Executive, as a passive investment, of less than one half of one percent of the outstanding shares of capital stock of any corporation with one or more classes of its capital stock listed on a national securities exchange or publicly traded on the Nasdaq Stock Market or in the over-the-counter market shall not constitute a breach of this Section 6(b).

(e) Solicitation of Employees. Executive hereby agrees that during the Employment Period and for two (2) years thereafter, Executive shall not, either on Executive’s own account or jointly with or as a manager, agent, officer, employee, consultant, partner, joint venturer, owner or stockholder or otherwise on behalf of any other person, firm or corporation, directly or indirectly solicit or attempt to solicit away from the Company any of its officers or employees or offer employment to any person who, on or during the six (6) months immediately preceding the date of such solicitation or offer, is or was an officer or employee of the Company; provided, however, that a general advertisement to which an employee of the Company responds shall in no event be deemed to result in a breach of this Section 6(e).

Page 4

(b) Executive’s employment with the Company shall be “at will,” and either Executive or the Company may terminate Executive’s employment at any time, for any reason, with or without Cause (as defined in Section 7(c)). Any contrary representations, which may have been made to Executive shall be superseded by this Agreement. This Agreement shall constitute the full and complete agreement between Executive and the Company on the “at will” nature of Executive’s employment, which may only be changed in an express written agreement signed by Executive and a dully authorized officer or director of the Company, as approved in a written resolution of the Board.

(c) For the purposes of this Agreement, the term with “Cause” shall mean: (i) Executive’s conviction by, or entry of a plea of guilty in, a court of competent jurisdiction for any crime (other than intoxication) involving any felony punishable by imprisonment in the jurisdiction involved; (ii) gross and willful negligence or misconduct by Executive in the execution of his assigned duties, (provided that such assigned duties do not require Executive to take any actions that are unlawful or otherwise improper); (iii) the willful and material breach of this Agreement by Executive if Executive fails to cure such breach within 30 business days following written notice from the Company; or (iv) Executive’s commission of any act of fraud in connection with his employment by the Company.

(d) In the event the Company terminates the employment of Executive without Cause (as specifically defined in Section 7(c)), the Company shall pay to Executive as severance pay (i) pay an amount equal to six times the base monthly salary Executive was receiving immediately prior to the date of termination (the “Severance Payments”); provided, however, that Executive shall be required to execute a release of claims substantially in the form of Exhibit A and shall not be eligible to receive any such severance payment until said release shall become effective (Immediately upon execution of the Release, and provided that Executive does not exercise any right he may have to revoke the Release, Executive shall receive a initial payment of $5,000, the remaining portion of the Severance Payments will be paid in biweekly intervals for the remaining six month period subject to all applicable withholding requirements as set forth in Section 2 (a)); (ii) COBRA premiums, upon request, paid by Executive with respect to the six-month period following the effective date of such termination; (iii) the pro-rated portion of any performance bonus to which Executive would otherwise have been entitled for the performance period during which such termination becomes effective, such payment to be made within fifteen business days of the date on which it can first be determined that such bonus has been earned; and (iv) vested stock option shares, the amount of which will be determined by the number necessary to ensure Executive receives a minimum of 100,000 stock option shares; provided, however, that Executive, at the time of termination, is not already fully vested in a minimum of 100,000 stock option shares. All of Executive’s vested shares, regardless of the grant to which they apply, will become immediately exercisable at the time of termination. Additionally, subject to any other provision of any agreement evidencing any stock option held by Executive, including the Initial Stock Option, all stock options held by Executive shall be exercisable for a period of six months following the Effective Date of such termination or resignation, provided, however, that such extension is permissible and in accordance with the terms, conditions and overall administration of such plans or programs. Neither Executive’s voluntary

Page 5

resignation of his employment nor the termination of Executive’s employment with Cause shall give rise to Executive’s entitlement to any Severance Payments.

(e) Executive may resign with Good Reason on 30 days’ advance written notice to the Company of such resignation, provided that such notice is given by Executive within 90 days following the occurrence of any event constituting Good Reason (as defined below) and, provided further that the Company does not remedy the basis for such termination prior to the expiration of such 30 days notice period. As used in this Agreement, “Good Reason” shall mean (i) the assignment to Executive, without his consent, of duties inconsistent with Executive’s position so as to constitute a diminution of status with the Company, including an assignment of Executive to a position other than Chief Financial Officer of the ultimate parent company in the event the Company is acquired by, or otherwise becomes a subsidiary of, another company, (ii) a reduction by the Company in the base salary as in effect at any time without Executive’s consent, and (iii) a requirement that Executive relocate (or report on a regular basis) to an office outside of Orange County, California without Executive’s consent.

In addition to the foregoing, if any such termination or resignation is effective after the completion of a performance period for which Executive has earned a performance bonus but before such bonus has been paid, the Company shall pay such performance bonus to Executive as and when such bonus would have been paid absent such termination.

(g) Upon a Change in Control of the Company, as defined as a change in the majority of Board composition within a period of 60 consecutive days or the acquisition by a third party of greater than 50% of the outstanding shares of the Company, all stock options shall immediately become 100% vested and exercisable in full.

Page 6

(h) Executive may voluntarily resign (i.e., without Good Reason) at any time on 30 days’ advance written notice to the Company of such resignation. In the event of any such resignation, the Company may by written notice to Executive, make such resignation effective immediately or as of any date prior to the expiration of the 30 days’ notice period, in which event such resignation shall be effective as of such earlier date; provided, however, that any stock options held by Executive, including the Initial Stock Option, shall continue to vest during the full 30 day notice period even if the Company elects to make such resignation effective immediately or as of any date prior to the expiration of such notice period. Except as otherwise agreed in writing (or as required by law), upon any such resignation, the Company shall have no further obligation to Executive under this Agreement by way of compensation or otherwise other than to pay Executive his base salary through the effective date of such resignation; provided, however, that if such resignation is effective after the completion of a performance period for which Executive has earned a performance bonus but before such bonus has been paid, the Company shall pay such performance bonus to Executive as and when such bonus would have been paid absent such termination. Notwithstanding any contrary provision in any agreement evidencing any stock option held by Executive, including the Initial Stock Option, all stock options held by Executive shall be exercisable for a period of six months following the effective date of such resignation.

(i) In the event of Executive’s death as covered by the Company’s life and accidental death plans, (i) the Company shall pay to Executive’s estate within thirty days of Executive’s death a lump-sum amount equal to the then effective six months of base salary, subject to the immediate offset from the insurance benefit paid subsequent to the qualifying death and (ii) Executive shall vest in additional stock option shares, the amount of which will be determined by the number necessary to ensure Executive’s Estate receives a minimum of 100,000 stock option shares; provided, however, that Executive, at the time of death, is not already fully vested in a minimum of 100,000 stock option shares and all of Executive’s vested shares, regardless of the grant to which they apply, will become immediately exercisable at the time of death (iii) subject to any other provision of any agreement evidencing any stock option held by Executive, including the Initial Stock Option, all stock options held by Executive shall be exercisable for a period of six months following the Effective Date of such death of Executive, provided, however, that such extension is permissible and in accordance with the terms, conditions and overall administration of such plans or programs. Except as required by law, no other compensation will be paid to Executive’s estate; provided, however, that if Executive dies after the completion of a performance period for which Executive has earned a performance bonus but before such bonus has been paid, the Company shall pay such performance bonus to Executive’s estate at such time as it would otherwise have been paid to Executive.

(j) The Company may terminate Executive’s employment on 30 days’ advance written notice to Executive in the event that he at any time becomes unable to perform his duties and responsibilities hereunder due to mental or physical disability, as covered by the Company’s long term disability plan. In the event of any such termination, (i) the Company shall continue to pay to Executive his base salary for a six month period following the effective date of such termination, subject to the immediate offset from the

Page 7

insurance benefit paid subsequent to the covered disability and (ii) Executive shall vest in additional stock option shares, the amount of which will be determined by the number necessary to ensure Executive receives a minimum of 100,000 stock option shares; provided, however, that Executive, at the time of termination, is not already fully vested in a minimum of 100,000 stock option shares and all of Executive’s vested shares, regardless of the grant to which they apply, will become immediately exercisable at the time of termination (iii) subject to any other provision of any agreement evidencing any stock option held by Executive, including the Initial Stock Option, all stock options held by Executive shall be exercisable for a period of six months following the Effective Date of such disability determination, provided, however, that such extension is permissible and in accordance with the terms, conditions and overall administration of such plans or programs. Except as required by law, no other compensation will be paid to Executive upon such termination; provided, however, that if such termination is effective after the completion of a full calendar year in which Executive has earned an annual performance bonus but before such bonus has been paid, the Company shall pay such bonus to Executive as and when such bonus would have been paid absent such termination.

(k) In the event that any payment or benefit received or to be received by Executive upon the termination of his employment, whether payable pursuant to the terms of this Agreement or any other plan, arrangement or agreement by the Company, any predecessor or successor to the Company or any corporation affiliated (within the meaning of Section 1504 of the Internal Revenue Code of 1986, as amended (the “Code”)), with the Company or which becomes affiliated with the Company (collectively all such payments are hereinafter referred to as the “Total Payments”) is deemed to be an “Excess Parachute Payment” (in whole or in part) to Executive within the meaning of Section 280G(b)(1) of the Code as in effect at such time, then, in addition to all other amounts to be paid to Executive by the Company hereunder, the Company shall, within 30 days of the date on which any “Excess Parachute Payment” is made, pay to Executive, in addition to any other payment, coverage or benefit due and owing hereunder, an amount determined by (i) multiplying the rate of excise tax then imposed by Code Section 4999 by the amount of the “Excess Parachute Payment” received by Executive (determined without regard to any payments made to Executive pursuant to this Section 4.7) and (ii) dividing the product so obtained by the amount obtained by subtracting (A) the aggregate local, state and Federal income tax rates applicable to the receipt by Executive of the “Excess Parachute Payment” (taking into account the deductibility for Federal income tax purposes of the payment of state and local income taxes thereon) from (B) the amount obtained by subtracting from 1.00 the rate of excise tax then imposed by Section 4999 of the Code. This total would then be divided by two. It is the Company’s intention that Executive’s net after-tax position be substantially the same as it would have been had Sections 280G and 4999 not been part of the Code for 50% of all outstanding options. For purposes of implementing this Section 4.7, (i) no portion, if any, of the Total Payments, the receipt or enjoyment of which Executive shall have effectively waived in writing prior to the date of payment of the Total Payments, shall be taken into account, and (ii) the value of any non-cash benefit or any deferred cash payment included in the Total Payments shall be determined by the Company’s independent auditors in accordance with the principles of Sections 280G(d)(3) and (4) of the Code.

8. Confidentiality.

(a) As a condition of employment Executive agrees to execute and abide by the Company’s standard Proprietary Information and Inventions Agreement, attached hereto as Exhibit B. In addition, Executive hereby agrees that Executive shall not, directly or indirectly, disclose or make available to any person, firm, corporation, association or other entity for any reason or purpose whatsoever, any Confidential Information (as hereinafter defined). Executive’s obligations under this Section 8 shall continue in effect after the termination of Executive’s employment with the Company, whatever the reason or reasons for such termination, and Executive acknowledges and agrees that the Company shall have the right to communicate with any future or prospective employer of Executive concerning Executive’s continuing obligations under this Section 8. Within ten (10) business days of the effective date of the cessation of Executive’s employment, Executive shall return any Confidential Information to the Company which Executive has in his possession, custody or control. However, that Executive shall not be obligated to treat as confidential, or return to the Company copies of any Confidential Information that (i) was publicly known at the time of disclosure to Executive, (ii) becomes publicly known or available thereafter other than by any means in violation of this Agreement or any other duty owed to the Company by any person or entity, or (iii) is lawfully disclosed to Executive by a third party. As used in this Agreement, the term “Confidential Information” means: information disclosed to Executive or known by Executive as a consequence of or through Executive’s relationship with the Company, about the products, research and development efforts, regulatory efforts, manufacturing processes, customers, employees, business methods, public relations methods, organization, procedures or finances, including, without limitation, information of or relating to customer lists, of the Company and its affiliates.

(b) The Company and Executive intend that the provisions of this Section 8 shall be fully enforceable as set forth herein. To the extent that any court of competent jurisdiction finds that any such provision is unenforceable by reason of its duration or scope, the Company and Executive agree that it shall be enforced insofar as it may be enforced within the limits of the law of that jurisdiction, but that the Agreement as a whole shall be unaffected elsewhere.

(c) The Executive agrees that it would be difficult to compensate Company fully for damages for any violation of the provisions of this Agreement, including, without limitation, the provisions of this Section 8. Accordingly, the Executive specifically agrees that the Company and its successors and assigns shall be entitled to temporary and permanent injunctive relief to enforce the provisions of this Agreement. This provision with respect to injunctive relief shall not, however, diminish the right of the Company to claim and recover damages in addition to injunctive relief.

(d) If Executive breaches any provision of Section 8, the rights of Executive to any benefits under the Agreement (including, but not limited to, any Severance Payments), shall be forfeited, unless the Board determines that such activity is not detrimental to the best interests of the Company and its affiliates. Such forfeiture shall be in addition to any

Page 9

other remedy of the Company under the Agreement or at law and in equity with respect to such breach. However, if Executive ceases such activity and notifies the Board of this action, Executive’s right to receive a benefit, may be restored within sixty (60) days of said notification, unless the Board in its sole discretion determines that the prior activity has caused serious injury to the Company and its affiliates, which determination shall be final and conclusive.

9. Miscellaneous.

(a) Executive represents and warrants to the Company that he is not now under any obligation of a contractual or other nature to any person, firm or corporation which is inconsistent or in conflict with this Agreement, or which would prevent, limit or impair in any way the performance by him of his obligations hereunder.

(b) The waiver by either party of a breach of any provision of this Agreement must be in writing and shall not operate or be construed as a waiver of any subsequent breach thereof.

(c) This Agreement, including Exhibits A and B, contains the complete, final and exclusive agreement of the Parties relating to the terms and conditions of your employment and the termination of Executive’s employment, and supersedes all prior and contemporaneous oral and written employment agreements or arrangements between the Parties. To the extent this Agreement conflicts with the Proprietary Information and Inventions Agreement attached as Exhibit B hereto, the Proprietary Information and Inventions Agreement controls. The representations and warranties contained herein and the Executive’s obligations under Sections 6(d) and 8 shall survive termination of Employment Period and of the Agreement as provided herein.

(d) Any and all notices referred to herein shall be sufficiently furnished if in writing and personally delivered or sent by registered or certified mail, postage prepaid with return receipt requested, by facsimile transmission (if receipt is confirmed) or by courier to the Company at its principal executive office and to the Executive at his address as reflected in the Company’s employment records or such other address as a party may from time to time designate in writing in the manner set forth in this Section 9(d).

(e) If any portion or provision of this Agreement shall be invalid or unenforceable for any reason, there shall be deemed to be made such changes (and only such changes) in such provision or portion as are necessary to make it valid and enforceable. The invalidity or unenforceability of any provision or portion of this Agreement shall not affect the validity or enforceability of any other provision or portions of this Agreement. If any such unenforceable or invalid provision or provisions shall be rendered enforceable and valid by changes in applicable law, then such provision or provisions shall be deemed to read as they presently do in this Agreement without change.

(f) The rights and obligations of the parties hereto shall inure to and be binding upon the parties hereto and their respective heirs, successors and assigns. Without limiting the generality of the foregoing, this Agreement shall be binding upon any successor to the

Page 10

Company whether by merger, acquisition of stock, purchase of all or substantially all of the Company’s assets, reorganization or otherwise. Executive may not assign his rights and duties hereunder, except with the prior written consent of the Company.

(g) This Agreement is intended to and shall be governed by, and interpreted under and construed in accordance with, the laws of the State of California applicable to contracts executed in and wholly performed with such state and without reference to any choice or conflict of laws principles. The payment of base compensation, bonus or benefits may be allocated to or made by such divisions or subsidiaries of the Company as appropriate.

(h) Any controversy, claim or dispute between the parties directly or indirectly concerning this Agreement, or the breach or subject matter hereof, shall be finally settled by arbitration held in Orange County, California. The arbitration will be held under the auspices of either the American Arbitration Association (“AAA”) or Judicial Arbitration & Mediation Services, Inc. (“J•A•M•S”), with the designation of the sponsoring organization to be made by the party who did not initiate the claim. The arbitration shall be in accordance with the AAA’s then-current employment arbitration procedures (if AAA is designated) or the then-current J•A•M•S employment arbitration rules (if J•A•M•S is designated). The arbitrator shall be either a retired judge, or an attorney licensed to practice law in the state in which the arbitration is convened (the “Arbitrator”). The Arbitrator shall have jurisdiction to hear and rule on pre-hearing disputes and is authorized to hold pre-hearing conferences by telephone or in person, as the Arbitrator deems necessary. The Arbitrator shall have the authority to entertain a motion to dismiss, demurrer, and/or a motion for summary judgment by any party and shall apply the standards governing such motions under the applicable rules of civil procedure. The Arbitrator shall render a written award and opinion which reveals, however briefly, the essential findings and conclusions on which the award is based. The arbitration shall be final and binding upon the parties, except as otherwise provided for by the law applicable to review of arbitration decisions/awards. Either party may bring an action in any court of competent jurisdiction to compel arbitration under this Agreement and/or to enforce an arbitration award. The Company will pay the Arbitrator’s fees and any other fees, costs or expenses unique to arbitration, including the filing fee, the fees and costs of the Arbitrator, and rental of a room to hold the arbitration hearing. However, if Executive is the party initiating the claim, Executive shall be responsible for contributing an amount equal to the filing fee to initiate a claim in the court of general jurisdiction in the state which Executive is (or was last) employed by the Company. Each party shall pay for its, his or her, own costs and attorneys’ fees, if any. However, if any party prevails on a statutory claim which entitles the prevailing party to attorneys’ fees and/or costs, or if there is a written agreement providing for fees and/or costs, the Arbitrator may award reasonable fees and/or costs to the prevailing party in accordance with such fee-shifting statute or agreement.

(i) Executive acknowledges (a) that he has consulted with or has had the opportunity to consult with independent counsel of his own choice concerning this Agreement and has been advised to do so by the Company, and (b) Company shall reimburse Executive for his reasonable attorney fees associated with the independent counsel consultation, not to

Page 11

exceed $3000, and (c) that he has read and understands the Agreement, is fully aware of its legal effect, and has entered into it freely based on his own judgment.

(j) No remedy conferred by any of the specific provisions of this Agreement is intended to be exclusive of any other remedy, except as expressly provided in this Agreement, and each and every remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now or hereafter existing in law or in equity or by statute or otherwise. No failure by any party to exercise, and no delay in exercising, any rights will be construed or deemed to be a waiver thereof, nor shall any single or partial exercise by any party preclude any other or future exercise thereof or the exercise of any other right.

10. Indemnification.

The Company shall, to the maximum extent permitted under the General Corporation Law of the State of Delaware, indemnify Executive against any expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement (with the written consent of the Company which shall not be unreasonably withheld) actually and reasonably incurred by Executive in connection with any action, suit or proceeding, whether civil, criminal, administrative or investigative, threatened or initiated against Executive by reason of the fact that he was serving as an officer, director, employee or agent of the Company or was serving at the request of the Company as an officer, director, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The Company shall provide Executive with directors and officer’s liability insurance coverage in an amount at least as favorable to Executive as what the Company maintains as of the date hereof or such greater coverage as the Company may maintain from time to time.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the day and year first above written.

Hohener hereby furnish BioLase Technology, Inc. (the “Company” ), with the following release and waiver ( “Release and Waiver” ).

In exchange for the consideration provided to me by the Employment Agreement that I am not otherwise entitled to receive, I hereby generally and completely release the Company and its directors, officers, employees, shareholders, partners, agents, attorneys, predecessors, successors, parent and subsidiary entities, insurers, affiliates, and assigns from any and all claims, liabilities and obligations, both known and unknown, that arise out of or are in any way related to events, acts, conduct, or omissions occurring prior to my signing this Release and Waiver. This general release includes, but is not limited to: (1) all claims arising out of or in any way related to my employment with the Company or the termination of that employment; (2) all claims related to my compensation or benefits from the Company, including salary, bonuses, commissions, vacation pay, expense reimbursements, severance pay, fringe benefits, stock, stock options, or any other ownership interests in the Company; (3) all claims for breach of contract, wrongful termination, and breach of the implied covenant of good faith and fair dealing; (4) all tort claims, including claims for fraud, defamation, emotional distress, and discharge in violation of public policy; and (5) all federal, state, and local statutory claims, including claims for discrimination, harassment, retaliation, attorneys’ fees, or other claims arising under Title VII of the 1964 Civil Rights Act, as amended, the Age Discrimination in Employment Act, the California Fair Employment and Housing Act, the Equal Pay Act of 1963, as amended, the provisions of the California Labor Code, the Americans with Disabilities Act, the Fair Labor Standards Act, the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and any other state, federal, or local laws and regulations relating to employment and/or employment discrimination. The only exceptions are claims I may have for unemployment compensation and worker’s compensation.

I also acknowledge that I have read and understand Section 1542 of the California Civil Code which reads as follows: “A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor.” I hereby expressly waive and relinquish all rights and benefits under that section and any law of any jurisdiction of similar effect with respect to any claims I may have against the Company.

I acknowledge that, among other rights, I am waiving and releasing any rights I may have under ADEA, that this Release and Waiver is knowing and voluntary, and that the consideration given for this Release and Waiver is in addition to anything of value to which I was already entitled as an executive of the Company. I further acknowledge that I have been advised, as required by the Older Workers Benefit Protection Act, that: (a) the

release and waiver granted herein does not relate to claims under the ADEA which may arise after this Release and Waiver is executed; (b) I have the right to consult with an attorney prior to executing this Release and Waiver (although I may choose voluntarily not to do so); and (c) I have twenty-one (21) days from the date of termination of my employment with the Company in which to consider this Release and Waiver (although I may choose voluntarily to execute this Release and Waiver earlier); (d) I have seven (7) days following the execution of this Release and Waiver to revoke my consent to this Release and Waiver; and (e) this Release and Waiver shall not be effective until the seven (7) day revocation period has expired.

I acknowledge my continuing obligations under my Proprietary Information and Inventions Agreement, a copy of which is attached to the Employment Agreement as Exhibit B. Nothing contained in this Release and Waiver shall be deemed to modify, amend or supersede the obligations set forth in that agreement. I understand and agree that my right to the Severance Payments I am receiving in exchange for my agreement to the terms of this Release and Waiver is contingent upon my continued compliance with my Proprietary Information & Inventions Agreement.

This Release and Waiver, including Exhibit B to the Employment Agreement, constitutes the complete, final and exclusive embodiment of the entire agreement between the Company and me with regard to the subject matter hereof. I am not relying on any promise or representation by the Company that is not expressly stated herein. This Release and Waiver may only be modified by a writing signed by both me and a duly authorized officer of the Company.

I agree that for a period of ten (10) years after my employment with the Company ceases, I will not, in any communication with any person or entity, including any actual or potential customer, client, investor, vendor, or business partner of the Company, or any third party media outlet, make any derogatory or disparaging or critical negative statements – orally, written or otherwise – against the Company, or against any of the Company’s directors, officers, agents, employees, contractors.
