   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

          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: GSC-17798-1, Version 0.5 and entitled Perl 6 GraphQL,

          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

           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



                                   2
          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  2016 United States Government as represented by the
          Administrator of the National Aeronautics and Space Administration.
          No copyright is claimed in the United States under Title 17, U.S.Code.
          All Other 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




                                    3
     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: http://opensource.gsfc.nasa.gov. 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 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



                               4
          represents that a license shall not be required nor that, if required, it
          shall be issued. Nothing granted herein provides any such export
          license.

   INDEMNIFICATION

          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
