LEGO® OPEN SOURCE LICENSE AGREEMENT 1.0
                LEGO® MINDSTORMS® NXT FIRMWARE

This LEGO® Open Source License Agreement is an open source license for
the firmware of the LEGO® MINDSTORMS® NXT microprocessor.

IMPORTANT -- READ CAREFULLY: THIS AGREEMENT ONLY COVERS THE FIRMWARE OF
THE LEGO® MINDSTORMS® NXT MICROPROCESSOR AND DOES NOT COVER ANY
"SOFTWARE" AS DEFINED IN THE MINDSTORMS® NXT END USER LICENSE AGREEMENT
(HEREINAFTER THE "MINDSTORMS® NXT EULA").

Section 1. Definitions.

"Contributor" means each entity that creates or contributes to the
creation of Modifications.

"Contributor Version" means the combination of the Original Code, prior
Modifications used by a Contributor, and the Modifications made by that
particular Contributor.

"Covered Code" means the Original Code or Modifications or the
combination of the Original Code and Modifications, in each case
including portions thereof.

"Executable" means Covered Code in any form other than Source Code.

"Larger Work" means a work which combines Covered Code or portions
thereof with code not governed by the terms of this License.

"License" means this document.

"Modifications" means any addition to or deletion from the substance or
structure of either the Original Code or any previous Modifications.
When Covered Code is released as a series of files, a Modification is
(a) any addition to or deletion from the contents of a file containing
Original Code or previous Modifications, or (b) any new file that
contains any part of the Original Code or previous Modifications.

"Original Code" means Source Code for the firmware of the LEGO®
MINDSTORMS® NXT microprocessor, and which, at the time of its release
under this License is not already Covered Code governed by this
License.

"Source Code" means the preferred form of the Covered Code for making
modifications to it, including all modules it contains, plus any
associated interface definition files, scripts used to control
compilation and installation of an Executable, or source code
differential comparisons against either the Original Code or another
well known, available Covered Code of the Contributor's choice. The
Source Code can be in a compressed or archival form, provided the
appropriate decompression or de-archiving software is widely available
for no charge.

"You" (or "Your") means an individual or a legal entity exercising
rights under, and complying with all of the terms of, this License or a
future version of this License issued under Section 6.1. For legal
entities, "You'' includes any entity which controls, is controlled by,
or is under common control with You. For purposes of this definition,
"control'' means (a) the power, direct or indirect, to cause the
direction or management of such entity, whether by contract or
otherwise, or (b) ownership of more than fifty percent (50%) of the
outstanding shares or beneficial ownership of such entity.

Section 2. Source Code License and Larger Works.

2.1.  LEGO Grant.  LEGO 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, 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,
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 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.

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 INDIRECT,
SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER
INCLUDING, WITHOUT LIMITATION, 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.

Section 10.  U.S. Government End Users.

The Covered Code is a "commercial item," as that term is defined in
48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
software" and "commercial computer software documentation," as such
terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48
C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995),
all U.S. Government End Users acquire Covered Code with 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.

Section 12.   Trademarks.

This License does not grant, nor shall any provision of this License be
construed as granting, any rights or permission to use the trade names,
trademarks, service marks, or product names of LEGO.

Section 13.  Governing Law

To the extent possible under applicable law, this License shall be
governed by Danish law and shall be subject to the non-exclusive
jurisdiction of the Commercial and Maritime Court of Copenhagen. This
License will not be governed by the United Nations Convention of
Contracts for the International Sale of Goods, the application of which
is hereby expressly excluded. You acknowledge that the export of any
Covered Code is governed by the export control laws of the United
States of America and other countries. If you are downloading any
Covered Code, You represent and warrant that You are not located in or
under the control of any country which the export laws and regulations
of such country or of the United States prohibit the exportation of the
Covered Code.

Section 14.  Miscellaneous.

This License represents the complete agreement concerning subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent
necessary to make it enforceable. Any law or regulation which provides
that the language of a contract shall be construed against the drafter
shall not apply to this License.
