+ModSecurity Licensing Exception
+
+Version 1.0 draft 5, 18 June 2008
+
+As a special exception ("Exception") to the terms and conditions of version 2 of the
+GPL, Breach Security, Inc. hereby grants you the rights described below, provided
+you agree to the terms and conditions in this Exception, including its obligations and
+restrictions on use.
+
+Exception Intent
+
+We want specified Free/Libre and Open Source Software ("FLOSS") programs to be
+able to use ModSecurity (the "Program") despite the fact that not all FLOSS licenses
+are compatible with version 2 of the GNU General Public License (the "GPLv2").
+
+Legal Terms and Conditions
+
+You are free to distribute a Derivative Work that is formed entirely from the Program
+and one or more works (each, a "FLOSS Work") licensed under one or more of the
+licenses listed below in section 1, as long as all of the following conditions are met:
+
+1. You obey the GPLv2 in all respects for the Program and the Derivative Work,
+   except for identifiable sections of the Derivative Work which are
+
+   1. not derived from the Program, and
+
+   2. are not designed to interact with the Program, and
+
+   3. which can reasonably be considered independent and separate works in
+      themselves.
+
+2. All such identifiable sections of the Derivative Work are
+
+   1. distributed subject to one of the FLOSS licenses listed below, and
+
+   2. the object code or executable form of those sections are accompanied
+      by the complete corresponding machine-readable source code for those
+      sections on the same medium and under the same FLOSS license as the
+      corresponding object code or executable forms of those sections.
+
+3. Any works which are aggregated with the Program or with a Derivative Work
+   on a volume of a storage or distribution medium in accordance with the
+   GPLv2, can reasonably be considered independent and separate works in
+   themselves which are not derivatives of either the Program, a Derivative Work
+   or a FLOSS Work, and are not designed to interact with the Program.
+
+If the above conditions are not met, then the Program may only be copied, modified,
+distributed or used under the terms and conditions of the GPLv2 or another valid
+licensing option from Breach Security, Inc.

+
+Due to the many variants of some of the above licenses, we require that for any
+version of the listed FLOSS licenses to qualify under this exception, it must follow
+the 2003 version of the Free Software Foundation's Free Software Definition
+(http://www.gnu.org/philosophy/free-sw.html) or version 1.9 of the Open Source
+Definition by the Open Source Initiative
+(http://www.opensource.org/docs/definition.php).
+
+
+2. Definitions
+
+   1. Terms used, but not defined, herein shall have the meaning provided in the
+      version 2 of the GPL.
+
+   2. Derivative Work means a derivative work under copyright law.
+
+
+3. Applicability
+
+This Exception applies to all Programs that contain a notice placed by Breach
+Security, Inc. saying that the Program may be distributed under the terms of this
+Exception. If you create or distribute a work which is a Derivative Work of both the
+Program and any other work licensed under the GPL, then this FLOSS Exception is
+not available for that work; thus, you must remove the FLOSS Exception notice from
+that work and comply with the GPL in all respects, including by retaining all GPL
+notices.
+
+You may choose to redistribute a copy of the Program exclusively under the terms of
+the GPLv2 by removing the Exception notice from that copy of the Program, provided
+that the copy has never been modified by you or any third party.
+
+
+Appendix A. Qualified Libraries and Packages
+
+The following is a non-exhaustive list of libraries and packages which are covered by
+the Exception when they are licensed under one or more of the licenses listed above.
+Please note that this appendix is merely provided as an additional service to specific
+FLOSS projects who wish to simplify licensing information for their users.
+Compliance with one of the licenses noted under the "FLOSS license list" section
+remains a prerequisite.
