BENEFICIARY OF ALL SUBSEQUENT DISTRIBUTIONS OR REDISTRIBUTIONS 
OF THE SUBJECT SOFTWARE. ANYONE WHO USES, REPRODUCES, DISTRIBUTES,

________________________________________________


1. DEFINITIONS

A. "Contributor" means NMDP, as the developer of the Original Software,
   NIH, 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

   act of including Subject Software as part of a Larger Work does not
   in and of itself constitute a Modification.

   (Perl ECS), including source code, object code and accompanying
   documentation, if any.

   Covered Patents. It does not apply to any other combinations that
   include a Modification.

D. The rights granted in Paragraphs 2.A. and 2.B., above, 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
   3.H.

   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) 2002-2025 National Marrow Donor Program. 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 NMDP. 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 NMDP, NIH, 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 NMDP's, NIH'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 NMDP, by e-mail to the NMDP Point
   of Contact listed in paragraph 5.F., the following information:
   Organization name, contact information, description of intended use.
   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 NMDP, by e-mail
   to the NMDP Point of Contact listed in paragraph 5.F., how to access
   the Modification.

G. Each Contributor represents 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 NMDP, NIH, 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 NMDP, NIH, 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
   United States Government. Failure to obtain necessary export
   licenses may result in criminal liability under U.S. laws. NMDP and
   NIH neither represent 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" 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 NMDP, NIH, OR ANY PRIOR RECIPIENT OF
   ANY RESULTS, RESULTING DESIGNS, HARDWARE, SOFTWARE PRODUCTS OR ANY
   OTHER APPLICATIONS RESULTING FROM USE OF THE SUBJECT SOFTWARE.
   FURTHER, NMDP 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 NMDP, 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
   NMDP, 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.

   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.

B. Severability: If any provision of this Agreement is invalid or
   unenforceable under applicable law, it shall not affect the validity
   or enforceability of the remainder of the terms of this Agreement.

   federal law only for all purposes, including, but not limited to,

   understanding and agreement of the parties relating to release of
   the Subject Software and may not be superseded, modified or amended
