grants You a world-wide, royalty-free, non-exclusive license, subject to third
party intellectual property claims, to use, reproduce, modify, display, perform,
sublicense and distribute the Original Code (or portions thereof) with or without
Modifications, and/or as part of a Larger Work.

2.2. Contributor Grant. Subject to third party intellectual property claims
and to the terms and conditions of this Agreement, each Contributor hereby grants
You a world-wide, royalty-free, non-exclusive license to use, reproduce, modify,
display, perform, sublicense and distribute the Modifications created by such
Contributor (or portions thereof) either on an unmodified basis, with other
Modifications, as Covered Code and/or as part of a Larger Work.

2.3. Larger Works. You may create a Larger Work by combining Covered Code with
other code not governed by the terms of this License and distribute the Larger
Work as a single product. In such a case, You must make sure the requirements
of this License are fulfilled for the Covered Code.

Section 3. Distribution Obligations.

3.1. Application of License. The Modifications which You create or to which
You contribute shall be governed by the terms of this License, including without
limitation Section 2.2. The Source Code version of Covered Code may be distributed
only under the terms of this License or a future version of this License released
under Section 6.1, and You must include a copy of this License with every copy
of the Source Code You distribute. You may not offer or impose any terms on
any Source Code version that alters or restricts the applicable version of this
License or the recipients' rights hereunder.

3.2. Availability of Source Code. Any Modification which You create or to which
You contribute must be made available in Source Code form under the terms of
this License either on the same media as an Executable version or via a generally
accepted mechanism for the electronic transfer of data (hereinafter "Electronic
Distribution Mechanism"), to anyone to whom you made an Executable version available;
and if made available via Electronic Distribution Mechanism, such source code
must remain available for at least twelve (12) months after the date it initially
became available, or at least six (6) months after a subsequent version of that
particular Modification has been made available to such recipients. You are
responsible for ensuring that the Source Code version remains available even
if the Electronic Distribution Mechanism is maintained by a third party.

3.3. Description of Modifications. You must cause all Covered Code to which
You contribute to contain a file documenting the changes You made to create
that Covered Code and the date of any change. You must include a prominent statement
that the Modification is derived, directly or indirectly, from Original Code
provided by LEGO and including the name of LEGO® in (a) the Source Code, and
(b) in any notice in an Executable version or related documentation in which
You describe the origin or ownership of the Covered Code.

3.4. Intellectual Property Matters. (a) Third Party Claims. If Contributor has
knowledge that a license under a third party's intellectual property rights
is required to exercise the rights granted by such Contributor under Sections
2.1 or 2.2, Contributor must include a text file with the Source Code distribution
titled "LEGAL which describes the claim and the party making the claim in sufficient
detail that a recipient will know whom to contact. If Contributor obtains such
knowledge after the Modification is made available as described in Section 3.2,
Contributor shall promptly modify the LEGAL file in all copies Contributor makes
available thereafter and shall take other steps (such as notifying appropriate
mailing lists or newsgroups) reasonably calculated to inform those who received
the Covered Code that new knowledge has been obtained. (b) Contributor APIs.
If Contributor's Modifications include an application programming interface
and Contributor has knowledge of patent licenses which are reasonably necessary
to implement that API, Contributor must also include this information in the
LEGAL file. (c) Representations. Contributor represents that, except as disclosed
pursuant to Section 3.4(a) above, Contributor believes that Contributor's Modifications
are Contributor's original creation(s) and/or Contributor has sufficient rights
to grant the rights conveyed by this License.

3.5. Required Notices. You must duplicate the notice in Exhibit A in each file
of the Source Code. If it is not possible to put such notice in a particular
Source Code file due to its structure, then You must include such notice in
a location (such as a relevant directory) where a user would be likely to look
for such a notice. If You created one or more Modification(s) You may add your
name as a Contributor to the notice described in Exhibit A. You must also duplicate
this License in any documentation for the Source Code where You describe recipients'
rights or ownership rights relating to Covered Code.

3.6. Distribution of Executable Versions. You may distribute Covered Code in
Executable form only if the requirements of Section 3.1-3.5 have been met for
that Covered Code, and if You include a notice stating that the Source Code
version of the Covered Code is available under the terms of this License, including
a description of how and where You have fulfilled the obligations of Section
3.2. The notice must be conspicuously included in any notice in an Executable
version, related documentation or collateral in which You describe recipients'
rights relating to the Covered Code. You must distribute the Executable version
of Covered Code under the terms of this License.

Section 4. Inability to Comply Due to Statute or Regulation.

If it is impossible for You to comply with any of the terms of this License
with respect to some or all of the Covered Code due to statute, judicial order,
or regulation then You must: (a) comply with the terms of this License to the
maximum extent possible; and (b) describe the limitations and the code they
affect. Such description must be included in the LEGAL file described in Section
3.4 and must be included with all distributions of the Source Code. Except to
the extent prohibited by statute or regulation, such description must be sufficiently
detailed for a recipient of ordinary skill to be able to understand it.

Section 5. Exclusions. Notwithstanding anything to the contrary herein, no Software
(as defined in the Mindstorms® NXT EULA) shall be released or made available
as open source under this License, regardless of how any Covered Code interacts
with any Software (as defined in the Mindstorms® NXT EULA).

Section 6. Versions of the License.

6.1. New Versions. LEGO may publish revised and/or new versions of the License
from time to time. Each version will be given a distinguishing version number.

6.2. Effect of New Versions. Once Covered Code has been published under a particular
version of the License, You may always continue to use it under the terms of
that version. You may also choose to use such Covered Code under the terms of
any subsequent version of the License published by LEGO. No one other than LEGO
has the right to modify the terms applicable to Covered Code created under this
License.

Section 7. Disclaimer of Warranty.

ALL COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS BASIS, WITHOUT
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION,
WARRANTIES THAT THE COVERED CODE IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A
PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE COVERED CODE IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE
IN ANY RESPECT, YOU (NOT LEGO OR ITS SUPPLIERS OR LICENSORS OR ANY OTHER CONTRIBUTOR)
ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER
OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED
CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.

THE COVERED CODE HAS BEEN DESIGNED TO BE USED IN THE TOY INDUSTRY ONLY. THEREFORE
ITS FUNCTIONALITY IS LIMITED AND CAN BE IMPACTED BY NUMEROUS FACTORS SUCH AS
POWER FLUCTUATIONS, HARDWARE MALFUNCTIONS, AND MANY OTHER ITEMS. YOU ACKNOWLEDGE
AND AGREE THAT THE COVERED CODE SHOULD NOT BE USED IN ANY APPLICATION WHERE
ITS FAILURE TO PROPERLY FUNCTION WOULD CREATE A RISK OF HARM TO PROPERTY OR
PERSONS.

Section 8. Termination.

8.1. This License and the rights granted hereunder will terminate automatically
if You fail to comply with terms herein and fail to cure such breach within
30 days of becoming aware of the breach. All sublicenses to the Covered Code
which are properly granted shall survive any termination of this License. Provisions
which, by their nature, must remain in effect beyond the termination of this
License shall survive. 8.2. If You initiate litigation by asserting a patent
infringement claim (excluding declatory judgment actions) against LEGO or a
Contributor (LEGO or Contributor against whom You file such action is referred
to as "Participant") alleging that such Participant's Contributor Version directly
or indirectly infringes any patent, then any and all rights granted by such
Participant to You under Sections 2.1 and/or 2.2 of this License shall, upon
60 days notice from Participant terminate prospectively, unless if within 60
days after receipt of notice You either: (i) agree in writing to pay Participant
a mutually agreeable reasonable royalty for Your past and future use of Modifications
made by such Participant, or (ii) withdraw Your litigation claim with respect
to the Contributor Version against such Participant. If within 60 days of notice,
a reasonable royalty and payment arrangement are not mutually agreed upon in
writing by the parties or the litigation claim is not withdrawn, the rights
granted by Participant to You under Sections 2.1 and/or 2.2 automatically terminate
at the expiration of the 60 day notice period specified above. 8.3. If You assert
a patent infringement claim against Participant alleging that such Participant's
Contributor Version directly or indirectly infringes any patent where such claim
is resolved (such as by license or settlement) prior to the initiation of patent
infringement litigation, then the reasonable value of the licenses granted by
such Participant under Sections 2.1 or 2.2 shall be taken into account in determining
the amount or value of any payment or license. 8.4. In the event of termination
under Sections 8.1 or 8.2 above, all end user license agreements (excluding
distributors and resellers) which have been validly granted by You or any distributor
hereunder prior to termination shall survive termination.

Section 9. Limitation of Liability.

UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING NEGLIGENCE),
CONTRACT, OR OTHERWISE, SHALL YOU, LEGO, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR
OF COVERED CODE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON
FOR ANY DIRECT, INDIRECT, SPECIAL, PUNITIVE, INCIDENTAL, OR CONSEQUENTIAL DAMAGES
OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF BUSINESS
PROFITS, BUSINESS INTERRUPTION, LOSS OF BUSINESS INFORMATION, DAMAGES FOR LOSS
OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL
OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED
OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT APPLY
TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING FROM SUCH PARTY'S NEGLIGENCE
TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO
NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES,
SO THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.

only those rights set forth herein.

Section 11. Responsibility for Claims.

As between LEGO and the Contributors, each party is responsible for claims and
damages arising, directly or indirectly, out of its utilization of rights under
this License and You agree to work with LEGO and Contributors to distribute
such responsibility on an equitable basis. Nothing herein is intended or shall
be deemed to constitute any admission of liability.
