Commencing with the monthly installment of Base Rent payable for January, 2019, and thereafter on the first (1st) day of each month during the Term, Tenant shall pay to Landlord one-twelfth (1/12th) of the amount of Landlord's then current estimate of Expense and Tax Increases. Within 180 days after the end of each calendar year following the Base Operating Expense Year and within 180 days after the end of the Term, Landlord shall submit to Tenant a statement, prepared by Landlord, of the actual Expense and Tax

Increases for the preceding calendar year (or partial calendar year in the event the Term shall end on a date other than a December 31^st), and the figures used for computing Tenant's Proportionate Share for the preceding calendar year, and if Tenant's Proportionate Share of Expense and Tax Increases so stated for such period is (i) more than the amount paid for such period, Tenant shall pay to Landlord the deficiency within thirty (30) days after submission of such statement, or (ii) less than the amount paid for such period, at Landlord's sole election, Tenant shall be entitled to a credit in the amount of such excess against amounts next coming due under this Paragraph or Landlord shall refund the amount of such overpayment to Tenant (or a refund of such excess in the case of the end of the term of this Lease). Any such adjustment shall survive the expiration or earlier termination of the Term. If Landlord shall furnish such estimate subsequent to the commencement of any such calendar year, then, until the first (1st) day of the month following the month in which such estimate is furnished to Tenant, Tenant shall pay to Landlord on the first (1st) day of each month an amount equal to Tenant's monthly payment with respect to Tenant's Proportionate Share of Expense and Tax Increases for the last month of the preceding calendar year.

3.4.Electricity. Tenant shall pay to Landlord, as Additional Rent hereunder, an amount equal to $4.00 per year for each rentable square foot of the Leased Premises, which shall be payable in equal monthly installments as of the first day of each month of the Term and, when applicable, shall be tendered together with the regular monthly payments of Base Rent and Additional Rent.

3.5.Absolute Obligation to Pay; No Set-Off. Tenant's obligation to make full and prompt payments of all Base Rent and Additional Rent when owed under the terms of this Lease is absolute. Base Rent and Additional Rent shall be paid without set-off, withdrawal or deduction of any nature.

3.6.Partial Payments. Any payment of Base Rent and/or Additional Rent which is less than the amount then due and owing to Landlord will be considered a payment against the oldest outstanding rental obligation and Landlord may accept such payment without affecting its rights to collect the balance owed.

3.7.Interest on Late Payments of Base Rent, Additional Rent or Other Amounts Due. Any Base Rent, Additional Rent or other amount which is owed by Tenant under this Lease and which is not paid within fifteen (15) days of the date when due shall carry interest at an annual rate (the “Default Rate”) equal to the lesser of (i) the highest rate allowed by law from the date which is fifteen (15) days after the date such Base Rent and/or Additional Rent or other amount was due until the date of payment, and (ii) eighteen percent (18%) per annum.

3.8.Bookkeeping and Audits. Landlord shall maintain books and records respecting gas, electricity, Operating Expenses and Property Taxes and determine the same in accordance with sound accounting and management practices, consistently applied. Tenant or its representative shall have the right to examine those books and records of Landlord and any managing agent reasonably necessary for purposes of auditing expenditures for gas, electricity, Operating Expenses and Taxes in question. Such examination shall take place during normal

business hours at the place or places where such records are normally kept. Each Annual Operating Expense Statement rendered to Tenant shall be considered final, unless Tenant has given written notice to Landlord of its intention to audit the books and records of Landlord, which notice must be given within forty five (45) days following Tenant’s receipt of such Annual Operating Expense Statement. In the event that Landlord and Tenant are unable to resolve the dispute within forty five (45) days following Landlord’s granting Tenant access to such books and records of the Landlord, then such dispute shall be submitted to an independent certified public accounting firm selected by Landlord, subject to Tenant’s reasonable approval of such firm, which approval shall not be unreasonably withheld or delayed. The certification by such independent certified public accounting firm as to the proper amount shall be final and conclusive as between Landlord and Tenant. Tenant shall promptly pay the fees and costs of such independent certified public accounting firm unless such certification determines that Tenant was overbilled by more than two (2%) percent in which case Tenant’s audit expenses will be paid by Landlord. Pending resolution of any such exceptions in the foregoing manner, Tenant shall continue paying, without prejudice to Tenant's position, Tenant's Pro Rata Share of gas, electricity, Operating Expenses and Taxes paid or incurred during the applicable period in the amounts determined by Landlord, subject to adjustment after any such exceptions are resolved.

3.9.Survival. The rights, obligations and liabilities of Landlord and Tenant under this Article 3 shall survive the expiration or earlier termination of this Lease for any reason.

4.2.Property Taxes. Tenant’s liability for the payment of Property Taxes is governed by Section 3.2 of this Lease.

4.3.Available Abatements of Real Property Taxes. Landlord shall use reasonable commercial efforts to assist Tenant’s efforts to obtain the benefit of any “Enterprise Zone” abatements of Property Taxes that may be available as a result of, relating to, or in connection with the Tenant’s occupancy of the Leased Premises or Tenant’s business operations therein (“Property Tax Abatements”). Landlord shall not be required to commence any adversarial proceeding, whether administrative or judicial, to obtain any ruling, file any appeal, or otherwise to defend any application and shall not be accountable to the Tenant for any of its efforts in seeking Property Tax Abatements. In the event that any Property Tax Abatements are secured, Landlord shall credit the amount of the Property Tax Abatements, net of all out-of-pocket costs, expenses and fees incurred by Landlord in securing such Property Tax Abatements, in equal installments to the Additional Rent payable by Tenant during the next six months after such Property Tax Abatements are received by or credited to Landlord by such taxing authority. Landlord makes no representations as to the availability of Property Tax Abatements and/or the Landlord’s rights with respect thereto.

4.4.Other Taxes and License Fees. Tenant shall pay before delinquency all license and permit fees and taxes that may be imposed upon the business of Tenant on the Leased Premises.

4.5.Survival. The rights, obligations and liabilities of Landlord and Tenant under this Article 4 shall survive the expiration or earlier termination of this Lease for any reason.

ARTICLE 6. ALTERATIONS

Subject to the approval of the Landlord, which approval may not be unreasonably withheld, Tenant may reconfigure the Leased Premises at any time during the Term. Tenant shall not otherwise make any alterations, additions or improvements in or to the Leased Premises except with Landlord's prior written consent, which consent will not be unreasonably withheld. Without limiting the generality of the foregoing, it shall not be unreasonable for Landlord to withhold its approval or consent or require modifications to any proposed reconfiguration, alterations, additions or improvements if there will be any effect upon or interference with the design or installation of any mechanical, electrical or other systems which interconnect to or could affect or be affected by mechanical, electrical, HVAC or other Building 4 systems.

Landlord shall respond to such a notice from Tenant in writing within twenty (20) days of receipt, and state whether or the extent to which such additions and improvements must be removed upon the termination of the Lease and such written response from Landlord shall be binding on the parties. Landlord acknowledges that Tenant has supplied certain equipment, as contained in Schedule B attached, and Tenant shall remove said equipment upon termination of this Lease.

6.3.Tenant's Removal of Trade Fixtures. Nothing in this Article shall prevent Tenant's removal of its trade fixtures upon the Expiration Date or earlier termination of this Lease in accordance with the terms hereof, but upon such removal, Tenant shall promptly, and at its own expense, repair and restore any damage caused by such removal.

6.4.Tenant's Compliance with Conditions of Construction. Tenant shall, before making any alterations, additions or improvements permitted hereunder, obtain all permits, approvals and certifications required by any governmental or quasi-governmental body or authority, and (upon completion) certificates of final approval and/or completion thereof, and shall deliver promptly copies of all such permits, approvals and certificates to Landlord. In performing any additions, alterations or improvements to the Leased Premises permitted hereunder, Tenant shall comply with all applicable laws, regulations and ordinances. Tenant agrees to carry, and will cause its contractors and subcontractors to carry, worker's compensation insurance in the amount required by law and general liability insurance with a limit of not less than One Million Dollars ($1,000,000.00) combined single limit per occurrence for bodily injury, personal injury and property damage liability.

6.5.Mechanic's Lien. If any mechanic's lien is filed against the Property, Building 4 or the Leased Premises for work claimed to have been done or materials claimed to have been furnished to or for the benefit of Tenant, whether related to work done pursuant to any provision of this Lease or otherwise, the lien, within forty five (45) days of its receipt of notice of such filing, shall be discharged by Tenant at Tenant's expense by filing a bond as required by law or by other reasonable means.

On or before the date that is one hundred twenty (120) days prior to the Expiration Date for the Term (the "Notice Date"), Tenant shall advise Landlord in writing that Tenant wishes to extend the term of this Lease (hereinafter referred to as “Tenant's Extension Notice”).
