 1.    PREMISES, BUILDING, PROJECT, AND COMMON AREAS.

 1.1    Premises, Building, Project and Common Areas. 

1.1.1    The Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the premises
set forth in Section 2.2 of the Summary (the “Premises”). The outline of the Premises is set forth in Exhibit A attached hereto. The outline of the
“Building” and the “Project,” as those terms are defined in Section 1.1.2 below, are further depicted on the Site Plan attached hereto as Exhibit
A-1. The parties hereto agree that the lease of the Premises is upon and subject to the terms, covenants and conditions herein set forth, and Tenant covenants as a material part of the consideration
for this Lease to keep and perform each and all of such terms, covenants and conditions by it to be kept and performed and that this Lease is made upon the condition of such performance. The parties hereto hereby acknowledge that the purpose of
Exhibit A is to show the approximate location of the Premises only, and such Exhibit is not meant to constitute an agreement, representation or warranty as to the construction of the Premises, the
precise area thereof or the specific location of the “Common Areas,” as that term is defined in Section 1.1.3, below, or the elements thereof or of the accessways to the Premises or the “Project,” as
that term is defined in Section 1.1.2, below. Except as specifically set forth in this Lease and in the Tenant Work Letter attached hereto as Exhibit B (the “Tenant
Work Letter”), Landlord shall not be obligated to provide or pay for any improvement work or services related to the improvement of the Premises. Tenant also acknowledges that neither Landlord nor any agent of Landlord has made any
representation or warranty regarding the condition of the Premises, the Building or the Project or with respect to the suitability of any of the foregoing for the conduct of Tenant’s business, except as specifically set forth in this Lease and
the Tenant Work Letter. The taking of possession of the Premises by Tenant shall conclusively establish that the Premises and the Building were at such time in good and sanitary order, condition and repair, provided that Landlord shall deliver the
Premises with the roof of the Building to be water-tight and shall cause the plumbing, electrical systems, fire sprinkler system, lighting, air conditioning, heating, and all other building systems serving the Premises in good operating condition
and repair on or before the Lease Commencement Date. Notwithstanding anything in this Lease to the contrary, in connection with the foregoing Landlord shall, at Landlord’s sole cost and expense (which shall not be deemed an “Operating
Expense,” as that term is defined in Section 4.2.4), repair or replace any failed or inoperable portion of the HVAC and other mechanical systems serving the Premises during the first twenty-four (24) months of the
initial Lease Term (“Warranty Period”), provided that the need to repair or replace was not caused by the misuse, misconduct, damage, destruction, omissions, and/or negligence of Tenant, its subtenants and/or assignees, if any, or
any company which is acquired, sold or merged with Tenant (collectively, “Tenant Damage”), or by any modifications, Alterations or improvements constructed by or on behalf of Tenant. Landlord shall coordinate such work with Tenant
and shall utilize commercially reasonable efforts to perform the same in a manner designed to minimize interference with Tenant’s use of the Premises. To the extent repairs which Landlord is required to make pursuant to this
Section 1.1.1 are necessitated in part by Tenant Damage, then Tenant shall reimburse Landlord for an equitable proportion of the cost of such repair. As of the date hereof, Landlord is intending to perform work to the
Building equipment as set forth on Exhibit G at Landlord’s sole cost and expense (and which items shall be repaired at Landlord’s cost during the Warranty Period as set forth above). Landlord
anticipates that such work will be completed prior to March 1, 2019. 
 1.1.2    The Building and The
Project. The Premises constitutes a portion of the building set forth in Section 2.1 of the Summary (the “Building”). The Building is part of an office/laboratory project currently known as
“Gateway Crossing.” The term “Project,” as used in this Lease, shall mean (i) the Building and the Common Areas, (ii) the land (which is improved with landscaping, parking facilities and other improvements) upon
which the Building and the Common Areas are located, (iii) the three (3) other office/laboratory buildings located at Gateway Crossing, and the land upon which such adjacent office/laboratory buildings are located, and (iv) at
Landlord’s discretion, any additional real property, areas, land, buildings or other improvements added thereto outside of the Project. 

1.1.3    Common Areas. Tenant shall have the non-exclusive right to
use in common with other tenants in the Project, and subject to the rules and regulations referred to in Article 5 of this Lease, those portions of the Project which are provided, from time to time, for use in common by Landlord, Tenant and
any other tenants of the Project (such areas, together with such other portions of the Project designated by Landlord, in its discretion, are collectively referred to herein as the “Common Areas”). Landlord shall maintain and
operate the Common Areas in 

  

					
		 	-4-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
a first class manner and the use thereof shall be subject to such rules, regulations and restrictions as Landlord may reasonably make from time to time. Landlord reserves the right to close
temporarily, make alterations or additions to, or change the location of elements of the Project and the Common Areas, provided that such closures, alterations, additions or changes shall not unreasonably interfere with Tenant’s use of such
Common Areas and that Landlord shall use commercially reasonable efforts to minimize any interference with Tenant’s use of and access to the Premises and parking areas in connection therewith. 

1.2    Rentable Square Feet of Premises. The rentable square footage of the Premises and the Building are
hereby deemed to be as set forth in Section 2.2 of the Summary, and shall not be subject to measurement or adjustment during the Lease Term. 

1.3    Early Occupancy Space. Tenant shall have the right to occupy up to 7,154 rentable square feet of the
Premises, as shown on Exhibit A-2 attached hereto (the “Early Occupancy Space”), commencing any time after the full execution of this Lease. Such
Early Occupancy shall be on all of the terms and conditions of this Lease (including, without limitation, the obligation of Tenant to provide insurance as set forth in Section 10.3, below), as if the Rent Commencement Date
had occurred, provided that Tenant shall have no obligation to pay Base Rent with respect to the Early Occupancy Space until the occurrence of the Rent Commencement Date (but Tenant shall pay for utilities and Tenant’s Share of Direct Expenses
attributable to such space during such occupancy). 
 2.    LEASE TERM; OPTION TERM. 

2.1    Lease Term. The terms and provisions of this Lease shall be effective as of the date of this Lease.
The term of this Lease (the “Lease Term”) shall be as set forth in Section 3.1 of the Summary, shall commence on the date set forth in Section 3.2 of the Summary (the
“Lease Commencement Date”), and shall terminate on the date set forth in Section 3.3 of the Summary (the “Lease Expiration Date”) unless this Lease is sooner terminated as hereinafter
provided. For purposes of this Lease, the term “Lease Year” shall mean each consecutive twelve (12) month period during the Lease Term. At any time during the Lease Term, Landlord may deliver to Tenant a notice in the form as
set forth in Exhibit C, attached hereto, as a confirmation only of the information set forth therein, which Tenant shall execute and return to Landlord within five (5) days of receipt thereof. 

2.2    Option Term. 

2.2.1    Option Right. Landlord hereby grants the Tenant originally named in this Lease (the
“Original Tenant”), any “Permitted Transferee” as such term is defined in Section 14.8 below and any assignee of Original Tenant’s entire interest in the Lease that has been approved in
accordance with the terms of Article 14, below (each, a “Permitted Assignee”), one (1) option to extend the Lease Term for a period of eight (8) years (the “Option Term”). Such option to extend
shall be exercisable only by written notice delivered by Tenant to Landlord not more than twelve (12) months nor less than nine (9) months prior to the expiration of the initial Lease Term, stating that Tenant is thereby exercising its
option to lease the Premises during the Option Term. Upon the proper exercise of the option to extend, and provided that, at Landlord’s option, as of the date of delivery of such notice, Tenant is not in default under this Lease, after the
expiration of any applicable notice and cure periods, and has not previously been in default under this Lease after the expiration of any applicable notice and cure periods, more than once in the twelve (12) month period prior to the date of
Tenant’s exercise, and as of the end of the initial Lease Term, Tenant is not in default under this Lease, after the expiration of any applicable notice and cure periods, the Lease Term shall be extended for a period of eight (8) years.
The rights contained in this Section 2.2 shall be personal to Original Tenant and any Permitted Assignee (and not any other assignee, sublessee or “Transferee,” as that term is defined in
Section 14.1, below, of Tenant’s interest in this Lease). In the event that Tenant fails to timely and appropriately exercise its option to extend the Lease Term, in accordance with the terms of this
Section 2.2, then such option shall automatically terminate and shall be of no further force or effect. 

2.2.2    Option Rent. The annual Rent payable by Tenant during the Option Term (the “Option
Rent”) shall be equal to the “Fair Rental Value,” as that term is defined below, for the Premises as of the commencement date of the Option Term. The “Fair Rental Value,” as used in this Lease, shall be equal to
the annual rent per rentable square foot (including additional rent and considering any “base year” or “expense stop” applicable thereto), including all escalations, at which tenants (pursuant to leases consummated within the
twelve (12) month 

  

					
		 	-5-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
period preceding the first day of the Option Term), are leasing non-sublease, non-encumbered, non-equity space which is not significantly greater or smaller in size than the subject space, for a comparable lease term, in an arm’s length transaction, which comparable space is located in the Building or
in “Comparable Buildings,” as that term is defined in this Section 2.2.2, below (transactions satisfying the foregoing criteria shall be known as the “Comparable Transactions”), taking into
consideration the following concessions (the “Concessions”): (a) rental abatement concessions, if any, being granted such tenants in connection with such comparable space; (b) tenant improvements or allowances provided or
to be provided for such comparable space, and taking into account the value, if any, of the existing improvements in the subject space, such value to be based upon the age, condition, design, quality of finishes and layout of the improvements; and
(c) other reasonable monetary concessions being granted such tenants in connection with such comparable space. The Fair Rental Value shall additionally include a determination as to whether, and if so to what extent, Tenant must provide
Landlord with financial security, such as a letter of credit or guaranty, for Tenant’s Rent obligations in connection with Tenant’s lease of the Premises during the Option Term. Such determination shall be made by reviewing the extent of
financial security then generally being imposed in Comparable Transactions from tenants of comparable financial condition and credit history to the then existing financial condition and credit history of Tenant (with appropriate adjustments to
account for differences in the then-existing financial condition of Tenant and such other tenants). The Concessions (A) shall be reflected in the effective rental rate (which effective rental rate shall take into consideration the total dollar
value of such Concessions as amortized on a straight-line basis over the applicable term of the Comparable Transaction (in which case such Concessions evidenced in the effective rental rate shall not be granted to Tenant)) payable by Tenant, or
(B) at Landlord’s election, all such Concessions shall be granted to Tenant in kind. The term “Comparable Buildings” shall mean the Building and those other buildings which are comparable to the Building in terms of age
(based upon the date of completion of construction or major renovation of the building), quality of construction, level of services and amenities, size and appearance, and located in First Class Life Sciences Project in South San Francisco,
California and the surrounding commercial area. 
 2.2.3    Determination of Option Rent. In the event
Tenant timely and appropriately exercises its option to extend the Lease Term, Landlord shall notify Tenant of Landlord’s determination of the Option Rent on or before the date that is thirty (30) days following Landlord’s receipt of
the Option Exercise Notice. If Tenant, on or before the date which is thirty (30) days following the date upon which Tenant receives Landlord’s determination of the Option Rent, fails to accept or object to Landlord’s determination of
Option Rent, Tenant shall be deemed not to have exercised Tenant’s right to extend this Lease pursuant to this Section 2.2, this Section 2.2 shall be of no further force or effect, and the Lease will terminate at
the end of the initial Lease Term. If Tenant, on or before the date which is thirty (30) days following the date upon which Tenant receives Landlord’s determination of the Option Rent, objects to Landlord’s determination of the Option
Rent, then Landlord and Tenant shall attempt to agree upon the Option Rent using their good-faith efforts. If Landlord and Tenant fail to reach agreement within thirty (30) days following Tenant’s objection to the Option Rent (the
“Outside Agreement Date”), then Tenant shall have the right to withdraw its exercise of the option by delivering written notice thereof to Landlord within give (5) business days of the Outside Agreement Date, in which event
Tenant shall be deemed not to have exercised Tenant’s right to extend this Lease pursuant to this Section 2.2, Tenant’s right to extend this Lease pursuant to this Section 2.2 shall be of
no further force or effect, and the Lease will terminate at the end of the initial Lease Term. If Tenant does not so withdraw its exercise of the option, then the option will be deemed to have been irrevocably exercised, and each party shall
thereafter make a separate determination of the Option Rent, within five (5) business days of the Outside Agreement Date, and such determinations shall be submitted to arbitration in accordance with Sections 2.2.3.1
through 2.2.3.8, below. 
 2.2.3.1    Landlord and Tenant shall each appoint one arbitrator who shall be an MAI
appraiser who shall have been active over the five (5) year period ending on the date of such appointment in the leasing or appraisal, as the case may be, of life science properties in South San Francisco, California and the surrounding
commercial area. Each such arbitrator shall be appointed within twenty (20) days after the Outside Agreement Date. Landlord and Tenant may consult with their selected arbitrators prior to appointment and may select an arbitrator who is
favorable to their respective positions. The arbitrators so selected by Landlord and Tenant shall be deemed “Advocate Arbitrators.” 

2.2.3.2    The two (2) Advocate Arbitrators so appointed shall be specifically required pursuant to an engagement
letter within ten (10) days of the date of the appointment of the last appointed Advocate Arbitrator to agree upon and appoint a third arbitrator (“Neutral Arbitrator”) who shall be qualified under the same

  

					
		 	-6-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
criteria set forth hereinabove for qualification of the two Advocate Arbitrators, except that neither the Landlord or Tenant or either parties’ Advocate Arbitrator may, directly or
indirectly, consult with the Neutral Arbitrator prior or subsequent to his or her appointment. The Neutral Arbitrator shall be retained via an engagement letter jointly prepared by Landlord’s counsel and Tenant’s counsel. 

2.2.3.3    The three arbitrators shall, within thirty (30) days of the appointment of the Neutral Arbitrator, reach
a decision as to whether the parties shall use Landlord’s or Tenant’s submitted Option Rent, and shall notify Landlord and Tenant thereof. The determination of the arbitrators shall be limited solely to the issue of whether Landlord’s
or Tenant’s submitted Option Rent is the closest to the actual Option Rent, taking into account the requirements of Section 2.2.2 of this Lease, as determined by the arbitrators. 

2.2.3.4    The decision of the majority of the three arbitrators shall be binding upon Landlord and Tenant. 

2.2.3.5    If either Landlord or Tenant fails to appoint an Advocate Arbitrator within twenty (20) days after the
Outside Agreement Date, then either party may petition the presiding judge of the Superior Court of San Mateo County to appoint such Advocate Arbitrator subject to the criteria in Section 2.2.3.1 of this Lease, or if he or
she refuses to act, either party may petition any judge having jurisdiction over the parties to appoint such Advocate Arbitrator. 

2.2.3.6    If the two (2) Advocate Arbitrators fail to agree upon and appoint the Neutral Arbitrator within ten
(10) business days after the appointment of the last appointed Advocate Arbitrator, then either party may petition the presiding judge of the Superior Court of San Mateo County to appoint the Neutral Arbitrator, subject to criteria in
Section 2.2.3.2 of this Lease, or if he or she refuses to act, either party may petition any judge having jurisdiction over the parties to appoint such arbitrator. 

2.2.3.7    The cost of the arbitration shall be paid by Landlord and Tenant equally. 

2.2.3.8    In the event that the Option Rent shall not have been determined pursuant to the terms hereof prior to the
commencement of the Option Term, Tenant shall be required to pay as Option Rent, an amount equal to 103% of the Base Rent payable by Tenant as of the expiration of the initial Lease Term, and upon the final determination of the Option Rent, the
payments made by Tenant shall be reconciled with the actual amounts of Option Rent due, and the appropriate party shall make any corresponding payment to the other party within thirty (30) days thereafter. 

3.    BASE RENT. Tenant shall pay, without prior notice or demand, to Landlord or
Landlord’s agent at the management office of the Project, or, at Landlord’s option, at such other place as Landlord may from time to time designate in writing, by a check for currency which, at the time of payment, is legal tender for
private or public debts in the United States of America, base rent (“Base Rent”) as set forth in Section 4 of the Summary, payable in equal monthly installments as set forth in
Section 4 of the Summary in advance on or before the first day of each and every calendar month during the Lease Term, commencing on the Rent Commencement Date, without any setoff or deduction whatsoever. The Base Rent for
the first full month of the Lease Term shall be paid at the time of the parties’ mutual execution and delivery of this Lease. If any Rent payment date (including the Rent Commencement Date) falls on a day of the month other than the first day
of such month or if any payment of Rent is for a period which is shorter than one month, the Rent for any fractional month shall accrue on a daily basis for the period from the date such payment is due to the end of such calendar month or to the end
of the Lease Term at a rate per day which is equal to 1/365 of the applicable annual Rent. All other payments or adjustments required to be made under the terms of this Lease that require proration on a time basis shall be prorated on the same
basis. 
 4.    ADDITIONAL RENT. 

4.1    General Terms. 

4.1.1    Direct Expenses; Additional Rent. In addition to paying the Base Rent specified in Article 3
of this Lease, Tenant shall pay “Tenant’s Share” of the annual “Direct Expenses,” as those terms are defined 

  

					
		 	-7-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
in Sections 4.2.6 and 4.2.2 of this Lease, respectively, allocable to the Building. Such payments by Tenant, together with any and all other amounts payable by Tenant to Landlord pursuant
to the terms of this Lease, are hereinafter collectively referred to as the “Additional Rent”, and the Base Rent and the Additional Rent are herein collectively referred to as “Rent.” All amounts due under this
Article 4 as Additional Rent shall be payable for the same periods and in the same manner as the Base Rent. Without limitation on other obligations of Tenant which survive the expiration of the Lease Term, the obligations of Tenant to pay the
Additional Rent provided for in this Article 4 shall survive the expiration of the Lease Term. 

4.1.2    Triple Net Lease. Landlord and Tenant acknowledge that, except as otherwise provided to the
contrary in this Lease, it is their intent and agreement that this Lease be a “TRIPLE NET” lease and that as such, the provisions contained in this Lease are intended to pass on to Tenant or reimburse Landlord for the costs
and expenses reasonably associated with this Lease, the Building and the Project, and Tenant’s operation therefrom. To the extent such costs and expenses payable by Tenant cannot be charged directly to, and paid by, Tenant, such costs and
expenses shall be paid by Landlord but reimbursed by Tenant as Additional Rent. 
 4.2    Definitions of Key Terms

4.2.2    “Direct Expenses” shall mean “Operating Expenses” and “Tax
Expenses.” 
 4.2.3    “Expense Year” shall mean each calendar year in which any portion of
the Lease Term falls, through and including the calendar year in which the Lease Term expires, provided that Landlord, upon notice to Tenant, may change the Expense Year from time to time to any other twelve (12) consecutive month period, and,
in the event of any such change, Tenant’s Share of Direct Expenses shall be equitably adjusted for any Expense Year involved in any such change. 

4.2.4    “Operating Expenses” shall mean all expenses, costs and amounts of every kind and nature which
Landlord pays or accrues during any Expense Year because of or in connection with the ownership, management, maintenance, security, repair, replacement, restoration or operation of the Project, or any portion thereof. Without limiting the generality
of the foregoing, Operating Expenses shall specifically include any and all of the following: (i) the cost of supplying all utilities (to the extent not separately metered and paid directly by Tenant or another tenant or occupant), the cost of
operating, repairing, maintaining, and renovating the utility, telephone, mechanical, sanitary, storm drainage, and elevator systems, and the cost of maintenance and service contracts in connection therewith; (ii) the cost of licenses,

occupants, (B) that are required to comply with present or anticipated conservation programs, (C) which are replacements or modifications of nonstructural items located in the Common

4.2.5    Taxes. 

4.2.5.1    “Tax Expenses” shall mean all federal, state, county, or local governmental or municipal
taxes, fees, charges or other impositions of every kind and nature, whether general, special, ordinary or extraordinary (including, without limitation, real estate taxes, general and special assessments, transit taxes, leasehold taxes or taxes based
upon the receipt of rent, including gross receipts or sales taxes applicable to the receipt of rent, unless required to be paid by Tenant, personal property taxes imposed upon the fixtures, machinery, equipment, apparatus, systems and equipment,
appurtenances, furniture and other personal property used in connection with the Project, or any portion thereof), which Landlord shall pay or accrue during any Expense Year (without regard to any different fiscal year used by such governmental or
municipal authority) because of or in connection with the ownership, leasing and operation of the Project, or any portion thereof. 

4.2.5.2    Tax Expenses shall include, without limitation: (i) Any tax on the rent, right to rent or other income
from the Project, or any portion thereof, or as against the business of leasing the Project, or any portion thereof; (ii) Any assessment, tax, fee, levy or charge in addition to, or in substitution, partially or totally, of any assessment, tax,

		 	-10-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
occupancy by Tenant of the Premises, or any portion thereof; and (iv) Any assessment, tax, fee, levy or charge, upon this transaction or any document to which Tenant is a party, creating or
transferring an interest or an estate in the Premises or the improvements thereon. 
 4.2.5.3    Any reasonable costs
and expenses (including, without limitation, reasonable attorneys’ and consultants’ fees) incurred in attempting to protest, reduce or minimize Tax Expenses shall be included in Tax Expenses in the Expense Year such expenses are incurred.
Tax refunds shall be credited against Tax Expenses and refunded to Tenant regardless of when received, based on the Expense Year to which the refund is applicable, provided that in no event shall the amount to be refunded to Tenant for any such
Expense Year exceed the total amount paid by Tenant as Additional Rent under this Article 4 for such Expense Year. If Tax Expenses for any period during the Lease Term or any extension thereof are increased after payment thereof for any
reason, including, without limitation, error or reassessment by applicable governmental or municipal authorities, Tenant shall pay Landlord upon demand Tenant’s Share of any such increased Tax Expenses. Notwithstanding anything to the contrary
contained in this Section 4.2.5, there shall be excluded from Tax Expenses (i) all excess profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes, federal and
state income taxes, and other taxes to the extent applicable to Landlord’s net income (as opposed to rents, receipts or income attributable to operations at the Project), (ii) any items included as Operating Expenses, (iii) any items paid
by Tenant under Section 4.5 of this Lease, (iv) any assessment amounts greater than the amount which would be payable if such assessment were paid in installments over the longest permitted period; (v) tax
increases due to improvements built for the sole use of other tenants; and (vi) penalties or interest thereon due to Landlord’s late or non-payment of Taxes.. 

4.2.6    “Tenant’s Share” shall mean the percentage set forth in Section 6
of the Summary. 
 4.3    Allocation of Direct Expenses. The parties acknowledge that the Building is a
part of a multi-building project and that the costs and expenses incurred in connection with the Project (i.e., the Direct Expenses) should be shared between the Building and the other buildings in the Project. Accordingly, as set forth in
Section 4.2 above, Direct Expenses (which consist of Operating Expenses and tax Expenses) are determined annually for the Project as a whole, and a portion of the Direct Expenses, which portion shall be determined by
Landlord on an equitable basis, shall be allocated to the Building (as opposed to other buildings in the Project). Such portion of Direct Expenses allocated to the Building shall include all Direct Expenses attributable solely to the Building and an
equitable portion of the Direct Expenses attributable to the Project as a whole, and shall not include Direct Expenses attributable solely to other buildings in the Project. 

4.4    Calculation and Payment of Additional Rent. Commencing on the Rent Commencement Date, Tenant shall
pay to Landlord, in the manner set forth in Section 4.4.1, below, and as Additional Rent, Tenant’s Share of Direct Expenses for each Expense Year. 

4.4.1    Statement of Actual Direct Expenses and Payment by Tenant. Landlord shall give to Tenant within six
(6) months following the end of each Expense Year, a statement (the “Statement”) which shall state the Direct Expenses incurred or accrued for such preceding Expense Year, and which shall indicate the amount of Tenant’s
Share of Direct Expenses. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, Tenant shall pay, with its next installment of Base Rent due at least thirty (30) days thereafter, the full amount of
Tenant’s Share of Direct Expenses for such Expense Year, less the amounts, if any, paid during such Expense Year as “Estimated Direct Expenses,” as that term is defined in Section 4.4.2, below, and if
Tenant paid more as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses, Tenant shall receive a credit in the amount of Tenant’s overpayment against Rent next due under this Lease. The failure of Landlord to timely
furnish the Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing its rights under this Article 4. Even though the Lease Term has expired and Tenant has vacated the Premises, when the final determination is made
of Tenant’s Share of Direct Expenses for the Expense Year in which this Lease terminates, Tenant shall pay to Landlord such amount within thirty (30) days, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant’s
Share of Direct Expenses, Landlord shall, within thirty (30) days, deliver a check payable to Tenant in the amount of the overpayment. The provisions of this Section 4.4.1 shall survive the expiration or earlier
termination of the Lease Term.

[Aligos Thereapeutics, Inc.]

 4.4.2    Statement of Estimated Direct Expenses. In
addition, Landlord shall give to Tenant within six (6) months following the end of each Expense Year a yearly expense estimate statement (the “Estimate Statement”) which shall set forth Landlord’s reasonable estimate (the
“Estimate”) of what the total amount of Direct Expenses for the then-current Expense Year shall be and the estimated Tenant’s Share of Direct Expenses (the “Estimated Direct Expenses”). The failure of Landlord
to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Estimated Direct Expenses under this Article 4, nor shall Landlord be prohibited from revising any Estimate
Statement or Estimated Direct Expenses theretofore delivered to the extent necessary. Thereafter, Tenant shall pay, with its next installment of Base Rent due at least thirty (30) days thereafter, a fraction of the Estimated Direct Expenses for
the then-current Expense Year (reduced by any amounts paid pursuant to the last sentence of this Section 4.4.2). Such fraction shall have as its numerator the number of months which have elapsed in such current Expense
Year, including the month of such payment, and twelve (12) as its denominator. Until a new Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time), Tenant shall pay monthly, with the monthly Base
Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Direct Expenses set forth in the previous Estimate Statement delivered by Landlord to Tenant. 

4.5    Taxes and Other Charges for Which Tenant Is Directly Responsible. Tenant shall be liable for and
shall pay ten (10) days before delinquency, taxes levied against Tenant’s equipment, furniture, fixtures and any other personal property located in or about the Premises. If any such taxes on Tenant’s equipment, furniture, fixtures
and any other personal property are levied against Landlord or Landlord’s property or if the assessed value of Landlord’s property is increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or any
other personal property and if Landlord pays the taxes based upon such increased assessment, which Landlord shall have the right to do regardless of the validity thereof but only under proper protest if requested by Tenant, Tenant shall upon demand
repay to Landlord the taxes so levied against Landlord or the proportion of such taxes resulting from such increase in the assessment, as the case may be. 

4.6    Landlord’s Books and Records. Within one hundred eighty (180) days after receipt by Tenant
of a Statement, if Tenant disputes the amount of Additional Rent set forth in the Statement, a member of Tenant’s finance department, or an independent certified public accountant (which accountant is a member of a nationally recognized
accounting firm and is not working on a contingency fee basis) (“Tenant’s Accountant”), designated and paid for by Tenant, may, after reasonable notice to Landlord and at reasonable times, inspect Landlord’s records with
respect to the Statement at Landlord’s offices, provided that there is no existing Event of Default and Tenant has paid all amounts required to be paid under the applicable Estimate Statement and Statement, as the case may be. In connection
with such inspection, Tenant and Tenant’s agents must agree in advance to follow Landlord’s reasonable rules and procedures regarding inspections of Landlord’s records, and shall execute a commercially reasonable confidentiality
agreement regarding such inspection. Tenant’s failure to dispute the amount of Additional Rent set forth in any Statement within one hundred eighty (180) days of Tenant’s receipt of such Statement shall be deemed to be Tenant’s
approval of such Statement and Tenant, thereafter, waives the right or ability to dispute the amounts set forth in such Statement. If after such inspection, Tenant still disputes such Additional Rent, a determination as to the proper amount shall be
made, at Tenant’s expense, by an independent certified public accountant (the “Accountant”) selected by Landlord and subject to Tenant’s reasonable approval; provided that if such Accountant determines that Direct Expenses
were overstated by more than five percent (5%), then the cost of the Accountant and the cost of such determination shall be paid for by Landlord, and Landlord shall reimburse Tenant for the cost of Tenant’s Accountant (provided that such cost
shall be a reasonable market cost for such services). 
 5.    USE OF PREMISES. 

5.1    Permitted Use. Tenant shall use the Premises solely for the Permitted Use set forth in
Section 7 of the Summary and Tenant shall not use or permit the Premises or the Project to be used for any other purpose or purposes whatsoever without the prior written consent of Landlord, which may be withheld in
Landlord’s sole discretion. 
 5.2    Prohibited Uses. Tenant further covenants and agrees that
Tenant shall not use, or suffer or permit any person or persons to use, the Premises or any part thereof for any use or purpose in violation of the laws of the United States of America, the State of California, or the ordinances, regulations or
requirements of the local municipal

hazardous materials or substances, as those terms are defined by applicable laws now or hereafter in effect, or any Underlying Documents which Landlord has delivered to Tenant. Landlord shall have the right to impose reasonable and customary rule
and regulations regarding the use of the Project, as reasonably deemed necessary by Landlord with respect to the orderly operation of the Project, and Tenant shall comply with such reasonable rules and regulations. Tenant shall not do or permit
anything to be done in or about the Premises which will in any way damage the reputation of the Project or obstruct or interfere with the rights of other tenants or occupants of the Building, or injure or annoy them or use or allow the Premises to
be used for any unlawful purpose, nor shall Tenant cause, maintain or permit any nuisance in, on or about the Premises. Tenant shall comply with, and Tenant’s rights and obligations under the Lease and Tenant’s use of the Premises shall be

5.3.1.1    Prohibitions. As a material inducement to Landlord to enter into this Lease with Tenant, Tenant
has fully and accurately completed Landlord’s Pre-Leasing Environmental Exposure Questionnaire (the “Environmental Questionnaire”), which is attached as Exhibit F. Tenant
agrees that except for those chemicals or materials, and their respective quantities, specifically listed on the Environmental Questionnaire, neither Tenant nor Tenant’s employees, contractors and subcontractors of any tier, entities with a
contractual relationship with Tenant (other than Landlord), or any entity acting as an agent or sub-agent of Tenant (collectively, “Tenant’s Agents”) will produce, use, store or generate
any “Hazardous Materials,” as that term is defined below, on, under or about the Premises, nor cause or permit any Hazardous Material to be brought upon, placed, stored, manufactured, generated, blended, handled, recycled, used or
“Released,” as that term is defined below, on, in, under or about the Premises. If any information provided to Landlord by Tenant on the Environmental Questionnaire, or otherwise relating to information concerning Hazardous Materials is
intentionally or recklessly false, incomplete, or misleading in any material respect, the same shall be deemed a default by Tenant under this Lease. Tenant shall deliver to Landlord an updated Environmental Questionnaire at least once a year. Any
Hazardous Materials use for the Premises not described on the initial Environmental Questionnaire shall be subject to all terms and conditions of this Lease. Tenant shall not install or permit any underground storage tank on the Premises. For

mixture, solution, substance, object, waste or any combination thereof, which is or may be hazardous to human health, safety or to the environment due to its radioactivity, ignitability, corrosiveness, reactivity, explosiveness, toxicity,
carcinogenicity, infectiousness or other harmful or potentially harmful properties or effects, or defined as, regulated as or included in, the definition of “hazardous substances,” “hazardous wastes,” “hazardous
materials,” or “toxic substances” under any Environmental Laws. The term “Hazardous Materials” for purposes of this Lease shall also include any mold, fungus or spores, whether or not the same is defined, listed, or
otherwise classified as a “hazardous material” under any Environmental Laws, if such mold, fungus or spores may pose a risk to human health or the environment or negatively impact the value of the Premises. For purposes of this Lease,
“Release” or “Released” or “Releases” shall mean any release, deposit, discharge, emission, leaking, spilling, seeping, migrating, injecting, pumping, pouring, emptying, escaping, dumping,
disposing, or other movement of Hazardous Materials into the environment. Landlord acknowledges that Tenant will be installing and using fume hoods in the Premises and that emissions of Hazardous Materials into the air in compliance with
Environmental Laws shall not be considered Releases. 
 5.3.1.2    Notices to Landlord. Tenant shall
notify Landlord in writing as soon as possible but in no event later than five (5) days after (i) the occurrence of any actual, alleged or threatened Release of any Hazardous Material in, on, under, from, about or in the vicinity of the
Premises (whether past or present), regardless of the source or quantity of any such Release, or (ii) Tenant becomes aware of any regulatory actions, inquiries, inspections, investigations, directives, or any cleanup, compliance, enforcement or

damage, contribution, cost recovery, compensation, loss or injury. Collectively, the matters set forth in clauses (i), (ii) and (iii) above are hereinafter referred to as “Hazardous Materials Claims”. Tenant shall promptly
forward to Landlord copies of all orders, notices, permits, applications and other communications and reports in connection with any Hazardous Materials Claims. Additionally, Tenant shall promptly advise Landlord in writing of Tenant’s
discovery of any occurrence or condition on, in, under or about the Premises that could subject Tenant or Landlord to any liability, or restrictions on ownership, occupancy, transferability or use of the Premises under any “Environmental

Tenant’s intention to do so and affording Landlord the opportunity to join and participate, as a party if Landlord so elects, in such proceedings and in no event shall Tenant enter into any agreements which are binding on Landlord or the

Clean-up prior to surrender of the Premises upon the expiration or earlier termination of this Lease. Tenant shall obtain and deliver to Landlord a letter or other written determination from the overseeing

Tenant’s consultants, attorneys, property managers and employees that have a need to know such information), including any governmental authority, without the prior written consent of Landlord. In the event Tenant reasonably believes that
disclosure is compelled by applicable law or order of any court or other governmental agency, it shall provide Landlord ten (10) days’ advance notice of disclosure of confidential information so that Landlord may attempt to obtain a
protective order. Tenant may additionally release such information to bona fide prospective investors, business and merger partners, purchasers, lenders, assignees and subtenants, subject to any such parties’ written agreement to be bound by
the terms of this Section 5.3.

Landlord may not require Tenant to remove at the expiration or early termination of the Lease Term any Tenant Improvements shown in the approved Landlord’s Final Working Drawings or any Alterations consistent with the improvements shown in the
approved Landlord’s Final Working Drawings or any Alternations which are otherwise consistent with the typical tenant improvements in the biotechnology or pharmaceutical industries. If Tenant fails to complete such removal and/or to repair any

Landlord and any mortgagee of Landlord (unless such cancellation is the result of non-payment of premiums). Tenant shall deliver certificates of said policy or policies to Landlord on or before the Lease
Commencement Date and at least five (5) days before the expiration dates thereof. In the event Tenant shall fail to procure such insurance, or to deliver such policies or certificate, Landlord may, at its option, procure such policies for the
account of Tenant, and the cost thereof shall be paid to Landlord within five (5) days after delivery to Tenant of bills therefor. 

10.5    Subrogation. Landlord and Tenant hereby agree to look solely to, and seek recovery only from, their
respective insurance carriers in the event of a property or business interruption loss to the extent that such coverage is agreed to be provided hereunder. The parties each hereby waive all rights and claims against each other for such losses, and
waive all rights of subrogation of their respective insurers. The parties agree that their respective insurance policies do now, or shall, contain the waiver of subrogation. 

10.6    Additional Insurance Obligations. Tenant shall carry and maintain during the entire Lease Term, at
Tenant’s sole cost and expense, increased amounts of the insurance required to be carried by Tenant pursuant to this Article 10 and such other reasonable types of insurance coverage and in such reasonable amounts covering the Premises
and Tenant’s operations therein, as may be reasonably requested by Landlord or Landlord’s lender, but in no event in excess of the amounts and types of insurance then being required by landlords of buildings comparable to and in the
vicinity of the Building. 
 11.    DAMAGE AND DESTRUCTION. 

11.1    Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the
Premises resulting from fire or any other casualty. If the Premises or any Common Areas serving or providing access to the Premises shall be damaged by fire or other casualty, Landlord shall notify Tenant within sixty (60) days after the date
of discovery of the damage whether or not Landlord will restore the Premises and Common Areas and, in Landlord’s reasonable judgment, the time period within which the restoration can be completed. If Landlord elects to restore the Premises and
Common Areas (the “Landlord Repair Notice”), Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of
this Article 11, restore the Base Building and such Common Areas. Such restoration shall be to substantially the same condition of the Base Building and the Common Areas prior to the casualty, except for modifications required by zoning and
building codes and other laws or by the holder of a mortgage on the Building or Project or any other modifications to the Common Areas deemed desirable by Landlord, which are consistent with the character of the Project, provided that access to the
Premises shall not be materially impaired. If Landlord elects to restore the Premises and Common Areas, Tenant shall assign to Landlord (or to any party designated 

  

					
		 	-23-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under Section 10.3 of this Lease, and Landlord shall repair any injury or
damage to the Tenant Improvements and the Original Improvements installed in the Premises and shall return such Tenant Improvements and Original Improvements to their original condition; provided that if the cost of such repair by Landlord exceeds
the amount of insurance proceeds received by Landlord from Tenant’s insurance carrier (including by taking into account any deductible or self-insured retention), as assigned by Tenant, the cost of such repairs shall be paid by Tenant to
Landlord prior to Landlord’s commencement of repair of the damage. In the event that Landlord does not deliver the Landlord Repair Notice within sixty (60) days following the date the casualty becomes known to Landlord, Tenant shall, at
its sole cost and expense, repair any injury or damage to the Tenant Improvements and the Original Improvements installed in the Premises and shall return such Tenant Improvements and Original Improvements to their original condition. Whether or not
Landlord delivers a Landlord Repair Notice, prior to the commencement of construction, Tenant shall submit to Landlord, for Landlord’s review and approval, all plans, specifications and working drawings relating thereto, and Landlord shall
select the contractors to perform such improvement work. Tenant shall in addition cooperate with requests for information regarding any repairs from Landlord’s insurer(s) by providing the requested information within ten (10) days after
Tenant receives the request. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business resulting in any way from such damage or the repair thereof; provided however, that if such
fire or other casualty shall have damaged the Premises or Common Areas necessary to Tenant’s occupancy, and the damaged portion of the Premises are not occupied by Tenant as a result thereof, then during the time and to the extent the Premises
are unfit for occupancy, the Rent shall be abated in proportion to the ratio that the amount of rentable square feet of the Premises which is unfit for occupancy for the purposes permitted under this Lease bears to the total rentable square feet of
the Premises. In the event that Landlord shall not deliver the Landlord Repair Notice, Tenant’s right to rent abatement pursuant to the preceding sentence shall terminate as of the date which is reasonably determined by Landlord to be the date
Tenant should have completed repairs to the Premises assuming Tenant used reasonable due diligence in connection therewith. 

11.2    Landlord’s Option to Repair. Notwithstanding the terms of
Section 11.1 of this Lease, Landlord may elect not to rebuild and/or restore the Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing of such termination within sixty
(60) days after the date of discovery of the damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect only if the Building or Project shall be damaged by fire or
other casualty or cause, whether or not the Premises are affected, and one or more of the following conditions is present: (i) in Landlord’s reasonable judgment, repairs cannot reasonably be completed within one (1) year after the
date of discovery of the damage (when such repairs are made without the payment of overtime or other premiums); (ii) the holder of any mortgage on the Building or Project or ground lessor with respect to the Building or Project shall require that
the insurance proceeds or any portion thereof be used to retire the mortgage debt, or shall terminate the ground lease, as the case may be; (iii) more than $1,000,000.00 of damage is not covered by Landlord’s insurance policies, and Tenant
does not agree to pay any such uninsured costs in excess of such $1,000,000.00; (iv) Landlord decides to rebuild the Building or Common Areas so that they will be substantially different structurally or architecturally; (v) the damage occurs
during the last twelve (12) months of the Lease Term; or (vi) any owner of any other portion of the Project, other than Landlord, does not intend to repair the damage to such portion of the Project. 

11.3    Tenant’s Option to Terminate. Notwithstanding anything to the contrary in Sections 11.1
or 11.2, if (a) the damage occurs during the last twelve (12) months of the Lease Term, or (b) in the reasonable judgment of Landlord, the repairs cannot be completed within eight (8) months after the date of discovery of
the damage (or are not in fact completed within nine (9) months after the date of discovery of the damage), Tenant may elect, no earlier than sixty (60) days after the date of the damage and not later than ninety (90) days after the
date of such damage, or within thirty (30) days after such repairs are not timely completed, to terminate this Lease by written notice to Landlord effective as of the date specified in the notice, which date shall not be less than thirty
(30) days nor more than sixty (60) days after the date such notice is given by Tenant;, provided that the damage to the Project by fire or other casualty was not caused by the gross negligence or intentional act of Tenant or its partners
or subpartners and their respective officers, agents, servants, employees, and independent contractors. 

11.4    Waiver of Statutory Provisions. The provisions of this Lease, including this Article 11,
constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building or the Project, and any statute or regulation of the State of California,
including, 

  

					
		 	-24-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement
between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the Project. 

12.    NONWAIVER. No provision of this Lease shall be deemed waived by either party hereto
unless expressly waived in a writing signed thereby. The waiver by either party hereto of any breach of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach of same or any other term, covenant
or condition herein contained. The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the
particular Rent so accepted, regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such Rent. No acceptance of a lesser amount than the Rent herein stipulated shall be deemed a waiver of Landlord’s right
to receive the full amount due, nor shall any endorsement or statement on any check or payment or any letter accompanying such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord’s right to recover the full amount due. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Lease Term or of Tenant’s right of possession hereunder, or after
the giving of any notice shall reinstate, continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a suit, or after final
judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment. 

13.    CONDEMNATION. If the whole or any part of the Premises, Building or Project shall be
taken by power of eminent domain or condemned by any competent authority for any public or quasi-public use or purpose, or if any adjacent property or street shall be so taken or condemned, or reconfigured or vacated by such authority in such manner
as to require the use, reconstruction or remodeling of any part of the Premises, Building or Project, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to
terminate this Lease effective as of the date possession is required to be surrendered to the authority. Tenant shall not because of such taking assert any claim against Landlord or the authority for any compensation because of such taking and
Landlord shall be entitled to the entire award or payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and fixtures belonging to
Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the terms of this Lease, for the unamortized value of an improvements paid for by Tenant and for moving expenses, so long as such claims do not diminish the award available
to Landlord, its ground lessor with respect to the Building or Project or its mortgagee, and such claim is payable separately to Tenant. All Rent shall be apportioned as of the date of such termination. If any part of the Premises shall be taken,
and this Lease shall not be so terminated, the Rent shall be proportionately abated. Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of The California Code of Civil Procedure. Notwithstanding
anything to the contrary contained in this Article 13, in the event of a temporary taking of all or any portion of the Premises for a period of one hundred and eighty (180) days or less, then this Lease shall not terminate but the Base
Rent and the Additional Rent shall be abated for the period of such taking in proportion to the ratio that the amount of rentable square feet of the Premises taken bears to the total rentable square feet of the Premises. Landlord shall be entitled
to receive the entire award made in connection with any such temporary taking. 
 14.    ASSIGNMENT AND
SUBLETTING. 
 14.1    Transfers. Tenant shall not, without the prior written consent of Landlord,
assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law,
sublet the Premises or any part thereof, or enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons other than Tenant and its employees and contractors (all of the
foregoing are hereinafter sometimes referred to collectively as “Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “Transferee”). If Tenant desires
Landlord’s consent to any Transfer, Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of the Transfer, which shall not be less than thirty
(30) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to 

  

					
		 	-25-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
be transferred (the “Subject Space”), (iii) all of the terms of the proposed Transfer and the consideration therefor, including calculation of the “Transfer
Premium”, as that term is defined in Section 14.3 below, in connection with such Transfer, the name and address of the proposed Transferee, and a copy of all existing executed and/or proposed documentation
pertaining to the proposed Transfer, and (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, business credit and personal references and history of the proposed Transferee and any
other information reasonably required by Landlord which will enable Landlord to determine the financial responsibility, character, and reputation of the proposed Transferee, nature of such Transferee’s business and proposed use of the Subject
Space. Any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option, constitute a default by Tenant under this Lease. Whether or not Landlord
consents to any proposed Transfer, Tenant shall pay Landlord’s reasonable review and processing fees, as well as any reasonable professional fees (including, without limitation, attorneys’, accountants’, architects’,
engineers’ and consultants’ fees) incurred by Landlord, within thirty (30) days after written request by Landlord. 

14.2    Landlord’s Consent. Landlord shall not unreasonably withhold or delay its consent to any
proposed Transfer of the Subject Space to the Transferee on the terms specified in the Transfer Notice. Without limitation as to other reasonable grounds for withholding consent, the parties hereby agree that it shall be reasonable under this Lease
and under any applicable law for Landlord to withhold consent to any proposed Transfer where one or more of the following apply: 

14.2.1    The Transferee is of a character or reputation or engaged in a business which is not consistent with the quality
of the Building or the Project; 
 14.2.2    The Transferee is either a governmental agency or instrumentality thereof;

 14.2.3    The Transferee is not a party of reasonable financial worth and/or financial stability in light of the
responsibilities to be undertaken in connection with the Transfer on the date consent is requested; or 
 14.2.4    The
proposed Transfer would cause a violation of another lease for space in the Project, or would give an occupant of the Project a right to cancel its lease. 

If Landlord consents to any Transfer pursuant to the terms of this Section 14.2 (and does not exercise any recapture
rights Landlord may have under Section 14.4 of this Lease), Tenant may within six (6) months after Landlord’s consent, but not later than the expiration of said six-month
period, enter into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to Section 14.1 of this
Lease, provided that if there are any changes in the terms and conditions from those specified in the Transfer Notice such that Landlord would initially have been entitled to refuse its consent to such Transfer under this
Section 14.2, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord’s right of recapture, if any, under
Section 14.4 of this Lease). Notwithstanding anything to the contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord has unreasonably withheld or delayed its consent under
Section 14.2 or otherwise has breached or acted unreasonably under this Article 14, their sole remedies shall be a suit for contract damages (other than damages for injury to, or interference with, Tenant’s
business including, without limitation, loss of profits, however occurring) or declaratory judgment and an injunction for the relief sought, and Tenant hereby waives all other remedies, including, without limitation, any right at law or equity to
terminate this Lease, on its own behalf and, to the extent permitted under all applicable laws, on behalf of the proposed Transferee. 

14.3    Transfer Premium. If Landlord consents to a Transfer, as a condition thereto which the parties
hereby agree is reasonable, Tenant shall pay to Landlord fifty percent (50%) of any “Transfer Premium,” as that term is defined in this Section 14.3, received by Tenant from such Transferee.
“Transfer Premium” shall mean all rent, additional rent or other consideration payable by such Transferee in connection with the Transfer in excess of the Rent and Additional Rent payable by Tenant under this Lease during the term
of the Transfer on a per rentable square foot basis if less than all of the Premises is transferred, and after deduction of (i) any costs of improvements made to the Subject Space in connection with such Transfer, (ii) brokerage
commissions paid in connection with such Transfer, and (iii) reasonable legal fees incurred in connection with such Transfer, in each case amortized over the 

  

					
		 	-26-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
remaining Term of this Lease. “Transfer Premium” shall also include, but not be limited to, key money, bonus money or other cash consideration paid by Transferee to Tenant in
connection with such Transfer, and any payment in excess of fair market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee in connection with such
Transfer. The determination of the amount of Landlord’s applicable share of the Transfer Premium shall be made on a monthly basis as rent or other consideration is received by Tenant under the Transfer. 

14.4    Landlord’s Option as to Subject Space. Notwithstanding anything to the contrary contained in
this Article 14, in the event Tenant contemplates a Transfer which, together with all prior Transfers then remaining in effect, would cause fifty percent (50%) or more of the Premises to be Transferred for more than twenty five percent
(25%) of the then remaining Lease Term (taking into account any extension of the Lease Term which has irrevocably exercised by Tenant), Tenant shall give Landlord notice (the “Intention to Transfer Notice”) of such contemplated
Transfer (whether or not the contemplated Transferee or the terms of such contemplated Transfer have been determined). The Intention to Transfer Notice shall specify the portion of and amount of rentable square feet of the Premises which Tenant
intends to Transfer (the “Contemplated Transfer Space”), the contemplated date of commencement of the Contemplated Transfer (the “Contemplated Effective Date”), and the contemplated length of the term of such
contemplated Transfer, and shall specify that such Intention to Transfer Notice is delivered to Landlord pursuant to this Section 14.4 in order to allow Landlord to elect to recapture the Contemplated Transfer Space.
Thereafter, Landlord shall have the option, by giving written notice to Tenant within thirty (30) days after receipt of any Intention to Transfer Notice, to recapture the Contemplated Transfer Space. Such recapture shall cancel and terminate
this Lease with respect to such Contemplated Transfer Space as of the Contemplated Effective Date. In the event of a recapture by Landlord, if this Lease shall be canceled with respect to less than the entire Premises, the Rent reserved herein shall
be prorated on the basis of the number of rentable square feet retained by Tenant in proportion to the number of rentable square feet contained in the Premises, and this Lease as so amended shall continue thereafter in full force and effect, and
upon request of either party, the parties shall execute written confirmation of the same. If Landlord declines, or fails to elect in a timely manner, to recapture such Contemplated Transfer Space under this Section 14.4,
then, subject to the other terms of this Article 14, for a period of nine (9) months (the “Nine Month Period”) commencing on the last day of such thirty (30) day period, Landlord shall not have any right to
recapture the Contemplated Transfer Space with respect to any Transfer made during the Nine Month Period, provided that any such Transfer is substantially on the terms set forth in the Intention to Transfer Notice, and provided further that any such
Transfer shall be subject to the remaining terms of this Article 14. If such a Transfer is not so consummated within the Nine Month Period (or if a Transfer is so consummated, then upon the expiration of the term of any Transfer of such
Contemplated Transfer Space consummated within such Nine Month Period), Tenant shall again be required to submit a new Intention to Transfer Notice to Landlord with respect any contemplated Transfer, as provided above in this
Section 14.4. 
 14.5    Effect of Transfer. If Landlord consents to a Transfer,
(i) the terms and conditions of this Lease shall in no way be deemed to have been waived or modified, (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver
to Landlord, promptly after execution, an original executed copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord, (iv) Tenant shall furnish upon Landlord’s request a complete statement, certified
by an independent certified public accountant, or Tenant’s chief financial officer, setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from such Transfer, and (v) no Transfer relating to
this Lease or agreement entered into with respect thereto, whether with or without Landlord’s consent, shall relieve Tenant or any guarantor of the Lease from any liability under this Lease, including, without limitation, in connection with the
Subject Space. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any Transfer, and shall have the right to make copies thereof. If the Transfer
Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than two percent (2%), Tenant shall pay Landlord’s costs of such audit. 

14.6    Additional Transfers. For purposes of this Lease, the term “Transfer” shall also
include if Tenant is a partnership, the withdrawal or change, voluntary, involuntary or by operation of law, of fifty percent (50%) or more of the partners, or transfer of fifty percent (50%) or more of partnership interests, within a twelve
(12)-month period, or the dissolution of the partnership without immediate reconstitution thereof.

[Aligos Thereapeutics, Inc.]

 14.7    Occurrence of Default. Any Transfer hereunder
shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be terminated during the term of any Transfer, Landlord shall have the right to: (i) treat such Transfer as cancelled and repossess the Subject Space by
any lawful means, or (ii) require that such Transferee attorn to and recognize Landlord as its landlord under any such Transfer. If Tenant shall be in default under this Lease, Landlord is hereby irrevocably authorized, as Tenant’s agent
and attorney-in-fact, to direct any Transferee to make all payments under or in connection with the Transfer directly to Landlord (which Landlord shall apply towards
Tenant’s obligations under this Lease) until such default is cured. Such Transferee shall rely on any representation by Landlord that Tenant is in default hereunder, without any need for confirmation thereof by Tenant. Upon any assignment, the
assignee shall assume in writing all obligations and covenants of Tenant thereafter to be performed or observed under this Lease. No collection or acceptance of rent by Landlord from any Transferee shall be deemed a waiver of any provision of this
Article 14 or the approval of any Transferee or a release of Tenant from any obligation under this Lease, whether theretofore or thereafter accruing. In no event shall Landlord’s enforcement of any provision of this Lease against any
Transferee be deemed a waiver of Landlord’s right to enforce any term of this Lease against Tenant or any other person. If Tenant’s obligations hereunder have been guaranteed, Landlord’s consent to any Transfer shall not be effective
unless the guarantor also consents to such Transfer. 

14.8    Non-Transfers. Notwithstanding anything to the contrary
contained in this Article 14, (i) an assignment or subletting of all or a portion of the Premises to an affiliate of Tenant (an entity which is controlled by, controls, or is under common control with, Tenant),
(ii) an assignment of the Premises to an entity which acquires all or substantially all of the assets or interest (partnership, stock or other) of Tenant, or (iii) an assignment of the Premises to an entity which is the resulting entity of
a merger or consolidation of Tenant with another entity shall not be deemed a Transfer under this Article 14 (and for the avoidance of doubt, Sections 14.2, 14.3 and 14.4 shall not apply to such Transfer), provided that
Tenant notifies Landlord of any such assignment or sublease and promptly supplies Landlord with any documents or information requested by Landlord regarding such assignment or sublease or such affiliate, and further provided that such assignment or
sublease is not a subterfuge by Tenant to avoid its obligations under this Lease. “Control,” as used in this Section 14.8, shall mean the ownership, directly or indirectly, of at least fifty-one percent (51%) of the voting securities of, or possession of the right to vote, in the ordinary direction of its affairs, of at least fifty-one percent (51%) of the
voting interest in, any person or entity. No such permitted assignment or subletting shall serve to release Tenant from any of its obligations under this Lease. An assignee of Tenant’s entire interest under this
Section 14.8 is sometimes referred to as a “Permitted Assignee.” 

15.    SURRENDER OF PREMISES; OWNERSHIP AND REMOVAL OF TRADE FIXTURES. 

15.1    Surrender of Premises. No act or thing done by Landlord or any agent or employee of Landlord during
the Lease Term shall be deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in writing by Landlord. The delivery of keys to the Premises to Landlord or any agent or employee
of Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the return of such keys at
any reasonable time upon request until this Lease shall have been properly terminated. The voluntary or other surrender of this Lease by Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not work a merger, and at the
option of Landlord shall operate as an assignment to Landlord of all subleases or subtenancies affecting the Premises or terminate any or all such sublessees or subtenancies. 

15.2    Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or upon any earlier
termination of this Lease, Tenant shall, subject to the provisions of this Article 15, quit and surrender possession of the Premises to Landlord in as good order and condition as when Tenant took possession and as thereafter improved by
Landlord and/or Tenant, reasonable wear and tear, damage by casualty and condemnation, and repairs which are specifically made the responsibility of Landlord hereunder excepted. Upon such expiration or termination, Tenant shall, without expense to
Landlord, remove or cause to be removed from the Premises all debris and rubbish, and such items of furniture, equipment, free-standing cabinet work, movable partitions and other articles of personal property owned by Tenant or installed or placed
by Tenant at its expense in the Premises, and such similar articles of any other persons claiming under Tenant, as Landlord may, in its sole discretion, require to be removed, and Tenant shall repair at its own expense all damage to the Premises and
Building resulting from such removal.

[Aligos Thereapeutics, Inc.]

 15.3    Environmental Assessment. In connection with its
surrender of the Premises, Tenant shall submit to Landlord, at least sixty (60) days prior to the expiration date of this Lease (or in the event of an earlier termination of this Lease, as soon as reasonably possible following such
termination), an environmental Assessment of the Premises by a competent and experienced environmental engineer or engineering firm reasonably satisfactory to Landlord (pursuant to a contract approved by Landlord and providing that Landlord can rely
on the Environmental Assessment). If such Environmental Assessment reveals that remediation or Clean-up is required under any Environmental Laws, Tenant shall submit a remediation plan prepared by a recognized
environmental consultant and shall be responsible for all costs of remediation and Clean-up, as more particularly provided in Section 5.3, above. 

15.4    Condition of the Building and Premises Upon Surrender. In addition to the above requirements of this
Article 15, upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, surrender the Premises and Building with Tenant having complied with all of Tenant’s obligations under
this Lease, including those relating to improvement, repair, maintenance, compliance with law, testing and other related obligations of Tenant set forth in Article 7 of this Lease. In the event that the Building and
Premises shall be surrendered in a condition which does not comply with the terms of this Section 15.4, because Tenant failed to comply with its obligations set forth in Lease, then following thirty (30) days’
notice to Tenant, during which thirty (30) day period Tenant shall have the right to cure such noncompliance, Landlord shall be entitled to expend all reasonable costs in order to cause the same to comply with the required condition upon
surrender and Tenant shall promptly reimburse Landlord for all such costs upon notice and, during the period after the expiration or termination of this Lease, Tenant shall be deemed during the period that Tenant or Landlord, as the case may be,
perform obligations relating to the Surrender Improvements to be in holdover under Article 
16 of this Lease. 
 16.    HOLDING OVER. If Tenant holds over after the expiration of the Lease
Term or earlier termination thereof, with the express or implied consent of Landlord, such tenancy shall be from month-to-month only, and shall not constitute a renewal
hereof or an extension for any further term. If Tenant holds over after the expiration of the Lease Term of earlier termination thereof, without the express or implied consent of Landlord, such tenancy shall be deemed to be a tenancy by sufferance
only, and shall not constitute a renewal hereof or an extension for any further term. In either case, Rent shall be payable at a monthly rate equal to twice the Rent applicable during the last rental period of the Lease Term under this Lease. Such month-to-month tenancy or tenancy by sufferance, as the case may be, shall be subject to every other applicable term, covenant and agreement contained herein. Nothing
contained in this Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease
upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender
the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable
attorneys’ fees) and liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to surrender and any lost profits to Landlord resulting
therefrom. 
 17.    ESTOPPEL CERTIFICATES. Within ten (10) business days following a request
in writing by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit D, attached
hereto (or such other form as may be required by any prospective mortgagee or purchaser of the Project, or any portion thereof), indicating therein any exceptions thereto that may exist at that time, and shall also contain any other information
reasonably requested by Landlord or Landlord’s mortgagee or prospective mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project. Tenant shall execute and deliver whatever
other instruments may be reasonably required for such purposes. At any time during the Lease Term, Landlord may require Tenant to provide Landlord with a current financial statement and financial statements of the two (2) years prior to the
current financial statement year. Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the normal practice of Tenant, shall be audited by an independent certified public accountant. Landlord
shall hold such statements confidential. Failure of Tenant to timely execute, acknowledge and deliver such estoppel certificate or other instruments shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements
included in the estoppel certificate are true and correct, without exception.

 18.    SUBORDINATION. Landlord represents and
warrants that the Building and the Project are not currently subject to any ground or underlying lease, or to the lien of any mortgage or deed of trust. This Lease shall be subject and subordinate to all present and future ground or
underlying leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances now or hereafter in force against the Building or Project or any part thereof, if any, and to all renewals, extensions, modifications,
consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust deeds, unless the holders of such mortgages, trust deeds or other encumbrances, or the lessors under such ground
lease or underlying leases, require in writing that this Lease be superior thereto. The subordination of this Lease to any such future ground lease of the Building or Project or to the lien of any mortgage, deed of trust or other encumbrance, shall
be subject to Tenant’s receipt of a commercially reasonable subordination, non-disturbance and attornment agreement in favor of Tenant. Tenant covenants and agrees in the event any proceedings are brought
for the foreclosure of any such mortgage or deed in lieu thereof (or if any ground lease is terminated), to attorn, without any deductions or set-offs whatsoever, to the lienholder or purchaser or any
successors thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor, and to recognize such purchaser or lienholder or ground lessor as the lessor under this Lease, so long as Tenant timely pays the rent and observes
and performs the terms, covenants and conditions of this Lease to be observed and performed by Tenant. Landlord’s interest herein may be assigned as security at any time to any lienholder. Tenant shall, within ten (10) days of request by
Landlord, execute such further instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination or superiority of this Lease to any such mortgages, trust deeds, ground leases or underlying leases. Tenant
waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any
foreclosure proceeding or sale. 
 19.    DEFAULTS; REMEDIES. 

19.1    Events of Default. The occurrence of any of the following shall constitute a default of this Lease
by Tenant: 
 19.1.1    Any failure by Tenant to pay any Rent or any other charge required to be paid under this Lease,
or any part thereof, when due unless such failure is cured within five (5) business days after written notice; or 

19.1.2    Except where a specific time period is otherwise set forth for Tenant’s performance in this Lease, in which
event the failure to perform by Tenant within such time period shall be a default by Tenant under this Section 19.1.2, any failure by Tenant to observe or perform any other provision, covenant or condition of this Lease to
be observed or performed by Tenant where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided that if the nature of such default is such that the same cannot reasonably be cured within a
thirty (30) day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and cure such default; or 

19.1.3    Abandonment or vacation of all or a substantial portion of the Premises by Tenant; or 

19.1.4    The failure by Tenant to observe or perform according to the provisions of Articles 5, 14,
17 or 18 of this Lease where such failure continues for more than five (5) business days after notice from Landlord; or 

19.1.5    Tenant’s failure to occupy the Premises within ten (10) business days after the Rent Commencement
Date. 
 The notice periods provided herein are in lieu of, and not in addition to, any notice periods provided by law. 

19.2    Remedies Upon Default. Upon the occurrence and during the continuance of any event of default by
Tenant, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity (all of which remedies shall be distinct, separate and cumulative), the option to pursue any one or more of the following remedies, each and all
of which shall be cumulative and nonexclusive, without any notice or demand whatsoever.

[Aligos Thereapeutics, Inc.]

 19.2.1    Terminate this Lease, in which event Tenant shall immediately
surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant
and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim or damages therefor; and Landlord may recover from Tenant the following: 

(i)    The worth at the time of award of the unpaid rent which has been earned at the time of such
termination; plus 
 (ii)    The worth at the time of award of the amount by which the unpaid rent which
would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus 

(iii)    The worth at the time of award of the amount by which the unpaid rent for the balance of the Lease
Term after the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus 

(iv)    Any other amount necessary to compensate Landlord for all the detriment proximately caused by
Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, specifically including but not limited to, brokerage commissions and advertising expenses incurred to
obtain a new tenant, expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant; and 

(v)    At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be
permitted from time to time by applicable law. 
 The term “rent” as used in this Section 19.2
shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 19.2.1(i) and (ii), above, the “worth at the time
of award” shall be computed by allowing interest at the rate set forth in Article 25 of this Lease, but in no case greater than the maximum amount of such interest permitted by law. As used in
Section 19.2.1(iii) above, the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one
percent (1%). 
 19.2.2    Landlord shall have the remedy described in California Civil Code Section 1951.4 (lessor
may continue lease in effect after lessee’s breach and abandonment and recover rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations). Accordingly, if Landlord does not elect to terminate
this Lease on account of any default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due. 

19.2.3    Landlord shall at all times have the rights and remedies (which shall be cumulative with each other and
cumulative and in addition to those rights and remedies available under Sections 19.2.1 and 19.2.2, above, or any law or other provision of this Lease), without prior demand or notice except as required by applicable law, to seek any
declaratory, injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof. 

19.3    Subleases of Tenant. Whether or not Landlord elects to terminate this Lease on account of any
default by Tenant, as set forth in this Article 19, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or
may, in Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. In the event of Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses,
concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

 19.4    Efforts to Relet. No re-entry or repossession, repairs, maintenance, changes, alterations and additions, reletting, appointment of a receiver to protect Landlord’s interests hereunder, or any other action or omission by Landlord
shall be construed as an election by Landlord to terminate this Lease or Tenant’s right to possession, or to accept a surrender of the Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant’s obligations
hereunder, unless express written notice of such intention is sent by Landlord to Tenant. Tenant hereby irrevocably waives any right otherwise available under any law to redeem or reinstate this Lease. 

19.5    Landlord Default. 

19.5.1    General. Notwithstanding anything to the contrary set forth in this Lease, Landlord shall not be
in default in the performance of any obligation required to be performed by Landlord pursuant to this Lease unless Landlord fails to perform such obligation within thirty (30) days after the receipt of notice from Tenant specifying in detail
Landlord’s failure to perform; provided, however, if the nature of Landlord’s obligation is such that more than thirty (30) days are required for its performance, then Landlord shall not be in default under this Lease if it shall
commence such performance within such thirty (30) day period and thereafter diligently pursue the same to completion. Upon any such default by Landlord under this Lease, Tenant may, except as otherwise specifically provided in this Lease to the
contrary, exercise any of its rights provided at law or in equity. 
 19.5.2    Abatement of Rent. In the
event that Tenant is prevented from using, and does not use, the Premises or any portion thereof, as a result of (i) any repair, maintenance or alteration performed by Landlord, or which Landlord failed to perform, after the Rent Commencement
Date and required by this Lease, or (ii) any failure to provide services, utilities or access to the Premises as required by this Lease, each as a direct result of Landlord’s, negligence or willful misconduct or breach of this Lease (and
except to the extent such failure is caused in whole or in part by the action or inaction of Tenant) (any such set of circumstances as set forth in items (i) or (ii), above, to be known as an “Abatement Event”), then Tenant
shall give Landlord notice of such Abatement Event, and if such Abatement Event continues for five (5) consecutive business days after Landlord’s receipt of any such notice (the “Eligibility Period”), then the Base Rent,
Tenant’s Share of Direct Expenses, and Tenant’s obligation, if any, to pay for parking (to the extent not utilized by Tenant) shall be abated or reduced, as the case may be, after expiration of the Eligibility Period for such time that
Tenant continues to be so prevented from using, and does not use for the normal conduct of Tenant’s business, the Premises or a portion thereof, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented
from using, and does not use, bears to the total rentable area of the Premises; provided, however, in the event that Tenant is prevented from using, and does not use, a portion of the Premises for a period of time in excess of the Eligibility Period
and the remaining portion of the Premises is not sufficient to allow Tenant to effectively conduct its business therein, and if Tenant does not effectively conduct its business from such remaining portion, then for such time after expiration of the
Eligibility Period during which Tenant is so prevented from effectively conducting its business therein, the Base Rent and Tenant’s Share of Direct Expenses for the entire Premises and Tenant’s obligation to pay for parking shall be abated
for such time as Tenant continues to be so prevented from using, and does not use, the Premises. If, however, Tenant reoccupies any portion of the Premises during such period, the Rent allocable to such reoccupied portion, based on the proportion
that the rentable area of such reoccupied portion of the Premises bears to the total rentable area of the Premises, shall be payable by Tenant from the date Tenant reoccupies such portion of the Premises. To the extent an Abatement Event is caused
by an event covered by Articles 5, 11 or 13 of this Lease, then Tenant’s right to abate rent shall be governed by the terms of such Article 5, 11 or 13, as applicable, and the Eligibility Period shall not be applicable
thereto. Except as provided in this Section 19.5.2, nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder. 

20.    COVENANT OF QUIET ENJOYMENT. Landlord covenants that Tenant, on paying the Rent, charges
for services and other payments herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant to be kept, observed and performed within the
notice and cure periods provided for herein, shall, during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions and agreements hereof without interference by any persons
lawfully claiming by or through Landlord. The foregoing covenant is in lieu of any other covenant express or implied.

 21.    LETTER OF CREDIT 

21.1    Delivery of Letter of Credit. Tenant shall deliver to Landlord, concurrently with Tenant’s
execution of this Lease, an unconditional, clean, irrevocable letter of credit (the “L-C”) in the amount set forth in Section 8 of the Lease Summary (the
“L-C Amount”), which L-C shall be issued by a money-center, solvent and nationally recognized bank (a bank which accepts deposits, maintains
accounts, has a local San Francisco Bay Area office which will negotiate a letter of credit, and whose deposits are insured by the FDIC) reasonably acceptable to Landlord (such approved, issuing bank being referred to herein as the
“Bank”), which Bank must have a rating from Standard and Poors Corporation of A- or better (or any equivalent rating thereto from any successor or substitute rating service selected by
Landlord) and a letter of credit issuer rating from Moody’s Investor Service of A3 or better (or any equivalent rating thereto from any successor rating agency thereto)) (collectively, the “Bank’s Credit Rating Threshold”), and
which L-C shall be substantially in the form of Exhibit F, attached hereto. Landlord hereby approves Silicon Valley Bank as the Bank for the
L-C to be initially delivered by Tenant. Tenant shall pay all expenses, points and/or fees incurred by Tenant in obtaining the L-C. The
L-C shall (i) be “callable” at sight, irrevocable and unconditional, (ii) be maintained in effect, whether through renewal or extension, for the period commencing on the date of this Lease
and continuing until the date (the “L-C Expiration Date”) that is no less than sixty (60) days after the expiration of the Lease Term as the same may be extended, and Tenant shall deliver a
new L-C or certificate of renewal or extension to Landlord at least thirty (30) days prior to the expiration of the L-C then held by Landlord, without any action
whatsoever on the part of Landlord, (iii) be fully assignable by Landlord, its successors and assigns, (iv) permit partial draws and multiple presentations and drawings, and (v) be otherwise subject to the Uniform Customs and
Practices for Documentary Credits (1993-Rev), International Chamber of Commerce Publication #500, or the International Standby Practices-ISP 98, International Chamber of
Commerce Publication #590. Landlord shall have the right to draw down an amount up to the face amount of the L-C if any of the following shall have occurred or be applicable: (A) such amount is due to
Landlord under the terms and conditions of this Lease, and has not been paid within applicable notice and cure periods (or, if Landlord is prevented by law from providing notice, within the period for payment set forth in the Lease), or
(B) Tenant has filed a voluntary petition under the U. S. Bankruptcy Code or any state bankruptcy code (collectively, “Bankruptcy Code”), or (C) an involuntary petition has been filed against Tenant under the
Bankruptcy Code that is not dismissed within thirty (30) days, or (D) the Lease has been rejected, or is deemed rejected, under Section 365 of the U.S. Bankruptcy Code, following the filing of a voluntary petition by Tenant under the
Bankruptcy Code, or the filing of an involuntary petition against Tenant under the Bankruptcy Code, or (E) the Bank has notified Landlord that the L-C will not be renewed or extended through the L-C Expiration Date, and Tenant has not provided a replacement L-C that satisfies the requirements of this Lease at least thirty (30) days prior to such expiration, or
(F) Tenant is placed into receivership or conservatorship, or becomes subject to similar proceedings under Federal or State law, or (G) Tenant executes an assignment for the benefit of creditors, or (H) if (1) any of the
Bank’s Fitch Ratings (or other comparable ratings to the extent the Fitch Ratings are no longer available) have been reduced below the Bank’s Credit Rating Threshold, or (2) there is otherwise a material adverse change in the
financial condition of the Bank, and Tenant has failed to provide Landlord with a replacement letter of credit, conforming in all respects to the requirements of this Article 21 (including, but not limited to, the
requirements placed on the issuing Bank more particularly set forth in this Section 21.1 above), in the amount of the applicable L-C Amount, within ten (10) business days
following Landlord’s written demand therefor (with no other notice or cure or grace period being applicable thereto, notwithstanding anything in this Lease to the contrary) (each of the foregoing being an “L-C Draw Event”). The L-C shall be honored by the Bank regardless of whether Tenant disputes Landlord’s right to draw upon the
L-C. In addition, in the event the Bank is placed into receivership or conservatorship by the Federal Deposit Insurance Corporation or any successor or similar entity, then, effective as of the date such
receivership or conservatorship occurs, said L-C shall be deemed to fail to meet the requirements of this Article 21, and, within ten (10) business days following Landlord’s
notice to Tenant of such receivership or conservatorship (the “L-C FDIC Replacement Notice”), Tenant shall replace such L-C with a substitute letter of credit
from a different issuer (which issuer shall meet or exceed the Bank’s Credit Rating Threshold and shall otherwise be acceptable to Landlord in its reasonable discretion) and that complies in all respects with the requirements of this
Article 21. If Tenant fails to replace such L-C with such conforming, substitute letter of credit pursuant to the terms and conditions of this Section 21.1,
then, notwithstanding anything in this Lease to the contrary, Landlord shall have the right to declare Tenant in default of this Lease for which there shall be no notice or grace or cure periods being applicable thereto (other than the aforesaid ten
(10) business day period). Tenant shall be responsible for the payment of any and all Tenant’s and Bank’s costs incurred with the review of any replacement L-C, which replacement is required
pursuant to this Section or is otherwise requested by Tenant. In the event of an assignment by Tenant of its 

  

					
		 	-33-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
interest in this Lease (and irrespective of whether Landlord’s consent is required for such assignment), the acceptance of any replacement or substitute letter of credit by Landlord from the
assignee shall be subject to Landlord’s prior written approval, in Landlord’s reasonable discretion, and the actual and reasonable attorney’s fees incurred by Landlord in connection with such determination shall be payable by Tenant
to Landlord within thirty (30) days of billing. 
 21.2    Application of L-C. Tenant hereby acknowledges and agrees that Landlord is entering into this Lease in material reliance upon the ability of Landlord to draw upon the L-C
upon the occurrence of any L-C Draw Event. In the event of any L-C Draw Event, Landlord may, but without obligation to do so, and without notice to Tenant (except in
connection with an L-C Draw Event under Section 21.1(H) above), draw upon the L-C, in part or in whole, in the amount necessary to cure any
such L-C Draw Event and/or to compensate Landlord for any and all damages of any kind or nature sustained or which Landlord reasonably estimates that it will sustain resulting from Tenant’s breach or
default of this Lease or other L-C Draw Event and/or to compensate Landlord for any and all damages arising out of, or incurred in connection with, the termination of this Lease, including, without limitation,
those specifically identified in Section 1951.2 of the California Civil Code. The use, application or retention of the L-C, or any portion thereof, by Landlord shall not prevent Landlord from exercising
any other right or remedy provided by this Lease or by any applicable law, it being intended that Landlord shall not first be required to proceed against the L-C, and such
L-C shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled. Tenant agrees and acknowledges that (i) the L-C constitutes a
separate and independent contract between Landlord and the Bank, (ii) Tenant is not a third party beneficiary of such contract, (iii) Tenant has no property interest whatsoever in the L-C or the
proceeds thereof, and (iv) in the event Tenant becomes a debtor under any chapter of the Bankruptcy Code, Tenant is placed into receivership or conservatorship, and/or there is an event of a receivership, conservatorship or a bankruptcy filing
by, or on behalf of, Tenant, neither Tenant, any trustee, nor Tenant’s bankruptcy estate shall have any right to restrict or limit Landlord’s claim and/or rights to the L-C and/or the proceeds
thereof by application of Section 502(b)(6) of the U. S. Bankruptcy Code or otherwise. 

21.3    Maintenance of L-C by Tenant. If, as a result of any drawing
by Landlord of all or any portion of the L-C, the amount of the L-C shall be less than the L-C Amount, Tenant shall, within ten
(10) business days thereafter, provide Landlord with additional letter(s) of credit in an amount equal to the deficiency, and any such additional letter(s) of credit shall comply with all of the provisions of this Article 21. Tenant
further covenants and warrants that it will neither assign nor encumber the L-C or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such assignment, encumbrance,
attempted assignment or attempted encumbrance. Without limiting the generality of the foregoing, if the L-C expires earlier than the L-C Expiration Date, Landlord will
accept a renewal thereof (such renewal letter of credit to be in effect and delivered to Landlord, as applicable, not later than thirty (30) days prior to the expiration of the L-C), which shall be
irrevocable and automatically renewable as above provided through the L-C Expiration Date upon the same terms as the expiring L-C or such other terms as may be
acceptable to Landlord in its reasonable discretion. If Tenant exercises its option to extend the Lease Term pursuant to Section 2.2 of this Lease then, not later than thirty (30) days prior to the commencement of the
Option Term, Tenant shall deliver to Landlord a new L C or certificate of renewal or extension evidencing the L-C Expiration Date as thirty (30) days after the expiration of the Option Term. However,
if the L-C is not timely renewed, or if Tenant fails to maintain the L-C in the amount and in accordance with the terms set forth in this
Article 21, Landlord shall have the right to present the L-C to the Bank in accordance with the terms of this Article 21, and the proceeds of the L-C shall be applied by Landlord against any Rent payable by Tenant under this Lease that is not paid when due and/or to pay for all losses and damages that Landlord has suffered or that Landlord reasonably
estimates that it will suffer as a result of any breach or default by Tenant under this Lease. In the event Landlord elects to exercise its rights as provided above, (I) any unused proceeds shall constitute the property of Landlord (and not
Tenant’s property or, in the event of a receivership, conservatorship, or a bankruptcy filing by, or on behalf of, Tenant, property of such receivership, conservatorship or Tenant’s bankruptcy estate) and need not be segregated from
Landlord’s other assets, and (II) Landlord agrees to pay to Tenant within thirty (30) days after the L-C Expiration Date the amount of any proceeds of the
L-C received by Landlord and not applied against any Rent payable by Tenant under this Lease that was not paid when due or used to pay for any losses and/or damages suffered by Landlord (or reasonably
estimated by Landlord that it will suffer) as a result of any breach or default by Tenant under this Lease; provided, however, that if prior to the L-C Expiration Date a voluntary petition is filed by Tenant,
or an involuntary petition is filed against Tenant by any of Tenant’s creditors, under the Bankruptcy Code, then Landlord shall not be obligated to make such payment in the amount of the unused L-C
proceeds until either all preference issues relating to payments under this 

  

					
		 	-34-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
Lease have been resolved in such bankruptcy or reorganization case or such bankruptcy or reorganization case has been dismissed. If Landlord draws on the
L-C due to Tenant’s failure to timely renew or provide a replacement L-C, such failure shall not be considered a default under this Lease and Landlord shall return
such cash proceeds upon Tenant’s presentation of a replacement L-C that satisfies the requirements of this Lease, subject to reasonable satisfaction of any preference risk to Landlord. 

21.4    Transfer and Encumbrance. The L-C shall also provide that
Landlord may, at any time and without notice to Tenant and without first obtaining Tenant’s consent thereto, transfer (one or more times) all of its interest in and to the L-C to another party, person or
entity, regardless of whether or not such transfer is from in connection with the assignment by Landlord all of its rights and interests in and to this Lease. In the event of a transfer of Landlord’s interest in under this Lease, Landlord shall
transfer the L-C, in whole or in part, to the transferee and thereupon Landlord shall, without any further agreement between the parties, be released by Tenant from all liability therefor, and it is agreed
that the provisions hereof shall apply to every transfer or assignment of the whole of said L-C to a new landlord. In connection with any such transfer of the L-C by
Landlord, Tenant shall, at Tenant’s sole cost and expense, execute and submit to the Bank such applications, documents and instruments as may be necessary to effectuate such transfer and, Tenant shall be responsible for paying the Bank’s
transfer and processing fees in connection therewith; provided that, Landlord shall have the right (in its sole discretion), but not the obligation, to pay such fees on behalf of Tenant, in which case Tenant shall reimburse Landlord within ten
(10) business days after Tenant’s receipt of an invoice from Landlord therefor. 
 21.5    L-C Not a Security Deposit. Landlord and Tenant (1) acknowledge and agree that in no event or circumstance shall the L-C or any renewal thereof or substitute
therefor or any proceeds thereof be deemed to be or treated as a “security deposit” under any law applicable to security deposits in the commercial context, including, but not limited to, Section 1950.7 of the California Civil Code,
as such Section now exists or as it may be hereafter amended or succeeded (the “Security Deposit Laws”), (2) acknowledge and agree that the L-C (including any renewal thereof or
substitute therefor or any proceeds thereof) is not intended to serve as a security deposit, and the Security Deposit Laws shall have no applicability or relevancy thereto, and (3) waive any and all rights, duties and obligations that any such
party may now, or in the future will, have relating to or arising from the Security Deposit Laws. Tenant hereby irrevocably waives and relinquishes the provisions of Section 1950.7 of the California Civil Code and any successor statute, and all
other provisions of law, now or hereafter in effect, which (x) establish the time frame by which a landlord must refund a security deposit under a lease, and/or (y) provide that a landlord may claim from a security deposit only those sums
reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by a tenant or to clean the premises, it being agreed that Landlord may, in addition, claim those sums specified in this Article 21
and/or those sums reasonably necessary to (a) compensate Landlord for any loss or damage caused by Tenant’s breach of this Lease, including any damages Landlord suffers following termination of this Lease, and/or (b) compensate
Landlord for any and all damages arising out of, or incurred in connection with, the termination of this Lease, including, without limitation, those specifically identified in Section 1951.2 of the California Civil Code. 

21.6    Non-Interference By Tenant. Tenant agrees not to interfere
in any way with any payment to Landlord of the proceeds of the L-C, either prior to or following a “draw” by Landlord of all or any portion of the L-C,
regardless of whether any dispute exists between Tenant and Landlord as to Landlord’s right to draw down all or any portion of the L-C. No condition or term of this Lease shall be deemed to render the L-C conditional and thereby afford the Bank a justification for failing to honor a drawing upon such L-C in a timely manner.    Tenant shall not request or
instruct the Bank of any L-C to refrain from paying sight draft(s) drawn under such L-C. 

21.7    Waiver of Certain Relief. Tenant unconditionally and irrevocably waives (and as an independent
covenant hereunder, covenants not to assert) any right to claim or obtain any of the following relief in connection with the L-C: 

21.7.1    A temporary restraining order, temporary injunction, permanent injunction, or other order that would prevent,
restrain or restrict the presentment of sight drafts drawn under any L-C or the Bank’s honoring or payment of sight draft(s); or 

  

					
		 	-35-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 21.7.2    Any attachment, garnishment, or levy in any manner upon either
the proceeds of any L-C or the obligations of the Bank (either before or after the presentment to the Bank of sight drafts drawn under such L-C) based on any theory
whatever. 
 21.8    Remedy for Improper Drafts. Tenant’s sole remedy in connection with the improper
presentment or payment of sight drafts drawn under any L-C shall be the right to obtain from Landlord a refund of the amount of any sight draft(s) that were improperly presented or the proceeds of which were
misapplied, and reasonable actual out-of-pocket costs and expenses and attorneys’ fees, provided that at the time of such refund, Tenant increases the amount of
such L-C to the amount (if any) then required under the applicable provisions of this Lease. Tenant acknowledges that the presentment of sight drafts drawn under any
L-C, or the Bank’s payment of sight drafts drawn under such L-C, could not under any circumstances cause Tenant injury that could not be remedied by an award of
money damages, and that the recovery of money damages would be an adequate remedy therefor. In the event Tenant shall be entitled to a refund as aforesaid and Landlord shall fail to make such payment within ten (10) business days after demand,
Tenant shall have the right to deduct the amount thereof from the next installment(s) of Base Rent. 

22.    COMMUNICATIONS AND COMPUTER LINE. Tenant may install, maintain, replace, remove or use
any communications or computer wires and cables serving the Premises (collectively, the “Lines”), provided that Tenant shall coordinate any such installation with Landlord, use an experienced and qualified contractor approved in
writing by Landlord, and otherwise comply with all of the other provisions of Articles 7 and 8 of this Lease. Tenant shall pay all costs in connection therewith. Landlord reserves the right, upon notice to Tenant prior to the
expiration or earlier termination of this Lease, to require that Tenant, at Tenant’s sole cost and expense, remove any Lines located in or serving the Premises upon to the expiration or earlier termination of this Lease. 

23.    SIGNS 

23.1    Exterior Signage. Subject to Landlord’s prior written approval, which shall not be unreasonably
withheld, conditioned or delayed, and provided all signs are in keeping with the quality, design and style of the Building and Project, Tenant, at its sole cost and expense, may install (i) identification signage on any existing monument sign
located at the exterior of the Project, (ii) signage at the entrance to the Building (on a pro-rata basis based upon the respective square footage of the tenants in the Building), and (iii) any
internal directional, lobby and directory signage (collectively, “Tenant Signage”); provided, however, in no event shall Tenant’s Signage include an “Objectionable Name,” as that term is defined in
Section 23.3, of this Lease. All such signage shall be subject to Tenant’s obtaining all required governmental approvals. All permitted signs shall be maintained by Tenant at its expense in a first-class and safe
condition and appearance. Upon the expiration or earlier termination of this Lease, Tenant shall remove all of its signs at Tenant’s sole cost and expense. The graphics, materials, color, design, lettering, lighting, size, illumination,
specifications and exact location of Tenant’s Signage (collectively, the “Sign Specifications”) shall be subject to the prior written approval of Landlord, which approval shall not be unreasonably withheld, conditioned or
delayed, and shall be consistent and compatible with the quality and nature of the Project. Tenant hereby acknowledges that, notwithstanding Landlord’s approval of Tenant’s Signage, Landlord has made no representation or warranty to Tenant
with respect to the probability of obtaining all necessary governmental approvals and permits for Tenant’s Signage. In the event Tenant does not receive the necessary governmental approvals and permits for Tenant’s Signage, Tenant’s
and Landlord’s rights and obligations under the remaining terms and conditions of this Lease shall be unaffected. 

23.2    Objectionable Name. Tenant’s Signage shall not include a name or logo which relates to an
entity which is of a character or reputation, or is associated with a political faction or orientation, which is inconsistent with the quality of the Project, or which would otherwise reasonably offend a landlord of the Comparable Buildings (an
“Objectionable Name”). The parties hereby agree that the following name, or any reasonable derivation thereof, shall be deemed not to constitute an Objectionable Name: “Aligos Therapeutics, Inc.” 

23.3    Prohibited Signage and Other Items. Any signs, notices, logos, pictures, names or advertisements
which are installed and that have not been separately approved by Landlord may be removed without notice by Landlord at the sole expense of Tenant. Any signs, window coverings, or blinds (even if the same are located behind the Landlord-approved
window coverings for the Building), or other items visible from the exterior of the Premises or Building, shall be subject to the prior approval of Landlord, in its reasonable discretion.

 23.4    Termination of Right to Tenant’s Signage. The
rights contained in this Article 23 shall be personal to Original Tenant and its Permitted Assignee, and may only be exercised and maintained by such parties (and not any other assignee, sublessee or other transferee of the
Original Tenant’s interest in this Lease) to the extent (x) they are not in default under this Lease (beyond any applicable notice and cure period) and (y) if they occupy the entire Premises. 

24.    COMPLIANCE WITH LAW. Tenant shall not do anything or suffer anything to be done in or
about the Premises or the Project which will in any way conflict with any law, statute, ordinance or other governmental rule, regulation or requirement now in force or which may hereafter be enacted or promulgated. At its sole cost and expense,
Tenant shall promptly comply with all such governmental measures pertaining to Tenant’s use of the Premises. Should any standard or regulation now or hereafter be imposed on Landlord or Tenant by a state, federal or local governmental body
charged with the establishment, regulation and enforcement of occupational, health or safety standards for employers, employees, landlords or tenants, then Tenant agrees, at its sole cost and expense, to comply promptly with such standards or
regulations. Tenant shall be responsible, at its sole cost and expense, to make all alterations to the Building and Premises as are required to comply with the governmental rules, regulations, requirements or standards described in this Article
24 that pertain to Tenant’s use of the Premises. The judgment of any court of competent jurisdiction or the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any of said
governmental measures, shall be conclusive of that fact as between Landlord and Tenant. For purposes of Section 1938 of the California Civil Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that the Project, Building
and Premises have not undergone inspection by a Certified Access Specialist (CASp). As required by Section 1938(e) of the California Civil Code, Landlord hereby states as follows: “A Certified Access Specialist (CASp) can inspect the
subject premises and determine whether the subject premises comply with all of the applicable construction-related accessibility standards under state law. Although state law does not require a CASp inspection of the subject premises, the commercial
property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall
mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for the CASp inspection, and the cost of making any repairs necessary to correct violations of construction-related accessibility standards
within the premises.” In furtherance of the foregoing, Landlord and Tenant hereby agree as follows: (a) any CASp inspection requested by Tenant shall be conducted, at Tenant’s sole cost and expense, by a CASp approved in advance by
Landlord; and (b) Tenant, at its cost, is responsible for making any repairs within the Premises to correct violations of construction-related accessibility standards; and, if anything done by or for Tenant in its use or occupancy of the
Premises after the construction and installation of the Landlord TI Work pursuant to the Tenant Work Letter shall require repairs to the Building (outside the Premises) to correct violations of construction-related accessibility standards, then
Tenant shall, at Landlord’s option, either perform such repairs at Tenant’s sole cost and expense or reimburse Landlord upon demand, as Additional Rent, for the cost to Landlord of performing such repairs. 

25.    LATE CHARGES. If any installment of Rent or any other sum due from
Tenant shall not be received by Landlord or Landlord’s designee within five (5) business days after Tenant’s receipt of written notice from Landlord that said amount is due, then Tenant shall pay to Landlord a late charge equal to
five percent (5%) of the overdue amount plus any reasonable attorneys’ fees incurred by Landlord by reason of Tenant’s failure to pay Rent and/or other charges when due hereunder. The late charge shall be deemed Additional Rent and the
right to require it shall be in addition to all of Landlord’s other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting Landlord’s remedies in any manner. In addition to the late charge
described above, any Rent or other amounts owing hereunder which are not paid within ten (10) days after the date they are due shall bear interest from the date when due until paid at a rate per annum equal to the lesser of (i) the annual
“Bank Prime Loan” rate cited in the Federal Reserve Statistical Release Publication G.13(415), published on the first Tuesday of each calendar month (or such other comparable index as Landlord and Tenant shall reasonably agree upon if such
rate ceases to be published) plus four (4) percentage points, and (ii) 
the highest rate permitted by applicable law. 
 26.    LANDLORD’S RIGHT TO CURE DEFAULT; PAYMENTS
BY TENANT. 
 26.1    Landlord’s Cure. All covenants and agreements to be kept or performed by
Tenant under this Lease shall be performed by Tenant at Tenant’s sole cost and expense and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant shall fail to perform any obligation under
this Lease, 

  

					
		 	-37-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
and such failure shall continue in excess of the time allowed under Section 19.1.2, above, unless a specific time period is otherwise stated in this Lease, Landlord may,
but shall not be obligated to, make any such payment or perform any such act on Tenant’s part without waiving its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder. 

26.2    Tenant’s Reimbursement. Except as may be specifically provided to the contrary in this Lease,
Tenant shall pay to Landlord, upon delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in connection with the remedying by Landlord of Tenant’s defaults
pursuant to the provisions of Section 26.1; (ii) sums equal to all losses, costs, liabilities, damages and expenses referred to in Article 10 of this Lease; and (iii) sums equal to all expenditures made and
obligations incurred by Landlord in collecting or attempting to collect the Rent or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to law, including, without limitation, all reasonable legal fees and other
amounts so expended (subject to Section 29.21 below). Tenant’s obligations under this Section 26.2 shall survive the expiration or sooner termination of the Lease Term. 

27.    ENTRY BY LANDLORD. Landlord reserves the right and upon twenty four
(24) hours’ prior notice to Tenant (except in the case of an emergency) to enter the Premises at all reasonable times to (i) inspect them; (ii) show the Premises to prospective purchasers, or to current or prospective mortgagees,
ground or underlying lessors or insurers or, during the last twelve (12) months of the Lease Term, to prospective tenants; (iii) post notices of non-responsibility (to the extent applicable pursuant
to then applicable law); or (iv) alter, improve or repair the Premises or the Building, or for structural alterations, repairs or improvements to the Building or the Building’s systems and equipment. Landlord may make any such entries
without the abatement of Rent, except as otherwise provided in this Lease, and may take such reasonable steps as required to accomplish the stated purposes. In an emergency, Landlord shall have the right to use any means that Landlord may deem
proper to open the doors in and to the Premises. Any entry into the Premises by Landlord in the manner hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an actual or constructive
eviction of Tenant from any portion of the Premises. Landlord shall use commercially reasonable efforts to minimize any interference with Tenant’s use of or access to the Premises in connection with any such entry, and such comply with
Tenant’s reasonable security measures. Without limiting the foregoing, except in an emergency, Landlord shall not enter into any portion of the Premises identified to Landlord as an area containing sensitive business information unless
accompanied by a representative of Tenant. Landlord shall hold confidential any information regarding Tenant’s business learned as a result of any such entry 

28.    TENANT PARKING. Tenant shall have the right to use the amount of parking set forth in
Section 9 of the Summary, in the on-site and/or off-site, as the case may be, parking facility (or facilities) which serve the Project. Tenant
shall abide by all reasonable rules and regulations which are prescribed from time to time for the orderly operation and use of the parking facility where the parking passes are located (including any sticker or other identification system
established by Landlord and the prohibition of vehicle repair and maintenance activities in the parking facilities), and shall cooperate in seeing that Tenant’s employees and visitors also comply with such rules and regulations. Tenant’s
use of the Project parking facility shall be at Tenant’s sole risk and Tenant acknowledges and agrees that Landlord shall have no liability whatsoever for damage to the vehicles of Tenant, its employees and/or visitors, or for other personal
injury or property damage or theft relating to or connected with the parking rights granted herein or any of Tenant’s, its employees’ and/or visitors’ use of the parking facilities. 

29.    MISCELLANEOUS PROVISIONS. 

29.1    Terms; Captions. The words “Landlord” and “Tenant” as used herein
shall include the plural as well as the singular. The necessary grammatical changes required to make the provisions hereof apply either to corporations or partnerships or individuals, men or women, as the case may require, shall in all cases be
assumed as though in each case fully expressed. The captions of Articles and Sections are for convenience only and shall not be deemed to limit, construe, affect or alter the meaning of such Articles and Sections. 

29.2    Binding Effect. Subject to all other provisions of this Lease, each of the covenants, conditions and
provisions of this Lease shall extend to and shall, as the case may require, bind or inure to the benefit not only of 

  

					
		 	-38-	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
Landlord and of Tenant, but also of their respective heirs, personal representatives, successors or assigns, provided this clause shall not permit any assignment by Tenant contrary to the
provisions of Article 14 of this Lease. 
 29.3    No Air Rights. No rights to any view or to light
or air over any property, whether belonging to Landlord or any other person, are granted to Tenant by this Lease. If at any time any windows of the Premises are temporarily darkened or the light or view therefrom is obstructed by reason of any
repairs, improvements, maintenance or cleaning in or about the Project, the same shall be without liability to Landlord and without any reduction or diminution of Tenant’s obligations under this Lease. 

29.4    Modification of Lease. Should any current or prospective mortgagee or ground lessor for the Building
or Project require a modification of this Lease, which modification will not cause an increased cost or expense to Tenant or in any other way materially and adversely change the rights and obligations of Tenant hereunder, then and in such event,
Tenant agrees that this Lease may be so modified and agrees to execute whatever documents are reasonably required therefor and to deliver the same to Landlord within ten (10) business days following a request therefor. At the request of
Landlord or any mortgagee or ground lessor, Tenant agrees to execute a short form of Lease and deliver the same to Landlord within ten (10) business days following the request therefor. 

29.5    Transfer of Landlord’s Interest. Tenant acknowledges that Landlord has the right to transfer
all or any portion of its interest in the Project or Building and in this Lease, and Tenant agrees that in the event of any such transfer, Landlord shall automatically be released from all liability under this Lease and Tenant agrees to look solely
to such transferee for the performance of Landlord’s obligations hereunder after the date of transfer and such transferee shall be deemed to have fully assumed and be liable for all obligations of this Lease to be performed by Landlord,
including the return of any Security Deposit, and Tenant shall attorn to such transferee. 
 29.6    Prohibition
Against Recording. Except as provided in Section 29.4 of this Lease, neither this Lease, nor any memorandum, affidavit or other writing with respect thereto, shall be recorded by Tenant or by anyone acting through,
under or on behalf of Tenant. 
 29.7    Landlord’s Title. Landlord’s title is and always shall
be paramount to the title of Tenant. Nothing herein contained shall empower Tenant to do any act which can, shall or may encumber the title of Landlord. 

29.8    Relationship of Parties. Nothing contained in this Lease shall be deemed or construed by the parties
hereto or by any third party to create the relationship of principal and agent, partnership, joint venturer or any association between Landlord and Tenant. 

29.9    Application of Payments. Landlord shall have the right to apply payments received from Tenant
pursuant to this Lease, regardless of Tenant’s designation of such payments, to satisfy any obligations of Tenant hereunder, in such order and amounts as Landlord, in its sole discretion, may elect. 

29.10    Time of Essence. Time is of the essence with respect to the performance of every provision of this
Lease in which time of performance is a factor. 
 29.11    Partial Invalidity. If any term, provision or
condition contained in this Lease shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term, provision or condition to persons or circumstances other than those with respect to which it is
invalid or unenforceable, shall not be affected thereby, and each and every other term, provision and condition of this Lease shall be valid and enforceable to the fullest extent possible permitted by law. 

29.12    No Warranty. In executing and delivering this Lease, Tenant has not relied on any representations,
including, but not limited to, any representation as to the amount of any item comprising Additional Rent or the amount of the Additional Rent in the aggregate or that Landlord is furnishing the same services to other tenants, at all, on the same
level or on the same basis, or any warranty or any statement of Landlord which is not set forth herein or in one or more of the exhibits attached hereto.

[Aligos Thereapeutics, Inc.]

 29.13    Landlord Exculpation. The liability of Landlord
or the Landlord Parties to Tenant for any default by Landlord under this Lease or arising in connection herewith or with Landlord’s operation, management, leasing, repair, renovation, alteration or any other matter relating to the Project or
the Premises shall be limited solely and exclusively to the interest of Landlord in the Project, including any sales or insurance proceeds received by Landlord or the Landlord Parties in connection with the Project, Building or Premises. None of the
Landlord Parties (except Landlord) shall have any personal liability therefor, and Tenant hereby expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or under Tenant. The limitations of
liability contained in this Section 29.13 shall inure to the benefit of Landlord’s and the Landlord Parties’ present and future partners, beneficiaries, officers, directors, trustees, shareholders, agents and
employees, and their respective partners, heirs, successors and assigns. Under no circumstances shall any present or future partner of Landlord (if Landlord is a partnership), or trustee or beneficiary (if Landlord or any partner of Landlord is a
trust), have any liability for the performance of Landlord’s obligations under this Lease. Notwithstanding any contrary provision herein, neither Landlord nor the Landlord Parties shall be liable under any circumstances for injury or damage to,
or interference with, Tenant’s business, including but not limited to, loss of profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill or loss of use, in each case, however occurring, or loss to inventory,
scientific research, scientific experiments, laboratory animals, products, specimens, samples, and/or scientific, business, accounting and other records of every kind and description kept at the premises and any and all income derived or derivable
therefrom. 
 29.14    Entire Agreement. It is understood and acknowledged that there are no oral
agreements between the parties hereto affecting this Lease and this Lease constitutes the parties’ entire agreement with respect to the leasing of the Premises and supersedes and cancels any and all previous negotiations, arrangements,
brochures, agreements and understandings, if any, between the parties hereto or displayed by Landlord to Tenant with respect to the subject matter thereof, and none thereof shall be used to interpret or construe this Lease. None of the terms,
covenants, conditions or provisions of this Lease can be modified, deleted or added to except in writing signed by the parties hereto. 

29.15    Right to Lease. Landlord reserves the absolute right to effect such other tenancies in the Project
as Landlord in the exercise of its sole business judgment shall determine to best promote the interests of the Building or Project. Tenant does not rely on the fact, nor does Landlord represent, that any specific tenant or type or number of tenants
shall, during the Lease Term, occupy any space in the Building or Project. 
 29.16    Force Majeure. Any
prevention, delay or stoppage due to strikes, lockouts, labor disputes, acts of God, acts of war, terrorist acts, inability to obtain services, labor, or materials or reasonable substitutes therefor, governmental actions, civil commotions, fire or
other casualty, and other causes beyond the reasonable control of the party obligated to perform, except with respect to the obligations imposed with regard to Rent and other charges to be paid by Tenant or Landlord pursuant to this Lease
(collectively, a “Force Majeure”), notwithstanding anything to the contrary contained in this Lease, shall excuse the performance of such party for a period equal to any such prevention, delay or stoppage and, therefore, if this
Lease specifies a time period for performance of an obligation of either party, that time period shall be extended by the period of any delay in such party’s performance caused by a Force Majeure. 

29.17    Waiver of Redemption by Tenant. Tenant hereby waives, for Tenant and for all those claiming under
Tenant, any and all rights now or hereafter existing to redeem by order or judgment of any court or by any legal process or writ, Tenant’s right of occupancy of the Premises after any termination of this Lease. 

29.18    Notices. All notices, demands, statements, designations, approvals or other communications
(collectively, “Notices”) given or required to be given by either party to the other hereunder or by law shall be in writing, shall be (A) sent by United States certified or registered mail, postage prepaid, return receipt
requested (“Mail”), (B) transmitted by telecopy, if such telecopy is promptly followed by a Notice sent by Mail, (C) delivered by a nationally recognized overnight courier, or (D) delivered personally. Any Notice shall be
sent, transmitted, or delivered, as the case may be, to Tenant at the appropriate address set forth in Section 10 of the Summary, or to such other place as Tenant may from time to time designate in a Notice to Landlord, or
to Landlord at the addresses set forth below, or to such other places as Landlord may from time to time designate in a Notice to Tenant. Any Notice will be deemed given (i) three (3) days after the date it is posted if sent by Mail,
(ii) the date the telecopy is transmitted, (iii) the date the overnight courier delivery is made, or (iv) the date personal delivery is made. As of the date of this Lease, any Notices to Landlord must be sent, transmitted, or
delivered, as the case may be, to the following addresses:

29.19    Joint and Several. If there is more than one tenant, the obligations imposed upon Tenant under this
Lease shall be joint and several. 
 29.20    Authority. If Tenant is a corporation, trust or partnership,
each individual executing this Lease on behalf of Tenant hereby represents and warrants that Tenant is a duly formed and existing entity qualified to do business in the State of California and that Tenant has full right and authority to execute and
deliver this Lease and that each person signing on behalf of Tenant is authorized to do so. If requested by Landlord, Tenant shall, within ten (10) days after execution of this Lease, deliver to Landlord satisfactory evidence of such authority

MANDATORY) IN ANY SUCH PROCEEDING OR ACTION, BUT SHALL BE RELEGATED TO AN INDEPENDENT ACTION AT LAW. 

29.23    Submission of Lease. Submission of this instrument for examination or signature by Tenant does not
constitute a reservation of, option for or option to lease, and it is not effective as a lease or otherwise until execution and delivery by both Landlord and Tenant.

[Aligos Thereapeutics, Inc.]

 29.24    Brokers. Landlord and Tenant hereby warrant to
each other that they have had no dealings with any real estate broker or agent in connection with the negotiation of this Lease, excepting only the real estate brokers or agents specified in Section 12 of the Summary (the
“Brokers”), and that they know of no other real estate broker or agent who is entitled to a commission in connection with this Lease. Each party agrees to indemnify and defend the other party against and hold the other party
harmless from any and all claims, demands, losses, liabilities, lawsuits, judgments, costs and expenses (including without limitation reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be
owing on account of any dealings with any real estate broker or agent, other than the Brokers, occurring by, through, or under the indemnifying party. The terms of this Section 29.24 shall survive the expiration or earlier
termination of the Lease Term. Landlord shall pay any brokerage fee due to the Brokers in accordance with a separate agreement. 

29.25    Independent Covenants. This Lease shall be construed as though the covenants herein between
Landlord and Tenant are independent and not dependent and Tenant hereby expressly waives the benefit of any statute to the contrary and agrees that if Landlord fails to perform its obligations set forth herein, Tenant shall not be entitled to make
any repairs or perform any acts hereunder at Landlord’s expense or to any setoff of the Rent or other amounts owing hereunder against Landlord. 

29.26    Project or Building Name, Address and Signage. Landlord shall have the right at any time to change
the name and/or address of the Project or Building (in which event Landlord shall reimburse Tenant for its reasonable expenses incurred in connection with such change) and to install, affix and maintain any and all signs on the exterior and on the
interior of the Project or Building as Landlord may, in Landlord’s sole discretion, desire. Tenant shall not use the name of the Project or Building or use pictures or illustrations of the Project or Building in advertising or other publicity
or for any purpose other than as the address of the business to be conducted by Tenant in the Premises, without the prior written consent of Landlord. 

29.27    Counterparts. This Lease may be executed in counterparts with the same effect as if both parties
hereto had executed the same document. Both counterparts shall be construed together and shall constitute a single lease. 

29.28    Confidentiality. Tenant acknowledges that the content of this Lease and any related documents are
confidential information. Tenant shall keep such confidential information strictly confidential and shall not disclose such confidential information to any person or entity other than Tenant’s financial, legal, and space planning consultants.
Notwithstanding the foregoing, Landlord acknowledges that if Tenant becomes publicly held (i) Tenant will be required to include, in its reports to the Securities and Exchange Commission (the “SEC”), a description of the terms
and conditions of this Lease, and a copy of this Lease, and (ii) Tenant will not seek confidential treatment of any of the terms and conditions of this Lease, notwithstanding any provision of this Lease to the contrary. Landlord hereby consents

29.29    Development of the Project. 

29.29.1    Subdivision. Landlord reserves the right to subdivide all or a portion of the buildings and
Common Areas. Tenant agrees to execute and deliver, upon demand by Landlord and in the form requested by Landlord, any additional documents needed to conform this Lease to the circumstances resulting from a subdivision and any all maps in connection
therewith. Notwithstanding anything to the contrary set forth in this Lease, the separate ownership of any buildings and/or Common Areas by an entity other than Landlord shall not affect the calculation of Direct Expenses or Tenant’s payment of
Tenant’s Share of Direct Expenses. No such subdivision shall interfere with Tenant’s use of or access to the Premises or Tenant’s access to the parking facility or facilities which serve the Building or the Project. 

29.29.2    Construction of Property and Other Improvements. Tenant acknowledges that portions of the Project
may be under construction following Tenant’s occupancy of the Premises, and that such construction may result in levels of noise, dust, obstruction of access, etc. which are in excess of that present in a fully constructed project. Tenant
hereby waives any and all rent offsets or claims of constructive eviction which may arise in connection with such construction, so long as the same does not interfere with Tenant’s use of or access to the Premises or parking facility or
facilities which serve the Building or the Project.

[Aligos Thereapeutics, Inc.]

 29.30    No Violation. Tenant hereby warrants and
represents that neither its execution of nor performance under this Lease shall cause Tenant to be in violation of any agreement, instrument, contract, law, rule or regulation by which Tenant is bound, and Tenant shall protect, defend, indemnify and
hold Landlord harmless against any claims, demands, losses, damages, liabilities, costs and expenses, including, without limitation, reasonable attorneys’ fees and costs, arising from Tenant’s breach of this warranty and representation.

 29.31    Transportation Management. Tenant shall fully comply with all present or future programs
intended to manage parking, transportation or traffic in and around the Project and/or the Building, and in connection therewith, Tenant shall take responsible action for the transportation planning and management of all employees located at the
Premises by working directly with Landlord, any governmental transportation management organization or any other transportation-related committees or entities. Such programs may include, without limitation: (i) restrictions on the number of
peak-hour vehicle trips generated by Tenant; (ii) increased vehicle occupancy; (iii) implementation of an in-house ridesharing program and an employee transportation coordinator; (iv) working
with employees and any Project, Building or area-wide ridesharing program manager; (v) instituting employer-sponsored incentives (financial or in-kind) to encourage employees to rideshare; and

 (l)    Unavoidable Delays: Delays due to acts of God, acts of public agencies,

Landlord or Tenant, as applicable. 
 (m)    Capitalized terms not otherwise defined in this Tenant Work Letter shall
have the definitions set forth in the Lease. 
 2.    Plans and Construction. Landlord and Tenant shall
comply with the procedures set forth in this Paragraph 2 in preparing, delivering and approving matters relating to the Tenant Improvements. 

(a)    Approved Plans and Working Drawings for Landlord’s TI Work. Landlord’s Architect and
project manager has prepared, and Landlord and Tenant have approved, preliminary plans and specifications and a scope of work for the Premises. The most recent mutually approved version of such preliminary plans and specifications and scope of work
(the “Landlord’s Preliminary Plan”) is attached hereto as Schedule 1 and incorporated herein by this reference. Any items listed on the Landlord’s Preliminary Plan as being “alternates” or “tenant
items”, or “tenant furnished” or “tenant installed” shall be provided, if at all, by Tenant at Tenant’s sole cost and expense, and Landlord shall have no obligations with respect thereto. Landlord shall prepare or cause
to be prepared (assuming timely delivery by Tenant of all information and decisions reasonably required to be furnished or made by Tenant in order to permit preparation of Landlord’s Final Working Drawings, and subject to Tenant Delays and
Unavoidable Delays), final detailed working drawings and specifications for the Tenant Improvements constituting Landlord’s TI Work, including (as applicable) structural, fire protection, life safety, mechanical and electrical working drawings
and final architectural drawings (collectively, “Landlord’s Final Working Drawings”). Landlord’s Final Working Drawings shall be based on and consistent with the Landlord’s Preliminary Plan in all material respects
(except as otherwise mutually approved by the parties in their respective discretion). Landlord shall deliver copies of Landlord’s Final Working Drawings to Tenant for Tenant’s approval and information, and to assist Tenant in preparing
plans, specifications and drawings for Tenant’s Work as hereinafter set forth. Tenant shall promptly and diligently either approve the proposed Landlord’s Final Working Drawings, or set forth in writing with particularity any changes
necessary to bring the aspects of such proposed plans and specifications or proposed Landlord’s Final Working Drawings into a form which will be reasonably acceptable to Tenant. Notwithstanding any other provisions of this paragraph, in no
event shall Tenant have the right to object to any aspect of the Landlord’s Final Working Drawings (including, but not limited to, any subsequently proposed changes therein from time to time) that is (i) materially consistent with the
Landlord’s Preliminary Plan, (ii) necessitated by applicable law or as a condition of any governmental or other third-party approvals or consents that are required to be obtained in connection with Landlord’s TI Work, or
(iii) that is required as a result of unanticipated conditions encountered in the course of construction of Landlord’s TI Work, but to the extent Tenant identifies to Landlord any concerns arising out of any such requirements or conditions
described in this sentence, Landlord and Tenant shall cooperate reasonably, diligently and in good faith to discuss possible changes in the nature or scope of the Tenant Improvements that might minimize or avoid the effects of such requirements or
conditions. Failure of Tenant to deliver to Landlord written notice of disapproval and specification of required changes on or before any deadline reasonably specified by Landlord (which shall not be less than five (5) days after delivery
thereof to Tenant) in delivering an applicable set of plans, specifications and/or drawings to Tenant shall constitute and be deemed to be approval of Landlord’s proposed plans and specifications or proposed Landlord’s Final Working
Drawings, as applicable.

 (b)    Construction of Landlord’s TI Work. Following
completion of Landlord’s Final Working Drawings, Landlord shall apply for and use reasonable efforts to obtain the necessary permits and approvals to allow construction of all Tenant Improvements constituting Landlord’s TI Work. Upon
receipt of such permits and approvals, Landlord shall, at Landlord’s expense (subject to Tenant’s obligations to pay for the cost of any Tenant required changes to the Landlord’s Preliminary Plan or Landlord’s Final Working
Drawings or any costs in excess of the “Tenant Improvement Allowance” as defined in Section 4 below), construct and complete the Tenant Improvements constituting Landlord’s TI Work substantially in
accordance with the Landlord’s Final Working Drawings, subject to Unavoidable Delays and Tenant Delays (if any). Such construction shall be performed in a neat, good and workmanlike manner, free from defects, using new materials and equipment
of good quality, and shall materially conform to all applicable laws, rules, regulations, codes, ordinances, requirements, covenants, conditions and restrictions applicable thereto in force at the time such work is completed. The Premises will be
constructed in multiple phases as defined by Architect and Contractor during the development of the Final Working Drawings, and Tenant will commence to occupy the initial phase after its completion, and prior to the completion of construction in the
second phase. The first phase shall generally consist of work outside of the Early Occupancy Space and associated spaces that cannot be demolished or modified while Tenant is in occupancy of such Early Occupancy Space. The second phase will consist
of work not included in the first phase, to be completed after Tenant has vacated the Early Occupancy Space. 

(c)    Changes. 

(i)    If Landlord determines at any time that changes in Landlord’s Final Working Drawings or in any
other aspect of the Landlord’s Approved Plans relating to any item of Landlord’s TI Work are required as a result of applicable law or governmental requirements, or are required as a result of unanticipated conditions encountered in the
course of construction, then Landlord shall promptly (A) advise Tenant of such circumstances and (B) at Landlord’s sole cost and expense, cause revised Landlord’s Final Working Drawings to be prepared by Landlord’s Architect
and submitted to Tenant, for Tenant’s information and approval, not to be unreasonably withheld. 

(ii)    If Tenant at any time desires any changes, alterations or additions to the Landlord’s Final
Working Drawings with respect to any of Landlord’s TI Work, Tenant shall submit a detailed written request to Landlord specifying such changes, alterations or additions (a “Tenant Change Request”). Upon receipt of any such
request, Landlord shall promptly notify Tenant of (A) whether the matters proposed in the Tenant Change Request are approved by Landlord (which approval shall not be unreasonably withheld, conditioned or delayed by Landlord), (B)
Landlord’s estimate of the number of days of delay, if any, which shall be caused in Landlord’s TI Work by such Tenant Change Request if implemented (including, without limitation, delays due to the need to obtain any revised plans or
drawings and any governmental approvals), and (C) Landlord’s estimate of the increase, if any, which shall occur in the cost of construction of the Landlord’s TI Work affected by such Tenant Change Request if such Tenant Change
Request is implemented (including, but not limited to, any costs of compliance with laws or governmental regulations that become applicable because of the implementation of the Tenant Change Request). If Landlord approves the Tenant Change Request
and Tenant notifies Landlord in writing, within three (3) business days after receipt of such notice from Landlord, of Tenant’s approval of the Tenant Change Request (including the estimated delays and cost increases, if any, described in
Landlord’s notice), then Landlord shall cause such Tenant Change Request to be implemented and Tenant shall be responsible for all actual costs or cost increases resulting from or attributable to the implementation of the Tenant Change Request,
and any delays resulting therefrom shall be deemed to be a Tenant Delay. If Tenant fails to notify Landlord in writing of Tenant’s approval of such Tenant Change Request within said three (3) business day period, then such Tenant Change
Request shall be deemed to be withdrawn and shall be of no further effect. 
 (d)    Project Management.
Unless and until revoked by Landlord by written notice delivered to Tenant, Landlord hereby (i) delegates to Project Manager the authority to exercise all approval rights, supervisory rights and other rights or powers of Landlord under this
Tenant Work Letter with respect to the design and construction of the Tenant Improvements, and (ii) requests that Tenant work with Project Manager with respect to any logistical or other coordination matters arising in the course of
construction of the Tenant Improvements, including monitoring Tenant’s compliance with its obligations under this Tenant Work Letter and under the Lease with respect to the design and construction of the Tenant Improvements. Tenant acknowledges
the foregoing delegation and request, and agrees 

  

					
		 	 EXHIBIT B

-3-
	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
to cooperate reasonably with Project Manager as Landlord’s representative pursuant to such delegation and request. Fees and charges of Project Manager for such services shall be at
Tenant’s sole expense, subject to Landlord’s payment of the Tenant Improvement Allowance. Such fees shall be equal to 2.9% of all funds the Tenant Improvement Allowance or Additional Tenant Improvement Allowance used in connection with the
construction of the Tenant Improvements, and 2% of any additional funds provided by Tenant for such construction. Such fees are initially estimated based on the total contract price and paid in equal monthly installments over the duration of the
project. 
 3.    Completion. 

(a)    When Landlord receives written certification from Architect that construction of the Tenant Improvements
constituting Landlord’s TI Work in the Building for each phase of the Premises has been completed in accordance with the Landlord’s Approved Plans (except for Punch List Work), Landlord shall prepare and deliver to Tenant a certificate
signed by both Landlord and Architect (the “Substantial Completion Certificate”) (i) certifying that the construction of the Tenant Improvements constituting Landlord’s TI Work in the Building for such phase of the Premises has
been substantially completed in a good and workmanlike manner in accordance with the Landlord’s Approved Plans in all material respects, subject only to completion of Punch List Work, and specifying the date of that completion, and
(ii) certifying that Landlord’s TI Work complies in all material respects with all laws, rules, regulations, codes, ordinances, requirements, covenants, conditions and restrictions applicable thereto at the time of such delivery, including
the ADA and all building codes. Upon receipt by Tenant of the Substantial Completion Certificate and tender of possession of each phase of the Premises by Landlord to Tenant, and receipt of any certificate of occupancy or its legal equivalent, or
other required sign-offs from any applicable governmental authority, allowing the legal occupancy of the Premises, the Tenant Improvements constituting Landlord’s TI Work in the Building will be deemed delivered to Tenant and “Ready for
Occupancy” for all purposes of the Lease with respect to such phase of the Premises (subject to Landlord’s continuing obligations with respect to any Punch List Work, and to any other express obligations of Landlord under the Lease or this
Tenant Work Letter with respect to such Tenant Improvements). 
 (b)    Promptly following delivery of the Substantial
Completion Certificate for Landlord’s TI Work in the Building, Project Manager or other representatives of Landlord shall conduct one or more “walkthroughs” of the Building with Tenant and Tenant’s representatives, to identify
any items of Punch List Work that may require correction and to prepare a joint punch list reflecting any such items, following which Landlord shall diligently complete the Punch List Work reflected in such joint punch list. At any time within
thirty (30) days after delivery of such Substantial Completion Certificate with respect to each phase of the Premises, Tenant shall be entitled to submit one or more lists to Landlord supplementing such joint punch list by specifying any
additional items of Punch List Work to be performed on the applicable Tenant Improvements constituting Landlord’s TI Work in the Building, and upon receipt of such list(s), Landlord shall diligently complete such additional Punch List Work.
Promptly after Landlord provides Tenant with the Substantial Completion Certificate and completes all applicable Punch List Work for the Building, Landlord shall cause the recordation of a Notice of Completion (as defined in Section 3093 of the
California Civil Code or applicable successor statute) with respect to Landlord’s TI Work in the Building. 

(c)    All construction, product and equipment warranties and guaranties obtained by Landlord with respect to
Landlord’s TI Work shall, to the extent reasonably obtainable, include a provision that such warranties and guaranties shall also run to the benefit of Tenant, and Landlord shall cooperate with Tenant in a commercially reasonable manner to
assist in enforcing all such warranties and guaranties for the benefit of Tenant. 
 (d)    Notwithstanding any other
provisions of this Tenant Work Letter or of the Lease, if Landlord is delayed in substantially completing any of Landlord’s TI Work as a result of any Tenant Delay, and if the Rent Commencement Date is being determined under clause (ii) of
Section 3.2 of the Lease Summary, then notwithstanding any other provisions of the Lease to the contrary, the Premises shall be deemed to have been Ready for Occupancy on the date the Premises would have been Ready for Occupancy absent such
Tenant Delay. 
 4.    Payment of Costs. 

(a)    Tenant Improvement Allowance. Subject to any restrictions, conditions or limitations expressly set
forth in this Tenant Work Letter or in the Lease or as otherwise expressly provided by mutual written agreement of Landlord and Tenant, the cost of construction of the Tenant Improvements shall be paid or reimbursed

  

					
		 	 EXHIBIT B

-4-
	 	 [Britannia Gateway Business Park]
  

[Aligos Thereapeutics, Inc.]

 
by Landlord up to a maximum amount as set forth in Section 5 of the Summary to the Lease (the “Tenant Improvement Allowance”), which amount is being
made available by Landlord to be applied towards the Cost of Improvements for the construction of the Tenant Improvements in the Premises. Tenant shall be responsible, at its sole cost and expense, for payment of the entire cost of construction
(including all design and permit and other associated costs) (collectively, the “Cost of Improvements”) of the Tenant Improvements in excess of the Tenant Improvement Allowance, including (but not limited to) any costs or cost
increases incurred as a result of delays (unless caused by Landlord), governmental requirements or unanticipated conditions (unless caused by Landlord), and for payment of any and all costs and expenses relating to any alterations, additions,
improvements, furniture, furnishings, equipment, fixtures and personal property items which are not eligible for application of Tenant Improvement Allowance funds under the restrictions expressly set forth below in this paragraph, but Tenant shall
be entitled to use or apply the entire Tenant Improvement Allowance toward the Cost of Improvements of the Tenant Improvements (subject to any applicable restrictions, conditions, limitations, reductions or charges set forth in the Lease or in this
Tenant Work Letter) prior to being required to expend any of Tenant’s own funds for the Tenant Improvements. The funding of the Tenant Improvement Allowance shall be made on a monthly basis or at other convenient intervals mutually approved by
Landlord and Tenant and in all other respects shall be based on such commercially reasonable disbursement conditions and procedures as Landlord, Project Manager and Landlord’s lender (if any) may reasonably prescribe. Notwithstanding the
foregoing provisions, under no circumstances shall the Tenant Improvement Allowance or any portion thereof be used or useable by Tenant for any moving or relocation expenses of Tenant, or for any Cost of Improvement (or any other cost or expense)
associated with any moveable furniture or trade fixtures, personal property or any other item or element which, under the applicable provisions of the Lease, will not become Landlord’s property and remain with the Building upon expiration or
termination of the Lease. Notwithstanding anything to the contrary herein, the Tenant Improvements shall not include (and Landlord shall be solely responsible for and the Tenant Improvement Allowance shall not be used for) the following:
(a) costs incurred due to the presence of any Hazardous Materials in the Premises, if any; (b) costs to bring the Project into compliance with Applicable Laws to the extent required in order to allow Tenant to obtain a certificate of
occupancy or its legal equivalent, for the Premises for the Permitted Use assuming a normal and customary office occupancy density; (c) construction costs in excess of the contract amount stated in the contract with the General Contractor, as
approved by Tenant (not to be unreasonably withheld), except for increases set forth in change orders approved by Tenant; (d) wages, labor and overhead for overtime and premium time unless approved by Tenant (which approval shall not be
unreasonably withheld, conditioned or delayed); (e) attorneys’ fees incurred in connection with negotiation of construction contracts, and attorneys’ fees, experts’ fees and other costs in connection with disputes with third parties;
(f) interest and other costs of financing construction costs; (g) costs incurred as a consequence construction defects or default by a contractor; (h) costs as a consequence of casualties; and (i) penalties and late charges
attributable to Landlord’s failure to pay construction costs. Tenant shall use at least twenty percent (20%) of the Tenant Improvement Allowance prior to December 31, 2019, and the remainder prior to December 31, 2021. Any amounts not
so expended shall revert to Landlord and Tenant shall have no further rights with respect thereto. 

(b)    Tenant Funds. Any additional funds required to complete the cost of the work, that are in excess
of or elected by the Tenant to be used from the Tenant Improvement Allowance, shall be considered “Tenant Funds”. Tenant acknowledges that an estimate of the required Tenant Funds will be determined at the time Landlord enters
into the agreed upon Guaranteed Maximum Price construction contract (“GMP”) and establishes the Project Budget. Tenant further acknowledges that such amount is an estimate and exact costs will not be known until project
closeout. Tenant shall be required, on a monthly progress payment basis, to pay a percentage of each required payment to the contractor under the GMP, based on the ratio between the amount of the Tenant Funds and the total estimated cost of the
work. 
 5.    No Agency. Nothing contained in this Tenant Work Letter shall make or constitute Tenant as
the agent of Landlord. 
 6.    Tenant Access. Provided that Tenant and its agents do not interfere with
Contractor’s work in the Building and the Premises, Contractor shall allow Tenant access to the Premises without payment of Rent at least thirty (30) days prior to the Substantial Completion of the Landlord’s TI Work for the purpose
of Tenant installing equipment or fixtures (including Tenant’s data and telephone equipment) in the Premises and for the purpose of preparing to do business. Prior to Tenant’s entry into the Premises as permitted by the terms of this
Section 6, Tenant shall submit a schedule to Landlord and Contractor, for their approval, which schedule shall detail the timing and purpose of Tenant’s entry. Tenant shall hold Landlord harmless from and indemnify,
protect and defend Landlord against any loss or damage to the Building or Premises and against injury to any persons caused by Tenant’s actions pursuant to this Section 6.

 7.    Miscellaneous. All references in this Tenant Work
Letter to a number of days shall be construed to refer to calendar days, unless otherwise specified herein. In all instances where Landlord’s or Tenant’s approval is required, if no written notice of disapproval is given within the
applicable time period, at the end of that period Landlord or Tenant shall be deemed to have given approval (unless the provision requiring Landlord’s or Tenant’s approval expressly states that
non-response is deemed to be a disapproval or withdrawal of the pending action or request, in which event such express statement shall be controlling over the general statement set forth in this sentence) and
the next succeeding time period shall commence. If any item requiring approval is disapproved by Landlord or Tenant (as applicable) in a timely manner, the procedure for preparation of that item and approval shall be repeated.

FORM OF TENANT’S ESTOPPEL CERTIFICATE

dioxide and inert simple asphyxiant gases, which have a higher trigger limit of 3 1,000 cubic feet); 3
55 gallons if any one type of hazardous chemical liquid; and 3500 pounds of any one type of hazardous chemical solid. So a full-sixe gas cylinder and a 260-liter of liquid nitrogen are triggers! Don’t forget the diesel fuel in a backup emergency generator if the diesel tank size is 3 55
gallons and it is permitted under the tenant (rather than under the landlord).] NOTE: Each local Certified Unified Program Agency (CUPA) in California governs the HMBP process so start there. Examples: the CUPA for cities in San Mateo County is
the County Environmental Health Department; the CUPA for the City of Hayward, CA is the Hayward Fire Department; the CUPA for Mountain View is the Mountain View Fire Department; and, the CUPA for San Diego is the County of San Diego Hazardous
Materials Division (HMD), 

 ☐ Yes    ☐ No, not required. ☐ No, but one will be
prepared and submitted, and a copy will be provided to the landlord property management company.

 If one has been completed, please attach a copy. Continue to provide updated versions as
they are completed. This is a legal requirement in that State law requires that the owner/operator of a business located on leased or rented real property shall notify, in writing, the owner of the property that the business is subject to and is in
compliance with the Hazardous Materials Business Plan requirements (Health and Safety Code Chapter 6.95 Section 25505.1). 
  

	 	7-3.	 NOTE: Please be advised that if you are involved in any tenant improvements that require a construction
permit, you will be asked to provide the local city with a Hazardous Materials Inventory Statement (HMIS) to ensure that your hazardous chemicals fall within the applicable Fire Code fire control area limits for the applicable construction occupancy
of the particular building. The HMIS will include much of the information listed in Section 2-2. Neither the landlord nor the landlord’s property management company expressly warrants that the
inventory provided in Section 2-2 will necessarily meet the applicable California Fire Code fire control area limits for building occupancy, especially in shared tenant occupancy situations. It is the
responsibility of the tenant to ensure that a facility and site can legally handle the intended operations and hazardous materials desired/ needed for its operations, but the landlord is happy to assist in this determination when possible.

 Exhibit 10.5(a) 

ALIGOS THERAPEUTICS, INC. 

2018 EQUITY INCENTIVE PLAN, AS AMENDED 

1.    Purpose. The purpose of the Plan is to advance the interests of the Company’s stockholders by enhancing
the Company’s ability to attract, retain and motivate persons who make (or are expected to make) important contributions to the Company by providing such persons with equity ownership opportunities and thereby better aligning the interests of
such persons with those of the Company’s stockholders. Capitalized terms used in the Plan are defined in Section 11 below. 

2.    Eligibility. Service Providers are eligible to be granted Awards under the Plan, subject to the limitations
described herein. 
 3.    Administration and Delegation.  

3.1    Administration. The Plan will be administered by the Administrator. The Administrator shall have
authority to determine which Service Providers will receive Awards, to grant Awards and to set all terms and conditions of Awards (including, but not limited to, vesting, exercise and forfeiture provisions). In addition, the Administrator shall have
the authority to take all actions and make all determinations contemplated by the Plan and to adopt, amend and repeal such administrative rules, guidelines and practices relating to the Plan as it shall deem advisable. The Administrator may correct
any defect or ambiguity, supply any omission or reconcile any inconsistency in the Plan or any Award in the manner and to the extent it shall deem necessary or appropriate to carry the Plan and any Awards into effect, as determined by the
Administrator. The Administrator shall make all determinations under the Plan in the Administrator’s sole discretion and all such determinations shall be final and binding on all persons having or claiming any interest in the Plan or in any
Award. 
 3.2    Appointment of Committees. To the extent permitted by Applicable Laws, the Board may
delegate any or all of its powers under the Plan to one or more Committees. The Board may abolish any Committee at any time and re-vest in itself any previously delegated authority. 

4.    Stock Available for Awards. 

4.1    Number of Shares. Subject to adjustment under Section 8 hereof, Awards may be made under the
Plan covering up to 45,793,887 shares of Common Stock. If any Award expires or lapses or is terminated, surrendered or canceled without having been fully exercised or is forfeited in whole or in part (including as the result of shares of Common
Stock subject to such Award being repurchased by the Company at or below the original issuance price), in any case in a manner that results in any shares of Common Stock covered by such Award not being issued or being so reacquired by the Company,
the unused Common Stock covered by such Award shall again be available for the grant of Awards under the Plan. Further, shares of Common Stock delivered (either by actual delivery or attestation) to the Company by a Participant to satisfy the
applicable exercise or purchase price of an Award and/or to satisfy any applicable tax withholding obligation (including shares retained by the Company from the Award being 

 
exercised or purchased and/or creating the tax obligation) shall be added to the number of shares of Common Stock available for the grant of Awards under the Plan. However, in the case of
Incentive Stock Options, the foregoing provisions shall be subject to any limitations under the Code. Shares of Common Stock issued under the Plan may consist in whole or in part of authorized but unissued shares, shares purchased on the open market
or treasury shares. 
 4.2    Substitute Awards. In connection with a merger or consolidation of an entity with
the Company or the acquisition by the Company of property or stock of an entity, the Administrator may grant Awards in substitution for any options or other stock or stock-based awards granted prior to such merger or consolidation by such entity or
an affiliate thereof. Substitute Awards may be granted on such terms as the Administrator deems appropriate in the circumstances, notwithstanding any limitations on Awards contained in the Plan. Substitute Awards shall not count against the overall
share limit set forth in Section 4.1 hereof, except as may be required by reason of Section 422 of the Code. 

5.    Stock Options.  

5.1    General. The Administrator may grant Options to any Service Provider, subject to the limitations on
Incentive Stock Options described below. The Administrator shall determine the number of shares of Common Stock to be covered by each Option, the exercise price of each Option and the conditions and limitations applicable to the exercise of each
Option, including conditions relating to Applicable Laws, as it considers necessary or advisable. 
 5.2    Incentive
Stock Options. The Administrator may grant Options intended to qualify as Incentive Stock Options only to employees of the Company, any of the Company’s present or future “parent corporations” or “subsidiary
corporations” as defined in Sections 424(e) or (f) of the Code, respectively, and any other entities the employees of which are eligible to receive Incentive Stock Options under the Code. All Options intended to qualify as Incentive Stock
Options shall be subject to and shall be construed consistently with the requirements of Section 422 of the Code. Neither the Company nor the Administrator shall have any liability to a Participant, or any other party, (i) if an Option (or
any part thereof) which is intended to qualify as an Incentive Stock Option fails to qualify as an Incentive Stock Option or (ii) for any action or omission by the Administrator that causes an Option not to qualify as an Incentive Stock Option,
including without limitation, the conversion of an Incentive Stock Option to a Non-Qualified Stock Option or the grant of an Option intended as an Incentive Stock Option that fails to satisfy the requirements
under the Code applicable to an Incentive Stock Option. Any Option that is intended to qualify as an Incentive Stock Option, but fails to so qualify for any reason, including without limitation, the portion of any Option becoming exercisable in
excess of the $100,000 limitation described in Treasury Regulation Section 1.422-4, shall be treated as a Non-Qualified Stock Option for all purposes. 

5.3    Exercise Price. The Administrator shall establish the exercise price of each Option and specify the
exercise price in the applicable Award Agreement. The exercise price shall be not less than 100% of the Fair Market Value on the date the Option is granted. In the case of an Incentive Stock Option granted to an employee who, at the time of grant of
the Option, owns (or is treated as owning under Section 424 of the Code) stock representing more than 10% of the voting power of all classes of stock of the Company (or a “parent corporation”

  
 2 

 
or “subsidiary corporation” thereof within the meaning of Sections 424(e) or 424(f) of the Code, respectively), the per share exercise price shall be no less than 110% of the Fair
Market Value on the date the Option is granted. 
 5.4    Duration of Options. Each Option shall be
exercisable at such times and subject to such terms and conditions as the Administrator may specify in the applicable Award Agreement, provided that the term of any Option shall not exceed ten years. In the case of an Incentive Stock Option granted
to an employee who, at the time of grant of the Option, owns (or is treated as owning under Section 424 of the Code) stock representing more than 10% of the voting power of all classes of stock of the Company (or a “parent
corporation” or “subsidiary corporation” thereof within the meaning of Sections 424(e) or 424(f) of the Code, respectively), the term of the Option shall not exceed five years. 

5.5    Exercise of Option; Notification of Disposition. Options may be exercised by delivery to the Company
of a written notice of exercise, in a form approved by the Administrator (which may be an electronic form), signed by the person authorized to exercise the Option, together with payment in full (i) as specified in Section 5.6 hereof for
the number of shares for which the Option is exercised and (ii) as specified in Section 9.5 hereof for any applicable withholding taxes. Unless otherwise determined by the Administrator, an Option may not be exercised for a fraction of a
share of Common Stock. If an Option is designated as an Incentive Stock Option, the Participant shall give prompt notice to the Company of any disposition or other transfer of any shares of Common Stock acquired from the Option if such disposition
or transfer is made (i) within two years from the grant date with respect to such Option or (ii) within one year after the transfer of such shares to the Participant (other than any such disposition made in connection with a Change in
Control). Such notice shall specify the date of such disposition or other transfer and the amount realized, in cash, other property, assumption of indebtedness or other consideration, by the Participant in such disposition or other transfer. 

5.6    Payment Upon Exercise. Common Stock purchased upon the exercise of an Option granted under the Plan
shall be paid for in cash or by check, payable to the order of the Company, or, to the extent permitted by the Administrator, by: 

(a)    (A) delivery of an irrevocable and unconditional undertaking by a broker acceptable to the Company to deliver
promptly to the Company sufficient funds to pay the exercise price and any required tax withholding, or (B) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the Company
to deliver promptly to the Company cash or a check sufficient to pay the exercise price and any required tax withholding; 

(b)    delivery (either by actual delivery or attestation) of shares of Common Stock owned by the Participant valued at
their Fair Market Value, provided (A) such method of payment is then permitted under Applicable Laws, (B) such Common Stock, if acquired directly from the Company, was owned by the Participant for such minimum period of time, if any, as
may be established by the Company at any time, and (C) such Common Stock is not subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements; 

  
 3 

 (c)    surrendering shares of Common Stock then issuable upon exercise
of the Option valued at their Fair Market Value on the date of exercise; 
 (d)    delivery of a promissory note of the
Participant to the Company on terms determined by the Administrator; 
 (e)    delivery of property of any other kind
which constitutes good and valuable consideration as determined by the Administrator; or 
 (f)    any combination of
the above permitted forms of payment (including cash or check). 
 5.7    Early Exercise of Options. The
Administrator may provide in the terms of an Award Agreement that the Service Provider may exercise an Option in whole or in part prior to the full vesting of the Option in exchange for unvested shares of Restricted Stock with respect to any
unvested portion of the Option so exercised. Shares of Restricted Stock acquired upon the exercise of any unvested portion of an Option shall be subject to such terms and conditions as the Administrator shall determine. 

6.    Restricted Stock; Restricted Stock Units. 

6.1    General. The Administrator may grant Restricted Stock, or the right to purchase Restricted Stock, to any
Service Provider, subject to the right of the Company to repurchase all or part of such shares at their issue price or other stated or formula price from the Participant (or to require forfeiture of such shares if issued at no cost) in the event
that conditions specified by the Administrator in the applicable Award Agreement are not satisfied prior to the end of the applicable restriction period or periods established by the Administrator for such Award. In addition, the Administrator may
grant to Service Providers Restricted Stock Units, which may be subject to vesting and forfeiture conditions during applicable restriction period or periods, as set forth in an applicable Award Agreement. 

6.2     Terms and Conditions for All Restricted Stock and Restricted Stock Unit Awards. The Administrator
shall determine and set forth in the applicable Award Agreement the terms and conditions applicable to each Restricted Stock and Restricted Stock Unit Award, including the conditions for vesting and repurchase (or forfeiture) and the issue price, in
each case, if any.
 6.3    Additional Provisions Relating to Restricted Stock.

(a)    Dividends. Participants holding shares of Restricted Stock will be entitled to all ordinary cash dividends
paid with respect to such shares to the extent such dividends have a record date that is on or after the date on which the Participant to whom such Restricted Shares are granted becomes the record holder of such Restricted Shares, unless otherwise
provided by the Administrator in the applicable Award Agreement. In addition, unless otherwise provided by the Administrator, if any dividends or distributions are paid in shares, or consist of a dividend or distribution to holders of Common Stock
of property other than an ordinary cash dividend, the shares or other property will be subject to the same restrictions on transferability and forfeitability as the shares of Restricted Stock with respect to which they were

  
 4 

 
paid. Each dividend payment will be made as provided in the applicable Award Agreement, but in no event later than the end of the calendar year in which the dividends are paid to stockholders of
that class of stock or, if later, the 15th day of the third month following the later of (A) the date the dividends are paid to stockholders of that class of stock, and (B) the date the dividends are no longer subject to forfeiture. 

(b)    Stock Certificates. The Company may require that any stock certificates issued in respect of shares of
Restricted Stock be deposited in escrow by the Participant, together with a stock power endorsed in blank, with the Company (or its designee). 

6.4    Additional Provisions Relating to Restricted Stock Units. 

(a)    Settlement. Upon the vesting of a Restricted Stock Unit, the Participant shall be entitled to receive from
the Company one share of Common Stock or an amount of cash or other property equal to the Fair Market Value of one share of Common Stock on the settlement date, as the Administrator shall determine and as provided in the applicable Award Agreement.
The Administrator may provide that settlement of Restricted Stock Units shall occur upon or as soon as reasonably practicable after the vesting of the Restricted Stock Units or shall instead be deferred, on a mandatory basis or at the election of
the Participant, in a manner that complies with Section 409A.
 (b)    Voting Rights. A Participant shall
have no voting rights with respect to any Restricted Stock Units unless and until shares are delivered in settlement thereof.

(c)    Dividend Equivalents. To the extent provided by the Administrator, a grant of Restricted Stock Units may
provide a Participant with the right to receive Dividend Equivalents. Dividend Equivalents may be paid currently or credited to an account for the Participant, may be settled in cash and/or shares of Common Stock and may be subject to the same
restrictions on transfer and forfeitability as the Restricted Stock Units with respect to which the Dividend Equivalents are paid, as determined by the Administrator, subject, in each case, to such terms and conditions as the Administrator shall
establish and set forth in the applicable Award Agreement. 

  
 5 

 7.    Other Stock-Based Awards.  

Other Stock-Based Awards may be granted hereunder to Participants, including, without limitation, Awards entitling Participants to receive
shares of Common Stock to be delivered in the future. Such Other Stock-Based Awards shall also be available as a form of payment in the settlement of other Awards granted under the Plan, as stand-alone payments and/or as payment in lieu of
compensation to which a Participant is otherwise entitled. Other Stock-Based Awards may be paid in shares of Common Stock, cash or other property, as the Administrator shall determine. Subject to the provisions of the Plan, the Administrator shall
determine the terms and conditions of each Other Stock-Based Award, including any purchase price, transfer restrictions, vesting conditions and other terms and conditions applicable thereto, which shall be set forth in the applicable Award
Agreement. 
 8.    Adjustments for Changes in Common Stock and Certain Other Events. 

8.1    In the event that the Administrator determines that any dividend or other distribution (whether in the form of
cash, Common Stock, other securities, or other property), reorganization, merger, consolidation, combination, repurchase, recapitalization, liquidation, dissolution, or sale, transfer, exchange or other disposition of all or substantially all of the
assets of the Company, or sale or exchange of Common Stock or other securities of the Company, issuance of warrants or other rights to purchase Common Stock or other securities of the Company, or other similar corporate transaction or event, as
determined by the Administrator, affects the Common Stock such that an adjustment is determined by the Administrator to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended by the Company to be
made available under the Plan or with respect to any Award, then the Administrator may, in such manner as it may deem equitable, adjust any or all of: 

(a)    the number and kind of shares of Common Stock (or other securities or property) with respect to which Awards may be
granted or awarded (including, but not limited to, adjustments of the limitations in Section 4 hereof on the maximum number and kind of shares which may be issued); 

(b)    the number and kind of shares of Common Stock (or other securities or property) subject to outstanding Awards;

 (c)    the grant or exercise price with respect to any Award; and 

(d)    the terms and conditions of any Awards (including, without limitation, any applicable financial or other
performance “targets” specified in an Award Agreement). 
 8.2    In the event of any transaction or event
described in Section 8.1 hereof (including without limitation any Change in Control) or any unusual or nonrecurring transaction or event affecting the Company or the financial statements of the Company, or any change in any Applicable Laws or
accounting principles, the Administrator, on such terms and conditions as it deems appropriate, either by the terms of the Award or by action taken prior to the occurrence of such transaction or event and either automatically or upon the
Participant’s request, is hereby authorized to take any one or more of the following actions whenever the Administrator 

  
 6 

 
determines that such action is appropriate in order to (x) prevent dilution or enlargement of the benefits or potential benefits intended by the Company to be made available under the Plan
or with respect to any Award granted or issued under the Plan, (y) to facilitate such transaction or event or (z) give effect to such changes in Applicable Laws or accounting principles:  

(a)    To provide for the cancellation of any such Award in exchange for either an amount of cash or other property with a
value equal to the amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s rights under the vested portion of such Award, as applicable; provided that, if the
amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s rights, in any case, is equal to or less than zero, then the vested portion of such Award may be
terminated without payment; 
 (b)    To provide that such Award shall vest and, to the extent applicable, be
exercisable as to all shares covered thereby, notwithstanding anything to the contrary in the Plan or the provisions of such Award; 

(c)    To provide that such Award be assumed by the successor or survivor corporation, or a parent or subsidiary thereof,
or shall be substituted for by awards covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and applicable exercise or purchase price, in all
cases, as determined by the Administrator; 
 (d)    To make adjustments in the number and type of shares of Common
Stock (or other securities or property) subject to outstanding Awards, and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding Awards which may be granted in the future; 

(e)    To replace such Award with other rights or property selected by the Administrator; or 

(f)    To provide that the Award will terminate and cannot vest, be exercised or become payable after the applicable
event. 
 8.3    Notwithstanding the provisions of Section 8.2 above, if a Change in Control occurs and a
Participant’s Awards are not continued, converted, assumed, or replaced with a substantially similar award by (i) the Company, or (ii) a successor entity or its parent or subsidiary (an “Assumption”), and
provided that the Participant has not had a Termination of Service, then immediately prior to the Change in Control such Awards shall become fully vested, exercisable and/or payable, as applicable, and all forfeiture, repurchase and other
restrictions on such Awards shall lapse, in which case, such Awards shall be canceled upon the consummation of the Change in Control in exchange for the right to receive the Change in Control consideration payable to other holders of Common Stock
(A) which may be on such terms and conditions as apply generally to holders of Common Stock under the Change in Control documents (including, without limitation, any escrow, earn-out or other deferred
consideration provisions) or such other terms and conditions as the Administrator may provide, and (B) determined by reference to the number of shares subject to such Awards and net of any applicable exercise price; provided that

  
 7 

 
to the extent that any Awards constitute “nonqualified deferred compensation” that may not be paid upon the Change in Control under Section 409A without the imposition of taxes
thereon under Section 409A, the timing of such payments shall be governed by the applicable Award Agreement (subject to any deferred consideration provisions applicable under the Change in Control documents); and provided, further, that if the
amount to which a Participant would be entitled upon the settlement or exercise of such Award at the time of the Change in Control is equal to or less than zero, then such Award may be terminated without payment. The Administrator shall determine
whether an Assumption of an Award has occurred in connection with a Change in Control. 
 8.4    In connection with the
occurrence of any Equity Restructuring, and notwithstanding anything to the contrary in this Section 8, the Administrator will equitably adjust each outstanding Award, which adjustments may include adjustments to the number and type of
securities subject to each outstanding Award and/or the exercise price or grant price thereof, if applicable, the grant of new Awards to Participants, and/or the making of a cash payment to Participants, as the Administrator deems appropriate to
reflect such Equity Restructuring. The adjustments provided under this Section 8.4 shall be nondiscretionary and shall be final and binding on the affected Participant and the Company; provided that whether an adjustment is equitable shall be
determined by the Administrator. 
 8.5    In the event of any pending stock dividend, stock split, combination or
exchange of shares, merger, consolidation or other distribution (other than normal cash dividends) of Company assets to stockholders, or any other change affecting the shares of Common Stock or the share price of the Common Stock, including any
Equity Restructuring, for reasons of administrative convenience the Administrator may refuse to permit the exercise of any Award during a period of up to 30 days prior to the consummation of any such transaction. 

8.6    Except as expressly provided in the Plan or pursuant to action of the Administrator under the Plan, no Participant
shall have any rights by reason of any subdivision or consolidation of shares of stock of any class, the payment of any dividend, any increase or decrease in the number of shares of stock of any class or any dissolution, liquidation, merger, or
consolidation of the Company or any other corporation. Except as expressly provided in the Plan or pursuant to action of the Administrator under the Plan, no issuance by the Company of shares of stock of any class, or securities convertible into
shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number of shares of Common Stock subject to an Award or the grant or exercise price of any Award. The existence of the Plan, any Award
Agreements and the Awards granted hereunder shall not affect or restrict in any way the right or power of the Company to make or authorize (i) any adjustment, recapitalization, reorganization or other change in the Company’s capital
structure or its business, (ii) any merger, consolidation dissolution or liquidation of the Company or sale of Company assets or (iii) any sale or issuance of securities, including without limitation, securities with rights superior to
those of the Common Stock or which are convertible into or exchangeable for Common Stock. The Administrator may treat Participants and Awards (or portions thereof) differently under this Section 8. 

  
 8 

 9.    General Provisions Applicable to Awards. 

 9.1    Transferability. Except as the Administrator may otherwise determine or provide in an Award
Agreement or otherwise, in any case in accordance with Applicable Laws, Awards shall not be sold, assigned, transferred, pledged or otherwise encumbered by the person to whom they are granted, either voluntarily or by operation of law, except by
will or the laws of descent and distribution, and, during the life of the Participant, shall be exercisable only by the Participant. References to a Participant, to the extent relevant in the context, shall include references to authorized
transferees. 
 9.2    Documentation. Each Award shall be evidenced in an Award Agreement, which may be in
such form (written, electronic or otherwise) as the Administrator shall determine. Each Award may contain terms and conditions in addition to those set forth in the Plan. 

9.3    Discretion. Except as otherwise provided by the Plan, each Award may be made alone or in addition or
in relation to any other Award. The terms of each Award to a Participant need not be identical, and the Administrator need not treat Participants or Awards (or portions thereof) uniformly. 

9.4    Termination of Status. The Administrator shall determine the effect on an Award of the disability,
death, retirement, authorized leave of absence or any other change or purported change in a Participant’s Service Provider status and the extent to which, and the period during which, the Participant, the Participant’s legal
representative, conservator, guardian or Designated Beneficiary may exercise rights under the Award, if applicable. 

9.5    Withholding. Each Participant shall pay to the Company, or make provision satisfactory to the
Administrator for payment of, any taxes required by law to be withheld in connection with Awards to such Participant no later than the date of the event creating the tax liability. Except as the Administrator may otherwise determine, all such
payments shall be made in cash or by certified check. Notwithstanding the foregoing, to the extent permitted by the Administrator, Participants may satisfy such tax obligations in whole or in part by delivery of shares of Common Stock, including
shares retained from the Award creating the tax obligation, valued at their Fair Market Value. The Company may, to the extent permitted by Applicable Laws, deduct any such tax obligations from any payment of any kind otherwise due to a Participant.

 9.6    Amendment of Award. The Administrator may amend, modify or terminate any outstanding Award,
including but not limited to, substituting therefor another Award of the same or a different type, changing the date of exercise or settlement, and converting an Incentive Stock Option to a Non-Qualified Stock
Option. The Participant’s consent to such action shall be required unless (i) the Administrator determines that the action, taking into account any related action, would not materially and adversely affect the Participant, or (ii) the
change is permitted under Sections 8 and 10.6 hereof. 
 9.7    Conditions on Delivery of Stock. The
Company will not be obligated to deliver any shares of Common Stock pursuant to the Plan or to remove restrictions from shares 

  
 9 

 
previously delivered under the Plan until (i) all conditions of the Award have been met or removed to the satisfaction of the Company, (ii) in the opinion of the Company’s counsel,
all other legal matters in connection with the issuance and delivery of such shares have been satisfied, including any applicable securities laws and any applicable stock exchange or stock market rules and regulations, and (iii) the Participant
has executed and delivered to the Company such representations or agreements as the Administrator deems necessary or appropriate to satisfy the requirements of any Applicable Laws. The inability of the Company to obtain authority from any regulatory
body having jurisdiction, which authority is determined by the Administrator to be necessary to the lawful issuance and sale of any securities hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such
shares as to which such requisite authority shall not have been obtained. 
 9.8    Acceleration. The
Administrator may at any time provide that any Award shall become immediately vested and/or exercisable in full or in part, free of some or all restrictions or conditions, or otherwise realizable in full or in part, as the case may be. 

10.    Miscellaneous.  

10.1    No Right To Employment or Other Status. No person shall have any claim or right to be granted an
Award, and the grant of an Award shall not be construed as giving a Participant the right to continued employment or any other relationship with the Company. The Company expressly reserves the right at any time to dismiss or otherwise terminate its
relationship with a Participant free from any liability or claim under the Plan or any Award, except as expressly provided in an applicable Award Agreement. 

10.2    No Rights As Stockholder; Certificates. Subject to the provisions of the applicable Award Agreement,
no Participant or Designated Beneficiary shall have any rights as a stockholder with respect to any shares of Common Stock to be distributed with respect to an Award until becoming the record holder of such shares. Notwithstanding any other
provision of the Plan, unless otherwise determined by the Administrator or required by any Applicable Laws, the Company shall not be required to deliver to any Participant certificates evidencing shares of Common Stock issued in connection with any
Award and instead such shares of Common Stock may be recorded in the books of the Company (or, as applicable, its transfer agent or stock plan administrator). The Company may place legends on any stock certificates issued under the Plan deemed
necessary or appropriate by the Administrator in order to comply with Applicable Laws. 
 10.3    Effective Date and
Term of Plan. The Plan shall become effective on the date on which it is adopted by the Board. No Awards shall be granted under the Plan after the completion of ten years from the earlier of (i) the date on which the Plan was adopted
by the Board or (ii) the date the Plan was approved by the Company’s stockholders, but Awards previously granted may extend beyond that date in accordance with the terms of the Plan. 

10.4    Amendment of Plan. The Administrator may amend, suspend or terminate the Plan or any portion thereof
at any time; provided that no amendment of the Plan shall materially and adversely affect any Award outstanding at the time of such amendment without the consent of the affected Participant. Awards outstanding under the Plan at the time of any
suspension or termination of the Plan shall continue to be governed in accordance with the terms 

  
 10 

 
of the Plan and the applicable Award Agreement, as in effect prior to such suspension or termination. The Board shall obtain stockholder approval of any Plan amendment to the extent necessary to
comply with Applicable Laws. 
 10.5    Provisions for Foreign Participants. The Administrator may modify Awards
granted to Participants who are foreign nationals or employed outside the United States or establish subplans or procedures under the Plan to address differences in laws, rules, regulations or customs of such foreign jurisdictions with respect to
tax, securities, currency, employee benefit or other matters. 
 10.6    Section 409A. 

(a)    General. The Company intends that all Awards be structured in compliance with, or to satisfy an exemption
from, Section 409A, such that no adverse tax consequences, interest, or penalties under Section 409A apply in connection with any Awards. Notwithstanding anything herein or in any Award Agreement to the contrary, the Administrator may,
without a Participant’s prior consent, amend this Plan and/or Awards, adopt policies and procedures, or take any other actions (including amendments, policies, procedures and actions with retroactive effect) as are necessary or appropriate to
preserve the intended tax treatment of Awards under the Plan, including without limitation, any such actions intended to (A) exempt this Plan and/or any Award from the application of Section 409A, and/or (B) comply with the
requirements of Section 409A, including without limitation any such regulations, guidance, compliance programs and other interpretative authority that may be issued after the date of grant of any Award. The Company makes no representations or
warranties as to the tax treatment of any Award under Section 409A or otherwise. The Company shall have no obligation under this Section 10.6 or otherwise to take any action (whether or not described herein) to avoid the imposition of
taxes, penalties or interest under Section 409A with respect to any Award and shall have no liability to any Participant or any other person if any Award, compensation or other benefits under the Plan are determined to constitute non-compliant, “nonqualified deferred compensation” subject to the imposition of taxes, penalties and/or interest under Section 409A. 

(b)    Separation from Service. With respect to any Award that constitutes “nonqualified deferred
compensation” under Section 409A, any payment or settlement of such Award that is to be made upon a termination of a Participant’s Service Provider relationship shall, to the extent necessary to avoid the imposition of taxes under
Section 409A, be made only upon the Participant’s “separation from service” (within the meaning of Section 409A), whether such “separation from service” occurs upon or subsequent to the termination of the
Participant’s Service Provider relationship. For purposes of any such provision of this Plan or any Award Agreement relating to any such payments or benefits, references to a “termination,” “termination of employment” or
like terms shall mean “separation from service.” 
 (c)    Payments to Specified Employees.
Notwithstanding any contrary provision in the Plan or any Award Agreement, any payment(s) of “nonqualified deferred compensation” that are otherwise required to be made under an Award to a “specified employee” (as defined under
Section 409A and determined by the Administrator) as a result of his or her “separation from service” shall, to the extent necessary to avoid the imposition of taxes under Code Section 409A(a)(2)(B)(i), be delayed until the
expiration of the six-month period 

  
 11 

 
immediately following such “separation from service” (or, if earlier, until the date of death of the specified employee) and shall instead be paid (in a manner set forth in the Award
agreement) on the day that immediately follows the end of such six-month period or as soon as administratively practicable thereafter (without interest). Any payments of “nonqualified deferred
compensation” under such Award that are, by their terms, payable more than six months following the Participant’s “separation from service” shall be paid at the time or times such payments are otherwise scheduled to be made. 

10.7    Limitations on Liability. Notwithstanding any other provisions of the Plan, no individual acting as a
director, officer, other employee or agent of the Company will be liable to any Participant, former Participant, spouse, beneficiary, or any other person for any claim, loss, liability, or expense incurred in connection with the Plan or any Award,
nor will such individual be personally liable with respect to the Plan because of any contract or other instrument he or she executes in his or her capacity as an Administrator, director, officer, other employee or agent of the Company. The Company
will indemnify and hold harmless each director, officer, other employee and agent of the Company to whom any duty or power relating to the administration or interpretation of the Plan has been or will be granted or delegated, against any cost or
expense (including attorneys’ fees) or liability (including any sum paid in settlement of a claim with the Administrator’s approval) arising out of any act or omission to act concerning this Plan unless arising out of such person’s
own fraud or bad faith.
 10.8    Lock-Up Period. Participants shall not
offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common
Stock (or other securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) of the Company
held by Participant (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed 180 days following the effective date of any
registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to accommodate regulatory restrictions on (i) the publication or other distribution of research
reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in FINRA Rule 2241, or any successor provisions or amendments thereto). Participants shall execute and deliver such other
agreements as may be reasonably requested by the Company or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. The obligations described in this Section 10.8 shall not apply to a
registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely
to a Securities and Exchange Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of
Common Stock (or other securities) subject to the foregoing restriction until the end of such 180 day (or other) period. 

10.9    Limitations on Transfer. A Participant shall not sell, assign, transfer, pledge, hypothecate or otherwise
dispose of, by operation of law or otherwise (collectively “Transfer”) any interest in any shares of Common Stock held by Participant except in 

  
 12 

 
compliance with the provisions herein, in the Company’s Bylaws and applicable securities laws. Furthermore, the shares of Common Stock shall be subject to a right of first refusal in favor
of the Company or its assignees as set forth in the Company’s Bylaws. Notwithstanding the foregoing, Participant may, subject to compliance with the transfer restrictions set forth in the Company’s Bylaws, transfer shares of Common Stock
to or for the benefit of any spouse, children, parents, uncles, aunts, siblings, grandchildren and any other relatives approved by the Board of Directors (collectively, “Approved Relatives”) or to a trust established solely
for the benefit of the Participant and/or Approved Relatives, provided that such shares of Common Stock shall remain subject to the provisions of this Plan and any other applicable agreements, and such permitted transferee shall, as a condition to
such transfer, deliver to the Company a written instrument confirming that such transferee shall be bound by all of the terms and conditions of this Plan and any other applicable agreements. The Company shall not be required (a) to transfer on
its books any of the shares of Common Stock that have been sold or otherwise transferred in violation of any of the provisions of this Plan, any other applicable agreement or the provisions of the Company’s Bylaws or (b) to treat as owner
of such shares of Common Stock or to accord the right to vote or pay dividends to any purchaser or other transferee to whom any such shares of Common Stock shall have been so sold or transferred. 

10.10    Data Privacy. As a condition of receipt of any Award, each Participant explicitly and unambiguously
consents to the collection, use and transfer, in electronic or other form, of personal data as described in this paragraph by and among, as applicable, the Company and its subsidiaries and affiliates for the exclusive purpose of implementing,
administering and managing the Participant’s participation in the Plan. The Company and its subsidiaries and affiliates may hold certain personal information about a Participant, including but not limited to, the Participant’s name, home
address and telephone number, date of birth, social security or insurance number or other identification number, salary, nationality, job title(s), any shares of stock held in the Company or any of its subsidiaries and affiliates, details of all
Awards, in each case, for the purpose of implementing, managing and administering the Plan and Awards (the “Data”). The Company and its subsidiaries and affiliates may transfer the Data amongst themselves as necessary for the
purpose of implementation, administration and management of a Participant’s participation in the Plan, and the Company and its subsidiaries and affiliates may each further transfer the Data to any third parties assisting the Company in the
implementation, administration and management of the Plan. These recipients may be located in the Participant’s country, or elsewhere, and the Participant’s country may have different data privacy laws and protections than the
recipients’ country. Through acceptance of an Award, each Participant authorizes such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing
the Participant’s participation in the Plan, including any requisite transfer of such Data as may be required to a broker or other third party with whom the Company or the Participant may elect to deposit any shares of Common Stock. The Data
related to a Participant will be held only as long as is necessary to implement, administer, and manage the Participant’s participation in the Plan. A Participant may, at any time, view the Data held by the Company with respect to such
Participant, request additional information about the storage and processing of the Data with respect to such Participant, recommend any necessary corrections to the Data with respect to the Participant or refuse or withdraw the consents herein in
writing, in any case without cost, by contacting his or her local human resources representative. The Company may cancel Participant’s ability to participate in the Plan and, in the Administrator’s discretion, the

  
 13 

 
Participant may forfeit any outstanding Awards if the Participant refuses or withdraws his or her consents as described herein. For more information on the consequences of refusal to consent or
withdrawal of consent, Participants may contact their local human resources representative. 

10.11    Severability. In the event any portion of the Plan or any action taken pursuant thereto shall be held
illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provisions had not been included, and the illegal or invalid
action shall be null and void. 
 10.12    Governing Documents. In the event of any contradiction between the
Plan and any Award Agreement or any other written agreement between a Participant and the Company or any Subsidiary of the Company that has been approved by the Administrator, the terms of the Plan shall govern, unless it is expressly specified in
such Award Agreement or other written document that a specific provision of the Plan shall not apply. 

10.13    Submission to Jurisdiction; Waiver of Jury Trial. By accepting an Award, each Participant
irrevocably and unconditionally consents to submit to the exclusive jurisdiction of the courts of the state of California and of the United States of America, in each case located in the state of California, for any action arising out of or relating
to the Plan (and agrees not to commence any litigation relating thereto except in such courts), and further agrees that service of any process, summons, notice or document by U.S. registered mail to the address contained in the records of the
Company shall be effective service of process for any litigation brought against it in any such court. By accepting an Award, each Participant irrevocably and unconditionally waives any objection to the laying of venue of any litigation arising out
of Plan or Award hereunder in the courts of the state of California or the United States of America, in each case located in the state of California, and further irrevocably and unconditionally waives and agrees not to plead or claim in any such
court that any such litigation brought in any such court has been brought in an inconvenient forum. By accepting an Award, each Participant irrevocably and unconditionally waives, to the fullest extent permitted by applicable law, any and all rights
to trial by jury in connection with any litigation arising out of or relating to the Plan or any Award hereunder. 

10.14    Governing Law. The provisions of the Plan and all Awards made hereunder shall be governed by and
interpreted in accordance with the laws of the state of California, disregarding choice-of-law principles of the law of any state that would require the application of
the laws of a jurisdiction other than California. 
 10.15    Restrictions on Shares; Claw-back Provisions.
Shares of Common Stock acquired in respect of Awards shall be subject to such terms and conditions as the Administrator shall determine, including, without limitation, restrictions on the transferability of shares of Common Stock, the right of
the Company to repurchase shares of Common Stock, the right of the Company to require that shares of Common Stock be transferred in the event of certain transactions, tag-along rights, bring-along rights,
redemption and co-sale rights and voting requirements. Such terms and conditions may be additional to those contained in the Plan and may, as determined by the Administrator, be contained in the applicable
Award Agreement or in an exercise notice, stockholders’ agreement or in such other agreement as the Administrator shall 

  
 14 

 
determine, in each case in a form determined by the Administrator. The issuance of such shares of Common Stock shall be conditioned on the Participant’s consent to such terms and conditions
and the Participant’s entering into such agreement or agreements. All Awards (including any proceeds, gains or other economic benefit actually or constructively received by Participant upon any receipt or exercise of any Award or upon the
receipt or resale of any shares of Common Stock underlying the Award) shall be subject to the provisions of any claw-back policy implemented by the Company, including, without limitation, any claw-back policy adopted to comply with the requirements
of the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder, to the extent set forth in such claw-back policy and/or in the applicable Award Agreement. 

10.16    Titles and Headings. The titles and headings of the Sections in the Plan are for convenience of reference
only and, in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control. 

10.17    Conformity to Securities Laws. Participant acknowledges that the Plan is intended to conform to the extent
necessary with all provisions of the Securities Act and the Exchange Act and any and all regulations and rules promulgated by the Securities and Exchange Commission thereunder, and state securities laws and regulations. Notwithstanding anything
herein to the contrary, the Plan and all Awards granted hereunder shall be administered only in such a manner as to conform to such laws, rules and regulations. To the extent permitted by Applicable Laws, the Plan and all Award Agreements shall be
