1. DEFINITIONS

A.	"Contributor" means Government Agency, as the developer of the 
         Original Software, and any entity that makes a Modification.

B. 	"Covered Patents" mean patent claims licensable by a Contributor 
         that are necessarily infringed by the use or sale of its Modification
         alone or when combined with the Subject Software.

C. 	"Display" means the showing of a copy of the Subject Software, either
         directly or by means of an image, or any other device.

D. 	"Distribution" means conveyance or transfer of the Subject Software, 
         regardless of means, to another.

         that is not governed by the terms of this Agreement.

F.  	"Modification" means any alteration of, including addition to or deletion 
         from, the substance or structure of either the Original Software or Subject 
         Software, and includes derivative works, as that term is defined in the
         Copyright Statute, 17 USC 101.  However, the act of including Subject 
         Software as part of a Larger Work does not in and of itself constitute
         a Modification.

         released under this Agreement by Government Agency with Government
         Agency designation GSC-15,132-1, with title identified herein,

         for any purpose.


2. GRANT OF RIGHTS

A.	 Under Non-Patent Rights: Subject to the terms and conditions of
         this Agreement, each Contributor, with respect to its own contribution
         to the Subject Software, hereby grants to each Recipient a non-exclusive,
         world-wide, royalty-free license to engage in the following activities
         pertaining to the Subject Software:

1. Use
2. Distribution
3. Reproduction
4. Modification
5. Redistribution
6. Display

B. 	Under Patent Rights: Subject to the terms and conditions of this Agreement,
        each Contributor, with respect to its own contribution to the Subject Software,
        hereby grants to each Recipient under Covered Patents a non-exclusive,
        world-wide, royalty-free license to engage in the following activities
        pertaining to the Subject Software:

1. Use
2. Distribution
3. Reproduction
4. Sale
5. Offer for Sale

C.     The rights granted under Paragraph B. also apply to the combination of
       a Contributor's Modification and the Subject Software if, at the time the
       Modification is added by the Contributor, the addition of such Modification
       causes the combination to be covered by the Covered Patents.  It does not
       apply to any other combinations that include a Modification.

D. 	The rights granted in Paragraphs A. and B. allow the Recipient to 
        sublicense those same rights.  Such sublicense must be under the same
        terms and conditions of this Agreement.


3. OBLIGATIONS OF RECIPIENT

A. 	Distribution or Redistribution of the Subject Software must be made under
        this Agreement except for additions covered under paragraph 3H.

1. 	Whenever a Recipient distributes or redistributes the Subject Software,
        a copy of this Agreement must be included with each copy of the Subject
        Software; and

2. 	If Recipient distributes or redistributes the Subject Software in any 
        form other than source code, Recipient must also make the source code freely
        available, and must provide with each copy of the Subject Software information
        on how to obtain the source code in a reasonable manner on or through a medium
        customarily used for software exchange.

B.	 Each Recipient must ensure that the following copyright notice appears
         prominently in the Subject Software:

         Copyright 2002-2007 United States Government as represented by the Administrator
         of The National Aeronautics and Space Administration. All Rights Reserved.

C.	 Each Contributor must characterize its alteration of the Subject Software
         as a Modification and must identify itself as the originator of its Modification
         in a manner that reasonably allows subsequent Recipients to identify the originator
         of the Modification.  In fulfillment of these requirements, Contributor must
         include a file (e.g., a change log file) that describes the alterations made
         and the date of the alterations, identifies Contributor as originator of the
         alterations, and consents to characterization of the alterations as a Modification,
         for example, by including a statement that the Modification is derived, directly
         or indirectly, from Original Software provided by Government Agency. Once consent
         is granted, it may not thereafter be revoked.

D. 	A Contributor may add its own copyright notice to the Subject Software. 
        Once a copyright notice has been added to the Subject Software, a Recipient
        may not remove it without the express permission of the Contributor who added
        the notice.

E. 	A Recipient may not make any representation in the Subject Software or
        in any promotional, advertising or other material that may be construed
        as an endorsement by Government Agency or by any prior Recipient of any product
        or service provided by Recipient, or that may seek to obtain commercial
        advantage by the fact of Government Agency's or a prior Recipient's 
        participation in this Agreement.

F. 	In an effort to track usage and maintain accurate records of the Subject 
        Software, each Recipient, upon receipt of the Subject Software, is requested to
        register with Government Agency by visiting the following website:	
        .  Recipient's name and personal information shall be used for statistical
        purposes only. Once a Recipient makes a Modification available, it is 
        requested that the Recipient inform Government Agency at the web site
        provided above how to access the Modification.

G. 	Each Contributor represents that its Modification is believed to be Contributor's
        original creation and does not violate any existing agreements, regulations,
        statutes or rules, and further that Contributor has sufficient rights to
        grant the rights conveyed by this Agreement.

H. 	A Recipient may choose to offer, and to charge a fee for, warranty, support,
        indemnity and/or liability obligations to one or more other Recipients of
         the Subject Software.  A Recipient may do so, however, only on its own behalf
        and not on behalf of Government Agency or any other Recipient.  Such a
        Recipient must make it absolutely clear that any such warranty, support,
        indemnity and/or liability obligation is offered by that Recipient alone.  
         Further, such Recipient agrees to indemnify Government Agency and every 
         other Recipient for any liability incurred by them as a result of warranty,
        support, indemnity and/or liability offered by such Recipient.

I. 	A Recipient may create a Larger Work by combining Subject Software with
        separate software not governed by the terms of this agreement and distribute
        the Larger Work as a single product. In such case, the Recipient must make
        sure Subject Software, or portions thereof, included in the Larger Work
        is subject to this Agreement.

J. 	Notwithstanding any provisions contained herein, Recipient is hereby put
        on notice that export of any goods or technical data from the United States
        may require some form of export license from the U.S. Government.  Failure
        to obtain necessary export licenses may result in criminal liability under U.S. laws.
        Government Agency neither represents that a license shall not be required
        nor that, if required, it shall be issued.  Nothing granted herein provides
        any such export license.
