Item 2.01. Completion of Acquisition or Disposition of Assets.

     On August 15, 2005, Citrix Systems, Inc., a Delaware corporation
("Citrix"), completed its previously announced acquisition of NetScaler, Inc., a
privately held Delaware corporation headquartered in San Jose, California
("NetScaler"), pursuant to an Agreement and Plan of Merger, dated as of June 1,
2005, by and among Citrix, NCAR Acquisition Corporation, a Delaware corporation
and a wholly owned subsidiary of Citrix, NCAR, LLC, a Delaware limited liability
company and a wholly owned subsidiary of Citrix, NetScaler, and Gaurav Garg, as
stockholder representative (the "Merger Agreement"). The purchase price was
approximately $300 million, payable approximately 45% in cash and approximately
55% in Citrix stock, plus the assumption of approximately $23 million in
unvested stock options. $44 million of the purchase price was placed in escrow
as security for the indemnity obligations under the Merger Agreement. Prior to
the merger, neither NetScaler nor its stockholders had any material relationship
with Citrix, its subsidiaries, or its affiliates, officers or directors or any
associate of any of its officers or directors.

     The foregoing description of the transaction does not purport to be
complete and is qualified in its entirety by reference to the complete text of
the Merger Agreement, which was previously filed with Citrix's Quarterly Report
on Form 10-Q on August 9, 2005 and incorporated herein by reference as Exhibits
2.1 and 2.2 hereto.
