Item 2.  Acquisition or Disposition of Assets.
         -------------------------------------

         On June 30, 1998, Citrix Systems, Inc. (the "Company") completed its
         acquisition of all of the outstanding securities of APM Ltd. ("APM"), a
         company organized under the laws of England. APM, based in Cambridge,
         England, is engaged in consulting and development of application
         deployment, management and security products for Java. The Company
         intends to integrate the businesses of APM with the Company's existing
         operations.

         The transaction was valued at approximately US $41 million. The Company
         paid cash of approximately US $39 million and assumed net liabilities
         and transaction costs of approximately US $2 million. A substantial
         portion of the purchase price was allocated by the Company to in-
         process research and development for which the Company incurred a one-
         time charge to its operations, amounting to approximately US $34
         million, in the quarter ended June 30, 1998. The source of the funds
         used in this acquisition was the Company's working capital, and this
         acquisition was accounted for by the Company as a purchase. The
         purchase price and terms for the transaction were determined in arms-
         length negotiations.

         Forward-looking statements in this report are made pursuant to the safe
         harbor provisions of Section 21E of the Securities Exchange Act of
         1934. Investors are cautioned that statements in this press report
         which are not strictly historical statements, including, without
         limitation, statements regarding current or future financial
         performance, management's plans and objectives for future operations,
         product plans and performance, management's assessment of market
         factors, as well as statements regarding the strategy and plans of the
         Company and its strategic partners, constitute forward-looking
         statements which involve risks and uncertainties, including, without
         limitation, the successful and timely integration of APM into the
         Company and the Company's existing or future products, market
         acceptance of the Company's new or enhanced products, and the impact of
         competitive products and pricing, in addition to risks associated with
         the Company's reliance upon its strategic relationships with Microsoft
         and other strategic partners, dependence upon broad-based acceptance of
         the Company's ICA protocol, management of growth, the possibility of
         undetected software errors, and dependence on proprietary technology.
         For a more detailed description of the risk factors associated with the
         Company, please refer to the Company's 1997 Form 10-K and its Form 10-Q
         for the quarter ended March 31, 1998 filed with the Securities and
