        or any other costs or expenses) arising out of a material breach of this
        Agreement by N2H2 that does not also fall under clause (b) or (c),
        above.

15.     LICENSEE'S INDEMNIFICATION OF N2H2. Licensee will indemnify and defend
        N2H2 and its directors, officers, employees and agents, at Licensee's
        expense, against any and all claims, demands, losses, liabilities,

        under clause (b), above.

        shall have the right to allow its Authorized Users to use the Software
        as part of the BESS System as contemplated by this Agreement. Licensee's
        attempt to reverse engineer, decompose, disassemble or make any attempt
        to discover the Proprietary Content, Software or source code to the
        Software and/or the details of the Proprietary Content shall result in
        the immediate termination of this Agreement.

17.     ASSIGNMENT. The rights in this Agreement are personal to each party and
        will not be transferred or assigned by operation of law or otherwise
        except to a successor organization resulting from an acquisition, merger

        without the prior written consent of the other party. Any transfer or
        assignment in violation of this paragraph shall be void and will have no
        force or effect.

18.     FORCE MAJEURE. The Parties will not be in default and liable for breach

        labor disturbances, lockout, riot, fire, flood, outside electrical
        failure, outside telecommunications facilities failure, computer virus,
        act of God, or the public enemy, or any other cause, whether like or
        unlike the foregoing, if beyond the reasonable efforts of them to
        control and which may prevent or delay them from performing their
        obligations herein. All performance of both parties shall be excused
        during the continuance of such circumstances if the circumstances
        materially impair the value of this Agreement to the non-affected party.
        If the circumstances persist for more than thirty (30) days, the
        non-affected party shall have the night to immediately terminate this
        Agreement by sending notice of termination to the affected party.

        Licensee may attach to or modify N2H2 marketing materials to the extent
        necessary to provide contact information about Licensee, but may not

Licensee's breach, Licensee agrees to not develop any competing Internet content
filtering system for its own use, or a third party's use, without N2H2's written
approval.

21. REMEDIES. Licensee acknowledges and agrees that the use or release of
Proprietary Content in violation of this Agreement will cause irreparable harm
for which N2H2 may not be fully or adequately compensated by recovery of
monetary damages. Accordingly, in the event of any such violation or threatened
violation, N2H2 will be entitled to injunctive relief from a court of competent
jurisdiction in addition to monetary damages and any other remedy available at
law or in equity. If any action at law or in equity is brought to enforce or

disbursements in addition to any other relief that may be granted. Except as
provided in Paragraph 14, Licensee's exclusive remedy against N2H2 will be a
return of fees paid for the BESS System for the months in which a breach by N2H2
occurs. An action for any breach of this Agreement must be commenced within two
(2) years from the date when a party had knowledge of the alleged breach.

22. TERMINATION. Except as set forth in paragraph 15, in the event that any
breach or default of this Agreement by either party remains uncured for more
than ten (10) days after written notice from the other party, the non-breaching
party may terminate this Agreement and all rights hereunder by giving the
breaching party written notice of termination. Upon termination by either party,
N2H2 will have the right immediately to disconnect Licensee from the BESS System
and Licensee will promptly return the BESS System to N2H2 in good working
condition. N2H2 shall pay for all shipping and handling charges associated with

23. NOTICES. Any notice required by this Agreement or given in connection with
it, will be in writing and will be given to the appropriate party by personal
delivery or by certified mail, or recognized overnight delivery services.
Facsimile notice or email may be used only if a means of obtaining an immediate
written confirmation of receipt is available and such proof is presented in the
event of a dispute.

24. MISCELLANEOUS. The terms of this Agreement are binding on the Parties, their
subsidiaries, affiliates and any party controlling, controlled by or under
common control with the Parties, and their successors, licensees, agents and
employees. The invalidity or unenforceability of any provision hereof will in no
way affect the validity or enforceability of any other provision. The Parties
agree that this Agreement will be governed by the internal laws of the State of
Washington, without regard to Washington conflict of law' principles. Suits
relating to this Agreement must be brought in the appropriate state or federal
court in the state of Washington and the Parties submit to the jurisdiction of
such Washington courts.

25. CONFIDENTIALITY. The Parties agree to maintain the confidential nature of
all proprietary information disclosed or received during this relationship.
Proprietary information shall include lists of customers and prospects, product
or service development plans, all technical system information not on published
marketing materials, financial information, customer usage and billing reports,
software, and any other information identified as confidential or proprietary.
This responsibility will continue for five (5) years after termination of this
Agreement as long as the disclosing Party does not make such proprietary
information public.

26. ENTIRETY. This Agreement constitutes the complete agreement between N2H2 and
Licensee, and may not be modified except by written agreement of both Parties.

27. ADDITIONAL FEES. Payments to N2H2, as set forth in Schedule A, are exclusive

license, transfer or use of the BESS System. In the event N2H2 is charged such
taxes on the services provided in this Agreement, N2H2 may add an equal amount
to the total fees owed by Licensee hereunder. Any other services purchased by
Licensee from N2H2 will be payable through a separate invoice of N2H2.
