The Parties enter into this Addendum under the following terms and conditions:

SECTION ONE: RECITALS

1.1 On April 29, 2016, the Original Parties executed the Rights Subordination Agreement in order to regulate the exercise of certain collection rights held or that could be held by the Original Parties or their related entities against GSP (the “Agreement”). The initial-capitalized terms contained but not defined in this Addendum shall have the meaning ascribed to such terms in the Agreement.

1.2 On June 8, 2016, the Guarantors, the Administrative Agent and the Lenders executed the Waiver and Amendment Agreement (the “Waiver”), whereby they amended, among other things, the Standstill and Amendment Agreement and the Loan Agreement.

1.3 In compliance with the provisions of the Standstill and Amendment Agreement, as amended by the Waiver, CNO and OPIC has entered into on the date hereof a Trust Agreement with La Fiduciaria S.A., as trustee, and the Administrative Agent, with the participation of GyM and GSP (the “CNO-OPIC Trust Agreement”), in order to guarantee the obligations derived from the Corporate Guarantees furnished by OLPD and ODB.

SECTION TWO: PURPOSE

2.1 The Parties agree that, for all purposes of the Agreement, the CNO-OPIC Trust Agreement shall be considered as an Additional Guarantee. OPIC and CNO express their consent to such treatment.

2.2 CNO, OPIC and GyM become parties to the Agreement; express their agreement with the terms and conditions thereof; and agree to be fully bound by such terms and conditions in their capacity as grantors of the Additional Guarantees and potential creditors of GSP as a result of the enforcement of such Additional Guarantees (thus assuming, among other obligations established in the Agreement, the obligations set forth in Section Two of the Agreement). Without limiting the foregoing, and as established in subsection 2.6 of the Agreement, CNO, OPIC and GyM agree that, in the event that any of them fails to comply with the provisions of the Agreement and the Addendum, GSP shall be entitled to declare that the obligations referred to in the Agreement and the Addendum have been waived in accordance with Section 1295 of the Civil Code.

2.3 The Parties amend Section Two, subsection 2.5 of the Agreement in the following terms:

“The Guarantors that honor their payment obligations to the Lenders under the Guarantee Agreements in a partial or delayed manner, or as a result of the enforcement of Additional Guarantees, shall only be entitled to demand and receive from GSP the payment of up to the full amount of their credit rights against GSP, either directly or through other companies making up their economic group, provided that GSP honored in full the payments mentioned in subsection 2.4, items a) to c) above and there is no outstanding debt owed under the Credit Agreement or to long-term financial creditors.”
