1. License Terms.

1.1. Patent License. Subject to the terms and conditions of this License, each
     Licensor, on behalf of itself and successors in interest and assigns,
     grants Licensee a non-sublicensable, perpetual, worldwide, non-exclusive,
     no-charge, royalty-free, irrevocable (except as expressly stated in this
     License) patent license to its Necessary Claims to make, use, sell, offer
     for sale, import or distribute any Implementation.

1.2. Conditions.

1.2.1. Availability. As a condition to the grant of rights to Licensee to make,
       sell, offer for sale, import or distribute an Implementation under

       this License, and must reproduce this License with any Implementation
       as follows:

       a. For distribution in source code, by including this License in the
          root directory of the source code with its Implementation.

       b. For distribution in any other form (including binary, object form,
          and/or hardware description code (e.g., HDL, RTL, Gate Level Netlist,

1.3. Defensive Termination. If any Licensee, its Affiliates, or its agents
     initiates patent litigation or files, maintains, or voluntarily
     participates in a lawsuit against another entity or any person asserting
     that any Implementation infringes Necessary Claims, any patent licenses
     granted under this License directly to the Licensee are immediately
     terminated as of the date of the initiation of action unless 1) that suit
     was in response to a corresponding suit regarding an Implementation first
     brought against an initiating entity, or 2) that suit was brought to
     enforce the terms of this License (including intervention in a third-party
     action by a Licensee).
