Tenant shall, within thirty (30) days after such delivery, pay Tenant’s share to Landlord, as Additional Rent, less any estimated payments. If the estimated payments exceed Tenant’s share, then the excess shall be applied against the next installment(s) of Base Rent and Additional Rent payable by Tenant, except that, with respect to the reconciliation for the last year of the term of the Lease, Landlord shall, at the time that it delivers the Year End Statement for such year, reimburse Tenant for any overpayment by Tenant, to the extent that such overpayment exceeds any amounts then due from Tenant to Landlord.

-5-

and records for the one (1) year immediately preceding the year in question solely for the purpose of determining whether such errors were made in the preceding year. If Tenant’s review establishes any overpayment by Tenant, Landlord shall either, at Landlord’s option, credit such amount to Tenant’s next payment of Additional Rent, or refund such amounts within thirty (30) days after receipt of Tenant’s calculations; if Tenant’s review discloses any underpayment by Tenant, Tenant shall pay such amounts within thirty (30) days from the time it calculates, or receives the calculation of such amounts. If, after performing any such audit, it is determined that Landlord has overbilled Tenant by more than 5% for the year in question, Landlord shall reimburse Tenant for its reasonable out-of-pocket costs incurred in performing such audit. Such audits may be performed by Tenant’s certified public account or by Tenant’s internal auditors but in no event shall any such examiner be compensated on a percentage basis of any recovery from Landlord.

Tenant shall be responsible for Operating Costs) on the entire 145,527 square feet of the Premises commencing on the Rent Commencement Date.

At the time of signing of this Lease, such Tenant’s Proportionate Share is expected to be eighty-two and eight-tenths percent (82.8%), based on one hundred forty five thousand five hundred twenty seven (145,527) square feet divided by one hundred seventy five thousand seven hundred sixty three square feet (175,763) square feet, the rentable square footage of the Property.

Section 5 - Payment of Rent and Late Charges. Payments due under Sections 3 and 4 above shall be made at Landlord’s office at the address set forth in Section 37, or such other place as Landlord may designate in writing, on or before the first of each month.

In addition to the late charge described above, any Rent or other amounts owing hereunder which are not paid within ten (10) days following the due date shall bear interest from the date when due until paid at an annual interest rate equal to the prime rate, as stated under the column “Money Rates” in The Wall Street Journal, plus four (4%) percent (“Lease Interest Rate”); provided, however, in no event shall such annual interest rate exceed the highest annual interest rate permitted by applicable Law.

Fair Market Rent shall not take into account the value of any leasehold improvements made by Tenant to the extent that the same have been paid for by Tenant.

(C) Tenant may, on or after the date fifteen (15) months prior to the end of the then current term, request that Landlord provide Tenant with Landlord’s determination of Base Rent for the Extension Term in question, and Landlord shall provide Tenant with Landlord’s determination of said Base Rent in writing within fifteen (15) business days of Landlord’s receipt of such request. If Tenant does not agree with Landlord’s determination, then Tenant shall so advise Landlord of such disagreement in Tenant’s Exercise Notice. If Tenant does not make such request of Landlord prior to the time that Tenant gives Tenant’s Exercise Notice for the Extension Term in question, Landlord shall, within thirty (30) days after Landlord receives Tenant’s Exercise Notice, furnish Tenant in writing with notice of Landlord’s determination of the Base Rent for the Extension Term in question. In such event, if Tenant does not agree with Landlord’s determination of Base Rent, Tenant shall advise Landlord in writing (“Dispute

-7-

Notice”) of such agreement within twenty (20) days of its receipt of such determination, In either case, if the parties do not agree upon the Base Rent for the Extension Term in question, then the Fair Market Rent shall be determined by appraisal as follows, Tenant hereby agreeing that it shall have no right to submit any dispute as to Fair Market Rent to appraiser unless Tenant has previously exercised its option to extend the term of the Lease for the Extension Term in question. Each of the parties shall, within twenty (20) days after the giving of Tenant’s Exercise Notice or within twenty (20) days after Tenant gives the Dispute Notice, select an appraiser, each of whom shall have at least five (5) years of experience in appraising commercial properties in the greater Boston area, and the two appraisers shall together select a third appraiser similarly qualified. The three appraisers together shall attempt to agree on the current market rate of Base Rent for the Extension Term in question. Failing a unanimous decision, the Base Rent shall be determined by majority vote of the appraisers. Landlord and Tenant shall each pay the charges for the appraiser which it selects, and they shall share equally the charges for the third appraiser. Following the exercise by Tenant of its option to extend the term hereof, all references in this Lease to the term hereof, or expressions of similar import, shall be deemed to refer to the term as so extended. The decision and award of the appraiser(s) shall be final and conclusive on all parties.

Notwithstanding anything to the contrary herein contained, in the event that either party exercises the option set forth in Section 27(A) to terminate this Lease, then Tenant shall have the right to claim and recover for Covered Alterations (as defined below) as follows: (i) any claim payable separately to Tenant shall be payable only so long as such claim does not diminish the award available to Landlord and/or its mortgagee; and (ii) if there is a single award, then the award allocable to the Premises, after deduction of all reasonable costs, including without limitation, costs to restore, if applicable, and reasonable attorney’s fees, incurred by Landlord in establishing said claim and collecting said award, shall be allocated between Landlord’s (and its mortgagee’s) interest and Tenant’s interest as follows and in the following order: (1) first, the entire claim of any mortgagee shall be paid; (2) second, Landlord shall be reimbursed for the fair market value of its interest in Premises (less the amount of the principal of any mortgage paid to mortgagee pursuant to clause (1)); (3) third, Tenant shall be reimbursed for the unamortized portion of the cost of any alterations or improvements paid for solely by Tenant (“Covered Alterations”), amortized over the initial term of the Lease; and (4) the balance of the award, if any shall be paid to Landlord.

(C) Casualty.

(1) Landlord’s Restoration Obligation. Landlord shall, within sixty (60) days if the cost to repair is not more than $500,000.00 (“Minor Damage”), or seventy-five (75) days if the cost to repair is over $500,000.00 (“Major Damage”), after the Premises or the Building are

-21-

damaged by any fire or other casualty, deliver to Tenant a reasonable estimate (“Restoration Period Estimate”) from a reputable contractor, of the date by which the repair and restoration necessary as a result of such fire or other casualty can be substantially completed. Subject to the provisions of this Section 27(C), if the Premises or the Building shall be damaged by fire or other casualty, Landlord shall promptly and diligently, to the extent of insurance proceeds made available to Landlord specifically for such repair, and subject to reasonable delays for insurance adjustment, delays caused by Tenant, and other delays beyond Landlord’s reasonable control, restore the Premises and the Building to substantially the same condition as when possession was initially delivered to Tenant; provided, however, Landlord shall not be required to rebuild, restore, repair or replace alterations or improvements made by Tenant to the extent that the cost of the same exceeds the Tenant Improvement Allowance or other improvements, alterations and additions, inventory, fixtures, furniture, furnishings, equipment and other personal property of Tenant. If such fire or other casualty shall have damaged the Premises and the Building necessary to Tenant’s occupancy, Tenant shall be entitled to an equitable abatement of Base Rent and other charges payable by Tenant under the Lease continuing from the date of such casualty until such time as any restoration or repairs which Landlord is required to undertake are restored substantially completed.

(2) Tenant’s Right to Terminate. If, based upon the Restoration Period Estimate, the estimated date by which Landlord would substantially complete repairs and restoration will be later than the date that is six (6) months after the date of the Restoration Period Estimate, Tenant shall have the right, which shall be exercisable by written notice given by Tenant to Landlord to terminate this Lease, effective not more than ninety (90) days after the date of such notice from Tenant.

(3) Landlord’s Right to Terminate. Landlord may elect not to rebuild and/or restore the Premises and the Building, and instead terminate this Lease by notifying Tenant in wilting of such termination (“Landlord’s Termination Notice”) within the latest of: (x) forty-five (45) days after the date of discovery of the damage, or (y) thirty (30) days after the date of the Restoration Period Estimate (such latest date, the “Landlord’s Termination Date”) such notice to include a termination date giving Tenant ninety (90) days to vacate the Premises, but Landlord may so elect only if the Premises damaged by fire or other casualty or cause, if one or more of the following conditions are present:

(i) the damage is caused by a peril or cause which is not covered by Landlord’s insurance policies (and/or would not be covered by the policies Landlord is required to carry pursuant to this Lease) and, in Landlord’s reasonable judgment, the cost to repair the damage exceeds $1,500,000 (such amount, the “Uninsured Loss”), provided, however, if Tenant agrees to pay for the Uninsured Loss, and deposits such sum with Landlord’s mortgagee (or if there is no mortgagee, with a mutually acceptable escrow agent) within ten (10) business days after Tenant receives Landlord’s notice of termination, then Landlord shall not have the right to elect not to rebuild or restore and to terminate the Lease based on this subsection (i); or

(ii) the damage occurs during the last twenty-four (24) months of the Lease Term, provided, however, if the damage occurs during the last twenty-four (24) months of the Lease Term, and Tenant has an option to extend under Section 7 that has not yet been exercised, and Tenant exercises such option, by written notice given to Landlord within ten (10) business days after Tenant receives Landlord’s notice of termination, then

-22-

Landlord shall not have the right to elect not to rebuild or restore and to terminate the Lease based on this subsection (ii).

(4) Time for Repair. If neither Tenant nor Landlord elects to terminate this Lease pursuant to the termination rights set forth in Section 27(B) or 27(C) respectively (if applicable), then, Landlord shall substantially complete such repairs within: six (6) months for Major Damage, or four (4) months in the case of Minor Damage, or, in either case, such longer period as may be set forth in the Restoration Period Estimate (the applicable time period for substantial completion of such repairs and/or restoration is referred to herein as the “Repair Period”) after Landlord’s receipt of written notice from Tenant that it is waiving its right to terminate pursuant, subject to delays due to causes beyond Landlord’s reasonable control, not to exceed four (4) months for Major Damage and not to exceed forty-five (45) days for Minor Damage, and subject to delays caused by Tenant. If the repairs to be made by Landlord are not actually substantially completed within the applicable Repair Period, as extended for the period of time (“Excused Delay Period”) that Landlord is delayed as the result of causes beyond Landlord’s reasonable control (limited, as aforesaid), Tenant shall have the right to terminate this Lease by providing written notice to Landlord (the “Damage Termination Notice”), such termination to be effective on a date (the “Damage Termination Date”) set by Tenant in such Damage Termination Notice that is not more than one hundred and twenty (120) days after Landlord’s receipt of the Damage Termination Notice.

Section 28 - Repossession by Landlord. At the expiration of this Lease or upon the earlier termination of this Lease for any cause herein provided for, Tenant shall peaceably and quietly quit the Premises and deliver possession of the same to Landlord.

Section 29 - Mortgage Lien. Tenant agrees that this Lease and all rights of Tenant hereunder are and shall be subject and subordinate to the lien of (1) any mortgage constituting a lien of the Property, or any part thereof, at the date hereof, (2) the lien of any mortgage hereafter executed to a bank, trust company or other recognized lending institution to provide permanent financing or refinancing of the land and improvements containing the Premises, and (3) any renewal, modification, consolidation or extension of any mortgage referred to in clause (1) and (2). Tenant shall, upon demand at any time or times with at least ten (10) business days prior written notice, execute, acknowledge and deliver to Landlord without any expense to Tenant, any and all instruments that may be necessary or proper to subordinate this Lease and all rights of Tenant hereunder to the lien of a mortgage referred to in (2) or (3) of the preceding sentence. It shall be a condition to the subordination of the Lease in accordance with this Section 29, that Landlord deliver to Tenant a nondisturbance agreement from the holder of the mortgage in question, in form reasonably acceptable to Tenant.

Section 30 - Tax Incentive Financing. Landlord agrees to use reasonable efforts to support Tenant’s efforts to obtain Tax Incentive Financing.

Section 31 - Environmental Matters.

(a) Tenant represents and warrants that it shall not use the Premises for the Storage, Treatment or Disposal of Hazardous Wastes, except in full compliance with all applicable laws, regulations and requirements of Governmental Authorities (as hereinafter defined). For the purposes of this Lease, the terms Hazardous Waste, Storage, Treatment and Disposal are defined by cumulative reference to the following sources, as amended from time to time: (1) The

-23-

Resource Conservation and Recovery Act of 1976, 42 USC §6901 et seq (RCRA); (2) EPA Federal Regulations promulgated thereunder and codified in 40 C.F.R. Parts 260-265 and Parts 122-124; (3) Chapter 21C and 21E of the Massachusetts General Laws; and regulations promulgated thereunder by any agency or department of the Commonwealth of Massachusetts. Promptly, upon the request of Landlord, Tenant shall provide Landlord with a list of all Hazardous Materials generated, stored, treated, or used on the Premises. It shall be a condition to Landlord’s receipt of any such information that Landlord execute and deliver to Tenant a Nondisclosure Agreement in the form attached hereto as Exhibit J.

(b) As used in this Section, the term “Hazardous Material” shall mean any substance, water or material which has been determined by any state, federal or local government authority to be capable of posing a risk of injury to health, safety and property, including, but not limited to, all of those materials, wastes and substances designated as hazardous or toxic by the U.S. Environmental Protection Agency, the U.S. Department of Labor, the U.S. Department of Transportation, and/or any other governmental agency, federal, state, or local, now or hereafter authorized to regulate materials and substances in the environment (collectively “Governmental Authority(ies)”).

(c) Tenant agrees to take responsibility for any remedial action required by Government Authorities having jurisdiction regarding any Hazardous Material or Hazardous Waste owned, controlled, used or manufactured by Tenant, or for which Tenant is otherwise legally responsible. Tenant shall pay all costs in connection with any such investigation or remedial activity including, without limitation, all installation, operation, maintenance, testing, and monitoring costs, all power and utility costs and any and all pumping taxes or fees that may be applicable to Tenant’s activities. Tenant shall perform all such work in a good, safe and workmanlike manner, in compliance with all laws and regulations thereto, and shall diligently pursue any required investigation and remedial activity until Tenant is allowed to terminate these activities by those Government Authorities having jurisdiction.

(d) Tenant shall conduct any testing, monitoring, reporting and remedial activities in connection with the Premises in a good, safe and workmanlike manner and in compliance with all laws and regulations applicable thereto. Tenant shall promptly, upon written request of Landlord, from time to time, provide Landlord with copies of any testing results and reports that are generated in connection with Tenant’s activities and that are submitted to any Government Authority.

(e) Tenant shall indemnify, hold harmless, and defend Landlord, its officers, members, employees and agents (collectively “Indemnities”) against all claims, demands, losses, liabilities, costs and expenses, including reasonable attorneys’ fees, (collectively “Liabilities”) imposed upon or accruing against Indemnitees as actual and direct costs of investigatory or remedial action required by any Government Authority having jurisdiction or as damages to third persons for personal injury or property damage arising from the existence of Hazardous Material or Hazardous Waste referred to in subparagraph (c). Such Liabilities shall include, without limitation: (i) injury or death to any person, (ii) damage to any other property, (iii) the cost of any demolition and rebuilding of the improvements containing the Premises, repair, or remediation and the preparation of any closure or other activity required by any Governmental Authority, (iv) any lawsuit brought or threatened, good faith settlement reached, or governmental order relating to the presence, disposal, release or threatened release of any Hazardous Material or Hazardous Waste referred to in subparagraph (c), on, from or under the land and building

-24-

containing the Premises, and (v) the imposition of any liens on the land and building containing the Premises arising from Tenant’s activities on or about the Premises or from the existence of Hazardous Material or Hazardous Waste referred to in subparagraph (c).

(f) Tenant shall have no responsibility for Hazardous Waste or Hazardous Materials existing on the Premises on the date that Tenant first takes occupancy of the Premises, except that Tenant shall be responsible for any costs and expenses incurred by or assessed against Landlord which result from Tenant’s activities or from aggravation of such preexisting conditions during the tenancy of Tenant.

(g) Tenant shall use its best efforts (including payment of money) not to cause or suffer any lien to be recorded against the land and building containing the Premises as a consequence of, or in any way related to, the presence, remediation or disposal of Hazardous Material or Hazardous Waste in or about the Premises, including any mechanics’ liens and any so-called state, federal or local “superfund” lien relating to such matters.

(h) Notwithstanding anything herein to the contrary, Landlord warrants that, to the best of its knowledge, there are, as of the Execution Date of this Lease, no Hazardous Material or Hazardous Waste located in, on or under the Premises, the Building, or the Land. To the extent that any pre-existing Hazardous Materials or Hazardous Waste are discovered after the Execution Date of this Lease, Landlord agrees, at no cost to Tenant, to be responsible for removal of and remediation of any such Hazardous Materials or Hazardous Waste. Landlord agrees to provide Tenant with its Phase I report for Tenant review.

Section 32 - Americans With Disabilities Act. Upon delivery, the Premises, the Building and the Land will be in compliance with the American With Disabilities Act (ADA) and applicable State and City laws and ordinances. Any modifications required by said Act, or modifications necessitated by Tenant Improvement Work, shall be the responsibility of Tenant.

Section 33 - Default. The following shall be deemed to be “Events of Default” by Tenant: (i) Tenant fails to pay any installment of Base Rent or Additional Rent within seven (7) days after Tenant receives written notice from Landlord that the same is past due, or (ii) Tenant defaults in the performance or observance of any other covenant or condition in this Lease and such default remains unremedied for twenty (20) days after written notice thereof Tenant receives written notice from Landlord of such default, or such longer period of time as Tenant may reasonably require to cure such default so long as Tenant commences to cure such default within such twenty (20) day period and diligently prosecutes such cure to completion, or (iii) Tenant makes an assignment for the benefit of creditors, files a voluntary petition in bankruptcy, is adjudicated insolvent or bankrupt, petitions or applies to any tribunal for any receiver or any trustee of or for Tenant of any substantial part of its property, commences any proceeding relating to Tenant or any substantial part of its property under any reorganization, arrangement, readjustment of debt, dissolution or liquidation law or statute of any jurisdiction, whether now or hereafter in effect, or (iv) there is commenced against Tenant any such proceeding which remains undismissed for a period of ninety (90) days, or any order approving the petition in any such proceeding is entered, or Tenant by any act indicates its consent to, or acquiescence in any such proceeding or the appointment of any receiver of or trustee for Tenant of any substantial part of its property, or (v) suffers any such receivership or trusteeship to continue undischarged for a period of sixty (60) days, Upon the occurrence of any Event of Default, then in any of such events, Landlord may immediately or at any time thereafter and

-25-

without demand terminate this Lease by written notice to Tenant thereof or, without demand or notice enter upon the Premises or any part thereof in the name of the whole and repossess the same as of Landlord’s former estate and expel Tenant and those claiming through or under Tenant and remove their effects in any manner permitted law, without being deemed guilty of any manner of trespass and without prejudice to any remedies which might otherwise be used for arrears of rent or preceding breach of covenant. Upon such termination notice or entry this Lease shall terminate, and Tenant covenants that, in case of such termination by reason of the default of Tenant, Tenant shall remain and continue liable to Landlord in an amount equal to the total Base Rent reserved for the balance of the term hereof plus all Additional Rent reserved for the balance of the term hereof less the net amounts (after deducting the expenses, incurred by Landlord in good faith, of repair, renovation or demolition and reasonable attorneys fees and leasing commissions, provided that such expenses shall be amortized over the term of the replacement lease with respect to which they were incurred) which Landlord realizes from the reletting of the Premises. As used in this Section, the term “Additional Rent” means the obligations of Tenant under Section 4 and the value of all considerations other than rent agreed to be paid or performed by Tenant hereunder, including, without limiting the generality of the foregoing, taxes, assessments and insurance premiums. Landlord hereby agrees to use reasonable efforts to mitigate any damages which it incurs in connection with any default by Tenant under this Lease. Landlord shall have the right, consistent with Landlord’s obligation to use reasonable efforts to mitigate its damages, as aforesaid, from time to time to relet the Premises upon such terms as it may deem fit, and if a sufficient sum shall not be thus realized to yield the net rent required under this Lease, Tenant agrees to satisfy and pay all deficiencies as they may become due during each month of the remaining term of this Lease. Nothing herein contained shall be deemed to require Landlord to await the date whereon this Lease, or the term hereof, would have expired had there been no default by Tenant, or no such termination or cancellation. Tenant expressly waives service of any notice of intention to reenter and waives any and all right to recover or regain possession of the Premises, or to reinstate or redeem this Lease as may be permitted or provided for by or under any statute or law now or hereafter in force and effect. The rights and remedies given to each party to this Lease are distinct, separate and cumulative remedies, and no one of them, whether or not exercised by such party, shall be deemed to be in exclusion of any of the others herein or by law or equity provided. Nothing contained in this Section shall limit or prejudice the right of Landlord to prove and obtain, in proceedings involving the bankruptcy or insolvency of, or a composition with creditors by, Tenant the maximum allowed by any statute or rule of law at the time in effect.

Section 34 - Legal Fees. In the event of any litigation between the parties, the losing party shall reimburse the prevailing party for its reasonable attorney’s fees and court costs; provided, however, in any instance in which Landlord brings an action against Tenant for nonpayment of Base Rent or Additional Rent or brings an action for eviction, Tenant shall reimburse Landlord for its reasonable attorney’s fees, expenses and costs even if the action is dismissed by Landlord; provided, however, that if Landlord receives an adverse decision in such action, then Landlord shall not be reimbursed for its fees.

Section 35 - Access to Premises.

(A) Subject to the provisions of this Section 35, Landlord or its representatives shall have free access to the Premises at reasonable intervals during normal business hours for the purpose of inspection, or for the purpose of showing the Premises to prospective purchasers or Tenants, or for the purpose of making repairs which Landlord is obligated to make hereunder or

-26-

which Tenant is obligated to make hereunder but has failed or refused to make. The Landlord shall have access to the Premises at any time the Landlord deems, in good faith, that an emergency situation exists. The preceding sentence does not impose upon Landlord any obligation to make repairs. Landlord also reserves the right to alter, change, close or limit access to any portion of the common areas on the Property or to designate portions of such common areas for use by a single tenant of the Property; provided that: (i) Landlord may not exercise such rights in contravention of any of the provisions of this Lease, and (ii) in no event shall the exercise of Landlord’s rights under this Section 35 materially interfere with Tenant’s use of, or access to the Premises, or Tenant’s parking rights.

(B) Notwithstanding anything to the contrary in the Lease contained:

(1) Except in emergency situations, Landlord shall give Tenant reasonable notice prior to exercising any right which it has to enter the Premises.

(2) In exercising any right which Landlord has to enter the Premises, Landlord shall use reasonable efforts to minimize any interference with Tenant’s use of the Premises.

(3) Except in emergency situations, Tenant shall have the right to have a representative accompany Landlord and its representatives and contractors during any entry into the Premises,

(4) Landlord agrees that, except in case of emergencies threatening injuries to persons or damage to property, Tenant may require any Landlord or any person entering the Premises under Landlord’s authority to execute a confidentiality agreement in the form attached hereto as Exhibit J prior to its entry into the Premises to protect against the disclosure of Tenant’s proprietary information.

(5) Tenant shall have the right to designate secure areas in the Premises which Landlord shall have no right to enter, except in an emergency.

Section 36 - Holding Over. Except for written mutual consent by Landlord and Tenant, any holding over by Tenant after the expiration of the term of this Lease shall be treated as a daily tenancy at sufferance at a rate equal to one hundred fifty percent hundred percent (150%) of the Base Rent and Additional Rent herein provided (prorated on a daily basis) and shall otherwise be on the terms and conditions set forth in this Lease as far as applicable. Tenant shall not be responsible for any damages to Landlord based upon any hold over in the Premises after the expiration of the term of the Lease unless hold over continues for a period of at least sixty (60) days.

Section 37 - Notice. Any written notice, request or demand required or permitted by this Lease shall, until either party shall notify the other in writing of a different address, be properly given if sent by certified or registered first class mail, postage prepaid, return receipt requested, or by prepaid overnight delivery service, telecopy, or telegram (with messenger delivery specified) and shall be deemed given on the day that such writing is received. A facsimile/telecopy notice shall be deemed delivered as long as the sender receives a facsimile/telecopy receipt and concurrently sends a “hard copy” addressed (if notice is given by mail) as follows:

-28-

Section 44 - Force Majeure. With respect to any services, including, without limitation, electric current or water to be furnished by Landlord to Tenant, or obligations to be performed by either party hereunder, neither party shall in any event be liable for failure to furnish or perform the same when (and the date for performance of the same shall be postponed so long as such party is) prevented from doing so by strike, lockout, breakdown, accident, order or regulation of or by any governmental authority, or failure of supply, or inability by the exercise of reasonable diligence to obtain supplies, parts or employees necessary to furnish such services, or perform such obligations or because of war or other emergency, or for any cause beyond either party’s reasonable control, or for any cause due to any act or neglect of the other party or the servants, agents, employees, licensees, invitees of such other party; provided, however, that: (i) nothing herein shall extend or delay any termination, abatement or self-help right which Tenant has under this Lease which is based upon a time certain, (ii) financial inability shall in no event be deemed to be a cause beyond either party’s control, and (iii) in any case where a party is unable to perform based upon a cause beyond its control, such party shall use diligent efforts to perform such obligation, notwithstanding such cause beyond its control. Force majeure shall in no event excuse late or non-payment of Base Rent or other charges due to Landlord.

Section 45 - Invalidity of Particular Provisions. If any term or provisions of this Lease or the application thereof to any person or circumstance shall, to any extent, be held to be invalid or unenforceable, the remainder of this Lease, or the application of such terms or provisions to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby, and each term and provision of this Lease shall be valid and enforceable to the fullest extent permitted by law.
