                             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
observance of any other covenant, term or condition hereof or the inaccuracy in

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

                                       10<PAGE>

                                                                   Exhibit 10.46

                      RESTRICTED STOCK PURCHASE AGREEMENT

          This Agreement is made as of September 29, 2000 by and between FIRETAP
COMMUNICATIONS INCORPORATED, a Delaware corporation (the "Company") and
Catherine Hapka, the Chief Executive Officer of RHYTHMS NETCONNECTIONS, INC., a
Delaware corporation (Catherine Hapka, the "Purchaser").

          In consideration of the covenants, representations and considerations
set forth in this Agreement, the parties to this Agreement hereby agree as
follows:

                             1. PURCHASE OF SHARES

1.1  Purchase.  The Purchaser hereby agrees to purchase from the Company, and
     the Company hereby agrees to sell and issue to the Purchaser, a number of
     Shares (the "Purchased Shares") equal to one and one-half percent (1 1/2%)
     of the total outstanding shares of Company on a fully-diluted basis as of
     the conclusion of the first round of financing for Company which ended in
     approximately April, 2000 (the "First Round"), which one and one half
     percent (1 1/2 %) shall be calculated on a post-money basis in respect of
     the First Round without regard to subsequent issuances of shares. The total
     number of shares issued under this Agreement, the Restricted Stock Purchase
     Agreement dated as of the date hereof between Rhythms Netconnections, Inc.
     ("Rhythms") and Company and the Service Agreement dated as of the date
     hereof between Rhythms and Company shall be up to 5% of the total
     outstanding shares of Company on a fully-diluted basis as of the conclusion
     of the First Round, which 5% shall be calculated on a post-money basis in
     respect of the First Round without regard to subsequent issuances of
     shares. The Purchased Shares shall be issued pursuant to Company's employee
     and director stock option plan (the "Plan") once it is adopted by Company.
     Company agrees to use commercially reasonable efforts to adopt the Plan
     within a commercially reasonable time period.

1.2  Payment.  The Purchaser shall purchase the Purchased Shares by (i) payment
     of $0.001 for each Purchased Share on the date hereof, and (ii) providing
     the continuing services of the Director, subject to the terms and
     conditions contained herein ("Purchase Price").

1.3  Issuance of Shares.  The Purchased Shares shall be issued within 30 days'
     of the adoption of the Plan.

1.4  Stockholder Rights.  Until such time as the Company actually exercises its
     Repurchase Rights (as defined herein) under this Agreement, if ever, the
     Purchaser (or any successor in interest) is entitled to all the rights of a
     stockholder with respect to the Purchased Shares, subject, however, to the
     restrictions of this Agreement and the Company's Stockholders Agreement,
     dated as of May 15, 2000, as may be amended from time to time (the
     "Stockholders Agreement").

                               2. SECURITIES LAW
<PAGE>

2.1  Investment Intent.  The Purchaser hereby warrants and represents that the
     Purchaser will acquire the Purchased Shares for the Purchaser's own account
     and not with a view to their resale or distribution.

2.2  Exemption from Registration.  The Purchaser acknowledges that the Purchased
     Shares will not be registered under the Securities Act of 1933, as amended
     (the "1933 Act"), and will be issued in reliance upon an exemption from
     such registration.

2.3  Restricted Securities.  The Purchaser hereby confirms that the Purchaser
     has been informed that the Purchased Shares will be restricted securities
     under the 1933 Act and may not be resold or transferred unless the
     Purchased Shares are first registered under the Federal securities laws or
     unless an exemption from such registration is available.  Accordingly, the
     Purchaser hereby acknowledges that the Purchaser is prepared to hold the
     Purchased Shares for an indefinite period and that the Purchaser is aware
     that Rule 144 of the Securities and Exchange Commission issued under the
     1933 Act is not presently available to exempt the sale of the Purchased
     Shares from the registration requirements of the 1933 Act.

2.4  Disposition of Shares.  The Purchaser hereby agrees that the Purchaser may
     not make any disposition of the Purchased Shares other than in accordance
     with the Plan, the Stockholders Agreement and all applicable securities
     laws.  The Company will not be required:

     (A)  to transfer on its books any Purchased Shares which have been sold or
          transferred in violation of the provisions of this Section 2; nor

     (B)  to treat as the owner of the Purchased Shares, or otherwise to accord
          voting or dividend rights to, any transferee to whom the Purchased
          Shares have been transferred in contravention of this Agreement.

2.5  Restrictive Legends.  In order to reflect the restrictions on disposition
     of the Purchased Shares, the stock certificates for the Purchased Shares
     will be endorsed with the following restrictive legend:

               (i)    "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
          SUBJECT, PURSUANT TO A CERTAIN STOCKHOLDERS AGREEMENT AMONG FIRETAP
          COMMUNICATIONS INCORPORATED (THE "COMPANY"), HOMESTORE.COM, INC. AND
          CERTAIN OF THE COMPANY'S STOCKHOLDERS, TO CERTAIN RIGHTS AND
          RESTRICTIONS ON TRANSFER SET FORTH IN THE STOCKHOLDERS AGREEMENT. A
          COPY OF SUCH STOCKHOLDERS AGREEMENT WILL BE FURNISHED WITHOUT CHARGE
          BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST TO THE
          SECRETARY OF THE COMPANY.

               (ii)   THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
          TO THE TERMS AND CONDITIONS OF A CERTAN RESTRICTED STOCK PURCHASE
          AGREEMENT BETWEEN THE

                                       2
<PAGE>

          COMPNY AND THE REGISTERED HOLDER HEREOF WHICH INCLUDES A RIGHT OF
          REPURCHASE. A COPY OF SUCH RESTRICTED STOCK PURCHASE AGREEMENT WILL BE
          FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON
          WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY.

               (iii)  THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES
          ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND MAY NOT BE OFFERED
          OR SOLD UNLESS IT HAS BEEN REGISTERED UNDER THE SECURITIES ACT OR
          UNLESS AN EXEMPTION FROM REGISTRATION IS AVAILABLE (AND, IN SUCH CASE,
          AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY SHALL
          HAVE BEEN DELIVERED TO THE COMPANY TO THE EFFECT THAT SUCH OFFER OR
          SALE IS NOT REQUIRED TO BE REGISTERED UNDER THE SECURITIES ACT)."

2.6  Nature of Purchaser.  The Purchaser hereby warrants and represents that the
     Purchaser is and will be at the time of purchase an "Accredited Investor"
     as that term is defined in Rule 501(a) of Regulation D adopted by the
     Securities and Exchange Commission under the Securities Act of 1933 (17 CFR
     Sec. 230.501(a)).

                           3. TRANSFER RESTRICTIONS

3.1  Restriction on Transfer.  The Purchaser may not transfer, assign, encumber,
     or otherwise dispose of any of the Purchased Shares that are subject to the
     Company's Repurchase Right under Section 4 and pursuant to such Repurchase
     Right.

                   4. VESTING SCHEDULE AND REPURCHASE RIGHT

4.1  Vesting Schedule.  On the date of the first anniversary of the issuance of
     the Purchased Shares, 33% of the Purchased Shares shall be considered
     "Vested Shares" and the remainder shall be considered "Unvested Shares."
     On the date of the second anniversary hereof, an additional 33% of the
     Purchased Shares shall become Vested Shares.  Finally, on the date of the
     third anniversary hereof, the remaining 34% of the Purchased Shares shall
     become Vested Shares.

4.2  Repurchase Rights Based on Services of Catherine Hapka.

     (A)  If Catherine Hapka is not a member of the Company's Board of
          Directors, whether voluntarily or involuntarily (A) due to a permanent
          disability of Catherine Hapka rendering her unable to continue working
          for the Company's Board of Directors, (B) due to the Board of
          Directors or the stockholders of the Company removing her from the
          Board of Directors with Cause (as defined below), or (C) due to the
          Board of Directors or the stockholders of the Company voting not to
          elect or re-elect Catherine Hapka to the Board of Directors because
          she has engaged in any conduct which constitutes Cause for removal,
          then the Company will have the option (the "Repurchase Right"),
          exercisable within 30 days of such event by notice to the Purchaser or
          the Purchaser's legal

                                       3
<PAGE>

          representatives, heirs, legatees, distributees, assigns or
          transferees, to repurchase from the Purchaser (unless prohibited by
          any applicable law) all of the Unvested Shares of Purchased Shares
          owned by the Purchaser at the purchase price of $0.10 per share (the
          "Repurchase Price").

     (B)  Notwithstanding anything to the contrary in this Agreement, any
          Unvested Shares of Purchased Shares shall immediately vest if the
          Board of Directors or the Company's shareholders remove or do not re-
          elect Catherine Hapka without having Cause.

          For the purposes of this Agreement, "Cause" shall mean that the
          Company, acting in good faith based upon the information then known to
          the Company, determines that Catherine Hapka has engaged in or
          committed: willful misconduct; gross negligence; theft, fraud or other
          illegal conduct; refusal or unwillingness to perform her duties;
          sexual harassment; conduct which reflects adversely upon, or making
          any remarks disparaging of, the Company, its Board, officers,
          directors, advisors or employees or its affiliates or subsidiaries;
          insubordination; any willful act that is likely to and which does in
          fact have the effect of injuring the reputation, business or a
          business relationship of the Company; violation of any fiduciary duty
          to Company; violation of any duty of loyalty to Company; and breach of
          any term of this Agreement.

                             5. GENERAL PROVISIONS

5.1  Assignment.  The Company may, at its option, assign its Repurchase Right

     to this Agreement.

5.3  No Waiver.  The failure of the Company (or its assignees) in any instance
     to exercise the Repurchase Right granted under Section 4 will not
     constitute a waiver of any other repurchase rights and/or rights of first
     refusal that may subsequently arise under the provisions of this Agreement,
     the Plan or any other agreement between the Company and the Purchaser.  No
     waiver of any breach or condition of this Agreement will be deemed to be a
     waiver of any other or subsequent breach or condition, whether of like or
     different nature.

     at the time and place and in the amount and form provided in this
     Agreement, the consideration for the Purchased Shares to be repurchased in
     accordance with the provisions of this Agreement, then from and after such
     time, the Purchaser will no longer have any rights as

                                       4
<PAGE>

     a holder of such shares (other than the right to receive payment of such
     consideration in accordance with this Agreement), and such shares will be
     deemed purchased in accordance with the applicable provisions hereof and
     the Company (or its assignees) will be deemed the owner and holder of such
