The cost estimate will include the actual costs quoted by no less than three (3) contractors competitively bid by Tenant. The cost estimate will separately state the Landlord construction management fee of three percent (3%) of the Third Expansion Tenant Improvement Allowance to be utilized for the Third Expansion Improvements to have Landlord manage the Third Expansion Improvements (the “Construction Management Fee”), which shall be deducted monthly based on the percentage of construction completed, commencing on the first day of the calendar month immediately following the date on which the Third Expansion Improvements are commenced. If the quoted estimated cost to construct both the Third Expansion Improvements in the Space Plan exceeds the total of Third Expansion Tenant Improvement Allowance, Tenant may cause the Architect to alter the Space Plan, provided, however, any such requests for changes to a Space Plan or requests the inclusion of materials or installations in the construction of the Third Expansion Improvements that delays the construction of the Third Expansion Improvements shall not extend the Third Expansion Premises Rent Commencement Date – Phase I or the Third Expansion Premises Rent Commencement Date – Phase II.

Tenant shall select with the prior approval of Landlord, not to be unreasonably withheld or delayed, a mutually agreed upon general contractor after a

competitive bidding process with no less than three (3) quotes. Tenant shall send summaries of all bids to Landlord. Tenant shall finalize the final cost to construct the Third Expansion Improvements in accordance with the Space Plan (the “Expansion Space Estimated Final Cost”) and, to the extent such cost exceeds the Third Expansion Tenant Improvement Allowance (the “Excess Amount”), Tenant shall have the right to make changes to the Space Plan as set forth above to limit the Excess Amount. The Excess Amount, if applicable, shall be funded by Tenant and paid to Landlord as follows: one-third (1/3) within thirty (30) days after Landlord’s approval of the Space Plan; one-third (1/3) sixty (60) days after Landlord’s approval of the Space Plan; and one-third (1/3) of the Excess Amount, ninety (90) days after Landlord’s approval of the Space Plan. Tenant shall be responsible for 100% of the payment of any additional costs or charges related to any change orders; provided, Landlord shall be required to reasonably approve any changes to the Space Plans or Third Expansion Premises Plans and Specifications. Except as set forth in Section 6(b), Tenant shall not be entitled to any cost savings or reimbursement in the event the actual costs and expenses to plan and construct the Third Expansion Improvements are less than the Third Expansion Tenant Improvement Allowance. Tenant shall not have the right to use any portion of the Third Expansion Tenant Improvement Allowance for the Premises, Expansion Premises or Second Expansion Premises. In no event shall more than fifteen percent (15%) of the Third Expansion Tenant Improvement Allowance be used toward the cost of the architectural and engineering services needed to prepare the Third Expansion Plans and Specifications and the Space Plans, moving expenses, signage, permit fees, architect fees, wiring and cabling, furniture, data, telephone, audio-visual, security, WiFi, “white noise”, internet and video systems, including, without limitation, any specialized supplemental cooling systems for any serve room or for any of the communications systems or other special rooms.

Tenant shall have no right to receive a payout of any unused Third Expansion Tenant Improvement Allowance, but it shall have the right to credit not more than ten percent (10%) of any unused portion of the Third Expansion Tenant Improvement Allowance toward Base Rent, provided Tenant (i) is not otherwise in default pursuant to the terms of the Lease and (ii) provides written notice to Landlord of Tenant’s desire to utilize such rent credit prior to the earlier to occur of (1) May 1, 2018 and (2) ninety (90) days after the Substantial Completion of the entire Third Expansion Premises, in which event the rent credit shall be applied on the immediately following month and shall continue until such rent credit has been applied in full. In the event Tenant shall be entitled to a rent credit for the partial amount of Base Rent payable with respect to any month, Tenant shall promptly pay the balance of the Base Rent for such month in accordance with the terms of the Lease.

(c)    Changes to Space Plan. Neither Tenant nor Landlord shall make material changes to the approved Space Plan or the work reflected in the approved Space Plan without the written consent of the other party, which consent shall not be unreasonably withheld, conditioned or delayed provided such changes do not materially alter the ability of the Tenant to use the Third Expansion Premises as intended, and do not increase the amount of the Excess Amount. Tenant shall have the right, at Tenant’s sole cost and expense, to have its construction representative at the Third Expansion Premises and the Initial Premises, Expansion Premises and Second Expansion Premises at all times during the construction of the Third Expansion Improvements to review and monitor the performance of same; provided, however, Tenant’s construction representative shall not interfere with or delay the construction of any portion of the Third Expansion Improvements.

        (d)     Removal of Third Expansion Improvements. Except for items addressed below, Tenant will have no obligation to remove its initial standard office Leasehold Improvements at the expiration or earlier termination of the Lease, which are approved by Landlord in advance at the time of Landlord’s approval of the Space Plan or upon submission of future requests to alter the Third Expansion Premises. Tenant agrees that all specialty equipment and alterations, such as lab/computer/server rooms, supplemental HVAC,

generators, UPS, staircases, raised floors, specialty conduits, private bathrooms, shower rooms, Tenant specific, non-standard office buildout items, and any alterations to the portions of the Third Expansion Premises which are currently common areas (e.g. the lobby of the Building, common hallways and common area bathrooms), shall be removed by Tenant at Landlord’s sole discretion upon surrender; provided, however, with respect to the lobby, Tenant shall not be obligated to restore the lobby of the Building to its original condition, but Tenant shall be obligated to remove any moveable partitions, trade fixtures, moveable equipment or furniture, including, without limitation, the reception desk, at the expiration of earlier termination of the Lease. In any event, Landlord hereby requires Tenant to remove any wiring and cabling installed by Tenant, including, without limitation, the Third Expansion Improvement Systems (as defined below). 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 material damage to the Building or Premises, and all personal items brought into the Premises by Tenant shall be owned by Tenant and will be removed by Tenant subject to and in accordance with Paragraph 4.7 of the Original Lease, including but not limited to all servers, server racks, generators, supplemental HVAC units, furniture, phone and TV systems.

        (e)    Substantial Completion. Landlord shall cause the Substantial Completion of each Phase I and Phase II of the Third Expansion Improvements. Landlord and Tenant acknowledge and agree that Landlord may achieve or cause the achievement of the Substantial Completion on a phased basis. For the purposes of this Amendment, “Substantial Completion” shall mean (i) the completion of the applicable Phase I or Phase II portion of the Third Expansion Improvements, subject only to the Final Punchlist (as defined below) and other uncompleted elements of construction, decoration, painting, millwork or other work and mechanical adjustment, and (ii) the issuance of a certificate of occupancy (or its equivalent) for the applicable Phase I or Phase II portion of the Third Expansion Premises for the Permitted Use and a certification signed by the Architect certifying that the applicable Phase I or Phase II portion of the Third Expansion Improvements have been completed in accordance with the Space Plan; provided, however, if Landlord is unable to obtain such certificate of occupancy (or its reasonable equivalent) by virtue of the fact that Tenant has not yet completed the installation of its Third Expansion Improvement Systems in the applicable Phase I or Phase II portion of the Third Expansion Improvements or for any other reason beyond the reasonable control of Landlord, then the applicable Phase I or Phase II portion of the Third Expansion Improvements shall be deemed Substantially Complete upon the certification of the Architect as stated in subsection (i), above, notwithstanding anything to the contrary in the foregoing.

Tenant shall be permitted to coordinate the installation of the Third Expansion Improvement Systems at the same time as Landlord is coordinating the Third Expansion Improvements as long as Tenant does not unreasonably interfere in any way with the construction process (by causing disharmony of labor relations at the Property, scheduling or coordination difficulties, etc.). In no event shall the Third Expansion Improvements include any Third Expansion Improvement Systems, the responsibility of which shall be Tenant’s. Tenant acknowledges that the ability to obtain the certificate of occupancy for the applicable Phase I or Phase II portion of the Third Expansion Premises depends upon the completion of all or a portion of Third Expansion Improvement Systems. Prior to the Third Expansion Commencement Date – Phase I or the Third Expansion Premises – Phase II, as applicable, Tenant shall comply with and perform, and shall cause its employees, agents, contractors, subcontractors, material suppliers and laborers to comply with and perform, all of Tenant’s obligations under the Lease and this Amendment.

of the customary punchlist type items, and any items of a seasonal nature, then remaining to be completed (the “Final Punchlist”) and Tenant shall cause such Final Punchlist to be completed in a diligent manner. If Tenant has elected to have Landlord manage the Third Expansion Improvements, then (i) the Final Punchlist work shall take place during regular business hours, but in a manner which will seek to minimize interruption of Tenant’s use and occupancy of the Premises, (ii) Landlord shall endeavor to complete all punch list work within thirty (30) days (or such longer period as is reasonably required with respect to applicable items), other than matters that cannot be completed owing to their seasonal nature, and subject to extension for Force Majeure and delays caused by Tenant, and (iii) any disputed Final Punchlist items identified as such during preparation of the Final Punchlist shall be completed by Landlord as aforesaid within thirty (30) days, subject to Landlord’s right to dispute whether such disputed items constitute a change to the applicable Phase I or Phase II portion of the Third Expansion Improvements.

(h)    Commencement of Base Rent Payments. Except due to a Landlord Delay in connection with the approval of the Space Plan and Third Expansion Plans and Specifications, if the applicable Phase I or Phase II portion of the Third Expansion Improvements have not been Substantially Completed by the Third Expansion Premises Rent Commencement Date – Phase I or the Third Expansion Premises Rent Commencement Date – Phase II, respectively, then Landlord shall not be subject to any penalty, claim or liability nor shall the validity of this Lease or the obligations of Tenant hereunder be in any way affected and Tenant shall be obligated to commence paying Base Rent for the Phase I or Phase II portion, as applicable. In no event shall Tenant occupy the Third Expansion Premises – Phase II prior to March 1, 2018.

(i)    Additional Rent Prior to Base Rent Commencement. At all times between the Third Expansion Commencement Date – Phase I and the Third Expansion Rent Commencement Date – Phase II, Tenant shall be responsible for direct payment of electricity, any other separately metered utilities, and any other Additional Rent due and payable with respect to Third Expansion Premises – Phase I. In no event shall Tenant be permitted to occupy the Third Expansion Premises – Phase II prior to the Third Expansion Commencement Date – Phase II, and, as such, shall not be responsible for the payment of electricity, any other separately metered utilities, and any other Additional Rent due and payable with respect to Third Expansion Premises – Phase II until the Third Expansion Commencement Date – Phase II.

Landlord shall use commercially reasonable efforts in connection with the construction of the Third Expansion Improvements, the Road Construction and the Parking Configuration to not unreasonably interfere with Tenant’s on-going operations at the Premises, including parking, ingress and egress. Tenant acknowledges that noise, vibrations, disturbance, relocation of Building access, and the temporary relocation of parking, ingress and egress shall not entitle Tenant to any rent abatement or to terminate this Lease. Except as otherwise expressly provided in the Lease, Landlord shall have no liability to Tenant nor shall Tenant’s obligations under this Lease be reduced or abated in any manner whatsoever by reason of any inconvenience, annoyance, interruption or injury to business arising from the Third Expansion Improvements, the Road Construction and the Parking Configuration.

Except as otherwise expressly provided in the Lease, Landlord shall have no liability to Tenant nor shall Tenant’s obligations under this Lease be reduced or abated in any manner whatsoever by reason of any inconvenience or annoyance arising from Landlord’s capital projects. Landlord shall use reasonable efforts to minimize any interference with Tenant’s business in the Premises due to Landlord completing the New Road.
