automatically vest in Licensor, when and as, on an on-going basis, such
acquisition of goodwill or reputation occurs, as well as at the expiration or
termination of this Agreement, without any separate payment or other
consideration of any kind to Licensee, and Licensee agrees to take all such

the Term (as defined below), Inktomi shall pay N2H2 a minimum annual Information
Services Fee of * ("Minimum ISF") in accordance with the payment schedule set
forth below; provided, that, if the parties fail to: (i) agree on an Engineering

The fee statement shall be based upon the calculations set forth above during
the month and/or calendar quarter then ended, and shall contain information
reasonably sufficient to discern how the fees, if any, were computed. All
statements and all other accounts rendered by Inktomi to N2H2 shall be binding
upon N2H2 and not subject to any objections by N2H2 for any reason unless
specific objection in writing, stating the basis thereof, is received by Inktomi
within one (1) year from the date rendered.

        8.8. Records. Inktomi agrees to keep all proper records and books of
account and all proper entries therein relating to the fee calculations made
under Section 8.2. Such records and books of account shall be maintained for a

books of account from time to time but not more than once every year to verify
statements rendered under Section 8.2. Such examination shall be conducted at
reasonable times during Inktomi's normal business hours and upon at least ten
(10) business days' advance notice and in a manner so as not to interfere
unreasonably with the conduct of Inktomi's business. If any such examination
indicates that the audited party has underpaid or

                                        6
<PAGE>   7

overpaid N2H2 for any particular period, then N2H2 or Inktomi, as the case may
be, shall promptly remit the difference to the other party.

9. Confidentiality.

        9.1. Definition of Confidential Information. All information and
documents disclosed or produced by either party in the course of this Agreement
which are disclosed in written form and identified by a marking thereon as
proprietary, or oral information which is defined at the time of disclosure and
confirmed in writing within ten (10) business days of its disclosure, shall be
deemed the "Confidential Information" of the disclosing party. "Confidential
Information" includes without limitation the Inktomi Proxy, Inktomi Data
Protocol, the Inktomi Proxy Protocol and the Engineering Plan.

        9.2. Treatment of Confidential Information. Each party agrees to protect
the other party's Confidential Information in the same manner as such party
protects its own Confidential Information of substantially similar proprietary
value, but in no case less than reasonable care. Each party agrees that it will
use the Confidential Information of the other party only for the purposes of
this Agreement and that it will not divulge, transfer, sell, license, lease, or
otherwise disclose or release any such information or documents to third
parties, with the exception of: (i) its employees or subcontractors who require
access to such for purposes of carrying out such party's obligation hereunder;
and (ii) persons who are employed as auditors by a public accounting firm or by
a federal or state agency. Each party will use reasonable efforts to advise any
person obtaining Confidential Information that such information is proprietary
and to obtain a written agreement obligating such person to maintain the
confidentiality of any Confidential Information belonging to the party or it
suppliers.

        9.3. No Other Confidential Information. Neither party shall have any
obligation under this Article 9 for information of the other party which the
receiving party can substantiate with documentary evidence that has been or is:
(i) developed by the receiving party independently and without the benefit of
information disclosed hereunder by the disclosing party; (ii) lawfully obtained
by the receiving party from a third party without restriction and without breach
of this Agreement; (iii) publicly available without breach of this Agreement;
(iv) disclosed without restriction by the disclosing party to a third party; or
(v) known to the receiving party prior to its receipt from the disclosing party.

        9.4. Independent Development. Each party, as a discloser of Confidential
Information, understands that the other party, as recipient, may currently or in
the future be developing information internally, or receiving information from
other parties that may be similar to the disclosing party's information.
Accordingly, nothing in this Agreement will be construed as a representation or
inference that a party as a receiving party will not develop products or
services, or have products or services developed or provided for it that,
without violation of this Agreement, compete with the products or services
contemplated by a disclosing party's Confidential Information.

the right to employ separate counsel and participate in the defense of any claim
or action. The indemnifying party shall reimburse the indemnified party upon
demand for any payments made or loss suffered by it at any time after the date
hereof, based upon the judgment of any court of competent jurisdiction or

in respect to any damages related to any claim or action under this Article 11.

        11.4. Settlement. The indemnifying party may not settle any claim or
action under this Article 11 without first obtaining the indemnified party's
written permission, which permission will not be unreasonably withheld. In the

        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.
