LICENCE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
OF RISC OS AND ITS DERIVATIVES
This licence agreement ("Licence") is between Castle Technology Limited
("Castle") and any person ("You", "Your") who exercises any of the legal
rights over any components of the computer operating system known as
RISC OS granted by Castle in this Licence. The phrase "RISC OS" used in
this Licence refers to those components of version 5.0 of RISC OS that
Castle chooses to release from time to time and any subsequent release of
RISC OS which is made generally available by Castle pursuant to this
Licence. The phrase "Derivative Work" means any derivative work which is
based on, or derived from, RISC OS or any part of RISC OS (whether by
modification or translation) and any work subsequently derived from such
Derivative Work or any part of it PROVIDED THAT such work is only intended
to be used in conjunction with an embodiment (whether physical or emulated)
of one or more versions of the ARM processor architecture. By exercising
any of the rights granted to You by Castle pursuant to this Licence You
indicate Your acceptance of all of the terms and conditions of this Licence
which shall therefore be legally binding on You.
1 LICENCE GRANT
1.1 Subject to the restrictions set out in the remainder of this Licence
Castle hereby grants to You a non-exclusive royalty free worldwide licence
to use, copy and distribute the RISC OS source code and object code in any
medium PROVIDED THAT you ensure that each copy You distribute incorporates
the text of, or an Internet link to, this Licence.
1.2 You may modify your copy of RISC OS or any part of it (and any Derivative
Work or any part of it) to create a Derivative Work and You may copy and
distribute the source code and object code of such Derivative Work in any
medium PROVIDED THAT you meet all of the following conditions:
1.2.1 You shall ensure that each Derivative Work You distribute carries a
notice stating that it is ultimately derived from RISC OS and the date of
Your modifications;
1.2.2 You shall ensure that each Derivative Work You distribute as source
code prominently carries the following header text in each individual source
code file:

1.2.3 You shall ensure that each Derivative Work distributed by You is
distributed and licensed in its entirety at no charge on the terms of this
Licence to any third party who is prepared to accept the terms of this Licence.

considered an independent and separate work then this Licence shall not apply
to any such part where You distribute such part as an independent and separate
work;
1.2.4 You undertake, in respect of each Derivative Work that You distribute,
to make the whole source code of every individual component of the Derivative
Work available for unrestricted access by third parties by including a copy of
the source code with Your distribution and/or by uploading the source code to
the official RISC OS source code repository at
www.riscosopen.org/content/sources
1.2.5 You hereby grant to Castle a royalty free worldwide licence (with the
right to grant sub-licences) to incorporate into RISC OS or any Derivative
Work produced by Castle, the whole or any part of any Derivative Work which
You create or distribute pursuant to this Licence. You acknowledge that
Castle may make the whole or any part of RISC OS or any Derivative Work
produced by Castle available to OEM organisations on commercial terms for
incorporation into hardware products intended for sale. Your hereby waive any
moral rights You may have in any part of any Derivative Work which Castle
so incorporates into RISC OS or any Derivative Work produced by Castle.
Nothing in this Clause 1.2.5 shall oblige Castle to incorporate into
RISC OS or any Derivative Work produced by Castle any part of any Derivative
Work which You create or distribute pursuant to this Licence.
2 LICENCE RESTRICTIONS
2.1 You may not copy, modify, sublicense or distribute RISC OS or any
Derivative Work except as expressly provided under this Licence. Any attempt
by You otherwise to copy, modify, sublicense or distribute RISC OS or any
Derivative Work shall be void and shall lead to the automatic termination
of Your rights under this Licence but such termination shall not affect the
rights of any person to whom You have distributed RISC OS or any Derivative
Work provided they continue to comply with the terms and conditions of this
Licence.
2.2 You may not impose on any third party to whom You have distributed copies
of RISC OS or any Derivative Work any licence restrictions other than those
set out in this Licence.
2.3 If, as a consequence of any court judgment, allegation of infringement of
any proprietary right or any other reason You are unable to comply fully with
the terms and conditions of this Licence then You shall refrain from
distributing RISC OS or such Derivative Works (as appropriate) for the
duration of such non-compliance.
2.4 This Licence is not an OEM licence. Consequently, You may not incorporate
or embed RISC OS or any Derivative Work or any part of them in any hardware
product which is intended for commercial sale, nor may You distribute, sell,
supply or otherwise dispose of any such hardware product unless You have
obtained the prior written consent of Castle. Castle is generally prepared
to grant OEM licences on commercial terms to any person who wishes to
incorporate or embed RISC OS or any Derivative Work or any part of them into
a hardware product and/or to sell, supply or otherwise dispose of such
hardware products. Details of Castle's standard OEM licensing terms are

PARTY PROPRIETARY RIGHTS. ALL IMPLIED WARRANTIES AND CONDITIONS ARE
EXCLUDED TO THE EXTENT PERMITTED BY LAW.
