EXPLANATORY NOTE

This Amendment No. 1 to Form 10-K (this Amendment) amends the Annual Report on Form 10-K for the fiscal year ended
December 31, 2013 (the Original Filing), originally filed with the Securities and Exchange Commission (the SEC) on March 17, 2014, of Biolase, Inc. Because we do not expect to file our definitive proxy statement
within 120 days of the end of our fiscal year ended December 31, 2013, we are filing this Amendment to provide the information required by Items 10, 11, 12, 13 and 14 of Part III of the SECs Form 10-K and not included
in the Original Filing.

As required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended, this Amendment includes as exhibits the
certifications required of our principal executive officer and principal financial officer under Section 302 of the Sarbanes-Oxley Act of 2002. We have included Part IV, Item 15 in this Amendment solely to reflect the filing of these
exhibits with this Amendment. We are not including certifications under Section 906 of the Sarbanes-Oxley Act of 2002 as no financial statements are being filed with this Amendment.

No attempt has been made with this Amendment to modify or update the other disclosures presented in the Original Filing, including the exhibits thereto,
except that we have updated the number of outstanding shares of our common stock on the cover page of this Amendment. The Original Filing continues to speak as of the date of the Original Filing, and we have not updated the disclosures contained
therein to reflect any events which occurred at a date subsequent to the filing of the Original Filing. Accordingly, this Amendment should be read in conjunction with the Original Filing and our other filings made with the SEC.

Unless otherwise noted or as the context otherwise requires, the terms the Company, we, us, or our refer to
Biolase, Inc.

dividend yield of 0%.

The grant date fair value for the June 7, 2013 option grants to Dr. Moll and Ms. Enright was $2.17,
which was determined using the Black-Scholes option valuation model with the following assumptions: market price of $4.07, exercise price of $4.07, expected volatility of 75.3%, risk free interest rate of 1.10%, expected option life of 3.6 years,
and an expected dividend yield of 0%.

The grant date fair value for the June 6, 2013 option grants to Dr. Nemoy and
Mr. Lichtwardt was $2.13, which was determined using the Black-Scholes option valuation model with the following assumptions: market price of $4.00, exercise price of $4.00, expected volatility of 75.3%, risk free interest rate of 1.01%,

Individuals who are appointed or elected
to our Board as a non-employee director at an annual meeting of stockholders are granted an option to purchase 20,000 shares of our common stock. In addition, the Board modified the calculation for options granted automatically to newly
appointed non-employee directors to the number of shares equal to the sum of (a) 20,000 and (b) the product of (i) 1,250 and (ii) one plus the number of whole calendar months that will have elapsed between the date of appointment
to the Board and the anticipated date of the next annual meeting of stockholders.

##### Table of Contents

Each annual option grant vests over one year in equal quarterly increments, with the first
vesting date occurring three months after the date of grant, except in the case of initial option grants for non-employee directors, which vest in monthly installments upon the non-employee directors completion of each month of service as a
non-employee director measured from the option grant date. Vesting is accelerated in full if certain changes in control or ownership occur or if the optionee dies or becomes disabled while serving as a director. Each option has an exercise price per
share equal to the closing sale price of our common stock on the date of grant and has a maximum term of ten years, subject to earlier termination on the first anniversary of the directors cessation of our Board service for any reason. Each
automatic option is immediately exercisable for all of the option shares and the director would receive unvested shares for each unvested option exercised. However, any unvested shares are subject to repurchase by us, at the lower of the exercise
price paid per share or the fair market value per share (determined at the time of repurchase), should the director cease Board service prior to vesting of those shares.

The following table sets forth the number of shares underlying outstanding stock options (vested and unvested) held by each of our current and
former non-employee directors as of December 31, 2013. Our directors did not hold any unvested shares of restricted stock as of December 31, 2013.

The executive officers are appointed by our Board on an annual basis and serve at the discretion of our Board,
subject to the terms of any employment agreement with us, until their earlier resignation or removal. There are no family relationships among any of the directors or executive officers. The following is a brief description of the present and past
business experience of Dr. Arrow and Mr. Furry. The biography of Mr. Pignatelli appears earlier under Our Directors.

Alexander K. Arrow,M.D., CFA, 43, was appointed to the Board in July 2010 and became the President and Chief Operating Officer in June
2013. From July 2012 to June 2013 Dr. Arrow was the Chief Medical and Strategic Officer of Circuit Therapeutics, Inc., a company seeking to realize commercial potential in the field of optogenetics. Previously, Dr. Arrow was the Chief
Financial Officer of Arstasis, Inc., a 115-employee cardiology device manufacturer. From 2002 to 2007, Dr. Arrow headed medical technology equity research at the global

investment bank Lazard, providing research coverage on a wide variety of medical device manufacturers. Dr. Arrow also spent two years as Chief Financial Officer of the Patent &
License Exchange, later renamed PLX Systems, Inc., and three years as the publishing life sciences research analyst at Wedbush Morgan Securities. In 1996, Dr. Arrow was a surgical resident at the UCLA Medical Center. Dr. Arrow received his
CFA in 1999. He was awarded an M.D. from Harvard Medical School in 1996 and a B.A. in Biophysics, magna cum laude, from Cornell University in 1992.

Frederick D. Furry,46, has served as our Chief Financial Officer since November 2010 and served as our Chief Operating Officer
from October 2011 to June 2013. Mr. Furry is a certified public accountant (inactive) and has 18 years of experience working with manufacturing and high technology companies with public accounting firms, including PricewaterhouseCoopers LLP.
From July 2004 to December 2009, Mr. Furry served as an audit partner at Windes, Inc. He holds an M.B.A. from the A. Gary Anderson Graduate School of Management at the University of California, Riverside.

Section 16(a) Beneficial Ownership Reporting Compliance

The members of our Board, executive officers, and beneficial holders of more than ten percent of the outstanding shares of our common stock are
subject to the reporting requirements of Section 16(a) of the Securities Exchange Act of 1934 which requires them to file reports with respect to their ownership of our securities. To our knowledge, based solely upon the copies of
Section 16(a) reports which we received from such persons for their 2013 fiscal year transactions in our common stock and their common stock holdings, we believe that all reporting requirements under Section 16(a) for such fiscal year were
met in a timely manner by our directors, executive officers, and greater than ten percent beneficial owners.

Code of Business Conduct and Ethics

We have adopted a Code of Business Conduct and Ethics. This code of ethics applies to our directors, executive officers and employees.
This code of ethics is publicly available in the corporate governance section of the stockholder relations page of our website located at http://www.biolase.com/Pages/Investors and in print upon request to the Secretary at Biolase, Inc., 4
Cromwell, Irvine, California, 92618. If we make amendments to the code of ethics or grant any waiver that we are required us to disclose, we will disclose the nature of such amendment or waiver on our website.

Audit Committee and Financial Expert

Audit Committee of the Board of Directors consists of three directors, all of whom are independent pursuant to the rules of the NASDAQ Stock Market and other SEC rules and regulations applicable to audit committees. The following directors are
currently members of the Audit Committee: James R. Talevich, who serves as the chairman, Norman J. Nemoy, and Frederic H. Moll. The Board of Directors has determined that James R. Talevich qualifies as an audit committee financial expert, as such

Compensation Discussion and Analysis

This compensation discussion and analysis section discusses the compensation policies and programs for our named executive
officers, which consist of: Federico Pignatelli, our Chairman of the Board and Chief Executive Officer, effective September 30, 2010; Alexander K. Arrow, M.D., our President and Chief Operating Officer, effective June 6, 2013; Frederick D.
Furry, our Chief Financial Officer, effective November 30, 2010; and Michael Stevens, Director of Professional Relations and a Territory Sales Manager. The Compensation Committee of our Board of Directors is primarily responsible for overseeing
the development and administration of the total compensation program for corporate officers and key executives, and administering our executive incentive bonus and stock plans.

##### Table of Contents

Compensation Objectives.

It is important that we employ energetic people who are enthusiastic about our mission and our products, and we believe this must start at the
top with our executive officers who set an example for the entire company. We are engaged in a very competitive industry, and our success depends upon our ability to attract and retain qualified executive officers by offering them competitive
compensation packages. Our compensation programs for our executive officers are designed to attract and retain such key executive officers, and to reward them in a fashion commensurate with our corporate performance and the value created for our
stockholders. Our compensation programs also support our short-term and long-term strategic goals and values and reward the individual contributions of our executive officers to our success.

Our policy is to provide our executive officers with competitive compensation opportunities that reward their contribution to our financial
success and individual performance, while providing financial stability and security. Accordingly, the compensation package for executive officers is mainly comprised of the following compensation elements: (1) a base salary, designed to be
competitive with salary levels in the industry and to reflect individual performance; (2) an annual discretionary bonus payable in cash and based on the review of certain annual financial and other performance measures, which supports our
short-term performance; (3) where appropriate, long-term stock-based incentive awards, which support our long-term performance and are designed to strengthen the mutual interests between our executive officers and our stockholders; and
(4) in some cases severance payments and other benefits payable upon termination of an officers employment by us without cause or by our officer for good reason, including following a change of control of us, which promotes executive
retention and efforts toward the best interests of the stockholders in the event of an actual or threatened change of control of us. We believe that each of these elements and their combination supports our overall compensation objectives.

Determination of Compensation Awards.

The Compensation Committee determines the compensation to be paid to our executive officers. The Compensation Committee periodically reviews
the total compensation levels and the distribution of compensation among the compensation elements identified above for each of our executive officers. The Compensation Committee determines the total compensation levels for our executive officers by
considering each executive officers position and responsibilities, the individuals performance of his job-related duties and responsibilities and our financial performance, in the context of our compensation policies and objectives and
competitive market data applicable to each executive officers position. Our approach is to consider competitive compensation practices as a relevant factor rather than establishing compensation at specific benchmark percentiles. This enables
us to respond to dynamics in the labor market and provides us with flexibility in maintaining and enhancing our executive officers engagement, focus, motivation and enthusiasm for our future.

The principal factors that were taken into account in establishing each executive officers compensation package for 2013 are described
below. The Compensation Committee may in its discretion apply entirely different factors, such as different measures of financial performance, for future years.

In addition, the Compensation Committee periodically reviews peer group data. The Compensation Committee believes that our most direct
competitors for executive talent include significantly larger and better-capitalized companies in the medical device industry, comprising a broader range of companies than those with which we usually are compared for purposes of stock performance.

Components of Compensation.

During the 2013 fiscal year, our executive officers compensation was composed of base salary, annual incentive bonuses, equity
compensation, certain perquisites, and, in one case, a potential severance payment payable upon certain events, including a qualifying termination of the executive officers employment subsequent to a change of control of the Company.

##### Table of Contents

The Compensation Committee monitors the results of the annual advisory say-on-pay
proposal and incorporates such results as one of many factors considered in connection with the discharge of its responsibilities, although no such factor is assigned a quantitative weighting. Because a substantial majority of our stockholders
approved the compensation program described in our proxy statement in 2013, the Compensation Committee did not implement changes to our executive compensation program as a result of the stockholder advisory vote.

Base Salaries.

Our executive officers base salaries are assessed annually by the Compensation Committee, taking into account each officers
position and responsibilities, including accomplishments and contributions, experience and tenure. In addition, the Compensation Committee considered the stockholders previous approval, on an advisory basis, the compensation of the
Companys named executive officers, as well as the Companys recent performance and current market conditions.

Mr. Pignatelli.In August 2010 Mr. Pignatelli was appointed to the position of Interim Chief Executive Officer at an
annual salary of $1.00. Mr. Pignatelli was appointed our permanent Chief Executive Officer on September 30, 2010 and has agreed to continue at a symbolic annual cash salary of $1.00 since that time.

Dr. Arrow. Dr. Arrows current annual base salary was set, at the time of his hire as our President and Chief
Operating Officer on June 6, 2013, at $250,000. His base salary was negotiated and was based on comparable market data, and our compensation goals and objectives.

Mr. Furry. Mr. Furrys current annual base salary was increased from $195,000 to $220,000 on December 14,
2013. His base salary was negotiated and was based on comparable market data, and our compensation goals and objectives.

Mr. Stevens.Mr. Stevens is our Director of Professional Relations and a Territory Sales Manager and his current base
salary is $90,000. His base salary was negotiated and was based on comparable market data, and our sales compensation goals and objectives.

Annual Bonuses.

Our annual bonuses have been historically intended to reward accomplishment of our overall short-term corporate performance and objectives for
a fiscal year.

Mr. Pignatelli.No formal annual bonus opportunity was set for Mr. Pignatelli in 2011, 2012, or
2013.

Dr. Arrow. Dr. Arrow joined us in June 2013 as President and Chief Operating Officer and is eligible to receive a
bonus based upon achieving certain financial and operational metrics as may be established from time to time by the Compensation Committee. No bonus was paid to, or accrued for, Dr. Arrow for the year ended December 31, 2013.

Mr. Furry. No formal annual bonus opportunity was set for Mr. Furry in 2011, 2012, or 2013. Mr. Furry received a
discretionary bonus of $10,000 in May 2013.

Mr. Stevens.No formal annual bonus opportunity was set for Mr. Stevens
in 2011, 2012, or 2013.

Stock-Based Incentive Awards.

Stock-based incentives are designed to align the interests of our executive officers with those of our stockholders and provide each individual
with a significant incentive to manage us from the perspective of an owner with an equity stake in the business. Stock options allow the officers to acquire shares of our common



8

##### Table of Contents

stock at a fixed price per share (which is at least the closing sale price of our stock on the grant date) over a specified period of time. Stock options generally become exercisable in a series
of installments over either a three- or four-year period, contingent upon the officers continued employment with us. Accordingly, stock options provide a return to the executive officer only if he remains employed by us during the vesting
period, and then only if the market price of the shares appreciates over the option term. As such, stock options not only reward our corporate performance but are also a key retention tool. The size of the option grant to each executive officer,
including any grant considered for the Chief Executive Officer and our other named executive officers, is set at a level that is intended to create a meaningful opportunity for stock ownership based on the individuals current position with us,
the individuals performance of his job related duties and responsibilities in recent periods and his or her potential for future responsibility and promotion over the option term. The Compensation Committee also takes into account the number
of unvested options held by the executive officer in order to maintain an appropriate level of equity incentive for that individual. The relevant weight given to each of these factors varies from individual to individual.

Mr. Pignatelli.Options to acquire 35,000 shares of our common stock at an exercise price of $5.34 and 100,000 shares of our
common stock at an exercise price of $2.58 were granted to Mr. Pignatelli in May 2011 and December 2011, respectively, in his capacity as an officer of the Company. The May 2011 stock option vested and became exercisable immediately. The
December stock option originally was to vest and become exercisable over forty-eight equal monthly installments commencing December 23, 2011, subject to Mr. Pignatellis continued employment with us. In March 2012, the unvested shares
were accelerated and subsequently exercised for cash. On November 8, 2012, Mr. Pignatelli was granted stock options to acquire 100,000 shares at an exercise price of $2.50, which options vest and become exercisable over twelve equal
monthly installments commencing November 8, 2012. The Compensation Committee considered these grants as necessary and appropriate for Mr. Pignatellis services. No options were granted to Mr. Pignatelli in 2013.

Dr. Arrow. At the time of his hire on June 6, 2013, Dr. Arrow was granted options to acquire 350,000 shares of our
common stock at an exercise price of $4.00 per share. The June 2013 option shall vest and be exercisable over 16 equal quarterly installments beginning on June 6, 2014, subject to Dr. Arrows continued employment with us. The June
2013 option has a seven year life and contains certain change in control language. The Compensation Committee considered this grant as necessary and appropriate for Dr. Arrows services.

Mr. Furry. Options to acquire 47,500 shares of our common stock at an exercise price of $2.58 were granted to Mr. Furry
in December 2011 and options to acquire 50,000 shares of our common stock at an exercise price of $5.00 were granted to Mr. Furry in March 2013. The December 2011 stock option vests and becomes exercisable over forty-eight equal monthly
installments commencing December 23, 2011 and the March 2013 stock option vests and becomes exercisable over forty-eight equal monthly installments commencing March 23, 2013, both subject to Mr. Furrys continued employment with
us. The Compensation Committee considered these grants as necessary and appropriate for Mr. Furrys services. No options were granted to Mr. Furry in 2012.

Mr. Stevens. No options were granted to Mr. Stevens in 2011, 2012, or 2013.

Policies with Respect to Equity Compensation Award Determinations.

We do not time the award of stock option grants in advance of material announcements in order to achieve lower exercise prices. In the past, we
have not granted any equity compensation awards other than stock options. Our policy is that stock options are granted with an exercise price equal to or greater than the closing price of our common stock on the date of grant, and that all option
grants are approved in advance of or on the date of the grant. The Secondary Stock Option Committee (consisting of our Chief Executive Officer and Chief Financial Officer) is delegated authority by the Board to approve stock option grants in an
amount not to exceed 12,000 shares per person and only for newly-hired employees. For stock option grants to new employees, our policy is that they be issued on, and receive an exercise price equal to or greater than the closing stock price of our
common stock on such employees start date, presuming that the award was pre-approved by the Secondary Stock Option Committee.

Perquisites and Other Benefits.

The Compensation Committee does not generally provide any perquisites at this time, except for a car allowance that is provided to
Mr. Stevens in connection with his Territory Sales Manager role.

Severance and Change of Control Arrangements.

Messrs. Pignatelli, Furry, and Stevens and Dr. Arrow are employed by the Company on an at will basis, and they do not have any
employment agreements or severance provisions. Certain of Dr. Arrows options immediately vest and become exercisable in the event of a change in control of the Company. Messrs. Pignatelli, Furry, and Stevens do not have any change in
control agreements with the Company.

Compliance with Internal Revenue Code Section 162(m).

Section 162(m) of the Internal Revenue Code disallows a tax deduction to publicly held companies for compensation paid to certain of their
executive officers to the extent that such compensation exceeds $1.0 million per covered officer in any fiscal year. The limitation applies only to compensation that is not considered to be performance-based. Nonperformance-based compensation
paid to our executive officers for the 2013 fiscal year did not exceed the $1.0 million limit per officer, and we do not expect the nonperformance-based compensation to be paid to our executive officers for the 2014 fiscal year to exceed that
limit. Our option grants under our 2002 Stock Incentive Plan have been designed to qualify as performance- based compensation.

There are
certain circumstances under which the Board and Compensation Committee may decide to exceed the deductibility limit imposed under Section 162(m) or to otherwise pay non-deductible compensation. These circumstances may include maintaining a
competitive salary for a named executive officer position or attracting highly qualified executives to join us and to promote their retention with compensation that is not performance based as part of their initial employment offers. Because it is
unlikely that the cash compensation payable to any of our executive officers in the foreseeable future will approach the $1.0 million limit, we do not expect to take any action to limit or restructure the elements of cash compensation payable
to our executive officers so as to qualify that compensation as performance-based compensation under Section 162(m). We will reconsider this decision should the individual cash compensation of any executive officer ever approach the
$1.0 million level.

Sections 280G and 4999 of the Internal Revenue Code impose certain adverse tax consequences on compensation
treated as excess parachute payments. An executive is treated as having received excess parachute payments for purposes of Sections 280G and 4999 of the Internal Revenue Code if he or she receives compensatory payments or benefits that are
contingent on a change in the ownership or control of a corporation, and the aggregate amount of such contingent compensatory payments and benefits equals or exceeds three times the executives base salary amount. An executives excess
parachute payments are subject to a 20% excise tax under Section 4999 of the Internal Revenue Code, in addition to any applicable federal income and employment taxes. Also, the corporations compensation deduction in respect of the
executives excess parachute payments is disallowed under Section 280G of the Internal Revenue Code. If we were to be subject to a change in control, certain amounts received by our executives could be excess parachute payments under
Sections 280G and 4999 of the Internal Revenue Code. As discussed under Potential Payments Upon Termination or Change in Control we do not provide our executive officers with tax gross up payments in the event of a change in
control.

|Item 13. | Certain Relationships and Related Transactions, and Director Independence
|-------- | -------------------------------------------------------------------------

The charter of the Audit Committee requires that it review any insider and related party transactions. In connection with this requirement, all
related party transactions (transactions involving our directors, executive officers or any member of their immediate family, or holder of more than five percent of our outstanding common stock) are disclosed and reviewed by our Audit Committee and
our Board of Directors at least annually. In addition, transactions involving our directors are disclosed and reviewed by the Nominating and Corporate Governance Committee in its assessment of our directors independence requirements. To the
extent such transactions are ongoing business relationships; the transactions are disclosed and, as applicable, reviewed annually.

There
has not been any transaction or series of related transactions to which we were a participant in the 2013 fiscal year or are currently a participant involving an amount in excess of $120,000 and in which any director, executive officer or any member
of their immediate family, or holder of more than five percent of our outstanding common stock, had or will have a direct or indirect material interest.

Director Independence

Our Board has
determined, with the assistance of the Nominating and Corporate Governance Committee of the Board, that each of Messrs. Nemoy, Moll, and Talevich are independent directors as defined by the listing standards of the NASDAQ Marketplace Rules
(NASDAQ Rules) and the rules and regulations of the SEC. In making its independence determinations, the Board considered the following relationship: Mr. Pignatelli was determined to not be independent based on his service beginning
in November 2007 as our interim Chief Executive Officer and based on his service, since January 2008, as our President, and currently as our Chief Executive Officer, and Dr. Arrow was determined to not be independent based on his service,
beginning in June 2013, as our President and Chief Operating Officer.

Determination of Independence

In considering the nature of the services provided by our independent registered public accounting firm, the Audit Committee determined that
such services are compatible with the provision of independent audit services. The Audit Committee discussed these services with our independent registered public accounting firm and our management to determine that they are permitted under the
rules and regulations concerning auditor independence promulgated by the SEC to implement the Sarbanes-Oxley Act of 2002, as well as the American Institute of Certified Public Accountants.

Pre-Approval Policy

According to policies adopted by the Audit Committee and ratified by our Board, to ensure compliance with the SECs rules regarding
auditor independence, all audit and non-audit services to be provided by our independent registered public accounting firm must be pre-approved by the Audit Committee. This policy generally provides that we will not engage any independent registered
public accounting firm to render audit or non-audit services unless the service is specifically approved in advance by the Audit Committee.

From time to time, the Audit Committee may pre-approve specified types of services that are expected to be provided to us by our independent
registered public accounting firm during the next 12 months. Any such pre-approval will be detailed as to the particular service or type of services to be provided and is also generally subject to a maximum dollar amount. In providing any
pre-approval, the Audit Committee considers whether the services to be approved are consistent with the SECs rules on auditor independence.

All fees paid to BDO USA, LLP were pursuant to engagements pre-approved by the Audit Committee, and none of those engagements made use of the
exception to pre-approval contained in Regulation S-X, Rule 2-01(c)(7)(i)(C).
