of collecting the Debt, of protecting, insuring or realizing on Collateral, and
any expenditure of Bank pursuant hereto, including attorneys' fees and expenses,
with interest at the rate of 24% per year, or the rate applicable to the Debt,
whichever is less, from the date of expenditure, and (c) any deficiency after
realization of Collateral.

     2. Obligor will use the proceeds of any loan that becomes Debt hereunder
for the purpose indicated on the application therefore, and will promptly
contract to purchase and pay the purchase price of any property which becomes
Collateral hereunder from the proceeds of any loan made for that purpose.

     3. As to all Collateral in Obligor's possession (unless specifically
otherwise agreed to by Bank in writing), Obligor will:

     (a) Have, or has, possession of the Collateral at the location disclosed to
         Bank and will not remove the Collateral from the location.

     (b) Keep the Collateral separate and identifiable.

     (c) Maintain the Collateral in good and saleable condition, repair if
     necessary, clean, feed, shelter, water, medicate, fertilize, cultivate,
     irrigate, prune and otherwise deal with the Collateral in all such ways as
     are considered good practice by owners of like property, use it lawfully
     and only as permitted by insurance policies, and permit Bank to inspect the
     Collateral at any reasonable time.

     (d) Not sell, contract to sell, lease encumber or transfer the Collateral
     (other than Inventory Collateral) until the Debt has been paid, even though
     Bank has a security interest in proceeds of such Collateral.

     4. As to Collateral which is inventory and accounts, Obligor:

     (a) May, until notice from Bank, sell, lease or otherwise dispose of
     Inventory Collateral in the ordinary course of business only, and collect
     the cash proceeds thereof.

     (b) Will, upon notice from Bank, deposit all cash proceeds as received in
     a demand deposit account with Bank, containing only such proceeds and
     deliver statements identifying units of inventory disposed of, accounts
     which gave rise to proceeds, and all acquisitions and returns of inventory
     as required by Bank.

     (c) Will receive in trust, schedule on forms satisfactory to the Bank and
     deliver to Bank all non-cash proceeds other than inventory received in
     trade.

     (d) If not in default, may obtain release of Bank's interest in individual
     units of inventory upon request, therefore, payment to Bank of the release
     price of such units shown on any collateral schedule supplementary hereto,
     and compliance herewith as to proceeds thereof.

     5. As to Collateral which are accounts, chattel paper, general intangibles
and proceeds described in 4(c) above, Obligor warrants, represents and agrees:

     (a) All such Collateral is genuine, enforceable in accordance with its
     terms, free from default, prepayment, defense and conditions precedent
     (except as disclosed to and accepted by Bank in writing), and is supported
     by consecutively numbered invoices to, or rights against, the debtor
     thereon. Obligor will supply Bank with duplicate invoices or other evidence
     of Obligor's rights on Bank's request;

     (b) All persons appearing to be obligated on such Collateral have authority
     and capacity to contract;

     (c) All chattel paper is in compliance with law as to form, content and

     recorded, and/or filed to protect Obligor's interest thereunder;

     (d) If an account debtor shall also be indebted to Obligor on another
     obligation, any payment made by him not specifically designated to be
     applied on any particular obligation shall be considered to be a payment on
     the account in which Bank has a security interest. Should any remittance
     include a payment not on an account, it shall be delivered to Bank and, if
     no event of default has occurred, Bank shall pay Obligor the amount of such
     payment;

     (e) Obligor agrees not to compromise, settle or adjust any account or renew
     or extend the time of payment thereof without Bank's prior written consent.

     6. Obligor owns all Collateral absolutely, and no other person has or
claims any interest in any Collateral, except as disclosed to and accepted by
Bank in writing. Obligor will defend any proceeding which may affect title to or
Bank's security interest in any Collateral, and will indemnify and hold Bank
free and harmless from all costs and expense of Bank's defense.

     7. Obligor will pay when due all existing or future charges, liens or
encumbrances on and all taxes and assessments now or hereafter imposed on or
affecting the Collateral and, if the Collateral is in Obligor's possession, the
realty on which the Collateral is located.

     8. Obligor will insure the Collateral with Bank as loss payee in form and
amounts with companies, and against risks and liability satisfactory to Bank,
and hereby assigns such policies to Bank, agrees to deliver them to Bank at
Bank's request, and authorizes Bank to make any claim thereunder, to cancel the
insurance on Obligor's default, and to receive payment of and endorse any
instrument in payment of any loss or return premium. If Obligor should fail to
deliver the required policy or policies to the Bank, Bank may, at Obligor's cost
and expense, without any duty to do so, get and pay for insurance naming at the
insured, at Bank's option, either both Obligor and Bank, or only Bank, and the
cost thereof shall be secured by this Security Agreement, and shall be repayable
as provided in Paragraph 1 above.

     9. Obligor will give Bank any information it requires. All information at
any time supplied to Bank by Obligor (including, but not limited to, the value
and condition of Collateral, financial statements, financing statements, and
statements made in documentary Collateral) is correct and complete, and Obligor
will notify Bank of any adverse change in such information. Obligor will
promptly notify Bank of any change of Obligor's residence, chief executive
office or mailing address.

     10. Bank is irrevocably appointed Obligor's attorney-in-fact to do any act
which Obligor is obligated hereby to do, to exercise such rights as Obligor may
exercise, to use such equipment as Obligor might use, to enter Obligor's
premises to give notice of Bank's security interest, and to collect Collateral
and proceeds and to execute and file in Obligor's name any financing statements
and amendments thereto required to perfect Bank's security interest hereunder,
all to protect and preserve the Collateral and Bank's rights hereunder. Bank
may:

     (a) Endorse, collect and receive delivery or payment of instruments and
     documents constituting Collateral:

     (b) Make extension agreements with respect to or affecting Collateral,
     exchange it for either Collateral, release persons liable thereon or take
     security for the payment thereof, and compromise disputes in connection
     therewith;

     (c) Use or operate Collateral for the purpose of preserving Collateral or
     its value and for preserving or liquidating Collateral.

     11. If more than one Obligor signs this Agreement, their liability is joint
and several. Any Obligor who is married agrees that recourse may be had against
separate property for the Debt. Discharge of any Obligor except for full
payment, or any extension, forbearance, change of rate of interest, or
acceptance, release or substitution of Collateral or any impairment or
suspension of Bank's rights against an Obligor, or any transfer of an Obligor's
interest to another shall not affect the liability of any other Obligor. Until
the Debt shall have been paid or performed in full, Bank's rights shall
continue even if the Debt is outlawed. All Obligors waive; (a) any right to
require Bank to proceed against any Obligor before any other, or to pursue any
other remedy; (b) presentment, protest and notice of protest, demand and notice
of nonpayment, demand or performance, notice of safe, and advertisement of sale;
(c) any right to the benefit of or to direct the application of any Collateral
until the Debt shall have been paid; (d) and any right of subrogation to Bank

     12. Upon default, at Bank's option, without demand or notice, all or any
part of the Debt shall immediately become due. Bank shall have all rights given
by law, and may sell, in one or more sales, Collateral in any country where Bank
has an office. Bank may purchase at such sale. Sales for cash or on credit to
wholesale, retailer or user of the Collateral, or at public or private auction,
are all to be considered commercially reasonable. Bank may require Obligor to
assemble the Collateral and make it available to Bank at the enhance to the
location of the Collateral, or a place designated by Bank.

     Defaults shall include:

     (a) Obligor's failure to pay or perform this or any agreement with Bank or
     breach of any warranty herein, or Borrower's failure to pay or perform any
     agreement with Bank.

     (b) Any change in Obligor's or borrower's financial condition which in
     Bank's judgment impairs the prospect of Borrower's payment or performance.

     (c) Any actual or reasonably anticipated deterioration of the Collateral or
     in the market price thereof which causes it. In Bank's judgment, to become
     unsatisfactory as security.

     (d) Any levy or seizure against Borrower or any of the Collateral.

     (e) Death, termination of business, assignment for creditors, insolvency,
     appointment of receiver, or the filing of any petition under bankruptcy or
     debtor's relief laws of, by or against Obligor or Borrower or any guarantor
     of the Debt.

     (f) Any warranty or representation which is false or is believed in good
     faith by Bank to be false.

     13. Bank's acceptance of partial or delinquent payments or the failure of
bank to exercise any right or remedy shall not waive any obligation of Obligor
or Borrower or right of Bank to modify this Agreement, or waive any other
similar default.

     14. On transfer of all or any part of the Debt, Bank may transfer all or
any part of the Collateral. Bank may deliver all or any part of the Collateral
to any Obligor at any time. Any such transfer or delivery shall discharge Bank
from all liability and responsibility with respect to such Collateral
transferred or delivered. This Agreement benefits Bank's successors and assigns
and binds Obligor's heirs, legalees, personal representatives, successors and
assigns. Obligor agrees not to assert against any assignee of Bank any claim or
defense that may exist against Bank. Time is of the essence. This Agreement and
supplementary schedules hereto contain the entire security agreement between
Bank and Obligor. Obligor will execute any additional agreements, assignments or
documents reasonably required by Bank to carry this Agreement into effect.

     15. This Agreement shall be governed by and construed in accordance with
the laws of the State of California, to the jurisdiction of whose courts the
Obligor hereby agrees to submit. Obligor agrees that service of process may be
accomplished by any means authorized by California law. All words used herein in
the singular shall be considered to have been used in the plural where the
context and construction so require.

     16. To the extent that Obligor acquires any trademarks, service marks,
trade names and service names and/or the goodwill associated therewith,
copyrights, patents and/or patent applications (collectively "Intellectual
Property"), Obligor shall give prompt notice thereof to Bank and shall take any
and all actions requested from time to time by Bank to perfect Obligor's
interest in such Intellectual Property and to perfect Bank's first priority
