receivership or reorganization proceeding or is placed in a trusteeship
involving an insolvency, or ceases doing business in the ordinary course, this
Agreement automatically shall terminate.

          7.2.3  Additional Termination Rights.  Engage may elect to terminate
                 -----------------------------

9.   Indemnification.
     ---------------

     9.1  Indemnification of Provider.  Engage shall, at its expense, indemnify,
          ---------------------------
hold harmless and defend Provider from and against any and all damages, costs
and expenses, including reasonable attorneys' fees, incurred by Provider in
connection with a claim that the Technology, as delivered by Engage and used by
Provider within the scope of this Agreement, infringes any copyright, provided
that Provider notifies Engage promptly in writing of the infringement claim and
Engage has sole control over the defense or settlement of such claim and
Provider, at its expense, provides reasonable assistance in the defense of the
same.  Notwithstanding the foregoing, in the event that an infringement is found
and continued use of the Technology is enjoined, Engage will, at its option and
expense, either:  (i) procure for Provider the right to continue to use the
Technology; (ii) modify or alter the Technology so that it becomes non-
infringing; or (iii) replace the Technology with a non-infringing alternative.
If all of these options may only be exercised by Engage at an unreasonable cost,
then Engage may require Provider to immediately cease all use and distribution
of the Technology and terminate the Subscription Agreements under this Agreement
and pay to the Provider the Technology purchase fees that Provider paid to
Engage, less a portion for prior usage, amortized over a 3 year period.

     Engage shall have no obligation to indemnify Provider with respect to any
claim based upon (i) any modification of the Technology by a party other than
Engage; (ii) the combination, operation or use of the Technology with a non-
Engage software program or data if the claim would have been avoided had such
combination, operation or use not occurred; or (iii) the use of other than the
latest release of the Technology, if such claim could have been avoided by use
of the latest unmodified release.  Engage's obligation to indemnify Provider
will be reduced to the extent the damages could have been reduced by Provider's
use of the latest release.

     9.2  Indemnification of Engage.  Provider shall, at its expense, indemnify,
          -------------------------
hold harmless and defend Engage from, and against any and all damages, costs and
expenses including reasonable attorneys' fees, incurred by Engage in connection
with

                                       11
<PAGE>

any claim (i) against Engage by any Subscriber which relates to such
Subscriber's relationship with Provider or a subdistributor (and not to any
direct relationship which Engage may have with such Subscriber), (ii) arising
from the performance of the Data Services by Provider, or (iii) any
representation, promise, guarantee or warranty made or implied by Provider or a
subdistributor to the extent it exceeds or differs from those expressly set
forth in the documentation accompanying the Data Services EXCEPT as may be
attributed to Engage's failure to meet the representations, warranties,
covenants or other agreements herein or in the Shareholders Agreement:

10.  Warranty and Disclaimer.
     -----------------------

     10.1  Warranty of Authority.  Engage represents and warrants that it
           ---------------------
possesses the rights in the Know How to perform its obligations hereunder.  The
representations and warranties contained in Clauses 22.2 and 22.4 of the
Shareholders Agreement shall apply in relation to the Technology as if they were
set forth in full herein for the benefit of Provider.

     10.2  DISCLAIMER OF WARRANTIES.  EXCEPT AS SET FORTH HEREIN OR IN THE
           ------------------------
SHAREHOLDERS AGREEMENT, ENGAGE MAKES NO WARRANTIES OR REPRESENTATIONS TO

RENDERED WITH THE TECHNOLOGY OR SOFTWARE.  ENGAGE DISCLAIMS ALL EXPRESS AND
IMPLIED WARRANTIES, ORAL OR WRITTEN, INCLUDING BUT NOT LIMITED TO, IMPLIED
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT
AND ANY WARRANTIES ARISING FROM COURSE OF DEALING, COURSE OF PERFORMANCE OR
USAGE OF THE TRADE.

     10.3  Acknowledgment.  Provider acknowledges that the Know How and
           --------------
Technology have not been prepared to meet the individual requirements of
Provider or its Subscribers.  It is the responsibility of Provider and its
Subscribers to ensure that the functions and facilities performed by the
Technology and Data Services meet the Subscriber's requirements.

11.  Limitation of Liability.
     -----------------------

     NOTWITHSTANDING ANYTHING ELSE IN THIS AGREEMENT OR OTHERWISE, NEITHER
ENGAGE NOR ITS AFFILIATES SHALL BE LIABLE OR OBLIGATED WITH RESPECT TO THE
SUBJECT MATTER OF THIS AGREEMENT OR UNDER ANY CONTRACT, NEGLIGENCE, STRICT
LIABILITY OR OTHER LEGAL OR EQUITABLE THEORY (I) FOR ANY AMOUNTS IN EXCESS IN
THE AGGREGATE OF THE FEES PAID TO IT HEREUNDER; OR (II) SPECIAL, CONSEQUENTIAL,
INCIDENTAL, RELIANCE, EXEMPLARY, OR INDIRECT DAMAGES (INCLUDING SUCH DAMAGES DUE

waiver of any breach of this Agreement shall constitute a waiver of any
subsequent breach of the same or any other provision of this Agreement.

           -------
writing sent prepaid by certified or registered mail or overnight express

arbitration shall be held in Tokyo, Japan. In the event that the arbitration is

U.S.A. The arbitration shall be in the English language. Notwithstanding the
foregoing, each party shall have the right to institute judicial proceedings
against the other party or anyone acting by, through or under such other party
in order to enforce the instituting party's rights hereunder through reformation

          ----------------------------
Fee discount set forth on Attachment 1, Contributor will deliver to Engage the
                          ------------
Visitor Data from each Domain Name.  The Software automatically will deliver the
Visitor Data from Contributor to Engage.

     4.2  Engage Use of Visitor Data.  Engage will not (i) collect or store
          --------------------------
Personal Information, (ii) sell, report or transfer unprocessed Visitor Data
from Contributor to any third party, or (iii) aggregate or present Visitor Data
from Contributor in a form or manner that would permit a third party to (a)
identify any individual's Personal Information or identity, (b) identify the
data as originating from Contributor or (c) associate an individual with a
Profile.

          -------------------
permitting Contributor to map Visitor Data to predefined demographic and other
categories ("Classification File").  Contributor will actively maintain and
manage the Classification File in cooperation with Engage so that the
Classification File is accurate and comprehensive in its mapping of Visitor
Data.  In the event that Engage reasonably believes that Contributor is failing
to meet the foregoing standard, Engage will notify Contributor or such failure
and, unless Contributor cures the failure within 30 days from such notification,
Engage may either cancel the Subscription Fee discount for contribution of
Visitor Data or terminate this Agreement.

5.   PRIVACY POLICY

     Licensee, whether a Subscriber or Contributor or both under this Agreement,

<PAGE>

license to install and operate only on Licensee's premises in the U.S. the
Software solely for Licensee's own internal use on one or more Enterprise or
Local Servers hosting the Domain Name(s).

     6.2  Restrictions.  Licensee may use the Software only for the purpose of
          ------------
subscribing and/or contributing to the Data Repository.  Without limiting the
foregoing, Licensee may not use the Software for the purpose of creating,
maintaining or operating an enterprise or any other data repository.  Except as
expressly provided herein, Licensee shall not, and shall not permit others to,
use, modify, copy (except for one Licensee back-up copy containing Engage's
copyright notices and other proprietary marks), distribute, sublicense, assign,
use for service bureau purposes, share, timeshare, rent or otherwise transfer,
or decompile, disassemble, reverse engineer or otherwise attempt to derive the
source code form of the Software, in whole or in part.  All rights not expressly
granted to Licensee are reserved by Engage.  There are no implied rights.

     6.3  Indemnification.  Engage, at its expense, shall defend any action,
          ---------------
suit or proceeding brought against Licensee which alleges that the Software
infringes any U.S. copyright and Engage shall pay damages finally awarded
against Licensee; provided that Licensee promptly notifies Engage of the action
and gives Engage the opportunity, sole authority, information and assistance (at
Engage's expense) for control of the defense and settlement of the action; but
Engage shall not be responsible for any legal costs incurred or settlement made
without notice and its consent.  Engage may, at its sole option and at its
expense, either:  (i) replace or modify the Software to make it non-infringing
without material impairment of its functionality; (ii) obtain for Licensee the
right to continue using the Software, or (iii) terminate this Agreement.  Engage
shall have no liability for any infringement or claim thereof based upon:  (a)
the combination of the Software with products not provided by Engage, or (b)
modification or alteration of the Software by any person or entity other than
Engage.  THIS SECTION STATES ENGAGE'S SOLE LIABILITY WITH RESPECT TO
INFRINGEMENT OF ANY INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS.

     6.4  Maintenance Services.  Subject to the terms and conditions of this
          --------------------
Agreement, Engage will provide Licensee with the Software maintenance services
set forth in Attachment 1 during the term of this Agreement.
             ------------

7.   PROPRIETARY RIGHTS AND CONFIDENTIALITY

     7.1  Proprietary Rights.  As between Engage and Licensee, Engage will own
          ------------------
all right, title and interest in and to the Profiles, Data, Visitor Data, Data
Repository and Software, as well as all intellectual property and proprietary
rights therein.

                                       20
<PAGE>

     7.2  Visitor Data.  Contributor hereby assigns, and agrees to assign in the
          ------------
future, to Engage and its successors and assigns, all right, title and interest
in and to the Visitor Data, as well as all intellectual property rights therein.
From time to time upon the request of Engage or its successor or assign,
Contributor will make such further assignments and confirm such assignments by
execution and delivery of such assignments, confirmations of assignment, or
other written instruments as Engage may reasonably request in order to
effectuate this Section 7.2.

     7.3  Confidentiality.  Licensee acknowledges and agrees that (i) the Data,
          ---------------
Profiles, Documentation and the design, operational methods and coding of the
Software (collectively "Confidential Materials") are not generally known to, or
readily ascertainable by, the public, (ii) Engage uses all reasonable efforts on
a consistent basis to prevent the acquisition, disclosure or use of the
Confidential Materials without the specific consent of Engage, (iii) Engage
derives substantial economic value from the secrecy of the Confidential
Materials, and (iv) acquisition, disclosure or use, beyond the limited extent
permitted herein, of the Confidential Materials would cause significant damage
to Engage's business.  Accordingly, Licensee agrees to hold the Confidential
Materials in strict confidence and not to disclose the Confidential Materials to
any third party without the prior consent of Engage.

     7.4  Equitable Relief.  Licensee acknowledges that the unauthorized
          ----------------
disclosure or use of the Confidential Materials other than as expressly set
forth herein will (i) substantially diminish the value to Engage of the
Confidential Materials and (ii) cause irreparable injury in a short period of
time, and that Engage's remedy at law for such unauthorized disclosure or use is
inadequate.  Accordingly, if Licensee breaches any of its obligations with
respect to the confidentiality or use of the Confidential Materials, Engage will
be entitled to equitable relief to protect its interests therein, including, but
not limited to, preliminary and permanent injunctive relief, in addition to any
other remedies it may have, without the necessity of posting bond.

8.   LIMITED WARRANTY

     8.1  Data.  Engage will use commercially reasonable efforts to promptly
          ----
serve to Subscriber Profiles matching Subscriber requests.

     8.2  Software.  Engage warrants that the Software, if operated on the
          --------
Specified Configuration will function in material conformity with the related
Documentation for a period of ninety (90) days from shipment (the "Warranty
Period").  Receipt by Engage of a written claim under this limited warranty must
occur within such period as a condition of this limited warranty.  Engage does
not warrant that the Software will be error free or that all errors and defects
can or will be remedied.  Engage's entire liability and Licensee s exclusive
remedy under this warranty shall be for Engage to make commercially reasonable
efforts to remedy in a

                                       21
<PAGE>

commercially reasonable manner any material nonconformance reported by Licensee
in writing within the Warranty Period, which obligation may be discharged by
modifying erroneous Documentation.

     8.3  LIMITATION.  THE LIMITED WARRANTY STATED IN THIS SECTION 8 AND THE
          ----------
REMEDIES SET FORTH HEREIN ARE EXCLUSIVE AND IN LIEU OF ALL OTHERS WITH RESPECT
TO THE PROFILES, DATA, VISITOR DATA, DATA REPOSITORY AND SOFTWARE, AND ENGAGE
AND ITS LICENSORS HEREBY DISCLAIM ALL OTHER WARRANTIES, REPRESENTATIONS, AND
CONDITIONS, ORAL OR WRITTEN, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING
WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
