royalty-free, non-exclusive license, to the extent of Apples Applicable
Patent Rights and copyrights covering the Original Code, to do the
following:
2.1 Unmodified Code. You may use, reproduce, display, perform, internally
distribute within Your organization, and Externally Deploy verbatim,
unmodified copies of the Original Code, for commercial or non-
commercial purposes, provided that in each instance:
(a) You must retain and reproduce in all copies of Original Code the
copyright and other proprietary notices and disclaimers of Apple as
they appear in the Original Code, and keep intact all notices in the
Original Code that refer to this License; and
(b) You must include a copy of this License with every copy of Source
Code of Covered Code and documentation You distribute or
Externally Deploy, and You may not offer or impose any terms on
such Source Code that alter or restrict this License or the recipients’
rights hereunder, except as permitted under Section 6.
2.2 Modified Code. You may modify Covered Code and use, reproduce,
display, perform, internally distribute within Your organization, and
Externally Deploy Your Modifications and Covered Code, for commercial
or non-commercial purposes, provided that in each instance You also
meet all of these conditions:

Source Code of the Covered Code;
(b) You must duplicate, to the extent it does not already exist, the notice

and cause the modified files to carry prominent notices stating that
You changed the files and the date of any change; and
(c) If You Externally Deploy Your Modifications, You must make Source

those to whom You have Externally Deployed Your Modifications, or
publicly available. Source Code of Your Externally Deployed
Modifications must be released under the terms set forth in this
License, including the license grants set forth in Section 3 below, for
as long as you Externally Deploy the Covered Code or twelve (12)
months from the date of initial External Deployment, whichever is
longer. You should preferably distribute the Source Code of Your
Externally Deployed Modifications electronically (e.g. download from
a web site).
2.3 Distribution of Executable Versions. In addition, if You Externally Deploy
Covered Code (Original Code and/or Modifications) in object code,
executable form only, You must include a prominent notice, in the code
itself as well as in related documentation, stating that Source Code of the
Covered Code is available under the terms of this License with
information on how and where to obtain such Source Code.
2.4 Third Party Rights. You expressly acknowledge and agree that although
Apple and each Contributor grants the licenses to their respective
portions of the Covered Code set forth herein, no assurances are
provided by Apple or any Contributor that the Covered Code does not
infringe the patent or other intellectual property rights of any other entity.
Apple and each Contributor disclaim any liability to You for claims
brought by any other entity based on infringement of intellectual property
rights or otherwise. As a condition to exercising the rights and licenses
granted hereunder, You hereby assume sole responsibility to secure any
other intellectual property rights needed, if any. For example, if a third
party patent license is required to allow You to distribute the Covered
Code, it is Your responsibility to acquire that license before distributing
the Covered Code.
3. Your Grants. In consideration of, and as a condition to, the licenses
granted to You under this License, You hereby grant to any person or
entity receiving or distributing Covered Code under this License a non-
exclusive, royalty-free, perpetual, irrevocable license, under Your
Applicable Patent Rights and other intellectual property rights (other than
patent) owned or controlled by You, to use, reproduce, display, perform,
modify, sublicense, distribute and Externally Deploy Your Modifications of
the same scope and extent as Apple's licenses under Sections 2.1 and
2.2 above.
4. 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 each such instance,
You must make sure the requirements of this License are fulfilled for the
Covered Code or any portion thereof.
5. Limitations on Patent License. Except as expressly stated in Section 2,
no other patent rights, express or implied, are granted by Apple herein.
Modifications and/or Larger Works may require additional patent
licenses from Apple which Apple may grant in its sole discretion.
6. Additional Terms. You may choose to offer, and to charge a fee for,
warranty, support, indemnity or liability obligations and/or other rights
consistent with the scope of the license granted herein (“Additional
Terms”) to one or more recipients of Covered Code. However, You may
do so only on Your own behalf and as Your sole responsibility, and not on
behalf of Apple or any Contributor. You must obtain the recipient's
agreement that any such Additional Terms are offered by You alone, and
You hereby agree to indemnify, defend and hold Apple and every
Contributor harmless for any liability incurred by or claims asserted
against Apple or such Contributor by reason of any such Additional
Terms.
