     2.4  Reseller's Duties.
          -----------------

          2.4.1  Marketing Efforts. Reseller shall use its best efforts to

Engage shall have no obligation under this Agreement to provide Reseller or
its End Users any maintenance or support services.  Reseller may elect to

maintenance services agreement (the "Maintenance Services Agreement"); in such
event, Engage shall be responsible for providing such services only to Reseller
pursuant to the terms and conditions of such agreement.  For avoidance of doubt,

set out in Section 11.1 (such Errors and failures are defined herein as
"Warranty Defects").  Reseller shall use its commercially reasonable best
efforts to resolve with End Users all user and operational errors. If problems
are attributable to defective media, Engage shall, as soon as practicable,
supply replacement Products at no cost to Reseller.  If Reseller believes that
user problems are due to Warranty Defects, it shall promptly report this fact to
Engage and Engage shall make its best endeavors to remedy such Warranty Defects
pursuant to Section 2.5.2 and Section 11.1.

expiration or nonrenewal of this Agreement for indemnification, compensation,
reimbursement, or damages for loss of prospective compensation, goodwill or loss
thereof, or expenditures,

                                       10

investments, leases, or any type of commitment made in connection with the
business of such party or in reliance on the existence of this Agreement
including, but not limited to advertising and promotion costs, costs of

10.  Indemnification.
     ---------------

     10.1  Indemnification of Reseller.  Engage shall, at its expense,
           ---------------------------
indemnify, hold harmless and defend Reseller from and against any and all
damages, costs and expenses, including reasonable attorneys' fees, incurred by
Reseller in connection with (a) a claim that a Product, as delivered by Engage
and used by Reseller within the scope of this Agreement, infringes any
copyright, (b) a prohibition or restriction on Reseller's exercise of any right
granted in Section 2 hereof during the term of this Agreement other than those
prohibitions or restrictions set forth in this Agreement (or any other agreement
between the parties); provided that Reseller notifies Engage promptly in writing
of the infringement claim and Engage has sole control over the defense or
settlement of such claim and Reseller, 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 a Product is enjoined,
Engage will, at its option and expense, either: (i) procure for Reseller the
right to continue to use the Product; (ii) modify or alter the Product so that
it becomes non-infringing; or (iii) replace the Product with a non-infringing
alternative. If all of these options may only be exercised by Engage at an
unreasonable cost, then Engage may require Reseller to immediately cease all use
and distribution of the Product and terminate the End User Licenses granted
under this Agreement and pay to the Reseller the Product purchase fees that
Reseller paid to Engage, less a portion for prior usage, amortized over a 3 year
period.

     Engage shall have no obligation to indemnify Reseller with respect to any
claim based upon (i) any modification of a Product by a party other than Engage;
(ii) the combination, operation or use of the Product 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 a Product, if such claim could have been avoided by use of the latest
unmodified release, which release is provided by Engage to Reseller pursuant to
the terms of the Maintenance Services Agreement.  Engage's obligation to
indemnify Reseller will be reduced to the extent the damages could have been
reduced by Reseller's use of the latest release.

     10.2  Indemnification of Engage.  Reseller 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 any claim (i) against Engage by an End User which
relates to such End User's relationship with Reseller or a subdistributor (and
not to any direct relationship which Engage may have with such End User), (ii)
described in clauses (i) through (iii) of Section 10.1 above, (iii)

                                       11
<PAGE>

arising from the performance of a Product or maintenance and support services
rendered or required to be rendered in connection with the distribution of a
Product to an End User, except, if Reseller has purchased maintenance and
support services from Engage, as may be attributed to Engage's failure to render
such maintenance and support services to Reseller, or (iv) any representation,
promise, guarantee or warranty made or implied by Reseller or a subdistributor
to the extent it exceeds or differs from those expressly set forth in the
documentation accompapying a Product, EXCEPT as may be attributed to Engage's
failure to meet the representations, warranties, covenants or other agreements
herein or in the Shareholders Agreement.

     10.3  Use of Engage Name.  The rights and obligations contained in Section
           ------------------
12 of the Shareholders Agreement shall apply in relation to the Products as if
they were set forth in full herein for the benefit of Reseller.

11.  Warranty and Disclaimer.
     -----------------------

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

     11.2  DISCLAIMER OF WARRANTIES.  OTHER THAN THE WARRANTIES MADE TO RESELLER
           ------------------------
CONTAINED OR REFERENCED HEREIN, ENGAGE MAKES NO WARRANTIES OR REPRESENTATIONS AS
TO ANY PRODUCT OR AS TO ANY SERVICES RENDERED TO RESELLER OR ANY OTHER PERSON.
ENGAGE RESERVES THE RIGHT TO CHANGE ITS PRODUCT WARRANTY AND SERVICE POLICIES AT
ANY TIME, WITHOUT FURTHER NOTICE AND WITHOUT FURTHER LIABILITY TO RESELLER OR
ANY OTHER PERSON SUBJECT TO THE CONSENT OF RESELLER WHICH CONSENT WILL NOT BE

           ---------------
