3.4    The Collateral Agreement is hereby amended by deleting the “Preliminary Statement” thereof in its entirety and substituting the following in lieu thereof:
“The Grantors, the Trustee and the Noteholder Collateral Agent have entered into that certain Indenture dated as of August 31, 2010 (as it may be amended, restated, supplemented or modified from time to time, the “2010 Indenture”) pursuant to which the Issuer issued 9.5% Convertible Secured Notes due 2015 (the “2010 Notes”). Each Grantor entered into this Agreement in order to induce the purchase of the 2010 Notes by the Holders and to secure the following (the “2010 Secured Obligations”): (i) in the case of the Issuer, the Obligations under the 2010 Indenture and (ii) in the case of the Grantors (other than the Issuer), the Obligations that the Grantors agreed to guarantee pursuant to Article Thirteen of the 2010 Indenture.

As of March 22, 2013 (the “Refinancing Date”), the Grantors, the Trustee and the Noteholder Collateral Agent are entering into that certain Indenture dated as of the Refinancing Date (as it may be amended, restated, supplemented or modified from time to 

5

time, the “2013 Indenture”) pursuant to which the Issuer is issuing 9.5% Senior Secured Notes due 2015 (the “2013 Notes”). The 2013 Notes are being issued in exchange for not less than 82.5% in aggregate principal amount of the 2010 Notes, and, in connection with such exchange, from and after the Refinancing Date, all collateral that secures the 2010 Notes will thereafter secure the 2013 Notes in lieu of the 2010 Notes, as more particularly described in that certain First Amendment to Intercreditor Agreement, dated as of the Refinancing Date, which amends the Intercreditor Agreement. Each Grantor agrees that, from and after the Refinancing Date, this Agreement does not secure the 2010 Secured Obligations, and instead secures the following (the “Secured Obligations”): (i) in the case of the Issuer, the Obligations under the 2013 Notes and the 2013 Indenture and (ii) in the case of the Grantors (other than the Issuer), the Obligations that the Grantors agreed to guarantee pursuant to Article Thirteen of the 2013 Indenture. From and after the Refinancing Date, where appropriate in the context, all references in this Agreement (including in the preamble of this Agreement) to the “Indenture” shall refer to the 2013 Indenture, and all references in this Agreement to the “Notes” shall refer to the 2013 Notes.”

3.5    The Loan Parties will execute and deliver to the Notes Representative such documents as shall be necessary to further evidence or implement the amendments described in Section 3.2.
SECTION 4
EFFECTIVENESS
4.1    Sections 1.2, 1.3, 2, 3, 5.3 and 5.4 of this Amendment shall become effective immediately upon the effectiveness of the Exchange Offer (the “Amendment Effective Time”).
SECTION 5
MISCELLANEOUS
5.1    This Amendment may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this Amendment by telecopy or electronic transmission shall be effective as delivery of a manually executed counterpart of this Amendment.
5.2    This Amendment shall be construed in accordance with and governed by the law of the State of New York, except as otherwise required by mandatory provisions of law and except to the extent that remedies provided by the laws of any jurisdiction other than the State of New York are governed by the laws of such jurisdiction.
5.3    All references in the Intercreditor Agreement to “this Agreement”, “hereof”, “herein”, and similar terms shall mean and refer to the Intercreditor Agreement, as amended and modified by this Amendment, and all references in other Loan Documents to “the Intercreditor Agreement” shall mean such agreement as amended and modified by this Amendment.  This Amendment shall be deemed to be a Loan Document.

6

5.4    The Intercreditor Agreement, as amended hereby, is hereby ratified and confirmed and, except as amended hereby, remains in full force and effect.
5.5    The ABL Representative hereby represents and warrants that it has obtained all necessary consents of the ABL Secured Parties to this Amendment.
