This Contributor License Agreement from and between Merlinux GmbH, with office at Reichgrafen Str. 20, 79102 Freiburg, and the contributor is a modified version of the Open Whisper Systems Contributor License agreement.

In order to clarify the intellectual property license granted with Contributions from any person to us (Merlinux GmbH), we must have a Contributor License Agreement 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 Merlinux; it does not change your rights to use your own Contributions for any other purpose.

# Contributor License Agreement

1. Definitions.
   “You” (or “Your”) shall mean the copyright owner or legal entity authorized 
   by the copyright owner that is making this Agreement with Merlinux GmbH.
   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 any original work of authorship or invention,
   including any modifications or additions to an existing work, 
   that is intentionally submitted by You to Merlinux for inclusion in,
   or documentation of, any of the products owned or managed by 
   Merlinux (the “Work”). For the purposes of this definition,
   “Submitted” means any form of electronic, verbal, or written communication
   sent to Merlinux 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, Merlinux 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.”

   of your future or actual submissions.

   royalty-free, irrevocable copyright license to reproduce, prepare derivative
   works of, publicly display, publicly perform, and distribute Your

   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) was 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.
5. Entitled to Grant License. You represent that you are legally entitled to
   grant the above license. If your employer(s) has rights to intellectual
   property that you create that includes your Contributions, you represent
   that you have received permission to make Contributions on behalf of that
   employer, that your employer has waived such rights for your contributions
   to Merlinux, or that your employer has executed with Merlinux a separate
   contributor license agreement substantially similar to this Agreement.

   original creation (see section 7 for submissions on behalf of others).

   except to the extent You desire to provide support.

   original creation, You may submit it to Merlinux 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 “Not a Contribution”. Third-party materials

   text with the appropriate license name(s)).
