        <footnote id="F1">In connection with the Issuer's initial public offering on July 25, 2006, the Issuer declared a stock dividend payable to the holders of record of the Issuer's Common Stock issued and outstanding on July 25, 2006 (the &quot;Record Date&quot;).  The payment of such stock dividend was contingent upon whether the underwriters in the Issuer's initial public offering exercised their option to purchase up to an additional 1,875,000 shares of Common Stock (the &quot;Over-Allotment Option&quot;) on or prior to August 24, 2006 (the &quot;Expiration Date&quot;).  The underwriters did not purchase any of the 1,875,000 shares of Common Stock under the Over-Allotment Option prior to the Expiration Date, and on August 25, 2006, the Issuer distributed the stock dividend of 1,875,000 shares ratably to the holders of its Common Stock as of the Record Date. The reporting person received 4,097 shares of the Issuer's Common Stock pursuant to the stock dividend.</footnote>
        <footnote id="F2">The number of derivative securities reported on this Form 4 represents the total number of options issued to the reporting person on November 23, 2005 as adjusted in accordance with applicable tax rules and a 9.95928-for-one stock adjustment for the shares underlying options, which occured immediately prior to to the closing of the Company's initial public offering.  The number of derivative securities was previously reported on the reporting person's Form 3, dated July 25, 2006, based on an assumed adjustment ratio which corresponded to the mid-point of an estimated price range of the initial public offering, which was slightly higher than the actual adjustment ratio, as determined subsequent to the filing of the Form 3.</footnote>
        <footnote id="F3">These options were granted on November 23, 2005 pursuant to the terms of the Chart Industries Inc. Amended and Restated 2005 Stock Incentive Plan.  The options vest annually in equal installments over five years based on continued service.  These options, as adjusted, are exercisable at a price of $6.50 per share.</footnote>
