EXHIBIT 10.7.4

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
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 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

2

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

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 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

3

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

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.

        (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.

4

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

        (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 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.

        (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.

5

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

damage, cost or expense shall be caused by the Escrow Agent's own willful
misconduct, bad faith or gross negligence.

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

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.

        8.    Adjustment for Stock Split.    All references to the number of
shares of Founders' Stock and the purchase price of the shares of Founders'
Stock in this Agreement shall be appropriately adjusted to reflect any stock
split, stock dividend or other change in the Founders' Stock that may be made by
the Company after the date of this Agreement.

        9.    Notices.    All notices, requests, demands, and other
communications under this Agreement shall be in writing and shall be deemed to

This Agreement and the Purchase Agreement (including all exhibits and schedules
