NOTE 7 — COMMITMENTS AND CONTINGENCIES

Leases

In January 2006, the Company entered into a five-year lease for its 57,000 square foot corporate headquarters and manufacturing facility located at 4 Cromwell, Irvine, California, with initial monthly installments of $38,692 and annual adjustments over the lease term. On September 24, 2009, the lease was amended to extend the term through April 20, 2015, adjust the basic rent, and modify provisions to the security deposit. On January 4, 2011, the lease was further amended to defer a portion of the basic rent to future periods. The Company is recognizing rent expense on a straight line basis with the difference between rent expense and the cash paid recorded to deferred rent. These amounts are reflected in the commitments as of December 31, 2013, listed below. The Company also leases certain office equipment and automobiles under various operating lease arrangements.

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

2014	$	697
2015		204
2016		—
2017		—
Thereafter		—
Total future minimum lease obligations	$	901

Rent expense totaled approximately $1.1 million, $789,000, and $1.0 million for the years ended December 31, 2013, 2012, and 2011, 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 $717,000 at December 31, 2013. The Company also has agreements with certain employees to pay bonuses based on targeted performance criteria. No amount was required to be accrued at December 31, 2013 and 2012.

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 $11.4 million of purchase commitments as of December 31, 2013, 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.

Class Action Lawsuits

On August 23, 2013, a purported class action lawsuit entitled Brady Adams v. Biolase, Inc., et al., Case No. 13-CV-1300 JST (FFMx) was filed in the United States District Court for the Central District of California against BIOLASE and its current executive officers Federico Pignatelli and Frederick D. Furry. On August 26, 2013, a purported class action lawsuit entitled Ralph Divizio v. Biolase, Inc., et al., Case No. 13-CV-1317 DMG (MRWx) was filed in the same court against BIOLASE, Messrs. Pignatelli and Furry, and current executive officer Alexander K. Arrow. Each of the lawsuits alleges violations of the federal securities laws and asserts causes of action against the defendants under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. In accordance with the Private Securities Litigation Reform Act of 1995, on December 10, 2013, the court entered an order consolidating the lawsuits, appointing a lead plaintiff and approving lead plaintiff's selection of lead counsel. On February 24, 2014, lead plaintiff filed a consolidated complaint against BIOLASE and Messrs. Pignatelli, Furry, and Arrow, alleging violations of the federal securities laws and asserting causes of action against the defendants under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934.

On November 19, 2013, BIOLASE’s Board received a letter from attorneys for purported shareholder David T. Long, demanding that the Board investigate, institute litigation, and take measures to redress and prevent alleged wrongdoing concerning the dissemination of certain allegedly false and misleading public disclosures made by the Company between January 2013 and August 2013.

As of December 31, 2013, the Company paid $250,000 for legal costs expected to be incurred in connection with these matters. The Company believes that the claims contained in the lawsuits are without merit and intends to vigorously defend against the claims.

Intellectual Property Litigation

On April 24, 2012, CAO Group, Inc. (“CAO”) filed a lawsuit against the Company in the District of Utah for patent infringement of U.S. Patent No. 7,485,116 regarding the Company’s EZlase dental laser. On September 9, 2012, CAO filed its First Amended Complaint, which added 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 the Company issued on April 30, 2012, which CAO claims contained false statements that are disparaging to CAO and its diode product. The First Amended Complaint seeks injunctive relief, treble damages, attorneys’ fees, punitive damages, and interest. On November 13, 2012, the Court stayed the lawsuit for 120 days to allow the United States Patent and Trademark Office (“USPTO”) to consider the Company’s request for reexamination of the patent-in-suit. The USPTO granted the request to reexamine the asserted claims of the patent-in-suit and, on February 28, 2013, the Court stayed the lawsuit until the termination of the reexamination proceedings. On April 23, 2013, the USPTO issued an office action rejecting all of the asserted claims over the prior art, and CAO responded to the office action. On August 28, 2013, the USPTO issued an Action Closing Procedure, rejecting all of CAO’s patent claims. CAO responded to the USPTO’s ruling and on December 10, 2013, the USPTO issued a Right of Appeal Notice, finally rejecting some claims of the patent while finding that other claims appeared to be patentable. Both parties are permitted to appeal the USPTO’s findings to the Patent Trial and Appeal Board. The Company appealed the USPTO’s findings on January 9, 2014. On January 27, 2014, the USPTO declined to reconsider the finding of certain claims as patentable and instructed the parties to proceed to appeal to the Patent Trial and Appeal Board.

The Company filed a patent infringement lawsuit against Fotona dd. (“Fotona”) in Düsseldorf District Court alleging infringement with respect to the Fotona Fidelis dental laser system. Oral proceedings are currently scheduled for March 2014. Fotona denies liability and seeks the reimbursement of statutory fees from the Company. Together with its response brief, Fotona also filed a nullity action against the patent in dispute, patent number EP 1 560 470. The nullity action is pending at the German Federal Patent Court (the “Patent Court”), Docket No. 1 Ni 58/13 (EP). On September 2, 2013, the Company filed its counterplea in the infringement proceedings and phrased its arguments defending the validity of the patent. These arguments were also the subject of the defense brief to the Patent Court in the parallel nullity action proceedings. On September 9, 2013, the Company filed its response to the Patent Court. Fotona filed a rejoinder on February 3, 2014, including its counterplea on nullity.

False Advertising Lawsuit

The Company filed a false advertising lawsuit against Fotona and Technology4Medicine L.L.C., two of its competitors (together "the Defendants") in United States District Court for the Central District of California. The lawsuit alleges six causes of action, and claims that the Defendants have made false and misleading statements regarding the Company's products, technology, and management. The lawsuit, filed on February 20, 2014, seeks both cash damages and injunctive relief.

Other Matters

In the normal course of business, the Company may be subject to other legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of probable monetary liability or financial impact with respect to these matters is subject to many uncertainties and is therefore not predictable with assurance, the Company’s management believes that any monetary liability or financial impact to the Company from these other matters, individually and in the aggregate, would not be material to the Company’s financial condition, results of operations or cash flows. However, there can be no assurance with respect to such result, and monetary liability or financial impact to the Company from these other matters could differ materially from those projected.
