        F. In connection with the Building 3 Lease, M-F Downtown and Handspring
entered into that certain Work Letter (Building 3) (as the same has been amended
by the parties prior to the date hereof, the "Building 3 Work Letter") governing

Dollars ($14,200,000).

        G. As contemplated by the Building 2 Lease and the Building 3 Lease
(collectively, the "Leases") and by the Building 2 Work Letter and the Building
3 Work Letter (collectively, the "Work Letters"), Bank of America, N.A., as
administrative agent for M-F Downtown's construction lenders (collectively, the
"Construction Lenders") (Bank of America, N.A., acting in such capacity being
referred to herein as ("Bank of America"), has become the beneficiary under the
Building 2 Security Deposit Letter of Credit and the Building 3 Security Deposit
Letter of Credit (collectively, the "Security Deposit Letters of Credit") and
under the Building 2 TI Letter of Credit and the Building 3 TI Letter of Credit
(collectively, the "TI Letters of Credit" and, together with the Security
Deposit Letters of Credit, the "Letters of Credit"). Neither the Building 2
Security Deposit Letter of Credit nor the Building 3 Security Deposit Letter of
Credit has been drawn upon by M-F Downtown or Bank of America. In accordance
with the terms of the Building 2 Work Letter, the principal amount of the

M-F Downtown or Bank of America.

        H. In light of the current business cycle and the local market for
commercial real estate leasing and sub-leasing, Handspring has requested that
M-F Downtown provide Handspring with significant economic relief under the terms
of the Buildings 2 Lease and the Building 3 Lease (collectively, the "Leases").
On careful analysis, Handspring has concluded that if the parties can agree on
terms for modifying the Leases, Handspring will benefit both as to the
immediately quantifiable economic relief bargained for and as to the opportunity
afforded Handspring to thereby continue its business.


                                       -2-

        I. In light of the current business cycle and the local market for
commercial real estate leases and sub-leasing, M-F Downtown is willing to enter
into a material restructuring of the Leases, but only if the transaction is
economically balanced, fair in fact and on arms' length terms.

        J. The parties have agreed to co-operate in the form of a unified
transaction involving the restructuring of the Leases in a manner which includes
the sale of Building 3 by M-F Downtown in order to provide Handspring with the
requested economic relief, to minimize financial loss to the parties, and to
adopt a single, integrated structure that will enable Handspring to perform its
modified obligations to M-F Downtown, while minimizing the risk to M-F Downtown
should Handspring subsequently be unwilling or unable to so perform. In order to
accomplish such restructuring, Handspring, HFC and Mozart have entered into a
Property Purchase and Lease Modification Agreement dated as of January 16, 2003.

herein as the "Transaction".

                therewith, to give such discharges or releases as M-F Downtown
                may deem reasonably appropriate; and (VII) generally to sell,
                make any agreement with respect to or otherwise deal with any of
                the Collateral as fully and completely as though M-F Downtown
                were the absolute owner thereof for all purposes, and to do, at
                M-F Downtown's option and HFC's expense, at any time, or from
                time to time, all acts and things which M-F Downtown reasonably
                deems necessary to protect, preserve or realize upon the
                Collateral and M-F Downtown's Lien therein, in order to effect
                the intent of this Assignment Agreement, all as fully and
                effectively as HFC might do; and

                                (D) to receive any and all distributions paid in
                respect of the Collateral and to make application thereof to the
                Obligations, and M-F Downtown or its nominee may exercise any
                and all rights, privileges or options pertaining to the
                Collateral as if it were the absolute owner thereof, all without
                liability except to account for property actually received by
                it, but M-F Downtown shall have no duty to exercise any such
                right, privilege or option and shall not be responsible for any
                failure to do so or delay in so doing.

                        (ii) The powers conferred on M-F Downtown hereunder are
        solely to protect M-F Downtown's interests in the Collateral and shall
        not impose any duty upon it to exercise any such powers. M-F Downtown
        shall be accountable only for amounts that it actually receives as a
        result of the exercise of such powers and neither it nor any of its
        officers, directors, employees, attorneys, or agents shall be
        responsible to HFC for any act or failure to act, except for its own
        gross negligence or wilful misconduct.

                        (iii) HFC also authorizes M-F Downtown, at any time and
        from time to time upon the occurrence and during the continuation of an
        Event of Default, to execute, in connection with the sale provided for
        in Section 5 hereof, any endorsements, assignments or other instruments
        of conveyance or transfer with respect to the Collateral.

        5. DEFAULT.

                (a) DEFAULT; EVENTS OF DEFAULT. HFC agrees that the occurrence
of the following, together with the expiration of any applicable notice and/or
cure period (if any), shall constitute an "Event of Default" under this
Assignment Agreement:

<PAGE>
                        (i) If a default occurs under the Obligation Documents;
        or

                        (ii) If HFC fails to pay any fees, costs or other
        amounts as and when required to be paid under this Assignment Agreement
        within three (3) business days after written demand by M-F Downtown; or

                        (iii) If M-F Downtown shall cease to have a first
        priority security interest in any of the Collateral or if HFC violates
        Section 3(k) hereof; or

                        (iv) If HFC takes any action or permits any action to be
        taken that is reasonably likely to, or does, materially and irreparably
        impair the value of the Collateral; or

                        (v) If a bankruptcy case or other arrangement,
        composition or reorganization proceeding of any kind is filed by or
        against HFC; provided, however, that in the event of the filing of an
        involuntary bankruptcy petition, such Default may be cured by obtaining
        dismissal of such petition with sixty (60) days after filing; or

                        (vi) If a decree or order is entered for the appointment
        of a trustee, receiver or liquidator for HFC or the property of HFC;
        provided, however, that the Default arising in consequence thereof shall
        be cured if such decree or order is vacated within sixty (60) days after
        the date of entry; or

                        (vii) If HFC commences any proceeding for dissolution or
        liquidation; or any such proceeding is commenced against HFC and the
        proceeding is not dismissed within ninety (90) days after the date of
        commencement; or

                        (viii) If HFC makes an assignment for the benefit of his
        creditors, or admits in writing his inability to pay his debts generally
        as they become due; or

                        (ix) If there is an attachment, execution or other
        judicial seizure of any property of HFC; provided, however, that the
        Default arising in consequence thereof shall be cured if such seizure is
        discharged within ten (10) days; or

                        (x) If a judgment or other claim becomes a lien or
        encumbrance upon any material portion of HFC's properties or assets; or

                        (xi) If any representation or disclosure made in writing
        to M-F Downtown by HFC in connection with the Transaction proves to be
        materially false or misleading when made; or

                        (xii) If there is a default in any material agreement to
        which HFC is a party with one or more third Persons resulting in a right
        by such third Persons, irrespective of whether exercised, to accelerate
        the maturity of HFC's obligations thereunder; or

                        (xiii) Except with respect to (i) the payment of money
        and (ii) the other matters hereinbefore and hereinafter specified in
        this Section 5(a), if HFC shall default in


                                      -10-
<PAGE>
        the observance or performance of any covenant or agreement contained in
        this Assignment Agreement for thirty (30) days after the giving by M-F
        Downtown to HFC of written notice thereof (or, with respect to a default
        which, in the judgment of M-F Downtown, shall be of such a nature that
        it cannot be cured or remedied within thirty (30) day period, if HFC
        shall not (x) promptly commence to cure within such thirty (30) day
        period and thereafter exercise due diligence and continuous good faith
        effort to remedy the same or (y) cure such failure within sixty (60)
        days after the giving by M-F Downtown to HFC of written notice thereof),
        or failure for such lesser time period as may be specified elsewhere in
        this Assignment Agreement.

                (b) REMEDIES GENERALLY. Following the occurrence and during the
continuation of an Event of Default, M-F Downtown may, in addition to all other
rights and remedies granted to it herein, exercise all the rights and remedies
of a secured party under the Code and, in addition, M-F Downtown may, without
being required to give any notice, except as hereinafter provided or as may be
required by mandatory provisions of law, continue to apply any cash payments
then held by it, and/or sell the Collateral, or any part thereof, at public or
private sale or at any broker's board or on any securities exchange, for cash,
upon credit or for future delivery, and at such price or prices as M-F Downtown
may deem satisfactory. M-F Downtown may be the purchaser of any or all of the
Collateral so sold at any public sale (or, if the Collateral is of a type
customarily sold in a recognized market or is of a type which is the subject of
widely distributed standard price quotations, at any private sale) and
thereafter hold the same, absolutely, free from any right or claim of HFC
whatsoever. To the fullest extent permitted by law, HFC hereby specifically
waives all rights of stay or appraisal which it has or may have under any rule
of law or statute now existing or hereafter in force. M-F Downtown shall give
HFC at least five (5) days prior written notice of its intention to make any
such public or private sale or sale at a broker's board or on a securities
exchange. Such notice, in case of a public sale, shall state the time and place
fixed for such sale, and, in case of sale at a broker's board or on a securities
exchange, shall state the board or exchange at which such sale is to be made and
the day on or after which the Collateral or the portion thereof so being sold
will first be offered for sale at such board or exchange. Any such public sale
shall be held at such time or times within ordinary business hours and at such
place or places as M-F Downtown may fix in the notice of such sale. At any such
sale the Collateral may be sold in one lot as an entirety or in separate
parcels, as M-F Downtown may determine. M-F Downtown shall not be obligated to
make any such sale pursuant to any such notice. M-F Downtown may, without notice
or publication, adjourn any public or private sale or cause the same to be
adjourned from time to time by announcement at the time and place fixed for the
sale, and such sale may be made at any time or place to which the same may be so
adjourned. In case of any sale of all or any part of the Collateral on credit or
for future delivery, the Collateral so sold may be retained by M-F Downtown
until the selling price is paid by the purchaser thereof, but M-F Downtown shall
not incur any liability in case of the failure of such purchaser to take up and
pay for the Collateral so sold and, in case of any such failure, such Collateral
may again be sold upon like notice. M-F Downtown, instead of exercising the
power of sale herein conferred upon it, may proceed by a suit or suits at law or
in equity to foreclose the security interests herein granted and sell the
Collateral, or any portion thereof, under a judgment or decree of a court or
courts of competent jurisdiction.

                (c) APPLICATION OF MONEYS. The proceeds of any sale, disposition
or other realization upon all or any part of the Collateral (other than a
retention of all or part of the Collateral in full satisfaction of the
Obligations) shall be distributed by M-F Downtown in the following order of
priority, to the fullest extent permitted by law, as soon as practicable:

                        First: To M-F Downtown for any unpaid fees and other
                amounts payable to M-F Downtown pursuant to Section 5(d) hereof;

                        Second: To M-F Downtown in an amount equal to the
                aggregate amount of Obligations which are then unpaid; and

                        Third: Any surplus then remaining shall be distributed
                without recourse or warranty, to HFC.

                (d) COMPENSATION AND EXPENSES. HFC shall pay to M-F Downtown,
from time to time upon demand (i) all reasonable fees and out-of-pocket expenses
of counsel for M-F Downtown, in connection with the enforcement of this
Assignment Agreement and Other Assurances or the Collateral, and (ii) all other
out-of-pocket costs and expenses of M-F Downtown in connection with the
enforcement of this Assignment Agreement and each Other Assurance, including,
without limitation, any advance made by M-F Downtown on behalf of HFC under any
Other Assurance, the sale or other disposition of Collateral pursuant to any
Other Assurance and the preservation, protection or defense of M-F Downtown's
rights under this Assignment Agreement and any Other Assurance and in and to the
Collateral.

        6. MISCELLANEOUS

                (a) NATURE OF RELATIONSHIP. M-F Downtown and HFC intend that the
relationship between them shall be solely that of creditor and debtor. Nothing
in this Assignment Agreement or the Obligation Documents shall be construed to
create a partnership or any other relationship which would make M-F Downtown in
any way responsible or liable for the debts, losses, obligations or duties of
HFC. In that regard, HFC acknowledges and agrees that:

                        (i) M-F Downtown shall not be directly or indirectly
        liable or responsible for any loss or injury of any kind to any Person

        agents, independent contractors, licensees or invitees;

                        (ii) M-F Downtown shall not be responsible or liable to
        HFC for the validity, sufficiency or genuineness of any documents
        (except as to M-F Downtown's signatures thereon), or of any endorsements
        thereon, even if such documents should in fact prove to be in any
        respect invalid, insufficient, inaccurate, fraudulent or forged.

                (b) NOTICES. Any notice or other communication hereunder shall
be in writing and shall be given personally, or by prepaid registered mail with
return receipt requested or by commercial airfreight delivery service
guaranteeing next day delivery. Notices may also effectively be given by
transmittal over electronic transmitting devices such as facsimile, telex or
telecopy machine if the party to whom the notice is being sent has such a device

transmitted shall also be mailed in the same manner as required for a mailed

Except as otherwise expressly provided under the terms and conditions of this

the parties hereto and their respective heirs, devisees, legatees,

generality of the foregoing, HFC acknowledges and agrees that the rights of M-F

of Santa Clara and State of California, and (b) waives any objection which it
may have at any time to the laying of venue of any proceeding brought in any
such court, waives any claim that any proceeding has been brought in an
inconvenient forum and further waives the right to object, with respect to such
proceeding, that such court does not have jurisdiction over such party. Nothing
in this Assignment Agreement shall preclude M-F downtown from bringing a
proceeding in any other jurisdiction nor will the bringing of a proceeding in
any one or more jurisdictions preclude the bringing of a proceeding in any other
jurisdiction.

        8. WAIVER OF JURY TRIAL. HFC AND M-F DOWNTOWN EACH, TO THE MAXIMUM

THIS ASSIGNMENT AGREEMENT CONSTITUTES A WRITTEN CONSENT TO WAIVER OF TRIAL BY
JURY PURSUANT TO THE PROVISIONS OF SECTION 631 OF THE CALIFORNIA CODE OF CIVIL
PROCEDURE. HFC AND M-F DOWNTOWN HEREBY AGREE THAT THIS ASSIGNMENT AGREEMENT
CONSTITUTES A WRITTEN CONSENT TO WAIVER OF TRIAL BY JURY PURSUANT TO THE
PROVISIONS OF CALIFORNIA CODE OF CIVIL PROCEDURE SECTION 631. HFC DOES HEREBY
CONSTITUTE AND APPOINT M-F DOWNTOWN ITS TRUE AND LAWFUL ATTORNEY-IN-FACT, WHICH
APPOINTMENT IS COUPLED WITH AN INTEREST, AND HFC DOES HEREBY AUTHORIZE AND
EMPOWER M-F DOWNTOWN, IN THE NAME, PLACE AND STEAD OF HFC, TO FILE THIS
