      competing with Company in any way, or acting as an officer, director,
      employee, consultant, stockholder (in excess of 5% of publicly traded
      companies), volunteer, lender, or agent of any business enterprise of the
      same nature as, or which is in direct competition with, the business in
      which Company is now engaged or in which Company becomes engaged during
      the term of Employee's employment with Company, as may be determined by
      Company in its sole discretion, if Company believes such a conflict exists
      during the term of this Agreement, Company may ask Employee to choose to
      discontinue the other work or resign employment with Company. In addition,
      Employee agrees not to refer any client or potential client of Company to
      competitors of Company, without obtaining Company's prior written consent,
      during the term of Employee's employment.

9.    POST-TERMINATION NON-COMPETITION.

      9.1 Consideration For Promise To Refrain From Competing. Employee agrees
      that Employee's services are special and unique, that Company's disclosure
      of confidential, proprietary information and specialized training and
      knowledge to Employee, and that Employee's level of compensation and
      benefits and post-termination severance, as applicable, are partly in
      consideration of and conditioned upon Employee not competing with Company.
      Employee acknowledges that such consideration for Employee's services
      under this Agreement is adequate consideration for Employee's promises
      contained within this Section 9.

      9.2 Promise To Refrain From Competing. Employee understands Company's need
      for Employee's promise not to compete with Company is based on the
      following: (a) Company has expended, and will continue to expend,
      substantial time, money and effort in developing its confidential and
      proprietary information; (b) Employee will in the course of Employee's
      employment develop, be personally entrusted with and exposed to such
      confidential and proprietary information; (c) both during and after the
      term of

                                       -4-
<PAGE>

      Employee's employment, Company will be engaged in the highly competitive
      laser manufacturing industry; (d) Company provides products and services
      nationally and may provide products and services internationally in the
      future; and (e) Company will suffer great loss and irreparable harm if
      Employee were to enter into competition with Company. Therefore, in
      exchange for the consideration described in subsection 9.1 above, Employee
      agrees that for the period of two (2) years following the date Employee is
      terminated or resigns for good cause (as described in Section 7.3) and
      ceases to render services to Company (the "Covenant Period"), Employee
      will not either directly or indirectly, whether as a owner, director,
      officer, manager, consultant, agent or employee: (i) work for a
      competitor, which is defined to include any individual, firm, entity or
      business enterprise that manufactures, sells or distributes lasers, "IPL"
      and "LED" devices with cosmetic and/or competing medical applications,
      other than Company (or such parent, affiliate or subsidiary), in any
      geographical area where Company is now engaged in business, or becomes
      engaged, during the term of Employee's employment ("Restricted Business");
      or (ii) make or hold any investment in any Restricted Business in the
      United States, whether such investment be by way of loan, purchase of
      stock or otherwise, provided that there shall be excluded from the
      foregoing the ownership of not more than four percent (4%) of the listed
      or traded stock of any publicly held corporation. In the case of a
      voluntary resignation by Employee in which Employee receives no Severance
      Payments, the Covenant Period shall be limited to one (1) year. For
      purposes of this Section 9, the term "Company" shall mean and include
      Company, any successor to the business of Company (by merger,
      consolidation, sale of assets or stock or otherwise) and any other
      corporation or entity of which Employee may serve as a director, officer
      or employee at the request of Company or any successor of Company.

      9.3 Reasonableness of Restrictions. Employee represents and agrees that
      the restrictions on competition, as to time, geographic area, and scope of
      activity, required by this Section 9 are reasonable, do not impose a
      greater restraint than is necessary to protect the goodwill and business
      interests of Company, and are not unduly burdensome to Employee. Employee
      expressly acknowledges that Company competes on a worldwide basis and that
      the geographical scope of these limitations is reasonable and necessary
      for the protection of Company's trade secrets and other confidential and
      proprietary information. Employee further agrees that these restrictions
      allow Employee an adequate number and variety of employment alternatives,
      based on Employee's varied skills and abilities. Employee represents that
      Employee is willing and able to compete in other employment not prohibited
      by this Agreement.

      9.4 Reformation if Necessary. In the event a court of competent
      jurisdiction determines that the geographic area, duration, or scope of
      activity of any restriction under this Section 9 and its subsections is
      unenforceable, the restrictions under this Section and its subsections
      shall not be terminated but shall be reformed and modified to the extent
      required to render them valid and enforceable. Employee further agrees
      that the court may reform this Agreement to extend the two (2) year period
      or one (1) year period of this covenant not to compete, whichever is
      applicable, by an amount of time equal to any period in which Employee is
      in breach of this covenant.

      Agreement and for a period of two (2) years after the termination of this
      Agreement, or one (1) year in the case of a voluntary resignation,
      Employee will not either directly or indirectly, separately or in
      association with others, interfere with, impair, disrupt or damage
      Company's relationship with any of its customers or customer prospects by
      soliciting or encouraging others to solicit any of them for the purpose of
      diverting or taking away business from Company.

      11.2 Nonsolicitation of Company's Employees, Employee agrees that during
      the term of this Agreement and for a period of two (2) years after the

      or in association with others, interfere with, impair, disrupt or damage
      Company's business by soliciting, encouraging or attempting to hire any of
      Company's employees or causing others to solicit or encourage any of
      Company's employees to discontinue their employment with Company.

12.   INJUNCTIVE RELIEF. Employee acknowledges that Employee's breach of any of
      the covenants contained in sections 8-11 (collectively "Covenants") would
      cause irreparable injury to Company and agrees that in the event of any
      such breach, Company shall be entitled to seek temporary, preliminary and
      permanent injunctive relief without the necessity of proving actual
      damages or posting any bond or other security.

13.   AGREEMENT TO ARBITRATE. To the fullest extent permitted by law, Employee
      and Company agree to arbitrate any controversy, claim or dispute between

      or benefits claims, constitutional claims; and any claims for violation of

      common law. Claims for workers' compensation, unemployment insurance
      benefits, breach of the Company's Employee Innovations and Proprietary
      Rights Agreement and Company's right to obtain injunctive relief pursuant
      to Section 12 above are excluded. For the purpose of this Agreement to

      related entities and their employees, supervisors, officers, directors,
      agents, fiduciaries, administrators, affiliates and all successors and

      13.1 Consideration. The mutual promise by Company and Employee to
      arbitrate any and all disputes between them (except for those referenced

      provides the consideration for this Agreement to arbitrate.

      13.2 Initiation of Arbitration. Either party may exercise the right to
      arbitrate by providing the other party with written notice of any and all
      claims forming the basis of such right in sufficient detail to inform the
      other party of the substance of such claims. In no event shall the request
      for arbitration be made after the date when institution of legal or
      equitable proceedings based on such claims would be barred by the
      applicable statute of limitations.

      13.3 Arbitration Procedure. The arbitration will be conducted in Boston,
      Massachusetts by a single neutral arbitrator and in accordance with the

      The arbitrator shall have the power to enter any award that could be
      entered by a judge of the trial court of the State of Massachusetts, and
      only such power, and shall follow the law. In the event the arbitrator
      does not follow the law, the arbitrator will have exceeded the scope of
      his or her authority and the parties may, at their option, file a motion
      to vacate the award in court. Subject to the foregoing, the parties agree
      to abide by and perform any award rendered by the arbitrator. Judgment on

      other provision of this Agreement.

      dispute unless a statutory Section at issue, if any, authorizes the award

      14.4 Severability. In the event any provision of this Agreement is found
      to be unenforceable by an arbitrator or court of competent jurisdiction,

      enforceability of the provision as so limited, it being intended that the
      parties shall receive the benefit contemplated herein to the fullest
      extent permitted by law. If a deemed modification is not satisfactory in
      the judgment of such arbitrator or court, the unenforceable provision

Definition of "Adjusted Net Profit" ANP

ANP will be yearly calculated as follows according to the consolidated audited
financials of the Company. ANP will include all entries related to the operation
under direct control of the CEO, and not include items such as one time write
offs and Sona equity loss or gain. Tax impact will be calculated at a standard
rate in order the incentive not to be affected by the company's fiscal policies

+  (A) Profit before taxation
+- (B) Sona equity loss
+- (C) One time write off or earnings
+- (D) minority interest (China sub)

Adjusted Gross Profit = A +- B +- C +- D

Adjusted Net Profit = Gross Adjusted Profit x (1 - 34%)

For the sake of clarity in case ANP had to be calculated on 2002 financials:

(A)= -$2,193,189

(B) = $158,535 loss not to be considered

(C)  NA

(D) = -$70,114 profit share of minority, to be taken out

AGP = -$2,104,760.

If AGP was positive ANP=$1,389,147 = 66% of AGP

      Employee agrees not to refer any client or potential client of Company to
      competitors of Company, without obtaining Company's prior written consent,
      during the term of Employee's employment.

9.    POST-TERMINATION NON-COMPETITION.

      9.1 Consideration For Promise To Refrain From Competing. Employee agrees
      that Employee's services are special and unique, that Company's disclosure
      of confidential, proprietary information and specialized training and
      knowledge to Employee, and that Employee's level of compensation and
      benefits and post-termination severance, as applicable, are partly in
      consideration of and conditioned upon Employee not competing

                                       4

<PAGE>

      with Company. Employee acknowledges that such consideration for Employee's
      services under this Agreement is adequate consideration for Employee's
      promises contained within this Section 9.

      9.2 Promise To Refrain From Competing. Employee understands Company's need
      for Employee's promise not to compete with Company is based on the
      following: (a) Company has expended, and will continue to expend,
      substantial time, money and effort in developing its confidential and
      proprietary information; (b) Employee will in the course of Employee's
      employment develop, be personally entrusted with and exposed to such
      confidential and proprietary information; (c) both during and after the
      term of Employee's employment, Company will be engaged in the highly
      competitive laser manufacturing industry; (d) Company provides products
      and services nationally and may provide products and services
      internationally in the future; and (e) Company will suffer great loss and
      irreparable harm if Employee were to enter into competition with Company.
      Therefore, in exchange for the consideration described in subsection 9.1
      above, Employee agrees that for the period of one (1) year following the
      date Employee ceases to render services to Company (the "Covenant
      Period"), Employee will not either directly or indirectly, whether as a
      owner, director, officer, manager, consultant, agent or employee: (i) work
      for a competitor, which is defined to include any individual, firm, entity
      or business enterprise that manufactures, sells or distributes lasers
      with cosmetic and/or competing medical applications, other than Company
      (or such parent, affiliate or subsidiary, in any geographical area where
      Company is now engaged in business, or becomes engaged, during the term of
      Employee's employment ("Restricted Business"); or (ii) make or hold any
      investment in any Restricted Business in the United States, whether such
      investment be by way of loan, purchase of stock or otherwise, provided
      that there shall be excluded from the foregoing the ownership of not more
      than one percent (5%) of the listed or traded stock of any publicly held
      corporation. For purposes of this Section 9, the term "Company" shall mean
      and include Company, any successor to the business of Company (by merger,
      consolidation, sale of assets or stock or otherwise) and any other
      corporation or entity of which Employee may serve as a director, officer
      or employee at the request of Company or any successor of Company.

      9.3 Reasonableness of Restrictions. Employee represents and agrees that
      the restrictions on competition, as to time, geographic area, and scope of
      activity, required by this Section 9 are reasonable, do not impose a
      greater restraint than is necessary to protect the goodwill and business
      interests of Company, and are not unduly burdensome to Employee. Employee
      expressly acknowledges that Company competes on a worldwide basis and that
      the geographical scope of these limitations is reasonable and necessary
      for the protection of Company's trade secrets and other confidential and
      proprietary information. Employee further agrees that these restrictions
      allow Employee an adequate number and variety of employment alternatives,
      based on Employee's varied skills and abilities. Employee represents that
      Employee is willing and able to compete in other employment not prohibited
      by this Agreement.

      9.4 Reformation if Necessary. In the event a court of competent
      jurisdiction determines that the geographic area, duration, or scope of
      activity of any restriction under this Section 9 and its subsections is
      unenforceable, the restrictions under this Section and its

                                       5

<PAGE>

      subsections shall not be terminated but shall be reformed and modified to
      the extent required to render them valid and enforceable. Employee further
      agrees that the court may reform this Agreement to extend the one (1)
      year period of this covenant not to compete by an amount of time equal to
      any period in which Employee is in breach of this covenant.

10.   CONFIDENTIALITY AND PROPRIETARY RIGHTS. Employee agrees to read, sign and
      abide by Company's [EMPLOYEE INNOVATIONS AND PROPRIETARY RIGHTS ASSIGNMENT
      AGREEMENT], which is incorporated herein by reference.

11.   NON-SOLICITATION.

      11.1 Nonsolicitation of Customers or Prospects. Employee acknowledges that
      information about Company's customers is confidential and constitutes
      trade secrets. Accordingly, Employee agrees that during the term of this
      Agreement and for a period of two (2) years after the termination of this
      Agreement, Employee will not either directly or indirectly, separately or
      in association with others, interfere with, impair, disrupt or damage
      Company's relationship with any of its customers or customer prospects by
      soliciting or encouraging others to solicit any of them for the purpose
      of diverting or taking away business from Company.

      11.2 Nonsolicitation of Company's Employees. Employee agrees that during
      the term of this Agreement and for a period of two (2) years after the
      termination of this Agreement, Employee will not, either directly or
      indirectly, separately or in association with others, interfere with,
      impair, disrupt or damage Company's business by soliciting, encouraging or
      attempting to hire any of Company's employees or causing others to solicit
      or encourage any of Company's employees to discontinue their employment
      with Company.

12.   INJUNCTIVE RELIEF. Employee acknowledges that Employee's breach of any of
      the covenants contained in sections 8-11 (collectively "Covenants") would
      cause irreparable injury to Company and agrees that in the event of any
      such breach, Company shall be entitled to seek temporary, preliminary and
      permanent injunctive relief without the necessity of proving actual
      damages or posting any bond or other security.

13.   AGREEMENT TO ARBITRATE. To the fullest extent permitted by law, Employee
      and Company agree to arbitrate any controversy, claim or dispute between
      them arising out of or in any way related to this Agreement, the
      employment relationship between Company and Employee and any disputes upon
      termination of employment, including but not limited to breach of contract
      tort, discrimination, harassment, wrongful termination, demotion,
      discipline, failure to accommodate, family and medical leave, compensation
      or benefits claims, constitutional claims; and any claims for violation of
      any local, state or federal law, statute, regulation or ordinance or
      common law. Claims for workers' compensation, unemployment insurance
      benefits, breach of the Company's Employee Innovations and Proprietary
      Rights Agreement and Company's right to obtain injunctive relief pursuant
      to Section 12 above are excluded. For the purpose of this Agreement to

<PAGE>

      their employees, supervisors, officers, directors, agents,, fiduciaries,
      administrators, affiliates and all successors and assigns of any of them,
      and this Agreement shall apply to them to the extent Employee's claims
      arise out of or relate to their actions on behalf of Company.

      13.1 Consideration. The mutual promise by Company and Employee to
      arbitrate any and all disputes between them (except for those referenced
      above) rather than litigate them before the courts or other bodies,
      provides the consideration for this Agreement to arbitrate.

      13.2 Initiation of Arbitration. Either party may exercise the right to
      arbitrate by providing the other party with written notice of any and all
      claims forming the basis of such right in sufficient detail to inform the
      other party of the substance of such claims. In no event shall the request
      for arbitration be made after the date when institution of legal or
      equitable proceedings based on such claims would be barred by the
      applicable statute of limitations.

      13.3 Arbitration Procedure. The arbitration will be conducted in Boston,
      Massachusetts by a single neutral arbitrator and in accordance with the
      then current rules for resolution of employment disputes of the American

      representation by an attorney or other representative of their choosing.
      The arbitrator shall have the power to enter any award that could be
      entered by a judge of the trial court of the State of Massachusetts, and
      only such power, and shall follow the law. In the event the arbitrator
      does not follow the law, the arbitrator will have exceeded the scope of
      his or her authority and the parties may, at their option, file a motion
      to vacate the award in court. Subject to the foregoing, the parties agree
      to abide by and perform any award rendered by the arbitrator. Judgment on
      the award may be entered in any court having jurisdiction thereof.

      13.4 Costs of Arbitration. Each party shall bear one half the cost of the
      arbitration filing and hearing fees, and the cost of the arbitrator.

14.   GENERAL PROVISIONS.

      assign any of Employee's rights or obligations under this Agreement.

      14.2 Waiver. Either party's failure to enforce any provision of this

      other provision of this Agreement.

      14.3 Attorneys Fees. Each side will bear its own attorneys' fees in any

      14.4 Severability. In the event any provision of this Agreement is found
      to be unenforceable by an arbitrator or court of competent jurisdiction,

      parties shall receive the benefit contemplated herein to the fullest
