NOTE 7 — COMMITMENTS AND CONTINGENCIES

Leases

The Company enters into operating leases primarily for real estate, office equipment, and fleet vehicles. Lease terms generally range from one to five years, and often include options to renew for one year. The Company leases its corporate headquarters pursuant to a lease that expires on December 31, 2025 and leases a manufacturing facility located in Corona, California, which expires on June 30, 2025. The Company also leases additional office space and certain office equipment under various operating lease arrangements.

On January 1, 2019, the Company adopted Leases (Topic 842), using the modified-retrospective approach. Because the rate implicit in each lease is not readily determinable, the Company uses its incremental borrowing rate (“IBR”) to determine the present value of the lease payments.

On January 22, 2020, the Company entered into a five-year real property lease agreement for an approximately 11,000 square foot facility in Corona, California and moved its manufacturing operations. The lease commenced on July 1, 2020. On December 10, 2021, the Company entered a lease for an additional 15,000 square feet at its facility in Corona, California. This additional lease commenced on February 1, 2022 and ends on June 30, 2025.

On February 4, 2020, the Company also entered into a 66-month real property lease agreement for office space of approximately 12,000 square feet of office space in Lake Forest, California. The lease commenced on July 1, 2020.

Lease expense consists of payments for real property, office copiers, and IT equipment. The Company recognizes payments for non-lease components such as common area maintenance in the period incurred. As of December 31, 2021, the only lease that had not commenced was for the additional facility lease in Corona, California.

Rent expense totaled $0.9 million, $0.7 million and $0.8 million in each of the years ended December 31, 2021, 2020, and 2019, respectively.

Employee Arrangements and Other Compensation

Certain members of management are entitled to severance benefits payable upon termination following a change in control, which would approximate $2.3 million and $2.0 million at December 31, 2021 and 2020, respectively. The Company also has agreements with certain employees to pay bonuses based on targeted performance criteria. As of December 31, 2021 and 2020, $0.4 million and $0.8 million was accrued for performance bonuses, which is included in accrued liabilities in the consolidated balance sheets. See Note 8 – Redeemable Preferred Stock and Stockholders’ Equity for additional information relating to specific stock-based compensation awards.

Purchase Commitments

The Company generally purchases components and subassemblies for its products from a limited group of third-party suppliers through purchase orders. The Company had $18.7 million of purchase commitments as of December 31, 2021, for which the Company has not received the goods or services and which is expected to be purchased primarily 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.

Litigation

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.

Intellectual Property Litigation

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 stemmed from a press release that BIOLASE issued on April 30, 2012, which CAO claimed contained false statements that were disparaging to CAO and its diode product. The amended complaint sought 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, which were generally favorable to the Company. 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.

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 sought injunctive relief, treble damages, attorneys’ fees, punitive damages, and interest.

On January 25, 2019 (the “Effective Date”), BIOLASE entered into a settlement agreement (the “Settlement Agreement”) with CAO. Pursuant to the Settlement Agreement, CAO agreed to dismiss with prejudice the lawsuits filed by CAO against the Company in April 2012 and January 2018. In addition, CAO granted to the Company and its affiliates a non-exclusive, non-transferable (except as provided in the Settlement Agreement), royalty-free, fully-paid, worldwide license to the licensed patents for use in the licensed products and agreed not to sue the Company, its affiliates or any of its manufacturers, distributors, suppliers or customers for use of the licensed patents in the licensed products, and the parties agreed to a mutual release of claims. The Company agreed (i) to pay to CAO, within five days of the Effective Date, $500,000 in cash, (ii) to issue to CAO, within 30 days of the Effective Date, 500,000 restricted shares of BIOLASE common stock (the “Stock Consideration”), and (iii) to pay to CAO, within 30 days of December 31, 2021, an amount in cash equal to the difference (if positive) between $1,000,000 and the value of the Stock Consideration as of December 31, 2021. The Stock Consideration vests on December 31, 2021, the measurement date, and is payable in January 2021, subject to the terms of a restricted stock agreement to be entered into between the parties. The Company recognized a $1.5 million contingent loss on patent litigation settlement in its statement of operations for the year ended December 31, 2018. In January 2019, the Company paid CAO $500,000 in cash. On January 31, 2019, the case was dismissed with prejudice. During the three-month period ended March 31, 2019, the Company recorded an additional loss on patent litigation of $0.2 million which represented the change in fair value of the restricted stock to be issued to CAO at March 31, 2019. Subsequent to March 31, 2019, the Company reversed the additional loss commensurate with the fluctuations in the Company’s share price. In August 2020, the Company signed a Letter Agreement to terminate the Manufacturing Agreement and purchase from CAO raw materials and other inventory held by CAO as part of the original Settlement Agreement. During the year ended December 31, 2021, the Company recorded an additional loss on patent litigation of $0.3 million which represented the change in fair value of the liability to be paid to CAO.

In February 2021, the Company issued 500,000 restricted shares of common stock in satisfaction of its obligation to issue the Stock Consideration to CAO under the Settlement Agreement and reduced the accrued liability to $0.6 million. As of December 31, 2021, the remaining accrued liability related to the Settlement Agreement was included in current accrued liabilities in the amount of $0.8 million. As of December 31, 2020, the accrued liability related to the Settlement Agreement was $1.0 million and was included in non-current other liabilities. In January 2022, the Company paid all amounts due to CAO and removed the liability.
