               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:

            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

            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.

    2. 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 (C) 2006-2010 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:
               http://opensource.arc.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 represents that a
               license shall not be required nor that, if required, it shall
               be issued.  Nothing granted herein provides any such export
               license.

    3. DISCLAIMER OF WARRANTIES AND LIABILITIES; WAIVER AND INDEMNIFICATION

            A. No Warranty: THE SUBJECT SOFTWARE IS PROVIDED "AS IS" WITHOUT
               ANY WARRANTY OF ANY KIND, EITHER EXPRESSED, IMPLIED, OR
               STATUTORY, INCLUDING, BUT 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 INFRINGEMENT, ANY
               WARRANTY THAT THE SUBJECT SOFTWARE WILL BE ERROR FREE, OR ANY
               WARRANTY 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 RESULTS, RESULTING DESIGNS, HARDWARE,
               SOFTWARE 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.
