Promissory Note delivered to UMB Bank, n.a., dated June 1, 2023

UNCONDITIONALLY CANCELABLE. Notwithstanding anything to the contrary in this Note or any other agreement or understanding involving Borrower and Lender, (1) the line of credit evidenced by this Note and all other commitments, facilities, and accommodations under or related to this Note are unconditionally cancelable by Lender, and (2) Lender may, at any time, with or without cause, terminate or refuse to extend credit under the line of credit evidenced by this Note or any other commitment, facility, or accommodation under or related to this Note (to the fullest extent permitted under applicable law). This paragraph applies to any letter-of-credit facility or other obligation of Lender to issue a letter of credit for the benefit of Borrower in connection with this Note (if and to the extent that such a facility or other obligation separately exists), but once issued, whether a letter of credit is itself conditionally or unconditionally cancelable is governed by other provisions of contract or other applicable law.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from time to time based on changes in an independent index which is the Federal Funds Effective Rate. "Federal Funds Effective Rate" means, for any day, the rate per annum equal to the weighted average of the rates on overnight federal funds transactions with members of the Federal Reserve System arranged by federal funds brokers on such day, as published by the Federal Reserve Bank of New York on the Business Day next succeeding such day, provided, that (a), if such day is not a Business Day, the Federal Funds Rate for such day shall be such rate on such transactions on the immediately preceding Business Day as so published on the next succeeding Business Day and (b) if no such rate is so published on such next succeeding Business Day, the Federal Funds Rate for such day shall be the average rate charged to the Lender on such day on such transactions as determined by the Lender. (the "Index"). The Index is not necessarily the lowest rate charged by Lender on its loans. Lender will tell Borrower the current Index rate upon Borrower's request. The interest rate change will not occur more often than each day. Borrower understands that Lender may make loans based on other rates as well. The Index currently is 4.850% per annum. Interest on the unpaid principal balance of this Note will be calculated as described in the "INTEREST CALCULATION METHOD" paragraph using a rate of 1.000 percentage point over the Index (the "Margin"), resulting in an initial rate of 5.850% per annum based on a year of 360 days. If Lender determines, in its sole discretion, that the Index has become unavailable or unreliable, either temporarily, indefinitely, or permanently, during the term of this Note, Lender may amend this Note by designating a substantially similar substitute index. Lender may also amend and adjust the Margin to accompany the substitute index. The change to the Margin may be a positive or negative value, or zero. In making these amendments, Lender may take into consideration any then-prevailing market convention for selecting a substitute index and margin for the specific Index that is unavailable or unreliable. Such an amendment to the terms of this Note will become effective and bind Borrower 10 business days after Lender gives written notice to Borrower without any action or consent of the Borrower. NOTICE: Under no circumstances will the interest rate on this Note be more than the maximum rate allowed by applicable law.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower's obligation to continue to make payments of accrued unpaid interest. Rather, early payments will reduce the principal balance due. Borrower agrees not to send Lender payments marked "paid in full", "without recourse", or similar language. If Borrower sends such a payment, Lender may accept it without losing any of Lender's rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes "payment in full" of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: UMB Bank, n.a., Attn: Loan Accounting, PO Box 419226 - MS #1170203 Kansas City, MO 64141-6226.

LATE CHARGE. If a regularly scheduled interest payment is more than 29 days late, Borrower will be charged 10.000% of the unpaid portion of the regularly scheduled payment or $50.00, whichever is less. If Lender demands payment of this loan, and Borrower does not pay the loan in full within 29 days after Lender's demand, Borrower also will be charged either 10.000% of the unpaid portion of the sum of the unpaid principal plus accrued unpaid interest or $50.00, whichever is less.

INTEREST AFTER DEFAULT. Upon default, including failure to pay upon final maturity, the interest rate on this Note shall be increased by adding an additional 2.000 percentage point margin ("Default Rate Margin"). The Default Rate Margin shall also apply to each succeeding interest rate change that would have applied had there been no default. However, in no event will the interest rate exceed the maximum interest rate limitations under applicable law.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal balance under this Note and all accrued unpaid interest immediately due, and then Borrower will pay that amount.

ATTORNEYS' FEES; EXPENSES. Lender may hire or pay someone else to help collect this Note if Borrower does not pay. Borrower will pay Lender that amount. This includes, subject to any limits under applicable law, Lender's attorneys' fees and Lender's legal expenses whether or not there is a lawsuit, including attorneys' fees and expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), and appeals. If not prohibited by applicable law, Borrower also will pay any court costs, in addition to all other sums provided by law.

CHOICE OF VENUE. If there is a lawsuit, Borrower agrees upon Lender's request to submit to the jurisdiction of the courts of Jackson County, State of Missouri.

DISHONORED ITEM FEE. Borrower will pay a fee to Lender of $25.00 if Borrower makes a payment on Borrower's loan and the check or preauthorized charge with which Borrower pays is later dishonored.

RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a right of setoff in all Borrower's accounts with Lender (whether checking, savings, or some other account). This includes all accounts Borrower holds jointly with someone else and all accounts Borrower may open in the future. However, this does not include any IRA or Keogh accounts, or any trust accounts for which setoff would be prohibited by law. Borrower authorizes Lender, to the extent permitted by applicable law, to charge or setoff all sums owing on the debt against any and all such accounts, and, at Lender's option, to administratively freeze all such accounts to allow Lender to protect Lender's charge and setoff rights provided in this paragraph.

COLLATERAL. This loan is unsecured.

LINE OF CREDIT. This Note evidences a revolving line of credit. Advances under this Note, as well as directions for payment from Borrower's accounts, may be requested orally or in writing by Borrower or by an authorized person. Lender may, but need not, require that all oral requests be confirmed in writing. Borrower agrees to be liable for all sums either: (A) advanced in accordance with the instructions of an authorized person or (B) credited to any of Borrower's accounts with Lender. The unpaid principal balance owing on this Note at any time may be evidenced by endorsements on this Note or by Lender's internal records, including daily computer print-outs. Lender will have no obligation to advance funds under this Note if: (A) Borrower or any guarantor is in default under the terms of this Note or any agreement that Borrower or any guarantor has with Lender, including any agreement made in connection with the signing of this Note; (B) Borrower or any guarantor ceases doing business or is insolvent; (C) any guarantor seeks, claims or otherwise attempts to limit, modify or revoke such guarantor's guarantee of this Note or any other loan with Lender; or (D) Borrower has applied funds provided pursuant to this Note for purposes other than those authorized by Lender.

ADDITIONAL TERMS. Borrower shall not a) voluntarily transfer any assets into trust or, b) if already owned in trust, shall not voluntarily transfer title to such trust assets to any other person or entity, without giving Lender at least 30 days prior written notice thereof.

JURY WAIVER. BORROWER HEREBY KNOWINGLY, INTENTIONALLY, VOLUNTARILY AND IRREVOCABLY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM OF ANY KIND, REGARDLESS OF THE LEGAL THEORY UPON WHICH IT IS BASED, ARISING OUT OF, PERTAINING TO OR OTHERWISE RELATING TO THIS AGREEMENT, THE LOAN, ANY OF THE LOAN DOCUMENTS OR LENDER’S CONDUCT IN RESPECT OF ANY OF THE FOREGOING.

PRIOR NOTE. Promissory Note dated January 11, 2019, executed by Borrower to Lender in the amount of $25,000,000.00 and as subsequently modified, renewed or extended.

SUCCESSOR INTERESTS. The terms of this Note shall be binding upon Borrower, and upon Borrower's heirs, personal representatives, successors and assigns, and shall inure to the benefit of Lender and its successors and assigns.

ELECTRONIC RECORDS AND SIGNATURES/TRANSFERABLE RECORD. Borrower consents to the use of electronic records and signatures (when Lender offers them) in connection with this Note and all related documents and information. This consent is provided in accordance with the federal Electronic Signatures in Global and National Commerce Act or any other applicable law addressing the use of electronic records and signatures (including the Uniform Electronic Transactions Act, as adopted by the state whose law governs this Note (collectively, the “Electronic Signature Laws”)). Lender may store this Note and all related documents and information as electronic records (including by imaging or converting any original paper documents into electronic records) and may destroy any original paper documents after doing so. All electronic records and signatures used in connection with this Note and all related documents and information will have the same legal effect, validity and enforceability as original paper documents and original manual signatures. If Borrower uses an electronic signature to sign an electronic record of this Note, Borrower expressly agrees that such electronically signed electronic record of this Note is a transferrable record within the meaning of, and for all purposes under, the Electronic Signature Laws.

GENERAL PROVISIONS. This Note is payable on demand. The inclusion of specific default provisions or rights of Lender shall not preclude Lender's right to declare payment of this Note on its demand. If any part of this Note cannot be enforced, this fact will not affect the rest of the Note. Lender may delay or forgo enforcing any of its rights or remedies under this Note without losing them. Borrower and any other person who signs, guarantees or endorses this Note, to the extent allowed by law, waive presentment, demand for payment, and notice of dishonor. Upon any change in the terms of this Note, and unless otherwise expressly stated in writing, no party who signs this Note, whether as maker, guarantor, accommodation maker or endorser, shall be released from liability. All such parties agree that Lender may renew or extend (repeatedly and for any length of time) this loan or release any party or guarantor or collateral; or impair, fail to realize upon or perfect Lender's security interest in the collateral; and take any other action deemed necessary by Lender without the consent of or notice to anyone. All such parties also agree that Lender may modify this loan without the consent of or notice to anyone other than the party with whom the modification is made. The obligations under this Note are joint and several.
