(1) James A. Davidson (the "Reporting Person") is a shareholder and a director of Silver Lake (Offshore) AIV GP LTD., which is the general partner of each of Silver Lake Technology Associates Cayman, L.P. and Silver Lake Technology Investors Cayman, L.P. Silver Lake Technology Associates Cayman, L.P. is the general partner of each of Silver Lake Partners Cayman, L.P. and Silver Lake Investors Cayman, L.P. As of August 2, 2005, Silver Lake Technology Investors Cayman, L.P., Silver Lake Partners Cayman, L.P. and Silver Lake Investors Cayman, L.P. (collectively, the "Silver Lake Funds") owned approximately 31.8% of the outstanding ordinary shares of New SAC. New SAC is the largest shareholder of Seagate Technology (the "Issuer") and beneficially owned 144,500,493 of the Issuer's common shares, par value $0.00001 per share (the "Common Shares"), prior to the transaction reported hereby and will beneficially own 100,000,493 of the Common Shares after the transaction reported hereby.
(2) The Reporting Person is also a member of New SAC's board of directors. Because of his affiliation with the Silver Lake Funds and as a director of New SAC, the Reporting Person may be deemed to have shared voting and dispositive power over the Issuer's Common Shares held by New SAC. The Reporting Person, however, disclaims beneficial ownership of any of the Issuer's Common Shares beneficially owned by New SAC, except to the extent of any pecuniary interest therein.
