Research Frontiers Licenses SmartGlass International to Make SPD-Smart Architectural Window Products

Research Frontiers Incorporated (Nasdaq: REFR) and SmartGlass
International Ltd. announced today that SmartGlass International Ltd.
has acquired a non-exclusive license to use Research Frontiers'
patented SPD-Smart(TM) light-control technology for architectural
smart windows, skylights and similar products in the United Kingdom
and Republic of Ireland. The minimum annual royalties and other
license terms were not disclosed.

SmartGlass International's SPD-Smart products can be manually or
automatically "tuned" to precisely control the amount of light, glare
and heat passing through glass or plastic. These products foster
innovative building design opportunities never before available.

Glass facades using patented SPD light-control technology reduce
the need for air conditioning during the summer months and heating
during winter. The ability to instantly switch the glass to maximize
daylight when it's really needed and to provide controllable solar
shading during peak light conditions is unique.

John Browne, Executive Director of SmartGlass International,
noted: "The use of intelligent glass provides added value and
increased flexibility in new building design, improves working
environments and buildings ergonomics, saves energy, and increases the
well being of building occupants. As a company dedicated to bringing
environmentally friendly "green" building products and unique design
abilities to our customers, we are pleased to now have the expanded
resources through the merger of the smartglass businesses of
SmartGlass Ireland and Vision (Environmental Innovation) Ltd. Under
license from Research Frontiers, we can now offer SPD-Smart products
over a wider geographic area, and we plan continued expansion of this
very attractive line of our business. SmartGlass International
believes with the recent announcement of stringent legislation on the
reduction of CO2 emissions, and the availability of wide-width
SPD-Smart film, the architectural smart glass market is set to grow at
a significant rate over the next five years." Further details can be
