|2. | Lease Grant.
|-- | ------------

The Premises are hereby leased to
Tenant from Landlord, together with the right to use any portions of the Complex that are from time to time designated by Landlord for the common use of tenants and others, including, but not limited to (i) the common stairways and access ways,
lobbies, hallways, entrances, stairs, elevators and any passageways thereto, toilets, refuse facilities, common pipes, ducts, conduits, wires, and other areas or facilities within the Building for the general use, convenience and benefit of Tenant

thereof, as well as in or to the street entrances, halls, passages, elevators, stairways and other improvements thereof, as Landlord may deem necessary or desirable, so long as the same does not materially adversely affect Tenants access to or
use of the Premises and Landlord takes commercially reasonable efforts to minimize any disruption to Tenant caused by such changes. The Tenant shall also have the right to use the telephone and electrical closets and appurtenant equipment which
serve the Premises and other premises in the Building; provided the right to access such closets and equipment shall be under the supervision of the Landlord and upon such rules and regulations as the Landlord shall designate, including approval of
any vendors which may require access to connect the equipment servicing the Tenants Premises. Landlord may adopt any name for the Building and/or Complex and Landlord reserves the right to change the name or address of the Building at any

Execution Version



Landlord and Tenant acknowledge that the Premises are in a Building and Complex which are not open to
the general public. Access to the Building or Complex is restricted to Landlord, Tenant, their agents, employees and contractors and to their invited visitors. In the event of a labor dispute including a strike, picketing, informational or
associational activities directed at Tenant or any other tenant, Landlord reserves the right unilaterally to alter Tenants ingress and egress to the Building or Complex or make any other change in operating conditions to restrict pedestrian,
vehicular or delivery ingress and egress to a particular location. The foregoing notwithstanding, Tenant shall have access to and use of the Premises twenty-four (24) hours per day and three hundred sixty-five (365) days per year.



|3. | Adjustment of Commencement Date; Possession.
|-- | --------------------------------------------

3.01
The Landlord shall deliver the Premises with Landlords Work Substantially Complete (as defined in Exhibit C) on August 15, 2009 to Tenant. In the event Landlord delivers the Premises to Tenant Substantially Complete prior to
August 15, 2009, Tenant shall have early use of the Premises commencing on such delivery date for all purposes including moving in, installation of technology, furniture and trade fixtures, as well as for the Permitted Use, but the Commencement
Date shall nonetheless be August 15, 2009. If for any reason whatsoever, Landlord is unable to deliver possession of the Premises to Tenant with the Landlords Work Substantially Complete on or prior to August 15, 2009, then this
Lease shall remain in full force and effect and the Commencement Date shall automatically be adjusted forward on a day-for-day basis until the date on which Landlord delivers possession of the Premises to Tenant with the Landlords Work
Substantially Complete. In the event Landlord does not deliver the Premises to Tenant Substantially Complete by September 15, 2009, as such date is extended due to Force Majeure and Tenant Delay (as defined in Exhibit C) (the Late
Delivery Threshold), then each day of delay after the Late Delivery Threshold shall result in an increase in the Base Rent abatement set forth in Section 1.03 of one day (by way of example only, if there is no Force Majeure and no
Tenant Delay and Landlord delivers the Premises Substantially Complete on September 17, 2009, the Base Rent abatement period shall be 92 days instead of 90 days). In the event Landlord fails, for any reason other than Force Majeure, to deliver
possession of the Premises as required by this Lease on or before November 15, 2009 (which date shall be extended for each day of Tenant Delay), then Tenant may elect, upon notice to Landlord, given any time prior to the date of such delivery,
to terminate this Lease effective upon the date that is thirty (30) days following such notice; provided that if Landlord delivers possession of the Premises prior to the end of such 30-day period, then such termination shall be of no force or
effect. In the event Landlord fails, due to Force Majeure alone, to deliver possession of the Premises as required by this Lease on or before December 15, 2009 (which date shall be extended for each day of Tenant Delay), then Tenant may elect,
upon notice to Landlord, given any time prior to the date of such delivery, to terminate this Lease effective upon the date that is thirty (30) days following such notice; provided that if Landlord delivers possession of the Premises prior to
the end of such 30-day period, then such termination shall be of no force or effect.

3.02 Subject to Landlords obligations under
this Lease, including the obligation to perform Landlords Work, the Premises are accepted by Tenant in as is condition and configuration without any representations or warranties by Landlord express or implied except as expressly
provided in this Lease. By taking possession of the Premises, Tenant agrees that the



5

Execution Version



Premises are in good order and satisfactory condition; provided, this shall not limit the Landlords obligations under the provisions of this Lease
including, without limitation, Section 7 (Building Services) and Section 9.02. Landlord shall also be obligated to cure any violations of laws with respect to the Premises (including the Americans with Disabilities Act) which may exist as
of the Commencement Date, if any, within a reasonable period of time after the Landlord becomes aware of same. In the event Landlords Work triggers any necessary additional work to the Premises, Building or Complex to comply with any laws
(including the Americans with Disabilities Act), Landlord shall be solely responsible for completing such additional work at Landlords sole cost and expense. Except as set forth in Section 3.01, Landlord shall not be liable for a failure
to deliver possession of the Premises, or any other space, due to the holdover or unlawful possession of such space by another party; provided, however, that Landlord shall use reasonable efforts to obtain possession of the space. If Tenant takes
possession of the Premises, or any portion thereof, before the Commencement Date, such possession shall be subject to the terms and conditions of this Lease. However, except for the cost of services requested by Tenant, Tenant shall not be required
to pay Rent for any days of possession before the Commencement Date.



|4. | Rent.
|-- | -----

4.01 Tenant shall pay Landlord, without any
setoff or deduction, unless expressly set forth in this Lease, all Base Rent and Additional Rent due for the Term (collectively referred to as Rent). Additional Rent means all sums (exclusive of Base Rent) that
Tenant is required to pay Landlord under this Lease. Tenant shall pay and be liable for all rental, sales and use taxes (but excluding income taxes), if any, imposed upon or measured by Rent. Base Rent and recurring monthly charges of Additional
Rent shall be due and payable in advance on the first day of each calendar month without notice or demand. All other items of Rent shall be due and payable by Tenant on or before 30 days after billing by Landlord. Rent shall be made payable to the
entity, and sent to the address, Landlord designates and shall be made by good and sufficient check or by other means acceptable to Landlord. Past due Rent shall accrue interest at 12% per annum from the due date until actually paid. The
foregoing notwithstanding, Tenant shall not be responsible for payment of such interest for the first such late payment in any calendar year if such late payment is made within five (5) days of receipt of Landlords written notice of
delinquency. Landlords acceptance of less than the correct amount of Rent shall be considered a payment on account of the earliest Rent due. Rent for any partial month during the Term shall be prorated. No endorsement or statement on a check
or letter accompanying payment shall be considered an accord and satisfaction. Tenants covenant to pay Rent is independent of every other covenant in this Lease.

4.02 Tenant shall pay Tenants Pro Rata Share of Taxes and Expenses in accordance with Exhibit B of this Lease.



|5. | Compliance with Laws; Use.

configuration and occupancy of the Premises, but only to the extent such obligations are triggered by Tenants particular manner of use of the Premises,
other than for general office use. In addition, Tenant shall, at its sole cost and expense, promptly comply with any Laws that relate to the Base Building (defined below), but only to the extent such obligations are triggered by
Tenants particular manner of use of the Premises, other than for general office use, or Alterations or improvements in the Premises performed or requested by Tenant, specifically excluding Landlords Work. Base Building
shall include the structural portions of the Building, the public restrooms and the Building mechanical, electrical and plumbing systems and equipment located in the internal core of the Building on the floor or floors on which the Premises are
located. Tenant shall promptly provide Landlord with copies of any notices it receives regarding an alleged violation of Law. Tenant shall comply with the rules and regulations of the Building attached as Exhibit E and such other
reasonable rules and regulations adopted by Landlord from time to time, including rules and regulations for the performance of Alterations (defined in Section 9). Landlord will deliver the Premises in compliance with all applicable laws
(including the Americans with Disabilities Act) as of the Commencement Date.



|6. | Security Deposit.
|-- | -----------------

The Security Deposit shall be
delivered to Landlord within five (5) business days of execution of this Lease by Tenant and held by Landlord without liability for interest (unless required by Law) as security for the performance of Tenants obligations. The Security
Deposit is not an advance payment of Rent or a measure of damages. Landlord may use all or a portion of the Security Deposit to satisfy past due Rent or to cure any Default (defined in Section 18) by Tenant. If Landlord uses any portion of the
Security Deposit, Tenant shall, within 5 days after demand, restore the Security Deposit to its original amount. Subject to the Landlords right to apply the Security Deposit as set forth herein, Landlord shall return any unapplied portion of
the Security Deposit to Tenant within 45 days after the later to occur of the Termination Date or the date Tenant surrenders the Premises to Landlord in compliance with Section 25. Landlord may assign the Security Deposit to a successor or
transferee and, following the assignment, Landlord shall have no further liability for the return of the Security Deposit. Landlord shall not be required to keep the Security Deposit separate from its other accounts.

The Security Deposit shall be in the form of an irrevocable letter of credit (the Letter of Credit), which Letter of Credit shall:
(a) be in the initial amount of $135,680; (b) be issued on the form attached hereto as Exhibit G; (c) name Landlord as its beneficiary; and (d) be drawn on an FDIC insured financial institution reasonably satisfactory
to the Landlord. The Letter of Credit (and any renewals or replacements thereof) shall be for a term of not less than 1 year. Tenant agrees that it shall from time to time, as necessary, whether as a result of a draw on the Letter of Credit by
Landlord pursuant to the terms hereof or as a result of the expiration of the Letter of Credit then in effect, renew or replace the original and any subsequent Letter of Credit so that a Letter of Credit, in the amount required hereunder, is in
effect until a date which is at least 60 days after the Termination Date of the Lease. If Tenant fails to furnish such renewal or replacement at least 60 days prior to the stated expiration date of the Letter of Credit then held by Landlord,
Landlord may draw upon such Letter of Credit and hold the proceeds thereof (and such proceeds need not be segregated) as a Security Deposit pursuant to the terms of this Section 6. Any renewal or replacement of the original or any subsequent
Letter of Credit shall meet the requirements for the original Letter of Credit as set forth above, except that such replacement or renewal shall be issued by an FDIC insured financial institution satisfactory to Landlord at the time of the issuance
thereof.

Execution Version



If Landlord draws on the Letter of Credit as permitted in this Lease, then, upon demand of Landlord,
Tenant shall restore the amount available under the Letter of Credit to its original amount by providing Landlord with an amendment to the Letter of Credit evidencing that the amount available under the Letter of Credit has been restored to its
original amount.



|7. | Building Services.
|-- | ------------------

7.01 Landlord shall furnish
Tenant with the following services: (a) water for use in the Base Building lavatories; (b) customary heat and air conditioning in season during Building Service Hours; provided that Tenant shall have the right to receive HVAC service for
the Premises during hours other than Building Service Hours by paying Landlords then standard charge for additional HVAC service so long as Tenant requests same by written notice to Landlord not later than 12:00 noon on the Business Day
preceding the day of such overtime usage; (c) standard janitorial service on Business Days; (d) Elevator service; (e) Electricity in accordance with the terms and conditions in Section 7.02; and (f) such other services as
Landlord reasonably determines are necessary or appropriate for the Building or Complex. Tenant may continuously run supplemental cooling of its server room in the Premises 24 hours per day, 365 days per year (Supplemental Cooling).
Supplemental Cooling is not a Landlord-provided service, Landlord shall not shut down the Supplemental Cooling in non-Building Service Hours, and Landlord shall not charge Tenant the off-hours HVAC charges for Supplemental Cooling as same will be
subject to electricity charges for Supplemental Cooling as part of the Premises electricity submeter, the charges for which shall be paid solely by the Tenant.

7.02 (a) Electricity shall be distributed to the Premises either by the electric utility company selected by Landlord to provide electricity service for the Building and/or Complex, or, at Landlords option, by
Landlord; and Landlord shall permit Landlords wires and conduits, to the extent available, suitable and safely capable, to be used for such distribution. If and so long as Landlord is distributing electricity to the Premises, Tenant shall
obtain all of its electricity from Landlord. Such charges will be based on Landlords actual cost of such electrical service based upon the existing submeter measuring usage in the Premises. If the electric utility company selected by Landlord
to provide electricity service for the Building and/or the Complex is distributing electricity to the Premises, Landlord may elect to require Tenant, at its cost, to make all necessary arrangements with such electric utility company for metering and
paying for electric current furnished to the Premises. All electricity used during the performance of janitorial service, or the making of any alterations or repairs in or to the Premises (excluding the Landlords Work), or the operation of any
special air conditioning system serving the Premises, including Supplemental Cooling, shall be paid by Tenant. Landlord shall as part of the Landlords Work install a meter or sub-meter for electricity used in the Premises.

Landlord reserves the right at any time and from time to time before or during the Term to contract with an electric service provider (Electric
Service Provider) of its choice to provide electricity service for the Building. Tenant shall cooperate with Landlord and the Electric Service Provider at all times and, as reasonably necessary, shall allow Landlord and the Electric
Service Provider reasonable access after reasonable notice except in an emergency where Landlord shall provide notice to the extent reasonably possible to the Buildings and Complexs electric lines, feeders, risers, wiring and other
machinery within the Premises.

Execution Version



(b) Without the consent of Landlord, Tenants use of electrical service shall not exceed, either
in voltage, rated capacity, use beyond Building Service Hours or overall load, that which Landlord, on a rentable square foot basis, reasonably deems to be standard for the Building, which as of the date of this Lease is five (5) watts per
rentable square foot. Landlord acknowledges that Tenants operation of the Supplemental Cooling generally as well as beyond Building Service Hours (including 24 hours per day, seven days per week), using the existing unit to be delivered with
the Premises, does not currently exceed the limits set forth in or otherwise violate the preceding sentence. Landlord shall have the right to measure electrical usage by commonly accepted methods. If it is determined that Tenant is using excess
electricity, Tenant shall pay Landlord for the cost of such excess electrical usage as Additional Rent.

7.03 Landlords failure to
furnish, or any interruption, diminishment or termination of services due to the application of Laws, the failure of any equipment, the performance of repairs, improvements or alterations, utility interruptions or the occurrence of an event of Force
Majeure (defined in Section 26.03) (collectively a Service Failure) shall not render Landlord liable to Tenant, constitute a constructive eviction of Tenant, give rise to an abatement of Rent, nor relieve Tenant from the
obligation to fulfill any covenant or agreement. Notwithstanding the foregoing, in the event a Service Failure that is within the reasonable control of Landlord continues for a period in excess of five (5) consecutive business days,
Tenants Base Rent shall abate on a day-by-day basis in proportion to the portion of the Premises that Tenant is unable to use for the Permitted Use. The foregoing Base Rent abatement shall be the Tenants sole remedy for any interruption
of Tenants business operations due to such Service Failure.



|8. | Leasehold Improvements.
|-- | -----------------------

All improvements in and to
the Premises, including any Alterations (collectively, Leasehold Improvements) shall remain upon the Premises at the end of the Term without compensation to Tenant. Landlord, however, by written notice to Tenant given at the time
of Landlords consent to any Alterations, to the extent required, may require Tenant, at its expense, to remove any Alterations (other than Landlords Work) that, in Landlords reasonable judgment, are of a nature that would require
removal and repair costs that are materially in excess of the removal and repair costs associated with standard office improvements and all Cable (as defined in Section 9.01; collectively referred to as Required Removables).
Required Removables shall include, without limitation, Cable, internal stairways, raised floors, personal restrooms and showers, vaults, rolling file systems and structural alterations and modifications, but shall not include Landlords Work or
any other improvements in the Premises on the date that possession of the Premises is delivered to Tenant. The designated Required Removables shall be removed by Tenant before the Termination Date. Tenant shall repair damage caused by the
installation or removal of Required Removables. If Tenant fails to perform its obligations in a timely manner, Landlord may perform such work at Tenants expense.

|9. | Repairs and Alterations.
|-- | ------------------------

9.01 Tenant shall
periodically inspect the Premises to identify any conditions that are dangerous or in need of maintenance or repair. Tenant shall promptly provide Landlord with notice of any such conditions. Tenant shall, at its sole cost and expense, perform all
maintenance and repairs to the Premises that are not Landlords express responsibility under this Lease, and keep the Premises in good condition and repair, reasonable wear and tear excepted. Tenants repair and maintenance obligations
include, without limitation, repairs to: (a) floor covering; (b) interior partitions; (c) doors; (d) the interior side of demising walls; (e) electronic, phone and data cabling and related equipment that is installed by or

(h) Rooftop Equipment (defined in Section 28 below). To the extent Landlord is not reimbursed by insurance proceeds, Tenant shall reimburse Landlord for the cost of repairing damage to the Building caused by the acts of Tenant, Tenant
Related Parties and their respective contractors and vendors (including without limitation repairs necessitated by the installation, use, maintenance, repair and removal of the Rooftop Equipment). If Tenant fails to commence to make any repairs to
the Premises for more than 15 days after notice from Landlord (although notice shall not be required in an emergency) and to continuously and diligently proceed to complete the repair if same cannot be completed within said 15 day period, Landlord
may make the repairs, and Tenant shall pay the reasonable cost of the repairs, together with an administrative charge in an amount equal to 10% of the cost of the repairs. Tenant Related Parties shall mean Tenants officers,
directors, shareholders, employees and agents.

9.02 Landlord shall keep and maintain in good repair and working order and perform
maintenance upon the: (a) structural elements of the Building; (b) mechanical (including HVAC), electrical, plumbing and fire/life safety systems serving the Building in general; (c) Common Areas; (d) roof of the Building;
(e) exterior windows of the Building; and (f) elevators serving the Building. Landlord shall promptly make repairs for which Landlord is responsible.

9.03 Tenant shall not make alterations, repairs, additions or improvements or install any Cable (collectively referred to as Alterations) without first obtaining the written consent of Landlord in
each instance, such consent to include review and approval of all plans for such Alterations, which consent shall not to be unreasonably withheld, conditioned or delayed except that Landlord shall have complete discretion with regard to granting or
withholding approval of the portions of the proposed Alterations to the extent such Alterations would impact the Buildings structure or systems, or would be visible from the common facilities or exterior of the Building. However,
Landlords consent shall not be required for any Alteration that satisfies all of the following criteria (a Cosmetic Alteration): (a) is of a cosmetic nature such as painting, wallpapering, hanging pictures and
installing carpeting; (b) is not visible from the exterior of the Premises or Building; (c) will not affect the Base Building; (d) does not require work to be performed inside the walls, below the floor, or above the ceiling of the
Premises; and (e) the cost of such work does not exceed $30,000.00. Tenant shall provide written notice to Landlord prior to the commencement of any Cosmetic Alterations and shall deliver to Landlord a copy of the plans and specifications, if
any, for Cosmetic Alterations. Cosmetic Alterations shall be subject to all the other provisions of this Section 9.03.Prior to starting work, Tenant shall furnish Landlord with plans and specifications; names of contractors reasonably
acceptable to Landlord

Execution Version



(provided that Landlord may designate specific contractors with respect to Base Building); required permits and approvals; evidence of contractors and
subcontractors insurance in amounts reasonably required by Landlord and naming Landlord as an additional insured; and any security for performance in amounts reasonably required by Landlord. Changes to the plans and specifications must also be
submitted to Landlord for its approval. Alterations shall be constructed in a good and workmanlike manner using materials of a quality reasonably approved by Landlord. Tenant shall reimburse Landlord for any sums paid by Landlord for third party
examination of Tenants plans for non-Cosmetic Alterations. In addition, Tenant shall pay Landlord a fee for Landlords oversight and coordination of any Alterations other than Cosmetic Alterations equal to 3% of the cost of the
Alterations. Upon completion, Tenant shall furnish as-built plans for all Alterations other than Cosmetic Alterations, completion affidavits and full and final waivers of lien. Landlords approval of an Alteration shall not be
deemed a representation by Landlord that the Alteration complies with Law.



|10. | Entry by Landlord.
|--- | ------------------

Landlord may enter the Premises
to inspect, show to prospective buyers of the Building or prospective lenders, or clean the Premises or to perform or facilitate the performance of repairs, alterations or additions to the Premises or any portion of the Building or in the last
twelve (12) months of the Term, show to prospective tenants. Except in emergencies or to provide Building services, Landlord shall provide Tenant with reasonable prior verbal notice of entry, shall provide Tenant with the opportunity to
accompany Landlord, and shall use reasonable efforts to minimize any interference with Tenants use of the Premises. If reasonably necessary, Landlord may temporarily close all or a portion of the Premises to perform repairs, alterations and
additions. However, except in emergencies, Landlord will not close the Premises if the work can reasonably be completed on weekends and after Building Service Hours. Entry by Landlord shall not constitute a constructive eviction or entitle Tenant to
an abatement or reduction of Rent. In connection with any repairs made in the Premises by Landlord, Landlord shall not eliminate power to the Supplemental Cooling or, if unavoidable, Landlord shall bring in temporary power or cooling equipment at
Landlords sole cost and expense.



|11. | Assignment and Subletting.
|--- | --------------------------

11.01 Except in
connection with a Permitted Transfer (defined in Section 11.04), Tenant shall not assign, sublease, transfer or encumber any interest in this Lease or allow any third party to use any portion of the Premises (collectively or individually, a
Transfer) without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed if Landlord does not exercise its recapture rights under Section 11.02. If the entity which
controls the voting shares/rights of Tenant changes at any time, such change of ownership or control shall constitute a Transfer, subject to Tenants rights with respect to a Permitted Transfer as set forth in Section 11.04, unless Tenant
is an entity whose outstanding stock is listed on a recognized securities exchange or if at least 80% of its voting stock is owned by another entity, the voting stock of which is so listed. Any attempted Transfer in violation of this Section is
voidable by Landlord. In no event shall any Transfer, including a Permitted Transfer, release or relieve Tenant from any obligation under this Lease.

Execution Version



11.02 Tenant shall provide Landlord with financial statements for the proposed transferee, a fully
executed copy of the proposed assignment, sublease or other Transfer documentation and such other information as Landlord may reasonably request. Within 15 Business Days after receipt of the required information and documentation, Landlord shall
either: (a) consent to the Transfer by execution of a consent agreement in a form reasonably designated by Landlord; (b) reasonably refuse to consent to the Transfer in writing; or (c) recapture the portion of the Premises that Tenant
is proposing to Transfer for the term of the proposed Transfer. Landlord shall not exercise this right of recapture in the event the proposed Transfer would result, in the aggregate with any previous Transfers, in Transfers of less than forty
percent (40%) of the Premises. If Landlord exercises its right to recapture, this Lease shall automatically be amended (or terminated if the entire Premises is being assigned or sublet) to delete the applicable portion of the Premises effective
on the proposed effective date of the Transfer for the term of the proposed Transfer. Tenant shall pay Landlord its actual out-of-pocket fees, not to exceed $1,500.00, for Landlords review of any requested Transfer, excluding a Permitted
Transfer, for which Tenant will have no cost reimbursement obligation.

11.03 Tenant shall pay Landlord 50% of all rent and other
consideration which Tenant receives as a result of a Transfer that is in excess of the Rent payable to Landlord for the portion of the Premises and Term covered by the Transfer. Tenant shall pay Landlord for Landlords share of the excess
within 30 days after Tenants receipt of the excess. Tenant may deduct from the excess, on a straight-line basis, all reasonable and customary expenses directly incurred by Tenant attributable to the Transfer, including but not limited to
leasing concessions, brokers fees, attorneys fees and tenant improvements. If Tenant is in Default, Landlord may require that all sublease payments be made directly to Landlord, in which case Tenant shall receive a credit against Rent in
the amount of Tenants share of payments received by Landlord.

11.04 Tenant may assign this Lease to a successor to Tenant by
purchase, merger, consolidation or reorganization (an Ownership Change) or assign this Lease or sublet all or a portion of the Premises to an Affiliate without the consent of Landlord, provided that all of the following conditions
are satisfied (a Permitted Transfer): (a) Tenant is not in Default; (b) in the event of an Ownership Change, Tenants successor shall own substantially all of the assets of Tenant and have a net worth which is at
least equal to Tenants net worth as of the day prior to the proposed Ownership Change; (c) the Permitted Use does not allow the Premises to be used for retail purposes; and (d) Tenant shall give Landlord written notice at least 15
Business Days prior to the effective date of the Permitted Transfer. Tenants notice to Landlord shall include information and documentation evidencing the Permitted Transfer and showing that each of the above conditions has been satisfied. If
requested by Landlord, Tenants successor shall sign a commercially reasonable form of assumption agreement. Affiliate shall mean an entity controlled by, controlling or under common control with Tenant (for such period of
time as such entity continues to be controlled by, controlling or under common control with Tenant, it being agreed that the subsequent sale or transfer of stock resulting in a change in voting control, or any other transaction(s) having the overall
effect that such entity ceases to be controlled by, controlling or under common control with Tenant within twelve (12) months following an assignment of this Lease to an Affiliate, shall be treated as if such sale or transfer or transaction(s)
were, for all purposes, an assignment of this Lease governed by the provisions of this Article 11).

|12. | Liens.
|--- | ------

Tenant shall not permit mechanics or
other liens to be placed upon the Complex, Building, Premises or Tenants leasehold interest in connection with any work or service done or purportedly done by or for the benefit of Tenant or its transferees. Tenant shall give Landlord notice
at least 15 days prior to the commencement of any work in the Premises to afford Landlord the opportunity, where applicable, to post and record notices of non-responsibility. Tenant, within 10 days of notice from Landlord, shall fully discharge any
lien by settlement, by bonding or by insuring over the lien in the manner prescribed by the applicable lien Law. If Tenant fails to do so, Landlord may bond, insure over or otherwise discharge the lien. Tenant shall reimburse Landlord for any amount
paid by Landlord, including, without limitation, reasonable attorneys fees. Landlord shall have the right to require Tenant to post a performance or payment bond in connection with any work or service done or purportedly done by or for the
benefit of Tenant. Tenant acknowledges and agrees that all such work or service is being performed for the sole benefit of Tenant and not for the benefit of Landlord.



|13. | Indemnity and Waiver of Claims.
|--- | -------------------------------

Subject to the
provisions of Section 15 and except as specifically otherwise provided in this Lease and except for the negligence or intentional misconduct of Landlord or Landlord Related Parties (defined below), Tenant hereby waives all claims against and

failure of any security services, personnel or equipment, or (e) any matter not within the reasonable control of Landlord. In addition to the foregoing, except for the negligence or intentional misconduct of Landlord or Landlord Related
Parties, Tenant agrees that Landlord shall have no responsibility or liability whatsoever for any loss or damage, however caused, to furnishings, fixtures, equipment, or other personal property of Tenant or of any persons claiming by, through, or
under Tenant. Except to the extent caused by the negligence or willful misconduct of Landlord or any Landlord Related Parties, Tenant shall indemnify, defend and hold Landlord and Landlord Related Parties harmless against and from all liabilities,

negligence or intentional misconduct (including violations of Law) of Tenant, the Tenant Related Parties or any of Tenants transferees, contractors or licensees.

13.02 Subject to the provisions of Section 15, and except as specifically otherwise provided in this Lease, and except for the negligence or intentional misconduct of the Tenant (or those claiming under the
Tenant), Landlord shall indemnify, defend and hold Tenant harmless against and from all Losses which may be imposed upon, incurred by or asserted against Tenant by any third party arising out of or in connection with damage or injury occurring in

|16. | Casualty Damage.
|--- | ----------------

16.01 If all or any portion of
the Premises becomes untenantable by fire or other casualty to the Premises (collectively a Casualty), Landlord, with reasonable promptness but not later than sixty (60) days from the date of such casualty, shall cause a
general contractor selected by Landlord to provide Landlord and Tenant with a written estimate of the amount of time required using standard working methods to Substantially Complete the repair and restoration of the Premises and any Common Areas
necessary to provide access to the Premises (Completion Estimate). If the Completion Estimate indicates that the Premises or any Common Areas necessary to provide access to the Premises cannot reasonably be substantially completed
within 270 days from the date of the Casualty, then either party shall have the right to terminate this Lease upon written notice to the other within 10 days after receipt of the Completion Estimate. Tenant, however, shall not have the right to
terminate this Lease if the Casualty was caused by the gross negligence or intentional misconduct of Tenant or any Tenant Related Parties. In addition, Landlord, by notice to Tenant within 90 days after the date of the Casualty, shall have the right
to terminate this Lease if: (1) the Premises have been materially damaged and there is less than two (2) years of the Term remaining on the date of the Casualty; (2) any Mortgagee requires that the insurance proceeds be applied to the
payment of the mortgage debt; or (3) a material uninsured loss to the Building occurs. In addition, in the event that the Premises and the Common Areas are not Substantially Completed within 270 days from the date the Casualty occurred, subject
to reasonable delays (not to exceed sixty (60) days) for insurance adjustment or other matters beyond Landlords reasonable control, Tenant shall have the right to terminate this Lease upon 30 days advance notice to the Landlord given at
any time subsequent to 270 days (plus a period of up to sixty (60) days set forth above, if applicable) after the date of the Casualty but prior to such Substantial Completion; provided that if the Landlord delivers the Premises and the Common
Areas Substantially Complete prior to the expiration of such 30-day period then said notice of termination shall be of no force or effect.

16.02 If this Lease is not terminated, Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlords reasonable control, restore the Premises and Common Areas. Such
restoration shall be to substantially the same condition that existed on the Commencement Date, except for modifications required by Law or any other modifications to the Common Areas deemed desirable by Landlord. Upon notice from Landlord, Tenant

may agree to restore (exclusive of Landlords Work which shall be insured by Landlord); provided if the estimated cost to repair such Leasehold Improvements exceeds the amount of insurance proceeds received by Landlord from Tenants
insurance carrier, the excess cost of such repairs shall be paid by Tenant to Landlord prior to Landlords commencement of repairs. Landlord shall not be liable for any inconvenience to Tenant, or injury to Tenants business resulting in
any way from the Casualty or the repair thereof. Provided that Tenant is not in Default, during any period of time that all or a material portion of the Premises is rendered untenantable as a result of a Casualty, the Rent shall abate for the

|17. | Condemnation.
|--- | -------------

Either party may terminate this
Lease if any material part of the Building or any portion of the Premises, is taken or condemned for any public or quasi-public use under Law, by eminent domain or private purchase in lieu thereof (a Taking). For the purposes of
this Section, a material part of the Building shall be over 30% of the Building. Landlord shall also have the right to terminate this Lease if there is a Taking of any portion of the Building or the Complex which would have a material
adverse effect on Landlords ability to profitably operate the remainder of the Building. The terminating party shall provide written notice of termination to the other party within 45 days after it first receives notice of the Taking. The
termination shall be effective on the date the physical taking occurs. If this Lease is not terminated, Base Rent and Tenants Pro Rata Share shall be appropriately adjusted to account for any reduction in the square footage of the Building or
Premises. All compensation awarded for a Taking shall be the property of Landlord. The right to receive compensation or proceeds are expressly waived by Tenant, however, Tenant may file a separate claim for Tenants Property and Tenants
reasonable relocation expenses, provided the filing of the claim does not diminish the amount of Landlords award. If only a part of the Premises is subject to a Taking and this Lease is not terminated, Landlord, with reasonable diligence, will
restore the remaining portion of the Premises as nearly as practicable to the condition immediately prior to the Taking.



|18. | Events of Default.
|--- | ------------------

Each of the following
occurrences shall be a Default: (a) Tenants failure to pay any portion of Rent when due, if the failure continues for 5 days after written notice to Tenant (Monetary Default);
(b) Tenants failure (other than a Monetary Default) to comply with any term, provision, condition or covenant of this Lease, if the failure is not cured within 30 days after written notice to Tenant provided, however, if
Tenants failure to comply cannot reasonably be cured within 30 days, Tenant shall be allowed additional time (not to exceed 60 days) as is reasonably necessary to cure the failure so long as Tenant begins the cure within 10 days after
such notice to Tenant and diligently pursues the cure to completion; (c) Tenant or any guarantor of this Lease becomes insolvent, makes a transfer in fraud of creditors, files a bankruptcy proceeding or has an involuntary proceeding filed
against it which is not dismissed within thirty (30) days of filing, makes an assignment for the benefit of creditors, admits in writing its inability to pay its debts when due or forfeits or loses its right to conduct business; (d) the
leasehold estate is taken by process or operation of Law; (e) Tenant abandons the Premises (vacating the Premises shall not constitute abandonment provided that Tenant otherwise complies with its obligations under this Lease); or
(f) Tenant is in default beyond any notice and cure period under any other lease or agreement with Landlord at the Building or Complex. If Landlord provides Tenant with notice of Tenants failure to comply with any specific provision of
this Lease on 3 separate occasions during any 12 month period, Tenants subsequent violation of such provision shall, at Landlords option, be an incurable Default by Tenant. All notices sent under this Section shall be in satisfaction of,
and not in addition to, notice required by Law.



|19. | Remedies.
|--- | ---------

19.01 Upon Default, Landlord shall have
the right to pursue any one or more of the following remedies:

(a) Terminate this Lease, in which case Tenant shall immediately surrender
the Premises to Landlord. If Tenant fails to surrender the Premises, Landlord, in compliance with Law, may enter upon and take possession of the Premises and remove Tenant, Tenants Property and any party occupying the Premises. Tenant shall
pay Landlord, on demand, all past due Rent and other losses and damages Landlord suffers as a result of Tenants Default, including, without limitation, all Costs of Reletting (defined below) and any deficiency that may arise from reletting or
the failure to relet the Premises. Costs of Reletting shall include all reasonable costs and expenses incurred by Landlord in reletting or attempting to relet the Premises, including, without limitation, legal fees, brokerage
commissions, the cost of alterations and the value of other concessions or allowances granted to a new tenant.



16

Execution Version



(b) Terminate Tenants right to possession of the Premises and, in compliance with Law, remove
Tenant, Tenants Property and any parties occupying the Premises. Landlord may (but, except as expressly provided below, shall not be obligated to) relet all or any part of the Premises, without notice to Tenant, for such period of time and on
such terms and conditions (which may include concessions, free rent and work allowances) as Landlord in its absolute discretion shall determine. Landlord may collect and receive all rents and other income from the reletting. Tenant shall pay
Landlord on demand all past due Rent, all Costs of Reletting and any deficiency arising from the reletting or failure to relet the Premises. The re-entry or taking of possession of the Premises shall not be construed as an election by Landlord to
terminate this Lease. Landlord shall use reasonable efforts to relet the Premises on such terms as Landlord in its sole discretion may determine (including a term different from the Term, rental concessions, and alterations to, and improvement of,
the Premises); however, Landlord shall not be obligated to relet the Premises before leasing other portions of the Building. Landlord shall not be liable for, nor shall Tenants obligations hereunder be diminished because of, Landlords
failure to relet the Premises or to collect rent due for such reletting.

19.02 In lieu of calculating damages under Section 19.01,
Landlord may elect to receive as damages the sum of (a) all Rent accrued through the date of termination of this Lease or Tenants right to possession, and (b) an amount equal to the total Rent that Tenant would have been required to
pay for the remainder of the Term discounted to present value, minus the then present fair rental value of the Premises for the remainder of the Term, similarly discounted, after deducting all anticipated Costs of Reletting. If Tenant is in Default
of any of its non-monetary obligations under the Lease, Landlord shall have the right to perform such obligations. Tenant shall reimburse Landlord for the cost of such performance upon demand together with an administrative charge equal to 10% of
the cost of the work performed by Landlord. The repossession or re-entering of all or any part of the Premises shall not relieve Tenant of its liabilities and obligations under this Lease. Except as set forth in the first sentence of this
Section 19.02, no right or remedy of Landlord shall be exclusive of any other right or remedy. Each right and remedy shall be cumulative and in addition to any other right and remedy now or subsequently available to Landlord at Law or in
equity.



|20. | Limitation of Liability.
|--- | ------------------------

NOTWITHSTANDING ANYTHING
TO THE CONTRARY CONTAINED IN THIS LEASE, THE LIABILITY OF LANDLORD (AND OF ANY SUCCESSOR LANDLORD) SHALL BE LIMITED TO THE INTEREST OF LANDLORD IN THE COMPLEX. TENANT



17



---

Execution Version



SHALL LOOK SOLELY TO LANDLORDS INTEREST IN THE COMPLEX FOR THE RECOVERY OF ANY JUDGMENT OR AWARD AGAINST LANDLORD OR ANY LANDLORD RELATED PARTY.
NEITHER LANDLORD NOR ANY LANDLORD RELATED PARTY SHALL BE PERSONALLY LIABLE FOR ANY JUDGMENT OR DEFICIENCY, AND IN NO EVENT SHALL LANDLORD OR ANY LANDLORD RELATED PARTY BE LIABLE TO TENANT FOR ANY LOST PROFIT, DAMAGE TO OR LOSS OF BUSINESS OR ANY
FORM OF SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGE. BEFORE FILING SUIT FOR AN ALLEGED DEFAULT BY LANDLORD, TENANT SHALL GIVE LANDLORD AND THE MORTGAGEE(S) WHOM TENANT HAS BEEN NOTIFIED HOLD MORTGAGES (DEFINED IN SECTION 23 BELOW), NOTICE AND
REASONABLE TIME TO CURE THE ALLEGED DEFAULT. WITHOUT LIMITING THE FOREGOING, IN NO EVENT SHALL LANDLORD OR ANY MORTGAGEES OR LANDLORD RELATED PARTIES OR TENANT (EXCEPT AS PROVIDED IN SECTION 22 BELOW) EVER BE LIABLE FOR ANY CONSEQUENTIAL OR
INCIDENTAL DAMAGES OR ANY LOST PROFITS. IN NO EVENT SHALL TENANT BE LIABLE TO LANDLORD FOR ANY LOST PROFIT, DAMAGE TO OR LOSS OF BUSINESS OR ANY FORM OF SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGE OTHER THAN AS SET FORTH IN SECTION 22 OF THIS LEASE.

LANDLORD AND TENANT EXPRESSLY DISCLAIM ANY IMPLIED WARRANTY THAT THE PREMISES ARE SUITABLE FOR TENANTS INTENDED COMMERCIAL PURPOSE,
AND TENANTS OBLIGATION TO PAY RENT HEREUNDER IS NOT DEPENDENT UPON THE CONDITION OF THE PREMISES OR THE PERFORMANCE BY LANDLORD OF ITS OBLIGATIONS HEREUNDER, AND, EXCEPT AS OTHERWISE EXPRESSLY PROVIDED HEREIN, TENANT SHALL CONTINUE TO PAY THE RENT,
WITHOUT ABATEMENT, SETOFF OR DEDUCTION, NOTWITHSTANDING ANY BREACH BY LANDLORD OF ITS DUTIES OR OBLIGATIONS HEREUNDER, WHETHER EXPRESS OR IMPLIED.



|21. | Relocation.
|--- | -----------

Intentionally Omitted.



|22. | Holding Over.
|--- | -------------

If Tenant fails to surrender all or
any part of the Premises at the termination of this Lease, occupancy of the Premises after termination shall be that of a tenancy at sufferance. Tenants occupancy shall be subject to all the terms and provisions of this Lease, and Tenant shall
pay an amount (on a per month basis without reduction for partial months during the holdover) for the first 60 days of the holdover equal to 150% of the Base Rent due for the period immediately preceding the holdover, and thereafter equal to 175% of
the Base Rent due for the period immediately preceding the holdover. No holdover by Tenant or payment by Tenant after the termination of this Lease shall be construed to extend the Term or prevent Landlord from immediate recovery of possession of
the Premises by summary proceedings or otherwise. If Landlord is unable to deliver possession of the Premises to a new tenant or to perform improvements for a new tenant as a result of Tenants holdover and Tenant fails to vacate the Premises
within 60 days after the end of the Lease Term, Tenant shall be liable for all damages that Landlord suffers from the holdover.

|23. | Subordination to Mortgages; Estoppel Certificate.
|--- | -------------------------------------------------

Tenant accepts this Lease subject and subordinate to any mortgage(s), deed(s) of trust, ground lease(s) or other lien(s) now or subsequently arising upon the Premises, the Building or the Complex, and to renewals, modifications,
refinancings and extensions thereof (collectively referred to as a Mortgage). The party having the benefit of a Mortgage shall be referred to as a Mortgagee. This clause shall be self-operative, but upon request
from a Mortgagee, Tenant shall execute a commercially reasonable subordination agreement in favor of the Mortgagee. As an alternative, a Mortgagee shall have the right at any time to subordinate its Mortgage to this Lease. Upon request, Tenant,
without charge, shall attorn to any successor to Landlords interest in this Lease. Landlord and Tenant shall each, within 10 days after receipt of a written request from the other, execute and deliver a commercially reasonable estoppel
certificate to those parties as are reasonably requested by the other (including a Mortgagee or prospective purchaser). Without limitation, such estoppel certificate may include a certification as to the status of this Lease, the existence of any
Defaults and the amount of Rent that is due and payable.

Landlord shall deliver its current or future Mortgagees customary form of
Subordination, Non-Disturbance and Attornment Agreement (an SNDA) to the Tenant. Landlord agrees to request that a Mortgagee consider reasonable changes to such Mortgagees standard form of SNDA upon the request of Tenant.
Landlord shall use commercially reasonable efforts to obtain the SNDA from Landlords current Mortgage promptly following the full execution and delivery of this Lease.



|24. | Notice.
|--- | -------

All demands, approvals, consents or
notices (collectively referred to as a notice) shall be in writing and delivered by hand or sent by registered or certified mail with return receipt requested or sent by overnight or same day courier service at the partys
respective Notice Address(es) set forth in Section 1. Each notice shall be deemed to have been received on the earlier to occur of actual delivery or the date on which delivery is refused, or, if Tenant has vacated the Premises or any other
Notice Address of Tenant without providing a new Notice Address, 3 days after notice is deposited in the U.S. mail or with a courier service in the manner described above. Either party may, at any time, change its Notice Address (other than to a
post office box address) by giving the other party written notice of the new address.



|25. | Surrender of Premises.
|--- | ----------------------

At the termination of this
Lease or Tenants right of possession, Tenant shall remove Tenants Property from the Premises, and quit and surrender the Premises to Landlord, broom clean, and in good order, condition and repair, ordinary wear and tear, damage which
Landlord is obligated to repair hereunder casualty for which Tenant is not liable, and condemnation excepted. If Tenant fails to remove any of Tenants Property within 2 days after termination of this Lease or Tenants right to possession,
Landlord, at Tenants sole cost and expense, shall be



19



---

Execution Version



entitled (but not obligated) to remove and store Tenants Property. Landlord shall not be responsible for the value, preservation or safekeeping of
Tenants Property. Tenant shall pay Landlord, upon demand, the expenses and storage charges incurred. If Tenant fails to remove Tenants Property from the Premises or storage, within 30 days after notice, Landlord may deem all or any part
of Tenants Property to be abandoned and title to Tenants Property shall vest in Landlord.



|26. | Miscellaneous.
|--- | --------------

26.01 This Lease shall be
interpreted and enforced in accordance with the Laws of the Commonwealth of Massachusetts and Landlord and Tenant hereby irrevocably consent to the jurisdiction and proper venue of such state or commonwealth. If any term or provision of this Lease
shall to any extent be void or unenforceable, the remainder of this Lease shall not be affected. If there is more than one Tenant or if Tenant is comprised of more than one party or entity, the obligations imposed upon Tenant shall be joint and
several obligations of all the parties and entities, and requests or demands from any one person or entity comprising Tenant shall be deemed to have been made by all such persons or entities. Notices to any one person or entity shall be deemed to
have been given to all persons and entities. Tenant represents and warrants to Landlord that each individual executing this Lease on behalf of Tenant is authorized to do so on behalf of Tenant and that Tenant is not, and the entities or individuals
constituting Tenant or which may own or control Tenant IF Tenant is not a public corporation with stock listed on a nationally recognized stock exchange, or which may be owned or controlled by Tenant are not, among the individuals or entities
identified on any list compiled pursuant to Executive Order 13224 for the purpose of identifying suspected terrorists. Landlord represents and warrants to Tenant that each individual executing this Lease on behalf of Landlord is authorized to do so
on behalf of Landlord and that Landlord is not, and the entities or individuals constituting Landlord or which may own or control Landlord, if Landlord is not a public corporation with stock listed on a nationally recognized stock exchange, or which
may be owned or controlled by Landlord are not, among the individuals or entities identified on any list compiled pursuant to Executive Order 13224 for the purposes of identifying suspected terrorists.

26.02 If either party institutes a suit against the other for violation of or to enforce any covenant, term or condition of this Lease, the prevailing
party shall be entitled to all of its costs and expenses, including, without limitation, reasonable attorneys fees. Landlord and Tenant hereby waive any right to trial by jury in any proceeding based upon a breach of this Lease. Either
partys failure to declare a default immediately upon its occurrence, or delay in taking action for a default, shall not constitute a waiver of the default, nor shall it constitute an estoppel.

26.03 Whenever a period of time is prescribed for the taking of an action by Landlord or Tenant (other than the payment of the Security Deposit or Rent),
the period of time for the performance of such action shall be extended by the number of days that the performance is actually delayed due to strikes, acts of God, shortages of labor or materials, war, terrorist acts, civil disturbances and other
causes beyond the reasonable control of the performing party (Force Majeure).

26.04 Landlord shall have the right to
transfer and assign, in whole or in part, all of its rights and obligations under this Lease and in the Building and Complex. Upon transfer

Execution Version



Landlord shall be released from any further obligations hereunder and Tenant agrees to look solely to the successor in interest of Landlord for the
performance of such obligations, provided that, any successor pursuant to a voluntary, third party transfer (but not as part of an involuntary transfer resulting from a foreclosure or deed in lieu thereof) shall have assumed Landlords
obligations under this Lease.

26.05 Landlord has delivered a copy of this Lease to Tenant for Tenants review only and the delivery
of it does not constitute an offer to Tenant or an option. Tenant represents that it has dealt directly with and only with the Broker as a broker in connection with this Lease. Tenant shall indemnify and hold Landlord and the Landlord Related
Parties harmless from all claims of any other brokers claiming to have represented Tenant in connection with this Lease. Landlord shall indemnify and hold Tenant and the Tenant Related Parties harmless from all claims of any brokers claiming to have
represented Landlord in connection with this Lease.

26.06 Time is of the essence with respect to Tenants exercise of any expansion
or extension rights granted to Tenant. The expiration of the Term, whether by lapse of time, termination or otherwise, shall not relieve either party of any obligations which accrued prior to or which may continue to accrue after the expiration or
termination of this Lease.

26.07 Landlord and any party claiming by, through or under Landlord shall not disturb Tenants use of the
Premises, subject to the terms of this Lease, provided Tenant pays the Rent and fully performs all of its covenants and agreements. This covenant shall be binding upon Landlord and its successors only during its or their respective periods of
ownership of the Building.

26.08 This Lease does not grant any rights to light or air over or about the Building. Landlord excepts and
reserves exclusively to itself any and all rights not specifically granted to Tenant under this Lease. This Lease constitutes the entire agreement between the parties and supersedes all prior agreements and understandings related to the Premises,
including all lease proposals, letters of intent and other documents. Neither party is relying upon any warranty, statement or representation not contained in this Lease. This Lease may be modified only by a written agreement signed by an authorized
representative of Landlord and Tenant.

26.09 Tenant shall not record this Lease or any memorandum or notice without Landlords prior
written consent; provided, however, Landlord agrees to consent to the recordation or registration of a memorandum or notice of this Lease, at Tenants cost and expense (and in a form reasonably satisfactory to Landlord), if the initial term of
this Lease or the initial term plus extension terms granted exceed, in the aggregate, 7 years. If this Lease is terminated before the Term expires, upon Landlords request the parties shall execute, deliver and record an instrument
acknowledging the above and the date of the termination of this Lease, and Tenant appoints Landlord its attorney-in-fact in its name and behalf to execute the instrument if Tenant shall fail to execute and deliver the instrument after
Landlords request therefor within 10 days.

26.10 At any time that Tenant is not a publicly traded company and/or Tenants most
recently audited financial statements are not publicly available on Tenants website, within 15 days after Landlords request (but no more often than once per year unless such request is made



21

Execution Version



in connection with the sale or refinancing of the Building and/or Complex), Tenant will furnish Tenants most recent audited financial statements
(including any notes to them) to Landlord, or, if no such audited statements have been prepared, such other financial statements (and notes to them) as may have been prepared by an independent certified public accountant or, failing those,
Tenants internally prepared financial statements. Notwithstanding the foregoing, Tenant shall have no obligation to provide to Landlord financial statements as provided in the preceding sentence more often than once per year during the Term.
Tenant will discuss its financial statements with Landlord and will give Landlord access to Tenants books and records in order to enable Landlord to verify the financial statements. Landlord will not disclose any aspect of Tenants
financial statements that Tenant designates to Landlord as confidential except (1) to Landlords lenders or prospective purchasers of the Building, (2) in litigation between Landlord and Tenant, and (3) if required by court
order.

26.11 Whenever Tenant requests Landlord to take any action or give any consent required or permitted under this Lease, Tenant will
reimburse Landlord for Landlords reasonable costs incurred in reviewing the proposed action or consent, including, without limitation, reasonable attorneys, engineers or architects fees, within 30 days after Landlords

services companies shall have no right of access to and within the Building, for the installation and operation of telecommunications systems including but not limited to voice, video, data, and any other telecommunications services provided over
wire, fiber optic, microwave, wireless, and any other transmission systems, for part or all of Tenants telecommunications within the Building and from the Building to any other location without Landlords prior written consent. Landlord
shall not unreasonably withhold its consent to the installation and operation of such telecommunications systems, telecommunication services and/or transmission systems if located entirely within the Premises; otherwise, Landlord may withhold or
delay its consent in its sole discretion.

26.13 Tenant acknowledges that the terms and conditions of this Lease are to remain confidential
for Landlords benefit, and, except to the extent required by applicable Law for publicly traded companies, may not be disclosed by Tenant to anyone, by any manner or means, directly or indirectly, without Landlords prior written consent.
The consent by Landlord to any disclosures shall not be deemed to be a waiver on the part of Landlord of any prohibition against any future disclosure.

26.14 The term Hazardous Materials means any substance, material, or waste which is now or hereafter classified or considered to be hazardous, toxic, or dangerous under any Law

the Lease Term shall be a material default of the Lease. Notwithstanding anything herein to the contrary, Tenant shall not permit the Premises or any portion thereof to be used or occupied by any person or entity on the List or by any Embargoed

|--- | -------------------------

28.01 Rooftop
License. Subject to any rights previously given by Landlord to other parties and otherwise subject to such reasonable rules and regulations as Landlord may promulgate from time to time for the purpose of safety and frequency management,
effective as of the Commencement Date, Landlord grants Tenant the appurtenant, non-exclusive, and irrevocable (except upon the expiration or earlier termination of this Lease or pursuant to the terms of this Lease) right at no additional charge, but
otherwise subject to the terms and conditions of this Lease to use the areas on the roof of the Building designated by Landlord at Landlords sole discretion (the Rooftop Installation Areas) : 1) to operate, maintain, repair
and replace communications equipment to be reviewed and reasonably approved by Landlord in advance of any installation (the Equipment) and 2) to install, operate, maintain, repair and replace an antenna serving the Tenants

Execution Version



reasonable designated by Landlord in Landlords sole discretion. Tenants Equipment and the Antenna located in the Rooftop Installation Areas are
defined together as the Rooftop Equipment.

28.02 Installation and Maintenance of Rooftop Equipment. Tenant shall
install the Rooftop Equipment at its sole cost and expense using contractors designated by Landlord (unless Landlord consents in writing to Tenants contractor which consent shall be at Landlords sole discretion) at such times and in such
manner as Landlord may reasonably designate and in accordance with all of the applicable provisions of this Lease regarding Alterations and in compliance with all Laws. Tenant shall not install or operate the Rooftop Equipment until it receives
prior written approval of the Alterations in accordance with Section 9.03. Landlord may withhold approval of the installation or operation of the Rooftop Equipment to the extent such Rooftop Equipment or its installation or operation would
adversely impact the Buildings structure or systems, affect future marketability of the Premises, Building or Complex or would interfere with the use and occupancy of other tenants and occupants of the Building and/or Complex.

Tenant shall, at Tenants sole cost and expense, engage Landlords roofer before beginning any rooftop installations or repairs of the Rooftop Equipment,
whether under this Section 28 or otherwise, and shall always comply with the roof warranty governing the protection of the roof and modifications to the roof. Tenant shall obtain a letter from Landlords roofer following completion of such
work stating that the roof warranty remains in effect. Tenant, at its sole cost and expense, shall inspect areas on the rooftop where the Rooftop Equipment is located at least twice annually and correct any loose bolts, fittings or other
appurtenances and shall repair any damage to the roof caused by the installation or operation of the Rooftop Equipment using a contractor designated by Landlord. Tenant covenants that the installation, existence, maintenance and operation of the
Rooftop Equipment shall not violate any legal requirements or constitute a nuisance under law. Tenant shall pay Landlord on demand (i) all applicable taxes or governmental charges, fees, or impositions imposed on Landlord because of
Tenants ownership and/or use of the Rooftop Equipment under this Section 28, (ii) the amount of any increase in Landlords insurance premiums as a result of the installation and/or use of the Rooftop Equipment. Landlord assumes
no responsibility for interference in the operation of the Rooftop Equipment caused by other tenants equipment, or for interference in the operation of other tenants equipment caused by the Rooftop Equipment, but (i) Landlord shall
reasonably cooperate with Tenant (at no cost to Landlord) to resolve any such interference and shall enforce any rights Landlord may have to prevent such interference and (ii) Tenant shall cooperate with Landlord (at no cost to Landlord) to
resolve any such interference. In the event the Rooftop Equipment shall cause interference with the use and occupancy of other tenants and occupants of the Building and/or Complex (including without limitation such wireless and/or similar rooftop
equipment), Tenant shall (i) immediately cease such use of the Rooftop Equipment causing such interference and promptly remedy such interference and (ii) indemnify and hold Landlord harmless from any Losses which may be imposed upon,
incurred by or asserted against Landlord or any of the Landlord Related Parties by any third party and arising out of or in connection with such interference by Tenant (including violations of Law) or any of Tenants contractors, agents or
employees. In the event such interference may only be remedied by the relocation of the Rooftop Equipment to an alternate location on the Building of the roof, Landlord and Tenant shall reasonably cooperate to identify a suitable location for such
relocation, such alternate

Execution Version



location to be reasonably approved by Landlord. The Rooftop Installation Area is delivered to Tenant in its as-is condition, Landlord makes no
representation or warranty, express or implied, as to the fitness of the roof of the Building for the use of the Rooftop Equipment, and to the extent Tenants desired Rooftop Equipment may not be used due to interference with existing tenants
installations in the Complex, Landlord shall have no liability therefor.

Any cables, conduits or other physical connections between the Rooftop Equipment
and the Premises shall be concealed within permanent walls, floors, columns and ceilings of the Building and in the shafts of the Building provided for such installations, not damaging the appearance of the Building or reducing the usable or
rentable space of the Building. Any installation or maintenance work performed by Tenant, or at Tenants direction, shall be performed without unreasonably interfering with Landlords or any other tenants use of the Complex, and upon
completion of such installation and maintenance (initially and from time to time), Tenant shall restore such portions of the Building to a condition reasonably comparable to that existing prior to such installation or maintenance. Upon termination
or expiration of this Lease, Tenant shall remove any Rooftop Equipment installed by it, at its expense, and shall repair and restore the Building to a condition comparable to that existing prior to such installation.

28.03 Relocation of Rooftop Equipment. Based on Landlords good faith determination that such a relocation is necessary, Landlord reserves
the right to cause Tenant to relocate any Rooftop Equipment to comparably functional space on the roof by giving Tenant prior notice of such intention to relocate. Provided that Landlord has pre-approved the cost thereof, Landlord agrees to pay the
reasonable cost of moving Rooftop Equipment to such other space, taking such other steps necessary to ensure comparable functionality of Rooftop Equipment, and finishing such space to a condition comparable to the then condition of the current
location of Rooftop Equipment. Tenant shall arrange for the relocation of Rooftop Equipment within sixty (60) days after a comparable space is selected by Landlord, using a contractor selected by Landlord (unless Landlord consents in writing to
Tenants contractor which consent shall be at Landlords sole discretion). In the event Tenant fails to arrange for said relocation within the sixty (60) day period, Landlord shall have the right to arrange for the relocation of
Rooftop Equipment at Tenants expense. Any actions by Landlord in connection with a relocation under this Section 28.03 shall be performed in a manner designed to minimize interference with Tenants business.

28.04 No Resale of Services. Under no circumstances shall Tenant sell, lease or license the use of such Rooftop Equipment or services in
connection therewith to other tenants of the Complex.

EXPENSES AND TAXES

This Exhibit is attached to and made a part of the Lease by and between
Normandy Nickerson Road, LLC, a Delaware limited liability company (Landlord) and Bitstream Inc., a Delaware corporation (Tenant) for space in the Building located at 500 Nickerson Road, Marlborough, Massachusetts 01752.

1. Payments.

1.01. Tenant shall pay
Tenants Pro Rata Share of the amount, if any, by which Expenses (defined below) for each calendar year during the Term exceed Expenses for the Base Year (the Expense Excess) and also the amount, if any, by which Taxes
(defined below) for each Fiscal Year during the Term exceed Taxes for the Base Year (the Tax Excess). If Expenses or Taxes in any calendar year or Fiscal Year decrease below the amount of Expenses or Taxes for the Base Year,
Tenants Pro Rata Share of Expenses or Taxes, as the case may be, for that calendar year or Fiscal Year shall be $0. Landlord shall provide Tenant with a good faith estimate of the Expense Excess and of the Tax Excess for each calendar year or
Fiscal Year during the Term. On or before the first day of each month, Tenant shall pay to Landlord a monthly installment equal to one-twelfth of Tenants Pro Rata Share of Landlords estimate of both the Expense Excess and Tax Excess.
After its receipt of the revised estimate, Tenants monthly payments shall be based upon the revised estimate. If Landlord does not provide Tenant with an estimate of the Expense Excess or the Tax Excess by January 1 of a calendar year,
Tenant shall continue to pay monthly installments based on the previous years estimate(s) until Landlord provides Tenant with the new estimate.

1.02. As soon as is practical following the end of each calendar year or Fiscal Year, as the case may be, Landlord shall furnish Tenant with a statement of the actual Expenses and Expense Excess and the actual Taxes
and Tax Excess for the prior calendar year or Fiscal Year, as the case may be, together with reasonable supporting documentation. If the estimated Expense Excess or estimated Tax Excess for the prior calendar year or Fiscal Year, as the case may be,
is more than the actual Expense Excess or actual Tax Excess for the prior calendar year or Fiscal Year, as the case may be, Landlord shall either provide Tenant with a refund or apply any overpayment by Tenant against Additional Rent due or next
becoming due, provided if the Term expires before the determination of the overpayment, Landlord shall refund any overpayment to Tenant after first deducting the amount of Rent due. If the estimated Expense Excess or estimated Tax Excess for the
prior calendar year or Fiscal Year, as the case may be, is less than the actual Expense Excess or actual Tax Excess, for such prior calendar year or Fiscal year, as the case may be, for such prior year, Tenant shall pay Landlord, within 30 days
after its receipt of the statement of Expenses or Taxes, any underpayment for the prior calendar year.

2. Expenses.

2.01. Expenses means all reasonable costs and expenses incurred in each calendar year in connection with operating, maintaining,
repairing, and managing the Building and Complex. Expenses include, without limitation: (a) all labor and labor related costs; (b)



B-1



---

Execution Version



management fees; (c) the cost of equipping, staffing and operating an on-site and/or off-site management office for the Building, provided if the
management office services one or more other buildings or properties, the shared costs and expenses of equipping, staffing and operating such management office(s) shall be equitably prorated and apportioned between the Building and the other
buildings or properties; (d) accounting costs; (e) the cost of services; (f) rental and purchase cost of parts, supplies, tools and equipment; (g) insurance premiums and deductibles; (h) electricity, gas and other utility
costs; and (i) the amortized cost of capital improvements (as distinguished from replacement parts or components installed in the ordinary course of business) made subsequent to the Base Year which are: (1) performed primarily to reduce
current or future operating expense costs, upgrade security or otherwise improve the operating efficiency of the Building and/or Complex; or (2) required to comply with any Laws that are enacted, or first interpreted to apply to the Building
and/or Complex, after the date of this Lease. The cost of capital improvements shall be amortized by Landlord over the lesser of the Payback Period (defined below) or the useful life of the capital improvement as reasonably determined by Landlord.
Payback Period means the reasonably estimated period of time that it takes for the cost savings resulting from a capital improvement to equal the total cost of the capital improvement. Landlord, by itself or through an affiliate,
shall have the right to directly perform, provide and be compensated for any services under this Lease. Any Expenses generally applicable to the Complex as a whole or any portion thereof shall be equitably prorated and Tenants initial Pro-Rata
Share of such Expenses shall be as set forth in Section 1.4 of the Lease. If Landlord incurs Expenses for the Building and/or Complex together with one or more other buildings or properties, whether pursuant to a reciprocal easement agreement,
common area agreement or otherwise, the shared costs and expenses shall be equitably prorated and apportioned between the Building, Complex and the other buildings or properties.

2.02. Expenses shall not include: the cost of capital improvements (except as set forth above); depreciation; principal payments of mortgage and other
non-operating debts of Landlord; the cost of repairs or other work to the extent Landlord is reimbursed by insurance or condemnation proceeds; costs in connection with leasing space in the Building and/or Complex, including brokerage commissions;
lease concessions, rental abatements and construction allowances granted to specific tenants; costs incurred in connection with the sale, financing or refinancing of the Building and/or Complex; fines, interest and penalties incurred due to the late
payment of Taxes or Expenses; organizational expenses associated with the creation and operation of the entity which constitutes Landlord; or any penalties or damages that Landlord pays to Tenant under this Lease or to other tenants in the Building
and/or Complex under their respective leases. Expenses shall further not include: (a) repairs, alterations, additions, improvements or replacements made to rectify or correct any defect in the design, materials or workmanship of the Building or
Common Areas or to comply with any requirements of any governmental authority in effect as of the date of this Lease; (b) rentals and other related expenses incurred in leasing systems, or other equipment ordinarily considered to be of a
capital nature, except equipment or similar services and equipment that is used on a temporary basis to restore Building services to the extent part of capital improvements in Section 2.01; (c) costs of repairs, restoration, replacements
or other work occasioned by (i) fire, windstorm or other casualty and either (aa) payable (whether paid or not) by insurance required to be carried by Landlord under this Lease, or (bb) otherwise paid by insurance then in effect obtained by
Landlord, (ii) the exercise by governmental authorities of the right of eminent domain, whether such taking be total or partial, to the extent that Landlord is compensated by such governmental



B-2

Execution Version



authority for such repairs, restoration, replacements or other work or (iii) the act of any other tenant in the Building, or any other tenants
agents, employees, licensees or invitees to the extent the applicable cost is, in the Landlords reasonable judgment, practically recoverable from such person; (d) wages, salaries benefits, perquisites and compensation paid or given to
(i) executives, shareholders, officers, directors or partners of Landlord or (ii) any principal or partner of the entity from time to time comprising Landlord; (e) costs in connection with the removal and abatement of asbestos or cost
of replacing or retrofitting the HVAC system to comply with laws that regulate or prohibit the use or release of chlorofluorocarbons (CFCs) or hydrocarbons (HCFCs) enacted prior to the date hereof; (f) Landlords general overhead and
administrative expenses not related to the Property; (g) non-cash items, such as deductions for depreciation and amortization of the Building and the Building equipment, or interest on capital invested; (h) legal fees, accountants
fees and other expenses incurred in connection with disputes with Tenant or other tenants or occupants of the Building or associated with the enforcement of any lease or defense of Landlords title to or interest in the Building or any part
thereof; (i) costs (including permit, license and inspection fees) incurred in renovating or otherwise improving, decorating, painting or altering space for other tenants or other occupants or vacant space in the Building; and
(j) interest, penalties or other costs arising out of Landlords failure to make timely payments of its obligations.

2.03. If at
any time during a calendar year the Building and/or Complex is not at least 95% occupied or Landlord is not supplying services to at least 95% of the total Rentable Square Footage of the Building and/or Complex, Expenses shall, at Landlords
option, be determined as if the Building and/or Complex, as applicable, had been 95% occupied and Landlord had been supplying services to 95% of the Rentable Square Footage of the Building and/or Complex. If Expenses for a calendar year are
determined as provided in the prior sentence, Expenses for the Base Year shall also be determined in such manner. Notwithstanding the foregoing, Landlord may calculate the extrapolation of Expenses under this Section based on 100% occupancy and
service so long as such percentage is used consistently for each year of the Term. The extrapolation of Expenses under this Section shall be performed in accordance with the methodology specified by the Building Owners and Managers Association.

3. Taxes shall mean: (a) all real property taxes and other assessments on the Building and/or Complex, including, but not limited
to, gross receipts taxes, assessments for special improvement districts and building improvement districts, governmental charges, fees and assessments for police, fire, traffic mitigation or other governmental service of purported benefit to the
Complex, taxes and assessments levied in substitution or supplementation in whole or in part of any such taxes and assessments and the Complexs share of any real estate taxes and assessments under any reciprocal easement agreement, common area
agreement or similar agreement as to the Complex; (b) all personal property taxes for property that is owned by Landlord and used in connection with the operation, maintenance and repair of the Complex; and (c) all costs and fees incurred
in connection with seeking reductions in any tax liabilities described in (a) and (b), including, without limitation, any costs incurred by Landlord for compliance, review and appeal of tax liabilities. Without limitation, Taxes shall not
include any income, capital levy, transfer, capital stock, gift, estate or inheritance tax. Taxes shall further not include: (i) any income, profits or revenue tax, assessment or charge imposed upon the Rent payable by Tenant under this Lease;
or (ii) penalties due to Landlords lateness or failure to pay taxes, assessments or charges when due (unless such lateness is due to Tenant being late in any



B-3

Execution Version



payment due under this Lease), (iii) any environmental assessments, charges or liens arising in connection with the remediation of Hazardous Materials
from the Leased Premises or Building, the causation of which arose prior to the Commencement Date of this Lease, or to the extent caused by Landlord, its agents, employees or contractors or any tenant of the Building (other than Tenant or its
sublessees or assignees); (iv) except to the extent the same is included as a capital improvement hereunder, costs or fees, including, but not limited to special assessments, payable to public authorities in connection with any construction,
renovation and/or improvements to the Leased Premises or Building other than the Landlords Work, Tenants Work or improvements to the Leased Premises made by or for Tenant, including fees for transit, housing, schools, open space, child
care, arts programs, traffic mitigation measures, environmental impact reports, traffic studies, and transportation system management plans and (v) reserves for future Taxes. If a change in Taxes is obtained for any year of the Term during
which Tenant paid Tenants Pro Rata Share of any Tax Excess, then Taxes for that year will be retroactively adjusted and Landlord shall provide Tenant with a credit, if any, based on the adjustment. Likewise, if a change is obtained for Taxes
for the Base Year, Taxes for the Base Year shall be restated and the Tax Excess for all subsequent years shall be recomputed. Tenant shall pay Landlord the amount of Tenants Pro Rata Share of any such increase in the Tax Excess within 30 days
after Tenants receipt of a statement from Landlord.

4. Audit Rights. Tenant, within 120 days after receiving Landlords statement of
Expenses, may give Landlord written notice (Review Notice) that Tenant intends to review Landlords records of the Expenses for the calendar year to which the statement applies. Within a reasonable time after receipt of the
Review Notice, Landlord shall make all pertinent records available for inspection that are reasonably necessary for Tenant to conduct its review. If any records are maintained at a location other than the management office for the Building, Tenant
may either inspect the records at such other location or pay for the reasonable cost of copying and shipping the records. If Tenant retains an agent to review Landlords records, the agent must be with a CPA firm (or other nationally recognized
lease auditing firm) licensed to do business in the state or commonwealth where the Property is located. Tenant shall be solely responsible for all costs, expenses and fees incurred for the audit, but in no event shall the firm performing such audit
be compensated on a percentage basis. Within 90 days after the records are made available to Tenant, Tenant shall have the right to give Landlord written notice (an Objection Notice) stating in reasonable detail any objection to
Landlords statement of Expenses for that year. If Tenant fails to give Landlord an Objection Notice within the 90 day period or fails to provide Landlord with a Review Notice within the 90 day period described above, Tenant shall be deemed to
have approved Landlords statement of Expenses and shall be barred from raising any claims regarding the Expenses for that year. The records obtained by Tenant shall be treated as confidential. In no event shall Tenant be permitted to examine
Landlords records or to dispute any statement of Expenses unless Tenant has paid and continues to pay all Rent when due. If Tenant shall timely dispute Expenses and/or Taxes, and if such dispute is not resolved between Landlord and Tenant
within thirty (30) days after notice of such dispute from Tenant, then Tenant may refer such disputed item or items to the Boston office of the American Arbitration Association, and the determination of such arbitration, using Real Estate
Industry Arbitration Rules shall be final, conclusive and binding upon Landlord and Tenant. Tenant agrees to pay all costs involved in such arbitration, unless it is determined that Landlords original calculation of the amount of Adjustment
Rent was overstated by more than five percent (5%), in which event Landlord shall pay all costs of such arbitration and shall refund to Tenant the amount of such overstatement.

EXHIBIT C

WORK LETTER

This Exhibit is attached to and made a part of the Lease by and between Normandy
Nickerson Road, LLC, a Delaware limited liability company (Landlord) and Bitstream Inc., a Delaware corporation (Tenant) for space in the Building located at 500 Nickerson Road, Marlborough, Massachusetts 01752.

1. General.

1.1 Purpose.
This Work Letter sets forth the terms and conditions governing Landlords construction of Landlords Work.

1.2 Construction
Representatives. Prior to submission of the Construction Drawings and Specifications pursuant to Section 2 hereof, each of Landlord and Tenant shall designate a representative (Representative) who shall act for Landlord
and Tenant, as the case may be, in all matters regarding Landlords Work. Tenant hereby designates John Waitkunas at Diversified Project Management as its Representative and Landlord hereby designates Andy Spaulding as its Representative.

All inquiries, requests, instructions, authorizations or other communications with respect to the Landlords Work shall be made in
writing to Landlords Representative or Tenants Representative, as the case may be. Authorizations made by Tenants Representative shall be binding and Tenant shall be responsible for all costs authorized by Tenants
Representative. Either party may change its Representative at any time by written notice to the other party. Landlord shall not be obligated to respond to or act upon any plan, drawing, change order approval or other matter relating to the
Landlords Work until it has been executed by Tenants Representative.

2. Design and Schedule.

2.1 Plans for Landlords Work. The Construction Drawings and Specifications as used herein shall mean the construction
working drawings, the mechanical, electrical and other technical specifications, and the finishing details, including wall finishes and colors and technical and mechanical equipment installation, if any, all of which details the installation of the
Landlords Work in the Premises. Tenant shall cooperate with Landlord in the finalization of the Construction Drawings and Specifications and shall notify Landlord of Tenants selection of the color of paint, carpet or other materials
within five (5) business days of Landlords request for such selection. Reference to the Construction Drawings and Specifications with respect to the entire Premises is attached hereto as Exhibit C-1.

2.2 Approvals by Landlord. All Construction Drawings and Specifications for the Landlords Work (collectively, the Final
Plans) shall be delivered to the Tenant for its final approval, which shall not be unreasonably withheld or delayed, provided that such Final Plans are consistent with the contemplated layout of the Premises as shown on the Construction
Drawings and Specifications referenced in Exhibit C-1. Tenant shall notify Landlord in writing, within three (3) days of Tenants receipt of the Final Plans (or revision thereof), of its approval



C-1



---

Execution Version



or a detailed reason of its disapproval (each, an Approval Period). In the event Tenant disapproves of the Final Plans and requests
changes thereto for any reason other than the failure of the Final Plans to be consistent with the Construction Drawings and Specifications referenced in Exhibit C-1, then, after the initial Approval Period, each subsequent Approval Period shall be
a Tenant Delay (defined below).

3. Construction of Landlords Work. The Landlords Work shall be performed by The Walsh
Company (the General Contractor). Landlord shall enter into a contract (the Construction Contract) with the General Contractor for performance of the Landlords Work. Landlord shall obtain all permits necessary
for construction of the Landlords Work. Landlord then shall promptly cause the General Contractor to commence, construct and complete the Tenant Improvements in a good and workmanlike manner and in accordance with the Final Plans, at
Landlords sole cost and expense (except as otherwise provided herein). In the event that the Landlords Work is not performed in a good and workmanlike manner or in conformity with the Final Plans, the Landlord shall require the General
Contractor to comply therewith. Landlords Work shall strictly comply with all governmental rules, regulations, laws and building codes; and all private covenants, conditions and restrictions applicable thereto. Tenants approval of the
Final Plans shall not release Landlord from any of its obligations hereunder.

The Landlords Work shall be deemed to be
Substantially Complete on the date that all Landlords Work have substantially been performed, other than any details of construction, mechanical adjustment or any other similar matter, the non-completion of which does not
interfere with Tenants use of the Premises, which matters can reasonably be completed within thirty (30) days, and all necessary governmental permits and approvals necessary for use and occupancy of the Premises have been issued. If
Landlord is delayed in the performance of the Landlords Work as a result of (i) the negligence or willful misconduct of Tenant or Tenants agents, employees, contractors or vendors, including, without limitation, changes requested by
Tenant after the Final Plans have been approved by Landlord and Tenant, (ii) Tenants failure to comply with any of its obligations under the Lease, (iii) Tenants failure to approve or comment upon the Construction Drawings and
Specifications within the timeframe set forth herein or meet any of the other timeframes set forth in this Exhibit C (including without limitation the specification of the color of paint, carpet or other materials within five (5) business days
of Landlords request for such selection), (iv) Tenants failure to reimburse Landlord for any amounts due under this Exhibit C, (v) the specification of any non-standard materials or equipment with long lead times where Tenant
is notified by Landlord at the time of specification of such materials or equipment of the delay associated with said non-standard materials or equipment and fails to provide a reasonable substitute or withdraw the request for such material or
equipment within three (3) business days of such notification or (vi) any Approval Periods beyond the initial Approval Period other than those necessary due to the failure of the Final Plans to be consistent with the Construction Drawings
and Specifications referenced in Exhibit C-1 (each, a Tenant Delay), the Landlords Work shall be deemed to be Substantially Complete on the date that Landlord could reasonably have been expected to Substantially Complete the
Landlords Work absent any Tenant Delay.

Within ten (10) days following notice from Landlord to Tenant that Landlord believes
Landlords Work is Substantially Complete, Landlord and Tenant shall walk-through the



C-2



---

Execution Version



Premises and jointly complete a punchlist of items of the Landlords Work needing completion or correction by the General Contractor. Landlord shall use
commercially reasonable efforts to complete or correct all punch-list items within thirty (30) days after the walk-through inspection and shall notify Tenant in writing of the completion thereof. Within ten (10) days after Landlords
notification to Tenant of completion or correction of all the punchlist items, Landlord and Tenant again shall walk-through the Premises to determine if all the punchlist items have been completed or corrected, and shall prepare and
resubmit to the Contractor a revised punchlist of any remaining incomplete or uncorrected items which shall be completed as soon as reasonably practicable.

4. Change Orders. If Tenant requests any change or addition to or subtraction from the Landlords Work (Change Order) after Tenants approval of the final and complete Construction
Drawings and Specifications for the Landlords Work, Landlord shall respond to Tenants request for consent as soon as reasonably possible and include a good faith estimate of the actual cost of, and additional time, if any, required to
perform the work contemplated by such Change Order request. Tenant may, within five (5) business days of its receipt of such estimate, elect to rescind its request for such Change Order upon written notice to Landlord. All costs associated with
any Change Order shall be the responsibility of Tenant, and to the extent such Change Order shall cause an increase in the Costs of Landlords Work (defined below), the costs associated with such Change Order in excess of the Costs of
Landlords Work shall be paid to Landlord as additional rent and as a condition of the approval of such Change Order within five (5) business days of Landlords approval therefor. Any such changes, additions or modifications that
Tenant desires to make to the Final Plans after final approval shall not be unreasonably withheld, except that Landlord shall have complete discretion with regard to granting or withholding approval for the Building structure, system or appearance
as provided in Section 2.2 above or would cause a delay in construction of the Landlords Work. As used herein, Costs of Landlords Work shall mean the design and architectural costs to prepare the Construction Drawings
and Specifications for the Landlords Work, costs of all labor and materials incurred to complete Landlords Work, and costs for removal of all construction debris, general contractors fees and any permit or license fees necessary
for completion of construction of Landlords Work.

5. Tenant Improvement Allowance. In addition to the turn-key preparation of
the Landlord Work, an amount not to exceed $410,670.00 may be applied by Tenant for various expenses as provided in Section 1.07 of the Lease. As applicable, Tenant acknowledges that any request for payment of the Improvement Allowance must be
delivered to Landlord together with executed lien waivers, contractors statements and/or invoices and owners statements covering the work for which reimbursement is then being requested and any other documents reasonably requested by
Landlord as evidence that the work and/or equipment has been completed and paid for, and Landlord shall thereafter disburse such portion of the remaining Improvement Allowance within thirty (30) days after the Landlords receipt of all
required documentation. Notwithstanding any provision to the contrary set forth in this Lease, Tenant shall not be entitled to any remaining portion of the un-disbursed Improvement Allowance to the extent Tenant does not request the same prior to
the expiration of the eighteenth (18th) Lease Month.

Landlords or any other tenants or occupants business or with the rights and privileges of any person lawfully in the Building or Complex (Labor Disruption). Tenant shall take the actions necessary to resolve the
Labor Disruption, and shall have pickets removed and, at the request of Landlord, immediately terminate any work in the Premises that gave rise to the Labor Disruption, until Landlord gives its written consent for the work to resume. Tenant shall
have no claim for damages against Landlord or any of the Landlord Related Parties nor shall the Commencement Date of the Term be extended as a result of the above actions.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|22. | Deliveries to and from the Premises shall be made only at the times in the areas and through the entrances and exits reasonably designated by Landlord. Tenant shall not make
deliveries to or from the Premises in a manner that might interfere with the use by any other tenant of its premises or of the Common Areas, any pedestrian use, or any use which is inconsistent with good business practice.

EXHIBIT F

ADDITIONAL PROVISIONS

This Exhibit is attached to and made a part of the Lease by and
between Normandy Nickerson Road, LLC, a Delaware limited liability company (Landlord) and Bitstream Inc., a Delaware corporation (Tenant) for space in the Building located at 500 Nickerson Road, Marlborough, Massachusetts
01752.



|A. | Parking
|-- | -------

Landlord shall provide non-reserved
vehicle access to the surface parking lot located adjacent to the Building at a ratio of 3.5 vehicle spaces per each one thousand (1,000) rentable square feet of the Premises at no additional expense to Tenant (i.e. non-reserved parking for
ninety-six (96) motor vehicles based upon the Tenants occupancy of 27,378 rentable square feet; the foregoing referred to herein as Tenants Parking). Tenants Parking shall be non-transferable (directly or
indirectly) to any other institutions, entities or individuals other than as appurtenant to a Transfer or Permitted Transfer. Except for reasonable business travel of Tenants employees, overnight parking at the Building shall be strictly
prohibited.

Landlord shall not be responsible for money, jewelry, automobiles or other personal property lost in or stolen from the
parking lot. Landlord shall not be liable for any loss, injury or damage to persons using the parking lot or automobiles or other property thereon, it being agreed that, to the fullest extent permitted by law, the use of the parking lot and the
parking spaces shall be at the sole risk of Tenant and its employees. Except for emergency repairs, Tenant and its employees shall not perform any work on any automobiles while located in the parking lot.

Tenants Parking shall be subject to such reasonable rules and regulations therefor as may be set and changed with reasonable prior notice by the
Landlord from time to time and uniformly enforced by Landlord during the Term provided that such rules shall not at any time incorporate a charge or fee for parking. Landlord agrees that such rules and regulations shall be established and applied by
Landlord in a non-discriminatory fashion, such that all rules and regulations shall be generally applicable to all other tenants of the Building of a similar nature of Tenant. Tenants Parking is non-assignable (except as part of a sublease or
assignment of this Lease permitted by the terms of this Lease) and intended solely for the use of Tenants employees working from and business invitees to the Premises; and as such Tenant shall not offer them for use or
license to any other entity, the general public, or any other tenants of the Building other than a valid sublessee of all or a portion of the Premises or assignee of the Lease. All such appurtenant rights for parking as set forth in this
Section are automatically terminated upon termination of this Lease, and shall have no separate independent validity or legal standing. Landlord reserves the right to relocate and/or temporarily close any or all of the parking facilities to the
extent necessary in the event of a casualty or governmental taking or for maintenance and repairs of the parking facility provided Landlord shall reopen the same or provide replacement parking facilities as soon as practicable thereafter provided
that any relocation shall be reasonably proximate to the Building.

Execution Version



|B. | Extension Option
|-- | ----------------

Provided the original
Tenant named herein (or an Affiliate pursuant to a Permitted Transfer) is itself occupying not less than sixty percent (60%) of the entire Premises at the time of giving its notice to exercise its option and at the commencement of the Extension
Term (as defined herein), Tenant shall have the right and option to extend the Term for two (2) additional periods of five (5) years (each an Extension Term). The right and option to so extend the term shall be personal
to the Tenant executing this Lease (or an Affiliate pursuant to a Permitted Transfer) and such right and option may not be assigned or transferred to any other party or entity. The first Extension Term is to commence immediately upon expiration of
the initial Term (the Original Term) and the second Extension Term is to commence immediately upon expiration of the first Extension Term, provided that both instances Tenant shall give Landlord notice of Tenants exercise of
such option by no later than nine (9) months prior to the then scheduled expiration of the Original Term (or first Extension Term, as applicable) (except as otherwise provided in Section D below with respect to a simultaneous exercise of a
Right of First Refusal), and provided further that no Default, or event which with the giving of notice or the passage of time, or both, would constitute a Default, unless the same is cured within the applicable cure period which exists at the time
of giving such notice or at the commencement of either Extension Term. If a Default, or event which with the giving of notice or the passage of time, or both, would constitute a Default, exists at the time of giving such notice or at the time of
commencement of an Extension Term, Tenants exercise of such option shall, at the option of Landlord, be null and void and of no further force and effect. Prior to the exercise by Tenant of any such option, the expression Term shall
mean the Original Term. Except as expressly otherwise provided in the following paragraph, all the terms, covenants, conditions, provisions and agreements in the Lease contained herein shall be applicable to the Extension Term, except that following
the second Extension Term there shall be no further extension terms. If Tenant shall give notice of its exercise of said option to extend in the manner and within the time period provided aforesaid, the Term (or first Extension Term, as applicable)
shall be extended upon the giving of such notice without the requirement of any further action on the part of either Landlord or Tenant. If Tenant shall fail to give timely notice of the exercise of such option as aforesaid, Tenant shall have no
right to extend the Term of this Lease, time being of the essence of the foregoing provisions.

The Annual Base Rent payable during each
Extension Term shall be an amount equal to 100% of the Fair Market Rent for the Premises as of the commencement date of the applicable Extension Term. The Fair Market Rent shall be determined in accordance with the provisions set forth below. If for
any reason the Annual Base Rent payable during an Extension Term has not been determined as of the commencement date of the Extension Term, Tenant shall pay the Annual Base Rent payable for the year immediately preceding the commencement of such
Extension Term until the Annual Base Rent for the Extension Term is determined, at which time, an appropriate adjustment, if any, shall be made.

Fair Market Rent shall mean the anticipated rent for the Premises as of the commencement of the Extension Term under market conditions then existing in as-is condition. No later than one (1) month after
Tenants Extension Notice, Landlord shall notify Tenant of Landlords estimate of the Fair Market Rent in writing. No later than fifteen (15) days after such written notification, Tenant may dispute Landlords estimate of Fair
Market Rent upon written notice thereof to Landlord which written notice shall contain Tenants estimate of the Fair Market Rent. If Tenant disputes Landlords estimate of Fair Market Rent within such



-2



---

Execution Version



fifteen (15) day period, then the Fair Market Rent shall be determined by agreement between Landlord and Tenant during the next thirty (30) day
period following Tenants notice of dispute (the Discussion Period), but if Landlord and Tenant are unable to agree upon the Fair Market Rent during the Discussion Period, then the Fair Market Rent shall be determined by a
board of three (3) M.A.I. appraisers as hereafter provided, each of whom shall have at least five (5) years experience in the Boston Metro-west office rental market and each of whom is hereinafter referred to as appraiser,
Tenant and Landlord shall each appoint one such appraiser and the two appraisers so appointed shall appoint the third appraiser (the Neutral Appraiser). The cost and expenses of each appraiser appointed separately by Tenant and
Landlord shall be borne by the party who appointed the appraiser. The cost and expenses of the third appraiser shall be shared equally by Tenant and Landlord. Landlord and Tenant shall appoint their respective appraisers no later than fifteen
(15) days after the expiration of the Discussion Period and shall designate the appraisers so appointed by notice to the other party. The two appraisers so appointed and designated shall appoint the Neutral Appraiser no later than twenty
(20) days after the end of the Discussion Period and shall designate such appraiser by notice to Landlord and Tenant. Each of Landlords appointed appraiser and Tenants appointed appraiser shall issue their respective estimates of
Fair Market Rent within thirty (30) days after the end of the Discussion Period. The Neutral Appraiser shall then choose either the Landlords appointed appraisers estimate of Fair Market Rent or the Tenants appointed
appraisers estimate of Fair Market Rent as the Fair Market Rent of the space in question as of the commencement of the Extension Term and shall notify Landlord and Tenant of its determination no later than sixty (60) days after the end of
the Discussion Period. The Fair Market Rent of the subject space determined in accordance with the provisions of this Section shall be deemed binding and conclusive on Tenant and Landlord. Notwithstanding the foregoing, if either party shall fail to
appoint its appraiser within the period specified above (such party referred to hereinafter as the failing party) the other party may serve notice on the failing party requiring the failing party to appoint its appraiser within ten
(10) days of the giving of such notice and if the failing party shall not respond by appointment of its appraiser within said (10) day period, then the appraiser appointed by the other party shall be the sole appraiser whose choice of
either the Landlords or the Tenants estimate of Fair Market Rent shall be binding and conclusive upon Tenant and Landlord. All times set forth herein are of the essence.



|C. | Tenant Identification
|-- | ---------------------

Landlord shall
provide at Landlords cost, in the Building-standard format, Building-standard signage. Subject to the approval of Landlord as to conformance with the sign criteria for Marlborough Technology Park not to be unreasonably withheld, conditioned or
delayed, and subject to the approval of all applicable governmental authorities, Tenant may, at Tenants cost, install an exterior sign on Tenants proportionate share of the outside of the Building in a location to be determined by
Landlord in Landlords reasonable discretion.



|D. | Right of First Refusal
|-- | ----------------------

Subject to the terms
and conditions set forth below and subject to the existing prior rights of tenants and such tenants rights to extend with respect to such spaces, Tenant shall have an ongoing Right of First Refusal for the 4,346 rentable square
foot space adjacent to the Premises as more particularly shown on Exhibit A (the ROFR Space).



-3



---

Execution Version



Any lease to Tenant of the ROFR Space shall be for a term which shall be coterminous with this Lease,
provided that if the Third Party Offer (defined below) is for a period in excess of the then-remaining Term (or initial Extension Term), then Tenants right to exercise the Right of First Refusal for such ROFR Space shall be contingent upon
Tenant effectively exercising its Extension Option set forth in Section B above upon the terms and conditions set forth in Section B at the same time as it exercises such Right of First Refusal, and the term of the ROFR Space shall be coterminous
with the expiration of the applicable Extension Term (as defined in Section B above). If Landlord receives a bona fide written offer (Third Party Offer) to lease ROFR Space, and if Landlord desires to accept the Third Party Offer,
it shall first make a written offer to Tenant (the ROFR Notice) upon the same terms as the Third Party Offer (except that the term of such ROFR Space shall be as set forth in this Section D) and any improvements contributed by
Landlord shall be pro-rated to account for any variance in the length of term. The ROFR Notice to Tenant shall specify the rent for such ROFR Space, the date of availability of such ROFR Space and all other material terms and conditions which will
apply to such ROFR Space. In the event the Third Party Offer includes space or property in addition to the ROFR Space, the ROFR Notice shall reasonably eliminate such additional space and adjust or prorate financial terms to cover only the ROFR
Space and the ROFR Notice shall disclose such modifications. Tenant will notify Landlord within five (5) Business Days of Tenants receipt of the ROFR Notice if Tenant wishes to lease such ROFR Space from Landlord on the terms and
conditions so specified. If Tenant notifies Landlord that it wishes to lease the ROFR Space, Landlord and Tenant shall execute an amendment to the Lease incorporating the ROFR Space into the Premises upon the terms contained in the ROFR Notice
within fifteen (15) days following the later of the date of giving of Tenants Notice or the date a draft of the amendment is first delivered by Landlord to Tenant. If Tenant fails to notify Landlord within said five (5) Business Day
period that Tenant intends to lease such ROFR Space, or fails to simultaneously exercise an Extension Option if required as aforesaid, or fails to execute the aforesaid amendment within fifteen (15) days following the later of the date of
giving of Tenants Notice or the date a draft of the amendment is first delivered by Landlord to Tenant (or, if later, within five (5) business days following Tenants receipt from Landlord of an execution version of such amendment
incorporating the terms contained in the ROFR Notice) (the ROFR Waiver Date), Tenant shall be deemed to have waived its rights with respect to the ROFR Space for a period of one (1) year from the ROFR Waiver Date and Landlord
shall be entitled to lease all or any portion of such ROFR Space to any third party or parties on such terms and conditions, including, without limitation, options to extend the term of such lease and/or expand the premises under such lease, and for
such rent as Landlord determines all in its sole discretion. Following the expiration of the one-year period following any ROFR Waiver Date, the ROFR Space shall again be subject to Tenants Right of First Refusal in accordance with and subject
to the provisions of this Section D.

Notwithstanding any contrary provision of this Section or any other provision of this Lease, any
Right of First Refusal and any exercise by Tenant of any Right of First Refusal shall be void and of no effect unless on the date Tenant notifies Landlord that it is exercising the Right of First Refusal and on the commencement date of the amendment
for the ROFR Space (i) this Lease is in full force and effect and (ii) no default of Tenant has occurred under the Lease which remains continuing and uncured after any applicable notice and opportunity to cure and (iii) Tenant shall
not have assigned this Lease (other than to an Affiliate), and there shall not be any sublease or subleases in effect as of the commencement of the term of the Lease for any of the



-4



---

Execution Version



ROFR Space as of the date of Landlords notice of the ROFR Space availability and (iv) if such ROFR Notice is delivered prior to any exercise by
Tenant of the Early Termination Option set forth in Section E below, Tenant shall waive such Early Termination Option in writing. Additionally, the Right of First Refusal shall not apply to any Third Party Offer which is for a term which exceeds the
Term of this Lease and any remaining exercisable Extension Options, and Landlord shall have no obligation to provide Tenant with notice of any such Third Party Offer.



|E. | Early Termination Option
|-- | ------------------------

Tenant shall have the one-time option to terminate this Lease effective as of the last day of the eighty-seventh (87th) Lease Month (the Early Termination Date) provided that (i) Tenant gives Landlord not less than nine (9) months prior written notice to terminate (the
Termination Notice), (ii) Tenant provides the Termination Payment (defined below) with the Termination Notice, (iii) Tenant is not in Default hereunder either at the time of the Termination Notice or on the Early
Termination Date and (iv) all Base Rent, Additional Rent and all other charges due under this Lease have been paid on or before the Early Termination Date. Together with the Termination Notice, Tenant shall pay Landlord a Termination
Payment of $400,000.00. As of the Early Termination Date, neither party shall have any rights, liabilities or obligations under this Lease for the period accruing after the Early Termination Date, except those which, by the provisions of this
Lease, expressly survive the termination of the term of this Lease, and Tenant shall surrender the Premises in the condition required under this Lease. This option to terminate shall be self-operative as provided herein and no additional agreement
between Landlord and Tenant shall be necessary to effectuate such termination. This Early Termination Option shall be available to Tenant irrespective of assignment of the Lease (provided such assignment is permitted under the Lease) or one or more
subleases of all or a portion of the Premises; provided, however that if any portion of the Premises is sublet, or if this Lease shall be assigned, then this Early Termination Option may be exercised by Tenant only if all then-existing subleases
specifically provide that they shall automatically terminate simultaneously with the Lease upon Tenants (or Tenants permitted assignees) exercise of the Early Termination Option.



|F. | Restroom Upgrades
|-- | -----------------

Landlord shall, at
Landlords sole cost and expense as soon as reasonably practicable following Substantial Completion of Landlords Work, upgrade the restrooms located in the Premises using Building-standard materials consistent with Landlords
standard upgrades to the restrooms in other leased premises in the Complex. Tenant acknowledges that such restroom upgrades are not part of Landlords Work.
