(a) The rights and obligations of an Eligible Employee under the terms of his or her office, employment or contract with the Group are not affected by his or her participation in the Plan.

13.7 Non-residents of Australia

(e) Rights to US Eligible Employees. The Company intends that all Rights granted to US Eligible Employees be structured to comply with, or be exempt from, Section 409A of the US Tax Code, such that no adverse tax consequences, interest, or penalties under Section 409A of the US Tax Code apply, and the Plan and all Rights granted hereunder to US Eligible Employees shall be interpreted and administered in a manner consistent with such intention. In the event any provision of the Plan or any Right granted to a US Eligible Employee would cause a Right granted to a US Eligible Employee to fail to be exempt from, or to comply with, Section 409A of the US Tax Code, the Plan and/or such Right shall be amended to the extent necessary to ensure such Right is so exempt and/or compliant in a manner that no additional tax shall apply to the US Eligible Employee with respect to such Right. Notwithstanding anything in the

Bionomics Limited Employee Equity Planv 2.0

Plan or any Invitation to the contrary, the Board may, without an Eligible Employee’s consent, amend this Plan or Rights, adopt policies and procedures, or take any other actions (including amendments, policies, procedures and retroactive actions) as are necessary or appropriate to preserve the intended tax treatment of Rights, including any such actions intended to (A) exempt any Right from Section 409A of the US Tax Code, or (B) comply with Section 409A of the US Tax Code, including regulations, guidance, compliance programs and other interpretative authority that may be issued after a Right’s date of grant. The Company makes no representations or warranties as to a Right’s tax treatment under Section 409A of the US Tax Code or otherwise. The Company will have no obligation under this Plan or any Right to avoid the taxes, penalties or interest under Section 409A of the US Tax Code with respect to any Right and will have no liability to any Eligible Employee or any other person if any Right, compensation or other benefits under the Plan are determined to constitute noncompliant “nonqualified deferred compensation” subject to taxes, penalties or interest under Section 409A of the US Tax Code.

13.8 Personal information

The Participant consents to the Company or its agents (and each of their related parties) collecting, holding and using personal information (including a Participant’s tax file number) that the Participant provides in the application to participate in the Plan or otherwise provides to the Company or its agents (and each of their related parties) as part of their employment, in order to carry out the administration and operation of the Plan in accordance with the Plan Rules, including providing relevant information to:
