Dear, Bert

I want to let you know that I am very pleased with the results of the Heartbeat Of America Show that featured HyperBaric Systems. The Professional anchors and William Shatner as the host added Significantly to the value of the show for our purposes.

We have used the tapes of the show, both full and short versions, to mail to current and prospective investors. We have also put the tape on our website so that visitors to the site could view the film immediatly without waiting for the film to be sent by regular mail.We also have used outside investor relations and PR services that sent out e-mail notices to thousands of investors with a direct link to the show. This has saved us thousands of dollars of mailing and duplication costs, not to mention the time it would have taken to mail the tapes to that many people.

Thanks again for a job well done.
