Pursuant to the Credit Agreement, the Company may, from time to time, increase the size of the revolving credit facility or enter into one or more tranches of term loans in minimum increments of USD 25 million if there is no event of default and the Company is in compliance with certain financial covenants.

Loans under the Credit Agreement bear interest as follows: (i) each loan (other than Swing Line Loans) shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the Applicable Rate, as determined in accordance with the performance pricing grid set forth in the Credit Agreement, plus one of the following indexes: (a) Term SOFR (in the case of U.S. dollar-denominated loans), (b) SONIA plus a credit spread (in the case of Pound-denominated loans), (c) EURIBOR (in the case of Euro-denominated loans), (d) SARON plus a credit spread (in the case of Swiss Franc-denominated loans), (e) TIBOR (in the case of Yen-denominated loans) or (f) the Base Rate; and (ii) each Swingline Loan shall bear interest at a rate per annum equal to Applicable Rate plus the Base Rate. The Company shall pay to Bank of America, N.A., for the account of the Lenders, a commitment fee equal to the Applicable Rate multiplied by the actual daily amount by which the Aggregate Revolving Commitments exceed the sum of (i) the Outstanding Amount of the Revolving Loans and (ii) the Outstanding Amount of the L/C Obligations. The commitment fee shall be due and payable in arrears on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the Closing Date, and ending on the Maturity Date.

Revolving Loans may be borrowed, repaid and reborrowed until the Maturity Date, at which time all amounts borrowed must be repaid. Accrued interest on the loans is payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified in the Credit Agreement. Subject to certain conditions, (i) the Company may terminate or reduce the Aggregate Revolving Commitments in whole or in part, and (ii) a Borrower may prepay the Revolving Loans at any time, without premium or penalty.

Among other terms and conditions applicable to the Incremental Term Loans (made pursuant to the term loan expansion option summarized above), the Incremental Term Loans (1) shall not mature earlier than the Maturity Date (but may have amortization prior to such date) (except as otherwise provided in the Credit Agreement with respect to customary bridge Indebtedness), (2) the terms and conditions applicable to any tranche of Incremental Term Loans shall otherwise be on terms not materially more onerous, taken as a whole, to the Company than the Revolving Loans and any other Incremental Term Loans, and (3) the Incremental Terms Loans may be priced differently than the Revolving Loans. The Credit Agreement contains customary representations and warranties. The Credit Agreement also contains customary affirmative and negative covenants, including covenants that limit or restrict the Company's ability to, among other things, grant liens, make investments, incur indebtedness (at the Company or subsidiary level), merge or consolidate and make certain payments, in each case subject to customary exceptions for a credit facility of this size and type.

The Company is also required to maintain compliance with a consolidated interest coverage ratio and a consolidated net leverage ratio. The Credit Agreement includes customary events of default that include, among other things, payment and non-payment defaults, covenant defaults, inaccuracy of representations and warranties, cross-default to material indebtedness, bankruptcy and insolvency defaults, material judgment defaults, ERISA defaults and a change of control default. The occurrence of an event of default could result in the acceleration of the obligations under the Credit Agreement.

In the ordinary course of their respective businesses, certain of the Lenders and the other parties to the Credit Agreement and their respective affiliates are, and may become in the future, customers of the Company and have engaged, or may in the future engage, in commercial banking, investment banking, financial advisory or other services with the Company for which they have in the past and/or may in the future receive customary compensation and expense reimbursement.
