Subject to clauses 2 and 3 of this Schedule and any restrictions imposed by the Australian Securities Exchange (ASX}, each Option is exercisable at any time after the date on which the relevant Option has vested (Vesting Date) up and until the expiry date being 30 November 2028 (Expiry Date). Any Options not exercised by the Expiry Date will automatically lapse on the Expiry Date.

The aggregate of 15,000,000 Options is subject to vesting conditions based on tenure of Dr Perry, (ii) the Company's Share Price and (iii) milestone performance by the Company as follows:

Tenure - A tranche of 3,333.333 Options, with 1,666,666 which the Company acknowledges have already vested prior to the date of this deed in accordance with the tenure conditions as specified in the Company's 2018 AGM notice, and 1,666,667 to vest on 1 June 2020;

Company Share Price - In aggregate the Company acknowledges that a further 9,166,667 Options have prior to the date of this deed already vested in Dr Perry in accordance with the share price vesting conditions as specified in the Company's 2018 AGM notice;

Milestone Performance - Provided Dr Perry is still employed by the Company, a further tranche of 2,500,000Options to vest upon the achievement of the milestones “Initial procurement under the BARDA contract” under CLIN2 of the BARDA contract for 5,614 ReCell devices totaling USD $7,594,620.

The Options may be exercised for part or all of the Options issued by the Option Holder giving written notice in the form set out below (Notice of Exercise) to the Company at its registered office prior to the Expiry Date.

On exercise the Company will issue to the holder for each Option exercised one ordinary share in the capital of the Company credited as fully paid. The exercise price per Option is $0.082 per Share (Exercise Price).

On receipt by the Company of the Notice of Exercise and payment of the Exercise Price, the Company must, within 3 Business Days and if the Shares are listed on the ASX within the time period prescribed by the Listing Rules of the ASX (ASX Listing Rules):

allot to the Option Holder one Share in the Company for each Option exercised by the Option Holder;

cause to be dispatched to the Option Holder the relevant acknowledgement of issue, a holding statement or share certificate (as applicable) as soon as is reasonably practicable detailing the issue of the relevant Share/s; and

issue (if applicable) a new holding statement (or option certificate) for the balance of the Options that remain unexercised.

Shares allotted on the exercise of Options will rank equally in all respects with the then existing issued ordinary fully paid shares in the capital of the Company (except in respect to any dividends which shall have been declared but not yet distributed before the actual exercise of an Option) and will be subject to the provisions of the Constitution of the Company.

If any Reorganization (including consolidation, subdivision, reduction, return or cancellation) of the issued capital of the Company occurs before the expiry of any Options, the number of Options to

which each Option Holder is entitled or the Exercise Price of his or her Options or both must be reorganized in accordance with the ASX Listing Rules applying to a Reorganization at the time of the Reorganization (which adjustment formula will apply even where the Company is not admitted to the ASX Official List).

An Option does not confer the right to participate in new issues of capital offered to holders of Shares (Rights Entitlement) during the currency of the Options without exercising the Options. However, the Company will ensure that for the purpose of determining Rights Entitlements to any such issue, the Option Holder is to receive at least 10 Business Days written notice from the Company of the pending closing or record date and sufficient time for the Option Holder to exercise the Options prior to that closing or record date in order to qualify for the participation in the Rights Entitlement.

If the Shares are listed for quotation on the ASX, the Company will apply to the ASX for, and will use its best endeavours to obtain, quotation or listing of all Shares allotted on the exercise of any Options within 10 Business Days (as defined in the Listing Rules of the ASX) of allotment. In the event that the Company undergoes a reorganization that results in the conversion of Shares quoted on the ASX into shares quoted on another exchange, then the Company will apply to the relevant exchange and for securities regulator as required for those converted shares related to the Option shares to be quoted.

In the event of the Liquidation of the Company, all unexercised Options will lapse upon the occurrence of that Liquidation.

The Options do not provide any entitlement to dividends paid to ordinary shareholders.

The Options do not entitle the Option Holder to vote at any meeting of shareholders.

To the extent (if any) that any of these Option Terms and Conditions or this Deed are inconsistent with or contrary to the ASX Listing Rules, the ASX Listing Rules provisions will prevail and these Option Terms and Conditions are deemed to incorporate the relevant ASX Listing Rules provisions as an amendment to these terms; and

These Terms and Conditions are governed by the laws of Victoria. The parties submit to the non-exclusive jurisdiction of the courts of Victoria.
