             Materials") shall not reflect adversely upon the good name of
             Tioga. OEM acknowledges that if the Marked Materials distributed by
             OEM were of inferior quality in design, material or workmanship,
             the substantial good will which Tioga has established and now
             possesses through the Tioga Marks would be impaired. Accordingly,
             OEM agrees that the Marked Materials shall be of high standard and
             of such nature, style, appearance and quality as shall be



                              Tioga Systems, Inc.

             adequate and suited to the protection of the Tioga Marks and the
             goodwill associated therewith.

     8.10.3  Upon Tioga's request, OEM shall provide to Tioga, free of cost, two
             samples of Marked Materials. Tioga, in Tioga's reasonable
             discretion, shall determine whether (i) the Marked Materials
             submitted by OEM comply with this Agreement, and (ii) such Marked
             Materials are of a high standard and of such nature, style,
             appearance and quality as to be adequate and suited to the
             protection and enhancement of the Tioga Marks and the goodwill
             associated therewith. If Tioga disapproves of any sample of the
             Marked Materials, Tioga shall provide OEM with the specific reasons
             for such disapproval.

             Materials.

     8.10.8  OEM shall not use the Tioga Marks, or any part thereof, as part of
             or in conjunction with any other names or trademarks except with
             Tioga's prior written approval. OEM shall not use the Tioga Marks
             or any confusingly similar or diluting mark, term or design, except
             as expressly authorized in this Agreement, and OEM shall not
             attempt to register or aid any third party in using or attempting
             to register any such mark, term or design. OEM shall not use any of
             the Tioga Marks in any manner that will indicate that it is using
             such mark other than as a licensee.

     8.10.9  Refusal to submit samples, or non-compliance with the provisions of
             Section 8.10 of this Agreement and/or the Tioga Trademark Usage
             Guidelines set forth in Exhibit B, will result in Tioga's right to
             revoke OEM's license to use the Tioga Marks.

             remain Tioga's exclusive property. OEM shall acquire no right,
             title or interest in the Tioga Marks or the goodwill associated
             therewith, other than the limited license and right to use the
             Tioga Marks set forth by the express terms of this Agreement. All
             usage of the Tioga Marks by OEM shall inure to Tioga's benefit. OEM
             shall not at any time do or suffer to be done any act which would
             impair the Tioga Marks or the goodwill associated therewith. OEM
             shall take any actions reasonable requested by Tioga, including the
             execution of instruments, that may be necessary or appropriate to
             register or otherwise confer or perfect Tioga's rights in the Tioga

             Section 8.10.

     8.10.12 OEM shall promptly notify Tioga in writing of any actual or

SECTION 12.  INDEMNIFICATION
             ---------------

     12.1.  By Tioga.  Tioga shall indemnify and hold harmless OEM against all
            --------
damages, costs, expenses, and liabilities (including reasonable attorneys' fees
and expenses) (collectively, "Damages") arising out of any claim of infringement
                              -------
of a  copyright or a patent claim or trademark or misappropriation of a trade
secret is asserted against OEM by a third party based upon OEM's exercise of its
rights in full compliance with this Agreement including OEM's use, in full
compliance with this Agreement, of Tioga's trademarks in the promotion or
marketing of the Products; provided, that, in each case, Tioga shall have (x)
received from OEM written notice of said claim as soon as practicable after the
assertion thereof, provided however that if there is a delay in providing such
notice that materially and adversely prejudices the defense of such claim Tioga
shall be released from the indemnification obligations set forth in this Section
12.1. ; (y) have received from OEM the exclusive right to control and direct the
investigation, defense, or settlement of such claims; and (z) received the
complete cooperation and assistance of OEM so long as Tioga reimburses OEM's
reasonable out-of-pocket expenses.  Tioga may not settle any such claim in a
manner that would restrict OEM's exercise of the rights granted to OEM hereunder
without OEM's written consent, which may not be unreasonably withheld.  In the
event Tioga reasonably believes that any Product infringes a third party
Intellectual Property right, Tioga may either:  (1) substitute for such Product
substantially similar programs and documentation, (2) procure for OEM the right
to continue using such Product or, if Tioga fails after commercially reasonable
efforts to accomplish options (1) and (2) above,(3) terminate this Agreement
upon thirty (30) days advance written notice and refund the license fees paid
for the Product that is the subject of the claim less depreciation as calculated
on a three-year straight-line basis commencing as of the Effective Date and
subject to the limitations set forth in Section 11 of this Agreement.  This
Section 12.1 sets forth OEM's sole and

<PAGE>

exclusive remedy with respect to any claim of Intellectual Property
infringement. The foregoing obligations of Tioga do not apply (A) with respect
to a Product which is modified after shipment by any party other than Tioga, if
the alleged infringement relates to such modification, if the unmodified Product
would not have given rise to the infringement, (B) with respect to Product that
was combined with any non-Tioga products, processes or materials where the
alleged infringement relates to such combination if the Product alone would not
have given rise to the infringement, (C) where the allegedly infringing activity
continues after Tioga has informed OEM of modifications that would have avoided
the alleged infringement and OEM has not complied with its obligations under
Section 3.3 of this Agreement or (D) with respect to infringement based on use
of a version other than the then current version (so long as OEM has had a
reasonable amount of time, not more than thirty (30) days to receive and
implement the then current version) of the Product if such infringement could
have been avoided by use of the then current version.

     12.2.  By OEM.  Without limiting Tioga's Intellectual Property
            ------

hold harmless Tioga against Damages arising out of (i) any third party claim
directly related to OEM's actions or omissions in its marketing, promotion,
advertising or sublicense of the Products and (ii) any claim of infringement of
a trademark asserted by a third party based upon Tioga's use, in full compliance
with this Agreement, of OEM's trademarks; provided, that, in each case OEM shall
have (x) received from Tioga notice of said claim as soon as practicable after
the assertion thereof, provided however that if there is a delay in providing
such notice that materially and adversely prejudices the defense of such claim
OEM shall be released from the indemnification obligations set forth in this
Section 12.2.  ; (y) have received from Tioga the exclusive right to control and
direct the investigation, defense, or settlement of such claims; and (z)
received complete cooperation and assistance of Tioga.

reasonable commercial efforts to repair, replace, advise or refund pursuant to

or in conjunction with hardware or software other than the unmodified version of
hardware and software with which the Software was designed to be used as
described in the Documentation.
