This appears to be an original UCB Copyright notice. From
/usr/src/COPYRIGHT:

NOTE: The copyright of UC Berkeley's Berkeley Software Distribution
("BSD") source has been updated.  The copyright addendum may be found at
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change and is
included below.

July 22, 1999

To All Licensees, Distributors of Any Version of BSD:

As you know, certain of the Berkeley Software Distribution ("BSD")
source code files require that further distributions of products
containing all or portions of the software, acknowledge within their
advertising materials that such products contain software developed by
UC Berkeley and its contributors.

Specifically, the provision reads:

"     * 3. All advertising materials mentioning features or use of this
software      *    must display the following acknowledgement:
      *    This product includes software developed by the University of
      *    California, Berkeley and its contributors."

Effective immediately, licensees and distributors are no longer required
to include the acknowledgement within advertising materials. 
Accordingly, the foregoing paragraph of those BSD Unix files containing
it is hereby deleted in its entirety.

Director, Office of Technology Licensing
University of California, Berkeley
