Item 5.  Other Events.

     In December 1999, Medical Dynamics, Inc. (Nasdaq SmallCap-MEDY), a
nationwide provider of dental practice management software and integrated
technology solutions, announced 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. Effective as of May
22, 2000, MEDY and Infocure entered into an amendment to that agreement which
provided that Infocure may pay persons who hold 1,000 or fewer shares of Medical
Dynamics cash rather than issuing them shares of Infocure common stock if the
Merger is completed.

     On April 14, 2000, Infocure filed a registration statement on Form S-4 for
the contemplated transaction. The registration statement filed by Infocure
included MEDY's proxy statement for its special meeting of shareholders to
consider the transaction. Currently that meeting is scheduled for June 28, 2000,
with a record date for that meeting of April 27, 2000. The merger is subject to
approval by Medical Dynamics shareholders at a meeting.

         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.

     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.
