      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

      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).

      (express, implied, or otherwise), including implied warranties of
      merchantability, non-infringement, fitness for a particular purpose, or
      title, related to the material. IN NO EVENT WILL LICENSOR BE LIABLE TO
      ANY OTHER PARTY FOR LOST PROFITS OR ANY FORM OF INDIRECT, SPECIAL,
      INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER FROM ANY CAUSES OF
