Company Shares being sold, conveyed, transferred, assigned and delivered
hereunder, as soon as reasonably practicable after


                                       6
<PAGE>

the Closing Date, Purchaser will deliver, subject to Section 2.05, to each
Shareholder stock certificates duly registered in the name of such Shareholder
representing that number of shares ("PURCHASER SHARES") of common stock, $0.001
par value per share, of the Purchaser ("PURCHASER COMMON STOCK") equal to the
product of (i) the number of Company Shares owned by such Shareholder
immediately prior to the Closing, multiplied by (ii) a fraction, (x) the
numerator of which shall equal 4,500,000 shares and (y) the denominator of which
shall be the Fully Diluted Share Number (the resultant quotient being referred
to herein as the "Per Share Closing Payment).

A portion of the total number of Purchaser Shares equal to twenty-five percent
(25%) of each Shareholder's Purchaser Shares (the "ESCROW FUND"), as set forth
in Schedule I under the heading "Shares in Escrow", shall be deposited in an
escrow account pursuant to the Escrow Agreement. The Purchaser shall deliver a
certificate or certificates to each Shareholder (and with respect to the Escrow
Shares, the Escrow Agent named in the Escrow Agreement), registered in the name
of such Shareholder, representing the number of Purchaser Shares set forth
opposite the name of such Shareholder in SCHEDULE I hereto under the heading
"Purchaser Shares".

            (c)   As used herein, "FULLY DILUTED SHARE NUMBER" shall mean all of
the issued and outstanding Company Shares at the Closing Date, plus the number
of shares of Company Shares issuable upon exercise, exchange or conversion of
all options, warrants, convertible securities or other rights or obligations of
the Company outstanding at the Closing Date that may, at any time, require the
Company to issue shares of its capital stock.

            SECTION 2.04. COMPANY OPTIONS. Subject to the terms and conditions
set forth herein, each Company Option outstanding on the Closing Date will
automatically, without any further action on the part of the holder of such
Company Option (an "OPTION HOLDER"), be converted into and be deemed to be,
without the need for amendment or modification to any Contract under which such
Company Option has been granted, a Purchaser Option (each such converted
Purchaser Option, a "Converted Option"). The number of shares of Purchaser
Common Stock subject to the Purchaser Options will equal the number of Company
Shares subject to such Company Option being converted immediately prior to the
Closing, multiplied by the Per Share Closing Payment, rounded to the nearest
whole share, without any payment for fractional shares, if any, other than as
provided in Section 2.05. The per share exercise price of each such Company
Option will equal the per Common Share exercise price of such Company Option
being converted immediately prior to the Closing, multiplied by the reciprocal
of the Per Share Closing Payment, rounded up to the nearest whole cent. Each
such Purchaser Option will have substantially the same terms and conditions as
the corresponding Company Option being converted. Notwithstanding the current
terms of the Company Options, in the event that the engagement of any Option
Holder with the Company is terminated by the Company without Cause (i) prior to
the date that is the six month anniversary of the Closing Date, all such Option
Holder's Converted Options shall be deemed to have vested immediately prior to
such termination, (ii) after the date that is the six moth anniversary of the
Closing Date but prior to the twelve month anniversary of the Closing Date, the
Converted Options held by such Option Holder that are scheduled to vest on the
next applicable vesting date shall be deemed to have vested immediately prior to
such termination.

            SECTION 2.05. FRACTIONAL SHARES. With respect to any payment by
Purchaser to be made by delivery of Purchaser Shares pursuant to Section 2.03,
no fractional shares of Purchaser Shares will be issued and any holder of
Company Shares entitled pursuant to this Agreement to receive a fraction of a
share of Purchaser Shares but for this Section 2.05 will be entitled only to
receive the number of shares of Purchaser Shares to be issued to each such
Shareholder rounded to the nearest whole share. With respect to any delivery of
Purchaser Shares to Option Holders upon the exercise of Purchaser Options, no
fractional shares of Purchaser Shares will be issued and any Option Holder
entitled to receive a fraction of a share of Purchaser Shares but for this
Section 2.05 will be entitled only to receive the number of shares of Purchaser
Shares to be issued upon such exercise rounded to the nearest whole share.

            SECTION 2.06. (a) PIGGY-BACK REGISTRATION. If, after the Closing
Date Purchaser proposes to register any Purchaser Common Stock under the
Securities Act for sale to the public, whether for its own account or for the
account of other security holders or both (except pursuant to a registration
statement on Form S-4 or S-8 (or any substitute form adopted by the SEC) or any
other form that does not permit the inclusion of shares by its security
holders), Purchaser will give written notice to the Investors of its intention
to do so and, upon the written request of any such Investor given within ten
(10) days after receipt of any such notice (which request shall specify the
number of Purchaser Shares intended to be sold or disposed of by such Investor
up to the maximum number of shares set forth opposite the name of such Investor
on SCHEDULE I hereto under the heading "Registrable Shares"), Purchaser will use
its commercially reasonable efforts to cause up to 250,000 Purchaser Shares that
such Investors shall have requested the registration of to be included in such
notification or the registration statement proposed to be filed by Purchaser;
provided, however, that nothing herein shall prevent Purchaser from, at any
time, abandoning, delaying or suspending the effectiveness of any such
registration; and provided further, however, that nothing contained herein shall
require Purchaser to take any action which would violate the provisions of any
existing agreements relating to registration rights. If any such registration
shall be underwritten in whole or in part, Purchaser may require the Purchaser
Shares requested for inclusion pursuant to this Section 2.06 to be included in
the underwriting on the same terms and conditions as the securities otherwise
being sold through the underwriters. The number of Purchaser Shares to be
included in such an underwriting may be reduced (pro rata among the requesting
holders (other than Purchaser and any other persons demanding registration
pursuant to currently existing rights who are entitled to be protected against
any such reduction) based upon the number of shares so requested to be
registered; provided that, solely for the purposes of calculating the pro rata
reduction, the number of shares requested to be registered by the Investors
shall be deemed to be 4,000,000) if and to the extent that (1) the total number
of shares requested to be registered in such registration exceeds 250,000 or (2)
the managing underwriter shall be of the good faith opinion that such inclusion
would adversely affect the marketing of the securities to be sold by Purchaser.
All expenses of such offering, except the brokers' commissions or underwriting
discounts payable by the Investors, shall be borne by Purchaser.

            (b)   INDEMNIFICATION. (i) In connection with any such registration
      effected pursuant to Section 2.06(a) hereof, to the extent permitted by
      law, Purchaser will, and hereby does, indemnify and hold harmless, each
      Investor (such term to include each director and officer of such Investor
      and each other person, if any, who controls such Investor within the
      meaning of the Securities Act or the Exchange Act solely for


                                       8
<PAGE>

      purposes of this Section 2.06(b)(i)) against any losses, claims, damages
      or liabilities to which such Investor may become subject under the
      Securities Act or otherwise, insofar as such losses, claims, damages or
      liabilities (or actions or proceedings, whether commenced or threatened,
      in respect thereof) arise out of or are based upon any untrue statement or
      alleged untrue statement of any material fact contained in any
      registration statement under which such securities are registered under
      the Securities Act, and preliminary prospectus, final prospectus or
      summary prospectus contained therein, or any amendment or supplement
      thereto, or any omission or alleged omission to state therein 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, and Purchaser will reimburse each of the Investors for any
      legal or any other expenses reasonably incurred by it in connection with
      investigating or defending any such loss, claim, liability, action or
      proceeding; provided, however, that Purchaser shall not be liable in any
      such case to the extent that any such loss, claim, damage, liability (or
      action or proceeding in respect thereof) or expense arises out of or is
      based upon an untrue statement or alleged untrue statement or omission or
      alleged omission made in such registration statement, any such preliminary
      prospectus, final prospectus, summary prospectus, amendment or supplement
      in reliance upon and in conformity with written information furnished to
      Purchaser through an instrument duly executed by or on behalf of the
      Investors specifically stating that it is for use in the preparation
      thereof; and provided further, however, that Purchaser shall not be liable
      to any of the Investors, in any such case to the extent that any such
      loss, claim, damage, liability (or action or proceeding in respect
      thereof) or expense arises out of such Shareholder's failure to send or
      give a copy of the final prospectus, as the same may be then supplemented
      or amended, to the person asserting an untrue statement or alleged untrue
      statement or omission or alleged omission at or prior to the written
      confirmation of the sale of Purchaser Shares to such person if such
      statement or omission was corrected in such final prospectus and copies of
      such final prospectus were delivered to the Investors prior to the written
      confirmation of the sale of Purchaser Shares to such person asserting an
      untrue statement or alleged untrue statement or omission or alleged
      omission. Such indemnity shall remain in full force and effect regardless
      of any investigation made by or on behalf of the Investors and shall
      survive the transfer of such securities by the Investors.

            (ii)  Purchaser may require, as a condition to including any
      Purchaser Shares in any registration statement filed pursuant to this
      Section 2.06, that Purchaser shall have received an undertaking
      satisfactory to it from the Investors holding such Purchaser Shares, to
      indemnify and hold harmless (in the same manner and to the same extent as
      set forth in this Section 2.06) Purchaser, each director of Purchaser,
      each officer of Purchaser and each other person, if any, who controls
      Purchaser within the meaning of the Securities Act or the Exchange Act,
      with respect to any statement or alleged statement in or omission or
      alleged omission from such registration statement, any preliminary
      prospectus, final prospectus or summary prospectus contained therein, or
      any amendment or supplement thereto, if such statement or alleged
      statement or omission or alleged omission was made in reliance upon and in
      conformity with written information furnished to Purchaser through an
      instrument duly executed by the Investors specifically stating that it was
      for use in the preparation of such registration statement,


                                       9
<PAGE>

      preliminary prospectus, final prospectus, summary prospectus, amendment or
      supplement; provided, however, that the amount of any claim by Purchaser
      against any Investor for indemnification under this Section 2.06(b)(ii)
      shall be limited to the net proceeds received by such Investor from the
      sale of the Purchaser Shares included in such registration. Such indemnity
      shall remain in full force and effect, regardless of any investigation
      made by or on behalf of Purchaser or any such director, officer or
      controlling person and shall survive the transfer of such securities by
      the Investors.

            (c)   CONTRIBUTION. If for any reason the foregoing indemnity is
unavailable, then the indemnifying party shall contribute to the amount paid or
payable by the indemnified party as a result of such losses, claims, damages,
liabilities or expenses (i) in such proportion as is appropriate to reflect the
relative benefits received by the indemnifying party on the one hand and the
indemnified party on the other, or (ii) if the allocation provided by
subdivision (i) above is not permitted by applicable law or provides a lesser
sum to the indemnified party than is appropriate to reflect not only the
relative benefits received by the indemnifying party on the one hand and the
indemnified party on the other but also the relative fault of the indemnifying
party and the indemnified party as well as any other relevant equitable
considerations, then in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and the indemnified party as well as
any other equitable considerations. Notwithstanding the foregoing, neither party
shall be required to contribute any amount in excess of the amount the
indemnifying party would have been required to pay to an indemnified party if
the indemnity under this Section 2.06 was available. 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.

                                      III.

                      REPRESENTATIONS AND WARRANTIES AS TO
                                   THE COMPANY

            The Company represents and warrants to the Purchaser, subject to the
exceptions specifically disclosed in writing in the Company Disclosure Schedule,
all such exceptions to be referenced to a specific representation set forth in
this Article III, that:

            SECTION 3.01. ORGANIZATION AND QUALIFICATION; NO SUBSIDIARIES. (a)
The Company has been duly organized and is validly existing under the Laws of
the jurisdiction of its incorporation and there are no proceedings to strike the
Company from the Registrar of Companies and the Company has the requisite
corporate power and authority to own, lease and operate its properties and to
carry on its business as it is now being conducted (the "BUSINESS"). The Company
is duly qualified or licensed to do business, and is in good standing, in each
jurisdiction where the character of the properties owned, leased or operated by
it or the nature of its business makes such qualification or licensing
necessary, except for such failures to be so qualified or licensed and in good
standing that could not reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect.

            (b) The Company does not own an equity interest in any corporation,
partnership or joint venture arrangement or other business entity.


                                       10

            SECTION 3.02. MEMORANDUM AND ARTICLES OF ASSOCIATION. True, complete

Disclosure Schedule. Such Charter and Bylaws are in full force and effect. The
Company is not in violation of any of the provisions of its Charter or Bylaws.

            SECTION 3.03. CAPITALIZATION. The authorized capital stock of the
Company consists of 3,800,000 shares of Company Capital Stock. As of the date

all of which are duly authorized, validly issued, fully paid and nonassessable.
Except for the Company Capital Stock, there are no shares of capital stock or
other equity securities of the Company outstanding. Except as set forth on

contractual obligations of the Company to repurchase, redeem or otherwise
acquire any shares of Company Capital Stock. There are no material outstanding
contractual obligations of the Company to provide funds to, or make any material
investment (in the form of a loan, capital contribution or otherwise) in, any

            SECTION 3.04. AUTHORITY RELATIVE TO THIS AGREEMENT. The Company has
all necessary corporate power and authority to execute and deliver this
Agreement and all other instruments, certificates and agreements delivered or
required to be delivered by the Shareholders, the Company, the Purchaser or any
of their representatives pursuant to this Agreement (the "TRANSACTION
Documents") to which the Company is a party, to perform its obligations
hereunder and thereunder and to consummate the transactions contemplated hereby
and thereby. The execution and delivery of this Agreement and the other
Transaction Documents to which it is a party by the Company and the consummation
by the Company of the transactions contemplated hereby and thereby have been
duly and validly authorized by all necessary corporate action, and no other
corporate proceedings on the part of the Company are necessary to authorize this
Agreement or such Transaction Documents or to consummate the transactions
contemplated hereby and thereby. This Agreement and the other Transaction
Documents to which it is a party have been duly and validly executed and
delivered by the Company. Assuming the due authorization, execution and delivery
by the other parties hereto and thereto, each of this Agreement and the other
Transaction Documents to which it is a party constitutes the legal, valid and
binding obligation of the Company, enforceable against it in accordance with its
terms, except to the extent that its enforceability may be limited by applicable
bankruptcy, insolvency, reorganization or other Laws affecting the enforcement
of creditors' rights generally or by general equitable principles.

            SECTION 3.05. NO CONFLICTS; REQUIRED FILINGS AND CONSENTS. (a) The
execution and delivery of this Agreement and the other Transaction Documents to
which it is a party by the Company do not, and the performance by the Company of

Disclosure Schedule, result in any breach of or constitute a default (or an
event which with the giving of notice or lapse of time or both could reasonably
be expected to become a default) under, or give to others any right of
termination, amendment, acceleration or cancellation of, or result in the
creation of a lien or other encumbrance on any material property or asset of the
Company pursuant to, any material note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation.

            (b)   Other than the filing of a Share Transfer Report with the
Companies Registrar of the State of Israel following the Closing, no filing or
registration with, or notification to, and no permit, authorization, consent or
approval of, any Government Entity (including, but not limited to, the consent
of the Office of the Chief Scientist of the Israeli Ministry of Industry and
Trade) is necessary for the execution and delivery of this Agreement by the
Company or the consummation by the Company of the transactions contemplated by
this Agreement except such filings, registrations, notices, permits,
authorizations, consents and approvals that if not obtained, made or given would
not, individually or in the aggregate, have a Company Material Adverse Effect or
impair the Company's ability to consummate the transactions contemplated hereby.

            (c)   Except as set forth in Section 3.05(c) of the Company
Disclosure Schedule, no consent of any third party is required by reason of the
transactions contemplated by this Agreement.

            SECTION 3.06. PERMITS; COMPLIANCE WITH LAWS. Except as set forth in
Section 3.06 of the Company Disclosure Schedule, the Company is in possession of
all material franchises, grants, authorizations, licenses, establishment
registrations, product listings, permits, easements, variances, exceptions,
consents, certificates, identification and registration numbers, approvals and
orders of any Governmental Entity necessary for the Company to own, lease and
operate its properties or to offer or perform its services or to develop,
produce, store, distribute and market its products or otherwise to carry on its
business as it is now being conducted (collectively, the "COMPANY Permits"),
and, as of the date of this Agreement, none of the Company Permits has been
suspended or cancelled nor is any such suspension or cancellation pending or, to
the knowledge of the Company and each of the Shareholders, threatened. The
Company is not in conflict with, or in default or violation of, (i) any material
Law applicable to the Company or by which any property or asset of the Company
is bound or affected or (ii) any Company Permits. Section 3.06 of the Company
Disclosure Schedule sets forth, as of the date of this Agreement, all actions,
proceedings, investigations or surveys pending or, to the knowledge of the
Company and each of the Shareholders, threatened against the Company or the
Business that could reasonably be expected to result in the suspension or
cancellation of any other Company Permit. The Company has not received from any
Governmental Entity any written notification with respect to possible conflicts,
defaults or violations of Laws. The transactions contemplated hereby will not
result in the suspension or cancellation of any Company Permit.

            SECTION 3.07. FINANCIAL STATEMENTS. (a) Section 3.07 of the Company
Disclosure Schedule includes copies of (i) the audited balance sheet of the
Company at December 31, 1999, together with the related statement of operations,

on a consistent basis throughout the periods covered thereby; (ii) present
fairly the financial position, results of operations and cash flows of the
Company as of such dates and for the periods then ended (subject, in the case of

reconciled with the books of account and records of the Company. The Company
maintains and will continue to maintain until the Closing an adequate system of
internal controls established and administered in accordance with Israeli GAAP.

            (b) Except as and to the extent set forth or reserved against on the
balance sheets of the Company as reported in the Company Financial Statements,
the Company does not have any liabilities or obligations of any nature (whether
accrued, absolute, contingent or otherwise) that would be required to be
reflected on a balance sheet or in notes thereto prepared in accordance with
Israeli GAAP, except for liabilities or obligations incurred in the ordinary
course of business consistent with past practice since June 30, 2000.

            SECTION 3.08. ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as set
forth in Section 3.08 of the Company Disclosure Schedule or as stated on the
unaudited interim balance sheet of the company at June 30, 2000, since December
31, 1999, the Company has conducted its business only in the ordinary course
consistent with past practice and, since such date, there has not been (i) any

business consistent with past practice, any (x) purchase, sale, assignment or
transfer of any material assets, (y) mortgage, pledge or existence of any lien,
encumbrance or charge on any material assets or properties, tangible or
intangible, except for liens for Taxes not yet delinquent and such other liens,
encumbrances or charges which do not, individually or in the aggregate, have a
Company Material Adverse Effect, or (z) waiver of any rights of material value
or cancellation or any material debts or claims, (ix) any incurrence of any
material liability (absolute or contingent), except for current liabilities and
obligations incurred in the ordinary course of business consistent with past
practice, (x) any incurrence of any damage, destruction or similar loss, whether
or not covered by insurance, materially affecting the business or properties of
the Company, (xi) any entering into any transaction of a material nature other
than in the


                                       13
<PAGE>

ordinary course of business, consistent with past practice, or (xii) any current
negotiation (or, with respect to clauses (ii), (iii), (iv) or (vii) any
negotiation, whether past or current) or any agreement by the Company to do any
of the things described in the preceding clauses (i) through (xi).

            SECTION 3.09. EMPLOYEE MATTERS. (a) The Company is not party to any
Contract regarding collective bargaining or other Contract with any labor or
trade union or collective bargaining group representing any employee of the
Company, nor does any labor or trade union or collective bargaining agent
represent any employee of the Company. No Contract regarding collective
bargaining has been requested by, or is under discussion between management of
the Company (or any management group or association of which the Company is a
member or otherwise a participant) and any group of employees of the Company,
nor are there any representation proceedings or petitions seeking a
representation proceeding presently pending against the Company, nor, to the
knowledge of the Company and the Shareholders, are there any other current
activities to organize any employees of the Company into a collective bargaining
unit. The Company is not subject to, nor do any of its employees benefit from,
any collective bargaining agreement by way of any applicable employment laws and
regulations and extension orders ("TZAVEI HARCHAVA"), other than tzavei harchava
applying generally to all employers in Israel or to all employees in the
Company's field of business. Except as set forth in Section 3.09(a) of the
Company Disclosure Schedule, the Company has no custom with respect to
termination of employment. There are no unfair labor practice charges or
complaints pending or, to the knowledge of the Company and the Shareholders,
threatened against the Company.

            (b)   Schedule 3.09(b) sets forth a true, accurate and complete list
of the Company's directors, officers, employees, consultants and independent
contractors, and includes a listing of each of such director's, officer's and
employee's compensation terms (including, but not limited to date of
commencement of employment, salary, bonuses, stock options and warrants (if
any), fringe benefits and accrued vacation). All the employees of the Company
reside and work in Israel. The Company is not delinquent in any material payment
to any of its employees for any wages, salaries, commissions, bonuses or other
direct compensation for any services performed by any such employees. Except as
indicated in Schedule 3.09(b), upon termination of the employment of any
employees, neither the Company nor the Purchaser will by reason of the
transaction contemplated pursuant to this Agreement or anything done prior to
the Closing Date be liable to any of such directors, officer or employees for
severance pay or any other payments beyond any amounts reserved for on the
Company Financial Statements.

            (c)   The Company has previously delivered to Purchaser true and
complete copies of all employment, consulting, termination and severance
Contracts (whether written or oral) with or for the benefit of, or otherwise
relating to, any directors, officers, employees, consultants or independent
contractors of the Company. Except as set forth on Schedule 3.09(c), none of the
execution, delivery or performance of any Transaction Document or the
consummation of the transactions contemplated hereby or thereby will result in
any obligation to pay any directors, officers, employees, consultants,
independent contractors, former directors, officers, employees, consultants or
independent contractors of the Company severance pay or termination, retention
or other benefits.


                                       14
<PAGE>

            (d)   Except as set forth on Schedule 3.09(d), no employee has given
notice to, or received notice from, the Company or any of its Representatives
that any such employee's employment or service may be terminated or advised the
Company of an intention to give such notice to, or is expected to receive notice
from, the Company or any of its Representatives that any such employee's
employment or service may be terminated.

            (e)   Each compensation and benefit plan required to be maintained
or contributed to by the law or applicable custom or rule of the relevant

opposite the name of such Shareholder in SCHEDULE I to this Agreement under the
heading "Company Shares," in each case free and clear of any and all pledges,
security interests, liens, charges or other encumbrances of any nature
whatsoever, other than as imposed by the Company's Bylaws and waived pursuant to
Section 10.04 hereof. The delivery by each Shareholder of certificates or
instruments and agreements evidencing the number of Company Shares set forth

approving such transfer of shares and registering transfer in the Company's

from such registration is available. Each Shareholder hereby agrees and

of any of the Purchaser Shares except in a transaction that is the subject of
either (i) an effective registration statement under the Securities Act and any

transactions contemplated by this Agreement and each Shareholder has the ability
to bear the economic risks of such Shareholder's investment in the Purchaser
Shares for an indefinite period of time. Each

from, officers of the Purchaser with respect to the business and financial
condition of the Purchaser and the terms and conditions of the offering of the

            SECTION 6.06. CERTAIN TAX MATTERS. (a) TAXES. Each party will, at
its own expense, file all necessary Tax Returns and other documentation with
respect to all Taxes and fees incurred at Closing, as required by applicable
law. The Purchaser will, and will cause its Affiliates to, join in the execution
of any such Tax Returns and other documentation.

            (b)   TAX RETURNS. The following provisions shall govern the
allocation of responsibility as between the Purchaser and the Shareholders for
certain tax matters following the Closing Date:

            (i)   TAX PERIODS ENDING ON OR BEFORE THE CLOSING DATE. The
      Purchaser shall prepare or cause to be prepared and file or cause to be
      filed all Tax Returns for the Company and its Subsidiaries for all periods
      ending on or prior to the Closing Date which are filed after the Closing
      Date. The Purchaser shall permit the Shareholders to review and comment on
      each such Tax Return described in the preceding sentence prior to filing.
      The Shareholders shall reimburse the Purchaser for Taxes of the Company
      with respect to such periods within fifteen (15) days after payment by the
      Purchaser or the Company of such Taxes to the extent such Taxes are not
      reflected in the reserve for Tax liability (rather than any reserve for
      deferred Taxes established to reflect timing differences between book and
      Tax income) shown on the face of the Company's balance sheet as of June
      30, 2000.

            (ii)  TAX PERIODS BEGINNING BEFORE AND ENDING AFTER THE CLOSING
      DATE. The Purchaser shall prepare or cause to be prepared and file or
      cause to be filed any Tax Returns of the Company for Tax periods which
      begin before the Closing Date and end after the Closing Date. The
      Shareholders shall pay to the Purchaser within fifteen (15) days after the
      date on which Taxes are paid with respect to such periods an amount equal
      to the portion of such Taxes which relates to the portion of such Taxable
      period ending on the Closing Date to the extent such Taxes are not
      reflected in the reserve for Tax liability (rather than any reserve for
      deferred Taxes established to reflect timing differences between book and
      Tax income) shown on the face of the Company's balance sheet as of June
      30, 2000. For purposes of this Section, in the case of any Taxes that are
      imposed on a periodic basis and are payable for a Taxable period that
      includes (but does not end on) the Closing Date, the portion of such Tax
      which relates to the portion of such Taxable period ending on the Closing
      Date shall (x) in the case of any Taxes other than Taxes based upon or
      related to income or receipts, be deemed to be the amount of such Tax for
      the entire Taxable period multiplied by a fraction the numerator of which
      is the number of days in the Taxable period ending on the Closing Date and
      the denominator of which is the number of days in the entire Taxable
      period, and (y) in the case of any Tax based upon or related to income or
      receipts be deemed equal to the amount which would be payable if the
      relevant Taxable period ended on the Closing Date. Any credits relating to
      a Taxable period that begins before and ends after the Closing Date shall
      be taken into account as though the relevant Taxable period ended on the
      Closing Date. All determinations necessary to give effect to the foregoing
      allocations shall be made in a manner consistent with prior practice of
      the Company and its Subsidiaries.


                                       33

            (iii) COOPERATION ON TAX MATTERS. The Purchaser, the Company and the
      Shareholders shall cooperate fully, as and to the extent reasonably
      requested by the other party, in connection with the filing of Tax Returns
      pursuant to this Section and any audit, litigation or other proceeding
      with respect to Taxes. Such cooperation shall include the retention and
      (upon the other party's request) the provision of records and information
      which are reasonably relevant to any such audit, litigation or other
      proceeding and making employees available on a mutually convenient basis
      to provide additional information and explanation of any material provided
      hereunder. The Company, the Purchaser and the Shareholders agree (A) to
      retain all books and records with respect to Tax matters pertinent to the
      Company relating to any taxable period beginning before the Closing Date
      until the expiration of the statute of limitations (and, to the extent
      notified by the Purchaser or the Shareholders, any extensions thereof) of
      the respective taxable periods, and to abide by all record retention
      agreements entered into with any taxing authority, and (B) to give the
      other party reasonable written notice prior to transferring, destroying or
      discarding any such books and records and, if the other party so requests,
      the Company, the Purchaser or the Shareholders, as the case may be, shall
      allow the other party to take possession of such books and records. The
      Company, the Purchaser and the Shareholders agree that the Shareholders
      shall not be responsible after the Closing Date for the maintenance and
      retention of the Company's books and records which are pertinent to Tax
      matters and which have already been provided to, or are otherwise in the
      possession of, the Company, and shall not be responsible for the Company's
      books and records relating to the period after the Closing Date.

            (iv)  The Purchaser and the Shareholders further agree, upon
      request, to use their reasonable efforts to obtain any certificate or
      other document from any governmental authority or any other Person as may
      be necessary to mitigate, reduce or eliminate any Tax that could be
      imposed (including, but not limited to, with respect to the transactions
      contemplated hereby).

            (v)   The Purchaser and the Shareholders further agree, upon
      request, to provide the other party with all information that either party
      may be required to report pursuant to Section 6043 of the Code and all
      Treasury Department Regulations promulgated thereunder.

            (c)   TAX SHARING AGREEMENTS. All tax sharing agreements or similar
agreements with respect to or involving the Company shall be terminated as of
the Closing Date and, after the Closing Date, the Company shall not be bound
thereby or have any liability thereunder.

            SECTION 6.07. PUBLIC ANNOUNCEMENTS. Until the earlier of termination
of this Agreement or the Closing Date, the Purchaser, on the one hand, and the
Company and the Shareholders, on the other hand, will consult with each other
before issuing any press release or otherwise making any public statements with
respect to the Agreement or the transactions contemplated hereby and shall not
issue any such press release or make any such public statement that is not
approved by the other party, except as may be required by Law or the rules of
the Nasdaq National Market, in which case the parties will make reasonable
efforts to consult with each other prior to the making of such public statement.

            SECTION 6.08. LOCK-UP AGREEMENT OF SHAREHOLDERS. Each Shareholder
agrees in connection with any registered underwritten public offering of the
Purchaser Common Stock in which the Investors register any shares pursuant to
Section 2.06 hereof, upon request of the underwriters managing an underwritten
public offering, not to sell, make any short sale of, loan, grant any option for
the purchase of or otherwise dispose of any shares of Purchaser Common Stock
(other than those, if any, that are included in the public offering) without the
prior written consent of the Purchaser or such underwriters, as the case may be,
for such period of time as may be requested by the underwriters, PROVIDED that
the officers and directors of the Purchaser and other shareholders of the
Purchaser selling shares in such offering shall also enter into such an
agreement.

            SECTION 6.09. CASH ON HAND; INDEBTEDNESS AND LIABILITIES. As of the
Closing Date, the assets that would be reflected as cash, cash equivalents and
immediately collectible accounts receivable on the Company's balance sheet under
Israeli GAAP minus all current and long term liabilities under Israeli GAAP
(excluding liability for employee rights under retirement) and other
Indebtedness of the Company shall equal at least $500,000 minus current and long
term liabilities and other Indebtedness incurred by the Company in the ordinary
course of business between October 1, 2000 and the Closing Date, which
subtracted amount shall not exceed $75,000.

            SECTION 6.10. LEGEND. Each stock certificate evidencing shares of
Purchaser Common Stock shall bear the following legend:

      "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD,
      TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE
      OF (i) AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SECURITIES UNDER SAID
      ACT OR (ii) AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH
      REGISTRATION IS NOT REQUIRED UNDER SUCH ACT."

                                      VII.

                                 INDEMNIFICATION

            SECTION 8.01. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The
representations and warranties set forth in Articles II, III and IV, other than
Section 3.03 (CAPITALIZATION), Section 3.14 (TAXES), and Section 4.03 (TITLE TO

the applicable statute of limitations, will


                                       38
<PAGE>

survive until the first anniversary of the Closing Date. This Section 8.01 shall
not limit any covenants or agreements of the parties hereto that by their terms
contemplated performance after the Closing Date.

            SECTION 8.02. TAX INDEMNITY. (a) The Shareholders jointly and
severally agree to and will (except, with respect to any Taxes incurred by,
imposed on or attributable to the Shareholders, the Shareholders agree to and
will, severally and not jointly) indemnify, defend and hold harmless the
Purchaser and the Company, and their respective officers, directors, advisors,
Affiliates, agents, employees and each Person, if any, who controls or may
control the Purchaser within the meaning of the Securities Act (the "PURCHASER
INDEMNIFIED GROUP") from and against any and all Taxes incurred by, imposed upon
or attributable to the Company or the Shareholders (and from and against any and
all Taxes incurred by, imposed upon or attributable to the Company or the
Shareholders as a result of the indemnity provided for in this Section 8.02),
including without limitation reasonable legal fees and expenses incurred by the
Company or any party hereto and relating thereto, for any period (or portion
thereof) prior to or ending on the Closing Date to the extent that such Taxes
were not reflected on the Company Financial Statements as a reserve for the
payment of Taxes for the period (or portion thereof) ending on or prior to the
Closing Date, including without limitation any amount due for sales and use
Taxes payable as a result of an audit conducted by state or local governmental
authorities or any amount due with respect to withholding Taxes.

            (b)   For purposes of this Section 8.02, any interest, penalty or
additional charge included in Taxes shall be deemed to be a Tax for the period
to which the item or event giving rise to such interest, penalty or additional
charge is attributable, and not a Tax for the period during which such interest,
penalty or additional charge accrues.

            (c)   The indemnity provided for in this Section 8.02 shall be
independent of any other indemnity provision hereof and, anything in this
Agreement to the contrary notwithstanding, shall survive until the expiration of
the applicable statutes of limitation, including any extensions thereof, for the
Taxes referred to herein. Any Taxes, legal fees and expenses subject to
indemnification under this Section 8.02 shall not be subject to indemnification
under Section 8.03 hereof.

            SECTION 8.03. GENERAL INDEMNITY. (a) Subject to the terms and
conditions of this Article VIII, the Shareholders agree to and will, jointly and
severally (except, in the event that the amounts held in the Escrow Fund are
less than any Damages resulting from a breach of Section 4.03, as to which the
Shareholders agree to and will, severally but not jointly as to such excess,)
indemnify, defend and hold the Purchaser and its officers, directors, advisors,
Affiliates, agents, employees and each Person, if any who controls or may
control the Purchaser within the meaning of the Securities Act (each, an
"Indemnified Person") harmless from and against all demands, claims, actions or
causes of action, assessments, losses, damages, liabilities, costs and expenses,
including without limitation interest, penalties and reasonable attorneys' fees
and expenses (hereinafter collectively called "DAMAGES"), asserted against,
resulting to, imposed upon or incurred by the Company, the Purchaser or any
Indemnified Person, by reason of, resulting from or arising out of:


                                       39
<PAGE>

            (i) a breach of any representation or warranty of the Company or any
      Shareholder contained in or made pursuant to this Agreement, or any facts
      or circumstances constituting such a breach, except as and to the extent
      that Section 8.02 above shall be applicable thereto, in which case the
      provisions of said Section 8.02 shall govern;

            (ii) any breach of any covenant or agreement of the Company or any
      Shareholder contained in or made pursuant to this Agreement or the Escrow
      Agreement; and

            (iii) any facts or events described in the Company Disclosure
      Schedule as specifically intended to be subject to this Article 8, whether
      or not such fact or event would be deemed a breach of any representation,
      warranty, covenant or agreement contained in or made pursuant to this
      Agreement.

            For the avoidance of doubt, the Shareholders have agreed to jointly
and severally indemnify the Indemnified Persons pursuant to this section for the
breaches described in (i) and (ii) above whether the breach is by the Company or
the Shareholder and without regard to whether the representation is made solely
by the Company or the covenant by its terms binds only the Company.

            (b)   Subject to the terms and conditions of this Article VIII, the
Purchaser agrees to and will indemnify, defend and hold the Shareholders and
each of their respective officers, directors, advisors, Affiliates, agents,
employees and each Person, if any who controls or may control each of the
Shareholders within the meaning of the Securities Act (each, a "Shareholder
Indemnified Person") harmless from and against all Damages asserted against,
resulting to, imposed upon or incurred by them by reason of or resulting from or
arising out of (i) a breach of any representation or warranty of the Purchaser
contained in or made pursuant to this Agreement, or any facts or circumstances
constituting such a breach, or (ii) any breach of any covenant or agreement of
the Purchaser contained in or made pursuant to this Agreement or the Escrow
Agreement.

            SECTION 8.04. CONDITIONS OF INDEMNIFICATION. The respective
obligations and liabilities of the Shareholders, on the one hand, and the
Purchaser, on the other hand (herein sometimes called the "INDEMNIFYING PARTY"),
to the other or any other Indemnified Person or Shareholder Indemnified Person
(herein sometimes called the "PARTY TO BE INDEMNIFIED" or the "INDEMNIFIED
PARTY") under Section 8.03 hereof with respect to claims resulting from the
assertion of liability by third parties shall be subject to the following terms
and conditions:

            (a)   within 30 days (or, if earlier, by the fifteenth day preceding
      the day on which an answer or other pleading must be served in order to
      prevent judgment by default in favor of the Person asserting such claim,
      unless an extension is available to extend such deadline) after receipt of
      notice of commencement of any action or the assertion of any claim by a
      third party, the party to be indemnified shall give the indemnifying party
      written notice thereof together with a copy of such claim, process or
      other legal pleading (provided that failure so to notify the indemnifying
      party of the assertion of a claim within such period shall not affect its
      indemnity obligation hereunder


                                       40
<PAGE>

      except as and to the extent that such failure shall adversely affect the
      defense of such claim), and the indemnifying party shall have the right to
      undertake the defense thereof by representatives of its own choosing;

            (b)   in the event that the indemnifying party, by the 30th day
      after receipt of notice of any such claim (or, if earlier, by the tenth
      day preceding the day on which an answer or other pleading must be served
      in order to prevent judgment by default in favor of the Person asserting
      such claim, unless an extension is available to extend such deadline),
      does not elect to defend against such claim, the party to be indemnified
      will (upon further notice to the indemnifying party) have the right to
      undertake the defense, compromise or settlement of such claim on behalf of
      and for the account and risk of the indemnifying party, subject to the
      right of the indemnifying party to assume the defense of such claim at any
      time prior to settlement, compromise or final determination thereof;

            (c)   anything in this Section 8.04 to the contrary notwithstanding,
      (i) if there is a reasonable probability that a claim may materially and
      adversely affect the indemnified party other than as a result of money
      damages or other money payments, the indemnified party shall have the
      right, at its own cost and expense, to compromise or settle such claim,
      but (ii) the indemnified party shall not, without the prior written
      consent of the indemnifying party, settle or compromise any claim or
      content to the entry of any judgment which does not include as an
      unconditional term thereof the giving by the claimant or the plaintiff to
      the indemnifying party a release from all liability in respect of such
      claim; and

            (d)   in connection with any such indemnification, the indemnified
      party will cooperate in all reasonable requests of the indemnifying party.

In the event that the "indemnifying party" or the "party to be indemnified" as
described in this Section 8.04 is the Shareholders as a group, then any notices
required to be given to or by, and all other actions or decisions required to be
taken or made by, such "indemnifying party" or the "party to be indemnified" as
provided in this Section 8.04, may be given to or by, or may be taken or made
by, the Shareholder Representative (as defined in the Escrow Agreement).

            SECTION 8.05. THRESHOLD FOR DAMAGES. Notwithstanding the foregoing,
an Indemnified Person or Shareholder Indemnified Person may not make a claim for
Damages until the aggregate amount of claims by Indemnified Persons exceeds
$200,000; PROVIDED, HOWEVER, that once the aggregate amount of Damages of
Indemnified Persons or Shareholder Indemnified Persons exceed such threshold
amount, then the Indemnified Persons or Shareholder Indemnified Persons shall
have the right to recover the full amounts due without regard to the threshold.
In determining the amount of any Damage attributable to a breach, any
materiality standard contained in a representation, warranty or covenant of the
Shareholders or the Company shall be disregarded.

            SECTION 8.06. ESCROW FUND; EXCLUSIVE REMEDY. On the Closing Date,
the Purchaser shall deliver to the Escrow Agent the Escrow Fund. The Escrow Fund
shall be held by the Escrow Agent under the Escrow Agreement pursuant to the
terms set forth therein and shall be available to compensate Indemnified Persons
or the Purchaser Indemnified Group pursuant to


                                       41
<PAGE>

the indemnification obligations of the Shareholders; PROVIDED, HOWEVER, that the
parties expressly agree that the Escrow Fund is intended to be the exclusive
remedy and source of recovery of the Indemnified Persons and the Purchaser
Indemnified Group in connection with any breach of any representation, warranty,
covenant or agreement made by the Company or the Shareholders under this
Agreement, and recovery under the Escrow Agreement shall be the sole and
exclusive remedy hereunder, in each case except with respect to Sections 3.03,
3.14, 4.03 and 6.06, the breach of which is not intended to be so limited as to
remedies or recovery.

            SECTION 8.07. ESCROW PERIOD. The Purchaser shall release to the
Israeli Trustee (as defined in the Escrow Agreement) for the benefit of the
Shareholders on a PRO RATA basis any portion of the Escrow Fund remaining in
escrow on the first anniversary of the Closing Date (the "ESCROW PERIOD");
PROVIDED, HOWEVER, that a portion of the Escrow Fund that is necessary to
satisfy any unsatisfied claims on the Escrow Fund prior to termination of the
Escrow Period with respect to facts and circumstances existing prior to
expiration of the Escrow Period, shall remain in escrow until such claims have
been resolved.

            SECTION 8.08. CLAIMS UPON ESCROW. Upon delivery to the Shareholders
on or before the last day of the Escrow Period of a certificate signed by any
officer of the Purchaser (an "OFFICER'S CERTIFICATE"):

            (i)   stating that Damages exist in an aggregate amount greater than
      $200,000; and

            (ii)  specifying in reasonable detail the individual items of such
      Damages included in the amount so stated, the date each such item was
      paid, or properly accrued or arose, and the nature of the
      misrepresentation or breach of representation, warranty, covenant or
      agreement made by the Company or the Shareholders under this Agreement,

the Escrow Agent (as defined in the Escrow Agreement) shall, subject to the
provisions of Sections 8.09 and 8.10 hereof, remove for the benefit of the
Purchaser, or the benefit of the other Indemnified Persons, a portion of the
Escrow Fund having a value equal to such Damages in accordance with the Escrow
Agreement. The value of the Escrow Shares shall be deemed to be seven dollars
($7.00) per share, with appropriate adjustment to take into account any stock
split, reverse stock split, stock dividend, recapitalization or other similar
capital adjustment with respect to Purchaser Common Stock

            SECTION 8.09. OBJECTIONS TO CLAIMS. At the time of delivery of any
Officer's Certificate to the Shareholders and for a period of thirty (30) days
after delivery to the Shareholders of such Officer's Certificate, the Escrow
Agent shall not remove for the benefit of any Indemnified Person any portion of
the Escrow Fund unless it shall have received written authorization from the
Shareholders to make such delivery. After the expiration of such thirty (30) day
period, the Escrow Agent shall remove for the benefit of any Indemnified Person
the appropriate portion of the Escrow Fund in accordance with Section 8.06
hereof, provided that no such delivery may be made if the Shareholders shall
object in a written statement to the claim made in the Officer's Certificate,
and such statement shall have been delivered to the Purchaser prior to the
expiration of such thirty (30) day period.


                                       42

            SECTION 8.10. RESOLUTION OF CONFLICTS; ARBITRATION. (a) In case the
Shareholders shall so object in writing to any claim or claims by the Purchaser
made in any Officer's Certificate, the Purchaser shall have thirty (30) days
after receipt of an objection by the Shareholders to respond in a written
statement to the objection of the Shareholders. If after such thirty (30) day
period there remains a dispute as to any claims, the Shareholders and the
Purchaser shall attempt in good faith for forty-five (45) days to agree upon the
rights of the respective parties with respect to each of such claims. If the
Shareholders and the Purchaser should so agree, a memorandum setting forth such
agreement shall be prepared and signed by both parties.

            (b)   If no such agreement can be reached after good faith
negotiation, either the Purchaser or the Shareholders may, by written notice to
the other, demand arbitration of the matter unless the amount of the damage or
loss is at issue in pending litigation with a third party, in which event
arbitration shall not be commenced until such amount is ascertained or both
parties agree to arbitration; and in either such event the matter shall be
settled by arbitration conducted by three arbitrators. Within fifteen (15) days
after such written notice is sent, the Purchaser and the Shareholders shall each
select one arbitrator, and the two arbitrators so selected shall select a third
arbitrator. The decision of the arbitrators as to the validity and amount of any
claim in such Officer's Certificate shall be binding and conclusive upon the
parties to this Agreement.

            (c)   Judgment upon any award rendered by the arbitrators may be
entered in any court having jurisdiction. Any such arbitration shall be held in
the State of New York under the commercial rules then in effect of the American
Arbitration Association. For purposes of this Section 8.10, in any arbitration
hereunder in which any claim or the amount thereof stated in the Officer's
Certificate is at issue, the Purchaser shall be deemed to be the "Non-Prevailing
Party" unless the arbitrators award the Purchaser at least one-half (1/2) of the
amount in dispute, plus any amounts not in dispute; otherwise, the Shareholders
shall be deemed to be the Non-Prevailing Party. The Non-Prevailing Party to an
arbitration shall pay its own expenses, the fees of each arbitrator, the
administrative fee of the American Arbitration Association, and the expenses,
including without limitation, attorneys' fees and costs, reasonably incurred by
the other party to the arbitration.

                                       IX.

                           TERMINATION AND ABANDONMENT

            SECTION 9.01. TERMINATION. This Agreement may be terminated at any

            (a)   by the mutual consent of the Company, the Shareholders and the
      Purchaser;

            (b)   by the Purchaser, on the one hand, or the Company and the
      Shareholders, on the other hand, if the Closing shall not have occurred on
      or before October 15, 2000, or such later date as may be agreed upon by
      the parties hereto, PROVIDED, HOWEVER, that the right to terminate this
      Agreement under this clause (b) shall not be available to any


                                       43
<PAGE>

      party (a "DEFAULTING PARTY") whose failure to fulfill any obligation under
      this Agreement has been the cause of, or resulted in the failure of the
      Closing to occur on or before such date;

            (c)   by the Purchaser, upon a breach of any representation,
      warranty, covenant or agreement on the part of the Company or any
      Shareholder set forth in this Agreement, or if any representation or
      warranty of the Company shall have become untrue, incomplete or incorrect,
      in either case such that the conditions set forth in Section 7.02 would
      not be satisfied (a "TERMINATING COMPANY BREACH"); PROVIDED, HOWEVER, that
      if such Terminating Company Breach is curable by the Company through the
      exercise of its reasonable efforts within ten (10) days and for so long as
      the Company continues to exercise such reasonable efforts, the Purchaser
      may not terminate this Agreement under this Section 9.01(c); or

            (d)   by the Company or the Shareholders, upon breach of any
      representation, warranty, covenant or agreement on the part of the
      Purchaser set forth in this Agreement, or if any representation or
      warranty of the Purchaser shall have become untrue, incomplete or
      incorrect, in either case such that the conditions set forth in Section
      7.03 would not be satisfied (a "TERMINATING PURCHASER BREACH"); PROVIDED,
      HOWEVER, that if such Terminating Purchaser Breach is curable by the
      Purchaser through the exercise of its reasonable efforts within ten (10)
      days and for so long as the Purchaser continues to exercise such
      reasonable efforts, the Company or the Shareholders may not terminate this
      Agreement under this Section 9.01(d).

If the Closing shall not have occurred, or this Agreement shall not have been
terminated in accordance with this Section 9.01, by October 31, 2000, this
Agreement shall automatically terminate on said date, PROVIDED, HOWEVER, that
such termination shall not affect the liability hereunder of any Defaulting
Party.

            SECTION 9.02. PROCEDURE AND EFFECT OF TERMINATION. In the event of
termination of this Agreement and abandonment of the transactions contemplated
hereby by any or all of the parties pursuant to Section 9.01 above, written
notice thereof shall forthwith be given to the other parties to this Agreement

Section) and this Agreement (except for this Section and Sections 9.01 and
10.01, which shall continue) shall terminate and the transactions contemplated
hereby shall be abandoned, without further action by any of the parties hereto.
If this Agreement is terminated as provided in this Agreement:

            (a)   the parties hereto will promptly redeliver all documents, work
      papers and other material of any other party relating to the transactions
      contemplated hereby, whether obtained before or after the execution
      hereof, to the party furnishing the same; and

            (b)   no party shall have any liability or further obligation to any
      other party to this Agreement pursuant to this Agreement except as
      provided in this Article IX.

                                ESCROW AGREEMENT


            THIS ESCROW AGREEMENT (this "AGREEMENT") is entered into as of
October 12, 2000, by and among LivePerson, Inc., a Delaware corporation ("LP"),
First Union National Bank, as Escrow Agent (the "ESCROW AGENT"), HumanClick
Ltd., a private company organized under the laws of the State of Israel
("HUMANCLICK"), and Eitan Ron, as Shareholders' Agent, on behalf of each of the
Shareholders of HumanClick listed on Schedule A hereto (collectively, the
"SHAREHOLDERS").

            WHEREAS, LP, HumanClick and the Shareholders have entered into a
Stock Purchase Agreement dated as of October 12, 2000 (the "STOCK PURCHASE
AGREEMENT");

            WHEREAS, the Stock Purchase Agreement provides that an escrow
account will be established to secure various obligations of the Shareholders on
the terms and subject to the conditions set forth in the Stock Purchase
Agreement and set forth herein; and

            WHEREAS, LP, Escrow Agent, HumanClick and the Shareholders' Agent
(the "PARTIES") desire to establish the terms and conditions pursuant to which
such escrow account will be established and maintained.

            NOW, THEREFORE, the Parties hereto hereby agree as follows:

            1.   DEFINED TERMS. Capitalized terms used in this Agreement and not
otherwise defined shall have the meanings given them in the Stock Purchase
Agreement.

            2.   APPOINTMENTS. First Union National Bank hereby accepts its
appointment as Escrow Agent hereunder. LP hereby appoints its President and
Chief Executive Officer and its Executive Vice President, Chief Financial
Officer and Secretary to act, either jointly or individually, on behalf of LP
for all purposes hereunder (each, an "LP AGENT"). Each of the Shareholders has
heretofore appointed Eitan Ron as its agent and representative to act on behalf
of the Shareholders on all matters relating to this Agreement, upon the terms
and subject to the conditions hereinafter set forth (the "SHAREHOLDERS' AGENT").
The actions of an LP Agent or the Shareholders' Agent under or pursuant to this
Agreement shall be binding on LP and the Shareholders, respectively.

            3.   CONSENT OF SHAREHOLDERS. Pursuant to the Stock Purchase
Agreement, the Shareholders have consented to the establishment of this escrow
to secure certain obligations under Article VIII of the Stock Purchase Agreement
and certain other obligations in the manner set forth therein.

            4.   ESCROW AND INDEMNIFICATION.

                 (a) ESCROW OF SHARES OF PARENT COMMON STOCK. As soon as
reasonably practicable after the Effective Time, LP shall deposit, on behalf of
the Shareholders, with the Escrow Agent one or more certificates representing an
aggregate of twenty-five percent (25%) of the Purchaser Shares (the "ESCROW
SHARES") to be issued pursuant to Section 2.03 of the Stock Purchase Agreement,
issued in the name of the Escrow Agent in the respective amounts set forth on
Schedule A hereto. The Escrow Agent agrees to accept delivery of the Escrow
Shares and to hold the Escrow Shares in an escrow account (the "ESCROW
ACCOUNT"), on the terms and subject to the conditions of this Agreement. The
Escrow Account shall not be an interest bearing account.


<PAGE>

                 (b) DISTRIBUTIONS AND DIVIDENDS. All dividends and other
distributions on Escrow Shares or additional shares of capital stock issued on
or with respect to the Escrow Shares as a result of stock splits, stock
dividends or other similar capital adjustments to, or recapitalizations on, the
Escrow Shares shall be delivered by LP to the Escrow Agent and retained in the
Escrow Account subject to the terms hereof and shall constitute Escrow Shares.

                 (c) VOTING OF SHARES AND OTHER RIGHTS. All voting rights with
respect to Escrow Shares may be exercised by the Shareholders in accordance with
their proportionate interests therein, and the Escrow Agent shall from time to
time execute and deliver to the Shareholders such proxies, consents or other
documents as may be necessary to enable the Shareholders to exercise such
rights. In the absence of any exercise of such voting rights with respect to
Escrow Shares by the Shareholders, the Escrow Agent shall not vote any of the
Escrow Shares.

                 (d) TRANSFERABILITY; SALE. The interest of the Shareholders in
the Escrow Shares shall not be assignable or transferable so long as such Escrow
Shares are held by the Escrow Agent hereunder; PROVIDED, HOWEVER, that the
Escrow Agent may sell, transfer, or otherwise dispose of the Escrow Shares
pursuant to Sections 5 and 6 hereof, and as otherwise provided in this
Agreement.

            5.   RELEASE OF ESCROW SHARES.

                 (a) At any time, and from time to time, prior to twelve (12)
months after the Effective Date (the "TERMINATION DATE"), LP may make claims, in
the manner set forth in Section 6 hereof, for payment against the Escrow Shares
if it (or any other Indemnified Person) has paid or incurred Damages and is
entitled to indemnification under Article VIII of the Stock Purchase Agreement.
The Shareholders' Agent, on behalf of each of the Shareholders, agrees that the
Shareholders shall indemnify and hold harmless any Indemnified Person for such
Damages pursuant to Section VIII of the Stock Purchase Agreement. Any of the
Escrow Shares to be released pursuant to this Section 5(a) shall be valued in
accordance with the terms of this Agreement.

                 (b) As soon as possible after the Termination Date, upon
delivery of a notice executed jointly by both an LP Agent and the Shareholders'
Agent to the Escrow Agent (which notice shall not be withheld unless pursuant to
the matters provided for in Section 5(c) below), the Escrow Agent shall deliver
and/or submit for transfer, delivery and assignment to an Israeli trustee to be
designated in writing by the Shareholders' Agent within thirty days of the date
hereof (the "Israeli Trustee"), for the benefit of each of the Shareholders,
such Shareholder's pro rata portion of the Escrow Shares not subject to
outstanding Claim Notices (as defined herein).

                 (c) Notwithstanding the foregoing, if on the Termination Date
an LP Agent has previously given any Claim Notices (as defined herein) that have
not then been resolved in accordance with Section 6 below, the Escrow Agent
shall retain in the Escrow Account an amount of Escrow Shares having a Fair
Market Value (as defined in Section 7 hereof) equal to the aggregate Claimed
Amount (as defined herein) covered by all such Claim Notices that have not then
been resolved. Any Escrow Shares retained in escrow pursuant to this Section
5(c) shall be disbursed in accordance with the terms of the resolution of any
claims relating to any of the Escrow Shares retained hereunder.

            6.   ADMINISTRATION OF ESCROW ACCOUNT FOR INDEMNIFICATION CLAIMS.
With respect to indemnification claims, the Escrow Agent shall administer the
Escrow Account as follows:

                 (a) The release of Escrow Shares shall be applied to each
Shareholder in the proportion that the Escrow Shares of such Shareholder bears
to the sum of Escrow Shares then remaining in the Escrow. In lieu of releasing
any fractional Escrow Shares, any fraction of a released Escrow Share


                                       2
<PAGE>

that would otherwise be released shall be rounded to the nearest whole share of
Parent Common Stock (with one-half of a share being rounded upward).

                 (b) If an Indemnified Person has incurred or suffered Damages
for which it is entitled to indemnification by the Shareholders under the Stock
Purchase Agreement, the LP Agent shall, prior to the Termination Date, give
written notice of such claim (a "CLAIM NOTICE") to the Shareholders' Agent with
a copy to the Escrow Agent. Each Claim Notice shall state the amount of Damages
claimed (the "CLAIMED AMOUNT") and the basis for such claim.

                 (c) Claims for indemnification involving a claim or legal
proceeding by a third party shall be made in accordance with the procedures set
forth in the Stock Purchase Agreement and the provisions of this Section 6. For
indemnification claims not involving any claim or legal proceeding by a third
party, the procedures herein alone shall apply. Within twenty (20) business days
of receipt by the Shareholders' Agent of a Claim Notice, the Shareholders' Agent
shall provide to the party providing the Claim Notice (with a copy to the Escrow
Agent) a written response (the "RESPONSE NOTICE") in which the Shareholders'
Agent shall either: (i) agree that Escrow Shares having a Fair Market Value (as
computed pursuant to Section 7 below) equal to the full Claimed Amount may be
released from the Escrow Account to the Indemnified Person, (ii) agree that
Escrow Shares having a Fair Market Value equal to part, but not all, of the
Claimed Amount may be released from the Escrow Account to the Indemnified
Person, or (iii) contest that any of the Escrow Shares may be released from the
Escrow Account to the Indemnified Person. The Shareholders' Agent may contest
the release of Escrow Shares having a Fair Market Value equal to all or a
portion of the Claimed Amount only if the Shareholders' Agent has a good faith
belief that all or such portion of the Claimed Amount does not constitute
Damages for which the Indemnified Person is entitled to indemnification under
the Stock Purchase Agreement. If no Response Notice is delivered to, and
received by the Escrow Agent prior to twenty (20) business days of receipt of
the Claim Notice by the Shareholders' Agent, the Shareholders' Agent shall be
deemed to have agreed that Escrow Shares having a Fair Market Value equal to all
of the Claimed Amount may be released to the Indemnified Person from the Escrow
Account. Notwithstanding any terms of this Agreement to the contrary, no Claim
Notice or Response Notice shall be deemed to have been delivered to the Escrow
Agent until it is actually received by the Escrow Agent at the address set forth
in Section 12 hereof.

                 (d) If the Shareholders' Agent agrees (or is deemed to have
agreed) that Escrow Shares having a Fair Market Value equal to all of the
Claimed Amount may be released from the Escrow Account to the Indemnified
Person, the Escrow Agent shall promptly thereafter transfer, deliver and assign
to the Indemnified Person the Escrow Shares having a Fair Market Value equal to
the Claimed Amount (or such lesser amount of Escrow Shares as are then held in
the Escrow Account).

                 (e) If the Shareholders' Agent agrees that Escrow Shares having
a Fair Market Value equal to part, but not all, of the Claimed Amount (the
"PARTIAL AGREED AMOUNTS") may be released from the Escrow Account to the
Indemnified Person, the Escrow Agent promptly shall transfer, deliver and assign
to the Indemnified Person Escrow Shares having a Fair Market Value equal to the
sum of all Partial Agreed Amounts (or such lesser amount of Escrow Shares as are
then held in the Escrow Account).

                 (f) If the Shareholders' Agent contests the release of Escrow
Shares having a Fair Market Value equal to all or part of the Claimed Amount
(the "CONTESTED AMOUNT"), the Shareholders' Agent and the Indemnified Person or
LP Agent, as applicable, shall attempt promptly and in good faith to agree upon
the rights of the parties with respect to the Contested Amount. If the parties
should so agree, a memorandum setting forth such agreement shall be prepared and
signed by both parties and delivered to the Escrow Agent and, if such agreement
provides that all or a portion of the Contested


                                       3
<PAGE>

Amount is to be paid to the LP Agent, the Escrow Agent shall promptly transfer,
assign and deliver to the Indemnified Person from the Escrow Account an amount
of Escrow Shares having a Fair Market Value equal to the amount so agreed. If no
such agreement can be reached within 15 days, the matter shall be settled by
binding arbitration in New York City, New York. Notwithstanding the foregoing,
the parties may defer arbitration to a mutually agreeable later date. All claims
shall be settled by a single arbitrator mutually agreeable to the LP Agent and
the Shareholders' Agent, or if they cannot agree on a single arbitrator in 20
days, by three arbitrators, in accordance with the Commercial Arbitration Rules
then in effect of the American Arbitration Association (the "AAA RULES"). One of
such arbitrators shall be chosen by the LP Agent, one shall be chosen by the
Shareholders' Agent and the third shall be chosen by the first two arbitrators
selected pursuant to this sentence. The Party against whom a judgment is made or
against whom an award is entered shall pay the costs of arbitration and the
other Party's reasonable out of pocket costs and expenses, including without
limitation, reasonable attorney's fees. The arbitrator's decision shall relate
solely to whether the Indemnified Person is entitled to receive the Contested
Amount (or a portion thereof) pursuant to the applicable terms of the Stock
Purchase Agreement and this Agreement. The final decision of the arbitrator, or
a majority of the arbitrators in the case of three arbitrators, shall be
furnished to the Shareholders' Agent and the LP Agent in writing and shall
constitute a conclusive determination of the issue in question, binding upon the
Shareholders and LP, and shall not be contested by any of them. Such decision
may be used in a court of law only for the purpose of seeking enforcement of the
arbitrator's award. Either the Shareholders' Agent or an LP Agent may deliver a
memorandum to the Escrow Agent setting forth such arbitrator's decision in
accordance with the second sentence of this paragraph. The parties hereto agree
that all arbitration proceedings conducted pursuant to this Agreement shall be
held confidential.

                 (g) After delivery of a Response Notice that the Claimed Amount
is contested by the Shareholders' Agent, the Escrow Agent shall continue to hold
in the Escrow Account an amount of Escrow Shares having a Fair Market Value
sufficient to cover the Contested Amount (up to the amount of Escrow Shares then
available in the Escrow Account), notwithstanding the occurrence of the
Termination Date, until (i) delivery of a copy of a settlement agreement
executed by an LP Agent and the Shareholders' Agent setting forth instructions
to the Escrow Agent as to the release of Escrow Shares that shall be made with
respect to the Contested Amount or (ii) delivery of a copy of the final award of
the arbitrator, or a majority of the arbitrators in the case of three
arbitrators, and the memo referenced in the last sentence of the preceding
paragraph setting forth instructions to the Escrow Agent as to the release of
Escrow Shares that shall be made with respect to the Contested Amount. The
Escrow Agent shall thereupon release Escrow Shares from the Escrow Account (up
to the amount of Escrow Shares then available in the Escrow Account) in
accordance with such agreement or instructions.

            7.   VALUATION OF ESCROW SHARES. For purposes of this Agreement, the
Fair Market Value of each of the Escrow Shares shall be seven dollars ($7.00)
per share, with appropriate adjustment to take into account any stock split,
reverse stock split, stock dividend, recapitalization or other similar capital
adjustments with respect to LP's common stock. The Fair Market Value shall be
calculated as set forth above jointly by the LP Agent and the Shareholders'
Agent, and the results of such calculation shall be provided to the Escrow
Agent.

            8.   FEES AND EXPENSES OF THE ESCROW AGENT. LP hereby agrees to pay
the Escrow Agent's reasonable fees and expenses, including attorneys fees,
travel expenses, postal and delivery charges, and all other out-of-pocket
expenses incurred, in accepting and performing its appointment as Escrow Agent
hereunder (collectively, the "ESCROW AGENT EXPENSES").

            9.   GENERAL TERMS AND STANDARDS REGARDING THE ESCROW AGENT.
Notwithstanding any terms of this Agreement to the contrary, each term of this
Agreement, including without limitation


                                       4
<PAGE>

each of the stated duties and responsibilities of the Escrow Agent set forth
herein, shall be subject to the following terms and conditions:

                 (a) The duties, responsibilities and obligations of the Escrow
Agent shall be limited to those expressly set forth in this Agreement (and the
duty to exercise reasonable care in the physical safekeeping of any property
held in escrow hereunder), and no implied duties, responsibilities or
obligations shall be read into this Agreement against the Escrow Agent. Without
limiting the generality of the foregoing, the Escrow Agent shall have no duty to
take action to preserve or exercise rights in any property held by it hereunder
(including, without limitation, against prior parties or otherwise).

                 (b) The Escrow Agent shall not be subject to, bound by, charged
with notice of or be required to comply with or interpret any agreement or
document (including without limitation the Stock Purchase Agreement) between or
among the interested parties (whether or not reference to any such other
agreement or documents is expressed herein) other than this Agreement.

                 (c) The Escrow Agent shall in no instance be under any duty to
give any property held by it hereunder any greater degree of care than it gives
its own similar property. The Escrow Agent shall not be required to invest any
funds held hereunder, and shall not be obligated to pay interest on uninvested
funds. All amounts received by the Escrow Agent (and any credits to the Escrow
Account) shall be conditional upon collection (and actual receipt by the Escrow
Agent of final payment). In no event shall the Escrow Agent have any obligation
to advance funds.

                 (d) The Escrow Agent may rely upon, and shall be protected in
acting or refraining from acting upon, any written notice, instruction,
statement, request, waiver, order, judgement, certification, consent, receipt or
other paper or document furnished to it (not only as to genuineness, but also as
to its due execution and validity, the genuineness of signatures appearing
thereon and as to the truth and accuracy of any information therein contained),
which it in good faith believes to be genuine and signed or presented by the
proper person.

                 (e) Neither the Escrow Agent nor any of its directors, officers
or employees shall be liable to anyone for any error of judgment, or for any act
done or step taken or omitted to be taken by it or any of its directors,
officers or employees, or for any mistake of fact or law, or for anything which
it, or any of its directors, officers or employees, may do or refrain from doing
in connection with or in the administration of this Agreement, unless and except
to the extent the same constitutes gross negligence, bad faith or willful
misconduct on the part of the Escrow Agent. In no event shall the Escrow Agent
be liable for any indirect, punitive, special or consequential damages, or any
amount in excess of the value of the Escrow Shares (as of the date of the action
or omission giving rise to liability).

                 (f) The Escrow Agent shall not be deemed to have notice of any
fact, claim or demand with respect hereto unless actually known by an officer
charged with responsibility for administering this Agreement or unless in
writing received by the Escrow Agent and making specific reference to this
Agreement.

                 (g) No provision of this Agreement shall require the Escrow
Agent to expend or risk its own funds, or to take any legal or other action
hereunder which might in its judgement involve it in, or require it to incur in
connection with the performance of its duties hereunder, any expense or any
financial liability unless it shall be furnished with indemnification acceptable
to it.

                 (h) Any permissive right of the Escrow Agent to take any action
hereunder shall not be construed as duty.


                                       5
<PAGE>

                 (i) All indemnifications contained in this Agreement shall
survive the resignation or removal of the Escrow Agent, and shall survive the
termination of this Agreement.

                 (j) The Escrow Agent is not responsible for the recitals
appearing in this Agreement. The recitals shall be deemed to be statements of
the interested parties to this Agreement.

                 (k) The Escrow Agent has no responsibility for the sufficiency
of this Agreement for any purpose. Without limiting the foregoing, if any
security interest is referred to herein, the Escrow Agent shall have no
responsibility for, and makes no representation or warranty as to, the creation,
attachment or perfection of any such security interest or the sufficiency of
this Agreement therefor.

                 (l) Nothing in this Agreement shall obligate the Escrow Agent
to qualify to do business or act in any jurisdiction in which it is not
presently qualified to do business, or be deemed to impose upon the Escrow Agent
the duties of a trustee. The duties of the Escrow Agent under this Agreement are
strictly ministerial in nature.

                 (m) In no event shall the Escrow Agent have any liability for
any failure or inability of any of the interested parties to perform or observe
his or its duties under the Agreement, or by reason of a breach of this
Agreement by either of the interested parties. In no event shall the Escrow
Agent be obligated to take any action against any of the interested parties to
compel performance hereunder.

                 (n) The Escrow Agent shall in no instance be obligated to
commence, prosecute or defend any legal proceedings in connection herewith. The
Escrow Agent shall be authorized and entitled, however, in any instance to
commence, prosecute or defend any legal proceedings in connection herewith,
including without limitation any proceeding it may deem necessary to resolve any
matter or dispute, to obtain a necessary declaration of rights, or to appoint a
successor upon resignation (and after failure by the interested parties to
appoint a successor, as provided in Section 13).

                 (o) Whenever the terms hereof call for any notice, payment or
other action on a day which is not a business day, such payment or action may be
taken, or such notice given, as the case may be, on the next succeeding business
day. As used herein, "business day" shall mean any day other than a Saturday or
Sunday, or any other day on which the Escrow Agent is closed for business.

                 (p) In the event of any ambiguity or uncertainty under this
Agreement, or in any notice, instruction, or other communication received by the
Escrow Agent hereunder, the Escrow Agent may, in its reasonable discretion,
refrain from taking action, and may retain the Escrow Shares, until and unless
it receives written instruction signed by all interested parties, or a decision
by a court of competent jurisdiction which eliminates such uncertainty or
ambiguity.

                 (q) If at any time Escrow Agent is served with any judicial or
administrative order, judgement, decree, writ or other form of judicial
administrative process which in any way relates to or affects the Escrow Shares
(including but not limited to orders of attachment or garnishment or other forms
of levies or injunctions or stays relating to the Escrow Shares), Escrow Agent
is authorized to comply therewith in any manner as it or its legal counsel
reasonably deems appropriate; and if the Escrow Agent complies with any such
judicial or administrative order, judgement, decree, writ or other form of
judicial or administrative process, Escrow Agent shall not be liable to any of
the Parties hereto or to any other person or entity notwithstanding that though
such order, judgement, decree, writ or process may be subsequently modified,
annulled, set aside, vacated, found to have been without proper jurisdiction, or
otherwise determined to have been without legal force or effect.

                 (r) The Escrow Agent shall have no liability for the actions or
omissions of any transfer agent, book-entry depository, nominee, correspondent,
subagent or subcustodian, except to the extent that such action or omission of
any transfer agent, book-entry depository, nominee, correspondent, subagent or
subcustodian was caused by the Escrow Agent's own gross negligence, bad faith or
willful misconduct.

                 (s) The parties understand that the Escrow Shares are not
subject to an effective registration statement at the time of this Agreement,
and that the Escrow Agent shall not be responsible for fluctuations in the
market in connection with any transfer of the shares.

connection with this Agreement or the administration of this Agreement or the
performance or observance by the Escrow Agent of its responsibilities or
services under this Agreement (including but not limited to reasonable attorneys
fees and other costs and expenses of defending or preparing to defend against
any claim or liability), unless and except to the extent such loss, liability,
damage, cost or expense shall be caused by the Escrow Agent's own willful
misconduct, bad faith or gross negligence; provided, that any indemnification
payment required to be made to the Escrow Agent by the Shareholders should be
made from, and as a charge against, the Escrow Account.

                 (b) TAX-RELATED MATTERS. Each of the Shareholders (jointly and

the payment of Escrow Shares under this Agreement, and, without limiting the
generality of Section 10(a) above, hereby agree to indemnify and hold the Escrow
Agent harmless from and against any taxes, additions for late payment, interest,
penalties and other expenses, that may be assessed against the Escrow Agent on
any such payment or other activities under this Agreement. LP and each of the
Shareholders undertake to instruct the Escrow Agent in writing with respect to
the Escrow Agent's responsibility for withholding and other taxes, assessments
or other governmental charges, certifications and governmental reporting in
connection with its acting as Escrow Agent under this Agreement. Each of the
Shareholders (severally as a group) and LP, jointly and severally, agree to
indemnify and hold the Escrow Agent harmless from any liability on account of
taxes, assessments or other governmental charges, including without limitation
the withholding or deduction of or the failure to withhold or deduct same, and

Account in accordance with this Agreement, provided that the provisions of
Sections 9 and 10 above shall survive such termination.

                              EMPLOYMENT AGREEMENT


      This Employment Agreement (the "Agreement"), is made and entered into this
12th day of October, 2000, by and between HumanClick Ltd. a private company
organized under the laws of the State of Israel, with principal offices located
at 33 Bnei Zion, Israel 60910 (the "Company"), and Eitan Ron (the "Executive").

                                   WITNESSETH

      WHEREAS, LivePerson, Inc., (hereinafter "LivePerson") is acquiring all of
the shares of the Company pursuant to a certain Stock Purchase Agreement dated
October 12th, 2000, (referred to herein as the "Acquisition"); and

      WHEREAS, the Executive served as Chief Executive Officer of the Company
prior to the Acquisition; and

      WHEREAS, the Executive's continuing personal services are critical to
maintaining the value of the shares being acquired by the Company in the
Acquisition; and,

      WHEREAS, the Executive and the Company desire to enter into a formal
Employment Agreement to fully recognize the contributions of Executive to the
Company and to assure continuous harmonious performance of the affairs of the
Company.

      NOW, THEREFORE, in consideration of the mutual promises, terms,
provisions, and conditions contained herein, the parties agree as follows:

1.    POSITION.

      The Company hereby agrees to employ the Executive to serve in the role of
General Manager of the Company, subject to the limitations set forth herein. The
Executive accepts such employment upon the terms and conditions set forth
herein, and further agrees to perform to the best of his abilities the duties
generally associated with his position, as well as such other duties
commensurate with his position as General Manager as may be reasonably assigned
by the Board of Directors of the Company (the "Board"). The Executive shall, at
all times during the Term, report directly to the Board. The Executive shall
perform his duties diligently and faithfully and shall devote his full business
time and attention to such duties.

2.    TERM OF EMPLOYMENT AND RENEWAL.

      The term of Executive's employment under this Agreement will commence on
the date of this Agreement (the "Effective Date"). Subject to the provisions of
Section 8 of this Agreement, the term of Executive's employment hereunder shall
be for a term of three (3) years from the Effective Date (the "Term").


<PAGE>

3.    COMPENSATION AND BENEFITS.

      (a)   SALARY. Commencing on the Effective Date, the Company agrees to pay
the Executive a base salary at an annual rate of One Hundred Ten Thousand
Dollars ($110,000) for the first year of the Term, payable in such installments
as is the policy of the Company (the "Salary"), but no less frequently than
monthly. Thereafter, the Company will review the Executive's Salary on an annual
basis, and, at its discretion, may increase the Executive's Salary but in no
event diminish the amount of Executive's Salary below the initial rate, or below
the increased rates unless all of the Executive's peer executives undergo
substantially equivalent decreases.

            The Executive acknowledges and agrees that his position with the
Company is one that requires a special measure of personal trust as defined in
the Work and Rest Hours Law, 5711-1951, and, therefore, the provisions of such
law shall not apply to the Executive and the Executive shall not be entitled to
compensation for working more than forty-five (45) hours per week, beyond the
compensation set forth in this Section 3.

      (b)   BONUS. The Executive shall be eligible to receive annual bonuses at
the discretion of the Chief Executive Officer and Compensation Committee of the
Board according to performance goals appropriate for the Executive's position
and role to be issued by the Company.

      (c)   BENEFITS. The Executive shall be entitled to participate in all
employee benefit plans applicable for the Executive's level which the Company
provides or may establish from time to time for the benefit of its employees,
including, without limitation, group life, medical, surgical, dental and other
health insurance, short and long-term disability, deferred compensation,
profit-sharing and similar plans. The Company will pay on the Executive's behalf
at the Company's sole cost and expense a sum equal to 13 1/3% (thirteen and
one-third percent) of the Executive's Salary each month for executives'
insurance. The Executive will contribute a sum equal to 5% (five percent) of his
monthly Salary for each month for the insurance for the provident fund in
accordance with custom and practice. All payments provided for in this Section
will be made in such amounts and in such timely fashion as to guarantee the
Executive the full rights and benefits of such insurance at all times during the
Term and thereafter in accordance with law and practice. Ownership of all
accounts and insurance policies provided for in this Section shall be in the
name of the Executive and on termination of this Agreement will be released to
the Executive to be applied towards any obligation of the Company to make
severance payments to the Executive. The Company will pay, at its sole cost and
expense, a sum equal to 7 1/2% (seven and one-half percent) of the Executive's
monthly Salary on behalf of the Executive to an Advanced Study Fund in which the
Company participates. The Executive will pay a sum equal to 2 1/2% (two and
one-half percent) of his monthly Salary, at his expense, into said fund, as is
standard practice. All amounts paid to the Advanced Study Fund under this
Section will not exceed the amounts exempt from tax under the income tax
regulations applicable to payments to Advanced Study Funds. During the Term, the
Company shall extend to the Executive's use a leased car as shall be reasonably
elected by the Executive and shall bear all expenses associated with the use of
the car. The Company shall


                                       2
<PAGE>

gross-up any tax applicable on the use of the car by the Executive according to
the then applicable law. The Executive shall be entitled to annual Recreation
Pay per year according to the then prevailing applicable law or custom at the
minimum amount required by law. The Executive shall also be entitled to fifteen
(15) business days paid vacation per year. Annual vacations may be accumulated
and/or redeemed as provided under the law. The Executive shall be entitled to
Sick Leave according to the then prevailing applicable law. The Company may
purchase one or more "key man" insurance policies on the Executive's life, each
of which will be payable to and owned by the Company. The Company, in its sole
discretion, may select the amount and type of key man life insurance purchased,
and the Executive will have no interest in any such policy. The Executive will
cooperate with the Company in securing this key man insurance, by submitting to
all required medical examinations, supplying all information and executing all
documents required in order for the Company to secure the insurance.

      (d)   EXPENSES. The Company shall pay or reimburse the Executive for all
reasonable out-of-pocket expenses actually incurred by him during the Term in
performing services hereunder, provided that the Executive properly accounts for
such expenses in accordance with the Company's policies.

4.    NON-COMPETITION AND NON-SOLICITATION.

      The Executive acknowledges that the Company has invested substantial time,
money and resources in the development and retention of its Proprietary
Information (including trade secrets) as defined in the Company's Proprietary
Information and Intellectual Property Agreement referenced in Section 10 of this
Agreement, customers, accounts and business partners, and further acknowledges
that during the course of the Executive's employment with the Company the
Executive has had and will have access to the Company's Inventions and
Confidential Information (including trade secrets), and will be introduced to
existing and prospective customers, accounts and business partners of the
Company. The Executive acknowledges and agrees that any and all "goodwill"
associated with any existing or prospective customer, account or business
partner belongs exclusively to the Company, including, but not limited to, any
goodwill created as a result of direct or indirect contacts or relationships
between the Executive and any existing or prospective customers, accounts or
business partners. The Executive expressly acknowledges that the provisions of
this Section 4 are necessary to protect the investment by the Company in
HumanClick. Additionally, the parties acknowledge and agree that Executive
possesses skills that are special, unique or extraordinary and that the value of
the Company depends upon his use of such skills on its behalf.

      In recognition of this, the Executive covenants and agrees that:

      (a)   During the Term, and for a period of one (1) year after termination
of this Agreement, the Executive may not, without the prior written consent of
the Board, (whether as an employee, agent, servant, owner, partner, consultant,
independent contractor, representative, stockholder or in any other capacity
whatsoever) participate in any business that offers products or services
competitive in any way to those offered by the Company or that were under active
development or consideration by the Company during the Term.


                                       3
<PAGE>

      (b)   During the Term, and for a period of one (1) year after termination
of this Agreement, the Executive may not entice, solicit or encourage any
Company employee to leave the employ of the Company or any independent
contractor to sever its engagement with the Company, absent prior written
consent to do so from the Board.

      (c)   During the Term, and for a period of one (1) year after termination
of this Agreement, the Executive may not, directly or indirectly, entice,
solicit or encourage any customer or prospective customer of the Company to
cease doing business with the Company, reduce its relationship with the Company
or refrain from establishing or expanding a relationship with the Company.

5.    NON-DISPARAGEMENT.

      The Executive and the Company hereby agree that during the Term, and at
all times thereafter, the Executive will not make any statement that is
disparaging about the Company, any of its officers, directors, or shareholders,
including, but not limited to, any statement that disparages the products,
services, finances, financial condition, capabilities or other aspects of the
business of the Company and the Company shall not make such statements with
respect to the Executive, including, but not limited to, any statement that

6.    PROVISIONS NECESSARY AND REASONABLE.

      (a)   The Executive agrees that (i) the provisions of Sections 4 and 5 of
this Agreement are necessary and reasonable to protect the Company's
Confidential Information, Inventions, and goodwill; (ii) the specific temporal,
geographic and substantive provisions set forth in Section 4 of this Agreement
are reasonable and necessary to protect the Company's business interests; and

remedy at law for such breach. In recognition of the foregoing, the Executive

covenants, in addition to such other remedies as the Company may have at law,
without posting any bond or security, the Company shall be entitled to seek and
obtain equitable relief, in the form of specific performance, and/or temporary,
preliminary or permanent injunctive relief, or any other equitable remedy which
then may be available. The seeking of such injunction or order shall not affect
the Company's right to seek and obtain damages or other equitable relief on
account of any such actual or threatened breach.

      (b)   If any of the covenants contained in Sections 4 and 5 hereof, or any
part thereof, are hereafter construed to be invalid or unenforceable, the same
shall not affect the remainder of the covenant or covenants, which shall be
given full effect without regard to the invalid portions.

      (c)   If any of the covenants contained in Sections 4 and 5 hereof, or any
part thereof, are held to be unenforceable by a court of competent jurisdiction
because of the temporal or


                                       4
<PAGE>

geographic scope of such provision or the area covered thereby, the parties
agree that the court making such determination shall have the power to reduce
the duration and/or geographic area of such provision and, in its reduced form,
such provision shall be enforceable.

7.    REPRESENTATIONS REGARDING PRIOR WORK AND LEGAL OBLIGATIONS.

any function for, the Company.

such information for the benefit of the Company.

                              EMPLOYMENT AGREEMENT


      This Employment Agreement (the "Agreement"), is made and entered into this
12th day of October, 2000, by and between HumanClick Ltd. a private company
organized under the laws of the State of Israel, with principal offices located
at 33 Bnei Zion, Israel 60910 (the "Company"), and Tal Goldberg (the
"Executive").

                                   WITNESSETH

      WHEREAS, LivePerson, Inc., (hereinafter "LivePerson") is acquiring all of
the shares of the Company pursuant to a certain Stock Purchase Agreement dated
October 12, 2000, (referred to herein as the "Acquisition"); and

      WHEREAS, the Executive served as President of the Company prior to the
Acquisition; and

      WHEREAS, the Executive's continuing personal services are critical to
maintaining the value of the shares being acquired by the Company in the
Acquisition; and,

      WHEREAS, the Executive and the Company desire to enter into a formal
Employment Agreement to fully recognize the contributions of Executive to the
Company and to assure continuous harmonious performance of the affairs of the
Company.

      NOW, THEREFORE, in consideration of the mutual promises, terms,
provisions, and conditions contained herein, the parties agree as follows:

1.    POSITION.

      The Company hereby agrees to employ the Executive to serve in the role of
Executive Vice President of Technology of the Company, subject to the
limitations set forth herein. The Executive accepts such employment upon the
terms and conditions set forth herein, and further agrees to perform to the best
of his abilities the duties generally associated with his position, as well as
such other duties commensurate with his position as Executive Vice President of
Technology as may be reasonably assigned by the Board of Directors of the
Company (the "Board"). The Executive shall, at all times during the Term, report
directly to the Board. The Executive shall perform his duties diligently and
faithfully and shall devote his full business time and attention to such duties.

2.    TERM OF EMPLOYMENT AND RENEWAL.

      The term of Executive's employment under this Agreement will commence on
the date of this Agreement (the "Effective Date"). Subject to the provisions of
Section 8 of this Agreement,


<PAGE>

the term of Executive's employment hereunder shall be for a term of three (3)
years from the Effective Date (the "Term").

3.    COMPENSATION AND BENEFITS.

      (a)   SALARY. Commencing on the Effective Date, the Company agrees to pay
the Executive a base salary at an annual rate of One Hundred Ten Thousand
Dollars ($110,000) for the first year of the Term, payable in such installments
as is the policy of the Company (the "Salary"), but no less frequently than
monthly. Thereafter, the Company will review the Executive's Salary on an annual
basis, and, at its discretion, may increase the Executive's Salary but in no
event diminish the amount of Executive's Salary below the initial rate, or below
the increased rates unless all of the Executive's peer executives undergo
substantially equivalent decreases.

            The Executive acknowledges and agrees that his position with the
Company is one that requires a special measure of personal trust as defined in
the Work and Rest Hours Law, 5711-1951, and, therefore, the provisions of such
law shall not apply to the Executive and the Executive shall not be entitled to
compensation for working more than forty-five (45) hours per week, beyond the
compensation set forth in this Section 3.

      (b)   BONUS. The Executive shall be eligible to receive annual bonuses at
the discretion of the Chief Executive Officer and Compensation Committee of the
Board according to performance goals appropriate for the Executive's position
and role to be issued by the Company.

      (c)   BENEFITS. The Executive shall be entitled to participate in all
employee benefit plans applicable for the Executive's level which the Company
provides or may establish from time to time for the benefit of its employees,
including, without limitation, group life, medical, surgical, dental and other
health insurance, short and long-term disability, deferred compensation,
profit-sharing and similar plans. The Company will pay on the Executive's behalf
at the Company's sole cost and expense a sum equal to 13 1/3% (thirteen and
one-third percent) of the Executive's Salary each month for executives'
insurance. The Executive will contribute a sum equal to 5% (five percent) of his
monthly Salary for each month for the insurance for the provident fund in
accordance with custom and practice. All payments provided for in this Section
will be made in such amounts and in such timely fashion as to guarantee the
Executive the full rights and benefits of such insurance at all times during the
Term and thereafter in accordance with law and practice. Ownership of all
accounts and insurance policies provided for in this Section shall be in the
name of the Executive and on termination of this Agreement will be released to
the Executive to be applied towards any obligation of the Company to make
severance payments to the Executive. The Company will pay, at its sole cost and
expense, a sum equal to 7 1/2% (seven and one-half percent) of the Executive's
monthly Salary on behalf of the Executive to an Advanced Study Fund in which the
Company participates. The Executive will pay a sum equal to 2 1/2% (two and
one-half percent) of his monthly Salary, at his expense, into said fund, as is
standard practice. All amounts paid to the Advanced Study Fund under this
Section will not exceed the amounts exempt from tax under the income tax
regulations applicable to payments to Advanced Study Funds. During the Term, the


                                       2
<PAGE>

Company shall extend to the Executive's use a leased car as shall be reasonably
elected by the Executive and shall bear all expenses associated with the use of
the car. The Company shall gross-up any tax applicable on the use of the car by
the Executive according to the then applicable law. The Executive shall be
entitled to annual Recreation Pay per year according to the then prevailing
applicable law or custom at the minimum amount required by law. The Executive
shall also be entitled to fifteen (15) business days paid vacation per year.
Annual vacations may be accumulated and/or redeemed as provided under the law.
The Executive shall be entitled to Sick Leave according to the then prevailing
applicable law. The Company may purchase one or more "key man" insurance
policies on the Executive's life, each of which will be payable to and owned by
the Company. The Company, in its sole discretion, may select the amount and type
of key man life insurance purchased, and the Executive will have no interest in
any such policy. The Executive will cooperate with the Company in securing this
key man insurance, by submitting to all required medical examinations, supplying
all information and executing all documents required in order for the Company to
secure the insurance.

      (d)   EXPENSES. The Company shall pay or reimburse the Executive for all
reasonable out-of-pocket expenses actually incurred by him during the Term in
performing services hereunder, provided that the Executive properly accounts for
such expenses in accordance with the Company's policies.

4.    NON-COMPETITION AND NON-SOLICITATION.

      The Executive acknowledges that the Company has invested substantial time,
money and resources in the development and retention of its Proprietary
Information (including trade secrets) as defined in the Company's Proprietary
Information and Intellectual Property Agreement referenced in Section 10 of this
Agreement, customers, accounts and business partners, and further acknowledges
that during the course of the Executive's employment with the Company the
Executive has had and will have access to the Company's Inventions and
Confidential Information (including trade secrets), and will be introduced to
existing and prospective customers, accounts and business partners of the
Company. The Executive acknowledges and agrees that any and all "goodwill"
associated with any existing or prospective customer, account or business
partner belongs exclusively to the Company, including, but not limited to, any
goodwill created as a result of direct or indirect contacts or relationships
between the Executive and any existing or prospective customers, accounts or
business partners. The Executive expressly acknowledges that the provisions of
this Section 4 are necessary to protect the investment by the Company in
HumanClick. Additionally, the parties acknowledge and agree that Executive
possesses skills that are special, unique or extraordinary and that the value of
the Company depends upon his use of such skills on its behalf.

      In recognition of this, the Executive covenants and agrees that:

      (a)   During the Term, and for a period of one (1) year after termination
of this Agreement, the Executive may not, without the prior written consent of
the Board, (whether as an employee, agent, servant, owner, partner, consultant,
independent contractor, representative, stockholder or in any other capacity
whatsoever) participate in any business that offers products


                                       3
<PAGE>

or services competitive in any way to those offered by the Company or that were
under active development or consideration by the Company during the Term.

      (b)   During the Term, and for a period of one (1) year after termination
of this Agreement, the Executive may not entice, solicit or encourage any
Company employee to leave the employ of the Company or any independent
contractor to sever its engagement with the Company, absent prior written
consent to do so from the Board.

      (c)   During the Term, and for a period of one (1) year after termination
of this Agreement, the Executive may not, directly or indirectly, entice,
solicit or encourage any customer or prospective customer of the Company to

or refrain from establishing or expanding a relationship with the Company.

5.    NON-DISPARAGEMENT.

      The Executive and the Company hereby agree that during the Term, and at
all times thereafter, the Executive will not make any statement that is
disparaging about the Company, any of its officers, directors, or shareholders,
including, but not limited to, any statement that disparages the products,
services, finances, financial condition, capabilities or other aspects of the
business of the Company and the Company shall not make such statements with
respect to the Executive, including, but not limited to, any statement that
disparages his ability, services, morality standards or other aspects of his
employment. The Executive further agrees that during the same period the
Executive will not engage in any conduct that is intended to inflict harm upon
the professional or personal reputation of the Company or any of its officers,
directors, shareholders or employees.

6.    PROVISIONS NECESSARY AND REASONABLE.

      (a)   The Executive agrees that (i) the provisions of Sections 4 and 5 of
this Agreement are necessary and reasonable to protect the Company's
Confidential Information, Inventions, and goodwill; (ii) the specific temporal,
geographic and substantive provisions set forth in Section 4 of this Agreement
are reasonable and necessary to protect the Company's business interests; and
(iii) in the event of any breach of any of the covenants set forth herein, the
Company would suffer substantial irreparable harm and would not have an adequate
remedy at law for such breach. In recognition of the foregoing, the Executive
agrees that in the event of a breach or threatened breach of any of these
covenants, in addition to such other remedies as the Company may have at law,
without posting any bond or security, the Company shall be entitled to seek and
obtain equitable relief, in the form of specific performance, and/or temporary,
preliminary or permanent injunctive relief, or any other equitable remedy which
then may be available. The seeking of such injunction or order shall not affect
the Company's right to seek and obtain damages or other equitable relief on
account of any such actual or threatened breach.

      (b)   If any of the covenants contained in Sections 4 and 5 hereof, or any
part thereof, are hereafter construed to be invalid or unenforceable, the same
shall not affect the remainder of the covenant or covenants, which shall be
given full effect without regard to the invalid portions.


                                       4
<PAGE>

      (c)   If any of the covenants contained in Sections 4 and 5 hereof, or any
part thereof, are held to be unenforceable by a court of competent jurisdiction
because of the temporal or geographic scope of such provision or the area
covered thereby, the parties agree that the court making such determination
shall have the power to reduce the duration and/or geographic area of such
provision and, in its reduced form, such provision shall be enforceable.

7.    REPRESENTATIONS REGARDING PRIOR WORK AND LEGAL OBLIGATIONS.

      (a)   The Executive represents that the Executive has no agreement or
other legal obligation with any prior employer, or any other person or entity,
that restricts the Executive's ability to accept employment with, or to perform
any function for, the Company.

      (b)   The Executive has been advised by the Company that at no time should
the Executive divulge to or use for the benefit of the Company any trade secret
or confidential or proprietary information of any previous employer. The
Executive expressly acknowledges that the Executive has not divulged or used any
such information for the benefit of the Company.

      (c)   The Executive acknowledges that the Executive has not and will not
misappropriate any Invention that the Executive played any part in creating

      (b)   TERMINATION BY THE COMPANY WITHOUT CAUSE. The Executive's employment
hereunder may be terminated without Cause by the Company upon written notice to

under the same conditions as exist at the time of termination, for a six (6)

      Re:   HUMANCLICK LTD.

Ladies and Gentlemen:

We have acted as Israeli counsel to HumanClick Ltd., an Israeli corporation (the
"Company"), in connection with the sale of all of the outstanding capital stock
of the Company, pursuant to the Stock Purchase Agreement dated as of October 12,
2000 between LivePerson, Inc., a Delaware corporation (the "Purchaser"), the
Company and the shareholders of the Company named in SCHEDULE I thereto (the
"Shareholders") (such agreement, the "Purchase Agreement"). This opinion is
being rendered to you pursuant to Section 7.02(e) of the Purchase Agreement.
Capitalized terms used herein and not otherwise defined shall have the same
meaning given to such terms in the Purchase Agreement.

      In so acting, and as a basis for the opinions herein set forth, we have
examined original, photocopied, facsimile copies or electronically transmitted
versions of only the Purchase Agreement, including all schedules and exhibits
thereto, and the other Transaction Documents, the currently in effect Memorandum
and Articles of Association of the Company, certified corporate resolutions and
shareholders register provided to us by the Company and certificates of public
officials which we have deemed relevant for the purpose of this opinion (the
"Documents"). We have assumed the due authorization, execution and delivery of
each of the Purchase Agreement and the other Transaction Documents by all
parties thereto (other than the Company) and that each such agreement
constitutes the legal, valid and binding obligation of each such party,
enforceable against it in accordance with its terms. We have further assumed,
without investigation, the legal capacity of natural persons, actual compliance
of all parties with their covenants and agreements and with all relevant laws,
the genuineness of all signatures, the authenticity of all documents submitted
to us as originals, the conformity to original documents of all documents
submitted, facsimile or electronically transmitted to us as copies and that such
documents as examined by us are true, complete and correct, are in full force
and effect and have not been amended, rescinded, supplemented or otherwise
modified. As to various questions of fact relevant to the opinions expressed
herein, we have relied exclusively upon and assumed the completeness and
accuracy of, without any independent investigation or


<PAGE>

verification, the Documents and the representations, warranties and other
statements of fact by the parties thereto as contained therein, assuming,
without verification, that such are accurate and complete and that there are no
other records or facts that may be relevant to our opinions except as set forth
therein. With your permission, all other assumptions and statements of reliance
as indicated herein have been made without any independent investigation or
verification on our part except to the extent otherwise expressly stated in this
opinion, and we express no opinion with respect to the subject matter or
accuracy of such assumptions or items relied upon.

      Our opinions are limited to Israeli Laws and regulations. With regard to
the opinions expressed in Articles (3), (4) and (6) below, our opinions are
limited to a review of only those Israeli laws and regulations that, in our
experience, are normally applicable to transactions of the type contemplated by
the Purchase Agreement solely on the basis of the description of such matters in
the materials mentioned above. Our opinions specifically exclude any aspect of
intellectual property laws and private international law.

      We do not opine as to the laws of all jurisdictions other than the State
of Israel as the same are in force on the date hereof, such opinions being based
on current law, therefore there can be no assurance that the views expressed in
such opinions will be accepted by the relevant administrative or judicial
authorities. We assume no obligation to update this opinion or to advise you of
any events that occur subsequent to the date of this opinion.

      As used in this opinion, any use of the term "knowledge" or similar
language means that, after an examination of documents made available by the
Company to attorneys of this firm in the course of their handling the legal
affairs of the Company, but without any further independent factual
investigation, we find no reason to believe that the opinions expressed herein
are factually incorrect.

      For purposes of this opinion, we are assuming that each party to the
Purchase Agreement and the other Transaction Documents (other than the Company)
has all requisite power and authority and (where applicable) has taken any and
all necessary corporate or partnership action, to execute and deliver the
Purchase Agreement and the other Transaction Documents, and that each party has
entered into the Purchase Agreement and other Transaction Documents for value,
in good faith and without notice of any adverse fact.

      Based on and subject to the foregoing and the other reservations set forth
herein, we are of the opinion that:

1.    The Company is a corporation duly organized and validly existing under the
      laws of the State of Israel and, to our knowledge, is not the subject of
      any proceedings to strike the Company from the Registrar of Companies. The
      Company has the requisite corporate power and authority to own its
      properties and to conduct its business as, to our knowledge, it is
      presently conducted.

2.    The Company has the requisite corporate power and authority to execute,
      deliver and perform the Purchase Agreement and the other Transaction
      Documents to which it is a party. The Company has taken all necessary
      corporate action to approve and adopt the Purchase

<PAGE>

      Agreement and the other Transaction Documents to which the Company is a
      party and to approve and to authorize the performance of the transactions
      contemplated thereby. Each of the Purchase Agreement and the other
      Transaction Documents to which the Company is a party has been duly and
      validly authorized by the Company and has been duly executed and delivered
      by an authorized officer of the Company.

3.    Neither the execution or delivery by the Company of the Transaction
      Documents to which it is a party, nor the consummation by the Company at
      the Closing of the transactions contemplated thereby, will (i) violate any
      provision of the Memorandum of Association or the Articles of Association
      of the Company, (ii) violate or be in conflict with any Israeli laws which
      to our knowledge are applicable to the Company, or (iii) to our knowledge,
      violate or contravene any judgment, writ, decree, injunction or order of
      any Israeli court, or any arbitrator or governmental agency or authority,
      having jurisdiction over the Company or its properties or by which the
      Company may be bound.

4.    No consents, approvals or authorizations of or filings with any
      governmental authority of the State of Israel are required or necessary on
      the part of the Company in connection with the execution, delivery and
      performance at the Closing by the Company of the Transaction Documents,
      except for such consents, approvals, authorizations or filings which have
      been obtained, waived or made prior to the date hereof.

5.    We have no knowledge of any private or governmental action, suit, claim,
      arbitration pending before any agency, court or tribunal, foreign or
      domestic, against the Company or any of its properties or any of its
      officers or directors (in their capacities as such), and to our knowledge
      there is no judgment, decree or order against the Company or any of its
      properties or any of its officers or directors (in their capacities as
      such) that could prevent, enjoin or materially alter or delay any of the
      transactions contemplated by the Purchase Agreement or the other
      Transaction Documents nor are we aware of any litigation pending, or
      threatened in writing, against the Company by reason of the current
      activities of the Company or the past employment relationships of its
      officers, directors or employees.

6.    Based on our review of the minute books, register of members and other
      records of the Company, immediately prior to the consummation of the
      transactions contemplated by the Purchase Agreement the registered share
      capital of the Company consists of no preferred shares and of 3,800,000
      ordinary shares, par value NIS 0.01 per share (the "Ordinary Shares") of
      which 1,906,512 are issued and outstanding as of the date hereof, all of
      which have been validly issued and are fully paid and, based on the
      Company's Registrar of Members, are held of record by the Shareholders
      named in Schedule I to the Purchase Agreement.

      The opinions set forth herein are: (i) strictly confined to Israeli laws
as the same are in force on the date hereof and to Israeli matters, and no
opinion is expressed as to the effect or implication of any other law; (ii)
subject to any limitation that may be imposed by applicable bankruptcy,
insolvency, fraudulent conveyance, composition, reorganization, moratorium or
other similar laws affecting creditors' rights and remedies generally and by the
application by a

<PAGE>

court of equitable principles (regardless of whether enforcement is sought in a
proceedings in equity or at law); and (iii) are further qualified by any
limitations imposed by general principles of equity, good faith, fair dealing,
minority oppression, commercial reasonableness or upon the availability of
equitable remedies or the enforcement of provisions of any documents referred to
herein.

      This opinion is furnished to you solely for your benefit in connection
with the consummation of the Closing and is not to be used, circulated, quoted
or otherwise referred to for any other purpose without our express prior written
permission.




                                    Very truly yours,

We have acted as Special Israeli counsel to _________, all Israeli corporations
(the "Shareholders"), in connection with the sale of the outstanding capital
stock of HumanClick Ltd. (the "Company"), pursuant to the Stock Purchase

statements of reliance as indicated herein have been made without any
independent investigation or verification on our part except to the extent
otherwise expressly stated in this opinion, and we express no opinion with
respect to the subject matter or accuracy of such assumptions or items relied
upon.

      Our opinions are limited to Israeli Laws and regulations. With regard to
the opinions expressed in Articles (2) below, our opinions are limited to a
review of only those Israeli laws and regulations that, in our experience, are

      Based on and subject to the foregoing and the other reservations set forth

      1. Each Shareholder has full right, power and authority to enter into and
to perform its obligations under the Transaction Documents to which it is a
party; the execution and delivery of each such Transaction Document by each
Shareholder has been duly authorized by such Shareholder, and each such
Transaction Document has been duly executed by or on behalf of such
Shareholders.

<PAGE>

      2. To our knowledge, no consent, approval, authorization or order of or
qualification with any court, government or governmental agency in Israel is
necessary in connection with the consummation by the Shareholders of the
transactions contemplated in the Transaction Documents.

      3. To our knowledge without making independent investigation and based
solely on search of the computerized system of the Registrar of Companies, there
are no liens or encumbrances over the Company Shares to be sold by the
Shareholders under the Stock Purchase Agreement.

      The opinions set forth herein are: (i) strictly confined to Israeli laws

            RE:   STOCK PURCHASE AGREEMENT DATED AS OF OCTOBER 12, 2000

Ladies and Gentlemen:

            We have acted as U.S. counsel to HumanClick, Ltd., a private company
organized under the laws of the State of Israel (the "COMPANY"), in connection
with the purchase by LivePerson, Inc., a Delaware corporation (the "BUYER"), of
all of the outstanding capital stock of the Company pursuant to a certain Stock
Purchase Agreement dated as of October 12, 2000 between the Buyer, the Company
and the shareholders of the Company named in Schedule I thereto (the
"SHAREHOLDERS") (such agreement, the "PURCHASE AGREEMENT"). Capitalized terms
used herein and not otherwise defined herein shall have the same meanings herein
as are ascribed to such terms in the Purchase Agreement.

            This opinion letter is provided to you at the request of the Company
and the Shareholders in satisfaction of the condition set forth in Section
7.02(e) of the Purchase Agreement. In addition, we have examined originals or
copies of: (i) the Purchase Agreement; (ii) a certain Escrow Agreement dated as
of October 12, 2000 between the Buyer, the Company, First Union National Bank
(as Escrow Agent) and Eitan Ron (as Shareholders' Agent); (iii) a certain
Repurchase Option Agreement dated as of October 12, 2000 between the Buyer,
Eitan Ron and Tal Goldberg; and (iv) originals or copies of such corporate
resolutions of the Company as we have deemed necessary or appropriate as a basis
for the opinions hereinafter expressed. The documents listed as items (i)
through (iii) above are referred to herein as the "Transaction Documents".

            In connection with the opinions expressed herein, we have made such
examination of law as we deemed necessary. In our examination, we have assumed
the genuineness of all signatures, the legal capacity of all natural persons,
the authenticity of all documents submitted to us as originals, the conformity
to original documents of all documents submitted to us as certified, facsimile
or photostatic copies and the authenticity of the originals of such copies.

            In rendering the opinions set forth herein, we have also assumed:
(A) that the Transaction Documents have been duly and validly executed and
delivered by or on behalf of each party thereto other than the Company and the
Shareholders, that each party to the

<PAGE>

Transaction Documents other than the Company and the Shareholders has the power
to enter into and to perform its obligations thereunder and that the Transaction
Documents constitute legal, valid, binding and enforceable obligations of each
such party; and (B) that the representations and warranties made in the
Transaction Documents by the parties thereto other than the Company and the
Shareholders are true and correct.

            Whenever a statement herein is qualified by the expressions "known
to us," "to our knowledge," "we are not aware," or a similar phrase or
expression with respect to our knowledge of matters of fact, it is intended to
mean that our knowledge is based upon the records, documents, instruments and
certificates described above and the current actual knowledge of those attorneys
within this Firm who have given substantive attention to the transactions
contemplated by the Transaction Documents, or who are presently involved in
substantive legal representation of the Company (but not including any
constructive or imputed notice of any information) and that we have not
otherwise undertaken any independent investigations for the purpose of rendering
this opinion letter. Please be advised that the Company is also represented by
other attorneys and that we do not represent the Company with respect to all
matters.

            We express no opinion with respect to the Purchase Agreement or any
of the other Transaction Documents, or any right, power, privilege, remedy or
interest intended to be created thereunder, insofar as: (a) any of the rights,
powers, privileges, remedies and interests of a party thereunder may be limited
(i) by applicable bankruptcy, insolvency, fraudulent conveyance, reorganization
or other laws affecting any rights, powers, privileges, remedies and interests
of creditors generally, (ii) by rules or principles of equity affecting the
enforcement of obligations generally, whether at law, in equity or otherwise, or
(iii) by the exercise of the discretionary powers of any court or other
authority before which may be brought any proceeding seeking equitable or other
remedies, including, without limitation, specific performance, injunctive relief
and indemnification; (b) the rights, powers, privileges, remedies and interests
of any party under the Purchase Agreement and the other Transaction Documents or
under applicable law as may be exercised or otherwise enforced in bad faith or a
commercially unreasonable manner; and (c) any term or provision of the Purchase
Agreement or any of the other Transaction Documents which purportedly permits a
party to exercise or otherwise enforce powers and privileges and pursue rights
and remedies in a manner impermissible under or otherwise inconsistent with
applicable law or public policy, from time to time in effect.

            We express no opinion with respect to any provision of the Purchase
Agreement or any of the other Transaction Documents: (a) that purports to make a
choice of law of any jurisdiction as the law governing such document; (b) that
purports to designate a specific forum or venue in which disputes between the
parties are to be resolved; (c) by which a party purports to accept jurisdiction
of any court or forum; or (d) that restricts a party from competing or
soliciting customers or employees.

            In rendering the opinions set forth in numbered Paragraph 5 below,
we have assumed that each of the Shareholders which is a natural person has the
legal capacity to enter

<PAGE>

into the Purchase Agreement and the Transaction Documents (although we have no
knowledge of any facts that would lead us to believe any Shareholder does not
have such legal capacity) and with respect to each of the Shareholders who are
entities, with your permission we have relied on the opinion of Zellermayer,
Pelossof, Adv. (a copy of which is attached hereto as EXHIBIT A) as to such
Shareholder's right, power and authority to enter into the Purchase Agreement
and the Transaction Documents.

            Our opinions in clause (ii) of paragraph 2 below and in paragraph 3
below are limited to laws and regulations normally applicable to transactions of
the type contemplated in the Transaction Documents and do not extend to
licenses, permits and approvals necessary for the conduct of the Company's
business. In addition and without limiting the previous sentence, we express no
opinion herein with respect to the effect of any land use, environmental or
similar law, any state or federal antitrust law or any local law. Further, we
express no opinion as to the effect of or compliance with any state or federal
laws or regulations applicable to the transactions contemplated by the
Transaction Documents because of the nature of the business of any party thereto
other than the Company.

            This opinion letter relates solely to the laws of the State of New
York and the applicable federal laws of the United States and we express no
opinion with respect to the effect or applicability of the laws of other
jurisdictions. Members of our firm are admitted to the Bar in the State of New
York.

            Based upon and subject to the foregoing, we are of the opinion that:

            1.    Assuming the due authorization, execution and delivery of the
Transaction Documents by the parties thereto including the Company, each of the
Transaction Documents to which the Company is a party constitutes a legal, valid
and binding obligation of the Company enforceable by the Buyer against the
Company in accordance with its respective terms.

            2.    Neither the execution or delivery by the Company of the
Transaction Documents to which it is a party, nor the consummation by the
Company at the Closing of the transactions contemplated thereby, will (i)
violate or be in conflict with any United States federal or New York law that to
our knowledge is applicable to the Company or (ii) violate or contravene any
judgment, decree, injunction or order known to us of any United States federal
or New York court or any arbitrator or governmental agency or authority, having
jurisdiction over the Company or its properties or by which the Company may be
bound.

            3.   No consents, approvals or authorizations of or filings with
any governmental authority of the State of New York or the United States are
required or necessary on the part of the Company in connection with the
execution, delivery and performance at the Closing by the Company of the
Transaction Documents, except for such consents, approvals, authorizations or
filings which have been obtained, waived or made prior to the date hereof, and
we are not aware of any proceedings, or any threat of any proceedings, that
question the validity thereof.

<PAGE>

            4.   We are not aware of any private or governmental action, suit,
proceeding, claim, arbitration or investigation pending, or threatened in
writing, before any agency, court or tribunal against the Company or any
judgment, decree or order in each case that questions the validity of the
Transaction Documents.

            5.   Each of the Transaction Documents to which the Shareholders
are a party constitutes the valid and binding agreement of each such
Shareholder, enforceable in accordance with its terms, except insofar as the
indemnification provisions contained therein may be limited by applicable law.

                  This opinion letter is rendered as of the date hereof and is
limited to the matters stated herein and no opinion is inferred or may be
implied beyond the matters expressly stated. This opinion letter is delivered
solely to you pursuant to the terms of the Purchase Agreement, and it may not be
delivered to, or relied upon by, any other person without the prior written
consent of this firm. We assume no obligation to advise you of facts,
circumstances, events or developments which hereafter may be brought to our
attention and which may alter, affect or modify the opinions expressed herein.

                                                                       EXHIBIT E


                           REPURCHASE OPTION AGREEMENT


      THIS AGREEMENT is made this 12th day of October 2000, between LivePerson,
Inc., a Delaware corporation (the "Company"), Eitan Ron and Tal Goldberg (each a
"Founder" and together, the "Founders"), and First Union National Bank, as
Escrow Agent (the "Escrow Agent").

      WHEREAS, reference is made to the Stock Purchase Agreement, dated as of
the date hereof, by and among the Company, HumanClick Ltd. ("HumanClick") and
the shareholders listed on the signature pages thereto (the "Shareholders") (the
"Purchase Agreement"), pursuant to which the shareholders, including the
Founders, have agreed to exchange their shares of HumanClick for shares of the
Company's common stock, $0.001 par value per share (the "Common Stock"), of
which 2,085,732 shares of Common Stock will be acquired by the Founders (the
Founders' Stock);

      WHEREAS, the execution and delivery of this Agreement is a condition
precedent to the transactions contemplated by the Purchase Agreement; and

      WHEREAS, the parties hereto desire to agree upon the terms upon which the
Founders' Stock may be repurchased by the Company in the event a Founder's
employment with HumanClick is terminated.

      NOW THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements hereinafter set forth, the parties hereto agree as follows:

      1.    REPURCHASE OPTION.

            (a) In the event of (i) the voluntary termination which is not Good
Reason termination, or (ii) involuntary termination for Cause, of a Founder's
employment with or services to HumanClick, the Company shall have, upon the date
of such termination (as reasonably fixed and determined by the Company), an
irrevocable, exclusive option ("Repurchase Option") for a period of ninety (90)
days (subject to Section 1(d) hereof) from such date to repurchase, at a price
equal to the lower of (i) the average closing price for a share of the Company's
Common Stock as quoted on the Nasdaq Stock Market for the 30 trading days
following the date of such termination (the "Market Price") and (ii) seven
dollars ($7.00) per share, all or any portion of such Founders' Stock that are
Unreleased Founders' Stock (as hereinafter defined). The Company may exercise
its Repurchase Option by giving written notice to the applicable Founder (with a
copy to the Escrow Agent) and, at the option of the Company, (i) by delivering
to such Founder a check in the amount of the repurchase price for the Founders'
Stock being repurchased, or (ii) by canceling such of the applicable Founder's
indebtedness to the Company equal to the repurchase price for the Founders'
Stock being repurchased, or (iii) a combination of (i) and (ii) equal to the
repurchase price for the Founders' Stock being repurchased. Upon delivery of
such notice and payment of the repurchase price, the Company shall become the
legal and beneficial owner of the Founders' Stock being repurchased (and all


<PAGE>

rights and interests therein or relating thereto) and shall have the right to
retain and transfer to its own name the number of shares of Founders' Stock
being repurchased.

            (b) Whenever the Company shall have the right to repurchase
Founders' Stock hereunder, the Company may designate and assign one or more
employees, officers, directors or shareholders of the Company or other persons
or organizations to exercise all or a part of the Repurchase Option and purchase
all or a part of such Founders' Stock.

            (c) Notwithstanding the provisions of Section 1(a) hereunder, in the
event of (a) the sale of all or substantially all of the assets of the Company,
or (b) the consummation of a consolidation or a merger in which the Company is
not the surviving entity (other than a consolidation or merger in which the
shareholders of the Company immediately before the consolidation or merger hold,
immediately after the consolidation or merger, securities representing more than
50% of the voting power and equity of the surviving entity) (such events, a
"Change-in-Control Event"), the Repurchase Option shall be exercisable by the
Company or its successors and assigns at a per share price equal to the higher
of: (i) the per share price paid in such transaction, and (ii) the lower of (x)
the Market Price and (y) seven dollars ($7.00) per share.

            (d) Notwithstanding the provisions of Section 1(a) hereunder, in the
event of the (i) voluntary termination which is not for Good Reason, or (ii)
involuntary termination for Cause, of a Founder's employment with or services to
HumanClick, prior to the Termination Date (as that term is defined in that
certain Escrow Agreement, dated of even date hereof, by and among the Company,
HumanClick Ltd., First Union National Bank (as Escrow Agent), and Eitan Ron (as
Shareholders' Agent) (the "Escrow Agreement")), then the Repurchase Option
period for any Unreleased Founders' Stock that has been held in escrow pursuant
to the Escrow Agreement shall end on the later of three business days after (x)
the date on which a Founder's shares are first released pursuant to Section 5(b)
of the Escrow Agreement (the "Release Date") or (y) the date after the Release
Date on which there are no shares subject to Outstanding Claim Notices under the
Escrow Agreement or (z) the date that is 30 days after the date of such
termination.

      2.    RELEASE OF SHARES FROM REPURCHASE OPTION.

            (a) Seventy-five percent (75%) of each Founders' Stock shall be
subject to the Company's Repurchase Option as of the Closing Date (as defined in
the Purchase Agreement) (the "Vesting Start Date"); provided that it is
understood that such portion of each Founders' Stock shall be inclusive of the
shares held in escrow pursuant to the Escrow Agreement. The Founders' Stock
subject to the Repurchase Option of each Founder shall be released from the
Company's Repurchase Option as follows: (i) the portion (if any) of each
Founder's shares subject to the Escrow Agreement which have not been released to
Indemnified Parties in satisfaction of Damages shall be released from the
Company's Repurchase Option at the first anniversary of the Vesting Start Date;
and (ii) one-third of the shares of such Founder's Founders' Stock subject to
the Repurchase Option shall be released from the Company's Repurchase Option at
the second and third anniversary of the Vesting Start Date (respectively),
provided that in each case the applicable Founder's employment by or services to
HumanClick has not been terminated voluntarily (excluding voluntary termination
for Good Reason) or for


                                       2
<PAGE>

Cause prior to the date of any such release and the Company has not exercised
its Repurchase Option pursuant to Section 1 hereunder. On the termination of the
employment of a Founder by HumanClick not for Cause or in case of termination
due to death or disability or by the Founder for Good Reason, all Unreleased
Founders' Stock held by such Founder shall be immediately released from the
Company's Repurchase Option and shall be delivered to such Founder.

            (b) Any of the shares of Founders' Stock which have not yet been
released from the Company's Repurchase Option are referred to herein as
"Unreleased Founders' Stock." Unreleased Founders' Stock shall be deemed to
exclude any shares released to any Indemnified Party or subject to Claim Notices
on the Release Date under the Escrow Agreement; provided that if any shares
subject to a Claim Notice on the Release Date are to be subsequently released to
the Founders (or a trustee) pursuant to the Escrow Agreement, such released
shares shall then be deemed to be Unreleased Founders' Stock until released from
the Company's Repurchase Option pursuant to the terms of this Agreement and with
joint written direction provided to the Escrow Agent executed by both parties in
the form attached hereto as EXHIBIT A.

            (c) The shares of Founders' Stock which have been released from the
Company's Repurchase Option shall be delivered to an Israeli trustee, the
identity of which shall be delivered to the Company and the Escrow Agent within
30 days of the date hereof (the "Israeli Trustee"), for the benefit of the
applicable Founder at such Founder's request.

            (d) Employment with HumanClick constitutes at-will employment. This
Agreement shall not confer upon any Founder any right with respect to
continuation of employment by HumanClick, nor shall it interfere with or affect
in any manner the right or power of HumanClick, or a parent or subsidiary of
HumanClick, to terminate any Founder's employment at any time or for any reason,
with or without Cause. For purposes of this Agreement, "Cause" and "Good Reason"
shall have the meaning attributed to such term in such Founder's Employment
Agreement (as defined in the Purchase Agreement).

      3.    RESTRICTION ON TRANSFER. Except for the escrow described in Section
4 or transfer of the Unreleased Founders' Stock to the Company or its assignees
contemplated by this Agreement, none of the shares of Unreleased Founders' Stock
or any beneficial interest therein shall be transferred, encumbered or otherwise
disposed of in any way until the release of such Founders' Stock from the
Repurchase Option in accordance with the provisions of this Agreement.

4.    ESCROW OF SHARES.

            (a) The Founders' Stock subject to the Repurchase Option shall be
held by the Escrow Agent, along with stock assignments executed by each Founder
in blank, until the expiration of the Company's option to repurchase such
Founders' Stock as set forth above. The fees of the Escrow Agent shall be paid
by the Company.

            (b) The Escrow Agent is hereby directed to permit transfer of the
Founders' Stock only in accordance with this Agreement or instructions signed by
both parties. In the event further instructions are desired by the Escrow Agent,
the Escrow Agent shall be entitled to rely upon directions executed by a
majority of the authorized number of the Company's Board of


                                       3
<PAGE>

Directors. The Escrow Agent shall have no liability for any act or omission
hereunder while acting in good faith in the exercise of the Escrow Agent's own
judgment. In the event the Escrow Agent is directed to transfer the Founders'
Stock to the Founders, the Escrow Agent shall transfer such shares to the
Israeli Trustee for the benefit of the applicable Founder with the joint written
direction executed by both parties in the form attached hereto as EXHIBIT A.

            (c) If the Company or any assignee exercises its Repurchase Option
hereunder, the Escrow Agent, upon receipt of written notice of such option
exercise from the proposed transferee and a written evidence that the amounts
due for the shares have been paid to the Founder, shall take all steps necessary
to accomplish such transfer.

            (d) When the Repurchase Option has been exercised or expires
unexercised or a portion of the Founders' Stock has been released from such
Repurchase Option, upon the applicable Founder's request the Escrow Agent shall
promptly cause a new certificate to be issued for such released Founders' Stock
and shall deliver such certificate to the Israeli Trustee for the benefit of the
applicable Founder with the joint written direction executed by both parties in
the form attached hereto as EXHIBIT A.

            (e) Subject to the terms hereof, the applicable Founder shall have
all the rights of a shareholder with respect to such Founders' Stock subject to
the Repurchase Option while they are held in escrow, including without
limitation, the right to vote the shares of Founders' Stock subject to the
Repurchase Option and receive any cash dividends declared thereon. If, from time
to time during the term of the Company's Repurchase Option, there is (i) any
stock dividend, stock split or other change in the Founders' Stock subject to
the Repurchase Option, or (ii) any merger or sale of all or substantially all of
the assets of or other acquisition of the Company, any and all new, substituted
or additional securities to which each Founder is entitled by reason of the
Purchaser's ownership of the Shares shall be immediately subject to this escrow,
deposited with the Escrow Agent and included thereafter as "Founders' Stock
subject to the Repurchase Option" for purposes of this Agreement and the
Company's Repurchase Option.

      5.    GENERAL TERMS AND STANDARDS REGARDING THE ESCROW AGENT.
Notwithstanding any terms of this Agreement to the contrary, each term of this
Agreement, including without limitation each of the stated duties and
responsibilities of the Escrow Agent set forth herein, shall be subject to the
following terms and conditions:

            (a) The duties, responsibilities and obligations of the Escrow Agent
shall be limited to those expressly set forth in this Agreement (and the duty to
exercise reasonable care in the physical safekeeping of any property held in
escrow hereunder), and no implied duties, responsibilities or obligations shall
be read into this Agreement against the Escrow Agent. Without limiting the
generality of the foregoing, the Escrow Agent shall have no duty to take action
to preserve or exercise rights in any property held by it hereunder (including,
without limitation, against prior parties or otherwise).

            (b) The Escrow Agent shall not be subject to, bound by, charged with
notice of or be required to comply with or interpret any agreement or document
(including without limitation the Purchase Agreement) between or among the
interested parties (whether or not reference to any such other agreement or
documents is expressed herein) other than this Agreement.


                                       4
<PAGE>

            (c) The Escrow Agent shall in no instance be under any duty to give
any property held by it hereunder any greater degree of care than it gives its
own similar property. The Escrow Agent shall not be required to invest any funds
held hereunder, and shall not be obligated to pay interest on uninvested funds.
All amounts received by the Escrow Agent (and any credits to the Escrow Account)
shall be conditional upon collection (and actual receipt by the Escrow Agent of
final payment). In no event shall the Escrow Agent have any obligation to
advance funds.

            (d) The Escrow Agent may rely upon, and shall be protected in acting
or refraining from acting upon, any written notice, instruction, statement,
request, waiver, order, judgement, certification, consent, receipt or other
paper or document furnished to it (not only as to genuineness, but also as to
its due execution and validity, the genuineness of signatures appearing thereon
and as to the truth and accuracy of any information therein contained), which it
in good faith believes to be genuine and signed or presented by the proper
person.

            (e) Neither the Escrow Agent nor any of its directors, officers or
employees shall be liable to anyone for any error of judgment, or for any act
done or step taken or omitted to be taken by it or any of its directors,
officers or employees, or for any mistake of fact or law, or for anything which
it, or any of its directors, officers or employees, may do or refrain from doing
in connection with or in the administration of this Agreement, unless and except
to the extent the same constitutes gross negligence, bad faith or willful
misconduct on the part of the Escrow Agent. In no event shall the Escrow Agent
be liable for any indirect, punitive, special or consequential damages, or any
amount in excess of the value of the Unreleased Founders' Stock (as of the date
of the action or omission giving rise to liability).

            (f) The Escrow Agent shall not be deemed to have notice of any fact,
claim or demand with respect hereto unless actually known by an officer charged
with responsibility for administering this Agreement or unless in writing
received by the Escrow Agent and making specific reference to this Agreement.

            (g) No provision of this Agreement shall require the Escrow Agent to
expend or risk its own funds, or to take any legal or other action hereunder
which might in its judgement involve it in, or require it to incur in connection
with the performance of its duties hereunder, any expense or any financial
liability unless it shall be furnished with indemnification acceptable to it.

            (h) Any permissive right of the Escrow Agent to take any action
hereunder shall not be construed as duty.

            (i) All indemnifications contained in this Agreement shall survive
the resignation or removal of the Escrow Agent, and shall survive the
termination of this Agreement.

            (j) The Escrow Agent is not responsible for the recitals appearing
in this Agreement. The recitals shall be deemed to be statements of the
interested parties to this Agreement.

            (k) The Escrow Agent has no responsibility for the sufficiency of
this Agreement for any purpose. Without limiting the foregoing, if any security
interest is referred to herein, the


                                       5
<PAGE>

Escrow Agent shall have no responsibility for, and makes no representation or
warranty as to, the creation, attachment or perfection of any such security
interest or the sufficiency of this Agreement therefor.

            (l) Nothing in this Agreement shall obligate the Escrow Agent to
qualify to do business or act in any jurisdiction in which it is not presently
qualified to do business, or be deemed to impose upon the Escrow Agent the
duties of a trustee. The duties of the Escrow Agent under this Agreement are
strictly ministerial in nature.

            (m) In no event shall the Escrow Agent have any liability for any
failure or inability of any of the interested parties to perform or observe his
or its duties under the Agreement, or by reason of a breach of this Agreement by
either of the interested parties. In no event shall the Escrow Agent be
obligated to take any action against any of the interested parties to compel
performance hereunder.

            (n) The Escrow Agent shall in no instance be obligated to commence,
prosecute or defend any legal proceedings in connection herewith. The Escrow
Agent shall be authorized and entitled, however, in any instance to commence,
prosecute or defend any legal proceedings in connection herewith, including
without limitation any proceeding it may deem necessary to resolve any matter or
dispute, to obtain a necessary declaration of rights, or to appoint a successor
upon resignation (and after failure by the interested parties to appoint a
successor, as provided in Section 10).

            (o) Whenever the terms hereof call for any notice, payment or other
action on a day which is not a business day, such payment or action may be
taken, or such notice given, as the case may be, on the next succeeding business
day. As used herein, "business day" shall mean any day other than a Saturday or
Sunday, or any other day on which the Escrow Agent is closed for business.

            (p) In the event of any ambiguity or uncertainty under this
Agreement, or in any notice, instruction, or other communication received by the
Escrow Agent hereunder, the Escrow Agent may, in its reasonable discretion,
refrain from taking action, and may retain the Unreleased Founders' Stock, until
and unless it receives written instruction signed by all interested parties, or
a decision by a court of competent jurisdiction which eliminates such
uncertainty or ambiguity.

            (q) If at any time Escrow Agent is served with any judicial or
administrative order, judgement, decree, writ or other form of judicial
administrative process which in any way relates to or affects the Unreleased
Founders' Stock (including but not limited to orders of attachment or
garnishment or other forms of levies or injunctions or stays relating to the
Unreleased Founders' Stock), Escrow Agent is authorized to comply therewith in
any manner as it or its legal counsel reasonably deems appropriate; and if the
Escrow Agent complies with any such judicial or administrative order, judgement,
decree, writ or other form of judicial or administrative process, Escrow Agent
shall not be liable to any of the Parties hereto or to any other person or
entity notwithstanding that though such order, judgement, decree, writ or
process may be subsequently modified, annulled, set aside, vacated, found to
have been without proper jurisdiction, or otherwise determined to have been
without legal force or effect.


                                       6
<PAGE>

            (r) The Escrow Agent shall have no liability for the actions or
omissions of any transfer agent, book-entry depository, nominee, correspondent,
subagent or subcustodian, except to the extent that such action or omission of
any transfer agent, book-entry depository, nominee, correspondent, subagent or
subcustodian was caused by the Escrow Agent's own gross negligence, bad faith or
willful misconduct.

            (s) The parties understand that the Unreleased Founders' Stock is
not subject to an effective registration statement at the time of this
Agreement, and that the Escrow Agent shall not be responsible for fluctuations
in the market in connection with any transfer of the shares.

      6.    INDEMNIFICATION.

            (a) GENERAL. Each of the Founders (jointly and severally as a group)
and the Company, jointly and severally, hereby covenant and agree to indemnify
the Escrow Agent for, and to defend and hold harmless the Escrow Agent from and
against, any and every loss, liability, damage, claim, cost and expense of any
nature incurred or suffered by the Escrow Agent and arising out of or in
connection with this Agreement or the administration of this Agreement or the
performance or observance by the Escrow Agent of its responsibilities or
services under this Agreement (including but not limited to reasonable attorneys
fees and other costs and expenses of defending or preparing to defend against
any claim or liability), unless and except to the extent such loss, liability,
damage, cost or expense shall be caused by the Escrow Agent's own willful
misconduct, bad faith or gross negligence..

            (b) TAX-RELATED MATTERS. Each of the Founders (jointly and severally
as a group) and the Company, jointly and severally, agree to assume any and all
obligations imposed now or hereafter by any applicable tax law with respect to
this Agreement, and, without limiting the generality of Section 6(a) above,
hereby agree to indemnify and hold the Escrow Agent harmless from and against
any taxes, additions for late payment, interest, penalties and other expenses,
that may be assessed against the Escrow Agent on any payment or other activities
under this Agreement. The Company and each of the Founders undertake to instruct
the Escrow Agent in writing with respect to the Escrow Agent's responsibility
for withholding and other taxes, assessments or other governmental charges,
certifications and governmental reporting in connection with its acting as
Escrow Agent under this Agreement. Each of the Founders (severally as a group)
and the Company, jointly and severally, agree to indemnify and hold the Escrow
Agent harmless from any liability on account of taxes, assessments or other
governmental charges, including without limitation the withholding or deduction
of or the failure to withhold or deduct same, and any liability for failure to
obtain proper certifications or to properly report to governmental authorities,
to which the Escrow Agent may be or become subject in connection with or which
arises out of this Agreement, including costs and expenses (including reasonable
legal fees), interest and penalties. The interested parties shall each promptly
provide Escrow Agent with appropriate IRS Forms W-9 for taxpayer identification
number certifications, or Forms W-8 for nonresident alien certifications in
connection with any payments to be made to them.

                  Purchase Agreement.

            (b)   THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED

                                    Attention: Corporate Trust Group

      Notwithstanding anything herein to the contrary, any party may give any
notice, request, demand, claim or other communication hereunder by personal
delivery or telecopy, but no such notice, request, demand, claim or other
communication shall be deemed to have been duly given unless and until it
actually is received by the party for whom it is intended. Any party may change
the address to which notices, requests, demands, claims and other communications
hereunder are to be delivered by giving the other parties notice in the manner
herein set forth. Copies of any notice, request, demand, claim or other
communication hereunder by personal delivery or telecopy given to the Escrow
Agent by either party, shall be delivered to the other party as soon thereafter
as practicable.

      10.   SUCCESSOR ESCROW AGENT. In the event the Escrow Agent becomes
unavailable or unwilling to continue in its capacity herewith, the Escrow Agent
may resign and be discharged from its duties or obligations hereunder by
delivering a resignation to the parties, not less than 60 days prior to the date
when such resignation shall take effect. The Company may appoint a successor
Escrow Agent with the consent of the Founders, which shall not be unreasonably
withheld. If, within such notice period, the Company provides to the Escrow
Agent written instructions with respect to the appointment of a successor Escrow
Agent and directions for the transfer of any Unreleased Founders' Stock then
held by the Escrow Agent to such successor, the Escrow Agent shall act in
accordance with such instructions and promptly transfer such Unreleased
Founders' Stock to such designated successor. If no successor is so appointed,
the Escrow Agent may apply to a court of competent jurisdiction for such
appointment.

      11.   GENERAL PROVISIONS.

            (a) This Agreement shall be governed by the internal laws of the
State of New York without reference to such State's principles of conflicts of
law. This Agreement and the Purchase Agreement (including all exhibits and
schedules thereto) represent the entire agreement between the parties with
respect to the issuance and sale of the Purchaser Shares (as defined in the
Purchase Agreement) to the Shareholders, and may only be modified or amended in
writing signed by all parties.

            (b) The rights and benefits of the Company under this Agreement
shall be transferable to the Company's successor and assigns upon a
Change-in-Control Event, or to any one or more persons or entities with the
prior written consent of the Founders, and all covenants and agreements
hereunder shall inure to the benefit of, and be enforceable by, the Company's
successors and assigns. The rights and obligations of the Founders under this
Agreement may only be assigned with the prior written consent of the Company.

            (c) Either party's failure to enforce any provision or provisions of
this Agreement shall not in any way be construed as a waiver of any such
provision or provisions, nor prevent that party thereafter from enforcing each
and every other provision of this Agreement. The rights granted both parties
herein are cumulative and shall not constitute a


                                       9
<PAGE>

waiver of either party's right to assert all other legal remedies available to
it under the circumstances.

            (d) The Founders agree upon request to execute any further documents
or instruments necessary or desirable to carry out the purposes or intent of
this Agreement.

            (e) The Founders understand that each of the Founders (and not the
Company) shall be responsible for each Founder's own federal, state, local or
foreign tax liability and any of the Founder's other tax consequences that may
arise as a result of the transactions contemplated by this Agreement. The
Founders shall rely solely on the determinations of the Founders' tax advisors
or their own determinations, and not on any statements or representations by the
Company or any of its agents, with regard to all such tax matters.

            (f) The Company undertakes to execute the joint written direction in
the form attached hereto as EXHIBIT A whenever required pursuant to the terms of
this Agreement.

                  [Brobeck, Phleger & Harrison LLP letterhead]

HumanClick Ltd.
33 Bnei Zion
Israel 60910

Ladies and Gentlemen:

            We have acted as counsel for LivePerson, Inc., a Delaware
corporation (the "Buyer"), in connection with its purchase of all of the
outstanding capital stock of HumanClick Ltd., a private company organized under
the laws of the State of Israel (the "Seller"), pursuant to the Stock Purchase
Agreement dated as of October 12, 2000 between the Buyer, the Seller and the
shareholders of the Seller named in SCHEDULE I thereto (the "Shareholders")
(such agreement, the "Purchase Agreement"). This opinion is being rendered to
you pursuant to Section 7.03(c) of the Purchase Agreement. Capitalized terms
used herein and not otherwise defined shall have the same meaning given to such
terms in the Purchase Agreement.

            In connection with the opinions expressed herein, we reviewed the
following:

                  (i)   the Purchase Agreement;

                  (ii)  the Escrow Agreement dated as of October 12, 2000
                        between the Buyer, the Seller, First Union National Bank
                        (as Escrow Agent) and Eitan Ron (as Shareholders'
                        Agent);

                  (iii) the Repurchase Option Agreement dated as of October 12,
                        2000 between the Buyer, Eitan Ron and Tal Goldberg;

                  (iv)  The Certificate of Good Standing of the Company
                        certified by the Secretary of State of the State of
                        Delaware on October 11, 2000 (the "Delaware
                        Certificate");

                  (v)   The Certificates of Good Standing of the Company
                        certified by the Secretary of State of the States of
                        California and New York on October 11, 2000 (the
                        "Out-of-State Certificates"); and

                  (vi)  originals or copies of such corporate documents or
                        records of the Buyer and such other documents as we have
                        deemed necessary or appropriate as a basis for the
                        opinions hereinafter expressed.


<PAGE>

The documents listed as items (i) though (iii) above are referred to herein as
the "Transaction Documents").

            In connection with the opinions expressed herein we have made such
examination of matters of law and of fact as we considered appropriate or
advisable for purposes hereof. As to matters of fact material to the opinions
expressed herein, we have relied upon the representations and warranties as to
factual matters contained in and made by the Buyer pursuant to the Purchase
Agreement and upon certificates and statements of government officials and of
officers of the Buyer. We have assumed for the purposes of this opinion letter
the genuineness of all signatures, the legal capacity of natural persons, the
authenticity of the documents submitted to us as originals, the conformity to
the original documents of all documents submitted to us as certified, facsimile
or photostatic copies, and the authenticity of the originals of such copies.

            In rendering this opinion letter we have also assumed: (A) that the
Transaction Documents have been duly and validly executed and delivered by or on
behalf of each party thereto other than the Buyer, that each party to the
Transaction Documents other than the Buyer has the power to enter into and
perform its obligations thereunder and that the Transaction Documents constitute
legal, valid, binding and enforceable obligations of each such party; (B) that
the representations and warranties made in the Transaction Documents by the
parties thereto other than the Buyer are true and correct; and (C) that each
party to the Transaction Documents other than the Buyer has filed any required
state franchise, income or similar tax returns and has paid any required state
franchise, income or similar taxes.

            Whenever a statement herein is qualified by the expressions "known
to us," "to our knowledge," "we are not aware" or a similar phrase or expression
with respect to our knowledge of matters of fact, it is intended to mean that
our knowledge is based upon the records, documents, instruments and certificates
described above and the current actual knowledge of the attorneys in this Firm
who have devoted substantive attention to the transactions contemplated by the
Transaction Documents or who are presently involved in substantive legal
representation of the Buyer (but not including any constructive or imputed
notice of any information) and that we have not otherwise undertaken any
independent investigations for the purpose of rendering this opinion.
Specifically, but without limitation, we have not searched the dockets of any
courts and we have made no inquiries of securities holders or employees of the
Company, other than such officers.

            This opinion letter relates solely to the laws of the State of New
York, the General Corporation Law of the State of Delaware, and applicable
federal laws of the United States, and we express no opinion with respect to the
effect or applicability of the laws of other jurisdictions.

            For purposes of the matters addressed in paragraph (1) below
relating to the valid existence and good standing of the Company under the laws
of Delaware, we have relied solely upon the Delaware Certificate. For purposes
of the matters addressed in paragraph (1) below relating to the good standing,
due qualification or similar status of the Company in California and New York,
we have relied solely upon our review of the Out-of-State Certificates.


                                       14
<PAGE>

            Based upon and subject to the foregoing, and subject to the further
assumptions, limitations, qualifications and exceptions set forth herein, we are
of the opinion that:

            1. The Buyer is a corporation duly incorporated, validly existing
and in good standing under the laws of the State of Delaware, and the Buyer has
the requisite corporate power and authority to own its properties and to conduct
its business as, to our knowledge, it is presently conducted. The Buyer is
qualified to do business as a foreign corporation in the States of California
and New York.

            2. The Buyer has the requisite corporate power and authority to
execute, deliver and perform the Purchase Agreement and the other Transaction
Documents. Each of the Purchase Agreement and the other Transaction Documents
has been duly and validly authorized by the Buyer, has been duly executed and
delivered by an authorized officer of the Buyer and constitutes a legal, valid
and binding obligation of the Buyer, enforceable by the Seller against the Buyer
in accordance with its terms.

            3. Neither the execution or delivery by the Buyer of the Transaction
Documents nor the consummation by the Buyer at the Closing of the transactions
contemplated thereby will (i) violate any provision of the Certificate of
Incorporation or Bylaws of the Buyer, (ii) violate or be in conflict with any
federal, Delaware General Corporation Law or New York State law which to our
knowledge is applicable to the Buyer, (iii) to our knowledge, violate or
contravene any judgment, decree, injunction or order of any federal, Delaware
corporate or New York State court, or any arbitrator or governmental agency or
authority, having jurisdiction over the Buyer or its properties or by which the
Buyer may be bound, or (iv) constitute a material breach of, or result in a
material default under, any term or provision of any indenture, agreement or
other instrument to which Buyer is a party or by which Buyer or any of its
properties are bound and which has been filed by Buyer with the United States
Securities and Exchange Commission.

            4. No consents, approvals or authorizations of or filings with any
governmental authority operating under the laws of the United States, the
Delaware General Corporation Law or New York State are required or necessary on
the part of the Buyer in connection with the execution, delivery and performance
at the Closing by the Buyer of the Transaction Documents, except for such
consents, approvals, authorizations or filings which have been obtained, waived
or made prior to the date hereof, and we are not aware of any proceedings, or
any threat of any proceedings, that question the validity of the Transaction
Documents.

            5. The shares of Purchaser Common Stock to be delivered in exchange
for shares of Company Shares, when issued as contemplated by the Stock Purchase
Agreement, (i) will be validly issued, fully paid and non-assessable, and (ii)
will not be issued in violation of any statutory preemptive rights or, to our
knowledge, similar contractual rights granted by Buyer.

            The foregoing opinions are subject to the following additional
limitations, qualifications, assumptions and exceptions:

            A.    The enforceability of the Buyer's obligations under the
Transaction Documents may be subject to or limited by (i) bankruptcy,
insolvency, reorganization, arrangement, moratorium, fraudulent transfer and
other similar laws affecting the rights of


<PAGE>

creditors generally; and (ii) general equitable principles (whether relief is
sought in a proceeding at law or in equity), including, without limitation,
concepts of materiality, reasonableness, good faith, and fair dealing.

            B.    We express no opinion as to provisions of the Transaction
Documents purporting to establish an evidentiary standard or to authorize
conclusive determinations by the Seller or any other person or allowing the
Seller or any other person to make determinations in its sole discretion.

            C.    We also express no opinion as to:

                  (i) provisions of the Transaction Documents pursuant to which
the Buyer agrees to make payments without set-off, defense or counterclaim;

                  (ii) provisions relating to indemnification, contribution or
exculpation, to the extent any such provision is contrary to public policy or
prohibited by law (including, without limitation, federal and state securities
laws);

                  (iii) any provision providing for the exclusive jurisdiction
of a particular court or purporting to waive rights to trial by jury, service of
process or objections to the laying of venue or to forum on the basis of forum
NON CONVENIENS, in connection with any litigation arising out of or pertaining
to the Transaction Documents;

                  (iv) provisions purporting to waive either illegality as a
defense to the performance of contract obligations or any other defense to such
performance which cannot, as a matter of law, be effectively waived; (v) any
provision permitting modification of the Transaction Documents only by means of
an agreement in writing signed by the parties thereto; and

                  (vi) any provision requiring payment of attorneys' fees,
except to the extent a court determines such fees to be reasonable.

            D.    Our opinions in clause (ii) of paragraph 3 above and in
paragraph 4 above are limited to laws and regulations normally applicable to
transactions of the type contemplated in the Transaction Documents and do not
extend to licenses, permits and approvals necessary for the conduct of the
Buyer's business. In addition and without limiting the previous sentence, we
express no opinion herein with respect to the effect of any land use,
environmental or similar law, any state or federal antitrust law, any state or
federal securities law or any local law. Further, we express no opinion as to
the effect of or compliance with any state or federal laws or regulations
applicable to the transactions contemplated by the Transaction Documents because
of the nature of the business of any party thereto other than the Buyer.

            E.    We also express no opinion as to Section 10.06 of the Purchase
Agreement and similar provisions of the other Transaction Documents to the
extent that they purport to exclude conflict of law principles under New York
law.

            This opinion is rendered as of the date first written above solely
for your benefit in connection with the Purchase Agreement and may not be
delivered to, quoted or relied upon by any person other than you, or for any
other purpose, without our prior written consent. Our opinion is expressly
limited to the matters set forth above and we render no opinion, whether by
implication or otherwise, as to any other matters relating to the Buyer. We
assume no obligation to advise you of facts, circumstances, events or
developments which hereafter may be brought to our attention and which may
alter, affect or modify the opinions expressed herein.

                                       Very truly yours,

                  (name of employee)

--------------------------------------------------
                     (address)

--------------------------------------------------

            The following confirms an agreement between me and HumanClick LTD.
(the "Company"), which is a material part of the consideration for my employment
by the Company:

            1.    I understand that the Company possesses and will possess
Proprietary Information which is important to its or its clients' business. For
purposes of this Agreement, "Proprietary Information" is all information,
whether or not made verbally or in writing or other tangible form, that was or
will be developed, created, or discovered by or on behalf of the Company or its
clients, or which became or will become known by, or was or is conveyed to the
Company or its clients, which has commercial value in the Company's or its
clients' business. "Proprietary Information" includes, but is not limited to,
trade secrets, ideas, methodologies, skills, knowledge, computer programs,
computer codes, databases, database criteria, user profiles, algorithms,
modules, scripts, features and modes of operation, designs, technology, ideas,
know-how, processes, data, techniques, internal documentation, improvements,
inventions (whether patentable or not), works of authorship, technical,
business, financial, client, marketing, and product development plans,
forecasts, the salaries and terms of compensation of other employees, client and
supplier lists, contacts at or knowledge of clients or prospective clients of
the Company, and other information concerning the Company's or its clients'
actual or anticipated products or services, business, research or development,
or any information which is received in confidence by or for the Company from
any other person. I understand that my employment creates a relationship of
confidence and trust between me and the Company with respect to Proprietary
Information.

            2.    I understand that the Company possesses or will possess
"Company Materials" which are important to its or its clients' business. For
purposes of this Agreement, "Company Materials" are documents or other media or
tangible items that contain or embody Proprietary Information or any other
information concerning the business, operations or plans of the Company or its
clients, whether such documents have been prepared by me or by others. "Company
Materials" include, but are not limited to, computers, computer software,
computer disks, tapes, printouts, source, HTML and other code, flowcharts,
schematics, designs, graphics, drawings, photographs, charts, graphs, notebooks,
customer lists, sound recordings, other tangible or intangible manifestation of
content, and all other documents whether printed, typewritten, handwritten,
electronic, or stored on computer disks, tapes, hard drives, or any other
tangible medium, as well as samples, prototypes, models, products and the like.

            3.    In consideration of my employment by the Company and the
compensation received by me from the Company from time to time, I hereby agree
as follows:


<PAGE>

                  a.  All Proprietary Information and all title, patents, patent
rights, copyrights, trade secret rights, and other intellectual property and
rights anywhere in the world (collectively "Rights") in connection therewith
shall be the sole property of the Company. I hereby assign to the Company any
Rights I may have or acquire in such Proprietary Information. At all times, both
during my employment by the Company and after its termination, I will keep in
confidence and trust and will not use or disclose any Proprietary Information or
anything relating to it without the prior written consent of an officer of the
Company. During the term of this Agreement and thereafter, I shall not disclose
to any third party the terms and conditions of my employment by the Company,
except to close family members, legal, tax, and accounting professionals who
require the information to provide services to me, or as required by law.

                  b.  All Company Materials shall be the sole property of the
Company. I agree that during my employment by the Company, I will not deliver
any Company Materials to any person or entity outside the Company, except as I
am required to do in connection with performing the duties of my employment. I
further agree that, immediately upon the termination of my employment by me or
by the Company for any reason, or during my employment if so requested by the
Company, I will return all Company Materials, apparatus, equipment and any other
physical property of the Company, or any reproduction of such property,
excepting only (i) my personal copies of records relating to my compensation;
and (ii) my copy of this Agreement. I shall also provide any information, such
as passwords or codes, necessary to allow the Company to fully utilize its
property.

                  c.  I will promptly disclose in writing to my immediate
supervisor, with a copy to the President or Chief Executive Officer of the
Company, or to any persons designated by the Company, all "Developments" (which
term includes, without limitation, any work of authorship, discovery,
improvement, invention, design, graphic, source, HTML and other code, trade
secret, technology, algorithms, computer program, audio, video or other files or
content, idea, design, process, technique, know-how and data, whether or not
patentable or copyrightable), made, conceived, reduced to practice, developed or
discovered by me, either alone or jointly with others, during the term of my
employment and occurring in the course of or arising from the performance of my
work under this Agreement. I will also disclose to the President or the Chief
Executive Officer of the Company Developments conceived, reduced to practice, or
developed by me within six (6) months after the termination of my employment
with the Company; such disclosures shall be received by the Company in
confidence (to the extent they are not assigned in Section 3(d) below) and do
not extend the assignment made in Section 3(d) below. I will not disclose
Developments covered by Section 3.d. to any person outside the Company unless I
am requested to do so by management personnel of the Company.

                  d.  I agree that all Developments which I make, conceive,
reduce to practice discover or develop (in whole or in part, either alone or
jointly with others) during my employment and occurring in the course of or
arising from the performance of my work under this Agreement shall be the sole
property of the Company. Unless the Company decides otherwise, the Company shall
be the sole owner of all Rights in connection therewith. All copyright-protected
Developments are and at all times shall remain "work made for hire". I hereby
assign to the Company any and all of my Rights to any Developments, absolutely
and forever, throughout the world and for the full term of each and every such
Right, including renewal or extension of any such term.

                  e.  I agree to perform, during and after my employment, all
acts deemed necessary or desirable by the Company to permit and assist it, at
the Company's expense, in evidencing, perfecting, obtaining, maintaining,
defending and enforcing Rights and/or my assignment with respect to such
Developments in any and all countries. Such acts may include, but are not
limited to, execution of documents and assistance or cooperation in legal
proceedings. I hereby irrevocably designate and appoint the Company and its duly
authorized officers and agents, as my agents and attorneys-in-fact to act for
and


                                       2
<PAGE>

in my behalf and instead of me, to execute and file any documents and to do all
other lawfully permitted acts to further the above purposes with the same legal
force and effect as if executed by me.

                  f.  Any assignment of copyright hereunder includes all rights
of paternity, integrity, disclosure and withdrawal and any other rights that may
be known as or referred to as "moral rights" (collectively "Moral Rights"). To
the extent such Moral Rights cannot be assigned under applicable law and to the
extent the following is allowed by the laws in the various countries where Moral
Rights exist, I hereby waive such Moral Rights and consent to any action of the
Company that would violate such Moral Rights in the absence of such consent. I
will confirm any such waivers and consents from time to time as requested by the
Company.

                  g.  I have attached hereto a complete list of all existing
Developments to which I claim ownership as of the date of this Agreement and
that I desire to specifically clarify are not subject to this Agreement, and I
acknowledge and agree that such list is complete. If no such list is attached to
this Agreement, I represent that I have no such Developments at the time of
signing this Agreement.

                  h.  During the term of my employment and for one (1) year
thereafter, I will not encourage or solicit any employee or consultant of the
Company to leave the Company for any reason. However, this obligation shall not
affect any responsibility I may have as an employee of the Company with respect
to the bona fide hiring and firing of Company personnel.

                  i.  I agree that during my employment with the Company and for
a period of one (1) year thereafter (the "Non-Competition Period"), I will not,
as an employee, officer, director, shareholder (other than an owner of 1% or
less of the outstanding shares of any publicly-traded company), consultant,
partner or in any other capacity, engage in any employment, business, or
activity that is in any way competitive with the Business of the Company, and I
will not assist any other person or organization in competing with the Company
or in preparing to engage in competition with the Business of the Company.
Similarly, during the Non-Competition Period, I will not solicit any clients of
the Company, on my own behalf or on behalf of any third party, in connection
with any goods or services that are competitive with the Business of the
Company. "Business of the Company" shall be defined to mean any goods or
services offered by the Company to clients, or planned by the Company to be
offered to clients. The provisions of this paragraph shall apply both during
normal working hours and at all other times including, but not limited to,
nights, weekends and vacation time, while I am employed by the Company, as well
as to the entire Non-Competition Period.

                  j.  I represent that my performance of all the terms of this
Agreement will not breach any agreement to keep in confidence proprietary
information acquired by me in confidence or in trust prior to my employment by
the Company. I have not entered into, and I agree I will not enter into, any
agreement either written or oral in conflict herewith or in conflict with my
employment with the Company. I also understand that I am prohibited from using
or disclosing, in the course of my employment with the Company, any proprietary
information, trade secrets, or tangible property of any other person or company,
including prior employers, without the express authority to do so.

                  k.  I represent that any and all Developments that I may
create under this Agreement will be original and shall not defame Company, its
other employees, officers, directors, consultants or agents or any third party
or constitute a violation of the rights of privacy of Company's other employees
or any third party.

            4.    I agree that this Agreement is not an employment contract and
that I have the right to resign and the Company has the right to terminate my
employment at any time, for any reason,


                                       3
<PAGE>

with or without cause, subject to the provisions of any written employment
agreement between the Company and me.

            5.    I agree that this Agreement does not purport to set forth all
of the terms and conditions of my employment, and that as an employee of the
Company I have obligations to the Company which are not set forth in this
Agreement.

            6.    I agree that my obligations under paragraphs 3(a) through 3(f)
and paragraph 3(h) of this Agreement shall continue in effect after termination
of my employment, regardless of the reason or reasons for termination, and
whether such termination is voluntary or involuntary on my part, and that the
Company is entitled to communicate my obligations under this Agreement to any
future employer or potential employer of mine.

            7.    I agree that any dispute in the meaning, effect or validity of
this Agreement shall be resolved in accordance with the laws of the State of
Israel without regard to the conflict of laws provisions thereof. I further
agree that if one or more provisions of this Agreement are held to be illegal or
unenforceable under applicable Israeli law, such illegal or unenforceable
portion(s) shall be limited or excluded from this Agreement to the minimum
extent required so that this Agreement shall otherwise remain in full force and
effect and enforceable in accordance with its terms.

            8.    This Agreement shall be effective as of the date I execute
this Agreement and shall be binding upon me, my heirs, executors, assigns, and
administrators and shall inure to the benefit of the Company, its subsidiaries,
successors and assigns.

            9.    This Agreement can only be modified by a subsequent written
agreement executed by the President or Chief Executive Officer of the Company.

                  I HAVE READ THIS AGREEMENT CAREFULLY AND I UNDERSTAND AND
      ACCEPT THE OBLIGATIONS WHICH IT IMPOSES UPON ME WITHOUT RESERVATION. NO
      PROMISES OR REPRESENTATIONS HAVE BEEN MADE TO ME TO INDUCE ME TO SIGN THIS
      AGREEMENT. I SIGN THIS AGREEMENT VOLUNTARILY AND FREELY, IN DUPLICATE,
      WITH THE UNDERSTANDING THAT ONE COUNTERPART WILL BE RETAINED BY THE
      COMPANY AND THE OTHER COUNTERPART WILL BE RETAINED BY ME.

anything related to it without the prior written consent of an officer of the
Company. Contractor acknowledges that any disclosure or unauthorized use of
Proprietary Information will constitute a material breach of this Agreement and
cause substantial harm to the Company for which damages would not be a fully
adequate remedy and, therefore, in the event of any such breach, in addition to
other available remedies, the Company shall have the right to obtain injunctive
relief.

                  e.   All Company Materials shall be the sole property of the
Company. Contractor agrees that during the term of this Agreement, Contractor

or deliver any Company Materials to any person or entity outside the Company,
except as required to do in connection with performance of the Services under
this Agreement. Contractor further agrees that, immediately upon the Company's
request and in any event upon completion of the Services, Contractor shall
deliver to the Company all Company Materials, any document or media which
contains Results, apparatus, equipment and other physical property or any
reproduction of such property, excepting only Contractor's copy of this
Agreement. At all times before or after completion of the Services, the Company
shall have the right to examine the Results and any

materials relating thereto to ensure Contractor's compliance with the provisions
of this Agreement.

                  f.   Contractor will promptly disclose in writing to the
President of the Company, or to any persons designated by the Company, all

discoveries, improvements, inventions, designs, graphics, source code, HTML and
other code, trade secrets, technology, algorithms, computer programs, ideas,
processes, techniques, know-how, methods of doing business and data, whether or
not patentable), made, conceived, reduced to practice, developed or discovered
by Contractor, either alone or jointly with others, during the term of this
Agreement and occurring in the course of or arising from the performance of the
work of Contractor under this Agreement. Contractor shall also disclose to the
Chief Executive Officer of the Company all Developments conceived, reduced to
practice or developed by Contractor within six (6) months of the termination of
this Agreement that relate to any Proprietary Information of Company. Such
disclosures shall be received by Company in confidence (to the extent that they
are not assigned in (g) below) and do not extend the assignment made in (g)
below.

                  g.   Contractor agrees that all Developments which Contractor
makes, conceives, reduces to practice, develops or discovers (in whole or in
part, either alone or jointly with others) during the term of this Agreement and
occurring in the course of or arising from the performance of the work of
Contractor under this Agreement in connection with the Services or which relate
to any Proprietary Information shall be the sole property of the Company. All
Developments that are copyright works will be "works made for hire" to the
extent allowed by law, and to the extent that such copyright works cannot
qualify as "works made for hire" as a matter of law, such copyright works shall
be covered by the assignment in the next sentence. Contractor agrees to assign
and hereby assigns to the Company any and all Rights to all Developments and the
Company shall be the sole owner of all Rights in connection with all
Developments.

                  h.   Contractor agrees to perform, during and after the term
of this Agreement, all acts deemed necessary or desirable by the Company to
permit and assist it in evidencing, perfecting, obtaining, maintaining,
defending and enforcing Rights and/or Contractor's assignment with respect to
such Developments in any and all countries. Such acts may include, but are not
limited to, execution of documents and assistance or cooperation in legal
proceedings. Contractor hereby irrevocably designates and appoints the Company
and its duly authorized officers and agents, as Contractor's agents and
attorneys-in-fact to act for and on behalf and instead of Contractor, to execute
and file any documents and to do all other lawfully permitted acts to further
the above purposes with the same legal force and effect as if executed by
Contractor.

                  i.   Any assignment of copyright hereunder includes all rights
of paternity, integrity, disclosure and withdrawal and any other rights that may
be known as or referred to as "moral rights" (collectively "Moral Rights"). To
the extent such Moral Rights cannot be assigned under applicable law and to the
extent the following is allowed by the laws in the various countries where Moral
Rights exist, Contractor hereby waives such Moral Rights and consents to any
action of the Company that would violate such Moral Rights in the absence of


                                       9

such consent. Contractor will confirm any such waivers and consents from time to
time as requested by the Company.

services for any other person or entity other than the Company or its
subsidiaries.

                  k.   Consultant will not, during the term of this Agreement

such client of the Company on behalf of any individual or entity other than the
Company for services of the same or similar type as those provided by the
Company to the client. "Client" shall be defined as any individual or entity for
whom the Company has performed services during the six (6) month period prior to
the termination of this Agreement.

                  l.   Contractor agrees that during the term of this
Agreement, Contractor will not engage in any employment, business, or activity
that is in any way competitive with the business or proposed business of the
Company, and Contractor will not assist any other person or organization in
competing with the Company or in preparing to engage in competition with the
business or proposed business of the Company.

                  m.   Contractor represents that performance of all the
terms of this Agreement will not breach any agreement to keep in confidence
proprietary information acquired by Contractor in confidence or in trust prior
to the execution of this Agreement. Contractor has not entered into, and
Contractor agrees not to enter into, any agreement either written or oral that
conflicts or might conflict with Contractor's performance of the Services under
this Agreement.

                  n.   Contractor represents that any and all Developments
that it will create under this Agreement will be original and shall not defame
Company, its employees, officers, directors, Contractors or agents or any third
party or constitute a violation of the rights of privacy of Company's employees
or any third party.

                  o.   If any Rights or Developments assigned hereunder or
any Results are based on, or incorporate, or are improvements or derivatives of,
or cannot be reasonably made, used, reproduced and distributed without using or
violating technology or Rights owned or licensed by Contractor and not assigned
hereunder, Contractor hereby grants the Company a perpetual, worldwide
royalty-free, non-exclusive sublicensable right and license to exploit and
exercise all such technology and Rights in support of the Company's exercise or
exploitation of any Results or assigned Rights or Developments (including any
modifications, improvements and derivatives thereof).

                  p.   Contractor represents that, other than the Developments,
if any, disclosed to the Company in writing that Contractor claims to have
developed independent of this Agreement, Contractor does not own any
Developments that relate in any way to the Services.

defend Company against any and all loss, liability, damage, claims, demands or
suits and related costs and expenses to persons or property that arise, directly
