NOTE 6 — DEBT

EIDL Loan

On May 22, 2020, the Company executed the standard loan documents required for securing a loan (the “EIDL Loan”) from the Small Business Administration (the “SBA”) under its Economic Injury Disaster Loan assistance program in light of the impact of the COVID-19 pandemic on the Company’s business. The principal amount of the EIDL Loan is $150,000, with proceeds to be used for working capital purposes. Interest on the EIDL Loan accrues at the rate of 3.75% per annum and installment payments, including principal and interest, are due monthly beginning in July 2021 and are payable through July 2050. In April 2021, the SBA announced that it was extending the first payment due date for all loans until 2022, or 24 months from the loan execution date. In March 2022, the SBA announced that it was extending the first payment due date for all loans an additional six months, or 30 months from the loan execution date. The Company began making payments on this EIDL Loan starting in November 2022. Fixed payments are first applied to any accrued interest.

Term Loan

On November 9, 2018, the Company entered into a five-year secured Credit Agreement (as amended, restated, and supplemented from time to time, the “Credit Agreement”) with SWK Funding, LLC (“SWK”), pursuant to which the Company has borrowed $14.35 million (“SWK Loan”). The Company’s obligations under the Credit Agreement are secured by substantially all of the Company’s assets. Under the terms of the Credit Agreement, repayment of the loan is interest-only for the first two years, paid quarterly with the option to extend the interest-only period. Principal repayments were to begin in the first quarter of 2021 and were approximately $0.7 million quarterly until the loan matures in the fourth quarter of 2023. The loan bears interest at the London Interbank Offered Rate (“LIBOR”) plus 10% or another index that approximates LIBOR as close as possible if and when LIBOR no longer exists. Approximately $0.9 million of the proceeds from the SWK Loan were used to pay off all amounts owed to Western Alliance Bank under a previous Business Financing Agreement. The Company used the remaining proceeds to provide additional working capital to fund its growth initiatives.

The Credit Agreement contains financial and non-financial covenants requiring the Company to, among other things, (i) maintain unencumbered liquid assets of (A) no less than $1.5 million or (B) the sum of aggregate cash flow from operations less capital expenditures, (ii) achieve certain revenue and EBITDA levels during the first two years of the loan, (iii) limit future borrowing, investments and dividends, and (iv) submit monthly and quarterly financial reporting.

In connection with the SWK Loan, the Company paid approximately $1.0 million in debt issuance costs, for the year ended December, 31, 2018. These costs were recognized as a discount on the SWK Loan and are being amortized on a straight-line basis over the loan term which approximates the effective-interest method.

As of March 31, 2019, the Company was not in compliance with certain covenants in the Credit Agreement and in May 2019, SWK granted the Company a waiver of such covenants. On May 7, 2019, the Company and SWK agreed to amend the Credit Agreement (the “First Amendment”) to increase the total commitment from $12.5 million to $15.0 million, and to revise the financial covenants to (i) adjust minimum revenue and EBITDA levels, (ii) require the Company to have a shelf registration statement declared effective by the Securities and Exchange Commission before September 30, 2019, with a proposed maximum aggregate offering price of at least $10.0 million if the Company does not reach set minimum revenue levels for the three-month period ended September 30, 2019, and (iii) require minimum liquidity of $1.5 million at all times. The First Amendment provided that if aggregate minimum revenue and EBITDA levels were not achieved by September 30, 2019, the minimum liquidity requirement would be increased to $3.0 million, until the Company has obtained additional equity or debt funding of no less than $5.0 million. The Company borrowed the additional $2.5 million during the year ended December 31, 2019.

In connection with the amendment, the Company paid to SWK loan origination and other fees of approximately $0.1 million payable in cash and approximately $0.2 million in additional SWK Warrants (as defined below) to purchase the BIOLASE common stock. The Company paid an additional finder’s fee to Deal Partners Group (“DPG”) of approximately $0.1 million in cash and $0.1 million in additional DPG Warrants (the “DPG Warrants”) to purchase BIOLASE common stock. The Company accounted for the First Amendment as a modification to existing debt and as a result, recognized the amounts paid to SWK in cash and warrants as additional debt issuance costs. Amounts paid to DPG in cash and warrants relating to the First Amendment were expensed as incurred in the Company’s consolidated statement of operations for the year ended December 31, 2019.

On September 30, 2019, the Company entered into the Second Amendment to the Credit Agreement with SWK (the “Second Amendment”), in connection with that certain Credit Agreement, by and among the Company, SWK, and the lender parties thereto. The Second Amendment amends the Credit Agreement to provide for a permitted inventory and accounts receivable revolving loan facility, secured by a first lien security interest in the Company’s inventory and accounts receivable, with a maximum principal amount of $5 million and with such other material terms and conditions acceptable to SWK in its commercially reasonable discretion. In addition, SWK agreed to waive the effect of the Company’s non-compliance with certain unencumbered liquid assets financial operating covenants as set forth in the Credit Agreement, and SWK agreed to forbear from exercising rights and remedies otherwise available to it in the event of such non-compliance through October 31, 2019, or earlier in the event that an additional equity or subordinated debt financing was consummated with gross proceeds of not less than $5 million, or in the event of a default under the Credit Agreement.

On November 6, 2019, the Company agreed to further amend the Credit Agreement (the “Third Amendment”). Pursuant to the Third Amendment, SWK granted the Company a waiver of the Company’s non-compliance with certain financial covenants in the Credit Agreement. Also pursuant to the Third Amendment, the Company and SWK agreed to (i) revise financial covenants to adjust minimum revenue and EBITDA levels and (ii) remove the automatic increase of the minimum liquidity requirement based on certain aggregate minimum revenue and EBITDA levels as of September 30, 2019 (which was added pursuant to the First Amendment). In connection with the Third Amendment, the Company consolidated the SWK Warrants issued to SWK on November 9, 2018 and May 7, 2019. The price was adjusted to $1.00, the impact of this was immaterial.

As of December 31, 2019, the Company was not in compliance with debt covenants, and in March 2020, the Company obtained a waiver as part of a Fourth Amendment to the Credit Agreement (the “Fourth Amendment”).

On May 15, 2020, the Company entered into a Fifth Amendment to the Credit Agreement (the “Fifth Amendment”). The Fifth Amendment modified the Credit Agreement by providing for minimum consolidated unencumbered liquid assets of $1.5 million prior to June 30, 2020 and $3.0 million on or after June 30, 2020; providing for a minimum aggregate revenue target of $41.0 million for the 12-month period ending June 30, 2020, a related waiver of such minimum revenue target in the event that the Company raised equity capital or issued subordinated debt of not less than $10.0 million on or prior to June 30, 2020, and quarterly revenue targets; and providing for a minimum EBITDA target of ($7.0 million) for the 12-month period ending June 30, 2020, a related waiver of such minimum EBIDTA target in the event that the Company raised equity capital or issued subordinated debt of not less than $10.0 million on or prior to June 30, 2020, and quarterly EBITDA targets.

On August 12, 2020, the Company entered into a Sixth Amendment (the “Sixth Amendment”) to the Credit Agreement. Under the Sixth Amendment, the interest only period on the SWK Loan was extended through May 2022, the loan maturity date was extended to May 9, 2024, the financial covenants were amended and restated to exclude the remainder of 2020, and a $0.7 million repayment of the principal amount was required upon execution of the Sixth Amendment.

In light of the Company's increase in working capital from the Equity Offering (as defined in Note 8 – Redeemable Preferred Stock and Stockholders’ Equity) and cash received from warrants exercised, the Company entered into the Seventh Amendment to the Credit Agreement (the “Seventh Amendment”) with SWK on February 24, 2021, which provided for adjusted minimum aggregate revenue and EBITDA requirements at the end of certain periods, to the extent that the Company's liquid assets are less than $15 million. While the Company's liquid assets are at or above $15 million, no financial maintenance covenants are applicable.

On November 18, 2021, the Company entered into the Eighth Amendment to the Credit Agreement (the “Eighth Amendment”) with SWK. The Eighth Amendment amended the Credit Agreement by providing for a new maturity date of May 31, 2025, extending the interest-only period to May 2023, reducing the effective interest rate by 200 basis points, deleting the definitions of "Key Person" and "Key Person Event", and modifying the minimum aggregate revenue and EBITDA requirements at the end of certain periods, to the extent that liquid assets are less than $7.5 million.

On June 30, 2022, the Company entered into the Ninth Amendment to the Credit Agreement (the "Ninth Amendment") with SWK, which extended the interest-only period by two quarters from May 2023 to November 2023 and lowered the required minimum unencumbered liquid assets. In connection with the Ninth Amendment, the Company prepaid $1.0 million of the outstanding loan balance.

On December 30, 2022, the Company entered into the Tenth Amendment to the Credit Agreement (the "Tenth Amendment") with SWK, which lowered the required minimum unencumbered liquid assets.

In connection with amendments One through Seven to the Credit Agreement, the Company paid certain amendment fees per amendment payable up-front. These fees are being amortized over the remaining life of the SWK Loan as of the date of each amendment.

As of December 31, 2022, the Company was in compliance with debt covenants of the Credit Agreement.

The Company recognized approximately $2.8 million, $1.7 million, and $1.8 million in interest expense related to outstanding loans for the years ended December 31, 2022, 2021 and 2020, respectively. The interest expense for the year ended December 31, 2022 includes an immaterial out of period adjusted related to certain exit fees on the term loan. The weighted-average interest rate for the year ended December 31, 2022 was approximately 11.6%.

Out of Period Adjustment

During the year ended December 31, 2022 an out of period adjustment related to our Credit Agreement with SWK was discovered. Pursuant to the Credit Agreement, we are required to pay certain exit fees totaling $1.4 million upon loan termination. However, on the loan origination date of November 9, 2018, these exit fees were not properly recorded as a debt premium increasing the face value of the loan and an offsetting increase in debt issuance costs to be amortized to interest expense over the life of the loan.

Adjustments were made during the year ended December 31, 2022, resulting in interest expense related to prior periods of $0.8 million. Of this adjustment, $0.2 million relates to the year ended December 31, 2021 and $0.3 million relates to the year ended December 31, 2020. We have evaluated the impact of this out of period adjustment on our financial statements and concluded that it was not material enough to warrant a restatement of historical financials. Nevertheless, we believe it is significant enough to present our historical financials on an "as adjusted" basis.

Warrants

In connection with the Credit Agreement, on November 9, 2018, the Company issued to SWK 372,023 warrants (the “SWK Warrants”), exercisable to 14,881 shares of BIOLASE common stock. In connection with the SWK Loan, the Company paid a finder’s fee to DPG of $0.5 million cash and issued the to DPG 279,851 DPG warrants, exercisable to 11,194 shares of BIOLASE common stock on November 14, 2018, and on May 7, 2019 34,552 warrants, exercisable to 1,382 shares of BIOLASE common stock.
