The “Office Section” means the seven (7) levels of office area in four so-called “Towers” (denoted, respectively, as “One Xxxxxx Place”, “Two Xxxxxx Place”, “Three Xxxxxx Place” and “Four Xxxxxx Place” or as “Tower 1”, “Tower II”, “Tower Ill” and “Tower IV”, respectively), containing approximately 867,564 square feet of rentable floor area constituting a portion of the building (the “Building”) located at the aforesaid address. The Building also contains retail shopping, restaurant, parking and other facilities, which are not included within the Office Section. The Building does not, however, include the hotel or residential portions of the Property or the pedestrian bridges.

The provisions set forth in this lease are the result of a negotiation in which the parties were represented by counsel experienced in lease transactions of office space in the Commonwealth of Massachusetts. Each of the provisions was negotiated in view of the entire transaction including the type and location of the property, the rental, the term and the respective rights, obligations and remedies of the Landlord and Tenant. As a result, the rights, obligations and remedies which have been agreed to herein are, as negotiated, a part of the transaction as a whole and neither party intends that the absence of any particular remedy being specified for a particular action or lack of action by the other party imply that the parties intended any remedy not so specified. Without limiting the generality of the foregoing, in no event shall Tenant have the right to terminate or cancel this lease as a result of any default by Landlord or breach by Landlord of its covenants or any warranties or promises hereunder, except in the case of a wrongful eviction of Tenant from the demised premises (constructive or actual) by Landlord or as otherwise specifically set forth herein. In consideration of the covenants herein contained, Landlord and Tenant hereby agree as follows:

If the Rent Commencement Date for any portion of the Premises is other than on the first day of a month or the Term ends other than on the last day of the month, the Base Rent for such month shall be prorated. The prorated Base Rent for the portion of the month in which the Rent Commencement Date occurs shall be paid on the Rent Commencement Date.

ARTICLE 5.
ADDITIONAL RENT

5.01 Obligation as to Additional Rent. In addition to paying the Base Rent specified in ARTICLE 4 hereof, Tenant shall, commencing on the Rent Commencement Date and for the duration of the Term, pay as “Additional Rent” the amounts determined pursuant to Sections 5.03 and 5.04 of this ARTICLE 5. The Base Rent and the Additional Rent are sometimes collectively referred to in this Lease as the “Rent”. All amounts due under this ARTICLE as Additional Rent shall be payable for the same periods and in the same manner, time and place as the Base Rent and in the same currency, without any abatement, counterclaim, set-off or deduction whatsoever, except as expressly set forth herein. Without limitation on other obligations of Tenant that shall survive the expiration of the Term, the obligations of Tenant to pay the Additional Rent provided for in this ARTICLE 5 shall survive the expiration of the Term for a period of eighteen (18) months. For any partial Calendar Year following the Rent Commencement Date, Tenant shall be obligated to pay only a pro rata share of the Additional Rent, based on the number of days of the Term falling within such Calendar Year.

5.02 Definitions. As used in this ARTICLE 5, the terms:

(i) “Calendar Year” shall mean each calendar year in which any part of the Term falls, through and including the year in which the Term expires.

(ii) “Tenant’s Proportionate Tax Share” shall mean the percentage specified in ARTICLE 1 hereof, being the percentage calculated by dividing the rentable area contained in the Premises by 824,186 (being 95% of the rentable square foot area of the Office Section).

(iii) “Tenant’s Proportionate Expense Share” shall mean the percentage specified in ARTICLE 1 hereof, being the percentage calculated by dividing the rentable area contained in the Premises by 824,186 (being 95% of the rentable square foot area of the Office Section).

(iv) “Taxes” shall mean all real estate taxes and assessments, special or otherwise, levied or assessed upon or with respect to the Property or any part thereof including without limitation Common Areas as such taxes and assessments are reasonably determined by Landlord to be for the benefit of the Office Section and ad valorem taxes for any personal property of Landlord to the extent used in connection with the Office Section. For purposes of clarity, it is understood that there is one real estate tax xxxx for the Property and that Landlord allocates to the Office Section real estate taxes and assessments on the entire Property based upon the reasonable determination of Landlord. Should the Commonwealth of Massachusetts, or any political subdivision thereof, or any other governmental authority having jurisdiction over the Building, (a) impose a tax, assessment, charge or fee, which Landlord shall be required to pay, by way of substitution for or as a supplement to such real estate taxes and ad valorem personal property taxes, or (b) impose an income or franchise tax or a tax on rents in substitution for or as a supplement to a tax levied against the Property or any part thereof and/or the personal property used by Landlord in connection with the Property or any part thereof, all such taxes, assessments, fees or charges (hereinafter defined as “in lieu of taxes”) shall be deemed to constitute Taxes hereunder. Taxes shall also include, in the year paid, all fees and costs reasonably incurred by Landlord in seeking to obtain a reduction of, or a limit on the increase in, any Taxes, regardless of whether any reduction or limitation is obtained. Taxes shall not include any inheritance, estate, succession, transfer, gift, franchise, corporate excise taxes, transfer taxes, or net income or capital stock tax. If less than 95% of the Office Section is occupied during all or a portion of the Tax Base Year or any Adjustment Year, Landlord shall make an appropriate adjustment in Taxes for such year by adjusting the amount deemed to be Taxes for such Calendar Year so that Tenant’s responsibility for Taxes shall be an amount equal to the amount it would have paid on account of Taxes had the Office Section been 95% occupied. In computing the Adjustment Amount under Section 5.03, any refund of Taxes received by Landlord in the period during which Taxes is being computed and which is available to benefit Tenant as described in this ARTICLE 5, shall, net of the cost of obtaining such refund (to the extent costs were not previously included in Taxes or Operating Expenses), reduce Taxes to which Section 5.03 is applicable; and if Tenant expands into space formerly occupied by other tenants, which expansion space becomes subject to this Lease, Tenant shall not be entitled to any refund or credit in connection with a refund or abatement of Taxes for periods prior to the commencement date for Tenant’s lease of such expansion space. All references to Taxes “for” a particular Calendar Year shall be deemed to refer to Taxes due and payable during such Calendar Year without regard to when such Taxes are assessed or levied.

(v) “Operating Expenses” mean all expenses, costs and disbursements of every kind and nature, other than Taxes, paid or incurred by Landlord in operating, managing, repairing and maintaining the Property and its appurtenances as such expenses, costs and disbursements are reasonably allocated on a fair and equitable basis

to the Office Section by the Landlord in its sole reasonable judgment, or as the same are incurred directly in the operation of the Office Section. Operating Expenses shall include, without limitation: premiums for fire, casualty, liability and such other insurance as Landlord may from time to time maintain; security expenses; compensation and all fringe benefits, workmen’s compensation insurance premiums and payroll taxes paid by Landlord to, for or with respect to all persons engaged in operating, maintaining, or cleaning the Property (equitably apportioned, if such personnel serve the Property and other properties); steam, water, sewer, stormwater, electric, gas, telephone, and other utility charges to the Building not billed directly to tenants by Landlord or the utility; expenses incurred in connection with the central plant furnishing heating, ventilating and air conditioning to the Office Section (and to the Building and the Property where and to the extent the expenses of the Building and the Property are otherwise allocable to the Office Section), which expenses may include a reasonable fee paid to the independent operator of such central plant; costs of lighting, ventilating, (including maintaining and repairing ventilating fans and fan rooms) making routine repairs to and maintenance of underground roadways (and the access ramps servicing such roadways) and railroad platforms and railroad rights of way (including track); costs of repairing and maintaining fire protection systems relating to the underground roadways, access ramps, railroad platforms and railroad rights of way; costs of building and cleaning supplies and equipment (including rental); cost of maintenance, cleaning and repairs; cost of snow plowing or removal, or both, and care of interior and exterior landscaping; payments to independent contractors under contracts for cleaning, operating, management, maintenance and repair (which payments may be to affiliates of Landlord so long as not more than the market rate for such services is included in determining Tenant’s share of Operating Expenses); all other expenses paid in connection with cleaning, operating, management, maintenance and repair, and the amortized cost of capital expenditures (provided that replacement parts or components which are essentially in the nature of regular maintenance replacements even though classified for accounting purposes as capital and which are installed in the ordinary course of business shall not be deemed capital for these purposes and shall not therefore be capital expenditures for purposes of this Lease) which are: (a) in good faith based upon engineering estimates intended to (I) stabilize or reduce, over the portion of the useful life of such improvements or equipment within the then Term, operating expense costs that would otherwise be incurred or (II) improve the operating efficiency of the Property; or (b) required to comply with any Laws that are enacted, or first become effective, after the date of this Lease. The amount included in any Calendar Year with respect to such capital expenditure shall be the total expenditure amortized by Landlord over the useful life thereof determined in accordance with generally accepted accounting principles or, in the case of those items described in clause (a)(I) or clause (a)(II) above, the lesser of the useful life of such items and the Payback Period (defined below). The amortized cost of a capital expenditure may, at Landlord’s option, include actual rate paid by Landlord to finance the capital expenditure or imputed interest at the rate that Landlord is charged for moneys then borrowed by Landlord or by an affiliate that makes such funds available to Landlord for operations. “Payback Period” means the reasonably estimated period of time that it takes for the cost savings resulting from a capital expenditure to equal the total capital expenditure.

Operating Expenses shall not, however, include the following:

(a) costs of any alterations or special services rendered to individual tenants (including Tenant), for which a special, separate charge shall be made or which is not furnished generally to all office tenants of the Building;

(m) any penalties or damages that Landlord pays to Tenant under this Lease or to other tenants in the Building under their respective leases;

(u) costs of so-called lease or credit enhancement insurance or similar insurance products, whether or not the same is required by any mortgagee of the Property, which are obtained for the purpose of obtaining financing or similar credit benefits that inure to the owner or mortgagee of the Property.

If less than 95% of the Office Section’s rentable area shall have been occupied by tenant(s) at any time during any Calendar Year (including the Operating Expense Base Year), for purposes of determining the Adjustment Amount (as hereinafter defined) and the Operating Expense in the Base Year, each component of Operating Expenses for such Calendar Year allocated to the Office Section that varies with fluctuations in occupancy shall be deemed to be an amount equal to the like component which would reasonably be expected to have been incurred had such occupancy been 95% throughout such Calendar Year (including the Operating Expense Base Year, as applicable), so that the amount Tenant actually pays on account of Operating Expenses paid or incurred by Landlord reflects the amount Tenant would have paid if

the Office Section would have been 95% occupied during such period. If any item of Operating Expenses, though paid or incurred in one calendar year, relates to more than one Calendar Year, at the option of Landlord such item may be proportionately allocated among such related calendar years.

5.03 Expense & Tax Adjustment. Tenant shall pay to Landlord or Landlord’s agent as Additional Rent, a sum (“Adjustment Amount”) equal to the sum of (i) Tenant’s Proportionate Expense Share multiplied by the amount by which (a) Operating Expenses incurred in each Calendar Year exceeds (b) Base Year Operating Expenses plus (ii) Tenant’s Proportionate Tax Share multiplied by the amount by which (a) Taxes payable with respect to each Calendar Year exceeds (b) Base Year Taxes. The Adjustment Amount with respect to each Calendar Year shall be paid in monthly installments, in an amount reasonably estimated from time to time by Landlord and communicated by written notice to Tenant, which estimate may be revised to reflect increases in Taxes and Operating Expense adjustments. Landlord shall cause to be kept books and records showing Operating Expenses in accordance with an appropriate system of accounts and accounting practices consistently maintained for a period of at least two (2) years following the conclusion of each Calendar Year during the Term. Following the close of each Calendar Year, Landlord shall cause the amount of the Adjustment Amount for such Calendar Year to be computed based on Operating Expenses and Taxes for such Calendar Year and Landlord shall deliver to Tenant a statement of such amount and within thirty (30) days after receipt of such statement, Tenant shall pay any deficiency to Landlord as shown by such statement, as the same may have been adjusted by reason of such review. If the total of the estimated monthly installments paid by Tenant during any Calendar Year exceed the actual Adjustment Amount due from Tenant for such Calendar Year, at Landlord’s option such excess shall be either credited against payments next due hereunder or refunded by Landlord provided Tenant is not then in default hereunder with respect to any monetary obligation or in default beyond applicable notice and cure periods with respect to any other obligations. Delay in computation of the Adjustment Amount or a delay in the delivery of a statement of such amount shall not be deemed a default hereunder or a waiver of Landlord’s right to collect the Adjustment Amount hereunder; provided, however, Landlord’s failure to deliver such computation and statement within eighteen (18) months after the end of the applicable Calendar Year shall be deemed a waiver of Landlord’s right to collect any amount in addition to the amounts theretofore collected with respect to such applicable Calendar Year on account of Operating Expenses and Taxes (but such failure or delay in delivery shall not entitle Tenant to a refund of estimated amounts collected with respect to Operating Expenses and Taxes with respect to such applicable Calendar Year). The provisions of this Section 5.03 shall survive the expiration or earlier termination of this Lease.

5.04 Adjustment for Services not Rendered by Landlord. Tenant acknowledges that if Landlord is not furnishing any particular work or service the cost of which, if performed by Landlord, would be included in Operating Expenses, to any tenant who has undertaken to perform such work or service in lieu of the performance thereof by Landlord, and, as a result, Operating Expenses are reduced, Operating Expenses shall be deemed for the purpose of determining the Adjustment Amount to be increased by an amount equal to the additional Operating Expenses which would reasonably have been incurred during such period by Landlord if it had at its own expense furnished such work or service to such tenant. Furthermore, to the extent Landlord incurs any category or item contained within Operating Expenses that should

have been but was not included in the Base Year, then the Base Year Operating Expenses shall be increased by the amount which should have been included in the Base Year Operating Expenses.

5.05 Audit Rights. Tenant may, within one hundred eighty (180) days after receiving Landlord’s statement of Operating Expenses or Taxes, give Landlord written notice (“Review Notice”) that Tenant intends to review Landlord’s records of the Operating Expenses or Taxes for that calendar year and, if Tenant so chooses, the Calendar Year immediately preceding and/or the Operating Expense Base Year and Tax Base Year. Within a reasonable time after receipt of the Review Notice, Landlord shall make all pertinent records available for inspection by electronic files or in hard copy (which hard copies shall be provided at the Building and may, at Tenant’s expense, be copied). Such records shall set forth in reasonable detail the Operating Expenses or Taxes and shall include reasonable backup necessary for Tenant to conduct its review, including the records for the previous calendar year or base year for comparison. Within one hundred eighty (180) days after the records are made available to Tenant, Tenant shall have the right to give Landlord written notice (an “Objection Notice”) stating in reasonable detail any objection to Landlord’s statement of Operating Expenses or Taxes for the years under review. Tenant shall be deemed to have approved Landlord’s statement of Expenses or Taxes and shall be barred from raising any claims regarding the Operating Expenses or Taxes for that year if Tenant fails to give Landlord an Objection Notice within the 180 day period following the receipt of the statement for the next succeeding Calendar Year or fails to provide Landlord with a Review Notice within the applicable 180 day period described above. If Tenant provides Landlord with a timely Objection Notice, Landlord and Tenant shall work together in good faith to resolve any issues raised in Tenant’s Objection Notice. In the event Landlord and Tenant are unable to reach a mutual determination of the issues, Tenant shall have the right to have professional auditors conduct a review of Landlord’s books and records relating to Operating Expenses or Taxes incurred during the period. Such professional auditors may not, however, be engaged on a contingent fee basis. Such an audit may occur not more often than once in a year; shall be conducted within twelve (12) months (plus any period for which Landlord defers the audit as provided in this sentence) of receipt of a statement of the statement of Operating Expenses and Taxes (and the other documentation to which Tenant is entitled as set forth above) for the period being audited; shall be conducted during regular business hours of Landlord’s property manager at its office in the Boston, Massachusetts metropolitan area; provided, however, so long as Simon Property Group, Inc. or an affiliate is the property manager of the Building and the Building is owned by an entity in which an affiliate of Simon Property Group has an economic interest, such audit must be conducted in the Indianapolis, Indiana office of Landlord. Such audit shall occur on the date requested by Tenant which shall be on not less than fifteen (15) business days’ notice from Tenant to Landlord and may be deferred by Landlord, by notice to Tenant given at least ten (10) business days before the date proposed by Tenant, for up to one (1) month to a date convenient to Landlord’s property manager and Tenant. Landlord shall be provided with a copy of such third-party audit. If Landlord and Tenant determine without a third party audit, or if such audit demonstrates, that Operating Expenses or Taxes for the calendar year are less than reported, Landlord shall provide Tenant with a credit against the next installment of Rent in the amount of the overpayment by Tenant. Likewise, if Landlord and Tenant determine that Operating Expenses or Taxes for the calendar year are greater than reported, or if the audit so demonstrates, Tenant shall pay Landlord the amount of any underpayment within thirty (30) days. In addition, if as a result of an audit, Operating Expenses

or Taxes are found to be overstated by more than five percent (5%), Landlord shall pay to Tenant, Tenant’s reasonable cost of conducting such audit, not to exceed $15,000.00, plus, if applicable, reasonable travel costs to Indianapolis for necessary auditing staff. The records obtained by Tenant shall be treated as confidential. In no event shall Tenant be permitted to examine Landlord’s records or to dispute any statement of Operating Expenses or Taxes unless Tenant has paid and continues to pay during the period of the audit all Rent when due.

5.06 Billing for Electricity.

(i) Lack of Separate Metering. The Premises are not separately metered for electricity and, accordingly, Tenant shall pay Landlord as further Additional Rent, in monthly installments at the time prescribed for monthly installments, the electrical charge computed by Landlord based on a check meter installed at Landlord’s sole cost and expense and the applicable rates and surcharges of the electrical utility serving the Premises (without any surcharges by Landlord).

(ii) Separate Metering. In the event that Landlord in its sole discretion subsequently makes arrangements with the utility company supplying electricity to the Premises for separate metering and billing, Tenant shall pay (as hereinafter described) for the use of all electrical service to the Premises (other than the electrical service necessary for Landlord to fulfill its obligation to provide heating and air conditioning as provided in subsection 8.01(i) hereof). In such event, Tenant shall be billed directly by such utility company and Tenant agrees to pay each xxxx promptly in accordance with its terms. In the event that for any reason Tenant cannot be billed directly, Landlord shall forward each xxxx received by it with respect to the Premises to Tenant and Tenant shall pay such xxxx promptly in accordance with its terms.

ARTICLE 6.
USE OF PREMISES

Tenant shall use and occupy the Premises in accordance with law; and solely for the Permitted Uses specified in ARTICLE 1 hereof and for no other purpose or purposes. For purposes of clarity, it is understood that an office use shall include the right of the Tenant to conduct an on-line retail operation; provided, however, Tenant shall have no right to conduct an in-person retail operation on the Premises.

ARTICLE 7.
CONDITION OF PREMISES; LANDLORD’S WORK

7.01 Condition of Premises. The Premises are demised to Tenant and Tenant accepts the same “as-is”, except that (a) if, not later than sixty (60) days following the date of this Lease, Tenant notifies Landlord that the Initial Premises or a portion thereof (clearly designated in such notice to Landlord) are to be delivered in shell condition (but absent such notice Landlord will not otherwise be obligated to perform the Shell Work, time being of the essence of such notice), the Landlord shall, with respect to such designated portion(s) of the Premises, perform the Shell Work described in Exhibit B-1 at Landlord’s sole cost and expense prior to September 1, 2013, and all other work necessary to prepare the Initial Premises for Tenant’s occupancy shall be

performed at Tenant’s sole cost and expense, in accordance with the applicable provisions of this Lease and (b) as to space added to the Premises pursuant to Section 42.01, if Tenant elects as provided therein, that some or all of the space so added shall be delivered in shell condition (but absent such notice Landlord will not otherwise be obligated to perform the Shell Work, time being of the essence of such notice), the Landlord shall, with respect to such designated portion(s) of the Premises, perform the Shell Work described in Exhibit B-1 at Landlord’s sole cost and expense prior to the date which is ninety (90) days following the date on which the additional space would be delivered under Section 42.01 but for the Tenant election that the same be delivered in shell condition, and all other work necessary to prepare the space so added under Section 42.01 for Tenant’s occupancy shall be performed at Tenant’s sole cost and expense, in accordance with the applicable provisions of this Lease. Tenant’s taking possession of any portion of the Premises shall be conclusive evidence that such portion of the Premises was in good order and satisfactory condition when Tenant took possession, and except for latent defects not readily apparent from a careful inspection of the Premises without cutting into or otherwise disturbing walls, floors or ceilings and punchlist items of which Tenant has delivered notice to Landlord, excluding items of damage caused by Tenant or its agents, independent contractors or suppliers (subject to the provisions of Section 3.01 of this Lease). No promise of Landlord to alter, remodel or improve the Property and no representation by Landlord or its agents respecting the condition of the Property has been made to Tenant or relied upon by Tenant other than as may be contained in this Lease or in any written amendment hereto signed by Landlord and Tenant.

7.02 Building Renovations. Subject to Landlord obtaining Boston Redevelopment Authority and City of Boston approvals, as well as approvals and/or relocation agreements of tenants affected by proposed construction, including without limitation Barneys New York, Banana Republic, Sovereign Bank, BCBG and Xxxxx Xxxxxx, Landlord shall, at Landlord’s sole cost and expense, complete the planned renovations to the Property (not limited to new office lobby on retail level, upgraded sky lobby, conference center and roof deck). Landlord’s intention is that such approvals will be diligently pursued so as to permit completion of such renovations no later than the Commencement Date.

7.03 Landlord’s Work. Prior to the Commencement Date, Landlord shall, at its sole cost and expense substantially complete, in a good and workmanlike manner and in accordance with Legal Requirements, Landlord’s Work as set forth in Exhibit B-2.

ARTICLE 8.
SERVICES

8.01 List of Services. Landlord shall provide the following services, the costs of which are included within Operating Expenses, on all days during the Term, except Sundays and holidays, unless otherwise stated, and subject to all governmental rules, regulations and guidelines applicable thereto:

(i) HVAC. Heating and air conditioning in the Premises during the normal heating and air conditioning seasons, from Monday through Friday, during the period from 8 a.m. to 6 p.m. and on Saturday during the period from 8 a.m. to 1 p.m., satisfying the standards set forth in Schedule 8.01 attached hereto. Tenant will pay for all heating

and air conditioning requested and furnished prior to or following such hours at rates to be established from time to time by Landlord and intended by Landlord to reflect, when set, Landlord’s good faith estimate of its cost to deliver such after-hours heating and air conditioning. Requests for any additional services shall be in writing and delivered to Landlord’s property manager not later than 2 p.m. of the previous day.

(ii) Electric. Adequate electrical wiring and facilities for standard building lighting fixtures provided by Landlord and for Tenant’s incidental uses (it being understood that Tenant is to bear the cost of replacement of all lamps, tubes, ballasts and starters for lighting fixtures in the Premises); provided that (a) the connected electrical load for lighting and incidental use equipment does not exceed an average of six (6) xxxxx per rentable square foot of the Premises; (b) the electricity so furnished for incidental uses will be at 277 volts (and may be stepped down at Tenant’s expense in accordance with Tenant’s requirements) and no electrical circuit for the supply of such incidental use will have a current capacity exceeding 20 amperes; and (c) such electricity will be used only for equipment and accessories normal to office usage, including without limitation a server room. If Tenant’s requirements for such electricity (including without limitation supplemental cooling requirements by reason of such uses) are in excess of those set forth in the preceding sentence, Landlord reserves the right to require Tenant to install the conduit, wiring and other equipment necessary to supply electricity for such excess use requirements at Tenant’s expense.

(iii) Water. Water at temperatures and otherwise as supplied by the City of Boston or other water provider for drinking, lavatory and toilet purposes and to water which Tenant can use to supply its condenser units for supplemental heating, ventilation and air-conditioning as provided in Section 8.3(c) below (but Landlord shall not have an obligation to provide so-called condenser water).

8.02 Landlord Repairs and Maintenance. Landlord shall operate the Building in a good and quality manner at all times and shall maintain and repair the Building components described in this subsection 8.02 in good condition and repair, consistent with standards for similar office buildings in downtown Boston, Massachusetts which have services, systems and facilities comparable to the Building. Landlord agrees to keep neat and clean and in good order, condition and repair, and in compliance with all Legal Requirements, the roof, public and common areas, plazas, exterior walls (including exterior glass), foundation, footings, structure and structural elements of the Building and the plumbing, mechanical, electrical, fire safety, sprinkler, heating, ventilation, air conditioning, elevator and telecommunications systems, ducts, pipes and conduits serving the Premises and the other portions of the Building, but nothing herein shall require the Landlord to repair or maintain any portion thereof that is for the exclusive use of Tenant or any tenant or occupant of the Building. All costs incurred by Landlord in the performance of its obligations under this Section 8.02 shall be included in Operating Expenses subject to and in accordance with ARTICLE 5. If (a) Landlord fails to make repairs or replacements which Landlord has undertaken to make under the provisions of this subsection 8.02 or elsewhere in this Lease and (b) by reason of such failure, there is an imminent threat in the Premises to persons or property or Tenant is prevented from conducting its business operations in the Premises, Tenant may elect to take reasonable action within the Premises (and without affecting structure or systems outside of the Premises) solely to remedy the condition threatening such persons or property or Tenant’s business operations. Tenant shall endeavor to give Landlord advance notice of the condition and the action, but if such notice is not reasonable under the circumstances, shall give notice to Landlord as soon as practicable. Tenant shall not have any such right with respect to any condition which Landlord intends to remedy in accordance with a comprehensive plan, intended to manage the necessary repair or replacement, which has been communicated to Tenant. In the event that Tenant remedies such imminent threat or condition preventing the conduct of Tenant’s business in the Premises, Landlord shall reimburse Tenant for all actual out-of-pocket costs reasonably incurred in connection which such repairs completed by Tenant hereunder within thirty (30) days after submission by Tenant to Landlord of a statement of such costs and a request for reimbursement thereof, together with reasonable back up documentation. In the event Landlord does not, within such thirty (30) day period following the submission of the request for reimbursement and the necessary documentation, make payment of the full amount for which Tenant submitted a request for reimbursement, Tenant may cause the matter to be submitted to arbitration by notice given to Landlord within five (5) business days of the end of the end of the thirty (30) day period, in which event Landlord and Tenant shall, during the ensuing ten (10) business days, attempt to agree on an arbitrator not affiliated with either party (and if they are unable to do so, either party may request that the President of the American Arbitration Association in Boston choose an arbitrator, as promptly as possible, meeting the criteria set forth below; provided, however, the parties shall each have the right during a five (5) business day period following the end of the ten (10) business day period to submit the names of not more than two (2) potential arbitrators meeting the said criteria and if the parties or either of them makes such a submission, the choice of the President of the American Arbitration Association shall be made from the list of potential arbitrators so submitted). The arbitrator shall have a period of ten (10) business days to determine (1) whether Tenant was authorized under this Section 8.02 to make the repairs made by it and (2) if so authorized the amount which Tenant is entitled to be reimbursed consistent with the rights of Tenant and the obligations of Landlord under this Section 8.02. If any amount

is owed by Landlord in addition to any amount which Landlord may have theretofore paid to Tenant with respect hereto, Landlord shall pay such amount within thirty (30) days following the decision of the arbitrator and if Landlord does not make such payment within such thirty (30) day period, Tenant may offset the amount the arbitrator determined was due to Tenant, less any portion thereof theretofore paid to Tenant, from Base Rent thereafter becoming due under this Lease. The arbitrator shall be a person with knowledge of commercial office property management (and not less than ten (10) years’ experience in the field of property management) sufficient to enable such person (a) to assess the requirement for Tenant having taken the actions taken by Tenant and (b) to analyze the cost of the repair work undertaken to assure the reasonability thereof. The expenses of the arbitrator shall be borne equally by the Landlord and the Tenant.

8.03 Interruption of Services. Tenant agrees that Landlord shall not be liable in damages, by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any service, or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by repairs, renewals, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at the Building after reasonable effort so to do, by any accident or casualty whatsoever, by act or default of Tenant or other parties, or by any other cause beyond Landlord’s reasonable control; and such failures or delays or diminution (any such event, a “Service Failure”) shall never be deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent or performing any of its obligations under this Lease. Notwithstanding the foregoing, if the Premises, or a material portion of the Premises, is made untenantable (that is, Tenant cannot conduct its business in such portion) or inaccessible for a period in excess of five (5) consecutive business days as a result of the Service Failure that has been caused by Landlord’s act or omission with respect to matters within Landlord’s control (“Controlled Service Failure”), then Tenant, as its sole remedy, shall be entitled to receive an abatement of Rent payable hereunder during the period beginning on the sixth (61 ) consecutive business day of the Controlled Service Failure and ending on the day the service has been restored. If the entire Premises has not been rendered untenantable or inaccessible by such a Controlled Service Failure, the amount of abatement that Tenant is entitled to receive by reason of such a Controlled Service Failure shall be prorated based upon the percentage of the Premises rendered untenantable or inaccessible and not used by Tenant. Notwithstanding the foregoing, business days during which the Premises or a material portion thereof are untenantable or inaccessible, or during which all or nearly all the Premises are unusable, by reason of a Service Failure which arises from a fire or other casualty which is covered by the provisions of ARTICLE 13 shall in no event be considered in determining whether Tenant is entitled to an abatement of Rent under this Section 8.03 (in such event the provisions of Section 13.01 shall govern Tenant’s rights). In no event shall Landlord be liable to Tenant for any loss or damage, including the theft of Tenant’s property, arising out of or in connection with the failure of any security services, personnel or equipment.

8.04 Additional Services. Landlord may, but shall have no obligation to, provide such extra or additional services (beyond the services described in Section 8.01) as it is reasonably possible for Landlord to provide, and as Tenant may from time to time request in writing, within a reasonable period after the time such extra or additional services are requested; furthermore, if extra or additional elevator or heating and air conditioning services are requested, Landlord shall

not be required to furnish any such services unless Landlord has received advance notice from Tenant requesting such services prior to 2:00 p.m. on the business day next preceding the day with respect to which such services are requested. Failure by Landlord to furnish such services shall not constitute an actual or constructive eviction, in whole or in part, or entitle Tenant to any abatement or diminution of Rent, or relieve Tenant from any of its obligations under this Lease, or impose any liability upon Landlord or its agents by reason of inconvenience or annoyance to Tenant, or injury to or interruption of Tenant’s business or otherwise. Tenant shall pay for such extra or additional services at Landlord’s scheduled rate therefor from time to time as quoted to other tenants of the Office Section, or if there be no scheduled rate, then at Landlord’s cost in providing them, such amount to be considered additional Rent hereunder. All charges for such extra or additional services shall be due and payable at the same time as the installment of Base Rent with which they are billed, or if billed separately, shall be due and payable within ten (10) days after Tenant receives Landlord’s xxxx therefor. Any such xxxxxxxx for extra or additional services shall include an itemization of the extra or additional services rendered and the charge for each such service.

8.05 Energy Conservation. Notwithstanding anything to the contrary in this ARTICLE 8 or elsewhere in this Lease, Landlord shall have the right to institute such policies, programs and measures as may be necessary or desirable, in Landlord’s discretion, for the conservation and/or preservation of energy or energy related services if consistent with similar programs instituted generally in first-class office buildings in Boston, or as may be required to comply with any applicable codes, rules and regulations, whether mandatory or voluntary.

ARTICLE 9.
COMPLIANCE WITH LAWS; REPAIRS; HAZARDOUS MATERIALS

9.01 Compliance With Laws. Subject to the following provisions, each of Landlord, in the Base Building Work and in performance of its obligations under Section 8.02, and in its use, ownership, operation and management of the Property, and Tenant, in the Tenant Improvements and any other work it performs in the Building and in its use and occupancy of the Premises, shall comply in all material respects with the requirements of all applicable governmental laws, codes, ordinances, rules and regulations, whether now or hereinafter enacted, including without limitation the Americans With Disabilities Act (42 U.S.C. §12101 et. seq.) and the regulations and accessibility guidelines issued pursuant thereto and the laws set forth in M.G.L. Ch. 22, §13A and the regulations promulgated thereunder (Architectural Access Board Regulations) (collectively, “Legal Requirements”), to the extent that the same are applicable to the Building, and with any and all directions, rules and regulations of Boards of Fire Underwriters, Rating Boards or the like (or successor agencies); and Tenant shall obtain and maintain all permits, licenses and the like, required by all applicable laws in respect of Tenant’s particular use and occupancy of the Premises, as opposed to office use in general. Landlord will cooperate with Tenant’s efforts to obtain any such permits, licenses and the like, at no cost to Landlord. Notwithstanding the foregoing, in no event shall Tenant be responsible or liable for, or obligated to cure, any noncompliance with Legal Requirements existing on or before the Commencement Date, nor shall Tenant be responsible for any future violation of Legal Requirements that results in whole or in part, from Landlord’s acts or omissions or improvements to the Property. Furthermore, Tenant’s obligations under this Section 9.01 shall not include making any structural repairs or improvements to the Building.

9.02 Repairs. Subject to Section 12.01, Tenant will, at Tenant’s own expense, keep the Premises, including all improvements, fixtures and furnishings therein, in good order, repair and condition at all times during the Term, and, except as to damage resulting from ordinary wear and tear, Tenant shall promptly and adequately repair all damage to the Premises and replace or repair all damaged or broken glass, fixtures and appurtenances, under the supervision and subject to the approval of Landlord, and within any reasonable period of time specified by Landlord; provided, however, as to any damage resulting from casualty, Tenant shall have no responsibility for repair or replacement which is Landlord’s responsibility under this Lease. If Tenant does not do so, Landlord may, but shall not be obligated to, make such repairs and replacements, and Tenant shall pay Landlord the cost thereof, including a percentage of the cost thereof (to be uniformly established for the Office Section) sufficient to reimburse Landlord for all overhead, general conditions, fees and other costs or expenses arising from Landlord’s involvement with such repairs and replacements forthwith upon being billed for same. Landlord may, but shall not be required to, enter the Premises at all reasonable times on reasonable advance notice (and at any time in emergency situations, with such notice as is commensurate with the emergency) to make such repairs, alterations, improvements and additions to the Premises, to the Office Section or the Building or to any equipment located in the Office Section or the Building as Landlord shall desire or deem necessary or as Landlord may be required to do by governmental authority or court order or decree.

9.03 Hazardous Materials.

(i) Tenant shall not (either with or without negligence) cause or permit the escape, disposal or release of any biologically or chemically active or hazardous substances, or materials (collectively the “Hazardous Materials”). Tenant shall not allow the storage or use of Hazardous Materials in any manner not sanctioned by law or by the highest standards prevailing in the industry for the storage and use of such Hazardous Materials, nor allow to be brought into the Building any Hazardous Materials except to use in the ordinary course of Tenant’s business, and then only after written notice is given to Landlord of the identity of Hazardous Materials. Without limitation, Hazardous Materials shall include those described in the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, 42 U.S.C. Section 9601 et seq., the Resource Conservation and Recovery Act, as amended, 42 U.S.C. Section 6901 et seq., any applicable state or local laws and the regulations adopted under these acts; provided, however, Hazardous Materials shall not include customary office and cleaning supplies, in reasonable quantities which are maintained and stored in accordance with manufacturer’s specification for maintenance and storage in an office environment. If any lender or governmental agency shall ever require testing to ascertain whether or not there has been any release of Hazardous Materials, then the reasonable costs thereof shall be reimbursed by Tenant to Landlord upon demand as additional charges if such requirement applies to the Premises. In addition, Tenant shall execute affidavits, representations and the like from time to time at Landlord’s request concerning Tenant’s best knowledge and belief regarding the presence of Hazardous Materials on the Premises. In all events, Tenant shall indemnify Landlord in the manner elsewhere provided in this Lease from any release of Hazardous Materials on the Premises occurring while Tenant is in possession or elsewhere if caused by Tenant or persons

acting under Tenant. The within covenants shall survive the expiration or earlier termination of the Term.

(ii) Landlord hereby represents to Tenant that, to the best of its knowledge, there are no Hazardous Materials present on, in or under the land on which the Building is located that require investigation or remediation under applicable law. Tenant shall have no responsibility for and shall not assume or be deemed to have assumed any liability of Landlord on account of oil or Hazardous Materials on, at or in the Property prior to the date Tenant takes possession of the Premises. In no event, unless caused by Tenant or persons for whose conduct Tenant is responsible, shall Tenant be liable for any release of oil or hazardous substances occurring or accruing after the Term. Landlord shall indemnify, defend and hold Tenant harmless from and against any claims, damages, costs and liabilities, including consultants’ fees and reasonable attorneys fees, arising out of Landlord’s use, generation, storage or disposal of hazardous substances or oil on, under or about, or transported to or from, the Building or the Land. Landlord’s indemnification obligations under this Section 9.03(ii) shall survive the expiration or earlier termination of this Lease.

ADDITIONS AND ALTERATIONS

10.01 Consent Required. Tenant shall not, without the prior written consent of Landlord, make any alterations, improvements or additions (sometimes referred to in this Lease, collectively, as “Alterations”) to the Premises, which consent shall not be unreasonably, withheld, conditioned or delayed. Alterations to be made to the Initial Premises prior to the commencement of the Term or made initially to SSB Expansion Space and Early Expansion Space (as those terms are defined under Section 42.01) are referred to in this Lease as the “Initial Alterations”. If Landlord consents to said alterations, improvements or additions, it may impose such conditions with respect thereto as Landlord deems reasonable, including, without limitation, requiring Tenant to provide reasonable assurance that all costs incurred with respect to such work shall be fully and timely paid, insurance against liabilities which may arise out of such work, and plans and specifications plus permits necessary for such work, requiring Tenant to perform such work at times reasonably designated by Landlord; provided, however, such conditions shall not require Tenant to construct Initial Alterations during particular hours (although reasonable rules and regulations relating to regulating noise, odor and vibration resulting from such construction may be imposed). Notwithstanding the foregoing, Landlord’s consent shall not be necessary with respect to Alterations that do not affect the Building systems or structure or the roof skin and (a) are cosmetic in nature (such as paint, carpet and attached furniture) or (b) which in the aggregate (together with any reasonably related set of Alterations) cost less than $50,000.00 plus the costs of painting and carpeting related to the particular Alterations. Tenant shall have the right to hire its own contractors, subject to Landlord’s approval, which approval shall not be unreasonably withheld, conditioned or delayed; provided, that it is agreed that it shall not be unreasonable for Landlord to withhold consent to work in the Building by any contractor with whom Landlord has had quality or cooperation issues in the past. It is further understood that Landlord’s consent to the hiring by Tenant of Tenant’s own contractors may be withheld if Landlord’s permitting such hiring might reasonably be expected to adversely affect other construction in the Building or might reasonably be expected to result in

a material interruption of services provided to tenants of the Building. Any contractor hired by Tenant shall be appropriately insured as reasonably determined by Landlord. Tenant shall promptly pay to the contractor, when due, the cost of all such work and of all decorating required by reason thereof. In connection with seeking Landlord’s approval, plans and specifications regarding proposed Alterations shall be in such form and with such content as Landlord shall reasonably require and Tenant shall, in addition to all other expenses which Tenant is obligated to pay to Landlord hereunder, reimburse Landlord for all sums reasonably expended for unaffiliated third party consultants’ examination and approval of the architectural and working plans and specifications for the Alterations and, except in connection with the Initial Alterations to the Premises, shall pay Landlord for use of elevators and hoists during the making of the Alterations; provided, however, that Landlord shall have the exclusive right to determine the scheduling of (and shall cooperate reasonably with Tenant to coordinate) the use of such elevators and hoists which shall not be unreasonably withheld, conditioned or delayed. Landlord shall review and approve (or provide comments on) Tenant’s plans and specifications no later than ten (10) business days after submission. If Landlord fails to approve, object to or provide comments on Tenant’s submission of a set of plans and specifications within such ten (10) business day period, then Tenant may deliver a notice to Landlord stating that if Landlord fails to approve, object to or provide comments on such plans within two (2) business days following the delivery of such notice, and in such event, if Landlord fails to so approve, object to or provide comments on such plans within such two (2) business day period, Landlord shall be deemed to have approved the submitted set of plans and specifications. If any of the plans and specifications are disapproved by Landlord, Landlord shall provide Tenant with reasonably detailed reasons for such disapproval and the foregoing process shall be repeated until all of the plans and specifications shall have been approved or deemed approved by Landlord, except that Landlord’s approval of any revisions to the plans and specifications submitted in response to Landlord’s comments or objections shall be deemed given unless Landlord submits written comments or objections to Tenant within five (5) business days after receipt thereof, subject to the delivery of a second notice and Landlord’s failure to approve, object to or provide comments within two (2) business days following Landlord’s receipt thereof. Except for the reimbursement for third party consultants at commercially reasonable rates, Tenant will not be charged any Landlord supervisory, management or review fees in connection with any Alterations. Landlord’s architect and base building contractor will reasonably cooperate with Tenant to ensure timely completion of Alterations. Upon completion of such work Tenant shall deliver to Landlord, if payment is made directly to contractors, evidence of payment, contractors’ affidavits and full and final waivers of all liens for labor, services or materials, all in form satisfactory to Landlord. Tenant shall defend and hold Landlord, any mortgagee, the DOT (defined in Article 33U), the Property and the Building harmless from all costs, damages, liens and expenses related to such work. All work done by Tenant or its contractors pursuant to ARTICLES 9 or 10 shall be done in a good and workmanlike manner using only good grades of materials and shall comply with all insurance requirements and all applicable laws and ordinances and rules and regulations of governmental departments or agencies.

10.02 Improvements are Landlord’s Property. All alterations, improvements and additions to the Premises, whether temporary or permanent in character, made or paid for by Landlord or Tenant, shall without compensation to Tenant become Landlord’s property at the termination of this Lease by lapse of time or otherwise; provided, however, all articles of personal property and all business fixtures, machinery and equipment and furniture owned or

installed by Tenant solely at its expense in the Premises (all of which are herein referred to as “Tenant’s Property”) shall remain the property of Tenant and may be removed by Tenant or any person claiming under Tenant at any time or times during the Term and shall be removed by Tenant no later than the expiration or earlier termination of the Term. Any items of Tenant’s Property (except money, securities and like valuables) which remain on the Premises after the Termination Date or earlier termination of the Term shall be deemed to have been abandoned and in such case may either be retained by Landlord as its property or may be removed by Landlord and disposed of at Tenant’s expense (this provision shall survive the termination of this Lease).

10.03 Lines. Tenant may install, maintain, replace, remove or use any communications or computer wires, cables and related devices and fiber optic cabling (collectively the “Lines”) at the Property in or serving the Premises, provided: (a) Tenant shall obtain Landlord’s prior written consent, use an experienced and qualified contractor approved in writing by Landlord in accordance with, and subject to, the procedures and standards for approvals of contractors performing Alterations, and comply with all of the other provisions of ARTICLE 10.01, (b) any such installation, maintenance, replacement, removal or use shall not interfere with the use of any then existing Lines at the Building, (c) an acceptable number of spare Lines and space for additional Lines shall be maintained for existing and future occupants of the Building, as determined in Landlord’s reasonable opinion, (d) if Tenant at any time uses any equipment that may create an electromagnetic field exceeding the normal insulation ratings or ordinary twisted pair riser cable or cause radiation higher than normal background radiation, the Lines therefor (including riser cables) shall be appropriately insulated to prevent such excessive electromagnetic fields or radiation, (e) Tenant’s rights shall be subject to the rights of any regulated telephone company, and (f) Tenant shall pay all costs in connection therewith. Landlord reserves the right to require that Tenant remove any Lines located in or serving the Premises which are installed in violation of these provisions, or which are at any time in violation of any laws, ordinances, rules or regulations or represent a dangerous or potentially dangerous condition (whether such Lines were installed by Tenant or any other party claiming under Tenant), within fifteen (15) days after written notice.

Landlord may (but shall not have the obligation to): (i) install new Lines at the Building, (ii) create additional space for Lines at the Property, and (iii) reasonably direct, monitor and/or supervise the installation, maintenance, replacement and removal of, the allocation and periodic re-allocation of available space (if any) for, and the allocation of excess capacity (if any) on, any Lines now or hereafter installed at the Building by Landlord, Tenant or any other party (but Landlord shall have no right to monitor or control the information transmitted through such Lines). Such rights shall not be in limitation of other rights that may be available to Landlord by law or otherwise. If Landlord exercises any such rights, Landlord may charge Tenant for the costs attributable to Tenant, or may include those costs and all other costs in Operating Expenses under ARTICLE 5 (including without limitation, costs for acquiring and installing Lines and risers to accommodate new Lines and spare Lines, any associated computerized system and software for maintaining records of Line connections, and the fees of any consulting engineers and other experts); provided, any capital expenditures included in Operating Expenses hereunder shall be amortized (together with reasonable finance charges) as provided in subsection 5.02(v).

Tenant shall not be required to remove any or all Lines installed by or for Tenant within or serving the Premises upon termination of this Lease. All Lines shall become the property of Landlord (without payment by Landlord) upon termination of this Lease. Tenant shall not, without the prior written consent of Landlord in each instance, grant to any third party a security interest or lien in or on the Lines, and any such security interest or lien granted without Landlord’s written consent shall be null and void. Except to the extent arising from the intentional or negligent acts of Landlord or Landlord’s agents or employees, Landlord shall have no liability for damages arising from, and Landlord does not warrant that the Tenant’s use of any Lines will be free from the following (collectively called “Line Problems”): (x) any eavesdropping or wire-tapping by unauthorized parties, (y) any failure of any Lines to satisfy Tenant’s requirements, or (z) any shortages, failures, variations, interruptions, disconnections, loss or damage caused by the installation, maintenance, replacement, use or removal of Lines by or for other tenants or occupants at the Building, by any failure of the environmental conditions or the power supply for the Building to conform to any requirements for the Lines or any associated equipment, or any other problems associated with any Lines by any other cause. Under no circumstances shall any Line Problems be deemed an actual or constructive eviction of Tenant, render Landlord liable to Tenant for abatement of Rent, or relieve Tenant from performance of Tenant’s obligations under this Lease. Landlord in no event shall be liable for damages by reason of loss of profits, business interruption or other consequential damage arising from any Line Problems.

10.04 Specialty Alterations. Subject to the foregoing provisions, Tenant shall have the right to construct within the Premises computer rooms and any other specialized facilities, and may connect floors of the Premises by the installation of interconnecting stairs, as long as any such work does not impact the structural integrity of the Building; provided, however, if Tenant elects to construct any such installations or additions, or any other installations or additions which are not typical office-related leasehold improvements that require substantial or unusual expense to re-adapt the Premises for normal office purposes (collectively, “Specialty Alterations”), Landlord shall notify Tenant of Tenant’s removal or restoration obligations with respect to any Specialty Alterations at the time of Landlord’s approval of such Specialty Alterations, and Tenant shall be obligated to remove any identified Specialty Alterations at the expiration of the Term; provided, however, Landlord hereby agrees that Tenant shall not be required to remove or restore any of Tenant’s Initial Alterations (or Alterations that were comparable replacements of Initial Alterations) whether or not the same are Specialty Alterations.

ARTICLE 11.
COVENANT AGAINST LIENS

Tenant has no authority or power to cause or permit any lien or encumbrance of any kind whatsoever, whether created by act of Tenant, operation of law or otherwise, to attach to or be placed upon the Property, the Building or the Premises, or to affect any estate or interest of Landlord, Landlord’s lessor, any mortgagee or the DOT (defined in ARTICLE 33U). Tenant covenants and agrees not to suffer or permit any lien of mechanics, materialmen or others to be placed against the Property, the Building or the Premises, or to affect any estate or interest of Landlord, Landlord’s lessor, any mortgagee or the DOT, with respect to work or services claimed to have been performed for or materials claimed to have been furnished to Tenant or the

Premises, and, in case of any such lien attaching or notice of any lien, or claim therefor being asserted, Tenant covenants and agrees to cause same to be released and removed of record, by payment or bonding over within thirty (30) days after Tenant’s actual knowledge thereof. In the event that such lien is not so released and removed, Landlord, at its sole option, may take all action necessary to release and remove such lien (without any duty to investigate the validity thereof) and Tenant shall promptly upon notice reimburse Landlord for all sums, costs and expenses (including reasonable attorneys’ fees) incurred by Landlord in connection therewith.

ARTICLE 12.
INSURANCE

12.01 Waiver of Subrogation. Landlord and Tenant each hereby waive any and every claim for recovery from the other for any and all loss of or damage to the Property, Building or the Premises or to the contents thereof, which loss or damage is covered by valid and collectible physical damage insurance policies, to the extent that such loss or damage is recoverable under said insurance policies. Inasmuch as this mutual waiver will preclude the assignment of any such claim by subrogation (or otherwise) to an insurance company (or any other person), Landlord and Tenant each agree to give to each insurance company which has issued, or in the future may issue, to its policies of physical damage insurance, written notice of the terms of this mutual waiver, and to have said insurance policies properly endorsed, if necessary, to prevent the invalidation of said insurance coverage by reason of said waiver. Tenant’s waiver of subrogation as hereinabove set forth shall also run to the benefit of and extend to Landlord’s lessor and the DOT.

12.02 Coverage. Tenant shall purchase and maintain insurance during the entire Term for the benefit of Tenant, and, except for personal property insurance maintained by Tenant other than with respect to leasehold improvements, for the benefit of Landlord, the DOT and any mortgagee of which Tenant is given notice (as their respective interests may appear) (collectively, the “Insured Landlord Parties”) with terms, coverages and in companies reasonably satisfactory to Landlord, and with such increases in limits as Landlord may from time to time request and which are consistent with increases required of similar office tenants in Class A office buildings in Boston, but initially Tenant shall maintain the following coverages in the following amounts:

(i) Commercial General Liability. Commercial General Liability Insurance covering the Insured Landlord Parties and Landlord’s management agent for claims of bodily injury, personal injury and property damage arising out of Tenant’s operations, assumed liabilities or use of the Premises, for limits of liability not less than:

Bodily Injury and Property		$3,000,000 each occurrence

Damage Liability		$3,000,000 annual aggregate

Personal Injury Liability		$3,000,000 annual aggregate

		0% Insured’s participation

(ii) Comprehensive Automobile. Comprehensive Automobile Insurance covering all owned, non-owned and hired automobiles of Tenant including the loading and unloading of any automobile with limits of liability not less than:

Bodily Injury and Property		$3,000,000 each occurrence

Damage Liability		$3,000,000 annual aggregate

(iii) Physical Damage. Physical Damage Insurance covering all additions, improvements and alterations to the Premises which are beyond the building standard tenant improvements provided by Landlord and all office furniture, trade fixtures, office equipment, merchandise and all other items of Tenant’s property on the Premises. Such insurance shall be written on an “all risks” of physical loss or damage basis, for the full replacement cost value of the covered items and in amounts that meet any coinsurance clauses of the policies of insurance.

(iv) Improvements and Betterments. From and after the time Tenant takes control of the Premises for purposes of its construction, Improvements and Betterments Insurance completed value (non-reporting) form coverage, including “all-risk” type coverage and coverage against the perils normally covered by a special extended coverage endorsement, collapse, cost of demolition, increased cost of construction and the value of the undamaged portion of the construction being undertaken by Tenant, in customary form for Massachusetts construction projects and to be maintained in such amounts as to afford one hundred percent (100%), non-contributory coverage against loss.

Tenant may provide such of the foregoing insurance coverage under a so-called blanket policy providing adequate coverage in Landlord’s reasonable judgment for the properties and risks being covered thereby. In the event Tenant elects to use a blanket policy, Tenant shall specifically notify Landlord thereof and provide such information regarding the properties and risks covered thereby as Landlord shall reasonably request. Tenant may, in addition, satisfy the limits requirements through umbrella coverage written with companies which would satisfy the provisions of this ARTICLE if such companies were providing the underlying coverage hereunder.

Tenant shall, prior to the commencement of the Term, furnish to Landlord certificates evidencing such coverage, on XXXXX Form 27, which certificates shall state that such insurance coverage may not be changed or canceled without at least thirty (30) days’ prior written notice to Landlord and Tenant and shall name Landlord and Landlord’s management agent as additional insureds (other than with respect to the insurance described in subsection 12.02(iii) above).

12.03 Avoid Action Increasing Rates. Tenant shall comply with all applicable laws and ordinances, all orders and decrees of court and all requirements of other governmental authorities having jurisdiction over the Building and of the applicable rating bureau, and shall not, directly or indirectly, make any use of the Premises which may thereby be prohibited or be dangerous to person or property or which may jeopardize any insurance coverage or may increase the cost of insurance or require additional insurance coverage. If by reason of the failure of Tenant to

comply with the provisions of this Section 12.03, (i) any insurance coverage is jeopardized, or (ii) insurance premiums are increased, Landlord shall have the option to require Tenant to make immediate payment of the increased insurance premium and if Tenant fails to do so, such failure shall constitute a default in the payment of Rent due under this Lease.

12.04 Landlord’s Insurance. Landlord agrees to maintain in full force and effect throughout the Term (i) Commercial General Liability Coverage with respect to the Property, and the conduct and operation of its business therein, with combined commercial general liability and umbrella coverage limits of not less than Ten Million Dollars ($10,000,000.00) for bodily injury or death and property damage in any one occurrence and shall name Tenant as an additional insured; and (ii) Cause of Loss Special Form property insurance (including commercially reasonable amounts of loss of rents coverage, as long as such coverage is available at commercially reasonable rates) with respect to the Building and the Building’s equipment and personal property, but excluding Tenant’s property and any alterations made by Tenant, in an amount equal to the replacement cost of the equipment and personal property that Landlord is obligated to insure hereunder.

ARTICLE 13.
FIRE OR OTHER CASUALTY

13.01 Effect of Casualty. ARTICLE 9 hereof notwithstanding, if the Premises or the access thereto shall be damaged by fire or other casualty and if such damage does not render all or a material portion of the Premises untenantable and if the Premises, the Office Section or the Building are not substantially damaged (as hereinafter defined), then Landlord shall, subject to building and zoning laws then applicable, repair and restore the same with reasonable promptness, subject to reasonable delays for insurance adjustments and delays caused by matters beyond Landlord’s reasonable control, but shall not be obligated to expend therefor an amount in excess of the proceeds of insurance recovered with respect thereto plus any associated deductible amount. If all or a material portion of the Premises are rendered untenantable by fire or other casualty, or if the Premises, the Office Section or the Building are substantially damaged by fire or other casualty (the term “substantially damaged” meaning damage of such a character that the same cannot, in the ordinary course, reasonably be expected to be repaired within one hundred eighty (180) days from the time that repair work would commence) and Landlord is terminating all other leases in Tower IV, then, in either such case, Landlord shall have the right to terminate this Lease by giving notice of Landlord’s election so to do not later than one hundred twenty (120) days after Landlord has ascertained all information required by Landlord to determine whether or not to terminate this Lease, including without limitation the amount of insurance proceeds which are available to Landlord for restoration. If all or a material portion of the Premises or access thereto are so damaged by fire or other casualty that the Premises are rendered untenantable (reasonable commercial access to the Premises being necessary for the Premises to be “tenantable”) for the operation of Tenant’s business for a period reasonably estimated by Landlord to exceed two hundred forty (240) days or if the damage is not in fact repaired so that the Premises are tenantable for the operation of Tenant’s business within such two hundred forty (240) day period, then Tenant shall have the right to terminate this Lease by giving notice of Tenant’s election to terminate not later than thirty (30) days after (a) receiving notice from Landlord that the period for repair will exceed two hundred forty (240) days or (b) the end of such two hundred forty (240) day period if the Premises are not in fact tenantable at

the end of such period. In the event a party entitled to do so gives such termination notice, this Lease shall terminate (with appropriate proration(s) of Rent being made for Tenant’s possession of the tenantable portion of the Premises after the date of such damage) as of the date specified in such notice (but in no event sooner than thirty (30) days after the date of such notice) with the same force and effect as if the date specified were the date originally established as the expiration date hereof. Except as aforesaid, Landlord shall have no liability to Tenant, and except as specifically provided above, Tenant shall not be entitled to terminate this Lease by virtue of any delays in completion of such repairs and restoration. Further, in the event this Lease is not terminated, Landlord shall not be obligated to restore any portion of the Office Section or the Building outside of the Premises which is not necessary for reasonable access to and egress from the Premises. Rent shall xxxxx on those portions of the Premises as are, from time to time, untenantable as a result of such damage.

13.02 Intentionally Omitted.

13.03 Responsibility for Reconstruction of Improvements. Notwithstanding anything to the contrary herein set forth, Landlord shall have no duty pursuant to this ARTICLE 13 to repair or restore any portion of the alterations, additions or improvements in the Premises or the decorations hereto except to the extent that such alterations additions, improvements and decorations were paid by requisitions from any allowance provided by Landlord to Tenant and only to the extent of the insurance proceeds with respect thereto paid to Landlord by Tenant or its insurers. If Tenant desires any other or additional repairs or restoration, the same shall be done at Tenant’s sole cost and expense subject to all of the provisions of ARTICLE 9 and ARTICLE 10 hereof. Tenant acknowledges that Landlord shall be entitled to the full proceeds of any insurance coverage, whether carried by Landlord or Tenant, for damage to alterations, additions, improvements or decorations provided by Landlord either directly or through an allowance to Tenant.

ARTICLE 14.
WAIVER OF CLAIMS -INDEMNIFICATION

14.01 Tenant’s Indemnification. To the extent not prohibited by law, Landlord, its partners, its managing agent, Landlord’s lessor, any mortgagee, the DOT and their respective officers, agents, servants and employees shall not be liable for any damage either to person or property or resulting from the loss of use thereof sustained by Tenant or by other persons due to the Building or any part thereof or any appurtenances thereof becoming out of repair, or due to the happening of any accident or event in or about the Office Section, the Premises or the Building, or due to any act or neglect of any tenant or occupant of the Office Section, the Building or of any other person or entity. This provision shall apply particularly, but not exclusively, to damage caused by gas, electricity, snow, frost, steam, sewage, sewer gas or odors, fire, water, noise, vibration, fumes or by the bursting or leaking of pipes, faucets, sprinklers, plumbing fixtures and windows, and shall apply without distinction as to the person whose act or neglect was responsible for the damage and whether the damage was due to any of the causes specifically enumerated above or to some other cause of an entirely different kind. Tenant further agrees that all personal property upon the Premises, or upon loading docks, receiving and holding areas, or freight elevators of the Building shall be at the risk of Tenant only, and that Landlord shall not be liable for any loss or damage thereto or theft thereof. Without limitation of

any other provisions hereof, Tenant agrees to defend, protect, indemnify and save harmless Landlord, Landlord’s lessor, any mortgagee and the DOT from and against all liability to third parties which arose (or which were claimed to have arisen) within or without the Premises during the Term of this Lease or out of acts or omissions of Tenant and its servants, agents, employees, contractors, suppliers, workers and invitees, except to the extent such liability arises from the negligence of Landlord, its property manager or its agents. The foregoing indemnity shall survive the expiration or earlier termination of this Lease.

14.02 Landlord’s Indemnification. To the maximum extent this agreement may be made effective according to law, Landlord agrees to indemnify and save harmless Tenant from and against all liabilities for claims by third parties arising from any accident, injury or damage to any person, or to the property of any person occurring on the Property, including any accident, injury or damage in connection with the Landlord’s Work, where such accident, damage or injury results from negligence of Landlord, its property manager or Landlord’s agents, or from a breach by Landlord of its representations and warranties set forth in this Lease. The foregoing indemnity shall survive the expiration or earlier termination of this Lease.

ARTICLE 15.
NONWAIVER

No waiver of any provision of this Lease shall be implied by any failure of Landlord or Tenant to enforce any remedy against the other on account of the violation of such provision, even if such violation be continued or repeated subsequently, and no express waiver shall affect any provision other than the one specified in such waiver and that one only for the time and in the manner specifically stated. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Term or of Tenant’s right of possession hereunder or after the giving of any notice shall reinstate, continue or extend the Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a suit or after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment.

ARTICLE 16.
CONDEMNATION

If the Property, the Building or any portion thereof shall be taken or condemned by any competent authority for any public or quasi-public use or purpose (a “taking”), or if the configuration of any roadway, street, alley, or railroad line adjacent to or beneath the Building is changed by any competent authority and such taking or change in configuration makes it necessary or desirable to remodel or reconstruct the Building or any part thereof, Landlord shall have the right, exercisable at its sole discretion, to cancel this Lease upon not less than ninety (90) days’ notice prior to the date of cancellation designated in the notice. No money or other consideration shall be payable by Landlord to Tenant for the right of cancellation and Tenant shall have no right to share in the condemnation award or in any judgment for damages caused by such taking or change in configuration; provided, however, nothing herein shall prevent Tenant from pursuing a judgment from the taking authority for its moving expenses, the unamortized costs of improvements paid for by Tenant (and not paid by Landlord allowance) and

trade fixtures so long as pursued in a separate action which will not result in a reduction of any award otherwise payable to Landlord (except for the cost of such Tenant’s trade fixtures, unamortized improvements (not paid by allowance) or the Tenant’s expense of moving that might otherwise have been paid to Landlord). In the event that any part of the Premises shall be taken by any public authority or for any public use and the remainder, even after restoration, would not be reasonably suitable for Tenant’s use, in Tenant’s bona fide business judgment, or in the event that a taking results in a permanent loss of adequate parking or a permanent deprivation of all reasonable commercial access to the Premises, then this Lease may be terminated at the election of Tenant, which election shall be made by giving of notice by Tenant to Landlord within thirty (30) days after the date of the taking.

ARTICLE 17.
ASSIGNMENT AND SUBLETTING

17.01 No Transfer Without Consent. Tenant shall not, without the prior written consent of Landlord (which consent shall not be unreasonably conditioned, delayed or withheld), (i) assign, convey or mortgage this Lease or any interest hereunder; (ii) permit to occur or exist any assignment of this Lease, voluntarily or by operation of law; (iii) sublet the Premises or any part thereof; or (iv) permit the occupancy of the Premises by any parties other than Tenant, its affiliates and their employees. Any such action (each, a “Transfer’’) on the part of Tenant to any assignee, sublessee or other transferee (each assignee, sublessee or other transferee being referred to herein as a “Transferee”), without Landlord’s consent to the extent such consent is required, shall be void and of no effect. Landlord’s consent to any Transfer or Landlord’s election to accept any Transferee as the tenant hereunder and to collect rent from such Transferee shall not release Tenant or any subsequent tenant of the Premises from any covenant or obligation under this Lease. Landlord’s consent to any Transfer shall not constitute a waiver of Landlord’s right to withhold its consent to any future Transfer.

Notwithstanding any contrary provision of this Lease, Tenant shall have the right, without the prior consent of Landlord, to assign this Lease and to sublet all or any portion of the leased Premises to any person or entity (a) controlling, controlled by, or under common control with Tenant, (b) acquiring all or substantially all of the assets of Tenant, or (c) with or into which Tenant merges or consolidates, whether by statutory merger, sale of stock, or otherwise (any of the foregoing (a)-(c), a “Related Party Transfer”), so long as (i) the principal purpose of such assignment or sublease is not the acquisition of Tenant’s interest in this Lease by a third party, (ii) the assignment or sublet is not made to circumvent the provisions of this Section 17.01, and (iii) the assignee or successor under (b) or (c) succeeds to all or substantially of Tenant’s business conducted within the Premises immediately prior to such assignment or sublet. In no event shall any business reorganization (e.g., a change in corporate form of Tenant), nor any change in Tenant’s shareholders, partners, or other beneficial owners in the conduct of Tenant’s business, be deemed an assignment of Tenant’s interest in this Lease.

Landlord agrees that the Premises may be occupied without the need for any sublease during the Term by any persons or entities which in the aggregate occupy not more than five percent (5%) of the Premises if such persons or entities are during the period of occupancy involved in a then current engagement with Tenant, current consultants to Tenant actively

involved in furnishing consulting services during such period, or a member of Tenant or any affiliate thereof, to whom Tenant is providing courtesy office space.

No Transfer or Related Party Transfer shall release the transferor from primary liability with the transferee for all of the Tenant’s obligations under this Lease.

The parties hereby agree that it shall be reasonable under this Lease and under any applicable law for Landlord to withhold consent to any proposed Transfer requiring Landlord’s consent where one or more of the following applies (without limitation as to other reasonable grounds for withholding consent, Landlord acknowledging that the rental rate is not a reasonable ground for withholding consent under this Lease): (i) the Transferee is of a character or reputation or engaged in a business which is not consistent with the quality of the Property; (ii) the Transferee intends to use the Premises or a portion thereof for purposes which are not permitted under this Lease; (iii) the Transferee is either (x) a government (or agency or instrumentality thereof), (y) an occupant of the Property (unless Landlord does not have comparable space in the Building that is suitable for use by such occupant), or (z) a prospective tenant of the Property with whom Landlord is actively negotiating at the time Tenant proposes to make the Transfer; (iv) Tenant is in monetary default (or any other default which has continued beyond applicable notice and cure periods) as described in ARTICLE 24; (v) the proposed Transferee’s anticipated use of the Premises involves the generation, storage, use, treatment or disposal of Hazardous Materials in a manner not otherwise permitted by this Lease; (vi) the proposed Transferee is in any way affiliated with organizations which sponsor terrorist organizations regardless of the use to be made of the Premises by the proposed Transferee; (vii) the corridor pattern resulting from demising the sublease space would result in access to leasable space serviced by that corridor being inconsistent with the corridor pattern of a first- class office building; or (viii) in the reasonable judgment of Landlord acting in good faith, such a Transfer would violate any term, condition, covenant or agreement of the Landlord involving the Property. If Landlord wrongfully withholds its consent to any Transfer, Tenant’s sole and exclusive remedy therefor shall be to seek specific performance of Landlord’s obligation to consent to such Transfer.

17.02 Rent Premium on Transfer. Without limitation of the rights of Landlord hereunder in respect thereto, (i) if there is any assignment of this Lease by Tenant or a subletting or other Transfer of the whole of the Premises (other than a Related Party Transfer, which shall not be subject to the provisions of this Section 17.03) by Tenant, or (ii) if Tenant, as debtor or debtor in possession, or a trustee in bankruptcy for Tenant pursuant to the Bankruptcy Code, 11 U.S.C. 101 et. seq., as amended from time to time (the “Bankruptcy Code”), shall assign this Lease or sublet the Premises, or any part thereof, at a rent or for other consideration which, in any such case, is in excess of the sum of (x) the subleased portion’s pro rata share of the rent payable hereunder by Tenant for the period of the sublease or the amount payable for the assigned space over the remaining term of this Lease with respect thereto, and (y) the Reasonable Transfer Costs (as hereinafter defined), then Tenant shall pay to Landlord, as additional rent, (a) with respect to an assignment of this Lease fifty percent (50%) of the amount by which the total consideration received or to be received by Tenant in connection with the assignment exceeds the Reasonable Transfer Costs and (b) with respect to a sublease, fifty percent (50%) of the amount by which the total consideration received or to be received by Tenant in connection with the sublease exceeds the sum of the rent applicable to the subleased space and the Reasonable Transfer Costs (the

“Sublease Premium”). “ Reasonable Transfer Costs” shall mean any tenant improvement allowance paid or credited to the transferee by Tenant, customary brokerage commissions not reimbursed by the transferee or paid directly by the transferee, legal, advertising and marketing expenses, free rent allowances, alteration costs and expenses of preparation of the Premises (or portion thereof) for the transferee. With respect to an assignment of this Lease, the amount payable to Landlord hereunder shall be paid to Landlord by Tenant as a first charge against the consideration received by Tenant and payment shall be made by Tenant within thirty (30) days of Tenant having received consideration in connection with the assignment (Tenant shall pay the first charge as consideration is received so that if there are installments of consideration, the payment to Landlord shall be made from each installment as such first charge until the full amount due to Landlord shall have been paid). With respect to a sublease, for each month commencing with the first month in which the subtenant pays any consideration to or for the benefit of the Tenant (the “Sublease Start Month”) through the month in which Landlord receives payment or gets other consideration from Tenant in connection with the sublease, Tenant shall pay to Landlord (each such monthly payment to Landlord, an “On-Account Premium Payment”) an amount equal to (a) 50% of (i) the total of all such consideration theretofore paid to or for the benefit of Tenant with respect to the subleasing through the end of such month for which the calculation is being made (the “Calculation Period”) less (ii) the Rent payable by Tenant under this Lease for the Calculation Period less (iii) the Amortized Reasonable Transfer Costs for the Calculation Period, reduced by (b) the total of On-Account Premium Payments theretofore made by Tenant. Tenant shall pay the On-Account Premium Payment due with respect to any calendar month within ten (10) business days following such calendar month. “Amortized Reasonable Transfer Costs” shall mean the Reasonable Transfer Costs (A) divided by the number of calendar months between, and including, the first calendar month with respect to which the subtenant pays any rent to Tenant or provides a benefit to Tenant (such as paying a cost otherwise customarily or legally the responsibility of Tenant) and the last calendar month of the term of the sublease multiplied by (B) the number of calendar months commencing with the first calendar month with respect to which the subtenant paid rent through the calendar month in which the payment due Landlord is being calculated. The provisions of this Section 17.03 shall apply to each and every assignment of this Lease and each and every subletting or other Transfer of all or a portion of the Premises, other than Related Party Transfers, in each case on the terms and conditions set forth herein. Each request by Tenant for permission to assign this Lease or to sublet the whole or any part of the Premises shall be accompanied by a certification of an executive officer of Tenant as to the elements of consideration paid or to be paid by the assignee or subtenant, however characterized, and the time periods with respect to which such payments have been or will be made together with a calculation, based thereon, of the amount due Landlord under this Section 17.02 by reason of the assignment or sublet. For the purposes of this Section 17.03, the consideration paid by the transferee shall mean all Base Rent, Additional Rent or other payments and/or consideration payable by one party to another related to the use and occupancy of all or a portion of the Premises.

17.03 Change in Control. If Tenant is a corporation or a limited liability company (other than a corporation whose stock is traded through a national or regional exchange or over-the- counter), any transaction or series of transactions (including without limitation any dissolution, merger, consolidation or other reorganization of Tenant, or any issuance, sale, gift, transfer or redemption of any capital stock of Tenant, whether voluntary, involuntary or by operation of

law, or any combination of any of the foregoing transactions) resulting in the transfer of control of Tenant, other than by reason of death, shall be deemed to be a Transfer for the purpose of this ARTICLE 17. If Tenant is a partnership, any transaction or series of transactions (including without limitation any withdrawal or admittance of a partner or any change in any partners’ interest in Tenant, whether voluntary, involuntary or by operation of law, or any combination of any of the foregoing transactions) resulting in the transfer of control of Tenant, other than by reason of death, shall be deemed to be a Transfer for purposes of this ARTICLE 17. The term “control” as used in this Section 17.03 means the power to directly or indirectly direct or cause the direction of the management or policies of Tenant. If Tenant is a corporation or a limited liability company, a change or series of changes in ownership of stock which would result in direct or indirect change in ownership by the stockholders or an affiliated group of stockholders (or members) of less than fifty percent (50%) of the outstanding voting stock of Tenant as of the date of the execution and delivery of this Lease shall not be considered a change of control; provided, however, a sale of part or all of the corporate shares of Tenant resulting in a change in control of Tenant shall not require Landlord’s consent if more than 50% of the voting power is held by twenty-five (25) or more unrelated shareholders or distributed to such number of unrelated shareholders in a public offering registered with the Securities and Exchange Commission. For purposes of clarity, Landlord acknowledges that although a transaction which results in a change in control may be a Transfer under this Article 17, Landlord’s consent thereto is not required and no amount shall be due under Section 17.02 with respect to any such Transfer which is a Related Party Transfer (although a subsequent change in control of a party who succeeded to an interest in this Lease or the Premises (or a part thereof) in a Related Party Transfer shall require consent and/or payment of an amount under Section 17.02 if such Transfer does not itself constitute a Related party Transfer.

ARTICLE 18.
SURRENDER OF POSSESSION

Upon the expiration of the Term or upon the termination of Tenant’s right of possession to all or a portion of the Premises, whether by lapse of time or at the option of Landlord as herein provided, Tenant shall forthwith quietly and peaceably surrender the Premises or portion thereof to Landlord in good order, repair and condition, ordinary wear excepted. Any interest of Tenant in the alterations, improvements and additions to the Premises made or paid for by Landlord or Tenant shall, without compensation to Tenant, become Landlord’s property at the termination of this Lease by lapse of time or otherwise and if such option is exercised such alterations, improvements and additions shall be relinquished to Landlord in good condition, ordinary wear excepted. Prior to the termination of the Term or of Tenant’s right of possession Tenant shall remove office furniture, trade fixtures, office equipment and all other items of Tenant’s property on the Premises. Tenant shall pay to Landlord upon demand the cost of repairing any damage to the Premises and to the Building caused by any removal required hereunder. If Tenant shall fail or refuse to remove any such property from the Premises, Tenant shall be conclusively presumed to have abandoned the same, and title thereto shall thereupon pass to Landlord without any cost either by set-off, credit, allowance or otherwise, and Landlord may at its option accept the title to such property or, at Tenant’s expense, may (i) remove the same or any part in any manner that Landlord shall choose, repairing any damage to the Premises caused by such removal, and (ii) store, destroy or otherwise dispose of the same without incurring liability to Tenant or any other person.

ARTICLE 19.
HOLDING OVER

In addition to performing all of Tenant’s other obligations hereunder, if Tenant retains possession of the Premises or any part thereof after the expiration of the Term, such holding over shall be on the terms and conditions as set forth in this Lease, as far as applicable, except that Tenant shall pay, as a use and occupancy charge with respect to, in addition to all other charges for which Tenant would be liable hereunder if it were occupying during the term of this Lease, during the first thirty (30) days of such holdover 150% of the Base Rent and the Adjustment Amount payable under the terms of this Lease for and with respect to the last full calendar month immediately prior to the expiration of the Term and after such initial thirty (30) day period for each calendar month or portion thereof during which such holdover continues, as a use and occupancy charge with respect to, in addition to all other charges for which Tenant would be liable hereunder if it were occupying during the term of this Lease, an amount equal to 150% of the higher of (x) the Base Rent and the Adjustment Amount payable under the terms of this Lease for and with respect to the last full calendar month immediately prior to the expiration of the Term or (y) one twelfth of the annual fair market rent for the Premises under a one (1) year lease commencing on the day immediately succeeding the last day of the Term. Amounts due as aforesaid shall be prorated for partial months on a per diem basis. Notwithstanding anything to the contrary herein contained, Landlord shall have the right to commence eviction proceedings against Tenant immediately upon any holding over by Tenant in the Premises.

In addition, Tenant shall indemnify, defend and hold Landlord harmless from and against any loss, cost or damages (including, without limitation reasonable attorneys’ fees) which Landlord may suffer by reason of any such holdover by Tenant for a period of longer than thirty (30) days. The provisions of this ARTICLE 19 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law.

ARTICLE 20.
ESTOPPEL CERTIFICATE

Tenant agrees that, from time to time upon not less than twenty (20) days’ prior request by Landlord, Landlord’s lessor or any mortgagee, Tenant or Tenant’s duly authorized representative having knowledge of the following facts will deliver to Landlord a statement in writing certifying (i) that this Lease is unmodified (or if there have been modifications, a description of such modifications), (ii) to the best of Tenant’s knowledge, this Lease (as modified if there were modifications) is in full force and effect, (iii) the dates to which Rent and other charges have been paid; (iv) to the best of Tenant’s knowledge, that Landlord is not in default under any provision of this Lease, or, if in default, the nature thereof in detail; (v) if true, that the Premises have been delivered to Tenant by Landlord and accepted by Tenant; (vi) that there are no proceedings pending against Tenant which have been adversely decided and which would affect Tenant’s obligations under this Lease (or if there are such proceedings, identifying such proceedings; (vii) that Tenant has not made a claim against Landlord which has not been resolved or satisfied (or is any such claim has not been resolved or satisfied, stating such claims and its status); and (viii) such further matters as may reasonably be requested by Landlord; it being intended that any such statement may be relied upon by any prospective assignee of Landlord, any mortgagee or prospective mortgagee of the Building, any prospective assignee of

any such mortgagee, or any prospective and/or subsequent purchaser or transferee of all or a part of Landlord’s interest in the Property, the Office Section or the Building, or any other person having an interest therein. Tenant shall execute and deliver whatever additional instruments may reasonably be required for such purposes. Tenant’s failure to deliver any of the foregoing instruments or the statement within twenty (20) days of Landlord’s request therefor in writing shall be deemed to be an acknowledgement that the statements contained therein are true.

ARTICLE 21.
SUBORDINATION

This Lease and all rights of Tenant hereunder are subject and subordinate to any mortgage or mortgages, blanket or otherwise, made by Landlord and which do now or may hereafter affect the Property or the Building; and to any and all renewals, modifications, consolidations, replacements and extensions thereof, and to any ground or other lease, or similar instrument now or hereafter placed against the Building; provided that the foregoing subordination shall only be effective as to a mortgagee that has offered to enter into a commercially reasonable subordination, non-disturbance and attornment agreement with Tenant (“SNDA”), and does in fact enter into a SNDA with Tenant if Tenant accepts such offer, under the terms of which (in addition to other commercially reasonable provisions) such Mortgagee shall agree that so long as Tenant is not in default beyond applicable periods of notice and cure of its obligations under this Lease, Tenant’s occupancy under, on and subject to the terms hereof shall not be disturbed. Landlord represents and warrants that as of the date of execution of this Lease, there is no mortgage on the Building or the Property. Tenant shall upon demand at any time or times execute, acknowledge and deliver to Landlord any and all instruments that may be reasonably necessary to subordinate this Lease and all rights of Tenant hereunder to any such mortgage or mortgages or to confirm or evidence such subordination subject to the terms of the SNDA. Each of the parties shall bear its own costs in connection with the subordination and the SNDA. Tenant covenants and agrees, in the event any proceedings are brought for the foreclosure of any mortgage with respect to which it has been delivered a SNDA, to attorn to the purchaser upon any such foreclosure sale if so requested to do by such purchaser, and to recognize such purchaser as the Landlord under this Lease. Tenant agrees to execute and deliver at any time and from time-to-time, upon the request of Landlord or of any holder of such mortgage or of such purchaser, any instrument which may be necessary or appropriate, in the reasonable judgment of the requesting party, in any such foreclosure proceeding or otherwise to evidence such attornment. Tenant waives the provisions of any statute or rule of law, now or hereafter in effect, which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease, or the obligations of Tenant hereunder in the event any such foreclosure proceeding is brought, prosecuted or completed. Tenant and Landlord further agree that if so requested by any mortgagee of Landlord, this Lease shall be made superior to any such mortgage and that they will execute such documents as may be required by such mortgagee to effect the superiority of this Lease to such mortgage.

Following the execution of this Lease, Landlord shall request and use reasonable efforts to obtain from the DOT a recognition agreement, on commercially reasonable terms, pursuant to which the DOT agrees that so long as Tenant is not in default beyond applicable periods of notice and cure of its obligations under this Lease, Tenant’s occupancy under, on and subject to the terms hereof shall not be disturbed in the event of a termination of the Underlying Lease.

ARTICLE 22.
CERTAIN RIGHTS RESERVED BY LANDLORD

Landlord shall have the following rights (but not obligations), each of which Landlord may exercise without notice to Tenant and without liability to Tenant for damage or injury to property, person or business on account of the exercise thereof, and the exercise of any such rights shall not be deemed to constitute an eviction or disturbance of Tenant’s use or possession of the Premises, and shall not give rise to any claim for set-off or abatement of Rent or any other claim:

(i) To change the Building’s name or street address upon not less than one hundred eighty (180) days prior written notice, in which event, Landlord shall reimburse Tenant for all of Tenant’s costs of the type reasonably and customarily incurred by a tenant in connection with changing such name or address on Tenant’s stationary and other office supplies.

(ii) To install, affix and maintain any and all signs on the exterior and on the interior of the Building (other than within the Premises).

(iii) Provided that reasonable access to the Premises shall be maintained and the business of Tenant shall not be interfered with or disrupted unreasonably, to rearrange, relocate, enlarge, reduce, close or change corridors, elevators, stairs, lavatories, doors, lobbies, exits or entrances in or to the Building and to decorate and to make repairs, alterations, additions and improvements, structural or otherwise, in or to the Building or any part thereof, including the Premises, and may erect scaffolding and other structures reasonably required by the character of the work to be performed, and during such operations may upon reasonable notice enter upon the Premises and take into and upon or through any part of the Building, including the Premises, all materials that may be required to make such repairs, alterations, improvements, or additions, and in that connection Landlord may temporarily close public entry ways, other public spaces, stairways, corridors or connecting structures and interrupt or temporarily suspend any services or facilities agreed to be furnished by Landlord all, subject to the provisions of this clause, without the same constituting an eviction of Tenant in whole or in part, and without abatement of Rent by reason of loss or interruption of the business of Tenant or otherwise, and without in any manner rendering Landlord liable for damages or relieving Tenant from performance of Tenant’s obligations under this Lease. Landlord may at its option make any repairs, alterations, improvements and additions in and about the Building and upon reasonable notice in or about the Premises during ordinary business hours and, if Tenant desires to have such work done during other than business hours, Tenant shall pay all overtime and additional expenses resulting therefrom. Landlord’s entry into the Premises shall be accomplished in a manner to minimize interference with the Tenant’s business but such commitment shall not require Landlord to perform such work during other than ordinary business hours.

(iv) To furnish door keys for the entry door(s) in the Premises at the commencement of this Lease and to retain at all times, and to use in appropriate instances, keys to all doors within and into the Premises and Tenant shall be obligated

should it elect to change the manner in which its Premises are secured to provide Landlord with duplicates of keys, entry cards and with combinations or passwords necessary to allow Landlord and those furnishing services to the Premises in accordance with the terms and conditions of this Lease to access the Premises for such purposes as may be permitted under this Lease. Upon the expiration of the Term or of Tenant’s right of possession, Tenant shall return all keys to Landlord and shall disclose to Landlord the combination of any safes, cabinets or vaults left in the Premises.

(v) To approve all window coverings used in the Building which approval shall not be unreasonably withheld, conditioned or delayed, it being understood that window coverings which are visible from outside the Premises may be subject to a standard of uniformity imposed by the Landlord in its reasonable discretion.

(vi) To approve the weight, size and location of safes, vaults and other heavy equipment and articles in and about the Premises and the Building so as not to exceed the legal live load per square foot designated by the structural engineers for the Building, and to require all such items and furniture and similar items to be moved into or out of the Building and Premises only at such times and in such manner as Landlord shall direct in writing. Tenant shall not install or operate machinery or any mechanical devices of a nature not directly related to Tenant’s ordinary use of the Premises without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed. Movement of Tenant’s property into or out of the Building or the Premises and within the Building are entirely at the risk and responsibility of Tenant, and Landlord reserves the right to require permits before allowing any property to be moved into or out of the Building or the Premises.

(vii) To establish reasonable security policies and other controls for the purpose of regulating all property and packages, both personal and otherwise, to be moved into or out of the Building and Premises and all persons using the Building both during and after normal office hours, provided such policies and other controls do not unreasonably interfere with Tenant’s security system and security protocol set forth herein. Without limiting the generality of the foregoing, Landlord may require all persons entering or leaving the Building during such hours as Landlord may from time to time reasonably determine to identify themselves to security personnel by registration or otherwise in accordance with Building security controls, and to establish their right to enter or leave in accordance with the provisions of applicable rules and regulations adopted by Landlord. Landlord shall not be liable in damages for any error with respect to exclusion from the Building of any person. In case of fire, casualty, invasion, insurrection, mob, riot, civil disorder, public excitement or other commotion, or threat thereof, Landlord reserves the right, in its reasonable discretion, to limit or prevent access to the Building during the continuance of the same, shut down elevator service, activate elevator emergency controls or otherwise take such action or preventive measures deemed reasonably necessary by Landlord for the safety or security of the tenants or other occupants of the Building or the protection of the Building and the property in the Building. Tenant agrees to cooperate with any reasonable safety or security program developed by Landlord.

(viii) To reasonably regulate delivery and service of supplies and the usage of the loading docks, receiving areas and freight elevators.

(ix) To show the Premises to prospective tenants at reasonable times in the last eighteen (18) months of the Term (as the same may have been extended as set forth in ARTICLE 41), and, if vacated or abandoned, to show the Premises at any time, and to decorate, remodel, repair, alter or otherwise prepare the Premises for re- occupancy.

(x) To erect, use and maintain pipes, ducts, wiring and conduits, and appurtenances thereto, in and through the Premises at reasonable locations.

(xi) To enter the Premises at any reasonable time to inspect the Premises upon twenty-four (24) hours prior written, telephone or fax notice to Tenant except in an emergency, for the purpose of inspecting or making repairs to the Premises or responding to any emergency condition, and Landlord shall also have the right to make access available at all reasonable hours, upon twenty-four (24) hours prior written notice to Tenant except in an emergency, to prospective or existing mortgagees, purchasers or tenants of all or any part of the Property.

(xii) To grant to any person or to reserve unto itself the exclusive right to conduct any business or render any service in the Building. If Landlord elects to make available to tenants in the Building any services or supplies, or arranges a master contract therefor, Tenant agrees to obtain its requirements, if any, therefor from Landlord or under any such contract, provided that the charges therefor are reasonable.

ARTICLE 23.
RULES AND REGULATIONS

Tenant agrees to observe the rules and regulations for the Building attached hereto as Exhibit C and made a part hereof. Landlord shall have the right from time to time to prescribe additional rules and regulations which, in its judgment, may be desirable for the use, entry, operation and management of the Premises, the Office Section and the Building, each of which rules and regulations and any amendments thereto shall become a part of this Lease. Tenant shall comply with all such rules and regulations; provided, however, that such rules and regulations shall not contradict or abrogate any right or privilege herein expressly granted to Tenant.

ARTICLE 24.
LANDLORD’S REMEDIES

The following shall each be an “Event of Default” under this Lease: If Tenant shall fail to pay the Rent or any installment thereof within five (5) business days after the date due or shall fail to pay, within five (5) business days after written notice of such failure is given to Tenant, any other sum required to be paid by Tenant under this Lease or under the terms of any other agreement between Landlord and Tenant; or if the interest of Tenant in this Lease shall be levied on under execution or other legal process; or if any voluntary petition in bankruptcy or for corporate re-organization or any similar relief shall be filed by Tenant; or if any involuntary petition in bankruptcy shall be filed against Tenant under any federal or state bankruptcy or

insolvency act and shall not have been dismissed within ninety (90) days from the filing thereof; or if a receiver shall be appointed for Tenant or any of the property of Tenant by any court and such receiver shall not have been dismissed within ninety (90) days from the date of his appointment; or if Tenant shall make an assignment for the benefit of creditors; or if Tenant shall admit in writing Tenant’s inability to meet Tenant’s debts as they mature; or if Tenant shall have misrepresented or breached a warranty to Landlord set forth in clause S of Section 32 of this Lease for which no cure period is applicable under Section 32.S; or if any event has occurred which is specified as an Event of Default under this Lease; or if Tenant shall fail to observe or perform any of the other covenants or conditions in this Lease which Tenant is required to observe and perform and such default shall continue for thirty (30) days after written notice to Tenant (or if such default is curable and shall reasonably require more than thirty (30) days to cure, if Tenant shall fail to commence to cure said default within thirty (30) days after notice thereof and/or fail to continuously prosecute the curing of the same to completion with due diligence) then Landlord may treat the occurrence of any one or more of the foregoing events as a breach of this Lease. If an Event of Default occurs, Landlord at its option may, without additional notice or any demand of any kind to Tenant or any other person, have any one or more of the following described remedies in addition to all other rights and remedies provided at law or in equity or elsewhere in this Lease:

(i) Landlord may terminate this Lease and the Term created hereby at any time after the occurrence of any such Event of Default and shall give Tenant written notice of Landlord’s election to do so and the effective date thereof (the “Effective Date”), in which event Landlord may forthwith repossess the Premises in accordance with applicable law and shall be entitled to recover,

(a) forthwith as liquidated damages, in addition to any other sums or liabilities under this Lease due to Landlord and damages for which Tenant may be liable, a sum of money equal to the present value (such present value to be computed on the basis of a per annum discount rate equal to the effective annual yield on U.S. Treasury obligations which could be purchased on the business day next succeeding the Effective Date (or if Landlord has elected to first avail itself of the remedy provided in subclause 24(i)(b) below, the date as of which it notifies Tenant that it is electing the remedy set forth in this subclause 24(i)(a)) and mature closest to the Termination Date as determined as if this Lease had not been terminated for a default hereunder) of the Rent provided to be paid by Tenant for the balance of the Term over the present value of the fair market rental value of the Premises, after deduction from the present value of such fair market rental value of all anticipated expenses of reletting. Should the present value of the fair market rental value of the Premises, after deduction of all anticipated expenses of reletting, for the balance of the Term exceed the present value of the Rent provided to be paid by Tenant for the balance of the Term, Landlord shall have no obligation to pay to Tenant the excess or any part thereof or to credit such excess or any part thereof against any other sums or damages for which Tenant may be liable to Landlord, and unless and until such time as Landlord elects to avail itself of the remedy set forth in this subclause 24(i)(a).

(b) in addition to any other sums or damages for which Tenant may otherwise be liable to Landlord, a sum of money equal to amounts due at the Effective Date and to recover from time to time from Tenant, and Tenant shall remain liable for, all Rent which

would have thereafter been due but for such termination as and when the same would have become due (or after the same would have become due) had such termination not occurred by reason of default by Tenant, and any other sums thereafter accruing as they would have become due under this Lease during the period from the Effective Date to the Termination Date and at any time while Landlord is pursuing its rights hereunder, Landlord may invoke its rights to liquidated damages for the balance of the term as provided in subclause 24(i)(a) above.

Landlord may, but shall be under no obligation to, except as required by law, relet the Premises or any part thereof for the account of Tenant, for such rent, from time to time (which may be for a term extending beyond the Term of this Lease), and upon such terms as Landlord in Landlord’s sole discretion shall determine and Landlord shall have no obligation to accept any proposal made by third parties nor shall Landlord be required to accept any tenant offered by Tenant or to observe any instructions given by Tenant relative to such reletting. Also at any time prior to Landlord exercising rights under subclause 24(i)(a) above, Landlord may change the locks or other entry devices of the Premises and make repairs, alterations and additions in or to the Premises and redecorate same to the extent deemed by Landlord necessary or desirable, and Tenant shall upon written demand pay the cost thereof together with, if Landlord successfully relets the Premises or any part thereof, Landlord’s expenses of reletting, including without limitation, brokerage commissions payable to Landlord’s agent or to others.

Landlord may collect the rents from any such reletting and apply the same to the payment of expenses of reentry, redecoration, repair and alterations and the expenses of reletting and the excess or residue remaining to the payment of Rent and other sums in this Lease provided to be paid by Tenant under subclause 24(i)(b) above after the date of any such reletting, and any such excess or residue shall operate only as an offsetting credit against the amount of Rent and other sums due and owing with respect to periods after the date of such reletting. For purposes of clarity, in no event shall Tenant be entitled to a credit on its indebtedness to Landlord with respect to prior periods or a refund of amounts accelerated pursuant to subclause 24(i)(a) if Landlord relets the Premises or any part thereof. No such reentry, repossession, repairs, alterations, additions or reletting pursuant to this ARTICLE shall operate to release Tenant in whole or in part from any of Tenant’s obligations hereunder, and if Landlord effects any such reletting, Landlord may, at any time and from time to time, with respect to periods prior to the period with respect to which Landlord avails itself of the remedy set forth in subclause 24(i)(a) above (and Tenant’s payment of the amount required thereby) xxx and recover judgment for any deficiencies from time to time remaining after the application from time to time of the proceeds of any such reletting.

(ii) Landlord, without thereby waiving default or breach, may cure the same for the account and at the expense of Tenant, without notice in a case of emergency threatening life or property, as determined by Landlord in its sole discretion, or in case of correction of a dangerous or hazardous condition threatening life or property, and in any other case if such default or breach is or becomes an Event of Default or continues for five (5) days after the Landlord gives written notice of intention to cure. Bills for any expense incurred by Landlord in connection with any such performance by Landlord shall be for the account of Tenant, and shall be due and payable within thirty (30) days

after Tenant receives said bills, and if not paid when due, the amounts thereof shall become immediately due and payable as Additional Rent under this Lease.

ARTICLE 25.
EXPENSES OF ENFORCEMENT

Tenant shall pay upon demand all Landlord’s reasonable costs, charges and expenses including the fees and out-of-pocket expenses of counsel, agents and others retained by Landlord incurred in enforcing Tenant’s obligations hereunder following the occurrence of a default or breach which continues beyond any applicable grace or cure periods.

ARTICLE 26.
COVENANT OF QUIET ENJOYMENT

Landlord covenants that Tenant, on paying the Rent, charges for services and other payments herein reserved and on keeping, observing and performing, within applicable periods of notice, cure and grace, all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant to be kept, observed and performed shall, during the Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions and agreements hereof, without hindrance or ejection by any persons lawfully claiming by, through or under Landlord, the foregoing covenant of quiet enjoyment being in lieu of any other covenant, expressed or implied.

ARTICLE 27.
LETTER OF CREDIT

27.01 General Provisions. Not later than the date on which Tenant commences its Initial Alterations, Tenant shall deliver to Landlord, as collateral for the full performance by Tenant of all of its obligations under this Lease and for all losses and damages Landlord may suffer as a result of Tenant’s failure to comply with one or more provisions of this Lease, a Letter of Credit (hereinafter defined) substantially in the form of Exhibit F and containing the terms required herein, in the face amount of the Letter of Credit Amount, naming Landlord as beneficiary.

“Letter of Credit” shall mean a clean, irrevocable, non-documentary and unconditional letter of credit, permitting multiple and partial draws thereon, and otherwise in form acceptable to Landlord in its sole, reasonable discretion issued by and drawable upon a commercial bank (the “Issuing Bank”), which is satisfactory to Landlord and which satisfies both the Minimum Rating Agency Threshold (as hereinafter defined) and the Minimum Capital Threshold (as hereinafter defined). 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 Xxxxx’x 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 $2,000,000,000.

If, at any time or from time to time, Landlord reasonably determines that an Issuing Bank (i) no longer satisfies the Minimum Rating Agency Threshold, (ii) no longer satisfies the Minimum Capital Threshold, (iii) has been seized or closed by the Federal Reserve Board, the Federal Deposit Insurance Corporation, the Office of the Comptroller of the Currency, or another governmental or regulatory agency or authority, (iv) has become insolvent or its financial condition is such that in Landlord’s reasonable judgment, the Issuing Bank may be unable to honor a draw on the Letter of Credit, or (v) is unwilling or unable to honor the Letter of Credit or to perform its obligations to honor a draw upon the Letter of Credit, then within ten (10) days after demand, Tenant shall deliver to Landlord a replacement Letter of Credit, issued by a replacement Issuing Bank which satisfies the Minimum Rating Agency Threshold and the Minimum Capital Threshold and is otherwise satisfactory to Landlord in its discretion.

Tenant shall cause the Letter of Credit to be continuously maintained in effect (whether through replacement, renewal or extension) in the Letter of Credit Amount through the date (the “Final LC Expiration Date”) that is sixty (60) days after the scheduled expiration date of the Term or any renewal Term. If the Letter of Credit held by Landlord expires earlier than the Final LC Expiration Date (whether by reason of a stated expiration date or a notice of termination or non-renewal given by the issuing bank), Tenant shall deliver a new Letter of Credit or certificate of renewal or extension (a “Renewal or Replacement LC”) to Landlord not later than sixty (60) days prior to the expiration date of the Letter of Credit then held by Landlord. Any Renewal or Replacement LC shall comply with all of the provisions of this ARTICLE 27, shall be irrevocable, transferable and shall remain in effect (or be automatically renewable) through the Final LC Expiration Date upon the same terms as the expiring Letter of Credit or such other terms as may be acceptable to Landlord in its sole, reasonable discretion.

27.02 Drawings under Letter of Credit. Upon Tenant’s failure to comply with one or more provisions of this Lease which continues beyond applicable periods of notice and cure, or as otherwise specifically agreed by Landlord and Tenant pursuant to this Lease or any amendment hereof, Landlord may, without prejudice to any other remedy provided in this Lease or by Law, draw on the Letter of Credit and use all or part of the proceeds to (a) satisfy any amounts due to Landlord from Tenant, and (b) satisfy any other damage, injury, expense or liability caused by Tenant’s failure to so comply. In addition, if Tenant fails to furnish a Renewal or Replacement LC complying with all of the provisions of this ARTICLE 27 at least sixty (60) days prior to the stated expiration date of the Letter of Credit then held by Landlord, Landlord may draw upon such Letter of Credit and hold the proceeds thereof (and such proceeds need not be segregated) in accordance with the terms of this ARTICLE 27 (the “LC Proceeds Account”).

27.03 Use of Proceeds by Landlord. Subject to Section 27.02, the proceeds of the Letter of Credit shall constitute Landlord’s sole and separate property (and not Tenant’s property or the property of Tenant’s bankruptcy estate) and Landlord may immediately upon any draw (and without notice to Tenant) apply or offset the proceeds of the Letter of Credit: (a) against any Rent or other amount payable by Tenant under this Lease that is not paid when due; (b) against all losses and damages that Landlord has suffered; (c) against any costs incurred by Landlord in connection with this Lease (including attorneys fees); and (d) against any other amount that Landlord is owed by reason of Landlord’s exercise of its remedies for Tenant default under this Lease. Landlord agrees to return the Original Letter of Credit or any Renewal or Replacement LC pay to Tenant, or at Tenant’s written direction, the Issuing Bank or pay within thirty (30)

days after the Final LC Expiration Date the amount of any proceeds of the Letter of Credit received by Landlord and not applied as allowed above; provided, that if prior to the Final LC Expiration Date a voluntary petition is filed by Tenant, or an involuntary petition is filed against Tenant by any of Tenant’s creditors, under the Federal Bankruptcy Code, then Landlord shall not be obligated to make such payment in the amount of the unused Letter of Credit proceeds until either all preference issues relating to payments under this Lease have been resolved in such bankruptcy or reorganization case or such bankruptcy or reorganization case has been dismissed, in each case pursuant to a final court order not subject to appeal or any stay pending appeal.

27.04 Additional Covenants of Tenant. If, as result of any application or use by Landlord of all or any part of the Letter of Credit, the amount of the Letter of Credit shall be less than the Letter of Credit Amount, Tenant shall, within five (5) business days thereafter, provide Landlord with additional letter(s) of credit in an amount equal to the deficiency (or a replacement letter of credit in the total Letter of Credit Amount), and any such additional (or replacement) letter of credit shall comply with all of the provisions of this ARTICLE 27, and if Tenant fails to comply with the foregoing, notwithstanding anything to the contrary contained in this Lease, the same shall constitute an Event of Default by Tenant. Tenant further covenants and warrants that it will neither assign nor encumber the Letter of Credit or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance.

27.05 Nature of Letter of Credit. Landlord and Tenant (a) acknowledge and agree that in no event or circumstance shall the Letter of Credit or any renewal thereof or substitute therefor or any proceeds thereof (including the LC Proceeds Account) be deemed to be or treated as a “security deposit” under any Law applicable to security deposits in the commercial context (“Security Deposit Laws”), (b) acknowledge and agree that the Letter of Credit (including any renewal thereof or substitute therefor or any proceeds thereof) is not intended to serve as a security deposit, and the Security Deposit Laws shall have no applicability or relevancy thereto, and (c) waive any and all rights, duties and obligations either party may now or, in the future, will have relating to or arising from the Security Deposit Laws.

ARTICLE 28.
REAL ESTATE BROKER

The Tenant represents that Tenant has dealt with (and only with) the Broker specified in ARTICLE 1 hereof as broker in connection with this Lease, and that insofar as Tenant knows, no other broker negotiated this Lease or is entitled to any commission in connection therewith. Tenant agrees to indemnify, defend and hold harmless Landlord its employees and agents from and against any claims made by any broker or finder other than the Broker named above for a commission or fee in connection with this Lease or any sublease hereunder, but nothing herein shall be construed as permitting any such sublease, provided that Landlord has not in fact retained such broker or finder. Landlord agrees to indemnify, defend and hold harmless Tenant, its employees and agents from and against any claims made by any broker or finder named above for a commission or fee in connection with this Lease, provided Tenant has not in fact retained such broker or finder and, in addition, Landlord shall pay the fees of the Broker(s) named in ARTICLE 1 of this Lease.

ARTICLE 29.
NOTICE TO MORTGAGEE AND GROUND LESSOR

After receiving notice from any person, firm or other entity that it holds a mortgage which includes the Premises, the Building or the Office Section as part of the mortgaged premises, or that it is the ground lessor under a ground lease (which term shall include the Underlying Lease and the Sublease (as such terms are defined in Section 32U of this Lease)) with Landlord, as ground lessee, which includes the Premises, the Building or the Office Section as part of the demised premises, no notice of default from Tenant to Landlord shall be effective unless and until a copy of the same is given to such holder or ground lessor, and the timely curing of any of Landlord’s defaults by such holder or ground lessor shall be treated as performance by Landlord. Such holder or ground lessor shall be given such reasonable time as may be necessary to effect such cure or to foreclose the mortgage or terminate the ground lease, as the case may be. For the purposes of ARTICLE 21, this ARTICLE 29, ARTICLE 30 and ARTICLE 33, the term “mortgage” includes a mortgage on a leasehold interest of Landlord (but not one on Tenant’s leasehold interest).

ARTICLE 30.
ASSIGNMENT OF RENTS

With reference to any assignment by Landlord of Landlord’s interest in this Lease, or the rents payable hereunder, conditional in nature or otherwise, which assignment is made to the holder of a mortgage or ground lease (which term shall include the Underlying Lease and the Sublease) on property which includes the Premises, the Building or the Office Section, Tenant agrees:

(i) that the execution thereof by Landlord, and the acceptance thereof by the holder of such mortgage, or the ground lessor, shall never be treated as an assumption by such holder or ground lessor of any of the obligations of Landlord hereunder, unless such holder, or ground lessor, shall, by notice sent to Tenant, specifically otherwise elect; and

(ii) that, except as aforesaid, such holder or ground lessor shall be treated as having assumed Landlord’s obligations hereunder only upon a foreclosure of such holder’s mortgage and the taking of possession of the Premises, or in the case of a ground lessor, the assumption of Landlord’s position hereunder by such ground lessor. In no event shall the acquisition of title to the Building and the land on which the same is located by a purchaser which, simultaneously therewith, leases the entire Building or such land back to the seller thereof be treated as an assumption, by operation of law or otherwise, of Landlord’s obligations hereunder, but Tenant shall look solely to such seller-lessee, and its successors from time to time in title, for performance of Landlord’s obligations hereunder. In any such event, this Lease shall be subject and subordinate to the lease to such seller. For all purposes, such seller-lessee, and its successors in title, shall be the landlord hereunder unless and until Landlord’s position shall have been assumed by such purchaser-lessor.

ARTICLE 31.
PERSONAL PROPERTY TAXES

Furthermore, if Landlord shall not have substantially completed Landlord’s Work with respect to restroom renovation with respect to the Initial Premises by September 14, 2014, then Tenant shall be entitled to a credit, for each day from September 1, 2014 to the date of such substantial completion, against Base Rent equal to one (1) day of Base Rent applicable to any floor of Tower IV (based on rentable square feet on that floor) with respect to which the Landlord’s Work thereon shall not have been substantially completed. In addition, if Tenant adds space to the Initial Premises and as a result of such addition, Tenant is leasing more than 50% of a floor of a Tower, Landlord shall renovate the restrooms on such floor as contemplated by Exhibit B-2, and if Landlord shall not have substantially completed such restroom renovation on such floor by the date which is one hundred twenty (120) days following the date on which the Landlord delivers the space to Tenant that results in Tenant being the tenant of more than 50% of such floor, then Tenant shall be entitled to a credit, for each day following the end of such one hundred twenty (120) day period to the date of such substantial completion, against Base Rent due under this Lease equal to one (1) day of Base Rent applicable to the additional space on such floor which resulted in Landlord’s obligation.

ARTICLE 38.
TENANT IMPROVEMENT ALLOWANCE

Subject to the terms of this Section 38 set forth below, there shall be paid by the Landlord as the Landlord’s contribution toward Tenant’s Initial Alterations, the sum (“Allowance”) of

$7,191,555.84, based upon a contribution of $68.04 per rentable square foot for 105,696 rentable square feet in the Initial Premises. Tenant shall submit to Landlord Tenant’s good faith estimate (“Qualified Cost Estimate”) of the Qualified Costs (hereinafter defined) to be incurred by Tenant in connection with its move to and the construction of Initial Alterations in the Premises. Installments of the Allowance shall be payable in accordance with the procedures set forth below. Installments of the Allowance, which shall in no event exceed in the aggregate the amount of the Allowance, shall be paid to Tenant (or, at Landlord’s option if Landlord reasonably determines that Tenant is not paying its contractors and such failure to pay may give rise to a lien against the Building, to the order of the contractor that performed the work set forth in the respective invoices) or, at Tenant’s option to Tenant’s contractors, with respect to Qualified Costs theretofore incurred by Tenant (and not theretofore paid to Tenant or which were Tenant’s responsibility as set forth in this Article 38) for which Tenant has submitted a requisition consisting of, (i) in the case of other than costs incurred under architectural and engineering contracts (collectively “Professional Services Contracts”) or under construction contracts, such as furniture or moving or professional fees that are contracted for by Tenant separate from construction and Professional Services Contracts, paid invoices, (ii) in the case of Professional Services Contracts, invoices, and (iii) in the case of construction costs (a) an application for payment and sworn statement of a contractor performing general contracting work in the Premises substantially in the form of AIA Document G-702 covering all work for which disbursement is to be made to a date specified therein which is part of the construction contract; (b) a certification from an AIA architect substantially in the form of the Architect’s Certificate for Payment which is located on AIA Document G702, Application and Certificate of Payment; (c) contractor’s, project managers and subcontractor’s waivers of liens which shall cover all applicable items of Qualified Costs under such construction contracts for which disbursement is being requested and any other statements and forms required for compliance with the mechanics’ lien laws of the Commonwealth of Massachusetts, together with invoices with respect to such Qualified Costs and such other supporting data as Landlord or Landlord’s Mortgagee may reasonably require; (iv) a cost breakdown for each trade or subcontractor performing the work included in Qualified Costs for which a request for disbursement under such construction contracts is being made; (v) copies of all construction contracts for the such Alterations, together with copies of all change orders, if any; and (iii) a request to disburse from Tenant containing an acknowledgement by Tenant of the work done and a good faith estimate of the cost to complete the Initial Alterations to the Premises. Upon completion of the Initial Alterations, and as part of the requisition for final disbursement of the Allowance for hard construction costs, Tenant shall furnish Landlord with: (1) general contractor and architect’s completion affidavits, (2) full and final waivers of lien, (3) receipted bills covering all labor and materials expended and used, (4) as-built plans of the Alterations, and (5) the certification of Tenant’s architect to the Landlord that, based on on-site observation and the data comprising the application for disbursement, to the best of the architect’s knowledge, information and belief, the Alterations have progressed as indicated in the application, the quality of the Alterations is in accordance with the construction contract documents and the contractor is entitled to; payment of the amount certified in the application. Notwithstanding the foregoing, if the Qualified Cost Estimate exceeds the Allowance, Tenant shall be entitled to payments with respect to any requisition in accordance with the terms hereof except that each individual disbursement of the Allowance by Landlord shall be in the same ratio to the amount properly requisitioned as the Allowance bears to the Adjusted Qualified Cost Estimate (hereinafter defined). “Adjusted

Qualified Cost Estimate” means the Qualified Cost Estimate reduced by any amount paid prior to the date of computing the Adjusted Qualified cost Estimate by Tenant directly to a contractor, professional or supplier with respect to the cost of an item that had been included in the Qualified Cost Estimate, but with respect to which Tenant will not be submitting a requisition (and for which Landlord will not make any payment with respect to the Allowance). Furthermore, the amount of any installment of the Allowance otherwise payable shall be reduced by the amount of any retainage applicable to the Qualified Costs (proportionately if an individual disbursement is reduced as set forth in the immediately preceding sentence) with respect to which the disbursement is being requested, but such retainage shall be payable as part of the final draw when all requirements set forth for such disbursement have been met). In no event shall Landlord be required to disburse any installment of the Allowance more than twice in any calendar month and in no event will Landlord be obligated to disburse an amount which is less than $50,000 (other than the final disbursement on account of the Allowance). Notwithstanding anything herein to the contrary, Landlord shall not be obligated to disburse any portion of the Allowance during the continuance of an uncured default under this Lease, and Landlord’s obligation to disburse shall only resume when and if such default is curable and is, in fact, cured. Time is of the essence with respect to the time periods set forth in this Section 38.

For purposes hereof, “Qualified Costs” shall mean actual costs for (a) preparation of drawings and other expenses incurred in connection with design and construction, including without limitation permit fees and costs of labor and materials, (b) construction of the Premises in accordance with the plans and specifications approved in accordance with ARTICLE 10, (c) wiring and cabling in the Premises (d) architectural, engineering, construction management, project management and other professional fees relating to design and construction of the Premises and the negotiation of this Lease, (e) costs for the procurement of furniture, fixtures and equipment in connection with this Lease, (f) telephone data, equipment, audio visual equipment, security systems and special power distribution (g) moving and delivery costs, (h) skylights and (i) a roof deck on the roof of Tower IV, U) interconnecting staircases between floors in the Premises, and (k) all other hard and soft costs related to the Tenant’s Alterations and moving expenses associated with the space with respect to which the Allowance for such Qualified Costs is being provided.

Notwithstanding the foregoing, if, as of June 15, 2015, the amount paid or payable (by reason of requisitions) by Landlord with respect to the Allowance is less than the Allowance, Landlord shall apply an amount equal the difference between the amount theretofore requisitioned by Tenant and the Allowance to Base Rent next coming due under this Lease; provided however, Landlord shall have no obligation to apply such amount to Base Rent if Tenant is in default of its obligations under this Lease unless and until such application would cure all defaults of Tenant in full.

Landlord shall pay the portion of the Allowance related to a requisition as is to be paid by Landlord under this Article 38 not later than thirty (30) days following the Landlord’s approval of the applicable requisition package. Landlord shall have a review period of fifteen (15) business days following the submission of a requisition package to object to the submission as not being in compliance with this Article 38 and if Landlord does not object to the submission within such period, the submission shall be deemed approved. If Landlord shall object to a requisition package, Tenant shall resubmit as necessary to comply with this Article 38 and the

process for approval shall begin again. If Landlord shall fail to pay by the date due hereunder the amount to be paid by Landlord in accordance with this Article 38 for thirty (30) days following approval or deemed approval of the requisition package, upon five (5) days prior written notice thereof from Tenant to Landlord of such failure, Tenant may offset against Base Rent next payable by Tenant to Landlord under this Lease, the amount which was not paid by the end of such thirty (30) day notice period together with interest thereon at the rate specified in Section 32.B of this Lease from the end of such thirty (30) day period until the date on which such amount with interest is offset against such Base Rent or otherwise paid by Landlord to Tenant.

ARTICLE 39.
FINANCIAL STATEMENTS

Tenant shall furnish to Landlord annually within thirty (30) days after Landlord’s request therefor in connection with any bona fide potential sale or financing of the Building, Tenant’s most recent annual statement, certified by a responsible financial officer of Tenant. Tenant agrees that Landlord may deliver a copy of such statements to its mortgagee or ground lessor or a potential purchaser of Landlord’s interest in the Premises, but otherwise, Landlord shall treat such statements and information contained therein as confidential; provided, however, Landlord may release such statements and information if and to the extent required by a court of competent jurisdiction or if in the opinion of Landlord’s counsel, the information contained in such statements and information is required to be disclosed under applicable law following not less than ten (10) business days’ notice to Tenant unless otherwise required by applicable law.

ARTICLE 41.
OPTION TO EXTEND LEASE

Tenant shall have the right to extend the Term of this Lease for two (2) successive five (5) year periods, each such right of Tenant to be conditioned upon (a) this Lease at the time of election being in full force and effect and Tenant not then being in default under this Lease beyond any applicable notice and cure period, such extension period to commence upon the expiration of the original Term of this Lease, (b) as to the second option, the first option having been exercised. Each option may be exercised for all or a portion, but not less than 70%, of the

Premises as the same is constituted at the date the option is exercised; provided, however, any contiguous portion of the Premises on any floor of any Tower with respect to which Tenant does not exercise an option to extend (each, a “Non-Extended Space”) (a) shall be not less than 5,000 contiguous rentable square feet on any one floor of any one Tower and (b) shall meet the Window Line Criterion (hereinafter defined) and (c) shall be accessible by a corridor that is consistent with corridor layouts in comparable first class office towers. Tenant shall be responsible for the cost of separately demising the remaining Premises (demising walls erected and Building systems separated from the space relinquished). The “Window Line Criterion” shall mean that the Non-Extended Space satisfies any one of the following conditions:

(i) The window lines (exterior and atrium facing) are comparable to the window lines (exterior and atrium facing) of any other leased space in the Office Section of comparable size;

(ii) The window lines (exterior and atrium facing) are substantially proportionate to the window lines (exterior and atrium facing) in the space on the floor that they is being retained;

(iii) The window line is, in the view of the Landlord’s Office Section brokers, marketable at rates consistent with the rates for other space of the Office Section; or

(iv) The window lines (exterior and atrium facing) are substantially proportionate to the window lines (exterior and atrium facing) of any other leased space in the Office Section.

A right of extension shall be exercised, if at all, by written notice to Landlord given at least eighteen (18) months, but not more than twenty-four (24) months prior to the expiration of the then Term of this Lease and such notice must designate the portion of the then Premises, if less than all, with respect to which the extension is being exercised. If a notice is given in compliance with the provisions hereof, this Lease shall, thereupon, be extended for the applicable extension period, subject to the terms of this ARTICLE 41, without the need for any further instrument to be executed (but either party shall execute such a confirmatory instrument upon the request of the other); and if no such notice is given, then Tenant’s right of extension shall be null and void. All of the terms, conditions and provisions of this Lease shall be applicable to any extension of the Term hereof, as if the termination date of the extension period were the date originally set forth herein for the expiration of the Term, except that (i) the exercised right of extension shall be of no further force or effect, so that there shall be no further right of extension with respect thereto, (ii) the Base Rent per square foot during the extension period shall be 95% of the Fair Market Rent (as hereinafter defined); and (iii) the Premises demised under this Lease during the extension period shall be the Premises set forth in Tenant’s notice of extension (which may not be less than seventy percent (70%) of the Premises demised under this Lease at the time the notice of extension is given, as described above) and Tenant’s Proportionate Tax Share and Tenant’s Proportionate Expense Share shall be proportionately adjusted, if necessary to reflect the reduced size of space included in the Premises.

“Fair Market Rent” for purposes of this ARTICLE 41 shall mean the rent (base rent and additional rent adjusted, if necessary, to reflect the base years to be used for the applicable period) per rentable square foot for similar office space in the Building and in comparable buildings as reasonably located in the City of Boston, (i) without taking into account actual improvements (regardless of who paid for such improvements), or the cost of demolition of the space, and (ii) taking into account (A) the magnitude of any free rent or buildout allowance, (B) length of lease, (C) building amenities, (D) the location and floor levels of the premises, (E) services provided, (F) surrender rights, if any, (G) parking rights and obligations, (H) free rent, tenant allowances or other concessions and (I) all other relevant market factors and (iii) taking into account the brokerage commissions, if any, to be paid in connection with the renewal.

Within thirty (30) days after Tenant’s exercise of the extension option (or, if earlier, within thirty (30) days after Tenant’s request for Landlord’s rental rate, which may be made at any time after the date twenty-two (22) months prior to the then scheduled expiration of the Term and prior to Tenant’s giving its notice exercising the extension option), Landlord shall provide Tenant with its good faith estimate of the Fair Market Rent for the period of the extension. If, within thirty (30) days after Tenant’s receipt of Landlord’s estimate (“Consideration Period”), Tenant shall not have accepted Landlord’s estimate of Fair Market Rent, the parties shall at the request of either party made by notice given within ten (10) days of the end of the Consideration Period, discuss the matter in good faith for thirty (30) days. If within such thirty (30) day period the parties have not agreed on the Fair Market Rent rate in writing, then Landlord and Tenant shall, during the ensuing fifteen (15) days, attempt to agree on an arbitrator not affiliated with either party (and if they are unable to do so, either party may request that the President of the American Arbitration Association in Boston choose an arbitrator, as promptly as possible, meeting the criteria set forth below; provided, however, the parties shall have the right during the ten (10) day period following the end of the fifteen (15) day period to submit the names of not more than two (2) potential arbitrators meeting the said criteria and if the parties or either of them makes such a submission, the choice of the President of the American Arbitration Association shall be made from the list of potential arbitrators so submitted). Such arbitrator shall have a period of thirty (30) days to determine which of Landlord’s estimate of Fair Market Rent or Tenant’s estimate of Fair Market Rent hereunder more closely corresponds to the Fair Market Rent and the estimate of Fair Market Rent which in the judgment of the arbitrator more closely corresponds to the arbitrator’s estimate of Fair Market Rent shall be the Fair Market Rent for purposes hereof and the determination shall be binding upon the parties. The arbitrator must choose either the Fair Market Rent estimate submitted by Landlord or the Fair Market Rent estimate submitted by Tenant. Such arbitrator shall have at least ten (10) years’ experience in the valuation and appraisal of first-class office rents for real estate in the City of Boston, be experienced with leasing transactions exceeding 100,000 square feet within the downtown Boston area, and have no then contractual relationship with either Landlord or Tenant. The expenses of the arbitrator shall be borne equally by the Landlord and the Tenant.

ARTICLE 42.
EXPANSION RIGHTS

42.01 Special Expansion Rights. Exhibit A-1 described certain spaces in Tower IV of the Building of which the Tenant is State Street Bank or an affiliate. Each such space is

designated on Exhibit A-1 as “SSB” and is referred to herein as an “SSB Expansion Space” and such spaces are referred to herein collectively as “SSB Expansion Spaces”. The SSB Expansion Spaces are subject to a lease which terminates on December 31, 2014, if not extended pursuant to its current terms by December 31, 2013. In the event the lease of the SSB Expansion Spaces is not extended pursuant to the terms of the currently existing rights of the tenant thereof to extend either because the tenant of the SSB Expansion Space does not give timely notice of extension or because such tenant provides a waiver of the right to extend prior to December 31, 2013, Landlord shall promptly notify Tenant and Tenant shall have the option to expand the Initial Premises by any or all of the SSB Expansion Spaces (but as to any designated SSB Expansion Space on any one floor of any Tower, the expansion option must be exercised as to the entire SSB Expansion Space), by notice to Landlord given not later than the earlier of (a) February 28, 2014 and (b) sixty (60) days following the date of Landlord’s notice, but in no event shall Tenant be obligated to exercise an option earlier than September 30, 2013. If Tenant timely provides such notice, the SSB Expansion Spaces which Tenant elected to add to the Premises shall be added thereto as of January 1, 2015 (subject to any holdover by the tenant thereof).

Exhibit A-1 also designates a portion of the first floor of Tower I as space that may become Available (as hereinafter defined) prior to July 1, 2014. It is also possible that an SSB Expansion Space may become Available prior to July 1, 2014 by reason of a negotiated termination of the existing lease with respect to such SSB Expansion Space. Furthermore, space contiguous (vertically or horizontally) to the Initial Premises excluding the currently vacant (approximately 8,963 rsf) suite on the second floor of Tower Ill may become available by reason of a termination of lease. Each SSB Expansion Space that becomes Available prior to July 1, 2014; the Tower I Space described in Exhibit A-1 and any such contiguous space in Tower Ill that becomes Available prior to July 1, 2014, is referred to herein as an “Early Expansion Space” (and collectively as “Early Expansion Spaces”). If the current tenant of an Early Expansion Space notifies Landlord that it is willing to terminate its existing lease of an Early Expansion Space prior to July 1, 2014 and Landlord is willing, in its sole discretion, to permit such termination, Landlord shall notify Tenant of the anticipated date of such Early Expansion Space shall be Available (“EES Notice”), and Tenant shall have the option to expand the Initial Premises by the addition thereto of such Early Expansion Space, by notice (“EES Acceptance”) to Landlord given not later than the later to occur of (i) September 1, 2013 and (ii) thirty (30) days following the date Tenant receives the associated EES Notice.

An Early Expansion Space shall be added to the Premises on later to occur of September 1, 2013 and the Add Date (as hereinafter defined) for such Early Expansion Space.

“Add Date” as to an Early Expansion Space shall be five (5) business days following the later to occur of (A) the date the Landlord anticipated the Early Expansion Space would be available in the EES Notice and (B) the date such Early Expansion Space is Available and Tenant is given notice thereof by Landlord; but in no event prior to thirty (30) days following the date Tenant gives the EES Acceptance with respect to such Early Expansion Space; provided, however, the Add Date shall be deferred as provided in Article 7 with respect to Early Expansion Space to be delivered in “shell” rather than “as-is” condition as provided in Article 7.

Space shall be “Available” if the lease with respect thereto is terminated, such space is vacant and currently existing tenants of the Building do not have rights to such space which were

in effect as of the date of this Lease. It is understood that Tenant’s rights hereunder with respect to Tower IV are superior to rights of any third party including State Street Bank except with respect to the existing renewal option of State Street Bank (without modification).

With respect to SSB Expansion Space and Early Expansion Space added to the Premises hereunder, such space shall as of the date the same become a part of the Premises be leased on all of the terms and conditions of this Lease as if the same were a part of the Premises originally designated in Section 1.19, and, accordingly, (ii) Base Rent shall be increased by the Annual Base Rent per Rentable Square Foot set forth in Section 1.11 of this Lease multiplied by the rentable square feet in the SSB Expansion Space and/or Early Expansion Space so added to the Premises originally designated as of the date so added, (iii) the Tenant’s Proportionate Expense Share and Tenant’s Proportionate Tax Share will be increased to reflect the additional square footage in the Premises as of the date so added, and (iv) the Allowance under Section 38 shall be increased by an amount equal to $60.00 per rentable square foot contained in the added SSB Expansion Space and/or Early Expansion Space.

42.02 Expansion Rights. Tenant shall have two (2) additional options to expand the Premises, subject to Section 43.01(ii). The first option (“Expansion Option One”) is to expand the Premises by the addition thereto of approximately 16,654 rentable square feet on the 4th floor of Tower III (“Expansion Space One”) and the second option (“Expansion Option Two”) is to expand the Premises by the addition thereto of approximately 5,413 rentable square feet on the 4th floor of Tower III (“Expansion Space Two”). Expansion Space One and Expansion Space Two are designated on Exhibit A-3. In the event Tenant exercises a right of first offer as provided in Article 43 with respect to space within Expansion Space One and/or Expansion space Two, the space that landlord is obligated to deliver hereunder shall be correspondingly reduced. The right to exercise Expansion Option One is subject only to the prior rights of the current tenant thereof to extend or renew its lease thereof pursuant to existing rights contained in its lease as of the date hereof on or before March 31, 2014. The right to exercise Expansion Option Two is subject only to the right of first offer granted to the current tenant of Expansion Space One prior to the date of this Lease. Each option to expand requires notice of the exercise of the option by the applicable Expansion Notice Date (hereinafter defined), time being of the essence, and the space which is the subject of such option to expand shall be delivered by Landlord to Tenant by the applicable Expansion Delivery Date (as hereinafter defined). “Expansion Notice Date” for Expansion Option One is March 1, 2014 and for Expansion Option Two is July 1, 2014. “Expansion Delivery Date” for Expansion Space One is March 1, 2015 and for Expansion Space Two is July 1, 2015. Rent will be payable on the space added by the exercise of Expansion Option One beginning on July 1, 2015. Rent will be payable on the space added by the exercise of Expansion Option Two beginning on November 1, 2015. With respect to expansion space added to the Premises under this Section 42.02, such expansion space shall be leased on all of the terms and conditions of this Lease as amended from time to time, except that (i) the Term for such expansion space shall begin on the applicable Expansion Delivery Date and end on the Termination Date (as the same may be extended or reduced as provided in this Lease), (ii) Base Rent shall be increased by the addition thereto of the Annual Base Rent per Rentable Square Foot set forth in Section 1.11 of this Lease multiplied by the rentable square feet in the applicable expansion space, (iii) the Proportionate Share of Expenses and the Proportionate Share of Taxes will be increased to reflect the additional square footage in the Premises and (iv) Tenant shall receive an improvement allowance with respect to the

expansion space at a rate of $60.00 (not $68.04) per rentable square foot of the applicable expansion space multiplied by the ratio of the number of months in the term of the expansion space to the number of months in the original term of this Lease, such improvement allowance to be administered on the same terms as the Allowance under ARTICLE 38, but only disbursed to the extent of Qualified Costs related to the expansion space, without the right to apply any unused portion to free rent and such allowance must be requisitioned by December 31, 2016. The expansion space shall be otherwise delivered in “as-is” condition, broom clean and free of all personal property, debris, tenants and occupants. If Landlord is delayed delivering possession of Expansion Space One or Expansion Space Two, as applicable, beyond the applicable Expansion Delivery Date due to the holdover or unlawful possession of Expansion Space One or Expansion Space Two, as applicable, by any party, or otherwise, Landlord shall use reasonable efforts to obtain possession of, and deliver to Tenant, Expansion Space One or Expansion Space Two, as applicable, and the commencement of the term for Expansion Space One or Expansion Space Two, as applicable, and Tenant’s obligation to pay Rent therefor shall be postponed accordingly. If Landlord is unable to deliver an Expansion Space under this Section 42.02 by the date which is ninety (90) days following the applicable Expansion Delivery Date, Tenant shall have the right to withdraw its notice to expand the Premises by the addition of such Expansion Space at any time thereafter, but prior to delivery of such Expansion Space in the condition required hereunder, by thirty (30) days’ notice to Landlord of such withdrawal; provided, however, such notice of withdrawal shall be of no force or effect if, prior to the end of such thirty (30) days, Landlord delivers the Expansion Space to Tenant in the condition required hereunder.

42.03 Expansion Amendment. If Tenant exercises an expansion option under Section 41.01 and/or Section 42.02, Landlord shall prepare an amendment (an “Expansion Amendment”) adding the applicable expansion space to the Premises on the terms set forth above and reflecting the changes in the Base Rent, Rentable Square Footage of the Premises, Tenant’s Proportionate Share of Taxes and Tenant’s Proportionate Share of Expenses and other appropriate terms. A copy of the Expansion Amendment shall be sent to Tenant and, subject to Landlord and Tenant agreeing upon any reasonable changes requested by Tenant, Tenant shall execute and return the expansion Amendment to Landlord within thirty (30) days thereafter, and Landlord shall deliver a copy thereof executed by Landlord to Tenant, but an otherwise valid exercise of an expansion option shall be fully effective, whether or not an Expansion Amendment is executed.

42.04 Bentley Space. In the event Tenant is offered and elects to sublease the “Bentley” space consisting of 13,294 rentable square feet of space on the 7th floor of Tower Ill, designated by Landlord as Space #3701, from the tenant thereof, Landlord will consent to such sublease to Tenant and provide Tenant the option to add the sublease space to the Premises upon expiration of such sublease on the terms then in effect under this Lease, and if Tenant adds the sublease space to the Premises, Tenant shall receive an improvement allowance with respect to the expansion space at a rate of $60.00 (not $68.04) per rentable square foot of such space multiplied by the ratio of the number of months remaining in the term of this Lease at the date such space becomes a part of the Premises to the number of months in the original term of this Lease, such improvement allowance to be administered on the same terms as the Allowance under ARTICLE 38, but only disbursed to the extent of Qualified Costs related to the Bentley space, without the right to apply any unused portion to free rent.

ARTICLE 43.
RIGHT OF FIRST OFFER

43.01 Grant of Option; Conditions. Tenant shall have a continuing right of first offer (the “Right of First Offer”) with respect to the following space in the Office Section:

(i) Commencing on the date hereof, all space in Tower IV other than on the first floor;

(ii) Commencing on the date hereof, any space in Tower Ill that is contiguous to the then Premises, whether on a floor above or below the Premises (including SSB Expansion Space and Early Expansion Space not added under Section 41.01 and any expansion space under Section 41.02) or on the same floor as a portion of the Premises, but in Tower Ill;

(iii) Commencing July 1, 2019, any space in Tower I, but subject to the rights, existing as of the date of this Lease, of other tenants of the Building.

Any such space that becomes available as hereinafter described is referred to herein as the “Offering Space”. If during the Term Landlord determines (in Landlord’s sole judgment) that Offering Space is available to lease to a third party other than the existing tenant or licensee of the Offering Space, then Landlord shall so advise Tenant (the “Advice”). Tenant may lease such Offering Space in its entirety only, under the applicable terms described below, by delivering written notice of exercise to Landlord (the “Notice of Exercise”) within ten business (10) days after the date of the Advice. In any event, Tenant’s delivery of a Notice of Exercise shall be deemed to be the irrevocable exercise by Tenant of its Right of First Offer subject to and in accordance with the provisions of this ARTICLE 43. Any reference to the Advice below shall be a reference to the Advice with respect to which a Notice of Exercise was given.

Notwithstanding the foregoing, Tenant shall have no such Right of First Offer and Landlord need not provide Tenant with an Advice, if:

(a) A material default is then continuing at the time that Landlord would otherwise deliver the Advice; or

(b) Tenant herein named (or a transferee pursuant to a Related Party Transfer, as defined in ARTICLE 17 of this Lease) is not in occupancy of at least 70% of the Premises initially leased at the time Landlord would otherwise deliver the Advice; or

(c) This Lease has been assigned (other than pursuant to a Related Party Transfer) prior to the date Landlord would otherwise deliver the Advice.

43.02 Terms for Offering Space. The term for the Offering Space shall commence upon the commencement date stated in the Advice and shall thereafter continue for the balance of the Term of this Lease as the same may be extended; provided, however, in the event the commencement date for Offering Space as set forth in the Advice is to commence on or after July 1, 2019, the term of the lease with respect to the Offering Space shall be the term set forth in the Advice with respect thereto. The Offering Space shall be added to the then Premises under

this Lease on all of the terms and conditions of this Lease as the same may be amended from time to time except as hereinafter provided and except as provided in the immediately preceding sentence. In the event the Offering Space becomes a part of the Premises prior to July 1, 2019, as of the date the Offering Space term commences (i) the amount added to Base Rent on account of the Offering Space shall be the Annual Base Rent per Rentable Square Foot set forth in Section 1.11 of this Lease multiplied by the rentable square feet in the Offering Space and (ii) the Tenant’s Proportionate Expanse Share and Tenant’s Proportionate Tax Share shall be increased to reflect the additional square footage in the Premises and (iii) Tenant shall receive an improvement allowance to be used for Qualified Costs with respect to the Offering Space at a rate of $60.00 per rentable square foot in the Offering Space multiplied by the ratio of the number of months in the Offering Space term to the number of months in the original Term of this Lease, such improvement allowance to be administered on the same terms as the Allowance under ARTICLE 38, but only disbursed to the extent of Qualified Costs related to the Offering Space, without the right to apply any unused portion to rent and such improvement allowance must be requisitioned by the date which is fifteen (15) months following the date of delivery of the Offering Space, but the Offering Space shall be otherwise delivered in the condition set forth in the Advice. In the event the Offering Space becomes a part of the Premises after June 30, 2019, Base Rent under this Lease shall be increased by the Prevailing Market Rent (as hereinafter defined) for the Offering Space and the terms and conditions under which the Offering Space shall be leased (including, without limitation, the duration of the term for the Offering Space) shall otherwise be as set forth in the Advice with respect to the Offering Space.

43.03 Definition of Prevailing Market Rent. “Prevailing Market Rent” for purposes of this ARTICLE 43 shall mean the rent (base rent and additional rent adjusted, if necessary, to reflect the base years to be used for the applicable period) per rentable square foot for similar office space in the Building and in comparable buildings as reasonably located in the City of Boston (i) taking into account (A) any difference in the base years between the Offering Space and the compared space for measurement of additional rent on account of taxes and expenses, (B) the magnitude of any free rent or buildout allowance included in rent for the compared space, (C) length of lease, (D) building amenities in the respective buildings, (E) the location and floor levels of the Offering Space and the compared space, (F) services provided in the respective buildings, (G) surrender rights, if any, in the compared space (H) parking rights and obligations, (I) free rent, tenant allowances or other concessions in the compared space and (J) all other relevant market factors and (iii) taking into account the brokerage commissions, if any, to be paid in connection with the leasing the respective spaces.

43.04 Determination of Prevailing Market Rent. Within thirty (30) days after Landlord’s receipt of the Notice of Exercise, if Base Rent is to be determined with reference to Prevailing Market Rent, Landlord shall provide Tenant with its good faith estimate of the Prevailing Market Rent. If, within thirty (30) days after Tenant’s receipt of Landlord’s estimate, Tenant shall not have notified Landlord of its objection to Landlord’s estimate and of Tenant’s estimate of Prevailing Market Rent, the estimate of Prevailing Market Rent quoted by Landlord shall be deemed to be the Prevailing Market Rent for the Offering Space. If Tenant so notifies Landlord of its objection, the parties shall discuss the matter in good faith for thirty (30) days after Tenant’s objection notice. If within such thirty (30) day period the parties have not agreed on the Prevailing Market Rent rate in writing, then Landlord and Tenant shall, during the ensuing fifteen (15) days, attempt to agree on an arbitrator not affiliated with either party (and if they are

unable to do so, either party may request that the President of the American Arbitration Association in Boston choose an arbitrator, as promptly as possible, meeting the criteria set forth below; provided, however, the parties shall have the right during the ten (10) day period following the end of the fifteen (15) day period to submit the names of not more than two (2) potential arbitrators meeting the said criteria and if the parties or either of them makes such a submission, the choice of the President of the American Arbitration Association shall be made from the arbitrators so submitted). Such arbitrator shall have a period of thirty (30) days to determine which of Landlord’s estimate of Prevailing Market Rent or Tenant’s estimate of Prevailing Market Rent hereunder more closely corresponds to the Prevailing Market Rent and the estimate of Prevailing Market Rent which more closely corresponds to the arbitrator’s estimate of Prevailing Market Rent shall be the Prevailing Market Rent for purposes hereof with respect to the subject Offering Space and the determination shall be binding upon the parties. The arbitrator must choose either the Prevailing Market Rent estimate submitted by Landlord or the Prevailing Market Rent Estimate submitted by Tenant. Such arbitrator shall have at least ten (10) years’ experience in the valuation and appraisal of first-class office rents for real estate in the City of Boston, be experienced with leasing transactions exceeding 100,000 square feet within the downtown Boston area, and have no then contractual relationship with either Landlord or Tenant. The expenses of the arbitrator shall be borne equally by the Landlord and the Tenant.

43.05 Condition of Offering Space. The Offering Space (including improvements therein) shall be delivered to Tenant broom-clean and free of occupants and personal property but otherwise in its condition and as-built configuration existing on the earlier of the date Tenant takes possession of the Offering Space or as of the date the term for such Offering Space commences. If Landlord is delayed delivering possession of the Offering Space due to the holdover or unlawful possession of the Offering Space by any party, or otherwise, Landlord shall use reasonable efforts to obtain possession of the Offering Space, and the commencement of the term for the Offering Space and Tenant’s obligation to pay Rent for such Offering Space shall be postponed until the date Landlord delivers possession of the Offering Space to Tenant free from occupancy by any party and otherwise in the condition required hereunder. If Landlord is unable to deliver an Offering Space under this Article 43 by the date which is ninety (90) days following the commencement date set forth in the applicable Advice, Tenant shall have the right to withdraw its notice to add the Offering Space to the Premises at any time thereafter, but only prior to delivery of such Expansion Space in the condition required hereunder, by thirty (30) days’ notice to Landlord of such withdrawal; provided, however, such notice of withdrawal shall be of no force or effect if, prior to the end of such thirty (30) days, Landlord delivers the Offering Space to Tenant in the condition required hereunder.

43.06 Offering Amendment. If Tenant exercises its Right of First Offer, Landlord shall prepare an amendment (an “Offering Amendment”) adding the Offering Space to the Premises on the terms set forth in the Advice and reflecting the changes in the Base Rent, Rentable Square Footage of the Premises, Tenant’s Proportionate Share of Taxes and Tenant’s Proportionate Share of Expenses and other appropriate terms. A copy of the Offering Amendment shall be sent to Tenant and, subject to Landlord and Tenant agreeing upon any reasonable changes requested by Tenant, Tenant shall execute and return the Offering Amendment to Landlord within thirty (30) days thereafter, but an otherwise valid exercise of a Right of First Offer shall be fully effective, whether or not an Offering Amendment is executed.

ARTICLE 44.
ROOFTOP COMMUNICATIONS

Landlord hereby grants to Tenant a license to use space on the roof of the Building for communications infrastructure, Tenant shall have the right to access and use the roof of the Building (such right being referred to herein as a “Roof License”), commencing on the Commencement Date, in accordance with the following terms and conditions:

A. During the term of a Roof License, Tenant, at no additional cost other than the costs incurred by Tenant in connection with installation and maintenance, may use the Roof Space (as hereinafter defined) for the purpose of installing, operating and maintaining microwave dishes, antennae and/or other communication devices approved by the Landlord (each, a “Dish/Antenna”), such approval not to be unreasonably withheld, conditioned or delayed. Tenant shall have no right to use the Roof Space under a Roof License subsequent to the Termination Date. Tenant may elect to terminate the use of the Roof Space and so terminate the Roof License under which Tenant is using the Roof Space by giving not less than thirty (30) days notice to Landlord of Tenant’s intention to cease using the Roof Space, complying with its obligations relating to removal of the Dish/Antenna Items (as defined below) not later than such date. The exact location of the space on the roof to be used by Tenant under a Roof License shall be reasonably designated by Landlord (the “Roof Space”). Landlord reserves the right at Landlord’s sole cost and expense and without material disruption to Tenant, to relocate the Roof Space as reasonably necessary during the Term. Landlord’s designation shall take into account Tenant’s use of the Dish/Antenna Items. Notwithstanding the foregoing, Tenant’s right to install the Dish/Antenna shall be subject to the reasonable approval rights of Landlord and Landlord’s architect and/or engineer with respect to the plans and specifications of the Dish/Antenna Items (as hereinafter defined) including without limitation appearance, the size of the Dish/Antenna, the manner in which the Dish/Antenna is attached to the roof of the Building and the manner in which any cables are run to and from the Dish/Antenna, it being understood that Tenant shall have the right at its cost and expense to run conduit to connect the Premises to the Dish/Antenna, provided that Tenant installs such conduit in existing chases reasonably designated by Landlord, installs such conduit in a manner that avoids, and at times that do not result in, interference with other tenants of the Building as of the date of this Lease and their equipment and installations and performs such installation in compliance with rules with respect thereto from time to time promulgated by Landlord using contractors approved by Landlord and providing such insurance coverage as Landlord may reasonably require. The Dish/Antenna must be tagged with weatherproof labels showing manufacturer, model, frequency range, and name of Tenant. In addition, the cable between the Dish/Antenna and the Premises, and any other cable connected to the Dish/Antenna (the “Dish/Antenna Cable”) must be tagged in the telecom closet on each floor with a label showing Tenant’s name, phone number and suite number. The precise specifications and a general description of the Dish/Antenna along with all documents Landlord reasonably requires to review the installation of the Dish/Antenna Items (the “Communications Plans and Specifications”) shall be submitted to Landlord for Landlord’s written approval no later than twenty (20) days before Tenant commences to install the Dish/Antenna. Tenant shall be solely responsible for obtaining all necessary governmental and regulatory approvals and for the cost of installing, operating, maintaining and removing the Dish/Antenna. Tenant shall notify Landlord upon completion of the installation of the Dish/Antenna Items. If Landlord determines that the Dish/Antenna does not comply with the approved Communications Plans and

Specifications, that the Building has been damaged during installation of the Dish/Antenna Items or that the installation was defective, Landlord shall notify Tenant of any noncompliance or detected problems and Tenant shall act promptly with the application of diligence to cure the defects. If the Tenant fails to promptly cure the defects, Tenant shall pay to Landlord upon demand the cost, as reasonably determined by Landlord, of correcting any defects and repairing any damage to the Building caused by such installation. If at any time Landlord, in its sole but reasonable discretion, deems it necessary, Tenant shall provide and install, at Tenant’s sole cost and expense, appropriate aesthetic screening, reasonably satisfactory to Landlord, for the Dish/Antenna (the “Aesthetic Screening”).

B. Landlord agrees that during the term of a Roof License, Tenant, upon reasonable prior written notice to Landlord, shall have access to the Building and the Roof Space for the purpose of installing, maintaining, repairing and removing the Dish/Antenna, Dish/Antenna Cable, the appurtenances and the Aesthetic Screening, if any (collectively, the “Dish/Antenna Items”), all of which shall be performed by Tenant or Tenant’s authorized representative or contractors, which shall be approved by Landlord (such approval not to be unreasonably withheld, conditioned or delayed), at Tenant’s sole cost and risk. It is agreed, however, that only authorized engineers, employees or properly authorized contractors of Tenant, FCC inspectors, or persons under their direct supervision will be permitted to have access to the roof of the Building and the Roof Space. Tenant further agrees to exercise such control over the people requiring access to the roof of the Building and the Roof Space as is necessary to keep to a minimum the number of people having access to the roof of the Building and the Roof Space and the frequency of their visits.

C. It is further understood and agreed that the installation, maintenance, operation and removal of the Dish/Antenna Items are not permitted to damage the Building or the roof thereof, or unreasonably interfere with the use of the Building and roof by Landlord or other tenants of the Building. Tenant shall be responsible for any material damage caused to the roof or any other part of the Building, to the extent caused by Tenant or any of its agents or representatives as a result of Tenant’s exercise of its rights under a Roof License under this ARTICLE 44. Tenant agrees that at all times during the term of a Roof License, it will keep the roof of the Building and the Roof Space free of all trash or waste materials produced by Tenant or Tenant’s agents, employees or contractors.

D. Tenant agrees to install only Dish/Antenna Items of types and frequencies which will not cause unreasonable interference to Landlord or existing tenants of the Building. If Tenant’s Dish/Antenna Items cause such interference, Tenant will change the frequency on which it transmits and/or receives and take any other steps necessary to eliminate the interference including relocating the Dish/Antenna to another location on the roof of the Building made available by Landlord. If said interference cannot be eliminated within a reasonable period of time, in the reasonable judgment of Landlord, then Tenant agrees to remove the Dish/Antenna from the Roof Space and to remove such other Dish/Antenna Items as Landlord may request, but may reinstall the same, at Tenant’s sole cost and expense, when it has demonstrated that such reinstallation will not result in interference.

E. Tenant, at its sole cost and expense, and at its sole risk, shall install, operate and maintain the Dish/Antenna Items in a good and workmanlike manner, and in compliance with all

building, electric, communication, and safety codes, ordinances, standards, regulations and requirements, now in effect or hereafter promulgated, of the Federal Government, including, without limitation, the Federal Communications Commission (the “FCC”), the Federal Aviation Administration (“FAA”) or any successor agency of either the FCC or FAA having jurisdiction over radio or telecommunications, and of the state, city and county in which the Building is located. Landlord and its agents assume no responsibility for the licensing, operation and/or maintenance of the Dish/Antenna Items. Tenant has the responsibility of carrying out the terms of its FCC license in all respects. The Dish/Antenna shall be connected to Landlord’s power supply in strict compliance with all applicable building, electrical, fire and safety codes. Neither Landlord nor its agents shall be liable to Tenant for any stoppages or shortages of electrical power furnished to the Dish/Antenna or the Roof Space because of any act, omission or requirement of the public utility serving the Building, or the act or omission of any other tenant, invitee or licensee or their respective agents, employees or contractors, or for any other cause beyond the reasonable control of Landlord, and Tenant shall not be entitled to any rental abatement for any such stoppage or shortage of electrical power. Except as may arise from the negligence of the Landlord, neither Landlord nor its agents shall have any responsibility or liability for the conduct or safety of any of Tenant’s representatives or repair, maintenance and engineering personnel while in or on any part of the Building or the Roof Space in connection with installing or maintaining the Dish/Antenna Items. No failure of service under a Roof License shall constitute a Service Failure under this Lease.

F. The Dish/Antenna Items shall remain the personal property of Tenant, and shall be removed by Tenant at its own expense at the expiration or earlier termination of a Roof License or Tenant’s right to possession hereunder. Tenant shall repair any damage caused by such removal, including the patching of any holes. Tenant agrees to maintain all of the Dish/Antenna Items placed on or about the roof or in any other part of the Building in proper operating condition and maintain same in satisfactory condition as to safety in Landlord’s sole discretion. Such maintenance and operation shall be performed in a manner to avoid any unreasonable interference with any other tenants or Landlord.

G. In light of the specialized nature of the Dish/Antenna, Tenant shall be permitted to utilize the services of its choice for installation, operation, removal and repair of the Dish/Antenna Items, subject to the reasonable approval of Landlord. Notwithstanding the foregoing, Tenant must provide Landlord with prior written notice of any such installation, removal or repair and coordinate such work with Landlord in order to avoid voiding or otherwise adversely affecting any warranties granted to Landlord with respect to the roof. If necessary, Tenant, at its sole cost and expense, shall retain any contractor having a then existing warranty in effect on the roof to perform such work (to the extent that it involves the roof), or, at Tenant’s option, to perform such work in conjunction with Tenant’s contractor. If Landlord contemplates roof repairs that could affect Tenant’s Dish/Antenna, or which may result in an interruption of the Tenant’s telecommunication service, Landlord shall formally notify Tenant at least thirty (30) days in advance (except in cases of an emergency) prior to the commencement of such contemplated work in order to allow Tenant to make other arrangements for such service and Landlord shall diligently perform (or cause the performance of) such roof repairs so as to minimize the interference of Tenant’s Dish/Antenna.

H. Tenant shall not allow any provider of telecommunication, video, data or related services (“Communication Services”) to locate any equipment on the roof of the Building or in the Roof Space for any purpose whatsoever unrelated to Tenant’s (or its permitted subtenants’) own use, nor may Tenant use the Roof Space and/or Dish/Antenna to provide Communication Services to an unaffiliated tenant, occupant or licensee of another building, or to facilitate the provision of Communication Services on behalf of another Communication Services provider to an unaffiliated tenant, occupant or licensee of the Building or any other building.

I. Tenant acknowledges that Landlord may at some time establish a standard license agreement (“Standard License Agreement”) with respect to the use of roof space by tenants of the Building. Tenant, upon request of Landlord, shall enter into such Standard License Agreement with Landlord provided that such agreement does not materially alter the rights or obligations of Tenant for a Roof License hereunder with respect to the Roof Space.

J. Tenant specifically acknowledges and agrees that the terms and conditions of ARTICLE 14 regarding indemnification and waiver of claims shall apply with full force and effect to Roof Space and any other portions of the roof accessed or utilized by Tenant, its representatives, agents, employees or contractors.

K. If Tenant defaults under any of the terms and conditions of this ARTICLE 44, and Tenant fails to cure said default within any applicable cure period provided for in this Lease, the same shall be an Event of Default under ARTICLE 24 of this Lease, but Landlord’s sole remedies for such a default shall be to terminate a then-existing Roof License on notice to Tenant and, in addition, Landlord may perform any non-monetary obligations of Tenant hereunder, including, without limitation the obligations of Tenant to remove all or any of the Dish/Antenna Items, and restore the Building and the Roof Space to the condition that existed prior to the installation of the Dish/Antenna Items. Tenant shall be liable for all out of pocket costs and expenses Landlord incurs in removing such Dish/Antenna Items and repairing any damage to the Building, the roof of the Building and the Roof Space caused by the installation, operation or maintenance of the Dish/Antenna Items. In such event, Tenant shall reimburse Landlord for all such costs incurred by Landlord as aforesaid together with an administrative charge equal to 10% of the cost of the work performed by Landlord. The amount to be reimbursed hereunder shall be paid together with interest from the date such cost is paid by Landlord (as evidenced by paid invoices supplied by Landlord to Tenant) at the rate of 12% per annum.

ARTICLE 45.
EMERGENCY GENERATOR

A. In addition to Tenant’s rights under ARTICLE 44 of this Lease, Landlord hereby grants to Tenant the right to install in a location or locations (collectively “Location”) in the lower level of the Building mutually agreeable to Landlord and Tenant, a standby generator and related equipment. The generator and such equipment installed by Tenant, together with the equipment already referred to in said ARTICLE 44, shall be included in the definition of Equipment for all purposes of this Lease. · Notwithstanding anything elsewhere in this Lease to the contrary, the generator and related equipment need not be removed by Tenant prior to the Termination Date but shall be removed by Tenant no later than the Termination Date. Obligations with respect to removal shall survive any termination of this Lease.

B. Landlord agrees that Tenant, upon reasonable prior written notice to Landlord, shall have access to the Location for the purpose of installing, maintaining, repairing and removing the generator and related equipment, all of which shall be performed by Tenant or Tenant’s authorized representative or contractors, which shall be approved by Landlord (such approval to be not unreasonably withheld, conditioned or delayed), at Tenant’s sole cost and risk. It is agreed, however, that only authorized engineers, employees or properly authorized contractors of Tenant or persons under their direct supervision will be permitted to have access to the Location. Tenant further agrees to exercise firm control over the people requiring access to the Location in order to keep to a minimum the number of people having access to the Location and the frequency of their visits.

C. Tenant agrees to be responsible for any damage caused to the Location or any other part of the Building, which may be caused by Tenant or any of its agents or representatives as a result of Tenant’s exercise of its rights under this ARTICLE 45.

D. Tenant, at its sole cost and expense, and at its sole risk, shall install, operate and maintain the generator and related equipment in a good and workmanlike manner, and in compliance with all building and safety codes, ordinances, standards, regulations and requirements, now in effect or hereafter promulgated. Landlord and its agents assume no responsibility for the licensing, operation and/or maintenance of the generator and related equipment. Except as may arise from the negligence of the Landlord, neither Landlord nor its agents shall have any responsibility or liability for the conduct or safety of any of Tenant’s representatives or repair, maintenance and engineering personnel while in or on any part of the Building or the Location in connection with installing or maintaining the generator and related equipment. No failure of service hereunder shall constitute a Service Failure under this Lease.

E. Tenant agrees to maintain all of the generator and related equipment placed on or about the Location or in any other part of the Building in proper operating condition and maintain same in satisfactory condition as to safety in Landlord’s sole, reasonable discretion. Such maintenance and operation shall be performed in a manner to avoid any unreasonable interference with any other tenants or Landlord.

F. In light of the specialized nature of the generator and related equipment, Tenant shall be permitted to utilize the services of its choice for installation, operation, removal and repair of the generator and related equipment, subject to the reasonable approval of Landlord. Notwithstanding the foregoing, Tenant must provide Landlord with prior written notice of any such installation, removal or repair and coordinate such work with Landlord in order to avoid voiding or otherwise adversely affecting any warranties granted to Landlord with respect to the Location.

G. Tenant specifically acknowledges and agrees that the terms and conditions of ARTICLE 14 regarding indemnification and waiver of claims shall apply with full force and effect to the Location and any other portions of the Building accessed or utilized by Tenant, its representatives, agents, employees or contractors.

H. If Tenant defaults under any of the terms and conditions of this ARTICLE 45, and Tenant fails to cure said default within any applicable cure period provided for in this Lease, the

same shall be an Event of Default under ARTICLE 24 of this Lease, but Landlord’s sole remedies for such a default shall be to terminate the rights hereunder on notice to Tenant and Tenant and, in addition, Landlord may perform any non-monetary obligations of Tenant hereunder, including, without limitation the obligations of Tenant to remove all or any of the generator and related equipment, and restore the Location to the condition that existed prior to the installation of the generator and related equipment. Tenant shall be liable for all out of pocket costs and expenses Landlord incurs in removing the generator and related equipment and repairing any damage to the Building caused by the installation, operation or maintenance of the generator and/or related equipment. In such event, Tenant shall reimburse Landlord for all such costs incurred by Landlord as aforesaid together with an administrative charge equal to 10% of the cost of the work performed by Landlord. The amount to be reimbursed hereunder shall be paid together with interest from the date such cost paid is by Landlord (as evidenced by paid invoices supplied by Landlord to Tenant) at the rate of 12% per annum.

MEASUREMENT STANDARDS

I. Measurement Standards- Single Tenancy Floors. Three steps, in sequence, are to be followed to determine the Total Rentable Area: (i) compute gross area, (ii) deduct certain areas, and (iii) add applicable share of areas to be apportioned (see paragraph C below).

X. Xxxxx Area: The gross area of a floor shall be the entire area within the exterior walls. If the exterior wall consists in whole or part of windows, fixed clear glass or other transparent material, the measurement along the entire such wall shall be taken to a line established by the vertical plan of the inside of the glass or other transparent material. If it consists solely of a nontransparent material, the measurement shall be taken to the inside surface of the outer building wall. If a floor has no exterior wall within the property line, measurements shall be taken to the property line. If a floor has no full-height enclosure wall, measurement shall be taken to the edge of the floor slab.

B. Deductions from Gross Area: The following non-rentable building areas with one-half of their enclosing walls are to be deducted.

1. Public elevator shafts and associated elevator machine rooms.

2. Required egress stairways.

3. Areas within the gross area which are to be apportioned pursuant to paragraph (C) below.

C. Areas to be apportioned (“Attributable Area”):

1. Common facilities including, without limitation, all heating, ventilating, air conditioning, mechanical, electrical, cooling tower, telephone and other service floors, rooms or areas, containing equipment or supplies (exclusive of any tenant special air conditioning or mechanical area or facilities) and all public lobbies (including monumental stair and/or escalator), loading and other common service areas, throughout and within the Building including one-half of their enclosing walls, are to be apportioned.

Exhibit E-1

2. Whenever the height of any room or space used for a heating, ventilating, air conditioning, mechanical, or electrical facility above the ground floor shall exceed the average story height in the Building by more than 25 percent, then the floor area of such room or space shall be determined by multiplying the actual floor area by the percentage that the height of the room or space exceeds the average story height, and adding the area so determined to the actual floor area of such room or space; however, if any such rooms or spaces penetrate the next higher floor, then the entire area of such room or space on both floors shall be apportioned under this paragraph (C).

II. Measurement Standards - Multiple Occupancy Floors. The sum of the Total Rentable Area for two or more tenants on a floor shall be the Total Rentable Area for that floor as computed in the manner for single tenancy floors. Three steps are to be followed to determine the Total Rentable Area for each tenant on a multiple occupancy floor: (i) compute the Net Rentable Area for such floor pursuant to (a) below, (ii) compute the Net Rentable Area for each tenant pursuant to (b) below, and (iii) multiply the Total Rentable Area of such floor by a fraction whose numerator is the Net Rentable Area for such tenant and whose denominator is the Net Rentable Area for such floor.

A. Net Rentable Area for Any Floor: The Net Rentable Area shall be the gross area as described for single tenancy floors less the entire core area (measured to the finished enclosing walls thereof, but excluding any part of the core rented to a tenant) and corridors (measured to the corridor side of the finished enclosing walls of the corridor).

B. Net Rentable Area for Each Tenant: Exterior walls are to be measured as described in the procedure for gross area. Demising walls between tenants are to be equally divided. Corridor walls to the finished corridor side are to be included in the Net Rentable Area of each tenant.

III. Rentable Calculation. Rentable Area is determined by measuring gross area less deductions (assuming all full floor occupants) and multiplying by 1.165.
