Research Frontiers Sells New License To AGC Flat Glass Europe to Manufacture and Offer SPD-Smart Architectural Windows

Research Frontiers Inc. (Nasdaq: REFR) has sold a new license to
AGC Flat Glass Europe SA to offer architectural smart windows using
Research Frontiers´ patented SPD-Smart(TM) light-control film. When
integrated with windows, skylights, light tubes, doors, interior
partitions and other products, SPD-Smart film gives users the ability
to rapidly, precisely and uniformly control the amount of light, glare
and heat passing through glass or plastic.

AGC Flat Glass Europe (formerly Glaverbel SA) is the European flat
glass branch of AGC (Asahi Glass Company), the world´s largest
glassmaking group. The company is a growth-oriented, customer-focused
company highly regarded globally for its innovative products. The new
non-exclusive worldwide license agreement with AGC Flat Glass Europe,
which renews and replaces Glaverbel´s prior license agreement,
provides for a 5-10% royalty payable to Research Frontiers on sales of
licensed products. Other license provisions, including fees and
minimum annual royalties payable to Research Frontiers, were not
disclosed.

SPD light-control technology is protected by over 500 patents and
patent applications held by Research Frontiers Inc., the developer and
licensor of the technology to be used in AGC Flat Glass Europe´s smart
window products. As well as instant light control benefits, SPD-Smart
products reduce outside noise, provide greater security for both
privacy and structural integrity, and protect interiors and occupants
from heat and harmful ultraviolet radiation.

In addition to being an environmentally friendly "clean
technology" because of its potential daylighting and energy savings
advantages, SPD-Smart windows provide empowering quality-of-life and
aesthetic benefits by offering control over the environment to suit
one´s preference. These windows, skylights and other glazings can be
optically clear, block over 99% of visible light, and are tunable
manually or automatically to any level of light transmission between
dark and clear. All of this is done instantly regardless of the window
size - advantages that other competitive smart window technologies,
such as liquid crystal or electrochromics, cannot offer.
