    Research Frontiers Incorporated Common Stock Listing
to Move from Nasdaq National Market to Nasdaq SmallCap Market

Woodbury, NY - September 15, 2005 - Research Frontiers
Incorporated (Nasdaq:REFR) today announced that it has
received a determination from the Nasdaq Listing Qualifications
Panel to transfer the listing of the Company's common stock from the
Nasdaq National Market to the Nasdaq SmallCap Market.
Effective with the open of business on Friday, September 16, 2005,
Research Frontiers common stock will trade on the Nasdaq SmallCap
Market under its current symbol "REFR".

The determination followed a Nasdaq Staff Determination Letter
received by Research Frontiers on August 8, 2005 indicating that
Research Frontiers common stock is no longer eligible for continued
listing on the Nasdaq National Market System because the market
value of the Company's  listed securities was below the minimum
$50 million requirement for continued listing on the NASDAQ
National Market System under Nasdaq Marketplace Rule 4450(b)(1)(A).
