Notes:

1. GENERAL

The Notice of Extraordinary General Meeting and the Capital Reduction Resolution should be read in conjunction with the Scheme Booklet of which the Notice of Extraordinary General Meeting forms part (“Scheme Booklet”).

In these Explanatory Notes, the Extraordinary General Meeting is referred to as the Meeting.

Unless otherwise defined, terms used in this notice have the same meaning as set out in the Scheme Booklet.

(i) Information on the Capital Reduction Resolution

The Capital Reduction Resolution is being put to Shareholders to obtain approval under section 256C of the Corporations Act to an equal capital reduction in the Company’s ordinary share capital under section 256B of the Corporations Act.

The Capital Reduction Resolution is being proposed in connection with the Scheme and is, as a result, conditional on the Scheme becoming Effective and the Implementation Conditions being satisfied. Accordingly, the Capital Reduction Resolution will not come into effect unless and until the Scheme becomes Effective in accordance with section 411(10) of the Corporations Act, and the Implementation Condition are satisfied.

The effect on the Company and its Shareholders if the Capital Reduction Resolution is passed, together with all other factors that are material to the making of a decision by Shareholders whether to approve the Capital Reduction Resolution, is set out in the Scheme Booklet.

If the Capital Reduction Resolution is passed by the requisite majority, it will take effect provided that the Scheme is approved by the Requisite Majority of Company Shareholders and the Court and all other conditions to the Scheme are satisfied or waived (where applicable).

The Board is of the view that the Capital Reduction, taking into account all matters relevant to the Reorganisation Proposal, is fair and reasonable to Shareholders as a whole and will not materially prejudice the Company's ability to pay its creditors.

2. CHAIRPERSON

Brett Robert Smith will act as chair of the Extraordinary General Meeting and if they are unable or unwilling to act, Lau Tung Ni is to act as chair of the Extraordinary General Meeting.

3. VOTING

The Board recommends that you vote in favour of the Capital Reduction Resolution.

4. MAJORITIES REQUIRED

For the Capital Reduction Resolution to be passed, it must be approved by at least 50% of the votes cast on the Capital Reduction Resolution.

The vote on the resolution set out in the Notice of Extraordinary General Meeting will be decided on a poll as determined by the Chairperson of the Meeting, subject to the requirements of the Corporations Act and the Company's Constitution.

On a resolution determined by a poll, each registered Shareholder participating in the Meeting, or present by proxy, representative or attorney has one vote for every fully paid ordinary share held.

5. PROXY AND VOTING INSTRUCTIONS

(i) Entitlement to vote

In accordance with Reg 7.11.37 of the Corporations Regulations 2001 (Cth), the Board has made a determination that the time for determining eligibility to vote at the Meeting is at 6:00 p.m. (Hong Kong/Perth time) on Tuesday, 4 August 2026. Only those Shareholders entered on the register at that time will be entitled to attend and vote at the Meeting. The remaining comments in these explanatory notes are addressed to Shareholders entitled to attend and vote at the Meeting.

If more than one joint Shareholder is present at the Meeting (whether personally, by proxy or by attorney or by representative) and tenders a vote, only the vote of the joint Shareholder whose name appears first on the register will be counted.

(ii) Participation in, and voting at, the Meeting in person

To vote in person, you must attend the Meeting (whether physically in Hong Kong or through the Online Platform).

To vote by proxy, please refer to the proxy instructions in the section immediately below.

Voting at the Meeting will occur by poll. Every Shareholder present in person, via the Online Platform or by proxy shall have one vote for every share held by that Shareholder.

Shareholders who are eligible and wish to attend and vote at the Meeting in person will be admitted and given a voting paper(s) at the point of entry to the Meeting, once they have disclosed their name and address.

The Extraordinary General Meeting Online Platform will be open to log in approximately 30 minutes prior to the commencement of the Meeting and can be accessed from any location with internet connection using a smart phone, tablet device or computer. Shareholders should allow ample time to check into the Extraordinary General Meeting Online Platform to complete the related procedures.

The Extraordinary General Meeting Online Platform permits a “split vote” on a resolution. In other words, a Shareholder casting his/her/its votes through the Extraordinary General Meeting Online Platform does not have to vote all of his/her/its Shares in the same way (“For” or “Against”). In the case of a proxy, he/she can vote such number of Shares in respect of which he/she has been appointed as a proxy. Votes cast through the Extraordinary General Meeting Online Platform are irrevocable once the voting session at the Meeting ends.

(iii) Proxy instructions

A form of proxy (the “Proxy Form”) is to be used by Shareholders if they wish to appoint a representative (a “proxy”) to vote in their place.

Shareholder may submit their proxy appointment electronically via https://www.eproxyappointment.com/DML_2026EGM. Proxy Forms (and the power of attorney or other authority, if any, under which the Proxy Form is signed) must be returned to the Company’s Hong Kong share registrar, Computershare Hong Kong Investor Services Limited of 17M Floor, Hopewell Centre, 183 Queen’s Road East, Wanchai, Hong Kong or via email to [email protected], by 10:30 a.m. (Hong Kong/Perth time) on Tuesday, 4 August 2026, being not later than 48 hours before the commencement of the Meeting. Any Proxy Form received after that time will not be valid for the Meeting.

(iv) Appointment of a proxy

A Shareholder entitled to attend and vote at the Meeting is entitled to appoint a proxy. The proxy may, but need not be, a Shareholder. Shareholders may submit their proxy appointment electronically. If more than one proxy is to be appointed, the printed proxy form, instead of electronic proxy appointment, must be used.

For printed proxy form, if you wish to appoint the Chairperson of the Meeting as your proxy, mark the box as indicated on the Proxy Form. If the person you wish to appoint as your proxy is someone other than the Chairperson of the Meeting, please write the name of that person. If you leave this section blank, or your named proxy does not attend the Meeting, the Chairperson will be your proxy.

If the Chairperson of the Meeting is appointed as your proxy, or is appointed by default, you acknowledge that the Chairperson may exercise your proxy even though he has an interest in the outcome of the resolution and that votes cast by him for the resolution, other than as proxy holder, would be disregarded because of that interest. If the Shareholder is entitled to cast two or more votes at the Meeting, the Shareholder may appoint not more than two proxies. Where the Shareholder appoints more than one proxy, the Shareholder may specify the proportion or number of votes each proxy is appointed to exercise. If such proportion or number of votes is not specified, each proxy may exercise half of the Shareholder’s votes.

(v) Corporate representatives

A body corporate that is a Shareholder, or that has been appointed as a proxy, is entitled to appoint a person to act as its representative at the Meeting. The appointment of the representative must comply with the requirements under section 250D of the Corporations Act. If a Shareholder appoints a body corporate as the Shareholder’s proxy to attend and vote for the Shareholder at the Meeting, the representative of the body corporate to attend the Meeting must produce the certificate of appointment of representative prior to admission to the Meeting. A form of the certificate may be obtained from the Company’s share registrar.

If a certificate is completed under power of attorney or other authority, the power of attorney or other authority, or a certified copy of the power of attorney or other authority, must accompany the completed certificate unless the power of attorney or other authority has previously been noted by the share registrar.

Body corporate representatives of Shareholders will be admitted to the meeting and given a voting paper(s) on providing at the point of entry to the Meeting, written evidence of their appointment, their name and address and the name of their appointors.

(vi) Proxies and conduct of Meeting

Sections 250BB and 250BC of the Corporations Act apply to voting by proxy and will apply to the conduct of the Meeting. Broadly, this means that:

(a) if proxy holders vote, they must cast all directed proxies as directed; and
(b) any directed proxies which are not voted will automatically default to the Chairperson, who must vote the proxies as directed.

Pursuant to section 250BB of the Corporations Act, an appointment of a proxy may specify the way the proxy is to vote on a particular resolution and, if it does:

(a) the proxy need not vote on a show of hands, but if the proxy does so, the proxy must vote that way (i.e. as directed); and
(b) if the proxy has two or more appointments that specify different ways to vote on the resolution — the proxy must not vote on a show of hands; and
(c) if the proxy is the Chairperson of the Meeting at which the resolution is voted on — the proxy must vote on a poll, and must vote that way (i.e. as directed); and
(d) if the proxy is not the Chairperson — the proxy need not vote on the poll, but if the proxy does so, the proxy must vote that way (i.e. as directed).

Under section 250BC of the Corporations Act, if:

(a) an appointment of a proxy specifies the way the proxy is to vote on a particular resolution at a meeting of a company’s members;
(b) the appointed proxy is not the Chairperson of the Meeting;
(c) at the meeting, a poll is duly demanded on the resolution; and

(d) either of the following applies:

(1) the proxy is not recorded as attending the meeting;
