Except as otherwise expressly permitted herein, in the event Debtor receives any such Proceeds, Debtor will hold the same in trust on behalf of and for the benefit of Bank and will immediately deliver all such Proceeds to Bank in the exact form received, with the endorsement of Debtor if necessary and/or appropriate undated stock powers duly executed in blank, to be held by Bank as part of the Collateral, subject to all terms hereof. As used herein, the terms "security entitlement," "financial asset" and "investment property" shall have the respective meanings set forth in the California Uniform Commerical Code.

        2.    OBLIGATIONS SECURED.    The obligations secured hereby are the payment and performance of: (a) all present and future Indebtedness of Debtor to Bank; (b) all obligations of Debtor and rights of Bank under this Agreement; and (c) all present and future obligations of Debtor to Bank of other kinds. The word "Indebtedness" is used herein in its most comprehensive sense and includes any and all advances, debts, obligations and liabilities of Debtor, or any of them, heretofore, now or hereafter made, incurred or created, whether voluntary or involuntary and however arising, whether due or not due, absolute or contingent, liquidated or unliquidated, determined or undetermined, including under any swap, derivative, foreign exchange, hedge, deposit, treasury management or other similar transaction or arrangement, and whether Debtor may be liable individually or jointly, or whether recovery upon such Indebtedness may be or hereafter becomes unenforceable.

        3.    TERMINATION.    This Agreement will terminate upon the performance of all obligations of Debtor to Bank, including without limitation, the payment of all Indebtedness of Debtor to Bank, and the termination of all commitments of Bank to extend credit to Debtor, existing at the time Bank receives written notice from Debtor of the termination of this Agreement.

        4.    OBLIGATIONS OF BANK.    Bank has no obligation to make any loans hereunder. Any money received by Bank in respect of the Collateral may be deposited, at Bank's option, into a non-interest bearing account over which Debtor shall have no control, and the same shall, for all

1

purposes, be deemed Collateral hereunder. Bank shall have no duty to take any steps necessary to preserve the rights of Debtor against prior parties, or to initiate any action to protect against the possibility of a decline in the market value of the Collateral or Proceeds. Bank shall not be obligated to take any action with respect to the Collateral or Proceeds requested by Debtor unless such request is made in writing and Bank determines, in its sole discretion, that the requested action would not unreasonably jeopardize the value of the Collateral and Proceeds as security for the Indebtedness.

        5.2   Intermediary shall send copies of all statements relating to the Securities Account simultaneously to Customer and Secured Party.

        5.3   Intermediary shall promptly notify Secured Party if any other party asserts any claim to, security interest in or lien upon any of the Collateral, and Intermediary shall not enter into any control, custodial or other similar agreement with any other party that would create or acknowledge the existence of any such other claim, security interest or lien.

        5.4   Without Secured Party's prior written consent, Intermediary and Customer shall not amend or modify the Account Agreement, other than: (a) amendments to reflect ordinary and reasonable changes in Intermediary's fees and charges for handling the Securities Account; and (b) operational changes initiated by Intermediary as long as they do not alter any of Secured Party's rights hereunder.

        5.5   Neither Intermediary nor Customer shall terminate the Account Agreement without giving 30 days' prior written notice to Secured Party.
