The Seller is the owner of a production center with ten employees in Floss,
Germany (hereinafter referred to as the "Business").

The Seller is interested in divesting itself of the Business by way of a
transfer of the assets and contractual relationships relating thereto. The
Purchaser is interested in purchasing certain assets and contractual

     balance sheet being part of the audited annual statement of the Seller as
     of September 30, 2001, and taking into account subsection 3 below. Assets
     of the Business, which did not have to be included in the inventory in view
     of their particular nature (e.g. low value items), are nevertheless
     included in the assets sold pursuant to this Article 1.

Purchaser assumes from the Seller all rights and obligations resulting from
these contracts by way of the assumption of contract with full discharge of the

     dispute in connection with the termination of the employee.

5.   In the event, the Purchaser has to terminate more than 3 of the employees
     listed in Attachment 4.2, then the parties shall equally share the
               --------------
     Termination Costs (as defined in subsection 3 above) of those additional
     employees.

6.   The indemnification in subsections 4 and 5 above shall be conditioned on
     the Purchaser, prior to the termination of the respective employee listed
     in Attachment 4.2 having consulted and discussed in good faith with the
        --------------
     Seller its intention to terminate the employee.

7.   The entitlement to the indemnification in subsections 4 and 5 above shall
     lapse, if (i) the Purchaser files a petition for bankruptcy or has such
     petition filed involuntarily against it, or files a petition for suspension
     of payments, becomes insolvent, makes an assignment for the benefit of
     creditors, goes into liquidation or receivership, or otherwise loses legal
     control of its business, or (ii) comes under the control of a third party
     (e.g., by virtue of acquisition or merger) two years or more after the
     Effective Date.

                                   ARTICLE 5
                     Transfer of Title, Grant of Possession
                     --------------------------------------

1.   The Seller hereby transfers to the Purchaser, who hereby accepts such
     transfer, title to the assets sold pursuant to Article 1 of this Agreement
     with effect as of the Effective Date. The transfer from the Seller to the
     Purchaser of the real estate referred to in Article 2 of this Agreement is

                              Third Party Consents
                              --------------------

1.   The parties will jointly endeavor to obtain all necessary third party
     consents in respect of the transferred assets and assigned contractual
     relationships, and the entry into certain contracts and contractual offers;
     in particular, the parties will endeavor to obtain the consent of
     contractual partners.

2.   If it turns out to be impossible or impracticable to obtain the consent of
     a third party which is necessary in connection with the effective transfer
     of an asset or the assignment of a contractual relationship, or the
     effective entry into a contractual relationship or contractual offer, the
     parties will, for the purposes of their internal relationship (im
     Innenverhaltnis), behave and conduct themselves as if the transfer or entry
     had effectively taken place on the Effective Date. In this case, the Seller
     will, in respect of its external relationships (im Aussenverhaltnis),
     remain the owner of the relevant asset and remain the party to the relevant
     contractual relationship but will continue to hold the relevant asset and
     the relevant contract or contractual offer in the internal relationship

     between the Seller and the Purchaser for the account of the Purchaser.
     Thus, the Purchaser shall indemnify the Seller for any losses, damages,
     liabilities to third parties, costs or expenses (including taxation) it
     might incur in connection therewith.

                                   ARTICLE 7

the Seller related to the Business, including but not limited to (i) any
liabilities in connection with the transferred assets or the assigned
contractual relationships incurred until the Effective Date and (ii) any
liabilities of the Seller relating to accounts payable, indebtedness, legal
services, accounting services, financial advisory services or other professional
services performed in connection with the Business.

                                   ARTICLE 8
                                 Purchase Price

     relationships, and the assignment of the contractual relationships

2.   A first installment of the Purchase Price which shall amount according to
     the sole discretion of the Purchaser between US-$ 300,000.00 (in words:
     United States Dollar three-hundred-thousand) and US-$ 500,000.00 (in words:
     United States Dollar five-hundred-thousand) shall be paid by the Purchaser
     not later than May 31, 2002 but not before the 12th day after the Notary

5.   The portion of the Purchase Price outstanding from time to time shall, from
     the Effective Date until payment, bear interest at an annual rate
     calculated in accordance with the following formula:

                                     *****.

     The interest is due and payable on the last business day of each month.

6.   On the date the first installment of the Purchase Price is due, the
     Purchaser shall provide the Seller with a direct suretyship of BIOLASE
     Technology, Inc., payable upon first demand (selbstschuldnerische
     Burgschaft auf erstes Anfordern) in the amount of the remaining balance of
     the Purchase Price. This suretyship must be returned by the Seller upon
     receipt of the final installment of the Purchase Price at the latest. If,
     at the time of the intended return of the suretyship, the parties do not
     agree as to whether there are any warranty claims in respect of which the
     Purchaser can exercise a right of set off against the outstanding claim for
     the Purchase Price or a portion thereof, the Seller may nevertheless demand
     from the Purchaser payment of the full amount of the final installment of
     the Purchase Price if the Seller, in order to secure the warranty amount in
     dispute, provides at the same time a direct suretyship payable upon first
     demand (selbstschuldnerische Burgschaft auf erstes Anfordern) of a bank or
     savings bank which is recognized as a customs or tax surety.

7.   The Purchase Price agreed upon in subsection 1 above is a net amount. The
     Purchaser shall be solely responsible for and shall pay, or reimburse the
     Seller for any German Value Added Tax due under this Agreement. The Seller
     shall provide the Purchaser with according invoices separately stating the
     Purchase Price and Value Added Tax.

8.   If payment of the first installment of the Purchase Price is not made when
     due as specified in subsection 2 above, then the Seller has the right to
     withdraw from this Agreement (zurucktreten), if the Purchaser has not cured
     this failure within 14 banking days after having received the Seller's
     written notice that payment of the first installment of the Purchase Price
     is still outstanding. The right of the Seller to demand damages from the
     Purchaser on the basis of non-completion is not affected by the exercise of
     this right of withdrawal.

9.   The Purchase Price and any interest resulting therefrom shall be payable in
     the European currency Euro ("EUR" or "(euro)"). The exchange rate to be
     applied for the conversion from United States Dollars (US-$) to EUR.
     (hereinafter referred to as the "Exchange Rate") shall be the average
     exchange rate as stated in the London Financial Times on the date of the
     notarial recording of this Agreement. The Exchange Rate shall be applicable
     to any and all payments under this Agreement.

                            Warranties of the Seller
                            ------------------------

The Seller warrants to the Purchaser, in the form of an independent promise of
guarantee (unabhangiges Garantieversprechen), that the following statements, as
at the Effective Date, are true and correct:

1.   The Seller has the right to freely dispose of the assets sold pursuant to
     Article 1 and 2 of this Agreement without any third parties' consent being
     required and without such a disposal infringing the rights of third
     parties. The Seller is the legal and beneficial owner of all assets sold
     pursuant to Article 1 subsection 1 and Article 2 of this Agreement. Such
     assets are free of all encumbrances or any other rights in favor of third
     parties and are in good operating and maintenance condition.

2.   The validity or enforceability of the contracts transferred pursuant to
     Article 3 of this Agreement has not been legally contested or challenged.
     No such contract has been terminated nor, to the best knowledge of the
     Seller, is any such termination pending. Neither the Seller nor, to the
     best knowledge of the Seller, its respective contractual partner, has
     breached, or is in default with respect to, any such contract.

3.   Attachment 4.2 to this Agreement is a complete and correct list of all
     --------------
     employees of the Seller transferred pursuant to Article 4 of this Agreement
     specifying the name of each such employee and the aggregate amount in
     Deutsche Mark of the compensation (including wages, salary, commissions,
     director's fees, fringe benefits, bonuses, profit- sharing payments and
     other payments or benefits of any type) received by such employee from the
     Seller with respect to the services performed in 2001.

     No employee indicated in that list as ***** has declared an intention to
     terminate the employment relationship.

     Except as set forth in Attachment 4.2 to this Agreement, the Seller is not
                            --------------
     a party to or bound by, any employment contract or any union contract,
     collective bargaining agreement or similar contract in connection with the
     transferred employees.

     To the best of Seller's knowledge, no transferred employee is a party to or
     bound by any confidentiality agreement, non-competition agreement or other
     contract with any person that may have an adverse effect on the performance
     by such employee of any of his duties or responsibilities as an employee of
     the Seller or the Purchaser.

4.   The business facilities of the Business have been erected in compliance
     with all applicable laws and regulatory orders (in particular in the area
     of construction and trade law). Neither their operation nor any other
     current business operations of the Business nor any of its products or
     services infringe any applicable laws or regulatory orders. All relevant
     permits required in connection with the operation of the Business have been
     granted (Realkonzessionen). To the best knowledge of the Seller, neither
     the revocation nor any restrictions in respect of such permits is or are
     impending. All necessary insurances are valid and in full force up until
     the Effective Date.

5.   Bankruptcy or composition proceedings have not been commenced against the
     Seller nor are there any circumstances visible which would justify the
     commencement of such proceedings in the foreseeable future. There is also
     no pending proceeding against or involving the Seller that is related to
     the Business or any transferred asset or employment relationship or
     assigned contract, and to the knowledge of the Seller, no person has
     threatened to commence any proceeding against or involving the Seller that
     is related to the Business or the transferred assets or employment
     relationships or assigned contracts. To the knowledge of the Seller, there
     is no proposed order that, if issued or otherwise put into effect, (i)
     would be reasonably likely to have a material adverse effect on the ability
     of the Seller to comply with or perform any covenant or obligation under
     any provision of this Agreement or (ii) would reasonably be expected to
     have the effect of preventing, delaying, making illegal or otherwise
     interfering with any of the transactions contemplated hereby.

6.   To the best knowledge of the Seller, all information supplied by the Seller
     to the Purchaser and its advisers prior to the notarial recording of this
     Agreement is complete, correct and accurate in all respects. It is not
     misleading and does not omit any fact relating to the Business and the
     assets and contractual and employment relationships transferred pursuant to
     this Agreement which would be important in respect of specific information
     given or which the Purchaser at the time of the notarial recording of this
     Agreement should have known for the purposes of evaluating such
     information. To the best knowledge of the Seller, there are no material
     facts or circumstances, which in the future could have a material adverse
     effect on the Business and its operations as well as on the transferred
     assets and employment relationships and assigned contracts with the
     exception of general developments of the economy or the market.

7.   The Seller has all requisite legal power and authority to enter into this
     Agreement and to consummate the transactions contemplated thereby. The
     execution and delivery of this Agreement and the consummation of the
     transactions contemplated hereby have been duly authorized by all necessary
     legal bodies of the Seller. This Agreement has been duly executed and
     delivered by the Seller and constitutes the valid and binding obligation of
     the Seller enforceable against the Seller in accordance with its terms.

8.   The execution and delivery of this Agreement by the Seller does not, and
     the consummation of the transactions contemplated hereby will not, conflict
     with, or result in any violation of, or default under (with or without
     notice or lapse of time, or both), or give rise to a right of termination,
     cancellation or acceleration of any obligation or loss of any benefit under
     any other agreement of the Seller and Purchaser.

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

1.   If one or several of the statements in respect of which the Seller has,
     pursuant to Article 9 of this Agreement, assumed a guarantee turns out to
     be inaccurate, then the Purchaser may demand that the Seller, within an
     appropriate period of time but in any case not later than 30 days after
     receipt of such demand brings about the position which would have existed
     had such statements been correct. If the Seller, within such period of
     time, fails to produce such position or if it is impossible to do so, the
     Purchaser may demand damages from the Seller.

2.   The Purchaser may claim damages on the basis of non-fulfillment of the
     guarantees assumed by the Seller pursuant to Article 9 of this Agreement
     only to the extent that the aggregate amount of such claims exceeds an
     amount of EUR ***** (in words: Euro *****). This limitation has no
     application in respect of legal defects (Rechtsmangel) of the assets sold.

3.   Expressly excluded are any rights of the Purchaser relating to exchange
     (Wandlung) or reduction of purchase price (Minderung), damages for
     incorrect representation (Schadenersatz wegen unrichtiger Zusicherung),
     avoidance of this Agreement due to lack of substantial quality (Anfechtung
     wegen des Fehlens einer wesentlichen Eigenschaft) or rescission or
     adjustment of this Agreement due to lack of substantial elements (Wegfall
     der Geschaftsgrundlage) or damages for other negligent breach of contract
     (Schadensersatz wegen Pflichtverletzung).

4.   All warranty claims of the Purchaser pursuant to this Article 10 are
     subject to a limitation period of two (2) years. This has no application in
     respect of legal defects of the assets sold, which are subject to the
     statutory limitation period. The limitation period commences on the
     Effective Date.

                       Confidentiality and Press Releases
                       ----------------------------------

1.   The Seller shall keep confidential for a period of 2 years from the
     Effective Date its knowledge concerning the Business and its business
     operations if the relevant facts are not publicly known and to the extent
     that no legal disclosure requirements exist and shall, furthermore, not use
     such confidential information for itself or for others.

2.   The parties agree to keep strictly confidential any information obtained by
     them in connection with the negotiation and conclusion of this Agreement
     which relates to the relevant other party and its affiliated companies.

3.   Neither party shall make any press release nor any similar public
     announcement with respect to the transactions contemplated in this
     Agreement without the prior written agreement of the relevant other party.
