Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) The reporting person is the chairman of the board of directors of Seagate Technology (the "Issuer") and 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 forward contract reported hereby. As a director of New SAC, the reporting person may be deemed to beneficially own the securties 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 percuniary 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.
