Dear Registered Shareholder,

We are pleased to advise that the (i) 2014 Annual Report, (ii) 2014 Summary Financial Report and (iii) Circular containing Notice of 2015 Annual General Meeting and Proposed General Mandates to Issue and Buy Back Shares (the "Circular") of BOC Hong Kong (Holdings) Limited ("BOCHK") has been prepared in English and Chinese.

The Annual General Meeting of the Company will be held on Tuesday, 16 June 2015 at 2:00 p.m. at Four Seasons Grand Ballroom, Level 2, Four Seasons Hotel Hong Kong, 8 Finance Street, Central, Hong Kong.

Those Shareholders who (a) have received a printed copy of the 2014 Annual Report or the 2014 Summary Financial Report (as the case may be) in either the English or Chinese language only and would like to receive a printed copy in the other language; or (b) have chosen (or are deemed to have consented) to access the Corporate Communications (as defined below) posted on BOCHK's website in lieu of receiving printed copies (the "Website Option") and would like to receive a printed copy now; or (c) wish to change their choice of language and means of receipt of all corporate communications issued or to be issued by BOCHK to Shareholders including but not limited to, summary financial reports (the "Financial Summary"), complete annual reports and accounts (the "Full Financial Report"), interim reports, notices of meetings, listing documents, circulars and proxy forms (collectively the "Corporate Communications") of BOCHK, please complete Part A and/or Part B of the Request Form overleaf and return it by post, using the mailing label at the bottom of the Request Form (no postage stamp is necessary if posted in Hong Kong; otherwise please affix an appropriate stamp), or by hand delivery to BOCHK's share registrar, Computershare Hong Kong Investor Services Limited ("BOCHK's Registrar") at 17M Floor, Hopewell Centre, 183 Queen's Road East, Wan Chai, Hong Kong. You may also send a scanned copy of the Request Form duly completed and signed to BOCHK's Registrar via email to bochk.ecom@computershare.com.hk. The Request Form may also be downloaded from BOCHK's website at www.bochk.com or HKEx's website at www.hkexnews.hk.
You are entitled at any time by reasonable notice in writing to BOCHK's Registrar to change your choice of language and means of receiving Corporate Communications. Further, if you have chosen (or are deemed to have consented) to access the Corporate Communications posted on BOCHK's website and have any difficulty in receiving or gaining access to the relevant documents, for any reason, BOCHK's Registrar will promptly upon your notice send the printed form of the same to you free of charge. The aforesaid notice should contain your name, address, contact telephone number and relevant request and be sent to BOCHK's Registrar at the address as mentioned above or via email to bochk.ecom@computershare.com.hk.
Please note that printed English and Chinese versions of Corporate Communications of BOCHK are and will be available from BOCHK or BOCHK's Registrar upon request, and both language versions are or will be available on BOCHK's website at www.bochk.com and HKEx's website at www.hkexnews.hk.
You are encouraged to access the Corporate Communications posted on BOCHK's website in lieu of receiving printed copies, which helps to reduce the impact on the environment and, we believe, is a more convenient and prompt method of communication with shareholders.
If you have any queries relating to this letter, please do not hesitate to call BOCHK's enquiry hotline at (852) 2846 2700 during business hours from 9:00 a.m. to
