3dfx developed high performance, cost-effective graphics chips, graphics boards, software and related technology that enabled an interactive and realistic 3D experience across multiple hardware platforms, but is now in the process of winding up its business. As discussed below, on March 27, 2001, 3dfx's shareholders approved proposals to liquidate, wind up and dissolve 3dfx pursuant to a plan of dissolution and to sell certain of its assets to Nvidia US Investment Company ("Nvidia Sub"), a wholly owned subsidiary of Nvidia Corporation ("Nvidia"). 3dfx is continuing to wind up its affairs and dissolve.
