CVD Diamond Product Line

In addition to the Shareholders' Meeting Results and Board of Director
Appointments, the Company is also introducing its new line of chemical vapor
deposition (CVD) diamond substrates for the infrared optics (IR) market. For
more than 20 years, the Company has been producing CVD zinc selenide (ZnSe) and
zinc sulfide (ZnS) for IR optical applications. The Company's expertise in CVD
crystal growth accelerated the development program for synthesizing high quality
CVD diamond material tailored specifically for optical applications. The
Company's Wide Bandgap Materials (WBG) Group's experience with fabricating
super-hard silicon carbide (SiC) facilitated the Company's development program
for optically finishing our CVD diamond substrates. The Company also has many
years of experience in coating customer-supplied diamond substrates with low
absorption antireflective and partially reflective coatings for high power laser
applications.

Diamond's unique properties provide solutions where other materials are not
sufficient. Diamond has superior thermal conductivity for dissipating heat
associated with high power lasers and electronics. Diamond's low thermal
expansion coefficient and extreme hardness prevents typical mounting stress
associated with extreme temperatures. With optical transparency ranging from UV
to microwave wavelengths, diamond is ideal for a multitude of optical
applications. Other applications where diamond's exceptional properties are
beneficial include water treatment, medical dosimetry, high power and high
frequency electronic devices, heat sinks and spreaders and surgical instruments.

The introduction of the CVD diamond substrates broadens the Company's diamond
materials offerings to now include both optical and industrial grades. On July
1, 2009, the Company announced the formation of a joint venture with Beijing
Supower Science and Technology Developing Co., Ltd. The new company, Langfang
Haobo Diamond Co., Ltd., will produce industrial grade CVD diamond for cutting
and wear applications.
