shall defend or at its option settle, any claim brought against ALTAVISTA on
the issue of infringement of any copyright, United States patent, trade
secret or trademark of any third party to the extent attributable to the
RealNames Service, provided that ALTAVISTA provides Centraal with: (i) prompt
written notice of such claim, (ii) control over the defense and settlement of
such claim, and (iii) proper and full information and assistance to settle or
defend any such claim. If Centraal believes, in its sole discretion, that it
is likely that ALTAVISTA will be prohibited from exercising its right to use
the RealNames Service as provided under this Agreement, then Centraal may, at
its sole option and expense: (i) procure the right to use the RealNames
Service as provided herein, (ii) replace the RealNames Service with other
non-infringing services with equivalent functionality, (iii) suitably modify
the RealNames Service so that they do not infringe, or (iv)terminate this
Agreement. Notwithstanding the above, Centraal assumes no liability for
infringement claims arising from combination of the RealNames Service with
products or services not provided by Centraal, but not arising from the
RealNames Service standing alone. THE FOREGOING PROVISIONS OF THIS SECTION
9.1 STATE THE ENTIRE LIABILITY AND OBLIGATIONS OF CENTRAAL, AND THE EXCLUSIVE
REMEDY OF ALTAVISTA, WITH RESPECT TO ANY ACTUAL OR ALLEGED INFRINGEMENT OF

secret or trademark of any third-party by the Integrated Product (except to

ALTAVISTA with: (i) prompt written notice of such claim, (ii) control over
the defense and settlement of such claim, and (iii) proper and full
information and assistance to settle or defend any such claim. THE FOREGOING
PROVISIONS OF THIS SECTION 9.2 STATE THE ENTIRE LIABILITY AND OBLIGATIONS OF
ALTAVISTA, AND THE EXCLUSIVE REMEDY OF CENTRAAL, WITH RESPECT TO ANY ACTUAL
OR ALLEGED INFRINGEMENT OF ANY INTELLECTUAL PROPERTY RIGHT UNDER THIS
AGREEMENT.

       12.    CONFIDENTIALITY.

              12.1   CONFIDENTIAL INFORMATION. The term "Confidential
Information" means any information disclosed by one party to the other
pursuant to this, Agreement that is in written, graphic, machine readable or
other tangible form and is designated "Confidential", "Proprietary" or in
some other manner to indicate its confidential nature. Confidential
Information may also include oral information disclosed by one party to the
other pursuant to this Agreement, provided that such information is
designated as confidential at the time of disclosure and is reduced to
writing by the disclosing party within a reasonable time (not to exceed
thirty (30) days) after its oral disclosure, and such writing is marked in a
manner to indicate its confidential nature and delivered to the receiving
party. Confidential Information shall include (without limitation) any source

              12.2   CONFIDENTIALITY. Each party shall treat as confidential
all Confidential Information of the other party, shall not use such
Confidential Information except to exercise its rights and perform its
obligations under this Agreement herein, and shall not disclose such

party. Each party shall promptly notify the other party of any actual or
suspected misuse or unauthorized disclosure of the other party's Confidential
Information.

              12.3   EXCEPTIONS. Confidential Information excludes
information that: (i) was in the public domain at the time it was disclosed
or has become in the public domain through no fault of the receiving party;
(ii) was known to the receiving party, without restriction, at the time of
disclosure, as demonstrated by files in existence at the time of disclosure;
(iii) is disclosed with the prior written approval of the disclosing party;
(iv) was independently developed by the receiving party without any use of
the Confidential Information; (v) becomes known to the receiving party,
without restriction, from a source other than the disclosing party, without
breach of this Agreement, by the receiving party; or (vi) is disclosed
generally to third parties by the disclosing party without restrictions
similar to those contained in this Agreement. The receiving party may
disclose the other party's Confidential Information to the extent such
disclosure is required by order or requirement of a court, administrative
agency, or other governmental body, but only if the receiving party provides
prompt notice thereof to the disclosing party to enable the disclosing party
to seek a protective order or otherwise prevent or restrict such disclosure.

              12.4   CONFIDENTIALITY OF AGREEMENT. Each party may disclose
the existence of this Agreement, but agrees that the terms and conditions of

however, that each party may disclose the terms and conditions of this
Agreement: (i) as required by any court or other governmental body; (ii) as
otherwise required by law; (iii) to legal counsel of the parties; (iv) in
confidence, to accountants, banks, and financing sources and their advisors;
(v) in connection with the enforcement of this Agreement or rights under this
Agreement; or (vi) in confidence, in connection with an actual or proposed
merger, acquisition, or similar transaction. After the Effective Date of this
Agreement, Centraal shall issue a press release announcing this Agreement and
the inclusion of RealNames Service in the ALTAVISTA Product; provided
however, that prior to such press release, Centraal shall submit the press
release to ALTAVISTA for its approval, which shall not be unreasonably
withheld or delayed.

              12.5   SOURCE CODE SECURITY. In the event that Centraal
provides source code to ALTAVISTA, ALTAVISTA shall use the source code for
the Software only under carefully controlled conditions at Centraal's
facilities or ALTAVISTA's facilities for the purposes set forth in this
Agreement, and shall inform all employees who are given access to the
Software by ALTAVISTA that the source code of the Software is a confidential
trade secret of Centraal. ALTAVISTA shall restrict access to the Software to
those employees of ALTAVISTA who have agreed to be bound by a confidentiality
obligation substantially in the form of this Section 12, and who have a need
to access the source code to carry out the purposes of this Agreement. Upon
request by Centraal, ALTAVISTA shall provide Centraal with the names of all
individuals who have accessed such materials, and shall take all actions
reasonably required to recover any such materials in the event of loss or
misappropriation, or to otherwise prevent their unauthorized disclosure or
use. ALTAVISTA shall indemnify and hold harmless Centraal for any breach of
such confidentiality obligation or of this Agreement by any of ALTAVISTA's
employees, agents and representatives. Upon conclusion of the Localization in

   13.    GENERAL.

              13.1   INDEMNIFICATION OF CENTRAAL. In addition to the
intellectual property infringement claims provided for under Section 9,
ALTAVISTA shall indemnify and hold Centraal harmless against any liability,
or any litigation cost or expense (including attorneys' fees), arising out of
third party claims against Centraal as a result of ALTAVISTA's use or
distribution of the RealNames Service and Centraal Materials.

              13.2   PARTIAL INVALIDITY. If any provision in this Agreement
is found invalid or unenforceable, then the meaning of such provision will be
construed, to the extent feasible, so as to render the provision enforceable,
and if no feasible interpretation would save such provision, it will be
severed from the remainder of this Agreement, which will remain in full force
and effect, and the parties shall negotiate, in good faith, a substitute,
valid and enforceable provision that most nearly effects the parties' intent
in entering into this Agreement.

              13.3   INDEPENDENT CONTRACTORS. The parties hereto are
independent contractors. Nothing contained herein will constitute either
party the agent of the other party, or constitute the parties as partners or
joint venturers. ALTAVISTA shall make no representations or warranties on
behalf of Centraal with respect to the Software.

              13.4   MODIFICATION. No alteration, amendment, waiver,
cancellation or any other change in any term or condition of this Agreement
will be valid or binding on either party unless the same is mutually agreed
to in writing by both parties.

              13.5   WAIVER. The failure of either party to enforce at any
time any of the provisions of this Agreement, or the failure to require at
any time performance by the other party of any of the provisions of this
Agreement, will not be construed to be a waiver of such provisions, or in any
way affect the right of either party to enforce such provision thereafter.
The express waiver by either party of any provision of this Agreement will
not constitute a waiver of any future obligation to comply with such
provision.

              13.6   ASSIGNMENT. This Agreement will be binding upon and
inure to the benefit of the parties hereto and their respective successors
and assigns; provided, however, that neither party shall assign any of its
rights, obligations, or privileges (by operation of law or otherwise)
hereunder without the prior written consent of the other party.
Notwithstanding the foregoing, either party may assign this Agreement to a
successor in interest (or its equivalent) of all or substantially all of its
relevant assets, whether by sale, merger, or otherwise. In the event that the
ALTAVISTA Product is spun-off as part of a newly formed separate legal
entity, this Agreement shall be promptly and fully assigned to such entity.
Any attempted assignment in violation of this section shall be void.

              13.7   NOTICES. Any notice required or permitted to be given by
either party under this Agreement will be in writing and personally delivered
or sent by commercial courier service (e.g., DHL), or by first class airmail
(certified or registered if available), to the other party at its address
below, or such new address as may from time to time be supplied hereunder by
the parties hereto. If mailed, notices will be deemed effective five (5)
working days after deposit, postage prepaid, in the mail:

              13.9   PAYMENT. Payment must be in U.S. Dollars. All references

              13.10  FORCE MAJEURE. Notwithstanding anything else in this
Agreement, no default, delay or failure to perform on the part of either
party will be considered a breach of this Agreement if such default, delay or
failure to perform is shown to be due to causes beyond reasonable control of
the party charged with a default, including, but not limited to, causes such
as strikes, lockouts or other labor disputes, riots, civil disturbances,
actions or inactions of governmental authorities or suppliers, epidemics,
war, embargoes, severe weather, fire, earthquakes, acts of God or the public

by the Parties.

                                       Fees

A.            COMPENSATION FOR SUBSCRIPTIONS.

       ALTAVISTA's sole compensation under the terms of this Agreement for
solicitation of RealNames Subscribers shall be in accordance with this
Section A. During the term of this Agreement, ALTAVISTA shall receive a
commission which equals [*] of the initial Annual Net Subscription Fees [*]
actually received by Centraal for each paid subscription for a RealNames
Address generated through the co-branded registration pages on the Integrated
Product as provided for under the Agreement("ALTAVISTA Subscription
Commission").

       By way of example, Customer X pays a $100 subscription fee, which
there is a tax owing of $10 which has not been paid by Customer X, and which
Centraal must pay a third party provider of RealNames support services [*]
for Customer X. The payment owing to ALTAVISTA for ALTAVISTA Subscription
Commission of Customer X would be [*] of [*] ($100 less $10 (tax) and less
([*] third party payment)), or [*].

       The ALTAVISTA Subscription Commission on a given order will be due and
payable once per quarter. Centraal shall submit to ALTAVISTA at
[email protected] quarterly statements of the commission or annuities
due and payable to ALTAVISTA under the terms of this Section A of EXHIBIT B
within 30 days of the end of each such quarter, and such report shall be
accompanied with payment for such amounts owing in U.S. Dollars.

B.     COMPENSATION FOR REALNAMES RESOLUTION.

       During the term of this Agreement, ALTAVISTA's sole compensation for
the provision of RealNames Resolution services shall be in accordance with
this Section B. During the term of this Agreement, ALTAVISTA shall receive a
commission which equals [*] of Net RealNames Resolution Fees generated
through an Integrated Product ("ALTAVISTA Resolution Commission). ALTAVISTA
acknowledges and accepts that as of the Effective Date of this Agreement only
a limited number of RealNames Subscribers have agreed to compensate Centraal
on a RealNames Resolution basis.

       By way of example, assume that Customer Y pays on a per RealNames
Resolution basis and generates $1000 dollars worth of Real Names Resolutions
during the relevant quarter. Assume also, that 50% of such RealNames
Resolutions took place on an Integrated Product. Further assume that there is
a tax of $100 owing, and Centraal must pay a third party provider of
RealNames support services [*] for Customer Y. The payment owing to ALTAVISTA
for ALTAVISTA Resolution Commission of Customer Y would be [*] of [*] ($500
(50% of the $1000 resolution income) less $100 (tax) and less [*] (third
party payment)), or [*].

       The ALTAVISTA Resolution Commission on a given order will be due and
payable once per quarter. Centraal shall submit to ALTAVISTA at
[email protected] quarterly statements of the commission or annuities
due and payable to ALTAVISTA under the terms of

                                SUBSCRIBER AGREEMENT

               CENTRAAL CORPORATION REALNAMES SUBSCRIPTION AGREEMENT

A. INTRODUCTION.

This RealNames Subscription Agreement ("Agreement") is submitted to CENTRAAL
CORPORATION ("CENTRAAL") for the purpose of subscribing to CENTRAAL's
RealNames Service (SM) on the Internet through CENTRAAL's subscription system
also known as the RealNames System (SM). If this Agreement is accepted by
CENTRAAL, and a RealNames (SM) address is allocated in CENTRAAL's Web address
system to the Subscriber ("Subscriber"), Subscriber agrees to be bound by the
terms of this Agreement.

B. FEES AND PAYMENTS.

Subscriber agrees to pay a NON-REFUNDABLE fee of ____________(US$_____) per
year in consideration of each subscribed RealNames address. The payment may
be made payable either directly to "CENTRAAL Corporation," or indirectly to
CENTRAAL through a certified reseller.

This NON-REFUNDABLE fee covers a period of one (1) year for each new
subscription or reservation of a RealNames address. This NON-REFUNDABLE fee
includes any permitted modification(s) to the RealNames address record during
the subscription or reservation. It also covers up to ten thousand (10,000)
uses of the RealNames address per calendar month; CENTRAAL reserves the right
to stop processing uses of the RealNames address after ten thousand (10,000)
uses in a calendar month. Subscribers will be notified by CENTRAAL when a
RealNames address usage exceeds ten thousand (10,000) uses per calendar
month. Subscribers of a RealNames address which usage exceeds ten thousand
(10,000) uses per calendar month will be subject to additional usage fees, at
a rate to be agreed upon by CENTRAAL and Subscriber in advance of such
charges. In the event that CENTRAAL and Subscriber cannot agree on such fees,
Subscriber understands and agrees that CENTRAAL may terminate this Agreement
without liability, including Subscriber's use of any RealNames address.

All payments will be due within thirty (30) days from the date of invoice.
Subscriber understands and agrees that CENTRAAL may cancel Subscriber's
subscription or reservation in the event that any payment is not made when
due.

On the date of expiration, RealNames address subscriptions will be
automatically renewed for the period of one year, unless the Subscriber
notifies CENTRAAL in writing of its intention not to renew the RealNames
subscription. Notification to cancel automatic renewals must be communicated
to CENTRAAL by fax (1-650-858-0454) or email ([email protected]) at least
ten days prior to the RealNames subscription expiration date. Automatic
renewals will be billed at CENTRAAL's then-current annual subscription price.

C. ALLOCATION OF REALNAMES ADDRESSES BY CENTRAAL.

Subscriber agrees that allocation of RealNames addresses by CENTRAAL is
subject to CENTRAAL's discretion. CENTRAAL may at any time, with notice to
Subscriber that is reasonable in the circumstances (including immediate
notice when that is appropriate) reallocate a RealNames address previously or
currently used by Subscriber. Any notice provided to Subscriber will be at
the last address furnished by Subscriber to CENTRAAL. Subscriber understands
that all systems of address with respect to the Internet are subject to
varied and occasionally inconsistent principles, jurisdictions, and claims of
right. Subscriber understands and agrees that CENTRAAL requires absolute
discretion over, the allocation of RealNames addresses in light of the
uncertain and often conflicting principles that are at work in the current
state of the Internet. Subscriber understands and agrees that, because of
CENTRAAL's discretion, CENTRAAL has the absolute right to allocate RealNames
addresses, withdraw them, and reallocate them according to its own judgment
as to what constitutes an optimal service and system. Subscriber further
recognizes that CENTRAAL, with a view to optimizing its RealNames Service and
RealNames Services, may apply standards of decision regarding allocation,
reallocation, or withdrawal of RealNames addresses that evolve or change over
time. If CENTRAAL does

business, or competition rights upon Subscriber.

D. DISPUTES.

RealNames address, reservation or any other aspect of the RealNames Services

invoices for services and are due when the invoices are due.
