<p>COPYING file for VirtualBox versions 7.0 and later versions
that include this file</p>

<p>Preliminary notes:</p>

<p style='text-align:justify'>1) The majority of the code in
the VirtualBox base package is licensed under the GNU General Public License,
version 3 (GPL). VirtualBox contains many components developed by Oracle and
various third parties. The license for each component is located in the
licensing documentation and/or in the component's source code.</p>

<p style='text-align:justify'>2) As an exception to the reciprocal
license obligations of the GPL listed below, you may use any VirtualBox header
file that is marked by Oracle as licensed under both the GPL and the Common
Development and Distribution License version 1.0 (CDDL) to invoke the
unmodified VirtualBox libraries. In other words, calling such a multi-licensed
interface by dynamically linking to the unmodified VirtualBox libraries is
considered a normal use of VirtualBox and does not turn the calling code into a
derived work of VirtualBox. In particular, this applies to code that wants to
extend VirtualBox by way of the Extension Pack mechanism declared in the
ExtPack.h header file.</p>

<p style='text-align:justify'>3) Whoever creates or distributes
a derived work based on VirtualBox is not obligated to grant the above
exceptions for such a version. The GPL permits you to release a modified
version without the above exception; in addition, Oracle hereby also allows you
to release a modified version which carries forward these exceptions.</p>

<p>Oracle America, Inc.</p>

<p>GNU GENERAL PUBLIC LICENSE</p>

<p>Version 3, 29 June 2007</p>

<p>Copyright &copy; 2007 Free Software Foundation, Inc.
&lt;https://fsf.org/&gt;</p>

<p style='text-align:justify'>Everyone is permitted to copy and
distribute verbatim copies of this license document, but changing it is not
allowed.</p>

<p>Preamble</p>

<p>The GNU General Public License is a free, copyleft license
for software and other kinds of works.</p>

<p style='text-align:justify'>The licenses for most software
and other practical works are designed to take away your freedom to share and
change the works. By contrast, the GNU General Public License is intended to
guarantee your freedom to share and change all versions of a program--to make
sure it remains free software for all its users. We, the Free Software
Foundation, use the GNU General Public License for most of our software; it
applies also to any other work released this way by its authors. You can apply
it to your programs, too.</p>

<p style='text-align:justify'>When we speak of free software,
we are referring to freedom, not price. Our General Public Licenses are
designed to make sure that you have the freedom to distribute copies of free
software (and charge for them if you wish), that you receive source code or can
get it if you want it, that you can change the software or use pieces of it in
new free programs, and that you know you can do these things.</p>

<p style='text-align:justify'>To protect your rights, we need
to prevent others from denying you these rights or asking you to surrender the
rights. Therefore, you have certain responsibilities if you distribute copies
of the software, or if you modify it: responsibilities to respect the freedom
of others.</p>

<p style='text-align:justify'>For example, if you distribute
copies of such a program, whether gratis or for a fee, you must pass on to the
recipients the same freedoms that you received. You must make sure that they,
too, receive or can get the source code. And you must show them these terms so
they know their rights.</p>

<p style='text-align:justify'>Developers that use the GNU GPL
protect your rights with two steps: (1) assert copyright on the software, and
(2) offer you this License giving you legal permission to copy, distribute
and/or modify it.</p>

<p style='text-align:justify'>For the developers' and authors'
protection, the GPL clearly explains that there is no warranty for this free
software. For both users' and authors' sake, the GPL requires that modified
versions be marked as changed, so that their problems will not be attributed
erroneously to authors of previous versions.</p>

<p style='text-align:justify'>Some devices are designed to deny
users access to install or run modified versions of the software inside them,
although the manufacturer can do so. This is fundamentally incompatible with
the aim of protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to use,
which is precisely where it is most unacceptable. Therefore, we have designed
this version of the GPL to prohibit the practice for those products. If such
problems arise substantially in other domains, we stand ready to extend this
provision to those domains in future versions of the GPL, as needed to protect
the freedom of users.</p>

<p style='text-align:justify'>Finally, every program is
threatened constantly by software patents. States should not allow patents to
restrict development and use of software on general-purpose computers, but in
those that do, we wish to avoid the special danger that patents applied to a
free program could make it effectively proprietary. To prevent this, the GPL
assures that patents cannot be used to render the program non-free.</p>

<p style='text-align:justify'>The precise terms and conditions
for copying, distribution and modification follow.</p>

<p style='text-align:justify'>TERMS AND CONDITIONS</p>

<p style='text-align:justify'>0. Definitions.</p>

<p style='text-align:justify'>&ldquo;This License&rdquo; refers to version
3 of the GNU General Public License.</p>

<p style='text-align:justify'>&ldquo;Copyright&rdquo; also means
copyright-like laws that apply to other kinds of works, such as semiconductor
masks.</p>

<p style='text-align:justify'>&ldquo;The Program&rdquo; refers to any
copyrightable work licensed under this License. Each licensee is addressed as
&ldquo;you&rdquo;. &ldquo;Licensees&rdquo; and &ldquo;recipients&rdquo; may be individuals or organizations.</p>

<p style='text-align:justify'>To &ldquo;modify&rdquo; a work means to copy
from or adapt all or part of the work in a fashion requiring copyright
permission, other than the making of an exact copy. The resulting work is
called a &ldquo;modified version&rdquo; of the earlier work or a work &ldquo;based on&rdquo; the
earlier work.</p>

<p style='text-align:justify'>A &ldquo;covered work&rdquo; means either the
unmodified Program or a work based on the Program.</p>

<p style='text-align:justify'>To &ldquo;propagate&rdquo; a work means to do
anything with it that, without permission, would make you directly or
secondarily liable for infringement under applicable copyright law, except
executing it on a computer or modifying a private copy. Propagation includes
copying, distribution (with or without modification), making available to the
public, and in some countries other activities as well.</p>

<p style='text-align:justify'>To &ldquo;convey&rdquo; a work means any kind
of propagation that enables other parties to make or receive copies. Mere
interaction with a user through a computer network, with no transfer of a copy,
is not conveying.</p>

<p style='text-align:justify'>An interactive user interface
displays &ldquo;Appropriate Legal Notices&rdquo; to the extent that it includes a
convenient and prominently visible feature that (1) displays an appropriate
copyright notice, and (2) tells the user that there is no warranty for the work
(except to the extent that warranties are provided), that licensees may convey
the work under this License, and how to view a copy of this License. If the
interface presents a list of user commands or options, such as a menu, a
prominent item in the list meets this criterion.</p>

<p style='text-align:justify'>1. Source Code.</p>

<p style='text-align:justify'>The &ldquo;source code&rdquo; for a work
means the preferred form of the work for making modifications to it. &ldquo;Object
code&rdquo; means any non-source form of a work.</p>

<p style='text-align:justify'>A &ldquo;Standard Interface&rdquo; means an
interface that either is an official standard defined by a recognized standards
body, or, in the case of interfaces specified for a particular programming
language, one that is widely used among developers working in that language.</p>

<p style='text-align:justify'>The &ldquo;System Libraries&rdquo; of an
executable work include anything, other than the work as a whole, that (a) is
included in the normal form of packaging a Major Component, but which is not
part of that Major Component, and (b) serves only to enable use of the work
with that Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A &ldquo;Major
Component&rdquo;, in this context, means a major essential component (kernel, window
system, and so on) of the specific operating system (if any) on which the
executable work runs, or a compiler used to produce the work, or an object code
interpreter used to run it.</p>

<p style='text-align:justify'>The &ldquo;Corresponding Source&rdquo; for a
work in object code form means all the source code needed to generate, install,
and (for an executable work) run the object code and to modify the work,
including scripts to control those activities. However, it does not include the
work's System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but which are
not part of the work. For example, Corresponding Source includes interface
definition files associated with source files for the work, and the source code
for shared libraries and dynamically linked subprograms that the work is
specifically designed to require, such as by intimate data communication or
control flow between those subprograms and other parts of the work.</p>

<p style='text-align:justify'>The Corresponding Source need not
include anything that users can regenerate automatically from other parts of
the Corresponding Source.</p>

<p style='text-align:justify'>The Corresponding Source for a
work in source code form is that same work.</p>

<p style='text-align:justify'>2. Basic Permissions.</p>

<p style='text-align:justify'>All rights granted under this
License are granted for the term of copyright on the Program, and are irrevocable
provided the stated conditions are met. This License explicitly affirms your
unlimited permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its content,
constitutes a covered work. This License acknowledges your rights of fair use
or other equivalent, as provided by copyright law.</p>

<p style='text-align:justify'>You may make, run and propagate
covered works that you do not convey, without conditions so long as your
license otherwise remains in force. You may convey covered works to others for
the sole purpose of having them make modifications exclusively for you, or
provide you with facilities for running those works, provided that you comply
with the terms of this License in conveying all material for which you do not
control copyright. Those thus making or running the covered works for you must
do so exclusively on your behalf, under your direction and control, on terms
that prohibit them from making any copies of your copyrighted material outside
their relationship with you.</p>

<p style='text-align:justify'>Conveying under any other
circumstances is permitted solely under the conditions stated below.
Sublicensing is not allowed; section 10 makes it unnecessary.</p>

<p style='text-align:justify'>3. Protecting Users' Legal Rights
From Anti-Circumvention Law.</p>

<p style='text-align:justify'>No covered work shall be deemed
part of an effective technological measure under any applicable law fulfilling
obligations under article 11 of the WIPO copyright treaty adopted on 20
December 1996, or similar laws prohibiting or restricting circumvention of such
measures.</p>

<p style='text-align:justify'>When you convey a covered work,
you waive any legal power to forbid circumvention of technological measures to
the extent such circumvention is effected by exercising rights under this
License with respect to the covered work, and you disclaim any intention to
limit operation or modification of the work as a means of enforcing, against
the work's users, your or third parties' legal rights to forbid circumvention
of technological measures.</p>

<p style='text-align:justify'>4. Conveying Verbatim Copies.</p>

<p style='text-align:justify'>You may convey verbatim copies of
the Program's source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate copyright
notice; keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code; keep
intact all notices of the absence of any warranty; and give all recipients a
copy of this License along with the Program.</p>

<p style='text-align:justify'>You may charge any price or no
price for each copy that you convey, and you may offer support or warranty
protection for a fee.</p>

<p style='text-align:justify'>5. Conveying Modified Source
Versions.</p>

<p style='text-align:justify'>You may convey a work based on
the Program, or the modifications to produce it from the Program, in the form
of source code under the terms of section 4, provided that you also meet all of
these conditions:</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;a) The work must carry prominent notices
stating that you modified it, and giving a relevant date.</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;b) The work must carry prominent notices
stating that it is released under this License and any conditions added under
section 7. This requirement modifies the requirement in section 4 to &ldquo;keep
intact all notices&rdquo;.</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;c) You must license the entire work, as a
whole, under this License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7 additional
terms, to the whole of the work, and all its parts, regardless of how they are
packaged. This License gives no permission to license the work in any other
way, but it does not invalidate such permission if you have separately received
it.</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;d) If the work has interactive user
interfaces, each must display Appropriate Legal Notices; however, if the
Program has interactive interfaces that do not display Appropriate Legal
Notices, your work need not make them do so.</p>

<p style='text-align:justify'>A compilation of a covered work
with other separate and independent works, which are not by their nature
extensions of the covered work, and which are not combined with it such as to
form a larger program, in or on a volume of a storage or distribution medium,
is called an &ldquo;aggregate&rdquo; if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users beyond what
the individual works permit. Inclusion of a covered work in an aggregate does
not cause this License to apply to the other parts of the aggregate.</p>

<p style='text-align:justify'>6. Conveying Non-Source Forms.</p>

<p style='text-align:justify'>You may convey a covered work in
object code form under the terms of sections 4 and 5, provided that you also
convey the machine-readable Corresponding Source under the terms of this
License, in one of these ways:</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;a) Convey the object code in, or embodied
in, a physical product (including a physical distribution medium), accompanied
by the Corresponding Source fixed on a durable physical medium customarily used
for software interchange.</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;b) Convey the object code in, or embodied
in, a physical product (including a physical distribution medium), accompanied
by a written offer, valid for at least three years and valid for as long as you
offer spare parts or customer support for that product model, to give anyone
who possesses the object code either (1) a copy of the Corresponding Source for
all the software in the product that is covered by this License, on a durable
physical medium customarily used for software interchange, for a price no more
than your reasonable cost of physically performing this conveying of source, or
(2) access to copy the Corresponding Source from a network server at no charge.</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;c) Convey individual copies of the object
code with a copy of the written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and only if you
received the object code with such an offer, in accord with subsection 6b.</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;d) Convey the object code by offering
access from a designated place (gratis or for a charge), and offer equivalent
access to the Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the Corresponding
Source along with the object code. If the place to copy the object code is a
network server, the Corresponding Source may be on a different server (operated
by you or a third party) that supports equivalent copying facilities, provided you
maintain clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the Corresponding Source,
you remain obligated to ensure that it is available for as long as needed to
satisfy these requirements.</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;e) Convey the object code using
peer-to-peer transmission, provided you inform other peers where the object
code and Corresponding Source of the work are being offered to the general
public at no charge under subsection 6d.</p>

<p style='text-align:justify'>A separable portion of the object
code, whose source code is excluded from the Corresponding Source as a System
Library, need not be included in conveying the object code work.</p>

<p style='text-align:justify'>A &ldquo;User Product&rdquo; is either (1) a
&ldquo;consumer product&rdquo;, which means any tangible personal property which is
normally used for personal, family, or household purposes, or (2) anything
designed or sold for incorporation into a dwelling. In determining whether a
product is a consumer product, doubtful cases shall be resolved in favor of
coverage. For a particular product received by a particular user, &ldquo;normally
used&rdquo; refers to a typical or common use of that class of product, regardless of
the status of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product is a
consumer product regardless of whether the product has substantial commercial,
industrial or non-consumer uses, unless such uses represent the only
significant mode of use of the product.</p>

<p style='text-align:justify'>&ldquo;Installation Information&rdquo; for a
User Product means any methods, procedures, authorization keys, or other
information required to install and execute modified versions of a covered work
in that User Product from a modified version of its Corresponding Source. The
information must suffice to ensure that the continued functioning of the
modified object code is in no case prevented or interfered with solely because
modification has been made.</p>

<p style='text-align:justify'>If you convey an object code work
under this section in, or with, or specifically for use in, a User Product, and
the conveying occurs as part of a transaction in which the right of possession
and use of the User Product is transferred to the recipient in perpetuity or
for a fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied by the
Installation Information. But this requirement does not apply if neither you
nor any third party retains the ability to install modified object code on the
User Product (for example, the work has been installed in ROM).</p>

<p style='text-align:justify'>The requirement to provide
Installation Information does not include a requirement to continue to provide
support service, warranty, or updates for a work that has been modified or
installed by the recipient, or for the User Product in which it has been
modified or installed. Access to a network may be denied when the modification
itself materially and adversely affects the operation of the network or
violates the rules and protocols for communication across the network.</p>

<p style='text-align:justify'>Corresponding Source conveyed,
and Installation Information provided, in accord with this section must be in a
format that is publicly documented (and with an implementation available to the
public in source code form), and must require no special password or key for
unpacking, reading or copying.</p>

<p style='text-align:justify'>7. Additional Terms.</p>

<p style='text-align:justify'>&ldquo;Additional permissions&rdquo; are
terms that supplement the terms of this License by making exceptions from one
or more of its conditions. Additional permissions that are applicable to the
entire Program shall be treated as though they were included in this License,
to the extent that they are valid under applicable law. If additional
permissions apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by this
License without regard to the additional permissions.</p>

<p style='text-align:justify'>When you convey a copy of a
covered work, you may at your option remove any additional permissions from
that copy, or from any part of it. (Additional permissions may be written to
require their own removal in certain cases when you modify the work.) You may
place additional permissions on material, added by you to a covered work, for
which you have or can give appropriate copyright permission.</p>

<p style='text-align:justify'>Notwithstanding any other provision
of this License, for material you add to a covered work, you may (if authorized
by the copyright holders of that material) supplement the terms of this License
with terms:</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;a) Disclaiming warranty or limiting
liability differently from the terms of sections 15 and 16 of this License; or</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;b) Requiring preservation of specified
reasonable legal notices or author attributions in that material or in the
Appropriate Legal Notices displayed by works containing it; or</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;c) Prohibiting misrepresentation of the
origin of that material, or requiring that modified versions of such material
be marked in reasonable ways as different from the original version; or</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;d) Limiting the use for publicity purposes
of names of licensors or authors of the material; or</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;e) Declining to grant rights under
trademark law for use of some trade names, trademarks, or service marks; or</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;f) Requiring indemnification of licensors
and authors of that material by anyone who conveys the material (or modified
versions of it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on those
licensors and authors.</p>

<p style='text-align:justify'>All other non-permissive
additional terms are considered &ldquo;further restrictions&rdquo; within the meaning of
section 10. If the Program as you received it, or any part of it, contains a
notice stating that it is governed by this License along with a term that is a
further restriction, you may remove that term. If a license document contains a
further restriction but permits relicensing or conveying under this License,
you may add to a covered work material governed by the terms of that license
document, provided that the further restriction does not survive such
relicensing or conveying.</p>

<p style='text-align:justify'>If you add terms to a covered
work in accord with this section, you must place, in the relevant source files,
a statement of the additional terms that apply to those files, or a notice
indicating where to find the applicable terms.</p>

<p style='text-align:justify'>Additional terms, permissive or
non-permissive, may be stated in the form of a separately written license, or
stated as exceptions; the above requirements apply either way.</p>

<p style='text-align:justify'>8. Termination.</p>

<p style='text-align:justify'>You may not propagate or modify a
covered work except as expressly provided under this License. Any attempt
otherwise to propagate or modify it is void, and will automatically terminate
your rights under this License (including any patent licenses granted under the
third paragraph of section 11).</p>

<p style='text-align:justify'>However, if you cease all
violation of this License, then your license from a particular copyright holder
is reinstated (a) provisionally, unless and until the copyright holder
explicitly and finally terminates your license, and (b) permanently, if the
copyright holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.</p>

<p style='text-align:justify'>Moreover, your license from a
particular copyright holder is reinstated permanently if the copyright holder
notifies you of the violation by some reasonable means, this is the first time
you have received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after your
receipt of the notice.</p>

<p style='text-align:justify'>Termination of your rights under
this section does not terminate the licenses of parties who have received
copies or rights from you under this License. If your rights have been
terminated and not permanently reinstated, you do not qualify to receive new
licenses for the same material under section 10.</p>

<p style='text-align:justify'>9. Acceptance Not Required for
Having Copies.</p>

<p style='text-align:justify'>You are not required to accept
this License in order to receive or run a copy of the Program. Ancillary
propagation of a covered work occurring solely as a consequence of using
peer-to-peer transmission to receive a copy likewise does not require
acceptance. However, nothing other than this License grants you permission to
propagate or modify any covered work. These actions infringe copyright if you
do not accept this License. Therefore, by modifying or propagating a covered
work, you indicate your acceptance of this License to do so.</p>

<p style='text-align:justify'>10. Automatic Licensing of
Downstream Recipients.</p>

<p style='text-align:justify'>Each time you convey a covered
work, the recipient automatically receives a license from the original
licensors, to run, modify and propagate that work, subject to this License. You
are not responsible for enforcing compliance by third parties with this
License.</p>

<p style='text-align:justify'>An &ldquo;entity transaction&rdquo; is a
transaction transferring control of an organization, or substantially all
assets of one, or subdividing an organization, or merging organizations. If
propagation of a covered work results from an entity transaction, each party to
that transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could give
under the previous paragraph, plus a right to possession of the Corresponding
Source of the work from the predecessor in interest, if the predecessor has it
or can get it with reasonable efforts.</p>

<p style='text-align:justify'>You may not impose any further
restrictions on the exercise of the rights granted or affirmed under this
License. For example, you may not impose a license fee, royalty, or other
charge for exercise of rights granted under this License, and you may not
initiate litigation (including a cross-claim or counterclaim in a lawsuit)
alleging that any patent claim is infringed by making, using, selling, offering
for sale, or importing the Program or any portion of it.</p>

<p style='text-align:justify'>11. Patents.</p>

<p style='text-align:justify'>A &ldquo;contributor&rdquo; is a copyright
holder who authorizes use under this License of the Program or a work on which
the Program is based. The work thus licensed is called the contributor's
&ldquo;contributor version&rdquo;.</p>

<p style='text-align:justify'>A contributor's &ldquo;essential patent
claims&rdquo; are all patent claims owned or controlled by the contributor, whether
already acquired or hereafter acquired, that would be infringed by some manner,
permitted by this License, of making, using, or selling its contributor
version, but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For purposes of
this definition, &ldquo;control&rdquo; includes the right to grant patent sublicenses in a
manner consistent with the requirements of this License.</p>

<p style='text-align:justify'>Each contributor grants you a
non-exclusive, worldwide, royalty-free patent license under the contributor's
essential patent claims, to make, use, sell, offer for sale, import and
otherwise run, modify and propagate the contents of its contributor version.</p>

<p style='text-align:justify'>In the following three
paragraphs, a &ldquo;patent license&rdquo; is any express agreement or commitment, however
denominated, not to enforce a patent (such as an express permission to practice
a patent or covenant not to sue for patent infringement). To &ldquo;grant&rdquo; such a
patent license to a party means to make such an agreement or commitment not to
enforce a patent against the party.</p>

<p style='text-align:justify'>If you convey a covered work,
knowingly relying on a patent license, and the Corresponding Source of the work
is not available for anyone to copy, free of charge and under the terms of this
License, through a publicly available network server or other readily
accessible means, then you must either (1) cause the Corresponding Source to be
so available, or (2) arrange to deprive yourself of the benefit of the patent
license for this particular work, or (3) arrange, in a manner consistent with
the requirements of this License, to extend the patent license to downstream
recipients. &ldquo;Knowingly relying&rdquo; means you have actual knowledge that, but for
the patent license, your conveying the covered work in a country, or your recipient's
use of the covered work in a country, would infringe one or more identifiable
patents in that country that you have reason to believe are valid.</p>

<p style='text-align:justify'>If, pursuant to or in connection
with a single transaction or arrangement, you convey, or propagate by procuring
conveyance of, a covered work, and grant a patent license to some of the
parties receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license you
grant is automatically extended to all recipients of the covered work and works
based on it.</p>

<p style='text-align:justify'>A patent license is
&ldquo;discriminatory&rdquo; if it does not include within the scope of its coverage,
prohibits the exercise of, or is conditioned on the non-exercise of one or more
of the rights that are specifically granted under this License. You may not
convey a covered work if you are a party to an arrangement with a third party
that is in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying the work,
and under which the third party grants, to any of the parties who would receive
the covered work from you, a discriminatory patent license (a) in connection
with copies of the covered work conveyed by you (or copies made from those
copies), or (b) primarily for and in connection with specific products or
compilations that contain the covered work, unless you entered into that
arrangement, or that patent license was granted, prior to 28 March 2007.</p>

<p style='text-align:justify'>Nothing in this License shall be
construed as excluding or limiting any implied license or other defenses to
infringement that may otherwise be available to you under applicable patent
law.</p>

<p style='text-align:justify'>12. No Surrender of Others'
Freedom.</p>

<p style='text-align:justify'>If conditions are imposed on you
(whether by court order, agreement or otherwise) that contradict the conditions
of this License, they do not excuse you from the conditions of this License. If
you cannot convey a covered work so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as a
consequence you may not convey it at all. For example, if you agree to terms
that obligate you to collect a royalty for further conveying from those to whom
you convey the Program, the only way you could satisfy both those terms and
this License would be to refrain entirely from conveying the Program.</p>

<p style='text-align:justify'>13. Use with the GNU Affero General Public
License.</p>

<p style='text-align:justify'>Notwithstanding any other
provision of this License, you have permission to link or combine any covered
work with a work licensed under version 3 of the GNU Affero
General Public License into a single combined work, and to convey the resulting
work. The terms of this License will continue to apply to the part which is the
covered work, but the special requirements of the GNU Affero
General Public License, section 13, concerning interaction through a network
will apply to the combination as such.</p>

<p style='text-align:justify'>14. Revised Versions of this
License.</p>

<p style='text-align:justify'>The Free Software Foundation may
publish revised and/or new versions of the GNU General Public License from time
to time. Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.</p>

<p style='text-align:justify'>Each version is given a
distinguishing version number. If the Program specifies that a certain numbered
version of the GNU General Public License &ldquo;or any later version&rdquo; applies to it,
you have the option of following the terms and conditions either of that
numbered version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the GNU General
Public License, you may choose any version ever published by the Free Software
Foundation.</p>

<p style='text-align:justify'>If the Program specifies that a
proxy can decide which future versions of the GNU General Public License can be
used, that proxy's public statement of acceptance of a version permanently
authorizes you to choose that version for the Program.</p>

<p style='text-align:justify'>Later license versions may give
you additional or different permissions. However, no additional obligations are
imposed on any author or copyright holder as a result of your choosing to
follow a later version.</p>

<p style='text-align:justify'>15. Disclaimer of Warranty.</p>

<p style='text-align:justify'>THERE IS NO WARRANTY FOR THE
PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE
PROGRAM &ldquo;AS IS&rdquo; WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU
ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>

<p style='text-align:justify'>16. Limitation of Liability.</p>

<p style='text-align:justify'>IN NO EVENT UNLESS REQUIRED BY
APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER
PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO
YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES
SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH
ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.</p>

<p style='text-align:justify'>17. Interpretation of Sections 15
and 16.</p>

<p style='text-align:justify'>If the disclaimer of warranty and
limitation of liability provided above cannot be given local legal effect
according to their terms, reviewing courts shall apply local law that most
closely approximates an absolute waiver of all civil liability in connection
with the Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.</p>

<p style='text-align:justify'>END OF TERMS AND CONDITIONS</p>

<p style='text-align:justify'>How to Apply These Terms to Your
New Programs</p>

<p style='text-align:justify'>If you develop a new program, and
you want it to be of the greatest possible use to the public, the best way to
achieve this is to make it free software which everyone can redistribute and
change under these terms.</p>

<p style='text-align:justify'>To do so, attach the following
notices to the program. It is safest to attach them to the start of each source
file to most effectively state the exclusion of warranty; and each file should
have at least the &ldquo;copyright&rdquo; line and a pointer to where the full notice is found.</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;&lt;one line to give the program's name and
a brief idea of what it does.&gt;</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;Copyright (C) &lt;year&gt; &lt;name of author&gt;</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;This program is free software: you can
redistribute it and/or modify</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;it under the terms of the GNU General
Public License as published by</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;the Free Software Foundation, either
version 3 of the License, or</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;(at your option)
any later version.</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;This program is distributed in the hope
that it will be useful,</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;but WITHOUT ANY WARRANTY; without even the
implied warranty of</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;MERCHANTABILITY or FITNESS FOR A PARTICULAR
PURPOSE. See the</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;GNU General Public License for more
details.</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;You should have received a copy of the GNU
General Public License</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;along with this program. If not, see
&lt;https://www.gnu.org/licenses/&gt;.</p>

<p style='text-align:justify'>Also add information on how to
contact you by electronic and paper mail.</p>

<p style='text-align:justify'>If the program does terminal
interaction, make it output a short notice like this when it starts in an
interactive mode:</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;&lt;program&gt; Copyright (C) &lt;year&gt;
&lt;name of author&gt;</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;This program comes with ABSOLUTELY NO
WARRANTY; for details type `show w'.</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;This is free software, and you are welcome
to redistribute it</p>

<p style='text-align:justify'>&nbsp;&nbsp;&nbsp;&nbsp;under certain conditions; type `show c' for
details.</p>

<p style='text-align:justify'>The hypothetical commands `show
w' and `show c' should show the appropriate parts of the General Public
License. Of course, your program's commands might be different; for a GUI
interface, you would use an &ldquo;about box&rdquo;.</p>

<p style='text-align:justify'>You should also get your employer
(if you work as a programmer) or school, if any, to sign a &ldquo;copyright
disclaimer&rdquo; for the program, if necessary. For more information on this, and
how to apply and follow the GNU GPL, see &lt;https://www.gnu.org/licenses/&gt;.</p>

<p style='text-align:justify'>The GNU General Public License
does not permit incorporating your program into proprietary programs. If your
program is a subroutine library, you may consider it more useful to permit
linking proprietary applications with the library. If this is what you want to
do, use the GNU Lesser General Public License instead of this License. But
first, please read &lt;https://www.gnu.org/licenses/why-not-lgpl.html&gt;.</p>
