                  Loan Agreement, dated May 7, 2003, between CAP America Trust,
a trust organized under the laws of Guernsey Channel Islands, ("CAP"), and

                              W I T N E S S E T H:
                              - - - - - - - - - -

                  WHEREAS, BriteSmile wishes to borrow $2,500,000 from CAP, and
CAP 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. Definitions. Capitalized terms not otherwise defined herein shall have their
respective meanings as set forth in Section 12.

2. The Loan. (a) Subject to the terms and provisions of this Agreement, CAP
agrees to lend up to the principal amount of $2,500,000 to BriteSmile (the
"Loan"). BriteSmile has executed and delivered to CAP a promissory note (a
"Note") substantially in the form of Exhibit A hereto to evidence the Loan.

(b) BriteSmile may make drawings on account of the Loan from time to time during
the period (the "Draw Down Period") beginning on the date hereof and ending on
May 10, 2006.

(c) BriteSmile may draw on the Loan at any time and from time to time during the
Draw Down Period up to an amount of $800,000 for general working capital
purposes.

(d) BriteSmile may draw on the Loan during the Draw Down Period up to a total
amount of $1,700,000 at the times and up to the amounts specified as "costs" in
Schedule A hereto for the specific revenue generating initiatives ("SRGIs") set
forth in such Schedule. Schedule A may be amended, revised or otherwise modified
from time to time by mutual agreement of the parties hereto, and such Schedule,
as may be amended, shall be deemed a part of this Agreement.

(e) Drawings on account of working capital and SRGIs shall be made in increments
of $100,000.

(f) Drawings on account of the Loan shall be made on written notice to CAP by
BriteSmile given not less than five (5) business days prior to the date of which

<PAGE>

the draw is to be made. For drawings on account of any SRGI, BriteSmile shall
provide CAP with written documentation of all costs and expenses relating to
such SRGI no later than the date on which BriteSmile delivers written notice of
an upcoming draw pursuant to this Section 2(f).

3. Payments on Account of the Loan.

(a) Composition of Payments. The payments (the "Payments") to be made by
BriteSmile to CAP 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 CAP shall be
equal to interest on the principal balance of the Loan outstanding from time to
time based on a 360-day year at a rate (the "Target Rate") specified by CAP as
provided below which shall be either (i) six percent (6%) per annum (the "Base
Rate"), or (ii) the London Interbank Offered Rate as quoted by The Bank of Nova
Scotia for deposits in U.S. Dollars for one year maturities as determined on the
Adjustment Date plus 200 basis points (the "Libor Rate"). Initially, the Fixed
Payments shall be calculated using the Base Rate. CAP shall have the right from
time to time while the Loan remains outstanding on at least 30 days prior
written notice to BriteSmile, to set or reset the Target Rate at either the Base
Rate or the Libor Rate as of the date (the "Adjustment Date") set forth in such
notice on which such rate is to become effective. Fixed Payments will accrue
from the date of the first draw on the Loan made by BriteSmile and shall be
payable in arrears on the first business day of the month immediately following
the month during which the Fixed Payment on the Loan accrued and on the Maturity
Date. Notwithstanding the foregoing, from and after May 11, 2006, the rate of
Fixed Payments shall be calculated based on the total principal amount of the
Loan outstanding at May 11, 2006 for the period from May 11, 2006 to December
31, 2006. On January 1 of each calendar year thereafter for such calendar year
or portion thereof during which the Loan is outstanding the amount of the Fixed
Payments shall be calculated based on the total principal amount of the Loan
outstanding on such January 1.

(c) Variable Payments. Except as provided in Sections 4(b) and 4(c) of this
Agreement, BriteSmile shall pay to CAP an amount equal to $25.00 for each
BriteSmile Procedure performed at the Centers from May 11, 2006 to the Maturity
Date (the "Variable Payments"). Variable Payments shall be made on the 40th 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 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.

(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 the principal amount of the Loan which is outstanding on May 11, 2006, then
BriteSmile shall pay CAP an amount (the "Final Payment") equal to the excess of
the principal amount of the Loan outstanding on May 11, 2006 over such aggregate
amount of such Variable Payments. The Final Payment shall be made on the
Maturity Date and shall be deemed to be a payment of principal.

                                       2
<PAGE>


(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 CAP shall designate without any further notice at CAP's
address set forth below or at such other place as CAP 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 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 CAP 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 CAP 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 CAP which may be due and payable by CAP or any partner of CAP,
in accordance with law). Subject to payment (or other provision for payment
acceptable to CAP) by BriteSmile of any Other Charges due, BriteSmile shall be
permitted to contest, dispute, protest and file for refunds of any Other
Charges, and CAP 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. Except as set forth herein as to principal and interest
allocations on an Adjusted Loan, (i) the first $312,500 of Variable Payments
made with respect to the period from May 11, 2006 to December 31, 2006 shall be
deemed to be principal and (ii) the first $500,000 of Variable Payments due with
respect to any calendar year thereafter shall be deemed to be payments of
principal. (The amount of the Variable Payments that is deemed to be principal
in accordance with the preceding sentence is the "Annual Amortization Amount".)
Any excess of Variable Payments over the Annual Amortization Amount made with
respect to any calendar year shall be deemed to be payments of interest.
Notwithstanding anything to the contrary herein, if on May 11, 2006, only a
portion of the Loan has been drawn, (i) the portion of Variable Payments which
shall be deemed principal with respect to any calendar year shall be adjusted to
equal the amended Annual Amortization Amount as set forth in Section 4(c) and
(ii) any excess of Variable Payments over the amended Annual Amortization Amount
made with respect to any calendar year 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 a target number of 127 of
BriteSmile Systems installed in the Centers. However, it is recognized that the
number of BriteSmile Systems in the Centers from time to time may be greater or
less than 127 and that only 120 BriteSmile Systems are located in the Centers on
the date hereof.


                                       3


<PAGE>

(b) Adjustment. One BriteSmile Procedure performed on each of 127 BriteSmile
Systems located at the Centers would equal $3,175 of Variable Payments if the
Variable Payments were computed at a rate of $25.00 per procedure. If the actual
number of BriteSmile Systems installed at Centers varies to a number that is
either above or below 127 during any period, then a percentage adjustment to the
Variable Payment shall be made to provide that one BriteSmile Procedure
performed on each BriteSmile System at the Centers would continue to equal
$3,175 of Variable Payments. For example, if the number of BriteSmile Systems
increases to 140 then, for so long as such number remains at 140, the Variable
Payment will be reduced to $22.68 ($22.68 x 140 = $3,175). If the number of
BriteSmile Systems decreases to 115 then the Variable Payment will be increased
to $27.61 ($27.61 x 115 = $3,175). If, on May 11, 2006, when the Variable
Payments begin to accrue, there continues to be 120 BriteSmile Systems located
in the Centers, the Variable Payments at that time shall accrue at a rate of
$26.46 until thereafter adjusted pursuant to this Section 4.

(c) Less Than Full Draw Down. In the event that only a portion of the Loan has
been drawn on May 11, 2006, the Variable Payment shall be proportionally
adjusted downwards and the Annual Amortization Amount shall be amended
accordingly such that the Adjusted Loan shall be fully repaid on the Maturity
Date. For example, if only $1,500,000 of the Loan has been drawn and the number
of BriteSmile Systems located at the Centers is 127, then the Variable Payment
would be $15 ($25 x [1.5 / 2.5])per procedure and the annual amortization amount
would be $300,000 ($500,000 x [1.5 / 2.5]).

(d) Chair Adjustment and Less Than Full Draw Down. For clarification, in the
event that there is an increase or decrease above or below 127 in the number of
BriteSmile Systems installed in BriteSmile Centers and only a portion of the
Loan has been drawn down by May 11, 2006, the Variable Payment should be
adjusted as provided in both Section 4(b) and Section 4(c). For example, if the
number of BriteSmile Systems increases to 140 and only $1,500,000 of the Loan
has been drawn down by May 11, 2006, then for so long as the number of
BriteSmile Systems remains at 140, the Variable Payment will be $13.61 ([$3,175
/ 140] x [1.5 / 2.5]).

(e) 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 Centers 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 CAP
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 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.

                                       4

6. Covenants. BriteSmile covenants and agrees with CAP that until the Loan
evidenced hereby has been paid in full, unless CAP 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 CAP any such financial statements, notices,
projections and other information that CAP may reasonably request. CAP 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.

(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
(i) capital expenditures and other specific revenue generating initiatives to be
agreed and defined by BriteSmile and CAP in writing and (ii) general working
capital purposes up to $800,000.

(e) BriteSmile shall not, directly or indirectly, by operation of law, or
otherwise, merge with, consolidate with, or otherwise combine or consummate any
transaction with any person, in that would constitute a Change of Control.

(f) BriteSmile shall not mortgage, pledge or encumber the BriteSmile Systems
located at the Centers.

7. Assignment or Grant of Security Interest by CAP. BriteSmile confirms that CAP
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 CAP 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.

8. 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:

(iv) the failure by BriteSmile, within sixty days after the commencement of any

(b) Remedies of CAP Upon an Event of Default. Upon the occurrence of any one or
more Events of Default then CAP's obligation to make further advances on account
of the Loan shall immediately terminate and be of no further force or effect and
CAP, at its option, may exercise any and all rights, assert any and all claims
and pursue any and all remedies to which CAP 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 CAP shall have sustained by reason of
BriteSmile's default hereunder or on account of CAP's enforcement of its
remedies hereunder.

(c) BriteSmile shall reimburse CAP for all costs and expenses incurred in
connection with the enforcement of any right or remedy hereunder, including
attorneys' fees.

9. Reports; Representations and Warranties of BriteSmile .

provide a written statement of the address of each Center where a BriteSmile

have been paid by BriteSmile in connection with the loan evidenced by Agreement
