• b) a non-renounceable pro-rata entitlement offer of fully paid ordinary shares (Shares), on the basis of 1 new Share for every 12 Shares held as at 7:00pm (AEST) on Friday, 12 September 2025 ( Record Date ) to eligible shareholders, at an issue price of $0.025 per Share, to raise approximately $2 million before costs ( Entitlement Offer ).

The Placement is managed by Wilsons Corporate Finance Limited (Wilsons Advisory) (ACN 057 547 323) and MST Financial Services Pty Ltd (ACN 617 475 180).

Based on the current capital structure (and assuming no convertible securities are exercised or converted prior to the Record Date), a total of an additional 79,241,681 Shares will be issued if the Entitlement Offer is fully subscribed.

  • i. the provisions of Chapter 2M of the Corporations Act as they apply to the Company; and

  • ii. sections 674 and 674A of the Corporations Act;

• d) as at the date of this notice, there is no excluded information of the type referred to in sections 708AA(8) and 708AA(9) of the Corporations Act; and

• e) the potential effect that the issue of the new Shares pursuant to the Entitlement Offer will have on the control of the Company, and the consequences of that effect, will depend on a number of factors, including investor demand. If all shareholders subscribe for their entitlements, then all shareholders will retain their percentage ownership in the Company, and the issue of Shares under the Entitlement Offer is not expected to have any material effect on the control of the Company.

Given:

• i. the size and pricing of the Entitlement Offer;

• ii. the structure of the Entitlement Offer as a pro-rata issue; and

the issue of Shares under the Entitlement Offer is not expected to have any material effect or consequence on the control of the Company and it is not expected that any person will acquire voting power of 20% or more in the Company as a result of participating in the Entitlement Offer.

Further details of the Entitlement Offer are set out in the Investor Presentation released to ASX on Tuesday, 9 September 2025 and Entitlement Offer Booklet which is expected to be lodged with the ASX and dispatched on Tuesday, 16 September 2025.

Yours sincerely
