follows the successful collaboration between the two companies in developing
the UltreX</font><font face="Symbol" style="font-family:Symbol;">&#212;</font> and DefiniTV<font face="Symbol" style="font-family:Symbol;">&#212;</font> light engines for the fast growing,
large-screen segment of this market.</p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&#147;High
definition requires high performance optics and this acquisition is an
important step toward delivering the advanced technology needed for the large
screen display market,&#148; said Hoss Christensen, head of JDS Uniphase&#146;s Laser,
Optics and Display Products Group. &#147;Our light engines have already gained
industry recognition for technical excellence. We believe customers choosing
either UltreX or DefiniTV solutions will enjoy one of the highest quality images
available.&#148;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">JDS
Uniphase&#146;s UltreX light engine is designed for use with
liquid-crystal-on-silicon (LCOS) microdisplay technology used by Brillian
Corporation and others. The DefiniTV light engine is designed for Digital Light
Processing (DLP</font><font face="Symbol" style="font-family:Symbol;">&#212;</font>) imagers, a microdisplay technology
developed by Texas Instruments. UltreX and DefiniTV, which have both gained
industry acceptance and recognition for their performance in rear projection
televisions (RPTV), are now in production.</p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
overall market size for large screen televisions using microdisplay technology
exceeds $4 billion and is expected to be a fast growing segment of the market,
while cathode ray tubes, currently the dominant technology, are expected to
decline, according to leading display industry research firm iSuppli
Corporation. JDS Uniphase light engines, which are important subsystems of
microdisplay televisions, have been increasingly praised by industry analysts
for their high performance.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Recent
accolades for JDS Uniphase&#146;s light engines include a very favorable review of
image quality on both UltreX- and DefiniTV-driven displays and a &#147;Good Buzz&#148;
award at the May 25-27 Society for Information Display conference from Chris
Chinnock of Insight Media.&#160; Key image
quality attributes were described as excellent by David Mentley of iSuppli<b><font style="font-weight:bold;">, </font></b>in his review of the<b><font style="font-weight:bold;">  </font></b>Brillian 1080p RPTV which uses the UltreX
light engine. UltreX also received Laurin Publishing&#146;s Photonics Circle
of Excellence award for technical innovation.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In
addition to light engines, JDS Uniphase&#146;s portfolio of products for the display
market includes front surface mirrors, microdisplay windows for DLP imagers,
color wheels, and other coated optics and assemblies.</font></p>
