Ladies and Gentlemen:

                  eSpeed, Inc., a Delaware corporation (the "Company") and an
indirect subsidiary of Cantor Fitzgerald, L.P., a Delaware limited partnership
(the "Parent"), proposes to issue and sell to the underwriters named in Schedule
A annexed hereto (the "Underwriters") an aggregate of 2,500,000 shares of its
Class A Common Stock, $.01 par value (the "Common Stock"), Cantor Fitzgerald
Securities, a New York partnership (the "Selling Stockholder") and a subsidiary
of the Parent, proposes to sell to the Underwriters 4,500,000 shares of Common
Stock and certain warrantholders of the Company named in Schedule B annexed
hereto (the "Warrantholders") propose to sell an aggregate of 135,000 shares of
Common Stock upon exercise of their warrants (collectively, the "Firm Shares").
In addition, solely for the purpose of covering over-allotments, the Selling
Stockholder proposes to grant to the Underwriters the option to purchase from
the Selling Stockholder up to an additional 1,070,250 shares of Common Stock
(the "Additional Shares" and, collectively with the Firm Shares, the "Shares").
The Company, the Selling Stockholder and the Warrantholders are hereinafter
sometimes referred to collectively as the "Sellers." The Shares are described in
the Prospectus as defined below.

                  The Company has filed, in accordance with the provisions of
the Securities Act of 1933, as amended, and the rules and regulations thereunder
(collectively called the "Act"), with the Securities and Exchange Commission
(the "Commission") a registration statement on Form S-3 (Reg. No. 333-55746)
including a prospectus, relating to the Shares. The Company has furnished to
you, for use by the Underwriters and by dealers, copies of one or more
preliminary prospectuses (each thereof being herein called a "Preliminary
Prospectus") relating to the Shares. Except where the context otherwise
requires, the registration statement, as amended when it becomes effective,
including all documents filed as a part thereof, and including any information
contained in a prospectus subsequently filed with the Commission pursuant to
Rule 424(b) under the Act and deemed to be part of the registration statement at
the time of effectiveness pursuant to Rule 430(A) under the Act and also
including any registration statement filed pursuant to Rule 462(b) under the
Act, is herein called the "Registration Statement," and the prospectus, in the
form filed by the Company with the Commission pursuant to Rule 424(b) under the
Act on or before the second business day after the date hereof (or such earlier
time as may be required under the Act) or, if no such filing is required, the
form of final prospectus included in the Registration Statement at the time it
became effective, is herein called the "Prospectus." Any reference herein to the
Registration Statement, a Preliminary Prospectus or the Prospectus shall be
deemed to refer to and include the documents incorporated by reference therein
pursuant to Form S-3 which were filed under the Exchange Act on or before the
Effective Date of the Registration Statement or the issue date of such
Preliminary Prospectus or the Prospectus, as the case may be; and any reference
herein to the terms "amend," "amendment" or "supplement" with respect to the
Registration Statement, any Preliminary Prospectus or the Prospectus shall be
deemed to refer to and include the filing of any document under the Exchange Act
after the Effective Date of the Registration Statement, or the issue date of any
Preliminary Prospectus or the Prospectus, as the case may be, deemed to be
incorporated therein by reference.




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

                  1. Sale and Purchase. Subject to such adjustments as you may
determine to avoid fractional shares, the Company hereby agrees, subject to all
the terms and conditions set forth herein, to issue and sell to each Underwriter
and, upon the basis of the representations, warranties and agreements of the
Sellers and the Parent herein contained and subject to all the terms and
conditions set forth herein, each Underwriter agrees, severally and not jointly,
to purchase from the Company, at a purchase price of $_____ per Share (the
"purchase price per share"), that number of Firm Shares which bears the same
proportion to the aggregate number of Firm Shares to be issued and sold by the
Company as the number of Firm Shares set forth opposite the name of such
Underwriter in Schedule A annexed hereto (or such number of Firm Shares
increased as set forth in Section 8 hereof) bears to the aggregate number of
Firm Shares.

                  Subject to such adjustments as you may determine to avoid
fractional shares, the Selling Stockholder hereby agrees, subject to all the
terms and conditions set forth herein, to sell to each Underwriter and, upon the
basis of the representations, warranties and agreements of the Sellers and the
Parent herein contained and subject to all the terms and conditions set forth
herein, each Underwriter agrees, severally and not jointly, to purchase from the
Selling Stockholder at the purchase price per share, that number of Firm Shares
which bears the same proportion to the aggregate number of Firm Shares to be
sold by the Selling Stockholder as the number of Firm Shares set forth opposite
the name of such Underwriter in Schedule A annexed hereto (or such number of
Firm Shares increased as set forth in Section 8 hereof) bears to the aggregate
number of Firm Shares.

                                       2


                  Subject to such adjustments as you may determine to avoid
fractional shares, each of the Warrantholders agrees, subject to all the terms
and conditions set forth herein, to sell to each Underwriter and, upon the basis
of the representations, warranties and agreements of the Sellers and the Parent
herein contained and subject to all the terms and conditions set forth herein,
each Underwriter agrees, severally and not jointly, to purchase from each of the
Warrantholders, at the purchase price per share, that number of Firm Shares
which bears the same proportion to the number of Firm Shares set forth opposite
the name of such Warrantholder in Schedule B annexed hereto as the number of
Firm Shares set forth opposite the name of such Underwriter in Schedule A
annexed hereto (or such number of Firm Shares increased as set forth in Section
8 hereof) bears to the aggregate number of Firm Shares.

                  The Company, the Warrantholders and the Selling Stockholder
are advised by you that the Underwriters intend (i) to make a public offering of
their respective portions of the Firm Shares as soon after the effective date of
the Registration Statement as in your judgment is advisable and (ii) initially
to offer the Firm Shares upon the terms set forth in the Prospectus. You may
from time to time increase or decrease the public offering price after the
initial public offering to such extent as you may determine.

                  The Selling Stockholder agrees, subject to all the terms and
conditions set forth herein, to sell to the Underwriters, and upon the basis of
the representations, warranties and agreements of the Sellers and the Parent
herein contained, the Underwriters shall have the right to purchase from the
Selling Stockholder, severally and not jointly, all or a portion of the
Additional Shares as may be necessary to cover over-allotments made in
connection with the offering of the Firm Shares, at the same purchase price per
share to be paid by the Underwriters to the Company, the Warrantholders and the
Selling Stockholder for the Firm Shares. This option may be exercised by you on
behalf of the several Underwriters at any time (but not more than once) on or
before the thirtieth day following the date hereof, by written notice to the
Selling Stockholder. Such notice shall set forth the aggregate number of
Additional Shares as to which the option is being exercised, and the date and
time when the Additional Shares are to be delivered (such date and time being
herein referred to as the additional time of purchase); provided, however, that
the additional time of purchase shall not be earlier than the time of purchase
(as defined below) nor earlier than the second business day(1) after the date on
which the option shall have been exercised nor later than the tenth business day
after the date on which the option shall have been exercised. The aggregate
number of Additional Shares to be sold to each Underwriter shall be the number
which bears the same proportion to the aggregate number of Additional Shares
being purchased as the number of Firm Shares set forth opposite the name of such
Underwriter on Schedule A hereto bears to the aggregate number of Firm Shares
(subject, in each case, to such adjustment as you may determine to eliminate
fractional shares).

         the Shares is required to be delivered under the Act which, in the
         judgment of the Warrantholders or the Selling Stockholder, would
         require the making of any change in the Prospectus then being used so
         that the Prospectus would not include an untrue statement of material
         fact or omit to state a material fact necessary to make the statements
         therein, in the light of the circumstances under which they are made,
         not misleading; and

                  by federal or state securities laws or principles of public
                  policy and subject to the qualification that the
                  enforceability of obligations of the Company hereunder may be

                  their respective properties may be bound or affected and which
                  is filed as an exhibit to the Registration Statement, other
                  than, in the case of clause (b), such Default Events as would
                  not, individually or in the aggregate, reasonably be expected
                  to have a Material Adverse Effect;



                                       20


                           (xiii) to such counsel's knowledge, (a) none of the

                  affected and which is filed as an exhibit to the Registration
                  Statement, except, in the case of clause (b), any such Default
                  Events as would not, individually or in the aggregate,

                  contracts, licenses, agreements, leases or documents of a

                  Prospectus which have not been so filed, summarized or
                  described as required;

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

                           (xvi) the Company is not and, after giving effect to
                  the offering and sale of the Shares, will not be an
                  "investment company" or an entity "controlled" by an
                  "investment company," as such terms are defined in the
                  Investment Company Act;

                           (xvii) such counsel has read the statements in the
                  Prospectus under the caption "Certain Transactions" and in
                  Item 3 of the Company's Annual Report on Form 10-K for the
                  fiscal year ended December 31, 2000, which is incorporated by
                  reference in the Prospectus, and insofar as such statements
                  constitute summaries of legal matters, contracts, agreements,
                  documents or proceedings referred to therein, or refer to
                  statements of law or legal conclusions, such statements are
                  accurate in all material respects and fairly present the
                  information purported to be shown; and



                                       21


                           (xviii) to the knowledge of such counsel, except as
                  described in the Prospectus, no person is entitled to
                  registration rights under the Act with respect to shares of
                  capital stock or other securities of the Company upon the
                  issue and sale of the Shares to the Underwriters hereunder.

                  In addition, such counsel shall state that such counsel has
         participated in conferences with officers and other representatives of
         the Company and the Parent, representatives of the independent public
         accountants of the Company and representatives of the Underwriters at
         which the contents of the Registration Statement and Prospectus were
         discussed and, although such counsel is not passing upon and does not
         assume responsibility for the accuracy, completeness or fairness of the
         statements contained in the Registration Statement or Prospectus
         (except as and to the extent stated in subparagraphs (vi), (viii) and
         (xvii) above), on the basis of the foregoing nothing has come to the
         attention of such counsel that causes them to believe that the
         Registration Statement or any amendment thereto at the time such
         Registration Statement or amendment became effective contained an
         untrue statement of a material fact or omitted to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, or that the Prospectus or any supplement
         thereto at the date of such Prospectus or such supplement, and at all
         times up to and including the time of purchase or additional time of

         material fact or omitted to state a material fact required to be stated
         therein or necessary to make the statements therein, in light of the

         understood that such counsel need express no belief with respect to the
         financial statements and schedules and other financial, statistical and
         accounting data included in the Registration Statement or Prospectus).

                  each of the Parent and the Selling Stockholder enforceable in
                  accordance with its terms, except as enforcement of rights to
                  indemnity and contribution hereunder may be limited by federal
                  or state securities laws or principles of public policy and
                  subject to the qualification that the enforceability of
                  obligations of the Parent and the Selling Stockholder
                  hereunder may be limited by bankruptcy, insolvency,
                  reorganization, moratorium and other laws relating to or
                  affecting creditors' rights generally and by general equitable

                  consummation by the Parent and the Selling Stockholder of the
                  transactions contemplated hereby other than registration of
                  the Shares under the Act and under Rule 2710 and Rule 2720 of
                  NASDR and except for such other approvals, authorizations,
                  consents, orders and filings as have been obtained or made

                  or (b) under any provision of any license, permit, indenture,
                  mortgage, deed of trust, bank loan or credit agreement or
                  other evidence of indebtedness, or any lease, contract or
                  other agreement or instrument to which the Company, the Parent
                  or the Selling Stockholder or any of their respective
                  subsidiaries is a party or by which any of them or their

                  Stockholder or any of their respective subsidiaries, other
                  than, in the case of clause (b), such Default Events as would
                  not, individually or in the aggregate, reasonably be expected
                  to have a Material Adverse Effect;

                           (iv) to such counsel's knowledge, (a) none of the
                  Company, the Parent or the Selling Stockholder or any of their
                  respective subsidiaries is in violation of its charter or
                  by-laws or partnership agreements, as the case may be, and (b)
                  no Default Event exists under any license, permit, indenture,
                  mortgage, deed of trust, bank loan or credit agreement or

                  Effect;



                                       23


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

                           (vi) such counsel has read the statements in the
                  Prospectus under the captions "Risk factors-- Risks related to
                  our business -- If Cantor or we are unable to protect the
                  intellectual property rights we license from Cantor or own,
                  our ability to operate electronic trading marketplaces may be
                  materially adversely affected", "Risk factors-- Risks related
                  to our business-- If it becomes necessary to protect or defend
                  our intellectual property rights, we may have to resort to
                  costly litigation", "Risk factors-- Risks related to our
                  business-- If our software licenses from third parties are
                  terminated, our ability to operate our business may be
                  materially adversely affected", "Risk factors-- Risks related
                  to our business-- If the strength of our domain names is
                  diluted, the value of our proprietary rights may decrease",
                  "Risk factors-- Risks related to our business-- If we infringe
                  on patent rights or copyrights of others, we could become
                  involved in costly litigation", "Business-- Our intellectual
                  property" and "Certain transactions" and in Item 3 of the
                  Company's Annual Report on Form 10-K for the fiscal year ended
                  December 31, 2000, which is incorporated by reference in the
                  Prospectus, and insofar as such statements constitute
                  summaries of legal matters, contracts, agreements, documents
                  or proceedings referred to therein, or refer to statements of
                  law or legal conclusions, such statements are accurate in all
                  material respects and fairly present the information purported
                  to be shown;

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



                                       24


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

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

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

                  Agreement by the Company and the consummation by the Company
                  of the transactions contemplated hereby do not constitute, and
                  will not result in, a Default Event under any provisions of
                  the articles and memorandum of association of eSpeed
                  International Limited.



                                       25


                  (d) You shall have received at the time of purchase and at the
         additional time of purchase, as the case may be, the opinion of

                  Agreement by the Company and the consummation by the Company
                  of the transactions contemplated hereby do not constitute, and
                  will not result in, a Default Event under any provisions of
                  the articles of incorporation of eSpeed (Japan) Limited.

         opinion of ____________, counsel of the Warrantholders, addressed to

                  binding agreement of each Warrantholder enforceable in
                  accordance with its terms, except as enforcement of rights to
                  indemnity and contribution hereunder may be limited by federal
                  or state securities laws or principles of public policy and
                  subject to the qualification that the enforceability of

                  approvals, authorizations, consents, orders and filings as
                  have been obtained or made (except such counsel need express

         therein or necessary to make the statements therein, in the light of
         the circumstances under which they are made, not misleading.



                                       27


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

                  (l) Each of the Company, the Parent, the Warrantholders and
         the Selling Stockholder will, at the time of purchase or additional
         time of purchase, as the case may be, deliver to you a certificate of
         the Company, the Parent, the Warrantholders or the Selling Stockholder,
         as the case may be, signed by two of its executive officers or partners
         to the effect that the representations and warranties of the Company,
         the Parent, the Warrantholders or the Selling Stockholder, as the case
         may be, as set forth in this Agreement are true and correct as of each
         such date, that the Company, the Parent, the Warrantholders or the
         Selling Stockholder, as the case may be, has performed such of its
         obligations under this Agreement as are to be performed at or before
         the time of purchase and at or before the additional time of purchase,
         as the case may be, and the conditions set forth in paragraphs (i) and
         (j) of this Section 6 have been met (in the case of the Warrantholders,
         only with respect to j).

                  (m) You shall have received signed letters from the holders of
         Common Stock and securities convertible into or exchangeable or
         exercisable for Common Stock (including the Parent and the Selling
         Stockholder) in the form and to the effect contemplated by Section
         3(i)(s).

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

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



                                       28


                  The obligations of the several Underwriters hereunder shall be
subject to termination in the absolute discretion of you or any group of
Underwriters (which may include you) which has agreed to purchase in the
aggregate at least 50% of the Firm Shares, (a) if, since the time of execution
of this Agreement or the respective dates as of which information is given in
the Registration Statement and Prospectus, there has been any material adverse
and unfavorable change, financial or otherwise (other than as referred to in the
Registration Statement and Prospectus), in the operations, business, condition
or prospects of the Company and the Subsidiaries taken as a whole, which would,
in your judgment or in the judgment of such group of Underwriters, make it
impracticable to market the Shares, or (b) if, at any time prior to the time of
purchase or, with respect to the purchase of any Additional Shares, the
additional time of purchase, as the case may be, trading in securities on the
New York Stock Exchange, the American Stock Exchange or the Nasdaq National
Market shall have been suspended or limitations or minimum prices shall have
been established on the New York Stock Exchange, the American Stock Exchange or
the Nasdaq National Market, or if a banking moratorium shall have been declared
either by the United States or New York State authorities, or if the United
States shall have declared war in accordance with its constitutional processes
or there shall have occurred any material outbreak or escalation of hostilities
or other national or international calamity or crisis of such magnitude in its
effect on the financial markets of the United States as, in your judgment or in
the judgment of such group of Underwriters, to make it impracticable to market
the Shares.

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

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

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



                                       29


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

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

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

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



                                       30


                  9. Indemnity and Contribution.

                  (a) The Company, the Parent and the Selling Stockholder
jointly and severally agree to indemnify, defend and hold harmless each
Underwriter, its partners, directors and officers, and any person who controls
any Underwriter within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, and the successors and assigns of all of the foregoing persons
from and against any loss, damage, expense, liability or claim (including the
reasonable cost of investigation) which, jointly or severally, any such
Underwriter or any such person may incur under the Act, the Exchange Act, the
common law or otherwise, insofar as such loss, damage, expense, liability or
claim arises out of or is based upon any untrue statement or alleged untrue
statement of a material fact (i) contained in the Registration Statement (or in
the Registration Statement as amended by any post-effective amendment thereof by
the Company) or arises out of or is based upon any omission or alleged omission
to state a material fact required to be stated in the Registration Statement or
necessary to make the statements made therein not misleading, or (ii) contained
in the Prospectus (the term Prospectus for the purpose of this Section 9 being
deemed to include any Preliminary Prospectus, the Prospectus and the Prospectus
as amended or supplemented by the Company) or arises out of or is based upon any
omission or alleged omission to state a material fact required to be stated in
the Prospectus or necessary to make the statements made therein, in light of the
circumstances under which they were made, not misleading, and in the case of
both clauses (i) and (ii), except insofar as any such loss, damage, expense,
liability or claim arises out of or is based upon any untrue statement or
alleged untrue statement of a material fact contained in and in conformity with
information furnished in writing by or on behalf of any Underwriter (in its
capacity as such) through you (in your capacity as representatives of the
several Underwriters) to the Company expressly for use with reference to such
Underwriter (in its capacity as such) in such Registration Statement or such
Prospectus or arises out of or is based upon any omission or alleged omission to
state a material fact in connection with such information required to be stated
in such Registration Statement or such Prospectus or necessary to make such
information (with respect to the Prospectus, in the light of the circumstances
under which they were made) not misleading, provided, however, that the
indemnity agreement contained in this subsection (a) with respect to any
Preliminary Prospectus or amended Preliminary Prospectus shall not inure to the
benefit of any Underwriter from whom the person asserting any such loss, damage,
expense, liability or claim purchased the Shares which is the subject thereof if
the Prospectus corrected any such alleged untrue statement or omission and if
such Underwriter failed to send or give a copy of the Prospectus to such person
at or prior to the written confirmation of the sale of such Shares to such
person, unless the failure is the result of noncompliance by the Company with
Section 4(i)(g) hereof and provided, further, that the aggregate liability of
the Parent and the Selling Stockholder under this entire Section 9 shall not
exceed an amount equal to 65% of the net proceeds from the sale of the Shares
hereunder.


                                       31


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



                                       32


                  (b) Each Warrantholder, severally and not jointly, agrees to
indemnify, defend and hold harmless each Underwriter, its partners, directors
and officers, and any person who controls any Underwriter within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act, and the successors and
assigns of all the foregoing persons to the same extent as the foregoing
indemnity from the Company, the Parent and the Selling Stockholder to each
Underwriter, but only with reference to written information furnished to the
Company by or on behalf of such Warrantholder specifically for inclusion in the
documents referred to in the foregoing indemnity; provided, that the liability
of each Warrantholder under this subsection (b) shall be limited to an amount
equal to the proceeds to the Warrantholder from the sale of the Warrantholder's
Shares to the Underwriters at the purchase price per share. This indemnity
agreement will be in addition to any liability which a Warrantholder may
otherwise have.

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



                                       33


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

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



                                       34


                  (d) If the indemnification provided for in this Section 9 is
unavailable to an indemnified party under subsections (a), (b) and (c) of this
Section 9 in respect of any losses, damages, expenses, liabilities or claims
referred to therein, then each applicable indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, damages, expenses,
liabilities or claims (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company, the Parent, the Warrantholders and
the Selling Stockholder on the one hand and the Underwriters on the other hand
from the offering of the Shares or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company, the Parent, the Warrantholders and the
Selling Stockholder on the one hand and of the Underwriters on the other in
connection with the statements or omissions which resulted in such losses,
damages, expenses, liabilities or claims, as well as any other relevant
equitable considerations. The relative benefits received by the Company, the
Parent, the Warrantholders and the Selling Stockholder on the one hand and the
Underwriters on the other shall be deemed to be in the same respective
proportions as the total proceeds from the offering (net of underwriting
discounts and commissions but before deducting expenses) received by the
Company, the Warrantholders and the Selling Stockholder and the total
underwriting discounts and commissions received by the Underwriters, bear to the
aggregate public offering price of the Shares. The relative fault of the
Company, the Parent, the Warrantholders and the Selling Stockholder on the one
hand and of the Underwriters on the other shall be determined by reference to,
among other things, whether the untrue statement or alleged untrue statement of
a material fact or omission or alleged omission relates to information supplied
by the Company, the Parent, the Warrantholders or by the Selling Stockholder or
by the Underwriters and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The amount paid or payable by a party as a result of the losses, damages,
expenses, liabilities and claims referred to in this subsection shall be deemed
to include any legal or other fees or expenses reasonably incurred by such party
in connection with investigating, preparing to defend or defending any
Proceeding.



                                       36


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

                  (f) The indemnity and contribution agreements contained in
this Section 9 and the covenants, warranties and representations of the Company,
the Parent, the Warrantholders and the Selling Stockholder contained in this
Agreement shall remain in full force and effect regardless of any investigation
made by or on behalf of any Underwriter, its partners, directors or officers or
any person (including each partner, officer or director of such person) who
