Scientific-Atlanta Comments on Shareholder Suits

Atlanta, GA – November 23, 2005. Scientific-Atlanta, Inc. (NYSE:SFA) today reported that it has received two purported class action lawsuits related to its announced acquisition by Cisco Systems, Inc. The complaints, which name both Scientific-Atlanta and its directors as defendants, were brought in Georgia state court and generally allege that the company’s directors and officers breached fiduciary duties owed to our shareholders in connection with the merger. The company believes that the complaints are without merit and intends to defend the actions vigorously.

The board of directors of Scientific-Atlanta engaged in a thorough and deliberative process to obtain the best transaction at the highest price available for its shareholders, culminating in the definitive merger agreement with Cisco, which was announced on November 18. As previously announced, Cisco is acquiring Scientific-Atlanta for $43 per share in cash in exchange for each share of Scientific-Atlanta, for an aggregate purchase price of approximately $6.9 billion.

The company will file a preliminary proxy statement with the SEC which will detail the process executed by its board of directors, including the receipt of fairness opinions from three nationally recognized financial advisors.
