Exhibit 4.4
DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES
EXCHANGE ACT OF 1934
As of June 30, 2021, Ubiquiti Inc. (“we”, “our”, “us” or the “Company”) has its common stock, $0.001 par value per share (“common stock”) registered under Section 12 of the Securities Exchange Act of 1934, as amended. 
The following description of our common stock, which is not complete and is subject to, and qualified in its entirety by reference to, our third amended and restated certificate of incorporation and amended and restated bylaws, each of which is filed or incorporated by reference as an exhibit to our Annual Report on Form 10-K of which this Exhibit is a part, and the Delaware General Corporation Law (“DGCL”). You should read our third amended and restated certificate of incorporation and amended and restated bylaws and the applicable provisions of the DGCL for a complete statement of the provisions described under the caption “Common Stock” and for other provisions that may be important to you. 
Common Stock 
Our authorized capital stock under our third amended and restated certificate of incorporation consists of 500,000,000 shares of common stock, par value $0.001 per share.  As of August 25, 2021, there were 62,499,344 shares of our common stock outstanding. As of such date there were 10,525 shares of common stock subject to outstanding options and 50,877 shares of common stock subject to outstanding RSUs. 
Holders of our common stock are entitled to one vote for each share of common stock held of record for the election of directors and on all matters submitted to a vote of stockholders. Holders of our common stock are entitled to receive dividends ratably, if any, as may be declared by our board of directors out of legally available funds, subject to any preferential dividend rights of any preferred stock then outstanding. Upon our dissolution, liquidation or winding up, holders of our common stock are entitled to share ratably in our net assets legally available after the payment of all our debts and other liabilities, subject to the preferential rights of any preferred stock then outstanding. Holders of our common stock have no preemptive, subscription, redemption or conversion rights. The rights, preferences and privileges of holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future. All of our outstanding shares of common stock are fully paid and nonassessable. 
Preferred Stock 
Our authorized capital stock consists of 50,000,000 shares of preferred stock, par value $0.001 per share. As of August 25, 2021, there were no shares of our preferred stock outstanding. Our board of directors has the authority, without further vote or action by the stockholders, to issue from time to time shares of preferred stock in one or more series and to fix or alter the designations, powers, preferences and rights, and the qualifications, limitations or restrictions of the shares of each such series of preferred stock, including the dividend rights, dividend rates, conversion rights, voting rights, rights and terms of redemption (including sinking fund provisions), redemption price or prices, liquidation preferences and the number of shares constituting any series or designations of such series, any or all of which may be greater than the rights of common stock. The issuance of preferred stock could adversely affect the voting power of holders of our common stock and the likelihood that holders of our common stock will receive dividend payments and payments upon liquidation and could have the effect of delaying, deferring or preventing a change in control. 
Registration Rights 
Certain holders of shares of our common stock, including but not limited to 56,278,181 shares of our common stock held by our chief executive officer, have the registration rights set forth below with respect to registration of the resale of such shares under the Securities Act of 1933, as amended (the “Securities Act”) pursuant to a registration agreement by and among us and certain of our stockholders. As applicable, we refer to these shares collectively as “registrable securities.” 
Long-form demand registration rights. At any time the holders of at least a majority of the outstanding registrable securities that were issued upon conversion of our Series A preferred stock in our initial public offering may demand that we effect a registration under the Securities Act on Form S-1 covering the public offering and sale of all or part of the registrable securities held by such stockholders, provided that the value of the registrable securities that such holders propose to sell in such offering is at least $25.0 million. Upon any such demand, we must use our commercially reasonable efforts to effect the registration of the registrable securities which we have been requested to register together with all other registrable securities that we may have been requested to register by other stockholders pursuant to the incidental registration rights described below. We are only obligated to effect two registrations in response to these demand registration rights for the holders of the registrable 

securities. We may defer any such registration for up to 120 days if our board of directors reasonably determines such registration would reasonably be expected to have a material adverse effect on a transaction we plan or propose to engage in. 
Short form registration rights. At any time after we qualified to file a registration statement on Form S-3, the holders of a majority of the outstanding registrable securities that were issued upon conversion of our Series A preferred stock in our initial public offering may request in writing that we effect a registration on Form S-3, provided that the value of the registrable securities that such holders propose to sell in such offering is at least $5.0 million, subject to certain exceptions. We are obligated to file up to two registration statements on Form S-3 in any 12-month period. 
Incidental registration rights. If we register any of our securities for public sale, including pursuant to any stockholder initiated demand registration, holders of the registrable securities will have the right to include their shares in the registration statement, subject to certain exceptions relating to employee benefit plans and mergers and acquisitions. The underwriters of any underwritten offering will have the right to limit the number of registrable securities to be included in the registration statement on a pro rata basis, subject to certain restrictions. 
Expenses of registration. We will pay all registration expenses related to any long-form demand, short-form demand or incidental registration other than underwriting discounts and selling commissions which will be borne by the holders of the registrable securities. 
Indemnification. The registration agreement contains indemnification provisions pursuant to which we are obligated to indemnify the selling stockholders, underwriters and certain of their affiliates in the event of material misstatements or omissions in the registration statement or related violations of federal and state securities law by us. As a condition to including their securities in any registration statement filed pursuant to demand or incidental registration rights, we may require the selling stockholders to agree to indemnify us for misstatements or omissions attributable to them. 
Anti-takeover Effects of Delaware Law and our Certificate of Incorporation and Bylaws 
Our third amended and restated certificate of incorporation and our amended and restated bylaws contain certain provisions that could have the effect of delaying, deferring or discouraging another party from acquiring control of us. We expect these provisions and certain provisions of Delaware law, which are summarized below, to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed, in part, to encourage persons seeking to acquire control of us to negotiate first with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate more favorable terms with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us. 
Undesignated preferred stock. As discussed above, our board of directors has the ability to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of our company. 
Limits on the ability of stockholders to act by written consent or call a special meeting. Our third amended and restated certificate of incorporation provides that our stockholders may not act by written consent, which may lengthen the amount of time required to take stockholder actions. As a result, a holder controlling a majority of our capital stock would not be able to amend our certificate of incorporation or bylaws or remove directors without holding a meeting of our stockholders called in accordance with our bylaws. 
In addition, our third amended and restated certificate of incorporation and amended and restated bylaws provide that special meetings of the stockholders may be called only by the board of directors acting pursuant to a resolution adopted by a majority of the total authorized directors, the chairperson of our board of directors, our chief executive officer (or in the absence of the chief executive officer, the president) or a majority of our board of directors. Stockholders may not call a special meeting, which may delay the ability of our stockholders to force consideration of a proposal or for holders controlling a majority of our capital stock to take any action, including the removal of directors. 
Requirements for advance notification of stockholder nominations and proposals. Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of our board of directors. These provisions may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed. These provisions may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company. 
Board classification. Our third amended and restated certificate of incorporation provides that our board of directors will be divided into three classes, one class of which is elected each year by our stockholders. The directors in each class will serve 

for a three-year term. Our classified board of directors may discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for stockholders to replace a majority of the directors. 
Election and removal of directors. Our third amended and restated certificate of incorporation and amended and restated bylaws contain provisions that establish specific procedures for appointing and removing members of our board of directors. Under our third amended and restated certificate of incorporation and amended and restated bylaws, vacancies and newly created directorships on our board of directors may be filled only by a majority of the directors then serving on the board of directors. Under our third amended and restated certificate of incorporation and amended and restated bylaws, directors may be removed only for cause. 
No cumulative voting. The Delaware General Corporation Law provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless our restated certificate of incorporation provides otherwise. Our third amended and restated certificate of incorporation and amended and restated bylaws do not expressly provide for cumulative voting. Without cumulative voting, a minority stockholder may not be able to gain as many seats on our board of directors as the stockholder would be able to gain if cumulative voting were permitted. The absence of cumulative voting makes it more difficult for a minority stockholder to gain a seat on our board of directors to influence our board of directors’ decision regarding a takeover. 
Delaware anti-takeover statute. We are subject to the provisions of Section 203 of the Delaware General Corporation Law regulating corporate takeovers. In general, Section 203 prohibits a publicly held Delaware corporation from engaging, under certain circumstances, in a business combination with an interested stockholder for a period of three years following the date the person became an interested stockholder unless: 
 
												
	 	•	 	prior to the date of the transaction, our board of directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

												
	 	•	 	upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, calculated as provided under Section 203; or
		•	 	at or subsequent to the date of the transaction, the business combination is approved by our board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.

Generally, a business combination includes a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. An interested stockholder is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting stock. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate that Section 203 may discourage attempts that might result in a premium over the market price for the shares of common stock held by stockholders. 
The provisions of Delaware law and the provisions of our third amended and restated certificate of incorporation and amended and restated bylaws, could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they might also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions might also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders might otherwise deem to be in their best interests.

The transfer agent and registrar for our common stock is Computershare Trust Co., N.A. The transfer agent’s address is 462 S 4th Street, Suite 1600, Louisville, KY 4020 and its telephone number is (877) 373-6374.

Lease shall be the period specified in Section 1.2 hereof as the “Lease Term,” unless sooner terminated or extended as herein provided. The Commencement Date shall be the date on which Landlord’s Work is Substantially
Complete (as said terms are hereinafter defined). Landlord’s Work shall be deemed to be “Substantially Complete” on the date that all Landlord’s Work has been performed, other than any details of construction, mechanical
adjustment or any other similar matter, the non-completion of which does not materially interfere with Tenant’s use of the Premises (so called “punch-list” items) provided that Landlord will
thereafter diligently pursue the completion of the punch-list items. If Landlord is delayed in the performance of Landlord’s Work as a result of the acts or omissions of Tenant or any Tenant Party, including, without limitation,
(i) changes requested by Tenant to approved plans, (ii) Tenant’s failure to comply with any of its obligations under this Lease, or (iii) the specification of any materials or equipment with long lead times for which Tenant was
notified in advance that such specification would result in a delay in the performance of Landlord’s Work (a “Tenant Delay”), Landlord’s Work shall be deemed to be Substantially Complete on the date that Landlord could
reasonably have been expected to Substantially Complete Landlord’s Work absent any Tenant Delay.

“as-is” condition and configuration without any representations or warranties by Landlord. By taking possession of the Premises, Tenant agrees that the Premises are in good order and satisfactory
condition, provided that within [***] of taking possession of the Premises Tenant may provide Landlord with a list of any incomplete items or defects that Tenant has discovered in Landlord’s Work, and Landlord shall diligently pursue the cure
or completion of such items or defects. Landlord shall not be liable for a failure to deliver possession of the Premises or any other space due to the holdover or unlawful possession of such space by another party; provided, however, that Landlord

 After Landlord determines that Landlord’s Work has sufficiently progressed to the point
where permitting Tenant to enter the Premises will not adversely affect the timely completion of or the cost of completion of the remaining elements of Landlord’s Work, then Landlord will permit Tenant and Tenant’s contractor to enter the
Premises for the limited purpose of moving in and installing Tenant’s equipment and furniture, installing Tenant’s phone and data/computer wiring and cabling. Any such early entry shall be at Tenant’s sole risk and expense, and
Landlord shall have no liabilities or obligations to Tenant in connection therewith, including any liability for damage or injury to persons or property in connection therewith. Prior to such entry, Tenant shall obtain and submit to Landlord all
insurance coverages required pursuant to this Lease. Upon such entry, Tenant shall be bound by and shall comply with all provisions of the Lease (excluding the payment of any Annual Fixed Rent), including, without limitation, the provisions of the
Lease regarding the performance of alterations, improvements and installations in the Premises, notwithstanding that the Commencement Date may not yet have occurred. Without limitation, all of such work performed by Tenant in the Premises prior to
the Commencement Date shall be coordinated with any work being performed by Landlord so as not to delay the completion of Landlord’s Work. 

In the event Tenant desires any improvements be made to the Premises, in addition to the aforementioned Landlord’s Work, and additional
improvements shall be performed at Tenant’s sole cost and expense in accordance with the terms of the Lease, including, without limitation, Article VIII hereof.

Landlord is prevented or delayed from making any repairs, alterations or improvements, or furnishing any services or performing any other covenant or duty to be performed on Landlord’s part, by reason of any cause reasonably beyond
Landlord’s control, or for any cause due to any act or neglect of Tenant or Tenant’s servants, agents, employees, licensees or any person claiming by, through or under Tenant, Landlord shall not be liable to Tenant therefor, nor shall
Tenant be entitled to any abatement or reduction of rent by reason thereof (except as expressly set forth herein), or right to terminate this Lease, nor shall the same give rise to a claim in Tenant’s favor that such failure constitutes actual
or constructive, total or partial, eviction from the Premises. 
 Landlord reserves the right to stop any service or utility system, when
necessary by reason of accident or emergency, or until necessary repairs have been completed; provided, however, that in each instance of stoppage, Landlord shall exercise reasonable diligence to eliminate the cause thereof. Except in case of
emergency repairs, Landlord will give Tenant reasonable advance notice of any contemplated stoppage and will use reasonable efforts to avoid unnecessary inconvenience to Tenant by reason thereof. 

Notwithstanding anything to the contrary in this Lease contained, if due to Landlord’s default, the Premises shall lack any service which
Landlord is required to provide hereunder (thereby rendering the Premises or a portion thereof untenantable) (a “Service Interruption”) so that, for the Landlord Service Interruption Cure Period, as hereinafter defined, the
continued operation in the ordinary course of Tenant’s business is materially adversely affected as a direct result of such lack of service, then, provided that Tenant ceases to use the affected portion of the Premises during the entirety of
the Landlord Service Interruption Cure Period and that such untenantability and Landlord’s inability to cure such condition is not caused by the fault or neglect of Tenant or Tenant’s agents, employees or contractors, Fixed Rent shall
thereafter be abated in proportion to such untenantability until such condition is cured sufficiently to allow Tenant to occupy the affected portion of the Premises. For the purposes hereof, the “Landlord Service Interruption Cure
Period” shall be defined as [***] after Landlord’s receipt of written notice from Tenant of the condition causing untenantability in the Premises. The provisions of this paragraph shall not apply in the event of untenantability caused
by fire or other casualty, or taking. The remedies set forth in this paragraph shall be Tenant’s sole remedies in the event of a Service Interruption.

expense. Tenant may install, at Tenant’s sole cost and expense, signage identifying Tenant on the entrance door to the Premises and/or within the Premises, which signage shall be subject to Landlord’s prior approval (such approval not to
be unreasonably withheld or delayed) so long as such signage is consistent with other tenant signage in the Office Area.

Landlord Party. The Landlord Parties shall not be bound by any compromise or settlement of any such claim, action or proceeding without the prior written consent of such Landlord Parties. 

11.2 Tenant’s Risk 

Tenant agrees to use and occupy the Premises, and to use such other portions of the Office Area and the Project as Tenant is given the right
to use by this Lease at Tenant’s own risk. Except to the extent caused by the negligence or willful misconduct of Landlord or any of the Landlord Parties, the Landlord Parties shall not be liable to the Tenant Parties for any damage, injury,
loss, compensation, or claim (including, but not limited to, claims for the interruption of or loss to a Tenant Party’s business) based on, arising out of or resulting from any cause whatsoever, including, but not limited to, repairs to any
portion of the Premises or the Office Area or the Project, any fire, robbery, theft, mysterious disappearance, or any other crime or casualty, the actions of any other tenants of the Office Area or of any other person or persons, or any leakage in
any part or portion of the Premises or the Office Area or the Project, or from water, rain or snow that may leak into, or flow from any part of the Premises or the Office Area or the Project, or from drains, pipes or plumbing fixtures in the Office
Area or the Project. Any goods, property or personal effects stored or placed in or about the Premises shall be at the sole risk of the Tenant Party, and neither the Landlord Parties nor their insurers shall in any manner be held responsible
therefor. The Landlord Parties shall not be responsible or liable to a Tenant Party, or to those claiming by, through or under a Tenant Party, for any loss or damage that may be occasioned by or through the acts or omissions of persons occupying
adjoining premises or any part of the premises adjacent to or connecting with the Premises or any part of the Office Area or otherwise.

 11.3 Tenant’s Insurance 

(a) Tenant agrees to maintain in full force on or before the earlier of (i) the date on which any Tenant Party first enters the Premises
for any reason or (ii) the Commencement Date, and thereafter throughout and until the end of the Lease Term, and after the end of the Lease Term for so long as Tenant or anyone acting by, through or under Tenant is in occupancy of the
Premises or any portion thereafter, a policy of commercial general liability insurance, on an occurrence basis, issued on a form at least as broad as Insurance Services Office (“ISO”) Commercial General Liability Coverage
“occurrence” form CG 00 01 10 01 or another Commercial General Liability “occurrence” form providing equivalent coverage. Such insurance shall include broad form contractual liability coverage, specifically covering but not
limited to the indemnification obligations undertaken by Tenant in this Lease. The minimum limits of liability of such insurance shall be [***] per occurrence. In addition, in the event Tenant hosts a function in the Premises, Tenant agrees to
obtain, and cause any persons or parties providing services for such function to obtain, the appropriate insurance coverages as determined by Landlord (including liquor liability coverage, if applicable) and provide Landlord with evidence of the
same. 
 (b) Tenant shall maintain at all times during the Term of the Lease, and during such earlier time as Tenant may be performing work
in or to the Premises or have property, fixtures, furniture, equipment, machinery, goods, supplies, wares or merchandise on the Premises, and containing thereafter so long as the Tenant is in occupancy of any part of the Premises, business
interruption insurance and insurance against loss or damage covered by the so-called “all risk” type insurance coverage with respect to Tenant’s property, fixtures, furniture, equipment,
machinery, goods, supplies, wares and merchandise, and all alterations, improvements and other modifications made by or on behalf of the Tenant in the Premises, and other property of Tenant located at the Premises, which are permitted to be removed
by Tenant at the expiration or earlier termination of the Lease Term except to the extent paid for by Landlord (collectively “Tenant’s Property”). The business interruption insurance required by this Section 11.4 shall be
in minimum amounts typically carried by prudent tenants engaged in similar operations, but in no event shall be in an amount less than the Annual Fixed Rent then in effect during any Lease Year, plus any Additional Rent due and payable for the
immediately preceding Lease Year. The “all risk” insurance required by this section shall be in an amount at least equal to the full replacement cost of Tenant’s Property. In addition, during such time as Tenant is performing work in
or to the Premises. Tenant, at Tenant’s expense, shall also maintain, or shall cause its contractor(s) to maintain, builder’s risk insurance for the full insurable value of such work. Landlord and such additional persons or entities as
Landlord may reasonably request shall be named as loss payees, as their interests may appear, on the policy or policies required by this Lease. In the event of loss or damage covered by the “all risk” insurance required by this Lease, the
responsibilities for repairing or restoring the loss or damage shall be determined in accordance with Article XII. To the extent that Landlord is obligated to pay for the repair or restoration of the loss or damage covered by the policy, Landlord
shall be paid the proceeds of the “all risk” insurance covering the loss or damage. To the extent Tenant is obligated to pay for the repair or restoration of the loss or damage, covered by the policy, Tenant shall be paid the proceeds of
the “all risk” insurance covering the loss or damage. If both Landlord and Tenant are obligated to pay for the repair or restoration of the loss or damage covered by the policy, the insurance proceeds shall be paid to each of them in the
pro rata proportion of their obligations to repair or restore the loss or damage. If the loss or damage is not repaired or restored (for example, if the Lease is terminated pursuant to Article XII), the insurance proceeds shall be paid to Landlord
and Tenant in the pro rata proportion of their relative contributions to the cost of the leasehold improvements covered by the policy. 

  
 17 

 (c) Tenant agrees to maintain in full force on or before the earlier of (i) the
date on which any Tenant Party first enters the Premises for any reason or (ii) the Commencement Date, and thereafter throughout the end of the Term, and after the end of the Term for so long after the end of the Term as Tenant or anyone
acting by, through or under Tenant is in occupancy of the Premises or any portion thereafter, (1) worker’s compensation insurance; and (2) employer’s liability insurance. Such worker’s compensation insurance shall
carry minimum limits as defined by the law of the jurisdiction in which the Premises are located (as the same may be amended from time to time). Such employer’s liability insurance shall be in an amount not less than [***] for each accident,
[***] disease-policy limit, and [***] disease-each employee. 
 11.4 Requirements for Tenant’s Insurance 

All insurance required to be maintained by Tenant pursuant to this Lease shall be maintained with responsible companies that are admitted to
do business, and are in good standing in the Commonwealth of Massachusetts and that have a rating of at least “A” and are within a financial size category of not less than “Class X” in the most current Best’s Key Rating
Guide or such similar rating as may be reasonable selected by Landlord. All such insurance shall: (1) be acceptable in form and content to Landlord; (2) be primary and noncontributory; and (3) contain an endorsement prohibiting
cancellation, failure to renew, reduction of amount of insurance, or charge in coverage without the insurer first giving Landlord [***] prior written notice (by certified or registered mail, return receipt requested, or by fax or email) of such
proposed action. No such policy shall contain any deductible or self-insured retention greater than [***]. Such deductibles and self-insured retentions shall be deemed to be “insurance” for purpose of the waiver in Section [__] below. In
the event Tenant shall fail to obtain or maintain any insurance meeting the requirements of this Article, or to deliver such policies or certificates as required by this Article, Landlord may, at its option, on [***] notice to Tenant, procure such
policies for the account of Tenant, and the cost thereof shall be paid to Landlord within [***] after deliver to Tenant of bills therefor. 

11.5 Additional Insured 

The commercial general liability insurance carried by Tenant pursuant to this Lease, and any additional liability insurance carried by Tenant
pursuant to Section 11.3 of this Lease, shall name Landlord, Landlord’s managing agent, and such other Persons as Landlord may reasonably request from time to time as additional insureds with respect to liability arising out of or related
to this Lease or the operations of Tenant (collectively “Additional Insureds”). Such insurance shall provide primary coverage without contribution from any other insurance carried by or for the benefit of Landlord, Landlord’s
managing agent, or other Additional Insureds. Such insurance shall also waive any right of subrogation against each Additional Insured. 

  
 18 

 11.6 Certificates of Insurance 

On or before the earlier of (i) the date on which any Tenant Party first enters the Premises for any reason or (ii) the Commencement
Date, Tenant shall furnish Landlord with certificates evidencing the insurance coverage required by this Lease, and renewal certificates shall be furnished to Landlord at least annually thereafter, and at least [***] prior to the expiration date of
each policy for which a certificate was furnished. Failure by the Tenant to provide the certificates or letters required by this Section 11.6 shall not be deemed to be a waiver of the requirements in this Section 11.6. Upon request by
Landlord, a true and complete copy of any insurance policy required by this Lease shall be delivered to Landlord within [***] following Landlord’s request. 

11.7 No Violation of Building Policies 

Tenant shall not commit or permit any violation of the policies of fire, boiler, sprinkler, water damage or other insurance covering the
Project and/or the fixtures, equipment and property therein carried by Landlord, or do or permit anything to be done, or keep or permit anything to be kept, in the Premises, which in case of an} of the foregoing (i) would result in termination
of any such policies, (ii) would adversely affect Landlord’s right of recovery under any of such policies, or (iii) would result in reputable and independent insurance companies refusing to insure the Project or the property of
Landlord in amounts reasonably satisfactory to Landlord. 
 11.8 Tenant to Pay Premium Increases 

If, because of anything done, causes or permitted to be done, or omitted by Tenant ( or its subtenant or other occupants of the Premises), the
rates for liability, fire, boiler, sprinkler, water damage or other insurance on the Project and equipment of Landlord shall be higher than they otherwise would be, Tenant shall reimburse Landlord upon demand for the additional insurance premiums
thereafter paid by Landlord because of the aforesaid reasons. 
 11.9 Waiver of Subrogation 

The parties hereto waive and release any and all rights of recovery against the other, and the other or to make any claim against the other,
and in the case of Landlord, against all “Tenant Parties” (hereinafter defined), and in the case of Tenant, against all “Landlord Parties” (hereinafter defined, for any loss or damage incurred by the waiving/releasing party to
the extent such loss or damage is insured under any insurance policy required by this Lease or which would have been so insured had the party carried the insurance it was required to carry hereunder. Tenant shall obtain from its subtenants and other
occupants of the Premises a similar waiver and release of claims against any or all of Tenant or Landlord. In addition, the parties hereto (and in the case of Tenant, its subtenants and other occupants of the Premises) shall procure an appropriate
clause in, or endorsement on, any insurance policy required by this Lease pursuant to which the insurance company waives subrogation. The insurance policies required by this Lease shall contain no provision that would invalidate or restrict the
parties’ waiver and release of the rights of recovery in this section. The parties hereto covenant that no insurer shall hold any right of subrogation against the parties hereto by virtue of such insurance policy. 

The term “Landlord Party” or “Landlord Parties” shall mean Landlord, any affiliate of Landlord,
Landlord’s managing agents for the Office Area, each mortgagee (if any), each ground lessor (if any), and each of their respective direct or indirect partners, officers, shareholders, directors, members, trustees, beneficiaries, servants,
employees, principals, contractors, licensees, agents or representatives. For the purposes of this Lease, the term “Tenant Party” or “Tenant Parties” shall mean Tenant, any affiliate of Tenant, any
permitted subtenant or any other permitted occupant of the Premises, and each of their respective direct or indirect partners, officers, shareholders, directors, members, trustees, beneficiaries, servants, employees, principals, contractors,
licensees, agents, invitees or representatives. 

  
 19 

 11.10 Tenant s Work 

During such times as Tenant is performing work or having work or services performed in or to the Premises, Tenant shall require its
contractors, and their subcontractors of all tiers, to obtain and maintain commercial general liability, automobile, workers compensation, employer’s liability, builder’s risk, and equipment/property insurance in such amounts and on such
terms as are reasonably satisfactory to Landlord. Such insurance shall also waive any right of subrogation against each Additional Insured. Tenant shall obtain and submit to Landlord, prior to the earlier of (i) the entry onto the Premises by
such contractors or subcontractors or (ii) commencement of the work or services, certificates of insurance evidencing compliance with the requirements of this section. 

11.11 Landlord’s Indemnity 

To the maximum extent permitted by law and subject to Section 11.9 above, except to the extent arising or resulting from the negligence
or willful misconduct of any Tenant Party, Landlord agrees to indemnify and save harmless the Tenant Parties from and against all claims of whatever nature arising from or claimed to have arisen from any accident, injury or damage whatsoever
occurring, where such accident, injury or damage results from any negligence or willful misconduct on the part of any Landlord Party. 

11.12 Landlord’s Insurance 

Landlord shall maintain insurance against loss or damage with respect to the Office Area on an “all risk” type insurance form, with
customary exceptions, subject to such deductibles as Landlord may determine, in an amount equal to at least the replacement value of the Office Area. Landlord shall also maintain such instance with respect to any improvements, alterations, and
fixtures of Tenant located at the Premises to the extent paid for by Landlord. Such insurance shall be maintained with an insurance company selected by Landlord. Payment for losses thereunder shall be made solely to Landlord. Any or all of
Landlord’s insurance may be provided by blanket coverage maintained by Landlord or any affiliate of Landlord under its insurance program for its portfolio of properties, or by Landlord or any affiliate of Landlord under a program of
self-insurance. Landlord shall not be obligated to insure, and shall not assume any liability of risk of loss for, Tenant’s Property, including any such property or work of Tenant’s subtenants or occupants. Landlord will also have no
obligation to carry insurance against, nor be responsible for, any loss suffered by Tenant, subtenants or other occupants due to interruption of Tenant’s or any subtenant’s or occupant’s business.

 ARTICLE XII. 

FIRE, CASUALTY AND TAKING 
 12.1
Damage Resulting from Casualty 
 If all or any portion of the Premises becomes untenantable by fire or other casualty to the
Premises (collectively a “Casualty”), Landlord, with reasonable promptness, shall provide Tenant with a good faith written estimate of the amount of time required using standard working methods to substantially complete the
repair and restoration of the Premises and any portion of the Office Area necessary to provide access to the Premises. If such estimate indicates that the Premises or any portion of the Office Area necessary to provide access to the Premises cannot
be made tenantable within [***] from the date the repair is started, then either party shall have the right to terminate this Lease upon written notice to the other within [***] after receipt of the estimate. Tenant, however, shall not have the
right to terminate this Lease if the Casualty was caused by the negligence or intentional misconduct of Tenant or any Tenant Parties. In addition, Landlord, by notice to Tenant within [***] after the date of the Casualty, shall have the right to
terminate this Lease if: (1) the Premises have been materially damaged and there is less than two (2) years of the Term remaining on the date of the Casualty; (2) any mortgagee requires that the insurance proceeds be applied to the
payment of the mortgage debt; or (3) a material uninsured loss to the Office Area occurs. 
 If this Lease is not terminated, Landlord
shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, restore the Premises and any portion of the Office Area necessary to provide access to the Premises.
Such restoration shall be substantially the same condition that existed prior to the Casualty, except for modifications required by Legal Requirements or any other modifications to the common areas deemed desired by the Landlord. Upon notice from
Landlord, Tenant shall assign to Landlord (or to any party designated by Landlord) all property insurance proceeds payable to Tenant under Tenant’s insurance with respect to any alterations, improvements or installations performed by or for the
benefit of Tenant; provided if the estimated cost to repair such alterations, improvements or installations exceeds the amount of insurance proceeds received by Landlord from Tenant’s insurance carrier, the excess cost of such repairs shall be
paid by Tenant to Landlord prior to Landlord’s commencement of repairs. Within [***] of demand, Tenant shall also pay Landlord for any additional excess costs that are determined during the performance of the repairs. Landlord shall not be
liable for any inconvenience to Tenant, or injury to Tenant’s business resulting in any way from the Casualty or the repair thereof. Provided that there exists no Event of Default, during any period of time that all or a material portion of the
Premises is rendered untenantable as a result of a Casualty, the Rent shall abate for the portion of the Premises that is untenantable and not used by Tenant. 

  
 21 

 12.2 Taking 

Either party may terminate this Lease if any material part of the Premises is taken or condemned for any public or quasi-public use under
Legal Requirements, by eminent domain or private purchase in lieu thereof (a “Taking”). Landlord shall also have the right to terminate this Lease if there is a Taking of any portion of the Building or Property which would have a
material adverse effect on Landlord’s ability to profitably operate the remainder of the Building. The terminating party shall provide written notice of termination to the other party within [***] after it first receives notice of the Taking.
The termination shall be effective on the date the physical taking occurs. If this Lease is not terminated, Fixed Rent shall be appropriately adjusted to account for any reduction in the square footage of the Building or Premises. All compensation
awarded for a Taking shall be the property of Landlord. The right to receive compensation or proceeds is expressly waived by Tenant; however, Tenant may file a separate claim for Tenant’s property and Tenant’s reasonable relocation
expenses, provided the filing of the claim does not diminish the amount of Landlord’s award. If only a part of the Premises is subject to a Taking and this Lease is not terminated, Landlord, with reasonable diligence, will restore the remaining
portion of the Premises as nearly as practicable to the condition immediately prior to the Taking. 
 ARTICLE XIII. 

DEFAULT 
 13.1
Tenant’s Default 
 This Lease and the term of this Lease are subject to the limitation that Tenant shall be in
default if, at any time during the Lease Term any one or more of the following events (here in called an “Event of Default” a “default of Tenant” or similar reference) shall occur and not be cured prior to
the expiration of the grace period (if any) herein provided, as follows: 
 (a) Tenant shall fail to pay any installment of the Annual Fixed
Rent, or any Additional Rent or any other monetary amount due under this Lease on or before the date on which the same becomes due and payable and such default shall continue for [***] after written notice from Landlord; provided that no such notice
shall be required if Tenant has received a similar notice more than two (2) times within three hundred sixty-five (365) days prior to such violation or failure; or 

(b) Tenant shall assign its interest in this Lease or sublet any portion of the Premises in violation of the requirements of Article X of this
Lease; or 
 (c) Tenant shall fail to perform or observe some term or condition of this Lease which, because of its character, would
immediately jeopardize Landlord’s interest (such as, but without limitation, failure to maintain general liability insurance, or the employment of labor and contractors within the Premises which interfere with Landlord’s work, in violation
of Sections 8.2, 9.2 or 9.9 or a failure to observe the requirements of Section 9.2), and such failure continues for [***] after written notice from Landlord to Tenant thereof; or 

(d) Tenant shall fail to perform or observe any other requirement, term, covenant or condition of this Lease (not hereinabove in this
Section 13.1 specifically referred to) on the part of Tenant to be performed or observed and such failure shall continue for thirty (30) days after written notice thereof from Landlord to Tenant, or if said default shall reasonably
require longer than [***] to cure, if Tenant shall fail to commence to cure said default within [***] after notice thereof and/or fail to continuously prosecute the curing of the same to completion with due diligence; or 

(e) The estate hereby created shall be taken on execution or by other process of law; or 

  
 22 

 (f) Tenant becomes insolvent, makes a transfer in fraud of creditors, makes an assignment
for the benefit of creditors, admits in writing its inability to pay its debts when due or forfeits or loses its right to conduct business; or 

(g) Tenant otherwise abandons or vacates the Premises for [***] (other than for purposes of conducting repairs or improvements). 

13.2 Termination; Re-Entry 

Upon the happening of any one or more of the aforementioned Events of Default (notwithstanding any license of a former breach of covenant or
waiver of the benefit hereof or consent in a former instance), Landlord or Landlord’s agents or servants may give to Tenant a notice (hereinafter called “notice of termination”) terminating this Lease on a date specified in
such notice of termination (which shall be not be less than [***] after the date of the mailing of such notice of termination), and this Lease and the Lease Term, as well as any and all of the right, title and interest of the Tenant hereunder, shall
wholly cease and expire on the date set forth in such notice of termination (Tenant hereby waiving any rights of redemption) in the same manner and with the same force and effects as if such date were the date originally specified herein for the
expiration of the Lease Term, and Tenant shall then quit and surrender the Premises to Landlord. 
 In addition or as an alternative to the
giving of such notice of termination, Landlord or Landlord’s agents or servants may, by any suitable action or proceeding at law, immediately or at any time thereafter re-enter the Premises and remove therefrom Tenant, its agents, employees,
servants, licensees, and any subtenants and other persons, and all or any of its property therefrom, and repossess and enjoy the Premises, together with all additions, alterations and improvements thereto; but, in any event under this
Section 13.2, Tenant shall remain liable as hereinafter provided. 
 The words
“re-enter” and “re-entry” as used throughout this Article XIII are not restricted to their technical legal meanings. 

13.3 Continued Liability; Re-Letting 

If this Lease is terminated or if Landlord shall re-enter the Premises as aforesaid, or in the event
of the termination of this Lease, or of re- entry, by or under any proceeding or action or any provision of law by reason of an Event of Default hereunder on the part of Tenant, Tenant covenants and agrees
forthwith to pay and be liable for, on the days originally fixed herein for the payment thereof, amounts equal to the several installments of Annual Fixed Rent, all Additional Rent and other charges reserved as they would, under the terms of this
Lease, become due if this Lease had not been terminated or if Landlord had not entered or re-entered, as aforesaid, and whether the Premises be relet or remain vacant, in whole or in part, or for a period less
than the remainder of the Lease Term, or for the whole thereof, but, in the event the Premises be relet by Landlord, Tenant shall be entitled to a credit in the net amount of rent and other charges received by Landlord in reletting, after deduction
of all reasonable expenses incurred in reletting the Premises (including, without limitation, remodeling costs, brokerage fees and the like), and in collecting the rent in connection therewith, in the following manner: 

  
 23 

 Amounts received by Landlord after reletting shall first be applied against such
Landlord’s expenses, until the same are recovered, and until such recovery, Tenant shall pay, as of each day when a payment would fall due under this Lease, the amount which Tenant is obligated to pay under the terms of this Lease
(Tenant’s liability prior to any such reletting and such recovery not in any way to be diminished as a result of the fact that such reletting might be for a rent higher than the rent provided for in this Lease); when and if such expenses have
been completely recovered, the amounts received from reletting by Landlord as have not previously been applied shall be credited against Tenant’s obligations as of each day when a payment would fall due under this Lease, and only the net amount
thereof shall be payable by Tenant. Further, Tenant shall not be entitled to any credit of any kind for any period after the date when the term of this Lease is scheduled to expire according to its terms. 

Landlord agrees to use reasonable efforts to relet the Premises after Tenant vacates the same in the event this Lease is terminated based upon
an Event of Default by Tenant hereunder. The marketing of the Premises in a manner similar to the manner in which Landlord markets other premises within Landlord’s control within the Office Area shall be deemed to have satisfied Landlord’s
obligation to use “reasonable efforts” hereunder in no event shall Landlord be required to (i) solicit or entertain negotiations with any other prospective tenant for the Premises until Landlord obtains full and complete possession of
the Premises (including, without limitation, the final and unappealable legal right to relet the Premises free of any claim of Tenant), (ii) relet the Premises before leasing other vacant space in the Office Area, or (iii) lease the Premises
for a rental less than the current fair market rent then prevailing for similar office space in the Office Area. 
 13.4 Liquidated
Damages 
 Landlord may elect, as an alternative, to have Tenant pay liquidated damages, which Tenant at any time after the termination
of this Lease under Section 13.2, above, and whether or not Landlord shall have collected any damages as hereinbefore provided in this Article XIII, and in lieu of all other such damages beyond the date of such notice. Upon such notice, Tenant
shall promptly pay to Landlord, as liquidated damages, in addition to any damages collected or due from Tenant from any period prior to such notice and all expenses which Landlord may have incurred with respect to the collection of such damages,
such a sum as at the time of such notice represents the amount of the excess, if any, of (a) the discounted present value, at a discount rate of [***], of the Annual Fixed Rent, Additional Rent and other charges which would have been payable by
Tenant under this Lease for the remainder of the Lease Term if the Lease terms had been fully complied with by Tenant, over and above (b) the discounted present value, at a discount rate of [***], of the Annual Fixed Rent, Additional Rent and
other charges that would be received by Landlord if the Premises were released at the time of such notice for the remainder of the Lease Term at the fair market value (including provisions regarding periodic increases in Annual Fixed Rent if such
are applicable) prevailing at the time of such notice as reasonably determined by Landlord. 
 Nothing contained in this Lease shall limit
or prejudice the right of Landlord to prove for and obtain in proceedings for bankruptcy or insolvency by reason of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and
governing the proceeds in which, the damages are to be proved, whether or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above. 

  
 24 

 In lieu of any other damages or indemnity and in lieu of the recovery by Landlord of all
sums payable under all the foregoing provisions of this Section 13.4, Landlord may elect to collect from Tenant, by notice to Tenant, at any time after this Lease is terminated under any of the provisions contained in this Article XIII or
otherwise terminated by breach of any obligation of Tenant and before such full recovery, and Tenant shall thereupon pay, as liquidated damages, an amount equal to the sum of the Annual Fixed Rent and all Additional Rent payable for the six
(6) months ended next prior to the such termination (or such lesser amount if less than six (6) months remains) plus the amount of Annual Fixed Rent and Additional Rent of any kind accrued and unpaid at the time of such election plus any
and all expenses which the Landlord may have incurred for and with respect to the collection of any of such rent. 
 13.5 Waiver of
Redemption 
 Tenant, for itself and any and all persons claiming through or under Tenant, including its creditors, upon the termination
of this Lease and the terms of this Lease in accordance with the terms hereof, or in the event of entry of judgment for the recovery of the possession of the Premises in any action or proceeding, or if Landlord shall enter the Premises by process of
law or otherwise, hereby waives any right of redemption provided or permitted by any statute, law or decision now or hereafter in force, and does hereby waive, surrender and give up all rights or privileges which it or they may or might have under
and by reason of any present or future law or decision, to redeem the Premises or for a continuation of this Lease for the term of this Lease hereby demised after having been dispossessed or ejected therefrom by process of law, or otherwise. 

13.6 Landlord’s Default 

Landlord shall in no event be in default in the performance of any of Landlord’s obligations hereunder unless and until Landlord shall
have failed to perform such obligations within [***], or such additional time as is reasonably required to correct any such default, after notice by Tenant to Landlord properly specifying wherein Landlord has failed to perform any such obligation.
Tenant shall not assert any right to deduct the cost of repairs or any monetary claim against Landlord from rent thereafter due and payable, but shall look solely to Landlord for satisfaction of such claim. 

  
 25 

 ARTICLE XIV. 

MISCELLANEOUS PROVISIONS 
 14.1
Waiver 
 Failure on the part of Landlord or Tenant to complain of any action or non-action
on the part of the other, no matter how long the same may continue, shall never be a waiver by Tenant or Landlord, respectively, of any of its rights hereunder. Further, no waiver at any time of any of the provisions hereof by Landlord or Tenant
shall be construed as a waiver of any of the other provisions hereof, and a waiver at any time of any of the provisions hereof shall not be construed as a waiver at any subsequent time of the same provisions. The consent or approval of Landlord or
Tenant to or of any action by the other requiring such consent or approval shall not be construed to waive or render unnecessary Landlord’s or Tenant’s consent or approval to or of any subsequent similar act by the other. No payment by
Tenant, or acceptance by Landlord, of a lesser amount than shall be due from Tenant to Landlord shall be treated otherwise than as a payment on account. The acceptance by Landlord of a check for a lesser amount with an endorsement or statement
thereon, or upon any letter accompanying such check, that such lesser amount is payment in full, shall be given no effect, and Landlord may accept such check without prejudice to any other rights or remedies which Landlord may have against Tenant.
Further, the acceptance by Landlord of Annual Fixed Rent, Additional Rent or any other charges paid by Tenant under this Lease shall not be or be deemed to be a waiver by Landlord of any default by Tenant, whether or not Landlord knows of such
default, except for such defaults as to which such payment relates. 
 14.2 Cumulative Remedies 

Except as expressly provided in this Lease, the specific remedies to which Landlord and Tenant may resort under the terms of this Lease are
cumulative and are not intended to be exclusive of any other remedies or means of redress which they may be lawfully entitled to seek in case of any breach or threatened breach of any provisions of this Lease. In addition to the other remedies
provided in this Lease, Landlord shall be entitled to the restraint by injunction of the violation or attempted or threatened violation of any of the covenants, conditions or provisions of this Lease or to seek specific performance of any such
covenants, conditions or provisions, provided, however, that the foregoing shall not be construed as a confession of judgement by Tenant. 

14.3 Quiet Enjoyment 

This Lease is subject and subordinate to all matters of record. Landlord agrees that, upon Tenant’s paying the Annual Fixed Rent,
Additional Rent and other charges herein reserved, and performing and observing the covenants, conditions and agreements hereof upon the part of Tenant to be performed and observed, Tenant shall and may peaceably hold and enjoy the Premises during
the term of this Lease (exclusive of any period during which Tenant is holding over after the expiration or termination of this Lease without the consent of Landlord), without interruption or disturbance from Landlord or persons claiming through or
under Landlord, subject, however, to the terms of this Lease. This covenant shall be construed as running with the land to and against subsequent owners and successors in interest, and is not, nor shall it operate or be construed as, a personal
covenant of Landlord, except to the extent of the Landlord’s interest in the Premises, and this covenant and any and all other covenants of Landlord contained in this Lease shall be binding upon Landlord and upon such subsequent owners or
successors in interest of Landlord’s interest under this Lease, including ground or master lessees, to the extent of their respective interests, as and when they shall acquire same and then only for so long as they shall retain such interest.

  
 26 

 14.4 Surrender 

No act or thing done by Landlord during the Lease 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. No employee of Landlord or of Landlord’s agents shall have any power to accept the keys of the Premises as an acceptance of a surrender of the Premises prior to the
termination of this Lease; provided, however, that the foregoing shall not apply to the delivery of keys to Landlord or its agents in its (or their) capacity as managing agent or for purpose of emergency access. In any event, however, the delivery
of keys to any employee of Landlord or of Landlord’s agents shall not operate as a termination of the Lease or a surrender of the Premises. Upon the expiration or earlier termination of the Lease Term, Tenant shall surrender the Premises to
Landlord in the condition as required by Sections 7.1 and 8.4, first removing all goods and effects of Tenant and completing such other removals as may be permitted or required pursuant to Section 8.4. 

14.5 Brokerage 
 Tenant
warrants and represents that Tenants has not dealt with any broker in connection with the consummation of this Lease other than the broker, person or firm designated in Section 1.2 hereof; and in the event any claim is made against the Landlord
relative to dealings with brokers other than the broker designated in Section 1.2 hereof, Tenant shall defend the claim against Landlord with counsel of Landlord’s selection and save harmless and indemnify Landlord on account of loss, cost
or damage which may arise by reason of such claim. Landlord warrants and represents that Landlord has not dealt with any broker in connection with the consummation of this Lease other than the broker, person or firm designated in Section 1.2
hereof; and in the event any claim is made against Tenant relative to dealings with brokers other than the broker designated in Section 1.2 hereof, Landlord shall defend the claim against Tenant with counsel of Tenant’s selection and save
harmless and indemnify Tenant on account of loss, cost or damage which may arise by reason of such claim. Landlord agrees that it shall be solely responsible for the payment of brokerage commissions to the broker, person or firm designated in
Section 1.2 hereof. 
 14.6 Recording; Confidentiality 

Each of Landlord and Tenant agree not to record this Lease. Tenant agrees that this Lease and the terms contained herein will be treated as
strictly confidential and except as required by law (or except with the written consent of Landlord) Tenant shall not disclose the same to any third party except for Tenant’s partners, lenders, accountants and attorneys who have been advised of
the confidentiality provisions contained herein and agree to be bound by the same. In the event Tenant is required by law to provide this Lease or disclose any of its terms, Tenant shall give Landlord prompt notice of such requirement prior to
making disclosure so that Landlord may seek an appropriate protective order. If failing the entry of a protective order Tenant is compelled to make disclosure, Tenant shall only disclose portions of the Lease which Tenant is required to disclose and
will exercise reasonable efforts to obtain assurance that confidential treatment will be accorded to the information so disclosed. 

  
 27 

 14.7 Notices and Time for Action 

Whenever, by the terms of this Lease, notice shall or may be given either to Landlord or to Tenant, such notices shall be in writing and shall
be sent by hand, registered or certified mail, or overnight or other commercial courier, postage or delivery charges, as the case may be, prepaid as follows: 

If intended for Landlord, addressed to Landlord at the address set forth on the first page of this lease to the attention of General Counsel,
and copies in like fashion to: 
 [***] 

If intended for Tenant, addressed to Tenant at the address set forth in Article I of this Lease except that from and after the Commencement
Date the address of Tenant shall be the Premises (or to such other address or addresses may from time to time hereafter be designated by Tenant by like notice). 

Except as otherwise provided herein, all such notices shall be effective when received; provided, that (i) if receipt is refused receipt
is refused, notice shall be effective upon the first occasion that such receipt is refused, (ii) if the notice is unable to be delivered due to a change of address of which no notice was given, notice shall be effective upon the date such
delivery was attempted (iii) if notice address is a post office box number, notice shall be effective the day after such notice is sent as provided hereinabove or (iv) if the notice is to a foreign address, notice shall be effective [***]
after such notice is sent as provided hereinabove. Any notice given by an attorney on behalf of Landlord or by Landlord’s managing agent shall be considered as given by Landlord and shall be fully effective. Time is of the essence with respect
to any and all notices and periods for giving of notice or taking any action thereto under this Lease. 
 14.8 Subordination 

This Lease is and shall be subject and subordinate to all ground and underlying leases and to the liens of all mortgages or deeds of trust
which may now or hereafter affect or encumber the Building or the Property and to all renewals, modifications, consolidation, replacements or extensions thereof. This paragraph shall be self operative and no further instrument of subordination shall
be required. In confirmation of any such subordination, Tenant shall at Landlord’s request execute within [***] after receipt, any appropriate certificate or other document that Landlord may reasonably request. Tenant hereby constitutes and
appoints Landlord as Tenant’s attorney in fact to execute any such certificate or other document for or on behalf of Tenant if Tenant does not execute said certificate or document within [***] from receipt thereof. Notwithstanding the foregoing
to the contrary, any ground lessor, mortgage holder or beneficiary of a deed of trust may, at its option, subordinate the lien of its respective ground lease, mortgage or deed of trust to this Lease by giving Tenant [***] prior written notice of
such election, whereupon this Lease shall, irrespective of dates of execution, delivery and recording, be superior to such ground lease, mortgage or deed of trust and no other documentation shall be necessary to effect such change. 

  
 28 

 Tenant agrees that in the event that any proceedings are brought for the foreclosure of any
mortgage, Tenant shall attorn to the purchaser at such foreclosure sale, if requested to do so by such purchaser. Upon such attornment, this Lease shall continue in full force and effect as a direct lease between such purchaser and Tenant upon all
of the terms, conditions and covenants as are set forth in this Lease, except that such purchaser shall not be liable in any way to Tenant for any act or omission, neglect or default on Landlord’s part under this Lease or be responsible for any
monies owing by or on deposit with Landlord to Tenant’s credit or be subject to any rental credit, offset or abatement theretofore accruing to Tenant. Tenant agrees at any time and from time to time to execute a suitable instrument in
confirmation of Tenant’s agreement to attorn, as aforesaid. Tenant waives the provisions of any statute or rule of law now or hereafter in effect which may give or purport to give Tenant any right to terminate or otherwise adversely affect this
Lease and the obligations of Tenant hereunder in the event that any such foreclosure proceeding is prosecuted or completed. 

Notwithstanding the foregoing, Landlord will use reasonable efforts to obtain a so-called
subordination, non-disturbance attornment agreement from the existing and any future mortgage holder of the Project, which agreement shall be on such mortgage holder’s standard form of agreement;
provided, however, that if, despite such reasonable efforts, Landlord is unable to obtain such agreement such failure shall not constitute a default by Landlord under this Lease. 

14.9 Notice to Mortgagee and Ground Lessor 

After receiving notice from any person, firm or other entity that it holds a mortgage which includes the Premises as part of the mortgaged
premises, or that it is the ground lessor under a lease with Landlord as ground lessee, which includes the Premises as a part of the leased premises, no notice from Tenant to Landlord shall be effective unless and until a copy of the same is given
to such holder or ground lessor at the address as specified in said notice (as it may from time to time be changed), and the curing of any of Landlord’s defaults by such holder or ground lessor within a reasonable time after such notice
(including a reasonable time to obtain possession of the premises if the mortgagee or ground lessor elects to do so) shall be treated as performance by Landlord. For the purposes of this Section 14.9, the term “mortgage”
includes a mortgage on a leasehold interest of Landlord (but not one on Tenant’s leasehold interest). 
 14.10 Status Report

 Recognizing that Landlord may find it necessary to establish to third parties, such as accountants, banks, potential or existing
mortgagees, potential purchasers or the like, the then current status of performance hereunder, Tenant, within [***] after the request of Landlord made from time to time, will furnish to Landlord, or any existing or potential holder of any mortgage
encumbering the Premises, the Office Area or the Project, or any potential purchaser of the Premises, the Office Area, or the Project (each an “Interested Party”) a statement of the status of any matter pertaining to this Lease,
including, without limitation, acknowledgments that (or the extent to which) each party is in compliance with its obligations under the terms of this Lease. 

  
 29 

 14.11 Self-Help 

If Tenant shall at any time fail to make any payment or perform any act which Tenant is obligated to make or perform under this Lease and (except in the case
of emergency) if the same continues unpaid or unperformed beyond applicable grace periods, then Landlord may, but shall not be obligated so to do, after [***] written notice to and demand upon Tenant, or without notice to or demand upon Tenant in
the case of any emergency, and without waiving, or releasing Tenant from, any obligations of Tenant in this Lease contained, make such payment or perform such act which Tenant is obligated to perform under this Lease in such manner and to such
extent as may be reasonably necessary, and, in exercising any such rights, pay any costs and expenses, employ counsel and incur and pay reasonable attorneys’ fees. All sums so paid by Landlord and all reasonable and necessary costs and expenses
of Landlord incidental thereto, together with interest thereon at the annual rate equal to the sum of (a) the Base Rate from time to time announced by Bank of America, N.A, or its successor as its Base Rate and (b) [***] (but in no event
greater than the maximum rate permitted by applicable law), from the date of the making of such expenditures by Landlord, shall be deemed to the Additional Rent and, except as otherwise in this Lease expressly provide, shall be payable to the
Landlord on demand, and if not promptly paid shall be added to any rent then due or thereafter becoming due under this Lease, and Tenant covenants to pay any such sum or sums with interest as aforesaid, and Landlord shall have (in addition to any
other right or remedy of Landlord) the same rights and remedies in the event of the non-payment thereof by Tenant as in the case of default by Tenant in the payment of Annual Fixed Rent. 

14.12 Holding Over 
 Any
holding over by Tenant after the expiration of the term of this Lease shall be treated as a tenancy at sufferance and shall be on the terms and conditions as set forth in this Lease, as far as applicable except that Tenant snail pay as a use and
occupancy charge an amount equal to [***] of the Annual Fixed Rent and Additional Rent calculated (on a daily basis) at the highest rate payable under the terms of this Lease for the period measured from the day on which Tenant’s hold-over
commences and terminating on the day on which Tenant vacates the Premises. In addition, Tenant shall save Landlord, its agents and employees harmless and will exonerate, defend and indemnify Landlord, its agents and employees from and against any
and all damages which Landlord may suffer on account of Tenant’s hold-over in the Premises after the expiration or prior termination of the term of this Lease. Nothing in the foregoing nor any other term or provision of this Lease shall be
deemed to permit Tenant to retain possession of the Premises or hold over in the Premises after the expiration or earlier termination of the Lease Term. All property which remains in the Office Area or the Premises after the expiration or
termination of this Lease shall be conclusively deemed to be 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 part thereof shall be sold, then Landlord
may receive the proceeds of such sale and apply the same, at its option against the expenses of the sale, the cost of moving and storage, any arrears of rent or other charges payable hereunder by Tenant to Landlord and any damages to which Landlord
may be entitled under this Lease and at law and in equity. 

  
 30 

 14.13 Entry by Landlord 

Landlord, and its duly authorized representatives, shall, upon reasonable prior notice (except in the case of emergency), have the right to
enter the Premises at all reasonable times (except at any time in the case of emergency) for the purposes of inspecting the condition of same and making such repairs, alterations, additions or improvements thereto as may be necessary if Tenant fails
to do so as required hereunder (but the Landlord shall have no duty whatsoever to make any such inspections, repairs, alterations, additions or improvements except as otherwise provided in Article IV and Section 6.1), and to show the Premises
to prospective tenants during the twelve (12) months preceding expiration of the term of this Lease as it may have been extended and at any reasonable time during the Lease Term to show the Premises to prospective purchasers and mortgagees.
Landlord shall use reasonable efforts to minimize any interference with Tenant’s operation of its business in the Premises, and any appurtenant rights herein granted (including, without limitation, Tenant’s access to and from the Premises)
arising from any entry into the Premises by Landlord. 
 14.14 Tenant’s Payments 

Each and every payment and expenditure, other than Annual Fixed rent, shall be deemed to be Additional Rent hereunder, whether or not the
provisions requiring payment of such amounts specifically so state, and shall be payable, unless otherwise provided in this Lease, within [***] after we after written demand by Landlord, and in the case of the
non-payment of any such amount, Landlord shall have, in addition to all of its other rights and remedies available to Landlord hereunder or by law in the case of
non-payment of Annual Fixed Rent. Unless expressly otherwise provided in this Lease, the performance and observance by Tenant of all the terms, covenants and conditions of this Lease to be performed and
observed by Tenant shall be at Tenant’s sole cost and expense. If Tenant has not objected to any statement of Additional Rent which is rendered by Landlord to Tenant within [***] after Landlord has rendered the same to Tenant, then the same
shall be deemed to be a final account between Landlord and Tenant not subject to any further dispute. In the event that Tenant shall seek Landlord’s consent or approval under this Lease, then Tenant shall reimburse Landlord, upon demand, as
Additional Rent, for all reasonable costs and expenses, including legal and architectural costs and expenses, incurred by Landlord in processing such request, whether or not such consent or approval shall be given. 

14.15 Late Payment 
 If Landlord shall
not have received any payment or installment of Annual Fixed Rent or Additional Rent (the “Outstanding Amount”) on or before the date on which the same first becomes payable under this Lease (the “Due Date”), the
amount of such payment or installment shall incur a late charge equal to the sum of: (a) [***] of the Outstanding Amount for administration and bookkeeping costs associated with the late payment and (b) interest on the Outstanding Amount from
the Due Date through and including the date such payment or installment is received by Landlord, at a rate equal to the lesser of (i) the rate announced by Bank of America, N.A. (or its successor) from time to time as its prime or base rate (or
if such rate is no longer available, a comparable rate reasonably selected by Landlord), plus [***], or (ii) the maximum applicable legal rate, if any. Such interest shall be deemed Additional Rent and shall be paid by Tenant to Landlord upon
demand. Notwithstanding the foregoing, Tenant shall be entitled to a grace period of [***] after written notice from Landlord with respect to the first two late payments in any twelve (12) month period before any such late charge or interest
shall be payable. 

  
 31 

 14.16 Landlord Liability 

Tenant shall neither assert nor seek to enforce any claim for breach of this Lease against any of Landlord’s assets other than
Landlord’s interest in the Project, and Tenant agrees to look solely to such interest for the satisfaction of any liability of Landlord under this Lease, it being specifically agreed that neither Landlord, nor any successor holder of
Landlord’s interest hereunder, nor any beneficiary of any Trust of which any person from time to time holding Landlord’s interest is Trustee, nor any such Trustee, nor any member, manager, partner, director or stockholder nor
Landlord’s managing agent shall ever be personally liable for any such liability. This paragraph shall not limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord or Landlord’s successors-in-interest, or to take any other action which shall not involve the personal liability of Landlord, or of any successor holder of Landlord’s interest
hereunder, or of any beneficiary of any trust of which any person from time to time holding Landlord’s interest is Trustee, or of any such Trustee, or of any manager, member, partner, director or stockholder of Landlord or of Landlord’s
managing agent, to respond in monetary damages from Landlord’s assets other than Landlord’s interest in said Project, as aforesaid, but in no event shall Tenant have the right to terminate or cancel this Lease or to withhold rent or set-off 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 demised premises (constructive or actual) by Landlord continuing after notice to Landlord thereof and a reasonable opportunity for Landlord to cure the same. In no even shall Landlord ever be liable for any indirect or consequential damages
or loss of profits or the like. In the event that Landlord shall be determined to have wrongfully withheld any consent or approval under this Lease, the sole recourse and remedy of the Tenant in respect thereof shall be to specifically enforce
Landlord’s obligation to grant such consent or approval, and in no event shall the Landlord be responsible for any damages of whatever nature in respect of its failure to give such consent or approval nor shall the same otherwise affect the
obligations of the Tenant under this Lease or act as any termination of this Lease. 
 14.17 Miscellaneous 

The relationship of the parties hereto is that of landlord and tenant and no partnership, joint venture or participation is hereby created.
The obligations of this Lease shall run with the land, and except as herein otherwise provided, the terms hereof shall be binding upon and shall inure to the benefit of the successors and assigns, respectively, of Landlord and Tenant and, if Tenant
shall be an individual, upon and to his heirs, executors, administrators, successors and assigns. Each term and each provision of this Lease to be performed by Tenant shall be construed to be both a covenant and a condition. The reference contained
to successors and assigns of Tenant is not intended to constitute a consent to assignment by Tenant, but has reference only to those instances in which Landlord may have later given consent to a particular assignment as required by the provisions of
Article X hereof. This Lease shall be governed exclusively by the provisions hereof and by the law of The Commonwealth of Massachusetts, as the same may from time to time exist. This Lease may be executed in several counterparts, each of which shall
be deemed an original, and such counterparts shall constitute but one and the same instrument. This Lease constitutes the entire agreement between the parties hereto, Landlord’s managing agent and their respective affiliates with respect to the
subject matter hereof and thereof and supersedes all prior dealings between them with respect to such subject matter, and there are no verbal or collateral understandings, agreements, representations or warranties not expressly set forth in this
Lease. No subsequent alteration, amendment, change or addition to this Lease shall be binding upon Landlord or Tenant, unless reduced to writing and signed by the party or parties to be charged therewith. The paragraph headings throughout this
instrument are for convenience and reference only, and the words contained therein shall in no way be held to explain, modify, amplify or aid in the interpretation, construction or meaning of the provisions of this Lease. If any term or provision of
this Lease or the application thereof to any person or circumstance shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term or provision to persons or circumstances other than those as to which
it is held invalid or unenforceable, shall not be affected thereby, and each term and provision of this Lease shall be valid and be enforced to the fullest extent permitted by law. Employees or agents of Landlord have no authority to make or agree
to make a lease or any other agreement or undertaking in connection herewith. The submission-of this document for examination and negotiation does not constitute an offer to lease, or a reservation of, or
option for, the Premises, and this document shall become effective and binding only upon the execution and delivery hereof by both Landlord and Tenant. All negotiations, considerations, representations and understandings between Landlord and Tenants
are incorporated herein and may be modified or altered only by written agreement between Landlord and Tenant, and no act or omission of any employee or agent of Landlord shall alter, change or modify any of the provisions hereof. Landlord and Tenant
hereby represents and warrants to the other that all necessary action has been taken to enter this Lease and that the person signing this Lease on behalf of Landlord and Tenant has been duly authorized to do so. 

  
 32 

 14.18 Waiver of Trial by Jury 

To induce Landlord to enter into this Lease, the Tenant hereby waives any right to trial by jury in any action, proceeding or counterclaim
brought by either Landlord or Tenant on any matters whatsoever arising out of or any way connected with this Lease, the relationship of the Landlord and the Tenant, the Tenant’s use or occupancy of the premises and/or any claim of injury or
damage, including but not limited to, any summary process eviction action. 
 14.19 Landlord’s Future
Redevelopment/Changes 
 Tenant acknowledges that Landlord intends to undertake a redevelopment of the Project that may include, among
other changes, the replacement of the existing garage with a subsurface parking facility and the replacement of some of the existing retail and/or common areas of the Project with new construction (the “Redevelopment”).
Notwithstanding any provision of the Lease to the contrary, Landlord and Tenant agree as follows: 
 A. In connection with the
Redevelopment: 
 (1) Landlord shall provide Tenant with reasonable advance notice prior to the commencement of the Redevelopment work. 

(2) In carrying out any Redevelopment work, Landlord shall use commercially reasonable efforts to minimize any adverse effect upon, or
interference with, the use and enjoyment by Tenant of the Premises. 

  
 33 

 (3) Landlord shall provide Tenant with reasonable advance notice of any work in connection
with the Redevelopment planned in the immediate vicinity of the Premises or that will affect pedestrian access to the Premises or vehicular access to and from the garage. Subject to force majeure events. Landlord will provide elevator access to the
floor on which the Premises are located throughout the Redevelopment. 
 (4) At all times during the Redevelopment, Tenant shall have a
reasonable means of access from a public street to the Premises and between the parking facilities in the Project to the Premises. 
 (5) At
all times during the Redevelopment, Landlord shall provide parking within the Project, or in an offsite facility reasonably proximate to the Project, for not less than Tenant’s parking allocation. 

(6) In connection with any installation, replacement or relocation of Project services, pipes, ducts, conduits, wires and/or appurtenant
fixtures, Landlord shall not unreasonably interfere with Tenant’s use of the Premises, and any such installations, replacements and relocations in or about the Premises shall be located so far as practicable above ceiling surfaces, below floor
surfaces or within perimeter walls of the Premises. 
 (7) Throughout the Redevelopment, Landlord shall make available to Tenant a
construction representative who is available on a 24-7 basis. 
 B. Tenant acknowledges that the
Project, and its mix of uses, may be altered, expanded, with facilities reduced or otherwise changed from time to time, and that Landlord reserves the right to modify the Project, to change the uses thereof, and to designate areas of the Project as
common areas or common facilities, or as areas/facilities for the exclusive use of one or more occupants or one or more uses, all as more particularly set forth below. 

C. Landlord reserves for its benefit all rights of ownership and use in all respects outside the Premises, including without limitation, all
structures and improvements and plazas and common areas and facilities in the Project. Without limitation of the foregoing, it is understood that in its sole discretion Landlord shall have the right to change and rearrange the common areas and
facilities, to add to, change, relocate and eliminate such areas and facilities, to erect new buildings and structures thereon, to permit the use of or lease all or part thereof for exhibitions and displays, to sell, lease or dedicate all or part
thereof to public use, and to configure the public and private roadways in the vicinity of the Project, subject to the issuance of necessary governmental approvals, which reconfigurations shall not be deemed to be eminent domain takings subject to
the provisions of Article XII of the Lease. Tenant’s rights under the Lease to use the common areas and facilities of the Project, and, if applicable, other areas outside the Premises, shall be subject to Landlord’s right to change or
alter the same as set forth herein. 
 D. Landlord reserves the right to add to, change or eliminate any services offered to the occupants
of the Project from time to time; provided, however, that Landlord shall not change or eliminate any such services required to be provided by Landlord to Tenant pursuant to the Lease. 

  
 34 

 E. Landlord shall not be liable to Tenant for any compensation or reduction of rent by
reason of inconvenience or annoyance or for loss of business arising from the exercise of Landlord’s rights hereunder. If Landlord is prevented or delayed from making any repairs, alterations or improvements, or furnishing any services or
performing any other covenant or duty to be performed on Landlord’s part under the Lease, by reason of any cause reasonably beyond Landlord’s control in connection with the exercise of its rights hereunder, Landlord shall not be liable to
Tenant therefor, nor shall Tenant, except as otherwise expressly set forth in the last paragraph of Section 6.3 of this Lease, be entitled to any abatement or reduction of rent by reason thereof. Tenant shall not have the right to
terminate the Lease due to the exercise of Landlord’s rights hereunder, nor shall the same give rise to a claim in Tenant’s favor that such failure constitutes actual or constructive, total or partial, eviction from the Premises. Without
limitation of the foregoing, in no event shall Tenant seek injunctive or any similar relief, to stop, delay or modify the Redevelopment. 

14.20 Rooftop Equitant 
 Tenant shall
have the non-exclusive right to use a portion of the roof of the Office Area, which portion shall be designated by Landlord, for the installation of a satellite dish (the “Rooftop Equipment”)
for use in connection with Tenant’s business in the Premises, provided that (i) the Rooftop Equipment is permitted under the applicable laws, rules and regulations of the Federal Communications Commission, the Federal Aviation
Administration, the Commonwealth of Massachusetts and any other governmental and quasi-governmental authorities having jurisdiction over the Project or Landlord, (ii) the Rooftop Equipment conforms to all such applicable laws, rules and
regulations, (iii) Tenant has obtained all permits, licenses, variances, authorizations and approvals that may be required in order to install such Rooftop Equipment and any insurance required by Landlord, (iv) the satellite dish is not
more than thirty- six inches (36”) in diameter, (v) the Rooftop Equipment is not more than the weight that Landlord shall reasonably determine is appropriate for the roof (which Landlord shall specify to Tenant upon Tenant’s written
request), (vi) Tenant installs any screen or other covering for the Rooftop Equipment that Landlord in its reasonable discretion may require (the size, type and style of which shall be subject to Landlord’s prior written approval) in order to
camouflage or conceal the Rooftop Equipment, (vii) Tenant shall pay Landlord (within [***] after receipt of an invoice therefor) an amount equal to all reasonable cost incurred by Landlord to have an engineer review the plans and specifications
for the Rooftop Equipment, the location specifications for the Rooftop Equipment and the plans, specifications and method for attaching the Rooftop Equipment to the Office Area, and (viii) the Rooftop Equipment do not adversely affect any
antenna or other equipment that is on the roof of the Office Area. In addition, the style, color, materials, exact location and method of installation of the Rooftop Equipment must be approved by Landlord (in its sole, but good faith, discretion).
Tenant shall maintain the Rooftop Equipment in good condition and repair and in compliance with all applicable laws, rules, regulations and requirements. 

  
 35 

 Prior to or contemporaneously with requesting Landlord’s approval of the installation
of the Rooftop Equipment, Tenant shall provide to Landlord: (i) plans and specifications for the Rooftop Equipment (including size, location, height, weight and color) and plans and specifications for the installation thereof (the
“Rooftop Equipment Plans”); (ii) copies of all required governmental and quasi-governmental permits, licenses, special zoning variances, and authorizations, all of which Tenant shall obtain at its own cost and expense; and
(iii) a policy or certificate of insurance evidencing such insurance coverage as may reasonably be required by Landlord for the installation, operation and maintenance of the Rooftop Equipment and sufficient to cover, among other things, the
indemnities from Tenant to Landlord provided in the Lease. Landlord may withhold its approval of the installation of the Rooftop Equipment if the installation, operation or removal of the Rooftop Equipment may (1) damage the structural
integrity of the Project or void any warranty or guaranty applicable to the roof or any portion of the Project, (2) materially interfere with any service provided by Landlord to the Project or any tenant or occupant thereof, (3) materially
interfere with the use of any part of the Project by any tenant or occupant in the Project, or (4) cause the violation of any zoning ordinance or governmental or quasi-governmental law rule or regulation applicable to the Project. Tenant shall
not be entitled to rely on any such approval as being a representation by Landlord that such installation and operation is permitted by or in accordance with any zoning ordinance or other quasi-governmental law, rule or regulation applicable to the
Project. Landlord at its sole option and discretion, may require Tenant, at any time prior to the expiration of this Lease, to terminate the operation of the Rooftop Equipment if it is causing physical damage to the structural integrity of the
Project or voids any warranty or guaranty applicable to the roof or the Project, material interferes with any other service provided by the Project, materially interferes with any other tenant’s business, or causes the violation of any
condition or provision of this Lease or any governmental or quasi-governmental law, rule or regulation applicable to the Project (now or hereafter in effect). If, however, Tenant can correct the damage or prevent said interference caused by the
Rooftop Equipment to Landlord’s satisfaction within [***], Tenant may restore its operation so long as Tenant promptly commences to cure such damage and diligently pursues such cure to completion. If the Rooftop Equipment is not completely
corrected and restored to operation within [***], Landlord, at its sole option, may require that the Rooftop Equipment be removed at Tenant’s expense. If Landlord or any other tenant in the Project shall require that the Rooftop Equipment be
moved to another location on the roof, either to accommodate Landlord or to provide other tenants or occupants in the Project with access to the roof for placement of other antennas, other electrical equipment or other reasonably Landlord-approved
uses or installations or to avoid interference with future business or uses of any space in the Project, Landlord shall have the right, at its sole expense, to relocate the Rooftop Equipment to another place on the roof, provided that such new
location does not materially adversely affect the operation of such Rooftop Equipment. At the expiration or earlier termination of the Term or upon termination of the operation of the Rooftop Equipment, at Tenant’s sole cost, the Rooftop
Equipment and all cabling and other equipment relating thereto shall be removed from the Project and the area where the Rooftop Equipment was located shall be restored to its condition existing prior to such installation, in a manner and with
materials 
 determined by Landlord. Tenant hereby authorizes Landlord to remove and dispose of the Rooftop Equipment and charge Tenant for all costs and
expenses incurred by Landlord in connection therewith if Tenant has not done so on or before the expiration or earlier termination of the Term of this Lease. Tenant agrees that Landlord shall not be liable for any property disposed of or removed by
Landlord. Tenant’s obligation to perform and observe this covenant shall survive the expiration or earlier termination of the term of this Lease. 

  
 36 

 Tenant covenants and agrees that the installation, operation and removal of the Rooftop
Equipment will be at its sole risk. Tenant covenants and agrees absolutely and unconditionally to indemnify, defend and hold Landlord harmless from and against all claims, actions, damages, liability judgments, settlements, costs and expenses
(including attorney’s fees and expenses) in connection with the loss of life, personal or bodily injury, damage to property or business or any other loss or injury to the extent arising out of the installation, operation, maintenance or removal
of the Rooftop Equipment, including without limitation, any loss or injury resulting from transmissions from the Rooftop Equipment. The provisions of this Section 14.21 are personal to the tenant named herein and cannot be exercised by any
assignee (other than pursuant to a Permitted Transfer) or subtenant or any other person or entity.

FIRST AMENDMENT TO LEASE 

This FIRST AMENDMENT TO LEASE (“Amendment”), is made as of the
17th day of September, 2016 (“Effective Date”) by and between LANDMARK CENTER PARK DRIVE LLC, a Delaware limited liability company (“Landlord”) and
TOAST, INC., a Delaware corporation (“Tenant”). 
 WITNESSETH: 

Reference is hereby made to the following facts: 

A. Landlord and Tenant are parties to that certain Lease dated June 12, 2015 (the “Existing Lease”) for 37,500 square
feet (the “Existing Premises”) on the eighth (8th) floor of that certain building known as The Landmark Center (as more particularly described in the Existing Lease, the
“Building”). All capitalized words and phrases not otherwise defined herein shall have the meanings ascribed to them in the Existing Lease. The Existing Lease, as modified and amended by this Amendment, is referred to herein as the

Term of the Lease through December 31, 2017; and 
 C. Tenant desires to lease additional premises from Landlord, consisting of 6,033
square feet (“First Amendment Praises”), as shown on Exhibit A, attached hereto. 
 WHEREAS, Landlord is willing to:
(i) extend the Term of the Lease for an additional period; and (ii) lease the First Amendment Premises to Tenant upon the terms and conditions hereinafter set forth; 

NOW THEREFORE, in consideration of Ten Dollars ($10.00) and other good and valuable consideration, the receipt, sufficiency and delivery of
which are hereby acknowledged, the parties agree that the Lease is hereby amended as follows: 
  

	1.	 Extension of Term of the Lease. The Term of the Lease is hereby extended to expire on
December 31, 2017 (“Extended Termination Date”), unless sooner terminated, in accordance with, and subject to the terms and conditions set forth in the Lease. The period of time commencing on July 1, 2017 (“First
Extension Term Commencement Date”), and continuing through the Extended Termination Date, is referred to in this Amendment as the “First Extension Term.” Without limitation, all references in the Lease to the
“Term” shall be deemed to include the First Extension Term in all respects. From and after the First Amendment Premises Commencement Date, the term “Premises” in the Lease shall be deemed to mean the Existing Premises and
the First Amendment Premises. 

  
 1

	5.	 Condition of First Amendment Premises. Tenant shall take the First Amendment Premises
“as-is”, in the condition in which the First Amendment Premises are in as of the First Amendment Premises Commencement Date, without any obligation on the part of Landlord to prepare or construct the First Amendment Premises for
Tenant’s occupancy and without any warranty or representation by Landlord as to the condition of the First Amendment Premises, except that Landlord shall, on or before the First Amendment Premises Commencement Date, remove the wall that
separates the Existing Premises from the First Amendment Premises (“Landlord’s Expansion Work”). Whereas Landlord’s Expansion Work shall be performed while Tenant is in occupancy of the Existing Premises, Landlord shall

or property in connection therewith. Prior to such entry, Tenant shall obtain and submit to Landlord all insurance coverages required pursuant to the Lease. Upon such entry, Tenant shall be bound by and shall comply with all provisions of the Lease,
including, without limitation, the provisions of the Lease regarding the performance of alterations, improvements and installations in the First Amendment Premises, notwithstanding that the First Amendment Premises Commencement Date shall be
coordinated with any work being performed by Landlord so as not to delay the completion of Landlord occurred. Without limitation, all of such work performed by Tenant in First Amendment Premises prior to the First Amendment Commencement Date shall
be coordinated with any work being performed by Landlord so as not to delay the completion of Landlord’s Expansion Work. Landlord shall use reasonable good faith efforts to reasonably integrate the work to be completed by Tenant’s vendors
(e.g., wiring and cabling) into Landlord’s Expansion Work schedule such that the Landlord’s Expansion Work and the work to be completed by Tenant’s vendors will be completed in an efficient manner. 

 

	6.	 Electricity and HVAC Charges With Respect to First Amendment Premises. In addition to
Tenant’s obligation to pay for electricity and HVAC charges with respect to the Existing Premises in accordance with Section 5.2 of the Lease, Tenant agrees to pay to Landlord, as Additional Rent, HVAC charges as set forth in

written notice to Tenant at any time) that an Event of Default (as defined in Section 13.1 of the Lease) has not occurred, and that Toast, Inc., itself, and Shoobx, Inc. (with respect to the portion of the Premises that Shoobx, Inc. occupies as

portion (“Expansion Premises”) of the eighth (8th) floor of the Building. The Expansion Premises contains approximately 4,044 square feet, and is substantially as shown on Exhibit B, attached hereto.

  

	 	A.	 Exercise of Rights to Expansion Premises. Tenant may exercise its option to lease the Expansion
Premises by giving written notice (“Exercise Notice”) to Landlord during the Notice Period, as defined in Subparagraph B of this Section 7, in respect of the Expansion Premises. If Tenant fails timely to give the Exercise
Notice, Tenant shall have no further right to lease the Expansion Premises, time being of the essence of this Section 7. Upon the timely giving of the Exercise Notice, Landlord shall lease and demise to Tenant, and Tenant shall hire and take
from Landlord, the Expansion Praises, without the need for further act or deed by either party, for the term and upon all of the same terms and conditions of the Lease, except as hereinafter set forth. 

 

	 	B.	 Notice Period. The Notice Period, in respect of the Expansion Premises shall be defined as any
time between January 1, 2017 March 1, 2017. 

  

	 	C.	 Lease Provisions Applying to Expansion Premises. The leasing to Tenant of the Expansion Premises
shall be upon all the same terms and conditions of the Lease except as follows: 

  

	 	(i)	 The “Expansion Premises Commencement Date” shall be the date that Landlord delivers the
Expansion Premises to Tenant. 

  

	 	(ii)	 The Annual Fixed Rent payable in respect of the Expansion Premises shall be [***] of the Expansion Premises.

  

	 	(iii)	 The Expansion Premises shall be delivered by Landlord and accepted by Tenant “as-is”, in its then
(i.e. as of the Expansion Premises Commencement Date), state of construction, finish and decoration, without any obligation on the part of Landlord to prepare or construct the Expansion Premises for Tenant’s occupancy. In implementation of the
foregoing, Landlord shall have no obligation under Article IV of the Lease in respect of the Expansion Premises. 

  

	 	(iv)	 Notwithstanding the fact that Tenant’s exercise of the above-described expansion option shall be
self-executing, as aforesaid, the parties hereby agree promptly to execute a lease amendment reflecting the addition of the Expansion Premises. The execution of such lease amendment shall not be deemed to waive any of the conditions to Tenant’s
exercise of the herein expansion options, unless otherwise specifically provided in such lease amendment.

	8.	 Brokerage. Tenant warrants and represents that Tenant has not dealt with any broker in connection
with the consummation of this Amendment, and in the event any claim is made against the Landlord relative to dealings with brokers, Tenant shall defend the claim against Landlord with counsel of Landlord’s selection and save harmless and
indemnify Landlord on account of loss, cost or damage which may arise by reason of such claim. Landlord warrants and represents that Landlord has not dealt with any broker in connection with the consummation of this Amendment, and in the event any
claim is made against Tenant relative to dealings with brokers, Landlord shall defend the claim against Tenant with counsel of Tenant’s selection and save harmless and indemnify Tenant on account of loss, cost or damage which may arise by
reason of such claim. 

  

	9.	 Miscellaneous. Tenant hereby represents and warrants to Landlord as follows: (i) the
execution and delivery of this Amendment by Tenant has been duly authorized by all requisite corporate action, (ii) neither the Lease nor the interest of Tenant therein has been assigned, sublet, encumbered or otherwise transferred;
(iii) there are no defenses or counterclaims to the enforcement of the Lease or the liabilities and obligations of Tenant thereunder; (iv) Tenant is not entitled to any offset, abatement or reduction of rent under the Lease; and

this Amendment to Tenant. Except as expressly and specifically set forth in this Amendment, the Existing Lease is hereby ratified and confirmed, and all of the terms, covenants, agreements and provisions of the Existing Lease shall remain unaltered
and unmodified and in full force and effect throughout the balance of the Term of the Lease, as extended hereby. Except as expressly set forth herein, all of the covenants, representations and warranties made by Tenant contained in the Existing
Lease are hereby remade, reaffirmed and ratified as of the date hereof.

(iv) a certification by an appropriate officer of Tenant or by Unispace, pursuant to a mutually agreed upon written contract and, in the event that no contract is entered into with Unispace, then any other architect or contractor

or material supplier’s liens (in a form Landlord shall reasonably require) waiving, releasing and relinquishing all liens, claims and rights to lien under applicable laws on account of any labor, materials and/or equipment furnished by any

 (3) Landlord shall have no obligation to pay Landlord’s Contribution in
respect of any Requisition submitted prior to the Execution Date of this Third Amendment or after January 1, 2019. 

(4) If the cost of the Third Amendment Premises Work exceeds the Allowance, Tenant shall be entitled to Landlord’s
Contribution in accordance with the terms hereof, but each individual disbursement of Landlord’s Contribution shall be disbursed in the proportion that the Allowance bears to the total cost for the Third Amendment Premises Work. 

V. Additional Improvement Allowance—Third Amendment Premises. Tenant shall have the right to borrow up to [***] of the Existing Premises
and the Third Amendment Premises) (the “Additional Allowance”) from Landlord in order to finance the costs of performing the Third Amendment Premises Work in one (1), two (2) or three (3) Requisitions, at Tenant’s
option. The Additional Allowance may only be used for Costs (as defined above) related to the Third Amendment Premises Work. The Additional Allowance shall be paid to Tenant or, at Tenant’s option, through issuance of joint checks payable to
the order of both Tenant and the general contractor that performed the Third Amendment Premises Work or vendor that supplied materials for the Third Amendment Premises Work, as the case may be, within [***] following receipt by Landlord of a
Requisition for the Third Amendment Premises Work pursuant to Section IV.B. above. The Additional Allowance shall be disbursed in the amount reflected on the receipted bills meeting the requirements above. Notwithstanding anything herein to the
contrary, Landlord shall not be obligated to disburse any portion of the Additional Allowance during the continuance of an uncured default under the Lease, and Landlord’s obligation to disburse shall only resume when and if such default is
timely cured. Any Additional Allowance borrowed by Tenant hereunder shall be repaid to Landlord as Additional Rent in twelve (12) equal monthly installments beginning on first day of the twelfth month of the Second Extension Term Commencement
Date, until the Additional Allowance has been repaid in full (with the final payment being adjusted, if necessary, to reflect the remaining balance of the Additional Allowance). In the event that Tenant is in default under this Lease after the
expiration of applicable cure periods, the entire unpaid balance of the Additional Allowance borrowed by Tenant shall become immediately due and payable. 

VI. Landlord’s Termination Right. Notwithstanding anything to the contrary herein or in the Lease contained, Landlord shall have the right,
at any time after July 1, 2018, upon [***] prior written notice to Tenant (delivered no sooner than July 1, 2018), to terminate the Term of the Lease only with respect to that portion of the Premises located on the eighth (8th) floor of the Building containing 2,591 rentable square feet of space and shown on Exhibit D (the “Recapture Space”), attached hereto and incorporated herein, and the
Coop Space, as hereinafter defined, in both instances, which termination shall be effective as of the date (the “Effective Termination Date”) that is the later to occur of (i) the date specified in such notice or (ii) the
date that is [***] from the date that Tenant receives such notice. Upon the timely giving of such notice, the Term of the Lease with respect to the Recapture Space and/or the Coop Space, as applicable, shall terminate as of said Effective
Termination Date, and, with respect to the Recapture Space, Annual Fixed Rent, Additional Rent, and other charges due under the Lease shall be apportioned as of said Effective Termination Date, and thereafter, (x) Tenant shall have no further
rights or obligations with respect to the Recapture Space or Coop Space, as applicable, (except those that by their terms survive the expiration or earlier termination of the Lease) and (y) with respect to the Recapture Space, Tenant’s
Annual Fixed Rent, Additional Rent, and other monthly charges will be proportionally reduced. For the avoidance of doubt, the earliest date on which the Effective Termination Date for the Recapture Space and the Coop Space could occur is

 VII. Parking. 

A. Parking Privileges. Landlord shall cause its affiliate, Landmark Leaseco LLC (“Garage Tenant”), to provide to Tenant
monthly parking privileges in the structured parking facilities serving the Project (the “Garage”) for up to two hundred (200) passenger automobiles on an unreserved basis in the Garage by Tenant’s employees commencing on
January 1, 2018 and continuing through the Second Extended Termination Date. In the event that the Rentable Floor Area of the Premises decreases at any time during the Lease Term, the number of parking privileges provided to Tenant shall be
reduced proportionately. 
 B. Parking Charges. As of January 1, 2018, Tenant shall be entitled to one hundred (100)
parking privileges. Thereafter, Tenant may increase its parking privileges from time to time (up to a maximum of 200) upon [***] prior written notice to Landlord. Tenant shall pay Garage Tenant or, if Garage Tenant so directs, the operator of such
garage (the “Garage Operator”) for such parking privileges at a rate of [***]. Tenant acknowledges that said monthly charges to be paid under this Section are for the use by the Tenant of the parking privileges referred to herein,
and not for any other service. Tenant’s failure to make payment when due to the Garage Tenant or Garage Operator, as the case may be, shall be considered to be a failure in the payment of rent hereunder for which Landlord shall have all its
rights and remedies under this Lease and at law and in equity. 
 C. Garage Operation. Unless otherwise determined by Garage Tenant
or the Garage Operator, the Garage is to be operated on a self-parking basis, and Tenant shall be obligated to park and remove its own automobiles, and Tenant’s parking shall be on an unreserved basis, Tenant having the right to park in any
available stalls. Tenant’s access and use privileges with respect to the Garage shall be in accordance with regulations of uniform applicability to the users of the Garage from time to time established by the Garage Tenant or the Garage
Operator. Tenant shall receive one (1) identification sticker or pass and one (1) magnetic card so-called, or other suitable device providing access to the Garage, for each parking privilege paid for by Tenant. Tenant shall supply Garage
Tenant or the Garage Operator with an identification roster listing, for each identification sticker or pass, the name of the employee and the make, color and registration number of the vehicle to which it has been assigned, and shall provide a
revised roster to Garage Tenant or Garage Operator monthly indicating changes thereto. Any automobile found parked in the Garage during normal business hours without appropriate identification will be subject to being towed at said automobile
owner’s expense. The parking privileges granted herein are non-transferable (other than to a permitted assignee or subtenant pursuant to the applicable provisions of the Lease), provided that for the avoidance of doubt, if an employee of Tenant
ceases using its parking privilege, Tenant shall be entitled to assign such parking privilege to another employee of Tenant. Garage Tenant or the Garage Operator may institute a so-called valet parking program for the Garage, and in such event
Tenant shall cooperate in all respects with such program. Garage Tenant or Garage Operator shall have the right to alter the Garage as it sees fit and in such case to change the Garage including the reduction in area of the same, Tenant
acknowledging that in connection with the potential expansion, reduction and/or change of buildings in the Project or the addition or elimination of other buildings thereto, it may be necessary to make significant changes to the Garage which may
result in the reduction of the amount of parking available in the Garage and the change of location of such parking or may change the access to or egress from the Garage, all of which Garage Tenant or Garage Operator may perform sole and exclusive
discretion, without limitation to its other rights in respect thereof, provided that the terms of Section 14.19 of the Lease shall apply to any such change, 

  
 8 

 D. Limitations. Tenant agrees that it and all persons claiming by, through and under
it, shall at all times abide by all reasonable rules and regulations promulgated by Garage Tenant or the Garage Operator with respect to the use of the Garage. Except to the extent of its negligence or willful misconduct, neither the Landlord, the
Garage Tenant nor the Garage Operator assumes any responsibility whatsoever for loss or damage due to fire or theft or otherwise to any automobile or to any personal property therein, however caused, and Tenant agrees, upon request from the Landlord
or Garage Tenant, from time to time, to notify its officers, employees and agents then using any of the parking privileges provided for herein, of such limitation of liability. Tenant further acknowledges and agrees that a license only is hereby
granted, and no bailment is intended or shall be created. 
 E. Alternative Facilities. Notwithstanding anything to the contrary set
forth herein or in the Lease, Landlord shall have the right, upon [***] prior written notice (delivered no sooner than January 1, 2018) to Tenant, to relocate no more than [***] of Tenant’s parking to one of the following locations: [***]
in order to facilitate the modification of the Garage in connection with the redevelopment of the Project which Landlord shall perform within a commercially reasonable period of time. For the avoidance of doubt, any such relocation of parking shall
not occur prior to April 1, 2018. Any such relocated parking shall be promptly reinstated to the Garage upon completion of Landlord’s modification of the Garage. Unless waived by Tenant, Landlord shall provide Tenant with [***] prior
written notice before reinstating such parking to the Garage. 
 VIII. Amenities. Landlord shall provide Tenant with the following amenities:

 A. Landlord has constructed a communal space (the “Coop Space”) on the eighth (8th) floor of the Building, as shown on Exhibit A-4. Subject to Force Majeure and closures for repair and maintenance, Tenant shall have the right (i) to use the Coop Space on a
nonexclusive basis in common with other tenants, at no additional charge (other than inclusion in Operating Expenses), and (ii) to reserve the Coop Space for its exclusive use from time to time on a first- come, first-served basis. The size and
configuration of the Coop Space available for use by Tenant and other tenants in the Building shall be determined from time to time by Landlord in its sole discretion; provided, however, that Landlord shall not reduce the rentable square footage of
the Coop Event Area, as shown on Exhibit A-4, by more than [***], or materially impair the ingress to or egress from the Coop Space, without Tenant’s prior written consent, which shall not be unreasonably withheld, conditioned or
delayed. Tenant shall reimburse Landlord upon invoice therefor, for all of Landlord’s reasonable third party out-of-pocket costs and the provision of building personnel (including additional security, janitorial or other services reasonably
needed to facilitate Tenant’s exclusive use of the Coop Space) incurred in connection with any exclusive use of the Coop Space by Tenant. Tenant’s use of the Coop Space shall be subject to availability and such rules and regulations as
Landlord may establish from time to time.

repair and maintenance, Tenant shall have the right, once the Outdoor Space is completed, open and operational as determined by Landlord in its sole discretion, (i) to use the Outdoor Space on a nonexclusive basis in common with other tenants,
at no additional charge (other than inclusion in Operating Expenses) and (ii) to reserve the Outdoor Space for its exclusive use from time to time based on availability on a first-come, first-served basis. The size, location and configuration
of the Outdoor Space available for use by Tenant and other tenants in the Building shall be determined from time to time by Landlord in its sole discretion. Tenant shall reimburse Landlord upon invoice therefor, for all of Landlord’s reasonable
third party out-of-pocket costs and the provision of building personnel (including additional security, janitorial or other services reasonably needed to facilitate Tenant’s exclusive use of the Outdoor Space) incurred in connection with any
exclusive use of the Outdoor Space by Tenant. Tenant’s use of the Outdoor Space shall be subject to availability and such rules and regulations as Landlord may establish from time to time.

A. Inapplicable Lease Provisions. Articles III (Lease Term) and IV (Term; Construction) of the Lease, Section 5 (Landlord’s
Expansion Work) of the First Amendment, and Section I.D (Landlord’s Second Amendment Work) of the Second Amendment shall have no applicability with respect to this Third Amendment. 

B. Amended Lease Provisions. 

(i) Section 8.4 of the Lease (Nature of Alterations) is hereby amended by deleting Subsection (b)(i) thereof. For the
avoidance of doubt, notwithstanding anything to the contrary set forth in said Section 8.4(b) of the Lease, Tenant shall not be obligated to remove any Cable from the Premises at the expiration or earlier termination of the Lease Term. 

  
 10 

 (ii) Article X (Assignment and Subletting) of the Lease is hereby amended by
adding the following provisions: 
 “Notwithstanding anything to the contrary set forth in Article X of the Lease,
Landlord’s consent to a proposed sublease or assignment of the Lease shall not be unreasonably withheld, conditioned, or delayed. In determining whether to consent or withhold consent to a Proposed sublease or assignment of the Lease, Landlord
and Tenant agree that Landlord may withhold its consent to any proposed sublease or assignment (other than a Permitted Transfer), and such withholding of consent by Landlord will not be unreasonable, if: (1) if the proposed assignee or
subtenant is a party who would, or whose use would, detract from the character of the Building, such as, Without limitation, a dental, medical, chiropractic or a governmental office; or (2) if the proposed assignee or subtenant proposes to
engage in a business in the Premises which is not consistent with the standards of the Building or is not permitted by or would contravene the provisions of this Lease; or (3) if the lease to, or use of the Premises or any portion thereof by,
such subtenant or assignee will cause Landlord to be in violation of any restrictive use covenants granted by Landlord to any other tenant in the Project in such tenant’s lease; or (4) if, in the case of a proposed assignment, the proposed
assignee is not of sufficient financial worth to perform its obligations underpins Lease as such obligations become due; or (5) the proposed assignee or subtenant is then a tenant in the Project, unless: (i) such tenant desires to sublease
the Premises for expansion purposes only; and (ii) such assignment or sublease will not, either directly or indirectly, cause a vacancy in the premises which such proposed assignee or subtenant then occupies in the Building; and
(iii) Landlord cannot then (i.e., at the time that Tenant requests Landlord’s consent) satisfy such tenant as to the size of premises and length of term; or (6) the proposed assignee or subtenant is then negotiating with Landlord to
become a tenant in the Project; provided, however, it is understood and agreed that bases set forth above upon which Landlord may reasonably withhold its consent to a proposed sublease or assignment are not intended, and shall not be construed, to
be an exclusive list of reasonable bases upon which Landlord may withhold its consent, and Landlord reserves the right to withhold its consent to any proposed sublease or assignment by virtue of any other reasonable basis. 

If Tenant desires to assign this Lease or sublet all or any portion of the Premises (except with respect to a Permitted
Transfer), then Tenant shall give notice thereof to Landlord, which notice shall be accompanied by (a) with respect to an assignment of this Lease, the date Tenant desires the assignment to be effective and (b) with respect to a sublet of
all or a part of the Premises, (i) the material business terms on which Tenant would sublet such premises, and (ii) a description of the portion of the Premises to be sublet. Such notice shall be deemed an offer from Tenant to Landlord
whereby Landlord (or Landlord’s designee) shall be granted the right, at Landlord’s option, (1) to terminate this Lease with respect to such space as Tenant proposes to sublease (the “Partial Space”), upon the terms
and conditions hereinafter set forth, or (2) if the proposed transaction is an assignment of this Lease or a subletting of 50% or more of the rentable square footage of the Premises, to terminate this Lease with respect to the entire Premises.
Such option may be exercised by notice from Landlord to Tenant within [***] after Landlord’s receipt of Tenant’s notice. If Landlord exercises its option to terminate this Lease, as to the entire Premises or as to a Partial Space, pursuant
to the foregoing provisions, then (A) this Lease shall end and expire with respect to all or a portion of the Premises, as the case may be, on the date that such assignment or sublease was to commence (as if such date were the expiration date
of the term hereof), (B) Fixed Rent shall be apportioned, paid, or refunded as of such date, (C) Tenant, upon Landlord’s request, shall enter into an amendment of this Lease ratifying and confirming such total or partial termination,
and setting forth any appropriate modifications to the terms and provisions hereof, (D) Landlord shall be free to lease the Premises, or the portion thereof as to which such termination shall be effective, or any part thereof, to any person or
persons, including, without limitation, to Tenant’s prospective assignee or subtenant, and (E) if a termination as to a Partial Space, Tenant shall be liable for all costs and expenses of segregating the Partial Space from the remaining
Premises, and for the costs of separately demising the Partial Space from the remaining Premises. 

  
 11 

 In the event of an assignment of this Lease or a sublease of the Premises or
any portion thereof to anyone other than pursuant to a Permitted Transfer, Tenant shall pay to Landlord [***] of any Net Sublease Profits (as defined below), payable in accordance with the following. In the case of an assignment of this Lease,
“Net Sublease Profit”: (1) shall be defined as a lump sum in the amount (if any) by which any consideration paid by the assignee in consideration of or as an inducement to Tenant to make said assignment exceeds the reasonable
attorneys’ fees, construction costs and brokerage fees incurred by Tenant in order to effect such assignment (collectively, “Sublease Expenses”), and (2) shall be payable concurrently with the payment to be made by the
assignee to Tenant. In the case of a sublease, “Net Sublease Profit” shall be defined as a monthly amount equal to the amount by which the sublease rent and other charges payable by the subtenant to Tenant under the sublease exceed
the sum of the rent and other charges payable under this Lease for the Premises or allocable to the sublet portion thereof, plus a monthly amount equal to the Sublease Expenses divided by the number of months in the term of the sublease, and shall
be payable on a monthly basis concurrently with the subtenant’s payment of rent to Tenant under the sublease.” 

(iii) Section 14.12 (Holding Over) of the Lease is hereby deleted in its entirety, and amended and restated as follows:

 “14.12 Holding Over 

Any holding over by Tenant after the expiration of the Term of this Lease shall be treated as a tenancy at sufferance and shall
be on the terms and conditions as set forth in this Lease, as far as applicable except that Tenant shall pay as a use and occupancy charge an amount equal to [***]. In addition, Tenant shall save Landlord, its agents and employees harmless and will
exonerate, defend and indemnify Landlord, its agents and employees from and against any and all damages which Landlord may suffer on account of Tenant’s hold-over in the Premises after the expiration or prior termination of the term of this
Lease. Nothing in the foregoing nor any other term or provision of this Lease shall be deemed to permit Tenant to retain possession of the Premises or hold over in the Premises after the expiration or earlier termination of the Lease Term. All
property which remains in the Premises after the expiration or termination of this Lease shall be conclusively deemed to be 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 part thereof shall be sold, then Landlord may receive the proceeds of such sale and apply the same, at its option against the expenses of the sale, the cost of moving and storage, any arrears of rent or other charges payable
hereunder by Tenant to Landlord and any damages to which Landlord may be entitled under this Lease and at law and in equity.” 

  
 12 

 X. Extension Option. 

A. On the conditions (which conditions Landlord may waive by written notice to Tenant) that both at the time of the issuance of the Notice (as
hereinafter defined) and as of the commencement of the Third Extension Term (as hereinafter defined), (i) there exists no “Event of Default” (defined in Article XIII of the Lease) during the Second Extension Term, (ii) the Lease
is still in full force and effect, and (iii) Tenant has neither assigned this Lease nor sublet more than [***] of the Premises (except for a Permitted Transfer as defined in Article X of the Lease, as amended by this Third Amendment), Tenant

 B. If Tenant desires to extend the Term, then Tenant shall
give notice (“Notice”) to Landlord, not later than [***] prior to October 1, 2018. Not later than [***] after Landlord’s receipt of the Notice, Landlord shall provide Tenant with Landlord’s determination of the
then-prevailing fair market rent, and other monetary and nonmonetary terms and conditions, for the Third Extension Term (“Prevailing Market Terms”). If at the expiration of [***] after the date when Landlord provides such Prevailing
Market Terms to Tenant, Landlord and Tenant, despite their good faith efforts, have not reached agreement on Prevailing Market Terms and executed a written instrument extending the Term of this Lease, and making any other agreed-upon changes to the
terms and conditions of this Lease, pursuant to such agreement, then the provisions of this Article X shall terminate and be of no further force or effect and Tenant shall have no further rights with respect to the extension of the Term of this
Lease. 
 XI. Brokerage. Tenant warrants and represents that Tenant has not dealt with any broker in connection with the consummation of this
Third Amendment, other than CBRE - New England (“Tenant’s Broker”), and in the event any claim is made against the Landlord relative to dealings with brokers, other than by Tenant’s Broker, Tenant shall defend the claim

 Notwithstanding anything to the contrary herein contained, so long as no Material Monetary Event of Default (as hereinafter
defined) occurs during calendar year 2019, Tenant shall only be obligated to pay [***] of the Annual Fixed Rent with respect to the Ground Floor Premises from November 1, 2018 through December 31, 2019. 

8. Operating Expenses. Commencing as of January 1, 2020 and continuing through the Third Extension Term, Tenant shall pay the Operating
Expenses Excess (as hereinafter defined) with respect to all of the Premises demised to Tenant in accordance with the provisions of this Section 8: 

A. Operating Expenses Defined. “Operating Expenses Allocable to the Premises” means the same proportion of the
Operating Expenses for the Office Area (as hereinafter defined) as Rentable Floor Area of the Premises bears to the total Rentable Floor Area of the Office Area plus the Rentable Floor Area of the Ground Floor Premises and, if applicable, the
Rentable Floor Area of the BSC RFO Premises. “Base Operating Expenses” means Operating Expenses for the Office Area for calendar year 2019 (that is the period beginning January 1, 2019 and ending December 31, 2019). Base
Operating Expenses shall not include material market-wide cost increases due to extraordinary circumstances beyond the reasonable control of Landlord particular to and only occurring during the Base Year and generally affecting comparable commercial
buildings in the City of Boston, including but not limited to, force majeure events, boycotts, strikes, embargoes or shortages. “Base Operating Expenses Allocable to the Premises” means the same proportion of Base Operating Expenses
as the Rentable Floor Area of Tenant’s Premises bears to the total Rentable Floor Area of the Office Area, plus the Rentable Floor Area of the Ground Floor Premises and, if applicable, the Rentable Floor Area of the BSC RFO Premises. As of the
Fourth Amendment Execution Date, the Rentable Floor Area of the Office Area is 709,348 square feet and the Rentable Floor Area of the Building is 947,974 square feet. The Office Area and the Retail Area shall not be remeasured during the Term except
in the event of changes thereto resulting from casualty and condemnation restoration. “Operating Expenses for the Office Area” means the cost of operation of the Office Area and the Office Area’s share of the cost of operating
other areas of the Project (exclusive of the Garage) as more specifically provided below, including those incurred in discharging Landlord’s repair obligations and services to be provided by Landlord under Article VI of the Lease; however there
shall be excluded from the Operating Expenses for the Office Area the cost of operation of the Garage and all expenses inuring solely to the benefit of the Retail Areas of the Project. If Landlord constructs the 201 Brookline Building, then
Operating Expenses incurred for the exterior areas of the Project shall be equitably allocated based on the Rentable Floor Area of the buildings, provided, however, no expenses that benefit solely the 201 Brookline Building, such as utility charges
and roof or building system repairs and maintenance for the 201 Brookline Building shall be included in Operating Expenses for the Office Area. In addition, such costs shall exclude payments of debt service and any other mortgage charges, brokerage
commissions, real estate taxes (to the extent paid pursuant to Section 9 hereof), and costs of special services rendered to tenants (including Tenant) for which a separate charge is made, but shall include, without limitation: 

(i) compensation, wages and all fringe benefits, workmen’s compensation insurance premiums and payroll taxes paid to, for
or with respect to all persons for their services in the operating, maintaining, managing or cleaning of the Office Area or the Project; 

  
 12 

 (ii) payments under service contracts with independent contractors for
operating, maintaining or cleaning of the Office Area or the Project; 
 (iii) steam, water, sewer, gas, oil, electricity and
telephone charges (excluding all charges for electricity and other utilities supplied to leasable areas of the Building and for which Tenant pays separately under the Lease or this Fourth Amendment); 

(iv) cost of maintenance, cleaning and repairs and replacements (other than repairs reimbursed from contractors under
guarantees); 
 (v) cost of snow removal and care of landscaping; 

(vi) cost of building and cleaning supplies and equipment; 

(vii) premiums for insurance carried with respect to the Office Area or the Project (including, without limitation, liability
insurance, insurance against loss in case of fire or casualty and of monthly installments of Annual Fixed Rent and any Additional Rent which may be due under this Lease and other leases of space in the Office Area for not more than twelve
(12) months in the case of both Annual Fixed Rent and Additional Rent and, if there be any first mortgage on the Office Area, including such insurance as may be required by the holder of such first mortgage) provided, however, with respect to
insurance coverages required to be carried by a holder of a mortgage such coverages are of the type and amounts customarily required to be carried by lenders of comparable buildings); 

(viii) management fees not to exceed [***] of Gross Receivable Rents for the Office Area (“Gross Receive file Rents for
the Office Area”) for the purposes hereof being defined as annual fixed rent, Landlord’s Operating Expenses (with the exception of the aforesaid management fee), payments on account of real estate taxes, and tenant electricity
reimbursements for the relevant year); 

  
 13 

 (ix) the Office Area’s share (as reasonably determined by Landlord) of
Operating Expenses related to the operation of the open areas, public areas and amenities, plazas, common areas, facilities and other non-leasable areas of the Project and other mixed use common area maintenance costs incurred by Landlord and
allocated to the Office Area and costs of operation (but not installation or fixturing) of the amenities operated by Landlord as of the Fourth Amendment Execution Date for use of tenants of the Office Area either alone or in common with tenants of
other buildings in the Project; provided, however, from and after the date that Landlord obtains a building permit for the construction of the 201 Brookline Building, Landlord’s Operating Expenses for the Office Area shall exclude all costs
related to the construction of the 201 Brookline Building; 
 (x) capital expenditures made by Landlord during the Term of
the Lease (1) to reduce Operating Expenses if Landlord shall have reasonably determined on the basis of independent, third party engineering estimates that the annual reduction in Operating Expenses shall exceed the annual depreciation therefor
or (2) to comply with Legal Requirements which first become applicable to the Building after the Third Extension Term Commencement Date (the capital expenditures described in subsections (1) and (2) being hereinafter referred to as
“Permitted Capital Expenditures”) plus, in the case of both (1) and (2), an interest factor, reasonably determined by Landlord, as being the interest rate then charged for long term mortgages by institutional lenders on like
properties within the general locality in which the Building is located, and depreciation in the case of both (1) and (2) shall be determined by dividing the original cost of such capital expenditure by the number of years of useful life
of the capital item acquired, which useful life shall be determined reasonably by Landlord in accordance with generally accepted accounting principles and practices in effect at the time of acquisition of the capital item; provided, however, if
Landlord reasonably concludes on the basis of independent, third party engineering estimates that a particular capital expenditure will effect savings in other Operating Expenses, including, without limitation, energy related costs, and that such
projected savings will, on an annual basis (“Projected Annual Savings”), exceed the annual depreciation therefor, then and in such event the amount of depreciation for such capital expenditure shall be increased to an amount equal
to [***] of the Projected Annual Savings; and in such circumstance, the increased depreciation (in the amount of [***] of the Projected Annual Savings) shall be made for such period of time as it would take to fully amortize the cost of the item in
question, together with interest thereon at the interest rate as aforesaid in equal monthly payments, each in the amount of 1/12th of [***] of the Projected Annual Savings, with such payment to be applied first to interest and the balance to
principal; and 
 (xi) all other reasonable and necessary expenses paid in connection with the operating, cleaning and
maintenance of the Office Area or the Project or said common areas and facilities and properly chargeable against income. 
 B. Gross
Up. Notwithstanding the foregoing, in determining the amount of Operating Expenses for the Office Area for any calendar year or portion thereof falling within the Term of the Lease, if less than the total Rentable Floor Area of the Office Area
shall have been occupied by tenants at any time during the period in question, then, at Landlord’s election but on a mandatory basis with respect to the calculation of the Base Operating Expenses, those components of Operating Expenses for the
Office Area that vary based on occupancy for such period shall be adjusted to equal the amount such components of Operating Expenses for the Office Area would have been for such period had occupancy been [***] throughout such period. 

  
 14 

 C. Exclusions from Operating Expenses. Notwithstanding the generality of
foregoing, the costs and expenses set forth on Exhibit L attached hereto shall be excluded or deducted, as the case may be, from the calculation of Operating Expenses Allocable to the Office Area. Notwithstanding anything in the Lease to the
contrary, to the extent that Landlord provides or procures services for the Building together with other buildings on the Project or in the same market area owned or otherwise operated by Landlord or any affiliate thereof, then the costs of such
services shall be allocated between the Building and such other buildings in a manner reasonably determined by Landlord and considering the rentable square footage of the buildings in the allocation. In no event shall Landlord collect from tenants
of the Office Area in excess of [***] of the actual Operating Expenses (plus the permitted amortization payments for Permitted Capital Expenditures set forth in Section 8(A)(x) above) incurred for the applicable calendar year. 

D. Tenant’s Escalation Payments. If with respect to any calendar year falling within the Term of the Lease, or fraction of a
calendar year falling within the Term of the Lease at the beginning or end thereof, the Operating Expenses Allocable to the Premises for a full calendar year exceed Base Operating Expenses Allocable to the Premises or for any such fraction of a
calendar year exceed the corresponding fraction of Base Operating Expenses Allocable to the Premises (such amount being hereinafter referred to as the “Operating Expenses Excess”), then Tenant shall pay to Landlord, as Additional
Rent, on or before the thirtieth (30th) day following receipt by Tenant of the statement referred to below in this Section 8, the amount of such Operating Expenses Excess. Payments by Tenant on account of the Operating Expenses Excess
shall be made monthly at the time and in the fashion herein provided for the payment of Annual Fixed Rent. The amount so to be paid to Landlord shall be an amount from time to time reasonably estimated by Landlord to be sufficient to cover, in the
aggregate, a sum equal to the Operating Expenses Excess for each calendar year during the Term of the Lease. Within [***] after the end of the first calendar year or fraction thereof ending December 31 and of each succeeding calendar year
during the Term of the Lease or fraction thereof at the end of the Term of the Lease, Landlord shall render Tenant a reconciliation statement in reasonable detail and according to usual accounting practices (the “Operating Expense
Statement”), showing for the preceding calendar year or fraction thereof, as the case may be, the Operating Expenses for the Office Area, the Base Operating Expenses, the Base Operating Expenses Allocable to the Premises and the Operating
Expenses Allocable to the Premises. Said statement to be rendered to Tenant also shall show for the preceding year or fraction thereof, as the case may be, the amounts already paid by Tenant on account of Operating Expenses Excess and the amount of
Operating Expenses Excess remaining due from, or overpaid by, Tenant for the year or other period covered by the statement. If such statement shows a balance remaining due to Landlord, Tenant shall pay same to Landlord on or before the thirtieth
(30th) day following receipt by Tenant of said statement. Any balance shown as due to Tenant shall be credited against Annual Fixed Rent next due, or refunded to Tenant if the Term of the Lease has then expired and Tenant has no further
obligation to Landlord. 
 Landlord’s failure to render or delay in rendering an Operating Expense Statement or annual electricity reconciliation
statement pursuant to Section 16 of this Fourth Amendment with respect to any calendar year, shall not prejudice Landlord’s right thereafter to render the same with respect thereto nor shall the rendering of an Operating Expense Statement
or annual electricity reconciliation statement, as applicable, for any calendar year, prejudice Landlord’s right thereafter to render a corrected Operating Expense Statement or annual electricity reconciliation statement, as applicable, for
such calendar year, provided, however, that Landlord shall in all events render the Operating Expense Statement or annual electricity reconciliation statement, as applicable, in question or any corrections thereto within [***] after the end of the
calendar year covered by the applicable statement. 

  
 15 

 E. Tenant’s Audit Right. Tenant shall have the right to examine the correctness
of any of the Landlord’s Operating Expense Statement, and/or any annual electricity reconciliation statement (“Electricity Statement”) or any item contained therein as follows: 

(1) Any request for examination in respect of any calendar year may be made by notice from Tenant to Landlord no more than [***] after the date
(the “Statement Date”) Landlord provides to Tenant the applicable year-end statement required hereunder in respect of such calendar year (and only if Tenant shall have fully paid the amounts billed with respect to the applicable
Operating Expenses or electricity charges), provided, however, such 180-day period shall be reinstated if Landlord issues any correction or adjusted Landlord’s Operating Expense Statement or Landlord’s Electricity Statement. 

(2) Except as set forth in this Section 8(E), Tenant hereby waives any and all other rights provided, including pursuant to applicable
laws to inspect Landlord’s books and records and/or to contest any Landlord’s Operating Expenses Statement and Landlord’s Electricity Statement. If Tenant shall fail to timely exercise Tenant’s right to inspect Landlord’s
books and records as provided in this Section 8(E), then such Operating Expense Statement and/or Electricity Statement, as applicable, shall be conclusive and binding on Tenant. 

(3) So much of Landlord’s books and records pertaining to the Landlord’s Operating Expenses and/or electricity charges, as
applicable, for the matters questioned by Tenant for the calendar year included in the applicable year end statement shall be made available to Tenant within [***] after Landlord timely receives the notice from Tenant to make such examination
pursuant to this Section 8(E), either electronically or during normal business hours at the offices where Landlord keeps such books and records or at another location, as determined by Landlord Any examination must be completed and the results
communicated to Landlord no later than [***] after the date Landlord makes its books and records available for Tenant’s audit. 
 (4)
Tenant shall have the right to make such examination no more than once in respect of any calendar year in which Landlord has given Tenant an Operating Expense Statement or Electricity Statement, as applicable. 

(5) Such examination may be made only by a qualified employee of Tenant or a qualified independent, real estate professional with at least ten
(10) years of relevant office leasing audit experience approved by Landlord, which approval in either case shall not be unreasonably withheld, conditioned or delayed. No examination shall be conducted by an examiner who is to be compensated, in
whole or in part, on a contingent fee basis. 

  
 16 

 (6) As a condition to performing any such Examination, Tenant and its examiners shall be
required to execute and deliver to Landlord an agreement, in form acceptable to Landlord, agreeing to keep confidential any information which it discovers about Landlord or the Building in connection with such examination. 

(7) If as a result of such examination it is determined that the amounts paid by Tenant to Landlord on account of the Landlord’s Operating
Expenses or electricity charges allocable to the Premises exceeded the amounts to which Landlord was entitled hereunder, or that Tenant is entitled to a credit with respect to the Landlord’s Operating Expenses, electricity charges, Landlord, at
its option, shall either refund to Tenant the amount of such excess, or apply the amount of such credit against Annual Fixed Rent and Additional Rent, as the case may be, within [***] after the date of such agreement, provided, however, that if the
Term of the Lease has expired, such amount shall be promptly refunded to Tenant. Similarly, if it is determined that the amounts paid by Tenant to Landlord on account of Landlord’s Operating Expenses or electricity charges, as applicable, were
less than the amounts to which Landlord was entitled hereunder, then Tenant shall pay to Landlord, as Additional Rent hereunder, the amount of such deficiency within [***] after the date of such agreement. 

(8) All costs and expenses of any such examination shall be paid by Tenant, except if as a result of such examination it is determined that the
amount of the Operating Expense Excess or electricity charges payable by Tenant was overstated by more than [***], Landlord shall reimburse Tenant for the actual, reasonable out of pocket costs and expenses incurred by Tenant in such examination, up
to a maximum of [***]. If as a result of such examination it is determined that the amount of the Operating Expense Excess or electricity charges payable by Tenant was overstated by more than [***], Tenant may elect to audit that line item of
Operating Expenses which was overcharged for the prior two (2) years. 
 9. Real Estate Taxes. Commencing as of January 1, 2020 and
continuing through the Third Extension Term, in lieu of a Tenant’s share of real estate taxes, Tenant shall pay to Landlord, monthly at the time and in the fashion provided for in the Lease for the payment of Annual Fixed Rent, the amounts set
forth below;

 10. Parking. 

A. Parking Privileges. The parties acknowledge that pursuant to Section VII of the Third Amendment, Tenant currently is entitled to
utilize two hundred (200) monthly parking privileges in the Garage (the “Existing Parking Allotment”). Effective as of each of the Area A Delivery Date, Area B Delivery Date, Fifth Floor Premises Delivery Date and Ground Floor
Premises Delivery Date, Landlord shall provide or cause Garage Tenant to provide Tenant with additional monthly parking privileges in the Garage on an unreserved basis for Tenant’s employees, for a ratio of up to two (2) parking spaces per
1,000 rentable square feet of the Premises then delivered to Tenant, such that after the occurrence of all of the foregoing delivery dates, Tenant shall be entitled to a total of three hundred ten (310) monthly parking privileges (the
“Initial Maximum Parking Allotment”) during the Term, as it may be extended. Tenant may elect to increase the number of its total parking privileges from time to time by up to an additional one-half (0.5) parking spaces per 1,000
rentable square feet of the Premises (i.e., up to an additional seventy-seven (77) monthly parking privileges) (the “Additional Parking Allotment”) upon not less than [***] prior written notice to Landlord. All of Tenant’s
parking privileges shall be subject to the terms and conditions of Section VII of the Third Amendment, unless otherwise expressly set forth in this Fourth Amendment. 

In addition, from time to time during the Term, Tenant may elect to reduce the number of parking privileges received by it by providing not
less than [***] prior notice of such reduction to Landlord. After any such election to receive less than the Initial Maximum Parking Allotment (or, if Tenant has previously so elected, the Additional Parking Allotment), Tenant may from time-to-time
request additional parking privileges back up to the Initial Maximum Parking Allotment (plus the Additional Parking Allotment if Tenant has so elected); provided, however (i) at no time shall Tenant be entitled to more parking privileges than
the Initial Maximum Parking Allotment (plus the Additional Parking Allotment if Tenant has so elected), and (ii) none of Landlord, Garage Tenant or Garage Operator shall have any obligation to provide such additional parking privileges unless
the Garage Operator determines in its reasonable good faith discretion that the requested number of parking privileges are then available in the Garage. 

The parties acknowledge that as part of the construction of the 201 Brookline Building (as defined in Section 14(A)), portions of the
Garage may be temporarily closed and some locations of access to and egress from the Garage will be temporarily closed, provided, however, Landlord shall not fully close the Garage and Tenant shall at all times have access to and use of the number
of parking privileges to which Tenant is entitled under this Fourth Amendment during such construction and at least one access and egress location in the Garage shall remain open throughout the construction of the 201 Brookline Building. Without
limiting Landlord’s express obligation to at all times provide Tenant with the number of parking privileges to which Tenant is entitled under this Fourth Amendment in the Garage, if at any time Tenant’s employees are denied entry into the
Garage for its full parking allotment under this Section 10, then, without limitation of Tenant’s other remedies under the Lease for such closure, Tenant’s monthly parking charges shall be abated (and refunded) for any days that
Tenant’s employees are denied entry into the Garage (but only for the number of parkers so denied entry). 

  
 18 

 B. Parking Charges. Tenant shall continue to pay for the number of parking privileges
from time to time subscribed for by Tenant from the Existing Parking Allotment at the rates set forth in Section VII of the Third Amendment through the date immediately preceding the Third Extension Term Commencement Date. Notwithstanding anything
to the contrary set forth herein or in the Lease, commencing as of the Third Extension Term Commencement Date with respect to the Existing Parking Allotment and ending on December 31, 2020, Tenant shall pay Garage Tenant or, if Garage Tenant so
directs, the Garage Operator for the number of parking privileges from time to time subscribed for by Tenant under this Section 8 at a rate of [***]. Commencing on January 1, 2021 and thereafter through the Third Extended Termination Date
Tenant shall pay Garage Tenant or, if Garage Tenant so directs, the Garage Operator for the number of parking privileges from time to time subscribed for by Tenant under this Section 8 at a rate equal to the prevailing monthly rates from time
to time charged by the Garage Operator for the Garage and the prevailing monthly rates for the Additional Garages (hereinafter defined). 

C. Alternative Facilities. Notwithstanding anything to the contrary set forth in the Lease, Landlord shall have the right, upon [***]
prior written notice to Tenant, to relocate, temporarily or permanently, up to [***] of Tenant’s parking privileges comprising the Initial Maximum Parking Allotment and the Additional Parking Allotment (such that Tenant’s ratio of monthly
parking privileges in the Garage shall not be less than [***] (the foregoing, the “Additional Garages”). In no event shall the parking charges payable by Tenant under the Lease for the parking privileges relocated to any of the
Additional Garages exceed the lesser of (i) the monthly parking rate in effect under Section 8(B) above for parking privileges in the Garage, or (ii) the prevailing monthly rate in effect for the applicable Additional Garage where the
parking privilege is located. 
 11. Extension Options. 

A. On the conditions (which conditions Landlord may waive by written notice to Tenant) that both at the time of the issuance of the Notice (as
hereinafter defined) and as of the commencement of the applicable Extension Term (as hereinafter defined), (i) there exists no Event of Default, (ii) the Lease is still in full force and effect, and (iii) Tenant has neither assigned
the Lease nor sublet more than [***] of the Premises in the aggregate and all for sublease terms that expire within twelve (12) months prior to the expiration date of the then current Term (excluding in all cases any Permitted Transfers),
Tenant shall have the right, subject to the terms and conditions set forth in this Section 11, to extend the Term of the Lease for two (2) periods of five (5) years each (each, an “Extension Term” and collectively,
the “Extension Terms”), commencing on January 1, 2030, and expiring on December 31, 2034 (the “Fourth Extension Term”), and commencing on January 1, 2035, and expiring on December 31, 2039 (the
“Fifth Extension Term”), respectively, at the Prevailing Market Rent. Notwithstanding any implication to the contrary Landlord has no obligation to make any additional payment to Tenant in respect of any construction allowance or
the like or to perform any work to the Premises as a result of the exercise by Tenant of any such option. 

  
 19 

 B. Tenant shall have the right to exercise the foregoing extension options for either, at
Tenant’s election, the entire Premises then leased or for only the Upper-Level Premises (which Upper-Level Premises shall for purposes of this Section 11B be deemed to include the Second Floor RFO Premises if Tenant has exercised the
Second Floor RFO Right). Tenant shall specify in the applicable Extension Notice whether Tenant has elected to extend the Term for all of the Premises or only the Upper-Level Premises; provided, however if Tenant does not do so, then Tenant will be
considered to have elected to extend the Term for the entire Premises. If Tenant exercises an extension option for only the Upper-Level Premises, then on the date immediately preceding the first day of the applicable Extension Term, Tenant shall
surrender to Landlord possession of the remainder of the Premises then leased to Tenant which does not constitute the Upper-Level Premises (such portion, the “Extension Surrender Space”), free and clear or all occupants, vacant and
free of any lien or encumbrance created by Tenant or persons claiming by, through or under Tenant and otherwise in the condition required in accordance with the provisions of the Lease. On the date immediately preceding the first day of the
applicable Extension Term (such date, the “Extension Surrender Date”), Tenant’s lease of the Extension Surrender Space shall end and expire, and Tenant’s estate in and possession of the Extension Surrender Space shall
terminate and be extinguished as if the Extension Surrender Date were the Third Extended Termination Date with respect thereto. From and after the Extension Surrender Date, Tenant’s Proportionate Share and the monthly parking privileges shall
be reduced on a pro rata basis to reflect the removal of the Extension Surrender Space from the Premises. If Tenant fails to surrender to Landlord possession of the Extension Surrender Space on the Extension Surrender Date, in the condition
required, then Tenant shall be in holdover in the Extension Surrender Space and Landlord shall have the right to exercise any of Landlord’s rights and remedies at law and in equity (including, without limitation, pursuant to Section 14.12
of the Lease). 
 C. If Tenant desires to extend the Fourth Extension Term, then Tenant shall give notice (an “Exercise
Notice”) to Landlord, on or before July 1, 2028. If Tenant desires to extend the Fifth Extension Term, then Tenant shall give an Exercise Notice to Landlord, on or before July 1, 2033. Not later than the later of (i) [***]
after Landlord’s receipt of Tenant’s Exercise Notice, and (ii) the date which is [***] prior to the expiration date of the then current Term, Landlord shall provide Landlord’s quotation to Tenant of a proposed Annual Fixed Rent
for the applicable Extension Term (“Landlord’s Rent Quotation”). If at the expiration of thirty (30) days after the date when Landlord provides such quotation to Tenant (the “Negotiation Period”), Landlord
and Tenant have not reached agreement on a determination of an Annual Fixed Rent for such Extension Term and executed a written instrument extending the Term of this Lease pursuant to such agreement, then Tenant shall have the right, for [***]
following the expiration of the Negotiation Period, to make a request to Landlord for a broker determination (the “Broker Determination”) of the Prevailing Market Rent (as defined in Exhibit K) for such Extension Term, which
Broker Determination shall be made in the manner set forth in Exhibit K. If Tenant timely shall have requested the Broker Determination, then the Annual Fixed Rent for such Extension Term shall be the Prevailing Market Rent as determined by
the Broker Determination. If Tenant does not timely request the Broker Determination, then the Annual Fixed Rent during the applicable Extension Term shall be equal to Landlord’s Rent Quotation. 

D. Upon the giving of the Exercise Notice by Tenant to Landlord exercising Tenant’s applicable option to extend the Term in accordance
with the provisions of Section 11(B) above, then this Lease and the Term hereof shall automatically be deemed extended, for the applicable Extension Term, without the necessity for the execution of any additional documents, except that Landlord
and Tenant agree to enter into an instrument in writing setting forth the Annual Fixed Rent for the applicable Extension Term as determined in the relevant manner set forth in this Section 11; and in such event all references herein to the
Lease Term or the Term of this Lease shall be construed as referring to the Term, as so extended, unless the context clearly otherwise requires, and except that there shall be no further option to extend the Term beyond the second Extension Term.
Notwithstanding anything contained herein to the contrary, in no event shall Tenant have the right to exercise more than one option to extend the Term at a time and, further, Tenant shall not have the right to exercise its right to extend the Term
of the Lease for the Fifth Extension Term unless it has duly exercised its right to extend the Term of the Lease for the Fourth Extension Term. 

  
 20 

 E. If as of the commencement of any Extension Term, Tenant is then subleasing more than
[***] of the Ground Floor Premises (except in all cases for Permitted Transfers), then Landlord shall have the right upon notice delivered to Tenant within [***] of Tenant’s delivery of the applicable Extension Notice, to terminate the Term of
the Lease only with respect to the Ground Floor Premises, which termination shall be effective as of the commencement of the applicable Extension Term. Upon the giving of such notice, the Term of the Lease with respect to the Ground Floor Premises
only shall terminate as of said commencement of the applicable Extension Term, and Annual Fixed Rent, Additional Rent, monthly parking privileges and other charges due under the Lease shall be apportioned as of said commencement of the applicable
Extension Term. Thereafter, the Lease solely with respect to the Ground Floor Premises and the rights of the Tenant solely with respect thereto shall terminate and expire with the same force and effect as if such commencement of the applicable
Extension Term had originally been specified as the Third Extended Termination Date, and the provisions of Section 14(F)(iv)-(vii) below shall apply to the Ground Floor Premises. 

12. Right of First Offer for Boston Sports Club Premises. 

A. So long as the Lease is in full force and effect, and subject to the BSC RFO Conditions (as hereinafter defined) and which conditions
Landlord may waive, in its sole and absolute discretion, at any time, but only by written notice to Tenant, Tenant shall have the one-time right (the “BSC RFO Right”) to lease the BSC RFO Premises, as hereinafter defined, when the
BSC RFO Premises become available for lease, as hereinafter defined. The “BSC RFO Conditions” are that (i) there exists no monetary or material nonmonetary Event of Default at the time that Landlord delivers Landlord’s BSC

for the Upper-Level Premises, it being the intent of Landlord and Tenant that the Annual Fixed Rent rate per rentable square foot in effect for the BSC RFO Premises shall always be the same as the Annual Fixed Rent rate per rentable square foot in
effect for the Upper-Level Premises for the corresponding period. 

  
 22 

 (iii) Condition of BSC RFO Premises. Landlord shall deliver the BSC
RFO Premises to Tenant and Tenant shall lease the BSC RFO Premises in the shell condition, more particularly described on Exhibit J-3, attached hereto and in the Delivery Condition. Landlord shall provide a tenant improvement allowance for

and in accordance with the provisions of Section VII of the Third Amendment and Section 10 of this Fourth Amendment, except that Landlord shall not have the right to relocate the parking privileges comprising the BSC RFO Parking Allotment and
the provisions of Section 10(C) of this Fourth Amendment shall not apply thereto, except that Landlord may temporarily relocate such parking privileges to the Additional Garages during any renovation or redevelopment of the Project. 

E. Notwithstanding the fact that Tenant’s exercise of the above-described option to lease the BSC RFO Premises shall be self-executing,
as aforesaid, the parties hereby agree promptly to execute a lease amendment reflecting the addition of the BSC RFO Premises. The execution of such lease amendment shall not be deemed to waive any of the conditions to Tenant’s exercise of the
herein option to lease the BSC RFO Premises, unless otherwise specifically provided in such lease amendment. 
 F. Except as set forth in
this Section 12(F), Landlord shall not be liable for any failure to deliver the BSC RFO Premises by any particular date, no such failure shall impair the validity of the Lease or extend the Term. Notwithstanding the foregoing or any provision
contained herein to the contrary, if the BSC RFO Premises Commencement Date has not occurred by the date which is [***] after the Estimated BSC RFO Commencement Date (as such date may be extended for Tenant Delays and/or Force Majeure, the

notwithstanding the foregoing or any provision contained herein to the contrary, it the BSC RFO Premises Commencement Date has not occurred by the date which is [***] after the Estimated BSC RFO Commencement Date (as such date may be extended for
Tenant Delays and/or Force Majeure, the “BSC RFO Premises Termination Date”), then Tenant may elect, as its sole and exclusive remedy on account thereof, to rescind Tenant’s BSC Exercise Notice by giving Notice thereof to
Landlord after the BSC RFO Premises Termination Date, whereupon Tenant’s BSC Exercise Notice shall be deemed rescinded and of no further force or effect. Notwithstanding anything to the contrary contained herein, the Outside BSC RFO Premises
Commencement Date and BSC RFO Premises Termination Date shall be extended, and there shall be no credit against Annual Fixed Rent for any delay in the occurrence of the BSC RFO Premises Commencement Date or the BSC RFO Premises Termination Date
arising out of or resulting from any Tenant Delay and/or Force Majeure.

relocate the parking privileges comprising the Second Floor RFO Parking Allotment and the provisions of Section 10(C) of this Fourth Amendment shall not apply thereto, except that Landlord may temporarily relocate such parking privileges to the
Additional Garages during any renovation or redevelopment of the Project. 
 E. Notwithstanding the fact that Tenant’s exercise of the
above-described option to lease the Second Floor RFO Premises shall be self-executing, as aforesaid, the parties hereby agree promptly to execute a lease amendment reflecting the addition of the Second Floor RFO Premises to the Premises. The
execution of such lease amendment shall not be deemed to waive any of the conditions to Tenant’s exercise of the herein option to lease the Second Floor RFO Premises, unless otherwise specifically provided in such lease amendment.

 F. Notwithstanding anything to the contrary contained herein, if (i) Tenant was
entitled to exercise its Second Floor RFO Right but failed to deliver a Tenant’s Second Floor Exercise Notice within the fifteen (15) business day period as provided in Section 13(C) above, and (ii) thereafter prior to entering
into a lease (or leases) for such Second Floor RFO Premises Landlord proposes to lease the Second Floor RFO Premises to a prospective third-party tenant on terms that are “materially more favorable” than those set forth in the
Landlord’s Second Floor Notice previously delivered to Tenant, then Tenant’s rights with respect to the Second Floor RFO Premises shall be revived and Tenant shall once again have a Second Floor RFO Right with respect to the Second Floor
RFO Premises. For purposes hereof, the terms offered to a prospect shall be deemed to be “materially more favorable” from those set forth in the Landlord’s Second Floor Notice if there is a reduction of more than [***] in the
“net effective rent” per rentable square foot of the Second Floor RFO Premises to the prospective tenant, when compared with the “net effective rent” per rentable square foot for the Second Floor RFO Premises under the
Landlord’s Second Floor Notice, determined by considering all of the economic terms of both proposals. 
 G. Except as set forth in
this Section 13(G), Landlord shall not be liable for any failure to deliver the Second Floor RFO Premises by any particular date, no such failure shall impair the validity of the Lease or extend the Term. Notwithstanding the foregoing or any
provision contained herein to the contrary, if the Second Floor RFO Premises Commencement Date has not occurred by the date which is [***] after the Estimated Second Floor RFO Commencement Date (as such date may be extended for Tenant Delays and/or
Force Majeure, the “Outside Second Floor RFO Premises Commencement Date”), then for and with respect to each day between tide Outside Second Floor RFO Commencement Delivery Date and the date on which the Second Floor RFO Premises
Commencement Date actually occurs, as its sole and exclusive remedy on account thereof, Tenant shall receive a credit against the Annual Fixed Rent next becoming payable under the Lease for the Second Floor RFO Premises in an amount equal to the per
diem Annual Fixed Kent payable for the Second Floor RFO Premises. In addition, notwithstanding the foregoing or any provision contained herein to the contrary, if the Second Floor RFO Premises Commencement Date has not occurred by the date which is
[***] after the Estimated Second Floor RFO Commencement Date (as such date may be extended for Tenant Delays and/or Force Majeure, the “Second Floor RFO Premises Termination Date”), then Tenant may elect, as its sole and exclusive
remedy on account thereof, to rescind Tenant’s Second Floor Exercise Notice by giving Notice thereof to Landlord after the Second Floor RFO Premises Termination Date, whereupon Tenant’s Second Floor Exercise Notice shall be deemed
rescinded and of no further force or effect. Notwithstanding anything to the contrary contained herein, the Outside Second Floor RFO Premises Commencement Date and the Second Floor RFO Premises Termination Date shall be extended, and there shall be
no credit against Annual Fixed Rent for any delay in the occurrence of the Second Floor RFO Premises Commencement Date or the Second Floor RFO Premises Termination Date arising out of or resulting from any Tenant Delay and/or Force Majeure.

Lease Negotiation Period (as it may be extended or shortened as provided in this Section 14), then Tenant shall be deemed to have rejected the option to lease the 201 Brookline RFO Premises and Tenant shall have no further rights or claims
thereto, provided, however, the foregoing shall not waive Tenant’s rights or remedies on account of any default of Landlord under the Lease, including this Section 14.

liabilities and obligations of Tenant under the Lease (i) with respect to the Surrender Space, which accrue or arise prior to the Partial Surrender Date or (ii) with respect to the remaining Premises. 

(vi) Without limiting the foregoing, if Tenant fails to yield up and surrender the Surrender Space by the Ground Floor/BSC
Effective Surrender Date, then for and with respect each day between the Ground Floor/BSC Effective Surrender Date and the Partial Surrender Date, Tenant shall pay a holdover charge at the rate set forth in the Lease. Nothing herein contained shall
constitute a release, waiver, limitation, or restriction of any rights or remedies of Landlord on account of Tenant’s failure to surrender the Surrender Space by the Ground Floor/BSC Effective Surrender Date. 

(vii) The Annual Fixed Rent, Tenant’s Proportionate Share and the monthly parking privileges shall be reduced as of the
Partial Surrender Date to an amount which shall reflect the deletion of the Surrender Space from the Premises, and Landlord and Tenant shall enter into an amendment of the Lease to reflect the foregoing within [***] of the date on which the Ground
Floor/BSC Surrender Notice shall have been delivered to Landlord, provided that the effectiveness of such amendment shall be conditioned upon Tenant’s payment to Landlord of the Ground Floor/BSC Effective Surrender Fee. 

(viii) Time is of the essence of this Section 14(F). 

  
 31 

 H. Landlord’s Ground Floor/BSC Termination Right. If Tenant has exercised the
201 Brookline RFO Right then Landlord shall have the right upon notice delivered to Tenant within [***] of Tenant’s delivery of Tenant’s 201 Brookline RFO Exercise Notice, to terminate the Term of the Lease only with respect to the
Surrender Space, which termination shall be effective as of the date (the “Effective Recapture Date”), which is the delivery of the 201 Brookline RFO Premises to Tenant or, at Tenant’s election, [***] after the
201 Brookline RFO Commencement Date. Upon the giving of such notice, the Term of the Lease with respect to the Surrender Space only shall terminate as of said Effective Recapture Date, and Annual Fixed Rent, Additional Rent, monthly parking
privileges and other charges due under the Lease shall be apportioned as of said Effective Surrender Date. Thereafter, the Lease solely with respect to the Surrender Space and the rights of the Tenant solely with respect thereto shall terminate and
expire with the same force and effect as if such Effective Recapture Date had originally been specified as the Third Extended Termination Date, and the provisions of Section 13(F)(iv)-(vii) shall apply to the Surrender Space. 

I. Tenant’s Leasing or Subleasing of Additional Space. If Tenant satisfied the 201 Brookline RFO Conditions but was unable to
exercise the 201 Brookline RFO Right as a result of (1) the Landlord not proceeding with construction of the 201 Brookline Building by the date which is two (2) years after the Execution Date of this Fourth Amendment, as evidenced by the
issuance of a building permit for the 201 Brookline Building, or (2) Landlord delivering Landlord’s Single Tenant Notice, then, in the event that Tenant elects to take an assignment of an existing lease or to sublease space from another
tenant in the Building or the 201 Brookline Building, Landlord agrees that, so long as such proposed sublease space or assigned lease does exceed 25,000 rentable square feet in the aggregate, (i) Landlord will not withhold its consent to any
such assignment or sublease on the basis that Tenant is already a tenant in the Building or the 201 Brookline Building and (ii) Landlord will not exercise any termination or recapture right for the applicable space in the Building or the
201 Brookline Building that is proposed to be assigned or subleased to Tenant. 
 15. Tenant’s Early Termination Option 

A. So long as the Lease is in full force and effect, and subject to the Termination Conditions (as hereinafter defined), and which Landlord
may waive, in its sole and absolute discretion, at any time, but only by notice to Tenant, Tenant shall have the right and option (the “Termination Right”) to terminate the Term of the Lease for the entire Premises effective on any
date (the “Effective Termination Date”) which is specified in Tenant’s Termination Notice and is after December 31, 2026, provided that (i) Tenant gives Landlord prior written notice (“Tenant’s
Termination Notice”) on or before the date which is [***] prior to the Effective Termination Date and (ii) Tenant pays Landlord the Termination Fee, as hereinafter defined, to Landlord at the time that Tenant gives Tenant’s
Termination Notice to Landlord. The “Termination Conditions” are that there then exists no monetary or material non-monetary Event of Default at the time that Tenant delivers Tenant’s Termination Notice or on the Effective
Termination Date. Notwithstanding anything to the contrary contained in the Lease, if Tenant exercises the 201 Brookline RFO Right and actually is delivered possession of the 201 Brookline RFO Premises, Tenant’s Termination Right shall be null
and void and of no further force or effect. An initial sample calculation of the Termination Fee is attached hereto as Exhibit O and based on the earliest possible Effective Termination Date. Not more than twice during the Term and also
following Tenant’s exercise of any right of first offer hereunder, Landlord shall provide Tenant with the amount of and reasonably detailed back-up documentation for the Termination Fee within [***] following receipt of a written request from
Tenant and provision of a proposed termination date. 

  
 32 

 B. The “Termination Fee” shall be equal to the Unamortized Portion of
Landlord’s Termination Costs, as hereinafter defined. The “Unamortized Portion” shall be defined as the amount of principal which would remain unpaid as of the Effective Termination Date with respect to a theoretical loan in an
original principal amount equal to Landlord’s Termination Costs and which is repaid in equal monthly payments of principal and interest on a direct reduction basis over the Third Extension Term (or such shorter term with respect to any premises
leased by Tenant under Sections 12 and/or 13 of this Fourth Amendment) with interest at the rate of [***] per annum. “Landlord’s Termination Costs” shall mean the sum of (I) the Fourth Amendment Allowances, and brokerage
commissions paid in connection with this Fourth Amendment, plus (II) if Tenant exercises either or both of the BSC RFO Right and/or the Second Floor RFO Right the Unamortized Portion of all costs and expenses incurred by Landlord in connection with
tenant improvement allowances and brokerage commissions paid by Landlord in connection with BSC RFO Premises and the Second Floor RFO Premises. 

C. Provided that all of the Termination Conditions have been fully and completely and timely satisfied, then effective as of the Effective
Termination Date, the Lease, and the rights of the Tenant with respect to the Premises, shall terminate and expire with the same force and effect as if such Effective Termination Date had been the Third Extended Termination Date. Prior to the later
of (such later date, the “Full Premises Surrender Date”) (i) the Effective Termination Date, and (ii) the date on which Tenant actually surrenders and yields-up the Premises, Tenant shall comply with all of the terms and
provisions of the Lease and shall perform all of its obligations hereunder, including, without limitation, the obligation to pay when due all Annual Fixed Rent and other Additional Rent. By not later than the Effective Termination Date, Tenant shall
surrender and yield-up the Premises in good and broom-clean order, repair and condition, free of all tenants and occupants, and otherwise in the condition in which the Premises are required to be surrendered, subject to and in accordance with the
provisions of the Lease at the expiration of the Term. All property and alterations of any kind, nature or description remaining in the Premises after the Full Premises Surrender Date shall be and become the property of Landlord and may be disposed
of by Landlord, without payment from Landlord and without the necessity to account therefor to Tenant. 
 D. Effective as of the Full
Premises Surrender Date, Landlord shall be released from any and all obligations and liabilities thereafter accruing under the Lease. Nothing contained herein shall constitute a waiver, limitation, amendment, or modification of any of the
liabilities and obligations of Landlord under the Lease which accrue or arise prior to the Full Premises Surrender Date. Effective as of the Full Premises Surrender Date, Tenant shall be released from any and all liabilities and obligations
thereafter accruing under the Lease. Nothing contained herein shall constitute a waiver, limitation, amendment, or modification of any of the liabilities and obligations of Tenant under the Lease which accrue or arise prior to the Full Premises
Surrender Date. 
 E. Without limiting the foregoing, if Tenant fails to yield up and surrender the Premises by the Effective Termination
Date, then for and with respect each day between the Effective Termination Date and the Full Premises Surrender Date, Tenant shall pay a holdover charge at the rate set forth in the Lease. Nothing herein contained shall constitute a release, waiver,
limitation, or restriction of any rights or remedies of Landlord on account of Tenant’s failure to surrender the Premises by the Effective Termination Date. 

  
 33 

 F. Time is of the essence with respect to Tenant’s Termination Right pursuant to this
Section 15. 
 16. Tenant Electricity. The Premises are separately metered or submetered for electricity measuring electrical service for
lights and plugs (exclusive of electricity for base building HVAC service to the Premises which shall be included in Landlord’s Operating Expenses Allocable to the Office Area), and, from and after the applicable dates set forth in this Fourth
Amendment, Tenant shall pay Landlord, as additional rent, for electricity in the Premises, periodically as billed by Landlord (but not more than monthly), based on the amount of electricity consumed by Tenant as measured by such submeter and the
rate charged therefor by the utility company, without mark-up by Landlord. As of the date of this Fourth Amendment, Tenant’s use of HVAC service in the Premises after Normal Business Hours is measured by one or more submeters measuring
Tenant’s usage of hot and chilled water. Tenant shall pay the charge for HVAC consumed after Normal Business Hours (“after-hours HVAC service”), as measured by said submeter(s) (“HVAC Charge”) as hereinafter provided.
Tenant shall pay Landlord, as additional rent, the HVAC Charge, periodically as billed by Landlord (but not more than monthly), based on the amount of after-hours HVAC service consumed by Tenant as measured by such submeters. Effective as of the
date that this Section 16 applies to an applicable portion of the Premises, the overtime HVAC charges set forth in Section 5.2 of the Existing Lease shall no longer apply. 

17. Tenant Signage. 
 A. Landlord
shall provide building standard signage in the standard graphics for the Building listing Tenant on all tenant directory(ies) for the Office Area. The initial listing of Tenant’s name shall be at Landlord’s expense. Any changes or
additions to such directory(ies) shall be at Tenant’s cost and expense at the building standard rate charged from time to time to tenants of the Office Area. Tenant may install signage identifying Tenant, which may include Tenant’s
corporate logo and colors, on the entrance door to the Premises and in the elevator lobbies on floors leased in whole or in part by Tenant and/or within the Premises, which signage shall be subject to Landlord’s approval, which approval shall
not be unreasonably withheld, conditioned or delayed. If during the Term Landlord installs any digital display boards or signage at the Building which displays the names and/or logos of other tenants or occupants at the Building, then Tenant shall
also have the right to be displayed on such digital display boards or signs (with display time proportionate to the Rentable Floor Area leased by the tenants thereon) on the same terms and conditions. 

B. Landlord is currently designing lobby signage for tenants in the Office Area. Tenant shall have the non-exclusive right to lobby signage in
the Office Area, which shall consist of one of the lobby signs designed by Landlord in a location to be designated by Landlord in the so-called “East Lobby” on the second (2nd) floor of the Office Area and containing the name and/or
logo of Tenant (the “Lobby Sign”), so long as the Lobby Sign Conditions are satisfied. The size of the Lobby Sign and the design, colors and appearance of Tenant’s name and/or logo on such Lobby Sign shall be mutually agreed
upon by Landlord and Tenant. The Lobby Sign shall be installed by Landlord at Tenant’s sole cost and expense. The “Lobby Sign Conditions” are: (a) the Lease is in full force and effect, (b) [Intentionally Deleted],
(c) the Lobby Sign is in compliance with all applicable Legal Requirements, (d) the fabrication, installation, maintenance and removal of such Lobby Sign is performed at Tenant’s expense in accordance with the terms and conditions
governing alterations in the Lease, (e) the Premises is operating as Tenant’s headquarters, and (f) Tenant (together with any occupants pursuant to Permitted Transfers) is occupying at least 110,000 rentable square feet in the Office
Area. Notwithstanding anything to the contrary contained in the Lease, within [***] after the date on which (i) the Lease is no longer in full force and effect; (ii) Tenant or occupants pursuant to Permitted Transfers no longer occupy at
least 110,000 rentable square feet in the Office Area, (iii) the Premises ceases to be Tenant’s headquarters, or (iv) the Term of the Lease expires or is terminated, then Tenant shall, at its cost and expense, remove the Lobby Sign
and repair all damage to the Building caused by the installation and/or removal of the Lobby Sign. The right to the Lobby Sign granted pursuant to this Section 17(B) is personal to Tenant and may not be exercised by any occupant, subtenant or
assignee of Tenant, except for assignees or subtenants pursuant to Permitted Transfers. 

  
 34 

 18. Assignment and Subletting. 

A. Article X (Assignment and Subletting) of the Existing Lease (as amended by Section 9(B)(ii) of the Third Amendment) is hereby amended
to delete the second paragraph of Section 9(B) of the Third Amendment and replace the same with the following provision: 

“(1) Tenant’s Notice; Landlord’s Recapture Right. In the event Tenant desires to (a) assign this
Lease, or (b) to enter into a Major Sublease, as hereinafter defined, Tenant shall give Landlord either (y) a written notice of the proposed sublease or assignment (a “Proposed Transfer Notice”) in the event Tenant already
has a specific assignment or sublease transaction or (z) a written notice stating that Tenant is contemplating entering into an assignment or Major Sublease (either such notice being hereinafter referred to as a “Notice of Intent to
Transfer”) and Landlord shall have the right (“Landlord’s Recapture Right”) at its sole option, to be exercised (1) [***] after receipt of Tenant’s Notice of Intent to Transfer, or (2) within [***] after
receipt of Tenant’s Proposed Transfer Notice (such response time period, as applicable to the type of notice received from Tenant, being referred to herein as the “Acceptance Period”), to terminate the Lease and recapture all
or a portion of the Premises as follows and subject to clause (4) below: (I) in the event of a proposed assignment of the Lease, to terminate the Lease, (II) in the event of a proposed Major Ground Floor/BSC Sublease (as hereinafter
defined), to terminate the Lease with respect to the Ground Floor Premises or the BSC RFO Premises, as applicable, (III) in the event of a proposed Major Full Term Sublease (as hereinafter defined), to terminate the Lease with respect to the portion
of the Premises proposed to be sublet, or (IV) in the event of a proposed Major Partial Term Sublease (as hereinafter defined), to terminate the Term of the Lease for the portion of the Premises proposed to be sublet for the term of the proposed
Major Partial Term Sublease (such portion of the Premises to be terminated pursuant to clause (I)-(IV), the “Recaptured Premises”). In each case, such termination shall be effective as of the Tenant’s proposed effective date of
such assignment or sublease, as if such date were the last day of the Term of this Lease, provided, however, if Landlord exercises the rights under this Section to terminate this Lease in connection with a proposed sublease of a portion of the
Premises, this Lease shall be deemed amended to eliminate the Recaptured Premises from the Premises as of the termination date, and thereafter the Annual Fixed Rent and Additional Rent shall be appropriately prorated to reflect the reduction of the
Premises as of such termination date and, until such time, if at all, that the Term of the Lease recommences as to such Recaptured Premises and any such termination in connection with a Major Sublease shall be subject to any rights of Tenant
expressly contained in the Tenant’s Notice of Intent to Transfer or Proposed Transfer Notice, as applicable, to terminate the sublease term early (in which case Landlord shall comply with Tenant’s election to have the Recaptured Premises
released to Tenant as of such earlier date, if exercised), which right and obligation of Tenant shall expressly survive such termination. 

  
 35 

 (2) Major Sublease. A “Major Ground Floor/BSC
Sublease” shall mean a sublease pursuant to which Tenant will sublet more than [***] of the Rentable Floor Area of either the Ground Floor Premises or the BSC RFG Premises for a sublease term of more than three (3) years or that
expires during the last three (3) years of the then current Term. A “Major Full Term Sublease” shall mean a sublease pursuant to which Tenant will sublet (i) any portion of either the Fifth Floor Premises or Second Floor
RFG Premises which is or will be separately demised for a sublease term that will expire within twelve (12) months prior to the expiration date of the then current Term, or (ii) more than [***] of the Rentable Floor Area of the Eighth
Floor Premises (either alone or together with any prior subleases) which is or will be separately demised for a sublease term that will expire within twelve (12) months prior to the expiration date of the then current Term. A “Major
Partial Term Sublease” shall mean a sublease pursuant to which Tenant will sublet more than [***] of the Rentable Floor Area of either of the Fifth Floor Premises or Second Floor RFO Premises (either alone or together with any prior
subleases) which is or will be separately demised for a sublease term of more than four (4) years. A “Major Sublease” shall mean any of a Major Ground Floor/BSC Sublease, Major Full Term Sublease or Major Partial Term Sublease.

 (3) Conditions Applicable to Recapture of Major Partial Term Subleases. If Landlord exercises its rights under this
Article X to terminate the Term of the Lease with respect to a Major Partial Term Sublease for the term of the applicable Major Partial Term Sublease, then Landlord may lease the Recaptured Premises for the term of such recapture only to an existing
tenant of the Building or an affiliate of an existing tenant of the Building. 

  
 36 

 (4) Conditions Applicable to Recapture of all Major Subleases. If
Landlord exercises its rights under this Article X to terminate the Term of the Lease with respect to a Major Sublease, then (i) Landlord’s termination of this Lease and Landlord’s re-leasing of the Recaptured Premises shall be
subject to any rights of Tenant expressly contained in Tenant’s Notice of Intent to Transfer or Tenant’s Proposed Transfer Notice, as applicable, to terminate the sublease term early (in which case Landlord shall comply with Tenant’s
election to have the Recaptured Premises released to Tenant as of such earlier date, if exercised); provided, however, if Tenant’s Notice of Intent to Transfer contains a right of Tenant to terminate the sublease term early and Landlord does
not exercise Landlord’s Recapture Right with respect to such Notice of Intent to Transfer, then in the event that Tenant intends to enter into a Major Sublease for such portion of the Premises identified in Tenant’s previous Notice of
Intent to Transfer with no right of Tenant to terminate the sublease term early or with a materially later date for such early termination, then Tenant must deliver a Proposed Transfer Notice with respect thereto and Landlord shall at such time
again have a Landlord’s Recapture Right with respect to such Proposed Transfer Notice, (ii) Landlord and Tenant will share equally in the cost to demise the Recaptured Space:, except that Landlord pays [***] of the cost to demise if the
proposed subtenant was required to pay such costs pursuant to the proposed sublease delivered with Tenant’s Proposed Transfer Notice or pursuant to Tenant’s Notice of Intent to Transfer, (iii) Landlord will not enter into a lease for
the Recaptured Premises with a Tenant Competitor, as hereinafter defined, so long as Tenant continues to occupy space on the same floor of the Office Area as the Recaptured Premises, (iv) any demising partitions and common areas that need to be
constructed to demise the Recaptured Premises shall be entirely accommodated within the Recaptured Premises and shall not decrease the usable square footage of the portion of the Premises retained by Tenant, (v) Landlord shall indemnify, defend
and hold Tenant harmless from and against any accident, injury or damage whatsoever to any person, or to the property of any person, occurring in the Recaptured Premises after Tenant’s delivery of possession to Landlord through the end of the
Term of this Lease (which obligation shall survive the expiration or termination of this Lease with respect to claims occurring during such period); and (vi) Landlord or its assignee or subtenant shall, unless Tenant agrees otherwise, restore
the Recaptured Premises to the same condition in which the Recaptured Premises was delivered to Landlord, including restoration of all improvements and other Alterations, reasonable wear and tear excluded, and return such Recaptured Premises to
Tenant at the expiration of the term Tenant proposed to sublease the same for. If Landlord fails to deliver such Recaptured Premises in the required condition on or before such re- delivery date, then for each day that Landlord fails to deliver such
Recaptured Premises in the required condition after such re-delivery date, Tenant shall be entitled to a rent credit against the Base Rent payable under this Lease for the remainder of the Premises equal to the greater of (1) [***] of the daily
Base Rent otherwise payable hereunder on account of the Recaptured Premises, and (2) the amount of fixed or base rent (and any holdover premium) collected by Landlord for any occupant of the Recaptured Premises. A “Tenant
Competitor” shall mean a person or entity principally and primarily engaged, directly or indirectly (including through any partnership, limited liability company, corporation, joint venture or similar arrangement (whether now existing or
formed hereafter)) in the restaurant point of sale business. 

  
 37 

 (5) Landlord’s recapture and/or termination rights under this Article X
shall not be applicable to any transaction constituting a Permitted Transfer and the rentable square footage of any transaction constituting a Permitted Transfers shall not be counted in determining any assignment or sublease thresholds set forth in
the Lease, provided that following any Permitted Transfer Landlord’s Recapture Right shall continue to apply to any future assignment or Major Sublease that does not qualify as a Permitted Transfer on the terms set forth herein. Notwithstanding
anything herein to the contrary, if Landlord fails to exercise Landlord’s Recapture Right under this Lease with respect to a Notice of Intent to Transfer within the Acceptance Period, Landlord will not thereafter have the right to exercise
Landlord’s Recapture Ri girt with respect to a Proposed Transfer Notice for any portion of the space identified in Tenant’s previous Notice of Intent to Transfer provided Tenant’s Proposed Transfer Notice is received within [***]
following Landlord’s receipt of the Notice of Intent to Transfer. In the event Landlord exercises its rights under this Article X to terminate the Lease as to the Recaptured Premises, then Tenant may elect to rescind its request for consent to
the proposed assignment or sublease by notice to Landlord within [***] following Landlord’s delivery of written notice to Tenant exercising the Landlord’s Recapture Right, and, in the event of such rescission, then Tenant’s Notice of
Intent to Transfer or Tenant’s Proposed Transfer Notice, as applicable, and Landlord’s exercise of the Landlord’s Recapture Right shall be rescinded and revoked and of no further force or effect and the Term of this Lease shall remain
in full force and effect. 
 (6) If Landlord exercises Landlord’s Recapture Right pursuant to the foregoing provisions,
then (1) this Lease shall end and expire with respect to the Recaptured Premises on the Tenant’s proposed effective date of such assignment or sublease, but only until such time, if at all, that the Term of the Lease recommences as to such
Recaptured Premises in which event this Lease shall commence as to the Recaptured as of the date Landlord delivers possession of the Recaptured Premises to Tenant in the condition required under this Article X (and subject to any holdover amounts
due to Tenant under this Article X), (2) Annual Fixed Rent, additional rent and electricity charges shall be apportioned, paid, or refunded as of such date, (3) Annual Fixed Rent, Tenant’s Proportionate Share and the monthly parking
privileges shall be reduced as of such date to an amount which shall reflect the deletion of the Recaptured Premises from the Premises, (4) Tenant and Landlord, upon request by either party, shall enter into an amendment to the Lease ratifying
and confirming such termination, and setting forth any appropriate modifications to the terms and provisions hereof, (5) Tenant will have no obligation to remove any alterations or leasehold improvements or Cabling in or serving the Recaptured
Premises or to restore such Recaptured Premises, and (6) subject to terms of this Article X, Landlord shall be free to lease the Recaptured Premises, or the portion thereof, to any person or persons. 

  
 38 

 B. Article X (Assignment and Subletting) of the Existing Lease (as amended by
Section 9(B)(ii) of the Third Amendment) is hereby amended to delete the second paragraph of Article X. Notwithstanding the provisions of Article X of the Existing Lease (as amended by Section 9(B)(ii) of the Third Amendment), Tenant shall
have the right to assign this Lease without the consent of Landlord but after reasonable advance notice (not less than [***] before the effective date of the assignment or subletting except that if prior notice to Landlord of such assignment,
sublease or transfer is prohibited by applicable securities laws or a written confidentiality agreement, then Tenant shall deliver such notice to Landlord within a reasonable time after Tenant is legally permitted to do so, but not later than the
date [***] after the occurrence of the proposed assignment, sublease or transfer in question) to any other entity (the “Successor Entity”) which (i) which controls or is controlled by Tenant, or (ii) which is under common
control with Tenant, or (iii) which purchases all or substantially all or substantially all of the assets or the business of Tenant, or (iv) which purchases a controlling interest in Tenant, or (v) which merges or combines with
Tenant, provided that any entity to which this Lease is so assigned h as a credit worthiness (e.g. net worth using generally accepted accounting principles consistently applied and using the most recent financial statements) which is the same or
better than the creditworthiness of the originally named Tenant as of the Fourth Amendment Execution Date (the foregoing transfers referred to, individually or collectively, as a “Permitted Transfers”). Tenant’s notice to
Landlord shall include information and documentation showing each of the above conditions have been satisfied. If requested by Landlord, Tenant’s successor shall sign a commercially reasonable form of assumption agreement. 

19. Security Deposit. 
 A. By not
later than [***] after the execution of this Fourth Amendment, Tenant shall deliver to Landlord a security deposit in the amount of [***] (the “Initial Security Deposit”), as security for the faithful performance and observance by
Tenant of the terms, covenants and conditions of the Lease. By not later than January 5, 2020, Tenant shall deliver to Landlord a security deposit in the amount of [***] (the “Additional Security Deposit”), as security for the
faithful performance and observance by Tenant of the terms, covenants and conditions of the Lease. The Initial Security Deposit plus the Additional Security Deposit, once delivered, in the amount of [***] in the aggregate, is referred to herein as
the “Security Deposit”. The Security Deposit shall be in the form of a clean, irrevocable, and unconditional letter of credit (the “Letter of Credit”) issued by and drawable upon a commercial bank which is
reasonably satisfactory to Landlord (the “Issuing Bank”), which has outstanding unsecured, uninsured and unguaranteed indebtedness, or shall have issued a letter of credit or other credit facility that constitutes the primary
security for any outstanding indebtedness (which is otherwise uninsured and unguaranteed), that is then rated, without regard to qualification of such rating by symbols such as “+” or “-” or numerical notation, “Aa” or
better by Moody’s Investors Service and “AA” or better by Standard & Poor’s Rating Service, and has combined capital, surplus and undivided profits of not less than [***]. Landlord hereby approved JPMorgan as the Issuing
Bank. The Letter of Credit shall (i) name Landlord as beneficiary, (ii) have a term of not less than one year, (iii) permit multiple drawings, (iv) either (x) be fully transferable by Landlord without the payment of any fees
or charges by Landlord, or (y) Tenant shall be obligated to cause a replacement Letter of Credit to be issued for the benefit of Landlord’s transferee, at no fee or charge to Landlord, subject only to the return of the original Letter of
Credit, and (v) otherwise be in a form reasonably acceptable to Landlord. If upon any transfer of the Letter of Credit, any fees or charges shall be so imposed, then such fees or charges shall be payable solely by Tenant, but only for the first
such transfer proposed by Landlord, and the Letter of Credit shall so specify. The Letter of Credit shall provide that it shall be deemed automatically renewed, without amendment, for consecutive periods of one year each thereafter during the Term
(and in no event shall the Letter of Credit expire prior to the thirtieth (30th) day following the Third Extended Termination Date): provided, however, the Issuing Bank may retain the right to send duplicate notices (the “Non-Renewal
Notices”) to Landlord and Tenant by certified mail, return receipt requested addressed to Landlord, not less than [***] next preceding the then expiration date of the Letter of Credit, stating that the Issuing Bank has elected not to renew
the Letter of Credit. The Issuing Bank shall agree with all drawers, endorsers and bona fide holders that drafts drawn under and in compliance with the terms of the Letter of Credit will be duly honored upon presentation to the Issuing Bank or its
correspondent bank at an office location in Boston, Massachusetts or by overnight delivery or facsimile in the continental United States. The Letter of Credit shall be subject in all respects to the International Standard Practice 1998 (ISP 98),
International Chamber of Commerce Practice, Publication No. 590. 

  
 39 

 B. If (i) an Event of Default of Tenant occurs under this Lease, or (ii) Landlord
receives a Non-Renewal Notice, or (iii) Tenant files a voluntary petition under any Federal or state bankruptcy or insolvency code, law or proceeding, then Landlord shall have the right by sight draft to draw, at its election, all or a portion
of the proceeds of the Letter of Credit and thereafter hold, use, apply, or retain the whole or any part of such proceeds, as the case may be, (x) to the extent required for the payment of any Rent or any other sum as to which Tenant is in
default including (1) any sum which Landlord may expend or may be required to expend by reason of Tenant’s default, and/or (2) any damages to which Landlord is entitled pursuant to the Lease, whether such damages accrue before or
after summary proceedings or other reentry by Landlord, and/or (y) as a cash security deposit, unless and until, in the case of clause (ii) above, Tenant delivers to Landlord a substitute Letter of Credit which meets the requirements of
this section. If Landlord applies or retains any part of the proceeds of the Letter of Credit, or cash security, Tenant, upon demand, shall amend the Letter of Credit to increase the amount thereof by the amount so applied or retained or provide
Landlord with an additional Letter of Credit in the amount so applied or retained so that Landlord shall have the full amount thereof on hand at all times during the Term. If Tenant shall comply with all of the terms, covenants and conditions of the
Lease, the Letter of Credit or cash security, as the case may be, shall be returned to Tenant not more than [***] after the Third Extended Termination Date and after delivery of possession of the Premises to Landlord in the manner required by this
Lease and the curing of any outstanding Event of Default of Tenant under this Lease. 
 C. The Letter of Credit shall also provide that
Landlord, its successors and assigns, may, at any time and without notice to Tenant and without first obtaining Tenant’s consent thereto, transfer (one or more times) all or any portion of its interest in and to the Letter of Credit to the
holder of any mortgage upon the Building or the successor landlord in connection with a transfer of the Building, from or as a part of the assignment by Landlord of its rights and interests in and to this Lease. In the event of a transfer of
Landlord’s interest in the Building, Landlord shall transfer the Letter of Credit, in whole or in part, to the transferee and thereupon Landlord shall without any further agreement between the parties, be released by Tenant from all liability
therefor. The provisions of this section shall apply to every transfer or assignment of the whole or any portion of said Letter of Credit to a new landlord. In connection with any such transfer of the Letter of Credit by Landlord, Tenant shall, at
Tenant’s sole cost and expense, execute and submit to the Issuing Bank such applications, documents and instruments as may be necessary to effectuate such transfer, and Tenant shall be responsible for paying the Bank’s transfer and
processing fees in connection therewith but only for the first such transfer proposed by Landlord. 

  
 40 

 D. If, as a result of any drawing by Landlord on the Letter of Credit, the amount of the
Letter of Credit shall be less than the Letter of Credit Amount, Tenant shall, within [***] thereafter, provide Landlord with additional letter(s) of credit or an amendment to the existing letter of credit in an amount equal to the deficiency, and
any such additional letter(s) of credit shall comply with all of the provisions of this Section and upon delivery, Landlord shall return to Tenant any cash security amount being held by Landlord. Tenant further agrees that it will neither assign nor
encumber the Letter of Credit or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance. 

E. Tenant hereby acknowledges and agrees that Landlord is entering into the Lease in material reliance upon the ability of Landlord to draw
upon the Letter of Credit upon the occurrence of any Event of Default on the part of Tenant under the Lease. If an Event of Default shall occur, Landlord may, but without obligation to do so, and without notice to Tenant, draw upon the Letter of
Credit, in part or in whole, to cure any Event of Default of Tenant and/or to compensate Landlord for any and all damages of any kind or nature sustained resulting from Tenant’s Event of Default. The use, application or retention of the Letter
of Credit, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by any applicable law, it being intended that Landlord shall not first be required to proceed against the
Letter of Credit, and shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled. Tenant agrees not to interfere in any way with payment to Landlord of the proceeds of the Letter of Credit, either prior to or
following a “draw” by Landlord of any portion of the Letter of Credit, regardless of whether any dispute exists between Tenant and Landlord as to Landlord’s right to draw upon the Letter of Credit. No condition or term of the Lease
shall be deemed to render the Letter of Credit conditional to justify the issuer of the Letter of Credit in failing to honor a drawing upon such Letter of Credit in a timely manner. Tenant agrees and acknowledges that (i) the Letter of Credit
constitutes a separate and independent contract between Landlord and the Issuing Bank, (ii) Tenant is not a third party beneficiary of such contract, (iii) Tenant has no property interest whatsoever in the Letter of Credit or the proceeds
thereof, and (iv) in the event Tenant becomes a debtor under any chapter of the Bankruptcy Code, neither Tenant, any trustee, nor Tenant’s bankruptcy estate shall have any right to restrict or limit Landlord’s claim and/or rights to
the Letter of Credit and/or the proceeds thereof by application of Section 502(b)(6) of the U. S. Bankruptcy Code or otherwise.

 F. Provided that as of the applicable Reduction Date, as set forth below, no default then
exists or has occurred in the immediately preceding twelve (12) month period (the “Reduction Conditions”), the amount of the Security Deposit shall be reduced as follows: 

 

					
	 Reduction Date
	  	Reduction Amount	 	Reduced Security
Deposit Amount
	 January 5, 2022
	  	[***]	 	[***]
	 January 5, 2023
	  	[***]	 	[***]
	 January 5, 2024
	  	[***]	 	[***]
	 January 5, 2025
	  	[***]	 	[***]
	 January 5, 2026
	  	[***]	 	[***]
	 January 5, 2027
	  	[***]	 	[***]

 The reduction in the Security Deposit shall be accomplished as follows: Tenant shall request such reduction in a written
notice to Landlord; and if the Reduction Conditions have been met, Landlord shall so notify Tenant within [***] thereafter, whereupon (i) Tenant shall provide Landlord with a substitute Letter of Credit in the Reduced Security Deposit Amount,
or an amendment to the Letter of Credit reducing it to the Reduced Security Deposit Amount, or (ii) Landlord shall return the positive excess of the cash then being held by Landlord as the Security Deposit, over the then-applicable Security
Deposit amount within [***]. If the Reduction Conditions are not satisfied on a particular Reduction Date because Landlord has identified in writing a default of Tenant under the Lease, and Tenant then cures the applicable default in
accordance with the terms and conditions of the Lease and twelve (12) months expires without any new default by Tenant under the Lease (or immediately if Tenant had not previously been notified of such default prior to the Reduction Date and
Tenant cures the same within the applicable notice and cure period under the Lease), then Tenant shall have the right to resubmit the request for and be entitled to the applicable reduction that was previously scheduled pursuant to the term and
conditions set forth above. The Security Deposit, as it may be reduced in accordance with the foregoing, shall continue to be held by Landlord throughout the Term. In no event shall the Security Deposit be less than [***].

of Tenant or Tenant’s agents, employees or contractors, Fixed Rent shall thereafter be abated in proportion to such untenantability until such the affected portion of the Premises is rendered tenantable to allow Tenant to occupy the affected
portion of the Premises. For the purposes hereof, the “Landlord Service Interruption Cure Period” shall be defined as [***] after Landlord’s receipt of written notice from Tenant of the condition causing untenantability in the
Premises; provided however, that the Landlord Service Interruption Cure Period shall be [***] after Landlord’s receipt of written notice from Tenant of such condition causing untenantability in the Premises if either the condition was caused by

[***] from the time that repair work would commence, as reasonably determined by Landlord’s Restoration Notice, and Landlord contemporaneously terminates the leases of all other occupants of the Office Area similarly affected by such fire or
casualty, then Landlord may, at its election, terminate this Lease by notice given to Tenant within [***] after the date of Landlord’s Restoration Notice, specifying the effective date of termination. The effective date of termination specified

C. If during the twenty-four (24) months of the Term (as it may have been extended), the Premises shall be damaged by fire or casualty and
such fire or casualty damage to the Premises cannot reasonably be expected to be repaired or restored within [***] from the time that repair or restoration work would commence as reasonably determined by Landlord in Landlord’s Restoration

one-year (as extended) period until the restoration is substantially completed, such termination to take effect as of the thirtieth (30th) day after the date of receipt by Landlord of Tenant’s notice, with the same force and effect as if
such date were the date originally established as the expiration date hereof unless, within such thirty (30) day period such restoration is substantially completed, in which case Tenant’s notice of termination shall be of no force and
effect and this Lease and the Lease Term shall continue in full force and effect. 
 G. Notwithstanding anything to the contrary contained in
this Lease and provided Landlord carried the insurance coverages required to be carried by Landlord under this Lease, if the Office Area or the Premises shall be substantially damaged by fire or casualty as the result of a risk not covered by the
forms of casualty insurance at the time required to be maintained by Landlord and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within [***] from the time that repair work would commence, Landlord

negligence or fault of any of the Tenant Parties.
