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.

E. “Larger Work” means computer software that combines Subject
Software, or portions thereof, with software separate from the Subject
Software 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.

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 Ocean
Worlds Autonomy Testbed for Exploration Research and Simulation
(OceanWATERS), including source code, object code and
accompanying documentation, if any.

H. “Recipient” means anyone who acquires the Subject Software under
this Agreement, including all Contributors.

I. “Redistribution” means Distribution of the Subject Software after a
Modification has been made.

J. “Reproduction” means the making of a counterpart, image or copy of
the Subject Software.

K. “Sale” means the exchange of the Subject Software for money or
equivalent value.

L. “Subject Software” means the Original Software, Modifications, or
any respective parts thereof.

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

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 © 2020 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.

ORIGINAL SOFTWARE, AND DISTRIBUTES IT “AS IS.”

B. Waiver and Indemnity: RECIPIENT AGREES TO WAIVE ANY AND ALL CLAIMS AGAINST
THE UNITED STATES GOVERNMENT, ITS CONTRACTORS AND SUBCONTRACTORS, AS WELL AS ANY
PRIOR RECIPIENT. IF RECIPIENT'S USE OF THE SUBJECT SOFTWARE RESULTS IN ANY

INCLUDING ANY DAMAGES FROM 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
