**Software Grant and Corporate Contributor License Agreement ("Agreement") v2.1**

Thank you for your interest in the project specified above (the “Project”). In
order to clarify the intellectual property license granted with Contributions
from any person or entity, the Project must have a Contributor License Agreement
(CLA) on file that has been signed by each Contributor, indicating agreement to
the license terms below. This license is for your protection as a Contributor as
well as the protection of the Project and its users; it does not change your
rights to use your own Contributions for any other purpose.

This version of the Agreement allows an entity (the “Corporation”) to submit
Contributions to the Project, to authorize Contributions submitted by its
designated employees to the Project, and to grant copyright and patent licenses
thereto.

If you have not already done so, please complete and sign this Agreement using
the electronic signature portal made available to you by the Project or its
third-party service providers, or email a PDF of the signed agreement to the
email address specified above. Please read this document carefully before
signing and keep a copy for your records.

You accept and agree to the following terms and conditions for Your present and
future Contributions submitted to the Project. In return, the Project shall not
use Your Contributions in a way that is contrary to the public benefit or
inconsistent with its charter at the time of the Contribution. Except for the
license granted herein to the Project and recipients of software distributed by
the Project, You reserve all right, title, and interest in and to Your
Contributions.

1. Definitions.

   “You” (or “Your”) shall mean the copyright owner or legal entity authorized by
   the copyright owner that is making this Agreement with the Project. For legal
   entities, the entity making a Contribution and all other entities that
   control, are controlled by, or are under common control with that entity are
   considered to be a single Contributor. For the purposes of this definition,
   “control” means (i) the power, direct or indirect, to cause the direction or
   management of such entity, whether by contract or otherwise, or (ii) ownership
   of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial
   ownership of such entity.

   “Contribution” shall mean the code, documentation or other original works of
   authorship, including any modifications or additions to an existing work, that
   is intentionally submitted by You to the Project for inclusion in, or
   documentation of, any of the products owned or managed by the Project (the
   “Work”). For the purposes of this definition, “submitted” means any form
   of electronic, verbal, or written communication sent to the Project or its
   representatives, including but not limited to communication on electronic
   mailing lists, source code control systems, and issue tracking systems that
   are managed by, or on behalf of, the Project for the purpose of discussing and
   improving the Work, but excluding communication that is conspicuously marked
   or otherwise designated in writing by You as “Not a Contribution.”

2. Grant of Copyright License. Subject to the terms and conditions of this
   Agreement, You hereby grant to the Project and to recipients of software
   distributed by the Project a perpetual, worldwide, non-exclusive, no-charge,
   royalty-free, irrevocable copyright license to reproduce, prepare
   derivative works of, publicly display, publicly perform, sublicense,
   and distribute Your Contributions and such derivative works.

3. Grant of Patent License. Subject to the terms and conditions of this
   Agreement, You hereby grant to the Project and to recipients of software
   distributed by the Project a perpetual, worldwide, non-exclusive, no-charge,
   royalty-free, irrevocable (except as stated in this section) patent
   license to make, have made, use, offer to sell, sell, import, and
   otherwise transfer the Work, where such license applies only to
   those patent claims licensable by You that are necessarily infringed
   by Your Contribution(s) alone or by combination of Your
   Contribution(s) with the Work to which such Contribution(s) were
   submitted. If any entity institutes patent litigation against You or
   any other entity (including a cross-claim or counterclaim in a
   lawsuit) alleging that your Contribution, or the Work to which
   you have contributed, constitutes direct or contributory patent
   infringement, then any patent licenses granted to that entity under
   this Agreement for that Contribution or Work shall terminate as of
   the date such litigation is filed.

4. You represent that You are legally entitled to grant the above license. You
   represent further that the employee of the Corporation designated as the Initial
   CLA Manager below (and each who is designated in a subsequent written
   modification to the list of CLA Managers) (each, a “CLA Manager”) is
   authorized to maintain with the Project (1) the list of employees of the
   Corporation who are authorized to submit Contributions on behalf of the
   Corporation, and (2) the list of CLA Managers.

5. You represent that each of Your Contributions is Your original creation (see
   section 7 for submissions on behalf of others).

6. You are not expected to provide support for Your Contributions, except to the
   extent You desire to provide support. You may provide support for free, for a
   fee, or not at all. Unless required by applicable law or agreed to in writing,
   You provide Your Contributions on an “AS IS” BASIS, WITHOUT WARRANTIES OR
   CONDITIONS OF ANY KIND, either express or implied, including, without
   limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT,
   MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.

7. Should You wish to submit work that is not Your original creation, You may
   submit it to the Project separately from any Contribution, identifying the
   complete details of its source and of any license or other restriction
   (including, but not limited to, related patents, trademarks, and license
   agreements) of which you are personally aware, and conspicuously marking the
   work as “Submitted on behalf of a third-party: [named here]”.

8. It is your responsibility to notify the Project when any change is required
   to the list of designated employees authorized to submit Contributions on behalf
   of the Corporation, or to the list of the CLA Managers.
