                      not pay), except as provided in Section 2, above, any part
                      of the Subordinated Debt, by payment, prepayment, or
                      otherwise,

               (b)    exercise any remedy against the Collateral, or

               (c)    accelerate the Subordinated Debt, or begin to or
                      participate in any action against the Borrower, until all
                      the Senior Debt is paid.

        4. The Creditors must deliver to the Investors in the form received

distribution, security or proceeds it receives on the Subordinated Debt other

Borrower's insolvency, reorganization or any case or proceeding under any
bankruptcy or insolvency law, and the Investors' claims against the Borrower and
the Borrower's estate will be fully paid, to the extent arising from sums
subordinated hereunder, before any payment is made to the Creditors.

        6. Until the Senior Debt is paid, the Creditors irrevocably appoint the
Investors as their attorney-in-fact, with power of attorney with power of
substitution, in the Creditors' names or in Investors' name, for the Investors'
use and benefit, with 5 business days notice to the Creditors, to do the
following in any bankruptcy, insolvency or similar proceeding involving the
Borrower:

               (a)    File any claims for the Subordinated Debt for the
                      Creditors if the Creditors do not do so at least 30 days
                      before the time to file claims expires, and

               (b)    Accept or reject any plan of reorganization or arrangement
                      for the Creditors and vote the Creditors' claims in
                      respect of the Subordinated Debt in any way it chooses.

        7. The Creditors will immediately put a legend on the Subordinated Debt
instruments that the instruments are subject to this Agreement. No amendment of
the Subordinated Debt documents will modify this Agreement in any way that
terminates or impairs the subordination of the Subordinated Debt or the
subordination of the security interest or lien that the Investors have in
Borrower's property. For example, instruments may not be amended to (i) increase
the interest rate of the Subordinated Debt, or (ii) accelerate payment of
principal or interest or any other portion of the Subordinated Debt.

        8. This Agreement shall remain in full force and effect so long as the
Borrower owes any portion of the Senior Debt to the Investors. If, after full
payment of the Senior Debt, the investors must disgorge any payments made on the
Senior Debt, this Agreement and the relative rights and priorities provided in
it, will be reinstated as to all disgorged payments as though the payments had
not been made, and the Creditors will immediately pay the Investors all payments
received under the Subordinated Debt to the extent the payments would have been
prohibited under this Agreement. At any time without notice to the Creditors,
the Investors may take actions it considers appropriate on the Senior Debt such
as terminating advances, increasing the principal,

extending the time of payment, increasing interest rates, renewing, compromising
or otherwise amending any documents affecting the Senior Debt and any collateral
securing the Senior Debt, and enforcing or failing to enforce any rights against
the Borrower or any other person. No action or inaction will impair or otherwise
affect the Investors' rights under this Agreement. The Creditors waive any
benefits of California Civil Code Sections 2809,2810, 2819, 2845, 2847, 2848,
2849, 2850, 2899 and 3433.

        9. This Agreement binds the Creditors, their successors or assigns, and
benefits Investors' successors or assigns. This Agreement is for the Investors'
benefit and not for the benefit of the Borrower or any other party. If the
Borrower is refinancing any of the Senior Debt with a new lender, upon the
Investors' request of Creditors, the Creditors will enter into a new
subordination agreement with the new lender on substantially the terms of this
Agreement.

        10. This Agreement may be executed in two or more counterparts, each of
which is an original and all of which together constitute one instrument.

        11. California law governs this agreement without giving effect to
conflicts of law principles. The Creditors and the Investors submit to the
exclusive jurisdiction of the courts in Santa Clara County, California. THE
CREDITORS AND THE INVESTORS EACH WAIVE THEIR RIGHTS TO A JURY TRIAL OF ANY CLAIM

this Agreement. The Creditors will keep themselves informed of the Borrower's
financial and other conditions. This Agreement may be amended only by written
instrument signed by the Creditors and Investors.

        13. If there is an action to enforce the rights of a party under this
Agreement, the party prevailing will be entitled, in addition to other relief,
