Item 1.01.              Entry into a Material Definitive Agreement.

On April 7, 2005, Computer Associates International, Inc., a Delaware corporation (“Computer Associates”), Minuteman Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of Computer Associates (the “Merger Sub”), and Concord Communications, Inc. (“Concord”), a Massachusetts corporation, entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which the Merger Sub will merge with and into Concord, with Concord as the surviving corporation (the “Merger”). As a result of the Merger, Concord will become a wholly owned subsidiary of Computer Associates.

Pursuant to the Merger Agreement, at the effective time of the Merger, each outstanding share of common stock, $0.01 par value, of Concord (other than any such shares owned by Computer Associates, Concord, or Merger Sub, or by any Concord stockholders who are entitled to and properly exercise dissenter’s rights under Massachusetts law) shall be converted into the right to receive $17.00 in cash, without interest.  Additionally, at the effective time of the Merger, each outstanding option to purchase common stock of Concord, whether vested or unvested, will be assumed by Computer Associates and become an option to acquire shares of common stock of Computer Associates, on the terms and conditions set forth in the Merger Agreement.  The aggregate amount of consideration to be paid by CA to Concord shareholders pursuant to the Merger is approximately $330 million.  CA will also assume approximately $20 million in net debt from Concord pursuant to the Merger.

Consummation of the Merger is subject to customary conditions, including, among others, (i) the adoption of the Merger Agreement by the stockholders of Concord, (ii) the termination or expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (iii) the absence of any governmental action or proceeding (A) challenging or seeking to restrain or prohibit the consummation of the Merger or (B) seeking to prohibit or materially impair CA's ability to operate any of the material businesses or assets of CA or Concord or prohibit or limit in any material respect CA's ability to exercise certain ownership rights with respect to Concord after the effective time and (iv) the absence of any law or order having any of the effects referred to in (A) or (B) of clause (iii) above.  In addition, each of CA's and Concord's obligation to consummate the Merger is subject to certain other conditions, including, among others, (i) the accuracy of the representations and warranties of the other party (subject to certain exceptions) and (ii) material compliance of the other party with its covenants. 

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is incorporated by reference herein.
