(the “Company”), and the Company’s subsidiary Hudson Holdings, Inc., as borrowers (collectively, the “Borrowers”), and the Company, as guarantor, became obligated under a Credit Agreement (the “Term Loan Facility”) with TCW Asset Management Company LLC, as administrative agent (“Term Loan Agent”) and the lender parties thereto (the “Term Loan Lenders”). Under the terms of the Term Loan Facility, the Borrowers have immediately borrowed $85 million pursuant to a term loan (the “Term Loan”). Amounts borrowed under the Term Loan Facility were used by the Borrowers to repay the outstanding principal amount and related fees and expenses under the Prior Term Loan Facility (as defined below) and for other corporate purposes. The Term Loan matures on March 2, 2027, or earlier upon certain acceleration or cross default events. Principal payments on the Term Loan are required on a quarterly basis, commencing with the quarter ending March 31, 2022, in the amount of 5% of the original principal amount of the outstanding Term Loan per annum. The Term Loan Facility also requires annual payments of 50% of Excess Cash Flow (as defined in the Term Loan Facility); provided that commencing with the year ending December 31, 2023 such payments may be reduced depending upon the Company’s leverage ratio (as defined in the Term Loan Facility) for the applicable year. The Term Loan Facility also requires mandatory prepayments of the Term Loans in the event of certain asset dispositions, debt issuances, and other events. The Term Loan may be prepaid at the option of the Borrowers subject to a prepayment premium of 3% in year one, 2% in year two, 1% in year three, and zero in year four and thereafter. Interest on the Term Loan is generally payable monthly, in arrears. Interest charges with respect to the Term Loan are computed on the actual principal amount of the Term Loan outstanding at a rate per annum equal to (A) with respect to Base Rate loans, the sum of (i) a rate per annum equal to the higher of (1) 2.0%, (2) the federal funds rate plus 0.5%, (3) one month term SOFR plus 1.0%, and (4) the prime commercial lending rate quoted by The Wall Street Journal, plus (ii) between 6.0% and 7.0% depending on the applicable leverage ratio and (B) with respect to SOFR loans, the sum of the applicable SOFR rate plus between 7.0% and 8.0% depending on the applicable leverage ratio. Borrowers and the Company granted to the Term Loan Agent, for the benefit of the Term Loan Lenders, a security interest in substantially all of their respective assets, including receivables, equipment, general intangibles (including intellectual property), inventory, subsidiary stock, real property, and certain other assets. The Term Loan Facility contains a fixed charge coverage ratio covenant and a leverage ratio covenant, each tested quarterly. The Term Loan Facility also contains customary non-financial covenants relating to the Company and the Borrowers, including limitations on Borrowers’ ability to pay dividends on common stock or preferred stock, and also includes certain events of default, including payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control. In connection with the closing of the Term Loan Facility, the Company also entered into a Guaranty and Security Agreement, dated as of March 2, 2022 (the “Term Loan Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of the payment and performance of all obligations owing by Borrowers to Term Loan Agent, as agent for the benefit of the Term Loan Lenders. The Term Loan Agent and the Agent (as defined below) have entered into an intercreditor agreement governing the relative priority of their security interests granted by the Borrowers and the Guarantor in the collateral, providing that the Agent shall have a first priority security interest in the accounts receivable, inventory, deposit accounts and certain other assets (the “Revolving Credit Priority Collateral”) and the Term Loan Agent shall have a first priority security interest in the equipment, real property, capital stock of subsidiaries and certain other assets (the “Term Loan Priority Collateral”).

The Amended Wells Fargo facility amended and restated the prior Wells Fargo Facility. Under the terms of the Amended Wells Fargo Facility, the Borrowers may borrow up to $90 million consisting of: (i) $15 million immediately borrowed in the form of a “first in last out” term loan (the “FILO Tranche”) and (ii) from time to time, up to $75 million at any time consisting of revolving loans (the “Revolving Loans”) in a maximum amount up to the lesser of $75 million and a borrowing base that is calculated based on the outstanding amount of the Borrowers’ eligible receivables and eligible inventory, as described in the Amended Wells Fargo Facility. The Amended Wells Fargo Facility also contains a sublimit of $9 million for swing line loans and $2 million for letters of credit. Amounts borrowed under the Amended Wells Fargo Facility may be used for working capital needs, certain permitted acquisitions, and to reimburse drawings under letters of credit. Interest under the Amended Wells Fargo Facility is payable in arrears on the first day of each month. Interest charges with respect to Revolving Loans are computed on the actual principal amount of Revolving Loans outstanding at a rate per annum equal to (A) with respect to Base Rate loans, the sum of (i) a rate per annum equal to the higher of (1) 1.0%, (2) the federal funds rate plus 0.5%, (3) one month term SOFR plus 1.0%, and (4) the prime commercial lending rate of Wells Fargo, plus (ii) between 1.25% and 1.75% depending on average monthly undrawn availability and (B) with respect to SOFR loans, the sum of the applicable SOFR rate plus between 2.36% and 2.86% depending on average quarterly undrawn availability.

In connection with the closing of the Amended Wells Fargo Facility, the Company also entered into a First Amendment to Guaranty and Security Agreement, dated as of March 2, 2022 (the “Amended Revolver Guaranty and Security Agreement”), pursuant to which the Company and certain subsidiaries are continuing to unconditionally guarantee the payment and performance of all obligations owing by Borrowers to Wells Fargo, as Agent for the benefit of the revolving lenders. Pursuant to the Revolver Guaranty and Security Agreement, as amended, Borrowers, the Company and certain other subsidiaries are continuing to grant to the Agent, for the benefit of the Wells Fargo Facility lenders, a security interest in substantially all of their respective assets, including receivables, equipment, general intangibles (including intellectual property), inventory, subsidiary stock, real property, and certain other assets. The Amended Wells Fargo Facility contains a financial covenant requiring the Company to maintain at all times minimum liquidity (defined as availability under the Amended Wells Fargo Facility plus unrestricted cash) of at least $5 million, of which at least $3 million must be derived from availability. The Amended Wells Fargo Facility also contains a springing covenant, which takes effect only upon a failure to maintain undrawn availability of at least $11.25 million or upon an election by the Borrowers to increase the inventory component of the borrowing base, requiring the Company to maintain a Fixed Charge Coverage Ratio (FCCR) of not less than 1.00 to 1.00, as of the end of each trailing period of twelve consecutive months commencing with the month prior to the triggering of the covenant. The FCCR (as defined in the Wells Fargo Facility) is the ratio of (a) EBITDA for such period, minus unfinanced capital expenditures made during such period, to (b) the aggregate amount of (i) interest expense required to be paid (other than interest paid-in-kind, amortization of financing fees, and other non-cash interest expense) during such period, (ii) scheduled principal payments (but excluding principal payments relating to outstanding Revolving Loans under the Amended Wells Fargo Facility), (iii) all net federal, state, and local income taxes required to be paid during such period (provided, that any tax refunds received shall be applied to the period in which the cash outlay for such taxes was made), (iv) all restricted payments paid (as defined in the Amended Wells Fargo Facility) during such period, and (v) to the extent not otherwise deducted from EBITDA for such period, all payments required to be made during such period in respect of any funding deficiency or funding shortfall with respect to any pension plan. The FCCR covenant ceases after the Borrowers have been in compliance therewith for two consecutive months. The Amended Wells Fargo Facility also contains customary non-financial covenants relating to the Company and the Borrowers, including limitations on Borrowers’ ability to pay dividends on common stock or preferred stock, and also includes certain events of default, including payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control. The commitments under the Wells Fargo Facility will expire and the full outstanding principal amount of the loans, together with accrued and unpaid interest, are due and payable in full on March 2, 2027, unless the commitments are terminated and the outstanding principal amount of the loans are accelerated sooner following an event of default or in the event of certain other cross-defaults.
