CONSULTING AGREEMENT 

This CONSULTING AGREEMENT is made and entered into as of June 17, 2021 (the “Effective Date”) by
and between ALIGOS THERAPEUTICS, INC., a Delaware corporation having a principal place of business at 1 Corporate Drive,
2nd Floor, South San Francisco, CA 94080 (“Aligos”) and Kathleen Sereda Glaub, an individual with an address of 1050 Lee Avenue, San Leandro, CA 94577
(“Consultant”). Aligos and the Consultant may be referred to herein individually as “Party” or collectively, as “Parties.” 

1. ENGAGEMENT OF SERVICES. The Parties understand and agree that Consultant will be stepping off
the Board of Director of Aligos effective as of June 17, 2021. However, the Parties desire for Consultant to continue performing certain services for Aligos as a consultant pursuant to this Agreement. As a result, Aligos hereby retains
Consultant, and Consultant hereby agrees to perform services for Aligos that may be mutually agreed upon by Consultant and Aligos from time to time with respect to financing, business development and overall corporate development strategies (the
“Services”). This Agreement and Consultant’s status as a consultant of Aligos providing Services hereunder shall commence on the Effective Date which date coincides with the date of Consultant’s last day as a member of
Aligos’ Board of Director. The terms of this Agreement will govern all Services undertaken by Consultant for Aligos. Subject to the terms and conditions of this Agreement, Consultant will use her best efforts to perform the Services and provide
the results thereof, with the highest degree of professional skill and expertise, by the completion dates requested by Aligos and agreed upon by Consultant. Consultant may not subcontract or otherwise delegate his or her obligations under this
Agreement without Aligos’s prior written consent. 
 2. CONSIDERATION. 

2.1 As consideration for the Services to be peformed by Consultant hereunder, Consultant will continue vesting of any option(s) granted
to Consultant by Aligos to purchase shares of Aligos’s common stock (the “Equity Grants”), which as of the Effective Date, consist of a total of 27,147 shares that have not yet vested under the Equity Grants. All Equity Grants shall
continue to be subject to the terms and conditions set forth in the Aligos Therapeutics, Inc. 2018 Equity Incentive Plan (as amended) or the Aligos Therapeutics, Inc. 2020 Equity Incentive Plan (as amended), as applicable, (both plans collectivetly
referred to herein as the “Equity Plans”). Subject to the terms and conditions of the Equity Plans and the applicable Aligos forms of stock option agreement included with the Equity Grants, for so long as the Consultant continues to
provide continuous services to Aligos hereunder, the options under the Equity Grants will continue to vest pursuant to the vesting schedule provided under the Equity Grants and become exercisable monthly until 100% of the stock options covered by
the Equity Grants are fully vest and excerisable. Without limiting the terms and conditions set forth in the Equity Plans or the Equity Grants, for purposes of clarification, in the event of expiration or early termination of this Agreement and
Consultant’s ceasing to provide continuous services to Aligos, Consultant’s vesting rights under the Equity Grants will be suspended on the effective date of the termination. 

2.2 Consultant shall be reimbursed for any reasonable documented
out-of-pocket expenses actually incurred by Consultant in the performance of the Services hereunder. Consultant shall maintain adequate books and records relating to any
expenses to be reimbursed and shall submit requests for reimbursement, accompanied by a description of activities performed in rendering the Services, on a monthly basis and in a form acceptable to Aligos. All reimbursement shall be sent in a
monthly statement by email to Aligos at ##########@aligos.com, copy to #######@aligos.com.

expenditures by Consultant, Aligos shall reimburse Consultant for travel expenses actually incurred by Consultant in performing the Services, including but not limited to expenses for coach class airfare, ground transportation, lodging and meals,
provided that such expenses are reasonable and necessary as determined by Aligos and approved in writing in advance by Aligos. Aligos shall not compensate Consultant for time spent traveling unless agreed otherwise in writing in advance by the
Parties. 
 2.4 Aligos shall have the right to withhold from Consultant’s payment any taxes, and/or to report payments, as

from Aligos. 
 3. INDEPENDENT CONTRACTOR RELATIONSHIP. Consultant’s relationship with
Aligos shall be that of an independent contractor, and nothing in this Agreement should be construed to create a partnership, joint venture, or employer-employee relationship. Consultant is not the agent of Aligos and is not authorized to make any
representation, contract, or commitment on behalf of Aligos. Consultant will be solely responsible for all tax returns and payments required to be filed with or made to any federal, state or local tax authority with respect to Consultant’s
performance of Services and receipt of compensation under this Agreement.

Consultant further agrees to take all reasonable precautions to prevent any unauthorized disclosure of the Proprietary Information including, but not limited to, ensuring that each
employee, agent or representative of Consultant, if any, with access to any Proprietary Information is legally bound by obligations of non-disclosure and non-use at
least as restrictive as those contained herein, and has been apprised of the duty and obligation to maintain and use Proprietary Information in accordance with the terms and conditions of this Agreement. “Proprietary Information”
means any and all trade secrets, confidential knowledge, know-how, results, data or other proprietary information or materials of Aligos, and all information created or discovered by Consultant in the course
of performing the Services hereunder. The Proprietary Information will remain the sole property of Aligos. Notwithstanding any other provision of this Agreement, the obligations of nondisclosure and non-use
contained in this Agreement shall not apply with respect to any Proprietary Information that has been published or is otherwise readily available to the public other than by a breach of this Agreement. 

4.2 Third-Party Information. Consultant understands that Aligos has received and will in the future receive from third parties
