Section 1 - Registrant's Business and Operations

Item 1.01 Entry into a Material Definitive Agreement

On May 21, 2012, Avistar Communications Corporation ("Avistar"), as borrower, entered into an amendment to the third amended and restated revolving credit promissory note agreement (the "Amendment") with JP Morgan Chase Bank, N.A. (the "Bank"), as lender. The Amendment relates to that certain credit facility previously described in Avistar's Current Report on Form 8-K filed with the Securities and Exchange Commission (the "SEC") on December 23, 2011. The third amended and restated revolving credit promissory note agreement (the "Agreement") provided a maximum line of credit facility amount of $8.0 million from December 22, 2011 through and including March 13, 2012, and then a reduced maximum line of credit facility of $6.0 million from and after March 14, 2012 through the maturity date on December 22, 2012.

The primary purpose of the Amendment was to modify the maximum line of credit facility amount for the entire period from May 21, 2012 through the maturity date to $7.0 million. As of May 21, 2012, the total principal amount borrowed by Avistar under the credit facility was $6.0 million.

The foregoing description does not purport to be complete and is qualified in its entirety by the terms and conditions of the Amendment, which is expected to be filed as an exhibit to Avistar's Quarterly Report on Form 10-Q for the quarter ending June 30, 2012.
