The Company entered into an Amended and Restated Credit Agreement (the "Credit Facility") with a banking syndicate that allows borrowing under the revolving loan to $300.0 million with the ability to increase the maximum borrowings by $50.0 million, subject to certain conditions. The amended agreement matures on October 8, 2025, with an option to extend on an annual basis, subject to certain conditions. The Credit Facility permits finance lease obligations to a limit of $175.0 million and certain other borrowings outstanding to a limit of $20.0 million. In the amended agreement, the permitted amount of $175.0 million was expanded to include guarantees provided by the Company to certain joint ventures.

As at December 31, 2022, there was $32.0 million (December 31, 2021 - $33.9 million) in issued letters of credit under the Credit Facility and the unused borrowing availability was $88.0 million (December 31, 2021 - $181.1 million). As at December 31, 2022, there was an additional $46.6 million in borrowing availability under finance lease obligations (December 31, 2021 - $28.6 million). Borrowing availability under finance lease obligations considers the current and long-term portion of finance lease obligations and financing obligations, including the finance lease obligations for the joint ventures that the Company guarantees.

The Credit Facility has two financial covenants that must be tested quarterly on a trailing four-quarter basis. As at December 31, 2022, the Company was in compliance with its financial covenants.

•The first covenant is the Senior Leverage Ratio which is Bank Senior Debt plus outstanding letters of credit compared to Bank EBITDA less NACG Acheson Ltd. rental revenue.

◦"Bank Senior Debt" is defined as the Company's long-term debt, finance leases and outstanding letters of credit, excluding Convertible Debentures, deferred financing costs, mortgages related to NACG Acheson Ltd. and debt related to investment in affiliates and joint ventures.

◦"Bank EBITDA" is defined as earnings before interest, taxes, depreciation and amortization, excluding the effects of unrealized foreign exchange gain or loss, realized and unrealized gain or loss on derivative financial instruments, cash and non-cash stock-based compensation expense, gain or loss on disposal of property, plant and equipment, and certain other non-cash items included in the calculation of net income.

◦The Senior Leverage Ratio must be less than or equal to 3.0:1. In the event the Company enters into a material acquisition, the maximum allowable Senior Leverage Ratio would include a step up of 0.50x for four quarters following the acquisition.

The Credit Facility bears interest at Canadian prime rate, U.S. Dollar Base Rate, Canadian bankers’ acceptance rate or the Secured Overnight Financing Rate ("SOFR") (all such terms as used or defined in the Credit Facility), plus applicable margins. The Company is also subject to non-refundable standby fees, 0.40% to 0.75% depending on the Company's Total Debt to Bank EBITDA Ratio. Total debt ("Total Debt") is defined in the Credit Facility as long-term debt including finance leases and letters of credit, excluding convertible debentures, deferred financing costs, the mortgage related to NACG Acheson Ltd., and other non-recourse debt. The Credit Facility is secured by a first priority lien on all of the Company's existing and after-acquired property excluding the Company's first securities interests on the Business Development Bank of Canada ("BDC") mortgage.
