(1) On November 17, 2008 and November 18, 2008, i-STT Investments (Bermuda) Ltd. ("i-STT Bermuda") settled its obligations under a pre-paid forward purchase agreement (the "Purchase Agreement") that was entered into on November 9, 2005 with Credit Suisse First Boston Capital LLC ("CSFB Capital"), an unaffiliated third-party purchaser. The Purchase Agreement obligated i-STT Bermuda to deliver up to 4,300,000 shares of Common Stock (or, at i-STT Bermuda's option, an equivalent amount of cash) to CSFB Capital on November 17, 2008 (the "First Settlement Date") and November 18, 2008 (the "Second Settlement Date" and, together with the First Settlement Date, the "Settlement Dates"), with 50.0% of the shares to be delivered on the First Settlement Date and 50.0% of the shares to be delivered on the Second Settlement Date.
(2) On November 16, 2005, i-STT Bermuda received $125,280,402.79 in net proceeds (after payment of $4,597,560 in underwriter compensation) from CSFB Capital as consideration for its obligations under the Purchase Agreement. Under a collateral agreement with CSFB Capital and Credit Suisse First Boston LLC, as collateral agent, i-STT Bermuda pledged 4,300,000 shares of Common Stock (the "Pledged Shares") to CSFB Capital to secure the performance of its obligations under the Purchase Agreement.
(3) The Purchase Agreement provided that the total number of shares of Common Stock delivered to CSFB Capital on the Settlement Dates would be determined as follows: (a) if the average of the volume weighted average price per share of Common Stock on each of the 20 trading days immediately prior to, but not including, the second trading day preceding November 15, 2008 (the "Averaged Trading Value") was less than or equal to $35.64 (the "Initial Price"), i-STT Bermuda would deliver to CSFB Capital all of the Pledged Shares; (b) if the Averaged Trading Value was greater than the Initial Price, but less than or equal to $42.06 (the "Cap Price"), i-STT Bermuda would deliver to CSFB Capital an amount of Pledged Shares equal to the total number of Pledged Shares multiplied by a fraction equal to the Initial Price divided by the Averaged Trading Value; and (c) if the Averaged Trading Value was greater than the Cap Price, i-STT Bermuda would deliver to CSFB Capital 3,643,820 Pledged Shares.
(4) In connection with the settlement, on November 14, 2008, the Averaged Trading Value was calculated to be $58.65. Accordingly, on each of the Settlement Dates i-STT Bermuda delivered to CSFB Capital 1,821,910 Pledged Shares (a total of 3,643,820 shares of Common Stock), and retained ownership of the remaining 656,180 Pledged Shares, which were released from the pledge on the Second Settlement Date.
(5) i-STT Bermuda is the record holder of the securities of the Issuer reported herein. i-STT Bermuda is a wholly-owned subsidiary of i-STT Investments Pte. Ltd. ("i-STTI"), which is a wholly-owned subsidiary of STT Communications Ltd ("STT Comm"), which is a wholly-owned subsidiary of Singapore Technologies Telemedia Pte Ltd ("STT"), which is a wholly-owned subsidiary of Temasek Holdings (Private) Limited ("Temasek"). By virtue of the foregoing relationships, each of i-STTI, STT Comm, STT and Temasek may be deemed to have an indirect interest in the securities reported herein. Temasek disclaims beneficial ownership of such securities except to the extent of its pecuniary interest therein.
