Re:

James Hardie Industries SE

Ladies and Gentlemen:

          We have acted as special United States tax counsel to James Hardie Industries N.V., a public limited liability corporation registered in The Netherlands (the “Company”), in connection with the registration of 102,000,000 ordinary shares, par value €0.59 per share (the "Securities”), of James Hardie Industries SE (the “Issuer”) as a result of the transformation of the Company from a public limited liability corporation organized in The Netherlands (Naamloze Vennootschap (NV)) to a European Company (Societas Europaea (SE)) pursuant to the merger of a newly-formed subsidiary of the Company incorporated in Ireland with and into the Company. In that capacity, we previously rendered our opinion to the Company concerning material United States federal income tax consequences of the Proposal (as defined in the Prior Registration Statement, described below). At your request, we are rendering our opinion concerning material United States federal income tax consequences of Stage 2 of the Proposal (as defined in the Registration Statement, described below). At this time, Stage 1 has been implemented and the shareholder vote to approve the implementation of Stage 2 is pending. All capitalized terms used but not defined herein shall have the meaning ascribed to them in the Registration Statement.

          In the above capacity, we have reviewed (i) the registration statement on Form F-4 (File No. 333-160177) relating to the Securities filed by the Company on July 20, 2009 with the Securities and Exchange Commission under the Securities Act of 1933 (the “Prior

Registration Statement”), (ii) the registration statement on Form F-4 relating to the Securities filed by the Issuer on April 13, 2009 with the Securities and Exchange Commission under the Securities Act of 1933 (the “Registration Statement”) and (iii) such other documents as we have deemed necessary or appropriate in order to enable us to render the opinion below. We have relied upon statements and representations made by the Issuer (including in its capacity as the successor to the Company) and have assumed that such statements and representations are true without regard to any qualifications as to knowledge and belief.

          For purposes of our opinion, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, conformed, photostatic or electronic copies, and the authenticity of the originals of such latter documents. We have assumed that such documents, certificates, and records are duly authorized, valid, and enforceable. Where documents have been provided to us in draft form, we have assumed that the final executed versions of such documents will not differ materially from such drafts.

          In rendering our opinion, we have considered applicable provisions of the Internal Revenue Code of 1986, as amended, Treasury regulations promulgated thereunder, pertinent judicial authorities, published opinions and administrative pronouncements of the Internal Revenue Service and other applicable authorities, and income tax treaties to which the United States is a party, all as in effect and available on the date of the Registration Statement and all of which are subject to change or differing interpretations, possibly with retroactive effect. A change in any of the authorities upon which our advice is based could affect our conclusions herein. There can be no assurance, moreover, that our opinion will be accepted by the Internal Revenue Service or, if challenged, by a court.

          On the basis of the foregoing and subject to the limitations, qualifications, exceptions and assumptions set forth in the Registration Statement and herein, we are of the opinion that, although the description in the Registration Statement under the heading “Material Tax Considerations of the Proposal—US Federal Income Tax Consequences of Stage 2 of the Proposal” does not purport to describe all possible U.S. federal income tax consequences to US Holders of Stage 2 of the Proposal, under present U.S. federal income tax law, such description fairly summarizes, in all material respects, the U.S. federal income tax consequences of Stage 2 of the Proposal applicable to US Holders.

          Except as set forth herein, we express no opinions or views regarding the U.S. federal income tax consequences of the Proposal or any other transaction related to the Proposal.

          This opinion is expressed as of the date hereof, and we are not under any obligation to supplement or revise our opinion to reflect any legal developments or factual matters arising subsequent to the date hereof or the impact of any information, document, certificate, record, statement, representation, covenant, or assumption relied upon herein that

hereafter becomes incorrect or untrue. In addition, any changes to either the Registration Statement or the other documents referred to above could affect our conclusions herein.

          We hereby consent to the filing of this opinion with the Securities and Exchange Commission as an exhibit to the Registration Statement. We also consent to the reference to our firm under the caption “Legal Matters” in such Registration Statement. In giving this consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission.

Very truly yours,

/s/ Skadden, Arps, Slate, Meagher & Flom LLP
