Linden Research, Inc. ("Linden Lab") Viewer FLOSS License Exception v0.5
The Linden Lab Exception for Free/Libre and Open Source Software-only
Applications Using Linden Lab Viewer Software (the "FLOSS Exception").
Exception Intent
Linden Lab is releasing the source code for certain software that
enables users to view or otherwise access the Second Life virtual
world environment (the "Viewer Software"), under version 2 of the GNU
General Public License (the "GPL"). The creation or distribution of
works based on the Program (as defined under the GPL) of the Viewer
Software may require the use of certain Free/Libre and Open Source
Software ("FLOSS") works that are subject to license agreements not
compatible with re-licensing under the GPL. Because we want to allow
the Viewer Software to be distributed with these FLOSS works, this
FLOSS Exception following exception applies subject to the terms and
conditions below.
Legal Terms and Conditions
As a special exception to the terms and conditions of version 2.0 of
the GPL:
You are free to distribute a work based on the Program that is formed
entirely from the Viewer Software (and any modifications thereof) and
one or more works that are independent and separate works not derived
from the Viewer Software, and are licensed under one or more of the
licenses listed below in section 1 (each, a "FLOSS Work") , as long
A. You obey the GPL in all respects for the Viewer Software and any
work based on the Program, except for the FLOSS Works, for which
you must comply with B below,
B. all FLOSS Works,
i. are distributed subject to one of the FLOSS licenses
listed below, and
ii. the object code or executable form of the FLOSS Works are
accompanied by the complete corresponding
machine-readable source code for those FLOSS Works on the
same medium and under the same FLOSS license as the
corresponding object code or executable forms thereof,
C. any works that are aggregated with the Viewer Software or a work
based on the Program on a volume of a storage or distribution
medium in accordance with the GPL, and are not licensed under
the FLOSS licenses listed below, are independent and separate
works in themselves which are not derivatives of either the
Viewer Software, a work based on the Program or a FLOSS Work.
If the above conditions are not met, then the Viewer Software may only
be copied, modified, distributed or used under the terms and
conditions of the GPL or another valid licensing option from Linden

the GPL.
3. Applicability
This FLOSS Exception applies to all Viewer Software files that contain
a notice placed by Linden Lab saying that the Viewer Software may be
distributed under the terms of this FLOSS Exception. If you create or
distribute a work which is a work based on the Program for the Viewer
Software 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 Viewer Software exclusively under the terms
of the GPL by removing the FLOSS Exception notice from that copy of
the Viewer Software, provided that the copy has never been modified by
you or any third party.
