Item 2.        Acquisition or Disposition of Assets.
- -------        -------------------------------------

          On July 2, 1998, BioLase Technology, Inc., a Delaware corporation (the
"Company"), acquired substantially all of the assets and assumed certain
specified liabilities of Laser Skin Toner, Inc., a Missouri corporation ("LSTI")
(the "Acquisition").  The assets acquired relate primarily to LSTI's proprietary
laser-based technology providing non-invasive laser treatment in the field of
aesthetic skin rejuvenation, including all intellectual property rights
(consisting of patents, patent applications, a trademark application and certain
know-how) (the "Assets").

          As consideration for the Assets, the Company issued to LSTI an
aggregate of 1,600,000 authorized but previously unissued shares of the
Company's Common Stock, $.001 par value (the "Shares"), 1,417,120 of which were
delivered to LSTI at the closing of the Acquisition.  The remaining 182,880
Shares (the "Performance Shares") were issued in the name of LSTI, but will be
retained by the Company pending the achievement by the business based on the
Assets of specified performance objectives.  The number of Shares to be issued
in the transaction was determined by the Company based upon negotiations between
LSTI and the Company regarding the respective value of the Assets and the
Shares.  The Company has agreed to register under the Securities Act of 1933, as
amended, under certain conditions, no less than one-half of the Shares then held
by LSTI or its shareholders.

          The Assets were being developed by LSTI, an early stage development
company, for applications including use in the field of aesthetic skin
rejuvenation. The Company intends, once commercial development has been
achieved, to manufacture and market the laser Skin Toner system based on the
Assets in such field through its newly formed Aesthetics Division, which also
includes the Company's patented DermaLase(TM) HydroKinetic(TM) System and Lazer
ToothBrush(TM).

          The Company and Terry A. Fuller, Ph.D., President and CEO and a
principal shareholder of LSTI, have agreed to negotiate in good faith with a
view towards a definitive agreement establishing an ongoing relationship that
would include granting the Company a right of first refusal to technology
developed by Dr. Fuller with potential applications in aesthetics and cutaneous
surgery.

          Pursuant to a separate agreement, the Company also issued 50,000
shares of its Common Stock to O'Donnell Eye Centers Incorporated, a Missouri
corporation (OECI), in consideration for the license of technology that is the
subject of a pending patent application. Frank O'Donnell, M.D., the Chairman of
LSTI, is an officer, director and principal shareholder of OECI.

Board of Directors
Laser Skin Toner, Inc.
St. Louis, Missouri

We have audited the accompanying balance sheets of Laser Skin Toner, Inc., a
development stage company, as of March 31, 1998 and December 31, 1997, 1996, and
1995, and the related statements of operations, changes in stockholders'
deficit, and cash flows for the three months and the years then ended,
respectively.  These financial statements are the responsibility of the
company's management.  Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material aspects, the financial position of Laser Skin Toner, Inc., a
development stage company, at March 31, 1998 and December 31, 1997, 1996, and
1995 and the results of its operations and its cash flows for the three months
and the years then ended, respectively, in conformity with generally accepted
accounting principles.

              MARCH 31, 1998 AND DECEMBER 31, 1997, 1996 AND 1995


NOTE 1 - OPERATIONS AND SUMMARY OF SIGNIFICANT
         ACCOUNTING POLICIES

         OPERATIONS
         The company is a development stage company engaged in the development
         of a proprietary non-invasive, laser technology for functionally and
         aesthetically improving the skin.  A company related through common
         ownership has provided substantially all of the funding expended by the
         company for the research and development of the technology.  The
         development period began in 1997.  The company had been inactive in the
         immediately preceding years.

         The company is currently negotiating the sale of the laser technology
         it has developed.  Under the terms of the proposed sale, the company
         will receive up to 1,600,000 shares of unregistered common stock of
         BioLase Technologies, Inc., a publicly traded company based in
         California. Management expects continued funding from the related
         company if the sale is not consummated.

         RESEARCH AND DEVELOPMENT COSTS
         Research and development costs are charged to expense as incurred.

         ORGANIZATION COSTS
         Organization costs are amortized over a period of five years under the
         straight-line method.

         ESTIMATES

         The preparation of financial statements in conformity with generally
         accepted accounting principles requires management to make estimates
         and assumptions that affect the reported amounts of assets and
         liabilities, disclosure of contingent assets and liabilities at the
         date of the financial statements, and reported amounts of revenues and
         expenses during the reporting period.  Actual results could differ from
         those estimates.

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


NOTE 2 - RELATED PARTY TRANSACTIONS

         The amounts due to and from affiliated companies and due from
         stockholder are unsecured, non-interest bearing loans due on demand.

         The notes payable to related parties are unsecured.  Principal and
         interest at 9% per annum are due on December 31, 1998.

NOTE 3 - INCOME TAXES

         At December 31, 1997, the company has net operating loss carryforwards
         of $296,760 which are available to offset future taxable income.  The
         loss carryforwards expire at various dates between 2007 and 2012.
 
         Deferred income taxes are provided for temporary differences between
         the tax and financial reporting bases of the company's assets and
         liabilities and for the future tax benefit related to its net operating
         loss carryforward. Deferred income taxes are based on enacted tax laws
         and statutory tax rates expected to be in effect in the periods in
         which the differences or net operating loss are expected to affect
         taxable income. The differences, which relate to research and
         development costs and professional fees, as well as the net operating
         loss would result in deferred tax assets. The deferred tax assets
         represent the estimated future tax return consequences of the
         aforementioned items, which will be deductible when the assets are
         recovered or the net operating loss is utilized. Deferred tax assets
         are reduced by a valuation allowance when management believes it is
         more likely than not that the deferred tax assets will not be realized.
         A valuation allowance has been applied to reduce deferred tax assets to
         zero as follows:

its obligations under the Contracts which remain to be performed after the date
hereof;

               (c) There has not occurred any material default under any of the

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

Date balance sheet included in Schedule 3.4, LSTI has no liabilities or
obligations of any nature, whether absolute, accrued, contingent or otherwise,

               -----------------                                               
this Agreement and the Schedules attached hereto does not and will not contain
any untrue statement of a material fact or omit to state a material fact
required to be stated herein or therein or necessary to make the statements and

hereafter delivered or made available to BioLase pursuant hereto were or will be
complete and accurate copies of such documents.

no Affiliate now has or since January 1, 1997 has had, either directly or
indirectly:

               (a) An equity or debt interest in any corporation, partnership,
joint venture, association, organization or other person or entity which

in any way competitive with the business of LSTI.

    3.18  Acquisition of Shares.  LSTI is an "accredited investor", as defined
          ---------------------                                       
in Rule 501 of Regulation D, because all of the Shareholders are accredited
investors. LSTI is acquiring the Shares for LSTI's own account and not for the
account or benefit of any other Person other than the Shareholders. The Shares
are being acquired by LSTI 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 LSTI, its
Affiliates and the persons LSTI has retained to advise it with respect to the
transactions contemplated by this Agreement, none of whom are directly or
indirectly affiliated with or compensated by BioLase, LSTI has such knowledge,
sophistication and experience in business and financial matters to enable LSTI
to evaluate the merits and risks of the acquisition of Shares.

          LSTI has carefully reviewed and considered the BioLase SEC Reports and
the PPM Memorandum, receipt 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 on Schedule 3.18 or in the next sentence, LSTI has relied on no
information supplied by or on behalf of the Company other than the information
contained in the BioLase SEC Reports and the PPM.  LSTI confirms that it has
been given the opportunity to ask questions of BioLase and its management
concerning BioLase and the Shares, and LSTI has received satisfactory written
responses to all such questions, if any.

                                 ARTICLE IV
                                 ----------

                        Certain Covenants and Agreements
                        --------------------------------

    4.1   Registration.  BioLase hereby agrees that in the event it is 
          ------------                                                
determined by the Internal Revenue Service that the transactions contemplated by
this Agreement do not qualify as a tax-free reorganization under Section 368(a)
of the IRC, it will within sixty (60) days after the written request of
Shareholders holding a majority of the Shares ("Majority Shareholders")
following such a determination prepare and file and thereafter prosecute
diligently to effectiveness a registration statement under the Securities Act of
1933, as amended (the "Securities Act") in order to provide LSTI with a current
prospectus meeting the requirements of the Securities Act and covering the
resale of no less than one-half (1/2) of the Shares held by the Shareholders at
the time such registration statement is filed.

                                      -16-
<PAGE>
 
In addition, in the event it is determined that any of the Shareholders may not
avail themselves of the provisions of Rule 144 promulgated under the Securities
Act generally available to holders of restricted securities in order to resell
Shares (for reasons other than their status as "affiliates" under Rule 144),
BioLase hereby agrees it will within sixty (60) days after the written request
of the Majority Shareholders (which request may not be made during the ten
months immediately following the Closing Date) following such a determination
prepare and file and thereafter prosecute diligently to effectiveness a
registration statement under the Securities Act of 1933, as amended (the
"Securities Act") in order to provide the Shareholders with a current prospectus
meeting the requirements of the Securities Act and covering the resale of all
Shares held by such Shareholders at the time such registration statement is
filed.

          No registration statement need be filed pursuant to this Section 4.7
and Shares need not be included within the coverage of any such registration
statement that is filed to the extent each Shareholder is then able pursuant to
the provisions of Rule 144 under the Securities Act to immediately offer and
sell Shares which BioLase would otherwise be required to register pursuant to
the provisions of this Section 4.1.

          LSTI and the Shareholders shall cooperate fully with BioLase in the
preparation of any 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.

          In connection with the registration of Shares pursuant to this Section
4.1, BioLase shall indemnify LSTI, its Affiliates and the 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 LSTI or any
Shareholder, respectively, specifically for use therein.  LSTI and each of the
Shareholders 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

                                      -17-
<PAGE>
 
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 such Shareholder to BioLase specifically for use in
such registration statement or prospectus.

          If the indemnification provided for in this Section 4.1 is unavailable
to an indemnified party in 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 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.

          All expenses of any registration referred to in this Section 4.1,
except fees and disbursements of counsel for and other advisors to LSTI or the
Shareholders, underwriting or brokerage commissions or discounts in connection
with sales by LSTI or the Shareholders and any transfer or other taxes
applicable to the transfer of Shares by LSTI or the Shareholders, shall be borne
by BioLase.

    4.2   Exploitation of Assets.  Subject to its commercial judgment which it
          ----------------------                                           
shall exercise in good faith, BioLase shall use its best efforts to exploit the
Assets, develop the Unit, the related products described on Schedule 1.3 and the
Business, and market the Unit and the related products in a manner that does not
subvert the opportunity of LSTI or the Shareholders to obtain the release and
delivery of Performance Shares pursuant to Section 1.3 hereof, including (but
not limited to) the diligent prosecution of any applications for necessary
clearances from the FDA to market the Unit as a medical device.

    4.3   SEC Reports.  So long as any of the Shares are subject to the
          -----------                                                  
limitations imposed by Rule 144 promulgated under the Securities Act other than
the provisions of Rule 144(k), BioLase will timely file all reports it is
required to file pursuant to the provisions of the Securities Exchange Act of
1934, as amended.

    4.4   Restrictions on Shares.  LSTI acknowledges and agrees that the Shares
          ----------------------                                        
shall be issued without registration under the Securities Act of 1933, as
amended (the "Securities Act") and shall be "restricted securities" as defined
in Rule 144

                                      -18-
<PAGE>
 
promulgated under the Securities Act.  LSTI will only offer or resell the Shares
in compliance with the provisions of all applicable securities laws and
regulations.  LSTI will offer or resell the Shares only if the Shares are
registered under the Securities Act or an exemption from such registration is
available (in which latter case BioLase shall have received an opinion of
counsel, in form and substance reasonably satisfactory to BioLase and its
counsel, to such effect).  Unless such registration has been effected or such an
exemption is available, BioLase shall not permit the transfer of the Shares.

          LSTI understands and agrees that BioLase may take such reasonable
steps as it deems appropriate to ensure compliance with the offer, resale and
other restrictions on transfer contained in this Agreement or arising under
applicable securities laws, including instituting "stop transfer" instructions
with respect to the Shares and endorsing restrictive legends, such as the
following, on certificates representing the Shares:

          "The securities represented by this Certificate have not been
          registered under the Securities Act of 1933, as amended (the
          "Securities Act") and are "restricted securities" as that term is
          defined in Rule 144 under the Securities Act.  The securities may not
          be offered for sale, sold or otherwise transferred except pursuant to
          an effective registration statement under the Securities Act or
          pursuant to an exemption from registration under the Securities Act,
          the availability of which is to be established to the satisfaction of
          the Issuer."

          LSTI further agrees that LSTI will not transfer the Shares to any
Person under circumstances in which such Shares remain restricted securities, as
defined in Rule 144 issued under the Securities Act, in the hands of such
transferee without first obtaining for the benefit of BioLase and transmitting
to BioLase the written representation and undertaking (in form reasonably
satisfactory to BioLase) of such transferee (i) representing that the matters
set forth in Section 3.18 are, with such exceptions as may be reasonably
acceptable to BioLase, are true and correct with respect to the transferee and
(ii) undertaking to observe the obligations of LSTI pursuant to this Section
4.4.

          BioLase and LSTI understand that LSTI intends to liquidate prior to
December 31, 1998, and that LSTI currently intends to distribute to the
Shareholders any Shares that it has received on or prior to such date.  At the
time of such distribution, LSTI will obtain from each Shareholder, as a
condition to such distribution, a written certification that such

                                      -19-
<PAGE>
 
Shareholder is an "accredited investor" as defined in Rule 501 of Regulation D,
as well as the written representations and undertakings described in the
previous paragraphs of this Section 4.4.

     4.5  Right of First Refusal; Advisory Board.  Within and no later than ten
          --------------------------------------

negotiate in good faith a definitive agreement with respect to an ongoing
relationship including, but not limited to, BioLase's right of first refusal as
to technology developed by Fuller with potential applications in aesthetics and
cutaneous surgery.  As soon as possible after the execution of this Agreement,
BioLase shall create an Advisory Board, and may appoint Fuller as the Chairman
thereof.

     6.1  By LSTI and the Principal Shareholders.  LSTI and the Principal
          --------------------------------------                         
Shareholders shall indemnify and hold harmless BioLase in respect of any and all
claims, losses, damages, liabilities and expenses (including, without
limitation, settlement costs and any legal or other expenses for investigating,
defending or preparing to defend any actions, investigations or other
proceedings or threatened actions, investigations or other proceedings),
reasonably incurred by BioLase in connection with, arising out of or as a result
of any (a) breach of any representation or warranty made by LSTI in this
Agreement, or (b) breach by LSTI of any of its covenants and other obligations
contained in this Agreement.

     6.2  By BioLase.  BioLase shall indemnify and hold harmless LSTI and the
          ----------                                                         
Shareholders in respect of any and all claims, losses, damages, liabilities and

expenses for investigating, defending or preparing to defend any actions,
investigations or other proceedings or threatened actions, investigations or
other proceedings), reasonably incurred by LSTI and the Shareholders in

"Indemnitee") shall promptly notify the party against whom or which the claim is
being asserted (the "Indemnitor") of the claim and, to the extent known, the
facts constituting the basis for such claim.  In the event of any claim for
indemnification hereunder resulting from or in connection with any claim or
legal proceedings by a third party, such notice shall specify, if known, the
amount or an estimate of the amount of the liability arising therefrom.
Indemnitee shall not settle or compromise any claim by a third party for which
Indemnitee is entitled to indemnification hereunder without the prior written
consent (not to be unreasonably withheld) of Indemnitor, unless suit in respect

not have taken control of such suit after notification thereof or Indemnitor
shall not be entitled to take control thereof pursuant to Section 9.4 of this

     6.4  Defense by Indemnitor.
          --------------------- 

          (a)  In connection with any claim which may give rise to indemnity
hereunder resulting from or arising out of any claim or legal proceeding by a
person other than an Indemnitee (a "Third Party Claim"), the Indemnitor, at the
sole cost and expense of Indemnitor, may, upon written notice to Indemnitee,
assume the defense of any such Third Party Claim if Indemnitor (i) provides
evidence reasonably satisfactory to Indemnitee of Indemnitor's economic ability
to provide such indemnification and (ii) unconditionally acknowledges to
Indemnitee his or its obligation to indemnify Indemnitee pursuant hereto in
respect of such Third Party Claim.  If Indemnitor assumes the defense of any
such Third Party Claim, Indemnitor shall select counsel reasonably acceptable to
Indemnitee to conduct the defense of such Third Party Claim and, at the sole
cost and expense of Indemnitor, shall take all steps necessary in the defense or
settlement thereof.  Indemnitor shall not consent to a settlement of, or the
entry of any judgment arising from, any such Third Party Claim without the prior
written consent of Indemnitee (which consent shall not be unreasonably withheld
or delayed).  Indemnitee shall be entitled to participate in (but not control)
the defense of any such action, with its own counsel and at its own expense.

          (b)  If Indemnitor does not assume the defense of any such Third Party
Claim in accordance with the terms hereof, or if either of the conditions set
forth above in Subsection 6.4(a) is or becomes unsatisfied, the Indemnitee may
assume and actively and diligently conduct the defense of the Third Party Claim,
and such assumption shall not release the Indemnitor from any indemnification
obligation under this Section 6.4 with respect to such Third Party Claim, and
the Indemnitor may retain separate co-counsel at its sole cost and expense and
participate in the defense of the Third Party Claim, and the Indemnitee will not
consent to the entry of any judgment or enter into any settlement with respect
to the Third Party Claim without (i) the prior written consent of the Indemnitor
(such consent not to be unreasonably withheld) and (ii) obtaining a release of
the Indemnitor from such Third Party Claim.

     6.5  Attorney's Fees.  In the event of any action or proceeding brought
          ---------------                                                   
by any party against any other party in order to enforce any claim for
indemnification arising out of this Agreement, the prevailing party shall be
entitled to recover its reasonable attorney's fees incurred in such action or
proceeding, including any appeal, with the amount of such fees to be determined
by a judge of the court sitting without a jury.

     6.6  Form of Indemnification.  LSTI and the Principal Shareholders may
          -----------------------                                          
satisfy any indemnification obligations to BioLase arising under Section 6.1
(but not under Section 6.5)

                                      -22-
<PAGE>
 
hereof by delivering to BioLase Shares valued for such purposes at $3.75 per
Share.

     6.7  Limitations on Remedies and Liability.  Neither LSTI or the Principal
          -------------------------------------                                
Shareholders, on the one hand, nor BioLase, on the other hand, as indemnifying
party, shall be liable for indemnification obligations under Sections 6.1 and
6.2 hereof, respectively, (i) unless and until the aggregate amounts for which
they or it, respectively, would be liable exceed Fifty Thousand Dollars
($50,000) (and then only for such excess) (the "Basket"), or (ii) in excess of
an aggregate amount of Three Million Dollars ($3,000,000) (the "Cap"); provided,
however, that (x) the Basket shall not apply to indemnification obligations due
to or arising out of BioLase's breach of its obligations under Sections 1.2,
1.3, 1.4 (as to legal fees and disbursements only), 4.1 or 4.3 or to either
party's breach of Section 6.5, except that if BioLase uses its best efforts to
fulfill its obligations under Sections 4.1 or 4.3 and despite such efforts
indemnification obligations arise out of BioLase's breach thereof, then the
Basket applicable to such indemnification obligations shall be the lesser of
Twenty-Five Thousand Dollars ($25,000) and the then unused balance of the Basket
and (y) any claims for indemnification due to or arising out of BioLase's breach
of Sections 1.2, 1.3, 4.1 or 4.3, or either party's breach of Section 6.5
hereof, shall not be subject to the Cap.  The Principal Shareholders' liability
for indemnification hereunder shall be several, and not joint, each Principal
Shareholder shall only be responsible for one-third of each liability of LSTI
and the Principal Shareholders for indemnification hereunder, and each Principal
Shareholder's total liability for indemnification under Section 6.1 shall not
exceed One Million Dollars ($1,000,000).  The provisions of this Article VI
shall provide the exclusive remedy for any breach of any representation or
warranty, or breach of any covenant or other obligation, contained in this
Agreement; provided, however that anything in this Section 6.7 to the contrary
notwithstanding, this Section 6.7 shall not apply to, and there shall be no
limitations on, the separate indemnification obligations set forth in Section
4.1 in connection with the registration of Shares.

     6.8  Survival of Representations and Warranties.  All representations and
          ------------------------------------------                          
warranties made in this Agreement shall survive the Closing and any
investigation at any time made by or on behalf of a party hereto.
Notwithstanding the foregoing, all representations and warranties made herein
(other than the representations and warranties made in Sections 2.8 and 3.10
hereof) shall expire on March 31, 2000 and all claims for indemnification must
be brought on or before said date.  The representations made in Section 3.10
hereof shall expire upon the expiration of the applicable statute of limitations
with respect to any claims that may be asserted against LSTI and its

successors in interest in the event the matters are inaccurately set forth in

                          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."

<PAGE>
 
   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
<PAGE>
 
     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
<PAGE>
 
               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
<PAGE>
 
        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

  5.11  From and after the Effective Date, OECI agrees to indemnify and hold
        harmless BIOLASE and its officers, directors, and agents from and

        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

            (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.

         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

         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.

         harmless OECI and its officers, directors, and agents from and against

         (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;

                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

         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

         shall be in perpetuity.

   7.2.  Upon termination of the license granted herein prior to the expiration

8. BREACH OR DEFAULT

   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,
         any other rights and remedies available to OECI under law or in equity:

          i.  Specific Performance.  The right and remedy to have this Agreement
              --------------------                                              
              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

Page 7 of 10
<PAGE>
 
              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
        breach by the other, shall not be deemed to be a waiver of any other
        right or obligation provided herein, whether of a similar nature 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.

11. OBLIGATIONS TO BENEFIT OECI and BIOLASE

 11.1.  The obligations of BIOLASE under this Agreement shall be for the
        benefit of the successors and assigns of OECI.

        of the successors and assigns of BIOLASE.

            confidential, and that neither party shall publicize or disclose the
            terms of this Agreement to any other party, as except as may by
            specifically required by law.

14.  IMPOSSIBILITY OF PERFORMANCE

     14.1.  In the event that the performance by any party hereto of its
            obligations hereunder shall be interrupted or delayed by any
            occurrence not occasioned by the conduct of either party hereto,
            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.

15.  ENFORCEMENT OF AGREEMENT AND APPLICABLE LAW

     15.1  The parties submit exclusively to the jurisdiction of the state and
           federal courts located in the Commonwealth of Pennsylvania for the
           purpose of deciding all questions, disputes, or causes, including
           questions of breach of any material provision of this Agreement or
           default of any material obligation imposed on either party by this
           Agreement, whether the relief sought is injunctive relief or
           otherwise, which may arise under this Agreement. In the event BIOLASE
           or its successors or assigns is not qualified to do business in
           Pennsylvania, the Secretary of the Commonwealth of the Commonwealth
           of Pennsylvania is hereby designated as the agent of BIOLASE, its
           successors, and assigns, to accept service of process for any actions
           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
           of the Commonwealth of Pennsylvania.
