REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees and Participants of the
eSpeed, Inc. Deferral Plan for Employees of
Cantor Fitzgerald, L.P. and Its Affiliates.
New York, NY

We have audited the accompanying statements of net assets available for benefits of the eSpeed, Inc. Deferral Plan for Employees of Cantor Fitzgerald, L.P. and its Affiliates (the "Plan") as of December 31, 2004 and 2003, and the related statement of changes in net assets available for benefits for the year ended December 31, 2004. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2004 and 2003, and the changes in net assets available for benefits for the year ended December 31, 2004, in conformity with accounting principles generally accepted in the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplements schedule of assets held at year-end, is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This schedule is the responsibility of the Plan's management. Such schedule have been subjected to the auditing procedures applied in our audit of the basic 2004 financial statements and, in our opinion, is fairly stated in all material respects when considered in relation to the basic financial statements taken as a whole.

eSpeed, Inc Deferral Plan for Employees of Cantor Fitzgerald, L.P. and Its Affiliates

Notes to Financial Statements

1.    Description of Plan

The following description of the eSpeed, Inc. Deferral Plan for Employees of Cantor Fitzgerald, L.P. and Its Affiliates (the "Plan"), formerly the Cantor Fitzgerald Deferral Plan, provides general information concerning the Plan. Participants should refer to the Plan document for a more complete description of the Plan's provisions.

General - The Plan is a defined contribution plan, which is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). The Plan is co-sponsored by Cantor Fitzgerald, L.P. (CFLP) and eSpeed, Inc. (eSpeed).

Eligibility - All full-time employees of CFLP and eSpeed, as well as their participating domestic affiliates (collectively referred to as the "Company") are eligible to participate in the Plan upon hire and reaching the age of 21, except for non-resident aliens who receive no earned income from U.S. sources. Eligibility begins the first day of the following month after these requirements are met.

Participant Contributions - The maximum deferral amount under the Plan that could be elected is the lower of 80% of salary or a certain statutory limit ($13,000 in 2004), which may be adjusted in future years for cost of living adjustments pursuant to Internal Revenue Code section 402(g)(4). In addition, there are other limitations set forth in the Internal Revenue Code, which the Plan must satisfy. Deferrals exceeding the limit will be refunded to the participants. There were no deferrals in excess of Internal Revenue Code limitations related to the 2004 Plan year.

Company Contributions - The Plan allows eligible participants to invest in eSpeed's Class A common stock (the eSpeed Stock Fund). In addition to the election by the participants to contribute to the eSpeed Stock Fund, the Company matches contributions to this fund annually with up to $3,000 of the Company's Class A common stock per participant. For 2004, eSpeed contributed 14,896 shares of its Class A common stock valued at $184,271, which are included in Employer contributions receivable at December 31, 2004.

Investment Options - Participants direct the investment of their contributions into the various investment options offered by the Plan.

Vesting - Participants are vested immediately in their contributions plus actual earnings thereon. Vesting in the Company's contribution portion of their accounts is based on years of continuous service. A participant is 100% vested after three years of credited service, one-third being earned each year.

Forfeitures - Participant contributions are non-forfeitable at all times. Matching contributions are forfeitable in the event a participant terminates before the participant's matching contribution account is fully vested. The unvested portions are forfeited and applied to such future matching contributions at the discretion of the Company. At December 31, 2004 and December 31, 2003, forfeited nonvested accounts totaled $6,784 and $2,635, respectively. These accounts will be used to reduce future employer contributions. During the year ended December 31, 2004, no employer contributions were reduced from forfeited nonvested accounts.

Participant Accounts – Individual accounts are maintained for each Plan participant. Each participant's account is credited with the participant's contribution, the Company's matching contribution, and Plan earnings, and charged with withdrawals and an allocation of Plan losses. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account.

Payments of Benefits Upon Termination of Service - Payment of benefits will begin as soon as practicable following normal retirement age (59½) or disability. Participants may elect to defer receipt until a later date but not later than the April 1st following the calendar year in which the participant attains age 70½.

6




Distributions - For reason other than retirement, death or disability, a participant's account balance will be distributed as soon as practicable after termination. If a participant's account balance is more than $5,000, no distribution will be made prior to normal retirement age without the participant's written consent.

Loans to Participants – A participant may generally borrow funds from the Plan in amounts not exceeding the lesser of $50,000 or one-half of the participant's account balance. Interest on outstanding loans is charged at a fixed rate, as determined by the Plan administrator, which may not be less than a commercial bank's prime rate on the first business day of the month in which the loan is made. The principal amount borrowed must be repaid within five years, unless the amounts borrowed are used to purchase a primary residence. Effective April 1, 2000, participants requesting new loans are limited to having only two outstanding loans at any one time. Participant loans were $467,811 and $622,075 at December 31, 2004 and 2003, respectively.

Plan Termination - Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its sponsorship of the Plan and to terminate the Plan at any time subject to the provisions of ERISA. In the event the Plan is terminated, employees will become 100% vested in their participant account.

2.    Summary of Significant Accounting Policies

Basis of Accounting - The Plan's financial statements have been prepared using accounting principles generally accepted in the United States of America.

Benefit Payments to Participants and Beneficiaries - Benefits are recorded when disbursed.

Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of net assets available for benefits and changes therein. Actual results could differ from the estimates and assumptions used. Estimates that are particularly susceptible to change include assumptions used in determining the fair value of investments.

Risks and Uncertainties - The Plan provides for various investment options. Investment securities are exposed to various risks such as interest rate, market and credit risk. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that the risk factors could materially affect participants' account balances and the amount reported in the statement of assets available for Plan benefits and changes therein.

Investment Valuation - The Plan's investments are stated at fair value. Shares of registered investment companies are valued at quoted market prices, which represent the asset value of shares held by the Plan at year-end. Investments that are not publicly traded, such as common collective trusts, are valued by Wells Fargo, the trustee for the Plan, based on the quoted market prices of the underlying investments. Loan receivables are stated at contract value. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on an accrual basis. Dividends are recorded on the ex-dividend date. Dividends and interest received by the Plan are reinvested into the respective funds.

Investment Options - All investment options are participant-directed.

Related Party Transactions and Expenses - Certain officers and employees of CFLP, who are participants in the Plan, perform administrative services related to the operation, recordkeeping, and financial reporting of the Plan. The Company, at its option, pays these and other administrative expenses on behalf of the Plan. The Plan would pay such expenses if the Company discontinued its practice of paying them.

In addition, some of the Plan's assets are invested in the Wells Fargo S&P 500 Stock Fund, Wells Fargo Russell 2000 Index Fund, Wells Fargo Treasury Plus Inst. Money Market Fund, and the Wells Fargo S&P MidCap Stock Fund, which were collectively valued at $19,475,920 (45% of net assets) and $20,940,354 (48% of net assets) as of December 31, 2004 and 2003, respectively.

7




Wells Fargo also manages the eSpeed Stock Fund on behalf of the Plan, which was valued at $979,511 (2% of net assets) and $1,271,241 (3% of net assets) as of December 31, 2004 and 2003, respectively. Wells Fargo Bank, an affiliate of Wells Fargo's Institutional Investments Group, the Plan's trustee, custodian and record keeper, manages these funds, as part of the Wells Fargo Collective Investment Funds.

Although these transactions qualify as party-in-interest transactions, they are specifically exempt in accordance with certain U.S. Department of Labor Prohibited Transaction Class Exemptions.

3.    Income Tax Status of Plan

The Internal Revenue Service has determined and informed CFLP by letter dated November 26, 2002 that the Plan is qualified as to form with applicable sections of the Internal Revenue Code ("IRC") and, as such, the related trust is exempt from federal income taxes. The Plan has been amended since receiving the latest determination letter. However, the Plan Administrator and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC.
