B.Landlord and Tenant desire to amend the Original Lease to, among other things, (i) expand the Existing Premises to include the Expansion Premises, and (ii) extend the term of the Original Lease, all in accordance with the terms and conditions set forth below.

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

1.Defined Terms. All capitalized terms used herein but not specifically defined in this Amendment shall have the meanings ascribed to such terms in the Original Lease. The term “Lease” where used in the Original Lease and this Amendment shall hereafter refer to the Original Lease, as amended by this Amendment.

2.Expansion of Premises. Effective as of the Effective Date (the “Expansion Date”), Tenant’s license of the Temporary Space pursuant to the First Amendment shall be terminated and of no further force or effect (provided each of the obligations set forth in the First Amendment which accrue prior to the Expansion Date including the payment of monetary amounts incurred prior to the Expansion Date and any indemnity obligations shall survive any such termination) rather the Existing Premises shall be expanded to include (and Tenant shall lease from Landlord) the Expansion Premises are approximately depicted on Exhibit A attached hereto. From and after the Expansion Date, the term “Premises” where used in the Lease shall mean the Existing Premises and the Expansion Premises collectively (for a total of approximately 8,562 rentable square feet). Landlord and Tenant agree that the rentable square footage of the Expansion Premises as set forth in this paragraph (and of the Existing Premises as set forth in Recital A above) shall be conclusive and binding on the parties hereto.

3.Lease Term. The Lease Term (with respect to both the Existing Premises and the Expansion Premises) shall expire on March 31, 2027 (the “Second Amendment Expiration Date”). The period commencing on the Expansion Date and ending on the Second Amendment Expiration Date is sometimes referred to herein as the “Expansion Term.”

Landlord and Tenant acknowledge that the aggregate amount of the Second Amendment Base Rent Credit equals Eighty-Three Thousand Three Hundred Twenty-Three and No/100 Dollars (i.e., $16,664.60 per month).

Tenant understands and agrees that the foregoing Second Amendment Base Rent Credit is conditioned upon Tenant’s not being in default under the Lease. If Tenant shall be in monetary or material non-monetary default under the Lease beyond any applicable notice and cure period, all Second Amendment Base Rent Credit shall be suspended until such default is cured and if Landlord elects to terminate the Lease pursuant to Section 19.2.1 of the Original Lease, then Tenant shall pay to Landlord the total

6.Condition of Premises.

(a)Subject to Section 6(b) below, Tenant shall lease the Expansion Premises (and Tenant shall continue to Lease the Existing Premises) “as is,” “with all faults,” and “without any representations or warranties.” Tenant agrees and warrants that it has investigated and inspected the condition of the entire Premises and the suitability of same for Tenant’s purposes, and Tenant hereby waives and disclaims any objection to, cause of action based upon, or claim that its obligations hereunder should be reduced or limited because of the condition of the Premises or the Building or the suitability of same for Tenant’s purposes.

(b)Landlord shall, on a one-time basis only, using Project-standard materials, specifications, guidelines and procedures (except to the extent otherwise designated by Landlord): perform certain demising, electrical and flooring work within the Premises as more particularly set forth on Exhibit B attached hereto (collectively, the “Landlord Work”). Notwithstanding anything to the contrary herein, Tenant shall be responsible for all costs and expenses incurred by Landlord in connection with the Landlord Work (including, without limitation, hard and soft construction costs and construction management and oversight fees equal to 3% of such costs) to the extent such costs and expenses exceed $34,360.00 in the aggregate (“Landlord’s Maximum Contribution”), and Tenant shall pay any such excess costs or expenses to Landlord within 20 days of written demand (which demand may be made by Landlord from time to time, including prior to the commencement of the Landlord Work based on Landlord’s reasonable estimate of the cost thereof). Notwithstanding anything to the contrary herein, except to the extent such costs are incurred as a result of Landlord’s gross negligence or willful misconduct or the contractor’s demonstrable errors, in no event shall Landlord be required to incur costs or expenses in connection with the Landlord Work in excess of Landlord’s Maximum Contribution. Tenant shall not (and Tenant shall ensure that its agents do not) knowingly interfere with the performance of the Landlord Work and shall reasonably cooperate with Landlord in connection with the performance of the Landlord Work, including, without limitation, by moving any equipment and other property which Landlord or its contractor may reasonably request be moved. Tenant acknowledges and agrees that the status of the Landlord Work shall in no manner impact the Expansion Date, which shall be the Effective Date irrespective of the status of the Landlord Work, or then condition of the Premises. Landlord shall use commercially reasonable efforts to complete the Landlord Work as soon as practicably possible after the Expansion Date, subject to Force Majeure and delays to the extent caused by

Tenant or any Tenant Party. Landlord shall be permitted to perform the Landlord Work during Tenant’s occupancy of the Existing Premises and Expansion Premises, without any obligation to pay overtime or other premiums. Landlord shall use commercially reasonable efforts to coordinate any materially disruptive work after normal business hours. Except to the extent caused by the gross negligence or willful misconduct of Landlord or its agents, representatives, employees, consultants or contractors, Tenant hereby agrees that the performance of the Landlord Work shall in no way constitute a constructive eviction of Tenant or entitle Tenant to any abatement of rent payable pursuant to this Lease. Landlord shall have no responsibility for, or for any reason be liable to Tenant, for any direct or indirect injury to or interference with Tenant’s business arising from the performance of the Landlord Work, nor shall Tenant be entitled to any compensation or damages for loss of the use of the whole or any part of the Premises resulting from the performance of the Landlord Work or Landlord’s or Landlord’s contractor’s or agent’s actions in connection with the performance of the Landlord Work, or for any inconvenience or annoyance occasioned by the performance of the Landlord Work or Landlord’s or Landlord’s contractor’s or agent’s actions in connection with the performance of the Landlord Work. Except to the extent caused by Landlord’s gross negligence or willful misconduct, Landlord shall not be responsible for any loss, including theft, damage or destruction to any work or material installed or personal property or equipment stored by Tenant at the Premises or for any injury to Tenant or any Tenant Party. Tenant shall be responsible for any increase in the cost of performing the Landlord Work resulting from any direct act or omission of Tenant or its agents, employees and contractors (and Tenant shall pay any such increased costs to Landlord upon demand). In addition, should Tenant request any change in the scope of the Landlord Work, then Tenant shall be responsible for all costs and expenses reasonably and properly incurred by Landlord in connection therewith (payable within 30 days of written demand); provided, however, Landlord shall have no obligation to change the scope of the Landlord Work (and any election to do so shall be in Landlord’s sole but reasonable discretion).

7.Security Deposit. The parties agree and acknowledge that Landlord currently holds a Security Deposit from Tenant in the amount of $49,707.14 pursuant to the Original Lease. Concurrently with Tenant’s execution of this Amendment, Tenant shall deposit with Landlord the sum of $2,919.66 to be added to the existing Security Deposit, such that the total required Security Deposit under the Lease shall be $52,626.80. Landlord shall continue to hold the Security Deposit (as increased pursuant to this Amendment) in accordance with the terms and conditions of the Original Lease (as amended hereby).

8.Parking. Effective as of the Expansion Date, the “Parking Pass Ratio” paragraph of the Summary shall be deleted in its entirety and replaced with the following:

“PARKING PASS RATIO”:    Subject to the terms and conditions of Article 28 of this Lease, Tenant shall have the right but not the obligation to rent from Landlord thirty-four (34) unreserved parking passes (based on a ratio of four (4) unreserved passes per 1,000 rentable square feet of the Premises), of which up to two (2) may be rented by Tenant for reserved passes (“Reserved Passes”), subject to availability, in mutually

agreeable locations, and the balance of the parking passes shall be for unreserved parking spaces in the Project’s parking structure.”

9.Option Term. For the avoidance of doubt, Tenant’s right to extend the Lease Term by the Option Term shall apply to the Expansion Term and must be exercised as to the entire Premises (i.e., the Existing Premises and the Expansion Premises) in accordance with the terms of Section 2.3 of the Initial Lease, and not either the Existing Premises or Expansion Premises individually.

10.Tenant Maintained Security. Tenant shall have the right to install appropriate security systems in the Premises, provided that such security systems (including system specifications and equipment) shall be subject to Landlord’s prior approval, which approval shall not be unreasonably withheld, conditioned or delayed. Except to the extent caused by the gross negligence or willful misconduct of Landlord or its agents, representatives, employees, consultants or contractors, Landlord will not be liable for the functionality, quality, action, or inaction of the Buildings’ access system or for any damage or injury to Tenant, its employees, invitees, or others, or their property, resulting from any failure, action, or inaction of the Buildings’ access system. Except to the extent caused by the negligence or willful misconduct of Landlord or its agents, representatives, employees, consultants or contractors, Tenant shall protect, indemnify, defend and hold Landlord, and its affiliates, officers, employees and agents, from and against all claims, costs, damages, fees, expenses (including without limitation attorneys’ fees) in connection with any failure or any damages caused by any Tenant installed security system. The foregoing indemnity, is in addition to, and shall be in no way deemed limited by any other indemnification obligations of Tenant set forth elsewhere in this Lease.

12.Severability. Any provision of this Amendment which shall prove to be invalid, void, or illegal shall in no way affect, impair or invalidate any other provision hereof and such other provisions shall remain in full force and effect.

(Landlord’s broker) (the foregoing, collectively, the ”Brokers”) and that they know of no other real estate broker or agent who is entitled to a commission in connection with this Amendment. Landlord shall pay the Brokers pursuant to the terms of a separate written commission agreement between Landlord and each Broker.
