                             LOAN AGREEMENT BETWEEN

                              AND BRITESMILE, INC.

          Loan Agreement, dated March 1, 2001, between Excimer Vision Leasing
L.P., a Delaware limited partnership ("EVL"), and BriteSmile, Inc., a Utah
corporation ("BriteSmile").

                              W I T N E S S E T H:
                              -------------------
          WHEREAS, BriteSmile wishes to borrow $2,500,000 from EVL, and EVL
wishes to lend $2,500,000 to BriteSmile on the terms and conditions set forth
herein.

          NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto, intending to be
bound hereby, do hereby agree as follows.

          1.   Definition. Capitalized terms not otherwise defined herein shall
               ----------
have their respective meanings as set forth in Section 12.

          2.   The Loan. Subject to the terms and provisions of this Agreement,
               --------
EVL agrees to lend the principal amount of $2,500,000 to BriteSmile on March 12,
2001 (the "Loan"). BriteSmile will execute and deliver to EVL a promissory note
(a "Note") substantially in the form of Exhibit A hereto to evidence the Loan.

          3.   Payments on Account of the Loan.
               -------------------------------

               (a)  Composition of Payments. The payments to be made by
                    -----------------------
BriteSmile to EVL on account of the Loan will be comprised of Fixed Payments,
Variable Payments and the Final Payment.

               (b)  Fixed Payments. The Fixed Payments to be made by BriteSmile
                    --------------
to EVL shall be made at a rate equal to $150,000 per year payable in the amount
of $10,416.60 on April 1, 2001 and thereafter in equal monthly increments of
$12,500 each on the first day of each month during the term of the Loan up to
and including May 1, 2006. A final Fixed Payment of $3,750.00 shall be due and
payable on the Maturity Date.

               (c)  Variable Payments. The amount of Variable Payments to be
                    -----------------
made by BriteSmile to EVL shall be an amount equal to $25.00 for each BriteSmile
Procedure performed at the Existing Centers from March 1, 2001 to the Maturity
Date. Variable Payments shall be made on the 40/th/ day following the end of
each month up to and including the month in which the Maturity Date occurs based
on the number of BriteSmile Procedures performed at the Existing Centers during
such month, except that any Variable Payments due with respect to any period
prior to the date on which the Maturity Date occurs shall be made on the
Maturity Date.

<PAGE>

               (d)  Final Payment. In the event that the aggregate amount of
                    -------------
those Variable Payments which are deemed to be payments of principal under
subsection 3(g) hereof and which are actually made up to and including the
Maturity Date is less than $2,500,000, then BriteSmile shall pay EVL an amount
(the "Final Payment") equal to the excess of $2,500,000 over such aggregate
amount of Variable Payments. The Final Payment shall be made on the Maturity
Date and shall be deemed to be a payment of principal.

               (e)  Method of Payment. Fixed Payments, Variable Payments and the
                    -----------------
Final Payment shall be payable on the date due by wire transfer, electronic
direct deposit or such other method as EVL shall designate without any further
notice at EVL's address set forth below or at such other place as EVL shall
designate in writing. Payments shall be paid free and clear of all claims,
demands or setoffs of any nature whatsoever.

               (f)  Other Charges. BriteSmile's obligation to pay all amounts
                    -------------
payable by BriteSmile hereunder shall be absolute and unconditional and shall
not be subject to any abatement, reduction, set-off, defense, counterclaim,
interruption, deferment or recoupment for any reason whatsoever, and that such
payments shall be and continue to be payable by BriteSmile in all events.
BriteSmile shall pay when due or reimburse and indemnify and hold EVL harmless
(on a net after-tax basis) from and against all taxes, fees or other charges
(collectively, the "Other Charges") of any nature whatsoever now or hereafter
imposed or assessed during the term hereof against EVL by any federal, state,
county, or local governmental authority upon or with respect to Payments
hereunder (excepting only federal, state and local taxes based on or measured by
the net income of EVL which may be due and payable by EVL or any partner of EVL,
in accordance with law). Subject to payment (or other provision for payment
acceptable to EVL) by BriteSmile of any Other Charges due, BriteSmile shall be
permitted to contest, dispute, protest and file for refunds of any Other
Charges, and EVL shall reasonably cooperate with any such contest, dispute,
protest or application for refund.

               (g)  Allocations. The following principles shall apply for
                    -----------
purposes of determining what portion of the Payments shall be deemed to be
payments of interest and payments of principal. Fixed Payments shall be deemed
to be payments of interest. The first $416,667 of any Variable Payments due with
respect to the period from March 1, 2001 to December 31, 2001 and the first
$500,000 of Variable Payments due with respect to any calendar year thereafter
shall be deemed to be payments of principal. Any excess of Variable Payments
over $416,667 made with respect to the period ending December 31, 2001 and over
$500,000 made with respect to any year beginning after December 31, 2001 shall
be deemed to be payments of interest. The Final Payment shall be deemed to be a
payment of principal.

          4.   Additional Provisions Relating to Calculation of Variable
               ---------------------------------------------------------
Payments.
--------

               (a)  Existing Systems. It is intended that the Variable Payments
                    ----------------
be computed with reference to BriteSmile Procedures performed on the actual
number of BriteSmile Systems that are installed in the Existing Centers from
time to time. It is recognized that the number of BriteSmile Systems in Existing
Centers from time to time may be greater or less than the 127 BriteSmile Systems
located in the Existing Centers on the date hereof and that the number of
BriteSmile Procedures included in the calculation of the Variable Payments may
be affected if BriteSmile Systems are added to or removed from Existing Centers.

                                       2
<PAGE>

               (b)  Surrogate Systems. If, however, the actual number of
                    -----------------
BriteSmile Systems installed at Existing Centers declines to below 127 during
any period, and if any BriteSmile Systems are installed at a New Center during
such period, then EVL may elect to include the BriteSmile Procedures performed
on some or all of the New Systems (the "Surrogate Systems") in the calculation
of Variable Payments due provided that the maximum number of such Surrogate
Systems that may be designated at any time shall not exceed the difference
between 127 and the number of BriteSmile Systems in the Existing Centers at such
time.

               (c)  Best Efforts. BriteSmile shall use reasonable commercial
                    ------------
efforts to ensure that all BriteSmile Systems that are designated as Surrogate
Systems from time to time and are used throughout their respective periods of
designation as such so that the Variable Payments due with respect to each
Surrogate System can achieve its maximum potential.

               (d)  No Right to Income from Centers. The parties acknowledge
                    -------------------------------
that BriteSmile only manages the dental practices conducted at the Centers and
that it does not have any partnership or other equity or ownership interest in
such practices. The parties further acknowledge that BriteSmile receives a
management fee for its services in managing the Center and has no right to share
in any item of revenue received by the Centers. Accordingly, it is expressly
acknowledged that the Variable Payments do not represent any division between
BriteSmile and EVL of revenue earned by any Center. It is agreed that the use of
BriteSmile Procedures performed at the Centers as a method to calculate Variable
Payments represents no more than a convenient method to determine the timing and
amount of payments of principal and contingent interest due hereunder and is not
intended as a means to share in BriteSmile's management fees for operating the
Centers.

          5.   No Prepayment. BriteSmile may not prepay all or any part of the
               -------------
Note at any time.

          6.   Other Indebtedness. The indebtedness represented by this Note is
               ------------------
intended to be pari passu with the indebtedness represented by the Promissory
Notes issued pursuant to the Securities Purchase Agreement, dated August 3,
2000, between BriteSmile and the Purchasers named therein.

          7.   Covenants. BriteSmile covenants and agrees with EVL that until
               ---------
the Loan evidenced hereby has been paid in full, unless EVL shall otherwise
consent in writing:

               (a)  BriteSmile shall do or cause to be done all things necessary
to preserve, renew and keep in full force and effect its existence.

               (b)  BriteSmile shall deliver to EVL any such financial
statements, notices, projections and other information that EVL may reasonably
request. EVL shall treat any such information which is not publicly available as
confidential and shall not disclose any such confidential information to any
third party or use any such confidential information for any purpose other than
in connection with this Agreement.

                                       3
<PAGE>

               (c)  BriteSmile agrees to, at its sole cost and expense, continue
to manage the operations of at least ten Centers in substantially the same
manner as the operations of the Centers are conducted on the date hereof.

               (d)  The proceeds of the Loan evidenced hereby shall be used by
BriteSmile for general working capital purposes.

               (e)  BriteSmile shall not, directly or indirectly, by operation
of law, or otherwise, merge with, consolidate with, or otherwise combine with
any person, unless this Agreement and the Note is assumed by such person
pursuant to such merger, consolidation or other combination.

          8.   Assignment or Grant of Security Interest by EVL. BriteSmile
               -----------------------------------------------
confirms that EVL may sell and assign its rights and obligations under this
Agreement to an assignee (the "Assignee") or grant a security interest in this
Agreement to a security assignee (the "Secured Party"). BriteSmile agrees it
will cooperate with EVL to facilitate each such assignment and grant of a
security interest. Notwithstanding the foregoing, without BriteSmile 's consent,
no Assignee or Secured Party may be engaged directly or indirectly in the
business of whitening teeth at the time that any assignment or the grant of any
security interest occurs.

          9.   Concerning Defaults.
               -------------------

               (a)  Events of Default. The occurrence of any one or more of the
                    -----------------
following events ("Events of Default") shall constitute a default hereunder:

                    (ii)   default by BriteSmile in the performance or

or in any document or certificate furnished to EVL in connection herewith, which
default or inaccuracy shall continue for a period of ten days after notice to
BriteSmile thereof;

                    (iii)  the making of an assignment by BriteSmile for the
benefit of its creditors or the admission by BriteSmile in writing of its
inability to pay its debts as they become due, or the insolvency of BriteSmile ,
or the filing by BriteSmile of a voluntary petition in bankruptcy, or the
adjudication of BriteSmile as a bankrupt, or the filing by BriteSmile of any
petition or answer seeking for itself any reorganization, arrangement,
composition, readjustment, liquidation, dissolution, or similar relief under any
present or future statute, law or regulation, or the filing of any answer by
BriteSmile admitting or the failure by BriteSmile to deny, the material
allegations of a petition filed against it for any such relief, or the seeking
or consenting of BriteSmile to, or acquiescence by BriteSmile in, the
appointment of any trustee, receiver or liquidator of BriteSmile or of all or
any substantial portion of the properties of BriteSmile , or the inability of
BriteSmile to pay its debts when due, or the commission by BriteSmile of any act
of bankruptcy as defined in the Federal Bankruptcy Act, as amended; or

commencement of any proceeding against BriteSmile seeking any reorganization,
arrangement, composition, readjustment, liquidation, dissolution or similar
relief under any present or future statute, law or regulation, that will cause
BriteSmile to default under the events stipulated above in Section 11(b),
subsections (i), (ii), or (iii), to obtain dismissal of such proceeding or,
within 60 days after the appointment, without the consent or acquiescence of
BriteSmile , of any trustee, receiver or liquidator of BriteSmile or of all or
any substantial part of the properties of BriteSmile , to vacate such
appointment.

               (b)  Remedies of EVL Upon an Event of Default. Upon the
                    ----------------------------------------
occurrence of any one or more Events of Default, EVL, at its option, may
exercise any and all rights, assert any and all claims and pursue any and all
remedies to which EVL may be entitled by law and may

                    (i)    accelerate the maturity of this Loan and declare all
amounts due hereunder including, but not limited to, the Final Payment, to be
immediately due and payable; and

                    (ii)   proceed by appropriate court action to enforce
performance by BriteSmile of the applicable terms hereof and recover from
BriteSmile any and all damages and expenses, including attorneys' fees, which
EVL shall have sustained by reason of BriteSmile's default hereunder or on
account of EVL's enforcement of its remedies hereunder.

               (c)  BriteSmile shall reimburse EVL for all costs and expenses
incurred in connection with the enforcement of any right or remedy hereunder,
including attorneys' fees. Except as set forth in this Section and to the extent
permitted by applicable law, BriteSmile hereby waives any rights now or
hereafter conferred by statute or otherwise which may limit or modify any of
EVL's rights or remedies.

          10.  Reports; Representations and Warranties of BriteSmile.
               -----------------------------------------------------

               (a)  Reports. At such times as EVL may reasonably request,
                    -------
BriteSmile shall provide a written statement of the address of each Center where
a BriteSmile System is installed or stored. In addition, together with each
payment of Variable Rent, BriteSmile shall provide a written report to EVL, in a
format reasonably acceptable to EVL and BriteSmile, indicating the BriteSmile
Procedures performed with respect to which Variable Rent is due. EVL shall have
the right throughout the term of this Agreement, upon at least 30 days' written

conflict with BriteSmile 's certificate of incorporation or by-laws or any law,
rule or regulation or agreement to which it is subject and by which its assets
are bound.

          11.  Usury. Anything in this Agreement or the Note to the contrary
               -----
notwithstanding, if due to any circumstances whatsoever, fulfillment of any
provision of Agreement or the Note shall involve transcending the limit of
validity prescribed by the usury laws of the State of New York or the laws of
any other jurisdiction which might be applicable hereto, then ipso facto the
obligation to be fulfilled under Agreement or the Note shall be reduced to the
limit of such validity so that in no event shall exaction be possible under

obligation shall be fulfilled to the limit of such validity and if under any

have been paid by BriteSmile in connection with the loan evidenced by Agreement
or the Note, such excess shall be applied by the holder hereof to the unpaid
principal balance of this Agreement or the Note or refunded to BriteSmile, the
manner of handling such excess to be at the election of the holder hereof so
