Dell, Inc. (DELL) has reached Tuesday an agreement with activist investor Carl Icahn for limiting the his stake in the beleaguered personal computer maker to 10 percent. A special committee reporting to Dell's board expects the deal to help produce a superior proposal from Icahn while also protecting shareholders against potential accumulation of an unduly influential voting interest. In return, the agreement provides Icahn entities a limited waiver under Section 203 of the Delaware General Corporation Law which facilitates Icahn's ability to engage with other Dell stockholders. However, Dell, which agreed in February to be taken private in a $24.4 billion deal, say Icahn cannot make any deals with other shareholders who together would collectively own more than 15 percent of Dell's shares.
