Revolving Credit and Term Loan Agreement

The Company entered into an Amended and Restated Revolving Credit, Term Loan and Security Agreement, dated October 31, 2011, (“Loan Agreement”), with PNC Bank, National Association (“PNC”), acting as agent and lender. The Loan Agreement, as amended (“Amended Loan Agreement”), provides us with the following Credit Facility: (a) up to $12,000,000 revolving credit facility (“Revolving Credit”), subject to the amount of borrowings based on a percentage of eligible receivables (as defined) and (b) a term loan (“Term Loan”) of $16,000,000, which requires monthly installments of approximately $190,000 (based on a seven-year amortization).

The Amended Loan Agreement terminates as of October 31, 2016, unless sooner terminated. We may terminate the Amended Loan Agreement upon 90 days’ prior written notice and upon payment in full of our obligations under the Amended Loan Agreement.

Our Credit Facility with PNC contains certain financial covenants, along with customary representations and warranties. A breach of any of these financial covenants, unless waived by PNC, could result in a default under our Credit Facility allowing our lender to immediately require the repayment of all outstanding debt under our credit facility and terminate all commitments to extend further credit. The Company met its quarterly fixed charge coverage ratio and minimum tangible adjusted net worth requirements in each of the first and second quarters of 2015.

As of June 30, 2015, the availability under our revolving credit was $3,637,000, based on our eligible receivables and includes an indefinite reduction of borrowing availability of $1,500,000. On July 28, 2014, the Company entered into an amendment to the Amended Loan Agreement which among other things, authorized the Company to use the $3,850,000 insurance settlement proceeds received on June 30, 2014 by our Perma-Fix of South Georgia, Inc. (“PFSG”) subsidiary (which suffered a fire on August 14, 2013 and is included within our discontinued operations) for working capital purposes but placed an indefinite reduction on our borrowing availability by the $1,500,000 as discussed above.

Promissory Notes and Installment Agreements

On February 12, 2013, the Company entered into an unsecured promissory note (“the new note”) with Timios National Corporation (“TNC”) in the principal amount of approximately $230,000 as a result of a settlement with TNC in connection with certain claims that the Company asserted against TNC for breach of certain representations and covenant subsequent to our acquisition of Safety & Ecology Corporation (“SEC”) from TNC on October 31, 2011. The new note was entered into as a result of the settlement in which a previously issued promissory note that the Company entered into with TNC as partial consideration of the purchase price of SEC was cancelled and terminated and replaced with the new note. Final payment of approximately $10,000 on this note was made in January 2015.

On August 2, 2013, the Company completed a lending transaction with Messrs. Robert Ferguson (who serves as an advisor to the Company’s Board of Directors and is also a member of the Board of Directors for our majority-owned Polish subsidiary, Perma-Fix Medical S.A.) and William Lampson (“collectively, the “Lenders”), whereby the Company borrowed from the Lenders the sum of $3,000,000 pursuant to the terms of a Loan and Security Purchase Agreement and promissory note (the “Loan”) (See payment terms of this promissory note in the table above). In connection with this Loan, the Lenders entered into a Subordination Agreement dated August 2, 2013, with the Company’s Credit Facility lender, whereby the Lenders agreed to subordinate payment under the Loan, and agreed that the Loan will be junior in right of payment to the Credit Facility in the event of default or bankruptcy or other insolvency proceeding by the Company. As consideration for the Company receiving the Loan, the Company issued a Warrant to each Lender to purchase up to 35,000 shares of the Company’s Common Stock at an exercise price based on the closing price of the Company’s Common Stock at the closing of the transaction which was determined to be $2.23. The Warrants are exercisable six months from August 2, 2013 and expire on August 2, 2016. The fair value of the Warrants was estimated to be approximately $59,000 using the Black-Scholes option pricing model. As further consideration for the Loan, the Company also issued an aggregate 90,000 shares of the Company’s Common Stock, with each Lender receiving 45,000 shares. The Company determined the fair value of the 90,000 shares of Common Stock to be approximately $200,000 which was based on the closing price of the stock of $2.23 per share on August 2, 2013. The fair value of the Warrants and Common Stock and the related closing fees incurred from the transaction were recorded as a debt discount, which is being amortized using the effective interest method over the term of the loan as interest expense – financing fees.

In the event of default of the promissory note by the Company, the Lenders have the option to receive a cash payment equal to the amount of the unpaid principal balance plus all accrued and unpaid interest (“Payoff Amount”), or the number of whole shares of the Company’s Common Stock equal to the Payoff Amount divided by the closing bid price of the Company’s Common Stock on the date immediately prior to the date of default of the promissory note, as reported by the primary national securities exchange on which the Company’s Common Stock is traded. The maximum number of payoff shares is restricted to less than 20% of the outstanding equity.
