 such amendment (provided, however, that, for the purposes of our obligation to pay additional amounts as provided, and subject to the limitations as set forth, in the relevant indenture and as described under the section headed “Additional  
 Amounts” above, references to such successor entity’s country of organization will be added to the references to the UK);                                                                                                                        |

 the holders such additional amounts as provided by, and subject to the limitations set forth in, the relevant indenture and as described under the section headed “Additional Amounts” above (provided, however, that for these purposes such 
 successor entity’s country of organization will be substituted for the references to the UK); and                                                                                                                                             |

| • |     | immediately after giving effect to such assumption of obligations, no event of default or default and no event

Upon any such assumption, the successor entity will succeed to, and be substituted for, and may exercise all of our rights and powers under the relevant indenture with respect to the debt securities of such series with the same effect as if the successor entity had been named under the relevant indenture. 26
