(v) a favorable opinion, addressed to the Collateral Agent and each of the Secured Parties, in form and substance reasonably satisfactory to the Collateral Agent, from local counsel in the jurisdiction in which each Mortgaged Property is located substantially to the effect, without limitation, that: (A) each Mortgage Amendment is in proper form for recording in order for each Amended Mortgage to create, when each applicable Mortgage Amendment is recorded in the appropriate recording office, a mortgage lien on the applicable Mortgaged Property, and a security interest in that part of the Mortgaged Property constituting fixtures; (B) the recording of each Mortgage Amendment in the appropriate recording office is the only filing or recording necessary to give constructive notice to third parties of the lien created by such Amended Mortgage and the security interest in that part of the Mortgaged Property constituting fixtures created by such Amended Mortgage as security for the Secured Obligations (as defined in each of the existing Mortgages), including the Obligations evidenced by and as defined in the Credit Agreement, as amended pursuant to this First Amendment, and the other documents executed in connection therewith, for the benefit of the Secured Parties; (C) each Amended Mortgage, following its due execution and delivery by the Borrower or the applicable Loan Party, shall constitute a legal, valid and binding obligation of the Borrower or the applicable Loan Party, as the case may be, enforceable against the Borrower or the applicable Loan Party in accordance with its terms, and upon recording in the applicable recording office shall create a valid, perfected lien on the applicable Mortgaged Property covered thereby; and (D) no other documents, instruments, filings, recordings, re-recordings, re-filings or other actions, including, without limitation, the payment of any mortgage recording taxes or similar taxes, are necessary or appropriate under applicable law in order to maintain the continued enforceability, validity or priority of the liens created by the Amended Mortgage, as security for the Secured Obligations, including the Obligations evidenced by and as defined in the Credit Agreement, as amended pursuant to the First Amendment, and the other documents executed in connection therewith, for the benefit of the Secured Parties.

SECTION 7. Representations and Warranties. The Borrower and each of the other Loan Parties represent and warrant as follows as of the date hereof:

(a) The execution, delivery and performance by each Loan Party of this First Amendment are within such Loan Party’s corporate or other powers and have been duly authorized by all necessary corporate or other organizational action. Neither the execution, delivery and performance by each Loan Party of this First Amendment will (a) contravene the terms of such Person’s Organization Documents, (b) conflict with or result in any breach or contravention of, or the creation of any Lien upon any of the property or assets of the Borrower or any of the Restricted Subsidiaries (other than as permitted by Section 7.01 of the Credit Agreement), or require any payment under (i) any Contractual Obligation to which such Person is a party or affecting such Person or the properties of such Person or any of its Restricted Subsidiaries or (ii) any material order, injunction, writ or decree of any Governmental Authority or any arbitral award to which such Person or its property is subject; or (c) violate any applicable material Law, except to the extent that any such breach, contravention or payment (but not the creation of any Lien) referred to in clause (b)(i) could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(b) This First Amendment has been duly executed and delivered by each Loan Party that is a party to the Loan Documents and constitutes a legal, valid and binding obligation of each Loan Party that is a party hereto or thereto, enforceable against such Loan Party in accordance with its terms, except as such enforceability may be limited by Debtor Relief Laws and by general principles of equity.

(c) Upon the effectiveness of this First Amendment and (i) both before and immediately after giving effect to this First Amendment and the making of the Replacement Term Loans as contemplated herein and (ii) immediately before and after giving effect to the Incremental Term Loans and the use of proceeds thereof, no Default or Event of Default exists.

(d) Each of the representations and warranties of the Borrower and each other Loan Party contained in Article V of the Credit Agreement and each other Loan Document immediately before and after giving effect to each and all parts of this First Amendment is true and correct in all material respects on and as of the date hereof; provided that, to the extent that such representations and warranties specifically refer to an earlier date, they are true and correct in all material respects as of such earlier date.

SECTION 8. Reference to and Effect on the Credit Agreement and the Loan Documents.

(a) On and after the First Amendment Effective Date, (i) each reference in the Credit Agreement to “this Agreement,” “hereunder,” “hereof” or words of like import referring to the Credit Agreement shall mean and be a reference to the Credit Agreement, as amended by this First Amendment; (ii) the Incremental Term Loans shall constitute “Incremental Term Loans” and “Term Loans” as defined in the Credit Agreement; and (iii) the Incremental Term Lender shall constitute a “Lender” as defined in the Credit Agreement.

(b) The Credit Agreement and each of the other Loan Documents, as specifically amended by this First Amendment, are and shall continue to be in full force and effect and are hereby in all respects ratified and confirmed. Without limiting the generality of the foregoing, the Collateral Documents and all of the Collateral described therein do and shall continue to secure the payment of all Obligations of the Loan Parties under the Loan Documents, in each case, as amended by this First Amendment.

(c) The execution, delivery and effectiveness of this First Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of any Lender or the Administrative Agent under any of the Loan Documents, nor constitute a waiver of any provision of any of the Loan Documents. On and after the effectiveness of this First Amendment, this First Amendment shall for all purposes constitute a Loan Document.

SECTION 9. Specific Limitations Applicable to Singapore Subsidiaries and Hong Kong Subsidiaries. Notwithstanding anything to the contrary contained in this First Amendment, until such time as all required statutory whitewash processes under Section 76(10) of the Companies Act, Chapter 50 of Singapore (the “Whitewash Procedures”) have been completed, each Singapore Subsidiary and each Hong Kong Subsidiary executing this First Amendment as a Guarantor does so solely in respect, and to the extent only, of the replacement of the Refinanced Term Loans by the Replacement Term Loans strictly on the terms, and in accordance with the provisions, of the third full paragraph of Section 10.01 of the Credit Agreement and not also in respect of the making of the Incremental Term Loans, Incremental Upsize Amendment, the Incremental Term Loan Amount, Incremental Credit Extensions, Incremental Amendment, Incremental Term Loan Amendment or otherwise.

SECTION 10. Execution in Counterparts. This First Amendment may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery by facsimile or electronic transmission of an executed counterpart of a signature page to this First Amendment shall be effective as delivery of an original executed counterpart of this First Amendment.

SECTION 11. Governing Law. This First Amendment shall be governed by, and construed in accordance with, the law of the State of New York (without regard to conflict of laws principles).

Reference is made to (a) the Credit Agreement dated as of June 17, 2010 (as amended, supplemented or otherwise modified prior to the date hereof, the “Credit Agreement”), among STYRON S.À R.L., a limited liability company (societe a responsabilite limitee) organized under the laws of Luxembourg (the “Borrower”), the Guarantors party thereto from time to time, DEUTSCHE BANK AG NEW YORK BRANCH, as Administrative Agent and Collateral Agent, each lender from time to time party thereto (collectively, the “Lenders” and individually, a “Lender”) and DEUTSCHE BANK AG NEW YORK BRANCH, as L/C Issuer and Swing Line Lender and (b) First Amendment, dated as of February 2, 2011 (“First Amendment”), to the Credit Agreement attached as Exhibit A hereto. Capitalized terms used but not otherwise defined in this Guarantor Consent and Reaffirmation (this “Consent”) are used with the meanings attributed thereto in First Amendment.

Each Guarantor hereby consents to the execution, delivery and performance of the First Amendment, including the refinancing of the Refinanced Term Loans and the making of the Replacement Term Loans and the Incremental Term Loans contemplated thereby, and agrees that each reference to the Credit Agreement in the Loan Documents shall, on and after the First Amendment Effective Date, be deemed to be a reference to the Credit Agreement as amended by First Amendment.

Each Guarantor hereby acknowledges and agrees that, after giving effect to the First Amendment, all of its respective obligations and liabilities under the Loan Documents to which it is a party, as such obligations and liabilities have been amended by the First Amendment, are, subject to such Guarantors limitations in accordance with Article XI (Guarantee) of the Credit Agreement, reaffirmed, and remain in full force and effect.

After giving effect to the First Amendment, each Guarantor reaffirms each Lien granted by it to the Collateral Agent for the benefit of the Secured Parties under each of the Loan Documents to which it is a party, which Liens were always intended by the parties to secure the Obligations as amended from time to time (including any increases thereof) and shall continue in full force and effect during the term of the Credit Agreement as amended by the First Amendment, and shall continue to secure the Obligations (after giving effect to the First Amendment and including any increase of such Obligations), in each case, on and subject to the terms and conditions set forth in the Credit Agreement, as amended by the First Amendment, and the other Loan Documents.

Notwithstanding anything to the contrary set out in this Consent, until such time as all required statutory whitewash processes under Section 76(10) of the Companies Act, Chapter 50 of Singapore (the “Whitewash Procedures”) have been completed, each Singapore Subsidiary and each Hong Kong Subsidiary executing this Consent as a Guarantor hereby consents, acknowledges, agrees and reaffirms as to the aforesaid matters solely in respect, and to the extent only, of the replacement of the Refinanced Term Loans by the Replacement Term Loans strictly on the terms, and in accordance with the provisions, of the third full paragraph of Section 10.01 of the Credit Agreement and not also in respect of the making of the Incremental Term Loans, Incremental Upsize Amendment, the Incremental Term Loan Amount, Incremental Credit Extensions, Incremental Amendment, Incremental Term Loan Amendment or otherwise.

Nothing in this Consent shall create or otherwise give rise to any right to consent on the part of the Guarantors to the extent not required by the express terms of the Loan Documents.

This Consent is a Loan Document and shall be governed by, and construed and interpreted in accordance with, the law of the state of New York (without regard to conflict of laws principles).

This Consent may be executed in counterparts, and all such counterparts taken together shall be deemed to constitute one and the same instrument.

IN WITNESS WHEREOF, the parties hereto have duly executed this Consent as of the date first set forth above.
