(a)    Third Expansion Space Plan. Tenant shall select with the prior approval
of Landlord, not to be unreasonably withheld or delayed, a mutually agreed upon
architectural firm through a competitive bidding

--------------------------------------------------------------------------------

process coordinated by Tenant with no less than three (3) quotes (the
“Architect”) to prepare draft of the space plan for the Third Expansion Premises
(the “Space Plan”). Tenant shall (subject to reimbursement out of the Third
Expansion Tenant Improvement Allowance as set forth below) cause the Architect
to prepare and submit to Landlord for Landlord’s review, the Space Plan. The
Space Plan shall be materially consistent with the Second Expansion Space Plan
for the Second Expansion Premises, as set forth in the Fourth Amendment.
Landlord shall approve or disapprove the Space Plan within five (5) business
days after submittal by Tenant. If Landlord disapproves the Space Plan, Landlord
shall explain in reasonable detail the reason for such disapproval. Landlord and
Tenant shall work together to resolve Landlord’s objections provided that, in
all events, Landlord’s approval is required. Landlord shall contribute an amount
equal to the lesser of (i) the actual third party cost to prepare the Space Plan
and (ii) $0.10 per rentable square foot toward the cost of Tenant’s Space Plan
preparation, which amount shall be in addition to the Tenant Improvement
Allowance outlined in Paragraph 6 and payable after the Space Plan has been
approved by Landlord within thirty (30) days after Landlord’s receipt of a
written invoice from Tenant for the same.

(b)    Third Expansion Plans and Specifications. Upon Landlord’s approval of the
Space Plan, Tenant shall cause Architect to prepare and submit to Landlord for
Landlord’s review, draft Third Expansion Plans and Specifications. The Third
Expansion Plans and Specifications shall be materially consistent with the Space
Plan and the Second Expansion Plans and Specifications for the Second Expansion
Premises, as set forth in the Fourth Amendment. Landlord shall approve or
disapprove the Third Expansion Plans and Specifications within five (5) business
days after submittal by Tenant. If Landlord disapproves the Third Expansion
Plans and Specifications, Landlord shall explain in reasonable detail the reason
for such disapproval. Landlord and Tenant shall work together to resolve
Landlord’s objections provided that, in all events, Landlord’s approval is
required.

(c)    Landlord Delay. If Landlord fails to approve or reject (with a detailed
explanation for such rejection) any submissions of the Space Plan or Third
Expansion Plans and Specifications submitted by or on behalf of Tenant, in each
case, within five (5) business days of receipt of such written request to
approve the same, then Tenant shall send a second written notice (which such
second written notice shall include a copy to Larry Lenrow
(llenrow@TheDavisCompanies.com)), and in the event Landlord fails to approve or
reject (with a detailed explanation for such rejection) within two (2) business
days after second notice, such failure to approve or reject by Landlord shall
constitute a “Landlord Delay”.

6.     Construction of Third Expansion Improvements.

(a)    Third Expansion Premises Construction Budget. After Landlord’s approval
of the Space Plan and the Third Expansion Plans and Specifications, Tenant shall
cause the preparation of an estimate of the costs and expenses to construct the
Third Expansion Improvements for the Third Expansion Premises in accordance with
the approved Third Expansion Plans and Specifications. The cost estimate will
include the actual costs quoted by no less than three (3) contractors
competitively bid by Tenant. The cost estimate will separately state the
Landlord construction management fee of three percent (3%) of the Third
Expansion Tenant Improvement Allowance to be utilized for the Third Expansion
Improvements to have Landlord manage the Third Expansion Improvements (the
“Construction Management Fee”), which shall be deducted monthly based on the
percentage of construction completed, commencing on the first day of the
calendar month immediately following the date on which the Third Expansion
Improvements are commenced. If the quoted estimated cost to construct both the
Third Expansion Improvements in the Space Plan exceeds the total of Third
Expansion Tenant Improvement Allowance, Tenant may cause the Architect to alter
the Space Plan, provided, however, any such requests for changes to a Space Plan
or requests the inclusion of materials or installations in the construction of
the Third Expansion Improvements that delays the construction of the Third
Expansion Improvements shall not extend the Third Expansion Premises Rent
Commencement Date – Phase I or the Third Expansion Premises Rent Commencement
Date – Phase II. Costs associated with any engineered required plans,
construction drawings, and/or as-built drawings for the Third Expansion Premises
and the Construction Management Fee shall be included in the fees or costs
itemized and deducted from the Third Expansion Tenant Improvement Allowance.
Tenant shall select with the prior approval of Landlord, not to be unreasonably
withheld or delayed, a mutually agreed upon general contractor after a

4
        

--------------------------------------------------------------------------------

competitive bidding process with no less than three (3) quotes. Tenant shall
send summaries of all bids to Landlord. Tenant shall finalize the final cost to
construct the Third Expansion Improvements in accordance with the Space Plan
(the “Expansion Space Estimated Final Cost”) and, to the extent such cost
exceeds the Third Expansion Tenant Improvement Allowance (the “Excess Amount”),
Tenant shall have the right to make changes to the Space Plan as set forth above
to limit the Excess Amount. The Excess Amount, if applicable, shall be funded by
Tenant and paid to Landlord as follows: one-third (1/3) within thirty (30) days
after Landlord’s approval of the Space Plan; one-third (1/3) sixty (60) days
after Landlord’s approval of the Space Plan; and one-third (1/3) of the Excess
Amount, ninety (90) days after Landlord’s approval of the Space Plan. Tenant
shall be responsible for 100% of the payment of any additional costs or charges
related to any change orders; provided, Landlord shall be required to reasonably
approve any changes to the Space Plans or Third Expansion Premises Plans and
Specifications. Except as set forth in Section 6(b), Tenant shall not be
entitled to any cost savings or reimbursement in the event the actual costs and
expenses to plan and construct the Third Expansion Improvements are less than
the Third Expansion Tenant Improvement Allowance. Tenant shall not have the
right to use any portion of the Third Expansion Tenant Improvement Allowance for
the Premises, Expansion Premises or Second Expansion Premises. In no event shall
more than fifteen percent (15%) of the Third Expansion Tenant Improvement
Allowance be used toward the cost of the architectural and engineering services
needed to prepare the Third Expansion Plans and Specifications and the Space
Plans, moving expenses, signage, permit fees, architect fees, wiring and
cabling, furniture, data, telephone, audio-visual, security, WiFi, “white
noise”, internet and video systems, including, without limitation, any
specialized supplemental cooling systems for any serve room or for any of the
communications systems or other special rooms.

(b)     Unused Third Expansion Tenant Improvement Allowance. In the event Tenant
does not use the entire Third Expansion Tenant Improvement Allowance for
permitted Third Expansion Improvements by the earlier to occur of (i) May 1,
2018 and (ii) ninety (90) days after the Substantial Completion of the entire
Third Expansion Premises, except to the extent expressly set forth in this
Section 6(b), any portion of the Third Expansion Tenant Improvement Allowance
that is not used before such date shall be deemed forfeited by Tenant without
any recourse to Landlord. Tenant shall have no right to receive a payout of any
unused Third Expansion Tenant Improvement Allowance, but it shall have the right
to credit not more than ten percent (10%) of any unused portion of the Third
Expansion Tenant Improvement Allowance toward Base Rent, provided Tenant (i) is
not otherwise in default pursuant to the terms of the Lease and (ii) provides
written notice to Landlord of Tenant’s desire to utilize such rent credit prior
to the earlier to occur of (1) May 1, 2018 and (2) ninety (90) days after the
Substantial Completion of the entire Third Expansion Premises, in which event
the rent credit shall be applied on the immediately following month and shall
continue until such rent credit has been applied in full. In the event Tenant
shall be entitled to a rent credit for the partial amount of Base Rent payable
with respect to any month, Tenant shall promptly pay the balance of the Base
Rent for such month in accordance with the terms of the Lease.

(c)    Changes to Space Plan. Neither Tenant nor Landlord shall make material
changes to the approved Space Plan or the work reflected in the approved Space
Plan without the written consent of the other party, which consent shall not be
unreasonably withheld, conditioned or delayed provided such changes do not
materially alter the ability of the Tenant to use the Third Expansion Premises
as intended, and do not increase the amount of the Excess Amount. Tenant shall
have the right, at Tenant’s sole cost and expense, to have its construction
representative at the Third Expansion Premises and the Initial Premises,
Expansion Premises and Second Expansion Premises at all times during the
construction of the Third Expansion Improvements to review and monitor the
performance of same; provided, however, Tenant’s construction representative
shall not interfere with or delay the construction of any portion of the Third
Expansion Improvements.

        (d)     Removal of Third Expansion Improvements. Except for items
addressed below, Tenant will have no obligation to remove its initial standard
office Leasehold Improvements at the expiration or earlier termination of the
Lease, which are approved by Landlord in advance at the time of Landlord’s
approval of the Space Plan or upon submission of future requests to alter the
Third Expansion Premises. Tenant agrees that all specialty equipment and
alterations, such as lab/computer/server rooms, supplemental HVAC,

5
        

--------------------------------------------------------------------------------

generators, UPS, staircases, raised floors, specialty conduits, private
bathrooms, shower rooms, Tenant specific, non-standard office buildout items,
and any alterations to the portions of the Third Expansion Premises which are
currently common areas (e.g. the lobby of the Building, common hallways and
common area bathrooms), shall be removed by Tenant at Landlord’s sole discretion
upon surrender; provided, however, with respect to the lobby, Tenant shall not
be obligated to restore the lobby of the Building to its original condition, but
Tenant shall be obligated to remove any moveable partitions, trade fixtures,
moveable equipment or furniture, including, without limitation, the reception
desk, at the expiration of earlier termination of the Lease. In any event,
Landlord hereby requires Tenant to remove any wiring and cabling installed by
Tenant, including, without limitation, the Third Expansion Improvement Systems
(as defined below). All unattached and moveable partitions, trade fixtures,
moveable equipment or furniture located in the Premises and acquired by or for
the account of Tenant which can be removed without material damage to the
Building or Premises, and all personal items brought into the Premises by Tenant
shall be owned by Tenant and will be removed by Tenant subject to and in
accordance with Paragraph 4.7 of the Original Lease, including but not limited
to all servers, server racks, generators, supplemental HVAC units, furniture,
phone and TV systems.

        (e)    Substantial Completion. Landlord shall cause the Substantial
Completion of each Phase I and Phase II of the Third Expansion Improvements.
Landlord and Tenant acknowledge and agree that Landlord may achieve or cause the
achievement of the Substantial Completion on a phased basis. For the purposes of
this Amendment, “Substantial Completion” shall mean (i) the completion of the
applicable Phase I or Phase II portion of the Third Expansion Improvements,
subject only to the Final Punchlist (as defined below) and other uncompleted
elements of construction, decoration, painting, millwork or other work and
mechanical adjustment, and (ii) the issuance of a certificate of occupancy (or
its equivalent) for the applicable Phase I or Phase II portion of the Third
Expansion Premises for the Permitted Use and a certification signed by the
Architect certifying that the applicable Phase I or Phase II portion of the
Third Expansion Improvements have been completed in accordance with the Space
Plan; provided, however, if Landlord is unable to obtain such certificate of
occupancy (or its reasonable equivalent) by virtue of the fact that Tenant has
not yet completed the installation of its Third Expansion Improvement Systems in
the applicable Phase I or Phase II portion of the Third Expansion Improvements
or for any other reason beyond the reasonable control of Landlord, then the
applicable Phase I or Phase II portion of the Third Expansion Improvements shall
be deemed Substantially Complete upon the certification of the Architect as
stated in subsection (i), above, notwithstanding anything to the contrary in the
foregoing.
(f)    Third Expansion Improvement Systems. Tenant shall substantially complete
the installation of Tenant’s data, telephone, audio-visual, internet and video
systems and Tenant’s furniture and furniture systems (collectively, the “Third
Expansion Improvement Systems”) in the Third Expansion Premises – Phase I and
the Third Expansion Premises – Phase II, as applicable, at Tenant’s expense.
Tenant shall be permitted to coordinate the installation of the Third Expansion
Improvement Systems at the same time as Landlord is coordinating the Third
Expansion Improvements as long as Tenant does not unreasonably interfere in any
way with the construction process (by causing disharmony of labor relations at
the Property, scheduling or coordination difficulties, etc.). In no event shall
the Third Expansion Improvements include any Third Expansion Improvement
Systems, the responsibility of which shall be Tenant’s. Tenant acknowledges that
the ability to obtain the certificate of occupancy for the applicable Phase I or
Phase II portion of the Third Expansion Premises depends upon the completion of
all or a portion of Third Expansion Improvement Systems. Prior to the Third
Expansion Commencement Date – Phase I or the Third Expansion Premises – Phase
II, as applicable, Tenant shall comply with and perform, and shall cause its
employees, agents, contractors, subcontractors, material suppliers and laborers
to comply with and perform, all of Tenant’s obligations under the Lease and this
Amendment. In all events, Tenant shall indemnify Landlord in the manner provided
in the Lease against any claim, loss or cost arising out of any interference
with, or damage to, the Third Expansion Improvements or any other work in the
Building, or any delay thereto, or any increase in the cost thereof on account
in whole or in part of any act, omission, neglect or default by Tenant or any
Tenant contractor.
(g)    Final Punchlist Items. Prior to Substantial Completion, Tenant shall
cause the Architect to inspect the applicable Phase I or Phase II portion of the
Third Expansion Improvements and prepare a list

6
        

--------------------------------------------------------------------------------

of the customary punchlist type items, and any items of a seasonal nature, then
remaining to be completed (the “Final Punchlist”) and Tenant shall cause such
Final Punchlist to be completed in a diligent manner. If Tenant has elected to
have Landlord manage the Third Expansion Improvements, then (i) the Final
Punchlist work shall take place during regular business hours, but in a manner
which will seek to minimize interruption of Tenant’s use and occupancy of the
Premises, (ii) Landlord shall endeavor to complete all punch list work within
thirty (30) days (or such longer period as is reasonably required with respect
to applicable items), other than matters that cannot be completed owing to their
seasonal nature, and subject to extension for Force Majeure and delays caused by
Tenant, and (iii) any disputed Final Punchlist items identified as such during
preparation of the Final Punchlist shall be completed by Landlord as aforesaid
within thirty (30) days, subject to Landlord’s right to dispute whether such
disputed items constitute a change to the applicable Phase I or Phase II portion
of the Third Expansion Improvements.
(h)    Commencement of Base Rent Payments. Except due to a Landlord Delay in
connection with the approval of the Space Plan and Third Expansion Plans and
Specifications, if the applicable Phase I or Phase II portion of the Third
Expansion Improvements have not been Substantially Completed by the Third
Expansion Premises Rent Commencement Date – Phase I or the Third Expansion
Premises Rent Commencement Date – Phase II, respectively, then Landlord shall
not be subject to any penalty, claim or liability nor shall the validity of this
Lease or the obligations of Tenant hereunder be in any way affected and Tenant
shall be obligated to commence paying Base Rent for the Phase I or Phase II
portion, as applicable. In no event shall Tenant occupy the Third Expansion
Premises – Phase II prior to March 1, 2018.

(i)    Additional Rent Prior to Base Rent Commencement. At all times between the
Third Expansion Commencement Date – Phase I and the Third Expansion Rent
Commencement Date – Phase II, Tenant shall be responsible for direct payment of
electricity, any other separately metered utilities, and any other Additional
Rent due and payable with respect to Third Expansion Premises – Phase I. In no
event shall Tenant be permitted to occupy the Third Expansion Premises – Phase
II prior to the Third Expansion Commencement Date – Phase II, and, as such,
shall not be responsible for the payment of electricity, any other separately
metered utilities, and any other Additional Rent due and payable with respect to
Third Expansion Premises – Phase II until the Third Expansion Commencement Date
– Phase II.

(j)    Intentionally deleted.

(k)    Landlord’s Capital Improvements in Office Park. Landlord shall use
commercially reasonable efforts in connection with the construction of the Third
Expansion Improvements, the Road Construction and the Parking Configuration to
not unreasonably interfere with Tenant’s on-going operations at the Premises,
including parking, ingress and egress. Tenant acknowledges that noise,
vibrations, disturbance, relocation of Building access, and the temporary
relocation of parking, ingress and egress shall not entitle Tenant to any rent
abatement or to terminate this Lease. Except as otherwise expressly provided in
the Lease, Landlord shall have no liability to Tenant nor shall Tenant’s
obligations under this Lease be reduced or abated in any manner whatsoever by
reason of any inconvenience, annoyance, interruption or injury to business
arising from the Third Expansion Improvements, the Road Construction and the
Parking Configuration.

7.    Operating Costs; Property Taxes; Base Year. For any period during the

1,000 rentable square feet of the Premises to 3.5 stalls per 1,000 rentable
square feet of the Premises. The definition of Parking Ratio shall be amended to
replace “4.0” with “3.5”. Notwithstanding the foregoing, Tenant shall have a
minimum of 427 parking spaces.

9.    Road Construction; Parking Configuration. Tenant hereby acknowledges that
Landlord intends to create a second access point for ingress to Burlington
Centre office park and reconfigure the existing parking in the 10 Corporate
Drive parking area, in the locations set forth on the plan attached as Fifth
Amendment – Exhibit B (the “New Road and Parking Plan”). Landlord shall have the
right to construct the New Road and, in doing so, may remove fifty-two (52)
parking spaces from the 10 Corporate Drive parking area, which such parking
spaces shall be replaced as set forth in the New Road and Parking Plan. Tenant
acknowledges that noise, disturbance, relocation of Building access, and the
temporary disruption parking shall not entitle Tenant to any rent abatement or
to terminate this Lease, provided Tenant at all times has access to and from the
Building and Landlord maintains Tenant’s parking allocation (as the same may be
reduced pursuant to Section 8 of this Amendment). Except as otherwise expressly
provided in the Lease, Landlord shall have no liability to Tenant nor shall
Tenant’s obligations under this Lease be reduced or abated in any manner
whatsoever by reason of any inconvenience or annoyance arising from Landlord’s
capital projects. Landlord shall use reasonable efforts to minimize any
interference with Tenant’s business in the Premises due to Landlord completing
the New Road. Tenant’s final 427 parking spaces shall be located as set forth on
the Fifth Amendment – Exhibit A.

10.    Brokers. Tenant was represented in the transaction evidenced by this
Amendment by Jones Lane LaSalle, a licensed real estate broker. Landlord was
represented in the transaction evidenced by this Amendment by CB Richard Ellis –
N.E. Partners, LP, a licensed real estate broker and certain representatives of
Landlord. Landlord and Tenant warrant to each other that they have had no
dealings with any broker, agent or finder in connection with this Amendment
except as set forth above. Landlord shall be responsible for paying any
commission or fee owed to Landlord’s broker, CB Richard Ellis – N.E. Partners,
LP, in connection with this Amendment and Landlord shall be responsible for the
payment of any commission or fee owed to Jones Lang LaSalle in connection with
this Amendment pursuant to a separate written agreement. Each party hereto
agrees to protect, indemnify and hold harmless the other from and against any
and all expenses with respect to any compensation, commissions and charges
claimed by any other broker, agent or finder not identified above with respect
to this Amendment or the negotiation thereof that is made by reason of any
action or agreement by such party.

11.    Lease Ratification. This instrument and all of the terms and provisions
hereof shall be considered for all purposes to be incorporated into and made

therein is hereby ratified and confirmed, and, as modified hereby, shall
continue in full force and effect. All references appearing in the Original
Lease and in any related instruments shall be amended and read hereafter to be

terminated or assigned.

12.    Independence of Covenants. Landlord’s and Tenant’s covenants in the Lease
are independent and, without limiting the generality of the foregoing, Tenant
acknowledges that its covenant to pay Base Rent and Additional Rent is
independent of Landlord’s obligations under the Lease, and that in the event
that Tenant shall have a claim against Landlord, Tenant shall not have the right
to deduct the amount allegedly owed to Tenant from any Base Rent or Additional
Rent due under the Lease, it being understood that Tenant’s sole remedy for
recovering upon such claim shall be to bring an independent legal action against
Landlord.

13.    Authority. Each party represents and warrants to the other that such
party and the person signing on its behalf are duly authorized to execute and
deliver this Amendment and that this Amendment constitutes its legal, valid and
binding obligation.

14.    Counterparts; Electronic Signatures.  This Lease may be executed in
counterparts, including both counterparts that are executed on paper and
counterparts that are in the form of electronic records and are executed
electronically.  An electronic signature means any electronic sound, symbol or
process attached to or logically associated with a record and executed and
adopted by a party with the intent to sign such record, including facsimile or
e-mail electronic signatures.  All executed counterparts shall constitute one
agreement, and each counterpart shall be deemed an original.  The parties hereby
acknowledge and agree that electronic records and electronic signatures, as well
as facsimile signatures, may be used in connection with the execution of this
Lease and electronic signatures, facsimile signatures or signatures transmitted
by electronic mail in so-called pdf format shall be legal and binding and shall
have the same full force and effect as if an a paper original of this Lease had
been delivered had been signed using a handwritten signature.  Landlord and
Tenant (i) agree that an electronic signature, whether digital or encrypted, of
a party to this Lease is intended to authenticate this writing and to have the
same force and effect as a manual signature, (ii) intend to be bound by the
signatures (whether original, faxed or electronic) on any document sent or

the Electronic Signatures in Global and National Commerce Act (“E-SIGN”), and
Uniform Electronic Transactions Act (“UETA”), that a signature by fax, email or
other electronic means shall constitute an Electronic Signature to an Electronic
Record under both E-SIGN and UETA with respect to this specific transaction.

15.     Governing Law. This Lease and the rights and obligations of the parties
hereunder shall be construed and enforced in accordance with the laws of the
Commonwealth of Massachusetts.

16.    Effective Date. 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. This Amendment shall become effective and binding only
upon execution and delivery of this Amendment by all of the parties hereto and
approval by Landlord's lender.

17.    Option to Renew. Tenant’s existing Option to Renew shall be modified to
allow Tenant to exercise its Option with respect to the entire Premises,
including the Third Expansion Premises, or any portion of the Premises leased by
Tenant at such time, provided Tenant has not assigned or subleased more than
twenty-five percent (25%) of the entire Premises (i.e. the entire 114,807
rentable square foot Premises).
