ITEM 5. INTEREST IN SECURITIES OF THE ISSUER Item 5 is hereby amended as follows: i-STT Bermuda has the power to vote 4,300,000 shares of Common Stock representing 15.8 % of the outstanding shares of Common Stock. Because of the relationships described in Item 2 above, the direct and indirect parents of i-STT Bermuda may be deemed to beneficially own the shares which i-STT Bermuda has the power to vote. Temasek disclaims beneficial ownership of these shares. In addition to the share amounts detailed in the preceding paragraph, Temasek may be deemed to beneficially own 11,718 additional shares of Common Stock, representing 0.04 % of the outstanding shares of Common Stock. The additional 11,718 shares of Common Stock are owned beneficially and of record by Temasek's indirect, wholly-owned subsidiary, T.H.e Venture Pte Ltd. On November 16, 2005, i-STTI completed a sale of 5,889,549 shares of Common Stock to the public, including 739,549 shares of Common Stock sold pursuant to the exercise of an overallotment option, and received $202,032,144.12 in net proceeds (after payment of $7,871,382.24 in underwriter compensation).

The calculation of the percentages in the foregoing paragraphs is based on the number of shares of Common Stock disclosed as outstanding as of September 30, 2005, in the Form 10-Q filed by the Issuer on October 26, 2005 and the number of shares of common stock issued upon the conversion of 3,074,919 shares of the Issuer's series A preferred stock held by i-STTI on November 9, 2005 (i.e. an aggregate of 27,263,658 shares of Common Stock).
