                                    WARRANT

NEITHER THIS WARRANT NOR THE WARRANT SHARES AS DEFINED HEREIN HAVE BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE
SECURITIES LAWS. NEITHER THIS WARRANT NOR THE WARRANT SHARES MAY BE SOLD OR
TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR ANY EXEMPTION FROM SUCH
REGISTRATION.

                Dated as of June 30, 2004 (the "Effective Date")

     ClickSoftware Technologies Ltd., an Israeli corporation (the "COMPANY"),
grants IBM United Kingdom Ltd., a British company ("IBM" and each of its
successors and assigns, a "HOLDER") a warrant (this "WARRANT") to purchase the
Warrant Shares at the Purchase Price, PROVIDED, HOWEVER, that the number of
Warrant Shares for which this Warrant shall be exercisable shall be subject to
the vesting schedule set forth in APPENDIX D. Capitalized terms not otherwise
defined have the definitions set forth in APPENDIX A.

     1. EXERCISE AND EXPIRATION OF WARRANT.

          (a)  This Warrant is immediately exercisable and will expire upon the
four-year anniversary of the date hereof. "EXERCISE PERIOD" shall mean the
period of time between the date hereof and the expiration of this Warrant in
accordance with the terms hereof.

          (b)  This Warrant may be exercised during the Exercise Period by the
Holder, in whole or in part, by delivering this Warrant to the Company with
payment of the Purchase Price in U.S. dollars. In lieu of such cash payment, the
Holder may also exercise the Warrant by delivery to the Company of a written
notice of an election to effect a cashless exercise for Warrant Shares pursuant
to this Section 1(b) ("CASHLESS EXERCISE"). To effect a Cashless Exercise, the
Holder will surrender this Warrant for that number of Ordinary Shares determined
by multiplying the number of Warrant Shares to which it would otherwise be
entitled by a fraction, the numerator of which shall be the difference between
(i) the then current Market Price of an Ordinary Share on the date of exercise
and (ii) the Purchase Price, and the denominator of which shall be the then
current Market Price per Ordinary Share. In the event that this Warrant is not
exercised in full immediately prior to the end of the Exercise Period and at
such time the then current Market Price of an Ordinary Share is greater than the
Purchase Price, this Warrant shall be deemed automatically exercised as to the
remaining Warrant Shares at such time by Cashless Exercise without the delivery
of any written notice from the Holder.

          (c)  Upon exercise of this Warrant, the Company will issue to the
Holder (i) a certificate or certificates for the number of full Warrant Shares
to which the Holder shall be entitled upon such exercise plus the value of any
fractional share to which the Holder would otherwise be entitled, and (ii) in
case such exercise is in part only, a new warrant or warrants representing the
remaining Warrant Shares.

                                       1
<PAGE>

          (d)  Each exercise of this Warrant shall be deemed to have been
effected immediately prior to the close of business on the day on which this
Warrant shall have been surrendered pursuant to Section 1(b).

     2. REPRESENTATIONS.

          (a)  By the Holder. The Holder represents and warrants to the Company
as follows:

               (i)  It is an "accredited investor" within the meaning of Rule
501 of the Securities Act. This Warrant is acquired for the Holder's own account
for investment purposes and not with a view to any offering or distribution
within the meaning of the Securities Act and any applicable state securities
laws. The Holder has no present intention of selling or otherwise disposing of
the Warrant or the Warrant Shares in violation of such laws.

               (ii) The Holder has sufficient knowledge and expertise in
financial and business matters so as to be capable of evaluating the merits and
risks of its investment in the Company. The Holder understands that this
investment involves a high degree of risk and could result in a substantial or
complete loss of its investment. The Holder is capable of bearing the economic
risks of such investment.

               (iii) The Holder acknowledges that it has received all the
information it considers necessary or appropriate for deciding whether to
acquire the Warrant and the Warrant Shares. The Holder further acknowledges that
it has had an opportunity to ask questions and receive answers from the Company
regarding the terms and conditions of the offering of the Warrant and the
Warrant Shares.

               (iv) The Holder acknowledges that the Company has indicated that
the Warrant and the Warrant Shares have not been registered under the Securities
Act by reason of their issuance in a transaction exempt from the registration
requirements thereof, and that the Warrant Shares will bear a legend stating
that such securities have not been registered under the Securities Act and may
not be sold or transferred in the absence of such registration or an exemption
from such registration.

          (b)  By the Company. The Company represents and warrants that:

               (i)  It (A) is a corporation duly organized, validly existing and
in good standing under the laws of the state of its organization, (B) has all
requisite power and authority to conduct its business as now conducted and to
consummate the transactions contemplated hereby and (C) is duly qualified to do
business and is in good standing in each jurisdiction in which the character of
the properties owned or leased by it or in which the transaction of its business
makes such qualification necessary and the failure of which would not have a
material adverse effect on the Company.

               (ii) It has outstanding as of the date hereof but before giving
effect to this Warrant, 30,544,782 Ordinary Shares, calculated on a fully
diluted basis, giving effect to the

                                       2
<PAGE>

conversion of all options, warrants, rights and other securities convertible
into, or exchangeable for Ordinary Shares.

               (iii) The execution, delivery and performance by the Company of
this Warrant (A) has been duly authorized by all necessary corporate action, (B)
does not and will not contravene the Company's Memorandum and Articles of
Association and (C) does not and will not contravene any applicable law or any
contractual restriction binding on or otherwise affecting the Company or any of
its properties or result in a default under any agreement or instrument to which
the Company is a party or by which the Company or its properties may be subject.

               (iv) This Warrant has been duly executed and delivered by the
Company, and is a legal, valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms, except as may be
limited by applicable bankruptcy, insolvency, moratorium and other laws
affecting the rights of creditors generally and general principles of equity.

               (v)  Assuming the accuracy of the representations made by the
Holder in Section 2(a) hereof, no authorization, consent, approval, license,
exemption or other action by, and no registration, qualification, designation,
declaration or filing with, any governmental authority is or will be necessary
in connection with the execution and delivery by the Company of this Warrant,
the issuance by the Company of the Warrant Shares, the consummation of the
transactions contemplated hereby, the performance of or compliance with the
terms and conditions hereof, or to ensure the legality, validity, and
enforceability hereof, except for the filing of a Form D under United States
federal and New York state securities laws

               (vi) The Company has reserved solely for issuance and delivery
upon the exercise of this Warrant such number of Ordinary Shares to provide for
the exercise in full of this Warrant.

               (vii) Neither the Company, nor any of its Affiliates, nor any
person acting on its or their behalf, has directly or indirectly made any offers
or sales of any security or solicited any offers to buy any security under
circumstances that would require registration, or the filing of a prospectus
qualifying the distribution, of this Warrant being issued hereby under the
Securities Act or cause the issuance of this Warrant to be integrated with any
prior offering of securities of the Company for purposes of the Securities Act.

     3. CERTAIN AGREEMENTS OF THE COMPANY. The Company agrees as follows:

          (a)  Shares to be Fully Paid. All Warrant Shares will, upon issuance
in accordance with the terms of this Warrant, be validly issued, fully paid, and
nonassessable and free from all taxes, liens, claims and encumbrances.

          (b)  Authorization and Reservation of Shares. During the Exercise
Period, the Company shall have duly authorized a sufficient number of Ordinary
Shares, free from preemptive rights and from any other restrictions imposed by
the Company without the consent of the Holder, to provide for the exercise in
full of this Warrant. The Company shall at all times

                                       3
<PAGE>

during the Exercise Period reserve and keep available out of such authorized but
unissued Ordinary Shares such number of shares to provide for the exercise in
full of this Warrant.

          (c)  Listing. In connection with the Holder's exercise of Registration
Rights hereunder, the Company shall use its best efforts to promptly secure the
listing of the Ordinary Shares issuable upon exercise of this Warrant upon each
national securities exchange or automated quotation system, if any, upon which
Ordinary Shares are then listed or become listed (subject to official notice of
issuance upon exercise of this Warrant) and shall maintain such listing for so
long as any other Ordinary Shares shall be so listed.

          (d)  Certain Actions Prohibited. The Company will not, by amendment of
its Articles of Association or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities, or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed by it hereunder, but will at all times in
good faith assist in the carrying out of all the provisions of this Warrant and
in the taking of all such action as may reasonably be requested by the Holder of
this Warrant in order to protect the exercise privilege of the Holder of this
Warrant against impairment, consistent with the tenor and purpose of this
Warrant.

          (e)  Successors and Assigns. Except as expressly provided otherwise
herein, this Warrant will be binding upon any entity succeeding to the Company
by merger, consolidation, or acquisition of all or substantially all of the
Company's assets.

          (f)  Blue Sky Laws. The Company shall, on or before the date of
issuance of any Warrant Shares, take such actions as the Company shall
reasonably determine are necessary to qualify the Warrant Shares for, or obtain
exemption for the Warrant Shares for, sale to the Holder of this Warrant upon
the exercise hereof under applicable securities or "blue sky" laws of the states
of the United States, and shall provide written evidence of any such action so
taken to the Holder of this Warrant prior to such date; provided, however, that
the Company shall not be required to qualify as a foreign corporation or file a
general consent to service of process in any such jurisdiction.

          (g)  Rule 144 Reports. If the Company becomes subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, but only for so long as
the Company is so subject, the Company shall take all actions reasonably
necessary to enable the Holder to sell the Registrable Securities without
registration under the Securities Act within the limitations of the exemptions
provided by Rule 144 under the Securities Act, as such rule may be amended from
time to time, or any similar rule or regulation hereafter adopted by the SEC,
including filing on a timely basis all reports required to be filed by the
Exchange Act. Upon the request of the Holder, the Company shall deliver to the
Holder a written statement as to whether it has complied with such requirements.

     4. ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES. The Purchase Price
and the number of Warrant Shares may be adjusted from time to time as set forth
in APPENDIX B.

                                       4
<PAGE>

     5. REGISTRATION RIGHTS. The Warrant shall have the Registration Rights set
forth in APPENDIX C. Notwithstanding anything to the contrary contained herein
(including in APPENDIX C), the Holder agrees not to exercise any of the
registration rights set forth in APPENDIX C at any time that it is able to sell
all of its Registrable Securities pursuant to Rule 144 of the Securities Act in
any three (3) month period.

     6. VESTING. The Warrant Shares shall vest in accordance with the vesting
schedule set forth in APPENDIX D.

     7. Treatment of Warrant in the Event of an Acquisition Transaction. If the
Company undertakes an Acquisition Transaction then the Company shall give prompt
notice of such transaction to the Holder. Upon the closing of the Acquisition
Transaction at the Company Acquiror's option, the Company Acquiror may assume
this Warrant and cause provision to be made so that the Holder shall thereafter
be entitled to receive, upon exercise of this Warrant, the Warrant Shares (as
such term is modified in accordance with this Section 6), whereupon the Company
shall be released from this Warrant. If the Company Acquiror does not elect to
assume this Warrant, then (i) this Warrant shall terminate if not assumed by the
Company Acquiror, unless previously exercised by Holder and (ii) notwithstanding
the termination of this Warrant, with respect to the unvested Warrant Shares, if
IBM satisfies the conditions necessary that would have been necessary to cause
some or all of such shares to vest in accordance with the terms of this
Agreement as if this Agreement had continued to be in effect following such
Acquisition Transaction (for instance, if the Company Acquiror Recognizes
Revenues pursuant to the arrangements between IBM and the Company contemplated
hereby), the Company Acquiror shall pay IBM the Cashout Value with respect to
each such portion of the Warrant Shares that would have vested.

     8. TRANSFER, EXCHANGE, AND REPLACEMENT

          (a)  Transferability.

               (i)  The Holder covenants not to transfer this Warrant or the
Warrant Shares except in compliance with this Section 8(a). Subject to
compliance with the transfer restrictions set forth in clauses (ii) and (iii) of
this Section 8(a), this Warrant, the Warrant Shares and the rights granted to
the Holder hereof are freely transferable, in whole or in part, upon surrender
of this Warrant, together with an assignment form, at the office or agency of
the Company referred to in Section 9 below.

               (ii) The Holder shall not effect any transfer except pursuant to
a transaction either registered, or exempt from registration, under the
Securities Act. Prior to any transfer in reliance upon an exemption from such
registration other than Rule 144 of the Securities Act, the Holder shall provide
to the Company an opinion letter from counsel to the Holder (which counsel may
include in-house counsel), reasonably satisfactory to the Company, opining that
such transfer does not require registration under the Securities Act. No sale,
assignment, transfer or pledge of the Warrant Shares shall be made by any holder
thereof to any person unless such person shall first agree in writing to be
bound by the restrictions of this Warrant. Until due presentment for
registration of transfer on the books of the Company, the

                                       5
<PAGE>

Company may treat the registered Holder hereof as the owner hereof for all
purposes, and the Company shall not be affected by any notice to the contrary.

               (iii) Notwithstanding anything in this Warrant to the contrary,
as this Warrant is issued in furtherance of the relationship between the Company
and the initial Holder, this Warrant and any Warrant Shares issued upon its
exercise may not be transferred without the prior written consent of the
Company, which consent may be withheld for any reason, and any purported
transfer of this Warrant or any Warrant Shares issued upon its exercise without
the prior written consent of the Company shall be null and void and of no force
or effect; PROVIDED, that the Holder may transfer to any entity, whether
incorporated or not, that is controlled by IBM, and "control" means the ability,
whether directly or indirectly, to direct the affairs of another by means of
ownership, contract or otherwise.

          (b)  Warrant Exchangeable for Different Denominations. This Warrant is
exchangeable, upon the surrender hereof by the Holder hereof at the office or
agency of the Company referred to in Section 9 below, for new warrants of like
tenor of different denominations representing in the aggregate the right to
purchase the number of Ordinary Shares which may be purchased hereunder, each of
such new warrants to represent the right to purchase such number of shares as
shall be designated by the Holder hereof at the time of such surrender.

          (c)  Replacement of Warrant. Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction, or mutilation of
this Warrant and, in the case of any such loss, theft, or destruction, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company, at its expense, will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

          (d)  Cancellation; Payment of Expenses. Upon the surrender of this
Warrant in connection with any transfer, exchange, or replacement as provided in
this Section 8, this Warrant shall be promptly canceled by the Company. The
Company shall pay all taxes (other than securities transfer taxes) and all other
expenses (other than legal expenses, if any, incurred by the Holder or
transferees) and charges payable in connection with the preparation, execution,
and delivery of warrants pursuant to this Section 8. In the event of any dispute
between the parties concerning the terms and provisions of this Warrant, the
prevailing party shall be entitled to reimbursement from the other party for its
reasonable costs and expenses (including reasonable legal fees) incurred by such
party in connection with such dispute.

          (e)  Warrant Register. The Company shall maintain, at its principal
executive offices (or such other office or agency of the Company as it may
designate by notice to the Holder hereof), a register for this Warrant, in which
the Company shall record the name and address of the person in whose name this
Warrant has been issued, as well as the name and address of each transferee and
each prior owner of this Warrant.

          (f)  No Rights as Shareholder. This Warrant does not entitle the
Holder to any voting rights or other rights as a shareholder of the Company
prior to the exercise hereof.

                                       6
<PAGE>

     9. NOTICES. Any notices required or permitted to be given under the terms
of this Warrant shall be sent by certified or registered mail (return receipt
requested) or delivered personally or by courier or by confirmed telecopy, and
shall be effective five days after being placed in the mail, if mailed, or upon
receipt or refusal of receipt, if delivered personally or by courier, or by
confirmed telecopy, in each case addressed to a party. The addresses for such
communications shall be:

<PAGE>

        E APPENDIX B - ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES

          (a)  Recapitalizations. If the Company's outstanding Ordinary Shares
shall be subdivided into a greater number of shares or a dividend in Ordinary
Shares shall be paid in respect of Ordinary Shares, the Purchase Price in effect
immediately prior to such subdivision or at the record date of such dividend
shall simultaneously with the effectiveness of such subdivision or immediately
after the record date of such dividend be proportionately reduced. If
outstanding Ordinary Shares shall be combined into a smaller number of shares,
the Purchase Price in effect immediately prior to such combination shall,
simultaneously with the effectiveness of such combination, be proportionately
increased.

          (b)  Adjustment in Number of Warrant Shares. When any adjustment is
required to be made in the Purchase Price, the number of Warrant Shares
purchasable upon the exercise of this Warrant shall be changed to the number
determined by dividing (i) an amount equal to the number of shares issuable upon
the exercise of this Warrant immediately prior to such adjustment, multiplied by
the Purchase Price in effect immediately prior to such adjustment, by (ii) the
Purchase Price in effect immediately after such adjustment.

          (c)  Certificate of Adjustment. When any adjustment is required to be
made pursuant to this APPENDIX B, the Company shall promptly mail to the Holder
a certificate setting forth the Purchase Price after such adjustment and setting
forth a brief statement of the facts requiring such adjustment. Such certificate
shall also set forth the kind and amount of stock or other securities or
property into which this Warrant shall be exercisable following such adjustment.

          (d)  ADJUSTMENTS FOR NON-SHARE DIVIDENDS AND DISTRIBUTIONS. In the
event that the Company shall issue or pay to holders of Ordinary Shares a
dividend or other distribution payable other than in securities of the Company,
then and in each such event provision shall be made so that Holder shall receive
upon exercise of this Warrant, in addition to the Warrant Shares issued upon
exercise, the dividend or other distribution which Holder would have received if
it had been the holder of such Warrant Shares at the time of such dividend or
other distribution.

          (e)  Other Notices. In case at any time:

               (i)  the Company shall declare any dividend upon the Ordinary
Shares payable in shares of stock of any class or make any other distribution
(other than dividends or distributions payable in cash out of retained earnings
consistent with the Company's past practices with respect to declaring dividends
and making distributions) to the holders of the Ordinary Shares;

               (ii) the Company shall offer for subscription pro rata to the
holders of the Ordinary Shares any additional shares of stock of any class or
other rights;


                                        1
<PAGE>

               (iii) there shall be any capital reorganization of the Company,
or reclassification of the Ordinary Shares, or consolidation or merger of the
Company with or into, or sale of all or substantially all of its assets to,
another corporation or entity; or

               (iv) there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Company;

then, in each such case, the Company shall give to the Holder (a) notice of the
date on which the books of the Company shall close or a record shall be taken
for determining the holders of Ordinary Shares entitled to receive any such
dividend, distribution, or subscription rights or for determining the holders of
Ordinary Shares entitled to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up, notice of
the date (or, if not then known, a reasonable estimate thereof by the Company)
when the same shall take place. Such notice shall also specify the date on which
the holders of Ordinary Shares shall be entitled to receive such dividend,
distribution, or subscription rights or to exchange their Ordinary Shares for
stock or other securities or property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation, or
winding-up, as the case may be. Such notice shall be given at least thirty (30)
days prior to the record date or the date on which the Company's books are
closed in respect thereto. Failure to give any such notice or any defect therein
shall not affect the validity of the proceedings referred to in clauses (i),
(ii), (iii) and (iv) above.

          (e)  Certain Events. If, at any time during the Exercise Period, any
event occurs of the type contemplated by the adjustment provisions of this
APPENDIX B but not expressly provided for by such provisions, the Company will
give notice of such event, and the Board will make an appropriate adjustment in
the Purchase Price and the number of Ordinary Shares acquirable upon exercise of
this Warrant so that the rights of the Holder shall be neither enhanced nor
diminished by such event.

                        APPENDIX C - REGISTRATION RIGHTS

        (a)     Piggyback Registration.

                (i)     Participation. If the Company elects to file a
registration statement under the Securities Act covering the offer and sale of
any Ordinary Shares (or equity securities converted into Ordinary Shares) in
connection with any public offering (other than a registration statement on Form
S-8 or Form S-4, or their successors, or any other form for a similar limited
purpose, or any registration statement covering only securities proposed to be
issued in exchange for securities or assets of another corporation), the Company
shall give written notice thereof to the Holder at least twenty business days
before filing. The Holder shall have a Piggyback Registration Right to
participate in such offering on a pro rata basis with the Company and any other
holders of the Company's Ordinary Shares upon the giving of notice to the
Company within ten business days of receipt by it of notice from the Company. If
the Holder notifies the Company of its intent to exercise such Piggyback
Registration Right, then, subject to (a)(ii) below, the Company shall include in
such registration statement such number of shares of Registrable Securities as
requested by the Holder. Such Registrable Securities shall be included in the
underwriting for the public offering on the same terms and conditions as the
securities otherwise being sold in such offering.

                (ii)    Underwriters' Cutback. If, in the opinion of the
managing underwriter of such offering the inclusion of all of the shares of
Registrable Securities and other Ordinary Shares requested to be registered
would be inappropriate, then the number of shares of Registrable Securities and
other Ordinary Shares to be included in the offering shall be reduced, with the
participation in such offering to be in the following order of priority: (1)
first, securities to be issued by the Company shall be included, and (2) second,
any other Ordinary Shares required to be included pursuant to any demand
registration right granted to such other holder of Ordinary Shares shall be
included, and (3) third Registrable Securities and any other Ordinary Shares
requested to be included, on a pro rata basis (based upon the number of
registrable securities owned by the Holder and the holders of Ordinary Shares
requesting participation in the offering), shall be included.

                (iii)   Registrant Controls. The Company may decline to file a
Registration Statement after giving notice to any Holder, or withdraw a
Registration Statement after filing and after such notice, but prior to the
effectiveness thereof, provided that such registrant shall promptly notify each
Holder of Registrable Securities in writing of any such action and provided
further that such registrant shall bear all reasonable expenses incurred by such
Holder of Registrable Securities or otherwise in connection with such withdrawn
Registration Statement

                (iv)    Underwriting Agreement. In connection with any
registration under this Section (a) involving an underwriting, the Company shall
not be required to include any Registrable Shares in such registration unless
the Holder accepts the terms of the underwriting as determined by the
underwriters selected by the Company (provided that such terms must be


                                        1
<PAGE>

consistent with this Agreement and provided, further, that any inability of the
Holder to agree with the underwriters shall not restrict the ability of the
Company to proceed with the registration). Notwithstanding anything to the
contrary contained herein, it shall be a condition precedent to the Company's
obligation to take any action pursuant to this section (a) with respect to the
Registrable Securities of the Holder that (i) the Holder furnish to the Company
such information regarding itself, the Registrable Securities held by it, and
the intended method of disposition of such securities as shall be required by
the Company or the managing underwriters, if any, to effect the registration of
the Registrable Securities and (ii) to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the provisions of sections (b) and (c) of this APPENDIX C, the provisions of the
underwriting agreement shall control.

        (b)     Indemnification.

                (i)     Indemnification by the Company. To the extent permitted
by law, the Company agrees to indemnify and hold harmless any Holder of
Registrable Securities which has included Registrable Securities in a
registration statement, its officers, directors and agents and each Person, if
any, who controls such Holder within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act from and against any and all losses,
claims, damages, liabilities and expenses (including reasonable attorneys fees
and costs of investigation) arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in any registration
statement or final prospectus relating to the Registrable Securities or in any
amendment or supplement thereto or in any preliminary prospectus, or arising out
of or based upon any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as such losses, claims, damages, liabilities or
expenses arise out of, or are based upon, any such untrue statement or omission
based upon information furnished in writing to Company by the Holder of the
Registrable Securities or on such Holder's behalf expressly for use therein;
provided, that with respect to any untrue statement or omission made in any
preliminary prospectus, the indemnity agreement contained in this paragraph
shall not apply to the extent that any such loss, claim, damage, liability or
expense results from the fact that a current copy of the prospectus was not sent
or given to the person asserting any such loss, claim, damage, liability or
expense at or prior to the written confirmation of the sale of the Registrable
Securities concerned if it is determined that it was the responsibility of the
Holder of such Registrable Securities to provide such person with a current copy
of the prospectus and such current copy of the prospectus would have cured the
defect giving rise to such loss, claim, damage, liability or expense; PROVIDED,
FURTHER, that the indemnity contained in this section (b)(i) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or expense
if such settlement is effected without the consent of the Company, which consent
shall not be unreasonably withheld. The Company also agrees to indemnify any
underwriters of the Registrable Securities, their officers and directors and
each person who controls such underwriters on substantially the same basis as
that of the indemnification of the Holder of such Registrable Securities
provided in this section (b).

                (ii)    Indemnification by the Holder of Registrable Securities.
To the extent permitted by law, the Holder of Registrable Securities, to the
extent it is selling Registrable


                                        2
<PAGE>

Securities ("SELLING HOLDER"), agrees to indemnify and hold harmless the
Company, its directors and officers and each Person, if any, who controls the
Company within the meaning of either Section 15 of the Securities Act or Section
20 of the Exchange Act to the same extent as the foregoing indemnity from the
Company to the Selling Holder, but only with respect to, and to the extent that,
information furnished in writing by the Selling Holder or on the Selling
Holder's behalf expressly for use in any registration statement or final
prospectus relating to the Registrable Securities (or any amendment or
supplement thereto, or any preliminary prospectus) which contained an untrue
statement or alleged untrue statement of a material fact or omitted or allegedly
omitted to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading. Notwithstanding
anything to the contrary contained herein, the liability of the Holder hereunder
shall be limited to the proportion of any such loss, claim, damage, liability or
expense that is equal to the proportion that the public offering price of the
shares of Registrable Securities sold by the Holder bears to the total public
offering price of all securities sold in such offering. In case any action or
proceeding shall be brought against the Company or its directors or officers, or
any such controlling Person, in respect of which indemnity may be sought against
such Selling Holder, such Selling Holder shall have the rights and duties given
to the Company, and the Company or its directors or officers or such controlling
Person shall have the rights and duties given to such Selling Holder, by the
preceding subsection. The Selling Holder also agrees to indemnify and hold
harmless the underwriters on substantially the same basis of that of the
indemnification of the Company provided in the preceding subsection.

        (c)     Contribution. If the indemnification provided for in this
APPENDIX C is unavailable to the Company or the Selling Holder in respect of any
losses, claims, damages, liabilities, expenses or judgments referred to herein,
then each such indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages, liabilities, expenses and judgments
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other
hand in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities, expenses or judgments, as well as any
other relevant equitable considerations. The relative fault of the Company on
the one hand and of each Selling Holder on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by such party, and the party's relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

        (d)     Registration Expenses and Enforcement.

                (i)     Registrations Rights. The Company shall bear all
Registration Expenses incurred in connection with Piggyback Registration Rights.

                (ii)    Expenses of Registrant. The Company shall pay its
internal expenses (including, without limitation, all salaries and expenses of
its officers and employees performing legal or accounting duties), the expense
of any annual audit, the fees and expenses incurred in


                                        3
<PAGE>

connection with any listing of the securities to be registered on a securities
exchange, and the fees and expenses of any person, including special experts,
retained by the Company.

                (iii)   Enforcement of Registration Rights. Notwithstanding
anything to the contrary contained herein, the Company hereby agrees that each
Holder of Registrable Securities shall be entitled to specific performance of
the registration rights hereunder, and that the Company shall pay any reasonable
costs and expenses, including without reasonable limitation attorneys' fees, in
connection with the enforcement by any Holder of such specific performance;
PROVIDED, HOWEVER, that the Holder shall not have any right to obtain or seek an
injunction restraining or otherwise delaying any registration of securities by
the Company as the result of any controversy that might arise with respect to
the interpretation or implementation of these Registration Rights.

        (e)     Assignment of Registration Rights. Any of the rights of the
Holder hereunder, including the right to have the Company register Registrable
Securities pursuant to this Agreement, may be assigned by the Holder to any
transferee of all of the Warrant or the Registrable Securities if: (i) the
Holder agrees in writing with the transferee or assignee to assign such rights,
and a copy of such agreement is furnished to the Company after such assignment,
(ii) the Company is furnished with written notice of (A) the name and address of
such transferee or assignee, and (B) the securities with respect to which such
registration rights are being transferred or assigned, (iii) following such
transfer or assignment, the further disposition of such securities by the
transferee or assignee is restricted under the Securities Act and applicable
state securities laws, and (iv) such transfer shall have been made in accordance
with the applicable requirements of the Warrant. The transferee, by acceptance
of the transfer of any registration rights hereunder, acknowledges that it takes
such rights subject to the terms and conditions hereof. Upon any transfer of
less than all of its Registrable Securities, the Holder retains registration
rights with respect to Registrable Securities held by it.

                          APPENDIX D - VESTING SCHEDULE

        The Company and the Holder have agreed that the number of Warrant Shares
to be issued under the Warrant shall be determined in accordance with this
Appendix D.

1.      IMMEDIATE WARRANT VESTING

        Upon delivery to the Holder of a duly executed copy of the Warrant,
62,500 Warrant Shares (as may be adjusted pursuant to Appendix B), shall

2.      REVENUE BASED WARRANTS

        (a)     For the purposes of this section:

        "Qualifying Contract" is a contract entered into by the Company and/or
any of its subsidiaries, which the Company and/or any of its subsidiaries and
IBM designate in writing as a "Qualifying Contract" for these purposes.

        "Recognition" or "Recognized" means the earlier of (i) collection of
Revenue, or (ii) recognition of Revenue by the Company for inclusion in its

tax, and excluding all expenses passed through to the client under the
Qualifying Contract and other costs as agreed by IBM and the Company and any of
its subsidiaries) which would be Recognized by the Company as revenue derived
from Qualifying Contracts for inclusion in its consolidated audited financial
statements for the relevant period; provided however that such fees or other
revenue are paid to or collected by the Company within sixty (60) days after the
end of the relevant period. Any fees or other revenue not paid to or collected
by the Company within sixty (60) days after the end of the relevant period shall
be deemed to be Revenue in the period in which such fees or revenue are actually
paid to or collected by the Company.

        (b)     The Holder will become entitled to purchase the following number
of Warrant Shares subject to the Recognition of the minimum Revenue amounts set

Revenue"), such number of Warrant Shares equivalent to the product of (a) the
First Earn-Out Actual Revenue divided by the Full First Earn-Out Amount
multiplied by (b) the Full First Tranche of Warrant Shares will vest in the
Holder (in this case, the difference between the number of Warrant Shares that

will vest in the Holder (in this case, the difference between the number of
Warrant Shares that actually vest with the Holder and the Full Second Tranche of
Warrant Shares shall be referred to as the "Second Earn-Out Warrant Shortfall",
and the difference between the Second Earn-Out Actual Revenue and the Full
Second Earn-Out Amount shall be referred to as the "Second Earn-Out Revenue
Shortfall"); or

                        (C)     if the Company Recognizes Revenues below the

        In addition, if (I) the Company Recognizes Revenue in excess of the Full
Second Earn-Out Amount (the "Second Earn-Out Excess Revenue") and (II) less than
the Full First Tranche of Warrant Shares had vested in the Holder for the First
Earn-Out Period, then additional Warrant Shares equivalent to the product of the

                        (C)     if the Company Recognizes Revenues below the
Third Earn-Out Threshold, no Warrant Shares will vest with the Holder.

        In addition, if (I) the Company Recognizes Revenue in excess of the Full
Third Earn-Out Amount (the "Third Earn-Out Excess Revenue") and (II) less than
the Full First Tranche of Warrant Shares had vested in the Holder for the First
Earn-Out Period and/or less than the Full Second Tranche of Warrant Shares had
vested in the Holder for the Second Earn-Out Period, then additional Warrant
Shares equivalent to the product of the (1) Third Earn-Out Excess Revenue
divided by the aggregate of the First Earn-Out Revenue Shortfall and the Second
Earn-Out Revenue Shortfall multiplied by the (2) aggregate of the First Earn-Out
Warrant Shortfall and the Second Earn-Out Warrant Shortfall will vest with the
Holder, provided that the Holder will be entitled to no more than the Full First
Tranche of Warrant Shares for the First Earn-Out Period and/or the Full Second
Tranche of Warrant Shares for the Second Earn-Out Period, as the case may be.

        (c)     Within 90 days after the end of each of the First Earn-Out
Period, the Second Earn-Out Period and the Third Earn-Out Period, the Company
will prepare and deliver to the Holder a statement of the Revenue for that 12
month period prepared by the Company in accordance with the provisions of this
Appendix D and certified by its chief financial officer for the period (the
"Revenue Notice"). A Revenue Notice shall also contain a computation of the
number of Warrant Shares that have been earned with respect to the period
covered by that Revenue Notice (and of all Warrant Shares which have
cumulatively become available for exercise pursuant to the provisions of this
Appendix).

        (d)     The Holder shall have 30 days from receipt of a Revenue Notice
to object to the information contained therein, by written notice to the Company
(the "Objection Notice"), failing which it shall be deemed accepted. An
Objection Notice shall set out in reasonable detail those aspects of the Revenue
Notice with which the Holder does not agree. Thereafter, if an Objection Notice
has been issued, the Company and the Holder shall use reasonable efforts to
resolve the dispute set out in the Objection Notice. If the Company and the
Holder are unable to resolve any dispute within 30 days of the receipt by the
Company of the Objection Notice, then the Company and the Holder shall jointly
select an accounting firm of national standing in the United States and Israel
to resolve the dispute (the "Independent Accountant"). If the Company and the
Holder are unable jointly to select an accounting firm to act as the Independent
Accountant within the following 3 days, they shall select an accounting firm by
lot (other than the accounting firms engaged by the Company and the Holder to
audit their respective financial statements).

        The Independent Accountant shall be instructed to resolve the matters in
dispute, as set out in the Objection Notice and thereby determine the applicable
Revenue for the period in question. The Independent Accountant shall act as an
expert, not an arbitrator and the determination of the Independent Accountant
shall be binding on the Company, the Holder and their affiliates. The expenses
of the Independent Accountant shall be borne equally by the Company and the
Holder.

        (e)     The Holder shall immediately become entitled to exercise the
Warrant Shares earned under the provisions of paragraphs (b)1, (b)2 and (b)(3)
above, in accordance with the


                                        4

terms of the Warrant, upon the applicable amount of Revenue being agreed or
determined for the relevant period in accordance with the provisions of the
preceding paragraphs, and the Company shall provide the Holder with written
confirmation to that effect within 30 days thereof.
