thirty minute television shows that feature businesses in a news magazine style

Heartbeat's television studio in Southern California for a "breaking news"
interview taped on Heartbeat's news set and conducted by one or more of
Heartbeat's anchors. HyperBaric will arrive the day before the shoot for a
script conference. The date for this studio interview will be set at a time
convenient for both Heartbeat and HyperBaric. Heartbeat, at its option, may
repeat portions of the show for the benefit of the viewers who tune in late. The
script will be completed in approximately two months from the date of this
Agreement and the Show and Videos described in Paragraph 5 will be completed
approximately two months after the script is completed. Heartbeat shall use best
efforts to incorporate HyperBaric's comments into the script.

cable or satellite within three months after completion of Show, the exact date,
time and channel to be determined by Heartbeat.

        The thirty-minute television Show shall be the property of Heartbeat.
Heartbeat and HyperBaric shall split equally any revenues derived from the sales
of the Show for a period of ten years from the date of this Agreement.
HyperBaric shall also have the unlimited right to use and duplicate the tape of
the Show without any payment of royalty or license for its use in marketing and
promotion as long as the tape is not sold commercially or used for television
broadcast purposes.
