8. PAYMENT OF PREMIUMS, TAXES, CHARGES, LIENS AND ASSESSMENTS. Debtor agrees to
pay, prior to delinquency, all insurance premiums, taxes, charges, liens and
assessments against the Collateral and Proceeds, and upon the failure of Debtor
to do so, Bank at its option may pay any of them and shall be the sole judge of
the legality or validity thereof and the amount necessary to discharge the same.
Any such payments made by Bank shall be obligations of Debtor to Bank, due and
payable immediately upon demand, together with interest at a rate determined in
accordance with the provisions of this Agreement, and shall be secured by the
Collateral and Proceeds, subject to all terms and conditions of this Agreement.

9. EVENTS OF DEFAULT. The occurrence of any of the following shall constitute an
"Event of Default" under this Agreement: (a) any default in the payment or
performance of any obligation, or any defined event of default, under (i) any
contract or instrument evidencing any Indebtedness, or (ii) any other agreement
between Debtor and Bank, including without limitation any loan agreement,
relating to or executed in connection with any Indebtedness; (b) any
representation or warranty made by Debtor herein shall prove to be incorrect,
false or misleading in any material respect when made; (c) Debtor shall fail to
observe or perform any obligation or agreement contained herein; (d) any
impairment of the rights of Bank in any Collateral or Proceeds or any attachment
or like levy on any property of Debtor; and (e) Bank, in good faith, believes
any or all of the Collateral and/or Proceeds to be in danger of misuse,
dissipation, commingling, loss, theft, damage or destruction, or otherwise in
jeopardy or unsatisfactory in character or value.

10. REMEDIES. Upon the occurrence of any Event of Default, Bank shall have the
right to declare immediately due and payable all or any Indebtedness secured
hereby and to terminate any commitments to make loans or otherwise extend credit
to Debtor. Bank shall have all other rights, powers, privileges and remedies
granted to a secured party upon default under the California Uniform Commercial
Code or otherwise provided by law, including without limitation, the right (a)
to contact all persons obligated to Debtor on any Collateral or Proceeds and to
instruct such persons to deliver all Collateral and/or Proceeds directly to
Bank, and (b) to sell, lease, license or otherwise dispose of any or all
Collateral. All rights, powers, privileges and remedies of Bank shall be
cumulative. No delay, failure or discontinuance of Bank in exercising any right,
power, privilege or remedy hereunder shall affect or operate as a waiver of such
right, power, privilege or remedy; nor shall any single or partial exercise of
any such right, power, privilege or remedy preclude, waive or otherwise affect
any other or further exercise thereof or the exercise of any other right, power,
privilege or remedy. Any waiver, permit, consent or approval of any kind by Bank
of any default hereunder, or any such waiver of any provisions or conditions
hereof, must be in writing and shall be effective only to the extent set forth
in writing. It is agreed that public or private sales or other dispositions, for
cash or on credit, to a wholesaler or retailer or investor, or user of property
of the types subject to this Agreement, or public auctions, are all commercially
reasonable since differences in the prices generally realized in the different
kinds of dispositions are ordinarily offset by the differences in the costs and
credit risks of such dispositions.

While an Event of Default exists: (a) Debtor will deliver to Bank from time to
time, as requested by Bank, current lists of all Collateral and Proceeds; (b)
Debtor will not dispose of any Collateral or Proceeds except on terms approved
by Bank; (c) at Bank's request, Debtor will assemble and deliver all Collateral
and Proceeds, and books and records pertaining thereto, to Bank at a reasonably
convenient place designated by Bank; and (d) Bank may, without notice to Debtor,
enter onto Debtor's premises and take possession of the Collateral. Debtor
further agrees that Bank shall have no obligation to process or prepare any
Collateral for sale or other disposition.

11. DISPOSITION OF COLLATERAL AND PROCEEDS; TRANSFER OF INDEBTEDNESS. In
disposing of Collateral hereunder, Bank may disclaim all warranties of title,
possession, quiet enjoyment and the like. Any proceeds of any disposition of any
Collateral or Proceeds, or any part thereof, may be applied by Bank to the
payment of expenses incurred by Bank in connection with the foregoing, including
reasonable attorneys' fees, and the balance of such proceeds may be applied by
Bank toward the payment of the Indebtedness in such order of application as Bank
may from time to time elect. Upon the transfer of all or any part of the
Indebtedness, Bank may transfer all or any part of the Collateral or Proceeds
and shall be fully discharged thereafter from all liability and responsibility
with respect to any of the foregoing so transferred, and the transferee shall be
vested with all rights and powers of Bank hereunder with respect to any of the
foregoing so transferred; but with respect to any Collateral or Proceeds not so
transferred Bank shall retain all rights, powers, privileges and remedies herein
given.

12. STATUTE OF LIMITATIONS. Until all Indebtedness shall have been paid in full
and all commitments by Bank to extend credit to Debtor have been terminated, the
power of sale or other disposition and all other rights, powers, privileges and
remedies granted to Bank hereunder shall continue to exist and may be exercised
by Bank at any time and from time to time irrespective of the fact that the
Indebtedness or any part thereof may have become barred by any statute of
limitations, or that the personal liability of Debtor may have ceased, unless
such liability shall have ceased due to the payment in full of all Indebtedness
secured hereunder.

13. MISCELLANEOUS. When there is more than one Debtor named herein: (a) the word
"Debtor" shall mean all or any one or more of them as the context requires; (b)
the obligations of each Debtor hereunder are joint and several; and (c) until
all Indebtedness shall have been paid in full, no Debtor shall have any right of
subrogation or contribution, and each Debtor hereby waives any benefit of or
right to participate in any of the Collateral or Proceeds or any other security
now or hereafter held by Bank. Debtor hereby waives any right to require Bank to
(i) proceed against Debtor or any other person, (ii) proceed against or exhaust
any security from Debtor or any other person, (iii) perform any obligation of
Debtor with respect to any Collateral or Proceeds, and (d) make any presentment
or demand, or give any notice of nonpayment or nonperformance, protest, notice
of protest or notice of dishonor hereunder or in connection with any Collateral
or Proceeds. Debtor further waives any right to direct the application of
payments or security for any Indebtedness of Debtor or indebtedness of customers
of Debtor.

14. NOTICES. All notices, requests and demands required under this Agreement
must be in writing, addressed to Bank at the address specified in any other loan
documents entered into between Debtor and Bank and to Debtor at the address of
its chief executive office (or principal residence, if applicable) specified
below or to such other address as any party may designate by written notice to

the date of receipt or 3 days after deposit in the U. S. mail, first class and
postage prepaid; and (c) if sent by telecopy, upon receipt.

15. COSTS, EXPENSES AND ATTORNEYS' FEES. Debtor shall pay to Bank immediately
upon demand the full amount of all payments, advances, charges, costs and
expenses, including reasonable attorneys' fees (to include outside counsel fees
and all allocated costs of Bank's in-house counsel), expended or incurred by
Bank in exercising any right, power, privilege or remedy conferred by this

Agreement or in the enforcement thereof, whether incurred at the trial or
appellate level, in an arbitration proceeding or otherwise, and including any of
the foregoing incurred in connection with any bankruptcy proceeding (including
without limitation, any adversary proceeding, contested matter or motion brought
by Bank or any other person) relating to Debtor or in any way affecting any of
the Collateral or Bank's ability to exercise any of its rights or remedies with
respect thereto. All of the foregoing shall be paid by Debtor with interest from
the date of demand until paid in full at a rate per annum equal to the greater
of ten percent (10%) or Bank's Prime Rate in effect from time to time.

16. SUCCESSORS; ASSIGNS; AMENDMENT. This Agreement shall be binding upon and
inure to the benefit of the heirs, executors, administrators, legal
representatives, successors and assigns of the parties, and may be amended or

Collateral and Proceeds under this Agreement.

18. SEVERABILITY OF PROVISIONS. If any provision of this Agreement shall be held
to be prohibited by or invalid under applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without
