PROXY STATEMENT

This Proxy Statement is being furnished in connection with the solicitation of Proxies by and on behalf of our Board of Directors to be used at our Annual Meeting of Stockholders to be held on Thursday, October 26, 2000, and at any adjournment thereof (the "Annual Meeting"), for the purposes set forth in the accompanying Notice of Annual Meeting. Our Annual Report for the fiscal year ended December 31, 1999 accompanies this Proxy Statement. This Proxy Statement and accompanying materials are expected to be first sent or given to our stockholders on or about September 22, 2000.

The close of business on September 18, 2000 has been fixed as the record date (the "Record Date") for the determination of the stockholders entitled to notice of and to vote at the Annual Meeting. Only holders of record as of that date of shares of our Class A Common Stock, $.01 par value per share (the "Class A Common Stock"), or of our Class B Common Stock, $.01 par value per share (the "Class B Common Stock"), are entitled to notice of and to vote at the Annual Meeting. The Class A Common Stock and the Class B Common Stock are sometimes collectively referred to herein as the "Common Equity."

Each share of the Class A Common Stock entitles the holder thereof to one vote per share on each matter presented to the stockholders for approval at the Annual Meeting. Each share of the Class B Common Stock entitles the holder thereof to ten votes per share on each matter presented to the stockholders for approval at the Annual Meeting. On September 1, 2000, there were 16,160,238 shares of the Class A Common Stock and 35,685,581 shares of the Class B Common Stock, for a total of 51,845,819 shares of the Common Equity, outstanding and entitled to vote.

Execution of a Proxy by a stockholder will not affect such stockholder's right to attend the Annual Meeting and to vote in person. Any stockholder who executes a Proxy has a right to revoke it at any time before it is voted by advising Stephen M. Merkel, our Secretary, in writing of such revocation, by executing a later-dated Proxy which is presented to us at or prior to the Annual Meeting, or by appearing at the Annual Meeting and voting in person. Attendance at the Annual Meeting will not in and of itself constitute revocation of a Proxy. We have retained D.F. King & Co., Inc. to assist in the solicitation of Proxies.

The required quorum for the transaction of business at the Annual Meeting is a majority of the collective voting power represented by the shares of the Common Equity issued and outstanding on the Record Date (the "Total Voting Power"), which shares must be present in person or represented by Proxy at the Annual Meeting. Assuming a quorum, the nominees receiving a plurality of the Total Voting Power present in person or by Proxy at the Annual Meeting and entitled to vote on the election of directors will be elected as directors. The proposal to approve an additional investment right in the Class A Common Stock by Williams Energy Marketing & Trading Company ("WEM&T") and Dynegy, Inc. ("Dynegy") (together, the "Additional Investment Right") requires the affirmative vote of a majority of the Total Voting Power present in person or by Proxy at the Annual Meeting and entitled to vote on such proposal.

With regard to the election of directors, votes may be cast in favor or withheld; votes that are withheld will be counted for purposes of determining the presence or absence of a quorum but will have no other effect. With regard to the proposal to approve the Additional Investment Right, stockholders may vote in favor of or against such proposal, or they may abstain. Abstentions will be counted for purposes of determining the presence or absence of a quorum and will have the same effect as a vote against the proposal to approve the Additional Investment Right. Broker non-votes, if any, will be counted for purposes of determining the presence or absence of a quorum, but will have no effect on the election of directors or the proposal to approve the Additional Investment Right.

Unless specified otherwise, the Proxies will be voted FOR the election of all the nominees to serve as our directors until the next annual meeting and until their successors are duly elected and qualified and FOR the approval of the Additional Investment Right. In the discretion of the Proxy holders, the Proxies will also be voted for or against such other matters as may properly come before the Annual Meeting. Management is not aware of any other matters to be presented for action at the Annual Meeting.

Our principal executive offices are located at One World Trade Center, 103rd Floor, New York, NY 10048, and our telephone number there is (212) 938-3773.

PROPOSAL 1 -- ELECTION OF DIRECTORS

Our Board of Directors is comprised of seven members. The names of the seven nominees for election as directors are set forth below. All of the nominees are to be elected at the Annual Meeting and until their successors are duly elected and qualified. All of the nominees listed below are expected to serve as directors if they are elected. If any nominee should decline or be unable to accept such nomination or to serve as a director (an event which our Board of Directors does not now expect), our Board of Directors reserves the right to nominate another person or to vote to reduce the size of our Board of Directors. In the event another person is nominated, the Proxy holders intend to vote the shares to which the Proxy relates for the election of the person nominated by our Board of Directors. There is no cumulative voting for directors.

Compensation Committee Interlock and Insider Participation

The Compensation Committee of our Board of Directors consists of Messrs. Breeden, Carter and Moran. All of the members of the Compensation Committee are non-employee directors and are not former officers. During 1999, none of our executive officers served as a member of the Board of Directors or on the compensation committee of a corporation where any of its executive officers served on our Compensation Committee or on our Board of Directors.

Report of the Compensation Committee and our 1999 Board of Directors on Executive Compensation

The Compensation Committee reviews and recommends to our Board of Directors for its approval the salaries and bonuses of our executive officers, including our five executive officers - Howard W. Lutnick, Chairman of the Board and Chief Executive Officer; Frederick T. Varacchi, President and Chief Operating Officer; Douglas B. Gardner, Vice Chairman; Kevin C. Piccoli, Senior Vice President and Chief Financial Officer; and Stephen M. Merkel, Senior Vice President, General Counsel and Secretary. In addition, the Compensation Committee grants stock options under our stock option plan and administers our stock option and stock purchase plans. However, since the Compensation Committee was established by our Board of Directors in connection with our initial public offering in December 1999, compensation for 1999 and stock option issuances in 1999 were determined by our Board of Directors prior to our initial public offering (the "1999 Board of Directors"). Our 1999 Board of Directors consisted solely of Howard W. Lutnick.

Compensation Philosophy

Our executive compensation program is designed to integrate compensation with the achievement of our short and long-term business objectives and to assist us in attracting, motivating and retaining the highest quality executives.

Executive compensation is comprised of three components: (i) a base salary, which is designed to attract talented employees and contribute to motivating and rewarding individual performance; (ii) an incentive bonus of cash, stock and/or options, which is intended to tie financial reward with the achievement of our short-term performance objectives; and (iii) a long-term incentive program, which is designed to promote the achievement of long-term performance goals and to align the long-term interests of our executive officers with those of our stockholders.

The Compensation Committee generally intends that compensation paid to our Chief Executive Officer and the other Named Executive Officers not be subject to the limitation on tax deductibility under Section 162(m) of the Internal Revenue Code, as amended (the "Code"), so long as this can be achieved in a manner consistent with the Committee's other objectives. Section 162(m) generally eliminates a corporation's tax deduction in a given year for payments to certain named executive officers in excess of $1 million, unless the payments result from "qualified performance-based compensation." The Compensation Committee has been advised that compensation paid in 1999 should not be subject to the limitation on deductibility under Code Section 162(m).

Base Salary Compensation

The Compensation Committee believes that the retention of executives who have developed the skills and expertise required to lead our organization is vital to our competitive strength. The Compensation Committee further believes that attracting other key employees who can supplement the efforts of our existing executives is absolutely critical. To this end, it is the Compensation Committee's policy to establish base pay at competitive levels.

Incentive Bonus Compensation

The Compensation Committee believes that compensation should vary with corporate performance and that a significant portion of compensation should continue to be linked to the achievement of business goals. There were no bonuses paid to any executive officer in 1999.

Grants of Stock Options

It is the policy of the Compensation Committee to award stock options to our executive officers and other key employees in order to align their interests with those of our long-term investors and to help attract and retain these persons. The options, therefore, provide value to the recipients only if and when the market price of the Class A Common Stock increases above the option grant price. To that end, there is ongoing review by the Compensation Committee of the market price of the Class A Common Stock and the grant price of options. It is the Compensation Committee's goal to preserve this incentive as an effective tool in motivating and retaining executives.

11

Options to purchase approximately 3,840,000 shares of the Class A Common Stock were granted by the 1999 Board of Directors to our executive officers. The Compensation Committee believes that the grant of these options, including, in particular, with respect to our executive officers, not only provides a meaningful long-term incentive to those individuals who have been identified as key to our future success, but helps retain the services of these persons and further links compensation to our overall performance.

Compensation of Our Chief Executive Officer

Compensation paid during 1999 to Mr. Lutnick was $280,000. No bonus was paid to Mr. Lutnick in 1999. Mr. Lutnick was granted options to purchase 2,500,000 shares of the Class A Common Stock in 1999, 500,000 of which were immediately exercisable and fully vested and 2,000,000 of which vest and become exercisable in five annual installments beginning December 10, 2000. In the future, the Compensation Committee will consider several factors in establishing our Chief Executive Officer's compensation package, including market pay practices, performance level, contributions toward achievement of strategic goals and our overall financial and operating success.

PROPOSAL 2 - APPROVAL OF THE ADDITIONAL INVESTMENT RIGHT

General

On April 26, 2000, we entered into a Subscription Agreement (a "Subscription Agreement") with each of The Williams Companies, Inc. ("Williams") and Dynegy, Inc. ("Dynegy") for the purchase by each of a Unit (collectively, the "Unit") consisting of (i) 789,071 shares (the "Shares") of the Class A Common Stock, par value $0.01 per share, and (ii) warrants (the "Warrants") exercisable for the purchase of up to 666,666 shares of the Class A Common Stock, for an aggregate purchase price for the Unit of $25.0 million. The Warrants have a per share exercise price of $35.203125, a ten year term and are exercisable during the last 4 1/2 years of the term, subject to acceleration under certain prescribed circumstances intended to provide incentives to Williams and Dynegy to invest in four Qualified Verticals as described below. After executing its Subscription Agreement, Williams assigned the agreement and all corresponding rights and obligations to its affiliate, Williams Energy Marketing & Trading Company ("WEM&T").

On June 5, 2000, after receipt of all approvals required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, we consummated the purchase and sale of the Units to each of WEM&T and Dynegy (the "Closing"). As an inducement to WEM&T and Dynegy to invest in us, we granted each of them registration rights with respect to the Shares and the Warrants pursuant to a Registration Rights Agreement, dated June 5, 2000, by and among WEM&T, Dynegy and us. The Shares are not transferable prior to the first anniversary of the Closing.

Each of WEM&T and Dynegy agreed in its Subscription Agreement that, subject to the satisfaction of certain conditions, it will invest $2.5 million in at least four entities (the "Qualified Verticals") to be formed by us and Cantor within 12 months of the Closing (subject to extension for a period not to exceed six months under certain prescribed circumstances). We expect that each Qualified Vertical will be jointly owned by industry market participants, us and Cantor, and will establish a new vertical electronic and telephonic marketplace with us in which such Qualified Vertical will broker and possibly clear transactions for the industry market participants and other clients. We anticipate that the first Qualified Vertical to be so formed will be an electronic and telephonic marketplace for North American wholesale transactions in natural gas, electricity, coal, sulfur dioxide and nitrogen dioxide emissions allowances and weather financial products. Products that may be traded on other Qualified Verticals include natural gas liquids, petrochemicals, crude oil and bandwidth. Each of WEM&T and Dynegy will not necessarily invest in the same Qualified Verticals as the other. Each Subscription Agreement further provides that, in connection with up to four additional Qualified Verticals (the "Additional Investment Right"), WEM&T and, subject to certain limitations, Dynegy will be entitled to invest $25.0 million in shares of the Class A Common Stock at a 10% discount to the average trading price for the 10 trading days preceding the date of such party's investment in such new Qualified Vertical, or, under certain circumstances, the public announcement of the formation of such Qualified Vertical. Any shares of the Class A Common Stock purchased pursuant to the Additional Investment Right will be subject to a 12-month lock-up on transferability. Each Subscription Agreement noted that the Additional Investment Right is subject to stockholder approval, and we agreed to recommend the Additional Investment Right for approval at our next annual meeting of stockholders. Pursuant to the Subscription Agreement, Cantor agreed to vote the shares of our Common Equity beneficially owned by it in favor of the Additional Investment Right.

Each Subscription Agreement also provides that, at such time as when WEM&T and Dynegy (or their permitted affiliate assignees) have made an aggregate equity investment in us of an amount equal to at least $100.0 million, valued on a cost basis (and for so long as such parties maintain ownership of equity securities having such cost basis), Cantor will use its best efforts to cause one designee jointly selected by WEM&T and Dynegy to be nominated to our Board of Directors and to vote its shares of our Common Equity in favor of such designee.

Contemporaneously with the execution of the Subscription Agreements, we entered into a stock purchase agreement (the "Stock Purchase Agreement") with Cantor, as amended, providing for the purchase by us from Cantor (i) at the Closing, of 789,071 shares of the Class A Common Stock, representing half of the number of shares of the Class A Common Stock sold by us to WEM&T and Dynegy pursuant to the Subscription Agreements, for a purchase price of $25.0 million and (ii) of half of the number of shares to be purchased by WEM&T and Dynegy, in the aggregate, each time an Additional Investment Right is exercised for the same purchase price per share as is paid by WEM&T and Dynegy at the time.

Immediately following the Closing, Cantor beneficially owned approximately 77% of our outstanding voting securities, and WEM&T and Dynegy each beneficially owned approximately 1.7% of the outstanding voting securities and each beneficially owned approximately 4.9% of the outstanding Class A Common Stock (in each case after giving effect to the conversion by Cantor prior to the Closing of certain shares of the Class B Common Stock into the Class A Common Stock as contemplated by the Stock Purchase Agreement).

The sale of the Shares and Warrants was exempt from registration under the Securities Act of 1933 in reliance on Section 4(2) of such Act, as a transaction by an issuer not involving a public offering.

15

It is expected that the net proceeds received from us from the sale of the Units, and any net proceeds to be received from us from the exercise of any Additional Investment Right (if approved by the stockholders), will be used for general working capital purposes.

We have currently reserved 5,681,314 shares of the Class A Common Stock (a portion of which may be issued from treasury stock in connection with our purchase of the Class A Common Stock from Cantor pursuant to the Stock Purchase Agreement), for issuance upon exercise of the Additional Investment Rights granted to WEM&T and Dynegy (such number based upon the closing sales price of the Class A Common Stock on The Nasdaq Stock Market on April 25, 2000), which number shall be adjusted from time to time so that an adequate number of shares are reserved at all times.

The rules of The Nasdaq National Market, the exchange on which the Class A Common Stock is listed, require stockholder approval of the Additional Investment Right because of the potential issuance by us, in a private offering, of the Class A Common Stock representing 20% or more of the Class A Common Stock or voting power outstanding before the issuance at a price less than the current market value of the stock.

Reason for the Additional Investment Right and Recommendation of our Board of Directors

The issuance and sale of the Unit and the grant of the Additional Investment Right were a result of arm's-length negotiations between us and each of Williams and Dynegy, and were effected in connection with the leveraging of our experience with financial markets to opportunities in non-financial, business-to-business markets. Dynegy and Williams are leaders in the energy marketplace, and we are therefore seeking to collaborate with them to create the state-of-the-art exchanges necessary to compete successfully in business-to-business energy verticals. The issuance and sale of the Unit and the grant of the Additional Investment Right are intended to assist in aligning the interest of Williams and Dynegy with those of our other stockholders and to provide an incentive to them to ensure the profitable operation of these verticals, thus facilitating our continued growth and financial success.

For these reasons, our Board of Directors approved the transactions involving Dynegy and Williams described above, (and determined that the transactions were fair to, and in the best interests of, us and our stockholders, other than Cantor) and is recommending that the stockholders approve the Additional Investment Right. Our Board of Directors had also considered the opinion of UBS Warburg LLC, formerly Warburg Dillon Read LLC, dated April 26, 2000, to the effect that, as of such date, the transaction, as described in the Subscription Agreements and the exhibits thereto and the Stock Purchase Agreement, was fair, from a financial point of view, to our stockholders other than Cantor.

Due to timing constraints, stockholder approval of the Additional Investment Right was not solicited prior to the Closing. All other aspects of the transactions involving Dynegy and Williams will not be affected by the outcome of the stockholders' vote on the approval of the Additional Investment Right.

Vote Required

Approval of the Additional Investment Right requires the affirmative vote of the majority of the Total Voting Power present in person or by Proxy and entitled to vote on the matter at the Annual Meeting. Pursuant to the Subscription Agreements, Cantor has agreed to vote all of its shares of the Class A Common Stock and the Class B Common Stock beneficially owned by it, representing 95.6% of the Total Voting Power, in favor of the approval of the Additional Investment Right. Accordingly, the affirmative vote of Cantor will be sufficient to approve the Additional Investment Right regardless of the vote of our other stockholders on this proposal.

Recommendation of our Board of Directors

OUR BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE APPROVAL OF THE ADDITIONAL INVESTMENT RIGHT.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

The Formation Transactions

Concurrently with our initial public offering, Cantor contributed to us substantially all of our assets. These assets primarily consist of the proprietary software, network distribution systems, technologies and related contractual rights that comprise our eSpeed(SM) system. In exchange for these assets, we issued to Cantor 43,999,900 shares of the Class B Common Stock, representing approximately 98% of the voting power of our capital stock outstanding at the time. Cantor converted 3,350,000 of these shares into the shares of the Class A Common Stock which it sold in our initial public offering in December 1999.

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

In December 1999, we entered into Assignment and Assumption Agreements with Cantor pursuant to which Cantor contributed 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 issued to Cantor shares of the Class B Common Stock representing approximately 100% of the outstanding shares of our capital stock prior to our initial public offering and we assumed certain liabilities relating to the assets which Cantor contributed 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. 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 provides for a perpetual term. Under the agreement, we own and operate the electronic trading systems and are responsible for providing electronic brokerage services, and Cantor will provide voice-assisted brokerage services, clearance, settlement and other 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 are 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 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

18

pricing decision with respect to transactions that are fully electronic. We may not make a final transaction pricing decision that results in 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 receive the aggregate transaction revenues and pay a service fee to Cantor. In other cases, Cantor receives the aggregate transaction revenues and pays 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 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);

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. Generally, 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 receives the aggregate transaction revenues and pays 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) other than in certain instances in which we receive the aggregate transaction revenues and Cantor receiving a 35% service fee;

o we 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);

o we 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); and

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 receives the aggregate transaction revenues and pays 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 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 receive 100% of the transaction revenues and do 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 receive 2.5% of the transaction revenues.

In addition, if the electronic marketplace is collaborative with Cantor and the transactions relate to a gaming business, we receive a service fee equal to 25% of the net trading revenue.

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,

19

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.

System Services

We also 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 other 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 do 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 application in a gaming business. Cantor pays to us an amount equal to the direct and indirect costs, including overhead, that we incur in performing these services. We do not receive service fees or are otherwise 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 and (4) 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 our 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 servicemarks "Cantor Exchange(SM)," "Interactive Matching(SM)" and "CX(SM)".

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:

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 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.

20

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 other 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 other 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 other 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 other 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; or

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.

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 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 acquirer 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

21

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 provides certain administrative and management services to us. Cantor makes 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 arrange for our insurance coverage and 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 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. Under the Administrative Services Agreement, we provide sales, marketing and public relations services to Cantor. Cantor reimburses 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 entered into by Cantor and us, Cantor has received piggyback and demand registration rights.

The piggyback registration rights allow Cantor to register the shares of the 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 the 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 the Class A Common Stock to be used as consideration for acquisitions of additional businesses; and

o registrations relating to employee benefit plans.

Cantor also has the right, on three occasions, to require that we register under the Securities Act any or all of the shares of the 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 our initial public 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 Agreement.

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; 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 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. Cantor owns shares of the Class A Common Stock and the Class B Common Stock representing approximately 95.6% of the

22

Total Voting Power. 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.

Consulting Services

For consulting services provided to us and Cantor by Martin J. Wygod in connection with our initial public offering, we have issued to Martin J. Wygod or his designees warrants to purchase 135,000 shares of the Class A Common Stock. The warrants have a five-year term and are exercisable commencing on the first anniversary of the date of issuance at a price per share equal to the initial public offering price. The warrants are not transferable, other than to charities and trusts established for the benefit of Mr. Wygod's children and grandchildren.

We granted Mr. Wygod piggyback and demand registration rights in connection with the warrants. The piggyback registration rights allow Mr. Wygod to have registered the shares of the 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 also has the right, on one occasion, to require that we register under the Securities Act of 1933, a minimum of 75% of the aggregate number of shares of the 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.

Williams and Dynegy Transaction

Please see Proposal 2 - Approval of the Additional Investment Right for a description of a transaction involving Williams, Dynegy, Cantor and us.

Municipal Partners

On July 21, 2000, Cantor acquired the brokerage business of Municipal Partners, Inc. ("MPI") pursuant to an Asset Purchase Agreement by and among us, Cantor, MPI and the individuals signatory thereto for a cash payment of $1,500,000. In connection therewith, we issued to MPI's stockholders 28,374 shares of the Class A Common Stock (the "Restricted Stock") having a value at the date of issuance of $1,250,000 based on the average of the daily volume-weighted closing sales price of the Class A Common Stock as reported on the Nasdaq National Market for the 10 days preceding July 21, 2000. The Restricted Stock is subject to a lock-up, which will be released as to 1/3 of the shares on each of April 1, 2001, July 21, 2001 and July 21, 2002. Although the purchased assets are owned by Cantor, we are entitled to 100% of the revenues generated from any fully electronic transaction effected in a marketplace utilizing the eSpeed(SM) system pursuant to the Joint Services Agreement. In addition, in order to provide incentives to promote the use of the eSpeed trading platform in connection with the purchased business, we granted an aggregate of 28,374 restricted shares of the Class A Common Stock (the "Additional Stock"), pursuant to our long-term incentive plan for an aggregate of $1,250,000 to certain employees and shareholders of MPI that joined Cantor
(the "Holders") in exchange for interest-bearing promissory notes (the "Notes")
in the same aggregate principal amount. The Additional Stock may be redeemed, at our option, by cancellation of the related Note if we do not receive $3,000,000 in electronic transaction revenues generated by Cantor's municipal bond brokerage business for any consecutive twelve-month period during the three years following the closing on July 21, 2000. The Holders were granted piggyback registration rights with respect to the Additional Stock.

Insider Compensation

Joseph Shea, one of our directors, will receive a total of $250,000 from us in fiscal year 2000 as compensation for his services as one of our employees.

Indemnification by Cantor

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

23

Reverse Repurchase Agreements

We purchase overnight U.S. Treasury securities under agreements to resell with Cantor. At June 30, 2000, the overnight securities totaled $147,141,828, including accrued interest. The securities collateralizing the resell agreements are held under a custodial arrangement with a third party bank.

INDEPENDENT AUDITORS

Upon the recommendation of the Audit Committee, our Board of Directors selected Deloitte & Touche LLP as our independent auditors for the fiscal year ending December 31, 2000. One or more representatives of Deloitte & Touche LLP are expected to attend our Annual Meeting to respond to appropriate questions. They will have an opportunity to make a statement if they so desire. Material non-audit services will be approved by the Audit Committee prior to the rendering of such services after due consideration of the effect of the performance thereof on the independence of the auditors.

EXPENSES OF SOLICITATION

The total cost of the Proxy solicitation will be borne by us. In addition to the mails, Proxies may be solicited by our directors and officers by personal interviews, telephone and telegraph. We have retained D.F. King & Co., Inc., New York, New York, to assist in the solicitation of Proxies for a fee estimated to be $5,000 plus reimbursement of out-of-pocket expenses. It is anticipated that banks, brokerage houses and other custodians, nominees and fiduciaries will forward soliciting material to the beneficial owners of shares of Common Equity entitled to vote at our Annual Meeting and that such persons will be reimbursed for their out-of-pocket expenses incurred in this connection.

STOCKHOLDER PROPOSALS

We intend to hold our 2001 Annual Meeting of Stockholders in or around June 2001. Stockholders are hereby notified that, if they intend to submit proposals for inclusion in our Proxy Statement and Proxy for our 2001 Annual Meeting of Stockholders, such proposals must be received by us no later than February 28, 2001 and must otherwise be in compliance with applicable Securities and Exchange Commission regulations.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act, requires our officers, directors and persons who beneficially own more than 10% of the Class A Common Stock to file reports of ownership of such securities with the Securities and Exchange Commission. Such officers, directors and 10% stockholders are also required by Securities and Exchange Commission regulations to furnish us with copies of all
Section 16(a) forms they file.

Based solely on a review of the copies of the forms furnished to us, we believe that for the fiscal year ended December 31, 1999 our officers, directors and 10% stockholders filed all required Section 16(a) forms on a timely basis, except for (1) an untimely filing by Mr. Merkel of a Form 4 to reflect shares of the Class A Common Stock purchased by his spouse at the time of our initial public offering and (2) an untimely filing by Mr. Moran of an amendment to his Form 3 to reflect shares purchased by him at the time of our initial public offering.

MISCELLANEOUS

Our Board of Directors knows of no other business to be presented at our Annual Meeting. If, however, other matters properly do come before our Annual Meeting, it is intended that the Proxies in the accompanying form will be voted thereon in accordance with the judgment of the person or persons holding such Proxies.

24

STOCKHOLDERS ARE URGED TO COMPLETE, DATE, SIGN AND MAIL PROMPTLY THE ENCLOSED PROXY IN THE ENVELOPE PROVIDED. PROMPT RESPONSE WILL GREATLY FACILITATE ARRANGEMENTS FOR THE ANNUAL MEETING, AND YOUR COOPERATION WILL BE APPRECIATED.

eSpeed, Inc.
Audit Committee Charter

Purpose and Role

The Audit Committee is a committee of the Board of Directors consisting of solely independent directors, as defined in NASD Rule 4200(a)(14).

7. Review and concur with the appointment, replacement, re-assignment or dismissal of the senior internal auditing executive.

26

8. Review the annual audited financial statements with management, including major issues regarding accounting and auditing principles and practices as well as the adequacy of internal controls that could significantly affect the Company's financial statements.

9. Periodically consult with management and the independent auditor about significant financial risk exposures within the business, and assess the steps taken to monitor and control such exposures to the Company.

10. Consider and review with management and the independent auditor, the adequacy of the Company's internal controls (including computerized information system controls and security) and the integrity of the Company's financial reporting processes, both internal and external.

11. Review the regular internal reports to management prepared by the internal auditing department and management's response. Consider the extent to which any changes or improvements identified in the accounting practices and/or internal controls have been implemented.

12. Review any management letters and/or other reports issued by the independent auditor and consider management's response. Consider the extent to which any changes or improvements identified in the accounting practices and/or internal controls have been implemented.

15. Following completion of the annual audit, review separately with management and the independent auditor:

15.1. the Company's annual financial statements and related footnotes;

15.2. the audit report and opinion issued by the independent auditor;

15.3. any significant difficulties encountered during the course of the audit, including any restrictions in the scope of work or access to required information;

15.4. any significant changes or modifications required in the independent auditor's audit plan;

Review an analysis prepared by management and the independent auditor of significant financial reporting issues and judgments made in connection with the preparation of the Company's financial statements. Consider the quality and appropriateness of the Company's accounting principles as applied in its financial reporting.

26. Prepare a letter for inclusion within the annual report that describes the Committee's composition and responsibilities and how they were discharged.

27. The Committee will perform such other functions as assigned by law, the Company's charter or bylaws, or the Board of Directors.

While the Audit Committee has the responsibilities and powers set forth in this Charter, it is not the duty of the Audit Committee to plan or conduct audits or to determine that the Company's financial statements are complete and accurate and are prepared in accordance with generally accepted accounting principles. This is the responsibility of management and the independent auditor.

Nor is it the duty of the Audit Committee to resolve disagreements, if any, between management and the independent auditor, or to assure compliance with laws and regulations and the Company's code of conduct.
