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.

II-2


(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.

Shares of Class B Common Stock that are converted into shares of Class A Common Stock shall be retired and not reissued.

A statement of the powers, preferences and rights, and the qualifications, limitations or restrictions thereof, in respect of each class of stock of the Corporation is as follows:

PREFERRED STOCK

The Preferred Stock may be issued from time to time by the Board of Directors as shares of one or more classes or series. Subject to the provisions of this Amended and Restated Certificate of Incorporation and the limitations prescribed by law, the Board of Directors is expressly authorized by adopting resolutions to issue the shares, fix the number of shares and change the number of shares constituting any series, and to provide for or change the voting powers, designations, preferences and relative, participating, optional or other special rights, qualifications, limitations or restrictions thereof, including dividend rights (and whether dividends are cumulative), dividend rates, terms of redemption (including sinking fund provisions), redemption prices, conversion rights and liquidation preferences of the shares constituting any class or series of the Preferred Stock, without any further action or vote by the stockholders.

COMMON STOCK

1. Reclassification.

Effective immediately upon the filing with the Secretary of State of the State of Delaware of this Amended and Restated Certificate of Incorporation, and without further action on the part of the holders of the common stock outstanding immediately prior to the time of such filing (the "Outstanding Common Stock"), each share of Outstanding Common Stock shall

2

immediately and automatically be converted into one share of Class B Common Stock. Effective immediately upon the filing with the Secretary of State of the State of Delaware of this Amended and Restated Certificate of Incorporation, each certificate representing a share of Outstanding Common Stock thereafter shall be deemed to represent a share of Class B Common Stock.

2. Voting.

(a) At each annual or special meeting of stockholders, and for all other purposes, each holder of record of shares of Class A Common Stock on the relevant record date shall be entitled to one (1) vote for each share of Class A Common Stock and each holder of record of shares of Class B Common Stock on the relevant record date shall be entitled to ten (10) votes for each share of Class B Common Stock. Except as otherwise required by law and this Amended and Restated Certificate of Incorporation and subject to the rights of holders of any series of Preferred Stock of the Corporation that may be issued from time to time, the holders of shares of Class A Common Stock and shares of Class B Common Stock shall vote together as a single class on all matters voted on by the stockholders of the Corporation.

(b) Neither the holders of shares of Class A Common Stock nor the holders of shares of Class B Common Stock shall have cumulative voting rights.

3. Dividends: Stock Splits.

Subject to the rights of the holders of shares of any series of Preferred Stock, and subject to any other provisions of this Amended and Restated Certificate of Incorporation, holders of shares of Class A Common Stock and shares of Class B Common Stock shall be entitled to receive such dividends and other distributions in cash, stock or property of the Corporation as may be declared thereon by the Board of Directors from time to time out of assets or funds of the Corporation legally available therefor. If at any time a dividend or other distribution in cash or other property (other than dividends or other distributions payable in shares of Common Stock or other voting securities or options or warrants to purchase shares of Common Stock or other voting securities or securities convertible into or exchangeable for shares of Common Stock or other voting securities) is paid on the shares of Class A Common Stock or the shares of Class B Common Stock, a like dividend or other distribution in cash or other property shall also be paid on shares of Class A Common Stock or shares of Class B Common Stock, as the case may be, in an equal amount per share. If at any time a dividend or other distribution payable in shares of Common Stock or options or warrants to purchase shares of Common Stock or securities convertible into or exchangeable for shares of Common Stock is paid on shares of Class A Common Stock or shares of Class B Common Stock, a like dividend or other distribution shall also be paid on shares of Class A Common Stock or shares of Class B Common Stock, as the case may be, in an equal amount per share; provided, however, that, for this purpose, if shares of Class A Common Stock or other voting securities, or options or warrants to purchase shares of Class A Common Stock or other voting securities or securities convertible into or exchangeable for shares of Class A Common Stock or other voting securities,

3

are paid on shares of Class A Common Stock, and shares of Class B Common Stock or voting securities identical to the other securities paid on the shares of Class A Common Stock (except that voting securities paid on the Class B Common Stock may have up to ten (10) times the number of votes per share as voting securities paid on the Class A Common Stock) or options or warrants to purchase shares of Class B Common Stock or such other voting securities or securities convertible into or exchangeable for shares of Class B Common Stock or such other voting securities, are paid on shares of Class B Common Stock, in an equal amount per share, such dividend or other distribution shall be deemed to be a like dividend or distribution. In the case of any split, subdivision, combination or reclassification of shares of Class A Common Stock or Class B Common Stock, the shares of Class A Common Stock or Class B Common Stock, as the case may be, shall also be split, subdivided, combined or reclassified so that the number of shares of Class A Common Stock and Class B Common Stock outstanding immediately following such split, subdivision, combination or reclassification shall bear the same relationship to each other as did the number of shares of Class A Common Stock and Class B Common Stock outstanding immediately prior to such split, subdivision, combination or reclassification.

4. Conversion Rights.

(a) Voluntary Conversion of Class B Common Stock. Each share of Class B Common Stock is convertible into one fully paid and non-assessable share of Class A Common Stock at any time at the option of the holder. In order to exercise the conversion privilege, the holder of any shares of Class B Common Stock to be converted shall present and surrender the certificate or certificates representing such shares during usual business hours at the principal executive offices of the Corporation, or if any agent for the registration or transfer of shares of Class B Common Stock is then duly appointed and acting (said agent being hereinafter called the "Transfer Agent"), then at the office of the Transfer Agent, accompanied by written notice that the holder elects to convert the shares of Class B Common Stock represented by such certificate or certificates, to the extent specified in such notice. Such notice shall also state the name or names (with addresses) in which the certificate or certificates for shares of Class A Common Stock which shall be issuable upon such conversion shall be issued. If required by the Corporation, any certificate for shares of Class B Common Stock surrendered for conversion shall be accompanied by instruments of transfer, in form satisfactory to the Corporation and the Transfer Agent, duly executed by the holder of such shares or his or her duly authorized representative. As promptly as practicable after the receipt of such notice and the surrender of the certificate or certificates representing such shares of Class B Common Stock as aforesaid, the Corporation shall issue and deliver at such office to such holder, or on his or her written order, a certificate or certificates for the number of full shares of Class A Common Stock issuable upon the conversion of such shares. Each conversion of shares of Class B Common Stock shall be deemed to have been effected on the date on which such notice shall have been received by the Corporation or the Transfer Agent, as applicable, and the certificate or certificates representing such shares shall have been surrendered (subject to receipt by the Corporation or the Transfer Agent, as applicable, within thirty (30) days thereafter of any required instruments of transfer as

4

aforesaid), and the person or persons in whose name or names any certificate or certificates for shares of Class A Common Stock shall be issuable upon such conversion shall be deemed to have become on said date the holder or holders of record of the shares represented thereby.

(b) Unconverted Shares. If less than all of the shares of Class B Common Stock evidenced by a certificate or certificates surrendered to the Corporation (in accordance with such procedures as the Board of Directors may determine) are converted, the Corporation shall execute and deliver to or upon the written order of the holder of such certificate or certificates a new certificate or certificates evidencing the number of shares of Class B Common Stock which are not converted without charge to the holder.

(c) No Conversion Rights of Class A Common Stock. The Class A Common Stock has no conversion rights.

(d) Reservation of Shares of Class A Common Stock. The Corporation hereby reserves, and shall at all times reserve and keep available, out of its authorized and unissued shares of Class A Common Stock, for the purposes of effecting conversions, such number of duly authorized shares of Class A Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Class B Common Stock. The Corporation covenants that all the shares of Class A Common Stock so issuable shall, when so issued, be duly and validly issued, fully paid and non-assessable.

5. Liquidation, Dissolution, etc.

In the event of any liquidation, dissolution or winding up (either voluntary or involuntary) of the Corporation, the holders of shares of Class A Common Stock and the holders of shares of Class B Common Stock shall be entitled to receive the assets and funds of the Corporation available for distribution, after payments to creditors and to the holders of any Preferred Stock of the Corporation that may at the time be outstanding, in proportion to the number of shares held by them, respectively, without regard to class.

6. Rights Otherwise Identical.

Except as otherwise expressly set forth in this Amended and Restated Certificate of Incorporation, the rights of the holders of Class A Common Stock and the rights of the holders of Class B Common Stock shall be in all respects identical.

ARTICLE FIVE

From and after the date of the closing of the Corporation's initial public offering of Class A Common Stock, any action required or permitted to be taken by the stockholders of the Corporation must be effected at a duly called annual or special meeting of such holders and

5

may not be effected by any consent in writing by such holders unless all of the stockholders entitled to vote thereon consent thereto in writing. Except as otherwise required by law and subject to the rights of the holders of the Preferred Stock, special meetings of stockholders of the Corporation may be called only by the Chairman of the Board of Directors, or, if the Chairman of the Board is unavailable, by the Vice Chairman acting jointly with the President.

ARTICLE SIX

In furtherance and not in limitation of the powers conferred by law, the Board of Directors is expressly authorized to make, alter and repeal the By-Laws of the Corporation pursuant to a resolution approved by a majority of the Board of Directors. The stockholders may make, alter and repeal the By-Laws of the Corporation only with, and in addition to any other vote required by law, the affirmative vote of the holders of a majority of the voting power of all outstanding shares of capital stock of the Corporation present in person or by proxy and entitled to vote thereon.

ARTICLE SEVEN

No director of the Corporation shall be liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the GCL or (iv) for any transaction from which the director derived an improper personal benefit.

ARTICLE EIGHT

The Corporation shall, to the fullest extent permitted by Section 145 of the GCL, as the same may be amended and supplemented, indemnify each director and officer of the Corporation from and against any and all of the expenses, liabilities or other matters referred to in or covered by said section and the indemnification provided for herein shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any By-Law, agreement, vote of stockholders, vote of disinterested directors or otherwise, and shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such persons, and the Corporation may purchase and maintain insurance on behalf of any director or officer to the extent permitted by Section 145 of the GCL.

ARTICLE NINE

Whenever a compromise or arrangement is proposed between the Corporation and its creditors or any class of them and/or between the Corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of the Corporation or of any creditor or stockholder thereof or on

6

the application of any receiver or receivers appointed for the Corporation under the provisions of section 291 of Title 8 of the Delaware Code or on the application of trustees in dissolution or of any receiver or receivers appointed for the Corporation under the provisions of section 279 of Title 8 of the Delaware Code, order a meeting of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, to be summoned in such manner as the said court directs. If a majority in number representing three-fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, agree to any compromise or arrangement and to any reorganization of the Corporation as a consequence of such compromise or arrangement, the said compromise or arrangement and the said reorganization shall, if sanctioned by the court to which the said application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of the Corporation, as the case may be, and also on the Corporation.

ARTICLE TEN

The Corporation reserves the right to amend, alter, change or repeal any provision contained in this Amended and Restated Certificate of Incorporation, in the manner now or hereafter prescribed by law and this Amended and Restated Certificate of Incorporation, and all rights, preferences and privileges conferred upon stockholders herein are granted subject to this reservation. In addition, the number of authorized shares of Class B Common Stock may not be increased or decreased and the rights of the Class B Common Stock (including the rights set forth in this sentence) 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 B Common Stock. However, the number of authorized shares of Class A Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting power of all outstanding shares of capital stock of the Corporation entitled to vote thereon, irrespective of Del. Code Ann. Tit. 8, Section 242(b)(2).

(the "Company"), its Subsidiaries and its Parent, who wish to become stockholders, an opportunity to purchase Common Stock of the Company. The Board of Directors of the Company (the "Board") believes that employee participation in ownership will be to the mutual benefit of the employees and the Company. The Plan is intended to constitute an "employee stock purchase plan" within the meaning of section 423 of the Internal Revenue Code of 1986, as amended (the "Code").

2. Definitions. Terms not otherwise defined herein shall have the meaning set forth below:

(a) "Committee" means the Board or a committee appointed by the Board to administer the Plan.

(c) "Eligible Employee" means an Employee who is eligible to participate pursuant to Section 4(a).

(d) "Employee" means each individual who is an employee of the Company, a Subsidiary, or Parent for purposes of federal tax withholding; provided, however, that the term Employee shall not include any individual (i) who for purposes of section 423(b)(3) of the Code, is deemed to own stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company, a Subsidiary, or Parent, or (ii) who is on an approved leave of absence that has exceeded 90 days and whose right to reemployment is not guaranteed either by statute or by contract.

(e) "Market Value" means the last sales price of a Share or, if unavailable, the average of the closing bid and asked prices per Share at the end of regular trading on such date (or, if there was no trading or quotation in the Shares on such date, on the next preceding date on which there was trading or quotation) as provided by the national securities exchange or interdealer quotation system on which the Shares are listed or quoted.

The Company shall not be required to segregate or set aside any amounts so deducted, and such bookkeeping entry shall not represent an interest in any assets of the Company. All deducted amounts shall remain part of the Company's general assets until they are applied to purchase Shares under the Plan, and until such time may be used by the Company for any corporate purpose.

2

(p) "Subsidiary" shall mean a corporation described in section 424(f) of the Code that has, with the permission of the Board, adopted the Plan.

In administering the Plan, the Committee shall ensure that all Eligible Employees have the same rights and privileges, to the extent required under Section 423(b)(5) of the Code. 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 its Subsidiaries, Participants, and any person claiming any rights under the Plan from or through any Participant, except to the extent the Committee may subsequently modify, or take further action not consistent with, its prior action.

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. Eligibility and Participation.

(a) During each Offering, each Employee shall be eligible to participate in the Plan; provided, however, that with respect to any Offering, the Committee may exclude such Employees who are described in Section 423(b)(4) of the Code.

(b) Each Eligible Employee may elect to participate in an Offering by completing a Purchase Agreement at such time in advance of the commencement of the Offering as determined by the Committee.

(c) Unless otherwise determined by the Committee, the purchase of Shares under the Plan shall be funded solely through payroll deductions accumulated during the Offering Period. In a Purchase Agreement, an Eligible Employee shall designate the percentage (in whole percentages) of

3

Compensation to be deducted from each paycheck, subject to such maximum percentage limit as may be set by the Committee on a uniform basis. Such payroll deductions shall be credited to the Participant's Stock Purchase Account. Increases or decreases to a Participant's rate of payroll deduction during an Offering Period may be permitted based on uniform rules to be established by the Committee.

(d) Any Participant may voluntarily withdraw from the Plan by filing a notice of withdrawal with the Committee at such time in advance as the Committee may specify. Upon such withdrawal, there shall be paid to the Participant the amount, if any, standing to his credit in his Stock Purchase Account.

(e) If a Participant ceases to be employed by the Company, a Subsidiary, or Parent, participation in the Plan shall cease and the entire amount, if any, standing to the Participant's credit in his Stock Purchase Account shall be refunded to him. If a Participant remains employed by the Company, a Subsidiary, or Parent, but ceases to be an Eligible Employee, he may continue to participate in the Plan through the end of the Offering Period in which such cessation occurs, but may participate thereafter only pursuant to
Section 4(a).

5. Purchase of Shares. Subject to Section 6, on any Purchase Date, there shall be purchased on behalf of each Participant that number of Shares which equals the amount then credited to each Participant's Stock Purchase Account divided by the Purchase Price (rounded down to the nearest whole Share). Any amounts not so applied (i.e., that would result in a fractional Share) shall remain in the Participant's Stock Purchase Account.

6. Limitations.

(a) The aggregate number of Shares that may be purchased under the Plan shall not exceed 425,000.

(b) The aggregate number of Shares that may be purchased by any Participant with respect to any one Offering Period shall not exceed 5,000.

(c) No Eligible Employee shall be granted the right to purchase Shares that would exceed the limitation set forth in Section 423(b)(8) of the Code.

In order to satisfy the foregoing limitations, the Committee shall have the right to (i) decrease or suspend a Participant's payroll deductions, (ii) not apply all or any portion of a Participant's Stock Purchase Account toward the purchase of Shares, and (iii) repurchase Shares previously purchased by a Participant at the Purchase Price paid by the Participant. In respect of Section 6(a) above, any such method shall be applied on a uniform basis.

4

7. Restrictions on Shares. Shares purchased by a Participant shall, for all purposes, be deemed to have been issued at the close of business on the relevant Purchase Date. Prior to that time, none of the rights or privileges of a stockholder of the Company shall inure to the Participant with respect to such Shares. All Shares purchased under the Plan shall be delivered by the Company in a manner as determined by the Committee and 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. The Committee shall have the authority to determine the restrictions, if any, to which Shares shall be subject (including lock-ups and other transfer restrictions), and may condition the delivery of the Shares upon the execution by the Participant of any agreement providing for such restrictions and/or require that the Shares be held in a brokerage or custodial account established with a broker or other custodian selected by the Committee in order to enforce such restrictions.

8. Adjustments.

(a) 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 Shares 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 Shares 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 limitations on the number of Shares that may be purchased under Sections 6(a) and (b), (ii) the kind of Shares reserved for purchase under the Plan, and
(iii) the calculation of the Purchase Price.

(b) If the Shares shall cease for any reason to be listed on any nationally recognized stock exchange or quotation system, the Plan and any Offering hereunder shall thereupon terminate, and the balance then standing to the credit of each Participant in his Stock Purchase Account shall be returned to him.

9. General Provisions.

(a) Compliance With Laws and Obligations. The Company shall not be obligated to issue or deliver Shares 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 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.

5

(b) Nonalienation. The right to purchase Shares under the Plan is personal to the Participant, is exercisable only by the Participant during his lifetime except as hereinafter set forth, and may not be assigned or otherwise transferred by the Participant. Notwithstanding the foregoing, there shall be delivered to the executor, administrator or other personal representative of a deceased Participant such Shares and such residual balance as may remain in the Participant's Stock Purchase Account as of the date the Participant's death occurs. However, such representative shall be bound by the terms and conditions of the Plan as if such representative were a Participant.

(c) Taxes. The Company, a Subsidiary, or Parent, shall be entitled to require any Participant to remit, through payroll withholding or otherwise, any tax that it determines it is so obligated to collect with respect to the purchase or subsequent sale of Shares, and the Committee shall institute such mechanisms as shall insure the collection of such taxes. If Shares acquired with respect to an Offering are sold or otherwise disposed of within two years after the Offering Date or within one year after the Purchase Date, the holder of the Shares 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 Committee may impose such procedures as it determines may be necessary to ensure that such notification is made (e.g., by requiring that Shares be held in a brokerage or custodial account established with a broker or other custodian selected by the Committee).

(d) 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.

(e) Changes to the Plan. The Board may amend, alter, suspend, discontinue or terminate 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 Shares 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 with respect to any Shares previously purchased by the Participant. Upon termination of the Plan, any amounts then credited to a Participant's Stock Purchase Account shall be returned to the Participant.

(f) 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

6

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 or purchase rights otherwise than under the Plan, and such arrangements may be either applicable generally or only in specific cases.

(g) Governing Law. The validity, construction and effect of the Plan, any rules and regulations relating to the Plan 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.

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.

(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 relates to

5

Financial Products, the Data shall belong solely to the Cantor Parties, (ii) if the Data relates to a Collaborative Marketplace in which only Products that are 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.

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 CFLP 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 CFLP a service fee equal to 20% of the Transaction Revenues.

(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.

6

(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 eSpeed will receive and retain all of the Transaction Revenues.

(h) If (i) a transaction is effected in a 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 Cantor 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 a transaction 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 a cash transaction 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 transaction 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 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

7

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, including overhead, costs that the eSpeed Parties incur in performing those services.

6. Representations and Warranties.

(a) Organization and Good Standing.

(i) Each Executing Cantor Party is duly organized, validly existing and in good standing under the laws of the state of its incorporation or organization, as the case may be.

8

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.

(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, 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

9

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 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

10

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) 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 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 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 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

11

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 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 ("Alliance Opportunities") with Persons 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 operations 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 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 License.

Subject to the following sentence, CFLP hereby grants 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 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

12

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.

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, 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

13

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 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

14

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 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, earthquake, governmental regulation or direction, acts of the public enemy, war, rebellion, insurrection, riot, invasion, strike or lockout; provided, however, that such party shall resume the performance whenever such causes are removed.

15. Post-Termination Payments. Notwithstanding any provision herein to the contrary, all payment obligations hereof shall survive the happening of any termination of this Agreement until all amounts due hereunder have been paid.

16. Confidentiality.

(a) CFLP and its affiliates agree to treat as confidential and not to disclose to any person (other than to CFLP employees who have a need to know the same for purposes of CFLP's performing its obligations hereunder) or use the same for its own benefit or for any purpose other than performing its obligations hereunder, all confidential or proprietary information, trade secrets,

15

information related to, and all subject matter covered by, any pending patent applications, data, plans, strategies, projections, budgets, reports, research, financial information, files, reports, software, agreements and other materials and information (individually and collectively, "Confidential Information") it receives, obtains or learns about eSpeed and its affiliates, an Electronic Marketplace or any other program, service, software or system eSpeed and/or CFLP develops in connection with this Agreement. CFLP shall notify those of its employees who perform services for eSpeed and its affiliates of this covenant and shall, to the extent practical, secure their agreement to abide by its terms.

(b) eSpeed and its affiliates agree, during the term of this Agreement, to treat as confidential and not to disclose to any person (other than to eSpeed employees who have a need to know the same for purposes of eSpeed's performing its obligations hereunder) or use the same for its own benefit or for any purpose other than performing its obligations hereunder, all Confidential Information it receives, obtains or learns about CFLP and its affiliates or any other program, service, software or system CFLP and/or eSpeed develops in connection with this Agreement. eSpeed shall notify those of its employees who perform services under this Agreement of this covenant and shall, to the extent practical, secure their agreement to abide by its terms.

(c) Notwithstanding the foregoing, neither party shall be obligated with respect to confidential or proprietary information that it can document: (i) is or has become readily publicly available through no fault of its own or that of its affiliates, employees or agents; or (ii) is received from a third party lawfully in possession of such information and lawfully empowered to freely disclose such information to it; or (iii) was lawfully in its possession, without restriction, after the date hereof.

17. Miscellaneous.

(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.

(b) No waiver by any party hereto of any of its rights under this Agreement shall be effective unless in writing and signed by an officer of the party waiving such right. No waiver of any breach of this Agreement shall constitute a waiver of any subsequent breach, whether or not of the same nature. This Agreement may not be modified except by a writing signed by officers of each of the parties hereto; provided, however, that each amendment, modification and/or waiver hereof or hereunder must be approved by a majority of the outside directors of eSpeed or the applicable eSpeed Party. For purposes of this Agreement, an outside director shall mean a director who is not an employee, partner or affiliate (other than solely by reason of being an eSpeed director) of eSpeed, CFLP or any of their respective affiliates.

(c) This Agreement constitutes the entire Agreement of the parties with respect to the services and benefits described herein, and cancels and supersedes any and all prior written or oral contracts or negotiations between the parties with respect to the subject matter hereof.

16

(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.

(f) The descriptive headings of the several sections hereof are inserted for convenience only and shall not control or affect the meaning or construction of any of the provisions hereof.

5. Charges for Insurance. The insurance provided for in Section 2 shall be invoiced to and paid by eSpeed as follows:

The premiums for each of the insurance policies described in Section 2 shall be allocated to eSpeed by Cantor and shall be determined by multiplying Cantor's total actual insurance premiums for each such coverage by a fraction, (i) in the case of general liability or business interruption insurance, the numerator of which is the aggregate consolidated net revenues (determined in accordance with Generally Accepted Accounting Principles of the United States of America) of eSpeed and the denominator of which is the aggregate consolidated net revenues of Cantor plus any consolidated eSpeed

5

net revenues not included in Cantor's consolidated net revenues, excluding the revenues from any division or subsidiary which does not benefit from or which is not covered by the insurance to which these premiums relate, (ii) in the case of property and casualty insurance, the numerator of which is the number of employees of eSpeed and the denominator of which is the number of employees of eSpeed and Cantor's affiliates, and (iii) in the case of all others as mutually agreed to by eSpeed and Cantor.

6. Charges for Services. In consideration for providing the financial, administrative, sales and marketing, and operational services provided for in
Section 3 hereof, each party shall pay to the other the actual costs of such services, determined as follows:

Each party shall charge the other for such party's pro rata share of the aggregate costs actually incurred, including any applicable taxes, in connection with the provision of such services by the providing party based upon an amount equal to the direct cost that the providing party incurs in performing those services, plus a reasonable allocation of other costs determined in a consistent and fair manner so as to cover such providing party's appropriate costs or in such other manner as the parties shall agree. Such charges shall be determined on a monthly basis and shall be payable in accordance with Section 13 hereof. It is the intent of the parties hereto that each party shall reimburse the other for the costs and expenses (including overhead costs) reasonably incurred by the providing party in furnishing the aforesaid services to the requesting party. Each party may request and receive a review of the amount of such charges incurred for services performed for it by the providing party by giving such party written notice of its desire for such review.

7. Other Benefits and Services. From time to time, Cantor and eSpeed may agree to assist each other in the purchase of other benefits or services or in the purchase by eSpeed from or through Cantor of other benefits or services. In such event, the parties shall agree upon a mutually satisfactory basis of allocation of costs.

8. Exculpation and Indemnity; Other Interests.

(a) Cantor (including its partners, officers, directors and employees) shall not be liable to eSpeed or the stockholders of eSpeed for any acts or omissions taken or not taken in good faith on behalf of eSpeed and in a manner reasonably believed by Cantor to be within the scope of the authority granted to it by this Agreement and in the best interests of eSpeed, except for acts or omissions constituting fraud or willful misconduct in the performance of Cantor's duties under this Agreement. Notwithstanding the foregoing, Cantor shall be liable to eSpeed for any losses incurred by eSpeed in connection with the provision of Cantor's services hereunder to the extent Cantor is entitled to be reimbursed by an unaffiliated third party for any such liability. eSpeed shall indemnify, defend and hold harmless Cantor (and its partners, officers, directors and employees) from and against any and all claims or liabilities of any nature whatsoever (including consequential damages and reasonable attorney's fees) arising out of or in

6

connection with any claim against Cantor under or otherwise in respect of this Agreement, except where attributable to the fraud or willful misconduct of Cantor.

(b) eSpeed (including its officers, directors and employees) shall not be liable to Cantor or the partners of Cantor for any acts or omissions taken or not taken in good faith on behalf of Cantor and in a manner reasonably believed by eSpeed to be within the scope of the authority granted to it by this Agreement and in the best interests of Cantor, except for acts or omissions constituting fraud or willful misconduct in the performance of eSpeed's duties under this Agreement. Notwithstanding the foregoing, eSpeed shall be liable to Cantor for any losses incurred by Cantor in connection with the provision of eSpeed's services hereunder to the extent eSpeed is entitled to be reimbursed by an unaffiliated third party for any such liability. Cantor shall indemnify, defend and hold harmless eSpeed (and its stockholders, officers, directors and employees) from and against any and all claims or liabilities of any nature whatsoever (including consequential damages and reasonable attorney's fees) arising out of or in connection with any claim against eSpeed under or otherwise in respect of this Agreement, except where attributable to the fraud or willful misconduct of eSpeed.

(c) Nothing in this agreement shall prevent Cantor and its affiliates from engaging in or possessing an interest in other business ventures of any nature or description, independently or with others, whether currently existing or hereafter created, and none of eSpeed or any of their respective stockholders shall have any rights in or to such independent ventures or to the income or profits derived therefrom.

9. Relationship of the Parties. The relationship of Cantor and eSpeed, eSpeed Securities, eSpeed GS, eSpeed Markets and eSpeed International shall be that of contracting parties, and no partnership, joint venture or other arrangement shall be deemed to be created hereby. Except as expressly provided herein, none of Cantor, eSpeed, eSpeed Securities, eSpeed GS, eSpeed Markets or eSpeed International 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.

10. Audit. Either party may request a review, by those certified public accountants who examine Cantor's or eSpeed's books and records, of the other party's cost allocation to the requesting party to determine whether such allocation is proper under the procedures set forth herein. Such a review is to be conducted at the requesting party's expense.

11. Documentation. Each party's charges to the other for all services and benefits hereunder shall be substantiated by appropriate schedules, invoices or other documentation.

7

12. Actual Cost. Any charges to the recipient for services or benefits provided by Cantor or eSpeed, as the case may be, or by third parties pursuant to Section 2 or 3 hereof shall be based upon rates not intended to provide a profit to Cantor or eSpeed.

13. Invoicing and Billing. Each party shall invoice the other for charges for services provided pursuant hereto on a monthly basis as incurred, such invoices to be delivered to the other within 15 days after the end of each calendar month. Such invoices may include third party charges incurred in providing services pursuant to Section 2 or 3 hereof or, at the invoicing party's option, services provided by one or more third parties may be invoiced directly to the recipient of those services. Each party shall pay to the other the aggregate charge for 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 netted against amounts due by the second party to the first under this or any other agreement.

14. Services by Third Parties. Except with respect to space made available to eSpeed pursuant to Annex A and Annex B, eSpeed (and Cantor, with respect to sales, marketing and public relations services) may, without cause, procure any of the services or benefits specified in Section 2 and/or Section 3 hereof from a third party or may provide such services or benefits for itself. Cantor (or eSpeed) shall discontinue providing such services or benefits upon written notice by the discontinuing party, delivered at least three months before the requested termination date.

15. Excused Performance. Cantor (and eSpeed, with respect to sales and marketing services) does not warrant that any of the services or benefits herein agreed to be provided shall be free of interruption caused by Acts of God, strikes, lockouts, accidents, inability to obtain third-party cooperation or other causes beyond Cantor's (or eSpeed's) control. No such interruption of services or benefits shall be deemed to constitute a breach of any kind whatsoever.

16. Post-Termination of Payments. Notwithstanding any provision herein to the contrary, all payment obligations hereof shall survive the happening of any event causing termination of this Agreement until all amounts due hereunder have been paid.

17. Miscellaneous.

(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 obligations or interests in this Agreement or any monies which may be due pursuant hereto without the prior written consent of the other parties.

(2) general words shall not be given a restrictive meaning by reason of the fact that such words are followed by particular examples intended to be embraced by the general words, and references to writing includes any method of reproducing words in a legible and non-transitory form.

(c) No waiver by any party hereto of any of its rights under this Agreement shall be effective unless in writing and signed by an officer of the party waiving such right.

ANNEX A

Space Sharing

(a) License to Use Space. During the term of this Agreement, Cantor shall permit eSpeed to use a portion of Cantor's (or any of its subsidiaries' or affiliates') offices ("Cantor's Offices") for the purposes permitted under the lease agreements pursuant to which either Cantor or such subsidiary or affiliate leases such offices (to the extent such offices are leased), subject to the terms and conditions set forth in this Agreement for a term coterminous with respect to any respective lease. The space to be used by eSpeed shall be initially as shown below, but may be expanded or contracted if and as mutually agreed by the parties from time to time.

(b) Consideration. So long as eSpeed uses any portion of Cantor's Offices, eSpeed shall pay to Cantor on the first day of each calendar month with respect to each such Cantor's office an amount equal to the product of (X) the average rate per square foot then being paid by Cantor (or any of its affiliates) for the specific Cantor's Office, and (Y) the number of square feet agreed to pursuant to paragraph (a) above, in each case determined in the same manner as rent is computed under the relevant lease, or if the office(s) are owned by Cantor, in an amount and in the same manner as the parties agree is customary for commercial leases of similar offices. Payments for any partial calendar month shall be prorated on a per diem basis.

(c) Compliance with Leases. eSpeed hereby agrees not to take any action or fail to take any action in connection with its use of a portion of Cantor`s Offices a result of which would be Cantor's violation of any of the terms and conditions of any lease or other restriction on Cantor's use of such offices. eSpeed agrees to comply with the terms and provisions of any such leases for Cantor's Offices in which it or they use space.

ANNEX B (London)

Space Sharing for One America Square, London

(a) License to share space. During the term of this Agreement, and for so long only as eSpeed remains a company which is within the same group as Cantor Fitzgerald International ("CFI"), eSpeed may share with CFI the occupation of the whole or any part of CFI's premises at One America Square ("CFI's Offices") for the purposes permitted under the tenancies pursuant to which CFI leases the CFI Offices, subject to the terms set out in this Annex B. The space to be shared by eSpeed and CFI shall be initially as shown below, but may be expanded or contracted if and as mutually agreed by the parties from time to time. At the request of CFI, eSpeed shall vacate the CFI Offices immediately upon ceasing to belong to the same group as CFI. In this Annex B, a company is any body corporate and two companies are within the same group as one another if one company is the holding company of another or if both are subsidiaries of the same holding company ("holding company" and "subsidiary" having the meanings given to them by Section 736 UK Companies Act 1985).

(b) Consideration. So long as eSpeed shares any part of the CFI Offices, eSpeed shall pay to Cantor, on behalf of CFI, on the first day of each calendar month with respect to each such CFI Office an amount equal to the product of (X) the average rate per square foot then being paid by CFI for the specific CFI Office (such amount to include rent and any service charge, insurance charge, rates and other outgoings of CFI) and (Y) the number of square feet agreed pursuant to paragraph (a) above. Payments for any partial calendar month shall be prorated on a daily basis.

(c) Compliance with leases. eSpeed hereby agrees not to take any action or fail to take any action in connection with its sharing of any part of the CFI Offices as a result of which would be CFI's breach of any of the terms and conditions of any lease or other restriction or obligation affecting CFI's use of such offices. eSpeed agrees to comply with the terms and provisions of any such leases of the CFI Offices in which it shares space. There is no intention to create between eSpeed, Cantor and/or CFI the relationship of lessor and lessee in relation to the CFI Offices.

REGISTRATION RIGHTS AGREEMENT (this "Agreement") dated as of _____________ between eSpeed, Inc., a Delaware corporation (the "Company"), and the other parties that have executed the signature pages hereto (the "Initial Investors") or otherwise execute a joinder agreement and become a party hereto (collectively, the "Investors").

RECITALS

WHEREAS, the Company and the Initial Investors have entered into an Assignment and Assumption Agreement, dated as of the date hereof, pursuant to which the Company issued certain securities to each of the Initial Investors;

NOW THEREFORE, in consideration of the mutual covenants and agreements and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

ARTICLE I
DEMAND REGISTRATIONS

1.1 Requests for Registration. Subject to Sections 1.2 and 1.3 hereof, the Required Investors may request, in writing, registration under the Securities Act of all or part of their Registrable Securities. Within twenty
(20) days after receipt of any such request, the Company will give notice of such request to all other Investors. Thereafter, the Company will use all reasonable efforts to effect the registration under the Securities Act (i) on Form S-1 or any similar long-form registration statement (a "Long-Form Registration") or (ii) on Form S-3 or any similar short-form registration statement (a "Short-Form Registration") if the Company qualifies to effect a Short Form Registration, and will include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within twenty (20) days after the receipt of the Company's notice, subject to the provisions of Section 1.4. All registrations requested pursuant to this Section 1.1 are referred to herein as "Demand Registrations". The Company shall not be required to effect any Demand Registration requested by a Required Investor 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 Article II hereof apply or (b) such Required Investor may sell all of the Registrable Securities requested to be included in such Demand Registration without registration under the Securities Act, pursuant to the exemption provided by (i) Rule 144(k) under the Securities Act, as such rule may be amended from time to time, or (ii) any similar rule or regulation hereafter adopted by the Commission.

1.2 Number of Demand Registrations; Expenses. Subject to Sections 1.1 and 1.3 hereof, the Required Investors shall be entitled to an aggregate of three (3) Demand


Registrations, with no more than one (1) of such Demand Registrations being a Long-Form Registration; provided, however, that the Company need not effect any requested Demand Registration unless the expected proceeds of such registration exceed [$1,000,000.] The Company will pay all Registration Expenses in connection with any Demand Registration, including any Registration Statement that is not deemed to be effected pursuant to the provisions of Section 1.3 hereof.

1.3 Effective Registration Statement. A registration requested pursuant to Section 1.1 of this Agreement shall not be deemed to have been effected (i) unless a Registration Statement with respect thereto has been declared effective by the Commission, (ii) if after it has become effective, such registration is interfered with by any stop order, injunction or other order or requirement of the Commission or other governmental agency or court for any reason, and, as a result thereof, the Registrable Securities covered thereby have not been sold or (iii) the Registration Statement does not remain effective for a period of at least 180 days beyond the effective date thereof or, with respect to an underwritten offering of Registrable Securities, until ninety (90) days after the commencement of the distribution by the holders of the Registrable Securities included in such Registration Statement. If a registration requested pursuant to this Article I is deemed not to have been effected as provided in this Section 1.3, then the Company shall continue to be obligated to effect the number of Demand Registrations set forth in Section 1.2 without giving effect to such requested registration.

1.4 Priority on Demand Registrations. If the Company includes in any underwritten Demand Registration any securities which are not Registrable Securities and the managing underwriters advise the Company in writing that in their opinion the number of Registrable Securities and other shares of Common Stock proposed to be included exceeds the number of Registrable Securities and other securities which can be sold in such offering, the Company will first include in such registration, to the exclusion of any other securities, the number of Registrable Securities requested to be included which, in the opinion of such underwriters, can be sold, pro rata among the Investors on the basis of the amount of Registrable Securities requested to be offered thereby.

1.5 Subsequent Registration Rights. From and after the date of this Agreement, in the event the Company shall, without the written consent of a majority of the holders of Registrable Securities, enter into any agreement with holders or a prospective holder of any securities of the Company giving such holder or prospective holder registration rights the terms of which are more favorable in the aggregate than the registration rights granted to the holders of Registrable Securities hereunder, the Company shall notify the holders of Registrable Securities of such more favorable terms and this agreement shall be modified to reflect such terms.

2

ARTICLE II
PIGGYBACK REGISTRATIONS

2.1 Right to Piggyback. Following the closing of the Public Offering, whenever the Company proposes to register any of its equity securities under the Securities Act (other than pursuant to a Demand Registration and other than for use in a Rule 145 transaction or for registrations for employee plans) and the registration form to be used may be used for the registration of Registrable Securities (a "Piggyback Registration"), the Company will give notice to all Investors of its intention to effect such a registration and will include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within fifteen
(15) days after the receipt of the Company's notice, subject to the provisions of Section 2.3 and 2.4 hereof. Such requests for inclusion shall specify the number of Registrable Securities intended to be disposed of and the intended method of distribution thereof.

2.2 Piggyback Expenses. The Registration Expenses of the Investors will be paid by the Company in all Piggyback Registrations.

2.3 Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering, the Company will include in such registration (i) first, the securities the Company proposes to sell, (ii) second, that number of the Registrable Securities proposed to be included in such registration, pro rata among the respective holders thereof based upon the total number of shares which such holders proposed to include in such registration and (iii) that number of other shares of Common Stock proposed to be included in such registration, pro rata among the respective holders thereof based upon the total number of shares which such holders propose to include in such registration.

2.4 Priority on Secondary Registrations. If a Piggyback Registration is not a Demand Registration pursuant to Article I hereof but is an underwritten secondary registration on behalf of holders (other than the Investors) of the Company's securities, and the managing underwriters advise the Company that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering, the Company will include in such registration (i) first, the number of shares of Common Stock requested to be included by holders and (ii) second, the Registrable Securities requested to be included in such registration by the Investors pro rata based upon the number of shares which such Investors requested to be included.

3

ARTICLE III
HOLDBACK AGREEMENTS

Holdback Obligations. Each holder of Registrable Securities agrees not to effect any public sale or distribution of equity securities of the Company, or any securities convertible, exchangeable or exercisable for or into such securities, during the fifteen (15) days prior to, and the 90-day period beginning on, the effective date of any underwritten Demand Registration (except as part of such underwritten registration), unless (i) the managing underwriters of the registered public offering otherwise agree or (ii) the executive officers, directors and 10% stockholders of the Company shall not be similarly restricted.

ARTICLE IV
REGISTRATION PROCEDURES

Whenever holders of Registrable Securities have requested that any Registrable Securities be registered pursuant to this Agreement, the Company will use reasonable efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof as quickly as possible, and pursuant thereto the Company will as expeditiously as reasonably possible:

(a) prepare and file with the Commission a Registration Statement with respect to such Registrable Securities and use all reasonable efforts to cause such Registration Statement to become and remain effective until the completion of the distribution contemplated thereby; provided, that as promptly as practicable before filing a Registration Statement or Prospectus or any amendments or supplements thereto, the Company will (i) furnish to counsel selected by the holders of Registrable Securities copies of all such documents proposed to be filed and (ii) notify each holder of Registrable Securities covered by such Registration Statement of (x) any request by the Commission to amend such Registration Statement or amend or supplement any Prospectus, or (y) any stop order issued or threatened by the Commission, and take all reasonable actions required to prevent the entry of such stop order or to promptly remove it if entered;

(b) (i) prepare and file with the Commission such amendments and supplements to such Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance with the intended plan of distribution set forth in such Registration Statement and (ii) comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such Registration Statement;

(c) furnish to each seller of Registrable Securities, without charge, such number of conformed copies of such Registration Statement, each amendment and supplement thereto, the Prospectus included in such Registration Statement (including each preliminary Prospectus and, in each case including all exhibits) and such other documents as such seller may

4

reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;

(d) use all reasonable efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions in the United States as any seller thereof shall reasonably request, to keep such registration or qualification in effect for so long as such Registration Statement remains in effect and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller; provided, however, that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this clause (d), (ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction;

(e) use all reasonable efforts (if the offering is underwritten) to furnish to each seller of Registrable Securities a signed copy, addressed to such seller (and the underwriters, if any) of an opinion of counsel for the Company or special counsel to the selling stockholders, dated the effective date of such Registration Statement (and, if such Registration Statement includes an underwritten public offering, dated the date of the closing under the underwriting agreement), covering substantially the same matters with respect to such Registration Statement (and the Prospectus included therein) as are customarily covered in opinions of issuer's counsel delivered to the underwriters in underwritten public offerings, and such other legal matters as the seller (or the underwriters, if any) may reasonably request;

(f) notify each seller of Registrable Securities, at a time when a Prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event known to the Company as a result of which the Prospectus included in such Registration Statement, as then in effect, contains an untrue statement of a material fact or omits to state any fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and, at the request of any such seller, the Company will prepare and furnish such seller a reasonable number of copies of a supplement to or an amendment of such Prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such Prospectus shall not include 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 were made, not misleading;

(g) cause all such Registrable Securities to be listed on each securities exchange and quotation system on which similar securities issued by the Company are then listed and, if such securities are not then listed on a national securities exchange or the Nasdaq Stock Market, cause them to be so listed or qualified; provided, that the Company then meets or is reasonably capable of meeting the eligibility requirements for such an exchange or system and such exchange or system is reasonably satisfactory to the managing underwriters, and to enter

5

ARTICLE VII
INDEMNIFICATION

7.1 Company's Indemnification Obligations. The Company agrees to indemnify and hold harmless each of the holders of any Registrable Securities covered by any Registration Statement referred to herein and each other Person, if any, who controls such holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively, the "Holder Indemnitees"), as follows:

(i) against any and all loss, liability, claim, damage or expense arising out of or based upon an untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment or supplement thereto), including all documents incorporated therein by reference, or in any preliminary Prospectus or Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

7

(ii) against any and all loss, liability, claim, damage and expense to the extent of the aggregate amount paid in settlement of any litigation, investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim based upon any such untrue statement or omission or any such alleged untrue statement or omission, if such settlement is effected with the written consent of the Company; and

(iii) against any and all expense incurred by them in connection with investigating, preparing or defending against any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim based upon any such untrue statement or omission or any such alleged untrue statement or omission, to the extent that any such expense is not paid under clause (i) or (ii) above;

provided, that this indemnity does not apply to any loss, liability, claim, damage or expense to the extent arising out of an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information furnished to the Company by or on behalf of any holder expressly for use in the preparation of any Registration Statement (or any amendment or supplement thereto), including all documents incorporated therein by reference, or in any preliminary Prospectus or Prospectus (or any amendment or supplement thereto); and provided further, that the Company will not be liable to any holder or any other Holder Indemnitee under the indemnity agreement in this Section 7.1 with respect to any preliminary Prospectus or the final Prospectus or the final Prospectus as amended or supplemented, as the case may be, to the extent that any such loss, liability, claim, damage or expense of such Holder Indemnitee results from the fact that such holder sold Registrable Securities to a Person to whom there was not sent or given, at or prior to the written confirmation of such sale, a copy of the final Prospectus or of the final Prospectus as then amended or supplemented, whichever is most recent, if the Company has previously and timely furnished copies thereof to such holder.

7.2 Holder's Indemnification Obligations. In connection with any Registration Statement in which a holder of Registrable Securities is participating, each such holder agrees to indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 7.1 of this Agreement) the Company and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act with respect to any statement or alleged statement in or omission or alleged omission from such Registration Statement, any preliminary, final or summary Prospectus contained therein, or any amendment or supplement thereto, if such statement or alleged statement or omission or alleged omission was made about such holder in reliance upon and in conformity with information furnished to the Company by or on behalf of such holder. The obligations of each holder pursuant to this Section 7.2 are to be several and not joint; provided, that, with respect to each claim pursuant to this Section 7.2, each such holder's maximum liability under this Section shall be limited to an amount equal to the net proceeds actually received by such holder (after

8

deducting any underwriting discount and expenses) from the sale of Registrable Securities being sold pursuant to such Registration Statement or Prospectus by such holder.

7.3 Notices; Defense; Settlement. Promptly after receipt by an indemnified party hereunder of written notice of the commencement of any action or proceeding involving a claim referred to in Section 7.1 or Section 7.2 of this Agreement, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action; provided, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under Section 7.1 or Section 7.2 of this Agreement except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, the indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified, to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof, unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, in which case the indemnifying party shall not be liable for the fees and expenses of (i) more than one counsel for all holders of Registrable Securities, selected by the Required Investors or (ii) more than one counsel for the Company in connection with any one action or separate but similar or related actions. An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of such additional counsel or counsels. The indemnifying party will not, without the prior written consent of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not such indemnified party or any Person who controls such indemnified party is a party to such claim, action, suit or proceeding), unless such settlement, compromise or consent includes an unconditional release of such indemnified party from all liability arising out of such claim, action, suit or proceeding. Notwithstanding anything to the contrary set forth herein, and without limiting any of the rights set forth above, in any event any party will have the right to retain, at its own expense, counsel with respect to the defense of a claim.

7.4 Indemnity Provision. The Company and each holder of Registrable Securities requesting registration shall provide for the foregoing indemnity (with appropriate modifications) in any underwriting agreement with respect to any required registration or other qualification of securities under any Federal or state law or regulation of any governmental authority other than the Securities Act.

9

7.5 Contribution Based on Relative Fault. If the indemnification provided for in Sections 7.1 and 7.2 of this Agreement is unavailable or insufficient to hold harmless an indemnified party under such Sections, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in Section 7.1 or Section 7.2 of this Agreement in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand, and the indemnified party on the other, in connection with statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations, including, without limitation, the relative benefits received by each party from the offering of the securities covered by such Registration Statement, the parties' relative knowledge and access to information concerning the matter with respect to which the claim was asserted and the opportunity to correct and prevent any statement or omission. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statements or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 7.5 were to be determined by pro rata or per capita allocation (even if the underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this Section 7.5. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 7.5 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim (which shall be limited as provided in Section 7.3 of this Agreement if the indemnifying party has assumed the defense of any such action in accordance with the provisions thereof) which is the subject of this Section 7.5. Promptly after receipt by an indemnified party under this Section 7.5 of notice of the commencement of any action against such party in respect of which a claim for contribution may be made against an indemnifying party under this Section 7.5, such indemnified party shall notify the indemnifying party in writing of the commencement thereof if the notice specified in Section 7.3 of this Agreement has not been given with respect to such action; provided, that the omission to so notify the indemnifying party shall not relieve the indemnifying party from any liability which it may otherwise have to any indemnified party under this
Section 7.5, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. The Company and each holder of Registrable Securities agrees with each other and the underwriters of the Registrable Securities, if requested by such underwriters, that (i) the underwriters' portion of such contribution shall not exceed the underwriting discount and (ii) that the amount of such contribution shall not exceed an amount equal to the net proceeds actually received by such indemnifying party from the sale of Registrable Securities in the offering to which the losses, liabilities, claims, damages or expenses of the indemnified parties relate. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

10

7.6 Payments. The indemnification required by this Article VII shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred.
