        <footnote id="F1">This option was canceled pursuant to an Agreement and Plan of Merger, dated as of August 2, 2005, among Chart Industries, Inc., CI Acquisition, Inc. (the &quot;Buyer&quot;), certain stockholders of Chart Industries, Inc. and First Reserve Fund X, L.P. in exchange for a cash payment of $43,400, representing the difference between the exercise price of the option and the per share consideration paid by the Buyer for the underlying Chart Industries common stock on the effective date of the merger ($64.75 per share).  This disposition was approved as a transaction exempt under Rule 16b-3 by the Board of Directors of Chart Industries.</footnote>
        <footnote id="F2">The option was granted to Michael P. Harmon, a director of the Issuer and a Senior Vice President of Oaktree Capital Management, LLC (&quot;Oaktree&quot;), which is the general partner of OCM Principal Opportunities Fund II, L.P. (the &quot;Fund&quot;). Pursuant to Oaktree's policies and an agreement between Mr. Harmon and the Fund, Mr. Harmon is deemed to hold the reported option for the benefit of the Fund, and must exercise the option solely upon the direction of the Fund, which is entitled to the shares issued upon exercise.</footnote>
        <footnote id="F3">Oaktree is a limited liability company managed by an executive committee, the members of which are Howard S. Marks, Bruce A. Karsh, Sheldon M. Stone, D. Richard Masson, Larry W. Keele, Stephen A. Kaplan, Russel S. Bernard, John B. Frank, David Kirchheimer and Kevin L. Clayton. Each of such persons and Oaktree may be deemed indirect beneficial owners of the option. Except to the extent of their respective pecuniary interest, each of such persons and Oaktree disclaim beneficial ownership of the securities reported herein and the filing of this Form 4 shall not be construed as an admission that any such person is the beneficial owner of any securities covered by this Form 4.</footnote>
    </footnotes>

    <remarks>This report is filed jointly by the Fund and Oaktree, each of whom were 10% owners. The Fund may also be deemed a director by virtue of the fact that Mr. Michael Harmon, a representative of the Fund, served on the Issuer's board of directors at the request, and for the benefit, of the Fund.</remarks>
