guardian, or Legal Entity.
Third Party Programs (as defined below), even if included with the distribution
of the Materials, are governed by separate third party license terms, including
without limitation, open source software license terms. Such third party license
terms (and not this Agreement) govern Your use of the Third Party Programs, and
Intel is not liable for the Third Party Programs.
1. LICENSE DEFINITIONS:
"Licensed Patent Claims" means the claims of Intel's patents that are
necessarily and directly infringed by the reproduction and distribution of the
Materials that is authorized in Section 2 below, when the Materials are in its
unmodified form as delivered by Intel to You and not modified or combined with
anything else. Licensed Patent Claims are only those claims that Intel can
license without paying, or getting the consent of, a third party.
"Materials" means Sample Source Code, Redistributables, and End-User
Documentation but do not include Third Party Programs.
"Sample Source Code" means Source Code files that are identified as sample code
and which may include example interface or application source code, and any
updates, provided under this Agreement.
"Source Code" is defined as the software (and not documentation or text) portion
of the Materials provided in human readable format, and includes modifications
that You make or are made on Your behalf as expressly permitted under the terms
of this Agreement.
"Redistributables" means header, library, and dynamically linkable library
files, and any updates, provided under this Agreement.
"Third Party Programs" (if any) are the third party software files that may be
included with the Materials for the applicable software that include a separate
third party license agreement in an attached text file.
"End-User Documentation" means textual materials intended for end users relating
to the Materials.
2. LICENSE GRANT:
Subject to the terms and conditions of this Agreement, Intel grants You a
non-exclusive, worldwide, non-assignable, royalty-free limited right and
license:
A. under its copyrights, to:
1) Copy, modify, and compile the Sample Source Code and distribute it solely
in Your products in executable and source code form;
2) Copy and distribute the Redistributables solely with Your products;
3) Copy, modify, and distribute the End User Documentation solely with Your
products.
B. Under its patents, to:
1) make copies of the Materials internally only;
2) use the Materials internally only; and 3) offer to distribute, and
distribute, but not sell, the Materials only as part of or with Your
products, under Intel's copyright license granted in Section 2(A) but only
under the terms of that copyright license and not as a sale (but this
right does not include the right to sub-license);
4) provided, further, that the license under the Licensed Patent Claims does
not and will not apply to any modifications to, or derivative works of,
the Materials, whether made by You, Your end user (which, for all purposes
under this Agreement, will mean either an end user, a customer, reseller,
distributor or other channel partner), or any third party even if the
modification and creation of derivative works are permitted under 2(A).
3. LICENSE RESTRICTIONS:
Except as expressly provided in this Agreement, You may not:
i. use, copy, distribute or publicly display the Materials;
ii. reverse-assemble, reverse-compile, or otherwise reverse-engineer any
software provided solely in binary form,
iii. rent or lease the Materials to any third party;
iv. assign this Agreement or display the Materials;
v. assign this Agreement or transfer the Materials;
vi. modify, adapt or translate the Materials in whole or in part;
vii. distribute, sublicense or transfer the source code form of the Materials
or derivatives thereof to any third party;
viii. distribute the Materials except as part of Your products;

against any claims or lawsuits, including attorney's fees, that arise or
result from your distribution of any product.
4. OWNERSHIP:
Title to the Materials and all copies thereof remain with Intel or its
suppliers. The Materials are copyrighted and are protected by United States
copyright laws and international treaty provisions. You will not remove any
copyright notice from the Materials. You agree to prevent unauthorized copying
of the Materials. Except as expressly provided herein, Intel does not grant any
express or implied right to you under Intel patents, copyrights, trademarks, or
trade secret information.
5. NO WARRANTY AND NO SUPPORT:
Disclaimer. Intel disclaims all warranties of any kind and the terms and
remedies provided in this Agreement are instead of any other warranty or
condition, express, implied or statutory, including those regarding
merchantability, fitness for any particular purpose, non-infringement or any
warranty arising out of any course of dealing, usage of trade, proposal,
specification or sample. Intel does not assume (and does not authorize any
person to assume on its behalf) any other liability.
Intel may make changes to the Materials, or to items referenced therein, at any
time without notice, but is not obligated to support, update or provide training
for the Materials. Intel may in its sole discretion offer such support, update
or training services under separate terms at Intel's then-current rates. You
may request additional information on Intel's service offerings from an Intel
sales representative.
6. USER SUBMISSIONS:
You agree that any material, information, or other communication, including all
data, images, sounds, text, and other things embodied therein, you transmit or
post to an Intel website will be considered non-confidential ("Communications").

Communications. You agree that Intel and its designees will be free to copy,
modify, create derivative works, publicly display, disclose, distribute, license
and sublicense through multiple tiers of distribution and licensees,
incorporate, and otherwise use the Communications, including derivative works
thereto, for any and all commercial or non-commercial purposes.
7.LIMITATION OF LIABILITY:
Neither Intel nor its suppliers shall be liable for any damages whatsoever
(including, without limitation, damages for loss of business profits, business
interruption, loss of business information, or other loss) arising out of the
use of or inability to use the Materials, even if Intel has been advised of the
possibility of such damages. Because some jurisdictions prohibit the exclusion
or limitation of liability for consequential or incidental damages, the above
limitation may not apply to You.
8. TERM AND TERMINATION:
This Agreement commences upon Your copying, installing or using the Materials
and continues until terminated. Either You or Intel may terminate this
Agreement at any time upon 30 days prior written notice to the other party.
Intel may terminate this license at any time if you are in breach of any of its
terms and conditions. Upon termination, You will immediately destroy the
Materials or return all copies of the Materials to Intel along with any copies
You have made. After termination, the license grant to any Materials or
Redistributables distributed by You in accordance with the terms and conditions
of this Agreement, prior to the effective date of such termination, will survive
any such termination of this Agreement.
