the placement agent a three-year warrant to purchase a number of shares of
our common stock equal to the quotient of (i) $160,980 (representing 3% of
the gross proceeds of this transaction) over (ii) the closing price of our
common stock on the American Stock Exchange on the date of the closing of
this transaction, which warrant will have an exercise price per share equal
to 120% of the closing price of our common stock on the American Stock
Exchange on the date of closing of this transaction. We expect this
transaction to close on March 28, 2000. We will not pay any other
compensation in conjunction with this sale of our common stock. We have
agreed to indemnify the placement agent against liabilities, including
liabilities under the Securities Act of 1933.

RECENT DEVELOPMENTS

incorporation at the 1998 Annual Meeting of Stockholders.

nationwide coverage for Medicare patients receiving TMR with devices approved by

memorandum recommending that Medicare provide coverage for TMR procedures
performed with FDA approved devices.
