(1) William D. Watkins (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 and owned 252,500,000 of the Issuer's common shares, par value $0.00001 per share (the "Common Shares"), prior to the transaction reported hereby and will own 239,500,000 of the Common Shares after the transaction reported hereby. 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.
(2) The Common Shares disposed of by New SAC through the transaction reported hereby were sold pursuant to Rule 144 under the Securties Act of 1933, as amended.
