Item 1.01. Entry into a Material Definitive Agreement.



On January 25, 2010, Vision Systems of Brignais, France announced that it has
acquired a non-exclusive license from Research Frontiers Inc. (Nasdaq:REFR) to
manufacture and sell in all countries of Europe SPD-Smart products for
aircraft, trains, recreational vehicles, busses, trucks, mobile cranes
and construction vehicles.

The license provides for a 15% royalty to Research Frontiers on sales of
licensed SPD-Smart products including windows, partitions, cabin dividers,
sunroofs and shades. The minimum annual royalties and other license terms
were not disclosed.

When integrated with transportation vehicle and aircraft window products,
SPD-Smart film gives users the ability to rapidly, precisely and uniformly
control the amount of light, glare and heat entering the vehicle. SPD-Smart
products can be optically clear, block over 99.5% of visible light, and
are tunable manually or automatically to any level of light transmission
between clear and dark. All of this is done instantly and uniformly
regardless of the size of the window - advantages that other smart window
technologies, such as liquid crystals or electrochromics, cannot offer.

Due to its ability to block heat as well as visible light, SPD-SmartGlass(tm)
can reduce vehicle interior heat build-up. These eco-friendly products also
can reduce the size of air conditioning systems and thus save weight and fuel.
In addition, they are automatically in the most energy efficient, heat-blocking
state when the engine is off, which results in the aircraft or vehicle being
cooler when not in use and upon the entering of operators or passengers. They
provide greater security due to on-demand privacy capability, increase
passengers' comfort, and protect passengers and interiors from heat and harmful
ultraviolet radiation. SPD-Smart technology empowers users by offering rapid,
real-time control over the environment to suit one's preference or requirements.

Catherine Robin, Senior VP for Business Development of Vision Systems commented:
"Our products are focused on innovation and are designed to ensure competitive
advantage to all our customers both on value and quality performance. We have
been receiving an increasing number of client requests regarding combined
solutions for solar protection, and the time has come to incorporate SPD-Smart
film into our product line to make it smarter and in order to achieve our
clients' expectations. Vision Systems is well known in the Aeronautic and
Automotive fields and is a qualified first-tier supplier. Our mission is to
be 'Architects of Innovations' and SPD technology supports this very well."

Joseph M. Harary, President and CEO of Research Frontiers, noted: "In 2009, the
SPD industry's supply chain infrastructure experienced a steady stream of
important developments from large multinational companies licensed by Research
Frontiers, such as Hitachi Chemical's announcement that they commenced
mass-production of wide-width SPD film at a new production facility. We
are extremely pleased that Vision Systems is adopting SPD technology for use
in their impressive product lines across multiple industries. Their becoming
involved with our high-performing SPD-Smart light-control technology continues
this trend of ever-larger resources being devoted in our growing industry,
and of SPD-Smart technology becoming the smart glass of choice."
