                                                                   -------------


                          TECHNOLOGY LICENSE AGREEMENT
                          ----------------------------

     This Agreement is between O'Donnell Eye Center, Incorporated, a Missouri
corporation, having a place of business at 709 The Hamptons,  Town & Country,
Missouri 63017-5901 ("OECI") and BIOLASE Technology, Inc., a Delaware
corporation having a place of business at 981 Calle Amanecer, San Clemente, CA
92673  ("BIOLASE"), and shall be effective as of July 2, 1998 ("the Effective
Date").

1. GENERAL

   1.1.  OECI is the owner by assignment of a certain new and useful "Laser
         Apparatus and Method for Subsurface Cutaneous Treatment" which is
         disclosed and claimed in a pending United States patent application
         Serial No. 09/015,993, filed on January 30, 1998, together with the
         know-how ancillary thereto ("the KNOW-HOW"), (collectively "the
         TECHNOLOGY").

   1.2.  BIOLASE desires to acquire from OECI the exclusive worldwide rights to
         make, use, import, offer for sale, and sell throughout the world
         products embodying the TECHNOLOGY ("PRODUCTS") for use solely for laser
         treatment in the field of aesthetic "skin rejuvenation" as it now exist
         and as it may exist in the future, including but not limited to
         wrinkle reduction, reduction of rhytides, increased skin tone,
         promotion of new collagen formation, and reduction of striae applicable
         to aesthetic skin rejuvenation ("the FIELD OF USE").

   1.3.  OECI is willing to grant to BIOLASE the exclusive worldwide rights to
         make, use, import, offer for sale, and sell PRODUCTS throughout the
         world for use solely in the FIELD OF USE, subject to the terms and
         conditions stated in this Agreement.

2. GRANT OF LICENSE

   2.1.  In consideration of the issuance by BIOLASE to OECI of 50,000 shares of
         BIOLASE's common stock, $0.001 par value ("the Shares"), OECI hereby
         grants to BIOLASE, and BIOLASE accepts, the exclusive right in
         perpetuity to make, use, import, offer for sale, and sell PRODUCTS
         throughout the LICENSED TERRITORY for use solely in the FIELD OF USE,
         under the terms and conditions stated in this Agreement. As used
         herein, "LICENSED TERRITORY" means the entire world, encompassing all
         its continents and oceans, regardless of whether patent rights exist
         and are enforceable at the time of execution of this Agreement, or
         shall mature and become enforceable during the term of this Agreement,
         in all of the nations in which BIOLASE intends to exercise the rights
         granted to it under this Agreement.

   2.2.  BIOLASE shall have the right to grant sublicenses to third parties for
         the manufacture, use, import, export, offer for sale or sale of
         PRODUCTS or essential components thereof in the LICENSED TERRITORY for
         use solely in the FIELD OF USE according to BIOLASE's best judgment as
         to how the licensed products may be made, sold and generally
         commercialized most efficiently, provided the sublicensees, if any,
         accept and abide by all obligations under this Agreement.

   2.3.  BIOLASE shall mark all licensed products for sale in the LICENSED
         TERRITORY in accordance with the statutes of the United States and/or
         the countries where PRODUCTS are sold relating to marking and labeling
         of medical devices and to marking patented products. BIOLASE shall also
         mark and label PRODUCTS "For use only in laser treatment for the
         purpose of wrinkle reduction, reduction of rhytides, increased skin
         tone, promotion of new collagen formation, and reduction of striae
         applicable to aesthetic skin rejuvenation."

   2.4.  BIOLASE may assign its rights and obligations under this Agreement as
         part of a transfer of all or substantially all of BIOLASE's entire
         business in the PRODUCTS. In all other cases, BIOLASE shall obtain, in
         advance, the approval of OECI of an assignment of BIOLASE's rights and
         obligations under this Agreement to a third party, which approval shall
         not be unreasonably withheld by OECI. BIOLASE shall also obtain the
         agreement of an approved assignee to abide by all the terms and
         conditions of this Agreement.

   2.5.  Nothing in this Agreement shall be construed as obligating OECI or any
         of its officers, directors or employees to provide consulting services
         in connection with the KNOW-HOW to BIOLASE.

3. GRANTS, REPORTS, AND PAYMENTS

   3.1.  (a) OECI understands that the Shares have been issued to OECI pursuant
             to an exemption under the Securities Act of 1933, as amended ("the
             Securities Act") and, accordingly, that the Shares are "restricted"
             securities as defined in the Securities Act and therefore may not
             be sold or otherwise transferred unless registered under the
             Securities Act or an exemption from such registration is available.
             BIOLASE at its expense will, within forty-five (45) days following
             the Effective Date, prepare and file and will thereafter prosecute
             diligently to effectiveness a registration statement under the
             Securities Act, which registration statement shall provide for the
             resale of the Shares. BIOLASE shall also prepare and file such
             amendments and supplements to such registration statement and the
             prospectus contained therein as may be necessary to maintain the
             effectiveness of such registration statement and to make available
             a prospectus meeting the requirements of the Securities Act on as
             continuous a basis as practicable for two years following the
             Effective Date or until such earlier date as counsel for both the
             holder of the Shares and BIOLASE concur that all such Shares may be
             immediately sold pursuant to Rule 144 issued under the Securities
             Act.

         (b) OECI and its shareholders shall cooperate fully with BIOLASE in the
         preparation of such registration statement and shall respond promptly
         and accurately to all reasonable requests from BIOLASE for information
         for inclusion in or otherwise related to such registration statement.

         (c) In connection with the registration of Shares pursuant to this
         Section 3.1, BIOLASE shall indemnify OECI, its affiliates and its
         shareholders against all losses, claims, damages, expenses and
         liabilities caused by or arising out of any untrue statement or alleged
         untrue statement of a material fact contained in any registration
         statement or prospectus (as amended or supplemented) relating to such
         registration statement, or caused by any omission or alleged omission
         to state a material fact required to be stated therein or necessary to
         make the statements therein not misleading in light of the
         circumstances under which they are made, unless such statement or
         omission was made in reliance upon and in conformity with information
         furnished to BIOLASE by OECI, specifically for use therein. OECI shall
         indemnify BIOLASE and its officers, directors, stockholders and other
         persons controlling, controlled by or under common control with BIOLASE
         with respect to losses, claims, damages, expenses and liabilities
         caused by any untrue statement or alleged untrue statement of a
         material fact contained in any registration statement or prospectus (as
         amended or supplemented) relating to such registration statement, or
         caused by any omission or alleged omission to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading in light of the circumstances under which they
         are made to the extent such statement or omission was made in reliance
         upon and in conformity with information furnished by OECI to BIOLASE
         specifically for use in such registration statement or prospectus.

         (d) If the indemnification provided for in this Section 3.1 is
         unavailable to an indemnified party in

Page 2 of 10

 
     respect to any losses, claims, damages, liabilities or expenses referred to
     herein, then an indemnifying party, in lieu of indemnifying such
     indemnified party, shall contribute to the amount paid or payable by such
     indemnified party as a result of such losses, claims, damages, liabilities
     or expenses in such proportion as is appropriate to reflect their relative
     fault in connection with the statements or omissions that resulted in such
     losses, claims, damages, liabilities or expenses. The relative fault shall
     be determined by reference to, among other things, who supplied the
     information to which the untrue or alleged untrue statement of a material
     facts or the omission or alleged omission to state a material fact relates
     and the parties' relative intent, knowledge, access to information and
     opportunity to correct such statement or omission.

3.2. (a)  OECI has filed in the United States such patent applications for the
     TECHNOLOGY ("the U.S. Applications") as OECI deems necessary to protect the
     TECHNOLOGY in the United States.  OECI shall diligently prosecute the U.S.
     Applications, using  Gregory J. Lavorgna, Esq. of Seidel, Gonda Lavorgna
     and Monaco, P.C., 2 Penn Center Plaza, Suite 1800, Philadelphia, PA 19102
     ("Counsel"). OECI shall cause such Counsel to timely notify BIOLASE in
     writing of all costs and fees, including attorneys fees and costs, required
     in connection with the U.S. Applications.  BIOLASE shall promptly pay
     directly to OECI's Counsel, upon demand, all such costs and fees, including
     reasonable attorneys fees and costs, in connection with the U.S.
     Applications from the Effective Date of this Agreement.

     (b)  Within fifty (50) days from the Effective Date of this Agreement,
     BIOLASE shall provide OECI with a list of countries outside the United
     States in which BIOLASE wishes to seek patent coverage ("the BIOLASE
     Foreign Applications List").  OECI shall promptly prepare and file patent
     applications in each country on the BIOLASE Foreign Applications List ("the
     BIOLASE Foreign Applications").  OECI shall diligently prosecute the
     BIOLASE Foreign Applications, using OECI's Counsel.  OECI shall cause such
     Counsel to timely notify BIOLASE in writing of all costs and fees,
     including attorney's fees and costs, required in connection with the
     BIOLASE Foreign Applications. BIOLASE shall promptly pay directly to
     OECI's Counsel, upon demand, all such costs and fees, including reasonable
     attorneys fees and costs, incurred by OECI in connection with the BIOLASE
     Foreign Applications from the Effective Date of this Agreement.

     (c)  Upon receipt of the BIOLASE Foreign Applications List, OECI shall
     review the same and shall provide to BIOLASE a list of additional
     countries, if any, in which OECI wishes to seek patent coverage ("the OECI
     Foreign Applications List").  BIOLASE shall, within twenty (20) working
     days of receipt of the OECI Foreign Applications List, indicate its
     intention to transfer a country listed on the OECI Foreign Applications
     List to the BIOLASE Foreign Applications List.  For each country
     transferred from the OECI Foreign Applications List to the BIOLASE
     Applications List, OECI shall promptly prepare and file patent applications
     in each such country and shall diligently prosecute such applications,
     using OECI's Counsel, and BIOLASE shall promptly upon demand from OECI
     reimburse OECI for all costs and fees, including attorneys fees and costs,
     incurred by OECI in connection with such applications from the Effective
     Date of this Agreement.  OECI shall bear all costs and fees, including
     reasonable attorneys fees and costs, in connection with the preparation,
     filing, and prosecution of patent applications in all countries listed
     solely on the OECI Foreign Applications List.

     (d)  BIOLASE shall have no rights to make, use, import, offer for sale or
     sell PRODUCTS embodying the TECHNOLOGY in the countries listed solely on
     the OECI Foreign Applications List and in which OECI shall have filed and
     prosecuted patent applications.  However, OECI shall not have the right to
     make, use, import, offer for sale or sell or license a third party to make,
     use, import, offer for sale or sell, PRODUCTS embodying the TECHNOLOGY in
     the FIELD of USE and BIOLASE shall have the option to obtain rights to the
     TECHNOLOGY in a country listed solely on the OECI Foreign Applications List
     upon satisfaction of the following conditions:

Page 3 of 10

 
               BIOLASE shall notify OECI in writing of its intent to exercise
               the option and shall pay to OECI an amount equal to one hundred
               fifty percent (150%) of all costs and fees, including attorneys
               fees and costs, actually incurred by OECI from the Effective Date
               of this Agreement in connection with the preparation, filing, and
               prosecution of patent applications in such country.  In the event
               OECI shall have licensed a third party in such country before
               BIOLASE shall have exercised its option under this subparagraph
               3.2(d), and such third party shall have paid all costs and fees,
               including attorneys fees and costs, incurred by OECI in
               connection with the preparation, filing, and prosecution of
               patent applications in such country, then BIOLASE shall  notify
               OECI in writing of its intent to exercise the option, but shall
               not be required to pay to OECI costs and fees associated with the
               patent applications in such country.

     Nothing in this Agreement shall preclude BIOLASE from exercising any rights
     it may have pursuant to this Agreement in countries listed on neither the
     BIOLASE Foreign Applications List nor the OECI Foreign Applications List,
     or in which no patents are granted on the TECHNOLOGY.

3.3. In the event that no U.S. patent issues which covers the TECHNOLOGY, or in
     the event that a court of competent jurisdiction shall enter a final
     judgment that the TECHNOLOGY infringes the valid patent rights of a third
     party, from which judgment no appeal has been or can be taken, OECI shall
     not have any obligation at any time to return the Shares of BIOLASE stock.

3.4. OECI shall not grant rights in and to the TECHNOLOGY to any third party
     which would infringe upon, restrict or otherwise impair the rights granted
     to BIOLASE hereunder.  However, nothing in this Agreement shall prevent
     OECI from using, licensing, or otherwise exploiting the TECHNOLOGY outside
     the FIELD OF USE.

4. REGULATORY APPROVAL

   4.1. BIOLASE shall bear the sole responsibility and expense for securing
        regulatory approval for the sale and use of PRODUCTS in the LICENSED
        TERRITORY as may be required by law.

5. REPRESENTATIONS AND WARRANTIES OF OECI; INDEMNITIES BY OECI

   5.1. OECI hereby represents and warrants to BIOLASE that OECI is the owner of
        the entire right, title and interest in or otherwise has the right to
        use the TECHNOLOGY free and clear of all liens and security interests.

   5.2. All pending applications pertaining to the TECHNOLOGY ("the
        Applications") have been properly made and filed and all annuity,
        maintenance, renewal and other fees relating to the Applications are
        current.

  5.3.  Neither Terry A. Fuller nor Francis E. O'Donnell, Jr., is aware of (i)
        any reason why the TECHNOLOGY would be deemed to be invalid,
        unenforceable, or not in good standing, or (ii) any equitable defenses
        to enforcement based on any act or omission of OECI.

  5.4.  No actions or other judicial or adversary proceedings concerning the
        TECHNOLOGY have been threatened and, to OECI's Knowledge (which means
        the actual knowledge of Terry A. Fuller and Francis E. O'Donnell, Jr.),
        no such action or proceeding is threatened.

  5.5.  To OECI's Knowledge, (i) OECI has the right to use the TECHNOLOGY in its
        business, and (ii)

Page 4 of 10

 
        such use does not conflict with, infringe upon, or violate any rights of
        any other person.

  5.6.  There are no outstanding disputes or other disagreements with respect to
        the TECHNOLOGY, and to OECI's knowledge no such disputes or
        disagreements are threatened.

  5.7.  All of OECI's representations and warranties herein shall expire 24
        months after the Effective Date.

  5.8   OECI has the corporate power to enter into this Agreement and all
        agreements contemplated hereunder, and to carry out its obligations
        hereunder and thereunder. The execution and delivery of this Agreement
        and the performance of OECI's obligations hereunder have been duly
        authorized by the directors of OECI, and no other corporate proceedings
        on the part of OECI are necessary to authorize such execution, delivery,
        and performance.

  5.9   This Agreement has been duly executed by OECI and constitutes a valid
        and legally binding obligation of OECI, enforceable against OECI in
        accordance with the terms hereof.

  5.10  OECI is an "accredited investor", as defined in Rule 501 of Regulation D
        because each of its shareholders (Francis O'Donnell and Terry A. Fuller)
        is an "accredited investor", and is acquiring the Shares for OECI's own
        account and not for the account or benefit of any other person. The
        Shares are being acquired by OECI for investment and not with a view to
        the distribution or resale thereof, except as permitted by the
        Securities Act of 1933 and other applicable securities laws.

        By reason of the business and financial experience of OECI, its
        affiliates and the persons OECI has retained to advise it with respect
        to the transactions contemplated by this Agreement, none of whom are
        directly indirectly affiliated with or compensated by BIOLASE, OECI has
        such knowledge, sophistication and experience in business and financial
        matters to enable OECI to evaluate the merits and risks of the
        acquisition of Shares.

        OECI has carefully reviewed and considered (i) BIOLASE's Annual Report
        on Form 10'K for the year ended December 31, 1997, (ii) BIOLASE's
        Quarterly Report on Form 10-Q for the quarter ended March 31, 1998,
        (iii) BIOLASE's proxy statement dated April 20, 1998 for its Annual
        Meeting of Stockholders held on May 19, 1998 and (iv) BIOLASE's Private
        Placement Memorandum dated April 21, 1998, receipt of each of which is
        hereby acknowledged, and understands and has evaluated the risks of an
        acquisition of Shares, including without limitation the risks set forth
        in the Memorandum under "Risk Factors". Except as indicated in the next
        sentence, OECI has relied on no information supplied by or on behalf of
        BIOLASE other than the information contained in the above-referenced
        Reports, proxy statement and the Memorandum. OECI confirms that it has
        been given the opportunity to ask questions of BIOLASE and its
        management concerning BIOLASE and the Shares, and OECI has received
        satisfactory written responses to all such questions, if any.

  5.11  From and after the Effective Date, OECI agrees to indemnify and hold
        harmless BIOLASE and its officers, directors, and agents from and
        against any damages, liabilities, assessments, losses, costs, and
        expenses (including but not limited to reasonable attorneys' fees and
        other expenses incurred in litigation or otherwise) (collectively
        "Losses") suffered or paid, directly or indirectly, as a result of any
        and all claims, demands, suits, causes of action, proceedings, or
        judgments, assessed, incurred, or sustained by or against BIOLASE or any
        of its officers, directors, or agents, arising out of, resulting from,
        or related to the transaction between OECI and BIOLASE under this
        Agreement, including but not limited to the following:

        i.   the failure of any representation or warranty made by OECI in this
             Agreement to be

Page 5 of 10

 
            true and correct in all material respects as of the EFFECTIVE DATE
            (but not for Losses in excess of the value of the Shares on the date
            hereof); and

       ii.  the breach by or nonperformance of OECI of its obligations under
            this Agreement.

   5.12  Other than as set forth herein, OECI makes no representations or
         warranties of any kind, express or implied, under this Agreement with
         regard to the TECHNOLOGY or to the merchantability, fitness, or fitness
         for a particular purpose of any products produced pursuant to the
         rights and license granted herein. OECI shall have no responsibility
         under this Agreement for any loss of profits, or punitive,
         consequential, or indirect damages.

6. REPRESENTATIONS AND INDEMNITIES BY BIOLASE; INSURANCE

   6.1.  BIOLASE has the corporate power to enter into this Agreement and all
         agreements contemplated hereunder, and to carry out its obligations
         hereunder and thereunder. The execution and delivery of this Agreement
         and the performance of BIOLASE's obligations hereunder have been duly
         authorized by the directors of BIOLASE, and no other corporate
         proceedings on the part of BIOLASE are necessary to authorize such
         execution, delivery, and performance.

   6.2.  This Agreement has been duly executed by BIOLASE and constitutes a
         valid and legally binding obligation of BIOLASE, enforceable against
         BIOLASE in accordance with the terms hereof.

   6.3.  From and after the Effective Date, BIOLASE agrees to indemnify and hold
         harmless OECI and its officers, directors, and agents from and against
         any damages, liabilities, assessments, losses, costs, and expenses
         (including but not limited to reasonable attorneys' fees and other
         expenses incurred in litigation or otherwise) (collectively "Losses")
         suffered or paid, directly or indirectly, as a result of any and all
         claims, demands, suits, causes of action, proceedings, or judgments,
         assessed, incurred, or sustained by or against OECI or any of its
         officers, directors, or agents, arising out of, resulting from, or
         related to the transaction between OECI and BIOLASE under this
         Agreement, including but not limited to the following:
           i.   the failure of any representation or warranty made by BIOLASE in
                this Agreement to be true and correct in all material respects
                as of the EFFECTIVE DATE;
           ii.  the breach by or nonperformance of BIOLASE of its obligations
                under this Agreement;
           iii. claims of a third party that any product made, used, sold, or
                offered for sale pursuant to this Agreement or any sublicense
                hereunder (except for sublicenses by OECI pursuant to Section
                3.2(d) hereof) infringes the rights or properties of such third
                party, except insofar as such product is limited solely to the
                TECHNOLOGY.

   6.4.  OECI shall provide BIOLASE with written notice of all such claims,
         demands, suits, causes of action, proceedings, assessments, or
         judgments within thirty (30) days after OECI acquires knowledge
         thereof. In the event such notice is not given to BIOLASE, BIOLASE
         shall be relieved of its indemnity obligations under this Agreement if
         BIOLASE is materially prejudiced by such failure to give such notice.

   6.5.  BIOLASE shall maintain at its own expense in full force and effect at
         all times during which PRODUCTS are being sold, with a responsible
         insurance carrier, at least a Three Million Dollar ($3,000,000)
         products liability insurance policy with respect to PRODUCTS. This
         insurance policy shall name OECI as co-insured.

   8.1.  In the event of a material breach of any provision of this Agreement,
         or default on any obligation imposed on either party by this Agreement,
         the non-breaching party shall give written notice of the breach to the
         other party within sixty (60) days of the non-breaching party learning
         of said breach or default. If the breach or default shall not have been
         remedied within thirty (30) days of written notice of the breach, or if
         such breach or default cannot be cured within thirty (30) days, or if
         the other party shall not have commenced a cure within such thirty (30)
         days and thereafter diligently prosecuted such cure to completion, the
         non-breaching party shall have the right to terminate this Agreement
         immediately by written notice.

   8.2.  BIOLASE acknowledges that compliance with the provisions of this
         Agreement is necessary to protect the business and good will of OECI,
         and that any breach of this Agreement will result in irreparable and
         continuing damage to OECI, for which money damages will not provide
         adequate relief. Consequently, BIOLASE agrees that in the event BIOLASE
         breaches or threatens to breach a material provision of this Agreement,
         OECI shall have the following rights and remedies, each of which rights
         and remedies shall be independent of the others and severally
         enforceable, and each of which is in addition to, and not in lieu of,

              specifically enforced against BIOLASE by any court of competent
              jurisdiction, it being agreed that any breach or threatened breach
              of a material provision of this Agreement would cause irreparable
              injury to OECI and that money damages would not provide an
              adequate remedy to OECI.

          ii. Accounting. The right and remedy to require BIOLASE to account for
              ----------
              and pay over to OECI all profits, moneys, accruals, increments, or
              other benefits derived or received by BIOLASE as a result of any
              transactions constituting a material breach of the provisions of
              this Agreement.

   8.3.  OECI acknowledges that compliance with the provisions of this Agreement
         is necessary to protect the business and good will of BIOLASE, and that
         any breach of this Agreement will result in irreparable and continuing
         damage to BIOLASE, for which money damages will not provide adequate
         relief. Consequently, OECI agrees that in the event OECI breaches or
         threatens to breach a material provision of this Agreement, BIOLASE
         shall have the following rights and remedies, each of which rights and
         remedies shall be independent of the others and severally enforceable,
         and each of which is in addition to, and not in lieu of, any other
         rights and remedies available to BIOLASE under law or in equity:

          i.  Specific Performance.  The right and remedy to have this Agreement
              --------------------                                              
              specifically enforced against OECI by any court of competent
              jurisdiction, it being agreed that any breach or threatened breach
              of a material provision of this Agreement would cause

              irreparable injury to BIOLASE and that money damages would not
              provide an adequate remedy to BIOLASE.

  8.4.  BIOLASE and OECI each acknowledges that it has had the assistance of
        legal counsel in the review and execution of this Agreement.

  8.5.  Waiver by either OECI or BIOLASE of any right, or failure to perform or

        otherwise.

9. CONFIDENTIALITY OF INFORMATION

  9.1.  It is recognized by the parties that in carrying out this Agreement,
        knowledge and experience furnished by one party to the other will
        contain and incorporate confidential and proprietary information. Each
        party agrees that it shall maintain as confidential all such
        information, which is not publicly known or is acquired in a manner that
        would not constitute a breach of this Agreement, for the term of this
        Agreement. Upon termination of this Agreement prior to the term hereof,
        the receiving party agrees that it will make no further use of the
        confidential information of the disclosing party; and the receiving
        party agrees upon such termination to immediately deliver to the
        disclosing party such information as it shall possess in tangible or
        written form, including all copies thereof.

10. ENFORCEMENT OF INTELLECTUAL PROPERTY RIGHTS

 10.1.  BIOLASE, as exclusive licensee in the FIELD OF USE, shall have the
        right to seek legal remedies for infringement of the patent rights in
        the FIELD OF USE, if any, covering the TECHNOLOGY by filing and
        prosecuting actions for infringement. Unless to remedy a breach by OECI
        of its representations and warranties in this Agreement, any legal
        action undertaken by BIOLASE to enforce the licensed patent rights shall
        be at BIOLASE's sole cost and expense. Any recovery of damages, costs of
        the action, attorney fees, and all other financial damages recovered in
        an action for infringement of the patent rights shall belong to BIOLASE.
        If BIOLASE determines to settle any such infringement action, BIOLASE
        shall first gain approval from OECI, which shall not be unreasonably
        withheld. OECI hereby agrees to be named as a plaintiff in any
        infringement action that BIOLASE deems it necessary to prosecute,
        provided BIOLASE pays all of OECI's costs and expenses incurred in
        connection therewith and fully indemnifies OECI against all losses
        arising out of, relating to or connected with, any such action. BIOLASE
        shall give notice to OECI before filing any infringement lawsuit.

 10.2.  Nothing in this Agreement, including the provision in the previous
        paragraph granting BIOLASE the right to sue and recover damages for
        infringement of the patent rights, if any, covering the TECHNOLOGY,
        shall be construed to require BIOLASE to sue any infringer or all
        infringers. BIOLASE may exercise its business discretion to determine
        the necessity or practicality of enforcing the patent rights at all
        times during the term of this Agreement. Nothing in this Agreement shall
        be construed to prevent OECI from suing an infringer of any of the
        patents and retaining all damages recovered by OECI. OECI shall give
        notice to BIOLASE before filing an infringement lawsuit on any patent
        covering the TECHNOLOGY.

     14.1.  In the event that the performance by any party hereto of its
            obligations hereunder shall be interrupted or delayed by any

            whether such occurrence be an act of God or the common enemy or the
            result of war, riot, civil commotion or sovereign conduct, then the
            party whose performance is so delayed or interrupted shall be
            excused from such performance for such period of time as is
            reasonably necessary after the occurrence to remedy the effects
            thereof.

           commenced under or to enforce this Agreement, provided that a copy of
           any such process shall be delivered to BIOLASE, its successors, or
           assigns, in accordance with the notice provisions of this Agreement.

     15.2. This Agreement shall be construed and enforced according to the law
