In addition to the Premises, Tenant shall have the nonexclusive right, in common with Landlord and all others to whom Landlord has granted or may hereafter grant rights, to use (a) the common lobbies, corridors, stairways, elevators and loading platforms of the Building, and if the Premises include less than an entire floor, the common toilets, corridors and elevator lobby for such floor, and (b) the common walkways and driveways of the Park for access, ingress, egress, parking and vehicular circulation to the Building, and any common area facilities of the Park from time to time made available by Landlord for the use of tenants of the Park. Tenant’s use of all such common areas shall be subject to such reasonable restrictions and regulations as Landlord may from time to time impose and the rights of Landlord set forth herein.

2.2 Lease Term.

2.2.1 Initial Lease Term. The Lease Term shall be for the period stated in the definition of that term, unless earlier terminated as provided in this Lease.

2.2.2 Option to Extend. While this Lease is in full force and effect, provided that no Event of Default then exists and no Event of Default has occurred within the immediately preceding twelve (12) month period, and further provided that the Original Tenant has not assigned this Lease nor sublet more than twenty-five percent (25%) of the Premises then demised to Tenant under this Lease (excluding transfers to Permitted Transferees), in each case both as of the time of option exercise and as of the commencement of the herein additional term, Tenant shall have the right or option (the “Extension Option”) to extend the original term of this Lease for one (1) period of five (5) years (the “Option Period”). The Extension Option shall not apply to any ROFR Space that is added to the Premises in connection with paragraph 6.20 of this Lease, as any extension of the term of Tenant’s leasing of the ROFR Space shall be governed by the Offer. Such extension of the original term shall be on the same terms and covenants as provided for in the original term except that (a) Tenant shall have no further option to extend the Lease Term, (b) the Base Rent for the Option Period shall be one hundred percent (100%) of the then Fair Market Rent for the Premises in AS IS condition for lease renewals as determined in accordance with subparagraph 2.2.3, and (c) Landlord shall have no obligation to prepare, refurbish or construct the Premises or any part thereof prior to the commencement of the Option Period, nor shall Landlord have any obligation to provide Tenant with any tenant improvement allowance or other allowance of any kind. Any exercise of such Extension Option by Tenant as provided herein shall be irrevocable. If the Fair Market Rent has not been determined as of the commencement date of the Option Period, Tenant initially shall pay Base Rent plus escalations for the extended term at the Fair Market Rate designated by Landlord, with a retroactive adjustment to be made within ten (10) Business Days after the determination of Fair Market Rent. Notice (the “Option Notice”) of Tenant’s intention to exercise the Extension Option must be given to Landlord, in writing, at least twelve (12) months prior to the then current expiration of the Lease Term (time being of the essence) or the Extension Option shall lapse and be of no further force or effect. If Tenant exercises the Extension Option, after the determination of the Fair Market Rent for the Premises as herein provided, the Landlord and Tenant shall execute an amendment to this Lease confirming same.

2.2.3 Determination of Fair Market Rent for Extension Option. If Tenant exercises the Extension Option as provided above, Landlord and Tenant shall have a period of twenty (20) days after Landlord’s receipt of the Option Notice to agree upon the Fair Market Rent for the Premises. If Landlord and Tenant fail to reach agreement on the Fair Market Rent for the Premises, then the Fair Market Rent for the Premises shall be determined by three (3) licensed commercial real estate brokers, one of whom shall be named by Landlord, one of whom shall be named by Tenant, and the third of whom shall be selected by the brokers chosen by Landlord and by Tenant. All such brokers shall be independent and none of the brokers nor their firms shall have been employed by Landlord (with respect to the Building), Tenant or their affiliates for the immediately preceding five (5) years. A broker shall not be disqualified if he/she or their firm have been employed by Landlord within the preceding five (5) years with respect to any property other than the Building. Furthermore, each such broker shall be a commercial real estate broker licensed in Massachusetts, specializing in office leasing in the so-called “Route 128 corridor”, with not less than ten (10) years experience in appraising comparable commercial properties in such market and recognized as reputable within the local real estate industry (each such broker being defined herein f or purposes of this paragraph as a “Qualified Broker”). The parties each agree to select their Qualified Broker within ten (10) days after the expiration of the aforesaid twenty (20) day period. The third Qualified Broker shall be selected by the first two Qualified Brokers within ten (10) days after the first two (2) Qualified Brokers have been selected. If a party fails to timely select a Qualified Broker, the determination of the Fair Market Rent for the Premises shall be made by the Qualified Broker selected by the other party. Within fifteen (15) days after the third Qualified Broker has been selected, all of the Qualified Brokers shall meet to attempt to agree upon the Fair Market Rent for the Premises. If the Qualified Brokers are unable to reach agreement, all Qualified Brokers shall, within fifteen (15) days after the expiration of the preceding fifteen (15) day period, arrange to simultaneously submit to Landlord and Tenant in writing the Fair Market Rent for the Premises he or she deems appropriate (each such Qualified

Broker’s determination of Fair Market Rent for purposes of this paragraph being referred to herein as an “Appraisal”). If none of the Appraisals varies from the mean of the other two (2) Appraisals by more than ten percent (10%), the mean of the determinations of all three (3) Appraisals shall be the Fair Market Rent for the Premises. If, on the other hand, any single Appraisal varies from the mean of the other two (2) Appraisals by more than ten percent (10%), the mean of the two (2) Appraisals which are closest shall be the Fair Market Rent for the Premises. The Fair Market Rent for the Premises determined in accordance with this subparagraph 2.2.3 shall be final and binding on Landlord and Tenant. Each of the parties to this Lease shall pay the costs of the services of the Qualified Broker selected by that party, and the cost of the services of the third Qualified Broker shall be divided equally between Landlord and Tenant.

2.3 Plans and Specifications.

2.3.1 Tenant has retained ▇▇▇▇▇▇▇ Architects, Inc. to prepare the Plans and Specifications for the Tenant Improvements. The plans and specifications shall be subject to Landlord’s approval, which approval shall not be unreasonably withheld or delayed, provided that such Plans and Specifications comply with the requirements of this paragraph 2.3. Tenant shall endeavor to design the Tenant Improvements consistent with the Landlord’s sustainability practices and certain Green Agency Ratings (as determined by Landlord), specifically the SMACNA “IAQ Guidelines for Occupied Buildings under Construction” 1995, Chapter 3. Tenant further agrees to engage a third party LEED or Green Globe Accredited Professional or similarly qualified professional with respect to the design and construction of the Tenant Improvements. Tenant also shall endeavor to construct the Premises to certified LEED CI standards, and Tenant shall have the right to request descriptions of recent commissioning and energy audits that the Landlord has undertaken to understand and retrofit building systems to the green/sustainable level referenced above.

2.3.2 Landlord hereby approves the space plan submitted by Tenant, a copy of which is attached hereto as Exhibit A (the “Space Plan”).

2.3.3 Tenant shall cause its architect to prepare from Tenant’s approved Space Plan, complete Plans and Specifications within a reasonable time after Landlord approves the Space Plan. The Plans and Specifications shall (a) be compatible with the Building shell and with the design, construction and equipment of the Building; (b) comply with all Governmental Requirements; (c) comply with all applicable insurance regulations; and (d) be consistent with the approved Space Plan. Tenant shall submit the Plans and Specifications for Landlord’s Approval in the same manner as provided in Subparagraph 2.3.2 above for approval by Landlord of Tenant’s Space Plan. If required by Landlord, Tenant’s architect shall consult with Landlord’s engineer in preparing the Plans and Specifications, and incorporate such engineer’s requirements into the Plans and Specifications. The fees of such engineer shall be a Tenant Improvement Cost (as hereafter defined). Landlord shall approve or disapprove the proposed Plans and Specifications within the five (5) Business Day period following its receipt of such Plans and Specifications. If Landlord shall disapprove of any portion of the Plans and Specifications, Landlord shall advise Tenant within such five (5) Business Day period of the reasons therefor and shall notify Tenant in writing of the revisions to the Plans and Specifications that are reasonably required by Landlord for the purpose of obtaining approval. Tenant shall within seven (7) days submit to Landlord, for Landlord’s approval, a redesign of the Plans and Specifications, incorporating the revisions required by Landlord. If a redesign of the Plans and Specifications is not approved by Landlord in its reasonable discretion within ten (10) Business Days following Landlord’s receipt of the first version of the Plans and Specifications submitted to Landlord for approval, then the period beginning on the tenth (10th) Business Day following Landlord’s receipt of the first version of the Plans and Specifications submitted to Landlord for approval until the date Landlord acting reasonably approves a subsequent redesign shall be deemed “Tenant Delay” and the Commencement Date shall be deemed to have occurred on the date that Substantial Completion would have been achieved absent such Tenant Delay. The failure of Landlord to approve or disapprove any proposed Plans and Specifications within the time period required hereunder shall constitute Landlord Delay and the Outside Commencement Date shall be extended for the period of such Landlord Delay.

2.3.4 Landlord shall grant an allowance to Tenant in an amount up to the Space Planning Allowance (as defined in Section 1 hereof) to be used solely to pay Tenant’s architect directly or to reimburse the Tenant for the fees (the “Space Planning Fees”) of Tenant’s architect in preparing the Space Plan. Payment by Landlord of the Space Planning Allowance (or such portion thereof as shall be eligible for disbursement hereunder) shall be made in a single disbursement and shall be subject to satisfaction of the following condition: Tenant shall have furnished Landlord with a copy of Tenant’s architect’s invoice for the Space Planning Fees and, in the case of Tenant’s written request for reimbursement to it of paid Space Planning Fees, evidence of payment of same,

2.4 Commencement Date. After the execution and delivery of this Lease by all parties hereto, Landlord shall deliver possession of the Premises to the Tenant for the purpose of making the Tenant Improvements in accordance with the terms hereof. The Commencement Date shall be the date set forth in the definition of that term in Section 1 hereof. Tenant acknowledges that the Premises shall be delivered AS IS and that no representations as to the condition of the Premises have been made by Landlord, provided that all base building systems shall be in good working order at the time of delivery of the Premises to Tenant. The taking of possession by Tenant shall establish that the Premises are in good and satisfactory condition when possession was so taken and the Commencement Date shall occur as provided in the definition of that term. In no event shall Tenant’s refusal or failure to take possession of the Premises delay or postpone the occurrence of the Commencement Date. Tenant’s possession of the Premises prior to the Commencement Date for purposes of moving in furniture and equipment, preparing cabling and wiring and performing the Tenant Improvements as provided above shall be subject to all of the terms and conditions of this Lease, except that Tenant shall not be required to pay Base Rent with respect to the period of time prior to the Commencement Date during which Tenant performs such work. Tenant, however, shall be liable for payment of any above standard services (such as after hours HVAC service) that are provided to Tenant during the period of Tenant’s possession prior to the Commencement Date).

2.5 Tenant’s Contribution to Tenant Improvement Costs.

2.5.1 Upon receipt of possession of the Premises, the Tenant shall prepare the Premises for Tenant’s occupancy and complete the Tenant Improvements in accordance with the Plans and Specifications in all material respects and at the Tenant’s sole cost and expense (all such costs and expenses, including all hard and soft costs such as and without limitation, all labor and materials, architectural, engineering, permitting, and space planning fees are hereinafter collectively referred to as the “Tenant Improvement Costs”). Tenant shall make no material changes to the Plans and Specifications or the work reflected in the Plans and Specifications without the consent of the Landlord, which consent shall not be unreasonably withheld provided such changes do not affect any structural elements of the Building or Building systems. In no event shall Tenant make any changes to the Plans and Specifications or the work reflected in the Plans and Specifications without the consent of the Landlord if such changes affect any structural elements of the Building or Building systems and/or the location of any door or wall. Tenant’s completion of the Tenant Improvements shall be performed by Tenant’s contractors, who shall (a) be selected by Tenant and approved by Landlord (such approval not to be unreasonably withheld or delayed), and (b) work under the direction of Tenant or, if directed in writing by Tenant, Tenant’s qualified representative. In the event of any dispute as to whether Substantial Completion as occurred, a certificate of occupancy shall be deemed conclusive. Landlord shall have the right, at Landlord’s sole cost and expense, to have its representative at the Premises at all times during the construction of the Tenant Improvements to review and monitor the performance of same, and Tenant shall pay Landlord a construction monitoring fee equal to one percent (1%) of the Tenant Improvement Costs (the “Construction Monitoring Fee”). The Tenant Improvements shall be performed by contractors approved by Landlord and employed by Tenant under one or more construction contracts that require the prime contractor and the respective subcontractors of any tier: (a) be parties to, and bound by, a collective bargaining agreement with a labor organization affiliated with the Building and Construction Trades Council of the AFL-CIO and (b) employ only members of such organization to perform work within their respective jurisdictions). However, at Landlord’s sole option, in clause (a) of the immediately preceding sentence of this paragraph, the following substitutions may be made: (1) a project labor agreement in place of a collective bargaining agreement, and (2) an independent, nationally recognized

labor organization in place of a labor organization affiliated with the Building and Construction Trades Council of the AFL-CIO. Such contractors also shall comply with all requirements in Paragraph 4.5 of this Lease. Landlord shall approve or disapprove any proposed contractor or construction contract within three (3) Business Days after Landlord’s receipt of a written request for such approval and containing the full name and address of the contractor and/or a complete copy of the construction contract (as applicable). Without limiting the foregoing, Tenant’s contract with its general contractor for the construction of the Tenant Improvements shall be subject to the approval of the Landlord as to both form and content, which approval shall not be unreasonably withheld or delayed.

2.5.2 All Tenant Improvements, regardless of which party constructed or paid for them, shall become the property of Landlord and shall remain upon and be surrendered with the Premises upon the expiration or earlier termination of this Lease; provided that, at Landlord’s election and upon notice to Tenant, Tenant shall be required to remove all or any portion of the Tenant Improvements (including Telecommunication Facilities) upon the expiration or earlier termination of this Lease. Notwithstanding the foregoing, except as provided below in this subparagraph 2.5.2, if Tenant’s submission of its Plans and Specifications to the Landlord for approval is accompanied by a written request that Landlord identify any Tenant Improvements that Landlord may require Tenant to remove upon the expiration or earlier termination of the Lease and such request includes a notice at the top of the page having a heading in at least 12-point type, bold and all capital letters stating “LANDLORD’S APPROVAL MUST IDENTIFY ANY TENANT IMPROVEMENTS WHICH LANDLORD MAY REQUIRE TENANT TO REMOVE UPON THE EXPIRATION OR EARLIER TERMINATION OF THIS LEASE”, then Landlord shall identify such Tenant Improvements (if any) by written notice to Tenant given at the time of Landlord’s approval of the Plans and Specifications, and Tenant shall not be required to remove any such Tenant Improvements not so identified. However, Tenant reserves the right to amend and resubmit the Plans and Specifications within seven (7) days after receipt of Landlord’s approval thereof, which seven (7) day period shall not constitute Tenant Delay the first time Tenant so amends and resubmits the Plans and Specifications. In all events, Landlord reserves the right to require Tenant to remove any wiring and cabling installed by Tenant. All unattached and moveable partitions, trade fixtures, moveable equipment or furniture located in the Premises and acquired by or for the account of Tenant which can be removed without damage to the Building or Premises, and all personalty brought into the Premises by Tenant (“Tenant’s Property”) shall be owned by Tenant and may be removed by Tenant subject to and in accordance with Paragraph 4.7 hereof, including but not limited to all servers, server racks, generators, supplemental HVAC units, furniture, phone and TV systems.

2.5.3 Tenant shall be solely responsible for the design and construction of the Tenant Improvements. Notwithstanding Landlord’s review and approval of the Plans and Specifications, Landlord shall have no liability to Tenant or to any other person for errors or omissions in the Plans and Specifications (Landlord’s review and approval of the Plans and Specifications being for Landlord’s own purposes). Tenant shall indemnify, defend, protect and hold Landlord and Landlord’s Agents harmless from all Claims which arise in any way, directly or indirectly from or in connection with the design and construction of the Tenant Improvements, including without limitation, claims arising from the work of Tenant’s architect, engineer, employees or agents, unless such design was mandated by Landlord over Tenant’s specific written objections thereto.

2.5.4 Landlord shall grant an allowance to Tenant in an amount up to the Tenant Improvement Allowance (as defined in Section 1.1 hereof) to be used solely to reimburse the Tenant for the Tenant Improvement Costs and to pay the Construction Monitoring Fee. Subject to the terms and conditions hereof, the Tenant Improvement Allowance shall be available for disbursement in monthly draws (each a “Tenant Allowance Advance”) plus one (1) final draw of the Retainage (as defined below) in the following manner. At least fifteen (15) Business Days before the date upon which the Tenant desires a Tenant Allowance Advance or an advance of the Retainage, the Tenant shall submit an itemized requisition (a “Requisition”) on a form acceptable to the Landlord in its reasonable discretion, stating the amount of the advance, the items(s) to be reimbursed from the proceeds thereof, and the date upon which the advance is desired. Each Tenant Allowance Advance shall be subject to retainage in the amount of ten percent (10%) (the “Retainage”). Landlord’s obligation to make any Tenant Allowance Advance shall be subject to Tenant’s satisfaction of all of the following conditions other than item number (6), and Landlord’s

obligation to advance the Retainage shall be subject to Tenant’s satisfaction of each and all of the following conditions numbered (1) through (6): (1) Tenant shall have submitted to Landlord a certification signed by Tenant’s architect certifying that all work on the Tenant Improvements which has been completed through the date of such certification (which shall be no earlier than the date of the subject Requisition) has been completed in all material respects in accordance with Plans and Specifications approved by the Landlord and attaching thereto an executed waiver or release of liens from Tenant’s general contractor for the Tenant Improvements for all work performed and materials delivered through the date of such Requisition, which waiver and release shall be in such form as Landlord may reasonably require, (2) Tenant shall have provided Landlord with executed waivers or releases of liens from each of Tenant’s subcontractors and suppliers for all work performed and materials delivered through the date of such Requisition, which waivers and releases shall be in such form as Landlord may reasonably require, (3) Tenant shall have submitted to Landlord a certification of Tenant’s general contractor for the Tenant Improvements identifying each contractor, subcontractor and supplier who performed labor and/or supplied materials for the Tenant Improvements through the date of such Requisition, (4) Tenant shall have furnished Landlord with copies of third party invoices, for all work performed and materials delivered which are included in such Requisition, (5) at the time of such Tenant Allowance Advance there shall exist no event which is, or solely with the passage of time and/or giving of notice would be, an Event of Default, and (6) with respect to the advance of the Retainage, Tenant shall have submitted to Landlord an issued and effective certificate of occupancy for the Premises for the Permitted Use and a certification signed by Tenant’s architect certifying that the Tenant Improvements have been completed in accordance with Plans and Specifications approved by the Landlord and attaching thereto executed final waivers or releases of liens from Tenant’s general contractor and each of Tenant’s subcontractors and suppliers in connection with the Tenant Improvements in such form as Landlord may reasonably require, plus a certificate of Tenant’s general contractor identifying each contractor, subcontractor and supplier who performed labor and/or supplied materials for the Tenant Improvements. The foregoing items (1) through (6) above are herein collectively referred to as the “Tenant Allowance Conditions”. Subject to satisfaction of all of the Tenant Allowance Conditions applicable to a particular Tenant Allowance Advance and/or advance of the Retainage, Landlord shall pay to Tenant, within fifteen (15) Business Days after receipt by Landlord of a written request from Tenant for a Tenant Allowance Advance or the Retainage (as applicable) in accordance with the foregoing (or on such later date as requested by Tenant), the lesser of (a) the full amount of the remaining undisbursed Tenant Improvement Allowance (after taking into account all Tenant Allowance Advances and deducting the aggregate amount of any undisbursed Retainage, except in the case of a final Requisition for the Retainage, and any unpaid balance of the Construction Monitoring Fee), if the aggregate sum of the invoices submitted pursuant to item (4) above equals or exceeds the full amount of the Tenant Improvement Allowance, or (b) the aggregate sum of invoices submitted pursuant to item (4) above (less the aggregate amount of any undisbursed Retainage, except in the case of a final Requisition for the Retainage, and any unpaid balance of the Construction Monitoring Fee), if said aggregate sum is less than the full amount of the Tenant Improvement Allowance. Except as and to the extent expressly provided in Paragraph 2.5.6 hereof, Tenant shall not be entitled to any credit, trade off or cash payment for any unused portion of the Tenant Improvement Allowance, and Landlord shall have no obligation to Tenant with respect to any such unused portion of the Tenant Improvement Allowance. Further, notwithstanding anything herein to the contrary, in the event that Tenant has not completed the Tenant Improvements and/or satisfied all of the conditions for payment of the Tenant Improvement Allowance on or before the date which is three hundred sixty (360) days after the Commencement Date (subject to a day for day extension for delays caused solely by Force Majeure, casualty and Landlord Delay), Landlord shall have no further obligation to make any Tenant Allowance Advance.

2.5.5 In all events, on or before the date which is three hundred sixty (360) days after the Commencement Date (subject to a day for day extension for delays caused solely by Force Majeure, casualty and Landlord Delay), (a) Tenant shall complete the Tenant Improvements, and (b) if not already done pursuant to Paragraph 2.5.4 above, Tenant shall submit to Landlord an issued and effective certificate of occupancy for the Premises for the Permitted Use and a certification signed by Tenant’s architect certifying that the Tenant Improvements have been completed in accordance with Plans and Specifications approved by the Landlord, together with executed final waivers or releases of liens from Tenant’s general contractor and each of Tenant’s subcontractors and suppliers in connection with the

Tenant Improvements in such form as Landlord may reasonably require, plus a certificate of Tenant’s general contractor identifying each contractor, subcontractor and supplier who performed labor and/or supplied materials for the Tenant Improvements.

2.5.6 Upon completion of the Tenant Improvements and application of the Tenant Improvement Allowance against the Tenant Improvement Costs and the Construction Monitoring Fee, the unexpended and unapplied balance of the Tenant Improvement Allowance (if any) up to the maximum aggregate amount provided for in Paragraph 2.5.7 hereof shall be available to Tenant in a single draw to reimburse Tenant for Tenant Expenditures upon receipt of a draw request (a “Tenant Expenditure Draw Request”) therefor in form and substance satisfactory to Landlord together with paid invoices, bills of sale, and any other documentation reasonably requested by Landlord. Except as provided in the immediately preceding sentence, Tenant shall not be entitled to receive any rent abatement, credit or payment on account of any unexpended portion of the Tenant Improvement Allowance.

2.5.7 In no event shall the aggregate amount of the Tenant Improvement Allowance applied against or used for Tenant Expenditures exceed an amount equal to One Hundred Ninety Thousand Two Hundred Fifty and 00/100 Dollars ($190,250.00) (based upon Five and 00/100 Dollars ($5.00) per rentable square foot of the Premises). Notwithstanding anything to the contrary contained herein, in the event that Tenant has not submitted a Tenant Expenditure Draw Request to Landlord with all required supporting documentation by the date which is three hundred sixty (360) days after the Commencement Date (time being of the essence), Landlord shall have no further obligation to fund or otherwise advance any of the Tenant Improvement Allowance for any Tenant Expenditures.

2.6 Lease Memorandum. Contemporaneously with Substantial Completion, Landlord shall prepare and submit to the Tenant a Lease Memorandum in the form of Exhibit D, completed in good faith by Landlord, and executed by Landlord. The information inserted on the Lease Memorandum shall be controlling and conclusive and shall prevail over any inconsistent provision in this Lease on (a) the mutual execution of the Lease Memorandum by Landlord and Tenant or (b) the lapse of seven (7) days following delivery of the Lease Memorandum to Tenant without Tenant delivering to Landlord a written objection to all or part of the information in the Lease Memorandum. If Tenant does object in good faith to any information set forth in the Lease Memorandum, it shall execute the Lease Memorandum subject to its specifically-stated, written objections. Tenant must explain the reasons for its objections in reasonable detail. That portion of the Lease Memorandum to which no objection was made shall be conclusive and controlling. Pending resolution of any dispute by agreement or a final determination by a court of competent jurisdiction in accordance with this Lease, Landlord’s information as inserted in the Lease Memorandum shall be utilized subject to any later adjustment agreed or found to be appropriate. Tenant’s refusal or failure to execute a Lease Memorandum shall neither prevent nor delay the occurrence of the Commencement Date. In no event shall the Lease Memorandum be recorded.

2.7 Use and Conduct of Business.

2.7.1 The Premises are to be used only for the Permitted Uses, and for no other business or purpose without the prior consent of Landlord. Landlord represents that the Premises are suitable for general office use but makes no representation as to Tenant’s particular use. Tenant shall, at its own cost and expense, obtain and maintain any and all licenses, permits, and approvals necessary or appropriate for its use, occupation and operation of the Premises for the Permitted Uses. Tenant’s inability to obtain or maintain any such license, permit or approval necessary or appropriate for its use, occupation or operation of the Premises shall not relieve it of its obligations under this Lease, including the obligation to pay Base Rent and Additional Rent.

2.7.2 No act shall be done in or about the Premises that is unlawful or that will increase the existing rate of insurance on any or all of the Land or Building. Tenant shall not commit or allow to be committed or exist: (a) any waste upon the Premises, (b) any public or private nuisance, or (c) any act or condition which disturbs the quiet enjoyment of any other tenant in the Building, violates any of Landlord’s contracts affecting any or all of the Land or Building, creates or contributes to any work stoppage, strike, picketing, labor disruption or dispute, interferes in any way with the business of Landlord or any other

tenant in the Building or with the rights or privileges of any contractors, subcontractors, licensees, agents, concessionaires, subtenants, servants, employees, customers, guests, invitees or visitors or any other persons lawfully in and upon the Land or Building, or causes any impairment or reduction of the good will or reputation of the Land or Building.

2.7.3 Tenant shall not, without the prior consent of Landlord, use any apparatus, machinery, device or equipment in or about the Premises which will cause any substantial noise or vibration or any increase in the normal consumption level of electric power, provided that anything included in the Plans and Specifications approved by Landlord shall be deemed to have been consented to by Landlord. If any of Tenant’s apparatus, machinery, devices or equipment should disturb the quiet enjoyment of any other tenant in the Building, then Tenant shall provide, at its sole cost and expense, adequate insulation or take other such action, including removing such apparatus, machinery, devices or equipment, as may be necessary to eliminate the disturbance; provided that Tenant shall not be required to remove any equipment to which Landlord has consented if such equipment is essential to the operation of Tenant’s business. Except as to those that will be used exclusively for the benefit of Tenant and Tenant’s employees and invitees, no food or beverage dispensing machines shall be installed by Tenant in the Premises without the prior written consent of Landlord.

2.7.4 Tenant shall use commercially reasonable efforts so as not to use or operate the Premises in any manner that will cause the Building or any part thereof not to conform with Landlord’s sustainability practices or the certification of the Building issued pursuant to any Green Agency Rating.

2.8 Compliance with Governmental Requirements and Rules and Regulations. Tenant shall comply with all Governmental Requirements and Restrictions relating to its use, occupancy and operation of the Premises and shall observe such reasonable rules and regulations as may be adopted and published by Landlord from time to time for the safety, care and cleanliness of the Premises and the Building, and for the preservation of good order in the Building and for the administration and management of the Building. Current Rules and Regulations are attached to this Lease as Exhibit E.

2.9 Intentionally Omitted.

2.10 Sustainable Building Operations.

2.10.1 This Building is or may become in the future certified under certain Green Agency Ratings or operated pursuant to Landlord’s sustainable building practices, as same may be in effect or modified from time to time. Landlord’s sustainability practices address, without limitation, whole-building operations and maintenance issues including chemical use; indoor air quality; energy efficiency; water efficiency; recycling programs; exterior maintenance programs; and systems upgrades to meet green building energy, water, Indoor Air Quality, and lighting performance standards. Tenant shall use commercially reasonable efforts to cause all of Tenant’s construction and maintenance methods and procedures, material purchases, and disposal of waste to be in compliance with minimum standards and specifications as outlined by the Green Agency Ratings, in addition to all Governmental Requirements.

2.10.2 Tenant shall use commercially reasonable efforts to use proven energy and carbon reduction measures, including energy efficient bulbs in task lighting; use of lighting controls; daylighting measures to avoid overlighting interior spaces; closing shades on the south side of the building to avoid over heating the space; turning off lights and equipment at the end of the work day; and purchasing ENERGY STAR^® qualified equipment, including but not limited to lighting, office equipment, commercial and residential quality kitchen equipment, vending and ice machines; and purchasing products certified by the U.S. EPA’s Water Sense^® program.

2.11 Recycling and Waste Management. Tenant covenants and agrees, at its sole cost and expense: (a) to comply with all present and future Governmental Requirements regarding the collection, sorting, separation, and recycling of garbage, trash, rubbish and other refuse (collectively, “trash”); (b) to comply with Landlord’s recycling policy, as stated in the Rules and Regulations (as such policy may be amended or supplemented from time to time), as part of Landlord’s sustainability practices where it may

be more stringent than applicable Governmental Requirements, including without limitation, recycling such categories of items designated by Landlord and transporting such items to any recycling areas designated by Landlord so long as they are within the Building; (c) to sort and separate its trash and recycling into such categories as are provided by Governmental Requirements or Landlord’s then-current sustainability practices; (d) that each separately sorted category of trash and recycling shall be placed in separate receptacles as directed and provided by Landlord; (e) that Landlord reserves the right to refuse to collect or accept from Tenant any waste that is not separated and sorted as required by Governmental Requirements, and to require Tenant to arrange for such collection at Tenant’s sole cost and expense, utilizing a contractor satisfactory to Landlord; and (f) that Tenant shall pay all costs, expenses, fines, penalties or damages that may be imposed on Landlord or Tenant by reason of Tenant’s failure to comply with the provisions of this paragraph 2.11.

SECTION 3: BASE RENT, ADDITIONAL RENT AND OTHER SUMS PAYABLE UNDER LEASE

3.1 Payment of Rental. Tenant agrees to pay Base Rent, Additional Rent and any other sum due under this Lease to Landlord without demand, deduction, credit, adjustment or offset of any kind or nature, in lawful money of the United States when due under this Lease, at the offices of Manager at Manager’s Address, or to such other party or at such other place as Landlord may from time to time designate in writing.

3.2 Base Rent. On execution of this Lease, Tenant shall pay to Landlord the amount specified in the definition of Prepaid Rent for the month specified in the definition of that term. Tenant agrees to pay the monthly installments of Base Rent to Landlord, without demand and in advance, on or before the first day of each calendar month of the Lease Term. The monthly Base Rent installment for any partial month at the beginning or end of the Lease Term shall be prorated. Base Rent for any partial calendar month following the expiration of the Abatement Period shall be paid on or before the first day of such partial calendar month.

3.3 Lease Security Provisions.

3.3.1 On execution of this Lease, as security for the full and faithful payment of all sums due under this Lease and the full and faithful performance of every covenant and condition of this Lease to be performed by Tenant, Tenant shall deliver a letter of credit in the amount of Five Hundred Thirteen Thousand Eight Hundred Thirty-Seven and 00/100 Dollars ($513,837.00) in favor of Landlord. The letter of credit initially delivered pursuant to this paragraph and all substitutions, replacements and renewals of it, must be consistent with and shall satisfy all the requirements in the letter of credit criteria set forth on Exhibit F hereto. The term “Letter of Credit” shall mean and refer to a letter of credit conforming to this subparagraph. If a Letter of Credit has not been delivered to and accepted by Landlord on or before the full execution of this Lease, at Landlord’s election, the failure to deliver such Letter of Credit may be treated by Landlord (a) as a condition subsequent to the effectiveness of this Lease such that this Lease shall be voidable by Landlord by notice to Tenant at any time prior to Landlord’s receipt of the Letter of Credit or (b) as Tenant Delay and an Event of Default. If Landlord elects to treat the failure to deliver the Letter of Credit on execution of this Lease as an Event of Default, Landlord may pursue all available rights and remedies, including the right to specific performance and the right to attach assets of Tenant.

3.3.2 Tenant shall have the right to reduce the amount of the Letter of Credit on or after each of the dates set forth below to the amount set forth opposite such date (each such date on which the amount of the Letter of Credit may first be reduced is referred to herein as a “Reduction Date”), provided that on each Reduction Date and on the date any such reduction is implemented (a) the Lease is in full force and effect, (b) all Base Rent and Additional Rent then due has been paid in full and no Event of Default has theretofore occurred at any time during the Lease Term, and (c) Landlord approves Tenant’s financial condition based upon Landlord’s standard underwriting criteria and a review of Tenant’s then current financial statements prepared in accordance with GAAP and certified to Landlord by an independent certified public accountant satisfactory to Landlord. Notwithstanding the foregoing, if Tenant does not otherwise have audited financials available, Landlord shall accept the foregoing certification required under clauses (c) from the Tenant’s chief financial officer.


Reduction Date	Required Amount of Letter of Credit		Reduction Amount
The first day of the twenty-fifth (25^th) full calendar month of the Lease Term	$	357,782.80	$	156,054.20
The first day of the thirty-seventh (37^th) full calendar month of the Lease Term	$	274,046.40	$	83,736.40

Except as set forth in the next sentence, if the conditions for reduction of the Letter of Credit are satisfied with respect to any Reduction Date, upon the written request of the Tenant, Landlord shall permit Tenant to replace or amend the Letter of Credit accordingly. If on any Reduction Date the Letter of Credit shall not be reduced because one (1) or more of the conditions set forth in clauses (a) through (c) above were not satisfied, the Letter of Credit shall not be reduced on any subsequent Reduction Date.

3.3.3 Landlord may draw on the Letter of Credit, in whole or in part at Landlord’s election, without advance notice to Tenant at any time or from time to time on or after (a) the occurrence of any Event of Default, (b) if Tenant, or anyone in possession of the Leased Premises through Tenant, holds over after the expiration or earlier termination of this Lease, (c) Landlord is given notice by the issuer of the Letter of Credit that it is terminating the Letter of Credit, (d) a confirming bank gives notice to Landlord that it will cease to act in that capacity, (e) the Letter of Credit expires on a specified date by its terms and is not renewed or replaced at least sixty (60) days in advance of its expiration date, (f) to the extent permitted by law, in the event any bankruptcy, insolvency, reorganization or any other debtor creditor proceeding is instituted by or against Tenant, or (g) the issuer of the letter of credit or the confirming bank thereof at any time fails to maintain the minimum credit rating required under the letter of credit criteria set forth on Exhibit F hereto and the Tenant fails to provide a substitute Letter of Credit which satisfies all of the terms and conditions hereof within twenty-one (21) days after notice from Landlord.

3.3.4 Landlord may apply any sum drawn on the Letter of Credit to amounts owing to Landlord under this Lease in such order and priority as Landlord elects in its absolute discretion. If any of the proceeds drawn on the Letter of Credit are not applied immediately to sums owing to Landlord under this Lease, Landlord may retain any such excess proceeds as a cash Lease Security Deposit for application, at Lender’s election, to future sums owing to Landlord under this Lease, in such order and priority as Landlord elects in its absolute discretion. Tenant shall, within fifteen (15) days after Landlord’s demand, restore the amount of the Letter of Credit drawn so that the Letter of Credit is restored to the original amount of the Letter of Credit. If Tenant does not restore the Letter of Credit to its original amount within the required time period, such non-restoration shall be considered an Event of Default.

3.3.5 Additionally, Landlord’s draw and application of all or any portion of the proceeds of the Letter of Credit shall not impair any other rights or remedies provided under this Lease or under applicable law and shall not be construed as a payment of liquidated damages. If Tenant shall have fully complied with all of the covenants and conditions of this Lease, the Letter of Credit shall be returned to Tenant or, if Landlord has drawn on the Letter of Credit, the remaining proceeds of the Letter of Credit which are in excess of sums due the Landlord shall be repaid to Tenant, without interest, within thirty (30) days after the expiration or termination of the Lease Term and delivery of possession of the Leased Premises to Landlord in accordance with this Lease.

3.3.6 On any request by Landlord made during the Lease Term, Tenant shall cooperate in accomplishing any reasonable modification of the Letter of Credit requested by Landlord. If the Letter of Credit should be lost, mutilated, stolen or destroyed, Tenant shall cooperate in obtaining the issuance of a replacement.

3.3.7 Tenant shall not assign or grant any security interest in the Letter of Credit and any attempt to do so shall be void and of no effect.

3.3.8 In the event of a sale or transfer of Landlord’s estate or interest in the Land and Building, Landlord shall have the right to transfer the Letter of Credit to the vendee or the transferee, Landlord shall pay any transfer fees charged by the issuing bank and Landlord shall thereafter be considered released by Tenant from all liability for the return of the Letter of Credit. Tenant shall cooperate in effecting such transfer.

3.3.9 No mortgagee or purchaser of any or all of the Building at any foreclosure proceeding brought under the provisions of any mortgage shall (regardless of whether the Lease is at the time in question subordinated to the lien of any mortgage) be liable to Tenant or any other person for any or all amounts drawn against the Letter of Credit or any other or additional lease security deposit or other payment made by Tenant under the provisions of this Lease), unless Landlord has actually delivered it in cash to such mortgagee or purchaser, as the case may be.

3.4 Additional Rent. Definitions of certain terms used in this paragraph are set forth in the last subparagraph of this paragraph entitled “Additional Rent”. Tenant agrees to pay to Landlord additional rent as computed in this paragraph (individually and collectively the “Additional Rent”):

3.4.1 Estimated Operating Costs. Tenant shall pay to Landlord as Additional Rent one-twelfth (1/12) of the amount, if any, by which the Estimated Operating Costs Allocable to the Premises exceeds the Base Amount Allocable to the Premises. This sum shall be paid in advance on or before the first day of each calendar month of the Lease Term following the end of the Base Year. Landlord shall furnish Tenant a written statement of Estimated Operating Costs Allocable to the Premises in advance of the commencement of each Year. If such written statement is furnished after the commencement of the Year, Tenant shall also make a retroactive lump-sum payment to Landlord equal to the monthly payment amount multiplied by the number of months during the Year (or as to the first Year during the Lease Term, after the Commencement Date) for which no payment was paid. Notwithstanding the foregoing, Landlord reserves the right, from time to time during each Year, to revise the Estimated Operating Costs Allocable to the Premises and upon notice to Tenant of such revision, Tenant shall adjust its payment to Landlord under this subparagraph 3.4.1 accordingly.

3.4.2 Actual Costs. After the close of each Year, Landlord shall deliver to Tenant a written statement setting forth the Operating Costs Allocable to the Premises during the preceding Year. If such Operating Costs Allocable to the Premises for any Year exceed the Estimated Operating Costs Allocable to the Premises paid by Tenant to Landlord pursuant to subparagraph 3.4.1 for such Year, Tenant shall pay the amount of such excess to Landlord within twenty (20) Business Days after receipt of such statement by Tenant. If such statement shows the Operating Costs Allocable to the Premises to be less than the Estimated Operating Costs Allocable to the Premises paid by Tenant to Landlord pursuant to subparagraph 3.4.1, then the amount of such overpayment shall be paid by Landlord to Tenant within twenty (20) Business Days following the date of such statement or, at Landlord’s option, shall be credited

towards the installment(s) of Additional Rent next coming due from Tenant.

3.4.3 Determination. The determination of Operating Costs Allocable to the Premises shall be made by Landlord.

3.4.4 Operating Cost Audit. Landlord shall maintain records concerning estimated and actual Operating Costs and Property Taxes for no less than twelve (12) months following the period covered by the statement or statements furnished Tenant, after which time Landlord may dispose of such records. Provided that no Event of Default exists, Tenant may, at Tenant’s sole cost and expense, cause a Qualified Person (defined below) to inspect Landlord’s records at the Manager’s office or, at Landlord’s option, at such other location where Landlord maintains such records. Such inspection, if any, shall be (a) conducted no more than once each calendar year, during Landlord’s normal business hours within ninety (90) calendar days after receipt of Landlord’s applicable written statement of Operating Costs for the previous year, upon first furnishing Landlord at least fifteen (15) Business Days prior written notice, and (b) limited to the Landlord’s records for the immediately preceding year. In no event shall Tenant be permitted to review Landlord’s records for any particular year more than once. As a condition to Tenant’s right to conduct such inspection, Tenant agrees (i) to promptly furnish Landlord (at Tenant’s cost) with a copy of all draft and final reports of Tenant’s examination of Landlord’s records, and (ii) except as required by applicable law, that neither Tenant nor any of Tenant’s Agents shall divulge the contents of Landlord’s records or the results of its examination to any third party. Any errors disclosed by the review shall be promptly corrected by Landlord; provided, however, that if Landlord disagrees with any such claimed errors, Landlord shall have the right to cause another review to be made by an auditor of Landlord’s choice. In the event the results of the review of records (taking into account, if applicable, the results of any additional review caused by Landlord) reveal that Tenant has overpaid obligations for a preceding period, the amount of such overpayment shall be paid by Landlord to Tenant within thirty (30) days following such review or, at Landlord’s option (except after the expiration of the Lease Term), credited towards the installment(s) of Base Rent and Additional Rent next coming due from Tenant to Landlord under the Lease. In the event that such results show that Tenant has underpaid its obligations for a preceding period, the amount of such underpayment shall be paid by Tenant to Landlord within thirty (30) days following such examination.

3.4.5 End of Term. If this Lease shall terminate on a day other than the last day of a Year, (a) Landlord shall estimate the Operating Costs Allocable to the Premises and Property Taxes Allocable to the Premises for such Year predicated on the most recent reliable information available to Landlord; (b) the amount determined under clause (a) of this sentence shall be prorated by multiplying such amount by a fraction, the numerator of which is the number of days within the Lease Term in such Year and the denominator of which is 360; (c) the Operating Costs Base Amount Allocable to the Premises shall be prorated in the manner described in clause (b); (d) the clause (c) amount (i.e., the prorated Operating Costs Base Amount Allocable to the Premises) shall be deducted from the clause (b) amount (i.e., the prorated Operating Costs Allocable to the Premises); (e) if the clause (d) amount exceeds the Estimated Operating Costs Allocable to the Premises paid by Tenant for the last Year in the Lease Term, then Tenant shall pay the excess to Landlord within ten (10) Business Days after Landlord’s delivery to Tenant of a statement for such excess; and (f) if the Estimated Operating Costs Allocable to the Premises paid by Tenant for the last Year in the Lease Term exceeds the clause (d) amount, then Landlord shall refund to Tenant the excess within the ten (10) Business Day period described in clause (e) if Tenant is not then in default of any of its obligations under this Lease. Landlord’s and Tenant’s obligations under this paragraph shall survive the expiration or other termination of this Lease.

Landlord reserves the right to install and activate separate metering of electricity, water or other utilities to the Premises at Landlord’s cost, in which case the Operating Costs Base Amount Allocable to the Premises and Operating Costs shall be adjusted accordingly.

3.5 Utilities.

3.5.1 Landlord shall have the right from time to time to select the company or companies providing electricity, gas, fuel, one or more categories of Telecommunication Services and any other utility services to the Building. Landlord reserves the right to change electricity providers for the Building at any time and to purchase green or renewable energy, provided that the cost of such green or renewable energy as passed through to Tenant shall not be materially greater than the then cost of other sources of energy then available on the market.. With the exception of water, sewer, electricity and HVAC, Tenant shall contract directly and pay for all utilities used on or from the Premises together with any taxes, penalties, surcharges or similar charges relating to such utilities. If any such service is not separately metered to the Premises or is not otherwise separately accounted for and billed to Tenant, the cost therefor shall be an Operating Cost under this Lease, provided that the cost of electric current for lights and convenience outlets shall be billed by Landlord to Tenant separately from, and in addition to, Operating Costs. Landlord estimates that the present cost of electric current for lights and convenience outlets (exclusive of any other purposes) shall be Two and 00/100 Dollars ($2.00) per rentable square foot. Landlord makes no warranty or representation that such cost will not increase during the Lease Term due to increases in electric rates and/or electricity consumption, as the case may be, provided that there shall be no ▇▇▇▇ up of the actual cost as billed by the utility provider.

3.5.2 Tenant acknowledges that space on the Building rooftop and in Building risers, equipment rooms and equipment closets is limited. If Tenant requires Telecommunication Services for the Premises other than from the provider or providers of Telecommunication Services selected by Landlord and whose Telecommunication Facilities are installed in or about the Building or on the rooftop of the Building, provision for alternate or supplemental Telecommunication Services or Telecommunication Facilities has been made in a license agreement accompanying and made part of this Lease. Unless otherwise required by law, neither Tenant, nor a provider of Telecommunication Services to Tenant, in the future shall be entitled to locate or install Telecommunication Facilities in, on or about the Building without (a) first obtaining Landlord’s advance, written consent (given in its absolute discretion) and (b) the advance execution by Landlord and Tenant of a satisfactory agreement granting a license to Tenant for such purposes and setting forth the scope, the additional rent, if any, royalties and the other terms and conditions of that license, and (c) Tenant negotiating and obtaining the right, if any is required, to bring such Telecommunication Facilities across public or private property to an approved entry point to the Building. The agreement referred to in clause (b) of the previous sentence shall be incorporated in and become part of this Lease. Any future application by Tenant for permission to locate or install Telecommunication Facilities shall (1) be in such form and shall be accompanied by such supporting information as the Landlord may reasonably require, (2) be subject to such procedures, regulations and controls as the Landlord may specify and (3) be accompanied by such payment as the Landlord may reasonably request to reimburse Landlord for its costs of evaluating and processing the application and in negotiating and preparing the agreement described earlier in this subparagraph.

3.5.3 Landlord shall in no case be liable or in any way be responsible for damages or loss to Tenant arising from the failure of, diminution of or interruption in electrical power, natural gas, fuel, Telecommunication Services, sewer, water, or garbage collection services, other utility service or building service of any kind to the Premises, unless such interruption in, deprivation of or reduction of any such service was caused by the gross negligence or willful misconduct of Landlord, its agents or contractors or by a failure in facilities, equipment or systems in the Landlord’s ownership. To the extent that Landlord bears any responsibility for any such interruption, deprivation or reduction in utility or building services to the Premises, Landlord’s responsibility and Tenant’s remedy shall be limited to an abatement in Base Rent for the period beginning with (a) the day which is five (5) Business Days after the date on which Tenant delivers notice to Landlord of such interruption, deprivation or reduction and that Tenant is being deprived of all reasonable use of the Premises and ending on (b) the date such interruption, deprivation or reduction which is Landlord’s responsibility is not causing Tenant to be deprived of all reasonable use of the Premises.

3.5.4 HVAC service shall be provided to the Premises Mondays through Fridays from 8:00 a.m. to 6:00 p.m., except for holidays (“Building Standard Hours”). Landlord shall provide HVAC service at times in addition to Building Standard Hours (“After-Hours HVAC”); provided, however, Tenant gives Landlord notice prior to 1:00 p.m. on the same day such After-Hours HVAC is required with respect to service on Business Days and prior to 1:00 p.m. on the immediately preceding Business Day with respect to service on non-Business Days. The charge to Tenant for After-Hours HVAC shall be at Landlord’s then-standard hourly rate in effect from time to time for After-Hours HVAC; provided, however there will be no charge for After-Hours HVAC on Saturdays between 8:00 AM and 12:00 noon (although Tenant must request same as set forth in the preceding sentence). Any HVAC service on holidays shall be considered After-Hours HVAC.

3.5.5 Tenant shall not install any supplemental HVAC, space heaters or other utilities or energy-intensive equipment (“Supplemental Utilities Equipment”) in the Premises without Landlord’s prior written consent, which consent shall not be unreasonably withheld and excluding any such equipment included in the Plans and Specifications approved by Landlord. In the event that Landlord consents in writing to such installation, Tenant shall be responsible, all at its sole cost and expense, for the installation, maintenance, and repair of any of Supplemental Utilities Equipment, and, at Landlord’s election, shall remove same from the Premises upon the expiration or termination of the Lease Term at Tenant’s sole cost and expense. If Tenant’s request for Landlord’s approval of any Supplemental Utilities Equipment is accompanied by a written request that Landlord identify all or any portion thereof that Landlord may require Tenant to remove upon the expiration or earlier termination of this Lease, Landlord shall identify such Supplemental Utilities Equipment (if any) by a written notice to Tenant given at the time of Landlord’s approval if, but only if, Tenant’s request for approval of such Supplemental Utilities Equipment is submitted with a notice at the top of the page having a heading in at least 12-point type, bold and all capital letters stating “LANDLORD’S APPROVAL MUST IDENTIFY ANY SUPPLEMENTAL UTILITIES EQUIPMENT WHICH LANDLORD MAY REQUIRE TENANT TO REMOVE UPON THE EXPIRATION OR EARLIER TERMINATION OF THIS LEASE”, and Tenant shall have no obligation to remove any Supplemental Utilities Equipment which has not been so identified by Landlord. Tenant agrees that it will maintain and repair any Supplemental Utilities Equipment, and major components thereof, in first-class condition, and to the extent applicable any such equipment will be operated on sensors or timers that limit the operation of such Supplemental Utilities Equipment to hours of occupancy in the areas immediately adjacent to the occupying personnel. Tenant shall, at its sole cost and expense, enter into a regularly scheduled preventative maintenance/service contract with a maintenance contractor or the seller of any such Supplemental Utilities Equipment, and upon Landlord’s reasonable request, Tenant will provide Landlord with reasonable evidence of such maintenance and repair. Upon Landlord’s request, at reasonable times and upon prior notice to Tenant (except in the event of an emergency, where no notice is required) Landlord shall have the right to inspect, on not less than a monthly basis, the aforementioned Supplemental Utilities Equipment and major components provided Landlord shall use commercially reasonable efforts to minimize Landlord’s interference with Tenant’s business. Tenant shall not permit any Supplemental Utilities Equipment to disturb or interfere with any of the Building’s systems or any other tenant in the Building, and Tenant will remove, at Tenant’s sole cost and expense, any such Supplemental Utilities Equipment at Landlord’s direction in the event of such

disturbance or interference. Landlord reserves the right to separately submeter (or cause Tenant to separately submeter) any Supplemental Utilities Equipment, all at Tenant’s sole cost and expense. Notwithstanding anything herein to the contrary, in the event that any Supplemental Utilities Equipment is required to be removed from the Premises by Tenant pursuant to the terms of this paragraph 3.5.5, Landlord may perform such removal at its election, and Tenant shall reimburse Landlord for any costs relating thereto, or in the event that Tenant performs such removal, Tenant shall be responsible to Landlord for any damage caused to the Premises or Building in connection therewith.

3.5.6 To the extent reasonably available to Tenant, Tenant shall be required to submit to Landlord any electricity consumption data and costs in a format deemed reasonably acceptable by Landlord.

3.6 Holdover. Tenant is not authorized to hold over beyond the expiration or earlier termination of the Lease Term. If Landlord consents to a holdover and no other agreement is reached between Tenant and Landlord concerning the duration and terms of the Holdover, Tenant’s holdover shall be a month-to-month tenancy. During such tenancy, Tenant shall pay to Landlord one hundred fifty percent (150%) of Base Rent in effect on the expiration or termination of the Lease Term plus all Additional Rent and other sums payable under this Lease for the first sixty (60) days of such holdover and thereafter twice the rate of Base Rent in effect on the expiration or termination of the Lease Term plus all Additional Rent and other sums payable under this Lease, and shall be bound by all of the other covenants and conditions specified in this Lease, so far as applicable. If the Landlord does not consent to the Tenant’s remaining in possession, Landlord shall have all the rights and remedies provided for by law and this Lease, including the right to recover consequential damages suffered by Landlord in the event of Tenant’s wrongful refusal to relinquish possession of the Premises. The Base Rent applicable for the period that Tenant wrongfully remains in possession shall in be increased to one hundred fifty percent (150%) of Base Rent in effect on the expiration or termination of the Lease Term for the first sixty (60) days of such holdover and thereafter to twice the rate of Base Rent in effect on the expiration or termination of the Lease Term.

3.7 Late Charge. If Tenant fails to make any payment of Base Rent, Additional Rent or other amount when due under this Lease, a late charge is immediately due and payable by Tenant equal to five percent (5%) of the amount of any such payment. Landlord and Tenant agree that this charge compensates Landlord for the administrative costs caused by the delinquency. The parties agree that Landlord’s damage would be difficult to compute and the amount stated in this paragraph represents a reasonable estimate of such damage. Assessment or payment of the late charge contemplated in this paragraph shall not excuse or cure any Event of Default or breach by Tenant under this Lease or impair any other right or remedy provided under this Lease or under law.

3.8 Default Rate. Any Base Rent, Additional Rent or other sum payable under this Lease which is not paid when due shall bear interest at a rate equal to the lesser of: (a) the published prime or reference rate then in effect at a national banking institution designated by Landlord (the “Prime Rate”), plus four (4) percentage points, or (b) the maximum rate of interest per annum permitted by applicable law (the “Default Rate”), but the payment of such interest shall not excuse or cure any Event of Default or breach by Tenant under this Lease or impair any other right or remedy provided under this Lease or under law.

Except in the case of an emergency or as required by Governmental Requirements, Landlord shall use commercially reasonable efforts to minimize Landlord’s interference with Tenant’s business in connection with the rights reserved

in this Paragraph 4.3.1

4.3.2 Landlord has no duty or obligation to provide any security services in, on or around the Premises, Land or Building, and Tenant recognizes that security services, if any, provided by Landlord will be for the sole benefit of Landlord and the protection of Landlord’s property and under no circumstances shall Landlord be responsible for, and Tenant waives any rights with respect to, Landlord providing security or other protection for Tenant or Tenant’s Agents or property in, on or about the Premises, Land or Building. Subject to Landlord’s prior approval, Tenant may, at its sole cost and expense, install, establish and maintain security services within the Premises; provided that, such security services (including any apparatus, facilities, equipment or people utilized in connection with the provision of such security services) comply with the Governmental Requirements and shall not cause the Building to be out of compliance with the Governmental Requirements. Notwithstanding the foregoing, any such security services installed, established or maintained by Tenant must not affect or impact any portion of the Building or the Land other than the Premises and shall not in any way limit or interfere with Landlord’s ability to exercise its rights as provided in the paragraph captioned “Access”. Tenant’s rights under this subparagraph are subject to all the obligations, limitations and requirements as set forth in the paragraphs captioned “Tenant Alterations” and “Tenant’s Work Performance”.

4.3.3 As long as (a) the Lease Term remains in full force and effect, (b) the Landlord continues to own all of the buildings presently comprising the Park, and (c) The Endurance International Group, Inc. or a Permitted Transferee is actually using and occupying at least seventy-five percent (75%) of the Premises, Landlord shall maintain, or cause to be maintained, a cafeteria or other food service operation and a fitness room in the Park, each of which shall be open during such days and hours as reasonably determined from time to time by Landlord. The fitness room shall not be required to be staffed, nor shall towel services be provided. During the hours such facilities are open during the Lease Term, Tenant and its employees shall have nonexclusive access to the cafeteria and the non-exclusive right to use the fitness room in common with Landlord and all others to whom Landlord has granted or may hereafter grant rights, provided that any person’s use of the fitness room shall be at such person’s own risk and may be conditioned on such person signing a waiver of liability in such form as the Landlord from time to time may require. Tenant’s use of such common areas shall be subject to such reasonable regulations as Landlord may from time to time impose and the rights of Landlord set forth herein. The provisions of this Paragraph 4.3.3 shall terminate and be of no further force or effect at such time as the Landlord ceases to own each and all of the buildings presently comprising the Park.

4.4 Tenant Alterations. Tenant shall not make any alterations, additions or improvements in or to the Premises, or make changes to locks on doors, or add, disturb or in any way change any floor covering, wall covering, fixtures, plumbing, wiring or Telecommunication Facilities (individually and collectively “Tenant Alterations”), without first obtaining the consent of Landlord, which consent shall not be unreasonably withheld, provided such Tenant Alterations are entirely within the Premises and do not impact any structural components of the Building or any building systems. Notwithstanding the foregoing, so long as Tenant complies with all applicable Governmental Requirements and other terms and conditions of this Lease, upon at least five (5) Business Days advance written notice to Landlord but without Landlord’s consent, Tenant may make interior non-structural Tenant Alterations with an aggregate cost which does not exceed Twenty-Five Thousand Dollars ($25,000.00) in any period of twelve (12) consecutive calendar months which (a) are entirely cosmetic or functional in nature (such as painting and carpeting, shelving or cubicles), (b) do not affect any of the Building’s mechanical, HVAC, electrical, plumbing or other systems, (c) do not involve the installation or demolition of any interior wall or door, and (d) do not require the issuance of any permit by any Governmental Agency (Tenant Alterations satisfying all of the foregoing items (a) through (d) are referred to herein as “Permitted Alterations”). Tenant shall deliver to Landlord full and complete plans and specifications for any proposed Tenant Alterations and, if consent by Landlord is given, all such work shall be performed at Tenant’s expense by Landlord or by Tenant at Landlord’s election. Tenant shall pay to Landlord all costs incurred by Landlord for any architecture, engineering, supervisory and/or legal services in connection with any Tenant Alterations, including, without limitation, Landlord’s review of the Plans and Specifications. Without limiting the generality of the foregoing, Landlord may require Tenant (if Tenant has elected to perform the Tenant Alterations), at Tenant’s sole cost and expense, to obtain and provide Landlord with proof of insurance

coverage and a payment and performance bond, in forms, amounts and by companies acceptable to Landlord, provided that no payment and performance bond shall be required for any Permitted Alterations. Should Tenant make any alterations without Landlord’s prior written consent (other than Permitted Alterations), or without satisfaction of any conditions established by Landlord, Landlord shall have the right, in addition to and without limitation of any right or remedy Landlord may have under this Lease, at law or in equity, to require Tenant to remove some or all of Tenant Alterations, or at Landlord’s election, Landlord may remove such Tenant Alterations and restore the Premises at Tenant’s expense. Nothing contained in this paragraph or the paragraph captioned “Tenant’s Work Performance” shall be deemed a waiver of the provisions of the paragraph captioned “Mechanic’s Liens”.

4.5 Tenant’s Work Performance. If Tenant elects to perform the Tenant Alterations, Landlord may, in its absolute discretion, require that Tenant provide a payment and performance bond to cover the entire work to be performed, which bond must be in form, amount and by a company acceptable to Landlord. Notwithstanding the foregoing, Landlord shall not require Tenant to obtain a payment and performance bond for any Permitted Alterations. Any Tenant Alterations to be performed under this paragraph shall be performed by contractors employed by Tenant under one or more construction contracts, in form and content approved in advance in writing by Landlord. Approval shall be subject to Landlord’s reasonable discretion and shall include a requirement that the prime contractor and the respective subcontractors of any tier performing the Tenant Alterations: (a) be parties to, and bound by, a collective bargaining agreement with a labor organization affiliated with the Building and Construction Trades Council of the AFL-CIO applicable to the geographic area in which the Building is located and to the trade or trades in which the work under the contract is to be performed and (b) employ only members of such labor organizations to perform work within their respective jurisdictions. The previous sentence shall apply whether it is Landlord or Tenant performing or contracting for any such alterations, additions, improvements or installations. Waivers or exceptions to the requirement in the third sentence of this paragraph may be given only in writing by Landlord. With the specific, prior written approval of Landlord, which may be withheld in Landlord’s sole and absolute discretion, in clause (a) of the third sentence of this paragraph the following substitutions may be made: (1) a project labor agreement in place of a collective bargaining agreement, and (2) an independent, nationally recognized labor organization in place of a labor organization affiliated with the Building and Construction Trades Council of the AFL-CIO. Tenant’s contractors, workers and suppliers shall work in harmony with and not interfere with workers or contractors of Landlord or other tenants of Landlord. If Tenant’s contractors, workers or suppliers do, in the good faith opinion of Landlord, cause such disharmony or interference, Landlord’s consent to the continuation of such work may be withdrawn upon written notice to Tenant. All Tenant Alterations shall be (1) completed in accordance with the plans and specifications approved by Landlord; (2) completed in accordance with all Governmental Requirements; (3) carried out promptly in a good and workmanlike manner; (4) of all new materials; and (5) free of defect in materials and workmanship. In addition to the above requirements, Tenant shall use commercially reasonable efforts to contract for services to be performed in or about the Premises with companies which are a Responsible Contractor. A “Responsible Contractor” is defined as a contractor or subcontractor who pays workers a fair wage and Fair Benefits as evidenced by payroll and employee records and who complies with a service-disabled veteran business policy. “Fair Benefits” are defined as including employer-paid family health care coverage, pension benefits, and apprenticeship programs. Any and all Tenant Alterations that affects at least fifty percent (50%) of the Premises will be performed in accordance with Landlord’s sustainability practices, (as same may be in effect or amended or supplemented from time to time) and any Green Agency Ratings, as the same may change from time to time. Tenant further agrees to engage a qualified third party LEED or Green Globe Accredited Professional or similarly qualified professional during the design phase through implementation of any Tenant Alterations covered by the preceding sentence, in order to review all plans, material procurement, demolition, construction and waste management procedures and Tenant shall endeavor to ensure that the foregoing are in full conformance with Landlord’s sustainability practices, as aforesaid. Tenant also shall endeavor to construct the Premises to certified LEED CI standards, and Tenant shall have the right to request descriptions of recent commissioning and energy audits that the Landlord has undertaken to understand and retrofit building systems to the green/sustainable level referenced above. Tenant shall pay for all damage to the Premises, Building and Land caused by Tenant or Tenant’s Agents. Tenant shall indemnify, defend and hold harmless Landlord and Landlord’s Agents from any Claims arising as a result of the Tenant Alterations or any defect in design, material or

workmanship of any Tenant Alterations, excluding Claims for defective workmanship (but not design) if and to the extent that the Landlord performed the work.

4.6 Surrender of Possession. Tenant shall, at the expiration or earlier termination of this Lease, surrender and deliver the Premises to Landlord in as good condition as when received by Tenant from Landlord or as later improved, reasonable use and wear excepted, and free from all tenancies or occupancies by any person.

4.7 Removal of Property. Upon expiration or earlier termination of this Lease, Tenant may remove its personal property, trade fixtures, office supplies and office furniture and equipment if (a) such items are readily moveable and are not permanently attached to the Premises; (b) such removal is completed prior to the expiration or earlier termination of this Lease; (c) no Event of Default exists at the time of such removal; and (d) Tenant immediately repairs all damage caused by or resulting from such removal. All other property in the Premises and any Tenant Alterations (including, wall-to-wall carpeting, paneling, wall covering, lighting fixtures and apparatus or Telecommunication Facilities or any other article affixed to the floor, walls, ceiling or any other part of the Premises or Building) shall become the property of Landlord and shall remain upon and be surrendered with the Premises; provided, however, at Landlord’s sole election, Tenant shall be obligated, at its sole cost and expense, to remove all (or such portion as Landlord shall designate) of the Tenant Alterations (including Telecommunication Facilities), repair any damages resulting from such removal and return the Premises to the same condition as existed prior to such Tenant Alterations. Notwithstanding the foregoing, if Tenant’s submission of its plans and specifications to Landlord for approval of any Tenant Alterations requiring Landlord’s approval is accompanied by a written request that Landlord identify any Tenant Alterations that Landlord may require Tenant to remove upon the expiration or earlier termination of this Lease, Landlord shall identify such Tenant Alterations (if any) by a written notice (a “Removal Notice”) to Tenant given at the time of Landlord’s approval of such plans and specifications if, but only if, Tenant’s request for approval of such plans and specifications is submitted with a notice at the top of the page having a heading in at least 12-point type, bold and all capital letters stating “LANDLORD’S APPROVAL MUST IDENTIFY ANY TENANT ALTERATIONS WHICH LANDLORD MAY REQUIRE TENANT TO REMOVE UPON THE EXPIRATION OR EARLIER TERMINATION OF THIS LEASE”, and Tenant shall have no obligation to remove any Tenant Alterations which have not been so identified by Landlord. In all events, unless otherwise agreed in writing by Landlord, Tenant shall be required to remove all wiring and cabling installed in the Building by or at the request of the Tenant. Tenant waives all rights to any payment or compensation for such Tenant Alterations (including Telecommunication Facilities). If Tenant shall fail to remove any of its property from the Premises, Building or Land at the expiration or earlier termination of this Lease or when Landlord has the right of re-entry, Landlord may, at its option, remove and store such property at Tenant’s expense without liability for loss of or damage to such property, such storage to be for the account and at the expense of Tenant. Tenant shall pay all reasonable costs incurred by Landlord within five (5) Business Days after demand for such payment. If Tenant fails to pay the cost of storing any such property, Landlord may, at its option, after it has been stored for a period of twenty (20) Business Days or more, sell or permit to be sold, any or all such property at public or private sale (and Landlord may become a purchaser at such sale), in such manner and at such times and places as Landlord in its sole discretion may deem proper, without notice to Tenant, and Landlord shall apply the proceeds of such sale: first, to the cost and expense of such sale, including reasonable attorney’s fees actually incurred; second, to the payment of the costs or charges for storing any such property; third, to the payment of any other sums of money which may then be or later become due Landlord from Tenant under this Lease; and, fourth, the balance, if any, to Tenant.

4.8 Access.

4.8.1 Tenant shall permit Landlord and Landlord’s Agents to enter into the Premises at any time on at least one (1) Business Day’s notice (except in case of emergency in which case no notice shall be required), for the purpose of inspecting the same or for the purpose of repairing, altering or improving the Premises or the Building. Nothing contained in this paragraph shall be deemed to impose any obligation upon Landlord not expressly stated elsewhere in this Lease. When reasonably necessary, Landlord may temporarily close Building or Land entrances, Building doors or other facilities, without

liability to Tenant by reason of such closure and without such action by Landlord being construed as an eviction of Tenant or as relieving Tenant from the duty of observing or performing any of the provisions of this Lease. Landlord shall have the right to enter the Premises at any time during last twelve (12) months of the Lease Term and at any time during the Lease Term that an Event of Default exists for the purpose of showing the Premises to prospective tenants and to erect on the Premises a suitable sign indicating the Premises are available. Tenant shall give written notice to Landlord at least twenty (20) Business Days prior to vacating the Premises and shall arrange to meet with Landlord for a joint inspection of the Premises prior to vacating. In the event of Tenant’s failure to give such notice or arrange such joint inspection, Landlord’s inspection at or after Tenant’s vacating the Premises shall be conclusively deemed correct for purposes of determining Tenant’s responsibility for repairs and restoration.

4.8.2 Except in the case of an emergency and subject to the terms and conditions hereof, Tenant shall have access to the Premises twenty-four (24) hours a day, seven (7) days a week subject to Landlord’s reasonable building security procedures and requirements. Landlord shall not be liable for the consequences of acting in good faith to admit by passkey, or to refuse to admit to the Premises, Tenant or any of Tenant’s Agents, or other persons claiming the right of admittance.

4.9 Damage or Destruction.

4.9.1 If the Premises are damaged by fire, earthquake or other casualty, Tenant shall give immediate written notice (a “Casualty Notice”) thereof to Landlord. If Landlord estimates that the damage can be repaired in accordance with the then-existing Governmental Requirements within one hundred—twenty (120) Business Days after Landlord is notified by Tenant of such damage and if there are sufficient insurance proceeds available to repair such damage, then Landlord shall proceed with reasonable diligence to restore the Premises to substantially the condition which existed prior to the damage and this Lease shall not terminate. If, in Landlord’s estimation, the damage cannot be repaired within such 120 Business Day period or if there are insufficient insurance proceeds available to repair such damage, Landlord may elect in its absolute discretion to either: (a) terminate this Lease or (b) restore the Premises to substantially the condition which existed prior to the damage and this Lease will continue. If Landlord restores the Premises under this paragraph, then Landlord shall use commercially reasonable efforts to proceed toward completion of the restoration and (1) at Landlord’s option, the Lease Term shall be extended for the time required to complete such restoration, (2) Tenant shall pay to Landlord, upon demand, Tenant’s Pro Rata Share of any applicable deductible amount specified under Landlord’s insurance and (3) notwithstanding anything to the contrary contained herein, Landlord shall not be required to repair or restore any Specialty Tenant Improvements, Tenant Alterations (including Telecommunication Facilities), or any or all furniture, fixtures, equipment, inventory, improvements or other property which was in or about the Premises at the time of the damage and was not owned by Landlord. In the case of damage to the Premises or the Building which is of a nature or extent that (a) such damage materially interferes with Tenant’s access to or use of a portion but not all of the Premises (such portion being referred to herein as the “Materially Affected Premises”), Base Rent and Additional Rent otherwise payable hereunder shall be abated by the percentage that the rentable area of the Materially Affected Premises bears to the total rentable area of the Premises, for the period beginning on the date of the Casualty Notice and ending on the earlier of (i) the date that Landlord has substantially completed its repairs to the Materially Affected Premises and (ii) the date that Tenant uses any portion of the Materially Affected Premises for the conduct of its business, or (b) such damage materially interferes with Tenant’s access to or use of the entire Premises, all Base Rent and Additional Rent otherwise payable hereunder shall be abated for the period beginning on the date of the Casualty Notice and ending on the earlier of (i) the date that Landlord has substantially completed its repairs to the Premises and (ii) the date that Tenant uses any portion of the Premises for the conduct of its business. Except for the abatement of Base Rent and Additional Rent if and to the extent provided herein, Tenant agrees to look to the provider of Tenant’s insurance for coverage for the loss of Tenant’s use of the Premises and any other related losses or damages incurred by Tenant during any reconstruction period. Notwithstanding the foregoing, if the Premises have not been restored to the condition required by Landlord hereunder on or before the date which is twelve (12) months after Landlord’s receipt of the Casualty Notice (which date in shall be extended one day for each day of delay caused by any act or omission of Tenant and for events of Force Majeure as contemplated in Paragraph 6.8 hereof), then Tenant shall have the right to

cancel this Lease upon not less than thirty (30) days prior written notice given to the Landlord within ten (10) Business Days after the expiration of such period (time being of the essence), provided such cancellation shall be void and this Lease shall continue in full force and effect in the event that substantial completion of the Premises is achieved within such thirty (30) day period (which date shall be extended one day for each day of delay caused by any act or omission of Tenant and for events of Force Majeure as contemplated in Paragraph 6.8 hereof).

4.9.2 If the Building is damaged by fire, earthquake or other casualty and more than fifty percent (50%) of the Building is rendered untenantable, without regard to whether the Premises are affected by such damage, Landlord may in its absolute discretion and without limiting any other options available to Landlord under this Lease or otherwise, elect to terminate this Lease by notice in writing to Tenant within forty (40) Business Days after the occurrence of such damage if Landlord is also terminating the leases of other tenants in the Building who are similarly situated to Tenant. Such notice shall be effective thirty (30) Business Days after receipt by Tenant unless a later date is set forth in Landlord’s notice.

4.9.3 Notwithstanding anything contained in this Lease to the contrary, if there is damage to the Premises or Building and the holder of any indebtedness secured by a mortgage or deed of trust covering any such property requires that the insurance proceeds be applied to such indebtedness or if the insurance proceeds are otherwise inadequate to complete the repair of the damages to the Premises, the Building or both, then Landlord shall have the right to terminate this Lease by delivering written notice of termination to Tenant within fifteen (15) Business Days after Landlord is notified of such requirement.

4.9.4 Notwithstanding the foregoing, if the Premises or the Building are wholly or partially damaged or destroyed within the final six (6) months of the Term, to such an extent that the cost of restoration would exceed fifty percent (50%) of the replacement cost of the Premises and/or the Building in its or their entirety at the time such damage or destruction occurs, Landlord may, at its option, elect to terminate this Lease upon written notice to Tenant within forty (40) Business Days following such damage or destruction. Further, notwithstanding the foregoing, if the Premises are wholly or partially damaged or destroyed within the final six (6) months of the Lease Term to such an extent that the cost of restoration would exceed fifty percent (50%) of the replacement cost of the Premises in its entirety at the time such damage or destruction occurs and Landlord estimates that less than three (3) months will remain in the Lease Term on the date by which Landlord estimates completion of its restoration work, then Tenant also may terminate this Lease upon written notice to Landlord within thirty (30) days following such damage or destruction.

4.10 Condemnation. If all of the Premises, or such portions of the Building as may be required for the Tenant’s reasonable use of the Premises, are taken by eminent domain or by conveyance in lieu thereof, this Lease shall automatically terminate as of the date the physical taking occurs, and all Base Rent, Additional Rent and other sums payable under this Lease shall be paid to that date. In case of taking of a part of the Premises or a portion of the Building not required for the Tenant’s reasonable use of the Premises, then this Lease shall continue in full force and effect and the Base Rent shall be equitably reduced based on the proportion by which the floor area of the Premises is reduced, such reduction in Base Rent to be effective as of the date the physical taking occurs. Additional Rent and all other sums payable under this Lease shall not be abated but Tenant’s Pro Rata Share shall be redetermined as equitable under the circumstances. Landlord reserves all rights to damages or awards for any taking by eminent domain relating to the Premises, Building, Land and the unexpired term of this Lease. Tenant assigns to Landlord any right Tenant may have to such damages or award and Tenant shall make no claim against Landlord for damages for termination of its leasehold interest or interference with Tenant’s business. Tenant shall have the right, however, to claim and recover from the condemning authority compensation for any loss to which Tenant may be entitled for Tenant’s moving expenses or other relocation costs; provided that, such expenses or costs may be claimed only if they are awarded separately in the eminent domain proceedings and not as a part of the damages recoverable by Landlord.

4.11 Parking. Tenant shall have the nonexclusive privilege to use parking spaces on the Land in common with other tenants of Landlord, but only in areas reasonably designated by Landlord and only on

a first-come-first-served basis. Tenant’s parking privileges shall be subject to the rules and regulations relating to parking adopted by Landlord from time to time. Landlord shall have the right to grant designated, reserved parking stalls to other tenants in the Building. In no event shall the number of parking stalls used by Tenant and Tenant’s Agents exceed the number of stalls allocated to Tenant in the definition of the Parking Ratio, provided, however, that nothing in this sentence shall be deemed to alter the first-come-first-served basis of parking as provided in this paragraph 4.11. Landlord shall have no obligation whatsoever to monitor or police the parking or other common areas, except that Landlord shall use commercially reasonable efforts to monitor and enforce the use of the parking areas with respect to the parking ratio stated in this Lease.

4.12 Indemnification.

4.12.1 Tenant shall indemnify, defend and hold harmless Landlord and Landlord’s Agents from and against any and all Claims, arising in whole or in part out of (a) the possession, use or occupancy of the Premises or the business conducted in the Premises, (b) any act, omission or negligence of Tenant or Tenant’s Agents, or (c) any breach or default under this Lease by Tenant.

4.12.2 Except as specified below, neither Landlord nor Landlord’s Agents shall, to the extent permitted by law, have any liability to Tenant, or to Tenant’s Agents, for (1) any Claims arising out of any cause whatsoever, including repair to any portion of the Premises; (2) interruption in or interference with the use of the Premises or any equipment therein; (3) any accident or damage resulting from any use or operation by Landlord, Tenant or any person or entity of heating, cooling, electrical, sewerage or plumbing equipment or apparatus or Telecommunication Facilities; (4) termination of this Lease by reason of damage to the Premises or Building; (5) fire, robbery, theft, vandalism, mysterious disappearance or a casualty of any kind or nature; (6) actions of any other tenant of the Building or of any other person or entity; (7) inability to furnish any service required of Landlord as specified in this Lease; or (8) leakage in any part of the Premises or the Building from rain, ice or snow, or from drains, pipes or plumbing fixtures in the Premises or the Building. Landlord shall be responsible only for Claims arising solely out of the negligence or willful misconduct of Landlord in failing to repair or maintain the Building as required by this Lease after notice by Tenant as required by the paragraph captioned “Maintenance and Repair by Landlord”; but in no event shall Landlord’s responsibility extend to any interruption to Tenant’s business or any indirect or consequential losses suffered by Tenant or Tenant’s Agents or extend beyond Landlord’s responsibility as set forth in the paragraph entitled “Utilities” when that paragraph is applicable. Subject to the foregoing limitations and exclusions and all other terms and conditions of this Lease, Landlord shall indemnify, defend and hold harmless Tenant from and against any and all Claims of third parties, to the extent arising out of (a) any willful misconduct or negligent or unlawful act or omission of Landlord or Landlord’s Agents, or (b) any breach or default under this Lease by Landlord, but in no event shall Landlord’s responsibility under the foregoing clauses (a) or (b) extend to any interruption to Tenant’s business or any indirect or consequential losses. The obligations of this paragraph shall be subject to the paragraph captioned “Waiver of Subrogation”.

4.13 Tenant Insurance.

4.13.1 Tenant shall, throughout the Lease Term, at its own expense, keep and maintain in full force and effect the following policies, each of which shall be endorsed as needed to provide that the insurance afforded by these policies is primary and that all insurance carried by Landlord is strictly excess and secondary and shall not contribute with Tenant’s liability insurance:

(a) A policy of commercial general liability insurance, including a contractual liability endorsement covering Tenant’s obligations under the paragraph captioned “Indemnification”, insuring against claims of bodily injury and death or property damage or loss with a combined single limit at the Commencement Date of this Lease of not less than Two Million Dollars ($2,000,000.00), which limit shall be reasonably increased during the Lease Term at Landlord’s request to reflect both increases in liability exposure arising from inflation as well as from changing use of the Premises or changing legal liability standards, which policy shall be payable on an “occurrence” rather than a “claims made” basis, and which policy names Landlord, Bentall ▇▇▇▇▇▇▇ (U.S.) LP, the Manager and, at Landlord’s request, Landlord’s

mortgage lender(s) and/or investment advisors, as additional insureds;

(b) A policy of extended property insurance (which is commonly called “all risk”) covering all Specialty Tenant Improvements, Tenant Alterations (including Telecommunication Facilities), and any and all furniture, fixtures, equipment, inventory, improvements and other property in or about the Premises which is not owned by Landlord, for one hundred percent (100%) of the then current replacement cost of such property;

(c) Business interruption insurance in an amount sufficient to cover costs, damages, lost income, expenses, Base Rent, Additional Rent and all other sums payable under this Lease, should any or all of the Premises not be usable for a period of up to twelve (12) months;

(d) A policy of worker’s compensation insurance as required by applicable law and employer’s liability insurance with limits of no less than One Million Dollars ($1,000,000.00); and

(e) If applicable, unless covered under Landlord’s commercial general liability insurance required under Paragraph 4.13.1(a) hereof, a policy of comprehensive automobile liability insurance, including loading and unloading, and covering owned, non-owned and hired vehicles, with limits of no less than One Million Dollars ($1,000,000.00) per occurrence.

4.13.2 All insurance policies required under this paragraph shall be with companies reasonably approved by Landlord and each policy shall provide that it is not subject to cancellation, lapse or reduction in coverage except after thirty (30) days’ written notice to Landlord. Prior to the Commencement Date and from time to time thereafter, Tenant shall deliver to Landlord, Bentall ▇▇▇▇▇▇▇ (U.S.) LP, the Manager, and, at Landlord’s request, any other parties hereunder required to be named as additional insureds, certificates evidencing the existence and amounts of all such policies.

4.13.3 If Tenant fails to acquire or maintain any insurance or provide any certificate required by this paragraph, Landlord may, but shall not be required to, obtain such insurance or certificates and the costs associated with obtaining such insurance or certificates shall be payable by Tenant to Landlord on demand.

4.14 Landlord’s Insurance. Landlord shall, throughout the Lease Term, keep and maintain in full force and effect:

4.14.1 A policy of commercial general liability insurance, insuring against claims of bodily injury and death or property damage or loss with a combined single limit at the Commencement Date of not less than One Million Dollars ($1,000,000.00) per occurrence and Two Million Dollars ($2,000,000.00) in the aggregate, which policy shall be payable on an “occurrence” rather than a “claims made” basis;

4.14.2 A policy of extended property insurance (what is commonly called “all risk”) covering the Building and Landlord’s personal property, if any, located on the Land in the amount of one hundred percent (100%) of the then current replacement value of such property; and

4.14.3 Landlord may, but shall not be required to, maintain other types of insurance as Landlord deems appropriate, including but not limited to, property insurance coverage for earthquakes and floods in such amounts as Landlord deems appropriate. Such policies may be “blanket” policies which cover other properties owned by Landlord.

4.15 Waiver of Subrogation. Notwithstanding anything in this Lease to the contrary, Landlord and Tenant hereby each waive and release the other from any and all Claims or any loss or damage that may occur to the Land, Building, Premises, or personal property located therein, by reason of fire or other casualty regardless of cause or origin, including the negligence or misconduct of Landlord, Tenant, Landlord’s Agents or Tenant’s Agents, but only to the extent of the insurance proceeds paid to such releasor under its policies of insurance or, if it fails to maintain the required policies, the insurance

proceeds that would have been paid to such releasor if it had maintained such policies. Each party to this Lease shall promptly give to its insurance company written notice of the mutual waivers contained in this subparagraph, and shall cause its insurance policies to be properly endorsed, if necessary, to prevent the invalidation of any insurance coverages by reason of the mutual waivers contained in this subparagraph.

4.16 Assignment and Subletting by Tenant.

4.16.1 Tenant shall not have the right to assign, transfer, mortgage or encumber this Lease in whole or in part, nor sublet the whole or any part of the Premises, nor allow the occupancy of all or any part of the Premises by another, without first obtaining Landlord’s written consent, which consent shall not be unreasonably withheld provided no Event of Default then exists. Notwithstanding any permitted assignment or subletting, Tenant shall at all times remain directly, primarily and fully responsible and liable for the payment of all sums payable under this Lease and for compliance with all of its other obligations as tenant under this Lease. Landlord’s acceptance of Base Rent, Additional Rent or any other sum from any assignee, sublessee, transferee, mortgagee or encumbrance holder shall not be deemed to be Landlord’s approval of any such conveyance. Upon the occurrence of an Event of Default, if the Premises or any part of the Premises are then subject to an assignment or subletting, Landlord may, at its option, collect directly from such assignee or subtenant all rents becoming due to Tenant under such assignment or sublease and apply such rents against any sums due to Landlord from Tenant under this Lease. No such collection shall be construed to constitute a novation or release of Tenant from the further performance of Tenant’s obligations under this Lease. Landlord’s right of direct collection shall be in addition to and not in limitation of any other rights and remedies provided for in this Lease or at law. Tenant makes an absolute assignment to Landlord of such assignments and subleases and any rent, lease security deposits and other sums payable under such assignments and subleases as collateral to secure the performance of the obligations of Tenant under this Lease.

4.16.2 In the event Tenant desires to assign this Lease or to sublet all or any portion of the Premises, Tenant shall give written notice of such desire to Landlord setting forth the name of the proposed subtenant or assignee, the proposed term, the nature of the proposed subtenant’s or assignee’s business to be conducted on the Premises, the rental rate, and any other particulars of the proposed subletting or assignment that Landlord may reasonably request. Without limiting the preceding sentence, Tenant shall also provide Landlord with: (a) such financial information as Landlord may request concerning the proposed subtenant or assignee, including recent financial statements certified as accurate and complete by a certified public accountant and by the president, managing partner or other appropriate officer of the proposed subtenant or assignee; (b) proof satisfactory to Landlord that the proposed subtenant or assignee will immediately occupy and thereafter use the entire Premises (or any sublet portion of the Premises) for the remainder of the Lease Term (or for the entire term of the sublease, if shorter) in compliance with the terms of this Lease; and (c) a copy of the proposed sublease or assignment or letter of intent. Tenant shall pay to Landlord, upon Landlord’s demand therefor, Landlord’s reasonable attorneys’ fees incurred in the review of such documentation and in documenting Landlord’s consent, plus an administrative fee of $500.00 as Landlord’s fee for processing such proposed assignment or sublease. Receipt of such fees shall not obligate Landlord to approve the proposed assignment or sublease.

4.16.3 In determining whether to grant or withhold consent to a proposed assignment or sublease, Landlord may consider, and weigh, any commercially reasonably factor it deems relevant, in its sole and absolute discretion.

4.16.4 Within fifteen (15) Business Days after Landlord’s receipt of all required information to be supplied by Tenant pursuant to this paragraph, Landlord shall notify Tenant of Landlord’s approval, disapproval or conditional approval of any proposed assignment or subletting or of Landlord’s election to recapture as described below. Landlord shall have no obligation to respond unless and until all required information has been submitted. In the event Landlord approves of any proposed assignment or subletting, Tenant and the proposed assignee or sublessee shall execute and deliver to Landlord an assignment (or subletting) and assumption agreement in form and content satisfactory to Landlord.

4.16.5 Any transfer, assignment or hypothecation of any of the stock or interest in Tenant, or the assets of Tenant, or any other transaction, merger, reorganization or event, however constituted which (a) results in fifty percent (50%), or more of such stock, interest or assets going into different ownership, or (b) is a subterfuge denying Landlord the benefits of this paragraph, shall be deemed to be an assignment within the meaning and provisions of this paragraph and shall be subject to the provisions of this paragraph.

4.16.6 If Landlord consents to any assignment or sublease and Tenant receives rent or any other consideration, either initially or over the term of the assignment or sublease, in excess of the Base Rent and Additional Rent (or, in the case of a sublease of a portion of the Premises, in excess of the Base Rent paid by Tenant on a square footage basis under this Lease) (such amount being referred to herein as the “Gross Profit”), Tenant shall pay to Landlord fifty percent (50%) of the Net Profit. As used herein, the “Net Profit” means the Gross Profit less the reasonable and customary marketing and transaction expenses incurred by Tenant in making such assignment or sublease including, without limitation, rent concessions such as free rent, marketing expenses, tenant improvements, reasonable and customary brokerage fees, and reasonable legal fees, provided that, for purposes of calculating the Net Profit, such expenses shall be amortized over the term of the applicable assignment or sublease.

4.16.7 Landlord shall have the right to recapture the Premises or the applicable portion thereof (a “Recapture”) by giving written notice of such Recapture to Tenant within fifteen (15) Business Days after receipt of Tenant’s written request for Landlord’s consent to such proposed assignment or subletting. Tenant shall have no right to retract its request for Landlord’s consent to assign or sublease once such request has been made. Such Recapture shall terminate this Lease as to the applicable space effective on the prospective effective date of assignment or subletting, which shall be the last day of a calendar month and shall not be earlier than forty-five (45) Business Days after receipt of Tenant’s request hereunder. If less than the entire Premises are recaptured, this Lease shall remain in full force and effect with respect to that remaining area not recaptured by Landlord. Tenant shall surrender that portion of the Premises recaptured by Landlord in accordance with the terms and conditions of this Lease. Notwithstanding the first sentence of this subparagraph, Landlord shall have no right to Recapture the Premises or applicable portion thereof if Tenant’s proposed assignment or sublet is to an Affiliate or a Permitted Transferee.

4.16.8 Notwithstanding anything to the contrary in this Lease, provided that all amounts due under this Lease have been paid in full and further provided that no Event of Default exists, upon not less than fifteen (15) Business Days advance written notice to Landlord but without Landlord’s consent, Tenant may assign this Lease or sublet all or any portion of the Premises to an Affiliate of the Tenant, provided (a) that Tenant has delivered to Landlord satisfactory evidence that the assignee or subtenant is an Affiliate of the Tenant, (b) Tenant reimburses Landlord on demand for all reasonable costs and expenses incurred by Landlord in determining compliance with the terms of this subparagraph 4.16.8, including reasonable attorneys’ fees, and (c) such entity remains an Affiliate of Tenant subsequent to the date of such assignment and for the remainder of the Lease Term. In all events, Tenant shall remain liable for its obligations under this Lease despite any such transfer.

If, at any time during the Lease Term, the Original Tenant (or a Permitted Transferee of all of

Tenant’s rights under this Lease) ceases to itself use and occupy the entire third floor of the Building and/or an Event of Default occurs, Landlord in its sole discretion may terminate Tenant’s right to maintain the Exterior Sign and may require Tenant to permanently remove the Exterior Sign.

(b) Prior to installation of the Exterior Sign, Tenant shall obtain any and all necessary permits and approvals required by applicable Governmental Requirements. At Tenant’s request and at Tenant’s sole cost and expense, Landlord shall cooperate with and assist Tenant in any reasonable way Tenant from time to time may request in connection with its efforts to obtain such permits and approvals, and Tenant shall reimburse Landlord on demand for any reasonable expenses incurred by Landlord in connection therewith. Thereafter, Tenant shall at all times maintain all necessary permits and approvals required by the applicable Governmental Requirements in effect from time to time.

If Tenant fails to perform such work or if Landlord in its sole discretion elects to perform such work on Tenant’s behalf, Landlord may cause the same to be performed, and the cost thereof shall be Additional Rent immediately due and payable upon rendition of a ▇▇▇▇ therefor.

4.23.3 Landlord reserves the right to require Tenant to relocate its Exterior Sign to another location on the exterior of the Building upon sixty (60) days advance written notice at Landlord’s sole cost and expense.

Notwithstanding the foregoing, the holder or beneficiary of such mortgage, deed of trust, ground lease, vendor’s lien or similar instrument shall have the right to subordinate or cause to be subordinated any such mortgage, deed of trust, ground lease, vendor’s lien or similar instrument to this Lease or to execute a non-disturbance agreement in favor of Tenant on the standard form utilized by such lender or ground lessor. At the request of Landlord, the holder of such mortgage or deed of trust or any ground lessor, Tenant shall execute, acknowledge and deliver promptly in recordable form any instrument or subordination agreement that Landlord or such holder may request. Tenant further covenants and agrees that if the lender or ground lessor acquires the Premises as a purchaser at any foreclosure sale or otherwise, Tenant shall recognize and attorn to such party as landlord under this Lease, and shall make all payments required hereunder to such new landlord without deduction or set-off and, upon the request of such purchaser or other successor, execute, deliver and acknowledge documents confirming such attornment. Tenant waives the provisions of any law or regulation, now or hereafter in effect, which may give or purport to give Tenant any right to terminate or otherwise adversely affect this Lease or the obligations of Tenant hereunder in the event that any such foreclosure or termination or other proceeding is prosecuted or completed.

4.24.2 If at any time during the Lease Term the Building is encumbered by a mortgage, then upon Tenant’s written request, Landlord shall use commercially reasonable efforts to obtain for Tenant, at no cost to Landlord, a subordination, non-disturbance and attornment agreement from the holder of such mortgage, in the standard form customarily employed by such holder, provided that Landlord shall have no liability to Tenant, and the effectiveness of this Lease and the subordination of this Lease to any mortgage shall not be affected, in the event that it is unable to obtain any such agreement. Tenant shall reimburse Landlord, within ten (10) days after demand therefor, for Landlord’s out-of-pocket costs, including fees charged by the holder(s) of any mortgage(s) and its or their counsel and other reasonable attorney’s fees and disbursements, incurred in connection with such efforts.

Notwithstanding anything contained in this Lease to the contrary, Tenant confirms that the covenants of Landlord are made and intended, not as personal covenants of the Landlord’s authorized representative or for the purpose of binding such authorized representative personally, but solely in the exercise of the representative powers conferred upon such authorized representative by their principal. Liability with respect to the entry and performance of this Lease by or on behalf of Landlord, however it may arise, shall be asserted and enforced only against Landlord’s estate and equity interest in the Building. Neither Landlord nor any of Landlord’s Agents shall have any personal liability in the event of any claim against Landlord arising out of or in connection with this Lease, the relationship of Landlord and Tenant or Tenant’s use of the Premises. Further, in no event whatsoever shall any Landlord’s Agent have any liability or responsibility whatsoever arising out of or in connection with this Lease, the relationship of Landlord and Tenant or Tenant’s use of the Premises.

At Tenant’s expense and subject to availability, Landlord shall make available Tenant’s Pro Rata Share of any conduit space in the vertical risers of the Building which the Landlord from time to time makes available to tenants of the Building for purposes of running wiring and cabling in order to connect Tenant’s Rooftop Equipment to the Premises.

Tenant, for the purpose of this paragraph and its right to rooftop access hereunder, accepts the rooftop in its “AS IS” condition.

4.31.2 Prior to installation, Tenant will obtain any and all necessary licenses, approvals, permits, etc., necessary for the installation, maintenance and use of the Rooftop Equipment.

The installation of the Rooftop Equipment shall be performed at Tenant’s expense by Landlord or by Tenant at Landlord’s election and by contractors previously approved by Landlord. In no event shall the Landlord’s approval of Tenant’s plans and specifications be deemed a representation that Tenant’s Rooftop Equipment or plans and specifications comply with Governmental Requirements and/or the terms of this Lease. Without limiting the foregoing, Landlord’s approval of Tenant’s plans and specifications shall not be deemed a representation that use of Tenant’s Rooftop Equipment will not cause interference with other systems in the Building. Landlord reserves the right to require Tenant to relocate its Rooftop Equipment to another location on the roof of the Building upon fifteen (15) days advance written notice.

4.31.4 Tenant, through its designated and approved employees and contractors, shall be solely responsible for the maintenance and care of the Rooftop Equipment and associated wiring and cabling and shall maintain the same in a clean, sanitary and safe condition and in good repair and free of any defects at all times during this Lease.

The Tenant will, at its sole cost and expense, promptly comply or ensure that the roof installations comply with all Governmental Requirements or requirements of any board of fire insurance underwriters or other similar bodies now or hereafter constituted relating to or affecting Tenant’s roof use. If the rate of any insurance carried by Landlord is increased as a result of Tenant’s roof use, then Tenant from time to time will pay to Landlord within fifteen (15) days after demand by Landlord a sum equal to such increased cost.

4.31.7 Without limiting any other indemnification contained herein, Tenant shall indemnify and hold Landlord harmless from and against any and all Claims arising out of (a) any violations of

If Tenant fails to remove any such Rooftop Equipment and all associated wiring and cabling connecting the Rooftop Equipment to Tenant’s Premises prior to the expiration or earlier termination of the Lease, Landlord may do so and Tenant shall pay the entire cost thereof to Landlord. In the event that Landlord performs any such installation, maintenance, removal or repair work on behalf of Tenant, Tenant shall reimburse Landlord within ten (10) days after Tenant’s receipt of Landlord’s written demand therefor, which obligation shall survive expiration or earlier termination of the Lease.

At Tenant’s expense, Landlord shall make available Tenant’s Pro Rata Share of any conduit space in the vertical risers of the Building which the Landlord from time to time makes available to tenants of the Building for purposes of running wiring and cabling in order to connect Tenant’s Generator to the Premises. As used herein, “Tenant’s Generator Area” shall mean and refer to an area approved by Landlord on either the roof of the Building or in the loading dock area of the Building. No additional rental shall be payable in respect of the installation and use of the Generator and associated wiring and cabling. Landlord shall not make any representations or promises pertaining to the suitability of the Tenant’s Generator Area for Tenant’s use. Tenant, for the purpose of this paragraph and its right to access the Tenant’s Generator Area hereunder, shall accept the Tenant’s Generator Area in its “AS IS” condition.

4.32.2 Prior to installation, Tenant will obtain any and all necessary licenses, approvals, permits, etc., necessary for the installation, maintenance and use of the Generator.

Tenant shall reimburse Landlord, within ten (10) Business Days after receipt of an invoice, for all reasonable out-of-pocket costs and expenses incurred by Landlord related to its review of Tenant’s plans and specifications, including the fees and expenses of Landlord’s consultant (regardless of whether Landlord approves Tenant’s plans and specifications) and Tenant’s installation. The installation of the Generator shall be performed at Tenant’s expense by Landlord or by Tenant at Landlord’s election and by contractors previously approved by Landlord. In no event shall the Landlord’s approval of Tenant’s plans and specifications be deemed a representation that Tenant’s Generator or plans and specifications comply with Governmental Requirements and/or the terms of this Lease. Without limiting the foregoing, Landlord’s approval of Tenant’s plans and specifications shall not be deemed a representation that use of Tenant’s Generator will not cause interference with other systems in the Building. Landlord reserves the right to require Tenant to relocate its Generator to another location upon fifteen (15) days advance written notice.

4.32.4 Tenant, through its designated and approved employees and contractors, shall be solely responsible for the maintenance and care of the Generator and associated wiring and cabling and shall maintain the same in a clean, sanitary and safe condition and in good repair and free of any defects at all times during this Lease. Tenant, at its sole expense and risk, shall ensure that a physical inspection of the Generator occurs at intervals of no more than three (3) months and that this inspection include a survey of structural integrity and a review and correction of any loose bolts, fittings or other appurtenances. Tenant shall provide a written certification of such inspections to Landlord not more than ten (10) days following each such inspection. In the absence of such a certification, Landlord shall have the right (but not the obligation) to conduct or arrange for such an inspection and corrective action and to charge Tenant for such costs.

4.32.5 Tenant covenants upon installation that the Generator will not interfere with other equipment associated with the operation of the Building or any other building of the Park. Upon receipt of notice from Landlord, Tenant shall eliminate any such interference.

4.32.6 Tenant’s Generator Rights shall be exercised in such manner as: (1) will not create any hazardous condition or interfere with or impair the operation of the heating, ventilation, air conditioning, plumbing, electrical, fire protection, life safety, public utilities or other systems or facilities of the Building, (2) will not directly or indirectly interfere with, delay, restrict or impose any expense, work or obligation upon Landlord in the use or operation of the Building, and (3) shall not in any way conflict with any Governmental Requirement now in force or which may hereafter be enacted. The Tenant will, at its sole cost and expense, promptly comply or ensure that the Building complies with all Governmental Requirements or requirements of any board of fire insurance underwriters or other similar bodies now or hereafter constituted relating to or affecting Tenant’s installation, maintenance, use, and removal of the Generator. If the rate of any insurance carried by Landlord is increased as a result of Tenant’s installation, maintenance, use, and removal of the Generator, then Tenant from time to time will pay to Landlord within ten (10) Business Days after demand by Landlord a sum equal to such increased cost.

4.32.7 Without limiting any other indemnification contained herein, Tenant shall indemnify and hold Landlord harmless from and against any and all Claims arising out of (a) any violations of Governmental Requirements relating to Tenant’s Generator and related facilities, and (b) the installation, maintenance use and/or removal of such Generator and related facilities.

4.32.8 Tenant’s Generator Rights shall not be transferable to any party other than a Permitted Transferee and shall be used solely in the ordinary course of Tenant’s business operations.

4.32.9 Unless Landlord agrees in writing to permit Tenant to leave the Generator in place, upon the expiration or earlier termination of the Lease Term, Tenant shall remove its Generator and all associated wiring and cabling connecting the Generator to Tenant’s Premises and repair any and all damage caused to the Tenant’s Generator Area or any other part of the Building and/or Land by the installation or removal of said Generator. If Tenant fails to remove any such Generator and all associated

wiring and cabling connecting the Generator to Tenant’s Premises prior to the expiration or earlier termination of the Lease, Landlord may do so and Tenant shall pay the entire cost thereof to Landlord within ten (10) days after Tenant’s receipt of Landlord’s written demand therefor, which obligation shall survive expiration or earlier termination of the Lease.

4.32.10 Upon reasonable notice, the Landlord shall permit Tenant to access the Tenant’s Generator Area of the Building at reasonable times for purposes of Tenant’s exercise of its rights under this Paragraph 4.32.

SECTION 5: DEFAULT AND REMEDIES

5.1 Events of Default.

5.1.1 The occurrence of any one or more of the following events shall constitute a material default and breach of this Lease by Tenant (“Event of Default”):

(a) vacation or abandonment of all or any portion of the Premises;

(b) failure by Tenant to make any payment of Base Rent, Additional Rent or any other sum payable by Tenant under this Lease within five (5) Business Days after written notice from Landlord that such payment was not paid when due, provided, however, Landlord need not give any such notice more than once in any twelve (12) month period, and any further failure by Tenant within any such twelve (12) month period to make any payment of Base Rent, Additional Rent or any other sum payable by Tenant under this Lease within five (5) Business Days after its due date shall constitute an immediate Event of Default without any notice from Landlord;

(c) failure by Tenant to observe or perform any covenant or condition of this Lease, other than the making of payments, where such failure shall continue for a period of fifteen (15) Business Days after written notice from Landlord, provided, however, if cure is not reasonably capable of being completed within such time period, Tenant shall have such additional reasonable time (not to exceed an additional thirty (30) calendar days) as is required to cure such default as long as Tenant promptly commences such cure within said fifteen (15) Business Day period and thereafter diligently pursues such cure to completion;

(d) the failure of Tenant to surrender possession of the Premises at the expiration or earlier termination of this Lease in the condition required by this Lease;

(e) (1) the making by Tenant of any general assignment or general arrangement for the benefit of creditors; (2) the filing by or against Tenant of a petition in bankruptcy, including reorganization or arrangement, unless, in the case of a petition filed against Tenant, unless the same is dismissed within twenty (20) Business Days; (3) the appointment of a trustee or receiver to take possession of substantially all of Tenant’s assets located in the Premises or of Tenant’s interest in this Lease; (4) any execution, levy, attachment or other process of law against any property of Tenant or Tenant’s interest in this Lease, unless the same is dismissed within twenty (20) Business Days; (5) adjudication that Tenant is bankrupt; (6) the making by Tenant of a transfer in fraud of creditors; or (7) the failure of Tenant to generally pay its debts as they become due; or

(f) any material information furnished by or on behalf of Tenant to Landlord in connection with the entry of this Lease is determined to have been materially false, misleading or incomplete when made.

(g) a failure of the Tenant to deliver the Letter of Credit within the time period specified in the paragraph captioned “Lease Security”.

5.1.2 Tenant shall notify Landlord promptly of any Event of Default or any facts, conditions or

events which, with the giving of notice or passage of time or both, would constitute an Event of Default.

5.1.3 If a petition in bankruptcy is filed by or against Tenant, and if this Lease is treated as an “unexpired lease” under applicable bankruptcy law in such proceeding, then Tenant agrees that Tenant shall not attempt nor cause any trustee to attempt to extend the applicable time period within which this Lease must be assumed or rejected.

5.2 Remedies. If any Event of Default occurs, Landlord may at any time after such occurrence, with or without notice or demand except as stated in this paragraph, and without limiting Landlord in the exercise of any right or remedy at law which Landlord may have by reason of such Event of Default, exercise the rights and remedies, either singularly or in combination, as are specified or described in the subparagraphs of this paragraph.

5.2.1 Landlord may terminate this Lease and all rights of Tenant under this Lease either immediately or at some later date by giving Tenant written notice that this Lease is terminated. If Landlord so terminates this Lease, then Landlord may recover from Tenant the sum of:

(a) the unpaid Base Rent, Additional Rent and all other sums payable under this Lease which have been earned at the time of termination;

(b) interest at the Default Rate on the unpaid Base Rent, Additional Rent and all other sums payable under this Lease which have been earned at the time of termination; plus

(c) the amount by which the unpaid Base Rent, Additional Rent and all other sums payable under this Lease which would have been earned after termination until the time of award exceeds the amount of such rental loss, if any, as Tenant affirmatively proves could have been reasonably avoided and interest on such excess at the Default Rate; plus

(d) the amount by which the aggregate of the unpaid Base Rent, Additional Rent and all other sums payable under this Lease for the balance of the Lease Term after the time of award exceeds the amount of such rental loss, if any, as Tenant affirmatively proves could be reasonably avoided, with such difference being discounted to present value at the Prime Rate at the time of award; plus

(e) any other amount necessary to compensate Landlord for the detriment proximately caused by Tenant’s failure to perform Tenant’s obligations under this Lease or which, in the ordinary course of things, would be likely to result from such failure, including, leasing commissions, tenant improvement costs, renovation costs and advertising costs; plus

(f) all such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable law.

5.2.2 Landlord shall also have the right, with or without terminating this Lease, to re-enter the Premises and remove all persons and property from the Premises. Landlord may cause property so removed from the Premises to be stored in a public warehouse or elsewhere at the expense and for the account of Tenant.

5.2.3 Landlord shall also have the right, without terminating this Lease, to accelerate and recover from Tenant the sum of all unpaid Base Rent, Additional Rent and all other sums payable under the then remaining term of the Lease, discounting such amount to present value at the Prime Rate.

5.2.4 If Tenant vacates, abandons or surrenders the Premises without Landlord’s consent, or if Landlord re-enters the Premises as provided in subparagraph 5.2.2 or takes possession of the Premises pursuant to legal proceedings or through any notice procedure provided by law, then, if Landlord does not elect to terminate this Lease, Landlord may, from time to time, without terminating this Lease, either (a) recover all Base Rent, Additional Rent and all other sums payable under this Lease as they become due

or (b) relet the Premises or any part of the Premises on behalf of Tenant for such term or terms, at such rent or rents and pursuant to such other provisions as Landlord, in its sole discretion, may deem advisable, all with the right, at Tenant’s cost, to make alterations and repairs to the Premises and recover any deficiency from Tenant as set forth in subparagraph 5.2.6.

5.2.5 None of the following remedial actions, singly or in combination, shall be construed as an election by Landlord to terminate this Lease unless Landlord has in fact given Tenant written notice that this Lease is terminated: (a) an act by Landlord to maintain or preserve the Premises; (b) any efforts by Landlord to relet the Premises; (c) any repairs or alterations made by Landlord to the Premises; (d) re-entry, repossession or reletting of the Premises by Landlord pursuant to this paragraph; or (e) the appointment of a receiver, upon the initiative of Landlord, to protect Landlord’s interest under this Lease. If Landlord takes any of the foregoing remedial action without terminating this Lease, Landlord may nevertheless at any time after taking any such remedial action terminate this Lease by written notice to Tenant.

5.2.6 If Landlord relets the Premises, Landlord shall apply the revenue from such reletting as follows: first, to the payment of any indebtedness of Tenant to Landlord other than Base Rent, Additional Rent or any other sums payable by Tenant under this Lease; second, to the payment of any cost of reletting (including finders’ fees and leasing commissions); third, to the payment of the cost of any alterations, improvements, maintenance and repairs to the Premises; and fourth, to the payment of Base Rent, Additional Rent and other sums due and payable and unpaid under this Lease. Landlord shall hold and apply the residue, if any, to payment of future Base Rent, Additional Rent and other sums payable under this Lease as the same become due, and shall deliver the eventual balance, if any, to Tenant. Should revenue from letting during any month, after application pursuant to the foregoing provisions, be less than the sum of the Base Rent, Additional Rent and other sums payable under this Lease and Landlord’s expenditures for the Premises during such month, Tenant shall be obligated to pay such deficiency to Landlord as and when such deficiency arises.

5.2.7 Pursuit of any of the foregoing remedies shall not preclude pursuit of any of the other remedies provided in this Lease or by law (all such remedies being cumulative), nor shall pursuit of any remedy provided in this Lease constitute a forfeiture or waiver of any Base Rent, Additional Rent or other sum payable under this Lease or of any damages accruing to Landlord by reason of the violation of any of the covenants or conditions contained in this Lease.

5.3 Right to Perform. If Tenant shall fail to pay any sum of money, other than Base Rent or Additional Rent, required to be paid by it under this Lease or shall fail to perform any other act on its part to be performed under this Lease, and such failure shall continue for ten (10) Business Days after notice of such failure by Landlord, or such shorter time in the event of an emergency and/or if necessary to prevent damage to persons or property as determined by Landlord acting in good faith, Landlord may, but shall not be obligated to, and without waiving or releasing Tenant from any obligations of Tenant, make such payment or perform such other act on Tenant’s part to be made or performed as provided in this Lease. Landlord shall have (in addition to any other right or remedy of Landlord) the same rights and remedies in the event of the nonpayment of sums due under this paragraph as in the case of default by Tenant in the payment of Base Rent.

5.4 Landlord’s Default. Landlord shall not be in default under this Lease unless Landlord fails to perform obligations required of Landlord within twenty (20) Business Days after written notice is delivered by Tenant to Landlord and to the holder of any mortgages or deeds of trust (collectively, “Lender”) covering the Premises whose name and address shall have theretofore been furnished to Tenant in writing, specifying the obligation which Landlord has failed to perform; provided, however, that if the nature of Landlord’s obligation is such that more than twenty (20) Business Days are required for performance, then Landlord shall not be in default if Landlord or Lender commences performance within such twenty (20) Business Day period and thereafter diligently prosecutes the same to completion. All obligations of Landlord hereunder shall be construed as covenants, not conditions. In the event of any default, breach or violation of Tenant’s rights under this Lease by Landlord, Tenant’s exclusive remedy shall be either an action for specific performance or an action for actual damages. Tenant hereby waives

the benefit of any laws granting it the right to perform Landlord’s obligation, a lien upon the property of Landlord and/or upon Rent due Landlord, or the right to terminate this Lease or withhold Rent on account of any Landlord default.

SECTION 6: MISCELLANEOUS PROVISIONS

6.1 Notices. Any notice, request, approval, consent or written communication required or permitted to be delivered under this Lease shall be: (a) in writing; (b) transmitted by personal delivery, express or courier service, United States Postal Service in the manner described below, or electronic means of transmitting written material; and (c) deemed to be delivered on the earlier of the date received or four (4) Business Days after having been deposited in the United States Postal Service, postage prepaid. Such writings shall be addressed to Landlord or Tenant, as the case may be, at the respective designated addresses set forth opposite their signatures, or at such other address(es) as they may, after the execution date of this Lease, specify by written notice delivered in accordance with this paragraph, with copies to the persons at the addresses, if any, designated opposite each party’s signature. Those notices which contain a notice of breach or default or a demand for performance may be sent by any of the methods described in clause (b) above, but if transmitted by personal delivery or electronic means, shall also be sent concurrently by certified or registered mail, return receipt requested.

6.2 Attorney’s Fees and Expenses. In the event either party requires the services of an attorney in connection with enforcing the terms of this Lease, or in the event suit is brought for the recovery of Base Rent, Additional Rent or any other sums payable under this Lease or for the breach of any covenant or condition of this Lease, or for the restitution of the Premises to Landlord or the eviction of Tenant during the Lease Term or after the expiration or earlier termination of this Lease, the non-breaching party shall be entitled to a reasonable sum for attorney’s and paralegal’s fees, expenses and court costs, including those relating to any appeal.

6.3 No Accord and Satisfaction. No payment by Tenant or receipt by Landlord of an amount less than the Base Rent or Additional Rent or any other sum due and payable under this Lease shall be deemed to be other than a payment on account of the Base Rent, Additional Rent or other such sum, nor shall any endorsement or statement on any check or any letter accompanying any check or payment be deemed an accord and satisfaction, nor preclude Landlord’s right to recover the balance of any amount payable or Landlord’s right to pursue any other remedy provided in this Lease or at law.

6.4 Successors; Joint and Several Liability. Except as provided in the paragraph captioned “Limitation on Recourse” and subject to the paragraph captioned “Assignment and Subletting by Landlord”, all of the covenants and conditions contained in this Lease shall apply to and be binding upon Landlord and Tenant and their respective heirs, executors, administrators, successors and assigns. In the event that more than one person, partnership, company, corporation or other entity is included in the term “Tenant”, then each such person, partnership, company, corporation or other entity shall be jointly and severally liable for all obligations of Tenant under this Lease.

6.5 Choice of Law. This Lease shall be construed and governed by the laws of the state in which the Land is located. Tenant consents to Landlord’s choice of venue for any legal proceeding brought by Landlord or Tenant to enforce the terms of this Lease.

6.6 No Waiver of Remedies. The waiver by Landlord of any covenant or condition contained in this Lease shall not be deemed to be a waiver of any subsequent breach of such covenant or condition nor shall any custom or practice which may develop between the parties in the administration of this Lease be construed to waive or lessen the rights of Landlord to insist on the strict performance by Tenant of all of the covenants and conditions of this Lease. No act or thing done by Landlord or Landlord’s Agents during the Lease Term shall be deemed an acceptance or a surrender of the Premises, and no agreement to accept a surrender of the Premises shall be valid unless made in writing and signed by Landlord. The mention in this Lease of any particular remedy shall not preclude Landlord from any other remedy it might have, either under this Lease or at law, nor shall the waiver of or redress for any violation of any covenant or condition in this Lease or in any of the rules or regulations attached to this Lease or later adopted by

Landlord, prevent a subsequent act, which would have originally constituted a violation, from having all the force and effect of an original violation. The receipt by Landlord of Base Rent, Additional Rent or any other sum payable under this Lease with knowledge of a breach of any covenant or condition in this Lease shall not be deemed a waiver of such breach. The failure of Landlord to enforce any of the rules and regulations attached to this Lease or later adopted, against Tenant or any other tenant in the Building, shall not be deemed a waiver. Any waiver by Landlord must be in writing and signed by Landlord to be effective.

6.7 Offer to Lease. The submission of this Lease in a draft form to Tenant or its broker or other agent does not constitute an offer to Tenant to lease the Premises. This Lease shall have no force or effect until: (a) it is executed and delivered by Tenant to Landlord; and (b) it is executed and delivered by Landlord to Tenant.

6.8 Force Majeure. Except as to the obligation of Tenant to pay Base Rent, Additional Rent or other charges hereunder, in the event that Landlord or Tenant shall be delayed, hindered in or prevented from the performance of any act or obligation required under this Lease by reason of acts of God, strikes, lockouts, labor troubles or disputes, inability to procure or shortage of materials or labor, failure of power or utilities, delay in transportation, fire, vandalism, accident, flood, severe weather, other casualty, Governmental Requirements (including mandated changes in the Plans and Specifications or the Tenant Improvements resulting from changes in pertinent Governmental Requirements or interpretations thereof), riot, insurrection, civil commotion, sabotage, explosion, war, natural or local emergency, acts or omissions of others, including Tenant or Landlord (as applicable), or other reasons of a similar or dissimilar nature not solely the fault of, or under the exclusive control of, the non-performing party, then performance of such act or obligation shall be excused for the period of the delay and the period for the performance of any such act or obligation shall be extended for the period equivalent to the period of such delay. In no event shall the payment of money be excused by reason of Force Majeure.

6.9 Landlord’s Consent. Unless otherwise provided in this Lease, whenever Landlord’s consent, approval or other action is required under the terms of this Lease, such consent, approval or action shall be subject to Landlord’s judgment or discretion exercised in good faith and shall be delivered in writing.

6.10 Severability; Captions. If any clause or provision of this Lease is determined to be illegal, invalid, or unenforceable under present or future laws, the remainder of this Lease shall not be affected by such determination, and in lieu of each clause or provision that is determined to be illegal, invalid or unenforceable, there be added as a part of this Lease a clause or provision as similar in terms to such illegal, invalid or unenforceable clause or provision as may be possible and be legal, valid and enforceable. Headings or captions in this Lease are added as a matter of convenience only and in no way define, limit or otherwise affect the construction or interpretation of this Lease.

6.11 Interpretation. Whenever a provision of this Lease uses the term (a) “include” or “including”, that term shall not be limiting but shall be construed as illustrative, (b) “covenant”, that term shall include any covenant, agreement, term or provision, (c) “at law”, that term shall mean as specified in any applicable statute, ordinance or regulation having the force of law or as determined at law or in equity, or both, and (d) “day”, that uncapitalized word shall mean a calendar day. This Lease shall be given a fair and reasonable interpretation of the words contained in it without any weight being given to whether a provision was drafted by one party or its counsel.

6.12 Incorporation of Prior Agreement; Amendments. This Lease contains all of the agreements of the parties to this Lease with respect to any matter covered or mentioned in this Lease, and no prior agreement or understanding pertaining to any such matter shall be effective for any purpose. No provision of this Lease may be amended or added to except by an agreement in writing signed by the parties to this Lease or their respective successors in interest.

6.13 Authority. If Tenant is a partnership, company, corporation or other entity, each individual executing this Lease on behalf of Tenant represents and warrants to Landlord that he or she is duly authorized to so execute and deliver this Lease and that all partnership, company, corporation or other

entity actions and consents required for execution of this Lease have been given, granted or obtained. If Tenant is a partnership, company, corporation or other business organization, it shall, within ten (10) Business Days after demand by Landlord, deliver to Landlord satisfactory evidence of the due authorization of this Lease and the authority of the person executing this Lease on its behalf.

6.14 Time of Essence. Time is of the essence with respect to the performance of every covenant and condition of this Lease.

6.15 Survival of Obligations. Notwithstanding anything contained in this Lease to the contrary or the expiration or earlier termination of this Lease, any and all obligations of either party accruing prior to the expiration or termination of this Lease shall survive the expiration or earlier termination of this Lease, and either party shall promptly perform all such obligations whether or not this Lease has expired or terminated. Such obligations shall include any and all indemnity obligations set forth in this Lease.

6.16 Consent to Service. Tenant irrevocably consents to the service of process of any action or proceeding at the address of the Premises. Nothing in this paragraph shall affect the right to serve process in any other manner permitted by law.

6.17 Landlord’s Authorized Agents. Notwithstanding anything contained in the Lease to the contrary, including without limitation, the definition of Landlord’s Agents, only officers of Landlord, are authorized to amend, renew or terminate this Lease, or to compromise any of Landlord’s claims under this Lease or to bind Landlord in any manner. Without limiting the effect of the previous sentence, no property manager or broker shall be considered an authorized agent of Landlord to amend, renew or terminate this Lease, to compromise any of Landlord’s claims under this Lease or to bind Landlord in any manner.

6.18 Waiver of Jury Trial. Landlord and Tenant irrevocably waive the respective rights to trial by jury in any action, proceeding or counterclaim brought by either against the other (whether in contract or tort) on any matter arising out of or relating in any way to this Lease, the relationship of Landlord and Tenant or Tenant’s use or occupancy of the Premises.

6.19 Specially Designated National or Blocked Person. Tenant hereby represents its compliance with all applicable anti-money laundering laws, including, without limitation, the USA Patriot Act, and the laws administered by the United States Treasury Department’s Office of Foreign Assets Control, including, without limitation, Executive Order 13224. Tenant further represents (i) that it is not, and it is not owned or controlled directly or indirectly by any person or entity, on the Specially Designated Nationals (SDN) List published by the United States Treasury Department’s Office of Foreign Assets Control and (ii) that it is not a person otherwise identified by government or legal authority as a person with whom a U.S. Person is prohibited from transacting business. As of the date hereof, a list of such designations and the text of Executive Order 13224 are published under the internet address ▇▇▇.▇▇▇▇▇▇▇.▇▇▇/▇▇▇▇▇▇▇/▇▇▇▇▇▇▇▇▇▇▇/▇▇▇▇. Tenant covenants and agrees to deliver to Landlord any certification or other evidence requested from time to time by Landlord in its reasonable discretion, confirming Tenant’s compliance with this paragraph 6.19. Notwithstanding the foregoing, Landlord shall not request such certification or evidence more than twice in any twelve (12) month period unless an Event of Default exists or (a) such request is made in connection with any governmental inquiry of Landlord, (b) such certification or evidence is necessary for Landlord to comply with any law or regulation and/or any insurance regulation or requirement.

6.20 Right of First Refusal.

6.20.1 Pursuant to the terms, conditions and limitations set forth in this paragraph 6.20, Tenant shall have a right of first refusal (the “Right to First Refusal”) with respect to the second (2nd) floor of the Building (the “Second Floor Space”).

6.20.2 When Landlord receives an offer to lease any Second Floor Space from any third party which Landlord desires to accept (expressly including such offers which Landlord has solicited and which

a third party has indicated it will accept) (each, an “Offer”), Landlord shall first present such Offer, in writing, to Tenant, and Tenant shall thereafter have five (5) Business Days in which to accept that Offer by delivery of written notice to Landlord. If Tenant fails to deliver to Landlord written acceptance of any Offer within the five (5) Business Day period set forth herein, then Tenant’s rights with respect to such Offer and the space referenced therein shall be void, and Landlord shall be free to lease the space that was the subject of such Offer to any third party.

6.20.3 In the event that the particular Offer from any third party includes space in the Building in addition to the applicable Second Floor Space, Landlord shall present such additional space to Tenant as part of the Offer (with any space presented to Tenant under this paragraph 6.20, whether Second Floor Space or other additional space, being “ROFR Space”). The Right of First Refusal shall apply only to the entire portion of the ROFR Space that is the subject of any Offer that is presented to Tenant, and may not be exercised by Tenant with respect to only a portion thereof (so that if the Offer includes Second Floor Space and other additional space, Tenant may only accept the entirety of the Second Floor Space and such additional space).

6.20.4 If Tenant declines to exercise such Right of First Refusal with respect to any particular ROFR Space, and an offer from a different third party prospect is thereafter offered to Landlord with respect to the same ROFR Space that Landlord desires to accept, Landlord shall have no obligation to re-offer such ROFR Space to Tenant on the terms offered by such different prospect (nor shall have Landlord have any similar obligation with respect to any additional offers from additional prospects received by Landlord with respect to the particular ROFR Space). In addition, the Right of First Refusal and Tenant’s rights under this paragraph 6.20 shall automatically terminate once Tenant has been presented with an Offer (or, if applicable, Offers) applicable to at least twenty thousand (20,000) rentable square feet of Second Floor Space in the aggregate.

6.20.5 If Tenant validly exercises the Right of First Refusal provided in this Lease, the parties shall execute an addendum to the Lease adding the ROFR Space to the Premises on the terms set forth in the Offer. If the term of the ROFR Space included in the Offer extends further than the Lease Term with respect to the then Premises, Tenant’s leasing of the ROFR Space shall be for the duration included in the Offer (on the economic terms applicable thereto set forth in the Offer). Except as otherwise set forth in the Offer, the terms applicable to the then existing Premises shall apply to the ROFR Space (provided that Tenant shall not have any right to the Extension Option with respect to the ROFR Space, or any other extension right, unless set forth in the Offer). Provided, however, an otherwise valid exercise of the Right of First Refusal contained in this Lease shall be fully effective, whether or not such confirmatory documentation is executed, and Tenant’s tenancy of such ROFR Space shall be subject to all the rights and obligations of the parties under this Lease.

6.20.6 Notwithstanding anything to the contrary in this Lease, Landlord shall have no obligations, and Tenant shall have no rights, under this paragraph 6.20 so long as an Event of Default has occurred and is continuing.

Tenant shall endeavor to design the

Expansion Improvements consistent with the Landlord’s sustainability practices and certain Green Agency Ratings (as determined by Landlord), specifically the SMACNA “IAQ Guidelines for Occupied Buildings under Construction” 1995, Chapter 3. Tenant further agrees to engage a third party LEED or Green Globe Accredited Professional or similarly qualified professional with respect to the design and construction of the Expansion Improvements. Tenant also shall endeavor to construct the Expansion Premises and the Initial Premises to certified LEED CI standards, and Tenant shall have the right to request descriptions of recent commissioning and energy audits that the Landlord has undertaken to understand and retrofit building systems to the green/sustainable level referenced above.

If Landlord shall disapprove of any portion of the Expansion Space Plan, Landlord shall advise Tenant of the reasons therefor and shall notify Tenant of the revisions to the Expansion Space Plan that are reasonably required by Landlord for the purpose of obtaining approval.

If Landlord shall disapprove of any portion of the Expansion Plans and Specifications, Landlord shall advise Tenant within such five (5) Business Day period of the reasons therefor and shall notify Tenant in writing of the revisions to the Expansion Plans and Specifications that are reasonably required by Landlord for the purpose of obtaining approval.

The Expansion Commencement Date shall be the date set forth in the definition of that term in Section 2 hereof. Tenant

acknowledges that upon the substantial completion of Landlord’s Expansion Work the Expansion Premises shall be delivered AS IS and that no representations as to the condition of the Expansion Premises have been made by Landlord, provided that all base building systems shall be in good working order at the time of delivery of the Expansion Premises to Tenant. The taking of possession by Tenant shall establish that the Expansion Premises are in good and satisfactory condition when possession was so taken and the Expansion Commencement Date shall occur as provided in the definition of that term. In no event shall Tenant’s refusal or failure to take possession of the Expansion Premises delay or postpone the occurrence of the Expansion Commencement Date unless such refusal or failure is a result of Landlord’s failure to provide the Expansion Premises in good and satisfactory condition. Tenant’s possession of the Expansion Premises prior to the Expansion Commencement Date shall be solely for purposes of moving in furniture and equipment, preparing cabling and wiring and performing the Expansion Improvements as provided above and shall be subject to all of the terms and conditions of this Lease, except that Tenant shall not be required to pay Base Rent for the Expansion Premises with respect to the period of time prior to the Expansion Commencement Date during which Tenant performs such work. Tenant, however, shall be liable for payment of any above standard services (such as after hours HVAC service) that are provided to Tenant during the period of Tenant’s possession of the Expansion Premises prior to the Expansion Commencement Date).

8. Tenant’s Contribution to Expansion Tenant Improvement Costs.

(a) Upon receipt of possession of the Expansion Premises, the Tenant shall prepare the Expansion Premises and the Initial Premises for Tenant’s occupancy and complete the Expansion Improvements in accordance with the Expansion Plans and Specifications in all material respects and at the Tenant’s sole cost and expense (all such costs and expenses, including all hard and soft costs such as and without limitation, all labor and materials, architectural, engineering, permitting, and space planning fees are hereinafter collectively referred to as the “Expansion Tenant Improvement Costs”). Tenant shall make no material changes to the Expansion Plans and Specifications or the work reflected in the Expansion Plans and Specifications without the written consent of the Landlord, which consent shall not be unreasonably withheld provided such changes do not affect any structural elements of the Building or Building systems. In no event shall Tenant make any changes to the Expansion Plans and Specifications or the work reflected in the Expansion Plans and Specifications without the consent of the Landlord if such changes affect any structural elements of the Building or Building systems and/or the location of any door or wall. Tenant’s completion of the Expansion Improvements shall be performed by Tenant’s contractors, who shall (i) be selected by Tenant and approved by Landlord (such approval not to be unreasonably withheld or delayed), and (ii) work under the direction of Tenant or, if directed in writing by Tenant, Tenant’s qualified representative. Landlord shall have the right, at Landlord’s sole cost and expense, to have its representative at the Expansion Premises and the Initial Premises at all times during the construction of the Expansion Improvements to review and monitor the performance of same, and Tenant shall pay Landlord a construction monitoring fee equal to one percent (1%) of the Expansion Tenant Improvement Costs (the “Expansion Construction Monitoring Fee”). The Expansion Improvements shall be performed by contractors approved by Landlord and employed by Tenant under one or more construction contracts that require the prime contractor and the respective subcontractors of any tier: (x) be parties to, and bound by, a collective bargaining agreement with a labor organization affiliated with the Building and Construction Trades Council of the AFL-CIO and (y) employ only members of such organization to perform work within their respective jurisdictions). However, at Landlord’s sole option, in clause (x) of the immediately preceding sentence of this paragraph, the following substitutions may be made: (1) a project labor agreement in place of a collective bargaining agreement, and (2) an independent, nationally recognized labor organization in place of a labor organization affiliated with the Building and Construction Trades Council of the AFL-CIO. Such contractors also shall comply with all requirements in Paragraph 4.5 of the Lease. Landlord shall approve or disapprove any proposed contractor or construction contract within three (3) Business Days after Landlord’s receipt of a written request for such approval and containing the full name and address of the contractor and/or a complete copy of the construction contract (as applicable). Without limiting the foregoing, Tenant’s contract with its general contractor for the construction of the Expansion Improvements shall be subject to the approval of the Landlord as to both form and content, which approval shall not be unreasonably withheld or delayed.

(b) All Expansion Improvements, regardless of which party constructed or paid for them, shall become the property of Landlord and shall remain upon and be surrendered with the Premises upon the expiration or earlier termination of this Lease; provided that, at Landlord’s election and upon notice to Tenant, Tenant shall be required to remove all or any portion of the Expansion Improvements (including Telecommunication Facilities) upon the expiration or earlier termination of the Lease. Notwithstanding the foregoing, except as provided below in this Section 8(b), if Tenant’s submission of its Expansion Plans and Specifications to the Landlord for approval is accompanied by a written request that Landlord identify any Expansion Improvements that Landlord may require Tenant to remove upon the expiration or earlier termination of the Lease and such request includes a notice at the top of the page having a heading in at least 12-point type, bold and all capital letters stating “LANDLORD’S APPROVAL MUST IDENTIFY ANY EXPANSION IMPROVEMENTS WHICH LANDLORD MAY REQUIRE TENANT TO REMOVE UPON THE EXPIRATION OR EARLIER TERMINATION OF THE LEASE”, then Landlord shall identify such Expansion Improvements (if any) by written notice to Tenant given at the time of Landlord’s approval of the Expansion Plans and Specifications, and Tenant shall not be required to remove any such Expansion Improvements not so identified. However, Tenant reserves the right to amend and resubmit the Expansion Plans and Specifications within seven (7) days after receipt of Landlord’s approval thereof. In all events, Landlord reserves the right to require Tenant to remove any wiring and cabling installed by Tenant. All unattached and moveable partitions, trade fixtures, moveable equipment or furniture located in the Premises and acquired by or for the account of Tenant which can be removed without damage to the Building or Premises, and all personalty brought into the Premises by Tenant shall be owned by Tenant and may be removed by Tenant subject to and in accordance with Paragraph 4.7 of the Lease, including but not limited to all servers, server racks, generators, supplemental HVAC units, furniture, phone and TV systems.

(c) Tenant shall be solely responsible for the design and construction of the Expansion Improvements. Notwithstanding Landlord’s review and approval of the Expansion Plans and Specifications, Landlord shall have no liability to Tenant or to any other person for errors or omissions in the Expansion Plans and Specifications (Landlord’s review and approval of the Expansion Plans and Specifications being for Landlord’s own purposes). Tenant shall indemnify, defend, protect and hold Landlord and Landlord’s Agents harmless from all Claims which arise in any way, directly or indirectly from or in connection with the design and construction of the Expansion Improvements, including without limitation, claims arising from the work of Tenant’s architect, engineer, employees or agents, unless such design was mandated by Landlord over Tenant’s specific written objections thereto.

(d) Landlord shall grant an allowance to Tenant in an amount up to the Expansion Tenant Improvement Allowance (as defined in Section 2 hereof) to be used solely to reimburse the Tenant for the Expansion Tenant Improvement Costs and to pay the Expansion Construction Monitoring Fee. Subject to the terms and conditions hereof, the Expansion Tenant Improvement Allowance shall be available for disbursement in monthly draws (each an “Expansion Tenant Allowance Advance”) plus one (1) final draw of the Expansion Retainage (as defined below) in the following manner. At least fifteen (15) Business Days before the date upon which the Tenant desires an Expansion Tenant Allowance Advance or an advance of the Expansion Retainage, the Tenant shall submit an itemized requisition (an “Expansion Requisition”) on a form acceptable to the Landlord in its reasonable discretion, stating the amount of the advance, the items(s) to be reimbursed from the proceeds thereof, and the date upon which the advance is desired. Each Expansion Tenant Allowance Advance shall be subject to retainage in the amount of ten percent (10%) (the “Expansion Retainage”). Landlord’s obligation to make any Expansion Tenant Allowance Advance shall be subject to Tenant’s satisfaction of all of the following conditions other than item number (6), and Landlord’s obligation to advance the Expansion Retainage shall be subject to Tenant’s satisfaction of each and all of the following conditions numbered (1) through (6): (1) Tenant shall have submitted to Landlord a certification signed by Tenant’s architect certifying that all work on the Expansion Improvements which has been completed through the date of such certification (which shall be no earlier than the date of the subject Expansion Requisition) has been completed in all material respects in accordance with Expansion Plans and Specifications approved by the Landlord and attaching thereto an executed waiver or release of liens from Tenant’s general contractor for the Expansion Improvements for all work performed and materials delivered through the date of such Expansion Requisition, which

waiver and release shall be in such form as Landlord may reasonably require, (2) Tenant shall have provided Landlord with executed waivers or releases of liens from each of Tenant’s subcontractors and suppliers for all work performed and materials delivered through the date of such Expansion Requisition, which waivers and releases shall be in such form as Landlord may reasonably require, (3) Tenant shall have submitted to Landlord a certification of Tenant’s general contractor for the Expansion Improvements identifying each contractor, subcontractor and supplier who performed labor and/or supplied materials for the Expansion Improvements through the date of such Expansion Requisition, (4) Tenant shall have furnished Landlord with copies of third party invoices, for all work performed and materials delivered which are included in such Expansion Requisition, (5) at the time of such Expansion Tenant Allowance Advance there shall exist no event which is, or solely with the passage of time and/or giving of notice would be, an Event of Default, and (6) with respect to the advance of the Expansion Retainage, Tenant shall have submitted to Landlord an issued and effective certificate of occupancy for the Expansion Premises for the Permitted Use and a certification signed by Tenant’s architect certifying that the Expansion Improvements have been completed in accordance with Expansion Plans and Specifications approved by the Landlord and attaching thereto executed final waivers or releases of liens from Tenant’s general contractor and each of Tenant’s subcontractors and suppliers in connection with the Expansion Improvements in such form as Landlord may reasonably require, plus a certificate of Tenant’s general contractor identifying each contractor, subcontractor and supplier who performed labor and/or supplied materials for the Expansion Improvements. The foregoing items (1) through (6) above are herein collectively referred to as the “Expansion Tenant Allowance Conditions”. Subject to satisfaction of all of the Expansion Tenant Allowance Conditions applicable to a particular Expansion Tenant Allowance Advance and/or advance of the Expansion Retainage, Landlord shall pay to Tenant, within fifteen (15) Business Days after receipt by Landlord of a written request from Tenant for an Expansion Tenant Allowance Advance or the Expansion Retainage (as applicable) in accordance with the foregoing (or on such later date as requested by Tenant), the lesser of (a) the full amount of the remaining undisbursed Expansion Tenant Improvement Allowance (after taking into account all Expansion Tenant Allowance Advances and deducting the aggregate amount of any undisbursed Expansion Retainage, except in the case of a final Expansion Requisition for the Expansion Retainage, and any unpaid balance of the Expansion Construction Monitoring Fee), if the aggregate sum of the invoices submitted pursuant to item (4) above equals or exceeds the full amount of the Expansion Tenant Improvement Allowance, or (b) the aggregate sum of invoices submitted pursuant to item (4) above (less the aggregate amount of any undisbursed Expansion Retainage, except in the case of a final Expansion Requisition for the Expansion Retainage, and any unpaid balance of the Expansion Construction Monitoring Fee), if said aggregate sum is less than the full amount of the Expansion Tenant Improvement Allowance. Except as and to the extent expressly provided in Section 8(f) hereof, Tenant shall not be entitled to any credit, trade off or cash payment for any unused portion of the Expansion Tenant Improvement Allowance, and Landlord shall have no obligation to Tenant with respect to any such unused portion of the Expansion Tenant Improvement Allowance. Further, notwithstanding anything herein to the contrary, in the event that Tenant has not completed the Expansion Improvements and/or satisfied all of the conditions for payment of the Expansion Tenant Improvement Allowance on or before April 1, 2014 (subject to a day for day extension for delays caused solely by Force Majeure, casualty and Landlord Delay) (time being of the essence), Landlord shall have no further obligation to make any Expansion Tenant Allowance Advance.

(e) In all events, on or before April 1, 2014 (subject to a day for day extension for delays caused solely by Force Majeure, casualty and Landlord Delay) (time being of the essence), (i) Tenant shall complete the Expansion Improvements, and (ii) if not already done pursuant to Section 8(d) above, Tenant shall submit to Landlord an issued and effective certificate of occupancy for the Expansion Premises for the Permitted Use and a certification signed by Tenant’s architect certifying that the Expansion Improvements have been completed in accordance with Expansion Plans and Specifications approved by the Landlord, together with executed final waivers or releases of liens from Tenant’s general contractor and each of Tenant’s subcontractors and suppliers in connection with the Expansion Improvements in such form as Landlord may reasonably require, plus a certificate of Tenant’s general contractor identifying each contractor, subcontractor and supplier who performed labor and/or supplied materials for the Expansion Improvements.

(f) Upon completion of the Expansion Improvements and application of the Expansion Tenant Improvement Allowance against the Expansion Tenant Improvement Costs and the Expansion Construction Monitoring Fee, the unexpended and unapplied balance of the Expansion Tenant Improvement Allowance (if any) up to the maximum aggregate amount provided for in Section 8(g) hereof shall be available to Tenant in a single draw to reimburse Tenant for Expansion Tenant Expenditures upon receipt of a draw request (an “Expansion Tenant Expenditure Draw Request”) therefor in form and substance satisfactory to Landlord together with paid invoices, bills of sale, and any other documentation reasonably requested by Landlord. Except as provided in the immediately preceding sentence, Tenant shall not be entitled to receive any rent abatement, credit or payment on account of any unexpended portion of the Expansion Tenant Improvement Allowance.

(g) In no event shall the aggregate amount of the Expansion Tenant Improvement Allowance applied against or used for Expansion Tenant Expenditures exceed an amount equal to One Hundred Thirty-Three Thousand Eight Hundred Fifty-Six and 25/100 Dollars ($133,856.25) (based upon Six and 25/100 Dollars ($6.25) per rentable square foot of the Expansion Premises). Notwithstanding anything to the contrary contained herein, in the event that Tenant has not submitted an Expansion Tenant Expenditure Draw Request to Landlord with all required supporting documentation by April 1, 2014 (time being of the essence), Landlord shall have no further obligation to fund or otherwise advance any of the Expansion Tenant Improvement Allowance for any Expansion Tenant Expenditures.

Such amendment shall be in form and substance satisfactory to the Landlord, and the failure to deliver such amendment to the Landlord at or prior to the execution hereof shall constitute an Event of Default under the Lease.

(b) The Paragraph 3.3.2 of the Lease is hereby amended by deleting in its entirety the table which sets forth the Reduction Dates, the required amount of the Letter of Credit, and the reduction amounts of the Letter of Credit, and substituting in its stead the following table:

Notwithstanding anything to the contrary contained herein and/or in the Lease, at Landlord’s option Tenant’s payment of Estimated Operating Costs Allocable to the Premises, Operating Costs Allocable to the Premises, Estimated Property Taxes Allocable to the Premises, and Property Taxes Allocable to the Premises shall be calculated and payable separately for the Initial Premises and the Expansion Premises in the same manner that such amounts are calculated and payable for the Premises as provided in the Lease,

11. Parking. The Lease is hereby amended by deleting Paragraph 4.11 thereof in its entirety and substituting the following in its stead:

“4.11 Parking. Tenant shall have the nonexclusive privilege to use parking spaces on the Land in common with other tenants of Landlord, but only in areas reasonably designated by Landlord and only on a first-come-first-served basis. In addition, provided that the Original Tenant has not assigned this Lease nor sublet more than twenty-five percent (25%) of the Premises then demised to Tenant under this Lease (excluding transfers to Permitted Transferees), Tenant shall be granted one (1) reserved parking space (the “Reserved Space”) in front of the Building for the use of the Chief Executive Officer of the Original Tenant. The Reserved Space shall be designated by a sign stating “Reserved” to be installed by Landlord at Tenant’s Expense All of Tenant’s parking privileges shall be subject to the rules and regulations relating to parking adopted by Landlord from time to time. Landlord shall have the right to grant designated, reserved parking stalls to other tenants in the Building. In no event shall the number of parking stalls used by Tenant and Tenant’s Agents (including the Reserved Space) exceed the number of stalls allocated to Tenant in the definition of the Parking Ratio, provided, however, except with respect to the Reserved Space nothing in this sentence shall be deemed to alter the first-come-first-served basis of parking as provided in this paragraph 4.11. Landlord shall have no obligation whatsoever to monitor or police the parking or other common areas, except that Landlord shall use commercially reasonable efforts to monitor and enforce the use of the parking areas with respect to the parking ratio stated in this Lease.”

12. Right of First Refusal. Paragraph 6.20 of the Lease is hereby deleted in its entirety and the following is substituted in its stead:

6.20 Right of First Refusal.

6.20.1 Pursuant to the terms, conditions and limitations set forth in this paragraph 6.20, Tenant shall have a right of first refusal (the “Right to First Refusal”) with respect to the remainder of the second (2nd) floor of the Building (the “Second Floor Space”).

6.20.2 When Landlord receives an offer to lease any Second Floor Space from any third party which Landlord desires to accept (expressly including such offers which Landlord has solicited and which a third party has indicated it will accept) (each, an “Offer”), Landlord shall first present such Offer, in writing, to Tenant, and Tenant shall thereafter have five (5) Business Days in which to accept that Offer by delivery of written notice to Landlord. If Tenant fails to deliver to Landlord written acceptance of any Offer within the five (5) Business Day period set forth herein, then Tenant’s rights with respect to such Offer and the space referenced therein shall be void, and Landlord shall be free to lease the space that was the subject of such Offer to any third party.

6.20.3 In the event that the particular Offer from any third party includes space in the Building in addition to the applicable Second Floor Space, Landlord shall present such additional space to Tenant as part of the Offer (with any space presented to Tenant under this paragraph 6.20, whether Second Floor Space or other additional space, being “ROFR Space”). The Right of First Refusal shall apply to the entire portion of the ROFR

Space that is the subject of any Offer that is presented to Tenant, and the Right of First Refusal may not be exercised by Tenant with respect to only a portion thereof (so that if the Offer includes Second Floor Space and other additional space, Tenant may only accept the entirety of the Second Floor Space and such additional space).

6.20.4 If Tenant declines to exercise such Right of First Refusal with respect to any particular Second Floor Space, and an offer from a different third party prospect is thereafter offered to Landlord with respect to the same Second Floor Space that Landlord desires to accept, Landlord shall have no obligation to re-offer such Second Floor Space to Tenant on the terms offered by such different prospect (nor shall Landlord have any similar obligation with respect to any additional offers from additional prospects received by Landlord with respect to the particular Second Floor Space).

6.20.5 If Tenant validly exercises the Right of First Refusal provided in this Lease, the parties shall execute an amendment to this Lease adding the ROFR Space to the Premises on the terms set forth in the Offer. If the term of the ROFR Space included in the Offer extends further than the Lease Term with respect to the then Premises, Tenant’s leasing of the ROFR Space shall be for the duration included in the Offer (on the economic terms applicable thereto set forth in the Offer). Except as otherwise set forth in the Offer, the terms applicable to the then existing Premises shall apply to the ROFR Space (provided that Tenant shall not have any right to the Extension Option with respect to the ROFR Space or any other extension right, nor shall Landlord have any obligation to make any improvements to the ROFR Space or provide any free rent, improvement allowance, or any other type of allowance, in each case unless set forth in the Offer). Notwithstanding the foregoing, an otherwise valid exercise of the Right of First Refusal contained in this Lease shall be fully effective, whether or not such confirmatory documentation is executed, and Tenant’s tenancy of such ROFR Space shall be subject to all the rights and obligations of the parties under this Lease.
