THESE TERMS AND CONDITIONS. UPON TRANSFER OF ANY COPY,
MODIFICATION, OR MERGED PORTION OF THE PROGRAM, THE
LICENSE GRANTED HEREIN IS AUTOMATICALLY TERMINATED WITH
RESPECT TO THE PARTY THAT TRANSFERS THE PROGRAM.

The license granted herein is effective upon acceptance by Customer, and shall
remain in effect until terminated as provided herein. The license may be
terminated by Customer at any time upon written notice to Tektronix. The license
