            (d)       No person other than the Reporting Person or members of its Board of Directors is known to have the right to receive or the power to direct receipt of dividends from, or the proceeds of sale of, the Shares of IOT held by the Reporting Person, except Metropolitan Bank as to approximately 169,550 Shares held by Metropolitan Bank pursuant to an accommodation pledge of such Shares.

            (e)       Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

            Item 6 of the Amended Statement is hereby further amended by adding the following in replacement of the second paragraph under Item 6.

            Of the Shares owned by TCI, 159,816 Shares are held in a brokerage account at Brown & Co., 1,302,648 Shares are held in a brokerage account at First Southwest, 169,550 Shares are located at Metropolitan Bank and the balance of such Shares are held in nonbank financial institutions all of which may be deemed to be “collateral” for borrowings pursuant to margin or other account arrangements which are standard arrangements involving margin securities of up to a specified percentage of the market value of the Shares and bear interest at varying rates and contain only standard default and similar provisions, the operation of any of which should not give any person immediate voting power or investment power over such securities. Such arrangements exist with the Shares and other securities held in such accounts and it is impracticable at any time to determine the amounts, if any, with respect to such Shares and interest costs under such arrangements vary with applicable costs and account balances.

            Except as set forth in the preceding paragraph, the Reporting Person does not have any contracts, arrangements, understandings or relationships (legal or otherwise) with any person with respect to any securities of the Issuer including finders’ fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, divisions of profits or losses, or the giving or withholding of proxies.

Item 7. Material to be Filed as Exhibits.

            None.
