ITEM 8.01. OTHER EVENTS

Rule 10b5-1(c) promulgated under the Securities Exchange Act of 1934 provides an

plan for trading securities of an issuer when that that person is not aware of
material nonpublic information concerning such issuer.

On November 28, 2005, each of John Pappajohn, chairman of the board and
secretary of Healthcare Acquisition Corp. (the "Company"), Derace L. Schaffer,
MD, the Company's chief executive officer, and Matthew P. Kinley, the Company's
president, entered into a written individual purchase plan, with Citigroup
Global Markets ("CGM"), complying with Rule 10b5-1(c) for the purchase of the
Company's publicly traded warrants that are exercisable for shares of the
Company's common stock . Under such purchase plans, commencing November 29,
2005, CGM may purchase specified amounts of the Company's warrants during a
specified period and in accordance with price ranges and other terms specified
by such officers.
