NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Landlord and Tenant hereby covenant and agree as follows:

“The term “Monthly Base Rent” shall mean the Monthly Base Rent set forth in the rent schedule below.

“1.5    Lease Expiration Date: March 31, 2019.”

(a)Section 1.7 of the Lease is hereby deleted in its entirety and the following shall be inserted in lieu thereof:

“1.7    Security: Sixty Two Thousand Five Hundred and No/100 Dollars ($62,500.00)     Letter of Credit.”

(b)The second, third and fourth sentences of Section 5.1 of the Lease are hereby deleted in their entirety and the following shall be inserted in lieu thereof:

“The Stated Amount of the Letter of Credit shall be Sixty Two Thousand Five Hundred and No/100 Dollars ($62,500.00).”

“4.    Common Area Expenses and R&D Building Expenses

4.1.    Payment of Common Area Expenses and R&D Building Expenses. Tenant will pay, as Additional Rent and in the manner this Section 4 describes, (i) Tenant’s Share of Common Area Expenses, and (ii) Tenant’s Share of R&D Building Expenses, in each case, for each calendar year of the Term. Landlord will prorate Tenant’s Share of Common Area Expenses and Tenant’s Share of R&D Building Expenses for the calendar year in which this Lease terminates as of the termination date, as applicable, on a per diem basis based on the number of days of the Term within such calendar year.

4.2.    Estimation of Tenant’s Share of Common Area Expenses and Tenant’s Share of R&D Building Expenses. Landlord will deliver to Tenant a written estimate of the following for each calendar year of the Term: (a) Common Area Expenses and R&D Building Expenses, (b) Tenant’s Share of Common Area Expenses and Tenant’s Share of R&D Building Expenses and (c) the annual and monthly Additional Rent attributable to Tenant’s Share of Common Area Expenses and Tenant’s Share of R&D Building Expenses. Landlord may re-estimate Common Area Expenses and R&D Building Expenses from time to time during the Term. In such event, Landlord will re-estimate the monthly Additional Rent attributable to Tenant’s Share of Common Area Expenses and Tenant’s Share of R&D Building Expenses to an amount sufficient for Tenant to pay the re-estimated monthly amount over the balance of the calendar year. Landlord will notify Tenant of the re-estimate and Tenant will pay the re-estimated amount in the manner provided in the last sentence of Section 4.3.

4.3.    Payment of Estimated Tenant’s Share of Common Area Expenses and Tenant’s Share of R&D Building Expenses. Tenant will pay the amount Landlord estimates as Tenant’s Share of Common Area Expenses and Tenant’s Share of R&D Building Expenses under Section 4.2 in equal monthly installments, in advance, on the first day of each and every calendar month during the Term. If Landlord has not delivered the estimates to Tenant by the first day of January of the applicable calendar year, Tenant will continue paying Tenant’s Share of Common Area Expenses and Tenant’s Share of R&D Building Expenses based on Landlord’s estimates for the previous calendar year. When Tenant receives Landlord’s estimates for the current calendar year, Tenant will pay the estimated amount for such calendar year (less amounts Tenant paid to Landlord in accordance with the immediately preceding sentence) in equal monthly installments over the balance of such calendar year, with the number of installments being equal to the number of full calendar months remaining in such calendar year.

4.4.    Confirmation of Tenant’s Share of Common Area Expenses and Tenant’s Share of R&D Building Expenses. After the end of each calendar year within the Term, Landlord will determine the actual amount of Tenant’s Share of Common Area Expenses and Tenant’s Share of R&D Building Expenses for the expired calendar year and deliver to Tenant a written statement of such amount. If Tenant paid less than the amount of Tenant’s Share of Common Area Expenses and/or Tenant’s Share of R&D Building

Expenses specified in the statement, Tenant will pay the difference to Landlord as Additional Rent in the manner described in Section 3.2. If Tenant paid more than the amount of Tenant’s Share of Common Area Expenses and/or Tenant’s Share of R&D Building Expenses specified in the statement, Landlord will, at Landlord’s option, either (a) refund the excess amount to Tenant, or (b) credit the excess amount against Tenant’s next due monthly installment or installments of estimated Additional Rent. If Landlord is delayed in delivering such statement to Tenant, such delay does not constitute Landlord’s waiver of Landlord’s rights under this section. Notwithstanding the foregoing, if Tenant paid more than the amount of Tenant’s Share of Common Area Expenses and/or Tenant’s Share of R&D Building Expenses specified in the statement and the Term has expired, Landlord shall refund such excess amount to Tenant within forty five (45) days of the end of the Term.

4.5.    Tenant’s Inspection and Audit Rights. If Tenant desires to audit Landlord’s determination of the actual amount of Tenant’s Share of Common Area Expenses and/or Tenant’s Share of R&D Building Expenses for any calendar year, Tenant must deliver to Landlord written notice of Tenant’s election to audit within 30 days after Landlord’s delivery of the statement of such amount under Section 4.4. If such notice is timely delivered, and provided that no default then exists under this Lease, then Tenant (but not any subtenant or assignee) may, at Tenant’s sole cost and expense, cause a certified public accountant reasonably acceptable to Landlord to audit Landlord’s records relating to such amounts on a non-contingent basis. Such audit will take place during regular business hours at a time and place reasonably acceptable to Landlord (which may be the location where Landlord maintains the applicable records). Landlord shall deliver copies of such records to Tenant, to the extent reasonably practicable, in the event traveling to the location of the records is cost-prohibitive. Tenant’s election to audit Landlord’s determination of Tenant’s Share of Common Area Expenses and/or Tenant’s Share of R&D Building Expenses is deemed withdrawn unless Tenant completes and delivers the audit report to Landlord within 60 days after the date Tenant delivers its notice of election to audit to Landlord under this section. If the audit report shows that the amount Landlord charged Tenant for Tenant’s Share of Common Area Expenses and/or Tenant’s Share of R&D Building Expenses was greater than the amount this Section 4 obligates Tenant to pay, unless Landlord reasonably contests the audit, Landlord will refund the excess amount to Tenant, together with interest on the excess amount (computed at 10% per annum from the date Tenant delivers its dispute notice to Landlord) within 30 days after Landlord receives a copy of the audit report. If the audit report shows that the amount Landlord charged Tenant for Tenant’s Share of Common Area Expenses and/or Tenant’s Share of R&D Building Expenses was less than the amount this Section 4 obligates Tenant to pay, Tenant will pay to Landlord, as Additional Rent, the difference between the amount Tenant paid and the amount determined in the audit. Pending resolution of any audit under this section, Tenant will continue to pay to Landlord all estimated amounts of Tenant’s Share of Common Area Expenses and/or Tenant’s Share of R&D Building Expenses in accordance with Section 4.3. Tenant must keep all information it obtains in any audit strictly confidential and may only use such information for the limited purpose this section describes and for Tenant’s own account.

4.6.    Adjustment for Variable Common Area Expenses and R&D Building Expenses. If all of the rentable area of the R&D Building is not occupied at all times during any calendar year pursuant to

leases under which the terms and rents have commenced for such calendar year, Landlord will reasonably and equitably adjust its computation of Common Area Expenses and R&D Building Expenses for that calendar year to include all components of Common Area Expenses and R&D Building Expenses that vary based on occupancy in an amount equal to Landlord’s reasonable estimate of the amount Tenant would have paid for such components of Common Area Expenses and R&D Building Expenses had all of the rentable area of the R&D Building been so occupied at all times during such calendar year.

4.7.    Personal Property Taxes. Tenant will pay, prior to delinquency, all taxes charged against Tenant’s Personal Property. Tenant will use all reasonable efforts to have Tenant’s Personal Property taxed separately from the Property. If any of Tenant’s Personal Property is taxed with the Property, Tenant will pay the taxes attributable to Tenant’s Personal Property to Landlord as Additional Rent.

4.8.    Rent Tax. Tenant will pay to Landlord all Rent Tax due in connection with this Lease or the payment of Rent hereunder, which Rent Tax will be paid by Tenant to Landlord concurrently with each payment of Rent made by Tenant to Landlord under this Lease.

(a)Section 11.1 of the Lease is hereby deleted in its entirety and the following shall be inserted in lieu thereof:

“Except for Landlord’s obligations described in Section 11.2, Tenant, at its sole cost and expense, will keep and maintain the Premises in good, clean, sanitary, neat and fully operative condition and repair, reasonable wear and tear excepted. Tenant’s obligations under this section include, without limitation, maintenance and repair (including replacements) of all: (a) non-structural interior portions, systems and equipment; (b) interior surfaces of exterior walls; (b) interior moldings, partitions and ceilings; (c) slabs, floors and structural columns; (d) windows, plate glass, and doors; and (e) electrical, lighting, mechanical, plumbing, heating and air conditioning systems, facilities, fixtures and components serving exclusively the Premises. Any repairs or replacements performed by Tenant

must be at least equal in quality and workmanship to the original work and be in accordance with all applicable laws, regulations and restrictions, including but not limited to all Declarations, Building Regulations, and Environmental Permits. Tenant will at all times and at Tenant’s sole cost and expense keep a preventative maintenance and repair contract in force and effect for the heating, air conditioning and ventilation system serving the Premises. For the avoidance of doubt, Tenant shall maintain and repair, at its sole cost and expense, the HVAC units servicing the Premises that are marked on the plan to be delivered by Landlord to Tenant upon completion of the Demising Work. Such contract (including without limitation the schedule and scope of services provided and the identity and capabilities of the contractor) must be acceptable to Landlord in Landlord’s reasonable discretion. Tenant will not commit any nuisance or waste in, on or about the Premises, the Common Area, or the Property. Notwithstanding anything to the contrary above, if any Tenant Damage occurs Landlord may, at Landlord’s option and in Landlord’s sole discretion, require Tenant to (a) pay to or reimburse Landlord for the actual reasonable cost of any repairs or replacements necessitated by such Tenant Damage which are performed by Landlord, and/or (b) perform, at Tenant’s sole cost and expense, any repairs or replacements necessitated by such Tenant Damage which are not performed by Landlord.

(b)The following is hereby added at the end of Section 11.2 of the Lease:

“Notwithstanding anything to the contrary in this Section 11.2, Landlord will keep and maintain in good order, condition and repair, reasonable wear and tear excepted, the (a) exterior surfaces of the exterior walls (excluding windows and plate glass) and roof of the R&D Building, (b) structural integrity of the footings, foundation, exterior walls and roof of the R&D Building, and the (c) Common Area. Landlord will also perform any repairs or replacements to the Premises or Property necessitated by damage or destruction of the Property, subject to the provisions of Section 18 of the Lease. Neither Monthly Rent nor Additional Rent will be reduced, nor will Landlord be liable, for loss or injury to or interference with Tenant’s property, profits or business arising from or in connection with Landlord’s performance of its obligations under this Section 11.2. If any governmental authority requires any alterations, additions, improvements, or decorations (collectively “Alterations”) to the Property or the Premises as a result of Tenant’s particular use of the Premises (whether or not it is a Permitted Use) or as a result of any Alteration to the Premises made by or on behalf of Tenant or if Tenant’s particular use of the Premises subjects Landlord or the Property to any obligation under any applicable laws or regulations, Tenant will pay the cost of all such Alterations or the cost of compliance, as the

case may be. If any such Alterations involve either (a) the structural, mechanical, electrical, plumbing, fire/life safety or heating, ventilating and air conditioning systems of the Building, or (b) any portion of the Property outside of the interior of the Premises (collectively “Structural Alterations”), Landlord will make such Structural Alterations, provided that Landlord may first require Tenant to deposit with Landlord an amount sufficient to pay the cost of such Structural Alterations (including, without limitation, reasonable overhead and administrative costs). If the Alterations are not Structural Alterations, Tenant will make the Alterations at Tenant’s sole cost and expense in accordance with Section 12 of the Lease.

“Notwithstanding anything to the contrary in Section 12.1(a) of the Lease, a Pre-Approved Change shall not include any Tenant Changes that consist of Structural Alterations.”

“Landlord shall, at its sole cost and expense, perform the work necessary to provide meters or submeters to measure Tenant’s consumption of utilities at the Premises. Notwithstanding anything to the contrary herein, Landlord shall, in Landlord’s reasonable discretion, bill Tenant for such charges directly or require Tenant to pay charges directly (in which event such charges shall be deemed Additional Rent under the Lease) or to the applicable utility companies. Furthermore, until the date Landlord procures a third party tenant for any portion of the Surrendered Premises and the term of the lease with such third-party tenant commences (the “Demising Effective Date”), Tenant shall be responsible for direct payment to the applicable utility companies of all charges related to steam, electricity, water, sewer, gas and other utility charges for the entire R&D Building (and not solely limited to the Overland Premises).”

(a)Section 18.1 of the Lease is hereby deleted in its entirety and the following shall be inserted in lieu thereof:

“Except as specifically provided in Section 18.2 below, in case of damage to or destruction of the Premises, whether or not by a risk required to be covered by insurance as set forth in Section 20 of this Lease, this Lease shall not terminate and Landlord shall promptly restore, rebuild, replace or repair (hereinafter referred to as “Restore” or “Restoration”) the Premises to substantially the same condition as existed immediately prior to such damage or destruction, subject, in any event, to Landlord’s receipt of all applicable insurance proceeds pertaining to the insurance maintained by Landlord hereunder. Such Restoration shall be commenced promptly, subject to Landlord’s receipt of all governmental approvals and/or insurance and/or condemnation proceeds required to proceed with the restoration (which Landlord shall use diligent efforts to obtain) and subject to Force Majeure.”

(b)The clause “in which event Tenant shall have no obligation to Restore the Premises” in the first sentence of Section 18.2 of the Lease and the last sentence of Section 18.2 of the Lease are hereby deleted in their entirety.

(c)Section 18.3 of the Lease is hereby deleted in its entirety and replaced with “Intentionally Omitted.”

supplemented, discharged, cancelled or terminated orally or by any course of dealing, or in any manner other than by an agreement in writing, signed by the party to be charged.
