  Recipient has requested a license and Intel Corporation ("Intel") is willing
  to grant a license for the software entitled Linux Base Driver for the
  Intel(R) PRO/1000 Family of Adapters (e1000) (the "Software") being provided
  by Intel Corporation. The following definitions apply to this license:
  
  "Licensed Patents" means patent claims licensable by Intel Corporation which
  are necessarily infringed by the use of sale of the Software alone or when
  combined with the operating system referred to below.
  
  "Recipient" means the party to whom Intel delivers this Software.
  
  "Licensee" means Recipient and those third parties that receive a license to
  any operating system available under the GNU General Public License 2.0 or
  later.

  to sell, import and otherwise transfer the Software, if any, in source code
  and object code form. This license shall include changes to the Software
  that are error corrections or other minor changes to the Software that do
  not add functionality or features when the Software is incorporated in any
  version of an operating system that has been distributed under the GNU
  General Public License 2.0 or later. This patent license shall apply to the
  combination of the Software and any operating system licensed under the GNU
  General Public License 2.0 or later if, at the time Intel provides the
  Software to Recipient, such addition of the Software to the then publicly
  available versions of such operating systems available under the GNU General
  Public License 2.0 or later (whether in gold, beta or alpha form) causes
  such combination to be covered by the Licensed Patents. The patent license
  shall not apply to any other combinations which include the Software. NO
