Hugin Ad-hoc-Meldung nach § 15 WpHG: Kapitalbeteiligung: ADVA AG Optical Networking: JDS UNIPHASE SELLS REMAINING 11.6% STAKE IN ADVA OPTICAL NETWORKING

Martinsried/Munich, Germany; Mahwah, New Jersey, USA. February 14,
2006. JDS Uniphase today sold all 4,269,616 shares in ADVA it had
owned before, or about 11.6% of ADVA's issued shares. The transaction
followed an earlier sale of about 4.3 million shares in ADVA executed
in September 2005 and is part of an overall optimization of JDS
Uniphase's general investment portfolio. The shares were offered in a
private placement to institutional investors by JPMorgan by way of an
accelerated bookbuilding process earlier today. The offering was
successfully placed with an international group of high quality
institutional investors. The price per share amounted to EUR 7.25 per
share. The disposition of JDS Uniphase's remaining stake in ADVA
increases the free float from 68% to about 80%.
