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

have obtained a respective licensing right if Customer fails to comply with any
term or condition and such failure is not remedied within thirty (30) days after
notice hereof from Tektronix or such third party. Upon termination by either
party, Customer shall return to Tektronix or destroy, the Program and all
associated documentation, together with all copies in any form.
