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/100 Family of Adapters (e100) (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 
hardware per se is licensed hereunder.
