       addition to the foregoing expenses, the Company agrees to pay the
       following reasonable expenses, in compliance with its standard policies,
       until the earlier of (i) your permanent move from Seattle, Washington to
       the San Francisco/Bay Area in California or (ii) five (5) months from the
       Vesting Commencement Date (the "Reimbursement Period"):

            .    Weekly round-trip, economy class airline tickets between San
                 Francisco, CA and Seattle, WA;

            .    Two round-trip, economy class airline tickets between Seattle,
                 WA and San Francisco, CA for your spouse for the purpose of
                 searching for housing in the San Francisco/Bay Area;

            .    Temporary housing expenses, which may be reflected by either a
                 temporary apartment arrangement or hotel expenses during the
                 Reimbursement Period; and

            .    Car rental payments, including applicable insurance, during the
                 Reimbursement Period.

       If any of these allowances or expenses are deemed taxable to you for
       Federal or State Income Tax purposes, then the Company will provide you
       with additional compensation to cover any tax liability owed, so that the
       effect of such

5
<PAGE>

[LOGO]   allowances or expenses is tax neutral to you. The additional
         compensation will be provided should there be additional tax liability
         to you.

10.      Insurance

         The Company shall, to the extent permitted by law, include you, so long
         as you are still employed by the Company, under any directors and
         officers' liability insurance policy maintained by the Company for its
         directors and officers. The coverage shall be at least as favorable to
         you in amount and each other material respect as the coverage of other
         directors and officers covered thereby. This obligation to provide
         insurance shall survive expiration or termination of this Agreement
         with respect to proceedings or threatened proceedings based on acts or
         omissions occurring during your employment with the Company or with any
         affiliated company. Please be advised that during your employment with
         the Company you will be deemed a Section 16 officer and will be subject
         to the applicable rules and regulations.

11.      Housing Allowance and Car Assistance

         The Company has determined that, for the first four (4) months
         following the Reimbursement Period (the "Initial Housing Allowance
         Period"), you shall be entitled to receive, while residing in the San
         Francisco/Bay Area, a maximum monthly housing allowance in the amount
         of $6,500 per month, net of taxes (the "Initial Housing Allowance");
         i.e., the Company will provide you with additional compensation to
         cover the incremental Federal and State Taxes that accrue to you as a
         result of this housing allowance so that its effect is tax neutral to
         you. Immediately following the Initial Housing Allowance Period, for
         the next eight (8) months (the "Subsequent Housing Allowance Period,"
         which, together with the Initial Housing Allowance Period, the
         "Allowance Period") you shall be entitled to receive, while residing in
         the San Francisco/Bay Area, a maximum monthly housing allowance in the
         amount of $4,000 per month, net of taxes (the "Subsequent Housing
         Allowance," which, together with the Initial Housing Allowance, the
         "Housing Allowance"). The Company acknowledges, and you agree, that the
         intent of the Housing Allowance is to ensure that you are in no worse
         or better position financially, with respect to housing, than you would
         be absent your relocation and decision to join the Company. In light of
         the foregoing, the Housing Allowance will be adjusted downward, net of
         taxes, if the difference between your current mortgage and your monthly
         housing cost after relocation (the "Housing Differential") is less than
         $4,000. If the Housing Differential is less than $4,000, then the
         Housing Allowance will equal the Housing Differential plus $2,500 (net
         of taxes) during the Initial Housing Allowance Period and will equal
         the Housing Differential in the Subsequent Housing Allowance Period.
         For illustration purposes, if your current mortgage is $3,000 and your
         monthly rent after relocation is $6,000 for comparable housing, then
         your Housing Allowance will equal $5,500, net of taxes, in the Initial
         Housing
6
<PAGE>

        Allowance Period and will equal $3,000 in the Subsequent Housing
        Allowance Period.

[LOGO]  For clarification purposes, it is understood and agreed that after the
        Allowance Period, you shall no longer be entitled to receive a housing
        allowance from the Company. If you are terminated Without Cause at any
        point during the Allowance Period, the Company agrees to pay you for
        your actual housing expenses, which payments shall not exceed $4,000 per
        month, net of taxes, and shall be supported by documentation provided by
        you to the Company, from the date of such termination until the end of
        the Allowance Period. Notwithstanding the foregoing, the Company shall
        also grant you a housing deposit allowance (the "Housing Deposit
        Allowance"), of up to $10,000, which shall be utilized solely for the
        purpose of providing your landlord a housing deposit pursuant to the
        terms of your lease agreement. Please be advised that typically under
        California Law, a lease deposit may not exceed two (2) months rent. You
        shall provide the Company with appropriate documentation evidencing the
        amount of such Housing Deposit Allowance. Upon the earlier of (i) the
        end of the term of your lease; or (ii) one (1) year following the
        Allowance Period, you shall remit back to the Company the full amount of
        the Housing Deposit Allowance. The provisions of this paragraph 11 shall
        not be applicable if, subsequent to the Reimbursement Period, you and
        your family have not permanently relocated to the San Francisco/Bay
        Area, however, each of you and the Company agree that if such a
        situation were to arise, both parties will negotiate in good faith to
        reach an alternative arrangement with respect to relocation and housing
        allowances.

12.     Relocation

        To facilitate your relocation, you will be entitled to receive a
        reimbursement of up to $30,000 for the actual costs associated with your
        move, including the following:

        .    All reasonable costs incurred in relation to Employee's move to the
             San Francisco/Bay Area in California, whether incurred before or
             after the date of this Agreement;

        .    Removal and Relocation of Households Goods; and

        .    Travel to Relocate (including, but not limited to, one-way economy
             class tickets for the purpose of relocation for the number of
             family members involved or, if you decide to relocate via ground
             transportation, gas mileage and all reasonable lodging and food
             expenses incurred during the trip).

        If any part of the reimbursement is deemed taxable to you for Federal or
        State Income Tax purposes, then the Company will provide you with
        additional compensation to cover any tax liability owed, so that the
        effect of such reimbursement is tax neutral to you. The additional
        compensation will be provided should there be additional tax liability
        to you.

7
<PAGE>

[LOGO]   You must retain for your records, and for documentation to be provided
         to the Company in connection with the reimbursement of these relocation
         expenses, all receipts related to your move. In addition to the
         foregoing, the Company also agrees to pay any fees incurred during the
         Allowance Period directly associated with your transfer and/or
         registration of any automobiles in the State of California.

13.      Proprietary and Confidential Information Your acceptance of this offer
         is contingent upon the execution of the Company's Proprietary
         Inventions and Information Agreement ("PIIA"), a copy of which is
         attached hereto as Exhibit A. Within five days of the commencement of
         your employment, you will execute the Company's standard form of PIIA,
