NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1—DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

The Company

BIOLASE, Inc. (“BIOLASE” and, together with its consolidated subsidiaries, the “Company”) is a medical device company that develops, manufactures, markets, and sells laser systems in dentistry and medicine. The Company’s products advance the practice of dentistry and medicine for patients and health care professionals. The Company’s proprietary dental laser systems allow dentists, periodontists, endodontists, oral surgeons, and other dental specialists to perform a broad range of minimally invasive dental procedures, including cosmetic, restorative, and complex surgical applications. The Company’s laser systems are designed to provide clinically superior results for many types of dental procedures compared to those achieved with drills, scalpels, and other conventional instruments. The Company has clearance from the Food and Drug Administration (“FDA”) to market and sell its laser systems in the United States and also has the necessary registration to market and sell its laser systems in Canada, the European Union, and many other countries outside the United States.

Basis of Presentation

The unaudited consolidated financial statements include the accounts of BIOLASE and its wholly-owned subsidiaries and have been prepared on a basis consistent with the December 31, 2019 audited consolidated financial statements and include all material adjustments, consisting of normal recurring adjustments and the elimination of all material intercompany transactions and balances, necessary to fairly present the information set forth therein. These unaudited, interim, consolidated financial statements do not include all the footnotes, presentations, and disclosures normally required by accounting principles generally accepted in the United States of America (“GAAP”) for complete consolidated financial statements.

The consolidated results of operations for the three and six months ended June 30, 2020 are not necessarily indicative of the results for the full year. The accompanying consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2019, included in BIOLASE’s Annual Report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission (the “SEC”) on March 30, 2020 (the “2019 Form 10-K”).

Liquidity and Management’s Plans

The Company incurred losses from operations and net losses, and used cash in operating activities for the three and six months ended June 30, 2020. The Company’s recurring losses, level of cash used in operations, and need for additional capital in the future, including uncertainties surrounding the impact of COVID-19, raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.

COVID-19 Risk and Uncertainties and CARES Act

The COVID-19 pandemic has severely impacted global economic activity, tax and many countries and many states in the United States have reacted to the pandemic by instituting quarantines, mandating business and school closures and restricting travel. These mandated business closures have included dental office closures in Europe and the United States for all but emergency procedures. The Company’s salespeople were unable to call on dental customers during these closures. In addition, most dental shows and workshops scheduled in the first and second quarters of 2020 were canceled. There is no assurance that the Company’s sales will return to normal levels during the second half 2020 or at any time thereafter.  The full impact of the COVID-19 outbreak continues to evolve and it is uncertain as to the full magnitude that the pandemic will have on the Company’s financial condition, liquidity, and future results of operations. Management is actively monitoring the global situation on the Company’s financial condition, liquidity, operations, suppliers, industry, and workforce and has taken actions to mitigate the impact including among other things, temporary reductions in pay, furloughs of certain positions and deferrals in payment for cash preservation. Given the daily evolution of the COVID-19 outbreak and the global responses to curb its spread, the Company is not able to estimate the effects of the COVID-19 outbreak on its results of operations, financial condition, or liquidity for fiscal year 2020.

On March 27, 2020, President Trump signed into law the “Coronavirus Aid, Relief, and Economic Security (the “CARES Act”). The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations, increased limitations on qualified charitable contributions, and technical corrections to tax depreciation methods for qualified improvement property.

As of the date of issuance of these unaudited financial statements, the Company is unable to determine any future impact that the CARES Act will have on our financial condition, results of operations, or liquidity.

Paycheck Protection Program Loan (“PPP Loan”)

On April 14, 2020, BIOLASE, Inc., was granted a loan from Pacific Mercantile Bank in the aggregate amount of $2.98 million, pursuant to the Paycheck Protection Program (the “PPP”) under the CARES Act.  See Note 9 for additional information.

The PPP Loan, which was in the form of a Note dated April 13, 2020 issued by the Company, matures on April 13, 2022 and bears interest at a rate of 1.0% per annum, payable monthly commencing on November 1, 2020. The Note may be prepaid by the Company at any time prior to maturity with no prepayment penalties. Funds from the PPP Loan may only be used for payroll costs, costs used to continue group health care benefits, mortgage payments, rent, utilities, and interest on other debt obligations incurred before February 15, 2020. The Company intends to use the entire PPP Loan amount for qualifying expenses. Under the terms of the PPP, certain amounts of the PPP Loan may be forgiven if they are used for qualifying expenses as described in the CARES Act. However, there can be no assurance that the PPP loan will be forgiven.

The application for these funds requires the Company to, in good faith, certify that the current economic uncertainty made the loan request necessary to support the ongoing operations of the Company. This certification further requires the Company to take into account our current business activity and our ability to access other sources of liquidity sufficient to support ongoing operations in a manner that is not significantly detrimental to the business. For further information on the PPP loan see Note 9 to these unaudited consolidated financial statements.

EIDL Loan

On May 22, 2020, the Company executed the standard loan documents required for securing a loan (the “EIDL Loan”) from the United States 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 twelve months from the date of the EIDL Loan in the amount of $731.00. The balance of principal and interest is payable thirty years from the date of the promissory note. In connection with the EIDL Loan, the Company executed the EIDL Loan documents, which include the SBA Secured Disaster Loan Note, dated May 22, 2020, the Loan Authorization and Agreement, dated May 22, 2020, and the Security Agreement, dated May 22, 2020, each between the SBA and the Company. For further information on the EIDL loan see Note 9 to these unaudited consolidated financial statements.

Amendments to the SWK Credit Agreement

As of December 31, 2019, the Company was not in compliance with its debt covenants under its credit agreement dated November 9, 2018 (as amended, the “Credit Agreement”) with SWK Funding, LLC (“SWK”). In March 2020, the Company entered into a Fourth Amendment dated as of March 25, 2020 to its Credit Agreement with SWK (the “Fourth Amendment”). Under the Fourth Amendment, the financial covenant is amended to require consolidated unencumbered liquid assets of no less than $3.0 million as of any date of determination. The Fourth Amendment also adjusted the Minimum Aggregate Revenue and EBITDA (as defined in the Credit Agreement) requirements. Pursuant to the Fourth Amendment to the Credit Agreement, SWK granted the Company a waiver of the Company’s noncompliance with certain financial covenants contained in the Credit Agreement through March 31, 2020.

On May 15, 2020, the Company entered into the Fifth Amendment to its Credit Agreement (the “Fifth Amendment”) with SWK. The Fifth Amendment amends 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 twelve month period ending June 30, 2020, a related waiver of such minimum revenue target in the event that the Company raises equity capital or issues 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 twelve month period ended June 30, 2020, a related waiver of such minimum EBIDTA target in the event that the Company raises equity capital or issues subordinated debt of not less than $10.0 million on or prior to June 30, 2020, and quarterly EBITDA targets. The Fifth Amendment contains representations, warranties, covenants, releases, and conditions customary for a credit agreement amendment of this type.

On June 8, 2020, SWK agreed to extend the deadline by which the Company is required to raise not less than $10.0 million in equity capital or subordinated debt to July 31, 2020 and agreed that the $6.9 million in proceeds from the offering completed on June 10, 2020 shall be counted toward the $10.0 million requirement. On July 22, 2020, the Company consummated the public offering of 18,000 units, each consisting of one share of Series F Convertible Preferred Stock, par value $0.001 per share (“Series F Convertible Preferred Stock”) and 2,500 warrants, each to purchase one share of Common Stock at an exercise price of $0.40 per share, for which it raised gross proceeds of $18,000,000 before the payment of dealer-manager fees and associated offering expenses of approximately $2.2 million. In connection with the Fifth Amendment, on May 15, 2020 the Company entered into the Third Consolidated, Amended and Restated Warrant pursuant to which the Company issued additional warrants to SWK to purchase 63,779 shares of the Company’s Common Stock with a warrant price per share of $0.39198, and adjusted the warrant price per share with respect to 487,198 existing warrant shares previously issued to SWK to $0.39198. For further information on the additional SWK warrants see Note 9 to these unaudited consolidated financial statements. Based on the extension of the compliance deadline to July 31, 2020, the Company was in compliance with or received a waiver for debt covenants as of June 30, 2020.

Due to the uncertainty surrounding the Company’s ability to meet debt covenants in light of the short and long-term impact of COVID-19 on the Company’s business, the Company is not forecasting compliance with its debt covenants in the next twelve months and has classified the Term Loan with SWK Funding, LLC (the “Term Loan”) as a short-term liability.

On August 12, 2020, the Company entered into the Sixth Amendment to the Credit Agreement (“Sixth Amendment”). Under the Sixth Amendment, the interest only period on the loan is extended to May 2022, the loan maturity date is extended to May 9, 2024, the financial covenants are adjusted, and a $0.7 million repayment of the principal amount was required upon execution of the agreement. See Note 15 for additional information.

Revolving Credit Facility

In April 2020, the Company borrowed $3.0 million in connection with its credit facility with Pacific Mercantile Bank under the PMB Loan (as defined below).

In May 2020 it was determined that the Company was not in compliance with the minimum unrestricted cash requirement under the PMB Loan’s existing covenants as of March 31, 2020. In July, 2020, the Company obtained a waiver for the covenant violation and entered into the First Amendment to the Loan and Security Agreement (the “First Amendment”). Under the First Amendment to the PMB Loan, the Company obtained a forbearance waiving non-compliance through August 1, 2020 subject to certain conditions. In addition, the First Amendment to the PMB Loan the loan covenants were modified to include (a) on or before July 31, 2020, the Borrower has received net cash proceeds in the amount of at least $8.0 million from the issuance of equity securities and those funds are deposited into accounts maintained by PMB and (b) the Company maintains unrestricted cash at PMB in an aggregate amount of $1.5 million.

The Company repaid the $3.0 million and as of June 30, 2020, there was no balance outstanding under the PMB Loan.

Registered Direct Offering and Concurrent Private Placement

On June 10, 2020, the Company consummated a registered direct offering of 10,800,000 shares of its common stock (the “Shares”) to certain accredited institutional investors and a concurrent private placement of warrants to purchase 10,800,000 shares of common stock with an exercise price of $0.515 per share (the “June 2020 Warrants”). The June 2020 Warrants are exercisable commencing on the date of their issuance and will expire on the five- year anniversary of the issuance date.

The combined purchase price for one Share and one June 2020 Warrant in the offering was $0.64. The Company received aggregate gross proceeds of approximately $6.9 million in the offering, before deducting approximately $0.8 million in fees to the placement agents and other offering expenses.  For additional information regarding this transaction, see Note 4 to these unaudited consolidated financial statements.

Rights Offering

On July 22, 2020, the Company completed its previously announced rights offering. Pursuant to the Rights Offering, the Company sold an aggregate of 18,000 units consisting of an aggregate of 18,000 shares of Series F Convertible Preferred Stock and 45,000,000 warrants, with each warrant exercisable for one share of Common Stock, resulting in net proceeds to the Company of approximately $15.8 million, after deducting expenses relating to the Rights Offering, including dealer-manager fees and expenses, and excluding any proceeds received upon exercise of any warrants. For additional information regarding this transaction, see Note 15 to these unaudited consolidated financial statements.

As of June 30, 2020, the Company had working capital of approximately $1.8 million. The Company’s principal sources of liquidity as of June 30, 2020 consisted of approximately $5.7 million in cash, cash equivalents and restricted cash and $4.1 million of accounts receivable, net, and approximately $1.0 million of availability under the PMB Loan.  

In order for the Company to continue operations beyond the next 12 months and be able to discharge its liabilities and commitments in the normal course of business, the Company must increase sales of its products, control or potentially reduce expenses and establish profitable operations in order to generate cash from operations or obtain additional funds when needed.

Although the Company consummated an equity raise of gross proceeds of $6.9 million in the second quarter of 2020, the Company may still have to raise additional capital in the future. Additional capital requirements may depend on many factors, including, among other things, the rate at which the Company’s business grows, the COVID-19 pandemic and the actions taken to contain it, demands for working capital, manufacturing capacity, and any acquisitions that the Company may pursue. From time to time, the Company could be required, or may otherwise attempt, to raise capital through either equity or debt offerings. The Company cannot provide assurance that it will be able to successfully enter into any such equity or debt financings in the future or that the required capital would be available on acceptable terms, if at all, or that any such financing activity would not be dilutive to its’ stockholders.

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of these consolidated financial statements in conformity with generally accepted accounting principles in the United States of America requires the Company to make estimates and assumptions that affect amounts reported in the consolidated financial statements and the accompanying notes. Significant estimates in these consolidated financial statements include allowances on accounts receivable, inventory, and deferred taxes, as well as estimates for accrued warranty expenses, goodwill and the ability of goodwill to be realized, revenue deferrals, effects of stock-based compensation and warrants, contingent liabilities, and the provision or benefit for income taxes. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may differ materially from those estimates.

10

Critical Accounting Policies

Information with respect to the Company’s critical accounting policies, which management believes could have the most significant effect on the Company’s reported results and require subjective or complex judgments by management as discussed in the Company’s 2019 audited financial statements included in the Company’s 2019 Form 10-K. Management believes that there have been no significant changes during the six months ended June 30, 2020 in the Company’s critical accounting policies from those disclosed in Item 7 of the 2019 Form 10-K.

Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market (or, if none exists, the most advantageous market) for the specific asset or liability at the measurement date (referred to as the “exit price”). The fair value is based on assumptions that market participants would use, including a consideration of non-performance risk. Under the accounting guidance for fair value hierarchy, there are three levels of measurement inputs. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable, either directly or indirectly. Level 3 inputs are unobservable due to little or no corroborating market data.

The Company’s financial instruments, consisting of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities, and the SWK Loan as discussed in Note 9, approximate fair value because of the nature of these items.

Concentration of Credit Risk, Interest Rate Risk and Foreign Currency Exchange Rate

Financial instruments which potentially expose the Company to a concentration of credit risk consist principally of cash and cash equivalents, restricted cash, and trade accounts receivable. The Company maintains its cash and cash equivalents and restricted cash with established commercial banks. At times, balances may exceed federally insured limits. To minimize the risk associated with trade accounts receivable, management performs ongoing credit evaluations of customers’ financial condition and maintains relationships with the Company’s customers that allow management to monitor current changes in business operations so the Company can respond as needed. The Company does not, generally, require customers to provide collateral before it sells them its products. However, the Company has required certain distributors to make prepayments for significant purchases of products.

Substantially all of the Company’s revenue is denominated in U.S. dollars, including sales to international distributors. Only a small portion of its revenue and expenses is denominated in foreign currencies, principally the Euro and Indian Rupee. The Company’s foreign currency expenditures primarily consist of the cost of maintaining offices, consulting services, and employee-related costs. During the three and six month periods ended June 30, 2020 and 2019, the Company did not enter into any hedging contracts. Future fluctuations in the value of the U.S. dollar may affect the price competitiveness of the Company’s products outside the U.S.

Recent Accounting Pronouncements

Changes to GAAP are established by the Financial Accounting Standards Board (the “FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification.

The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s consolidated financial position and results of operations.

Recently Issued Accounting Standards

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform. This ASU was issued because the London Interbank Offered Rate (LIBOR) is a benchmark interest rate referenced in a variety of agreements that are used by all types of entities. At the end of 2021, banks will no longer be required to report information that is used to determine LIBOR. As a result, LIBOR could be discontinued. Other interest rates used globally could also be discontinued for similar reasons. ASU 2020-04 provides companies with optional guidance to ease the potential

11

accounting burden associated with transitioning away from reference rates that are expected to be discontinued. Companies can apply the ASU immediately. However, the guidance will only be available for a limited time (generally through December 31, 2022). The Company is currently evaluating alternative benchmark rates to replace LIBOR and is still in the process of evaluating the impact that adopting this new accounting standard will have on its consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The standard’s main goal is to improve financial reporting by requiring earlier recognition of credit losses on financing receivables and other financial assets in scope and to replace the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company will be required to use a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. The standard will be effective for the Company beginning January 1, 2023, with early adoption permitted beginning January 1, 2019. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements.

NOTE 3 – REVENUE RECOGNITION

Contracts with Customers

Revenue for sales of products and services is derived from contracts with customers. The products and services promised in customer contracts include delivery of laser systems, imaging systems, and consumables as well as certain ancillary services such as training and extended warranties. Contracts with each customer generally state the terms of the sale, including the description, quantity and price of each product or service. Payment terms are stated in the contract and vary according to the arrangement. Because the customer typically agrees to a stated rate and price in the contract that does not vary over the life of the contract, the Company’s contracts do not contain variable consideration. The Company establishes a provision for estimated warranty expense.

Performance Obligations

At contract inception, the Company assesses the products and services promised in its contracts with customers. The Company then identifies performance obligations to transfer distinct products or services to the customers. In order to identify performance obligations, the Company considers all of the products or services promised in contracts regardless of whether they are explicitly stated or are implied by customary business practices.

Revenue from products and services transferred to customers at a single point in time accounted for 66% and 71% of net revenue for the three and six months ended June 30, 2020 and 81% and 82% for the three and six months ended June 30, 2019, respectively. The majority of the Company’s revenue recognized at a point in time is for the sale laser systems and consumables. Revenue from these contracts is recognized when the customer is able to direct the use of and obtain substantially all of the benefits from the product which generally coincides with title transfer during the shipping process.

Revenue from services transferred to customers over time accounted for 34% and 29% of net revenue for the three and six months ended June 30, 2020 and 19% and 18% for the three and six months ended June 30, 2019, respectively. The majority of the Company’s revenue that is recognized over time relates to product training and extended warranties. Deferred revenue attributable to undelivered elements, which primarily consists of product training, totaled approximately $0.5 million and $0.6 million as of June 30, 2020 and December 31, 2019, respectively.

12

Transaction Price Allocation

The transaction price for a contract is allocated to each distinct performance obligation and recognized as revenue when, or as, each performance obligation is satisfied. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using the best estimate of the standalone selling price of each distinct good or service in a contract. The primary method used to estimate standalone selling price is the observable price when the good or service is sold separately in similar circumstances and to similar customers.

Significant Judgments

Revenue is recorded for extended warranties over time as the customer benefits from the warranty coverage. This revenue will be recognized equally throughout the contract period as the customer receives benefits from the Company's promise to provide such services. Revenue is recorded for product training as the customer attends a training program or upon the expiration of the obligation, which is generally after nine months.

The Company also has contracts that include both the product sales and product training as performance obligations. In those cases, the Company records revenue for product sales at the point in time when the product has been shipped. The customer obtains control of the product when it is shipped, as all shipments are made FOB shipping point, and after the customer selects its shipping method and pays all shipping costs and insurance. The Company has concluded that control is transferred to the customer upon shipment.

Accounts Receivable

Accounts receivable are stated at estimated net realizable value. The allowance for doubtful accounts is based on an analysis of customer accounts and the Company’s historical experience with accounts receivable write-offs. During the first quarter of 2020, the Company recorded an additional allowance for doubtful accounts of approximately $1.0 million due to the uncertainties stemming from the impact of COVID-19.

Contract Liabilities

The Company performs its obligations under a contract with a customer by transferring products and/or services in exchange for consideration from the customer. The Company typically invoices its customers as soon as control of an asset is transferred and a receivable for the Company is established. The Company, however, recognizes a contract liability when a customer prepays for goods and/or services and the Company has not transferred control of the goods and/or services. The opening and closing balances of the Company’s contract liabilities are as follows (in thousands):

The balance of contract assets was immaterial as the Company did not have a significant amount of uninvoiced receivables at June 30, 2020 and December 31, 2019.

The amount of revenue recognized during the six month period ended June 30, 2020 and June 30, 2019 that was included in the opening contract liability balance related to undelivered elements was $0.4 million and $0.3 million, respectively and related to extended warranty contracts was $2.0 million and $0.4 million, respectively.

13

Disaggregation of Revenue

The Company disaggregates revenue from contracts with customers into geographical regions and by the timing of when goods and services are transferred. The Company determined that disaggregating revenue into these categories depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by regional economic factors.

The Company’s revenues related to the following geographic areas were as follows for the periods indicated (in thousands):

Information regarding revenues disaggregated by the timing of when goods and services are transferred is as follows (in thousands):

The Company’s sales by end market were as follows for the periods indicated (in thousands):

The Company acts as the principal in all its imaging equipment distribution sales. The Company takes possession and control of the equipment before they are sold and transferred to the customer. The Company provides the equipment and any related services directly to the customer. The Company has inventory risk before the equipment is transferred to a customer. The Company purchases and obtains the goods before obtaining a contract with a customer. The Company also has discretion in establishing the price sold to the customer for the equipment.

The revenue and percentages of revenue of the Company’s sales by product line were as follows for the periods indicated:

14

Shipping and Handling Costs and Revenues

Shipping and freight costs are treated as fulfillment costs. For shipments to end-customers, the customer bears the shipping and freight costs and has control of the product upon shipment. For shipments to distributors, the distributor bears the shipping and freight costs, including insurance, tariffs and other import/export costs.

NOTE 4—REDEEMABLE PREFERRED STOCK AND STOCKHOLDERS’ EQUITY

Common Stock

At the 2020 Annual Meeting, the Company’s stockholders’ approved a proposal to amend the Company’s Restated Certificate of Incorporation to increase the number of authorized shares of Common Stock from 40,000,000 shares to 180,000,000 shares. On May 28, 2020, the Company filed the amendment with the Secretary of State of the State of Delaware to effect such increase.

Redeemable Preferred Stock

The board of directors of BIOLASE (the “Board”), without further stockholder authorization, may from time to time authorize the issuance of up to 1,000,000 shares of the Company’s preferred stock. Of the 1,000,000 shares of preferred stock, 69,565 shares have been designated as Series E Participating Convertible Preferred Stock, par value $0.001 per share (“Series E Preferred Stock”), and 18,000 shares have been designated as Series F Convertible Preferred Stock, par value $0.001 per share (“Series F Preferred Stock”). In 2019, the Company sold 69,565 shares of Series E Preferred Stock in a private offering. All 69,565 shares of Series E Preferred Stock were automatically converted into 6,956,500 shares of Common Stock upon receipt of the requisite approval at the 2020 Annual Meeting. Upon the conversion, the net proceeds of $4.0 million were reclassified from mezzanine equity to permanent equity. As of June 30, 2020 and December 31, 2019, 0 and 69,565 shares of Series E Preferred Stock were issued and outstanding, respectively.

The shares of Series E Preferred Stock were offered in reliance upon exemptions from registration under the Securities Act of 1933, as amended, afforded by Regulation D and corresponding provisions of state securities laws. The Company subsequently filed a registration statement with the SEC to register the resale of the shares of Common Stock underlying the Series E Preferred Stock.

Stock-Based Compensation

2002 Stock Incentive Plan

The 2002 Stock Incentive Plan (as amended effective as of May 26, 2004, November 15, 2005, May 16, 2007, May 5, 2011, June 6, 2013, October 30, 2014, April 27, 2015, and May 6, 2016, the “2002 Plan”) was replaced by the 2018 Plan (as defined below) with respect to future equity awards. Persons eligible to receive awards under the 2002 Plan included officers, employees, and directors of the Company, as well as consultants. As of June 30, 2020, a total of approximately 3.1 million shares of the Company’s common stock have been authorized for issuance under the 2002 Plan, of which approximately 1.0 million shares of the Company’s common stock have been issued pursuant to options that were exercised and restricted stock units (“RSUs”) that were settled in common stock and 1.1 million shares of common stock have been reserved for outstanding options and unvested RSUs, and no shares are available for future grants.

2018 Stock Incentive Plan

At the annual meeting of stockholders, the Company’s stockholders approved the 2018 Long-Term Incentive Plan (as amended, the “2018 Plan”) which was amended by Amendment No. 1 to the 2018 Plan, approved by the Company’s stockholders at a special meeting on September 21, 2018 and Amendment No. 2 to the 2018 Plan, as approved by the Company’s stockholders on May 15, 2019 and Amendment No. 3 to the 2018 Plan, as approved by the Company’s stockholders on May 15, 2020. The purposes of the 2018 Plan are (i) to align the interests of the Company’s stockholders and recipients of awards under the 2018 Plan by increasing the proprietary interest of such recipients in the Company’s growth and success; (ii) to advance the interests of the Company by attracting and retaining non-employee directors, officers, other employees, consultants, independent contractors and agents; and (iii) to motivate such persons to act in the long-term best interests of the Company and its stockholders.

15

Subject to the terms and conditions of the 2018 Plan, the number of shares authorized for grants under the 2018 Plan is 12.2 million. As of June 30, 2020 a total 4.1 million shares of the Company’s common stock have been reserved for issuance upon the exercise of outstanding options and or settlement of unvested RSUs, and 8.1 million shares of the Company’s common stock remain available for future grants.

The Company recognized stock-based compensation expense of $0.8 million and $0.5 million, for the three months ended June 30, 2020 and 2019 and $1.6 million and $1.2 million for the six month period ended June 30, 2020 and June 30, 2019 respectively.   As of June 30, 2020, the Company had approximately $1.4 million of total unrecognized compensation expense, net of estimated forfeitures, related to unvested share-based compensation arrangements.

Warrants

The Company issues warrants to acquire shares of the Company’s common stock as approved by the Board.

Registered Direct Offering and Concurrent Private Placement

On June 10, 2020, the Company consummated a registered direct offering of 10,800,000 shares of its common stock to certain accredited institutional investors and a concurrent private placement of warrants to purchase up to an aggregate of 10,800,000 shares of common stock with an exercise price of $0.515 per share. The June 2020 Warrants are exercisable commencing on the date of their issuance and will expire on the five- year anniversary of the issuance date. The combined purchase price for one Share and one June 2020 Warrant in the offering was $0.64. The Company received aggregate gross proceeds of approximately $6.9 million in the offering, before deducting fees to the placement agents and other offering expenses of approximately $0.7 million.

Based on the terms and conditions of the warrants, the Company determined that equity classification was appropriate and recognized the values of the commons stock and common stock warrants in excess of par in Additional Paid-In Capital as of June 30, 2020. The Company allocated the net proceeds of $6.2 million to the common stock and warrants based on their relative fair values. The fair value of the warrants was estimated to be at $0.42 per share using the Black-Scholes pricing model with an expected term of 5 years, market price of $0.54 which is the last closing price of our common stock prior to the transaction date, volatility of 109.8% and a risk free rate of 0.45% and an expected dividend yield of 0. Based on the relative fair value of the warrants, the Company allocated approximately $3.9 million to the common stock and $3.0 million to the warrants before issuance costs.

A summary of warrant activity for the six months ended June 30, 2020 is as follows (in thousands, except exercise price amounts):

See Note 9 for information on the Western Alliance Warrants, the SWK Warrants, and the DPG Warrants (each as defined below).

Net Loss Per Share – Basic and Diluted

Basic net loss per share is computed by dividing net loss available to common stockholders by the weighted-average number of shares of the Company’s common stock outstanding for the period. In computing diluted net loss per share, the weighted average number of shares outstanding is adjusted to reflect the effect of potentially dilutive securities.

Outstanding stock options, RSUs and warrants to purchase approximately 18.5 million shares were not included in the calculation of diluted loss per share for the three and six months ended June 30, 2020, as their effect would have been anti-dilutive. For the same 2019 periods, anti-dilutive outstanding stock options and warrants to purchase 5.7 million shares were not included in the computation of diluted loss per share.

Inventory has been reduced by estimates for excess and obsolete amounts totaling $1.3 million and $1.3 million as of June 30, 2020 and December 31, 2019, respectively.

Depreciation and amortization expense related to property, plant, and equipment totaled $0.3 million and $0.5 million for the three and six months ended June 30, 2020 and $0.3 million and $0.5 million for the three and six months ended June 30, 2019, respectively.

NOTE 7—INTANGIBLE ASSETS AND GOODWILL

The Company conducted its annual impairment test of goodwill as of June 30, 2020 and determined that there was no impairment. The Company also tests its intangible assets and goodwill between the annual impairment tests if events occur or circumstances change that would more likely than not reduce the fair value of the Company or its assets below their carrying amounts. For intangible assets subject to amortization, the Company performs its impairment test when indicators, such as reductions in demand or significant economic slowdowns, are present. No events have occurred since June 30, 2020 through the date of these unaudited consolidated financial statements that would trigger further impairment testing of the Company’s intangible assets and goodwill.

As of June 30, 2020 and December 31, 2019, the Company had goodwill (indefinite life) of $2.9 million. As of June 30, 2020 and December 31, 2019, all intangible assets have been fully amortized and no amortization expense was recognized during the three and six months ended June 30, 2020 and 2019.

19

Changes in the initial product warranty accrual and the expenses incurred under the Company’s initial and extended warranties for the three and six months ended June 30, 2020 and 2019 are included within accrued liabilities and other liabilities in the Consolidated Balance Sheets and were as follows (in thousands):

The Company’s Waterlase laser systems sold worldwide are covered by a warranty against defects in material and workmanship for a period of up to 16 months domestically and up to 28 months internationally, from the date of sale by the Company or a distributor to the end-user. The Company’s Diode systems sold worldwide are covered by a warranty against defects in material and workmanship for a period of up to 28 months from the date of sale by the Company or a distributor to the end-user.

Lines of Credit

Pacific Mercantile Bank

On October 28, 2019, the Company entered into a loan and security agreement (the “Loan Agreement”) with Pacific Mercantile Bank, as lender (the “Lender”), which provides for a revolving line of credit (the “PMB Loan”) in a maximum principal amount not to exceed the lesser of (i) $3 million or (ii) the sum of 90% of the Eligible Accounts (as defined in the Loan Agreement) plus 75% of the Eligible Inventory (as defined in the Loan Agreement, and subject to certain limitations set forth therein); provided that the maximum principal amount of the PMB Loan may be reduced from time to time in the Lender’s good faith business judgment as set forth in the Loan Agreement. Borrowings under the PMB Loan may be used for working capital. The PMB Loan matures on October 28, 2021, unless earlier terminated.

The Company’s obligations under the Loan Agreement are secured by a security interest in substantially all of the Company’s property. No borrowings may be made under the Loan Agreement unless and until Exim Bank agrees to guarantee the PMB Loan and the Company has entered into a borrower agreement with Exim Bank.

Borrowings under the PMB Loan bear interest at a daily rate equal to the prime rate published in the Wall Street Journal, plus 1.5% per annum; provided, that the interest rate in effect on any day shall not be less than 6.0% per annum. Additionally, the Company was required to pay an initial fee and is required to pay an annual fee of $52,500 as well as a termination fee equal to $30,000 in the event the Loan Agreement is terminated on or prior to October 28, 2020.

The Loan Agreement requires the Company to maintain unrestricted cash at the Lender plus unused availability under the PMB Loan in an amount equal to at least the Burn Rate. “Burn Rate” means the Company’s net profit/net loss plus depreciation plus amortization plus stock-based compensation, measured on a trailing three month basis. In addition, the Loan Agreement contains customary affirmative and negative covenants for financings of its type (subject to customary exceptions).

In April, 2020, the Company drew $3.0 million under the PMB Loan and repaid the balance in full during the second quarter.  Interest incurred on the loan was not material. In May 2020 it was determined that the Company was not in compliance with the minimum unrestricted cash requirement under the PMB Loan’s existing covenants as of March 31, 2020. In July, 2020, the Company obtained a waiver for the covenant violation and entered into the First Amendment to the Loan and Security Agreement (the “First Amendment”). Under the First Amendment to the PMB Loan, the Company obtained a forbearance waiving non-compliance through August 1, 2020 subject to certain conditions. In addition, the First Amendment to the PMB Loan the loan covenants were modified to include (a) on or before July 31, 2020, the Borrower has received net cash proceeds in the amount of at least $8.0 million from the issuance of equity securities and those funds are deposited into accounts maintained by PMB and (b) the Company maintains unrestricted cash at PMB in an aggregate amount of $1.5 million.

As of June 30, 2020 and December 31, 2019, the Company had no borrowings outstanding and unused availability under this credit facility of approximately $1.0 million and $2.7 million, respectively

Term Loan

On November 9, 2018, the Company entered into a five-year secured Credit Agreement with SWK Funding LLC (“SWK”), pursuant to which the Company has borrowed $12.5 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 will begin in the first quarter of 2021 and will be approximately $0.7 million quarterly until the loan matures in the fourth quarter of 2023. The loan bears interest at the London Interbank Bank 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 the business financing agreement entered into in 2018.

21

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, including a $0.2 million loan origination fee, a $0.4 million finder’s fee, and $0.4 million in legal and other fees. 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 (a) adjust minimum revenue and EBITDA levels, (b) 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 did not reach set minimum revenue levels for the three-month period ended September 30, 2019, and (c) 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. In 2019, the Company obtained additional equity financing greater 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 Company’s 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 to purchase the Company’s 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.

On September 30, 2019, BIOLASE, Inc entered into the Second Amendment to Credit Agreement (the “Second Amendment”) with SWK, in connection with that certain Credit Agreement, by and among the Company, SWK, and the lender parties thereto.  The Second Amendment amended 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 is 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. 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 and the impact of this was de minimis.

22

As of December 31, 2019, the Company was not in compliance with the covenants under the Credit Agreement, as amended, and on March 25, 2020, the Company agreed to further amend the Credit Agreement (“Fourth Amendment”). Pursuant to the Fourth Amendment to the Credit Agreement, SWK granted the Company a waiver of the Company’s non-compliance with certain financial covenants contained in the Credit Agreement through March 31, 2020. Also pursuant to the Fourth Amendment, the Company and SWK agreed to (i) revise financial covenants to adjust minimum revenue and EBITDA levels and (ii) revise the financial covenant with respect to required unencumbered liquid assets.

On May 15, 2020, the Company entered into the Fifth Amendment to its Credit Agreement with SWK (the “Fifth Amendment”). The Fifth Amendment amended 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 twelve month period ending June 30, 2020, a related waiver of such minimum revenue target in the event that the Company raises equity capital or issues 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 twelve month period ended June 30, 2020, a related waiver of such minimum EBIDTA target in the event that the Company raises equity capital or issues subordinated debt of not less than $10.0 million on or prior to June 30, 2020, and quarterly EBITDA targets. The Fifth Amendment contains representations, warranties, covenants, releases, and conditions customary for a credit agreement amendment of this type. On June 8, 2020, SWK agreed to extend the deadline by which the Company is required to raise not less than $10.0 million in equity capital or subordinated debt to July 31, 2020 and agreed that the $6.9 million in proceeds from the offering completed on June 10, 2020 shall be counted toward the $10.0 million requirement On July 22, 2020, the Company consummated the public offering of 18,000 units, each consisting of one share of Series F Convertible Preferred Stock, par value $0.001 per share (“Series F Convertible Preferred Stock”) and 2,500 warrants, each to purchase one share of Common Stock at an exercise price of $0.40 per share, for which it raised gross proceeds of $18.0 million before the payment of dealer-manager fees and associated offering expenses. Based on the extension of the compliance deadline to July 31, 2020, the Company was in compliance with or received a waiver for debt  covenants as of June 30, 2020.

The Company does not anticipate it will regain compliance with the financial covenants under the Credit Agreement by September 30, 2020 due to the uncertainty surrounding the impact of COVID-19 on its business. Therefore the Term Loan is classified as a current liability in the unaudited consolidated balance sheets.

The Company recognized approximately $0.6 million and $0.5 million and $1.2 million and $1.0 million in interest expense for the three and six months ending June 30, 2020 and 2019, respectively.  The weighted-average interest rate as of June 30, 2020 was 12.25%.  

Paycheck Protection Program Loan

On April 14, 2020, Biolase, Inc., was granted a loan from Pacific Mercantile Bank in the aggregate amount of $2,980,000.00, pursuant to the Paycheck Protection Program under Division A, Title I of the CARES Act, which was enacted March 27, 2020.

The PPP Loan, which was in the form of a Note dated April 13, 2020 issued by the Company, matures on April 13, 2022 and bears interest at a rate of 1.0% per annum. Interest is payable monthly commencing on November 1, 2020. The Note may be prepaid by the Company at any time prior to maturity with no prepayment penalties. Funds from the PPP Loan may only be used for payroll costs, costs used to continue group health care benefits, mortgage payments, rent, utilities, and interest on other debt obligations incurred before February 15, 2020. The Company intends to use the entire PPP Loan amount for qualifying expenses. Under the terms of the PPP, certain amounts of the PPP Loan may be forgiven if they are used for qualifying expenses as described in the CARES Act. However, there can be no assurance that such PPP loan will be forgiven.

The application for these funds requires the Company to, in good faith, certify that the current economic uncertainty made the loan request necessary to support the ongoing operations of the Company. This certification further requires the Company to take into account our current business activity and our ability to access other sources of liquidity sufficient to support ongoing operations in a manner that is not significantly detrimental to the business.

23

The Company recorded the principal amount of approximately $3.0 million due on the PPP Loan in Non current term loans in the unaudited consolidated balance sheet.  Interest on the PPP Loan was not material.

In July 2020, the Company amended the terms of the PPP Loan. Details of the amendment are discussed in Note 15 to these unaudited consolidated financial statements.

EIDL Loan

On May 22, 2020, the Company executed the standard loan documents required for securing a loan (the “EIDL Loan”) from the United States 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 twelve months from the date of the EIDL Loan in the amount of $731 dollars. The balance of principal and interest is payable thirty years from the date of the promissory note. The principal amounts were recognized as Non current term loans in the consolidated balance sheet at June 30, 2020. Interest on the loan was not material.

Western Alliance Warrants

On March 6, 2018, the Company issued to Western Alliance warrants (the “Original Western Alliance Warrants”) to purchase up to the number of shares of common stock equal to $120,000 divided by the applicable exercise price at the time such warrants are exercised. The Original Western Alliance Warrants are fully vested and exercisable. The Original Western Alliance Warrants may be exercised with a cash payment from Western Alliance, or, in lieu of a cash payment, Western Alliance may convert the warrants into a number of shares, in whole or in part. The initial exercise price of the warrants was $2.35 per share. On September 27, 2018, the Company entered into the Second Modification Agreement to amend the Original Business Financing Agreement. In connection with the Second Modification Agreement, the Original Western Alliance Warrants were terminated, and the Company issued new warrants (the “Western Alliance Warrants”) to purchase up to the number of shares of common stock equal to $120,000 divided by the exercise price of $2.13, which was the closing price of the Company’s common stock on September 27, 2018. The Western Alliance Warrants are immediately exercisable and expire on September 27, 2028. These warrants contain down-round features that require the Company to adjust the exercise price proportionately should the Company issue shares at a price per share less than the exercise price.  The sale of common stock in the second quarter of 2020 triggered an adjustment to the exercise price to approximately $0.60 per share.  The impact of the adjustment to the exercise price was not material.

SWK Warrants

In connection with the Credit Agreement, the Company issued warrants to SWK (the “SWK Warrants”) on November 9, 2018, to purchase up to 372,023 shares of the Company’s common stock. The SWK Warrants are immediately exercisable and expire on November 9, 2026. The exercise price of the SWK Warrants is $1.34, which was the average closing price of the Company’s common stock for the ten trading days immediately preceding November 9, 2018. These warrants contain down-round features that require the Company to adjust the exercise price proportionately should the Company issue shares at a price per share less than the exercise price. The fair value of the SWK Warrants was estimated using the Black-Scholes option-pricing model with the following assumptions: expected term of 8 years; volatility of 81.79%; annual dividend per share of $0.00; and risk-free interest rate of 3.13%; and resulted in an estimated fair value of $0.4 million.  

24

In November 2019, these warrants were consolidated and the strike price was adjusted to $1.00, and in March 2020, the strike price was adjusted a second time to $0.49.  The impact of both reprice events was de minimis to the unaudited consolidated financial statements. In connection with the Fifth Amendment, the Company entered into a Third Amendment to the SWK Warrant Agreement. Under this amendment, the Company granted to SWK 63,779 additional common stock warrants at an exercise price of approximately $0.39198. All other terms and conditions to the additional warrants were the same as those previously granted. The Company also revised the exercise price of the 487,198 common stock warrants held by SWK to $0.39198. The Company measured the fair value of the 63,779 warrants granted using the black-Scholes. The fair value of the additional warrants and the aggregate impact of the strike price adjustments in previous amendments to the Warrant Agreement were less than $0.1 million and not material to the unaudited consolidated financial statements. Due to the repricing that occurred in the second quarter of 2020, the down round features of these warrants was not triggered by the Company’s June 2020, sale of common stock.

DPG Warrants

In connection with the SWK Loan, the Company paid a finder’s fee to Deal Partners Group of $0.4 million cash and issued warrants to purchase up to 279,851 shares of common stock (the “DPG Warrants”). The DPG Warrants were issued on November 14, 2018, were exercisable immediately, and expire on November 9, 2026. The exercise price of the DPG Warrants is $1.34 which was the average closing price of the Company’s common stock for the ten trading days immediately preceding November 9, 2018. These warrants contain down-round features that require the Company to adjust the exercise price proportionately should the Company issue shares at a price per share less than the exercise price. The fair value of the DPG Warrants of $0.3 million was estimated using the Black Scholes option pricing model with the following assumptions: expected term of 8 years; volatility of 81.79%; annual dividend per share of $0.00; and risk-free interest rate of 3.13%. In November 2019, the exercise price of the DPG Warrants issued on November 9, 2018 was adjusted from $1.34 per share to $0.8767 per share and the exercise price of the DPG Warrants issued on May, 2019 was adjusted from $2.17 per share to $1.4197 per share. The impact of the reprice was de minimis to the unaudited consolidated financial statements. The June 2020 sale of common stock triggered the down round features of these warrants and in August 2020, the Company adjusted the exercise price of these warrants to $0.62 and $0.38 per share the impact of this reprice was not material.

The value of both the SWK Warrants and the DPG Warrants was recognized as a discount on the SWK Loan and are being amortized on a straight-line basis which approximates the effective-interest method, over the loan term of five years. Additionally, based on the adoption of ASU 2017-11 in the fourth quarter of 2018, these warrants are classified as equity in the consolidated balance sheet as of June 30, 2020.

The future minimum principal and interest payments as of June 30, 2020 are as follows (in thousands):
