<h3><a name="Exception_Intent"></a>Exception Intent</h3>
      
<p>Our aim is for Free/Libre and Open Source Software
        (&quot;FLOSS&quot;) applications to be able to use specified GPL-licensed
        Silverpeas software (the &quot;Program&quot;) despite the fact that not all FLOSS
        licenses are compatible with version 3 of the GNU Affero General
        Public License (the &quot;GPL&quot;).
      </p>
      </section>
      <section>
<h3><a name="Legal_Terms_and_Conditions"></a>Legal Terms and Conditions</h3>
      
<p>As a special exception to the terms and conditions of version 3.0 of the GPL:</p>
      
<p>You are free to distribute a Derivative Work that is
        formed entirely from the Program and one or more works (each, a &quot;FLOSS
        Work&quot;) licensed under one or more of the licenses listed below in
        section 1, as long as:
      </p>
      
<ol style="list-style-type: decimal">
        
<li>You obey the GPL in all respects for the Program and
          the Derivative Work, except for identifiable sections of the Derivative
          Work which are not derived from the Program, and which can reasonably
          be considered independent and separate works in themselves,
        </li>
        
<li>all identifiable sections of the Derivative Work which
          are not derived from the Program, and which can reasonably be
          considered independent and separate works in themselves,
        </li>
        
<li>
          
<ol style="list-style-type: decimal">
            
<li>are distributed subject to one of the FLOSS licenses listed below, and</li>
            
<li>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, and
            </li>
          </ol>
        </li>
        
<li>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 GPL, 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.
        </li>
      </ol>
      
<p>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 GPL or another valid licensing option from
        Silverpeas.

<p align="left">This FLOSS Exception applies to all Programs
          that contain a notice placed by Silverpeas saying that the Program may
          be distributed under the terms of this FLOSS 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 GPL by removing
          the FLOSS Exception notice from that copy of the Program, provided
          that the copy has never been modified by you or any third party.
