On December 20, 2019 (the "Closing Date"), the Company amended and restated its Credit Agreement (the "A&R Credit Agreement"), dated December 7, 2016, as amended on December 20, 2018, with Bank of America, N.A. ("Bank of America"), as administrative agent, swingline lender and letter of credit issuer, the other lenders party thereto, and certain of the Company's subsidiaries as guarantors. Pursuant to the A&R Credit Agreement, the lenders provided term commitments of $150.0 million in the aggregate in a single draw on the Closing Date to fund the acquisition of QSI and various costs and expenses relating thereto and revolving commitments totaling $215.0 million in the aggregate. The revolving commitment is available through December 20, 2024 (the "Maturity Date"), at which time the term commitments and revolving commitments will be due and payable in full. An aggregate amount of $320.5 million was drawn under the A&R Credit Agreement on the Closing Date to fund the QSI acquisition and repay previously existing borrowings. The Senior Credit Facility is secured by a first priority lien on substantially all of the assets of the Company. The A&R Credit Agreement also includes an accordion feature permitting the Company to request an increase in either the term facility or the revolver facility under the A&R Credit Agreement by an additional amount of up to $100.0 million in the aggregate.

Borrowings under the A&R Credit Agreement bear interest at variable rates described below, which are, at the Company's option, tied to a Eurocurrency rate equal to LIBOR (London Interbank Offered Rate) plus an applicable margin or a base rate denominated in U.S. dollars. Interest rates are subject to change based on the Company's consolidated leverage ratio. The consolidated leverage ratio is the ratio of our pro forma consolidated funded indebtedness to the Company's pro forma consolidated EBITDA for the most recently completed measurement period.

The A&R Credit Agreement contains covenants that may have the effect of limiting the ability of the Company and its subsidiaries to, among other things, merge with or acquire other entities, enter into a transaction resulting in a Change in Control, create certain new liens, incur certain additional indebtedness, engage in certain transactions with affiliates, or engage in new lines of business or sell a substantial part of their assets. The A&R Credit Agreement also contains financial covenants that requires the Company to maintain a consolidated fixed charge coverage ratio of no less than 1.20 to 1.00 as of the end of any measurement period. In addition, prior to the Amendment Closing Date referred to below, the Company was required to maintain a consolidated leverage ratio as described below:



Measurement Period Ending	Maximum Consolidated Leverage Ratio
Closing Date through June 30, 2020	4.25 to 1.00
July 1, 2020 through September 30, 2020	4.00 to 1.00
October 1, 2020 through December 31, 2020	3.75 to 1.00
January 1, 2021 and thereafter	3.50 to 1.00

The A&R Credit Agreement also contains customary events of default, including (but not limited to) a default in the payment of principal or, following an applicable grace period, interest, breaches of the Company's covenants or warranties under the A&R Credit Agreement, payment default or acceleration of certain indebtedness of the Company or any subsidiary, certain events of bankruptcy, insolvency or liquidation involving the Company or any subsidiaries, certain judgments or uninsured losses, changes in control and certain liabilities related to ERISA based plans.

The A&R Credit Agreement limits the payment of cash dividends (together with certain other payments that would constitute a "Restricted Payment" within the meaning of the A&R Credit Agreement and generally including dividends, stock repurchases and certain other payments in respect to warrants, options, and other rights to acquire equity securities) to no more than $10,000 in any fiscal year, so long as no default shall exist at the time of or arise as a result from such payment.

On May 5, 2020 (the "Amendment Closing Date"), in response to the COVID-19 pandemic, the Company entered into an amendment to the A&R Credit Agreement (the "Amended A&R Credit Agreement"). The amended consolidated leverage ratio requirements are as follows:



Measurement Period Ending	Maximum Consolidated Leverage Ratio
Amendment Closing Date through June 27, 2020	4.50 to 1.00
June 28, 2020 through October 3, 2020	5.00 to 1.00
October 4, 2020 through January 2, 2021	5.25 to 1.00
January 3, 2021 and April 3, 2021	4.75 to 1.00
April 4, 2021 and July 3, 2021	4.00 to 1.00
July 4, 2021 and thereafter	3.50 to 1.00

The Amended A&R Credit Agreement also amended pricing terms which remain variable and tied to a Eurocurrency rate equal to LIBOR plus an applicable margin or a base rate denominated in U.S. dollars. Interest rates remain subject to change based on the Company's consolidated leverage ratio.
