Payment mechanisms for dividends
139 (A) Any dividend or other moneys payable in cash (whether in sterling or foreign currency pursuant to provision made under these Articles) on or in respect of a share may be paid by cheque or warrant sent through the post to the registered address (or in the case of an Approved Depositary, subject to the approval of the Directors, such persons and postal addresses as an Approved Depositary may direct) of the member or person entitled thereto (or, if two or more persons are registered as joint holders of the share or are entitled thereto in consequence of the death or bankruptcy of the holder, to any one of such persons) or to such person and such postal address as such member or person or persons may in writing direct. Every such cheque or warrant shall be made payable to, or to the order of, the person to whom it is sent or to such person as the holder or joint holders or person or persons entitled to the share in consequence of the death or bankruptcy of the holder may direct and payment of the cheque or warrant by the banker upon whom it is drawn shall be a good discharge to the Company. If any such cheque or warrant has or shall be alleged to have been lost, stolen or destroyed, the Directors may, on request of the person entitled thereto, issue a replacement cheque or warrant subject to compliance with such conditions as to evidence and indemnity and the payment of out of pocket expenses of the Company in connection with the request as the Directors may think fit. Every such cheque or warrant shall be sent at the risk of the person entitled to the money represented thereby. If on three consecutive occasions cheques or warrants in payment of dividends or other moneys payable on or in respect of any share have been sent through the post in accordance with the provisions of this Article 139 but have been returned undelivered or left uncashed during the periods for which the same are valid, the Company need not thereafter despatch further cheques or warrants in payment of dividends or other moneys payable on or in respect of the share in question until the member or other person entitled thereto shall have communicated with the Company and supplied in writing to the Transfer Office a postal address for the purpose.
(B) In respect of any share which is an uncertificated share, where the Company is authorised to do so by or on behalf of the holder or joint holders of that share in such manner as the Company shall from time to time consider sufficient, the Company may also pay any dividend or other moneys payable in cash (whether in sterling or foreign currency pursuant to provision made under these Articles) on or in respect of that share by means of the relevant system concerned (subject always to the facilities and requirements of that relevant system). Every such payment made by means of that relevant system shall be made in such manner as may be consistent with the facilities and requirements of the system. Without prejudice to the generality of the foregoing, such payment may include the sending by the Company or by any person on its behalf of an instruction to the Operator of the system to credit the cash memorandum account of the relevant holder or joint holders. The Company shall not be responsible for the loss of, or any loss resulting from, a payment made by means of a relevant system, and any such payment shall be at the sole risk of the holder or joint holders of the share or shares concerned.
(C) Where an Approved Depositary approved by the Directors for the purposes of this Article 139 has elected or agreed pursuant to provision made under these Articles to receive dividends in a foreign currency, the Directors may in their discretion approve the entering into of arrangements with such Approved Depositary to enable payment of the dividend to be made to such Approved Depositary in such foreign currency for value on the date on which the relevant dividend is paid, or such later date as the Directors may determine.
