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

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 2012 United States Government as represented by Christopher
E. Kees. 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
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: https://proteus.usace.army.mil/reg. 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.
