Tenant covenants and agrees that it and all persons claiming by, through and under it, shall at all times abide by all reasonable rules and regulations promulgated by Landlord with respect to the use of the parking areas on the Site. The parking privileges granted herein are non-transferable except to a permitted assignee or subtenant as provided in Section 5.6. Further, Landlord assumes no responsibility whatsoever for loss or damage due to fire, theft or otherwise to any automobile(s) parked on the Site or to any personal property therein, however caused, and Tenant covenants and agrees, upon request from Landlord from time to time, to notify its officers, employees, agents and invitees of such limitation of liability. Tenant acknowledges and agrees that a license only is hereby granted, and no bailment is intended or shall be created.

Landlord reserves the right from time to time, without unreasonable interference with Tenant’s use, and provided the Number of Parking Spaces allotted to Tenant shall not be reduced: (a) to install, use, maintain, repair, replace and relocate for service to the Premises and other parts of the Building, or either, pipes, ducts, conduits, wires and appurtenant fixtures, wherever located in the Premises or Building, (b) to perform, or cause to be performed, construction in the common areas and facilities or other leased areas on the Property or in the Office Park and (c) to reduce, increase, enclose or otherwise change at any time and from time to time the size, number, location, lay-out and nature of the common areas and facilities and other tenancies and premises on the Property or in the Office Park, to create additional rentable areas through use or enclosure of common areas, and to dedicate roads within the Office Park for public use.

As soon as may be convenient after the date has been determined on which the Term commences as aforesaid, Landlord and Tenant agree to join with each other in the execution of a written Declaration, in the form of Exhibit E, in which the date on which the Term commences as aforesaid and the Term of this Lease shall be stated. If Tenant fails to execute such Declaration, the Commencement Date and Lease Term shall be as reasonably determined by Landlord in accordance with the terms of this Lease.

Tenant agrees to pay to Landlord, (1) (a) on the Rent Commencement Date (defined in Section 1.1 hereof) and thereafter monthly, in advance, on the first day of each and every calendar month during the Original Term, a sum equal to one twelfth (1/12^th) of the Annual Fixed Rent (sometimes hereinafter referred to as “fixed rent”) and (b) on the Commencement Date and thereafter monthly, in advance, on the first day of each and every calendar month during the Original Lease Term, an amount estimated by Landlord from time to time to cover Tenant’s monthly payments for electricity under Section 2.8 and (2) on the first day of each and every calendar month during the extension option period (if exercised), a sum equal to (a) one twelfth (1/12^th) of the annual fixed rent as determined in Section 9.18 for the extension option period plus (b) then applicable monthly electricity charges under Section 2.8.

Annual Fixed Rent for any partial month shall be paid by Tenant to Landlord at such rate on a pro rata basis, and, if the Rent Commencement Date is a day other than the first day of a calendar month, the first payment of Annual Fixed Rent which Tenant shall make to Landlord shall be a payment equal to a proportionate part of such monthly Annual Fixed Rent for the partial month from the Rent Commencement Date to the first day of the succeeding calendar month.

Additional Rent payable by Tenant on a monthly basis, as hereinafter provided, likewise shall be prorated, and the first payment on account thereof shall be determined in similar fashion but shall commence on the Commencement Date (excluding Additional Rent under Section 2.6 (which shall commence on January 1, 2015) and 2.7 (which shall commence on July 1, 2014)); and other provisions of this Lease calling for monthly payments shall be read as incorporating this undertaking by Tenant.

Notwithstanding that the payment of Annual Fixed Rent payable by Tenant to Landlord shall not commence until the Rent Commencement Date, Tenant shall be subject to, and shall comply with, all other provisions of this Lease as and at the times provided in this Lease.

The Annual Fixed Rent and all other charges for which provision is herein made shall be paid by Tenant to Landlord, without offset, deduction or abatement except as otherwise specifically set forth in this Lease.

“Landlord’s Operating Expenses” means the cost of operation of the Building and the Site (including, without limitation, costs associated with the operation of other portions of the Office Park benefitting and providing services to the Property as part of the Office Park as a whole, to the extent allocable to the Property) which shall exclude costs of special services rendered to tenants (including Tenant) for which a separate charge is made, but shall include, without limitation, the following: premiums for insurance carried with respect to the Building and the Site (including, without limitation, liability insurance, insurance against loss in case of fire or casualty and insurance of monthly installments of fixed rent and any Additional Rent which may be due under this Lease and other leases of space in the Building for not more than twelve (12) months in the case of both fixed rent and Additional Rent and if there be any first mortgage of the Property, including such insurance as may be required by the holder of such first mortgage); compensation and all fringe benefits, worker’s compensation insurance premiums and payroll taxes paid to, for or with respect to all persons engaged in the operating, maintaining or cleaning of the Building or Site; water, sewer, electric, gas, oil and telephone charges associated with the common areas of the Building and the Site (excluding utility charges separately chargeable to tenants); cost of building and cleaning supplies and equipment; cost of maintenance, cleaning and repairs (other than repairs not properly chargeable against income or reimbursed from contractors under guarantees); cost of snow removal and care of landscaping; cost of operating, maintaining and cleaning the cafeteria, fitness center and any shared conference facilities serving the Building; payments under service contracts with independent contractors; management fees at reasonable rates for self-managed buildings consistent with the type of occupancy and the service rendered, but in no event in excess of 3.0% of gross revenue from the Property; costs of maintaining a regional property management office in connection with the operation, management and maintenance of the Building; all costs of applying and reporting for the Building or any part thereof to seek or maintain certification under the U.S. EPA’s Energy Star® rating system, the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) rating system or a similar system or standard; and all other reasonable and necessary expenses paid in connection with the operation, cleaning and maintenance of the Building and the Site and properly chargeable against income. Landlord’s Operating Expenses shall include depreciation for capital expenditures made by Landlord during the Lease Term (i) to reduce Landlord’s Operating Expenses if Landlord shall have reasonably determined that the annual reduction in

Landlord’s Operating Expenses shall exceed depreciation therefor or (ii) to comply with applicable laws, rules, regulations, requirements, statutes, ordinances, by-laws and court decisions of all public authorities which are now or hereafter in force (the capital expenditures described in subsections (i) and (ii) being hereinafter referred to as “Permitted Capital Expenditures”), plus in the case of both (i) and (ii) an interest factor, reasonably determined by Landlord, as being the interest rate then charged for long term mortgages by institutional lenders on like properties within the locality in which the Building is located, and depreciation in the case of both (i) and (ii) shall be determined by dividing the original cost of such capital expenditure by the number of years of useful life of the capital item acquired and the useful life shall be reasonably determined by Landlord in accordance with generally accepted accounting principles and practices in effect at the time of acquisition of the capital item; provided, however, if Landlord reasonably concludes on the basis of engineering estimates that a particular capital expenditure will effect savings in other Landlord’s Operating Expenses, including, without limitation, energy related costs, and that such projected savings will, on an annual basis (“Projected Annual Savings”), exceed the annual depreciation therefor, then and in such event the amount of depreciation for such capital expenditure shall be increased to an amount equal to the Projected Annual Savings; and in such circumstance, the increased depreciation (in the amount of the Projected Annual Savings) shall be made for such period of time as it would take to fully amortize the cost of the item in question, together with interest thereon at the interest rate as aforesaid in equal monthly payments, each in the amount of 1/12^th of the Projected Annual Savings, with such payment to be applied first to interest and the balance to principal.

Notwithstanding the foregoing provisions, the following shall be excluded from Landlord’s Operating Expenses:

(7)    With the exception of the management fee described in the first paragraph of this Section 2.6 and an allocable portion of the property management office costs and expenses of Landlord or Boston Properties, the cost of any service or materials provided by any party related to Landlord, to the extent such costs exceed the reasonable cost for such service or materials absent such relationship in buildings similar to the Buildings in the vicinity of the Buildings;

(8)    Penalties and interest for late payment of any obligations of Landlord, including, without limitation, taxes, insurance, equipment leases and other past due amounts, provided that Tenant pays Operating Costs and real estate taxes timely as and when due;

(9)    Salaries or other compensation paid to employees above the grade of Regional Property Manager except that if any such employee performs a service which would have been performed by an outside consultant, the compensation paid to such employee for performing such service shall be included in Operating Expenses for the Building to the extent only that the cost of such service does not exceed the costs of such service had such service been performed by an outside consultant. Further, if and to the extent an employee performs services at the Building and other properties, such employee’s labor costs shall be reasonably allocated and only the portion reasonably allocable to the Building shall be included in Landlord’s Operating Expenses (nothing contained herein shall affect Landlord’s right to collect the management fee specifically provided for above);

(16)    All costs and expenses attributable to any hazardous wastes, substances, or materials existing as of the date of this Lease (but not any which subsequently arise, other than by reason of the acts or omissions of Landlord, its agents, contractors, or employees or other tenants of the Office Park) and/or any testing, investigation, reporting, management, maintenance, remediation or removal thereof.

(21) All general corporate overhead of Landlord or any of its agents or affiliates.

To the extent that Landlord owns other buildings in the Office Park, Landlord’s Operating Expenses that relate to the common areas of the Office Park (and not exclusively to the Building or exclusively to any other buildings within the Office Park) shall be reasonably allocated by Landlord among all such buildings in the Office Park.

In addition to the foregoing, if in any calendar year after 2014 Landlord shall provide a

service that was not provided in 2014 and the service in question is consistent with the then prevailing standards for operating and maintaining a first-class office complex, then Base Operating Expenses shall be adjusted to include 50% of the reasonable estimate of

the cost of providing such service in calendar year 2014. Further, if in any calendar year after 2014, Landlord shall cease to provide a service that was provided in 2014, then, unless the service in question is consistent with the then-prevailing standards for operating and maintaining a first-class office complex, Base Operating Expense shall be adjusted to exclude the cost of providing such services in calendar year 2014.

“Operating Expenses Allocable to the Premises” shall mean the same proportion of Landlord’s Operating Expenses for and pertaining to the Building and the Site as the Rentable Floor Area of the Premises bears to 95% of the Total Rentable Floor Area of the Building.

“Base Operating Expenses” is hereinbefore defined in Section 1.1. Base Operating Expenses shall not include (i) market-wide cost increases due to extraordinary circumstances, including but not limited to Force Majeure (as defined in Section 6.1), conservation surcharges, security concerns, boycotts, strikes, embargoes or shortages (“Temporary Cost Increase”); provided, however, that if any item(s) of Temporary Cost Increases shall continue uninterrupted beyond calendar year 2014, then the amount of such Temporary Cost Increase excluded from Base Operating Expenses with respect to such item(s) shall also be excluded from Landlord’s Operating Expenses for and with respect to any such calendar year during which such Temporary Cost Increase continues and (ii) the cost of any Permitted Capital Expenditures; provided, however, that any Permitted Capital Expenditures excluded from Base Operating Expenses shall not be included in Landlord’s Operating Expenses in any subsequent year.

“Base Operating Expenses Allocable to the Premises” means the same proportion of Base Operating Expenses for and pertaining to the Building and the Site as the Rentable Floor Area of the Premises bears to 95% of the Total Rentable Floor Area of the Building.

If with respect to any calendar year falling within the Term, or fraction of a calendar year falling within the Term at the beginning or end thereof, the Operating Expenses Allocable to the Premises for a full calendar year exceed Base Operating Expenses Allocable to the Premises, or for any such fraction of a calendar year exceed the corresponding fraction of Base Operating Expenses Allocable to the Premises then, Tenant shall pay to Landlord, as Additional Rent, the amount of such excess. Such payments shall be made at the times and in the manner hereinafter provided in this Section 2.6.

Not later than one hundred and twenty (120) days after the end of the first calendar year or fraction thereof ending December 31 and of each succeeding calendar year during the Term or fraction thereof at the end of the Term, Landlord shall render Tenant a statement in reasonable detail and according to usual accounting practices certified by a representative of Landlord, showing for the preceding calendar year or fraction thereof, as the case may be, Landlord’s Operating Expenses and Operating Expenses Allocable to the Premises (the “Annual Statement”). The Annual Statement shall also show for the preceding year or fraction thereof as the case may be the amounts of operating expenses already paid by Tenant as Additional Rent, and the amount of operating expenses

remaining due from, or overpaid by, Tenant for the year or other period covered by such statement. Within thirty (30) days after the date of delivery of such statement, Tenant shall pay to Landlord the balance of the amounts, if any, required to be paid pursuant to the above provisions of this Section 2.6 with respect to the preceding year or fraction thereof, or Landlord shall credit any amounts due from it to Tenant pursuant to the above provisions of this Section 2.6 against (i) monthly installments of fixed rent next thereafter coming due or (ii) any sums then due from Tenant to Landlord under this Lease (or refund such portion of the overpayment as aforesaid if the Term has ended, net of any sums then due from Tenant to Landlord).

In addition, Tenant shall make payments monthly on account of Tenant’s share of increases in Landlord’s Operating Expenses anticipated for the then current year at the time and in the fashion herein provided for the payment of fixed rent. The amount to be paid to Landlord shall be an amount reasonably estimated annually by Landlord to be sufficient to cover, in the aggregate, a sum equal to Tenant’s share of such increases in operating expenses for each calendar year during the Term.

Notwithstanding the foregoing, in determining the amount of Landlord’s Operating Expenses for any calendar year or portion thereof falling within the Lease Term, if less than ninety-five percent (95%) of the Total Rentable Floor Area of the Building shall have been occupied by tenants at any time during the period in question, then those components of Landlord’s Operating Expenses that vary based on occupancy for such period shall be adjusted to equal the amount such components of Landlord’s Operating Expenses would have been for such period had occupancy been ninety-five percent (95%) throughout such period.

Subject to the provisions of this Section and provided that no Event of Default of Tenant exists, Tenant shall have the right to examine the correctness of the Landlord’s Operating Expense statement or any item contained therein:

1.    Any request for examination in respect of any “Operating Year” (as defined hereinbelow) may be made by notice from Tenant to Landlord no more than one hundred eighty (180) days after the date (the “Operating Expense Statement Date”) Landlord provides Tenant an Annual Statement for such Operating Year and only if Tenant shall have fully paid such amount. Such notice shall set forth in reasonable detail the matters questioned. Any examination must be completed and the results communicated to Landlord no more than ninety (90) days after Landlord delivers to Tenant all books and records reasonably required to perform such examination. “Operating Year” shall mean a period of twelve (12) consecutive calendar months, commencing on the first day of January in each year, except that the first Operating Year of the Lease Term hereof shall be the period commencing on the Commencement Date and ending on the succeeding December 31, and the last Operating Year of the Lease Term hereof shall be the period commencing on January 1 of the calendar year in which the Lease Term ends, and ending with the date on which the Lease Term ends.

2.    Tenant hereby acknowledges and agrees that Tenant’s sole right to contest the Annual Statement shall be as expressly set forth in this Section. Tenant hereby waives any and all other rights provided pursuant to applicable laws to inspect Landlord’s books and records and/or to contest the Annual Statement. If Tenant shall fail to timely exercise Tenant’s right to inspect Landlord’s books and records as provided in this Section, or if Tenant shall fail to timely communicate to Landlord the results of Tenant’s examination as provided in this Section, with respect to any Operating Year, Landlord’s Annual Statement shall be conclusive and binding on Tenant.

3.    Landlord’s books and records pertaining to the Landlord’s Operating Expenses for the Operating Year included in the Annual Statement shall be made available to Tenant within a reasonable time after Landlord timely receives the notice from Tenant to make such examination pursuant to this Section, either electronically or during normal business hours at the offices in Massachusetts where Landlord keeps such books and records or at another location in Massachusetts, as determined by Landlord.

4.    Tenant shall have the right to make such examination no more than once in respect of any Operating Year for which Landlord has given Tenant an Annual Statement.

5.    Such examination may be made only by a qualified employee of Tenant or a qualified independent certified public accounting firm or a qualified real estate professional or firm approved by Landlord, which approval shall not be unreasonably withheld, conditioned or delayed. No examination shall be conducted by an examiner who is to be compensated, in whole or in part, on a contingent fee basis.

6.    As a condition to performing any such examination, Tenant and its examiners shall be required to execute and deliver to Landlord a commercially reasonable form of agreement, agreeing to keep confidential any information which it discovers about Landlord or the Building in connection with such examination.

7.    No subtenant shall have any right to conduct any such examination and no assignee may conduct any such examination with respect to any period during which the assignee was not in possession of the Premises.

8.    All costs and expenses of any such examination shall be paid by Tenant, provided that if such examination indicates that Landlord has overcharged Tenant for Operating Expenses for such Operating Year by more than 5%, Landlord shall reimburse Tenant for the actual, reasonable out-of-pocket costs to perform such audit.

9.    If as a result of such examination Landlord and Tenant agree that the amounts paid by Tenant to Landlord on account of the Landlord’s Operating Expenses exceeded the amounts to which Landlord was entitled hereunder, or that Tenant is entitled to a credit with respect to the Landlord’s Operating Expenses, Landlord, at its option, shall refund to Tenant the amount of such excess or apply the amount of such credit, as the case may be, within thirty (30) days after the date of such agreement. Similarly, if

Landlord and Tenant agree that the amounts paid by Tenant to Landlord on account of Landlord’s Operating Expenses were less than the amounts to which Landlord was entitled hereunder, then Tenant shall pay to Landlord, as additional rent hereunder, the amount of such deficiency within thirty (30) days after the date of such agreement.

If with respect to any full Tax Year or fraction of a Tax Year falling within the Term, Landlord’s Tax Expenses Allocable to the Premises as hereinafter defined for a full Tax Year exceed Base Taxes Allocable to the Premises, or for any such fraction of a Tax Year exceed the corresponding fraction of Base Taxes Allocable to the Premises then, on or before the thirtieth (30^th) day following receipt by Tenant of the certified statement referred to below in this Section 2.7, then Tenant shall pay to Landlord, as Additional Rent, the amount of such excess. Such payments shall be made at the times and in the manner hereinafter provided in this Section 2.7. Not later than ninety (90) days after Landlord’s Tax Expenses Allocable to the Premises are determined for the first such Tax Year or fraction thereof and for each succeeding Tax Year or fraction thereof during the Term, Landlord shall render Tenant a statement in reasonable detail certified by a representative of Landlord showing for the preceding year or fraction thereof, as the case may be, real estate taxes on the Building and the Site and abatements and refunds of any taxes and assessments. Expenditures for legal fees and for other expenses incurred in seeking the tax refund or abatement may be charged against the tax refund or abatement before the adjustments are made for the Tax Year. Said statement to be rendered to Tenant shall also show for the preceding Tax Year or fraction thereof as the case may be the amounts of real estate taxes already paid by Tenant as Additional Rent, and the amount of real estate taxes remaining due from, or overpaid by, Tenant for the year or other period covered by the statement. Within thirty (30) days after the date of delivery of the foregoing statement, Tenant shall pay to Landlord the balance of the amounts, if any, required to be paid pursuant to the above provisions of this Section 2.7 with respect to the preceding Tax Year or fraction thereof, or Landlord shall credit any amounts due from it to Tenant pursuant to the provisions of this Section 2.7 against (i) monthly installments of fixed rent next thereafter coming due or (ii) any sums then due from Tenant to Landlord under this Lease (or refund such portion of the over-payment as aforesaid if the Term has ended net of any sums then due from Tenant to Landlord).

In addition, payments by Tenant on account of increases in real estate taxes anticipated for the then current year shall be made monthly at the time and in the fashion herein provided for the payment of fixed rent. The amount so to be paid to Landlord shall be an amount reasonably estimated by Landlord to be sufficient to provide Landlord, in the aggregate, a sum equal to Tenant’s share of such increases, at least ten (10) days before the day on which such payments by Landlord would become delinquent.

To the extent that real estate taxes shall be payable to the taxing authority in installments with respect to periods less than a Tax Year, the foregoing statement shall be rendered and payments made on account of such installments.

Terms used herein are defined as follows:

municipal, or other local income, franchise, excise or similar tax, assessment, levy or charge (distinct from any now in effect in the jurisdiction in which the Property is located) measured by or based, in whole or in part, upon any such gross rents, then any and all of such taxes, assessments, levies or charges, to the extent so measured or based, shall be deemed to be included within the term “real estate taxes” but only to the extent that the same would be payable if the Site and Buildings were the only property of Landlord.

Landlord shall allocate the costs of furnishing electricity for lights and plugs and the distribution components of the heating, ventilating and air conditioning system to Tenant in accordance with the procedure contained in Exhibit H, and Tenant shall pay for such costs as provided in said Exhibit H.

The condition of the Premises upon Landlord’s delivery along with any work to be performed by either Landlord or Tenant shall be as set forth in the Work Agreement attached hereto as Exhibit B-1 and made a part hereof.

A.    Landlord shall not be liable to Tenant for any compensation or reduction of rent by reason of inconvenience or annoyance or for loss of business arising from the necessity of Landlord or its agents entering the Premises for any of the purposes in this Lease authorized, or for repairing the Premises or any portion of the Building however the necessity may occur, except if due to the negligence or willful misconduct of Landlord or its agents, contractors or employees. In case Landlord is prevented or delayed from making any repairs, alterations or improvements, or furnishing any services or performing any other covenant or duty to be performed on Landlord’s part, by reason of any cause reasonably beyond Landlord’s control, including without limitation by reason of Force Majeure (as defined in Section 6.1 hereof), Landlord shall not be liable to

Tenant therefor, nor, except as expressly otherwise provided in Article VI, shall Tenant be entitled to any abatement or reduction of rent by reason thereof, or right to terminate this Lease, nor shall the same give rise to a claim in Tenant’s favor that such failure constitutes actual or constructive, total or partial, eviction from the Premises.

Landlord reserves the right to stop any service or utility system, when necessary by reason of accident or emergency, or until necessary repairs have been completed; provided, however, that in each instance of stoppage, Landlord shall exercise reasonable diligence to eliminate the cause thereof. Except in case of emergency repairs, Landlord will give Tenant reasonable advance notice of any contemplated stoppage and will use reasonable efforts to avoid unnecessary inconvenience to Tenant by reason thereof.

B.    Notwithstanding the foregoing, upon the occurrence of any event or circumstance resulting from or caused by (x) any failure of Landlord to provide electrical, heating, ventilating, air conditioning, all elevator service to the Premises or access to the Premises, or any other service required to be provided by Landlord pursuant to the terms of this Lease that prevents Tenant from using the Premises or any portion thereof or (y) any alterations, replacements, or improvements made by Landlord to other tenant premises within the Building (any such event or circumstance described in clauses (x) or (y) above being hereinafter referred to as an “Abatement Event”), Tenant shall give Landlord notice (“Abatement Notice”) of any such Abatement Event and if such Abatement Event continues beyond the Eligibility Period (as hereinafter defined), then the Annual Fixed Rent and Tenant’s payments with respect to Operating Expenses and Taxes shall be abated entirely or reduced, as the case may be, after the expiration of the Eligibility Period for such time that Tenant continues both to be so prevented from using, and does not use, the Premises or a portion thereof, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented from using, and does not use, bears to the total Rentable Floor Area of the Premises. The term “Eligibility Period” shall mean (i) in connection with a failure by Landlord to provide required services or access to the Premises due to an event or circumstance within Landlord’s reasonable control or in connection with any alterations, replacements, or improvements made by Landlord to other tenant premises within the Building, a period of five (5) consecutive business days after Landlord’s receipt of any Abatement Notice(s) and (ii) in connection with a failure by Landlord to provide required services or access to the Premises due to an event or circumstance not within Landlord’s reasonable control, a period of fourteen (14) consecutive business days after Landlord’s receipt of any Abatement Notice(s).

because of the use, action or (where action is required hereunder or under Hazardous Materials Laws) inaction of any tenant or occupant in the Site, including Tenant, or any employee, agent or contractor of Tenant or (y) because of any use, alterations or other construction by or for Tenant or any occupant (other than any Landlord Party) of the Building (items (x) and (y) being herein collectively called the “Exclusions”). Subject to the limitations of Section 9.3 hereof, Landlord agrees to defend, indemnify, and save Tenant harmless from liability, loss and damage to persons or property and from any claims (including, without limitation, bodily injury, property damage, and environmental clean-up claims and notices of responsibility), actions, proceedings and expenses in connection therewith resulting from (1) the presence of Hazardous Materials on, at, beneath, or migrating from the Site or in the Building, except to the extent present as a result of the action of Tenant, or any employee, agent or contractor of Tenant; or (2) the failure of Landlord to fulfill its obligations under the this Section 4.3; provided, however, that in no event shall the foregoing indemnity (i) cover or in any way include the Exclusions and (ii) render Landlord liable for any loss or damage to Tenant’s Property and Landlord shall in no event be liable for indirect, consequential or punitive damages. This indemnity and hold harmless agreement shall survive the expiration or earlier termination of this Lease.

To comply with all applicable Legal Requirements now or hereafter in force that impose a duty on Landlord with respect to the common areas of the Site. Landlord hereby warrants and represents to Tenant that, to the best of Landlord’s knowledge, as of the Date of this Lease, Landlord has received no written notices from governmental authorities alleging that the Building or any portion thereof is in violation of any applicable Legal Requirements, including without limitation, (i) Title III of the Americans with Disabilities Act of 1990, or any regulations promulgated thereunder, or (ii) the regulations of the Massachusetts Architectural Access Board set forth in 521 CMR 1.00.

Building or the Additional Building, contrary to law or ordinance or liable to invalidate or increase the premiums for any insurance on the Building or its contents or liable to render necessary any alteration or addition to the Building. Further, (i) Tenant shall not, nor shall Tenant permit its employees, invitees, agents, independent contractors, contractors, assignees or subtenants to, keep, maintain, store or dispose of (into the sewage or waste disposal system or otherwise) or engage in any activity which might produce or generate asbestos, petroleum (and any breakdown product thereof), lead containing paint, PCBs, and any other substance which is or may hereafter be classified as a hazardous material, waste or substance (collectively “Hazardous Materials”), under federal, state or local laws, rules and regulations, including, without limitation, 42 U.S.C. Section 6901 et seq., 42 U.S.C. Section 9601 et seq., 42 U.S.C. Section 2601 et seq., 49 U.S.C. Section 1802 et seq. and Massachusetts General Laws, Chapter 21E and the rules and regulations promulgated under any of the foregoing, as such laws, rules and regulations may be amended from time to time (collectively “Hazardous Materials Laws”), (ii) Tenant shall promptly after becoming aware of same notify Landlord of any incident in, on or about the Premises, the Building or the Site that would require the filing of a notice under any Hazardous Materials Laws, (iii) Tenant shall comply and shall cause its employees, invitees, agents, independent contractors, contractors, assignees and subtenants to comply with each of the foregoing and (iv) Landlord shall have the right to make such inspections (including testing) as Landlord shall elect from time to time to determine that Tenant is complying with the foregoing.

To keep the Premises equipped with all safety appliances required by any public authority (it being agreed that Landlord’s Work shall include safety appliances required for Tenant to lawfully occupy the Premises) because of (i) any use made by Tenant other than normal office use, (ii) Tenant’s particular configuration of furniture within the Premises, (iii) any alterations, additions or improvements made by or on behalf of Tenant in the Premises, or (iv) any subletting of any portion of the Premises, and to procure all licenses and permits so required because of any of the foregoing items described in clauses (i), (ii), (iii), or (iv) above, it being understood that the foregoing provisions shall not be construed to broaden in any way Tenant’s Permitted Use. Landlord agrees to provide any other safety appliances so required by law (i.e., except to the extent the same are required by reason of clauses (i), (ii), (iii), or (iv) above), the cost of which shall be included in Landlord’s Operating Expenses to the extent provided in Section 2.6 above.

In addition, the merger or consolidation of Tenant into or with any other entity, or the sale of all or substantially all of its assets, shall be deemed to be an assignment within the meaning of this Section 5.6. Any assignment, mortgage, pledge, hypothecation, transfer or subletting not expressly permitted in or consented to by Landlord under Sections 5.6.1-5.6.6 shall, at Landlord’s election, be void; shall be of no force and effect; and shall confer no rights on or in favor of third parties. In addition, Landlord shall be entitled to seek specific performance of or other equitable relief with respect to the provisions hereof. The limitations of this Section 5.6 shall be deemed to apply to any guarantor(s) of this Lease.

Within thirteen (13) business days following Landlord’s receipt of Tenant’s Proposed Transfer Notice given as aforesaid (including notice given by Tenant after the effective date of such assignment pursuant to the immediately preceding provision), Landlord shall make and submit to Tenant Landlord’s consent, or refusal to consent accompanied by Landlord’s reasons therefor pursuant to Section 5.6.3, or advise Tenant in reasonable detail of the particular respects in which Tenant’s notice and/or submission is insufficient (failing which, such notice and submission shall be deemed adequate) in which case Tenant shall re-submit such notice with all required information and thereupon the thirteen (13) business day period shall again be applicable.

In the event that Landlord shall not exercise its termination rights as aforesaid, or shall fail to give any or timely notice pursuant to this Section the provisions of Sections 5.6.3, 5.6.5 and 5.6.6 shall be applicable. This Section 5.6.2 shall not be applicable to an assignment or sublease pursuant to Section 5.6.4.

Without limiting the foregoing standard, Landlord shall not be deemed to be unreasonably withholding its consent to such a proposed assignment or subleasing if:

If Landlord shall consent to the proposed assignment or subletting, as the case may be, then, in such event, Tenant may thereafter sublease or assign pursuant to Tenant’s notice, as given hereunder; provided, however, that if such assignment or sublease shall not be executed and delivered to Landlord within ninety (90) days after the date of Landlord’s consent, the consent shall be deemed null and void and the provisions of Section 5.6.1 shall be applicable.

Except in cases of statutory merger, in which case the surviving entity in the merger shall be liable as the Tenant under this Lease, Tenant shall continue to remain fully liable under this Lease, on a joint and several basis with the Permitted Transferee.

and apply the net amount collected to the rent and other charges herein reserved, but no such assignment, subletting, occupancy or collection shall be deemed a waiver of this covenant, or a waiver of the provisions of Sections 5.6 through 5.6.6 hereof, or the acceptance of the assignee, sublessee or occupant as a tenant or a release of Tenant from the further performance by Tenant of covenants on the part of Tenant herein contained, the Tenant herein named to remain primarily liable under this Lease.

(D)    The consent by Landlord to an assignment or subletting under Section 5.6.3 above, or the consummation of an assignment or subletting of right under Section 5.6.4 above, shall in no way be construed to relieve Tenant from obtaining the express consent in writing of Landlord to any further assignment or subletting, where such consent is required hereunder.

(E)    On or after the occurrence, and during the continuance, of an “Event of Default” (defined in Section 7.1), Landlord shall be entitled to one hundred percent (100%) of any Assignment/Sublease Profits.

Any space used for the purposes of this paragraph shall be unified with (e.g. not separately demised), and indistinguishable from, portions of the Premises not used for such purposes. Without limiting the generality of Section 8.1 below, Tenant shall indemnify, defend and save Landlord harmless from and against any liability, loss, cost or damage resulting from the failure of any such contractors or subcontractors to comply with the terms and conditions of this Lease, and any such failure of such contractors or subcontractors to comply with the terms and conditions of this Lease shall be deemed a failure by Tenant to comply. From time to time upon the written request of Landlord, Tenant shall identify in writing any such contractor or subcontractor occupying portions of the Premises pursuant to this Section 5.6.7.

To permit Landlord and its agents to examine the Premises at reasonable times and (except in the event of an emergency) upon reasonable prior notice and subject to Tenant’s reasonable security requirements of which Landlord has been given prior notice, if Landlord shall so elect, to make any alterations, additions or improvements contemplated by this Lease or any repairs or replacements Landlord may deem necessary in accordance with the terms and provisions of this Lease; to remove, at Tenant’s expense, any alterations, addition, signs, curtains, blinds, shades, awnings, aerials, flagpoles, or the like not consented to in writing; and to show the Premises to prospective tenants during the eleven (11) months preceding expiration of the Term and to prospective purchasers and mortgagees at all reasonable times. Landlord agrees that except in the case of an emergency, it will conduct any such entry contemplated by this Section 5.9 in such a manner so as to minimize any interference with the conduct of Tenant’s business operations in the Premises (consistent with the nature of the reason for such entry).

Not to place a load upon the Premises exceeding an average rate of 70 pounds of live load per square foot of floor area (partitions shall be considered as part of the live load); and not to move any safe, vault or other heavy equipment in, about or out of the Premises except in such manner and at such time as Landlord shall in each instance authorize; Tenant’s business machines and mechanical equipment which cause vibration or noise that may be transmitted to the Building structure or to any other space in the Building shall be so installed, maintained and used by Tenant so as to eliminate such vibration or noise.

Except as otherwise expressly provided in Section 4.6 above, to comply with all applicable Legal Requirements now or hereafter in force which shall impose a duty on Landlord or Tenant relating to or as a result of the particular manner of use or occupancy of the Premises by Tenant or any alterations or improvements performed by Tenant; provided that Tenant shall not be required to make any alterations or additions to the structure, roof, exterior and load bearing walls, foundation, structural floor slabs and other structural elements of the Building unless the same are required by such Legal Requirements as a result of or in connection with Tenant’s use or occupancy of the Premises beyond normal use of space of this kind. Tenant shall promptly pay all fines, penalties and damages that may arise out of or be imposed because of its failure to comply with the provisions of this Section 5.10.

A.    Tenant shall not make alterations and additions to Tenant’s Premises except in accordance with plans and specifications therefor first approved by Landlord, which approval shall not be unreasonably withheld, conditioned or delayed. Landlord’s determination of matters relating to aesthetic issues relating to alterations, additions or improvements which are visible outside the Premises (including, without limitation, from common lobbies within the Building) shall be in Landlord’s reasonable discretion. Without limiting such standard Landlord shall not be deemed unreasonable for withholding approval of any alterations or additions (including, without limitation, any alterations or additions to be performed by Tenant under Article III) which (a) in Landlord’s reasonable opinion will materially adversely affect any structural or exterior element of the Building, any area or element outside of the Premises, or any facility or base building mechanical system serving any area of the Building outside of the Premises, or (b) involve or affect the exterior design, size, height, or other exterior dimensions of the Building or (c) will require unusual expense to readapt the Premises to normal office use on Lease termination or expiration or increase the cost of construction or of insurance or taxes on the Building or of the services called for by Section 4.1 unless Tenant first gives assurance acceptable to Landlord for payment of such increased cost and that such readaptation will be made prior to such termination or expiration without expense to Landlord, (d) enlarge the Rentable Floor Area of the Premises, or (e) are

inconsistent, in Landlord’s reasonable judgment, with alterations satisfying Landlord’s standards for new alterations in the Building. Landlord’s review and approval of any such plans and specifications and consent to perform work described therein shall not be deemed an agreement by Landlord that such plans, specifications and work conform with applicable Legal Requirements and requirements of insurers of the Building and the other requirements of this Lease with respect to Tenant’s insurance obligations (herein called “Insurance Requirements”) nor deemed a waiver of Tenant’s obligations under this Lease with respect to applicable Legal Requirements and Insurance Requirements nor impose any liability or obligation upon Landlord with respect to the completeness, design sufficiency or compliance of such plans, specifications and work with applicable Legal Requirements and Insurance Requirements nor give right to any other parties. Further, Tenant acknowledges that Tenant is acting for its own benefit and account, and that Tenant shall not be acting as Landlord’s agent in performing any work in the Premises, accordingly, no contractor, subcontractor or supplier shall have a right to lien Landlord’s interest in the Property in connection with any such work. Within thirty (30) days after receipt of an invoice from Landlord, Tenant shall pay to Landlord as a fee for Landlord’s review of any work or plans (excluding any review respecting initial improvements performed pursuant to Article III hereof for which a fee has previously been paid but including any review of plans or work relating to any assignment or subletting), as Additional Rent, an amount equal to the sum of: (i) $150.00 per hour for time spent by Landlord’s in-house personnel (not to exceed $1,000 per project), and (ii) all reasonable third party expenses incurred by Landlord to review Tenant’s plans and Tenant’s work (Landlord hereby agreeing to cap any plan review costs (i.e., inclusive of items (i) and (ii) above) relating to interior, non-structural alterations, addition or improvements that do not impact Building systems at $6,000.00 in connection with any single request for approval). All alterations and additions shall be part of the Building unless and until Landlord shall specify the same for removal pursuant to Section 5.2. All of Tenant’s alterations and additions and installation of furnishings shall be coordinated with any work being performed by Landlord and in such manner as to maintain harmonious labor relations and not to damage the Buildings or Site or interfere with construction or operation of the Buildings and other improvements to the Site and, except for installation of furnishings, shall be performed by Landlord’s general contractor or by contractors or workers first approved by Landlord, which approval shall not be unreasonably withheld. Except for work by Landlord’s general contractor, Tenant, before its work is started, shall secure all licenses and permits necessary therefor; deliver to Landlord a statement of the names of all its contractors and subcontractors and the estimated cost of all labor and material to be furnished by them and security reasonably satisfactory to Landlord protecting Landlord against liens arising out of the furnishing of such labor and material; and cause each contractor to carry insurance in accordance with Section 8.14 herein and to deliver to Landlord certificates of all such insurance. Except with respect to purely cosmetic work, such as floor and wall coverings, Tenant shall also prepare and submit to Landlord a set of as-built plans, in both print and electronic forms, showing such work performed by Tenant to the Premises promptly after any such alterations, improvements or installations are substantially complete and promptly after any wiring or cabling for Tenant’s computer, telephone and other communications systems is installed by Tenant or

Tenant’s contractor. Without limiting any of Tenant’s obligations hereunder, Tenant shall be responsible, as Additional Rent, for the costs of any alterations, additions or improvements in or to the Building that are required in order to comply with Legal Requirements directly as a result of any work performed by Tenant. Landlord shall have the right to provide such rules and regulations relative to the performance of any alterations, additions, improvements and installations by Tenant hereunder and Tenant shall abide by all such reasonable rules and regulations of which Tenant has received advance written notice and shall cause all of its contractors to so abide including, without limitation, payment for the costs of using Building services. Tenant agrees to pay promptly when due the entire cost of any work done on the Premises by Tenant, its agents, employees, or independent contractors, and not to cause or permit any liens for labor or materials performed or furnished in connection therewith to attach to the Premises or the Buildings or the Site and immediately to discharge any such liens which may so attach. Tenant shall pay, as Additional Rent, 100% of any real estate taxes on the Property which shall, at any time after commencement of the Term, be expressly assessed by the taxing authority upon any alteration, addition or improvement to the Premises made by Tenant. Tenant acknowledges and agrees that Landlord shall be the owner of any additions, alterations and improvements in the Premises or the Building to the extent paid for by Landlord.

B.    Notwithstanding the terms of Section 5.12(A), Tenant shall have the right, without obtaining the prior consent of Landlord, to make alterations, additions or improvements to the Premises where:

provided, however, that Tenant shall, within ten (10) days prior to the making of such changes, send to Landlord plans and specifications describing the same in reasonable detail. Tenant shall not be required to remove any alterations, additions or improvements for which Landlord consent is not required under this Section 5.16.B.

Any vendors engaged by Tenant to perform services in or to the Premises including, without limitation, janitorial contractors and moving contractors shall be coordinated with any work being performed by or for Landlord and in such manner as to maintain harmonious labor relations and not to damage the Building or the Property or interfere with Building construction or operation and shall be performed by vendors first approved by Landlord, which approval shall not be unreasonably withheld.

As an inducement to Landlord to enter into this Lease, Tenant hereby represents and warrants that: (i) Tenant is not, nor is it owned or controlled directly or indirectly by, any person, group, entity or nation named on any list issued by the Office of Foreign Assets Control of the United States Department of the Treasury (“OFAC”) pursuant to Executive Order 13224 or any similar list or any law, order, rule or regulation or any Executive Order of the President of the United States as a terrorist, “Specially Designated National and Blocked Person” or other banned or blocked person (any such person, group, entity or nation being hereinafter referred to as a “Prohibited Person”); (ii) Tenant is not (nor is it owned, controlled, directly or indirectly, by any person, group, entity or nation which is) acting directly or indirectly for or on behalf of any Prohibited Person; and (iii) from and after the effective date of the above-referenced Executive Order, Tenant (and any person, group, or entity which Tenant controls, directly or indirectly) has not conducted nor will conduct business nor has engaged nor will engage in any transaction or dealing with any Prohibited Person in violation of the U.S. Patriot Act or any OFAC rule or regulation, including without limitation any assignment of this Lease or any subletting of all or any portion of the Premises or the making or receiving of any contribution of funds, goods or services to or for the benefit of a Prohibited Person in violation of the U.S. Patriot Act or any OFAC rule or regulation. In connection with the foregoing, it is expressly understood and agreed that (x) any breach by Tenant of the foregoing representations and warranties shall be deemed an immediate Event of Default by Tenant under Section 7.1 of this Lease (without the benefit of notice or grace) and shall be covered by the indemnity provisions of Section 8.1 below, and (y) the representations and warranties contained in this subsection shall be continuing in nature and shall survive the expiration or earlier termination of this Lease.

In case during the Lease Term the Building or the Site are damaged by fire or casualty and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within two hundred ten (210) days from the time that repair work would commence, Landlord may, at its election, terminate this Lease by notice given to Tenant within thirty (30) days after Landlord’s delivery to Tenant of Landlord’s estimate of

restoration, specifying the effective date of termination. The effective date of termination specified by Landlord shall not be less than thirty (30) days nor more than forty-five (45) days after the date of notice of such termination.

In case during the Term, the Premises are damaged by fire or casualty and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within two hundred ten (210) days (and/or as to special work or work which requires long lead time then if such work cannot reasonably be expected to be repaired within such additional time as is reasonable under the circumstances given the nature of the work) from the time that repair work would commence, Tenant may, at its election, terminate this Lease by notice given to Landlord within thirty (30) days after receipt of Landlord’s estimate of restoration, specifying the effective date of termination. The effective date of termination specified by Tenant shall be not less than thirty (30) days nor more than forty-five (45) days after the date of notice of such termination.

Not later than thirty (30) days after the occurrence of any casualty damage to the Building, Landlord shall cause a reputable, independent contractor, engineer, insurance adjuster or other qualified professional to prepare an estimate of the time that would be required to restore the Building as required by this Article VI, which estimate shall be delivered to Landlord and Tenant within such 30-day period. Such estimate shall provide the basis for the termination rights, if any, of Landlord and Tenant under the preceding two paragraphs.

Unless terminated pursuant to the foregoing provisions, this Lease shall remain in full force and effect following any such damage subject, however, to the following provisions.

If the Building or the Site or any part thereof are damaged by fire or other casualty and this Lease is not so terminated, or Landlord or Tenant have no right to terminate this Lease, and in any such case the holder of any mortgage which includes the Building as a part of the mortgaged premises or any ground lessor of any ground lease which includes the Site as part of the demised premises allows the net insurance proceeds to be applied to the restoration of the Building (and/or the Site), Landlord promptly after such damage and the determination of the net amount of insurance proceeds available shall use due diligence to restore the Premises and the Building in the event of damage thereto (excluding “Tenant’s Property” (as defined in Section 8.4 hereof), except as expressly provided in the immediately following paragraph of this Section 6.1) into proper condition for use and occupation and a just proportion of the Annual Fixed Rent, Tenant’s share of Operating Costs and Tenant’s share of real estate taxes and other Additional Rent according to the nature and extent of the injury to the Premises shall be abated until the Premises shall have been put by Landlord substantially into such condition except for punch list items and long lead items. Notwithstanding anything herein contained to the contrary, Landlord shall not be obligated to expend for such repair and restoration any amount in excess of the net insurance proceeds.

Notwithstanding the foregoing, if Landlord is proceeding with the restoration of the Building and the Premises in accordance with the previous paragraph, Landlord shall also restore Landlord’s Work and also any alterations, additions or improvements within the Premises that are part of Tenant’s Property (x) which have previously been approved by Landlord in accordance with the terms and provisions of this Lease and (y) with respect to which Tenant has carried “all risk” insurance covering the loss or damage in accordance with Section 8.4 below and pays the proceeds of such insurance (or an amount equivalent thereto) to Landlord within five (5) business days following Landlord’s written request); provided, however, that in no event shall Landlord be required to fund any insufficiency in the insurance proceeds (or equivalent amount) provided by Tenant with respect to such loss or damage (or to fund any of the costs of restoration in the absence of any payment by Tenant).

If neither party has previously terminated this Lease and such restoration is not completed within ten (10) months from the date of the casualty or taking, such period to be subject, however, to extension where the delay in completion of such work is due to Force Majeure, as defined hereinbelow (but in no event beyond twelve (12) months from the date of the casualty or taking), Tenant, as its sole and exclusive remedy, shall have the right to terminate this Lease at any time after the expiration of such 10-month (as extended) period until the restoration is substantially completed, such termination to take effect as of the thirtieth (30^th) day after the date of receipt by Landlord of Tenant’s notice, with the same force and effect as if such date were the date originally established as the expiration date hereof unless, within thirty (30) days after Landlord’s receipt of Tenant’s notice, such restoration is substantially completed, in which case Tenant’s notice of termination shall be of no force and effect and this Lease and the Lease Term shall continue in full force and effect. When used herein, “Force Majeure” shall mean any prevention, delay or stoppage due to governmental regulation, strikes, lockouts, acts of God, acts of war, terrorists acts, civil commotions, unusual scarcity of or inability to obtain labor or materials, labor difficulties, casualty or other causes reasonably beyond Landlord’s control or attributable to Tenant’s action or inaction.

Notwithstanding anything to the contrary contained in this Lease, if the Building or the Premises shall be substantially damaged by fire or casualty as the result of a risk not covered by the forms of casualty insurance at the time maintained by Landlord or required to be maintained by Landlord hereunder and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within ninety (90) days from the time that repair work would commence, Landlord may, at its election, terminate the Term of this Lease by notice to the Tenant given within sixty (60) days after such loss. If Landlord shall give such notice, then this Lease shall terminate as of the date of such notice with the same force and effect as if such date were the date originally established as the expiration date hereof.

If the entire Building, or such portion of the Premises as to render the balance (if reconstructed to the maximum extent practicable in the circumstances) unsuitable for Tenant’s purposes in Tenant’s reasonable business judgment, shall be taken by condemnation or right of eminent domain, Landlord or Tenant shall have the right to terminate this Lease by notice to the other of its desire to do so, provided that such notice is given not later than thirty (30) days after Tenant has been deprived of possession. If either party shall give such notice, then this Lease shall terminate as of the date that Tenant is deprived of possession with the same force and effect as if such date were the date originally established as the expiration date hereof.

Further, if (x) the entire Building shall be taken or (y) so much of the Building shall be so taken that continued operation of the Building would be uneconomic as a result of the taking, Landlord shall have the right to terminate this Lease by giving notice to Tenant of Landlord’s desire to do so not later than thirty (30) days after Tenant has been deprived of possession of the Premises (or such portion thereof as may be taken). If Landlord shall give such notice, then this Lease shall terminate as of the date that Tenant is deprived of possession with the same force and effect as if such date were the date originally established as the expiration date hereof.

Should any part of the Premises be so taken or condemned during the Lease Term hereof, and should this Lease not be terminated in accordance with the foregoing provisions, and the holder of any mortgage which includes the Premises as part of the mortgaged premises or any ground lessor of any ground lease which includes the Site as part of the demised premises allows the net condemnation proceeds to be applied to the restoration of the Building, Landlord agrees that after the determination of the net amount of condemnation proceeds available to Landlord, Landlord shall use due diligence to put what may remain of the Premises into proper condition for use and occupation as nearly like the condition of the Premises prior to such taking as shall be practicable (excluding Tenant’s Property). Notwithstanding the foregoing, Landlord shall not be obligated to expend for such repair and restoration any amount in excess of the net condemnation proceeds made available to it.

If the Premises shall be affected by any exercise of the power of eminent domain, then the Annual Fixed Rent, Tenant’s share of operating costs and Tenant’s share of real estate taxes shall be justly and equitably abated and reduced according to the nature and extent of the loss of use thereof suffered by Tenant; and in case of a taking which permanently reduces the Rentable Floor Area of the Premises, a just proportion of the Annual Fixed Rent, Tenant’s share of operating costs and Tenant’s share of real estate taxes shall be abated for the remainder of the Lease Term.

Landlord shall have and hereby reserves to itself any and all rights to receive awards made for damages to the Premises, the Buildings, the Property and the Site and the leasehold hereby created, or any one or more of them, accruing by reason of exercise of

eminent domain or by reason of anything lawfully done in pursuance of public or other authority. Tenant hereby grants, releases and assigns to Landlord all Tenant’s rights to such awards, and covenants to execute and deliver such further assignments and assurances thereof as Landlord may from time to time request.

Nothing contained herein shall be construed to prevent Tenant from prosecuting in any condemnation proceeding a claim for the value of any of Tenant’s usual trade fixtures installed in the Premises by Tenant at Tenant’s expense and for relocation and moving expenses, provided that such action and any resulting award shall not affect or diminish the amount of compensation otherwise recoverable by Landlord from the taking authority.

observed and Tenant shall fail to remedy the same within thirty (30) days after notice to Tenant specifying such neglect or failure, or if such failure is of such a nature that Tenant cannot reasonably remedy the same within such thirty (30) day period, Tenant shall fail to commence promptly to remedy the same and to prosecute such remedy to completion with diligence and continuity; or

Landlord lawfully may, immediately or at any time thereafter, and without demand or further notice terminate this Lease by notice to Tenant, specifying a date not less than ten (10) days after the giving of such notice on which this Lease shall terminate, and this Lease shall come to an end on the date specified therein as fully and completely as if such date were the date herein originally fixed for the expiration of the Lease Term (Tenant hereby waiving any rights of redemption), and Tenant will then quit and surrender the Premises to Landlord, but Tenant shall remain liable as hereinafter provided.

Amounts received by Landlord after reletting shall first be applied against such Landlord’s expenses, until the same are recovered, and until such recovery, Tenant shall pay, as of each day when a payment would fall due under this Lease, the amount which Tenant is obligated to pay under the terms of this Lease (Tenant’s liability prior to any such reletting and such recovery not in any way to be diminished as a result of the fact that such reletting might be for a rent higher than the rent provided for in this Lease); when and if such expenses have been completely recovered, the amounts received from reletting by Landlord as have not previously been applied shall be credited against Tenant’s obligations as of each day when a payment would fall due under this Lease, and only the net amount thereof shall be payable by Tenant. Further, amounts received by Landlord from such reletting for any period shall be credited only against obligations of Tenant allocable to such period, and shall not be credited against obligations of Tenant hereunder accruing subsequent or prior to such period; nor shall any credit of any kind be due for any period after the date when the term of this Lease is scheduled to expire according to its terms.

Landlord agrees to use reasonable efforts to relet the Premises after Tenant vacates the same in the event this Lease is terminated based upon an Event of Default by Tenant hereunder. The marketing of the Premises in a manner similar to the manner in which Landlord markets other premises within Landlord’s

control within the Building shall be deemed to have satisfied Landlord’s obligation to use “reasonable efforts” hereunder. In no event shall Landlord be required to (i) solicit or entertain negotiations with any other prospective tenant for the Premises until Landlord obtains full and complete possession of the Premises (including, without limitation, the final and unappealable legal right to relet the Premises free of any claim of Tenant), (ii) relet the Premises before leasing other vacant space in the Building, or (iii) lease the Premises for a rental less than the current fair market rent then prevailing for similar office space in the Building.

(ii)    For the purposes of this Article, if Landlord elects to require Tenant to pay damages in accordance with the immediately preceding paragraph, the total rent shall be computed by assuming that Tenant’s share of excess taxes, Tenant’s share of excess operating costs and Tenant’s share of excess electrical costs would be, for the balance of the unexpired Term from the date of such notice, the amount thereof (if any) for the immediately preceding annual period payable by Tenant to Landlord.

under re-letting. Tenant hereby expressly waives any and all rights of redemption granted by or under any present or future laws in the event of Tenant being evicted or dispossessed, or in the event of Landlord obtaining possession of the Premises, by reason of the violation by Tenant of any of the covenants and conditions of this Lease.

Landlord shall in no event be in default in the performance of any of Landlord’s obligations hereunder unless and until Landlord shall have failed to perform such obligations within thirty (30) days, after notice by Tenant to Landlord specifying wherein Landlord has failed to perform any such obligation, or, if such failure is of a nature that Landlord cannot reasonably remedy the same within such thirty (30) day period, Landlord shall fail to commence promptly to remedy the same within such thirty-day period and to prosecute such remedy to completion with diligence. The Tenant shall not assert any right to deduct the cost of repairs or any monetary claim against the Landlord from rent thereafter due and payable, but shall look solely to the Landlord for satisfaction of such claim.

(a)     Indemnity. To the fullest extent permitted by law, Tenant waives any right to contribution against the Landlord Parties (as hereinafter defined) and agrees to indemnify and save harmless the Landlord Parties from and against all claims of whatever nature arising from or claimed to have arisen from (i) any act, omission or negligence of the Tenant Parties (as hereinafter defined); (ii) any accident, injury or damage whatsoever caused to any person, or to the property of any person, occurring in or about the Premises from the earlier of (A) the date on which any Tenant Party first enters the Premises for any reason or (B) the Commencement Date, and thereafter throughout and until the end

of the Lease Term, and after the end of the Lease Term for so long after the end of the Lease Term as Tenant or anyone acting by, through or under Tenant is in occupancy of the Premises or any portion thereof; (iii) any accident, injury or damage whatsoever occurring outside the Premises but within the Building, or on common areas within the Office Park, where such accident, injury or damage results, or is claimed to have resulted, from the negligence or willful misconduct on the part of any of the Tenant Parties; or (iv) any breach of this Lease by Tenant. Tenant shall pay such indemnified amounts as they are incurred by the Landlord Parties. This indemnification shall not be construed to deny or reduce any other rights or obligations of indemnity that any of the Landlord Parties may have under this Lease or the common law. Notwithstanding anything contained herein to the contrary, Tenant shall not be obligated to indemnify a Landlord Party for any claims to the extent that such Landlord Party’s damages in fact result from such Landlord Party negligence or willful misconduct.

(b)     Breach. In the event that Tenant breaches any of its indemnity obligations hereunder or under any other contractual or common law indemnity: (i) Tenant shall pay to the Landlord Parties all liabilities, loss, cost, or expense (including attorney’s fees) incurred as a result of said breach; and (ii) the Landlord Parties may deduct and offset from any amounts due to Tenant under this Lease any amounts owed by Tenant pursuant to this Section 8.1(b).

(c)    No limitation. The indemnification obligations under this Section 8.1 shall not be limited in any way by any limitation on the amount or type of damages, compensation or benefits payable by or for Tenant or any subtenant or other occupant of the Premises under workers’ compensation acts, disability benefit acts, or other employee benefit acts. Tenant waives any immunity from or limitation on its indemnity or contribution liability to the Landlord Parties based upon such acts.

(d)    Subtenants and other occupants. Tenant shall require its subtenants and other occupants of the Premises to provide similar indemnities to the Landlord Parties in a form acceptable to Landlord.

(e)    Survival. The terms of this Section 8.1 shall survive any termination or expiration of this Lease.

(f)    Costs. The foregoing indemnity and hold harmless agreement shall include indemnity for all costs, expenses and liabilities (including, without limitation, attorneys’ fees and disbursements) incurred by the Landlord Parties in connection with any such claim or any action or proceeding brought thereon, and the defense thereof. In addition, in the event that any action or proceeding shall be brought against one or more Landlord Parties by reason of any such claim, Tenant, upon request from the Landlord Party, shall resist and defend such action or proceeding on behalf of the Landlord Party by counsel appointed by Tenant’s insurer (if such claim is covered by insurance without reservation) or otherwise by counsel reasonably satisfactory to the Landlord Party. The Landlord Parties shall not be bound by any compromise or settlement of any such claim, action or

proceeding without the prior written consent of such Landlord Parties, which consent shall not be unreasonably withheld.

8.1.1    Subject to the limitations in Section 9.3 and in Section 8.2 and Section 8.13 of this Article, and to the extent not resulting from any act, omission, fault, negligence or misconduct of Tenant or its contractors, licensees, invitees, agents, servants or employees, Landlord agrees to indemnify and save harmless Tenant from and against any claim by a third party arising from any injury to any person occurring in the Premises or in the Complex after the date that possession of the Premises is first delivered to Tenant and until the expiration or earlier termination of the Lease Term, to the extent such injury results from the negligence or willful misconduct of Landlord or Landlord Parties, or from any breach or default by Landlord in the performance or observance of its covenants or obligations under this Lease; provided, however, that in no event shall the aforesaid indemnity render Landlord responsible or liable for any loss or damage to fixtures, personal property or other property of Tenant, and Landlord shall in no event be liable for any indirect or consequential damages. Tenant shall provide notice of any such third party claim to Landlord as soon as practicable. Landlord shall have the right, but not the duty, to defend the claim. The provisions of this Section shall not be applicable to the holder of any mortgage now or hereafter on the Property or Building (whether or not such holder shall be a mortgagee in possession of or shall have exercised any rights under a conditional, collateral or other assignment of leases and/or rents respecting the Property or Building), except to the extent of liability insurance maintained by such holder.

Tenant agrees to use and occupy the Premises, and to use such other portions of the Building, the Site and the Office Park as Tenant is given the right to use by this Lease at Tenant’s own risk. The Landlord Parties shall not be liable to the Tenant Parties for any damage, injury, loss, compensation, or claim (including, but not limited to, claims for the interruption of or loss to a Tenant Party’s business) based on, arising out of or resulting from any cause whatsoever, including, but not limited to, repairs to any portion of the Premises, the Building, the Property or the Office Park, any fire, robbery, theft, mysterious disappearance, or any other crime or casualty, the actions of any other tenants of the Office Park or of any other person or persons, or any leakage in any part or portion of the Premises or the Building or the Property, or from water, rain or snow that may leak into, or flow from any part of the Premises or the Building or the Property, or from drains, pipes or plumbing fixtures in the Building or the Property. Any goods, property or personal effects stored or placed in or about the Premises shall be at the sole risk of the Tenant Party, and neither the Landlord Parties nor their insurers shall in any manner be held responsible therefor. The Landlord Parties shall not be responsible or liable to a Tenant Party, or to those claiming by, through or under a Tenant Party, for any loss or damage that may be occasioned by or through the acts or omissions of persons occupying adjoining premises or any part of the premises adjacent to or connecting with the Premises or any part of the Building or otherwise. The provisions of this section shall be applicable to the fullest extent permitted by law, and until the expiration or earlier

termination of the Lease Term, and during such further period as Tenant may use or be in occupancy of any part of the Premises or of the Building. Notwithstanding anything contained herein to the contrary, the provisions of this Section 8.2 shall not apply to the extent of Landlord’s negligence.

Tenant agrees to maintain in full force on or before the earlier of (i) the date on which any Tenant Party first enters the Premises for any reason or (ii) the Commencement Date, and thereafter throughout and until the end of the Lease Term, and after the end of the Lease Term for so long as Tenant or anyone acting by, through or under Tenant is in occupancy of the Premises or any portion thereafter, a policy of commercial general liability insurance, on an occurrence basis, issued on a form at least as broad as Insurance Services Office (“ISO”) Commercial General Liability Coverage “occurrence” form CG 00 01 10 01 or another Commercial General Liability “occurrence” form providing equivalent coverage. Such insurance shall include broad form contractual liability coverage, specifically covering this Lease as an insured contract. The minimum limits of liability of such insurance shall be $5,000,000 per occurrence. In addition, in the event Tenant hosts a function in the Premises, Tenant agrees to obtain, and cause any persons or parties providing services for such function to obtain, the appropriate insurance coverages as determined by Landlord (including liquor liability coverage, if applicable) and provide Landlord with evidence of the same.

Tenant shall maintain at all times during the Term of the Lease, and during such earlier time as Tenant may be performing work in or to the Premises or have property, fixtures, furniture, equipment, machinery, goods, supplies, wares or merchandise on the Premises, and containing thereafter so long as Tenant is in occupancy of any part of the Premises, business interruption insurance and insurance against loss or damage covered by the so-called “all risk” type insurance coverage with respect to Tenant’s property, fixtures, furniture, equipment, machinery, goods, supplies, wares and merchandise, and all alterations, improvements and other modifications made by or on behalf of the Tenant in the Premises (other than Landlord’s Work), and other property of Tenant located at the Premises, which are permitted to be removed by Tenant at the expiration or earlier termination of the Lease Term except to the extent paid for by Landlord (collectively “Tenant’s Property”). The business interruption insurance required by this Section 8.4 shall be in minimum amounts typically carried by prudent tenants engaged in similar operations, but in no event shall be in an amount less than the Annual Fixed Rent then in effect during any year during the Term, plus any Additional Rent due and payable for the immediately preceding year during the Term. The “all risk” insurance required by this section shall be in an amount at least equal to the full replacement cost of Tenant’s Property. In addition, during such time as Tenant is performing work in or to the Premises, Tenant, at Tenant’s expense, shall also maintain, or shall cause its contractor(s) to maintain, builder’s risk insurance for the full insurable value of such work. Landlord

and such additional persons or entities as Landlord may reasonably request shall be named as loss payees, as their interests may appear, on the property insurance policy or policies required by this Lease with respect to Tenant improvements which are paid for by Tenant and which Landlord is required to restore pursuant to the provisions of this Lease. In the event of loss or damage covered by the “all risk” insurance required by this Lease, the responsibilities for repairing or restoring the loss or damage shall be determined in accordance with Article VI. To the extent that Landlord is obligated to pay for the repair or restoration of the loss or damage covered by the policy, Landlord shall be paid the proceeds of the “all risk” insurance covering the loss or damage. To the extent Tenant is obligated to pay for the repair or restoration of the loss or damage, covered by the policy, Tenant shall be paid the proceeds of the “all risk” insurance covering the loss or damage. If both Landlord and Tenant are obligated to pay for the repair or restoration of the loss or damage covered by the policy, the insurance proceeds shall be paid to each of them in the pro rata proportion of their obligations to repair or restore the loss or damage. If the loss or damage is not repaired or restored (for example, if the Lease is terminated pursuant to Article VI), the insurance proceeds shall be paid to Landlord and Tenant in the pro rata proportion of their relative contributions to the cost of the leasehold improvements covered by the policy.

Tenant agrees to maintain in full force on or before the earlier of (i) the date on which any Tenant Party first enters the Premises for any reason or (ii) the Commencement Date, and thereafter throughout the end of the Term, and after the end of the Term for so long after the end of the Term as Tenant or anyone acting by, through or under Tenant is in occupancy of the Premises or any portion thereafter, (1) comprehensive automobile liability insurance (covering any automobiles owned or operated by Tenant at the Site) issued on a form at least as broad as ISO Business Auto Coverage form CA 00 01 07 97 or other form providing equivalent coverage; (2) worker’s compensation insurance; and (3) employer’s liability insurance. Such automobile liability insurance shall be in an amount not less than One Million Dollars ($1,000,000) for each accident. Such worker’s compensation insurance shall carry minimum limits as defined by the law of the jurisdiction in which the Premises are located (as the same may be amended from time to time). Such employer’s liability insurance shall be in an amount not less than One Million Dollars ($1,000,000) for each accident, One Million Dollars ($1,000,000) disease-policy limit, and One Million Dollars ($1,000,000) disease-each employee.

All insurance required to be maintained by Tenant pursuant to this Lease shall be maintained with responsible companies that are admitted to do business, and are in good standing in the Commonwealth of Massachusetts and that have a rating of at least “A” and are within a financial size category of not less than “Class X” in the most current Best’s Key Rating Guide or such similar rating as may be reasonably selected by Landlord. All such insurance shall: (1) be in form and content acceptable to Landlord in

its reasonable discretion; (2) be primary and noncontributory; and (3) contain an endorsement prohibiting cancellation, failure to renew, reduction of amount of insurance, or change in coverage without the insurer first giving Landlord thirty (30) days’ prior written notice (by certified or registered mail, return receipt requested, or by fax or email) of such proposed action. No such policy shall contain any deductible or self-insured retention greater than $25,000 for liability insurance and $100,000 for property insurance. Such deductibles and self-insured retentions and any deductibles shall be deemed to be “insurance” for purposes of the waiver in Section 8.13 below. Landlord reserves the right from time to time to require Tenant to obtain higher minimum amounts of insurance based on such limits as are customarily carried with respect to similar properties in the area in which the Premises are located. The minimum amounts of insurance required by this Lease shall not be reduced by the payment of claims or for any other reason. In the event Tenant shall fail to obtain or maintain any insurance meeting the requirements of this Article, or to deliver such policies or certificates as required by this Article, Landlord may, at its option, on five (5) days’ notice to Tenant, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord within five (5) days after delivery to Tenant of bills therefor.

To the fullest extent permitted by law, the commercial general liability and auto insurance carried by Tenant pursuant to this Lease, and any additional liability insurance carried by Tenant pursuant to Section 8.3 of this Lease, shall name Landlord, Landlord’s managing agent, and such other persons as Landlord may reasonably request from time to time as additional insureds with respect to liability arising out of or related to this Lease or the operations of Tenant (collectively “Additional Insureds”). Such insurance shall provide primary coverage without contribution from any other insurance carried by or for the benefit of Landlord, Landlord’s managing agent, or other Additional Insureds. Such insurance shall also waive any right of subrogation against each Additional Insured.

On or before the earlier of (i) the date on which any Tenant Party first enters the Premises for any reason or (ii) the Commencement Date, Tenant shall furnish Landlord with certificates evidencing the insurance coverage required by this Lease, and renewal certificates shall be furnished to Landlord at least annually thereafter, at least ten (10) days prior to the renewal date of each policy for which a certificate was furnished (acceptable forms of such certificates as of the date hereof for liability and property insurance, respectively, are attached as Exhibit I, however, other forms may be acceptable). Failure by the Tenant to provide the certificates or letters required by this Section 8.8 shall not be deemed to be a waiver of the requirements in this Section 8.8. Upon request by Landlord, a true and complete copy of any insurance policy required by this Lease shall be delivered to Landlord within ten (10) days following Landlord’s request.

Tenant shall require its subtenants and other occupants of the Premises to provide written documentation evidencing the obligation of such subtenant or other occupant to indemnify the Landlord Parties to the same extent that Tenant is required to indemnify the Landlord Parties pursuant to Section 8.1 above, and to maintain insurance that meets the requirements of this Article, and otherwise to comply with the requirements of this Article. Tenant shall require all such subtenants and occupants to supply certificates of insurance evidencing that the insurance requirements of this Article have been met and shall forward such certificates to Landlord on or before the earlier of (i) the date on which the subtenant or other occupant or any of their respective direct or indirect partners, officers, shareholders, directors, members, trustees, beneficiaries, servants, employees, principals, contractors, licensees, agents, invitees or representatives first enters the Premises or (ii) the commencement of the sublease. Tenant shall be responsible for identifying and remedying any deficiencies in such certificates or policy provisions.

Tenant shall not commit or permit any violation of the policies of fire, boiler, sprinkler, water damage or other insurance covering the Property and/or the fixtures, equipment and property therein carried by Landlord, or do or permit anything to be done, or keep or permit anything to be kept, in the Premises, which in case of any of the foregoing (i) would result in termination of any such policies, (ii) would adversely affect Landlord’s right of recovery under any of such policies, or (iii) would result in reputable and independent insurance companies refusing to insure the Property or the property of Landlord in amounts reasonably satisfactory to Landlord.

If, because of anything done, caused or permitted to be done, or omitted by Tenant (or its subtenant or other occupants of the Premises), the rates for liability, fire, boiler, sprinkler, water damage or other insurance on the Property and equipment of Landlord or any other tenant or subtenant in the Building shall be higher than they otherwise would be, Tenant shall reimburse Landlord and/or the other tenants and subtenants in the Building for the additional insurance premiums thereafter paid by Landlord or by any of the other tenants and subtenants in the Building which shall have been charged because of the aforesaid reasons, such reimbursement to be made from time to time on Landlord’s demand.

(a)     Required insurance. Landlord shall maintain insurance against loss or damage with respect to the Building on an “all risk” type insurance form, with customary exceptions, subject to such deductibles as Landlord may determine, in an amount equal to at least the replacement value of the Building. Landlord shall also maintain such insurance with respect to any improvements, alterations, and fixtures of Tenant located at

the Premises to the extent paid for by Landlord. The cost of such insurance shall be treated as a part of Landlord’s Operating Expenses. Such insurance shall be maintained with an insurance company selected by Landlord. Payment for losses thereunder shall be made solely to Landlord.

(b)     Optional insurance. Landlord may maintain such additional insurance with respect to the Building and the Property, including, without limitation, earthquake insurance, terrorism insurance, flood insurance, liability insurance and/or rent insurance, as Landlord may in its sole discretion elect. Landlord may also maintain such other insurance as may from time to time be required by the holder of any mortgage on the Building or Property. The cost of all such additional insurance shall also be part of the Landlord’s Operating Expenses.

(c)     Blanket and self-insurance. Any or all of Landlord’s insurance may be provided by blanket coverage maintained by Landlord or any affiliate of Landlord under its insurance program for its portfolio of properties, or by Landlord or any affiliate of Landlord under a program of self-insurance, and in such event Landlord’s Operating Expenses shall include the portion of the reasonable cost of blanket insurance or self-insurance that is allocated to the Building.

(d)     No obligation. Landlord shall not be obligated to insure, and shall not assume any liability of risk of loss for, Tenant’s Property, including any such property or work of Tenant’s subtenants or occupants, except to the extent caused solely by Landlord’s negligence or willful misconduct. Landlord will also have no obligation to carry insurance against, nor be responsible for, any loss suffered by Tenant, subtenants or other occupants due to interruption of Tenant’s or any subtenant’s or occupant’s business.

To the fullest extent permitted by law, the parties hereto waive and release any and all rights of recovery against the other, and agree not to seek to recover from the other or to make any claim against the other, and in the case of Landlord, against all “Tenant Parties” (hereinafter defined), and in the case of Tenant, against all “Landlord Parties” (hereinafter defined), for any loss or damage incurred by the waiving/releasing party to the extent such loss or damage is insured under any insurance policy required by this Lease or which would have been so insured had the party carried the insurance it was required to carry hereunder or to the extent of any greater amounts or types of insurance actually carried by such party. Tenant shall obtain from its subtenants and other occupants of the Premises a similar waiver and release of claims against any or all of Tenant or Landlord. In addition, the parties hereto (and in the case of Tenant, its subtenants and other occupants of the Premises) shall procure an appropriate clause in, or endorsement on, any insurance policy required by this Lease pursuant to which the insurance company waives subrogation. The insurance policies required by this Lease shall contain no provision that would invalidate or restrict the parties’ waiver and release of the rights of

recovery in this section. The parties hereto covenant that no insurer shall hold any right of subrogation against the parties hereto by virtue of such insurance policy.

The term “Landlord Party” or “Landlord Parties” shall mean Landlord, any affiliate of Landlord, Landlord’s managing agents for the Building, each mortgagee (if any), each ground lessor (if any), and each of their respective direct or indirect partners, officers, shareholders, directors, members, trustees, beneficiaries, servants, employees, principals, contractors, licensees, agents or representatives. For the purposes of this Lease, the term “Tenant Party” or “Tenant Parties” shall mean Tenant, any affiliate of Tenant, any permitted subtenant or any other permitted occupant of the Premises, and each of their respective direct or indirect partners, officers, shareholders, directors, members, trustees, beneficiaries, servants, employees, principals, contractors, licensees, agents, invitees or representatives.

During such times as Tenant is performing work or having work or services performed in or to the Premises, Tenant shall require its contractors, and their subcontractors of all tiers, to obtain and maintain commercial general liability, automobile, workers compensation, employer’s liability, builder’s risk, and equipment/property insurance in such amounts and on such terms as are customarily required of such contractors and subcontractors on similar projects. The amounts and terms of all such insurance are subject to Landlord’s written approval, which approval shall not be unreasonably withheld. The commercial general liability and auto insurance carried by Tenant’s contractors and their subcontractors of all tiers pursuant to this section shall name Landlord, Landlord’s managing agent, and such other persons as Landlord may reasonably request from time to time as additional insureds with respect to liability arising out of or related to their work or services (collectively “Additional Insureds”). Such insurance shall provide primary coverage without contribution from any other insurance carried by or for the benefit of Landlord, Landlord’s managing agent, or other Additional Insureds. Such insurance shall also waive any right of subrogation against each Additional Insured. Tenant shall obtain and submit to Landlord, prior to the earlier of (i) the entry onto the Premises by such contractors or subcontractors or (ii) commencement of the work or services, certificates of insurance evidencing compliance with the requirements of this section.

Failure on the part of Landlord or Tenant to complain of any action or non-action on the part of the other, no matter how long the same may continue, shall never be a waiver by Tenant or Landlord, respectively, of any of its rights hereunder. Further, no waiver at any

time of any of the provisions hereof by Landlord or Tenant shall be construed as a waiver of any of the other provisions hereof, and a waiver at any time of any of the provisions hereof shall not be construed as a waiver at any subsequent time of the same provisions. The consent or approval of Landlord or Tenant to or of any action by the other requiring such consent or approval shall not be construed to waive or render unnecessary Landlord’s or Tenant’s consent or approval to or of subsequent similar act by the other.

No payment by Tenant, or acceptance by Landlord, of a lesser amount than shall be due from Tenant to Landlord shall be treated otherwise than as a payment on account. The acceptance by Landlord of a check for a lesser amount with an endorsement or statement thereon, or upon any letter accompanying such check, that such lesser amount is payment in full, shall be given no effect, and Landlord may accept such check without prejudice to any other rights or remedies which Landlord may have against Tenant.

Except as expressly provided in this Lease, the specific remedies to which Landlord or Tenant may resort under the terms of this Lease are cumulative and are not intended to be exclusive of any other remedies or means of redress to which such party may be lawfully entitled in case of any breach or threatened breach by Tenant or Landlord, as the case may be, of any provisions of this Lease. In addition to the other remedies provided in this Lease, each of Tenant and Landlord shall be entitled to the restraint by injunction of the violation or attempted or threatened violation of any of the covenants, conditions or provisions of this Lease or to a decree compelling specific performance of any such covenants, conditions or provisions.

This Lease is subject and subordinate to all matters of record. Provided no Event of Default then exists, Tenant shall lawfully, peaceably and quietly have, hold, occupy and enjoy the Premises during the Term (exclusive of any period during which Tenant is holding over after the termination or expiration of this Lease without the consent of Landlord), without hindrance or ejection by any persons claiming by, through, or under Landlord or claiming to have title to the Premises superior to Tenant, subject, however, to the terms of this Lease; the foregoing covenant of quiet enjoyment is in lieu of any other covenant, express or implied; and it is understood and agreed that this covenant and any and all other covenants of Landlord contained in this Lease shall be binding upon Landlord and Landlord’s successors, including ground or master lessees, only with respect to breaches occurring during Landlord’s or Landlord’s successors’ respective ownership of Landlord’s interest hereunder, as the case may be.

Further, Tenant specifically agrees to look solely to Landlord's then equity interest in the Office Park at the time owned, or in which Landlord holds an interest as ground lessee, and Landlord’s interest in the proceeds of any fire or casualty insurance policy, or any liability insurance policy including, without limitation, any self-insurance (but in the case

of liability insurance and self-insurance only to the extent of an unsatisfied loss event covered by Landlord’s indemnification obligation under Section 8.1.1 hereof), or condemnation award attributable thereto, for recovery of any judgment from Landlord; it being specifically agreed that neither Landlord (original or successor), nor any beneficiary of any trust of which any person holding Landlord's interest is trustee, nor any member, manager, partner, director or stockholder, nor Landlord's managing agent, shall ever be personally liable for any such judgment, or for the payment of any monetary obligation to Tenant. The provision contained in the foregoing sentence is not intended to, and shall not, limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord or Landlord's successors in interest, or any action not involving the personal liability of Landlord (original or successor), any successor trustee to the persons named herein as Landlord, or any beneficiary of any trust of which any person holding Landlord's interest is trustee, or of any manager, member, partner, director or stockholder of Landlord or of Landlord’s managing agent to respond in monetary damages from Landlord's assets other than Landlord's equity interest aforesaid in the Office Park, but in no event shall Tenant have the right to terminate or cancel this Lease or to withhold rent or to set-off any claim or damages against rent as a result of any default by Landlord or breach by Landlord of its covenants or any warranties or promises hereunder, except in the case of a wrongful eviction of Tenant from the Premises (constructive or actual) by Landlord continuing after notice to Landlord thereof and a reasonable opportunity for Landlord to cure the same. In the event that Landlord shall be determined to have acted unreasonably in withholding any consent or approval under this Lease, the sole recourse and remedy of Tenant in respect thereof shall be to specifically enforce Landlord’s obligation to grant such consent or approval, and in no event shall the Landlord be responsible for any damages of whatever nature in respect of its failure to give such consent or approval nor shall the same otherwise affect the obligations of Tenant under this Lease or act as any termination of this Lease.

In no event shall Landlord or Tenant ever be liable to the other party for any indirect or consequential damages suffered from whatever cause; provided that the foregoing shall not limit or alter any procedural right or remedy of either party under this Lease nor shall the same apply to the obligations of Tenant with respect to any hold over by Tenant for more than thirty (30) days after the expiration or earlier termination of this Lease.

After receiving notice from any person, firm or other entity that it holds a mortgage which includes the Premises as part of the mortgaged premises, or that it is the ground lessor under a lease with Landlord, as ground lessee, which includes the Premises as a part of the demised premises, no notice from Tenant to Landlord shall be effective as to such holder or ground lessor unless and until such notice is given to such holder or ground lessor, and the curing of any of Landlord’s defaults by such holder or ground lessor within a reasonable time thereafter (including a reasonable time to obtain possession of the premises if the mortgagee or ground lessor elects to do so) shall be treated as performance by Landlord. For the purposes of this Section 9.4 or Section 9.14,

the term “mortgage” includes a mortgage on a leasehold interest of Landlord (but not one on Tenant’s leasehold interest). If any mortgage is listed on Exhibit J then the same shall constitute notice from the holder of such mortgage for the purposes of this Section 9.4. Further no Annual Fixed Rent or Additional Rent may be paid by Tenant more than thirty (30) days in advance except with the prior written consent of all holder(s) of such mortgages and ground leases, and any such payment without such consent shall not be binding on such holder(s).

With reference to any assignment by Landlord of Landlord’s interest in this Lease, or the rents payable hereunder, conditional in nature or otherwise, which assignment is made to the holder of a mortgage or ground lease on property which includes the Premises, Tenant agrees:

In no event shall the acquisition of title to the Building and the land on which the same is located by a purchaser which, simultaneously therewith, leases the entire Building or such land back to the seller thereof be treated as an assumption by such purchaser-lessor, by operation of law or otherwise, of Landlord’s obligations hereunder, but Tenant shall look solely to such seller-lessee, and its successors from time to time in title, for performance of Landlord’s obligations hereunder subject to the provisions of Section 9.3 hereof. In any such event, this Lease shall be subject and subordinate to the lease to such purchaser provided that such purchaser agrees to recognize the right of Tenant to use and occupy the Premises upon the payment of rent and other charges payable by Tenant under this Lease and the performance by Tenant of Tenant’s obligations hereunder and provided that Tenant agrees to attorn to such purchaser. For all purposes, such seller-lessee, and its successors in title, shall be the landlord hereunder unless and until Landlord’s position shall have been assumed by such purchaser-lessor.

No act or thing done by Landlord during the Lease Term shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept such surrender shall be valid,

unless in writing signed by Landlord. No employee of Landlord or of Landlord’s agents shall have any power to accept the keys of the Premises prior to the termination of this Lease. The delivery of keys to any employee of Landlord or of Landlord’s agents shall not operate as a termination of the Lease or a surrender of the Premises.

(A)    Tenant warrants and represents that Tenant has not dealt with any broker in connection with the consummation of this Lease other than the Broker; and in the event any claim is made against the Landlord relative to dealings by Tenant with brokers other than the Broker, Tenant shall defend the claim against Landlord with counsel of Tenant’s selection first approved by Landlord (which approval will not be unreasonably withheld) and save harmless and indemnify Landlord on account of loss, cost or damage which may arise by reason of such claim.

(B)    Landlord warrants and represents that Landlord has not dealt with any broker in connection with the consummation of this Lease other than the Broker; and in the event any claim is made against the Tenant relative to dealings by Landlord with brokers other than the Broker, Landlord shall defend the claim against Tenant with counsel of Landlord’s selection first approved by Tenant (which approval will not be unreasonably withheld) and save harmless and indemnify Tenant on account of loss, cost or damage which may arise by reason of such claim. Landlord agrees that it shall be solely responsible for the payment of brokerage commissions to the Broker for the Original Term of this Lease.

If any term or provision of this Lease, including but not limited to any waiver of contribution or claims, indemnity, obligation, or limitation of liability or of damages, or the application thereof to any person or circumstance shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term or provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby, and each term and provision of this Lease shall be valid and be enforced to the fullest extent permitted by law.

The obligations of this Lease shall run with the land, and except as herein otherwise provided, the terms hereof shall be binding upon and shall inure to the benefit of the successors and assigns, respectively, of Landlord and Tenant and, if Tenant shall be an individual, upon and to his heirs, executors, administrators, successors and assigns. The reference contained to successors and assigns of Tenant is not intended to constitute a consent to subletting or assignment by Tenant.

Tenant agrees not to record the within Lease, but each party hereto agrees, on the request of the other, to execute a so-called Notice of Lease or short form lease in form recordable and complying with applicable law and reasonably satisfactory to both Landlord’s and Tenant’s attorneys. In no event shall such document set forth rent or other charges payable by Tenant under this Lease; and any such document shall expressly state that it is executed pursuant to the provisions contained in this Lease, and is not intended to vary the terms and conditions of this Lease.

Notwithstanding that Tenant is a public company, Tenant agrees that this Lease and the terms contained herein will be treated as strictly confidential and except as required by law, including, without limitation, as required to satisfy filing requirements of a public company (or except with the written consent of Landlord) Tenant shall not disclose the same to any third party except for Tenant’s partners, lenders, accountants and attorneys who have been advised of the confidentiality provisions contained herein and agree to be bound by the same. In the event Tenant is required by law to provide this Lease or disclose any of its terms, Tenant shall give Landlord prompt notice of such requirement prior to making disclosure so that Landlord may seek an appropriate protective order; provided, however that the requirements set forth in this sentence shall not apply in connection with any disclosure to the extent required to satisfy filing requirements of a public company. If failing the entry of a protective order Tenant is compelled to make disclosure, Tenant shall only disclose portions of the Lease which Tenant is required to disclose and will exercise reasonable efforts to obtain assurance that confidential treatment will be accorded to the information so disclosed.

Whenever, by the terms of this Lease, notice shall or may be given either to Landlord or to Tenant, such notice shall be in writing (and no inference shall be drawn from the fact that certain provisions of this Lease require “written notice” where others simply require “notice”) and shall be sent by overnight commercial courier (which obtains a signature upon delivery) or by registered or certified mail postage or delivery charges prepaid, as the case may be:

If intended for Landlord, addressed to Landlord at the address set forth in Article I of this Lease (or to such other address or addresses as may from time to time hereafter be designated by Landlord by like notice) with a copy to Landlord, Attention: Regional General Counsel.

If intended for Tenant, addressed to Tenant at the address set forth in Article I of this Lease except that from and after the Commencement Date the address of Tenant shall be the Premises (or to such other address or addresses as may from time to time hereafter be designated by Tenant by like notice) with a copy to Tenant, Attention: General Counsel, and a copy to Goodwin Procter LLP, Exchange Place, 53 State Street, Boston, MA 02109 Attention: Eric M. Labbe, Esquire.

Except as otherwise provided herein, all such notices shall be effective when received; provided, that (i) if receipt is refused, notice shall be effective upon the first occasion that such receipt is refused, (ii) if the notice is unable to be delivered due to a change of address of which no notice was given, notice shall be effective upon the date such delivery was attempted, (iii) if the notice address is a post office box number, notice shall be effective the day after such notice is sent as provided hereinabove or (iv) if the notice is to a foreign address, notice shall be effective two (2) days after such notice is sent as provided hereinabove.

Where provision is made for the attention of an individual or department, the notice shall be effective only if the wrapper in which such notice is sent is addressed to the attention of such individual or department.

Any notice given by an attorney on behalf of Landlord or by Landlord’s managing agent shall be considered as given by Landlord and shall be fully effective. Any notice given by an attorney on behalf of Tenant shall be considered as given by Tenant and shall be fully effective.

Time is of the essence with respect to any and all notices and periods for giving notice or taking any action thereto under this Lease.

Employees or agents of Landlord have no authority to make or agree to make a lease or any other agreement or undertaking in connection herewith. The submission of this document for examination and negotiation does not constitute an offer to lease, or a reservation of, or option for, the Premises, and this document shall become effective and binding only upon the execution and delivery hereof by both Landlord and Tenant. All negotiations, considerations, representations and understandings between Landlord and Tenant are incorporated herein and may be modified or altered only by written agreement between Landlord and Tenant, and no act or omission of any employee or agent of Landlord or Tenant shall alter, change or modify any of the provisions hereof. Landlord and Tenant hereby represents and warrants to the other that all necessary action has been taken to enter this Lease and that the person signing this Lease on behalf of Landlord and Tenant has been duly authorized to do so.

The titles of the Articles throughout this Lease are for convenience and reference only, and the words contained therein shall in no way be held to explain, modify, amplify or aid in the interpretation, construction or meaning of the provisions of this Lease. Wherever in this Lease it is stated that any approval, consent, or the like shall not be unreasonably withheld, such statement shall be read as meaning that the same shall not be unreasonably withheld, delayed, or conditioned.

This Lease shall be subject and subordinate to any mortgage now or hereafter on the Site or the Building, or both, and to each advance made or hereafter to be made under any mortgage, and to all renewals, modifications, consolidations, replacements and extensions thereof and all substitutions therefor provided that the holder of such mortgage agrees to recognize the rights of Tenant under this Lease (including, without limitation, the right to use and occupy the Premises) upon the payment of rent and other charges payable by Tenant under this Lease and the performance by Tenant of Tenant’s obligations hereunder as provided in a commercially reasonable form of subordination, non-disturbance and attornment agreement provided to Tenant and executed and delivered by such mortgagee. In the event that any mortgagee or its respective successor in title shall succeed to the interest of Landlord, then, this Lease shall nevertheless continue in full force and effect and Tenant shall and does hereby agree to attorn to such mortgagee or successor and to recognize such mortgagee or successor as its landlord. If any holder of a mortgage which includes the Premises, executed and recorded prior to the date of this Lease, shall so elect, this Lease and the rights of Tenant hereunder, shall be superior in right to the rights of such holder, with the same force and effect as if this Lease had been executed, delivered and recorded, or a statutory notice hereof recorded, prior to the execution, delivery and recording of any such mortgage. The election of any such holder shall become effective upon either notice from such holder to Tenant in the same fashion as notices from Landlord to Tenant are to be given hereunder or by the recording in the appropriate registry or recorder’s office of an instrument in which such holder subordinates its rights under such mortgage to this Lease.

Landlord represents and warrants that there is no mortgage or ground lease encumbering the Building or the Site as of the date of this Lease.

(A)    Recognizing that either party may find it necessary to establish to third parties, such as accountants, banks, potential or existing mortgagees, potential purchasers or the like, the then current status of performance hereunder, each party, on the request of the other made from time to time, will promptly furnish to the other, or any existing or potential holder of any mortgage encumbering the Premises, the Building, the Site and/or the Property or any potential purchaser of the Premises, the Building, the Site and/or the Property (each an “Interested Party”), a statement of the status of any matter pertaining to this Lease, including, without limitation, acknowledgments that (or the extent to which) each party is in compliance with its obligations under the terms of this Lease. Any such status statement delivered by Tenant pursuant to this Section 9.15(A) may be relied upon by any Interested Party.

(B)    For so long as Tenant is a publicly-traded entity and timely files its financial statements with the Securities and Exchange Commission under and with Forms 10Q and 10K, Tenant shall have no obligation to deliver financial statements to Landlord. In the

event that Tenant ceases to be a publicly-traded entity for reporting purposes, Tenant shall deliver to Landlord, or any Interested Party designated by Landlord, upon Landlord’s written request given not more than once in any 12-month period, Tenant’s most recent audited financial statements of Tenant, or if Tenant does not have its financials audited, Tenant shall provide financial statements certified by the appropriate accounting or finance officer of Tenant, including, but not limited to, a balance sheet, income statement and cash flow statements which financial statements shall include sufficient detail and information for Landlord to assess Tenant’s financial condition. Such financial statements may, as requested by Landlord, include financial statements for the past three (3) years (if available), and any such status statement and/or financial statement delivered by Tenant pursuant to this Section 8.16(B) may be relied upon by any Interested Party. Landlord and any Interested Party to whom Tenant directly provides such information shall keep any non-public information provided by Tenant pursuant to this Section 9.15(B) confidential, and shall not disclose the same other than (i) on a need to know basis to Landlord’s officers, employees and consultants (or to any of the Interested Parties), all of whom shall be instructed to keep such information confidential, or (ii) to the extent required by applicable law or by any administrative, governmental or judicial proceeding.

If Tenant shall at any time default in the performance of any obligation under this Lease, after notice to Tenant thereof and expiration of any applicable cure period, Landlord shall have the right, but shall not be obligated, to enter upon the Premises and to perform such obligation notwithstanding the fact that no specific provision for such substituted performance by Landlord is made in this Lease with respect to such default. In performing such obligation, Landlord may make any payment of money or perform any other act. All sums so paid by Landlord (together with interest at the rate of two and one-half percentage points over the then prevailing prime rate in Boston as set by Bank of America, N.A., or its successor (but in no event greater than the maximum rate permitted by applicable law) and all costs and expenses in connection with the performance of any such act by Landlord, shall be deemed to be Additional Rent under this Lease and shall be payable to Landlord immediately on demand. Landlord may exercise the foregoing rights without waiving any other of its rights or releasing Tenant from any of its obligations under this Lease.

Any holding over by Tenant after the expiration of the term of this Lease shall be treated as a tenancy at sufferance and shall be on the terms and conditions as set forth in this Lease, as far as applicable except that, for the first thirty (30) days of any such holdover Tenant shall pay as a use and occupancy charge an amount equal to the greater of (x) 150% of the Annual Fixed Rent and Additional Rent calculated (on a daily basis) at the highest rate payable under the terms of this Lease, or (y) the fair market rental value of the Premises; and thereafter, Tenant shall pay as a use and occupancy charge an amount

equal to the greater of (x) 200% of the Annual Fixed Rent and Additional Rent calculated (on a daily basis) at the highest rate payable under the terms of this Lease, or (y) the fair market rental value of the Premises, terminating on the day on which Tenant vacates the Premises in accordance with the requirements of this Lease. In addition, Tenant shall save Landlord, its agents and employees harmless and will exonerate, defend and indemnify Landlord, its agents and employees from and against any and all damages which Landlord may suffer on account of Tenant’s hold-over in the Premises after the expiration or prior termination of the term of this Lease; provided, however, that Tenant shall not be liable for indirect or consequential damages suffered or incurred by Landlord as a result of such hold-over for the first 30 days of such hold-over. Nothing in the foregoing nor any other term or provision of this Lease shall be deemed to permit Tenant to retain possession of the Premises or hold over in the Premises after the expiration or earlier termination of the Lease Term. All property which remains in the Building or the Premises after the expiration or termination of this Lease shall be conclusively deemed to be abandoned and may either be retained by Landlord as its property or sold or otherwise disposed of in such manner as Landlord may see fit. If any part thereof shall be sold, then Landlord may receive the proceeds of such sale and apply the same, at its option against the expenses of the sale, the cost of moving and storage, any arrears of rent or other charges payable hereunder by Tenant to Landlord and any damages to which Landlord may be entitled under this Lease and at law and in equity.

(A)    On the conditions (which conditions Landlord may waive by written notice to Tenant) that both at the time of exercise of the option to extend and as of the commencement of the Extended Term in question (i) there exists no Event of Default (defined in Section 7.1), (ii) this Lease is still in full force and effect, and (iii) Tenant has neither assigned this Lease nor sublet more than thirty percent (30%) the Premises (except for an assignment or subletting permitted without Landlord’s consent under Section 5.6.4 hereof), Tenant shall have the right to extend the Term hereof upon all the same terms, conditions, covenants and agreements herein contained (except for the Annual Fixed Rent which shall be adjusted during the option period as hereinbelow set forth) for one (1) period of five (5) years as hereinafter set forth. The option period is sometimes herein referred to as the “Extended Term.” Notwithstanding any implication to the contrary Landlord has no obligation to make any additional payment to Tenant in respect of any construction allowance or the like or to perform any work to the Premises as a result of the exercise by Tenant of such option.

(B)    If Tenant desires to exercise said option to extend the Term, then Tenant shall give notice (the “Exercise Notice”) to Landlord, not earlier than fifteen (15) months nor later than twelve (12) months prior to the expiration of the Term of this Lease exercising such option to extend. Within ten (10) business days after Landlord's receipt of the Exercise Notice, Landlord shall provide Landlord's quotation to Tenant of a proposed annual rent for the Extended Term (“Landlord's Rent Quotation”). If at the expiration of thirty (30) days after the date when Landlord provides such quotation to Tenant (the “Negotiation

Period”), Landlord and Tenant have not reached agreement on a determination of an annual rental for the Extended Term and executed a written instrument extending the Term of this Lease pursuant to such agreement, then Tenant shall have the right, for thirty (30) days following the expiration of the Negotiation Period, to make a request to Landlord for a broker determination (the “Broker Determination”) of the Prevailing Market Rent (as defined in Exhibit K) for the Extended Term, which Broker Determination shall be made in the manner set forth in Exhibit K. If Tenant timely shall have requested the Broker Determination, then the Annual Fixed Rent for the Extended Term shall be the Prevailing Market Rent as determined by the Broker Determination. If Tenant does not timely request the Broker Determination, then Annual Fixed Rent during the Extended Term shall be equal to Landlord's Rent Quotation.

(C)    Upon the giving of the Exercise Notice by Tenant to Landlord exercising Tenant's option to extend the Lease Term in accordance with the provisions of Section B above, then this Lease and the Lease Term hereof shall automatically be deemed extended for the Extended Term without the necessity for the execution of any additional documents, except that Landlord and Tenant agree to enter into an instrument in writing setting forth the Annual Fixed Rent for the Extended Term as determined in the relevant manner set forth in this Section 9.18; and in such event all references herein to the Lease Term or the term of this Lease shall be construed as referring to the Lease Term, as so extended, unless the context clearly otherwise requires, and except that there shall be no further option to extend the Lease Term.

9.19    Security Deposit

Tenant agrees that the Security Deposit shall be paid upon execution and delivery of this Lease, and that Landlord shall hold the same, throughout the term of this Lease (including any extension thereof), as security for the performance by Tenant of all obligations on the part of Tenant to be kept and performed. Landlord shall have the right from time to time without prejudice to any other remedy Landlord may have on account thereof, to apply such deposit, or any part thereof, to Landlord’s damages arising from any Event of Default. If Landlord so applies all or any portion of such deposit, Tenant shall within seven (7) days after notice from Landlord deliver cash to Landlord in an amount sufficient to restore such deposit to the full amount stated in Section 1.1. While Landlord holds such deposit, Landlord shall have no obligation to pay interest on the same and shall have the right to commingle the same with Landlord’s other funds. If Landlord conveys Landlord’s interest under this Lease, the deposit, or any part thereof not previously applied, may be turned over by Landlord to Landlord’s grantee, and, if so turned over, Tenant agrees to look solely to such grantee for proper application of the deposit in accordance with the terms of this Section 9.19, and the return thereof in accordance herewith.

Tenant shall have the right, upon not less than ten (10) days prior written notice to Landlord, to provide such security deposit in the form of an irrevocable, unconditional, negotiable letter of credit (the “Letter of Credit”). The Letter of Credit shall (i) be issued by and drawn on a bank reasonably approved by Landlord and at a minimum having a long term issuer credit rating from Standard and Poor’s Professional Rating Service of A or a comparable rating from Moody’s Professional Rating Service, (ii) be substantially in the form attached hereto as Exhibit G, (iii) permit one or more draws thereunder to be made accompanied only by certification by Landlord or Landlord’s managing agent that pursuant to the terms of this Lease, Landlord is entitled to draw upon such Letter of Credit, (iv) permit transfers at any time without charge, and (v) provide that any notices to Landlord be sent to the notice address provided for Landlord in this Lease. If the credit rating for the issuer of such Letter of Credit falls below the standard set forth in (i) above or if the financial condition of such issuer changes in any other material adverse way, Landlord shall have the right to require that Tenant provide a substitute letter of credit that complies in all respects with the requirements of this Section, and Tenant’s failure to provide the same within thirty (30) days following Landlord’s written demand therefor shall entitle Landlord to immediately draw upon the Letter of Credit. Any such Letter of Credit shall be for a term of two (2) years (or for one (1) year if the issuer thereof regularly and customarily only issues letters of credit for a maximum term of one (1) year) and shall in either case provide for automatic renewals through the date which is ninety (90) days subsequent to the scheduled expiration of this Lease (as the same may be extended) or if the issuer will not grant automatic renewals, the Letter of Credit shall be renewed by Tenant each year and each such renewal shall be delivered to and received by Landlord not later than sixty (60) days before the expiration of the then current Letter of Credit (herein called a “Renewal Presentation Date”). In the event of a failure to so deliver any such renewal Letter of Credit on or before the applicable Renewal

Presentation Date, Landlord shall be entitled to present the then existing Letter of Credit for payment and to receive the proceeds thereof, which proceeds shall be held as Tenant’s security deposit, subject to the terms of this Section 9.19. Any failure or refusal to honor the Letter of Credit shall be at Tenant’s sole risk and shall not relieve Tenant of its obligation hereunder with regard to the security deposit. Upon the receipt by Landlord of a Letter of Credit meeting the requirements set forth herein, Landlord shall return to Tenant any cash security deposit then being held by Landlord, and thereafter such Letter of Credit shall be held by Landlord in accordance with the terms and conditions of this Section 9.19 as security for Tenant’s obligations hereunder.

Landlord shall return $100,000.00 of the Security Deposit to Tenant so that the remainder of such Security Deposit shall be $300,000.00 (or if such deposit is in the form of a Letter of Credit, as provided below, Landlord shall either exchange the Letter of Credit for a Letter of Credit delivered by Tenant or accept an amendment to such Letter of Credit, in either case which reduces the amount secured by the Letter of Credit by $100,000.00 and otherwise in strict conformity with the requirements herein) on the second anniversary of the Commencement Date; provided that (i) no Event of Default has occurred under this Lease and remains uncured as of such second anniversary, and (ii) Landlord has not applied the Security Deposit, or any portion thereof, to Landlord's damages arising from any Event of Default, whether or not Tenant has restored the amount so applied by Landlord.

If Tenant believes that it has satisfied all the conditions precedent to a reduction in the amount of the Security Deposit, then it shall request such reduction in writing to Landlord, which request shall certify to Landlord that all such conditions have been satisfied. If Landlord determines that all of the aforesaid conditions are met, the Security Deposit shall be so reduced in accordance with this Section 9.19. No Letter of Credit shall automatically reduce, but any reduction in the amount thereof shall require Landlord’s prior written notice to the issuer of the Letter of Credit of the reduced amount. Promptly after Landlord’s receipt of Tenant’s request for a reduction as described above, Landlord shall determine whether such a reduction is permitted in accordance with this Section 9.19, and if it is, Landlord shall notify the issuer of the Letter of Credit of the amount to which the Letter of Credit shall be reduced.

Tenant not then being in default and having performed all of its obligations under this Lease, including the payment of all Annual Fixed Rent, Landlord shall return the deposit, or so much thereof as shall not have theretofore been applied in accordance with the terms of this Section 9.19, to Tenant on the expiration or earlier termination of the term of this Lease (as the same may have been extended) and surrender possession of the Premises by Tenant to Landlord in the condition required in the Lease at such time.

Neither the holder of any mortgage nor the lessor in any ground lease on property which includes the Premises shall ever be responsible to Tenant for the return or application of any such deposit, whether or not it succeeds to the position of Landlord hereunder, unless such deposit shall have been received in hand by such holder or ground lessor.

If Landlord shall not have received any payment or installment of Annual Fixed Rent or Additional Rent (the “Outstanding Amount”) on or before the date on which the same first becomes payable under this Lease (the “Due Date”), the amount of such payment or installment shall incur a late charge equal to the sum of: (a) five percent (5%) of the Outstanding Amount for administration and bookkeeping costs associated with the late payment and (b) interest on the Outstanding Amount from the Due Date through and including the date such payment or installment is received by Landlord, at a rate equal to the lesser of (i) the rate announced by Bank of America, N.A. (or its successor) from time to time as its prime or base rate (or if such rate is no longer available, a comparable rate reasonably selected by Landlord), plus two percent (2%), or (ii) the maximum applicable legal rate, if any. Such interest shall be deemed Additional Rent and shall be paid by Tenant to Landlord upon demand.

Landlord agrees to waive the late charge due hereunder for the first late payment by Tenant under this Lease, provided that Landlord receives such payment from Tenant within five (5) business days after notice to Tenant of such nonpayment.

Each and every payment and expenditure, other than Annual Fixed Rent, shall be deemed to be Additional Rent or additional rent hereunder, whether or not the provisions requiring payment of such amounts specifically so state, and shall be payable, unless otherwise provided in this Lease, within thirty (30) days after written demand by Landlord, and in the case of the non-payment of any such amount, Landlord shall have, in addition to all of its other rights and remedies, all the rights and remedies available to Landlord hereunder or by law in the case of non-payment of Annual Fixed Rent. Unless expressly otherwise provided in this Lease, the performance and observance by Tenant of all the terms, covenants and conditions of this Lease to be performed and observed by Tenant shall be at Tenant’s sole cost and expense. Except as otherwise provided in Section 2.6 in connection with Tenant’s exercise of its audit rights, if Tenant has not objected to any statement of Additional Rent which is rendered by Landlord to Tenant within one (1) year after Landlord has rendered the same to Tenant, then the same shall be deemed to be a final account between Landlord and Tenant not subject to any further dispute. In the event that Tenant shall seek Landlord’s consent or approval under this Lease, then Tenant shall reimburse Landlord, upon demand, as Additional Rent, for all reasonable out of pocket costs and expenses, including legal and architectural costs and expenses, incurred by Landlord in processing such request, whether or not such consent or approval shall be given. Notwithstanding anything in this Lease to the contrary, if Landlord or any affiliate of Landlord has elected to qualify as a real estate investment trust (“REIT”), any service required or permitted to be performed by Landlord pursuant to this Lease, the charge or cost of which may be treated as impermissible tenant service income under the laws governing a REIT, may be performed by a taxable REIT

subsidiary that is affiliated with either Landlord or Landlord’s property manager, an independent contractor of Landlord or Landlord’s property manager (the “Service Provider”). If Tenant is subject to a charge under this Lease for any such service, then, at Landlord’s direction, Tenant will pay such charge either to Landlord for further payment to the Service Provider or directly to the Service Provider, and, in either case, (i) Landlord will credit such payment against Additional Rent due from Tenant under this Lease for such service, and (ii) such payment to the Service Provider will not relieve Landlord from any obligation under the Lease concerning the provisions of such service.

A.    To induce Landlord to enter into this Lease, Tenant hereby waives any right to trial by jury in any action, proceeding or counterclaim brought by either Landlord or Tenant on any matters whatsoever arising out of or any way connected with this Lease, the relationship of the Landlord and the Tenant, the Tenant’s use or occupancy of the Premises and/or any claim of injury or damage, including but not limited to, any summary process eviction action.

B.    To induce Tenant to enter into this Lease, Landlord hereby waives any right to trial by jury in any action, proceeding or counterclaim brought by either Landlord or Tenant on any matters whatsoever arising out of or any way connected with this Lease, the relationship of the Landlord and the Tenant, the Tenant’s use or occupancy of the Premises and/or any claim of injury or damage, including but not limited to, any summary process eviction action.

This Lease shall be governed exclusively by the provisions hereof and by the law of the Commonwealth of Massachusetts, as the same may from time to time exist.

Tenant agrees that no diminution of light, air or view by any structure (inside or outside the Building) which may hereafter be erected or modified (whether or not by Landlord) shall entitle Tenant to any reduction of rent hereunder, result in any liability of Landlord to Tenant, or in any other way affect this Lease.

Tenant shall not use the name of the Building or Office Park for any purpose other than as the address of the business conducted by Tenant in the Premises without the written consent of Landlord. Landlord reserves the right to change the name of the Building and/or the Office Park at any time in its sole discretion by written notice to Tenant and Landlord shall not be liable to Tenant for any loss, cost or expense on account of any such change of name.

Subject to the provisions of this Section 9.26, and subject to (i) any and all rights of tenants in the Office Park to lease the Available Space (as hereinafter defined) pursuant to the express expansion or extension provisions in their respective leases and (ii) Landlord’s right to renew or extend the lease of an existing tenant (whether or not they have renewal or extension options in their lease), if Landlord determines that at any time during this Lease any space on the third (3^rd) floor south wing of the Building contiguous to the Premises (“Potential ROFO Space” and shown on Exhibit L attached hereto and incorporated herein by reference) becomes available for reletting (“Available Space”), and provided that (i) no Event of Default has occurred and remains uncured under this Lease, (ii) Tenant has not assigned this Lease or sublet all or any portion of the Premises, except as permitted under Section 5.6.4, and (iii) this Lease is still in full force and effect, Landlord agrees not to enter into a lease or leases to lease the Available Space without delivering to Tenant a notice (“Landlord’s ROFO Notice”) containing the date, as reasonably determined by Landlord, on which Landlord anticipates that the Available Space in question shall be available for delivery to Tenant, a plan showing the Available Space (and indicating the rentable square footage thereof), the Annual Fixed Rent, Base Operating Expenses and Base Taxes for the Available Space in question, and any work allowance, free rent period or other material business terms upon which Landlord is willing to lease such Available Space. If Tenant wishes to exercise Tenant’s right of first offer, Tenant shall have the right to do so by delivering notice to Landlord of Tenant’s desire to lease the entire space described in Landlord’s ROFO Notice (it being agreed that Tenant has no right to lease less than such entire space) on the terms provided herein (“Tenant’s Acceptance Notice”), provided Landlord receives Tenant’s Acceptance Notice not later than that date which is ten (10) days after the date of Landlord’s ROFO Notice, time being of the essence. If Tenant shall deliver a timely Tenant’s Acceptance Notice, then this Lease shall automatically be deemed amended to incorporate the Available Space into the Premises on such terms and conditions, without the necessity for the execution of any additional documents; however, Landlord and Tenant agree within fifteen (15) days of Landlord’s receipt of Tenant’s Acceptance Notice (or fifteen (15) days from the Broker Determination of Annual Fixed Rent, if Tenant requests the same pursuant to the terms hereof) to execute and deliver an amendment to this Lease prepared by Landlord incorporating the Available Space into the Premises upon all of the same terms and conditions in this Lease, except that: (i) the Annual Fixed Rent, which shall be as set forth in Landlord’s ROFO Notice (or as determined by Broker Determination, if so requested by Tenant pursuant to the terms hereof); (ii) all other terms and conditions set forth in Landlord’s ROFO Notice shall be applicable to the Available Space; (iii) the lease term as to the Available Space shall be coterminous with the Term (as it may be extended pursuant to Section 9.18 of this Lease or as it may be earlier terminated under this Lease); and (iv) those provisions of this Lease which conflict with the specific terms set forth in Landlord’s ROFO Notice shall be not applicable to the Available Space. If for any reason Tenant shall not so exercise such right within such period, time being of the essence in

respect to such exercise, Landlord shall be free to lease such Available Space to a third party.

In the event Tenant desires to exercise its right of first offer, but Tenant disagrees with Landlord’s determination of the Annual Fixed Rent for the Available Space, Tenant shall provide Landlord with Tenant’s Acceptance Notice meeting the requirements set forth above within the time period specified above, but Tenant’s Acceptance Notice shall also request a Broker Determination of the Prevailing Market Rent (as defined in Exhibit K) for the Available Space, which Broker Determination shall be made in the manner set forth in Exhibit K. In any event, Tenant’s delivery of Tenant’s Acceptance Notice shall be deemed to be the irrevocable exercise by Tenant of its right of first offer subject to and in accordance with the provisions of this Section 9.26.

Notwithstanding anything contained in this Section 9.26 to the contrary, in no event shall Landlord be obligated to offer the Available Space in question for lease to Tenant, or to deliver a Landlord’s ROFO Notice to Tenant with respect thereto, nor shall Tenant have the right to lease the Available Space in question under the terms set forth herein or otherwise, or to receive a Landlord’s ROFO Notice with respect thereto, if Landlord determines that possession of the Available Space will not be available for delivery to Tenant until on or after that date which is twelve (12) months prior to the end of the original Term hereof, unless Tenant, having the right to do so, has theretofore properly exercised its right to extend the original Term of this Lease pursuant to the provisions of Section 9.18 above.

Landlord hereby confirms that Private Healthcare Systems is the only current tenant whose leases contain expansion rights with respect to all or a portion of the Potential ROFO Space.

EXECUTED as a sealed instrument in two or more counterparts each of which shall be deemed

to be an original.

Section 3.1    Preparation of the Premises

(A)    Tenant shall accept the First Additional Premises in their as-is condition without any obligation on the Landlord’s part to perform any additions, alterations, improvements, demolition or other work therein or pertaining thereto, except as otherwise expressly set forth in the Lease. Landlord, however, agrees to deliver the First Additional Premises in broom clean condition free of all debris and personal property and free of all tenants and parties in possession.

(B)    The plans and specifications for the Tenant’s work on the First Additional Premises (the “Tenant’s Work”) have been approved by Landlord and are attached hereto as Exhibit B (the “Plans”). Landlord’s approval of the Plans hereby constitutes approval under Section 5.12 of the Lease for Tenant’s alterations to the Premises. Notwithstanding Section 5.12 of the Lease, Tenant shall not be responsible for payment as Additional Rent of any fees in connection with Landlord’s review of the Plans and Tenant’s Work; provided, however, that Landlord reserves the right to engage a structural engineer for consultation in connection with the File Room shown on the Plans if Landlord deems necessary and Tenant shall be responsible for reimbursing Landlord for reasonable and actual fees associated with the same. Tenant shall have the right to change, modify or amend such Plans, subject to (i) the reasonable approval by Landlord of such changes, modifications or amendments, and (ii) to the payment of fees and costs stipulated in Section 5.12 of the Lease in connection with Landlord’s review of such amendments to the Plans. All such future approvals, or disapprovals with supporting specific reasons, for subsequent submittals of corrections or changes, shall be provided to Tenant within five (5) business days of Landlord’s receipt.

    

(C)    Tenant, at its sole cost and expense, shall promptly, and with all due diligence, perform Tenant’s Work as set forth on the Plans, and, in connection therewith, Tenant shall obtain all necessary governmental permits and approvals for Tenant’s Work. All of Tenant’s Work shall be performed in a good and workmanlike manner, strictly in accordance with the Plans, and in compliance with all Legal Requirements and all Insurance Requirements. Tenant shall have Tenant’s Work performed by contractors, reasonably approved by Landlord, which contractors shall provide to Landlord such insurance as required by Section 8.14 of the Lease. Landlord hereby acknowledges that it has approved the contractors listed on Exhibit C, attached hereto, to act as Tenant’s contractor with respect to Tenant’s Work. Landlord shall have the right, in accordance with Section 5.12 of the Lease, to provide such reasonable rules and regulations relative to the performance of Tenant’s Work and any other work which the Tenant may perform under the Lease and Tenant shall abide by all such reasonable rules and regulations and shall cause all of its contractors to so abide including, without limitation, payment for the costs of using Building electrical services and, if Tenant’s Work is performed other than during normal Building business hours, the cost of building engineer during such overtime hours. It shall be Tenant’s obligation to obtain a certificate of occupancy or other like governmental approval for the use and occupancy of the First Additional

Premises to the extent required by law, and Tenant shall not occupy the First Additional Premises for the conduct of business until and unless it has obtained such approval and has submitted to Landlord a copy of the same together with waivers of lien from all of Tenant’s contractors in form adequate for recording purposes. Tenant shall also prepare and submit to Landlord promptly after Tenant’s Work is substantially complete a set of as-built plans in both print and electronic forms showing the work performed by Tenant to the Premises including, without limitation, any wiring or cabling installed by Tenant or Tenant’s contractor for Tenant’s computer, telephone and other communication systems.

(D)    Tenant acknowledges that Tenant is acting for its own benefit and account and that Tenant will not be acting as Landlord’s agent in performing any Tenant Work, accordingly, no contractor, subcontractor or supplier shall have a right to lien Landlord’s interest in the Property in connection with any work.

(E)    Landlord shall provide to Tenant a special allowance equal to Three Hundred Eighty One Thousand Five Hundred Ten and 00/100 Dollars ($381,510.00) (being the product of (i) $10.00 and (ii) the Rentable Floor Area of the Premises (the “Tenant Allowance”)).

The Tenant Allowance shall be used and applied by Tenant solely toward the following (collectively, “Costs”): (i) the costs of labor and materials incurred in the performance of Tenant’s Work, any other work contemplated by the Plans, any other work to integrate the First Additional Premises into the Existing Premises, and any other work approved by the Landlord on the Premises, and (ii) architectural and engineering fees and expenses and the cost of telecommunications and AV wiring incurred in connection with the design of Tenant’s Work, provided, however, that such costs shall be payable from Tenant’s Allowance up to an aggregate amount not to exceed $44,505.00.

As a condition precedent to the disbursement of any payments on account of the Tenant Allowance, Tenant shall deliver to Landlord a certificate signed by Tenant specifying the total amount of all Costs of Tenant’s Work, including architectural and engineering fees and expenses, and identifying all design professionals, consultants, contractors, service providers, subcontractors and suppliers involved with Tenant’s Work (the “Tenant’s Costs Certificate”). Tenant shall promptly notify Landlord in writing of any material change in the total amount of all Costs of Tenant’s Work as reflected in Tenant’s Costs Certificate.

(F)    For the purposes hereof, a “Requisition” shall mean written documentation (including invoices from all applicable Tenant’s design professionals, consultants, contractors, service providers, subcontractors and suppliers, and such other documentation as Landlord’s mortgagee may reasonably request) showing in reasonable detail the Tenant’s Work completed to date and the cost of all of the items, services and work covered thereby.

Each Requisition shall be accompanied by (i) evidence reasonably satisfactory to Landlord that all of the items, services and work covered by such Requisition have been

fully paid by Tenant, (ii) executed lien waivers (partial or final, as applicable) in the forms attached hereto as Exhibit D from all persons or entities that might have a lien as a result of performing any such services or work or furnishing any such items, (iii) a certificate signed by Tenant’s architect certifying that the Tenant’s Work reflected in such Requisition has been completed substantially in accordance with the approved Plans, and (iv) a certificate signed by Tenant certifying that the amount of the such Requisition does not exceed the cost of the items, services and work covered thereby. Landlord shall have the right, upon reasonable advance notice to Tenant, to inspect Tenant’s books and records relating to each Requisition in order to verify the amount thereof. Tenant shall submit Requisition(s) no more often than once every thirty (30) days.

Provided and on condition that, as of the date on which Tenant submits to Landlord any Requisition (together with all required supporting documentation) (i) Tenant has delivered Tenant’s Costs Certificate to Landlord, (ii) Tenant has submitted such Requisition to Landlord not later than the date that is Three Hundred Sixty-Five (365) days after the Effective Date, (iii) there exists no Event of Default, and (iv) there are no liens (unless bonded to the reasonable satisfaction of Landlord) against Tenant’s interest in the Lease or against the Building or the Site arising out of Tenant’s Work or any litigation in which Tenant is a party, then Landlord shall pay the Costs shown on such Requisition within thirty (30) days after Landlord’s receipt thereof; provided, however, that in no event shall Landlord have any obligation to pay or otherwise fund any amount in excess of the Tenant Allowance.

(G)    Notwithstanding anything to the contrary herein contained:

(i)    In addition to the other requirements applicable to Requisitions generally, as set forth in Section 8(F) above, it is understood and agreed that Landlord shall have no obligation to pay Tenant’s final Requisition, unless and until (a) Tenant has delivered to Landlord a final set of record drawings for Tenant’s Work, (b) Tenant has delivered to Landlord a certificate of substantial completion signed by Tenant’s general contractor and (c) a certificate of occupancy has been approved for issuance by the applicable governmental authority respecting the First Additional Premises.

(ii)    Landlord shall in no event be deemed, by undertaking to pay the Tenant Allowance or otherwise, to have assumed any obligations, in whole or in part, of Tenant to any design professionals, consultants, contractors, vendors, service providers, subcontractors, suppliers, workers, materialmen or other third parties.

(iii)    Except with respect to work and/or materials previously paid for by Tenant, as evidenced by paid invoices and written lien waivers provided to Landlord, Landlord shall have the right (but not the obligation) to have portions of the Tenant Allowance paid to directly to Tenant’s design professionals, consultants, contractors, service providers, subcontractors or suppliers.

(iv)    In the event that Costs are less than the Tenant Allowance, Tenant shall not be entitled to any payment or credit, nor shall there be any application of the same toward Annual Fixed Rent or Additional Rent owed by Tenant under the Lease.

(B)    Landlord warrants and represents that Landlord has not dealt with any broker in connection with the consummation of this First Amendment, other than the Broker, and in the event any claim is made against Tenant relative to dealings by Landlord with brokers, Landlord shall defend the claim against Tenant with counsel of Landlord’s selection first approved by Tenant (which approval will not be unreasonably withheld) and save harmless and indemnify Tenant on account of loss, cost or damage which may arise by reason of such claim. Landlord agrees that it shall be solely responsible for the payment of brokerage commissions to the Broker for the First Extended Term as further outlined in a separate agreement between Landlord and the Broker.

14.    Each of Landlord and Tenant hereby represents and warrants to the other that all     necessary action has been taken to enter this First Amendment and that the person signing     this First Amendment on its behalf has been duly authorized to do so.

    

EXECUTED as of the date and year first above written.

THIRD AMENDMENT TO LEASE dated as of this 7th day of December, 2015 (the “Effective Date”), by and between BP BAY COLONY LLC, a Delaware limited liability company (“Landlord”) and AMAG PHARMACEUTICALS, INC., a Delaware corporation (“Tenant”).

By Lease dated June 10, 2013 (the “Original Lease”), Landlord did lease to Tenant and Tenant did hire and lease from Landlord certain premises containing 32,217 square feet of rentable floor area (the “Rentable Floor Area of the Original Premises”) on the third (3rd) floor of the building (the “Building”) known as and numbered Bay Colony Corporate Center, 1100 Winter Street, Waltham, Massachusetts (referred to herein as the “Original Premises”).

By First Amendment to Lease dated as of March 24, 2015 (the “First Amendment”), Landlord and Tenant (i) increased the size of the Original Premises by adding thereto an additional 5,934 square feet of rentable floor area (the “Rentable Floor Area of the First Additional Premises”) located on the third (3rd) floor of the North Wing of the Building, which space is shown on Exhibit A attached to the First Amendment (the “First Additional Premises” and together with the Original Premises, the “Existing Premises”) and (ii) extended the Term of the Original Lease for a period of one (1) year, upon all of the same terms and conditions contained in the Original Lease except as otherwise provided in the First Amendment to Lease. The Rentable Floor Area of the Original Premises, together with the Rentable Floor Area of the First Additional Premises, contains 38,151 square feet of rentable floor area (collectively referred to herein as the “Rentable Floor Area of the Existing Premises”).

By Second Amendment to Lease dated as of November 3, 2015 (the “Second Amendment”), Landlord did lease to Tenant and Tenant did hire and lease from Landlord, on a temporary basis, certain premises containing 6,452 square feet of rentable floor area on the second (2^nd) floor of the Building, which space is shown on Exhibit A attached to the Second Amendment (the “Temporary Premises”), upon all of the same terms and conditions set forth in the Lease except as otherwise provided in the Second Amendment.

Landlord and Tenant have agreed (i) to increase the size of the Existing Premises by adding thereto an additional 21,154 square feet of rentable floor area (the “Rentable Floor Area of the Second Additional Premises”) located on the second (2^nd) floor of the Building, which space is shown on Exhibit A attached hereto and made a part hereof (the “Second Additional Premises”), (ii) to modify the Temporary Premises Termination Date as defined in the Second Amendment, and (iii) to extend the Term of the Lease for a period of five (5) year(s) from the Second Additional Premises Rent Commencement Date (as hereinafter defined), upon all of the same terms and conditions contained in the Lease except as otherwise provided in this Third Amendment to Lease (the “Third Amendment”).

Landlord and Tenant are entering into this instrument to set forth said leasing of the Second Additional Premises and said modification of the Temporary Premises Termination Date, to extend the Term of the Lease and to amend the Lease.

NOW THEREFORE, in consideration of One Dollar ($1.00) and other good and valuable consideration in hand this date paid by each of the parties to the other, the receipt and sufficiency of which are hereby severally acknowledged, and in further consideration of the mutual promises herein contained, Landlord and Tenant hereby agree to and with each other as follows:

1.    Effective as of the date (the “Second Additional Premises Commencement Date”) upon which Landlord delivers the Second Additional Premises to Tenant with the Landlord’s Work (as hereinafter defined) completed, the Second Additional Premises shall constitute a part of the “Tenant’s Premises” demised to Tenant under the Lease, so that the “Tenant’s Premises” and, by definition the “Premises” (as defined in Sections 1.1 and 2.1 of the Lease), shall include both the Second Additional Premises and the Existing Premises. Landlord shall use commercially reasonable efforts to complete Landlord’s Work by January 1, 2016 (the “Estimated Completion Date”). If Landlord shall have failed substantially to complete Landlord’s Work on or before the date which is thirty (30) days subsequent to the Estimated Completion Date (which date shall be extended automatically for such periods of time as Landlord is prevented from proceeding with or completing the same by reason of Force Majeure as defined in Section 6.1 or any Tenant Delay (as defined below) without limiting Landlord's other rights on account thereof), the Annual Fixed Rent and Tenant’s payments on account of operating expenses and real estate taxes shall be abated by one (1) day for each day beyond the date which is thirty (30) days subsequent to the Estimated Completion Date (as so extended) that Landlord thus fails to substantially complete the Landlord’s Work. The foregoing rent abatement right shall be Tenant’s sole and exclusive remedy at law or in equity or otherwise for Landlord’s failure to substantially complete the Landlord’s Work within the time periods set forth above. For the purposes of this paragraph, a “Tenant Delay” is a delay that is caused by (A) Tenant’s failure to timely respond to any request from Landlord, Landlord’s architect, Landlord’s contractor and/or Landlord’s Construction Representative within the time periods set forth in Section 7 of this Third Amendment or in the Work Agreement attached as Exhibit B-1 to the Original Lease, or (B) any other delays caused by Tenant, Tenant’s contractors, architects, engineers, or anyone else engaged by Tenant in connection with the preparation of the Second Additional Premises for Tenant’s occupancy, including, without limitation, utility companies and other entities furnishing communications, data processing or other service, equipment, or furniture which continues for more than two (2) business days after notice from Landlord.

2.    (A)    The Term of the Lease, which but for this Second Amendment is scheduled to expire on November 30, 2019, is hereby extended for a period (the "Second Extended Term") commencing on December 1, 2019 and expiring on the date which is five (5) years after the Second Additional Premises Rent Commencement Date (as defined in Section 3 below), unless sooner terminated or extended in accordance with the provisions of the Lease, upon all the same terms and conditions contained in the Lease as herein amended.

(B)    Landlord and Tenant acknowledge that Tenant shall continue to have the right to extend the Term of the Lease for one (1) period of five (5) years upon the expiration of the Second Extended Term in accordance with the terms and conditions set forth in Section 9.18 of the Lease (as amended by Section 2 of the First Amendment) except that (i) all references to the “Extended Term” shall be replaced with “Third Extended Term” and (ii) Exhibit K attached to the Lease is hereby deleted in its entirety and replaced with Exhibit B attached hereto and made a part hereof.

(C)    The Term of the Lease for the Existing Premises and the Second Additional Premises shall be coterminous. Accordingly, the extension option contained in Section 9.18 of the Lease (as amended by Section 2 of the First Amendment and as amended hereby) shall apply to the Existing Premises and the Second Additional Premises collectively and not to either such space independently.

3.    (A)    (i)    Annual Fixed Rent for the Existing Premises through November 30, 2019 shall continue to be payable as set forth in the Lease.

“One hundred and seventy-eight (178) (being three (3) spaces per 1,000 square feet of Rentable Floor Area of the Premises).”

7.    Section 3.1 of the Lease, as it pertains to the Second Additional Premises only, shall be deleted in its entirety and shall be replaced with the following Section 3.1:

“Section 3.1    Preparation of the Premises

3.1    Tenant’s Work

Landlord of such changes, modifications or amendments, and (ii) the payment of costs stipulated in Subsection 3.1(B) of the Lease in connection with Landlord’s review of such amendments to the Plans. All such future approvals, or disapprovals with supporting specific reasons, for subsequent submittals of corrections or changes, shall be provided to Tenant within seven (7) business days of Landlord’s receipt.

(B)    Tenant, at its sole cost and expense, shall promptly, and with all due diligence, perform Tenant’s Work as set forth on the Plans, and, in connection therewith, the Tenant shall obtain all necessary governmental permits and approvals for Tenant’s Work. All of Tenant’s Work shall be performed strictly in accordance with the Plans and in accordance with applicable Legal Requirements (as defined in Section 3.1(C) hereof) and Insurance Requirements (as defined in Section 5.12 of the Lease). Tenant shall have Tenant’s Work performed by Chapman Construction or another contractor or contractors, reasonably approved by Landlord, which contractors shall provide to Landlord such insurance as required by Section 8.14 of the Lease. Landlord shall have the right to provide reasonable rules and regulations relative to the performance of Tenant’s Work and any other work which the Tenant may perform under the Lease and Tenant shall abide by all such reasonable rules and regulations and shall cause all of its contractors to so abide including, without limitation, payment for the costs of using Building services; provided, however, that in the event of a conflict between said rules and regulations and the terms of the Lease, the terms of the Lease shall govern. It shall be Tenant’s obligation to obtain a certificate of occupancy or other like governmental approval for the use and occupancy of the Second Additional Premises to the extent required by law, and Tenant shall not occupy the Second Additional Premises for the conduct of business until and unless it has obtained such approval and has submitted to Landlord a copy of the same together with waivers of lien from all of Tenant’s contractors in form adequate for recording purposes. Tenant shall also prepare and submit to Landlord promptly after Tenant’s Work is substantially complete a set of as-built plans in both print and electronic forms showing the work performed by Tenant to the Second Additional Premises, but excluding any wiring or cabling installed by Tenant or Tenant’s contractor for Tenant’s computer, telephone and other communication systems. Within thirty (30) days after receipt of an invoice from Landlord, Tenant shall pay to Landlord, as Additional Rent, an amount equal to the reasonable third party expenses incurred by Landlord to review Tenant’s Plans and Tenant’s Work (Landlord hereby agreeing to cap any plan review costs relating to interior, non-structural alterations, additions or improvements that do not impact Building systems at $6,000.00 in connection with any single request for approval).

(C)    All construction work required or permitted by the Lease shall be done in a good and workmanlike manner and in compliance with all applicable laws, ordinances, rules, regulations, statutes, by-laws, court decisions, and orders and requirements of all public authorities (“Legal Requirements”) and all Insurance Requirements (as defined in Section 5.12 of the Lease); provided, however, that Tenant shall have no obligation to make any changes to the Building (other than the Premises) related to Tenant’s Work, except to the extent such changes are necessitated solely by Tenant’s Work. All of Tenant’s work shall be coordinated with any work being performed by or for Landlord and in such manner as to maintain harmonious labor relations. Each party may inspect the work of the other at reasonable times and shall promptly give notice of observed defects.

Each party authorizes the other to rely in connection with design and construction upon approval and other actions on the party’s behalf by any Construction Representative of the party named herein or any person hereafter designated in substitution or addition by notice to the party relying. Landlord hereby appoints Luke Bowen as Landlord’s Construction Representative, and Tenant hereby appoints Nathan McBride as Tenant’s Construction Representative. Tenant acknowledges that Tenant is acting for its own benefit and account and that Tenant will not be acting as Landlord’s agent in performing any Tenant Work, accordingly, no contractor, subcontractor or supplier shall have a right to lien Landlord’s interest in the Property in connection with any work. Except to the

extent to which Tenant shall have given Landlord notice of any defects or any errors and omissions in Landlord’s Work not later than the end of the eleventh (11th) full calendar month next beginning after the Second Additional Premises Commencement Date, Tenant shall be deemed conclusively to have approved Landlord’s Work and shall have no claim that Landlord has failed to perform any of Landlord’s Work. Landlord agrees to correct or repair at its expense items which are then incomplete or do not conform to the requirements of Landlord’s Work and as to which, in either case, Tenant shall have given notice to Landlord, as aforesaid.

(D)    Landlord shall provide to Tenant a special allowance equal to Eight Hundred Forty-Six Thousand One Hundred Sixty and 00/100 Dollars ($846,160.00) (being the product of (i) $40.00 and (ii) the Rentable Floor Area of the Second Additional Premises (the “Tenant Allowance”)).

The Tenant Allowance shall be used and applied by Tenant solely toward the following (collectively, “Costs”): (i) the costs of labor and materials incurred in the performance of Tenant’s Work, any other work contemplated by the Plans, any other work to integrate the Second Additional Premises into the Existing Premises, and any other work approved by the Landlord on the Premises, and (ii) architectural and engineering fees and expenses and the cost of telecommunications and AV wiring, in each case incurred in connection with Tenant’s Work, provided, however, that the costs in this subsection (ii) shall be payable from Tenant’s Allowance up to an aggregate amount not to exceed $169,232.00.

As a condition precedent to the disbursement of any payments on account of the Tenant Allowance, Tenant shall deliver to Landlord a certificate signed by Tenant specifying the total amount of all Costs of Tenant’s Work, including architectural and engineering fees and expenses, and identifying all design professionals, consultants, contractors, service providers, subcontractors and suppliers involved with Tenant’s Work (the “Tenant’s Costs Certificate”). Tenant shall promptly notify Landlord in writing of any material change in the total amount of all Costs of Tenant’s Work as reflected in Tenant’s Costs Certificate.

(E)    For the purposes hereof, a “Requisition” shall mean written documentation (including invoices from all applicable Tenant’s design professionals, consultants, contractors, service providers, subcontractors and suppliers, and such other documentation as the mortgagee of Landlord, if any, may reasonably request) showing in reasonable detail the Tenant’s Work completed to date and the cost of all of the items, services and work covered thereby.

Each Requisition shall be accompanied by (i) evidence reasonably satisfactory to Landlord that all of the items, services and work covered by such Requisition have been fully paid by Tenant, (ii) executed lien waivers (partial or final, as applicable) in the forms attached hereto as Exhibit E from all persons or entities that might have a lien as a result of performing any such services or work or furnishing any such items, (iii) a certificate signed by Tenant’s architect certifying that the Tenant’s Work reflected in such Requisition has been completed substantially in accordance with the approved Plans, and (iv) a certificate signed by Tenant certifying that the amount of the such Requisition does not exceed the cost of the items, services and work covered thereby. Landlord shall have the right, upon reasonable advance notice to Tenant, to inspect Tenant’s books and records relating to each Requisition in order to verify the amount

thereof. Tenant shall submit Requisition(s) no more often than once every thirty (30) days.

Provided and on condition that, as of the date on which Tenant submits to Landlord any Requisition (together with all required supporting documentation) (i) Tenant has delivered Tenant’s Costs Certificate to Landlord, (ii) Tenant has submitted such Requisition to Landlord not later than the date that is Three Hundred Sixty-Five (365) days after the Second Additional Premises Rent Commencement Date, (iii) there exists no Event of Default, and (iv) there are no liens (unless bonded to the reasonable satisfaction of Landlord) against Tenant’s interest in the Lease or against the Building or the Site arising out of Tenant’s Work or any litigation in which Tenant is a party, then Landlord shall pay the Costs shown on such Requisition within thirty (30) days after Landlord’s receipt thereof; provided, however, that in no event shall Landlord have any obligation to pay or otherwise fund any amount in excess of the Tenant Allowance.

(F)    Notwithstanding anything to the contrary herein contained:

(i)    In addition to the other requirements applicable to Requisitions generally, as set forth in Section 3.1(E) above, it is understood and agreed that Landlord shall have no obligation to pay Tenant’s final Requisition, unless and until (a) Tenant has delivered to Landlord a final set of record drawings for Tenant’s Work, (b) Tenant has delivered to Landlord a certificate of substantial completion signed by Tenant’s architect, (c) Tenant has executed the Declaration Affixing the Commencement Date of the Second Additional Premises in the form annexed to this Second Amendment as Exhibit F and (d) a certificate of occupancy (which may be a temporary certificate of occupancy, provided that Tenant shall thereafter diligently satisfy all conditions to obtaining a permanent certificate of occupancy) in a timely manner has been approved for issuance by the applicable governmental authority respecting the Second Additional Premises.

(ii)    Landlord shall in no event be deemed, by undertaking to pay the Tenant Allowance or otherwise, to have assumed any obligations, in whole or in part, of Tenant to any design professionals, consultants, contractors, vendors, service providers, subcontractors, suppliers, workers, materialmen or other third parties.

(iii)    Except with respect to work and/or materials previously paid for by Tenant, as evidenced by paid invoices and written lien waivers provided to Landlord, Landlord shall have the right (but not the obligation) to have portions of the Tenant

Allowance paid to directly to Tenant’s design professionals, consultants, contractors, service providers, subcontractors or suppliers.

(iv)    In the event that Costs are less than the Tenant Allowance, Tenant shall not be entitled to any payment or credit, nor shall there be any application of the same toward Annual Fixed Rent or Additional Rent owed by Tenant under the Lease.”

8.    Section 9.26 of the Lease (as amended by Section 9 of the First Amendment) is hereby deleted in its entirety and replaced with the following:

“9.26    Right of First Offer

(A)    Subject to the provisions of this Section 9.26, and subject to (i) any and

all rights of tenants in the Office Park to lease the Expansion Space (as hereinafter defined) pursuant to the express expansion or extension rights in their respective leases and (ii) Landlord’s right to renew or extend the lease of an existing tenant in the Expansion Space (whether or not they have renewal or extension options in their respective leases), and provided that (x) no Event of Default has occurred and remains uncured under the Lease, (y) Tenant has not assigned the Lease or sublet more than 33% of the Premises, except as permitted under Section 5.6.4, and (z) the Lease is still in force and effect, Landlord agrees that during the Term, upon the occurrence of the Expansion Notice Trigger Date (as hereinafter defined), Landlord will give written notice to Tenant offering to lease the Expansion Space to Tenant pursuant to this Section 9.26 (“Landlord’s ROFO Notice”). Landlord’s ROFO Notice shall specify the estimated delivery date of the Expansion Space, the Annual Fixed Rent, Base Operating Expenses and Base Taxes for the Expansion Space, and any work allowance, free rent period or other material business terms upon which Landlord is willing to lease the Expansion Space.

(B)    If Tenant wishes to exercise Tenant’s right of first offer, Tenant shall have the right to do so by delivering notice to Landlord of Tenant’s desire to lease the entire space described in Landlord’s ROFO Notice (it being agreed that Tenant has no right to lease less than such entire space) (the “Tenant’s Acceptance Notice”), provided Landlord receives Tenant’s Acceptance Notice not later than that date which is ten (10) days after the date of Tenant’s receipt of Landlord’s ROFO Notice, time being of the essence. If Tenant shall deliver a timely Tenant’s Acceptance Notice, then the Lease shall automatically be deemed amended to incorporate the Expansion Space into the Premises on such terms and conditions, without the necessity for the execution of any additional documents; provided, however, Landlord and Tenant agree within fifteen (15) days of Landlord’s receipt of Tenant’s Acceptance Notice (or fifteen (15) days from the Broker Determination of Annual Fixed Rent, if Tenant requests the same pursuant to the terms hereof) to execute and deliver an amendment to the Lease prepared by Landlord and reasonably approved by Tenant incorporating the Expansion Space into the Premises upon all of the same terms and conditions in the Lease, except that: (i) the Annual Fixed Rent, which shall be as set forth in Landlord’s ROFO Notice or as otherwise agreed by the parties during the Negotiation Period (or as determined by Broker Determination, if so requested by Tenant pursuant to the terms hereof) shall be applicable to the Expansion Space; (ii) all other terms and conditions set forth in Landlord’s ROFO Notice shall be applicable to the Expansion Space; (iii) the lease term as to the Expansion Space shall be

coterminous with the Term (as it may be extended pursuant to Section 2 of this Second Amendment, or as it may be earlier terminated under the Lease); and (iv) those provisions of the Lease which conflict with the specific terms set forth in Landlord’s ROFO Notice shall not be applicable to the Expansion Space. If for any reason Tenant shall not so exercise such right within such period, time being of the essence with respect to such exercise, Landlord shall be free to lease the Expansion Space to a third party.

(C)    In the event Tenant desires to exercise its right of first offer, but Tenant disagrees with Landlord’s determination of the Annual Fixed Rent for the Expansion Space, Tenant shall provide Landlord with Tenant’s Acceptance Notice, meeting the requirements set forth above within the time period specified above, but Tenant’s Acceptance Notice shall also indicate that Tenant so disagrees, whereupon the parties shall negotiate in good faith for a period of fifteen (15) days (the “Negotiation Period”) from the date upon which Landlord receives Tenant’s Acceptance Notice to agree upon the Annual Fixed Rent. If the parties do not so agree within the Negotiation Period, then

Tenant shall have the right, by written notice given to Landlord within ten (10) days after the expiration of the Negotiation Period, to submit the Annual Fixed Rent for the Expansion Space to a Broker Determination of the Prevailing Market Rent (as defined in Exhibit B), which Broker Determination shall be made in the manner set forth in Exhibit B. In any event, Tenant’s delivery of Tenant’s Acceptance Notice shall be deemed to be the irrevocable exercise by Tenant of its right of first offer subject to and in accordance with the provisions of this Section 9.26.

(D)    If Landlord determines that possession of the Expansion Space will not be available for delivery to Tenant until on or after that date which is twelve (12) months prior to the end of the Second Extended Term, then: (i) if Tenant has no further right to extend the Term of the Lease (i.e. because Tenant's right to extend the Term of the Lease pursuant to Section 2 above and Section 9.18 of the Lease has been irrevocably waived by Tenant or has lapsed unexercised), then Landlord shall not be obligated to offer the Expansion Space for lease to Tenant, or to deliver a Landlord’s ROFO Notice to Tenant with respect thereto, nor shall Tenant have a right to lease the Expansion Space under the terms set forth herein or otherwise, or to receive a Landlord’s ROFO Notice with respect thereto, and (ii) if Tenant then has a right to extend the Term of the Lease pursuant to Section 2 above and Section 9.18 of the Lease which has not either lapsed unexercised or been irrevocably waived, then Landlord shall deliver a Landlord’s ROFO Notice to Tenant with respect thereto, but Tenant shall have no right to lease such Expansion Space unless, prior to, or simultaneously with, the giving of Tenant's Acceptance Notice, Tenant exercises such extension option, which option may be exercised without regard to any time periods for such exercise set forth in Section 2 above and Section 9.18 of the Lease so long as it is sent in accordance with the timing requirements set forth in this Section 9.26.(D)(ii). Notwithstanding Tenant's exercise of its extension option in accordance with the foregoing, the Annual Fixed Rent for the original Premises for such Extended Term shall be determined at the same time and in the same manner such Annual Fixed Rent would have been determined if Tenant had exercised the extension option within the time periods for such exercise set forth in Section 2 above and Section 9.18 of the Lease.

(E)    As used in this Section 9.26, the following terms shall have the meanings set forth below:

(i)    “Expansion Space” shall be approximately 16,564 square feet of rentable floor area on the first (1^st) floor of the Building, as shown on Exhibit G attached hereto and made a part hereof.

(ii)    “Expansion Notice Trigger Date” shall mean the date on which Landlord reaches a stage in negotiations with a third party to lease the Expansion Space that Landlord reasonably believes in good faith could result in the execution of a letter of intent to lease such space with such third party within fourteen (14) days.”

9.    Landlord acknowledges that Tenant shall have the right to increase the existing generator serving the Premises, including expanding the slab therefor, subject to and in accordance with the terms of the Lease, including, without limitation, Section 5.12 thereof.

10.    Section 2(A)(ii) of the Second Amendment is hereby deleted in its entirety and the following is inserted in place thereof:

“(ii)    The termination date in respect of the Temporary Premises (“Temporary

Premises Termination Date”) shall be the date that is the earlier to occur of (i) five (5) days after the Second Additional Premises Rent Commencement Date and (ii) the date that is seven (7) months after the Second Additional Premises Commencement Date.”

11.    Section 9.19 of the Lease (as amended by Section 10 of the First Amendment) is hereby deleted in its entirety and replaced with the following:

“9.19    Security Deposit.

(A)    (i)    The parties hereby acknowledge and agree that Landlord is currently holding a security deposit in the amount of Four Hundred Thousand and 00/100 Dollars ($400,000.00) (the “Existing Security Deposit”) in the form of an irrevocable letter of credit issued by Bank of America, N.A. (the “Letter of Credit”). In consideration of Landlord’s agreement to extend the Term of the Lease and to lease the Second Additional Premises to Tenant, Tenant shall deliver to Landlord, within thirty (30) days of the Effective Date, an additional security deposit in the amount of One Hundred Ninety-Five Thousand Four Hundred Thirty-Four and 00/100 Dollars ($195,434.00) (the “Additional Security Deposit” and collectively with the Existing Security Deposit, the “Security Deposit”) such that the total security deposit held by Landlord under the Lease shall be Five Hundred Ninety-Five Thousand Four Hundred Thirty-Four and 00/100 Dollars ($595,434.00). Such Additional Security Deposit shall be either in the form of an additional irrevocable, unconditional, negotiable letter of credit meeting the requirements of this Section 9.19, or an amendment to the existing Letter of Credit increasing the face amount thereof to Five Hundred Ninety-Five Thousand Four Hundred Thirty-Four and 00/100 Dollars ($595,434.00).

(ii)    Tenant agrees that Landlord shall hold the Security Deposit, throughout the Term of the Lease (including any extension thereof), as security for the performance by Tenant of all obligations on the part of Tenant to be kept and performed. Landlord shall have the right from time to time without prejudice to any other remedy Landlord may have on account thereof, to apply such deposit, or any part thereof, to Landlord’s damages arising from any Event of Default. If Landlord so applies all or any portion of

such deposit, Tenant shall within seven (7) days after notice from Landlord deliver cash to Landlord in an amount sufficient to restore such deposit to the full amount stated in this Section 9.19. While Landlord holds such deposit, Landlord shall have no obligation to pay interest on the same and shall have the right to commingle the same with Landlord’s other funds. If Landlord conveys Landlord’s interest under the Lease, the deposit, or any part thereof not previously applied, may be turned over by Landlord to Landlord’s grantee, and, if so turned over, Tenant agrees to look solely to such grantee for proper application of the deposit in accordance with the terms of this Section 9.19, and the return thereof in accordance herewith.

(iii)    Tenant shall have the right to provide such security deposit in one or two letters of credit, as described in Section 9.19(A)(i), and in the form of irrevocable, unconditional, negotiable letters of credit (each, a “Letter of Credit”). Each Letter of Credit shall (i) be issued by and drawn on a bank reasonably approved by Landlord and at a minimum having a long term issuer credit rating from Standard and Poor’s Professional Rating Service of A or a comparable rating from Moody’s Professional Rating Service, (ii) be substantially in the form attached hereto as Exhibit H, (iii) permit one or more draws thereunder to be made accompanied only by certification by Landlord or Landlord’s managing agent that pursuant to the terms of the Lease, Landlord is entitled to

draw upon such Letter of Credit, (iv) permit transfers at any time without charge, and (v) provide that any notices to Landlord be sent to the notice address provided for Landlord in the Lease. If the credit rating for the issuer of a Letter of Credit falls below the standard set forth in (i) above or if the financial condition of an issuer changes in any other material adverse way, Landlord shall have the right to require that Tenant provide a substitute letter of credit that complies in all respects with the requirements of this Section, and Tenant’s failure to provide the same within thirty (30) days following Landlord’s written demand therefor shall entitle Landlord to immediately draw upon the subject Letter of Credit. Any such Letter of Credit shall be for a term of two (2) years (or for one (1) year if the issuer thereof regularly and customarily only issues letters of credit for a maximum term of one (1) year) and shall in either case provide for automatic renewals through the date which is ninety (90) days subsequent to the scheduled expiration of the Lease (as the same may be extended) or if the issuer will not grant automatic renewals, each Letter of Credit shall be renewed by Tenant each year and each such renewal shall be delivered to and received by Landlord not later than sixty (60) days before the expiration of the then current Letter of Credit (herein called a “Renewal Presentation Date”). In the event of a failure to so deliver any such renewal Letter of Credit on or before the applicable Renewal Presentation Date, Landlord shall be entitled to present the then existing Letter of Credit for payment and to receive the proceeds thereof, which proceeds shall be held as Tenant’s security deposit, subject to the terms of this Section 9.19. Any failure or refusal to honor the Letter of Credit shall be at Tenant’s sole risk and shall not relieve Tenant of its obligation hereunder with regard to the security deposit. Upon the receipt by Landlord of one or more Letters of Credit meeting the requirements set forth herein, Landlord shall return to Tenant any cash security deposit then being held by Landlord, and thereafter each Letter of Credit shall be held by Landlord in accordance with the terms and conditions of this Section 9.19 as security for Tenant’s obligations hereunder.

(B)    (i)    Landlord shall return a One Hundred Thousand and 00/100 Dollar ($100,000.00) portion of such deposit to Tenant so that the remainder of such deposit

shall be Four Hundred Ninety-Five Thousand Four Hundred Thirty-Four and 00/100 Dollars ($495,434.00) (or if such deposit is in the form of a Letter of Credit, Landlord shall either exchange the Letter of Credit for a Letter of Credit delivered by Tenant or accept an amendment to such Letter of Credit, in either case which reduces the amount secured by the Letter of Credit by $100,000.00) on September 19, 2016; provided that (i) no Event of Default has occurred under the Lease and remains uncured as of September 19, 2016, and (ii) Landlord has not applied the Security Deposit, or any portion thereof, to Landlord's damages arising from any Event of Default, whether or not Tenant has restored the amount so applied by Landlord.

(ii)    Landlord shall return a Sixty-Five Thousand One Hundred Forty-Five and 00/100 Dollar ($65,145.00) portion of such deposit to Tenant so that the remainder of such deposit shall be Four Hundred Thirty Thousand Two Hundred Eighty-Nine and 00/100 Dollars ($430,289.00) (or if such deposit is in the form of a Letter of Credit, Landlord shall either exchange the Letter of Credit for a Letter of Credit delivered by Tenant or accept an amendment to such Letter of Credit, in either case which reduces the amount secured by the Letter of Credit by $65,145.00 and otherwise in strict conformity with the requirements herein) on the first (1^st) anniversary of the Second Additional Premises Rent Commencement Date; provided that (i) no Event of Default has occurred under this Lease and remains uncured as of such first (1^st) anniversary, and (ii) Landlord has not applied the Security Deposit, or any portion thereof, to Landlord's damages

arising from any Event of Default, whether or not Tenant has restored the amount so applied by Landlord.

(iii)    If Tenant believes that it has satisfied all the conditions precedent to a reduction in the amount of the Security Deposit, then it shall request such reduction in writing to Landlord, which request shall certify to Landlord that all such conditions have been satisfied. If Landlord determines that all of the aforesaid conditions are met, the Security Deposit shall be so reduced in accordance with this Section 9.19. No Letter of Credit shall automatically reduce, but any reduction in the amount thereof shall require Landlord’s prior written notice to the issuer of the applicable Letter of Credit of the reduced amount. Promptly after Landlord’s receipt of Tenant’s request for a reduction as described above, Landlord shall determine whether such a reduction is permitted in accordance with this Section 9.19, and if it is, Landlord shall notify the issuer of the applicable Letter of Credit of the amount to which the Letter of Credit shall be reduced.

(iv)    Tenant not then being in default and having performed all of its obligations under the Lease, including the payment of all Annual Fixed Rent, Landlord shall return the deposit, or so much thereof as shall not have theretofore been applied in accordance with the terms of this Section 9.19, to Tenant on the expiration or earlier termination of the term of the Lease (as the same may have been extended) and surrender possession of the Premises by Tenant to Landlord in the condition required in the Lease at such time.

(v)    Neither the holder of any mortgage nor the lessor in any ground lease on property which includes the Premises shall ever be responsible to Tenant for the return or application of any such deposit, whether or not it succeeds to the position of Landlord hereunder, unless such deposit shall have been received in hand by such holder or ground lessor.”

12.    (A)    Tenant warrants and represents that Tenant has not dealt with any broker in connection with the consummation of this Third Amendment except Colliers International (the “Broker”) and in the event any claim is made against Landlord relative to dealings by Tenant with any brokers other than the Broker, Tenant shall defend the claim against Landlord with counsel of Tenant’s selection first approved by Landlord (which approval will not be unreasonably withheld) and save harmless and indemnify Landlord on account of loss, cost or damage which may arise by reason of such claim.

(B)    Landlord warrants and represents that Landlord has not dealt with any broker in connection with the consummation of this Third Amendment, other than the Broker, and in the event any claim is made against Tenant relative to dealings by Landlord with brokers, Landlord shall defend the claim against Tenant with counsel of Landlord’s selection first approved by Tenant (which approval will not be unreasonably withheld) and save harmless and indemnify Tenant on account of loss, cost or damage which may arise by reason of such claim. Landlord agrees that it shall be solely responsible for the payment of brokerage commissions to the Broker, for the Second Extended Term as further outlined in a separate agreement between Landlord and the Broker.

13.    Except as otherwise expressly provided herein, all capitalized terms used herein without definition shall have the same meanings as are set forth in the Lease.

14.    Except as herein amended the Lease shall remain unchanged and in full force and effect. All references to the “Lease” shall be deemed to be references to the Lease as amended by the First Amendment, the Second Amendment and as herein amended.

15.    Each of Landlord and Tenant hereby represents and warrants to the other that all necessary action has been taken to enter this Third Amendment and that the person signing this Third Amendment on its behalf has been duly authorized to do so.

16.    The parties acknowledge and agree that this Second Amendment may be executed by electronic signature, which shall be considered as an original signature for all purposes and shall have the same force and effect as an original signature. Without limitation, “electronic signature” shall include faxed versions of an original signature or electronically scanned and transmitted versions (e.g., via pdf) of an original signature.

EXECUTED as of the date and year first above written.

6.Right of First Offer. Section 9.26 of the Lease (as previously amended) is hereby deleted in its entirety and replaced with the following:

“9.26 Right of First Offer

(A)    Subject to the provisions of this Section 9.26 (including, without limitation, Landlord’s rights under Section 9.26(E)(i) with respect to ROFO Space A (as hereinafter defined) and ROFO Space B (as hereinafter defined)), and subject to (i) any and all rights of tenants in the Office Park to lease the Potential ROFO Space (as hereinafter defined) pursuant to the express rights of first offer, first refusal, expansion, renewal or extension rights in their respective leases granted prior to the Seventh Amendment Effective Date that encumber what would otherwise have been Available Space (as hereinafter defined), and (ii)

Landlord’s right to renew or extend the lease of any then existing tenant in what would

(B)    If Tenant wishes to exercise Tenant’s right of first offer, Tenant shall have the right to do so by delivering notice to Landlord of Tenant’s desire to lease the entire Available Space described in Landlord’s ROFO Notice (it being agreed that Tenant has no right to lease less than such entire Available Space) (the “Tenant’s Acceptance Notice”), provided Landlord receives Tenant’s Acceptance Notice not later than that date which is fifteen (15) business days after the date of Tenant’s receipt of Landlord’s ROFO Notice, time being of the essence. If Tenant shall deliver a timely Tenant’s Acceptance Notice, then the Lease shall automatically be deemed amended to incorporate such Available Space into the Premises on such terms and conditions, without the necessity for the execution of any additional documents; provided, however, Landlord and Tenant agree within thirty (30) days of Landlord’s receipt of Tenant’s Acceptance Notice (or thirty (30) days from the determination of the Annual Fixed Rent for the Available Space pursuant to Section 9.26(C) below, if applicable) to execute and deliver an amendment to the Lease prepared by Landlord and reasonably approved by Tenant incorporating the Available Space into the Premises upon all of the same terms and conditions in the Lease, except that: (i) the Annual Fixed Rent, which shall be as set forth in Landlord’s ROFO Notice (or as determined pursuant to Section 9.26(C) below, if applicable) shall be applicable to the Available Space; (ii) all other terms and conditions set forth in Landlord’s ROFO Notice shall be applicable to the Available Space; (iii) the lease term as to the Available Space shall be coterminous with the Term (as it may be earlier terminated under the Lease); and (iv) those provisions of the Lease which conflict with the specific terms set forth in Landlord’s ROFO Notice shall not be applicable to the Available Space. If for any reason Tenant shall not so exercise such right within such fifteen (15) business day

(C)    In the event Tenant desires to exercise its right of first offer, but Tenant disagrees with Landlord’s determination of the Annual Fixed Rent for the Available Space, Tenant shall provide Landlord with Tenant’s Acceptance Notice, meeting the requirements set forth above within the time period specified above, but Tenant’s Acceptance Notice shall also indicate that Tenant so disagrees, whereupon the parties shall negotiate in good faith for a period of fifteen (15) business days (the “Negotiation Period”) from the date upon which Landlord receives Tenant’s Acceptance Notice to agree upon the Annual Fixed Rent. If the parties do not so agree within the Negotiation Period, then Tenant shall have the right, by written notice given to Landlord within fifteen (15) business days after the expiration of the Negotiation Period, to submit the Annual Fixed Rent for the Available Space to a Broker Determination of the Prevailing Market Rent (as defined in Exhibit B attached to the Third Amendment) for the Available Space, which Broker Determination shall be made in the manner set forth in Exhibit B attached to the Third Amendment and incorporated herein by reference. In any event, Tenant’s delivery of Tenant’s Acceptance Notice shall be deemed to be the irrevocable exercise by Tenant of its right of first offer subject to and in accordance with the provisions of this Section 9.26. If Tenant fails to timely initiate the Broker Determination of the Prevailing Market Rent pursuant to such Exhibit B within such additional fifteen (15) business day period, Landlord’s determination of the Prevailing Market Rent set forth in the Landlord’s ROFO Notice shall be binding on the parties.

(E)    As used in this Section 9.26, the following terms shall have the meanings set forth below:

(i)    “Potential ROFO Space” shall mean all or any portion of the space on the fourth (4th) floor South Wing of the Building or on the first (1st) floor South Wing of the Building and shown as “ROFO Premises” on Exhibit A attached to the Seventh Amendment and incorporated herein by reference; provided, however, that it is acknowledged and agreed that (x) “ROFO Space A” as shown on Exhibit A is vacant as of the date hereof, and Landlord shall have the right to initially lease such ROFO Space A (or any portion thereof) to any third party (or parties) as Landlord deems appropriate in its sole discretion, prior to triggering Tenant’s right of first offer under this Section 9.26 with respect to such ROFO Space A, and (y) “ROFO Space B” as shown on Exhibit A is available for reletting as of the date hereof, and Landlord shall have the right to initially release such ROFO Space B (or any portion thereof) to any third party (or parties) as Landlord deems appropriate in its sole discretion, prior to triggering Tenant’s right of first offer under this Section 9.26 with respect to such ROFO Space B.
