We have been instructed by our client, Huntsman Corporation ("Huntsman"), and have been requested by Huntsman to write this letter. We have not been involved in the preparation or negotiation of the Indenture or of the Guarantee and our role has been limited to the writing of this letter. This letter may be relied upon only by Huntsman and the Guarantor and may be used only in connection with the Indenture. This opinion may, however, be relied upon by Huntsman ICI Chemicals LLC 2 23rd November, 1999 Skadden, Arps, Slate, Meagher & Flom LLP solely for the purpose of rendering an opinion letter to the Company and the Guarantor in connection with the issuance and delivery of the Exchange Notes. 4.

(ii) The Microfiche and those searches did not fail to disclose any information relevant for the purposes of this opinion. (F) (i) The minutes referred to in sub-paragraph 5(B)(ii) truly record the proceedings of a duly convened, constituted and conducted meeting of the Board of Directors of the Guarantor. (ii) The resolutions passed and authorisations given at that meeting have not subsequently been amended, revoked or superseded. (G) (i) The written resolution referred to in sub-paragraph 5(B)(iii) was signed by a duly authorised representative of each member who would have been entitled to vote upon it if it had been proposed at a general meeting at which that member was present.

(H) (i) Each of the Guarantee and the Indenture is entered into by the Guarantor in good faith and in furtherance of its objects under its Memorandum of Association. (ii) Each of the Guarantee and the Indenture is in the best interests and to the advantage of the Guarantor. (I) Each of the Indenture and the Guarantee has the same meaning and effect as it would have if it were governed by English law. (J) As at 29th June, 1999, the giving of the Guarantee did not cause the Guarantor or its directors to be in default under article 16 (Borrowing Powers) of the Guarantor's Articles of Association. (K) (i) The Guarantor has not made any proposal for a voluntary arrangement under Part I of the Insolvency Act 1986 or passed any voluntary winding-up resolution.

(iv) The Statutory Declaration and the auditor's report which is required to be annexed to it was delivered to the Registrar of Companies, together with the written resolution referred to in paragraph 5(C)(iii) within the time limit and otherwise in accordance with section 156(5) of the Act. (M) All copy or draft documents examined by us conform to the originals. Opinion 7. We are of the opinion that: (A) The Guarantor is an unlimited liability company which has been duly incorporated and is validly existing.

(C) The signature and delivery of the Transaction Documents by the Guarantor and the performance of any obligations which it may have under the Transaction Documents have been authorised by all necessary corporate action on the part of the Guarantor. Huntsman ICI Chemicals LLC 5 23rd November, 1999 (D) The signature and delivery of the Transaction Documents by the Guarantor and the performance of any obligations which it may have under the Transaction Documents are not prohibited by any law or regulation applicable to English companies generally or by the Memorandum and Articles of Association of the Guarantor. (E) The choice of the laws of the State of New York ("New York law") as the governing law of the Indenture and of the Guarantee is a valid choice of law. English law will treat the validity and binding nature of the obligations contained in the Indenture and in the Guarantee as being governed by New York law. Reservations 8. Our opinion is qualified by the following reservations and any matter of fact not disclosed to us: (A) Laws relating to liquidation or administration or other laws or procedures affecting generally the enforcement of creditors' rights may affect any obligations of the Guarantor under the Transaction Documents and the remedies available. (B) We have not reviewed, and we express no opinion on the impact on our opinion of, the provisions of the Trust Indenture Act of 1939 of the United States of America (15 U.S. Code SS77aaa-77bbbb) (as amended) which are incorporated by reference into the Indenture or the Guarantee. (C) If an English court assumes jurisdiction: (i) It will not apply New York law if: (a) it is not pleaded and proved; or (b) to do so would be contrary to English public policy of mandatory rules of English law. (ii) It might have to have regard to the law of the place of performance of any obligation under the Indenture or under the Guarantee which is to be performed outside England and Wales. It may refer to that law in relation to the manner of performance and the steps to be taken in the event of defective performance. 9.
