A.      TARGET MARKETS

The primary markets where the Parties will focus their efforts to generate

following industries ("Target Markets"):

        o       ***13
        o       ***14

<PAGE>

B.      SALES OF JOINT SOLUTIONS

1)      The details pertaining to the various scenarios and business opportunity
within the Target Market will be defined in the ATW session and documented in
the Business Plan. The terms relating to the delivery of one Party's Core
Competencies will be governed, as the case may be, either by the SSEA, the MSOW
or by the Sub-contractor Agreement as well by the applicable Transaction
Document.

2)      Each Party will be responsible for compensating their respective sales
forces for any Joint Solution engagements.

C.      OPPORTUNITY MANAGEMENT

1)      CUSTOMER LEAD GENERATION:

The Parties will generally continue their efforts and investments in the lead
generation phase of the sales cycle independently of each other. However, they
agree to actively pass Qualified Leads to each other that are consistent with
the Target Market focus and that meet the requirements established in the
Business Plan. Such leads will be submitted to the Project Office Leader or to
Relationship Executive as the case may be, and may be shared with each other.

2)      SUBMISSION AND CONSIDERATION OF QUALIFIED LEADS:

The Project Office will use the established opportunity management and sales
process, as defined in the Business Plan, to determine whether or not to engage
in a Joint Solution. If a Party declines to participate in a Joint Initiative,
the Party that submitted the Qualified Lead shall be entitled to pursue such
lead alone or in combination with others, without any obligation to the
declining Party. The Party submitting a Qualified Lead acknowledges that, during
the above-described Joint Initiative evaluation process, individuals employed by
the other Party or its Affiliates may be simultaneously engaging (either
directly or in combination with others) in pursuing the same opportunity,
without having been informed of such opportunity by and without the knowledge of
the either the Project Office Leader or the Relationship Executive as the case
may be. The Parties agree that the Party who declines to participate in a Joint
Initiative shall not be considered to be in violation of any obligation under
this Teaming Agreement by virtue of such simultaneous pursuit. If a Party agrees
to participate in a Joint Initiative, the Project Office Leader or the
Relationship Executive as the case may be will, under Section 6.C.4 ).b., below,
determine which Party will act as the Prime. The Parties expressly recognize and
agree that nothing in this Agreement obligates a Party to accept any particular
opportunity as a Joint Initiative .

3)      SALES LEAD TRACKING AND SUPPORT:

The Project Office Leader shall track Qualified Leads, which the Parties have
agreed to pursue as Joint Initiatives and the Parties will provide sales support
as they have mutually agreed upon in writing.

4)      INITIAL ACTIVITIES RELATED TO JOINT INITIATIVES:

After both Parties have accepted an opportunity as a Joint Initiative, the
Project Office Leader and Relationship Executive will take the following steps
in the following order:

        a.      They will evaluate and agree upon a high level description for
                implementation of the Joint Solution for a potential Customer
                (the "Framework"). The Framework will have sufficient detail to
                determine the probable levels of responsibility for each of the
                Parties in developing and deploying the solution and the types
                of skills and resources that are likely to be required.

        b.      It is intended that the Joint Solutions will be offered to the
                Customer under a single contract between a Party, who will act
                as the Prime, and the Customer. The Parties agree that all sales
                of ClickSoftware's Products shall be governed by ClickSoftware's
                standard license agreement.

        c.      Based on the Framework, the Project Office Leader and the
                Relationship Executive will jointly determine which Party will
                act as the Prime and which Party will act as the Sub. It is
                hereby agreed, that in most of the cases IBM will act as Prime.
                However, the Parties may agree that the Party which is expected
                to have the greatest level of responsibility in the deployment
                of the Joint Solution will be selected to function as the Prime
                unless (1) that Party is unable to make available to the Joint
                Solutions sufficient personnel with the requisite skills to act
                as the Prime or (2) a Customer requests that a particular Party
                be the Prime (it being understood that a Customer preference for
                a Prime may result in additional cost to that Customer). The
                Project Office Leader and the Relationship Executive shall use
                the following criteria to assist in determining which Party will
                act as Prime for each Joint Solutions:

                o       Stated Customer preference;
                o       The relative strength of each Parties' relationship with
                        the Customer;
                o       The level of value-added content or Core Competencies to
                        be provided by each Party; and
                o       Other factors that may be mutually agreed upon by the
                        Parties.


                                 Page 14 of 20
<PAGE>

        c.      The Project Office Leader and the Relationship Executive will
                select a team (the "Solutions Team") to develop the Joint
                Solution that will be submitted to the Customer. The Solutions
                Team will have one or more representatives from each Party's
                organization. If the Qualified Lead was provided to the Parties
                by a third party, and the Framework includes products or
                services to be provided by that third party, the Solutions Team
                may also include a representative from that third party. The
                Solutions Team will be responsible for developing the proposal
                and the proposal strategy for the Joint Solution and for
                overseeing the contracting process, all as more fully set forth
                below.

D.      DISPUTE RESOLUTION.

Both Parties will attempt in good faith to resolve all disputes or defaults by
mutual agreement before initiating any legal action or attempting to enforce any
rights or remedies hereunder. The Project Office Leader and the Relationship
Executive shall meet to discuss the resolution of the dispute or default. If
they are unable to do so within thirty (30) calendar days, the dispute shall be
escalated to the Management Council. If the Management Council is unable to
resolve the issue within fifteen (15) calendar days of the dispute having been
referred to it, the dispute shall be escalated to the Executive Sponsors. If
unresolved at the end of sixty (60) calendar days and after escalation to the
Executive Sponsors, either Party may pursue any rights or remedies as they may
have at law or in equity.

E.      EXPENSES

The Parties will be solely responsible for the expenses they individually incur
and both Parties will exercise reasonable efforts to minimize expenses
associated with meetings including, but not limited to, meeting via telephone,
personal computer conferencing, exchanging documents electronically, using
e-mail or fax machines and the like.

7.      TERM AND TERMINATION.

The term of this Agreement shall be ***17 from the Effective Date, subject to
early termination as specified in this Article. The occurrence of the First
Closing, as defined and as set forth in the Share Purchase Agreement, is a
condition to the entering into of this Agreement by the Parties.

A)      EARLY TERMINATION
Either Party may terminate this Agreement by giving the other Party not less
than 60 calendar days written notice prior to the anniversary date of the
Agreement, if such Party decides not to extend the activities of the Project
Office for an additional year. Such termination will take effect at the end of
the specific year during which notice is given. In such case, the Party to whom
notice is given agrees that it shall not have the right to claim damages from
the terminating Party in connection with this early termination. For avoidance
of doubt, in such case, the Parties agree that IBM will retain the payment of
***18 and the shares which had previously been issued to IBM.

<PAGE>

B)      TERMINATION FOR BREACH
Either Party may terminate this Agreement for material breach by the other Party
upon written notice containing the specific nature and dates of the material
breach. The breaching Party will have thirty (30) calendar days from receipt of
the notice to cure such breach. If such breach has not been timely cured, then
the non-breaching Party may immediately terminate this Agreement upon written
notice.
In the event of termination by IBM for material breach by ClickSoftware, the
Parties agree that IBM will retain the payment of ***19 and the shares which had
previously been issued to IBM and eventually claim damages in the event
ClickSoftware fails to issue to IBM the shares that were due to IBM prior to
termination.

8.      WARRANTY

Each Party represents and warrants to the other Party as to itself that the
execution, delivery and performance by it of this Agreement have been duly
authorized by all necessary corporate action on its part.

THE WARRANTIES IN THIS SECTION 8 ARE IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR
IMPLIED, INCLUDING WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF
NONINFRINGEMENT, NONINTERFERENCE, MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.

9.      LIMITATION OF LIABILITY

Circumstances may arise where, because of a default by a Party or other
liability, the other Party is entitled to recover damages from that defaulting
Party. In each such instance regardless of the basis on which such a claim is
based (including fundamental breach, negligence, misrepresentation, or other
contract or tort claim) a Party is liable for no more than ***20 (or a
particular country equivalent) per claim. This limit also applies to any of a
Party's subcontractors. It is the maximum for which a Party and its
subcontractors are collectively responsible. This limitation shall not apply to
the breach of the AECI, violation of the other Party's Intellectual Property
Rights, and to claims by a Party for bodily injury or damage to real property or
tangible personal property for which the other Party is legally liable.
