In addition, if a Lease is executed, you agree that you will have earned no commission if the Lease contains any conditions to its effectiveness or any rights exist on the part of the Tenant to terminate the Lease prior to the commencement
of the term, until all conditions are satisfied or until the time to exercise such options has expired, in the event that all conditions are not satisfied or any option is exercised so that the Lease is terminated prior to the commencement of the
term, then no commission or other compensation shall be payable to you. Notwithstanding the extent to which negotiations may heretofore or hereafter commence or continue, you agree that no commission or other compensation shall be payable to you if
any of the conditions of the foregoing paragraph are not fulfilled for any reason whatsoever including, without limitation, Tenants or Landlords arbitrary refusal or inability to execute and unconditionally deliver the Lease, and in such
an event you agree that you shall not have any right to and shall not assert any claim against the Landlord for a commission other compensation rendered in connection with the Lease or otherwise.



In the event that a commission (Commission) is payable to you, Landlord agrees to

rental abatement period, (ii) any increment of rental attributable to the amortization of any tenant finish costs which are the responsibility of Tenant but are financed by or through Landlord, (iii) any escalation of such rental measured by, based
on, or indexed to inflation, (iv) any increase above the base year or expense stop to be paid by Tenant as reimbursements for costs and expenses incurred or arising out of the ownership,



11



---

operation, or use of the Building, including, but not limited to, costs and expenses of maintenance, taxes, cleaning,
repairs, insurance, utilities, security services, and labor with respect to the Building (i.e. escalations), and (vi) the amount of any costs and expenses incurred or to be incurred by Landlord in connection with Landlords assumptions of,
Tenants obligations under any existing lease or Landlords indemnification of Tenant for any of Tenants obligations under any existing lease, or any other reimbursements, termination payments or other takeover obligations to be paid
or assumed by Landlord with respect to, Tenants obligation under any existing lease.



Subject to the foregoing provisions of this Agreement, the Commission shall be paid in the following installments.



(i) One half (1/2)of the Commission shall be paid within thirty (30) days after receipt by the Landlord of a fully executed lease agreement and an
invoice from Broker, with respect to the Lease, such invoice to be delivered to the Landlord after the Commission is earned as previously described herein, and



(ii) The remaining one half (1/2) of the Commission shall be paid within thirty (30) days after receipt by Landlord of a subsequent invoice from
Broker, with respect to the Lease, such subsequent invoice to be delivered to the Landlord after Tenant commences paying rent pursuant to the Lease or occupies the initial increment of demised space, whichever occurs first.



If the lease provides for any renewal options, then, upon the exercise of such options by
Tenant (and the execution of any necessary lease or addendum), if Broker is the only authorized broker representing Tenant in such regard, Broker shall be entitled to an additional Commission equal to four and one-half percent (4.5%) of the gross
base rental, utilizing the applicable term of said elected renewal option in determination of same.



Subject to the foregoing provisions of this Agreement the renewal option Commission shall be paid within thirty (30) days after (i) receipt by Landlord of a fully executed renewal agreement and, (ii) receipt by
Landlord of an invoice from Broker with respect to the renewal.



If the Lease
provides for any expansion options or rights of first refusal, then, upon the exercise of such rights or options by Tenant (and the execution of any necessary lease or addendum), if Broker is the only authorized broker representing Tenant in such
regard, Broker shall be entitled to an additional Commission equal to four and one-half percent (4.5%) of the gross base rental, utilizing the applicable term of said elected expansion option or right of first refusal in the determination of same.



12

Subject to the foregoing provisions of this Agreement the expansion option or right of first refusal commission shall be
paid in the following installments:



(i) One half (1/2) of the
Commission shall be paid within thirty (30) days after receipt by the Landlord of a fully executed amendment with respect to the expansion option or right of first refusal and an invoice, to be delivered to the Landlord after the Commission is
earned as previously described herein, and



ii) The remaining
one half (1/2) of the Commission shall be paid within thirty (30) days after receipt by Landlord of a subsequent invoice from Broker with respect to the expansion option or right of first refusal, such subsequent invoice to be delivered after Tenant
actually takes occupancy of the premises covered by the expansion option or right of first refusal, accepts the condition of and commences rental payments upon the premises covered by the expansion option or right of first refusal, whichever occurs
first.

existence or exercise of any renewal options, expansion options or rights of first refusal, will any Commission be payable for any gross base rental or other charges payable by Tenant for any year of the Lease term subsequent to the tenth (10th)
lease year of the term of the Lease.



Notwithstanding the above, if there shall
be any other claim or claims for a Commission or other compensations by a claimant purporting to represent Tenant with respect to the Lease, any renewal or extension thereof, or for any expansion or exercise of a right of first refusal, Landlord
shall not be required to pay Broker any Commission until and unless all such parties claiming a Commission or other compensation release Landlord from such, claims or a court orders Landlord to pay the commission or other compensation. If Landlord
is in doubt as to whom a Commission or other compensation is payable, Landlord shall have the right to pay the Commission to a court of competent jurisdiction and in such event Landlord shall be released from all liability.

be relieved of all obligation hereunder provided, however, Landlord shall make reasonable efforts to cause: said thirty party to assume Landlords obligations hereunder. In the event of a sale of the Building by Landlord after the full
execution of the Lease but prior to the payment of the first and/or second halves of the commission for the initial term of the Lease, Landlord shall remain obligated to pay such commission.



This agreement shall not be binding unless executed by both parties. When executed by both
parties, this agreement shall be binding upon and inure to the benefit of the parties hereto and their respective legal representatives, successors and assigns. The provisions of this Agreement supersede all previous oral and written understandings
and agreements by the parties.

entire agreement concerning the matters discussed herein, please sign and return the enclosed copies.



Sincerely,

attached hereto and made a part hereof for all purposes. Tenant shall pay the Actual Cost (defined below)
of all Tenant Finish Work in excess of $7.00 per rentable square foot, for a total of $134,526.00 (the Work Allowance). The Work Allowance includes the cost of preparing the Construction Documents.



The term Actual Cost means the cost of all labor and materials
and all hard and soft costs, together with the Building Service Fee of three (3%) of all hard costs, incurred by Landlord in performing the Tenant Finish Work or the Additional Work (defined below), as applicable.



If prior to commencement of the Tenant Finish Work Landlord determines,
based on construction bids received by Landlord, that the Actual Cost of the Tenant Finish Work will exceed the Work Allowance, Tenant shall pay the excess to Landlord. Landlord is not obligated to commence the Tenant Finish Work until it receives
the excess payment from Tenant.



If during construction the
Actual Cost of the Tenant Finish Work exceeds the Work Allowance and all amounts previously paid by Tenant to Landlord prior to the commencement of construction, Landlord shall submit interim statements covering any excess costs incurred by Landlord
under this Paragraph and Tenant shall pay the amount of the excess costs to Landlord. If following completion of the Tenant Finish Work and any Additional Work, the Actual Cost of all such work is less than the Work Allowance, Tenant shall be
permitted to utilize the remaining balance of the Work Allowance towards the Actual Cost of additional improvements to the Leased Premises to be performed in accordance with terms set forth in Paragraph 11 .A. of the Lease Agreement (the Final
Work); provided, however, in the event that any and all such Final Work is not completed on or before that date which is one (1) year following the date of this Amendment (time being of the essence), Tenants rights to utilize any
remaining balance of the Work Allowance shall automatically terminate and be null and void and of no further force or effect, and Tenant shall have forfeited same.



|3. | ADDITIONAL WORK.If Landlord performs, at Tenants request and upon submission by Tenant and approval by Landlord of necessary plans and specifications (as
approved, the Additional Work Plans), any work over and above the Tenant Finish Work (Additional Work), including any Additional Work approved by change order or work order, the Additional Work is at Tenants expense,
regardless of any remaining balance of the Work Allowance. Landlord is not obligated to perform any Additional Work until Tenant pays Landlord the Actual Cost of the Additional Work, as estimated by Landlord. If the Actual Cost of the Additional
Work exceeds the estimated amount paid by Tenant, Tenant shall pay the excess to Landlord.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



The Additional Work is not part of the Tenant Finish Work. If Landlord agrees to perform any Additional Work, Landlord shall request that its contractor
estimate the additional amount of time that will be added to the completion of the Tenant Finish Work because of the Additional Work (the Additional Work Period).
