Item 5. Other Events.

     Medical Dynamics, Inc. (Nasdaq SmallCap-MEDY), a nationwide provider of
dental practice management software and integrated technology solutions, today
announced it has completed a definitive merger agreement with InfoCure
Corporation (Nasdaq-INCX) by which InfoCure will acquire all outstanding Medical
Dynamics common stock in exchange for InfoCure common stock.

     Upon completion of the merger, one current share of Medical Dynamics common
stock will convert to .05672 shares of InfoCure common stock. This conversion
ratio will be subject to certain adjustments to the extent the price of InfoCure
common stock in the public market increases above $22.04 per share or decreases
below $13.22 per share. The merger is subject to approval by Medical Dynamics
shareholders at a meeting which will be called pursuant to a proxy statement,
expected to be included as part of a Form S-4 registration statement to be filed
by InfoCure.

     The definitive agreement replaces a letter of intent between the two
companies that called for Medical Dynamics to exchange approximately 60% of its
outstanding common stock for InfoCure's KComp general dental practice business
and $2 million in cash.

     Certain statements contained in this report may be forward-looking
statements. The accuracy of these statements cannot be guaranteed as they are
subject to a variety of risks including, but not limited to, future economic
conditions, competitive products and pricing, new product development, the
delivery of products under existing contracts and other factors.
