Ladies and Gentlemen:

We have acted as special counsel to Huntsman International LLC, a Delaware limited liability company (the “Borrower”), in connection with that certain Amended Credit Agreement (as defined below) among the Borrower, the lenders from time to time party thereto and JPMorgan Chase Bank, N.A., as administrative agent (the “Administrative Agent”), and the other Opinion Documents (as defined below). Reference is made to that certain Credit Agreement dated as of August 16, 2005 (as amended by the Consent and First Amendment to Credit Agreement dated as of December 12, 2005, the Consent and Second Amendment to Credit Agreement and Amendment to Security Documents dated as of June 30, 2006, the Third Amendment to Credit Agreement dated as of April 19, 2007, the Fourth Amendment to Credit Agreement dated as of June 22, 2009, the Fifth Amendment to Credit Agreement dated as of March 9, 2010, the Sixth Amendment to the Credit Agreement dated as of March 7, 2011, the Seventh Amendment to Credit Agreement dated as of March 6, 2012 (the “Credit Agreement”) and as further amended by the Eighth Amendment to Credit Agreement dated as of March 11, 2013 (the “Eighth Amendment”) (with the Credit Agreement as amended by the Eighth Amendment, the “Amended Credit Agreement”) among the Borrower, the lenders from time to time party thereto and the Administrative Agent.

This letter is furnished pursuant to Section 3(iv) of the Eighth Amendment. Capitalized terms defined in the Amended Credit Agreement, used herein and not otherwise defined herein, shall have the meanings given them in the Amended Credit Agreement. As used in this letter, “Credit Parties” means the parties listed on Schedule B hereto.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter, except where a specified fact confirmation procedure is stated to have been performed (in which case we have with your consent performed the stated procedure). We have examined, among other things, the following:

(a) the Eighth Amendment;

(b) the Amended Credit Agreement;

(c) the Consent and Reaffirmation dated as of March 11, 2013 among the Borrower, each Subsidiary Guarantor party thereto and the Administrative Agent (the “Reaffirmation Agreement”);

(d) the Collateral Security Agreement dated as of August 16, 2005 by and among the Borrower, certain subsidiaries of the Borrower from time to time party thereto and JPMorgan Chase Bank, N.A., as the collateral agent (the “Collateral Agent”), as supplemented by Supplement No. 1 to Collateral Security Agreement dated as of December 20, 2005 and Supplement No. 2 to Collateral Security Agreement dated as of December 22, 2010 (the “Security Agreement”);

(e) copies of the following documents (the “Governing Documents”) (i) the Certificates of Formation and Operating Agreements listed on Exhibit A hereto for each of the entities specified therein (collectively, the “Delaware LLC Loan Parties); (ii) the Certificate of Incorporation and Bylaws listed on Exhibit A hereto for the entity specified therein (the “Delaware Corporation Loan Party” and, together with the Delaware LLC Loan Parties, the “Delaware Loan Parties”); and (iii) the Certificates of Formation and Operating Agreements listed on Exhibit B hereto for each of the entities specified therein (collectively, the “Texas Loan

Parties” and, together the Delaware Loan Parties, the “Opinion Parties”) (the documents described in clauses (i) through (iii) of this paragraph, the “Governing Documents”);

(f) photocopies of acknowledgement copies of the UCC-1 financing statements naming each of the Delaware Loan Parties as debtors and the Collateral Agent as secured party, together with all schedules and exhibits to such financing statement(s), as filed in the Office of the Secretary of State of the State of Delaware (the “Delaware Filing Office”), copies of which are attached hereto as Exhibit C (collectively, the “Delaware Financing Statements”); and

(g) photocopies of acknowledgement copies of the UCC-1 financing statements naming each of the Texas Loan Parties as debtors and the Collateral Agent as secured party, together with all schedules and exhibits to such financing statement(s), as filed in the Office of the Secretary of State of Texas, (the “Texas Filing Office”), a copy of which is attached hereto as Exhibit D (collectively, the “Texas Financing Statements”).

The documents described in subsections (a) - (c) above are referred to herein collectively as the “Opinion Documents.” The documents described in subsections (a) — (d) above are referred to herein collectively as the “Loan Documents.” As used in this letter, the “New York UCC” shall mean the Uniform Commercial Code as now in effect in the State of New York. As used in this letter, “Applicable UCC” shall mean the New York UCC, the Uniform Commercial Code as now in effect in the State of Texas (the “Texas UCC”) and/or the Delaware UCC (as defined below), as applicable.

Except as otherwise stated herein, as to factual matters we have, with your consent, relied upon the foregoing, and upon oral and written statements and representations of officers and other representatives of the Credit Parties and others, including the representations and warranties of the Credit Parties in the Loan Documents. We have not independently verified such factual matters.

We are opining as to the effect on the subject transaction only of the federal laws of the United States, the internal laws of the State of New York, and in paragraphs 1 and 5 of this letter, the Delaware General Corporation Law (the “DGCL”) and the Delaware Limited Liability Company Act (the “DLLCA”), and in paragraphs 2 and 5 of this letter, the Texas Business Organizations Code (the “TBOC”) and in paragraph 7 of this letter, the Delaware UCC (as defined below), and in paragraph 8 of this letter, the Texas UCC, and we express no opinion with respect to the applicability to the opinions expressed herein, or the effect thereon, of the laws of any other jurisdiction or, in the case of Delaware, any other laws, or in the case of Texas, any other laws, or as to any matters of municipal law or the laws of any local agencies within any state. With your permission, we have based our opinions set forth in paragraph 7 exclusively upon our review of Article 9 of the Uniform Commercial Code of the State of Delaware as set forth in the CCH Secured Transactions Guide without regard to judicial interpretations thereof or any regulations promulgated thereunder or any other laws of the State of Delaware (the “Delaware UCC”).

Except as otherwise stated herein, our opinions herein are based upon our consideration of only those statutes, rules and regulations which, in our experience, are normally applicable to borrowers and guarantors in secured loan transactions. We express no opinion as to any state or federal laws or regulations applicable to the subject transactions because of the legal or regulatory status of any parties to the Loan Documents or the legal or regulatory status of any of their affiliates. We express no opinion with respect to those matters, and to the extent elements of those opinions are necessary to the conclusions expressed herein, we have, with your consent, assumed such matters.

Subject to the foregoing and the other matters set forth herein, as of the date hereof:

1. Each of the Delaware LLC Loan Parties is a limited liability company under the DLLCA with limited liability company power and authority to enter into the Opinion Documents and perform its obligations thereunder. The Delaware Corporation Loan Party is a corporation under the DGCL with corporate power and authority to enter into the Opinion Documents and perform its obligations thereunder. With your consent, based solely on

certificates from public officials, we confirm that each of the Delaware Loan Parties is validly existing and in good standing under the laws of the State of Delaware.

2. Each of the Texas Loan Parties is a limited liability company under the TBOC with limited liability company power and authority to enter into the Opinion Documents and perform its obligations thereunder. With your consent, based solely on certificates from public officials, we confirm that each of the Texas Loan Parties is validly existing and in good standing under the laws of the State of Texas.

3. The execution, delivery and performance of the Opinion Documents by each Opinion Party that is a party thereto has been duly authorized by all necessary corporate or limited liability company, as applicable, action of each Opinion Party that is a party thereto and have been duly executed and delivered by each of the Opinion Parties.

4. Each of the Opinion Documents constitutes a legally valid and binding obligation of each Credit Party that is a party thereto, enforceable against each Credit Party in accordance with its terms.

5. The execution and delivery of the Opinion Documents by each Opinion Party and the consummation by such Opinion Party of the transactions contemplated by the Opinion Documents do not on the date hereof:

(i) violate the provisions of the Governing Documents of such Opinion Party;

(ii) violate any federal or New York statute, rule, or regulation applicable to the such Opinion Party or the DGCL, DLLCA or TBOC, as applicable; or

(iii) require any consents, approvals, or authorizations to be obtained by such Opinion Party from, or any registrations, declarations or filings to be made by such Opinion Party with, any governmental authority under any federal or New York statute, rule or regulation applicable to such Opinion Party (including, without limitation, Regulations T, U or X of the Board of Governors of the Federal Reserve System, assuming such Opinion Party complies with the

provisions of the Opinion Documents relating to the use of proceeds) or the DGCL, DLLCA or TBOC, as applicable, on or prior to the date hereof that have not been obtained or made.

6. The Eighth Amendment does not, of itself, adversely affect the validity under the New York UCC of the security interest of Collateral Agent for the benefit of the Secured Parties (as defined in the Security Agreement) (the “Secured Party”) in that part of the collateral described in Section 1.1 of the Security Agreement in which the Credit Parties have rights in which a valid security interest may be created under Article 9 of the New York UCC (the “UCC Collateral”) and after giving effect to the Eighth Amendment, Secured Party’s security interest in the UCC Collateral will be a valid security interest under Article 9 of the New York UCC to the same extent that it was a valid security interest immediately before the effectiveness of the Eighth Amendment.

7. The Eighth Amendment does not, of itself, adversely affect perfection of Secured Party’s security interest under the Delaware UCC in that part of the UCC Collateral in which, immediately before the effectiveness of the Eighth Amendment, Secured Party had a perfected security interest solely by virtue of the filing of the Delaware Financing Statements in the Delaware Filing Office (the “Delaware Filing Collateral”) and after giving effect to the Eighth Amendment, Secured Party’s security interest in such Delaware Filing Collateral will be a perfected security interest under Article 9 of the Delaware UCC to the same extent that it was a perfected security interest immediately before the effectiveness of the Eighth Amendment.

8. The Eighth Amendment does not, of itself, adversely affect perfection of Secured Party’s security interest under the Texas UCC in that part of the UCC Collateral in which, immediately before the effectiveness of the Eighth Amendment, Secured Party had a perfected security interest solely by virtue of the filing of the Texas Financing Statements in the Texas Filing Office (the “Texas Filing Collateral”) and after giving effect to the Eighth Amendment, Secured Party’s security interest in such Texas Filing Collateral will be a perfected security interest under Article 9 of the Texas UCC to the same extent that it was a perfected security interest immediately before the effectiveness of the Eighth Amendment.

9. None of the Credit Parties is required to be registered as an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

Except as expressly set forth in paragraphs 6 through 8, we do not express any opinion with respect to the creation, validity, attachment, perfection or priority of any security interest or lien or the effectiveness of any sale or other conveyance or transfer of real or personal property. The opinions above do not include any opinions with respect to compliance with laws relating to permissible rates of interest.

Our opinions are subject to:

(a) the effects of bankruptcy, insolvency, reorganization, preference, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights or remedies of creditors, and the judicial application of foreign laws or governmental actions affecting creditors’ rights;

(b) the effects of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), concepts of materiality, reasonableness, good faith, fair dealing and the discretion of the court before which a proceeding is brought;

(c) the invalidity under certain circumstances under law or court decisions of provisions for the indemnification or exculpation of or contribution to a party with respect to a liability where such indemnification, exculpation or contribution is contrary to public policy; and

(d) we express no opinion with respect to (i) consents to, or restrictions upon, governing law, jurisdiction, venue, service of process, arbitration, remedies or judicial relief; (ii) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitation, trial by jury or at law, or other procedural rights; (iii) waivers of broadly or vaguely stated rights; (iv) covenants not to compete; (v) provisions for exclusivity, election

or cumulation of rights or remedies; (vi) provisions authorizing or validating conclusive or discretionary determinations; (vii) grants of setoff rights; (viii) provisions to the effect that a guarantor is liable as a primary obligor, and not as a surety and provisions purporting to waive modifications of any guaranteed obligation to the extent such modification constitutes a novation; (ix) provisions for the payment of attorneys’ fees where such payment is contrary to law or public policy; (x) proxies, powers and trusts; (xi) provisions prohibiting, restricting, or requiring consent to assignment or transfer of any right or property; (xii) provisions for liquidated damages, default interest, late charges, monetary penalties, prepayment or make-whole premiums or other economic remedies to the extent such provisions are deemed to constitute a penalty; (xiii) provisions permitting, upon acceleration of any indebtedness, collection of that portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon; (xiv) we express no opinion with respect to any “swap” (as such term is defined in the Commodity Exchange Act), including any guarantee thereof, by any Credit Party which is not an “eligible contract participant” (as such term is defned in the Commodity Exchange Act) and (xv) the severability, if invalid, of provisions to the foregoing effect.

We express no opinion or confirmation as to federal or state securities laws (except as set forth in paragraph 9 of this letter), tax laws, antitrust or trade regulation laws, insolvency or fraudulent transfer laws, antifraud laws, compliance with fiduciary duty requirements, pension or employee benefit laws, usury laws, environmental laws, margin regulations (except as set forth in paragraph 5(iii)), FINRA rules or stock exchange rules (without limiting other laws excluded by customary practice).

Without limiting the generality of the foregoing, the opinions expressed above are also subject to the following limitations, exceptions and assumptions:

(a) We have assumed that any conditions to the effectiveness of the Opinion Documents have been satisfied or waived and that any required lender consents to the Opinion Documents have been obtained;

(b) We have assumed that, immediately prior to giving effect to the Opinion Documents, the Credit Agreement and the Security Agreement were the legally valid, binding and enforceable obligations of the parties thereto;

(c) We have assumed that, since the original date of execution thereof, except as specifically set forth in the definition of Loan Documents, the definition of Credit Agreement or the definition of Security Agreement, no Loan Document has been amended, restated, modified, supplemented or terminated and that no rights pursuant thereto have been released, waived or modified either expressly or by any action or inaction of the parties thereto and that no party has defaulted on its obligations under the Loan Documents;

(d) We have assumed that since the original date of filing thereof, no Delaware Financing Statement or Texas Financing Statement has been amended, restated, modified, supplemented or terminated and that no rights pursuant thereto have been released, waived or modified either expressly or by any action or inaction of the parties thereto;

(e) With respect to our opinions in paragraphs 6, 7 and 8, we have assumed that none of Secured Party’s interest in the UCC Collateral has been released in connection with the consummation of the transactions contemplated by the Opinion Documents; and

(f) The effect of New York law and court decisions which provide that certain suretyship rights and defenses are available to a party that encumbers its property to secure the obligations of another.

The opinions set forth above are also subject to (i) the unenforceability of contractual provisions waiving or varying the rules listed in Section 9-602 of the New York UCC, (ii) the unenforceability under certain circumstances of contractual provisions respecting self-help or summary remedies without notice of or opportunity for hearing or correction, (iii) the effect of provisions of the New York UCC and other general legal principles that impose a duty to act in good faith and in a commercially reasonable manner, and (iv) the effect of Sections 9-406, 9-407, 9-408 and 9-409 of the New York UCC on any provision of any Loan Document that purports to prohibit, restrict, require consent for or otherwise condition the assignment of rights under such Loan Document.

We call to your attention that enforcement of a claim denominated in a foreign currency may be limited by requirements that the claim (or a judgment in respect of the claim) be converted into United States dollars, and we express no opinion as to the enforceability of any indemnity for losses associated with the exchange of the judgment currency into any other currency.

Our opinions in paragraph 6 above are limited to Article 9 of the New York UCC, our opinions in paragraph 7 above are limited to Article 9 of the Delaware UCC and our opinions in paragraph 8 above are limited to Article 9 of the Texas UCC and therefore those opinion paragraphs, among other things, do not address collateral of a type not subject to, or excluded from the coverage of, Article 9 of the Applicable UCC.

Additionally,

(i) We express no opinion with respect to the priority of any security interest or lien.

(ii) We express no opinion with respect to any agricultural lien or any collateral that consists of letter-of-credit rights, commercial tort claims, goods covered by a certificate of title, claims against any government or governmental agency, consumer goods, crops growing or to be grown, timber to be cut, goods which are or are to become fixtures, as-extracted collateral or cooperative interests.

(iii) We assume the descriptions of collateral contained in, or attached as schedules to, the Loan Documents and any financing statements accurately and sufficiently describe the collateral intended to be covered by the Loan Documents or such financing statements provided that we make no such assumption as to the sufficiency of any collateral described solely by a type of collateral defined in Article 9 of the Applicable UCC. Additionally, we express no opinion as to whether the phrases “all personal property” or “all assets” or similarly general phrases would be sufficient to create a valid security interest in the collateral or particular item or items of collateral; however, we note that pursuant to Section 9-504 of the Applicable UCC the phrases “all

assets” or “all personal property” can be a sufficient description of collateral for purposes of perfection by the filing of a financing statement.

(iv) We have assumed that each grantor of any security interest has, or with respect to after-acquired property will have, rights in the collateral granted by it or the power to transfer rights in such collateral, and that each such grantor has received value, and express no opinion as to the nature or extent of any grantor’s rights in any of the collateral and we note that with respect to any after-acquired property, the security interest will not attach until the applicable grantor acquires such rights or power.

(v) We call to your attention the fact that the perfection of a security interest in “proceeds” (as defined in the Applicable UCC) of collateral is governed and restricted by Section 9-315 of the Applicable UCC.

(vi) We have assumed that the exact legal name of each Opinion Party is as set forth in the copy of the organizational documents certified by the applicable Secretary of State, and we have also assumed the accuracy of the other factual information set forth on the Delaware Financing Statements and the Texas Financing Statements, as applicable.

(vii) Section 552 of the federal Bankruptcy Code limits the extent to which property acquired by a debtor after the commencement of a case under the federal Bankruptcy Code may be subject to a security interest arising from a security agreement entered into by the debtor before the commencement of such case.

(viii) We express no opinion with respect to any property subject to a statute, regulation or treaty of the United States whose requirements for a security interest’s obtaining priority over the rights of a lien creditor with respect to the property preempt Section 9-310(a) of the Applicable UCC.

(ix) We express no opinion with respect to any goods which are accessions to, or commingled or processed with, other goods to the extent that the security interest is limited by Section 9-335 or 9-336 of the Applicable UCC.

(x) We call to your attention that a security interest may not attach or become enforceable or be perfected as to contracts, licenses, permits, equity interests or other property which are not assignable under applicable law, or are subject to consent requirements or contractual or other prohibitions or restrictions on assignment, except to the extent that any such prohibitions, restrictions or consent requirements may be rendered ineffective to prevent the attachment of the security interest pursuant to Sections 9-406, 9-407, 9-408 or 9-409 of the Applicable UCC, as applicable, and we note that the extent of any security interest created in reliance on such UCC provisions may be limited. In addition, we call to your attention that your rights under the Loan Documents as secured parties may be subject to the provisions of the organizational and governing documents of any entity in which any equity interests (or other rights of equity holders or investors) are pledged and the provisions of the applicable laws under which any such entity is organized.

(xi) We express no opinion regarding any security interest in any copyrights, patents, trademarks, service marks or other intellectual property, or any license or sublicense thereof or the proceeds of any of the foregoing except to the extent Article 9 of the Applicable UCC may be applicable to the foregoing and, without limiting the generality of the foregoing, we express no opinion as to the effect of any federal laws relating to copyrights, patents, trademarks, service marks or other intellectual property on the opinions expressed herein. In addition, we call to your attention that any license or sublicense of copyrights, patents, trademarks or other intellectual property may not be assignable unless such license or sublicense affirmatively permits the creation, perfection and enforcement of a security interest therein.

(xii) We express no opinion as to the enforceability of any provision of any Loan Document purporting to agree to the classification or type of any property for purposes of the Applicable UCC.

(xiii) We express no opinion with respect to the security interest of the Collateral Agent for the benefit of any secured party except to the extent that the Collateral Agent has been duly appointed as agent for such persons.

With your consent, we have assumed (a) that the Loan Documents have been duly authorized, executed and delivered by the parties thereto other than the Opinion Documents by the Opinion Parties, (b) that the Loan Documents constitute legally valid and binding obligations of the parties thereto other than the Opinion Documents with respect the Credit Parties, enforceable against each of them in accordance with their respective terms, and (c) that the status of the Loan Documents as legally valid and binding obligations of the parties is not affected by any (i) breaches of, or defaults under, agreements or instruments, (ii) violations of statutes, rules, regulations or court or governmental orders, or (iii) failures to obtain required consents, approvals or authorizations from, or make required registrations, declarations or filings with, governmental authorities, provided that we make no such assumption to the extent we have opined as to such matters with respect to the Opinion Parties or Credit Parties herein.

This letter is furnished only to you and is solely for your benefit in connection with the transactions referenced in the first paragraph. This letter may not be relied upon by you for any other purpose, or furnished to, assigned to, quoted to or relied upon by any other person, firm or entity for any purpose, without our prior written consent, which may be granted or withheld in our discretion. At your request, we hereby consent to reliance hereon by any future assignee of your interest in the loans under the Amended Credit Agreement pursuant to an assignment that is made and consented to in accordance with the express provisions of Section 12.8 of the Amended Credit Agreement, on the condition and understanding that (i) this letter speaks only as of the date hereof, (ii) we have no responsibility or obligation to update this letter, to consider its applicability or correctness to other than its addressees, or to take into account changes in law, facts or any other developments of which we may later become aware, and (iii) any such reliance by a future assignee must be actual and reasonable under the circumstances existing at the time of assignment, including any changes in law, facts or any other developments known to or reasonably knowable by the assignee at such time.

Very truly yours,
