Except as mentioned above, we have not examined any agreements, instruments, records or other documents, and have not made any enquiries or other investigations, whatsoever relating to or concerning either English Guarantor or any of the other parties to the New York Law Documents in connection with the giving of this opinion.

4. Assumptions

In considering the documents referred to above we have assumed:

4.1 the genuineness of all signatures and seals on the New York Law Documents and that any signature or execution pages on which any such signatures and/or seals appear physically formed part of complete and final versions of those documents at the time of signing and/or sealing;

4.2 the accuracy and completeness of all facts stated in any such documents and of all representations and warranties given by or in respect of any party to the New York Law Documents (except insofar as they relate to matters of law on which we expressly opine in this opinion letter);

4.3 the authenticity and completeness of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us in electronic form or as photocopies or facsimile transmitted copies or other copies of originals and the authenticity and completeness of the originals from which such copies were taken;

4.4 that Delphi Automotive LLP was carrying on business in accordance with the Partnership Agreement on the date of execution of the Indenture;

3

4.5 the lack of bad faith and the absence of fraud, coercion, duress or under influence on the part of any party to the New York Law Documents and/or its directors, employees, agents and advisers;

4.6 that the parties to the Partnership Agreement had the capacity and power to enter into the Partnership Agreement, that the Partnership Agreement was duly authorised by and duly executed and delivered by or on behalf of each of the parties to it in the form examined by us (and we have relied upon the certified copy of the Partnership Agreement referred to in Paragraph 3.2.1 above) and that the Partnership Agreement creates legal, valid, binding and enforceable obligations under the laws of Delaware by which it is expressed to be governed;

4.7 that the certificates of the Secretary of each English Guarantor referred to in Paragraphs 3.2 and 3.3 above are correct in all respects and do not fail to disclose any matters which had they been disclosed would be material in connection with the giving of the opinions contained in this opinion letter, and there have been no changes to the matters referred to in that certificate;

4.8 that the written resolutions adopted by Delphi Automotive LLP’s Board of Managers, referred to in Paragraph 3.2.3 above were duly passed in accordance with the notice, quorum, voting and other similar terms of the Partnership Agreement and that any provisions contained in any relevant law or regulation relating to the declaration of members’ interests were duly observed in relation to the resolutions referred to above and that no member of Delphi Automotive LLP acted in breach of his duty in voting on any of the resolutions or members consents;

4.9 that the written resolutions adopted by Delphi Holdfi UK Limited’s Board of Directors, referred to in Paragraph 3.3.3 above were duly passed in accordance with the notice, quorum, voting and other similar requirements of the Companies Act 2006 and the Constitutional Documents;

4.10 that each New York Law Document has, in fact, been delivered by or on behalf of each English Guarantor and no New York Law Document is subject to any escrow or similar arrangement;

4.11 that in entering into the New York Law Documents, each English Guarantor did so in good faith and for the purpose of carrying on their businesses and at the time that the New York Law Documents were entered into there were reasonable grounds for the members of each English Guarantor to believe that the transactions to which the New York Law Documents relate, and the execution and delivery by each English Guarantor of the New York Law Documents and the exercise of its rights and the performance of its obligations thereunder, would materially benefit each English Guarantor and be likely to promote its success for the benefit of its members as a whole;

4.12 that at the time the New York Law Documents were executed, neither English Guarantor had passed a voluntary winding-up resolution, that no petition had been presented to or order made by a court for the winding up or dissolution of either English Guarantor, that no application had been made to a court, and no order had been made by the court, for an administration order in respect of either English Guarantor, that no appointment of an administrator and no notice of an intention to appoint an administrator had been made out of court or been given or filed with the court in respect of either English Guarantor and that no receiver, trustee, administrator, provisional liquidator, administrative receiver or similar officer had been appointed in relation to either English Guarantor or any of its assets or revenues. However, we note that the New York Law Documents were entered into more than two months ago and typically any such appointments or actions would have been disclosed by the searches of the type described in paragraph 3.4 above had they been made two months thereafter and we can confirm that none of the same are disclosed by the Searches;

4

4.13 that the information disclosed in the Searches was correct and complete and remains correct and complete as at the date of this opinion letter. It should be noted, however, that the Searches may not reveal whether any of the matters referred to in paragraph 4.12 above have occurred;

4.14 that none of the parties is or will be seeking to achieve any purpose not apparent from the New York Law Documents which might render any of the New York Law Documents illegal, void or unenforceable;

4.15 that there are no provisions of the laws of any country or jurisdiction outside England which would have any implications for the opinions we express.

Our opinion is confined to, and given on the basis of, English law as applied by the English courts at the date of this opinion letter and we have made no investigation of the laws of any country or jurisdiction other than England (and, in particular, we have not made any investigation of the laws of New York) and we do not express or imply any opinion thereon. Furthermore we do not express any opinion on European Union law as it affects any jurisdiction other than England (and, for this purpose, we have assumed that all statutory instruments and/or regulations made in England in purported implementation of any directive have been duly made in accordance with that directive and are valid in all respects under English law). The opinions given in this opinion letter are strictly limited to the matters stated in Paragraph 5 below and do not extend to and are not to be read as extending by implication to any other matters in connection with the New York Law Documents. We express no opinion as to matters of fact.

This opinion letter and all non-contractual obligations arising out of or in connection with it shall be governed by and construed in accordance with English law as at the date of this opinion letter.
