Bank Credit Line

On June 22, 2012, Hudson Technologies Company (“HTC”), an indirect subsidiary of the Company, entered into a Revolving Credit, Term Loan and Security Agreement (the “Original PNC Facility”) with PNC Bank, National Association, as agent (“Agent” or “PNC”), and such other lenders as may thereafter become a party to the Original PNC Facility. Between June 2012 and April 2016, the Company entered into six amendments to the Original PNC Facility. Under the terms of the Original PNC Facility, as amended, the Maximum Loan Amount (as defined in the Original PNC Facility) was $40,000,000 to $50,000,000, and the Maximum Revolving Advance Amount (as defined in the Original PNC Facility) was $46,000,000. In addition, there was a $130,000 outstanding letter of credit under the Original PNC Facility at March 31, 2017. The Termination Date of the Original PNC Facility (as defined in the Original PNC Facility) was June 30, 2020.

On October 10, 2017, HTC and HTC’s affiliates Hudson Holdings, Inc. (“Holdings”) and Airgas-Refrigerants, Inc., as borrowers (collectively, the “Borrowers”), and the Company as a guarantor, became obligated under an Amended and Restated Revolving Credit and Security Agreement (the “PNC Facility”) with PNC Bank, National Association, as administrative agent, collateral agent and lender (“Agent” or “PNC”), PNC Capital Markets LLC as lead arranger and sole bookrunner, and such other lenders as may thereafter become a party to the PNC Facility. The PNC Facility amended and restated the Original PNC Facility.

Under the terms of the PNC Facility, the Borrowers may borrow, from time to time, up to $150 million at any time consisting of revolving loans in a maximum amount up to the lesser of $150 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 PNC Facility. The PNC Facility also contains a sublimit of $15 million for swing line loans and $5 million for letters of credit.

Amounts borrowed under the PNC Facility were used by the Borrowers to consummate the acquisition of ARI and for working capital needs, certain permitted future acquisitions, and to reimburse drawings under letters of credit. At March 31, 2018, total borrowings under the PNC Facility were $52 million, and total availability was $57 million. In addition, there was a $130,000 outstanding letter of credit at March 31, 2018.

Interest on loans under the PNC Facility is payable in arrears on the first day of each month with respect to loans bearing interest at the domestic rate (as set forth in the PNC Facility) and at the end of each interest period with respect to loans bearing interest at the Eurodollar rate (as set forth in the PNC Facility) or, for Eurodollar rate loans with an interest period in excess of three months, at the earlier of (a) each three months from the commencement of such Eurodollar rate loan or (b) the end of the interest period. Interest charges with respect to loans are computed on the actual principal amount of loans outstanding during the month at a rate per annum equal to (A) with respect to domestic rate loans, the sum of (i) a rate per annum equal to the higher of (1) the base commercial lending rate of PNC, (2) the federal funds open rate plus 0.5% and (3) the daily LIBOR plus 1.0%, plus (ii) between 0.50% and 1.00% depending on average quarterly undrawn availability and (B) with respect to Eurodollar rate loans, the sum of the Eurodollar rate plus between 1.50% and 2.00% depending on average quarterly undrawn availability.

Borrowers and the Company granted to the Agent, for the benefit of the 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 PNC Facility contains a financial covenant requiring the Company to maintain at all times a Fixed Charge Coverage Ratio (FCCR) of not less than 1.00 to 1.00, as of the end of each trailing period of four consecutive quarters. The FCCR (as defined in the PNC Facility) is the ratio of (a) EBITDA for such period, minus unfinanced capital expenditures made during such period, minus the aggregate amount of cash taxes paid during such period, to (b) the aggregate amount of all scheduled payments of principal (excluding principal payments relating to outstanding revolving loans under the PNC Facility) and all cash payments of interest, plus cash dividends and distributions made during such period, plus payments in respect of capital lease obligations made during such period. For the fiscal quarters ended on March 31, 2017 and June 30, 2017, EBITDA is deemed to be $21.9 million and $26.1 million, respectively, and for the fiscal quarters ended September 30, 2017 and December 31, 2017 includes EBITDA of ARI on a pro forma basis. As of March 31, 2018 and December 31, 2017, the FCCR was approximately 3.31 to 1 and 6.47 to 1, respectively.

The PNC 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 PNC 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 October 10, 2022, unless the commitments are terminated and the outstanding principal amount of the loans are accelerated sooner following an event of default.

In connection with the closing of the PNC Facility, the Company also entered into an Amended and Restated Guaranty and Suretyship Agreement, dated as of October 10, 2017 (the “Revolver Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of the payment and performance of all obligations owing by Borrowers to PNC, as Agent for the benefit of the revolving lenders.

Term Loan Facility

On October 10, 2017, HTC, Holdings, and ARI, as borrowers, and the Company, as guarantor, became obligated under a Term Loan Credit and Security Agreement (the “Term Loan Facility”) with U.S. Bank National Association, as administrative agent and collateral agent (“Term Loan Agent”) and funds advised by FS Investments and sub-advised by GSO Capital Partners LP and such other lenders as may thereafter become a party to the Term Loan Facility (the “Term Loan Lenders”).

Under the terms of the Term Loan Facility, the Borrowers immediately borrowed $105 million pursuant to a term loan (the “Initial Term Loan”) and may borrow up to an additional $25 million for a period of eighteen months after closing to fund additional permitted acquisitions (the “Delayed Draw Commitment”, and together with the Initial Term Loan, the “Term Loans”).

The Term Loans mature on October 10, 2023. Principal payments on the Term Loans are required on a quarterly basis, commencing with the quarter ending March 31, 2018, in the amount of 1% per annum of the original principal of the outstanding Term Loans. Commencing with the fiscal year ending December 31, 2018, the Term Loan Facility also requires annual principal payments of up to 50% of Excess Cash Flow (as defined in the Term Loan Facility) if the Company’s Total Leverage Ratio (as defined in the Term Loan Facility) for the applicable year is greater than 2.75 to 1.00. The Term Loan Facility also requires mandatory prepayments of the Term Loans in the event of certain asset dispositions, debt issuances, and casualty and condemnation events. The Term Loans may be prepaid at the option of the Borrowers at par in an amount up to $30 million. Additional prepayments are permitted after the first anniversary of the closing date subject to a prepayment premium of 3% in year two, 1% in year three and zero in year four and thereafter.

Interest on the Term Loans is generally payable on the earlier of the last day of the interest period applicable to such Eurodollar rate loan and the last day of the Term Loan Facility, as applicable. Interest is payable at the rate per annum of the Eurodollar Rate (as defined in the Term Loan Facility) plus 7.25%. The Borrowers have the option of paying 3.00% interest per annum in kind by adding such amount to the principal of the Term Loans during no more than five fiscal quarters during the term of the Term Loan Facility.

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 financial covenant requiring the Company to maintain a Total Leverage Ratio (TLR) of not greater than 4.75 to 1.00, tested as of the last day of the fiscal quarter. The TLR (as defined in the Term Loan Facility) is the ratio of (a) funded debt as of such day to (b) EBITDA for the four consecutive fiscal quarters ending on the last day of such fiscal quarter. Funded debt (as defined in the Term Loan Facility) includes amounts borrowed under the PNC Facility and the Term Loan Facility as well as capitalized lease obligations and other indebtedness for borrowed money maturing more than one year from the date of creation thereof. For the fiscal quarters ended on March 31, 2017 and June 30, 2017, EBITDA is deemed to be $21.9 million and $26.1 million, respectively, and for the fiscal quarters ended September 30, 2017 and December 31, 2017 includes EBITDA of ARI on a pro forma basis. As of March 31, 2018 and December 31, 2017, the TLR was approximately 4.23 to 1 and 3.03 to 1, respectively.

The Term Loan Facility also contains customary non-financial covenants relating to the Company and the Borrowers, including limitations on their 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 Suretyship Agreement, dated as of October 10, 2017 (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 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 Company was in compliance with all covenants, under the PNC Facility and the Term Loan Facility as of March 31, 2018. The Company’s ability to comply with these covenants in future quarters may be affected by events beyond the Company’s control, including general economic conditions, weather conditions, regulations and refrigerant pricing. Therefore, we cannot make any assurance that we will continue to be in compliance during future periods.
