 ARTICLE 2 
 PREMISES AND APPURTENANT RIGHTS 
 2.1 Lease of
Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the Premises for the Term and upon the terms and conditions hereinafter set forth. Effective as of January 1, 2004, this Lease fully and completely
amends, restates, and supercedes the Existing Leases in all respects. 
 2.2 Appurtenant Rights and Reservations.

 (a) Tenant shall have, as appurtenant to the Premises, the non-exclusive right to use, and permit its invitees
to use in common with Landlord and others, (i) public or common lobbies, hallways, stairways, elevators and common walkways necessary for access to the Buildings and the Premises, and if the portion of the Premises on any floor includes less
than the entire floor, the common toilets, corridors and elevator lobby of such floor; and (ii) the access roads, driveways, loading areas, pedestrian sidewalks, trash enclosures and other areas or facilities, if any, which are located in or on
the Property and designated by Landlord from time to time for the non-exclusive use of tenants and other occupants of the Buildings (the “Common Facilities”); but such rights shall always be subject to reasonable rules and
regulations from time to time established by Landlord pursuant to Section 15.8 (the “Rules and Regulations”) and to the right of Landlord to designate and change from time to time areas and facilities so to be used.

 (b) Excepted and excluded from the Premises and the Common Facilities are the ceiling, floor, perimeter walls
and exterior windows (except the inner surface of each thereof), and any space in the Premises used for shafts, stacks, pipes, conduits, fan rooms, ducts, electric or other utilities, sinks or other Building facilities, but the entry doors (and
related glass and finish work) to the Premises are a part thereof. Landlord shall have the right to place in, over and through the Premises (but in such manner as to reduce to a minimum interference with Tenant’s use of the Premises) interior
storm windows, sun control devices, utility lines, equipment, stacks, pipes, conduits, ducts and the like. In the event that Tenant shall install any hung ceilings or walls in the Premises, Tenant shall install and maintain, as Landlord may require,
proper access panels therein to afford access to any facilities above the ceiling or within or behind the walls. Tenant shall be entitled to install any such ceilings or walls only in compliance with the other terms and conditions of this Lease.

 (c) Landlord shall cause Tenant’s name, and the names of Tenant’s departments,
affiliates, and senior officers, to be listed on the building directories in the lobbies of the respective Buildings. In addition, tenant identification signage for Tenant has previously been installed in the elevator lobbies of the respective
floors on which the Premises are located and in the respective entry areas of the Premises. Landlord and Tenant both acknowledge and agree that all such existing identification signage is satisfactory and acceptable. Landlord shall provide building
standard tenant identification signage for Tenant in the elevator lobby of the 3rd Floor of the Ten P.O. Square Building and in the lobby areas on the respective floors on which additional areas may be added to the Premises pursuant to Article 17 or Article 23.

  

 -10- 

 (d) Tenant may elect, at Tenant’s sole cost and expense, to construct
and erect a sign identifying Tenant as an occupant of the Building on the exterior of the Ten P.O. Square Building, which sign (including, without limitation, the size, location, design, materials, colors and appearance thereof) shall be subject to
the prior review and approval of Landlord in all respects. Tenant shall, at its sole cost and expense, prepare all plans and specifications relating to such exterior sign, obtain all required permits and approvals from governmental authorities
required in connection with such sign, and be responsible for all costs and expenses of constructing, maintaining, repairing and replacing said sign. Landlord shall have no obligations or liabilities with respect to such sign, including, without
limitation, relating to the obtaining of required permits or approvals with respect thereto, or the construction, installation, maintenance, repair, or replacement thereof, all of which shall be at the sole risk, cost and expense, of Tenant.
Landlord shall maintain and repair such sign and, within not more than thirty (30) days after receipt of invoices therefor, Tenant shall reimburse Landlord for all such costs and expenses, as Additional Rent. In the event that Tenant is unable
to obtain required approvals and permits from governmental authorities in connection with the proposed sign, then neither party shall have any further rights, claims, obligations, or liabilities with respect thereto. 
 (e) At the request of Tenant and at Tenant’s sole cost and expense, Landlord will install a canopy with 3 sides of
illuminated signage displaying the name of “Boston Private Bank & Trust Company” at the existing Milk Street entrance to the Ten P.O. Square Building, which canopy (including, without limitation, the size, location, design,
materials, colors, signage, illumination, and appearance thereof) shall be subject to the prior review and approval of Landlord in all respects. Tenant shall, at its sole cost and expense, prepare all plans and specifications relating to such
canopy, obtain all required permits and approvals from governmental authorities required in connection with such canopy, and be responsible for all costs and expenses of constructing, maintaining, repairing and replacing said canopy. Landlord shall
have no obligations or liabilities with respect to such canopy, including, without limitation, relating to the obtaining of required permits or approvals with respect thereto, all of which shall be at the sole risk, cost and expense, of Tenant.
Landlord shall maintain and repair such canopy and, within not more than thirty (30) days after receipt of invoices therefor, Tenant shall reimburse Landlord for all such costs and expenses, as Additional Rent. In the event that Tenant is
unable to obtain required approvals and permits from governmental authorities in connection with the proposed canopy, then neither party shall have any further rights, claims, obligations, or liabilities with respect thereto. 
 (f) Pursuant to the Existing Sublease, Tenant has subleased the Subleased Premises. The term of the Existing Sublease expires
on January 31, 2005 and prior to the expiration or earlier termination of the Existing Sublease the Subleased Premises shall not be considered to be part of the Premises for purposes of this Lease. Without limitation, neither Landlord nor
Tenant shall have any obligations or liabilities

  

 -11- 

 
under this Lease with respect to the Subleased Premises unless and until the expiration or earlier termination of the Existing Sublease. Concurrent with the expiration or earlier termination of
the Existing Sublease, the Subleased Premises automatically shall become part of the Premises for all purposes under this Lease, in accordance with and subject to the terms and conditions hereof. In no event will the Existing Sublease be extended,
amended or otherwise modified except with the prior written consent of Landlord in each instance. 
 ARTICLE 3 

BASIC RENT 
 3.1 Payment. 
 (a) Tenant agrees to pay the Basic Rent and Additional Rent to Landlord,
or as directed by Landlord, commencing on the Commencement Date, without offset, abatement (except as expressly and specifically provided in Section 11.4), deduction or demand. Basic Rent shall be payable in equal monthly installments,
in advance, on the first day of each and every calendar month during the Term of this Lease, to Landlord at Landlord’s Address or at such other place as Landlord shall from time to time designate by notice, in lawful money of the United States.
In addition to any charges under Section 14.4, in the event that during any twelve (12) consecutive months two (2) or more installments of Basic Rent or any regularly scheduled payment of Additional Rent are not paid when due,
then Tenant shall pay, at Landlord’s request an administrative fee equal to three percent (3%) of each such overdue payment. Landlord and Tenant agree that all amounts due from Tenant under or in respect of this Lease, whether labeled
Basic Rent, Escalation Charges, Additional Rent or otherwise, shall be considered as rental reserved under this Lease for all purposes, including, without limitation, regulations promulgated pursuant to the Bankruptcy Code, and including further
without limitation Section 502(b) thereof. 
 (b) Basic Rent for any partial month shall be pro-rated on a
daily basis, and if the first day on which Tenant must pay Basic Rent shall be other than the first day of a calendar month, the first payment which Tenant shall make to Landlord shall be equal to a proportionate part of the monthly installment of
Basic Rent for the partial month from the first day on which Tenant must pay Basic Rent to the last day of the month in which such day occurs, plus the installment of Basic Rent for the succeeding calendar month. 
 (c) Landlord has agreed to provide a rent credit to Tenant on account of a portion of the rent payable by Tenant under the
Existing sublease. Accordingly, without limiting the obligations of Tenant to pay Basic Rent and Additional Rent hereunder, provided that (i) no uncured Event of Default then exists under this Lease, and (ii) the Existing Sublease remains
in full force and effect through January 31, 2005, Tenant shall be entitled to a rent credit of $100,000.00, which credit may be applied in 13 equal monthly installments of $7,692.31 each against the monthly payments of Basic Rent which are
payable on the first day of each month commencing on January, 2004 and continuing through January, 2005. 
  

 -12- 

 (d) Pursuant to the Existing Leases, Tenant has previously made payments on
account of basic rent, real estate taxes and operating expenses to Landlord for the period of time between January 1, 2004 and the date of this Lease. Landlord has agreed to provide a rent credit to Tenant to the extent such payments on account
of basic rent, real estate taxes and operating expenses actually paid by Tenant under the Existing Leases exceed the Basic Rent and Escalation Charges payable under this Lease for such period of time. Accordingly, without limiting the obligations of
Tenant to pay Basic Rent and Additional Rent hereunder, provided that no Event of Default then exists under this Lease, Tenant shall be entitled to a rent credit of $535,377.95, which credit may be applied in 3 equal monthly installments of
$178,459.31 each against the monthly payments of Basic Rent which are payable on each of July 1, 2004, August 1, 2004, and September 1, 2004.

greater than Landlord’s Initial Contribution. Provided that this Lease is in full force and effect and no Default of Tenant then exists, such progress payments shall be made within thirty (30) days after the delivery to Landlord of
requisitions therefor, signed by a duly authorized officer of Tenant, setting forth the names of each contractor, subcontractor, payee, and supplier to whom payment has been made by Tenant, and the amount thereof, and accompanied by

sums so due from Tenant, and Tenant agrees the same shall be deemed Additional Rent and shall be paid by Tenant within ten (10) days after Landlord delivers to Tenant an invoice therefor, or, at Landlord’s election, be deducted from the

authorized officer of Tenant and, with respect to payments on account of Alterations, as also certified by Tenant’s independent architect) to Tenant’s contractors, subcontractors, and material suppliers that have not been subject to
previous disbursements from Landlord’s Additional Contribution. In no event shall Landlord pay in the aggregate an amount greater than Landlord’s Additional Contribution. Provided that this Lease is in full force and effect and no Event of
Default then exists, such progress payments shall be made within thirty (30) days after the delivery to Landlord of requisitions therefor, signed by a duly authorized officer of Tenant, setting forth the names of each contractor, subcontractor,
payee, and supplier to whom payment has been made by Tenant, and the amount thereof, and accompanied by (i) evidence of payment by Tenant of the amounts sought to be reimbursed (such as paid receipts); (ii) with respect to payments on

required by this provision, Landlord shall have the right, but not the obligation, to promptly pay to such contractor or supplier all sums so due from Tenant, and Tenant agrees the same shall be deemed Additional Rent and shall be paid by Tenant
within ten (10) days after Landlord delivers to Tenant an invoice therefor, or, at Landlord’s election, be deducted from the unpaid balance of Landlord’s Additional Contribution. 
 (f) Landlord shall pay the final installment of the Landlord’s Additional Contribution to Tenant within thirty

(iii) with respect to payments on account of Alterations, proof of the satisfactory completion of all required inspections and the issuance of any required approvals and sign-offs by Governmental Authorities with respect thereto, (iv) if
requested by Landlord, final “as-built” plans and specifications for the subject Alterations, and (v) such other documents and information as Landlord may reasonably request in connection therewith.

Boston Private Financial Holdings, Inc. is (or are) in occupancy of not less than sixty-five (65%) of the rentable area of the Premises then demised under this Lease,

  

 -16- 

 
then Tenant may extend the Term of this Lease for three (3) successive periods (each, an “Extension Period”) of five (5) years each by written notice (each, a
“Tenant’s Extension Notice”) to Landlord given at least sixteen and one-half (16.5) months prior to the commencement of each such Extension Period. Delivery of each Tenant’s Extension Notice shall unconditionally constitute
the exercise by Tenant of the option to extend the Term of this Lease and in no event may Tenant revoke a Tenant’s Extension Notice, then such notice shall be irrevocable after delivery thereto. Immediately after delivery of each Tenant’s
Extension Notice this Lease shall be automatically extended in accordance with the provisions of this Section 4.4. Each such extension shall be for and with respect to the entirety of the Premises then demised under this Lease. Each such
extension shall be on the same terms and conditions set forth herein, except that (a) after the exercise of the third (3rd) such extension option Tenant shall have no further option to extend said Term, (b) Basic Rent payable with
respect to each such Extension Period shall be equal to 97.5% of the fair market rental value of the Premises during said Extension Period, as determined by Landlord promptly after receipt of Tenant’s Extension Notice (subject to Tenant’s
right to object thereto as hereinafter set forth), and (c) Landlord shall have no obligation to make or pay for any improvements to the Premises or to pay any allowances or inducements of any kind. In determining fair market rental value, the
following factors, among others, shall be taken into account and given effect: size of the premises, escalation charges then payable under the lease, location of the premises, location of the building, tenant improvement and fit-up of the premises,
other transaction costs and lease term, and other terms and conditions then being provided for comparable lease transactions in comparable office buildings in the Downtown Boston Financial District. 
 (b) Promptly after receipt of a Tenant’s Extension Notice, Landlord shall deliver to Tenant a notice
(“Landlord’s Determination Notice”) setting forth Landlord’s determination of the fair market rental value of the Premises with respect to such Extension Period. In the event that Tenant objects to Landlord’s determination
of fair market rental value with respect to such Extension Period, Tenant may elect, by giving Landlord written notice of such objection not later than fifteen (15) Business Days following receipt of the Landlord’s Determination Notice, to
deliver to Landlord a notice (a “Tenant’s Appraisal Notice”) that Tenant elects to submit the determination of fair market rental value to appraisers, the first appraiser to be chosen by Landlord, the second appraiser to be chosen by
Tenant, and a third appraiser to be selected by the two appraisers first chosen. If Tenant fails to deliver to Landlord a Tenant’s Appraisal Notice within such fifteen (15) Business Day period (time being of the essence thereof), then
Tenant shall have no further right to object to Landlord’s determination of fair market rental value for such Extension Period, and Tenant conclusively shall be deemed to have accepted Landlord’s determination of the fair market rental
value of the Premises for such Extension Period. 
 (c) If Tenant timely delivers a Tenant’s Appraisal
Notice pursuant to subsection (b) above, then the unanimous written decision of the two appraisers first chosen, without selection and participation of a third appraiser, or otherwise the written decision of a majority of three appraisers
chosen and selected as aforesaid, shall be conclusive and binding upon Landlord and Tenant. Landlord and Tenant shall each notify the other of its chosen appraiser within ten (10) days following receipt by Landlord

  

 -17- 

 
of Tenant’s Appraisal Notice. If within thirty (30) days after the second appraiser has been appointed, the two designated appraisers are unable to agree upon fair market rental value
for the Extension Period, then within ten (10) days after expiration of such thirty (30) day period they shall elect a third appraiser who has the qualifications set forth in subsection (d) below. If the two appraisers are not able to
agree upon such third appraiser within such ten (10) day period, either appraiser may request the office of the American Arbitration Association located within or nearest to Boston, Massachusetts to designate a third appraiser willing so to act
and an appraiser so appointed shall, for all purposes, have the same standing and powers as though he had been seasonably appointed by the appraisers first appointed. In the case of the inability or refusal to serve of any person designated as an
appraiser, or in case any appraiser for any reason ceases to be such, an appraiser, to fill such vacancy, having the minimum qualifications set forth in subsection (d) below, shall be promptly appointed by the Landlord, the Tenant, the
appraiser first appointed by the Landlord, the appraiser first appointed by the Tenant, or the said office of the American Arbitration Association, as the case may be, whichever made the original appointment, or, if the person who made the original
appointment fails to fill such vacancy, any appraiser who continues to act, or the Landlord, or the Tenant may apply to said office of the American Arbitration Association to fill such vacancy with an appraiser having the minimum qualifications set
forth in subsection (d) below, and any appraiser so appointed to fill such vacancy shall have the same standing and powers as though originally appointed. The resulting board of appraisers shall, forthwith upon their appointment, (i) hear
the parties to this Lease and their witnesses, (ii) examine the records relating to the Premises, market surveys and such other documents and records as may, in their judgment, be necessary, and (iii) within not more than forty-five
(45) days after their appointment, issue a decision (the “Appraisers’ Decision”) determining the fair market rental value of the Premises for such Extension Period. 
 Any determination by a majority of the members of the board of appraisers shall be final and binding upon the parties, but if
a majority of the members of the board of appraisers are unable to agree upon a determination, the determination of such third appraiser shall be binding upon the parties. If any party shall fail to appear at the hearings appointed by the
appraisers, the appraisers may act in the absence of such party. The determination of the board of appraisers (or the third appraiser, as appropriate) made in accordance with the foregoing provisions may be entered as an award in arbitration in a
court of competent jurisdiction, and judgment thereon may be entered. 
 (d) Landlord and Tenant shall each bear
the expense of the appraiser chosen by it and shall equally bear the expense of the third appraiser (if any). All appraisers chosen or elected hereunder shall have received the M.A.I. (Member Appraisal Institute) designation from the American
Institute of Real Estate Appraisers and shall have had at least ten (10) years of experience in appraising commercial office space and determining fair market rental values in office buildings in Downtown Boston comparable to the Building. If,
as contemplated herein, the Basic Rent payable with respect to said Extension Period shall not have been determined prior to the commencement thereof, then said Extension Period shall nevertheless commence, and Tenant shall make payments of Basic
Rent at 97.5% of the fair market rental value

  

 -18- 

 
designated by Landlord, subject to retroactive adjustment in conformity with and within ten (10) days following the final determination of the fair market rental value by the appraisers.

 (e) Time is of the Essence of this Section 4.4. 
 ARTICLE 5 
 USE OF PREMISES 
 5.1 Permitted Use. 
 (a) Tenant agrees that the Premises shall be used and occupied by Tenant only for the Permitted Uses and for no other purpose or purposes, including, without limitation, use for medical, dental,
governmental, utility company or employment agency offices, without Landlord’s express prior written consent. Tenant shall not use, or suffer or permit the use of, or suffer or permit anything to be done in or anything to be brought into or
kept in or about the Premises or the Buildings or any part thereof (i) which would violate any of the provisions of this Lease, (ii) for any unlawful purposes or in any unlawful manner, (iii) which is not customarily found in
first-class office buildings in the downtown Boston area, or (iv) which, in the reasonable judgment of Landlord, shall in any way (A) impair the appearance or reputation of either of the Buildings, or (B) impair or interfere with any
of the Building services or the proper and economic heating, ventilation, cleaning, air conditioning or other servicing of either of the Buildings or Premises, or with the use of any of the other areas of either of the Buildings, or occasion
discomfort, inconvenience or annoyance to, any of the other tenants or occupants of either of the Buildings. 
 (b) Tenant agrees to conform to the following provisions during the Term of this Lease: 
 (i) Tenant
shall cause all freight to be delivered to or removed from either of the Buildings and the Premises from the Kilby Street entrance, in accordance with the Rules and Regulations established from time to time by Landlord therefor; 
 (ii) Tenant will not place on the exterior of the Premises (including both interior and exterior surfaces of doors and
interior surfaces of windows) or on any part of the Buildings outside the Premises, any sign, symbol, advertisement or the like visible to public view outside of the Premises. Landlord will not withhold consent for signs or lettering on the entry
doors to the Premises provided such signs conform to sign standards adopted from time to time by Landlord in its sole discretion and Tenant has submitted to Landlord a plan or sketch in reasonable detail (showing, without limitation, size, color,
location, materials and method of affixation) of the sign to be placed on such entry doors. Landlord agrees, to maintain a tenant directory in the lobby of each respective Building (and, in the case of multi-tenant floors, in that floor’s
elevator lobby) in which will be placed Tenant’s name and the location of the Premises in the respective Building; 
  

 -19- 

 (iii) Tenant shall not perform any act or carry on any practice which may
injure the Premises, or any other part of either Building, or cause any offensive odors or loud noise or constitute a nuisance or a menace to any other tenant or tenants or other persons in either Building; 
 (iv) Tenant shall, in its use of the Premises, comply with the requirements of all applicable governmental laws, rules and
regulations, including, without limitation, the Americans With Disabilities Act of 1990 and the codes, rules and regulations promulgated thereunder (collectively, the “ADA”) and the codes, rules and regulations of the Massachusetts
Architectural Access Board (collectively, the “MAAB Regulations”); provided however, Landlord shall be responsible for the compliance of the common areas of the Buildings with the ADA and the MAAB Regulations; and 
 (v) Tenant shall not abandon the Premises. 
 5.2 Installations and Alterations by Tenant. 
 (a)
Tenant shall make no alterations, additions (including, for the purposes hereof, wall-to-wall carpeting), or improvements (collectively, “Alterations”) in or to the Premises (including any Alterations necessary for Tenant’s
initial occupancy of the Premises) without Landlord’s prior written consent, which consent shall not be unreasonably withheld or delayed with respect to non-structural Alterations that do not affect or involve the Building’s electrical,
plumbing or mechanical systems or any other Building systems; provided, however, no such consent shall be required with respect to non-structural Alterations that do not affect or involve the structural elements of the respective Building, or the
electrical, plumbing or mechanical systems of the respective Building, or any other Building systems, having an aggregate cost to completion of less than $25,000.00 for each such Alteration project. Landlord’s failure to approve or reject plans
and specifications for a proposed Alteration within fifteen (15) Business Days of receipt of same shall be deemed an approval thereof, provided that at the time of submission of the plans and specifications to Landlord Tenant shall include the
following legend displayed prominently at the top of the first page of Tenant’s notice delivered concurrently with said plans and specifications: “TEN/10 POST OFFICE SQUARE: THE LEASE TO BOSTON PRIVATE FINANCIAL HOLDINGS, INC.: AS
PROVIDED IN SUCH LEASE, THESE SUBMISSIONS SHALL BE DEEMED TO BE AUTOMATICALLY APPROVED IF YOU DO NOT RESPOND WITHIN FIFTEEN (15) BUSINESS DAYS AFTER RECEIPT.” 
 At the time Landlord approves any of Tenant’s Alterations Landlord shall notify Tenant which of the subject Alterations,
if any, constitute Specialty Alterations which may be required to be removed by Tenant at the end of the Term, provided that Tenant shall include the following legend in capitalized and bold type displayed

  

 -20- 

 
prominently on the top of the first page of Tenant’s notice delivered concurrently with such plans and specifications: “IF LANDLORD FAILS TO NOTIFY TENANT AT THE TIME LANDLORD
APPROVES THESE PLANS AND SPECIFICATIONS THAT ANY ALTERATIONS SHOWN THEREON ARE SPECIALTY ALTERATIONS (AS DEFINED IN THE LEASE), LANDLORD MAY NOT REQUIRE TENANT TO REMOVE SUCH SPECIALTY ALTERATIONS AT THE END OF THE TERM OF THE LEASE.”

 All Alterations shall be performed in accordance with (x) the provisions of the Rules and Regulations
attached hereto as Exhibit E (including the requirements attached thereto as Attachment I), (y) such other Rules and Regulations as may be from time to time adopted by Landlord with respect to Alterations, and (z) with plans
and specifications meeting the requirements set forth in the Rules and Regulations and approved in advance by Landlord. All Alteration work shall be (i) be performed in a good and workmanlike manner and in compliance with all applicable laws,
ordinances and regulations; (ii) be made at Tenant’s sole cost and expense; and (iii) be coordinated with any work being performed by Landlord in such a manner as not to damage the Building or interfere with the construction or
operation of the Building. At Landlord’s request, Tenant shall, before its work is started, secure assurances satisfactory to Landlord in its reasonable discretion protecting Landlord against claims arising out of the furnishing of labor and
materials for the Alterations. If any Alterations shall involve the removal of fixtures, equipment or other property in the Premises which are not Tenant’s Removable Property, such fixtures, equipment or property shall be promptly replaced by
Tenant at its expense with new fixtures, equipment or property of like utility and of at least equal quality. Tenant shall promptly reimburse Landlord for all reasonable costs, including attorneys’, architects’, engineers’, and
consultants’ fees, incurred by Landlord in connection with any request from Tenant pursuant to this Section 5.2. 
 (b) All articles of personal property and all movable fixtures, machinery and equipment and furniture owned or installed by Tenant solely at its expense in the Premises (“Tenant’s Removable
Property”) shall remain the property of Tenant and may be removed by Tenant at any time prior to the expiration or earlier termination of the Term, provided that Tenant, at its expense, shall repair any damage to the Premises or the
respective Building caused by such installation or removal. Tenant shall remove, at its expense, on the expiration or earlier termination of this Lease, all cabling installed in or at the Premises after June 1, 2004. On or prior to the
Expiration Date, Tenant shall, (i) in consideration of the agreement by Landlord not to require Tenant to remove Alterations installed in the Premises prior to the commencement of the Term of this Lease, pay to Landlord a surrender fee of
$25,000.00, and (ii) unless otherwise directed by Landlord and subject to the provisions of Section 12.2, at Tenant’s expense, remove all Specialty Alterations from the Premises and close up any slab penetrations in the Premises,
installed after the Commencement Date. Tenant shall repair and restore, in a good and workmanlike manner, any damage to the Premises or the Property caused by Tenant’s removal of any Alterations or by the closing of any slab penetrations, and
upon default thereof, Tenant shall reimburse Landlord for Landlord’s cost of repairing and restoring such damage. Any Specialty Alterations or Tenant’s

  

 -21- 

 
Removable Property not so removed shall be deemed abandoned and Landlord may retain or remove and dispose of same, and repair and restore any damage caused thereby, at Tenant’s cost and
without accountability to Tenant. All other Alterations shall become Landlord’s property upon expiration or termination of this Lease. 
 (c) Notice is hereby given that Landlord shall not be liable for any labor or materials furnished or to be furnished to Tenant upon credit, and that no mechanic’s or other lien for any such labor or
materials shall attach to or affect the reversion or other estate or interest of Landlord in and to the Premises, the Buildings or the Property. To the maximum extent permitted by law, before such time as any contractor commences to perform work on
behalf of Tenant, such contractor (and any subcontractors) shall furnish a written statement acknowledging the provisions set forth in the prior clause. Tenant agrees to pay promptly when due the entire cost of any work done on behalf of Tenant, its
agents, employees or independent contractors, and not to cause or permit any liens for labor or materials performed or furnished in connection therewith to attach to all or any part of the Property and immediately to discharge any such liens which
may so attach. If, notwithstanding the foregoing, any lien is filed against all or any part of the Property for work claimed to have been done for, or materials claimed to have been furnished to, Tenant or its agents, employees or independent
contractors, Tenant, at its sole cost and expense, shall cause such lien to be dissolved promptly after receipt of notice that such lien has been filed, by the payment thereof or by the filing of a bond sufficient to accomplish the foregoing. If
Tenant shall fail to discharge any such lien, Landlord may, at its option, discharge such lien and treat the cost thereof (including attorneys’ fees incurred in connection therewith) as Additional Rent payable upon demand, it being expressly
agreed that such discharge by Landlord shall not be deemed to waive or release the Event of Default in not discharging such lien. Tenant shall indemnify and hold Landlord harmless from and against any and all expenses, liens, claims, liabilities and
damages based on or arising, directly or indirectly, by reason of the making of any Alterations by or on behalf of Tenant to the Premises under this Section, which obligation shall survive the expiration or termination of this Lease. 
 (d) In the course of any work being performed by Tenant (including, without limitation, the “field installation” of
any Tenant’s Removable Property), Tenant agrees to use labor compatible with that being employed by Landlord for work in the Buildings or on the Property or other buildings owned by Landlord or its affiliates (which term, for purposes hereof,
shall include, without limitation, entities which control or are under common control with or are controlled by Landlord or, if Landlord is a partnership or limited liability company, by any partner or member of Landlord) and not to employ or permit
the use of any labor or otherwise take any action which might result in a labor dispute involving personnel providing services in the Buildings or on the Property pursuant to arrangements made by Landlord. 
 (e) If Tenant shall make or cause to be made at its own expense any Alteration to the Premises which shall result in an
increase in the Taxes (as evidenced by the official records of the office of the tax assessor), then Tenant shall pay, in addition to the Basic Rent, Escalation Charges and other Additional Rent, the entire increase in such Taxes attributable to
such Alteration. 
  

 -22- 

 5.3 Extra Hazardous Use. Tenant covenants and agrees that Tenant will not do
or permit anything to be done in or upon the Premises, or bring in anything or keep anything therein, which shall increase the rate of property or liability insurance on the Premises or the Property above the standard rate applicable to Premises
being occupied for the Permitted Uses. Landlord confirms that the use of the Premises principally and primarily for the operation of first-class executive business offices and bank facilities in a manner and fashion consistent with the existing use
of the Premises by Tenant will not breach the foregoing covenant. If the premium or rates payable with respect to any policy or policies of insurance carried by or on behalf of Landlord with respect to the Property increases as a result of any act
or activity on or use of the Premises during the Term or payment by the insurer of any claim arising from any act or neglect of Tenant, its employees, agents, contractors or invitees, Tenant shall pay such increase, from time to time, within fifteen
(15) days after demand therefor by Landlord, as Additional Rent. 
 5.4 Hazardous Materials. 
 (a) In order to conduct its business at the Premises and to maintain and operate the business machines located in the
Premises, Tenant may, in accordance with all applicable Environmental Laws, use chemicals and cleaning materials such as adhesives, lubricants, ink, solvents and cleaning fluids and substances of the kind and in amounts and in the manner customarily
found and used in first-class business offices. Tenant shall not use, store, handle, treat, transport, release or dispose of any other Hazardous Materials on or about the Premises or the Property without Landlord’s prior written consent, which
Landlord may withhold or condition in Landlord’s sole discretion. 
 (b) Any handling, treatment,
transportation, storage, disposal or use of Hazardous Materials by Tenant or Tenant’s agents, contractors, employees or invitees, in or about the Premises or the Property shall comply with all applicable Environmental Laws. Tenant shall, within
ten (10) Business Days of Landlord’s written request therefor, disclose in writing all Hazardous Materials that are being used by Tenant in the Premises, the nature of such use and the manner of storage and disposal. Without
Landlord’s prior written consent, Tenant shall not conduct any sampling or investigation of soil or groundwater on the Property to determine the presence of any constituents therein. 
 (c) Tenant shall indemnify, defend upon demand with counsel reasonably acceptable to Landlord, and hold Landlord harmless
from and against, any liabilities, losses, claims, damages, interest, penalties, fines, attorneys’ fees, experts’ fees, court costs, remediation costs, and other expenses which arise out of or result from the use, storage, handling,
treatment, transportation, release, threat of release or disposal of Hazardous Materials in or about the Premises or the Property by Tenant or Tenant’s agents, employees, contractors or invitees. The provisions of this paragraph (c) shall
survive the expiration or earlier termination of this Lease. 
  

 -23- 

 (d) Tenant shall give written notice to Landlord as soon as reasonably
practicable of (i) any communication received by Tenant from any governmental authority concerning Hazardous Materials which relates to the Premises or the Property, and (ii) any Environmental Condition of which Tenant is aware.

 ARTICLE 6 
 ASSIGNMENT AND SUBLETTING 
 6.1 Prohibition.

 (a) Tenant covenants and agrees that neither this Lease nor the Term and estate hereby granted, nor any
interest herein or therein, will be assigned, mortgaged, pledged, encumbered or otherwise transferred, whether voluntarily, involuntarily, by operation of law or otherwise, and that neither the Premises nor any part thereof will be encumbered in any
manner by reason of any act or omission on the part of Tenant, or used or occupied or permitted to be used or occupied, by anyone other than Tenant, or for any use or purpose other than the Permitted Uses, or be sublet (which term, without
limitation, shall include granting of concessions, licenses and the like) in whole or in part, or be offered or advertised for assignment or subletting by Tenant or any person acting on behalf of Tenant, without, in each case, the prior written
consent of Landlord. Without limiting the foregoing, any agreement pursuant to which: (x) Tenant is relieved from the obligation to pay, or a third party agrees to pay on Tenant’s behalf, all or any portion of the Basic Rent or Additional
Rent under this Lease; and/or (y) a third party undertakes or is granted by or on behalf of Tenant the right to assign or attempt to assign this Lease or sublet or attempt to sublet all or any portion of the Premises, shall for all purposes
hereof be deemed to be an assignment of this Lease and subject to the provisions of this Article 6. The provisions of this paragraph (a) shall apply to a transfer (by one or more transfers) of a controlling portion of or
interest in the stock or partnership or membership interests or other evidences of equity interests of Tenant as if such transfer were an assignment of this Lease; provided that if equity interests in Tenant at any time are or become traded on a
public stock exchange, the transfer of equity interests in Tenant on a public stock exchange shall not be deemed an assignment within the meaning of this Article. 
 (b) The provisions of paragraph (a) shall not apply to either (x) transactions with an entity into or with
which Tenant is merged or consolidated, or to which all or substantially all of Tenant’s assets are transferred, or (y) transactions with any entity which controls or is controlled by Tenant or is under common control with Tenant; provided
that in any such event: 
 (i) the successor to Tenant has a net worth, computed in accordance with generally
accepted accounting principles consistently applied, at least equal to the net worth of Tenant immediately prior to such merger, consolidation or transfer, 
  

 -24- 

 (ii) proof satisfactory to Landlord of such net worth shall have been
delivered to Landlord at least ten (10) days prior to the effective date of any such transaction, and 
 (iii) the assignee agrees directly with Landlord, by written instrument in form and content satisfactory to Landlord in its reasonable discretion, to be bound by all the obligations of Tenant hereunder, including, without limitation, the
covenant against further assignment and subletting. 
 6.2 Acceptance of Rent. If this Lease be assigned, or if
the Premises or any part thereof be sublet or occupied by anyone other than Tenant, whether or not in violation of the terms and conditions of the Lease, Landlord may, at any time and from time to time, collect rent and other charges from the
assignee, subtenant or occupant, and apply the net amount collected to the rent and other charges herein reserved, but no such assignment, subletting, occupancy, collection or modification of any provisions of this Lease shall be deemed a waiver of
this covenant, or the acceptance of the assignee, subtenant or occupant as a tenant or a release of Tenant from the further performance of covenants on the part of Tenant to be performed hereunder. Any consent by Landlord to a particular assignment,
subletting or occupancy or other act for which Landlord’s consent is required under paragraph (a) of Section 6.1 shall not in any way diminish the prohibition stated in paragraph (a) of
Section 6.1 as to any further such assignment, subletting or occupancy or other act or the continuing liability of the original named Tenant. No assignment or subletting hereunder shall relieve Tenant from its obligations hereunder, and
Tenant shall remain fully and primarily liable therefor. Landlord may revoke any consent by Landlord to a particular assignment, subletting or occupancy if the assignment or sublease does not provide that the assignee, subtenant or other occupant
agrees to be independently bound by and upon all of the covenants, agreements, terms, provisions and conditions set forth in this Lease on the part of Tenant to be kept and performed. Tenant shall promptly reimburse Landlord for all reasonable
costs, including attorneys’ fees, incurred by Landlord in connection with any request from Tenant regarding assignment or subletting or any other act that is subject to Section 6.1. 
 6.3 Excess Payments. If Tenant assigns this Lease or sublets the Premises or any portion thereof, Tenant shall pay to Landlord
as Additional Rent fifty percent (50%) of the amount, if any, by which (a) any and all compensation received by Tenant as a result of such assignment or subletting, net of reasonable expenses actually incurred by Tenant in connection with
such assignment or subletting (prorated over the term of the assignment or subletting), exceeds (b) in the case of an assignment, the Basic Rent and Additional Rent under this Lease, and in the case of a subletting, the portion of the Basic
Rent and Additional Rent allocable to the portion of the Premises subject to such subletting. Such payments shall be made on the date the corresponding payments under this Lease are due. Notwithstanding the foregoing, the provisions of this Section
shall impose no obligation on Landlord to consent to an assignment of this Lease or a subletting of all or a portion of the Premises. 
 6.4 Tenant’s Notice. If Tenant desires to assign this Lease or sublet all or any portion of the Premises, Tenant shall give notice thereof to Landlord, which shall be accompanied by (a) with respect to an assignment
of this Lease, the date Tenant desires the

  

 -25- 

 
assignment to be effective, and (b) with respect to a sublet of all or a part of the Premises, a description of the portion of the Premises to be sublet, the commencement date of such
sublease and the rent per rentable square foot Tenant will ask for such portion of the Premises. Except with respect to an assignment or sublease to a Related Entity (as defined in Section 6.6), such notice shall be deemed an irrevocable offer
from Tenant to Landlord of 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 sublease which is scheduled to expire prior to the date which is one (1) year prior to the Expiration Date, which sublease (together with all other subleases, if any)
would result in 50% or more of the rentable square footage of the Premises being sublet (excluding subleases to Related Entities and/or Affiliates of Tenant), to terminate this Lease with respect to the entire Premises. Such option may be exercised
by notice from Landlord to Tenant within thirty (30) days after delivery of Tenant’s notice. If Landlord exercises its option to terminate all or such portion of this Lease, (a) this Lease shall end and expire with respect to all or
such portion of the Premises, as the case may be, on the date that such assignment or sublease was to commence, provided that such date is in no event earlier than 90 days after the date of the above notice unless Landlord agrees to such earlier
date, (b) Rent shall be apportioned, paid or refunded as of such date, (c) the Landlord and Tenant 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, and (d) Landlord shall be free to lease the Premises (or any part thereof) to any person, including, without limitation, to Tenant’s prospective assignee or subtenant. 
 6.5 Conditions to Assignment/Subletting. (a) If Landlord does not exercise Landlord’s termination option provided
under Section 6.4 and provided that no Event of Default then exists, Landlord’s consent to a proposed assignment or subletting shall not be unreasonably withheld or delayed, provided that: 
 (i) in Landlord’s reasonable judgment, the proposed assignee or sublessee (the “Transferee”) is engaged in a business
or activity, and the Premises will be used in a manner, which (1) is in keeping with the then established standards of the Property, (2) is for any of the Permitted Uses, and (3) does not violate any restrictions set forth in this
Lease, any Mortgage or any negative covenant as to use of the Premises required by any other lease in the Property; 
 (ii) the
Transferee is reputable with sufficient financial means to perform all of its obligations under this Lease or the sublease, as the case may be; 
 (iii) if Landlord has, or reasonably expects to have within 3 months thereafter, comparable space available in the Property, neither the Transferee nor any person or entity which, directly or indirectly,
controls, is controlled by, or is under common control with, the Transferee is then an occupant of the Property; 
 (iv) the
Transferee is not a person or entity (or affiliate of a person or entity) with whom Landlord is then or has been within the prior 3 months negotiating in connection with the rental of space in the Property; 
  

 -26- 

 (v) there shall be not more than 2 subtenants in each floor of the Premises; 
 (vi) the aggregate consideration to be paid by the Transferee under the terms of the proposed sublease shall not be less than 90% of the
fixed rent at which Landlord is then offering to lease other space in the respective Building (the “Market Sub-rent”) determined as though the Premises were vacant and taking into account (1) the length of the term of the
proposed sublease; (2) any rent concessions granted to Transferee, and (3) the cost of any Alterations being performed for the Transferee; 
 (vii) Tenant shall, upon demand, reimburse Landlord for all reasonable expenses incurred by Landlord in connection with such assignment or sublease, including any investigations as to the acceptability of
the Transferee and all legal costs reasonably incurred in connection with the granting of any requested consent; 
 (viii)
Tenant shall not list the Premises to be sublet or assigned with a broker, agent or other entity or otherwise offer the Premises for subletting at a rental rate less than the Market Sub-rent; and 
 (ix) the Transferee shall not be entitled, directly or indirectly, to diplomatic or sovereign immunity, regardless of whether the Transferee
agrees to waive such diplomatic or sovereign immunity, and shall be subject to the service of process in, and the jurisdiction of the courts of, the Commonwealth of Massachusetts. 
 (b) With respect to each and every subletting and/or assignment approved by Landlord under the provisions of this Lease: 
 (i) the form of the proposed assignment or sublease shall be reasonably satisfactory to Landlord; 
 (ii) no sublease shall be for a term ending later than one day prior to the Expiration Date; 
 (iii) no Transferee shall take possession of any part of the Premises, until an executed counterpart of such sublease or assignment has
been delivered to and approved by Landlord; 
 (iv) if a material Event of Default occurs prior to the effective date of such
assignment or subletting, then Landlord’s consent thereto, if previously granted, shall be immediately deemed revoked without further notice to Tenant, and if such assignment or subletting would have been permitted without Landlord’s
consent, such permission shall be void and without force and effect, and in either such case, any such assignment or subletting shall constitute a further Event of Default hereunder; and 
 (v) each sublease shall be subject and subordinate to this Lease and to the matters to which this Lease is or shall be subordinate; and
Tenant and each Transferee shall

  

 -27- 

 
be deemed to have agreed that upon the occurrence and during the continuation of an Event of Default hereunder, Tenant has hereby assigned to Landlord, and Landlord may, at its option, accept
such assignment of, all right, title and interest of Tenant as sublandlord under such sublease, together with all modifications, extensions and renewals thereof then in effect and such Transferee shall, at Landlord’s option, attorn to Landlord
pursuant to the then executory provisions of such sublease, except that Landlord shall not be (A) liable for any previous act or omission of Tenant under such sublease, (B) subject to any counterclaim, offset or defense not expressly
provided in such sublease, which theretofore accrued to such Transferee against Tenant, (C) bound by any previous modification of such sublease not consented to by Landlord or by any prepayment of more than one month’s rent, (D) bound
to return such Transferee’s security deposit, if any, except to the extent Landlord shall receive actual possession of such deposit and such Transferee shall be entitled to the return of all or any portion of such deposit under the terms of its
sublease, or (E) obligated to make any payment to or on behalf of such Transferee, or to perform any work in the sublet space or the respective Building, or in any way to prepare the subleased space for occupancy, beyond Landlord’s
obligations under this Lease. The provisions of this Section 6.5(b)(v) shall be self-operative, and no further instrument shall be required to give effect to this provision, provided that the Transferee shall execute and deliver to
Landlord any instruments Landlord may reasonably request to evidence and confirm such subordination and attornment. 
 6.6
Related Entities. Tenant may also, (i) upon prior notice to, and with the prior written consent of Landlord (which consent shall not be unreasonably withheld or delayed), permit any Related Entity to sublet all or part of the
Premises for the Permitted Uses, and (ii) upon prior notice to Landlord, permit any Affiliate of Boston Private Financial Holdings to sublet all or part of the Premises for the Permitted Uses, provided that such Related Entity or Affiliate, as
applicable, is of a character and engaged in a business which is in keeping with the standards for the Building and for so long as such entity remains a Related Entity or Affiliate, as applicable. Such sublease shall not be deemed to vest in any
such Related Entity any right or interest in this Lease nor shall it relieve, release, impair or discharge any of Tenant’s obligations hereunder. Notwithstanding the foregoing, Tenant shall have no right to sublease all or any portion of the
Premises without Landlord’s consent pursuant to this Section 6.6 if Tenant is not the initial Tenant herein named or a person or entity who acquired Tenant’s interest in this Lease in a transaction expressly and specifically
approved by Landlord. 
 6.7 Further Requirements. Tenant shall reimburse Landlord on demand, as Additional Rent,
for any out-of-pocket costs (including reasonable attorneys’ fees and expenses) incurred by Landlord in connection with any actual or proposed assignment or sublease or other act described in paragraph (a) of
Section 6.1, whether or not consummated, including the costs of making investigations as to the acceptability of the proposed assignee or subtenant. Any sublease or assignment to which Landlord gives its consent shall not be valid or
binding on Landlord unless and until Tenant and the sublessee or assignee, as applicable, execute a consent agreement in form and substance satisfactory to Landlord in its reasonable discretion and a fully executed counterpart of such sublease or
assignment agreement, as applicable, has been delivered to Landlord.

 RESPONSIBILITY FOR REPAIRS AND CONDITION OF PREMISES; SERVICES TO 
 BE FURNISHED BY LANDLORD 
 7.1 Landlord Repairs. 
 (a) Except as otherwise provided in this Lease, Landlord agrees to keep in good order, condition and repair the roof, public
areas, exterior walls (including exterior glass), floor slabs and other structural elements of the floors, and structure of the Buildings (including all plumbing, mechanical and electrical systems installed by Landlord, but specifically excluding
any supplemental heating, ventilation or air conditioning equipment or systems installed at Tenant’s request or as a result of Tenant’s requirements in excess of building standard design criteria), all insofar as they affect the Premises,
except that Landlord shall in no event be responsible to Tenant for the repair of glass in the Premises, the doors (or related glass and finish work) leading to the Premises, or any condition in the Premises or the Buildings arising out of or
resulting from any act or neglect of Tenant, its agents, employees, invitees or contractors. Landlord shall also keep and maintain all Common Facilities in a good and clean order, condition and repair, free of snow and ice and accumulation of dirt
and rubbish, and shall keep and maintain all landscaped areas on the Property in a neat and orderly condition. Landlord shall not be responsible to make any improvements or repairs to the Buildings other than as expressly in this
Section 7.1 provided, unless expressly provided otherwise in this Lease. 
 (b) Landlord shall never
be liable for any failure to make repairs which Landlord has undertaken to make under the provisions of this Section 7.1 or elsewhere in this Lease, unless Tenant has given notice to Landlord of the need to make such repairs, and
Landlord has failed to commence to make such repairs within a reasonable time after receipt of such notice, or fails to proceed with reasonable diligence to complete such repairs. 
 7.2 Tenant Repairs. 
 (a) Tenant will keep the Premises and every part thereof neat and clean, and will maintain the same in good order, condition and repair, excepting only those repairs for which Landlord is responsible
under the terms of this Lease, reasonable wear and tear of the Premises, and damage by fire or other casualty or as a consequence of the exercise of the power of eminent domain; and Tenant shall surrender the Premises, at the end of the Term, in
such condition. Without limitation, Tenant shall comply with, and shall cause the Premises to comply with, all laws, regulations, codes and ordinances from time to time in effect, and all directions, rules and regulations of governmental agencies
having jurisdiction, and the standards recommended by the Board of Fire Underwriters, and shall, at Tenant’s expense, obtain all permits, licenses and the like required thereby. Subject to Section 10.4 regarding waiver of
subrogation, Tenant shall be responsible for the cost of repairs which may be made necessary by reason of damage to either Building arising out of or resulting from any act or neglect of Tenant, or its contractors or invitees (including any damage
by fire or other casualty arising therefrom), excepting only to the extent such damage is caused by the negligent acts or misconduct of Landlord or the agents of Landlord. 
  

 -29- 

 (b) If repairs are required to be made by Tenant pursuant to the terms
hereof, and Tenant fails to make the repairs, upon not less than thirty (30) days’ prior written notice (except that no notice shall be required in the event of an emergency), Landlord may elect to make or cause such repairs to be made
(but shall not be required to do so), and the provisions of Section 14.4 shall be applicable to the costs thereof. Landlord shall not be responsible to Tenant for any loss or damage whatsoever that may accrue to Tenant’s stock or
business by reason of Landlord’s making such repairs. 
 7.3 Floor Load - Heavy Machinery. 
 (a) Tenant shall not place a load upon any floor in the Premises exceeding the floor load per square foot of area which such
floor was designed to carry and which is allowed by law. The maximum floor load throughout the Premises is 75 pounds per square foot “live load.” Landlord reserves the right to prescribe the weight and position of all business machines and
mechanical equipment, including safes, which shall be placed so as to distribute the weight. Business machines and mechanical equipment shall be placed and maintained by Tenant at Tenant’s expense in settings sufficient, in Landlord’s
judgment, to absorb and prevent vibration, noise and annoyance. Tenant shall not move any safe, heavy machinery, heavy equipment, freight, bulky matter or fixtures into or out of the Building without Landlord’s prior consent, which consent may
include a requirement to provide insurance, naming Landlord as an insured, in such amounts as Landlord may deem reasonable. 
 (b) If any such safe, machinery, equipment, freight, bulky matter or fixtures requires special handling, Tenant agrees to employ only persons holding a Master Rigger’s License to do such work, and
that all work in connection therewith shall comply with applicable laws and regulations. Any such moving shall be at the sole risk and hazard of Tenant, and Tenant will exonerate, indemnify and save Landlord harmless against and from any liability,
loss, injury, claim or suit resulting directly or indirectly from such moving. 
 7.4 Utility Services.

 (a) Landlord shall, on Business Days from 8:00 a.m. to 6:00 p.m. and on Saturdays from 9:00 a.m. to 1:00 p.m.,
furnish heating and cooling as normal seasonal changes may require to provide reasonably comfortable space temperature and ventilation for occupants of the Premises under normal business operation at an occupancy of not more than one person per 125
square feet of Premises Rentable Area and an electrical load not exceeding 3.0 watts per square foot of Premises Rentable Area. If Tenant shall require air conditioning, heating or ventilation outside the hours and days above specified, Landlord may
furnish such service and Tenant shall pay therefor such charges as may from time to time be in effect for the Building upon demand as Additional Rent. The overtime HVAC charge is currently $40.00 per hour per floor and is subject to

  

 -30- 

 
increase from time to time by Landlord. In the event Tenant introduces into the Premises personnel or equipment which overloads the capacity of the Building system or in any other way interferes
with the ability of the base building HVAC to perform adequately its proper functions, supplementary systems may, if and as needed, at Landlord’s option, be provided by Landlord, and the cost of such supplementary systems shall be payable by
Tenant to Landlord upon demand as Additional Rent. Tenant shall not install any supplementary or auxiliary HVAC equipment to serve the Premises without Landlord’s prior consent in each instance. The work to install any such supplementary or
auxiliary HVAC equipment shall be considered to be an Alteration for all purposes under this Lease and Tenant shall comply with all terms and conditions of this Lease in connection therewith. Without limitation, the plans and specifications for any
such supplementary or auxiliary HVAC equipment and the installation and maintenance thereof, shall be subject to Landlord’s prior approval in each instance. The installation, maintenance, operation and repair of any such supplementary or
auxiliary HVAC equipment shall be performed by Tenant at its sole cost and expense and Landlord shall have no obligations or liabilities in connection therewith. 
 (b) Landlord shall supply electricity to the Premises to meet a demand requirement not to exceed 3.0 watts per rentable
square foot of the respective area of the Premises for standard single-phase 120 volt alternating current, and Tenant agrees in its use of the Premises (i) not to exceed such requirements, and (ii) that its total connected lighting load it
will not exceed the maximum from time to time permitted under applicable governmental regulations. If, without in any way derogating from the foregoing limitation, Tenant shall require electricity in excess of the requirements set forth above,
Tenant shall notify Landlord and Landlord may (without being obligated to do so) supply such additional service or equipment at Tenant’s sole cost and expense. Landlord shall purchase and install, at Tenant’s expense, all lamps, tubes,
bulbs, starters and ballasts. In order to assure that the foregoing requirements are not exceeded and to avert possible adverse effect on the Building’s electric system, Tenant shall not, without Landlord’s prior consent, connect any
fixtures, appliances or equipment to the Building’s electric distribution system other than personal computers, facsimile transceivers, typewriters, pencil sharpeners, adding machines, photocopiers, word and data processors, clocks, radios,
hand-held or desk top calculators, dictaphones, desktop computers and other similar small electrical equipment normally found in business offices and not drawing more than [15 amps at 120/208 volts]. All charges to Tenant under this paragraph
shall be due and payable as Additional Rent within thirty (30) days after receiving Landlord’s invoice therefor. 
 (c) Landlord has installed check meters to measure the consumption of electricity in the portions of the Premises in the Ten P.O. Square Building. Tenant shall pay to Landlord, as Additional Rent, within
ten (10) Business Days after receipt of Landlord’s invoice therefor, the costs of all electricity consumed in such portions of the Premises, based on the amounts shown on said check meters. Said payments shall be based upon the actual
out-of-pocket costs incurred by Landlord in providing electrical service, which costs may include, without limitation, energy charges, demand charges, surcharges, time-of-day charges, the cost of generation, transmission and distribution

  

 -31- 

 
services, stranded cost charges, taxes and other charges. If Landlord so elects, from time-to-time, Landlord may furnish a notice to Tenant increasing or adjusting the electricity charges and
thereafter Tenant shall pay the increased or adjusted electricity charges in accordance with Landlord’s notice. Said adjustments may be based upon (i) increased consumption as measured by said check meters, or (ii) increases in the
actual out-of-pocket costs and expenses incurred by Landlord in connection with providing said electricity. 
 (d) Landlord has installed separate meters to measure the consumption of electricity in the portions of the Premises in the 10 P.O. Square Building. Tenant shall contract directly with the public utility company furnishing electric service
to the 10 P.O. Square Building for electric service to the Premises. Tenant shall pay all amounts payable to the utility company, on a timely basis, and in all events prior to the due date thereof. Tenant shall maintain the meters in good working
order and repair. If Tenant fails to maintain such meters or to pay such charges on a timely basis, then Landlord may repair or replace such meters and/or pay such charges directly to the utility company and Tenant shall reimburse Landlord as
Additional Rent for all amounts expended by Landlord in connection therewith within ten (10) days after receipt of a bill therefor. 
 (e) From time to time during the Term of this Lease, either Landlord or Tenant shall have the right to have an electrical consultant acceptable to both parties in their reasonable discretion make a survey
of Tenant’s electric usage. In the event that such survey shows that Tenant has exceeded the requirements set forth in paragraph (b), in addition to any other rights Landlord may have hereunder, Tenant shall, upon demand, reimburse
Landlord for the cost of such survey and the cost, as determined by such consultant, of electricity usage in excess of such requirements as Additional Rent. 
 (f) Landlord shall have the right to discontinue furnishing electricity to the Premises at any time upon not less than thirty
(30) days’ notice to Tenant; provided that Landlord shall, at Tenant’s expense, separately meter the Premises directly to the applicable public utility company. If Landlord exercises such right, from and after the effective date of
such discontinuance, Landlord shall not be obligated to furnish electricity to the Premises, and in the computation of Operating Expenses, only the cost of electricity supplied to those portions of the Building other than those leased or intended to
be leased to tenants for their exclusive use and occupancy, i.e., the Common Facilities, shall be included; and 
 (g) Landlord shall permit Landlord’s existing wires, risers, conduits and other electrical equipment of Landlord to be used to supply electricity to Tenant, provided that the limits set forth in paragraph (b) shall not be
exceeded, and Tenant shall be responsible for payment of all electricity charges directly to such utility. 
 7.5 Other
Services. 
 Landlord shall also provide the following: 
 (a) Passenger elevator service from the existing passenger elevator system in common with Landlord and others entitled
thereto. 
  

 -32- 

 (b) Warm water for lavatory purposes and cold water (at temperatures
supplied by the city in which the Property is located) for drinking, lavatory and toilet purposes. If Tenant uses water for any purpose other than for ordinary lavatory and drinking purposes, Landlord may assess a reasonable charge for the
additional water so used, or install a water meter and thereby measure Tenant’s water consumption for all purposes. In the latter event, Tenant shall pay the cost of the meter and the cost of installation thereof as Additional Rent upon demand
and shall keep such meter and installation equipment in good working order and repair. Tenant agrees to pay for water consumed, as shown on such meter, together with the sewer charge based on such meter charges, as and when bills are rendered, and
in the event Tenant fails timely to make any such payment, Landlord may pay such charges and collect the same from Tenant upon demand as Additional Rent. 
 (c) Cleaning and janitorial services to the Premises, provided the same are kept in order by Tenant, substantially in accordance with the cleaning standards set forth in Exhibit I attached hereto,
as the same may be modified, amended, supplemented or replaced from time to time by Landlord in its reasonable discretion. 
 (d) Access to the Premises at all times, subject to security precautions from time to time in effect, if any, and subject always to restrictions based on emergency conditions. The Milk Street entrance to
the Ten P.O. Square Building provides a 24-hour security checkpoint for after hours access to the Ten P.O. Square Building. Any security devices required by Tenant, and the installation thereof, shall be at Tenant’s sole cost and expense

 Landlord may from time to time, but shall not be obligated to, provide one or more attendants in or about the lobby areas of
the respective Building, and the costs of such services shall constitute Operating Expenses in accordance with the provisions of Article 9 hereof. Tenant expressly acknowledges and agrees that, if provided: (i) such attendants shall not
serve as police officers, and will be unarmed, and will not be trained in situations involving potentially physical confrontation; and (ii) such attendants will be solely an amenity to tenants of the respective Building for purposes such as
assisting visitors and invitees of tenants and others in the respective Building, monitoring fire control and alarm equipment, and summoning emergency services to the respective Building as and when needed, and not for the purpose of securing any
individual tenant premises or guaranteeing the physical safety of Tenant’s Premises or of Tenant’s employees, agents, contractors or invitees. If and to the extent that Tenant desires to provide security for the Premises or for such
persons or their property, Tenant shall be responsible for so doing, after having first consulted with Landlord and after obtaining Landlord’s consent, which shall not be unreasonably withheld. Landlord expressly disclaims any and all
responsibility and/or liability for the physical safety of Tenant’s property, and for that of Tenant’s employees, agents, contractors and invitees, and, without in any way limiting the operation of Article 10 hereof, Tenant, for
itself and its agents, contractors, invitees and employees, hereby expressly waives any claim, action, cause of action or other right which may

  

 -33- 

 
accrue or arise as a result of any damage or injury to the person or property of Tenant or any such agent, invitee, contractor or employee. Tenant agrees that, as between Landlord and Tenant, it
is Tenant’s responsibility to advise its employees, agents, contractors and invitees as to necessary and appropriate safety precautions. 
 Landlord shall also permit cable television providers to install wires, conduits and other necessary equipment in the Buildings and to furnish cable television service to the Premises. Tenant shall
contract directly with such cable television providers for cable television services and shall pay all amounts payable to such providers on a timely basis, including, without limitation, all subscription, maintenance and repair costs and expenses
related thereto. 
 7.6 Interruption of Service. 
 (a) Landlord reserves the right to curtail, suspend, interrupt and/or stop the supply of water, sewage, electrical current,
cleaning, and other services, and to curtail, suspend, interrupt and/or stop use of entrances and/or lobbies serving access to either of the Buildings, or other portions of the Property, without thereby incurring any liability to Tenant, when
necessary by reason of accident or emergency, or for repairs, alterations, replacements or improvements in the judgment of Landlord reasonably exercised desirable or necessary, or when prevented from supplying such services or use due to any act or
neglect of Tenant or Tenant’s agents, employees, contractors or invitees or any person claiming by, through or under Tenant, or by Force Majeure, including, but not limited to, strikes, lockouts, difficulty in obtaining materials, accidents,
laws or orders, or inability, by exercise of reasonable diligence, to obtain electricity, water, gas, steam, coal, oil or other suitable fuel or power. Except as set forth in paragraph (b) below, no diminution or abatement of rent or
other compensation, nor any direct, indirect or consequential damages shall or will be claimed by Tenant as a result of, nor shall this Lease or any of the obligations of Tenant be affected or reduced by reason of, any such interruption,
curtailment, suspension or stoppage in the furnishing of the foregoing services or use, irrespective of the cause thereof. Except as set forth in paragraph (b) below, failure or omission on the part of Landlord to furnish any of the
foregoing services or use as provided in this paragraph shall not be construed as an eviction of Tenant, actual or constructive, nor entitle Tenant to an abatement of rent, nor to render the Landlord liable in damages, nor release Tenant from prompt
fulfillment of any of its covenants under this Lease. 
 (b) Notwithstanding anything contained in this Lease to
the contrary, if (i) an interruption or curtailment, suspension or stoppage of an Essential Service (as said term is hereinafter defined) shall occur, except any of the same due to any act or neglect of Tenant or Tenant’s agents employees,
contractors or invitees or any person claiming by, through or under Tenant (any such interruption of an Essential Service being hereinafter referred to as a “Service Interruption”), and (ii) such Service Interruption occurs or
continues as a result of the negligent acts or wrongful misconduct of the Landlord or Landlord’s agents, servants, employees or contractors, and (iii) such Service Interruption continues for more than seven (7) consecutive Business
Days after Landlord shall have received written notice thereof from Tenant, and (iv) as a result of such

  

 -34- 

 
Service Interruption despite the commercially reasonable good faith efforts of Tenant, all or substantially all of the Premises are not usable by Tenant in the usual operations of its business,
and Tenant actually ceases operating its business in all or substantially all of the Premises for such seven (7) Business Day period, then there shall be an abatement of one day’s Basic Rent and Escalation Charges for each day during which
such Service Interruption continues after such seven (7) Business Day period; provided, however, that if any part of the Premises is reasonably useable for Tenant’s normal business operations notwithstanding such Service Interruption, then
the amount of each daily abatement of Basic Rent and Escalation Charges shall only be proportionate to the nature and extent of the interruption of Tenant’s normal operations or ability to use the Premises. The provisions of this subsection
(b) shall not apply in the event of a Force Majeure event or a casualty, eminent domain event or other event governed by the provisions of Article 11. The rights granted to Tenant under this paragraph (b) shall be
Tenant’s sole and exclusive remedy resulting from a failure of Landlord to provide services, and Landlord shall not otherwise be liable for any loss or damage suffered or sustained by Tenant resulting from any failure or cessation of services.
For purposes hereof, the term “Essential Services” shall mean the following services: access to the Premises, passenger elevator service, water and sewer/septic service and electricity, but only to the extent that Landlord has an
obligation to provide same to Tenant under this Lease. Any abatement of Basic Rent under this paragraph shall apply only with respect to Basic Rent allocable to the period after each of the conditions set forth in subsections (i) through
(iv) hereof shall have been satisfied and only during such times as each of such conditions shall exist.

 (b) In the event that Ten P.O. Square Taxes during any Tax Year shall exceed Base Taxes for the Ten P.O. Square Property,
Tenant shall pay to Landlord, as an Escalation Charge, an amount equal to (i) the excess of Ten P.O. Square Taxes for such Tax Year over Base Taxes for the Ten P.O. Square Property, multiplied by (ii) Tenant’s Proportionate Ten P.O.

an Event of Default, an amount equal to such refund or reimbursement or sum in lieu thereof (exclusive of any interest, and apportioned if such refund is for a Tax Year a portion of which falls outside the Term), multiplied by the respective
Tenant’s Proportionate Share; provided, that in no event

  

 -37-

Term. 
 “Ten P.O. Square Operating Expenses” shall mean the aggregate customary costs and expenses incurred by
Landlord with respect to the operation, administration, cleaning, repair, maintenance and management of the Ten P.O. Square Property, all as set forth in Exhibit D attached hereto, provided that if during any portion of the Operating Year for

supplying all tenants with the services being supplied under this Lease, actual Ten P.O. Square Operating Expenses incurred shall be extrapolated reasonably by Landlord on an item by item basis to the estimated Ten P.O. Square Operating Expenses
that would have been incurred if the Ten P.O. Square Building were ninety-three percent (93%) occupied for such Operating Year and such services were being supplied to all tenants, and such extrapolated amount shall, for the purposes hereof, be
deemed to be the Ten P.O. Square Operating Expenses for such Operating Year. The foregoing extrapolation of Operating Expenses shall be performed with respect to those components of Operating Expenses that vary or are impacted by changes in the
occupancy of the respective Building. 
 “10 P.O. Square Operating Expenses” shall mean the aggregate customary
costs and expenses incurred by Landlord with respect to the operation, administration, cleaning, repair, maintenance and management of the 10 P.O. Square Property, all as set forth in Exhibit D attached hereto, provided that if during any

impacted by changes in the occupancy of the respective Building.

 (a) In the event that for any Operating Year the Ten P.O. Square Operating Expenses shall exceed Base Operating Expenses for
the Ten P.O. Square Property, Tenant shall pay to Landlord, as an Escalation Charge, an amount equal to (i) such excess Ten P.O. Square Operating Expenses multiplied by (ii) Tenant’s Proportionate Ten P.O. Square Share, such amount to
be apportioned for any portion of an Operating Year in which the Commencement Date falls or the Term of this Lease ends. For each Operating Year, Landlord shall not be entitled to a reimbursement from tenants for Ten P.O. Square Operating Expenses
in excess of 100% of the costs and expenses relating to the Ten P.O. Square Property actually incurred by Landlord with respect to such Operating Year. 
 (b) In the event that for any Operating Year the 10 P.O. Square Operating Expenses shall exceed Base Operating Expenses for the 10 P.O. Square Property, Tenant shall pay to Landlord, as an Escalation
Charge, an amount equal to (i) such excess 10 P.O. Square Operating Expenses multiplied by (ii) Tenant’s Proportionate 10 P.O. Square Share, such amount to be apportioned for any portion of an Operating Year in which the Commencement
Date falls or the Term of this Lease ends. For each Operating Year, Landlord shall not be entitled to a reimbursement from tenants for 10 P.O. Square Operating Expenses in excess of 100% of the costs and expenses relating to the 10 P.O. Square
Property actually incurred by Landlord with respect to such Operating Year. 
 (c) Estimated payments by Tenant
on account of Operating Expenses shall be made on the first day of each and every calendar month during the Term of this Lease, in the fashion herein provided for the payment of Basic Rent. The monthly amount so to be paid to Landlord shall be
sufficient to provide Landlord by the end of each Operating Year a sum equal to Tenant’s required payment, as reasonably estimated by Landlord from time to time during each Operating Year, on account of the Ten P.O. Square Operating Expenses
and the 10 P.O. Square Operating Expenses for such Operating Year. Promptly after the end of each Operating Year, Landlord shall submit to Tenant reasonably detailed accountings (calculated on an accrual basis) of the Ten P.O. Square Operating
Expenses and the 10 P.O. Square Operating Expenses, respectively, for such Operating Year, and Landlord shall certify to the accuracy thereof. If estimated payments theretofore made for such Operating Year by Tenant exceed Tenant’s
required payment on account thereof for such Operating Year according to such statement, Landlord shall credit the amount of overpayment against subsequent obligations of Tenant with respect to Ten P.O. Square Operating Expenses and/or 10 P.O.
Square Operating Expenses (or promptly refund such overpayment if the Term of this Lease has ended and Tenant has no further obligation to Landlord); but if the required payments on account thereof for such Operating Year are greater than the
estimated payments (if any) theretofore made on account thereof for such Operating Year, Tenant shall make payment to Landlord within thirty (30) days after being so advised by Landlord, and the obligation to make such payment for any period
within the Term shall survive expiration of the Term. 
  

 -39- 

 (d) Each statement with respect to Operating Expenses sent to Tenant by
Landlord shall be conclusively binding upon Tenant, unless Tenant shall (i) pay to Landlord the amount set forth in such statement when due, without prejudice to Tenant’s right to dispute such statement, and (ii) within not more than
one hundred fifty (150) days after such statement is sent, send a notice (an “Operating Expense Dispute Notice”) to Landlord objecting to such statement and specifying the reasons for Tenant’s claim that such statement is
incorrect. Provided that Tenant shall have first paid all amounts set forth in the statement and shall have notified Landlord within said one hundred fifty (150) day period as aforesaid, then Tenant shall have the right to examine, copy and
audit Landlord’s books and records establishing Operating Expenses for any Operating Year at any time prior to the date which is one hundred and twenty (120) days following the delivery of the Operating Expense Dispute Notice. Tenant shall
give Landlord not less than thirty (30) days’ prior notice of its intention to examine and audit such books and records, and such examination and audit shall take place at such place within the continental United States as Landlord
routinely maintains such books and records, unless Landlord elects to have such examination and audit take place in another location designated by Landlord in the city and state in which the Property is located. Tenant’s review shall be
conducted solely by an auditor or accountant of a nationally recognized auditing or accounting firm and not by any party compensated by Tenant on a contingency fee arrangement. Tenant, all consultants and accountants retained by Tenant, and all
those acting on behalf of Tenant, shall execute and deliver to Landlord confidentiality agreements, in form and substance reasonably satisfactory to Landlord, whereby such parties agree not to disclose to any third party any of the information
obtained in connection with such audit or inspection, the substance of any admissions or stipulations by any party in connection therewith, or of any resulting reconciliation, compromise or settlement. All costs of the examination and audit shall be
borne by Tenant; provided, however, that if such examination and audit establishes that the actual Operating Expenses for the Operating Year in question are less than the amount set forth as the annual Operating Expenses on the annual statement
delivered to Tenant by greater than five percent (5%), then Landlord shall pay the reasonable costs of such examination and audit. If, pursuant to the audit, the payments made for such Operating Year by Tenant exceed Tenant’s required payment
on account thereof for such Operating Year, Landlord shall credit the amount of overpayment against subsequent obligations of Tenant with respect to Operating Expenses (or promptly refund such overpayment if the Term of this Lease has ended and
Tenant has no further obligation to Landlord); but, if the payments made by Tenant for such Operating Year are less than Tenant’s required payment as established by the examination and audit, Tenant shall pay the deficiency to Landlord within
thirty (30) days after conclusion of the examination and audit, and the obligation to make such payment for any period within the Term shall survive expiration of the Term. If Tenant does not elect to exercise its right to examine and audit
Landlord’s books and records for any Operating Year within the time period provided for by this paragraph, Tenant shall have no further right to challenge Landlord’s statement of Operating Expenses. 
  

 -40- 

 9.3 Utility Payments. Tenant shall be responsible for the payment of all utilities used and
consumed in the Premises. Tenant shall pay for electricity consumed in the Premises as more particularly set forth in Section 7.4. The obligation to pay for electricity used and consumed in the Premises during the Term hereof shall
survive expiration of the Term. 
 ARTICLE 10 
 INDEMNITY AND PUBLIC LIABILITY INSURANCE 
 10.1 Tenant’s
Indemnity. Except to the extent caused by the gross negligence or willful misconduct of Landlord or its agents or employees, Tenant agrees to indemnify and save harmless Landlord and Landlord’s partners, members, shareholders, officers,
directors, managers, employees, agents and contractors and any Holder from and against all claims, losses, cost, damages, liability or expenses of whatever nature arising out of or resulting from: (i) from any accident, injury or damage
whatsoever to any person, or to the property of any person, occurring in or about the Premises; (ii) from any accident, injury or damage whatsoever to any person, or to the property of any person, occurring outside of the Premises but on or
about the Property, where such accident, damage or injury results or is claimed to have resulted from any act or omission on the part of Tenant or Tenant’s agents, employees, contractors, invitees or sublessees; or (iii) the use or
occupancy of the Premises or of any business conducted therein or any thing or work whatsoever done or any condition created in or about the Premises, and, in any case, occurring after the Commencement Date (or such earlier date as of which Tenant
takes possession of the Premises) until the expiration of the Term of this Lease and thereafter so long as Tenant is in occupancy of any part of the Premises. This indemnity and hold harmless agreement shall include indemnity against all losses,
costs, damages, expenses and liabilities incurred in or in connection with any such claim or any proceeding brought thereon, and the defense thereof, including, without limitation, reasonable attorneys’ fees and costs at both the trial and
appellate levels. The provisions of this Section 10.1 shall survive the expiration or earlier termination of this Lease. 
 10.2 Tenant Insurance. Tenant agrees to maintain in full force from the date upon which Tenant first enters the Premises for any reason, throughout the Term of this Lease, and thereafter so long as Tenant is in occupancy of
any part of the Premises, (a) a policy of commercial general liability and property damage insurance (including broad form contractual liability, independent contractor’s hazard and completed operations coverage) in at least the amounts of
the Initial General Liability Insurance specified in Section 1.1 or such greater amounts as Landlord in its reasonable discretion shall from time to time request, under which Tenant is named as an insured and Landlord, and, at
Landlord’s request, Landlord’s property manager, any Holder, and such other persons as Landlord reasonably may request are named as additional insureds, and under which the insurer agrees to indemnify and hold Landlord and such other
additional named insureds harmless from and against all cost, expense and/or liability arising out of or based upon any and all claims, accidents, injuries and damages set forth in Section 10.1 and (b) a policy of
“all-risk” property insurance on a “replacement cost” basis, insuring Tenant’s Removable Property and any Alterations made by Tenant pursuant to Section 5.2, to the extent that the same have not become the
property of Landlord. Tenant may satisfy such insurance requirements by including the Premises in a so-called “blanket” and/or “umbrella” insurance policy, provided that the amount of coverage allocated to the Premises

  

 -41- 

 
pursuant to a “per location” endorsement shall fulfill the requirements set forth herein. Tenant’s insurance shall be primary to, and not contributory with any insurance carried by
Landlord, whose insurance shall be considered excess only. Each policy required hereunder shall be non-cancelable and non-amendable with respect to Landlord and Landlord’s said designees without thirty (30) days’ prior notice, shall
be written on an “occurrence” basis. and a duplicate original or certificates thereof satisfactory to Landlord, together with a photocopy of the entire policy, shall be delivered to Landlord. The policies of insurance required to be
maintained by Tenant hereunder shall be issued by companies domiciled in the United States and qualified and licensed to conduct business in the state in which the Property is located, and shall be rated A:X or better in the most current issue of
Best’s Insurance Reports. Tenant’s insurance policies shall not include deductibles in excess of Five Thousand Dollars ($5,000.00). 
 10.3 Tenant’s Risk. Tenant agrees to use and occupy the Premises and to use such other portions of the Property as Tenant is herein given the right to use at Tenant’s own risk.
Landlord shall not be liable to Tenant, its employees, agents, invitees or contractors for any damage, injury, loss, compensation, or claim (including, but not limited to, claims for the interruption of or loss to Tenant’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 Property, any fire, robbery, theft, mysterious disappearance and/or any other crime or casualty, the actions of any
other tenants of the Building or of any other person or persons, or any leakage in any part or portion of the Premises or the Building, or from water, rain or snow that may leak into, or flow from any part of the Premises or the Building, or from
drains, pipes or plumbing fixtures in the Building, unless due to the gross negligence or willful misconduct of Landlord or Landlord’s agents, contractors or employees. Any goods, property or personal effects stored or placed in or about the
Premises shall be at the sole risk of Tenant, and neither Landlord nor Landlord’s insurers shall in any manner be held responsible therefor. Landlord shall not be responsible or liable to Tenant, or to those claiming by, through or under
Tenant, 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 Property or otherwise. The
foregoing provisions of this Section 10.3 (as well as any other provisions in this Lease providing for indemnification of Landlord by Tenant) shall be deemed to be modified in each case by the insertion of the phrase: “except as
otherwise provided in Section 15 of Massachusetts General Laws Chapter 186.” Notwithstanding the foregoing, Landlord shall not be released from liability for any injury, loss, damages or liability to the extent caused by the gross
negligence or willful misconduct of Landlord, its servants, employees or agents acting within the scope of their authority on or about the Premises; provided, however, that in no event shall Landlord, its servants, employees or agents have any
liability to Tenant based on any loss with respect to or interruption in the operation of Tenant’s business. The provisions of this Section 10.3 shall be applicable from and after the execution of this Lease and until the end of the
Term of this Lease, and during such further period as Tenant may use or be in occupancy of any part of the Premises or of the Building. 
 10.4 Waiver of Subrogation. The parties hereto shall each procure an appropriate clause in, or endorsement on, any property insurance policy on the Premises or any personal property,
fixtures or equipment located thereon or therein, pursuant to which the insurer waives subrogation or consents to a waiver of right of recovery in favor of either party, its respective

  

 -42- 

 
agents or employees. Having obtained such clauses and/or endorsements, each party hereby agrees that it will not make any claim against or seek to recover from the other or its agents or
employees for any loss or damage to its property or the property of others resulting from fire or other perils covered by such property insurance regardless of the cause or origin of such loss or damage, including, but not limited to, the negligence
of such other party or its agents or employees. 
 ARTICLE 11 
 FIRE, EMINENT DOMAIN, ETC. 
 11.1
Landlord’s Right of Termination. If (i) a substantial part of the Premises, or (ii) a substantial part of the Property is (or are) substantially damaged by fire or casualty (the term “substantially damaged”
meaning damage of such a character that the same cannot, in the ordinary course, reasonably be expected to be repaired within twelve (12) months from the commencement of the repair or restoration thereof (as determined by a contractor selected
by Landlord in its reasonable discretion)), or if any part of the Property is taken by any exercise of the right of eminent domain, then Landlord shall have the right to terminate this Lease (even if Landlord’s entire interest in the Premises
may have been divested) by giving notice of Landlord’s election so to do within ninety (90) days after the occurrence of such casualty or the effective date of such taking, provided that if the Premises are not damaged or taken, Landlord
may not terminate this Lease unless Landlord similarly terminates the leases of other tenants in the respective Building aggregating at least 50% of the portion of the respective Building occupied for office purposes immediately prior to such damage
or taking. If this Lease is so terminated, (a) the Term shall expire upon the 30th day after such notice is given by Landlord, (b) Tenant shall vacate the Premises and surrender the same to Landlord, (c) Tenant’s liability for
Rent shall cease as of the date of the damage or taking, and (d) any prepaid Rent for any period after the date of the damage shall be refunded by Landlord to Tenant. 
 11.2 Restoration; Tenant’s Right of Termination. If the Premises or either of the Buildings are damaged by fire or other
casualty, and this Lease is not terminated pursuant to Section 11.1, Landlord shall thereafter use reasonable efforts to restore the respective Building and the portion of the Premises (excluding any Alterations made by Tenant pursuant
to Section 5.2) to proper condition for Tenant’s use and occupation, provided that Landlord shall not be obligated to expend more than the amount it actually receives in insurance proceeds as a result of such fire or other casualty,
and Landlord shall not be obligated to commence restoration until Landlord has received the insurance proceeds. If, for any reason (including, without limitation, the insufficiency or unavailability of insurance proceeds), full restoration shall not
be substantially completed within twelve (12) months after the expiration of the ninety-day period referred to in Section 11.1 (which twelve (12) month period may be extended for such periods of time as Landlord is prevented
from proceeding with or completing such restoration due to Force Majeure, but in no event for more than an additional three (3) months), Tenant shall have the right to terminate this Lease by giving notice to Landlord thereof within thirty
(30) days after the expiration of such period (as so extended) provided that such restoration is not completed within such period. This Lease shall cease and come to an end without further liability or obligation on the part of either party
thirty (30) days after such giving of notice by Tenant unless, within such thirty-day period, Landlord substantially completes such restoration. Such right of termination shall be Tenant’s sole and exclusive remedy at law or in equity for
Landlord’s failure so to complete such restoration, and time shall be of the essence with respect thereto. 
  

 -43- 

 11.3 Landlord’s Insurance. Landlord agrees to maintain in full force and
effect, during the Term of this Lease, property damage insurance with such deductibles and in such amounts as may from time to time be carried by reasonably prudent owners of similar buildings in the area in which the Property is located, provided
that in no event shall Landlord be required to carry other than fire and extended coverage insurance or insurance in amounts greater than 80% of the actual insurable cash value of the Building (excluding footings and foundations). Landlord also
shall maintain a policy of commercial general liability insurance, with the coverages and in the amounts as Landlord determines in its reasonable discretion to be prudent, and in any event in accordance with the requirements of all mortgagees
holding mortgages on the interest of Landlord in the Property. Landlord may satisfy such insurance requirements by including the Property in a so-called “blanket” insurance policy, provided that the amount of coverage allocated to the
Property shall fulfill the foregoing requirements. 
 11.4 Abatement of Rent. If Tenant is not in default or
breach under the Lease and the Premises or the Buildings are damaged by fire or other casualty, Basic Rent and Escalation Charges payable by Tenant shall abate proportionately for the period during which, by reason of such damage, there is
substantial interference with Tenant’s use of the Premises for the Permitted Uses, having regard for the extent to which Tenant may despite its commercially reasonable good faith efforts be required to discontinue Tenant’s use of all or an
undamaged portion of the Premises due to such damage, but such abatement or reduction shall end if and when Landlord shall have substantially completed sufficient restoration that Tenant is reasonably able to use the Premises and the Premises are in
substantially the condition in which they were prior to such damage (excluding any Alterations made by Tenant pursuant to Section 5.2). If the Premises shall be affected by any exercise of the power of eminent domain, Basic Rent and
Escalation Charges payable by Tenant shall be justly and equitably abated and reduced according to the nature and extent of the loss of use thereof suffered by Tenant. In no event shall Landlord have any liability for damages to Tenant for
inconvenience, annoyance, or interruption of business arising from any fire or other casualty or eminent domain. 
 11.5
Final 18 Months. Notwithstanding anything to the contrary in this Article 11, if any damage during the final 18 months of the Term renders the Premises wholly untenantable, either Landlord or Tenant may terminate this Lease by
notice to the other party within 30 days after the occurrence of such damage and this Lease shall expire on the 30th day after the date of such notice. For purposes of this Section 11.5, the Premises shall be deemed wholly untenantable
if Tenant shall be precluded from using more than 50% of the Premises for the conduct of its business for the Permitted Uses and Tenant’s inability to so use the Premises is reasonably expected to continue for more than 90 days. 
 11.6 Condemnation Award. Landlord shall have and hereby reserves and excepts, and Tenant hereby grants and assigns to
Landlord, all awards and rights to recover for damages to the Property and the leasehold interest hereby created, and to compensation accrued or hereafter to accrue by reason of any taking, by exercise of the right of eminent domain and Tenant shall
have no claim against Landlord or the condemning authority for the value of any

  

 -44- 

 
unexpired portion of the Term or any improvements or alterations of Tenant. By way of confirming the foregoing, Tenant hereby grants and assigns, and covenants with Landlord to grant and assign
to Landlord, all rights to such awards, damages or compensation, and covenants to deliver such further assignments and assurances thereof as Landlord may from time to time request, and Tenant hereby irrevocably appoints Landlord its attorney-in-fact
to execute and deliver in Tenant’s name all such assignments and assurances. Nothing contained herein shall be construed to prevent Tenant from prosecuting in any condemnation proceedings a separate claim for the value of any of Tenant’s
furniture, fixtures and other personal property and the unamortized value of tenant improvements installed in the Premises by Tenant solely at Tenant’s expense (as amortized on a straight-line basis over the term of this Lease, with interest at
the rate of 10% per annum) and for relocation expenses, provided that such action shall not reduce, detract from or affect the amount of compensation otherwise recoverable by Landlord from the taking authority. 
 11.7 Temporary Taking. If all or any part of the Premises is Taken temporarily during the Term for any public or quasi-public
use or purpose, Tenant shall give prompt notice to Landlord and the Term shall not be reduced or affected in any way and Tenant shall continue to pay all Rent payable by Tenant without reduction or abatement and to perform all of its other
obligations under this Lease, except to the extent prevented from doing so by the condemning authority, and Tenant shall be entitled to receive any award or payment from the condemning authority for such use, which shall be received, held and
applied by Tenant as a trust fund for payment of the Rent falling due. 
 ARTICLE 12 
 HOLDING OVER; SURRENDER 
 12.1 Holding Over. Any holding over by Tenant after the expiration of the Term of this Lease shall be treated as a daily tenancy at sufferance at a Basic Rent equal to one hundred and fifty
percent (150%) of the greater of (i) the Basic Rent then in effect plus Escalation Charges and other Additional Rent herein provided (prorated on a daily basis), and (ii) the rate Landlord is then asking for comparable space in the
Buildings (or if no comparable space is then available, the fair market rental value of the Premises, as determined by Landlord in its reasonable discretion). Tenant shall also pay to Landlord all damages, direct, indirect, or consequential
sustained by reason of any such holding over. In all other respects, such holding over shall be on the terms and conditions set forth in this Lease as far as applicable. 
 12.2 Surrender of Premises. Upon the expiration or earlier termination of the Term of this Lease, Tenant shall peaceably quit and surrender to Landlord the Premises in neat and clean
condition and in good order, condition and repair, together with all Alterations which may have been made or installed in, on or to the Premises prior to or during the Term of this Lease (except as hereinafter provided), excepting only ordinary wear
and use and damage by fire or other casualty for which, under other provisions of this Lease, Tenant has no responsibility to repair or restore. Upon the expiration or earlier termination of the Term of this Lease, Tenant shall remove (i) all
of Tenant’s Removable Property, (ii) all Specialty Alterations other than (a) Specialty Alterations which Landlord expressly confirms in writing at the time of approval of the plans for such Specialty Alteration do not need to be
removed in accordance with the

  

 -45- 

 
provisions of Section 5.2, (b) Existing Specialty Alterations (as hereinafter defined), and (c) and, to the extent specified by Landlord, all other Alterations made by
Tenant and all partitions wholly within the Premises. “Existing Specialty Alterations” shall mean the Specialty Alterations installed by Tenant in the Premises prior to the date of this Lease in accordance with the provisions of the
Existing Leases; provided, however, the Existing Specialty Alterations shall not include the alterations referred to on the Schedule of Existing Specialty Alterations to be Removed on Lease Expiration attached hereto as Exhibit J and
incorporated herein by this reference. Tenant shall repair any damage to the Premises and/or the Property caused by any such removal. Without limiting the foregoing, any Tenant’s Removable Property and/or other Alterations which shall remain in
the Buildings or on the Premises after the expiration or termination of the Term of this Lease shall be deemed conclusively to have been abandoned, and either may be retained by Landlord as its property or may be disposed of in such manner as
Landlord may see fit, at Tenant’s sole cost and expense. 
 ARTICLE 13 
 RIGHTS OF MORTGAGEES; TRANSFER OF TITLE 
 13.1 Rights of Mortgagees. 
 (a) Subject to the
provisions of this Section 13.1, this Lease shall be subordinate to any mortgage, deed of trust or ground lease or similar encumbrance (collectively, a “Mortgage”, and the holder thereof from time to time the
“Holder”) from time to time encumbering the Premises, whether executed and delivered prior to or subsequent to the date of this Lease, unless the Holder shall elect otherwise. If this Lease is subordinate to any Mortgage and the
Holder or any other party shall succeed to the interest of Landlord pursuant to the Mortgage (such Holder or other party, a “Successor”), at the election of the Successor, Tenant shall attorn to the Successor and this Lease shall
continue in full force and effect between the Successor and Tenant. Not more than fifteen (15) days after Landlord’s written request, Tenant agrees to execute such instruments of subordination or attornment in confirmation of the foregoing
agreement as the Successor reasonably may request, and provided that such instrument of subordination or attornment is in the form attached hereto as Exhibit K or is otherwise on a commercially customary form, then Tenant hereby appoints the
Successor as Tenant’s attorney-in-fact to execute such subordination or attornment agreement upon Tenant’s failure timely to comply with the Successor’s request. 
 (b) As a condition to Tenant’s agreement hereunder to subordinate Tenant’s interest in this Lease to any Mortgage,
Landlord shall obtain from each Holder, an agreement (any such agreement, a “Non-Disturbance Agreement”), in recordable form and in either (i) substantially the form of the Non-Disturbance Agreement attached hereto as
Exhibit K, or (ii) in the standard form customarily employed by such Holder (which conforms to the provisions of this Article 13 and is otherwise in commercially customary form), pursuant to which such Holder shall agree that
if and so long as no Event of Default hereunder shall have occurred, the leasehold estate granted to Tenant and the rights of Tenant pursuant to this Lease to quiet and peaceful possession of the Premises shall not be terminated, modified, affected
or disturbed by any action which

  

 -46- 

 
such Holder may take to foreclose any such Mortgage, and, except as provided in the form on Non-Disturbance Agreement attached hereto as Exhibit K, any successor landlord shall recognize
this Lease as being in full force and effect as if it were a direct lease between such successor landlord and Tenant upon all of the terms, covenants, conditions and options granted to Tenant under this Lease. 
 13.2 Assignment of Rents and Transfer of Title. 
 (a) With reference to any assignment by Landlord of Landlord’s interest in this Lease, or the rents payable hereunder,
conditional in nature or otherwise, which assignment is made to the holder of a mortgage on property which includes the Premises, Tenant agrees that the execution thereof by Landlord, and the acceptance thereof by the holder of such mortgage shall
never be treated as an assumption by such holder of any of the obligations of Landlord hereunder unless such holder shall, by notice sent to Tenant, specifically otherwise elect and, except as aforesaid, such holder shall be treated as having
assumed Landlord’s obligations hereunder only upon foreclosure of such holder’s mortgage and the taking of possession of the Premises. 
 (b) In no event shall the acquisition of Landlord’s interest in the Property by a purchaser which, simultaneously therewith, leases Landlord’s entire interest in the Property back to the seller
thereof be treated as an assumption by operation of law or otherwise, of Landlord’s obligations hereunder, but Tenant shall look solely to such seller-lessee, and its successors from time to time in title, for performance of Landlord’s
obligations hereunder. In any such event, this Lease shall be subject and subordinate to the lease to such purchaser. For all purposes, such seller-lessee, and its successors in title, shall be the Landlord hereunder unless and until Landlord’s
position shall have been assumed by such purchaser-lessor. 
 (c) Except as provided in paragraph
(b) of this Section, in the event of any transfer of title to the Property by Landlord, Landlord shall thereafter be entirely freed and relieved from the performance and observance of all covenants and obligations hereunder. 
 13.3 Notice to Mortgagee. After receiving notice from Landlord of any Holder of a Mortgage which includes the Premises, no
notice from Tenant to Landlord alleging any default by Landlord shall be effective unless and until a copy of the same is given to such Holder (provided Tenant shall have been furnished with the name and address of such Holder), and the curing of
any of Landlord’s defaults by such Holder shall be treated as performance by Landlord. 
 ARTICLE 14 
 DEFAULT; REMEDIES 
 14.1 Tenant’s Default. 
 (a) If at any time
subsequent to the date of this Lease any one or more of the following events (herein referred to as an “Event of Default”) shall occur: 
 (i) Tenant shall fail to pay the Basic Rent, Escalation Charges or any other Additional Rent hereunder when due and such failure shall continue for five (5) Business Days after notice to Tenant from
Landlord; or 
  

 -47- 

 (ii) Tenant shall neglect or fail to perform or observe any other covenant
herein contained on Tenant’s part to be performed or observed and Tenant shall fail to remedy the same within thirty (30) days after notice to Tenant specifying such neglect or failure, or if such failure is of such a nature that Tenant
cannot despite its commercially diligent good faith efforts remedy the same within such thirty (30) day period, Tenant shall fail to commence promptly (and in any event within such thirty (30) day period) to remedy the same and to
prosecute such remedy to completion with diligence and continuity; or 
 (iii) Tenant’s leasehold interest
in the Premises shall be taken on execution or by other process of law directed against Tenant; or 
 (iv) Tenant
shall make an assignment for the benefit of creditors or shall be adjudicated insolvent, or shall file any petition or answer seeking any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief for itself
under any present or future Federal, State or other statute, law or regulation for the relief of debtors (other than the Bankruptcy Code, as hereinafter defined), or shall seek or consent to or acquiesce in the appointment of any trustee, receiver
or liquidator of Tenant or of all or any substantial part of its properties, or shall admit in writing its inability to pay its debts generally as they become due; or 
 (v) An Event of Bankruptcy (as hereinafter defined) shall occur with respect to Tenant; or 
 (vi) A petition shall be filed against Tenant under any law (including, but not limited to, the Bankruptcy Code) seeking any
reorganization, arrangement, composition, readjustment, liquidation, dissolution, or similar relief under any present or future Federal, State or other statute, law or regulation and shall remain undismissed or unstayed for an aggregate of sixty
(60) days (whether or not consecutive), or if any trustee, conservator, receiver or liquidator of Tenant or of all or any substantial part of its properties shall be appointed without the consent or acquiescence of Tenant and such appointment
shall remain unvacated or unstayed for an aggregate of sixty (60) days (whether or not consecutive); 
 (vii) If: (x) Tenant shall fail to pay the Basic Rent, Escalation Charges or any other Additional Rent hereunder when due or shall fail to perform or observe any other covenant herein contained on Tenant’s part to be
performed or observed and Tenant shall cure any such failure within the applicable grace period set forth in clauses (i) or (ii) above; or (y) an Event of Default of the kind set forth in clauses (i) or (ii) above
shall occur and Landlord shall, in its sole

  

 -48- 

 
discretion, permit Tenant to cure such Event of Default after the applicable grace period has expired; and the same or a similar failure shall occur more than once within the next 365 days
(whether or not such similar failure is cured within the applicable grace period); or 
 (viii) The occurrence of
any of the events described in paragraphs (a)(iv)-(a)(vi) with respect to any guarantor of all or any portions of Tenant’s obligations under this Lease; 
 then in any such case Landlord may terminate this Lease as hereinafter provided and exercise any other rights or remedies available under this Lease, at law or in equity. 
 (b) For purposes of clause (a)(v) above, an “Event of Bankruptcy” means the filing of a voluntary
petition by Tenant, or the entry of an order for relief against Tenant, under Chapter 7, 11, or 13 of the Bankruptcy Code, and the term “Bankruptcy Code” means 11 U.S.C. §101, et seq.. If an Event of Bankruptcy occurs,
then the trustee of Tenant’s bankruptcy estate or Tenant as debtor-in-possession may (subject to final approval of the court) assume this Lease, and may subsequently assign it, only if it does the following within sixty (60) days after the
date of the filing of the voluntary petition, the entry of the order for relief (or such additional time as a court of competent jurisdiction may grant, for cause, upon a motion made within the original sixty-day period): 
 (i) file a motion to assume the Lease with the appropriate court; 
 (ii) satisfy all of the following conditions, which Landlord and Tenant acknowledge to be commercially reasonable:

 (A) cure all Defaults of Tenant under this Lease or provide Landlord with Adequate Assurance (as defined
below) that it will (x) cure all monetary Defaults of Tenant hereunder within ten (10) days from the date of the assumption; and (y) cure all nonmonetary Defaults of Tenant hereunder within thirty (30) days from the date of the
assumption; 
 (B) compensate Landlord and any other person or entity, or provide Landlord with Adequate
Assurance that within ten (10) days after the date of the assumption, it will compensate Landlord and such other person or entity, for any pecuniary loss that Landlord and such other person or entity incurred as a result of any Event of
Default, the trustee, or the debtor-in-possession; 
 (C) provide Landlord with Adequate Assurance of Future
Performance (as defined below) of all of Tenant’s obligations under this Lease; and 
  

 -49- 

 (D) deliver to Landlord a written statement that the conditions herein have
been satisfied. 
 (c) For purposes only of the foregoing paragraph (b), and in addition to any other
requirements under the Bankruptcy Code, any future federal bankruptcy law and applicable case law, “Adequate Assurance” means at least meeting the following conditions, which Landlord and Tenant acknowledge to be commercially
reasonable: 
 (i) entering an order segregating sufficient cash to pay Landlord and any other person or entity
under paragraph (b) above, and 
 (ii) granting to Landlord a valid first lien and security interest
(in form acceptable to Landlord) in all property comprising the Tenant’s “property of the estate,” as that term is defined in Section 541 of the Bankruptcy Code, located on, used at or relating to the Premises, which lien and
security interest secures the trustee’s or debtor-in-possession’s obligation to cure the monetary and nonmonetary defaults under the Lease within the periods set forth in paragraph (b) above. 
 (d) For purposes only of paragraph (b) above, and in addition to any other requirements under the Bankruptcy
Code, any future federal bankruptcy law and applicable case law, “Adequate Assurance of Future Performance” means at least meeting the following conditions, which Landlord and Tenant acknowledge to be commercially reasonable:

 (i) the trustee or debtor-in-possession depositing with Landlord, as security for the timely payment of rent
and other monetary obligations, an amount equal to the sum of two (2) months’ Basic Rent plus an amount equal to two (2) months’ installments on account of Escalation Charges; 
 (ii) the trustee or the debtor-in-possession agreeing to pay in advance, on each day that the Basic Rent is payable, the
monthly installments on account of Escalation Charges; 
 (iii) the trustee or debtor-in-possession providing
adequate assurance of the source of the rent and other consideration due under this Lease; 
 (iv) Tenant’s
bankruptcy estate and the trustee or debtor-in-possession providing Adequate Assurance of the feasibility of the bankruptcy estate (and any successor after the conclusion of the Tenant’s bankruptcy proceedings) continuing to have sufficient
unencumbered assets after the payment of all secured obligations and administrative expenses to assure Landlord that the bankruptcy estate (and any successor after the conclusion of the Tenant’s bankruptcy proceedings) will have sufficient
funds to fulfill Tenant’s obligations hereunder. 
  

 -50- 

 (e) If the trustee or the debtor-in-possession assumes the Lease under
paragraph (b) above and applicable bankruptcy law, it may assign its interest in this Lease only if the proposed assignee first provides Landlord with Adequate Assurance of Future Performance of all of Tenant’s obligations under the
Lease, and if Landlord determines, in the exercise of its reasonable business judgment, that the assignment of this Lease will not breach any other lease, or any mortgage, financing agreement, or other agreement relating to the Property by which
Landlord or the Property is then bound (and Landlord shall not be required to obtain consents or waivers from any third party required under any lease, mortgage, financing agreement, or other such agreement by which Landlord is then bound).

 (f) For purposes only of paragraph (e) above, and in addition to any other requirements under the
Bankruptcy Code, any future federal bankruptcy law and applicable case law, “Adequate Assurance of Future Performance” means at least the satisfaction of the following conditions, which Landlord and Tenant acknowledge to be commercially
reasonable: 
 (i) the proposed assignee submitting a current financial statement, audited by a certified public
accountant, that allows a net worth and working capital in amounts determined in the reasonable business judgment of Landlord to be sufficient to assure the future performance by the assignee of Tenant’s obligation under this Lease; and

 (ii) if requested by Landlord in the exercise of its reasonable business judgment, the proposed assignee
obtaining a guarantee (in form and substance satisfactory to Landlord) from one or more persons who satisfy Landlord’s standards of creditworthiness. 
 14.2 Landlord’s Remedies. 
 (a) Upon the
occurrence of an Event of Default, Landlord may, in addition to any remedies otherwise available to Landlord, immediately or at any time thereafter, and without demand or notice, enter into and upon the Premises or any part thereof in the name of
the whole and repossess the same as of Landlord’s former estate, and expel Tenant and those claiming by, through or under it and remove its or their effects (forcibly if necessary) without being deemed guilty of any manner of trespass, and
without prejudice to any remedies which might otherwise be used for arrears of rent or preceding breach of covenant, and/or Landlord may terminate this Lease by notice to Tenant, specifying a date not less than five (5) days after the giving of
such notice on which this Lease shall terminate and this Lease shall terminate and come to an end on the date specified therein as fully and completely as if such date were the date herein originally fixed for the expiration of the Term of this
Lease, and Tenant will then quit and surrender the Premises to Landlord, but Tenant shall remain liable as hereinafter provided. To the extent permitted by law, Tenant hereby expressly waives any and all rights of redemption granted by or under any
present or future laws (including M.G.L. c.186, §11), in the event of Tenant being evicted or dispossessed, or in the event of

  

 -51- 

 
Landlord obtaining possession of the Premises, by reason of the violation by Tenant of any of the covenants and conditions of this Lease. In the event of any such termination, entry or re-entry,
Landlord shall have the right to remove and store Tenant’s property and that of persons claiming by, through or under Tenant at the sole risk and expense of Tenant and, if Landlord so elects, (x) to sell such property at public auction or
private sale and apply the net proceeds to the payment of all sums due to Landlord from Tenant and pay the balance, if any, to Tenant, or (y) to dispose of such property in any manner in which Landlord shall elect, Tenant hereby agreeing to the
fullest extent permitted by law that it shall have no right, title or interest in any property remaining in the Premises after such termination, entry or re-entry. 
 (b) If this Lease shall have been terminated as provided in this Article, or if any execution or attachment shall be
issued against Tenant or any of Tenant’s property whereupon the Premises shall be taken or occupied by someone other than Tenant, then Landlord may re-enter the Premises, either by summary proceedings, ejectment or otherwise, and remove and
dispossess Tenant and all other persons and any and all property from the same, as if this Lease had not been made. 
 (c) If Landlord enters or re-enters the Premises as aforesaid and/or this Lease shall have been terminated as provided in this Article, Tenant shall pay the Basic Rent, Escalation Charges, Additional Rent and other sums payable hereunder up
to the time of such termination, and thereafter Tenant, until the end of what would have been the Term of this Lease in the absence of such entry/re-entry or termination, and whether or not the Premises shall have been relet, shall be liable to
Landlord for, and shall pay to Landlord, as liquidated current damages, the Basic Rent, Escalation Charges, Additional Rent and other sums that would be payable hereunder if such termination had not occurred, less the net proceeds, if any, received
by Landlord in reletting the Premises, after deducting all expenses in connection with such reletting, including, without limitation, all repossession costs, brokerage commissions, legal expenses, attorneys’ fees, advertising, expenses of
employees, alteration costs and expenses of preparation for such reletting. Tenant shall pay the portion of such current damages referred to above to Landlord monthly on the days which the Basic Rent would have been payable hereunder if this Lease
had not been terminated, and Tenant shall pay the portion of such current damages referred to in clause (y) above to Landlord upon such termination. 
 (d) As an alternative, at the election of the Landlord at any time after termination of this Lease as provided in this Article, whether or not Landlord shall have collected any such current damages, as
liquidated final damages and in lieu of all such current damages beyond the date of such demand, at Landlord’s election Tenant shall pay to Landlord an amount equal to the excess, if any, of the Basic Rent, Escalation Charges, Additional Rent
and other sums as hereinbefore provided which would be payable hereunder from the date of such demand assuming that, for the purposes of this paragraph, annual payments by Tenant on account of Taxes and Operating Expenses would be the same as the
payments required for the immediately preceding Operating or Tax Year for what would be the then unexpired Term of this Lease if the same remained in effect, over the then fair net rental value of the Premises for the same period, both

  

 -52- 

 
amounts being discounted to present value at an interest rate equal to 200 basis points less than the then-applicable Base Rate (as hereinafter defined). The “Base Rate” shall mean the
prime rate, as set forth in the Wall Street Journal from time to time. 
 (e) In case of any Event of Default,
re-entry, expiration and dispossession by summary proceedings or otherwise, Landlord may (i) re-let the Premises or any part or parts thereof, either in the name of Landlord or otherwise, for a term or terms which may at Landlord’s option
be equal to or less than or exceed the period which would otherwise have constituted the balance of the Term of this Lease and may grant concessions or free rent to the extent that Landlord considers advisable and necessary to re-let the same, and
(ii) make such alterations, repairs and decorations in the Premises as Landlord considers advisable and necessary for the purpose of reletting the Premises, and the making of such alterations, repairs and decorations shall not operate or be
construed to release Tenant from liability hereunder as aforesaid. Tenant hereby expressly waives any and all rights of redemption granted by or under any present or future laws in the event of Tenant being evicted or dispossessed, or in the event
of Landlord obtaining possession of the Premises, by reason of the violation by Tenant of any of the covenants and conditions of this Lease. 
 14.3 Additional Rent. If Tenant shall fail to pay when due any sums under this Lease designated as an Escalation Charge or other Additional Rent, Landlord shall have the same rights and
remedies as Landlord has hereunder for failure to pay Basic Rent. 
 14.4 Remedying Defaults. Landlord shall have
the right, but shall not be required, to pay such sums or do any act which requires the expenditure of monies which may be necessary or appropriate by reason of the failure or neglect of Tenant to perform any of the provisions of this Lease, and in
the event of the exercise of such right by Landlord, Tenant agrees to pay to Landlord forthwith upon demand all such sums, together with interest thereon at a rate equal to 1% over the Base Rate, as Additional Rent. Any payment of Basic Rent,
Escalation Charges, Additional Rent or other sums payable hereunder not paid when due shall, at the option of Landlord, bear interest at a rate equal to 200 basis points over the Base Rate in effect from time to time from the due date thereof and
shall be payable forthwith on demand by Landlord, as Additional Rent. 
 14.5 Remedies Cumulative. The specified
remedies to which Landlord may resort hereunder are not intended to be exclusive of any remedies or means of redress to which Landlord may at any time be entitled lawfully, and Landlord may invoke any remedy (including the remedy of specific
performance) allowed at law or in equity as if specific remedies were not herein provided for. 
 14.6 Enforcement
Costs. In any action or proceeding brought by either party against the other under this Lease, the prevailing party shall be entitled to recover from the other party its reasonable professional fees for attorneys, appraisers and accountants,
its reasonable investigation costs, and any other reasonable legal expenses and actual court costs incurred by the prevailing party in such action or proceeding. 
  

 -53- 

 14.7 Waiver. 
 (a) 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 the other’s 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. 
 (b) 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 of the earliest installment of any payment due from Tenant under the provisions hereof. 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. 
 14.8 [Intentionally Deleted]. 
 14.9 Landlord’s Default. Landlord shall in no event be in default in the performance of any of Landlord’s obligations under this Lease unless Landlord shall have failed to perform
such obligations within thirty (30) days (or such additional time as is reasonably required to correct any such default) after notice by Tenant to Landlord properly specifying wherein Landlord has failed to perform any such obligation. Without
limitation, in no event shall Tenant have the right to terminate or cancel this Lease or to withhold Rent or to set-off or deduct any claim or damages against Rent as a result of any default by Landlord or breach by Landlord of its covenants or any
warranties or promises hereunder, except in the case of a wrongful eviction of Tenant from the Premises (constructive or actual) by Landlord continuing after notice to Landlord thereof and a reasonable opportunity for Landlord to cure the same as
set forth above. In addition, the Tenant shall not assert any right to deduct the cost of repairs or any monetary claim against the Landlord from Rent thereafter due and payable under this Lease, but shall look solely to the interests of the
Landlord in the Property for satisfaction of any such claim. This Lease shall be construed as though Landlord’s covenants contained herein are independent and not dependent, and Tenant hereby waives the benefit of any law or statute to the
contrary. 
 ARTICLE 15 
 MISCELLANEOUS PROVISIONS 
 15.1 Rights of Access.
Landlord, its agents, contractors and employees shall have the right to enter the Premises at all reasonable hours for the purpose of inspecting the Premises, doing maintenance or making repairs or otherwise exercising its rights or fulfilling its
obligations

  

 -54- 

 
under this Lease, and Landlord also shall have the right to make access available at all reasonable hours to prospective or existing mortgagees, purchasers or tenants of any part of the Property.
In connection with the exercise of the foregoing rights or other rights of access afforded by this Lease (excepting routine access such as access for providing cleaning or other regularly scheduled services) Landlord shall exercise reasonable
efforts to minimize any interference with the usual and customary security systems and other operations of the Tenant in the Premises in accordance with the provisions of this Lease and, except in the case of emergency, to provide reasonable advance
notice of any such entry. 
 15.2 Covenant of Quiet Enjoyment. Subject to the terms and conditions of this Lease,
on payment of the Basic Rent and Escalation Charges and other Additional Rent and observing, keeping and performing all of the other terms and conditions of this Lease on Tenant’s part to be observed, kept and performed, Tenant shall lawfully,
peaceably and quietly enjoy the Premises during the term hereof, without hindrance or ejection by Landlord or by any persons lawfully claiming under Landlord to have title to the Premises superior to Tenant. The foregoing covenant of quiet enjoyment
is in lieu of any other covenant, express or implied. 
 15.3 Landlord’s Liability. 
 (a) Tenant agrees to look solely to Landlord’s equity interest in the Property at the time of recovery for recovery of
any judgment against Landlord, and agrees that neither Landlord nor any successor of Landlord shall be personally liable for any such judgment, or for the payment of any monetary obligation to Tenant. The provision contained in the foregoing
sentence is not intended to, and shall not, limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord or any successor of Landlord, or to take any action not involving the personal liability of Landlord or any
successor of Landlord to respond in monetary damages from Landlord’s assets other than Landlord’s equity interest in the Property and the rents and profits directly and proximately resulting therefrom. The covenants of Landlord contained
in this Lease shall be binding upon Landlord and Landlord’s successors only with respect to obligations arising during Landlord and Landlord’s successor’s respective periods of ownership of the Property. 
 (b) Except as expressly and specifically set forth in Articles 10 and 12 hereof, in no event shall either party
ever be liable to the other for any loss of business or any other indirect or consequential damages suffered by such party from whatever cause. 
 (c) Where provision is made in this Lease for Landlord’s consent, and Tenant shall request such consent, and Landlord shall fail or refuse to give such consent, Tenant shall not be entitled to any
damages for any withholding by Landlord of its consent, it being intended that Tenant’s sole remedy shall be an action for specific performance or injunction, and that such remedy shall be available only in those cases where Landlord has
expressly agreed in writing not to unreasonably withhold its consent. Furthermore, whenever Tenant requests Landlord’s consent or approval (whether or not provided for herein), Tenant shall pay to Landlord, on demand, as Additional Rent, any
reasonable expenses incurred by Landlord (including without limitation reasonable attorneys’ fees and costs, if any) in connection therewith. 
  

 -55- 

 (d) Any repairs or restoration required or permitted to be made by Landlord
under this Lease may be made during normal business hours, and Landlord shall have no liability for damages to Tenant for inconvenience, annoyance or interruption of business arising therefrom. 
 (e) The Landlord shall in no event be liable for failure to perform any of its obligations under this Lease when prevented
from doing so by causes beyond its reasonable control, including, without limitation, Force Majeure events, labor dispute, breakdown, accident, order or regulation of or by any governmental authority, or failure of supply, or inability by the
exercise of reasonable diligence to obtain supplies, parts, or employees necessary to furnish services required under this Lease, or because of war or other emergency, or for any cause due to any act, neglect, or default of Tenant or Tenant’s
servants, contractors, agents, employees, licensees or any person claiming by, through or under Tenant. 
 15.4 Estoppel
Certificates. 
 (a) Within ten (10) Business Days following request from Landlord or any
Holder, Tenant shall deliver to Landlord a statement executed and acknowledged by Tenant, in form reasonably satisfactory to Landlord, (a) stating the Commencement Date, the Rent Commencement Date, and the Expiration Date, and that this Lease
is then in full force and effect and has not been modified (or if modified, setting forth all modifications), (b) setting forth the date to which the Basic Rent and any Additional Rent have been paid, together with the amount of monthly Basic
Rent and Additional, Rent then payable, (c) stating whether or not, to the best of Tenant’s knowledge, Landlord is in default under this Lease, and, if Landlord is in default, setting forth the specific nature of all such defaults,
(d) stating the amount of the security, if any, under this Lease, (e) stating whether there are any subleases or assignments affecting the Premises, (f) stating the address of Tenant to which all notices and communications under the
Lease shall be sent, and (g) responding to any other matters reasonably requested by Landlord or such Holder. Tenant acknowledges that any statement delivered pursuant to this Section 15.4 may be relied upon by any purchaser or
owner of the Property or the Building, or all or any portion of Landlord’s interest in the Property or the Building or by any Holder, or assignee thereof. 
 (b) From time to time, but not more than two times within any 12 month period, within ten (10) Business Days following
request from Tenant, Landlord shall deliver to Tenant a statement executed by Landlord certifying (i) that this Lease is then in full force and effect and has not been modified (or if modified, setting forth all such modifications),
(ii) setting forth the date to which Basic Rent and any Additional Rent have been paid, together with the amount of monthly Basic Rent, and Escalation Rent then payable by Tenant under this Lease, (iii) stating whether or not, to the best
knowledge of Landlord, but without independent investigation, Tenant is then in default

  

 -56- 

 
under this Lease if so, setting forth the specific nature of all such defaults, and (iv) responding to such other matters concerning this Lease as may be reasonably requested by Tenant.

 15.5 Brokerage. Tenant warrants and represents that Tenant has dealt with no broker in connection with the
consummation of this Lease other than the Brokers, and, in the event of any brokerage claims against Landlord predicated upon prior dealings with Tenant, Tenant agrees to defend the same and indemnify Landlord against any such claim (except any
claim by the Brokers). Landlord warrants and represents that it has not dealt directly or indirectly, in connection with the leasing of the Demised Premises, with any broker, agent, or other person entitled to claim a commission or fee therefor
other than the Brokers, and in the event of any brokerage claims against the Tenant predicated upon prior dealings with the Landlord named herein, Landlord agrees to defend the same and indemnify Tenant against any such claim. Landlord shall be
responsible for payment of brokerage commissions to the Brokers pursuant to a separate agreement. 
 15.6 Financial
Statements. Tenant shall, at any time and from time to time, upon not less than ten (10) Business Days’ prior written notice by Landlord, deliver to Landlord Tenant’s most recently audited, or if not available unaudited,
financial statements, in form reasonably satisfactory to Landlord. 
 15.7 [Intentionally Deleted]. 
 15.8 Rules and Regulations. Tenant shall abide by the Rules and Regulations from time to time established by Landlord, it
being agreed that such Rules and Regulations will be established and applied by Landlord in a non-discriminatory fashion, such that all Rules and Regulations shall be generally applicable to other tenants of the Building of similar nature to the
Tenant named herein. Landlord agrees to use reasonable efforts to insure that any such Rules and Regulations are uniformly enforced, but Landlord shall not be liable to Tenant for violation of the same by any other tenant or occupant of the
Building, or persons having business with them. In the event that there shall be a conflict between such Rules and Regulations and the provisions of this Lease, the provisions of this Lease shall control. The Rules and Regulations currently in
effect are set forth in Exhibit E. 
 15.9 Invalidity of Particular Provisions. 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. 
 15.10 Provisions Binding, Etc. 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 (except in the case of Tenant, only such successors and assigns as may be permitted hereunder) and, if Tenant shall be an individual, upon and to his heirs, executors,
administrators, successors and permitted assigns. Each term and each provision of this Lease to

  

 -57- 

 
be performed by Tenant shall be construed to be both a covenant and a condition. Any reference in this Lease to successors and assigns of Tenant shall not be construed to constitute a consent to
assignment by Tenant. 
 15.11 Recording. Tenant agrees not to record this Lease, but, if the Term of this Lease
(including any extended term) is seven (7) years or longer, each party hereto agrees, on the request of the other, to execute a notice of lease in recordable form and complying with applicable law. In no event shall such document set forth the
rent or other charges payable by Tenant under this Lease; and any such document shall expressly state that it is executed pursuant to the provisions contained in this Lease, and is not intended to vary the terms and conditions of this Lease. At
Landlord’s request, promptly upon expiration of or earlier termination of the Term, Tenant shall execute and deliver to Landlord a release of any document recorded in the real property records for the location of the Property evidencing this
Lease, and Tenant hereby appoints Landlord Tenant’s attorney-in-fact, coupled with an interest, to execute any such document if Tenant fails to respond to Landlord’s request to do so within fifteen (15) days. The obligations of Tenant
under this Section shall survive the expiration or any earlier termination of the Term. 
 15.12 Notice. All
notices or other communications required hereunder shall be in writing and shall be deemed duly given if delivered in person (with receipt therefor), if sent by reputable overnight delivery or courier service (e.g., Federal Express) providing for
receipted delivery, or if sent by certified or registered mail, return receipt requested, postage prepaid, to the following address:

other communication shall be conclusively established by either (i) return of a return receipt indicating that the notice has been delivered; or (ii) return of the letter containing the notice with an indication from the courier or postal
service that the addressee has refused to accept delivery of the notice. Either party may change its address for the giving of notices by notice given in accordance with this Section. 
 15.13 When Lease Becomes Binding; Entire Agreement; Modification. 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. This Lease is the
entire agreement between Landlord and Tenant, and this Lease expressly supersedes any negotiations, considerations, representations and understandings and proposals or other

  

 -58- 

 
written documents relating hereto. This Lease 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. 
 15.14 Paragraph Headings and Interpretation of Sections.
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. The provisions of this Lease shall be construed as a whole, according to their common meaning (except where a precise legal interpretation is clearly evidenced), and not for or against either party. Use in this Lease of the words
“including,” “such as” or words of similar import, when followed by any general term, statement or matter, shall not be construed to limit such term, statement or matter to the specified item(s), whether or not language of
non-limitation, such as “without limitation” or “including, but not limited to,” or words of similar import, are used with reference thereto, but rather shall be deemed to refer to all other terms or matters that could fall
within a reasonably broad scope of such term, statement or matter. 
 15.15 Dispute Resolution. In the event of a
dispute between Landlord and Tenant pursuant to this Lease (other than a dispute relating to the payment of Basic Rent and Escalation Charges) the parties agree that prior to pursuing other available remedies (excluding giving notices of default),
they will attempt to directly negotiate resolution of their dispute. If negotiation is unsuccessful, then they agree to participate in at least three hours of non-binding mediation to be facilitated by a mediator mutually acceptable to them under
the mediation procedures set by the mediator. The non-binding mediation session shall be conducted within thirty (30) days of the date on which the mediator receives the request to mediate. The costs of such mediation shall be shared equally by
the parties. 
 15.16 Waiver of Jury Trial. Landlord and Tenant hereby each waive trial by jury in any action,
proceeding or counterclaim brought by either against the other, on or in respect of any matter whatsoever arising out of or in any way connected with this Lease, the relationship of Landlord and Tenant or Tenant’s use or occupancy of the
Premises. 
 15.17 Time Is of the Essence. Time is of the essence of each provision of this Lease. 
 15.18 Multiple Counterparts. This Lease may be executed in multiple counterparts, each of which shall be deemed an original
and all of which together shall constitute one and the same document. 
 15.19 Governing Law. This Lease shall be
governed by the laws of the Commonwealth of Massachusetts without regard to conflicts of laws. 
 15.20 Building Name,
Property Name, Exterior Signage. Landlord may elect at any time to change the name(s), number(s) or designation(s) by which the Buildings and/or the Property is (or are) commonly known; provided, however, (i) Landlord will not name
either Building and/or the Property for any other tenant thereof, and (ii) if Landlord elects to change the number(s) by which the Buildings and/or the Property is (or are) commonly known, Landlord

  

 -59- 

 
shall provide not less than six (6) months prior notice thereof to Tenant. Landlord may elect, from time to time, to install exterior signage on the Buildings; provided, however, any such
signage which identifies other tenants of the Buildings shall be less prominent than the signage installed by or on behalf of Tenant and shall be reasonably tasteful and restrained in all respects. 
 ARTICLE 16 
 PARKING 
 16.1 Parking Spaces. During the Term, upon the request of Tenant, Tenant shall
be entitled to contract for use by Tenant’s employees of up to eighteen (18) parking spaces in the Post Office Square Parking Garage (the “Garage”). In addition, if Tenant exercises its rights pursuant to Articles 17 and
23 of this Lease and adds additional space to the Premises leased hereunder and to the extent additional parking spaces are then-available in the Garage, Tenant may contract for use by Tenant’s employees of one (1) additional
parking space for each 5,440 square feet of rentable area of such additional space (excluding any storage areas); provided, however, in no event shall Tenant be entitled to contract for more than twenty-eight (28) parking spaces in the
aggregate. The monthly rent per parking space from time to time shall be equal to the prevailing rate charged from time to time by the Garage operator, as the case may be; provided, however, said rate shall not exceed the then-applicable lowest
monthly rate per parking space then provided to other tenants of the Property. 
 16.2 Responsibility for Garage.
Tenant acknowledges that the Garage is not owned or controlled by Landlord, and that while Landlord has an agreement with the owner of the Garage concerning the provision of parking spaces to tenants at the Buildings, Landlord has no control over
the owner and the operator of the Garage. The management and operation of the Garage shall be solely the responsibility of the Garage owner and operator and Landlord shall have no liabilities or obligations, of any kind, with respect thereto. Tenant
hereby waives and releases any claims, actions, causes of action or the like against Landlord arising out of or relating to the Garage and/or the use thereof by Tenant’s employees. Landlord does not assume any responsibility for, and shall not
be held liable for, any damage or loss to any automobiles parked in the Garage or to any personal property located therein, or for any injury sustained by any person in or about the Garage. Any failure or inability to provide any such parking
spaces, whether because of casualty, eminent domain or for any other reason beyond Landlord’s control, shall not constitute a breach of any of Landlord’s obligations under this Lease and shall in no event entitle Tenant to terminate this
Lease or to any compensation, damages or other claim against Landlord. Tenant and its employees shall at all times comply with all rules and regulations promulgated by the Garage operator, including requirements concerning identification or parking
stickers. 
 16.3 Personal Rights. The rights granted to Tenant in this Article 16 are personal to Boston
Private Financial Holdings, Inc. and the Affiliates thereof, and may not be assigned or transferred to or exercisable by any other persons or entities. 
  

 -60- 

 ARTICLE 17 
 RIGHT OF FIRST OFFER TO LEASE SPACE 
 17.1 ROFO Rights. If at any time prior to the ninth (9th
) anniversary of the Commencement Date, Landlord in its sole discretion determines that any separately demised rentable area on any floor of either Building (each such area, a “ROFO
Space”) other than the Excluded Areas (as hereinafter defined) has become “available for leasing” (as hereinafter defined), and provided that the conditions precedent set forth in Section 17.3 below are then satisfied,
then prior to offering to lease such ROFO Space to any 3rd
parties, Landlord shall deliver notice thereof to Tenant (the “ROFO Notice”) setting forth a description of the ROFO Space in question (including the rentable area thereof), the Landlord’s determination of the fair market rental value
(as defined in Section 4.4), for such ROFO Space, the other material business terms upon which Landlord is willing to lease the ROFO Space, and the date Landlord anticipates that the ROFO Space will become available for leasing. Provided
that all of the conditions precedent set forth in this Article 17 are fully satisfied by Tenant, Tenant shall have the option (the “ROFO Option”), exercisable by Tenant delivering written notice (the “Acceptance Notice”)
to Landlord within twenty (20) calendar days after delivery by Landlord of the ROFO Notice, to lease the ROFO Space upon all of the terms and conditions set forth in the ROFO Notice, including the Basic Rent, Escalation Rent, and Additional
Rent for the ROFO Space designated by Landlord as set forth therein. Time shall be of the essence as to Tenant’s giving of the Acceptance Notice with respect to any ROFO Space. 
 If (a) Tenant fails to deliver an Acceptance Notice within such twenty (20) day period, or (b) if Tenant
timely delivers an Acceptance Notice as aforesaid but does not execute and deliver a final fully executed amendment to this Lease with respect to the leasing of the ROFO Space, in form and substance reasonably satisfactory to Landlord, within thirty
(30) days after delivery by Landlord of the proposed lease amendment to Tenant, then Tenant shall be deemed to have rejected the option to lease the applicable ROFO Space (the “Rejected ROFO Space”). In such event, except as set forth
in this paragraph, Tenant shall have no further rights or claims with respect to the Rejected ROFO Space, Landlord shall have no further liabilities or obligations to Tenant with respect to the Rejected ROFO Space, and Landlord may elect to lease
the Rejected ROFO Space to 3rd parties upon such terms and
conditions as Landlord may determine in its discretion. Notwithstanding the foregoing, if (i) Tenant was entitled to exercise its ROFO Option but failed to deliver an Acceptance Notice within the twenty (20) day period set forth above, and
(ii) Landlord does not enter into a lease for the respective ROFO Space within a period of twelve (12) months following the date of the ROFO Notice, then Tenant’s rights shall be revived and Tenant shall once again have a ROFO Option
with respect to the respective ROFO Space. In addition, notwithstanding the foregoing, if any Rejected ROFO Space shall be leased to any third party and, after the expiration or termination of said lease (including any extensions or renewals which
may, from time to time, be granted to the Tenant pursuant to said lease), such Rejected ROFO Space again becomes available for leasing prior to the expiration or earlier termination of the Term of this Lease or the expiration of the ROFO Rights of
Tenant pursuant to Section 17.6, then Tenant’s right of first offer under this Article 17 with respect to such Reject ROFO Space shall again become effective, in accordance with and subject to all of the terms and conditions thereof.

  

 -61- 

 Notwithstanding the foregoing, if Tenant, in its good faith reasonable judgment, determines
that the rate set forth in Landlord’s ROFO Notice does not accurately reflect the fair market rental value for the respective ROFO Space, Tenant may elect to exercise the ROFO Option and provide Landlord with an Acceptance Notice which
expressly and specifically states that Tenant objects to the Landlord’s determination of the fair market rental value for the respective ROFO Space. Such exercise of the ROFO Option shall be unconditional and irrevocable, subject only to the
determination of the fair market rental value for the respective ROFO Space. In such event, for a period of fifteen (15) days after the delivery of Tenant’s Acceptance Notice, Landlord and Tenant shall work together in good faith to
determine the fair market rental value for the ROFO Space. If Landlord and Tenant fail to agree upon the fair market rental value for the respective ROFO Space within such fifteen (15) day period, then the fair market rental value shall be
determined in accordance with the arbitration procedure described in Sections 4.4(b), 4.4(c), and 4.4(d) of this Lease. If Tenant fails to provide an Acceptance Notice which expressly and specifically state that Tenant objects
to Landlord’s determination of fair market rental value for the respective ROFO Space, then Tenant shall be deemed to have accepted Landlord’s determination. 
 17.2 Excluded Areas, Available for Leasing, Exclusions, etc.. For purposes of this Article 17, the
“Excluded Areas” shall mean the following: (i) any areas on the basement level of either Building; (ii) an area on the 12th Floor of the Ten P.O. Square Building comprising approximately 3,434 rentable square feet, which area is depicted on
the plan attached hereto as Exhibit F-1; and (iii) an area on the 8th Floor of the Ten P.O. Square Building comprising approximately 3,434 rentable square feet, which area is depicted on the plan attached hereto as Exhibit F-2. For purposes of this Article
17, space shall be deemed “available for leasing” when Landlord has determined in its discretion that (a) the space is vacant, or (b) the respective existing tenant or occupant will not extend or renew the term of its
lease or other occupancy agreement for the ROFO Space and that said existing tenant or occupant is not interested either in extending or renewing its lease or other occupancy agreement for the ROFO Space or in entering into a new lease for such ROFO
Space. For purposes of this Article 17, space shall not be deemed “available for leasing” if, at the time in question (a) any person or entity leases or occupies the ROFO Space, whether pursuant to a lease or other
agreement (unless such person or entity confirms to the satisfaction of Landlord that it does not intend to extend or renew the term of the lease or other occupancy agreement for the ROFO space or enter into a new lease for such ROFO Space),
(b) any person or entity holds any option or right to lease or occupy the ROFO Space, or to renew its lease or right(s) of occupancy thereof, or any other rights or claims thereto (including, without limitation, any rights of first offer,
rights of first refusal or expansion rights), or (c) Landlord intends occupy the ROFO Space, or to lease or otherwise permit the occupancy of the ROFO Space by an affiliate or subsidiary of Landlord. Without limitation, so long as a tenant or
other occupant leases or occupies all or a portion of the ROFO Space, Landlord shall be free to extend or renew any such tenancy or occupancy, whether or not pursuant to a lease or other agreement, and such space shall not be deemed to be
“available for leasing.” In no event shall Landlord be liable to Tenant for any failure by any then existing tenant or occupant to vacate any ROFO Space by any particular date. Nothing set forth in this Article 17 shall be construed
to limit Landlord’s right to lease space in the Buildings to affiliates of Landlord, or to keep space in the Buildings vacant if Landlord elects, in its sole discretion, to do so, and such space leased to affiliates, subsidiaries or related
entities, or vacant space, shall in no event be

  

 -62- 

 
deemed to be “available for leasing” hereunder. Notwithstanding anything herein to the contrary, all rights of first offer granted to Tenant pursuant to this Article 17 are
subject and subordinate in all respects to the rights (whether such rights are designated as a right of first offer, right of first refusal, expansion option or otherwise) of any tenant or occupant of the Building(s) existing on the date of this
Lease. 
 17.3 Conditions. Tenant shall have no right to exercise any ROFO Option unless all of the following
conditions have been satisfied both on the date of the Acceptance Notice and on the ROFO Space Commencement Date (as hereinafter defined): (a) No uncured default or Event of Default shall exist under this Lease; and (b) Boston Private
Financial Holdings, Inc. and/or Affiliates of Boston Private Financial Holdings, Inc. is (or are) occupying not less than sixty-five percent (65%) of the rentable area of the Premises then demised under this Lease. 
 17.4 Terms. Effective as of the date on which Landlord delivers the ROFO Space to Tenant (the “ROFO Space Commencement
Date”): 
 (i) The ROFO Space shall be added to and be deemed to be a part of the Premises for all purposes
under this Lease (except as otherwise provided in this Article 17); 
 (ii) The ROFO Space shall be
delivered in broom-clean condition, free of all tenants and occupants and otherwise in its “as is” condition; Landlord shall not be obligated to perform any work or improvements or to provide any allowances or inducements with respect
thereto; 
 (iii) Basic Rent, Escalation Rent and Additional Rent for the ROFO Space shall be as set forth in the
ROFO Notice; and 
 (iv) Tenant shall pay all Additional Rent payable under this Lease with respect to the
applicable ROFO Space, except to the extent that any such Additional Rent is included in the amounts payable under clause (iii) above. 
 17.5 Amendment. If Tenant exercises the ROFO Option, upon request made by Landlord, Tenant will execute, acknowledge and deliver to Landlord an amendment to this Lease confirming the ROFO
Space Commencement Date, the Basic Rent, Escalation Rent and Additional Rent payable with respect to the ROFO Space, the incorporation of the ROFO Space into the Premises, and the modifications to this Lease resulting therefrom, as provided in
subsection 17(d). The failure of either party to execute and deliver such an amendment shall not affect the rights, liabilities or obligations of the parties with respect to the ROFO Space. 
 17.6 Expiration. Notwithstanding any provision contained herein to the contrary, if and when the date which is twenty-four
(24) months prior to then-scheduled expiration date of the Term of this Lease occurs (as such expiration date may be extended from time to time pursuant to Section 4.4 of this Lease), then this Article 17 shall become null and
void and of no further force or effect and Tenant shall have no further ROFO Options or other rights to lease any ROFO Space pursuant to this Article 17. In such event, all of the obligations of Landlord to

  

 -63- 

 
offer any ROFO Space to Tenant shall be considered to have been fully and completely satisfied, and neither Landlord nor Tenant shall have any further rights, liabilities or obligations under
this Article 17. 
 ARTICLE 18 
 ROOFTOP EQUIPMENT 
 18.1 Rooftop Equipment. Subject to
approval by all applicable governmental authorities and the provisions of this Article 18, so long as (i) this Lease is in full force and effect, (ii) no Event of Default shall have occurred, and (iii) at the time of the
request submitted by Tenant there is space available on the roof of the Ten P.O. Square Building/10 P.O. Square Building, then Tenant shall have the right, at Tenant’s sole cost and expense, to install, use, maintain and operate on the roof of
such Building one satellite dish or similar antennae and related equipment and/or an electrical generator (collectively, the “Roof Equipment”). The Roof Equipment shall be of a size and located in an area of the roof
acceptable to Landlord in its reasonable discretion. The installation, use, maintenance, repair, operation and removal of the Roof Equipment shall at all times comply with all applicable legal requirements, and with all of the following terms and
conditions: 
  

	 	(1)	If and so long as the Roof Equipment is used solely by Tenant for the operation of its business at the Property, then, except as set forth in this Article 18,
there shall be no additional rent payable to Landlord in connection therewith; however, if and to the extent Tenant receives any direct revenues from third parties arising out of resulting from such Roof Equipment, including, without limitation,
license fees, transmission fees or other types of fees, then Tenant shall pay all such third party revenues over to Landlord, as Additional Rent, without deduction or set-off of any kind. 

  

	 	(2)	Tenant shall be solely and exclusively responsible for all costs, expenses and charges, of every kind, of installing, operating, maintaining, repairing, replacing, and
removing the Roof Equipment and Landlord shall have no liability or obligation in connection therewith. 

  

	 	(3)	 If, in the judgment of Landlord, any electrical, electromagnetic, radio frequency or other interference shall result from the operation of any of the
Roof Equipment, Tenant agrees that Landlord may, at Landlord’s option, shut down Tenant’s Roof Equipment upon 4 hours prior notice to Tenant; provided, however, if an emergency situation exists, which Landlord reasonably determines in its
discretion to be attributable to the Roof Equipment, Landlord shall immediately notify Tenant orally, who shall act immediately to remedy the emergency situation. Should Tenant fail to so remedy said emergency situation, Landlord may then act to
shut down Tenant’s Roof Equipment. Tenant shall indemnify Landlord and hold it harmless from, and Tenant waives, all expenses, costs, damages, losses, claims or other liabilities arising out of said shutdown. Tenant

  

 -64- 

	 	 
agrees to cease operations (except for intermittent testing on a schedule approved by Landlord) until the interference has been corrected to the reasonable satisfaction of Landlord. If such
interference has not been corrected to the satisfaction of Landlord within 30 days, Landlord may require that Tenant immediately remove from the Roof Space the specific item of equipment causing such interference, in which latter case the Additional
Rent payable on account of the Roof Equipment shall be equitably reduced. 

  

	 	(4)	Tenant shall, at its sole cost and expense, and at its sole risk, install, operate and maintain the Roof Equipment in a good and workmanlike manner, and in compliance
with all electric, communication, and safety codes, ordinances, standards, regulations and requirements, now in effect or hereafter promulgated, of the Federal Government, including, without limitation, the Federal Communications Commission (the
“FCC”), the Federal Aviation Administration (“FAA”) or any successor agency of either the FCC or FAA having jurisdiction over radio or telecommunications, and of the state, city and county in which the
Building is located. Tenant shall cooperate generally with Landlord and other carriers to permit the Building’s rooftop to be and remain in compliance with all FCC and OSHA rules and regulations relating to radio frequency emission levels and
maximum permissible exposure, including but not limited to the rules and regulations adopted in FCC document OET 65 (which rules and regulations have also been adopted by OSHA). Neither Landlord nor its agents shall be liable to Tenant for any
stoppages or shortages of electrical power furnished to the Roof Equipment or the roof area because of any act, omission or requirement of the public utility serving the Building, or the act or omission of any other tenant, invitee or licensee or
their respective agents, employees or contractors, or for any other cause beyond the reasonable control of Landlord, and Tenant shall not be entitled to any rental abatement for any such stoppage or shortage of electrical power. Neither Landlord nor
its agents shall have any responsibility or liability for the conduct or safety of any of Tenant’s representatives, repair, maintenance and engineering personnel while in or on any part of the Building or the roof area.

  

	 	(5)	Landlord shall have no obligation to provide any electricity or other utilities or services to the Roof Equipment. Tenant shall be responsible for connecting the Roof
Equipment to the electrical outlets currently located on the roof, and for the costs and expenses of all electricity consumed in connection with the Roof Equipment. 

  

	 	(6)	Tenant shall not make any changes, alterations, or other improvements on or to the roof of such Building without Landlord’s prior written consent in each instance,
which consent, Landlord may withhold at its discretion; provided, however, in connection with the installation, operation, maintenance, repair or replacement of the Roof Equipment, Landlord’s consent shall not be unreasonably withheld.

  

 -65- 

	 	(7)	Tenant shall have no right of access to the roof of such Building unless Tenant has given Landlord reasonable advance notice and unless Tenant’s representatives
are accompanied by a representative of Landlord. 

  

	 	(8)	Tenant shall indemnify and hold Landlord harmless from (i) any liability, cost or expense incurred by Landlord arising out of or resulting from the erection,
installation, maintenance, operation and removal of the Roof Equipment, and (ii) any and all claims, costs, damages and expenses (including reasonable attorneys’ fees) arising out of accidents, damage, injury or loss to any and all persons
and property resulting from or arising in connection with the erection, installation, maintenance, operation and removal of the Roof Equipment; 

  

	 	(9)	Tenant shall promptly repair any damage caused by reason of such installation, use, maintenance, operation and removal of the Roof Equipment, including, without
limitation, any repairs, restorations, maintenance, renewals or replacements of the roof (or portion thereof) necessitated by or in any way caused by or relating to such installations or the operation or presence of the Roof Equipment on the roof;

  

	 	(10)	Tenant shall remove the Roof Equipment and repair any resulting damage to such Building (including, without limitation, restoration of the roof to the condition which
existed prior to any such installation, damage by casualty and ordinary wear and tear excepted) not less than thirty (30) days prior to the expiration or earlier termination of the Term; 

  

	 	(11)	Prior to installation, Tenant shall submit to Landlord for Landlord’s approval, in its sole discretion, plans and specifications for the Roof Equipment (including,
without limitation, the size of the Roof Equipment). The installation, operation, maintenance, repair and removal of the Roof Equipment shall be performed by a contractor or contractors retained by Tenant, at its sole cost and expense, and approved
in each instance by Landlord. Tenant shall be responsible for obtaining any permits and licenses required for the installation and operation of the Roof Equipment and Landlord agrees to cooperate with Tenant to accomplish the same, provided that
Tenant shall promptly reimburse Landlord for Landlord’s reasonable costs and expenses in connection with such cooperation; 

  

	 	(12)	Tenant’s Roof Equipment shall be for the sole use of Tenant and may be used only in connection with Tenant’s business within the Premises;

  

 -66- 

	 	(13)	Tenant shall keep the Roof Equipment in good order and condition, at Tenant’s sole cost and expense, and shall promptly make any necessary repairs thereto;

  

	 	(14)	If requested by Landlord from time to time during the Term of the Lease, the Roof Equipment shall be installed or relocated in such a way, and with appropriate
screening materials (to be provided at Tenant’s sole cost and expense) so as to minimize the visibility of the Roof Equipment from any vantage point on the ground level of the Property or the public streets adjoining the Property; and

  

	 	(15)	Tenant shall remove or relocate Tenant’s Roof Equipment, at Landlord’s direction, if such Roof Equipment interferes with the communications devices of
Landlord and other tenants and licensees in such Building that were installed prior to Tenant’s installation of the Roof Equipment. 

 18.2 Relocation. Landlord shall have the right, upon thirty (30) days notice to Tenant, to require Tenant to relocate the Roof Equipment to another area on the roof of the Ten P.O.
Square Building/10 P.O. Square Building equally suitable for Tenant’s use. In such event, Tenant shall on or before the thirtieth (30th) day after Landlord gives such notice, relocate the Roof Equipment and Landlord shall reimburse Tenant
for all reasonable costs and expenses incurred by Tenant in connection with said relocation. 
 ARTICLE 19 
 SPECIAL SURRENDER PROVISION FOR BASEMENT PREMISES 
 19.1 Special Surrender Provision. Subject to the full and complete satisfaction of the Surrender Conditions Precedent (as hereinafter defined), Tenant shall have the option from time to time
to surrender all or a portion of the Basement Premises to Landlord and to terminate its obligations with respect to all or a portion of the Basement Premises in accordance with the provisions of this Article 19; provided, however, Tenant shall give
not less than ninety (90) days prior written notice (a “Surrender Notice”) thereof to Landlord. The Surrender Notice shall specify the effective date for such surrender of the Basement Premises (or the portion thereof), which date is
referred to herein as the “Surrender Date.” For purposes of this Section 19.1, the “Surrender Conditions Precedent” shall mean the following: (i) Tenant properly gives to Landlord a Surrender Notice,
(ii) both on the date the Surrender Notice is given and on the Surrender Date, no Event of Default shall have occurred under this Lease then exists; and (iii) if Tenant elects to surrender a portion but not all of the Basement Premises,
then any portion of the Basement Premises which is surrendered must in the reasonable judgement of Landlord be satisfactorily segregated and separated from the other portions of the Basement Premises which are retained by Tenant, and the surrendered
portions must be reasonably accessible to and usable by other tenants of the Buildings. 
 Provided that all of the Surrender
Conditions Precedent have been fully and completely satisfied, then the term of this Lease solely with respect to the Basement Premises (or the respective portion thereof) shall end and expire, the Basic Rent shall be adjusted to reflect the

  

 -67- 

 
removal of the Basement Premises (or the respective portion thereof) from the Premises, and all of the right, title and interest of the Tenant in and to the Basement Premises (or the respective
portion thereof) shall terminate and be extinguished, with the same force and effect as if such Surrender Date was the expiration date of the term of this Lease solely with respect to the Basement Premises (or the respective portion thereof). Any
such termination of this Lease with respect to the Basement Premises (or the respective portion thereof) shall be subject to and in accordance with all of the terms and conditions of this Lease, including, without limitation, Sections 12.1
and 12.2 hereof. Notwithstanding any such surrender of the Basement Premises (or the respective portion thereof), the Lease shall remain in full force and effect for and with respect to all of the Premises (excepting only the Basement
Premises or the respective portion thereof) in accordance with the terms and conditions thereof. After the surrender thereof, Tenant shall have no further rights or claims, of any kind, with respect to the Basement Premises and/or the respective
portion thereof. 
 ARTICLE 20 
 RIGHT OF FIRST OFFER TO PURCHASE PROPERTY 
 20.1 Right of
First Offer. 
 (a) If Landlord should, in Landlord’s sole and exclusive judgment, at any time
during the Term of this Lease determine that it would like to “sell” (as hereinafter defined) the entire Property to a third party buyer which is not an Affiliate of Landlord or an Affiliate of any partner or member of Landlord or any of
their respective Affiliates, and provided that the conditions precedent set forth in subsection 20.1 (b) are satisfied, then prior to entering into a binding written agreement to sell the Property to such third parties Landlord shall
deliver to Tenant a notice (the “Offer Notice”). The Offer Notice shall set forth the price at which Landlord intends to offer the Property for sale (the “Offering Price”), together with such other
terms and conditions (including any deferred payment of the purchase price, earnest money requirements and closing date) that Landlord determines to be material to the sale. 
 (b) The conditions precedent to Landlord’s obligation to offer to sell the Property to Tenant are as follows:
(i) no Event of Default or condition or state of facts which with the passage of time or giving of notice, or both, would constitute an Event of Default then exists, (ii) this Lease is then in full force and effect, and (iii) Boston
Private Financial Holdings, Inc. and/or Affiliates of Boston Private Financial Holdings, Inc. is (or are) occupying not less than eighty percent (80%) of the rentable area of the Premises then demised under this Lease. 
 (c) For the purposes of this Article 20, “sell” or “sale” shall mean an arms-length sale of the fee
simple interest of Landlord in the entire Property to a third party unaffiliated purchaser. Without limitation, in no event shall a “sale” include any direct or indirect sale of the Property to an Affiliate (or Affiliates) of Landlord, or
any direct or indirect transfer or conveyance of interests in Landlord, or any financing transactions (including the granting of mortgages or other encumbrances, or a sale or transfer pursuant to a “sale/leaseback” financing transaction or
other financing transaction). 
  

 -68- 

 (d) The rights granted to Tenant in this Article 20 are personal to Boston
Private Financial Holdings, Inc., and may not be assigned or transferred to, or exercisable by, any other persons or entities. 
 20.2 Acceptance of Offer. 
 (a) Provided that all of the conditions
precedent set forth in this Subsection 20.1(b) are fully satisfied by Tenant, Tenant shall have the option, exercisable by Tenant delivering written notice (the “Purchase Acceptance Notice”) to Landlord within fourteen
(14) calendar days after delivery by Landlord of the Offer Notice, to accept the offer to purchase the entire Property upon all of the terms and conditions set forth in the Offer Notice, including the purchase price and other terms and
conditions set forth therein. Time shall be of the essence as to Tenant’s giving of the Purchase Acceptance Notice. If (a) Tenant fails to deliver a Purchase Acceptance Notice within such fourteen (14) day period, or (b) if
Tenant timely delivers a Purchase Acceptance Notice as aforesaid but does not timely deliver a deposit as described in Subsection 20.2(b) below, then Tenant shall be deemed to have rejected the option to purchase the Property. In such event, Tenant
shall have no further rights or claims with respect to the purchase of the Property, Landlord shall have no further liabilities or obligations to Tenant pursuant to this Article 20, and Landlord may elect to sell the Property to 3rd parties upon such terms and conditions as Landlord may determine in
its sole discretion. 
 (b) If Tenant timely and validly exercises the Right of First Offer and elects to
purchase the Property, concurrent with the delivery of the Purchase Acceptance Notice, as a condition to the effectiveness thereof, Tenant shall deliver to a title insurance company or broker designated by Landlord a deposit in the amount of ten
percent (10%) of the Offering Price as a deposit (unless a lesser amount is specified as the deposit in the Offer Notice). The delivery by Tenant of a Purchase Acceptance Notice (together with said deposit) shall be deemed acceptance of
Landlord’s offer as contained in the Offer Notice and thereafter Tenant shall be unconditionally obligated to purchase the entire Property at the Offering Price and upon said other terms and conditions as contained in the Offer Notice.

 (c) If Tenant timely and validly delivers the Purchase Acceptance Notice and the deposit and elects to
purchase the Property, then the purchase by Tenant of the Property shall occur on the date which is fifty-nine (59) calendar days after the date of Tenant’s delivery of the Purchase Acceptance Notice. In the event of Tenant’s default
with respect to such purchase, Landlord’s sole remedy shall be to retain the deposit as liquidated damages and not as a penalty, it being understood that Landlord’s actual damages for non-performance by Tenant may be difficult to
ascertain. If the sale does not take place for reasons not the fault of Tenant, the deposit shall be promptly refunded to Tenant. Any interest earned on the deposit shall be paid to the party ultimately entitled to receive the deposit. 

 

 -69- 

 20.3 Tenant’s Failure to Accept Offer. 
 (a) If a Purchase Acceptance Notice and deposit are not received by Landlord within such twenty (20) day period, or if
in the Purchase Acceptance Notice, Tenant declines to purchase the Property, or if Tenant fails to unconditionally accept the offer on all of the terms and conditions specified in the Offer Notice, then in any such event Tenant shall conclusively be
deemed to have waived its rights to purchase the Property, Landlord shall have no further liabilities or obligations to Tenant under this Article 20, and Landlord shall be free to sell the Property to any third party buyer on such terms and
conditions as Landlord may determine in its sole discretion. 
 (b) At any time and from time to time, as
reasonably requested by Landlord, upon not less than ten (10) days’ prior notice, Tenant agrees to execute, acknowledge and deliver to Landlord a statement in writing and in recordable form certifying, if such be the case, that
Tenant’s right of first offer provided in this Article 20 has lapsed, expired or been waived, or is otherwise not applicable with respect to any particular transaction, it being intended that any such statement delivered pursuant hereto may be
relied upon by all others with whom Landlord and its successors from time to time may be dealing. 
 20.4
Inapplicability. In no event shall the provisions of this Article 20 apply to a sale pursuant to an exercise of a power of sale or a foreclosure by a mortgagee or the acceptance of a deed in lieu of foreclosure by such mortgagee or its
nominee or to any subsequent sale by the owner of the Property. 
 20.5 Time is of Essence. Time is of the essence
of this Article 20. 
 ARTICLE 21 
 ATM MACHINE 
 21.1 As an appurtenance to the Premises, for
and with respect to the Term of this Lease, Tenant is hereby granted, subject to this Article 21 and the provisions of this Lease and such other requirements as shall be imposed by Landlord from time to time, the right to install, secure,
maintain, replace and operate in the location set forth on Exhibit G annexed hereto (the “ATM Space”), an automatic teller machine together with all ancillary equipment, mountings, piping, duct work, venting, conduit, wiring
and support, as shall be reasonably necessary for the operation thereof, (collectively the “ATM”). The exact location and dimensions of the ATM shall be subject to Landlord’s approval in all respects. Except as set forth in
this Article 21, there shall be no Basic Rent, Additional Rent or other charges payable to Landlord in connection with the ATM.

 21.3 No displays or signs, whether temporary or permanent, shall be affixed, installed or attached to the ATM or in the ATM Space
without the prior written approval by Landlord in each instance. 
  

 -70- 

 21.4 In the performance of any installation, alteration, repair, maintenance, removal
and/or any other work with respect to the ATM Space or the ATM, Tenant shall comply with all of the applicable provisions of this Lease and all of the provisions of this Lease shall be applicable to the ATM Space as if the ATM Space was part of the
Premises. 
 21.5 (a) If, at any time during the Term, Landlord, in its judgment, shall determine that it is necessary to
move the ATM to another area within the Buildings, then Landlord may give notice thereof to Tenant (which notice shall have annexed thereto a plan on which such other area (the “Substitute ATM Space”) shall be substantially
identified), which Substitute ATM Space shall be acceptable to Tenant in its reasonable discretion. Unless within ten (10) days after receipt of Landlord’s notice (time being of the essence thereof), Tenant notifies Landlord of its
objection to the Substitute ATM Space, which notice specifies the reasons for such objection and identifies other acceptable alternative locations, then the proposed Substitute ATM Space shall be considered to be acceptable to Tenant. Within 30 days
of receipt of Landlord’s notice (or, if a governmental permit is required to be obtained for installation of the ATM in the Substitute ATM Space, then, within 30 days of the obtaining of such permit (which Tenant shall make prompt application
for, with Landlord’s reasonable cooperation), Landlord, at its sole cost shall move the ATM to the Substitute ATM Space (with only a commercially reasonable lapse of service) which shall then become the ATM Space hereunder and the original ATM
Space shall be deleted from the coverage of this Lease. 
 (b) Tenant’s operation or use of the ATM shall not prevent or
interfere with the operation or use of any equipment of any present or future tenant or occupant of the Buildings and/or of Landlord. If, at any time, Landlord shall reasonably determine that the ATM causes interference with other operations or
equipment, then Landlord may so notify Tenant, and Landlord may require Tenant to replace the ATM with another ATM which would not cause such interference (the “Replacement ATM”). Tenant, within 30 days of receipt of such notice or,
if a government permit is required to install the Replacement ATM, then within 30 days of the obtaining of such permit (which Tenant shall make prompt application for, with Landlord’s cooperation but at no cost to Landlord), shall replace the
ATM with the new non-interfering Replacement ATM which shall then be deemed to be the ATM hereunder. 
 21.6 Landlord has
made no warranties or representations as to the condition or suitability of the ATM Space or the Building (or the electricity available to the ATM Space) for the installation, use, maintenance or operation of the ATM, and Tenant agrees to accept
same in its “as is” condition and without any work or alterations to be made by Landlord. 
 21.7 If at any
time the ATM ceases operating for more than one hundred twenty (120) consecutive days, then promptly thereafter Tenant shall, at its cost and expense, remove the ATM and perform all repairs required to restore the ATM Space to its previous
condition. Thereafter, Tenant shall have no further rights or claims to the ATM Space and Landlord shall have no further liabilities or obligations with respect thereto.

the Premises, for and with respect to the Term of this Lease, Tenant is hereby granted, subject to this Article 22, Article 5 of this Lease and all of the other provisions of this Lease and such other requirements as shall be
imposed by Landlord from time to time, the right to install, secure, maintain, replace and operate in either (a) the location designated as “A”, or (b) the location designated as “B”, each as set forth on

etc., with Landlord’s generator, Tenant shall pay the incremental costs of such facilities in excess of the costs that Landlord would incur but for such sharing and shall reimburse Landlord for all such costs (including design, installation and
construction costs) within 30 days after demand. 
 22.2 Tenant is also granted, subject to the provisions of
Article 5 and of this Article 22 and such other requirements as may be imposed by Landlord, the right to install, operate and maintain in shaft or riser space to be reasonably designated by Landlord an electric riser from the Generator

and 23.2 shall become null and void and of no further force or effect, and Tenant shall have no further options or other rights to lease either the 2007 Expansion Space or the 2008 Expansion Space pursuant to this Article 23. In
such event, all of the obligations of Landlord to lease either the 2007 Expansion Space or the 2008 Expansion Space to Tenant shall be considered to have been fully and completely satisfied, and neither Landlord nor Tenant shall have any further
rights, liabilities or obligations with respect to either the 2007 Expansion Space or the 2008 Expansion Space under this Article 23.

 The purpose of this Plan is to provide incentive and reward to certain
employees of Boston Private Financial Holdings, Inc. (the “Company”) and its affiliates who contribute to the long-term success of the Company. 
 The Plan shall be unfunded and maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees within the meaning of Sections
210(2), 301(a)(3) and 401(a)(1) of the Employee Retirement Income Security Act of 1974, as amended.

hereby adopts the Plan pursuant to the terms and provisions set forth below.

 (a) any “person” (as such term is defined in Sections 13(d) and 14(d) of the Securities Exchange Act
of 1934 (the “Act”)) (other than the Company, any trustee or other fiduciary holding securities under an employee benefit plan or trust of the Company, or any corporation owned, directly or indirectly, by the stockholders of the Company in
substantially the same proportions as their ownership of stock of the Company) becomes a “beneficial owner” (as such term is defined in Rule 13d-3 promulgated under the Act), directly or indirect1y, of securities of the Company
representing at least twenty five percent (25%) or more of the combined voting power of the Company’s then outstanding securities; 
  

 2 

 (b) persons who, as of January 1, 2001, constituted the Company’s
Board (the “Incumbent Board”) cease for any reason, including without limitation, as a result of a tender offer, proxy contest, merger or similar transaction, to constitute at least a majority of the Board of Directors of the Company,
provided that any person becoming a director of the Company subsequent to January 1, 2001, whose election or nomination for election was approved by at least a majority of the directors then comprising the Incumbent Board shall, for purposes of this
Section 1.5, be considered a member of the Incumbent Board; or 
 (c) the stockholders of the Company shall
approve (i) any consolidation or merger of the Company or its subsidiaries where the stockholders of the Company, immediately prior to the consolidation or merger, would not, immediately after the consolidation or merger, beneficially own (as
such term is defined in Rule 13d-3 under the Act), directly or indirectly, shares representing in the aggregate 80% or more of the voting shares of the corporation issuing cash or securities in the consolidation or merger (or of its ultimate parent
corporation, if any), (ii) any sale, lease, exchange or other transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially all of the assets of the Company or
(iii) any plan or proposal for the liquidation or dissolution of the Company. 
 1.6 “Code” means the Internal

Participant’s Account after December 31, 2004 and amounts credited to a Participant’s Account before January 1, 2005 but which becomes vested after December 31, 2004, and deemed investment adjustments thereon.

Company pursuant to the Plan. 
 1.12 “Disability” or “Disabled” with respect to the Pre-2005 Deferred

of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, or (ii) by reason of any medically determinable

 7 

 ARTICLE II - ELIGIBILITY 
 2.1 Eligibility. An individual is eligible to participate in the Plan if he or she: 
 (a) is an Employee; 
 (b) is a member of the senior management team of the Participating Employer; and 
 (c) is approved by the Participating Employer to participate in this Plan. 
 2.2
Cessation of Eligibility. An Eligible Employee shall become ineligible to participate on the date such individual no longer satisfies the requirements of Section 2.1. An Employee’s eligibility to participate in the Plan with respect
to any particular Plan Year does not guarantee continued eligibility to participate in any future Plan Year. 
 In the event an
individual’s status changes from Eligible Employee to ineligible Employee during a Plan Year, or if an Eligible Employee ceases to be an Employee in connection with a restructuring or reorganization of a Participating Employer that results in
such individual becoming a self-employed individual performing personal services for a Participating Employer, deferrals under the Plan, if any, shall continue for the balance of such Plan Year in accordance with such individual’s Deferred
Compensation Agreement to the extent the Participant continues to receive Compensation or earned income from self-employment from a Participating Employer in such Plan Year. 
  

 8 

 ARTICLE III - DEFERRAL ELECTIONS 
 3.1 Deferred Compensation Agreement. An Eligible Employee may elect to defer a portion of his or her Compensation by entering into a
Deferred Compensation Agreement with a Participating Employer pursuant to the rules set forth in this Article III. The Deferred Compensation Agreement shall be made on a form supplied by the Company and shall be filed with the Company’s Human
Resources Department (or its designee) in accordance with procedures established by the Company. A Deferred Compensation Agreement shall become effective only if the Company determines that such Agreement complies with the rules of the Plan and the
Company accepts and approves the Agreement. 
 The foregoing notwithstanding, a Participant’s deferrals of Compensation
under the Plan shall be suspended for any period of time required by regulations promulgated under Section 401(k) of the Code in the event the Participant receives a hardship distribution from the 401(k) Plan. 
 3.2 Timing of Deferred Compensation Agreement. 
 (a) Deferrals of Base Compensation. An Eligible Employee may enter into a Deferred Compensation Agreement with respect
to his or her Base Compensation prior to January 1 of each Plan Year. The Deferred Compensation Agreement shall apply to Base Compensation earned in the immediately following Plan Year, and shall be irrevocable. 
 (b) Deferrals of Commissions. An Eligible Employee may enter into a Deferred Compensation Agreement with respect to
his or her Commissions prior to January 1 of each Plan Year. The Deferred Compensation Agreement shall apply to Commissions earned in the immediately following Plan Year, and shall be irrevocable. 
 (c) Deferrals of Incentive Compensation. An Eligible Employee may enter into a Deferred Compensation Agreement with
respect to Incentive Compensation prior to the beginning of the Plan Year in which the Participant performs the services relating to such Incentive Compensation. Such deferral election shall be irrevocable. 
  

 9 

 (d) Rules for Newly Eligible Employees. Notwithstanding (a),
(b) and (c) above, an Employee who first becomes an Eligible Employee after the annual enrollment period for a Plan Year may enter into a Deferred Compensation Agreement no later than 30 days after he or she becomes eligible. For the Plan
Year in which such Employee first becomes eligible, the Deferred Compensation Agreement (i) shall apply with respect to Base Compensation and Commissions earned after the pay period that the Deferred Compensation Agreement is executed and
(ii) shall not apply to Incentive Compensation earned in such Plan Year. For Plan Years beginning after the Employee first becomes eligible, the rules set forth in (a), (b) and (c) above shall apply. 
 3.3 Amount of Deferrals. 
 (a) From Base Compensation. An Eligible Employee may elect to defer up to 25% of his or her Base Compensation, in increments of 1%. 
 (b) From Commissions. An Eligible Employee may elect to defer up to 100% of his or her Commissions, in increments of
5%. 
 (c) From Incentive Compensation. An Eligible Employee may elect to defer up to 100% of his or her
Incentive Compensation, in increments of 5%. 
 A Deferral Election shall be automatically reduced if the Company determines
that such action is necessary to meet Social Security and Medicare tax withholding obligations. 
  

 10 

 3.4 Deferral Period. 
 (a) General. At the time an Eligible Employee defers Compensation pursuant to a Deferred Compensation Agreement for a
Plan Year, the individual must specify a distribution date applicable to such deferrals. The Eligible Employee may elect to defer Compensation for a Plan Year to Separation from Service, as set forth in Section 3.4(b) below, and/or to an
In-Service Distribution Date, as set forth in Section 3.4(c) below. A Participant may make separate elections with respect to deferrals of Base Compensation described in Section 3.2(a) of the Plan, deferrals of Commissions described in
Section 3.2(b) of the Plan and deferrals of Incentive Compensation described in Section 3.2(c) of the Plan. 
 (b) Deferrals to Separation from Service. An Eligible Employee may irrevocably elect in his or her Deferred Compensation Agreement for a Plan Year to defer Compensation to Separation from Service. The Company shall establish a
Retirement Subaccount on behalf of each Eligible Employee representing Compensation deferred to Separation from Service, and earnings thereon. Payments from Retirement Subaccounts shall be made at such time and in such manner as provided in
Section 6.1. 
 (c) Deferrals to an In-Service Distribution Date. An Eligible Employee may
irrevocably elect in his or her Deferred Compensation Agreement for a Plan Year to defer Compensation to an In-Service Distribution Date. Deferrals to an In-Service Distribution Date shall be subject to the following requirements: 
 (i) In-Service Distribution Date. The In-Service Distribution Date must be a date at least two full calendar years
after the date of such Deferred Compensation Agreement. 
 (ii) In-Service Distribution Subaccount. The
Company shall establish an In-Service Distribution Subaccount within the Eligible Employee’s Deferred Compensation Account to which deferrals relating to a particular In-Service Distribution Date, and earnings thereon, shall be credited. Once
an In-Service Distribution

  

 11 

 
Subaccount is established a Participant may elect in subsequent Deferred Compensation Agreements to defer additional Compensation to such Subaccount, up to and including the third calendar year
prior to the calendar year containing the In-Service Distribution Date. 
 (iii) Payments. Payments from
In-Service Distribution Subaccounts shall be made at such time and in such manner as provided in Section 6.1. 
 3.5
Vesting of Retirement and In-Service Distribution Subaccounts. Participants are fully vested in their Retirement Subaccount and In-Service Distribution Subaccount(s). 
  

 12 

 ARTICLE IV - PARTICIPATING EMPLOYER MATCHING CONTRIBUTIONS 
 4.1 Eligibility for Participating Employer Matching Contribution. An individual shall be eligible for a Participating Employer
Matching Contribution, if any, under this Article IV for a Plan Year only if such individual has made the maximum elective deferrals to the 401(k) Plan permitted under Section 402(g) of the Code for such Plan Year, or has made the maximum
elective deferral permitted under the terms of the 401(k) Plan for such Plan Year, or such individual’s compensation taken into account under the 401(k) Plan was limited by Code Section 401(a)(17) for such Plan Year, or such
individual’s contributions to the 401(k) Plan were limited by Code Section 415 for such Plan Year. 
 4.2 Amount of
Participating Employer Matching Contribution. 
 (a) General. Each Participating Employer shall
determine, in its sole discretion, whether to make Participating Employer Matching Contributions for a Plan Year on behalf of eligible Participants employed by such Participating Employer. 
 (b) Amount. A Participant’s Participating Employer Matching Contribution for such Plan Year, if any, shall
be determined in accordance with the following procedure:

for such Plan Year.

for employer matching contributions under the 401(k) Plan for such Plan Year.* 
 Step Three: Multiply Step One by Step
Two. 
 Step Four: Determine the Participant’s total deferrals of Base Compensation to the 401(k) Plan in such Plan
Year.

 Step Seven: Determine the lesser of Step Three and Step Six. 
 Step Eight: Multiple Step Seven by the rate of employer matching contributions under the 401(k) Plan for such Plan Year determined as
of the last day of such Plan Year. * 
 Step Nine: Determine the employer matching contributions allocated to the
Participant’s 401(k) Plan account for such Plan Year. 
 Step Ten: Subtract Step Nine from Step Eight. 
  
 *For example, if a 401(k)
plan matches employee contributions up to 6% of compensation on a dollar for dollar basis, 6% would be used in Step Five and 100% would be used in Step Eight. 
 (c) Additional Matching Contribution. Each Participating Employer shall have the discretion to make an additional
Participating Employer Matching Contribution on behalf of an eligible Participant in any Plan Year to the extent such Participating Employer deems such contribution necessary to satisfy the intent of the Plan. 
 (d) Nonduplication of Match. It is intended that that there be no duplication of Participating Employer Matching
Contributions under this Plan and the 401(k) Plan. The Company shall have the absolute discretion to reduce a Participating Employer Matching Contribution under this Plan in order to effectuate this intent. 
 4.3 Participating Employer Matching Contribution Subaccount. The Company shall establish a Participating Employer Matching
Contribution Subaccount on behalf of each Eligible Employee to which Participating Employer Matching Contributions, and earnings thereon, shall be allocated. 
 4.4 Vesting of Participating Employer Matching Contribution Account. A Participant shall vest in his or her Participating Employer Matching Contribution Account at the same time and at the same
rate as his or her matching contributions under the Boston Private Financial Holdings, Inc. 401(k) Profit Sharing Plan. The foregoing notwithstanding, a Participant’s Participating Employer Matching Contribution Subaccount shall be fully vested
upon the earliest to occur of the following: (a) the Participant’s death or Retirement, (b) a Change in Control, and (3) termination of the Plan in accordance with Section 8.1. 
  

 14 

 4.5 Payment of Participating Employer Matching Contribution Subaccount. Vested
Participating Employer Matching Contribution Subaccounts shall be paid at such time and in such manner as provided in Section 6.3. 
  

 15 

 ARTICLE V - DEFERRED COMPENSATION ACCOUNT 
 5.1 Establishment of Deferred Compensation Accounts and Subaccounts. The Company shall establish and maintain for each Participant a
hypothetical (bookkeeping) account called the Deferred Compensation Account. Such Account shall be segregated from the other accounts on the books and records of the Company as an unfunded and unsecured liability of the Company to the Participant.
Subaccounts shall be maintained as determined necessary by the Company. Accounts and subaccounts are maintained strictly for accounting purposes and do not represent separate funding of the benefits under the Plan. Any reference to
“contributions to” or “payments from” Participant Accounts, or similar phrases, are for convenience only and do not reflect any separate funding of the benefits under the Plan. 
 5.2 Allocations to and Distributions From Deferred Compensation Accounts. The Company shall credit to each Participant’s Account
an amount equal to the percentage of such Participant’s Base Compensation, Commissions and Incentive Compensation which he or she has elected to defer on a timely-filed Deferred Compensation Agreement. Such deferrals shall be credited as of the
date the Participant would have received such amount if not for the Participant’s deferral election. 
 The Company shall
credit to a Participant’s Account an amount equal to the Participating Employer Matching Contribution to which he or she is entitled under Article IV of the Plan. Participating Employer Matching Contributions will be credited to the
Participant’s Account as soon as administratively practicable after the end of each Plan Year. 
 Any distribution with
respect to a Deferred Compensation Account shall be charged to such Account as of the date the distribution is made by the Participating Employer or the trustee of any Rabbi Trust established for the Plan. 
  

 16 

 5.3 Selection of Investment Vehicle. Each Participant shall specify, in such manner
as prescribed by the Company, the allocation of his or her Account among investment indices available under the Plan. To the extent permitted by the Company, a Participant may make separate investment allocations with respect to his or her
Retirement and In-Service Distribution Subaccounts. The Participant’s investment allocation with respect to his or her Retirement Subaccount (or In-Service Distribution Subaccount if the Participant does not have a Retirement Subaccount) shall
also apply to the Participant’s Participating Employer Matching Contribution Subaccount. 
 An individual’s selection
of an investment index will have no bearing on the actual investment or segregation of Company assets, but will be used as the basis for making adjustments to the such individual’s Account as described below in Section 5.4 of the Plan. A
Participant can change his or her investment index or indices at such time, and in such manner, as determined by the Company. The Company may change the investment indices available under the Plan at any time in its absolute discretion. 

5.4 Adjustment of Deferred Compensation Account. As of the last day of each calendar month, and at such other times as determined
in the sole discretion of the Company, a Participant’s Deferred Compensation Account shall be credited with deemed net income, gain and loss, including deemed net unrealized gain and loss, based on the hypothetical investment directions made by
the Participant in accordance with section 5.3. Such earnings and losses will continue to accrue during any period in which installments are paid pursuant to Article VI. 
  

 17 

 ARTICLE VI - BENEFIT PAYMENTS 
 6.1 Payment of Retirement Subaccount. 
 (a) Payment upon Retirement or Disability. Subject to Section 6.6, payment from each of a Participant’s Retirement Subaccounts shall be made, or shall commence, within 60 days after the

 (i) Lump Sum. A single lump sum payment.

that installments due to be paid in a Plan Year shall be paid during the Plan Year. 
 (b) A Participant may
change his or her election regarding the form of payment at Retirement or Disability with respect to his or her Pre-2005 Deferred Compensation Account provided the change is received by the Company, on a form prescribed by the Company, at least 13
months prior to the Participant’s Retirement or Disability. A Participant may modify the form or timing of benefit payment at Retirement or Disability with respect to his or her Post-2004 Deferred Compensation Account so long as such
modification is made at least 12 months prior to the original payment date, the new payment date is at least five years from the original payment date and the modification does not take effect for at least 12 months after the modification date. The
foregoing restrictions do not apply to modifications made in 2005, 2006, 2007 or 2008 to the extent permitted by Section 409A of the Code and the guidance promulgated thereunder. 
  

 18 

 (c) Payment upon Separation from Service. Subject to
Section 6.6, in the event of Separation from Service prior to Retirement, a Participant’s Retirement Subaccount shall be paid in a single lump sum. Subject to Section 6.6, payments shall be made within 60 days after the
Participant’s Separation from Service. 
 6.2 Payment of In-Service Distribution Subaccount. A Participant’s
In-Service Distribution Subaccount shall be paid in a single lump sum. Payment shall be made after the earlier of (a) the Participant’s In-Service Distribution Date, or (b) the date the Participant Separates from Service for any
reason other than Retirement. If payment of a Participant’s Subaccount is on account of Separation from Service, subject to Section 6.6, payments shall be made within 60 days after the Participant’s Separation from Service.

 The foregoing notwithstanding, if a Participant’s Retirement or Disability occurs prior to the Participant’s
In-Service Distribution Date with respect to an In-Service Withdrawal Subaccount, the balance of such Subaccount shall be paid in a lump sum or in installments as elected by the Participant for distribution of his or her Retirement Subaccount in
accordance with the provisions of Section 6.1. 
 6.3 Payment of Participating Employer Matching Contribution
Subaccount. 
 (a) Payment upon Separation from Service Prior to Retirement. In the event of
Separation from Service prior to Retirement, the vested portion of the Participant’s Participating Employer Matching Contribution Subaccount shall be paid in a single lump sum and the nonvested portion shall be forfeited. Subject to
Section 6.6, payment shall be made within 60 days after the Participant’s Separation from Service. 
  

 19 

 (b) Payment upon Retirement or Disability. Upon a Participant’s
Retirement or Disability, his or her Participating Employer Matching Contribution Subaccount shall be paid at the same time, and in the same form, as the Participant’s Retirement Subaccount, as elected by the Participant pursuant to
Section 6.1(a) of the Plan. 
 6.4 Small Benefit. Notwithstanding any election made by the Participant, if upon a
Participant’s Separation from Service, the vested amount in all his or her Deferred Compensation is less than $100,000, it shall be paid out in a lump sum. 
 6.5 Benefit Payments Upon Death. In the event of the death of a Participant, benefits being paid in the form of installments shall cease, and a death benefit shall be paid to the Participant’s
Beneficiary(ies). The benefit payable to the Participant’s Beneficiary(ies) shall be one-hundred percent (100%) of the vested balance of such Participant’s Deferred Compensation Account. The benefit shall be paid in a single lump sum
within 60 days after the Participant’s date of death. If a Participant has not designated a Beneficiary, or if no designated Beneficiary is living on the date of death, the death benefit shall be paid to the Participant’s spouse. If such
individual’s spouse is not then living or the Participant is unmarried at the time of death, then the death benefit shall be paid to the Participant’s estate. 
 6.6 Time of Payment for Post-2004 Deferred Compensation Accounts. No payment of any Post-2004 Deferred Compensation Accounts may be made under this Plan if such payment is to be made as a result of
such Participant’s Separation from Service until at least six months and one day after the Participant’s Separation from Service. Any payments that would have been made to the Participant during the six-month delay period but for the
operation of this paragraph shall (i) be made in a lump sum to the Participant in the seventh month after the Participant’s Separation from Service, and (ii) be credited with earnings in accordance with Section 5.4 during the
six-month delay. 
  

 20 

 ARTICLE VII - ADMINISTRATION OF THE PLAN 
 7.1 Plan Administration. The Plan shall be administered by the Administrator. The Administrator shall have the right to make such
rules and regulations as it deems appropriate for the efficient administration of the Plan, to construe and interpret the Plan, including any uncertain Plan terms, to make factual determinations to decide all questions of eligibility, and to
determine the amount and time of payment of awards hereunder to the fullest extent provided by law and in its sole discretion; any interpretations or decisions so made will be conclusive and binding on all persons having any interest in the Plan.

 7.2 General Powers of Administration. The Administrator shall be entitled to rely conclusively upon all tables,
valuations, certificates, opinions and reports furnished by any actuary, accountant, controller, counsel or other person employed or engaged by the Company with respect to the Plan. The Administrator will have full power to administer the Plan in
all of its details, subject to applicable requirements of law. For this purpose, the Administrator’s powers will include, but will not be limited to, the following authority, in addition to all other powers provided by this Plan: 
 (a) To make and enforce such rules and regulations as it deems necessary or proper for the efficient administration of the
Plan, including the establishment of any claims procedures that may be required by applicable provisions of law; 
 (b) To interpret the Plan, its interpretation thereof in good faith to be final and conclusive on all persons claiming benefits under the Plan; 
 (c) To decide all questions concerning the Plan and the eligibility of any person to participate in the Plan; 
 (d) To appoint such agents, counsel, accountants, consultants and other persons as may be required to assist in administering the Plan; and

 22 

 ARTICLE VIII - AMENDMENT OR TERMINATION 
 8.1 Amendment or Termination. The Company reserves the right to amend or terminate the Plan when, in the sole opinion of the Company,
such amendment or termination is advisable. 
 The Company (or a Participating Employer with respect to its Participants) may
partially terminate the Plan by refusing to accept any additional Deferred Compensation Agreements. The Plan shall otherwise continue to operate in accordance with its terms. 
 The Company (or a Participating Employer with respect to its Participants) may completely terminate the Plan. Notwithstanding any provision
of this Plan to the contrary, in the event of complete termination, the Plan (or the portion of the Plan applicable to a withdrawing Participating Employer) shall cease to operate, and the Company shall pay out to each Participant (or the
Beneficiary of a deceased Participant) his or her Pre-2005 Deferred Compensation Account balance in quarterly installments over a three (3)-year period, as if the Participant had retired as of the effective date of the complete termination. In the
Company’s sole discretion, the Company may instead pay each Participant and Beneficiary his or her Account balance in a lump sum. With respect to the Participants’ Post-2004 Deferred Compensation Accounts, the Company may accelerate
distribution only to the extent permitted by Section 409A of the Code and the regulations promulgated thereunder. 
 8.2
Effect of Amendment or Termination. No amendment or termination of the Plan shall directly or indirectly reduce the balance of any Deferred Compensation Account held hereunder as of the effective date of such amendment or termination or

 23 

 ARTICLE IX - GENERAL PROVISIONS 
 9.1 Payment of Benefits from General Assets; Unsecured Creditor Status for Participants. All benefits payable under this Plan to or
on behalf of Participants shall be paid from the general assets of the Company or of a Participating Employer. A Participating Employer shall not be required to set aside any funds to discharge its obligations hereunder, but such Participating
Employer may set aside such funds if it chooses to do so. Any setting aside of amounts, or acquisition of any insurance policy or any other asset, by the Company (or other Participating Employer) with which to discharge its obligations hereunder in
trust or otherwise, shall not be deemed to create any beneficial ownership interest in any Employee, Participant, or Beneficiary, and legal and equitable title to any funds so set aside shall remain in the Company (or the other Participating
Employer), and any recipient of benefits hereunder shall have no security or other interest in such funds. The rights of the Participant and his Beneficiary(ies) under this Plan shall be no greater than the rights of a general unsecured creditor of
the Participating Employers. Any and all funds so set aside shall remain subject to the claims of the general creditors of the Participating Employers, present and future. Any Deferred Compensation Account established for a Participant under this
Plan shall be hypothetical in nature and shall be maintained for recordkeeping purposes only. 
 9.2 No Guarantee of
Benefits. Nothing contained in the Plan shall constitute a guaranty by the Company, Participating Employer, or any other person or entity that the assets of the Company will be sufficient to pay any benefits hereunder. 
 9.3 No Enlargement of Employee Rights. No Participant shall have any right to receive a benefit payment under the Plan except in
accordance with the terms of the Plan. Establishment of the Plan shall not be construed to give any Participant the right to be retained in the service of the Company or other Participating Employer. 
  

 24 

 9.4 Spendthrift Provision. No interest of any Participant in the Plan shall be
subject in any manner to sale, transfer, assignment, pledge, attachment, garnishment, or other alienation or encumbrance of any kind; nor may such interest or right to receive a benefit payment be taken, either voluntarily or involuntarily for the
satisfaction of the debts of, or other obligations or claims against, such Participant. Notwithstanding the foregoing, payment may be made from the Plan to an individual other than the Participant to the extent required in a domestic relations
order. 
 9.5 Incapacity of Recipient. If any person entitled to a benefit payment under the Plan is deemed by the
Company to be incapable of personally receiving and giving a valid receipt for such payment, then, unless and until claim therefor shall have been made by a duly appointed guardian or other legal representative of such person, the Company may
provide for such payment or any part thereof to be made to any other person or institution then contributing toward or providing for the care and maintenance of such person. Any such payment shall be a payment for the account of such person and a
complete discharge of any liability of the Company and the Plan therefor. 
 9.6 Corporate Successors. The Plan shall not
be automatically terminated by a transfer or sale of assets of the Company or by the merger or consolidation of the Company into or with any other entity, but the Plan shall be continued after such sale, merger or consolidation only if and to the
extent that the transferee, purchaser or successor entity agrees to continue the Plan. In the event that the Plan is not continued by the transferee, purchaser or successor entity, then the Plan shall terminate subject to the provisions of Article
VIII. 
 9.7 Limitations on Liability. Notwithstanding any of the preceding provisions of the Plan, neither the
Participating Employers, nor any individual acting as employee or agent of the Participating Employers, shall be liable to any Participant or other person for any claim, loss, liability or expense incurred in connection with the Plan. 
  

 25 

 The Participating Employers do not in any way guarantee any Participant’s Deferred
Compensation Account against loss or depreciation, whether caused by poor investment performance, insolvency of a deemed investment or by any other event or occurrence. In no event shall the employees, officers, directors, or stockholders of the
Participating Employers be liable to any individual or entity on account of any claim arising by reason of the Plan provisions or any instrument or instruments implementing its provisions, or for the failure of any Participant, Beneficiary or other
individual or entity to be entitled to any particular tax consequences with respect to the Plan or any credit or payment hereunder. 
 Any payment made in good faith in accordance with provisions of the Plan shall be a complete discharge of any liability for the making of such payment under the provisions of this Plan. 
 9.8 Tax Withholding and Reporting. The Company shall have the right to deduct any required withholding taxes from any payment made
under the Plan. The Participating Employers shall not be obligated to pay, or reimburse the Participant or Beneficiary for, any income or other taxes or penalties that may be imposed on the Participant or Beneficiary as a result of this Plan by the
Internal Revenue Service or any state or other taxing authority. 
 9.9 Liability for Payment. Anything in the Plan to
the contrary notwithstanding, each Participating Employer shall be liable for payments due under this Plan which are based upon its Employees’ participation in the Plan. In the event that is payment due hereunder is based upon participation in
the Plan during employment with two or more participating Employers, each such Participating Employer’s share of the liability will be based on amounts credited and 
  

 26 

 
earnings accrued while the Participant was employed with each such participating Employer. In the event a payment is made under this Plan by the Company on behalf of another Participating
Employer’s employee, the Company shall be entitled to reimbursement from such Participating Employer. 
 9.10 Plan
Expenses. The Company shall have the option to require the Plan to bear the costs incident to the Plan’s operation. If the Company requires that the Plan bear any such costs, each Participant’s Account shall be debited its
proportionate share of such costs, in accordance with rules adopted by the Company and uniformly applied to all Participants. To the extent the Company does not exercise the option to require the Plan to bear the costs incident to the Plan’s
operation, each Participating Employer shall pay a pro-rata portion of such costs, in the manner prescribed by the Company. 
 9.11 Applicable Law. The Plan shall be construed and administered under the laws of the Commonwealth of Massachusetts. 
  

 27

decision denying the claim by filing, in accordance with such procedures as the Administrator may establish, a written appeal which sets forth the documents, records and other information relating to the claim within 60 days (180 days for claims
made due to Disability) after receipt of the notice of the denial from the Administrator. In connection with such appeal and upon request by the Claimant, a Claimant may review (or receive free copies of) all documents, records or other information
relevant to the Claimant’s claim for benefit, all in accordance with such procedures as the Administrator may establish. If a Claimant fails to file an appeal within such period, he or she shall have no further right to appeal. 
  

 29 

 (d) A decision on the appeal by the Administrator shall include a review by
the Administrator that takes into account all comments, documents, records and other information submitted by the Claimant relating to the claim, without regard to whether such information was submitted or considered in the initial claim
determination. The Administrator shall render its decision on the appeal not later than 60 days (45 days for claims due to Disability) after the receipt by the Administrator of the appeal. If special circumstances apply, the 60-day period may be
