        <footnote id="F1">On December 3, 2007, Mr. Fuller amended and extended the previously reported  Variable Prepaid Forward contract he entered into with Credit Suisse First Boston Capital LLC on December 1, 2004 relating to 337,500 shares of Genesee &amp; Wyoming, Inc. (&quot;GWI&quot;) Common Stock (originally 150,000 shares of GWI Common Stock, adjusted for subsequent stock splits), which contract was originally scheduled to expire on December 3, 2007.  The amended contract extended the term of the contract to December 24, 2008 and reset the Cap Price and Floor Price per share.  Mr. Fuller received net proceeds of $623,142 in connection with the amendment and extension.</footnote>
        <footnote id="F2">Under the terms of the amended contract, Mr. Fuller has agreed to deliver shares of Class B Common Stock (which are immediately convertible into shares of Class A Common Stock on a one-for-one basis) or shares of Class A Common Stock on the expiration date of the contract (or on an earlier date if the contract is terminated early) as follows: (i) if the Final Price is less than or equal to the Floor Price ($26.3449 per share), 337,500 shares; (ii) if the Final Price is less than or equal to the Cap Price ($31.6139 per share), but greater than the Floor Price, then a number of shares equal to 337,500 times the Floor Price divided by the Final Price; and (iii) if the Final Price is greater than the Cap Price, then a number of shares equal to 337,500 shares multiplied by a fraction, the numerator of which is the sum of the Floor Price and the difference between the Final Price and the Cap Price, and the denominator of which is the Final Price.</footnote>
        <footnote id="F3">In connection with the amended contract, Mr. Fuller has pledged 337,500 shares of Class B common stock to secure his obligation under the contract.  Under the contract, in lieu of delivery of shares, Mr. Fuller may, at his option, settle the contract by delivery of cash.</footnote>
