To the extent such costs and expenses payable by Tenant cannot be charged directly to, and paid by, Tenant, such costs and expenses shall be paid by Landlord but reimbursed by Tenant as Additional Rent.

Landlord and Tenant each acknowledges and agrees that the independent nature of the obligations of Tenant hereunder represents fair, reasonable and accepted commercial practice with respect to the type of property subject to this Lease, and that this agreement is the product of free and informed negotiation during which both Landlord and Tenant were represented by counsel skilled in negotiating and drafting commercial leases in Massachusetts, and that the acknowledgements and agreements contained herein are made with full knowledge of the holding in Wesson v. Leone Enterprises, Inc., 437 Mass. 708 (2002). Such acknowledgements, agreements and waivers by Tenant are a material inducement to Landlord entering into this Lease.

In all Landlord’s Statements rendered under this Section 2.8, amounts for periods partially within and partially without the accounting periods shall be appropriately apportioned, any items which are not determinable at the time of a Landlord’s Statement shall be included therein on the basis of Landlord’s estimate, and with respect thereto Landlord shall render promptly after determination of a supplemental Landlord’s Statement, and appropriate adjustment shall be made according thereto.

The entire Tenant’s Work shall be performed in a good and workmanlike manner and in compliance with all applicable laws, and Tenant and Tenant’s architects, engineers, consultants, general contractor and subcontractors shall perform such Tenant’s Work in compliance with all reasonable rules and regulations adopted by Landlord from time to time. The Tenant’s 18 Crosby Work and the Tenant’s 14 Crosby Work, as applicable, shall each be deemed to be “Substantially Complete” with respect to the 18 Crosby Premises or the 14 Crosby Premises, as applicable, on the date that all of the Tenant’s 18 Crosby Work or the Tenant’s 14 Crosby Work, as applicable, has been performed, other than any details of construction, mechanical adjustment or any other similar matter, the non-completion of which does not materially interfere with Tenant’s use of the 18 Crosby Premises or the 14 Crosby Premises, as applicable, and which can be completed or remedied after Tenant takes possession of the 18 Crosby Premises or the 14 Crosby Premises, as applicable, without causing material interference to Tenant’s use and occupancy of the 18 Crosby Premises or the 14 Crosby Premises, as applicable. Tenant shall obtain a certificate of occupancy with respect to the 18 Crosby Premises and the 14 Crosby Premises, as applicable, as issued by the applicable governing authority, and shall deliver such certificate of occupancy with respect to the 18 Crosby Premises and the 14 Crosby Premises, as applicable, to Landlord once received.

Landlord’s consent to the Tenant’s Work and Landlord’s approval of any such plans shall be without liability to or recourse against Landlord, shall not release Tenant from its obligations to comply strictly with the provisions of this Lease, and shall not constitute any representation or warranty by Landlord regarding the adequacy for any purpose of the Tenant’s Work or any such plans or their compliance with applicable law, and shall not relieve Tenant from obtaining Landlord’s express written approval to revisions thereto. Promptly after Substantial Completion of the Tenant’s 18 Crosby Work and the Tenant’s 14 Crosby Work, as applicable, with respect to the 18 Crosby Premises or the 14 Crosby Premises, as applicable, Tenant shall, at Tenant’s expense, obtain and deliver to Landlord copies of all sign-offs, letters of completion, approvals and certificates of any government authority required upon the completion of the Tenant’s 18 Crosby Work and the Tenant’s 14 Crosby Work, as applicable (including any required amendments to the certificate of occupancy for the 18 Crosby Premises, 14 Crosby Premises, 18 Crosby Building and/or the 14 Crosby Building) and “as-built” plans and specifications for the Tenant’s Work prepared as reasonably required by Landlord.

Any such contractor shall issue two (2) invoices, one with respect to Tenant’s share of such invoice, and one with respect to Landlord’s share of such invoice.

(m)               Payment of 14 Crosby TI Allowance. Provided Tenant has delivered to Landlord documentation detailing the applicable costs, including, without limitation, invoices, bills statements for the work completed or services rendered, and the materials and supplies used, and such other documentation as reasonably requested by Landlord, then Landlord shall make payment directly to Tenant within a commercially reasonable time period after Landlord’s receipt of such written request by Tenant and Landlord’s receipt of such documentation that portion of the 14 Crosby TI Allowance as outlined therein; provided, however, that if the total or estimated cost for the performance of the Tenant’s 14 Crosby Work will likely exceed the 14 Crosby TI Allowance, as reasonably determined by Landlord and Tenant, then Landlord, within a commercially reasonable time period, shall make such payment to Tenant directly for any portion of the Tenant’s 14 Crosby Work cost actually paid by Tenant on a pro rata basis, calculated according to the 14 Crosby TI Allowance versus the total cost and full scope budget for performance of the Tenant’s 14 Crosby Work, which total cost and full scope budget shall be provided by Tenant to Landlord on or prior to the date of execution of this Lease. Any such contractor shall issue two (2) invoices, one with respect to Tenant’s share of such invoice, and one with respect to Landlord’s share of such invoice.

(n)                Additional TIA. Within six (6) months following the execution of this Lease, Tenant may send Landlord a written request for up to an additional $40/RSF of the 18 Crosby Premises (i.e., an additional $2,120,000.00) (the “Additional TIA”), which Additional TIA must be used by Tenant in connection with the Tenant’s 18 Crosby Work. In the event that Tenant timely requests such Additional TIA, then (i) effective upon such timely request, the Base Rent with respect to the 18 Crosby Premises shall be increased by the amount necessary to fully amortize the Additional TIA in equal monthly payments with interest at a rate of eight percent (8%) per annum over the period from such request to the scheduled expiration date with respect to the 18 Crosby Premises, and (ii) Landlord and Tenant shall promptly execute a written instrument confirming the increased Base Rent with respect to the 18 Crosby Premises as a result hereunder in order to confirm the same.

In addition, Tenant shall, at its sole cost and expense, promptly comply with any Laws that relate to the “Base Building” (defined below), but only to the extent such obligations are triggered by Tenant’s use of the Premises, other than for the Permitted Use, as applicable, or alterations or improvements in the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, performed or requested by Tenant. “Base Building” shall include the structural portions of the 18 Crosby Building and/or the 14 Crosby Building, as applicable, the public restrooms and the 18 Crosby Building and/or the 14 Crosby Building, as applicable, mechanical, electrical and plumbing systems and equipment located in the internal core of the 18 Crosby Building and/or the 14 Crosby Building, as applicable, on the floor or floors on which the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, are located. Tenant shall promptly provide Landlord with copies of any notices it receives regarding an alleged violation of Law. Tenant shall not exceed the standard density limit for the 18 Crosby Building and/or the 14 Crosby Building, as applicable. Tenant shall comply with the rules and regulations of the Building attached as Exhibit F and such other reasonable rules and regulations adopted by Landlord from time to time, including rules and regulations for the performance of alterations and the rules and regulations for the Office Park.

5.4.          Obstructions; Items Visible From Exterior; Rules and Regulations: Not to obstruct in any manner any portion of the Building not hereby leased or any portion thereof or of the Lot used by Tenant in common with others; not, without written prior consent of Landlord which consent may be withheld or delayed for any reason, or for no reason, to permit the painting or placing of any signs on doors or any signs, curtains, blinds, shades, awnings, aerials or flagpoles, or the like, visible from outside the Premises; and to comply with all reasonable Rules and Regulations now or hereafter made by Landlord, of which Tenant has been given notice, in all instances for the care and use of the Building, Office Park and Lot and their facilities and approaches, including without limitation the Rules and Regulations set forth in Exhibit F hereto; Landlord shall not be liable to Tenant for the failure of other occupants of the Building to conform to such Rules and Regulations.

5.5.          Safety Appliances; Licenses: To keep the entire Premises equipped with all safety appliances required by law or ordinance or any other regulation of any public authority because of any use made by Tenant other than normal office use, and to procure all licenses and permits so required because of such use other than normal office use and, if requested by Landlord, to do any work so reasonably required because of such use, it being understood that the foregoing provisions shall not be construed to broaden in any way Tenant’s Permitted Use.

5.6.          Assignment; Sublease: Except in connection with a Permitted Transfer (defined below), Tenant covenants and agrees that it shall not assign, mortgage, pledge, hypothecate or otherwise transfer this Lease and/or Tenant’s interest in this Lease or sublet (which term, without limitation, shall include granting of concessions, licenses or the like) the whole or any part of the Premises (a “Proposed Transfer”) without Landlord’s prior written consent, not to be unreasonably withheld, subject to the following provisions. Without limitation, it is agreed that Landlord’s consent shall not be considered unreasonably withheld, conditioned or delayed if the proposed transferee is a governmental entity or an occupant of the Building or an occupant of any other buildings within the same project or the Office Park or if the proposed transferee, whether or not an occupant of the Building or an occupant of any other buildings within the same project or the Office Park, is in discussions with Landlord regarding the leasing of space within the Building or within any other buildings within the same project or the Office Park. Any assignment, mortgage, pledge, hypothecation, transfer or subletting not expressly permitted in or consented to by Landlord by a signed writing shall be void, ab initio, 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.

5.6.1.            Any request for Landlord’s consent hereunder shall be accompanied by such information regarding any proposed assignee, subtenant or occupant (the “Transferee”) as Landlord shall require. In the event Tenant desires to assign this Lease or sublet the whole or part of the Premises, Tenant shall give Landlord a notice (a “Proposed Transfer Notice”) of any Proposed Transfer, and said notice shall specify the provisions of the Proposed Transfer, including (a) the name and address of the proposed assignee or subtenant, (b) such information as to the proposed assignee’s or proposed subtenant’s net worth and financial capability and standing as may be required for Landlord to make a determination (provided, however, that Landlord shall hold such information confidential having the right to release same to its officers, accountants, attorneys and mortgage lenders on a confidential basis), (c) all the terms and provisions upon which the Proposed Transfer is to be made, including, without limitation, the proposed rent, and (d) such other information as may be required by Landlord to determine that such proposed assignment or subletting complies with the requirements of this Lease.

5.6.2.            Within thirty (30) days after receipt of the required information and documentation, Landlord shall either: (i) consent to the Proposed Transfer by execution of a consent agreement in a form designated by Landlord; (ii) refuse to consent to the Proposed Transfer in writing; or (iii) elect to recapture the portion of the Premises that Tenant is proposing to transfer or terminate the Lease if the entire Premises is being assigned or sublet by notifying Tenant of its election to recapture the Premises (“Landlord’s Recapture Notice”). If Landlord exercises its right to recapture (or terminate if the entire Premises is being assigned or sublet), (w) this Lease shall end and expire with respect to all or a portion of the Premises, as the case may be, on the date that such assignment or sublease was to commence, (x) Rent shall be apportioned, paid or refunded as of such date, (y) upon Landlord’s request, Tenant shall enter into an amendment of this Lease ratifying and confirming such total or partial termination, and setting forth any appropriate modifications to the terms and conditions of this Lease as a result thereof, and (z) Landlord may elect, in its discretion, to lease the Premises (or any part thereof) to Tenant’s prospective assignee or subtenant; provided, however, notwithstanding any provision contained herein to the contrary, Tenant shall have the right to rescind its request to sublet all or a portion of the Premises or assign its interest in the Lease by notifying Landlord, in writing, within ten (10) Business Days after Tenant’s receipt of Landlords’ Recapture Notice, and if Tenant timely rescinds said request to transfer, this Lease shall continue and full force and effect pursuant to the terms and conditions contained herein.

(a)                If Landlord shall consent in writing to the Proposed Transfer, as the case may be, then, in such event, Tenant may thereafter sublease or assign pursuant to Tenant’s Proposed Transfer Notice, as given hereunder; provided, however, that if such assignment or sublease shall not be executed and delivered to Landlord within thirty (30) days after the date of Landlord’s consent, the consent shall be deemed null and void. Tenant may (i) assign this Lease to a successor to Tenant by purchase, merger, consolidation or reorganization (an “Ownership Change”), or (ii) assign this Lease or sublet all or part of the 18 Crosby Premises or the 14 Crosby Premises, as applicable, to (A) an Affiliate or (B) subject to the terms and conditions contained herein, in connection with the sale, transfer, or other disposition of all or a substantial part of one or more of Tenant’s business units (a “Spin-Off Transfer”), without the consent of Landlord, provided that all of the following conditions are satisfied (each, a “Permitted Transfer”): (a) an Event of Default, or event which with the giving of notice or the passage of time, or both, would constitute an Event of Default, has not occurred during the term; (b) in the event of (y) an Ownership Change, Tenant’s successor shall own substantially all of the assets of Tenant and have a net worth which is at least equal to Tenant’s net worth as of the day prior to the proposed Ownership Change or (z) a Spin-Off Transfer, the proposed transferee has a net worth which is at least equal to Tenant’s net worth as of the day prior to the proposed Spin-Off Transfer multiplied by a ratio, the numerator of which is equal to the rentable square footage that the proposed transferee will occupy pursuant to the Spin-Off Transfer and the denominator of which is equal to the approximate rentable square footage of the entire Premises (i.e., approximately 85,770 rentable square feet) (the “Spin-Off Transfer Net Worth Requirement”); (c) the use is only for the Permitted Use, as applicable; (d) all amounts received by Tenant under such assignment or subletting qualify as “rents from real property” for purposes of Section 512(b)(3) and 856(d) of the Code, and (e) Tenant shall give Landlord written notice at least thirty (30) Business Days prior to the effective date of the Permitted Transfer. Tenant’s notice to Landlord shall include information and documentation evidencing the Permitted Transfer and showing that each of the above conditions has been satisfied. “Affiliate” shall mean an entity controlled by, controlling or under common control with Tenant (for such period of time as such entity continues to be controlled by, controlling or under common control with Tenant, it being agreed that the subsequent sale or transfer of stock resulting in a change in voting control, or any other transaction(s) having the overall effect that such entity ceases to be controlled by, controlling or under common control with Tenant, shall be treated as if such sale or transfer or transaction(s) were, for all purposes, an assignment of this Lease governed by the provisions of this Section). For the purposes of clarity, in the event that any such Spin-Off Transfer does not satisfy the Spin-Off Transfer Net Worth Requirement, then such Spin-Off Transfer shall not be considered a Permitted Transfer and shall be subject to Landlord’s prior written consent pursuant to the terms and conditions of this Section 5.6.

(b)                If for any assignment or sublease Tenant shall receive rent or other consideration either initially or over the term of the assignment or sublease, in excess of the Base Rent and Additional Rent called for with respect to the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, hereunder, Tenant shall pay to Landlord as Additional Rent, fifty percent (50%) of such excess of such payment of Rent or other consideration received by Tenant promptly after its receipt, after deduction of all reasonable costs and expenses incurred in connection with such assignment or sublease; provided, however, that Tenant shall provide Landlord with commercially reasonable documentation evidencing such costs.

(c)                Tenant shall not sublease the 18 Crosby Premises or the 14 Crosby Premises, as applicable, for an amount less than the lesser of (i) ninety-five percent (95%) of the Fair Market Rent, or (ii) Tenant’s Base Rent for the period during which the proposed sublease would take place, unless there is no vacant space in the 18 Crosby Building or the 14 Crosby Building, as applicable, or space coming available in the 18 Crosby Building or the 14 Crosby Building, as applicable, within one (1) year, capable of delivering premises comparable in size and quality to the portion of the 18 Crosby Premises or the 14 Crosby Premises, as applicable, proposed for sublease by the Tenant.

5.6.3.            It shall be a condition precedent to the validity of any assignment that both Tenant and the assignee enter into a separate written instrument directly with Landlord in a form and containing terms and provisions reasonably required by Landlord, including, without limitation, the agreement of the assignee to be bound directly to Landlord for all the obligations of the Tenant hereunder, including, without limitation, the obligation (a) to pay the rent and other amounts provided for under this Lease. Such assignment or subletting shall not relieve the Tenant named herein of any of the obligations of the Tenant hereunder. Furthermore, it shall be a condition precedent to the validity of any sublease that both Tenant and the sub-lessee enter into a separate written instrument directly with Landlord in a form and containing terms and provisions reasonably required by Landlord, including without limitation, the obligation of any sub-lessee to adhere to any and all rules, regulations or other non-monetary covenants of Tenant exclusive of Tenant’s rent obligations which may differ from those set forth in the sublease.

5.6.4.            As Additional Rent Tenant shall pay to Landlord as a fee for Landlord’s review of any proposed assignment or sublease requested by Tenant and the preparation of any associated documentation in connection therewith, within thirty (30) days after receipt of an invoice from Landlord, an amount equal to the sum of such reasonable out of pocket legal fees or other expenses incurred by Landlord in connection with such request, which amount shall not exceed Three Thousand and 00/100 Dollars ($3,000.00) per any such request.

5.6.5.            If this Lease be assigned, or if the Premises or any part thereof be sublet or occupied by anyone other than Tenant, without the aforesaid Landlord approval, Landlord may upon prior notice to Tenant, at any time and from time to time, collect rent and other charges from the assignee, sublessee or occupant 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 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.

5.6.6.            The consent by Landlord to a Proposed Transfer under any of the provisions hereof shall in no way be construed to relieve Tenant from obtaining the express consent in writing of Landlord to any further assignment or subletting.

5.6.7.            Intentionally Omitted.

5.6.8.            If this Lease terminates prior to the expiration date, then such sublease shall terminate and expire concurrent therewith; provided, however, if Landlord elects, in its sole and unfettered discretion, by express written notice to such Tenant or subsequent transferor, to recognize said sublease, then notwithstanding the termination of this Lease, the sublease shall remain in effect as a direct lease between Landlord and Tenant or subsequent transferor, and such Transferee shall attorn to Landlord pursuant to the then executory provisions of such sublease, except that Landlord shall not be (A) liable for any previous act or omission of Tenant under such sublease, (B) subject to any counterclaim, offset or defense which theretofore accrued to such Transferee against Tenant, (C) bound by any previous modification of such sublease not consented to by Landlord or by any prepayment of more than one month’s rent, (D) bound to return such Transferee’s security deposit, if any, except to the extent Landlord shall receive actual possession of such deposit and such Transferee shall be entitled to the return of all or any portion of such deposit under the terms of its sublease, or (E) obligated to make any payment to or on behalf of such Transferee, or to perform any alterations or improvements in the sublet space or the 18 Crosby Building and/or the 14 Crosbt Building, as applicable, or in any way to prepare the subleased space for occupancy, beyond Landlord’s obligations under this Lease. The provisions of this Section shall be self-operative, and no further instrument shall be required to give effect to this provision, provided that the Transferee shall execute and deliver to Landlord any instruments Landlord may reasonably request to evidence and confirm such subordination and attornment.

5.6.9.            Notwithstanding anything to the contrary contained in this Section 5.6, neither Tenant nor any other person having a right to possess, use, or occupy (for convenience, collectively referred to in this subsection as “Use”) the Premises shall enter into any lease, sublease, license, concession or other agreement for Use of all or any portion of the Premises which provides for rental or other payment for such Use based, in whole or in part, on the net income or profits derived by any person that leases, possesses, uses, or occupies all or any portion of the Premises (other than an amount based on a fixed percentage or percentages of receipts or sales), and any such purported lease, sublease, license, concession or other agreement shall be absolutely void and ineffective as a transfer of any right or interest in the Use of all or any part of the Premises.

5.7.          Insurance; Indemnification.

5.7.1.            Insurance. With respect to the 18 Crosby Premises and the 14 Crosby Premises, Tenant shall at its sole cost and expense take out and keep in force and effect during the term and any extensions thereof, the following insurance coverage:

(i) Commercial General Liability Insurance covering claims of bodily injury, personal injury and property damage arising out of Tenant’s operations, hired and non-owned automobile liability and liabilities assumed in an insured contract, including coverage formerly known as broad form, on an occurrence basis, with minimum primary limits of $5,000,000 each occurrence and $5,000,000 annual aggregate (and not more than $25,000 self-insured retention) or such other limits as Landlord may reasonably require and which can be satisfied through the use of primary and/or umbrella liability policies.

(ii) “Special Causes of Loss” Property insurance covering (i) all Tenant’s Property (as hereinafter defined), and (ii) any leasehold improvements installed by Tenant, whether pursuant to this Lease or pursuant to any prior lease or other agreement to which Tenant was a party (“Tenant-Insured Improvements”). Such insurance shall be written on a special cause of loss form for physical loss or damage, for the full replacement cost value (subject to reasonable deductible amounts) without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance, and shall include coverage for damage or other loss caused by fire or other peril, including vandalism and malicious mischief, theft, water damage of any type, including sprinkler leakage, bursting or stoppage of pipes, and explosion, and providing business interruption coverage for a period of one year.

(iii) Worker’s Compensation and Employer’s Liability or other similar insurance to the extent required by Law.

(iv) Cyber Liability Insurance in the amount of $1,000,000.

Form of Policies. The minimum limits of insurance required to be carried by Tenant shall not limit Tenant’s liability. Such insurance shall (i) be issued by an insurance company that has an A.M. Best rating of not less than A-VIII; (ii) be in form and content reasonably acceptable to Landlord; (iii) provide that it shall not be cancelled or materially changed without thirty (30) days’ prior notice to Landlord, except that ten (10) days’ prior notice may be given in the case of nonpayment of premiums; (iv) contain a waiver by the insurer of any rights of subrogation or indemnity or any other claim to which the insurer might otherwise be entitled against Landlord or the agents or employees of Landlord, and (v) contain a cross liability clause. Tenant’s Commercial General Liability Insurance shall (a) add Landlord, Landlord’s managing agent, and any other party designated by Landlord (“Additional Insured Parties”) as additional insureds under a Blanket Additional Insured Endorsement; and (b) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and non-contributing with Tenant’s insurance. Landlord shall be designated as a loss payee with respect to Tenant’s Property insurance on any Tenant-Insured Improvements. Tenant shall deliver to Landlord, on or before the 18 Crosby Commencement Date and the 14 Crosby Commencement Date, as applicable, and at least ten (10) days before the expiration dates thereof, certificates from Tenant’s insurance company on the forms currently designated “ACORD 28” (Evidence of Commercial Property Insurance) and “ACORD 25-S” (Certificate of Liability Insurance) or the equivalent. Attached to the ACORD 25-S (or equivalent) there shall be an endorsement specifically adding the names of the Additional Insured Parties as additional insureds which shall be binding on Tenant’s insurance company and shall expressly require the insurance company to notify each Additional Insured Party in writing at least thirty (30) days before any termination, except that ten (10) days’ prior notice may be given in the case of nonpayment of premiums. Upon Landlord’s request, Tenant shall deliver to Landlord, in lieu of such certificates, copies of the policies of insurance required to be carried under this Section showing that the Additional Insured Parties are included as additional insureds under the Blanket Additional Insured Endorsement.

Tenant shall maintain such increased amounts of the insurance required to be carried by Tenant under this Section, and such other types and amounts of insurance covering the 18 Crosby Premises and the 14 Crosby Premises, as applicable, and Tenant’s operations therein, as may be reasonably requested by Landlord, but not in excess of the amounts and types of insurance then being required by landlords of buildings comparable to and in the vicinity of the 18 Crosby Building and the 14 Crosby Building, as applicable.

Landlord makes no representation or warranty to Tenant that the amount of insurance required to be carried by Tenant under the terms of this Lease is adequate to fully protect Tenant’s interests. Tenant is encouraged to evaluate its insurance needs and obtain whatever additional types or amounts of insurance that it may deem desirable or appropriate.

5.7.2. Indemnification and Liability: To the maximum extent such agreement may be made effective according to law, Tenant shall defend, indemnify and save harmless, Landlord and its agents and employees (the “Landlord Indemnities”) against and from all liabilities, obligations, damages, penalties, claims, costs, charges and expenses, including reasonable architects’ and attorneys’ fees, which may be imposed upon or incurred by or asserted against Landlord, its employees and/or its agents by reason of any of the following occurring during the term, or during any period of time prior to the 18 Crosby Commencement Date and/or the 14 Crosby Commencement Date, as applicable, that Tenant may have been given access to or possession of all or any part of the Premises arising out of (i) any work, or thing being done in on or about the Premises or the Office Park or any part thereof by or at the instance of Tenant, its agents, contractors, subcontractors, servants, employees, licensees or invitees, excepting those actions which are a result of the negligence or willful misconduct of Landlord, its agents, contractors, servants or employees; (ii) any negligence or otherwise wrongful act or omission on the part of Tenant or any of its agents, contractors, subcontractors, servants, employees, subtenants, licensees or invitees; (iii) any accident, injury or damage to any person or property occurring in, on or about the Premises, the Office Park or any part thereof or the common area, if such injury in the common area is alleged or claimed to be due to any act or omission of Tenant, excepting those accidents, injuries or damages which result from the negligence or willful misconduct of Landlord, its agents, contractors, servants or employees; (iv) Tenant’s use of, or the existence of, any of Tenant’s video camera equipment or monitors on the Premises, Building or Lot; and (v) any failure on the part of Tenant to perform or comply with any of the covenants, agreements, terms, provisions, conditions or limitations contained in this Lease on its part to be performed or complied with. In case any action or proceeding is brought against Landlord by reason of any such claim, Tenant upon written notice from Landlord shall at Tenant’s expense resist or defend such action or proceeding by counsel reasonably acceptable to Landlord. In the event of failure by Tenant to fully perform such defense in accordance with this Section, Landlord, at its option, and without relieving Tenant of its obligations hereunder, may so perform such defense, but all costs and expenses so incurred by Landlord in that event shall be reimbursed by Tenant to Landlord, together with interest on the same from the date any such expense was paid by Landlord until reimbursed by Tenant, at the rate of interest contained in Section 2.9. Tenant further covenants and agrees to indemnify, defend and hold all Landlord Indemnitees harmless from any and all mechanic’s and materialmen’s liens and/or claims of any contractors, subcontractors or materialmen claiming by, through or under Tenant with respect to any work performed, or labor, materials or supplies provided, in connection with any work performed by or on behalf of Tenant, its employees, agents or contractors, on or with respect to Premises. This Section shall survive the expiration or termination of this Lease.

(a)                Except in the case of Landlord’s gross negligence or willful misconduct, Tenant hereby waives all claims against and releases Landlord and its trustees, managers, members, principals, beneficiaries, partners, officers, directors, employees, mortgagees and agents (the “Landlord Related Parties”) from all claims for any injury to or death of persons, damage to property or business loss in any manner related to (a) Force Majeure, (b) acts of third parties, (c) the bursting or leaking of any tank, water closet, drain or other pipe, (d) the inadequacy or failure of any security or protective services, personnel or equipment, or (e) any matter not within the reasonable control of Landlord.

5.8.          Tenant’s Risk: That all of the furnishings, fixtures, equipment, effects and property of every kind, nature and description of Tenant and of all persons claiming by, through or under Tenant which, during the continuance of this Lease or any occupancy of the Premises by Tenant or anyone claiming under Tenant may be on the Premises or elsewhere in the Building or on the Lot or in the Office Park, shall be at the sole risk and hazard of Tenant, except as provided below, and if the whole or any part thereof shall be destroyed or damaged by fire, water or otherwise, or by the leakage or bursting of water pipes, steam pipes, or other pipes, by theft or from any other cause, no part of said loss or damage is to be charged to or be borne by Landlord except and solely to the extent that such loss occurs due to the gross negligence of willful misconduct of the Landlord, its employees and/or agents, contractors, managers, principals, or members.

5.9.          Right of Entry: To permit Landlord and its agents: to examine the Premises (i) immediately in the event of an emergency or (ii) upon twenty-four (24) hour prior written notice for a non-emergency and, if Landlord shall so elect, to make any repairs or replacements Landlord may deem necessary; to remove, at Tenant’s expense, any alterations, additions, 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 twelve (12) months preceding expiration of the term and to prospective purchasers and mortgagees at all reasonable times upon reasonable notice. Entry by Landlord shall not constitute a constructive eviction or entitle Tenant to an abatement or reduction of Rent.

5.10.        Security: To comply with all such measures as Landlord may reasonably deem advisable for the security of the Building and the Office Park and its occupants, including, without limitation, the evacuation of the Building or Office Park for cause, suspected cause, or for drill purposes, the temporary denial of access to the Building or Office Park, and the closing of the Building or Office Park after regular working hours, (i.e. 8:00 a.m. to 6:00 p.m. on business week days and on Saturdays from 9:00 a.m. to 12:00 p.m.) Sundays and legal holidays (the “Building Service Hours”), subject, however, to Tenant’s right to admittance when the Building is closed after regular working hours by use of a secure card access system which is automatically activated outside of such regular working hours, or under such other regulations as Landlord may prescribe from time to time.

Landlord shall be the sole determinant of the type and amount of any access control or courtesy guard services to be provided to the Building and Office Park, if any. IN ALL EVENTS, LANDLORD SHALL NOT BE LIABLE TO TENANT, AND TENANT HEREBY WAIVES ANY CLAIM AGAINST LANDLORD, FOR (I) ANY UNAUTHORIZED OR CRIMINAL ENTRY OF THIRD PARTIES INTO THE PREMISES, THE OFFICE PARK OR THE BUILDING, OR (II) ANY DAMAGE TO PERSONS OR ANY LOSS OF PROPERTY IN AND ABOUT THE PREMISES, THE OFFICE PARK OR THE BUILDING, BY OR FROM ANY UNAUTHORIZED OR CRIMINAL ACTS OF THIRD PARTIES, REGARDLESS OF ANY ACTION, INACTION, FAILURE, BREAKDOWN, MALFUNCTION AND/OR INSUFFICIENCY OF THE ACCESS CONTROL OR COURTESY GUARD SERVICES PROVIDED BY LANDLORD.

Subject to the foregoing, Tenant may install, at its own expense, a security system for the Premises, provided, however, that (i) Tenant shall obtain Landlord’s prior written consent prior to such installation and (ii) Tenant shall provide Landlord with all means necessary to immediately enter the Premises 24 hours per day, 7 days per week.

5.11.        Personal Property Taxes: To pay promptly when due all taxes which may be imposed upon personal property installed by Tenant (including, without limitation, fixtures and equipment) in the Premises to whomever assessed.

5.12.        Payment of Litigation Expenses: As Additional Rent, to pay all reasonable costs, counsel and other fees incurred by Landlord in connection with the successful enforcement by Landlord of any obligations of Tenant under this Lease.

5.13.        Tenant Holdover: To upon the expiration or earlier termination of the term of this Lease, quit and surrender the entire Premises to Landlord in the condition described in this Lease. Any holding over by the Tenant after the expiration or earlier termination of the Term shall be treated as a tenancy at sufferance, at the Rent set forth below, and otherwise on the terms and conditions of this Lease. For the period of such unauthorized occupancy, Tenant shall pay to Landlord (a) one hundred fifty percent (150%) of the total of the Base Rent and Additional Rent with respect to the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, in effect during the last month of the Term of this Lease for the first three (3) months or portion thereof and (b) two hundred percent (200%) of the total of the Base Rent and Additional Rent with respect to the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, in effect during the last month of the Term of this Lease for any subsequent months in which Tenant shall retain possession of either the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, or any part thereof after the termination of this Lease, whether by lapse of time or otherwise. Tenant shall also pay all damages sustained by Landlord on account thereof; provided, however, that Tenant shall only be liable for consequential damages hereunder if (i) Tenant has held over in the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, for more than thirty (30) days, and (ii) Landlord has provided Tenant with thirty (30) days written notice that it will be expecting Tenant to be responsible for any such consequential damages in connection with such holdover. For the purposes of clarity, Tenant shall have no right to occupy all or any part of the Premises after the expiration or earlier termination of this Lease. The provisions of this subsection shall not operate as a waiver by Landlord on the right of re-entry provided in this Lease or by statute.

5.14.        Hazardous Wastes: Not to use any portion of the Premises, Office Park, Building or Lot for the use, generation, treatment, storage or disposal of “oil”, “hazardous material”, “hazardous waste”, or “hazardous substances” (collectively, the “Materials”), as such terms are defined under the Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C. S9601 et seq., as amended, the Resource Conservation and Recovery act of 1976, 42 U.S.C. S6901 et seq., as amended, and the regulations promulgated thereunder, and all applicable state and local laws, rules and regulations, including, without limitation, Massachusetts General Laws, Chapters 21C and 21E (the “Superfund and Hazardous Waste Laws”), or remove any Materials from the Office Park and/ or the Property without the express written prior consent of Landlord and, if required, its mortgagees, and then only to the extent that the presence or removal of the Materials is (i) properly licensed and approved by all appropriate governmental officials and in accordance with all applicable laws and regulations and (ii) in compliance with any terms and conditions stated in said prior written approvals by the Landlord or its mortgagees. Without limiting the generality of Tenant’s obligation to comply with Laws as otherwise provided in this Lease, Tenant shall, at its sole cost and expense, comply with all Laws in connection with this Section 5.14. Tenant shall obtain and maintain any and all necessary permits, licenses, certifications and approvals appropriate or required for the use, handling, storage, and disposal of any Materials used, stored, generated, transported, handled, blended, or recycled by Tenant on the Premises. Landlord shall have a continuing right, without obligation, to require Tenant to obtain, and to review and inspect any and all such permits, licenses, certifications and approvals, together with copies of any and all Materials management plans and programs, any and all Materials risk management and pollution prevention programs, and any and all Materials emergency response and employee training programs respecting Tenant’s use of Materials. Upon the reasonable request of Landlord, Tenant shall deliver to Landlord a narrative description explaining the nature and scope of Tenant’s activities involving Materials and showing to Landlord’s satisfaction compliance with all Laws and the terms of this Lease. As a material inducement to Landlord to enter into this Lease with Tenant, Tenant has fully and accurately completed Landlord’s Pre-Leasing Environmental Exposure Questionnaire (the “Environmental Questionnaire”), which is attached hereto as Exhibit H. Tenant shall promptly provide Landlord with copies of all notices received by it, including, without limitation, any notice of violations, notice of responsibility or demand for action from any federal state or local authority or official in connection with the presence of Materials in or about the Property and/or the Office park or removal of Materials from the Property and/or the Office Park. In the event of any release of Materials by Tenant, its employees, agents, contractors or invitees, as defined in the Superfund and Hazardous Laws, Tenant shall promptly remedy the problem in accordance with all applicable laws and requirements and shall indemnify and hold the Landlord harmless from and against all loss, costs, liability and damage, including attorneys’ fees and the cost of litigation, arising from the presence or release of any Materials by Tenant, its employees, agents, contractors or invitees, in or on the Premises or removal of Materials released by Tenant, its employees, agents, contractors or invitees, from the Property and/or the Office Park. In addition to the foregoing and notwithstanding anything to the contrary contained herein, if any written report prepared by a qualified environmental consultant, including any report containing results of any environmental assessment (an “Environmental Report”) shall indicate (i) the presence of any Materials as to which Tenant has a removal or remediation obligation under this Section, and (ii) that as a result of same, the investigation, characterization, monitoring, assessment, repair, closure, remediation, removal, or other clean-up (the “Clean-up”) of any Materials is required, Tenant shall immediately prepare and submit to Landlord within thirty (30) days after receipt of the Environmental Report a comprehensive plan, subject to Landlord’s written approval, specifying the actions to be taken by Tenant to perform the Clean-up so that the Premises are restored to the conditions required by this Lease. Upon Landlord’s approval of the Clean-up plan, Tenant shall, at Tenant’s sole cost and expense, without limitation of any rights and remedies of Landlord under this Lease, immediately implement such plan with a consultant reasonably acceptable to Landlord and proceed to Clean-up Materials in accordance with all applicable laws and as required by such plan and this Lease. If, within thirty (30) days after receiving a copy of such Environmental Report, Tenant fails either (a) to complete such Clean-up, or (b) with respect to any Clean-up that cannot be completed within such 30-day period, fails to proceed with diligence to prepare the Clean-up plan and complete the Clean-up as promptly as practicable, then Landlord shall have the right, but not the obligation, and without waiving any other rights under this Lease, to carry out any Clean-up recommended by the Environmental Report or required by any governmental authority having jurisdiction over the Premises, and recover all of the costs and expenses thereof from Tenant as Additional Rent, payable within ten (10) days after receipt of written demand therefor. Tenant shall continue to pay all Rent due or accruing under this Lease during any Clean-up, and shall not be entitled to any reduction, offset or deferral of any Base Rent or Additional Rent due or accruing under this Lease during any such Clean-up. Tenant shall complete any Clean-up prior to surrender of the entire Premises upon the expiration or earlier termination of this Lease, and shall fully comply with all Laws and requirements of any governmental authority with respect to such completion, including, without limitation, fully comply with any requirement to file a risk assessment, mitigation plan or other information with any such governmental authority in conjunction with the Clean-up prior to such surrender. Tenant shall obtain and deliver to Landlord a letter or other written determination from the overseeing governmental authority confirming that the Clean-up has been completed in accordance with all requirements of such governmental authority and that no further response action of any kind is required for the unrestricted use of the Premises (“Closure Letter”), but only to the extent that such Closure Letter is typically issued by the applicable governmental entity; provided, however, that if such applicable governmental entity does not typically issue such Closure Letter, then Tenant shall use commercially reasonable and diligent efforts to obtain and deliver to Landlord such Closure Letter. Upon the expiration or earlier termination of this Lease, Tenant shall also be obligated to close all permits obtained in connection with Materials in accordance with Laws. Should any Clean-up for which Tenant is responsible not be completed, or should Tenant not receive the Closure Letter, if applicable, and any governmental approvals required under Laws in conjunction with such Clean-up prior to the expiration or earlier termination of this Lease, and Tenant’s failure to receive the Closure Letter is prohibiting Landlord from leasing the Premises or any part thereof to a third party, or prevents the occupancy or use of the Premises or any part thereof by a third party, then Tenant shall be liable to Landlord as a holdover tenant until such prohibition or restrictions on Landlord reletting the Premises or prevention of the occupancy or use of the Premises or any part thereof by a third party are/is lifted. The foregoing shall not prohibit Tenant from possessing minimal and customary quantities of those cleaning materials used for the operation of Tenant’s equipment in the Premises. Tenant agrees to indemnify, defend and hold Landlord and each Landlord Indemnitee harmless for, from and against any and all claims, actions, administrative proceedings (including informal proceedings), judgments, damages, punitive damages, penalties, fines, costs, liabilities, interest or losses, including reasonable attorneys’ fees and expenses, court costs, consultant fees, and expert fees, together with all other costs and expenses of any kind or nature that arise during or after the Term indirectly arising out of or resulting from the presence, suspected presence, transportation, generation, disposal or release of any Materials at, on, about, from, under or within the Premises, or any portion thereof caused by Tenant or Tenant’s employees, agents, representatives, contractors or the like. Each of the covenants and agreements of Tenant set forth in this Section shall survive the expiration or earlier termination of this Lease.

Landlord represents and warrants to Tenant that, as of the date hereof, to Landlord’s actual knowledge, Landlord is not aware of any Materials which exist or are located on or in the Premises in violation of Superfund and Hazardous Waste Laws. Except as to any Materials introduced to or generated at the entire Premises by Tenant or Tenant’s employees, agents, invitees and the like in violation of any Laws, or as introduced or generated by Tenant in violation of the terms and conditions of this Lease, this Section will not be applicable to Tenant or Tenant’s employees, agents, invitees and the like with respect to, and neither Tenant nor Tenant’s employees, agents, invitees and the like will have any responsibility or liability whatsoever for, resulting from, or in any way related to: (a) any Materials at, in, on, under, emanating from or in connection with the entire Premises prior to Tenant’s occupation thereof; or (b) the negligent acts or the willful misconduct of Landlord.

Prior to the expiration of the Lease (or within thirty (30) days after any earlier termination), Tenant shall clean and otherwise decommission all interior surfaces (including floors, walls, ceilings, and counters), piping, supply lines, waste lines and plumbing in or serving the Premises, and all exhaust or other ductwork in or serving the Premises, in each case that has carried, released or otherwise been exposed to any Materials due to Tenant’s use or occupancy of the Premises, and shall otherwise clean the Premises so as to permit the Environmental Assessment called for by this Section to be issued. Prior to the expiration of this Lease (or within thirty (30) days after any earlier termination), Tenant, at Tenant’s expense, shall obtain for Landlord a report (an “Environmental Assessment”) addressed to Landlord (and, at Tenant’s election, Tenant) by a reputable licensed environmental engineer or industrial hygienist that is designated by Tenant and acceptable to Landlord in Landlord’s reasonable discretion, which report shall be based on the environmental engineer’s inspection of the Premises and shall state, to Landlord’s reasonable satisfaction, that (a) all Materials described herein, if any, existing prior to such decommissioning, have been removed in accordance with Laws; (b) all Materials described herein, if any, have been removed in accordance with Laws from the interior surfaces of the Premises (including floors, walls, ceilings, and counters), piping, supply lines, waste lines and plumbing, and all such exhaust or other ductwork in the Premises, may be reused by a subsequent tenant or disposed of in compliance with Laws without incurring special costs or undertaking special procedures for demolition, disposal, investigation, assessment, cleaning or removal of such Materials and without giving notice in connection with such Materials; and (c) the Premises may be reoccupied for office, research and development, and/or laboratory uses, as applicable, demolished or renovated without incurring special costs or undertaking special procedures for disposal, investigation, assessment, cleaning or removal of Materials described herein and without giving notice in connection with Materials. Further, for purposes of clauses (b) and (c), “special costs” or “special procedures” shall mean costs or procedures, as the case may be, that would not be incurred but for the nature of the Materials as Hazardous Materials instead of non-hazardous materials. The report shall also include reasonable detail concerning the clean-up measures taken, the clean-up locations, the tests run and the analytic results. Tenant shall submit to Landlord the identity of the applicable consultants and the scope of the proposed Environmental Assessment for Landlord’s reasonable review and approval at least thirty (30) days prior to commencing the work described therein or at least sixty (60) days prior to the expiration of the Term, whichever is earlier. If Tenant fails to perform its obligations under this Section, without limiting any other right or remedy, Landlord may, on five (5) Business Days’ prior written notice to Tenant perform such obligations at Tenant’s expense if Tenant has not commenced to do so within said five (5) Business Day period, and Tenant shall within ten (10) days of written demand reimburse Landlord for all reasonable out-of-pocket costs and expenses incurred by Landlord in connection with such work. Tenant’s obligations under this Section shall survive the expiration or earlier termination of this Lease. In addition, at Landlord’s election, Landlord may inspect the Premises and/or the Property for Materials at Landlord’s cost and expense within sixty (60) days of Tenant’s surrender of the Premises at the expiration or earlier termination of this Lease. Tenant shall pay for all such costs and expenses incurred by Landlord in connection with such inspection if such inspection reveals that a release or threat of release of Materials exists at the Property or Premises as a result of the acts or omissions of Tenant, its officers, employees, contractors, and agents.

5.15.        Tenant’s Financial Condition. During the term of this Lease, (i) within ninety (90) days following the end of each Tenant fiscal year and (ii) within ten (10) Business Days after request by Landlord, which request shall not be made more than once per calendar year, Tenant shall, upon the signing of a commercially reasonable confidentiality agreement between the parties, deliver to Landlord Tenant’s financial statements (which shall be for the latest available year). Landlord shall keep all such information confidential and shall require any third party to whom the Landlord is entitled hereunder to furnish the same to maintain such confidentiality. Such financial statements or credit information may be delivered to Landlord’s mortgagees and lenders and prospective mortgagees, lenders, and purchasers, provided that Landlord advises such parties of the confidentiality provisions of this Section. Tenant represents and warrants to Landlord that each such financial statement shall be true and accurate in all material respects as of the date of such statement.

ARTICLE VI.

CASUALTY AND EMINENT DOMAIN

6.1.          Casualty.

6.1.1.            Termination or Restoration by Landlord. Should 20% or greater of either of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, be materially damaged, or if either the 18 Crosby Building or the 14 Crosby Building, as applicable, of which either of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, are a part, be substantially damaged by fire or other casualty, Landlord may, at its sole discretion, elect to either (i) terminate this Lease with respect to either the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, or (ii) restore either of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, in accordance with the terms of this Section 6.1.

Unless Landlord or Tenant terminates this Lease as aforesaid or Landlord’s lender or mortgage holder requires otherwise, Landlord shall apply all insurance proceeds received by Landlord as the result of the casualty to restoration of either the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable. Notwithstanding anything to the contrary contained herein, in the event of a casualty in which Landlord’s lender or mortgage holder does not allow insurance proceeds to be so applied, Landlord shall have the option to terminate this Lease with respect to the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, and shall notify Tenant within ten (10) days thereof as to whether Landlord will fund the restoration or terminate the Lease.

6.1.3.            Abatement of Rent. If Landlord elects to restore either of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, all Rent shall abate, on a pro rata basis, in proportion to the portion of either of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, rendered unusable from the date of the damage or taking until the earlier of when repairs are substantially completed such that Tenant can use the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, for the Permitted Use, or the Term ends, provided, however, that if such damage or casualty was caused by Tenant, then Tenant’s Rent shall not abate.

If the whole or any material part of the Lot, the 18 Crosby Building and/or the 14 Crosby Building, as applicable, or either of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, shall be acquired or condemned for any public or quasi-public use or purpose, this Lease and the term shall end as of the date of the vesting of title with the same effect as if said date were the expiration date. Landlord shall also have the right to terminate this Lease with respect to the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, if there is a taking of any portion of the 18 Crosby Building and/or the 14 Crosby Building, as applicable, or Property which would have a material adverse effect on Landlord’s ability to profitably operate the remainder of the 18 Crosby Building and/or the 14 Crosby Building, as applicable. If only a part of the 18 Crosby Building and/or the 14 Crosby Building, as applicable, and not the entire 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, shall be so acquired or condemned then:

Except as hereinafter provided, this Lease and the term shall continue in force and effect, but, if a part of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, is included in the part of the Lot so acquired or condemned, from and after the date of the vesting of title, the Base Rent and the floor area of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, shall be reduced in the proportion which the area of the part of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, so acquired or condemned bears to the total area of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, immediately prior to such acquisition or condemnation and Tenant’s Proportionate Share shall be adjusted accordingly on a pro rata basis, according to the new rentable square footage of the 18 Crosby Building and/or the 14 Crosby Building, as applicable,;

If a part of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, shall be so acquired or condemned and this Lease and the term shall not be terminated pursuant to this Section 6.2, Landlord, at Landlord’s expense, shall restore that part of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, not so acquired or condemned as nearly as practicable to the condition existing immediately prior to such taking. Upon the termination of this Lease with respect to the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, and the term pursuant to this Section 6.2, the Base Rent and Additional Rent shall be apportioned and any prepaid portion of Base Rent and Additional Rent for any period after such date shall be refunded by Landlord to Tenant.

6.2.2.            Awards. In the event of any such acquisition or condemnation of all or any part of the Lot, Landlord shall be entitled to receive the entire award for any such acquisition or condemnation, Tenant shall have no claim against Landlord or the condemning authority for the value of any unexpired portion of the Term and Tenant hereby expressly assigns to Landlord all of its right in and to any such award. Nothing contained in this Section 6.2 shall be deemed to prevent Tenant from making a separate claim in any condemnation proceedings for the then value of any Tenant’s property included in such taking, and for any moving expenses.

6.2.3.            Access. Following any fire or other casualty, Tenant shall be entitled to immediately access the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, subject to the orders and requirements of local authorities provided that Tenant shall reasonably cooperate with Landlord so to minimize any inconvenience to Landlord and its contractors in the performance of any restoration work or other 18 Crosby Building and/or the 14 Crosby Building, as applicable, recovery.

7.2.         Termination of the Lease.

7.2.1.            If an Event of Default: (i) described in 7.1.5 hereof shall occur; or (ii) described in 7.1, 7.1.1, 7.1.2, 7.1.3, 7.1.4, 7.1.6, 7.1.7, 7.1.8, 7.1.9 or 7.1.10 shall occur and Landlord, at any time thereafter, at its option gives written notice to Tenant stating that this Lease and the term shall expire and terminate on the date Landlord shall give Tenant such notice, such date being a date not less than three (3) days after the giving of such notice, then this Lease and the term and all rights of Tenant under this Lease shall expire and terminate as if the date on which the Event of Default described in clause (i) above occurred or the date of such notice pursuant to clause (ii) above, as the case may be, were the expiration date or the last day of the Extension Term (as defined in Section 8.15), as the case may be, and Tenant immediately shall quit and surrender the entire Premises, but Tenant shall nonetheless be liable for all of its obligations under this Lease. Anything contained herein to the contrary notwithstanding, if such termination shall be stayed by order of any court having jurisdiction over any proceeding described in 7.1.5 hereof, or by federal or state statute, then, following the expiration of any such stay, or if the trustee appointed in any such proceeding, Tenant or Tenant as debtor-in-possession shall fail to assume Tenant’s obligations under this Lease within the period prescribed therefor by law or within thirty (30) days after entry of the order for relief or as may be allowed by the court.

7.2.2.            If an Event of Default described in Section 7.1.1 hereof shall occur, or this Lease shall be terminated as provided in Section 7.2 hereof, Landlord, without notice, may, to the fullest extent of the law, reenter and repossess, without being deemed guilty of any manner of trespass, the Premises using such force for that purpose as may be necessary without being liable to indictment, prosecution or damages therefor and may dispossess Tenant by summary proceedings or otherwise.

7.2.3.            In the event of any such termination, entry or re-entry, Landlord shall have the rights to remove and store Tenant’s Property and that of persons claiming by, through or under Tenant, at the sole risk and expense of Tenant and, if Landlord so elects, (x) to sell such Tenant’s Property at public auction or private sale and apply the net proceeds to the payment of all sums due to Landlord from Tenant and pay the balance, if any, to Tenant, or (y) to dispose of such Tenant’s Property in any manner in which Landlord shall elect, Tenant hereby agreeing to the fullest extent permitted by law that it shall have no right, title or interest in any property remaining in the Premises after such termination, entry or re-entry.

7.3.         Joint and Several Liability. If at any time:

Any monies received by Landlord from or on behalf of Tenant during the pendency of any proceeding of the types referred to in 7.1.5 shall be deemed paid as compensation for the use and occupation of the Premises and the acceptance of any such compensation by Landlord shall not be deemed an acceptance of Rent or a waiver on the part of Landlord of any rights under this Lease, including Section 7.2. In like manner, if Tenant shall be a partnership or other business association, the members of which are, by virtue of statute or federal Law, subject to personal liability, then the liability of each such member shall be joint and several.

7.4.          Landlord’s Remedies.

7.4.1.            If there shall occur any Event of Default, and this Lease and the term shall expire and come to an end as provided in Section 7 hereof:

Tenant shall quit and peacefully surrender the entire Premises to Landlord, and Landlord and its agents may immediately, or at any time after such default or after the date upon which this Lease and the Term shall expire and come to an end, re-enter the Premises or any part thereof, without notice, either by summary proceedings, or by any other applicable action or proceeding, or by force or otherwise (without being liable to indictment, prosecution or damages therefor), and may repossess the Premises and dispossess Tenant and any other persons from the Premises and remove any and all of their property and effects from the Premises; and

Landlord, at Landlord’s option, may relet the whole or any portion or portions of the Premises from time to time, either in the name of Landlord or otherwise, to such tenant or tenants, for such term or terms ending before, on or after the expiration date, at such rental or rentals and upon such other conditions, which may include concessions and free rent periods, as Landlord, in its sole discretion, may determine; provided, however, THAT LANDLORD SHALL HAVE NO OBLIGATION TO RELET THE PREMISES OR ANY PART THEREOF AND SHALL IN NO EVENT BE LIABLE FOR REFUSAL OR FAILURE TO RELET THE PREMISES OR ANY PART THEREOF, OR, IN THE EVENT OF ANY SUCH RELETTING, FOR REFUSAL OR FAILURE TO COLLECT ANY RENT DUE UPON ANY SUCH RELETTING, AND NO SUCH REFUSAL OR FAILURE SHALL OPERATE TO RELIEVE TENANT OF ANY LIABILITY UNDER THIS LEASE OR OTHERWISE AFFECT ANY SUCH LIABILITY, and Landlord, at Landlord’s option, may make such repairs, replacements, alterations, additions, improvements, decorations and other physical changes in and to the Premises as Landlord, in its sole discretion, considers advisable or necessary in connection with any such reletting or proposed reletting, without relieving Tenant of any liability under this Lease or otherwise affecting any such liability.

Notwithstanding the foregoing, Landlord will use reasonable efforts to relet the Premises after Tenant vacates the Premises; however, the marketing and leasing of the Premises in a manner similar to the manner in which Landlord markets and leases other premises within Landlord’s control in the Building shall be deemed to have satisfied Landlord’s obligation to use “reasonable efforts”. In no event shall Landlord be required to (i) solicit or entertain negotiations with any other prospective tenants for the Premises unless and until Landlord obtains full and complete possession of the Premises, including the final and unappealable legal right to relet the Premises free of any claim of Tenant, (ii) lease the Premises to a tenant whose proposed use, in Landlord’s reasonable judgment, will be unacceptable, (iii) relet the Premises prior to leasing any other vacant space in the Building, suitable for the use of the prospective tenant, (iv) lease the Premises for a rental rate less than the current fair market rent then prevailing for similar space in the Building, or (v) enter into a lease with any proposed tenant that does not have, in Landlord’s reasonable but good faith opinion, sufficient financial wherewithal and resources to satisfy its financial obligations under the prospective lease.

Tenant shall pay Landlord, on demand, all past due Rent and other losses and damages Landlord suffers as a result of Tenant’s Default, including, without limitation, all Costs of Reletting (defined below) and any deficiency that may arise from reletting or the failure to relet the Premises. “Costs of Reletting” shall include all reasonable costs and expenses incurred by Landlord in reletting or attempting to relet the Premises, including, without limitation, legal fees, brokerage commissions, the cost of alterations and the value of other concessions or allowances granted to a new tenant. Landlord shall be entitled to take into account in connection with any such reletting of the Premises all relevant factors which would be taken into account by a sophisticated landlord in securing a replacement tenant for the Premises including the first class quality of the Property, matters of tenant mix, and the financial responsibility of any such replacement tenant.

Tenant hereby waives the service of any notice of intention to re-enter or to institute legal proceedings to that end which may otherwise be required to be given under any present or future law. Tenant, on its own behalf and on behalf of all persons claiming through or under Tenant, including all creditors, does further hereby waive any and all rights which Tenant and all such persons might otherwise have under any present or future law to redeem the Premises, or to re-enter or repossess the Premises, or to restore the operation of this Lease, after (i) Tenant shall have been dispossessed by a judgment or by warrant of any court or judge, or (ii) any re-entry by Landlord, or (iii) any expiration or termination of this Lease and the term, whether such dispossess, re-entry, expiration or termination shall be by operation of law or pursuant to the provisions of this Lease. The words “re-enter,” “re-entry” and “re-entered” as used in this Lease shall not be deemed to be restricted to their technical legal meanings. In the event of a breach or threatened breach by Tenant, or any persons claiming through or under Tenant, of any term, covenant or condition of this Lease, Landlord shall have the right to enjoin such breach and the right to invoke any other remedy allowed by law or in equity as if re-entry, summary proceedings and other special remedies were not provided in this Lease for such breach. The right to invoke the remedies hereinbefore set forth are cumulative and shall not preclude Landlord from invoking any other remedy allowed at law or in equity.

7.5.          Landlord’s Damages.

7.5.1.            If this Lease and the Term shall expire and come to an end as provided in Section 7.2 hereof, or by or under any summary proceeding or any other action or proceeding, or if Landlord shall re-enter the Premises as provided in 7.4, or by or under any summary proceeding or any other action or proceeding, then, in any of said events:

Tenant shall pay to Landlord all Base Rent, Additional Rent and other items of Rent payable under this Lease with respect to the entire Premises by Tenant to Landlord to the date upon which this Lease and the term shall have expired and come to an end or to the date of re-entry upon the Premises by Landlord, as the case may be;

Tenant also shall be liable for and shall pay to Landlord, as damages, any deficiency (referred to as “Deficiency”) between the Rent with respect to the entire Premises for the period which otherwise would have constituted the unexpired portion of the Term and the net amount, if any, of rents collected under any reletting effected pursuant to the provisions of clause (ii) of 7.4 for any part of such period (first deducting from the rents collected under any such reletting all of Landlord’s expenses in connection with the termination of this Lease, Landlord’s re-entry upon the Premises and with such reletting, including, but not limited to, all repossession costs, brokerage commissions, legal expenses, attorneys’ fees and disbursements, alteration costs, contribution to work and other expenses of preparing the Premises for such reletting); any such Deficiency shall be paid in monthly installments by Tenant on the days specified in this Lease for payment of installments of Base Rent; Landlord shall be entitled to recover from Tenant each monthly Deficiency as the same shall arise, and no suit to collect the amount of the Deficiency for any month shall prejudice Landlord’s right to collect the Deficiency for any subsequent month by a similar proceeding; and

whether or not Landlord shall have collected any monthly Deficiency as aforesaid, Landlord shall be entitled to recover from Tenant, and Tenant shall pay to Landlord, on demand, in lieu of any further Deficiency as and for liquidated and agreed final damages, a sum equal to the amount by which the Rent with respect to the entire Premises for the period which otherwise would have constituted the unexpired portion of the term (commencing on the date immediately succeeding the last date with respect to which a Deficiency, if any, was collected) exceeds the then fair and reasonable rental value of the Premises for the same period; if, before presentation of proof of such liquidated damages to any court, commission or tribunal, the Premises, or any part thereof, shall have been relet by Landlord for the period which otherwise would have constituted the unexpired portion of the term, or any part thereof, the amount of rent reserved upon such reletting shall be deemed, prima facie, to be the fair and reasonable rental value for the part or the whole of the Premises so relet during the term of the reletting.

7.5.2.            If the Premises, or any part thereof, shall be relet together with other space in the 18 Crosby Building and/or the 14 Crosby Building, as applicable, then the rents collected or reserved under any such reletting and the expenses of any such reletting shall be equitably apportioned for the purposes of this Section 7.5. Tenant shall in no event be entitled to any rents collected or payable under any reletting, whether or not such rents shall exceed the Base Rent reserved in this Lease. Nothing contained herein shall be deemed to limit or preclude the recovery by Landlord from Tenant of the maximum amount allowed to be obtained as damages by any statute or rule of law, or of any sums or damages to which Landlord may be entitled in addition to the damages set forth in this Section 7.5.

ARTICLE VIII.

MISCELLANEOUS

8.1.          Security Deposit. Simultaneous with the execution and delivery of this Lease, Tenant has delivered to Landlord the Security Deposit in the form of a letter of credit (“Letter of Credit”) in the amount as set forth Article 1.1 of this Lease, as security for the full and timely performance of Tenant’s obligations under the terms of this Lease.

8.1.1.            The Security Deposit is not an advance payment of Rent or a measure of damages. Landlord may from time to time and without prejudice to any other remedy provided in this Lease or by Law, use all or a portion of the Security Deposit to the extent necessary to satisfy past due Rent or to satisfy any other loss or damage resulting from Tenant’s breach under this Lease. If Landlord uses any portion of the Security Deposit, Tenant, within five (5) days after demand, shall restore the Security Deposit to its original amount, subject to all terms and conditions set forth in Section 8.1.3. If Tenant fully and faithfully complies with all the covenants hereunder, Landlord shall return any unapplied portion of the Security Deposit to Tenant within forty-five (45) days after the later to occur of: (a) determination of the final Rent due from Tenant; or (b) the later to occur of the expiration date or the date Tenant surrenders the entire Premises to Landlord in compliance with the terms and conditions of this Lease. Landlord may deliver or transfer the Security Deposit (or related letter of credit) to any purchaser of Landlord’s interest in the Premises or any successor Landlord, if applicable, and thereupon Landlord shall be discharged from any further liability with respect to the Security Deposit.

8.1.2.            The Letter of Credit shall: (a) be in the amount set forth in Article 1.1 of this Lease); (b) name Landlord as its beneficiary; (c) be drawn on an FDIC insured financial institution reasonably satisfactory to the Landlord that satisfies both the Minimum Rating Agency Threshold and the Minimum Capital Threshold (as those terms are defined below); and (d) otherwise be in form and content satisfactory to Landlord. The “Minimum Rating Agency Threshold” shall mean that the issuing bank has outstanding unsecured, uninsured and unguaranteed senior long-term indebtedness that is then rated (without regard to qualification of such rating by symbols such as “+” or “-” or numerical notation) “Baa” or better by Moody’s Investors Service, Inc. and/or “BBB” or better by Standard & Poor’s Rating Services, or a comparable rating by a comparable national rating agency designated by Landlord in its discretion. The “Minimum Capital Threshold” shall mean that the Issuing Bank has combined capital, surplus and undivided profits of not less than $10,000,000,000. The Letter of Credit (and any renewals or replacements thereof) shall be for a term of not less than one (1) year. If the issuer of the Letter of Credit gives notice of its election not to renew such Letter of Credit for any additional period, Landlord shall give notice to Tenant of such non-renewal of the Letter of Credit and Tenant shall be required to deliver a substitute Letter of Credit satisfying the conditions hereof at least thirty (30) days prior to the expiration of the term of such Letter of Credit. If the issuer of the Letter of Credit fails to satisfy either or both of the Minimum Rating Agency Threshold or the Minimum Capital Threshold, Tenant shall be required to deliver a substitute letter of credit from another issuer reasonably satisfactory to the Landlord and that satisfies both the Minimum Rating Agency Threshold and the Minimum Capital Threshold not later than ten (10) Business Days after Landlord notifies Tenant of such failure. Tenant agrees that it shall from time to time, as necessary, whether as a result of a draw on the Letter of Credit by Landlord pursuant to the terms hereof or as a result of the expiration of the Letter of Credit then in effect, renew or replace the original and any subsequent Letter of Credit so that a Letter of Credit, in the amount required hereunder, is in effect until a date which is at least sixty (60) days after the expiration date of the Lease. If Tenant fails to furnish such renewal or replacement at least sixty (60) days prior to the stated expiration date of the Letter of Credit then held by Landlord, Landlord may, after giving written notice to Tenant, and if Tenant does not then furnish such renewal or replacement within ten (10) days of receipt of such notice, draw upon such Letter of Credit and hold the proceeds thereof (and such proceeds need not be segregated) as a Security Deposit pursuant to the terms of this Article 8. Any renewal or replacement of the original or any subsequent Letter of Credit shall meet the requirements for the original Letter of Credit as set forth above, except that such replacement or renewal shall be issued by a national bank reasonably satisfactory to Landlord at the time of the issuance thereof. If Landlord draws on the Letter of Credit as permitted in this Lease or the Letter of Credit, then, upon demand of Landlord, Tenant shall restore the amount available under the Letter of Credit to its original amount, subject to all terms and conditions set forth in Section 8.1.3, by providing Landlord with an amendment to the Letter of Credit evidencing that the amount available under the Letter of Credit has been restored to its original amount, subject to all terms and conditions set forth in Section 8.1.3 below.

8.1.3.            The initial Letter of Credit shall be delivered by Tenant to Landlord in the full amount of the Security Deposit equal to $918,815.78. In the event that Tenant is not then in default and no prior Event of Default has occurred as of the date that is sixty (60) months following the 14 Crosby Commencement Date, then Tenant may reduce the Letter of Credit to $500,000.00 (the “Revised Letter of Credit”), and Tenant shall immediately deliver to Landlord the Revised Letter of Credit in the amount of $500,000.00.

8.2.         Parking and Loading Dock: Tenant shall have the right to use on a non reserved, first come, first served basis, parking in the parking lot adjacent to the 18 Crosby Building and the 14 Crosby Building, as applicable, (i) with respect to the 18 Crosby Premises, at a ratio of two (2) vehicle spaces per each one thousand (1,000) rentable square feet of the 18 Crosby Premises (equaling one hundred six (106) parking spaces for Tenant’s occupancy of approximately 53,000 rentable square feet), and (ii) with respect to the 14 Crosby Premises, at a ratio of three (3) vehicles spaces per each one thousand (1,000) rentable square feet of the 14 Crosby Premises (equaling ninety-eight (98) parking spaces for Tenant’s occupancy of approximately 32,770 rentable square feet)(“Tenant’s Parking Rights”); provided, however, that Landlord and Tenant hereby acknowledge and agree that Tenant’s Parking Rights shall be reduced by the number of parking spaces that are impacted by the installation of any such Generator in accordance with Article X herein. Tenant’s Parking Rights shall be non-transferable (directly or indirectly) to any other institutions, entities or individuals. Tenant’s use of the Tenant’s Parking Rights shall be limited to normal Building operating hours, and overnight parking at the Building shall be strictly prohibited. Landlord, in Landlord’s sole discretion, may institute a sticker system (the “Sticker System”) in connection with Tenant’s Parking Rights, and Tenant shall be solely responsible for distributing any and all such stickers to Tenant’s employees in connection therewith. Landlord may cause any such illegally parked car or any such car without a parking sticker, if applicable, to be towed from the parking lot, and Landlord may bill the owner of such car for any and all such costs and expenses in connection therewith. Tenant shall use best efforts to comply with any and all policies in connection with this Section 8.2. Notwithstanding anything to the contrary set forth herein, in the event that Tenant requires additional unreserved parking spaces (the “Additional Parking Spaces”), then Tenant shall provide Landlord with written notice of such request, and Landlord shall use reasonable efforts to accommodate Tenant’s needs for such Additional Parking Spaces. Tenant shall be solely responsible, at Tenant’s sole cost and expense, for (i) any and all costs incurred by Landlord or otherwise in connection with providing Tenant such Additional Parking Spaces, and (ii) any and all such other fees, costs, charges, expenses and/or the like in connection with Tenant’s use of such Additional Parking Spaces. Tenant’s use of any such Additional Parking Spaces shall be subject to all terms and conditions of this Lease, including, without limitation, this Section 8.2.

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

8.2.2.            Tenant’s Parking Rights shall be subject to such reasonable rules and regulations therefor as may be set and changed with reasonable prior notice by the Landlord from time to time and uniformly enforced by Landlord during the term. Tenant’s Parking Rights are non-assignable and intended solely for the use of Tenant’s employees working from and business invitees to the Premises; and as such Tenant shall not offer them for “use” or “license” to any other entity, the general public, or any other tenants of the Building. All such appurtenant rights for parking as set forth in this Section are automatically terminated upon termination of this Lease and shall have no separate independent validity or legal standing. Landlord reserves the right to relocate and/or temporarily close any or all of the parking facilities to the extent necessary in the event of a casualty or governmental taking or for maintenance and repairs of the parking facility provided Landlord shall reopen the same or provide replacement parking facilities as soon as practicable thereafter.

8.2.3            18 Crosby Building Loading Dock: Tenant shall have the exclusive right to use the 18 Crosby Building’s loading dock (the “18 Crosby Building Loading Dock”). Tenant’s right to use the 18 Crosby Building Loading Dock shall be non-transferable (directly or indirectly) to any other institutions, entities or individuals, except in connection with an assignment of this Lease or sublease of all or a portion of the Premises pursuant to and in accordance with all terms and conditions of Section 5.6. Landlord shall not be liable for any loss, injury or damage to persons using the 18 Crosby Building Loading Dock or vehicles or other property used in connection therewith, it being agreed that, to the fullest extent permitted by law, the use of the 18 Crosby Building Loading Dock shall be at the sole risk of Tenant and its employees. Tenant shall be solely responsible, at Tenant’s sole cost and expense, for any and all such repair, maintenance, replacement and the like with the respect to the 18 Crosby Building Loading Dock throughout the entire Term of this Lease, as the same may be extended. Use of the 18 Crosby Building Loading Dock shall be subject to such reasonable rules and regulations therefor as may be set and changed with reasonable prior notice by Landlord from time to time. All such appurtenant rights to use the 18 Crosby Building Loading Dock as set forth in this Section are automatically terminated upon termination of this Lease and shall have no separate independent validity or legal standing. Landlord reserves the right to temporarily close the 18 Crosby Building Loading Dock to the extent necessary in the event of a casualty or governmental taking or for maintenance and repairs of the 18 Crosby Building, provided Landlord shall reopen the same as soon as practicable thereafter.

8.3.          Notice of Lease; Consent or Approval; Notices; Bind and Inure; Landlord’s Estate: The titles of the Articles are for convenience only and not to be considered in construing this Lease. The Exhibits attached hereto are incorporated herein by reference. Tenant agrees not to record this Lease, but upon request of either party, both parties shall execute and deliver a notice of this Lease in form appropriate for recording or registration, and if this Lease is terminated before the Term expires, an instrument in such form acknowledging the date of termination. Whenever any notice, approval, consent, request or election is given or made pursuant to this Lease it shall be in writing. Communications and payments shall be addressed if to Landlord at Landlord’s Address or at such other address as may have been specified by prior notice to Tenant; and if to Tenant at Tenant’s Address or at such other place as may have been specified by prior notice to Landlord. Any communication so addressed shall be mailed by registered or certified mail, return receipt requested, postage prepaid, by express mail, by express courier service, or by hand delivery. Notice or payment shall be deemed given when so delivered by hand or, if mailed by registered or certified mail, two days after it is deposited with the U.S. Postal Service, or if sent by express mail or courier service, one day after it is deposited with the U. S. Postal or such other service. If Landlord by notice to Tenant at any time designates some other person to receive payments or notices, all payments or notices thereafter by Tenant shall be paid or given to the agent designated until notice to the contrary is received by Tenant from Landlord. The obligations of this Lease shall run with the land, and this Lease shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, except that each original Landlord named herein and each successive owner of the Premises shall be liable only for obligations accruing during the period of its ownership. If Landlord shall at any time be an individual, joint venture, tenancy in common, firm or partnership (general or limited) a trust or trustees of a trust, it is specifically understood and agreed that there shall be no personal liability of the Landlord or any joint 49enture, tenant, partner, trustee, shareholder, beneficiary or holder of a beneficial interest under any of the provisions hereof or arising out of the use or occupation of the Premises by Tenant. In the event of a breach or default by Landlord of any of its obligations under this Lease, Tenant shall look solely to the then equity of the Landlord in the Property for the satisfaction of Tenant’s remedies, and it is expressly understood and agreed that Landlord’s liability under the terms, covenants, conditions, warranties and obligations of this Lease shall in no event exceed the value of such equity interest.

8.4.          Landlord’s Failure to Enforce: The failure of Landlord or of Tenant to seek redress for violation of, or to insist upon strict performance of, any covenant or condition of this Lease, or, with respect to such failure of Landlord, any of the Rules and Regulations referred to in Section 5.4, whether heretofore or hereafter adopted by Landlord, shall not be deemed a waiver of such violation nor prevent a subsequent act, which would have originally constituted a violation, from having all the force and effect of an original violation of any such Rules or Regulations. The receipt by Landlord of Base Rent or Additional Rent with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver of such breach. No provision of this Lease shall be deemed to have been waived by Landlord, or by Tenant, unless such waiver is in writing signed by the party to be charged. No consent or waiver, express or implied, by Landlord or Tenant to or of any breach of any agreement or duty shall be construed as a waiver or consent to or of any other breach of the same or any other agreement or duty.

8.5.          Acceptance of Partial Payments of Rent; Delivery of Keys: No acceptance by Landlord of a lesser sum than the Base Rent and Additional Rent then due shall be deemed to be other than on account of the earliest installment of such rent, due, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as rent be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such installment or pursue any other remedy in this Lease provided. The delivery of keys to any employee of Landlord or to Landlord’s agent or any employee thereof shall not operate as a termination of this Lease or a surrender of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable.

8.6.         Cumulative Remedies: The specific remedies to which Landlord 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 it may be lawfully entitled in case of any breach or threatened breach by Tenant of any provisions of this Lease. In addition to the other remedies provided in this Lease, 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.

8.7.          Partial Invalidity: If any term of this Lease, or the application thereof, to any person or circumstances, shall to any extent be invalid or unenforceable, the remainder of this Lease, or the application of such term to persons or circumstances other than those to which it is invalid or unenforceable, shall not be affected thereby, and each term of this Lease shall be valid and enforceable to the fullest extent permitted by law.

8.8.          Self-Help: If Tenant shall at any time default in the performance of any obligation under this Lease, Landlord shall have the right, but shall not be obligated, to enter upon the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, or the 18 Crosby Building and/or the 14 Crosby Building, as applicable 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 and all necessary incidental 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.

8.8.1.            Tenant’s Self Help. If Landlord shall default in the performance of any material obligation expressly contained in this Lease, and if Landlord shall not cure such default within thirty (30) days after written notice from Tenant specifying the default (or, if such default shall reasonably take more than thirty (30) days to cure, and Landlord shall not have commenced the same within the thirty (30) day period), Tenant may, at its option, cure such default and any amount paid by Tenant, evidenced by invoices and receipts, in remedying such default shall be reimbursed by Landlord to Tenant within forty-five (45) days after written notice to Landlord. If Landlord shall fail to reimburse Tenant with the said forty-five (45) day period, said amount may be deducted from the next payment of Base Rent; provided, however, that should said amount or the liability therefor be disputed by Landlord, Landlord may contest its liability or the amount thereof, through arbitration or through a declaratory judgment action.

8.9.          Estoppel Certificate: From time to time, within ten (10) days next following request by Landlord, Tenant shall deliver to Landlord a written statement executed by Tenant, in form satisfactory to Landlord:

8.9.1.            stating that this Lease is then in full force and effect and has not been modified (or if modified, setting forth all modifications);

8.9.2.            setting forth the date to which the Base Rent and Additional Rent have been paid;

8.9.3.            stating whether or not, to the best knowledge of Tenant, Landlord is in default under this Lease, and, if Landlord is in default, setting forth the specific nature of all such defaults; and

8.9.4.            certifying as to any other matters reasonably requested by Landlord.

Tenant’s failure to execute and deliver such statement within five (5) days of such time shall, at the option of Landlord, constitute a material default under this Lease and, in any event, shall be conclusive upon Tenant that this Lease is in full force and effect without modification except as may be represented by Landlord in any such certificate prepared by Landlord and delivered to Tenant for execution. Tenant acknowledges that any statement delivered pursuant to this Section 8.9 may be relied upon by any purchaser or owner of the Property, Office Park, Lot or the Building, or Landlord’s interest in the Property, Office Park, Lot or the Building, or by any mortgage, or by an assignee of any mortgage, of the Property, Office Park, Lot or the Building.

8.10.        Waiver of Subrogation: Any insurance carried by either party, or required to be carried by either party, with respect to the 18 Crosby Premises and the 14 Crosby Premises, as applicable, or property therein or occurrences thereon shall include a clause or endorsement denying to the insurer rights of subrogation against the other party to the extent rights have been waived by the insured prior to occurrence of injury or loss. Each party, notwithstanding any provisions of this Lease to the contrary, hereby waives any rights of recovery against the other for injury or loss due to hazards covered by, or required to be covered by, such insurance.

8.11.        All Agreements Contained: This Lease contains all of the agreements of the parties with respect to the subject matter thereof and supersedes all prior dealings between them with respect to such subject matter.

8.12.        Brokerage: Landlord and Tenant warrant to each other that they have had no dealings with any broker or agent in connection with this Lease other than Jones Lang LaSalle and Avison Young (the “Broker(s)”), and covenant to defend with counsel approved by the other, hold harmless and indemnify the other from and against any and all cost, expense or liability for any compensation, commissions and charges claimed by any other broker or agent with respect to this Lease or the negotiation thereof. Landlord shall be responsible for payment of fees to Broker(s) per a separate agreement.

8.13.        Submission Not an Option: The submission of this Lease or a summary of some or all of its provisions for examination does not constitute a reservation of or option of the Premises or an offer to lease and it is not effective as a lease or otherwise until execution by and delivery to both Landlord and Tenant.

8.14.        Transfer for Landlord: In the event of a sale or conveyance by Landlord of the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, the same shall operate to release Landlord from any future liability for any of the covenants or conditions, express or implied, herein contained in favor of Tenant with respect to the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, and in such event Tenant agrees to look solely to Landlord’s successor in interest with respect thereto and agrees to attorn to such successor.

8.15.        Option to Extend Term.

8.15.1.          Provided (a) that there has not been an Event of Default (as defined in Article 7 of this Lease), (b) this Lease is still in full force and effect, and (c) Tenant is occupying one hundred percent (100%) of the entire Premises (except with respect to (a) a Permitted Transfer or (b) a sublease (which does not fall under the definition of Permitted Transfer) of 20,000 rentable square feet or less of the entire Premises), Tenant shall have the option to extend the term of this Lease with respect to the entire Premises for two (2) successive five (5) year periods (the “Extension Terms”, each an “Extension Term”) commencing on the day immediately succeeding the expiration date of the then current term, under the same terms, covenants and conditions contained in this Lease (except that Landlord shall not be obligated to refurbish the either the 18 Crosby Premises or the 14 Crosby Premises, nor provide any allowance therefor, and there shall be no further extension options for a third option term); provided, however, that (i) the Base Rent for the first (1^st) Extension Term with respect to the 18 Crosby Premises and the 14 Crosby Premises, as applicable, shall be equal to the greater of (a) the Base Rent in effect during the last year of the initial Lease term with respect to the 18 Crosby Premises and the 14 Crosby Premises, as applicable, and (b) ninety-five percent (95%) of the Fair Market Rent for comparable space in the 18 Crosby Building and the 14 Crosby Building, as applicable, and the Bedford/Lexington/Burlington lab and office submarket, having due regard for the size, location and use of the 18 Crosby Premises and the 14 Crosby Premises, as applicable, and (ii) the Base Rent for the second (2^nd) Extension Term with respect to the 18 Crosby Premises and the 14 Crosby Premises, as applicable, shall be equal to the greater of (y) the Base Rent in effect during the last year of the then current term with respect to the 18 Crosby Premises and the 14 Crosby Premises, as applicable, and (z) the Fair Market Rent for comparable space in the 18 Crosby Building and the 14 Crosby Building, as applicable, and the Bedford/Lexington/Burlington lab and office submarket, having due regard for the size, location and use of the 18 Crosby Premises and the 14 Crosby Premises, as applicable. Regardless of whether the Base Rent with respect to the 18 Crosby Premises or the 14 Crosby Premises, as applicable, for the applicable Extension Term is calculated based on (a), (b), (y), or (z), as applicable, above in this Section 8.15.1, the Base Rent with respect to the 18 Crosby Premises or the 14 Crosby Premises, as applicable, of the applicable Extension Term shall include annual increases consistent with Fair Market Rent increases at the time of Tenant’s renewal exercise. In the event Tenant exercises its option to extend the then current term as provided herein, the expiration date shall be that date which is the last day of the applicable Extension Term, and Landlord and Tenant shall thereupon execute an amendment to this Lease in form satisfactory to Landlord (the “Extension Term Amendment”) extending the expiration date to this Lease and modifying the Base Rent with respect to the 18 Crosby Premises or the 14 Crosby Premises, as applicable, in accordance with the provisions of this Section.

8.15.2.           If Tenant desires to exercise its options to extend the Term with respect to the entire Premises as contained in this Section, time being of the essence, Tenant shall provide Landlord written notice not sooner than eighteen (18) months, and not later than twelve (12) months prior to the expiration date of the then current Term.

8.15.3.           “Fair Market Rent” shall mean the fair market rent, including concessions (and taking into account all market factors) that would be agreed upon between a landlord and a tenant entering into a new lease for comparable space in the 18 Crosby Building and the 14 Crosby Building, as applicable, and in the Bedford/Lexington/Burlington lab and office submarket as to location, size and use, in a comparable building assuming the premises are in their then as-is condition, a comparable term and comparable operating expenses and real estate taxes, assuming that the landlord and the tenant are informed and well-advised and each is acting in what it considers its own best interests. Landlord and Tenant shall negotiate in good faith to determine the Fair Market Rent for the applicable Extension Term for a period of thirty (30) days after the date on which Landlord receives Tenant’s written notice of Tenant’s election to extend the term, as provided hereunder.

8.15.4            In the event Landlord and Tenant are unable to agree upon the Fair Market Rent for the applicable Extension Term within said thirty (30) day period, the Fair Market Rent shall be determined by a board of three (3) licensed commercial real estate appraisers, each having at least ten (10) years’ experience in leasing in the Bedford/Lexington/Burlington lab and office submarket, one of whom shall be named by Landlord, one of whom shall be named by Tenant, and the two so appointed shall select the third. Landlord and Tenant agree to make their appointments within fifteen (15) days after the expiration of said thirty (30) day period. The two appraisers selected by Landlord and Tenant shall select the third appraiser within fifteen (15) days after they have both been selected, and each of Landlord’s and Tenant’s appraiser shall, within fifteen (15) days after the third appraiser is selected, submit his or her determination of Fair Market Rent to the third appraiser. The third appraiser shall select the determination of Landlord’s or Tenant’s appraiser that such third appraiser finds to most closely resemble Fair Market Rent, and that amount shall be the Base Rent with respect to the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, during the Extension Term. Each party shall bear the cost of its appraiser and the parties shall share equally in the cost of the third appraiser. In the event that Fair Market Rent has not been determined as of the start of the applicable Extension Term, then Base Rent with respect to the 18 Crosby Premises and the 14 Crosby Premise, as applicable, shall be paid at the rate payable immediately prior thereto, and an adjustment, retroactive to the start of the applicable Extension Term, shall be made once Fair Market Rent is known. Notwithstanding anything contained herein to the contrary, if an Event of Default (as defined in Article 7) with respect to either the 18 Crosby Premises and/or the 14 Crosby Premises, as applicable, occurs at any time after the Tenant’s written exercise of the applicable extension option, Landlord may elect, at Landlord’s sole discretion by written notice to Tenant, to reject Tenant’s exercise of such extension option. If Landlord so rejects Tenant’s exercise of the extension option, such extension option shall be null and void.

8.16.        Intentionally Omitted.

8.17.        Right of First Offer^.

8.17.1.          Subject to the terms and conditions set forth below and as otherwise set forth herein, as applicable, in the event that Landlord, in Landlord’s sole and unfettered discretion, elects to expand the 18 Crosby Building, then Tenant shall have the one-time right of first offer (the “ROFO”) to expand the 18 Crosby Premises by leasing at least 50,000 rentable square feet of space in the 18 Crosby Building, but no more than 70,000 rentable square feet of space in the 18 Crosby Building (the “ROFO Space”), subject to the Town of Bedford’s approval of the site plan and subject to Landlord’s receipt of all necessary permits, approvals and the like.

8.17.2.          Tenant shall have the right to exercise its ROFO with respect to the ROFO Space at any time within the twelve (12) month period following the 18 Crosby Commencement Date (the “ROFO Commencement Date”). During the period of time beginning as of the ROFO Commencement Date and ending as on the date that is twelve (12) months following the ROFO Commencement Date (the “ROFO Expiration Date”), (i) Landlord shall not market the ROFO Space to any prospective tenants, and (ii) Landlord and Tenant shall work in tandem and harmoniously towards generating a site plan for the Town of Bedford’s approval, subject to Landlord and Tenant’s reasonable approval, as well as other necessary and incidental items with respect thereto. In the event that Tenant timely exercises its ROFO with respect to the ROFO Space, then (i) the term of the Lease with respect to the entire Premises shall be extended for ninety-six (96) months such that the term of this Lease with respect to the entire Premises shall expire on that date that is ninety-six (96) months following the 18 Crosby Expiration Date, and the Base Rent for the 18 Crosby Premises and the 14 Crosby Premises, as applicable, shall be increased using the annual escalation rate as contained in this Lease, and (ii) Base Rent for the ROFO Space shall be based on a lease constant of nine percent (9%) on the total project costs with respect to the ROFO Space and the expansion of the 18 Crosby Building associated therewith, including, without limitation, market rate land value and hard and soft costs; provided, however, that in the event that Tenant expands the 18 Crosby Building, Landlord shall remove the remaining $300,000.00 from the nine percent (9%) return on cost factor as negotiated and shall be Landlord’s sole cost. In addition, in the event that Tenant timely notifies Landlord that it wishes to lease the ROFO Space, then Landlord and Tenant shall promptly, but in no event later than thirty (30) days after Tenant’s timely notice, execute an amendment to this Lease in form satisfactory to Landlord (the “ROFO Space Amendment”) incorporating the ROFO Space into the entire Premises, extending the term of this Lease with respect to the entire Premises by ninety-six (96) months, and modifying any and all other applicable terms and conditions contained in this Lease.

8.17.3.          If Tenant fails to timely notify Landlord within said twelve (12) month period of time following the ROFO Commencement Date as set forth in Section 8.17.2 that Tenant intends to lease such ROFO Space, or if Tenant fails to timely execute the ROFO Space Amendment, then Tenant shall be deemed to have waived its rights with respect to the ROFO Space and Landlord shall be entitled to lease, at its sole discretion and without any further notice to Tenant, all or any portion of such ROFO Space to any third party or parties on such terms and conditions, including, without limitation, options to extend the term of such lease and/or expand the premises under such lease, and for such rent as Landlord determines, all in its sole discretion, and the ROFO with respect to any such space shall be of no further force or effect; provided, however, that if Landlord shall receive a bona fide offer (the “Offer”) from a prospective tenant to lease all or any part of the ROFO Space after said twelve (12) month period of time, Landlord shall give Tenant written notice of such fact. Landlord’s notice shall specify all material terms and conditions of the Offer. Tenant, by written notice to Landlord, will notify Landlord within five (5) Business Days of Landlord’s notice if Tenant wishes to lease such ROFO Space from Landlord on the terms and conditions so specified in the Offer. If Tenant notifies Landlord that it wishes to lease the ROFO Space pursuant to and in connection with the Offer, then Landlord and Tenant shall execute an amendment to this Lease in a form provided by Landlord incorporating such ROFO Space into the entire Premises upon the terms contained in the Offer within five (5) Business Days thereafter, and the term of the Lease with respect to the entire Premises shall be extended for ninety-six (96) months such that the term of this Lease with respect to the entire Premises shall expire on that date that is ninety-six (96) months following the 18 Crosby Expiration Date, and the Base Rent for the 18 Crosby Premises and the 14 Crosby Premises, as applicable, shall be increased using the annual escalation rate as contained in this Lease. If Tenant timely exercises such option as set forth in this Section 8.17.3, Landlord will deliver such space to Tenant at the time the space was to be delivered to the prospective tenant under the Offer. If Tenant fails to notify Landlord within said five (5) Business Day period that Tenant intends to lease such ROFO Space, or fails to execute a lease amendment for such ROFO Space within five (5) Business Days of Tenant’s notice of intent to Landlord, or notifies Landlord that Tenant does not wish to lease the ROFO Space pursuant to the terms and conditions contained in the Offer, then Tenant shall be deemed to have waived its rights with respect to the ROFO Space and Landlord shall be entitled to lease, at its sole discretion and without any further notice to Tenant, in whole or in part, the ROFO Space to the prospective tenant identified in such Offer on the terms set forth in the Offer or on terms for a Net Effective Rate (as defined hereinafter) which is not lower than that offered to Tenant pursuant to the Offer by more than ten percent (10%); it being hereby agreed that, as used herein, the term “Net Effective Rate” shall mean the actual rental rate to be received per year, on the average, during the proposed term determined by deducting from the face rental value for the term thereof the dollar value of all inducements, free rent, tenant improvements and other concessions proposed to be given.

8.17.4.         Notwithstanding any contrary provision of this Section 8.17 or any other provision of this Lease, any ROFO and any exercise by Tenant of any right set forth in this Section shall be void and of no effect unless on the date Tenant notifies Landlord that it is exercising the ROFO or on the date that Tenant notifies Landlord that it wishes to lease the ROFO Space as Section forth in Section 8.17.3 herein, as applicable, and on the commencement date of the amendment for the ROFO Space (i) this Lease is in full force and effect and (ii) no Event of Default has occurred under this Lease and (iii) except in connection with a Permitted Transfer, Tenant shall not have assigned this Lease, and there shall not be any sublease or subleases in effect as of the commencement of the term of the Lease for any of the ROFO Space as of the date of Landlord’s notice of the ROFO Space availability.

8.17.5          If Landlord elects to expand the 18 Crosby Building and leases such space to another tenant other than Tenant, the design and the construction of the 18 Crosby Building expansion shall not unreasonably interfere with Tenant’s access to or operations in the 18 Crosby Building. Landlord shall use commercially reasonable efforts to minimize interference with Tenant’s access to or operations in the 18 Crosby Building during the performance of any such work by or on behalf of Landlord in connection with any such 18 Crosby Building expansion work.

8.18.        Landlord’s Property. Subject to Section 8.19 below, all fixtures, machinery, equipment, improvements and appurtenances attached to, or built into, the Premises at the commencement of, or during the Term, whether or not placed there by or at the expense of Tenant, shall become and remain a part of the Premises; shall be deemed the property of Landlord (the “Landlord’s Property”), without compensation or credit to Tenant; and shall not be removed by Tenant unless Landlord requests their removal in accordance with the provisions of this Lease. Further, any personal property in the Premises on the 18 Crosby Commencement Date and/or the 14 Crosby Commencement Date, as applicable, movable or otherwise, unless installed and paid for by Tenant, shall be and shall remain the property of Landlord and shall not be removed by Tenant. In no event shall Tenant remove any of the following materials or equipment without Landlord’s prior written consent: any power wiring or power panels, lighting or lighting fixtures, wall or window coverings, carpets or other floor coverings, heaters, air conditioners or any other HVAC equipment, fencing or security gates, or other similar Building operating equipment and decorations.

8.19.        Tenant’s Property. All movable non-structural partitions, business and trade fixtures, machinery and equipment, communications equipment and office equipment, that are installed in the Premises by, or for the account of, Tenant without expense to Landlord and that can be removed without structural damage to the Property and/or Building, and all furniture, furnishings and other articles of movable personal property owned by Tenant and located in the Premises (collectively, the “Tenant’s Property”) shall be and shall remain the property of Tenant and may be removed by Tenant at any time during the term, provided that Tenant repairs or pays the cost of repairing any damage to the Premises, Building or Property resulting from the installation and/or removal thereof. At or before the expiration date, or the date of any earlier termination, Tenant, at its expense, shall remove from the Premises (i) all of Tenant’s Property, and (ii) any alterations, if any, as agreed in writing in accordance with Section 5.2 hereof, and Tenant shall repair any damage to the Premises, Building or Property resulting from any installation and/or removal of such property. If Tenant fails to remove any of Tenant’s Property, or to restore the Premises to the required condition, within three (3) days after termination of this Lease or Tenant’s right to possession, Landlord, at Tenant’s sole cost and expense, shall be entitled (but not obligated) to remove and store Tenant’s Property and/or perform such restoration of the Premises. Landlord shall not be responsible for the value, preservation or safekeeping of Tenant’s Property. Tenant shall pay Landlord, upon demand, the expenses and storage charges incurred. If Tenant fails to remove Tenant’s Property from the Premises or storage, within thirty (30) days after notice, Landlord may deem all or any part of Tenant’s Property to be abandoned and, at Landlord’s option, title to Tenant’s Property shall vest in Landlord or Landlord may dispose of Tenant’s Property in any manner Landlord deems appropriate.

8.20.        Waiver. Tenant hereby waives the right to recover from Landlord any incidental, statutory, indirect, consequential, special or punitive damages, loss of profits or revenue.

8.21.        Intentionally Omitted.

8.22.        Counterparts. This Lease may be executed in any number of counterparts (including facsimiles), each of which will be deemed an original, but all of which will be deemed one and the same instrument.

8.23.        Miscellaneous.

Time is of the essence with regard to this Lease and all of its provisions.

This Lease shall be interpreted and enforced in accordance with the Laws of the Commonwealth of Massachusetts and Landlord and Tenant hereby irrevocably consent to the jurisdiction and proper venue of the Commonwealth of Massachusetts.

If Landlord is advised by its counsel at any time that any part of the payments by Tenant to Landlord under this Lease may be characterized as unrelated business income under the United States Internal Revenue Code and its regulations, then Tenant shall enter into any amendment proposed by Landlord to avoid such income, so long as the amendment does not require Tenant to make more payments or accept fewer services from Landlord, than this Lease provides.

This Lease may be modified only by a written agreement signed by an authorized representative of Landlord and Tenant.

Permission to Use Tenant’s Logo: Tenant hereby grants to Landlord’s affiliate, Jumbo Capital Incorporated, a non-exclusive, limited and revocable license to use and display Tenant’s word marks, tradenames or logo (“Tenant’s Logo”) in electronic form on Landlord’s website (the “Permitted Platform”) for the purpose of identifying Tenant as a tenant of Landlord’s building (the “Permitted Purpose”). Such license shall terminate upon the earlier of the date that is thirty (30) days following (a) Landlord’s receipt of Tenant’s written request to terminate such license or (b) the expiration or termination of the Lease. Upon termination of such license, Landlord shall refrain from further use of Tenant’s Logo for the Permitted Purpose on the Permitted Platform.

ARTICLE IX.

SUBORDINATION

9.1.          Subordination: This Lease shall be subject and subordinate to any first mortgage now or hereafter on the Lot, the Office Park or Building, or any combination thereof, which are separately and together hereinafter in this Article IX referred to as the “mortgaged premises,” 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 therefore. This Section 9.1 shall be self- operative and no further instrument of subordination shall be required; however, Tenant shall execute and deliver promptly any instrument, in recordable form if requested by Landlord or any mortgagee, that Landlord, any Lessor or mortgagee may request to evidence and confirm such subordination. Upon Tenant’s written request, but no more than once per any such calendar year, Landlord agrees to use commercially reasonable efforts to have any mortgagee of the Lot, the Office Park or Building, enter into such mortgagee’s standard nondisturbance agreement with Tenant, provided that Tenant is not then in default under this Lease and agrees to pay any charges or fees (including reasonable attorneys’ fees) which may be required by such mortgagee or Landlord in order to obtain such agreement. Tenant shall not do anything that would constitute a default under any mortgage of the mortgaged premises, or omit to do anything that Tenant is obligated to do under the terms of this Lease so as to cause Landlord to be in default thereunder. If, in connection with the financing of the Property, the Office Park, the Lot or the Building, or if any lending institution or Lessor shall request reasonable modifications of this Lease that do not increase Tenant’s monetary obligations under this Lease, or materially adversely affect or diminish the rights, or materially increase the other obligations of Tenant under this Lease, Tenant shall make such modifications.

9.2.          Attornment. If at any time prior to the expiration of the term, any mortgagee comes into possession of the Property, the Lot, the Office Park or the Building, as applicable, or the estate created by receiver or otherwise, Tenant agrees, at the election and upon demand of any owner of the Property, the Lot, the Office Park or the Building, or of the Landlord, or of any mortgagee in possession of the Property, the Lot, the Office Park or the Building, to attorn, from time to time, to any such owner, Landlord or mortgagee or any person acquiring the interest of Landlord as a result of any such termination, or as a result of a foreclosure of the mortgage or the granting of a deed in lieu of foreclosure, upon the then executory terms and conditions of this Lease, for the remainder of the term, provided that such owner, landlord or mortgagee, or receiver caused to be appointed by any of the foregoing, as the case may be, shall then be entitled to possession of the Premises, as applicable, and provided further that such owner, landlord or mortgagee, as the case may be, or anyone claiming by, through or under such owner, landlord or mortgagee, as the case may be, including a purchaser at a foreclosure sale, shall not be:

9.2.1.            liable for any act or omission of any prior landlord (including, without limitation, the then defaulting landlord); or

9.2.2.            subject to any defense or offsets which Tenant may have against any prior landlord (including, without limitation, the then defaulting landlord); or

9.2.3.            bound by any payment of Rent that Tenant may have made to any prior landlord (including, without limitation, the then defaulting landlord) more than thirty (30) days in advance of the date upon which such payment was due; or

9.2.4.            bound by any obligation to make any payment to or on behalf of Tenant; or

9.2.5.            bound by any obligation to perform any work or to make improvements to the Premises, except for:

repairs and maintenance pursuant to applicable provisions of this Lease, the need for which repairs and maintenance first arises after the date upon which such owner, lessor, or mortgagee shall be entitled to possession of the Premises;

repairs to the Premises, as applicable, or any part thereof as a result of damage by fire or other casualty, or taking, pursuant to Section 6.1 hereof, but only to the extent that such repairs can be reasonably made from the net proceeds of any insurance actually made available to such owner, lessor or mortgagee; and

bound by any amendment or modification of this Lease made without its consent; or

bound to return Tenant’s security deposit, if any, until such deposit has come into its actual possession and Tenant would be entitled to such security deposit pursuant to the terms of this Lease.

The provisions of this Section 9.2 shall enure to the benefit of any such owner, lessor or mortgagee, shall be self operative upon any such demand, and no further instrument shall be required to give effect to said provisions. Tenant, however, upon demand of any such owner, lessor or mortgagee, shall execute, at Tenant’s expense, from time to time, instruments, in recordable form, in confirmation of the foregoing provisions of this Section 9.2, satisfactory to any such owner, lessor or mortgagee, acknowledging such attornment and setting forth the terms and conditions of its tenancy. Nothing contained in this Section 9.2 shall be construed to impair any right otherwise exercisable by any such owner, lessor or mortgagee.

ARTICLE X.

GENERATOR

10.1.1.     Grant of Rights. Landlord grants Tenant the appurtenant, exclusive, and irrevocable (except upon the expiration or earlier termination of this Lease, or as otherwise provided in this Section) license at no additional charge (other than to the extent included in Operating Costs), but otherwise subject to the terms and conditions of this Lease, to use that portion of the Property in the location(s) set forth in Exhibit I attached hereto and incorporated herein by this reference (the “Generator Area(s)”) to, at Tenant’s sole cost and expense, operate, maintain, repair, and replace a generator at the 14 Crosby Building and/or the 18 Crosby Building, as applicable (each a “Generator”), which such Generator is approved by Landlord for Tenant’s own use, appurtenant to the Permitted Use, and any such Generator is to be installed by Tenant, at Tenant’s sole cost and expense, and in accordance with all terms and conditions contained herein, and in compliance with all Laws.

10.1.2.     Installation and Maintenance of Any Such Generator. Tenant shall install any such Generator, at Tenant’s sole cost and expense, at such times and in such manner as Landlord may reasonably designate and in accordance with all of the provisions of this Lease, and otherwise in accordance with all Laws. Prior to any such installation or modification of any such Generator, Tenant shall receive Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Tenant shall not install or operate any such Generator until it receives Landlord’s prior written approval of the plans for such work, which approval shall not be unreasonably withheld, conditioned, or delayed. Prior to Tenant commencing the installation of any such Generator, Tenant shall provide Landlord with copies of all required permits, licenses and authorizations that Tenant will obtain at its own expense and that Tenant will maintain at all times during the operation of any such Generator. Landlord may withhold approval if the installation or operation of any such Generator reasonably would be expected to damage the structural integrity of the 18 Crosby Building, 14 Crosby Building and/or the Property. Tenant shall maintain any such Generator in compliance with all applicable Laws, including any municipal noise ordinance. Tenant shall cooperate with Landlord as reasonably required to accommodate any building or grounds work during the Term. Tenant’s right to perform any such work in connection with any such Generator shall be limited to normal building hours by prior appointment with the property manager, except in the case of emergencies threatening life or personal property. Tenant, at its sole cost and expense, shall cause a qualified contractor to inspect the Generator Area(s) as frequently as consistent with applicable laws and best practices observed by other users of equipment of similar size, function, and manner of installation as any such Generator, but in no event less frequently than once per calendar month; shall correct any loose bolts, fittings or other appurtenances related to any such Generator and shall repair any damage to the areas surrounding the Generator Area(s) caused by the installation or operation of any such Generator or its appurtenances. Tenant shall pay Landlord following a written request therefor, with the next payment of rent, (i) all applicable taxes or governmental charges, fees, or impositions imposed on Landlord because of Tenant’s use of the Generator Area(s) and (ii) the amount of any increase in Landlord’s insurance premiums as a result of the installation of any such Generator. Any such Generator shall be fenced in or otherwise protected in accordance with best practices observed by other users of similarly-sized equipment with similar functions.

10.1.3.     Indemnification. Tenant agrees that the installation and operation of any such Generator shall be at its sole risk. Except to the extent due to the gross negligence or willful misconduct of Landlord, Tenant shall indemnify and defend Landlord and other Landlord indemnities against any liability, claim or cost, including reasonable attorneys’ fees, incurred in connection with the loss of life, personal injury, damage to property or business or any other loss or injury arising out of the installation, use, or operation of any such Generator by Tenant or its employees, agents, or contractors, including any liability arising out of Tenant’s violation of this Section. Except to the extent due to the gross negligence or willful misconduct of Landlord, Landlord assumes no responsibility for interference in the operation of any such Generator caused by other tenants’ equipment, or for interference in the operation of other tenants’ equipment caused by any such Generator, and Tenant hereby waives any claims against Landlord arising from such interference. The provisions of this paragraph shall survive the expiration or earlier termination of this Lease.

10.1.4.     Relocation of Any Such Generator. Based on Landlord’s good faith determination that such relocation is reasonably necessary, Landlord reserves the right to relocate any such Generator to comparably functional space by giving Tenant prior notice of such intention to relocate. If within thirty (30) days after receipt of such notice Tenant has not agreed with Landlord on the space to which any such Generator is to be relocated, the timing of such relocation, and the terms of such relocation, then Landlord shall have the right to make all such determinations in its reasonable judgment. In the event that any such relocation is required and Tenant has exercised the ROFO as set forth in Section 8.17 herein, then Tenant shall be solely responsible, at Tenant’s sole cost and expense, for the cost of moving any such Generator to such other space, taking such other steps necessary to ensure comparable functionality of the applicable Generator, and finishing such space to a condition comparable to the location of any such Generator immediately preceding such relocation; provided, however, that in the event that any such relocation is required and Tenant has not exercised the ROFO as set forth in Section 8.17 herein, then Landlord and Tenant shall share equally for the cost of moving any such Generator to such other space, taking such other steps necessary to ensure comparable functionality of the applicable Generator, and finishing such space to a condition comparable to the location of any such Generator immediately preceding such relocation.

10.1.5.     Ownership of Any Such Generator. During the Term of the Lease, any such Generator shall be treated as Tenant’s personal property for all purposes. Upon the expiration or earlier termination of the Lease, Tenant shall remove, at Tenant’s sole cost and expense, any such Generator, subject to the terms and conditions contained in this Section 10.1.4. Notwithstanding the foregoing, Landlord shall have the option, by giving Tenant prior written notice no less than sixty (60) days prior to the expiration or earlier termination of the Lease, to purchase any such Generator from Tenant, the purchase price of which shall be equal to the Generator’s then-current fair market value, depreciated on a straight line basis.

10.1.6.     Environmental Testing. Provided that Landlord has a reasonable basis to conduct any such environmental testing, Landlord may require environmental testing by a consultant and with a scope of work reasonably acceptable to Landlord to determine if there has been a release of oil or hazardous substances with respect to the use by Tenant of any such Generator. If the environmental report determines that an environmental condition exists in the vicinity of the Generator Area(s) involving oil or hazardous substances due to Tenant’s use of any such Generator, then Tenant shall further investigate and remediate the affected area and be responsible for complying with all applicable environmental laws in connection therewith. If Landlord reasonably determines that additional environmental testing is necessary to verify that the environmental condition has been fully remediated, then Tenant shall reimburse Landlord for the reasonable cost associated therewith. The provisions of this paragraph shall survive the expiration or earlier termination of the Lease.

ARTICLE XI.

11.1.        Subject to the terms and conditions set forth below and subject to (i) the rights of existing tenants in the applicable space to extend the term of their lease and/or (ii) the prior rights, if any, of other tenants or occupants in the Building, Office Park and/or other buildings owned by Landlord with respect to the applicable space, Tenant shall have a one-time "Office Park Right of First Offer" to lease the following spaces (each an “Office Park ROFO Space”), but excluding any such Office Park ROFO Space that is vacant as of the date hereof and for a period of one (1) year thereafter: (i) the approximately 19,771 rentable square feet of space located on the first (1^st) floor of the 14 Crosby Building; (ii) that certain premises currently occupied by Life Care Centers of America, Inc. located in the 14 Crosby Building; (iii) the approximately 4,000 rentable square feet of space occupied as a cross fit located in the 14 Crosby Building; (iv) that certain premises currently occupied by Altair Engineering Inc. located in the building located at 4 Crosby Drive, Bedford, Massachusetts; (v) that certain premises currently occupied by Ultragenyx Pharmaceutical Inc. located in the building located at 16 Crosby Drive, Bedford, Massachusetts; and (vi) that certain premises currently occupied by Multiplan, Inc. located in the building located at 16 Crosby Drive, Bedford, Massachusetts.

11.2.        If there shall be less than three (3) years remaining in the then current Term, then Tenant's Office Park Right of First Offer for any such Office Park ROFO Space shall be contingent upon Tenant effectively exercising its option, if any, to extend the Term pursuant to Section 8.15 above at the same time as it exercises such Office Park Right of First Offer, and the term of the Office Park ROFO Space shall be for the same Term as extended.

11.3.        Landlord will notify Tenant of its plans to market any such Office Park ROFO Space for lease to any unrelated third party. Landlord's notice shall specify the applicable Office park ROFO Space that it plans to market, Landlord's estimate of the fair market rent for such Office Park ROFO Space, the date of availability of such Office Park ROFO Space and all other material terms and conditions which will apply to such Office Park ROFO Space. Tenant will notify Landlord within ten (10) days of Landlord's notice if Tenant wishes to lease such Office Park ROFO Space from Landlord on the terms and conditions so specified. If Tenant notifies Landlord that it wishes to lease the Office Park ROFO Space, Landlord and Tenant shall execute an amendment to this Lease incorporating the Office Park ROFO Space into the entire Premises upon the terms contained in Landlord's notice within ten (10) days thereafter. If Tenant fails to notify Landlord within said ten (10) day period that Tenant intends to lease such Office Park ROFO Space, or fails to simultaneously exercise its option to extend, if necessary, or fails to execute a lease agreement for such Office park ROFO Space within ten (10) days of Tenant's notice of intent to Landlord, Tenant shall be deemed to have waived its rights with respect to the Office Park ROFO Space and Landlord shall be entitled to lease, at its sole discretion and without any further notice to Tenant, all or any portion of such Office Park ROFO Space to any third party or parties on such terms and conditions, including, without limitation, options to extend the term of such lease and/or expand the premises under such lease, and for such rent as Landlord determines, all in its sole discretion, and the Office Park Right of First Offer with respect to any such space shall be of no further force or effect.

11.4.        Notwithstanding any contrary provision of this Article XI or any other provision of this Lease, any Office Park Right of First Offer and any exercise by Tenant of any Office Park Right of First Offer shall be void and of no effect unless on the date Tenant notifies Landlord that it is exercising any such Office Park Right of First Offer and on the commencement date of the amendment for such Office Park ROFO Space (i) this Lease is in full force and effect and (ii) no Event of Default has occurred under this Lease and (iii) except with respect to (a) a Permitted Transfer or (b) a sublease (which does not fall under the definition of Permitted Transfer) of 5,000 rentable square feet or less of the entire Premises, Tenant shall not have assigned this Lease, and there shall not be any sublease or subleases in effect as of the commencement of the term of the Lease for any such Office Park ROFO Space as of the date of Landlord's notice of any such Office Park ROFO Space availability.
