“[The Defendant] irrevocably appoints Law Debenture Corporate Services Limited…to receive, for it and on its behalf, service of process in any Proceedings in England. Such service shall be deemed completed on delivery to such process agent (whether or not it is forwarded to and received by the [Defendant]). If for any reason such process agent ceases to be able to act as such or no longer has an address in England, [the Defendant] irrevocably agrees to promptly appoint a substitute process agent acceptable to the Trustee and shall immediately notify the Trustee of such appointment. Nothing shall affect the right to serve process in any other manner permitted by law.”
