ITEM 5.  OTHER EVENTS.

         On February 16, 2000 the Company issued a press release announcing the
estimated earnings for its 1999 fourth quarter. A copy of the press release is
attached hereto as Exhibit 99 and incorporated by reference herein.

         Some of the statements in this report and the press release attached
hereto are forward looking and related to anticipated future operating results.
Future operating results may be impeded by single or combined events and/or
circumstances that have not been presently anticipated. Forward-looking
statements are based on Landmark management's current expectations and
assumptions, which may be affected by a number of factors, including, without
limitation, the outcome of the current SEC accounting review, competitive
product introductions, price competition, any failure or delay in the Company's
ability to develop and introduce new products, seasonal factors affecting the
Company's sales, the Company's ability to attract and retain qualified
technical, sales, managerial and other key personnel, the Company's ability to
manage expenses effectively, the introduction of the Euro currency, the "Year
2000" software and systems issue, and other factors. Therefore, there can be no
assurance that actual future results will not differ materially from anticipated
results. Readers should refer to Landmark's disclosure documents filed with the
Securities and Exchange Commission for specific details on some of the factors
that may affect operating results.
