To the Shareholders

Dear Sir of Madam,

PROPOSAL INVOLVING GENERAL MANDATES TO REPURCHASES SHARES AND TO ISSUE NEW SHARES OF THE COMPANY AT THE ANNUAL GENERAL MEETING

On 16th March 2005, the board of directors (the “Board”) of Unity Investments Holdings Limited (the “Company”) made the proposal involving general mandates to repurchase shares and to issue new shares of the Company (the “Proposal”).

The proxy form, among other things, dispatched to the shareholders (the “Shareholders”) of the Company on 29th March 2005 will need to be amended by the addition thereto of the resolution to grant a general mandate to the Directors to issue, allot and otherwise deal with the Company’s shares. In this regard, the Board is pleased to enclose the amended proxy form for your reference and use (as the case may be).

Shareholders who wish to appoint a proxy should use the amended form of proxy enclosed and return it to the share register of the Company, Tengis Limited at 28/F., BEA Harbour View Centre, 56 Gloucester Road, Wanchai, Hong Kong and in any event not less than 48 hours before the time appointed for the holding of the AGM or any adjournment thereof, whether or not they intend to be present at the AGM. The completion and return of the form of proxy will not preclude the Shares from attending and voting in person at the AGM or any adjournment thereof should they so wish.

Yours faithfully, By Order of the Board POON SUK CHING Company Secretary

Hong Kong, 1st April 2005
