On October 26, 2018, Orion Energy Systems, Inc. and its subsidiaries (the “Company”) entered into a new secured revolving Business Financing Agreement with Western Alliance Bank, as lender (the “Lender”) (the “Credit Agreement”). The Credit Agreement replaced the Company’s existing $15.0 million secured revolving Credit and Security Agreement dated as of February 6, 2015, by and among the Company and Wells Fargo Bank, National Association, as lender (as previously amended, the “Existing Credit Agreement”).

The Credit Agreement provides for a two-year revolving credit facility (the “Credit Facility”) that matures on October 26, 2020. Borrowings under the Credit Facility are initially limited to $20.15 million, subject to a borrowing base requirement based on eligible receivables and inventory. The Credit Agreement includes a $2.0 million sublimit for the issuance of letters of credit.

The replacement of the Existing Credit Agreement with the Credit Agreement provides the Company with increased financing capacity and liquidity to fund its operations and implement its strategic plans. As of September 30, 2018, the Company had a borrowing base of $1.6 million under the Existing Credit Agreement. Pursuant to the terms of the Credit Agreement, the Company has a borrowing base of $4.0 million, which provides the Company with $2.4 million in additional borrowing availability compared to the Existing Credit Agreement. On October 26, 2018, the Company borrowed $4.0 million under the Credit Agreement.

The Credit Agreement is secured by a security interest in substantially all of the Company’s and its subsidiaries’ personal property.

Borrowings under the Credit Agreement generally bear interest at floating rates based upon the prime rate (but not less than 5.00% per year) plus an applicable margin determined by reference to the Company’s quick ratio (defined as the aggregate amount of unrestricted cash, unrestricted marketable securities and, with certain adjustments, receivables convertible into cash divided by the total current liabilities, including the obligations under the Credit Agreement). Among other fees, the Company is required to pay an annual facility fee equal to 0.45% of the credit limit under the Credit Agreement due on October 26, 2018 and on each anniversary thereof. With certain exceptions, if the Credit Agreement is terminated prior to the first anniversary of the closing date of the Credit Agreement, the Company is required to pay a termination fee equal to 0.50% of the credit limit under the Credit Agreement.

The Credit Agreement requires the Company to maintain nine months’ of “RML” as of the end of each month. For purposes of the Credit Agreement, RML is defined as, as of the applicable determination date, unrestricted cash on deposit with the Lender plus availability under the Credit Agreement divided by an amount equal to, for the applicable trailing three-month period, consolidated net profit before tax, plus depreciation expense, amortization expense and stock-based compensation, minus capital lease principal payments, tested as of the end of each month.

The Credit Agreement also contains customary events of default and other covenants, including certain restrictions on the Company’s ability to incur additional indebtedness, consolidate or merge, enter into acquisitions, pay any dividend or distribution on the Company’s stock, redeem, retire or purchase shares of the Company’s stock, make investments or pledge or transfer assets. If an event of default under the Credit Agreement occurs and is continuing, then the Lender may cease making advances under the Credit Agreement and declare any outstanding obligations under the Credit Agreement to be immediately due and payable. In addition, if the Company becomes the subject of voluntary or involuntary proceedings under any bankruptcy or similar law, then any outstanding obligations under the Credit Agreement will automatically become immediately due and payable.

The foregoing description of the Credit Agreement is qualified in its entirety by reference to the full text of the Credit Agreement, which is filed as Exhibit 10.1 hereto and is incorporated herein by reference.

On October 26, 2018, the Existing Credit Agreement was replaced by the Credit Agreement. All borrowings outstanding under the Existing Credit Agreement were paid off through borrowings under the Credit Agreement, including all amounts outstanding under the Existing Credit Agreement’s $15.0 million revolving credit facility. The Company did not incur any early termination fees in connection with the termination of the Existing Credit Agreement. The Existing Credit Agreement was scheduled to mature on February 6, 2021.

The information disclosed above under Item 1.01 is incorporated herein by reference.
