3. Adjustment of Commencement Date; Possession.



3.01 If Landlord is required to perform Landlord Work prior to the Commencement Date: (a) the date set forth in Section 1.06
as the Commencement Date shall instead be defined as the Target Commencement Date; (b) the actual Commencement Date shall be the date on which the Landlord Work is Substantially Complete (defined below); and (c) the Termination
Date will be the last day of the Term as determined based upon the actual Commencement Date. Landlord shall diligently attempt to Substantially Complete the Landlord Work by the Target Commencement Date but failure to so complete despite such
efforts shall not be a default by Landlord or otherwise render Landlord liable for damages. Promptly after the determination of the Commencement Date, Landlord and Tenant shall enter into a commencement letter agreement in the form attached as
Exhibit D. If the Termination Date does not fall on the last day of a calendar month, Landlord and Tenant may elect to adjust the Termination Date to the last day of the calendar month in which Termination Date occurs by the mutual execution
of a commencement letter agreement setting forth such adjusted date. The Landlord Work shall be deemed to be Substantially Complete the later of (i) the date that all Landlord Work has been performed, other than any details of
construction, mechanical adjustment or any other similar matter, the non-completion of which does not materially interfere with Tenants use of the Premises, and (ii) the date Landlord receives from the appropriate governmental authority all
approvals necessary for the issuance of a certificate of occupancy with respect to the Landlord Work performed by Landlord or its contractors in the Premises (or would have received such approvals absent any Tenant Delay). If Landlord is delayed in
the performance of the Landlord Work as a result of the acts or omissions of Tenant, the Tenant Related Parties (defined in Section 13) or their respective contractors or vendors, including, without limitation, changes requested by Tenant to
approved plans, Tenants failure to comply with any of its obligations under this Lease, or the specification of any non-standard materials or equipment with long lead times (a Tenant Delay), the Landlord Work shall be deemed
to be Substantially Complete on the date that Landlord could reasonably have been expected to Substantially Complete the Landlord Work absent any Tenant Delay.



3.02 Subject to Landlords obligation, if any, to perform Landlord Work, the Premises are accepted by Tenant in as is condition and
configuration without any representations or warranties by Landlord. By taking possession of the Premises, Tenant agrees that the Premises are in good order and satisfactory condition. 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, however Landlord shall use reasonable efforts to obtain possession of the space. The commencement date for the space, in such event, shall
be postponed until the date Landlord delivers possession of the Premises to Tenant free from occupancy by any party. If Tenant takes possession of the Premises before the Commencement Date, such possession shall be subject to the terms and
conditions of this Lease and Tenant shall pay Rent (defined in Section 4.01) to Landlord for each day of possession before the Commencement Date. Tenant, however, shall not be required to pay Rent for any days of possession before the Commencement
Date during which Tenant, with the approval of Landlord, is in possession of the Premises for the sole purpose of performing improvements or installing furniture, equipment or other personal property. Notwithstanding the foregoing, if there has been
no Tenant Delay and the Commencement Date does not



4



---

occur by October 1, 2003 (the Outside Completion Date), Tenant, as its sole remedy, shall provide Landlord with written notice that if the
Commencement Date does not occur by November 1, 2003 Tenant shall terminate this Lease. In such event, if the Commencement Date does not occur by November 1, 2003, this Lease shall be deemed null and void and of no further force and effect and
Landlord shall promptly refund any Security Deposit previously advanced by Tenant under this Lease and, so long as Tenant has not previously been declared in Default under any of its obligations under the Work Letter, the parties hereto shall have
no further responsibilities or obligations to each other with respect to this Lease. Landlord and Tenant acknowledge and agree that: (i) the determination of the Commencement Date shall take into consideration the effect of any Tenant Delay; and
(ii) the Outside Completion Date shall be postponed by the number of days the Commencement Date is delayed due to events of Force Majeure. Notwithstanding anything herein to the contrary, if Landlord reasonably determines despite diligent efforts
that it will be unable to cause the Commencement Date to occur by the Outside Completion Date, Landlord shall have the right to immediately cease its performance of the Landlord Work and provide Tenant with written notice (the Outside
Extension Notice) of such inability, which Outside Extension Notice shall set forth the date on which Landlord reasonably believes that the Commencement Date will occur. Upon receipt of the Outside Extension Notice, Tenant shall have the right
to terminate this Lease by providing written notice of termination to Landlord within 5 Business Days after the date of the Outside Extension Notice. In the event that Tenant does not terminate this Lease within such 5 Business Day period, the
Outside Completion Date shall automatically be amended to be the date set forth in Landlords Outside Extension Notice.



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.
Tenant shall pay Landlord an administration fee equal to 5% of all past due Rent, provided that Tenant shall be entitled to a grace period of 5 days for the first 2 late payments of Rent in a calendar year. In addition, past due Rent shall accrue
interest at the Prime Rate (defined herein) plus 4% per annum. For purposes hereof, the Prime Rate shall be the per annum interest rate publicly announced as its prime or base rate by a federally insured bank selected by Landlord in the
state in which the Building is located. Forbearance by Landlord to enforce one or more remedies shall not constitute a waiver of any Default. 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.
| | ---- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Premises shall be used for the Permitted Use and for no other use whatsoever. Tenant shall comply with all statutes,
codes, ordinances, orders, rules and regulations of any municipal or governmental entity whether in effect now or later, including the Americans with Disabilities Act (Law(s)), regarding the operation of Tenants business and
the use, condition, configuration and occupancy of the Premises. 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 use of the Premises, other than for general office use, or Alterations or improvements in the Premises performed or requested by Tenant. As of the date hereof, Landlord has not received notice from any
governmental agencies that the Building is in violation of Title III of the Americans with Disabilities Act.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. Nothing herein shall require Tenant to perform any alterations, additions or
improvements which are necessary to comply with Laws with respect to the Common Areas, unless such compliance relates to the Common Areas on any floor on which the Premises are located and arises directly out of the performance of work by or on
behalf of Tenant in the Premises or Tenants use of the Premises for purposes other than general office use. In addition, nothing herein shall require Tenant, with respect to the Common Areas or the Premises, to comply with Laws which require
structural alterations, capital improvements or the installation of new or additional mechanical, electrical, plumbing or fire/life safety systems on a Building-wide basis without reference to the particular use of Tenant. Landlord will, at
Landlords expense (except to the extent properly included in Expenses), perform all acts required to comply with such Laws with respect to the foregoing as the same affect the Premises and the Building. In addition, Landlord, at
Landlords expense (except to the extent properly included in Expenses), shall be responsible for complying with Title III of the Americans with Disabilities Act (ADA) with respect to the Common Areas of the Building (including any Common Area
corridors) and the Landlord Work. Notwithstanding the foregoing, Landlord shall have the right to contest any alleged violation of the ADA or other Laws in good faith, including, without limitation, the right to apply for and obtain a waiver or
deferment of compliance, the right to assert any and all defenses allowed by Law and the right to appeal any decisions, judgments or rulings to the fullest extent permitted by Law. Landlord, after the exhaustion of any and all rights to appeal or
contest, will make all repairs, additions, alterations or improvements necessary to comply with the terms of any final order or judgment, provided that if Landlord elects not to contest any alleged violation, Landlord will promptly make necessary
all repairs, additions, alterations or improvements. 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).



6. Security Deposit.



6.01 The Security Deposit shall be delivered to Landlord upon the 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



6



---

Security Deposit to its original amount. Landlord shall return any unapplied portion of the Security Deposit to Tenant within 30 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 shall 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.



6.02 All of 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 amount of $250,000.00; (b) be issued on the form attached hereto as Exhibit H; (c) name Landlord as its beneficiary; and (d) be drawn on an FDIC insured financial institution reasonably satisfactory to the Landlord.
Notwithstanding anything herein to the contrary, provided Tenant is not in Default under this Lease as of the effective date of any reduction of the Security Deposit, Tenant shall have the right to reduce the amount of the Security Deposit to be as
follows: (i) $200,000.00 effective as of the second annual anniversary of the Commencement Date; and (ii) $150,000.00 effective as of the fourth annual anniversary of the Commencement Date. Such reduction shall be accomplished by having Tenant
provide Landlord with a substitute Letter of Credit in the reduced amount. 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
reasonably satisfactory to the Landlord at the time of the issuance thereof.



6.03 If Landlord draws on the Letter of Credit as permitted in this Lease or the Letter of Credit, 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. In the alternative, Tenant may provide Landlord with cash, to be held by
Landlord in accordance with this Article, equal to the restoration amount required under the Letter of Credit.



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. Tenant shall have the right to receive HVAC
service during hours other than Building Service Hours by paying Landlords then standard charge for additional HVAC service and providing such prior notice as is reasonably specified by Landlord; (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 Property.



7



---

7.02 Electricity used by Tenant in the Premises shall be paid for by Tenant by a separate charge off a
separate meter of the Premises payable by Tenant directly to the electric utility. 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 reasonably deems to be standard for the Building. 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. However, if the Premises, or a material portion of the Premises, are made untenantable for a period in excess of 3 consecutive
Business Days as a result of a Service Failure that is reasonably within the control of Landlord to correct, then Tenant, as its sole remedy, shall be entitled to receive an abatement of Rent payable hereunder during the period beginning on the
4thconsecutive Business Day of the Service Failure and ending on the day the service has been restored. If the
entire Premises have not been rendered untenantable by the Service Failure, the amount of abatement shall be equitably prorated.



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 at least 30 days prior to the Termination Date, may require Tenant, at its expense, to remove (a) any Cable (defined in Section 9.01)
installed by or for the benefit of Tenant, and (b) any Landlord Work or Alterations 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 (collectively referred to as Required Removables). Required Removables shall include, without limitation, internal stairways, raised floors, personal baths and showers, vaults,
rolling file systems and structural alterations and modifications. The designated Required Removables shall be removed by Tenant before the Termination Date. Notwithstanding the foregoing, Tenant shall not be required to remove any portion of the
Landlord Work shown on the Plans as of the date of this Lease. 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. Tenant, at the time it requests approval for a proposed Alteration, may request in writing that Landlord advise Tenant whether the Alteration or any portion of the Alteration is a Required Removable. Within 10 days after
receipt of Tenants request, Landlord shall advise Tenant in writing as to which portions of the Alteration are Required Removables.



9. Repairs and Alterations.



9.01 Tenant shall promptly provide Landlord with notice of any conditions of which it has actual knowledge 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

(e) electronic, phone and data cabling and related equipment that is installed by or for the exclusive benefit of Tenant (collectively, Cable); (f) supplemental air conditioning units, kitchens, including hot water heaters,
plumbing, and similar facilities exclusively serving Tenant; and (g) Alterations. 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, ordinary wear and tear excepted. If Tenant fails 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), 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 5% of the cost of the repairs.



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

Building; (c) will not affect the Base Building; and (d) does not require work to be performed inside the walls or above the ceiling of the Premises. 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 (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 non-Cosmetic Alterations equal to 5% of the
cost of the Alterations. Upon completion, Tenant shall furnish as-built plans for non-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 or clean the Premises (provided that Landlord shall only show the Premises during the last 12 months of the Term or during an uncured Default by Tenant) or to perform or facilitate the performance of repairs, alterations or



9



---

additions to the Premises or any portion of the Building. Except in emergencies or to provide Building services, Landlord shall provide Tenant with
reasonable prior verbal notice of entry 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.



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 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.



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) in the event of an assignment of this Lease or subletting of more than 20% of the Rentable Area of the Premises for more than 50% of the remaining Term (excluding unexercised options), recapture the portion of the Premises that Tenant is
proposing to Transfer. 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. Tenant shall pay Landlord a review fee of $1,500.00 for Landlords review of any Permitted Transfer or requested Transfer.



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 reasonable broker commissions, reasonable rent concessions, reasonable
and customary alterations, and reasonable legal expenses. 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



10



---

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.



12. Liens.



Tenant shall not permit mechanics or other liens to be placed upon the Property, 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.



13. Indemnity and Waiver of Claims.



Tenant hereby waives all claims against and releases Landlord and its
trustees, members, principals, beneficiaries, partners, officers, directors, employees, Mortgagees (defined in Section 23) and agents (the Landlord Related Parties) from all claims for any injury to or death of persons, damage to
property or business loss in any manner related to (a) Force Majeure, (b) acts of third parties not acting by, through or under Landlord, (c) the bursting or leaking of any tank, water closet, drain or other pipe, (d) the inadequacy or failure of
any security services, personnel or equipment, or (e) any matter not within the reasonable control of Landlord. 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, obligations, damages, penalties, claims, actions, costs, charges and expenses, including, without limitation, reasonable attorneys fees and other
professional fees (if and to the extent permitted by Law) (collectively referred to as 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 any damage or injury occurring in the Premises or any acts or omissions (including violations of Law) of Tenant, the Tenant Related Parties or any of Tenants transferees, contractors or licensees. Except to
the extent caused by the negligence or willful misconduct of Tenant or any Tenant Related Parties, Landlord shall indemnify, defend and hold Tenant, its trustees, members, principals, beneficiaries, partners, officers, directors, employees and
agents (Tenant Related Parties) harmless against and from all Losses which may be imposed upon, incurred by or asserted against Tenant or any of the Tenant Related Parties by any third party and arising out of or in connection
with the acts or omissions (including violations of Law) of Landlord or the Landlord Related Parties.



11

14. Insurance.



Tenant shall maintain the following insurance (Tenants Insurance): (a) Commercial General Liability Insurance applicable to the
Premises and its appurtenances providing, on an occurrence basis, an each occurrence limit of $1,000,000.00 and an aggregate limit of $2,000,000.00; (b) Property/Business Interruption Insurance written on an All Risk or Special Perils form, with
coverage for broad form water damage including earthquake sprinkler leakage, at replacement cost value and with a replacement cost endorsement covering all of Tenants business and trade fixtures, equipment, movable partitions, furniture,
merchandise and other personal property within the Premises (Tenants Property) and any Leasehold Improvements performed by or for the benefit of Tenant; (c) Workers Compensation Insurance in amounts required by Law;
and (d) Employers Liability Coverage of at least $500,000.00 per occurrence. Any company writing Tenants Insurance shall have an A.M. Best rating of not less than A-VIII. All Commercial General Liability Insurance policies shall name as
additional insureds Landlord (or its successors and assignees), the managing agent for the Building (or any successor), EOP Operating Limited Partnership, Equity Office Properties Trust and their respective members, principals, beneficiaries,
partners, officers, directors, employees, and agents, and other designees of Landlord and its successors as the interest of such designees shall appear. All policies of Tenants Insurance shall contain endorsements that the insurer(s) shall
give Landlord and its designees at least 30 days (10 days for nonpayment of premium) advance written notice of any cancellation, termination, material change or lapse of insurance. Tenant shall provide Landlord with a certificate of
insurance evidencing Tenants Insurance prior to the earlier to occur of the Commencement Date or the date Tenant is provided with possession of the Premises, and thereafter as necessary to assure that Landlord always has current certificates
evidencing Tenants Insurance. So long as the same is available at commercially reasonable rates, Landlord shall maintain so called All Risk property insurance on the Building at replacement cost value as reasonably estimated by Landlord.



15. Subrogation.



Landlord and Tenant hereby waive and shall cause their respective insurance
carriers to waive any and all rights of recovery, claims, actions or causes of action against the other for any loss or damage with respect to Tenants Property, Leasehold Improvements, the Building, the Premises, or any contents thereof,
including rights, claims, actions and causes of action based on negligence, which loss or damage is (or would have been, had the insurance required by this Lease been carried) covered by insurance.



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, 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 be made tenantable within 270 days from the date the repair is started, then either party shall have the right to terminate this Lease upon written notice to the other within 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 negligence or intentional misconduct of Tenant or any Tenant



12



---

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 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.



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 prior to the Casualty, except for modifications required by Law or any other modifications to the Common Areas deemed desirable by Landlord. Upon notice from Landlord, Tenant shall assign to Landlord (or
to any party designated by Landlord) all property insurance proceeds payable to Tenant under Tenants Insurance with respect to any Leasehold Improvements performed by or for the benefit of Tenant; 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. Within
15 days of demand, Tenant shall also pay Landlord for any additional excess costs that are determined during the performance of the repairs. Landlord shall not be liable for any inconvenience to Tenant, or injury to Tenants business resulting
in any way from the Casualty or the repair thereof. Provided that 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
portion of the Premises that is untenantable and not used by Tenant.



17.
Condemnation.



Either party may terminate this Lease if
any material part of the Premises is taken or condemned for any public or quasi-public use under Law, by eminent domain or private purchase in lieu thereof (a Taking). Landlord shall also have the right to terminate this Lease if
there is a Taking of any portion of the Building or Property which would have a material adverse effect on Landlords ability to profitably operate the remainder of the Building. The terminating party shall provide written notice of termination
to the other party within 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 20 Business Days after written notice to Tenant provided, however, if Tenants failure to comply cannot



13



---

reasonably be cured within 20 Business 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 20 Business Days and diligently pursues the cure to completion; (c) Tenant or any Guarantor becomes insolvent, makes a transfer in fraud of creditors, makes an assignment for the benefit of creditors, admits
in writing its inability to pay its debts when due or forfeits or loses its right to conduct business; (d) the leasehold estate is taken by process or operation of Law; (e) in the case of any ground floor or retail Tenant, Tenant does not take
possession of or abandons or vacates all or any portion of the Premises; or (f) Tenant is in default beyond any notice and cure period under any other lease or agreement with Landlord at the Building or Property. 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.



(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 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.



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



14



---

repossession or re-entering of all or any part of the Premises shall not relieve Tenant of its liabilities and obligations under this Lease. 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 LESSER OF (A) THE INTEREST OF LANDLORD IN THE PROPERTY, OR (B) THE EQUITY INTEREST LANDLORD WOULD HAVE IN THE PROPERTY IF THE PROPERTY WERE ENCUMBERED BY THIRD PARTY DEBT
IN AN AMOUNT EQUAL TO 70% OF THE VALUE OF THE PROPERTY. TENANT SHALL LOOK SOLELY TO LANDLORDS INTEREST IN THE PROPERTY 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.



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) equal to 150% of the sum of the Base Rent and Additional 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 15 days after notice from Landlord, Tenant shall be liable for all damages that Landlord suffers from the holdover. Notwithstanding the foregoing, Tenant shall not be liable for
consequential damages unless (1) Landlord notifies Tenant that it has entered into a lease for the Premises, and (2) Tenant fails to vacate the Premises within 30 days after the date of Landlords notice.



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



15



---

the Property, 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. Notwithstanding the foregoing, upon written request
by Tenant, Landlord will use reasonable efforts to obtain a non-disturbance, subordination and attornment agreement from Landlords then current Mortgagee on such Mortgagees then current standard form of agreement. Reasonable
efforts of Landlord shall not require Landlord to incur any cost, expense or liability to obtain such agreement, it being agreed that Tenant shall be responsible for any fee or review costs charged by the Mortgagee. Upon request of
Landlord, Tenant will execute the Mortgagees form of non-disturbance, subordination and attornment agreement and return the same to Landlord for execution by the Mortgagee. Landlords failure to obtain a non-disturbance, subordination and
attornment agreement for Tenant shall have no effect on the rights, obligations and liabilities of Landlord and Tenant or be considered to be a Default by Landlord hereunder.



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 and damage which Landlord is obligated to repair hereunder
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 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.



16

26. Miscellaneous.



26.01 This Lease shall be interpreted and enforced in accordance with the Laws of the state or commonwealth in which the Building is located 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 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.



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 Property. Upon transfer 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 brokers in connection with this Lease. Tenant shall indemnify, defend 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 agrees to indemnify, defend and hold Tenant and the Tenant Related Parties harmless
from all claims of any brokers, including the Broker, claiming to have represented Landlord in connection with this Lease. Landlord agrees to pay a brokerage commission to Richards, Barry, Joyce & Partners, LLC (Richards) in
accordance with the terms of a separate agreement between Landlord and Richards. The parties hereby acknowledge and agree that



17



---

Richards, not Landlord, shall be responsible for paying any brokerage commissions or fees to Cushman and Wakefield of Massachusetts, Inc..



26.06 Time is of the essence with respect to Tenants exercise of any
expansion, renewal 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 Tenant may
peacefully have, hold and enjoy 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.

EXPENSES AND TAXES



This Exhibit is attached to and made a part of the Lease by and between MA-RIVERVIEW/245 FIRST STREET, L.L.C., a Delaware limited liability company
(Landlord) and BITSTREAM,INC.,a Delaware corporation(Tenant) for space in the Building located at 245 First Street, Cambridge, Massachusetts 02142.



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. 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 costs and expenses incurred in each calendar year in connection with operating, maintaining, repairing, and managing the Buildings and the Property. Expenses include, without limitation: (a) all labor and labor related costs, including
wages, salaries, bonuses, taxes, insurance, uniforms, training, retirement plans, pension plans and other employee benefits; (b) 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 Building security or otherwise improve the operating efficiency of the Property; or (2) required to comply with any Laws that are enacted, or first interpreted to apply to the Property, 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. If Landlord incurs Expenses for the Building or Property together with one or more other buildings or properties, whether



1



---

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 and Property 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, 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; 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 under their respective leases.



2.03 If at any time during a calendar year the Building 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, Expenses shall, at Landlords option, be determined as if the Building had been 95% occupied and Landlord had been supplying services to 95% of the Rentable Square Footage of
the Building. 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 Property, 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 Property, taxes and assessments levied in substitution or supplementation in whole or in part of any such taxes and assessments and
the Propertys share of any real estate taxes and assessments under any reciprocal easement agreement, common area agreement or similar agreement as to the Property; (b) all personal property taxes for property that is owned by Landlord and
used in connection with the operation, maintenance and repair of the Property; 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. 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 365 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 licensed to do business in the state or commonwealth where the Property is located. Landlord agrees that Tenant may retain a third party agent to review Landlords books and
records which third party agent is not a CPA firm, so long as the third party agent retained by Tenant shall have expertise in and familiarity with general industry practice with respect to the operation of and accounting for a first class office
building and whose compensation shall in no way be contingent upon or correspond to the financial impact on Tenant resulting from the review.Tenant shall be solely responsible for all costs, expenses and fees incurred for the audit. 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 365 day period described above, Tenant shall be deemed to have



2



---

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.

| | 1.02 |  | Terms Applicable to Premises During Renewal Term.
| | ---- |  | -------------------------------------------------



| | a. |  | The initial Base Rent rate per rentable square foot for the Premises during the Renewal Term shall equal the Prevailing Market (hereinafter defined) rate per rentable square foot
for the Premises. Base Rent during the Renewal Term shall increase, if at all, in accordance with the increases assumed in the determination of Prevailing Market rate. Base Rent attributable to the Premises shall be payable in monthly installments
in accordance with the terms and conditions of Section 4 of the Lease.
| | -- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b. |  | Tenant shall pay Additional Rent (i.e. Taxes and Expenses) for the Premises during the Renewal Term in accordance with Section 4 of the Lease, and the manner and method in which
Tenant reimburses Landlord for Tenants share of Taxes and Expenses and the Base Year, if any, applicable to such matter, shall be some of the factors considered in determining the Prevailing Market rate for the Renewal Term.
| | -- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 1.03 |  | Procedure for Determining Prevailing Market. Within 30 days after receipt of Tenants Initial Renewal Notice, Landlord shall advise Tenant of the
applicable Base Rent rate for the Premises for the Renewal Term. Tenant, within 15 days after the date on which Landlord advises Tenant of the applicable Base Rent rate for the Renewal Term, shall either (i) give Landlord final binding written
notice (Binding Notice) of Tenants exercise of its Renewal Option, or (ii) if Tenant disagrees with Landlords determination, provide Landlord with written notice of rejection (the Rejection Notice).
If Tenant fails to provide Landlord with either a Binding Notice or Rejection Notice within such 15 day period, Tenants Renewal Option shall be deemed exercised upon the terms and conditions set forth herein. If Tenant provides Landlord with a
Binding Notice, Landlord and Tenant shall enter into the Renewal Amendment (as defined below) upon the terms and conditions set forth herein. If Tenant provides Landlord with a Rejection Notice, Landlord and Tenant shall work together in good faith
to agree upon the Prevailing Market rate for the Premises during the Renewal Term.
| | ---- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | When Landlord and Tenant have agreed upon the Prevailing Market rate for the Premises, such agreement shall be reflected in a written agreement between
Landlord and Tenant, whether in a letter or otherwise, and Landlord and Tenant shall enter into the Renewal Amendment in accordance with the terms and conditions hereof. Notwithstanding the foregoing, if Landlord and Tenant are unable to agree upon
the Prevailing Market rate for the Premises within 30 days after the date Tenant provides Landlord with the Rejection Notice, then either party, by written notice to the other (the Arbitration Notice) within 5 days after the
expiration of such 30 day period, shall have the right to have the Prevailing Market rate determined in accordance with the arbitration procedures described below. If Landlord and Tenant are unable to agree upon the Prevailing Market rate for the
Premises within the 30 day period described and Tenant fails to timely exercise its right to arbitrate, Tenants Renewal Option shall be deemed exercised upon the terms and conditions set forth herein.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 1.04 |  | Arbitration Procedure.
| | ---- |  | ----------------------



| | 1. |  | If Tenant provides Landlord with an Arbitration Notice, Landlord and Tenant, within 5 days after the date of the Arbitration Notice, shall each simultaneously submit to the other,
in a sealed envelope, its good faith estimate of the Prevailing Market rate for the Premises during the Renewal Term (collectively referred to as the Estimates). If the higher of such Estimates is not more than 105% of the lower
of such Estimates, then Prevailing Market rate shall be the average of the two Estimates. If the Prevailing Market rate is not resolved by the exchange of Estimates, then, within 30 days after the exchange of Estimates, Landlord and Tenant shall
each select an appraiser to determine which of the two Estimates most closely reflects the Prevailing Market rate for the Premises during the Renewal Term. Each appraiser so selected shall be certified as an MAI appraiser or as an ASA appraiser and
shall have had at least 5 years experience within the previous 10 years as a real estate appraiser working in Kendall Square area of Cambridge, Massachusetts, with working knowledge of current rental rates and practices. For purposes hereof, an
MAI appraiser means an individual who holds an MAI designation conferred by, and is an independent member of, the American Institute of Real Estate Appraisers (or its successor organization, or in the event there is no successor
organization, the organization and designation most similar), and an ASA appraiser means an individual who holds the Senior Member designation conferred by, and is an independent member of, the American Society of Appraisers (or
its successor organization, or, in the event there is no successor organization, the organization and designation most similar).
| | -- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. |  | Upon selection, Landlords and Tenants appraisers shall work together in good faith to agree upon which of the two Estimates most closely reflects the
Prevailing Market rate for the Premises. The Estimate chosen by such appraisers shall be binding on both Landlord and Tenant as the Base Rent rate for the Premises during the Renewal Term. If either Landlord or Tenant fails to appoint an appraiser
within the 30 day period referred to above, the appraiser appointed by the other party shall be the sole appraiser for the purposes hereof. If the two appraisers cannot agree upon which of the two Estimates most closely reflects the Prevailing
Market within 20 days after their appointment, then, within 10 days after the expiration of such 20 day period, the two appraisers shall select a third appraiser meeting the aforementioned criteria. Once the third appraiser (i.e. arbitrator) has
been selected as provided for above, then, as soon thereafter as practicable but in any case within 14 days, the arbitrator shall make his determination of which of the two Estimates most closely reflects the Prevailing Market rate and such Estimate
shall be binding on both Landlord and Tenant as the Base Rent rate for the Premises. If the arbitrator believes that expert advice would materially assist him, he/she may retain one or more qualified persons to provide such expert advice. The
parties shall share equally in the costs of the arbitrator and of any experts retained by the arbitrator. Any fees of any appraiser, counsel or experts engaged directly by Landlord or Tenant,
| | -- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

however, shall be borne by the party retaining such appraiser, counsel or expert.



| | 3. |  | If the Prevailing Market rate has not been determined by the commencement date of the Renewal Term, Tenant shall pay Base Rent upon the terms and conditions in effect during the
last month of the initial Term for the Premises until such time as the Prevailing Market rate has been determined. Upon such determination, the Base Rent for the Premises shall be retroactively adjusted to the commencement of the Renewal Term for
the Premises. If such adjustment results in an underpayment of Base Rent by Tenant, Tenant shall pay Landlord the amount of such underpayment within 30 days after the determination thereof. If such adjustment results in an overpayment of Base Rent
by Tenant, Landlord shall credit such overpayment against the next installment of Base Rent due under the Lease and, to the extent necessary, any subsequent installments, until the entire amount of such overpayment has been credited against Base
Rent.
| | -- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 1.05 |  | Renewal Amendment. If Tenant is entitled to and properly exercises its Renewal Option, Landlord shall prepare an amendment (the Renewal Amendment) to
reflect changes in the Base Rent, Term, Termination Date and other appropriate terms. The Renewal Amendment shall be sent to Tenant within a reasonable time after Landlords receipt of the Binding Notice or other written agreement by Landlord
and Tenant regarding the Prevailing Market rate, and Tenant shall execute and return the Renewal Amendment to Landlord within 15 days after Tenants receipt of same, but, upon final determination of the Prevailing Market rate applicable during
the Renewal Term as described herein, an otherwise valid exercise of the Renewal Option shall be fully effective whether or not the Renewal Amendment is executed.
| | ---- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 1.06 |  | Definition of Prevailing Market. For purposes of this Renewal Option, Prevailing Market shall mean the arms length fair market annual rental rate per
rentable square foot under renewal leases and amendments entered into on or about the date on which the Prevailing Market is being determined hereunder for space comparable to the Premises in the Building and office buildings comparable to the
Building in the Kendall Square area of Cambridge, Massachusetts. The determination of Prevailing Market shall take into account any material economic differences between the terms of this Lease and any comparison lease or amendment, such as rent
abatements, construction costs and other concessions and the manner, if any, in which the landlord under any such lease is reimbursed for operating expenses and taxes. The determination of Prevailing Market shall also take into consideration any
reasonably anticipated changes in the Prevailing Market rate from the time such Prevailing Market rate is being determined and the time such Prevailing Market rate will become effective under this Lease.
| | ---- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



2. PARKING.

Spaces) in, or on the roof of, the Building garage (Garage) for the use of Tenant and its employees. No deductions or allowances shall be made for days when Tenant or any of its employees does not utilize the
parking facilities or for Tenant utilizing less than all of the Spaces. Tenant shall not have the right to lease or otherwise use more than the number of reserved and unreserved Spaces set forth above. Tenant shall have the right from time to time
to reduce the number of Spaces that it leases from Landlord upon prior written notice to Landlord, and in such case Tenant shall have no further right to lease such Spaces from Landlord and relinquishes its right to use such Spaces.

| | 2.02 |  | During the initial Term, Tenant shall pay Landlord, as Additional Rent in accordance with Article 4 of the Lease, the sum of $150.00 per month, plus applicable tax thereon, if any,
for each unreserved Space leased by Tenant hereunder.

| | 2.03 |  | Except for particular spaces and areas designated by Landlord for reserved parking, all parking in the Garage and surface parking areas serving the Building shall be on an
unreserved, first-come, first-served basis.
| | ---- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2.04 |  | Landlord shall not be responsible for money, jewelry, automobiles or other personal property lost in or stolen from the Garage or the surface parking areas regardless of whether
such loss or theft occurs when the Garage or other areas therein are locked or otherwise secured. Except as caused by the negligence or willful misconduct of Landlord and without limiting the terms of the preceding sentence, Landlord shall not be
liable for any loss, injury or damage to persons using the Garage or the surface parking areas or automobiles or other property therein, it being agreed that, to the fullest extent permitted by law, the use of the Spaces shall be at the sole risk of
Tenant and its employees.

areas, if any, the Spaces and the use thereof, including, but not limited to, rules and regulations controlling the flow of traffic to and from various parking areas, the angle and direction of parking and the like. Tenant shall comply with and
cause its employees to comply with all such rules and regulations as well as all reasonable additions and amendments thereto.
| | ---- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2.06 |  | Tenant shall not store or permit its employees to store any automobiles in the Garage or on the surface parking areas without the prior written consent of Landlord. Except for
emergency repairs, Tenant and its employees shall not perform any work on any automobiles while located in the Garage or on the Property. If it is necessary for Tenant or its employees to leave an automobile in the Garage or on the surface parking
areas overnight, Tenant shall provide Landlord with prior notice thereof designating the license plate number and model of such automobile.
| | ---- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2.07 |  | Landlord shall have the right to temporarily close the Garage or certain areas therein in order to perform necessary repairs, maintenance and improvements to the Garage or the
surface parking areas, if any. If the closure is for more than 3 consecutive Business Days, Tenant shall be entitled to receive a pro rata reduction in the Additional Rent that Tenant is paying Landlord for the Spaces pursuant to paragraph 2.02
herein for each Space that Tenant is not able to use as a result of such repairs, maintenance and improvements, until the applicable Spaces are again available for Tenants use.

key for each Space that Tenant is leasing hereunder, provided that Landlord shall have the right to require Tenant or its employees to place a deposit on such access cards or keys and to pay a fee for any lost or damaged cards or keys.
| | ---- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2.10 |  | Landlord hereby reserves the right to enter into a management agreement or lease with an entity for the Garage (Garage Operator). In such event, Tenant, upon
request of Landlord, shall enter into a parking agreement with the Garage Operator and pay the Garage Operator the monthly charge established hereunder, and Landlord shall have no liability for claims arising through acts or omissions of the Garage
Operator unless caused by Landlords negligence or willful misconduct. It is understood and agreed that the identity of the Garage Operator may change from time to time during the Term. In connection therewith, any parking lease or agreement
entered into between Tenant and a Garage Operator shall be freely assignable by such Garage Operator or any successors thereto.
