PROMISSORY NOTE

PROMISE TO PAY. To repay Borrower's loan, AMPLITECH, INC. ("Borrower") promises to pay to BNB Bank ("Lender''), or order, in lawful money of the United States of America, the principal amount of Seven Hundred Fifty Thousand & 00/100 Dollars ($750,000.00) or so much as may be outstanding, together with interest on the unpaid outstanding principal balance of each advance. Interest shall be calculated from the date of each advance until repayment of each advance.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal plus all accrued unpaid interest on November 1, 2021. In addition, Borrower will pay regular monthly payments of all accrued unpaid interest due as of each payment date, beginning January 1, 2021, with all subsequent interest payments to be due on the same day of each month after that. Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid Interest; then to any late charges; then to any unpaid collection costs; then to any escrow or reserve account payments as required under any mortgage, deed of trust, or other security instrument or security agreement securing this Note; and then to principal. Borrower will pay Lender at Lender's address shown above or at such other place as Lender may designate in writing.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from time to lime based on changes in an independent index which is the WSJ Prime Rate Index (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 3.250% 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"), rounded up to the nearest 0.125 percent, adjusted if necessary for any minimum and maximum rate limitations described below, resulting in an initial rate of 5.500% 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 less than 5.500% per annum or more than the maximum rate allowed by applicable law.

INTEREST CALCULATION METHOD. Interest on this Note is computed on a 365/360 basis; that is, by applying the ratio of the interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding. All interest payable under this Note is computed using this method.

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: BNB Bank, 898 Veterans Memorial Highway, Suite 560 Hauppauge, NY 11788.

LATE CHARGE. If a payment is 10 days or more late, Borrower will be charged 5.000% of the regularly scheduled payment.

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 5.000 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.

DEFAULT. Each of the following shall constitute an event of default ("Event of Default") under this Note:

Payment Default. Borrower fails to make any payment when due under this Note.

Other Defaults. Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Note or in any of the related documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Borrower.

Borrower or any Grantor defaults under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Borrower's property or Borrower's ability to repay this Note or perform Borrower's obligations under this Note or any of the related documents.

However, this Event of Default shall not apply if there is a good faith dispute by Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount detem1ined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.
