         1.3. "Xcare.net Software" shall mean all computer program code and
other results and proceeds of Xcare.net's services hereunder (other than
Content) that are delivered by Xcare.net to Client pursuant to this Agreement.
Such Xcare.net Software shall be provided in object code form unless the parties
mutually agree in writing to delivery of source code.

         1.4. "Client Web Site(s)" shall mean the so-called "web page" site or

Schedule for new services shall be successively numbered (e.g., 1, 2, etc.).
Each schedule shall be executed by the parties and shall be subject to the terms
and conditions of this Agreement. Xcare.net shall provide qualified and trained
personnel to render such services and shall use reasonable commercial efforts to
meet the delivery schedule set forth in the applicable Schedules. Any additions,
deletions or other changes to a Schedule shall be mutually agreed to in writing
in advance by both parties and shall be memorialized in a revised Schedule
pursuant to the procedure set forth in Section 2.6 below for Change Orders. All
services shall be performed at Xcare.net's offices unless otherwise agreed by
the parties. In the event that services are performed at Client's location,
Client shall provide Xcare.net at no charge with all necessary facilities and
equipment, including without limitation, computer time on Client's computers and
office space, sufficient to render the services contemplated hereunder. Client
shall deliver to Xcare.net all Content selected by Client for incorporation into

set forth in the applicable Schedule(s). In the event that Client fails to
deliver the Content in accordance with the delivery schedule, the development
schedule shall be extended by the number of days that delivery of the Content
was delayed, unless Xcare.net notifies Client that this extension will not
rectify Xcare.net's scheduling interruption resulting from Client's delay and
such delay may also result in additional charges to Client, in which case the
parties shall mutually agree upon a new delivery schedule and fees with respect
to the rendition of the Development Services.

deliverable if Xcare.net does not receive written notice of Client's objections
within said fifteen (15) day period.

services are included in the Schedule, Xcare.net shall use commercially

selected by Client. Client will be solely responsible for all out-of-pocket

Agreement. Further, Xcare and Client agree to allow reasonable, non-material

6. INTELLECTUAL PROPERTY INDEMNIFICATION

         6.1. Xcare.net.

               6.1.1. Indemnification. Xcare.net, at its own cost and expense,
shall defend Client and its officers and directors, against a claim that the

secret, and shall pay any settlements entered into or damages awarded against
Client, or its officers and directors, to the extent related to such claim,
provided that (i) Client notifies Xcare.net promptly in writing of the claim;
(ii) Xcare.net has the sole control of the defense and all related settlement
negotiations; and (iii) Client provides Xcare.net with all reasonably necessary
assistance, information, and authority to perform the foregoing at Xcare.net's

               6.1.2. Xcare.net shall have no liability for any claim of
infringement based on (i) use by Client of other than the current update of the
Xcare.net Software if the infringement would have been avoided by uses of the
current update; (ii) modifications, adaptations or changes to the Xcare.net
Software not made by Xcare.net; (iii) the combination or use of the materials
furnished hereunder with materials not furnished by Xcare.net if such
infringement would have been avoided by use of the Xcare.net materials alone; or
(iv) use or incorporation of Content or Modified Content. In the event the
Xcare.net Software is held to, or Xcare.net believes is likely to be held to,
infringe the intellectual property rights of a third party, Xcare.net shall have

Xcare.net Software

                                       6

so that it is non-infringing and qualitatively and functionally equivalent to
the Xcare.net Software; (ii) obtain for Client a license to continue using the
Xcare.net Software; or if neither (i) nor (ii) is commercially reasonable,
Xcare.net shall have the right to terminate this Agreement immediately upon
written notice to Client, and Xcare.net shall make payment to Client of an
amount equal to the fees paid for the Xcare.net Software, pro-rated over a three
(3) year period commencing on the Effective Date. This Section 6.1 sets forth
Client's sole and exclusive remedy and Xcare.net's sole liability for
intellectual property infringement by Xcare.net.

         6.2. Client.

               6.2.1. Client hereby represents and warrants to Xcare.net that
(i) Client has secured all necessary consents, permissions, clearances,
authorizations and waivers for the use of Content or Modified Content, including
without limitation, all text, pictures, audio, video, logos and copy contained
in all Content or Modified Content; (ii) the use of Content as contemplated
herein shall not infringe the copyright, trademark or other intellectual
property rights of any party, or constitute defamation, invasion of privacy,
or the violation of any right of publicity or any other right of any party;
and (iii) Client has complied and shall comply with all legislation, rules and
regulations regarding Content.

               6.2.2. Client shall indemnify and hold harmless Xcare.net, its
directors, officers, parent company, and affiliates, from any and all liability,
costs and expenses (including attorney's fees) arising in connection with any

officers, parent company, and affiliates, relating to Content or Modified
Content, provided (i) Xcare.net notifies Client promptly in writing of such
claim, (ii) Client has the sole control of the defense and all related
settlement negotiations, and (iii) Xcare.net provides Client with all reasonably
necessary assistance, information and authority to perform the foregoing at

default; (ii) the commencement of a voluntary case or other proceeding seeking

other similar official of it or any substantial part of its property; (iii)
either party's consent to any such relief or to the appointment of or taking
possession by any such official in an involuntary case or other proceeding
commenced against it; or (iv) either party's making a general assignment for
the benefit of creditors; or either party's becoming insolvent; or either party
taking any corporate action to authorize any of the foregoing.

4.4  In the event of termination by Client for any reason other than expiration
of a service order or a service interruption as defined in subsection 4.2,
Client agrees to immediately pay Xcare.net as a cancellation fee all monthly
recurring fees specified in the quote provided by Xcare.net for such service
order for the balance of the then current term, not to exceed the monthly fee.

is sought and then only to the extent expressly specified therein.

                                                                               4
