Dear Sirs

Form F-4 Registration Statement for AMEC plc

We have acted as UK tax law advisers to AMEC plc (the “Company”) in connection with the Registration Statement on Form F-4 (as amended or supplemented through the date of this letter, the “Registration Statement”), filed with the United States Securities and Exchange Commission, under the Securities Act of 1933 (the “Securities Act”), for the registration of ordinary shares of the Company in connection with the offer (the “Offer”) by the Company, through AMEC International Investments BV, a company organised under the laws of the Netherlands and a wholly owned subsidiary of the Company, to acquire all of the issued and to be issued registered shares, par value CHF3.00 per share, of Foster Wheeler AG, as described in the Registration Statement.

On the basis of our consideration of such matters of fact and law as we consider are necessary or appropriate for the purposes of this letter, the statements of law and HM Revenue & Customs (“HMRC”) practice contained in the Registration Statement under the heading “Material Tax Consequences––UK Tax Considerations”, subject to the limitations and qualifications contained therein, (the “UK Tax Disclosure”) represent our opinion as to the material UK tax consequences of (i) acceptance of the Offer for holders of ordinary shares of Foster Wheeler and (ii) the receipt of dividends on and the disposal of ordinary shares of the Company.

Our opinion is limited to the UK tax matters specifically covered in the UK Tax Disclosure. Our opinion is based on law and HMRC practice as at the date of this letter, and we assume no responsibility to inform you of any change that may occur.

Neither this opinion nor its contents may be quoted or referred to in any document or used for any other purposes whatsoever without our prior written consent.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the Tender Offer Statement on Schedule TO filed by the Company and AMEC International Investments BV. In giving such consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act.

This letter is governed by, and is to be construed in accordance with, English law.

This communication is confidential and may be privileged or otherwise protected by work product immunity.
