On April 26, 2016, Optical Cable Corporation (the “Company”), as borrower, and Bank of North Carolina, as Lender entered into a Credit Agreement (the “Credit Agreement”), a Revolving Credit Note (“Revolver”), as well as certain other ancillary documents to provide the Company with a $7,000,000 revolving line of credit (the “Revolving Loan”). Also on April 26, 2016, the Company, as borrower, and Bank of North Carolina, as Lender, entered into Term Loan A Note in the amount of $1,816,609.03 and Term Loan B Note in the amount of $5,271,410.83 (together, Term Loan A Note and Term Loan B Note are the “Notes”). The Revolving Loan replaced the entire indebtedness the Company had with SunTrust Bank, N.A. The Notes replaced and restated the entire indebtedness the Company had with Bank of North Carolina, as successor to Valley Bank.

The Credit Agreement and Revolver

Under the Credit Agreement and Revolver, the Lender agreed to provide the Company with one or more revolving loans in a collective maximum principal amount of $7,000,000 until February 28, 2017, at which time the Revolving Loan will step down to a maximum principal amount of $6,500,000. On February 28, 2018, the maximum principal amount will again step down to $6,000,000 and remain until the Revolving Loan terminates.

The Revolving Loan is for general corporate purposes including raising working capital and supporting general business operations.

The Company is not obligated to borrow any amount under the Revolving Loan Limit. Within the Revolving Loan Limit, the Company may borrow, repay, and reborrow, at any time or from time to time while the Revolving Loan is in effect.

The Revolving Loan accrues interest at the Adjusted London InterBank Offered Rate plus 3.65%. The Revolving Loan is payable in monthly payment of interest only with principal and any outstanding interest due and payable at maturity. Maturity for the Revolving Loan is February 28, 2018, unless the Revolving Loan is extended.

The Revolving Loan is secured by a perfected first lien security interest on all assets, including but not limited to, Accounts, As-extracted collateral, Chattel Paper, Commodity Accounts, Commodity Contracts, Deposit Accounts, Documents, Equipment, Fixtures, Furniture, General Intangibles, Goods, Instruments, Inventory, Investment Property, Letter of Credit Rights, Payment Intangibles, Promissory Notes, Software and general tangible and intangible assets owned now or later acquired. The Revolving Loan is also cross-collateralized with the Company’s real property located at 5290 Concourse Drive, Roanoke, Virginia and 33 Superior Way, Swannanoa, North Carolina and 112 Buckeye Cove Road, Swannanoa, North Carolina.

During the term of the Revolving Loan, the Company is required to maintain the following financial covenants:

Fixed Charge Coverage Ratio. A Fixed Charge Coverage Ratio of not less than 1.10 to 1.00 for the Company’s fiscal year ending October 31, 2016, stepping up to 1.50 to 1.00 thereafter until maturity of the Revolving Loan. The Fixed Charge Coverage Ratio is defined as Adjusted EBITDA less cash dividends (excluding cash dividends paid in November 2015) paid, all divided by the sum of Annual Debt Service and income taxes paid. Adjusted EBITDA is defined as earnings before interest, taxes, depreciation and amortization excluding non-cash share-based compensation and including any new money equity investments and/or indebtedness fully subordinated to Lender. Annual Debt Service means the sum of all regularly scheduled payments of principal (excluding the required annual $500,000 step downs (when applicable) on the Revolving Loan) plus interest paid.

Debt to Worth. The Company is required to maintain a ratio of Total Liabilities to Tangible Net Worth of no greater than 0.95:1, determined quarterly beginning with the Company’s quarter ending April 30, 2016. Total Liabilities means all liabilities of the Company as set forth in the Company’s financial statements determined in accordance with GAAP. Tangible Net Worth means Total Assets minus Total Liabilities minus any Intangible Assets as set forth in the Company’s financial statements determined in accordance with GAAP.

Current Ratio. The Company is required to maintain a Current Ration of not less than 3.00 to 1.0, monitored quarterly beginning with the Company’s quarter ending April 30, 2016. Current Ratio means Current Assets divided by Current Liabilities, as such terms are classified and determined in accordance with GAAP.
