 Inducement Option Grant 

BIOLASE, INC. 
 STOCK
OPTION AGREEMENT 
 A. The Board has granted the Option to Optionee as an inducement material to Optionee’s employment with
the Corporation. 
 B. Optionee is to render valuable services to the Corporation (or a Parent or Subsidiary), and this Agreement is
executed pursuant to the Corporation’s grant of the Option to Optionee. 
 C. All capitalized terms in this Agreement shall have
the meaning assigned to them in the attached Appendix A. 
 Now, therefore, it is hereby agreed as follows: 

1. Grant of Option. The Corporation hereby grants to Optionee, as of the Grant Date, an option to purchase no more than the
number of Option Shares specified in the Grant Notice. The Option Shares shall be purchasable from time to time during the option term specified in Paragraph 2 at the Exercise Price. 

2. Option Term. The Option shall expire on the Expiration Date, unless sooner terminated in accordance with this Agreement.

 3. Limited Transferability. Except as otherwise provided in this Paragraph 3, the Option shall be neither
transferable nor assignable by Optionee other than by will or the laws of inheritance following Optionee’s death and may be exercised, during Optionee’s lifetime, only by Optionee. The Option may be assigned in whole or in part during
Optionee’s lifetime to one or more of Optionee’s family members (as such term is defined in the instructions to Form S-8), or to Optionee’s former spouse through a gift or domestic relations order. The terms applicable to the assigned
portion shall be the same as those in effect for the Option immediately prior to such assignment. 
 4. Dates of Exercise.
The Option shall become exercisable for the Option Shares as specified in the Grant Notice. If the Option is exercisable in installments, then as the Option becomes exercisable for such installments, those installments shall accumulate, and the
Option shall remain exercisable for the accumulated installments until the Expiration Date or sooner termination of the Option pursuant to this Agreement. 

5. Cessation of Service. 

(a) Should Optionee’s Service cease for any reason (other than death, Disability, Misconduct or termination for Good Reason) while
the Option is outstanding, then the Option shall be exercisable for the number of Option Shares for which the Option was vested and exercisable at the time Optionee’s Service ceased and shall remain outstanding and exercisable until the
earlier of (i) the Close of Business on the last day of the three month period commencing on the date Optionee’s Service ceased or (ii) the Expiration Date; provided, however, that if Optionee terminates Service
voluntarily and does not give the Corporation at least 30 days’ notice, then the Option shall terminate immediately upon cessation of Service with respect to all Option Shares. 

(b) Should Optionee’s Service cease due to death, Disability or for Good Reason while the Option is outstanding, then the Option
shall be exercisable for the full number of Option Shares and shall remain outstanding and exercisable until the earlier of (i) the Close of Business on the anniversary of the date Optionee’s Service ceased or (ii) the
Expiration Date. 
 (c) Should Optionee’s Service be terminated for Misconduct or should Optionee otherwise engage in any
Misconduct while the Option is outstanding, then the Option shall terminate immediately with respect to all Option Shares. 
 (d) Upon
the expiration of such limited post-Service exercise period or (if earlier) upon the Expiration Date, the Option shall terminate with respect to all Option Shares for which the Option is exercisable. 

6. Change in Control. 

(a) Immediately prior to the effective date of a Change in Control, the Option shall vest and become exercisable for all of the Option
Shares and may be exercised for any or all of those Option Shares. However, the Option shall not vest and become exercisable on an accelerated basis under this subsection (a) if and to the extent: (i) the Option is to be assumed by the
successor corporation (or parent thereof) or is otherwise to be continued in full force and effect pursuant to the terms of the Change in Control transaction or (ii) the Option is to be replaced with a cash incentive 







 program of the successor corporation which preserves the spread existing at the time of the Change in Control on
the Option Shares for which the Option is not otherwise at that time exercisable (the excess of the Fair Market Value of those Option Shares over the aggregate Exercise Price payable for such shares) and provides for subsequent payout of that spread
no later than the time the Option would have vested and become exercisable for those shares. 
 (b) Immediately following the
consummation of the Change in Control, the Option shall terminate, except to the extent assumed by the successor corporation (or parent thereof) or otherwise continued in effect pursuant to the terms of the Change in Control
transaction.  
 (c) If the Option is assumed or otherwise continued in effect in connection with a Change in Control, then
the Option shall be appropriately adjusted by the Board, upon such Change in Control, to apply to the number and class of securities which would have been issuable to Optionee in consummation of such Change in Control had the Option been exercised
immediately prior to such Change in Control, and appropriate adjustments shall also be made to the Exercise Price, provided the aggregate Exercise Price shall remain the same. To the extent that the holders of Common Stock receive cash
consideration for their Common Stock in consummation of the Change in Control, the successor corporation (or its parent) may, in connection with the assumption of the Option, substitute one or more shares of its own common stock with a fair market
value equivalent to the cash consideration paid per share of Common Stock in such Change in Control. The adjustments determined by the Board shall be binding on all parties who have an interest in the Option. 

(d) This Agreement shall not in any way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its
capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. 

7. Other Transactions. Should any change be made to the Common Stock by reason of any stock split, reverse stock split,
stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation’s receipt of consideration, appropriate adjustments shall be made by the Board
to (a) the number and/or class of securities subject to the Option and (b) the Exercise Price in order to reflect such change and thereby preclude a dilution or enlargement of benefits hereunder. The adjustments determined by the Board
shall be binding on all parties who have an interest in the Option. 
 8. Stockholder Rights. The holder of the Option
shall not have any stockholder rights with respect to the Option Shares until such person shall have exercised the Option, paid the Exercise Price and become the holder of record of the purchased Option Shares. 

9. Manner of Exercising Option. 

(a) In order to exercise the Option with respect to all or any part of the Option Shares for which the Option is at the time exercisable,
Optionee (or any other person or persons permitted to exercise the Option) must take the following actions: 
 (i) Execute
and deliver to the Corporation a Notice of Exercise for the Option Shares for which the Option is exercised; 
 (ii) Pay the
aggregate Exercise Price for the purchased shares in one or more of the following forms: 
 (A) cash or check made payable to
the Corporation; 
 (B) shares of Common Stock (1) held by Optionee (or any other person or persons permitted to
exercise the Option) for the requisite period necessary to avoid a charge to the Corporation’s earnings for financial reporting purposes and (2) valued at Fair Market Value on the Exercise Date; or 

(C) to the extent the Option is exercised for vested shares, through a special sale and remittance procedure pursuant to which
Optionee (or any other person or persons permitted to exercise the Option) shall concurrently provide irrevocable instructions (1) to a brokerage firm to effect the immediate sale of the purchased shares and remit to the Corporation, out of the
sale proceeds available on the settlement date, sufficient funds to cover the aggregate Exercise Price payable for the purchased shares plus all applicable income and employment taxes required to be withheld by the Corporation by reason of such
exercise and (2) to the Corporation to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale. 







 Except to the extent the sale and remittance procedure is utilized in connection with the option
exercise, payment of the Exercise Price must accompany the Notice of Exercise. 
 (iii) Furnish to the Corporation
appropriate documentation that the person or persons exercising the Option (if other than Optionee) have the right to exercise the Option. 

(iv) Make appropriate arrangements with the Corporation (or Parent or Subsidiary employing or retaining Optionee) for the
satisfaction of all income and employment tax withholding requirements applicable to the Option exercise. 
 (b) As soon
as practical after the Exercise Date, the Corporation shall issue to or on behalf of Optionee (or any other person or persons exercising the Option) a certificate for the purchased Option Shares, with the appropriate legends affixed thereto. 

(c) In no event may the Option be exercised for any fractional shares. 

10. No Right to Continued Service. Nothing in the Grant Notice or this Agreement shall confer upon Optionee any right to
continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Corporation (or any Parent or Subsidiary employing or retaining Optionee) or of Optionee, which rights are hereby expressly
reserved by each, to terminate Optionee’s Service at any time for any reason, with or without cause. 
 11. Compliance with
Laws and Regulations. 
 (a) The exercise of the Option and the issuance of the Option Shares upon such exercise shall be
subject to compliance by the Corporation and Optionee with all applicable requirements of law relating thereto and with all applicable regulations of any applicable stock exchange or quotation system on which the Common Stock may be traded at the
time of such exercise and issuance. The Option cannot be exercised if doing so would violate the Corporation’s internal policies, including, but not limited to, its insider trading policy. 

(b) The inability of the Corporation to obtain approval from any regulatory body having authority deemed by the Corporation to be
necessary to the lawful issuance and sale of any Common Stock pursuant to the Option shall relieve the Corporation of any liability with respect to the non-issuance or sale of the Common Stock as to which such approval shall not have been obtained.

 12. Successors and Assigns. Except to the extent otherwise provided in this Agreement, the provisions of this Agreement
shall inure to the benefit of, and be binding upon, the Corporation and its successors and assigns and Optionee, Optionee’s permitted assigns, the legal representatives, heirs and legatees of Optionee’s estate, whether or not any such
person shall have become a party to this Agreement or has agreed in writing to join herein and be bound by the terms hereof. 

13. Notices. Any notice required to be given or delivered to the Corporation under the terms of this Agreement shall be
addressed to the Corporation at its principal corporate offices. Any notice required to be given or delivered to Optionee shall be addressed to Optionee at the address indicated below Optionee’s signature line on the Grant Notice or at such
other address as Optionee may designate by ten days advance written notice to the Corporation. Any notice required to be given under this Agreement shall be in writing and shall be deemed effective upon personal delivery or upon the third day
following deposit in the U.S. mail, registered or certified, postage prepaid and properly addressed to the party entitled to such notice. 

14. Entire Agreement. The Grant Notice and this Agreement (and any exhibit and appendix hereto) constitute the entire
agreement between the parties hereto with regard to the subject matter hereof. All decisions of the Board with respect to any question or issue arising under the Grant Notice and this Agreement shall be and binding on all persons having an interest
in the Option. 
 15. Amendments. The Grant Notice and this Agreement may only be amended in an instrument executed by
both parties. Approval of the Board is required for all material amendments to the Grant Notice or this Agreement. 

16. Governing Law. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of the
State of Delaware without giving effect to that State’s choice-of-law or conflict-of-law rules. 
 17. Additional Terms and
Conditions. The Option, and the Grant Notice and this Agreement, shall be subject to the additional terms and conditions set forth in the attached Appendix B.

 (b) The Board shall, within the scope of its administrative functions under the Option, have full power and authority (subject to the
provisions of the Grant Notice and this Agreement) to establish such rules and procedures as it may deem appropriate for proper administration of the Option and to make such determinations under, and issue such interpretations of, the provisions of
the Option as it may deem necessary or advisable. Decisions of the Board within the scope of its administrative functions under the Grant Notice and this Agreement shall be binding on all parties who have an interest in the Option. 

2. Tax Withholding 

(a) The Corporation’s obligation to deliver shares of Common Stock upon the exercise of the Option shall be subject to the
satisfaction of all applicable income and employment tax withholding requirements. 
 (b) The Board may, in its discretion, provide any
holder of the Option with the right to use shares of Common Stock in satisfaction of all or part of the Withholding Taxes to which such holder may become subject in connection with the exercise of the Option. Such right may be provided to any such
holder in either or both of the following formats: 
 (i) Stock Withholding. The election to have the Corporation
withhold, from the shares of Common Stock otherwise issuable upon the exercise of the Option, a portion of those shares. So as to avoid adverse accounting treatment, the number of shares that may be withheld for this purpose may not exceed the
minimum number needed to satisfy the applicable income and employment tax withholding rules. 
 (ii) Stock Delivery.
The election to deliver to the Corporation, at the time the Option is exercised, one or more shares of Common Stock previously acquired by such holder (other than in connection with the Option exercise triggering the Withholding Taxes). So as to
avoid adverse accounting treatment, the number of shares that may be withheld for this purpose may not exceed the minimum number needed to satisfy the applicable income and employment tax withholding rules. 

3. Restriction on Repricing of the Option. Except with the approval of the stockholders of the Corporation, the Option may
not be amended to reduce the exercise price per share of the Common Stock of the Corporation subject to the Option below the exercise price of the Option as of the date the Option is granted, except to reflect the substitution for or assumption of
the Option in connection with a Change in Control of the Corporation or if any change is made in the Common Stock subject to the Option without the receipt of consideration by the Corporation (through merger, consolidation, reorganization,
recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of
consideration by the Corporation) in which case the Option will be appropriately adjusted in the class or classes and number of securities and price per share of Common Stock subject to the Option. In the event of the substitution for or assumption
of the Option in connection with a Change in Control of the Corporation or if any change is made in the Common Stock subject to the Option without the receipt of consideration by the Corporation, the Board shall make such adjustments, and its
determination shall be final, binding and conclusive. (The conversion of any convertible securities of the Corporation shall not be treated as a transaction “without receipt of consideration” by the Corporation.). 

4. Amendment of the Option. The Board shall have complete and exclusive power and authority to amend the Grant Notice and
this Agreement. However, no such amendment of the Grant Notice and this Agreement shall adversely affect the rights and obligations with respect to the Option unless the Optionee consents to such amendment. 

5. Use of Proceeds. Any cash proceeds received by the Corporation from the sale of shares of Common Stock under the Option
shall be used for any corporate purpose. 







 6. Regulatory Approvals. 

(a) The granting of the Option and the issuance of any shares of Common Stock upon the exercise of the Option shall be subject to the
Corporation’s procurement of all approvals and permits required by regulatory authorities having jurisdiction over the Option, and the shares of Common Stock issued pursuant to the Option. 

(b) No shares of Common Stock or other assets shall be issued or delivered under the Option unless and until there shall have been compliance
with all applicable requirements of applicable securities laws, including the filing and effectiveness of the Form S-8 registration statement for the shares of Common Stock issuable under the Option, and all applicable requirements of any stock
exchange or the Nasdaq Stock Market on which Common Stock is then listed for trading or traded.
