(1) Due to the Amended and Restated Stockholders Agreement, dated as of February 15, 2012, as amended and supplemented (the “Stockholders Agreement”), by and among GSE Holding, Inc., a Delaware corporation (the “Issuer”), Code Hennessy & Simmons IV LP, CHS Associates IV and certain other stockholders of the Issuer (the “Other Stockholders”), this reporting person may be deemed to be a member of a “group” within the meaning of Section 13(d)(3) of the Act and therefore may be deemed to beneficially own 643,991 shares of common stock of the Issuer, $0.01 par value per share (the “Common Stock”), beneficially owned by the Other Stockholders as of the date of this Statement (the “Other Stockholder Shares”). This reporting person expressly disclaims being a member of a Section 13D “group” with the Other Stockholders and expressly disclaims beneficial ownership of the Other Stockholder Shares. As a result, the Other Stockholder Shares have been excluded from lines 11 and 13 in the table above. If the Other Stockholder Shares were included in Lines 11 and 13 in the table above, these lines would identify this reporting person as beneficially holding, in the aggregate, 11,387,626 shares of Common Stock, or 57.8%.

(2) Based on 19,710,264 shares of Common Stock outstanding as of November 1, 2012, as disclosed in the Issuer’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2012, filed with the Securities and Exchange Commission (the “SEC”) on November 1, 2012 (the “Reported Shares Outstanding”).

EXPLANATORY NOTE

This Amendment No. 1 to Schedule 13D (“Amendment No. 1”) amends the statement on Schedule 13D relating to the shares of Common Stock of the Issuer filed by Code Hennessy & Simmons IV LP (“CHS IV”), CHS Management IV LP (“CHS Management”), CHS Capital LLC (“CHS LLC”) and CHS Associates IV (“CHS Associates” and together with CHS IV, CHS Management and CHS LLC, the “Reporting Persons”) with the SEC on June 14, 2012 (the “Original Statement”).

Due to the Stockholders Agreement, each of the Reporting Persons may be deemed to be a member of a “group” within the meaning of Section 13(d)(3) of the Act and therefore may be deemed to beneficially own the Other Stockholder Shares. Each of the Reporting Persons expressly disclaims being a member of a Section 13D “group” with the Other Stockholders and expressly disclaims beneficial ownership of the Other Stockholder Shares.

This Amendment No. 1 is being filed in order to report a decrease in the aggregate number of shares of Common Stock and in the aggregate percentage of the outstanding Common Stock that may be deemed to be beneficially owned by the Reporting Persons principally as a result of (i) the addition of the Issuer’s new chief financial officer as a party to the Stockholders Agreement and a holder of Other Stockholder Shares and (ii) the release and removal of the Issuer’s former chief financial officer as a party to the Stockholders Agreement and a holder of Other Stockholder Shares. Capitalized terms used herein but not defined herein have the meanings ascribed to them in Original Statement. Except as otherwise provided herein, each Item of the Original Statement remains unchanged. The Original Statement, as amended by this Amendment No. 1, is referred to collectively as this “Statement.”

The Reporting Persons do not affirm the existence of a group and are filing this Statement jointly pursuant to Rule 13d-1(k) under the Act.

Item 3. Source and Amount of Funds or Other Consideration.

The third paragraph of Item 3 of the Original Statement is hereby amended and restated in its entirety to read as follows:

The Issuer, CHS IV and CHS Associates entered into the Stockholders Agreement with the Other Stockholders, who are the beneficial owners of an aggregate of 643,991 shares of Common Stock as of the date of this Statement. Each of the Reporting Persons may be deemed to have acquired beneficial ownership of such shares. However, each of the Reporting Persons expressly disclaims any beneficial ownership of such shares.

Item 5. Interest in Securities of the Issuer.

Paragraphs (a) and (b) of Item 5 of the Original Statement are hereby amended and restated in their entirety to read as follows:

(a) - (b) As of the date of this Statement, CHS IV is the record owner of 10,726,003 shares of Common Stock. The shares of Common Stock owned by CHS IV may be deemed to be beneficially owned by CHS Management, which is the general partner of CHS IV, and by

CUSIP No. 36191X 100

13D

Page 11 of 15

CHS LLC, which is the general partner of CHS Management. CHS Management and CHS LLC disclaim beneficial ownership of the shares of Common Stock owned by CHS IV, except to the extent of a pecuniary interest therein. As of the date of this Statement, CHS Associates is the record owner of 17,632 shares of Common Stock. The shares of Common Stock owned by CHS Associates may be deemed to be beneficially owned by CHS LLC, which is the managing general partner of CHS Associates. CHS LLC disclaims beneficial ownership of the shares of Common Stock owned by CHS Associates, except to the extent of a pecuniary interest therein.

The 10,743,635 shares of Common Stock collectively owned by CHS IV and CHS Associates constitute approximately 54.5% of the outstanding shares of Common Stock, based on the Reported Shares Outstanding.

The Investment Committee of CHS LLC exercises sole voting and dispositive powers with respect to the shares of Common Stock held by CHS IV and CHS Associates. The members of the Investment Committee are Brian P. Simmons, Daniel J. Hennessy, Thomas J. Formolo, David O. Hawkins and Richard A. Lobo (collectively, the “Investment Committee Members”). Each of the Investment Committee Members disclaims beneficial ownership of the shares held by CHS IV and CHS Associates, except to the extent of a pecuniary interest therein.

The aggregate shares of Common Stock described above does not include shares of Common Stock beneficially owned by any other member of any “group” within the meaning of Section 13(d)(3) of the Act in which CHS IV, CHS Associates or any of the other Reporting Persons may be deemed a member.

Due to the relationship between the Reporting Persons and the Other Stockholders as set forth in the Stockholders Agreement, the Reporting Persons may be deemed to constitute a “group,” within the meaning of Section 13(d)(3) of the Act, with the Other Stockholders, and each of the Reporting Persons may be deemed to have shared voting and dispositive power with respect to the limited matters described in the Stockholders Agreement over (and therefore to beneficially own) the 643,991 shares of Common Stock beneficially owned in the aggregate by the Other Stockholders as of the date of this Statement, such that each Reporting Person may be deemed to beneficially own 11,387,626 shares of Common Stock, representing approximately 57.8% of the outstanding shares of Common Stock, based on the Reported Shares Outstanding. The Reporting Persons hereby expressly disclaim membership in any “group” with any person and expressly disclaim beneficial ownership of any shares of Common Stock that may be or are beneficially owned by the Other Stockholders. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that the Reporting Persons or any of their respective affiliates are the beneficial owners of any shares of Common Stock beneficially owned by the Other Stockholders for purposes of Section 13(d) of the Act or for any other purpose.

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

Item 6 of the Original Statement is hereby amended and restated in its entirety to read as follows:
