(the Exchange) has determined to remove from listing the common stock of
Avistar Communications Corporation (the Company), effective at the open
of business on August 31, 2009.  Based on a review of information

shares would be delisted unless it requested a hearing.  On December 30,
2008, the Company excercised its right to appeal the Exchange Staffs
determination to the Listing Qualifications Hearings Panel (Panel)
pursuant to Rule 5815(a)(1)(A). Upon review of the information provided
by the Company, by decision dated April 2, 2009 the Panel determined to
grant an extension to the Company until June 22, 2009.  On June 3, 2009,
the Company requested that the Panel grant it an extension beyond June 22,
2009.  On June 12, 2009, the Panel issued a decision affirming its April 2,
2009 decision.  On June 17, 2009, the Company exercised its right to appeal
the June 12, 2009 Panel decision to the Nasdaq Listing and Hearing Review
Council (the Council) pursuant to Rule 5820(a). The Companys securities
