 OFFICE LEASE 

This Lease, which includes the preceding Summary and the exhibits attached hereto and incorporated herein by this reference
(the Lease, the Summary and the exhibits to be known sometimes collectively hereafter as the “Lease”), dated as of the date set forth in Section 1 of the Summary, is made by and between WALTON TORREY OWNER B, L.L.C. , a
Delaware limited liability company (“Landlord”), and REGULUS THERAPEUTICS INC., a Delaware corporation “Tenant”). 

ARTICLE 1 
 PROJECT,
BUILDING AND PREMISES 
 1.1 Project, Building and Premises. 

1.1.1 Premises. Upon and subject to the terms, covenants and conditions hereinafter set forth in this Lease, Landlord
hereby leases to Tenant and Tenant hereby leases from Landlord the premises described in Section 6.1 of the Summary (the “Premises”), which Premises are located in the Building (as defined in Section 6.2 of the Summary)
and located within the Project (as defined below). Landlord shall not have the right to relocate Tenant or the Premises during the Term of this Lease. Landlord acknowledges and agrees that no other tenants of the Project have any rights to lease the
Premises. 
 1.1.2 Building and Project. The Building is part of a multi-building commercial project known as
“Torrey Ridge Science Center” and located in the City of San Diego. The term “Project” or “Real Property” as used in this Lease, shall mean, collectively: (i) the Building; (ii) the other
existing buildings located at 10628 and 10528 Science Center Drive within the site which, as of the date hereof, are not owned by Landlord (collectively, the “Other Existing Buildings”); (iii) any outside plaza areas, walkways,
driveways, courtyards, public and private streets, transportation facilitation areas and other improvements and facilities now or hereafter constructed surrounding and/or servicing the Building and/or the Other Existing Buildings, which are
designated from time to time by Landlord (and/or any other owners of Torrey Ridge Science Center) as common areas appurtenant to or servicing the Building, the Other Existing Buildings and any such other improvements; (iv) any additional
buildings, improvements, facilities and common areas which Landlord (any other owners of Torrey Ridge Science Center and/or any common area association formed by Landlord, Landlord’s predecessor-in-interest and/or Landlord’s assignee for
the Project) may add thereto from time to time within or as part of the Project; and (v) the land upon which any of the foregoing are situated. The site plan depicting the current configuration of the Project is attached hereto as Exhibit A-1. The Building, as well as each of the Other Existing Buildings contain a subterranean parking facility (“Parking Facility”). Notwithstanding the foregoing or anything
contained in this Lease to the contrary, (1) Landlord has no obligation to expand or otherwise make any improvements within the Project, including, without limitation, any of the outside plaza areas, walkways, driveways, courtyards, public and
private streets, transportation facilitation areas and other improvements and facilities which may be depicted on Exhibit A-1 attached hereto (as the same may be modified by Landlord (and/or
any other owners of Torrey Ridge Science Center) from time to time without notice to Tenant), other than Landlord’s obligations (if any) specifically set forth in the Tenant Work Letter attached hereto as Exhibit B, including the
additional parking spaces adjacent to the Building designated specifically for Tenant’s and visitors’ use (which may be constructed by Landlord as provided in Article 12 hereof) and (2) Landlord (and/or any other owners of Torrey
Ridge Science Center) shall have the right from time to time to include or exclude any improvements or facilities within the Project, at such party’s sole election, as more particularly set forth in Section 1.1.3 below. Subject to
(i) all of the terms and conditions of this Lease, including the Rules and Regulations attached hereto as Exhibit D, (ii) Force Majeure events (as defined in Section 24.17 below), (iii) Landlord’s
commercially reasonable security requirements, and (iv) the requirements of applicable laws, Tenant shall have access to the Premises twenty-four (24) hours per day, seven (7) days per week throughout the Lease Term. 

1.1.3 Tenant’s and Landlord’s Rights. Tenant shall have the right to the exclusive use of the common corridors
and hallways, stairwells, elevators (if any), restrooms and other public or common areas located within the Building, and the non-exclusive use of those areas located on the Project that are designated by Landlord (and/or any other owners of Torrey
Ridge Science Center) from time to time as common areas for the Building; provided, however, that (i) Tenant’s use thereof shall be subject to (A) the provisions of any covenants, conditions and restrictions regarding the use thereof
now or hereafter recorded against the Project, and (B) such reasonable, non-discriminatory rules and regulations as Landlord may make from time to time (which shall be provided in writing to Tenant), and (ii) Tenant may not go on the roof
of Building or the Other Existing Buildings without Landlord’s prior consent (which may be withheld in Landlord’s sole and absolute discretion) and without otherwise being accompanied by a representative of Landlord (provided, however,
Tenant shall, pursuant to Section 24.33 hereof, have the right to access the roof for purposes of installing and maintaining a satellite dish and/or antenna thereon). Landlord (and/or any other owners of Torrey Ridge Science Center) reserve the
right from time to time to use any of the common areas of the Project, and the roof, risers and conduits of the Building and the Other Existing Buildings for telecommunications and/or any other purposes, and to do any of the following: (1) make
any changes, additions, improvements, repairs and/or replacements in or to the Project or any portion or elements thereof, including, without limitation, (x) changes in the location, size, shape and number of driveways, entrances, loading and
unloading areas, ingress, egress, direction of traffic, landscaped areas, walkways, public and private streets, plazas, courtyards, transportation facilitation areas and common areas, and (y) expanding or decreasing the size of the Project and
any common areas and other elements thereof, including adding, deleting and/or excluding buildings (including any of the Other Existing Buildings) thereon and therefrom; (2) close temporarily any of the common areas while engaged in making
repairs, improvements or alterations to the Project; (3) retain and/or form a common area association or associations under covenants, conditions and restrictions to own, manage, operate, maintain,


  

					
	                 
	  		  	 TORREY RIDGE SCIENCE CENTER

Regulus Therapeutics










 
repair and/or replace all or any portion of the landscaping, driveways, walkways, public and private streets, plazas, courtyards, transportation facilitation areas and/or other common areas
located outside of the Building and the Other Existing Buildings and, subject to Article 4 below, include the common area assessments, fees and taxes charged by the association(s) and the cost of maintaining, managing, administering and
operating the association(s), in Operating Expenses or Tax Expenses; and (4) perform such other acts and make such other changes with respect to the Project as Landlord may, in the exercise of good faith business judgment, deem to be
appropriate. Tenant’s use of the common areas shall also include the right to use, in accordance with the terms of Exhibit D (and other commercially reasonable rules and regulations promulgated by Landlord); any common area
amenities which may be located from time to time in the Project, including a fitness center, café, bocce ball court, barbecue pits, ping pong, seating areas and a conference center. 

1.2 Condition of Premises. Except as expressly set forth in this Lease and in the Tenant Work Letter, Landlord shall not
be obligated to provide or pay for any improvement, remodeling or refurbishment work or services related to the improvement, remodeling or refurbishment of the Premises, and Tenant shall accept the Premises in its “As Is” condition on the
Lease Commencement Date; provided that Landlord shall deliver the Premises when the Premises are Ready For Occupancy in good operating condition and repair, with all Systems and Equipment in good working condition, with all necessary maintenance and
repair performed and free and clear of debris; provided, however, in the event that, as of the date of execution of this Lease, the Base, Shell and Core of the Building and including the Building Systems (as defined in Section 1 of
Exhibit B), in its condition existing as of such date without regard to any of the Tenant Improvements, alterations or other improvements existing in the Premises as of the date hereof and/or to be constructed or installed by or
on behalf of Tenant in the Premises or Tenant’s use of the Premises, and based solely on an unoccupied basis (A) does not comply with applicable laws, including without limitation local and state building code requirements and Title 24
requirements, seismic, fire and life safety codes, and the ADA, in effect as of the date hereof or (B) contains latent defects, then Landlord shall be responsible, at its sole cost and expense which shall not be included in Operating Expenses
(except as otherwise permitted in Section 4.2 hereof), for correcting any such non-compliance to the extent required by applicable laws, and/or correcting any such latent defects as soon as reasonably possible after receiving notice thereof
from Tenant; provided, however, that if Tenant fails to give Landlord written notice of any such latent defects described in clause (B) hereinabove within one hundred eighty (180) days after the Lease Commencement Date, then the correction
of any such latent defects shall, subject to Landlord’s repair obligations in Section 7.2 hereof (and to the extent such correction is a responsibility of Tenant pursuant to Section 7.1 hereof), be Tenant’s responsibility at
Tenant’s sole cost and expense; provided, however, that the foregoing “warranty” period shall not apply to any defects pertaining to the roof of the Building; provided further, however, that such one hundred eighty (180) days
period shall be deemed to be twenty-four (24) months with respect to the HVAC system serving the Building. For the avoidance of all doubt, any maintenance, repairs or replacements to the mechanical, electrical or plumbing systems comprising the
Base, Shell and Core serving the Premises (and not necessitated due to Tenant’s acts or omissions) in the six (6) months after the Lease Commencement Date shall, except for any maintenance, repairs and replacements of the roof of the
Building (which shall, in any event, be included as part of Operating Expenses), be deemed “latent defects” for purposes of this Section 1.2 and shall not be included in Operating Expenses. 

1.3 Rentable Square Feet. The parties hereby stipulate that the Premises contain the rentable square feet set forth in
Section 6.1 of the Summary, and such square footage amount is not subject to adjustment or remeasurement by Landlord or Tenant. Accordingly, there shall be no adjustment in the Base Rent or other amounts set forth in this Lease which are
determined based upon the rentable square feet of the Premises. Notwithstanding the foregoing, the rentable square feet of the Premises may be adjusted in connection with any damage and destruction or condemnation, as more particularly set forth in
Article 11 and 12, respectively. 
 ARTICLE 2 

LEASE TERM AND EARLY ENTRY 

2.1 Term. The terms and provisions of this Lease shall be effective as of the date of this Lease except for the
provisions of this Lease relating to the payment of Rent. The term of this Lease (the “Lease Term”) shall be as set forth in Section 7.1 of the Summary and shall commence on the date (the “Lease Commencement
Date”) set forth in Section 7.2 of the Summary (subject, however, to the terms of the Tenant Work Letter), and shall terminate on the date (the “Lease Expiration Date”) set forth in Section 7.3 of the Summary,
unless this Lease is sooner terminated or extended as hereinafter provided. For purposes of this Lease, the term “Lease Year” shall mean each consecutive twelve (12) month period during the Lease Term, provided that the last
Lease Year shall end on the Lease Expiration Date. If Landlord does not deliver possession of the Premises to Tenant Ready for Occupancy on or before the anticipated Lease Commencement Date (as set forth in Section 7.2(ii) of the Summary),
Landlord shall not be subject to any liability nor shall the validity of this Lease nor the obligations of Tenant hereunder be affected. If the Lease Commencement Date is a date which is other than the anticipated Lease Commencement Date set forth
in Section 7.2(ii) of the Summary, then, following the Lease Commencement Date, Landlord shall deliver to Tenant an amendment to lease in the form attached hereto as Exhibit C, attached hereto, setting forth, among other
things, the Lease Commencement Date and the Lease Expiration Date, and Tenant shall execute and return such amendment to Landlord within five (5) business days after Tenant’s receipt thereof. If Tenant fails to execute and return the
amendment within such 5-business day period, Tenant shall be deemed to have approved and confirmed the dates set forth therein, provided that such deemed approval shall not relieve Tenant of its obligation to execute and return the amendment (and
such failure shall constitute a default by Tenant hereunder). If Landlord does not deliver such amendment to Tenant, the Lease Commencement Date shall be deemed to be the anticipated Lease Commencement Date set forth in Section 7.2(ii) of the
Summary. 
 2.2 Early Entry. Tenant’s early entry rights are set forth in Section 6.1 of Exhibit B.

(“Base Rent”) as set forth in Section 8 of the Summary, payable in equal monthly installments as set forth in Section 8 of the Summary in advance on or before the first day of each and every month during the Lease Term,

and 60/100 Dollars ($248,841.60), which amount shall be comprised of the following: (i) the Base Rent payable by Tenant for the Premises for the first (1st) and second (2nd) months of the Lease Term (i.e., Two Hundred Four Thousand Four Hundred Five and 60/100 Dollars ($204,405.60)); and (ii) the Estimated Expenses (as defined below) payable by Tenant
for the Premises for the first (1st) full month of the Lease Term (i.e., Forty-Four Thousand Four Hundred Thirty-Six Dollars ($44,436.00)). If any rental payment date (including the
Lease Commencement Date) falls on a day of the month other than the first day of such month or if any rental payment is for a period which is shorter than one month, then the rental for any such fractional month shall be a proportionate amount of a
full calendar month’s rental based on the proportion that the number of days in such fractional month bears to the number of days in the calendar month during which such fractional month occurs. 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. Landlord and Tenant acknowledge and agree that the abated rent for the first twelve months of the Lease Term (based on the Base Rent being
calculated based on 29,624 rentable square feet versus the actual rentable square feet in the Premises of 59,248) equals One Hundred Two Thousand Two Hundred Two and 80/100 Dollars ($102,202.80) (the “Abated Rent”). 

ARTICLE 4

4.1 Additional Rent. In addition to paying the Base Rent specified in Article 3 above, Tenant shall pay as additional
rent the sum of the following: (i) Tenant’s Share (as such term is defined below) of the annual Operating Expenses allocated to the Building (pursuant to Section 4.3.4 below); plus (ii) Tenant’s Share of the annual Tax

affecting the Project; (iv) the cost of landscaping, relamping, supplies, tools, equipment and materials, and all fees, charges and other costs (including reasonable consulting fees, legal fees and accounting fees directly related to such work)
incurred in connection with the management, operation, repair and maintenance of the Project; (v) any equipment rental agreements or management agreements (including the cost of any management fee and the fair rental value of any office space
provided thereunder); (vi) wages, salaries and other compensation and benefits of all persons directly engaged in the operation, management, maintenance or security of the Project (or, if such persons are involved in the operation, management,
maintenance or security of other projects, the wages, salaries and other compensation and benefits of such persons will be based upon the percentage or such person’s actual time devoted to work on the Project), and employer’s Social
Security taxes, unemployment taxes or insurance, and any other taxes which may be levied on such wages, salaries, compensation and benefits; (vii) payments under any easement, license, operating agreement, declaration, restrictive covenant,

of costs by the Project (including but not limited to, the CC&Rs described in Article 5 hereof); (viii) the cost of janitorial service, trash removal (provided, however, Operating
Expenses shall not include the cost of janitorial services and trash removal services provided to the Premises or the premises of other tenants of the Building and/or the Project or the cost of replacing light bulbs, lamps, starters and ballasts for
lighting fixtures in the Premises and the premises of other tenants in the Building and/or the Project to the extent such services are directly provided and paid for by Tenant pursuant to Section 6.6 below), alarm and security service, if any,
window cleaning, replacement of wall and floor coverings, ceiling tiles and fixtures in lobbies, corridors, restrooms and other common or public areas or facilities, maintenance and replacement of curbs and walkways, repair to roofs and re-roofing;
(ix) amortization (including interest on the unamortized cost) of the cost of acquiring or the rental expense of personal property used in the maintenance, operation and repair of the Project; (x) the cost of any capital improvements or
other costs (I) which are intended as a labor-saving device or to effect other economies in the operation or maintenance of the Project, (II) made to the Project or any portion thereof after the Lease Commencement Date that are required under
any governmental law or regulation, or (III) which are Conservation Costs (as defined below) and/or which are reasonably determined by Landlord to be in the best interests of the Project; provided, however, that if any such cost described in (I),
(II) or (III) above, is a capital expenditure, such cost shall be amortized (including interest on the unamortized cost) as Landlord shall reasonably determine; and (xi) the costs and expenses of complying with, or participating in,
conservation, recycling, sustainability, energy efficiency, waste reduction or other programs or practices implemented or enacted from time to time at the Building and/or Project, excluding, however, any capital improvement costs associated with the
foregoing items in this clause (xi) (collectively, “Conservation Costs”), and excluding LEED (Leadership in Energy and Environmental Design) rating or compliance system or program, including that currently coordinated through
the U.S. Green Building Council or Energy Star rating and/or compliance system or program. If Landlord is not furnishing any particular work or service (the cost of which, if performed by Landlord, would be included in Operating Expenses) to a
tenant who has undertaken to perform such work or service in lieu of the performance thereof by Landlord, Operating Expenses shall be deemed to be increased by an amount equal to the additional Operating Expenses which would reasonably have been
incurred during such period by Landlord if it had at its own expense furnished such work or service to such tenant. If any of (x) the Building, (y) the Other Existing Buildings (but only during the period of time the same are included by
Landlord within the Project) and (z) any additional buildings are added to the Project pursuant to Section 1.1.3 above (but only during the period of time after such additional buildings have been fully constructed and ready for occupancy
and are included by Landlord within the Project) are less than ninety-five percent (95%) occupied during all or a portion of any Expense Year, Landlord shall make an appropriate adjustment to the variable components of Operating Expenses for
such year or applicable portion thereof, employing sound accounting and management principles, to determine the amount of Operating Expenses that would have been paid had the Building, such Other Existing Buildings and such additional buildings (if
any) been ninety-five percent (95%) occupied; and the amount so determined shall be deemed to have been the amount of Operating Expenses for such year, or applicable portion thereof. 

Notwithstanding the foregoing, Operating Expenses shall not, however, include: (A) costs of leasing commissions,
attorneys’ fees and other costs and expenses incurred in connection with negotiations or disputes with present or prospective tenants or other occupants of the Project; (B) costs (including permit, license and inspection costs) incurred in
renovating or otherwise improving, decorating or redecorating rentable space for other tenants or vacant rentable space; (C) costs incurred due to the violation by Landlord of the terms and conditions of any lease of space in the Project;
(D) costs of overhead or profit increment paid to Landlord or to subsidiaries or affiliates of Landlord for services in or in connection with the Project to the extent the same exceeds the costs of overhead and profit increment included in the
costs of such services which could be obtained from third parties on a competitive basis; (E) except as otherwise specifically provided in this Section 4.2.3, costs of interest on debt or amortization on any mortgages, loan or refinancing
of the Building or the Real Property, and recordation taxes and rent payable under any ground lease of the Project; (F) costs of a capital nature for the Real Property, except as specifically set forth in Sections 4.2.3(x) and (xi) above
and clause (I) hereinbelow; (G) costs of repairs and maintenance actually reimbursed by any other party; (H) attorneys’ fees and other costs incurred in attempting to collect rent or evict tenants for nonpayment of rent;
(I) depreciation, amortization and interest payments (except as provided herein and except on materials, tools, supplies and vendor-type equipment purchased by Landlord to enable Landlord to supply services Landlord might otherwise contract for
with a third party where such depreciation, amortization and interest payments would otherwise have been included in the charge for such third party’s services, all as determined in accordance with standard real estate accounting practices,
consistently applied, and when depreciation or amortization is permitted or required, the item shall be amortized over its reasonably anticipated useful life); (J) costs, including penalties, fines and associated legal expenses, incurred due to
the violation by Landlord or any other tenant of the Real Property of applicable laws, that would not have been incurred but for any such violations by Landlord or any tenant of the Real Property; (K) the wages and benefits of any employee who
does not devote substantially all of his or her employed time to the Real Property unless such wages and benefits are prorated to reflect time spent on operating and managing the Real Property vis-à-vis time spent on matters unrelated to
operating and managing the Real Property; provided that in no event shall Operating Expenses for purposes of this Lease include wages and/or benefits attributable to personnel above the level of Building or Project manager; (L) costs incurred
by Landlord for the repair of damage to the Real Property, to the extent that Landlord is reimbursed by insurance proceeds (or would have been reimbursed had Landlord maintained the insurance required to be carried by Landlord under this Lease);
(M) expenses in connection with services or other benefits which are not provided to Tenant or for which Tenant is charged for directly but which are provided to another tenant or occupant of the Real Property free of charge; (N) costs of
correcting defects in the original construction of the Real Property; (O) tax penalties incurred as a result of Landlord’s negligence, inability or unwillingness to make payments when due or to file any income tax or informational returns
when due; (P) any bad debt loss, rent loss, or reserves for bad debts or rent loss (but Operating Expenses may include reasonable reserves imposed upon the Real Property as part of the assessments under any covenants, conditions and
restrictions recorded against the Real Property); (Q) costs associated with the operation of the business of the partnership or entity which constitutes Landlord as the same are distinguished from the costs of operation of the Real Property,
including partnership accounting and legal matters; (R) costs incurred to comply with applicable laws with respect to the

cleanup, removal, investigation and/or remediation of any Hazardous Materials (as such term is defined in Article 5 below) in, on or under the Real Property and/or the Building to the extent such
Hazardous Materials are: (1) in existence as of the Lease Commencement Date and in violation of applicable laws in effect as of the Lease Commencement Date, and were of such a nature that a federal, state or municipal governmental or
quasi-governmental authority, if it had then had knowledge of the presence of such Hazardous Materials, in the state and under the conditions that the same existed in the Building or on the Real Property, would have then required removal,
remediation or other action with respect to such Hazardous Materials; or (2) introduced onto the Real Property and/or the Building after the Lease Commencement Date by Landlord or any of Landlord’s agents, employees, contractors or other
tenants in violation of applicable laws in effect at the date of introduction, and were of such a nature that a federal, state or municipal governmental or quasi-governmental authority, if it had then had knowledge of the presence of such Hazardous
Materials, in the state and under the conditions that the same existed in the Building or on the Real Property, would have then required removal, remediation or other action with respect to such Hazardous Materials; (S) any Tax Expenses or
Utilities Costs; (T) rentals for items (except when needed in connection with normal repairs and maintenance of permanent systems) which if purchased, rather than rented, would constitute a capital improvement specifically excluded above;
(U) costs (including, without limitation, fines, penalties, interest, and costs of repairs, replacements, alterations and/or improvements) incurred in bringing the Real Property into compliance with laws in effect as of the Lease Commencement
Date and as interpreted by applicable governmental authorities as of such date, including, without limitation, any costs to correct building code violations pertaining to the initial design or construction of the Building or any other improvements
to the Real Property, to the extent such violations exist as of the Lease Commencement Date under any applicable building codes in effect and as interpreted by applicable governmental authorities as of such date; (V) costs for which Landlord
has been compensated by a management fee, to the extent that the inclusion of such costs in Operating Expenses would result in a double charge to Tenant; (W) costs for the initial development of the Real Property; (X) costs of acquisition
of sculptures, painting and other objects of art (except for maintenance costs but not replacement costs with respect thereto); (Y) costs arising out of the operation, management, maintenance or repair of any retail premises in the Project or
any other retail areas operated by Landlord or its agents, contractors or vendors to the extent such costs are uniquely attributable (and separately identifiable) to such retail premises or areas (as opposed to general office use tenancies) or are
extraordinary, separately identifiable expenses arising in connection therewith; (Z) costs arising from Landlord’s charitable or political contributions; (AA) costs of any “tap fees” or any sewer or water connection fees for the
benefit of any particular tenant of the Real Property; (BB) any “above-standard” cleaning, including, but not limited to construction cleanup or special cleanings associated with parties/events and specific tenant requirements in excess of
services provided to Tenant, including related trash collection, removal, hauling and dumping; (CC) “in-house” legal and/or accounting fees; (DD) any “finders fees”, brokerage commissions, job placement costs or job advertisement
costs; (EE) any expenses incurred by Landlord for use of any portions of the Real Property to accommodate shows, promotions, kiosks, displays, filming, photography, private events or parties, ceremonies, and advertising beyond the normal expenses
otherwise attributable to providing services; (FF) any balloons, flowers or other gifts provided to any entity whatsoever, to include, but not limited to, Tenant, other tenants, employees, vendors, contractors, prospective tenants and agents, and
(GG) any expenses expressly prohibited pursuant to any provision of this Lease. 
 4.2.4 “Systems and
Equipment” shall mean any plant (including any central plant), machinery, transformers, duct work, cable, wires, and other equipment, facilities, and systems designed to supply heat, ventilation, air conditioning and humidity or any other
services or utilities, or comprising or serving as any component or portion of the electrical, gas, steam, plumbing, sprinkler, communications, alarm, lab, security, or fire/life safety systems or equipment, or any other mechanical, electrical,
electronic, computer or other systems or equipment which serve the Building and/or any other building in the Project in whole or in part. 

4.2.5 “Tax Expenses” shall mean all federal, state, county, or local governmental or municipal taxes, fees,
assessments, charges or other impositions, whether general, special, ordinary or extraordinary, (including, without limitation, real estate taxes, general and special assessments, transit assessments, fees and taxes, child care subsidies, fees
and/or assessments, job training subsidies, fees and/or assessments, open space fees and/or assessments, housing subsidies and/or housing fund fees or assessments, public art fees and/or assessments, leasehold taxes or taxes based upon the receipt
of rent, including gross receipts or sales taxes applicable to the receipt of rent, 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), which Landlord shall pay during any Expense Year because of or in connection with the ownership, leasing and operation of the Project or Landlord’s interest therein. For purposes of this Lease, Tax Expenses
shall be calculated as if (i) the tenant improvements in the Building, the Other Existing Buildings and any additional buildings added to the Project pursuant to Section 1.1.3 above (but only during the period of time that such Other
Existing Buildings and additional buildings are included by Landlord within the Project) were fully constructed, and (ii) the Project, the Building, such Other Existing Buildings and such additional buildings (if any) and all tenant
improvements therein were fully assessed for real estate tax purposes. 
 4.2.5.1 Tax Expenses shall include, without
limitation: 
 (i) Any tax on Landlord’s rent, right to rent or other income from the Project or as against
Landlord’s business of leasing any of the Project; 
 (ii) Any assessment, tax, fee, levy or charge in addition to, or
in substitution, partially or totally, of any assessment, tax, fee, levy or charge previously included within the definition of real property tax, it being acknowledged by Tenant and Landlord that Proposition 13 was adopted by the voters of the
State of California in the June 1978 election (“Proposition 13”) and that assessments, taxes, fees, levies and charges may be imposed by governmental agencies for such services as fire protection, street, sidewalk and road
maintenance, refuse removal and for other governmental services formerly provided without charge to property

owners or occupants. It is the intention of Tenant and Landlord that all such new and increased assessments, taxes, fees, levies, and charges and all similar assessments, taxes, fees, levies and
charges be included within the definition of Tax Expenses for purposes of this Lease; 
 (iii) Any assessment, tax, fee,
levy, or charge allocable to or measured by the area of the Premises or the rent payable hereunder, including, without limitation, any gross income tax upon or with respect to the possession, leasing, operating, management, maintenance, alteration,
repair, use or occupancy by Tenant of the Premises, or any portion thereof; 
 (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; and 

(v) Any reasonable expenses incurred by Landlord in attempting to protest, reduce or minimize Tax Expenses. 

4.2.5.2 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 net 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, and (iii) any items paid by Tenant under Section 4.4 below. 

4.2.6 “Tenant’s Share” shall mean the percentage set forth in Section 9 of the Summary.
Tenant’s Share was calculated by dividing the number of rentable square feet of the Premises by the total rentable square feet in the Building (as set forth in Section 9 of the Summary), and stating such amount as a percentage.
Tenant’s Share shall be subject to readjustment in connection with any damage, destruction or condemnation as set forth in Articles 11 and 12. 

4.2.7 “Utilities Costs” shall mean all actual charges for utilities for the Building and the Project
(including utilities for the Other Existing Buildings and additional buildings, if any, added to the Project during the period of time the same are included by Landlord within the Project) which Landlord shall pay during any Expense Year, including,
but not limited to, the costs of water, sewer, gas and electricity, and the costs of HVAC and other utilities, including any lab utilities and central plant utilities (but excluding those charges for which Tenant and tenants directly reimburse
Landlord or otherwise pay directly to the utility company (and excluding, in the case of Tenant, electricity, water and gas which Tenant shall pay directly to the utility company)) as well as related fees, assessments, measurement meters and devices
and surcharges. Utilities Costs shall be calculated assuming the Building (and, during the period of time when such buildings are included by Landlord within the Project, the Other Existing Buildings and any additional buildings, if any, added to
the Project) are at least ninety-five percent (95%) occupied. If, during all or any part of any Expense Year, Landlord shall not provide any utilities (the cost of which, if provided by Landlord, would be included in Utilities Costs) to a
tenant (including Tenant) who has undertaken to provide the same instead of Landlord, Utilities Costs shall be deemed to be increased by an amount equal to the additional Utilities Costs which would reasonably have been incurred during such period
by Landlord if Landlord had at its own expense provided such utilities to such tenant. Utilities Costs shall include any costs of utilities which are allocated to the Project under any declaration, restrictive covenant, or other instrument
pertaining to the sharing of costs by the Project or any portion thereof, including any covenants, conditions or restrictions now or hereafter recorded against or affecting the Project. 

4.3 Calculation and Payment of Additional Rent. 

4.3.1 Payment of Operating Expenses, Tax Expenses and Utilities Costs. For each Expense Year ending or commencing within
the Lease Term, Tenant shall pay to Landlord, as Additional Rent, the following, which payment shall be made in the manner set forth in Section 4.3.2 below: (i) Tenant’s Share of Operating Expenses allocated to the Building pursuant
to Section 4.3.4 below; plus (ii) Tenant’s Share of Tax Expenses allocated to the Building pursuant to Section 4.3.4 below; plus (iii) Tenant’s Share of Utilities Costs allocated to the Building pursuant to
Section 4.3.4 below. 
 4.3.2 Statement of Actual Operating Expenses, Tax Expenses and Utilities Costs and Payment by
Tenant. Landlord shall endeavor to give to Tenant on or before the first (1st) day of June following the end of each Expense Year, a statement (the “Statement”) which
shall state the Operating Expenses, Tax Expenses and Utilities Costs incurred or accrued for such preceding Expense Year that are allocated to the Building pursuant to Section 4.3.4 below, and which shall indicate therein Tenant’s Share
thereof. Within thirty (30) days after Tenant’s receipt of the Statement for each Expense Year ending during the Lease Term, Tenant shall pay to Landlord the full amount of the Tenant’s Share of Operating Expenses, Tax Expenses and
Utilities Costs for such Expense Year, less the amounts, if any, paid during such Expense Year as the Estimated Expenses as defined in and pursuant to Section 4.3.3 below. If any Statement reflects that Tenant has overpaid Tenant’s Share
of Operating Expenses and/or Tenant’s Share of Tax Expenses and/or Tenant’s Share of Utilities Costs for such Expense Year, then Landlord shall, at Landlord’s option, either (i) remit such overpayment to Tenant within thirty
(30) days after such applicable Statement is delivered to Tenant, or (ii) credit such overpayment toward the additional Rent next due and payable to Tenant under this Lease. The failure of Landlord to timely furnish the Statement for any
Expense Year shall not prejudice Landlord from enforcing its rights under this Article 4. Even though the Lease Term has expired and Tenant has vacated the Premises, if the Statement for the Expense Year in which this Lease terminates reflects that
Tenant has overpaid and/or underpaid Tenant’s Share of the Operating Expenses and/or Tenant’s Share of Tax Expenses and/or Tenant’s Share of Utilities Costs for such Expense Year, then within thirty (30) days after
Landlord’s delivery of such Statement to Tenant, Landlord shall refund to Tenant any such overpayment, or Tenant 

  

					
	                 
	  	-6-	  	 TORREY RIDGE SCIENCE CENTER

shall pay to Landlord any such underpayment, as the case may be. The provisions of this Section 4.3.2 shall survive the expiration or earlier termination of the Lease Term. 

4.3.3 Statement of Estimated Operating Expenses, Tax Expenses and Utilities Costs. Landlord shall endeavor to give
Tenant a yearly expense estimate statement (the “Estimate Statement”) within ninety (90) days following the end of an Expense Year (or as soon thereafter as reasonably possible), which shall set forth Landlord’s reasonable
estimate (the “Estimate”) of the total amount of Tenant’s Share of the Operating Expenses, Tax Expenses and Utilities Costs allocated to the Building pursuant to Section 4.3.4 below for the then-current Expense Year shall
be, and which shall indicate therein Tenant’s Share thereof (the “Estimated 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 Expenses under this Article 4. Following Landlord’s delivery of the Estimate Statement for the then-current Expense Year, Tenant shall pay, with its next installment of Base Rent due, a fraction of the Estimated
Expenses for the then-current Expense Year (reduced by any amounts paid pursuant to the last sentence of this Section 4.3.3). Such fraction shall have as its numerator the number of months which have elapsed in such current Expense Year to the
month of such payment, both months inclusive, and shall have twelve (12) as its denominator. Until a new Estimate Statement is furnished, Tenant shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth
(1/12) of the total Estimated Expenses set forth in the previous Estimate Statement delivered by Landlord to Tenant. 

4.3.4 Allocation of Operating Expenses, Tax Expenses and Utilities Costs to Building. The parties acknowledge that the
Building is part of a multi-building commercial project consisting of the Building, and the Other Existing Buildings and such other buildings as Landlord (and/or any other owners of Torrey Ridge Science Center) may elect to construct and include as
part of the Project from time to time (the Other Existing Buildings and any such other buildings are sometimes referred to herein, collectively, as the “Other Buildings”), and that certain of the costs and expenses incurred in
connection with the Project (i.e. the Operating Expenses, Tax Expenses and Utilities Costs) shall be shared among the Building and/or such Other Buildings, while certain other costs and expenses which are solely attributable to the
Building and such Other Buildings, as applicable, shall be allocated directly to the Building and the Other Buildings, respectively. Accordingly, as set forth in Sections 4.1 and 4.2 above, Operating Expenses, Tax Expenses and Utilities Costs
are determined annually for the Project as a whole, and a portion of the Operating Expenses, Tax Expenses and Utilities Costs, which portion shall be determined by Landlord on an equitable basis, shall be allocated to the Building (as opposed to the
tenants of the Other Buildings), and such portion so allocated shall be the amount of Operating Expenses, Tax Expenses and Utilities Costs payable with respect to the Building upon which Tenant’s Share shall be calculated. Such portion of the
Operating Expenses, Tax Expenses and Utilities Costs allocated to the Building shall include all Operating Expenses, Tax Expenses and Utilities Costs which are attributable solely to the Building, and an equitable portion of the Operating Expenses,
Tax Expenses and Utilities Costs attributable to the Project as a whole. As an example of such allocation with respect to Tax Expenses and Utilities Costs, it is anticipated that Landlord (and/or any other owners of Torrey Ridge Science Center) may
receive separate tax bills which separately assess the improvements component of Tax Expenses for each building in the Project and/or Landlord may receive separate utilities bills from the utilities companies identifying the Utilities Costs for
certain of the utilities costs directly incurred by each such building (as measured by separate meters installed for each such building), and such separately assessed Tax Expenses and separately metered Utilities Costs shall be calculated for and
allocated separately to each such applicable building. In addition, in the event Landlord (and/or any other owners of Torrey Ridge Science Center) elect to subdivide certain common area portions of the Project such as landscaping, public and private
streets, driveways, walkways, courtyards, plazas, transportation facilitation areas and/or accessways into a separate parcel or parcels of land (and/or separately convey all or any of such parcels to a common area association to own, operate and/or
maintain same), the Operating Expenses, Tax Expenses and Utilities Costs for such common area parcels of land may be aggregated and then reasonably allocated by Landlord to the Building and such Other Buildings on an equitable basis as Landlord
(and/or any applicable covenants, conditions and restrictions for any such common area association) shall provide from time to time. 

4.3.5 Initial Twelve (12) Month Cap on Operating Expenses, Tax Expenses and Utilities Costs and Cap on Controllable
Operating Expenses. Notwithstanding anything to the contrary contained in this Article 4, in no event shall Tenant’s Share of Operating Expenses, Tax Expenses and Utilities Costs (and excluding, as provided in Section 4.2.7 above,
the costs of electricity, gas and water which are payable by Tenant directly to the utility company) for the first twelve (12) months of the Lease Term exceed Seventy-Five Cents ($0.75) per square foot of the Premises per month (the
“Twelve Month Cap”); provided, however, that in the event of a sale of the Building and/or the Project, then the foregoing Twelve Month Cap shall immediately be null and void and of no further force or effect. In addition, and
notwithstanding anything to the contrary contained in this Article 4, Landlord acknowledges and agrees that the aggregate “Controllable Expenses” (as hereinafter defined) included in Operating Expenses in any Expense Year after the
first Expense Year shall not increase by more than five percent (5%) on an annual basis over the actual aggregate Controllable Expenses included in Operating Expenses for any preceding Expense Year, but with no such limit on the amount of
Controllable Expenses which may be included in the Operating Expenses incurred during the first Expense Year. For purposes of this Section 4.3.5, “Controllable Expenses” shall mean all Operating Expenses except: (i) any
and all assessments, including assessment districts and government-mandated charges with respect to the Building or Real Property, or any part thereof; (ii) insurance carried by Landlord with respect to the Real Property and/or the operation
thereof; (iii) janitorial and cleaning expenses; and (iv) costs of capital expenditures, including, without limitation, costs of capital improvements, capital alterations, capital repairs, reasonable wages, salaries and other compensation
and benefits paid to Landlord’s employees, agents or contractors engaged in the operation, management, maintenance or security of the Building or Real Property, to the extent such wages, salaries and other compensation are for union personnel.
The provisions of this Section 4.3.5 do not apply to the Tax Expenses nor Utilities Costs.

 4.4 Taxes and Other Charges for Which Tenant Is Directly Responsible.
Tenant shall reimburse Landlord upon demand for all taxes or assessments actually paid by Landlord (except to the extent included in Tax Expenses by Landlord), excluding state, local and federal personal or corporate income taxes measured by the net
income of Landlord from all sources and estate and inheritance taxes, whether or not now customary or within the contemplation of the parties hereto, when: 

4.4.1 said taxes are measured by or reasonably attributable to the cost or value of Tenant’s equipment, furniture,
fixtures and other personal property located in the Premises, or by the cost or value of any leasehold improvements made in or to the Premises by or for Tenant, to the extent the cost or value of such leasehold improvements exceeds the cost or value
of a building standard build-out as determined by Landlord regardless of whether title to such improvements shall be vested in Tenant or Landlord; 

4.4.2 said taxes are assessed upon or with respect to the possession, leasing, operation, management, maintenance, alteration,
repair, use or occupancy by Tenant of the Premises or any portion of the Project; or 
 4.4.3 said taxes are assessed upon
this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the Premises. 

4.5 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 three (3) business days of when due, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the amount due plus any attorneys’ fees incurred by Landlord by reason of Tenant’s
failure to pay Rent and/or other charges when due hereunder; provided, however, that Landlord will waive the imposition of the late charge for the first late payment of Rent in any one (1) calendar year. 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, at law and/or in equity 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 by the date that they are due shall thereafter bear interest until paid at a rate (the “Interest Rate”) equal to
the lesser of (i) the “Prime Rate” or “Reference Rate” announced from time to time by the Bank of America (or such reasonable comparable national banking institution as selected by Landlord in the event Bank of America
ceases to exist or publish a Prime Rate or Reference Rate), plus four percent (4%), or (ii) the highest rate permitted by applicable law. 

4.6 Audit Rights. Tenant shall have the right, at Tenant’s cost, after reasonable notice to Landlord, to have
Tenant’s authorized employees or agents inspect, at Landlord’s California office during normal business hours, Landlord’s books, records and supporting documents concerning the Operating Expenses, Tax Expenses and Utilities Costs set
forth in any Statement delivered by Landlord to Tenant for a particular Expense Year pursuant to Section 4.3.2 above; provided, however, Tenant shall have no right to conduct such inspection or object to or otherwise dispute the amount of the
Operating Expenses, Tax Expenses and Utilities Costs set forth in any such Statement, unless Tenant notifies Landlord of such inspection request, completes such inspection, and demands an audit as set forth below within nine (9) months
immediately following Landlord’s delivery of the particular Statement in question (the “Review Period”); provided, further, that notwithstanding any such timely inspection, objection, dispute, and/or audit, and as a condition
precedent to Tenant’s exercise of its right of inspection, objection, dispute, and/or audit as set forth in this Section 4.6, Tenant shall not be permitted to withhold payment of, and Tenant shall timely pay to Landlord, the full amounts
as required by the provisions of this Article 4 in accordance with such Statement. However, such payment may be made under protest pending the outcome of any audit. In connection with any such inspection by Tenant, Landlord and Tenant shall
reasonably cooperate with each other so that such inspection can be performed pursuant to a mutually acceptable schedule, in an expeditious manner and without undue interference with Landlord’s operation and management of the Project. If after
such inspection and/or request for documentation, Tenant disputes the amount of the Operating Expenses, Tax Expenses and Utilities Costs set forth in the Statement, Tenant shall have the right, but not the obligation, within the Review Period, to
cause an independent certified public accountant which is not paid on a contingency basis and which is mutually approved by Landlord and Tenant (the “Accountant”) to complete an audit of Landlord’s books and records to
determine the proper amount of the Operating Expenses, Tax Expenses and Utilities Costs incurred and amounts payable by Tenant for the Expense Year which is the subject of such Statement. Such audit by the Accountant shall be final and binding upon
Landlord and Tenant. If Landlord and Tenant cannot mutually agree as to the identity of the Accountant within thirty (30) days after Tenant notifies Landlord that Tenant desires an audit to be performed, then the Accountant shall be one of the
“Big 4” accounting firms selected by Landlord, which is not paid on a contingency basis. If such audit reveals that Landlord has over-charged Tenant, then within thirty (30) days after the results of such audit are made available to
Landlord, Landlord shall reimburse to Tenant the amount of such over-charge. If the audit reveals that the Tenant was under-charged, then within thirty (30) days after the results of such audit are made available to Tenant, Tenant shall
reimburse to Landlord the amount of such under-charge. Tenant agrees to pay the cost of such audit unless it is subsequently determined that Landlord’s original Statement which was the subject of such audit was in error to Tenant’s
disadvantage by five percent (5%) or more of the total Operating Expenses, Tax Expenses and Utilities Costs which was the subject of such audit. The payment by Tenant of any amounts pursuant to this Article 4 shall not preclude Tenant from
questioning the correctness of any Statement provided by Landlord at any time during the Review Period, but the failure of Tenant to object thereto, conduct and complete its inspection and have the Accountant conduct and complete the audit as
described above prior to the expiration of the Review Period shall be conclusively deemed Tenant’s approval of the Statement in question and the amount of Operating Expenses, Tax Expenses and Utilities Costs shown thereon. In connection with
any inspection and/or audit conducted by Tenant pursuant to this Section 4.6, Tenant agrees to keep, and to cause all of Tenant’s employees and consultants and the Accountant to keep, all of Landlord’s books and records and the audit,
and all information pertaining thereto and the results thereof, strictly confidential (except to the extent disclosure is required in accordance with applicable law), and in connection therewith, Tenant shall cause such

employees, consultants and the Accountant to execute such reasonable confidentiality agreements as Landlord may require prior to conducting any such inspections and/or audits. 

ARTICLE 5 
 USE OF
PREMISES; HAZARDOUS MATERIALS; ODORS AND EXHAUST 
 5.1 Use. Tenant shall use the Premises solely for
laboratory research, general office, manufacturing and other related uses permitted under the Project zoning, all to the extent consistent with the character of the Building as a first-class, multi-tenant biotechnology project, and Tenant shall not
use or permit the Premises to be used for any other purpose or purposes whatsoever. 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 contrary to the provisions of
Exhibit D, attached hereto, or in violation of the laws of the United States of America, the state in which the Project is located, or the ordinances, regulations or requirements of the local municipal or county governing body or
other lawful authorities having jurisdiction over the Project. Tenant shall comply with the Rules and Regulations and all recorded covenants, conditions, and restrictions, and the provisions of all ground or underlying leases, now or hereafter
affecting the Project, including but not limited to, (i) that certain Declaration of Covenants, Conditions and Restrictions recorded August 28, 1991, as Instrument No. 1991-0440869 in the San Diego County Official Records, and
(ii) that certain Declaration of Covenants, Conditions, and Restrictions for Torrey Pines Science Center [Unit 2] recorded on June 27, 1994, as Instrument No. 1994-0405385 in the San Diego County Official Records (collectively, the
existing “CC&Rs”), as the same may be amended, amended and restated, supplemented or otherwise modified from time to time; provided that any such amendments, restatements, supplements or modifications do not materially modify
Tenant’s rights or obligations hereunder. In the event of a conflict between the Rules and Regulations and the other terms and provisions of this Lease, then such other terms and provisions of this Lease shall control. 

5.2 Hazardous Materials. 

5.2.1 Definitions: As used in this Lease, the following terms have the following meanings: 

(a) “Environmental Law” means any past, present or future federal, state or local statutory or common law, or
any regulation, ordinance, code, plan, order, permit, grant, franchise, concession, restriction or agreement issued, entered, promulgated or approved thereunder, relating to (a) the environment, human health or safety, including, without
limitation, emissions, discharges, releases or threatened releases of Hazardous Materials (as defined below) into the environment (including, without limitation, air, surface water, groundwater or land), or (b) the manufacture, generation,
refining, processing, distribution, use, sale, treatment, receipt, storage, disposal, transport, arranging for transport, or handling of Hazardous Materials. 

(b) “Environmental Permits” mean collectively, any and all permits, consents, licenses, approvals and
registrations of any nature at any time required pursuant to, or in order to comply with, any Environmental Law or otherwise desired by Landlord including, but not limited to, any Spill Control Countermeasure Plan and any Hazardous Materials
Management Plan. 
 (c) “Hazardous Materials” shall mean and include any hazardous or toxic materials,
substances or wastes as now or hereafter designated or regulated under any Environmental Law, including, without limitation, asbestos, petroleum, petroleum hydrocarbons and petroleum based products, urea formaldehyde foam insulation, polychlorinated
biphenyls (“PCBs”), freon and other chlorofluorocarbons, “biohazardous waste,” “medical waste,” “infectious agent”, “mixed waste” or other waste under California Health and Safety Code §§
117600 et, seq. 
 (d) “Release” shall mean with respect to any Hazardous Materials, any release, deposit,
discharge, emission, leaking, pumping, leaching, spilling, seeping, migrating, injecting, pumping, pouring, emptying, escaping, dumping, disposing or other movement of Hazardous Materials. 

5.2.2 Tenant’s Obligations – Environmental Permits. Tenant will (i) obtain and maintain in full force and
effect all Environmental Permits that may be required from time to time under any Environmental Laws applicable to Tenant or required in connection with Tenant’s use of the Premises and Tenant’s improvements and Alterations to the Premises
and (ii) be and remain in compliance with all terms and conditions of all such Environmental Permits and with all other limitations, restrictions, conditions, standards, prohibitions, requirements, obligations, schedules and timetables
contained in all Environmental Laws applicable to Tenant or the Premises. On or before the date Tenant commences business operations in the Premises and thereafter from time to time upon Landlord’s written request, Tenant shall provide to
Landlord all Environmental Permits pertaining to the Premises and Tenant’s business operations therein. 
 5.2.3
Tenant’s Obligations – Hazardous Materials. Except as expressly permitted herein, Tenant agrees not to cause or permit any Hazardous Materials to be brought upon, stored, used, handled, generated, released or disposed of on, in,
under or about the Premises, or any other portion of the Property by Tenant, its agents, employees, subtenants, assignees, licensees, contractors or invitees (collectively, “Tenant’s Parties”), without the prior written consent
of Landlord, which consent Landlord may withhold in its sole and absolute discretion. Landlord acknowledges that it is not the intent of this Section 5.2 to prohibit Tenant from operating its business for the uses permitted hereunder. Tenant
may operate its business according to the custom of Tenant’s industry so long as the use or presence of Hazardous Materials is strictly and properly monitored in accordance with applicable Environmental Laws. As a material inducement to
Landlord to allow Tenant to use Hazardous Materials in connection with its business, Tenant agrees to deliver to Landlord prior to the Lease Commencement Date a list 

  

					
	                 
	  	-9-	  	 TORREY RIDGE SCIENCE CENTER

Regulus Therapeutics










 
identifying each type of Hazardous Material to be present at the Premises and setting forth any and all governmental approvals or permits required in connection with the presence of such
Hazardous Material at the Premises (the “Hazardous Materials List”). Tenant shall deliver to Landlord an updated Hazardous Materials List on or prior to each annual anniversary of the Lease Commencement Date and shall also deliver
an updated Hazardous Materials List before any new Hazardous Materials are brought to the Premises. Tenant shall deliver to Landlord true and correct copies of the following documents (hereinafter referred to as the “Documents”)
relating to the handling, storage, disposal and emission of Hazardous Materials prior to the Lease Commencement Date or, if unavailable at that time, concurrently with the receipt from or submission to any Governmental Authority: permits; approvals;
reports and correspondence; storage and management plans; notices of violations of applicable Environmental Laws; plans relating to the installation of any storage tanks to be installed in, on, under or about the Premises (provided that installation
of storage tanks shall only be permitted after Landlord has given Tenant its written consent to do so, which consent Landlord may withhold in its sole and absolute discretion); and all closure plans or any other documents required by any and all
governmental authorities for any storage tanks installed in, on, under or about the Premises for the closure of any such storage tanks. Tenant shall not be required, however, to provide Landlord with any portion of the Documents containing
information of a proprietary nature, which Documents, in and of themselves, do not contain a reference to any Hazardous Materials or activities related to Hazardous Materials. Upon the expiration or earlier termination of this Lease, Tenant agrees
to promptly remove from the Premises, the Building and the Project, at its sole cost and expense, any and all Hazardous Materials, including any equipment or systems containing Hazardous Materials which are installed, brought upon, stored, used,
generated or released upon, in, under or about the Premises, the Building and/or the Project or any portion thereof by Tenant or any of Tenant’s Parties during the Term of this Lease. 

5.2.4 Landlord’s Right to Conduct Environmental Assessment. At any time during the Lease Term, Landlord shall have
the right, at Tenant’s sole cost and expense, to conduct an environmental assessment of the Premises (as well as any other areas in, on or about the Project that Landlord reasonably believes may have been affected adversely by Tenant’s use
of the Premises (collectively, the “Affected Areas”) in order to confirm that the Premises and the Affected Areas do not contain any Hazardous Materials in violation of applicable Environmental Laws or under conditions constituting
or likely to constitute a Release of Hazardous Materials. Such environmental assessment shall be a so-called “Phase I” assessment or such other level of investigation which shall be the standard of diligence in the purchase or lease of
similar property at the time, together with, at Tenant’s sole cost and expense, any additional investigation and report which would customarily follow any discovery contained in such initial Phase I assessment (including, but not limited to,
any so-called “Phase II” report). Such right to conduct such environmental assessment shall not be exercised more than once per calendar year unless Tenant is in default under this Section 5.2 (beyond the expiration of all applicable
notice and cure periods). Notwithstanding anything above to the contrary, Landlord shall pay for the actual, documented and reasonable costs of such assessments unless it is determined, based on such assessment, that Tenant was not in compliance
with this Section 5.2. 
 5.2.5 Tenant’s Obligations to perform Corrective Action. If the data from any
environmental assessment authorized and undertaken by Landlord pursuant to Section 5.2.4 indicates there has been a Release, threatened Release or other conditions with respect to Hazardous Materials on, under or emanating from the Premises and
the Affected Areas that may require any investigation and/or active response action, including without limitation active or passive remediation and monitoring or any combination of these activities (“Corrective Action”), Tenant
shall immediately undertake Corrective Action with respect to contamination if, and to the extent, required by the governmental authority exercising jurisdiction over the matter. Any Corrective Action performed by Tenant will be performed with
Landlord’s prior written approval and in accordance with applicable Environmental Laws, at Tenant’s sole cost and expense and by an environmental consulting firm (reasonably acceptable to Landlord). Tenant may perform the Corrective Action
before or after the expiration or earlier termination of this Lease, to the extent permitted by governmental agencies with jurisdiction over the Premises, the Building and the Project (provided, however, that any Corrective Action performed after
the expiration or earlier termination of this Lease shall be subject to the access fee provisions set forth below). Tenant or its consultant may install, inspect, maintain, replace and operate remediation equipment and conduct the Corrective Action
as it considers necessary, subject to Landlord’s reasonable approval. Tenant and Landlord shall, in good faith, cooperate with each other with respect to any Corrective Action after the expiration or earlier termination of this Lease so as not
to interfere unreasonably with the conduct of Landlord’s or any third party’s business on the Premises, the Building and the Project. Landlord shall provide access until Tenant delivers evidence reasonably satisfactory to Landlord that
Tenant’s Corrective Action activities on the Premises and the Affected Areas satisfy applicable Environmental Laws. It shall be reasonable for Landlord to require Tenant to deliver a “no further action” letter or substantially similar
document from the applicable governmental agency. Landlord shall continue to provide access and Tenant shall continue to pay the access fee until such time as Landlord is able to use the Premises and the Affected Areas for such purposes as Landlord
reasonably desires. Landlord’s “reasonableness” as used in the immediately preceding sentence shall be based on (i) the zoning of the Premises as of the date in question, and (ii) the logical uses of the Premises as of the
date in question. If Landlord desires to situate a tenant in the Premises, the Building and the Project and remediation of the Premises and the Affected Areas is ongoing, Landlord shall be deemed to be unable to use the Premises, the Building and
the Project in the way Landlord reasonably desires and Tenant shall be obligated to continue paying the access fee until such time as Landlord is able to situate said tenant in the Premises, the Building and/or the Project. Tenant agrees, to the
extent applicable and reasonably practicable, to install, at Tenant’s sole cost and expense, screening around its remediation equipment so as to protect the aesthetic appeal of the Premises, the Building and the Project. Tenant also agrees to
use reasonable efforts to locate its remediation and/or monitoring equipment, if any (subject to the requirements of Tenant’s consultant and governmental agencies with jurisdiction over the Premises, the Building and the Project) in a location
which will allow Landlord, to the extent reasonably practicable, the ability to lease the Premises, the Building and the Project to a subsequent user. Any Hazardous Materials contamination on, in, under or about the Premises and the Affected Areas
at the expiration or earlier termination of this Lease which is not disclosed by Tenant prior to the effective date of this Lease shall be presumed to have arisen in connection with Tenant’s environmental activities under the Lease.
Notwithstanding anything above to the contrary, if any clean-up or monitoring procedure is required by any applicable governmental 

  

					
	                 
	  	-10-	  	 TORREY RIDGE SCIENCE CENTER

Regulus Therapeutics










 
authorities in, on, under or about the Premises and the Affected Areas during the Lease Term as a consequence of any Hazardous Materials contamination and the procedure for clean-up is not
completed (to the satisfaction of Landlord and/or the governmental authorities) prior to the expiration or earlier termination of this Lease then, at Landlord’s election, (i) this Lease shall be deemed renewed for a term commencing on the
expiration or earlier termination of this Lease and ending on the date the clean-up procedure is anticipated to be completed; or (ii) Tenant shall be deemed to have impermissibly held over (and Article 16 of this Lease shall apply with
full force and effect) and Landlord shall be entitled to all damages directly or indirectly incurred, including, without limitation, damages occasioned by the inability to relet the Premises and/or any other portion of the Building or a reduction of
the fair market or rental value of the Premises and/or the Building. 
 5.2.6 Tenant’s Duty to Notify Landlord
Regarding Releases. Tenant agrees to promptly notify Landlord of any Release of Hazardous Materials in the Premises, the Building or any other portion of the Project which Tenant becomes aware of during the Term of this Lease, whether caused by
Tenant or any other persons or entities. In the event of any release of Hazardous Materials caused or permitted by Tenant or any of Tenant’s Parties, Landlord shall have the right, but not the obligation, to cause Tenant, at Tenant’s sole
cost and expense, to immediately take all reasonable steps Landlord deems necessary or appropriate to remediate such Release and prevent any similar future release to the satisfaction of Landlord and Landlord’s mortgagee(s). 

5.2.7 Tenant’s Environmental Indemnity. To the fullest extent permitted by law, Tenant agrees to promptly
indemnify, protect, defend and hold harmless Landlord and Landlord’s members, partners, subpartners, independent contractors, officers, directors, shareholders, employees, agents, successors and assigns (collectively, “Landlord
Parties”) from and against any and all claims, damages, judgments, suits, causes of action, losses, liabilities, penalties, fines, expenses and costs (including, without limitation, clean-up, removal, remediation and restoration costs, sums
paid in settlement of claims, attorneys’ fees, consultant fees and expert fees and court costs) which arise or result from the presence of Hazardous Materials on, in, under or about the Premises, the Building or any other portion of the
Property and which are caused or permitted by Tenant or any of Tenant’s Parties during the Term of this Lease, including arising from or caused in whole or in part, directly or indirectly, by (i) the presence in, on, under or about the
Premises and the Affected Areas, of any Hazardous Materials; (ii) Tenant’s or other user’s actual, proposed or threatened use, treatment, storage, transportation, holding, existence, disposition, manufacturing, control, management,
abatement, removal, handling, transfer, generation or Release (past, present or threatened) of Hazardous Materials to, in, on, under, about or from the Premises and the Affected Areas; (iii) any past, present or threatened non-compliance or
violations of any Environmental Laws in connection with Tenant and/or the Premises and/or the Affected Areas, (iv) personal injury claims (v) the payment of any environmental liens, or the disposition, recording, or filing or threatened
disposition, recording or filing of any environmental lien encumbering or otherwise affecting the Premises and/or the Affected Areas, (vi) diminution in the value of the Premises and/or the Project, (vii) damages for the loss or
restriction of use of the Premises and/or the Project, including prospective rent, lost profits and business opportunities, (viii) sums paid in settlement of claims, (ix) reasonable attorneys’ fees, consulting fees and expert fees,
(x) the cost of any investigation of site conditions, and (xi) the cost of any repair, clean-up or remediation ordered by any governmental or quasi-governmental agency or body or otherwise deemed necessary in Landlord’s reasonable
judgment. Tenant’s obligations hereunder shall include, without limitation, and whether foreseeable or unforeseeable, all costs of any required or necessary repair, cleanup or detoxification or decontamination of the Premises, the Building
and/or the Project, or the preparation and implementation of any closure, remedial action or other required plans in connection therewith. For purposes of the indemnity provisions in this Section 5.2, any acts or omissions of Tenant and/or
Tenant’s Parties or others acting for or on behalf of Tenant (whether or not they are negligent, intentional, willful or unlawful) shall be strictly attributable to Tenant. The provisions of this Section 5.2.7 will survive the expiration
or earlier termination of this Lease. 
 5.2.8 Landlord and its successors and assigns shall indemnify, defend, reimburse and
hold Tenant, its employees and lenders, harmless from and against any and all damages, including the cost of remediation (but excluding loss of business, loss of profits or other consequential damages), which result from Hazardous Materials which
existed on the Premises prior to Tenant’s occupancy or which are caused by the negligence or willful misconduct of Landlord or Landlord Parties. Landlord’s obligations, as and when required by the Environmental Law, shall include, but not
be limited to, the cost of investigation, removal, remediation, restoration and/or abatement, and shall survive the expiration or termination of this Lease. Notwithstanding anything to the contrary in this Lease (including, without limitation the
provisions of this Paragraph 5.2.8, Tenant shall have no obligation to remediate, clean up, monitor, abate, or to comply with any law regarding, or to reimburse, release, indemnify, or defend Landlord or Landlord Parties with respect to any
Hazardous Materials which now or hereafter become regulated by any governmental authority or agency thereof and which Tenant or Tenant Parties did not store, dispose of, or transport in, use, or cause to be on the Premises in violation of any
Environmental Law. If any Hazardous Materials are present in the Premises (or the underlying soil or groundwater) and such presence was not caused by Tenant or any Tenant’s Parties, Landlord shall protect, indemnify, defend, and hold Tenant
harmless from and against any and all claims, liability, loss, proceedings, damages, causes of action, cost, or expense (including attorneys’ fees) arising therefrom (but excluding loss of business, loss of profits or other consequential
damages). 
 5.2.9 Landlord’s Termination Option for Certain Environmental Problems. If Hazardous Materials are
present at the Premises that are required by Environmental Law to be remediated and Tenant is not responsible therefor pursuant to Section 5.2, Landlord may, at its option, either (i) remediate such Hazardous Materials, in which event this
Lease shall continue in full force and effect or if the estimated cost to remediate such Hazardous Materials exceeds One Million Five Hundred Thousand Dollars ($1,500,000.00) (the “Threshold Amount”), give written notice to Tenant,
within thirty (30) days after receipt by Landlord of knowledge of the existence of such Hazardous Materials, of Landlord’s desire to terminate this Lease as of the date ninety (90) days following the date of such notice. In the event
Landlord elects to give such a termination notice, Tenant may, within ten (10) days thereafter, give written notice to Landlord of Tenant’s commitment to pay the amount by which the cost of the remediation of such Hazardous Materials
exceeds the Threshold Amount. Tenant shall provide Landlord 

  

					
	                 
	  	-11-	  	 TORREY RIDGE SCIENCE CENTER

Regulus Therapeutics










 
with such funds or satisfactory assurance thereof within thirty (30) days following such commitment. In such event, this Lease shall continue in full force and effect, and Landlord shall
proceed to make such remediation as soon as reasonably possible after the required funds are available. If Tenant does not give such notice and provide the required funds or assurance thereof within the time provided, this Lease shall terminate as
the date specified in Landlord’s termination notice. 
 5.2.10 Landlord’s Obligations Regarding Hazardous
Materials. Landlord confirms that it has received no written notice of the existence of any violation of Environmental Laws governing Hazardous Material existing at the Real Property as of the date of this Lease. To the extent it is determined
that Hazardous Material exists at the Real Property as of the Lease Commencement Date in violation of Environmental Laws, and such violation does not arise out of any acts or omissions of Tenant, its agents, employees or contractors, Landlord shall
promptly take such action as is necessary to comply with such Environmental Laws at no cost to Tenant. If, following the Lease Commencement Date, the Real Property becomes contaminated with Hazardous Material in violation of Environmental Laws
governing Hazardous Material, and such violation does not arise out of any acts or omissions of Tenant, its agents, employees or contractors, Landlord shall promptly take such commercial action as is necessary to comply with such Environmental Law.
Tenant acknowledges and agrees that Landlord has provided to Tenant a so-called “Phase I” environmental report relating to the Premises (the “Existing Phase I”) and an updated “Phase I” certified to Tenant (the
“Updated Phase I”). Landlord acknowledges and agrees that it has no other environmental reports relating to the Premises in its possession or control other than the Existing Phase I and the Updated Phase I delivered to Tenant prior
to the date of this Lease. 
 5.3 Odors and Exhaust. Tenant acknowledges that Landlord would not enter into this Lease
with Tenant unless Tenant assured Landlord that under no circumstances will the Premises be damaged by any exhaust from Tenant’s operations. Landlord and Tenant therefore agree as follows: 

5.3.1 Tenant shall not cause or permit (or conduct any activities that would cause) any release of any offensive or
objectionable odors or fumes of any kind from the Premises. 
 5.3.2 If the Building has a ventilation system that, in
Landlord’s judgment, is adequate, suitable, and appropriate to vent the Premises in a manner that does not release any offensive or objectionable odors affecting any indoor or outdoor part of the Premises, Tenant shall vent the Premises through
such system. If Landlord at any time determines that any existing ventilation system is inadequate, or if no ventilation system exists, Tenant shall in compliance with applicable laws vent all offensive or objectionable fumes and odors from the
Premises (and remove odors from Tenant’s exhaust stream) as Landlord requires. The placement and configuration of all ventilation exhaust pipes, louvers and other equipment shall be subject to Landlord’s approval. Tenant acknowledges
Landlord’s legitimate desire to maintain the Premises (indoor and outdoor areas) in an odor-free manner, and Landlord may require Tenant to abate and remove all offensive or objectionable odors in a manner that goes beyond the requirements of
Applicable Laws but only if such offensive or objectionable odors give rise to complaints from any other tenants of the Project and only if such odors would violate the sensibilities of a reasonable person. 

5.3.3 Tenant shall, at Tenant’s sole cost and expense, provide odor eliminators and other devices (such as filters, air
cleaners, scrubbers and whatever other equipment may in Landlord’s judgment be necessary or appropriate from time to time) to completely remove, eliminate and abate any offensive or objectionable odors, fumes or other substances in
Tenant’s exhaust stream that emanate from the Premises. Any work Tenant performs under this Section 5.3 shall constitute Alterations. 

5.3.4 Tenant’s responsibility to remove, eliminate and abate offensive or objectionable odors, fumes and exhaust shall
continue throughout the Term. 
 5.3.5 If Tenant fails to install satisfactory odor control equipment within ten
(10) business days after Landlord’s written request made at any time, then Landlord may, without limiting Landlord’s other rights and remedies, require Tenant to cease and suspend any operations in the Premises that cause offensive or
objectionable odors, fumes or exhaust. 
 ARTICLE 6 

SERVICES AND UTILITIES 

6.1 Standard Tenant Services. Landlord shall provide the following services on all days during the Lease Term, unless
otherwise stated below. 
 6.1.1 Landlord shall provide Building-standard heating and air conditioning capacity to the
Premises on a 24/7 basis. 
 6.1.2 Landlord shall provide Building-standard electrical wiring and facilities for use for
Building-standard lighting and standard equipment, as determined by Landlord. Landlord shall designate the electricity utility provider from time to time; provided, however, that should Tenant request that more than one electricity provider supply
electricity to the Building, Landlord shall not unreasonably withhold, condition or delay its approval in connection therewith; provided, however, that any costs associated with such additional electricity provider shall be borne by Tenant. 

6.1.3 Landlord shall provide facilities for city water from the regular Building outlets for drinking, lavatory and toilet
purposes (and Tenant shall pay the costs of the same directly to the utility provider). 

  

					
	                 
	  	-12-	  	 TORREY RIDGE SCIENCE CENTER

Regulus Therapeutics










 6.1.4 Landlord shall provide nonexclusive automatic passenger elevator service at
all times. 
 6.2 Overstandard Tenant Use. Tenant shall not overload the System and Equipment serving the Building
beyond the capacities of the same in such a manner as would result in damage thereto. 
 6.3 Separate Metering.
Tenant, at Tenant’s sole cost and expense, shall be separately metered for all of the electricity, water and natural gas and Tenant shall pay for the cost of all such utilities so separately metered directly to the provider. Upon
Landlord’s request, Tenant shall provide monthly electrical utility usage for the Premises to Landlord for the period of time requested by Landlord (in electronic or paper format) or, at Landlord’s option, provide any written authorization
or other documentation required for Landlord to request information regarding Tenant’s electricity usage with respect to the Premises directly from the applicable utility company. 

6.4 Interruption of Use. Subject to Section 6.7 below, Tenant agrees that Landlord shall not be liable for damages,
by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any service (including, but not limited to, any central plant or other lab system, telephone and telecommunication services), or for any diminution in the quality or
quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at
the Building or Project after reasonable effort to do so, by any accident or casualty whatsoever, by act or default of Tenant or other parties, or by any other cause beyond Landlord’s reasonable control; and such failures or delays or
diminution shall never be deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent or performing any of its obligations under this Lease. Furthermore, Landlord shall not
be liable under any circumstances for a loss of, or injury to, property (including scientific research and any intellectual property) or for injury to, or interference with, Tenant’s business, including, without limitation, loss of profits,
however occurring, through or in connection with or incidental to a failure to furnish any of the services or utilities as set forth in this Article 6. 

6.5 Additional Services. Landlord shall also have the exclusive right, but not the obligation, to provide any additional
services which may be required by Tenant, including, without limitation, locksmithing and additional repairs and maintenance, provided that Tenant shall pay to Landlord within ten (10) days after billing and as Additional Rent hereunder, the
sum of all costs to Landlord of such additional services plus a five percent (5%) administration fee. 
 6.6
Janitorial Service. Landlord shall not be obligated to provide any janitorial services to the Premises or replace any light bulbs, lamps, starters and ballasts for lighting fixtures within the Premises. Tenant shall be solely responsible, at
Tenant’s sole cost and expense, for (i) performing all janitorial services, trash removal and other cleaning of the Premises, and (ii) replacement of all light bulbs, lamps, starters and ballasts for lighting fixtures within the
Premises, all as appropriate to maintain the Premises in a first-class manner consistent with the first-class nature of the Building and Project. Such services to be provided by Tenant shall be performed by contractors and pursuant to service
contracts approved by Landlord, which approval shall not be unreasonably withheld, conditioned or delayed. Landlord shall have the right to inspect the Premises upon not less than 48 hours prior notice to Tenant and to require Tenant to provide
additional cleaning, if reasonably necessary. In the event Tenant shall fail to provide any of the services described in this Section 6.6 to be performed by Tenant within five (5) business days after written notice from Landlord, which
notice shall not be required in the event of an emergency, Landlord shall have the right to provide such services and any charge or cost incurred by Landlord in connection therewith shall be deemed Additional Rent due and payable by Tenant upon
receipt by Tenant of a written statement of cost from Landlord. 
 6.7 Abatement of Rent When Tenant is Prevented From
Using Premises. In the event that Tenant is prevented from using, and does not use, the Premises or any portion thereof, for five (5) consecutive business days (the “Eligibility Period”) as a result of (i) any repair,
maintenance or alteration performed by Landlord after the Lease Commencement Date and required to be performed by Landlord under this Lease or permitted pursuant to Section 24.30 below, or (ii) any failure by Landlord to provide to the
Premises any of the facilities for essential utilities and services required to be provided in Section 6.1.1 above, or (iii) any failure by Landlord to provide access to the Premises, then Tenant’s obligation to pay Base Rent and
Tenant’s Share of Operating Expenses, Tax Expenses and Utilities Costs shall be abated or reduced, as the case may be, from and after the first (1st) day following the Eligibility Period and continuing until such time that Tenant continues
to be so prevented from using, and does not use, the Premises or a portion thereof, in the proportion that the rentable square feet of the portion of the Premises that Tenant is prevented from using, and does not use, bears to the total rentable
square feet of the Premises; provided, however, that Tenant shall only be entitled to such abatement of rent if the matter described in clauses (i), (ii) or (iii) of this sentence is within Landlord’s reasonable control and caused by
Landlord’ gross negligence or willful misconduct. To the extent Tenant shall be entitled to abatement of rent because of a damage or destruction pursuant to Article 11 or a taking pursuant to Article 12, then the Eligibility Period shall not be
applicable. 
 6.8 Tenant’s Security System. Tenant shall be entitled to install, at Tenant’s sole cost and
expense, a separate security system for the Premises as an Alteration or as part of the Tenant Improvements; provided, however, that the plans and specifications for any such system shall be subject to Landlord’s reasonable approval, and any
such system must be compatible with the existing systems of the Project, Tenant’s obligation to indemnify, defend and hold Landlord harmless as provided in, and subject to, Article 10 below shall also apply to Tenant’s use and operation of
any such system, and the installation of such system shall otherwise be subject to the terms and conditions of this Article 6. At Landlord’s option, upon the expiration or earlier termination of this Lease, Tenant shall remove such security
system and repair any damage to the Premises resulting from such removal. Tenant shall at all times provide Landlord with a contact person who can disarm the security system and who is familiar with the

functions of the alarm system in the event of a malfunction, and Tenant shall provide Landlord with the alarm codes or other necessary information required to disarm the alarm system in the event
Landlord must enter the Premises. 
 ARTICLE 7 

REPAIRS 

7.1 Tenant’s Repairs. Subject to Landlord’s repair obligations in Sections 7.2 and 11.1 below, Tenant
shall, at Tenant’s own expense, keep the Premises, including all improvements, fixtures and furnishings therein, in good order, repair and condition at all times during the Lease Term, which repair obligations shall include, without limitation,
the obligation to promptly and adequately repair all damage to the Premises and replace or repair all damaged or broken fixtures and appurtenances, together with all portions of the HVAC, electrical, mechanical plumbing, life safety and lab systems
from the point that such systems solely serves the Premises and all portions of all fume hoods and other exhaust systems (all such systems collectively being referred to as the “Premises Systems”), in a first-class condition.
Tenant’s obligations shall include restorations, replacements or renewals, including capital expenditures for restorations, replacements or renewals which will have an expected life beyond the Term, when necessary to keep the Premises and all
improvements thereon or a part thereof and the Premises Systems in first-class order, condition and repair and in compliance with all applicable laws. Except as expressly set forth in this Lease, it is intended by the parties hereto that Landlord
shall have no obligation, in any manner whatsoever, to repair or maintain the Premises, the improvements located therein or the equipment therein, or the non-structural aspects of the Premises Systems, all of which obligations are intended to be the
expense of Tenant (whether or not such repairs, maintenance or restoration shall have an expected life extending beyond the Term). Tenant’s maintenance of the Premises Systems shall comply with the manufacturers’ recommended operating and
maintenance procedures. Tenant shall enter into and pay for maintenance contracts (in forms satisfactory to Landlord in its sole discretion) for the Premises Systems in accordance with the manufacturers’ recommended operating and maintenance
procedures. Such maintenance contracts shall be with reputable contractors, satisfactory to Landlord in its sole discretion, who shall have not less than ten (10) years of experience in maintaining such systems in biotechnical facilities.
Subject to Landlord’s repair obligations in this Lease, Tenant shall be solely responsible for the cost of all improvements or alterations to the Premises or the Premises Systems required by law. Notwithstanding the foregoing, at
Landlord’s option, or if Tenant fails to make such repairs, Landlord may, but need not, make such repairs and replacements, and Tenant shall pay Landlord the cost thereof, including a percentage of the cost thereof (to be uniformly established
for the Building) sufficient to reimburse Landlord for all overhead, general conditions, fees and other costs or expenses arising from Landlord’s involvement with such repairs and replacements forthwith upon being billed for same. 

7.2 Landlord’s Repairs. Anything contained in Section 7.1 above to the contrary notwithstanding, and subject
to Articles 11 and 12 below, Landlord shall repair and maintain the structural portions of the Building, including the roof, exterior walls, basic plumbing, HVAC and electrical systems serving the Building; provided, however, to the extent such
maintenance and repairs are caused by the act, neglect, fault of or omission of any duty by Tenant, its agents, servants, employees or invitees, Tenant shall pay to Landlord as Additional Rent, the reasonable cost of such maintenance and repairs.
Except as otherwise provided in this Lease, there shall be no abatement of rent and no liability of Landlord by reason of any injury to or interference with Tenant’s business arising from the making of any repairs, alterations or improvements
in or to any portion of the Project, Building or the Premises or in or to fixtures, appurtenances and equipment therein. Tenant hereby waives and releases its right to make repairs at Landlord’s expense under Sections 1941 and 1942 of the
California Civil Code; or under any similar law, statute, or ordinance now or hereafter in effect. Landlord shall use commercially reasonable efforts to cause any repairs to be made in a timely manner. 

ARTICLE 8 
 ADDITIONS
AND ALTERATIONS 
 8.1 Landlord’s Consent to Alterations. Tenant may not make any improvements,
alterations, additions or changes to the Premises (collectively, the “Alterations”) without first procuring the prior written consent of Landlord to such Alterations, which consent shall be requested by Tenant not less than fourteen
(14) days prior to the commencement thereof, and which consent shall not be unreasonably withheld, conditioned or delayed by Landlord; provided, however, Landlord may withhold its consent in its sole and absolute (but good faith) discretion
with respect to any Alterations which may affect the structural components of the Building or the Systems and Equipment or which can be seen from outside the Premises (the “Prohibited Alterations”). Notwithstanding the foregoing to
the contrary, Landlord’s prior consent shall not be required with respect to any interior Alterations to the Premises which (i) are not Prohibited Alterations, (ii) cost less than Fifty Thousand Dollars ($50,000.00) for any one
(1) job, and (iii) do not require a permit of any kind, as long as (A) Tenant delivers to Landlord notice and a copy of any final plans, specifications and working drawings for any such Alterations at least ten (10) days prior to
commencement of the work thereof, and (B) the other conditions of this Article 8 are satisfied including, without limitation, conforming to Landlord’s rules, regulations and insurance requirements which govern contractors. Tenant
shall pay for all overhead, general conditions, fees and other costs and expenses of the Alterations, and shall pay to Landlord a Landlord supervision fee of three percent (3%) of the hard cost of the Alterations. The construction of the
initial improvements to the Premises shall be governed by the terms of the Tenant Work Letter and not the terms of this Article 8. 

8.2 Manner of Construction. Landlord may impose, as a condition of its consent to all Alterations or repairs of the
Premises, such requirements as Landlord in its reasonable discretion may deem desirable, including, but not limited to, the requirement that Tenant utilize for such purposes only contractors, materials, mechanics and materialmen approved by
Landlord; provided, however, Landlord may impose such requirements as Landlord may 

  

					
	                 
	  	-14-	  	 TORREY RIDGE SCIENCE CENTER

Regulus Therapeutics










 
determine, in its reasonable discretion, with respect to any work affecting the structural components of the Building or Systems and Equipment (including designating specific contractors to
perform such work). In any event, all of Tenant’s contractors and subcontractors shall maintain the applicable insurance required in Exhibit E and Tenant shall ensure that Tenant’s contractors and subcontractors comply with the
requirements set forth therein. Tenant shall construct such Alterations and perform such repairs in compliance with any and all applicable rules and regulations of any federal, state, county or municipal code or ordinance and pursuant to a valid
building permit, issued by the city in which the Building is located, and in conformance with Landlord’s construction rules and regulations. Landlord’s approval of the plans, specifications and working drawings for Tenant’s
Alterations shall create no responsibility or liability on the part of Landlord for their completeness, design sufficiency, or compliance with all laws, rules and regulations of governmental agencies or authorities. All work with respect to any
Alterations must be done in a good and workmanlike manner and diligently prosecuted to completion to the end that the Premises shall at all times be a complete unit except during the period of work. Tenant shall cause all Alterations to be performed
in such manner as not to obstruct access by any person to the Building or Project or the common areas, and as not to obstruct the business of Landlord or other tenants of the Project, or interfere with the labor force working at the Project. If
Tenant makes any Alterations, Tenant agrees to carry “Builder’s All Risk” insurance in an amount approved by Landlord covering the construction of such Alterations, and such other insurance as Landlord may require, it being understood
and agreed that all of such Alterations shall be insured by Tenant pursuant to Article 10 below immediately upon completion thereof. Landlord may, in its discretion, require Tenant to obtain a lien and completion bond or some alternate form of
security satisfactory to Landlord in an amount sufficient to ensure the lien-free completion of such Alterations and naming Landlord as a co-obligee. Upon completion of any Alterations, Tenant shall (i) cause a Notice of Completion to be
recorded in the office of the Recorder of the county in which the Project is located in accordance with Section 3093 of the Civil Code of the State of California or any successor statute, (ii) deliver to the management office of the
Building a reproducible copy of the “as built” drawings of the Alterations, and (iii) deliver to Landlord evidence of payment, contractors’ affidavits and full and final waivers of all liens for labor, services or materials. 

8.3 Landlord’s Property. All Alterations, improvements and/or fixtures (excluding Tenant’s trade fixtures,
movable furniture and personal property) which may be installed or placed in or about the Premises shall be at the sole cost of Tenant and shall be and become the property of Landlord. Furthermore, Landlord may require that Tenant remove any
improvement (but not any Tenant Improvements) or Alteration upon the expiration or early termination of the Lease Term, and repair any damage to the Premises and Building caused by such removal so long as Landlord notified Tenant in writing at the
time Landlord approved such Alterations (or with respect to Alterations not requiring Landlord’s consent, at the time Tenant notified Landlord of such Alterations) that Landlord will require the removal of any such Alterations but only if
Tenant requested (in writing) that Landlord make such removal determination at the time Tenant requested Landlord’s consent to any such Alterations (or at the time Tenant provided Landlord with written notice of Alterations not requiring
Landlord’s consent). 
 8.4 Wi-Fi Network. Without limiting the generality of the foregoing, if Tenant desires to
install wireless intranet, Internet and communications network (“Wi-Fi Network”) in the Premises for the use by Tenant and its employees, then the same shall be subject to the provisions of this Section 8.4 (in addition to the
other provisions of this Article 8). In the event Landlord consents to Tenant’s installation of such Wi-Fi Network, Tenant shall, in accordance with Article 15 below, remove the Wi-Fi Network from the Premises prior to the termination of the
Lease. Tenant shall use the Wi-Fi Network so as not to cause any interference to other tenants in the Building or to other tenants at the Project or with any other tenant’s communication equipment, and not to damage the Building or Project or
interfere with the normal operation of the Building or Project, and Tenant hereby agrees to indemnify, defend and hold Landlord harmless from and against any and all claims, costs, damages, expenses and liabilities (including attorneys’ fees)
arising out of Tenant’s failure to comply with the provisions of this Section 8.4, except to the extent same is caused by the negligence or willful misconduct of Landlord and which is not covered by the insurance carried by Tenant under
this Lease (or which would not be covered by the insurance required to be carried by Tenant under this Lease). Should any interference occur, Tenant shall take all necessary steps as soon as reasonably possible and no later than three
(3) business days following such occurrence to correct such interference. If such interference continues after such three (3) business day period, Tenant shall immediately cease operating such Wi-Fi Network until such interference is
corrected or remedied to Landlord’s satisfaction. Tenant acknowledges that Landlord has granted and/or may grant telecommunication rights to other tenants and occupants of the Building and Project and to telecommunication service providers and
in no event shall Landlord be liable to Tenant for any interference of the same with such Wi-Fi Network. Landlord makes no representation that the Wi-Fi Network will be able to receive or transmit communication signals without interference or
disturbance. Tenant shall (i) be solely responsible for any damage caused as a result of the Wi-Fi Network, (ii) promptly pay any tax, license or permit fees charged pursuant to any laws or regulations in connection with the installation,
maintenance or use of the Wi-Fi Network and comply with all precautions and safeguards recommended by all governmental authorities, (iii) pay for all necessary repairs, replacements to or maintenance of the Wi-Fi Network, and (iv) be
responsible for any modifications, additions or repairs to the Building or Project, including without limitation, Building or Project systems or infrastructure, which are required by reason of the installation, operation or removal of Tenant’s
Wi-Fi Network. Should Landlord be required to retain professionals to research any interference issues that may arise and confirm Tenant’s compliance with the terms of this Section 8.4, Tenant shall reimburse Landlord for the costs
incurred by Landlord in connection with Landlord’s retention of such professionals, the research of such interference issues and confirmation of Tenant’s compliance with the terms of this Section 8.4 within twenty (20) days after
the date Landlord submits to Tenant an invoice for such costs. This reimbursement obligation is in addition to, and not in lieu of, any rights or remedies Landlord may have in the event of a breach or default by Tenant under this Lease.

 ARTICLE 9 

COVENANT AGAINST LIENS 

Tenant has no authority or power to cause or permit any lien or encumbrance of any kind whatsoever, whether created by act of
Tenant, operation of law or otherwise, to attach to or be placed upon the Project, Building or Premises, and any and all liens and encumbrances created by Tenant shall attach to Tenant’s interest only. Landlord shall have the right at all times
to post and keep posted on the Premises any notice which it deems necessary for protection from such liens. Tenant shall not cause or permit any lien of mechanics or materialmen or others to be placed against the Project, the Building or the
Premises with respect to work or services claimed to have been performed for or materials claimed to have been furnished to Tenant or the Premises, and, in case of any such lien attaching or notice of any lien, Tenant shall cause it to be
immediately released and removed of record. If any such lien is not released and removed within ten (10) business days after written notice of such lien is delivered by Landlord to Tenant, then Landlord may, at its option, take all action
necessary to release and remove such lien, without any duty to investigate the validity thereof, and all sums, costs and expenses, including reasonable attorneys’ fees and costs, incurred by Landlord in connection with such lien shall be deemed
Additional Rent under this Lease and shall immediately be due and payable by Tenant. 
 ARTICLE 10 

INDEMNIFICATION AND INSURANCE 

10.1 Indemnification and Waiver. Tenant hereby assumes all risk of damage to property and injury to persons, in, on, or
about the Premises from any cause whatsoever and agrees that Landlord and the Landlord Parties shall not be liable for, and are hereby released from any responsibility for, any damage to property or injury to persons or resulting from the loss of
use thereof, which damage or injury is sustained by Tenant or by other persons claiming through Tenant. Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any and all loss, cost, damage, expense and liability
(including without limitation court costs and reasonable attorneys’ fees) (collectively, the “Claims”) incurred in connection with or arising from any cause in, on or about the Premises (including, without limitation,
Tenant’s installation, placement and removal of Alterations, improvements, fixtures and/or equipment in, on or about the Premises), and any acts, omissions or negligence of Tenant or of any person claiming by, through or under Tenant, or of the
contractors, agents, servants, employees, licensees or invitees of Tenant or any such person, in, on or about the Premises, the Building and Project; provided, however, that Tenant’s indemnity shall, in no event, extend to loss of profits, loss
of business or other consequential damages incurred by Landlord or any Landlord Parties. Notwithstanding anything in this Section 10.1 to the contrary, the foregoing assumption of risk, release and indemnity shall not apply to any Claims to the
extent resulting from the gross negligence or willful misconduct of Landlord or any Landlord Parties and not insured (or required to be insured) by Tenant under this Lease (collectively, the “Excluded Claims”), and Landlord shall
indemnify, protect, defend and hold harmless Tenant and Tenant’s officers, agents and employees (collectively, “Tenant Parties”) from and against any such Excluded Claims, but only to the extent Landlord’s liability is not
waived and released by Tenant pursuant to the terms of Section 10.4 of this Lease (provided, however, that Landlord’s indemnity shall, in no event, extend to loss of profits, loss of business or other consequential damages incurred by
Tenant or any Tenant Parties). Each party’s agreement to indemnify the other pursuant to this Section 10.1 is not intended and shall not relieve any insurance carrier of its obligations under policies required to be carried by the
indemnifying party pursuant to the provisions of this Lease. The provisions of this Section 10.1 shall survive the expiration or sooner termination of this Lease. Notwithstanding anything in this Lease to the contrary, but subject to
Section 6.7 and Landlord’s indemnity obligations in this Lease, Landlord shall not be liable to Tenant for, and Tenant assumes all risk of, damage to personal property or scientific research or intellectual property, including loss of
records kept by Tenant within the Premises and damage or losses caused by fire, electrical malfunction, gas explosion or water damage of any type (including broken water lines, malfunctioning fire sprinkler systems, malfunctioning lab systems
including any malfunction of the central plant systems, roof leaks or stoppages of lines). Tenant further waives any claim for injury to Tenant’s business or loss of income relating to any such damage or destruction of personal property as
described above. 
 10.2 Tenant’s Compliance with Landlord’s Fire and Casualty Insurance. Tenant shall, at
Tenant’s expense, comply as to the Premises with all insurance company requirements pertaining to the use of the Premises. If Tenant’s conduct or use of the Premises causes any increase in the premium for such insurance policies, then
Tenant shall reimburse Landlord for any such increase. 
 10.3 Tenant’s Insurance. Tenant shall maintain the
following coverages in the following amounts. 
 10.3.1 Commercial general liability insurance written on the current

respect to Tenant’s CGL, business auto liability and employers liability insurance, with a limit of not less than $6,000,000 each occurrence. This insurance must (i) provide coverage at least as broad as the applicable primary coverages
(and, if excess, must be “true follow form”), (ii) include the Landlord Parties as additional insureds with respect to the CGL, (iii) apply on a primary basis with respect to any commercial general liability insurance carried by
the Landlord Parties, and (iv) provide that if the allocations of minimum primary and excess/umbrella limits established in this Section, Tenant may provide lower minimum limits of primary insurance so long as the minimum limit of the
excess/umbrella insurance is increased by the amount of the primary reduction. 
 10.3.4 Physical Damage Insurance –
Commercial property insurance covering (i) all furniture, trade fixtures, equipment, merchandise and all other items of Tenant’s property on the Premises installed by, for, or at the expense of Tenant, (ii) the Tenant
Improvements, including any Tenant Improvements which Landlord permits to be installed above the ceiling of the Premises or below the floor of the Premises, and (iii) all other improvements, alterations and additions to the Premises, including

endorsement, sprinkler leakage coverage and earthquake sprinkler leakage coverage. 
 10.3.5 Loss-of-income, business
interruption and extra-expense insurance in such amounts as will reimburse Tenant for direct and indirect loss of earnings attributable to prevention of loss of access to the Premises or to the Building as a result of such perils.

workers compensation insurance must fulfill applicable statutory requirements. The employers liability insurance must have limits of not less than $1,000,000 each accident for bodily injury by accident, $1,000,000 each employee for bodily injury by
disease, and $1,000,000 policy limit for bodily injury by disease. Policy shall also include a waiver of subrogation in favor of Landlord and Landlord Parties.

to cover liability insurance arising out of any auto (including owned, hired and non-owned autos), with a limit of not less than $1,000,000 each accident. 

10.3.8 Form of Policies. The minimum limits of policies of insurance required of Tenant under this Lease shall in no
event limit the liability of Tenant under this Lease. Such insurance shall: (i) name Landlord, and any other party it so specifies, as an additional insured; (ii) specifically cover the liability assumed by Tenant under this Lease,
including, but not limited to, Tenant’s obligations under Section 10.1 above; (iii) be issued by an insurance company having a rating of not less than A-VII in Best’s Insurance Guide or which is otherwise acceptable to Landlord
and licensed to do business in the state in which the Project is located; (iv) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and is non-contributing with any insurance requirement
of Tenant; (v) provide that said insurance shall not be canceled unless thirty (30) days’ prior written notice shall have been given to Tenant; (vi) contain a cross-liability endorsement or severability of interest clause
acceptable to Landlord; and (vii) with respect to the insurance required in Sections 10.3.1 and 10.3.3 above, have deductible amounts not exceeding Twenty Five Thousand Dollars ($25,000.00) unless Landlord approves the higher amount in
writing. Tenant shall deliver such policies or certificates thereof to Landlord on or before the Lease Commencement Date. If Tenant shall fail to procure such insurance, or to deliver such policies or certificate, within such time periods, Landlord
may, at its option, in addition to all of its other rights and remedies under this Lease, and without regard to any notice and cure periods set forth in Section 19.1, procure such policies for the account of Tenant, and the cost thereof shall
be paid to Landlord as Additional Rent within ten (10) days after delivery of bills therefor. Landlord may from time to time ask Tenant to seek or obtain other coverages or higher limits or broader coverage for required coverages, including
adjustments required by holders of indebtedness secured by the Project, and Tenant shall then use its best efforts promptly to obtain the coverages or limits. Tenant covenants to provide Landlord and any mortgagee or ground or underlying lessor of
Landlord notice in the event it receives notice of cancellation of its policies pursuant to subsection (v) above. 

10.4 Subrogation. Landlord and Tenant agree to have their respective insurance companies issuing property damage
insurance waive any rights of subrogation that such companies may have against Landlord or Tenant, as the case may be. Landlord and Tenant hereby waive any right that either may have against the other on account of any loss or damage to their
respective property to the extent such loss or damage is insurable under policies of insurance for fire and all risk coverage, theft, public liability, or other similar insurance. 

10.5 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.

 ARTICLE 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 of the Building or Project serving or providing access to the Premises shall be damaged by fire or other casualty, 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, shell, and core of the Premises and such common areas. Such restoration shall
be to substantially the same condition of the base, shell, and core of the Premises and 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 Project
and/or the Building, or the lessor of a ground or underlying lease with respect to the Building, or any other modifications to the common areas deemed desirable by Landlord, provided access to the Premises and any common restrooms serving the
Premises shall not be materially impaired. Upon the occurrence of any damage to the Premises, Tenant shall assign to Landlord (or to any party designated 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 damage to the tenant improvements and alterations installed in the Premises and shall return such tenant improvements and alterations to their original condition; provided that if
the costs of such repair of such tenant improvements and Alterations by Landlord exceeds the amount of insurance proceeds received by Landlord therefor from Tenant’s insurance carrier, as assigned by Tenant, the excess costs of such repairs
shall be paid by Tenant to Landlord prior to Landlord’s repair of the damage. In connection with such repairs and replacements of any such tenant improvements and Alterations, Tenant shall, prior to Landlord’s commencement of such
improvement work, 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. 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 if such damage is not the result of the negligence or willful misconduct of Tenant or Tenant’s employees, contractors, licensees, or invitees, Landlord shall allow Tenant a proportionate
abatement of Base Rent and Tenant’s Share of Operating Expenses, Tax Expenses and Utilities Costs to the extent Landlord is reimbursed from the proceeds of rental interruption insurance purchased by Landlord as part of Operating Expenses,
during the time and to the extent the Premises are unfit for occupancy for the purposes permitted under this Lease, and not occupied by Tenant as a result thereof. 

11.2 Landlord’s Option to Repair. Notwithstanding Section 11.1 above to the contrary, Landlord may elect not
to rebuild and/or restore the Premises, the Building and/or any other portion of the Project and instead terminate this Lease by notifying Tenant in writing of such termination within forty-five (45) days after the date Landlord becomes aware
of such damage, such notice to include a termination date giving Tenant ninety (90) days to vacate the Premises, but Landlord may so elect only if the Building 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) repairs cannot reasonably be substantially completed within one hundred twenty (120) days after the date of such damage (when such repairs are made without the payment
of overtime or other premiums); (ii) the holder of any mortgage on the Project and/or the Building or ground or underlying lessor with respect to the Project and/or the Building shall require that the insurance proceeds or any portion thereof
be used to retire the mortgage debt, or shall terminate the ground or underlying lease, as the case may be; or (iii) the damage is not fully covered, except for deductible amounts, by Landlord’s insurance policies. In addition, if the
Premises or the Building is destroyed or damaged to any substantial extent during the last year of the Lease Term, then notwithstanding anything contained in this Article 11, Landlord and/or Tenant shall have the option to terminate this Lease by
giving written notice to the other of the exercise of such option within thirty (30) days after such damage, in which event this Lease shall cease and terminate as of the date of such notice. Upon any such termination of this Lease pursuant to
this Section 11.2, Tenant shall pay the Base Rent and Additional Rent, properly apportioned up to such date of termination, and both parties hereto shall thereafter be discharged of all further obligations under this Lease, except for those
obligations which expressly survive the expiration or earlier termination of the Lease Term. 
 11.3 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 any other
portion of the Project, and any statute or regulation of the state in which the Project is located, including, 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 any other portion of the Project. 
 ARTICLE 12 

CONDEMNATION 

12.1 Permanent Taking. 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
upon ninety (90) days’ notice, provided such notice is given no later than one hundred eighty (180) days after the date of such taking, condemnation, deed or other instrument. If more

than twenty-five percent (25%) of the rentable square feet of the Premises is taken, or if access to the Premises is substantially impaired, Tenant shall have the option to terminate this
Lease upon ninety (90) days’ written notice, provided such notice is given no later than one hundred eighty (180) days after the date of such taking. Landlord shall be entitled to receive 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, and for moving expenses, so long as such claim does not diminish the award available to Landlord, or its ground lessor or mortgagee with respect to the Project, and such claim is payable separately to Tenant. All Rent
shall be apportioned as of the date of such termination, or the date of such taking, whichever shall first occur. If any part of the Premises shall be taken, and this Lease shall not be so terminated, the Base Rent and Tenant’s Share of
Operating Expenses, Tax Expenses and Utilities Costs 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. 

12.2 Temporary Taking. Notwithstanding anything to the contrary contained in this Article 12, 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 Tenant’s Share of Operating Expenses, Tax Expenses and Utilities
Costs 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. 
 ARTICLE 13 

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, and agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during the Lease Term, peaceably and quietly have, hold and enjoy the Premises
subject to the terms, covenants, conditions, 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. 

ARTICLE 14 

ASSIGNMENT AND SUBLETTING 

14.1 Transfers. Tenant shall not, without the prior written consent of Landlord (not to be unreasonably withheld,
conditioned or delayed), 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 such foregoing transfer of this Lease or any
interest hereunder by operation of law, sublet the Premises or any part thereof, or permit the use of the Premises by any persons other than Tenant and its employees (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 shall desire 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 twenty (20) days after the date of delivery of the Transfer
Notice, (ii) a description of the portion of the Premises to be transferred (the “Subject Space”), (iii) all of the terms of the proposed Transfer, the name and address of the proposed Transferee, and a copy of all
existing and/or proposed documentation pertaining to the proposed Transfer, (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, (v) a list of Hazardous Materials, certified by the
proposed Transferee to be true and correct, that the proposed Transferee intends to use or store in the Premises, and (vi) such other information as Landlord may reasonably require. 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 shall grant consent, within thirty (30) days after written
request by Landlord, Tenant shall pay to Landlord One Thousand Five Hundred Dollars ($1,500.00) to reimburse Landlord for its review and processing fees, and Tenant shall also reimburse Landlord for any reasonable legal fees incurred by Landlord in
connection with Tenant’s proposed Transfer, provided that Tenant shall not be responsible for any such legal costs in excess of One Thousand Five Hundred Dollars ($1,500.00). 

14.2 Landlord’s Consent. Landlord shall not unreasonably withhold, condition or delay its consent to any proposed
Transfer on the terms specified in the Transfer Notice. In no event shall Landlord be deemed to be unreasonable for declining to consent to a Transfer to a transferee jeopardizing directly or indirectly the status of Landlord or any of
Landlord’s affiliates as a Real Estate Investment Trust under the Internal Revenue Code of 1986 (as the same may be amended from time to time, the “Revenue Code”). Notwithstanding anything contained in this Lease to the
contrary, (w) no Transfer shall be consummated on any basis such that the rental or other amounts to be paid by the occupant, assignee, manager or other transferee thereunder would be based, in whole or in part, on the income or profits derived
by the business activities of such occupant, assignee, manager or other transferee; (x) Tenant shall not furnish or render any services to an occupant, assignee, manager or other transferee with respect to whom transfer consideration is
required to be paid, or manage or operate the Premises or any capital additions so transferred, with respect to which transfer consideration is being paid; (y) Tenant shall not consummate a Transfer with any person in which Landlord owns an
interest, directly or indirectly (by applying constructive ownership rules set forth in Section 856(d)(5) of the Revenue Code); and (z) Tenant shall not consummate a Transfer with any person or in any manner that could cause any portion of
the amounts received by Landlord pursuant to this Lease or any sublease, license or other arrangement for the right to use, occupy or possess any portion of the Premises to fail to qualify as “rents from real property” within the meaning
of Section 856(d) of the Revenue Code, or any similar or successor provision thereto or which could cause any other income of Landlord to fail to qualify as income

described in Section 856(c)(2) of the Revenue Code. 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, without limitation as to other reasonable grounds for withholding consent: 

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 Project; 
 14.2.2 The Transferee intends to use the Subject Space for purposes which are not permitted under
this Lease; 
 14.2.3 The Transferee is either a governmental agency or instrumentality thereof; 

14.2.4 The Transfer will result in more than a reasonable and safe number of occupants per floor within the Subject Space; 

14.2.5 The Transferee is not a party of reasonable financial worth and/or financial stability in light of the responsibilities
involved under the Lease on the date consent is requested; 
 14.2.6 The proposed Transfer would cause Landlord to be in
violation of another lease or agreement to which Landlord is a party, or would give an occupant of the Project a right to cancel its lease; 

14.2.7 The terms of the proposed Transfer will allow the Transferee to exercise a right of renewal, right of expansion, right
of first offer, or other similar right held by Tenant (or will allow the Transferee to occupy space leased by Tenant pursuant to any such right). 

14.2.8 Either the proposed Transferee, or any person or entity which directly or indirectly, controls, is controlled by, or is
under common control with, the proposed Transferee is actively, within ninety (90) days from the date of Tenant’s request for approval, negotiating with Landlord to lease space in the Project at such time and Landlord has space in the
Project available for lease for such proposed Transferee. 
 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 below), Tenant may 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 above, provided that if there are any changes in the terms and conditions from those specified in the Transfer Notice (i) such that Landlord would
initially have been entitled to refuse its consent to such Transfer under this Section 14.2, or (ii) which would cause the proposed Transfer to be more favorable to the Transferee than the terms set forth in Tenant’s original Transfer
Notice, 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). 

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 received by Tenant from such Transferee. “Transfer Premium” shall mean all rent, additional rent or other consideration payable by such
Transferee in excess of the Rent and Additional Rent payable by Tenant under this Lease on a per rentable square foot basis if less than all of the Premises is transferred, after deducting the reasonable expenses incurred by Tenant for (i) any
changes, alterations and improvements to the Premises in connection with the Transfer (but only to the extent approved by Landlord), (ii) any brokerage commissions and any reasonable marketing costs in connection with the Transfer,
(iii) rent abatement granted to the Transferee, and (iv) reasonable legal fees incurred in connection with such Transfer (collectively, the “Subleasing Costs”). Transfer Premium shall also include, but not be limited to,
key money and bonus money 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. 
 14.4 Landlord’s Option as to Subject
Space. Notwithstanding anything to the contrary contained in this Article 14, Landlord shall have the option, by giving written notice to Tenant within thirty (30) days after receipt of any Transfer Notice, to recapture the Subject Space.
Such recapture notice shall terminate this Lease with respect to the Subject Space as of the date stated in the Transfer Notice as the effective date of the proposed Transfer until the last day of the term of the Transfer as set forth in the
Transfer Notice. If this Lease is terminated with respect to less than the entire Premises, the Rent reserved herein shall be prorated on the basis of the rentable square feet retained by Tenant in proportion to the 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 the Subject Space under this Section 14.4, then, provided Landlord has consented to the proposed Transfer, Tenant shall be entitled to proceed to transfer the Subject Space to the proposed Transferee, subject to provisions of the
last paragraph of Section 14.2 above. 
 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; and (iv) 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 liability under this Lease. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books,
records and papers of 

  

					
	                 
	  	-20-	  	 TORREY RIDGE SCIENCE CENTER

Regulus Therapeutics










 
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 Landlord’s costs of such audit. 
 14.6 Additional Transfers.
Subject to Section 14.7 below, for purposes of this Lease, the term “Transfer” shall also include: (i) if Tenant is a partnership or limited liability company, the withdrawal or change, voluntary, involuntary or by operation of
law, of more than fifty percent (50%) of the partners or members, or transfer of more than fifty percent (50%) of the partnership or membership interests, within a twelve (12)-month period, or the dissolution of the partnership without
immediate reconstitution thereof; and (ii) if Tenant is a closely held corporation (i.e., whose stock is not publicly held and not traded through an exchange or over the counter), (A) the dissolution, merger, consolidation or other
reorganization of Tenant, (B) the sale or other transfer of more than an aggregate of fifty percent (50%) of the voting shares of Tenant (other than to immediate family members by reason of gift or death), within a twelve (12)-month
period, or (C) the sale, mortgage, hypothecation or pledge of more than an aggregate of fifty percent (50%) of the value of the unencumbered assets of Tenant within a twelve (12) month period. 

14.7 Affiliated Companies/Restructuring of Business Organization. The assignment or subletting by Tenant of all or any
portion of this Lease or the Premises to (i) a parent or subsidiary of Tenant, or (ii) any person or entity which controls, is controlled by or under common control with Tenant, or (iii) any entity which purchases all or substantially
all of the assets or stock of Tenant in one or a series of transactions, or (iv) any entity into which Tenant is merged or consolidated (all such persons or entities described in (i), (ii), (iii) and (iv) being sometimes
hereinafter referred to as “Affiliates”) shall not be deemed a Transfer under this Article 14 (and shall not allow Landlord to any Transfer Premium), provided that: 

14.7.1 Any such Affiliate was not formed as a subterfuge to avoid the obligations of this Article 14; 

14.7.2 Tenant gives Landlord prior written notice of any such assignment or sublease to an Affiliate; 

14.7.3 Any such Affiliate has, following the effective date of any such assignment or sublease, a tangible net worth, in the
aggregate, computed in accordance with generally accepted accounting principles, which is equal to or greater than Tenant as of the effective date of any such assignment or sublease and sufficient (in Landlord’s reasonable good faith opinion)
to meet the obligations of Tenant under this Lease; 
 14.7.4 Any such assignment or sublease, exclusive of such Transfer as
may occur pursuant to Section 14.6, shall be subject to all of the terms and provisions of this Lease, and such assignee or sublessee shall assume, in a written document reasonably satisfactory to Landlord and delivered to Landlord upon or
prior to the effective date of such assignment or sublease, all the obligations of Tenant under this Lease; and 
 14.7.5
Unless Tenant ceases to exist as an entity following such Affiliate transaction, Tenant shall remain fully liable for all obligations to be performed by Tenant under this Lease. 

An Affiliate that is an assignee of Original Tenant’s entire interest in this Lease may be referred to as an
“Affiliate Assignee.” 
 ARTICLE 15 

SURRENDER; OWNERSHIP AND REMOVAL OF PERSONAL PROPERTY 

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 a writing signed 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. 

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 and repairs which are specifically made the responsibility of Landlord hereunder excepted. Tenant’s restoration obligations may also include satisfying Landlord’s commercially reasonable procedures regarding the
cleaning of any lab systems and sealing any connection points of any such lab systems to the Premises, all at Tenant’s sole cost and expense. At least one hundred twenty (120) days prior to Tenant’s surrender of possession of any part
of the Premises, Tenant shall provide Landlord with a facility decommissioning and Hazardous Materials closure plan for the Premises prepared by an independent third party reasonably acceptable to Landlord (“Surrender Plan”). Within
ten (10) days prior to Tenant’s surrender of possession of any part of the Premises, Tenant shall provide Landlord with written evidence that Tenant has fulfilled Tenant’s obligations set forth in the Surrender Plan and that Tenant
has obtained all appropriate governmental releases pertaining to the Premises in accordance with applicable laws, including laws pertaining to the surrender of the Premises (“Exit Survey”). In addition, Tenant agrees to remain
responsible after 

  

					
	                 
	  	-21-	  	 TORREY RIDGE SCIENCE CENTER

Regulus Therapeutics










 
the surrender of the Premises for the remediation of any recognized environmental conditions set forth in the Surrender Plan and Exit Survey and compliance with any recommendations set forth in
the Exit Survey. Tenant shall, upon the expiration or earlier termination of this Lease, furnish to Landlord evidence that Tenant has closed all governmental permits and licenses, if any, issued in connection with Tenant’s or Tenant’s
Parties’ activities at the Premises. If any such governmental permits or licenses have been issued and Tenant fails to provide evidence of such closure on or before the expiration or earlier termination of this Lease, then until Tenant does so,
the holdover provisions of Article 16 of this Lease shall apply to the entire Premises. Upon such expiration or termination, Tenant shall, without expense to Landlord, satisfy any surrender obligations pursuant to Section 8.3 of this Lease and
shall, in any event, upon request of Landlord, remove or cause to be removed from the Premises all telephone, data, and other cabling and wiring (including any cabling and wiring associated with the Wi-Fi Network, if any) installed or caused to be
installed by Tenant (including any cabling and wiring, installed above the ceiling of the Premises or below the floor of the Premises), all debris and rubbish, and such items of furniture, equipment, free-standing cabinet work, 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. Tenant’s obligations under this Section 15.2 shall survive the expiration or earlier termination of this Lease. 

ARTICLE 16 
 HOLDING
OVER 
 If Tenant holds over after the expiration of the Lease Term hereof, with or without 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, and in such case Base Rent shall be payable at a monthly rate equal to one hundred fifty
percent (150%) of the Base Rent applicable during the last rental period of the Lease Term under this Lease. Such month-to-month tenancy shall be subject to every other term, covenant and agreement contained herein. Landlord hereby 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. Except with respect to Tenant’s occupancy of the Premises during the Temporary Extension Term, 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. Notwithstanding anything
set forth in this Article 16 to the contrary, Tenant shall have the one-time right to extend the initial Lease Term for a period of up to three (3) months thereafter (“Temporary Extension Term”) by delivering written notice of
the exercise of such right at least six (6) months prior to the expiration of the initial Lease Term, which notice shall specify the period of the Temporary Extension Term Tenant shall select (which period shall be not less than one
(1) month nor more than three (3) months), and provided that all of the following conditions are satisfied: (i) Tenant shall not have exercised its renewal right under the Extension Option Rider; (ii) at Landlord’s option,
in addition to all remedies available to Landlord under this Lease, at law or in equity, Tenant is not in default under this Lease (after expiration of any applicable notice and cure period) as of the date Tenant delivers such notice to Landlord or
the commencement of the Temporary Extension Term; and (iii) such renewal right is personal to the original Tenant executing this Lease (“Original Tenant”), and may only be exercised by the Original Tenant and an Affiliate
Assignee (and not by any other assignee, sublessee or other transferee of Original Tenant’s interest (or Affiliate Assignee’s interest) in this Lease). If Tenant timely exercises such renewal right, all of the terms and conditions of this
Lease shall apply during the Temporary Extension Term, provided, however, that the monthly Base Rent payable by Tenant during the Temporary Extension Term shall be equal to one hundred twenty-five percent (125%) of the monthly Base Rent
applicable during the last rental period of the Lease Term for such holdover (and one hundred fifty percent (150%) of monthly Base Rent applicable during the last rental period of the Lease Term thereafter). 

ARTICLE 17 
 ESTOPPEL
CERTIFICATES 
 Within ten (10) days following a request in writing by Landlord, Tenant shall execute and
deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be in a commercially reasonable form, 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 Landlord’s prospective mortgagees. Tenant shall execute and deliver whatever other instruments may be reasonably required for such purposes so long as such instruments are in a commercially
reasonable form. Failure of Tenant to timely execute and deliver such commercially reasonable estoppel certificate or other commercially reasonable 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. Failure by Tenant to so deliver such estoppel certificate shall be a material default of the provisions of this Lease. In addition, Tenant shall be liable to
Landlord, and shall indemnify Landlord from and against any loss, cost, damage or expense, incidental, consequential, or otherwise, including attorneys’ fees, arising or accruing directly or indirectly, from any failure of Tenant to execute or
deliver to Landlord any such estoppel certificate (except if such failure is caused by Tenant’s commercially reasonable objection to the form of such certificate or instrument). Upon request from time to time, Tenant agrees to provide to
Landlord, within twenty (20) days after Landlord’s delivery of written request therefor, current financial statements for Tenant, dated no earlier than one (1) year prior to such written request, certified as accurate by Tenant or, if
available, audited financial statements prepared by an independent certified public accountant with copies of the auditor’s statement;

provided, however, that the foregoing financial statement requirement shall not apply if and for so long as Tenant is in a publicly traded company and its financials are available on-line. 

ARTICLE 18 

SUBORDINATION 

This Lease is subject and subordinate to all present and future ground leases of the Project and to the lien of any mortgages
or trust deeds, now or hereafter in force against the Project, 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 or trust deeds, or the lessors under such ground lease, require in writing that this Lease be superior thereto. A condition precedent to the subordination of this Lease to any future ground or
underlying lease or to the lien of any future deed of trust is that Landlord shall obtain for the benefit of Tenant a commercially reasonable subordination, non-disturbance and attornment agreement from the lessor or lender of such future
instrument. Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of any such mortgage, or if any ground lease is terminated, to attorn, without any deductions or set-offs whatsoever, to the purchaser upon any such
foreclosure sale, or to the lessor of such ground lease, as the case may be, if so requested to do so by such purchaser or lessor, and to recognize such purchaser or lessor as the lessor under this Lease. Tenant shall, within ten (10) business
days of written request by Landlord, execute such further commercially reasonable 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, or ground 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. Within ten (10) business days following the date hereof, Landlord shall use commercially reasonable efforts to obtain from the current lender holding a lien on the Real
Property as of the date hereof, a subordination, non-disturbance and attornment agreement (“SNDA”) in favor of Tenant with respect to this Lease, in commercially reasonable form. 

ARTICLE 19 

TENANT’S DEFAULTS; LANDLORD’S REMEDIES 

19.1 Events of Default by Tenant. 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. 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 request therefor from Landlord; or 

19.1.2 Any failure by Tenant to observe or perform any other material 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 however, that any such notice shall be in lieu of, and not in addition to, any notice required
under California Code of Civil Procedure Section 1161 or any similar or successor law; and provided further 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 said default as soon as possible; or 

19.1.3 Abandonment or vacation of the Premises by Tenant. Abandonment is herein defined to include, but is not limited to, any
absence by Tenant from the Premises for five (5) business days or longer while in default of any provision of this Lease. 

19.2 Landlord’s Remedies Upon Default. Upon the occurrence of any such default by Tenant, Landlord shall have, in
addition to any other remedies available to Landlord at law or in equity, 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. 

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 any 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 

  

					
	                 
	  	-23-	  	 TORREY RIDGE SCIENCE CENTER

Regulus Therapeutics










 (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, 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 reasonably made to obtain a new tenant; plus 

(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
Interest Rate set forth in Section 4.5 above. 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 may, but shall not be obligated to, make any such payment or perform or otherwise cure any
such obligation, provision, covenant or condition on Tenant’s part to be observed or performed (and may enter the Premises for such purposes). In the event of Tenant’s failure to perform any of its obligations or covenants under this
Lease, and such failure to perform poses a material risk of injury or harm to persons or damage to or loss of property, then Landlord shall have the right to cure or otherwise perform such covenant or obligation at any time after such failure to
perform by Tenant, whether or not any such notice or cure period set forth in Section 19.1 above has expired. Any such actions undertaken by Landlord pursuant to the foregoing provisions of this Section 19.2.3 shall not be deemed a waiver
of Landlord’s rights and remedies as a result of Tenant’s failure to perform and shall not release Tenant from any of its obligations under this Lease. 

19.3 Payment by Tenant. Tenant shall pay to Landlord, within ten (10) days after delivery by Landlord to Tenant of
statements therefor: (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in connection with Landlord’s performance or cure of any of Tenant’s obligations pursuant to the provisions of
Section 19.2.3 above; and (ii) 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 legal fees and other amounts so expended. Tenant’s obligations under this Section 19.3 shall survive the expiration or sooner termination of the Lease Term. 

19.4 Sublessees 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. If Landlord elects 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. 

19.5 Waiver of Default. No waiver by Landlord of any violation or breach by Tenant of any of the terms, provisions and
covenants herein contained shall be deemed or construed to constitute a waiver of any other or later violation or breach by Tenant of the same or any other of the terms, provisions, and covenants herein contained. Forbearance by Landlord in
enforcement of one or more of the remedies herein provided upon a default by Tenant shall not be deemed or construed to constitute a waiver of such default. The acceptance of any Rent hereunder by Landlord following the occurrence of any default,
whether or not known to Landlord, shall not be deemed a waiver of any such default, except only a default in the payment of the Rent so accepted. 

19.6 Efforts to Relet. For the purposes of this Article 19, Tenant’s right to possession shall not be deemed to
have been terminated by efforts of Landlord to relet the Premises, by its acts of maintenance or preservation with respect to the Premises, or by appointment of a receiver to protect Landlord’s interests hereunder. The foregoing enumeration is
not exhaustive, but merely illustrative of acts which may be performed by Landlord without terminating Tenant’s right to possession. 

ARTICLE 20 
 SECURITY
DEPOSIT 
 Concurrent with Tenant’s execution of this Lease, Tenant shall deposit with Landlord a
security deposit (the “Security Deposit”) in the amount set forth in Section 10 of the Summary. The Security Deposit shall be held by Landlord as security for the faithful performance by Tenant of all the terms, covenants, and
conditions of this Lease to be kept and performed by Tenant during the Lease Term. If Tenant defaults with respect to any provisions of this Lease, including, but not limited to, the provisions relating to the payment of Rent, Landlord may, but
shall not be required to, use, apply or retain all or any part of the Security Deposit for the payment of any Rent or any other sum

in default, or for the payment of any amount that Landlord may spend or become obligated to spend by reason of Tenant’s default, or to compensate Landlord for any other loss or damage that
Landlord may suffer by reason of Tenant’s default. If any portion of the Security Deposit is so used or applied, Tenant shall, within ten (10) business days after written demand therefor, deposit cash with Landlord in an amount sufficient
to restore the Security Deposit to its original amount, and Tenant’s failure to do so shall be a default under this Lease. If Tenant shall fully and faithfully perform every provision of this Lease to be performed by it, the Security Deposit,
or any balance thereof, shall be returned to Tenant, or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder, within sixty (60) days following the expiration of the Lease Term. Tenant shall not be entitled to any
interest on the Security Deposit. Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code, and all other provisions of law, now or hereafter in force, which provide that 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 Tenant or to clean the Premises, it being agreed that Landlord may, in addition, claim those sums reasonably necessary to compensate Landlord for
any other loss or damage, foreseeable or unforeseeable, caused by the act or omission of Tenant or any officer, employee, agent or invitee of Tenant. 

ARTICLE 21 

COMPLIANCE WITH LAW 

Tenant shall not do anything or suffer anything to be done in or about the Premises 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 which affects the Premises and/or Tenant’s use of the Premises or Tenant’s Alterations or
improvements to the Premises including, without limiting the generality of the foregoing, those laws applicable to all lab and testing systems in the Premises. At its sole cost and expense, Tenant shall promptly comply with all such governmental
measures, other than the making of structural changes or changes to the Building’s life safety system (collectively the “Excluded Changes”); provided, however, to the extent such Excluded Changes are required due to or
triggered by Tenant’s improvements or alterations to and/or manner of use of the Premises, Landlord shall perform such work, at Tenant’s cost (which shall be paid by Tenant to Landlord within ten (10) days after Tenant’s receipt
of invoice therefor from Landlord). In addition, Tenant shall fully comply with all present or future programs intended to manage parking, transportation or traffic in and around the Project, 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. 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. 
 ARTICLE 22 

ENTRY BY LANDLORD 

Landlord reserves the right at all reasonable times and upon not less than 48 hours’ prior reasonable notice to Tenant
(except in cases of emergency) to enter the Premises to: (i) inspect them; (ii) show the Premises to prospective purchasers, mortgagees or to the ground lessors, or, within the last six (6) months of the Term, to prospective tenants
of the Premises; (iii) to post notices of nonresponsibility; or (iv) alter, improve or repair the Premises or the Building if necessary to comply with current building codes or other applicable laws, or for structural alterations, repairs
or improvements to the Building, or as Landlord may otherwise reasonably desire or deem necessary. Notwithstanding anything to the contrary contained in this Article 22, Landlord may enter the Premises at any time, without notice to Tenant, in
emergency situations and/or to perform janitorial or other services required of Landlord pursuant to this Lease. Any such entries shall be without the abatement of Rent and shall include the right to take such reasonable steps as required to
accomplish the stated purposes; provided, however, Landlord shall use reasonable efforts to minimize any disruptions to Tenant’s business operations in the Premises during any such entry. Subject to Section 6.7 of this Lease, Tenant hereby
waives any claims for damages or for any injuries or inconvenience to or interference with Tenant’s business, lost profits, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby. For each of the above
purposes, Landlord shall at all times have a key with which to unlock all the doors in the Premises, excluding Tenant’s vaults, safes and special security areas designated in advance by Tenant. In an emergency, Landlord shall have the right to
enter without notice and use any means that Landlord may deem proper to open the doors in and to the Premises. Any entry into the Premises 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. 
 ARTICLE 23 

PARKING 

Throughout the Lease Term, Tenant shall have the exclusive right to use, free of parking charges, the number of unreserved
parking spaces set forth in Section 12 of the Summary, which unreserved parking spaces are located in the subterranean Parking Facility servicing the Building and in the surface parking lot of the Project; provided, however, that
contingent on Landlord obtaining applicable permits, Landlord shall provide Tenant with up to ten (10) reserved parking spaces in the approximate location depicted on Exhibit F attached hereto for Tenant’s exclusive use.
Landlord shall use commercially reasonable efforts to obtain such applicable permits. Tenant’s continued right to use the parking spaces is conditioned upon (i) Tenant abiding by (A) the Parking Rules and Regulations which are in
effect on the date hereof, as set forth in the attached Exhibit D and all modifications and additions thereto which are prescribed from time to time for the orderly operation and use of the Parking Facility by


  

					
	                 
	  	-25-	  	 TORREY RIDGE SCIENCE CENTER

Regulus Therapeutics










 
Landlord, and/or Landlord’s Parking Operator (as defined below), and (B) all recorded covenants, conditions and restrictions affecting the Building, and (ii) upon Tenant’s
cooperation in seeing that Tenant’s employees and visitors also comply with the Parking Rules and Regulations (and all such modifications and additions thereto, as the case may be), any such other rules and regulations and covenants, conditions
and restrictions. Landlord (and/or any other owners of Torrey Ridge Science Center) specifically reserve the right to change the size, configuration, design, layout, location and all other aspects of the Parking Facility (including without
limitation, implementing paid visitor parking), and Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of Rent under this Lease, from time to time, close-off or restrict access to
the Parking Facility as long as such restriction is not imposed in a manner that is discriminatory to Tenant and is imposed in a similar manner on other tenants of the Project. Landlord may delegate its responsibilities hereunder to a parking
operator (the “Parking Operator”) in which case the Parking Operator shall have all the rights of control attributed hereby to Landlord. Any parking tax or other charges imposed by governmental authorities in connection with the use
of such parking shall be paid directly by Tenant or the parking users, or, if directly imposed against Landlord, Tenant shall reimburse Landlord for all such taxes and/or charges within ten (10) days after Landlord’s demand therefor. The
parking rights provided to Tenant pursuant to this Article 23 are provided solely for use by Tenant’s own personnel and such rights may not be transferred, assigned, subleased or otherwise alienated by Tenant without Landlord’s prior
approval, except in connection with an assignment of this Lease or sublease of the Premises made in accordance with Article 14 above. All visitor parking by Tenant’s visitors shall be subject to availability, as reasonably determined by
Landlord (and/or the Parking Operator, as the case may be), parking in such visitor parking areas as may be designated by Landlord (and/or the Parking Operator from time to time, and payment by such visitors of the prevailing visitor parking rate
(if any) charged by Landlord (and/or the Parking Operator) from time to time. Notwithstanding anything to the contrary in the foregoing, in no event shall Tenant be liable for any fees, whether such fees are directly billed to Tenant or are passed
on to Tenant via an increase in Operating Expenses, in connection with Landlord’s delegation of responsibilities to the Parking Operator. 

ARTICLE 24 

MISCELLANEOUS PROVISIONS 

24.1 Terms; Captions. 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. 
 24.2 Binding Effect. Each of the
provisions of this Lease shall extend to and shall, as the case may require, bind or inure to the benefit not only of Landlord and of Tenant, but also of their respective successors or assigns, provided this clause shall not permit any assignment by
Tenant contrary to the provisions of Article 14 above. 
 24.3 No Waiver. No waiver of any provision of this Lease
shall be implied by any failure of a party to enforce any remedy on account of the violation of such provision, even if such violation shall continue or be repeated subsequently, any waiver by a party of any provision of this Lease may only be in
writing, and no express waiver shall affect any provision other than the one specified in such waiver and that one only for the time and in the manner specifically stated. 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. 
 24.4 Modification of Lease. If any current or prospective mortgagee or ground
lessor for the Project requires modifications to this Lease, which modifications 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 commercially reasonable documents are required therefor and deliver the same to Landlord within ten (10) days following the request therefor. If
Landlord or any such current or prospective mortgagee or ground lessor require execution of a short form of Lease (provided that such form is in a commercially reasonable form) for recording, containing, among other customary provisions, the names
of the parties, a description of the Premises and the Lease Term, Tenant shall execute such short form of Lease and to deliver the same to Landlord within ten (10) days following the request therefor. 

24.5 Transfer of Landlord’s Interest. Landlord has the right to transfer all or any portion of its interest in the
Project, the Building and/or in this Lease, and upon any such transfer, Landlord shall automatically be released from all liability under this Lease and Tenant shall look solely to such transferee for the performance of Landlord’s obligations
hereunder after the date of transfer. The liability of any transferee of Landlord shall be limited to the interest of such transferee in the Project and such transferee shall be without personal liability under this Lease, and Tenant hereby
expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or under Tenant. Landlord may also assign its interest in this Lease to a mortgage lender as additional security but such assignment shall
not release Landlord from its obligations hereunder and Tenant shall continue to look to Landlord for the performance of its obligations hereunder. 

24.6 Prohibition Against Recording. Except as provided in Section 24.4 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, and the recording thereof in violation of this provision shall make this Lease null and void at Landlord’s election. 

24.7 Landlord’s Title; Air Rights. 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. 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. 
 24.8 Tenant’s Signs. 

24.8.1 Interior Signs. Tenant shall be entitled, at its sole cost and expense, to install identification signs in the
ground floor lobby of the Building. Such signs shall be installed by a signage contractor designated by Landlord. The location, quality, design, style, lighting and size of such signs shall be consistent with the Landlord’s Building standard
signage program and shall be subject to Landlord’s prior written approval, in its reasonable discretion. Upon the expiration or earlier termination of this Lease, Tenant shall be responsible, at its sole cost and expense, for the removal of
such signage and the repair of all damage to the Building caused by such removal. Except for such identification signs and except for Tenant’s Exterior Signs described below, Tenant may not install any signs on the exterior or roof of the
Building, the Other Existing Buildings or the common areas of the Building or the Project. 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 are subject to the prior approval of Landlord, in its commercially reasonable discretion. 

24.8.2 Exterior Signs. Subject to the approval of all applicable governmental and quasi- governmental entities, and
subject to all applicable governmental and quasi-governmental laws, rules, regulations and codes and any covenants, conditions and restrictions affecting the Real Property, Landlord hereby grants Tenant (i) the exclusive right to have two
(2) Building exterior identification signs in a location on the face of the Building approved by Landlord (“Façade Sign”), (ii) the exclusive right to have one (1) sign on the monument sign exclusively serving
the Building and (iii) the non-exclusive right to have one (1) sign on the monument sign serving the Project located on Science Center Drive, in each case containing the name of the Tenant in a form to be subsequently provided by Tenant
and reasonably approved by Landlord (collectively, the “Exterior Signs.”) The design, size, specifications, graphics, materials, manner of affixing, exact location, colors and lighting (if applicable) of Tenant’s Exterior Signs
shall be (i) consistent with the quality and appearance of the Project, (ii) subject to the approval of all applicable governmental and quasi-governmental authorities, and subject to all applicable governmental and quasi-governmental laws,
rules, regulations and codes and any covenants, conditions and restrictions affecting the Real Property, and (iii) subject to Landlord’s approval (which shall not be unreasonably withheld, conditioned or delayed). Tenant shall install
Tenant’s Exterior Signs at Tenant’s sole cost and expense. In addition, Tenant shall be responsible for all other costs attributable to the fabrication, insurance, lighting (if applicable), maintenance, repair and removal of Tenant’s
Exterior Signs. The signage rights granted to Tenant under this Section 24.8.2 are personal to the Original Tenant, any Affiliate Assignee and any Transferee that is a Landlord approved assignee of this Lease and may not be exercised or used by
or assigned to any other person or entity other than Original Tenant, any Affiliate Assignee or any such approved assignee. In addition, Original Tenant, any Affiliate Assignee or such approved assignee shall no longer have any right to
Tenant’s Exterior Signs if at any time during the Term the Original Tenant or such approved assignee or such Affiliate Assignee does not lease and occupy at least seventy-five percent (75%) of the entire Premises then leased by Original
Tenant hereunder or such approved assignee or Affiliate Assignee. Upon the expiration or sooner termination of this Lease, or upon the earlier termination of Tenant’s signage rights under this Section 24.8.2, Landlord shall have the right
to permanently remove Tenant’s Exterior Signs from the Building and/or the Project and to repair all damage to the Building and/or the Project resulting from such removal and restore the affected area to its original condition existing prior to
the installation of such Exterior Signs, and Tenant shall reimburse Landlord for the costs thereof. 
 24.9 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,
it being expressly understood and agreed that neither the method of computation of Rent nor any act of the parties hereto shall be deemed to create any relationship between Landlord and Tenant other than the relationship of landlord and tenant. 

24.10 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. 

24.11 Time of Essence. Time is of the essence of this Lease and each of its provisions. 

24.12 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. 

24.13 No Warranty. In executing and delivering this Lease, Tenant has not relied on any representation, including, but
not limited to, any representation whatsoever 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.

 24.14 Landlord Exculpation. Notwithstanding anything in this Lease to the
contrary, and notwithstanding any applicable law to the contrary, the liability of Landlord and the Landlord Parties under this Lease (including any successor landlord) and any recourse by Tenant against Landlord or the Landlord Parties shall be
limited solely and exclusively to an amount which is equal to the ownership interest of Landlord in the Project (excluding any proceeds thereof), and neither Landlord, nor any of the Landlord Parties 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. 

24.15 Entire Agreement. There are no oral agreements between the parties hereto affecting this Lease and this Lease
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. This Lease and any side letter or separate agreement executed by Landlord and Tenant in connection with this Lease and dated of even date herewith contain all of the terms, covenants, conditions,
warranties and agreements of the parties relating in any manner to the rental, use and occupancy of the Premises, shall be considered to be the only agreement between the parties hereto and their representatives and agents, and 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. All negotiations and oral agreements acceptable to both parties have been merged into and are included herein.
There are no other representations or warranties between the parties, and all reliance with respect to representations is based totally upon the representations and agreements contained in this Lease. 

24.16 Right to Lease. Landlord reserves the absolute right to effect such other tenancies in the Building, the Other
Existing Buildings and/or in any other building and/or any other portion of the Project as Landlord in the exercise of its sole business judgment shall determine to best promote the interests of the 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, the Other Existing Buildings or Project. 

24.17 Force Majeure. Any prevention, delay or stoppage due to strikes, lockouts, labor disputes, acts of God, 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 pursuant to this Lease and except with respect to Tenant’s obligations under the Tenant Work Letter (collectively, the “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. 

24.18 Waiver of Redemption by Tenant. Tenant hereby waives for Tenant and for all those claiming under Tenant all right
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. 

24.19 Notices. All notices, demands, statements or communications (collectively, “Notices”) given or
required to be given by either party to the other hereunder shall be in writing, shall be sent by overnight courier or delivered personally (i) to Tenant at the appropriate address set forth in Section 5 of the Summary, or to such other
place as Tenant may from time to time designate in a Notice to Landlord; or (ii) to Landlord at the addresses set forth in Section 3 of the Summary, or to such other firm or to such other place as Landlord may from time to time designate
in a Notice to Tenant. Any Notice will be deemed given on the date it is mailed as provided in this Section 24.19 or upon the date personal delivery is made or rejected. If Tenant is notified of the identity and address of Landlord’s
mortgagee or ground lessor, Tenant shall give to such mortgagee or ground lessor written notice of any default by Landlord under the terms of this Lease by overnight courier, and such mortgagee or ground lessor shall be given a reasonable
opportunity to cure such default prior to Tenant’s exercising any remedy available to Tenant.

a duly formed and existing entity qualified to do business in the state in which the Project is located 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. Tenant confirms that it is not in violation of any executive order or similar governmental regulation or law, which prohibits terrorism or transactions with suspected or confirmed terrorists or terrorist entities or with persons or
organizations that are associated with, or that provide any form of support to, terrorists. Neither Tenant nor any of its affiliates, nor to its knowledge any of their respective brokers or other agents acting in any capacity in connection with the

of the prohibitions set forth in (i) any U.S. anti-money laundering law, (ii) the Foreign Corrupt Practices Act, (iii) the U.S. mail and wire fraud statutes, (iv) the Travel Act, (v) any similar or successor statutes or
(vi) any regulations promulgated under the foregoing statutes. 
 24.22 Jury Trial; Attorneys’ Fees. TO THE
EXTENT ALLOWED UNDER APPLICABLE LAW, IF EITHER PARTY COMMENCES LITIGATION AGAINST THE OTHER FOR THE SPECIFIC PERFORMANCE OF THIS LEASE, FOR DAMAGES FOR THE BREACH HEREOF OR OTHERWISE FOR ENFORCEMENT OF ANY REMEDY HEREUNDER, THE PARTIES HERETO AGREE

 24.23 Governing
Law. This Lease shall be construed and enforced in accordance with the laws of the state in which the Project is located. 

24.24 Submission of Lease. Submission of this instrument for examination or signature by Tenant does not constitute a

24.25 Brokers. Landlord and Tenant each hereby represents and warrants to the other party that it (i) has 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 11 of the Summary (collectively, the “Brokers”), and

demands, losses, liabilities, lawsuits, judgments, and 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 the
indemnifying party’s dealings with any real estate broker or agent in connection with this Lease other than the Brokers. 

24.26 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; provided, however, that the foregoing shall in no way impair the right of Tenant to commence a separate action
against Landlord for any violation by Landlord of the provisions hereof so long as notice is first given to Landlord and any holder of a mortgage or deed of trust covering the Building, Project or any portion thereof, of whose address Tenant has
theretofore been notified, and an opportunity is granted to Landlord and such holder to correct such violations as provided above. 

24.27 Building Name and Signage. Landlord shall have the right at any time to change the name(s) of the Building, the
Other Existing Buildings and Project and to install, affix and maintain any and all signs on the exterior and on the interior of the Building, the Other Existing Buildings and any portion of the Project as Landlord may, in Landlord’s sole
discretion, desire. Tenant shall not use the names of the Building, the Other Existing Buildings or Project or use pictures or illustrations of the Building, the Other Existing Buildings or Project in advertising or other publicity, without the

Existing Buildings, limit or eliminate access to portions of the Project, including portions of the common areas, or perform work in the Building, the Other Existing Buildings and/or the Project, which work may create noise, dust or leave debris in
the Building, the Other Existing Buildings and/or the Project. Subject to Section 6.7 above, Tenant hereby agrees that such Construction and Landlord’s actions in connection with such Construction shall in no way constitute a constructive
eviction of Tenant nor entitle Tenant to any abatement of Rent. Subject to Section 6.7 above and Landlord’s indemnity obligations in this Lease, Landlord shall have no responsibility or for any reason be liable to Tenant for any direct or
indirect injury to or interference with Tenant’s business arising from such Construction, nor shall Tenant be entitled to any compensation or damages from

contractors, or licensees, Tenant hereby absolves Landlord from any and all loss, cost, damage, expense and liability, whether foreseeable or not, from any cause whatsoever, that Tenant may suffer to its personal property located anywhere in the
Hazmat Storage Space or that it or its agents, employees, principals, invitees, or licensees may suffer as a direct or indirect consequence of Tenant’s lease of or use of the Hazmat Storage Space or access areas to the Hazmat Storage Space. In
addition, Tenant hereby agrees to indemnify, defend, protect and hold Landlord harmless from and against any loss, cost, damage, liability, expense, claim, action or cause of action of any third party, whether foreseeable or not, resulting as a
direct or indirect consequence of Tenant’s lease or use of the Hazmat Storage Space or access areas to the Hazmat Storage Space. 

24.32.2 Use of Hazmat Storage Space. Tenant agrees not to store any flammable or highly combustible materials in the
Hazmat Storage Space. Tenant also agrees not to store Hazardous Material or waste in the Hazmat Storage Space except in strict accordance with Article 5 of this Lease. Tenant agrees to use the Hazmat Storage Space solely for storage purposes and not
as office space. Tenant agrees that Landlord and its agents may enter and inspect the Hazmat Storage Space and any goods stored therein at any time during regular business hours upon giving twenty-four (24) hours prior notice to Tenant and so
long as Tenant is provided with an opportunity to have a representative of Tenant present. Tenant shall, at its sole cost and expense, deliver to Landlord a key for any locks installed by Tenant for Landlord’s emergency entrance purposes.
Tenant shall accept the Hazmat Storage Space without any warranties or representations and shall maintain and repair the Hazmat Storage Space at its sole cost and expense. 

24.32.3 Assignment and Sublease. The Hazmat Storage Space may not be assigned or subleased by Tenant or otherwise
transferred by Tenant, except that Tenant may assign its rights and obligations under this Section 24.32 in connection with an assignment permissible pursuant to the terms of Article 14 of this Lease. 

24.32.4 Incorporation of Lease Provisions. The provisions of this Lease with regard to the Premises, to the extent
applicable and not inconsistent with the provisions of this Section 24.32, shall be deemed to apply to the Hazmat Storage Space as though the Hazmat Storage Space is part of the Premises. 

24.33 Communication Equipment. If Tenant desires to use the roof of the Building to install communication equipment to
be used from the Premises, Tenant may so notify Landlord in writing (“Communication Equipment Notice”), which Communication Equipment Notice shall generally describe the specifications for the equipment desired by Tenant. If at the
time of Landlord’s receipt of the Communication Equipment Notice, Landlord reasonably determines that space is available on the roof of the Building for such equipment, then subject to all governmental laws, rules and regulations, Tenant and
Tenant’s contractors (which shall first be reasonably approved by Landlord) shall have the right and access to install, repair, replace, remove, operate and maintain one (1) so-called “satellite dish” or other similar device,
such as antennae no greater than twenty (20) inches in diameter and weighing no more than fifty (50) pounds, together with all cable, wiring, conduits and related equipment (collectively, “Communication Equipment”), for
the purpose of receiving and sending radio, television, computer, telephone or other communication signals, at a location on the roof of the Building designated by Landlord. Further, Tenant shall have the right of access, consistent with this
Section 24.33, to the area where the Communication Equipment is located for the purposes of maintaining, repairing, testing and replacing the same. Landlord shall have the right to require Tenant to relocate the Communication Equipment at any
time to another location on the roof of the Building. Unless Landlord elects to perform such penetrations at Tenant’s sole cost and expense, Tenant shall retain Landlord’s designated roofing contractor to make any necessary penetrations
and associated repairs to the roof in order to preserve Landlord’s roof warranty. Tenant’s installation and operation of the Communication Equipment shall be governed by the following terms and conditions: 

24.33.1 Tenant’s right to install, replace, repair, remove, operate and maintain the Communication Equipment shall be
subject to all applicable laws and Landlord makes no representation that such Laws permit such installation and operation;

 24.33.2 All plans and specifications for the Communication Equipment shall be
subject to Landlord’s reasonable approval; 
 24.33.3 All costs of installation, operation and maintenance of the
Communication Equipment and any necessary related equipment (including, without limitation, costs of obtaining any necessary permits and connections to the Building’s electrical system) shall be borne by Tenant; 

24.33.4 It is expressly understood that Landlord retains the right to use the roof of the Building for any purpose whatsoever
(including granting rights to third parties to utilize any portion of the roof not utilized by Tenant); 
 24.33.5 Tenant
shall use the Communication Equipment so as not to cause any interference to other tenants in the Building or to other tenants at the Project or with any other tenant’s communication equipment, and not to damage the Project or interfere with
the normal operation of the Project and Tenant hereby agrees to indemnify, defend and hold Landlord harmless from and against any and all claims, costs, damages, expenses and liabilities (including attorneys’ fees) arising out of Tenant’s
failure to comply with the provisions of this Section 24.33.5, except to the extent same is caused by the gross negligence or willful misconduct of Landlord which is not covered by the insurance carried by Tenant under this Lease (or which
would not be covered by the insurance required to be carried by Tenant under this Lease); 
 24.33.6 For the purposes of
determining Tenant’s obligations with respect to its use of the roof of the Building herein provided, all of the provisions of this Lease relating to compliance with requirements as to insurance, indemnity, and compliance with laws shall apply
to the installation, use and maintenance of the Communication Equipment; provided, however, Tenant shall only be provided access to the roof after prior written notice to Landlord and subject to Landlord’s reasonable rules and restrictions
regarding access (including, at Landlord’s option, the requirement that Tenant be accompanied by a representative of Landlord during such access). Landlord shall not have any obligations with respect to the Communication Equipment. Landlord
makes no representation that the Communication Equipment will be able to receive or transmit communication signals without interference or disturbance (whether or not by reason of the installation or use of similar equipment by others on the roof of
the Building) and Tenant agrees that Landlord shall not be liable to Tenant therefor; 
 24.33.7 Tenant shall (i) be
solely responsible for any damage caused as a result of the Communication Equipment, (ii) promptly pay any tax, license or permit fees charged pursuant to any laws or regulations in connection with the installation, maintenance or use of the
Communication Equipment and comply with all precautions and safeguards recommended by all governmental authorities, and (iii) pay for all necessary repairs, replacements to or maintenance of the Communication Equipment; 

24.33.8 The Communication Equipment shall remain the sole property of Tenant. Tenant shall remove the Communication Equipment
and related equipment at Tenant’s sole cost and expense upon the expiration or sooner termination of this Lease or upon the imposition of any governmental law or regulation which may require removal, and shall repair the Building upon such
removal to the extent required by such work of removal. If Tenant fails to remove the Communication Equipment and repair the Building upon the expiration or earlier termination of this Lease, Landlord may do so at Tenant’s expense. The
provisions of this Section 24.33.8 shall survive the expiration or earlier termination of this Lease; 
 24.33.9 The
Communication Equipment shall be deemed to constitute a portion of the Premises for purposes of Article 10 of this Lease; 

24.33.10 Tenant, at Tenant’s sole cost and expense, shall install and maintain such fencing and other protective equipment
and/or visual screening on or about the Communication Equipment as Landlord may reasonably determine; 
 24.33.11 If any of
the conditions set forth in this Section 24.33 are not complied with by Tenant, then without limiting Landlord’s rights and remedies it may otherwise have under this Lease, at law and/or in equity, Tenant shall correct such noncompliance
within five (5) days after receipt of notice (or such longer period as may be reasonably required as long as Tenant commences such correction within such five (5) day period and diligently prosecutes the same to completion). If Tenant
fails to correct any such noncompliance within such five (5) day period (as may be extended), then, at Landlord’s option, Tenant shall immediately discontinue its use of such Communication Equipment and remove the same in accordance with
the terms hereof

TENANT WORK LETTER 

This Tenant Work Letter (“Tenant Work Letter”) sets forth the terms and conditions relating to the
construction of improvements for the Premises. All references in this Tenant Work Letter to the “Lease” shall mean the relevant portions of the Lease to which this Tenant Work Letter is attached as Exhibit B.

 SECTION 1 

BASE, SHELL AND CORE 

Landlord has previously constructed the base, shell and core (i) of the Premises and (ii) of the floor(s) of
the Building on which the Premises are located (collectively, with the Systems and Equipment, the “Base, Shell and Core”), and Tenant shall accept the Base, Shell and Core in its current “As-Is” condition existing as of
the date of the Lease and the Lease Commencement Date. Except for the Tenant Improvement Allowance and the Roof Allowance set forth below, Landlord shall not be obligated to make or pay for any alterations or improvements to the Premises, the
Building or the Project; provided, however, that Landlord, at Landlord’s sole cost and expense, will construct an additional elevator in the Building and shall relocate the existing 12’ x 18’ hazardous materials shed in the Project to
the approximate location depicted on Exhibit G. 
 SECTION 2 

TENANT IMPROVEMENTS 

2.1 Tenant Improvement Allowance. Tenant shall be entitled to a one-time tenant improvement allowance (the
“Tenant Improvement Allowance”) in the amount of up to, but not exceeding One Hundred Sixty-Seven Dollars ($167.00) per rentable square foot of the Premises (i.e., up to Nine Million Eight Hundred Ninety-Four Thousand Four
Hundred Sixteen Dollars ($9,894,416.00) based on 59,248 rentable square feet of the Premises), to help Tenant pay for the costs of the design, permitting and construction of Tenant’s initial improvements which are permanently affixed to the
Premises (collectively, the “Tenant Improvements”); provided, however, that Landlord shall have no obligation to disburse all or any portion of the Tenant Improvement Allowance to Tenant unless Tenant makes a request for
disbursement pursuant to the terms and conditions of Section 2.2 below prior to that date which is nine (9) months after the Lease Commencement Date. Notwithstanding anything above to the contrary, in the event there exists an
Over-Allowance Amount (as defined in Section 4.3.1 below), Tenant shall have the option, exercisable upon written notice to Landlord prior to the date Tenant is obligated to pay such Over-Allowance Amount, to receive a one-time additional
improvement allowance (the “Additional Allowance”) in the amount not to exceed Fifteen Dollars ($15.00) per rentable square foot of the Premises, (i.e., up to Eight Hundred Eighty-Eight Thousand Seven Hundred Twenty Dollars
($888,720.00) based on 59,248 rentable square feet in the Premises). In the event Tenant exercises such option and as consideration for Landlord providing such Additional Allowance to Tenant, the Base Rent payable by Tenant throughout the entire
ninety-six (96) month initial Lease Term (“Amortization Period”) shall be increased by an amount sufficient to fully amortize such Additional Allowance throughout said ninety-six (96) month period based upon equal monthly
payments of principal and interest, with interest imputed on the outstanding principal balance at the rate of nine percent (9%) per annum (the “Amortization Rent”). In the event the Lease shall terminate for any reason,
including, without limitation, as a result of a default by Tenant under the terms of the Lease or this Tenant Work Letter, Tenant acknowledges and agrees that the unamortized balance of the Additional Allowance which has not been paid by Tenant to
Landlord as of the termination date pursuant to the foregoing provisions of this Section 3, shall become immediately due and payable as unpaid rent which has been earned as of such termination date. In addition, in no event shall the
Amortization Rent be abated for any reason whatsoever. The Tenant Improvement Allowance and the Additional Allowance may collectively be referred to herein as the “Allowances.” In no event shall Landlord be obligated to make
disbursements pursuant to this Tenant Work Letter in a total amount which exceeds the Allowances. Except as otherwise provided below, Tenant shall not be entitled to receive any cash payment or credit against Rent or otherwise for any unused portion
of the Allowances which is not used to pay for the Tenant Improvement Allowance Items (as defined below); provided, however, that so long as Tenant is not in default under the Lease, (i) an amount up to One Million Four Hundred Thousand Dollars
($1,400,000.00) of the Tenant Improvement Allowance (but not the Additional Allowance) may be used for (i) cabling, furniture, fixtures and equipment purchased and installed by Tenant in the Premises as well as for relocation costs and any
termination fees in connection with Tenant’s existing lease in San Diego (collectively, the “Tenant Costs”), which shall be disbursed by Landlord within thirty (30) days of the execution of this Lease (provided, however,
that Tenant shall provide Landlord with reasonably satisfactory evidence of the termination fees and proof of payment within thirty (30) days after the same are paid by Tenant), and (ii) Four Hundred Fourteen Thousand Seven Hundred
Thirty-Six Dollars ($414,736.00) may be used as a credit toward the Base Rent due under the Lease during the first twelve (12) months following the Commencement Date. In no event shall Tenant be entitled to any credit for any unused portion of
the Additional Allowance. 
 2.2 Disbursement of the Tenant Improvement Allowance. 

2.2.1 Tenant Improvement Allowance Items. Except as otherwise set forth in this Tenant Work Letter, the Tenant
Improvement Allowance shall be disbursed by Landlord only for the following items and costs (collectively, the “Tenant Improvement Allowance Items”):

 2.2.1.1 Payment of (i) the fees of the Tenant’s Project Manager,
Architect and the Engineers (as such terms are defined below), provided, however, that only an amount not to exceed Ten Dollars ($10.00) per rentable square foot of the Premises (i.e., up to Five Hundred Ninety-Two Four Hundred Eighty
Dollars ($592,480.00) based on 59,248 rentable square feet of the Premises) may be deducted from the Tenant Improvement Allowance to pay for such fees, and (ii) the fees incurred by, and the cost of documents and materials supplied by, Landlord
and Landlord’s consultants in connection with the preparation and review of the Construction Drawings (as defined below); 

2.2.1.2 The payment of plan check, permit and license fees relating to construction of the Tenant Improvements; 

2.2.1.3 The cost of construction of the Tenant Improvements, including, without limitation, contractors’ fees and general
conditions, testing and inspection costs, costs of utilities, trash removal, parking and hoists, and the costs of after-hours freight elevator usage. 

2.2.1.4 The cost of any changes in the Base, Shell and Core work when such changes are required by the Construction Drawings
(including if such changes are due to the fact that such work is prepared on an unoccupied basis), such cost to include all direct architectural and/or engineering fees and expenses incurred in connection therewith; 

2.2.1.5 The cost of any changes to the Construction Drawings or Tenant Improvements required by applicable laws ; 

2.2.1.6 Sales and use taxes and Title 24 fees; 

2.2.1.7 The Coordination Fee (as defined below); and 

2.2.1.8 All other costs to be expended by Landlord in connection with the design, permitting and construction of the Tenant
Improvements. 
 2.3 Specifications for Building Standard Components. The standard components to be used in the
construction of the Tenant Improvements in the Premises shall be no less comparable to those commonly found in other biotechnology projects in San Diego County. 

2.4 Roof Allowance. Notwithstanding anything to the contrary contained herein, Tenant shall, during the period prior to
the Lease Commencement Date, have the right to perform Landlord approved Building roof repairs and Building roof replacement work (“Roof Work”) in accordance with this Section 2.4 and otherwise in accordance with Article 8 of
the Lease. In connection therewith, Tenant shall, so long as no default exists under the Lease beyond applicable notice and cure period, be entitled to a one-time tenant refurbishment allowance (the “Roof Allowance”) in the amount
up to, but not exceeding, Seventy-Five Thousand Dollars ($75,000.00) for the costs of the Roof Work. In no event shall Landlord be obligated to make disbursements under this Section 2.4 in a total amount which exceeds the Roof Allowance. As
provided below, Tenant is required to utilize the Roof Allowance on or before the Lease Commencement Date, and if Tenant fails to use the Roof Allowance prior to such date, then the Roof Allowance shall not be available to Tenant. 

2.4.1 Roof Allowance Items. the Roof Allowance shall be disbursed by Landlord following completion of the Roof Work for the
following items and costs only (collectively, the “Roof Allowance Items”); 
 (a) Payment of the fees of the
architect and engineer(s) retained by Tenant (if any), and payment of the fees incurred by, and the cost of documents and materials supplied by, Landlord and Landlord’s consultants in connection with the review of the plans and specifications
prepared for the Roof Work (“Drawings”); 
 (b) the payment of plan check, permit and license fees relating to
construction of the Roof Work; 
 (c) The cost of construction of the Roof Work including, without limitation, testing and
inspection costs, trash removal costs, and contractors’ fees and general conditions; and 
 (d) Sales and use taxes.

 2.4.2 Disbursement of Roof Allowance. Provided that Tenant is not in default under the Lease beyond the expiration
of applicable notice and cure periods, upon completion of the Roof Work, Landlord shall make a disbursement of the Roof Allowance for the Roof Allowance Items for the benefit of Tenant and shall authorize the release of monies for the benefit of
Tenant as follows: 
 (a) Disbursement. Tenant shall deliver to Landlord: (i) a request for payment of
Tenant’s general contractor (“Tenant’s Contractor”), which Tenant’s Contractor shall be retained by Tenant and shall be subject to Landlord’s reasonable prior written approval, which approval shall not be
unreasonably withheld, conditioned or delayed (and with Landlord hereby pre-approving Arithane as Tenant’s Contractor), and which request shall be approved by Tenant, in a form to be provided by Landlord; (ii) paid invoices from all
subcontractors, laborers, materialmen and suppliers used by Tenant in connection with the Roof Work (such subcontractors, laborers, materialmen and suppliers, and the Tenant’s Contractor may be known collectively as


  

					
	                 
	  	 EXHIBIT B

“Tenant’s Agents”), for labor rendered and materials delivered for such Roof Work; (iii) executed unconditional mechanics’ lien releases from all of Tenant’s
Agents in such form and content as reasonably required by Landlord; and (iv) all other information reasonably requested by Landlord. Tenant’s request for payment shall be deemed Tenant’s acceptance and approval of the work furnished
and/or the materials supplied as set forth in Tenant’s payment request except for punch list items. Within thirty (30) days after Landlord’s receipt of the applicable information described in items (i) through (iv) above,
Landlord shall deliver a check made payable to Tenant or Tenant’s Contractor, as directed by Tenant, in payment of the amounts so requested by Tenant (but in no event to exceed the amount of the Roof Allowance), provided that Landlord does not
dispute any request for payment based on non-compliance of any work with the Drawings, or due to any substandard work. Landlord’s payment of such amounts shall not be deemed Landlord’s approval or acceptance of the work furnished or
materials supplied as set forth in Tenant’s payment request. 
 (b) Other Terms. Landlord shall only be
obligated to make disbursements from the Roof Allowance to the extent costs are incurred by Tenant for the Roof Allowance Items. All costs of any Roof Work in excess of the Roof Allowance or any other roof work necessitated due to Tenant’s Roof
Work, shall be Tenant’s responsibility at Tenant’s sole cost and expense. All Roof Allowance Items for which the Roof Allowance has been made available shall be deemed Landlord’s property. All drafts of the Drawings (which Drawings
shall also include materials and specifications for the Roof Work) shall be subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed. In addition, all of Tenant’s Agents shall
be subject to Landlord’s prior written approval (which approval shall not be unreasonably withheld, conditioned or delayed). Notwithstanding anything in this Section 2.4 to the contrary, (i) in no event will Tenant be entitled to
receive any portion of the Roof Allowance after the Lease Commencement Date (and as long as Tenant, with respect to any improvements for which Tenant seeks reimbursement, has complied with the requirements of Section 2.4.2(a) above on or before
such date). Tenant shall obtain commercially reasonable warranties for any such Roof Work and such warranties shall be assigned to Landlord, which assignment shall be on a non-exclusive basis so that the warranties may be enforced by Landlord and
Tenant. 
 SECTION 3 

CONSTRUCTION DRAWINGS 

3.1 Selection of Project Manager and Architect/Construction Drawings. Tenant shall select a project manager to assist
Tenant with Tenant’s obligations regarding the design and construction of the Tenant Improvements (the “Project Manager”), which Project Manager shall be subject to Landlord’s reasonable approval. Landlord shall retain an
architect/space planner (the “Architect”) selected by Tenant to prepare the “Construction Drawings,” as that term is defined in this Section 3.1, which Architect shall be subject to Landlord’s reasonable
approval; provided, however, that the following Architect, if selected by Tenant, is hereby deem pre-approved by Landlord: DGA. Landlord shall retain Landlord’s engineering consultants (the “Engineers”) to work with Tenant to
prepare all plans and engineering working drawings relating to the structural, mechanical, electrical, plumbing, HVAC, lifesafety, and sprinkler work in the Premises, which Engineers shall be selected by Tenant, subject to Landlord’s reasonable
approval; provided, however, that the following Engineers, if selected by Tenant, are hereby deemed pre-approved by Landlord: Michael Wall Engineering and Creo Engineering. The plans and drawings to be prepared by Architect and the Engineers
hereunder shall be known collectively as the “Construction Drawings.” Notwithstanding that any Construction Drawings are reviewed by Landlord or prepared by its Architect, Engineers and consultants, and notwithstanding any advice or
assistance which may be rendered to Tenant by Landlord or Landlord’s Architect, Engineers, and consultants, Landlord shall have no liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained
in the Construction Drawings, and Tenant’s waiver and indemnity set forth in Article 10 of the Lease shall specifically apply to the Construction Drawings. 

3.2 Final Space Plan. Within five (5) days of the full execution and delivery of the Lease by Landlord and
Tenant, Tenant shall meet with Landlord’s Architect and provide Landlord’s Architect with information regarding the preliminary layout and designation of all proposed offices, rooms and other partitioning, and their intended use and
equipment to be contained therein (the “Information”). Landlord shall cause Architect to, based on such Information (subject to changes reasonably required by Landlord), to work with Tenant to prepare the final space plan for Tenant
Improvements in the Premises (collectively, the “Final Space Plan”), which Final Space Plan shall include a layout and designation of all offices, rooms and other partitioning, their intended use, and equipment to be contained
therein, and to deliver the Final Space Plan to Tenant for Tenant’s approval. Tenant shall approve or reasonably disapprove the Final Space Plan or any revisions thereto within five (5) business days after Landlord delivers the Final Space
Plan or such revisions to Tenant; provided, however, that Tenant may only disapprove the Final Space Plan to the extent the same is not (subject to changes reasonably required by Landlord) in substantial conformance with the Information provided by
Tenant to Architect (“Space Plan Design Problem”) unless Tenant agrees in writing that any changes requested by Tenant (and the processing of such changes even if they are not implemented) will be a Tenant Delay. Tenant’s
failure to disapprove the Final Space Plan for any Space Plan Design Problem or any revisions thereto by written notice to Landlord (which notice shall specify in detail the reasonable reasons for Tenant’s disapproval pertaining to any Space
Plan Design Problem) within said five (5) business day period shall be deemed to constitute Tenant’s approval of the Final Space Plan or such revisions. 

3.3 Final Working Drawings. Based on the Final Space Plan, Landlord shall cause the Architect and the Engineers to
complete the architectural and engineering drawings for the Premises, and cause the Architect to compile a fully coordinated set of architectural, structural, mechanical, electrical and plumbing working drawings in a form which is complete to allow
subcontractors to bid on the work and to obtain all applicable permits (collectively, the “Final Working Drawings”) and shall submit the same to Tenant for Tenant’s approval. The Final


  

					
	                 
	  	 EXHIBIT B

	  	 TORREY RIDGE SCIENCE CENTER

Regulus Therapeutics










 
Working Drawings shall incorporate modifications to the Final Space Plan as necessary to comply with the floor load and other structural and system requirements of the Building. To the extent
that the finishes and specifications are not completely set forth in the Final Space Plan for any portion of the Tenant Improvements depicted thereon, the actual specifications and finish work shall be in accordance with the Specifications. Tenant
shall approve or reasonably disapprove the Final Working Drawings or any revisions thereto within five (5) business days after Landlord delivers the Final Working Drawings or any revisions thereto to Tenant; provided, however, that Tenant may
only disapprove the Final Working Drawings to the extent the same are not (subject to changes reasonably required by Landlord) in substantial conformance with the Final Space Plan (“Working Drawing Design Problem”) unless Tenant
agrees in writing that any changes requested by Tenant (and the processing of such changes even if they are not implemented) shall be deemed a Tenant Delay. Tenant’s failure to reasonably disapprove the Final Working Drawings or any revisions
thereto by written notice to Landlord (which notice shall specify in detail the reasonable reasons for Tenant’s disapproval pertaining to any Working Drawing Design Problem) within said five (5) business day period shall be deemed to
constitute Tenant’s approval of the Final Working Drawings or such revisions. 
 3.4 Approved Working
Drawings. The Final Working Drawings shall be approved or deemed approved by Tenant (the “Approved Working Drawings”) prior to the commencement of the construction of the Tenant Improvements. Landlord shall cause the Architect
to submit the Approved Working Drawing to the applicable local governmental agency for all applicable building permits necessary to allow the Contractor (as defined below), to commence and fully complete the construction of the Tenant Improvements
(the “Permits”). No changes, modifications or alterations in the Approved Working Drawings may be made without the prior written consent of Landlord. 

3.5 Time Deadlines. Tenant shall use its best efforts to cooperate with Architect, the Engineers, and Landlord to
complete all phases of the Construction Drawings and the permitting process and to receive the Permits, and with the Contractor, for approval of the Cost Proposal (as defined below) as soon as possible after the execution of the Lease and, in this
regard, to the extent Landlord considers such meeting(s) to be reasonably necessary, Tenant shall meet with Landlord on a weekly basis to discuss Tenant’s progress in connection with the same. 

3.6 Change Orders. In the event that Tenant desires to make any changes to the Approved Working Drawings, any such
changes shall be subject to Landlord’s approval, which approval shall not be unreasonably withheld. Landlord shall, within three (3) business days after Landlord receives Tenant’s request for any such change, either reasonably approve
such change or reasonably disapprove such change, in which case Landlord shall notify Tenant of Landlord’s reason for such disapproval. If Landlord fails to disapprove such change within said three (3) business day period and if such
failure continues for one (1) additional business day after Tenant’s second request for approval, such change shall be deemed to be approved by Landlord. Concurrently with Tenant’s delivery of the change request to Landlord, Tenant
shall also deliver such change request to Contractor. The Contractor shall be requested to provide an estimate of the change in cost associated with such change and an estimate of the impact on the construction schedule resulting from such change.
Such information shall be provided to Tenant and Tenant shall be provided with an opportunity to either proceed with such change based upon such information or to rescind its request for such change; however, whether or not Tenant requests a
rescission of such change, to the extent there is delay in the Substantial Completion of the Tenant Improvements in the Premises as a result of such process, such delay shall be deemed to constitute a Tenant Delay. 

SECTION 4 

CONSTRUCTION OF THE TENANT IMPROVEMENTS 

4.1 Contractor. Tenant has selected (and Landlord hereby approves) Rudolf Sletten as the contractor to be retained by
Landlord to construct the Tenant Improvements (the “Contractor”). 
 4.2 Cost Proposal. After
the Approved Working Drawings are signed by Landlord and Tenant, Landlord shall provide Tenant with a cost proposal in accordance with the Approved Working Drawings, which cost proposal shall include, as nearly as possible, the cost of all Tenant
Improvement Allowance Items to be incurred by Tenant in connection with the construction of the Tenant Improvements (the “Cost Proposal”). Tenant shall approve and deliver the Cost Proposal to Landlord within five (5) business
days after Tenant’s receipt thereof. The date by which Tenant must approve and deliver the Cost Proposal shall be known hereafter as the “Cost Proposal Delivery Date 

 

	4.3	 Construction of Tenant Improvements by Landlord’s Contractor under the Supervision of Landlord. 



4.3.1 Over-Allowance Amount. On the Cost Proposal Delivery Date, Tenant shall deliver to Landlord cash in an amount (the
“Over-Allowance Amount”) equal to the difference between (i) the amount of the Cost Proposal and (ii) the amount of the Allowances (less any portion thereof already disbursed by Landlord, or in the process of being
disbursed by Landlord, on or before the Cost Proposal Delivery Date and subject to the Additional Allowance). The Over-Allowance Amount shall be disbursed by Landlord prior to the disbursement of any then remaining portion of the Allowances, and
such disbursement shall be pursuant to the same procedure as the Tenant Improvement Allowance. If, after the Cost Proposal Date, any revisions, changes, or substitutions shall be made to the Construction Drawings or the Tenant Improvements, any
additional costs which arise in connection with such revisions, changes or substitutions shall be added to the Cost Proposal and shall be paid by Tenant to Landlord within five (5) business days after Landlord’s request therefor to the
extent such additional costs increase any existing Over-Allowance Amount or result in an Over-Allowance Amount. Following completion of the Tenant

Improvements, Landlord shall deliver to Tenant a final cost statement which shall indicate the final costs of the Tenant Improvement Allowance Items, and if such cost statement indicates that
Tenant has underpaid or overpaid the Over-Allowance Amount, then within ten (10) business days after Tenant’s receipt of such statement, Tenant shall deliver to Landlord the amount of such underpayment or Landlord shall return to Tenant
the amount of such overpayment, as the case may be. 
 4.3.2 Landlord Supervision. After Landlord retains the
Contractor, Landlord shall independently retain the Contractor to construct the Tenant Improvements in accordance with the Approved Working Drawings and Landlord shall supervise the construction by the Contractor, and Tenant shall pay a construction
supervision and management fee (the “Landlord Supervision Fee”) to Landlord in an amount equal to the product of (i) two and one-half percent (2.5%) and (ii) all of the so-called “hard” construction costs
(not including costs related to the Architect, Engineer, permits and other so-called “soft” construction costs) to construct the Tenant Improvements. 

4.3.3 Contractor’s Warranties and Guarantees. Landlord hereby assigns to Tenant all warranties and guarantees by
Contractor relating to the Tenant Improvements, which assignment shall be on a non-exclusive basis such that the warranties and guarantees may be enforced by Landlord and/or Tenant, and Tenant hereby waives
all claims against Landlord relating to, or arising out of the construction of, the Tenant Improvements. 
 SECTION 5 

SUBSTANTIAL COMPLETION; 

LEASE COMMENCEMENT DATE 

5.1 Substantial Completion. For purposes of the Lease, including for purposes of determining the Lease Commencement Date
(as set forth in Section 7.2 of the Summary), the Premises shall be “Ready for Occupancy” upon Substantial Completion of the Premises. For purposes of this Lease, “Substantial Completion” of the Premises shall
occur upon (i) the completion of construction of the Tenant Improvements in the Premises pursuant to the Approved Working Drawings, with the exception of any punchlist items (that do not materially adversely affect Tenant’s use and
occupancy of the Premises) and any tenant fixtures, work-stations, built-in furniture, or equipment to be installed by Tenant or under the supervision of Contractor and (ii) the issuance by the City of San Diego of a temporary certificate of
occupancy for the Premises (or its functional equivalent). Notwithstanding anything in this Lease to the contrary, in no event shall the absence of any operational governmental approvals/certifications pertaining to operating any lab/testing systems
in the Premises affect the occurrence of the Lease Commencement Date. 
 5.2 Tenant Delays. If there shall be a delay
or there are delays in the Substantial Completion of the Premises (as a direct, indirect, partial, or total result of any of the following (collectively, “Tenant Delays”): 

5.2.1 Tenant’s failure to timely approve any matter requiring Tenant’s approval, including a Partial Cost Proposal or
the Cost Proposal and/or Tenant’s failure to timely perform any other obligation or act required of Tenant hereunder; 

5.2.2 a breach by Tenant of the terms of this Tenant Work Letter or the Lease; 

5.2.3 Tenant’s request for changes in the Construction Drawings; 

5.2.4 Tenant’s requirement for materials, components, finishes or improvements which are not available in a commercially
reasonable time (based upon the anticipated date of the Lease Commencement Date) or which are different from, or not included in, the Specifications; 

5.2.5 changes to the Base, Shell and Core required by the Approved Working Drawings; 

5.2.6 any changes in the Construction Drawings and/or the Tenant Improvements required by applicable laws if such changes are
directly attributable to Tenant’s use of the Premises or Tenant’s specialized tenant improvement(s) (as determined by Landlord); or 

5.2.7 any other acts or omissions of Tenant, or its agents, or employees; 

then, notwithstanding anything to the contrary set forth in the Lease and regardless of the actual date of the Substantial
Completion of the Premises, the Lease Commencement Date (as set forth in Section 7.2 of the Summary) shall be deemed to be the date the Lease Commencement Date would have occurred if no Tenant Delay or Delays, as set forth above, had occurred.

 5.3 Landlord’s Approvals. Landlord agrees to use commercially reasonable efforts to minimize any delays in the
construction of the Tenant Improvements that are within its control and to respond to any reasonable requests for approvals in connection with the Tenant Improvements (and which are not inconsistent with the terms of this Tenant Work Letter) in a
reasonably timely fashion.

 SECTION 6 

MISCELLANEOUS 

6.1 Tenant’s Entry Into the Premises Prior to Substantial Completion. Subject to the terms hereof and provided that
Tenant and its agents do not interfere with, or delay, Contractor’s work in the Project, the Building and the Premises, at Landlord’s reasonable discretion, Landlord shall use commercially reasonable efforts to allow Tenant access to the
Premises at least thirty (30) days prior to the Substantial Completion of the Premises for the purpose of Tenant installing equipment and/or fixtures (including Tenant’s data and telephone equipment) in the Premises. Prior to Tenant’s
entry into the Premises as permitted by the terms of this Section 6.1, Tenant shall submit a schedule to Landlord and Contractor, for their approval, which schedule shall detail the timing and purpose of Tenant’s entry. In connection with
any such entry, Tenant acknowledges and agrees that Tenant’s employees, agents, contractors, consultants, workmen, mechanics, suppliers and invitees shall fully cooperate, work in harmony and not, in any manner, interfere with Landlord or
Landlord’s Contractor, agents or representatives in performing work in the Project, the Building and the Premises, or interfere with the general operation of the Building and/or the Project. If at any time any such person representing Tenant
shall not be cooperative or shall otherwise cause or threaten to cause any such disharmony or interference, including, without limitation, labor disharmony, and Tenant fails to immediately institute and maintain corrective actions as directed by
Landlord, then Landlord may revoke Tenant’s entry rights upon twenty-four (24) hours’ prior written notice to Tenant. Tenant acknowledges and agrees that any such entry into and occupancy of the Premises or any portion thereof by
Tenant or any person or entity working for or on behalf of Tenant shall be deemed to be subject to all of the terms, covenants, conditions and provisions of the Lease, excluding only the covenant to pay Rent (until the occurrence of the Lease
Commencement Date). Tenant further acknowledges and agrees that Landlord shall not be liable for any injury, loss or damage which may occur to any of Tenant’s work made in or about the Premises in connection with such entry or to any property
placed therein prior to the Lease Commencement Date, the same being at Tenant’s sole risk and liability. Tenant shall be liable to Landlord for any damage to any portion of the Premises, including the Tenant Improvement work, caused by Tenant
or any of Tenant’s employees, agents, contractors, consultants, workmen, mechanics, suppliers and invitees. If the performance of Tenant’s work in connection with such entry causes extra costs to be incurred by Landlord or requires the use
of any Building services, Tenant shall promptly reimburse Landlord for such extra costs and/or shall pay Landlord for such Building services at Landlord’s standard rates then in effect. In addition, 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 6.1. 

6.2 Tenant’s Representative. Tenant has designated David Szekeres as its sole representative with respect to the
matters set forth in this Tenant Work Letter, who shall have full authority and responsibility to act on behalf of the Tenant as required in this Tenant Work Letter. 

6.3 Landlord’s Representative. Landlord has designated Samantha Page as its sole representative with respect to the
matters set forth in this Tenant Work Letter, who, until further notice to Tenant, shall have full authority and responsibility to act on behalf of the Landlord as required in this Tenant Work Letter. 

6.4 Time of the Essence in This Tenant Work Letter. Unless otherwise indicated, all references herein to a “number
of days” shall mean and refer to calendar days. In all instances where Tenant is required to approve or deliver an item, if no written notice of approval is given or the item is not delivered within the stated time period, at Landlord’s
sole option, at the end of said period the item shall automatically be deemed approved or delivered by Tenant and the next succeeding time period shall commence. 

6.5 Tenant’s Lease Default. Notwithstanding any provision to the contrary contained in the Lease, if an event of
default by Tenant as described in Section 19.1 of the Lease or any default by Tenant under this Tenant Work Letter has occurred at any time on or before the Substantial Completion of the Premises, then (i) in addition to all other rights
and remedies granted to Landlord pursuant to the Lease, at law and/or in equity, Landlord shall have the right to withhold payment of all or any portion of the Tenant Improvement Allowance and/or Landlord may cause Contractor to suspend the
construction of the Premises (in which case, Tenant shall be responsible for any delay in the Substantial Completion of the Premises caused by such work stoppage as a Tenant Delay as set forth in Section 5.2 above), and (ii) all other
obligations of Landlord under the terms of this Tenant Work Letter shall be forgiven until such time as such default is cured pursuant to the terms of the Lease (in which case, Tenant shall be responsible for any delay in the Substantial Completion
of the Premises caused by such inaction by Landlord). In addition, if the Lease is terminated prior to the Lease Commencement Date, for any reason due to a default by Tenant as described in Section 19.1 of the Lease or under this Tenant Work
Letter, in addition to any other remedies available to Landlord under the Lease, at law and/or in equity, Tenant shall pay to Landlord, as Additional Rent under the Lease, within five (5) business days after Tenant’s receipt of a statement
therefor, any and all costs incurred by Landlord (including any portion of the Tenant Improvement Allowance disbursed by Landlord) and not reimbursed or otherwise paid by Tenant through the date of such termination in connection with the Tenant
Improvements to the extent planned, installed and/or constructed as of such date of termination, including, but not limited to, any costs related to the removal of all or any portion of the Tenant Improvements and restoration costs related thereto.

No boring or cutting for wires shall be allowed without the consent of Landlord. The location of telephone, call boxes and other office equipment and/or systems affixed to the Premises shall be subject to the approval of Landlord.

shall take the actions necessary to resolve the Labor Disruption, and shall have pickets removed and, at the request of Landlord, immediately terminate any work in the Premises that gave rise to the Labor Disruption, until Landlord gives its written
consent for the work to resume, and Tenant shall have no claim for damages against Landlord or any of its trustees, members, principals, beneficiaries, partners, officers, directors, employees, mortgagees, or agents in connection therewith.

be left unattended in any Common Areas. 
 33. Landlord shall have the right to prohibit the use of the name of the Building
or Project or any other publicity by Tenant that in Landlord’s sole opinion may impair the reputation of the Building or Project or the desirability thereof. Upon written notice from Landlord, Tenant shall refrain from and discontinue such
publicity immediately. 
 34. Landlord shall have the right to designate and approve standard window coverings for the
Premises and to establish rules to assure that the Building presents a uniform exterior appearance. Tenant shall ensure, to the extent reasonably practicable, that window coverings are closed on windows in the Premises while they are exposed to the
direct rays of the sun. 
 35. The work of cleaning personnel shall not be hindered by Tenant after 5:30 P.M., and cleaning
work may be done at any time when the offices are vacant. Windows, doors and fixtures may be cleaned at any time. Tenant shall provide adequate waste and rubbish receptacles to prevent unreasonable hardship to the cleaning service.

Tenant’s inability to use the parking spaces will not subject Landlord (and/or the Parking Operator, as the case may be) to any liability to Tenant

 Tenant shall be
responsible for the observance of all of the Rules and Regulations and Parking Rules and Regulations in this Exhibit D by Tenant’s employees, agents, clients, customers, invitees and guests. Landlord may waive any one or more of the

of any other tenant or tenants, nor prevent Landlord from thereafter enforcing any such Rules or Regulations and/or Parking Rules and Regulations against any or all tenants of the Building and/or the Project. Landlord reserves the right at any time
to change or rescind any one or more of these Rules and Regulations and/or the Parking Rules and Regulations, or to make such other and further reasonable Rules and Regulations and/or Parking Rules and Regulations as in Landlord’s judgment may
from time to time be necessary for the management, safety, care and cleanliness of the Premises, Building and Project, and for the preservation of good order therein, as well as for the convenience of other occupants and tenants therein. Tenant

 EXHIBIT E 

INSURANCE REQUIRED OF CONTRACTORS 

1. Required Insurance. Contractor shall maintain the following insurance without interruption through final completion,
at any time thereafter when Contractor enters the site to perform work, and during any additional periods specified herein: 

(a) Commercial general liability insurance on the current ISO CG 00 01 occurrence form or an equivalent acceptable to
Owner (the “CGL”), [look at the following, grammatically] (i) covering liability arising from premises operations, independent contractors, products-completed operations, personal and advertising injury, and liability assumed
under an insured contract (including the tort liability of another assumed in a business contract), (ii) with limits of not less than $1,000,000 each occurrence, $1,000,000 personal and advertising injury, $2,000,000 general aggregate, and a
separate $2,000,000 products-completed operations aggregate, (iii) including the Additional Insureds (as defined in Section 6 of this Exhibit) as additional insureds, using one or more additional insured endorsements (such as a combination
of CG 20 10 (or CG 20 15 for vendors) and CG 20 37) that provides coverage for both ongoing and completed operations and is acceptable to Owner, (iv) that applies as primary and non-contributing insurance with respect to any other
insurance or self-insurance program afforded to the Additional Insureds, (v) that provides that any general aggregate limit applies separately to the work on a “per project” basis, (vi) that does not limit the scope of coverage
for liability arising from “XCU” (explosion, collapse, or underground) hazards, and (vii) that includes a standard ISO separation of insureds provision or a substantially similar provision. Contractor shall maintain its
products-completed operations coverage for at least three years after substantial completion of the work or the earlier termination of the Lease. 

(b) Business automobile liability insurance to cover liability arising out of any auto (including owned, hired and
non-owned autos), with a limit of not less than $1,000,000 each accident. Contractor waives all rights against the Additional Insureds for recovery of damages to the extent those damages are covered under its business automobile liability insurance
(and, if applicable, commercial excess or umbrella liability insurance). 
 (c) Workers compensation and employers
liability insurance, for all persons Contractor employs in carrying out any work. The workers compensation insurance must fulfill applicable statutory requirements. The employers liability insurance must have limits of not less than $1,000,000
each accident for bodily injury by accident, $1,000,000 each employee for bodily injury by disease, and $1,000,000 policy limit for bodily injury by disease. Contractor waives all rights against Landlord for recovery of damages covered by the
workers compensation and employers liability insurance obtained by Contractor, and shall obtain an endorsement to allow this waiver. If Contractor uses borrowed employees (including employees from a temporary employment agency) to perform work, it
shall require the primary employer to provide an alternate employer endorsement showing Contractor in the schedule as the alternate employer. 

(d) Commercial excess or umbrella liability insurance with respect to Contractor’s CGL, business auto liability,
and employers liability insurance, with a limit of not less than $3,000,000 each occurrence. This insurance must be “true follow form,” must include the Additional Insureds as additional insureds with respect to Contractor’s CGL, must
apply on a primary and noncontributing basis with respect to any other insurance or self-insurance program afforded to the Additional Insureds, and must provide that aggregate limits of liability apply separately with respect to the work. 

2. Insurance Carried by Subcontractors. Contractor shall by written agreement require each of its subcontractors and
consultants of every tier (“Subcontractors”) to maintain as if they were “Contractor” the insurance required in Section 1 (including naming the Additional Insureds as additional insureds), except that for
Subcontractors with a contract value of less than $50,000 that are performing minor and non-hazardous work Contractor may, in its reasonable business judgment, (a) permit auto insurance limits of not less than $500,000 each accident, and
(b) permit employers liability limits of not less than $500,000 per type of claim, (c) waive the requirement for a waiver of subrogation for workers compensation and employers liability insurance, and (d) waive the requirement for
commercial excess or umbrella liability insurance. 
 3. Design Services or Design-Build Services. If any portion of
the work includes any design services or design-build work, the entity or individual providing the design services shall provide professional liability insurance with a limit of not less than $1,000,000 each claim and $1,000,000 aggregate. This
insurance must be retroactive to the date of the commencement of the design services, and must be maintained for three years after substantial completion of the work or the earlier termination of the Lease. 

4. General Requirements. Each insurance policy required under this Exhibit E (together with the other requirements of
this Exhibit E, the “Required Insurance”) must, unless otherwise agreed in writing by Landlord, be issued by reputable insurance carriers having a Best’s rating of at least A- VIII. Each policy and certificate will be subject
to reasonable approval by Landlord, and Contractor shall deliver to Landlord certified copies of policies within 15 days after Landlord’s request. Except as may be specifically provided in this Agreement, the cost (including deductibles and
self-insured retentions) of the Required Insurance, as well as the cost of any other insurance carried by Contractor with respect to the work, will be borne solely by Contractor, without additional reimbursement by Landlord. By requiring the
Required Insurance, Landlord does not represent that the required coverage and limits will be adequate to protect Contractor, and unless otherwise specifically provided in the Lease the required coverage and limits will not limit Contractor’s
other obligations under the Lease.

 5. Evidence of Insurance. Concurrently with the execution of the Lease,
and in any event before commencing work at the site, Contractor shall provide to Landlord (i) an insurance certificate evidencing the Required Insurance, and (ii) an endorsement to Contractor’s CGL adding the Additional Insureds as
additional insureds. Contractor shall ensure that Landlord is notified at least 30 days before the cancellation or non-renewal of any Required Insurance, or 10 days prior in the case of cancellation due to non-payment. Contractor shall provide an
updated certificate of insurance before the expiration of the term of any Required Insurance. Landlord’s failure to require Contractor to provide evidence of Required Insurance, or Landlord’s acceptance of evidence that indicates insurance
that fails to satisfy the requirements of this Exhibit E, will not constitute a waiver of those requirements. 
 6.
Additional Insureds. The “Additional Insureds” are as follows: all individuals and entities that have any direct or indirect interest in Landlord; any holders of indebtedness secured by the Project; Tenant (if this is a
build-out) and any entities that Landlord, per any other project-related agreement, is required to list as an additional insured, and, with respect to each of the foregoing, its managers, officers, directors, employees, and agents. 

7. Risk of Loss; Property Insurance. Except to the extent a loss is covered by applicable insurance, Contractor bears
the risk of loss and damage to the work (including any materials incorporated or to be incorporated as part of the work) until the date when the work is completed. Contractor and its Subcontractors are responsible to carry, at their own expense,
property insurance covering the full replacement value of their machinery, tools, and equipment, and of work (including materials) until the risk of loss for Work passes to Landlord. To the fullest extent permitted by law Contractor hereby waives,
and shall require Subcontractors (including equipment lessors) to waive, all claims against Landlord, the other Additional Insureds, tenants at the Project, and Landlord’s separate contractors and consultants and their subcontractors and
subconsultants, for loss or damage to these items, regardless of the cause.

 RIDER 

EXTENSION OPTION RIDER 

This Extension Option Rider (“Extension Rider”) is attached to and made a part of the Lease by and
between Landlord and Tenant. The agreements set forth in this Extension Rider shall have the same force and effect as if set forth in the Lease. To the extent the terms of this Extension Rider are inconsistent with the terms of the Lease, the terms
of this Extension Rider shall control. 
 1. Extension Option. Landlord hereby grants Tenant option (the
“Extension Option”) to extend the Lease Term for a period of five (5) years (the “Option Term”), which option shall be exercisable only by written Exercise Notice (as defined below) delivered by Tenant to
Landlord as provided below. Upon the proper exercise of the Extension Option, the Lease Term shall be extended for the Option Term. Notwithstanding the foregoing, at Landlord’s option, in addition to any other remedies available to Landlord
under the Lease, at law or in equity, the Extension Option shall not be deemed properly exercised if as of the date of delivery of the Exercise Notice (as defined below) by Tenant is in default under the Lease beyond all applicable notice and cure
periods. The Extension Option is personal to the Original Tenant and any Affiliate Assignee and may only be exercised by the Original Tenant or any Affiliate Assignee (and not any other assignee, sublessee or other transferee of Tenant’s
interest in the Lease) if the Original Tenant or any Affiliate Assignee occupies the entire Premises as of the date of Tenant’s delivery of the Exercise Notice. 

2. Option Rent. The annual Base Rent payable by Tenant during the Option Term (the “Option
Rent”) shall be equal to the Fair Market Rental Rate for the Premises. As used herein, the “Fair Market Rental Rate” shall mean the annual base rent at which tenants, as of the commencement of the Option Term, will be
leasing non-sublease space comparable in size, location (including views) and quality to the Premises for a comparable term as the Option Term, which comparable space is located in the Building, the Other Existing Buildings in the Project and in
other comparable first-class biotechnology buildings in San Diego County, taking into consideration all free rent and other out-of-pocket concessions generally being granted at such time for such comparable space for the Option Term (including,
without limitation, any tenant improvement allowance provided for such comparable space, with the amount of such tenant improvement allowance to be provided for the Premises during the Option Term to be determined after taking into account the age,
quality and layout of the tenant improvements in the Premises as of the commencement of the Option Term with consideration given to the fact that the improvements existing in the Premises are specifically suitable to Tenant). All other terms and
conditions of the Lease shall apply throughout the Option Term; however, Tenant shall, in no event, have the option to extend the Lease Term beyond the Option Term described in Section 1 above. 

3. Exercise of Option. The Extension Option shall be exercised by Tenant, if at all, only in the following manner: if
Tenant wishes to exercise the Extension Option, Tenant shall, on or before the date (the “Exercise Date”) which is ten (10) months prior to the expiration of the initial Lease Term, exercise the Extension Option by delivering
written notice (“Exercise Notice”) thereof to Landlord. Tenant’s failure to deliver the Exercise Notice on or before such date shall be deemed to constitute Tenant’s waiver of the Extension Option. 

4. Determination of Option Rent. If Tenant objects to the Fair Market Rental Rate for the Option Term proposed by
Landlord in response to Tenant’s Exercise Notice, then Landlord and Tenant shall attempt in good faith to agree upon the Fair Market Rental Rate. If Landlord and Tenant fail to reach agreement within ten (10) business days following the
later of (i) that date which is nine (9) months prior to the expiration of the initial Lease Term or (ii) Tenant’s delivery of such Exercise Notice (the “Outside Agreement Date”), then each party shall submit to
the other party a separate written determination of the Fair Market Rental Rate within fifteen (15) business days after the Outside Agreement Date, and such determinations shall be submitted to arbitration in accordance with the provisions of
Sections 4.1 through 4.7 below. The failure of Tenant to submit a written determination of the Fair Market Rental Rate within such fifteen (15) business day period shall conclusively be deemed to be Tenant’s approval of the Fair Market
Rental Rate submitted within such fifteen (15) business day period by the other party. 
 4.1 Landlord and Tenant shall
each appoint one (1) arbitrator who shall by profession be an independent real estate broker who shall have no ongoing relationship with Tenant or Landlord and who shall have been active over the five (5) year period ending on the date of
such appointment in the leasing of first class office buildings in the Torrey Pines area of San Diego County. The determination of the arbitrators shall be limited solely to the issue of whether Landlord’s or Tenant’s submitted Fair Market
Rental Rate is the closer to the actual Fair Market Rental Rate as determined by the arbitrators, taking into account the requirements with respect thereto set forth in Section 2 above. Each such arbitrator shall be appointed within fifteen
(15) days after the Outside Agreement Date. 
 4.2 The two (2) arbitrators so appointed shall, within fifteen
(15) days of the date of the appointment of the last appointed arbitrator, agree upon and appoint a third arbitrator who shall be qualified under the same criteria set forth hereinabove for qualification of the initial two (2) arbitrators.

 4.3 The three (3) arbitrators shall, within thirty (30) days of the appointment of the third arbitrator, reach a
decision as to which of Landlord’s or Tenant’s submitted Fair Market Rental Rate is closer to the actual Fair Market Rental Rate and shall select such closer determination as the Fair Market Rental Rate and notify Landlord and Tenant
thereof. 
 4.4 The decision of the majority of the three (3) arbitrators shall be binding upon Landlord and Tenant.

 4.5 If either Landlord or Tenant fails to appoint an arbitrator within the time
period specified in Section 4.1 hereinabove, the arbitrator appointed by one of them shall reach a decision, notify Landlord and Tenant thereof, and such arbitrator’s decision shall be binding upon Landlord and Tenant. 

4.6 If the two (2) arbitrators fail to agree upon and appoint a third arbitrator, within the time period provided in
Section 4.2 above, then the parties shall mutually select the third arbitrator. If Landlord and Tenant are unable to agree upon the third arbitrator within ten (10) days after the fifteen (15) day period described in Section 4.2
above, then either party may, upon at least five (5) days’ prior written notice to the other party, request the Presiding Judge of the San Diego County Superior Court, acting in his private and nonjudicial capacity, to appoint the third
arbitrator. Following the appointment of the third arbitrator, the panel of arbitrators shall within thirty (30) days thereafter reach a decision as to whether Landlord’s or Tenant’s submitted Fair Market Rental Rate shall be used and
shall notify Landlord and Tenant thereof.
