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 . Should Optionee’s Service cease for any 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.

      6.  Change in Control .

          (a) If Optionee’s is terminated without Cause or Optionee resigns for Good Reason (as defined in Optionee’s Employment Agreement) within twelve months following the effective date of a Change in Control (as defined in Optionee’s Employment Agreement), 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.

            (b) 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.

          (c) 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.

This Award is not granted pursuant to the BIOLASE, Inc. 2002 Stock Incentive Plan (the “ Plan ”), however, except to the extent otherwise set forth herein, the terms and conditions of the Plan applicable to restricted stock units are incorporated herein by reference and shall apply as though the Award was granted pursuant to the Plan.

2.  Rights as a Stockholder . The Holder shall not be entitled to any privileges of ownership with respect to the shares of Common Stock subject to the Award unless and until, and only to the extent, such shares become vested pursuant to Section 3 hereof and the Holder becomes a stockholder of record with respect to such shares. As of each date on which the Company pays a cash dividend to record owners of shares of Common Stock (a “ Dividend Date ”), then the number of shares subject to the Award shall increase by (i) the product of the total number of shares subject to the Award immediately prior to such Dividend Date multiplied by the dollar amount of the cash dividend paid per share of Common Stock by the Company on such Dividend Date, divided by (ii) the Fair Market Value of a share of Common Stock on such Dividend Date.

3.3. Termination of Employment . Subject to Section 3.2 above, if the Holder’s employment with the Company terminates prior to the end of the Restriction Period, then the portion of the Award that was not vested immediately prior to such termination of employment shall be immediately forfeited by the Holder and cancelled by the Company.

5.2. Investment Representation . The Holder hereby represents and covenants that (a) any share of Common Stock acquired upon the vesting of the Award will be acquired for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the “ Securities Act ”), unless such acquisition has been registered under the Securities Act and any applicable state securities laws; (b) any subsequent sale of any such shares shall be made either pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws; and (c) if requested by the Company, the Holder shall submit a written statement, in form satisfactory to the Company, to the effect that such representation (x) is true and correct as of the date of vesting of any shares of Common Stock hereunder or (y) is true and correct as of the date of any sale of any such share, as applicable. As a further condition precedent to the delivery to the Holder of any shares of Common Stock subject to the Award, the Holder shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance or delivery of the shares and, in connection therewith, shall execute any documents which the Board shall in its sole discretion deem necessary or advisable.

6.  Additional Terms and Conditions of Award .

6.1. Withholding Taxes . (a) The Company shall have the right to require, prior to the issuance or delivery of any shares of Common Stock upon the vesting of the Award, payment by the Holder of such Award of any federal, state, local or other taxes which may be required to be withheld or paid in connection with such Award (the “ Required Tax Payments ”).

(b) The Holder may satisfy his or her obligation to advance the Required Tax Payments by any of the following means: (1) a cash payment to the Company, (2) delivery (either actual delivery or by attestation procedures established by the Company) to the Company of previously owned whole shares of Common Stock having an aggregate Fair Market Value, determined as of the date the obligation to withhold or pay taxes arises in connection with the Award (the “ Tax Date ”), equal to the Required Tax Payments, (3) authorizing the Company to withhold whole shares of Common Stock which would otherwise be delivered or an amount of cash which would otherwise be payable to the Holder having an aggregate Fair Market Value, determined as of the Tax Date, equal to the Required Tax Payments or (4) any combination of (1), (2) and (3). Shares of Common Stock to be delivered or withheld may not have an aggregate Fair Market Value in excess of the amount determined by applying the minimum statutory withholding rate. Any fraction of a share of Common Stock which would be required to satisfy such an obligation shall be disregarded and the remaining amount due shall be paid in cash by the Holder.

6.2. Compliance with Applicable Law . The Award is subject to the condition that if the listing, registration or qualification of the shares of Common Stock subject to the Award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the delivery of shares hereunder, the shares of Common Stock subject to the Award shall not be delivered, in whole or in part, unless such listing, registration, qualification, consent, approval or other action shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent, approval or other action.

6.3. Section 409A . This Agreement is intended to comply with the requirements of Section 409A of the Code, and shall be interpreted and construed consistently with such intent. The payments to the Holder pursuant to this Agreement are also intended to be exempt from Section 409A of the Code to the maximum extent possible as short-term deferrals pursuant to Treasury regulation §1.409A-1(b)(4). In the event the terms of this Agreement would subject the Holder to taxes or penalties under Section 409A of the Code (“ 409A Penalties ”), the Company and the Holder shall cooperate diligently to amend the terms of this Agreement to avoid such 409A Penalties, to the extent possible; provided that in no event shall the Company be responsible for any 409A Penalties that arise in connection with any amounts payable under this Agreement. To the extent any amounts under this Agreement are payable by reference to the Holder’s termination of employment, such term shall be deemed to refer to the Holder’s “separation from service,” within the meaning of Section 409A of the Code. Notwithstanding any other provision in this Agreement, if the Holder is a “specified employee,” as defined in Section 409A of the Code, as of the date of Holder’s separation from service, then to the extent any amount payable to the Holder (i) constitutes the payment of nonqualified deferred compensation, within the meaning of Section 409A of the Code, (ii) is payable upon the Holder’s separation from service and (iii) under the terms of this Agreement would be payable prior to the six-month anniversary of the Holder’s separation from service, such payment shall be delayed until the earlier to occur of (a) the first business day following the six-month anniversary of the separation from service and (b) the date of the Holder’s death.

6.4. Award Confers No Rights to Continued Employment . In no event shall the granting of the Award or its acceptance by the Holder, or any provision of the Agreement, give or be deemed to give the Holder any right to continued employment by the Company, any Subsidiary or any affiliate of the Company or affect in any manner the right of the Company, any Subsidiary or any affiliate of the Company to terminate the employment of any person at any time.

6.5. Decisions of Plan Administrator . The Plan Administrator shall have the right to resolve all questions which may arise in connection with the Award. Any interpretation, determination or other action made or taken by the Plan Administrator regarding the Plan or this Agreement shall be final, binding and conclusive.

6.6. Successors . This Agreement shall be binding upon and inure to the benefit of any successor or successors of the Company and any person or persons who shall, upon the death of the Holder, acquire any rights hereunder in accordance with this Agreement or the Plan.
