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
June 22, 2000, MEDY and Infocure entered into an amendment to that extended the
outside completion date from July 31, 2000 until August 31, 2000, and extended
other dates in the agreement comparably. In addition, the parties had earlier
cancelled the previous amendment announced in Form 8-K dated May 22, 2000, which
had provided that Infocure had the right to pay cash to persons holding a
limited number of shares of Medical Dynamics.

     On April 14, 2000, Infocure filed a registration statement on Form S-4 for
the contemplated transaction and filed an amendment thereto on June 20. 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 July 31, 2000, with a record date for that meeting of
June 9, 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.

     THIS SECOND AMENDMENT TO THE PLAN AND AGREEMENT OF MERGER by and among

     WHEREAS, pursuant to the terms of the Merger Agreement, as amended by that
certain First Amendment to the Plan and Agreement of Merger dated April 10,
2000, Merger Sub shall merge with and into Company; and

     WHEREAS, the parties desire to further amend the Merger Agreement.

     NOW, THEREFORE, Company, Parent and CADI hereby agree to amend the Merger
Agreement as follows:

     1. Change in Termination Date. Section 8.1.B. of the Merger Agreement is
hereby amended to delete Section 8.1.B. in its entirety and to insert in lieu

                    "8.1.B. By either Company or Parent if the Merger shall not
                    have been consummated by August 31, 2000 for any reason;
                    provided, however, that the right to terminate this
                    Agreement under this Section 8.1.B. shall not be available
                    to any party whose action or failure to act has been a
                    principal cause of or resulted in the failure of the Merger
                    to occur on or before such date and such action or failure
                    to act constitutes a breach of this Agreement."

     Except as modified herein, the terms and conditions of the Merger Agreement
shall remain in full force and effect.
