                              TERMS AND CONDITIONS

1.0 LICENSE

1.1 GRANT.

Corechange grants Client, a nonexclusive, nontransferable LICENSE to use the
Licensed Product identified on the Cover Page and known as Coreport (in object
code format only) and associated documentation (collectively, the "Licensed
Materials") in accordance with the terms and conditions of this Agreement. The
Licensed Materials are not being sold; rather all rights, title, and interest in
and to the Licensed Materials is retained by Corechange.

1.2 AUTHORIZED ACTIVITIES.

Client may: (a) install the software programs only on computer systems and in
locations within the United States and Canada; (b) use the Licensed Materials
exclusively for Client's own internal business use and benefit, for users in the
United States and Canada; and (c) make no more than one copy of the Licensed
Materials, and only for archival and back up purposes, provided that Client
properly reproduces copyright and other legal notices and restrictive legends of
ownership on each copy or partial copy. Client agrees to maintain records of
all copies.

1.3 PROHIBITED ACTIVITIES.

Client may not: (a) reverse assemble, reverse compile, disassemble or otherwise
attempt to access the source code of the software programs without the prior
written approval of Corechange (except in the European Economic Area or other
jurisdiction in which access is required for interoperability purposes, in which
case Client will promptly notify Corechange, and Corechange may, in its
discretion, perform such work at its consulting rate, or allow Client to access
the source code but only for the limited, required purpose); or (b) make the
Licensed Materials available to third party users, or sell, assign, sublicense,
rent, lease, lend or otherwise dispose of the Licensed Materials or transfer
this license to any other person, system or entity, except that Client may
assign its rights without consent of Corechange to a parent or wholly owned
subsidiary by providing prior written notice to Corechange.

2.0  SCOPE OF USE AND USE VERIFICATION

The Cover Page of this Agreement specifies the Licensed Materials that are being
licensed and defines the maximum number of users permitted under this Agreement.
Client may, at any time, increase the defined usage by providing Corechange with
prior written notice of the change. Additional license charges shall be subject
to mutual agreement by the parties, and adjustments shall be made to the fees
for Corechange Support as a result of an increase in the number of authorized
users. Corechange may reasonably request, at any time, configuration
documentation to verify the actual usage of the Licensed Materials. Corechange
may request from Client, but no more than twice annually, and Client agrees to
provide Corechange, a signed statement verifying the number of user accounts
administered by the Licensed Materials.

3.0 PROPRIETARY INFORMATION

Both Corechange and Client may make available to the other confidential and
proprietary materials and information ("Proprietary Information"). All material
and information provided by one party to the other relating to its business,
policies, procedures, customs, forms, customers and strategies, and identified
in writing as "confidential" or "proprietary", shall be considered to be
Proprietary Information. The pricing terms of this Agreement and the Licensed
Materials shall be deemed Proprietary Information of Corechange, whether or not
identified in writing as such. Proprietary Information does not include
information that: (i) is already, or otherwise becomes, generally known by third
parties as a result of no act or omission of the receiving party; (ii)
subsequent to disclosure hereunder is lawfully received from a third party
having the right to disseminate the information without restriction on
disclosure; (iii) is generally furnished to others by the disclosing party
without restriction on disclosure; (iv) was already known by the receiving party
prior to receiving them from the disclosing party and were not received from a
third party in breach of that third party's obligations of confidentiality; or
(v) is independently developed by the receiving party without the use of
Proprietary Information of the disclosing party. Each party shall maintain the
confidentiality of the other party's Proprietary Information and will not use or
disclose such Proprietary Information without the written consent of the other
party. Notwithstanding the foregoing, a party may disclose the Proprietary
Information of the other to its agents and other third parties on a need-to-know
basis, provided that such parties are under a similar obligation to maintain the
confidentiality of the Proprietary Information. Further, the parties may
disclose the other's Proprietary Information in a judicial or quasi-judicial
proceeding when required to do so by law when responding to a subpoena,
deposition notice or similar judicial or governmental demand; in such
situations, however, the party being requested to disclose the other's
Proprietary Information shall endeavor to provide notice to the other party
whereby the other party may intervene in the proceeding, if it wishes, and
endeavor to prevent such disclosure. Additionally, the parties may disclose the
other's Proprietary Information to their various regulatory agencies if
required, provided they take reasonable steps to limit further disclosure.
Notwithstanding any contrary provision of this Agreement, as long as each party
protects the Proprietary Information of the other, neither the exposure to the
other party's Proprietary Information, nor its ownership of work products, shall
prevent either party from using ideas, concepts, expressions, know-how, skills
and experience possessed by either party prior to its association with the other
party or developed by either party during its association with the other party,
so long as the Proprietary Information of the other party is not used. In case
of breach, the disclosing party shall have the right to seek injunctive relief.

4.0  LIMITED WARRANTY

4.1 SCOPE OF WARRANTY. Corechange warrants that it has the right to grant this
license authorizing the use of the Licensed Materials. Corechange warrants that
during the first one hundred twenty (120) days following delivery of the
Licensed Materials ("Warranty Period"), the Licensed Product will substantially
conform to the documentation provided with the Licensed Product, will not
include any virus, and will be free of intentionally disabling code (other than
standard security measures). Client's exclusive remedy for a breach of this
warranty shall be that Corechange will, at no additional charge, correct or
replace any material part of the Licensed Product that is or becomes defective,
provided that Corechange receives written notice of the defect during the
Warranty Period. If Corechange is unable to correct or replace the Licensed
Product, Corechange can terminate the Agreement, and return any license fees
paid for the Licensed Materials, with no additional liability by Corechange to
Client. After the Warranty Period, correction will only be available through
continued enrollment in Corechange Support as set out in Section 5. Corechange
specifically waives responsibility for any third party product or service that
may be used by Client in conjunction with the Licensed Materials.

4.2 ACKNOWLEDGMENTS. Unless otherwise agreed by Corechange and Client, Client
acknowledges that it shall be solely responsible for (i) providing the proper
operating environment for the Licensed Materials; (ii) installing the Licensed
Materials; (iii) training end users; (iv) establishing proper back-up
procedures; (v) portal layout and look-and-feeling planning; and (vi) user,
role, content (internal and external) definition and gathering.

4.3 EXCEPTIONS. The obligations of Corechange under Section 4.1 shall not apply
to the extent Client: (i) modified the Licensed Materials, (ii) did not follow
the instructions that Corechange provided, (iii) used the Licensed Materials in
an unauthorized manner in combination with other non-Corechange products and the
claims resulted from that combination, or (iv) is not currently enrolled in
Corechange Support.

4.4 DISCLAIMER. EXCEPT FOR THE EXPRESS WARRANTIES IN SECTION 4.1, CORECHANGE
DISCLAIMS ALL OTHER WARRANTIES AND/OR REPRESENTATIONS, EXPRESS OR IMPLIED,
WRITTEN OR VERBAL, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

5.0  CORECHANGE SUPPORT

5.1 OVERVIEW. Corechange will offer those support services ("Corechange
Support") set out in the attached Support Schedule. In addition to the support
services therein, new versions of the Licensed Materials may be made available
on a discounted basis through Corechange Support. Corechange may, however,
develop and market new products containing new functionality, which may include
portions of previously licensed products, and such new products may not be made
available through Corechange Support.

5.2 ANNUAL RENEWALS AND ADJUSTMENTS. Corechange Support will be provided at no
additional charge for thirty (30) days after the Effective Date. Enrollment in
Corechange Support will begin thirty (30) days after the Effective Date.
Corechange Support may be renewed each year on the anniversary of the beginning
of enrollment in Corechange Support. Corechange will provide Client an invoice
for such renewal, and Client will pay within 30 days from invoice but shall not
be required to pay earlier than 30 days before the anniversary date. Client
shall be automatically renewed effective the anniversary date unless Client
provides written notice of cancellation within thirty (30) days from the date of
invoice. Corechange will make Corechange Support available to Client for as long
as Corechange provides Corechange Support to other clients for the Licensed
Product, and in no event less than three (3) years. Client may elect to prepay
annual support fees at current rates or contractually commit to continue
enrollment for a defined number of renewal periods. Corechange may adjust the
annual fee (or any portion thereof) during the enrollment period to reflect
usage upgrades that may occur during the enrollment period or to reflect
increased costs of providing Corechange Support. Notwithstanding the previous
sentence, the support fees charged to Client for the number of users licensed
hereunder shall not be increased by more that 7% compounded per annum, although
additional charges may be made to reflect an increased number of users. No
refunds or credits will be given for Client's early termination of Corechange
Support.

5.3 REINSTATEMENT. If at any time after enrollment, Corechange Support is
terminated, Client may elect to reinstate Corechange Support by paying the then
current annual fee for Corechange Support plus a reinstatement fee based on the
cost for Corechange Support during the period when Corechange Support was
terminated.

6.0  PAYMENT

Payment of all fees specified in an invoice and not the subject of a good faith
dispute is payable upon receipt. In case of a good faith dispute, Client will
provide the reasons for such dispute within 15 days of invoice, will pay all
undisputed amounts, and will work diligently with Corechange to resolve the
dispute. Client acknowledges that the Licensed Materials have been delivered to
Client pursuant to the terms of this Agreement, and Client expressly accepts
delivery of such license, and agrees to be bound by the payment terms of this
contract. Invoices for Corechange Support will be issued up to ninety (90) days
prior to the renewal date. Under certain licensing options, additional license
fees may come due as a result of changes to usage, the operating environment or
system configuration, or upgrade for which a charge is made. Corechange will
issue an invoice upon (i) receipt of Client's written notice specifying this
change/upgrade. Client also agrees to pay all amounts equal to any applicable
taxes (e.g. sales, use, personal property, etc.) resulting from any transaction
under this Agreement, not including any taxes based on Corechange's net income
or employment taxes. Invoices remaining unpaid for thirty (30)

and one-half percent (1.5%) per month (or such lesser amount if required by law)

7.0  LIMITATION OF LIABILITY

Except to the extent agreed otherwise, Client is responsible for the proper
installation and operation of the software programs including, without
limitation, confirming the proper configuration of its computer system(s). In
the event a problem arises with the Licensed Materials, Client agrees that

direct actual damage. Except for Corechange's obligations to indemnify for third

DAMAGE OR LOSS.

8.0  TERMINATION

8.1 EARLY TERMINATION. Either party may terminate in event of a material breach
that remains uncured after thirty (30) days from receipt of written notice, or
ten (10) days in case of breach of Section 1.3, 3, or 6.

8.2 EFFECT OF TERMINATION. Upon termination except by Client due to an uncured
material breach by Corechange, Client agrees to immediately delete all copies of
the software programs that are installed on its computer systems and return to
Corechange all documentation and tangible embodiments of the Licensed Materials,
together with a written statement certifying completion of these obligations.
The provisions of Sections 1.2, 3, 4.4, and 7-9, and 11, shall survive any
termination, as shall any other section to the extant it survives by its own
terms. Termination shall not extinguish any amount owed to Corechange hereunder
that accrued prior to termination. In case of termination by Client due to an
uncured material breach by Corechange, Client shall be entitled to a refund of
prepaid amounts for Corechange Support not provided, and shall be entitled to
continue its license under Section 1.1, provided that the limitations of
Sections 1.2, 1.3, 2, 3, 4.4, and 7 shall survive such termination.

claim that the Licensed Materials or Client's use or possession of the Licensed
Materials infringes a patent, copyright, trade secret, or other intellectual
property right of a third party, Corechange shall defend such claim or action at
its expense and shall pay all costs, attorney's fees, damages, settlements and
other amounts awarded or agreed to in connection with any such claim or action,

reasonable assistance, and (z) control of the claim to Corechange. Corechange
shall have no obligation to indemnify to the extent the claim arises from (i)
the use of the Licensed Materials with other products not provided by
Corechange; or (ii) any unauthorized uses of or modifications to the Licensed
Materials. If Client is enjoined, precluded, or advised by Corechange to refrain
from using the Licensed Materials because of any such infringement or any
infringement claim or allegation, Corechange shall, and at Corechange's expense
and option: (a) procure for Client the right to continue using the Licensed
Materials; (b) replace or modify the Licensed Materials so that they becomes
non-infringing without materially and adversely affecting the performance of the
Licensed Materials or significantly lessening the utility of the Licensed
Materials to Client; or (c) if either of the above two options are not available
on commercially reasonable terms, accept return of the Licensed Materials at

three (3) year straight-line amortization. This provision states the sole and
exclusive liability of Corechange for infringement or breach of third party
rights.

                                       4
<PAGE>

provisions of this Agreement, it shall not thereby be deemed to have waived any
preceding or succeeding breach of the same or any other provisions herein. This
Agreement shall be governed by and construed in accordance with the laws of the
State of New York, without regard to its choice of law provisions. A copy of any
notice of breach of the terms of the Agreement shall be forwarded to: ABN AMRO
