                              TERMS AND CONDITIONS

1.0 LICENSE

1.1 GRANT.

Corechange grants Client, a nonexclusive, nontransferable LICENSE to use the
software programs known as Coreport (in object code format only), associated
documentation, and the software programs and documentation provided as a result
of the professional services ("Deliverables") (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 the authorized computer
systems(s) and locations, as defined by this Agreement, within the United States
and Canada; (b) use the Licensed Materials exclusively for Client's own internal
business use and benefit (including for the benefit of all majority owned
subsidiaries); and (c) make no more than one copy of the Licensed Materials 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, unless such access is required by applicable
law, in which case 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) sell, assign, sublicense, rent, lease, lend or
otherwise dispose of the Licensed Materials or transfer this license to any
other person, system or entity, including, without restriction, other Client
locations, service providers or facilities managers, except that Client may
assign without consent to a parent or wholly owned subsidiary by providing prior
written notice to Corechange.

2.0  SCOPE OF USE AND USE VERIFICATION

The front page of this Agreement specifies the Licensed Materials that are being
licensed and also defines the maximum installation and usage 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
as well as adjustments to the fees for Corechange Support may be incurred as a
result of this usage change. 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 SERVICES

Corechange, its employees. agents and/or contractors shall provide the
professional services stated in Attachment A to this Agreement. Corechange
agrees to perform the services with care, skill and diligence in accordance with
applicable professional standards. Client agrees to fully cooperate with
Corechange and provide all assistance reasonably necessary for Corechange to
provide the required services. In the event that Corechange experiences delays
resulting from Client's failure to provide the necessary assistance including,
without limitation, the proper desktop and application operating environments
and personnel, Corechange may be required to bill Client an additional per diem
charge at its standard consulting rate.

4.0 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 Licensed Materials shall be deemed Proprietary Information
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


                                       2
<PAGE>

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.
