   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 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.

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

     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:

          BASSHFS: BashAccessible SSH File System
          Copyright (C) 2019 United States Government as represented by the
          Administrator of the National Aeronautics and Space Administration.
          All Rights Reserved.

          BASSHFS: Bash-Accessible SSH File System contains 3rd party code.
          Copyright notices for 3rd party code below. The license can be found
          at https://dev.perl.org/licenses/artistic.html.

          _glob_to_regex method based on code (c) 2002 Richard Clamp.

     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.

4. DISCLAIMER OF WARRANTIES AND LIABILITIES; WAIVER AND
   INDEMNIFICATION

     A.   No Warranty: THE SUBJECT SOFTWARE IS PROVIDED "AS IS"

          NOT LIMITED TO, ANY WARRANTY THAT THE SUBJECT
          SOFTWARE WILL CONFORM TO SPECIFICATIONS, ANY
          IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS
          FOR A PARTICULAR PURPOSE, OR FREEDOM FROM

          THAT DOCUMENTATION, IF PROVIDED, WILL CONFORM TO
          THE SUBJECT SOFTWARE. THIS AGREEMENT DOES NOT, IN
          ANY MANNER, CONSTITUTE AN ENDORSEMENT BY
          GOVERNMENT AGENCY OR ANY PRIOR RECIPIENT OF ANY

          PRODUCTS OR ANY OTHER APPLICATIONS RESULTING
          FROM USE OF THE SUBJECT SOFTWARE. FURTHER,
          GOVERNMENT AGENCY DISCLAIMS ALL WARRANTIES AND
          LIABILITIES REGARDING THIRD-PARTY SOFTWARE, IF
          PRESENT IN THE 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 LIABILITIES, DEMANDS, DAMAGES, EXPENSES OR
          LOSSES ARISING FROM SUCH USE, 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 RECIPIENT, TO
          THE EXTENT PERMITTED BY LAW. RECIPIENT'S SOLE
          REMEDY FOR ANY SUCH MATTER SHALL BE THE
          IMMEDIATE, UNILATERAL TERMINATION OF THIS
          AGREEMENT.

5. GENERAL TERMS

     A.   Termination: This Agreement and the rights granted hereunder will

          days of becoming aware of such noncompliance. Upon termination, a
          Recipient agrees to immediately cease use and distribution of the
          Subject Software. All sublicenses to the Subject Software properly
          granted by the breaching Recipient shall survive any such termination
          of this Agreement.
