Any of the above services may be performed by Landlord or its affiliates. Operating Expenses shall not include leasing commissions; repair costs paid by insurance proceeds or by any tenant or third party; the initial construction cost of the Building or any depreciation thereof; any debt service or costs related to sale or financing of the Property; tenant improvements provided for any tenant; leasing expenses; or any special services rendered to tenants (including Tenant) for which a separate charge is made.

(b) Capital Costs. The cost of any capital improvements to the Property made by Landlord that are designed to increase safety, to reduce Operating Expenses, or to comply with any governmental law or regulation imposed after the Commencement Date, amortized over such period as Landlord shall reasonably determine, together with a fixed annual interest rate equal to the Prime Rate plus 2% on the unamortized balance. The Prime Rate shall be the prime rate published in the Wall Street Journal on the date the construction is completed.

(c) Tenant’s Share of Operating Expenses. Operating Expenses incurred monthly times Tenant’s Percentage.

(d) Tenant’s Share of Capital Costs. Capital Costs incurred monthly times Tenant’s Percentage.

(iii) Estimate of Tenant’s Share of Expenses. From time to time as Landlord deems appropriate, Landlord shall give Tenant estimates of total monthly Tenant’s Share of Expenses and Tenant shall pay such estimated amount of Tenant’s Share of Expenses monthly as Additional Rent, subject to adjustment as provided in this Section 5. On or before May 15th of each calendar year, Landlord shall give Tenant a statement (the “Property Expenses Statement”) showing the total Operating Expenses and total Capital Costs for the prior calendar year, a calculation of Tenant’s Share of Expenses due for the prior calendar year and a summary of amounts already paid by Tenant for the prior calendar year. Any underpayment by Tenant shall be paid to Landlord within thirty (30) days after delivery of the Property Expenses Statement; any overpayment shall be credited equally against the next 12 installments of Base Rent due, provided that any overpayment shall be paid to Tenant within sixty (60) days if the Term has ended. No delay by Landlord in providing any Property Expenses Statement shall be deemed a waiver of Tenant’s obligation to pay Tenant’s Share of Expenses. In determining Operating Expenses and calculating Tenant’s Share of Expenses, Landlord may increase those elements of Operating Expenses that vary based primarily on the occupancy rate of the Building, as though the Building were 95% occupied and Tenant’s Share of Expenses shall be adjusted by Landlord to the amount that Landlord reasonably believes they would have been if 95% of the rentable area of the Building had been occupied.

(iv) Audit Rights. Within 30 days after Landlord furnishes its statement of actual Operating Expenses and Capital Costs (the “Audit Election Period”), Tenant may, at its expense, elect to audit Landlord’s Operating Expenses and Capital Costs for such calendar year only, subject to the following conditions: (1) there is no uncured Event of Default under this Lease; (2) in no event shall any audit be performed by a firm retained on a “contingency fee” basis; (3) the audit shall commence within 10 days after Landlord makes Landlord’s books and records available to Tenant’s auditor and shall conclude within 30 days after commencement; (4) the audit shall be conducted during Landlord’s normal business hours at the location where Landlord maintains its books and records and shall not unreasonably interfere with the conduct of Landlord’s business; and (5) Tenant and its accounting firm shall treat any audit in a confidential manner and shall each execute Landlord’s confidentiality agreement for Landlord’s benefit prior to commencing the audit. This Subsection shall not be construed to limit, suspend, or abate Tenant’s obligation to pay Rent when due. Landlord shall equally credit any overpayment determined by the final approved audit report against the next 12 installments of Rent due and owing by Tenant or, if no further Rent is due, refund such overpayment directly to Tenant within 30 days of determination. Likewise, Tenant shall pay Landlord any underpayment determined by the final approved audit report within 30 days of determination. The foregoing obligations shall survive the expiration or termination of this Lease. If Tenant does not give written notice of its election to audit Landlord’s Operating Expenses and Capital Costs for the calendar year during the Audit Election Period, Landlord’s Operating Expenses and Capital Costs for the applicable calendar year shall be deemed approved for all purposes, and Tenant shall have no further right to review or contest the same. The right to audit granted hereunder is personal to the initial Tenant named in this Lease and to any permitted assignee.

In the event of any contradictory language in the Lease related to the determination or calculation of rent owed, the foregoing language (described above) shall supersede and control.

6. Electricity Costs. Commencing on the Third Amendment Commencement Date, Landlord covenants and agrees to furnish building standard electrical service to the Premises sufficient to operate customary lighting, office machines and other equipment of similar low electrical consumption which shall be charged to Tenant pursuant to Section 4 of this Third Amendment of the Lease. Tenant covenants and agrees to pay Landlord estimated monthly electricity costs (“Electricity Costs”) as part of Additional Rent in addition to Base Rent. “Electricity Costs” shall mean the costs of all electricity used within the Premises and on or at the Property, together with any taxes and any maintenance charges thereon.

7. Signage. Landlord shall remove the Zion Oil & Gas exterior top of the Building signage on or after Lease expiration. Tenant shall reimburse Landlord up to $5,000.00 toward the signage removal.

8. Services Failure. For purposes of this Lease, a “Service Failure” shall mean any interruption, suspension or termination of services being provided to Tenant by Landlord, or by third-party providers pursuant to arrangements with Landlord, which are due to: (1) the application of Laws; (2) the failure, interruption or malfunctioning of any electrical or mechanical equipment, utility or other service to the Building or Property; (3) the performance of repairs, maintenance, improvements or alterations; or (4) the occurrence of any other event or cause whether or not within the reasonable control of Landlord. A Service Failure which continues for more than five (5) days shall give rise to an abatement of Rent for every day the Service Failure exists, and relieve Tenant from the obligation to fulfill any covenant or agreement in this Lease to pay Rent until the Service Failure no longer exists. In no event shall Landlord be liable to Tenant for any loss or damage, including the theft of Tenant’s Property, arising out of or in connection with any Service Failure or the failure of any Building safety services, personnel or equipment. Notwithstanding the foregoing, if a Service Failure occurs for HVAC, then Tenant shall immediately be able to abate Base Rent after 24 Hours of such failure.

9. ERCOT Fee. Landlord shall waive the Tenant’s ERCOT fee of Thirteen Thousand One Hundred Forty-Two and 77/100 Dollars ($13,142.77).

10. Security. Landlord shall be responsible for access control of the Building but does not guarantee that individual incidents will not occur.

11. Miscellaneous. With the exception of those terms and conditions specifically modified and amended herein, the herein referenced Lease shall remain in full force and effect in accordance with all its terms and conditions. In the event of any conflict between the terms and provisions of this Third Amendment and the terms and provisions of the Lease, the terms and provisions of this Third Amendment shall supersede and control.
