 THIS INDENTURE OF LEASE (this “Lease”) is hereby made and entered into on the
Execution Date by and between Landlord and Tenant. 
 Each reference in this Lease to any of the terms and titles contained in any Exhibit
attached to this Lease shall be deemed and construed to incorporate the data stated under that term or title in such Exhibit. All capitalized terms not otherwise defined herein shall have the meanings ascribed to them as set forth in the Lease
Summary Sheet which is attached hereto and incorporated herein by reference. 
 1. LEASE GRANT; TERM; APPURTENANT RIGHTS; EXCLUSIONS 

1.1 Lease Grant. Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the Premises upon and subject to terms and
conditions of this Lease, for a term of years commencing on the Term Commencement Date and, unless earlier terminated pursuant to the terms hereof, ending on the Expiration Date (the “Initial Term”; the Initial Term and any duly
exercised Extension Terms are hereinafter collectively referred to as the “Term”). 
 1.2 Extension Term. 

(a) Provided that the following conditions, which may be waived by Landlord in its sole discretion, are satisfied (i) Tenant, an
Affiliated Entity (hereinafter defined) and/or a Successor (hereinafter defined) is/are then occupying one hundred percent (100%) of the Premises; and (ii) no Event of Default has occurred and is continuing (1) as of the date of the
Extension Notice (hereinafter defined), and (2) at the commencement of the Extension Term (hereinafter defined), Tenant shall have the option to extend the Term for one (1) additional term of five (5) years (the “Extension
Term”), commencing as of the expiration of the Initial Term. Tenant must exercise such option to extend, if at all, by giving Landlord written notice (the “Extension Notice”) on or before the date that is twelve
(12) months prior to the expiration of the then-current term of this Lease, time being of the essence. Upon the timely giving of such notice, the Term shall be deemed extended upon all of the terms and conditions of this Lease, except
that Base Rent during the Extension Term shall be calculated in accordance with this Section 1.2, Landlord shall have no obligation to construct or renovate the Premises and Tenant shall have no further right to extend the Term. If Tenant fails
to give timely notice, as aforesaid, 
 Tenant shall have no further right to extend the Term. Notwithstanding the fact that Tenant’s proper and timely
exercise of such option to extend the Term shall be self executing, the parties shall promptly execute a lease amendment reflecting such Extension Term after Tenant exercises such option. The execution of such lease amendment shall not be deemed to
waive any of the conditions to Tenant’s exercise of its rights under this Section 1.2. 
 (b) The Base Rent during the Extension
Term (the “Extension Term Base Rent”) shall be determined in accordance with the process described hereafter. Extension Term Base Rent shall be the fair market rental value of the Premises then demised to Tenant as of the
commencement of the Extension Term as determined in accordance with the process described below, for renewals of office space in the East Cambridge area of equivalent quality, size, utility, location, and proximity to public transit, with the length
of the Extension Term, the credit 

  
 PAGE 1 

 
standing of Tenant and all other relevant factors to be taken into account. Within thirty (30) days after receipt of the Extension Notice, Landlord shall deliver to Tenant written notice
(“Landlord’s Quotation”) of its determination of the Extension Term Base Rent for the Extension Term. Within thirty (30) days after Tenant’s receipt of Landlord’s Quotation (the “Negotiation
Period”), Landlord and the Tenant shall negotiate in good faith to reach agreement on the Extension Term Base Rent. Subject to Section 1.2(c) below, if Landlord and Tenant have not so agreed and executed a written instrument evidencing
such agreement within the Negotiation Period, then Landlord’s determination of the Extension Term Base Rent as set forth in Landlord’s Quotation shall be binding on Tenant. For the avoidance of doubt, Landlord and Tenant agree that neither
party shall be obligated to agree on the Extension Term Base Rent during the Negotiation Period. 
 (c) If and only if Tenant notifies
Landlord in writing during the Negotiation Period that it rejects Landlord’s determination of the Extension Term Base Rent and desires to submit the matter to arbitration (“Tenant’s Rejection Notice”), then the Extension
Term Base Rent shall be determined in accordance with the procedure set forth in this Section 1.2(c). In such event, within ten (10) days after receipt by Landlord of Tenant’s Rejection Notice indicating Tenant’s desire to submit
the determination of the Extension Term Base Rent to arbitration, Tenant and Landlord shall each notify the other, in writing, of their respective selections of an appraiser (respectively, “Landlord’s Appraiser” and
“Tenant’s Appraiser”). Landlord’s Appraiser and Tenant’s Appraiser shall then jointly select a third appraiser (the “Third Appraiser”) within ten (10) days of their appointment. All of the
appraisers selected shall be individuals with at least five (5) consecutive years’ commercial appraisal experience in the area in which the Premises are located, shall be members of the Appraisal Institute (“MAI”), and, in
the case of the Third Appraiser, shall not have acted in any capacity for either Landlord or Tenant within five (5) years of his or her selection. The three appraisers shall determine the Extension Term Base Rent in accordance with the
requirements and criteria set forth in Section 1.2(b) above, employing the method commonly known as Baseball Arbitration, whereby Landlord’s Appraiser and Tenant’s Appraiser each sets forth its determination of the Extension Term Base
Rent as defined above, and the Third Appraiser must select one or the other (it being understood that the Third Appraiser shall be expressly prohibited from selecting a compromise figure). Landlord’s Appraiser and Tenant’s Appraiser shall
deliver their determinations of the Extension Term Base Rent to the Third Appraiser within five (5) days of the appointment of the Third Appraiser and the Third Appraiser shall render his or her decision within ten (10) days after receipt
of both of the other two determinations of the Extension Term Base Rent. The Third Appraiser’s decision shall be binding on both Landlord and Tenant. Each party shall bear the cost of its own appraiser. Landlord and Tenant shall bear the
expense of the Third Appraiser equally. 
 1.3 Appurtenant Rights. 

(a) Common Areas. Subject to the terms of this Lease and the Building Rules and Regulations (hereinafter defined), Tenant shall have, as
appurtenant to the Premises, rights to use in common with others entitled thereto the following areas (such areas are hereinafter referred to as the “Common Areas”): (i) the common freight elevators, loading docks and hallways
of the Building serving the Premises, (ii) common walkways and driveways necessary for access to the Building, (iii) the common lobbies, corridors, stairways, toilets and elevators of 

  
 PAGE 2 

 
the Building, (iv) the common electrical room and “demarc” closet located on the sixteenth (16th) floor of the Building
(solely for the purpose of purposes of installing electrical and telecommunications equipment), (v) the pipes, ducts, shafts (to the extent available), conduits, wires and appurtenant meters and equipment serving the Premises in common with
others, and (vi) other areas and facilities designated by Landlord from time to time for the common use of tenants of the Building; and no other appurtenant rights or easements. 

(b) Parking. During the Term, Landlord shall, subject to the terms hereof, make available eighteen (18) parking spaces (i.e., 0.9
parking spaces per 1,000 square feet of rentable square feet of the Premises of 19,805 rentable square feet) for Tenant’s use in the parking garage attached to the Buildings. The number of parking spaces in the garage used by Tenant, as
modified pursuant to this Lease or as otherwise permitted by Landlord, are hereinafter referred to as the “Parking Spaces.” Subject to Landlord’s right to reserve parking spaces for other tenants in the Building, use of
unreserved Parking Spaces shall be on an unassigned, first-come, first-served basis. Tenant shall pay for such Parking Spaces at the prevailing monthly rates from time to time charged by the operator or operators of the Garage, whether or not such
operator is an affiliate of Landlord. Such monthly parking charges for Parking Spaces shall constitute Additional Rent and shall be payable monthly as directed by Landlord upon billing therefor by Landlord or such operator. As of the Execution Date
of this Lease, the current parking charge is $280.00 per space per month. Tenant acknowledges that said monthly charges to be paid under this Section 1.3(b) are for the use by Tenant of the Parking Spaces referred to herein, and not for any
other service. 
 Tenant shall have no right to hypothecate or encumber the Parking Spaces, and shall not sublet, assign, or otherwise
transfer the Parking Spaces other than to employees of Tenant occupying the Premises or to a Successor (hereinafter defined), an Affiliated Entity (hereinafter defined) or a transferee pursuant to an approved Transfer under Section 13 of this
Lease. Subject to Landlord’s right to reserve parking for other tenants of the Building, said Parking Spaces will be on an unassigned, non-reserved basis, and shall be subject to such reasonable rules and regulations as may be in effect for the
use of the parking areas from time to time. Reserved and handicap parking spaces must be honored. 
 1.4 Tenant’s Access. From
and after the Term Commencement Date and until the end of the Term, Tenant shall have access to the Premises twenty-four (24) hours a day, seven (7) days a week, subject to Legal Requirements, the Building Rules and Regulations and the
terms of this Lease. The parties acknowledge that (i) security is provided at a manned security station in the lobby and is staffed twenty-four (24) hours a day, seven (7) days a week and (ii) the Building currently has an
electronic card access security system to allow Tenant and its authorized employees access to the Building during non-business hours. Landlord shall, upon written request from Tenant and without additional charge to Tenant, provide up to 150
electronic access cards to Tenant. Tenant shall comply with all reasonable security measures from time to time established by Landlord for the Building. 

1.5 No recording; Notice of Lease. Tenant shall not record this lease or any portion hereof, a memorandum of this Lease and/or a notice
of this Lease. Neither party shall record this Lease, but each of the parties hereto agrees to join in the execution, in recordable form, of a statutory notice of lease and/or written declaration in which shall be stated the Term

  
 PAGE 3 

 
Commencement Date, the Rent Commencement Date, the number and length of the Extension Term(s) and the Expiration Date, which notice of lease may be recorded by Tenant with the Middlesex South
Registry of Deeds and/or filed with the Middlesex South Registry District of the Land Court, as appropriate (alternatively and collectively, the “Registry”) at Tenant’s sole cost and expense. If a notice of lease was previously
recorded with the Registry, upon the expiration or earlier termination of this Lease, Landlord shall deliver to Tenant a notice of termination of lease and Tenant shall promptly execute, acknowledge, and deliver the same (together with any other
instrument(s) that may be necessary in order to record and/or file same with the Registry) to Landlord for Landlord’s execution and recordation with the Registry, which obligation shall survive the expiration or earlier termination of the
Lease. 
 1.6 Exclusions. The following are expressly excluded from the Premises and reserved to Landlord: the exterior glass and
curtain wall, all the perimeter walls of the Premises (except the inner surfaces thereof), the Common Areas, and any space in or adjacent to the Premises used for shafts, stacks, pipes, conduits, wires and appurtenant fixtures, fan rooms, ducts,
electric or other utilities, sinks or other Building facilities, and the use of all of the foregoing, except as expressly permitted pursuant to Section 1.3 above. 

1.7 Furniture. Landlord shall cause the Current Tenant, as hereinafter defined, to convey its interest in substantially all of those
items of furniture described in the Bill of Sale attached hereto as Exhibit 6 within a reasonable period of time after the Execution Date. 
 2.
RIGHTS RESERVED TO LANDLORD

 PAGE 4 

 (b) Landlord and Tenant each hereby acknowledges and agrees that, in connection with any Future

recordable form making this Lease subject and subordinate to the Master Deed and other documents evidencing the Condominium (collectively, the “Condo Documents”) provided that such Condo Documents continue to provide Tenant with all
of the rights and obligations contained in this Lease (e.g. the appurtenant right to use all Common Areas) and the Condo Documents comply with the provisions of this Section 2.2; (iii) Landlord shall have the right to enter into, and
subject the Property to the terms and conditions of, a reciprocal easement agreement with any one or more of the neighboring property owners in order to create a commercial campus-like setting (“REA”) provided that such REA
continues to provide Tenant with all of the rights and obligations contained in this Lease as of the Execution Date (e.g. the appurtenant right to use all Common Areas) and the REA complies with the provisions of this Section 2.2;
(iv) Landlord shall submit to Tenant for Tenant’s approval drafts of the Condo Documents and the REA (and any amendments thereto) prior to their execution; (v) Tenant shall have the right to notify Landlord within twenty
(20) days after receipt of the draft Condo Documents and/or REA (or any amendments thereto) of Tenant’s objection(s) thereto, but only to the extent such draft(s) (A) materially adversely affect Tenant’s use of, or access to, the
Premises, (B) materially adversely affect the operation of Tenant’s business from the Premises in accordance with the terms of this Lease, or Tenant’s rights under and pursuant to the terms of this Lease, including without limitation
Tenant’s rights with respect to the Common Areas, and/or (C) result in any increase in Tenant’s payment or other obligations under this Lease in more than a de minimis manner; (vi) upon Landlord’s request in connection with
the recording of the REA, Tenant shall execute a commercially reasonable instrument in recordable form making this Lease subject and subordinate to the REA; (vii) Landlord shall have the right to subdivide the Property so long as Tenant
continues to have all of the rights and obligations contained in this Lease (e.g. the appurtenant right to use all Common Areas); and (vii) Tenant shall execute such reasonable documents (which may be in recordable form) evidencing the
foregoing promptly upon Landlord’s request. 
 (c) In case any excavation shall be made for building or improvements or for any other
purpose upon the land adjacent to or near the Premises, Tenant will afford without charge to Landlord, or the person or persons, firms or corporations causing or making such excavation, license to enter upon the Premises for the purpose of doing
such work as Landlord or such person or persons, firms or corporation shall deem to be necessary to preserve the walls or structures of the building from injury, and to protect the building by proper securing of foundations. 

2.3 Name and Address of Building. Landlord reserves the right at any time and from time to time to change the name or address of the
Building and/or the Property, provided Landlord gives Tenant at least three (3) months’ prior written notice thereof. 
 2.4
Landlord’s Access. Subject to the terms hereof, Tenant shall (a) upon as much advance notice as is practical under the circumstances, and in any event at least twenty-four (24) hours’ prior written notice (except that no
notice shall be required in emergency situations), permit Landlord and any holder of a Mortgage (hereinafter defined) (each such holder, a 

  
 PAGE 5 

 
“Mortgagee”), and the agents, representatives, employees and contractors of each of them, to have reasonable access to the Premises at all reasonable hours for the purposes of
inspection, making repairs, replacements or improvements in or to the Premises or the Building or equipment therein (including, without limitation, sanitary, electrical, heating, air conditioning or other systems), complying with all applicable
laws, ordinances, rules, regulations, statutes, by-laws, court decisions and orders and requirements of all public authorities (collectively, “Legal Requirements”), or exercising any right reserved to Landlord under this Lease
(including without limitation the right to take upon or through, or to keep and store within the Premises all necessary materials, tools and equipment); (b) permit Landlord and its agents and employees, at reasonable times, upon reasonable
advance written notice, to show the Premises during Normal Business Hours (as defined in Section 9.6 below) to any prospective Mortgagee or purchaser of the Building and/or the Property or of the interest of Landlord therein, and, during the
last twelve (12) months of the Term, prospective tenants; and (c) upon reasonable prior written notice from Landlord, permit Landlord and its agents, at Landlord’s sole cost and expense, to perform environmental audits, environmental
site investigations and environmental site assessments (“Site Assessments”) in, on, under and at the Premises and the Land, it being understood that Landlord shall repair any damage arising as a result of the Site Assessments, and
such Site Assessments may include both above and below the ground testing and such other tests as may be necessary or appropriate to conduct the Site Assessments. In addition, to the extent that it is necessary to enter the Premises in order to
access any area that serves any portion of the Building outside the Premises, then Tenant shall, upon as much advance notice as is practical under the circumstances, and in any event at least twenty-four (24) hours’ prior written notice
(except that no notice shall be required in emergency situations), permit contractors engaged by other occupants of the Building to pass through the Premises in order to access such areas but only if accompanied by a representative of Landlord. 

2.5 Pipes, Ducts and Conduits. Tenant shall permit Landlord to erect, use, maintain and relocate pipes, ducts and conduits in and
through the Premises, provided the same do not materially reduce the floor area or materially adversely affect the appearance thereof and provided that such relocated pipes, ducts and conduits shall be located, so far as practicable, in the central
core of the Building, above ceiling surfaces, below floor surfaces or within perimeter walls of the Premises. 
 2.6 Minimize
Interference. Except in the event of an emergency, Landlord shall use commercially reasonable efforts to minimize any interference with Tenant’s business operations and use and occupancy of the Premises in connection with the exercise any
of the foregoing rights under this Section 2, including consulting with Tenant as to the manner and timing of such work. 
 3. CONDITION OF
PREMISES; CONSTRUCTION. 
 3.1 Condition of Premises. 

(a) Except as set forth in this Section 3.1, Tenant acknowledges and agrees that Tenant is leasing the Premises in their “AS
IS,” “WHERE IS” condition and with all faults on the Execution Date, without representations or warranties, express or implied, in fact or by law, of any kind, and without recourse to Landlord. Notwithstanding the
foregoing, as of the 

  
 PAGE 6 

 
Term Commencement Date: (i) the Premises shall be delivered to Tenant free and clear of all tenants and occupants and free of all property and debris, except for that furniture described in
the Bill of Sale attached as Exhibit 6, and otherwise in broom clean condition (Tenant hereby acknowledging that the Premises are currently leased to another tenant (“Current Tenant”) pursuant to a lease, the term of which
expires as of August 31, 2016), (ii) the roof of the Building shall be watertight, and (iii) the Building systems serving the Premises, including, without limitation, the base building HVAC, electrical, life safety and plumbing
systems serving the Premises shall be in good working order (collectively “Commencement Date Conditions”). Tenant shall be conclusively be deemed to have agreed that the Commencement Date Conditions have been satisfied unless,
within seven (7) days after Landlord gives written notice to Tenant that the Commencement Date Conditions have been satisfied, Tenant gives written notice to Landlord setting forth with specificity Tenant’s objections to such notice.
Tenant shall not be required to pay for such costs (if any) as Landlord is required to incur in order to satisfy the Commencement Date Conditions. Nothing in this Section 3.1 shall relieve Landlord of its maintenance and repair obligations as
set forth in Section 10.2 of the Lease. Subject to Section 3.1(b) below, Landlord’s failure to cause the Term Commencement Date to occur by September 1, 2016 (the “Estimated Commencement Date”) shall in no way
affect the validity of this Lease or the obligations of Tenant hereunder, and Tenant shall not have any claim against Landlord by reason thereof. 

(b) Notwithstanding the foregoing, in the event that Landlord shall be unable to cause the Term Commencement Date to occur on or before the
Estimated Commencement Date due to the failure of the Current Tenant to vacate the Premises on or before the Estimated Commencement Date, then (i) Landlord shall have no liability to Tenant therefor, (ii) Tenant shall not have the right to
terminate the Lease, (iii) Tenant shall accept delivery of the Premises when delivered by Landlord with the Commencement Date Conditions satisfied, (iv) Landlord shall promptly deliver to the Current Tenant a written demand to immediately
vacate the Premises, (v) Landlord shall use diligent efforts to recover possession of the Premises as soon as possible from the Current Tenant, including, without limitation, commencing and diligently prosecuting summary process proceedings
against the Current Tenant and (vi) Landlord shall use reasonable efforts to obtain any Holdover Premium (as hereinafter defined) payable by the Current Tenant to Landlord under the Current Tenant’s existing lease as a result of such
holdover. For the purposes hereof, the “Holdover Premium” shall be defined as the amount by which the occupancy charges and other amounts payable by the Current Tenant as the result of its hold over in the Premises after the
Estimated Commencement Date exceed the amount which the Current Tenant would have paid to Landlord with respect to such hold over period had the rental rate payable by the Current Tenant during the hold over period been the same as the rental rate
payable by the Current Tenant with respect to the Premises immediately prior to the expiration date of the Current Tenant’s existing lease. Landlord shall pay to Tenant any Holdover Premium which it collects from the Current Tenant, net of the
reasonable costs incurred by Landlord (including, without limitation, reasonable attorneys’ fees) in obtaining the Holdover Premium and/or recovering possession of the Premises from the Current Tenant. 

3.2 Initial Alterations. Tenant, at Tenant’s sole cost and expense, but subject to Tenant’s right to receive the Allowance,
shall perform the work (the “Initial Alterations”) more particularly described in Exhibit 3 attached hereto. The Initial Alterations shall be performed in accordance with the provisions of Article 11 hereof. 

  
 PAGE 7 

 4. USE OF PREMISES 

4.1 Permitted Uses. During the Term, Tenant shall use the Premises only for the Permitted Uses and for no other purposes. Service and
utility areas (whether or not a part of the Premises) shall be used only for the particular purpose for which they are designed. Tenant shall keep the Premises equipped with appropriate safety appliances to the extent required by Legal Requirements,
as hereinafter defined, or insurance requirements. 
 4.2 Prohibited Uses. 

(a) Notwithstanding any other provision of this Lease, Tenant shall not use the Premises or the Building, or any part thereof, or suffer or
permit the use or occupancy of the Premises or the Building or any part thereof by any of the Tenant Parties (i) in a manner which would violate any of the covenants, agreements, terms, provisions and conditions of this Lease or otherwise
applicable to or binding upon the Premises of which Tenant has been provided notice; (ii) for any unlawful purposes or in any unlawful manner; (iii) which, in the reasonable judgment of Landlord (taking into account the use of the Building
as a combination laboratory, research and development and office building and the Permitted Uses) shall (a) impair the appearance or reputation of the Building; (b) impair, interfere with or otherwise diminish the quality of any of the
Building services or the proper and economic heating, cleaning, ventilating, air conditioning or other servicing of the Building or Premises, or the use or occupancy of any of the Common Areas; (c) occasion discomfort, inconvenience or
annoyance in any material respect (and Tenant shall not install or use any electrical or other equipment of any kind which, in the reasonable judgment of Landlord, will cause any such impairment, interference, discomfort, inconvenience, annoyance or
injury), or cause any injury or damage to any occupants of the Premises or other tenants or occupants of the Building or their property; or (d) cause harmful air emissions, laboratory odors or noises or any unusual or other objectionable odors,
noises or emissions to emanate from the Premises; (iv) in a manner which is inconsistent with the operation and/or maintenance of the Building as a first-class combination office, research, development and laboratory facility; (v) for any
fermentation processes whatsoever; or (vi) in a manner which shall increase such insurance premiums on the Building or on property located therein over that applicable when Tenant first took occupancy of the Premises hereunder. 

(b) With respect to the use and occupancy of the Premises and the Common Areas, Tenant will not: (i) place or maintain any signage (except
as set forth in Section 12.2 below), trash, refuse or other articles in any vestibule or entry of the Premises, on the footwalks or corridors adjacent thereto or elsewhere on the exterior of the Premises, nor obstruct any driveway, corridor,
footwalk, parking area, mall or any other Common Areas; (ii) permit undue accumulations of or burn garbage, trash, rubbish or other refuse within or without the Premises; (iii) permit the parking of vehicles so as to interfere with the use
of any driveway, corridor, footwalk, parking area, or other Common Areas; (iv) receive or ship articles of any kind outside of those areas reasonably designated by Landlord; (v) conduct or permit to be conducted any auction, going out of
business sale, bankruptcy sale (unless directed by court order), or other similar type sale in or connected with the Premises; (vi) use the name of Landlord, or any of Landlord’s affiliates in any publicity, promotion, trailer, press
release, advertising, printed, or display materials without Landlord’s prior written consent; or (vii) except in connection with Alterations (hereinafter defined) approved by Landlord, cause or permit any hole to be drilled or made in any
part of the Building. 

  
 PAGE 8 

 4.3 Parking and Traffic Demand Management Plan. Tenant acknowledges that the Property may
become subject to a traffic mitigation and/or management plan (as the same may be amended from time to time, the “PTDM”). So long as Landlord provides a copy thereof to Tenant, Tenant agrees not to violate the terms of the
PTDM applicable to tenants of the Building. To the extent required by the PTDM, Tenant shall, at Tenant’s sole expense, (a) participate in any designated transportation management association, (b), allow employees at the Premises to
set-aside pre-tax funds as allowable under the Commuter Choice provision of the Federal tax code, and (c) reasonably cooperate with Landlord (i) in connection with Landlord’s reporting obligations under the PTDM, and (ii) to
encourage employees to avoid vehicle trips at peak commuting hours and to seek alternate modes of transportation. The costs incurred by Landlord in connection with compliance with the PTDM shall be included in Expenses. 

5. RENT; ADDITIONAL RENT 
 5.1 Base
Rent. During the Term, Tenant shall pay to Landlord Base Rent in equal monthly installments, in advance and without demand on the first day of each month for and with respect to such month. Unless otherwise expressly provided herein, the payment
of Base Rent, Additional Rent, as hereinafter defined, and other charges reserved and covenanted to be paid under this Lease with respect to the Premises (collectively, “Rent”) shall commence on the Rent Commencement Date, and shall
be prorated for any partial months. Additional Rent” means all sums (exclusive of Base Rent) that Tenant is required to pay Landlord under this Lease. Rent shall be payable to Landlord or, if Landlord shall so direct in writing, to
Landlord’s agent or nominee, in lawful money of the United States which shall be legal tender for payment of all debts and dues, public and private, at the time of payment. 

5.2 Additional Rent. “Additional Rent” means all sums (exclusive of Base Rent) that Tenant is required to pay Landlord
under this Lease, including, without limitation, Expense Excess, Tax Excess, and Common Area Expense Excess, as such terms are defined in Exhibit 7. 

5.3 Late Payments. 
 (a)
Any payment of Rent due hereunder not paid when due shall bear interest for each month or fraction thereof from the due date until paid in full at the annual rate of twelve percent (12%), or at any applicable lesser maximum legally permissible rate
for debts of this nature (the “Default Rate”). 
 (b) Additionally, if Tenant fails to make any payment within five
(5) days after the due date therefor, Landlord may charge Tenant a fee (each, a “Late Fee”), which shall constitute liquidated damages, equal to One Thousand and NO/100 Dollars ($1,000.00) for each such late payment.
Notwithstanding the foregoing, Tenant shall not be required to pay a Late Fee with respect to the first time, if any, in any calendar year that Tenant fails to make any payment when due. 

  
 PAGE 9 

 (c) For each Tenant payment check to Landlord that is returned by a bank for any reason, Tenant
shall pay a returned check charge equal to the amount as shall be customarily charged by Landlord’s bank at the time. 
 (d) Money paid
by Tenant to Landlord shall be applied to Tenant’s account in the following order: first, to any unpaid Additional Rent, including without limitation late charges, returned check charges, legal fees and/or court costs chargeable to Tenant
hereunder; and then to unpaid Base Rent. 
 (e) The parties agree that the late charge referenced in Section 5.4(b) represents a fair
and reasonable estimate of the costs that Landlord will incur by reason of any late payment by Tenant, and the payment of late charges and interest are distinct and separate in that the payment of interest is to compensate Landlord for the use of
Landlord’s money by Tenant, while the payment of late charges is to compensate Landlord for Landlord’s processing, administrative and other costs incurred by Landlord as a result of Tenant’s delinquent payments. Acceptance of a late
charge or interest shall not constitute a waiver of Tenant’s default with respect to the overdue amount or prevent Landlord from exercising any of the other rights and remedies available to Landlord under this Lease or at law or in equity now
or hereafter in effect. 
 (f) If Tenant during any six (6) month period shall be more than five (5) days delinquent in the payment
of any installment of Rent on three (3) or more occasions, then, notwithstanding anything herein to the contrary, Landlord may, by written notice to Tenant, elect to require Tenant to pay all Base Rent and Additional Rent on account of Expenses
and Taxes quarterly in advance. Such right shall be in addition to and not in lieu of any other right or remedy available to Landlord hereunder or at law on account of Tenant’s default hereunder. 

5.4 No Offset; Independent Covenants; Waiver. Rent shall be paid without notice or demand, and without setoff, counterclaim, defense,
abatement, suspension, deferment, reduction or deduction, except as expressly provided herein. EXCEPT AS EXPRESSLY SET FORTH IN SECTION 5.1 (WITH RESPECT TO THE RENT COMMENCEMENT DATE), SECTION 9.7 (WITH RESPECT TO SERVICE INTERRUPTIONS) OR
SECTION 15.1 (WITH RESPECT TO A CASUALTY OR TAKING), TENANT WAIVES ALL RIGHTS (I) TO ANY ABATEMENT, SUSPENSION, DEFERMENT, REDUCTION OR DEDUCTION OF OR FROM RENT, AND (II) TO QUIT, TERMINATE OR SURRENDER THIS LEASE OR THE PREMISES OR ANY PART
THEREOF, EXCEPT AS EXPRESSLY PROVIDED HEREIN. TENANT HEREBY ACKNOWLEDGES AND AGREES THAT THE OBLIGATIONS OF TENANT HEREUNDER SHALL BE SEPARATE AND INDEPENDENT COVENANTS AND AGREEMENTS, THAT RENT SHALL CONTINUE TO BE PAYABLE IN ALL EVENTS AND THAT
THE OBLIGATIONS OF TENANT HEREUNDER SHALL CONTINUE UNAFFECTED, UNLESS THE REQUIREMENT TO PAY OR PERFORM THE SAME SHALL HAVE BEEN TERMINATED OR ABATED PURSUANT TO AN EXPRESS PROVISION OF THIS LEASE. LANDLORD AND TENANT EACH ACKNOWLEDGES AND AGREES
THAT THE INDEPENDENT NATURE OF THE OBLIGATIONS OF TENANT HEREUNDER REPRESENTS FAIR, REASONABLE, AND ACCEPTED COMMERCIAL PRACTICE WITH RESPECT TO THE TYPE OF PROPERTY SUBJECT TO THIS LEASE, AND THAT THIS AGREEMENT IS THE PRODUCT OF

  
 PAGE 10 

 
FREE AND INFORMED NEGOTIATION DURING WHICH BOTH LANDLORD AND TENANT WERE REPRESENTED BY COUNSEL SKILLED IN NEGOTIATING AND DRAFTING COMMERCIAL LEASES IN MASSACHUSETTS, AND THAT THE
ACKNOWLEDGEMENTS AND AGREEMENTS CONTAINED HEREIN ARE MADE WITH FULL KNOWLEDGE OF THE HOLDING IN WESSON V. LEONE ENTERPRISES, INC., 437 MASS. 708 (2002). SUCH ACKNOWLEDGEMENTS, AGREEMENTS AND WAIVERS BY TENANT ARE A MATERIAL INDUCEMENT TO
LANDLORD ENTERING INTO THIS LEASE. 
 5.5 Survival. Any payment obligations under this Section 5 which shall not have been
paid at the expiration or earlier termination of the Term shall survive such expiration or earlier termination and shall be paid when and as the amount of same shall be determined and be due. 

6. INTENTIONALLY OMITTED. 
 7. LETTER OF CREDIT

 7.1 Amount. Contemporaneously with the execution of this Lease, Tenant shall deliver to Landlord either (i) cash in the
amount specified in the Lease Summary Sheet (the “Cash Security Deposit”), which shall be held by Landlord in accordance with Section 7.5 below, or (ii) an irrevocable letter of credit (the “Letter of
Credit”) that shall (a) be in the initial amount of $524,832.52; (b) be issued on the form attached hereto as Exhibit 5; (c) name Landlord as its beneficiary; and (d) be drawn on an FDIC insured financial
institution reasonably satisfactory to Landlord that satisfies both the Minimum Rating Agency Threshold and the Minimum Capital Threshold (as those terms are defined below). The “Minimum Rating Agency Threshold” shall mean that the
issuing bank has outstanding unsecured, uninsured and unguaranteed senior long-term indebtedness that is then rated (without regard to qualification of such rating by symbols such as “+” or “-” or numerical notation)
“Baa” or better by Moody’s Investors Service, Inc. and/or “BBB” or better by Standard & Poor’s Rating Services, or a comparable rating by a comparable national rating agency designated by Landlord in its
discretion. The “Minimum Capital Threshold” shall mean that the issuing bank has combined capital, surplus and undivided profits of not less than $10,000,000,000. As of the Execution Date, Landlord approves Silicon Valley Bank as
the issuer of the Letter of Credit. The Letter of Credit (and any renewals or replacements thereof) shall be for a term of not less than one (1) year. If the issuer of the Letter of Credit gives written notice of its election not to renew such
Letter of Credit for any additional period, Tenant shall be required to deliver a substitute Letter of Credit satisfying the conditions hereof at least thirty (30) days prior to the expiration of the term of such Letter of Credit. If the issuer
of the Letter of Credit fails to satisfy either or both of the Minimum Rating Agency Threshold or the Minimum Capital Threshold, Tenant shall be required to deliver a substitute letter of credit from another issuer reasonably satisfactory to the
Landlord and that satisfies both the Minimum Rating Agency Threshold and the Minimum Capital Threshold not later than ten (10) business days after Landlord notifies Tenant of such failure. Tenant agrees that it shall from time to time, as
necessary, whether as a result of a draw on the Letter of Credit by Landlord pursuant to the terms hereof or as a result of the expiration of the Letter of Credit then in effect, renew or replace the original and any subsequent Letter of Credit so
that a Letter of Credit, in the amount required hereunder, is in effect until a date which 

  
 PAGE 11 

 
is at least sixty (60) days after the Expiration Date. If Tenant fails to furnish such renewal or replacement at least thirty (30) days prior to the stated expiration date of the Letter
of Credit then held by Landlord, Landlord may draw upon such Letter of Credit and hold the proceeds thereof (and such proceeds need not be segregated) as a Security Deposit pursuant to the terms of this Article 7. Any renewal or replacement of the
original or any subsequent Letter of Credit shall meet the requirements for the original Letter of Credit as set forth above, except that such replacement or renewal shall be issued by a national bank reasonably satisfactory to Landlord at the time
of the issuance thereof. 
 7.2 Application of Proceeds of Letter of Credit. Upon an Event of Default, or if any proceeding shall be
instituted by or against Tenant pursuant to any of the provisions of any Act of Congress or State law relating to bankruptcy, reorganizations, arrangements, compositions or other relief from creditors (and, in the case of any proceeding instituted
against it, if Tenant shall fail to have such proceedings dismissed within thirty (30) days) or if Tenant is adjudged bankrupt or insolvent as a result of any such proceeding, Landlord at its sole option may draw down all or a part of the
Letter of Credit. The balance of any Letter of Credit cash proceeds shall be held in accordance with Section 7.5 below. Should the entire Letter of Credit, or any portion thereof, be drawn down by Landlord, Tenant shall, upon the written demand
of Landlord, deliver a replacement Letter of Credit in the amount drawn, and Tenant’s failure to do so within ten (10) business days after receipt of such written demand shall constitute an additional Event of Default hereunder. The
application of all or any part of the cash proceeds of the Letter of Credit to any obligation or default of Tenant under this Lease shall not deprive Landlord of any other rights or remedies Landlord may have nor shall such application by Landlord
constitute a waiver by Landlord. 
 7.3 Transfer of Letter of Credit. In the event that Landlord transfers its interest in the
Premises, Tenant shall upon written notice from and at no cost to Landlord, deliver to Landlord an amendment to the Letter of Credit or a replacement Letter of Credit naming Landlord’s successor as the beneficiary thereof. If Tenant fails to
deliver such amendment or replacement within ten (10) business days after written notice from Landlord, Landlord shall have the right to draw down the entire amount of the Letter of Credit and hold the proceeds thereof in accordance with
Section 7.5 below. 
 7.4 Cash Proceeds of Letter of Credit. Landlord shall hold the Cash Security Deposit and/or the balance of
proceeds remaining after a draw on the Letter of Credit (each hereinafter referred to as the “Security Deposit”) as security for Tenant’s performance of all its Lease obligations. After an Event of Default, Landlord may apply
the Security Deposit, or any part thereof, to Landlord’s damages without prejudice to any other Landlord remedy. Landlord has no obligation to pay interest on the Security Deposit and may co-mingle the Security Deposit with Landlord’s
funds. If Landlord conveys its interest under this Lease, the Security Deposit, or any part not applied previously, may be turned over to the grantee in which case Tenant shall look solely to the grantee for the proper application and return of the
Security Deposit. 
 7.5 Return of Security Deposit or Letter of Credit. Should Tenant comply with all of such terms, covenants and
conditions and promptly pay all sums payable by Tenant to Landlord hereunder, the Security Deposit and/or Letter of Credit or the remaining proceeds therefrom, as applicable, shall be returned to Tenant within sixty (60) days after the end of
the Term, less any portion thereof which may have been utilized by Landlord to cure any Event of Default or applied to any actual damage suffered by Landlord.

9. UTILITIES, LANDLORD’S SERVICES 

9.1 Electricity. Landlord and Tenant acknowledge that the Premises are separately metered for electricity (i.e., for lights, plugs, and
HVAC heat pump units). Tenant shall pay the full amount of the cost of electricity consumed in the Premises, as measured by such meter on or before the due date therefor directly to the supplier thereof. 

9.2 Water. Landlord shall furnish, or cause to be furnished, water to the Premises in such manner as is reasonably deemed by Landlord to
be adequate for Tenant’s use and occupancy of the Premises, and the cost thereof shall be included in Expenses. If Landlord reasonably believes that Tenant is using or consuming more water than is customarily consumed by typical office tenants,
Landlord may (i) assess a reasonable charge for the additional water so used or consumed by Tenant or (ii) install a water meter and thereby measure Tenant’s water consumption for all purposes. In the latter event, Landlord may elect,
at Tenant’s sole cost and expense, to furnish and install in a location selected by Landlord in or near the Premises any necessary metering or submetering equipment reasonably acceptable to Landlord and the supplier thereof to be used to
measure water furnished to the Premises and any equipment exclusively serving the same. If applicable, Tenant shall, at Tenant’s sole cost and expense, maintain and keep in good order, condition and repair the metering or submetering equipment
used to measure water furnished to the Premises and any equipment exclusively serving the same. Tenant shall pay the full amount of the cost of water consumed in the Premises, as measured by such meter or submeter on or before the due date therefor
either to Landlord or directly to the supplier thereof, at Landlord’s election.  
 9.3 Gas. Landlord shall furnish, or
cause to be furnished, gas to the Premises in such manner as is reasonably deemed by Landlord to be adequate for Tenant’s use and occupancy of the Premises, and the cost thereof shall be included in Expenses. If Landlord reasonably believes
that Tenant is using or consuming more gas than is customarily consumed by typical office tenants, Landlord may (i) assess a reasonable charge for the additional gas so used or consumed by Tenant or (ii) install a gas meter and thereby
measure Tenant’s gas consumption for all purposes. In the latter event, Landlord may elect, at Tenant’s sole cost and expense, to furnish and install in a location selected by Landlord in or near the Premises any necessary metering or
submetering equipment reasonably acceptable to Landlord and the supplier thereof to be used to measure gas furnished to the Premises and any equipment exclusively serving the same. Tenant shall pay the full amount of the cost of gas consumed in the
Premises, as measured by such meter or submeter on or before the due date therefor directly to the supplier thereof. 
 9.4 Other
Utilities. Subject to Landlord’s reasonable rules and regulations governing the same and as may be otherwise provided in Section 9.6, Tenant shall obtain and pay, as and when due, for all other utilities and services consumed in and/or
furnished to the Premises, together with all taxes, penalties, surcharges and maintenance charges pertaining thereto. 

  
 PAGE 13 

 9.5 Interruption or Curtailment of Utilities. When necessary by reason of accident or
emergency, or for repairs, alterations, replacements or improvements which in the reasonable judgment of Landlord are desirable or necessary to be made, Landlord reserves the right, upon as much prior notice to Tenant as is practicable under the
circumstances and no less than twenty-four (24) hours’ prior written notice except in the event of an emergency, to interrupt, curtail, or stop (i) the furnishing of hot and/or cold water, and (ii) the operation of the plumbing
and electric systems. Landlord shall exercise reasonable diligence to eliminate the cause of any such interruption, curtailment, stoppage or suspension, but there shall be no diminution or abatement of Rent or other compensation due from Landlord to
Tenant hereunder, nor shall this Lease be affected or any of Tenant’s obligations hereunder reduced, and Landlord shall have no responsibility or liability for any such interruption, curtailment, stoppage, or suspension of services or systems,
except as explicitly provided in Section 9.7 below. 
 9.6 Landlord’s Services. Subject to reimbursement pursuant to
Section 5.2 above, Landlord shall furnish Tenant with the following services in the Building: (a) water for use in the common lavatories and for ordinary premises and kitchenette use, cleaning and drinking purposes; (b) customary heat
and air conditioning (“HVAC Service”) in season and during Normal Business Hours (as hereinafter defined); (c) elevator service, and (d) janitorial services on Monday through Friday (except for Building Holidays).
In addition, Tenant shall have the right to use the loading dock and freight elevator services for the Building on a non-discriminatory, first-come, first served basis, it being understood that the use of the freight elevator and loading dock must
be scheduled in advance with Landlord but there shall be no charge for any such usage; (d) electricity in accordance with the terms and conditions of Section 9.1; (e) access to the Building for Tenant and its employees 24 hours per
day/7 day, per week, subject to the terms of this Lease and such protective services or monitoring systems, if any, as Landlord may reasonably impose, including, without limitation, sign-in procedures and/or presentation of identification cards; and
(f) such other services as Landlord reasonably determines are necessary or appropriate for the Property. As used herein, “Normal Business Hours” shall mean 8:00 A.M. to 6:00 P.M. on Monday through Friday and 8:00 A.M. to 1:00
P.M. on Saturdays, excepting Building Holidays. As used herein, “Building Holiday” shall mean New Year’s Day, Presidents Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day plus days observed by
the Commonwealth of Massachusetts or the City of Cambridge as legal holidays. Landlord shall not be required to furnish any HVAC Service outside of Normal Business Hours unless Landlord shall have received advance notice from Tenant requesting such
HVAC Service at least twenty-four (24) hours prior to the day such HVAC Service is requested. Tenant shall pay, as Additional Rent, the usual and customary charges established by Landlord from time-to-time for HVAC Service outside of Normal
Business Hours (the “Overtime HVAC Rate”). As of the Execution Date, the Overtime HVAC Rate is $50.00 per hour. If Landlord, at Tenant’s request, provides any services which are not Landlord’s express obligation
under this Lease, including, without limitation, any repairs which are Tenant’s responsibility pursuant to Section 10.1 below, Tenant shall pay Landlord, or such other party designated by Landlord, the cost of providing such service plus a
reasonable administrative charge. Except in emergencies, as reasonably determined by Landlord, Landlord shall use reasonable efforts to notify Tenant of Landlord’s estimate of the cost of providing such services and any associated
administrative charges prior to providing such service(s). If Tenant wishes to obtain such services which are not Landlord’s express obligation under this Lease from third party vendors other than Landlord, Tenant may do

  
 PAGE 14 

 
so, subject to Landlord’s reasonable approval of such services and provided that (i) any such third party vendors are approved by Landlord (which approval shall not be unreasonably
withheld), (ii) such third party vendors provide Landlord with evidence of amounts and types of insurance as may be reasonably required by Landlord, (iii) such third party vendors comply with the applicable rules and regulations for the
Building, and (iv) such third party vendors will not cause a labor disruption vis a vis other vendors or contractors in the Building, as determined by Landlord in Landlord’s reasonable discretion. 

9.7 Tenant’s Remedies in the Event of Service Interruption 

(a) Abatement of Base Rent. In the event that: (i) (a) there shall be an interruption, curtailment or suspension of any
utility service described above in this Section 9 or failure to perform any obligation required to be provided or performed by Landlord pursuant to Sections 9 or 10.2 (and no reasonably equivalent alternative service or supply is provided by
Landlord) that shall materially interfere with Tenant’s use and enjoyment of the Premises, or any portion thereof or (b) Tenant is denied access to the Premises (any such event, a “Service Interruption”), and
(ii) such Service Interruption shall continue for five (5) consecutive business days following receipt by Landlord of written notice (the “Service Interruption Notice”) from Tenant describing such Service
Interruption (“Abatement Service Interruption Cure Period”), and (iii) such Service Interruption shall not have been caused by Tenant Fault, as defined in Section 9.7(b) below (an event that satisfies the
foregoing conditions (i)-(iii) being referred to hereinafter as a “Material Service Interruption”) then, Tenant, subject to the next following sentence, shall be entitled to an equitable abatement of Base Rent and
Additional Rent based on the nature and duration of the Material Service Interruption and the area of the Premises affected, for any and all days following the Abatement Service Interruption Cure Period that the Material Service Interruption is
continuing. The Abatement Service Interruption Cure Period shall be extended by reason of any delays in Landlord’s ability to cure the Service Interruption in question caused by causes beyond Landlord’s reasonable control; provided,
however, that in no event shall the Abatement Service Interruption Cure Period be longer than ten (10) consecutive business days following receipt by Landlord of the Service Interruption Notice. 

(b) Tenant’s Termination Right. In the event that: (i) a Service Interruption occurs, and (ii) such Service
Interruption continues for a period of ninety (90) consecutive days after Landlord receives a Service Interruption Notice with respect to such Service Interruption (“Termination Service Interruption Cure Period”),
and (iii) such Service Interruption shall not have been caused by the default, negligence or willful misconduct of Tenant or any of the Tenant Parties or Tenant’s invitees (any such cause being referred to as “Tenant
Fault”), then Tenant shall have the right to terminate this Lease by giving a written termination notice to Landlord after the expiration of the Termination Service Interruption Cure Period. If such Service Interruption is cured within
ten (10) days (“Post-Termination Notice Cure Period”) after Landlord receives such termination notice, then Tenant shall have no right to terminate this Lease based upon such Service Interruption and such termination
notice shall be of no force or effect. If such Service Interruption is not cured within the Post-Termination Notice Cure Period, then the term of the Lease shall terminate as of the expiration of the Post-Termination Cure Period. The Termination
Service Interruption Cure Period and the Post-Termination Notice Cure Period shall each be extended by reason of any delays in Landlord’s ability to cure the Service Interruption in question caused by causes beyond Landlord’s reasonable
control; provided, however, that in no event shall the Post-Termination Notice Cure Period be longer than one hundred and fifty (150) days following receipt by Landlord of the Service Interruption Notice. 

  
 PAGE 15 

 (c) In the event of any Service Interruption, Landlord will use all commercially reasonable
efforts to restore any Service Interruption as soon as is reasonably practicable. 
 (d) The provisions of this Section 9.7 shall not
apply in the event of a Service Interruption caused by Casualty or Taking (see Section 15 hereof). 
 (e) The provisions of this
Section 9.7 set forth Tenant’s sole rights and remedies, both in law and in equity, in the event of any Service Interruption. 
 10.
MAINTENANCE AND REPAIRS 
 10.1 Maintenance and Repairs by Tenant. Tenant shall: (i) keep the Premises neat and clean
(ii) keep the Premises free of insects, rodents, vermin and other pests to the extent any infestation of the same is caused by any Tenant Party and (iii) keep the Premises in good repair, order and condition, including without limitation
the entire interior of the Premises, all electronic, phone and data cabling and related equipment that is installed by or for the exclusive benefit of the Tenant (whether located in the Premises or other portions of the Building), all fixtures,
equipment and lighting therein, electrical equipment wiring, doors, non-structural walls, windows and floor coverings, reasonable wear and tear and damage by Casualty excepted. Tenant shall be solely responsible, at Tenant’s sole cost and
expense, for the proper maintenance of (i) all supplemental heating, ventilation and air conditioning equipment which exclusively serve the Premises, (ii) any other equipment and appliances which exclusively serve the Premises
(iii) the emergency call systems located on the sixteenth (16th) floor of the Building and (iv) the security card access systems located on the sixteenth (16th) floor of the Building. Tenant agrees to provide regular maintenance by contract with a reputable qualified service contractor for all such equipment. Each such maintenance contract and
contractor shall be subject to Landlord’s reasonable approval. Tenant, at Landlord’s request, shall at reasonable intervals provide Landlord with copies of such contracts and maintenance and repair records and/or reports. 

10.2 Maintenance and Repairs by Landlord. Except as otherwise provided in Section 15, and subject to Tenant’s obligations in
Section 10.1 above, Landlord shall maintain and keep in reasonable condition the common Building systems and equipment (including, without limitation, sanitary, electrical, heating, air conditioning, fire/life safety, plumbing and other systems
servicing the Premises), foundation, the roof (and all components of the roof), Building structure, exterior walls, structural floor slabs and columns in good repair, order and condition consistent with comparable combination office and laboratory
facilities in the vicinity of the Premises. In addition, Landlord shall operate and maintain the Common Areas in substantially the same manner as comparable combination office and laboratory facilities in the vicinity of the Premises. 

  
 PAGE 16 

 10.3 Accidents to Sanitary and Other Systems. Tenant shall give to Landlord prompt notice
of any fire or accident in the Premises or in the Building and of any damage to, or defective condition in, any part or appurtenance of the Building including, without limitation, sanitary, electrical, ventilation, heating and air conditioning or
other systems located in, or passing through, the Premises. Except as otherwise provided in Section 15, and subject to Tenant’s obligations in Section 10.1 above, such damage or defective condition shall be remedied by Landlord with
reasonable diligence, but, subject to Section 14.5 below, if such damage or defective condition was caused by any of the Tenant Parties, the cost to remedy the same shall be paid by Tenant. 

10.4 Floor Load—Heavy Equipment. Tenant shall not place a load upon any floor of the Premises exceeding the floor load per square
foot of area which such floor was designed to carry and which is allowed by Legal Requirements. Landlord reserves the right to prescribe the weight and position of all safes, heavy machinery, heavy equipment, freight, bulky matter or fixtures
(collectively, “Heavy Equipment”), which shall be placed so as to distribute the weight. Heavy Equipment shall be placed and maintained by Tenant at Tenant’s expense in settings sufficient in Landlord’s reasonable judgment
to absorb and prevent vibration, noise and annoyance. Tenant shall not move any Heavy Equipment into or out of the Building without giving Landlord prior written notice thereof and observing all of Landlord’s Rules and Regulations with respect
to the same. If such Heavy Equipment requires special handling, Tenant agrees to employ only persons holding a Master Rigger’s License to do said work, and that all work in connection therewith shall comply with Legal Requirements. Any such
moving shall be at the sole risk and hazard of Tenant and Tenant will defend, indemnify and save Landlord Parties harmless from and against any and all claims, damages, losses, penalties, costs, expenses and fees (including without limitation
reasonable legal fees) (collectively, “Claims”) resulting directly or indirectly from such moving. Proper placement of all Heavy Equipment in the Premises shall be Tenant’s responsibility. 

11. ALTERATIONS AND IMPROVEMENTS BY TENANT 

11.1 Landlord’s Consent Required. Tenant shall not make any alterations,decorations, installations, removals, additions or
improvements (“Alterations”) in or to the Premises without Landlord’s prior written approval of the contractor(s), written plans and specifications and a time schedule therefor. Unless otherwise expressly agreed to by Landlord
in writing, such plans and specifications shall be consistent with the Construction Rules and Regulations (hereinafter defined) attached hereto as Exhibit 8-2. Landlord reserves the right to require that Tenant use Landlord’s preferred
vendor(s) for any Alterations that involve roof penetrations, alarm tie-ins, sprinklers, fire alarm and other life safety equipment. Tenant shall not make any amendments or additions to plans and specifications approved by Landlord without
Landlord’s prior written consent. Landlord’s approval of non-structural Alterations shall not be unreasonably withheld, conditioned or delayed. Notwithstanding the foregoing, Landlord may withhold its consent in its sole discretion
(a) to any Alteration to or affecting the fixed lab benches, fume hoods, roof and/or building systems, (b) with respect to matters of aesthetics relating to Alterations to or affecting the exterior of the Building, and (c) to any
Alteration affecting the Building structure. Tenant shall be responsible for all elements of the design of Tenant’s plans (including, without limitation, compliance with Legal Requirements, functionality of design, the structural integrity of
the design, the configuration of the Premises and the placement of Tenant’s furniture, appliances and equipment), and Landlord’s approval of Tenant’s plans shall in no event relieve Tenant of the responsibility for such design. In
seeking Landlord’s approval, Tenant shall provide Landlord, at least fourteen (14) days in advance of any proposed construction, with plans, specifications, bid proposals, certified stamped engineering 

  
 PAGE 17 

 
drawings and calculations by Tenant’s engineer of record or architect of record, (including connections to the Building’s structural system, modifications to the Building’s
envelope, non-structural penetrations in slabs or walls, and modifications or tie-ins to life safety systems), work contracts, requests for laydown areas and such other information concerning the nature and cost of the alterations as Landlord may
reasonably request. Landlord shall have no liability or responsibility for any claim, injury or damage alleged to have been caused by the particular materials (whether building standard or non-building standard), appliances or equipment selected by
Tenant in connection with any work performed by or on behalf of Tenant. Except as otherwise expressly set forth herein, all Alterations shall be done at Tenant’s sole cost and expense and at such times and in such manner as Landlord may from
time to time reasonably designate. If Tenant shall make any Alterations, then (unless otherwise stated by Landlord in its consent to the performance of such Alteration) Landlord may elect to require Tenant at the expiration or sooner termination of
the Term to restore the Premises to substantially the same condition as existed immediately prior to the Alterations (including, without limitation, the removal of cabling and any other low voltage wiring). Notwithstanding the foregoing, Landlord
agrees: (i) to specify whether any Initial Alterations made by Tenant pursuant to the provisions of Exhibit 3 will need to be removed by Tenant at the expiration or sooner termination of the Term at the time that Landlord consents to such
Initial Alterations and, (ii) with respect to any Alterations other than the Initial Alterations, to specify whether any such Alterations will need to be removed by Tenant at the expiration or sooner termination of the Term if Tenant requests
that Landlord make such election at the time Tenant submits the plans and specifications for such Alterations to Landlord. Tenant shall provide Landlord with reproducible record drawings (in CAD format) of all Alterations within sixty (60) days
after completion thereof. Notwithstanding the foregoing, provided that Tenant provides Landlord at least five (5) business days’ prior written notice of such Alterations, Landlord’s consent shall not be required with respect to the
following Alterations: (i) any interior cosmetic or decorative Alteration (such as the installation of paint or wall coverings) or (ii) other non-structural alterations which (a) do not affect the Building’s structure or base
building systems, (b) are not readily visible from the exterior of the Premises and (c) cost less than $100,000.00 in the aggregate in any one instance. In the event that Tenant’s proposed Alterations include the installation of any
HVAC heat pump units, Tenant shall, at its sole cost and expense, tie such heat pump units into the Building’s emergency management system. 

11.2 After-Hours. Landlord and Tenant recognize that to the extent Tenant elects to perform some or all of the Alterations during times
other than normal construction hours (i.e., Monday-Friday, 7:00 a.m. to 6:00 p.m., excluding Building Holidays), Landlord may need to make arrangements to have supervisory personnel on site. Accordingly, Landlord and Tenant agree as follows: Tenant
shall give Landlord at least two (2) business days’ prior written notice of any time outside of normal construction hours when Tenant intends to perform any Alterations (the “After-Hours Work”). Tenant shall reimburse
Landlord, within ten (10) days after demand therefor, for the cost of Landlord’s supervisory personnel overseeing the After-Hours Work, provided that such costs constitute Permitted Costs for which Tenant may use the Allowance, subject to
the Outside Draw Date (as defined in Section 6 of Exhibit 3). In addition, if construction during normal construction hours unreasonably disturbs other tenants of the Building, in Landlord’s bona fide business judgment, Landlord may
require Tenant to stop the performance of Alterations during normal construction hours and to perform the same after hours, subject to the foregoing requirement to pay for the cost of Landlord’s supervisory personnel. 

  
 PAGE 18 

 11.3 Harmonious Relations. Tenant agrees that it will not use any contractors and/or
materials if their use will create any difficulty, whether in the nature of a labor dispute or otherwise, with other contractors and/or labor engaged by Tenant or Landlord or others in the construction, maintenance and/or operation of the Building,
the Property or any part thereof. In the event of any such difficulty, upon Landlord’s request, Tenant shall cause all contractors, mechanics or laborers causing such difficulty to leave the Property immediately. 

11.4 Liens. No Alterations shall be undertaken by Tenant until (i) Tenant has made provision for written waiver of liens from all
contractors for such Alteration and taken other appropriate protective measures approved and/or required by Landlord; and, (ii) with respect to any Alterations involving total estimated costs in excess of $450,000, Tenant has procured
appropriate surety payment and performance bonds which shall name Landlord as an additional obligee and has filed lien bond(s) (in jurisdictions where available) on behalf of such contractors. Notwithstanding the foregoing, Landlord agrees that,
with respect to the Initial Alterations, Tenant shall not be required to procure such surety payment and performance bonds or file such lien bonds. Any mechanic’s lien filed against the Premises or the Building for work claimed to have been
done for, or materials claimed to have been furnished to, Tenant shall be discharged by Tenant within ten (10) business days thereafter, at Tenant’s expense by filing the bond required by law or otherwise. 

11.5 General Requirements. Unless Landlord and Tenant otherwise agree in writing, Tenant shall (a) procure or cause others to
procure on its behalf all necessary permits before undertaking any Alterations in the Premises (and provide copies thereof to Landlord); (b) perform all of such Alterations in a good and workmanlike manner, employing materials of good quality
and in compliance with Landlord’s construction rules and regulations as provided in writing to Tenant, all insurance requirements of this Lease, and Legal Requirements; and (c) defend, indemnify and hold the Landlord Parties harmless from
and against any and all Claims occasioned by or growing out of such Alterations, except to the extent such Claims result from the negligence or willful misconduct of Landlord Parties. 

11.6 Construction Management Fee. With respect to any Alterations (including the Initial Alterations) made by Tenant, (1) Tenant
shall pay an administration and supervision fee to Landlord or, at Landlord’s direction, to Landlord’s Building manager equal to one percent (1%) of the sum of the hard costs and costs of engineering and design associated with such
Alterations and (2) Tenant shall reimburse Landlord for any reasonable third party fees (e.g., the cost of reviewing Tenant’s plans by a structural engineer, MEP engineer and/or security consultant, if Landlord reasonably deems that such
review is necessary) incurred by Landlord in connection with such Alterations. 

  
 PAGE 19 

 12. SIGNAGE 

12.1 Restrictions. Tenant shall have the right to install Building standard signage identifying Tenant’s business at the entrance
to the Premises, which signage shall be subject to Landlord’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed). Subject to the foregoing, and subject to Section 12.2 below, Tenant shall not
place or suffer to be placed or maintained on the exterior of the Premises, or any part of the interior visible from the exterior thereof, any sign, banner, advertising matter or any other thing of any kind (including, without limitation, any
hand-lettered advertising), and shall not place or maintain any decoration, letter or advertising matter on the glass of any window or door of the Premises without first obtaining Landlord’s written approval. No signs or blinds may be put on or
in any window or elsewhere if visible from the exterior of the Building. 
 12.2 Building Directory. Landlord shall list Tenant within
the directory in the Building lobby at Landlord’s sole cost and expense. Subject to reasonable limits on the number of lines on the directory Landlord can provide and all such additional signage in the lobby directory, Landlord shall add the
names of any approved subtenants or licensees occupying any portion of the Premises at Tenant’s sole cost and expense. Tenant, at Tenant’s sole cost and expense, may install building standard signage at the entrance to Tenant’s
Premises on the first floor in accordance with plans and specifications therefor that have been approved in advance, in writing by Landlord. 
 13.
ASSIGNMENT, MORTGAGING AND SUBLETTING 
 13.1 Landlord’s Consent Required. Tenant shall not mortgage or encumber this Lease
or in whole or in part whether at one time or at intervals, operation of law or otherwise. Except as expressly otherwise set forth herein, Tenant shall not, without Landlord’s prior written consent, assign, sublet, license or transfer this
Lease or the Premises in whole or in part whether by changes in more than fifty percent (50%) of the ownership or control of Tenant, whether at one time or at intervals, by sale or transfer of stock, partnership or beneficial interests,
operation of law or otherwise, or permit the occupancy of all or any portion of the Premises by any person or entity other than Tenant’s employees (each of the foregoing, a “Transfer”). Any purported Transfer made without
Landlord’s consent, if required hereunder, shall be void and confer no rights upon any third person, provided that if there is a Transfer, Landlord may collect rent from the transferee without waiving the prohibition against Transfers,
accepting the transferee, or releasing Tenant from full performance under this Lease. In the event of any Transfer in violation of this Section 13, Landlord shall have the right to terminate this Lease upon thirty (30) days’ written
notice to Tenant given within sixty (60) days after receipt of written notice from Tenant to Landlord of any Transfer, or within one (1) year after Landlord first learns of the Transfer if no notice is given. No Transfer shall relieve
Tenant of its primary obligation as party Tenant hereunder, nor shall it reduce or increase Landlord’s obligations under this Lease. 

13.2 Landlord’s Recapture Right 

(a) Subject to Section 13.7 below, Tenant shall, prior to offering or advertising the Premises or any portion thereof for a Transfer, give
a written notice (the “Recapture Notice”) to Landlord which: (i) states that Tenant desires to make a Transfer, (ii) identifies the affected portion of the Premises (the “Recapture Premises”),
(iii) identifies the period of time (the “Recapture Period”) during which Tenant proposes to sublet the Recapture Premises, or indicates that Tenant proposes to assign its interest in this Lease, and (iv) offers to
Landlord to terminate this Lease with respect to the Recapture Premises (in the case of a proposed assignment of Tenant’s interest in this Lease or a subletting for the remainder of the term of this

  
 PAGE 20 

 
Lease) or to suspend the Term for the Recapture Period (i.e. the Term with respect to the Recapture Premises shall be terminated during the Recapture Period and Tenant’s rental obligations
shall be proportionately reduced). Landlord shall have fifteen (15) business days within which to respond to the Recapture Notice. 

(b) If Tenant does not enter into a Transfer on the terms and conditions contained in the Recapture Notice on or before the date which is one
hundred eighty (180) days after the earlier of: (x) the expiration of the 15-business day period specified in Section 13.2(a) above, or (y) the date that Landlord notifies Tenant that Landlord will not accept Tenant’s offer
contained in the Recapture Notice, time being of the essence, then prior to entering into any Transfer after such 180-day period, Tenant must deliver to Landlord a new Recapture Notice in accordance with Section 13.2(a) above 

(c) Notwithstanding anything to the contrary contained herein, if Landlord notifies Tenant that it accepts the offer contained in the Recapture
Notice or any subsequent Recapture Notice, Tenant shall have the right, for a period of fifteen (15) days following receipt of such notice from Landlord, time being of the essence, to notify Landlord in writing that it wishes to withdraw
such offer and this Lease shall continue in full force and effect. 
 13.3 Standard of Consent to Transfer. If Landlord does not
timely give written notice to Tenant accepting a Recapture Offer or declines to accept the same, then Landlord agrees that, subject to the provisions of this Section 13, Landlord shall not unreasonably withhold, condition or delay its consent
to a Transfer and otherwise on the terms contained in the Recapture Notice to an entity which will use the Premises for the Permitted Uses and, in Landlord’s reasonable opinion: (a) has a tangible net worth and other financial indicators
sufficient to meet the Transferee’s obligations under the Transfer instrument in question; (b) has a business reputation compatible with the operation of a combination laboratory, research, development and office building; and (c) the
intended use of such entity does not violate any restrictive use provisions then in effect with respect to space in the Building. 
 13.4
Listing Confers no Rights. The listing of any name other than that of Tenant, whether on the doors of the Premises or on the Building directory, or otherwise, shall not operate to vest in any such other person, firm or corporation any right or
interest in this Lease or in the Premises or be deemed to effect or evidence any consent of Landlord. 
 13.5 Profits In Connection with
Transfers. Except in connection with a Transfer that does not require Landlord’s consent pursuant to Section 13.7, Tenant shall, within thirty (30) days of receipt thereof, pay to Landlord fifty percent (50%) of any rent, sum
or other consideration to be paid or given in connection with any Transfer, either initially or over time, after deducting actual out-of-pocket legal, and brokerage expenses, architectural and engineering fees, and construction costs and
construction allowances incurred by Tenant in good faith and unamortized improvements paid for by Tenant in connection therewith, in excess of Rent hereunder as if such amount were originally called for by the terms of this Lease as Additional Rent.

  
 PAGE 21 

 13.6 Prohibited Transfers. Notwithstanding any contrary provision of this Lease, Tenant
shall have no right to make a Transfer unless on both (i) the date on which Tenant notifies Landlord of its intention to enter into a Transfer and (ii) the date on which such Transfer is to take effect, Tenant is not in default of any of
its obligations under this Lease, beyond applicable notice and cure periods. Notwithstanding anything to the contrary contained herein, Tenant agrees that in no event shall Tenant make a Transfer without Landlord’s written consent (which may be
withheld in Landlord’s sole discretion) to (a) any government agency; (b) any tenant, subtenant or occupant of other space in the Building; or (c) any entity with whom Landlord shall have negotiated for space in the Property in
the four (4) months immediately preceding such proposed Transfer. 
 13.7 Exceptions to Requirement for Consent. Notwithstanding
anything to the contrary herein contained, Tenant shall have the right, without obtaining Landlord’s consent and without giving Landlord a Recapture Notice, to make a Transfer to (a) an Affiliated Entity (hereinafter defined) so long as
such entity remains in such relationship to Tenant for at least one (1) year after the Transfer to such Affiliated Entity, and (b) a Successor, provided that prior to or simultaneously with any such Transfer, such Affiliated Entity or
Successor, as the case may be, and Tenant execute and deliver to Landlord an assignment and assumption agreement in form and substance reasonably acceptable to Landlord whereby such Affiliated Entity or Successor, as the case may be, shall agree to
be independently bound by and upon all the covenants, agreements, terms, provisions and conditions set forth in the Lease on the part of Tenant to be performed, and whereby such Affiliated Entity or Successor, as the case may be, shall expressly
agree that the provisions of this Section 13 shall, notwithstanding such Transfer, continue to be binding upon it with respect to all future Transfers. For the purposes hereof, an “Affiliated Entity” shall be defined as any
entity (a) that has a net worth and other financial indicators demonstrating such entity’s ability to perform all of Tenant’s obligations hereunder, as evidenced by audited financial statements; and (b) which is controlled by, is
under common control with, or which controls Tenant. For the purposes hereof, a “Successor” shall be defined as any entity into or with which Tenant is merged or with which Tenant is consolidated or which acquires all or
substantially all of Tenant’s stock or assets, provided that the surviving entity shall have a net worth and other financial indicators sufficient to meet Tenant’s obligations hereunder. 

13.8 Expenses Incurred by Landlord. Tenant shall promptly reimburse Landlord for the reasonable expenses (including reasonable
attorneys’ fees) incurred by Landlord in connection with Tenant’s request for Landlord to give its consent to any Transfer; provided, however, that the maximum amount payable by Tenant on account of fees incurred by Landlord with respect
to any request by Tenant for Landlord’s consent to a proposed Transfer shall be $2,500, except: (i) where the Transfer is a sub-sublease of any tier, or (x) where, at Tenant’s request, the parties enter into a mutually acceptable
amendment to the Lease in connection with such proposed Transfer. 
 14. INSURANCE; INDEMNIFICATION; EXCULPATION 

14.1 Tenant’s Insurance. 

(a) Tenant shall procure, pay for and keep in force throughout the Term (and for so long thereafter as Tenant remains in occupancy of the
Premises) commercial general liability insurance insuring Tenant on an occurrence basis against all claims and demands for

personal injury liability (including bodily injury, sickness, disease, and death) or damage to property which may be claimed to have occurred from and after the time any of the Tenant Parties
shall first enter the Premises, of not less than Two Million Dollars ($2,000,000), and from time to time thereafter shall be not less than such higher amounts, if procurable, as may be reasonably required by Landlord. Tenant shall also carry
umbrella liability coverage in an amount of no less than Three Million Dollars ($3,000,000). Such policy shall also include contractual liability coverage. Such insurance policy(ies) shall name Landlord, Landlord’s managing agent and persons

Tenant will give Landlord notice of any modification to Tenant’s Insurance Policies that materially adversely affects Landlord within five (5) business days after such modification. Tenant’s Insurance Policies may include deductibles
in an amount no greater than commercially reasonable amounts. On or before the date on which any of the Tenant Parties shall first enter the Premises

the Landlord Parties harmless from and against any and all Claims asserted by or on behalf of any person, firm, corporation or public authority arising from:

14.3 Property of Tenant. Tenant covenants and agrees that, to the maximum extent permitted by Legal Requirements, all of Tenant’s
Property at the Premises shall be at the sole risk and hazard of Tenant, and that if the whole or any part thereof shall be damaged, destroyed, stolen or removed from any cause or reason whatsoever, no part of said damage or loss shall be charged
to, or borne by, Landlord, except, subject to Section 14.5 hereof, to the extent such damage or loss is due to the negligence or willful misconduct of any of the Landlord Parties. 

14.4 Limitation of Landlord’s Liability for Damage or Injury. Landlord shall not be liable for any injury or damage to persons or
property resulting from fire, explosion, falling plaster, steam, gas, air contaminants or emissions, electricity, electrical or electronic emanations or disturbance, water, rain or snow or leaks from any part of the Building or from the pipes,

negligence or willful misconduct of any of the Landlord Parties, and then, where notice and an opportunity to cure are appropriate 

  
 PAGE 24 

 
(i.e., where Tenant has an opportunity to know or should have known of such condition sufficiently in advance of the occurrence of any such injury or damage resulting therefrom as would have
enabled Landlord to prevent such damage or loss had Tenant notified Landlord of such condition) only after (i) notice to Landlord of the condition claimed to constitute negligence or willful misconduct, and (ii) the expiration of a
reasonable time after such notice has been received by Landlord without Landlord having commenced to take all reasonable and practicable means to cure or correct such condition; Tenant shall take all reasonably prudent temporary measures and
safeguards to prevent any injury, loss or damage to persons or property. Notwithstanding the foregoing, in no event shall any of the Landlord Parties be liable for any loss which is covered by insurance policies actually carried or required to be so
carried by Tenant or any Tenant Parties under this Lease; nor shall any of the Landlord Parties be liable for any such damage caused by other tenants or persons in the Building or caused by operations in construction of any private, public, or
quasi-public work; nor shall any of the Landlord Parties be liable for any latent defect in the Premises or in the Building; provided, however, that the foregoing shall not relieve Landlord of its maintenance and repair obligations as set forth in
Section 10.2 of the Lease (including, without limitation, the repair of any latent defects in the portions of the Building required to be maintained by Landlord pursuant to Section 10.2). 

14.5 Waiver of Subrogation; Mutual Release. Landlord and Tenant each hereby waives on behalf of itself and its property insurers (none
of which shall ever be assigned any such claim or be entitled thereto due to subrogation or otherwise) any and all rights of recovery, claim, action, or cause of action against the other and its agents, officers, servants, partners, shareholders, or
employees (collectively, the “Related Parties”) for any loss or damage that may occur to or within the Premises or the Building or any improvements thereto, or any personal property of such party therein which is insured against
under any property insurance policy actually being maintained by the waiving party from time to time, even if not required hereunder, or which would be insured against under the terms of any insurance policy required to be carried or maintained by
the waiving party hereunder, whether or not such insurance coverage is actually being maintained, including, in every instance, such loss or damage that may be caused by the negligence of the other party hereto and/or its Related Parties. Landlord
and Tenant each agrees to cause appropriate clauses to be included in its property insurance policies necessary to implement the foregoing provisions. 

14.6 Tenant’s Acts—Effect on Insurance. Tenant shall not do or permit any Tenant Party to do any act or thing upon the
Premises or elsewhere in the Building which will invalidate or be in conflict with any insurance policies covering the Building and the fixtures and property therein. If by reason of the failure of Tenant to comply with the provisions hereof the
insurance rate applicable to any policy of insurance shall at any time thereafter be higher than it otherwise would be, Tenant shall reimburse Landlord upon demand for that part of any insurance premiums which shall have been charged because of such
failure by Tenant, within ten (10) days after receipt of an invoice therefor. In addition, Tenant shall reimburse Landlord for any increase in insurance premium arising as a result of Tenant’s use and/or storage of any Hazardous Materials
in the Premises. 
 14.7 Landlord’s Insurance. Landlord shall maintain all risk property and, if applicable, sprinkler damage
insurance covering the full replacement cost of the Building. Landlord shall further procure and maintain commercial general liability insurance with a single loss limit of not less than $2,000,000 for bodily injury and property damage with respect
to the Property. 

  
 PAGE 25 

 15. CASUALTY; TAKING 

15.1 Damage. If the Premises or access thereto is damaged in whole or part because of fire or other insured casualty
(“Casualty”), or if the Premises or access thereto is subject to a taking in connection with the exercise of any power of eminent domain, condemnation, or purchase under threat or in lieu thereof (any of the foregoing, a
“Taking”), then unless this Lease is terminated in accordance with Section 15.2 below, Landlord shall restore the Building and the Premises and the access thereto to substantially the same condition as existed as of the Term
Commencement Date, or in the event of a partial Taking which affects the Building and the Premises or access thereto, restore the remainder of the Building and the Premises or access thereto not so Taken to substantially the same condition as is
reasonably feasible. Within sixty (60) days after the occurrence of a Casualty, Landlord shall cause a general contractor selected by Landlord to provide Landlord and Tenant with a written estimate of the amount of time (the “Estimated
Restoration Period”) required using standard working methods to complete the repair and restoration of the Building and the Premises and the access thereto in accordance with this Section 15.1. If, in Landlord’s reasonable
judgment, any element of the Tenant-Insured Improvements can more effectively be restored as an integral part of Landlord’s restoration of the Building or the Premises, such restoration shall also be made by Landlord, but at Tenant’s sole
cost and expense. Subject to rights of Mortgagees, Tenant Delays, Legal Requirements then in existence and to delays for adjustment of insurance proceeds or Taking awards, as the case may be, and instances of Landlord’s Force Majeure, Landlord
shall substantially complete such restoration on or before the later of (i) two hundred seventy (270) days after Landlord’s receipt of all required permits therefor with respect to substantial reconstruction of at least 50% of the
Building, or, within one hundred eighty (180) days after Landlord’s receipt of all required permits therefor in the case of restoration of less than 50% of the Building and (ii) the last day of the Estimated Restoration Period. Upon
substantial completion of such restoration by Landlord, Tenant shall use diligent efforts to complete restoration of the Premises to substantially the same condition as existed immediately prior to such Casualty or Taking, as the case may be, as
soon as reasonably possible. Tenant agrees to cooperate with Landlord in such manner as Landlord may reasonably request to assist Landlord in collecting insurance proceeds due in connection with any Casualty which affects the Premises or the
Building. In no event shall Landlord be required to expend more than the Net (hereinafter defined) insurance proceeds Landlord receives for damage to the Premises and/or the Building or the Net Taking award attributable to the Premises and/or the
Building. “Net” means the insurance proceeds or Taking award actually paid to Landlord (and not paid over to a Mortgagee) less all costs and expenses, including adjusters and attorney’s fees, of obtaining the same. Except as
Landlord may elect pursuant to this Section 15.1, under no circumstances shall Landlord be required to repair any damage to, or make any repairs to or replacements of, any Tenant-Insured Improvements. During any period of time that all or any
portion of the Premises is rendered untenantable or inaccessible as a result of a Casualty or Taking, Base Rent and Additional Rent shall abate for the portion of the Premises that is untenantable or inaccessible and not used by Tenant. 

  
 PAGE 26 

 15.2 Termination Rights. 

(a) Landlord’s Termination Rights. Landlord may terminate this Lease upon thirty (30) days’ prior written notice to
Tenant if: 
 (i) any material portion of the Building or any material means of access thereto is taken; 

(ii) more than thirty-five percent (35%) of the Building is damaged by Casualty; or 

(iii) the Estimated Restoration Period exceeds two hundred seventy (270) days. 

(b) Tenant’s Termination Right. If (i) Landlord is so required but fails to complete restoration of the Premises within the
time frames and subject to the conditions set forth in Section 15.1 above or (ii) the Estimated Restoration Period exceeds two hundred seventy (270) days, then Tenant may terminate this Lease upon thirty (30) days’ written
notice to Landlord; provided, however, that if Landlord completes such restoration within thirty (30) days after receipt of any such termination notice, such termination notice shall be null and void and this Lease shall continue in full force
and effect. The remedies set forth in this Section 15.2(b) and in Section 15.2(c) below are Tenant’s sole and exclusive rights and remedies based upon Landlord’s failure to complete the restoration of the Premises as set forth
herein. Notwithstanding anything to the contrary contained herein, Tenant shall not have the right to terminate this Lease pursuant to this Section 15 if the Casualty was caused by the intentional misconduct of any Tenant Party. 

(c) Either Party May Terminate. In the case of any Casualty or Taking affecting the Premises and occurring during the last twelve
(12) months of the Term, then (i) if such Casualty or Taking results in more than twenty-five percent (25%) of the floor area of the Premises being unsuitable for the Permitted Uses, or (ii) the damage to the Premises costs more
than $250,000 to restore, then either Landlord or Tenant shall have the option to terminate this Lease upon thirty (30) days’ written notice to the other. In addition, if Landlord’s Mortgagee does not release sufficient insurance
proceeds to cover the cost of Landlord’s restoration obligations, then Landlord shall (i) notify Tenant thereof, and (ii) have the right to terminate this Lease. If Landlord does not terminate this Lease pursuant to the previous
sentence and such notice by Landlord does not include an agreement by Landlord to pay for the difference between the cost of such restoration and such released insurance proceeds, then Tenant may terminate this Lease by written notice to Landlord on
or before the date that is thirty (30) days after such written notice. Notwithstanding anything to the contrary contained in this Section 15, in no event may Tenant elect to terminate this Lease hereunder if the Casualty that would
otherwise give rise to such right results from the willful misconduct of Tenant, its agents, contractors, or employees. 
 (d) Automatic
Termination. In the case of a Taking of the entire Premises, then this Lease shall automatically terminate as of the date of possession by the Taking authority. 

15.3 Taking for Temporary Use. If the Premises are Taken for temporary use, this Lease and Tenant’s obligations, including without
limitation the payment of Rent, shall continue. For purposes hereof, a “Taking for temporary use” shall mean a Taking of ninety (90) days or less. 

  
 PAGE 27 

 15.4 Disposition of Awards. Except for any separate award for Tenant’s movable trade
fixtures, relocation expenses, and unamortized leasehold improvements paid for by Tenant (provided that the same may not reduce Landlord’s award), all Taking awards to Landlord or Tenant shall be Landlord’s property without Tenant’s
participation, and Tenant hereby assigns to Landlord Tenant’s interest, if any, in such award. Tenant may pursue its own claim against the Taking authority. 

16. ESTOPPEL CERTIFICATE. 
 Tenant shall
at any time and from time to time upon not less than ten (10) business days’ prior written notice from Landlord, execute, acknowledge and deliver to Landlord a statement in writing certifying that this Lease is unmodified and in full force
and effect (or if there have been modifications, that the same is in full force and effect as modified and stating the modifications), and the dates to which Rent has been paid in advance, if any, stating whether or not Landlord is in default in
performance of any covenant, agreement, term, provision or condition contained in this Lease and, if so, specifying each such default, and such other facts as Landlord may reasonably request, it being intended that any such statement delivered
pursuant hereto may be relied upon by any prospective purchaser of the Building or of any interest of Landlord therein, any Mortgagee or prospective Mortgagee thereof, any lessor or prospective lessor thereof, any lessee or prospective lessee
thereof, or any prospective assignee of any mortgage thereof. Time is of the essence with respect to any such requested certificate, Tenant hereby acknowledging the importance of such certificates in mortgage financing arrangements,
prospective sales and the like. 
 17. HAZARDOUS MATERIALS 

17.1 Prohibition. Tenant shall not, without the prior written consent of Landlord, bring or permit to be brought or kept in or on the
Premises or elsewhere in the Building or the Property (i) any inflammable, combustible or explosive fluid, material, chemical or substance (except for standard office supplies stored in proper containers); and (ii) any Hazardous Material
(hereinafter defined). Landlord shall have the right, from time to time, to inspect the Premises for compliance with the terms of this Section 17.1. 

17.2 Environmental Laws. For purposes hereof, “Environmental Laws” shall mean all laws, statutes, ordinances, rules and
regulations of any local, state or federal governmental authority having jurisdiction concerning environmental, health and safety matters, including but not limited to any discharge by any of the Tenant Parties into the air, surface water, sewers,
soil or groundwater of any Hazardous Material (hereinafter defined) whether within or outside the Premises, including, without limitation (a) the Federal Water Pollution Control Act, 33 U.S.C. Section 1251 et seq., (b) the Federal
Resource Conservation and Recovery Act, 42 U.S.C. Section 6901 et seq., (c) the Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C. Section 9601 et seq., (d) the Toxic Substances Control Act of 1976,
15 U.S.C. Section 2601 et seq., and (e) Chapter 21E of the General Laws of Massachusetts. Tenant, at its sole cost and expense, shall comply with (i) Environmental Laws, and (ii) any rules, requirements and safety procedures of
the Massachusetts Department of Environmental Protection, the City of Cambridge and any insurer of the Building or the Premises with respect to Tenant’s use, storage and disposal of any Hazardous Materials. 

  
 PAGE 28 

 17.3 Hazardous Material Defined. As used herein, the term “Hazardous
Material” means asbestos, oil or any hazardous, radioactive or toxic substance, material or waste or petroleum derivative which is or becomes regulated by any Environmental Law, including without limitation live organisms, viruses and
fungi, medical waste and any so-called “biohazard” materials. The term “Hazardous Material” includes, without limitation, oil and/or any material or substance which is designated as a “hazardous substance,”
“hazardous material,” “oil,” “hazardous waste” or toxic substance under any Environmental Law. 
 17.4
Testing. If any Mortgagee or governmental authority requires testing to determine whether there has been any release of Hazardous Materials and such testing is required as a result of the acts or omissions of any of the Tenant Parties, then
Tenant shall reimburse Landlord upon demand, as Additional Rent, for the reasonable costs thereof, together with interest at the Default Rate until paid in full. Tenant shall execute affidavits, certifications and the like, as may be reasonably
requested by Landlord from time to time concerning Tenant’s best knowledge and belief concerning the presence of Hazardous Materials in or on the Premises, the Building or the Property. 

17.5 Tenant Indemnity 
 (a)
Tenant hereby covenants and agrees to indemnify, defend and hold the Landlord Parties harmless from and against any and all Claims against any of the Landlord Parties arising out of contamination of any part of the Property or other adjacent
property, which contamination arises as a result of: (i) the presence of Hazardous Material in the Premises, the presence of which is caused by any act or omission of any of the Tenant Parties, or (ii) from a breach by Tenant of its
obligations under this Section 17. This indemnification of the Landlord Parties by Tenant includes, without limitation, reasonable costs incurred in connection with any investigation of site conditions or any cleanup, remedial, removal or
restoration work required by any federal, state or local governmental agency or political subdivision because of Hazardous Material present in the soil or ground water on or under the Building based upon the circumstances identified in the first
sentence of this Section 17.5. The indemnification and hold harmless obligations of Tenant under this Section 17.5 shall survive the expiration or any earlier termination of this Lease. Without limiting the foregoing, if the presence of
any Hazardous Material in the Building or otherwise in the Property is caused or permitted by any of the Tenant Parties and results in any contamination of any part of the Property or any adjacent property, Tenant shall promptly take all actions at
Tenant’s sole cost and expense as are necessary to return the Property and/or the Building or any adjacent property to their condition as of the date of this Lease, provided that Tenant shall first obtain Landlord’s written approval of
such actions, which approval shall not be unreasonably withheld, conditioned or delayed so long as such actions, in Landlord’s reasonable discretion, would not potentially have any adverse effect on the Property, and, in any event, Landlord
shall not withhold its approval of any proposed actions which are required by applicable Environmental Laws. The provisions of this Section 17.5 shall survive the expiration or earlier termination of the Lease. 

  
 PAGE 29 

 (b) Without limiting the obligations set forth in Section 17.5(a) above, if any Hazardous
Material is in, on, under, at or about the Building or the Property as a result of the acts or omissions of any of the Tenant Parties and results in any contamination of any part of the Property or any adjacent property that is in violation of any
applicable Environmental Law or that requires the performance of any response action pursuant to any Environmental Law, Tenant shall promptly take all actions at Tenant’s sole cost and expense as are necessary to reduce such Hazardous Material
to amounts below any applicable Reportable Quantity, any applicable Reportable Concentration and any other applicable standard set forth in any Environmental Law; provided that Tenant shall first obtain Landlord’s written approval of such
actions, which approval shall not be unreasonably withheld, conditioned or delayed so long as such actions would not be reasonably expected to have an adverse effect on the market value or utility of the Property for the Permitted Uses, and in any
event, Landlord shall not withhold its approval of any proposed actions which are required by applicable Environmental Laws (such approved actions, “Tenant’s Remediation”). 

(c) In the event that Tenant fails to complete Tenant’s Remediation prior to the end of the Term, then: 

(i) until the completion of Tenant’s Remediation (as evidenced by the certification of Tenant’s Licensed Site Professional (as such
term is defined by applicable Environmental Laws), who shall be reasonably acceptable to Landlord) (the “Remediation Completion Date”), Tenant shall pay to Landlord, with respect to the portion of the Premises which reasonably
cannot be occupied by a new tenant until completion of Tenant’s Remediation, (A) Additional Rent on account of Expenses and Taxes and (B) Base Rent in an amount equal to the greater of (1) the fair market rental value of such
portion of the Premises (determined in substantial accordance with the process described in Section 1.2 above), and (2) Base Rent attributable to such portion of the Premises in effect immediately prior to the end of the Term; and 

(ii) Tenant shall maintain responsibility for Tenant’s Remediation and Tenant shall complete Tenant’s Remediation as soon as
reasonably practicable in accordance with Environmental Laws. If Tenant does not diligently pursue completion of Tenant’s Remediation, Landlord shall have the right to either (A) assume control for overseeing Tenant’s Remediation, in
which event Tenant shall pay all reasonable costs and expenses of Tenant’s Remediation (it being understood and agreed that all costs and expenses of Tenant’s Remediation incurred pursuant to contracts entered into by Tenant shall be
deemed reasonable) within thirty (30) days of demand therefor (which demand shall be made no more often than monthly), and Landlord shall be substituted as the party identified on any governmental filings as the party responsible for the
performance of such Tenant’s Remediation or (B) require Tenant to maintain responsibility for Tenant’s Remediation, in which event Tenant shall complete Tenant’s Remediation as soon as reasonably practicable in accordance with
Environmental Laws, it being understood that Tenant’s Remediation shall not contain any requirement that Tenant remediate any contamination to levels or standards more stringent than those associated with the Property’s current office,
research and development, and laboratory uses. 
 (d) The provisions of this Section 17.5 shall survive the expiration or earlier
termination of this Lease. 

  
 PAGE 30 

 17.6 Disclosures. Prior to bringing any Hazardous Material into any part of the Property,
Tenant shall deliver to Landlord the following information with respect thereto: (a) a description of handling, storage, use and disposal procedures; (b) all plans or disclosures and/or emergency response plans which Tenant has prepared,
including without limitation Tenant’s Spill Response Plan, and all plans which Tenant is required to supply to any governmental agency or authority pursuant to any Environmental Laws; (c) copies of all Required Permits relating thereto;
and (d) other information reasonably requested by Landlord. 
 17.7 Removal. Tenant shall be responsible, at its sole cost and
expense, for Hazardous Material and other biohazard disposal services for the Premises. Such services shall be performed by contractors reasonably acceptable to Landlord and on a sufficient basis to ensure that the Premises are at all times kept
neat, clean and free of Hazardous Materials and biohazards except in appropriate, specially marked containers reasonably approved by Landlord. 

17.8 Landlord Representations and Indemnity. 

(a) Landlord represents to Tenant that, to the Best of Landlord’s Knowledge without inquiry, no Hazardous Materials exist in the Building
or the Property as of the Execution Date which are in violation of applicable Environmental Laws. Neither Landlord nor any Landlord Party shall introduce Hazardous Materials into the Building or the Property in violation of applicable Environmental
Laws as of the date of such introduction. Subject to the limitations on Landlord’s liability expressly set forth in this Lease, Landlord hereby agrees to indemnify, defend, and hold the Tenant Parties harmless from and against all Claims to the
extent arising from any breach by Landlord of its representations and agreements set forth in this Section 17.8(a). As used in this Section 17.8(a), “Best of Landlord’s Knowledge” means to the actual knowledge (without any
duty to investigate) of Landlord’s property manager, Edward Fontaine, or to the actual knowledge of Landlord’s asset managers, Shegun Holder and Nikko Politis. 

(b) If any Hazardous Materials are discovered in the Building or the Property which are not in compliance with applicable Environmental Laws
and which are not the responsibility of Tenant, then Landlord shall, when, if, and in the manner required by applicable Environmental Laws, remove or remediate such Hazardous Materials, unless such Hazardous Materials were introduced by Tenant or a
release thereof was caused by Tenant.

 18.2 Energy Conservation. Landlord may institute upon written notice to Tenant such
policies, programs and measures as may be necessary, required, or expedient for the conservation and/or preservation of energy or energy services (collectively, the “Conservation Program”), provided however, that the Conservation
Program does not, by reason of such policies, programs and measures, reduce the level of energy or energy services being provided to the Premises below the level of energy or energy services then being provided in comparable combination laboratory,
research and development and office buildings in the vicinity of the Premises, or as may be necessary or required to comply with Legal Requirements or standards or the other provisions of this Lease. Upon receipt of such notice, Tenant shall comply
with the Conservation Program. 
 18.3 Recycling. Upon written notice, Landlord may establish policies, programs and measures for the
recycling of paper, products, plastic, tin and other materials (a “Recycling Program”). Upon receipt of such notice, Tenant will comply with the Recycling Program at Tenant’s sole cost and expense.

reasonably required for its cure, then Tenant shall not be deemed to be in default if Tenant shall commence such cure within said thirty (30) day period and thereafter diligently prosecute such cure to completion, which completion shall occur
not later than ninety (90) days from the date of such written notice from Landlord; 
 (e) If Tenant enters into any written agreement

 PAGE 33 

 20.2 Remedies. Upon an Event of Default, Landlord may, by written notice to Tenant, elect
to terminate this Lease; and thereupon (and without prejudice to any remedies which might otherwise be available for arrears of Rent or preceding breach of covenant or agreement and without prejudice to Tenant’s liability for damages as

damages therefor, Landlord may, by lawful process, enter into and upon the Premises (or any part thereof in the name of the whole); repossess the same, as of its former estate; and expel Tenant and those claiming under Tenant. The words
“re-entry” and “re-enter” as used in this Lease are not restricted to their technical legal meanings. 
 20.3
Damages—Termination. 
 (a) Upon the termination of this Lease under the provisions of this Section 20, Tenant shall pay to
Landlord Rent up to the time of such termination, shall continue to be liable for any preceding breach of covenant, and in addition, shall pay to Landlord as damages, at the election of Landlord, either: 

(i) the amount (discounted to present value at the rate of five percent (5%) per annum by which, at the time of the termination of this
Lease (or at any time thereafter if Landlord shall have initially elected damages under Section 20.3(a)(ii) below), (x) the aggregate of Rent projected over the period commencing with such termination and ending on the Expiration Date,
exceeds (y) the aggregate projected rental value of the Premises for such period, taking into account a reasonable time period during which the Premises shall be unoccupied, plus all Reletting Costs (hereinafter defined); or 

(ii) amounts equal to Rent which would have been payable by Tenant had this Lease not been so terminated, payable upon the due dates therefor
specified herein following such termination and until the Expiration Date, provided, however, if Landlord shall re-let the Premises during such period, that Landlord shall credit Tenant with the net rents received by Landlord from such
re-letting, such net rents to be determined by first deducting from the gross rents as and when received by Landlord from such re-letting the expenses incurred or paid by Landlord in terminating this Lease, as well as the expenses of re-letting,
including altering and preparing the Premises for new tenants, brokers’ commissions, and all other expenses properly chargeable against the Premises and the rental therefrom (collectively, “Reletting Costs”), it being
understood that any such re-letting may be for a period equal to or shorter or longer than the remaining Term; and provided, further, that (x) in no event shall Tenant be entitled to receive any excess of such net rents over the sums
payable by Tenant to Landlord hereunder and (y) in no event shall Tenant be entitled in any suit for the collection of damages pursuant to this Section 20.3(a)(ii) to a credit in respect of any net rents from a re-letting except to the
extent that such net rents are actually received by Landlord prior to the commencement of such suit. If the Premises or any part thereof should be re-let in combination with other space, then proper apportionment on a square foot area basis shall be
made of the rent received from such re-letting and of the expenses of re-letting. 

  
 PAGE 34 

 (b) In calculating the amount due under Section 20.3(a)(i), above, there shall be included,
in addition to the Base Rent, all other considerations agreed to be paid or performed by Tenant, including without limitation Tenant’s Share of Expenses and Taxes, on the assumption that all such amounts and considerations would have increased
at the rate of five percent (5%) per annum for the balance of the full term hereby granted. 
 (c) Suit or suits for the recovery of
such damages, or any installments thereof, may be brought by Landlord from time to time at its election, and nothing contained herein shall be deemed to require Landlord to postpone suit until the date when the Term would have expired if it had not
been terminated hereunder. 
 (d) Nothing herein contained shall be construed as limiting or precluding the recovery by Landlord against
Tenant of any sums or damages to which, in addition to the damages particularly provided above, Landlord may lawfully be entitled by reason of any Event of Default hereunder. 

20.4 Landlord’s Self-Help; Fees and Expenses. If Tenant shall default in the performance of any covenant on Tenant’s part to
be performed in this Lease contained, including without limitation the obligation to maintain the Premises in the required condition pursuant to Section 10.1 above, and if Tenant fails to commence curing such default within ten (10) days
after written notice thereof from Landlord or thereafter fails to diligently prosecute such cure to completion, Landlord may, upon reasonable advance written notice, except that no notice shall be required in an emergency, immediately, or at any
time thereafter, perform the same for the account of Tenant. Tenant shall pay to Landlord upon demand therefor, any costs incurred by Landlord in connection therewith, together with interest at the Default Rate until paid in full. In addition,
Tenant shall pay all of Landlord’s costs and expenses, including without limitation reasonable attorneys’ fees, incurred (i) in enforcing any obligation of Tenant under this Lease or (ii) as a result of Landlord or any of the Landlord
Parties, without its fault, being made party to any litigation pending by or against any of the Tenant Parties. 
 20.5 Waiver of
Redemption, Statutory Notice and Grace Periods. Tenant does hereby waive and surrender all rights and privileges which it might have under or by reason of any present or future Legal Requirements to redeem the Premises or to have a continuance
of this Lease for the Term hereby demised after being dispossessed or ejected therefrom by process of law or under the terms of this Lease or after the termination of this Lease as herein provided. Except to the extent prohibited by Legal
Requirements, any statutory notice and grace periods provided to Tenant by law are hereby expressly waived by Tenant. 
 20.6
Landlord’s Remedies Not Exclusive. The specified remedies to which Landlord may resort hereunder are cumulative and are not intended to be exclusive of any remedies or means of redress to which Landlord may at any time be lawfully entitled,
and Landlord may invoke any remedy (including the remedy of specific performance) allowed at law or in equity as if specific remedies were not herein provided for. 

  
 PAGE 35 

 20.7 No Waiver. Landlord’s failure to seek redress for violation, or to insist upon
the strict performance, of any covenant or condition of this Lease, or any of the Rules and Regulations promulgated hereunder, shall not prevent a subsequent act, which would have originally constituted a violation, from having all the force and
effect of an original violation. The receipt by Landlord of Rent with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver of such breach. The failure of Landlord to enforce any of such Rules and Regulations against
Tenant and/or any other tenant in the Building shall not be deemed a waiver of any such Rules and Regulations. No provisions of this Lease shall be deemed to have been waived by either party unless such waiver be in writing signed by such party. No
payment by Tenant or receipt by Landlord of a lesser amount than the Rent herein stipulated shall be deemed to be other than on account of the stipulated Rent, nor shall any endorsement or statement on any check or any letter accompanying any check
or payment as Rent be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Rent or pursue any other remedy in this Lease provided. 

20.8 Restrictions on Tenant’s Rights. During the continuation of any Event of Default, Tenant shall not have the right to make, nor
to request Landlord’s consent or approval with respect to, any Alterations or Transfers. 
 20.9 Landlord Default.
Notwithstanding anything to the contrary contained in the Lease, Landlord shall in no event be in default in the performance of any of Landlord’s obligations under this Lease unless Landlord shall have failed to perform such obligations within
thirty (30) days (or such additional time as is reasonably required to correct any such default, provided Landlord commences cure within 30 days) after notice by Tenant to Landlord properly specifying wherein Landlord has failed to perform any
such obligation. Except as expressly set forth in this Lease, Tenant shall not have the right to terminate or cancel this Lease or to withhold rent or to set-off or deduct any claim or damages against rent as a result of any default by Landlord or
breach by Landlord of its covenants or any warranties or promises hereunder, except in the case of a wrongful eviction of Tenant from the Premises (constructive or actual) by Landlord, unless same continues after notice to Landlord thereof and an
opportunity for Landlord to cure the same as set forth above. In addition, Tenant shall not assert any right to deduct the cost of repairs or any monetary claim against Landlord from rent thereafter due and payable under this Lease. 

21. SURRENDER; ABANDONED PROPERTY; HOLD-OVER 

21.1 Surrender 
 (a) Upon
the expiration or earlier termination of the Term, Tenant shall (i) peaceably quit and surrender to Landlord the Premises (including without limitation all fixed electric, plumbing, heating and sprinkling systems, fixtures and outlets, vaults,
paneling, molding, shelving, radiator enclosures, cork, rubber, linoleum and composition floors, ventilating, silencing, air conditioning and cooling equipment therein) broom clean and in the same condition that Tenant is required to maintain the
Premises pursuant to Section 10.1; (ii) remove all of Tenant’s Property and Alterations made by Tenant (unless Landlord has expressly elected not to require Tenant to remove such Alterations in accordance with Section 11.1); and
(iii) repair any damages to the Premises or the Building caused by the installation or removal of Tenant’s Property and/or such Alterations. Tenant’s obligations under this Section 21.1(a) shall survive the expiration or earlier
termination of this Lease. 

  
 PAGE 36 

 (b) No act or thing done by Landlord during the Term shall be deemed an acceptance of a surrender
of the Premises, and no agreement to accept such surrender shall be valid, unless in writing signed by Landlord. Unless otherwise agreed by the parties in writing, no employee of Landlord or of Landlord’s agents shall have any power to accept
the keys of the Premises prior to the expiration or earlier termination of this Lease. The delivery of keys to any employee of Landlord or of Landlord’s agents shall not operate as a termination of this Lease or a surrender of the Premises.

 21.2 Abandoned Property. After the expiration or earlier termination hereof, if Tenant fails to remove any property from the
Building or the Premises which Tenant is obligated by the terms of this Lease to remove within five (5) business days after written notice from Landlord, such property (the “Abandoned Property”) shall be conclusively deemed to
have been abandoned, and may either be retained by Landlord as its property or sold or otherwise disposed of in such manner as Landlord may see fit. If any item of Abandoned Property shall be sold, Tenant hereby agrees that Landlord may receive and
retain the proceeds of such sale and apply the same, at its option, to the expenses of the sale, the cost of moving and storage, any damages to which Landlord may be entitled under Section 20 hereof or pursuant to law, and to any arrears of
Rent. 
 21.3 Holdover. If any of the Tenant Parties holds over (which term shall include, without limitation, the failure of Tenant
or any Tenant Party to perform all of its obligations under Section 21.1 above) after the end of the Term, Tenant shall be deemed a tenant-at-sufferance subject to the provisions of this Lease; provided that whether or not Landlord has
previously accepted payments of Rent from Tenant, (i) Tenant shall pay Base Rent at the Holdover Percentage (as hereinafter defined) of the Base Rent calculated on a daily basis at the highest rate payable during the Term, (ii) Tenant
shall continue to pay to Landlord all Additional Rent, and (iii) Tenant shall be liable for all damages, including without limitation lost business and consequential damages, incurred by Landlord as a result of such holding over beyond thirty
(30) days following the end of the Term or earlier termination hereof, Tenant hereby acknowledging that Landlord may need the Premises after the end of the Term for other tenants and that the damages which Landlord may suffer as the result of
Tenant’s holding over cannot be determined as of the Execution Date. Nothing contained herein shall grant Tenant the right to holdover after the expiration or earlier termination of the Term. The “Holdover Percentage” shall be
defined as (i) 150% with respect to first thirty (30) days of Tenant holding over and (ii) 200% with respect to any holdover by Tenant thereafter. 

21.4 Warranties. To the extent assignable, Tenant hereby assigns to Landlord any warranties in effect on the last day of the Term with
respect to any fixtures and Alterations installed in the Premises. Tenant shall provide Landlord with copies of any such warranties prior to the expiration of the Term (or, if the Lease is earlier terminated, within five (5) days thereafter).

  
 PAGE 37 

 22. MORTGAGEE RIGHTS 

22.1 Subordination. Tenant’s rights and interests under this Lease shall be (i) subject and subordinate to any ground lease,
overleases, mortgage, deed of trust, or similar instrument covering the Premises, the Building and/or the Land and to all advances, modifications, renewals, replacements, and extensions thereof (each of the foregoing, a “Mortgage”),
or (ii) if any Mortgagee elects, prior to the lien of any present or future Mortgage. Tenant further shall attorn to and recognize any successor landlord, whether through foreclosure or otherwise, as if the successor landlord were the
originally named landlord. The provisions of this Section 22.1 shall be self-operative and no further instrument shall be required to effect such subordination or attornment; however, Tenant agrees, within fifteen (15) days of request
therefor, to execute, acknowledge and deliver such instruments, confirming such subordination and attornment in such form as shall be requested by any such holder, consistent with the next following paragraph. 

Notwithstanding anything to the contrary contained herein, in order for this Section 22.1 to be effective Landlord shall obtain a
subordination, non-disturbance and attornment agreement from any future Mortgagees, and Tenant agrees that (i) any such agreement shall be on such Mortgagee’s customary form, which form may contain commercially reasonable limitations on
the liability of such Mortgagee, with such commercially reasonable revision as may be requested by Tenant, and (ii) Tenant shall pay any reasonable charges (including legal fees) required by such Mortgagee as a condition to entering into such
agreement. 
 22.2 Notices. Provided Tenant has been given an address for the Mortgagee(s), Tenant shall give each Mortgagee the same
written notices given to Landlord concurrently with the written notice to Landlord, and each Mortgagee shall have a reasonable opportunity thereafter to cure a Landlord default, and Mortgagee’s curing of any of Landlord’s default shall be
treated as performance by Landlord. 
 23. QUIET ENJOYMENT. 

Landlord covenants that so long as there is no Event of Default of Tenant, Tenant shall peaceably and quietly hold, occupy and enjoy the
Premises during the Term from and against the claims of all persons lawfully claiming by, through or under Landlord subject, nevertheless, to the covenants, agreements, terms, provisions and conditions of this Lease, any matters of record or of
which Tenant has knowledge and to any Mortgage to which this Lease is subject and subordinate, as hereinabove set forth. 
 24. NOTICES. 

Any notice, consent, request, bill, demand or statement hereunder (each, a “Notice”) by either party to the other party shall
be in writing and shall be deemed to have been duly given when either delivered by hand, first-class U.S. mail, certified or return receipt requested, or by nationally recognized overnight courier (in either case with evidence of delivery or refusal

 25. MISCELLANEOUS 

25.01 If any provision of this Lease or portion of such provision or the application thereof to any person or circumstance is for any
reason held invalid or unenforceable, the remainder of this Lease (or the remainder of such provision) and the application thereof to other persons or circumstances shall not be affected thereby. 

25.02 The captions are inserted only as a matter of convenience and for reference, and in no way define, limit or describe the scope of

warranty set forth in the immediately preceding sentence. Landlord shall be solely responsible for the payment of any brokerage commissions to Broker. 

25.04 This Lease, Lease Summary Sheet and Exhibits 1-8 attached hereto and incorporated herein contain the entire and only
agreement between the parties and any and all statements and representations, written and oral, including previous correspondence and agreements between the parties hereto, are merged herein. Tenant acknowledges that all representations and
statements upon which it relied in executing this Lease are contained herein and that Tenant in no way relied upon any other statements or representations, written or oral. This Lease may not be modified orally or in any manner other than by written

without limitation, costs incurred by Landlord in the review and approval of Tenant’s plans and specifications in connection with proposed Alterations to be made by Tenant to the Premises or in connection with requests by Tenant for

 PAGE40 

 25.09 

(a) Limitation on Landlord’s Liability. Tenant shall neither assert nor seek to enforce any claim against Landlord or any of the
Landlord Parties, or the assets of any of the Landlord Parties, for breach of this Lease or otherwise, other than against Landlord’s interest in the Building and in the uncollected rents, issues and profits thereof, and Tenant agrees to look
solely to such interest for the satisfaction of any liability of Landlord under this Lease. This Section 25.9 shall not limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord. Landlord and Tenant
specifically agree that in no event shall any officer, director, trustee, employee or representative of Landlord or any of the other Landlord Parties, ever be personally liable for any obligation under this Lease, nor shall Landlord or any of the
other Landlord Parties be liable for consequential or incidental damages or for lost profits whatsoever in connection with this Lease.  

(b) Limitation on Tenant’s Liability. Landlord and Tenant specifically agree that in no event shall any officer, director, trustee,
employee or representative of Tenant or any of the other Tenant Parties, ever be personally liable for any obligation under this Lease, nor shall Tenant or any of the other Tenant Parties be liable for consequential or incidental damages or for lost
profits whatsoever in connection with this Lease, provided however that nothing herein shall limit or affect any liability or obligation which Tenant may have under Section 21.3.  

25.10 The covenants, agreements, terms, provisions and conditions of this Lease shall bind and benefit the successors and assigns of the
parties hereto with the same effect as if mentioned in each instance where a party hereto is named or referred to, except that no violation of the provisions of Section 13 hereof shall operate to vest any rights in any successor or assignee of
Tenant. 
 25.11 Upon any sale, transfer or other disposition of the Building, Landlord shall be entirely freed and relieved from the
performance and observance thereafter of all covenants and obligations hereunder on the part of Landlord to be performed and observed, it being understood and agreed in such event (and it shall be deemed and construed as a covenant running with the
land) that the person succeeding to Landlord’s ownership of said reversionary interest shall thereupon and thereafter assume, and perform and observe, any and all of such covenants and obligations of Landlord, except as otherwise agreed in
writing. 
 25.12 Tenant shall not grant any interest whatsoever in any fixtures within the Premises or any item paid in whole or in
part by Landlord’s Contribution or by Landlord. 
 25.16 Tenant shall deliver to Landlord, within thirty (30) days after

accountant and certified by an officer of Tenant as being true and correct in all material respects. Any such financial information may be relied upon by any actual or potential lessor, purchaser, or mortgagee of the Property or any portion thereof.

 25.17 Executive Order No. 13224 on Terrorist Financing, effective September 24,
2001 (the “Executive Order”), and the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (Public Law 10756, the “Patriot Act”) prohibit certain
property transfers. Tenant hereby represents and warrants to Landlord (which representations and warranties shall be deemed to be continuing and re-made at all times during the Term) that neither Tenant nor to Tenant’s knowledge any
stockholder, manager, beneficiary, partner, or principal of Tenant is subject to the Executive Order, that none of them is listed on the United States Department of the Treasury Office of Foreign Assets Control (“OFAC”) list of
“Specially Designated Nationals and Blocked Persons” as modified from time to time, and that none of them is otherwise subject to the provisions of the Executive Order or the Patriot Act. The most current list of “Specially Designated
Nationals and Blocked Persons” can be found at http://www.treas.gov/offices/eotffc/ofac/sdn/index.html. Tenant shall from time to time, within ten days after request by Landlord, deliver to Landlord any certification or other evidence requested
from time to time by Landlord in its reasonable discretion, confirming Tenant’s compliance with these provisions. No assignment or subletting, other than a Related Party Transfer, shall be effective unless and until the assignee or subtenant
thereunder delivers to Landlord written confirmation of such party’s compliance with the provisions of this subsection, in form and content satisfactory to Landlord. If for any reason the representations and warranties set forth in this
subsection, or any certificate or other evidence of compliance delivered to Landlord hereunder, is untrue in any respect when made or delivered, or thereafter becomes untrue in any respect, then an Event of Default hereunder shall be deemed to occur
immediately, and there shall be no opportunity to cure. Tenant shall indemnify, defend with counsel reasonably acceptable to Landlord, and hold Landlord harmless from and against, any and all liabilities, losses claims, damages, penalties, fines,
and costs (including attorneys’ fees and costs) arising from or related to the breach of any of the foregoing representations, warranties, and duties of Tenant. The provisions of this subsection shall survive the expiration or earlier
termination of this Lease for the longest period permitted by law. 
 25.18 Tenant acknowledges and agrees that the terms of this
Lease are confidential. Disclosure of the terms hereof could adversely affect the ability of Landlord to negotiate other leases with respect to the Building and may impair Landlord’s relationship with other tenants of the Building. Tenant
agrees that Tenant and its partners, officers, directors and employees, shall not, and Tenant shall inform its brokers, and attorneys, if any, to not disclose the terms and conditions of this Lease to any other person or entity without the prior
written consent of Landlord which may be given or withheld by Landlord, in Landlord’s sole discretion, except as required for financial disclosures or securities filings, as required by the order of any court or public body with authority over
Tenant, or in connection with any litigation between Landlord and Tenant with respect this Lease. It is understood and agreed that damages alone would be an inadequate remedy for the breach of this provision by Tenant, and Landlord shall also have
the right to seek specific performance of this provision and to seek injunctive relief to prevent its breach or continued breach.

 EXHIBIT 3 

INITIAL ALTERATIONS 
 This
Exhibit is attached to and made a part of the Indenture of Lease (the “Lease”) by and between JAMESTOWN PREMIER 245 FIRST, LLC, a Delaware limited liability company (“Landlord”), and SAGE THERAPEUTICS,
INC., a Delaware corporation, a Delaware corporation (“Tenant”), for space in the Building located at 245 First Street, Cambridge, Massachusetts 02142. Capitalized terms used but not defined herein shall have the meanings given
in the Lease. 
 1. Performance of Initial Alterations. Tenant, following the delivery of the Premises by Landlord and the full and
final execution and delivery of the Lease to which this Exhibit is attached and security deposits required under such agreement, shall have the right to perform alterations and improvements in the Premises (the “Initial
Alterations”). Notwithstanding the foregoing, Tenant and its contractors shall not have the right to perform Initial Alterations in the Premises unless and until Tenant has complied with all of the terms and conditions of Section 11 of
the Lease, including, without limitation, approval by Landlord of the final plans for the Initial Alterations and the contractors to be retained by Tenant to perform such Initial Alterations. Tenant shall be responsible for all elements of the
design of Tenant’s plans (including, without limitation, compliance with law, functionality of design, the structural integrity of the design, the configuration of the Premises and the placement of Tenant’s furniture, appliances and
equipment), and Landlord’s approval of Tenant’s plans shall in no event relieve Tenant of the responsibility for such design. Landlord’s approval of Tenant’s plans for the Initial Alterations shall not be unreasonably withheld,
conditioned or delayed. Unless otherwise expressly agreed to by Landlord in writing, Tenant’s plans shall be consistent with the Building’s standards for leasehold improvements, which are attached to the Lease as Exhibit 8-2.
Landlord’s approval of the contractors to perform the Initial Alterations shall not be unreasonably withheld, conditioned or delayed. The parties agree that Landlord’s approval of the general contractor to perform the Initial Alterations
shall not be considered to be unreasonably withheld if any such general contractor (i) does not have trade references reasonably acceptable to Landlord, (ii) does not maintain insurance as required pursuant to the terms of this Lease,
(iii) does not have the creditworthiness to perform its obligations under the construction contract between such general contractor and Tenant, or (iv) is not licensed as a contractor in the state/municipality in which the Premises is
located. Tenant acknowledges the foregoing is not intended to be an exclusive list of the reasons why Landlord may reasonably withhold its consent to a general contractor. Tenant shall ensure that all contractors performing the Initial Alterations
include Landlord and such other parties as Landlord shall require as additional insureds on the insurance policies maintained by such contractors. 

2. Budget and Landlord’s Share. Promptly after Landlord approves Tenant’s plans for the Initial Alterations, Tenant shall
deliver to Landlord an itemized statement (the “Budget”) of the estimated hard and soft costs of the Initial Alterations (the “Estimated Cost”). Tenant shall, on a monthly basis, deliver to Landlord an updated
Budget of the Estimated Cost, based upon the information then available to Tenant. “Landlord’s Share” shall be defined as follows: (i) if the Estimated Cost, as set forth in the then current Budget is less than, or equal
to, the Maximum Amount of the Allowance, as hereinafter defined, then Landlord’s Share shall be 

  
 EXHIBIT 3, PAGE 1 

 
100%, and (ii) if the Estimated Cost, as set forth in the then current Budget, is greater than the Maximum Amount, then Landlord’s Share shall be equal to a fraction, the numerator of
which is the Maximum Amount, and the denominator of which is the Estimated Cost, as set forth in the then current Budget. 
 3. Definition
of Allowance. 
 (i) Allowance. Subject to the terms and conditions of this Exhibit, Landlord agrees to contribute
an amount (the “Allowance”) not to exceed of $594,150.00 (i.e., $30.00 per rentable square foot of the Premises) (the “Maximum Amount”) toward the cost of performing the Initial Alterations in preparation of
Tenant’s occupancy of the Premises, including, without limitation, the installation of data/telecom cabling. The Allowance may be used for the hard and soft costs (the “Permitted Costs”) incurred by Tenant in performing the
Initial Alterations. Tenant shall have the right to apply up to $198,050.00 of the Allowance (i.e., $10.00 per rentable square foot of the Premises) towards the costs incurred by Tenant in relocating to the Premises and purchasing furniture for the
Premises. 
 (ii) Test-Fit Allowance. In addition to providing the Allowance, Landlord shall contribute up to
$1,980.50 (i.e., $.10 per rentable square foot of the Premises) (the “Test-Fit Allowance”) towards the cost of the test-fit plan prepared by Tenant’s architect. Landlord shall, within thirty (30) days of receipt of paid
invoices from Tenant, pay the Test Fit Allowance to Tenant. 
 4. Payment Procedures. Landlord shall, subject to the provisions of
this Exhibit, pay Landlord’s Share of the amount requested by Tenant pursuant to each Requisition, as hereinafter defined, to Tenant or, at Landlord’s option, to the order of the general contractor that performs the Initial Alterations,
within thirty (30) days after Landlord’s receipt of such Requisition. In no event shall Landlord be required to: (i) pay more than the Maximum Amount of the Allowance towards Permitted Costs, (ii) disburse the Allowance more than
one time per month, or (iii) pay more than the Maximum Amount of the Allowance. Notwithstanding anything herein to the contrary, Landlord shall not be obligated to disburse any portion of the Allowance during the continuance of an uncured
monetary or material non-monetary default under the Lease; provided, however that if the Lease is in full force and effect and Tenant cures such default in accordance with the terms and conditions of the Lease, then Tenant shall have the right to
resubmit such declined Requisition, and Landlord shall pay any amounts properly due under such resubmitted Requisition, subject to the conditions and procedures set forth in this Exhibit 3. Landlord shall have the right, upon reasonable advance
notice to Tenant, to inspect Tenant’s books and records relating to each Requisition in order to verify the amount thereof. If Landlord fails timely to pay any portion of the Allowance properly due to Tenant pursuant to this Exhibit 3, and if
Landlord fails to cure such failure within ten (10) days after Landlord receives written notice of such failure from Tenant, then Tenant shall have the right to deduct such amount from the next installment(s) of Base Rent thereafter due under
the Lease. 

  
 EXHIBIT 3, PAGE 2 

 5. Requisition. A “Requisition” shall be defined as the following
documentation: (i) an application for payment and sworn statement of contractor substantially in the form of AIA Document G-702 covering all work for which disbursement is to be made to a date specified therein; (ii) a certification from
an AIA architect substantially in the form of the Architect’s Certificate for Payment which is located on AIA Document G702, Application and Certificate of Payment; (iii) Contractor’s, subcontractor’s and material supplier’s
waivers of liens which shall cover all Initial Alterations for which disbursement is being requested and all other statements and forms required for compliance with the mechanics’lien laws of the state in which the Premises is located, together
with all such invoices, contracts, or other supporting data as Landlord or Landlord’s Mortgagee may reasonably require; (iv) a cost breakdown for each trade or subcontractor performing the Initial Alterations; (v) plans and
specifications for the Initial Alterations; (vi) copies of all construction contracts for the Initial Alterations, together with copies of all change orders, if any; and (vii) a request to disburse from Tenant containing an approval by
Tenant of the work done and a good faith estimate of the cost to complete the Initial Alterations. In addition, the final Requisition (i.e., after the completion of the Initial Alterations, and prior to final disbursement of the Allowance) shall
include the following documentation: (1) general contractor and architect’s completion affidavits, (2) full and final waivers of lien from all contractors, subcontractors and material suppliers, (3) receipted bills covering all
labor and materials expended and used, (4) as-built plans of the Initial Alterations, and (5) the certification of Tenant and its architect that the Initial Alterations have been installed in a good and workmanlike manner in accordance
with the approved plans, and such approved plans were prepared (and such installation has been performed) in accordance with Legal Requirements, codes and ordinances. 

6. Outside Draw Date. If Tenant does not submit a request for payment of the entire Allowance to Landlord in accordance with the
provisions contained in this Exhibit by December 31, 2017 (the “Outside Draw Date”), any unused amount shall accrue to the sole benefit of Landlord, it being understood that Tenant shall not be entitled to any credit, abatement
or other concession in connection therewith. Tenant shall be responsible for all applicable state sales or use taxes, if any, payable in connection with the Initial Alterations and/or Allowance. 

7. Administration and Supervision Fee. Tenant shall pay an administration and supervision fee with respect to the Initial Alterations in
accordance with Section 11.6 of the Lease. 
 8. “As Is” Condition of Premises. Except as otherwise provided for in the
Lease, Tenant agrees to accept the Premises in its “as-is” condition and configuration, it being agreed that Landlord shall not be required to perform any work or, except as provided above with respect to the Allowance, incur any costs in
connection with the construction or demolition of any improvements in the Premises. This Exhibit shall not be deemed applicable to any additional space added to the Premises at any time or from time to time, whether by any options under the Lease or
otherwise, or to any portion of the original Premises or any additions to the Premises in the event of a renewal or extension of the original Term of the Lease, whether by any options under the Lease or otherwise, unless expressly so provided in the
Lease or any amendment or supplement to the Lease. 
 9. Miscellaneous. Tenant shall have the right to use the freight elevator and
loading dock on a twenty-four-(24)-hour basis at no additional charge.

EXPENSES AND TAXES 
 This
Exhibit is attached to and made a part of the Indenture of Lease (the “Lease”) by and between JAMESTOWN PREMIER 245 FIRST, LLC, a Delaware limited liability company (“Landlord”), and SAGE THERAPEUTICS,
INC., a Delaware corporation, a Delaware corporation (“Tenant”), for space in the Building located at 245 First Street, Cambridge, Massachusetts 02142. Capitalized terms used but not defined herein shall have the meanings given
in the Lease. 
 1. Payments. 
 1.01
Tenant shall pay (i) Tenant’s Building Pro Rata Share of the amount, if any, by which Expenses (defined below) for each calendar year during the Term exceed Expenses for the Base Year (the “Expense Excess”),
(ii) Tenant’s Common Area Pro Rata Share of the amount, if any, by which Taxes (defined below) for each calendar year during the Term exceed Taxes for the Base Year (the “Tax Excess”) and (iii) Tenant’s Common
Area Pro Rata Share of the amount, if any, by which Common Area Expenses (defined below) for the each calendar during the Term exceed Common Area Expenses for the Base Year (the “Common Area Expense Excess”). If Expenses, Taxes or
Common Area Expenses in any calendar year decrease below the amount of Expenses, Taxes or Common Area Expenses for the Base Year, Tenant’s Building Pro Rata Share of Expenses and Tenant’s Common Area Pro Rata Share of Taxes and Common Area
Expenses, as the case may be, for that calendar year shall be $0. Landlord shall provide Tenant with a good faith estimate of the Expense Excess, Tax Excess and Common Area Expense Excess for each calendar year during the Term. On or before the
first day of each month, Tenant shall pay to Landlord a monthly installment equal to one-twelfth of Tenant’s Building Pro Rata Share of Landlord’s estimate of the Expense Excess and one-twelfth of Tenant’s Common Area Pro Rata Share
of Landlord’s estimate of the Tax Excess and Common Area Expense Excess. If Landlord determines that its good faith estimate of the Expense Excess, the Tax Excess or the Common Area Expense Excess was incorrect by a material amount, Landlord
may provide Tenant with a revised estimate, provided that Landlord shall not provide a revised estimate more than twice per calendar year. After its receipt of the revised estimate, Tenant’s monthly payments shall be based upon the revised
estimate. If Landlord does not provide Tenant with an estimate of the Expense Excess, the Tax Excess or the Common Area Expense Excess by January 1 of a calendar year, Tenant shall continue to pay monthly installments based on the previous
year’s estimate(s) until Landlord provides Tenant with the new estimate. Upon delivery of the new estimate, an adjustment shall be made for any month for which Tenant paid monthly installments based on the previous year’s estimate. Tenant
shall pay Landlord the amount of any underpayment within 30 days after receipt of the new estimate. Any overpayment shall be refunded to Tenant within 30 days or credited against the next due future installment(s) of Additional Rent. 

1.02 As soon as is practical following the end of each calendar year, Landlord shall furnish Tenant with a statement of the actual Expenses and
Expense Excess, the actual Taxes and Tax Excess and the actual Common Area Expenses and Common Area Expense Excess for the prior calendar year. Landlord shall use reasonable efforts to furnish the statement of actual

  
 EXHIBIT 7, PAGE 1 

 
Expenses on or before June 1 of the calendar year immediately following the calendar year to which the statement applies. If the estimated Expense Excess, the estimated Tax Excess or the
estimated Common Area Expense Excess for the prior calendar year is more than the actual Expense Excess, actual Tax Excess and actual Common Area Expense Excess, as the case may be, for the prior calendar year, Landlord shall either provide Tenant
with a refund or apply any overpayment by Tenant against Additional Rent due or next becoming due, provided if the Term expires before the determination of the overpayment, Landlord shall refund any overpayment to Tenant after first deducting the
amount of Rent due. If the estimated Expense Excess, estimated Tax Excess or estimated Common Area Expense Excess for the prior calendar year is less than the actual Expense Excess, actual Tax Excess or actual Common Area Expense Excess, as the case
may be, for such prior year, Tenant shall pay Landlord, within 30 days after its receipt of the statement of Expenses, Taxes or Common Area Expenses, any underpayment for the prior calendar year. Any overpayment (less any amounts then due from
Tenant to Landlord) shall be refunded to Tenant within 30 days or credited against the next due future installment(s) of Additional Rent. 
 2.
Expenses. 
 2.01 “Expenses” means all costs and expenses incurred in each calendar year in connection with
operating, maintaining, repairing, and managing the Office Building, including the Common Areas located within the Office Building but excluding the Common Areas located in the Science Building and the shared Common Areas for both the Office
Building and the Science Building, and excluding the Common Area Expenses set forth in Section 2.02 below. Landlord agrees to act in a commercially reasonable manner in incurring Expenses, taking into consideration the class and quality of the
Office Building. “Expenses” shall include, but not be limited to: (a) all labor and labor related costs, including wages, salaries, bonuses, taxes, insurance, uniforms, training, retirement plans, pension plans and other employee
benefits; (b) management fees in an amount equal to 3% of the gross revenues from the Office Building and the Property; (c) the cost of equipping, staffing and operating an on-site and/or off-site management office for the Office Building,
provided if the management office services one or more other buildings or properties, the shared costs and expenses of equipping, staffing and operating such management office(s) shall be equitably prorated and apportioned between the Office
Building and the other buildings or properties; (d) accounting costs for the Office Building; (e) the cost of services; (f) rental and purchase cost of parts, supplies, tools and equipment; (g) insurance premiums and commercially
reasonable deductibles (Tenant hereby agreeing that, as of the Execution Date, a deductible not exceeding $100,000 is commercially reasonable); (h) electricity, gas and other utility costs attributable to the Office Building (exclusive of
electricity supplied to other leasable areas of the Building); (i) expenses of periodic routine testing to assure that the Premises and surrounding land are free of hazardous materials, agents or substances, and to assure compliance with codes,
regulations and Laws; and (j) the amortized cost of capital improvements (as distinguished from replacement parts or components installed in the ordinary course of business) made subsequent to the Base Year which are: (1) intended to
effect economies in the operation or maintenance of the Property, reduce current or future Expenses, enhance the safety or security of the Property or its occupants, (2) replacements or modifications of nonstructural items located in the Base
Building or Common Areas located within the Office Building that are required to keep the Base Building or Common Areas located within the Office Building in good condition, or (3) required under any

  
 EXHIBIT 7, PAGE 2 

 
Law that is enacted, or first interpreted to apply to the Property, after the date of the Lease. The cost of capital improvements shall be amortized by Landlord over the lesser of the Payback
Period (defined below) or the useful life of the capital improvement as reasonably determined by Landlord. The amortized cost of capital improvements may, at Landlord’s option, include actual or imputed interest at the rate that Landlord would
reasonably be required to pay to finance the cost of the capital improvement. “Payback Period” means the reasonably estimated period of time that it takes for the cost savings resulting from a capital improvement to equal the total cost of
the capital improvement. Landlord, by itself or through an affiliate, shall have the right to directly perform, provide and be compensated for any services under the Lease. If Landlord incurs Expenses for the Buildings or Property together with one
or more other buildings or properties, whether pursuant to a reciprocal easement agreement, common area agreement or otherwise, the shared costs and expenses shall be equitably prorated and apportioned between the Buildings and Property and the
other buildings or properties. 
 2.02 “Common Area Expenses” means all costs and expenses incurred in each calendar year in
connection with operating, maintaining, repairing and managing the shared Common Areas of the Buildings and the Property. Landlord agrees to act in commercially reasonable manner in incurring Common Area Expenses, taking into consideration the class
and quality of the Common Areas of the Buildings and the Property. Common Area Expenses include, without limitation: (a) security for the shared Common Areas of the Buildings; (b) electricity, gas and other utility costs with respect to
the shared Common Areas of the Buildings; (c) repairs to the shared Common Areas of the Buildings; and (d) the amortized cost of capital improvements (as distinguished from replacement parts or components installed in the ordinary course
of business) made subsequent to the Term Commencement Date which are: (1) intended to effect economies in the operation or maintenance of the Property, reduce current or future Common Area Expenses, enhance the safety or security of the
Property or its occupants, or enhance the environmental sustainability of the Property’s operations, (2) replacements or modifications of nonstructural items located in the Base Building or Common Areas of the Buildings that are required
to keep the Base Building or Common Areas of the Buildings in good condition, or (3) required under any Law that is enacted, or first interpreted to apply to the Property, after the date of the Lease. The cost of capital improvements shall be
amortized by Landlord over the lesser of the Payback Period (defined in Section 2.01 above) or the useful life of the capital improvement as reasonably determined by Landlord. Common Area Expenses shall not include any costs and expenses
incurred with respect to the Common Areas located in the Office Building and the Common Areas located in the Science Building. 
 2.03
Expenses and Common Area Expenses shall not include: the cost of capital improvements (except as set forth above); depreciation; principal, interest or any impound payments of mortgage and other non-operating debts of Landlord; the cost of repairs
or other work to the extent Landlord is reimbursed by insurance, other tenants or third parties or condemnation proceeds; costs in connection with leasing space in the Buildings, including brokerage commissions and marketing costs; lease
concessions, including rental abatements and construction allowances granted to specific tenants; costs incurred in connection with the sale, financing or refinancing of the Buildings; fines, interest and penalties incurred due to the late payment
of Taxes, Expenses or Common Area Expenses; organizational expenses associated with the creation and operation of the entity which constitutes Landlord; ground lease rental; 

  
 EXHIBIT 7, PAGE 3 

 
wages, salaries, fees, and fringe benefits (“Labor Costs”) paid to executive personnel above the level of senior property manager or officers or partners of Landlord, except that if
such individuals provide services directly related to the operation, maintenance or ownership of the Buildings which, if provided directly by a general manager/property manager or its general support staff, would normally be chargeable as an
operating expense of a comparable office Building, then an appropriate pro rata share of the Labor Costs of such individuals that is reflective of the extent to which such individuals are providing such services to the Building may be included in
Expenses; costs incurred by Landlord in connection with the correction of defects in design and original construction of the Building or Property; the cost or expense of any services or benefits provided generally to other tenants in the Building
and not provided or available to Tenant; sums (other than management fees, it being agreed that the management fees included in Expenses are as described in Section 2.01 above) paid to subsidiaries or other affiliates of Landlord for services
on or to the Property, Building and/or Premises, but only to the extent that the costs of such services exceed the competitive cost for such services rendered by persons or entities of similar skill, competence and experience; any general
administrative expenses, which costs would not be chargeable to operating expenses of the Building in accordance with generally accepted accounting principles, consistently applied; the cost of removing Hazardous Materials from the Buildings
(provided that the foregoing shall not preclude the inclusion of such costs with respect to: (i) materials which exist in the Buildings as of the Execution Date, which are not, as of the Execution Date, deemed to be Hazardous Materials, as a
matter of law, and which are subsequently deemed, as a matter of law, to be Hazardous Materials, and (ii) materials which are introduced to the Buildings after the Execution Date, which are not, as the date of such introduction, deemed to be
Hazardous Materials, as a matter of law, and which are subsequently deemed, as a matter of law, to be Hazardous Materials); attorneys’ fees incurred in connection with lease negotiations or disputes with individual tenants; the cost of
acquiring sculptures, paintings or other objects of art; or any penalties or damages that Landlord pays to Tenant under this Lease or to other tenants in the Buildings under their respective leases. 

2.04 If at any time during a calendar year the Office Building is not at least 95% occupied (or a service provided by Landlord to tenants of
the Office Building generally is not provided by Landlord to a tenant that provides such service itself, or any tenant of the Office Building is entitled to free rent, rent abatement or the like), Expenses and Common Area Expenses (but not Taxes)
shall, at Landlord’s option, be determined as if the Office Building had been 95% occupied (and all services provided by Landlord to tenants of the Office Building generally had been provided by Landlord to all tenants, and no tenant of the
Office Building had been entitled to free rent, rent abatement or the like) during that calendar year. If Expenses and Common Area Expenses for a calendar year are determined as provided in the prior sentence, Expenses and Common Area Expenses for
the Base Year shall also be determined in such manner. Notwithstanding the foregoing, Landlord may calculate the extrapolation of Expenses and Common Area Expenses under this Section based on 100% occupancy and service so long as such percentage is
used consistently for each year of the Term. The extrapolation of Expenses and Common Area Expenses under this Section shall be performed in accordance with the methodology specified by the Building Owners and Managers Association. 

  
 EXHIBIT 7, PAGE 4 

 3. “Taxes” shall mean: (a) all real property taxes and other assessments on the Office
Building, the Science Building and/or Property, including, but not limited to, gross receipts taxes, assessments for special improvement districts and building improvement districts, governmental charges, fees and assessments for police, fire,
traffic mitigation or other governmental service of purported benefit to the Property, taxes and assessments levied in substitution or supplementation in whole or in part of any such taxes and assessments and the Property’s share of any real
estate taxes and assessments under any reciprocal easement agreement, common area agreement or similar agreement as to the Property; (b) all personal property taxes for property that is owned by Landlord and used in connection with the
operation, maintenance and repair of the Property; and (c) all commercially reasonable costs and fees incurred in connection with seeking reductions in any tax liabilities described in (a) and (b), including, without limitation, any such
costs incurred by Landlord for compliance, review and appeal of tax liabilities. Without limitation, Taxes shall be determined without regard to any “green building” credit and shall not include any income, capital levy, transfer, capital
stock, gift, estate or inheritance tax or any interest or penalties incurred due to the late payment of Taxes. If a change in Taxes is obtained for any year of the Term during which Tenant paid Tenant’s Common Area Pro Rata Share of any Tax
Excess, then Taxes for that year will be retroactively adjusted and Landlord shall provide Tenant with a credit, if any, based on the adjustment. Likewise, if a change is obtained for Taxes for the Base Year, Taxes for the Base Year shall be
restated and the Tax Excess for all subsequent years shall be recomputed. Tenant shall pay Landlord the amount of Tenant’s Common Area Pro Rata Share of any such increase in the Tax Excess within 30 days after Tenant’s receipt of a
statement from Landlord. Any overpayment (less any amounts then due from Tenant to Landlord) shall be refunded to Tenant within 30 days or credited against the next due future installment(s) of Additional Rent. For the purpose of determining Taxes
for any given calendar year, the amount to be included in Taxes for such year shall be as follows: (1) with respect to any special assessment that is payable in installments, Taxes for such year shall include the amount of the installment (and
any interest paid or payable by Landlord) due and payable during such calendar year; and (2) with respect to all other real estate taxes, Taxes for such year shall, at Landlord’s election, include either the amount accrued, assessed or
otherwise imposed for such calendar year, provided that Landlord’s election shall be applied consistently throughout the Term of the Lease. 
 4.
Audit Rights. Within ninety (90) days after receiving Landlord’s statement of Expenses or Common Area Expenses as applicable (or, with respect to the Base Year Expenses or Base Year Common Area Expenses, within sixty (60) days
after receiving Landlord’s initial statement of Expenses or Common Area Expenses for the applicable Base Year, as the case may be) (each such period is referred to as the “Review Notice Period”), Tenant may give Landlord
written notice (“Review Notice”) that Tenant intends to review Landlord’s records of the Expenses and/or Common Area Expenses for the calendar year (or Base Year, as applicable) to which the statement applies, and within sixty
(60) days after sending the Review Notice to Landlord (such period is referred to as the “Request for Information Period”), Tenant shall send Landlord a written request identifying, with a reasonable degree of specificity, the
information that Tenant desires to review (the “Request for Information”). Within a reasonable time after Landlord’s receipt of a timely Request for Information and executed Audit Confidentiality Agreement (referenced below),
Landlord, as determined by Landlord, shall forward to Tenant, or make available for inspection on site at such location deemed reasonably appropriate by Landlord, such records (or copies thereof) relating to the amount of Expenses payable by Tenant
in the Office Building and (to the extent applicable) the Science Building for the applicable calendar year (or Base Year, as applicable) that are reasonably necessary for Tenant to conduct its review

  
 EXHIBIT 7, PAGE 5 

 
of the information appropriately identified in the Request for Information. Within one hundred twenty (120) days after any particular records are made available to Tenant (such period is
referred to as the “Objection Period”), Tenant shall have the right to give Landlord written notice (an “Objection Notice”) stating in reasonable detail any objection to Landlord’s statement of Expenses and/or
Common Area Expenses for that year which relates to the records that have been made available to Tenant. If Tenant provides Landlord with a timely Objection Notice, Landlord and Tenant shall work together in good faith to resolve any issues raised
in Tenant’s Objection Notice. If Landlord and Tenant determine that Expenses and/or Common Area Expenses for the calendar year are less than reported, Landlord shall provide Tenant with a credit against the next installment of Rent in the
amount of the overpayment by Tenant. Likewise, if Landlord and Tenant determine that Expenses and/or Common Area Expenses for the calendar year are greater than reported, Tenant shall pay Landlord the amount of any underpayment within thirty
(30) days. If Tenant fails to give Landlord an Objection Notice with respect to any records that have been made available to Tenant prior to expiration of the Objection Period applicable to the records which have been provided to Tenant, Tenant
shall be deemed to have approved Landlord’s statement of Expenses and/or Common Area Expenses with respect to the matters reflected in such records and shall be barred from raising any claims regarding the Expenses and/or Common Area Expenses
relating to such records for that year. If Tenant fails to provide Landlord with a Review Notice prior to expiration of the Review Notice Period or fails to provide Landlord with a Request for Information prior to expiration of the Request for
Information Period described above, Tenant shall be deemed to have approved Landlord’s statement of Expenses and/or Common Area Expenses and shall be barred from raising any claims regarding the Expenses and/or Common Area Expenses for that
year. 
 If Tenant retains an agent to review Landlord’s records, the agent must be with a CPA firm licensed to do business in the
state or commonwealth where the Property is located. Tenant shall be solely responsible for all costs, expenses and fees incurred for the audit, and the fees charged cannot be based in whole or in part on a contingency basis. The records and related
information obtained by Tenant shall be treated as confidential, and applicable only to the Office Building, by Tenant and its auditors, consultants and other parties reviewing such records on behalf of Tenant (collectively, “Tenant’s
Auditors”), and, prior to making any records available to Tenant or Tenant’s Auditors, Landlord may require Tenant and Tenant’s Auditors to each execute a reasonable confidentiality agreement (“Audit Confidentiality
Agreement”) in accordance with the foregoing. In no event shall Tenant be permitted to examine Landlord’s records or to dispute any statement of Expenses or Common Area Expenses unless Tenant has paid and continues to pay all Rent when
due, subject to any applicable notice, grace and cure periods.

4. Landlord may provide and maintain in the first floor (main lobby) of the Buildings an alphabetical directory board or other directory device
listing tenants and no other directory shall be permitted unless previously consented to by Landlord in writing. 
 5. Tenant shall not place

 Indoor Air Quality Guidelines 

PURPOSE 
 In today’s society, it is common for individuals
to spend upwards of 90% of their time in an indoor environment, whether at work or at home which makes planning for good IAQ an important consideration. Landlord Improvement Work (LIW) can adversely affect the indoor air quality (IAQ) in Landlord
spaces. The following guidelines will minimize these adverse effects by utilizing sound architectural, engineering and construction methods. Landlords are responsible for the design, engineering and work performed by their consultants and
contractors. During LIW it is important to isolate the construction area from all occupied and public areas of the building. All parties involved in designing, approving and constructing your space have an important role to play in keeping the
workplace comfortable and free of indoor pollutants such as dust, chemicals and volatile organic compounds that can originate from construction materials and building furnishings. Where feasible, occupants should be involved in decisions affecting
their work environment and be considered for temporary relocation away from construction. Please share these guidelines with your Architects, Engineers (A/E) and Contractors at the earliest phase of your planning. Contact the property team if you
have any questions about these guidelines. 
 CONTENTS 

Architect and Engineer’s Responsibilities 
 Contractor
Responsibilities, Pre-Construction Phase 
 Contractor Responsibilities, Construction Phase 

Completion Phase 
 ARCHITECT/ENGINEER’S RESPONSIBILITIES

 The A/E shall specify building materials, finishes, furniture and office equipment with products that have the lowest toxic-emitting potential as
compared with similar products. Architects should contact the property team for names of Indoor Air Quality Material Consultants for this information if needed. New carpet must have a green label certified by the Carpet and Rug Institute (CRI) and
be installed according to CRI installation guidelines. 
 The A/E shall avoid specifying materials containing chemicals listed as potentially carcinogenic,
mutagenic, teratogenic, neurotoxic or “sensitizing.” The following materials will not be allowed in new installations: 

  
 23 

	 	•	 	Materials containing more than trace (>0.1%) amounts of asbestos.Materials that containhalagenated hydrocarbon solvents (i.e., methylene chloride, tetrachloroethylene, trichloroethane). 

 

	 	•	 	HVAC components internally lined with permeable man-made mineral fiber products unless coated with “Tuffcoat” or other tough, resilient coating or mat surface that provides as smooth, non-shedding surface in
contact with the air stream. 

  

	 	•	 	Paints and sealants specified for “outdoor” and/or “marine” uses 

 The A/E shall review and
indicate on the project drawings the route for the contractor to enter and deliver materials to the construction site. The routes are known as passageways which are required to isolate the construction site from occupied spaces and common areas such
as, lobbies, elevators and other Landlord spaces. Where feasible, construction site passageways abutting Landlord occupied location shall incorporate single chamber “air locks” (two sets of doors or plastic strip doors at opposite ends of
an enclosed chamber or small room) into each construction site entrance. Plastic strip doors shall be a minimum 0.120” thick material with full overlap. Once installed, the air lock shall remain in place for the duration of the project or until
such a time as its presence restricts final completion of the renovations. Contractor passage routes should avoid or minimally intersect Landlord occupied areas of the building. 

The A/E shall stamp/certify the renovation drawings after checking that conflicts with the building’s mechanical, plumbing, electrical and sprinkler
systems are absent or minimized. Additional drawings shall be prepared showing any required modifications. The Engineer’s design must provide for proper air distribution and ventilation to all occupied areas with reconfigured partitioning
and/or HVAC systems. The Engineer’s design for all HVAC systems serving the project area must provide at least the minimum outside air ventilation rate, on the basis of actual occupancy, required by the building code, mechanical code or
ventilation code applicable at the time the facility was constructed. 
 The A/E shall document existing site conditions prior to the start of work. Before
finalizing the design, the Designer shall determine the HVAC system capacity (CFM and supply air temperature) available to the project area. This determination may be from record (“as-build”) drawings where available or field measurements
when record drawings are not available or their accuracy is in question. 
 CONTRACTOR RESPONSIBILITIES (Pre-Construction Phase) 

The Contractor will assist the property team, in providing pre-construction information sessions to the property team and adjacent Landlords during project
planning stages and/or at least 48 hours prior to project initiation. The information sessions should address the following: 
 Project scope and schedule:

  

	 	•	 	Anticipated construction impacts on indoor air quality (IAQ) or workplace conditions. 

  

	 	•	 	A strategy to minimize impact (e.g., engineering controls, material selection). 

  
 24 

	 	•	 	System to log, investigate and resolve occupant complaints related to construction impacts on IAQ or workplace conditions. 

Prior to starting work, the Contractor shall furnish copies of MSDS forms to the property team for all materials to be installed during the planned
renovations. 
 CONTRACTOR RESPONSIBILITIES (Construction Phase) 

Contractors shall construct and use only the construction site passageways indicated on the project drawings as approved by the property team. All persons and
materials passing to the construction site should be fully in the air lock and the door to the Landlord occupied areas closed before opening the construction site door (or flaps). At least one (set of air lock doors) (or flaps) must remain closed
throughout the renovation process. All persons leaving the site shall clean their feet on a contractor provided floor mat in the air lock prior to entering the Landlord occupied part of the building. The Contractor shall clean or replace the floor
mat regularly. 
 The property team is responsible for assuring that the contractor minimizes and contains the spread of odors and contaminants. Activities
that have potential to emit airborne contaminants must be coordinated with the property team. The Contractor shall: 
  

	 	•	 	Isolate all return air pathways from the construction area. 

  

	 	•	 	Cut and cap all supply air ducts serving the construction area except for temporary ducts supplying air to the construction area for temporary heat and air conditioning. 

 

	 	•	 	Install a temporary exhaust to outdoors sufficient to maintain the construction area at a pressure of –0.02” wc relative to adjacent occupied spaces. Temporary exhaust to outdoors may be through existing
building exhaust systems or through temporary louvers installed in place of windows or exterior doors. 

 The Contractor shall maintain air
tight duct work throughout the renovation process to avoid spreading construction related debris and/or airborne contaminants to the interior of any mechanical system component or to any construction free zone. Existing HVAC exhaust duct work that
is directly vented outside the building may remain operational during the renovation process. Upon completion of construction, the Contractor shall remove al installed seals and temporary ductwork. 

The Contractor shall install and maintain air-tight seals at all openings between landlord occupied areas of the building and the construction site (e.g.,
doorways, corridors, air plenums, chases, open conduits and duct work) throughout the course of the renovations activities. Upon completion of construction, the Contractor shall remove all installed barriers and seals. 

The property team will coordinate and direct the Contractor in assuring that the rest of the building outside the project area remains unaffected by the
project. In particular, HVAC systems altered for the purposes of controlling renovation site contaminants must continue to provide at least the minimum outside air ventilation rate to all occupied spaces. 

  
 25 

 The ventilation rate should be based on actual occupancy, required by the building code, mechanical code, or
ventilation code applicable at the time the facility was constructed. 
 The Contractor shall maintain the construction site a negative pressure (at least
–0.02” w.c.) relative to Landlord occupied spaces by operating temporary exhaust equipment at the renovation area. Temporary exhaust shall be by approved negative air machines with HEPA filtration. A minimum of one negative air machine
shall be provided for each 3000 square feet of construction space. The negative air machines shall be sized to complete 5 air changes per hour. The primary and pre filters must be changed daily and the HEPA filter must be replaced per
manufacturer’s specs or at a maximum of 800 run-hours. Activated carbon filters will be required when there is a possibility that work being performed will create odors that can cause a hazardous or uncomfortable work environment for other
building occupants. 
 Smoke eaters will be required anytime excessive smoke is present. The contractor will be responsible for notifying the property team
of any smoke created and will receive direction of what steps will be required to eliminate or reduce the smoke. 
 The Contractor shall use only
application-approved materials with the lowest content by volume of toxic or irritating chemicals. New carpet must have a green label certified by the Carpet and Rug Institute (CRI) and be installed according to CRI installation guidelines. The
Contractor shall avoid materials containing chemicals as potentially carcinogenic, mutagenic, teratogenic, neurotoxicor “sensitizing.” The following material will not be allowed in new installations: 

 

	 	•	 	Material containing greater than (0.1%) amounts of asbestos 

  

	 	•	 	Materials containing any halogenated hydrocarbon solvents (i.e., methylene chloride, tetrachloroethylene, trichloroethylene, tricholoroethane) 

 

	 	•	 	HVAC components internally lined with permeable man-made mineral fiber products unless coated with “Tuffcoat” or other tough, resilient coating or mat surface that provides a smooth, non-shedding surface in
contact with the air steam. 

  

	 	•	 	Paints and sealants specified for “outdoor” and/or “marine” uses 

 The Contractor shall
maintain the work area clean and free of open containers of paint, cleaners, chemicals, loose trash and garbage. The Contractor’s flammable and hazardous substances shall be stored to prevent spillage and in accordance with National Fire
Protection Association (NFPA) codes and OSHA regulations. 
 Electrically powered tools shall be utilized in place of combustion engine equipment. Unless
approved by product specifications, the Contractor shall not install wet or water damaged building materials. The Contractor shall protect stored materials from water and moisture prior to installation. The Contractor shall protect new building
assemblies from water damage following installation and inspect for signs of ineffective water and moisture control (e.g., condensation on pipes and ducts and roof and drain leaks) following installation 

  
 26 

 CONTRUCTION RESPONSIBILITIES (Completion Phase) 

The Contractor shall clean, or be responsible for the Landlord’s costs to clean all air plenums and mechanical system components determined to have
deteriorated as a result of the Contractor’s work activities. The original existing site conditions, as documented by the Contractor and accepted by the property team, shall be used to resolve conflicts related to building components requiring
decontamination. All cleaning shall meet the satisfaction of the property team. 
 All projects, including renovation, shall include air and, where
appropriate, water balancing in accordance with the Professional Engineer stamped/certified mechanical drawings. The Contractor must notify the Landlord’s representative 48 hours before the altered mechanical systems are ready for balancing.
The Air Balancing Contractor will be hired and coordinated by the property team. All Air Balancing reports must be presented and reviewed by the property team. 

Newly installed building materials, finishes, furniture and office equipment have a tendency to off-gas volatile organic compounds soon after they are
installed. The newly renovated space should be ventilated and exhausted directly to the outside for a period of 48-72 hours prior to occupancy.

 Building Riser Management 

Policy 
 Tenants/Vendors must provide a
written request a minimum of 48 hours in advance of any access to telephone and/or database building closets. The written request must include the following information: 
  

	 	•	 	A description of the work being performed. 

  

	 	•	 	A schedule of the work. If the work requires access to another tenant’s space, 72 hours advanced notice is required. Work may be required to occur outside of normal building hours, the presence of a security detail
and any freight/dock staffing requirements. 

  

	 	•	 	A list of all vendors involved which must provide a certificate of insurance as defined in the Definitions section. 

A property team member must respond in writing to confirm approval in order for work may proceed. 

Prior to the commencement of any work, a property team member will review the scope of the tenant contractor’s work, ask questions, and give direction on
how the contractor is to proceed. The contractor will review his completed work with a property team member to obtain approval on whether or not he has complied with building requirements including but not limited clean-up, fireproofing and overall
organization. 
 If a tenant is in possession of a key to a telephone or data closet, they are still required to notify and receive approval from the
property team per the guidelines established in this section. 
 When installing cabling between floors, in building riser rooms, and any location other
than above a suspended ceiling, a tenant contractor will use conduit in all locations. 
 When a tenant contractor installs phone lines or
“blocks” in the base building telephone closet, they will use conventional industry standards to properly and clearly identify those companies or individual users who are being served by the phone lines. 

All work of any kind performed or installed in the telephone or database-building closets will be identified. For cable installations in necessary conduits
between floors, the cable or conduit will be tagged on every floor of such vertical installation. 
 When conduit is installed and extended laterally from a
base building closet to tenant suites and the conduit penetrates the wall (i.e. drywall) of a closet, a tenant contractor must use the following product (or equivalent product as approved by property engineers) to properly “fire safe” the
wall penetration with an approved fire proofing with a minimum two hour rating or as code dictates. 

  
 30 

 Horizontal cable runs in a base building closet will also be installed in conduit and secured in an organized
fashion with the use of D-rings. If there are no existing available D-rings in the closet then the tenant contractor must install them at his expense 
 The
contractor will be responsible for marking identification information on every tag installed. The following identification information must be printed on every tag: 

Name of tenant being served 
 Suite(s) number being served 

Identify extent of cable run (floor x to floor y) 
 Type of cable
material construction 
 Date of installation 
 Sample Tag:

 Altheimer & Gray

 Suite 3800 
 Floors 35-38 

Cat. 5 
 January 5, 2012

 Exhibit “A” Certificates of 

Insurance 
 Certificates of Insurance

 Jamestown requires all service contractors to carry insurance. Property Management collects certificates of insurance, which contain information about
the Vendor’s insurance. 
 This insurance must meet certain minimum requirements and name Jamestown Premier 245 First LLC and other related parties as
additional insured’s (see separate insurance requirements). 
 Service Contractor Certificates 

The specific insurance requirements for a particular service contractor are those written into their contract with the building owner/manager or tenant, and
these may differ from the guidelines listed below. When determining whether or not a certificate shows coverage that meets the actual requirements for a particular service contractor, always refer to the contract wording. 

For service contractors, the standard operating procedures require having a certificate of insurance naming the owner and manager of the building as
additional insured, and having a signed contract/service agreement in place listing the insurance requirements and having an indemnification section.

payment of interest following the issue date of such further Securities). Such further Securities may be consolidated and form a single series with the Securities of such series and have the same terms as to status, redemption or otherwise as the

 Section 2.04 Authentication and Delivery of Securities. The Issuer may deliver
Securities of any series executed by the Issuer to the Trustee for authentication together with the applicable documents referred to below in this Section, and the Trustee shall thereupon authenticate and deliver such Securities to or upon the order
of the Issuer (contained in the Issuer Order referred to below in this Section) or pursuant to such procedures acceptable to the Trustee and to such recipients as may be specified from time to time by an Issuer Order. If provided for in such
procedures, such Issuer Order may authorize authentication and delivery pursuant to oral instructions from the Issuer or its duly authorized agent, which instructions shall be promptly confirmed in writing. In authenticating such Securities and
accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 6.01) shall be fully protected in relying upon: 

(a) an Issuer Order requesting such authentication and setting forth delivery instructions if the Securities are not to be
delivered to the Issuer; 
 (b) any Board Resolution, Officer’s Certificate and/or executed supplemental indenture
referred to in Sections 2.01 and 2.03 by or pursuant to which the forms and terms of the Securities were established; 
 (c)
an Officer’s Certificate setting forth the form or forms and terms of the Securities stating that the form or forms and terms of the Securities have been established pursuant to Sections 2.01 and 2.03 and comply with this Indenture, and
covering such other matters as the Trustee may reasonably request; and 
 (d) an Opinion of Counsel to the effect that: 

(i) the form or forms and terms of such Securities have been established pursuant to Sections 2.01 and 2.03 and comply with
this Indenture, 
 (ii) the authentication and delivery of such Securities by the Trustee are authorized under the provisions
of this Indenture, 
 (iii) such Securities when authenticated and delivered by the Trustee and issued by the Issuer in the
manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and binding obligations of the Issuer, and 

(iv) all laws and requirements in respect of the execution and delivery by the Issuer of the Securities have been complied
with, 
 and covering such other matters as the Trustee may reasonably request. 

The Trustee shall have the right to decline to authenticate and deliver any Securities under this Section if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken by the Issuer or if the Trustee in good faith by its board of directors or board of trustees, executive committee, or a trust committee of directors or trustees or Responsible Officers
shall determine that such action would expose the Trustee to personal liability to existing Holders or would affect the Trustee’s own rights, duties or immunities under the Securities, this Indenture or otherwise. 

The Issuer shall execute and the Trustee shall, in accordance with this Section with respect to the Securities of a series, authenticate and
deliver one or more Global Securities that (i) shall represent and shall be denominated in an amount equal to the aggregate principal amount of all of the Securities of such series issued and not yet cancelled, (ii) shall be registered in
the name of the Depositary for such Global Security or Securities or the nominee of such Depositary, (iii) shall be delivered by the Trustee to such Depositary or pursuant to such Depositary’s instructions and (iv) shall bear a legend
substantially to the following effect: 

  
 8 

 “Unless and until it is exchanged in whole or in part for Securities in
definitive registered form, this Security may not be transferred except as a whole by the Depositary to the nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or
any such nominee to a successor Depositary or a nominee of such successor Depositary.” 
 Each Depositary designated pursuant to this
Section must, at the time of its designation and at all times while it serves as Depositary, be a clearing agency registered under the Securities Exchange Act of 1934 and any other applicable statute or regulation. 

Section 2.05 Execution of Securities. The Securities shall be signed on behalf of the Issuer by the chairman of the Board
of Directors, the president, the chief financial officer, the treasurer or the secretary of the Issuer. Such signatures may be the manual or facsimile signatures of the present or any future such officers. Typographical and other minor errors or
defects in any such reproduction of any such signature shall not affect the validity or enforceability of any Security that has been duly authenticated and delivered by the Trustee. 

In case any officer of the Issuer who shall have signed any of the Securities shall cease to be such officer before the Security so signed
shall be authenticated and delivered by the Trustee or disposed of by the Issuer, such Security nevertheless may be authenticated and delivered or disposed of as though the person who signed such Security had not ceased to be such officer of the
Issuer; and any Security may be signed on behalf of the Issuer by such persons as, at the actual date of the execution of such Security, shall be the proper officers of the Issuer, although at the date of the execution and delivery of this Indenture
any such person was not such an officer. 
 Section 2.06 Certificate of Authentication. Only such Securities as shall
bear thereon a certificate of authentication substantially in the form hereinbefore recited, executed by the Trustee by the manual signature of one of its authorized officers, shall be entitled to the benefits of this Indenture or be valid or
obligatory for any purpose. The execution of such certificate by the Trustee upon any Security executed by the Issuer shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the
Holder is entitled to the benefits of this Indenture. 
 Section 2.07 Denomination and Date of Securities; Payments of
Interest. The Securities of each series shall be issuable in denominations established as contemplated by Section 2.03 or, if not so established, in denominations of $1,000 and any integral multiple thereof. The Securities of each
series shall be numbered, lettered or otherwise distinguished in such manner or in accordance with such plan as the officers of the Issuer executing the same may determine with the approval of the Trustee, as evidenced by the execution and
authentication thereof. Unless otherwise indicated in a Board Resolution, Officer’s Certificate or supplemental indenture for a particular series, interest will be calculated on the basis of a 360-day year of twelve 30-day months. 

Each Security shall be dated the date of its authentication. The Securities of each series shall bear interest, if any, from the date, and
such interest shall be payable on the dates, established as contemplated by Section 2.03. 
 The Person in whose name any Security of
any series is registered at the close of business on any record date applicable to a particular series with respect to any interest payment date for such series shall be entitled to receive the interest, if any, payable on such interest payment date
notwithstanding any transfer, exchange or conversion of such Security subsequent to the record date and prior to such interest payment date, except if and to the extent the Issuer shall default in the payment of the interest due on such interest
payment date for such series, in which case such defaulted interest shall be paid to the Persons in whose names Outstanding Securities for such series are registered at the close of business on a subsequent record date (which shall be not less than
five Business Days prior to the date of payment of such defaulted interest) established by notice given by mail by or on behalf of the Issuer to the Holders of Securities not less than 15 days preceding such subsequent record date. The term
“record date” as used with respect to any interest payment date (except a date for payment of defaulted interest) for the Securities of any series shall mean the date specified as such in the terms of the Securities of such series
established as contemplated by Section 2.03, or, if no such date is so established, if such interest payment date is the first day of a calendar month, the 15th day of the immediately preceding calendar month or, if such interest payment date
is the 15th day of a calendar month, the first day of such calendar month, whether or not such record date is a Business Day. 

  
 9 

 Section 2.08 Registration, Transfer and Exchange. The Issuer will keep at each
office or agency to be maintained for the purpose as provided in Section 3.02 for each series of Securities a register or registers in which, subject to such reasonable regulations as it may prescribe, it will provide for the registration of
Securities of such series and the registration of transfer of Securities of such series. Such register shall be in written form in the English language or in any other form capable of being converted into such form within a reasonable time. At all
reasonable times such register or registers shall be open for inspection by the Trustee. 
 Upon due presentation for registration of
transfer of any Security of any series at any such office or agency to be maintained for the purpose as provided in Section 3.02, the Issuer shall execute and the Trustee shall authenticate and deliver in the name of the transferee or
transferees a new Security or Securities of the same series, maturity date, interest rate and original issue date in authorized denominations for a like aggregate principal amount. 

At the option of the Holder thereof, Securities of any series (except a Global Security) may be exchanged for a Security or Securities of such
series having authorized denominations and an equal aggregate principal amount, upon surrender of such Securities to be exchanged at the agency of the Issuer that shall be maintained for such purpose in accordance with Section 3.02 and upon
payment, if the Issuer shall so require, of the charges hereinafter provided. Whenever any Securities are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive. All Securities surrendered upon any exchange or transfer provided for in this Indenture shall be promptly cancelled and disposed of by the Trustee and the Trustee will deliver a certificate of disposition thereof
to the Issuer. 
 All Securities presented for registration of transfer, exchange, redemption or payment shall (if so required by the Issuer
or the Trustee) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Issuer and the Trustee duly executed by, the Holder or his or her attorney duly authorized in writing. 

The Issuer may require payment of a sum sufficient to cover any stamp or other tax or other governmental charge that may be imposed in
connection with any exchange or registration of transfer of Securities. No service charge shall be made for any such transaction. 
 The
Issuer shall not be required to exchange or register a transfer of (a) any Securities of any series for a period of 15 days immediately preceding the first mailing of notice of redemption of Securities of such series to be redeemed or
(b) any Securities selected, called or for which notice of redemption has been provided to the Trustee, in whole or in part, except, in the case of any Security to be redeemed in part, the portion thereof not so to be redeemed. 

  
 10 

 Notwithstanding any other provision of this Section 2.08, unless and until it is exchanged
in whole or in part for Securities in definitive registered form, a Global Security representing all or a portion of the Securities of a series may not be transferred except as a whole by the Depositary for such series to a nominee of such
Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor Depositary. 

If at any time the Depositary for the Securities of a series notifies the Issuer that it is unwilling or unable to continue as Depositary for
the Securities of such series or if at any time the Depositary for the Securities of a series shall no longer be eligible under Section 2.04, the Issuer shall appoint a successor Depositary with respect to the Securities of such series. If a
successor Depositary for the Securities of such series is not appointed by the Issuer within 90 days after the Issuer receives such notice or becomes aware of such ineligibility, the Issuer’s determination pursuant to Section 2.03 that the
Securities of such series be represented by a Global Security shall no longer be effective and the Issuer will execute, and the Trustee, upon receipt of an Officer’s Certificate for the authentication and delivery of definitive Securities of
such series, will authenticate and deliver, Securities of such series in definitive registered form, in any authorized denominations, in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing
the Securities of such series, in exchange for such Global Security or Securities. 
 The Issuer may at any time and in its sole discretion
determine that the Securities of any series issued in the form of one or more Global Securities shall no longer be represented by a Global Security or Securities. In such event the Issuer will execute, and the Trustee, upon receipt of an
Officer’s Certificate for the authentication and delivery of definitive Securities of such series, will authenticate and deliver, Securities of such series in definitive registered form, in any authorized denominations, in an aggregate
principal amount equal to the principal amount of the Global Security or Securities representing such series, in exchange for such Global Security or Securities. 

The Depositary for such Global Security may surrender such Global Security in exchange in whole or in part for Securities of the same series
in definitive registered form in accordance with the two preceding paragraphs or on such other terms as are acceptable to the Issuer and such Depositary. Thereupon, the Issuer shall execute, and the Trustee shall authenticate and deliver, without
service charge, 
 (i) to the Person specified by such Depositary a new Security or Securities of the same series, of any
authorized denominations as requested by such Person, in an aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Global Security; and 

(ii) to such Depositary a new Global Security in a denomination equal to the difference, if any, between the principal amount
of the surrendered Global Security and the aggregate principal amount of Securities authenticated and delivered pursuant to clause (i) above. 

Upon the exchange of a Global Security for Securities in definitive registered form, in authorized denominations, such Global Security shall
be cancelled by the Trustee. Securities in definitive registered form issued in exchange for a Global Security pursuant to this Section 2.08 shall be registered in such names and in such authorized denominations as the Depositary for such
Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to or as directed by the Persons in whose names such Securities are so registered.

  
 11 

 All Securities issued upon any transfer or exchange of Securities shall be valid obligations of
the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. 

Section 2.09 Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In case any temporary or definitive Security shall
become mutilated, defaced or be destroyed, lost or stolen, the Issuer in its discretion may execute, and upon the written request of any officer of the Issuer, the Trustee shall authenticate and deliver a new Security of the same series, maturity
date, interest rate and original issue date, bearing a number or other distinguishing symbol not contemporaneously outstanding, in exchange and substitution for the mutilated or defaced Security, or in lieu of and substitution for the Security so
destroyed, lost or stolen. In every case the applicant for a substitute Security shall furnish to the Issuer and to the Trustee and any agent of the Issuer or the Trustee such security or indemnity as may be required by them to indemnify and defend
and to save each of them harmless and, in every case of destruction, loss or theft, evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof and in the case of mutilation or defacement shall
surrender the Security to the Trustee. 
 Upon the issuance of any substitute Security, the Issuer may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. In case any Security which has matured or is about to
mature or has been called for redemption in full, or is being surrendered for conversion in full, shall become mutilated or defaced or be destroyed, lost or stolen, the Issuer may, instead of issuing a substitute Security (with the Holder’s
consent, in the case of convertible Securities), pay or authorize the payment of the same or convert, or authorize conversion of the same (without surrender thereof except in the case of a mutilated or defaced Security), if the applicant for such
payment shall furnish to the Issuer and to the Trustee and any agent of the Issuer or the Trustee such security or indemnity as any of them may require to save each of them harmless, and, in every case of destruction, loss or theft, the applicant
shall also furnish to the Issuer and the Trustee and any agent of the Issuer or the Trustee evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof. 

Every substitute Security of any series issued pursuant to the provisions of this Section by virtue of the fact that any such Security is
destroyed, lost or stolen shall constitute an additional contractual obligation of the Issuer, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone and shall be entitled to all the benefits of (but shall
be subject to all the limitations of rights set forth in) this Indenture equally and proportionately with any and all other Securities of such series duly authenticated and delivered hereunder. All Securities shall be held and owned upon the express
condition that, to the extent permitted by law, the foregoing provisions are exclusive with respect to the replacement or payment or conversion of mutilated, defaced or destroyed, lost or stolen Securities and shall preclude any and all other rights
or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender. 

Section 2.10 Cancellation of Securities; Destruction Thereof. All Securities surrendered for exchange for Securities of the
same series or for payment, redemption, registration of transfer, conversion or for credit against any payment in respect of a sinking or analogous fund, if surrendered to the Issuer or any agent of the Issuer or the Trustee, shall be delivered to
the Trustee for cancellation or, if surrendered to the Trustee, shall be cancelled by it; and no Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of
cancelled Securities held by it and deliver a certificate of disposition to the Issuer. If the Issuer shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the Debt represented by such Securities
unless and until the same are delivered to the Trustee for cancellation. 

  
 12 

 Section 2.11 Temporary Securities. Pending the preparation of definitive
Securities for any series, the Issuer may execute and the Trustee shall authenticate and deliver temporary Securities for such series (printed, lithographed, typewritten or otherwise reproduced, in each case in form satisfactory to the Trustee).
Temporary Securities of any series shall be issuable in any authorized denomination, and substantially in the form of the definitive Securities of such series but with such omissions, insertions and variations as may be appropriate for temporary
Securities, all as may be determined by the Issuer with the concurrence of the Trustee as evidenced by the execution and authentication thereof. Temporary Securities may contain such reference to any provisions of this Indenture as may be
appropriate. Every temporary Security shall be executed by the Issuer and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Securities. Without unreasonable delay
the Issuer shall execute and shall furnish definitive Securities of such series and thereupon temporary Securities of such series may be surrendered in exchange therefor without charge at each office or agency to be maintained by the Issuer for that
purpose pursuant to Section 3.02 and the Trustee shall authenticate and deliver in exchange for such temporary Securities of such series an equal aggregate principal amount of definitive Securities of the same series having authorized
denominations. Until so exchanged, the temporary Securities of any series shall be entitled to the same benefits under this Indenture as definitive Securities of such series, unless the benefits of the temporary Securities are limited pursuant to
Section 2.03. 
 ARTICLE 3 

COVENANTS OF THE ISSUER 

Section 3.01 Payment of Principal and Interest. The Issuer covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay or cause to be paid the principal of, and interest on, each of the Securities of such series (together with any additional amounts payable pursuant to the terms of such Securities) at the place or
places, at the respective times and in the manner provided in such Securities and in this Indenture. The interest on Securities (together with any additional amounts payable pursuant to the terms of such Securities) shall be payable only to or upon
the written order of the Holders thereof and at the option of the Issuer may be paid by mailing checks for such interest payable to or upon the written order of such Holders at their last addresses as they appear on the Security register of the
Issuer. 
 Section 3.02 Offices for Payments, Etc. The Issuer will maintain (i) in St. Louis, Missouri, an agency
where the Securities of each series may be presented for payment, an agency where the Securities of each series may be presented for exchange and conversion, if applicable, as provided in this Indenture and an agency where the Securities of each
series may be presented for registration of transfer as in this Indenture provided and (ii) such further agencies in such places as may be determined for the Securities of such series pursuant to Section 2.03. 

The Issuer will maintain in St. Louis, Missouri, an agency where notices and demands to or upon the Issuer in respect of the Securities of any
series or this Indenture may be served. 
 The Issuer will give to the Trustee written notice of the location of each such agency and of any
change of location thereof. In case the Issuer shall fail to maintain any agency required by this Section to be located in St. Louis, Missouri, or shall fail to give such notice of the location or of any change in the location of any of the above
agencies, presentations and demands may be made and notices may be served at the Corporate Trust Office of the Trustee. 

  
 13 

 The Issuer may from time to time designate one or more additional agencies where the Securities
of a series may be presented for payment, where the Securities of that series may be presented for exchange or conversion, if applicable, as provided in this Indenture and pursuant to Section 2.03 and where the Securities of that series may be
presented for registration of transfer as in this Indenture provided, and the Issuer may from time to time rescind any such designation, as the Issuer may deem desirable or expedient; provided, however, that no such designation or rescission shall
in any manner relieve the Issuer of its obligation to maintain the agencies provided for in this Section. The Issuer will give to the Trustee prompt written notice of any such designation or rescission thereof. 

Section 3.03 Appointment to Fill a Vacancy in Office of Trustee. The Issuer, whenever necessary to avoid or fill a vacancy
in the office of Trustee, will appoint, in the manner provided in Section 6.10, a Trustee, so that there shall at all times be a Trustee with respect to each series of Securities hereunder. 

Section 3.04 Paying Agents. Whenever the Issuer shall appoint a paying agent other than the Trustee with respect to the
Securities of any series, it will cause such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section, 

(a) that it will hold all sums received by it as such agent for the payment of the principal of or interest on the Securities
of such series (whether such sums have been paid to it by the Issuer or by any other obligor on the Securities of such series) in trust for the benefit of the Holders of the Securities of such series or of the Trustee, 

(b) that it will give the Trustee notice of any failure by the Issuer (or by any other obligor on the Securities of such
series) to make any payment of the principal of or interest on the Securities of such series when the same shall be due and payable, and 

(c) that at any time during the continuance of any such failure, upon the written request of the Trustee, it will forthwith
pay to the Trustee all sums so held in trust by such paying agent. 
 The Issuer will, on or prior to each due date of the principal of or
interest on the Securities of such series, deposit with the paying agent a sum sufficient to pay such principal or interest so becoming due, and (unless such paying agent is the Trustee) the Issuer will promptly notify the Trustee of any failure to
take such action. 
 If the Issuer shall act as its own paying agent with respect to the Securities of any series, it will, on or before
each due date of the principal of or interest on the Securities of such series, set aside, segregate and hold in trust for the benefit of the Holders of the Securities of such series a sum sufficient to pay such principal or interest so becoming
due. The Issuer will promptly notify the Trustee of any failure to take such action. 
 Anything in this Section to the contrary
notwithstanding, but subject to Section 10.01, the Issuer may at any time, for the purpose of obtaining a satisfaction and discharge with respect to one or more or all series of Securities hereunder, or for any other reason, pay or cause to be
paid to the Trustee all sums held in trust for any such series by the Issuer or any paying agent hereunder, as required by this Section, such sums to be held by the Trustee upon the trusts herein contained.

 ARTICLE 5 

REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT 

Section 5.01 Event of Default Defined; Acceleration of Maturity; Waiver of Default. “Event of Default”, with
respect to Securities of any series wherever used herein, means each one of the following events which shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): 

(a) default in the payment of any installment of interest upon any of the Securities of such series as and when the same shall
become due and payable, and continuance of such default for a period of 90 days (or such other period as may be established for the Securities of such series as contemplated by Section 2.03); or 

(b) default in the payment of all or any part of the principal on any of the Securities of such series as and when the same
shall become due and payable either at maturity, upon redemption, by declaration or otherwise (and, if established for the Securities of such series as contemplated by Section 2.03, the continuance of such default for a specified period); or

 (c) default in the performance, or breach, of any covenant or agreement of the Issuer in respect of the Securities of such
series (other than a covenant or agreement in respect of the Securities of such series a default in the performance or breach of which is elsewhere in this Section specifically dealt with), and continuance of such default or breach for a period of
90 days after there has been given, by registered or certified mail, to the Issuer by the Trustee or to the Issuer and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of all series affected thereby, a
written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or 

(d) a court having jurisdiction in the premises shall enter a decree or order for relief in respect of the Issuer in an
involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Issuer or for all or
substantially all of its property and assets or ordering the winding up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect for a period of 90 consecutive days; or 

(e) the Issuer shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or
hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar
official) of the Issuer or for any substantial part of its property and assets, or make any general assignment for the benefit of creditors; or 

(f) any other Event of Default provided for in such series of Securities. 

If an Event of Default described in clauses (a), (b), (c) or (f) occurs and is continuing, then, and in each and every such case,
unless the principal of all of the Securities of such series shall have already become due and payable, either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Securities of such series then Outstanding hereunder
(each such series voting as a separate class) by notice in writing to the Issuer (and also to the Trustee if given by Securityholders), may declare the entire principal (or, if the Securities of such series are Original Issue Discount Securities,
such portion of the principal amount as may be specified in the terms of such series) of all Securities of such series and the interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration the same shall become
immediately due and payable. If an Event of Default described in clauses (d) or (e) occurs and is continuing, then and in each and every such case, the entire principal (or, if any Securities are Original Issue Discount Securities, such
portion of the principal as may be specified in the terms thereof) of all the Securities then Outstanding and interest accrued thereon, if any, shall become immediately due and payable. 

  
 16 

 The foregoing provisions, however, are subject to the condition that if, at any time after the
principal of the Securities of any series shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Issuer shall pay or shall
deposit with the Trustee a sum sufficient to pay all matured installments of interest upon all the Securities of such series and the principal of any and all Securities of such series which shall have become due otherwise than by acceleration (with
interest upon such principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest, at the same rate as the rate of interest specified in the Securities of such series to the date
of such payment or deposit) and such amount as shall be sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee except as a
result of negligence or bad faith, and if any and all Events of Default under the Indenture with respect to such series, other than the non-payment of the principal of Securities of such series which shall have become due by acceleration, shall have
been cured, waived or otherwise remedied as provided herein—then and in every such case the Holders of a majority in aggregate principal amount of all the Securities of such series then Outstanding, by written notice to the Issuer and to the
Trustee, may waive all defaults with respect to such series and rescind and annul such declaration and its consequences, but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or shall impair any right
consequent thereon. 
 Unless otherwise indicated in the Board Resolution, Officer’s Certificate or supplemental indenture for a series
of Original Issue Discount Securities, for all purposes under this Indenture, if a portion of the principal of any Original Issue Discount Securities shall have been accelerated and declared due and payable pursuant to the provisions hereof, then,
from and after such declaration, unless such declaration has been rescinded and annulled, the principal amount of such Original Issue Discount Securities shall be deemed, for all purposes hereunder, to be such portion of the principal thereof as
shall be due and payable as a result of such acceleration, and payment of such portion of the principal thereof as shall be due and payable as a result of such acceleration, together with interest, if any, thereon and all other amounts owing
thereunder, shall constitute payment in full of such Original Issue Discount Securities. 
 Section 5.02 Collection of Debt by
Trustee; Trustee May Prove Debt. The Issuer covenants that (a) in case default shall be made in the payment of any installment of interest on any of the Securities of any series when such interest shall have become due and payable, and
such default shall have continued for a period of 30 days or (b) in case default shall be made in the payment of all or any part of the principal of any of the Securities of any series when the same shall have become due and payable, whether
upon maturity of the Securities of such series or upon any redemption or by declaration or otherwise—then, upon demand of the Trustee, the Issuer will pay to the Trustee for the benefit of the Holders of the Securities of such series the whole
amount that then shall have become due and payable on all Securities of such series for principal or interest, as the case may be (with interest to the date of such payment upon the overdue principal and, to the extent that payment of such interest
is enforceable under applicable law, on overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities of such series); and, in addition
thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee and each predecessor trustee, their respective agents, attorneys and counsel, and any expenses and
liabilities incurred, and all advances made, by the Trustee and each predecessor trustee except as a result of its negligence or bad faith. 

  
 17 

 In case the Issuer shall fail forthwith to pay such amounts upon such demand, the Trustee, in its
own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceedings to judgment or
final decree, and may enforce any such judgment or final decree against the Issuer or other obligor upon such Securities and collect in the manner provided by law out of the property of the Issuer or other obligor upon such Securities, wherever
situated, the moneys adjudged or decreed to be payable. 
 In case there shall be pending proceedings relative to the Issuer or any other
obligor upon the Securities under Title 11 of the United States Code or any other applicable Federal or state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
sequestrator or similar official shall have been appointed for or taken possession of the Issuer or its property or such other obligor or its property, or in case of any other comparable judicial proceedings relative to the Issuer or other obligor
upon the Securities of any series, or to the creditors or property of the Issuer or such other obligor, the Trustee, irrespective of whether the principal of any Securities shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such proceedings or otherwise: 

(i) to file and prove a claim or claims for the whole amount of principal and interest (or, if the Securities of any series are
Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of such series) owing and unpaid in respect of the Securities of any series, and to file such other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for reasonable compensation to the Trustee and each predecessor trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and
liabilities incurred, and all advances made, by the Trustee and each predecessor trustee, except as a result of negligence or bad faith) and of the Securityholders allowed in any judicial proceedings relative to the Issuer or other obligor upon the
Securities of any series, or to the creditors or property of the Issuer or such other obligor, 
 (ii) unless prohibited by
applicable law and regulations, to vote on behalf of the Holders of the Securities of any series in any election of a trustee or a standby trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings or person
performing similar functions in comparable proceedings, and 
 (iii) to collect and receive any moneys or other property
payable or deliverable on any such claims, and to distribute all amounts received with respect to the claims of the Securityholders and of the Trustee on their behalf; and any trustee, receiver or liquidator, custodian or other similar official is
hereby authorized by each of the Securityholders to make payments to the Trustee, and, in the event that the Trustee shall consent to the making of payments directly to the Securityholders, to pay to the Trustee such amounts as shall be sufficient
to cover reasonable compensation to the Trustee, each predecessor trustee and their respective agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor trustee except
as a result of negligence or bad faith and all other amounts due to the Trustee or any predecessor trustee pursuant to Section 6.06. 

  
 18 

 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or
vote for or accept or adopt on behalf of any Securityholder any plan of reorganization, arrangement, adjustment or composition affecting the Securities of any series or the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Securityholder in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar person. 

All rights of action and of asserting claims under this Indenture, or under any of the Securities of any series, may be enforced by the
Trustee without the possession of any of the Securities of such series or the production thereof on any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Trustee, each predecessor trustee and their respective agents and attorneys, shall be for the ratable benefit of
the Holders of the Securities in respect of which such action was taken. 
 In any proceedings brought by the Trustee (and also any
proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party), the Trustee shall be held to represent all the Holders of the Securities in respect to which such action was taken, and it shall not
be necessary to make any Holders of such Securities parties to any such proceedings. 
 Section 5.03 Application of
Proceeds. Any moneys collected by the Trustee pursuant to this Article in respect of any series shall be applied in the following order at the date or dates fixed by the Trustee and, in case of the distribution of such moneys on account of
principal or interest, upon presentation of the several Securities in respect of which monies have been collected and stamping (or otherwise noting) thereon the payment, or issuing Securities of such series in reduced principal amounts in exchange
for the presented Securities of like series if only partially paid, or upon surrender thereof if fully paid: 
 FIRST: To the
payment of all amounts due to the Trustee or any predecessor trustee pursuant to Section 6.06; 
 SECOND: In case the
principal of the Securities of such series in respect of which moneys have been collected shall not have become and be then due and payable, to the payment of interest on the Securities of such series in default in the order of the maturity of the
installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest, to the extent permitted by applicable law, at the same rate as the rate of interest or Yield
to Maturity (in the case of Original Issue Discount Securities) specified in such Securities, such payments to be made ratably to the Persons entitled thereto, without discrimination or preference; 

THIRD: In case the principal of the Securities of such series in respect of which moneys have been collected shall have become
and shall be then due and payable, to the payment of the whole amount then owing and unpaid upon all the Securities of such series for principal and interest, with interest upon the overdue principal, and (to the extent that such interest has been
collected by the Trustee) upon overdue installments of interest, to the extent permitted by applicable law, at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities
of such series; and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Securities of such series, then to the payment of such principal and interest or Yield to Maturity, without preference or
priority of principal over interest or Yield to Maturity, or of interest or Yield to Maturity over principal, or of any installment of interest over any other installment of interest, or of any Security of such series over any other security of such
series, ratably to the aggregate of such principal and accrued and unpaid interest or Yield to Maturity; and 

  
 19 

 FOURTH: To the payment of the remainder, if any, to the Issuer or any other
Person lawfully entitled thereto. 
 Section 5.04 Suits for Enforcement. In case an Event of Default has occurred, has
not been waived and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce
any such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture or to enforce
any other legal or equitable right vested in the Trustee by this Indenture or by law. 
 Section 5.05 Restoration of Rights on
Abandonment of Proceedings. In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the
Trustee, then and in every such case (subject to any determination in such proceeding) the Issuer and the Trustee shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Issuer, the
Trustee and the Securityholders shall continue as though no such proceedings had been taken. 
 Section 5.06 Limitations on Suits
by Securityholders. No Holder of any Security of any series shall have any right by virtue or by availing of any provision of this Indenture to institute any action or proceeding at law or in equity or in bankruptcy or otherwise upon or
under or with respect to this Indenture, or for the appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice
of default and of the continuance thereof, as hereinbefore provided, and unless also the Holders of not less than 25% in aggregate principal amount of the Securities of such series then Outstanding shall have made written request upon the Trustee to
institute such action or proceedings in its own name as trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby and the Trustee
for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to
Section 5.09; it being understood and intended, and being expressly covenanted by the Holder of every Security with every other Holder and the Trustee, that no one or more Holders of Securities of any series shall have any right in any manner
whatever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other such Holder of Securities, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce
any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of Securities of the applicable series. For the protection and enforcement of the provisions of this Section, each and
every Securityholder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 
 Section 5.07
Unconditional Right of Securityholders to Institute Certain Suits. Notwithstanding any other provision in this Indenture and any provision of any Security, the right of any Holder of any Security to receive payment of the principal of
and interest on such Security on or after the respective due dates expressed in such Security in accordance with the terms hereof and thereof, or to institute suit for the enforcement of any such payment on or after such respective dates, or for the
enforcement of such conversion right, shall not be impaired or affected without the consent of such Holder; it being understood and intended, and being expressly covenanted by the Holder of every Security with every other Holder and the Trustee,
that no one or more Holders of Securities of any series shall have any right in any manner whatever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other such Holder of Securities, or to
obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of Securities of the
applicable series. For the protection and enforcement of the provisions of this Section, each and every Securityholder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

  
 20 

 Section 5.08 Powers and Remedies Cumulative; Delay or Omission Not Waiver of
Default. Except as provided in Section 5.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities is intended to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise,
shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 No delay or omission of the Trustee or
of any Holder of Securities to exercise any right or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or an
acquiescence therein; and, subject to Section 5.06, every power and remedy given by this Indenture or by law to the Trustee or to the Holders of Securities may be exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Holders of Securities. 
 Section 5.09 Control by Holders of Securities. The Holders of a majority in
aggregate principal amount of the Securities of each series affected (with each series voting as a separate class) at the time Outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred on the Trustee with respect to the Securities of such series by this Indenture; provided, that such direction shall not be otherwise than in accordance with law and the provisions
of this Indenture and provided, further, that (subject to the provisions of Section 6.01) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, shall determine that the action or
proceeding so directed may not lawfully be taken or if the Trustee in good faith by its board of directors, the executive committee, or a trust committee of directors or Responsible Officers of the Trustee shall determine that the action or
proceedings so directed would involve the Trustee in personal liability or if the Trustee in good faith shall so determine that the actions or forbearances specified in or pursuant to such direction would be unduly prejudicial to the interests of
Holders of the Securities of all series so affected not joining in the giving of said direction, it being understood that (subject to Section 6.01) the Trustee shall have no duty to ascertain whether or not such actions or forbearances are
unduly prejudicial to such Holders. 
 Nothing in this Indenture shall impair the right of the Trustee in its discretion to take any action
deemed proper by the Trustee and which is not inconsistent with such direction or directions by Securityholders. 
 Section 5.10
Waiver of Past Defaults. Prior to the declaration of the acceleration of the maturity of the Securities of any series as provided in Section 5.01, the Holders of a majority in aggregate principal amount of the Securities of such
series at the time Outstanding, by notice to the Trustee, may on behalf of the Holders of all the Securities of such series waive any existing default in the performance of any of the covenants contained herein or established pursuant to
Section 2.03 with respect to such series and its consequences, except a default in the payment of the principal of, or interest on, any of the Securities of that series as and when the same shall become due by the terms of such Securities. In
the case of any such waiver, the Issuer, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights hereunder, respectively, such default shall cease to exist and be deemed to have been cured
and not to have occurred, and any Event of Default arising therefrom shall be deemed to have been cured, and not to have occurred for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of
Default or impair any right consequent thereon. 

  
 21 

 Section 5.11 Trustee to Give Notice of Default. The Trustee shall, within 90
days after the occurrence of a default with respect to the Securities of any series, give notice of all defaults with respect to that series known to the Trustee to all Holders of Securities of such series in the manner and to the extent provided in
Section 4.03, unless in each case such defaults shall have been cured before the mailing or publication of such notice (the term “defaults” for the purpose of this Section being hereby defined to mean any event or condition which is,
or with notice or lapse of time or both would become, an Event of Default); provided, that, except in the case of default in the payment of the principal of or interest on any of the Securities of such series, or in the payment of any sinking fund
installment on such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee, or a trust committee of directors or trustees and/or Responsible Officers of the Trustee in good
faith determines that the withholding of such notice is in the interests of the Securityholders of such series. 
 Section 5.12
Right of Court to Require Filing of Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Security by his or her acceptance thereof shall be deemed to have agreed, that any court may in its discretion
require, in any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to
pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Securityholder or group of Securityholders of any series holding in the aggregate more than
10% in aggregate principal amount of the Securities of such series, or to any suit instituted by any Securityholder for the enforcement of the payment of the principal of or interest on any Security of such series, on or after the respective due
dates expressed in such Security or established pursuant to this Indenture. 
 ARTICLE 6 

CONCERNING THE TRUSTEE 

Section 6.01 Duties and Responsibilities of the Trustee; During Default; Prior to Default. With respect to the Holders of
any series of Securities issued hereunder, the Trustee, prior to the occurrence of an Event of Default with respect to the Securities of a particular series and after the curing or waiving of all Events of Default which may have occurred with
respect to such series, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default with respect to the Securities of a series has occurred (which has not been cured or waived),
the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own
affairs. 
 No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own
negligent failure to act or its own willful misconduct. 
 Section 6.02 Certain Rights of the Trustee. In furtherance of
and subject to the Trust Indenture Act of 1939 and subject to Section 6.01: 
 (a) in the absence of bad faith on the part of
the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any statements, certificates or opinions furnished to the Trustee and conforming to the requirements of
this Indenture; but, in the case of any such statements, certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or
not they conform to the requirements of this Indenture; 

  
 22 

 (b) the Trustee shall not be liable for any error of judgment made in good faith
by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 

(c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance
with the direction of the Holders pursuant to Section 5.09 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this
Indenture; 
 (d) none of the provisions contained in this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers if there shall be reasonable ground for believing that the repayment of such funds or adequate indemnity
against such liability is not reasonably assured to it; 
 (e) the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, Officer’s Certificate or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note, security or other paper or document believed by it to be
genuine and to have been signed or presented by the proper party or parties; 
 (f) any request, direction, order or demand
of the Issuer mentioned herein shall be sufficiently evidenced by an Officer’s Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the
Trustee by a copy thereof certified by the secretary or an assistant secretary of the Issuer; 
 (g) the Trustee may consult
with counsel and any advice or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted to be taken by it hereunder in good faith and in accordance with such advice or Opinion of
Counsel; 
 (h) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this
Indenture at the request, order or direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and
liabilities which might be incurred therein or thereby; 
 (i) the Trustee shall not be liable for any action taken or
omitted by it in good faith and believed by it to be authorized or within the discretion, rights or powers conferred upon it by this Indenture; 

(j) prior to the occurrence of an Event of Default hereunder and after the curing or waiving of all Events of Default, the
Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, appraisal, bond, debenture, note, security, or
other paper or document unless requested in writing so to do by the Holders of not less than a majority in aggregate principal amount of the Securities of all series affected then Outstanding; provided, that, if the payment within a reasonable time
to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this
Indenture, the Trustee may require reasonable indemnity against such expenses or liabilities as a condition to proceeding; the reasonable expenses of every such investigation shall be paid by the Issuer or, if paid by the Trustee or any predecessor
trustee, shall be repaid by the Issuer upon demand; and 

  
 23 

 (k) the Trustee may execute any of the trusts or powers hereunder or perform any
duties hereunder either directly or by or through agents or attorneys not regularly in its employ and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed with due care by it
hereunder. 
 Section 6.03 Trustee Not Responsible for Recitals, Disposition of Securities or Application of Proceeds
Thereof. The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Issuer, and the Trustee assumes no responsibility for the correctness of the
same. The Trustee makes no representation as to the validity or sufficiency of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Issuer of any of the Securities or of the proceeds thereof.

 Section 6.04 Trustee and Agents May Hold Securities; Collections, Etc. The Trustee or any agent of the Issuer or the
Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities with the same rights it would have if it were not the Trustee or such agent and may otherwise deal with the Issuer and receive, collect, hold and retain
collections from the Issuer with the same rights it would have if it were not the Trustee or such agent. 
 Section 6.05 Moneys
Held by Trustee. Subject to the provisions of Section 10.04 hereof, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be
segregated from other funds except to the extent required by mandatory provisions of law. Neither the Trustee nor any agent of the Issuer or the Trustee shall be under any liability for interest on any moneys received by it hereunder. 

Section 6.06 Compensation and Indemnification of Trustee and Its Prior Claim. The Issuer covenants and agrees to pay to the
Trustee from time to time, and the Trustee shall be entitled to, such reasonable compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as the Issuer and the Trustee may from
time to time agree in writing and, except as otherwise expressly provided herein, the Issuer covenants and agrees to pay or reimburse the Trustee and each predecessor trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its
employ) except any such expense, disbursement or advance as may arise from its negligence or bad faith. The Issuer also covenants to indemnify the Trustee and each predecessor trustee for, and to hold it harmless against, any loss, liability or
expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder and its duties hereunder, including the costs and expenses of defending
itself against or investigating any claim of liability in the premises. The obligations of the Issuer under this Section to compensate and indemnify the Trustee and each predecessor trustee and to pay or reimburse the Trustee and each predecessor
trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture. Such additional indebtedness shall be a senior claim to that of the Securities
upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities, and the Securities are hereby subordinated to such senior claim. 

  
 24 

 Section 6.07 Right of Trustee to Rely on Officer’s Certificate, Etc.
Subject to Sections 6.01 and 6.02, whenever in the administration of the trusts of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action hereunder,
such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officer’s Certificate
delivered to the Trustee, and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this Indenture upon
the faith thereof. 
 Section 6.08 Disqualification; Conflicting Interests. If the Trustee has or shall acquire any
“conflicting interest” within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the Issuer shall in all respects comply with the provisions of Section 310(b) of the Trust Indenture Act. 

Section 6.09 Persons Eligible for Appointment as Trustee. The Trustee for each series of Securities hereunder shall at all
times be a corporation having a combined capital and surplus of at least $50,000,000 and shall be eligible in accordance with the provisions of Section 310(a) of the Trust Indenture Act of 1939. If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of a Federal, State or District of Columbia supervising or examining authority, then, for the purposes of this Section, the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. 
 Section 6.10
Resignation and Removal; Appointment of Successor Trustee. (a) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign with respect to one or more or all series of Securities by giving written notice of
resignation to the Issuer and by mailing notice of such resignation to the Holders of then Outstanding Securities of each series affected at their addresses as they shall appear on the Security register. Upon receiving such notice of resignation,
the Issuer shall promptly appoint a successor trustee or trustees with respect to the applicable series by written instrument in duplicate, executed by authority of the Board of Directors, one copy of which instrument shall be delivered to the
resigning Trustee and one copy to the successor trustee or trustees. If no successor trustee shall have been so appointed with respect to any series and have accepted appointment within 30 days after the mailing of such notice of resignation, the
resigning trustee may petition any court of competent jurisdiction for the appointment of a successor trustee, or any Holder of a Security who has been a bona fide Holder of a Security or Securities of the applicable series for at least six months
may, on behalf of himself or herself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor
trustee. 
 (b) In case at any time any of the following shall occur: 

(i) the Trustee shall fail to comply with the provisions of Section 310(b) of the Trust Indenture Act of 1939 with respect
to any series of Securities after written request therefor by the Issuer or by any Holder of a Security who has been a bona fide Holder of a Security or Securities of such series for at least six months; or 

(ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 310(a) of the Trust Indenture Act
of 1939 and shall fail to resign after written request therefor by the Issuer or by any Holder of a Security; or 
 (iii) the
Trustee shall become incapable of acting with respect to any series of Securities, or shall be adjudged bankrupt or insolvent, or a receiver or liquidator of the Trustee or of its property shall be appointed, or any public officer shall take charge
or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation; 

  
 25 

 then, in any such case, (A) the Issuer may remove the Trustee with respect to the applicable series of
Securities and appoint a successor trustee for such series by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor
trustee, or, (B) subject to Section 315(e) of the Trust Indenture Act of 1939, any Holder of a Security who has been a bona fide Holder of a Security or Securities of such series for at least six months may on behalf of himself or herself
and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee with respect to such series. Such court may thereupon, after such notice, if any, as it may
deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
 (c) The Holders of a majority in aggregate
principal amount of the Securities of each series at the time Outstanding may at any time remove the Trustee with respect to Securities of such series and, with the consent of the Issuer, appoint a successor trustee with respect to the Securities of
such series by delivering to the Trustee so removed, to the successor trustee so appointed and to the Issuer the evidence provided for in Section 7.01 of the action in that regard taken by the Securityholders. 

(d) Any resignation or removal of the Trustee with respect to any series and any appointment of a successor trustee with
respect to such series pursuant to any of the provisions of this Section 6.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 6.11. 

Section 6.11 Acceptance of Appointment by Successor Trustee. Any successor trustee appointed as provided in
Section 6.10 shall execute and deliver to the Issuer and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee with respect to all or any applicable
series shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all rights, powers, duties and obligations with respect to such series of its predecessor hereunder, with like effect as
if originally named as trustee for such series hereunder; but, nevertheless, on the written request of the Issuer or of the successor trustee, upon payment of its charges then unpaid, the trustee ceasing to act shall, subject to Section 10.04,
pay over to the successor trustee all moneys at the time held by it hereunder and shall execute and deliver an instrument transferring to such successor trustee all such rights, powers, duties and obligations. Upon request of any such successor
trustee, the Issuer shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a prior claim
upon all property or funds held or collected by such trustee to secure any amounts then due it pursuant to the provisions of Section 6.06. 

If a successor trustee is appointed with respect to the Securities of one or more (but not all) series, the Issuer, the predecessor trustee
and each successor trustee with respect to the Securities of any applicable series shall execute and deliver an indenture supplemental hereto which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the predecessor trustee with respect to the Securities of any series as to which the predecessor trustee is not retiring shall continue to be vested in the predecessor trustee, and shall add to or change any of
the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such
trustees co-trustees of the same trust and that each such trustee shall be trustee of a trust or trusts under separate indentures. 

  
 26 

 No successor trustee with respect to any series of Securities shall accept appointment as
provided in this Section 6.11 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of Section 310(b) of the Trust Indenture Act of 1939 and eligible under the provisions of
Section 310(a) of the Trust Indenture Act of 1939. 
 Upon acceptance of appointment by any successor trustee as provided in this
Section 6.11, the Issuer shall mail notice thereof to the Holders of Securities of each series affected, by mailing such notice to such Holders at their addresses as they shall appear on the Security register. If the acceptance of appointment
is substantially contemporaneous with the resignation, then the notice called for by the preceding sentence may be combined with the notice called for by Section 6.10. If the Issuer fails to mail such notice within ten days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such notice to be given at the expense of the Issuer. 

Section 6.12 Merger, Conversion, Consolidation or Succession to Business of Trustee. Any corporation into which the Trustee
may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder; provided, that such corporation shall be qualified under the provisions of Section 310(b) of the Trust Indenture Act of 1939 and eligible under the provisions of Section 310(a) of
the Trust Indenture Act of 1939, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. 

In case, at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Securities of any series
shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee and deliver such Securities so authenticated; and, in case at that time any of the Securities
of any series shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor trustee; and in all such cases such certificate shall have
the full force which it is anywhere in the Securities of such series or in this Indenture provided that the certificate of the Trustee shall have; provided, that the right to adopt the certificate of authentication of any predecessor trustee or to
authenticate Securities of any series in the name of any predecessor trustee shall apply only to its successor or successors by merger, conversion or consolidation. 

Section 6.13 Preferential Collection of Claims Against the Issuer. The Trustee shall comply with Section 311(a) of the
Trust Indenture Act, excluding any creditor relationship described in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent
included therein. 
 ARTICLE 7 

CONCERNING THE SECURITYHOLDERS 

Section 7.01 Evidence of Action Taken by Securityholders. Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by a specified percentage in principal amount of the Securityholders of any or all series may be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such specified percentage of Securityholders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to
the Trustee. Proof of execution of any instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Sections 6.01 and 6.02) conclusive in favor of the Trustee and the Issuer, if made in
the manner provided in this Article. 

  
 27 

 Section 7.02 Proof of Execution of Instruments and of Holding of Securities.
Subject to Sections 6.01 and 6.02, the execution of any instrument by a Holder or his agent or proxy may be proved by the affidavit of a witness to such execution or by the certificate of any notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by an officer of a corporation or a member of a partnership or limited liability company,
on behalf of such corporation, partnership or limited liability company, such certificate or affidavit shall also constitute sufficient proof of his authority. The execution of any such instrument or writing, or the authority of the person executing
the same, may also be proved in any other manner which the Trustee deems sufficient. The holding of Securities shall be proved by the Security register or by a certificate of the registrar thereof. The Issuer may set a record date for purposes of
determining the identity of Holders of any series entitled to vote or consent to any action referred to in Section 7.01, which record date may be set at any time or from time to time by notice to the Trustee, for any date or dates (in the case
of any adjournment or reconsideration) not more than 60 days nor less than five days prior to the proposed date of such vote or consent, and thereafter, notwithstanding any other provisions hereof, only Holders of such series of record on such
record date shall be entitled to so vote or give such consent or revoke such vote or consent. Notice of such record date may be given before or after any request for any action referred to in Section 7.01 is made by the Issuer. 

Section 7.03 Holders to Be Treated as Owners. The Issuer, the Trustee and any agent of the Issuer or of the Trustee may
deem and treat the Person in whose name any Security shall be registered upon the Security register for such series as the absolute owner of such Security (whether or not such Security shall be overdue and notwithstanding any notation of ownership
or other writing thereon) for the purpose of receiving payment of or on account of the principal of, and, subject to the provisions of this Indenture, interest on, such Security and for all other purposes; and neither the Issuer nor the Trustee nor
any agent of the Issuer or the Trustee shall be affected by any notice to the contrary. All such payments so made to any such Person, or upon his or her order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and
discharge the liability for moneys payable. 
 Section 7.04 Securities Owned by Issuer Deemed Not Outstanding. In
determining whether the Holders of the requisite aggregate principal amount of Outstanding Securities of any or all series have concurred in any direction, consent or waiver under this Indenture, Securities which are owned by the Issuer or any other
obligor on the Securities with respect to which such determination is being made or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any other obligor on the Securities
with respect to which such determination is being made shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that, for the purpose of determining whether the Trustee shall be protected in relying on
any such direction, consent or waiver, only Securities which the Trustee knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be regarded as Outstanding if the pledgee establishes to the
satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not the Issuer or any other obligor upon the Securities or any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Issuer or any other obligor on the Securities. In case of a dispute as to such right, the advice of counsel shall be full protection in respect of any decision made by the Trustee in accordance with such
advice. 
 Section 7.05 Right of Revocation of Action Taken. At any time prior to (but not after) the evidencing to the
Trustee, as provided in Section 7.01, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Securities of any or all series, as the case may be, specified in this Indenture in connection with such
action, any Holder of a Security the serial number of which is shown by the evidence to be included among the serial numbers of the Securities the Holders of which have consented to such action may, by filing written notice at the Corporate Trust
Office and upon proof of holding as provided in this Article, revoke such action so far as concerns such Security. Except as aforesaid, any such action taken by the Holder of any Security shall be conclusive and binding upon such Holder and upon all
future Holders and owners of such Security and of any Securities issued in exchange or substitution therefor or on registration of transfer thereof, irrespective of whether or not any notation in regard thereto is made upon any such Security. Any
action taken by the Holders of the percentage in aggregate principal amount of the Securities of any or all series, as the case may be, specified in this Indenture in connection with such action shall be conclusively binding upon the Issuer, the
Trustee and the Holders of all the Securities affected by such action. 

  
 28 

 ARTICLE 8 

SUPPLEMENTAL INDENTURES 

Section 8.01 Supplemental Indentures Without Consent of Securityholders. The Issuer, when authorized by a resolution of its
Board of Directors, and the Trustee may from time to time and at any time, without the consent of any of the Securityholders, enter into an indenture or indentures supplemental hereto in form satisfactory to the Trustee for one or more of the
following purposes: 
 (a) to convey, transfer, assign, mortgage or pledge to the Trustee as security for the Securities of
one or more series any property or assets; 
 (b) to evidence the succession of a corporation, limited liability company,
partnership or trust to the Issuer, or successive successions, and the assumption by such successor of the covenants, agreements and obligations of the Issuer pursuant to Article 9; 

(c) to add to the covenants of the Issuer such further covenants, restrictions, conditions or provisions as its Board of
Directors shall consider to be for the protection of the Holders of Securities, and to make the occurrence, or the occurrence and continuance, of a default in any such additional covenants, restrictions, conditions or provisions an Event of Default
permitting the enforcement of all or any of the several remedies provided in this Indenture as herein set forth; provided, that in respect of any such additional covenant, restriction, condition or provision such supplemental indenture may provide
for a particular period of grace after default (which period may be shorter or longer than that allowed in the case of other defaults) or may provide for an immediate enforcement upon such an Event of Default or may limit the remedies available to
the Trustee upon such an Event of Default or may limit the right of the Holders of a majority in aggregate principal amount of the Securities of such series to waive such an Event of Default; 

(d) to cure any ambiguity, defect or inconsistency, or to conform this Indenture or any supplemental indenture to the
description of the Securities set forth in any prospectus or prospectus supplement related to such series of Securities; 

(e) to provide for or add guarantors for the Securities of one or more series; 

(f) to establish the form or terms of Securities of any series as permitted by Sections 2.01 and 2.03; 

(g) to evidence and provide for the acceptance of appointment hereunder by a successor trustee with respect to the Securities
of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one trustee, pursuant to the requirements of
Section 6.11; 
 (h) to add to, delete from or revise the conditions, limitations and restrictions on the authorized
amount, terms, purposes of issue, authentication and delivery of any series of Securities, as herein set forth; 

  
 29 

 (i) to make any change to the Securities of any series so long as no Securities
of such series are Outstanding; and 
 (j) to make any other change that does not adversely affect the interests of the
Holders of the Securities in any material respect. 
 The Trustee shall join with the Issuer in the execution of any such supplemental
indenture, to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the Trustee shall not be obligated to enter
into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 

Any supplemental indenture authorized by the provisions of this Section may be executed without the consent of the Holders of any of the
Securities at the time Outstanding, notwithstanding any of the provisions of Section 8.02. 
 Section 8.02 Supplemental
Indentures With Consent of Securityholders. With the consent (evidenced as provided in Article 7) of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of one or more series
affected by such supplemental indenture (voting as separate series), the Issuer, when authorized by a resolution of the Board of Directors, and the Trustee may, from time to time and at any time, enter into an indenture or indentures supplemental
hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Securities of each
such consenting series; provided, that no such supplemental indenture shall, without the consent of the Holder of each Security so affected, (a) extend the final maturity of any Security, or reduce the principal amount thereof, or reduce the
rate or extend the time of payment of interest thereon, or reduce any amount payable on redemption thereof, or make the principal thereof (including any amount in respect of original issue discount) or interest thereon payable in any currency other
than that provided in the Securities or in accordance with the terms thereof, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon an acceleration of the maturity thereof pursuant to
Section 5.01 or the amount thereof provable in bankruptcy pursuant to Section 5.02, or waive a default in the payment of principal of any Security or interest thereon or change a provision related to the waiver of past defaults or changes
or impair the right of any Securityholder to institute suit for the payment or conversion thereof or, if the Securities provide therefor, any right of repayment at the option of the Securityholder, or (b) modify any of the provisions of this
section except to increase any required percentage or to provide that certain other provisions cannot be modified or waived without the consent of the Holder of each Security so affected, or (c) reduce the aforesaid percentage of Securities of
any series, the consent of the Holders of which is required for any such supplemental indenture or the consent of Holders of which is required for any modification, amendment or waiver of compliance with certain provisions of this Indenture or
certain defaults hereunder and their consequences provided for in this Indenture. 
 A supplemental indenture which changes or eliminates
any covenant, Event of Default or other provision of this Indenture (1) that has been expressly included solely for the benefit of one or more particular series of Securities, if any, or (2) which modifies the rights of Holders of
Securities of one or more series with respect to any covenant, Event of Default or provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series with respect to which such covenant, Event
of Default or other provision has not be modified. 

  
 30 

 Upon the request of the Issuer, accompanied by a Board Resolution authorizing the execution of
any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Securityholders as aforesaid and other documents, if any, required by Section 7.01, the Trustee shall join with the Issuer in the execution of
such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into
such supplemental indenture. 
 It shall not be necessary for the consent of the Securityholders under this Section to approve the
particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. 

Promptly after the execution by the Issuer and the Trustee of any supplemental indenture pursuant to the provisions of this Section, the
Trustee shall give a notice thereof to the Holders of then Outstanding Securities of each series affected thereby, by mailing a notice thereof by first-class mail to such Holders at their addresses as they shall appear on the Security register, and
in each case such notice shall set forth in general terms the substance of such supplemental indenture. Any failure of the Trustee to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such
supplemental indenture. 
 Section 8.03 Effect of Supplemental Indenture. Upon the execution of any supplemental
indenture pursuant to the provisions hereof, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the
Trustee, the Issuer and the Holders of Securities of each series affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any
such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 

Section 8.04 Documents to Be Given to Trustee. The Trustee, subject to the provisions of Sections 6.01 and
6.02, may receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant to this Article 8 complies with the applicable provisions of this Indenture. 

Section 8.05 Notation on Securities in Respect of Supplemental Indentures. Securities of any series authenticated and
delivered after the execution of any supplemental indenture pursuant to the provisions of this Article may bear a notation in form approved by the Trustee for such series as to any matter provided for by such supplemental indenture or as to any
action taken by Securityholders. If the Issuer or the Trustee shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in
any such supplemental indenture may be prepared by the Issuer, authenticated by the Trustee and delivered in exchange for the Securities of such series then Outstanding. 

ARTICLE 9 

CONSOLIDATION, MERGER, SALE OR CONVEYANCE 

Section 9.01 Issuer May Consolidate, Etc., on Certain Terms. The Issuer shall not consolidate with or merge
into any other Person (in a transaction in which the Issuer is not the surviving corporation) or convey, transfer or lease its properties and assets as an entirety or substantially as an entirety to any Person, unless (a) the Person formed by
such consolidation or into which the Issuer is merged or the Person which acquires by conveyance or transfer, or which leases, the properties and assets of the Issuer as an entirety or substantially as an entirety (i) shall be a corporation,
limited liability company, partnership or trust, (ii) shall be organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia and (iii) shall expressly assume, by an indenture
supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, the due and punctual payment of the principal of and interest on all the Securities and the performance or observance of every covenant of this
Indenture on the part of the Issuer to be performed, by supplemental indenture satisfactory in form to the Trustee, executed and delivered to the Trustee, by the Person formed by such consolidation or into which the Issuer shall have been merged or
by the Person which shall have acquired the Issuer’s assets; (b) immediately after giving effect to such transaction and treating any indebtedness which becomes an obligation of the Issuer or any Subsidiary as a result of such transaction
as having been incurred by the Issuer or such Subsidiary at the time of such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing; and
(c) the Issuer has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with
such transaction, such supplemental indenture comply with this Article and that all conditions precedent herein provided for relating to such transaction have been complied with. 

  
 31 

 The conditions of (a)(ii) above shall not apply in the case of a corporation or entity not
organized under the laws of the United States of America, any State thereof or the District of Columbia which shall agree, in form satisfactory to the Trustee, (i) to subject itself to the jurisdiction of the United States district court for
the Southern District of New York and (ii) to indemnify and hold harmless the holders of all Securities against (A) any tax, assessment or governmental charge imposed on such holders by a jurisdiction other than the United States or any
political subdivision or taxing authority thereof or therein with respect to, and withheld on the making of, any payment of principal or interest on such Securities and which would not have been so imposed and withheld had such consolidation,
merger, sale or conveyance not been made and (B) any tax, assessment or governmental charge imposed on or relating to, and any costs or expenses involved in, such consolidation, merger, sale or conveyance. 

The restrictions in this Section 9.01 shall not apply to (i) the merger or consolidation of the Issuer with one of its affiliates,
if the Board of Directors determines in good faith that the purpose of such transaction is principally to change the Issuer’s State of incorporation or convert the Issuer’s form of organization to another form, or (ii) the merger of
the Issuer with or into a single direct or indirect wholly owned Subsidiary. 
 Nothing contained in this Article shall apply to, limit or
impose any requirements upon the consolidation or merger of any Person into the Issuer where the Issuer is the survivor of such transaction, or the acquisition by the Issuer, by purchase or otherwise, of all or any part of the property of any other
Person (whether or not affiliated with the Issuer). 
 Section 9.02 Successor Issuer Substituted. Upon any consolidation
of the Issuer with, or merger of the Issuer into, any other Person or any conveyance, transfer or lease of the properties and assets of the Issuer as an entirety or substantially as an entirety in accordance with Section 9.01, the successor
Person formed by such consolidation or into which the Issuer is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer under this Indenture with
the same effect as if such successor Person had been named as the Issuer herein, and thereafter, except in the case of a lease, the predecessor Person shall be relieved of all obligations and covenants under this Indenture and the Securities. 

In case of any such consolidation, merger, sale, lease or conveyance, such changes in phraseology and form (but not in substance) may be made
in the Securities thereafter to be issued as may be appropriate.

and if, in any such case (i), (ii) or (iii), the Issuer shall also pay or cause to be paid all other sums payable hereunder by the Issuer, including

Trustee’s obligations under Sections 10.02 and 10.04 and (5) the obligations of the Issuer under Section 3.02), and the Trustee, on demand of the Issuer accompanied by an Officer’s Certificate and an Opinion of Counsel which
complies with Section 11.05 and at the cost and expense of the Issuer, shall execute proper instruments acknowledging such satisfaction of and discharging this Indenture with respect to such series. The Issuer agrees to reimburse the Trustee

 33 

 (b) The following subsection shall apply to the Securities of each series unless specifically
otherwise provided in a Board Resolution, Officer’s Certificate or indenture supplemental hereto provided pursuant to Section 2.03. In addition to the right to discharge of the Indenture pursuant to subsection (a) above, the Issuer,
at its option and at any time, by written notice by an officer delivered to the Trustee, may elect to have all of its obligations discharged with all Outstanding Securities of a series (“Legal Defeasance”), such discharge to be
effective on the date that the conditions set forth in clauses (i) through (iv) and (vi) of Section 10.01(d) are satisfied, and thereafter the Issuer shall be deemed to have paid and discharged the entire Debt on all the Securities of
such a series, and satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned and this Indenture shall cease to be of further effect with respect to Securities of such series (except as to
(1) rights of registration of transfer, conversion and exchange of Securities of such series, (2) substitution of apparently mutilated, defaced, destroyed, lost or stolen Securities, (3) rights of Holders of Securities to receive,
solely from the trust fund described in Section 10.01(d)(i), payments of principal thereof and interest thereon, upon the original stated due dates therefor (but not upon acceleration) and remaining rights of the Holders to receive, solely from
the trust fund described in Section 10.01(d)(i), sinking fund payments, if any, (4) the rights (including the Trustee’s rights under Section 10.05) and immunities of the Trustee hereunder and the Trustee’s obligations with
respect to the Securities of such series under Sections 10.02 and 10.04 and (5) the obligations of the Issuer under Section 3.02). 

(c) The following subsection shall apply to the Securities of each series unless specifically otherwise provided in a Board Resolution,
Officer’s Certificate or indenture supplemental hereto provided pursuant to Section 2.03. In addition to the right to discharge of the Indenture pursuant to subsection (a) and to Legal Defeasance pursuant to subsection (b), above, the
Issuer, at its option and at any time, by written notice executed by an officer delivered to the Trustee, may elect to have its obligations under any covenant contained in this Indenture or in the Board Resolution or supplemental indenture relating
to such series pursuant to Section 2.03 discharged with respect to all Outstanding Securities of a series, this Indenture and any indentures supplemental to this Indenture with respect to such series (“Covenant Defeasance”),
such discharge to be effective on the date the conditions set forth in clauses (i) through (iii) and (v) through (vi) of Section 10.01(d) are satisfied, and such Securities shall thereafter be deemed to be not
“Outstanding” for the purposes of any direction, waiver, consent or declaration of Securityholders (and the consequences of any thereof) in connection with such covenants, but shall continue to be “Outstanding” for all other
purposes under this Indenture. For this purpose, such Covenant Defeasance means that, with respect to the Outstanding Securities of a series, the Issuer may omit to comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of reference in any such covenant to any other provision herein or in any other document and
such omission to comply shall not constitute an Event of Default under Section 5.01(c) or otherwise, but except as specified in this Section 10.01(c), the remainder of the Issuer’s obligations under the Securities of such series, this
Indenture, and any indentures supplemental to this Indenture with respect to such series shall be unaffected thereby. 

  
 34 

 (d) The following shall be the conditions to the application of Legal Defeasance under subsection
(b) or Covenant Defeasance under subsection (c) to the Securities of the applicable series: 
 (i) the Issuer
irrevocably deposits or causes to be deposited in trust with the Trustee or, at the option of the Trustee, with a trustee satisfactory to the Trustee and the Company under the terms of an irrevocable trust agreement in form and substance
satisfactory to the Trustee, cash or U.S. Government Obligations that will generate cash sufficient to pay principal of and interest on the Outstanding Securities of such series to maturity or redemption, as the case may be, and to pay all other
amounts payable by it hereunder, provided that (A) the trustee of the irrevocable trust, if any, shall have been irrevocably instructed to pay such funds or the proceeds of such U.S. Government Obligations to the Trustee and (B) the
Trustee shall have been irrevocably instructed to apply such funds or the proceeds of such U.S. Government Obligations to (x) the principal and interest on all Securities of such series on the date that such principal or interest is due and
payable and (y) any mandatory sinking fund payments on the day on which such payments are due and payable in accordance with the terms of the Indenture and the Securities of such series, and the Issuer shall also pay or cause to be paid all
other amounts payable hereunder with respect to such series;

Certificate stating that all conditions precedent specified herein relating to Legal Defeasance or Covenant Defeasance, as the case may be, have been complied with, and an Opinion of Counsel to the same effect; 

(iii) no Event of Default under subsection (a), (b), (d) or (e) of Section 5.01 shall have occurred and be
continuing, and no event which with notice or lapse of time or both would become such an Event of Default shall have occurred and be continuing, on the date of such deposit; 

(iv) in the event of an election for Legal Defeasance under subsection (b), the Issuer shall have delivered to the Trustee an
Opinion of Counsel stating that (A) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this instrument, there has been a change in the applicable Federal income tax
law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit, defeasance and
discharge to be effected with respect to such Securities and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would be the case if such deposit, defeasance and discharge were not to occur; 

(v) in the event of an election for Covenant Defeasance under subsection (c), the Issuer shall have delivered to the Trustee an
Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with respect to such Securities and will be
subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur; and 

(vi) notwithstanding any other provisions of this subsection (d), such defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed on the Issuer pursuant to Section 2.03. 

  
 35 

 After such irrevocable deposit made pursuant to this Section 10.01(d) and satisfaction of the other

Holders of the particular Securities of such series for the payment or redemption of which such moneys have been deposited with the Trustee, of all sums due and to become due thereon for principal and interest; but such money need not be segregated
from other funds except to the extent required by law. 
 Section 10.03 Repayment of Moneys Held by Paying Agent. In
connection with the satisfaction and discharge of this Indenture with respect to Securities of any series, all moneys then held by any paying agent under the provisions of this Indenture with respect to such series of Securities shall, upon demand
of the Issuer, be repaid to it or paid to the Trustee and thereupon such paying agent shall be released from all further liability with respect to such moneys. 

Section 10.04 Return of Moneys Held by Trustee and Paying Agent Unclaimed for Two Years. Any moneys deposited with or paid
to the Trustee or any paying agent for the payment of the principal of, interest on or additional amounts in respect of any Security of any series and not applied but remaining unclaimed for two years after the date upon which such principal,
interest or additional amount shall have become due and payable, shall be repaid to the Issuer by the Trustee for such series or such paying agent, and the Holder of the Securities of such series shall thereafter look only to the Issuer for any
payment which such Holder may be entitled to collect, and all liability of the Trustee or any paying agent with respect to such moneys shall thereupon cease. 

Section 10.05 Indemnity for U.S. Government Obligations. The Issuer shall pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 10.01 or the principal or interest received in respect of such obligations.

directly or through the Issuer or any such predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that this
Indenture and the obligations issued hereunder are solely corporate obligations, and that no such personal liability whatever shall attach to, or is or shall be incurred by, the incorporators, stockholders, officers or directors as such, of the

Securities or implied therefrom; and that any and all such personal liability of every name and nature, either at common law or in equity or by constitution or statute, of, and any and all such rights and claims against, every such incorporator,
stockholder, officer or director as such, because of the creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants or agreements contained in this Indenture or in any of the Securities or implied therefrom,
are hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issuance of such Securities. 

  
 36 

 Section 11.02 Provisions of Indenture for the Sole Benefit of Parties and Holders of
Securities. Nothing in this Indenture or in the Securities, expressed or implied, shall give or be construed to give to any person, firm or corporation, other than the parties hereto and their successors and the Holders of the Securities any
legal or equitable right, remedy or claim under this Indenture or under any covenant or provision herein contained, all such covenants and provisions being for the sole benefit of the parties hereto and their successors and of the Holders of the
Securities. 
 Section 11.03 Successors and Assigns of Issuer Bound by Indenture. All the covenants, stipulations,
promises and agreements contained in this Indenture by or on behalf of the Issuer shall bind its successors and assigns, whether so expressed or not. 

Section 11.04 Notices and Demands on Issuer, Trustee and Holders of Securities. Any notice or demand which by any provision
of this Indenture is required or permitted to be given or served by the Trustee or by the Holders of Securities to or on the Issuer may be given or served by being deposited postage prepaid, first-class mail (except as otherwise specifically
provided herein) addressed (until another address of the Issuer is filed by the Issuer with the Trustee) to Belden Inc., 1 North Brentwood Boulevard, 15th Floor, St. Louis, Missouri 63105, Attn:
Corporate Secretary. Any notice, direction, request or demand by the Issuer or any Holder of Securities to or upon the Trustee shall be deemed to have been sufficiently given or made, for all purposes, if given or made at
                                        ,
Attn:                                     . 

Where this Indenture provides for notice to Holders of Securities, such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder entitled thereto, at his or her last address as it appears in the Security register. In case, by reason of the suspension of or irregularities in regular mail service,
it shall be impracticable to mail notice of any event to Holders of Securities when said notice is required to be given pursuant to any provision of this Indenture or of the Securities, then any manner of giving such notice as shall be satisfactory
to the Trustee shall be deemed to be a sufficient giving of such notice. 
 In case, by reason of the suspension of or irregularities in
regular mail service, it shall be impracticable to mail notice to the Issuer when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall be
deemed to be a sufficient giving of such notice. 
 Neither the failure to give notice, nor any defect in any notice so given, to any
particular Holder of a Security shall affect the sufficiency of such notice with respect to other Holders of Securities given as provided above. 

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice
either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

Therein. Upon any application or demand by the Issuer to the Trustee to take any action under any of the provisions of this Indenture, the Issuer shall furnish to the Trustee an Officer’s Certificate stating that all conditions
precedent provided for in this Indenture relating to the proposed action have been complied with and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent have been complied with, except that in the case of
any such application or demand as to which the furnishing of such documents is specifically required by any provision of this Indenture relating to such particular application or demand, no additional certificate or opinion need be furnished.

 Any certificate, statement or opinion of an officer of the Issuer may be based, insofar as it relates to legal matters,
upon a certificate or opinion of or representations by counsel, unless such officer knows that the certificate or opinion or representations with respect to the matters upon which his or her certificate, statement or opinion may be based as
aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. Any certificate, statement or opinion of counsel may be based, insofar as it relates to factual matters, information with respect to which is in
the possession of the Issuer, upon the certificate, statement or opinion of or representations by an officer or officers of the Issuer, unless such counsel knows that the certificate, statement or opinion or representations with respect to the
matters upon which his or her certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. 

Any certificate, statement or opinion of an officer of the Issuer or of counsel may be based, insofar as it relates to accounting matters,
upon a certificate or opinion of or representations by an accountant or firm of accountants in the employ of the Issuer, unless such officer or counsel, as the case may be, knows that the certificate or opinion or representations with respect to the
accounting matters upon which his or her certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. 

Section 11.06 Payments Due on Saturdays, Sundays and Holidays. If the date of maturity of interest on or principal of the
Securities of any series or the date fixed for redemption or repayment of any such Security, or the last day on which a Holder has the right to convert any Security, shall not be a Business Day, then payment of interest or principal, or any
conversion, need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the date of maturity or the date fixed for redemption or on such last day for conversion, and no interest
shall accrue for the period after such date. 
 Section 11.07 Conflict of Any Provision of Indenture With Trust Indenture Act of
1939. If and to the extent that any provision of this Indenture limits, qualifies or conflicts with another provision included in this Indenture by operation of Sections 310 to 317, inclusive, of the Trust Indenture Act of 1939, such
incorporated provision shall control. 
 Section 11.08 New York Law to Govern. This Indenture and each Security shall be
deemed to be a contract under the laws of the State of New York, and for all purposes shall be governed by and construed in accordance with the laws of such State without regard to any principle of conflict of laws that would require or permit the
application of the laws of any other jurisdiction, except as may otherwise be required by mandatory provisions of law. 

  
 38 

 Section 11.09 Counterparts. This Indenture may be executed in any number of
counterparts, each of which shall be an original; but such counterparts shall together constitute but one and the same instrument.

committee or officer of any corporation that shall at the time be the lawful successor of the Issuer. 
 Section 11.12
Severability. In case any one or more of the provisions contained in this Indenture or in the Securities of any series shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions of this Indenture or of such Securities, but this Indenture and such Securities shall be construed as if such invalid or illegal or unenforceable provision had never been contained herein or
therein. 
 ARTICLE 12 

REDEMPTION OF SECURITIES AND SINKING FUNDS 

Section 12.01 Applicability of Article. The provisions of this Article shall be applicable to the Securities of any series
which are redeemable before their maturity or to any sinking fund for the retirement of Securities of a series, except as otherwise specified, as contemplated by Section 2.03 for Securities of such series. 

Section 12.02 Notice of Redemption; Partial Redemptions. Notice of redemption to the Holders of Securities of any series to
be redeemed as a whole or in part at the option of the Issuer shall be given by mailing notice of such redemption by first class mail, postage prepaid, at least 15 days and not more than 60 days prior to the date fixed for redemption to such Holders
of Securities of such series at their last addresses as they shall appear upon the Security register. Any notice which is given in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives
the notice. Failure to give notice or any defect in the notice to the Holder of any Security of a series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Security of
such series. 
 The notice of redemption to each such Holder shall specify the principal amount of each Security of such series held by such
Holder to be redeemed, the date fixed for redemption, the redemption price, the place or places of payment, that payment will be made upon presentation and surrender of such Securities, that such redemption is pursuant to the mandatory or optional
sinking fund, or both, if such be the case, that interest accrued to the date fixed for redemption will be paid as specified in such notice and that on and after said date interest thereon or on the portions thereof to be redeemed will cease to
accrue and shall also specify, if applicable, the conversion price then in effect and the date on which the right to convert such Securities or the portions thereof to be redeemed will expire. In case any Security of a series is to be redeemed in
part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the date fixed for redemption, upon surrender of such Security, a new Security or Securities of such series
in principal amount equal to the unredeemed portion thereof will be issued. 
 The notice of redemption of Securities of any series to be
redeemed at the option of the Issuer shall be given by the Issuer or, at the Issuer’s request, by the Trustee in the name and at the expense of the Issuer. 

  
 39 

 On or before the redemption date specified in the notice of redemption given as provided in this
Section, the Issuer will deposit with the Trustee or with one or more paying agents (or, if the Issuer is acting as its own paying agent, set aside, segregate and hold in trust as provided in Section 3.04) an amount of money sufficient to
redeem on the redemption date all the Securities of such series so called for redemption (other than those Securities theretofore surrendered for conversion into Common Stock or any other security of the Issuer in accordance with their terms) at the
appropriate redemption price, together with accrued interest to the date fixed for redemption. If any Security called for redemption is converted pursuant hereto and in accordance with the terms thereof, any money deposited with the Trustee or any
paying agent or so segregated and held in trust for the redemption of such Security shall be paid to the Issuer upon the Issuer’s request, or, if then held by the Issuer, shall be discharged from such trust. The Issuer will deliver to the
Trustee at least 10 days prior to the date the notice required to be delivered to the Holders is to be sent (unless a shorter time period shall be acceptable to the Trustee) an Officer’s Certificate (which need not comply with
Section 11.05) stating the aggregate principal amount of Securities to be redeemed. In case of a redemption at the election of the Issuer prior to the expiration of any restriction on such redemption, the Issuer shall deliver to the Trustee,
prior to the giving of any notice of redemption to Holders pursuant to this Section, an Officer’s Certificate stating that such restriction has been complied with. 

If less than all the Securities of a series are to be redeemed, the Trustee shall select, in such manner as it shall deem appropriate and
fair, Securities of such series to be redeemed in whole or in part. Securities may be redeemed in part in multiples equal to the minimum authorized denomination for Securities of such series or any multiple thereof. The Trustee shall promptly notify
the Issuer in writing of the Securities of such series selected for redemption and, in the case of any Securities of such series selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless
the context otherwise requires, all provisions relating to the redemption of Securities of any series shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which
has been or is to be redeemed. If any Security selected for partial redemption is surrendered for conversion after such selection, the converted portion of such Security shall be deemed (so far as may be possible) to be the portion selected for
redemption. 
 Section 12.03 Payment of Securities Called for Redemption. If notice of redemption has been given as above
provided, the Securities or portions of Securities specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable redemption price, together with interest accrued to the date fixed for
redemption, and on and after said date (unless the Issuer shall default in the payment of such Securities at the redemption price, together with interest accrued to said date) interest on the Securities or portions of Securities so called for
redemption shall cease to accrue, and such Securities shall cease from and after the date fixed for redemption to be convertible into Common Stock or any other security of the Issuer (to the extent otherwise convertible in accordance with their
terms), if applicable, and cease to be entitled to any benefit or security under this Indenture, and except as provided in the paragraph below, the Holders thereof shall have no right in respect of such Securities except the right to receive the
redemption price thereof and unpaid interest to the date fixed for redemption. On presentation and surrender of such Securities at a place of payment specified in said notice, said Securities or the specified portions thereof shall be paid and
redeemed by the Issuer at the applicable redemption price, together with interest accrued thereon to the date fixed for redemption; provided, that payment of interest becoming due on or prior to the date fixed for redemption shall be payable to the
Holders of such Securities registered as such on the relevant record date subject to the terms and provisions of Sections 2.03 and 2.07 hereof. 

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid or duly
provided for, bear interest from the date fixed for redemption at the rate of interest or Yield to Maturity (in the case of an Original Issue Discount Security) borne by such Security and, if applicable, such Security shall remain convertible into
Common Stock or such other security of the Issuer as may be identified until the principal of such Security shall have been paid or duly provided for. 

  
 40 

 Upon presentation of any Security redeemed in part only, the Issuer shall execute and the Trustee
shall authenticate and deliver to or on the order of the Holder thereof, at the expense of the Issuer, a new Security or Securities of such series, of authorized denominations, in principal amount equal to the unredeemed portion of the Security so
presented. 
 Section 12.04 Exclusion of Certain Securities from Eligibility for Selection for Redemption. Securities
shall be excluded from eligibility for selection for redemption if they are identified by registration and certificate number in an Officer’s Certificate delivered to the Trustee at least 40 days prior to the last date on which notice of
redemption may be given as being owned of record and beneficially by, and not pledged or hypothecated by either (a) the Issuer or (b) an entity specifically identified in such written statement as directly or indirectly controlling or
controlled by or under direct or indirect common control with the Issuer. 
 Section 12.05 Mandatory and Optional Sinking
Funds. The minimum amount of any sinking fund payment provided for by the terms of the Securities of any series is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided
for by the terms of the Securities of any series is herein referred to as an “optional sinking fund payment”. The date on which a sinking fund payment is to be made is herein referred to as the “sinking fund payment date”. 

In lieu of making all or any part of any mandatory sinking fund payment with respect to any series of Securities in cash, the Issuer may at
its option (a) deliver to the Trustee Securities of such series theretofore purchased or otherwise acquired (except upon redemption pursuant to the mandatory sinking fund) by the Issuer or receive credit for Securities of such series (not
previously so credited) theretofore purchased or otherwise acquired (except as aforesaid) by the Issuer and delivered to the Trustee for cancellation pursuant to Section 2.10 and, if applicable, receive credit for Securities (not previously so
credited) converted into Common Stock or any other security of the Issuer and so delivered to the Trustee for cancellation, (b) receive credit for optional sinking fund payments (not previously so credited) made pursuant to this Section, or
(c) receive credit for Securities of such series (not previously so credited) redeemed by the Issuer through any optional redemption provision contained in the terms of such series. Securities so delivered or credited shall be received or
credited by the Trustee at the sinking fund redemption price specified in such Securities. 
 On or before the 60th day next preceding each
sinking fund payment date for any series, the Issuer will deliver to the Trustee an Officer’s Certificate (which need not contain the statements required by Section 11.05) (a) specifying the portion of the mandatory sinking fund
payment to be satisfied by payment of cash and the portion to be satisfied by credit of Securities of such series and the basis for such credit, (b) stating that none of the Securities of such series for which credit will be taken has
theretofore been so credited, (c) stating that no defaults in the payment of interest or Events of Default with respect to such series have occurred (which have not been waived or cured) and are continuing and (d) stating whether or not
the Issuer intends to exercise its right to make an optional sinking fund payment with respect to such series and, if so, specifying the amount of such optional sinking fund payment which the Issuer intends to pay on or before the next succeeding
sinking fund payment date. Any Securities of such series to be credited and required to be delivered to the Trustee in order for the Issuer to be entitled to credit therefor as aforesaid which have not theretofore been delivered to the Trustee shall
be delivered for cancellation pursuant to Section 2.10 to the Trustee with such Officer’s Certificate (or reasonably promptly thereafter if acceptable to the Trustee). Such Officer’s Certificate shall be irrevocable and upon its
receipt by the Trustee the Issuer shall become unconditionally obligated to make all the cash payments or payments therein referred to, if any, on or before the next succeeding sinking fund payment date. Failure of the Issuer, on or before any such
60th day, to deliver such Officer’s Certificate and Securities specified in this paragraph, if any, shall not constitute a default but shall constitute, on and as of such date, the irrevocable election of the Issuer that the mandatory sinking
fund payment for such series due on the next succeeding sinking fund payment date shall be paid entirely in cash without the option to deliver or credit Securities of such series in respect thereof.

 If the sinking fund payment or payments (mandatory or optional or both) to be made in cash on the
next succeeding sinking fund payment date plus any unused balance of any preceding sinking fund payments made in cash shall exceed $[        ] (or the equivalent thereof in any Foreign Currency or a
lesser sum in Dollars or in any Foreign Currency if the Issuer shall so request) with respect to the Securities of any particular series, such cash shall be applied on the next succeeding sinking fund payment date to the redemption of Securities of
such series at the sinking fund redemption price together with accrued interest to the date fixed for redemption. If such amount shall be $[        ] (or the equivalent thereof in any Foreign Currency)
or less and the Issuer makes no such request then it shall be carried over until a sum in excess of $[        ] (or the equivalent thereof in any Foreign Currency) is available, which delay in
accordance with this paragraph shall not be a default or breach of the obligation to make such payment. The Trustee shall select, in the manner provided in Section 12.02, for redemption on such sinking fund payment date a sufficient principal
amount of Securities of such series to which such cash may be applied, as nearly as may be, and shall (if requested in writing by the Issuer) inform the Issuer of the serial numbers of the Securities of such series (or portions thereof) so selected.
The Trustee, in the name and at the expense of the Issuer (or the Issuer, if it shall so request the Trustee in writing), shall cause notice of redemption of the Securities of such series to be given in substantially the manner provided in
Section 12.02 (and with the effect provided in Section 12.03) for the redemption of Securities of such series in part at the option of the Issuer. The amount of any sinking fund payments not so applied or allocated to the redemption of
Securities of such series shall be added to the next cash sinking fund payment for such series and, together with such payment, shall be applied in accordance with the provisions of this Section. Any and all sinking fund moneys held on the stated
maturity date of the Securities of any particular series (or earlier, if such maturity is accelerated), which are not held for the payment or redemption of particular Securities of such series, shall be applied, together with other moneys, if
necessary, sufficient for the purpose, to the payment of the principal of, and interest on, the Securities of such series at maturity. The Issuer’s obligation to make a mandatory or optional sinking fund payment shall automatically be reduced
by an amount equal to the sinking fund redemption price allocable to any Securities or portions thereof called for redemption pursuant to the preceding paragraph on any sinking fund payment date and converted into Common Stock or any other security
of the Issuer in accordance with the terms of such Securities; provided that, if the Trustee is not the conversion agent for the Securities, the Issuer or such conversion agent shall give the Trustee written notice on or prior to the date fixed for
redemption of the principal amount of Securities or portions thereof so converted. 
 On or before each sinking fund payment date, the
Issuer shall pay to the Trustee in cash or shall otherwise provide for the payment of all interest accrued to the date fixed for redemption on Securities to be redeemed on such sinking fund payment date. 

The Trustee shall not redeem or cause to be redeemed any Securities of a series with sinking fund moneys or give any notice of redemption of
Securities for such series by operation of the sinking fund during the continuance of a default in payment of interest on such Securities or of any Event of Default except that, where the mailing of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall redeem or cause to be redeemed such Securities, provided that it shall have received from the Issuer a sum sufficient for such redemption. Except as aforesaid, any moneys in the sinking fund for such
series at the time when any such default or Event of Default shall occur, and any moneys thereafter paid into the sinking fund, shall, during the continuance of such default or Event of Default, be deemed to have been collected under Article 5 and
held for the payment of all such Securities. In case such Event of Default shall have been waived as provided in Section 5.10, or the default cured on or before the 60th day preceding the sinking fund payment date in any year, such moneys shall
thereafter be applied on such sinking fund payment date in accordance with this Section to the redemption of such Securities.
