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, (“Agreement”), with PNC Bank, National Association (“PNC”), acting as agent and lender. The Agreement, as amended (“Amended Loan Agreement”), provides us with the following credit facilities: (a) up to $12,000,000 revolving credit facility (reduced from $18,000,000 pursuant to an amendment dated April 14, 2014) (“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). As a result of the reduction in the maximum borrowing Revolving Credit noted above, the Company recorded approximately $37,000 in loss on debt modification (included in interest expense) during the second quarter of 2014 in accordance with ASC 470-50, “Debt – Modification and Extinguishment.”

On July 25, 2014, the Company entered into Amendment 5 to the Amended Loan Agreement. This Amendment added our Perma-Fix of Canada, Inc. subsidiary as a guarantor under our credit facility. On July 28, 2014, the Company entered into Amendment 6 to the Amended Loan Agreement. This Amendment authorized the Company to sell our SYA subsidiary and released a hold by PNC which allows the Company to use the $3,850,000 insurance settlement proceeds received on June 30, 2014 by our PFSG subsidiary for working capital purposes but placed an indefinite reduction on our borrowing availability by $1,500,000. As a condition of Amendment 6, the Company agreed to pay PNC a fee of $15,000, which is being amortized over the term of the Amended Loan Agreement. All other terms of the Amended Loan Agreement remains principally unchanged.

The Amended Loan Agreement terminates as of October 31, 2016, unless sooner terminated. The Company 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. No early termination fee shall apply if we pay off our obligations under the Amended Loan Agreement after October 31, 2013.

As of September 30, 2014, the excess availability under our revolving credit was $8,558,000, based on our eligible receivables and includes the indefinite reduction of borrowing availability of $1,500,000 as discussed above.

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 fixed charge coverage ratio requirement for the first quarter of 2014 was waived by PNC. The Company met its fixed charge coverage ratio in the second and third quarters of 2014 and expects to meet its quarterly fixed charge coverage ratio requirement in the remaining quarter of 2014; however, if the Company fails to meet the minimum quarterly fixed charge coverage ratio requirement in the remaining quarter of 2014 and PNC does not waive the non-compliance or further revise our covenant so that the Company is in compliance, our lender could accelerate the repayment of borrowings under our credit facility. In the event that our lender accelerates the payment of our borrowings, the Company may not have sufficient liquidity to repay our debt under our credit facility and other indebtedness.

Promissory Notes

On February 12, 2013, the Company entered into an unsecured promissory note (“the new note”) with Timios National Corporation (“TNC” and formerly known as Homeland Security Capital Corporation) 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 Holdings Corporation and its subsidiaries (collectively known as Safety and Ecology Corporation or “SEC”) from TNC on October 31, 2011 (See payment terms of this promissory note in the table above). The new note was entered into as a result of the settlement in which a previously issued promissory note (with principal balance of $1,460,000 at February 12, 2013) 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. The outstanding principal balance of the new note as of September 30, 2014, was approximately $40,000. The new note provides the Company the right to prepay such at any time without interest or penalty.

In the event of default of the new note payable to TNC by the Company, TNC has the option to convert the unpaid portion of the new note into a number of whole shares of the Company’s restricted Common Stock. The number of shares of the Company’s restricted Common Stock issuable is determined by the principal amount owing under the new note at the time of default plus all accrued and unpaid interest and expenses (as defined) divided by the average of the closing price per share of the Company’s Common Stock as reported by the primary national securities exchange on which the Company’s Common Stock is traded during the 30 consecutive trading day period ending on the trading day immediately prior to receipt by the Company of TNC’s written notice of its election to receive the Company’s restricted Common Stock as a result of the event of default by the Company, with the number of shares of the Company’s Common Stock issuable upon such default subject to certain limitations.

On August 2, 2013, the Company completed a lending transaction with Messrs. Robert Ferguson 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). The Lenders are stockholders of the Company, having received shares of our Common Stock in connection with the acquisition of our Perma-Fix Northwest Richland, Inc. subsidiary (“PFNWR”) in June 2007. The proceeds from the Loan were used for general working capital purposes. 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.
