                               REGISTRY AGREEMENT

This REGISTRY AGREEMENT ("Agreement") is by and between the Internet
Corporation for Assigned Names and Numbers, a not-for-profit corporation, and
Network Solutions, Inc., a Delaware corporation.

DEFINITIONS

         For purposes of this Agreement, the following definitions shall apply:

         1. A "Consensus Policy" is one adopted by ICANN as follows:

         (a) "Consensus Policies" are those adopted based on a consensus among
         Internet stakeholders represented in the ICANN process, as
         demonstrated by (1) the adoption of the policy by the ICANN Board of
         Directors, (2) a recommendation that the policy should be adopted by
         at least a two-thirds vote of the council of the ICANN Supporting
         Organization to which the matter is delegated, and (3) a written
         report and supporting materials (which must include all substantive
         submissions to the Supporting Organization relating to the proposal)
         that (i) documents the extent of agreement and disagreement among
         impacted groups, (ii) documents the outreach process used to seek to
         achieve adequate representation of the views of groups that are likely
         to be impacted, and (iii) documents the nature and intensity of
         reasoned support and opposition to the proposed policy.

         (b) In the event that NSI disputes the presence of such a consensus,
         it shall seek review of that issue from an Independent Review Panel
         established under ICANN's bylaws. Such review must be sought within
         fifteen working days of the publication of the Board's action adopting
         the policy. The decision of the panel shall be based on the report and
         supporting materials required by subsection (a) above. In the event
         that NSI seeks review and the Panel sustains the Board's determination
         that the policy is based on a consensus among Internet stakeholders
         represented in the ICANN process, then NSI must implement such policy
         unless it promptly seeks and obtains injunctive relief under Section
         13 below.

         (c) If, following a decision by the Independent Review Panel convened
         under subsection (b) above, NSI still disputes the presence of such a
         consensus, it may seek further review of that issue within fifteen
         working days of publication of the decision in accordance with the
         dispute resolution procedures set forth in Section 13 below; provided,
         however, that NSI must continue to implement the policy unless it has
         obtained injunctive relief under Section 13 below or a final decision
         is rendered in accordance with the provisions of Section 13 that
         relieves NSI of such obligation. The decision in any such further
         review shall be based on the report and supporting materials required
         by subsection (a) above.

         (d) A policy adopted by the ICANN Board of Directors on a temporary
         basis, without a prior recommendation by the council of an ICANN
         Supporting Organization, shall also be considered to be a Consensus
         Policy if adopted by the ICANN Board of Directors by a vote of at
         least two-thirds of its members, and if immediate temporary adoption
         of a policy on the subject is necessary to maintain the stability of
         the Internet or the operation of the domain name system, and if the
         proposed policy is as narrowly tailored as feasible to achieve those
         objectives. In adopting any policy under this provision, the ICANN
         Board of Directors shall state the period of time for which the policy
         is temporarily adopted and shall immediately refer the matter to the
         appropriate Supporting Organization for its evaluation and review with
         a detailed explanation of its reasons for adopting the temporary
         policy and why the Board believes the policy should receive the
         consensus support of Internet stakeholders. If the period of time for
         which the policy is adopted exceeds 45 days, the Board shall reaffirm
         its temporary adoption every 45 days for a total period not to exceed
         180 days, in order to maintain such policy in effect until such time
         as it meets the standard set forth in subsection (a) above. If the
         standard set forth in subsection (a) above is not met within the
         temporary period set by the Board, or the council of the Supporting
         Organization to which it has been referred votes to reject the
         temporary policy, it will no longer be a "Consensus Policy."

         (e) For all purposes under this Agreement, the policies identified in
         Appendix A adopted by the ICANN Board of Directors before the
         effective date of this Agreement shall be treated in the same manner
         and have the same effect as "Consensus Policies."

         (f) In the event that, at the time the ICANN Board adopts a policy
         under subsection (a) above during the term of this Agreement, ICANN
         does not have in place an Independent Review Panel established under
         ICANN's bylaws, the fifteen working day period allowed under
         subsection (b) above to seek review shall be extended until fifteen
         working days after ICANN does have such an Independent Review Panel in
         place and NSI shall not be obligated to comply with the policy in the
         interim.

         2. The "Effective Date" is the date on which the Agreement is signed
by ICANN and NSI.

         3. The "Expiration Date" is the date specified in Section 23 below.

         4. "gTLDs" means the .com, .net, and .org TLDs, and any new gTLDs
established by ICANN.

         5. "ICANN" refers to the Internet Corporation for Assigned Names and
Numbers, a party to this Agreement.

AGREEMENTS

         NSI and ICANN agree as follows:

         1. Designation of Registry. ICANN acknowledges and agrees that NSI is
and will remain the registry for the Registry TLD(s) throughout the Term of
this Agreement.

         2. Recognition in Authoritative Root Server System. In the event and
to the extent that ICANN is authorized to set policy with regard to an
authoritative root server system, it will ensure that (A) the authoritative
root will point to the TLD zone servers designated by NSI for the Registry TLDs
throughout the Term of this Agreement and (B) any changes to TLD zone server
designation submitted to ICANN by NSI will be implemented by ICANN within five
business days of submission. In the event that this Agreement is

terminated (A) under Section 14 or 16(B) by NSI or (B) under Section 24 due to
the withdrawal of recognition of ICANN by the United States Department of
Commerce, ICANN's obligations concerning TLD zone server designations for the
 .com, .net, and .org TLDs in the authoritative root server system shall be as
stated in a separate agreement between ICANN and the Department of Commerce.

         3. General Obligations of NSI.

                  (A) During the Term of this Agreement:

                           (i) NSI agrees that it will operate the registry for
                  the Registry TLDs in accordance with this Agreement;

                           (ii) NSI shall comply, in its operation of the
                  registry, with all Consensus Policies insofar as they:

                                    (a) are adopted by ICANN in compliance with
                           Section 4 below,

                                    (b) relate to one or more of the following:
                           (1) issues for which uniform or coordinated
                           resolution is reasonably necessary to facilitate
                           interoperability, technical reliability and/or
                           stable operation of the Internet or domain-name
                           system, (2) registry policies reasonably necessary
                           to implement Consensus Policies relating to
                           registrars, or (3) resolution of disputes regarding
                           the registration of domain names (as opposed to the
                           use of such domain names), and

                                    (c) do not unreasonably restrain
                           competition.

                  (B) NSI acknowledges and agrees that upon the earlier of (i)
         the Expiration Date or (ii) termination of this Agreement by ICANN
         pursuant to Section 14, it will cease to be the registry for the
         Registry TLDs, unless prior to the end of the term of this Agreement
         NSI is chosen as the Successor Registry in accordance with the
         provisions of this Agreement.

                  (C) To the extent that Consensus Policies are adopted in
         conformance with Section 4 of this Agreement, the measures permissible
         under Section 3(A)(ii)(b) shall include, without limitation:

                           (i) principles for allocation of SLD names (e.g.,
                  first-come/first-served, timely renewal, holding period after
                  expiration);

                           (ii) prohibitions on warehousing of or speculation
                  in domain names

                  by registries or registrars;

                           (iii) reservation of SLD names that may not be
                  registered initially or that may not be renewed due to
                  reasons reasonably related to (a) avoidance of confusion
                  among or misleading of users, (b) intellectual property, or
                  (c) the technical management of the DNS or the Internet
                  (e.g., "example.com" and single-letter/digit names);

                           (iv) the allocation among continuing registrars of
                  the SLD names sponsored in the registry by a registrar losing
                  accreditation; and

                           (v) dispute resolution policies that take into
                  account the use of a domain name.

         Nothing in this Section 3 shall limit or otherwise affect NSI's
obligations as set forth elsewhere in this Agreement.

         4. General Obligations of ICANN. With respect to all matters that
impact the rights, obligations, or role of NSI, ICANN shall during the Term of
this Agreement:

                  (A)  exercise its responsibilities in an open and transparent
         manner;

                  (B) not unreasonably restrain competition and, to the extent
         feasible, promote and encourage robust competition;

                  (C) not apply standards, policies, procedures or practices
         arbitrarily, unjustifiably, or inequitably and not single out NSI for
         disparate treatment unless justified by substantial and reasonable
         cause; and

                  (D) ensure, through its reconsideration and independent
         review policies, adequate appeal procedures for NSI, to the extent it
         is adversely affected by ICANN standards, policies, procedures or
         practices.

         5. Protection from Burdens of Compliance With ICANN Policies. ICANN
hereby agrees to indemnify and hold harmless NSI, and its directors, officers,
employees and agents from and against any and all claims, damages or
liabilities arising solely from NSI's compliance as required by this Agreement
with an ICANN policy adopted after both parties have entered into this
Agreement, except that NSI shall not be indemnified or held harmless hereunder
to the extent that the claims, damages or liabilities arise from the particular
manner in which NSI has chosen to comply with the policy. In addition, NSI
shall be given a reasonable period after receiving notice of adoption of an
ICANN Consensus Policy in which to comply with that policy.

         6. NSI Registry-Level Financial Support of ICANN. NSI, in its role as
operator of the registry for the Registry TLDs, shall pay the gTLD
registry-level fees adopted by ICANN in conformance with Section 4 of this
Agreement, provided such fees are reasonably allocated among all gTLD
registries that contract with ICANN and provided further that, if NSI's share
of the total gTLD registry-level fees are or are budgeted to be in excess of
$250,000 in any given year, any such excess must be expressly approved by gTLD
registries accounting, in aggregate, for payment of two-thirds of all gTLD
registry-level fees. NSI shall pay such fees in a timely manner throughout the
Term of this Agreement, and notwithstanding the pendency of any dispute between
NSI and ICANN. NSI agrees to prepay $250,000 toward its share of gTLD
registry-level fees at the time of signing of this Agreement.

         7. Data Escrow. NSI shall deposit into escrow all Registry Data on a
schedule (not more frequently than weekly for a complete set of Registry Data,
and daily for incremental updates) and in an electronic format mutually
approved from time to time by NSI and ICANN, such approval not to be
unreasonably withheld by either party. The escrow shall be maintained, at NSI's
expense, by a reputable escrow agent mutually approved by NSI and ICANN, such
approval also not to be unreasonably withheld by either party. The escrow shall
be held under an agreement among ICANN, NSI, the United States Department of
Commerce, and the escrow agent providing that (A) the data shall be received
and held in escrow, with no use other than verification that the deposited data
is complete and in proper format, until released to ICANN or to the United
States Department of Commerce; (B) the data shall be released to ICANN upon
termination of this Agreement by ICANN under Section 14 or upon the Expiration
Date if (1) this Agreement has not sooner been terminated and (2) it has been
finally determined by the ICANN Board (and no injunction obtained pursuant to
Section 13 has been obtained) that NSI will not be designated as the successor
registry under Section 22 of this Agreement; and (C), in the alternative, the
data shall be released to the United States Department of Commerce according to
the terms of the cooperative agreement between NSI and the United States
Government.

         8. NSI Handling of Personal Data. NSI agrees to notify registrars
sponsoring registrations in the registry of the purposes for which Personal
Data submitted to the registry by registrars is collected, the recipients (or
categories of recipients) of such Personal Data, and the mechanism for access
to and correction of such Personal Data. NSI shall take reasonable steps to
protect Personal Data from loss, misuse, unauthorized disclosure, alteration or
destruction. NSI shall not use or authorize the use of Personal Data in a way
that is incompatible with the notice provided to registrars.

         9. Publication by NSI of Registry Data.

                  (A) NSI shall provide an interactive web page and a port 43
         Whois service providing free public query-based access to up-to-date
         (i.e. updated at least daily) registry database data which, in response
         to input of an SLD name, shall report at

                                      -20-

   7

         least the following data elements in response to queries: (a) the SLD
         name registered, (b) the TLD in which the SLD is registered; (c) the
         IP addresses and corresponding names of the primary nameserver and
         secondary nameserver(s) for such SLD, (d) the identity of the
         sponsoring Registrar, and (e) the date of the most recent modification
         to the domain name record in the registry database; provided, however,
         that if ICANN adopts a Consensus Policy that adds to or subtracts from
         these elements, NSI will implement that policy.

                  (B) To ensure operational stability of the registry, NSI may
         temporarily limit access under subsection (A), in which case NSI shall
         immediately notify ICANN of the nature of and reason for the
         limitation. NSI shall not continue the limitation longer than three
         business days if ICANN objects in writing, which objection shall not
         be unreasonably made. Such temporary limitations shall be applied in a
         nonarbitrary manner and shall apply fairly to any registrar similarly
         situated, including NSI.

                  (C) NSI as registry shall comply with Consensus Policies
         providing for development and operation of a capability that provides
         distributed free public query-based (web and command-line) access to
         current registration data implemented by registrars providing for
         capabilities comparable to WHOIS, including (if called for by the
         Consensus Policy) registry database lookup capabilities according to a
         specified format. If such a service implemented by registrars on a
         distributed basis does not within a reasonable time provide reasonably
         robust, reliable and convenient access to accurate and up-to-date
         registration data, NSI as registry shall cooperate and, if reasonably
         determined to be necessary by ICANN (considering such possibilities as
         remedial action by specific registrars), provide data from the
         registry database to facilitate the development of a centralized
         service providing equivalent functionality in a manner established by
         a Consensus Policy.

         10. Rights in Data. Except as permitted by the Registrar License and
Agreement, NSI shall not be entitled to claim any intellectual property rights
in data in the registry supplied by or through registrars other than NSI. In
the event that Registry Data is released from escrow under Section 7 or
transferred to a Successor Registry under Section 22(D), any rights held by NSI
as registry in the data shall automatically be licensed on a non-exclusive,
irrevocable, royalty-free, paid-up basis to the recipient of the data.

         11. Limitation of Liability. Neither party shall be liable to the
other under this Agreement for any special, indirect, incidental, punitive,
exemplary or consequential damages.

         12. Specific Performance. During the Term of this Agreement, either
party may seek specific performance of any provision of this Agreement as
provided by Section 13, provided the party seeking such performance is not in
material breach of its obligations.

         13. Resolution of Disputes Under This Agreement. Disputes arising
under or in connection with this Agreement, including requests for specific
performance, shall be resolved in a court of competent jurisdiction or, at the
election of both parties (except for any dispute over whether a policy adopted
by the Board is a Consensus Policy, in which case at the election of either
party), by an arbitration conducted as provided in this Section pursuant to the
International Arbitration Rules of the American Arbitration Association
("AAA"). The arbitration shall be conducted in English and shall occur in Los
Angeles County, California, USA. There shall be three arbitrators: each party
shall choose one arbitrator and, if the two arbitrators are not able to agree
on a third arbitrator, the third shall be chosen by the AAA. The parties shall
bear the costs of the arbitration in equal shares, subject to the right of the
arbitrators to reallocate the costs in their award as provided in the AAA
rules. The parties shall bear their own attorneys' fees in connection with the
arbitration, and the arbitrators may not reallocate the attorneys' fees in
conjunction with their award. The arbitrators shall render their decision
within ninety days of the initiation of arbitration. In all litigation
involving ICANN concerning this Agreement (whether in a case where arbitration
has not been elected or to enforce an arbitration award), jurisdiction and
exclusive venue for such litigation shall be in a court located in Los Angeles,
California, USA; however, the parties shall also have the right to enforce a
judgment of such a court in any court of competent jurisdiction. For the
purpose of aiding the arbitration and/or preserving the rights of the parties
during the pendency of an arbitration, the parties shall have the right to seek
temporary or preliminary injunctive relief from the arbitration panel or a
court located in Los Angeles, California, USA, which shall not be a waiver of
this arbitration agreement.

         14.  Termination.

                  (A) In the event an arbitration award or court judgment is
         rendered specifically enforcing any provision of this Agreement or
         declaring a party's rights or obligations under this Agreement, either
         party may, by giving written notice, demand that the other party
         comply with the award or judgment. In the event that the other party
         fails to comply with the order or judgment within ninety days after
         the giving of notice (unless relieved of the obligation to comply by a
         court or arbitration order before the end of that ninety-day period),
         the first party may terminate this Agreement immediately by giving the
         other party written notice of termination.

                  (B) In the event of termination by DOC of its Cooperative
         Agreement with NSI pursuant to Section I.B.8 of Amendment 19 to that
         Agreement, ICANN shall, after receiving express notification of that
         fact from DOC and a request from DOC to terminate NSI as the operator
         of the registry database for the Registry TLDs, terminate NSI's rights
         under this Agreement, and shall cooperate with DOC to facilitate the
         transfer of the operation of the registry database to a successor
         registry.

         15. Assignment. Neither party may assign this Agreement without the
prior written approval of the other party, such approval not to be unreasonably
withheld. Notwithstanding the foregoing sentence, a party may assign this
Agreement by giving written notice to the other party in the following
circumstances, provided the assignee agrees in writing with the other party to
assume the assigning party's obligations under this Agreement: (a) NSI may
assign this Agreement as part of the transfer of its registry business approved
under Section 25 and (b) ICANN may, in conjunction with a reorganization or
reincorporation of ICANN and with the written approval of the Department of
Commerce, assign this Agreement to another non-profit corporation organized for
the same or substantially the same purposes as ICANN.

         16. Relationship to Cooperative Agreement Between NSI and U.S.
Government.

                  (A) NSI's obligations under this Agreement are conditioned on
         the agreement by NSI and the Department of Commerce to Amendment 19 to
         the Cooperative Agreement in the form attached to this Agreement as
         Appendix C.

                  (B) If within a reasonable period of time ICANN has not made
         substantial progress towards having entered into agreements with
         competing registries and NSI is adversely affected from a competitive
         perspective, NSI may terminate this Agreement with the approval of the
         U.S. Department of Commerce. In such event, as provided in Section
         16(A) above, the Cooperative Agreement shall replace this Agreement.

                  (C) In the case of conflict while they are both in effect,
         and to the extent that they address the same subject in an
         inconsistent manner, the term(s) of the Cooperative Agreement shall
         take precedence over this Agreement.

         17. NSI Agreements with Registrars. NSI shall make access to the
Shared Registration System available to all ICANN-accredited registrars subject
to the terms of the NSI/Registrar License and Agreement (attached as Appendix
B). Such agreement may be revised by NSI, provided however, that any such
changes must be approved in advance by ICANN. Such agreement shall also be
revised to incorporate any Registry Service Level Agreement implemented under
Section 18.

         18. Performance and Functional Specifications for Registry Services.
Unless and until ICANN adopts different standards as a Consensus Policy
pursuant to Section 4, NSI shall provide registry services to ICANN-accredited
registrars meeting the performance and functional specifications set forth in
SRS specification version 1.0.6 dated September 10, 1999, as supplemented by
Appendix E and any Registry Service Level Agreement established according to
this Section 18. In the event ICANN adopts different performance and functional
standards for the registry as a Consensus Policy in compliance with Section 4,
NSI shall comply with those standards to the extent practicable, provided

Registry Agreement--

NSI/USG Cooperative Agreement
                                      -23-

   10

that compensation pursuant to the provisions of Section 20 has been resolved
prior to implementation and provided further that NSI is given a reasonable
time for implementation. In no event shall NSI be required to implement any
different functional standards before 3 years from the Effective Date of this
Agreement.

         Within 45 days after the Effective Date, (i) representatives
designated by ICANN of registrars accredited by ICANN for the Registry TLDs and
(ii) NSI will establish a Registry Service Level Agreement for the registry
system that shall include, at least:

                  (A) identified service level parameters and measurements
         regarding performance of the registry system, including, for example,
         system availability;

                  (B) responsibilities of registrars using the registry system
         and NSI (e.g., the obligation of the registrars to notify NSI of any
         experienced registry system outages and the obligation of NSI to
         respond in a timely manner to registry system outages);

                  (C) an appropriate service-level dispute-resolution process;
         and

                  (D) remedies for failure to comply with the Registry Service
         Level Agreement.

         Unless the Registry Service Level Agreement requires fundamental
architecture changes to the registry system or extraordinary increases in costs
to NSI beyond what is generally required to implement a service level agreement
(which is not the intent of the parties) the creation and implementation of the
Registry Service Level Agreement shall not result in a price increase under
Section 20.

         The 45-day drafting process for the Registry Service Level Agreement
shall be structured as follows: (E) the designated representatives and NSI (the
"SLA Working Group") shall promptly meet and shall within 20 days after the
Effective Date complete a draft of the Registry Service Level Agreement; (F)
all registrars accredited by ICANN for the Registry TLDs shall have 10 days
after distribution of that draft to submit comments to the SLA Working Group;
and (G) the SLA Working Group shall meet again to finalize the Registry Service
Level Agreement, taking into account the comments of the registrars. The 45-day
period shall be subject to extension by mutual agreement of the members of the
SLA Working Group. The SLA shall be implemented as soon as reasonably feasible
after its completion and approval by ICANN, including by implementation in
stages if appropriate.

         After it is approved by the SLA Working Group and ICANN, the Registry
Service Level Agreement shall be incorporated in the NSI/Registrar License and
Agreement referred to in Section 17.

         19. Bulk Access to Zone Files. NSI shall provide third parties bulk
access to the zone files for .com, .net, and .org TLDs on the terms set forth
in the zone file access agreement (attached as Appendix D). Such agreement may
be revised by NSI, provided however, that any such changes must be approved in
advance by ICANN.

         20. Price for Registry Services. The price(s) to accredited registrars
for entering initial and renewal SLD registrations into the registry database
and for transferring a SLD registration from one accredited registrar to
another will be as set forth in Section 5 of the Registrar License and
Agreement (attached as Appendix B). These prices shall be increased through an
amendment to this Agreement as approved by ICANN and NSI, such approval not to
be unreasonably withheld, to reflect demonstrated increases in the net costs of
operating the registry arising from (1) ICANN policies adopted after the date
of this Agreement, or (2) legislation specifically applicable to the provision
of Registry Services adopted after the date of this Agreement, to ensure that
NSI recovers such costs and a reasonable profit thereon; provided that such
increases exceed any reductions in costs arising from (1) or (2) above.

         21.  Additional NSI Obligations.

                  (A) NSI shall provide all licensed Accredited Registrars
         (including NSI acting as registrar) with equivalent access to the
         Shared Registration System. NSI further agrees that it will make a
         certification to ICANN every six months, using the objective criteria
         set forth in Appendix F that NSI is providing all licensed Accredited
         Registrars with equivalent access to its registry services.

                  (B) NSI will ensure, in a form and through ways described in
         Appendix F that the revenues and assets of the registry are not
         utilized to advantage NSI's registrar activities to the detriment of
         other registrars.

         22. Designation of Successor Registry.

                  (A) Not later than one year prior to the end of the term of
         this Agreement, ICANN shall, in accordance with Section 4, adopt an
         open, transparent procedure for designating a Successor Registry. The
         requirement that this procedure be opened one year prior to the end of
         the Agreement shall be waived in the event that the Agreement is
         terminated prior to its expiration.

                  (B) NSI or its assignee shall be eligible to serve as the
         Successor Registry and neither the procedure established in accordance
         with subsection (A) nor the fact that NSI is the incumbent shall
         disadvantage NSI in comparison to other entities seeking to serve as
         the Successor Registry.

                  (C) If NSI or its assignee is not designated as the Successor
         Registry, NSI or its assignee shall cooperate with ICANN and with the
         Successor Registry in

ICANN/Network Solutions, Inc.
Registry Agreement--

                                      -25-

   12


         order to facilitate the smooth transition of operation of the registry
         to Successor Registry. Such cooperation shall include the timely
         transfer to the Successor Registry of an electronic copy of the
         registry database and of a full specification of the format of the
         data.

                  (D) ICANN shall select as the Successor Registry the eligible
         party that it reasonably determines is best qualified to perform the
         registry function under terms and conditions developed as a Consensus
         Policy, taking into account all factors relevant to the stability of
         the Internet, promotion of competition, and maximization of consumer
         choice, including without limitation: functional capabilities and
         performance specifications proposed by the eligible party for its
         operation of the registry, the price at which registry services are
         proposed to be provided by the party, relevant experience of the
         party, and demonstrated ability of the party to handle operations at
         the required scale. ICANN shall not charge any additional fee to the
         Successor Registry.

                  (E) In the event that a party other than NSI or its assignee
         is designated as the Successor Registry, NSI shall have the right to
         challenge the reasonableness of ICANN's failure to designate NSI or
         its assignee as the Successor Registry under the provisions of Section
         13 of this Agreement.

         23. Expiration of this Agreement. The Expiration Date shall be four
years after the Effective Date, unless extended as provided below. In the event
that NSI completes the legal separation of ownership of its Registry Services
business from its registrar business by divesting all the assets and operations
of one of those businesses within 18 months after Effective Date to an
unaffiliated third party that enters an agreement enforceable by ICANN and the
Department of Commerce (i) not to be both a registry and a registrar in the
Registry TLDs, and (ii) not to control, own or have as an affiliate any
individual(s) or entity(ies) that, collectively, act as both a registry and a
registrar in the Registry TLDs, the Expiration Date shall be extended for an
additional four years, resulting in a total term of eight years. For the
purposes of this Section, "unaffiliated third party" means any entity in which
NSI (including its successors and assigns, subsidiaries and divisions, and
their respective directors, officers, employees, agents and representatives)
does not have majority equity ownership or the ability to exercise managerial
or operational control, either directly or indirectly through one or more
intermediaries. "Control," as used in this Section 23, means any of the
following: (1) ownership, directly or indirectly, or other interest entitling
NSI to exercise in the aggregate 25% or more of the voting power of an entity;
(2) the power, directly or indirectly, to elect 25% or more of the board of
directors (or equivalent governing body) of an entity; or (3) the ability,
directly or indirectly, to direct or cause the direction of the management,
operations, or policies of an entity.

         24. Withdrawal of Recognition of ICANN by the Department of Commerce.
In the event that, prior to the expiration or termination of this Agreement
under Section 14 or 16(B), the United States Department of Commerce withdraws
its recognition of ICANN as NewCo under the Statement of Policy pursuant to the
procedures set forth in Section 5 of Amendment 1 (dated November 10, 1999) to
the Memorandum of Understanding between ICANN and the Department of Commerce,
this Agreement shall terminate.

         25. Assignment of Registry Assets. NSI may assign and transfer its
registry assets in connection with the sale of its registry business only with
the approval of the Department of Commerce.

         26. Option to Substitute Generic Agreement. At NSI's option, it may
substitute any generic ICANN/Registry agreement that may be adopted by ICANN
for this Agreement; provided, however, that Sections 16, 19, 20, 21, 23, 24,
and 25 of this Agreement will remain in effect following any such election by
NSI.

         27. Notices, Designations, and Specifications. All notices to be given
under this Agreement shall be given in writing at the address of the
appropriate party as set forth below, unless that party has given a notice of
change of address in writing. Any notice required by this Agreement shall be
deemed to have been properly given when delivered in person, when sent by
electronic facsimile, or when scheduled for delivery by internationally
recognized courier service. Designations and specifications by ICANN under this
Agreement shall be effective when written notice of them is deemed given to
Registry.
