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,

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.

G. “Original Software” means the computer software first released under
this Agreement by Government Agency with Government Agency designation
NASA Ames Research Center and entitled ATD-2 Machine Learning Airport
Surface Model: Unimpeded Taxi In, including source code,
object code and accompanying documentation, if any.

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 2021 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 provide Government Agency, by e-mail to the Government
Agency Point of Contact listed in clause 5.F., the following
information: name and email. 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, by e-mail to the Government Agency Point of Contact
listed in clause 5.F., how to access the Modification.

G. Each Contributor represents that 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.

AGAINST THE UNITED STATES GOVERNMENT, ITS CONTRACTORS AND

PRODUCTS BASED ON, OR RESULTING FROM, RECIPIENT'S USE OF THE SUBJECT
SOFTWARE, RECIPIENT SHALL INDEMNIFY AND HOLD HARMLESS THE UNITED STATES
GOVERNMENT, ITS CONTRACTORS AND SUBCONTRACTORS, AS WELL AS ANY PRIOR
