Revolving Credit Agreement

On February 6, 2015, Orion entered into a credit and security agreement (Credit Agreement) with Wells Fargo Bank, National Association. The Credit Agreement provides for a revolving credit facility (Credit Facility) that matures on February 6, 2018. Borrowings under the Credit Facility are initially limited to $15,000,000 subject to a borrowing base requirement based on eligible receivables and inventory. Such limit may increase to $20,000,000, subject to the borrowing base requirement, after July 31, 2016, if the Company satisfies certain conditions. The Credit Facility includes a $2,000,000 sublimit for the issuance of letters of credit.

From and after any increase in the Credit Facility limit from $15,000,000 to $20,000,000, the Credit Agreement will require Orion to maintain, as of the end of each month, a minimum ratio for the trailing twelve-month period of (i) earnings before interest, taxes, depreciation and amortization, subject to certain adjustments, to (ii) the sum of cash interest expense, certain principal payments on indebtedness and certain dividends, distributions and stock redemptions, equal to at least 1.10 to 1.00. The Credit Agreement also contains other customary covenants, including certain restrictions on Orion’s ability to incur additional indebtedness, consolidate or merge, enter into acquisitions, guarantee obligations of third parties, make loans or advances, declare or pay any dividend or distribution on Orion’s stock, redeem or repurchase shares of Orion’s stock, or pledge or dispose of assets.

As of July 31, 2016, Orion has not satisfied the conditions necessary to increase the borrowing limit to $20,000,000.

Each subsidiary of Orion is a joint and several co-borrower or guarantor under the Credit Agreement, and the Credit Agreement is secured by a security interest in substantially all of Orion’s and each subsidiary’s personal property (excluding various assets relating to customer OTAs) and a mortgage on certain real property.

Borrowings under the Credit Agreement bear interest at the daily three-month LIBOR plus 3.0% per annum, with a minimum interest charge for each year or portion of a year during the term of the Credit Agreement of $130,000, regardless of usage. As of September 30, 2016, the interest rate was 3.85%. Orion must pay an unused line fee of 0.25% per annum of the daily average unused amount of the Credit Facility and a letter of credit fee at the rate of 3.0% per annum on the undrawn amount of letters of credit outstanding from time to time under the Credit Facility.

As of September 30, 2016, Orion had no outstanding letters of credit. Borrowings outstanding as of September 30, 2016, amounted to approximately $4,860,000 and are included in non-current liabilities in the accompanying Condensed Consolidated Balance Sheet. Orion estimates that as of September 30, 2016, it was eligible to borrow an additional $533,000 under the Credit Facility based upon current levels of eligible inventory and accounts receivable.

Orion was in compliance with its covenants in the Credit Agreement as of September 30, 2016.
