If such appointment is not made as required, service can be effected, by posting the claim form, notice, order, judgment or other document by registered letter with acknowledgement of receipt or equivalent under the address of the respective Party stated in clause 8.1. Service shall then be deemed to have been effected on the addressee on the tenth (10th) day following the lodging of the letter. The Parties shall promptly after the Effective Date and upon the appointment of any new agent for service of process issue to the agent a written power of attorney and shall irrevocably instruct the agent to submit such deed in connection with any service of process under or in connection with this Agreement.
