2.    Interest Rate and Payments. Amounts outstanding under this Note will bear interest at a rate per annum which is at all times equal to the sum of the Daily LIBOR Rate (as defined below), plus the Applicable Margin (as such term is defined in Exhibit A attached hereto and made a part hereof). Accrued interest will be due and payable on the first day of each month, beginning with the payment due on January 1, 2021. The outstanding principal balance and any accrued but unpaid interest shall be due and payable on the Expiration Date.

3.    Certain Definitions. If the following terms are used in this Note, such terms shall have the meanings set forth below:

“Alternate Rate” shall mean the sum of (A) the Base Rate plus (B) the Applicable Margin (as such term is defined in Exhibit A attached hereto and made a part hereof).

“Base Rate” shall mean the higher of (A) the Prime Rate in effect on such day, and (B) the sum of the Overnight Bank Funding Rate in effect on such day plus 50 basis points (0.50%).

banks on such day; provided, however, if the Daily LIBOR Rate determined as provided above would be less than zero, then such rate shall be deemed to be zero. The rate of interest will be adjusted automatically as of each Business Day based on changes in the Daily LIBOR Rate without notice to the Borrower.

“Default Rate” shall mean the rate per annum (based on the actual number of days that principal is outstanding over a year of 360 days) equal to the lesser of (A) the sum of 3% plus the interest rate otherwise in effect from time to time under this Note, and (B) the Maximum Rate.

“Published Rate” shall mean the rate of interest published each Business Day in the Wall Street Journal under the caption “London Interbank Offered Rates” for a one month period (or, if no such rate is published therein for any reason, then the Published Rate shall be the eurodollar rate for a one month period as published in another publication selected by the Bank).

Regardless of any other provision of this Note or the other Loan Documents, if for any reason the effective interest rate should exceed the Maximum Rate, the effective interest rate shall be deemed reduced to, and shall be, the Maximum Rate, and (i) the amount which would be excessive interest shall be deemed applied to the reduction of the principal balance of this Note and not to the payment of interest, and (ii) if the loan evidenced by this Note has been or is thereby paid in full, the excess shall be returned to the party paying same, such application to the principal balance of this Note or the refunding of such excess to be a complete settlement and acquittance thereof.

6.    Alternate LIBOR Rate Provisions. If the Bank determines (which determination shall be final and conclusive) that, by reason of circumstances affecting the eurodollar market generally, deposits in dollars (in the applicable amounts) are not being offered to banks in the eurodollar market for the selected term, or adequate means do not exist for ascertaining the Daily LIBOR Rate, then the Bank shall give notice thereof to the Borrower. Thereafter, until the Bank notifies the Borrower that the circumstances giving rise to such suspension no longer exist, the interest rate for all amounts outstanding under this Note shall be equal to the Alternate Rate.

In addition, if, after the date of this Note, the Bank shall determine (which determination shall be final and conclusive) that any enactment, promulgation or adoption of or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by a governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Bank with any guideline, request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for the Bank to make or maintain or fund loans based on the Daily LIBOR Rate, the Bank shall notify the Borrower. Thereafter, until the Bank notifies the Borrower that the circumstances giving rise to such determination no longer apply, the interest rate on all amounts outstanding under this Note shall be the Alternate Rate.

The LIBOR Replacement Rider attached to this Note and incorporated herein by this reference provides a mechanism for determining an alternative rate of interest in the event that the London interbank offered rate is no longer available or in certain other circumstances. The Bank does not warrant or accept any responsibility for and shall not have any liability with respect to, the administration, submission or any other matter related to the London interbank offered rate or other rates in the definition of “LIBOR” or with respect to any alternative or successor rate thereto, or replacement rate therefor. To the extent that any term or provision of the LIBOR Replacement Rider is or may be inconsistent with any term or provision in the remainder of this Note or any other Loan Document, the terms and provisions of the LIBOR Replacement Rider shall control.

7.    Other Payment Terms. If any payment under this Note shall become due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall be included in computing interest in connection with such payment. The Borrower hereby authorizes the Bank to charge the Borrower’s deposit account at the Bank for any payment when due under this Note or any other Loan Document. Payments received will be applied to charges, fees and expenses (including attorneys’ fees), accrued interest and principal in any order the Bank may choose, in its sole discretion.

8.    Late Payments; Default Rate. If the Borrower fails to make any payment of principal, interest or other amount coming due pursuant to the provisions of this Note within 15 calendar days of the date due and payable, the Borrower also shall pay to the Bank a late charge equal to the lesser of 3% of the amount of such payment or $100.00 (the “Late Charge”). Such 15-day period shall not be construed in any way to extend the due date of any such payment. Upon maturity, whether by acceleration, demand or otherwise, and at the Bank’s option upon the occurrence of any Event of Default (as hereinafter defined) and during the continuance thereof, amounts outstanding under this Note shall bear interest at the Default Rate. The Default Rate shall continue to apply whether or not judgment shall be entered on this Note. Both the Late Charge and the Default Rate are imposed as liquidated damages for the purpose of defraying the Bank’s expenses incident to the handling of delinquent payments, but are in addition to, and not in lieu of, the Bank’s exercise of any rights and remedies hereunder, under the other Loan Documents or under applicable law, and any fees and expenses of any agents or attorneys which the Bank may employ. In addition, the Default Rate reflects the increased credit risk to the Bank of carrying a loan that is in default. The Borrower agrees that the Late Charge and Default Rate are reasonable forecasts of just compensation for anticipated and actual harm incurred by the Bank, and that the actual harm incurred by the Bank cannot be estimated with certainty and without difficulty.

9.    Prepayment. The indebtedness evidenced by this Note may be prepaid in whole or in part at any time without penalty or premium.

10.    Increased Costs; Yield Protection. On written demand, together with written evidence of the justification therefor, the Borrower agrees to pay the Bank all direct costs incurred, any losses suffered or payments made by the Bank as a result of any Change in Law (hereinafter defined), imposing any reserve, deposit, allocation of capital or similar requirement (including without limitation, Regulation D of the Board of Governors of the Federal Reserve System) on the Bank, its holding company or any of their respective assets relative to the Facility. “Change in Law” means the occurrence, after the date of this Note, of any of the following: (a) the adoption or taking effect of any law, rule, regulation or treaty, (b) any change in any law, rule, regulation or treaty or in the administration, interpretation, implementation or application thereof by any governmental authority or (c) the making or issuance of any request, rule, guideline or directive (whether or not having the force of law) by any governmental authority; provided that notwithstanding anything herein to the contrary, (x) the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, guidelines or directives thereunder or issued in connection therewith and (y) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III, shall in each case be deemed to be a “Change in Law”, regardless of the date enacted, adopted or issued.

13.    Right of Setoff. In addition to all liens upon and rights of setoff against the Borrower’s money, securities or other property given to the Bank by law, the Bank shall have, with respect to the Borrower’s obligations to the Bank under this Note and to the extent permitted by law, a contractual possessory security interest in and a contractual right of setoff against, and the Borrower hereby grants the Bank a security interest in, and hereby assigns, conveys, delivers, pledges and transfers to the Bank, all of the Borrower’s right, title and interest in and to, all of the Borrower’s deposits, moneys, securities and other property now or hereafter in the possession of or on deposit with, or in transit to, the Bank or any other direct or indirect subsidiary of The PNC Financial Services Group, Inc., whether held in a general or special account or deposit, whether held jointly with someone else, or whether held for safekeeping or otherwise, excluding, however, all IRA, Keogh, and trust accounts.

    As used herein, the term “Applicable Margin” shall mean, beginning on the date hereof, two and one quarter percent (2.25%) per annum and, thereafter, the Applicable Margin shall be subject to adjustment as of the end of Borrower’s fiscal quarter ending after the Effective Date, based on the Net Leverage Ratio as of such quarter end and for each successive quarter thereafter. Any increase or decrease in the Applicable Margin computed as of a quarter end shall be effective on the date on which the Compliance Certificate evidencing such computation is due to be delivered under Section 6.2(d) of the Loan Agreement. For the avoidance of doubt, if the Net Leverage Ratio, measured as of the end of each fiscal quarter, is as described below, the Applicable Margin shall be the Applicable Margin appearing opposite the corresponding Net Leverage Ratio:

Bank shall determine whether any adjustment to the Applicable Margin is to be made quarterly, based on the Compliance Certificate delivered to Bank pursuant to the Loan Agreement; provided, however, that if such Compliance Certificate is not timely delivered to Bank, then, at the option of Bank, an adjustment to the Applicable Margin shall be made based on an assumed delivery of said Compliance Certificate reflecting a Net Leverage Ratio which is greater than 1.25 to 1.00; provided, further, at the option of the Bank, on and after receipt of a notice that an Event of Default has occurred, the Default Rate may then apply as of the date of such Event of Default (as reasonably determined by Bank) and shall continue to apply to but excluding the date on which such Event of Default shall cease to be continuing (and thereafter, in each case, the Applicable Margin otherwise determined in accordance with this Exhibit A shall apply). Each such adjustment shall apply to all Advances then existing and any made during the period for which such adjustment becomes effective.
