access to better and more timely market information than outsiders. In
order to access the pit, individuals and institutional traders must send their
orders through several layers of middlemen. Transaction costs are high due to
the number of people involved in an open outcry system and execution can be
slow. Program trading is difficult or impossible to implement because of the
current manual nature of these markets, especially programs designed to
automatically and simultaneously execute multiple trades in different, but
related, financial products. Processing, confirming and clearing paper-based
trades are also very time consuming and expensive. Paper and telephone-based
trading produces delayed information and results in compliance programs that are
expensive to manage and can be circumvented. Because of these impediments,
non-electronic trading methods limit trading volume and liquidity.

OUR ELECTRONIC MARKETPLACE SOLUTION

     Our interactive electronic marketplaces are powered by our eSPEED (SM)
system, which employs our private, instantaneous, electronic network and
proprietary transaction processing software. Our eSPEED (SM) system has a
flexible design which allows us to quickly and easily add new financial
instruments in multiple currencies and trading models. It uses our network
distribution system, which we believe is one of the most robust systems in
operation, enabling us to provide access to accurate market information and
instantaneous trade execution. The system is designed to minimize the need for
human intermediaries in the trading process by providing clients with multiple
methods of accessing our marketplaces and executing trades directly, utilizing
INTERACTIVE MATCHING (SM), our proprietary, rules-based trading method that
interactively executes buy and sell orders from multiple market participants.

     The benefits of our eSPEED (SM) system include the following:

     o instantaneous price dissemination and trade execution;

     o lower transaction costs;

     o multiple product program trading;

                                       1
<PAGE>
     o greater accuracy and decreased probability of erroneous trades;

     o integrated compliance and credit risk functions;

     o highly efficient pricing on illiquid securities; and

     o ability to automate back-office functions.

OUR GROWTH STRATEGY

     Our objective is to be the leading provider of interactive electronic
marketplaces worldwide. Our growth strategy to achieve this objective includes:

     o focusing exclusively on developing and operating interactive electronic
       marketplaces;

     o expanding the number of financial and non-financial products in our
       electronic marketplaces;

     o converting clients to fully electronic trading;

     o leveraging existing eSPEED (SM) system connectivity to deploy new
       products and services;

     o enabling online retail broker access to wholesale marketplaces, where
       appropriate, for fixed income securities and other financial products so
       as to allow bonds and other financial instruments to trade online similar
       to stocks;

     o pursuing acquisitions and strategic alliances; and

     o leveraging our eSPEED (SM) system for use in non-financial,
       business-to-business and consumer marketplaces.

OUR HISTORY

     We commenced operations in March 1999 as a division of Cantor Fitzgerald.
Over the past 25 years, Cantor has been a leading global broker-dealer of fixed
income securities. In 1972, Cantor developed the world's first screen-based
brokerage market in U.S. government securities. Since the early 1990s, Cantor
has been developing systems to promote fully electronic marketplaces. Since
1996, Cantor has invested more than $200 million in information technology,
including the development of proprietary electronic transaction processing
software, network distribution systems and related contractual rights, which
culminated in the development of our eSPEED (SM) system.

     Today, Cantor executes in excess of $45 trillion in transaction volume
annually and is a major facilitator of liquidity in numerous financial products
through its offices in the United States, Canada, Europe and Asia. Our
eSPEED (SM) system provides the only way to electronically access Cantor's
marketplaces. Consequently, we believe that clients will be strongly motivated
to use our interactive electronic marketplaces. We share with Cantor a portion
of the transaction-based revenues paid by financial market participants for
trades using our electronic marketplaces. Cantor and most of the largest
financial institutions in the world are currently our primary clients. See
"Relationship with Cantor--Joint Services Agreement."

     Concurrent with this offering, Cantor is contributing to us substantially
all of our assets, including the eSPEED (SM) system. In exchange for these
assets, we are issuing to Cantor common stock that will represent over 98% of
the voting power of our outstanding capital stock after this offering. We
believe our relationship with Cantor is a significant competitive advantage.

    expect to incur in the fourth quarter of fiscal 1999 due to option grants we
    intend to make to Cantor employees exercisable at the initial public

    local tax, which is available to us as a division of Cantor, is not
    available to us as a corporation because of our net operating loss position.
    The determination of shares outstanding and loss per share data reflects the
    effect of the consummation of the formation transactions as discussed in
    "Relationship with Cantor--The Formation Transactions" as if those events
    had taken place at the beginning of the period.

__________________________________RISK FACTORS__________________________________

     The purchase of our Class A common stock involves substantial investment
risks. You should carefully consider the following risk factors, together with
the other information in this prospectus, before purchasing our Class A common
stock. If any of the following risks actually occur, our business, financial
condition or results of operations could be materially adversely affected, the
trading price of our Class A common stock could decline and you may lose all or
part of your investment.

RISKS RELATED TO OUR BUSINESS

BECAUSE WE HAVE A LIMITED OPERATING HISTORY, YOU MAY NOT BE ABLE TO ACCURATELY
EVALUATE eSPEED.

     We are a recently formed company. We have had limited operations to date
and, as a result, we have a limited operating history upon which to evaluate the
merits of investing in our Class A common stock. As an early stage company, we
are subject to risks, expenses and difficulties associated with implementing our
business plan that are not typically encountered by more mature companies. In
particular, our prospects are subject to risks, expenses and uncertainties
encountered by companies in the new and rapidly evolving market for electronic
commerce products and services. These risks include our failure or inability to:

     o provide services to our clients that are reliable and cost-effective;

     o expand our sales structure and marketing programs;

     o increase awareness of our brand or market positioning; and

     o respond to technological developments or service offerings by
       competitors.

We may not be able to implement our business plan successfully, or at all.

BECAUSE WE HAVE A HISTORY OF LOSSES, WE EXPECT TO CONTINUE TO INCUR LOSSES AND
GENERATE NEGATIVE CASH FLOW FROM OPERATIONS FOR THE FORESEEABLE FUTURE.

     Since our inception, we have incurred substantial costs to develop our
technology and infrastructure. As a result, from our inception through September
24, 1999, we have sustained cumulative net losses of $6.6 million or
$6.8 million on a pro forma basis. We expect that we will continue to incur
losses and generate negative cash flow from operations for the foreseeable
future as we continue to develop our systems and infrastructure and expand our
brand recognition and client base through increased marketing efforts.

IF WE DO NOT EXPAND THE USE OF OUR ELECTRONIC SYSTEMS, OR IF OUR AND CANTOR'S
CLIENTS DO NOT UTILIZE OUR MARKETPLACES OR SERVICES, OUR REVENUES AND
PROFITABILITY WILL BE ADVERSELY AFFECTED.

     The use of electronic marketplaces is relatively new. The success of our
business plan depends, in part, on our ability to maintain and expand the
network of brokers, dealers, banks and other financial institutions which will
utilize our interactive electronic marketplaces. We cannot assure you that we
will be able to continue to expand our marketplaces, or that we will be able to
retain the current participants in our marketplaces. None of our agreements with
market participants require them to use our electronic marketplaces.

IF WE ARE UNABLE TO ENTER INTO MARKETING AND STRATEGIC ALLIANCES, WE MAY NOT
GENERATE INCREASED TRADING IN OUR ELECTRONIC MARKETPLACES.

     We expect to enter into strategic alliances with other market participants,
such as retail brokers, exchanges, market makers, clearinghouses and technology
companies, in order to increase client access to and use of our electronic
marketplaces. We cannot assure you that we will be able to enter into these
strategic alliances on terms that are favorable to us, or at all. The success of
these relationships will depend on the amount of increased trading in our
electronic marketplaces by the clients of these strategic alliance partners.
These arrangements may not generate the expected number of new clients or
increased trading volume we are seeking.

                                       5
<PAGE>
     TO INCREASE AWARENESS OF OUR ELECTRONIC MARKETPLACES, WE MAY NEED TO INCUR
SIGNIFICANT MARKETING EXPENSES.

     To successfully execute our business plan, we must build awareness and
understanding of our electronic marketplace services, brand and the adaptability
of our electronic marketplaces for non-financial products. In order to build
this awareness, our marketing efforts must succeed and we must provide
high-quality services. These efforts will require us to incur significant
expenses. We cannot assure you that our marketing efforts will be successful or
that the allocation of funds to these marketing efforts will be the most
effective use of those funds.

IF WE EXPERIENCE COMPUTER SYSTEMS FAILURES OR CAPACITY CONSTRAINTS, OUR ABILITY
TO CONDUCT OUR OPERATIONS COULD BE HARMED.

     We internally support and maintain many of our computer systems and
networks. Our failure to monitor or maintain these systems and networks or, if
necessary, to find a replacement for this technology in a timely and
cost-effective manner, would have a material adverse effect on our ability to
conduct our operations.

     We also rely and expect to rely on third parties for various computer and
communications systems, such as telephone companies, online service providers,
data processors, clearance organizations and software and hardware vendors. Our
systems, or those of our third party providers, may fail or operate slowly,
causing one or more of the following:

     o unanticipated disruptions in service to our clients;

     o slower response times;

     o delays in our clients' trade execution;

     o failed settlement by clients to whom we provide services to facilitate
       settlement operations;

     o decreased client service satisfaction;

     o incomplete or inaccurate accounting, recording or processing of trades;

     o financial losses;

     o litigation or other client claims; and

     o regulatory sanctions.

     We cannot assure you that we will not experience systems failures from
power or telecommunications failure, acts of God or war, human error, natural
disasters, fire, power loss, sabotage, hardware or software malfunctions or
defects, computer viruses, intentional acts of vandalism and similar events. The
assets acquired by us from Cantor in the formation transactions have been
acquired by us "as is." Although Cantor has been using the systems and
technology being transferred to us in its business, there can be no assurance
that such systems and technology are entirely free from defects. To the extent
any defects are discovered, we will not have any recourse against Cantor. Any
system failure that causes an interruption in service or decreases the
responsiveness of our service, including failures caused by client error or
misuse of our systems, could damage our reputation, business and brand name.

IF WE DO NOT EFFECTIVELY MANAGE OUR GROWTH, OUR EXISTING PERSONNEL AND SYSTEMS
MAY BE STRAINED AND OUR BUSINESS MAY NOT OPERATE EFFICIENTLY.

     In order to execute our business plan, we must grow significantly. This
growth will place significant strain on our personnel, management systems and
resources. We expect that the number of our employees, including technical and
management-level employees, will continue to increase for the foreseeable
future. We must continue to improve our operational and financial systems and
managerial controls and procedures, and we will need to continue to expand,
train and manage our technical workforce. We must also maintain close
coordination among our technical, compliance, accounting, finance and marketing
and sales organizations. We cannot assure you that we will manage our growth
effectively, and failure to do so could result in our business operating
inefficiently.

                                       6
<PAGE>
IF WE ARE UNABLE TO KEEP UP WITH RAPID TECHNOLOGICAL CHANGES, WE MAY NOT BE ABLE
TO COMPETE EFFECTIVELY.

     To remain competitive, we must continue to enhance and improve the
responsiveness, functionality, accessibility and features of our proprietary
software, network distribution systems and technologies. The financial services
and e-commerce industries are characterized by rapid technological change,
changes in use and client requirements and preferences, frequent product and
service introductions embodying new technologies and the emergence of new
industry standards and practices that could render our existing proprietary
technology and systems obsolete. Our success will depend, in part, on our
ability to:

     o develop and license leading technologies useful in our business;

     o enhance our existing services;

     o develop new services and technologies that address the increasingly
       sophisticated and varied needs of our existing and prospective clients;
       and

     o respond to technological advances and emerging industry standards and
       practices on a cost-effective and timely basis.

     The development of proprietary electronic trading technology entails
significant technical, financial and business risks. Further, the adoption of
new Internet, networking or telecommunications technologies may require us to
devote substantial resources to modify and adapt our services. We cannot assure
you that we will successfully implement new technologies or adapt our
proprietary technology and transaction-processing systems to client requirements
or emerging industry standards. We cannot assure you that we will be able to
respond in a timely manner to changing market conditions or client requirements.

IF WE WERE TO LOSE THE SERVICES OF MEMBERS OF MANAGEMENT AND EMPLOYEES WHO
POSSESS SPECIALIZED MARKET KNOWLEDGE AND TECHNOLOGY SKILLS, WE MAY NOT BE ABLE
TO MANAGE OUR OPERATIONS EFFECTIVELY OR DEVELOP NEW ELECTRONIC MARKETPLACES.

     Our future success depends, in significant part, on the continued service
of Howard Lutnick, our Chairman and Chief Executive Officer, Frederick Varacchi,
our President and Chief Operating Officer, and our other executive officers and
managers and sales and technical personnel who possess extensive financial
markets knowledge and technology skills. We cannot assure you that we would be
able to find an appropriate replacement for Mr. Lutnick or Mr. Varacchi if the
need should arise. Any loss or interruption of Mr. Lutnick's or Mr. Varacchi's
services could result in our inability to manage our operations effectively
and/or develop new electronic marketplaces. We have not entered into employment
agreements with and we do not have "key person" life insurance policies on any
of our officers or other personnel. All of the members of our senior management
team are also officers, partners or key employees of Cantor. As a result, they
dedicate only a portion of their professional efforts to our business and
operations. We cannot assure you that the time these persons devote to our
business and operations in the future will be adequate and that we will not
experience an adverse effect on our operations due to the demands placed on our
management team by their other professional obligations. We intend to strive to
provide high quality services that will allow us to establish and maintain
long-term relationships with our clients. Our ability to do so will depend, in
large part, upon the individual employees who represent us in our dealings with
clients. The market for qualified programmers, technicians and sales persons is
extremely competitive and has grown more so in recent periods as electronic
commerce has experienced growth. We cannot assure you that we will be successful
in our efforts to recruit and retain the required personnel.


IF CANTOR OR WE ARE UNABLE TO PROTECT THE INTELLECTUAL PROPERTY RIGHTS WE
LICENSE FROM CANTOR OR OWN, OUR ABILITY TO OPERATE ELECTRONIC TRADING
MARKETPLACES MAY BE MATERIALLY ADVERSELY AFFECTED.


     Our business is dependent on proprietary technology and other intellectual
property rights. We license our patented technology from Cantor. The license
arrangement is exclusive, except in the event that (1) we are unwilling to
provide to Cantor any requested services covered by the patents with respect to
a marketplace and Cantor elects not to require us to do so, or we are unable to
provide such services or (2) we do not exercise our right of first refusal to
provide to Cantor electronic brokerage services with respect to a marketplace,
in which case Cantor retains a limited right to use the patents and patent
applications solely in connection with the operation of that marketplace. We
cannot guarantee that the concepts which are the

                                       7
<PAGE>
subject of the patents and patent applications covered by the license from
Cantor are patentable or that issued patents are or will be valid and
enforceable. Where patents are granted in the U.S., we can give no assurance
that equivalent patents will be granted in Europe or elsewhere, as a result of
differences in local laws affecting patentability and validity. Moreover, we
cannot guarantee that Cantor's issued patents are valid and enforceable, or that
third parties competing or intending to compete with us will not infringe any of
these patents. Despite precautions we or Cantor has taken or may take to protect
our intellectual property rights, it is possible that third parties may copy or
otherwise obtain and use our proprietary technology without authorization. It is
also possible that third parties may independently develop technologies similar
to ours. It may be difficult for us to monitor unauthorized use of our
proprietary technology and intellectual property rights. We cannot assure you
that the steps we have taken will prevent misappropriation of our technology or
intellectual property rights.


     We intend to use our eSPEED (SM) service mark for the services described
herein and have applied to register that service mark in a number of
jurisdictions around the world. Although several existing third party
registrations and applications for trademarks consisting of designations similar
to ours in certain European countries have recently come to light, they are for
goods and services that are different from those being offered under our
eSPEED (SM) service mark. Although we are not presently aware of any third party
objections to our use or registration of our eSPEED (SM) service mark in these
countries, and believe we could defend against any third party claims asserted
in these countries, such registrations and applications could potentially affect
the registration, and/or limit our use, of our eSPEED (SM) service mark in these
European countries, thereby requiring us to adopt and use another service mark
for our services in such countries.


IF IT BECOMES NECESSARY TO PROTECT OR DEFEND OUR INTELLECTUAL PROPERTY RIGHTS,
WE MAY HAVE TO RESORT TO COSTLY LITIGATION.

     We may have to resort to litigation to enforce our intellectual property
rights, protect our trade secrets, determine the validity and scope of the
proprietary rights of others, or defend ourselves from claims of infringement,
invalidity or unenforceability. We may incur substantial costs and diversion of
resources as a result of litigation, even if we win. In the event we do not win,
we may have to enter into royalty or licensing agreements. We cannot assure you
that an agreement would be available to us on reasonable terms, if at all.

     One of the patents we license from Cantor and which relates to INTERACTIVE
MATCHING (SM) is currently the subject of litigation involving Liberty Brokerage
Investment Corporation and Liberty Brokerage Inc. This patent is exclusively
licensed to us subject to certain conditions. We will assume responsibility for
defending this suit on behalf of Cantor and its affiliates. If we are not
successful in defending this lawsuit, it could materially adversely affect our
exclusive ability to use the technology covered by the patent and our ability to
compete effectively. We have also agreed to indemnify Cantor with respect to all
costs arising in connection with or relating to this lawsuit, including any
damages or judgments. We cannot assure you that any of the patents owned or
licensed by us will be upheld by a court as valid and/or enforceable. See
"Business--Our Intellectual Property" and "--Legal Proceedings."

IF OUR SOFTWARE LICENSES FROM THIRD PARTIES ARE TERMINATED, OUR ABILITY TO
OPERATE OUR BUSINESS MAY BE MATERIALLY ADVERSELY AFFECTED.

     We license software from third parties, much of which is integral to our
systems and our business. The licenses are terminable if we breach our
obligations under the license agreements. If any of these relationships were
terminated or if any of these third parties were to cease doing business, we may
be forced to spend significant time and money to replace the licensed software.
However, we cannot assure you that the necessary replacements will be available
on reasonable terms, if at all.

IF THE STRENGTH OF OUR DOMAIN NAMES IS DILUTED, THE VALUE OF OUR PROPRIETARY
RIGHTS MAY DECREASE.

     We own many Internet domain names including "www.espeed.com." The
regulation of domain names in the United States and in foreign countries may
change and the strength of our names could be diluted. We may not be able to
prevent third parties from acquiring domain names that infringe or otherwise
decrease the value of our trademarks and other proprietary rights.

                                       8
<PAGE>
IF WE INFRINGE ON PATENT RIGHTS OR COPYRIGHTS OF OTHERS, WE COULD BECOME
INVOLVED IN COSTLY LITIGATION.

     Patents or copyrights of third parties may have an important bearing on our
ability to offer certain of our products and services. We cannot assure you that
we are or will be aware of all patents or copyrights containing claims that may
pose a risk of infringement by our products and services. In addition, patent
applications in the United States are generally confidential until a patent is
issued. As a result, we cannot evaluate the extent to which our products and
services may be covered or asserted to be covered by claims contained in pending
patent applications. In general, if one or more of our products or services were
to infringe patents held by others, we may be required to stop developing or
marketing the products or services, to obtain licenses to develop and market the
services from the holders of the patents or to redesign the products or services
in such a way as to avoid infringing on the patent claims, which could limit the
manner in which we conduct our operations.

     On May 5, 1999, Cantor and The Board of Trade of the City of Chicago, The
New York Mercantile Exchange and The Chicago Mercantile Exchange were sued by
Electronic Trading Systems, Inc. in the United States District Court for the
Northern District of Texas (Dallas Division) for alleged infringement of Wagner
United States patent 4,903,201, entitled "Automated Futures Trade Exchange." The
patent relates to a system and method for implementing an electronic,
computer-automated futures exchange and affects only the CANTOR EXCHANGE (SM).
If the plaintiff is successful in this lawsuit, we may be required to obtain a
license to develop and market one or more of our services, to cease developing
or marketing services or to redesign those services. We cannot assure you that
we would be able to obtain these licenses or that we would be able to obtain
them at commercially reasonable rates or, if unable to obtain licenses, that we
would be able to redesign our services to avoid infringement. Therefore, this
lawsuit could materially adversely affect our ability to offer electronic
trading marketplaces in the future. See "Business--Legal Proceedings."

DUE TO INTENSE COMPETITION IN OUR INDUSTRY, OUR MARKET SHARE AND FINANCIAL
PERFORMANCE COULD SUFFER.

     The electronic trading and Internet-based financial services markets are
highly competitive and many of our competitors are more established and have
greater financial resources than us. We expect that competition will intensify
in the future. Many of our competitors also have greater market presence,
engineering and marketing capabilities and technological and personnel resources
than we do. As a result, as compared to us, our competitors may:

     o develop and expand their network infrastructures and service offerings
       more efficiently or more quickly;

     o adapt more swiftly to new or emerging technologies and changes in client
       requirements;

     o take advantage of acquisitions and other opportunities more effectively;

     o devote greater resources to the marketing and sale of their products and
       services; and

     o more effectively leverage existing relationships with clients and
       strategic partners or exploit more recognized brand names to market and
       sell their services.

Our current and prospective competitors are numerous and include:

     o Interdealer brokerage firms, including Liberty Brokerage Investment
       Corporation and Garban-Intercapital plc.

     o Technology companies and market data and information vendors, including
       Reuters Group plc, Bloomberg L.P. and Bridge Information Systems, Inc.;

     o Securities or futures exchanges or similar entities, including the
       Chicago Board of Trade, the Chicago Mercantile Exchange, the Chicago
       Board of Options Exchange, Eurex, the New York Stock Exchange and the
       Nasdaq National Market;

     o Electronic communications networks, crossing systems and similar entities
       such as Investment Technology Group and Optimark Technologies Inc.; and

     o Consortia such as BrokerTec Global LLC and EuroMTS.

                                       9
<PAGE>
We believe that we may also face competition from large computer software
companies, media and technology companies and some securities brokerage firms
that are currently our clients. In addition, Market Data Corporation, which is
controlled by Iris Cantor and Rodney Fisher, has technology for electronic
trading systems that, if provided to our competitors in the wholesale market,
will be of substantial assistance to them in competing with us. Iris Cantor and
Rod Fisher are limited partners of Cantor. See "Legal Proceedings."

     The number of businesses providing Internet-based financial services is
rapidly growing, and other companies, in addition to those named above, have
entered into or are forming joint ventures or consortia to provide services
similar to those provided by us. Others may acquire the capabilities necessary
to compete with us through acquisitions.

     In the event we extend the application of our INTERACTIVE MATCHING (SM)
technology to conducting or facilitating auctions of consumer goods and services
over the Internet, we expect to compete with both online and traditional sellers
of these products and services. The market for selling products and services
over the Internet is new, rapidly evolving and intensely competitive. Current
and new competitors can launch new sites at a relatively low cost. We expect we
will potentially compete with a variety of companies with respect to each
product or service we offer. We may face competition from e-Bay, priceline.com,
Amazon.com and a number of other large Internet companies that have expertise in
developing online commerce and in facilitating Internet traffic, including
America Online, Microsoft and Yahoo!, which could choose to compete with us
either directly or indirectly through affiliations with other e-commerce
companies. We cannot assure you that we will be able to compete effectively with
such companies.

BECAUSE SOME OF OUR CLIENTS MAY DEVELOP ELECTRONIC TRADING NETWORKS, WE COULD
COMPETE WITH THEM IN ASPECTS OF OUR BUSINESS.

     Consortia owned by some of our clients have announced their intention to
explore the development of electronic trading networks. BrokerTec Global LLC, a
proposed electronic inter-dealer fixed income broker whose members include
Citigroup, Credit Suisse First Boston, Deutsche Bank AG, Goldman Sachs Group,
Lehman Brothers, Merrill Lynch & Co., Dresdner Kleinwort Benson, ABN-AMRO and
Morgan Stanley Dean Witter, has announced its intention to develop or acquire a
facility for electronic trading of U.S. Treasury securities, Euro-denominated
sovereign debt and other fixed income securities and futures-related products.
All of the members of BrokerTec Global LLC are currently clients of Cantor and
ours. Consortia such as BrokerTec Global LLC may compete with us and our
electronic marketplaces in the future. We currently compete with a similar
consortium called EuroMTS in Europe. The members of EuroMTS include the leading
fixed income dealers in European government securities, as well as clients of
Cantor and ours.

IF WE EXPERIENCE LOW TRADING VOLUME IN SECURITIES AND FINANCIAL PRODUCTS, OUR
PROFITABILITY COULD SUFFER.

     We have experienced significant fluctuations in the aggregate trading
volume of securities and financial products being traded in our marketplaces. We
expect that fluctuations in the trading volume of securities and financial
products traded in our marketplaces will occur in the future from time to time
and have a direct impact on our future operating results. This may cause
significant fluctuations in our profitability when the trading volumes are low.

IF ADVERSE ECONOMIC AND POLITICAL CONDITIONS OCCUR, SUBSTANTIAL DECLINES IN THE
U.S. AND GLOBAL FINANCIAL SERVICES MARKETS MAY RESULT AND OUR PROFITABILITY
COULD SUFFER.

     The global financial services business is, by its nature, risky and
volatile and is directly affected by many national and international factors
that are beyond our control. Any one of these factors may cause a substantial
decline in the U.S. and global financial services markets, resulting in reduced
trading volume and turnover. These events could materially adversely affect our
profitability. These factors include:

     o economic and political conditions in the United States and elsewhere in
       the world;

     o concerns over inflation and wavering institutional/consumer confidence
       levels;

     o the availability of cash for investment by mutual funds and other
       wholesale and retail investors;

     o rising interest rates;

     o fluctuating exchange rates;

                                       10
<PAGE>
     o legislative and regulatory changes; and

     o currency values.

     In the past several years, the U.S. financial markets have achieved
historic highs. We do not believe these strong markets can continue
indefinitely. Our revenues and profitability are likely to decline significantly
during periods of stagnant economic conditions or low trading volume in the U.S.
and global financial markets.

IF OUR SYSTEMS PROVE NOT TO BE YEAR 2000 COMPLIANT, WE COULD EXPERIENCE
SIGNIFICANT BUSINESS INTERRUPTIONS.

     With the Year 2000 approaching, many institutions around the world are
reviewing and modifying their computer systems to ensure that they are Year 2000
compliant. The issue, in general terms, is that many existing computer systems
and microprocessors with date functions, including those in non-information
technology equipment and systems, use only two digits to identify a year in the
date field with the assumption that the first two digits of the year are always
"19". Consequently, on January 1, 2000, computers that are not Year 2000
compliant may read the year as 1900. Systems that calculate, compare or sort
using the incorrect date may malfunction.

Because our business is dependent upon the proper functioning of our proprietary
software, technologies and computer systems, a failure of our software,
technologies or systems to be Year 2000 compliant would have a material adverse
effect on us. If not remedied, potential risks include business interruption or
shutdown, financial loss, regulatory actions, reputational harm and legal
liability.

     In addition, we depend upon the proper functioning of third-party computer
and non-information technology systems. These parties include subcontractors,
such as third-party administrators, and vendors, such as software vendors and
providers of telecommunication services, quotation equipment and other
utilities. If the third parties with which we interact have Year 2000 problems
that are not remedied, disruptions may result, which could result in shutdowns
by us and financial loss, regulatory actions, reputational harm and legal
liability. Disruption or suspension of activity in the world's financial markets
is also possible. In addition, uncertainty about the success of remediation
efforts generally may cause many market participants to reduce the level of
their market activities temporarily as they assess the effectiveness of these
efforts during a "phase-in" period beginning in late 1999. This in turn could
result in a general reduction in trading and other market activities. We cannot
predict the impact that such reduction would have on us. Some of our contracts
with our clients represent that our systems will be Year 2000 compliant. For
these and other reasons, we may also be exposed to litigation with our clients
as a result of Year 2000 problems. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Impact of the Year 2000."

BECAUSE WE EXPECT TO CONTINUE TO EXPAND OUR OPERATIONS OUTSIDE NORTH AMERICA, WE
MAY FACE SPECIAL ECONOMIC AND REGULATORY CHALLENGES THAT WE MAY NOT BE ABLE TO
MEET.

     We operate electronic marketplaces throughout Europe and Asia and we plan
to further expand our operations throughout these regions in the future. There
are certain risks inherent in doing business in international markets,
particularly in the regulated brokerage industry. These risks include:

     o less developed automation in exchanges, depositories and national
       clearing systems;

     o unexpected changes in regulatory requirements, tariffs and other trade
       barriers;

     o difficulties in staffing and managing foreign operations;

     o fluctuations in currency exchange rates;

     o reduced protection for intellectual property rights;

     o seasonal reductions in business activity during the summer months; and

     o potentially adverse tax consequences.

     We are required to comply with the laws and regulations of foreign
governmental and regulatory authorities of each country in which we conduct
business. These may include laws, rules and regulations relating to any aspect
of the securities business, including sales methods, trade practices among
broker-

                                       11
<PAGE>
dealers, use and safekeeping of clients' funds and securities, capital
structure, record-keeping, the financing of clients' purchases, broker-dealer
and employee registration requirements and the conduct of directors, officers
and employees. Any failure to develop effective compliance and reporting systems
could result in regulatory penalties in the applicable jurisdiction.

     The growth of the Internet as a means of conducting international business
has also raised many legal issues regarding, among other things, the
circumstances in which countries or other jurisdictions have the right to
regulate Internet services that may be available to their citizens from service
providers located elsewhere. In many cases, there are no laws, regulations,
judicial decisions or governmental interpretations that clearly resolve these
issues. This uncertainty may adversely affect our ability to use the Internet to
expand our international operations, and creates the risk that we could be
subject to disciplinary sanctions or other penalties for failure to comply with
applicable laws or regulations.

IF WE ENTER NEW MARKETS, WE MAY NOT BE ABLE TO SUCCESSFULLY ADAPT OUR TECHNOLOGY
AND MARKETING STRATEGY FOR USE IN THOSE MARKETS.

     We intend to leverage our eSPEED (SM) system and Cantor's relationships to
enter new markets. We cannot assure you that we will be able to successfully
adapt our proprietary software, electronic distribution networks and technology
for use in other markets. Even if we do adapt our software, networks and
technology, we cannot assure you that we will be able to attract clients and
compete successfully in any such new markets. We cannot assure you that our
marketing efforts or our pursuit of any of these opportunities will be
successful. If these efforts are not successful, we could suffer losses while
developing new marketplaces or realize less than expected earnings, which in
turn could result in a decrease in the market value of our Class A common stock.
Furthermore, these efforts may divert management attention or inefficiently
utilize our resources. We intend to create electronic marketplaces for many
financial products by the end of 2000, but there is no guarantee that we will be
able to do so.

IF WE ACQUIRE OTHER COMPANIES, WE MAY NOT BE ABLE TO INTEGRATE THEIR OPERATIONS
EFFECTIVELY.

     Our business strategy contemplates expansion through the acquisition of
exchanges and other companies providing services or having technologies and
operations which are complementary to ours. Acquisitions entail numerous risks,
including:

     o difficulties in the assimilation of acquired operations and products;

     o diversion of management's attention from other business concerns;

     o assumption of unknown material liabilities of acquired companies;

     o amortization of acquired intangible assets, which would reduce future
       reported earnings; and

     o potential loss of clients or key employees of acquired companies.

     We cannot assure you that we will be able to integrate successfully any
operations, personnel, services or products that might be acquired in the
future, and our failure to do so could adversely affect our profitability and
the value of our Class A common stock.

BECAUSE OUR BUSINESS IS SUBJECT TO EXTENSIVE GOVERNMENT AND OTHER REGULATION, WE
MAY FACE RESTRICTIONS WITH RESPECT TO THE WAY WE CONDUCT OUR OPERATIONS.


     The Securities and Exchange Commission, National Association of Securities
Dealers, Inc., Commodity Futures Trading Commission and other agencies
extensively regulate the U.S. securities industry. Our international operations
may be subject to similar regulations in specific jurisdictions. Our U.S.
subsidiaries are required to comply strictly with the rules and regulations of
these agencies. As a matter of public policy, these regulatory bodies are
responsible for safeguarding the integrity of the securities and other financial
markets and protecting the interests of investors in those markets. Most aspects
of our U.S. broker-dealer subsidiaries are highly regulated, including:


     o the way we deal with our clients;

     o our capital requirements;

                                       12
<PAGE>
     o our financial and Securities and Exchange Commission reporting practices;

     o required record keeping and record retention procedures;

     o the licensing of our employees; and

     o the conduct of our directors, officers, employees and affiliates.

     If we fail to comply with any of these laws, rules or regulations, we may
be subject to censure, fines, cease-and-desist orders, suspension of our
business, suspensions of personnel or other sanctions, including revocation of
registration as a broker-dealer. Changes in laws or regulations or in
governmental policies could have a material adverse effect on the conduct of our
business. These agencies have broad powers to investigate and enforce compliance
and punish non-compliance with their rules and regulations. We cannot assure you
that we and/or our directors, officers and employees will be able to fully
comply with, and will not be subject to, claims or actions by these agencies.

     The consumer products and services we anticipate offering through our
electronic marketplaces are likely to be regulated by federal and state
governments. Our ability to provide such services will be affected by these
regulations. The implementation of unfavorable regulations or unfavorable
interpretations of existing regulations by courts or regulatory bodies could
require us to incur significant compliance costs or cause the development of
affected markets to become impractical.

BECAUSE WE ARE SUBJECT TO RISKS ASSOCIATED WITH NET CAPITAL REQUIREMENTS, WE MAY
NOT BE ABLE TO ENGAGE IN OPERATIONS THAT REQUIRE SIGNIFICANT CAPITAL.

     The Securities and Exchange Commission, Commodity Futures Trading
Commission and various other regulatory agencies have stringent rules and
regulations with respect to the maintenance of specific levels of net capital by
broker-dealers. Net capital, which is assets minus liabilities, is the net worth
of a broker or dealer, less deductions for certain types of assets. If a firm
fails to maintain the required net capital, it may be subject to suspension or
revocation of registration by the Securities and Exchange Commission or
Commodity Futures Trading Commission, and suspension or expulsion by these
regulators could ultimately lead to the firm's liquidation. If these net capital
rules are changed or expanded, or if there is an unusually large charge against
net capital, operations that require the intensive use of capital would be
limited. Also, our ability to withdraw capital from broker-dealer subsidiaries
could be restricted, which in turn could limit our ability to pay dividends,
repay debt and redeem or purchase shares of our outstanding stock. A large
operating loss or charge against net capital could adversely affect our ability
to expand or even maintain our present levels of business, which could have a
material adverse effect on our business.

     As of September 24, 1999, if each of our regulated U.S. subsidiaries,
eSpeed Securities, Inc. and eSpeed Government Securities, Inc., had been subject
to the Uniform Net Capital Rule, the minimum net capital we would have had to
maintain would have been $5,000 and $25,000, respectively. At that time, eSpeed
Securities, Inc. and eSpeed Government Securities, Inc. had total net capital of
approximately $90,000, or approximately $85,000 and $65,000, respectively, in
excess of the minimum amount that would have been required. In addition, we may
be subject to net capital requirements in foreign jurisdictions.

BECAUSE WE INTEND TO OFFER ACCESS TO SOME OF OUR MARKETPLACES TO ONLINE RETAIL
BROKERS, WE ARE SUBJECT TO RISKS RELATING TO UNCERTAINTY IN THE REGULATION OF
THE INTERNET.

     There are currently few laws or regulations that specifically regulate
communications or commerce on the Internet. However, laws and regulations may be
adopted in the future that address issues such as user privacy, pricing,
taxation and the characteristics and quality of products and services. For
example, the Telecommunications Act sought to prohibit transmitting various
types of information and content over the Internet. Several telecommunications
companies have petitioned the Federal Communications Commission to regulate
Internet service providers and online service providers in a manner similar to
long distance telephone carriers and to impose access fees on those companies.
This could increase the cost of transmitting data over the Internet. Moreover,
it may take years to determine the extent to which existing laws relating to
issues such as property ownership, libel and personal privacy are applicable to
the Internet. Any new laws or regulations relating to the Internet could
adversely affect our business.

                                       13
<PAGE>
BECAUSE BROKERAGE SERVICES INVOLVE SUBSTANTIAL RISKS OF LIABILITY, WE MAY BECOME
SUBJECT TO RISKS OF LITIGATION.

     Many aspects of our business, and the businesses of our clients, involve
substantial risks of liability. Dissatisfied clients frequently make claims
regarding quality of trade execution, improperly settled trades, mismanagement
or even fraud against their service providers. We and our clients may become
subject to these claims as the result of failures or malfunctions of systems and
services provided by us and may seek recourse against us. We could incur
significant legal expenses defending claims, even those without merit. An
adverse resolution of any lawsuits or claims against us could result in our
obligation to pay substantial damages.

     In addition, we may also become subject to legal proceedings and claims
against Cantor and its affiliates as a result of the formation transactions.
Although Cantor has agreed to indemnify us against claims or liabilities arising
from our assets or operations prior to the formation transactions, we cannot
assure you that such claims or litigation will not harm our business. See
"Relationship with Cantor--Assignment and Assumption Agreement."

IF WE CANNOT DETER EMPLOYEE MISCONDUCT, WE MAY BE HARMED.

     There have been a number of highly publicized cases involving fraud or
other misconduct by employees in the financial services industry in recent
years, and we run the risk that employee misconduct could occur. Misconduct by
employees could include hiding unauthorized or unsuccessful activities from us.
In either case, this type of conduct could result in unknown and unmanaged risks
or losses. Employee misconduct could also involve the improper use of
confidential information, which could result in regulatory sanctions and serious
reputational harm. It is not always possible to deter employee misconduct, and
the precautions we take to prevent and detect this activity may not be effective
in all cases.

BECAUSE OUR BUSINESS IS DEVELOPING, WE CANNOT PREDICT OUR FUTURE CAPITAL NEEDS
OR OUR ABILITY TO SECURE ADDITIONAL FINANCING.

     We anticipate, based on management's experience and current industry
trends, that our existing cash resources, combined with the net proceeds we will
receive from this offering, will be sufficient to meet our anticipated working
capital and capital expenditure requirements for at least the next 12 months.
However, we may need to raise additional funds to:

     o increase the regulatory net capital necessary to support our operations;

     o support more rapid growth in our business;

     o develop new or enhanced services and products;

     o respond to competitive pressures;

     o acquire complementary technologies; and

     o respond to unanticipated requirements.

     We cannot assure you that we will be able to obtain additional financing
when needed on terms that are acceptable, if at all.

RISKS RELATED TO OUR RELATIONSHIP WITH CANTOR

BECAUSE WE DEPEND ON CANTOR'S BUSINESS, EVENTS WHICH IMPACT CANTOR'S OPERATING
RESULTS MAY HAVE A MATERIAL ADVERSE EFFECT ON OUR REVENUES.

     We recognized over 46% of our revenues for the period from March 10, 1999
to September 24, 1999 from transactions in which we received amounts based on
fixed percentages of commissions paid to Cantor. Consequently, any reductions in
the amount of commissions paid to Cantor, including events which impact Cantor's
business or operating results, could have a material adverse effect on our most
significant source of revenues.

                                       14
<PAGE>
     In addition, fees paid to us by Cantor for system services represented
37.7% of our revenues for the period from March 10, 1999 to September 24, 1999.
These fee revenues are remitted to us on a monthly basis.

     We are a general creditor of Cantor to the extent that there are
transaction revenues and system service fees owing to us from Cantor. Events
which negatively impact Cantor's financial position and ability to remit our
share of transaction revenues and system service fees could have a material
adverse effect on our revenues.

CONFLICTS OF INTEREST AND COMPETITION WITH CANTOR MAY ARISE.

     Various conflicts of interest between us and Cantor may arise in the future
in a number of areas relating to our past and ongoing relationships, including
competitive business activities, potential acquisitions of businesses or
properties, the election of new directors, payment of dividends, incurrence of
indebtedness, tax matters, financial commitments, marketing functions, indemnity
arrangements, service arrangements, issuances of our capital stock, sales or
distributions by Cantor of its shares of our common stock and the exercise by
Cantor of control over our management and affairs. Our Joint Services Agreement
with Cantor provides that in some circumstances Cantor can unilaterally
determine the commissions that will be charged to clients for effecting trades
in marketplaces in which we collaborate with Cantor. The determination of the
nature of commissions charged to clients does not affect the allocation of
revenues that Cantor and we share with respect to those transactions. However,
in circumstances in which Cantor determines to charge clients lower commissions,
the amount that we receive in respect of our share of the commissions will
correspondingly be decreased. A majority of our directors and officers following
this offering also serve as directors and/or officers of Cantor. Simultaneous
service as an eSpeed director or officer and service as a director or officer,
or status as a partner, of Cantor could create or appear to create potential
conflicts of interest when such directors, officers and/or partners are faced
with decisions that could have different implications for us and for Cantor.
Mr. Lutnick, our Chairman and Chief Executive Officer, is the sole stockholder
of the managing general partner of Cantor. As a result, Mr. Lutnick controls
Cantor. Upon completion of this offering, Cantor will own all of the outstanding
shares of our Class B common stock, representing approximately 98% of the
combined voting power of all classes of our voting stock. Mr. Lutnick's
simultaneous service as our Chairman and Chief Executive Officer and his control
of Cantor could create or appear to create potential conflicts of interest when
Mr. Lutnick is faced with decisions that could have different implications for
us and for Cantor. See "Relationship with Cantor."

BECAUSE OUR JOINT SERVICES AGREEMENT WITH CANTOR HAS A PERPETUAL TERM AND
CONTAINS NON-COMPETITION PROVISIONS AND RESTRICTIONS ON OUR ABILITY TO PURSUE
STRATEGIC TRANSACTIONS, THIS AGREEMENT MAY BECOME BURDENSOME TO OUR BUSINESS.

     As part of the formation transactions, Cantor will contribute substantially
all of our assets to us. Although Cantor has agreed, subject to certain
conditions, not to compete with us in providing electronic brokerage services,
Cantor is currently engaged in financial instruments and securities transaction
execution and processing operations and other activities which are related to
the electronic trading services we provide. Our Joint Services Agreement
obligates us to perform technology support and other services for Cantor at
cost, whether or not related to our electronic brokerage services, sets forth
the ongoing revenue sharing arrangements between Cantor and us and subjects us
and Cantor to non-competition obligations. The Joint Services Agreement
precludes us from entering into lines of business in which Cantor now or in the
future may engage, or providing or assisting any third party in providing
voice-assisted brokerage services, clearance, settlement and fulfillment
services and related services, except under the limited circumstances described
under "Relationship with Cantor--Joint Services Agreement--Non-competition
Provisions." Although we believe Cantor has no plans to form, acquire or
commence any other operations similar to ours, the Joint Services Agreement
permits Cantor to perform, in limited circumstances, electronic brokerage
operations. In addition, the Joint Services Agreement imposes limitations on our
ability to pursue strategic alliances, joint ventures, partnerships, business
combinations, acquisitions and similar transactions. Because the Joint Services
Agreement has a perpetual term, even in the event of a breach by one of the
parties, and does not provide for modification under its terms, this agreement
may become burdensome for us, may

                                       15
<PAGE>
distract us from focusing on our internal operations, may deter or discourage a
takeover of our company and may limit our ability to expand our operations. See
"Relationship with Cantor."

BECAUSE AGREEMENTS BETWEEN US AND CANTOR ARE NOT THE RESULT OF ARM'S-LENGTH
NEGOTIATIONS, WE MAY RECEIVE LOWER COMMISSIONS FROM, AND PAY HIGHER SERVICE FEES
TO, CANTOR THAN WE WOULD WITH RESPECT TO THIRD PARTY SERVICE PROVIDERS.

     In connection with the formation transactions, we have entered into
Assignment and Assumption Agreements, an Administrative Services Agreement, a
Joint Services Agreement and several other agreements with Cantor relating to
the provision of services to each other and third parties. These agreements are
not the result of arm's-length negotiations because Cantor owns and controls us.
As a result, the prices charged to us or by us for services provided under the
agreements may be higher or lower than prices that may be charged by third
parties and the terms of these agreements may be generally less favorable to us
than those that we could have negotiated with third parties. See "Relationship
with Cantor."

BECAUSE WE DEPEND ON SERVICES AND ACCESS TO OPERATING ASSETS PROVIDED BY THIRD
PARTIES TO CANTOR, WE MAY NOT HAVE RECOURSE AGAINST THOSE THIRD PARTIES.

     Many of the assets and services provided by Cantor under the terms of the
Administrative Services Agreement are leased or provided to Cantor by third
party vendors. As a result, in the event of a dispute between Cantor and a third
party vendor, we could lose access to, or the right to use, as applicable,
office space, personnel, corporate services and operating assets. In such a
case, we would have no recourse with respect to the third party vendor. Our
inability to use these services and operating assets for any reason, including
any termination of the Administrative Services Agreement between us and Cantor
or the agreements between Cantor and third party vendors, could result in
serious interruptions of our operations.

OUR REPUTATION MAY BE AFFECTED BY ACTIONS TAKEN BY CANTOR AND ENTITIES WHICH ARE
RELATED TO CANTOR.

     Initially, Cantor will be our most significant client. Cantor holds direct
and indirect ownership and management interests in numerous other entities which
engage in a broad range of financial services and securities-related activities.
Actions taken by, and events involving, Cantor or these related companies which
are perceived negatively by the securities markets, or the public generally,
could have a material adverse effect on us and could affect the price of our
Class A common stock. In addition, events which negatively affect the financial
condition of Cantor may negatively affect us. These events could cause Cantor to
lose clients that may trade in our marketplaces, could impair Cantor's ability
to perform its obligations under the Joint Services Agreement and other
agreements Cantor enters into with us and could cause Cantor to liquidate
investments, including by selling or otherwise transferring shares of our common
stock.

IF WE BECOME SUBJECT TO LITIGATION AND OTHER LEGAL PROCEEDINGS, WE MAY BE
HARMED.

     From time to time, we and Cantor may become involved in litigation and
other legal proceedings relating to claims arising from our and their operations
in the normal course of business. Cantor is currently subject to a number of
legal proceedings that could affect us. See "Business--Legal Proceedings." We
cannot assure you that these or other litigation or legal proceedings will not
materially affect our ability to conduct our business in the manner that we
expect or otherwise adversely affect us.

RISKS RELATED TO E-COMMERCE AND THE INTERNET

IF ELECTRONIC MARKETPLACES FOR SECURITIES AND FINANCIAL PRODUCTS DO NOT CONTINUE
TO GROW, WE WILL NOT BE ABLE TO ACHIEVE OUR BUSINESS OBJECTIVES.

     The success of our business plan depends on our ability to create
interactive electronic marketplaces in a wide range of securities and financial
products. Historically, securities and commodities markets operated through an
open outcry format in which buyers and sellers traded securities in pits through
verbal communication. These open outcry markets have recently begun to be
supplanted with new systems which match buyers and sellers electronically. The
utilization of our interactive electronic marketplaces depends on

                                       16
<PAGE>
the continued acceptance and utilization of these electronic securities and
commodities markets. We cannot assure you that the growth and acceptance of the
use of electronic markets will continue.

IF E-COMMERCE AND INTERNET USAGE DOES NOT CONTINUE TO GROW, WE WILL NOT BE ABLE
TO ACHIEVE OUR BUSINESS OBJECTIVES.

     As part of our business strategy, we expect to do business with online and
traditional retail brokers. We expect to enable these firms to provide to their
clients access, where appropriate, to trading in fixed income securities and
futures and other wholesale financial products markets through the Internet.

     Our strategic and financial objectives would be adversely impacted if
Internet usage does not continue to grow. Consumer use of the Internet as a
medium of commerce is a recent phenomenon and is subject to a high level of
uncertainty. Internet usage may be inhibited for a number of reasons, including:

     o access costs;

     o inadequate network infrastructure;

     o security concerns;

     o uncertainty of legal, regulatory and tax issues concerning the use of the
       Internet;

     o concerns regarding ease of use, accessibility and reliability;

     o inconsistent quality of service; and

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

     If Internet usage grows, the Internet infrastructure may not be able to
support the demands placed on it, or the Internet's performance and reliability
may decline. Similarly, Web sites have experienced interruptions in their
service as a result of outages and other delays occurring throughout the
Internet network infrastructure. If these outages or delays occur frequently,
use of the Internet as a commercial or business medium could grow more slowly or
decline. Even if Internet usage continues to grow, online trading in the
wholesale securities markets, and in particular the fixed income securities and
futures markets, may not be accepted by retail customers. This could negatively
affect the growth of our business.

OUR NETWORKS AND THOSE OF OUR THIRD PARTY SERVICE PROVIDERS MAY BE VULNERABLE TO
SECURITY RISKS, WHICH COULD MAKE OUR CLIENTS HESITANT TO USE OUR ELECTRONIC
MARKETPLACES.

     We expect the secure transmission of confidential information over public
networks to be a critical element of our operations. Our networks and those of
our third party service providers, including Cantor and associated clearing
corporations, and our clients may be vulnerable to unauthorized access, computer
viruses and other security problems. Persons who circumvent security measures
could wrongfully use our information or cause interruptions or malfunctions in
our operations, which could make our clients hesitant to use our electronic
marketplaces. We may be required to expend significant resources to protect
against the threat of security breaches or to alleviate problems, including
reputational harm and litigation, caused by any breaches. Although we intend to
continue to implement industry-standard security measures, we cannot assure you
that those measures will be sufficient.

RISKS RELATED TO OUR CAPITAL STRUCTURE

BECAUSE THE VOTING CONTROL OF OUR COMMON STOCK WILL BE CONCENTRATED AMONG THE
HOLDERS OF OUR CLASS B COMMON STOCK, THE MARKET PRICE OF OUR CLASS A COMMON
STOCK MAY BE ADVERSELY AFFECTED BY DISPARATE VOTING RIGHTS.

     After this offering, Cantor will beneficially own all of our outstanding
Class B common stock, representing approximately 98% of the combined voting
power of all classes of our voting stock. As long as Cantor beneficially owns a
majority of the combined voting power of our common stock, it will have the
ability, without the consent of the public stockholders, to elect all of the
members of our board of directors and to control our management and affairs. In
addition, it will be able to determine the outcome of matters submitted to a
vote of our stockholders for approval and will be able to cause or prevent a
change in control

                                       17
<PAGE>
of our company. In certain circumstances, the Class B common stock issued to
Cantor upon consummation of the formation transactions may be transferred
without conversion to Class A common stock.

     The holders of our Class A common stock and Class B common stock have
substantially identical rights, except that holders of our Class A common stock
are entitled to one vote per share, while holders of our Class B common stock
are entitled to 10 votes per share on all matters to be voted on by stockholders
in general. This differential in the voting rights and our ability to issue
additional Class B common stock could adversely affect the market price of our
Class A common stock.

DELAWARE LAW AND OUR CHARTER MAY MAKE A TAKEOVER OF OUR COMPANY MORE DIFFICULT.

     Provisions of Delaware law, such as its business combination statute, may
have the effect of delaying, deferring or preventing a change in control of our
company. In addition, our Amended and Restated Certificate of Incorporation
authorizes the issuance of preferred stock, which our board of directors can
create and issue without prior stockholder approval and with rights senior to
those of our common stock, as well as additional shares of our Class B common
stock. Our Amended and Restated Certificate of Incorporation and our Amended and
Restated By-Laws include provisions which restrict the ability of our
stockholders to take action by written consent and provide for advance notice
for stockholder proposals and director nominations. These provisions may have
the effect of delaying or preventing changes of control or management of our
company, even if such transactions would have significant benefits to our
stockholders. As a result, these provisions could limit the price some investors
might be willing to pay in the future for shares of our Class A common stock.

DELAWARE LAW MAY PROTECT DECISIONS OF OUR BOARD OF DIRECTORS THAT HAVE A
DIFFERENT EFFECT ON HOLDERS OF OUR CLASS A AND CLASS B COMMON STOCK.

     You may not be able to challenge decisions that have an adverse effect upon
holders of the Class A common stock if our board of directors acts in a
disinterested, informed manner with respect to these decisions, in good faith
and in the belief that it is acting in the best interests of our stockholders.
Delaware law generally provides that a board of directors owes an equal duty to
all stockholders, regardless of class or series, and does not have separate or
additional duties to either group of stockholders, subject to applicable
provisions set forth in a company's charter.

BECAUSE WE ARE A HOLDING COMPANY, WE WILL DEPEND ON OUR SUBSIDIARIES TO GENERATE
REVENUES AND DISTRIBUTE CASH TO US.

     We are a holding company. Our sole assets are our equity interests in our
subsidiaries. We have no independent means of generating revenues. We will incur
income taxes on revenues that we generate. We intend to cause our subsidiaries
to distribute cash to us in amounts sufficient to cover our tax liabilities, if
any. Our subsidiaries' ability to distribute cash to us will be subject to legal
restrictions, including the net capital rules and the requirements that they
have surplus capital or earnings available for distribution. We cannot assure
you that our subsidiaries will be able to provide us with the funds necessary to
satisfy our obligations or conduct our operations as contemplated by our
business strategy.

RISKS RELATED TO THIS OFFERING

THERE HAS NOT BEEN ANY PRIOR PUBLIC MARKET FOR OUR CLASS A COMMON STOCK, AND WE
CANNOT ASSURE YOU THAT AN ACTIVE TRADING MARKET WILL DEVELOP OR BE SUSTAINED.

     Prior to this offering, there has been no public market for the Class A
common stock and we cannot assure you that an active trading market will develop
or be sustained. The initial public offering price of our Class A common stock
will be determined through negotiation between us and the representatives of the
underwriters and may not be indicative of the market price for our Class A
common stock after this offering.

                                       18
<PAGE>
THE MARKET PRICE OF OUR CLASS A COMMON STOCK MAY FLUCTUATE WIDELY AND TRADE AT
PRICES BELOW THE INITIAL PUBLIC OFFERING PRICE.

     The price of our Class A common stock after this offering may fluctuate
widely, depending upon many factors, including our perceived prospects, and the
prospects of the financial industries in general, differences between our actual
financial and operating results and those expected by investors and analysts,
changes in analysts' recommendations or projections, changes in general
valuations for Internet and e-commerce-related companies, changes in general
economic or market conditions and broad market fluctuations. As a result, our
Class A common stock may trade at prices significantly below the initial public
offering price.

MANAGEMENT WILL HAVE DISCRETION OVER THE USE OF PROCEEDS WE RECEIVE FROM THIS
OFFERING AND MAY NOT USE THE FUNDS IN A MANNER THAT YOU WOULD APPROVE.

     We intend to use the majority of the net proceeds we receive from this
offering for technological and product development and improvements in existing
and new marketplaces, hiring technology and other personnel to develop new
products, sales, marketing and advertising initiatives and working capital and
general corporate purposes, including possible acquisitions. Pending application
of these uses, we intend to use the net proceeds to purchase short-term
marketable securities. Our management will have broad discretion with respect to
the use of these funds and the determination of the timing of expenditures. We
cannot assure you that management will use these funds in a manner that you
would approve or that the allocations will be in the best interests of our
stockholders.

YOUR SHARE OWNERSHIP IN eSPEED WILL BE IMMEDIATELY AND SUBSTANTIALLY DILUTED.

     Purchasers of our Class A common stock in this offering will experience
immediate and substantial dilution in net tangible book value of $16.05 per
share, based on an assumed initial public offering price of $18.00 per share.

FUTURE SALES OF OUR SHARES COULD ADVERSELY AFFECT THE MARKET PRICE OF OUR
CLASS A COMMON STOCK.

     If our existing stockholders sell a large number of shares, or if we issue
a large number of shares of our common stock in connection with future
acquisitions, strategic alliances or otherwise, the market price of our Class A
common stock could decline significantly. Moreover, the perception in the public
market that these stockholders might sell shares of Class A common stock could
depress the market price of our Class A common stock.

     Although we and our directors, executive officers and holders of common
stock and securities convertible into or exercisable or exchangeable for common
stock issued prior to this offering or in connection with the consummation of
the formation transactions have agreed pursuant to certain "lock-up" agreements
with the underwriters that we and they will not offer, sell, contract to sell,
pledge, grant any option to sell, or otherwise dispose of, directly or
indirectly, any shares of common stock or securities convertible into or
exercisable or exchangeable for common stock, subject to certain exceptions, for
a period of 180 days after the date of this prospectus without the prior written
consent of Warburg Dillon Read LLC, we and these persons may be released of this
obligation by Warburg Dillon Read LLC in its sole discretion in whole or in part
at any time with or without notice.

     We plan to register an additional 5,000,000 shares of our Class A common
stock under the Securities Act within 90 days after the closing of this offering
for use by us as consideration for future acquisitions. Upon such registration,
these shares generally will be freely tradable after issuance, unless the resale
thereof is contractually restricted or unless the holders thereof are subject to
the restrictions on resale provided in Rule 145 under the Securities Act. In any
event, any registered shares so issued will be subject to contractual
restrictions and, thus, will not be freely tradable during the 180-day period
after the date of this prospectus.

     After this offering, we intend to initially register 20%, or approximately
10,000,000 shares of Class A common stock, of the total outstanding shares of
our common stock, which are reserved for issuance upon exercise of options
granted under our stock option plan. If we increase our total outstanding shares
of common stock, we will register additional shares of Class A common stock so
that the stock available for issuance under our stock option plan will be
registered. Once we register these shares, they can be sold in the

                                       19

public market upon issuance, subject to restrictions under the securities laws
applicable to resales by affiliates. We also plan to register the shares of
Class A common stock issuable under our stock purchase plan. See "Shares
Eligible for Future Sale."

___________________________FORWARD-LOOKING STATEMENTS___________________________

     This prospectus contains forward-looking statements that involve risks and
uncertainties. Discussions containing such forward-looking statements are found
in the material set forth under "Prospectus Summary," "Risk Factors,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business," as well as in this prospectus generally. When used
in this prospectus, the words "anticipate," "believe," "expect," "estimate" and
similar expressions are generally intended to identify forward-looking
statements. Our actual results could differ materially from those anticipated in
the forward-looking statements as a result of certain factors, including the
risks described in "Risk Factors" and elsewhere in this prospectus.

_________________________________USE OF PROCEEDS________________________________

     If we sell the Class A common stock offered by us through this prospectus
at a public offering price of $18.00 per share, we estimate that we will receive
net proceeds (after deducting underwriting discounts and commissions and
estimated offering expenses) of $98,530,000 ($115,360,000 if the underwriters
exercise their over-allotment option in full).

     We intend to use the net proceeds of this offering as follows:

     o approximately $25 million will be for investment in hardware and software
       for entry into new product segments, expansion of our current markets and
       an increase in communication links to our clients;

     o approximately $25 million will be for hiring of technology and other
       professionals to develop new markets in both financial and non-financial
       sectors; and

     o approximately $25 million will be for marketing to current and new
       institutional clients and to promote general awareness and acceptance of
       the retail trading of fixed income securities and other financial
       instruments.

     We intend to use the remainder of the net proceeds for working capital and
general corporate purposes, including possible acquisitions. We do not currently
have any agreements with respect to any such acquisitions. The occurrence of
unforeseen events, opportunities or changed business conditions, however, could
cause us to use the proceeds of this offering in a manner other than as
described in this prospectus. Pending these uses, we intend to invest the net
proceeds we receive in short-term marketable securities. We believe that the net
proceeds of this offering and cash flows from operations will be sufficient to
fund our working capital needs and capital expenditure requirements for the
foreseeable future. We will not receive any of the proceeds from the sale of
shares by the selling stockholder of our Class A common stock.

_________________________________DIVIDEND POLICY________________________________

     We intend to retain our future earnings, if any, to help finance the growth
and development of our business. We have never paid a cash dividend and we do
not expect to pay any cash dividends on our common stock in the foreseeable
future.

     In the event we decide to declare dividends on our common stock in the
future, such declaration will be subject to the discretion of our board of
directors. Our board of directors may take into account such matters as general
business conditions, our financial results, capital requirements, contractual,
legal and regulatory restrictions on the payment of dividends by us to our
stockholders or by our subsidiaries to us and any such other factors as our
board of directors may deem relevant.

____________________________________DILUTION____________________________________

     The net tangible book value of our common stock, including our Class B
common stock, at September 24, 1999, before adjustment for this offering, was
$(958,542), or $(0.02) per share. Net tangible book value per share represents
the amount of total tangible assets less total liabilities, divided by the
number of shares of common stock outstanding. After giving effect to the sale of
the 6,000,000 shares of Class A common stock by eSpeed in this offering, at an
assumed initial public offering price of $18.00 per share (the midpoint of the
range set forth on the cover page of this prospectus), our net tangible book
value at September 24, 1999 would have been $97,571,458, or $1.95 per share,
calculated as follows:

</TABLE>

     Assuming the underwriters' over-allotment option is exercised in full, the
net tangible book value at September 24, 1999 would have been $114,401,458, or
$2.24 per share, the immediate increase in net tangible book value of shares
owned by existing stockholders would have been $2.26 per share, and the
immediate dilution to purchasers of shares of Class A common stock in this
offering would have been $15.76 per share.

     The following table summarizes at September 24, 1999, after giving effect
to the sale of the 6,000,000 shares of Class A common stock by eSpeed in this
offering at an assumed initial public offering of $18.00 per share (the midpoint
of the range set forth on the cover page of this prospectus), and the
consummation of the formation transactions as discussed in "Relationship with
Cantor--The Formation Transactions," (1) the number and percentage of shares of
common stock issued by us, (2) the total cash and non-cash consideration paid
for our common stock, and (3) the average price per share of common stock paid

     The calculations in the tables set forth above do not reflect (1) an
aggregate of 10,000,000 shares of Class A common stock reserved for issuance
under our stock option plan, including 7,500,000 shares of Class A common stock
subject to options to be granted in connection with this offering and
(2) 127,500 shares of Class A common stock reserved for issuance upon exercise
of warrants we expect to grant upon completion of this offering. See
"Management--1999 Long-Term Incentive Plan" and "Underwriting."

- ------------------
(1) Sales by the selling stockholder in this offering will reduce the number of
    shares held by existing stockholders to 41,500,000 shares, or approximately
    83% of the total shares of common stock outstanding, and, together with this
    offering, will result in 8,500,000 shares being held by new investors, or
    17% of the total shares of common stock outstanding after this offering.

    is available to us as a division of Cantor, is not available to us as a
    corporation because of our net operating loss position. The determination of
    shares outstanding and loss per share data reflects the effect of the
    consummation of the formation transactions as discussed in "Relationship
    with Cantor--The Formation Transactions" as if those events had taken place
    at the beginning of the period.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
__________________FINANCIAL CONDITION AND RESULTS OF OPERATIONS_________________

     The following discussion contains forward-looking statements that involve
risks and uncertainties. Our actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain factors,
including those set forth in "Risk Factors" and elsewhere in this prospectus.
The following discussion is qualified in its entirety by, and should be read in
conjunction with, the more detailed information and our financial statements and
the notes thereto appearing elsewhere in this prospectus.

OVERVIEW

     eSpeed was incorporated on June 3, 1999 as a Delaware corporation and,
following this offering, will operate primarily through its wholly-owned
subsidiaries, eSpeed Securities, Inc., eSpeed Government Securities, Inc.,
eSpeed Markets, Inc. and eSpeed Securities International Limited. Prior to this
offering, eSpeed was a wholly-owned subsidiary of, and it conducted its
operations as a division of, Cantor Fitzgerald Securities, which in turn is a
99.5%-owned subsidiary of Cantor Fitzgerald, L.P. eSpeed commenced operations as
a division of Cantor on March 10, 1999, the date the first fully electronic
transaction using the eSPEED (SM) system was executed. Cantor has been
developing systems to promote fully electronic marketplaces since the early
1990's. Since January 1996, Cantor has used the eSPEED (SM) system internally to
conduct electronic trading.

     Concurrent with this offering, Cantor is contributing to us, and we are
acquiring from Cantor, substantially all of our assets. These assets primarily
consist of proprietary software, network distribution systems, technologies and
other related contractual rights that comprise our eSPEED (SM) system. See
"Relationship with Cantor--The Formation Transactions."

     Since commencing operations, we have relied on Cantor to provide financing
and cash flow for our operations and we have incurred a net loss over this
period. This loss primarily results from expenditures on our technology and
infrastructure incurred in building our revenue base. Our focus for the
immediate future is to enable fully electronic trading of additional financial
products and to aggressively seek to migrate Cantor's existing clients to our
eSPEED (SM) system.

     As of September 24, 1999, we had an accumulated net loss of $6,613,841. We
expect that we will continue to incur losses and generate negative cash flow
from operations for the foreseeable future as we continue to develop our systems
and infrastructure and expand our brand recognition and client base through
increased marketing efforts. In light of the rapidly changing nature of our
business and our limited operating history, we believe that period-to-period
comparisons of our operating results will not necessarily be meaningful and
should not be relied upon as an indication of future performance.

     If we were subject to income tax as a corporation, as of September 24,
1999, the pro forma net loss would have been $6,785,648. This pro forma
adjustment reflects the tax benefit for state and local tax, which is available
to us as a division of Cantor, but is not available to us as a corporation.
Since we paid no previous taxes to state and local governments due to our net
operating loss position, we would not receive a refund.

     In September 1999, our board of directors changed our fiscal year from the
last Friday of March to December 31.

REVENUES

  Transaction Revenues

     We operate interactive electronic marketplaces. We have entered into a
Joint Services Agreement with Cantor under which we and Cantor have agreed to
collaborate to provide brokerage and related services to clients in multiple
electronic markets for transactions in securities and other financial products.
In addition, we may, in our discretion, collaborate on operating markets for
non-financial products. Under this agreement, we will own and operate the
electronic trading systems and will be responsible for providing electronic
brokerage services, and Cantor will provide voice-assisted brokerage services,
clearance and settlement services and related services, such as credit and risk
management services, oversight of client suitability and regulatory compliance,
sales positioning of products and other services customary to brokerage
operations. While we have no obligation under the Joint Services Agreement to do
so, we intend to use approximately $25 million of the proceeds received by us
from this offering for sales, marketing and advertising expenses related to our
existing marketplaces and the development of new marketplaces. Under this
agreement, we and Cantor have agreed to share revenues derived from transactions
effected in the marketplaces in which we collaborate and other specified
markets.

  If the transactions:

     o are effected in a marketplace in which we collaborate with Cantor, are
       fully electronic transactions and relate to financial products, such as
       fixed income securities, futures contracts, derivatives and commodities,
       that are not traded on the CANTOR EXCHANGE (SM), or products that are
       traded on the CANTOR EXCHANGE (SM), then we will receive the aggregate
       transaction revenues and pay to Cantor service fees equal to 35% and 20%
       of the transaction revenues, respectively.

     o are effected in a marketplace in which we collaborate with Cantor,
       involve voice-assisted brokerage services that Cantor provides and the
       transactions relate to (1) financial products that are not traded on the
       CANTOR EXCHANGE (SM), or (2) products that are traded on the CANTOR
       EXCHANGE (SM), then, in the case

                                       25
<PAGE>
       of a transaction described in (1), Cantor will receive the aggregate
       transaction revenues and pay to us a service fee equal to 7% of the
       transaction revenues, and, in the case of a transaction described in (2),
       we will receive the aggregate transaction revenues and pay to Cantor a
       service fee equal to 55% of the transaction revenues.

     o are effected in a marketplace in which we do not collaborate with Cantor,
       but in which we do provide electronic brokerage services, and (1) the
       transaction relates to a financial product, then we will receive the
       aggregate transaction revenues and pay to Cantor a service fee equal to
       20% of the transaction and data revenues paid to or received by us or (2)
       the transaction relates to a non-financial product, then we will receive
       all of the transaction revenues.

     o are not effected through an electronic marketplace, but are
       electronically assisted, such as screen-assisted open outcry
       transactions, then Cantor receives the aggregate transaction revenues and
       pays to us a service fee equal to 2.5% of the transaction revenues.

     We are pursuing an aggressive strategy to convert most of Cantor's
financial marketplace products to our eSPEED (SM) system and, with the
assistance of Cantor, to continue to create new markets and aggressively convert
new clients to our eSPEED (SM) system. Other than Cantor, no client of ours
accounts for more than 10% of our transaction revenues.

     The process of converting these marketplaces includes modifying existing
Cantor trading systems to allow for transactions to be entered directly from a
client location, signing an agreement with the client, installing the hardware
and software at the client location and establishing communication lines between
us and the client.

  System Services Fees


     We have agreed to provide to Cantor technology support services at cost,
including (1) systems administration, (2) internal network support, (3) support
and procurement for desktops of end-user equipment, (4) operations and disaster
recovery services, (5) voice and data communications, (6) support and
development of systems for clearance and settlement services, (7) systems
support for Cantor brokers, (8) electronic applications systems and network
support for the unrelated dealer businesses with respect to which we will not
collaborate with Cantor and (9) provision and/or implementation of existing
electronic applications systems, including improvements and upgrades thereto,
and use of the related intellectual property rights, having potential
application in a gaming business. These revenues are received from Cantor and
represented 37.7% of revenues for the period from March 10, 1999 to September
24, 1999.


EXPENSES

  Compensation and employee benefits

     We currently employ approximately 330 professionals, substantially all of
whom are full time employees who are located predominantly in New York and
London. Compensation costs include salary, bonus accruals, payroll taxes and
costs of employer-provided medical benefits for our employees. We anticipate
granting approximately 300,000 stock options to certain employees of Cantor at
an exercise price per share equal to the initial public offering price. This
will result in an estimated, one time non-cash charge to eSpeed of approximately
$4 million. We intend to hire additional technical, sales and marketing, product
development and administrative personnel from within and outside Cantor in order
to expand our business. As a result, we anticipate that compensation expense may
increase significantly in subsequent periods.

  Occupancy and equipment

     Occupancy and equipment costs include depreciation on computer and
communications equipment and amortization of software owned by us, lease costs
of other fixed assets leased by us from Cantor and a charge for premises costs
from Cantor. Fixed assets are reflected as if they were contributed to us by
Cantor in a non-cash transaction effective March 10, 1999 at their then current
net book value (cost less accumulated depreciation) of $7,370,560. Cantor leases
from third parties under operating lease arrangements certain computer related
fixed assets that we have the right to use at rates intended to equal costs
incurred by

                                       26
<PAGE>
Cantor. Our equipment expenses should increase as we continue to invest in
technology and related equipment.

  Professional and consulting fees

     Professional and consulting fees consist primarily of consultant costs paid
to outside computer professionals who perform specialized enhancement activities
for us. We currently have approximately 20 contracted consultants and additional
outside service providers working under short-term contracts costing
approximately $500,000 per month in the aggregate. The costs of professional
legal counsel engaged to defend the patents used in our business amounted to
approximately $344,000 for the period from March 10, 1999 to September 24, 1999.
Our professional and consulting expenses will likely increase over the
foreseeable future.

  Communications and client networks

     Communications costs include the costs of local and wide area network
infrastructure, the cost of establishing the client network linking clients to
us, data and telephone lines, data and telephone usage and other related costs.
We expect such costs to increase as we continue to expand into new marketplaces
and geographic locations and establish additional communication links with
clients. However, certain communications costs are decreasing globally due to
increased competition in the communications industry. This may or may not result
in a decrease in our communications costs.

  Transaction services fees

     Under the Joint Services Agreement, we are required to pay to Cantor a
transaction services fee of 20% or 35%, depending on the type of transaction, of
commissions paid by clients related to fully electronic transactions. As we
continue to sign up new clients, in conjunction with Cantor, and the volume of
business processed in the fully electronic brokerage channel increases, this
expense and associated revenues will also increase. See "Relationship with
Cantor--Joint Services Agreement."

  Administrative fees

     An Administrative Services Agreement with Cantor has been entered into
under which Cantor has agreed to provide various administrative services to us,
including, but not limited to, accounting, tax, legal and human resources, and
we have agreed to provide sales and marketing services at cost to Cantor. We are
required to reimburse Cantor for its costs of providing these services plus an
allocation of overhead. We have provided for the cost of such services in our
financial statements under the terms set forth in the Administrative Services
Agreement as if it was effective for the period from March 10, 1999 to
September 24, 1999. This amount averaged approximately $150,000 per month for
the period from March 10, 1999 to September 24, 1999. As we expand our business,
the services provided by Cantor, and accordingly the expense, will likely also
increase. As circumstances warrant, we will consider adding employees to take
over these services from Cantor. See "Relationship with Cantor--Administrative
Services Agreement."

                                       27
<PAGE>
  Other expenses

     Other expenses consist primarily of travel, promotional and entertainment
expenditures. These expenses will also continue to increase over the foreseeable
future as we seek to expand our business.

     As of March 26, 1999, June 25, 1999 and September 24, 1999, three, 10 and
45 of our clients, respectively, had fully electronic trading capabilities
through us. As of November 15, 102 of our clients had fully electronic
capabilities through us.

LIQUIDITY AND CAPITAL RESOURCES

     During the period from March 10, 1999 to September 24, 1999, we generated
cash from operations of $3,602,564. This was attributable to offsetting the
costs of funding our net loss of $6,613,841 through amounts payable to Cantor
and accruals for compensation and benefits.

     Our cash flow is comprised of transaction revenues and system services fees
from Cantor, and charges from Cantor of various fees, occupancy costs and other
expenses paid by Cantor on our behalf. In acting in its capacity as a broker,
Cantor will process and settle the transaction and, as such, collect/pay the
funds necessary to clear the transaction with the counterparty. In doing so,
Cantor will receive our commission on the transaction, and in accordance with
the Administrative Services Agreement and the Joint Services Agreement, will
remit the gross amount of the commission owed to us. Under the Administrative
Services Agreement and the Joint Services Agreement, any net receivable or
payable will be settled monthly at the discretion of the parties.

     Our ability to withdraw capital from our regulated broker-dealer
subsidiaries could be restricted, which in turn could limit our ability to pay
dividends, repay debt and redeem or purchase shares of our outstanding stock.

     We believe that cash flows from operations and the net proceeds of this
offering will be sufficient to fund our working capital needs and capital
expenditure requirements for the forseeable future. In the event we consummate
any acquisitions, we may need to incur indebtedness or raise public or private
debt or issue

                                       28
<PAGE>
equity to help finance any such acquisitions. There is no assurance that any
such financing will be obtainable on acceptable terms or at all.

IMPACT OF THE YEAR 2000

     The year 2000 computer problem refers to the potential for system and
processing failures of date related data as a result of computer controlled
systems using two digits rather than four to define the applicable year. For
example, computer programs that have time sensitive software may recognize a
date represented as 00 as the year 1900 rather than the year 2000. This could
result in a system failure or miscalculations causing disruptions in operations,
including, among other things, a temporary inability to process transactions,
send transmissions to clearing agents or engage in similar normal business
activities.

     Our year 2000 plan is part of normal day-to-day Information Technology
department efforts, using existing staff. Over 150 Information Technology
employees, including 20 systems managers from eSpeed and other managers from
Cantor, are responsible for addressing potential year 2000 problems, including
identification, assessment, repair and testing of their respective applications
and systems. Year 2000 managers meet monthly to discuss critical paths, modify
priorities to adjust to unforeseen problems and review the master year 2000
project plan.

     We and Cantor believe we have thoroughly tested all mission critical
systems using the testing procedures and key dates that have been established
for the Wall Street testing program conducted by the Securities Industry
Association. In order to ensure compliance, each system must complete four
levels of testing:

     (1) unit testing to determine whether each individual application's
         functionality remained intact;

     (2) integration testing to validate two or more compliant systems perform
         as expected;

     (3) point-to-point testing to validate that clients still have expected
         functionality; and

     (4) industry-wide testing to show functionality between other participants.
         In addition, all applications have participated in individual
         point-to-point testing as required.

     We and Cantor have completed our internal information technology and
non-information technology assessment and testing, and we believe that our and
Cantor's internal software and hardware systems will function properly with
respect to dates in the year 2000 and thereafter. Our and Cantor's contingency
plan in the event of any system failure due to the year 2000 problem will be to
manually process trades.

  Cost

     Based on our and Cantor's assessment to date, our and Cantor's combined
costs associated with upgrades to hardware and software, testing and remediating
our systems are approximately $9.0 million. The majority of this was incurred
prior to our commencement of operations. We anticipate incurring an additional
$150,000 to complete our year 2000 project activities.

  Risks

     Because we and Cantor are dependent, to a very substantial degree, upon the
proper functioning of computer systems, the failure of any computer system to be
year 2000 compliant could materially adversely affect us. Failure of this kind
could, for example, cause execution of trades to be inefficient or even to fail,
lead to incomplete or inaccurate accounting, recording or processing of trades
or result in generation of erroneous results or adversely affect our ability to
develop new products. If not remedied, potential risks include business
interruption or shutdown, financial loss, regulatory actions, reputational harm
and legal liability.

MARKET RISK ISSUES

     In the normal course of business, we maintain no inventory of securities
and, as such, we are not subject to market risk on investments.

OVERVIEW OF OUR BUSINESS

     We operate global interactive electronic marketplaces designed to enable
market participants to trade financial instruments and other products
instantaneously, more effectively and at lower cost than traditional trading
methods. Our marketplaces are currently used by most of the largest financial
institutions and wholesale market participants to trade in a wide range of
global fixed income securities, futures, options and other financial
instruments. These financial instruments include government securities
denominated in U.S. dollars, Euros, Yen, British Pounds Sterling, Canadian
dollars and currencies of emerging market countries, as well as securities of
U.S. agencies, municipal securities, Eurobonds, corporate bonds and other global
fixed income securities and U.S. Treasury futures. We operate the largest global
electronic marketplace for U.S. Treasury securities and leading global
electronic marketplaces for the other fixed income securities and financial
instruments, most of which have been converted or are being converted to our
eSPEED (SM) electronic trading platform. Our current marketplaces process
financial instrument transactions of over $150 billion per day, of which more
than $6 billion are wholly-electronic orders not involving any person as an
intermediary. Our revenues are driven by trading activity and volumes in our
marketplaces.

     We believe we operate the only electronic marketplaces used for trading in
multiple securities and financial and non-financial instruments on a global
basis. We also operate a U.S. Treasury futures exchange marketplace that is
known as the CANTOR EXCHANGE (SM). It is the first fully electronic futures
exchange for the trading of U.S. Treasury futures and, we expect, will serve as
our platform for the electronic trading of a broad range of futures contracts
globally. Over 500 institutions worldwide participate in our marketplaces,
including all of the 25 largest bond trading firms in the world, as identified
by Euromoney Magazine. Most of these institutions use our proprietary
eSPEED (SM) screen displays and/or trading platforms, which allow us to deliver
information and execute transactions instantaneously through their computer
security barriers that permit or exclude entry into their internal network. We
have devoted significant resources to developing client arrangements, providing
point-to-point communication links, and creating proprietary software to
establish connectivity through these security barriers in order to deliver data
and execute transactions for our clients on a secure basis.

     Our interactive electronic marketplaces are powered by our eSPEED (SM)
system, which employs our private, instantaneous, electronic network and
proprietary transaction processing software. Our system supports execution of
trades internally by Cantor and enables fully electronic trading by our clients.
We believe these components form one of the most robust trading systems in the
world. The network is distributed and permits market participants to view
information and execute trades in a fraction of a second from locations around
the globe. Our trades are processed using INTERACTIVE MATCHING (SM), our
proprietary, rules-based trading method that interactively executes the orders
of multiple market participants. INTERACTIVE MATCHING (SM) encourages trading by
giving the successful active participant in a transaction a time-based right of
first refusal on the next sale/purchase. Some of the rules employed in
INTERACTIVE MATCHING (SM) provide participants that expose their orders to the
market with priority in the interactive auction process. Because of its unique
trading rules, we believe that INTERACTIVE MATCHING (SM) is attractive to both
large and small market participants and represents a competitive advantage over
other existing electronic trading systems.

     Concurrent with this offering, Cantor is contributing to us the proprietary
software, network distribution systems, technologies and related contractual
rights that comprise our eSPEED (SM) system. We will work to provide multiple
electronic markets for transactions in securities, other financial instruments
and other financial and non-financial products. Cantor will continue to provide
telephonic access for those clients who wish to trade via telephone. Clients
dealing with Cantor who prefer the more rapid and less costly method of trading
via fully electronic means will have their transactions routed through our
eSPEED (SM) system. Cantor or other third parties will provide clearing and
other transaction support services in trades in which we participate. Cantor
currently operates the largest wholesale marketplace for U.S. Treasury
securities and leading marketplaces for many other fixed income securities and
financial instruments. Cantor also operates other non-financial markets, such as
energy, commodities and acid rain emissions. We have converted 11 of

                                       30
<PAGE>
the largest Cantor marketplaces, including U.S. Treasury and European government
securities, to our electronic trading platform. We intend to convert most of
Cantor's remaining marketplaces to our electronic trading platform by the end of
2000. Cantor has been a leading global broker-dealer of fixed income securities
over the past 25 years. Cantor developed the world's first screen-based
brokerage market in U.S. government securities in 1972. Today, Cantor executes
in excess of $45 trillion in transaction volume annually and is a major
facilitator, and, in some cases, provider, of liquidity in numerous financial
products through its offices in the United States, Canada, Europe and Asia. We
believe our relationship with Cantor is a significant competitive advantage. Our
eSPEED (SM) system provides the only way to electronically access Cantor's
marketplaces. Consequently, we believe that clients will be strongly motivated
to use our interactive electronic marketplaces.

OUR INDUSTRY

     Our initial markets include global fixed income securities, futures,
options and other financial products. However, our potential markets include any
fungible products, goods or services which can be quantified and bought or sold.

     Wholesale Fixed Income Securities Trading.  The fixed income securities
market is one of the largest financial markets in the world. In the United
States alone, there are over $13 trillion of fixed income securities
outstanding, and in the U.S. Government Securities market alone, there is
reported to be approximately $200 billion a day in trading just among the
primary dealers and their clients. Other fixed income instruments are traded
widely, and in Europe, Asia and the emerging markets there are another
approximately $13 trillion of fixed income securities outstanding and trading on
a daily basis. In Europe, the creation of the Euro has manifested a market
second only to the United States in breadth. We expect continued significant
growth in these fixed income markets as the issue of currency translation is
removed as an obstacle to the development of a large unified Pan-European market
for securities.

     Futures and Options Trading.  Futures and options trading is a leading
financial activity throughout the world, with contracts traded on a wide variety
of financial instruments, commodities and indexes. Futures and options provide
several important economic benefits, including the ability to shift or otherwise
manage market risk. In part because these markets provide the opportunity for
leveraged investments, they attract large pools of risk capital. In 1998, over
1.5 billion futures contracts were traded in the world's futures markets, and
over 750 million options contracts were traded on a variety of exchanges.
Currently, most of that trading is still being done on open outcry exchanges,
but there has been a significant movement towards the conversion of these
markets to electronic trading. To date, we believe the most successful
initiatives have been made in Europe. We believe that there is significant
opportunity in the continued conversion of these markets to electronic networks,
such as our own.

     Traditional Trading Methods for Financial Marketplaces.  In both the fixed
income and futures markets, trading practices historically have centered on a
method of trading known as open outcry, where all trading activity is focused on
a central physical location, or pit. This method of trading can create
significant value for the market participants in the pit, who often have access
to better and more timely market information than other market participants. All
other market participants have to access the market through this central
location. Additionally, in order to access the pit, individuals and
institutional traders must send their orders through several layers of
middlemen, who assist in handling such orders. This process is inefficient. In
today's heavily regulated open outcry U.S. futures markets, for example, an
order can be routed through multiple people during its execution, adding
significant costs to the transaction. Virtually all U.S. futures exchanges are
controlled by their members and floor traders. Professional broker dealers,
traders, institutional traders and individuals currently must trade with these
floor members, who are the market makers. These factors result in higher direct
and indirect costs of trade execution.

                                       31
<PAGE>
TRADITIONAL ORDER EXECUTION

     Limitation of Traditional Trading Methods.  While traditional financial
markets facilitate large volume trading, they have significant shortcomings.
Direct access is substantially limited and, therefore, many investors may not
receive efficient pricing. Transaction costs are high due to the number of
people involved in an open outcry system. Execution can be slow. Program
trading, especially programs designed to automatically and simultaneously
execute multiple trades in different, but related, financial products, is
difficult to implement because of the current manual nature of these markets.
Significant expense is also incurred in processing, confirming, clearing and
implementing compliance programs designed to monitor and manage the exposure of
individual professionals, as well as the entire enterprise. Paper and
telephone-based trading produces delayed information and results in compliance
programs that are expensive to manage and can be circumvented. Therefore,
institutions bear increased risk. These factors impede trading by limiting
volume and liquidity.

     Emergence of Electronic Exchanges.  Many financial exchanges worldwide,
including certain exchanges in France, Germany, Japan, Sweden, Switzerland and
the United Kingdom, are now partially or completely electronic. In the United
States, however, trading in many types of financial instruments continues to be
conducted primarily on open outcry exchanges. Recently, many exchanges have
introduced side-by-side markets for voice and electronic access and, as a
result, have created separate pools of liquidity. Moreover, substantially all of
the electronic trading systems introduced internationally and in the United
States have been implemented on a regional basis. Most of these systems provide
limited market liquidity and are designed to accommodate trading in one or a
limited number of securities and financial products, typically equity
securities. We believe that wholesale market participants and institutions will
ultimately look for a limited number of marketplaces to meet most of their
trading needs. This is because market participants will not want to work with
multiple trading platforms and connect their information technology platforms
and compliance programs to a large number of disparate systems. We believe the
trend toward electronic trading will continue and will ultimately result in a
majority of markets worldwide becoming fully electronic.

                                       32
<PAGE>
     In addition, recently there has been considerable discussion regarding the
move toward the demutualization of exchanges. Exchanges have historically been
operated on a not-for-profit basis for the benefit of their respective members,
and this governance structure has limited their ability to adopt new
technologies and respond quickly to market changes. In response to technological
advances in trading systems, many exchanges are contemplating the reorganization
of their ownership and management structures and are seeking to form alliances
with strategic partners. These developments have created, and are expected to
continue to create, opportunities for strategic acquisitions and alliances.

     Online Trading.  Favorable investing environments and advances in
technology have led to the rapid development of online and traditional retail
brokerage businesses. Technological advances have created new and inexpensive
means for individual investors to directly access markets online and participate
in the securities markets. According to International Data Corporation, the
number of online brokerage accounts grew from approximately 1.5 million at the
end of 1996 to over 6.4 million at the end of 1998, representing $324.0 billion
in assets and over 300,000 trades per day, primarily in equity securities.
International Data Corporation also estimates that, by 2002, 30% of investors
will trade online, and there will be over 24 million online accounts, a 275%
increase from 1998. Despite the growth in online accounts and access to public
equity markets, there has been very limited access for retail Internet trading
in fixed income securities, futures, options and other wholesale financial
instruments at cost-effective pricing and spreads. We believe that the emergence
of electronic marketplaces which promote greater liquidity, enhanced access and
more efficient pricing will increase trading among retail investors.

OUR ELECTRONIC MARKETPLACE SOLUTION

     We operate a private electronic network for wholesale financial markets
through which we are connected to most of the largest financial institutions
worldwide. We have installed in the offices of our existing client base,
comprising more than 500 leading dealers, banks and other financial
institutions, the technology infrastructure necessary to provide price
information and trade execution on an instantaneous basis in abroad range of
securities and financial instruments. We believe our eSPEED (SM) system enables
us to introduce and distribute a broad mix of products and services more
quickly, cost effectively and seamlessly than competitors.

eSPEED INTERACTIVE MATCHING

                                 [GRAPHIC]

     *The above graphic is for illustrative purposes only and is not
representative of all transactions.

OUR eSPEED (SM) system:

     o has a flexible design which allows us to quickly and easily add new
       financial instruments in multiple currencies and trading models;

     o uses a network distribution system, which we believe is one of the most
       robust systems in operation, and which enables us to provide access to a
       broad mix of accurate, instantaneous market data and fast and highly
       reliable trade execution;

     o is designed to minimize the need for human intermediaries in the trading
       process by providing clients with multiple methods of accessing our
       marketplaces and executing trades directly; and

     o uses INTERACTIVE MATCHING (SM), our proprietary, rules-based trading
       method that interactively executes buy and sell orders from multiple
       market participants.

These system features enable us to operate the only integrated trading network
engaged in electronic trading in multiple products and marketplaces on a global
basis.

     The benefits of our eSPEED (SM) system include the following:

     Instantaneous Price Dissemination and Trade Execution.  Our eSPEED (SM)
system provides clients with the ability to access pricing and other information
and execute trades instantaneously, as opposed to traditional trading methods
which provide less timely information, and less efficient trade execution.

     Lower Transaction Costs.  Our eSPEED (SM) system streamlines the entire
trading process by eliminating the significant layers of manual intervention
which currently exist at both the front-end of the process, including order
entry, matching and postings functions, as well as at the middle and back-end of
the process (clearance, settlement, tracking and reporting functions), resulting
in significantly lower transaction costs for our clients.

     Multiple Product Program Trading.  Our eSPEED (SM) system provides our
clients with the ability to execute sophisticated and complex transactions and
trading strategies, including the trading of multiple products across multiple
markets simultaneously.

                                       34
<PAGE>
     Greater Accuracy and Decreased Probability of Erroneous Trades.  Our
eSPEED (SM) system includes verification mechanisms at various stages of the
execution process, which result in significantly reduced manual intervention,
decreased probability of erroneous trades and more accurate execution for
clients.

     Integrated Compliance and Credit Risk Functions.  Our eSPEED (SM) system
includes a comprehensive range of compliance and credit risk management
components which perform several critical functions, including:
(1) continuously monitoring trading activity to ensure that clients are staying
within credit limits; (2) automatically preventing further trades once credit
limits have been exceeded; and (3) evaluating and calculating positions and risk
exposure across various products and credit limits. These risk, credit and
compliance tools are highly sophisticated and can be customized for our clients
and integrated into their information technology platforms.

     Highly Efficient Pricing on Illiquid Securities.  Our MOLE system enables
us to provide prices for illiquid financial products through multiple trades in
other related financial instruments. These multi-variable trades are extremely
difficult to execute in traditional markets due to their complexity and the slow
speed of manual execution.

     Ability to Automate Back-Office Functions.  Our eSPEED (SM) system
automates previously paper and telephone-based transaction processing,
confirmation and other functions, substantially improving and reducing the cost
of client back-offices, and enabling straight-through processing.

     Improved Access for Online Retail Brokers.  Our eSPEED (SM) system enables
online and traditional retail brokers to provide clients with real-time access
to previously unavailable wholesale marketplaces for fixed income securities,
futures, options and other financial instruments. We believe that this will
increase retail interest in the trading of these financial products and further
enhance the overall liquidity and efficiency of the market.

     We believe our eSPEED (SM) system provides us with significant competitive
advantages over existing electronic trading systems and new entrants seeking to
develop and introduce limited electronic trading systems to the global
securities and financial instruments marketplaces. We also believe that the time
and expense required to develop and install electronic trading networks will
serve as a significant barrier to entry to many other potential competitors.

OUR GROWTH STRATEGY

     Our objective is to be the leading provider of interactive electronic
marketplaces in the world. We believe we can extend our expertise in the
creation of real-time electronic marketplaces to a broad range of financial and
non-financial products and services. Our growth strategy to achieve this
objective includes the following key elements:

     Focus Exclusively on Developing and Operating Interactive Electronic
Marketplaces.  We intend to capitalize on the trend toward the increased use of
electronic trading platforms by focusing our business exclusively on the
development and operation of interactive electronic marketplaces worldwide. We
believe this operational focus provides us with a significant advantage over
competitors that have multiple and sometimes conflicting business objectives,
rigid business practices and cumbersome ownership structures that may impede
their ability to efficiently develop and implement electronic trading platforms
of their own.

     Expand the Number of Financial and Non-Financial Products in Our Electronic
Marketplaces.  Our electronic marketplaces currently handle the trading of
financial products which have among the highest average annual trading volumes
of all financial products, including U.S. government securities, U.S. Treasury
futures, non-U.S. G-7 government bonds, Eurobonds, corporate bonds, agency
securities, U.K. gilts, emerging markets securities, U.S., European and other
repurchase agreements and municipal bonds. We plan to significantly expand the
types of securities and financial products traded in our marketplaces. Our goal
is to include in our electronic marketplaces the full range of fixed income
securities, futures, options and other securities and financial products that
are currently traded in today's markets worldwide. Initially, we will focus our
expansion efforts on the securities and financial instruments traded by Cantor
that have not yet been converted to electronic trading. We expect to further
extend our marketplaces to include additional

                                       35
<PAGE>
financial and non-financial products through a variety of approaches together
with Cantor or other strategic partners.

     Convert Clients to Fully Electronic Trading.  Currently, less than 4% of
the trades executed in our marketplaces, representing more than $6 billion in
volume, are executed on a fully electronic basis without the assistance of a
broker. We intend to continue to convert substantially all of Cantor's clients
to a fully electronic trading environment. We believe the ease of use, low price
and efficient execution that our electronic marketplaces afford will encourage
clients to convert their trading to fully electronic trading. We have a team of
over 30 persons dedicated to enhancing client awareness of the advantages of
electronic trading and providing client support in converting trading activity
to a fully electronic trading format, and we intend to increase that number. We
also expect to leverage Cantor's historical client relationships in connection
with these efforts.

     Leverage Existing eSPEED (SM) System Connectivity to Deploy New Products
and Services.  Our eSPEED (SM) system provides connectivity to, and the
opportunity to electronically interact with, a global client base that includes
dealers, banks and financial institutions at hundreds of sites around the globe.
As a result, a significant number of our major clients currently have installed
the hardware necessary to trade on a fully electronic basis. Utilizing the
existing infrastructure and flexible architecture of this system, we will be
able to install with relative ease and at marginal incremental cost, the
components that will enable a client to electronically trade in additional types
of securities and financial products. We expect access to this existing global
private trading network to enable us to introduce and distribute a broad mix of
electronic trading products and services, more quickly, cost effectively and
seamlessly than competitors without access to such a network.

     Creating Online Retail Broker Access to Wholesale Markets for Fixed Income
Securities and Other Financial Products.  We intend to create retail
marketplaces, where appropriate, to enable online and traditional retail brokers
to provide their clients with real-time access to previously unavailable
wholesale marketplaces for retail trading of fixed income securities, futures,
options and other financial instruments. While retail investors generally have
been able to buy and sell equity securities at the same prices and spreads as
wholesale market participants and institutional investors, this has not been the
case with fixed income securities, futures, options and other financial
instruments. We believe our eSPEED (SM) system will expand marketplaces and/or
retail volume and enhance execution for individual retail investors.

     Pursue Acquisitions and Strategic Alliances.  We intend to capitalize on
the highly fragmented nature of the financial marketplaces and the trends toward
exchange demutualization and consolidation among regional and global market
participants. We expect to pursue an acquisition-based growth program that will
enable us (1) to acquire complementary technologies and service capabilities in
a cost-effective manner and (2) to broaden our product base and the securities
markets in which we provide our electronic trading services. We will seek to
enter into joint ventures and other strategic alliances to create additional
liquidity in the global financial products markets and to attract new trading
participants to those markets. We believe the flexibility afforded by our
corporate governance structure will enable us to implement these strategies, as
well as to anticipate and respond to developments and trends in the global
financial markets, more efficiently than competitors, such as exchanges, which
have broadly dispersed memberships and cumbersome management structures.

     Leverage Our eSPEED (SM) System for Use in Other Business-to-Business and
Consumer Markets.  We believe that our eSPEED (SM) system is easily adaptable to
other products. Because of the scale of the system and its ease of adaptability,
we believe our eSPEED (SM) system and INTERACTIVE MATCHING (SM) will have
applications across a broad range of products, including Internet-based
marketplaces for a wide array of consumer goods and services, particularly those
involving multiple buyers and sellers. We are well positioned to leverage
significant costs and efforts which have been incurred to develop our
eSPEED (SM) system to quickly create electronic markets in a wide range of
products.

OUR TRADING SERVICES AND TECHNOLOGY PLATFORM

     Electronic marketplaces are emerging as significant interactive mediums for
trading financial and non-financial products. In an electronic marketplace,
substantially all of the participants' actions are facilitated through an
electronic medium, such as a private electronic network or the Internet, which
limits the need for actual face-to-face or voice-to-voice participant
interaction.

     In our electronic marketplaces, participants may either electronically
execute trades themselves or call brokers/terminal operators who input trade
orders for them. In a fully electronic trade, all stages of the trade occur
electronically. The participant inputs its order instructions directly into our
electronic trading system, using a keyboard, an application programming
interface or other software. The system provides to the participant, normally
within 300 milliseconds, an on-screen confirmation that the participant's order
has been accepted. Once a trade is executed, the participant receives an
on-screen trade confirmation. Simultaneously, an electronic confirmation is sent
to the participant's back office system enabling straight-through processing for
the participant. A broker/terminal operator assisted trade is executed in
substantially the same manner as an electronic trade, except the participant
telephones a broker/terminal operator who inputs the participant's order into
our electronic marketplace system.

     Over time, we expect electronically brokered trading to be the predominant
trading method in our marketplaces. However, through our affiliation with
Cantor, we intend to maintain broker/terminal operator trading capabilities.
Unlike most traditional exchanges which have created side-by-side markets for
voice and electronic access and, as a result, have created separate pools of
liquidity, our markets operate seamlessly. Fully electronic and broker/terminal
operator orders are transacted within our eSPEED (SM) system, resulting in one
pool of liquidity. Retail investors will participate in our online marketplaces
for financial products through their online or traditional retail broker. Retail
investors will follow their retail brokers' order entry procedures. Once a
retail broker confirms its client's account status, suitability and
creditworthiness, our systems will route the online order to our appropriate
electronic marketplace. We will receive transactional fees from retail brokers
for enabling their retail clients to trade online in our marketplaces.

     Our electronic marketplaces operate on a proven technology platform that
emphasizes scalability, performance and reliability. Our technology platform
consists of:

     o a proprietary, internally developed network distribution system,

     o transaction processing software which includes a proprietary order
       matching engine, a credit and risk management system, security pricing
       engines and associated middle and back office operations systems; and

     o client interfaces.

     Together, these components enable banks, broker-dealers, and other
participants in our marketplaces to cost-effectively trade financial products on
an instantaneous basis.

     Network Distribution System.  Our eSPEED (SM) system contains a
proprietary, sophisticated, hub and spoke digital network. This network uses
Cisco Systems network architecture and has points of presence in the major
financial hubs of the world, including New York, London, Tokyo, Frankfurt,
Paris, Milan, Chicago, Los Angeles, Toronto and Johannesburg. It is comprised of
over 50,000 miles of cable and over 800 network routers and uses 200 high
capacity super servers. This internally designed distribution network provides
connections with over 500 financial institutions, including most of the largest
financial institutions in the world. The redundant structure of the system
provides backup and re-routing of data transmission if one spoke of a hub fails.
This backup is critical to maintaining our clients' real-time connections to us.
We believe it is one of the largest and most robust interactive network
distribution systems currently in operation.

     Our distribution system accepts orders and postings instantaneously and
distributes responses, generally in 300 milliseconds. The network can transport
150 million bits of information per second around the world and is currently
running at approximately 12% of capacity. In addition to our own network system,
we also distribute encrypted data and receive trading information from clients
using the services of multiple, major Internet service providers throughout the
world. These connections enable us to offer Internet-based trading to our global
clients.

     Transaction Processing Software.  Our software applications have been
developed internally and are central to our eSPEED (SM) system. Our order
matching trading engines operate in real-time, facilitating efficient
interaction between buyers and sellers. Our credit and risk management systems
monitor and regulate these buyers and sellers, limiting market and credit risk.
Our pricing engines provide prices for illiquid financial products through
multiple trades in other related financial instruments. These three critical
applications work together seamlessly and are supported by middle and back
office software that verifies, confirms, reports, stores, tracks and, if
applicable, clears each trade.

     o Trading Engines.  Our trading engines use INTERACTIVE MATCHING (SM), our
       proprietary rules-based method, to process in excess of 150 transactions
       per second per product. These engines were developed to support trading
       of homogeneous products, which are products with the same underlying
       characteristics, such as government bonds and futures contracts, and
       heterogeneous products, which are products which may be similar, but
       which have some aspects that differentiate them from other products in
       the same class, such as municipal bonds, corporate bonds and Eurobonds.
       These trading engines are designed to be modular and flexible to allow
       modification in order to apply them to other markets. In Europe, for
       example, we have added a component that allows us to process the trading
       of debt in multiple currencies. Our trading engines have embedded
       security features and an added messaging layer to provide security from
       unauthorized use. In addition, we use encryption to protect our clients
       that trade over the Internet. When used together, our trading engines can
       trade a wide range of homogeneous and heterogeneous products and can
       handle trades ranging in size from $1,000 to billions of dollars.

     We believe our systems provide incentives for clients to actively
     participate in our marketplaces. For example, INTERACTIVE MATCHING (SM)
     provides incentives to participate in our marketplaces by encouraging
     participants to expose their orders to the market by providing them
     priority in the interactive marketplace. In standard auctions, the
     incentive is for participants to wait until the last moment to make a bid
     or offer. Our priority rules encourage trading activity by giving the last
     successful active participant a time-based right of first refusal on the
     next sale/purchase. In addition, in many markets we have structured our
     pricing policy to provide that the party that provides market liquidity by
     inputting a price to buy or sell pays less commission (or no commission)
     than the participant that acts on that price. With our pricing policies and
     proprietary priority rules, our system is designed to increase activity and
     to draw participants into the market. This proprietary rules-based system
     is easily adaptable and, as part of our business strategy, we intend to
     apply it in other non-financial markets for a variety of products and
     services.

     o Credit and Risk Management Systems.  Our credit and risk management
       systems are critical to the operation of our real-time, electronic
       marketplaces. Our proprietary credit and risk management systems perform
       a variety of functions: (1) they continuously monitor trades of our
       clients to ensure that they have not exceeded their credit limits,
       (2) they can automatically prevent further trading once a client has
       reached a pre-determined credit limit, and (3) they can evaluate trade
       transactions and calculate both individual positions and risk exposure
       across various products and credit limits. These systems can also be made
       available to our global clients to enable them to monitor the position of
       their traders and their clients who participate in our marketplaces.
       These systems store client data relevant to credit and risk management,
       such as financial statements, credit documents, contacts and internal
       analyses. These systems also enable our clients to make our electronic
       marketplaces available to their clients while maintaining control of
       their trading activity and risk.

     o Pricing Engines.  We have internally developed a number of sophisticated,
       analytical software tools that permit us to price financial products that
       trade in less liquid markets and for which current pricing information is
       not readily available. For example, MOLE is a computer application that
       enables us to offer prices and therefore create and enhance a marketplace
       for financial products that have limited liquidity. MOLE currently uses
       data from existing cash and futures markets to calculate pricing for
       transactions where no market prices currently exist.

     o Middle and Back Office Applications.  Our middle and back office
       applications support clearance, settlement, tracking and reporting of
       trades and provide links to outside entities such as the

                                       38
<PAGE>
       Government Securities Clearance Corporation, National Securities
       Clearance Corporation, Depository Trust Company, SWIFT, Euroclear, New
       York Clearing Corp. and most other global clearing organizations. In the
       financial markets, clearance and settlement is the process by which a
       security and cash payment are exchanged and the trade is completed. In
       some markets, the cash and security are both passed to a clearing
       organization for settlement. In other transactions, both parties send
       either cash or a security to Cantor and Cantor settles the trade and
       sends each party the cash or security due. Our reporting and accounting
       systems are designed to ensure that all charges and commissions for a
       trade are tracked and recorded. Our accounting systems are designed to
       ensure that books and records are kept in accordance with regulatory
       guidelines and accounting standards.

Client Interfaces.  Our systems can be accessed by our clients in four ways:

     o using our eSPEED (SM) proprietary software;

     o using our application programming interface to write their own software
       linking their networks and software applications directly to our systems;

     o through our proprietary, real-time private distribution system and the
       Internet, both for wholesale clients and for retail clients who
       participate in our marketplaces through online and traditional retail
       brokers; and

     o through software developed in alliances with third-party vendors such as
       QV Trading and SunGard/ASC. Our application programming interface enables
       clients to conduct computer price updating, program trading and
       straight-through processing.

SALES AND MARKETING

     We expect to promote our electronic marketplaces and brokerage-related
services to Cantor's existing clients and new clients through a combination of
sales, advertising, marketing and co-marketing campaigns. We also expect to
leverage the historical client relationships of Cantor's employees under the
Joint Services Agreement. We intend to build and enhance the eSPEED (SM) brand
name recognition through a sales, advertising and marketing campaign. We expect
to market to retail clients through a variety of campaigns, including
co-marketing campaigns with our online and traditional retail brokers. We intend
to design our sales, marketing and advertising campaigns to promote brand
awareness and educate the marketplace regarding the nature of our electronic
marketplaces, products and services and the advantages associated with the
automation of trading activities, such as enhanced instantaneous information
flow, price transparency and more direct and cost-effective market access, tight
spreads and instantaneous trade execution.

OUR CLIENTS

     Clients for our marketplaces include banks, dealers, brokers and other
wholesale market participants, over 500 of which currently participate in our
electronic marketplaces, including the 25 largest bond trading firms in the
world, as identified by Euromoney Magazine. Through our eSPEED (SM) system, we
expect to enable retail brokerage firms to expand their businesses by providing
them with the ability to offer their individual clients the option of trading
bonds and futures electronically in the same way they trade equity securities
and we expect to include other marketplaces previously unavailable to retail
investors, or not available to them at reasonable spreads or commissions. We
intend to provide to wholesale and retail investors and to Cantor access to our
electronic marketplaces and brokerage-related services supported by our
eSPEED (SM) system. We expect that a significant portion of our clients who use
brokers will migrate to fully electronic access over the coming years. We also
intend to provide to third parties and to Cantor the infrastructure, including
systems administration, internal network support and operations and disaster
recovery services, that is critical to providing fully electronic marketplaces
for trading in a wide range of financial products. Other than Cantor, no client
of ours accounts for more than 10% of our revenues.

STRATEGIC ALLIANCES

     In 1997, Cantor entered into an agreement with the New York Cotton
Exchange, which, upon merging with the Coffee, Sugar & Cocoa Exchange, became
known as the New York Board of Trade. The agreement sets forth the terms and
conditions pursuant to which Cantor operates an electronic marketplace, called
the CANTOR EXCHANGE (SM), for futures contracts cleared by and under the
regulatory supervision of the New York Board of Trade. Cantor has assigned to us
all of its rights and obligations under its agreement with a subsidiary of the
New York Board of Trade to jointly operate the CANTOR EXCHANGE (SM). Under the
agreement, the New York Board of Trade, through its subsidiaries, provides
clearing and regulatory services and we provide electronic execution and related
services for the CANTOR EXCHANGE (SM).

     Pursuant to the agreement, neither we nor our affiliates shall during the
term of the agreement establish in the United States an electronic market for
trading futures contracts or options on futures contracts on cotton, cheese,
coffee, sugar, cocoa, milk or frozen orange juice. We have agreed that within
the United States we shall exclusively operate for the CANTOR EXCHANGE (SM)
markets for U.S. Treasury futures and other products so designated by the CANTOR
EXCHANGE (SM). We and our affiliates may establish any electronic market that is
located physically outside the United States for such products if the New York
Board of Trade is not capable of providing regulatory or clearing services with
respect to such products.

SOFTWARE DEVELOPMENT

     We devote substantial efforts to the development and improvement of our
electronic marketplaces. We will work with our clients to identify their
specific needs and make modifications to our software, network distribution
systems and technologies which are responsive to those needs. We are pursuing a
four-pronged approach to our research and development efforts: (1) internal
development; (2) strategic partnering; (3) acquisitions; and (4) licensing. We
have approximately 150 persons involved in our internal software development
efforts. Our technology team's objective will be to develop new products and
services that employ proven technology designed to provide superior electronic
trade execution and marketplace services to our clients. We will also focus our
efforts on enhancing our Web site and Internet screen interface to

                                       43
<PAGE>
facilitate real-time markets, comply with the standard Internet security
protocol and future security protocols and migrate transactions to the public
networks in order to capitalize on the development of new commercial
marketplaces. We are continuing to develop new marketplaces and products using
our internally developed application software having open architecture and
standards. In addition, we have forged strategic alliances with organizations
such as Sungard/ASC and QV Trading through which we will work to develop
sophisticated, front-end trading applications and products. We expect to license
products from and to companies when it is cost effective or profitable to do so.

COMPETITION

     The development and operation of electronic trading marketplaces in
securities and other financial instruments are evolving. As a result,
competition in these marketplaces is currently very fragmented. We expect to
face competition from a number of different sources varying in size, business
objectives and strategy. Our eSPEED (SM) system currently competes, and we
expect it to compete, directly and indirectly, with:

     o traditional trading methods, including manual buy/sell order input by
       registered brokers in response to telephone originated requests and
       execution of trades in open outcry trading pits on exchange floors, such
       as the Chicago Board of Trade, the Chicago Mercantile Exchange and other
       exchanges and over-the-counter markets;

     o products developed and used by exchanges and financial services firms,
       such as Liberty Brokerage Investment Corporation and Garban-Intercapital
       plc, seeking to act as market intermediaries;

     o automated trade execution services developed by third party vendors for
       commercialization in a wide range of financial products markets;

     o the products and services of market data, information and communication
       vendors, such as Reuters Group plc, Bloomberg L.P. and Bridge Information
       Systems Inc., that have created electronic networks which link them to
       most major financial institutions and that have attempted, in some cases,
       to expand their networks to include trading platforms;

     o consortia comprised of leading financial institutions and service
       providers, such as BrokerTec Global LLC, which has announced its
       intention to explore the development of electronic trading networks, and
       EuroMTS; and

     o in the event we extend the application of our INTERACTIVE MATCHING (SM)
       technology to conducting or facilitating real-time markets in
       commodity-type consumer goods and services over the Internet, both online
       and traditional sellers of these products and services.

     The electronic trading services we provide our wholesale clients enable
them to expand the range of services they provide to their ultimate clients,
which are also potential participants in our electronic marketplaces. We intend
to structure our relationships with our clients and conduct our operations to
mitigate the potential for this competition. We do not intend to use the access
to the customer base of our wholesale clients that we obtain in providing our
electronic trading services to compete with these wholesale clients in other
securities and financial instrument transactions.

     We believe our electronic marketplaces will compete primarily on the basis
of speed, efficiency, price and ability to provide access to liquidity to market
participants.

OUR INTELLECTUAL PROPERTY

     We have adopted a comprehensive intellectual property protection program to
protect our proprietary technology. We currently have licenses covering four of
Cantor's patents in the United States. One patent relates to a data processing
system and method for electronically trading select items such as fixed income
instruments. Two patents relate to a fixed income portfolio index processor. One
patent relates to a system for shared remote access of multiple application
programs by one or more computers. Foreign counterpart applications for some of
these U.S. patents have been filed. The licenses are exclusive, except in the
event that we do not seek to or are unable to provide to Cantor any requested
services covered by the patents and Cantor elects not to require us to do so.

                                       44
<PAGE>
     We also have an agreement to license several pending U.S. patent
applications relating to various other aspects of our electronic trading
systems, including both functional and design aspects. Additional patent
applications likely will be filed in the near future to further protect our
proprietary technology.

     We cannot at this time determine the significance of any of the foregoing
patents, or future patents, if issued, to our business. We can give no assurance
that any of the foregoing patents is valid and enforceable, or that any of these
patents would not be infringed by a third party competing or seeking to compete
with our business.

REGULATION

     The securities industry and financial markets in the United States and
elsewhere are subject to extensive regulation. As a service provider to the
securities industry and financial markets, and as a registered broker-dealer,
our business activities fall within the scope of these regulations.

     Regulation of the U.S. Securities Industry and Broker-Dealers.

     As a matter of public policy, regulatory bodies in the United States and
the rest of the world are charged with safeguarding the integrity of the
securities and other financial markets and with protecting the interests of
investors participating in those markets. In the United States, the Securities
and Exchange Commission is the federal agency responsible for the administration
of the federal securities laws. Our regulated U. S. subsidiaries, eSpeed
Securities, Inc. and eSpeed Government Securities, Inc., are registered with the
Securities and Exchange Commission as, respectively, a broker-dealer and a
government securities broker. They are also members of the National Association
of Securities Dealers, Inc., a self regulatory body to which most broker-dealers
belong. Certain self-regulatory organizations, such as the National Association
of Securities Dealers, Inc., adopt rules and examine broker-dealers and require
strict compliance with their rules and regulations. The Securities and Exchange
Commission and self-regulatory organization rules cover many aspects of a
broker-dealer's business, including capital structure and withdrawals, sales
methods, trade practices among broker-dealers, use and safekeeping of customer's
funds and securities, record-keeping, the financing of clients' purchases,
broker-dealer and employee registration and the conduct of directors, officers
and employees. In connection with a violation of these rules, the SEC,
self-regulatory organizations and state securities commissions may conduct
administrative proceedings which can result in censure, fine, the issuance of
cease-and-desist orders or the suspension or expulsion of a broker-dealer, its
officers or employees.

     Effect of Net Capital Requirements.  As a registered broker-dealer and
member of the National Association of Securities Dealers, Inc., eSpeed
Securities, Inc. is subject to the Uniform Net Capital Rule under the Exchange
Act. The Uniform Net Capital Rule specifies the minimum level of net capital a
broker-dealer must maintain and also requires that at least a minimum part of
its assets be kept in relatively liquid form. Government securities brokers must
comply with similar net capital requirements established in rules promulgated by
the U.S. Treasury Department. As of September 24, 1999, if each of our regulated
U.S. subsidiaries, eSpeed Securities, Inc. and eSpeed Government Securities,
Inc., had been subject to the Uniform Net Capital Rule, the minimum net capital
required of each would have been $5,000 and $25,000, respectively. As of that
date, each of our U.S. subsidiaries had total net capital of approximately
$90,000, or $85,000 and $65,000, respectively, in excess of the minimum amount
that would have been required as of that date.

     The Securities and Exchange Commission and the National Association of
Securities Dealers, Inc. impose rules that require notification when net capital
falls below certain predefined criteria, dictate the ratio of debt to equity in
the regulatory capital composition of a broker-dealer and constrain the ability
of a broker-dealer to expand its business under certain circumstances.
Additionally, the Uniform Net Capital Rule and the National Association of
Securities Dealers, Inc. rules impose certain requirements that may have the
effect of prohibiting a broker-dealer from distributing or withdrawing capital
and requiring prior notice to the Securities and Exchange Commission and the
National Association of Securities Dealers, Inc. for certain withdrawals of
capital. Because our principal asset will be the ownership of stock in our
broker-dealer subsidiaries, these rules governing net capital and restrictions
on withdrawals of funds could operate to prevent us from meeting our financial
obligations on a timely basis.

     Application of Exchange Act to Internet Business.  The Securities Exchange
Act of 1934 governs, among other things, the operation of the financial products
markets and broker-dealers. When enacted, the

                                       45
<PAGE>
Securities Exchange Act of 1934 did not contemplate the conduct of a securities
business throughout the Internet. Although the Securities and Exchange
Commission, in releases and no-actions letters, has provided guidance on various
issues related to the conduct of a securities business through the Internet, the
application of the laws to the conduct of a securities business through the
Internet continues to evolve. Uncertainty regarding these issues may adversely
affect the viability and profitability of our business.

     Financial Futures and Options.  Financial futures and options in financial
futures are subject to regulation by the Commodity Futures Trading Commission
under the Commodity Exchange Act, and exchanges that provide facilities for the
trading of those products are also subject to Commodity Futures Trading
Commission regulation. As a service provider to the CANTOR EXCHANGE (SM), a
futures exchange that is a designated contract market under the Commodity
Exchange Act, we could be adversely affected by changes in laws or regulations
governing the products or clients of the CANTOR EXCHANGE (SM).

     Exchange Regulation.  Securities exchanges must register with the
Securities and Exchange Commission and comply with various requirements of the
Securities Exchange Act of 1934. Effective April 1999, new rules expanded the
scope of exchange regulation to include many brokerage matching and execution
systems, such as the matching systems which we support. The new rules impose
various requirements relating to fair access, capacity, security, record-keeping
and reporting. Our subsidiaries expect to comply with these requirements.
Although we do not expect the compliance costs to be significant, our
subsidiaries could encounter unforseen expenses associated with operation of
these rules.

     Regulation of the Non-U.S. Securities Industries and Investment Service
Providers.

     The securities industry and financial markets in the European Union and
elsewhere are subject to extensive regulation. As the owner and operator of
electronic marketplaces for the securities industry and financial markets, our
business activities may fall within the scope of those regulations depending
upon the extent to which we are characterized as providing a regulated
investment service.

     The securities industry in the member states of the European Union is
extensively regulated by agencies in each member state. European Union measures
provide for the mutual recognition of regulatory agencies and of prudential
supervision making possible the grant of a single authorization for the provider
of investment services which, broadly, is valid throughout the European Union.
As an investment service provider in the United Kingdom, our principal regulator
would be the Securities and Futures Authority. The conduct of an investment
business is also regulated by agencies in each of the other member states in
which we may provide investment services. The provision of investment services
is also regulated by other agencies in other jurisdictions in which we operate
such as the Securities and Futures Commission in Hong Kong and the local
government agency delegated by the Japanese Financial Supervisory Agency in
Japan.

     As a matter of public policy, regulatory bodies in the European Union and
the rest of the world are charged with safeguarding the integrity of the
securities and other financial markets and with protecting the interests of
investors participating in those markets. We are seeking authorization from the
Securities and Futures Authority to provide investment services in the United
Kingdom and we intend to exercise our rights under the European Union Investment
Services Directive to provide such investment services throughout the European
Union. Similar authorization applications will be made in other jurisdictions
such as Hong Kong and Japan where such authorization is necessary to operate an
electronic marketplace.

     The Securities and Futures Authority and other regulatory agencies in the
European Union may conduct administrative proceedings which can result in
censure, fine, the prevention of activities or the suspension or expulsion of an
investment services provider. The applicable investment service regulations
cover minimum financial resource requirements and conduct of business rules for
all authorized investment businesses.

     Investment exchanges may be operated and authorized as investment
businesses in the European Union, subject to the provision of the Investment
Services Directive. Alternatively, investment exchanges can obtain authorization
as an investment exchange from each member state in the European Union in
accordance with the applicable regulations of that member state.

     Changes in Existing Laws and Rules.  Additional legislation or regulation,
changes in existing laws and rules or changes in the interpretation or
enforcement of existing laws and rules, either in the United States or
elsewhere, may directly affect our mode of operation and our profitability.

                                       46

LEGAL PROCEEDINGS

     On May 5, 1999, Cantor Fitzgerald, L.P. and The Board of Trade of the City
of Chicago, The New York Mercantile Exchange and The Chicago Mercantile Exchange
were sued by Electronic Trading Systems Corporation in the United States
District Court for the Northern District of Texas (Dallas Division) for alleged
infringement of Wagner United States patent 4,903,201, entitled "Automated
Futures Trade Exchange." The patent relates to a system and method for
implementing an electronic, computer-automated futures exchange. On July 1,
1999, Cantor answered the complaint, asserting, among other things, that the
'201 patent was invalid and not infringed by Cantor and that Cantor was not the
real party in interest. Although not identified by the complaint, Cantor
believes that the system being charged with infringement is a version of the
electronic trading system used by the CANTOR EXCHANGE (SM), which Cantor is
contributing to us in connection with this offering. If the plaintiff is
successful in the lawsuit, we may be required to obtain a license to develop and
market one or more of our services, to cease developing or marketing services or
to redesign these services. We cannot assure you that we would be able to obtain
these licenses or that we would be able to obtain them at commercially
reasonable rates or, if unable to obtain licenses, that we would be able to
redesign our services to avoid infringement.


     On June 21, 1999, Cantor and its affiliate CFPH, LLC, brought suit against
Liberty Brokerage Investment Corporation and Liberty Brokerage Inc. in the
United States District Court for the District of Delaware for infringement of
the Fraser et al. U.S. patent 5,905,974, entitled "Automated Auction Protocol
Processor." Cantor alleged in the complaint that Liberty was infringing the '974
patent by making, using, selling and/or offering for sale systems and methods
that embody or use the inventions claimed in the '974 patent. On August 10,
1999, Cantor and CFPH, L.L.C. voluntarily dismissed the suit without prejudice.
Subsequently, on August 10, 1999, Liberty filed an action for declaratory
judgment in the United States District Court for the District of Delaware
against Cantor and two of its affiliates, Cantor Fitzgerald Securities and CFPH,
LLC, claiming that the '974 patent was invalid, unenforceable and not infringed
by Liberty. On October 12, 1999, Cantor, Cantor Fitzgerald Securities and CFPH,
LLC moved (1) to dismiss all claims against Cantor Fitzgerald Securities for
failure to state a claim upon which relief can be granted and (2) to dismiss the
action as against Cantor, Cantor Fitzgerald Securities and CFPH, LLC for lack of
an actual case or controversy within the meaning of 28 U.S.C. Section 2201. On
November 22, 1999, the Court granted the motion to dismiss the action as against
Cantor Fitzgerald Securities, and denied the motion to dismiss the action as
against Cantor and its affiliate CFPH, LLC. We cannot assure you that we or
Cantor will bring a claim for infringement of the '974 patent against Liberty,
that the '974 patent will be found to be valid and/or enforceable or that
Liberty will be found to have infringed the '974 patent. We have assumed
responsibility for defending this suit on behalf of Cantor and its affiliates
and the risk of loss associated with it.

     In February 1998, Market Data Corporation contracted with Chicago Board
Brokerage (a company controlled by the Chicago Board of Trade and Prebon Yamane)
to provide the technology for an electronic trading system to compete with
Cantor's United States Treasury brokerage business. Market Data Corporation is
controlled by Iris Cantor and Rodney Fisher, her nephew-in-law. Iris Cantor, a
company under the control of Iris Cantor referred to herein as CFI, and Rodney
Fisher are limited partners of Cantor Fitzgerald, L.P.

     In April 1998, Cantor Fitzgerald, L.P. filed a complaint in the Delaware
Court of Chancery against Market Data Corporation, Iris Cantor, CFI, Rodney
Fisher and Chicago Board Brokerage seeking an injunction and other remedies. The
complaint alleges that Iris Cantor, CFI and Rodney Fisher violated certain
duties, including fiduciary duties under Cantor's partnership agreement due to
their competition with Cantor Fitzgerald, L.P. with respect to the electronic
trading system mentioned above. The complaint further alleges that Market Data
Corporation and Chicago Board Brokerage tortiously interfered with Cantor's
partnership agreement and aided and abetted Iris Cantor's, CFI's and Rodney
Fisher's breaches of fiduciary duty. Iris Cantor, CFI and Rodney Fisher
counterclaimed seeking, among other things, (1) to reform agreements they have
with Cantor Fitzgerald, L.P. and (2) a declaration that Cantor Fitzgerald, L.P.
breached the implied covenant of good faith and fair dealing. Cantor has agreed
to indemnify us for any liabilities that we incur with respect to any current or
future litigation involving (1) Market Data Corporation, (2) Iris Cantor, (3)
CFI or (4) Rodney Fisher.

                                       47

     On July 12, 1998, the Court of Chancery held Cantor Fitzgerald, L.P. was
likely to succeed on the merits of its claims that Iris Cantor, CFI and Rodney
Fisher had breached their partnership obligations to Cantor but had not shown
that the defendants' conduct was likely to cause imminent irreparable harm
between the date of the opinion and a final hearing. The Court of Chancery,
therefore, denied Cantor Fitzgerald, L.P.'s request for preliminary injunctive
relief and scheduled a final trial. Cantor Fitzgerald, L.P. settled its dispute
with Chicago Board Brokerage in April 1999 and Chicago Board Brokerage
subsequently announced it was disbanding its operations. The remaining parties
have completed the final trial and the Court of Chancery's decision is expected
following post-trial oral arguments scheduled for December 7, 1999. We believe
Market Data Corporation's technology for electronic trading systems will be of
substantial assistance to competitors in the wholesale market if provided to
them.

     Two related actions are pending in New York. In a case pending in the
Supreme Court of New York, New York County, plaintiff Cantor Fitzgerald, L.P.
alleges, among other things, that defendants Market Data Corporation, CFI, Iris
Cantor and Rodney Fisher misused confidential information of Cantor Fitzgerald,
L.P. in connection with the above mentioned provision of technology to Chicago
Board Brokerage. In a case pending in the United States District Court for the
Southern District of New York, CFI and Iris Cantor allege, among other things,
that certain senior officers of Cantor Fitzgerald, L.P., breached fiduciary
duties they owed to CFI. The allegations in this lawsuit relate to several of
the same events underlying the court proceedings in Delaware. Neither of these
two cases has been pursued during the pendency of the court proceedings in
Delaware.

     In addition to the allegations set forth in the pending lawsuits, Cantor
has received correspondence from the attorneys representing Iris Cantor, CFI,
Market Data Corporation and Rodney Fisher in the proceedings in Delaware,
expressing a purported concern that Cantor and/or certain of its partners may be
in breach of Cantor's partnership agreement (including, among other things, the
partnership agreement's provisions relating to competition with the partnership)
and the general partnership agreement of Cantor Fitzgerald Securities with
respect to our initial public offering. Generally, these attorneys have alleged
that various purported conflicts of interest will exist arising from the fact
that certain of our directors and officers will simultaneously hold positions
with Cantor Fitzgerald, L.P. Moreover, these attorneys have asserted that our
business plan may not be consistent with certain purported rights of Market Data
Corporation (including purported intellectual property rights) and other parties
and they have requested more information regarding our initial public offering.

     Although we do not expect to incur any losses with respect to the pending
lawsuits or supplemental allegations surrounding Cantor's partnership agreement,
Cantor has agreed to indemnify us with respect to any liabilities we incur as a
result of such lawsuits or allegations.

     Cantor and Reuters are parties to a confidential arbitration under the
auspices of the American Arbitration Association in New York, New York, which
began in June of 1995 with respect to a January 1993 agreement among Reuters,
Cantor and Market Data Corporation. Cantor has agreed to indemnify us against
all claims asserted by Reuters or Market Data Corporation relating to this
agreement or arising out of the arbitration.


     The agreement executed in 1993 involves, among other things, the delivery
by Cantor of certain market data arising out of non-United States government
bond and U.S. municipal bond interdealer brokerage transactions for transmittal
over Reuters' network. The agreement also contemplated the joint development by
Cantor and Reuters of an electronic trading system for certain transactions in
non-United States government bonds. Cantor and Reuters did not develop this
electronic trading system. In the arbitration, Reuters alleges that Cantor
materially breached the agreement primarily by failing to provide non-screen,
voice brokerage data concerning non-United States government bonds and U.S.
municipal bonds that Reuters contends are subject to the agreement and fraud.
Reuters is seeking to recover from Cantor amounts representing past payments for
market data, the reimbursement of attorneys' fees and other damages. Cantor has
denied Reuters' allegations that there has been any material breach of this
agreement or fraud, and has asserted a breach of contract claim and various
other counterclaims against Reuters, including claims for Reuters' failure since
February 1997 to pay any of the money due Cantor for data under this agreement.
In February 1997, Reuters unilaterally ceased making such payments to Cantor in
connection with the dispute and in November 1999 stopped distributing Cantor's
market data that was provided to Reuters.


                                       48
<PAGE>
     Reuters has recently asserted that, in the event it prevails in the
arbitration, it may be entitled to receive from Cantor, and possibly from us,
revenues in respect of the sale, license, dissemination, delivery or other
distribution of the data subject to this agreement. Reuters has also asserted
that, if it loses the arbitration, it could still, at the conclusion of the
arbitration, try to cure its multiple breaches and seek to have the agreement
remain in effect. Cantor believes that it did not materially breach this
agreement and believes that Reuters would not be entitled to (1) any of our
revenues, even if Reuters prevailed in the arbitration or (2) cure its own
breaches and cause the agreement to remain in effect, in the event Cantor
prevails. As stated above, Reuters ceased making payments under this agreement
in 1997 and has ceased distributing the data covered by the agreement. Cantor
has notified Reuters that Cantor has terminated the agreement based on Reuters'
material breaches.

     Market Data Corporation recently made an application for an order directing
(1) Reuters to pay Cantor for providing the data, (2) Cantor to continue to
provide Market Data Corporation with data for transmission to Reuters, and (3)
Reuters to accept and distribute the data over Reuters' network. That
application has been denied on the basis of Market Data Corporation's failure to
demonstrate that monetary damages would be an inadequate remedy for any damages
it may suffer as a result of Reuters' and Cantor's actions. Even if any relief
were granted to Market Data Corporation, we do not believe it would have a
material adverse effect on our business.

     Recently, the panel in the arbitration rendered a decision interpreting
certain portions of the agreement in a manner contrary to that which Cantor
believes was intended and concluded that Cantor had failed to deliver certain
non-screen, voice brokerage data to Reuters that the panel concluded was
required to be delivered under the agreement. Cantor maintains that it has not
materially breached the agreement, that any breach was cured by Cantor, that the
agreement cannot be terminated at Reuter's insistence, that Reuters has
underpaid Cantor and that, by ceasing to make payments since 1997 and
discontinuing the distribution of Cantor's data, Reuters has materially breached
the agreement. The panel has not resolved these issues and the arbitration is
still continuing.

     We cannot assure you that Market Data Corporation and/or Reuters will not
seek to assert claims against us or Cantor relating to our activities, either in
the arbitration or in another proceeding. In any event, Cantor has agreed to
indemnify us with respect to any claims asserted by Reuters or Market Data
Corporation relating to the agreement or arising out of the arbitration.

EMPLOYEES

     We have approximately 330 employees, five of whom are our executive
officers. None of these employees is represented by a union. We believe that we
have good relations with our employees.

PROPERTIES


     Our principal executive offices are located at One World Trade Center, New
York, New York. Our principal executive offices occupy approximately
50,000 square feet of leased space which we occupy pursuant to the
Administrative Services Agreement with Cantor. Our right to use this space
expires at the time that Cantor's lease expires in 2012. We will pay Cantor
approximately $1.2 million annually for use of this space. Our largest presence
outside of New York is in London, where we have the right to use approximately
15,000 square feet of Cantor's existing office space. Our right to use this
space expires at the earlier of (1) the time that Cantor's lease expires in 2016
or (2) when Cantor ceases to be an affiliate of ours and Cantor asks us to
vacate. We will pay Cantor approximately $800,000 annually for use of this
space. We believe our facilities are adequate for our reasonably foreseeable
future needs.

COMMITTEES OF THE BOARD

     In connection with the closing of this offering, we will establish (1) an
Audit Committee, all of the members of which will be non-employee directors, and
(2) a Compensation Committee.

     The Audit Committee will be responsible for recommending to the Board of
Directors the engagement of our independent auditors and reviewing with our
independent auditors the conduct and results of the audits, our internal
accounting controls, audit practices and the professional services furnished by
our independent auditors.

                                       51
<PAGE>
     The Compensation Committee will be responsible for reviewing and approving
all compensation agreements for our officers and for administering our stock
option plan and our stock purchase plan.

COMPENSATION OF DIRECTORS

     Directors who are also our employees will not receive additional
compensation for serving as directors. We expect to grant our initial
non-employee directors options to purchase 20,000 shares of our common stock at
an exercise price per share equal to the initial public offering price per
share. Any other options to be granted to non-employee directors will be in
amounts to be determined by our board of directors. Non-employee directors also
will be reimbursed for out-of-pocket expenses incurred in attending meetings of
our board of directors or committees of our board of directors.

EXECUTIVE COMPENSATION

     We are a recently formed company. Prior to March 1999, we did not conduct
any operations. As a result, we have not previously paid any compensation to our
Chief Executive Officer or other executive officers. We intend to pay or
allocate for payment to Messrs. Lutnick, Varacchi, Gardner, Piccoli and Merkel a
pro rata portion of their annual salaries of $350,000, $500,000, $250,000,
$125,000 and $150,000, respectively, for services they provide to us during
1999.

1999 LONG-TERM INCENTIVE PLAN

     In November 1999, our board of directors and stockholder approved our
adoption of our 1999 Long-Term Incentive Plan. The purpose of the plan is to
allow us to attract, retain and award present and prospective officers,
employees, directors, consultants and certain other individuals (including
employees of Cantor) and to compensate them in a way that provides additional
incentives and enables such individuals to increase their ownership interests in
our Class A common stock. Individual awards under the plan may take the form of:

     o either incentive stock options or non-qualified stock options;

     o stock appreciation rights;

     o restricted or deferred stock;

     o dividend equivalents;

     o bonus shares and awards in lieu of our obligations to pay cash
       compensation; and

     o other awards, the value of which is based in whole or in part upon the
       value of our Class A common stock.

     The plan will generally be administered by a committee, which will
initially be the Compensation Committee of our board, except that our board will
perform the committee's functions under the plan for purposes of grants of
awards to non-employee directors, and may perform any other function of the
committee as well. The committee generally is empowered to select the
individuals who will receive awards and the terms and conditions of those
awards, including the number of shares subject to the award exercise prices for
options and other exercisable awards, vesting and forfeiture conditions (if
any), performance conditions, the extent to which awards may be transferable and
periods during which awards will remain outstanding. Awards may be settled in
cash, shares, other awards or other property, as determined by the committee.

     The maximum number of shares of our Class A common stock that may be
subject to outstanding awards under the plan will not exceed 20% of the
aggregate number of shares of all classes of common stock outstanding determined
immediately after each award is granted. The number of shares deliverable upon
exercise of incentive stock options is limited to 10,000,000 shares of Class A
common stock.


     In connection with this offering, options in the form of non-qualified
stock options to purchase a total of 7,500,000 shares of Class A common stock
will be granted to our directors, executive officers and other employees as
follows: 20,000 shares to each of our three initial non-employee directors,
250,000 shares to Joseph Shea, 2,500,000 shares to Howard Lutnick, 800,000
shares to Frederick Varacchi, 375,000 shares to Douglas Gardner, 100,000 shares
to Stephen Merkel, 65,000 shares to Kevin Piccoli, 3,300,000 shares to our


                                       52
<PAGE>

other employees and other persons eligible to receive options under our plan and
300,000 shares to employees of Cantor. Each of the above options will have an
exercise price per share equal to the initial public offering price. Except as
to Mr. Lutnick, all options will be nontransferrable. As to Mr. Lutnick, 500,000
shares will be immediately exercisable and will be transferable to members of
his family (or a trust established for the benefit of his family) in order to
facilitate his estate planning. All options generally will be subject to vesting
requirements and will expire on the earlier of 10 years after the date of grant
or in connection with a termination of employment. However, Mr. Lutnick's
immediately exercisable option and the options granted to Cantor employees will
expire five years after the date of grant and generally will not terminate in
connection with a termination of employment. All options generally shall vest
and become exercisable upon a change in control of eSpeed, except that as to
Messrs. Varacchi, Gardner, Merkel, Piccoli, Shea and Lee Amaitis (the "Covered
Employees"), their options shall vest but continue to become exercisable in
accordance with their original vesting schedule (regardless of whether their
employment with eSpeed continues). However, if, following the change in control
of eSpeed, Mr. Lutnick at any time ceases to be eSpeed's chairman and chief
executive officer (other than by reason of his death or disability), all
then-unexercisable options held by the Covered Employees shall become fully
exercisable as of such date.


     The plan will remain in effect until terminated by our board. The plan may
be amended by our board without the consent of our stockholders, except that any
amendment, although effective when made, will be subject to stockholder approval
if required by any Federal or state law or regulation or by the rules of any
stock exchange or automated quotation system on which our common stock may then
be listed or quoted. The number of shares reserved or deliverable under the plan
and the number of shares subject to outstanding awards are subject to adjustment
in the event of stock splits, stock dividends and other extraordinary corporate
events.

     We generally will be entitled to a tax deduction equal to the amount of
compensation realized by a participant through awards under the plan, except (1)
no deduction is permitted in connection with incentive stock options if the
participant holds the shares acquired upon exercise for the required holding
periods; and (2) deductions for some awards could be limited under the
$1.0 million deductibility cap of Section 162(m) of the Internal Revenue Code.
This limitation, however, should not apply to awards granted under the plan
during a grace period of approximately three years following this offering, and
should not apply to certain options, stock appreciation rights and
performance-based awards granted thereafter if we comply with certain
requirements under Section 162(m).

STOCK PURCHASE PLAN

     In November 1999, our board of directors and stockholder approved the
adoption of our Stock Purchase Plan. The Stock Purchase Plan will permit our
eligible employees to purchase shares of our common stock at a discount.
Employees who elect to participate will have amounts withheld through payroll
deductions during purchase periods. At the end of each purchase period,
accumulated payroll deductions will be used to purchase stock at a price
determined by the administrative committee that administers the Stock Purchase
Plan, but which will not be less than 85% of the lower of the market price at
the beginning of the purchase period or the end of the purchase period,
including interim dates, as may be determined by the administrative committee.
Our Class A common stock that is purchased under the Stock Purchase Plan may be
subject to a holding period. We have reserved 425,000 shares of our Class A
common stock for issuance under the Stock Purchase Plan.

     The Stock Purchase Plan will remain in effect until terminated by our board
or until no shares of our Class A common stock are available for issuance under
the Stock Purchase Plan. The Stock Purchase Plan may be amended by our board
without the consent of our stockholders, except that any amendment, although
effective when made, will be subject to stockholder approval if required by any
federal or state law or regulation or by the rules of any stock exchange or
automated quotation system on which our common stock may then be listed or
quoted.

     The Stock Purchase Plan is intended to qualify under Section 423 of the
Internal Revenue Code, and as such, we will not be entitled to any tax deduction
where a participant holds the purchased shares for the longer of two years from
the beginning of the purchase period, or one year from the end of the purchase
period.

                            RELATIONSHIP WITH CANTOR
- --------------------------------------------------------------------------------

THE FORMATION TRANSACTIONS

     Concurrently with this offering, Cantor is contributing to us, and we are
acquiring from Cantor, substantially all of our assets. These assets primarily
consist of proprietary software, network distribution systems, technologies and
related contractual rights that comprise our eSPEED (SM) system. In exchange for
these assets, we are issuing to Cantor 43,999,900 shares of our Class B common
stock, representing approximately 98% of the voting power of our outstanding
capital stock after this offering. Cantor has elected to convert 2,500,000 of
these shares into shares of the Class A common stock which it is offering
hereby.

     Cantor conceived of and has been developing systems to promote fully
electronic marketplaces since the early 1990's. Since 1996, Cantor has invested
more than $200 million in information technology, which culminated in the
development of our eSPEED (SM) system. Cantor's technology initiatives during
this period included software development, infrastructure and maintenance
associated with operating Cantor's entire global securities business. The
evolutionary process which led to the development of the eSPEED (SM) system was
a combination of the development of Cantor's brokerage, trading, clearance,
settlement, analytical pricing and related systems and was impacted by the
continual improvement in computer processing and the changing trading
environment. Accordingly, it is difficult to separately quantify development or
other systems costs associated with the ultimate development of the eSPEED (SM)
system as it emanated in part from all of the information technology initiatives
of Cantor.

     Since January 1996, Cantor has used the eSPEED (SM) system internally to
conduct electronic trading. In March 1999, the first fully electronic
transaction using the eSPEED (SM) system was executed by a client.


     Cantor has previously entered into contractual agreements or other
arrangements with many of the participants that trade in our electronic
marketplaces. These agreements and arrangements provide the general terms and
conditions, including those relating to warranties and allocations of liability,
under which those participants may electronically execute trades in our
marketplaces; none of these participants are obligated to use our marketplaces
under these agreements. We either have, or will have upon the closing of this
offering, the rights and obligations under many of these agreements and
arrangements as they relate to operating our eSPEED (SM) system. Certain of our
subsidiaries have been registered as broker-dealers with the National
Association of Securities Dealers, Inc. and the regulatory authorities of
various states. We also intend to obtain any foreign regulatory approvals for
our foreign subsidiaries that are necessary or advisable. As we receive the
regulatory approvals and licenses necessary to operate our electronic
marketplaces globally and increase client awareness of our electronic
marketplaces, we intend to enter directly into tri-party agreements and other
arrangements with clients and Cantor. We assist market participants, including
Cantor, in participating in the electronic marketplaces that are created and
supported by our eSPEED (SM) system. We share with Cantor a portion of the
transaction-based revenues paid by market participants for transactions effected
through our electronic marketplaces or which are otherwise electronically
assisted. Cantor and many of the largest financial institutions in the world are
currently our primary clients.


     Following this offering, Cantor will continue to operate its equity dealing
business, money market and securities lending business, matched book repurchase
agreement business, investment advisory business and other specified businesses,
including those in which Cantor acts as a dealer. These businesses are carried
out in over 10 locations around the world. We will not share in any revenues
generated by these businesses, other than service fees we may become entitled to
receive in connection with hardware maintenance and other systems support
development services we may provide to Cantor. Following this offering, Cantor
will also continue to provide voice brokerage services, clearance, settlement
and fulfillment services and other related services in connection with our
electronic marketplaces. Accordingly, upon conversion of Cantor's marketplaces
to our eSpeed platform, orders for financial instruments will continue to be
received and executed by Cantor brokers over the telephone, and this method of
order entry by Cantor into our electronic trading platform is contemplated to
continue for the foreseeable future. It is anticipated that a significant
percentage of orders and revenues will continue to be recorded by Cantor, and a
sharing of commissions (as described below under "Joint Services Agreement")
with us will occur. Since it is not possible to predict the level of acceptance
by clients, and individual traders located within each client, of fully
electronic order entry

                                       54

processing, we anticipate that each marketplace product will experience widely
varying direct electronic usage rates by clients and their trading personnel.

     We entered into the agreements described below in connection with the
formation transactions and to help define the terms of our relationship with
Cantor in the future. In an effort to mitigate conflicts of interest between us
and Cantor, we and Cantor have agreed that none of these agreements may be
amended without the approval of a majority of our disinterested directors.

       ASSIGNMENT AND ASSUMPTION AGREEMENTS

     We have entered into Assignment and Assumption Agreements with Cantor
pursuant to which Cantor is contributing to us rights and interests in the
assets and contractual and other arrangements which comprise our eSPEED (SM)
system. In consideration for the contribution of these assets, rights and
interests, we will issue to Cantor shares of our Class B common stock
representing approximately 100% of the outstanding shares of our capital stock
prior to this offering and we will assume certain liabilities relating to the
assets which Cantor is contributing to us. These liabilities include accrued
compensation and benefits and other accrued liabilities. Under the terms of the
Assignment and Assumption Agreements, Cantor has agreed to indemnify us with
respect to liabilities and losses we suffer which result from the operation of,
and events relating to, the assets transferred to us prior to and in connection
with their transfer, except that we will assume the defense of and indemnify
Cantor with respect to any liabilities arising out of the patent litigation
involving Liberty Brokerage. We have agreed to indemnify Cantor with respect to
liabilities and losses which they suffer which result from our ownership and
operation of these assets.


       JOINT SERVICES AGREEMENT

     We have entered into a Joint Services Agreement with Cantor under which we
and Cantor have agreed to collaborate to provide brokerage and related services
to clients in multiple electronic markets for transactions in securities and
other financial products. In addition, we may in our discretion collaborate on
non-financial products. This agreement will be effective upon completing the
formation transactions and provides for a perpetual term. Under the agreement,
we will own and operate the electronic trading systems and will be responsible
for providing electronic brokerage services, and Cantor will provide
voice-assisted brokerage services, clearance, settlement and fulfillment
services and related services, such as credit and risk management services,
oversight of client suitability and regulatory compliance, sales positioning of
products and other services customary to brokerage operations.


     All information and data (other than information relating to bids, offers
or trades or other information that is input into, created by or otherwise
resides on an electronic trading system for financial products) created,
developed, used in connection with or relating to the operation of and effecting
of transactions in any marketplace will be the sole property of Cantor or us, as
applicable, on the following basis: (1) if the data relate to financial
products, the data belong solely to Cantor, (2) if the data relate to a
collaborative marketplace in which only products that are non-financial products
are traded, the ownership of the data will be determined by Cantor and us on a
case-by-case basis through good faith negotiations, (3) if the data relate to a
marketplace in which we do not collaborate with Cantor but in which we provide
electronic brokerage services and only non-financial products are traded, the
data belong solely to us and (4) if the data relate to a non-collaborative
marketplace that is not a marketplace in which we provide electronic brokerage
services and in which financial products are traded, the data belong solely to
Cantor. All right, title and interest in the data relating to bids, offers or
trades or other information that is input into, created by or otherwise resides
on an electronic trading system for financial products belong to Cantor. We have
the right to use such data only in connection with the execution of transactions
in such markets.

                Commission Sharing Arrangement

     Under this agreement, we and Cantor have agreed to share revenues derived
from transactions effected in the marketplaces in which we collaborate and other
specified markets. We have agreed to collaborate with Cantor to determine the
amount of commissions to be charged to clients that effect transactions in these
marketplaces; however, in the event we are unable to agree with Cantor with
respect to a transaction pricing decision, Cantor is entitled to make the final
pricing decision with respect to transactions for which Cantor provides
voice-assisted brokerage services and we are entitled to make the final pricing
decision with respect to transactions that are fully electronic. We may not make
a final transaction pricing decision that results in

                                       55
<PAGE>

the share of transaction revenues received by Cantor being less than Cantor's
actual cost of providing clearance, settlement and fulfillment services and
other transaction services. In some cases we will receive the aggregate
transaction revenues and pay a service fee to Cantor. In other cases Cantor will
receive the aggregate transaction revenues and pay a service fee to us. The
amount of the service fee and the portion of the transaction revenues that we
and Cantor receive is based on several factors, including whether: (1) the
marketplace is one in which we collaborate with Cantor; (2) the transaction is
fully electronic or Cantor provides voice-assisted brokerage services; (3) the
product traded is a financial product; and (4) the product is traded on the
CANTOR EXCHANGE (SM). Generally, we share revenues as follows:


          FULLY ELECTRONIC TRANSACTIONS IN COLLABORATIVE MARKETPLACES.  If a
     transaction is fully electronic and is effected in a marketplace in which
     we collaborate with Cantor, we will receive the aggregate transaction
     revenues and pay to Cantor a service fee equal to:

             o 35% of the transaction revenues, if the product is a financial
               product that is not traded on the CANTOR EXCHANGE (SM);

             o 20% of the transaction revenues, if the product is traded on the
               CANTOR EXCHANGE (SM); and

             o an amount determined on a case-by-case basis, if the product is
               not a financial product and is not traded on the CANTOR
               EXCHANGE (SM).

          VOICE-ASSISTED TRANSACTIONS IN COLLABORATIVE MARKETPLACES.  If Cantor
     provides voice-assisted brokerage services with respect to a transaction
     that is effected in a marketplace in which we collaborate with Cantor:

             o Cantor will receive the aggregate transaction revenues and pay to
               us a service fee equal to 7% of the transaction revenues, if the
               product is a financial product that is not traded on the CANTOR
               EXCHANGE (SM);

             o we will receive the aggregate transaction revenues and pay to
               Cantor a service fee equal to 55% of the transaction revenues, if
               the product is traded on the CANTOR EXCHANGE (SM); and

             o we will receive an amount determined on a case-by-case basis, if
               the product is not a financial product and is not traded on the
               CANTOR EXCHANGE (SM).

          NON-COLLABORATIVE MARKETPLACES INVOLVING ELECTRONIC BROKERAGE
     SERVICES.  If a transaction is effected in a marketplace in which we do not
     collaborate with Cantor:

             o Cantor will receive the aggregate transaction revenues and pay to
               us a service fee equal to 30% of the portion of the transaction
               revenues we would have received had we collaborated with Cantor,
               if Cantor either itself or through a third party provides
               electronic brokerage services in that marketplace;

             o we will receive the aggregate transaction revenues and pay to
               Cantor a service fee equal to 20% of the transaction revenues, if
               the product is a financial product and we provide electronic
               brokerage services; and

             o we will receive 100% of the transaction revenues and will not pay
               Cantor a service fee, if the product is not a financial product
               and we provide electronic brokerage service.

          ELECTRONICALLY ASSISTED TRANSACTIONS IN NON-ELECTRONIC
     MARKETPLACES.  If a transaction is not effected in an electronic
     marketplace, but is electronically assisted, such as a screen assisted open
     outcry transaction, we will receive 2.5% of the transaction revenues.

     In the event that Cantor's direct costs payable to third parties for
providing clearance, settlement and fulfillment services with respect to a
transaction in a collaborative marketplace with respect to any financial product
for any month exceed the direct costs incurred by Cantor to clear and settle a
cash transaction in United States Treasury securities for such month, the cost
of the excess is borne pro rata by Cantor and us in the same proportion as the
transaction revenues and service fees for such transaction are to be shared.

     In the event that a client does not pay, or pays only a portion of, the
transaction revenues relating to a transaction, then we and Cantor each bear our
respective share of the loss based on the percentage of the transaction revenues
we would otherwise have been entitled to receive with respect to such
transaction.

                                       56
<PAGE>
                System Services


     We have also agreed to provide to Cantor technology support services,
including (1) systems administration, (2) internal network support, (3) support
and procurement for desktops of end-user equipment, (4) operations and disaster
recovery services, (5) voice and data communications, (6) support and
development of systems for clearance, settlement and fulfillment services,
(7) systems support for Cantor brokers, (8) electronic applications systems and
network support and development for the unrelated dealer businesses with respect
to which we will not collaborate with Cantor and (9) provision and/or
implementation of existing electronic applications systems, including
improvements and upgrades thereto, and use of the related intellectual property
rights, having potential application in a gaming business. Cantor will pay to us
an amount equal to the direct and indirect costs, including overhead, that we
incur in performing these services. We will not receive service fees or
otherwise be entitled to share in transaction revenues relating to the system
services that we provide to Cantor for unrelated dealer businesses. We have
agreed not to use confidential information, including business plans and
software, obtained from or used by Cantor in connection with the provision of
these services to parties other than Cantor. For the purposes of the Joint
Services Agreement, an unrelated dealer business means (1) Cantor's equity
businesses as they exist from time to time, (2) Cantor's money market
instruments and securities lending division, as they exist from time to time,
(3) any business or portion thereof or activity in which Cantor acts as a dealer
or otherwise takes market risk or positions, including in the process of
executing matched principal transactions, providing the services of a specialist
or market maker or providing trading or arbitrage operations, (4) activities
wherever located that would, if conducted in the United Kingdom, be subject to
the United Kingdom Gaming Act of 1963 or activities wherever located currently
or in the future involving betting, gambling, odds making, lotteries, gaming,
wagering, staking, drawing or casting losts and similar or related activites and
(5) any business not involving operating a marketplace.


                Intellectual Property

     Cantor has granted to us a license covering Cantor's patents and patent
applications that relate to the eSPEED (SM) system. The license is perpetual,
irrevocable, world-wide and royalty free and is exclusive, except in the event
that (1) we are unwilling to provide to Cantor any requested services covered by
the patents with respect to a marketplace and Cantor elects not to require us to
do so, or we are unable to provide such services or (2) we do not exercise our
right of first refusal to provide to Cantor electronic brokerage services with
respect to a marketplace, in which events Cantor will have a limited right to
use the patents and patent applications solely in connection with the operation
of that marketplace. Cantor will cooperate with us, at our expense, in any
attempt by us to prevent any third party infringement of our patent rights under
the license.


     Cantor has also granted to us a non-exclusive, perpetual, irrevocable
worldwide, royalty-free right and license to use the trademarks "Cantor
Exchange," "Interactive Matching" and "CX".


                Non-competition and Market Opportunity Provisions

     The Joint Services Agreement imposes the following performance obligations
on us and restricts our ability to compete with Cantor and Cantor's ability to
compete with us in the following circumstances:

     o If Cantor wishes to create a new financial product marketplace, Cantor
       may require us to provide electronic brokerage services with respect to
       that marketplace. We must use our commercially reasonable efforts to
       develop an electronic trading system for that marketplace within a
       specified time period. If, after diligent effort, we are unable to do so,
       we have no liability to Cantor for our failure and Cantor may create and
       operate the marketplace in any manner that Cantor deems to be acceptable.
       Cantor's proposal to create a new marketplace must be commercially
       reasonable and Cantor must diligently pursue the development of the
       marketplace and cause the new marketplace to become operational within a
       specified time period.

     o If Cantor wishes to create a new financial product marketplace and Cantor
       does not require us to develop an electronic trading system for that
       marketplace as described in the preceding paragraph, Cantor must, in any
       event, notify us of its intention to create the new marketplace. We will
       have a right of first refusal to provide electronic brokerage services
       with respect to that marketplace. We must use commercially reasonable
       efforts to develop and put into operation an electronic trading system
       for the marketplace within a specified time period. If we are able to do
       so, transactions in the marketplace

                                       57
<PAGE>
       will be subject to the revenue sharing arrangements described above. If
       we are unable to do so, or we elect not to provide electronic brokerage
       services with respect to the new marketplace, Cantor may provide or
       otherwise obtain electronic brokerage services for that marketplace in
       any manner that Cantor deems to be acceptable. Cantor's proposal to
       create a new marketplace must be commercially reasonable and Cantor must
       diligently pursue the development of the marketplace and cause the new
       marketplace to become operational within a specified time period.

     o If Cantor wishes to create a new electronic marketplace for a product
       that is not a financial product, Cantor must notify us of its intention
       to do so. We will have the opportunity to offer to provide the electronic
       brokerage services with respect to the new marketplace. If Cantor rejects
       our offer, Cantor may operate the marketplace in any manner that Cantor
       deems to be acceptable.

     o If we wish to create a new electronic marketplace for a financial
       product, we must notify Cantor of our intention to do so. Cantor will
       have a right of first refusal to provide the applicable voice-assisted
       brokerage services, clearance, settlement and fulfillment services and/or
       related services for that marketplace. If Cantor (1) elects not to
       provide such services or (2) fails to notify us within a specified time
       period that it will provide such services, we may provide or otherwise
       obtain those services for that marketplace in any manner that we deem to
       be acceptable.

     o If we wish to create a new electronic marketplace for a product that is
       not a financial product, we must notify Cantor of our intention to do so.
       Cantor will have the opportunity to offer to provide the applicable
       voice-assisted brokerage services, clearance, settlement and fulfillment
       services and/or related services for that marketplace. If we reject
       Cantor's offer, we may create and operate the marketplace in any manner
       that we deem to be acceptable.

     o Subject to the exceptions described below, we may not directly or
       indirectly: (1) engage in any activities competitive with a business
       activity conducted by Cantor now or in the future; or (2) provide or
       assist any other person in providing voice-assisted brokerage services,
       clearance, settlement and fulfillment services and/or related services.
       We are permitted to engage in these activities:

          o in collaboration with Cantor;

          o with respect to a new marketplace involving a financial product,
            after Cantor has indicated that it is unable or unwilling to provide
            such voice-assisted brokerage services, clearance, settlement and
            fulfillment services and/or related services with respect to that
            marketplace;

          o with respect to a new marketplace involving a product that is not a
            financial product, after having considered in good faith any
            proposal submitted by Cantor relating to the provision of those
            services; or


          o with respect to an unrelated dealer business in which we develop and
            operate a fully electronic marketplace.


     o Subject to the exceptions described below, Cantor may not directly or
       indirectly provide or assist any other person in providing electronic
       brokerage services. Cantor is permitted to engage in these activities:

          o in collaboration with us;

          o with respect to a new marketplace, after (1) we have indicated that
            we are unable to develop an electronic trading system for that new
            marketplace within a specified time period or (2) we have declined
            to exercise our right of first refusal or have exercised our right
            of first refusal but are unable to develop an electronic trading
            system within a specified time period.

     o The unrelated dealer businesses retained by Cantor are expressly excluded
       from our rights of first refusal and the restrictions on Cantor's ability
       to compete with us. However, we may create fully electronic marketplaces
       in unrelated dealer businesses.

     We and Cantor are entitled to pursue and may enter into alliance
opportunities, including strategic alliances, joint ventures, partnerships or
similar arrangements, with third parties and consummate business combinations
with third parties on the following basis only. If an alliance opportunity (1)
relates to a person that directly or indirectly provides voice-assisted
brokerage services and engages in business operations that do not involve
electronic brokerage services, then Cantor is entitled to pursue and consummate
a transaction

                                       58
<PAGE>
with respect to that alliance opportunity, (2) relates to a person that directly
or indirectly provides electronic brokerage services and engages in business
operations that do not involve any voice-assisted brokerage service, then we are
entitled to pursue and consummate a transaction with respect to that alliance
opportunity or (3) is an alliance opportunity with respect to a person other
than those described in clauses (1) and (2) above, then we and Cantor will
cooperate to jointly pursue and consummate a transaction with respect to such
alliance opportunity on mutually agreeable terms. A business combination
includes a transaction initiated by and in which either we or Cantor is/are the
acquiror involving (A) a merger, consolidation, amalgamation or combination, (B)
any sale, dividend, split or other disposition of any capital stock or other
equity interests (or securities convertible into or exchangeable for or options
or warrants to purchase any capital stock or other equity equivalents) of the
person, (C) any tender offer (including without limitation of a self-tender),
exchange offer, recapitalization, dissolution or similar transaction, (D) any
sale, dividend or other disposition of a significant portion of the assets and
properties of the person (even if less than all or substantially all of such
assets or properties), and (E) entering into any agreement or understanding, or
the granting of any rights or options, with respect to any of the foregoing.

ADMINISTRATIVE SERVICES AGREEMENT

     We have entered into an Administrative Services Agreement with Cantor that
states the terms under which Cantor will provide certain administrative and
management services to us. Cantor will make available to us some of its
administrative and other staff, including its internal audit, treasury, legal,
tax, human resources, corporate development and accounting staffs. Members of
these staffs will arrange for our insurance coverage and will provide a wide
array of services, including administration of our personnel and payroll
operations, benefits administration, internal audits, facilities management,
promotional sales and marketing, legal, risk management, accounting and tax
preparation and other services. We will reimburse Cantor for the actual costs
incurred by Cantor, plus other reasonable costs, including reasonably allocated
overhead and any applicable taxes. We have also entered into arrangements with
Cantor under which we have the right to use certain assets, principally computer
equipment, from Cantor relating to the operation of our eSPEED (SM) system.
These assets are subject to operating leases with third party leasing companies.
Under this provision of the Administrative Services Agreement, we have agreed to
be bound by the general terms and conditions of the operating leases relating to
the assets used by us. See Note 5 of the Notes to the Consolidated Financial
Statements. Under the Administrative Services Agreement, we will provide sales,
marketing and public relations services to Cantor. Cantor will reimburse us for
the actual costs incurred by us, plus other reasonable costs, including
reasonably allocated overhead. The Administrative Services Agreement has a
three-year term which will renew automatically for successive one-year terms
unless canceled by either us or Cantor upon six months' prior notice; provided,
however, that our right to use our New York space expires at the time that
Cantor's lease expires in 2006 and our right to use our London office space
expires at the earlier of (1) the time Cantor's lease expires in 2016 or (2)
until Cantor ceases to be an affiliate of ours and Cantor asks us to vacate.

REGISTRATION RIGHTS AGREEMENT

     Pursuant to the Registration Rights Agreement to be entered into by Cantor
and us, Cantor is to receive piggyback and demand registration rights.

     The piggyback registration rights allow Cantor to register the shares of
Class A common stock issued or issuable to it in connection with the conversion
of its Class B common stock whenever we propose to register any shares of
Class A common stock for our own or another's account under the Securities Act
for a public offering, other than:

     o any shelf registration of shares of Class A common stock to be used as
       consideration for acquisitions of additional businesses; and

     o registrations relating to employee benefit plans.

     Cantor will also have the right, on three occasions, to require that we
register under the Securities Act any or all of the shares of Class A common
stock issued or issuable to it in connection with the conversion of its Class B
common stock. No more than one of these registrations may be demanded within the
first year after the closing of this offering. The demand and piggyback
registration rights apply to Cantor and to any transferee of shares held by
Cantor who agrees to be bound by the terms of the Registration Rights

                                       59
<PAGE>
Agreement. The ability of Cantor to exercise its registration rights for the
period of 180 days after this offering will be restricted by the lock-up
agreements described under "Shares Eligible for Future Sale."

     We have agreed to pay all costs of one demand and all piggyback
registrations, other than underwriting discounts and commissions. All of these
registration rights are subject to conditions and limitations, including
(1) the right of underwriters of an offering to limit the number of shares
included in that registration; (2) our right not to effect any demand
registration within six months of a public offering of our securities, including
this offering; and (3) that Cantor agrees to refrain from selling its shares
during the period from 15 days prior to and 90 days after the effective date of
any registration statement for the offering of our securities.

POTENTIAL CONFLICTS OF INTEREST AND COMPETITION WITH CANTOR

     Various conflicts of interest between us and Cantor may arise in the future
in a number of areas relating to our past and ongoing relationships, including
potential acquisitions of businesses or properties, the election of new
directors, payment of dividends, incurrence of indebtedness, tax matters,
financial commitments, marketing functions, indemnity arrangements, service
arrangements, issuances of our capital stock, sales or distributions by Cantor
of its shares of our common stock and the exercise by Cantor of control over our
management and affairs. A majority of our directors and officers following this
offering also serve as directors and/or officers of Cantor. Simultaneous service
as an eSpeed director or officer and service as a director or officer, or status
as a partner, of Cantor could create or appear to create potential conflicts of
interest when such directors, officers and/or partners are faced with decisions
that could have different implications for us and for Cantor. Mr. Lutnick, our
Chairman and Chief Executive Officer, is the sole stockholder of the managing
general partner of Cantor. As a result, Mr. Lutnick controls Cantor. Upon
completion of this offering, Cantor will own all of the outstanding shares of
our Class B common stock, representing approximately 98% of the combined voting
power of all classes of our voting stock. Mr. Lutnick's simultaneous service as
our Chairman and Chief Executive Officer and his control of Cantor could create
or appear to create potential conflicts of interest when Mr. Lutnick is faced
with decisions that could have different implications for us and for Cantor.

     Our relationship with Cantor may result in agreements that are not the
result of arm's length negotiations. As a result, the prices charged to us or by
us for services provided under agreements with Cantor may be higher or lower
than prices that may be charged by third parties and the terms of these
agreements may be more or less favorable to us than those that we could have
negotiated with third parties. However, we intend that transactions between us
and Cantor and/or its other affiliates will be subject to the approval of a
majority of our independent directors.

     In addition, Cantor can compete with us under certain circumstances. See
"--Joint Services Agreement--Non-competition Provisions."

CONSULTING SERVICES


     For consulting services provided to us and Cantor by Martin J. Wygod in
connection with this offering, we expect to issue to Martin J. Wygod or his
designees warrants to purchase an aggregate number of shares of our Class A
common stock equal to 1.5% of the aggregate number of shares of Class A common
stock offered by this prospectus (excluding any shares purchased pursuant to the
underwriters' over-allotment option). We anticipate that each of the warrants
will have a five-year term and will be exercisable commencing on the first
anniversary of the date of issuance at a price per share equal to the initial
public offering price. We expect that the warrants will not be transferable,
other than to charities and trusts established for the benefit of Mr. Wygod's
children and grandchildren.



     We intend to grant Mr. Wygod piggyback and demand registrations rights in
connection with the warrants. The piggyback registration rights will allow Mr.
Wygod to have registered the shares of Class A common stock issued or issuable
upon exercise of the warrants and will be substantially similar to the piggyback
registration rights to be granted to Cantor. Mr. Wygod will also have the right,
on one occasion, to require that we register under the Securities Act, a minimum
of 75% of the aggregate number of shares of Class A common stock underlying the
warrants. The demand registration right is only available when we are eligible
to use Form S-3 to register the shares.

(1) The address of each holder of more than five percent of our common stock
    listed above is One World Trade Center, New York, NY 10048.

(2) Unless otherwise indicated, we believe that the persons named in this table
    have sole voting and investment power with respect to the shares of common
    stock shown. The amounts and percentages are based upon 100 shares of common
    stock outstanding as of November 1, 1999. Shares of Class B common stock are
    convertible into shares of Class A common stock at any time in the
    discretion of the holder on a one-for-one basis. Accordingly, a holder of
    shares of Class B common stock is deemed to be the beneficial owner of an
    equal number of shares of Class A common stock for purposes of this table.

(3) Assumes no exercise of the underwriters' over-allotment option.

(4) Includes shares of Class B common stock that are owned by Cantor Fitzgerald
    Securities, of which Cantor Fitzgerald, L.P. is the managing partner. CF
    Group Management, Inc. is the Managing General Partner of Cantor Fitzgerald,
    L.P. and Mr. Lutnick is the President and sole stockholder of CF Group
    Management, Inc.

(5) Includes shares of Class B common stock that are owned by Cantor Fitzgerald
    Securities.

(6) Includes shares of Class B common stock owned of record by Cantor

     Cantor currently intends, at some point after the one-year period following
the completion of this offering, to distribute to its limited partners a portion
of the shares of Class B common stock owned by Cantor. In the event of any such
distribution, these shares would convert to shares of Class A common stock. The
terms on which such distribution, if any, may be made have not yet been
determined.

__________________________DESCRIPTION OF CAPITAL STOCK__________________________

GENERAL

     Following the completion of this offering, our authorized capital stock
will consist of 200,000,000 shares of Class A common stock, $.01 par value,
100,000,000 shares of Class B common stock, $.01 par value, and 50,000,000
shares of preferred stock, $.01 par value. Upon completion of this offering
(1) we will have 8,500,000 shares of Class A common stock and 41,500,000 shares
of Class B common stock outstanding; and (2) we will have outstanding options to
purchase 7,500,000 shares of Class A common stock.

     The following summary of the terms and provisions of our capital stock does
not purport to be complete. You should refer to our Amended and Restated
Certificate of Incorporation and our By-Laws, and to applicable law, for a
complete description of the terms and provisions of our capital stock.

COMMON STOCK

     The holders of Class A common stock and Class B common stock have identical
voting rights except that holders of Class A common stock are entitled to one
vote per share while holders of Class B common stock are entitled to 10 votes
per share on all matters to be voted on by stockholders. Holders of shares of
Class A common stock and Class B common stock are not entitled to cumulate their
votes in the election of directors. Generally, all matters to be voted on by
stockholders must be approved by a majority or, in the case of election of
directors, by a plurality of the votes entitled to be cast by holders of all
shares of Class A common stock and Class B common stock present in person or
represented by proxy, voting together as a single class, subject to any voting
rights granted to holders of any preferred stock. Amendments to our Amended and
Restated Certificate of Incorporation that would nevertheless change the powers,
preferences or special rights of the Class A common stock or the Class B common
stock so as to affect them adversely also must be approved by a majority of the
votes entitled to be cast by the holders of the shares affected by the
amendment, voting as a separate class. Any amendment to our Amended and Restated
Certificate of Incorporation to increase the authorized shares of any Class A
common stock will be deemed not to affect adversely the powers, preferences or
special rights of the Class A common stock. However, any amendment to our
Amended and Restated Certificate of Incorporation to increase the authorized
shares of Class B common stock or to amend, alter, change or repeal the rights
of Class B common stock must be approved by a majority of the voting power of
all of the outstanding shares of Class B common stock. The holders of Class A
common stock and Class B common stock are entitled to such dividends as may be
declared in the discretion of our board of directors out of legally available
funds, subject to the preferential dividend rights of any shares of preferred
stock. Holders of Class A common stock and Class B common stock have no
preemptive rights to purchase shares of our stock. Our Amended and Restated
Certificate of Incorporation provides that each share of Class B common stock is
convertible at any time, at the option of the holder, into one share of Class A
common stock. Each share of Class B common stock will automatically convert into
a share of Class A common stock upon any sale, pledge or other transfer (a
Transfer), whether or not for value, by the initial registered holder, other
than any Transfer by the initial holder to (1) Cantor Fitzgerald, L.P., (2) any
entity controlled by Cantor Fitzgerald, L.P. or by Howard Lutnick and (3) Howard
Lutnick, his spouse, his estate, any of his descendants, any of his relatives,
or any trust established for his benefit or for the benefit of his spouse, any
of his descendants or any of his relatives. Notwithstanding anything to the
contrary set forth herein, any holder of Class B common stock may pledge his,
her or its shares of Class B common stock to a pledgee pursuant to a bona fide
pledge of the shares as collateral security for indebtedness due to the pledgee
so long as the shares are not transferred to or registered in the name of the
pledgee. In the event of any pledge meeting these requirements, the pledged
shares will not be converted automatically into shares of Class A common stock.
If the pledged shares of Class B common stock become subject to any foreclosure,
realization or other similar action by the pledgee, they will be converted
automatically into shares of Class A common stock upon the occurrence of that
action. The automatic conversion provisions in our Amended and Restated
Certificate of Incorporation may not be amended, altered, changed or repealed
without the approval of the holders of a majority of the voting power of all
outstanding shares of Class A common stock.

     Shares of Class A common stock and Class B common stock are not subject to
any redemption provisions and shares of Class A common stock are not convertible
into any other securities. All outstanding

                                       62
<PAGE>
shares of Class A common stock and Class B common stock are fully paid and
nonassessable. The shares of our Class A common stock we will sell in this
offering will also be fully paid and nonassessable when we receive payment for
the shares.

PREFERRED STOCK

     Our Amended and Restated Certificate of Incorporation provides for
50,000,000 authorized shares of preferred stock, of which none are outstanding.
The existence of authorized but unissued preferred stock may enable our board of
directors to render more difficult or to discourage an attempt to obtain control
of us by means of a merger, tender offer, proxy contest or otherwise. For
example, if in the due exercise of its fiduciary obligations, our board of
directors were to determine that a takeover proposal is not in our best
interests, our board of directors could cause shares of preferred stock to be
issued without stockholder approval in one or more private offerings or other
transactions that might dilute the voting or other rights of the proposed
acquiror or insurgent stockholder group. In this regard, the Amended and
Restated Certificate of Incorporation grants our board of directors broad power
to establish the rights and preferences of authorized and unissued preferred
stock. The issuance of shares of preferred stock pursuant to our board of
directors' authority described above could decrease the amount of earnings and
assets available for distribution to holders of shares of common stock and
adversely affect the rights and powers, including voting rights, of these
holders and may have the effect of delaying, deterring or preventing a change in
control of our company. Our board of directors currently does not intend to seek
stockholder approval prior to any issuance of preferred stock, unless otherwise
required by law.

WARRANTS

     Upon completion of this offering, we expect to issue warrants representing
the right to acquire up to 127,500 shares of Class A common stock at the initial
public offering price per share. See "Relationship with Cantor--Consulting
Services."

LIMITATION ON DIRECTORS' LIABILITIES

     Our Amended and Restated Certificate of Incorporation limits, to the
maximum extent permitted under Delaware law, the personal liability of directors
and officers for monetary damages for breach of their fiduciary duties as
directors and officers, except in certain circumstances involving certain
wrongful acts, such as a breach of the director's duty of loyalty or acts of
omission which involve intentional misconduct or a knowing violation of law.

     Section 145 of the Delaware General Corporation Law permits us to indemnify
officers, directors or employees against expenses, including attorney's fees,
judgments, fines and amounts paid in settlement in connection with legal
proceedings if the officer, director or employee acted in good faith and in a
manner reasonably believed to be in or not opposed to our best interests and,
with respect to any criminal act or proceeding, if he or she had no reasonable
cause to believe his or her conduct was unlawful. Indemnification is not
permitted as to any matter as to which the person is adjudged to be liable
unless, and only to the extent that, the court in which such action or suit was
brought upon application determines that, despite the adjudication of liability,
but in view of all the circumstances of the case, the person is fairly and
reasonably entitled to indemnity for such expenses as the court deems proper.
Individuals who successfully defend such an action are entitled to
indemnification against expenses reasonably incurred in connection with the
action.

     Our Amended and Restated By-Laws require us to indemnify directors and
officers against, to the fullest extent permitted by law, liabilities which they
may incur under the circumstances described in the preceding paragraph.

     We plan to maintain standard policies of insurance under which coverage is
provided (1) to our directors and officers against loss arising from claims made
by reason of breach of duty or other wrongful act and (2) to us with respect to
payments which may be made by us to such officers and directors pursuant to the
above indemnification provision or otherwise as a matter of law.

                                       63

ANTI-TAKEOVER PROVISIONS

GENERAL

     Certain provisions of the Delaware General Corporation Law and our Amended
and Restated Certificate of Incorporation and our Amended and Restated By-Laws
may delay, discourage or prevent a change in control of our company unless the
takeover or change in control is approved by our board of directors. These
provisions also may render the removal of directors and management more
difficult. These provisions may discourage bids for our common stock at a
premium over the market price and may adversely affect the market price and
voting and other rights of the holders of our common stock.

CERTIFICATE OF INCORPORATION AND BY-LAWS

     Our Amended and Restated Certificate of Incorporation provides that
stockholders may act only at an annual or special meeting of stockholders and
may not act by written consent, other than by unanimous written consent. Our
Amended and Restated By-Laws provide that special meetings of stockholders may
be called only by the Chairman of our board of directors, or in the event the
Chairman of our board is unavailable, the Vice Chairman acting jointly with the
President. Our Amended and Restated By-Laws require advance written notice prior
to a meeting of stockholders of a proposal or director nomination which a
stockholder desires to present at such a meeting, which generally must be
received by our Secretary not later than 120 days prior to the first anniversary
of the date of our proxy statement for the preceding year's annual meeting. In
addition, our Amended and Restated Certificate of Incorporation permits us to
issue additional shares of Class B common stock or "blank check" preferred
stock.

     All amendments to our Amended and Restated By-Laws must be approved by
either the holders of a majority of the voting power of all outstanding capital
stock entitled to vote or by a majority of our board of directors.

     These provisions reduce our vulnerability to an unsolicited acquisition
proposal and discourage certain tactics that may be used in proxy fights.
However, these provisions could have the effect of discouraging others from
making tender offers for shares of our common stock and, as a consequence, they
also may inhibit fluctuations in the market price of our common stock that could
result from actual or rumored takeover attempts. These provisions also may have
the effect of preventing changes in our management.

DELAWARE ANTI-TAKEOVER LAW

     We are subject to Section 203 of the Delaware General Corporation Law. In
general, Section 203 prohibits a publicly held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years following the date the person became an interested
stockholder, unless the "business combination" or the transaction in which the
person became an "interested stockholder" is approved in a prescribed manner.
Generally, a "business combination" includes a merger, asset or stock sale or
other transaction resulting in a financial benefit to the "interested
stockholder." An "interested stockholder" is a person who, together with
affiliates and associates, owns 15% or more of a corporation's outstanding
voting stock, or was the owner of 15% or more of a corporation's outstanding
voting stock at any time within the prior three years, other than "interested
stockholders" prior to the time our common stock is quoted on Nasdaq. The
existence of this provision would be expected to have an anti-takeover effect
with respect to transactions not approved in advance by our board of directors,
including discouraging takeover attempts that might result in a premium over the
market price for the shares of our common stock held by stockholders.

TRANSFER AGENT AND REGISTRAR

     The Transfer Agent and Registrar for the common stock is American Stock
Transfer & Trust Company.

_________________________SHARES ELIGIBLE FOR FUTURE SALE________________________

     Upon completion of this offering, we will have 8,500,000 outstanding shares
of Class A common stock and 41,500,000 shares of Class B common stock. The
8,500,000 shares sold in this offering will be freely tradable without
restriction under the Securities Act except for any shares purchased by our
affiliates. The remaining 41,500,000 shares of Class B common stock held by
existing stockholders are "restricted securities" as that term is defined in
Rule 144.

     These restricted shares will become eligible for sale in the public market,
subject to the volume limitations under Rule 144 as described below, from time
to time following this offering, commencing in September 2000. All of these
restricted shares are subject to the contractual restrictions on sale described
below under the caption "Lock-up Agreements."

     Rule 144 makes available an exemption from the registration requirements of
the Securities Act. In general, under Rule 144, a person (or persons whose
shares are aggregated) who owns shares that were acquired from the issuer or an
affiliate of the issuer at least one year prior to the proposed sale will be
entitled to sell in any three-month period a number of shares that does not
exceed the greater of:

     o 1% of the then outstanding shares of the Class A common stock
       (approximately 85,000 shares immediately after this offering); or

     o the average weekly trading volume during the four calendar weeks
       preceding the date on which notice of the sale is filed with the
       Securities and Exchange Commission.

     Sales pursuant to Rule 144 are subject to certain requirements relating to
manner of sale, notice and availability of current public information about us.
A person (or persons whose shares are aggregated) who is not deemed to have been
an affiliate of ours at any time during the 90 days immediately preceding the
sale and who owns shares that were acquired from the issuer or an affiliate of
the issuer at least two years prior to the proposed sale is entitled to sell
such shares pursuant to Rule 144(k) without regard to the limitations described
above.

     There has been no public market for our Class A common stock prior to this
offering and no assurance can be given that an active public market for our
Class A common stock will develop or be sustained after completion of this
offering. Sales of substantial amounts of Class A common stock, or the
perception that these sales could occur, could adversely affect the prevailing
market price of our Class A common stock and could impair our ability to raise
capital or effect acquisitions through the issuance of our Class A common stock.

     We plan to register an additional 5,000,000 shares of our Class A common
stock under the Securities Act within 90 days after the closing of this offering
for use by us as consideration for future acquisitions. Upon registration, these
shares generally will be freely tradable after issuance, unless the resale
thereof is contractually restricted or unless the holders thereof are subject to
the restrictions on resale provided in Rule 145 under the Securities Act. Any
registered shares so issued will be subject to contractual restrictions that
will prevent the shares from being freely tradable during the 180 day period
after the date of this prospectus.

     After this offering, we intend to initially register 20% of the total
outstanding shares of our common stock, or approximately 10,000,000 shares of
Class A common stock, for issuance upon exercise of options granted under our
stock option plan. If we increase our total outstanding shares of common stock,
we will register additional shares of Class A common stock so that the stock
available for issuance under our stock option plan will be registered. We also
plan to register the 425,000 shares of Class A common stock issuable under our
stock purchase plan. Once we register the shares issuable under these plans,
they can be sold in the public market upon issuance, subject to restrictions
under the securities laws applicable to resales by affiliates.


     Cantor will have piggyback and demand registration rights to have
registered the shares of Class A common stock issued or issuable to it in
connection with the conversion of its Class B common stock and Martin Wygod will
have piggyback and demand registration rights to have registered the shares of
Class A common stock issued or issuable to him or his child's trust upon
exercise of the warrants to be granted to him and the trust by us. See
"Relationship with Cantor--Registration Rights Agreement" and "--Consulting
Services."


LOCK-UP AGREEMENTS

     We and our directors, executive officers and holders of our common stock
and securities convertible into or exercisable or exchangeable for common stock
issued prior to this offering or upon the consummation of the formation
transactions have agreed pursuant to certain "lock-up" agreements with the
underwriters that, subject to certain exceptions, we and they will not offer,
sell, contract to sell, pledge, grant any option to sell, or otherwise dispose
of, directly or indirectly, any shares of common stock or securities convertible
into or exercisable or exchangeable for common stock for a period of 180 days
after the date of this prospectus without the prior written consent of Warburg
Dillon Read LLC. Warburg Dillon Read LLC, in its sole discretion, may release
the shares subject to the lock-up agreements in whole or in part at any time
with or without notice. However, Warburg Dillon Read LLC has no current plan to
do so.

__________________________________UNDERWRITING__________________________________


     The selling stockholder and we have entered into an underwriting agreement
with the underwriters named below. Warburg Dillon Read LLC, Hambrecht and Quist
LLC and Thomas Weisel Partners LLC are acting as representatives of the
underwriters.


     The underwriting agreement provides for the purchase of a specific number
of shares of Class A common stock by each of the underwriters. The underwriters'
obligations are several, which means that each underwriter is required to
purchase a specified number of shares, but is not responsible for the commitment
of any other underwriter to purchase shares. Subject to the terms and conditions
of the underwriting agreement, each underwriter has severally agreed to purchase
the number of shares of Class A common stock set forth opposite its name below.

                                                                              ----------
</TABLE>

     This is a firm commitment underwriting. This means that the underwriters
have agreed to purchase all of the shares offered by this prospectus, other than
those covered by the over-allotment option described below, if any are
purchased. Under the underwriting agreement, if an underwriter defaults in its
commitment to purchase shares, the commitments of non-defaulting underwriters
may be increased or the underwriting agreement may be terminated, depending on
the circumstances.

     The representatives have advised us that the underwriters propose to offer
the shares directly to the public at the public offering price that appears on
the cover page of this prospectus. In addition, the representatives may offer
some of the shares to certain securities dealers at such price less a concession
of $       per share to certain other dealers. The underwriters may also allow
to dealers, and such dealers may reallow, a concession not in excess of $0.10
per share to certain other dealers. After the shares are released for sale to
the public, the representatives may change the offering price and other selling
terms at various times.

     We and the selling stockholder have granted the underwriters an
over-allotment option. This option, which is exercisable for up to 30 days after
the date of this prospectus, permits the underwriters to purchase a maximum of
1,275,000 additional shares of our Class A common stock to cover
over-allotments. If the underwriters exercise all or part of this option, they
will purchase shares covered by the option at the public offering price that
appears on the cover page of this prospectus, less the underwriting discount. If
this option is exercised in full, the underwriters will purchase 1,000,000
shares from us and 275,000 shares from the selling stockholder. To the extent
that the underwriters exercise the over-allotment option in part and not in
full, the underwriters will purchase shares from us and the selling stockholder
on a pro rata basis. If this option is exercised in full, the total price to the
public will be $176 million, the total proceeds to us will be approximately
$126 million and the total proceeds to the selling stockholder will be
$50 million, at an assumed offering price of $18 per share. The underwriters
have severally agreed that, to the extent the over-allotment option is
exercised, each of the underwriters will purchase a number of additional shares
proportionate to its initial amount reflected in the above table.

     We estimate that the total expenses of this offering, excluding the
underwriting discount, will be approximately $2,450,000.

     We and Cantor have agreed to indemnify the underwriters against specified
liabilities, including liabilities under the Securities Act.

     Thomas Weisel Partners LLC, one of the representatives of the underwriters,
was organized and registered as a broker-dealer in December 1998. Since December
1998, Thomas Weisel Partners has been named as a lead or co-manager on 87 filed
public offerings of equity securities, of which 64 have been completed, and has
acted as a syndicate member in an additional 45 public offerings of equity
securities. Thomas Weisel Partners does not have any material relationship with
us or any of our officers, directors or other controlling persons, except with
respect to its contractual relationship with us pursuant to the underwriting
agreement entered into in connection with this offering.

     We and our directors, executive officers and holders of our common stock
and securities convertible into or exercisable or exchangeable for common stock
issued prior to this offering, or upon consummation of the formation
transactions, have agreed pursuant to certain "lock-up" agreements with the
underwriters that, subject to certain exceptions, we and they will not offer,
sell, contract to sell, pledge, grant any option to sell, or otherwise dispose
of, directly or indirectly, any shares of common stock or securities convertible
into or exercisable or exchangeable for common stock for a period of 180 days
after the date of this prospectus without the prior written consent of Warburg
Dillon Read LLC. Warburg Dillon Read LLC, in its sole discretion, may release
the shares subject to the lock-up agreements in whole or in part at any time
with or without notice. However, Warburg Dillon Read LLC has no current plan to
do so.


     At our request, the underwriters have reserved for sale at the initial
public offering price up to 425,000 shares of our Class A common stock for our
officers, directors, employees, clients, friends and related persons who express
an interest in purchasing these shares. The number of shares of our Class A
common stock available for sale to the general public will be reduced to the
extent these persons purchase these reserved shares. The underwriters will offer
any shares not so purchased by these persons to the general public on the same
basis as the other shares in this initial public offering.



     Cantor Fitzgerald & Co., a subsidiary of the selling stockholder and an
indirect subsidiary of Cantor, is participating in this offering as an
underwriter. Consequently, this offering is being conducted in accordance with
Rule 2720 of the Conduct of Rules of the NASD, which provides that, among other
things, when an NASD member participates in the underwriting of its subsidiary's
equity securities, the initial public offering price can be no higher than that
recommended by a "qualified independent underwriter" meeting certain standards.
In accordance with this requirement, Warburg Dillon Read LLC is serving in this
role and will recommend a price in compliance with the requirements of
Rule 2720. In connection with this offering, Warburg Dillon Read LLC in its role
as qualified independent underwriter has performed due diligence investigations
and reviewed and participated in the preparation of this prospectus and the
registration statement of which this prospectus forms a part. In addition, the
underwriters may not confirm sales to any discretionary account without the
prior specific approval of the customer.


     Prior to this offering, there has been no public market for our Class A
common stock. Consequently, the offering price for our Class A common stock will
be determined by negotiations between us, the selling stockholder and the
underwriters and is not necessarily related to our asset value, net worth or
other established criteria of value. The factors considered in these
negotiations, in addition to prevailing market conditions, included the history
of and prospects for the industry in which we compete, an assessment of our
management, our prospects, our capital structure and certain other factors as
were deemed relevant.

     Rules of the Securities and Exchange Commission may limit the ability of
the underwriters to bid for or purchase shares before the distribution of the
shares is completed. However, the underwriters may engage in the following
activities in accordance with the rules:

     o Stabilizing transactions--The representatives may make bids for or
       purchases of the shares for the purpose of pegging, fixing or maintaining
       the price of the shares, so long as stabilizing bids do not exceed a
       specified maximum.

     o Over-allotments and syndicate covering transactions--The underwriters may
       create a short position in the shares by selling more shares than are set
       forth on the cover page of this prospectus. If a short position is
       created in connection with this offering, the representatives may engage
       in syndicate covering transactions by purchasing shares in the open
       market. The representatives may also elect to reduce any short position
       by exercising all or part of the over-allotment option.

     o Penalty bids--If the representatives purchase shares in the open market
       in a stabilizing transaction or syndicate covering transaction, they may
       reclaim a selling concession from the underwriters and selling group
       members who sold those shares as part of this offering.

     Stabilization and syndicate covering transactions may cause the price of
the shares to be higher than it would be in the absence of these transactions.
The imposition of a penalty bid might also have an effect on the price of the
shares if it discourages resales of the shares.

     Neither us nor the underwriters make any representation or prediction as to
the effect that the transactions described above may have on the price of the
shares. These transactions may occur on the Nasdaq National Market or otherwise.
If these transactions are commenced, they may be discontinued without notice at
any time.

     We and the underwriters expect that the shares will be ready for delivery
on the fourth business day following the date of this prospectus. Under
Securities and Exchange Commission regulations, secondary market trades are
required to settle in three business days following the trade date (commonly
referred to as "T+3"), unless the parties to the trade agree to a different
settlement cycle. As noted above, the shares will settle in T+3. Therefore,
purchasers who wish to trade on the date of this prospectus or during the next
three succeeding business days must specify an alternate settlement cycle at the
time of the trade to prevent a failed settlement. Purchasers of the shares who
wish to trade shares on the date of this prospectus or during the next three
succeeding business days should consult their own advisors.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors
and Stockholder of eSpeed, Inc.:

We have audited the accompanying consolidated statement of financial condition
of eSpeed, Inc. and Subsidiaries (the "Company") as of September 24, 1999, and
the related statements of operations, cash flows and changes in stockholder's
equity for the period from March 10, 1999 (date of commencement of operations)
to September 24, 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 audit.

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

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of the Company at September 24, 1999,
and the results of its operations and its cash flows for the period from
March 10, 1999 (date of commencement of operations) to September 24, 1999, in
conformity with generally accepted accounting principles.

(1) Pro forma income tax is computed as if the Company was subject to income tax
    as a corporation. As such, the tax benefit for state and local tax which is
    available to the Company as a division of CFS is no longer available as the
    Company would be in a net operating loss position.

                         eSPEED, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
    FOR THE PERIOD FROM MARCH 10, 1999 (DATE OF COMMENCEMENT OF OPERATIONS)
                              TO SEPTEMBER 24, 1999

1. ORGANIZATION AND FORMATION TRANSACTION

     eSpeed, Inc. (eSpeed or, together with its wholly owned subsidiaries, the
Company) is a wholly owned subsidiary of Cantor Fitzgerald Securities (CFS),
which in turn is a 99.5% owned subsidiary of Cantor Fitzgerald, L.P. (CFLP, or
together with CFS and its subsidiaries, Cantor). eSpeed commenced operations on
March 10, 1999 as a division of CFS. eSpeed is a Delaware corporation that was
formed on June 3, 1999. In September 1999, the Company's Board of Directors
changed eSpeed's fiscal year from the last Friday of March to December 31. The
Company engages in the business of operating interactive electronic marketplaces
designed to enable market participants to trade securities and other products
more efficiently and at a lower cost than traditional trading environments
permit.

     The Company filed a registration statement on Form S-1 with the Securities
and Exchange Commission for a public offering (the Offering) of Class A common
stock on September 21, 1999. The number of shares to be offered and the initial
offering price will be determined at a future date. On or prior to the effective
date of the Offering, and upon obtaining various regulatory approvals, the
formation transactions will be consummated and, as such, the accompanying
financial statements reflect such transactions and the activities of eSpeed
while operating as a division of CFS as the historical basis financial
statements of eSpeed. The formation transactions include an initial capital
contribution of net assets of $5,455,299. This contribution includes fixed
assets with a net book value of $7,370,560 and prepaid expenses of $1,202,223,
and the assumption of liabilities consisting of accrued compensation, accounts
payable and other liabilities of $3,117,484. In exchange for the contribution of
net assets, the Company issued Cantor 43,999,900 shares of Class B common stock.
Immediately thereafter, Cantor converted 2,500,000 shares of Class B common
stock to 2,500,000 shares of Class A common stock which will be sold in the
Offering.

     Upon completion of the Offering, the capitalization of eSpeed will consist
of 200,000,000 shares of authorized Class A common stock, $.01 par value,
100,000,000 shares of Class B common stock, $.01 par value, and 50,000,000
shares of preferred stock, $.01 par value. The rights of holders of shares of
common stock will be substantially identical, except that holders of Class B
common stock will be entitled to 10 votes per share, while holders of Class A
common stock will be entitled to one vote per share. Additionally, each share of
Class B common stock will be convertible at any time, at the option of the
holder, into one share of Class A common stock. Upon the completion of the
Offering, the Company expects to issue warrants for 127,500 shares of Class A
common stock. These warrants will have a five-year term and will be exercisable
commencing on the first anniversary of the date of issuance at a price per share
equal to the initial public offering price. These warrants will be dilutive in
nature.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     USE OF ESTIMATES--The preparation of the consolidated financial statements
in conformity with generally accepted accounting principles requires management
to make estimates and assumptions that affect the reported amounts of the assets
and liabilities, revenues and expenses, and the disclosure of contingent assets
and liabilities in the consolidated financial statements. Estimates, by their
nature, are based on judgment and available information. As such, actual results
could differ from the estimates included in these consolidated financial
statements.

     TRANSACTION REVENUES--Securities transactions and the related transaction
revenues are recorded on a trade date basis.

     FIXED ASSETS--Fixed assets, which comprise computer and communication
equipment and software, are depreciated over their estimated economic useful
lives of three to five years using an accelerated method. Upon commencement of
operations, the Company adopted Statement of Position 98-1, "Accounting for the
Costs of Computer Software Developed or Obtained for Internal Use." Accordingly,
internal and external

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
direct costs of application development and of obtaining software for internal
use are capitalized and amortized over their estimated economic useful lives of
three years on a straight line basis.

     NEW ACCOUNTING PRONOUNCEMENTS--In June 1998, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards ("SFAS")
No. 133, "Accounting for Derivative Instruments and Hedging Activities," which
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts, and for
hedging activities. The statement, as amended, is effective for fiscal years
beginning after June 15, 2000. eSpeed has evaluated the impact of adopting SFAS
No. 133 and believes it will not have a material effect on its financial
statements.

3. FIXED ASSETS

     Fixed assets consist of the following:

</TABLE>

4. INCOME TAXES

     The Company has operated as a division of CFS, which is a New York
partnership. Under applicable federal and state income tax laws, the taxable
income or loss of a partnership is allocated to each partner based upon their
ownership interest. CFS is, however, subject to the Unincorporated Business Tax
(UBT) of the City of New York, and the benefit for income taxes represents a
reduction in UBT. The loss generated by eSpeed will be used as a reduction of
the taxable income of CFS and, as such, eSpeed will be reimbursed for such tax
and has recognized the benefit as an offset to payable to affiliates. Upon
completion of the Offering, the stand-alone operations of eSpeed will be subject
to income tax as a corporation.

5. COMMITMENTS AND CONTINGENCIES

     LEASES--Under an administrative services agreement, eSpeed is obligated for
minimum rental payments under various non-cancelable leases with third parties,
principally for office space and computer equipment, expiring at various dates
through 2004 as follows:

5. COMMITMENTS AND CONTINGENCIES--(CONTINUED)
     LEGAL MATTERS--On May 5, 1999, Cantor, The Board of Trade of the City of
Chicago, The New York Mercantile Exchange and The Chicago Mercantile Exchange,
were sued by Electronic Trading Systems, Inc. in the United States District
Court for the Northern District of Texas (Dallas Division) for alleged
infringement of Wagner United States patent 4,903,201, entitled "Automated
Futures Trade Exchange." The patent relates to a system and method for
implementing an electronic, computer-automated futures exchange. On July 1,
1999, Cantor answered the complaint, asserting, among other things, that the
'201 patent was invalid and not infringed by Cantor and that Cantor was not the
real party in interest. Although not identified by the complaint, Cantor
believes that the system being charged with infringement is a version of the
electronic trading system used by the Cantor Exchange which Cantor is
contributing to the Company in connection with this offering. If the plaintiff
is successful in the lawsuit, the Company may be required to obtain a license to
develop and market one or more of its services, to cease developing or marketing
such services or to redesign such services. There can be no assurances that the
Company would be able to obtain such licenses or that the Company would be able
to obtain them at commercially reasonable rates, or if unable to obtain licenses
that the Company would be able to redesign its services to avoid infringement.


     Cantor owns U.S. patent 5,905,974, entitled "Automated Auction Protocol
Processor." On August 10, 1999, Liberty Brokerage Investment Corporation filed
an action for declaratory judgment in the United States District Court for the
District of Delaware against Cantor, claiming that the '974 patent was invalid,
unenforceable and not infringed by Liberty. On October 12, 1999, Cantor moved
(1) to dismiss all claims against Cantor for failure to state a claim upon which
relief can be granted and (2) to dismiss the action against Cantor for lack of
an actual case or controversy within the meaning of the law. On November 22,
1999, the Court granted the motion to dismiss the action as against Cantor
Fitzgerald Securities, and denied the motion to dismiss the action as against
Cantor and its affiliate CFPH, LLC. The Company cannot be assured that the
Company or Cantor will bring a claim for infringement of the '974 patent against
Liberty, that the '974 patent will be found to be valid and/or enforceable or
that Liberty will be found to have infringed the '974 patent. The Company will
assume responsibility for defending this suit on behalf of Cantor and its
affiliates.


     In February 1998, Market Data Corporation contracted with Chicago Board
Brokerage (a company controlled by the Chicago Board of Trade and Prebon Yamane)
to provide the technology for an electronic trading system to compete with
Cantor's United States Treasury brokerage business. Market Data Corporation is
controlled by Iris Cantor and Rodney Fisher, her nephew-in-law. Iris Cantor, a
company under the control of Iris Cantor referred to herein as CFI, and Rodney
Fisher are limited partners of Cantor Fitzgerald, L.P.

     In April 1998, Cantor Fitzgerald, L.P. filed a complaint in the Delaware
Court of Chancery against Market Data Corporation, Iris Cantor, CFI, Rodney
Fisher and Chicago Board Brokerage seeking an injunction and other remedies. The
complaint alleges that Iris Cantor, CFI and Rodney Fisher violated certain
duties, including fiduciary duties under Cantor's partnership agreement due to
their competition with Cantor Fitzgerald, L.P. with respect to the electronic
trading system mentioned above. The complaint further alleges that Market Data
Corporation and Chicago Board Brokerage tortiously interfered with Cantor's
partnership agreement and aided and abetted Iris Cantor's, CFI's and Rodney
Fisher's breaches of fiduciary duty. Iris Cantor, CFI and Rodney Fisher
counterclaimed seeking, among other things, (1) to reform agreements they have
with Cantor Fitzgerald, L.P. and (2) a declaration that Cantor Fitzgerald, L.P.
breached the implied covenant of good faith and fair dealing. Cantor has agreed
to indemnify the Company for any liabilities that the Company incurs with
respect to any current or future litigation involving (1) Market Data
Corporation, (2) Iris Cantor, (3) CFI or (4) Rodney Fisher.

     On July 12, 1998, the Court of Chancery held Cantor Fitzgerald, L.P. was
likely to succeed on the merits of its claims that Iris Cantor, CFI and Rodney
Fisher had breached their partnership obligations to

    FOR THE PERIOD FROM MARCH 10, 1999 (DATE OF COMMENCEMENT OF OPERATIONS)

Cantor but had not shown that the defendants' conduct was likely to cause
imminent irreparable harm between the date of the opinion and a final hearing.
The Court of Chancery, therefore, denied Cantor Fitzgerald, L.P.'s request for
preliminary injunctive relief and scheduled a final trial. Cantor Fitzgerald,
L.P. settled its dispute with Chicago Board Brokerage in April 1999 and Chicago
Board Brokerage subsequently announced it was disbanding its operations. The
remaining parties have completed the final trial and the Court of Chancery's
decision is expected following post-trial oral arguments scheduled for December
7, 1999. The Company believes Market Data Corporation's technology for
electronic trading systems will be of substantial assistance to competitors in
the wholesale market if provided to them.

     Two related actions are pending in New York. In a case pending in the
Supreme Court of New York, New York County, plaintiff Cantor Fitzgerald, L.P.
alleges, among other things, that defendants Market Data Corporation, CFI, Iris
Cantor and Rodney Fisher misused confidential information of Cantor Fitzgerald,
L.P. in connection with the above mentioned provision of technology to Chicago
Board Brokerage. In a case pending in the United States District Court for the
Southern District of New York, CFI and Iris Cantor allege, among other things,
that certain senior officers of Cantor Fitzgerald, L.P. breached fiduciary
duties they owed to CFI. The allegations in this lawsuit relate to several of
the same events underlying the court proceedings in Delaware. Neither of these
two cases has been pursued during the pendency of the court proceedings in
Delaware.

     In addition to the allegations set forth in the pending lawsuits, Cantor
has received correspondence from the attorneys representing Iris Cantor, CFI,
Market Data Corporation and Rodney Fisher in the proceedings in Delaware,
expressing a purported concern that Cantor and/or certain of its partners may be
in breach of Cantor's partnership agreement (including, among other things, the
partnership agreement's provisions relating to competition with the partnership)
and the general partnership agreement of Cantor Fitzgerald Securities with
respect to the Company's initial public offering. Generally, these attorneys
have alleged that various purported conflicts of interest will exist arising
from the fact that certain of the Company's directors and officers will
simultaneously hold positions with Cantor Fitzgerald, L.P. Moreover, these
attorneys have asserted that the Company's business plan may not be consistent
with certain purported rights of Market Data Corporation (including purported
intellectual property rights) and other parties and they have requested more
information regarding the Company's initial public offering.

     Although the Company does not expect to incur any losses with respect to
the pending lawsuits or supplemental allegations surrounding Cantor's
partnership agreement, Cantor has agreed to indemnify the Company with respect
to any liabilities the Company incurs as a result of such lawsuits or
allegations.

     Cantor and Reuters are parties to a confidential arbitration under the
auspices of the American Arbitration Association in New York, New York, which
began in June of 1995 with respect to a January 1993 agreement among Reuters,
Cantor and Market Data Corporation. Cantor has agreed to indemnify the Company
against all claims asserted by Reuters or Market Data Corporation relating to
this agreement or arising out of the arbitration.


     The agreement executed in 1993 involves, among other things, the delivery
by Cantor of certain market brokerage data arising out of non-United States
government bond and U.S. municipal bond interdealer brokerage transactions for
transmittal over Reuters' network. The agreement also contemplated the joint
development by Cantor and Reuters of an electronic trading system for certain
transactions in non-United States government bonds. Cantor and Reuters did not
develop this electronic trading system. In the arbitration, Reuters alleges that
Cantor materially breached the agreement primarily by failing to provide non-
screen, voice brokerage data concerning non-United States government bonds and
U.S. municipal bonds that Reuters contends are subject to the agreement and
fraud. Reuters is seeking to recover from Cantor amounts representing past
payments for market data, the reimbursement of attorneys' fees and other
damages. Cantor

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
    FOR THE PERIOD FROM MARCH 10, 1999 (DATE OF COMMENCEMENT OF OPERATIONS)
                             TO SEPTEMBER 24, 1999

5. COMMITMENTS AND CONTINGENCIES--(CONTINUED)


has denied Reuters' allegations that there has been any material breach of this
agreement or fraud, and has asserted a breach of contract claim and various
other counterclaims against Reuters, including claims for Reuters' failure since
February 1997 to pay any of the money due Cantor for data under this agreement.
In February 1997, Reuters unilaterally ceased making such payments to Cantor in
connection with the dispute and in November 1999 stopped distributing Cantor's
market data that was provided to Reuters.


     Reuters has recently asserted that, in the event it prevails in the
arbitration, it may be entitled to receive from Cantor, and possibly from the
Company, revenues in respect of the sale, license, dissemination, delivery or
other distribution of the data subject to this agreement. Reuters has also
asserted that, if it loses the arbitration, it could still, at the conclusion of
the arbitration, try to cure its multiple breaches and seek to have the
agreement remain in effect. Cantor believes that it did not materially breach
this agreement and believes that Reuters would not be entitled to (1) any of the
Company's revenues, even if Reuters prevailed in the arbitration or (2) cure its
own breaches and cause the agreement to remain in effect, in the event Cantor
prevails. As stated above, Reuters ceased making payments under this agreement
in 1997 and has ceased distributing the data covered by the agreement. Cantor
has notified Reuters that Cantor has terminated the agreement based on Reuters'
material breaches.

     Market Data Corporation recently made an application for an order directing
(1) Reuters to pay Cantor for providing the data, (2) Cantor to continue to
provide Market Data Corporation with data for transmission to Reuters, and (3)
Reuters to accept and distribute the data over Reuters' network. That
application has been denied on the basis of Market Data Corporation's failure to
demonstrate that monetary damages would be an inadequate remedy for any damages
it may suffer as a result of Reuters' and Cantor's actions. Even if any relief
were granted to Market Data Corporation, the Company does not believe it would
have a material adverse effect on its business.

     Recently, the panel in the arbitration rendered a decision interpreting
certain portions of the agreement in a manner contrary to that which Cantor
believes was intended and concluded that Cantor had failed to deliver certain
non-screen, voice brokerage data to Reuters that the panel concluded was
required under the agreement. Cantor maintains that it has not materially
breached the agreement, that any breach was cured by Cantor, that the agreement
cannot be terminated at Reuter's insistence, that Reuters has underpaid Cantor
and that, by ceasing to make payments since 1997 and discontinuing the
distribution of Cantor's data, Reuters has materially breached the agreement.
The panel has not resolved these issues and the arbitration is still continuing.

     The Company cannot give any assurance that Market Data Corporation and/or
Reuters will not seek to assert claims relating to the Company's activities
against the Company or Cantor, either in the arbitration or in another
proceeding. In any event, Cantor has agreed to indemnify the Company with
respect to any claims asserted by Reuters or Market Data Corporation relating to
the agreement or arising out of the arbitration.

     Although the ultimate outcome of these actions cannot be ascertained at
this time and the results of legal proceedings cannot be predicted with
certainty, it is the opinion of management that the resolution of these matters
will not have a material adverse effect on the financial condition or results of
operations of the Company.

     RISKS AND UNCERTAINTIES--The Company generates its revenues by providing
securities trading activities to, and by executing transactions with,
institutional customers of CFS and certain of its affiliates. Revenues for these
services are transaction based. As a result, the Company's revenues could vary
based on the transaction volume of financial markets around the world.

                             TO SEPTEMBER 24, 1999

6. RELATED PARTY TRANSACTIONS

     The Company operates interactive electronic marketplaces. For providing
these services, the Company receives a percentage of the transaction revenues
ranging from 2.5% to 100% from Cantor's marketplace businesses, depending on the
type of electronic services provided for the transaction. Revenues from such
transactions during the period ended September 24, 1999 totaled $15,034,597.

     On certain transactions (those where the Company receives 100% of the
commission revenue share), CFS or its affiliate provides the Company with
services for which CFS or its affiliate is paid a fee of 20% or 35% of the
transaction revenue earned on the transaction. Charges to the Company from CFS
and its affiliates for such transaction services during the period ended
September 24, 1999 totaled $1,337,282.

     The Company also provides network, data center and server administration
support and other technology services to CFS and its affiliates. The Company
charges CFS and its affiliates for these services commensurate with its costs of
providing these services. System services fees received from CFS and its
affiliates during the period ended September 24, 1999 totaled $9,104,872.

     Under an administrative services agreement, CFS and its affiliates provide
various administrative services to the Company, including accounting, tax, sales
and marketing, legal, and facilities management. The Company is required to
reimburse CFS or its affiliate for the cost of providing such services. The
costs represent the direct and indirect costs of providing such services and are
determined based upon the time incurred by the individual performing such
services. Management believes that this allocation methodology is reasonable.
The administrative services agreement has a three-year term which will renew
automatically for successive one-year terms unless cancelled upon six month's
prior notice by either the Company or CFS and its affiliates. The Company
incurred administrative fees for such services during the period ended
September 24, 1999 totaling $1,067,200.

7. REGULATORY CAPITAL REQUIREMENTS

     Through its broker-dealer subsidiaries, eSpeed Government Securities, Inc.
and eSpeed Securities, Inc., the Company will be subject to Securities and
Exchange Commission broker-dealer regulation under Section 15C and Rule 17a-5,
respectively, of the Securities Exchange Act of 1934. As such, at current
business levels these subsidiaries would be required to maintain minimum net
capital, as defined, of $25,000 and $5,000, respectively. In addition, eSpeed's
broker-dealer subsidiary in the United Kingdom, eSpeed Securities International
Limited, expects to be subject to the rules of the Securities and Futures
Authority, which requires minimum net capital of approximately $50,000.

8. EMPLOYEE BENEFIT PLAN

     Employees of eSpeed are eligible to participate in the Cantor Fitzgerald
Deferral Plan (the Plan), which is a deferred-salary plan sponsored by CFLP,
whereby an eligible employee may elect to defer a portion of his salary by
directing eSpeed to contribute to the Plan. The Plan is available to all
employees of eSpeed meeting certain eligibility requirements and is subject to
the provisions of the Employee Retirement Income Security Act of 1974. While the
Company has the option to contribute to the Plan on behalf of its participants,
no such contribution was made during the period ended September 24, 1999. The
administration of the Plan is performed by CFLP. The Company pays its
proportionate share of such administrative costs under the Administrative
Services Agreement.

9. LONG-TERM INCENTIVE PLAN

     The Company intends to adopt a Long-Term Incentive Plan (the Plan) which
will provide for awards in the form of 1) either incentive stock options or
non-qualified stock options (NQSOs); 2) stock appreciation rights;
3) restricted or deferred stock; 4) dividend equivalents; 5) bonus shares and
awards in lieu of

9. LONG-TERM INCENTIVE PLAN--(CONTINUED)
obligations to pay cash compensation; and 6) other awards the value of which is
based in whole or in part upon the value of eSpeed's common stock.

     The Compensation Committee of the Board of Directors will administer the
Plan and will generally be empowered to select the individuals who will receive
the awards and the terms and conditions of those awards.

     The Plan also authorizes the automatic grant of NQSOs to non-employee
directors upon initial election as a director and additional grants at each
annual meeting thereafter. These options will have an exercise price equal to
the fair market value of the Class A common stock on the date of grant.


     In connection with the Offering, the Company also intends to issue
7,200,000 stock options to certain officers, directors and employees at an
exercise price equal to the initial public offering price. Additionally, the
Company anticipates granting approximately 300,000 stock options to certain
employees of Cantor at an exercise price equal to the initial public offering
price. This will result in an estimated, one time non-cash charge to the Company
of $4,000,000.


10. STOCK PURCHASE PLAN


     The Company intends to adopt a Stock Purchase Plan to permit eligible
employees, including employees of Cantor, to purchase shares of eSpeed common
stock at a discount. At the end of each purchase period, as defined, accumulated
payroll deductions will be used to purchase stock at a price determined by a
Stock Purchase Plan administrative committee, which will generally not be less
than 85% of the lowest market price at various defined dates during the purchase
period. The Company has reserved 425,000 shares of Class A common stock for
issuance under the Stock Purchase Plan.


11. SEGMENT AND GEOGRAPHIC DATA

     SEGMENT INFORMATION--The Company currently operates its business in one
segment, that of operating interactive electronic marketplaces for the trading
of securities and other financial products. This segment comprised approximately
62% of revenues for the period ended September 24, 1999. The remainder of the
Company's revenues were derived from system services fees received from CFS and
its affiliates.

     GEOGRAPHIC INFORMATION--The Company operates in the U.S., Europe and Asia.
Revenue attribution for purposes of preparing geographic data is principally
based upon the marketplace where the financial product is traded, which, as a
result of regulatory jurisdiction constraints in most circumstances, is also
representative of the location of the client generating the transaction
resulting in commissionable revenue. The information

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Our By-Laws provide that we shall, to the fullest extent permitted by
Section 145 of the General Corporation Law of the State of Delaware (the
"DGCL"), as amended from time to time, indemnify all persons whom it may
indemnify pursuant thereto.

     Section 145 of the DGCL permits a corporation, under specified
circumstances, to indemnify its directors, officers, employees or agents against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlements actually and reasonably incurred by them in connection with any
action, suit or proceeding brought by third parties by reason of the fact that
they were or are directors, officers, employees or agents of the corporation, if
such directors, officers, employees or agents acted in good faith and in a
manner they reasonably believed to be in or not opposed to the best interests of
the corporation and, with respect to any criminal action or proceeding, had no
reason to believe their conduct was unlawful. In a derivative action, i.e., one
by or in the right of the corporation, indemnification may be made only for
expenses actually and reasonably incurred by directors, officers, employees or
agents in connection with the defense or settlement of an action or suit, and
only with respect to a matter as to which they shall have acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation, except that no indemnification shall be made if
such person shall have been adjudged liable to the corporation, unless and only
to the extent that the court in which the action or suit was brought shall
determine upon application that the defendant directors, officers, employees or
agents are fairly and reasonably entitled to indemnity for such expenses despite
such adjudication of liability.

     Our Amended and Restated Certificate of Incorporation provides that our
directors will not be personally liable to us or our stockholders for monetary
damages resulting from breaches of their fiduciary duty as directors except (a)
for any breach of the duty of loyalty to us or our stockholders, (b) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (c) under Section 174 of the DGCL, which makes directors
liable for unlawful dividends or unlawful stock repurchases or redemptions, or
(d) for transactions from which directors derive improper personal benefit.

     The Underwriting Agreement, filed as Exhibit 1, provides that the
Underwriters named therein will indemnify us and hold us harmless and each of
our directors, officers or controlling persons from and against certain
liabilities, including liabilities under the Securities Act. The Underwriting
Agreement also provides that such Underwriters will contribute to certain
liabilities of such persons under the Securities Act.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

     On September 7, 1999, we issued 100 shares of common stock to Cantor
Fitzgerald Securities for an aggregate purchase price of $200,000.

     The sale of the above securities was deemed to be exempt from registration
under the Securities Act in reliance on Section 4(2) of the Securities Act, or
Regulation D promulgated thereunder, as a transaction by an issuer not involving
a public offering.

ITEM 17. UNDERTAKINGS.

     The undesigned registrant hereby undertakes as follows:

          (1) The undersigned will 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.

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

          (3) 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 the offering of such securities at that
     time shall be deemed to the initial bona fide offering thereof.

     Insofar as indemnification arising under the Securities Act may be
permitted to directors, officers and controlling persons of the registrant
pursuant to the provisions described in Item 14 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 its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

c/o   Warburg Dillon Read LLC
      299 Park Avenue
      New York, New York  10171-0026


Ladies and Gentlemen:

     eSpeed, Inc., a Delaware corporation (the "Company") and an indirect
subsidiary of Cantor Fitzgerald, L.P., a Delaware limited partnership (the
"Parent"), proposes to issue and sell to the underwriters named in Schedule A
annexed hereto (the "Underwriters") an aggregate of 6,000,000 shares (the "Firm
Shares") of its Class A Common Stock, $.01 par value (the "Common Stock"), and
Cantor Fitzgerald Securities, a New York partnership (the "Selling Stockholder")
and a subsidiary of the Parent, proposes to sell to the Underwriters 2,500,000
shares of Common Stock. In addition, solely for the purpose of covering
over-allotments, the Company and the Selling Stockholder propose to grant to the
Underwriters the option to purchase from the Company and the Selling Stockholder
up to an additional 1,275,000 shares of Common Stock in the aggregate (the
"Additional Shares" and, collectively with the Firm Shares, the "Shares"). Of
the Additional Shares, up to 1,000,000 Shares may be sold by the Company and up
to 275,000 Shares may be sold by the Selling Stockholder. The Shares are
described in the Prospectus as defined below.

     The Company has filed, in accordance with the provisions of the Securities
Act of 1933, as amended, and the rules and regulations thereunder (collectively
called the "Act"), with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-1 (Reg. No. 333-87475)
including a prospectus, relating to the Shares. The Company has furnished to
you, for use by the Underwriters and by dealers, copies of one or more
preliminary prospectuses (each thereof being herein called a "Preliminary
Prospectus") relating to the Shares. Except where the context otherwise
requires, the registration statement, as amended when it becomes effective,
including all documents filed as a part thereof, and


                                       1
<PAGE>

including any information contained in a prospectus subsequently filed with the
Commission pursuant to Rule 424(b) under the Act and deemed to be part of the
registration statement at the time of effectiveness pursuant to Rule 430(A)
under the Act and also including any registration statement filed pursuant to
Rule 462(b) under the Act, is herein called the "Registration Statement", and
the prospectus, in the form filed by the Company with the Commission pursuant to
Rule 424(b) under the Act on or before the second business day after the date
hereof (or such earlier time as may be required under the Act) or, if no such
filing is required, the form of final prospectus included in the Registration
Statement at the time it became effective, is herein called the "Prospectus".

     The Company, the Selling Stockholder, the Parent and the Underwriters agree
as follows:

     1. Sale and Purchase. Upon the basis of the warranties, representations and
covenants, and subject to the terms and conditions herein set forth, the Company
agrees to sell to the respective Underwriters and each of the Underwriters,
severally and not jointly, agrees to purchase from the Company that number of
Firm Shares which bears the same proportion to the aggregate number of Firm
Shares to be issued and sold by the Company as the number of Firm Shares set
forth opposite the name of such Underwriter in Schedule A annexed hereto bears
to the aggregate number of Firm Shares to be sold by the Company and the Selling
Stockholder. In addition, upon the basis of the warranties, representations and
covenants and subject to the terms and conditions herein set forth, the Selling
Stockholder agrees to sell to the respective Underwriters and each of the
Underwriters, severally and not jointly, agrees to purchase from the Selling
Stockholder that number of Firm Shares which bears the same proportion to the
aggregate number of Firm Shares to be sold by the Selling Stockholder as the
number of Firm Shares set forth opposite the name of such Underwriter in
Schedule A annexed hereto bears to the aggregate number of Firm Shares to be
sold by the Company and the Selling Stockholder. The purchase price in respect
of the Shares to be purchased by the Underwriters from the Company and the
Selling Stockholder shall be $            per Share. The Company and the Selling
Stockholder are advised by you that the Underwriters intend (i) to make a public
offering of their respective portions of the Firm Shares as soon after the
effective date of the Registration Statement as in your judgment is advisable
and (ii) initially to offer the Firm Shares upon the terms set forth in the
Prospectus. You may from time to time increase or decrease the public offering
price after the initial public offering to such extent as you may determine.

     Upon the basis of the warranties, representations and covenants, and
subject to the terms and conditions herein set forth, the Company and the
Selling Stockholder also hereby grant to the several Underwriters the option to
purchase, and the Underwriters shall have the right to purchase, severally and
not jointly, from the Company and the Selling Stockholder, ratably in accordance
with the number of Firm Shares to be purchased by each of

                                       2
<PAGE>

them, all or a portion of the Additional Shares as may be necessary to cover
over-allotments made in connection with the offering of the Firm Shares, at the
same purchase price per share to be paid by the Underwriters to the Company and
the Selling Stockholder for the Firm Shares. This option may be exercised by you
on behalf of the several Underwriters at any time (but not more than once) on or
before the thirtieth day following the date hereof, by written notice to the
Company and the Selling Stockholder. Such notice shall set forth the aggregate
number of Additional Shares as to which the option is being exercised, and the
date and time when the Additional Shares are to be delivered (such date and time
being herein referred to as the additional time of purchase); provided, however,
that the additional time of purchase shall not be earlier than the time of
purchase (as defined below) nor earlier than the second business day1 after the
date on which the option shall have been exercised nor later than the tenth
business day after the date on which the option shall have been exercised. To
the extent that the option is exercised in part, Additional Shares shall be sold
by the Company and the Selling Stockholder pro rata. The aggregate number of
Additional Shares to be sold to each Underwriter shall be the number which bears
the same proportion to the aggregate number of Additional Shares being purchased
as the number of Firm Shares set forth opposite the name of such Underwriter on
Schedule A hereto bears to the total number of Firm Shares (subject, in each

     agreement or other agreement or instrument to which the Company, the Parent
     or the Selling Stockholder or any of their respective subsidiaries is a
     party or by which any of them or their respective properties may be bound
     or affected and which is known to such counsel or under any federal, state,
     local or foreign law, regulation or rule or any decree, judgment or order
     known by such counsel to be applicable to the Company, the Parent or the
     Selling Stockholder or any of their respective subsidiaries, except in all
     such cases with respect to clauses (a) and (b) as would not, individually
     or in the aggregate, reasonably be expected to have a Material Adverse
     Effect;

         (v) to such counsel's knowledge, there are no actions, suits, claims,
     investigations or proceedings pending or, to such counsel's knowledge,
     threatened to which the Parent or the Selling Stockholder or any of their
     respective subsidiaries is subject or of which any of their respective
     properties is subject at law or in equity or before or by any federal,
     state, local or foreign governmental or regulatory commission, board, body,
     authority or agency which are required to be described in the Prospectus
     but are not so described as required;

         (vi) each of the Assignment and Assumption Agreements, the Joint
     Services Agreement and the Administrative Services Agreement has been duly
     authorized, executed and delivered by the Company, the Parent and each
     other party thereto and constitutes a legal, valid and binding agreement of
     the Company, the Parent and each other party thereto enforceable in
     accordance with its terms, subject to the qualification that the
     enforceability of the obligations of the Company, the Parent and each other
     party thereto thereunder may be limited by bankruptcy, insolvency,
     reorganization, moratorium and other laws relating to or affecting
     creditors' rights generally and by general equitable principles; none of
     the execution, delivery and performance of the Assignment and Assumption
     Agreements, the Joint Services Agreement and the Administrative Services
     Agreement, the consummation of the transactions contemplated thereby or the
     contribution to and the acquisition by the Company of assets as described
     in the Prospectus under the caption "Relationship with Cantor -- The
     Formation Transactions," constitutes or will result in a Default Event
     under any provisions of the charter or by-laws of the Company, the Parent
     or any other party thereto or any of their respective subsidiaries or under
     any provision of any license, permit, indenture, mortgage, deed of trust,
     bank loan or credit agreement or other evidence of indebtedness, or any
     lease, contract or other agreement or instrument to which the Company, the
     Parent or any other party thereto or any of their respective subsidiaries
     is a party or by which any of them or their respective properties may be
     bound or

                                       26

     affected and which is known to such counsel or under any federal, state,
     local or foreign law, regulation or rule or any decree, judgment or order
     known by such counsel to be applicable to the Company, the Parent or any
     other party thereto or any of their respective subsidiaries, other than
     such Default Events that would not individually or in the aggregate
     reasonably be expected to have a Material Adverse Effect;

         (vii) such counsel has read the statements in the Prospectus under the
     captions "Risk Factors -- Risks Related to Our Business -- If Cantor or we
     are unable to protect the intellectual property rights we license from
     Cantor, our ability to operate electronic trading marketplaces may be
     materially adversely affected", "Risk Factors -- Risks Related to Our
     Business -- If it becomes necessary to protect or defend our intellectual
     property rights, we may have to resort to costly litigation", "Risk
     Factors -- Risks Related to Our Business -- If our software licenses from
     third parties are terminated, our ability to operate our business may be
     materially adversely affected", "Risk Factors -- Risks Related to Our
     Business -- If the strength of our domain names is diluted, the value of
     our proprietary rights may decrease", "Risk Factors -- Risks Related to Our
     Business -- If we infringe on patent rights or copyrights of others, we
     could become involved in costly litigation", "Business Our Intellectual
     Property", "Business -- Regulation", "Business -- Legal Proceedings" and
     "Relationship with Cantor" and insofar as such statements constitute
     summaries of legal matters, contracts, agreements, documents or proceedings
     referred to therein, or refer to statements of law or legal conclusions,
     such statements are accurate in all material respects and fairly present
     the information purported to be shown;

         (viii) the Selling Stockholder has full legal right and authority to
     sell, transfer and deliver in the manner provided in this Agreement the
     Shares being sold by the Selling Stockholder hereunder; and

         (ix) delivery by the Selling Stockholder to the several Underwriters of
     certificates for the Shares being sold hereunder by the Selling
     Stockholder, against payment therefor as provided herein, assuming each of
     the Underwriters has purchased the Selling Stockholder's shares in good
     faith and without notice of any adverse claim, will pass good and
     marketable title to such Shares to the several Underwriters, free and clear
     of all liens, encumbrances and defects.

         In addition, such counsel shall state that such counsel has
participated in conferences with officers and other representatives of the
Company and the Parent,

                                       27
<PAGE>

representatives of the independent public accountants of the Company and
representatives of the Underwriters at which the contents of the Registration
Statement and Prospectus were discussed and, although such counsel is not
passing upon and does not assume responsibility for the accuracy, completeness
or fairness of the statements contained in the Registration Statement or
Prospectus (except as and to the extent stated in subparagraph (vii) above), on
the basis of the foregoing nothing has come to the attention of such counsel
that causes such counsel to believe that the Registration Statement or any
amendment thereto at the time such Registration Statement or amendment became
effective contained an untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or that the Prospectus or any supplement thereto at the
date of such Prospectus or such supplement, and at all times up to and including
the time of purchase or additional time of purchase, as the case may be,
contained an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading (it
being understood that such counsel need express no belief with respect to the
financial statements and schedules and other financial, statistical and
accounting data included in the Registration Statement or Prospectus).

         (c) You shall have received at the time of purchase and at the
additional time of purchase, as the case may be, the opinion of Norton Rose,
special international counsel to the Company, dated the time of purchase or the
additional time of purchase, as the case may be, stating that:

         (i) eSpeed Securities International Limited has been duly incorporated
     and is validly existing as a corporation in good standing under the laws of
     England and Wales, with the requisite corporate power and authority to own,
     lease and operate its respective properties and to conduct its respective
     business; and all of the outstanding shares of capital stock of eSpeed
     Securities International Limited have been duly authorized and validly
     issued and are fully paid and non-assessable and, to the knowledge of such
     counsel, are owned by the Company;

         (ii) eSpeed Securities International Limited is duly qualified to do
     business as a foreign corporation in good standing in ;

         (iii) the execution, delivery and performance of this Agreement by the
     Company and the consummation by the Company of the transactions
     contemplated hereby do not constitute, and will not result in, a Default
     Event

                                       28
<PAGE>

     under any provisions of the articles and memorandum of association of
     eSpeed Securities International Limited;

         (iv) each of the Assignment and Assumption Agreement (international
     version), the Joint Services Agreement and the Administrative Services
     Agreement has been duly authorized, executed and delivered by eSpeed
     Securities International Limited and constitutes a legal, valid and binding
     agreement of eSpeed Securities International Limited enforceable in
     accordance with its terms, subject to the qualification that the
     enforceability of the obligations of eSpeed Securities International
     Limited thereunder may be limited by bankruptcy, insolvency,
     reorganization, moratorium and other laws relating to or affecting
     creditors' rights generally and by general equitable principles; and none
     of the execution, delivery and performance of the Assignment and Assumption
     Agreements, the Joint Services Agreement and the Administrative Services
     Agreement, the consummation of the transactions contemplated thereby or the
     contribution to and the acquisition by the Company and its Subsidiaries of
     assets as described in the Prospectus under the caption "Relationship with
     Cantor -- The Formation Transactions," constitutes or will result in a
     Default Event under any provisions of the charter or by-laws of eSpeed
     Securities International Limited; and

         (v) nothing has come to such counsel's attention that causes them to
     believe that the statements with respect to regulatory matters (solely
     insofar as such statements pertain to England and Wales) included in the
     Prospectus, as of its date and as of the date of such opinion, contained or
     contains an untrue statement of material fact or omitted or omits to state
     a material fact required to be stated therein or necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading.

         (d) You shall have received from Deloitte & Touche LLP letters dated,
respectively, the date of this Agreement and the time of purchase and additional
time of purchase, as the case may be, and addressed to the Underwriters (with

         (e) You shall have received at the time of purchase and at the
additional time of purchase, as the case may be, the opinion of Dewey Ballantine
LLP, counsel for the Underwriters, dated the time of purchase or the additional
time of purchase, as the case may be, with respect to the issuance and sale of
the Shares by the Company, the Registration Statement, the Prospectus (together
with any supplement thereto) and other related matters as the Underwriters may
require.

                                       29

         (f) No amendment or supplement to the Registration Statement or
Prospectus shall at any time have been filed to which you have objected or shall
object in writing.

         (g) The Registration Statement shall have become effective, at or
before 5:30 P.M., New York City time, on the date of this Agreement, unless a
later time shall be agreed to by the Company and you in writing or by telephone,
confirmed in writing, and, if Rule 430A under the Act is used, the Prospectus
shall have been filed with the Commission no later than 5:30 P.M., New York City
time, on the second full business day after the date of this Agreement;
provided, however, that the Company and you and any group of Underwriters,
including you, who have agreed hereunder to purchase in the aggregate at least
50% of the Firm Shares may from time to time agree on a later date.

         (h) Prior to the time of purchase or the additional time of purchase,
as the case may be, (i) no stop order with respect to the effectiveness of the
Registration Statement shall have been issued under the Act or proceedings
initiated under Section 8(d) or 8(e) of the Act; (ii) the Registration Statement
and all amendments thereto, or modifications thereof, if any, shall not contain
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein not misleading;
and (iii) the Prospectus and all amendments or supplements thereto, or
modifications thereof, if any, shall not contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they are made, not misleading.

         (i) Between the time of execution of this Agreement and the time of
purchase or the additional time of purchase, as the case may be, (i) no material
and adverse change, financial or otherwise (other than as referred to in the
Registration Statement and Prospectus), in the operations, business, condition
or prospects of the Company and the Subsidiaries taken as a whole shall occur or
become known and (ii) no transaction which is material and unfavorable to the
Company shall have been entered into by the Company or any of the Subsidiaries.

         (j) Each of the Company, the Parent and the Selling Stockholder will,
at the time of purchase or additional time of purchase, as the case may be,
deliver to you a certificate of the Company, the Parent or the Selling
Stockholder, as the case may be, signed by two of its executive officers or
partners to the effect that the representations and warranties of the Company,
the Parent or the Selling Stockholder, as the case may be, as set forth in this
Agreement are true and correct as of each such date, that the Company, the
Parent or the Selling Stockholder, as the case may be, has performed

                                       30
<PAGE>

such of its obligations under this Agreement as are to be performed at or before
the time of purchase and at or before the additional time of purchase, as the
case may be, and the conditions set forth in paragraphs (h) and (i) of this
Section 6 have been met.

         (k) You shall have received signed letters, dated the date of this
Agreement, from each of the holders of Common Stock and securities convertible
into or exchangeable or exercisable for Common Stock (including the Parent and
the Selling Stockholder) in the form and to the effect contemplated by Section
3(i)(r).

         (l) The Company, the Parent and the Selling Stockholder shall have
furnished to you such other documents and certificates as to the accuracy and
completeness of any statement in the Registration Statement and the Prospectus
as of the time of purchase and the additional time of purchase, as the case may

         (m) The Shares shall have been approved for listing for quotation on
NASDAQ, subject only to notice of issuance at or prior to the time of purchase
or the additional time of purchase, as the case may be.

         (n) The Formation Transactions shall have been completed substantially
in the manner contemplated by the Prospectus.

         7. Effective Date of Agreement; Termination. This Agreement shall
become effective (i) if Rule 430A under the Act is not used, when you shall have
received notification of the effectiveness of the Registration Statement, or
(ii) if Rule 430A under the Act is used, when the parties hereto have executed
and delivered this Agreement.

         The obligations of the several Underwriters hereunder shall be subject
to termination in the absolute discretion of you or any group of Underwriters
(which may include you) which has agreed to purchase in the aggregate at least
50% of the Firm Shares, (a) if, since the time of execution of this Agreement or
the respective dates as of which information is given in the Registration
Statement and Prospectus, there has been any material adverse and unfavorable
change, financial or otherwise (other than as referred to in the Registration
Statement and Prospectus), in the operations, business, condition or prospects
of the Company and the Subsidiaries taken as a whole, which would, in your
judgment or in the judgment of such group of Underwriters, make it impracticable
to market the Shares, or (b) if, at any time prior to the time of purchase or,
with respect to the purchase of any Additional Shares, the additional time of
purchase, as the case may be, trading in securities on the New York Stock
Exchange, the American Stock Exchange or the Nasdaq National Market shall have
been suspended or limitations or minimum prices shall have been established on
the New York Stock Exchange, the American Stock Exchange or the Nasdaq National
Market, or

                                       31
<PAGE>

if a banking moratorium shall have been declared either by the United States or
New York State authorities, or if the United States shall have declared war in
accordance with its constitutional processes or there shall have occurred any
material outbreak or escalation of hostilities or other national or
international calamity or crisis of such magnitude in its effect on the
financial markets of the United States as, in your judgment or in the judgment
of such group of Underwriters, to make it impracticable to market the Shares.

         If any Underwriter elects to terminate this Agreement as provided in
this Section 7, the Company, the Parent, the Selling Stockholder and each other
Underwriter shall be notified promptly by letter or telegram from such
terminating Underwriter.

         If the sale to the Underwriters of the Shares, as contemplated by this
Agreement, is not carried out by the Underwriters for any reason permitted under
this Agreement or if such sale is not carried out because the Company, the
Parent or the Selling Stockholder shall be unable to comply with any of the
terms of this Agreement, the Company and the Parent shall not be under any
obligation or liability under this Agreement (except to the extent provided in
Sections 4(i)(1), 5 and 9 hereof), and the Underwriters shall be under no
obligation or liability to the Company, the Parent and the Selling Stockholder
under this Agreement (except to the extent provided in Section 9 hereof) or to
one another hereunder.

         8. Increase in Underwriters' Commitments. Subject to Sections 6 and 7,
if any Underwriter shall default in its obligation to purchase and pay for the
Firm Shares to be purchased by it hereunder (otherwise than for a reason
sufficient to justify the termination of this Agreement under the provisions of
Section 7 hereof) and if the number of Firm Shares which all Underwriters so
defaulting shall have agreed but failed to purchase and pay for does not exceed
10% of the total number of Firm Shares, the non-defaulting Underwriters shall
purchase and pay for (in addition to the aggregate number of Firm Shares they
are obligated to purchase pursuant to Section 1 hereof) the number of Firm
Shares agreed to be purchased by all such defaulting Underwriters, as
hereinafter provided. Such Shares shall be purchased and paid for by such
non-defaulting Underwriter or Underwriters in such amount or amounts as you may
designate with the consent of each Underwriter so designated or, in the event no
such designation is made, such Shares shall be purchased and paid for by all
non-defaulting Underwriters pro rata in proportion to the aggregate number of
Firm Shares set opposite the names of such non-defaulting Underwriters in
Schedule A.

         Without relieving any defaulting Underwriter from its obligations
hereunder, the Company and the Selling Stockholder agree with the non-defaulting
Underwriters that they will not sell any Firm Shares hereunder unless all of the
Firm Shares are purchased by the Underwriters (or by substituted Underwriters
selected by you with the approval of the Company and the Selling Stockholder or
selected by the Company and the Selling Stockholder with your approval).

                                       32
<PAGE>

         If a new Underwriter or Underwriters are substituted by the
Underwriters or by the Company and the Selling Stockholder for a defaulting
Underwriter or Underwriters in accordance with the foregoing provision, the
Company and the Selling Stockholder or you shall have the right to postpone the
time of purchase for a period not exceeding five business days in order that any
necessary changes in the Registration Statement and Prospectus and other
documents may be effected.

         The term Underwriter as used in this Agreement shall refer to and
include any Underwriter substituted under this Section 8 with like effect as if
such substituted Underwriter had originally been named in Schedule A.

         If the aggregate number of Shares which the defaulting Underwriter or
Underwriters agreed to purchase exceeds 10% of the total number of Shares which
all Underwriters agreed to purchase hereunder, and if neither the non-defaulting
Underwriters nor the Company shall make arrangements within the five business
day period stated above for the purchase of all the Shares which the defaulting
Underwriter or Underwriters agreed to purchase hereunder, this Agreement shall
be terminated without further act or deed and without any liability on the part
of the Company, the Parent and the Selling Stockholder to any non-defaulting
Underwriter and without any liability on the part of any non-defaulting
Underwriter to the Company, the Parent and the Selling Stockholder. Nothing in
this paragraph, and no action taken hereunder, shall relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

         9. Indemnity and Contribution.

         (a) The Company, the Parent and the Selling Stockholder jointly and
severally agree to indemnify, defend and hold harmless each Underwriter, its
partners, directors and officers, and any person who controls any Underwriter
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act,
and the successors and assigns of all of the foregoing persons from and against
any loss, damage, expense, liability or claim (including the reasonable cost of
investigation) which, jointly or severally, any such Underwriter or any such
person may incur under the Act, the Exchange Act, the common law or otherwise,
insofar as such loss, damage, expense, liability or claim arises out of or is
based upon any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement (or in the Registration Statement as
amended by any post-effective amendment thereof by the Company) or in a
Prospectus (the term Prospectus for the purpose of this Section 9 being deemed
to include any Preliminary Prospectus, the Prospectus and the Prospectus as
amended or supplemented by the Company), or arises out of or is based upon any
omission or alleged omission to state a material fact required to be stated in
either such Registration Statement or Prospectus or necessary to make the
statements made therein not misleading, except insofar as any such loss, damage,
expense, liability or claim arises out of

                                       33
<PAGE>

or is based upon any untrue statement or alleged untrue statement of a material
fact contained in and in conformity with information furnished in writing by or
on behalf of any Underwriter (in its capacity as such) through you (in your
capacity as representatives of the several Underwriters) to the Company
expressly for use with reference to such Underwriter (in its capacity as such)
in such Registration Statement or such Prospectus or arises out of or is based
upon any omission or alleged omission to state a material fact in connection
with such information required to be stated in such Registration Statement or
such Prospectus or necessary to make such information not misleading, provided,
however, that the indemnity agreement contained in this subsection (a) with
respect to any Preliminary Prospectus or amended Preliminary Prospectus shall
not inure to the benefit of any Underwriter from whom the person asserting any
such loss, damage, expense, liability or claim purchased the Shares which is the
subject thereof if the Prospectus corrected any such alleged untrue statement or
omission and if such Underwriter failed to send or give a copy of the Prospectus
to such person at or prior to the written confirmation of the sale of such
Shares to such person, unless the failure is the result of noncompliance by the
Company with Section 4(i)(g) hereof

         If any action, suit or proceeding (together, a "Proceeding") is brought
against an Underwriter or any such person in respect of which indemnity may be
sought against the Company, the Parent and the Selling Stockholder pursuant to
the foregoing paragraph, such Underwriter or such person shall promptly notify
the Company, the Parent and the Selling Stockholder in writing of the
institution of such Proceeding and the Company shall assume the defense of such
Proceeding, including the employment of counsel reasonably satisfactory to such
indemnified party and payment of all fees and expenses; provided, however, that
the omission to so notify the Company, the Parent and the Selling Stockholder
shall not relieve the Company, the Parent and the Selling Stockholder from any
liability which the Company, the Parent and the Selling Stockholder may have to
any Underwriter or any such person or otherwise. Such Underwriter or such person
shall have the right to employ its or their own counsel in any such case, but
the fees and expenses of such counsel shall be at the expense of such
Underwriter or of such person unless the employment of such counsel shall have
been authorized in writing by the Company in connection with the defense of such
Proceeding or the Company shall not have, within a reasonable period of time in
light of the circumstances, employed counsel to have charge of the defense of
such Proceeding or such indemnified party or parties shall have reasonably
concluded, based on the written advice of counsel, that there may be defenses
available to it or them which are different from, additional to or in conflict
with those available to the Company, the Parent and the Selling Stockholder (in
which case the Company shall not have the right to direct the defense of such
Proceeding on behalf of the indemnified party or parties), in any of which
events such fees and expenses shall be borne by the Company, the Parent and the
Selling Stockholder and paid as incurred (it being understood, however, that the
Company, the Parent and the Selling Stockholder shall not be liable for the
expenses of more than one separate counsel (in addition to any local counsel) in


                                       34
<PAGE>

any one Proceeding or series of related Proceedings in the same jurisdiction
representing the indemnified parties who are parties to such Proceeding). The
Company, the Parent and the Selling Stockholder shall not be liable for any
settlement of any Proceeding effected without the Company's written consent but
if settled with the written consent of the Company, the Company, the Parent and
the Selling Stockholder jointly and severally agree to indemnify and hold
harmless any Underwriter and any such person from and against any loss or
liability by reason of such settlement. Notwithstanding the foregoing sentence,
if at any time an indemnified party shall have requested an indemnifying party
to reimburse the indemnified party for fees and expenses of counsel as
contemplated by the second sentence of this paragraph, then the indemnifying
party agrees that it shall be liable for any settlement of any Proceeding
effected without the Company's written consent if (i) such settlement is entered
into more than 60 business days after receipt by the indemnifying party of the
aforesaid request, (ii) such indemnifying party shall not have reimbursed the
indemnified party in accordance with such request prior to the date of such
settlement and (iii) such indemnified party shall have given the indemnifying
party at least 30 days' prior notice of its intention to settle. No indemnifying
party shall, without the prior written consent of the indemnified party, effect
any settlement of any pending or threatened Proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such Proceeding and does not include an admission
of fault, culpability or a failure to act, by or on behalf of such indemnified
party.

         (b) Each Underwriter severally agrees to indemnify, defend and hold
harmless the Company, its directors and officers, and any person who controls
the Company within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, the Parent and the Selling Stockholder and the successors and
assigns of all of the foregoing persons from and against any loss, damage,
expense, liability or claim (including the reasonable cost of investigation)
which, jointly or severally, the Company, the Parent, the Selling Stockholder or
any such person may incur under the Act, the Exchange Act, the common law or
otherwise, insofar as such loss, damage, expense, liability or claim arises out
of or is based upon any untrue statement or alleged untrue statement of a
material fact contained in and in conformity with information furnished in
writing by or on behalf of such Underwriter (in its capacity as such) through
you (in your capacity as representatives of the several Underwriters) to the
Company expressly for use with reference to such Underwriter (in its capacity as
such) in the Registration Statement (or in the Registration Statement as amended
by any post-effective amendment thereof by the Company) or in a Prospectus, or
arises out of or is based upon any omission or alleged omission to state a
material fact in connection with such information required to be stated in such
Registration Statement or such Prospectus or necessary to make such information
not misleading.

                                       35
<PAGE>

         If any Proceeding is brought against the Company, the Parent, the
Selling Stockholder or any such person in respect of which indemnity may be
sought against any Underwriter pursuant to the foregoing paragraph, the Company,
the Parent, the Selling Stockholder or such person shall promptly notify such
Underwriter in writing of the institution of such Proceeding and such
Underwriter shall assume the defense of such Proceeding, including the
employment of counsel reasonably satisfactory to such indemnified party and
payment of all fees and expenses; provided, however, that the omission to so
notify such Underwriter shall not relieve such Underwriter from any liability
which such Underwriter may have to the Company, the Parent, the Selling
Stockholder or any such person or otherwise. The Company, the Parent, the
Selling Stockholder or such person shall have the right to employ its own
counsel in any such case, but the fees and expenses of such counsel shall be at
the expense of the Company, the Parent, the Selling Stockholder or such person
unless the employment of such counsel shall have been authorized in writing by
such Underwriter in connection with the defense of such Proceeding or such
Underwriter shall not have, within a reasonable period of time in light of the
circumstances, employed counsel to have charge of the defense of such Proceeding
or such indemnified party or parties shall have reasonably concluded, based on
the written advice of counsel, that there may be defenses available to it or
them which are different from or additional to or in conflict with those
available to such Underwriter (in which case such Underwriter shall not have the
right to direct the defense of such Proceeding on behalf of the indemnified
party or parties, but such Underwriter may employ counsel and participate in the
defense thereof but the fees and expenses of such counsel shall be at the
expense of such Underwriter), in any of which events such fees and expenses
shall be borne by such Underwriter and paid as incurred (it being understood,
however, that such Underwriter shall not be liable for the expenses of more than
one separate counsel (in addition to any local counsel) in any one Proceeding or
series of related Proceedings in the same jurisdiction representing the
indemnified parties who are parties to such Proceeding). No Underwriter shall be
liable for any settlement of any such Proceeding effected without the written
consent of such Underwriter but if settled with the written consent of such
Underwriter, such Underwriter agrees to indemnify and hold harmless the Company,
the Parent, the Selling Stockholder and any such person from and against any
loss or liability by reason of such settlement. Notwithstanding the foregoing
sentence, if at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel as contemplated by the second sentence of this paragraph, then the
indemnifying party agrees that it shall be liable for any settlement of any
Proceeding effected without its written consent if (i) such settlement is
entered into more than 60 business days after receipt by such indemnifying party
of the aforesaid request, (ii) such indemnifying party shall not have reimbursed
the indemnified party in accordance with such request prior to the date of such
settlement and (iii) such indemnified party shall have given the indemnifying
party at least 30 days' prior notice of its intention to settle. No indemnifying
party shall, without the prior written consent of the indemnified party, effect

                                       36
<PAGE>

any settlement of any pending or threatened Proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such Proceeding.

         (c) The Company, the Parent and the Selling Stockholder hereby confirm
that at their request WDR has without compensation acted as "qualified
independent underwriter" (in such capacity, the "QIU") within the meaning of
Rule 2720 of the Conduct Rules of NASDR in connection with the offering of the
Shares. The Company, the Parent, and the Selling Stockholder agree to indemnify
and hold harmless the QIU, the directors, officers, employees and agents of the
QIU and each person who controls the QIU within the meaning of either the Act or
the Exchange Act against any and all losses, damages, expenses, liabilities, or
claims, joint or several, to which they or any of them may become subject under
the Act, the Exchange Act or other federal or state statutory law or regulation,
at common law or otherwise, insofar as such losses, damages, expenses,
liabilities or claims (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement for the registration of the Shares as
originally filed or in any amendment thereof, or in any Preliminary Prospectus
or the Prospectus, or in any amendment thereof or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and agrees to reimburse each such indemnified party, as
incurred, for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, damage, expense,
liability or claim; provided, however, that none of the Company, the Parent or
the Selling Stockholder will be liable in any such case to the extent that any
such loss, damage, expense, liability or claim arises out of or is based upon
any such untrue statement or alleged untrue statement or omission or alleged
omission made therein in reliance upon and in conformity with written
information furnished to the Company by or on behalf of the QIU (in its capacity
as such) through the representatives of the several Underwriters (in their
capacity as such) specifically for inclusion therein. This indemnity agreement
will be in addition to any liability that the Company, the Parent and the
Selling Stockholder may otherwise have.

         (d) If the indemnification provided for in this Section 9 is
unavailable to an indemnified party under subsections (a), (b) and (c) of this
Section 9 in respect of any losses, damages, expenses, liabilities or claims
referred to therein, then each applicable indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, damages, expenses,
liabilities or claims (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company, the Parent and the Selling
Stockholder on the one hand and the Underwriters on the other hand from the
offering of the Shares or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the

                                       37
<PAGE>

relative benefits referred to in clause (i) above but also the relative fault of
the Company, the Parent and the Selling Stockholder on the one hand and of the
Underwriters on the other in connection with the statements or omissions which
resulted in such losses, damages, expenses, liabilities or claims, as well as
any other relevant equitable considerations. The relative benefits received by
the Company, the Parent and the Selling Stockholder on the one hand and the
Underwriters on the other shall be deemed to be in the same respective
proportions as the total proceeds from the offering (net of underwriting
discounts and commissions but before deducting expenses) received by the Company
and the Selling Stockholder and the total underwriting discounts and commissions
received by the Underwriters, bear to the aggregate public offering price of the
Shares. Benefits received by the QIU in its capacity as "qualified independent
underwriter" shall be deemed to be equal to the compensation received by the QIU
acting in such capacity. The relative fault of the Company, the Parent and the
Selling Stockholder on the one hand and of the Underwriters on the other shall
be determined by reference to, among other things, whether the untrue statement
or alleged untrue statement of a material fact or omission or alleged omission
relates to information supplied by the Company, the Parent or by the Selling
Stockholder or by the Underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The amount paid or payable by a party as a result of the losses,
damages, expenses, liabilities and claims referred to in this subsection shall
be deemed to include any legal or other fees or expenses reasonably incurred by
such party in connection with investigating, preparing to defend or defending
any Proceeding.

         (e) The Company, the Parent and the Selling Stockholder and the
Underwriters agree that it would not be just and equitable if contribution
pursuant to this Section 9 were determined by pro rata allocation (even if the
Underwriters were treated as one entity for such purpose) or by any other method
of allocation that does not take account of the equitable considerations
referred to in subsection (d) above. Notwithstanding the provisions of this
Section 9, in no case shall (i) any Underwriter be required to contribute any
amount in excess of the amount by which the total price at which the Shares
underwritten by such Underwriter and distributed to the public were offered to
the public exceeds the amount of any damage which such Underwriter has otherwise
been required to pay by reason of such untrue statement or alleged untrue
statement or omission or alleged omission or (ii) the QIU in its capacity as
such be responsible for any amount in excess of the compensation received by the
QIU for acting in such capacity. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute pursuant to this
Section 9 are several in proportion to their respective underwriting commitments
and not joint.

                                       38
<PAGE>

         (f) The indemnity and contribution agreements contained in this Section
9 and the covenants, warranties and representations of the Company, the Parent
and the Selling Stockholder contained in this Agreement shall remain in full
force and effect regardless of any investigation made by or on behalf of any
Underwriter, its partners, directors or officers or any person (including each
partner, officer or director of such person) who controls any Underwriter within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or
on behalf of either of the Company, the Parent or the Selling Stockholder, their
directors or officers or any person who controls any of the Company, the Parent
or the Selling Stockholder within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, and shall survive any termination of this
Agreement or the issuance and delivery of the Shares. The Company, the Parent,
the Selling Stockholder and each Underwriter agree promptly to notify each other
of the commencement of any Proceeding against it and, in the case of the
Company, the Parent or the Selling Stockholder, against any of the officers,
directors or partners of the Company, the Parent or the Selling Stockholder, as
the case may be, in connection with the issuance and sale of the Shares, or in
connection with the Registration Statement or Prospectus.

         10. Directed Share Program

         (a) As part of the offering contemplated by this Agreement, the
Underwriters agree to reserve out of the Shares up to 425,000 Shares for sale to
the employees, officers, and directors of the Company and the Parent and other
parties associated with the Company and the Parent (collectively,
"Participants"), as set forth in the Prospectus under the heading "Underwriting"
(the "Directed Share Program"). The Shares to be sold by the Underwriters
pursuant to the Directed Share Program will be sold by the Underwriters pursuant
to this Agreement at the public offering price. Any Directed Shares not
purchased by Participants will be offered to the public by the Underwriters as
set forth in the Prospectus.

         (b) With respect to Directed Shares sold outside the United States, the
Company and the Parent represent and warrant to the Underwriters that (i) the
Registration Statement, the Prospectus, each Preliminary Prospectus and all
other materials distributed in connection with the Directed Share Program comply
in all material respects, and any further amendments or supplements to any of
the foregoing will comply in all material respects, with any applicable laws or
regulations of foreign jurisdictions in which the Prospectus, any Preliminary
Prospectus, as amended or supplemented, and any additional materials are
distributed in connection with the Directed Share Program and that (ii) no
authorization, approval, consent, license, order, registration or qualification
of or with any government, governmental instrumentality or court, other than
such as have been obtained, is necessary under the securities laws and
regulations of foreign jurisdictions in which the Directed Shares are offered
outside the United States. The Company and the Parent covenant with the
Underwriters that the Company and the Parent will comply in all material
respects with all

                                       39
<PAGE>

applicable securities and other applicable laws, rules and regulations in each
foreign jurisdiction in which the Directed Shares are offered in connection with
the Directed Share Program.

         (c) The Company and the Parent will ensure that the Directed Shares
will be restricted to the extent required by the NASD or the NASD rules from
sale, transfer, assignment, pledge or hypothecation for a period of three months
following the date of the effectiveness of the Registration Statement. WDR will
notify the Company as to which Participants will need to be so restricted. The
Company will direct the removal of such transfer restrictions upon the
expiration of such period of time.

         (d) The Company and the Parent agree, jointly and severally, to
indemnify and hold harmless each Underwriter and the QIU, their respective
partners, directors and officers, and any person who controls any Underwriter or
the QIU within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, and the successors and assigns of all of the foregoing persons,
from and against any loss, damage, expense, liability or claim (including the
reasonable cost of investigation) related to, arising out of, or in connection
with the Directed Share Program, provided that, the Company and the Parent shall
not be responsible for any loss, damage, expense, liability or claim that is
finally judicially determined to have resulted from the bad faith or gross
negligence of the Underwriters.

         11. Notices. Except as otherwise herein provided, all statements,
requests, notices and agreements shall be in writing or by telegram and, if to

Agreement.

                               WARRANT AGREEMENT

                  THIS WARRANT AGREEMENT, dated as of _______________, 1999 by
and between eSpeed, Inc., a Delaware corporation (the "Company"), and Martin J.
Wygod (the "Grantee").

In accordance with the letter agreement dated as of _______________ by and
between the Company and the Grantee, and in consideration for the services
rendered pursuant thereto, the Company hereby grants to the Grantee a warrant
(the "Warrant") to purchase shares of the Company's Class A Common Stock (the
"Shares") on the following terms and conditions:

1.   Number of Shares. The number of Shares subject to the Warrant shall
     equal _________.

2.   Exercise Price. The exercise price per Share subject to the Warrant shall
     equal $_____.

3.   Exercisability/Termination. The Warrant shall be fully exercisable only
     during the four year period commencing on the first anniversary hereof and
     ending on the fifth anniversary hereof, at which time any unexercised
     portion of the Warrant shall terminate. Notwithstanding the foregoing, the
     Warrant shall terminate upon the consummation of any transaction whereby
     the Company (or any successor to the Company or substantially all of its
     business) becomes a wholly-owned subsidiary of any corporation or other
     entity, unless such other corporation or entity shall continue or assume
     the Warrant (in which case such other corporation or entity shall be
     treated as the Company for all purposes hereunder, and shall make
     appropriate adjustment pursuant to paragraph 5 below in the number and
     kind of shares of stock subject thereto and the exercise price per share
     thereof to reflect consummation of such transaction). If the Warrant is
     not to be so assumed, the Company shall notify the Grantee of consummation
     of such transaction at least ten days in advance thereof.

4.   Exercise Procedures. The Grantee shall exercise the Warrant by delivery of
     written notice to the Company setting forth the number of Shares with
     respect to which the Warrant is to be exercised, together with a certified
     check or bank draft payable to the order of the Company for an amount
     equal to the sum of the exercise price for such Shares.

5.   Adjustment Upon Changes in Capitalization. In the event any
     recapitalization, forward or reverse split, reorganization, merger,
     consolidation, spin-off, combination, repurchase, or exchange of Shares or
     other securities, any special and nonrecurring dividend or distribution
     (whether in the form of cash, securities or other property), liquidation,
     dissolution, or other similar transactions or events, affects the Shares
     such that an adjustment is, in the sole discretion of the Company,
     appropriate in order to prevent dilution or enlargement of the rights of
     the Grantee, then the Company shall equitably adjust (i) the number and
     kind of Shares that may be delivered or deliverable in respect of the
     Warrant, and/or (ii) the exercise price. In addition, the Company is
     authorized to make adjustments in the terms and conditions of, and the
     criteria included in, the Warrant (including, without limitation,

<PAGE>

     cancellation of the Warrant in exchange for its in-the-money value, if
     any, or substitution of the Warrant using stock of a successor or other
     entity) in recognition of unusual or nonrecurring events (including,
     without limitation, an event described in the preceding sentence)
     affecting the Company or any subsidiary of the Company or the financial
     statements of the Company or any subsidiary of the Company, or in response
     to changes in applicable laws, regulations, or accounting principles.

6.   Restrictions on Issuing Stock. The Company shall not be obligated to issue
     or deliver Shares upon exercise of the Warrant or take any other action in
     a transaction subject to the requirements of any applicable securities
     law, any requirement under any listing agreement between the Company and
     any national securities exchange or automated quotation system or any
     other law, regulation or contractual obligation of the Company until the
     Company is satisfied that such laws, regulations, and other obligations of
     the Company have been complied with in full. Certificates representing
     Shares issued pursuant to exercise of the Warrant will be subject to such
     stop-transfer orders and other restrictions as may be applicable under
     such laws, regulations and other obligations of the Company, including any
     requirement that a legend or legends be placed thereon.

7.   Limitations on Transferability. The Warrant will not be transferable by
     the Grantee except by will or the laws of descent and distribution or to a
     beneficiary in the event of the Grantee's death, shall not be pledged,
     mortgaged, hypothecated or otherwise encumbered, or otherwise subject to
     the claims of creditors; provided, however, that the Warrant or any
     portion thereof may be transferred by the Grantee to (a) trusts
     established for the benefit of his children, stepchildren and
     grandchildren or (b) charities. Any such transferee shall be bound by the
     terms of this Agreement.

8.   Taxes. The Grantee shall be responsible for the payment of all income,
     social security taxes and Medicare taxes related to the exercise of the
     Warrant, and shall indemnify the Company against any liability it may
     incur with respect to such taxes, including by reason of the Company not
     withholding any such taxes on behalf of the Grantee.

9.   No Stockholder Rights. The Warrant shall not confer on the Grantee any of
     the rights of a stockholder of the Company unless and until Shares are
     duly issued or transferred and delivered to the Grantee upon exercise of
     the Warrant.

10.  Piggyback Registration Rights. If the Company intends to register
     securities of any of its shareholders for an offering to the public while
     the Warrant is exercisable, the Company shall notify the Grantee of its
     intention to do so and, subject to such limitations as shall affect all
     selling shareholders equally and as may be imposed by any underwriter of
     such offering or by law, the Grantee may irrevocably elect to participate
     in such offering on a pari passu basis with any other selling shareholders
     (other than Cantor Fitzgerald L.P. or its affiliates, who shall have
     priority over the Grantee on any cutback) based on the relative number of
     shares owned and options or warrants vested of each of such other selling
     shareholders (and its



                                       2
<PAGE>

     affiliates and permitted assigns) and the Grantee (the "Pari Passu
     Percentage"). Such participation shall be under the same terms and
     conditions as may apply to such other shareholders, provided that the
     Grantee shall not have any rights to select the underwriter or similar
     matters given to the other shareholders. The Grantee shall make any
     election within 30 days of receipt of such notice of intent to register by
     a writing given to the Secretary of the Company, which writing shall
     indicate his irrevocable election to sell in the intended offering, the
     number of Shares he wishes to sell and the portion thereof to be included
     by him. The Grantee's notice may not be for less than 50% of the number of
     Shares of the Grantee. The Grantee shall be responsible for delivery of
     the Shares covered by the notice on a timely basis. The Company shall only
     have to give notice of intent to register under this paragraph to the
     Grantee and any notice of intent to participate shall only be valid if
     received from the Grantee (or in the event of his death, his executor).
     The Company may at any time abandon any offering. The Company or the
     underwriter may at any time cutback (including, without limitation,
     limiting the amount to the extent a prior amount had not been specified)
     on the number of shares in any offering in which the Company is offering
     shares and the underwriter may at any time cutback (including, without
     limitation, limiting the amount to the extent a prior amount had not been
     specified) on the number of shares to be offered by shareholders in any
     offering in which the Company is not also offering shares. In either such
     case the Grantee's Shares to be offered shall be proportionately reduced
     so that the amounts offered by the Grantee and by other shareholders (and
     their affiliates and permitted assigns) satisfy the Pari Passu Percentage.
     The Grantee shall have no right to participate in any offering by the
     Company that does not include any shares owned by other shareholders and
     the provision of this paragraph shall not apply to any registration on
     Form S-8, or otherwise with regard to securities of compensatory plans of
     the Company, or any registration relating to business acquisitions on Form
     S-1 or Form S-4. The Grantee shall sign such underwriting and other
     agreements in the same forms as signed by the other participating
     shareholders.

11.  Demand Registration Right. Subject to the Company's qualification to use a
     Form S-3, from and after the date that is one year after the date hereof,
     the Grantee may request, in writing, registration (the "Demand
     Registration") under the Securities Act of 1933, as amended (the
     "Securities Act"), of all or a portion of the Shares and the Shares
     underlying the warrant granted on the date hereof to Pamela S. Wygod,
     Trustee under the Trust Agreement dated 12/30/87 for the benefit of Adam
     Yellin ("the "Other Shares") on Form S-3; provided, however, that such
     request must include at least 75% of the aggregate of the Shares and the
     Other Shares. Thereafter, the Company will use all reasonable efforts to
     effect the Demand Registration under the Securities Act within thirty (30)
     days after the receipt of the request. The Company shall not be required
     to effect the Demand Registration requested by the Grantee if either (a)
     within the six (6) months preceding the receipt by the Company of such
     request, the Company has filed a registration statement to which the
     Piggyback Registration rights set forth in Section 10 hereof apply or (b)
     such Grantee may sell the Shares and the Other Shares requested to be
     included in the Demand Registration without registration under the
     Securities Act, pursuant to the exemption provided by (i) Rule 144 under
     the Securities Act, as such rule may be amended from time to time, or (ii)
     any similar rule or registration



                                       3

     adopted by the Commission. The Granter shall be entitle to no more than
     one (1) Demand Registration. The Company agrees to keep the Demand
     Registration effective for a period of sixty (60) days beyond the
     effective date.

12.  Governing Law. This Agreement shall be governed by and construed in
     accordance with the laws of the State of New York.

         individual whose nomination for election to Board membership was not
         endorsed by the Company's management prior to, or at the time of, such

         this Agreement, considered as though such person were a member of the
         Incumbent Board; or

                  (iii) the consummation of a merger, consolidation,

national securities exchange or quoted in an interdealer quotation system, the
Fair Market Value of such Stock on a given date shall be based upon the last
sales price or, if unavailable, the average of the closing bid and asked prices

was no trading or quotation in the Stock on such date, on the next preceding
date on which there was trading or quotation) as provided by one of such

final authority to take the following actions, in each case subject to and
consistent with the provisions of the Plan:

                  (i) to select persons to whom Awards may be granted;

                  (ii) to determine the type or types of Awards to be granted to
         each such person;

                  (iii) to determine the number of Awards to be granted, the
         number of shares of Stock to which an Award will relate, the terms and
         conditions of any Award granted under the Plan (including, but not
         limited to, any exercise price, grant price or purchase price, any


                                        3

<PAGE>


         restriction or condition, any schedule for lapse of restrictions or
         conditions relating to transferability or forfeiture, exercisability or
         settlement of an Award, and waivers or accelerations thereof,
         performance conditions relating to an Award, based in each case on
         such considerations as the Committee shall determine), and all other
         matters to be determined in connection with an Award;

                  (iv) to determine whether, to what extent and under what
         circumstances an Award may be settled, or the exercise price of an
         Award may be paid, in cash, Stock, other Awards, or other property, or
         an Award may be canceled, forfeited, or surrendered;

                  (v) to determine whether, to what extent and under what
         circumstances cash, Stock, other Awards or other property payable with
         respect to an Award will be deferred either automatically, at the
         election of the Committee or at the election of the Participant;

                  (vi) to determine the restrictions, if any, to which Stock
         received upon exercise or settlement of an Award shall be subject
         (including lock-ups and other transfer restrictions), may condition the
         delivery of such Stock upon the execution by the Participant of any
         agreement providing for such restrictions;

                  (vii) to prescribe the form of each Award Agreement, which
         need not be identical for each Participant;

                  (viii) to adopt, amend, suspend, waive and rescind such rules
         and regulations and appoint such agents as the Committee may deem
         necessary or advisable to administer the Plan;

                  (ix) to correct any defect or supply any omission or reconcile
         any inconsistency in the Plan and to construe and interpret the Plan
         and any Award, rules and regulations, Award Agreement or other
         instrument hereunder; and

                  (x) to make all other decisions and determinations as may be
         required under the terms of the Plan or as the Committee may deem
         necessary or advisable for the administration of the Plan.

Other provisions of the Plan notwithstanding, the Board shall perform the
functions of the Committee for purposes of granting awards to directors who
serve on the Committee, and the Board may perform any function of the Committee
under the Plan for any other purpose, including without limitation for the
purpose of ensuring that transactions under the Plan by Participants who are
then subject to Section 16 of the Exchange Act in respect of the Company are
exempt under Rule 16b-3. In any case in which the Board is performing a function
of the Committee under the Plan, each reference to the Committee herein shall be
deemed to refer to the Board, except where the context otherwise requires.


                                        4

<PAGE>



         (b) Manner of Exercise of Committee Authority. Any action of the
Committee with respect to the Plan shall be final, conclusive and binding on all
persons, including the Company, its Parent and Subsidiaries, Participants, any
person claiming any rights under the Plan from or through any Participant and
stockholders, except to the extent the Committee may subsequently modify, or
take further action not consistent with, its prior action. If not specified in
the Plan, the time at which the Committee must or may make any determination
shall be determined by the Committee, and any such determination may thereafter
be modified by the Committee (subject to Section 8(e)). The express grant of any
specific power to the Committee, and the taking of any action by the Committee,
shall not be construed as limiting any power or authority of the Committee. The
Committee may delegate to officers or managers of the Company, its Parent or
Subsidiaries the authority, subject to such terms as the Committee shall
determine, to perform such functions as the Committee may determine, to the
extent permitted under applicable law.

         (c) Limitation of Liability; Indemnification. Each member of the
Committee shall be entitled to, in good faith, rely or act upon any report or
other information furnished to him by any officer or other employee of the
Company , its Parent or Subsidiaries, the Company's independent certified public
accountants or any executive compensation consultant, legal counsel or other
professional retained by the Company to assist in the administration of the
Plan. No member of the Committee, or any officer or employee of the Company
acting on behalf of the Committee, shall be personally liable for any action,
determination or interpretation taken or made in good faith with respect to the
Plan, and all members of the Committee and any officer or employee of the
Company acting on its behalf shall, to the extent permitted by law, be fully
indemnified and protected by the Company with respect to any such action,
determination or interpretation.

         4.       Stock Subject to Plan.

         (a) Amount of Stock Reserved. The total number of shares of Stock that
may be subject to outstanding Awards, determined immediately after the grant of
any Award, shall not exceed 20% of the total number of shares of all classes of
the Company's common stock outstanding at the effective time of such grant. In
no event shall the number of shares of Stock delivered upon the exercise of ISOs
exceed 10,000,000; provided, however, that shares subject to ISOs shall not be
deemed delivered if such ISOs are forfeited, expire or otherwise terminate
without delivery of shares to the Participant. If an Award valued by reference
to Stock may only be settled in cash, the number of shares to which such Award
relates shall be deemed to be Stock subject to such Award for purposes of this
Section 4(a). Any shares of Stock delivered pursuant to an Award may consist, in
whole or in part, of authorized and unissued shares, treasury shares or shares
acquired in the market on a Participant's behalf.

         (b) Adjustments. In the event that the Committee shall determine that
any recapitalization, forward or reverse split, reorganization, merger,
consolidation, spin-off, combination, repurchase or exchange of Stock or other
securities, Stock dividend or other special, large and non-recurring dividend or
distribution (whether in the form of cash, securities or other property),
liquidation, dissolution, or other similar corporate transaction or event,
affects the Stock


                                        5

<PAGE>


such that an adjustment is appropriate in order to prevent dilution or
enlargement of the rights of Participants under the Plan, then the Committee
shall, in such manner as it may deem equitable, adjust any or all of (i) the
number and kind of shares of Stock reserved and available for Awards under
Section 4(a), including shares reserved for ISOs, (ii) the number and kind of
shares of outstanding Restricted Stock or other outstanding Awards in connection
with which shares have been issued, (iii) the number and kind of shares that may
be issued in respect of other outstanding Awards and (iv) the exercise price,
grant price or purchase price relating to any Award. (or, if deemed appropriate,
the Committee may make provision for a cash payment with respect to any
outstanding Award). In addition, the Committee is authorized to make adjustments
in the terms and conditions of, and the criteria included in, Awards (including,
without limitation, cancellation of unexercised or outstanding Awards, or
substitution of Awards using stock of a successor or other entity) in
recognition of unusual or nonrecurring events (including, without limitation,
events described in the preceding sentence and events constituting a Change in
Control) affecting the Company, its Parent or any Subsidiary or the financial
statements of the Company, its Parent or any Subsidiary, or in response to
changes in applicable laws, regulations, or accounting principles.

         5. Eligibility. Directors, officers and employees of the Company or its
Parent or any Subsidiary, and persons who provide consulting or other services
to the Company, its Parent or any Subsidiary deemed by the Committee to be of
substantial value to the Company or its Parent and Subsidiaries, are eligible to
be granted Awards under the Plan. In addition, persons who have been offered
employment by, or agreed to become a director of, the Company, its Parent or any
Subsidiary, and persons employed by an entity that the Committee reasonably
expects to become a Subsidiary of the Company, are eligible to be granted an
Award under the Plan.

         6.       Specific Terms of Awards.

         (a) General. Awards may be granted on the terms and conditions set
forth in this Section 6. In addition, the Committee may impose on any Award or
the exercise thereof such additional terms and conditions, not inconsistent with
the provisions of the Plan, as the Committee shall determine, including terms
requiring forfeiture of Awards in the event of termination of employment or
service of the Participant. Except as expressly provided by the Committee
(including for purposes of complying with the requirements of the Delaware
General Corporation Law relating to lawful consideration for the issuance of
shares), no consideration other than services will be required as consideration
for the grant (but not the exercise) of any Award.

         (b) Options. The Committee is authorized to grant options to purchase
Stock (including "reload" options automatically granted to offset specified
exercises of Options) on the following terms and conditions ("Options"):

                  (i) Exercise Price. The exercise price per share of Stock
         purchasable under an Option shall be determined by the Committee.


                                        6

<PAGE>



                  (ii) Time and Method of Exercise. The Committee shall
         determine the time or times at which an Option may be exercised in
         whole or in part, the methods by which such exercise price may be paid
         or deemed to be paid, the form of such payment, including, without
         limitation, cash, Stock, other Awards or awards granted under other
         Company plans or other property (including notes or other contractual
         obligations of Participants to make payment on a deferred basis, such
         as through "cashless exercise" arrangements, to the extent permitted by
         applicable law), and the methods by which Stock will be delivered or
         deemed to be delivered to Participants.

                  (iii) Termination of Employment. The Committee shall determine
         the period, if any, during which Options shall be exercisable following
         a Participant's termination of his employment relationship with the
         Company , its Parent or any Subsidiary. For this purpose, any sale of a
         Subsidiary of the Company pursuant to which it ceases to be a
         Subsidiary of the Company shall be deemed to be a termination of
         employment by any Participant employed by such Subsidiary. Unless
         otherwise determined by the Committee, (i) during any period that an
         Option is exercisable following termination of employment, it shall be
         exercisable only to the extent it was exercisable upon such termination
         of employment, and (ii) if such termination of employment is for cause,
         as determined in the discretion of the Committee, all Options held by
         the Participant shall immediately terminate.

                  (iv) Sale of the Company. Upon the consummation of any
         transaction whereby the Company (or any successor to the Company or
         substantially all of its business) becomes a wholly-owned Subsidiary of
         any corporation, all Options outstanding under the Plan shall terminate
         (after taking into account any accelerated vested pursuant to Section
         7(f)), unless such other corporation shall continue or assume the Plan
         as it relates to Options then outstanding (in which case such other
         corporation shall be treated as the Company for all purposes hereunder,
         and, pursuant to Section 4(b), the Committee of such other corporation
         shall make appropriate adjustment in the number and kind of shares of
         Stock subject thereto and the exercise price per share thereof to
         reflect consummation of such transaction). If the Plan is not to be so
         assumed, the Company shall notify the Participant of consummation of
         such transaction at least ten days in advance thereof.

                  (v) Options Providing Favorable Tax Treatment. The Committee
         may grant Options that may afford a Participant with favorable
         treatment under the tax laws applicable to such Participant, including,
         but not limited to ISOs. If Stock acquired by exercise of an ISO is
         sold or otherwise disposed of within two years after the date of grant
         of the ISO or within one year after the transfer of such Stock to the
         Participant, the holder of the Stock immediately prior to the
         disposition shall promptly notify the Company in writing of the date
         and terms of the disposition and shall provide such other information
         regarding the disposition as the Company may reasonably require in
         order to secure any deduction then available against the Company's or
         any other corporation's taxable income. The Company may impose such
         procedures as it determines may be necessary to ensure that such


                                        7

<PAGE>


         notification is made. Each Option granted as an ISO shall be designated
         as such in the Award Agreement relating to such Option.

         (c) Stock Appreciation Rights. The Committee is authorized to grant
stock appreciation rights on the following terms and conditions ("SARs"):

                  (i) Right to Payment. An SAR shall confer on the Participant
         to whom it is granted a right to receive, upon exercise thereof, the
         excess of (A) the Fair Market Value of one share of Stock on the date
         of exercise (or, if the Committee shall so determine in the case of any
         such right other than one related to an ISO, the Fair Market Value of
         one share at any time during a specified period before or after the
         date of exercise), over (B) the grant price of the SAR as determined by
         the Committee as of the date of grant of the SAR, which, except as
         provided in Section 7(a), shall be not less than the Fair Market Value
         of one share of Stock on the date of grant.

                  (ii) Other Terms. The Committee shall determine the time or
         times at which an SAR may be exercised in whole or in part, the method
         of exercise, method of settlement, form of consideration payable in
         settlement, method by which Stock will be delivered or deemed to be
         delivered to Participants, whether or not an SAR shall be in tandem
         with any other Award, and any other terms and conditions of any SAR.
         Limited SARs that may only be exercised upon the occurrence of a Change
         in Control may be granted on such terms, not inconsistent with this
         Section 6(c), as the Committee may determine. Limited SARs may be
         either freestanding or in tandem with other Awards.

         (d) Restricted Stock. The Committee is authorized to grant Stock that
is subject to restrictions based on continued employment on the following terms
and conditions ("Restricted Stock"):

                  (i) Grant and Restrictions. Restricted Stock shall be subject
         to such restrictions on transferability and other restrictions, if any,
         as the Committee may impose, which restrictions may lapse separately or
         in combination at such times, under such circumstances, in such
         installments, or otherwise, as the Committee may determine. Except to
         the extent restricted under the terms of the Plan and any Award
         Agreement relating to the Restricted Stock, a Participant granted
         Restricted Stock shall have all of the rights of a stockholder
         including, without limitation, the right to vote Restricted Stock or
         the right to receive dividends thereon.

                  (ii) Forfeiture. Except as otherwise determined by the
         Committee, upon termination of employment or service (as determined
         under criteria established by the Committee) during the applicable
         restriction period, Restricted Stock that is at that time subject to
         restrictions shall be forfeited and reacquired by the Company;
         provided, however, that the Committee may provide, by rule or
         regulation or in any Award Agreement, or may determine in any
         individual case, that restrictions or forfeiture conditions relating to


                                        8

<PAGE>


         Restricted Stock will be waived in whole or in part in the event of
         termination resulting from specified causes.

                  (iii) Certificates for Stock. Restricted Stock granted under
         the Plan may be evidenced in such manner as the Committee shall
         determine. If certificates representing Restricted Stock are registered
         in the name of the Participant, such certificates may bear an
         appropriate legend referring to the terms, conditions, and restrictions
         applicable to such Restricted Stock, the Company may retain physical
         possession of the certificate, in which case the Participant shall be
         required to have delivered a stock power to the Company, endorsed in
         blank, relating to the Restricted Stock.

                  (iv) Dividends. Dividends paid on Restricted Stock shall be
         either paid at the dividend payment date in cash or in shares of
         unrestricted Stock having a Fair Market Value equal to the amount of
         such dividends, or the payment of such dividends shall be deferred
         and/or the amount or value thereof automatically reinvested in
         additional Restricted Stock, other Awards, or other investment
         vehicles, as the Committee shall determine or permit the Participant to
         elect. Stock distributed in connection with a Stock split or Stock
         dividend, and other property distributed as a dividend, shall be
         subject to restrictions and a risk of forfeiture to the same extent as
         the Restricted Stock with respect to which such Stock or other property
         has been distributed, unless otherwise determined by the Committee.

         (e) Deferred Stock. The Committee is authorized to grant units
representing the right to receive Stock at a future date subject to the
following terms and conditions ("Deferred Stock"):

                  (i) Award and Restrictions. Delivery of Stock will occur upon
         expiration of the deferral period specified for an Award of Deferred
         Stock by the Committee (or, if permitted by the Committee, as elected
         by the Participant). In addition, Deferred Stock shall be subject to
         such restrictions as the Committee may impose, if any, which
         restrictions may lapse at the expiration of the deferral period or at
         earlier specified times, separately or in combination, in installments
         or otherwise, as the Committee may determine.

                  (ii) Forfeiture. Except as otherwise determined by the
         Committee, upon termination of employment or service (as determined
         under criteria established by the Committee) during the applicable
         deferral period or portion thereof to which forfeiture conditions apply
         (as provided in the Award Agreement evidencing the Deferred Stock), all
         Deferred Stock that is at that time subject to such forfeiture
         conditions shall be forfeited; provided, however, that the Committee
         may provide, by rule or regulation or in any Award Agreement, or may
         determine in any individual case, that restrictions or forfeiture
         conditions relating to Deferred Stock will be waived in whole or in
         part in the event of termination resulting from specified causes.


                                        9

         (f) Bonus Stock and Awards in Lieu of Cash Obligations. The Committee
is authorized to grant Stock as a bonus, or to grant Stock or other Awards in
lieu of Company obligations to pay cash under other plans or compensatory
arrangements.

         (g) Dividend Equivalents. The Committee is authorized to grant awards
entitling the Participant to receive cash, Stock, other Awards or other property
equal in value to dividends paid with respect to a specified number of shares of
Stock ("Dividend Equivalents"). Dividend Equivalents may be awarded on a
free-standing basis or in connection with another Award. The Committee may
provide that Dividend Equivalents shall be paid or distributed when accrued or
shall be deemed to have been reinvested in additional Stock, Awards or other
investment vehicles, and subject to such restrictions on transferability and
risks of forfeiture, as the Committee may specify.

         (h) Other Stock-Based Awards. The Committee is authorized, subject to
limitations under applicable law, to grant such other Awards that may be
denominated or payable in, valued in whole or in part by reference to, or
otherwise based on, or related to, Stock and factors that may influence the
value of Stock, as deemed by the Committee to be consistent with the purposes of
the Plan, including, without limitation, convertible or exchangeable debt
securities, other rights convertible or exchangeable into Stock, purchase rights
for Stock, Awards with value and payment contingent upon performance of the
Company or any other factors designated by the Committee and Awards valued by
reference to the book value of Stock or the value of securities of or the
performance of specified Subsidiaries ("Other Stock Based Awards"). The
Committee shall determine the terms and conditions of such Awards. Stock issued
pursuant to an Award in the nature of a purchase right granted under this
Section 6(h) shall be purchased for such consideration, paid for at such times,
by such methods, and in such forms, including, without limitation, cash, Stock,
other Awards, or other property, as the Committee shall determine. Cash awards,
as an element of or supplement to any other Award under the Plan, may be granted
pursuant to this Section 6(h).

         7.       Certain Provisions Applicable to Awards.

         (a) Stand-Alone, Additional, Tandem, and Substitute Awards. Awards
granted under the Plan may, in the discretion of the Committee, be granted
either alone or in addition to, in tandem with or in substitution for any other
Award granted under the Plan or any award granted under any other plan of the
Company, its Parent or Subsidiaries or any business entity to be acquired by the
Company or a Subsidiary, or any other right of a Participant to receive payment
from the Company its Parent or Subsidiaries. Awards granted in addition to or in
tandem with other Awards or awards may be granted either as of the same time as
or a different time from the grant of such other Awards or awards.

         (b) Term of Awards. The term of each Award shall be for such period as
may be determined by the Committee; provided, however, that (i) in no event
shall the term of any ISO or an SAR granted in tandem therewith exceed a period
of ten years from the date of its grant (or such shorter period as may be
applicable under Section 422 of the Code), and (ii) the term of any Option


                                       10

<PAGE>



granted to a resident of the United Kingdom shall not exceed a period of ten
years from the date of its grant.

         (c) Form of Payment Under Awards. Subject to the terms of the Plan and
any applicable Award Agreement, payments to be made by the Company, its Parent
or Subsidiaries upon the grant, exercise or settlement of an Award may be made
in such forms as the Committee shall determine, including, without limitation,
cash, Stock, other Awards or other property, and may be made in a single payment
or transfer, in installments or on a deferred basis. Such payments may include,
without limitation, provisions for the payment or crediting of reasonable
interest on installment or deferred payments or the grant or crediting of
Dividend Equivalents in respect of installment or deferred payments denominated
in Stock.

         (d)      Rule 16b-3 Compliance.

                  (i) Six-Month Holding Period. Unless a Participant could
         otherwise dispose of equity securities, including derivative
         securities, acquired under the Plan without incurring liability under
         Section 16(b) of the Exchange Act, equity securities acquired under the
         Plan must be held for a period of six months following the date of such
         acquisition, provided that this condition shall be satisfied with
         respect to a derivative security if at least six months elapse from the
         date of acquisition of the derivative security to the date of
         disposition of the derivative security (other than upon exercise or
         conversion) or its underlying equity security.

                  (ii) Other Compliance Provisions. With respect to a
         Participant who is then subject to Section 16 of the Exchange Act in
         respect of the Company, the Committee shall implement transactions
         under the Plan and administer the Plan in a manner that will ensure
         that each transaction by such a Participant is exempt from liability
         under Rule 16b-3, except that such a Participant may be permitted to
         engage in a non-exempt transaction under the Plan if written notice has
         been given to the Participant regarding the non-exempt nature of such
         transaction. The Committee may authorize the Company to repurchase any
         Award or shares of Stock resulting from any Award in order to prevent a
         Participant who is subject to Section 16 of the Exchange Act from
         incurring liability under Section 16(b). Unless other wise specified by
         the Participant, equity securities, including derivative securities,
         acquired under the Plan which are disposed of by a Participant shall be
         deemed to be disposed of in the order acquired by the Participant.

         (e) Loan Provisions. With the consent of the Committee, and subject at
all times to, and only to the extent, if any, permitted under and in accordance
with, laws and regulations and other binding obligations or provisions
applicable to the Company, the Company may make, guarantee or arrange for a loan
or loans to a Participant with respect to the exercise of any Option or other
payment in connection with any Award, including the payment by a Participant of
any or all federal, state or local income or other taxes due in connection with
any Award. Subject to such limitations, the Committee shall have full authority
to decide whether to make a loan or loans hereunder and to determine the amount,
terms and provisions of any such loan or loans, including the interest rate to


                                       11

<PAGE>



be charged in respect of any such loan or loans, whether the loan or loans are
to be with or without recourse against the borrower, the terms on which the loan
is to be repaid and conditions, if any, under which the loan or loans may be
forgiven.

         (f) Acceleration upon a Change of Control. Notwithstanding anything
contained herein to the contrary, except as set forth in an Award Agreement, all
conditions and/or restrictions relating to the continued performance of services
and/or the achievement of performance objectives with respect to the
exercisability or full enjoyment of an Award shall lapse immediately prior to a
Change in Control.

         8.       General Provisions.

         (a) Compliance With Laws and Obligations. The Company shall not be
obligated to issue or deliver Stock in connection with any Award or take any
other action under the Plan in a transaction subject to the requirements of any
applicable securities law, any requirement under any listing agreement between
the Company and any national securities exchange or automated quotation system
or any other law, regulation or contractual obligation of the Company until the
Company is satisfied that such laws, regulations, and other obligations of the
Company have been complied with in full. Certificates representing shares of
Stock issued under the Plan will be subject to such stop-transfer orders and
other restrictions as may be applicable under such laws, regulations and other
obligations of the Company, including any requirement that a legend or legends
be placed thereon.

         (b) Limitations on Transferability. Awards and other rights under the
Plan will not be transferable by a Participant except by will or the laws of
descent and distribution or to a Beneficiary in the event of the Participant's
death, shall not be pledged, mortgaged, hypothecated or otherwise encumbered, or
otherwise subject to the claims of creditors, and, in the case of ISOs and SARs
in tandem therewith, shall be exercisable during the lifetime of a Participant
only by such Participant or his guardian or legal representative; provided,
however, that such Awards and other rights (other than ISOs and SARs in tandem
therewith) may be transferred to one or more transferees during the lifetime of
the Participant to the extent and on such terms as then may be permitted by the
Committee.

         (c) No Right to Continued Employment or Service. Neither the Plan nor
any action taken hereunder shall be construed as giving any employee, director
or other person the right to be retained in the employ or service of the
Company, its Parent or any Subsidiary, nor shall it interfere in any way with
the right of the Company, its Parent or any Subsidiary to terminate any
employee's employment or other person's service at any time or with the right of
the Board or stockholders to remove any director.

         (d) Taxes. The Company, its Parent and Subsidiaries are authorized to
withhold from any Award granted or to be settled, any delivery of Stock in
connection with an Award, any other payment relating to an Award or any payroll
or other payment to a Participant amounts of


                                       12

<PAGE>


withholding and other taxes due or potentially payable in connection with any
transaction involving an Award, and to take such other action as the Committee
may deem advisable to enable the Company, its Parent and Subsidiaries and
Participants to satisfy obligations for the payment of withholding taxes and
other tax obligations relating to any Award. This authority shall include
authority to withhold or receive Stock or other property and to make cash
payments in respect thereof in satisfaction of a Participant's tax obligations.

         (e) Changes to the Plan and Awards. The Board may amend, alter,
suspend, discontinue or terminate the Plan or the Committee's authority to grant
Awards under the Plan without the consent of stockholders or Participants,
except that any such action shall be subject to the approval of the Company's
stockholders at or before the next annual meeting of stockholders for which the
record date is after such Board action if such stockholder approval is required
by any federal or state law or regulation or the rules of any stock exchange or
automated quotation system on which the Stock may then be listed or quoted, and
the Board may otherwise, in its discretion, determine to submit other such
changes to the Plan to stockholders for approval; provided, however, that,
without the consent of an affected Participant, no such action may materially
impair the rights of such Participant under any Award theretofore granted to him
(as such rights are set forth in the Plan and the Award Agreement). The
Committee may waive any conditions or rights under, or amend, alter, suspend,
discontinue, or terminate, any Award theretofore granted and any Award Agreement
relating thereto; provided, however, that, without the consent of an affected
Participant, no such action may materially impair the rights of such Participant
under such Award (as such rights are set forth in the Plan and the Award
Agreement). Notwithstanding the foregoing, the Board or the Committee may take
any action (including actions affecting or terminating outstanding Awards) to
the extent necessary for a business combination in which the Company is a party
to be accounted for under the pooling-of-interests method of accounting under
Accounting Principles Board Opinion No. 16 (or any successor thereto). The Board
or the Committee shall also have the authority to establish separate sub-plans
under the Plan with respect to Participants resident in a particular
jurisdiction (the terms of which shall not be inconsistent with those of the
Plan) if necessary or desirable to comply with the applicable laws of such
jurisdiction.

         (f) No Rights to Awards; No Stockholder Rights. No person shall have
any claim to be granted any Award under the Plan, and there is no obligation for
uniformity of treatment of Participants and employees. No Award shall confer on
any Participant any of the rights of a stockholder of the Company unless and
until Stock is duly issued or transferred and delivered to the Participant in
accordance with the terms of the Award or, in the case of an Option, the Option
is duly exercised.

         (g) Unfunded Status of Awards; Creation of Trusts. The Plan is intended
to constitute an "unfunded" plan for incentive and deferred compensation. With
respect to any payments not yet made to a Participant pursuant to an Award,
nothing contained in the Plan or any Award shall give any such Participant any
rights that are greater than those of a general creditor of the Company;
provided, however, that the Committee may authorize the creation of trusts or
make other arrangements to meet the Company's obligations under the Plan to
deliver cash, Stock, other


                                       13

<PAGE>


Awards, or other property pursuant to any Award, which trusts or other
arrangements shall be consistent with the "unfunded" status of the Plan unless
the Committee otherwise determines with the consent of each affected
Participant.

         (h) Nonexclusivity of the Plan. Neither the adoption of the Plan by the
Board nor any submission of the Plan or amendments thereto to the stockholders
of the Company for approval shall be construed as creating any limitations on
the power of the Board to adopt such other compensatory arrangements as it may
deem desirable, including, without limitation, the granting of stock options
otherwise than under the Plan, and such arrangements may be either applicable
generally or only in specific cases.

         (i) No Fractional Shares. No fractional shares of Stock shall be issued
or delivered pursuant to the Plan or any Award. The Committee shall determine
whether cash, other Awards, or other property shall be issued or paid in lieu of
such fractional shares or whether such fractional shares or any rights thereto
shall be forfeited or otherwise eliminated.

         (j) Governing Law. The validity, construction and effect of the Plan,
any rules and regulations relating to the Plan and any Award Agreement shall be
determined in accordance with the laws of the State of Delaware, without giving
effect to principles of conflicts of laws, and applicable federal law.

         (k) Effective Date; Plan Termination. The Plan shall become effective
as of the date of its adoption by the Board, and shall continue in effect until
terminated by the Board.

                   1999 Long-Term Incentive Plan ("the Plan")

                                   UK Appendix




NOTE: The Company will be granting only Options under the UK Appendix. Hence,
any references in the rules to any other Awards should be disregarded for the
purposes of the UK Appendix.

If the Board decides to grant an Option to a Director or Employee who is a
resident of the United Kingdom within the meaning of the Double Taxation Treaty
between the United Kingdom and the United States of America and whose emoluments
are liable to be paid under deduction of tax pursuant to Section 203 of the
United Kingdom Income and Corporation Taxes Act 1988 ("the Taxes Act") and
designates the Option as a UK-approved Option, the rules of the Plan shall apply
with the following modifications.

1        Delete Section 2(b) in its entirety.

2        For Section 2(h) substitute:

         " "Fair Market Value" means, for the purposes of the UK Appendix and
         any UK-Approved Option granted hereunder, on any day the closing price
         of the Common Stock on the date of calculation (or on the last
         preceding trading date if Stock was not traded on such date) if the
         Stock is listed on the New York Stock Exchange and shall otherwise be
         the market value of the Stock determined in accordance with the
         provisions of Part VIII of the United Kingdom Taxation of Chargeable
         Gains Act 1992 and agreed in advance for the purposes of the UK
         Appendix with the Shares Valuation Division of the Inland Revenue."

3        In Section 4(b) delete from "Stock dividend" in the third line to
         "event" in the fifth line and delete from "(or," in the twelfth line
         until the end of the section and insert "PROVIDED ALWAYS that no
         adjustment shall be made pursuant to this section 4(b) to a UK-Approved
         Option without the prior written approval of the Inland Revenue [and
         that sufficient unissued stock will be reserved and available to meet
         all unexercised UK-Approved Options.]

4        Insert as Section 4(c):

         "(c)     All stock obtained pursuant to the exercise of Options under a
                  UK Award will rank pari passu with other shares in the
                  Participating Company of the same class."

5        For Section 5 substitute:

         "Eligibility and Individual Limit. Only Eligible Employees (as defined
         in Section 19 of this Appendix) are eligible to be granted UK-Approved
         Options. Any UK-Approved Option shall be limited and take effect so
         that the aggregate Fair Market Value of the Stock which the Participant
         may acquire by exercise of that Option and any Stock which he may
         acquire by exercise of any other options then held by him under any
         Approved Scheme shall not exceed (pound)30,000 or such other amount as
         may be the limit imposed from time to time pursuant to paragraph 28 of
         Schedule 9. For this purpose, the Fair Market Value of Stock shall be
         calculated as at the date each option was granted or such earlier date
         as may have been agreed in writing with the Inland Revenue."


<PAGE>


6        In Section 6(a) after "additional" on the second line insert
         "objective".

7        In Section 6(b)(1) add at the end "but shall not be less than 100 per
         cent of the Fair Market Value per share of Stock on the date the Option
         is granted and must be paid in cash".

8        In Section 6(b)(2) delete from "the methods" in the second line until
         the end, [insert a full stop and then "Stock will be allotted within 30
         days of exercise".

9        In Section 6(b)(3), insert "at the date of grant" between "shall
         determine" and "the period" on the first line.

10       In Section 6(b)(4) delete from "such" on the fifth line to the end and
         substitute "there is an exchange of Options pursuant to Section 7(g).
         The Company shall notify the Participant of consummation of such
         transaction at least 10 days in advance thereof."

11       Delete Section 7(a) in its entirety.

12       Delete Section 7(d)(1) in its entirety.

13       Delete Section 7(e) in its entirety.

14       Insert as Section 7(g):

         (g)      "Exchange of Options. Pursuant to the provisions of paragraph
                  15 of Schedule 9, it is hereby provided that if any company
                  ("the Acquiring Company"):

                  (i)      obtains Control (as defined for the purposes of the
                           UK Appendix) of a company (whether or not the
                           Company) whose shares are for the time being Shares
                           for the purposes of the UK Appendix ("a Relevant
                           Company") as a result of making such an offer as is
                           referred to in sub-paragraph 15(1)(a) of Schedule 9;
                           or

                  (ii)     obtains Control (as defined for the purposes of the
                           UK Appendix) of a Relevant Company in pursuance of a
                           compromise or arrangement sanctioned by the Court
                           under Section 425 of the United Kingdom Companies Act

         (a) Subject to the terms and conditions stated herein, the Cantor

which the Cantor Parties and the eSpeed Parties do so collaborate, the
Marketplace shall be a Collaborative Marketplace and the respective authority,
responsibilities and obligations of the parties shall be governed by this
Section 3.

         (b) The parties agree that the Electronic Marketplaces that are managed
by the Cantor Parties prior to the date hereof, all of which are listed by
Product on Annex A hereto, shall be Collaborative Marketplaces governed by this
Section 3. The determination as to whether a



                                        4

<PAGE>



Marketplace that is created after the date hereof is to be a Collaborative
Marketplace governed by this Section 3 shall be made in accordance with Section
7 of this Agreement.

         (c) In the case of each Collaborative Marketplace, any Product or
Pricing Decision shall be made jointly by the Cantor Parties and the eSpeed
Parties. If the parties are unable to agree on a particular Product or Pricing
Decision after good faith efforts to do so, then the final Product or Pricing
Decision shall be made by (i) a Cantor Party, in the case of a Marketplace or
the portion thereof in which or for which a Cantor Party provides any Voice
Assisted Brokerage Services, and (ii) an eSpeed Party, in the case of a fully
electronic Marketplace (that is, a Marketplace in which no Cantor Party provides
Voice Assisted Brokerage Services) or the portion of a Marketplace that is fully
electronic; provided, however, that no Product and Pricing Decision made by an
eSpeed Party with respect to a fully electronic Marketplace shall result in the
Cantor Party's share of Transaction Revenues for the transactions effected in
the Marketplace being less than the amount necessary to cover the Cantor Party's
actual costs of providing Cantor Services in connection with such Marketplace.

         (d) In the case of each Collaborative Marketplace, the applicable
eSpeed Party (i) shall own and operate the Electronic Trading System associated
with the Electronic Marketplace, (ii) shall be responsible, as between the
parties, for the provision of Electronic Brokerage Services to customers and
(iii) except as provided above with respect to Product or Pricing Decisions,
shall have reasonable discretion as to the manner and means of operating the
Electronic Trading System and providing Electronic Brokerage Services to
customers and Cantor brokers in connection therewith.

         (e) In the case of each Collaborative Marketplace, the applicable
Cantor Party (i) shall be responsible, as between the parties, for the provision
of Cantor Services to customers and (ii) except as provided above with respect
to Product or Pricing Decisions, shall have reasonable discretion as to the
manner and means of providing the Cantor Services. The applicable Cantor Party
shall be responsible for maintenance of books and records and compliance with
applicable securities laws, rules and regulations, as determined by the
applicable Cantor Party. CFP and CF & Co shall be responsible for compliance
with the reporting requirements under Regulation ATS and related provisions of
the Securities Exchange Act of 1934, as amended. In that regard, CFP and CF & Co
each will be the broker for all transactions in the respective matching systems,
and each will determine the various non-discretionary parameters under which
transactions match in their respective systems. eSpeed Securities and eSpeed GS
shall cooperate with CFP and CF & Co in all regulatory compliance matters and,
if applicable, in complying with Regulation ATS.

         (f) Without limiting the authority of the parties in their respective
areas of responsibility pursuant to paragraphs (d) and (e), the parties
recognize the importance of providing an integrated and seamless service to
customers. Accordingly, the parties shall consult diligently and in good faith,
as and as often as necessary, to ensure that their respective services are
properly integrated.

         (g) All information and data, other than Information, created,
developed, used in connection with or relating to the operation of and effecting
of transactions in any Marketplace ("Data") shall constitute the sole property
of the Cantor Parties or the eSpeed Parties, as applicable, on the following
basis: (i) if the Data relate to Financial Products, the Data shall belong
solely to the Cantor Parties, (ii) if the Data relate to a Collaborative
Marketplace in which only Products that are



                                        5

<PAGE>



not Financial Products are traded, the ownership of the Data shall be determined
by the Cantor Parties and the eSpeed Parties on a case-by-case basis based on
good faith negotiations, (iii) if the Data relate to an eSpeed Marketplace in
which only Products that are not Financial Products are traded, the Data shall
belong solely to the eSpeed Parties and (iv) if the Data relate to a
non-Collaborative Marketplace that is not an eSpeed Marketplace and in which
Financial Products are traded, the Data shall belong solely to the Cantor
Parties. All Information relating to Financial Products transmitted and
disseminated on or through the Electronic Marketplace shall be the sole property
of the Cantor Parties and, as between the parties, the Cantor Parties shall have
the sole and exclusive right to use, publish and be compensated for Information
Services in connection with or relating to such Information; provided, however,
in the case of each Collaborative Marketplace, that the eSpeed Parties shall
have the right (without any obligation to pay the Cantor Parties therefor) to
use such Information in connection with the execution of transactions in the
applicable Collaborative Marketplace.

         (h) To such extent as is consistent with the Cantor Parties' own
businesses of providing Electronic Brokerage Services in Marketplaces that are
not Collaborative Marketplaces, the Cantor Parties shall promote and market
eSpeed Marketplaces for effecting transactions in Financial Products, and shall
refer customers and prospective customers to the applicable eSpeed Parties in an
effort to cause such customers to effect transactions in Financial Products in
eSpeed Marketplaces.

         4. Sharing of Transaction Revenues. The Cantor Parties and the eSpeed
Parties agree to share Transaction Revenues with regard to transactions effected
through Marketplaces in the following manner:

         (a) If (i) the Electronic Marketplace is a Collaborative Marketplace,
(ii) the transaction relates to a Financial Product (other than a Financial
Product that is traded on the Cantor Exchange) and (iii) no Cantor Party
provides Voice Assisted Brokerage Services in connection with the transaction to
which the Transaction Revenues relate (that is, the transaction is fully
electronic), then the applicable eSpeed Party will receive the aggregate
Transaction Revenues and will pay to the applicable Cantor Party a service fee
equal to 35% of the Transaction Revenues.

         (b) If (i) the Electronic Marketplace is a Collaborative Marketplace,
(ii) the transaction relates to a Financial Product (other than a Financial
Product that is traded on the Cantor Exchange) and (iii) a Cantor Party provides
Voice Assisted Brokerage Services in connection with the transaction to which
the Transaction Revenues relate, then the applicable Cantor Party will receive
the aggregate Transaction Revenues and will pay to the applicable eSpeed Party a
service fee equal to 7% of the Transaction Revenues.

         (c) If (i) the Electronic Marketplace is a Collaborative Marketplace,
(ii) the transaction relates to a Product that is traded on the Cantor Exchange
and (iii) no Cantor Party provides Voice Assisted Brokerage Services in
connection with the transaction to which the Transaction Revenues relate (that
is, the transaction is fully electronic), then the applicable eSpeed Party will
receive the aggregate Transaction Revenues and will pay to the applicable Cantor
Party a service fee equal to 20% of the Transaction Revenues.




                                        6

<PAGE>



         (d) If (i) the Electronic Marketplace is a Collaborative Marketplace,
(ii) the transaction relates to a Product that is traded on the Cantor Exchange
and (iii) a Cantor Party provides Voice Assisted Brokerage Services in
connection with the transaction to which the Transaction Revenues relate, then
the applicable eSpeed Party will receive the aggregate Transaction Revenues and
will pay to the applicable Cantor Party a service fee equal to 55% of the
Transaction Revenues.

         (e) If (i) the Electronic Marketplace is a Collaborative Marketplace
and (ii) the transaction relates to a Product that (x) is not a Financial
Product and (y) is not traded on the Cantor Exchange, then the applicable Cantor
Party and the applicable eSpeed Party will share Transaction Revenues in such
manner as they shall agree.

         (f) If (i) the Electronic Marketplace is an eSpeed Marketplace and (ii)
the transaction relates to a Financial Product, then the applicable eSpeed Party
will receive the aggregate Transaction Revenues and will pay to CFLP a service
fee equal to 20% of the Transaction Revenues.

         (g) If (i) the Electronic Marketplace is an eSpeed Marketplace and (ii)
the transaction relates to a Product other than a Financial Product, then the
applicable eSpeed Party will receive and retain all of the Transaction Revenues.

         (h) If (i) a transaction is effected in an Electronic Marketplace that
is not a Collaborative Marketplace and is not an eSpeed Marketplace, but that is
a Marketplace in which Cantor provides Electronic Brokerage Services, and (ii)
the transaction relates to a Financial Product, then the applicable Cantor Party
will receive the aggregate Transaction Revenues and pay to eSpeed a service fee
equal to 30% of the amount eSpeed would have received pursuant to Section 4 (a)
or 4 (b) of this Agreement if the Marketplace had been a Collaborative
Marketplace. For purposes of this paragraph (h), the Transaction Revenues shall
be reduced by the costs incurred or paid by a Cantor Party to a third party to
provide or arrange for the provision of Electronic Brokerage Services.

         (i) If a transaction (i) is not effected through an Electronic
Marketplace, but (ii) is electronically assisted (by way of example, but not
limited to, a screen-assisted open outcry transaction), then the applicable
Cantor Party will receive the aggregate Transaction Revenues and will pay to the
applicable eSpeed Party 2.5% of the Transaction Revenues.

         (j) Notwithstanding the foregoing, in the event that a Cantor Party's
direct costs payable to third parties (other than the Cantor Parties and their
affiliates) for providing Clearance, Settlement and Fulfillment Services with
respect to transactions in a Collaborative Marketplace with respect to any
Financial Product for any month exceed the direct costs incurred by the Cantor
Parties to clear and settle cash transactions in United States Treasury
securities for such month, the cost of such excess shall be borne pro rata by
the applicable Cantor Party and the applicable eSpeed Party in the same
proportion as the Transaction Revenues and service fees for such transactions
are to be shared.

         (k) For any month, for any Product for which sales and purchases during
such month are effected both through fully electronic transactions and through
voice-brokered transactions, Transaction Revenues earned with respect to such
Product shall be allocated between fully electronic transactions and
voice-brokered transactions as follows: the amount of Transaction Revenues



                                        7

<PAGE>



attributable to fully electronic transactions or voice-brokered transactions, as
the case may be, for such Product during such month in a Marketplace shall be
equal to (x) total Transaction Revenues for such Product for such month in such
Marketplace multiplied by (y) a fraction, the numerator of which is the notional
volume (by currency) of all transactions in such specific Product type for such
month in such Marketplace effected by fully electronic transactions or
voice-brokered transactions, as the case may be, and the denominator of which is
the notional volume (by currency) of all transactions in such specific Product
type for such month in such Marketplace.

         (l) In the event that a customer does not pay, or pays only a portion
of, the Transaction Revenues relating to a transaction described in paragraphs
(a) through (i) above (a "Loss Event"), then the relevant Cantor Party and the
relevant eSpeed Party each shall bear its respective share of the loss arising
from the Loss Event in the same proportion as the Transaction Revenues and
service fees for such transaction are to be shared.

         (m) All amounts due and payable to a Cantor Party or an eSpeed Party by
the other pursuant to this Section 4 shall be paid in the manner specified in
Section 12 of this Agreement.

         (n) In the event that any tax is imposed on Transaction Revenues with
respect to a transaction (other than a Tax on net income), the cost of such tax
will be borne by the applicable eSpeed Party and the applicable Cantor Party in
the same proportion as the Transaction Revenues and service fees for such
transaction are to be shared.

         5. Ancillary IT Services.

         (a) During the Term, the eSpeed Parties shall provide Ancillary IT
Services to the Cantor Parties.

         (b) CFLP shall pay to eSpeed in consideration for the Ancillary IT
Services an amount equal to the direct and indirect costs, including overhead,
that the eSpeed Parties incur in performing those services.

         6. Representations and Warranties.

                  (b)      Authority; Binding Effect; No Conflicts.

                  (i) Each Executing Cantor Party has taken all necessary
         actions to authorize the execution and delivery of this Agreement and
         to perform all of its obligations under, and to consummate the
         transactions contemplated by, this Agreement. This Agreement has been
         duly and validly executed by each of the Executing Cantor Parties. This
         Agreement constitutes the valid and binding obligation of each of the
         Executing Cantor Parties enforceable against each of the Executing
         Cantor Parties in accordance with its terms, subject to the effect of
         reorganization, bankruptcy, insolvency, moratorium, fraudulent
         conveyance and other similar laws relating to or affecting creditors'
         rights generally and court decisions with respect thereto, and subject
         to the application of equitable principles and the discretion of the
         court (regardless of whether the enforceability is considered in a
         proceeding in equity or at law). The execution, delivery and
         performance by each of the Executing Cantor Parties of this Agreement
         shall not, with or without the giving of notice or the lapse of time or
         both, (x) violate any provision of any federal, state, local or foreign
         law, statute, rule or regulation to which any of the Executing Cantor
         Parties is subject, (y) violate any injunction, order, judgment,
         ruling, decree or settlement applicable to any of the Executing Cantor
         Parties or (z) conflict with, or result in a breach or violation of,
         any provision of the certificate of incorporation, by-laws, partnership
         agreement or similar governing document of any of the Executing Cantor
         Parties or any lease, contract, agreement, instrument, undertaking or
         covenant by which any of the Executing Cantor Parties is bound.

                  (ii) Each of the Executing eSpeed Parties has taken all
         necessary corporate actions to authorize, execute and deliver this
         Agreement and to perform all of its obligations under, and to
         consummate the transactions contemplated by, this Agreement. This
         Agreement has been duly and validly executed by each of the Executing
         eSpeed Parties. This Agreement constitutes the valid and binding
         obligation of each of the Executing eSpeed Parties enforceable against
         each of the Executing eSpeed Parties in accordance with its terms,
         subject to the effect of reorganization, bankruptcy, insolvency,
         moratorium, reorganization, fraudulent conveyance and other similar
         laws relating to or affecting creditors' rights generally and court
         decisions with respect thereto, and subject to the application of
         equitable principles and the discretion of the court (regardless of
         whether the enforceability is considered in a proceeding in equity or
         at law). The execution, delivery and performance by each of the
         Executing eSpeed Parties of this Agreement and the consummation by each
         of the Executing eSpeed Parties of the transactions contemplated hereby
         will not, with or without the giving of notice or the lapse of time or
         both, (x) violate any provision of any federal, state or local law,
         statute, rule or regulation to which any of the Executing eSpeed
         Parties is subject, (y) violate any injunction, order, judgment,
         ruling, decree or settlement applicable to any of the Executing eSpeed
         Parties, or (z) conflict with, or result in a breach or violation of,

         the Executing eSpeed Parties or any lease, contract, agreement,
         instrument, undertaking or covenant by which any of the Executing
         eSpeed Parties is bound.

                  (c) Litigation; No Undisclosed Liabilities. Except as
disclosed in the Prospectus relating to eSpeed's initial public offering, there
is no litigation pending or, to CFLP's knowledge,




                                        9

threatened,  which questions the validity or enforceability of this Agreement or
seeks to enjoin the consummation of any of the transactions contemplated hereby.

         7.       New Marketplaces; Non-competition; Strategic Alliances.

                  (a) If a Cantor Party wishes to create a new Marketplace for a
Financial Product, then such Cantor Party may, by providing a New Market Notice
to eSpeed, require eSpeed to provide, or cause another eSpeed Party to provide,
Electronic Brokerage Services with respect to that Marketplace. In such a case,
eSpeed shall use commercially reasonable efforts to develop an Electronic
Trading System for, and to render Electronic Brokerage Services with respect to,
that Marketplace under the terms of this Agreement. If eSpeed is able to develop
and put into operation an Electronic Trading System for the Marketplace within
180 days, then the Marketplace shall be a Collaborative Marketplace and the
operation thereof shall be subject to the provisions of Section 3 of this
Agreement. If, after diligent effort, eSpeed is unable to develop and put into
operation an Electronic Trading System for the Marketplace within 180 days, then
(i) eSpeed shall have no liability to any Cantor Party for its failure to
provide an Electronic Trading System, (ii) the Cantor Party may create and
operate the Marketplace in any manner that the Cantor Party deems to be
acceptable and (iii) the Marketplace shall not be a Collaborative Marketplace.
CFLP agrees that its proposal to create a new Marketplace and the requirements
relating thereto will be commercially reasonable in scope and that CFLP or
another Cantor Party will diligently pursue the development of such Marketplace
in a meaningful way and that failure to do so within two years of the provision
of the New Market Notice will cause any rights of the eSpeed Parties and the
Cantor Parties in this Section 7 and Section 8 of this Agreement to revert to
their original status.

                  (b) If a Cantor Party wishes to create a new Marketplace for a
Financial Product that will involve the provision of Electronic Brokerage
Services and the Cantor Party does not require eSpeed to operate an Electronic
Trading System and to provide Electronic Brokerage Services for that Marketplace
pursuant to paragraph (a) of this Section 7, then the Cantor Party shall provide
to eSpeed a New Market Notice relating thereto and eSpeed shall have a right of
first refusal to provide Electronic Brokerage Services with respect to that
Marketplace under the terms of this Agreement. If eSpeed notifies the Cantor
Party that it wishes to provide Electronic Brokerage Services with respect to
the new Marketplace, then eSpeed shall use commercially reasonable efforts to
develop and put into operation an Electronic Trading System for the Marketplace
within 180 days. If eSpeed is able to develop and put into operation an
Electronic Trading System for the Marketplace within 180 days, then the
Marketplace shall be a Collaborative Marketplace and the operation thereof shall
be subject to Section 3 of this Agreement. If, after diligent effort, eSpeed is
unable to develop and put into operation an Electronic Trading System for the
Marketplace within 180 days, or eSpeed notifies the Cantor Party that it does
not wish to provide Electronic Brokerage Services with respect to the new
Marketplace, then (i) the applicable Cantor Party may provide or obtain from a
third party Electronic Brokerage Services for that Marketplace in any manner
that the Cantor Party deems to be acceptable and (ii) the Marketplace shall not
be a Collaborative Marketplace. CFLP agrees that its proposal to create a new
Marketplace and the requirements relating thereto will be commercially
reasonable in scope and that CFLP or another Cantor Party will diligently pursue
the development of such Marketplace in a meaningful way and that failure to do
so within two years of the provision of the New Market Notice will cause any
rights of the eSpeed Parties and the Cantor Parties in this Section 7 and
Section 8 of this Agreement to revert to their original status.

                  (c) If a Cantor Party wishes to create a new Electronic
Marketplace for a Product that is not a Financial Product, then the Cantor Party
shall provide to eSpeed a New Market Notice relating thereto. eSpeed or another
eSpeed Party shall have the opportunity to offer to provide Electronic Brokerage
Services with respect to the new Marketplace, which offer the Cantor Party shall
review and negotiate in good faith, but may accept or reject in its reasonable
discretion. If the Cantor Party accepts the eSpeed Party's negotiated terms of
proposed offer to provide Electronic Brokerage Services, then the Marketplace
shall be a Collaborative Marketplace and the operation thereof shall be subject
to Section 3 of this Agreement on such terms as the applicable Cantor Party and
the applicable eSpeed Party shall agree. If the Cantor Party rejects the eSpeed
Party's negotiated terms of proposed offer to provide Electronic Brokerage
Services, then (i) the Marketplace shall not be a Collaborative Marketplace and
(ii) the Cantor Party may create and operate the Marketplace in any manner that
the Cantor Party deems to be acceptable.

                  (d) If an eSpeed Party wishes to create a new Electronic
Marketplace for a Financial Product, then the eSpeed Party shall provide to CFLP
a New Market Notice relating thereto and CFLP or another Cantor Party shall have
a right of first refusal to provide the applicable Cantor Services with respect
to that Marketplace under the terms of this Agreement. If, within 30 days of
receiving the New Market Notice, CFLP or another Cantor Party notifies the
eSpeed Party that it wishes to provide such Cantor Services with respect to the
new Marketplace, then the Marketplace shall be a Collaborative Marketplace and
the operation thereof shall be subject to Section 3 of this Agreement. If (i)
CFLP notifies the eSpeed Party that it does not wish to provide such Cantor
Services or (ii) CFLP fails to notify the eSpeed Party within the 30-day time
period that it wishes to provide such Cantor Services with respect to the new
Marketplace, then the eSpeed Party may provide or obtain from a third party
those services for that Marketplace in any manner that the eSpeed Party deems to
be acceptable, and the Marketplace shall be an eSpeed Marketplace for purposes
of this Agreement.

                  (e) If an eSpeed Party wishes to create a new Electronic
Marketplace for a Product that is not a Financial Product, then the eSpeed Party
shall provide to CFLP a New Market Notice relating thereto. CFLP or another
Cantor Party shall have the opportunity to offer to provide Cantor Services with
respect to the new Marketplace if, within 30 days of receiving the New Market
Notice, CFLP or another Cantor Party notifies the eSpeed Party that it wishes to
provide such Cantor Services with respect to the new Marketplace. The eSpeed
Party shall review and negotiate the offer of CFLP or the other CFLP Party in
good faith, but may accept or reject that offer in its reasonable discretion. If
the eSpeed Party accepts a Cantor Party's negotiated terms of proposed offer to
provide Cantor Services, then the Marketplace shall be a Collaborative
Marketplace and the operation thereof shall be subject to Section 3 of this
Agreement on such terms as the applicable Cantor Party and the applicable eSpeed
Party shall agree. If the eSpeed Party rejects the Cantor Party's negotiated
terms of proposed offer to provide Cantor Services, then (i) the Marketplace
shall not be a Collaborative Marketplace and (ii) the eSpeed Party may create
and operate the Marketplace in any manner that the eSpeed Party deems to be
acceptable.

                  (f) No eSpeed Party shall, directly, indirectly or in
connection with a third Person, engage in any activities competitive with a
business activity now or hereafter conducted by a Cantor Party or provide or
assist any other Person in providing any Cantor Service, other than (i) in


                                       11

<PAGE>



collaboration with a Cantor Party pursuant to Section 3 of this Agreement, (ii)
with respect to a new Marketplace involving a Financial Product, after CFLP (x)
has indicated that it is unable or unwilling to provide such Cantor Service or
(y) fails to indicate to the eSpeed Party within the prescribed 30-day period
that it does wish to provide such Cantor Service with respect to that
Marketplace in accordance with paragraph (d) of this Section 7, (iii) with
respect to a new Marketplace involving a Product that is not a Financial Product
in accordance with paragraph (c) or paragraph (e) of this Section 7 or (iv) with
respect to an Unrelated Dealer Business in which an eSpeed Party develops and
operates a fully electronic Marketplace.


                  (g) No Cantor Party shall, directly, indirectly or in
connection with a third Person, provide or assist any other Person in providing
Electronic Brokerage Services, other than (i) in collaboration with eSpeed
pursuant to Section 3 of this Agreement, (ii) with respect to a new Marketplace,
after eSpeed (x) has indicated that it is unable to develop and put into
operation an Electronic Trading System with respect to that new Marketplace in
accordance with paragraph (a) of this Section 7 or (y) has declined to exercise
its right of first refusal or is unable to develop and put into operation an
Electronic Trading System with respect to that new Marketplace in accordance
with paragraph (b) of this Section 7, including, without limitation, the time
period specified therein, or (iii) with respect to an Unrelated Dealer Business.

                  (h) Notwithstanding the foregoing and anything to the contrary
in this Section 7, the Unrelated Dealer Businesses are expressly excluded from
eSpeed's rights of first refusal under paragraph (b) and the conduct by any
Cantor Party either directly, or indirectly with or through another Person, of
any of the Unrelated Dealer Businesses shall not be deemed to be a violation of
this Section 7.

                  (i) The Cantor Parties and the eSpeed Parties shall be
entitled to and may enter into strategic alliances, joint ventures, partnerships
or similar arrangements with Persons and consummate Business Combinations with
Persons (all of the foregoing, collectively, "Alliance Opportunities") on the
following basis only. If an Alliance Opportunity (i) relates to a Person that
directly or indirectly provides Cantor Services and engages in business
operations that do not involve Electronic Brokerage Services, then any Cantor
Party shall be entitled to consummate a transaction with respect to such an
Alliance Opportunity, (ii) relates to a Person that directly or indirectly
provides Electronic Brokerage Services and engages in business operation that do
not involve any Cantor Service, then any eSpeed Party shall be entitled to
consummate a transaction with respect to such an Alliance Opportunity and (iii)
is an Alliance Opportunity with respect to a Person other than those described
in clauses (i) and (ii) above, then the Cantor Parties and the eSpeed Parties
shall cooperate to jointly pursue and consummate a transaction with respect to
such Alliance Opportunity on mutually agreeable terms. For purposes of this
paragraph, a "Business Combination" shall mean, with respect to any Person, a
transaction initiated by and/or in which a Cantor Party or an eSpeed Party is
the acquiror involving (i) a merger, consolidation, amalgamation or combination,
(ii) any sale, dividend, split or other disposition of any capital stock or
other equity interests (or securities convertible into or exchangeable for or
options or warrants to purchase any capital stock or other equity equivalents)
of the Person, (iii) any tender offer (including without limitation a
self-tender), exchange offer, recapitalization, liquidation, dissolution or
similar transaction, (iv) any sale, dividend or other disposition of a
significant portion of the assets and properties of the Person (even if less
than


                                       12

<PAGE>



all or substantially all of such assets or properties), and (v) entering into of
any agreement or understanding, or the granting of any rights or options, with
respect to any of the foregoing.

                  8. Exclusive Patent Licenses.

                  (a) Subject to the second following sentence, CFLP and CFPH
hereby grant to eSpeed an exclusive, perpetual, irrevocable, worldwide,
royalty-free right and license, with the right to sublicense to its subsidiaries
and affiliates, under all patents and patent applications of CFLP and CFPH
related to Electronic Marketplaces, now known and existing, including all
provisionals, divisionals, continuations, continuations-in-part, reissues and
extensions derived therefrom, as well as all foreign patents and patent
applications now known or pending and other counterparts thereof (the "Patent
Rights"). The Cantor Parties agree to take all commercially reasonable actions
requested by the eSpeed Parties, at the sole expense of the eSpeed Parties, to
cause the Patent Rights to remain in full force and effect to the extent
permitted by law. In the event that eSpeed (x) has indicated that it is unable
to develop and put into operation an Electronic Trading System with respect to a
new Marketplace in accordance with paragraph (a) of Section 7 or (y) has
declined to exercise its right of first refusal with respect to a new
Marketplace in accordance with paragraph (b) of Section 7, then the Cantor
Parties shall have a limited right to use the Patent Rights solely in connection
with the operation of that new Marketplace. The Cantor Parties shall cooperate
with eSpeed, at eSpeed's sole expense, in any attempt by eSpeed to prevent or
otherwise seek remedies or damages which, in any case, shall inure to eSpeed for
any third party infringement of the Patent Rights that are the subject of the
license granted to eSpeed pursuant to this Section 8 or to defend against any
third party claim relating to the Patent Rights.

                  (b) CFS hereby grants to eSpeed a non-exclusive, perpetual,
irrevocable, worldwide, royalty-free right and license, with the right to
sublicense to its subsidiaries and affiliates, to use the trademarks "Cantor
Exchange," "Interactive Matching," and "CX" (collectively, the "Trademark
Rights"), in all media now known or hereinafter developed, in connection with
Electronic Marketplaces. The Cantor Parties agree to take all commercially
reasonable actions requested by the eSpeed Parties, at the sole expense of the
eSpeed Parties, to cause the Trademark Rights to remain in full force and effect
to the extent permitted by law. The eSpeed Parties acknowledge that CFS owns the
Trademark Rights, including all goodwill now or hereafter associated therewith,
and that all goodwill and improved reputation generated by the eSpeed Parties'
use of the Trademark Rights shall inure to the benefit of CFS. In order to
preserve the inherent value of the Trademark Rights, the eSpeed Parties agree to
use reasonable efforts to ensure that the products and services in connection
with which the eSpeed Parties use the Trademark Rights shall be at least equal
to the standard prevailing in the operation of the Electronic Marketplaces
immediately prior to the date of the Agreement.

                  9. Indemnification.

                  (a) CFLP's Indemnification Obligations. Subject to the terms
and conditions of this Section 9, CFLP agrees to defend, indemnify and hold
eSpeed, the other eSpeed Parties and their respective officers, directors,
affiliates, agents, attorneys, employees and representatives harmless from and
against any and all liabilities, losses, costs, damages, expenses, penalties,
fines and taxes, including,



                                       13

<PAGE>



without limitation, reasonable legal and other expenses (collectively,
"Damages"), directly or indirectly arising out of, resulting from or relating
to:

                           (i) any breach of any covenant, agreement or
         obligation of any Cantor Party contained in this Agreement; and

                           (ii) any liability resulting from CFLP broker errors
         and errors arising in connection with the provision by any Cantor Party
         of Clearance, Settlement and Fulfillment Services.

                  (b) eSpeed's Indemnification Obligations. Subject to the terms
and  conditions of this Section 9, eSpeed  agrees to defend,  indemnify and hold
CFLP,  the other  Cantor  Parties  and  their  respective  officers,  directors,
affiliates,  agents, attorneys,  employees and representatives harmless from and
against any and all Damages  directly or  indirectly  arising out of,  resulting
from or relating to:

                           (i) any breach of any covenant, agreement or
         obligation of any eSpeed Party contained in this Agreement;

                           (ii) any liability resulting from failures of
         eSpeed's technology and errors caused by the technology of the
         Electronic Marketplaces; and

                           (iii) any liability resulting from any claims
         asserted against Cantor with respect to an eSpeed Party's exercise of
         its Patent Rights.

                  (c) Claims for Indemnification; Defense of Indemnified Claims.
For purposes of this Section, the party entitled to indemnification shall be
referred to as the "Indemnified Party" and the party required to indemnify shall
be referred to as the "Indemnifying Party." In the event that the Indemnifying
Party shall be obligated to the Indemnified Party pursuant to this Section 9 or
in the event that a suit, action, investigation, claim or proceeding is begun,
made or instituted as a result of which the Indemnifying Party may become
obligated to the Indemnified Party hereunder, the Indemnified Party shall give
prompt written notice to the Indemnifying Party of the occurrence of such event,
specifying the basis for such claim or demand, and the amount or estimated
amount thereof to the extent then determinable (which estimate shall not be
conclusive of the final amount of such claim or demand); provided, however, that
the failure to give such notice shall not constitute a waiver of the right to
indemnification hereunder unless the Indemnifying Party is actually prejudiced
in a material respect thereby. The Indemnifying Party agrees to defend, contest
or otherwise protect the Indemnified Party against any such suit, action,
investigation, claim or proceeding at the Indemnifying Party's own cost and
expense with counsel of its own choice, who shall be, however, reasonably
acceptable to the Indemnified Party. The Indemnifying Party may not make any
compromise or settlement without the prior written consent of the Indemnified
Party (which will not be unreasonably withheld or delayed) and the Indemnified
Party shall receive a full and unconditional release reasonably satisfactory to
it pursuant to such compromise or settlement. The Indemnified Party shall have
the right but not the obligation to participate at its own expense in the
defense thereof by counsel of its own choice. If requested by the Indemnifying
Party, the Indemnified Party shall (at the Indemnifying Party's expense) (i)
cooperate with the Indemnifying Party and its counsel in contesting any claim or
demand which the Indemnifying Party defends, (ii) provide the Indemnifying



                                       14

<PAGE>



Party with reasonable access during normal business hours to its books and
records to the extent they relate to the condition or operation of a Marketplace
and are requested by the Indemnifying Party to perform its indemnification
obligations hereunder, and to make copies of such books and records, and (iii)
make personnel available to assist in locating any books and records relating to
a Marketplace or whose assistance, participation or testimony is reasonably
required in anticipation of, preparation for or the prosecution and defense of,
any claim subject to this Section 9. In the event that the Indemnifying Party
fails timely to defend, contest or otherwise protect the Indemnified Party
against any such suit, action, investigation, claim or proceeding, the
Indemnified Party shall have the right to defend, contest or otherwise protect
the Indemnified Party against the same and may make any compromise or settlement
thereof and recover the entire cost thereof from the Indemnifying Party,
including, without limitation, reasonable attorneys' fees, disbursements and all
amounts paid as a result of such suit, action, investigation, claim or
proceeding or compromise or settlement thereof.

                  (d) Payments; Non-Exclusivity. Any amounts due an Indemnified
Party under this Section 9 shall be due and payable by the Indemnifying Party
within fifteen (15) business days after (x) in the case of a claim which does
not involve any third party, receipt of written demand therefor and (y) in the
case of a claim which involves a third party, the final disposition of such
claim or demand, provided that reasonable legal and other out-of-pocket costs
and expenses are reimbursed currently within 15 business days after demand
therefor. The remedies conferred in this Section 9 are intended to be without
prejudice to any other rights or remedies available at law or equity to the
Indemnified Parties, now or hereafter.

         10. Relationship of the Parties. The relationship of the Cantor Parties
on the one hand and the eSpeed Parties on the other hand is that of independent
contractors. Pursuant to this Agreement, the Cantor Parties and the eSpeed
Parties intend to render separate but related services to customers and to
divide certain of the revenues arising from those services, but the parties do
not intend to share profits or losses or to enter into or create any
partnership, and no partnership or other like arrangement shall be deemed to be
created hereby. None of the Cantor Parties or eSpeed Parties shall have any
claim against the others or right of contribution with respect to any uninsured
loss incurred by any of them nor shall any of them have a claim or right against
the others with respect to any loss that is deemed to be included within the
deductible, retention or self-insured portion of any insured risk.

         11. Audit. eSpeed may request a review, by those certified public
accountants who examine CFLP's books and records, of CFLP's allocation of
Transaction Revenues to eSpeed to determine whether such allocation was based
upon the procedures set forth herein. Such a review is to be conducted at
eSpeed's expense. CFLP may request a review, by those certified public
accountants who examine eSpeed's books and records, of eSpeed's allocation of
Transaction Revenues to CFLP to determine whether such allocation was based upon
the procedures set forth herein. Such a review is to be conducted at CFLP's
expense.

         12. Invoicing and Billing; Payment of Service Fees. Each of eSpeed and
CFLP shall pay to the other, within 30 days of the end of each calendar month,
the amounts due and received to the Cantor Parties or the eSpeed Parties, as the
case may be (determined in the manner provided in Section 4 of this Agreement),
during that calendar month. eSpeed shall invoice CFLP for charges for Ancillary
IT Services provided pursuant hereto on a monthly basis as incurred, such
invoices to be



                                       15

<PAGE>



delivered to CFLP by eSpeed within 15 days after the end of each calendar month.
CFLP shall pay to eSpeed the aggregate charge for Ancillary IT Services provided
under this Agreement in arrears within 30 days after the end of each calendar
month. Amounts due by one party to another under this Agreement shall be settled
against amounts due by the second party to the first under this or any other
agreement. All payments to be made pursuant to this Agreement shall be exclusive
of United Kingdom Value Added Tax which, if applicable to any payments
hereunder, shall be added to the amount of, and be paid in addition to, such
payments.

         13. Documentation. All Transaction Revenues, service fees, fees for
Ancillary IT services and other benefits hereunder shall be substantiated by and
payments thereof shall be preceded or accompanied by, as applicable, appropriate
schedules, invoices or other documentation.

         14. Force Majeure. Any failure or omission by a party in the
performance of any obligation under this Agreement shall not be deemed a breach
of this Agreement or create any liability if the same arises from any cause or
causes beyond the control of such party, including, but not limited to, the
following, which, for purposes of this Agreement shall be regarded as beyond the
control of each of the parties hereto: acts of God, fire, storm, flood,

                  (a) This Agreement and all the covenants herein contained
shall be binding upon the parties hereto, their respective heirs, successors,
legal representatives and assigns. No party shall have the right to assign all
or any portion of its rights, obligations or interests in this Agreement or any
monies which may be due pursuant hereto without the prior written consent of the
other affected parties and which consent may not be unreasonably withheld.

and/or waiver hereof or hereunder must be approved by a majority of the outside

and supersedes any and all prior written or oral contracts or negotiations
between the parties with respect to the subject matter hereof.

                  (d) This Agreement shall be strictly construed as independent
from any other agreement or relationship between the parties.

                  (e) This Agreement is made pursuant to and shall be governed
and construed in accordance with the laws of the State of New York, without
regard to the principles of conflict of laws thereof.
