2. Choice of language and means of receipt of corporate communications

The attached reply form asks whether, in the future, you wish to receive the Company's corporate communications(Note) in printed form or by electronic means through our website and, if in printed form, whether you wish to receive English language version only, Chinese language version only or both language versions. To minimise use of paper and to save printing and mailing costs, the Company recommends you to elect to receive corporate communications electronically on the Company's website. To make your choice, please complete the enclosed reply form and sign and return it to the Company's Registrars, Computershare Hong Kong Investor Services Limited using the provided prepaid mailing label or via e-mail to cosec@clp.com.hk or clp.ecom@computershare.com.hk.

If the Company does not receive a duly completed and signed reply form from you or receives no response from you indicating that you object to receiving corporate communications in electronic form on the Company's website on or before 29 September 2015, you are deemed to have consented to receive all our future corporate communications in electronic form on the Company's website instead of receiving them in printed form. In that event, when the Company makes a corporate communication, we will send you a notification that the corporate communication has been made available on the Company's website. The notification will be sent to you by e-mail (if you have provided an e-mail address) or (if you have not provided an e-mail address) by post to you at your address as it appears in the Company's Register of Shareholders maintained by the Company's Registrars.

You may change your choice of language (English and/or Chinese) and means of receipt (in printed form or through our website) of the Company's future corporate communications, free of charge, at any time by reasonable notice in writing (not less than 7 days) to the Company or the Company's Registrars or via e-mail (cosec@clp.com.hk or clp.ecom@computershare.com.hk), notwithstanding any wish to the contrary you have previously conveyed to the Company or the Company's Registrars. Even if you have chosen (or are deemed to have consented) to receive all future corporate communications by electronic means but for any reason you have difficulty in receiving or gaining access to the corporate communications, we will promptly, upon your request, send the corporate communications to you in printed form free of charge. Please note that printed copies of the English and Chinese versions of all future corporate communications will be available from the Company and the Company's Registrars on request.
