A form of proxy has been included with this Notice.

NOTES:

IF YOU HAVE EXECUTED A STANDING PROXY, YOUR STANDING PROXY WILL BE VOTED AS INDICATED IN NOTE 2 BELOW, UNLESS YOU ATTEND THE EGM IN PERSON OR SEND IN A SPECIFIC PROXY.

A proxy need not be a shareholder of the Company. A shareholder entitled to attend and vote at the EGM is entitled to appoint one or more proxies to attend and vote in his/her stead. Please insert the name of the person(s) of your own choice that you wish to be appointed proxy in the space provided, failing which the Chairperson will be appointed as your proxy.

2	Any standing proxy previously deposited by a shareholder with the Company will be voted in favor of the resolutions to be proposed at the EGM unless revoked prior to the EGM or the shareholder attends the EGM in person or executes a specific proxy.

A form of proxy for use at the EGM is enclosed. Whether or not you propose to attend the EGM in person, you are strongly advised to complete and sign the enclosed form of proxy in accordance with the instructions printed on it and then deposit it (together with any power of attorney or other authority under which it is signed or a notarially certified copy of that power or authority) at Office Unit B8, 27/F, NCB Innovation Centre, No. 888 Lai Chi Kok Road, Kowloon, Hong Kong or send copies of the foregoing by email to ir@ms100.com.hk, in each case marked for the attention of Ming Shing Group Holdings Limited, not later than 48 hours before the time for the holding of the EGM or adjourned EGM in accordance with the existing Third Amended and Restated Articles of Association of the Company. Returning the completed form of proxy will not preclude you from attending the EGM and voting in person if you so wish.

If two or more persons are jointly registered as holders of a share, the vote of the senior person who tenders a vote, whether in person or by proxy, shall be accepted to the exclusion of the votes of other joint holders. For this purpose seniority shall be determined by the order in which the names stand on the Company’s register of members in respect of the relevant shares.

A shareholder holding more than one share entitled to attend and vote at the EGM need not cast the votes in respect of such shares in the same way on any resolution and therefore may vote a share or some or all such shares either for or against a resolution and/or abstain from voting a share or some or all of the shares and, subject to the terms of the instrument appointing any proxy, a proxy appointed under one or more instruments may vote a share or some or all of the shares in respect of which he is appointed either for or against a resolution and/or abstain from voting.

6	The quorum for the EGM is one or more holders of not less than one-third of the outstanding shares which carry the right to vote at the EGM.

7	“Ordinary Resolution” means a resolution passed by a simple majority of the votes cast by the shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at a general meeting, and includes a unanimous written resolution.

“Special Resolution” means a resolution passed by a majority of at least two-thirds of the votes cast by the shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at a general meeting of which notice specifying the intention to propose the resolution as a special resolution has been duly given, and includes a unanimous written resolution.

9	If the proxy is returned without an indication as to how the proxy shall vote, the proxy will vote in favor of or against the resolutions or may abstain at his/her discretion.

10	This form of proxy is for use by shareholders only. If the appointor is a corporate entity this form of proxy must either be under its seal or under the hand of some officer or attorney duly authorized for that purpose.

11	Any alterations made to this form must be initialed by you.

12	Voting will be conducted on a poll.
