     entered into the Voting Trust Agreement, dated as of July 1, 1999, with

     Voting Trust Agreement, the Limited Partnerships agreed to transfer the
     Ordinary Shares beneficially owned by them to the Voting Trustee as trustee
     for the Voting Trust. The Limited Partnerships retain full discretion to
     transfer the Ordinary Shares subject to the Voting Trust as well as all
     economic rights pertaining to such Ordinary Shares, but, so long as such
     Ordinary Shares are beneficially owned by any of the Limited Partnerships,
     Goldman Sachs, GS Group or any affiliate of any Limited Partnership,
     Goldman Sachs, or GS Group, the Voting Trustee is obligated to vote such
     shares with the majority vote cast of all other Ordinary Shares or, in
     certain circumstances, in proportion to the vote cast of all other Ordinary
     Shares or to abstain from voting. The Voting Trust is irrevocable and
     perpetual in duration unless terminated in limited circumstances, including
     most transfers, bankruptcy of the Company, and if the aggregate percentage
     ownership interest in the Company of the Limited Partnerships, Goldman
     Sachs and GS Group drops below 5%, among others.

                             VOTING TRUST AGREEMENT

                  THIS VOTING TRUST AGREEMENT, dated as of July 1, 1999 (this

                              W I T N E S S E T H :

                  WHEREAS, each Shareholder deems it to be in its best interest
to assign, transfer and vest the voting power of the number of ordinary shares
("Voting Stock") of BackWeb Technologies Ltd., a corporation organized under the
laws of Israel, (the "Company") indicated on Schedule 1 hereto opposite the name
of each such Shareholder in the Voting Trustee in accordance with the terms of
this Agreement;

                  WHEREAS, each Shareholder intends to deposit such shares of
Voting Stock owned by such person in the voting trust created by this
instrument; and

                  WHEREAS, each Shareholder desires to appoint GS Capital

         and (ii) the Memorandum of Association and Articles of Association of
         BackWeb Technologies Ltd. (the "Company") and (b) are subject to the
         Voting Trust Agreement. By accepting this certificate, the holder
         hereof agrees to be bound by all of the provisions of such agreement
         and instruments, which agreement and instruments are available for
         inspection by the holder hereof at the principal office of the Company
         in Israel during regular business hours."

                  (b) Upon withdrawal of shares of Voting Trust Stock from the

otherwise transfer any Voting Trust Certificate held by it. Except as otherwise
provided herein, all options, rights of purchase and other powers and
privileges, including all registration rights, all economic rights and benefits
and all transfer rights, affecting the Voting Trust Stock represented by a
Voting Trust Certificate shall attach to such Voting Trust Certificate.

                  (b) The Voting Trustee shall keep a record on its books of the

shares of Voting Trust Stock beneficially owned by such holder.

                  (c) Should any Voting Trust Certificate be mutilated or be
lost, destroyed or stolen, the Voting Trustee may, in its uncontrolled
discretion, issue and deliver in exchange therefor and upon cancellation of such
mutilated certificate or in lieu of such lost, destroyed or stolen certificate a

         successor statute, the Voting Trustee shall abstain from voting the
         Voting Trust Stock;

                  (iii) with respect to any matters that under current or future

                  SECTION 6. Subscription. In the event any shares or other
securities of the Company are offered for subscription to the holders of the
shares held by the Voting Trustee, the Voting Trustee shall promptly upon
receipt of notice of said offer mail a copy thereof to each registered Voting
Trust Certificate holder. Provided the Voting Trustee receives in due time a
request from such registered Voting Trust Certificate holders to subscribe for
such shares or other securities together with a certified or cashiers' check for
the requisite sum of money for the subscription of such shares or other
securities, the Voting Trustee shall make such subscription and payment and,
upon receipt from the Company of the certificates for shares or other securities
so subscribed for, the Voting Trustee shall issue to such holders a Voting Trust
Certificate in respect thereof, if the same are Voting Stock or other voting
securities of the Company, but if the same are securities other than Voting
Stock or other voting securities of the Company, the Voting Trustee shall
deliver such securities to the registered Voting Trust Certificate holder on
whose behalf the subscription was made.

                  SECTION 7. Successor Voting Trustee. (a) The Voting Trustee
may, at any time, resign by giving written notice to the registered holders of
the Voting Trust Certificates to take effect 30 days thereafter or upon prior
acceptance thereof by the registered holders of the Voting Trust Certificates.

                  (b) In the event of resignation of the Voting Trustee, the
successor Voting Trustee shall be such person as may be designated by the
holders of Voting Trust Certificates representing a majority of the Voting Trust
Stock.

                  (c) Notwithstanding the provisions of Section 7(b) hereof, no
person designated as a successor Voting Trustee shall serve as a Voting Trustee
hereunder until such person has agreed in writing to be bound by the obligations
contained in this Agreement whereupon such successor Voting

                                        4

<PAGE>   5
Trustee shall succeed to and become vested with all the rights, powers,
privileges and duties of a Voting Trustee under this Agreement.

                  SECTION 8. Termination. (a) This Agreement shall become
effective upon the date hereof and continue in effect until terminated according
to subsection (b) of this Section or until all Voting Trust Stock has been
withdrawn from the Voting Trust pursuant to this Agreement.

                  (b) This Agreement may not be terminated and the Voting Trust
shall be irrevocable (and any attempt to revoke the Voting Trust shall
constitute a breach of this Agreement) set forth in subsection (a) of this
Section, except as follows:

                  (i) the Voting Trust shall be revoked and this Agreement shall
         terminate if, at the written request of the Shareholders'
         Representative, a majority of the board of directors of the Company
         votes to revoke the Voting Trust and terminate this Agreement provided
         that such majority must include Mr. Joseph Gleberman if he is a member
         of the board of directors at the time of the vote;

                  (ii) upon the sale, assignment or other transfer of Voting
         Trust Stock to someone other than Goldman, Sachs & Co., an affiliate of
         Goldman, Sachs & Co., a Shareholder or an affiliate of a Shareholder
         (for purposes of this Agreement, "affiliate" shall mean any person who,
         as determined by the Shareholders' Representative, directly or
         indirectly, controls, is controlled by or is under common control with
         a Shareholder or affiliate thereof, and "control" shall mean the
         ability to direct the actions and policies of that person through
         ownership or otherwise), then as to such transferred shares the Voting
         Trust shall be revoked and this Agreement shall terminate, and the
         relevant Voting Trust Certificates shall immediately be surrendered to
         the Voting Trustee in exchange for their corresponding shares of Voting
         Trust Stock in accordance with subsection (c) of this Section;

                  (iii) the Voting Trust shall be revoked and this Agreement
         shall terminate upon the written request of the Shareholders'
         Representative delivered to the Voting Trustee and the other holders of
         Voting Trust Certificates in the event any of the following occurs:

                           (A) the Company files for bankruptcy or otherwise
                  voluntarily seeks protection from creditors, or is adjudged to
                  be insolvent or is subject to an involuntary petition in
                  bankruptcy not dismissed within 60 days;

                           (B) a proposal is submitted to the shareholders of
                  the Company to approve a merger or other business combination
                  in which holders of Voting Trust Certificates will receive
                  securities issued by someone other than the Company;

                           (C) if the Voting Trust Stock represents less than 5%
                  of the issued and outstanding Voting Stock; or

                           (D) Mr. Joseph Gleberman shall cease to be a member
                  of the Company's board of directors.

                  (c) Upon the termination of this Agreement or upon the
withdrawal of shares from the Voting Trust as provided in this Agreement, the
Voting Trustee shall promptly act to comply with Section 2(b) hereof, and, in
exchange for and upon surrender of the Voting Trust Certificates, shall deliver
to the respective holders thereof or with respect to shares so withdrawn, as the
case may be, the new certificates for shares of the Company received from the
Transfer Agent together with a duly executed share transfer deed conveying such
shares in exchange for such Voting Trust Certificates; provided, however, that
prior to delivery of such certificates by the Voting Trustee, the holders of the
Voting Trust Certificates shall deposit with the Voting Trustee the cost of any
stamp tax or other tax payable in connection with the transfer of shares.

                  SECTION 9. Compensation. The Voting Trustee shall be paid an
initial fee of US$7,500 on the date hereof and an annual fee of US$7,500 in
advance on the date hereof and each anniversary thereafter until this Agreement
is terminated or a successor Voting Trustee is appointed pursuant to Section 7
hereof. In addition, the Voting Trustee shall have the right to incur and pay
such reasonable expenses and disbursements and to employ such counsel as it may
deem necessary and proper in the performance of its duties hereunder. Any and
all such fees, expenses or disbursements incurred shall be charged pro rata to
the holders of the Voting Trust Certificates and each of such holders agrees to
assume and pay its pro rata share of such charges and expenses.

                  SECTION 10.  Concerning the Voting Trustee.

                  (a) The Voting Trustee shall have all requisite power,
authority and discretion as shall be necessary or appropriate to enable it to
take all such actions as such Voting Trustee is required to take pursuant to
this Agreement. Except as otherwise provided in Section 4(b) hereof, the Voting
Trustee shall have no liability hereunder except for its own gross negligence or
willful misconduct.

                  (b) The Voting Trustee may consult with any counsel, banker,
broker, accountant or other professional adviser satisfactory to it and the
written opinion of such person shall be full and complete authorization and
protection in respect of any reasonable action taken, omitted to be taken or
suffered by him hereunder in good faith and in accordance with such opinion.

                  (c) The Voting Trustee shall be protected and shall incur no
liability for, or in respect of, any action taken or omitted to be taken or
anything suffered by him in reliance upon any notice, direction, consent,
certificate, affidavit, statement or other paper or document reasonably believed
by him to be genuine and to have been presented or signed by the proper parties.

                  (d) The Voting Trustee shall be obligated to perform such
duties and only such duties as are herein specifically set forth, and no implied
duties or obligations shall be read into this Agreement. The Voting Trustee
shall not be under any obligation (i) to take any action hereunder which may
tend to involve him in any expense or liability for which, in its reasonable
opinion, the Voting

                                        6

<PAGE>   7

Trustee believes it will not be reimbursed and (ii) to give a bond or other
security for the faithful performance of its duties as such.

                  (e) Nothing herein contained shall disqualify the Voting
Trustee from dealing or contracting with the Company or any of its subsidiaries
with respect to any matter or thing whatsoever. The Voting Trustee, any
affiliate of the Voting Trustee, or any firm of which the Voting Trustee may be
a member and any corporation of which the Voting Trustee may be a shareholder,
director or officer, as the case may be, may deal and contract with the Company
or any of its subsidiaries with respect to any matter or thing and be or become
interested in a matter or transaction in which the Company or any of its
subsidiaries has an interest, and the Voting Trustee or such other person, as
the case may be, shall not be responsible to the Company or any of its
subsidiaries or to any shareholder thereof for any profit realized by, from or
through any such transaction or contract.

                  SECTION 11. Indemnification.

                  (a) The holders of the Voting Trust Certificates, jointly and
severally, covenant and agree to indemnify and hold harmless the Voting Trustee
and its directors, officers, employees and agents (each an "Indemnified Party"),
without duplication, from and against any and all claims, damages, losses,
liabilities, obligations, actions, suits, costs, disbursements and expenses
(including reasonable fees and expenses of counsel) incurred by any Indemnified
Party arising out of, from, or in conjunction with the Voting Trustee's
execution of or performance or inaction under this Agreement, except to the
extent such claim, damage, loss, liability, obligation, action, suit, cost,
disbursement or expense is found in a final, non-appealable judgment by a court
of competent jurisdiction to have resulted from such Indemnified Party's gross
negligence or willful misconduct.

                  (b) The indemnities set forth in this Section shall be in
addition to any other obligations or liabilities of the holders of the Voting
Trust Certificates hereunder or at common law or otherwise and shall survive the
termination of this Agreement.

                  SECTION 12. Other Obligations of the Voting Trustee and the
Company.

                  (a) The Voting Trustee shall file a copy of this Agreement in
the principal office of the Company in Israel. The Company shall keep such copy
open to the inspection of any shareholder of the Company, or any beneficiary of
the Voting Trust, daily during business hours at such principal office.

                  (b) The Voting Trustee shall give written notice to the
holders of the Voting Trust Certificates if a meeting of the Company's
shareholders is called at which the Voting Trustee shall be asked to vote, or if
in lieu of such meeting the Voting Trustee shall be asked to act by written
consent, on any corporate action requiring approval of the Company's
shareholders. Such notification shall be delivered immediately after the Voting
Trustee receives notice of any such meeting of the Company's shareholders or any
such proposed action by written consent. Such notification need not be given by
the

                                        7

<PAGE>   8
Voting Trustee to any holder of a Voting Trust Certificate who also owns other
shares of Voting Stock and is thereby entitled to such notice directly from the
Company.

                  SECTION 13. Shareholders' Representative. The Shareholders and
each of them hereby appoint the Shareholders' Representative as their agent to
act with respect to certain matters set forth in this Agreement, and the
Shareholders' Representative hereby accepts such appointment. The Shareholders'
Representative shall have no liability hereunder to the Shareholders or any of
them for any action taken or inaction by it with respect to this Agreement.

                  SECTION 14. Transfer of Voting Trust Certificates and Voting
Trust Stock. (a) Voting Trust Certificates are non-transferable except to
Goldman, Sachs & Co., an affiliate of Goldman, Sachs & Co., a Shareholder, or an
affiliate of a Shareholder, provided that any such transferee first becomes a
party to this Agreement, and provided further that no such transfer shall be
effective unless, if requested by the Voting Trustee, the transferor, at its own
expense, provides the Voting Trustee with a written opinion of legal counsel
reasonably acceptable to the Voting Trustee that such transfer does not violate
the securities laws of the United States of America or of any State thereof. In
the event of any transfer pursuant to this subsection (a) of this Section, the
Voting Trust Stock represented by the transferred Voting Trust Certificates
shall at all times remain subject to the Voting Trust and this Agreement.

                  (b) Each Shareholder shall have the right to sell, transfer,
pledge or otherwise dispose of the Voting Trust Stock beneficially owned by such
Shareholder represented by its Voting Trust Certificates provided however that
no transfer of Voting Trust Stock to Goldman, Sachs & Co., any affiliate of
Goldman, Sachs & Co., any Shareholder or any affiliate of a Shareholder, shall
be effective unless such transferee first becomes a party to this Agreement and
provided further that such transfer shall not constitute a withdrawal of such
Voting Trust Stock from the Voting Trust and such Voting Trust Stock shall
continue to be subject to the Voting Trust and this Agreement. Upon any transfer
(other than a transfer to Goldman, Sachs & Co., any affiliate of Goldman, Sachs
& Co., any Shareholder or any affiliate of a Shareholder) pursuant to this
subsection (b) purporting to transfer the Shareholder's entire interest in the
relevant shares of Voting Trust Stock whether by sale, gift or foreclosure or
otherwise, such shares shall be withdrawn from the Voting Trust and the
provisions of Section 2(b) and Section 8(c) shall apply, and thereafter this
Agreement shall terminate as concerning such Voting Trust Stock (and such
withdrawn shares shall no longer be considered Voting Trust Stock for purposes
of this Agreement).

                  SECTION 15. Amendments. This Agreement may not be amended,
supplemented or otherwise modified except in a writing signed by or on behalf of
the Voting Trustee and the Shareholders' Representative. If this Agreement shall
be amended, the Voting Trustee shall file a copy of the instrument effecting
such amendment in the principal office of the Company in Israel.

                  SECTION 16. Notices. All notices, consents, approvals and
other communications given or made pursuant hereto shall be in writing and shall
be (a) delivered personally against receipt thereof, (b) sent by overnight
courier, (c) transmitted by telecopier or (d) sent by registered or certified
