Letter from the Chairman (Share Purchase Plan)

Dear Shareholder,

On 4 October 2021 the Board of Directors of Archer Materials Ltd (“Archer”, the “Company”) announced a $20 million equity raise to fund the development and growth of the Company’s advanced semiconductor technologies, with a particular focus on the[12] CQ quantum computing chip. The equity raise comprises a:

• $15 million share placement to sophisticated and professional investors at a price of $1.45 per share (“Placement”); plus

• $5 million share purchase plan at a price of $1.45 per share (“SPP”).

Share Purchase Plan

With the recent Archer shareholder approval for the sale of the Company’s remaining mineral exploration tenements and the iTech Minerals Ltd initial public offering, the Company’s transition from a mineral exploration company to a deep technology company is almost complete. With the recent grants of the[12] CQ quantum chip related patents, and the anticipated easing of COVID-19 restrictions and resumption of international travel, the Archer board has made the decision to raise funds to expedite our work and actively engage with potential overseas development partners and commercial end-users.

The SPP allows eligible shareholders (who are residents of Australia or New Zealand and held Archer shares at 7:00pm (Sydney time) on Friday 1 October 2021 (“Eligible Shareholder”) to apply for up to $30,000 of new Archer shares (“New Shares”) and a minimum of $2,500 of Shares without incurring brokerage or transaction costs. The issue price of $1.45 per Share is the same as the issue price for institutional and sophisticated investors under the recent Placement.

The SPP is targeting to raise $5 million. Please note that if total demand for the SPP exceeds $5 million then the Board reserves the right to close the SPP early and scale back applications or elect to increase the amount raised under the SPP.

Use of funds

It is intended that the funds raised from the SPP will be used towards:

• (a) Progressing Archer’s world-first technology development, including its[12] CQ chip and Biochip.

• (b) Utilising world-class technology development infrastructure and facilities, R&D, people, and IP, to support pre-market development of Archer’s technologies.

• (c) Protecting intellectual property assets (e.g. patents and international patent applications) underpinning the Company’s technology.

• (d) Establishing and strengthening new and existing commercial partnerships in Australia and abroad.

• (e) General working capital requirements.

1. Access the Company's SPP offer website: https://axespp.thereachagency.com to apply online.

2. Enter your personal holder ID (SRN or HIN) shown on the top right of this letter (to the right of your address) and your postcode or domicile.

2. Purpose

The Share Purchase Plan offers Eligible Shareholders of Archer Materials Limited the opportunity to subscribe for new fully paid ordinary shares in the Company (“New Shares”), up to a maximum value of $30,000 (subject to any discretionary scale backs and any restrictions imposed by law).

New Shares under the Plan will be issued at a price of $1.45 each (“Issue Price”) being the same price paid by sophisticated and institutional investors under the share placement announced on 4 October 2021 (“Placement”).

The SPP is targeting to raise $5,000,000. If the Company receives Applications for an amount more than $5,000,000, then the Company may elect to either scale back Applications or increase the amount to be raised under the SPP. In the event of a scale back, you will be allocated less than the number of New Shares that you applied for.

3. Raising Amount and Scaleback

The SPP is targeting to raise $5,000,000, however the Company reserves absolute discretion regarding the final amount raised under the Plan. If total demand for the SPP exceeds $5,000,000, then the Company reserves the right to:

• (a) elect to increase the amount raised (subject to the maximum amount permitted under the ASX Listing Rules); or

• (b) close the SPP early and scale back Applications. When determining the amount (if any) by which to scale back an Application, the Company may take into account a number of factors, including the size of an applicant’s shareholding, the extent to which Eligible Shareholders have sold or bought additional Shares after the Record Date and the date an Application was made. Eligible Shareholders are therefore encouraged to submit their Applications early.

If there is a scale back, then you may not receive all the New Shares for which you have applied. If the Company rejects or scales-back an Application or purported Application, then the Company will promptly return to the Shareholder the relevant Application monies, without interest. If the amount received is less than the minimum Application amount of $2,500 then Archer will not issue any New Shares to you and the money received from you will be refunded without interest.

Archer reserves the right to reject any Application for New Shares under the SPP that it believes does not comply with these Terms and Conditions.

5. Shareholders eligible to participate in the Plan

Holders of Shares that were registered on the Company share register as a holder of Shares on the Record Date with an address in Australia or New Zealand are deemed eligible shareholders (“Eligible Shareholders”) and may participate in the Plan.

If you hold Shares on behalf of persons who reside outside Australia or New Zealand (particularly in the United States), then you are not an Eligible Shareholder and are not entitled to participate in the Plan. Due to foreign securities laws, it is not practical for Shareholders (or beneficial Shareholders) resident in other countries to be offered the opportunity to participate in the Plan.

The SPP allows Eligible Shareholders to increase their investment in the Company by buying discounted New Shares at a fixed price without the need to pay brokerage and commission costs.

Participation in the Plan is optional and is subject to these Terms and Conditions. Offers made under the Plan are non-renounceable (i.e. Eligible Shareholders cannot transfer their rights to any New Shares offered under the Plan).

Details of how Custodians, trustees and beneficiaries are treated under the Plan are provided further below.

6. Important Information

Before you apply for New Shares under the Plan, you should consider obtaining professional financial and/or taxation advice to assist you in determining whether or not, and the extent to which, you wish to participate in the Plan (taking into account your own financial situation, needs and objectives).

The Company and its officers make no recommendation about whether or not you should apply for New Shares under the Plan and nothing in these Terms and Conditions (including the Application) or any other accompanying documentation constitutes investment or financial product advice or is intended to influence your decision whether or not to participate in the Plan.

7. Joint holders/joint beneficiaries

If two or more persons are registered on the Company share register as jointly holding Shares, then they are taken to be a single registered holder of Shares and a certification given by any of them is taken to be a certification given by all of them. If the same joint holders receive more than one offer under the Plan due to multiple identical holdings, then the joint holders may only apply in aggregate up to the maximum amount of $30,000.

8. New Zealand

The New Shares offered under the Plan are not being offered or sold to the public within New Zealand other than to existing Shareholders of the Company with registered addresses in New Zealand and to whom the Offer is being made in reliance on the Financial Markets Conduct (Incidental Offers) Exemption Notice 2016 (New Zealand) (as amended by the Financial Markets Conduct (Incidental Offers) Exemption Amendment Notice 2018 ).

This document has not been registered, filed with or approved by any New Zealand regulatory authority under the Financial Markets Conduct Act 2013 (New Zealand). This document is not an investment statement or prospectus under New Zealand law and is not required to, and may not, contain all the information that an investment statement or prospectus under New Zealand law is required to contain.

9. Foreign offer restrictions

The Plan may not be released or distributed in any country other than Australia or New Zealand. The Plan does not constitute an offer to sell, or a solicitation of an offer to buy, securities in any other country, other than Australia or New Zealand.

SPP October 2021

Page 5 of 13

Archer Materials Limited (ACN: 123 993 233)

10. Not for distribution or release in the United States

The SPP Shares offered and sold under the SPP have not been, and will not be, registered under the U.S. Securities Act of 1933, as amended (the "U.S. Securities Act") or the securities laws of any state or other jurisdiction of the United States. Accordingly, you are not eligible to participate in the SPP if you are in the United States or are acting for the account or benefit of a person in the United States. If you are acting for the account or benefit of a person in the United States, you are not permitted to apply for or acquire SPP Shares for, or for the account or benefit of, that person.

11. New Share issue price

New Shares will be issued at $1.45 (“Issue Price”), being the same price paid by sophisticated and institutional investors under the Placement. The Issue Price represents a discount of:

• (a) 16.4% to the closing price of Archer shares on 30 September 2021, which was the last trading day prior to the date of the announcement of the SPP;

• (b) 52.9% to the Archer 52-week high share price of $3.08 achieved on 16 August 2021; and

• (c) 20.9% to the volume weighted average price of Archer shares over the five trading days prior to the date of the announcement of the SPP on 1 October 2021.

You should note that the Archer share price may rise or fall between the date of this Offer and the date when New Shares are allotted and issued to you under the SPP. This means that the price you pay per New Share under this Offer may be either higher or lower than the Archer share price quoted on ASX at the time of the Offer or at the time the New Shares are issued and allotted to you under the SPP.

The Board recommends that you obtain your own financial advice in relation to the Offer under the SPP and consider price movements of Shares in the Company prior to making an Application under this SPP.

12. How much can you invest?

Eligible Shareholders may apply for a maximum of $30,000 and a minimum of $2,500 worth of New Shares under the SPP. These limitations apply even if you receive more than one Application, or if you hold Shares in more than one capacity. It is your responsibility to ensure that the number of New Shares issued to you does not exceed $30,000 in aggregate.

Subject to the above, Eligible Shareholders may participate in the SPP by selecting one of the following offers to purchase New Shares under the Plan.

	Subscription amount	Number of New Shares to be issued at $1.45 per New Share
Minimum application	$2,500	1,725
	$5,000	3,449
	$10,000	6,897
	$15,000	10,345
	$20,000	13,794
	$25,000	17,242
Maximum application	$30,000	20,690

Eligible Shareholders are encouraged to submit their Applications early as the Directors reserve the right to close the SPP early or scale back the amount of News Shares issued, if the SPP is oversubscribed.

SPP October 2021

Page 6 of 13

Archer Materials Limited (ACN: 123 993 233)

If you apply for New Shares under the Plan, you are applying for a certain value of New Shares at the Issue Price of $1.45, rather than a certain number of Shares. Fractional New Shares will not be issued and any fraction of a New Share will be rounded up to the nearest whole number of New Shares.

In the absence of a scale back described in section 3 above, the Company will divide the amount of the BPay or EFT payment received from you by the Issue Price in order to determine the number of New Shares for which you have applied (rounded up to nearest whole number of New Shares). If we receive an amount that does not equal one of the amounts specified in the table above, then Company may either:

• (a) reject the Application and refund in full the application money (without interest) to you; or

• (b) apply the dollar amount of the payment to the highest designated parcel that is less than the amount of the payment and refund the excess application money (without interest) to you.

13. How do you apply for New Shares?

To apply for New Shares under the SPP, complete your Application online at https://axespp.thereachagency.com.

Applications for New Shares under the SPP can only be made by:

• BPay® for Australian Eligible Shareholders and New Zealand Eligible Shareholders with an Australian bank account; or

• by EFT for New Zealand Eligible Shareholders who don’t have an Australian bank account or do not wish to pay via BPAY®.

When paying by BPay® or EFT you are not required to submit a physical application form but when making payment are taken to make the certifications and representations described in these Terms and Conditions and the Application. However, Custodians applying for Beneficiaries must still complete and return a Custodian Certificate.

Eligible Shareholders wishing to pay by BPay® or EFT must access a personalised customer reference number or EFT transaction identification before making payment. You can access your customer reference number or EFT identification as follows:

• (a) Access the Company's SPP offer website: https://axespp.thereachagency.com.

13.2 Payment by BPay or EFT

To pay by BPay®, access your bank account and enter the personalised customer reference number and biller code gained from following the steps described above (refer to section 13.1(c)(i).

Your payment will not be accepted if it is not received by the Company by 5:00pm (Sydney time) on the Closing Date and no New Shares will be issued to you in respect of that Application.

Applicants should be aware that their own financial institution may implement earlier cut off times with regards to electronic payment, and should therefore take this into consideration when making payment. You may also have your own limit on the amount that can be paid via BPay® or EFT. It is your responsibility to check that the amount you wish to pay for New Shares does not exceed your limit.

Once your BPay® or EFT payment is made, it cannot be revoked.

13.3 Multiple Applications

If you have multiple holdings and make multiple online Applications then you will have multiple BPay® customer reference numbers or EFT transaction identification numbers. To ensure you receive your New Shares under the Offer in respect of that holding, you must use the specific customer reference number or EFT transaction identification number (as applicable) shown on each personalised Application that you wish to apply for in respect of that holding.

If you inadvertently use the same customer reference number or EFT transaction identification number for more than one of your Applications, you will be deemed to have applied only for the Application to which that Customer Reference Number or EFT transaction identification number applies and any excess amount will be refunded.

Any Eligible Shareholder that pays for New Shares by BPay® or EFT is deemed to represent to the Company that the amount of Shares subscribed for pursuant to the Plan does not exceed $30,000 (including joint or any other beneficial interests).

13.4 Applications by Custodians

If you wish to apply as a Custodian under the SPP to receive New Shares for one or more Eligible Beneficiaries, you must complete and submit an additional Custodian Certificate that contains further certifications and details (as required under the terms of ASIC Corporations (Share and Interest Purchase Plans) Instrument 2019/547 ) before your Application will be accepted.

Applications by Custodians that are not accompanied by a duly completed Custodian Certificate will be rejected. To request a Custodian Certificate, you should contact Computershare Investor Services Pty Limited and if you would like further information on how to apply, please contact Mr Damien Connor, Archer Materials Limited Company Secretary on +61 8 8272 3288 or at hello@archerx.com.au.

Custodians are not permitted to participate in the SPP on behalf of, and must not distribute these Terms and Conditions or any documents (including the Letter) relating to this SPP to, any person in the United States.

14. Shortfall

SPP October 2021

15. Archer’s discretions regarding Applications

• (a) your BPay® or EFT payment (as the context requires) is not received or is incomplete or invalid by the Closing Date;

• (b) unless you are applying as a Custodian, it appears that you are applying to buy more than $30,000 (in aggregate) of New Shares under the SPP;

• (c) you are a Custodian, Archer is not satisfied with your certification for any reason, or if you have not provided certification in accordance with these Terms and Conditions;

19. No Underwriting

The Plan is not underwritten.

21. Modification and Termination of the Plan

The Company may modify or terminate the Plan, or waive strict compliance with any of the Terms and Conditions, at any time and any modification, waiver or termination is binding on all Eligible Shareholders even where the Company does not notify you of that event.

In the event the Plan is terminated before the issue of New Shares, all application monies will be returned to you, without interest, by direct credit to your nominated account as recorded on the Company’s share register or cheque to your address as shown on the Company’s share register as soon as practicable.
