EXPLANATORY MEMORANDUM TO NOTICE OF GENERAL MEETING

This Explanatory Memorandum accompanies and forms part of the Orbminco Limited (‘ Company ’) Notice of Meeting for a General Meeting to be held on 18 September 2025 via a webcast at 11:00 am (ACST).

This Explanatory Memorandum should be read in conjunction with, and forms part of, the accompanying Notice of Meeting. The purpose of this Explanatory Memorandum is to provide information to Shareholders in deciding whether or not to pass the Resolutions set out in the Notice.

Shareholders should read the Notice and this Explanatory Memorandum carefully before deciding how to vote on the Resolutions.

1. Resolution 1 - Ratification of Prior Issue of Placement Shares Issued under Listing Rule 7.1

Background

The Company received binding commitments from professional and sophisticated investors for the following share placements:

• (a) on 23 May 2025, a share placement of 880,000,000 ordinary shares to sophisticated and professional investors and three Directors (subject to shareholder approval) at an issue price of $0.001 to raise approximately $0.880m; and

• (b) on 27 June 2025, a further share placement of 205,000,000 ordinary shares to sophisticated and professional investors at an issue price of $0.001 to raise approximately $0.205m.

(together, the Share Placement ).

As a portion of the Share Placement, the Company issued a total of:

• (a) 300,000,000 Shares on 4 June 2025; and

• (b) 49,635,192 Shares on 27 June 2025,

utilising the Company’s existing placement capacity under Listing Rule 7.1.

Resolution 1 is seeking Shareholder ratification pursuant to Listing Rule 7.4 for the issue of the portion of the Placement Shares issued under Listing Rule 7.1 as detailed above.

Listing Rule 7.4

Listing Rule 7.1 provides that a company must not (subject to specified exceptions), without the approval of shareholders, issue or agree to issue during any 12 month period any Equity Securities, or other securities with rights to conversion to equity (such as an option), if the number of those securities exceeds 15% of the number of ordinary securities on issue at the commencement of that 12 month period.

Listing Rule 7.1A provides that an “eligible entity” may issue up to 10% of its issued share capital without shareholder approval in the 12 month period following its annual general meeting, provided that shareholder approval is obtained by special resolution to do so at the annual general meeting. This issuing capacity is in addition to the capacity under Listing Rule 7.1. An “eligible entity” under the Listing Rules is an entity that is not included in the S&P/ASX 300 index and has a market capitalisation of $300 million or less. The Company satisfied these criteria.

10948454v4

Listing Rule 7.4 provides that an issue of Equity Securities made without prior approval under Listing Rule 7.1 can be treated as having been made with approval if shareholders subsequently approve it and the issue did not breach Listing Rule 7.1. Issues made without shareholder approval in accordance with Listing Rule 7.1A can also be ratified under Listing Rule 7.4 and provided the issue did not breach Listing Rule 7.1A.

Information required by Listing Rule 14.1A

If Resolution 1 is passed, the portion of the Placement Shares detailed above will be excluded in calculating the Company’s 15% placement capacity in Listing Rule 7.1, effectively increasing the number of Equity Securities the Company can issue without Shareholder approval over the 12 month period following the issue date.

If Resolution 1 is not passed, the portion of the Placement Shares detailed above will be included in calculating the Company’s 15% placement capacity in Listing Rule 7.1, effectively decreasing the number of Equity Securities that the Company can issue without Shareholder approval over the 12 month period following the issue date.

Information required by Listing Rule 7.5

The following information is provided for the purposes of Listing Rule 7.5:

• (a) the following Placement Shares were issued utilising the Company’s 15% placement capacity under Listing Rule 7.1:

• (i) 300,000,000 Shares on 4 June 2025; and

• (ii) 49,635,192 Shares on 23 June 2025,

• (b) the issue price for the Shares was $0.001 per Share;

• (c) the Shares issued were fully paid ordinary shares in the capital of the Company issued on the same terms and conditions as the Company’s existing Shares;

• (d) the Placement Shares were issued to sophisticated and professional investors as defined by the Corporations Act, who were identified through a bookbuild process which involved the Company’s lead manager, Cerberus Advisory Pty Ltd, seeking expressions of interest to participate in the capital raising from non-related parties of the Company;

• (e) in accordance with paragraph 7.4 of ASX Guidance Note 21, the Company confirms that none of the recipients were:

• (i) related parties of the Company, members of the Company’s Key Management Personnel, substantial holders of the Company, advisers of the Company or an associate of any of these parties; and

• (ii) issued more than 1% of the issued capital of the Company, other than for Patron Partners Pty Ltd, Noble Investments Superannuation Fund Pty Ltd, Tornado Nominees Pty Ltd, Super Rocket Pty Ltd and RVS Holdings Pty Ltd;

• (f) the funds raised from this issue will be used to fund exploration at the Majestic North Project and working capital; and

• (g) a voting exclusion statement is included in the Notice.

Directors recommendation

The Directors unanimously recommend that shareholders vote in favour of Resolution 1.

2. Resolution 2 - Ratification of Prior Issue of Placement Shares Issued under Listing Rule 7.1A

Background

On 27 June 2025, the Company issued a total of 155,364,808 of the Placement Shares as a portion of the Placement utilising the Company’s placement capacity under Listing Rule 7.1A. The Company

10948454v4

obtained Shareholder approval under Listing Rule 7.1A to issue up to an additional 10% of its fully paid issued capital at the Company’s 2024 Annual General Meeting.

Resolution 2 is seeking Shareholder ratification pursuant to Listing Rule 7.4 for the issue of the portion of the Placement Shares issued under Listing Rule 7.1A.

Listing Rule 7.4

A summary of Listing Rule 7.4 is set out in Section 1 above.

Information required by Listing Rule 14.1A

If Resolution 2 is passed, the portion of the Placement Shares detailed above will be excluded in calculating the Company’s 10% additional placement capacity in Listing Rule 7.1A, effectively increasing the number of Equity Securities the Company can issue without Shareholder approval over the 12 month period following the issue date.

If Resolution 2 is not passed, the portion of the Placement Shares detailed above will be included in calculating the Company’s 10% additional placement capacity in Listing Rule 7.1A, effectively decreasing the number of Equity Securities that the Company can issue without Shareholder approval over the 12 month period following the date of the 2024 AGM.

Information required by Listing Rule 7.5

The following information is provided for the purposes of Listing Rule 7.5:

10948454v4

3. Resolution 3: Approval of issue of Consideration Shares to shareholders of Fortify

Background

Overview of Acquisition

On 23 May 2025, the Company announced that it had entered into a binding term sheet to purchase all of the issued shares of Fortify Mining Pty Ltd ( Fortify ), the registered holder of the Majestic North Project and associated tenements ( Acquisition ).

The Majestic North Project is located approximately 65km east-south-east of Kalgoorlie in the Eastern Goldfield region of Western Australia ( Project ). The Project tenure covers 127 km² comprising one granted Mining Lease, one Exploration Licence and 14 Prospecting Licences. The Project includes a JORC 2012 compliant resource which is predominantly hosted within shallow, supergene-enriched mineralisation, offering potential advantages for future development scenarios.

Key terms of Acquisition

Orbminco entered into a binding term sheet with Fortify ( Agreement ) under which it will undertake detailed due diligence on the Project (including but not limited to a drilling program) and will be granted a 6-month exclusivity period during which it will complete confirmation drilling.

Following the six-month exclusivity period, completion of due diligence and satisfaction of various conditions precedent, Orbminco has the right to acquire 100% of the issued shares of Fortify for the following consideration:

(a) payment of $1 Million in cash;

• (b) $2.4 Million in OB1 shares based on an issue price of $0.001 ( Issue Price ); and

• (c) a production payment of $75 per oz of gold produced.

The Agreement is subject to various conditions precedent including among others:

• (a) all necessary shareholder approvals required under the ASX Listing Rules and Corporations Act 2001 to proceed with the Agreement;

• (b) Orbminco undertaking a capital raising within 30 business days of the execution of the term sheet (now satisfied);

• (c) receipt of any required regulatory or third-party consents or approvals; and

• (d) execution of a definitive share sale agreement and any other required formal agreements consistent with the Term Sheet.

Although the Company has not to date completed its due diligence on the Project, the Board wishes to have the necessary shareholder approvals in place in the event that the Company elects to proceed with the Acquisition. Accordingly, the Consideration Shares (as defined below) may not be issued in the event that the Acquisition does not proceed.

The Company notes that the ASX has confirmed that ASX Listing Rules 11.1.2 and 11.1.3 do not apply to the Acquisition.

Further material terms of the Acquisition are contained in the Company’s ASX announcement dated 23 May 2025.

Effect on Share Capital

As noted, the maximum Consideration Shares to be issued under the terms of the Agreement is 120,000,000 (post consolidation) ( Consideration Shares ).

10948454v4

The number of Consideration Shares is expressed on a post-consolidation basis assuming Resolution 9 is approved. Resolution 3 is not contingent upon the passing of Resolution 9. If Resolution 9 is not approved, the number of Consideration Shares will be approximately 2,400,000,000 at the Issue Price.

Following the issue of the Consideration Shares, the share capital of Orbminco will be as follows:

Shares on Issue¹	174,128,398
Maximum number of Consideration Shares as Upfront Consideration²	120,000,000
Shares on issuefollowingAcquisition	294,128,398

Notes:

¹ This assumes the Securities the subject of Resolutions 4-7 are approved by Shareholders at this Meeting and issued, and the Share Consolidation the subject to Resolution 8 is approved. ² Subject to rounding.

ASX Listing Rule 7.1

The purpose of the approval under this Resolution 3 is for Shareholders to approve the issue of the Consideration Shares to the shareholders of Fortify under the Acquisition.

ASX Listing Rule 7.1 provides that a company must not (subject to specified exceptions), without the approval of shareholders, issue or agree to issue during any 12 month period any Equity Securities, or other securities with rights to conversion to equity (such as an option), if the number of those securities exceeds 15% of the number of ordinary securities on issue at the commencement of that 12 month period.

Given the Consideration Shares the subject of this Resolution 3 will exceed the 15% threshold set out in ASX Listing Rule 7.1, and none of the exceptions contained in Listing Rule 7.2 apply, Shareholder approval is required under ASX Listing Rule 7.1. The effect of Resolution 3 will be to allow the Company to issue the Consideration Shares during the period of 3 months after the Meeting (or a longer period, if allowed by ASX), without using the Company’s 15% annual placement capacity.

Information required by ASX Listing Rule 14.1A

If Resolution 3 is passed, the Company can proceed with the issue of the Consideration Shares the subject of this Resolution 3 and such securities will be excluded in calculating the Company’s 15% limit in ASX Listing Rule 7.1, effectively increasing the number of Equity Securities the Company can issue without Shareholder approval over the 12 month period following the issue date.

If Resolution 3 is not passed, the Company will not be able to proceed with the issue of the Consideration Shares and the Acquisition on the current terms.

Information required by ASX Listing Rule 7.3

The following information is provided for the purposes of ASX Listing Rule 7.3:

• (a) the maximum number of Consideration Shares to be issued is 120,000,000 (on a post consolidation basis) and 2,400,000,000 (on a pre-consolidation basis);

• (b) the Consideration Shares the subject of this Resolution 3 are proposed to be issued no later than 3 months after the date of the Meeting;

• (c) the issue price of the Consideration Shares will be $0.02 per Share (on a post consolidation basis) and $0.001 (on a pre-consolidation basis);

• (d) the Consideration Shares the subject of this Resolution 3 will be issued to the Fortify Shareholders and none of those investors will be related parties of the Company;

• (e) the Consideration Shares to be issued will be fully paid ordinary shares in the capital of the Company issued on the same terms and conditions as the Company’s existing Shares;

• (f) the material terms of the agreement under which the Consideration Shares are to be issued is set out above under ‘Key Terms of the Acquisition’;

10948454v4

• (g) the Consideration Shares will be issued for nil consideration as they are being issued as part of the consideration for the Acquisition. Accordingly, no funds will be raised by the issue of the Consideration Shares; and

• (h) a voting exclusion statement is included in the Notice.

Recommendation of the Board

Accordingly, the Directors unanimously recommend that Shareholders vote in favour of Resolution 3.

4. Resolutions 4, 5, 6 and 7 – Approval of issue of Placement Shares to Ian Gordon, David Richards, Ralf Kriege and David Lindh

Background

On 23 May 2025, the Company announced a Placement to raise approximately $2.3m as detailed above in the background to Resolution 1 and 2. Included in this amount was a commitment by Directors Ian Gordon, David Richards, Ralf Kriege and David Lindh to participate in the capital raise on the same terms as all the other investors, subject to the Company obtaining Shareholder approval to the issue (‘ Director Shares’ ).

The number of Director Shares is expressed on a post-consolidation basis assuming Resolution 9 is approved. Resolutions 4,5, 6 and 7 are not contingent upon the passing of Resolution 9. If Resolution 9 is not approved, the number of Director Shares will be approximately 80,000,000 (20,000,000 to each Director) at anissue price of $0.001 per Share.

Listing Rule 10.11

Listing Rule 10.11 requires shareholder approval to be obtained where an entity issues, or agrees to issue, securities to a related party (among others), unless an exception in Listing Rule 10.12 applies.

Mr Gordon, Mr Richards, Mr Kriege and Mr Lindh are related parties of the Company by virtue of being Directors of the Company. As the issue of the Director Shares is the issue of securities to a related party of the Company, shareholder approval is required unless an exception applies. It is the view of the Board that the exceptions set out in Listing Rule 10.12 do not apply in the current circumstances.

Accordingly, Shareholder approval is being sought for the issue of a total of 4,000,000 Director Shares to Mr Gordon, Mr Richards, Mr Kriege and Mr Lindh (or their nominees) on the terms set out below and as detailed in the table below.

**Director **	Director Shares	Funds Raised	**Resolution **
IanGordon	1,000,000	$20,000	4
DavidRichards	1,000,000	$20,000	5
DavidLindh	1,000,000	$20,000	6
Ralf Kriege	1,000,000	$20,000	7
**Total **	4,000,000	$80,000

If approval to issue the Director Shares is given under Listing Rule 10.11, approval is not required under Listing Rule 7.1. The Director Shares must be issued within one month of this meeting, as per Listing Rule 10.13.5.

Corporations Act

For a public company or an entity that the public company controls, to give a financial benefit to a related party of the public company, the public company or entity must:

• (a) obtain the approval of the public company's members in the manner set out in sections 217 to 227 of the Corporations Act; and

10948454v4

• (b) give the benefit within 15 months following such approval,

unless the giving of the financial benefit falls within an exception set out in sections 210 to 216 of the Corporations Act.

It is considered that Shareholder approval under Chapter 2E of the Corporations Act is not required for the purposes of the issue of the Director Shares, pursuant to Resolutions 4, 5 and 6, on the basis that the exception in section 210 of the Corporations Act applies as Mr Gordon, Mr Richards, Mr Kriege and Mr Lindh are proposing to participate in the Placement on the same terms as the other applicants.

Information required by Listing Rule 14.1A

If Resolutions 4, 5, 6 and 7 are passed, the Company will be able to proceed with the issue of the Director Shares to Messrs Gordon, Richards, Kriege and Lindh within one month after the date of the Meeting. As approval pursuant to Listing Rule 7.1 is not required for the issue of the Director Shares (because approval is being obtained under Listing Rule 10.11), the issue of the Director Shares will not use up any of the Company’s 15% annual placement capacity.

If Resolutions 4, 5, 6 and 7 are not passed, the Company will not be able to proceed with the issue of the Director Shares to Messrs Gordon, Richards, Kriege and Lindh. Resolutions 4, 5, 6 and 7 are each an independent Resolution. Resolutions 4, 5, 6 and 7 seek Shareholder approval for the purposes of Listing 10.11 for the issue of the Director Shares.

Information required by ASX Listing Rule 10.11

For the purposes of Listing Rule 10.13, the Company provides the following information:

• (a) the Director Shares will be issued to Mr Ian Gordon (Resolution 4), Mr David Richards (Resolution 5), Mr David Lindh (Resolution 6) and Mr Ralf Kriege (Resolution 7)(or their nominees), Directors of the Company and persons falling within the definition of Listing Rule 10.11.1;

• (b) the maximum number of Director Shares to be issued is:

• (i) 1,000,000 Director Shares to Mr Ian Gordon (or nominee) on a post consolidation basis and 20,000,000 Director Shares on a pre-consolidation basis;

• (ii) 1,000,000 Director Shares to Mr David Richards (or nominee) on a post consolidation basis and 20,000,000 Director Shares on a pre-consolidation basis;

• (iii) 1,000,000 Director Shares to Mr David Lindh (or nominee) on a post consolidation basis and 20,000,000 Director Shares on a pre-consolidation basis;

• (iv) 1,000,000 Director Shares to Mr Ralf Kriege (or nominee) on a post consolidation basis and 20,000,000 Director Shares on a pre-consolidation basis.

• (c) the Director Shares will be issued at an issue price of $0.02 per Share (on a post consolidation basis) and an issue price of $0.001 per Share (on a pre-consolidation basis);

• (d) the Director Shares are proposed to be issued no later than 1 month after the date of the Meeting;

• (e) the Director Shares to be issued will be fully paid ordinary shares in the capital of the Company issued on the same terms and conditions as the Company’s existing Shares;

• (f) the funds raised from this issue will be used to fund exploration at the Majestic North Project and working capital; and

• (g) a voting exclusion statement is included in the Notice.

Recommendation of the Board

Mr Gordon, Mr Richards, Mr Lindh and Mr Kriege decline to make a recommendation to Shareholders in relation to Resolutions 4, 5, 6 and 7 respectively due to their material personal interest in the outcome of these Resolutions on the basis that they are each to be issued 1,000,000 Director Shares (on a postconsolidation basis) or 20,000,000 Director Shares (on a pre-consolidation basis) should Resolutions 4, 5, 6 and 7 be passed.

10948454v4

The Directors (other than the Resolution that relates to their own interest) recommend that Shareholders vote in favour of Resolutions 4, 5, 6 and 7.

The Directors make the recommendation above for the following reasons:

• (a) the issue of the Director Shares will better align the interests of Mr Gordon, Mr Richards, Mr Lindh and Mr Kriege with those of Shareholders;

• (b) the issue of the Director Shares is reasonable and appropriate as Mr Gordon, Mr Richards, Mr Lindh and Mr Kriege are proposing to participate in the Company’s capital raising activity on the same terms as other applicants; and

• (c) it is not considered that there are any significant opportunity costs to the Company or benefits foregone by the Company in issuing the Director Shares on the terms proposed.

The Chair of the Meeting intends to vote all undirected proxies in favour of Resolutions 4, 5, 6 and 7.

5. Resolution 8 – Approval of issue of Broker Options

Background

The Company had engaged Cerberus Investments Pty Ltd (ACN 107652737) trading as Cerberus Advisory ( Cerberus ) as lead manager to the Placement pursuant to a lead manager mandate ( Lead Manager Mandate ).

Under the terms of the Lead Manager Mandate, the Company had agreed to provide the following consideration to Cerberus:

• (a) payment of a lead management fee of 6% of the proceeds of the Placement (excluding GST); and (b) issue 130,000,000 unlisted Options (6,500,000 unlisted Options on a post consolidation basis) exercisable at $0.002 ($0.04 on a post consolidation basis) each on or before the date that is three (3) years from the date of issue ( Broker Options ).

The number of Broker Options is expressed on a post-consolidation basis assuming Resolution 9 is approved. Resolution 8 is not contingent upon the passing of Resolution 9. If Resolution 9 is not approved, the number of Lead Manager Options will be approximately 130,000,000 unlisted Options exercisable at $0.002 each.

A summary of Listing Rule 7.1 is set out in Section 3 above. As summarised in Section 3, Listing Rule 7.1 limits the amount of equity securities that a listed company can issue without the approval of its shareholders over any 12 month period to 15% of the fully paid ordinary shares it had on issue at the start of that period.

Information required by Listing Rule 14.1A

If Resolution 8 is passed, the Company will be able to proceed with the issue of the Broker Options. In addition, the issue of the Broker Options will be excluded from the calculation of the number of equity securities that the Company can issue without Shareholder approval under Listing Rule 7.1.

If Resolution 8 is not passed, the Company will not be able to proceed with the issue of the Broker Options.

Information required by Listing Rule 7.1

The following information is provided for the purposes of ASX Listing Rule 7.3:

• (a) the Broker Options will be issued to Cerberus (or its nominees);

• (b) in accordance with paragraph 7.2 of ASX Guidance Note 21, the Company confirms that none of the recipients will be:

10948454v4

• (i) related parties of the Company, members of the Company’s Key Management Personnel, substantial holders of the Company, advisers of the Company or an associate of any of these parties; and

• (ii) issued more than 1% of the issued capital of the Company;

• (c) the maximum number of Broker Options to be issued is 6,500,000 (on a post consolidation basis) or 130,000,000 (on a pre-consolidation basis),

• (d) the terms and conditions of the Broker Options are set out in Schedule 1;

• (e) the Broker Options will be issued no later than 3 months after the date of the Meeting (or such later date to the extent permitted by any ASX waiver or modification of the Listing Rules) and it is intended that issue of the Broker Options will occur on the same date;

• (f) the Broker Options will be issued at a nil issue price, in consideration for the services provided by Cerberus under the Lead Manager Mandate;

• (g) the purpose of the issue of the Broker Options is to satisfy the Company’s obligations under the Lead Manager Mandate;

• (h) the Broker Options are being issued to Cerberus under the Lead Manager Mandate;

• (i) a summary of the material terms of the Lead Manager Mandate is summarised above; and

• (j) the Broker Options are not being issued under, or to fund, a reverse takeover.

6. Resolution 9 – Consolidation of Capital

Background

The Board has resolved that this resolution be put to Shareholders to consider, and if thought fit approve, a 20:1 consolidation of the Company’s Shares ( Consolidation ) for the purposes of section 254H of the Corporations Act, the Company’s Constitution and for all other purposes.

Section 254H of the Corporations Act provides that a company may convert all or any of its shares into a larger or smaller number of shares subject to the approval of shareholders at a general meeting. Listing Rule 7.20 provides that if an entity proposes to reorganise its capital, it must advise shareholders of certain matters which are set out below.

No voting exclusions apply, and all Shareholders can vote on the Resolution. If this Resolution is approved by Shareholders, this consolidation will take effect on 18 September 2025 ( Consolidation Effective Date ).

Reasons for the Consolidation

The Consolidation is proposed by the Company to reduce its total issued capital to a more appropriate and effective capital structure for continued growth for existing shareholders and a resultant share price that is more appealing to a wider range of investors.

Effect of the Consolidation

As at the date of this Notice the effect of the consolidation of the Company’s issued capital is set out below.

Option Class	Pre- Consolidation No.	Pre- Consolidation Exercise Price	Post- Consolidation No.	Post- Consolidation Exercise Price

Fractional Entitlements

Where the Consolidation would result in a fractional entitlement to a Share or Option, that fractional entitlement will be rounded to the nearest whole Share or Option, with fractions of 0.5 rounded up to the nearest whole Share or Option as applicable. The consolidation will have no effect on the Company’s assets or liabilities.

10948454v4

Schedule 1 – Terms and Conditions of Broker Options

Entitlement

Each New Option gives the Optionholder the right to subscribe for one Share. To obtain the right afforded by each Option, the Optionholder must exercise the relevant Options in accordance with the terms and conditions attaching to the Options. Subject to variation in the share capital of the Company, the amount payable by the Optionholder on the exercise of each option shall be $0.04 (on a post consolidation basis) ( Exercise Price ).

Exercise

The Options will expire on the date which is 3 years from the date of issue ( Option Expiry Date ), unless exercised earlier pursuant to the terms and conditions of the Options. Any Option not exercised before the Option Expiry Date will automatically lapse on the Option Expiry Date.

The Options shall be exercisable at any time on or prior to the Option Expiry Date by the Optionholder providing a notice in writing to the Company and payment of the Exercise Price in cleared funds ( Exercise Notice ). Within 10 business days of receipt of the Exercise Notice, the Company will:

• (a) allot and issue such number of Shares in the Company as required by the terms and conditions with reference to the number of Options specified in the Exercise Notice;

• (b) if required, provide the ASX with a notice that complies with section 708A(5)(e) of the Corporations Act or, if the Company is unable to issue such a notice or such notice is not effective, lodge with ASIC a prospectus prepared in accordance with the Corporations Act and do all things necessary to ensure that an offer for sale of Shares does not require disclosure to investors pursuant to section 708A(11) of the Corporations Act.

Rank equally

Shares issued on the exercise of the Options will rank equally with the Shares on issue at the time of the exercise. If the Company is admitted to the official list of the ASX on the date of the exercise of the Options, application will be made by the Company to the ASX for official quotation of the Shares that result from the exercise of the relevant Options.

Rights attaching to Options

If at any time the issued capital of the Company is reconstructed, the number of Options and the Exercise Price will be adjusted accordingly, in a manner that the auditors of the Company advise is fair and reasonable in their option, and in all cases in accordance with the provisions of the Listing Rules and the Corporations Act. Other than for such an adjustment, an Option does not confer the right to a change in Exercise Price or a change in the number of underlying securities over which the Option is capable of exercise.

There are no participation rights or entitlements inherent in the Options, and Optionholders will not be entitled to participate in new issues of capital offered to shareholders by virtue of the Options. The Company will notify all Optionholders that hold Options capable of exercise prior to the relevant qualifying date for the new issue of capital no less than 10 business days prior to the closing date of that offer, so as to enable those Optionholders to exercise some or all of their Options such that they may then participate in the relevant issue of capital.

Options not Quoted

The Options will not be quoted on the ASX.

10948454v4

Compliance with Listing Rules

If, and to the extent, any of the preceding terms and conditions in respect of the Options are inconsistent with the Listing Rules, the Listing Rules will prevail in all respects to the extent of the inconsistency.
