and authority to grant the license of the OAOHS Software and other rights
granted by this Agreement to Customer with respect to the Software without the
consent of any other person; and that neither the performance of services by
OAOHS, nor the license of and use by Customer of the OAOHS Software as described
herein will in any way constitute an infringement or other violation of any
copyright, trade secret, trademark, patent, invention, proprietary information,
non-disclosure or other rights of any third party.

     7.2. Software Warranty. OAOHS will warrant the OAOHS Software so long as
Customer maintains an enforceable Software Support and Maintenance Addendum.
OAOHS warrants that the OAOHS Software will operate as described in the OAOHS
Documentation. If the OAOHS Software fails to so perform, Customer shall
immediately notify OAOHS to that effect in writing, describing such failure to
operate in reasonable detail. Upon receipt of such notice, OAOHS' sole
obligation shall be to conform the OAOHS Software to the Documentation, or to
replace the OAOHS Software with conforming Software. Such warranties do not
apply to any Third Party Products or modification made by Customer or others or
to any noncompliance resulting from use or combination of the OAOHS Software
with any products, goods, services or other items furnished by anyone other than
OAOHS. OAOHS does not warrant that the OAOHS Software and User Manuals are free
from all bugs, errors and omissions.

     7.3. Customer Warranties. Customer warrants to OAOHS that it has such

Customer warrants that it will not us the System for any illegal purpose.

     7.4. No Virus Warranty. OAOHS represents and warrants that it will follow
reasonable security customs, procedures and standards of the industry to avoid

     8. Indemnification by OAOHS. Subject to the limitations of liability
contained in the Master Terms and Conditions, if a claim is made or an action
brought for infringement of a U.S. patent, or any copyright, trademark, trade
secret or other proprietary right against Customer related to any OAOHS Software
provided by OAOHS under this Agreement, OAOHS will defend Customer against such
claim and will pay resulting costs and damages finally awarded, and attorney's
fees, provided that (i) Customer promptly notifies OAOHS in writing of the
claim, (ii) OAOHS has sole control of the defense and all related settlement
negotiations, and (iii) Customer cooperates in such defense at no expense to
Customer. The obligations of OAOHS under this Section are conditioned on
Customer's agreement that if the OAOHS Software, or the use or operation
thereof, becomes, or in the opinion of OAOHS is likely to become, the subject of
such a claim, OAOHS may at its expense either procure the right for Customer to
continue using the Software or, at the option of OAOHS, replace or modify the
same so that it becomes


                                                                              15
<PAGE>
non-infringing (provided such replacement or modification does not adversely
affect Customer's use of the OAOHS owned Software as contemplated hereunder). If
neither of the alternatives is available on terms which are reasonable in OAOHS'
judgment, Customer will return the Software on written request by OAOHS and
OAOHS will credit or refund to Customer, at Customer's option, the price paid
for such OAOHS owned Software less depreciation on a straight line basis over an
assumed seven year service life. If OAOHS gives Customer notice that it chooses
not to defend such claim or attempt to settle such claim on reasonable terms,
OAOHS shall be deemed to have elected not to conduct the defense of the subject
claim, and in such event Customer shall have the right to conduct defense and to
compromise and settle the claim without prior consent of OAOHS, and in such
case, the indemnity set forth in the first sentence of this paragraph shall
apply, provided that Customer's right to defend or settle the claim and OAOHS'
above indemnity shall be contingent upon Customer's compliance with the sentence
immediately preceding this sentence.

     9. Effect of Termination. Immediately upon termination of the Agreement,
Customer shall immediately: (i) cease using all Software and Documentation; (ii)
return to OAOHS all Software and Documentation delivered to Customer, (iii)
together with any and all copies of the Software and Documentation; (iv) delete
all copies of Software from all machine readable media in Customer's possession
