on July 5, 2005, indicating that the Company's market value of listed securities
is below the minimum $50 million requirement for continued listing on the

continued listing on the Nasdaq National Market System because the market
value of the Company's listed securities was below the minimum

Market System under Nasdaq Marketplace Rule 4450(b)(1)(A).

Research Frontiers filed a request for, and had, a hearing before the Nasdaq
Listing Qualifications Panel to appeal the Staff Determination Letter.

Qualifications Panel has determined to transfer the listing of the
Company's common stock from the Nasdaq National Market to the Nasdaq
