(b)Upon
the occurrence of any Event of Default hereunder or under any other Loan Document, then in any such event the holder hereof may,
at its option, (i) declare the entire unpaid balance of principal and accrued interest of the Obligation to be immediately
due and payable without presentment or notice of any kind which Maker waives pursuant to Section 7 herein,
(ii) reduce any claim to judgment, and/or (iii) pursue and enforce any of Payee’s rights and remedies available pursuant

9.          Usury
Laws. Regardless of any provisions contained in this Note, the Payee shall never be deemed to have contracted for or be entitled
to receive, collect, or apply as interest on the Note, any amount in excess of the Maximum Rate, and, in the event Payee ever
receives, collects, or applies as interest any such excess, such amount which would be excessive interest shall be applied to
the reduction of the unpaid principal balance of this Note, and, if the principal balance of this Note is paid in full, then any
remaining excess shall forthwith be paid to Maker. In determining whether or not the interest paid or payable under any specific
contingency exceeds the highest lawful rate, Maker and Payee shall, to the maximum extent permitted under applicable law, (a)
characterize any non-principal payment (other than payments which are expressly designated as interest payments hereunder)
as an expense, fee, or premium, rather than as interest, (b) exclude voluntary prepayments and the effect thereof, and (c) spread
the total amount of interest throughout the entire contemplated term of this Note so that the interest rate is uniform throughout
such term.


 


10.          Costs.
The loan evidenced by this Note shall be closed without expense to Payee, it being understood and agreed that all expenses necessary
and usual to a transaction of this kind shall be paid by Maker, such expenses to include but not to be limited to: (a) recording
fees and (b) reasonable attorneys’ fees arising in connection with the negotiation and preparation of this Note and
all documents to be executed in connection with this Note. If this Note is placed in the hands of an attorney for collection,
or if it is collected through any legal proceeding at law or in equity, or in bankruptcy, receivership or other court proceedings,
Maker agrees to pay all costs of collection, including, but not limited to, court costs and reasonable attorneys' fees, including
all costs of appeal.


 


11.          Notices.
Any notice that may be given by either Maker or Payee shall be in writing and shall be deemed given upon the earlier of the
time of receipt thereof by the person entitled to receive such notice, or if mailed by registered or certified mail or with a
recognized overnight mail courier upon two (2) days after deposit with the United States Post Office or one (1) day

ANY OF THIS NOTE OR THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, OR THE ACTIONS OF PAYEE IN THE
NEGOTIATION, ADMINISTRATION, OR ENFORCEMENT THEREOF. THIS WAIVER OF RIGHT TO TRIAL BY JURY IS GIVEN KNOWINGLY AND VOLUNTARILY

WAIVER BY MAKER.


 


16.          ENTIRETY.
