          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
            Section 1.1, Licensee must make its Necessary Claims available 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,

          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

          ANY OTHER PARTY FOR LOST PROFITS OR ANY FORM OF INDIRECT, SPECIAL,
          INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER FROM ANY CAUSES OF
          ACTION OF ANY KIND WITH RESPECT TO THIS LICENSE, WHETHER BASED ON BREACH
