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
<PAGE>
          (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.

         5.03. 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 Article V or
in the event that a suit, action, investigation, claim or proceeding is begun,
made or instituted as a result of which the Indemnifying Party may become
obligated to the Indemnified Party hereunder, the Indemnified Party shall give
prompt written notice to the Indemnifying Party of the occurrence of such event,
specifying the basis for such claim or demand, and the amount or estimated
amount thereof to the extent then determinable (which estimate shall not be
conclusive of the final amount of such claim or demand); provided, however, that
the failure to give such notice shall not constitute a waiver of the right to
indemnification hereunder, except to the extent that the Indemnifying Party is
actually prejudiced in a material respect thereby. The Indemnifying Party agrees
to defend, contest or otherwise protect 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 that such books and records relate to the condition or operation of
the Business 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 the Business 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 Article V. 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.


                                       14
<PAGE>


         5.04. Payments; Non-Exclusivity. Any amounts due an Indemnified Party
under this Article V 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 legal and other out-of-pocket costs and expenses are reimbursed
currently within fifteen (15) business days after demand therefor. The remedies
conferred in this Article V are intended to be without prejudice to any other
rights or remedies available at law or equity to the Indemnified Parties, now or
hereafter.

approvals and consents of any other persons (including, without limitation, all
third party consents under each of the Assigned Contracts), required to permit
the consummation of all of the transactions contemplated hereby shall have been
obtained or made, as the case may be, to the reasonable satisfaction of
Assignee; provided, however, that it shall not be a condition to Assignee's
obligation to close the transactions contemplated hereby if the failure to
obtain any such approvals, consents or filings would not be material to the
Business or the Assets. For purposes of this Section 6.02, it is understood and
agreed that the failure to obtain any of the approvals, consents and filings
listed on Schedule 6.02 shall be deemed to be material to the Business or the
Assets.

shall have completed its initial public offering of its Class A Common Stock
concurrently with the Closing of the transactions contemplated hereby.

         6.05. No Prohibition. No law, statute, rule or regulation or
injunction, order, judgment, ruling, decree or settlement of any court or
administrative agency shall be in effect which prohibits Assignee from
consummating the transactions contemplated hereby or operating any Asset after
the Closing Date.

         (a) By the mutual written consent of Assignee and the Assignors; or

         (b) By either the Assignors or Assignee in writing, without liability
to the terminating party on account of such termination (provided that the

         The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the GCL.

                                  ARTICLE FOUR

         The total number of shares of all classes of stock which the
Corporation shall have authority to issue is Three Hundred Fifty Million
(350,000,000) shares, consisting of (i) Fifty Million (50,000,000) shares of

Shares of Class B Common Stock that are converted into shares of Class A Common

         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

<PAGE>

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

<PAGE>

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

<PAGE>


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

<PAGE>

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

<PAGE>

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).

                          EMPLOYEE STOCK PURCHASE PLAN


         1. Purpose. The purpose of the eSpeed, Inc. Employee Stock Purchase
Plan (the "Plan") is to provide eligible employees of eSpeed, Inc. (the

         3.  Administration.

         (a) The Plan shall be administered by the Committee who shall have the
authority and power to adopt, construe, and enforce rules and regulations not
inconsistent with the provisions of 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. The Committee may
delegate to officers or managers of the Company, its Parent or its Subsidiaries
the authority, subject to such terms as the Committee shall determine, to
perform such functions as the Committee may determine, to the extent permitted
under applicable law.

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

         4.  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

<PAGE>


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

<PAGE>


         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

<PAGE>


         (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

<PAGE>


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.

                  (b) The parties agree that the Electronic Marketplaces that
are managed by the Cantor Parties prior to the date hereof, all of which are
listed by Product on Annex A hereto, shall be Collaborative Marketplaces
governed by this Section 3. The determination as to whether a Marketplace that
is created after the date hereof is to be a Collaborative Marketplace governed
by this Section 3 shall be made in accordance with Section 7 of this Agreement.

                  (c) In the case of each Collaborative Marketplace, any Product
or Pricing Decision shall be made jointly by the Cantor Parties and the eSpeed
Parties. If the parties are unable to agree on



                                        4

<PAGE>



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

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

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

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

                  (g) All information and data, other than Information, created,
developed, used in connection with or relating to the operation of and effecting
of transactions in any Marketplace ("Data") shall constitute the sole property
of the Cantor Parties or the eSpeed Parties, as applicable, on the following
basis: (i) if the Data relates to


                                        5

<PAGE>


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

<PAGE>



                  (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

<PAGE>



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. Each Executing
         Cantor Party has the requisite power and authority to execute, deliver
         and perform this Agreement and to consummate the transactions
         contemplated hereby.

                           (ii) Each Executing eSpeed Party is duly organized,
         validly existing and in good standing under the laws of the state or
         other jurisdiction of its incorporation or organization, as the case
         may be. Each Executing eSpeed Party has the requisite power and
         authority to execute, deliver and perform this Agreement and to
         consummate the transactions contemplated hereby.

                  (b)      Authority; Binding Effect; No Conflicts.

                           (i) Each Executing Cantor Party has taken all
         necessary actions to authorize the execution and delivery of this
         Agreement and to perform all of its obligations under, and to
         consummate the transactions contemplated by, this Agreement. This
         Agreement has been duly and validly executed by each of the Executing
         Cantor Parties. This Agreement constitutes the valid and binding
         obligation of each of the Executing Cantor Parties enforceable against
         each of the Executing Cantor Parties in accordance with its terms,
         subject to the effect of reorganization, bankruptcy, insolvency,
         moratorium, fraudulent conveyance and other similar laws relating to or
         affecting creditors' rights generally and court decisions with respect
         thereto, and subject to the application of equitable principles and the
         discretion of



                                        8

<PAGE>



         the court (regardless of whether the enforceability is considered in a
         proceeding in equity or at law). The execution, delivery and
         performance by each of the Executing Cantor Parties of this Agreement
         shall not, with or without the giving of notice or the lapse of time or
         both, (x) violate any provision of any federal, state, local or foreign
         law, statute, rule or regulation to which any of the Executing Cantor
         Parties is subject, (y) violate any injunction, order, judgment,
         ruling, decree or settlement applicable to any of the Executing Cantor
         Parties or (z) conflict with, or result in a breach or violation of,
         any provision of the certificate of incorporation, by-laws, partnership
         agreement or similar governing document of any of the Executing Cantor
         Parties or any lease, contract, agreement, instrument, undertaking or
         covenant by which any of the Executing Cantor Parties is bound.

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

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

<PAGE>



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

<PAGE>



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

<PAGE>



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

<PAGE>



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

<PAGE>



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

<PAGE>



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.

                  (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.

         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

<PAGE>



         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.

                  (b) The rule known as the eiusdem generis rule shall not apply
         and accordingly:

                                    generality of any preceding words or be
                                    construed as being limited to the same class
                                    as the preceding words where a wider

                           (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. 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
         or amended except (i) by a writing signed by officers of each of the
         parties hereto and (ii) such modification or amendment is approved by a
         majority of the outside directors of the Board of Directors of eSpeed.
         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 a director of eSpeed) of eSpeed, Cantor or
         any of their respective affiliates.

                  (d) 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.

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

                  (f) 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.

         are inserted for convenience only and shall not control or affect the
         meaning or construction of any of the provisions hereof.

                  (h) Any notice, request or other communication required or
         permitted in this Agreement shall be in writing and shall be
         sufficiently given if personally delivered or if sent by registered or

                                     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

                                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


<PAGE>



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.

                                   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.

                                   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

<PAGE>



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

<PAGE>



into such customary agreements as may be required in furtherance thereof,
including, without limitation, listing applications and indemnification
agreements in customary form;

                  (h) provide a transfer agent and registrar for all such
Registrable Securities not later than the effective date of such Registration
Statement;

                  (i) make available for inspection by any seller of Registrable
Securities, any underwriter participating in any disposition pursuant to such
Registration Statement and any attorney, accountant or other agent retained by
any such seller or underwriter, all financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company's
officers, directors, employees and independent accountants to supply all
information reasonably requested by any such seller, underwriter, attorney,
accountant or agent in connection with such Registration Statement to enable
them to conduct a reasonable investigation within the meaning of the Securities
Act;

                  (j) subject to other provisions hereof, use all reasonable
efforts to cause such Registrable Securities covered by such Registration
Statement to be registered with or approved by such other governmental agencies
or authorities or self-regulatory organizations as may be necessary to enable
the sellers thereof to consummate the disposition of such Registrable
Securities; and

                  (k) promptly notify the holders of the Registrable Securities
of the issuance of any stop order by the Commission or the issuance by any state
securities commission or other regulatory authority of any order suspending the
qualification or exemption from qualification of any of the Registrable
Securities under state securities or "blue sky" laws, and use every reasonable
effort to obtain the lifting at the earliest possible time of any stop order
suspending the effectiveness of any Registration Statement or of any order
preventing or suspending the use of any preliminary Prospectus.


                                    ARTICLE V
                              REGISTRATION EXPENSES

                  5.1 Registration Expenses. All registration and filing fees,
fees and expenses of compliance with securities or blue sky laws (including the
fees and expenses of counsel in connection with blue sky qualifications of the
Registrable Securities), printing expenses, listing fees for securities to be
registered on a national securities exchange or the Nasdaq Stock Market and all
independent certified public accountants, underwriters (excluding discounts and
commissions) and other Persons retained by the Company and reasonable fees and
expenses of one counsel to the holders representing more than 50% of the
Registrable Securities registered in connection with the subject registration
(all such expenses being herein called "Registration Expenses"), will be borne
as provided in Sections 1.2 and 2.2 of this Agreement.



                                        6

<PAGE>



                  5.2 Sellers' Expenses. The Company shall have no obligation to
pay any underwriting discounts or commissions attributable to the sale of
Registered Securities, which expenses will be borne by all sellers of securities
included in such registration in proportion to the aggregate selling price of
the securities to be so registered.


                                   ARTICLE VI
                             UNDERWRITTEN OFFERINGS

                  6.1 Underwriting Agreement. If requested by the underwriters
for any underwritten offering of Registrable Securities pursuant to a Demand
Registration, the Company will enter into an underwriting agreement with such
underwriters for such offering, such agreement to contain such representations
and warranties by the Company and such other terms as are generally included in
agreements of this type, including, without limitation, indemnities customarily
included in such agreements. The holders of the Registrable Securities will
cooperate in good faith with the Company in the negotiation of the underwriting
agreement.

                  6.2 Obligations of Participants in Underwritten Offerings. No
Person may participate in any underwritten registration hereunder unless such

                                   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

<PAGE>



                           (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

<PAGE>



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.

                  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.

unless such modification, amendment or waiver is approved in writing by the
Company and the Investors representing a majority of the Registrable Securities
then outstanding. The failure of any party to enforce any of the provisions of
this Agreement will in no way be construed as a waiver of such provisions and
will not affect the right of such party thereafter to enforce each and every
provision of this Agreement in accordance with its terms.

                  9.3 Successors and Assigns. All covenants and agreements in
this Agreement by or on behalf of any of the parties hereto will bind and inure
