ATTACHMENT B – TERMS AND CONDITIONS

The parties agree to the following:

The agreement of the parties consists of the Service Order and all Attachments
(“Agreement”).

1. License. During the Term and subject to Publisher's compliance with this
Agreement, Overture grants to Publisher a limited, non-exclusive, non-assignable
(except as provided in Section 25), non-transferable, non-sublicensable (except
as explicitly provided for under this Agreement to Affiliates approved in
accordance with the Syndication Attachment), royalty-free worldwide right and
license to [*] the Links on and in the Publisher’s Offerings, send queries from
Publisher’s Offerings to Overture and to [*] the Results provided by Overture on
and through Publisher’s Offerings, solely for purposes contemplated in this
Agreement. The above license includes the limited right to use and reproduce the
software code and/or URLs that allow Publisher to create Links, send Queries
from Publisher’s Offerings to Overture and receive, transmit and display
Results.

2. Services. Overture will [*] respond to Queries by delivering Results or a
response that no Results are being delivered. [*] Publisher further acknowledges
and agrees that, except as provided in this Agreement, Publisher will not be
entitled to, nor seek, [*]. By way of example, and without limitation, under the
New Platform, Advertisers will have the ability to [*]. Overture reserves the
right (a) [*], (b) [*]. Overture shall not [*].

3. Publisher's Offerings. This Agreement applies to the Publisher’s Offerings as
defined in Section 31 below.

4. Future Offerings. Publisher will [*] notify Overture of any additional
websites or software applications owned by Publisher for use or distribution to
end-users that include (or that Publisher anticipates will include) search
functionality or paid listings. The parties may amend the SO to include such
additional offerings. [*]

5. Compensation.

(a)      [*]   (b)      [*]  

6. Payment. For each month during the Term, Overture or Overture Related Parties
will pay Publisher in accordance with the SO within [*] days after the end of
the calendar month in which the relevant Results appeared on Publisher's
Offerings (“Payment Period”). All payments (a) with respect to the U.S. and
Canada will be made in US dollars, (b) with respect to the United Kingdom will
be made in British pounds, and (c) with respect to all other countries in the
Territory will be made in Euros. If Overture or an Overture Related Party’s
Advertisers pay Overture or such Overture Related Party in any other currency,
Overture will calculate payment using the average exchange rate as published by
a nationally recognized source (e.g., Oanda). If the Territory includes
countries other than the United States, Publisher acknowledges that payment will
only be made after Publisher fulfills Overture’s invoicing requirements.
Overture may offset payments by any amounts Publisher owes to Overture,
including previous overpayments and any Multimedia Fees earned by Overture
during the Payment Period. In the event that Overture refunds amounts to
Advertisers in excess of its payment to Publisher and there are no future
payments to Publisher to offset against, Publisher will pay Overture for such
amounts within [*] days of Overture’s request. Overture may make payments only
when Publisher's balance exceeds US $250.00 (or until termination or expiration
of this Agreement). Except as specifically set forth in this Section, Overture
will retain all revenues derived from or in connection with its services.

7. Reports. Overture will provide Publisher with a monthly report describing in
reasonable detail how the payments provided for hereunder were determined and
will provide Publisher with access to preliminary daily online data on the
performance of the Results on Publisher's Offerings. Such online data will

provisions of this Agreement; provided further that notwithstanding anything
else contained herein, Overture may disclose such Confidential Information to
Overture Related Parties, subject to their obligation to keep such information
confidential.

8. Audits. [*] each year during the Term and for [*] after the Term, at the
expense of the auditing party, Publisher and Overture may review the other
party’s records to confirm compliance with the terms of this Agreement.
Notwithstanding the prior sentence, if the auditing party has a reasonable
belief that the other party is not complying with the terms of this Agreement,
then the auditing party shall be entitled to conduct a second audit during such
one-year period [*]. All audits under this section must be during normal
business hours, must not unduly interfere with the party being audited and must
be performed through a reputable, independent certified public accounting firm
reasonably acceptable to the other party (the “audited party”). Prior to an
audit, the party requesting the audit will require the auditor to sign a
confidentiality agreement reasonably similar to the form of the audited party’s
standard confidentiality agreement. All information received by either party in
connection with an audit under this section shall be subject to the
confidentiality obligations of this Agreement. Such audit shall occur during
business hours upon at least [*] notice and shall be conducted in accordance
with generally accepted auditing standards, if applicable, and the reviewer may
disclose only whether or not the audited party is in compliance, and the degree
and amount of any non-compliance, and may not disclose other information
(including to the auditing party) without written consent of the audited party.
[*]

9. Ownership. As between Overture and Publisher, all right, title and interest
in Links, Results, and the Yahoo! trademarks are exclusively owned by Overture,
its licensors and/or its Advertisers, and all right, title and interest in
Publisher's Offerings, the Publisher Content and the Publisher trademarks,
including

licensors.

10. No Implied Licenses. Each party reserves any rights not expressly granted
and disclaims all implied licenses, including implied licenses to trademarks and
patents.

serving and quality systems, Publisher will [*] provide such additional data,
provided the provision of such data to Overture does not [*]. Publisher will
provide this information along with the Internet Protocol address of its own or
the Affiliate’s server, as the case may be, at the time a Query is sent to
Overture. For clarity, Publisher will not share any [*] with Overture as part of
sending Queries to Overture hereunder (incidental transmission of [*] is
excluded). Additionally, Publisher will utilize the URLs and other source feed

event prior to disclosure of confidential Information) and shall reasonably
cooperate to seek confidential treatment, including the incorporation of
reasonably requested proposed redactions, and to obtain an appropriate
protective order to preserve the confidentiality of the Confidential
Information. All obligations under this Section survive until the latter of 3
years after termination of the Agreement or until such information is in the
public domain. The parties intend the foregoing to provide the maximum
protection for each party’s respective trade secrets. Overture acknowledges and
agrees that, subject to the exclusions set forth in the definition of
Confidential Information in Section 31 below, any information Publisher provides
to Overture hereunder for the purpose of obtaining or maintaining Overture’s

in the Agreement. In the event that Publisher fails to perform, keep, observe,
or fulfill any obligation in the manner provided in the Agreement (following any
applicable cure periods), Parent immediately shall cure or remedy each of such
obligations to be performed, kept, observed, or fulfilled.

Publisher consents and agrees that, without notice to or by Parent and without

proceeding.

Parent represents and warrants to Overture that Publisher has the requisite
authority to provide the representations and warranties as set forth in Section
