THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS NEUSTAR
EPP XRI MAPPING TOOLKIT PUBLIC LICENSE ("AGREEMENT"). ANY USE, 
REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES RECIPIENT'S 
ACCEPTANCE OF THIS AGREEMENT. 

1. DEFINITIONS 

1.1 "Contribution" means: 

    a.  in the case of NeuStar, Inc.  ("NeuStar"), the Original Program, and 
    b.  in the case of each Contributor, 
        i.   changes to the Program, and 
        ii.  additions to the Program; 

    where such changes and/or additions to the Program originate from and are
    distributed by that particular Contributor. A Contribution 'originates'
    from a Contributor if it was added to the Program by such Contributor
    itself or anyone acting on such Contributor's behalf. Contributions do not
    include additions to the Program which: (i) are separate modules of 
    software distributed in conjunction with the Program under their own
    license agreement, and (ii) are not derivative works of the Program. 

1.2 "Contributor" means NeuStar and any other entity that distributes the
    Program. 

1.3 "Licensed Patents " mean patent claims licensable by a Contributor which
    are necessarily infringed by the use or sale of its Contribution alone or
    when combined with the Program.
 
1.4 "Original Program" means the original version of the EPP XRI Mapping
    Toolkit software accompanying this Agreement as released by NeuStar,
    including source code, object code and documentation, if any.
 
1.5 "Program" means the Original Program and Contributions. 

1.6 "Recipient" means anyone who receives the Program under this Agreement,
    including all Contributors. 

2. GRANT OF RIGHTS 

2.1 Subject to the terms of this Agreement, each Contributor hereby grants
    Recipient a non-exclusive, worldwide, royalty-free copyright license to
    reproduce, prepare derivative works of, publicly display, publicly
    perform, distribute and sublicense the Contribution of such Contributor,
    if any, and such derivative works, in source code and object code form.
 
2.2 Subject to the terms of this Agreement, each Contributor hereby grants
    Recipient a non-exclusive, worldwide, royalty-free patent license under
    Licensed Patents to make, use, sell, offer to sell, import and otherwise
    transfer the Contribution of such Contributor, if any, in source code
    and object code form. This patent license shall apply to the combination
    of the Contribution and the Program if, at the time the Contribution is
    added by the Contributor, such addition of the Contribution causes such
    combination to be covered by the Licensed Patents. The patent license
    shall not apply to any other combinations which include the Contribution.
    No hardware per se is licensed hereunder. 

2.3 Recipient understands that although each Contributor grants the licenses
    to its Contributions set forth herein, no assurances are provided by any
    Contributor that the Program does not infringe the patent or other
    intellectual property rights of any other entity. Each Contributor
    disclaims any liability to Recipient for claims brought by any other
    entity based on infringement of intellectual property rights or
    otherwise. As a condition to exercising the rights and licenses granted
    hereunder, each Recipient hereby assumes sole responsibility to secure
    any other intellectual property rights needed, if any. For example, if
    a third party patent license is required to allow Recipient to distribute
    the Program, it is Recipient's responsibility to acquire that license
    before distributing the Program. 

2.4 Each Contributor represents that to its knowledge it has sufficient
    copyright rights in its Contribution, if any, to grant the copyright
    license set forth in this Agreement. 

3. REQUIREMENTS 

3.1 A Contributor may choose to distribute the Program in object code form
    under its own license agreement, provided that: 

    a.  it complies with the terms and conditions of this Agreement; and 
    b.  its license agreement:
        i.   effectively disclaims on behalf of all Contributors all warranties
             and conditions, express and implied, including warranties or
             conditions of title and non-infringement, and implied warranties
             or conditions of merchantability and fitness for a particular
             purpose; 
        ii.  effectively excludes on behalf of all Contributors all liability
             for damages, including direct, indirect, special, incidental and
             consequential damages, such as lost profits; 
        iii. states that any provisions which differ from this Agreement are
             offered by that Contributor alone and not by any other party; and 
        iv.  states that source code for the Program is available from such
             Contributor, and informs licensees how to obtain it in a
             reasonable manner on or through a medium customarily used for
             software exchange. 

3.2 When the Program is made available in source code form: 

    a.  it must be made available under this Agreement; and 
    b.  a copy of this Agreement must be included with each copy of the
        Program. 

3.3 Each Contributor must include the following in a conspicuous location in
    the Program: 

        "Copyright (C) 2001-2005 NeuStar, Inc. All Rights Reserved." 

3.4 In addition, each Contributor must identify itself as the originator of
    its Contribution, if any, in a manner that reasonably allows subsequent
    Recipients to identify the originator of the Contribution. 

4. COMMERCIAL DISTRIBUTION 

   Commercial distributors of software may accept certain responsibilities
   with respect to end users, business partners and the like.  While this
   license is intended to facilitate the commercial use of the Program, the 
   Contributor who includes the Program in a commercial product offering
   should do so in a manner which does not create potential liability for
   other Contributors. Therefore, if a Contributor includes the Program in 
   a commercial product offering, such Contributor ("Commercial Contributor")
   hereby agrees to defend and indemnify every other Contributor ("Indemnified
   Contributor") against any losses, damages and costs (collectively "Losses")
   arising from claims, lawsuits and other legal actions brought by a third
   party against the Indemnified Contributor to the extent caused by the acts
   or omissions of such Commercial Contributor in connection with its
   distribution of the Program in a commercial product offering. The 
   obligations in this section do not apply to any claims or Losses relating
   to any actual or alleged intellectual property infringement. In order to
   qualify, an Indemnified Contributor must: a) promptly notify the Commercial
   Contributor in writing of such claim, and b) allow the Commercial
   Contributor to control, and cooperate with the Commercial Contributor in,
   the defense and any related settlement negotiations. The Indemnified 
   Contributor may participate in any such claim at its own expense. 

   For example, a Contributor might include the Program in a commercial
   product offering, Product X. That Contributor is then a Commercial
   Contributor. If that Commercial Contributor then makes performance claims,
   or offers warranties related to Product X, those performance claims and
   warranties are such Commercial Contributor's responsibility alone. Under
   this section, the Commercial Contributor would have to defend claims
   against the other Contributors related to those performance claims and
   warranties, and if a court requires any other Contributor to pay any
   damages as a result, the Commercial Contributor must pay those damages. 

5. NO WARRANTY 

   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON
   AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER 
   EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR
   CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A
   PARTICULAR PURPOSE. Each Recipient is solely responsible for determining
   the appropriateness of using and distributing the Program and assumes all
   risks associated with its exercise of rights under this Agreement,
   including but not limited to the risks and costs of program errors,
   compliance with applicable laws, damage to or loss of data, programs or
   equipment, and unavailability or interruption of operations. 

6. DISCLAIMER OF LIABILITY 

   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY 
   CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, 
   SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT 
   LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, 
   WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR 
   OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM 
   OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE 
   POSSIBILITY OF SUCH DAMAGES. 

7. GENERAL 

   If any provision of this Agreement is invalid or unenforceable under
   applicable law, it shall not affect the validity or enforceability of the
   remainder of the terms of this Agreement, and without further action by
   the parties hereto, such provision shall be reformed to the minimum extent
   necessary to make such provision valid and enforceable. 

   If Recipient institutes patent litigation against a Contributor with respect
   to a patent applicable to software (including a cross-claim or counterclaim
   in a lawsuit), then any patent licenses granted by that Contributor to such
   Recipient under this Agreement shall terminate as of the date such
   litigation is filed. In addition, if Recipient institutes patent litigation
   against any entity (including a cross-claim or counterclaim in a lawsuit)
   alleging that the Program itself (excluding combinations of the Program
   with other software or hardware) infringes such Recipient's patent(s), then
   such Recipient's rights granted under Section 2(b) shall terminate as of
   the date such litigation is filed. 

   All Recipient's rights under this Agreement shall terminate if it fails to
   comply with any of the material terms or conditions of this Agreement and
   does not cure such failure in a reasonable period of time after becoming
   aware of such noncompliance. If all Recipient's rights under this Agreement
   terminate, Recipient agrees to cease use and distribution of the Program as
   soon as reasonably practicable. However, Recipient's obligations under this
   Agreement and any licenses granted by Recipient relating to the Program
   shall continue and survive. 

   NeuStar may publish new versions (including revisions) of this Agreement
   from time to time. Each new version of the Agreement will be given a
   distinguishing version number. The Program (including Contributions) may
   always be distributed subject to the version of the Agreement under which
   it was received. In addition, after a new version of the Agreement is
   published, Contributor may elect to distribute the Program (including its
   Contributions) under the new version. No one other than NeuStar has the
   right to modify this Agreement. Except as expressly stated in Sections
   2(a) and 2(b) above, Recipient receives no rights or licenses to the
   intellectual property of any Contributor under this Agreement, whether 
   expressly, by implication, estoppel or otherwise. All rights in the
   Program not expressly granted under this Agreement are reserved. 

   This Agreement is governed by the laws of the Commonwealth of Virginia and
   the intellectual property laws of the United States of America. No party
   to this Agreement will bring a legal action under this Agreement more than
   one year after the cause of action arose. Each party waives its rights to
   a jury trial in any resulting litigation.
