(1) The reporting person is the President, chief executive officer and a director of Seagate Technology (the "Issuer") and also is a member of the board of directors of New SAC. New SAC is the controlling shareholder of the Issuer. New SAC entered into and delivered under the futures contract reported hereby. As a director of New SAC, the reporting person may be deemed to beneficially own securities held by New SAC. The reporting person, however, disclaims beneficial ownership of any of the securities beneficially owned by New SAC, except to the extent of any pecuniary interest therein.
(2) On January 3, 2005, New SAC rehypothecated 30,000,000 of Seagate Technology's common shares, par value $0.00001 per share (the "Shares"), satisfying its delivery obligation under a forward sale agreement with Goldman Sachs Financial Markets, L.P. ("GSFM"). At the same time, New SAC transferred to GSFM all voting, dividend and economic rights to the Shares in accordance with the terms of the forward sale agreement. The transaction is reflected in Table I as the disposition of the underlying Shares and in Table II as the settlement of the futures contract. On the same date, New SAC received payment for the Shares in accordance with the terms of the forward sale agreement.
(3) Options granted to the Reporting Person under the Issuer's 2001 Share Option Plan are subject to a four-year vesting schedule. One quarter of the option shares vested on November 22, 2001. The remaining option shares are fully vested and vested proportionally each month over the 36 months following November 22, 2001.
(4) Options granted to the Reporting Person under the 2001 Share Option Plan are subject to a six-year vesting schedule as follows. 200,000 of the option shares will vest on February 14, 2005. 250,000 option shares will vest proportionally on a monthly basis over the one-year period from February 14, 2005 to February 14, 2006. 300,000 option shares will vest proportionally on a monthly basis over the one-year period from February 14, 2006 to February 14, 2007. 350,000 option shares will vest proportionally on a monthly basis over the one-year period from February 14, 2007 to February 14, 2008. 400,000 option shares will vest proportionally on a monthly basis over the one-year period from Febraury 14, 2008 to February 14, 2009.
