VITEX SYSTEMS SIGNS LICENSING AGREEMENT WITH ADVANCED NEOTECH SYSTEMS FOR ITS
GUARDIAN THIN-FILM ENCAPSULATION SYSTEM

Adoption of its Proprietary Barix™ Technology Continues to Grow Based on New Licensing Model

SAN JOSE, Calif., Oct. 25, 2006
– Vitex Systems, Inc. a leading technology developer, licensor and
development service provider for thin-film encapsulation and moisture barrier films, today announced that it
has signed a license agreement with Advanced Neotech Systems (ANS) Corporation of Korea. The
agreement includes a technology transfer package from Vitex to ANS, and gives ANS the non-exclusive
rights to make and sell Guardian™ thin-film encapsulation systems, which can be used in the manufacturing
of organic light emitting diode (OLED) displays. While the financial terms of agreement were not disclosed,
the license includes an upfront fee and on-going royalty payments based on tool sales.

“Thin-film encapsulation is the obvious trend for significant cost reduction and reduced thickness of OLED
displays on rigid substrates, and is a must for OLED displays on flexible substrate. Vitex is the leading
technology supplier in this field, and we are excited about our ongoing relationship with them,” said KB Bae,
president of ANS. “With the recent investment in our company by SNU Precision Co., Ltd. (www.snuprecision.
com) coupled with our license agreement with Vitex, we now have the financial strength and technological
capability to address the developing OLED display market. Moreover, the addition of Guardian to our
deposition equipment portfolio will allow us to be more competitive in the marketplace.”

Commenting on its agreement with ANS and licensing successes, Chyi-Shan Suen, director of sales and
marketing for Vitex, said, “ANS has been one of Vitex’s equipment partners for the past two years. Signing
this license agreement not only validates ANS’s confidence in Vitex’s Barix™ technology and IP portfolio
strength, but also reaffirms the growing adoption and need of our thin-film encapsulation technology to
enable future OLED displays.” He adds, “This announcement follows on the heels of a licensing agreement
signed in September with a major optical film manufacturer for our proprietary Flexible Glass technology,
which also illustrates the success of our new licensing model.”

Vitex’s Barix thin film encapsulation is an ultra-high barrier suitable for encapsulating OLED displays and
devices that are sensitive to moisture and oxygen, such as organic photovoltaics, organic solid state
lighting, thin-film batteries, etc. Considerable efforts are being devoted to develop these electronic devices
but have been impeded by the lack of thin-film barrier with adequate protection from moisture and oxygen,
until now. Vitex’s Guardian system allows display manufacturers to deposit, in-situ, a conformal Barix thin-
film barrier that is coated directly onto the device surface. As a result, electronic devices leveraging Barix
encapsulation can eliminate the costly and bulky mechanical encapsulation, both lowering manufacturing
costs and reducing the weight and thickness by up to 50 percent. When combined with Flexible Glass—a
thin, clear, flexible or conformable substrate with barrier properties equivalent to those of a sheet of glass—
the weight and thickness saving could be up to 90 percent.

About ANS
ANS Inc., headquartered in Pyungtaek, Korea, is a leading supplier of OLED deposition and encapsulation
mass production systems. Founded in 1998, ANS delivers high quality OLED mass production machines by
virtue of its core competence in areas such as efficient deposition sources, reliable shadow mask alignment,
and fully automated software control systems. ANS is developing new deposition sources to achieve even
better film uniformity and greater material utilization for large-size glass substrates. The deposition direction
can be in any orientation in the process chamber, therefore resolving the glass and mask bending issue. For

About Vitex Systems
Vitex Systems Inc., headquartered in San Jose, Calif., is commercializing transparent ultra-thin barrier films
for use in flat panel displays. The company’s proprietary encapsulation solution, Barix™, as well as its flexible
barrier substrate, enable the cost-effective production of organic light-emitting diode (OLED) displays that
are lighter in weight and thickness than any other commercially available displays. Vitex’s technology can also
be used to address a wide array of organic optoelectronics applications. The company was incubated at
Battelle, the world’s largest independent private non-profit research foundation, and was spun off as an
independent company in 1999. For more information on Vitex Systems, visit www.vitexsys.com.
