The Note shall (a) be dated as of the date hereof; (b) be stated to be due on December 30, 2021 (the "Maturity Date"); (c) bear interest (at the applicable interest rate provided herein below) from the date hereof on the unpaid principal amount thereof, with quarterly payments of interest only, based on the outstanding principal balance of the Note, payable beginning on September 30, 2020 and on the thirtieth (30^th) day of each of December, March, June and September during the term hereof; and (d) all unpaid principal and interest payable in full upon the Maturity Date.

B.‌Interest Rate/One-Month LIBOR Base Rate. Interest shall accrue on the unpaid principal balance of the Note at a variable per annum rate equal to the One Month LIBOR Base Rate (as hereinafter defined), plus a margin of 350 basis points (or 3.50%) (the "Interest Rate"), provided that the Interest Rate shall never be less than 4.0% or exceed the maximum rate permitted by law. The Interest Rate may change as often as monthly. The interest rate hereunder shall be adjusted monthly in accordance with fluctuations in the One Month LIBOR Base Rate. The effective date of any rate change will be the last business day (as defined below) of each month.

For purposes hereof, "One Month LIBOR Base Rate " means the percentage rate of interest at which one (1) month deposits in United States dollars in an amount equal to the principal balance of the Loan on the effective date of this Agreement (or the next higher amount for which quotes are available in the London Interbank Market) are offered to major banks in the London Interbank Market as published in the Wall Street Journal on the first Business Day of each month. Such One Month LIBOR Base Rate is established by CENTERSTATE BANK as an index or base rate and shall be the lowest rate of interest offered by the Lender.

The LIBOR Base Rate shall be the "offered to" rate reported by a reliable source for LIBOR quotes selected by the Lender in its sole discretion. If two or more applicable "offered to" rates are reported by that source, the LIBOR Base Rate shall be the arithmetic mean of such rates. "Business day" means any day on which dealings in deposits in United States dollars are conducted in the London Interbank Market other than Saturday, Sunday, or a day on which national banks are authorized or required by law to be closed in the city where the Lender's office, as identified above, is located, and any performance which would otherwise be required on a day other than a business day shall be timely performed in such instance, if performed on the next succeeding business day. Notwithstanding such timely performance, interest shall continue to accrue hereunder until such payment or performance has been made.

All interest accruing under this Note shall be computed on a 360 day basis (i.e., interest for each day during which the principal amount of the Note is outstanding shall be computed at the Interest Rate divided by 360, for the actual number of days elapsed) and the applicable Interest Rate shall not exceed the maximum rate of interest permitted by law.

If a payment of principal and/or interest is more than ten (10) days late, Lender shall charge Borrower charged a late fee of 5% of the payment amount due. Any such delinquent payments shall be applied, in the sole Lender's discretion, first to any late charges and interest which have accrued. Upon default, Lender, at its option, may increase the interest rate on the Note up to the lesser of 18% per annum or the maximum rate permitted by applicable law.

B.‌Replacement LIBOR Rate.

(1)‌Trigger Events. Notwithstanding anything to the contrary in this Agreement or any other Loan Documents, if: (a) Lender determines that adequate and reasonable means do not exist for ascertaining the One Month LIBOR Base Rate for any interest period hereunder, including, without limitation, because the One Month LIBOR Rate is not available or published on a current basis and such circumstances are unlikely to be temporary, or (b) the administrator of the One Month LIBOR Base Rate or a governmental authority having jurisdiction over Lender has made a public statement identifying a specific date after which the One Month LIBOR Base Rate shall no longer be made available, or used for determining the interest rate of U.S. Dollar denominated loans, or (c) Lender determines (which determination shall be conclusive absent manifest error) that similar U.S. dollar denominated credit facilities (syndicated or otherwise) among national and/or regional banks active in leading and participating in such facilities currently being executed, or that include language similar to that contained in this Section, are being executed or amended (as applicable) to incorporate or adopt a new benchmark interest rate to replace the One Month LIBOR Base Rate, or (d) Lender has determined, in its sole but reasonable discretion, that the One Month LIBOR Base Rate as determined by Lender will not adequately and fairly reflect the cost to Lender of making or funding the Loan and such circumstances are unlikely to be temporary, (in each case, a "Trigger Event") then, reasonably promptly after such determination by Lender or receipt by Lender of such notice, or the date of such public statement, as applicable, Lender shall give Borrower written notice thereof, and Lender and Borrower may amend this Agreement to replace the One Month LIBOR Base Rate with an alternate benchmark rate (any such proposed rate, which may include SOFR, Term SOFR and/or Compounded SOFR, a "LIBOR Successor Rate"). Any such amendment, together with any proposed LIBOR Successor Rate Conforming Changes (a "LIBOR Successor Amendment") shall become effective at 5:00 p.m. (Eastern time) on the fifth (5th) Business Day after Lender shall have posted such proposed amendment to Borrower (the "LIBOR Successor Replacement Date") without any further action or consent of any party to this Agreement Any LIBOR Successor Rate that is implemented in accordance with this Section shall in any event be applied in a manner consistent with market practice (or, if the Lender determines that adoption of any portion of such market practice is not administratively feasible or that no market practice for the administration of such LIBOR Successor Rate exists, in such other manner of administration as the Lender reasonably determines, after consultation with Borrower).

(2)‌No LIBOR Loans. If no LIBOR Successor Rate can reasonably be determined after the occurrence of a Triggering Event, the obligation of the Lender to maintain the Loan at the One Month LIBOR Base Rate shall be suspended (to the extent of the affected interest periods). Until a LIBOR Successor Rate has been determined pursuant to Section II 8(1) above, the Loan shall bear interest at the last calculated Interest Rate.

(3)‌LIBOR Successor Conforming Changes. In connection with the implementation of a LIBOR Successor Rate, the Lender will have the right to make LIBOR Successor Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such LIBOR Successor Conforming Changes will become effective without any further action or consent of any other party to this Agreement.

(4)‌Never Less Than Zero. Notwithstanding anything else herein, any definition of LIBOR Successor Rate shall provide that in no event shall such LIBOR Successor Rate be less than 0% (the "Index Floor") for purposes of this Agreement; provided, however, if Borrower has entered into an interest rate swap transaction with Lender for purposes of hedging the interest rate on any Note, then no Index Floor shall be applicable during the period(s) such swap transaction is in effect.

(5)‌No Liability. No failure of, or delay in, responding to any notice delivered to Lender under this Section ll(B) shall result in any breach by, or liability to, Lender in respect of this Agreement.
