CA ADOPTS NEW STOCKHOLDER PROTECTION
RIGHTS AGREEMENT

Will Bring Plan to Stockholders for Vote at 2007 Annual Meeting

ISLANDIA, N.Y., October 16, 2006 – CA (NYSE: CA) today announced that its Board of Directors has unanimously adopted a Stockholder Protection Rights Plan. In response to feedback from CA stockholders and to address corporate governance concerns associated with rights plans, CA will ask its stockholders to vote on its Rights Plan at its 2007 Annual Meeting.

In connection with the adoption of the Rights Plan, the Company declared a dividend of one right on each outstanding share of CA’s common stock. The dividend will be paid on November 30, 2006 upon expiration of CA’s existing rights plan to stockholders of record on October 26, 2006. The Rights Plan was not adopted in response to any specific effort to acquire control of the Company and is not intended to prevent a takeover at a full and fair price.

In addition to the customary “flip-in” and “flip-over” provisions, the Rights Plan includes a number of features adopted in response to recommendations by stockholders, including setting the threshold for triggering exercise of the Rights Plan at 20 percent of the outstanding shares rather than 15 percent; a fixed term for the Rights Plan of only three years instead of ten; and a provision requiring a committee of independent directors to assess annually whether the Rights Plan remains in the best interests of CA’s stockholders. The Rights Plan also includes a provision that states that the Rights Plan will not be triggered by a “Qualifying Offer” if holders of at least 10 percent of the outstanding shares of common stock request that a special meeting of stockholders be convened for the purpose of exempting such offer from the Rights Plan, and thereafter the stockholders vote at such meeting to exempt such “Qualifying Offer” from the Rights Plan.

“CA believes this Rights Plan, which has features similar to those approved by stockholders at other companies, strikes an appropriate balance

between empowering the Board of Directors to use a Rights Plan to increase its negotiating leverage to maximize stockholder value and the current best practices in corporate governance that give stockholders a voice in such process,” said Lewis Ranieri, chairman of the Board of Directors. “The ‘Qualifying Offer’ provision of the Rights Plan provides our stockholders the ability to express their preference for or against the offer while also providing our Board with the time to attract and secure potentially superior alternatives to maximize stockholder value. In addition, the annual review of the Rights Plan by independent directors is intended to ensure that the Rights Plan only remains in place if it continues to be in the best interests of the Company and its stockholders.”

Additional details and a copy of the Rights Plan are included in a Report on Form 8-K filed with the Securities and Exchange Commission on October 16, 2006.
