                             NOTE PURCHASE AGREEMENT

         This Note Purchase Agreement ("Agreement") is made and entered into as
of the 20th day of November, 2002 by and between BriteSmile, Inc., a Utah
corporation ("BriteSmile" or the "Company") and LCO Investments Limited
("Purchaser").

         A.       Pursuant to that certain Guarantee of Fiscal 2002 Shortfall
                  agreement between the Company and Purchaser effective March 4,
                  2002, the Company desires to borrow Two Million Five Hundred
                  Thousand Dollars ($2,500,000) from Purchaser and Purchaser
                  desires to lend $2,500,000 to the Company; and

         B.       In consideration of the loan amount, the Company has
                  authorized the    issuance to Purchaser of a Convertible
                  Promissory Note in the original principal amount of $2,500,000
                  (the "Note").

         NOW THEREFORE, in consideration of the mutual promises and covenants
contained in this Agreement, and other valuable consideration, the receipt of
which is hereby acknowledged, the parties covenant and agree as follows:

         1. Loan and Note Purchase. The Company agrees to borrow Two Million
Five Hundred Thousand Dollars ($2,500,000) from Purchaser and Purchaser agrees
to lend to the Company $2,500,000 (the "Loan") pursuant to the terms and
conditions of this Agreement and the Note, a copy of which is attached to this
Agreement as Exhibit "A" and by this reference incorporated herein. Purchaser
agrees to purchase the Note and tenders herewith the principal amount of the
Loan, receipt of which by the Company is hereby acknowledged. Principal and
interest owing under the Note is convertible into shares of Common Stock, par
value $.001 per share, of the Company ("Common Stock"), at a conversion price
equal to $0.40 per share, the closing sale price of Common Stock as quoted on
NASDAQ on the effective date of this Agreement. The total purchase price (the
"Purchase Price") for the Note shall be Two Million Five Hundred Thousand
Dollars ($2,500,000). The Purchaser shall pay the Purchase Price in full at
Closing, as hereinafter defined, via wire transfer to an account of the Company
identified by the Purchaser and under the control of persons designated by or


                                       1

acceptable to the Purchaser on or before the Closing Date. Wire instructions
shall be provided prior to the Closing. The Note, together with the shares of
Common Stock into which the Note may be converted (the "Shares"), shall be
referred to collectively in this Agreement as the "Securities."

         2. Registration Rights and Note Conversion. The Shares shall be subject
to certain registration rights, as provided in that certain Registration Rights
Agreement dated as of March 4, 2002 (the "Registration Rights Agreement"),
between Purchaser and the Company, a copy of which is attached hereto as Exhibit
"B". The Registration Rights Agreement is hereby amended to include the Shares
as registrable securities under Sections 1 and 2 thereof. (Such Registration
Rights Agreement, as amended hereby, together with this Agreement and the Note
constitute the "Transaction Documents"). In addition, BriteSmile shall make
appropriate filings under the rules of Nasdaq in order that the Shares will be
authorized for listing on Nasdaq, subject to notice of issuance upon conversion.
Conversion shall further be conditioned upon the Company having sufficient
authorized capital stock to effect the conversion, and upon compliance with all
applicable regulatory and securities law requirements.

         3. Closing. Payment of the Purchase Price by the Purchaser and delivery
of the Note and Registration Rights Agreement by BriteSmile shall be deemed to
be the completion of the transactions contemplated by this Agreement
("Closing"). Closing shall occur concurrently with the execution of this
Agreement, effective as of the date hereof, or on such later date as the parties
may hereafter agree (the "Closing Date").

         4.       Use and Disposition of Proceeds.  The Loan proceeds will be
used in the manner directed by the Company's Board of Directors,  or as shall be
determined or directed pursuant to authority delegated by the Board.

         5.       Representations and Warranties of Purchaser.  Purchaser hereby
represents and warrants to the Company and its agents and attorneys as follows:

                  5.1      Investor Status.  Purchaser is an "accredited
         investor"  within the meaning of Section  501(a) of Regulation D under
         the Act, or is not a "U.S.  Person" as that term is defined under Rule
         902(o)(1) of Regulation S under the Act.

                  5.2 Liquidity. Purchaser presently has sufficient liquid
         assets to pay the Purchase Price. Purchaser has adequate means of
         providing for its current needs and contingencies and has no need for
         liquidity in its investment in the Company or for a source of income
         from the Company. Purchaser is capable of bearing the economic risk and
         the burden of the investment contemplated by this Agreement, including,
         but not limited to, the possibility of the complete loss of the value
         of the Securities, and the limited transferability of the Securities,
         which may make the liquidation of the Securities impossible in the near
         future.

         binding on Purchaser, or the provision of any indenture, instrument or
         agreement to which Purchaser is a party or is subject, or by which
         Purchaser or any of its properties is bound, or conflict with or
         constitute a material default thereunder, or result in the creation or
         imposition of any lien pursuant to the terms of any such indenture,
         instrument or agreement, or constitute a breach of any fiduciary duty
         owed by such Purchaser to any third party, or require the approval of
         any third-party pursuant to any material contract, agreement,
         instrument, relationship or legal obligation to which Purchaser is
         subject or to which any of its properties, operations or management may
         be subject.

                  5.5 Sole Party in Interest. Purchaser represents that it is
         the sole and true party in interest, and no other person or entity has
         or will have upon the issuance of the Securities beneficial ownership
         interest in the Securities or any portion thereof, whether direct or
         indirect (excluding any contractual right to payments based on the
         value of such Securities), other than the equity holders or
         beneficiaries of Purchaser or as set forth on Purchaser's Reports on
         Schedule 13D or Forms 4 with respect to the Securities.

                  5.6.     Investment Purpose.  Purchaser represents that it is
         acquiring  the  Securities  for its  own  account  and for  investment
         purposes  and not for the  account or  benefit of any other  person or
         entity or for or with a view to resale or distribution.

                  5.7 Knowledge and Experience. Purchaser is experienced in
         evaluating and making speculative investments, and has the capacity to
         protect Purchaser's interests in connection with the acquisition of the
         Securities. Purchaser has such knowledge and experience in financial
         and business matters in general, and investments in the Company in
         particular, that Purchaser is capable of evaluating the merits and
         risks of Purchaser's investment in the Company.

Company,   including  those  disclosed  in  documents   incorporated  herein  by

solicited  by or through any leaflet,  public  promotional  meeting,  television
advertisement or any other form of general solicitation or advertising.

         8. Restricted Securities. Purchaser understands and acknowledges that
the Securities have not been registered under the Act, or any state securities
laws, and that they will be issued in reliance upon certain exemptions from the
registration requirements of those laws, and thus cannot be resold unless they
are registered under the Act or unless the Company has first received an opinion
of competent securities counsel that registration is not required for such
resale. Purchaser agrees that it will not resell any Securities unless such
resale transaction is in accordance with Regulation S and/or Rule 144 under the
Act, pursuant to registration under the Act, or pursuant to an available
exemption from registration. With regard to the restrictions on resales of the
Securities or any security underlying or into which the Securities are or may be
convertible, Purchaser is aware (i) of the limitations and applicability of
Securities and Exchange Commission Rule 144, (ii) that the Company will issue
stop transfer orders to its stock transfer agent in the event of attempts to
improperly transfer any such securities; and (iii) that a restrictive legend
will be placed on certificates representing the Securities and any security
underlying or into which any of the Securities are or will be convertible, which
legend will read substantially as follows:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ISSUED
         PURSUANT TO A CLAIM OF EXEMPTION FROM THE REGISTRATION OR QUALIFICATION
         PROVISIONS OF THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND
         STATE SECURITIES LAWS AND THEREFORE HAVE NOT BEEN REGISTERED UNDER THE
         ACT OR UNDER THE SECURITIES LAWS OF ANY STATE. THESE SECURITIES MAY NOT
         BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR HYPOTHECATED WITHOUT

         144 UNDER THE ACT, COMPLIANCE WITH THE REGISTRATION OR QUALIFICATION
         PROVISIONS OF THE ACT OR APPLICABLE STATE LAWS, OR PURSUANT TO AN
         AVAILABLE EXEMPTION FROM SUCH REGISTRATION REQUIREMENTS. THE COMPANY
         WILL INSTRUCT ITS STOCK TRANSFER AGENT NOT TO RECOGNIZE ANY SALE OF
         THESE SECURITIES UNLESS SUCH SALE IS MADE PURSUANT TO AN EFFECTIVE
         REGISTRATION STATEMENT UNDER THE ACT OR THE COMPANY HAS FIRST RECEIVED
         AN OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY AND ITS SECURITIES
         COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.
