ARTICLE VII.  Indemnity, Insurance, Disclaimers

    Section 7.01   Indemnity.  Company shall defend and indemnify and hold

harmless from any judgements and other liabilities based upon claims or causes
of action against Dartmouth or its employees which arise out of alleged
negligence in the development, manufacture or sale of Licensed Products by
Company, its Subsidiaries, and sublicensees, or from the use by the end users of
Licensed Products, except to the extent that such judgements or liabilities
arise in whole or in part from the gross negligence or willful misconduct of
Dartmouth or its employees, provided that Dartmouth promptly notifies Company of
any such claim coming to its attention and that it cooperates with Company in
the defense of such claim.  If any such claims or causes of action are made,
Dartmouth shall be defended by counsel to Company, subject to Dartmouth's
approval, which shall not be unreasonably withheld.  Dartmouth reserves the
right to be represented by its own counsel at its own expense.

    Section 7.02  Insurance.  At such time as any product, process, service
relating to, or developed pursuant to, this Agreement is being commercially
distributed or sold (other than for the purpose of obtaining regulatory
approvals) by Company or by a sublicensee, Subsidiary or agent of Company,
Company shall at its sole cost and expense, procure and maintain comprehensive
general liability insurance in amounts not less than $[*] per incident  and
naming the Indemnitees as additional insureds.  Such comprehensive general
liability insurance shall provide (i) product liability coverage and (ii) broad
form contractual liability coverage for Company's indemnification under this
Agreement.  If Company elects to self-insure all or part of the limits described
above (including deductibles or retentions which are in excess of $[*] annual
aggregate) such self-insurance program must be acceptable to Dartmouth and
Dartmouth Risk Manager. Such insurance will be considered primary as to any
other valid and collectible insurance, but only as to acts of the named insured.
The minimum amounts of insurance coverage required shall not be construed to
create a limit of Company's liability with respect to its indemnification under
this Agreement.

    Company shall provide Dartmouth with written evidence of such insurance upon
request of Dartmouth.  Company shall provide Dartmouth with written notice at
least [*] days prior to the cancellation, non-renewal or material change in such
insurance; if Company does not obtain replacement insurance providing comparable
coverage within such [*] day period, Dartmouth shall have the right to terminate
this Agreement effective at the end of such [*] day period without notice or any
additional waiting periods.

    Company shall maintain such comprehensive general liability insurance beyond
the expiration or termination of this Agreement during (i) the period that any
product, process, or service, relating to, or developed pursuant to, this
Agreement is being commercially distributed or sold by Company or by a
sublicensee, Subsidiary or agent of Company and (ii) a reasonable period after
the period referred to in (i) above which in no event shall be less than fifteen
(15) years.

    Section 7.03  Disclaimer.  Nothing contained in this Agreement shall be
construed as:

    (a) a warranty or representation by Dartmouth as to the validity or scope of
any Patent Rights;
    (b) a warranty or representation that any Licensed Products manufac­tured,
used or sold will be free from infringement of patents, copyrights, or rights of
third parties, except that Dartmouth represents that it has no knowledge of any
existing issued patents or copyrights which might be infringed;
    (c) except as provided in Section 7.01, an agreement to defend against
actions or suits of any nature brought by any third parties.

DARTMOUTH MAKES NO WARRANTIES, EXPRESS OR IMPLIED, AS TO THE MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE OF LICENSED PRODUCTS

prompt notice of any incident of infringement of Dartmouth Patent Rights coming
to its attention.  The parties shall thereupon confer together as to what steps
are to be taken to stop or prevent such infringement.  Company shall be entitled
to commence proceedings in its own name against the infringer, in which event
Company shall be responsible for all legal costs incurred, without recourse to
Dartmouth, however Dartmouth agrees to appear as a party in any such proceedings
if requested by COMPANY and such request is not unreasonably burdensome on
Dartmouth. Company also agrees to reimburse Dartmouth for out of pocket costs
spent in connection with said request. Financial recoveries from any such
litigation will first be applied to reimburse Company for its litigation
expenditures and [*]% of additional recoveries will be paid to Dartmouth. If
Company chooses not to commence litigation within [*] days from the date the
parties confer regarding the infringement, Dartmouth may  commence proceedings
against the infringer, in which case Dartmouth shall be responsible for any
legal costs incurred  and will be entitled to retain any damages recovered.   In
any action to enforce Dartmouth Patent Rights, either party, at the request and
expense of the other party shall cooperate to the fullest extent reasonably
possible.  Company may not settle any infringement action in any way detrimental
to Dartmouth Patent Rights without the expressed written consent of Dartmouth.

within [*] days after said notice shall have been given, this Agreement shall
continue in full force and effect.  The failure on the part of either of the

exercise or enforcement thereof at any time or times thereafter.

this Agreement by giving three (3) months advance written notice to Dartmouth to
that effect and paying a termination fee of $[*]. Upon termination, a final
