4.6each of the documents which are the subject of this opinion is valid and binding on each party under the law to which it is expressed to be subject where that is not English law and that words and phrases used in those documents have the same meaning and effect as they would if those documents were governed by English law.

6.Based on the documents referred to, and assumptions made, in paragraphs 3 and 4 above and subject to the qualifications in paragraph 7 below and to any matters not disclosed to us, we are of the following opinion:

6.2BATIF has corporate power to enter into and to perform its obligations under the Programme Documents and has taken all necessary corporate action to authorise its execution, delivery and performance of the Programme Documents.

6.4British American Tobacco has corporate power to enter into and to perform its obligations under the Programme Documents and has taken all necessary corporate action to authorise its execution, delivery and performance of the Programme Documents.

7.1It should be understood that we have not been responsible for investigating or verifying the accuracy of the facts, including statements of foreign law, or the reasonableness of any statements of opinion, contained in the Registration Statement or the Prospectus Supplement, or that no material facts have been omitted from them.

7.2We express no opinion as to compliance or otherwise with any financial limitations on borrowings or the giving of guarantees by BATIF contained in BATIF’s Articles of Association or any financial limitations on borrowings or the giving of guarantees by British American Tobacco contained in British American Tobacco’s Articles of Association.

7.3We express no opinion as to compliance or otherwise with the limitation on the maximum aggregate principal amount of the debt securities which have been authorised by the Issuer with respect to the Registration Statement.

7.5Our opinion that BATIF and British American Tobacco are existing is based on each of the Issuer Searches and the Issuer Winding-up Searches. It should be noted that the Issuer Searches and the Issuer Winding-up Searches are not capable of revealing conclusively whether or not a winding-up or administration petition or order has been presented or made, a receiver has been appointed, a company voluntary arrangement has been proposed or approved, a moratorium has been applied for or has come into force or any other insolvency proceeding has commenced.

7.6Any amount referred to in provisions of the Notes or any Programme Document which provide for the payment by a person of additional interest or amounts upon a breach, default or similar occurrence by that person, may not be recoverable if it amounts to a penalty under English law.

7.8A certificate, determination, notification, minute or opinion might be held by the English courts not to be conclusive if it could be shown to have an unreasonable or arbitrary basis or in the event of manifest error despite any provision in any document to the contrary.

7.9Any contractual provision that purports to maintain the validity of the remainder of such contract despite the invalidity, illegality or unenforceability of one or more of its provisions may not be effective - it depends on the nature of the illegality, invalidity or unenforceability in question.

7.12We express no opinion as to the effect of any sanctions or other similar restrictive measures in relation to any party to the Programme Documents or the Notes or any transaction contemplated thereby.

7.13Effect may be given to the overriding mandatory provisions of the law of the country where the obligations arising out of a contract have to be or have been performed, in so far as those provisions render the performance of the contract unlawful. In such circumstances, the relevant obligations may not be enforceable.

7.14The English courts may have regard to the law of the country in which performance takes place in relation to the manner of performance and the steps to be taken in the event of defective performance.

7.15The English courts may not be restricted from applying overriding provisions of English law and if there is a provision of New York law that is manifestly incompatible with English public policy, it is possible that the English courts may not apply it.

8.This opinion is given on the basis that there will be no amendment to or termination or replacement of the documents, authorisations, consents and opinions referred to in the Schedule to this opinion. This opinion is also given on the basis that we undertake no responsibility to notify any addressee of this opinion of any change in English law after the date of this opinion.
