Severance
If,
at any time, (a) the Company terminates your employment without Cause (as defined herein), and other than as a result of your death or
disability, or (b) you resign for Good Reason (as defined herein), and provided such termination constitutes a “separation from
service” (as defined under Treasury Regulation Section 1.409A-1(h)), you shall be entitled to receive the following severance benefits:
| (a) | if
in Connection with a Change in Control: you shall be entitled to (i) severance pay in
the form of monthly payments equal to 12 months of your base salary in effect on the effective
date of termination, (ii) a lump sum payout of a pro-rata bonus for the bonus year, based
on good faith estimates of the achievement of performance goals on the date of termination,
and (iii) if you timely elect continued health care coverage under COBRA, the Company shall
pay the same proportion of your premium rate for you and your eligible dependents as before
the date of termination or, if COBRA coverage is not available, then the Company shall reimburse
you for such amount (in the same proportion as before the termination) through the earlier
of (A) 6 months following the Separation from Service, or (B) the date upon which you and
your eligible dependents become covered under similar plans (and you agree to notify the
Company of such other coverage); |
| (b) | if
other than in Connection with a Change in Control: (i) subject to the requirement to
mitigate below, you shall be entitled to severance pay in the form of monthly payments equal
to a maximum of 6 months of your base salary in effect on the effective date of termination,
(ii) a lump sum payout of a pro-rata bonus for the year, based on good faith estimates of
the achievement of performance goals on the date of termination, and (iii) if you timely
elect continued health care coverage under COBRA, the Company shall pay the same proportion
of your premiums for you and your eligible dependents as before the date of termination or,
if COBRA coverage is not available, then the Company shall reimburse you for such amount
(in the same proportion as before the termination) through the earlier of (A) 6 months following
the Separation from Service, or (B) the date upon which you and your eligible dependents
become covered under similar plans (and you agree to notify the Company of such other coverage). |
Such
severance benefits are conditional upon (a) your continuing compliance with your obligations under your Confidentiality Agreement and
Proprietary Information and Inventions Agreement; (b) your delivery to the Company of an effective general release of claims in favor
of the Company and its affiliates in a form acceptable to the Company within 30 days following your termination date. The monthly severance
payments and lump sum bonus payment will be subject to standard deductions and withholdings following termination; provided, however,
that no payments will be made prior to the 40th day following your termination. On the 40th day following your Separation from Service
date, the Company will pay you the salary continuation payments that you would have received on or prior to such date in a lump sum under
the original schedule but for the delay while waiting for the effectiveness of the release, with the balance of the cash severance and
the bonus payment being paid as originally scheduled.
For
purposes of this letter, “Cause” means (A) your conviction (including a guilty plea or a no contest plea) of a felony, or
of any other crime involving fraud, dishonesty or moral turpitude; (B) your commission of or participation in a fraud against the Company;
(C) your material breach of any written agreement between you and the Company (including but not limited to your Proprietary Information
Agreement) or material breach of any statutory or fiduciary duty you owe to the Company, in each case that causes material harm to the
Company; or (D) your conduct that constitutes gross insubordination as reasonably determined by the Board; provided in each case that
the Company gives you written notice and 30 day opportunity to cure and to be heard by the Board before its final determination.
For
purposes of this letter, “Change in Control” means (A) where, as a result of any takeover bid, scheme of arrangement or any
other event or transaction, a person or entity becomes entitled to more than 50% of the Shares or to all or substantially all of the
Group’s business and assets (provided that no sale or transfer undertaken in respect of an internal reorganisation of the structure,
business or assets of the Group shall constitute a Change of Control Event); or (B) any other event determined by the Board to constitute
a “Change of Control Event” for the purposes of these Rules (excluding, for the avoidance of doubt, an internal reorganisation
of the structure, business or assets of the Group).
For
purposes of this letter, you shall have “Good Reason” for your resignation from your employment with the Company and/or
any of its subsidiaries or parent entities or successor entities if any of the following events occur without your consent:(A)
material reduction in your duties (including responsibilities and/or authorities), provided, however, that a change in job position
(including a change in title) shall not be deemed a “material reduction” in and of itself unless your new duties,
responsibilities and/or authorities are substantially reduced from the prior duties, responsibilities and/or authorities; (B)
relocation of your principal place of employment to a place that increases your one-way commute by more than fifty (50) miles as
compared to your then current principal place of employment immediately prior to such relocation; (C) a reduction of at least 10% of
your gross base salary (unless pursuant to a salary reduction program applicable generally to the Company’s executive
employees); or (D) a change in your reporting line such that you report to a position subordinate to the Chief Executive Officer. To
constitute Good Reason, you must (i) give the Company written notice of the existence of the event(s) within ninety (90) days after
their occurrence; (ii) allow the Company thirty (30) days to cure the existence of the event(s); and (iii), if uncured, resign from
your employment within sixty (60) days after the cure period has expired.
For
purposes of this letter, “in Connection with a Change in Control” will mean if your employment is terminated during that
period either three (3) months prior to or twelve (12) months following a Change in Control.
It
is intended that the severance benefits payable under this letter satisfy, to the greatest extent possible, the exemptions from the application
of Internal Revenue Code Section 409A provided under Treasury Regulations 1.409A 1(b)(4), 1.409A 1(b)(5) and 1.409A 1(b)(9), and this
letter will be construed to the greatest extent possible as consistent with those provisions. For purposes of Code Section 409A (including,
without limitation, for purposes of Treasury Regulation Section 1.409A 2(b)(2)(iii)), your right to receive instalment payments under
this letter shall be treated as a right to receive a series of separate payments and, accordingly, each instalment payment hereunder
shall at all times be considered a separate and distinct payment. Notwithstanding any provision to the contrary in this letter, if you
are deemed by the Company at the time of your Separation from Service to be a “specified employee” for purposes of Code Section
409A(a)(2)(B)(i), to the extent delayed commencement of any portion of the severance benefits to which you are entitled under this letter
is required in order to avoid a prohibited distribution under Code Section 409A(a)(2)(B)(i), such portion of your benefits shall not
be provided to you prior to the earlier of (i) the expiration of the six-month period measured from the date of your Separation from
Service with the Company or (ii) the date of your death. Upon the first business day following the expiration of the applicable Code
Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this paragraph shall be paid in a lump sum to you, and any remaining
payments due under this letter shall be paid as otherwise provided herein.
Terms

basis, meaning that either you or the Company may terminate your employment at any time for any reason or no reason.

In
exchange for my becoming employed (or my employment being continued), or retained as a consultant (or my consulting relationship being

“Company”), and for any cash and equity compensation for my services, I hereby agree as follows:
Assignment
of Inventions.
| (a) | Without
further compensation, I hereby agree promptly to disclose to the Company, all Inventions
(as defined below) which I may solely or jointly develop or reduce to practice during the
period of my employment or consulting relationship with the Company which (i) pertain to
any line of business activity of the Company, (ii) are aided by the use of time, material
or facilities of the Company, whether or not during working hours or (iii) relate to any

whether or not during normal working hours (“Company Inventions”). During the
term of my employment or consultancy, all Company Inventions that I conceive, reduce to practice,

Chief Financial Officer
SYDNEY, Australia, June 2, 2026 –
Kazia Therapeutics Limited (NASDAQ: KZIA) (“Kazia,” “Kazia Therapeutics” or the “Company”),
a clinical-stage oncology company advancing therapies designed to reprogram cancer biology and overcome treatment resistance, today announced
the appointment of James Levine as Chief Financial Officer, effective June 1, 2026. Mr. Levine brings more than two decades of experience
across investment banking, executive and financial leadership at publicly traded biotech companies.
“James has built an impressive career leading
financial strategy, strategic transactions and major pharmaceutical collaborations, following an extensive career in investment banking,”
said Dr. John Friend, CEO, Kazia Therapeutics. “As we advance paxalisib and progress our pipeline, James' expertise will be central
to helping us capitalize on that momentum and continue building long-term value for patients and shareholders.”
Most recently, Mr. Levine served as Chief Financial
Officer of Cardiff Oncology, a clinical-stage oncology company developing a PLK1 inhibitor therapy for solid tumors. Prior to Cardiff
Oncology, Mr. Levine served as CFO of Cidara Therapeutics, an antifungal and antiviral biotech company, where he led the financial structuring
of a $568 million licensing collaboration with Mundipharma and a $780 million global partnership with Janssen Pharmaceuticals (Johnson
& Johnson). He also served as CEO of Verenium Corporation, an industrial biotech company, where he executed major asset sales for
total proceeds of approximately $200 million, as well as Sapphire Energy, a human nutrition-focused biotech.
Earlier in his career, Mr. Levine spent 12 years
at Goldman Sachs & Co. as a Managing Director advising pharmaceutical and biotech clients across the U.S. and Europe on financings,
mergers and acquisitions and strategic transactions, including landmark deals such as the Glaxo Wellcome and SmithKline Beecham merger.
Mr. Levine holds a Master of Business Administration degree from The Wharton School at the University of Pennsylvania.
“I am very excited to be joining Kazia as
the Company advances paxalisib across multiple indications and builds out a promising pipeline targeting novel mechanisms of
treatment resistance,” added Mr. Levine. “I look forward to working closely with the management team to help translate
Kazia’s scientific progress into strategic and financial outcomes as we approach what we expect to be a period of meaningful
clinical and strategic milestones for the Company.”
About Kazia Therapeutics
Kazia Therapeutics Limited (NASDAQ: KZIA) is an oncology-focused drug
development company, based in Sydney, Australia. The Company’s lead asset, paxalisib, is an investigational brain penetrant inhibitor
of the PI3K/Akt /mTOR pathway, which is being developed to treat multiple forms of cancer. Licensed from Genentech in late 2016, paxalisib
is or has been the subject of 10 clinical trials. A completed Phase 2/3 study in glioblastoma (GBM-Agile) was reported in 2024, and discussions
are ongoing for designing and executing a pivotal registrational study in pursuit of a standard approval. Other clinical trials involving
paxalisib are ongoing in advanced breast cancer, brain metastases, diffuse midline gliomas, and primary central nervous system lymphoma,
with several of these trials having reported encouraging interim data. Paxalisib was granted Orphan Drug Designation for glioblastoma
by the U.S. Food and Drug Administration (FDA) in February 2018, and Fast Track Designation (FTD) for glioblastoma in August 2020. Paxalisib
was also granted FTD in July 2023 for the treatment of solid tumor brain metastases harboring PI3K pathway mutations in combination with
radiation therapy. Additionally, paxalisib was granted Rare Pediatric Disease Designation and Orphan Drug Designation by the FDA for diffuse
intrinsic pontine glioma in August 2020 and for atypical teratoid / rhabdoid tumors in June 2022 and July 2022, respectively. Kazia is
also developing EVT801, a small molecule inhibitor of VEGFR3, which was licensed from Evotec SE in April 2021. In addition to its clinical-stage
programs, Kazia is advancing NDL2, a potentially first-in-class intracellular PD-L1 protein degrader program targeting a newly identified
mechanism of immunotherapy resistance and metastatic progression, as well as MSETC, a potentially first-in-class SETDB1 inhibitor program
intended to restore immune signaling in tumors that have become resistant to immunotherapy, including checkpoint inhibitors. Both programs
are currently in preclinical development. For more information, please visit www.kaziatherapeutics.com or follow us on X @KaziaTx.
