NOTE 9—LINES OF CREDIT

On March 6, 2018, BIOLASE and two of its wholly-owned subsidiaries (such subsidiaries, together with BIOLASE, the “Borrower”) entered into the Business Financing Agreement. Pursuant to the terms and conditions of the Business Financing Agreement, Western Alliance has agreed to provide the Borrower a secured revolving line of credit permitting the Borrower to borrow or receive letters of credit up to the lesser of $6.0 million (the “Domestic Revolver”) (subject to a $6.0 million credit limit relating to domestic eligible accounts receivable (the “domestic credit limit”) and a $3.0 million credit limit relating to export-related (the “EXIM Revolver”) eligible accounts receivable (the “EXIM credit limit”)) and the borrowing base, which is defined as the sum of the domestic borrowing base (up to 75% of the Borrower’s eligible domestic accounts receivable less such reserves as Western Alliance may deem proper and necessary) and the export-related borrowing base (up to 85% of the Borrower’s eligible export-related accounts receivable less such reserves as Western Alliance may deem proper and necessary). The Business Financing Agreement expires on March 6, 2020, and the Borrower’s obligations thereunder are secured by a security interest in all of the Borrower’s assets.

As of March 31, 2018, the Company had outstanding borrowings totaling approximately $1.8 million, including $0.6 million subject to the domestic credit limit and $1.2 million subject to the EXIM credit limit. There were no restricted cash balances as of March 31, 2018. The Company’s obligations are generally secured by substantially all of the Company’s assets. The total amount available under the Business Financing Agreement as of March 31, 2018 was $2.8 million.

The Business Financing Agreement requires the Company to maintain compliance with certain financial and non-financial covenants, as defined therein. If a default occurs, Western Alliance may declare the amounts outstanding under the Business Financing Agreement immediately due and payable. As of March 31, 2018, the Company was in compliance with these covenants.

Amounts outstanding under the Business Financing Agreement bear interest at a per annum floating rate equal to the greater of 4.5% or the “Prime Rate” published in the Money Rates section of the Western Edition of The Wall Street Journal (or such other rate of interest publicly announced from time to time by Western Alliance as its “Prime Rate”), plus 1.5% with respect to advances made under the line of credit, plus an additional 5.0% during any period that an event of default has occurred and is continuing. The commitment fee under the Business Financing Agreement is 0.25% of the domestic credit limit and 1.75% of the EXIM credit limit and is payable on March 6, 2018 and each anniversary thereof. As of March 31, 2018, the interest rate on both the Domestic Revolver and EXIM Revolver was 6.25%.

Pursuant to the Business Financing Agreement, the Company paid the first of two annual commitment fees totaling $67,500, being 0.25% of the aggregate $6.0 million commitment for the Domestic Revolver and 1.75% of the aggregate $3.0 million commitment for the EXIM Revolver. The commitment fees and the legal costs associated with acquiring the credit facilities were capitalized and are being amortized on a straight-line basis as interest expense over the term of the Business Financing Agreement.

As additional consideration for the lines of credit, the Company also issued the Western Alliance Warrants. For additional information on the Western Alliance Warrants, see Note 4 – Stockholders’ Equity. The fair value of the Western Alliance Warrants was estimated using the Black-Scholes option-pricing model with the following assumptions: expected term of 10 years; volatility of 91.49%; annual dividend per share of $0.00; and risk-free interest rate of 2.88%; and resulted in an estimated fair value of $0.1 million, which was recorded as a liability and resulted in a discount to the credit facilities at issuance. The discount is being amortized on a straight-line basis to interest expense over the term of the Business Financing Agreement.
