 2. Representations, Warranties, Covenants 

2.1 Representations and Warranties. The Borrower represents and warrants that: 

 

	 	(a)	This Mortgage has been duly executed and delivered by the Borrower and is the legal, valid and binding obligation of the Borrower enforceable in accordance with its terms, except as limited by bankruptcy, insolvency,
reorganization, moratorium and other laws affecting the enforcement of creditors’ rights generally; 

  
 2 

	 	(b)	The Borrower is the sole legal owner of the Property, holding good and marketable fee simple title to the Property, subject to no liens, encumbrances, leases, security interests or rights of others, other than as set
forth in Exhibit A attached hereto. 

  

	 	(c)	Each Obligation is a commercial obligation and does not represent a loan used for personal, family or household purposes and is not a consumer transaction or otherwise subject to the provisions of M.G.L. Chapter 140D,
the Federal Truth in Lending Act or Federal Reserve Board Regulation Z, or other such consumer statutes or regulations. 

 2.2
Recording Further Assurances. The Borrower covenants that it shall, at its sole cost and expense and upon the request of the Lender, cause the Mortgage, and each amendment, modification or supplement hereto, to be recorded and
filed in such manner and in such places, and shall at all times comply with all such statutes and regulations, as may be required by law in order to establish, preserve and protect the interest of the Lender in the Property and the rights of the
Lender under this Mortgage. Upon the written request of the Lender, and at the sole expense of the Borrower, the Borrower will promptly execute and deliver such further instruments and documents and take such further actions as the Lender may
deem desirable to obtain the full benefits of this Mortgage and of the rights and powers herein granted, including, without limitation, deliver of any certificate of title and filing any financing statement under the Uniform Commercial Code of
Massachusetts (M.G.L. c. 106). The Borrower authorizes the Lender to file any such financing statement without the signature of the Borrower, to the extent permitted by applicable law, and to file a copy of this Agreement in lieu of a financing
statement. 
 2.3 Restrictions on Sale by Borrower. The Borrower covenants that it will not, directly or indirectly, without the
prior written approval of the Lender, which approval shall not be unreasonably withheld, conditioned, or delayed, in each instance sell, convey, assign, transfer, mortgage, pledge, hypothecate, lease or dispose of all or any part of any legal or
beneficial interest in the Property or any part thereof or permit any of the foregoing, except as expressly permitted by the terms of the Security Instruments and except those transactions which are in the normal course of Borrower’s business,
or as permitted under the Loan Agreement. 
 2.4 Provisions Regarding the Leases. Except as permitted under the Loan
Agreement, Borrower shall not materially alter, modify or change any of the Leases or terminate the term thereof or accept a surrender thereof or cancel any of the Leases or waive or release any Lessee from the performance or observance by such
Lessee of any obligation or condition thereof, or execute an assignment of the Leases or the rents and profits there from, or agree, permit or consent to a subordination of any of the Leases to a mortgage or alter, amend or modify any guaranty of
said Leases or cancel or terminate such guaranty or consent to an assignment or subletting under any Lease or anticipate rents, or any other payments thereunder for more than thirty (30) days prior to accrual without the prior written consent of the
Lender, which consent shall not be unreasonably withheld, conditioned or delayed. 

  
 3 

 All subsequent Leases and tenancies for the use and occupation of the Property or any part
thereof shall be and are hereby made subject to all of the terms of the assignment referred to in Section 1.2 above, and the Borrower shall further assign and transfer the same to the Lender by assignment satisfactory to Lender upon their creation,
if Lender so requests. 
 Upon and during the continuation of an Event of Default, or any default in the covenants to be performed by
Borrower as lessor under any Lease, the Lender may, at its option, without notice, and without regard to the adequacy of the security for the indebtedness hereby secured, in person or by agent, with or without bringing any action, suit or
proceeding, enter upon and take possession of the Property, and have, hold, manage, lease and operate the same on such terms, employing such management agents and for such period of time as the Lender may deem proper; and may demand, collect and
receive all rents, issues and profits of the Property, and to do all things required of or permitted to the Lender as lessor under the Leases. It is not the intention of the parties hereto that an entry by the Lender upon the Property under the
terms of this instrument shall constitute the Lender a “mortgagee in possession” in contemplation of law, except at the option of the Lender. 

Notwithstanding the foregoing, so long as there is no Event of Default which has not been cured, the Borrower shall have the right to collect,
but not more than thirty (30) days prior to accrual, all rents, issues and profits from the Property and to retain, use and enjoy the same. 

Nothing herein shall obligate Lender to perform the obligations of Landlord under any of the Leases or other tenancy arrangements, which
obligations Borrower shall perform, and the Borrower hereby agrees to indemnify the Lender against and hold it harmless from any and all liability, loss or damage which it may or might incur under the Leases or under or by reason of the provisions
hereof and of and from any and all claims and demands whatsoever which may be asserted against it by reason of any alleged obligation or undertaking on its part to perform or discharge any of the terms of the Leases. Should the Lender incur any
such liability, loss or damage under any Lease or under or by reason of the provisions hereof, or in defense against any such claims or demands, the amount thereof, including costs, expenses and reasonable attorneys’ fees, together with
interest thereon at the rate set forth in the Note, shall be secured hereby and by the Mortgage, and the Borrower shall reimburse Lender therefor immediately upon demand and, upon failure to do so, the Lender may declare all sums evidenced by the
Note and secured hereby immediately due and payable.
 Lender shall have the right, by the execution of suitable written instruments, from
time to time, to subordinate this Mortgage and the right of Lender to any Lease from time to time in force with reference to the Property, and, on the execution of any such instrument, this Mortgage shall be subordinate to the Lease for which such
subordination is applicable with the same force and effect as if such Lease had been executed and delivered prior to the execution, delivery and recording of this Mortgage.

 2.5 Provisions Regarding Assigned Approvals. The Borrower covenants,
warrants and represents that it is and shall be the sole owner of the Assigned Approvals free and clear of all pledges, liens, security interests and other encumbrances of every nature whatsoever except those in favor of the Lender, has the full
right, power and authority to assign, and to grant the security interest in the Assigned Approvals as herein provided, shall not make any other assignment of, or permit any pledge, lien, security interest or other encumbrance to exist with respect
to, the Assigned Approvals except in favor of the Lender, and shall not transfer, assign, sell or exchange the Borrower’s interest in the Assigned Approvals. No Assigned Approvals shall be amended, modified or changed in any material
respect, or cancelled or terminated, without the Lender’s prior written consent in each instance. 
 So long as there is no Event of
Default, Borrower shall have and may exercise all rights as the owner or holder of the Assigned Approvals, which are lawful and are not inconsistent with the provisions of any of the Security Instruments. Immediately upon the occurrence of any
Event of Default, and for so long as the Event of Default remains uncured, the right described in the preceding sentence shall cease and terminate, and in such event the Lender is hereby expressly and irrevocably authorized (but not required) to
exercise every right, option, power or authority inuring to the Borrower under any one or more of the Assigned Approvals as fully as the Borrower could. In such event, the Borrower hereby irrevocably directs the grantor or licensor of, or the
contracting party to, any such Assigned Approval, to the extent permitted by such Assigned Approval and under any recognition or other agreement executed by such grantor, licensor or contracting party, upon demand and after notice from the Lender of
the Borrower’s default, to recognize and accept the Lender as the holder of such as such grantor, licensor or contracting party would recognize and accept the Borrower and its performance there under. 

Nothing contained herein shall operate to obligate or be construed to obligate the Lender to perform any of the terms, covenants or conditions
contained in the Assigned Approvals or otherwise to impose any obligation upon the Lender with respect to the Assigned Approvals prior to written notice by the Lender to the Borrower of the Lender’s election to assume the Borrower’s
obligations under one or more of the Assigned Approvals. Until such election, the payment, performance or observance of any obligation, requirement or condition under the Assigned Approvals is and shall be that of the Borrower. 

2.6 Provisions Regarding Plans and Specifications. The Borrower hereby agrees to obtain consents to the assignment of Plans and
Specifications provided for herein, and to obtain agreements to attorn directly to and recognize the Lender in place of the Borrower from and during the continuation of an Event of Default from construction contractor and from such other parties as
may be from time to time required by the Lender, such consents and agreements to be in form and substance reasonably satisfactory to the Lender. The Borrower hereby authorizes the Lender, at the Lender’s option, from and during the continuation
of an Event of Default to act as owner in place of the Borrower under such contracts and permits and directs all such other parties to such contracts and permits to recognize and perform for the Lender thereafter as if the Lender were the Borrower
hereunder and the Borrower hereby provides that such parties shall be fully protected from any liability to the Borrower in so doing.

 2.7 Insurance. With respect to the Property and any tangible personal property owned
by the Borrower comprising or intended to comprise any of the Collateral, Borrower shall obtain and maintain, and provide Lender with evidence of: (i) insurance coverages which meet all property, hazard and other insurance requirements of Lender
(including but not limited to physical hazard insurance on an “all risks” basis in an amount not less than 100% of the full replacement cost of the Property and flood insurance if and as required by applicable federal law and as otherwise
required by the Lender); and (ii) prepayment of the premiums for such insurance for at least one (1) year. 
 All policies regarding such
insurance shall be issued by companies licensed to do business in the state where the policy is issued and also in the Commonwealth of Massachusetts, be otherwise acceptable to the Lender, provide deductible amounts acceptable to the Lender, name
the Lender as mortgagee, loss payee and additional insured, and provide that no cancellation or material modification of such policies shall occur without at least thirty (30) days’ prior written notice to the Lender. Such policies shall
include: (i) a mortgage endorsement determined by the Lender in good faith to be equivalent to the “standard” mortgage endorsement so that the insurance, as to the interest of the Lender, shall not be invalidated by any act or neglect
of the Borrower or the owner of the Property, any foreclosure or other proceedings or notice of sale relating to the Property, any change in the title to or ownership of the Property, or the occupation or use of the Property for purposes more
hazardous than are permitted at the date of inception of such insurance policies; (ii) a replacement cost endorsement; (iii) an agreed amount endorsement; (iv) a contingent liability from operation endorsement; and (v) such other endorsements as the
Lender may request. The Borrower will furnish to the Lender upon request such original policies, certificates of insurance or other evidence of the foregoing as are acceptable to the Lender. The terms of all insurance policies shall be
such that no coinsurance provisions apply, or if a policy does contain a coinsurance provision, the Borrower shall insure the Property in an amount sufficient to prevent the application of the coinsurance provisions. 

In the event of a casualty, so long as no Event of Default has occurred and remains uncured, Lender shall release such portion of the
insurance proceeds as is necessary to restore the Property to its prior condition insofar as is practicable, so long as such insurance proceeds are sufficient to restore the Property and Borrower complies with Lender’s then standard
requirements with respect to the release of construction draws and so long as sufficient leases remain in place or Borrower has commitments for new leases such that sufficient revenues are generated to service the Note. 

2.8 Operation of Property. The Borrower covenants and agrees as follows: 

(a) unless Lender has otherwise consented in writing, not to allow changes in the nature of the occupancy or use for which the Property
was intended at the time this Mortgage was executed, shall not initiate or acquiesce in a change in the zoning classification of the Property, or subject the Property to restrictive or negative covenants; 

(b) not to permit the Property to be used for any unlawful or improper purpose, and at all times comply with all Federal, state and local
laws, ordinances and regulations, and to obtain and maintain all governmental or other approvals relating to the Borrower, the Property or the use 

  
 6 

 
thereof, including, without limitation, any applicable zoning or building codes or regulations and any laws or regulations relating to the handling, storage, release or cleanup of Hazardous
Substances, and to provide prompt written notice to the Lender of: (i) any violation of any such law, ordinance or regulation by the Borrower or relating to the Property; (ii) receipt of notice from any Federal, state or local authority
alleging any such violation; and (iii) the presence or release on the Property of any Hazardous Substances; 
 (c) at all times to keep
the Property in at least the same condition as it is as of the date hereof (damage from reasonable wear and tear, eminent domain taking, and damage by fire or other casualty excepted) and not to commit or permit any strip, waste, impairment,
deterioration or alteration of the Property or any part thereof; and 
 (d) to complete in a good and workmanlike manner, in accordance
with all applicable governmental laws, regulations and requirements, all improvements to be made to the Property.
 2.9 Inspection
Rights. The Borrower hereby grants to the Lender and its representatives, agents, contractors and employees the right to from time to time, upon reasonable notice to Borrower, to: (i) enter upon the Property and conduct such
inspections, testing, and studies of the Property as the Lender deems necessary or desirable; and (ii) examine all records and documents; including, without limitation, all test results or studies, reports, memoranda, licenses, permits and all other
papers or materials relating to the Property.
 2.10 Payment of Real Estate Taxes etc. The Borrower
shall pay when due all Federal, state, municipal or other taxes, betterment assessments and other governmental levies, water rates, sewer charges, insurance premiums and other charges on the Property, the Mortgage or any Obligation that could,
if unpaid, result in a lien on the Property or on any interest therein. Any time after the occurrence of an Event of Default, upon the demand of Lender, the Borrower shall deposit from time to time with the Lender sums determined by the Lender
to be sufficient to pay when due the amounts referred to in this paragraph. Notwithstanding the establishment of any such escrow account, the Borrower shall have the right to contest any notice, lien, encumbrance, claim, tax, charge, betterment
assessment or premium filed or asserted against or relating to the Property; provided that it contests the same diligently and in good faith and by proper proceedings and at the Lender’s request, provides the Lender with adequate cash security,
in the Lender’s reasonable judgment, against the enforcement thereof. The Borrower shall furnish to the Lender the receipted real estate tax bills or other evidence of payment of real estate taxes for the Property within five (5) days
prior to the date from which interest or penalty would accrue for nonpayment thereof. The Borrower shall also furnish to the Lender evidence of all other payments referred to above within fifteen (15) days after written request therefor by the
Lender. 
 2.11 Hazardous Waste. The Borrower warrants and represents that neither Borrower or any of the Borrower’s
agents or employees have, as of this date, caused, or are aware of a release or threat of release of any “oil”, “hazardous material”, “hazardous wastes” or “hazardous substances” (the “Materials”) as
those terms are defined under the Comprehensive Environmental Response, Compensation, and Liability Act, 42 U.S.C. Sec. 9601 et seq., as 

  
 7 

 
amended, the Massachusetts Hazardous Waste Management Act, M.G.L., Chapter 21C, as amended, and the Massachusetts Oil and Hazardous Material Release Prevention and Response Act, M.G.L., Chapter
21E, as amended, and regulations adopted there under (collectively the “Superfund and Hazardous Waste Laws”) on the Property; or arranged for the transport of, or transported any Materials in such a manner as to violate, or result in
potential liabilities under, any Superfund and Hazardous Waste Laws; or received any notification, order or demand from the Environmental Protection Agency or from the Commonwealth of Massachusetts (the “Commonwealth”) Department of
Environmental Quality Engineering under any of the Superfund and Hazardous Waste Laws; or incurred any liability under any Superfund and Hazardous Waste Laws in connection with the mismanagement, improper disposal, or release of any Materials; and,
to the best of the Borrower’s knowledge, no predecessor-in-title to the Property committed any act or omission which caused a release thereon which would give rise
to a lien on the Property filed with the Commonwealth of Massachusetts or the Federal government; and that no statement of claim or lien affecting the Property has been recorded or filed by the Federal government or the Commonwealth of Massachusetts
for costs incurred by such parties with respect to the Property or any other property owned by the undersigned; and that the Borrower is not aware of the presence of any Materials or the threat of a release of Materials on or in the Property which
could give rise to liability under any Superfund and Hazardous Waste Laws or under any other applicable Federal, state or local law, rule or regulation. Notwithstanding the foregoing, nothing shall prohibit Borrower or any occupant of the
Property from using any part thereof for the use, generation, treatment, storage or disposal of Hazardous Materials customarily used and in quantities customarily associated with the permitted use of the Property, so long as the same is in
compliance with all applicable laws and regulations. 
 2.12 Indemnification. The Borrower warrants and guaranties that all
certifications made in Section 2.11 above are true and correct to the best of the Borrower’s knowledge and belief. The Borrower hereby covenants and guaranties to protect, indemnify, and hold the Lender harmless from and against all loss,
damage, and expense, including attorney’s fees and costs of litigation, suffered or incurred by Lender under or on account of any circumstance subject to the Superfund and Hazardous Waste Laws, including, without limitation, all loss, damage
and expense incurred by the Lender on account of the filing of a lien against the Property by the Commonwealth of Massachusetts or the Federal government on account of the presence of any Materials located on or to be located on the
Property. The obligations of the Borrower hereunder shall not cease or lapse unless and until all obligations, under all documents executed in connection with the above-captioned loan, including payment
of indebtedness under the Note have been fully performed. 
 If in the event the Borrower shall receive notification of the presence of
hazardous waste on the Property from any agency of the Commonwealth of Massachusetts or of the Government of the United States of America, then the Borrower shall within three (3) days of its receipt thereof forward to the Lender at its principal
place of business a true and exact copy of the notice so received. Should the Borrower have reason to know that hazardous waste as defined in M.G.L. Chapter 21E, as amended, are present upon any or all of the Property, then the Borrower

  
 8 

 
shall immediately notify the Lender as recited above of the presence of the said hazardous waste. The failure of the Borrower to notify the Lender of notice of hazardous waste shall be
deemed to be a default by the Borrower and the Lender shall have the right to exercise its statutory powers relative to foreclosure and/or entrance upon the Property. 

In the event that there shall be a release of oil or hazardous materials or substances on, upon or into the Property, the Lender shall have
the right (but not the obligation), upon five (5) business days advance written notice to the Borrower (or without notice in the case of emergencies), to cause the release to be contained and/or removed on behalf of the Borrower. The
contractor(s) selected by the Lender shall have the right to enter upon the Property with such men, machinery and equipment as they shall deem necessary for such purpose and shall undertake such remedial containment and clean-up actions as they shall deem appropriate, without thereby incurring any liability to the Borrower on account thereof. The Borrower agrees to cooperate with any such contractor(s) and to render such
assistance to such contractor(s) as may be requested to facilitate the remedial containment and clean-up actions. The Borrower should be liable to the Lender for all costs and expenses, including all
attorneys fees incurred on account of such remedial action undertaken on the Borrower’s behalf and shall reimburse the Lender therefor on demand. In the event that the Borrower fails to so reimburse the Lender on demand, such failure shall
constitute an Event of Default hereunder. The Borrower hereby agrees to indemnify, defend and hold harmless the Lender from and against any and all loss, liability, damage and expense, including costs associated with the administrative and
judicial proceedings and attorney fees to which the Lender may become exposed, or which the Lender may incur, in exercising in whole or in part of failing or neglecting to exercise any of its rights under this section. 

2.13 Lender as Secured Party. In addition to the rights and remedies otherwise provided for by law or in equity and
in any of the Security Instruments, upon the occurrence and during the continuation of any Event of Default, (i) the Lender shall have the rights and remedies of a secured party under the Uniform Commercial Code, as enacted in Massachusetts (M.G.L.
c. 106), with respect to any of the Property owned by Borrower which constitutes personal property, subject to the applicable terms of the Loan Agreement; and (ii) the Borrower shall be deemed to have constituted and appointed the Lender its true
and lawful attorney-in-fact with full power of substitution in the Borrower’s name to do any act or to execute any document or instrument deemed by such attorney-in-fact to be necessary or desirable to be done or to be executed in order to
accomplish and effectuate any term of the collateral assignments set out here. It is understood and agreed that this power of attorney shall be deemed to be a power coupled with an interest which cannot be revoked. Notwithstanding the
foregoing, wherever Borrower appoints Lender as Borrower’s “true and lawful attorney”, such appointments shall only be effective five (5) days after Lender reasonably requests in writing that Borrower perform some act and Borrower
fails to do so or after an Event of Default which remains uncured. 

  
 9 

 3. Certain Rights of the Lender 

3.1 Legal Proceedings. The Lender shall have the right, but not the duty, to intervene or otherwise participate in any legal
or equitable proceeding that, in the Lender’s reasonable judgment, might affect the Property or any of the rights created or secured by this Mortgage. The Lender shall have such right whether or not there shall have occurred an Event of
Default. 
 3.2 Appraisals/Assessments. The Lender shall have the right, at the Borrower’s sole cost and expense, to
obtain appraisals, environmental site assessments or other inspections of the portions of the Property that are real estate at such times as the Lender deems necessary or as may be required by applicable law, or prevailing Lender credit or
underwriting policies. Notwithstanding the foregoing, so long as no Event of Default has occurred and remains uncured and any governmental regulatory agency does not require additional appraisals, Lender shall order no more than one appraisal
at Borrower’s expense during the term of the Note, and in the absence of the occurrence of a release of Materials giving rise to Lender’s reasonable belief of contamination of the Property, Lender shall not order any environmental site
assessments at Borrower’s expense. 
 4. Defaults and Remedies 

4.1 Events of Default. Event of Default shall mean the occurrence of any one or more of the Events of Default set forth in
the Note or any of the Security Instruments. 
 4.2    Remedies. On the occurrence and during the
continuation of any Event of Default the Lender may, at any time thereafter, at its option and, to the extent permitted by applicable law, without notice, exercise any or all of the remedies set forth in the Note or any of the Security Instruments,
as applicable. 
 4.3 Cumulative Rights and Remedies. All of the foregoing rights, remedies and options are cumulative and
in addition to any rights the Lender might otherwise have, whether at law or by agreement and may be exercised separately or concurrently. The Borrower further agrees that the Lender may exercise any or all of its rights or remedies set forth
herein without having to pay the Borrower any sums for use or occupancy of the Property. 
 4.4 Borrower’s Waiver of Certain
Rights. To the extent permitted by applicable law, the Borrower hereby waives the benefit of all present and future laws (i) providing for any appraisal before sale of all or any portion of the Property, or (ii) in any way
extending the time for the enforcement of the collection of the Obligations or creating or extending a period of redemption from any sale made hereunder. 

5. Miscellaneous 
 5.1
Waiver of Homestead. The Borrower hereby waives and terminates any rights to any homestead exemptions on record as of the date of this Mortgage respecting the Property under the provisions of M.G.L. c. 188, § 1. 

  
 10 

 5.2 Severability. If any provision of this Mortgage or portion of such provision
or the application thereof to any person or circumstance shall to any extent be held invalid or unenforceable, the remainder of this Mortgage (or the remainder of such provision) and the application thereof to other persons or circumstances shall
not be affected thereby. 
 5.3 Exercise of Rights. Borrower agrees that all rights of the holder hereof as to personal
property security and real estate security may be exercised together or separately and further agrees that, in exercising its power of sale, such holder may sell the personal property security or any part thereof either separately from, or together
with, the real estate security or any part thereof, in such order as such holder may, in its discretion, elect, and whether or not the aggregate proceeds thereof exceed the indebtedness secured by this Mortgage. At any sale, any combination of
or all of the security may be offered for sale for one total price and the proceeds of such sale accounted for in one account without distinguishing between the items of security or assigning to the separate securities proportions of the proceeds of
such sale accounted for in one account without distinguishing proportions of the proceeds; and, in case such holder, in the exercise of the power of sale herein given, elects to sell in parts or parcels, said sales may be held from time to time and
the power shall not be fully executed until all of the personal property security and real estate security not previously sold shall have been sold. 

5.4 Condominium Provisions. If, and to the extent that any of the Property includes a unit in a condominium project
(the “Condominium Project”) the Property shall include Borrower’s undivided interest in the common elements of the Condominium Project, the title to which is held by a unit owner’s association (the “Owners’
Association”) and the uses, proceeds and benefits of Borrower’s interest therein. In such case, and in addition to the covenants and agreements made elsewhere in this Mortgage, Borrower further covenant and agree as follows: 

 

	 	A.	Borrower shall perform all of Borrower’s obligations under the Condominium Project’s Constituent Documents. The “Constituent Documents” are the (i) Master Deed or any other document which
creates the Condominium Project; (ii) declaration of trust, by-laws, and regulations (or other equivalent documents) of or by the Owners’ Association”) Borrower shall promptly pay, when due, all dues and assessments imposed pursuant to the
Constituent Documents. 

  

	 	B.	Borrower shall take such actions as may be reasonable to insure that the Owners’ Association maintains, with a generally accepted insurance carrier, a “master” or “blanket” policy which is
satisfactory to the Lender and which provides hazard insurance coverage in the amounts, for the periods, and against the hazards the Lender requires, including fire hazards included within the term “extended coverage”, and Borrower shall
give the Lender prompt notice of any lapse in such required hazard insurance coverage. In the event of a distribution of hazard insurance proceeds in lieu of restoration or repair following a loss to the Property, whether to the unit or to
common elements, any proceeds payable to Borrower are hereby assigned and shall be paid to the Lender for application to the Obligations, with any excess paid to Borrower. 

  
 11 

	 	C.	Borrower shall take such actions as may be reasonable to insure that the Owners’ Association maintains a public liability insurance policy acceptable in form, amount, and extent of coverage to the Lender.

  

	 	D.	The proceeds of any award or claim for damages, direct or consequential, payable to Borrower in connection with any condemnation or other taking of all or any part of the Property, whether of the unit or of the common
elements, or for any conveyance in lieu of condemnation, are hereby assigned and shall be paid to the Lender. Such proceeds shall be applied by the Lender to the sums secured by the Mortgage as provided for in paragraph 2.7 of the Mortgage.

  

	 	E.	Borrower shall not, except after notice to the Lender and with the Lender’s prior written consent, either partition or subdivide the Property or consent to:

condemnation or eminent domain; 

  

	 	(ii)	any amendment to any provision of the Constituent Documents if the provision is not for the express benefit of the Lender; 

  

	 	(iii)	termination of professional management and assumption of self-management of the Owners Association; or

Mortgage. Unless Borrower and the Lender agree to other terms of payment, these amounts shall bear interest from the date of disbursement at the Note rate and shall be payable, with interest, upon notice from the Lender to Borrower requesting
payment

acknowledges that the acceptance by the Lender of any payments from either the Borrower or the Guarantor after the occurrence and during the continuation of any Event of Default, the exercise by the Lender of any remedy set forth herein or the
commencement of foreclosure proceedings against the Property shall not waive the Lender’s right to foreclose or operate as a bar or estoppel to the exercise of any other rights or remedies of the Lender. The Borrower agrees and
acknowledges that the Lender, by making payments or incurring costs described herein, shall be subrogated to any right of the Borrower to seek reimbursement from any third parties, including, without limitation, any predecessor in interest to the

LAWS AND MAY NOT BE TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER SUCH ACT AND ALL SUCH STATE SECURITIES LAWS OR AN EXEMPTION FROM REGISTRATION IS AVAILABLE.” 

The Company covenants and agrees that, upon request, it will remove the Legend from any such shares upon the earlier to occur of: (i) in the case of
Common Shares, once such shares are registered under the Securities Act; or (ii) in the case of Common Shares or Preferred Shares covered by a Legend, promptly following the Company’s receipt of an opinion of counsel satisfactory to the

proposed transfer and, if requested by the Company, shall be accompanied by an opinion of counsel satisfactory to the Company (it being agreed that Baker Botts L.L.P. or Choate, Hall & Stewart LLP shall be satisfactory for this purpose) to
the effect that the proposed transfer may be effected without registration under the Securities Act and any applicable state securities laws, whereupon such Holder shall be entitled to transfer such stock in accordance with the terms of its notice;
provided, however, that no such opinion of counsel shall be required for a transfer by the Investor to an Affiliate of the Investor. Notwithstanding the foregoing and subject to the restrictions contained in Section 22, Preferred
Shares or Common Shares owned by a Holder may not be transferred to a Competitor (as such term is defined in the Second Amended and Restated Investor Rights Agreement, by and among the Company, SeaChange, LGIV and Summit, dated on or around the date
hereof, as amended and/or restated from time to time). Each certificate for Preferred Shares or Common Shares transferred as above provided shall bear the Legend, except that such certificate shall not bear the Legend if (i) such transfer is in
accordance with the provisions of Rule 144 (or any other rule permitting public sale without registration under the Securities Act) or (ii) the opinion of counsel referred to above is to the further effect that the transferee and any
subsequent transferee would be entitled to transfer such securities in a public sale without registration under the Securities Act. The restrictions provided for in this Section 3 shall not apply to securities which are not required to bear the
Legend prescribed by Section 2 in accordance with the provisions of that Section. 

  
 -5- 

 4. Required Registration.

(a) At any time after the earliest of (i) six months after the Company’s initial registration statement covering a public offering
of securities of the Company under the Securities Act shall have become effective and (ii) six months after the Company shall have initially become a reporting company under Section 12 of the Exchange Act, a Holder with a demand
registration right (as set forth in Section 4(c)) may, by written notice to the Company (a “Demand Request”), request the Company to prepare and file a registration statement registering all or a portion of the Registrable
Shares owned by such Holder under the Securities Act on an appropriate form under the Securities Act (a “Demand Registration Statement”), in each case, for the type of offering contemplated by the Demand Request (which may include
an offering to be made on a delayed or continuous basis under Rule 415, if the Company is then permitted to rely upon such Rule), provided that the Registrable Shares for which registration has been requested shall constitute at least
20% of the total Registrable Shares held by such Holder issued and outstanding as of the date hereof if such Holder shall request the registration of less than all Registrable Shares owned by such Holder (or any lesser percentage if the reasonably
anticipated aggregate price to the public of such public offering would exceed $5,000,000). For purposes of this Section 4 and Sections 5, 6, 15 and 18, solely for purposes of determining a percentage of Registrable Shares then
outstanding, as of any date of determination, there shall be deemed outstanding the Warrant Shares and all Common Shares into which any Preferred Shares or other securities owned by a Holder are then exercisable or then convertible, as the case may
be; provided, however, that the only securities which the Company shall be required to register pursuant hereto shall be shares of Common Stock; and provided, further, however, that, in any underwritten public
offering contemplated by this Section 4 or Sections 5 and 6, the Holders shall be entitled to (i) in the case of Preferred Shares, to sell such shares to the underwriters for conversion into shares of Common Stock which are then sold
in the offering or (ii) in the case of Preferred Shares and the Warrant, make the conversion or exercise thereof, as the case may be, contingent upon the Registration Statement for the offering being declared effective and the underwriting
agreement being signed by the underwriters. Notwithstanding anything to the contrary contained herein, no request may be made under this Section 4 within 120 days after the effective date of a Registration Statement filed by the
Company solely for the account of the Company covering a firm commitment underwritten public offering in which the Holders shall have been entitled to join pursuant to Section 5 or Section 6 and in which there shall have been registered
all Registrable Shares as to which registration shall have been requested. 
 (b) Following receipt of any Demand Request under this
Section 4, the Company shall immediately notify (each such notice, a “Demanded Registration Notice”) all Holders of Registrable Shares (if any) from whom the applicable Demand Request was not received and shall use its best
efforts to register under the Securities Act, for public sale in accordance with the method of disposition specified in such Demanded Registration Notice, the number of Registrable Shares specified in such Demanded Registration Notice (and in all
notices received by the Company from other Holders within 30 days after the date of the Demanded Registration Notice). If such method of disposition shall be an underwritten public offering, Holders of a majority of the Registrable Shares
to be sold in such offering may designate the managing underwriter of such offering, subject to the approval of the Company, which approval shall not be unreasonably withheld or delayed.

  
 -6- 

 (c) The Company shall be obligated to register Registrable Shares pursuant to this Section 4
on only two occasions where the Demand Request is initiated by Summit, two occasions where the Demand Request is initiated by SeaChange and two occasions where the Demand Request is initiated by LGIV, provided, however, that such
obligation shall be deemed satisfied when a Registration Statement covering all Registrable Shares specified in a Demand Request (and all notices in response to a Demanded Registration Notice) received by the Company shall have become effective and,
(A) if such method of disposition is a firm commitment underwritten public offering, all such shares shall have been sold pursuant thereto or (B) if such method of disposition is not a firm commitment underwritten public offering, such
Registration Statement has remained effective for a period of not less than 120 days (such 120-day period to be tolled during any period in which the prospectus included in a Registration Statement may not be used under the circumstances
described in Section 7(a)(vi) or Section 17(c)) or, if shorter, until such time as all shares covered thereby have been sold pursuant thereto. 

(d) The Company shall be entitled to include for sale in any Demand Registration Statement, whether for its own account or for the account of
Other Stockholders, in accordance with the method of disposition specified in the applicable Demand Request, shares of Common Stock. If such method of disposition shall be an underwritten offering and the managing underwriter(s) advises the
Company in writing that the number of Registrable Shares and Other Shares proposed to be registered exceeds the Maximum Number of Shares, then the following “cutback” rules shall apply: there will be included in such registration
(x) first, (I) if the applicable Demand Request was made by Summit or LGIV in accordance with the provisions hereof, the shares requested to be included by the Holders, which shares shall be allocated, if the aggregate number of such
shares exceeds the Maximum Number of Shares, pro rata among all Holders on the basis of the number of shares each Holder had originally requested to include in such registration, (II) if the applicable Demand Request was made by SeaChange in
accordance with the provisions hereof and the aggregate number of shares requested to be included by SeaChange and Summit exceeds the Maximum Number of Shares, the shares requested to be included by SeaChange and Summit, which shares shall be
allocated pro rata among SeaChange and Summit on the basis of the number of shares each such Holder had originally requested to include in such registration, and (III) if the applicable Demand Request was made by SeaChange in accordance with
the provisions hereof and the aggregate number of shares requested to be included by SeaChange and Summit does not exceed the Maximum Number of Shares, the shares requested to be included by SeaChange and Summit, and then the shares requested to be
included by LGIV to the extent that such shares of LGIV may be included in such registration without the amount of registered securities thereunder exceeding the Maximum Number of Shares, (y) second, to the extent that any additional shares of
Common Stock may be included in such registration without the amount of registered securities thereunder exceeding the Maximum Number of Shares, the shares of Common Stock that the Company proposes to issue for its own account, the number of which
shares may not exceed the difference between the Maximum Number of Shares and those shares proposed to be included pursuant to clause (x); and (z) third, to the extent that any additional shares of Common Stock may be included in such
registration without the amount of registered securities thereunder exceeding the Maximum Number of Shares, the shares of Common Stock that the Company proposes to issue for the account of any Other Stockholder pro rata among such Persons on the
basis of the number of shares such Persons had originally requested to include in such registration. If a Demand Registration 

  
 -7- 

 
Statement involves an underwritten offering of Registrable Shares, then the Company and/or any Other Stockholders whose shares are included in such Demand Registration Statement shall sell their
shares in the underwritten offering on the same terms and conditions as those applicable to the Registrable Shares. Except for registration statements on Form S-4,
S-8 or any successor thereto, the Company will not file with the Commission any other registration statement with respect to its Common Stock, whether for its own account or that of Other Stockholders, from
the date of receipt of a Demand Request until the completion of the period of distribution of the registration contemplated thereby.
 (e)
Notwithstanding anything to the contrary contained herein, at any time prior to the effective time of a Demand Registration Statement, the Holder that submitted the Demand Request in respect of such registration statement may request withdrawal of,
and the Company shall withdraw, such Demand Registration Statement. Any withdrawn Demand Registration Statement shall count towards one of the demand registrations of such Holder referred to in the first sentence of Section 4(c), unless the
Holder(s) reimburse the Company for its reasonable out-of-pocket expenses incurred in connection with the preparation and filing of such withdrawn Demand Registration Statement (insofar as such expenses relate to the registration of Registrable
Shares). 
 (f) The right of any Holder to initiate a Demand Request shall automatically terminate if such Holder no longer owns any
Registrable Shares. 
 5. Incidental Registration.

(a) If the Company at any time (other than pursuant to Section 4 or Section 6) proposes to register any of its securities under the
Securities Act for sale to the public, whether for its own account or for the account of other security holders or both (except with respect to registration statements on Forms S-4, S-8 or another form not available for registering the offer and sale of restricted shares to the public), each such time the Company will give written notice to all Holders of Registrable Shares of its intention so
to do. Upon the written request of any such Holder, received by the Company within 30 days after the giving of any such notice by the Company, to register any of such Holder’s Registrable Shares, the Company will use its best efforts,
subject to Section 5(b), to cause all the Registrable Shares as to which registration shall have been so requested to be included among the securities to be covered by the Registration Statement proposed to be filed by the Company, all to the
extent requisite to permit the sale or other disposition by the Holder of such Registrable Shares so registered.
 (b) In the event that any
registration pursuant to this Section 5 shall involve an underwritten public offering of Common Stock and the number of shares proposed to be included therein exceeds the Maximum Number of Shares, then the following “cutback” rules
shall apply: 
 (i) If the registration was originated by the Company for a primary offering, then there will be included in such
registration: (x) first, all of the shares of Common Stock that the Company proposes to issue for its own account; and (y) second, to the extent that any additional shares of Common Stock may be included in such registration without the
amount of registered securities thereunder exceeding the Maximum Number of Shares, the shares 

  
 -8- 

 
proposed to be included by all Holders, if any, which shares shall be allocated, if the aggregate number of shares proposed to be included by clause (x) and this clause (y) exceeds the
Maximum Number of Shares, pro rata among such Persons on the basis of the number of shares such Persons had originally requested to include in such registration; and (z) third, to the extent that any additional shares of Common Stock may
be included in such registration without the amount of registered securities thereunder exceeding the Maximum Number of Shares, the shares proposed to be included by the Other Stockholders, if any, allocated pro rata among such Persons on the
basis of the number of shares such Persons had originally requested to include in such registration; 
 (ii) If the registration was
originated by a Holder, then there will be included in such registration: (x) first, all of the shares of Common Stock that each Holder proposes to register, which shares shall be allocated, if the aggregate number of shares exceeds the Maximum
Number of Shares, in accordance with clause (x) of the second sentence of Section 4(d) above; (y) second, to the extent that any additional shares of Common Stock may be included in such registration without the amount of registered
securities thereunder exceeding the Maximum Number of Shares, those shares of Common Stock proposed to be registered by the Company; and (z) if such number of shares described in the foregoing clauses (x) and (y) do not exceed the Maximum
Number of Shares, the shares proposed to be included by Other Stockholders, if any, allocated pro rata among such Persons on the basis of the number of shares such Persons had requested to include in such registration; and 

(iii) If the registration was originated by Other Stockholders, then there will be included in such registration: (x) first, all of the
shares of Common Stock that such originating Other Stockholders, the Company and the Holders propose to register, which shares shall be allocated, if the aggregate number of shares proposed to be included by this clause (x) exceeds the Maximum
Number of Shares, pro rata among such Persons on the basis of the number of shares such Persons had requested in include in such registration; and (y) if such number of shares described in the foregoing clause (x) does not exceed
the Maximum Number of Shares, the shares proposed to be included by any Other Stockholders that are not included among such originating Other Stockholders, if any, allocated pro rata among such Persons on the basis of the number of shares
such Persons had requested to include in such registration. 
 (c) Notwithstanding anything to the contrary contained herein, at any time
prior to the effective time of a registration pursuant to this Section 5, (i) the Company may withdraw such registration without incurring any liability to any Holder and (ii) a Holder may withdraw the Registrable Shares that it had
sought to have included therein without incurring any liability to the Company. 
 6. Registration on
Form S-3. If at any time (i) one or more Holders request in a written notice that the Company file a registration statement on Form S-3 (or any
successor thereto) for a public offering of all or any portion of the Registrable Shares held by such requesting Holder(s), the reasonably anticipated aggregate price to the public of which would exceed $5,000,000, and (ii) the Company is a
registrant entitled to use Form S-3 (or any successor thereto) to register the offer and sale of such shares in accordance with the intended manner of disposition thereof, then the Company shall use its
best efforts to promptly register under the Securities Act on a registration on Form S-3 (or any successor thereto), for public sale 

  
 -9- 

 
in accordance with the method of disposition specified in such notice, the number of Registrable Shares specified in such notice. Whenever the Company is required by this Section 6 to use
its best efforts to effect the registration of Registrable Shares, each of the procedures and requirements of Section 4 (including but not limited to (i) the requirement that the Company notify all other Holders of Registrable Shares from
whom notice has not been received and provide them with the opportunity to participate in the offering, (ii) the provisions regarding allocations in Section 4(d) and (iii) the last sentence of Section 4(a)) shall apply to such
registration, provided, however, that the Company shall not be required to effect more than two registrations in any twelve-month period under this Section 6, and provided, further, however, that the
requirements contained in the first sentence of Section 4(a) shall not apply to any registration on Form S-3 which may be requested and obtained under this Section 6.

7. Registration Procedures.

(a) If and whenever the Company is required by the provisions of Sections 4, 5 or 6 to effect registration of the offer and sale of any
Registrable Shares pursuant to a Registration Statement to be filed under the Securities Act, the Company will: 
 (i) at least three
business days prior to the initial filing of the Registration Statement with the Commission, furnish to Special Counsel a copy of such Registration Statement as proposed to be filed, and the Company will in good faith consider incorporating into
such Registration Statement any comments of Special Counsel received by the Company within three business days of furnishing such copy. If a Registration Statement is reviewed by the Commission: (A) the Company will as promptly as reasonably
practicable provide Special Counsel with a copy of each comment letter issued in respect of such Registration Statement and a copy of the Company’s proposed responses thereto; (B) the Company shall further provide Special Counsel with a
copy of any proposed amendment to be filed with the Commission no less than four business days prior to the Company’s proposed filing date; (C) the Company will in good faith consider incorporating into such amendment any comments of
Special Counsel received by the Company within three business days of furnishing such copy; and (D) once the Registration Statement is cleared from review, the Company will as promptly inform Special Counsel of the effectiveness thereof. The
Company will use its best efforts to cause a Registration Statement to become effective as promptly as practicable after the initial filing thereof with the Commission and use its best efforts to cause such Registration Statement to remain effective
for the period of the distribution contemplated thereby (determined as hereinafter provided). 
 (ii) after a Registration Statement is
initially declared effective, prepare and file with the Commission such amendments and supplements to such Registration Statement and the related prospectus as may be necessary to keep such Registration Statement effective for the period of the
distribution contemplated thereby and comply with the provisions of the Securities Act with respect to the disposition of all Registrable Shares covered by such Registration Statement in accordance with the sellers’ intended method of
disposition set forth in such Registration Statement for such period. The Company shall, at least three business days prior to the filing of a post-effective amendment to the Registration Statement or a prospectus (including a prospectus supplement,
a Free Writing Prospectus and any documents to be incorporated by reference in the prospectus to the extent they expressly relate to an offering 

  
 -10- 

 
under the Registration Statement), furnish a copy of such proposed filing to Special Counsel and any underwriter (if such filing relates to an underwritten offering), and the Company will in good
faith consider incorporating into such proposed filing any comments of Special Counsel received by the Company within two business days of furnishing such copy. 

(iii) as promptly as reasonably practicable furnish to Special Counsel copies of any and all transmittal letters and other correspondence
with the Commission and all correspondence from the Commission to the Company relating to the Registration Statement or any prospectus or any amendment or supplement thereto. 

(iv) after a Registration Statement is declared effective, and in connection with any underwritten offering under the Registration Statement,
furnish to the Holders whose Registrable Shares are included in such Registration Statement such number of copies of the Registration Statement, each amendment and supplement thereto (in each case including all exhibits thereto but excluding
documents incorporated by reference therein other than those that expressly relate to the offering), the prospectus included in such Registration Statement (including any prospectus supplements) and such other documents as any such Holders or
underwriters may reasonably request in order to facilitate the disposition of the Registrable Shares included in the Registration Statement. 

(v) use its best efforts (i) to register or qualify the Registrable Shares under such other securities or blue sky laws of such
jurisdictions in the United States (in the event an exemption is not available) as any Holder of Registrable Shares covered by a Registration Statement reasonably (in the light of such Holder’s intended plan of distribution) requests and
(ii) to do any and all other acts and things that may be reasonably necessary or advisable to enable such Holder to consummate the disposition in such jurisdictions of the Registrable Shares owned by such Holder; provided that the
Company will not be required to (w) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 7(a)(v), (x) conform its capitalization or the composition of its assets at
the time to the securities or blue sky laws of any such jurisdiction, (y) subject itself to taxation in any such jurisdiction or (z) consent to general service of process in any such jurisdiction. 

(vi) as promptly as reasonably practicable notify each other Holder of Registrable Shares covered by the Registration Statement, at any time
when a prospectus relating thereto is required to be delivered (or deemed delivered) under the Securities Act, of the occurrence of an event of which the Company has knowledge requiring the preparation of a supplement or amendment to such prospectus
so that, as thereafter delivered (or deemed delivered) to the purchasers of such Registrable Shares, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under which they are made, not misleading, and the Company will as promptly as reasonably practicable prepare and furnish to such Holders a supplement to or an amendment of such
prospectus so that, as thereafter delivered (or deemed delivered) to the purchasers of such Registrable Shares, such prospectus will not contain any untrue statement of material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading. 

  
 -11- 

 (vii) enter into reasonable and customary agreements (including an underwriting or other
agreement in form customary in the securities business for companies of the size and investment stature of the Company) and use best efforts to take such other actions as are reasonably required or requested by a Holder or underwriter in order to
expedite or facilitate the disposition of any Registrable Shares pursuant to a Registration Statement. 
 (viii) upon execution of a
customary confidentiality agreement (if such Holder is not already bound by a confidentiality obligation to the Company), make available for inspection by any Holder of Registrable Shares covered by a Registration Statement, any underwriter
participating in an underwritten offering pursuant to the Registration Statement, Special Counsel, and any attorney, accountant or other professional retained by any such Holder or underwriter (collectively, the “Inspectors”), all
financial and other records, pertinent corporate documents and properties of the Company (collectively, the “Records”) and cause the Company’s and its significant subsidiaries’ officers, directors and employees to, and
shall use commercially reasonable efforts to cause the Company’s independent accountants to, as promptly as reasonably practicable, supply all information reasonably requested by any Inspector in connection with such Registration Statement or
underwritten offering, in each case, to the extent reasonably necessary to establish the applicable Person’s due diligence defense under U.S. securities laws; provided that in no event shall the Company be required to make available to
the Holders any information which the Board of Directors in its good faith judgment believes is competitively sensitive. The Inspectors shall coordinate with one another so that the inspection permitted hereunder will not unnecessarily interfere
with the Company’s conduct of business. In any event, Records which the Company determines, in good faith, to be confidential and which it notifies or otherwise identifies in writing to the Inspectors are confidential shall not be disclosed by
the Inspectors unless (and only to the extent that) (i) the disclosure of such Records is necessary to permit a Holder to enforce its rights under this Agreement or (ii) the release of such Records is ordered pursuant to a subpoena or
other order from a court of competent jurisdiction. Each Holder agrees that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the
securities of the Company (unless and until such is made generally available to the public by the Company) or for any reason not related to the registration of Registrable Securities. Each Holder further agrees that it will, upon learning that
disclosure of such Records is sought in a court of competent jurisdiction, cause give notice to the Company and allow the Company, at its expense, to undertake appropriate action to prevent disclosure of the Records deemed confidential. 

(ix) otherwise use best efforts (i) to comply with all applicable rules and regulations of the Commission to the extent necessary to
permit it to lawfully fulfill its obligations under this Agreement, and (ii) to make available to its security holders, as promptly as reasonably practicable, an earnings statement covering a period of 12 months, beginning upon the first
disposition of Registrable Shares pursuant to a Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act. 

(x) use its best efforts to cause all Registrable Shares to be listed on each securities exchange on which the Common Stock is then listed.

  
 -12- 

 (b) For purposes of Section 7(a)(i) and 7(a)(ii), the period of distribution of Registrable
Shares in a firm commitment underwritten public offering shall be deemed to extend until each underwriter has completed the distribution of all securities purchased by it, and the period of distribution of Registrable Shares in any other
registration shall be deemed to extend until the earlier of the sale of all Registrable Shares covered thereby and 120 days after the effective date thereof (such 120-day period to be tolled during any period in which the prospectus included in
a Registration Statement may not be used under the circumstances described in Section 7(a)(vi) or 17(c)). 
 (c) In connection with
each Registration Statement filed hereunder covering Registrable Shares, the Holders of such shares will furnish to the Company in writing such information with respect to themselves and the proposed distribution by them as reasonably shall be
necessary in order to assure compliance with federal and applicable state securities laws. 
 8. Expenses. The Company will pay all
Registration Expenses incurred in connection with the performance of its obligations pursuant to Sections 4, 5 or 6. All Selling Expenses in connection with the offer and sale of Registrable Shares shall be borne by the selling Holders in
proportion to the number of Registrable Shares sold by each, or in such other proportion as they may mutually agree among themselves. 
 9.
Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless to the fullest extent permitted by law each Holder whose Registrable Shares are covered by a Registration Statement, its officers, directors and each
Person, if any, who controls such Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities, and expenses, or any action or proceeding
in respect thereof (each, a “Liability” and collectively, “Liabilities”) (including reimbursement of such Holder for any legal or any other expenses reasonably incurred by it in investigating or defending such
Liabilities) arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in such Registration Statement or any prospectus relating to such Registrable Shares (or in any amendment or supplement thereto),
or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any violation of any securities law by the
Company or any officer or employee of the Company, except insofar as such Liabilities arise out of or are based upon any such untrue statement or omission or alleged untrue statement or omission based upon information furnished in writing to the
Company by such Holder expressly for use therein or except insofar as such Liabilities arise out of any violation of any securities law by such Holder resulting from any action or omission of such Holder in connection with such Registration
Statement. 
 (b) Each Holder whose Registrable Shares are included in a Registration Statement agrees, severally and not jointly, to
indemnify and hold harmless to the fullest extent permitted by law the Company, its officers, directors, agents, and each Person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20
of the Exchange Act, to the same extent as the foregoing indemnity from the Company to such Holder in Section 9(a) (including reimbursement of the Company for any legal or any other expenses reasonably incurred by it in investigating or
defending such Liabilities), but only to the extent such Liabilities arise out of or are based upon information furnished in writing by such Holder expressly for use in the Registration Statement, prospectus or in any amendment or

  
 -13- 

 
supplement thereto relating to such Holder’s Registrable Shares or to the extent such Liabilities arise out of any violation of any securities law by such Holder resulting from any action or
omission of such Holder in connection with such Registration Statement; provided, however, that the liability of such Holder hereunder shall be limited to the proportion of any such Liabilities which is equal to the proportion that the
public offering price of the Registrable Shares sold by such Holder under such Registration Statement bears to the total public offering price of all securities sold thereunder, but not in any event to exceed the net proceeds received by such Holder
from the sale of its Registrable Shares covered by such Registration Statement. 
 (c) After receipt by any Person (an “Indemnified
Party”) of any notice of the commencement of any action, suit, proceeding or investigation or threat thereof in respect of which indemnity may be sought pursuant to Section 9(a) or 9(b), such Indemnified Party shall as promptly as
reasonably practicable notify the Person against whom such indemnity may be sought (the “Indemnifying Party”) in writing. Following notice of commencement of any such action given to the Indemnifying Party as above provided,
the Indemnifying Party shall be entitled to participate in and, to the extent it may wish, jointly with any other Indemnifying Party similarly notified, to assume the defense of such action at its own expense, with counsel reasonably satisfactory to
such Indemnified Party. In any such proceeding so assumed by the Indemnifying Party, any Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified
Party unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (ii) representation of both parties by the same counsel would be inappropriate due to actual or potential
differing or conflicting interests between them. It is understood that the Indemnifying Party, in connection with any proceeding or related proceedings in the same jurisdiction, shall be liable only for the reasonable fees and expenses of one firm
of attorneys (in addition to any necessary local counsel) at any time for all such Indemnified Parties, and that all such fees and expenses shall be reimbursed as they are incurred upon submission of reasonably itemized invoices. In the case of
any such separate firm for Holders who are entitled to indemnity pursuant to Section 9(a), such firm shall be designated in writing by the Indemnified Party who had the largest number of Registrable Shares included in the Registration Statement
at issue. The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, but if settled with such consent, or if there be a final judgment for
the plaintiff, the Indemnifying Party shall indemnify and hold harmless such Indemnified Parties from and against any loss or liability (to the extent set forth in this Section 9) by reason of such settlement or judgment. No Indemnifying
Party shall, without the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld, conditioned or delayed, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified
Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such proceeding. 

(d) If the indemnification provided for hereunder shall for any reason be held by a court of competent jurisdiction to be unavailable to an
Indemnified Party in respect of any Liability referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such
Liabilities between the Company on the one hand and each Holder whose 

  
 -14- 

 
Registrable Shares are covered by the Registration Statement in issue on the other, in such proportion as is appropriate to reflect the relative fault of the Company and of each such Holder in
connection with any untrue statement of a material fact contained in the Registration Statement, any prospectus or any amendment or supplement thereto or caused by any omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, which resulted in such Liabilities, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and of each such Holder on the other shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such party, and the parties’
relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 
 (e) The Company and
the Holders (including each Permitted Transferee) agree that it would not be just and equitable if contribution pursuant to Section 9(d) were determined by pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in Section 9(d). The amount paid or payable by an Indemnified Party as a result of the Liabilities referred to in Section 9(d) shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, no Holder shall be required to
contribute any amount in excess of the amount of the net proceeds received by such Holder from the sale of its Registrable Shares covered by the Registration Statement in issue. No Person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Exchange Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 

10. Recapitalization, Exchanges, etc. The provisions of this Agreement shall (i) apply to the full extent set forth herein
with respect to any and all securities into which any of the Registrable Shares are converted, exchanged or substituted in any recapitalization or other capital reorganization involving the Company and (ii) be appropriately adjusted for any
dividends of Common Stock in respect of the Common Stock, stock splits, reverse splits, combinations, recapitalizations and the like occurring after the date hereof.

11. Rule 144 Reporting. In order to make available to the Holders the benefits of certain rules and regulations of the
Commission which may permit the sale of Registrable Shares to the public without registration under the Securities Act, at all times after ninety (90) days after the effective date of any Registration Statement covering a public offering of
securities of the Company under the Securities Act, the Company agrees to: 
 (a) make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act; 
 (b) use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and 

  
 -15- 

 (c) furnish to each Holder forthwith upon request a written statement by the Company as to its
compliance with the reporting requirements of the Securities Act and the Exchange Act, and the rules and regulations thereunder, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by
the Company as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any Registrable Shares without registration. 

12. Binding Effect. This Agreement shall be binding upon and inure to the benefit of the Company and the Holders and their respective
successors and Permitted Transferees. 
 13. Notices. All notices, requests, consents and other communications hereunder shall be in
writing and shall be delivered in person, mailed by certified or registered mail, return receipt requested, or sent by telecopier or telex, addressed to such party at the address of such party set forth on the signature page hereto, or, in any case,
at such other address or addresses as shall have been furnished in writing to the Company (in the case of a Holder) or to the Holders (in the case of the Company). In the case of any notice sent to Summit, a copy of such notice (which shall not be
deemed notice) shall be sent to Choate, Hall & Stewart LLP, Two International Place, Boston, MA 02110, Attention T.J. Murphy, Fax: (617) 248-4000, Email: tmurphy@choate.com. 

14. Governing Law. This Agreement shall be construed and enforced in accordance with and governed by the laws of the State of
Massachusetts, without regard to its principles of conflicts of laws. 
 15. Amendments and Waivers. Any amendment, modification or
supplement of or to, or any waiver of, any term or condition of this Agreement shall be effective only if in writing and signed by the Company and Holders owning a majority of the Registrable Shares then outstanding. Notwithstanding the
foregoing, this Agreement may not be amended, modified or supplemented, and the observance of any term hereunder may not be waived, with respect to a Holder without the written consent of such Holder unless such amendment, modification, termination
or waiver applies to all Holders in the same fashion and, in connection therewith, no Holder receives any consideration or other inducement that is not received by all Holders. No failure to enforce any provision of this Agreement shall be deemed to
or shall constitute a waiver of such provision and no waiver of any of the provisions of this Agreement shall be deemed to or shall constitute a waiver of any other provision hereof (whether or not similar) nor shall such waiver constitute a
continuing waiver. 
 16. Counterparts. This Agreement may be executed in any number of counterparts, all of which taken
together shall constitute one and the same instrument, and any Party may execute this Agreement by signing any such counterpart.
 17.
Termination; Suspension. 
 (a) The obligations of the Company to register Registrable Shares under Sections 4, 5 or 6 shall
terminate on the earlier to occur of (i) no Registrable Shares being outstanding and (ii) the seventh anniversary of the initial public offering of the Company’s Common Stock. 

  
 -16- 

 (b) If requested in writing by the underwriters for the initial underwritten public offering of
securities of the Company, no Holder shall sell publicly any Registrable Shares or any other shares of Common Stock (other than Registrable Shares or other shares of Common Stock being registered in such offering), without the consent of such
underwriters, for a period of not more than one hundred and eighty (180) days following the effective date of the registration statement relating to such offering (plus up to an additional 34 days to the extent requested by the managing
underwriters for such offering in order to address NASD Rule 2711(f) of the Financial Industry Regulatory Authority, Inc. or any similar successor provision); provided, however, that all other Persons selling shares of Common
Stock in such offering, all holders of at least 1% of the Company’s outstanding shares of Common Stock (assuming for such purpose the conversion of all outstanding equity securities into Common Stock) and all officers and directors of the
Company shall also have agreed not to sell publicly their Common Stock under the circumstances and pursuant to the terms set forth in this Section 17(b). 

(c) Notwithstanding the provisions of Section 7(a), the Company’s obligation to file a Registration Statement, or cause such
Registration Statement to become and remain effective, may be suspended, for the shortest period practicable and in any event for a period not to exceed ninety (90) days in any 24-month period (a “Blackout Period”), if the Company
determines, in good faith, that to file such Registration Statement, or for it to remain effective, would (i) require the public disclosure of material non-public information concerning any transaction or negotiations involving the Company or
any of its consolidated subsidiaries that would materially interfere with such transaction or negotiations, (ii) require the public disclosure of material non-public information concerning the Company at a time when its directors and executive
officers are restricted from trading in the Common Stock or (iii) otherwise materially interfere with financing plans, acquisition activities or business activities of the Company. If the Company declares a Blackout Period with respect to a
Demand Registration Statement that has not yet been declared effective, then the Holder(s) that submitted the Demand Request in respect of such registration statement may request withdrawal of, and the Company shall withdraw, such Demand
Registration Statement (i) without it counting towards one of the demand registrations referred to in the first sentence of Section 4(c) and (ii) without the Holders having any liability to the Company in respect of any expenses it
incurred in connection with the preparation and filing of such withdrawn Demand Registration Statement. 
 18. Future Registration
Rights. After the date hereof and for so long as this Agreement remains in effect, without the prior written consent of the holders of a majority of the Registrable Shares, the Company shall not grant to any Person the right to (a) require
the Company to initiate the registration of any securities, or (b) require the Company to include in any registration securities owned by such Person, unless under the terms of such arrangement such Person may include securities in such
registration only to the extent that the inclusion thereof does not limit the number of Registrable Shares included therein or adversely affect the offering price thereof (as determined by the managing underwriter(s) for such offering).

19. Severability. The provisions of this Agreement are severable and, in the event that any court of competent jurisdiction shall
determine that any one or more of the provisions or part of a provision contained in this Agreement shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not
affect any other provision or part of a provision of this Agreement; but this Agreement shall be reformed and construed as if such invalid or illegal or unenforceable provision, or part of a provision, had never been contained herein, and such
provisions or part reformed so that it would be valid, legal and enforceable to the maximum extent possible. 

  
 -17- 

 20. Further Assurances. From and after the date of this Agreement, upon the request of any
other Party, each Party shall execute and deliver such instruments, documents and other writings as may be reasonably necessary or desirable to confirm and carry out and to effectuate fully the intent and purposes of this Agreement. 

21. Specific Enforcement. Each Party acknowledges and agrees that the other Parties would be irreparably damaged if any of the
provisions of this Agreement are not performed in accordance with their specific terms and that any breach of this Agreement by the Parties could not be adequately compensated in all cases by monetary damages alone. Accordingly, in addition to any
other right or remedy to which any Party may be entitled under this Agreement, at law or in equity, it shall be entitled to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent
injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement, without posting any bond or other undertaking.

22. Transfer of Registration Rights. Each Holder shall have the right to transfer, by written agreement, any or all of its rights
granted under this Agreement to any direct or indirect transferee of such Holder’s Registrable Shares (each Person to whom such Registrable Shares shall have been so transferred hereunder, a “Permitted Transferee”);
provided, (i) such transferee is an Affiliate of the Investor or (ii) such transferee is transferred at least 100,000 Registrable Shares (subject to appropriate adjustment for stock splits, stock dividends, recapitalizations and
similar events occurring after the date of this Agreement), and in either such case, (x) such transferee agrees, in writing in form and substance reasonably satisfactory to the Company, to be bound by the terms and provisions of this Agreement;
and (y) such transfer of Registrable Shares shall be effected in accordance with applicable securities laws, this Agreement and any other agreements relating to the Registrable Shares between the Company and such Holder. A Permitted Transferee
shall have all of the rights of a Holder hereunder as to any Registrable Shares owned by it. Following any transfer or assignment made pursuant to this Section 22 in connection with the transfer by a Holder of a portion of its Registrable
Shares, such Holder shall retain all rights under this Agreement with respect to the remaining portion of its Registrable Shares.
