BIOLASE, Inc. (“BIOLASE” and, together with its consolidated subsidiaries, the “Company”), incorporated in Delaware in 1987, is a medical device company that develops, manufactures, markets, and sells laser systems in dentistry and medicine and also markets, sells, and distributes dental imaging equipment, including three-dimensional CAD/CAM intra-oral scanners and digital dentistry software.

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, 2017 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 nine months ended September 30, 2018 are not necessarily indicative of the results for the full year. The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2017, included in BIOLASE’s Annual Report on Form 10-K for the year ended December 31, 2017 filed with the Securities and Exchange Commission (the “SEC”) on March 14, 2018 (the “2017 Form 10-K”).

The Company incurred a loss from operations and a net loss, and used cash in operating activities for the three and nine months ended September 30, 2018. The Company’s recurring losses, level of cash used in operations, and potential need for additional capital, along with uncertainties surrounding the Company’s ability to raise additional capital, 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.

On March 6, 2018, BIOLASE and two of its wholly-owned subsidiaries (such subsidiaries, together with BIOLASE, the “Borrower”) entered into a Business Financing Agreement (the “Original Business Financing Agreement”) with Western Alliance Bank (“Western Alliance”), which provided for borrowings of up to $6.0 million. On August 13, 2018, the Borrower and Western Alliance entered into a Business Financing Modification Agreement, pursuant to which Western Alliance waived the Borrower’s covenant defaults and provided an advance of $1.5 million, which advance was due by September 27, 2018. On September 27, 2018, the Borrower and Western Alliance entered into a Business Financing Modification Agreement (the “Second Modification Agreement”) which reduced the credit limit under the Original Business Agreement (as amended on August 13, 2018 and September 27, 2018, such agreement the “Business Financing Agreement”) to $2.5 million and extended the due date of the $1.5 million advance to March 6, 2019. The Company had $1.5 million of borrowings outstanding under the Business Financing Agreement as of September 30, 2018. On October 26, 2018, the Borrower and Western Alliance entered into a new Business Financing Modification Agreement. See Note 9 – Lines of Credit and Note 14 – Subsequent Events for additional information.

As of September 30, 2018, the Company had working capital of approximately $10.8 million. The Company’s principal sources of liquidity as of September 30, 2018 consisted of approximately $2.4 million in cash and cash equivalents and restricted cash and $11.4 million of accounts receivable.

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 directly to end-users and through distributors, establish profitable operations through the combination of increased sales and decreased expenses, generate cash from operations or obtain additional funds when needed. The Company intends to improve its financial condition and ultimately improve its financial results by increasing revenues through expansion of its product offerings, continuing to expand and develop its field sales force and distributor relationships, both domestically and internationally, forming strategic arrangements within the dental and medical industries, educating dental and medical patients as to the benefits of its advanced medical technologies, and reducing expenses.

Additional capital requirements may depend on many factors, including, among other things, continued losses, the rate at which the Company’s business grows, 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, or enter into an additional line of credit facility. As discussed in Note 9, on March 6, 2018, the Borrower and Western Alliance entered into the Original Business Financing Agreement, providing for a secured line of credit, which was modified on August 13, 2018, September 27, 2018 and October 26, 2018. On November 9, 2018, BIOLASE entered into a five-year secured Credit Agreement (the “Credit Agreement”) with SWK Funding LLC (“SWK”), pursuant to which the Company has borrowed $12.5 million. See Note 14 – Subsequent Event for additional information. The Company cannot provide assurance that it will be able to successfully consummate any equity or debt financings or enter into any other line of credit facility in the future. The Company also cannot provide assurance that the required capital would be available on acceptable terms, if at all, or that any such financing activity would not be dilutive to the Company’s stockholders.

Except as the context otherwise requires, all share numbers and share price amounts (including exercise prices and closing market prices) contained in the unaudited financial statements and notes thereto reflect the reverse stock split effectuated by the Company on May 10, 2018. See Note 4 – Stockholders’ Equity for additional information.

The preparation of these consolidated financial statements in conformity with GAAP 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, 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.

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 is contained in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the 2017 Form 10-K. Management believes that there have been no significant changes during the nine months ended September 30, 2018 in the Company’s critical accounting policies from those disclosed in Item 7 of the 2017 Form 10-K.

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 nonperformance 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 reflect input other than quoted prices included in Level 1 that are observable, either directly or through collaboration with observable market data, other than Level 1. Level 3 inputs are unobservable due to little or no corroborating market data.

The Company’s financial instruments, consisting of cash, cash equivalents and restricted cash, accounts receivable, loan payable, accounts payable, and accrued liabilities, approximate fair value because of the short maturity of these items.

Changes to GAAP are established by the Financial Accounting Standards Board (“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.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. The standard is effective for annual periods beginning after December 15, 2017, and interim periods therein.

ASU 2014-09 supersedes existing guidance on revenue recognition with a five-step model for recognizing and measuring revenue from contracts with customers. The objective of the new standard is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries, and across capital markets. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The guidance also requires a number of disclosures regarding the nature, amount, timing, and uncertainty of revenue and the related cash flows. The guidance can be applied retrospectively to each prior reporting period presented (full retrospective method) or retrospectively with a cumulative effect adjustment to retained earnings for initial application of the guidance at the date of initial adoption (modified retrospective method). The Company adopted the new standard effective January 1, 2018 using the modified retrospective method applied to those contracts that were not completed or substantially completed as of January 1, 2018. The timing and measurement of revenue recognition under the new standard is not materially different than under the old standard. The adoption of the new standard did not have an impact on the Company’s consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) (“ASU 2016-15”). The updated standard addresses eight specific cash flow issues with the objective of reducing diversity in practice. ASU 2016-15 is effective for public business entities for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. Early adoption is permitted. The Company adopted ASU 2016-15 as of January 1, 2018. The adoption of ASU 2016-15 did not have an impact on the Company’s consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) (“ASU 2016-18”). The updated standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for public business entities for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. The Company adopted ASU 2016-18 as of January 1, 2018. The adoption of ASU 2016-18 did not have a material effect on the Company’s consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation – Stock Compensation (Topic 718) (“ASU 2017-09”). The updated standard clarifies when an entity must apply modification accounting to changes in the terms or conditions of a share-based payment award. ASU 2017-09 is effective for public business entities for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. Early adoption is permitted. The Company adopted ASU 2017-09 as of January 1, 2018. The adoption of ASU 2017-09 did not have a material effect on the Company’s consolidated financial statements.

In February 2016, FASB issued ASU 2016-02, Leases (“ASU 2016-02”). The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact of its pending adoption of ASU 2016-02 on its consolidated financial statements.

In July 2017, FASB issued ASU 2017-11 (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception (“ASU 2017-11”). The new standard simplifies the accounting for certain financial instruments with down round features. Part I of ASU 2017-11 changes the classification analysis of certain equity-linked financial instruments, such as warrants and embedded conversion features, such that a down round feature is disregarded when assessing whether the instrument is indexed to an entity’s own stock under Subtopic 815-40, Contracts in Entity’s Own Equity. As a result, a down round feature, by itself, no longer requires an instrument to be remeasured at fair value through earnings each period, although all other aspects of the indexation guidance under Subtopic 815-40 continue to apply. Part II of ASU 2017-11 recharacterizes the indefinite deferral of certain provisions of Topic 480, Distinguishing Liabilities from Equity, (currently presented as pending content in the Codification) as a scope exception. No change in the Company’s practice is expected as a result of these amendments. The new standard is effective for fiscal years beginning after December 15, 2018, Early adoption is permitted. The amendments in Part II have no accounting impact and therefore do not have an associated effective date. The Company is currently evaluating the impact of its pending adoption of ASU 2017-11 on its consolidated financial statements.

Revenue for sales of products and services is derived from contracts with customers. The products and services promised in 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 services. 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 reserves. For further information on warranty, see Note 8 – Accrued Liabilities.

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 85% of net revenue for both the three and nine months ended September 30, 2018. The majority of the Company’s revenue recognized at a point in time is for the sale laser systems, imaging 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 15% of net revenue for both the three and nine months ended September 30, 2018. The majority of the Company’s revenue that is recognized over time relates to training and extended warranties.

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.

Revenue is recorded for extended warranty 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 training as the customer attends a training program or upon the expiration of the obligation.

The Company also has contracts that include both the product sales and training as performance obligations. In those cases, the Company records revenue for product 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 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.

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 in the periods ended September 30, 2018 and December 31, 2017.

The amount of revenue recognized during the three months ended September 30, 2018 that was included in the opening contract liability balance related to undelivered elements was $0.2 million, related to extended warranty contracts was $0.1 million and deferred royalties was $2,000.

The amount of revenue recognized during the nine months ended September 30, 2018 that was included in the opening contract liability balance related to undelivered elements was $0.8 million, related to extended warranty contracts was $0.7 million and deferred royalties was $8,000.

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

	Three Months Ended						Nine Months Ended

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.

In accordance with Subtopic 340-40 "Other Assets and Deferred Costs - Contracts with Customers,” the Company elected to expense the incremental costs of obtaining a contract when the amortization period for such contracts would have been one year or less.

The Company has made an accounting policy election to exclude all taxes by governmental authorities from the measurement of the transaction price.

At BIOLASE’s annual meeting of stockholders on May 9, 2018 (the “Annual Meeting”), BIOLASE stockholders approved an amendment to BIOLASE’s Restated Certificate of Incorporation, as amended, to effect a reverse stock split of BIOLASE common stock, at a ratio ranging from one-for-five (1:5) to one-for-fifteen (1:15), with the final ratio to be determined by the BIOLASE board of directors (the “Board”). Immediately after the Annual Meeting, the Board approved a one-for-five (1:5) reverse stock split of the outstanding shares of BIOLASE common stock (the “Reverse Stock Split”). On May 10, 2018, the Company filed an amendment (the “Amendment”) to its Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware to effect the Reverse Stock Split, effective as of 11:59 p.m. on May 10, 2018. The Amendment also reduced the authorized shares of common stock from 200,000,000 shares to 40,000,000 shares.

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 September 30, 2018, a total of 3.1 million shares of BIOLASE common stock have been authorized for issuance under the 2002 Plan, of which 1.0 million shares of BIOLASE common stock have been issued pursuant to options that were exercised and restricted stock units (“RSUs”) that were settled in common stock and 1.8 million shares of BIOLASE common stock have been reserved for outstanding options and unvested RSUs.

At the Annual Meeting, BIOLASE stockholders approved the BIOLASE, Inc. 2018 Long-Term Incentive Plan, which was amended by Amendment No. 1 to BIOLASE, Inc. 2018 Long-Term Incentive Plan approved by BIOLASE stockholders at the special meeting of stockholders held on September 21, 2018 (as amended, the “2018 Plan”). 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.

Subject to the terms and conditions of the 2018 Plan, the number of shares authorized for grants under the 2018 Plan is 3.3 million. As of September 30, 2018, a total of 3.3 million shares of BIOLASE common stock have been authorized for issuance under the 2018 Plan, of which 2.4 million shares of BIOLASE common stock have been reserved for outstanding options and unvested RSUs, and 0.9 million shares of BIOLASE common stock remain available for future grants.

The Company recognized stock-based compensation expense of $0.6 million and $0.5 million, for the three months ended September 30, 2018 and 2017, respectively, and $1.9 million and $1.6 million, for the nine months ended September 30, 2018 and 2017, respectively, based on the grant-date fair value. Stock-based compensation expense for the nine months ended September 30, 2018 and 2017 includes the reversal of $0.1 million and $0.7 million, respectively, resulting from the reassessment of certain performance-based equity awards. The net impact of stock-based compensation expense to earnings was $(0.03), and $(0.03) per basic and diluted share for the three months ended September 30, 2018 and 2017, respectively, and $(0.09) and $(0.11) per basic and diluted share for the nine months ended September 30, 2018 and 2017, respectively. At September 30, 2018, the Company had approximately $4.0 million of total unrecognized compensation expense, net of estimated forfeitures, related to unvested share-based compensation arrangements. The Company expects that expense to be recognized over a weighted-average period of 2.1 years.

Effective January 25, 2018, the Compensation Committee of the Board awarded 360,000 non-qualified stock options to purchase shares of BIOLASE common stock to certain employees of the Company. These awards were valued at $2.11 per share, the Reverse Stock Split-adjusted closing market price of BIOLASE common stock on the grant date, and expire 10 years from the grant date. The options vest ratably over the 36-month period, commencing on February 25, 2018.

Under the 2002 Plan, effective January 26, 2018, the Board issued 40,000 RSUs to the Company’s President and Chief Executive Officer. This award was valued at $2.00 per share, the Reverse Stock Split-adjusted closing market price of BIOLASE common stock on the grant date, and will vest upon the achievement of specific annual Company performance criteria.

Under the 2018 Plan, effective September 10, 2018 and September 21, 2018, respectively, the Compensation Committee of the Board granted the following:

Under the 2018 Plan, effective May 14, 2018, the Compensation Committee of the Board granted the following:

Under the 2018 Plan, effective June 15, 2018, the Board granted 155,000 RSUs to two new Board members. These awards were valued at $1.25 per share, the closing price of BIOLASE common stock on the grant date, and vest fully on May 9, 2019.

A summary of unvested RSU activity for the nine months ended September 30, 2018 is as follows (in thousands, except per share amounts):

The Company issues warrants to acquire shares of BIOLASE common stock as approved by the Board. A summary of warrant activity for the nine months ended September 30, 2018 is as follows (in thousands, except exercise price amounts):

On March 6, 2018, in connection with the execution of the Original Business Financing Agreement, the Company issued to Western Alliance warrants (the “Original Western Alliance Warrants”) to purchase up to the number of shares of BIOLASE 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, which was the Reverse Stock Split-adjusted closing market price of BIOLASE common stock on March 6, 2018. 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 BIOLASE 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. See Note 9 – Lines of Credit for further discussion.

Basic net income (loss) per share is computed by dividing income (loss) available to common stockholders by the weighted-average number of shares of BIOLASE common stock outstanding for the period. In computing diluted net income (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 5.8 million shares were not included in the calculation of diluted loss per share for the three and nine months ended September 30, 2018, as their effect would have been anti-dilutive. For the same 2017 periods, anti-dilutive outstanding stock options and warrants to purchase 5.4 million shares were not included in the computation of diluted loss per share.

Inventory is valued at the lower of cost or net realizable value and is comprised of the following (in thousands):

Inventory is net of a provision for excess and obsolete inventory totaling $1.6 million and $1.9 million as of September 30, 2018 and December 31, 2017, respectively.

Property, plant, and equipment, net is comprised of the following (in thousands):

Depreciation and amortization expense related to property, plant, and equipment totaled $0.2 million and $0.7 million for the three and nine months ended September 30, 2018, respectively, and $0.3 million and $0.9 million for the three and nine months ended September 30, 2017, respectively.

The Company conducted its annual impairment test of goodwill as of June 30, 2018 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, 2018 through the date of these consolidated financial statements that would trigger further impairment testing of the Company’s intangible assets and goodwill.

As of September 30, 2018 and December 31, 2017, the Company had goodwill (indefinite life) of $2.9 million. As of September 30, 2018 and December 31, 2017, all intangible assets have been fully amortized. There was no amortization expense for the three and nine months ended September 30, 2018 or 2017.

Changes in the initial product warranty accrual and the expenses incurred under the Company’s initial and extended warranties for the three and nine months ended September 30, 2018 and 2017 are included within accrued liabilities on the Consolidated Balance Sheets and were as follows (in thousands):

On March 6, 2018, the Borrower entered into the Original Business Financing Agreement. Pursuant to the terms and conditions of the Original Business Financing Agreement, Western Alliance 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.

On August 13, 2018, the Borrower and Western Alliance entered into a Business Financing Modification Agreement, pursuant to which Western Alliance waived the Borrower’s covenant defaults under the Original Business Financing Agreement and provided an advance of $1.5 million. This advance was due by September 27, 2018.

On September 27, 2018, the Borrower and Western Alliance entered into the Second Modification Agreement. Pursuant to the terms and conditions of the Second Modification Agreement, the credit limit under the Original Business Financing Agreement was reduced to $2.5 million and the due date of the $1.5 million advance was extended to March 6, 2019. Additionally, the Borrower agreed to certain amended financial covenants contained in the Original Business Financing Agreement (as amended on August 13, 2018), including a revised adjusted quick ratio covenant, and a $750,000 minimum unrestricted cash balance covenant. In addition, pursuant to the Second Modification Agreement, the Borrower agreed to deliver to Western Alliance a term sheet for an equity or debt financing for not less than $5 million in gross proceeds and agreed to close such financing on or before November 15, 2018. See Note 14 – Subsequent Events for information regarding further modifications to the Original Business Financing Agreement.

As of September 30, 2018, the Company had $1.5 million outstanding borrowings under the Domestic Revolver or the EXIM Revolver. There were no restricted cash balances required by the Domestic Revolver or the EXIM Revolver as of September 30, 2018. The Borrower’s obligations are generally secured by substantially all of the Company’s assets. There were no available borrowings under the Business Financing Agreement as of September 30, 2018.

The Business Financing Agreement requires the Borrower 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. The Borrower received a waiver of default from Western Alliance related to certain deliverable covenants as of September 30, 2018.

Amounts outstanding under the Business Financing Agreement bear interest at a per annum floating rate equal to the greater of 5.0% 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 2.25% 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 September 30, 2018, the interest rate on both the Domestic Revolver and EXIM Revolver was 7.5%.

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 Original Western Alliance Warrants. As part of the Second Modification Agreement, the Original Western Alliance Warrants issued on March 6, 2018 were terminated and the Western Alliance Warrants were issued. 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 91.71%; annual dividend per share of $0.00; and risk-free interest rate of 3.08%; 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.

On November 9, 2018, BIOLASE entered into a five-year secured Credit Agreement with SWK, pursuant to which the Company has borrowed $12.5 million. $0.9 million of the proceeds from the SWK Loan have been used to pay off all amounts owed to Western Alliance under the Business Financing Agreement (as amended on October 26, 2018), and the Company plans to use the remaining proceeds to provide additional working capital to fund its growth initiatives, such as broadening its customer base and increasing the utilization of its products to drive recurring higher margin consumables revenue. See Note 14 – Subsequent Event for additional information.

The Company leases its 57,000 square foot corporate headquarters and manufacturing facility located at 4 Cromwell, Irvine, California. In March 2015, the corporate headquarters and manufacturing facility lease was amended to extend the term through April 30, 2020, modify provisions for a tenant improvement allowance of up to $0.4 million, and adjust the basic rent terms. Future minimum rental commitments under operating lease agreements with non-cancelable terms greater than one year for the years ending December 31 are listed below. The Company also leases certain office equipment and automobiles under various operating lease arrangements.

In February 2015, the Company entered into a 30-month capital lease agreement for information technology equipment. In February 2018, the Company extended the agreement for information technology equipment for an additional lease term of 18 months. In accordance with relevant accounting guidance, the renewal of this lease constituted a new lease and is classified by the Company as an operating lease.

Future minimum rental commitments under lease agreements, including both operating and capital leases (principle and interest), with non-cancelable terms greater than one year for each of the years ending December 31 are as follows (in thousands):

Certain members of management are entitled to severance benefits payable upon termination following a change in control, which would approximate $3.2 million, in the aggregate, at September 30, 2018. The Company also has agreements with certain employees to pay bonuses based on targeted performance criteria. As of September 30, 2018, approximately $0.2 million was accrued for performance bonuses, which is included in accrued liabilities in the Consolidated Balance Sheets.

Effective April 10, 2018, Harold C. Flynn, Jr. resigned from the Board and as the Company’s President and Chief Executive Officer. The Company and Mr. Flynn entered into a Separation Agreement, dated as of April 30, 2018 (the “Separation Agreement”). Mr. Flynn is entitled to receive severance in an amount of $365,000, payable through December 28, 2018, along with certain other benefits, including the continued vesting of all of Mr. Flynn’s time-based stock options through April 9, 2020 and an extension of the time to exercise such options through December 31, 2021, subject to immediate vesting upon a change of control, and continued vesting of the time-based RSUs granted to Mr. Flynn on February 6, 2017 through February 6, 2019, subject to immediate vesting upon a change of control. Any unvested stock options following April 9, 2020 will be cancelled and will not vest, and any RSUs that are unvested following February 6, 2019 will be canceled and will not vest. Due to the modification of Mr. Flynn’s equity awards, the Company recognized a net reduction of stock-based compensation expense of approximately $0.3 million, primarily due to the fluctuation in stock prices from the time the awards were granted to when Mr. Flynn resigned and the awards were re-evaluated.

The Company generally purchases components and subassemblies for its products from a limited group of third-party suppliers through purchase orders. As of September 30, 2018, the Company had $9.3 million of purchase commitments for which the Company has not received certain goods or services that are expected to be purchased within one year. These purchase commitments were made to secure better pricing and to ensure the Company will have the necessary parts to meet anticipated near-term demand. Although open purchase orders are considered enforceable and legally binding, the Company may be able to cancel, reschedule or adjust requirements prior to supplier fulfillment.

The Company discloses material loss contingencies deemed to be reasonably possible and accrues for loss contingencies when, in consultation with its legal advisors, management concludes that a loss is probable and reasonably estimable. The ability to predict the ultimate outcome of such matters involves judgments, estimates, and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates.

On April 24, 2012, CAO Group, Inc. (“CAO”) filed a lawsuit against BIOLASE in the District of Utah alleging that BIOLASE’s ezlase dental laser infringes on U.S. Patent No. 7,485,116 (the “116 Patent”). On September 9, 2012, CAO amended its complaint, adding claims for (1) business disparagement/injurious falsehood under common law and (2) unfair competition under 15 U.S.C. Section 1125(a). The additional claims stem from a press release that BIOLASE issued on April 30, 2012, which CAO claims contained false statements that are disparaging to CAO and its diode product. The amended complaint seeks injunctive relief, treble damages, attorneys’ fees, punitive damages, and interest. Until January 24, 2018, this lawsuit was stayed in connection with United States Patent and Trademark Office proceedings relating to the 116 Patent, which proceedings ultimately culminated in a January 27, 2017 decision by the United States Court of Appeals for the Federal Circuit, affirming the findings of the Patent Trial and Appeal Board. On January 25, 2018, CAO moved for leave to file a second amended complaint to add certain claims, which filing the Company did not oppose. The Utah matter has since been transferred to the Central District of California and the two matters have been consolidated with the matter described below.

On January 23, 2018, CAO filed a lawsuit against BIOLASE in the Central District of California alleging that BIOLASE’s diode lasers infringe on U.S. Patent Nos. 8,337,097, 8,834,497, 8,961,040 and 8,967,883. The complaint seeks injunctive relief, treble damages, attorneys’ fees, punitive damages, and interest. The Company is not able to estimate the amount or range of any loss for legal contingencies.

The Company currently operates in a single business segment. Management uses one measurement of profitability and does not segregate its business for internal reporting. For the three and nine months ended September 30, 2018, sales to customers in the United States accounted for approximately 64% and 60% of net revenue, respectively, and international sales accounted for approximately 36% and 40% of net revenue, respectively.

No individual customer represented more than 10% of the Company’s revenue for the three and nine months ended September 30, 2018 or 2017.

The Company maintains its cash and cash equivalent accounts with established commercial banks. Such cash deposits periodically exceed the Federal Deposit Insurance Corporation insured limit.

No individual customer represented more than 10% of the Company’s accounts receivable at September 30, 2018 or December 31, 2017.

The Company currently purchases certain key components of its products from single suppliers. Although there are a limited number of manufacturers of these key components, management believes that other suppliers could provide similar key components on comparable terms. A change in suppliers, however, could cause delays in manufacturing and a possible loss of sales, which could adversely affect the Company’s business, results of operations and financial condition.

The Company accounts for income taxes under the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Management evaluates the need to establish a valuation allowance for deferred tax assets based upon the amount of existing temporary differences, the period in which they are expected to be recovered, and expected levels of taxable income. A valuation allowance to reduce deferred tax assets is established when it is “more likely than not” that some or all of the deferred tax assets will not be realized. Based on the Company’s net losses in prior years, management has determined that a full valuation allowance against the Company’s net deferred tax assets is appropriate.

Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return and provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The Company has elected to classify interest and penalties as a component of its income tax provision. With respect to the liability for unrecognized tax benefits, including related estimates of penalties and interest, the Company did not record a liability for unrecognized tax benefits for the three and nine months ended September 30, 2018 and 2017. The Company does not expect any changes to its unrecognized tax benefit for the next 12 months that would materially impact its consolidated financial statements.

During the three and nine months ended September 30, 2018, the Company recorded an income tax provision of $49,000 and $91,000, respectively, resulting in an effective tax rate of 0.5% and 0.6%, respectively. During the three and nine months ended September 30, 2017, the Company recorded an income tax provision of $35,000 and $111,000 respectively, resulting in an effective tax rate of 0.8% and 0.9%, respectively. The income tax provisions for the three and nine months ended September 30, 2018 and 2017 were calculated using the discrete year-to-date method. The effective tax rate differs from the statutory tax rate of 21% for 2018 and 34% for 2017 primarily due to the existence of valuation allowances against net deferred tax assets and current liabilities resulting from the estimated state income tax liabilities and foreign tax liability.

On December 22, 2017, the U.S. federal government enacted the Tax Cuts and Jobs Act (the “2017 Tax Act”), which enacts a broad range of changes to the Internal Revenue Code of 1986, as amended. Many of the provisions of the 2017 Tax Act take effect for tax years beginning after December 31, 2017, including changes to the U.S. federal corporate tax rate to a flat 21%, significant additional limitations on the deductibility of interest and net operating losses, the allowance for the expensing of certain capital expenditures, and a number of changes impacting operations outside of the United States. The Company’s deferred tax assets and liabilities have been revalued at newly enacted rate in the year of enactment, the impact of which was mostly absorbed by the existing valuation allowance.

The 2017 Tax Act also includes provisions for Global Intangible Low-Taxed Income (“GILTI”) wherein taxes on foreign income are imposed in excess of a deemed return on tangible assets of foreign corporations. This provision is effective for taxable years beginning after December 31, 2017. Because of the complexity of the new GILTI tax rules, the Company continues to evaluate this provision of the 2017 Tax Act including the associated forecast of GILTI and the application of ASC 740, Income Taxes. Under GAAP, the Company is allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred or (2) factoring such amounts into the Company’s measurement of its deferred taxes. The Company’s selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing its global income to determine whether the Company expects to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Whether the Company expects to have future U.S. inclusions in taxable income related to GILTI depends on not only the Company’s current structure and estimated future results of global operations, but also the Company’s intent and ability to modify its structure. The Company is not yet able to reasonably estimate the effect of this provision of the 2017 Tax Act. However, due to the Company’s current net operating loss (“NOL”) position and NOL carryforward balance, the Company does not believe this provision will have a material impact on the Company’s income tax provisions.

Effective October 8, 2018, Elaine C. Wagner was elected to the Board and was appointed to serve as a member of the Compensation Committee of the Board and the Nominating and Corporate Governance Committee of the Board. Upon her election to the Board and her appointment to the Compensation Committee and Nominating and Corporate Governance Committees of the Board, Dr. Wagner received an automatic award of 44,374 stock-settled RSUs, which fully vest on May 9, 2019. Upon vesting, each unit shall be settled with one share of BIOLASE common stock.

On October 26, 2018, the Borrower and Western Alliance entered into a new Business Financing Modification Agreement, pursuant to which Western Alliance waived BIOLASE’s non-compliance with certain financial operating covenants as set forth in the Business Financing Agreement, and the Borrower agreed to certain amended covenants contained in the Business Financing Agreement, including $300,000 minimum unrestricted cash balance covenant and a waiver of reporting items required to be delivered by BIOLASE to Western Alliance under the Business Financing Agreement.

On November 9, 2018, BIOLASE entered into a five-year secured Credit Agreement with SWK, pursuant to which BIOLASE has borrowed $12.5 million (the “SWK Loan”). BIOLASE’s obligations are secured by substantially all of the Company’s assets. The SWK Loan matures on November 9, 2023, and the interest rate on the SWK Loan is LIBOR plus 10%. $0.9 million of the proceeds from the SWK Loan have been used to pay off all amounts owed to Western Alliance under the Business Financing Agreement (as amended on October 26, 2018), and the Company plans to use the remaining proceeds to provide additional working capital to fund its growth initiatives, such as broadening its customer base and increasing the utilization of its products to drive recurring higher margin consumables revenue. On November 9, 2018, in connection with the Credit Agreement, the Company issued warrants to SWK (the “SWK Warrants”) to purchase up to 372,023 shares of BIOLASE 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 BIOLASE common stock for the ten trading days immediately preceding November 9, 2018.

On November 9, 2018, the Business Financing Agreement, as amended on October 26, 2018 (the “Existing Credit Agreement”), was replaced by the Credit Agreement. All outstanding borrowings, accrued interest and fees under the Existing Credit Agreement were paid off with a portion of the proceeds under the Credit Agreement, and the Existing Credit Agreement was terminated.

We are a medical device company that develops, manufactures, markets, and sells laser systems in dentistry and medicine and also markets, sells, and distributes dental imaging equipment, including three-dimensional CAD/CAM intra-oral scanners and digital dentistry software. Our products advance the practice of dentistry and medicine for patients and health care professionals. Our 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. Our 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. We have clearance from the FDA to market and sell our laser systems in the United States and also have the necessary registration to market and sell our laser systems in Canada, the European Union, and many other countries outside the United States. Additionally, our in-licensed imaging equipment and related products improve diagnoses, applications, and procedures in dentistry and medicine.

We offer two categories of laser system products: Waterlase (all-tissue) systems and Diode (soft-tissue) systems. Our flagship brand, the Waterlase, uses a patented combination of water and laser energy to perform most procedures currently performed using drills, scalpels, and other traditional dental instruments for cutting soft and hard tissue. We also offer our Diode laser systems to perform soft tissue, pain therapy, and cosmetic procedures, including teeth whitening. We have approximately 327 issued and 69 pending United States and international patents, the majority of which are related to Waterlase technology. From 1998 through September 30, 2018, we sold over 38,100 laser systems in over 90 countries around the world. Contained in this total are approximately 12,800 Waterlase systems, including approximately 8,800 Waterlase MD, MDX, Express and iPlus systems.

Our Waterlase systems precisely cut hard tissue, bone, and soft tissue with minimal or no damage to surrounding tissue and dental structures. Our Diode systems, which include the Epic system, are designed to complement our Waterlase systems, and are used only in soft tissue procedures, pain therapy, hygiene, and cosmetic applications, including teeth whitening. The Diode systems, together with our Waterlase systems, offer practitioners a broad product line with a range of features and price points.

We also manufacture and sell consumable products and accessories for our laser systems. Our Waterlase and Diode systems use disposable laser tips of differing sizes and shapes depending on the procedure being performed. We also market flexible fibers and hand pieces that dental practitioners replace at some point after initially purchasing laser systems. For our Epic systems, we sell teeth whitening gel kits.

Due to the limitations associated with traditional and alternative dental instruments, we believe there is a large market opportunity for all-tissue dental laser systems that provide superior clinical outcomes, reduce the need to use anesthesia, help reduce trauma, pain, and discomfort associated with dental procedures, and increase patient acceptance for treatment protocols. We also believe there is a large market opportunity for digital radiography systems and CAD/CAM intra-oral scanners that improve practice efficiency and accuracy of diagnosis, leading to superior treatment planning, increased practice revenue, and healthier outcomes for patients.

Our strategy is to increase awareness and demand for (i) our products among dental practitioners by educating dental practitioners and patients about the clinical benefits of our product suite and (ii) our laser systems among patients by educating patients about the clinical benefits of the Waterlase and Diode systems. An important goal of ours is to increase consumables revenue by selling more single-use accessories used by dental practitioners when performing procedures using our dental laser systems. In the short term, we are striving for operating excellence through lean enterprise initiatives, with a specific focus on our sales strategy and cash flow management, coupled with optimizing our engineering capabilities to develop innovative new products.

We also seek to create value through innovation and leveraging existing technologies into adjacent medical applications. We plan to expand our product line and clinical applications by developing enhancements and transformational innovations, including new clinical solutions for dental applications and for other adjacent medical applications. In particular, we believe that our existing technologies can provide significant improvements over existing standards of care in fields including ophthalmology, otolaryngology, orthopedics, podiatry, pain management, aesthetics/dermatology, veterinary, and consumer products. We plan to continue to explore potential collaborations to apply our proprietary laser technologies with expanded FDA-cleared indications to other medical applications in the future.

Effective May 10, 2018, BIOLASE effectuated a one-to-five reverse stock split. In connection with the reverse stock split, the number of authorized shares of BIOLASE common stock was reduced from 200,000,000 shares to 40,000,000 shares. See Part I, Item I, Note 4 – Stockholders’ Equity for additional information.

On November 9, 2018, BIOLASE entered into a five-year secured Credit Agreement with SWK Funding LLC (“SWK”), pursuant to which BIOLASE has borrowed $12.5 million (the “SWK Loan”). BIOLASE’s obligations are secured by substantially all of the Company’s assets. The SWK Loan matures on November 9, 2023, and the interest rate on the SWK Loan is LIBOR plus 10%. $0.9 million of the proceeds from the SWK Loan have been used to pay off all amounts owed to Western Alliance under the Business Financing Agreement (as amended on October 26, 2018), and the Company plans to use the remaining proceeds to provide additional working capital to fund its growth initiatives, such as broadening its customer base and increasing the utilization of its products to drive recurring higher margin consumables revenue.

The unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and revenues and expenses reported during the period. Information with respect to our critical accounting policies that we believe could have the most significant effect on our reported results and require subjective or complex judgments by management is contained in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the 2017 Form 10-K. There have been no significant changes during the nine months ended September 30, 2018 in our critical accounting policies from those disclosed in Item 7 of the 2017 Form 10-K.

The following table sets forth certain data from our unaudited consolidated statements of operations expressed as percentages of net revenue:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,

In addition to the financial information prepared in conformity with GAAP, we provide certain historical non-GAAP financial information. Management believes that these non-GAAP financial measures assist investors in making comparisons of period-to-period operating results and that, in some respects, these non-GAAP financial measures are more indicative of the Company’s ongoing core operating performance than their GAAP equivalents.

Management believes that the presentation of this non-GAAP financial information provides investors with greater transparency and facilitates comparison of operating results across a broad spectrum of companies with varying capital structures, compensation strategies, derivative instruments, and amortization methods, which provides a more complete understanding of our financial performance, competitive position, and prospects for the future. However, the non-GAAP financial measures presented in this Form 10-Q have certain limitations in that they do not reflect all of the costs associated with the operations of our business as determined in accordance with GAAP. Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. Further, the non-GAAP financial measures presented by the Company may be different from similarly named non-GAAP financial measures used by other companies.

Management uses non-GAAP net loss (defined as net loss before interest, taxes, depreciation and amortization and stock-based compensation) in its evaluation of the Company’s core results of operations and trends between fiscal periods and believes that these measures are important components of its internal performance measurement process. Management believes that this non-GAAP financial information reflects an additional way of viewing aspects of our business that, when viewed with our GAAP results, provides a more complete understanding of factors and trends affecting our business. The following table contains a reconciliation of non-GAAP net loss to GAAP net loss attributable to common stockholders (in thousands):

	Three Months Ended						Nine Months Ended

Net Revenue: The following table summarizes our net revenues by category, including each category’s percentage of our total revenue, for the three months ended September 30, 2018 (the “Third Quarter 2018”) and the three months ended September 30, 2017 (the “Third Quarter 2017”), as well as the amount of change and percentage of change in each revenue category (dollars in thousands):

	Three Months Ended				Three Months Ended
	September 30,				September 30,				Amount			Percent
	2018				2017				Change			Change

Typically, we experience fluctuations in revenue from quarter to quarter due to seasonality. Revenue in the first quarter typically is lower than average, and revenue in the fourth quarter typically is stronger than average, due to the buying patterns of dental practitioners. We believe that this trend exists because a significant number of dentists purchase their capital equipment towards the end of the calendar year in order to maximize their practice earnings while seeking to minimize their taxes. They often use certain tax incentives, such as accelerated depreciation methods for purchasing capital equipment, as part of their year-end tax planning. In addition, revenue in the third quarter may be affected by vacation patterns which can cause revenue to be flat or lower than in the second quarter of the year. Our historical seasonal fluctuations may also be impacted by sales promotions used by large dental distributors that encourage end-of-quarter and end-of-year buying in our industry.

Total revenue by geographic location based on the location of customers for the Third Quarter 2018 and Third Quarter 2017, as well as the amount of change and percentage of change in each geographic revenue category, were as follows (dollars in thousands):

The $0.1 million, or 1.2%, overall increase in quarter-over-quarter net revenue resulted primarily from laser systems sales, which increased by $0.7 million, or 11.4%, in the Third Quarter 2018 compared to the Third Quarter 2017. Sales of our laser products increased by 22% domestically and 2% internationally, during the Third Quarter 2018 compared to the Third Quarter 2017. Consumables and other revenue, which consists of consumable products such as disposable tips increased by $0.2 million or 8.6% during the Third Quarter 2018 compared to the Third Quarter 2017.

Partially offsetting increases in laser systems revenue and consumables and other revenue was a decrease in imaging systems revenue. Imaging systems revenue decreased by $0.7 million or 65.4% in the Third Quarter 2018 compared to the Third Quarter 2017, primarily driven by a one-time study club purchase in 2017, along with a renewed focus on laser sales for 2018.

Cost of Revenue and Gross Profit: The following table summarizes our cost of revenue and gross profit for the Third Quarter 2018 and the Third Quarter 2017, as well as the amount of change and percentage of change (dollars in thousands):

Gross profit as a percentage of revenue typically fluctuates with product and regional mix, selling prices, product costs and revenue levels. The 38% increase in gross profit as a percentage of revenue for the Third Quarter 2018, as compared to the Third Quarter 2017, reflects new customer growth and a favorable change in product mix with an increase in laser sales, which have a higher margin than our other product offerings, partially offset by a decrease in imaging sales, as laser sales typically have higher margins. Additionally, there was an increase in the average selling prices.

Operating Expenses: The following table summarizes our operating expenses as a percentage of net revenue for the Third Quarter 2018 and Third Quarter 2017, as well as the amount of change and percentage of change (dollars in thousands):

	Three Months Ended				Three Months Ended
	September 30,				September 30,				Amount			Percent
	2018				2017				Change			Change
Sales and marketing	$	4,489	41.0	%	$	4,000	37.0	%	$	489			12.2	%
General and administrative		2,685	24.6	%		2,015	18.6	%		670			33.3	%
Engineering and development		1,277	11.7	%		1,601	14.8	%		(324	)		(20.2	%)
Total operating expenses	$	8,451	77.3	%	$	7,616	70.4	%	$	835			11.0	%

The quarter-over-quarter total operating expenses are explained in the following expense categories:

Sales and Marketing Expense. Sales and marketing expenses in the Third Quarter 2018 compared to the Third Quarter 2017 increased by $0.5 million, or 12.2%, primarily due to an increase in media materials, advertising and printing expenses of $0.2 million, an increase in payroll and consulting-related expenses of $0.1 million, an increase in commissions of $0.1 million and an increase in travel expenses of $0.1 million. As we continue efforts to transform and drive to revenue growth, we expect sales and marketing expenses to increase as a percentage of revenue.

General and Administrative Expense. General and administrative expenses in the Third Quarter 2018 compared to the Third Quarter 2017 increased by $0.7 million, or 33.3%, primarily due to an increase of $0.5 in legal fees resulting from our efforts to defend our intellectual property, an increase in investor relations-related expenses of $0.1 million and an increase in provision for doubtful accounts of $0.1 million. We expect general and administrative expenses to decrease as a percentage of revenue through the remainder of 2018.

Engineering and Development Expense. Engineering and development expenses in the Third Quarter 2018 compared to the Third Quarter 2017 decreased by $0.3 million, or 20.2%, primarily due to a $0.2 million decrease in payroll and consulting-related expenses. We expect engineering and development expenses to decrease as a percentage of revenue through the remainder of 2018.

Gain (Loss) on Foreign Currency Transactions. We realized a $0.1 million loss on foreign currency transactions during the Third Quarter 2018, compared to a $0.2 million gain on foreign currency transactions during the Third Quarter 2017, due to exchange rate fluctuations between the U.S. dollar and other currencies, primarily the Euro.

Interest Expense (Income), Net. Interest expense during the Third Quarter 2018 represented interest recognized from the amortization of the discount due to allocation value of the warrants issued to Western Alliance Bank (“Western Alliance”) in March 2018, which were terminated and replaced by the new warrants issued to Western Alliance on September 27, 2018. See Part I, Item I, Note 9 – Lines of Credit for additional information. Interest income during the Third Quarter 2017 represented interest recognized from the discounted present value of the settlement in connection with the patent infringement lawsuit against Fotona Proizvodnja Optoelektronskih Naprav D.D. and Fotona LLC (collectively, “Fotona”). We filed the lawsuit in Düsseldorf District Court in April 2012 alleging infringement with respect to the Fotona Fidelis dental laser system.

Income Tax Provision. We use a discrete year-to-date method in calculating quarterly provision for income taxes. Our provision for income taxes was $49,000 for the Third Quarter 2018, compared to a provision of $35,000 for the Third Quarter 2017. For additional information regarding income taxes, see Part I, Item I, Note 13 – Income Taxes.

Net Loss. Our net loss totaled approximately $4.7 million for the Third Quarter 2018 compared to a net loss of $4.6 million for the Third Quarter 2017. The $0.1 million or 1%, increase in net loss was primarily due to a $0.8 million or 11% increase in operating expenses and a $0.2 million negative impact on foreign currency transactions due to a loss for the Third Quarter 2018 compared to a gain for the Third Quarter 2017, offset by a $1.0 million decrease in cost of revenue.

Net Revenue: The following table summarizes our net revenues by category, including each category’s percentage of our total revenue, for the nine months ended September 30, 2018 (“YTD Third Quarter 2018”) and the nine months ended September 30, 2017 (“YTD Third Quarter 2017”), as well as the amount of change and percentage of change in each revenue category (dollars in thousands):

	Nine Months Ended				Nine Months Ended
	September 30,				September 30,				Amount			Percent
	2018				2017				Change			Change
Laser systems	$	20,678	62.5	%	$	21,026	61.3	%	$	(348	)		(1.7	%)

Total products and services		33,101	100.0	%		34,196	99.7	%		(1,095	)		(3.2	%)
License fees and royalty		9	—	%		96	0.3	%		(87	)		(90.6	%)
Net revenue	$	33,110	100.0	%	$	34,292	100.0	%	$	(1,182	)		(3.4	%)

The $1.2 million, or 3.4%, overall decrease in period-over-period net revenue resulted primarily from imaging systems sales, which decreased by $1.3 million, or 50.2%, in YTD Third Quarter 2018 compared to YTD Third Quarter 2017. The imaging systems revenue decrease was driven by a one-time study club purchase in 2017. Laser systems revenue also decreased by $0.3 million or 1.7%, in YTD Third Quarter 2018 compared to YTD Third Quarter 2017.

Partially offsetting the decreased imaging systems revenue and laser systems revenue were increases to consumables and other revenue. Consumables and other revenue, which consists of consumable products such as disposable tips and services, increased by $0.7 million, or 13.6%, in YTD Third Quarter 2018 compared to YTD Third Quarter 2017.

Total revenue by geographic location based on the location of customers for YTD Third Quarter 2018 and YTD Third Quarter 2017, as well as the amount of change and percentage of change in each geographic revenue category, were as follows (dollars in thousands):

Cost of Revenue and Gross Profit: The following table summarizes our cost of revenue and gross profit for YTD Third Quarter 2018 and YTD Third Quarter 2017, as well as the amount of change and percentage of change (dollars in thousands):

Gross profit as a percentage of revenue typically fluctuates with product and regional mix, selling prices, product costs and revenue levels. The 2% decline in gross profit as a percentage of revenue for YTD Third Quarter 2018, as compared to YTD Third Quarter 2017, reflected lower revenue resulting in unabsorbed fixed costs.

Operating Expenses: The following table summarizes our operating expenses as a percentage of net revenue for YTD Third Quarter 2018 and YTD Third Quarter 2017, as well as the amount of change and percentage change (dollars in thousands):

	Nine Months Ended				Nine Months Ended
	September 30,				September 30,				Amount			Percent
	2018				2017				Change			Change
Sales and marketing	$	13,037	39.4	%	$	12,718	37.1	%	$	319			2.5	%
General and administrative		8,691	26.2	%		7,271	21.2	%		1,420			19.5	%
Engineering and development		3,927	11.9	%		4,840	14.1	%		(913	)		(18.9	%)
Total operating expenses	$	25,655	77.5	%	$	24,829	72.4	%	$	826			3.3	%

The period-over-period total operating expenses are explained in the following expense categories.

Sales and Marketing Expense. Sales and marketing expenses in YTD Third Quarter 2018 compared to YTD Third Quarter 2017 increased by $0.3 million, or 2.5%, primarily due to an increase in payroll and consulting-related expenses of $0.5 million and an increase in media, advertising and printing expenses of $0.1 million, partially offset by a decrease in convention-related expenses of $0.4 million. In the first quarter of 2017, we participated in the International Dental Show in Cologne, Germany, which led to higher convention-related expenses and travel expenditures.

General and Administrative Expense. General and administrative expenses in YTD Third Quarter 2018 compared to YTD Third Quarter 2017 increased by $1.4 million or 19.5%, primarily due to an increase of $0.6 million in legal and patent fees resulting from our efforts to protect our intellectual property, an increase of $0.3 million in payroll and consulting-related expenses, an increase of $0.3 million in provision for doubtful accounts and an increase of $0.1 million in investor relations expenses. The increase in payroll and consulting-related expenses is primarily due to an increase in severance expenses of $0.4 million related to the change in CEO. We expect general and administrative expenses to decrease as a percentage of revenue through the remainder of 2018.

Engineering and Development Expense. Engineering and development expenses in YTD Third Quarter 2018 compared to YTD Third Quarter 2017 decreased by $0.9 million, or 18.9%, primarily due to a $0.4 million decrease in operating supplies and a $0.3 million decrease in payroll and consulting-related expenses. The decrease in payroll and consulting-related expenses was driven by a decrease in wages of $0.2 million. We expect engineering and development expenses to decrease as a percentage of revenue through the remainder of 2018.

Gain (Loss) on Foreign Currency Transactions. We realized a loss of $0.1 million on foreign currency transactions during YTD Third Quarter 2018, compared to a $0.4 million gain on foreign currency transactions during YTD Third Quarter 2017, due to exchange rate fluctuations between the U.S. dollar and other currencies, primarily the Euro.

Interest Expense (Income), Net. Interest expense during YTD Third Quarter 2018 represented interest recognized from the amortization of the discount due to allocation value of the warrants issued to Western Alliance in March 2018, which were terminated and replaced by the new warrants issued to Western Alliance on September 27, 2018. See Part I, Item I, Note 9 – Lines of Credit for additional information. Interest income during YTD Third Quarter 2017 represented interest recognized from the discounted present value of the settlement in connection with the Fotona patent infringement lawsuit described above.

Income Tax Provision. Our provision for income taxes was $91,000 for YTD Third Quarter 2018, compared to a provision of $111,000 for YTD Third Quarter 2017. For additional information regarding income taxes, see Part I, Item I, Note 11 – Income Taxes.

Net Loss. Our net loss totaled approximately $14.6 million for YTD Third Quarter 2018 compared to a net loss of $13.0 million for YTD Third Quarter 2017. The $1.6 million or 12%, increase in net loss was due to a $0.8 million, or 3%, increase in operating expenses and a $0.5 million negative impact on foreign currency transactions due to a loss for YTD Third Quarter 2018 compared to a gain YTD Third Quarter 2017.

At September 30, 2018, the Company had approximately $2.4 million in cash, cash equivalents and restricted cash. Management defines cash and cash equivalents as highly liquid deposits with original maturities of 90 days or less when purchased. The decrease in our cash, cash equivalents and restricted cash of $9.5 million at September 30, 2018 as compared to December 31, 2017, was primarily due to net cash used in operating activities of $10.6 million. The $10.6 million of net cash used in operating activities was primarily driven by the Company’s net loss of $14.6 million for the nine months ended September 30, 2018.

The following table summarizes our change in cash, cash equivalents and restricted cash (in thousands):

Net cash used in operating activities consists of our net loss, adjusted for our non-cash charges, plus or minus working capital changes. Cash used in operating activities for the nine months ended September 30, 2018 totaled $10.6 million and was primarily comprised of our net loss of $14.6 million, partially offset by non-cash adjustments for depreciation and amortization expenses of $0.7 million, provision for bad debts of $0.3 million and stock-based compensation expenses of $1.9 million. The $1.0 million net increase in our operating assets and liabilities was primarily due to a decrease in accounts payable and accrued liabilities of $3.2 million related to the timing of our payments, partially offset by an increase in inventory of $1.2 million resulting from lower than projected sales, an increase in accounts receivable of $1.6 million related to the timing of our collections and a decrease in deferred revenue of $0.4 million, resulting from the impact of implementing the new revenue recognition standard which provided for less deferred installation and deferred diode online training revenue.

Cash used in investing activities for the nine months ended September 30, 2018 consisted of $0.1 million of capital expenditures. The period-over-period decrease was primarily due to the timing of our capital expenditures.

Net cash provided by financing activities for the nine months ended September 30, 2018 of $1.2 million resulted primarily from net proceeds from our line of credit of $1.5 million, partially offset by payments of 2017 equity offering costs of $0.1 million and payments of debt issuance costs of $0.1 million.

The effect of exchange rate on cash for the nine months ended September 30, 2018 was minimal.

As of September 30, 2018, the Company had working capital of approximately $10.8 million. Our principal sources of liquidity as of September 30, 2018 consisted of approximately $2.4 million in cash, cash equivalents and restricted cash and $11.4 million of net accounts receivable.

On March 6, 2018, BIOLASE and two of its wholly-owned subsidiaries (such subsidiaries, collectively with BIOLASE, the “Borrower”) entered into a Business Financing Agreement (the “Original Business Financing Agreement”) with Western Alliance, which provided for borrowings of up to $6.0 million. On August 13, 2018, the Borrower and Western Alliance entered into a Business Financing Modification Agreement, pursuant to which Western Alliance waived the Borrower’s covenant defaults under the Original Business Financing Agreement and provided an advance of $1.5 million, which was due by September 27, 2018. On September 27, 2018, the Borrower and Western Alliance entered into a Business Financing Modification Agreement (the “Second Modification Agreement”), which reduced the credit limit under the Original Business Financing Agreement (as amended on August 13, 2018”) to $2.5 million and extended the due date of the $1.5 million advance to March 6, 2019. In addition, pursuant to the Second Modification Agreement, the Borrower agreed to deliver to Western Alliance a term sheet for an equity or debt financing for not less than $5 million in gross proceeds and agreed to close such financing on or before November 15, 2018. The Company had $1.5 million of borrowings outstanding under the Original Business Financing Agreement (as amended on August 13, 2018 and September 27, 2018, such agreement the “Business Financing Agreement”) as of September 30, 2018. See Part I, Item I, Note 9 – Lines of Credit for additional information.

On October 26, 2018, the Borrower and Western Alliance entered into a new Business Financing Modification Agreement, pursuant to which Western Alliance waived BIOLASE’s non-compliance with certain financial operating covenants as set forth in the Business Financing Agreement, and the Borrower agreed to certain amendments to covenants contained in the Business Financing Agreement. See Part I, Item I, Note 14 – Subsequent Event for additional information.

On November 9, 2018, BIOLASE entered into a five-year secured Credit Agreement with SWK, pursuant to which BIOLASE has borrowed $12.5 million. $0.9 million of the proceeds from the SWK Loan have been used to pay off all amounts owed to Western Alliance under the Business Financing Agreement (as amended on October 26, 2018), and the Company plans to use the remaining proceeds to provide additional working capital to fund its growth initiatives, such as broadening its customer base and increasing the utilization of its products to drive recurring higher margin consumables revenue. See Part I, Item I. Note 14 – Subsequent Event for additional information.

In order for us to continue operations beyond the next 12 months and be able to discharge our liabilities and commitments in the normal course of business, we must increase sales of our products directly to end-users and through distributors, establish profitable operations through the combination of increased sales and decreased expenses, generate cash from operations or obtain additional funds when needed. We intend to improve our financial condition and ultimately improve our financial results by increasing revenues through expansion of our product offerings, continuing to expand and develop our fields sales force and distribution relationships both domestically and internationally, forming strategic arrangements within the dental and medical industries, educating dental and medical patients as to the benefits of our advanced medical technologies, and reducing expenses. Additional capital requirements may depend on many factors, including, among other things, continued losses, the rate at which our business grows, demands for working capital, manufacturing capacity, and any acquisitions that we may pursue. From time to time, we could be required, or may otherwise attempt, to raise capital, through either equity or debt offerings, or enter into another line of credit facility. As discussed below, on November 9, 2018, BIOLASE entered into a new financing agreement. We cannot provide assurance that we will be able to successfully consummate any equity or debt financings or enter into any other line of credit facility 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 our stockholders.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this report (the “Evaluation Date”). Based on this evaluation, our principal executive officer and principal financial officer concluded as of the Evaluation Date that our disclosure controls and procedures were effective such that the information relating to the Company, including our consolidated subsidiaries, required to be disclosed in our SEC reports (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and (ii) is accumulated and communicated to the Company’s management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during our most recently completed fiscal quarter. Based on that evaluation, our principal executive officer and principal financial officer concluded that there has not been any change in our internal control over financial reporting during the quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

The disclosure contained in the first and second paragraphs of Part I, Item 1, Note 10 – Commitments and Contingencies—Litigation—Intellectual Property Litigation is hereby incorporated herein by reference.

Except for the following, there have been no material changes to the risk factors as disclosed in Part I, Item 1A “Risk Factors” in the 2017 Form 10-K.

Failure to meet covenants in the Credit Agreement, dated as of November 9, 2018 (the “Credit Agreement”), between BIOLASE, Inc. and SWK Funding LLC, as agent (“SWK”), could result in acceleration of our payment obligations thereunder, and we may not be able to find alternative financing.

Under the Credit Agreement, we are required to maintain a specified amount of consolidated unencumbered liquid assets as of the end of fiscal quarter, generate minimum levels of revenue as of the end of each period specified in the Credit Agreement and maintain specified levels of consolidated EBITDA as of the end of each period specified in the Credit Agreement. Our ability to comply with these covenants may be affected by factors beyond our control. If we fail to comply with the covenants contained in the Credit Agreement, or if the Required Lenders (as defined in the Credit Agreement) contend that we have failed to comply with these covenants or any other restrictions, it could result in an event of default under the Credit Agreement, which would permit or, in certain events, require SWK to declare all amounts outstanding thereunder to be immediately due and payable. There can be no assurances that we will be able to repay all such amounts or able to find alternative financing in an event of a default. Even if alternative financing is available in an event of a default under the Credit Agreement, it may be on unfavorable terms, and the interest rate charged on any new borrowings could be substantially higher than the interest rate under the Credit Agreement, thus adversely affecting our business, financial condition, and results of operations.

Our variable rate indebtedness under the Credit Agreement subjects us to interest rate risk, which could result in higher expense in the event of increases in interest rates and adversely affect our business, financial condition, and results of operations.

Borrowings under the Credit Agreement bear interest at a rate that varies depending on the London Interbank Offered Rate (“LIBOR”). As a result, we are exposed to interest rate risk. If LIBOR rises, the interest rate on outstanding borrowings under the Credit Agreement will increase. Therefore, an increase in LIBOR will increase our interest payment obligations under the Credit Agreement and have a negative effect on our cash flow and our business, financial condition, and results of operations.

The restrictive covenants in the Credit Agreement and the Company’s obligation to make debt payments under the Credit Agreement may limit our operating and financial flexibility and may adversely affect the Company’s business, financial condition, and results of operations.

The Credit Agreement imposes operating and financial restrictions and covenants, which may limit or prohibit our ability to, among other things:

In addition, we are required to comply with certain financial covenants under the Credit Agreement as described above.

Such restrictive covenants in the Credit Agreement and the Company’s repayment obligations under the Credit Agreement could have adverse consequences to the Company, including:

If we fail to comply with the terms of the Credit Agreement and there is an event of default, the creditor(s) may foreclose upon the assets securing our obligations thereunder.

To secure the performance of our obligations under the Credit Agreement, we granted SWK security interests in substantially all of the assets of BIOLASE and certain of our foreign and domestic subsidiaries. Our failure to comply with the terms of the Credit Agreement could result in an event of default thereunder. In that event, SWK

will have the option to (and, in certain circumstances, will have the obligation to) foreclose on the assets of BIOLASE and certain of our subsidiaries pledged as collateral under the Credit Agreement or the other documents executed in connection with the Credit Agreement. The foreclosure on the Company’s assets could severely and negatively impact our business, financial condition, and results of operations.

If certain individuals (or permitted replacements thereof) no longer serve as our Chairman, Chief Executive Officer or Chief Financial Officer, we may be obligated to pay all outstanding obligations and certain fees under the Credit Agreement.

The Credit Agreement provides that, unless such actions are consented to in advance in writing by SWK, if two or more of the three of Jonathan Lorde, Todd Norbe and Jonathan Beaver (or, in each case, his approved successor) at any one time no longer serves in their current positions with BIOLASE and we do not find individuals to replace such individuals within 150 days (or in certain circumstances 210 days), with individuals of appropriate qualification and experience approved in writing by SWK (which approval may not be unreasonably withheld or delayed), there is a “Key Person Event” and all outstanding obligations and certain fees under the Credit Agreement become immediately due and payable. Whether Mr. Lorde, Mr. Norbe and Mr. Beaver remain our Chairman, Chief Executive Officer and Chief Financial Officer, respectively, is not under our control. Although we intend to find an appropriate replacement satisfactory to SWK if any of Mr. Lorde, Mr. Norbe or Mr. Beaver leaves his current position, there is no assurance that we will be able find such a replacement within the time period permitted under the Credit Agreement, if at all. If there is a Key Person Event, there can be no assurance that we will be able to repay all outstanding obligations and fees payable or able to find alternative financing. Even if alternative financing is available, it may be on unfavorable terms, and the interest rate charged on any new borrowings could be substantially higher than the interest rate under the Credit Agreement, thus adversely affecting our business, financial condition, and results of operations.

The risks and uncertainties described in our 2017 Annual Report and above are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also materially adversely affect our business, financial condition or results or operations.

The information below is reported in lieu of information that would be reported under Items 1.01, 1.02 and 2.03 under Form 8-K.

BIOLASE entered into a Credit Agreement, dated as of November 9, 2018 (the “Credit Agreement”), with SWK Funding LLC, as agent and lender (“SWK”).

The Credit Agreement provides for a five-year $12.5 million term loan (“Term Loan”) that matures on November 9, 2023. The Credit Agreement also contemplates an additional $2.5 million subordinated facility, subject to an intercreditor agreement satisfactory to SWK in its commercially reasonable discretion.

BIOLASE’s obligations under the Credit Agreement are guaranteed by certain of BIOLASE’s foreign and domestic subsidiaries (such subsidiaries, together with BIOLASE, the “Loan Parties”) and are secured by a security interest in substantially all of the Loan Parties’ property, subject to certain exceptions.

The Term Loan bears interest at a floating rate based upon three-month LIBOR (but not less than 2.25% per year) plus 10.00%, payable on the 15th day of each of February, May, August and November, commencing on February 15, 2019. BIOLASE paid an origination fee (the “Origination Fee”) in the amount of $187,500 on November 9, 2018. Additionally, BIOLASE is required to pay an exit fee of $1.0 million (the “Exit Fee”) on the earlier to occur of November 9, 2023 or the date the obligations under the Credit Agreement are paid in full or become immediately due and payable.

Upon a “Change of Control” (as defined in the Credit Agreement) on or before November 9, 2019, BIOLASE is required to immediately prepay all outstanding obligations under the Credit Agreement and also pay a prepayment fee (the “COC Prepayment Fee”), calculated as the additional amount that would be needed such that the sum of such fee, plus the principal payments made by BIOLASE (including the Origination Fee), plus without duplication, all Revenue-Based Payments (as defined in the Credit Agreement) actually made in cash (excluding, any amounts paid in respect of costs, expenses, indemnifications or reimbursements or any amounts paid in connection with the SWK Warrants (as defined below), but including any amounts paid on account of the Origination Fee, the prepayment fee and the Exit Fee) results in an amount equal to $15,375,000. A Change of Control is defined under the Credit Agreement to include, in addition to other customary change of control events, a Key Person Event. Unless such actions are consented to in advance in writing by SWK, a Key Person Event occurs if two or more of the three of Jonathan Lorde, Todd Norbe and Jonathan Beaver (or, in each case, his approved successor) at any one time no longer serves in their current positions with BIOLASE and BIOLASE does not find individuals to replace such individuals within 150 days (or in certain circumstances 210 days), with individuals of appropriate qualification and experience approved in writing by SWK (which approval may not be unreasonably withheld or delayed).

The Credit Agreement provides for certain mandatory prepayment fees in connection with certain dispositions. Voluntary prepayments may be made in whole but not in part at any time after November 9, 2019. However, for any such prepayment made on or after November 9, 2019 but prior to November 9, 2020, there is a prepayment fee equal to 6% of the aggregate amount of the Term Loan so prepaid, and for any such prepayment made on or after November 9, 2020 but prior to November 9, 2021, there is a prepayment fee equal to 1% of the aggregate amount of the Term Loan so prepaid. There is no prepayment fee payable on voluntary prepayments made on or after November 9, 2021.

On each payment date, BIOLASE is obligated to pay an amount based on a percentage of the aggregate of the net sales, royalties and other revenue realized by BIOLASE and/or its subsidiaries on a consolidated basis in accordance with U.S. generally accepted accounting principles. As set forth in the Credit Agreement, commencing with the fiscal quarter beginning January 1, 2018, the Revenue-Based Payment with respect to each fiscal quarter is equal to (i) 50.00% of Aggregate Revenue (as defined in the Credit Agreement) during the period commencing as of January 1 of the fiscal year of which such fiscal quarter is part, through the end of such fiscal quarter (such elapsed portion of the fiscal year, the “Elapsed Period”) up to and including $7,500,000 plus (ii) 25.00% of Aggregate Revenue during the Elapsed Period greater than $7,500,000 minus (iii) the aggregate amount of Revenue-Based Payments, if any, made with respect to prior fiscal quarters in such fiscal year.

The Credit Agreement also includes three financial covenants. First, BIOLASE may not permit the Consolidated Unencumbered Liquid Assets (as defined in the Credit Agreement) as of the last day of any fiscal quarter to be less than the greater of (i) $1,500,000 or (ii) the Operating Burn (as defined in the Credit Agreement). Second, BIOLASE may not permit the Aggregate Revenue as of the end of each fiscal quarter to be less than the amount set forth in the Credit Agreement. Third, BIOLASE may not permit consolidated EBITDA as of the end of each fiscal quarter to be less than the amount set forth in the Credit Agreement.

The Credit Agreement also contains customary events of default and other covenants, including certain restrictions on BIOLASE’s or the Loan Parties’, as applicable, ability to incur additional indebtedness, create liens, consolidate or merge, enter into acquisitions, pay any dividend or distribution on BIOLASE’s stock, redeem, retire or purchase shares of BIOLASE’s stock, make investments or pledge or transfer assets. If an event of default under the Credit Agreement occurs and is continuing, then any outstanding obligations under the Credit Agreement may be declared immediately due and payable. In addition, if BIOLASE becomes the subject of voluntary or involuntary proceedings under any bankruptcy or similar law, then any outstanding obligations under the Credit Agreement will automatically become immediately due and payable.

On November 9, 2018, in connection with the Credit Agreement, BIOLASE issued to SWK or its assignees (collectively with SWK, the “Holder”) warrants (the “SWK Warrants”) to purchase up to 372,023 shares of BIOLASE common stock. The exercise price of the SWK Warrants is $1.34 per share, which was the average closing price of BIOLASE common stock for the ten trading days immediately preceding November 9, 2018. The SWK Warrants are immediately exercisable, expire on November 9, 2026 and contain a “cashless exercise feature.” Subject to certain limitations, the Holder has certain piggyback registration rights with respect to the shares that are issued upon exercise of the SWK Warrants.

The description of the Credit Agreement and the SWK Warrants set forth above are qualified in their entirety by reference to the Credit Agreement and Warrant filed as Exhibit 10.6 and Exhibit 4.2, respectively, to this Quarterly Report on Form 10-Q, which exhibits are hereby incorporated herein by reference.

On November 9, 2018, the Business Financing Agreement, dated as of March 6, 2018 and as amended on August 13, 2018, September 27, 2018 and October 26, 2018 (the “Existing Credit Agreement”), among BIOLASE, BL Acquisition Corp. and BL Acquisition II Inc., as borrowers, and Western Alliance Bank, an Arizona corporation, as lender, was replaced by the Credit Agreement. All outstanding borrowings, accrued interest and fees under the Existing Credit Agreement were paid off with a portion of the proceeds under the Credit Agreement, and the Existing Credit Agreement was terminated.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
