                            LOAN & SECURITY AGREEMENT

Obligations and shall thereafter accrue interest at the rate applicable to the
Credit under the terms of the Agreement.

        Borrower will pay Bank a fee equal to $20,000 on account of the
revolving facility, payable in six (6) quarterly payments of $3,333.34 each,
with the first payment due on the date hereof, and subsequent payments due on
the first day of each fiscal quarter thereafter.

           2.3 All principal and accrued but unpaid interest under Sections 2.1
and 2.2 shall be due and payable in full on November 20, 2000.

           2.4 Equipment Advances.

               (a) At any time from the date hereof through May 20, 2000, Bank
agrees to make advances (each an "Equipment Advance" and, collectively, the
"Equipment Advances") to Borrower in an aggregate outstanding amount not to
exceed Two Million Five Hundred Thousand Dollars ($2,500,000). Each Equipment
Advance shall not exceed one hundred percent (100%) of the invoice amount of
equipment, leasehold improvements, and software presented to Bank from time to
time, provided that Bank may exercise its right of prior consent in respect of
used equipment or leasehold improvements such consent not to be unreasonably
withheld, excluding taxes, shipping, warranty charges, freight discounts and
installation expense, provided that aggregate Equipment Advances used for
leasehold improvements and software shall not exceed Seven Hundred Fifty
Thousand Dollars ($750,000), and provided further that, except for the initial
Equipment Advance in a principal amount of up to $360,000 (which Borrower will
use to repay an obligation to Silicon Valley Bank), Equipment Advances shall
finance only Equipment purchased or acquired after February 21, 1999. Each
Equipment Advance shall be for a minimum of Fifty Thousand Dollars ($50,000),
provided that individual items of equipment may be for lesser amounts.

               (b) Interest shall accrue from the date of each Equipment Advance
at a rate equal to the Base Rate plus one half percent (0.5%), and shall be
payable monthly on the first (1st) day of each month through June 1, 2003.
During the continuance of an Event of Default, the Equipment Advances shall bear
interest at a rate of three (3) percentage points above the rate applicable
prior to such continuance. Any Equipment Advances that are outstanding on
December 1, 1999 ("First Tranche Advances") shall be payable in thirty-six (36)
equal monthly installments of principal, plus all accrued interest, beginning on
January 1, 2000, and continuing on the same day of each month thereafter through
December 1, 2002. Any Equipment Advances that are outstanding on June 1, 2000
and not outstanding as of December 1, 1999 (the "Second Tranche Advances") shall
be payable in thirty-six (36) equal monthly installments of principal, plus all
accrued interest, beginning on June 1, 2000, and continuing on the same day of
each month thereafter through June 1, 2003, at which time all outstanding
Equipment Advances and interest thereon shall be immediately due and payable.
Equipment Advances, once repaid, may not be reborrowed. Borrower may prepay any
Equipment Advances without penalty or premium. Notwithstanding the foregoing,
any or all First Tranche Advances or Second Tranche Advances, or both, that are
outstanding before December 1, 1999, or on June 1, 2000, may upon Borrower's
three (3) day prior written notice to Bank, accrue interest at a fixed rate
equal to three and one quarter of one percent (3.25%) above the rate quoted by
Bank to Borrower as the "Cost of Funds Rate." For the purposes of this
paragraph, "Cost of Funds Rate" shall mean the rate of interest generally
determined by Bank for purposes of all loans and credits making reference to
such "Cost of Funds," in its sole discretion, from time to time, as its cost of
funds, as such rate may change from time to time.

               (c) When Borrower desires to obtain an Equipment Advance,
Borrower shall notify Bank (which notice shall be irrevocable) by facsimile
transmission to be received no later than 5:00 p.m. Pacific Time one (1)
Business Day before the day on which the Equipment Advance is to be made. The
notice shall be signed by an officer of Borrower or its designee and (except for
the initial Equipment Advance refinancing the Silicon Valley Bank debt) include
a copy of the invoice for any equipment, leasehold improvements, and/or software
to be financed.

               (d) Borrower shall pay Bank a fee on account of the equipment
facility equal to $20,000, which shall be due and payable on the date hereof.

           2.5 Letters of Credit. Subject to the terms and conditions of this
Agreement, Bank agrees to issue or cause to be issued Letters of Credit for the
account of Borrower in an aggregate outstanding face amount not to exceed (i)
the lesser of the Borrowing Base or $4,000,000, minus (ii) the then outstanding
principal balance of the Advances; provided the face amount of such undrawn
Letters of Credit shall not at any time exceed $500,000. All Letters of Credit
shall be, in form and substance, acceptable to Bank in its sole discretion and
shall be subject to the terms and conditions of Bank's form of standard
Application and Letter of Credit Agreement. The expiry date of each Letter of
Credit shall be not later than June 1, 2000, unless Borrower secures all
obligations relating to such Letter of Credit with cash on terms reasonably
acceptable to Bank. Borrower shall pay Bank a fee as a condition to the issuance
of any Letter of Credit equal to 1.25 percent of the face amount of such Letter
of Credit.

        3. TERM.

           3.1 This Agreement shall remain in full force and effect until June
1, 2003, or until terminated by notice by Borrower. Notice of such termination
by Borrower shall be effectuated by mailing of a registered or certified letter
not less than thirty (30) days prior to the effective date of such termination,
addressed to the Bank at the address set forth herein and the termination shall
be effective as of the date so fixed in such notice. Notwithstanding the
foregoing, during the continuance of an Event of Default, Bank may terminate
this Agreement at any time without notice. Notwithstanding the foregoing, should
either Bank or Borrower become insolvent or unable to meet its debts as they
mature, or fail, suspend, or go out of business, the other party shall have the
right to terminate this Agreement at any time without notice. On the date of
termination all Obligations shall become immediately due and payable without
notice or demand; no notice of termination by Borrower shall be effective until
Borrower shall have paid all Obligations to Bank in full. Notwithstanding
termination, until all Obligations have been fully satisfied, Bank shall retain
its security interest in all existing Collateral and Collateral arising
thereafter, and Borrower shall continue to perform all of its Obligations.

           3.2 After termination and when Bank has received payment in full in
satisfaction of Borrower's Obligations to Bank, Bank shall reassign to Borrower
all Collateral held by Bank, and shall execute a termination of all security
agreements and security interests given by Borrower to Bank, upon the execution
and delivery of mutual general releases.

        4. CREATION OF SECURITY INTEREST.

           4.1 Borrower hereby grants to Bank a continuing security interest in
all presently existing and hereafter arising Collateral in order to secure
prompt repayment of any and all Obligations owed by Borrower to Bank and in
order to secure prompt performance by Borrower of each and all of its covenants
and Obligations under the Agreement and otherwise created. Bank's security
interest in the

                            LOAN & SECURITY AGREEMENT

Collateral shall attach to all Collateral without further act on the part of
Bank or Borrower. In the event that any Collateral, including proceeds, is
evidenced by or consists of Negotiable Collateral, Borrower shall, immediately
upon Bank's request, endorse and assign such Negotiable Collateral over to Bank
and deliver actual physical possession of the Negotiable Collateral to Bank.

           4.2 Bank's security interest in Receivables shall attach to all
Receivables without further act on the part of Bank or Borrower. Upon request
from Bank, Borrower shall provide Bank with schedules describing all Receivables
created or acquired by Borrower (including without limitation agings listing the
names and addresses of, and amounts owing by date by account debtors), and
during the continuance of an Event of Default shall execute and deliver written
assignments of all Receivables to Bank all in a form acceptable to Bank,
provided, however, Borrower's failure to execute and deliver such schedules
and/or assignments shall not affect or limit Bank's security interest and other
rights in and to the Receivables. Together with each schedule, Borrower shall
furnish Bank upon Bank's reasonable request with copies of Borrower's customers'
invoices or the equivalent, and original shipping or delivery receipts for all
merchandise sold, and Borrower warrants the genuineness thereof. During the
continuance of an Event of Default, Bank or Bank's designee may notify customers
or account debtors of collection costs and expenses to Borrower's account but,
unless and until Bank does so or gives Borrower other written instructions,
Borrower shall collect all Receivables for Bank, receive in trust all payments
thereon as Bank's trustee, and, if so requested to do so from Bank, Borrower
shall during the continuance of an Event of Default immediately deliver said
payments to Bank in their original form as received from the account debtor and
all letters of credit, advices of credit, instruments, documents, chattel paper
or any similar property evidencing or constituting Collateral. The receipt of
any check or other item of payment by Bank shall not be considered a payment on
account until such check or other item of payment is honored when presented for
payment, in which event, said check or other item of payment shall be deemed to
have been paid to Bank two (2) calendar days after the date Bank actually
receives such check or other item of payment.

           4.3 Bank's security interest in Inventory shall attach to all
Inventory without further act on the part of Bank or Borrower. Upon Bank's
request during the continuance of an Event of Default Borrower will from time to
time at Borrower's expense pledge, assemble and deliver such Inventory to Bank
or to a third party as Bank's bailee; or hold the same in trust for Bank's
account or store the same in a warehouse in Bank's name; or deliver to Bank
documents of title representing said Inventory; or evidence of Bank's security
interest in some other manner acceptable to Bank.

           4.4 Borrower shall execute and deliver to Bank concurrently with
Borrower's execution of this Agreement, and at any time or times hereafter at
the request of Bank, all financing statements, continuation financing
statements, security agreements, mortgages, collateral assignments, certificates
of title, affidavits, reports, notices, schedules of accounts, letters of
authority and all other documents that Bank may request, in form satisfactory to
Bank, to perfect and maintain perfected Bank's security interest in the
Collateral and in order to fully consummate all of the transactions contemplated
under this Agreement. Borrower hereby irrevocably makes, constitutes and
appoints Bank (and any of Bank's officers, employees or agents designated by
Bank) as Borrower's true and lawful attorney-in-fact with owner to sign the name
of Borrower on any financing statements, continuation financing statements,
security agreement, mortgage, collateral assignment, certificate of title,
affidavit, letter of authority, notice of other similar documents which must be
executed and/or filed in order to perfect or continue perfected Bank's security
interest in the Collateral.

                            LOAN & SECURITY AGREEMENT

           Borrower shall make appropriate entries in Borrower's Books
disclosing Bank's security interest in the Receivables. Bank (through any of its
officers, employees or agents) all have the right at any time or times hereafter
during Borrower's usual business hours, or during the usual business hours of
any third party having control over the records of Borrower, to inspect and
verify Borrower's Books in order to verify the amount or condition of, or any
other matter, relating to, said Collateral and Borrower's financial condition.

           4.5 Borrower appoints Bank or any other person whom Bank may
designate as Borrower's attorney-in-fact, effective upon the occurrence of an
Event of Default, with power to endorse Borrower's name on any checks, notes,
acceptances, money order, drafts or other forms of payment or security that may
come into Bank's possession; to sign Borrower's name on any invoice or bill of
lading relating to any Receivables, on drafts against account debtors, on
schedules and assignments of Receivables, on verifications of Receivables and on
notices to account debtors; to establish a lock box arrangement and/or to notify
the post office authorities to change the address for delivery of Borrower's
mail addressed to Borrower to an address designated by Bank, to receive and open
all mail addressed to Borrower, and to retain all mail related to the Collateral
and forward all other mail to Borrower; to send, whether in writing or by
telephone, requests for verification of Receivables; and to do all things
necessary to carry out this Agreement. Borrower ratifies and approves all acts
of the attorney-in-fact. Neither Bank nor its attorney- in-fact will be liable
for any acts or omissions or for any error of judgment or mistake of fact or
law. This power being coupled with an interest, is irrevocable so long as any
Receivables in which Bank has a security interest remain unpaid and until the
Obligations have been fully satisfied.

           4.6 During the continuance of an Event of Default, in order to
protect or perfect any security interest which Borrower is granted hereunder,
Borrower may, in its sole discretion, upon notice to Borrower, discharge any
lien or encumbrance or bond the same, pay any insurance, maintain guards,
warehousemen, or any personnel to protect the Collateral, pay any service
bureau, or, obtain any records, and all costs for the same shall be added to the
Obligations and shall be payable on demand.

           4.7 Borrower agrees that Bank may provide information relating to
this Agreement or relating to Borrower to Bank's parent, affiliates,
subsidiaries and services providers.

        5. CONDITIONS PRECEDENT.

           5.1 Conditions precedent to the making of the loans and the extension
of the financial accommodations hereunder, Borrower shall execute, or cause to
be executed, and deliver to Bank, in form and substance satisfactory to Bank and
its counsel, the following:

               (a) This Agreement and other documents required by Bank, provided
that Bank shall not require any opinion of counsel in connection herewith;

               (b) Financing statements (Form UCC-1) in form satisfactory to
Bank for filing and recording with the appropriate governmental authorities;

               (c) Certified extracts from the minutes of the meeting of its
board of directors, authorizing the borrowings and the granting of the security
interest provided for herein and authorizing specific officers to execute and
deliver the agreements provided for herein;

                            LOAN & SECURITY AGREEMENT

               (d) A certificate of good standing showing that Borrower is in
good standing under the laws of the state of its incorporation and certificates
indicating that Borrower is qualified to transact business and is in good
standing in any other state in which it conducts business;

               (e) UCC searches, tax lien and litigation searches, fictitious
business statement filings, insurance certificates, notices or other similar
documents which Bank may require and in such form as Bank may require, in order
to reflect, perfect or protect Bank's first priority security interest in the
Collateral and in order to fully consummate all of the transactions contemplated
under this Agreement;

               (f) Evidence that Borrower has obtained insurance and acceptable
endorsements; and

               (g) Warranties and representations of officers.

        6. WARRANTIES REPRESENTATIONS AND COVENANTS.

           6.1 If so requested by Bank, Borrower shall, not more frequently than
once per calendar month, during the term hereof execute and deliver a Report of
Accounts Receivable or similar report, in form customarily used by Bank.
Borrower's Borrowing Base at all times pertinent hereto shall not be less than
the advances made hereunder when the Daily Balance exceeds $500,000. Bank shall
have the right to recompute Borrower's Borrowing Base in conformity with this
Agreement.

           6.2 If any warranty is breached as to any account previously included
in the Borrowing Base, or any such account is not paid in full by an account
debtor within ninety (90) days from the date of invoice and such failure relates
to more than twenty-five percent (25%) of outstanding Receivables from such
account debtor, or an account debtor disputes liability, or a petition in
bankruptcy or other application for relief under the Bankruptcy Code or any
other insolvency law is filed by or against an account debtor, or an account
debtor makes an assignment for the benefit of creditors, becomes insolvent,
fails or goes out of business, then Bank may deem ineligible any and all
accounts owing by that account debtor, and reduce Borrower's Borrowing Base by
the amount thereof Bank may retain its security interest in all Receivables and
accounts, whether eligible or ineligible, until all Obligations have been fully
paid and satisfied. Returns and allowances, if any, as between Borrower and its
customers, will be on the same basis and in accordance with the usual customary
practices of the Borrower, as they exist at this time. Borrower shall promptly
notify Bank of all disputes and claims, relating to the Collateral, in excess of
$50,000. During the continuance of an Event of Default, no discount, credit or
allowance shall be granted to any account debtor by Borrower and no return of
merchandise shall be accepted by Borrower without Bank's consent. Bank may,
during the continuance of an Event of Default, settle or adjust disputes and
claims directly with account debtors for amounts and upon terms which Bank
considers advisable, and in such cases Bank will credit Borrower's account with
only the net amounts received by Bank in payment of the accounts, after
deducting all Bank Expenses in connection therewith.

           6.3 Borrower warrants, represents, covenants and agrees that:

               (a) Borrower has good and marketable title to the Collateral.
Bank has and shall continue to have a first priority perfected security interest
in and to the Collateral. The Collateral shall at all times remain free and
clear of all liens, encumbrances and security interests (except those in favor
of Bank and Permitted Liens).

               (b) All Eligible Accounts are and will, at all times pertinent
hereto, be bona fide existing obligations created by the sale and delivery of
merchandise or the rendition of services to account debtors in the ordinary
course of business, free of liens, claims, encumbrances and security interests
(except as held by Bank and except as may be consented to, in writing, by Bank)
and are unconditionally owed to Borrower without defenses, disputes, offsets,
counterclaims, rights of return or cancellation, and Borrower shall have
received no notice of actual or imminent bankruptcy or insolvency of any account
debtor at the time an account due from such account debtor is assigned to Bank.

           6.4 At the time each Eligible Account is assigned to Bank, such
Eligible Account will be due and payable on terms set forth in Section 1.12, or
on such other terms approved in writing by Bank in advance of the creation of
such accounts and which are expressly set forth on the face of all invoices,
copies of which shall be held by Borrower as custodian for Bank, and no such
Eligible Account will then be past due.

           6.5 [Deleted]

           6.6 Borrower represents, warrants and covenants with Bank that
Borrower will not, without Bank's prior written consent:

               (a) Convey, sell, lease, transfer or otherwise dispose of

granted in the ordinary course of business and similar arrangements for the use

case an Event of Default does not exist before or after giving effect to such
Transfer;

               (b) Engage in any business, or permit any of its Subsidiaries to
engage in any business, other than the businesses currently engaged in by
Borrower and any business substantially similar or related thereto (or
incidental thereto). Borrower will not, without thirty (30) days prior written

capital stock or property of another Person; provided that without Bank's
consent, (i) any Subsidiary may merge into Borrower or another Subsidiary, and
(ii) Borrower may merge or consolidate with another entity, or acquire all or
substantially all of the capital stock or property of another Person where the
aggregate consideration in such merger, consideration or acquisition consists of
not more than Ten Million Dollars ($ 10,000,000) of Borrower's capital stock or
not more than Five Million Dollars ($5,000,000) in cash, so long as Borrower in
any case is the surviving entity after giving effect to such transaction.

any Indebtedness, or permit any Subsidiary so to do, other than Permitted

which violation could have a Material Adverse Effect or a material adverse
effect on the Collateral or the priority of Bank's Lien on the Collateral, or
permit any of its Subsidiaries to do any of the foregoing; or

           6.7 Borrower is not a merchant whose sales for resale of goods for
personal, family or household purposes exceeded seventy-five percent (75%) in
dollar volume of its total sales of all goods during the 12 months preceding the
filing by Bank of a financing statement describing the Collateral. At no time

sales.

           6.8 Except as disclosed in writing to Bank, Borrower's sole place of

               (b) Borrower is and shall at all times hereafter be a corporation
duly organized and existing in good standing under the laws of the state of its
incorporation and qualified and licensed to do business in California or any
other state in which it conducts its business;

               (c) Borrower has the right and power and is duly authorized to
enter into this Agreement; and

               (d) The execution by Borrower of this Agreement shall not
constitute a breach of any provision contained in Borrower's articles of
incorporation or by-laws.

           6.10 The execution of and performance by Borrower of all of the terms
and provisions contained in this Agreement shall not result in a breach of or
constitute an event of default under any agreement to which Borrower is now or
hereafter becomes a party.

           6.11 [Deleted]

           6.12 All assessments and taxes, whether real, personal or otherwise,
due or payable by, or imposed, levied or assessed against, Borrower or any of
its property have been paid, and shall hereafter be paid in full, before
delinquency. Borrower shall make due and timely payment or deposit of all
federal, state and local taxes, assessments or contributions required of it by
law, and will execute and deliver to Bank, on demand, appropriate certificates
attesting to the payment or deposit thereof. Borrower will make timely payment
or deposit of all F.I.C.A. payments and withholding taxes required of it by
applicable laws, and will upon request furnish Bank with proof satisfactory to
it that Borrower has made such payments or deposit. If Borrower fails to pay any
such assessment, tax, contribution, or make such deposit, or furnish the
required proof, Bank may, in its sole and absolute discretion, and without
notice to Borrower, (i) make payment of the same or any part thereof; or (ii)
set up such reserves in Borrower's account as Bank deems necessary to satisfy
the liability therefor, or both. Bank may conclusively rely on the usual
statements of the amount owing or other official statements issued by the
appropriate governmental agency. Each amount so paid or deposited by Banks shall
constitute a Bank Expense and an additional advance to Borrower.

shall be applied on account of the Obligations owing to Bank. To secure the

agents designated by Bank) as Borrower's attorney for the purpose of making,
selling and adjusting claims under such policies of insurance, endorsing the
name of Borrower or any check, draft, instrument or other item of payment for
the proceeds of such policies of insurance and for making all determinations and
decisions with respect to such policies of insurance. Borrower will not cancel

recover under such policy or policies of insurance required above or to pay any
premium in whole or in part relating thereto. Bank, without waiving or releasing

so, obtain and maintain such policies of insurance and pay such premiums and

therewith;

               (e) Without limiting Bank's rights under any security interest,
Bank is hereby granted a license or other right to use, without charge,

Collateral be present at any such sale;

               (h) Bank shall give notice of the disposition of the Collateral
as follows:

                   (i) Bank shall give the Borrower and each holder of a

for notice, a notice in writing of the time and place of public sale, or, if the
sale is a private sale or some disposition other than a public sale is to be
made of the Collateral, the time on or after which the private sale or the
disposition is to be made;

                   (ii) The notice shall be personally delivered or mailed,
postage prepaid, to Borrower's address appearing in this Agreement, at least
five (5) calendar days before the date fixed for the sale, or at least five (5)

interest in the Collateral shall be sent to such addresses as they have
furnished to Bank;

                   (iii) If the sale is to be a public sale, Bank shall also

any and all amounts maintained by Borrower as deposit accounts (as that term is
defined under 9105 of the Uniform Commercial Code) or other accounts that
Borrower maintains with Bank against the Obligations.

           8.2 Bank's rights and remedies under this Agreement and all other
agreements shall be cumulative. Bank shall have all other rights and remedies
not inconsistent herewith as provided by law or in equity. No exercise by Bank
of one right or remedy shall be deemed an election, and no waiver by Bank of any
default on Borrower's part shall be deemed a continuing waiver. No delay by Bank
shall constitute a waiver, election or acquiescence by Bank.

        9. TAXES AND EXPENSES REGARDING BORROWER'S PROPERTY.

           If Borrower fails to pay promptly when due to another person or
entity, monies which Borrower is required to pay by reason of any provision in
this Agreement, Bank may, but need not, pay the same and charge Borrower's
account therefor, and Borrower shall promptly reimburse Bank. All such sums
shall become additional indebtedness owing to Bank, shall bear interest at the
rate hereinabove provided, and shall be secured by all Collateral. Any payments
made by Bank shall not constitute (i) an agreement by it to make similar
payments in the future; or (ii) a waiver by Bank of any default under this
Agreement. Bank need not inquire as to, or contest the validity of, any such
expense, tax security interest, encumbrance or lien and the receipt of the usual

unless expressly provided to the contrary in another place, or (ii) if the
Borrower (or any of them) has (have) given or give(s) Bank a deed of trust or

(ii) as of such payment date, an amount equal to the product of the fraction
specified below times the sum of all remaining payments under the respective
Note, including the amount of any mandatory or optional payment required or
permitted to be paid by Borrower to Lender at the maturity of the Note
discounting to present value the amounts in (ii) at a rate of 6% per annum
compounded monthly on the basis of a 360 day year ("Discount Rate"). The
numerator of the fraction shall be the collateral value (as set forth on the
applicable Note) of the item and the denominator shall be the aggregate
collateral value of all items under the Note. Upon the making of such payments,
Lender shall release such item of Collateral from its lien hereunder.

SECTION 10. INSURANCE. Borrower at its expense shall keep the Collateral insured
against all risks of physical loss for at least the replacement value of the
Collateral and in no event for less than the amount payable following a Casualty
Occurrence (as provided in Section 9). Such insurance shall provide for a loss
payable endorsement to Lender and/or any assignee of Lender. Borrower shall
maintain commercial general liability insurance, including products liability
and completed -operations coverage, with respect to loss or damage for personal
injury, death or property damage in an amount not less than $2,000,000 in the
aggregate, naming Lender and/or

                                       5
<PAGE>   6

Lender's assignee as additional insured. Such insurance shall contain insurer's
agreement to give thirty (30) days' advance written notice to Lender before
cancellation or material change of any policy of insurance. Borrower will
provide Lender and any assignee of Lender with a certificate of insurance from
the insurer evidencing Lender's or such assignee's interest in the policy of
insurance. Such insurance shall cover any Casualty Occurrence to any unit of
Collateral. Notwithstanding anything in Section 9 or this Section 10 to the
contrary, this Security Agreement and Borrower's obligations hereunder shall
remain in full force and effect with respect to any unit of Collateral which is
not subject to a Casualty Occurrence. If Borrower fails to provide or maintain
insurance as required herein, Lender shall have the right but shall not be
obligated, to obtain such insurance. In that event Borrower shall pay to Lender
the cost thereof.

SECTION 11. MISCELLANEOUS AFFIRMATIVE COVENANTS. So long as any portion of the
Indebtedness is unpaid and as long as any of the Obligations are outstanding
Borrower will: (a) duly pay all governmental taxes and assessments at the time
they become due and payable; provided, however, Borrower may contest the same in
good faith so long as no payment default by Borrower has occurred and is
continuing; (b) comply with all applicable material governmental laws, rules and
regulations relating to its business and the Collateral where a failure to
comply would have a Material Adverse Effect; (c) take no action to adversely
affect Lender's security interest in the Collateral as a first and prior
perfected security interest (d) furnish Lender with its annual audited financial
statements within one hundred twenty (120) days following the end of Borrower's
fiscal year, unaudited quarterly financial statements within sixty (60) days
after the end of each fiscal quarter, and including an income statement and
balance sheet all of which shall be certified by an officer of Borrower as true
and correct and shall be prepared in accordance with generally accepted
accounting principles consistently applied, and such other information as Lender
may reasonably request; and (e) promptly (but in no event more than five (5)
days after the occurrence of such event) notify Lender of any change in
Borrower's condition during the commitment period which constitutes a Material
Adverse Effect, and of the occurrence of any Event of Default.

SECTION 12. INDEMNITIES. Borrower will protect, indemnify and save harmless
Lender and any assignees from and against all liabilities, obligations, claims,
damages, penalties, causes of action, costs and expenses (including reasonable
attorneys' fees and expenses), imposed upon or incurred by or asserted against
Lender or any assignee of Lender by Borrower or any third party by reason of the
occurrence or existence (or alleged occurrence or existence) of any act or event
relating to or caused by any portion of the Collateral, or its purchase,
acceptance, possession, use, maintenance or transportation, including without
limitation, consequential or special damages of any kind, any failure on the
part of Borrower to perform or comply with any of the terms of this Security
Agreement or any Note, claims for latent or other defects, claims for patent,
trademark or copyright infringement and claims for personal injury, death or
property damage, including those based on Lender's negligence or strict
liability in tort and excluding only those based on Lender's gross negligence or
willful misconduct. In the event that any action, suit or proceeding is brought
against Lender by reason of any such occurrence, Borrower, upon Lender's
request, will, at Borrower's expense, resist and defend such action, suit or
proceeding or cause the same to be resisted and defended by counsel designated
and approved by Lender. Borrower's obligations under this Section 12 shall
survive the payment in full of all the

                                       6
<PAGE>   7

Indebtedness and the performance of all Obligations with respect to acts or
events occurring or alleged to have occurred prior to the payment in full of all
the Indebtedness and the performance of all Obligations.

SECTION 13. TAXES. Borrower agrees to reimburse Lender (or pay directly if
instructed by Lender) and any assignee of Lender for, and to indemnify and hold
Lender and any assignee harmless from, all fees (including, but not limited to,
license, documentation, recording and registration fees), and all sales, use,
gross receipts, personal property, occupational, value added or other taxes,
levies, imposts, duties, assessments, charges, or withholdings of any nature
whatsoever, together with any penalties, fines, additions to tax, or interest
thereon (the foregoing collectively "Impositions"), except same as may be
attributable to Lender's income, arising at any time prior to or during the term
of any Notes or of this Security Agreement, or upon termination or early
termination of this Security Agreement and levied or imposed upon Lender
directly or otherwise by any Federal, state or local government in the United
States or by any foreign country or foreign or international taxing authority
upon or with respect to (a) the Collateral, (b) the exportation, importation,
registration, purchase, ownership, delivery, leasing, financing, possession,
use, operation, storage, maintenance, repair, return, sale, transfer of title,
or other disposition thereof, (c) the rentals, receipts, or earnings arising
from the Collateral, or any disposition of the rights to such rentals, receipts,
or earnings, (d) any payment pursuant to this Security Agreement or the Notes,
or (e) this Security Agreement the Notes or any transaction or any part hereof
or thereof.

SECTION 14. RELEASE OF LIENS. Upon payment of all of the Indebtedness and
performance of all of the Obligations, Lender shall execute UCC termination
statements and such other documents as Borrower shall reasonably request to
evidence the release of Lender's lien relating to the Collateral.

SECTION 15. ASSIGNMENT. WITHOUT LENDER'S PRIOR WRITTEN CONSENT WHICH CONSENT
WILL NOT BE UNREASONABLY WITHHELD OR DELAYED, BORROWER SHALL NOT (a) ASSIGN,
TRANSFER, PLEDGE, HYPOTHECATE OR OTHERWISE DISPOSE OF THIS SECURITY AGREEMENT,
ANY NOTE, ANY COLLATERAL, OR ANY INTEREST THEREIN, (b) LEASE OR LEND COLLATERAL
OR PERMIT IT TO BE USED BY ANYONE OTHER THAN BORROWER OR BORROWER'S EMPLOYEES,
CONTRACTORS AND AGENTS OR (c) MERGE INTO, CONSOLIDATE WITH OR CONVEY OR TRANSFER
ITS PROPERTIES SUBSTANTIALLY AS AN ENTIRETY TO ANY OTHER PERSON OR ENTITY EXCEPT
TO A SUCCESSOR IN INTEREST TO ALL OR SUBSTANTIALLY ALL OF THE BUSINESS OF
BORROWER; PROVIDED, HOWEVER, THAT, THE FINANCIAL CONDITION OF SUCH SUCCESSOR IS
GREATER THAN OR EQUAL TO BORROWER AS DETERMINED IN GOOD FAITH BY LENDER AND THE
SUCCESSOR'S BUSINESS AND ITS MAJOR INVESTORS ARE REASONABLY ACCEPTABLE TO
LENDER, OR SUCH ENTITY HAS OUTSTANDING RATED INVESTMENT GRADE PUBLIC DEBT.
LENDER MAY ASSIGN ANY OF THE NOTES, THIS SECURITY AGREEMENT OR ITS SECURITY
INTEREST IN ANY OR ALL COLLATERAL, OR ANY OR ALL OF THE ABOVE, IN WHOLE OR IN
PART TO ONE OR MORE ASSIGNEES OR SECURED PARTIES WITHOUT NOTICE TO BORROWER. If
Borrower is given notice of such assignment it agrees to acknowledge receipt
thereof in writing

                                       7
<PAGE>   8

and Borrower shall execute such additional documentation as Lender's assignee
and/or secured party shall reasonably require at Lender's expense. Each such
assignee and/or secured party shall have all of the rights, but (except as
provided in this Section 15) none of the obligations, of Lender under this
Security Agreement, unless such assignee or secured party expressly agrees to
assume such obligations in writing. Borrower shall not assert against any
assignee and/or secured party any defense, counterclaim or offset that Borrower
may have against Lender. Notwithstanding any such assignment, and providing no
Event of Default has occurred and is continuing, Lender, or its assignees,
secured par-ties, or their agents or assigns, shall not interfere with
Borrower's right to quietly enjoy use of Collateral subject to the terms and
conditions of this Security Agreement. Subject to the foregoing, the Notes and
this Security Agreement shall inure to the benefit of, and are binding upon, the
successors and assignees of the parties hereto. Borrower acknowledges that any
such assignment by Lender will not change Borrower's duties or obligations under
this Security Agreement and the Notes or increase any burden or risk on
Borrower.

SECTION 16. DEFAULT. (a) Events of Default. Any of the following events or
conditions shall constitute an "Event of Default" hereunder: (i) Borrower's
failure to pay any monies due to Lender hereunder or under any Note beyond the
tenth (10th) day after the same is due; (ii) Borrower's failure to comply with
its obligations under Section 10 or Section 15; (iii) any representation or
warranty of Borrower made in this Security Agreement or the Notes or in any
other agreement statement or certificate furnished to Lender in connection with
this Security Agreement or the Notes shall prove to have been incorrect in any
material respect when made or given; (iv) Borrower's failure to comply with or
perform any material term, covenant or condition of this Security Agreement or
any Note or under any other agreement between Borrower and Lender or under any
lease or mortgage of real property covering the location of the Collateral if
such failure to comply or perform is not cured by Borrower within thirty (30)
days after Borrower knows of the noncompliance or nonperformance or notice from
Lender or such longer period that Borrower is diligently attempting to effect
such cure; (v) seizure of any of the Collateral under legal process; (vi) the
filing by or against Borrower or any guarantor under any guaranty executed in
connection with this Security Agreement ("Guarantor") of a petition for
reorganization or liquidation under the Bankruptcy Code or any amendment thereto
or under any other insolvency law providing for the relief of debtors; (vii) the
voluntary or involuntary making of an assignment of a substantial portion of its
assets by Borrower or by any Guarantor for the benefit of its creditors, the
appointment of a receiver or trustee for Borrower or any Guarantor or for any of
Borrowers or Guarantor's assets, the institution by or against Borrower or any
Guarantor of any formal or informal proceeding for dissolution, liquidation,
settlement of claims against or winding up of the affairs of Borrower or any
Guarantor provided that in the case of all such involuntary proceedings, same
are not dismissed within sixty (60) days after commencement; (viii) the making
by Borrower or by any Guarantor of a transfer of all or a material portion of
Borrower's or Guarantor's assets or inventory not in the ordinary course of
business; or (ix) any default or breach by any Guarantor of any of the terms of
its guaranty to Lender in connection with this Security Agreement.

        (b) Remedies. If any Event of Default has occurred, Lender may in its
sole discretion exercise one or more of the following remedies with respect to
any or all of the Collateral: (i) declare due any or all of the aggregate sum of
all remaining payments under the Notes, including

                                       8
<PAGE>   9

the amount of any mandatory or optional payment required or permitted to be paid
by Borrower to Lender at the maturity of the Notes ("Remaining Payments"); (ii)
proceed by appropriate court action or actions either at law or in equity to
enforce Borrower's performance of the applicable covenants of the Notes and this
Security Agreement or to recover all damages and expenses incurred by Lender by
reason of an Event of Default; (iii) except as provided by law, without court
order or prior demand, enter upon the premises where the Collateral is located
and take immediate possession of and remove it without liability of Lender to
Borrower or any other person or entity; (iv) terminate this Security Agreement
and sell the Collateral at public or private sale, or otherwise dispose of,
hold, use or lease any or all of the Collateral in a commercially reasonable
manner; or (v) exercise any other right or remedy available to it under
applicable law. If Lender has declared due any or all of the Remaining Payments,
Borrower will pay immediately to Lender, without duplication, (A) the Remaining
Payments discounted to present value at the Discount Rate, (B) all amounts which
may be then due or accrued, and (C) all other amounts due under this Security
Agreement and under the Notes (Lender's Return, as referred to below, means the
amounts described in clauses (A), (B) and (C) above). The net proceeds of any
sale or lease of such Collateral will be credited against Lender's Return. The
net proceeds of a sale of the Collateral pursuant to this Section 16(b) is
defined as the sales price of the Collateral less selling expenses, including,
without limitation, costs of remarketing the Collateral and all refurbishing
costs and commissions paid with respect to such remarketing. The net proceeds of
a lease of the Collateral pursuant to this Section 16(b) is defined as the
amount equal to the monthly payments due under such lease (discounted to present
value at the Discount Rate) plus the residual value of the Collateral at the end
of the basic term of such lease, as reasonably determined by Lender, and
discounted at the Discount Rate.

At Lender's request, Borrower shall assemble the Collateral and make it
available to Lender at such time and location as Lender may reasonably
designate. Borrower waives any right it may have to redeem the Collateral.

Declaration that any or all amounts under this Security Agreement and/or the
Notes are immediately due and payable and Lender's taking possession of any or
all Equipment shall not terminate this Security Agreement or any of the Notes
unless Lender so notifies Borrower in writing. None of the above remedies is
intended to be exclusive but each is cumulative and may be enforced separately
or concurrently.

        (c) Application of Proceeds. The proceeds of any sale of all or any part
of the Collateral and the proceeds of any remedy afforded to Lender by this
Security Agreement shall be paid to and applied as follows:

            First, to the payment of reasonable costs and expenses of suit or
foreclosure, if any, and of the sale, if any, including, without limitation,
refurbishing costs, costs of remarketing and commissions related to,
remarketing, all Remedy Expenses, all expenses, liabilities and advances
incurred or made pursuant to this Security Agreement or any Note by Lender in
connection with foreclosure, suit, sale or enforcement of this Security
Agreement or the Notes, and taxes, assessments or liens superior to Lender's
security interest granted by this Security Agreement;

                                       9
<PAGE>   10

            Second, to the payment of all other amounts not described in item
Third below due under this Security Agreement and all Notes;

            Third, to pay Lender an amount equal to Lender's Return, to the
extent not previously paid by Borrower; and

            Fourth, to the payment of any surplus to Borrower or to whomever may
lawfully be entitled to receive it.

        (d) Effect of Delay, Waiver; Foreclosure on Collateral. No delay or
omission of Lender, in exercising any right or power arising from any Event of
Default shall prevent Lender from exercising that right or power if the Event of
Default continues. No waiver of an Event of Default, whether full or partial, by
Lender or such holder shall be taken to extend to any subsequent Event of
Default, or to impair the rights of Lender in respect of any damages suffered as
a result of the Event of Default. The giving, taking or enforcement of any other
or additional security, collateral or guaranty for the payment or discharge of
the Indebtedness and performance of the Obligations shall in no way operate to
prejudice, waive or affect the security interest created by this Security
Agreement or any rights, powers or remedies exercised hereunder or thereunder.
Lender shall not be required first to foreclose on the Collateral prior to
bringing an action against Borrower for sums owed to Lender under this Security
Agreement or under any Note.

SECTION 17. LATE PAYMENTS. Borrower shall pay Lender a late charge of 8% of any
payment in the ordinary course owed Lender by Borrower which is not paid when
due (taking into account applicable grace periods), for every month such payment
is not paid when due, but in no event an amount greater than the highest rate
permitted by applicable law. If such amounts have not been received by Lender at
Lender's place of business or by Lender's designated agent by the date such
amounts are due under this Security Agreement or the Note;, Lender shall bill
Borrower for such charges. Borrower acknowledges that invoices for amounts due
hereunder or under the Notes are sent by Lender for Borrower's convenience only.
Borrower's non-receipt of an invoice will not relieve Borrower of its obligation
to make payments hereunder or under the Notes.

SECTION 18. PAYMENTS BY LENDER. If Borrower shall fail to make any payment or
perform any act required hereunder (including, but not limited to, maintenance
of any insurance required by Section 10), then Lender may, but shall not be
required to, after such notice to Borrower as is reasonable under the
circumstances, make such payment or perform such act with the same effect as if
made or performed by Borrower. Borrower will upon demand reimburse Lender for
all sums paid and all reasonable costs and expenses incurred in connection with
the performance of any such act.

SECTION 19. FINANCING STATEMENTS. Borrower hereby appoints Lender (and each of
Lender's officers, employees or agents designated by Lender) with full power of
substitution by Lender, as Borrower's attorney, with power to execute and
deliver on Borrower's behalf, financing statements and other documents necessary
to perfect and/or give notice of Lender's security interest in any of the
Collateral. Notwithstanding the above, Borrower will, upon

                                       10
<PAGE>   11

Lender's request, execute all financing statements pursuant to the Uniform
Commercial Code and all such other documents reasonably requested by Lender to
perfect Lender's security interests hereunder. Borrower authorizes Lender to
file financing statements signed only by Lender (where such authorization is
permitted by law) at all places where Lender deems necessary.

SECTION 20. NATURE OF TRANSACTION. Lender makes no representation whatsoever,
express or implied, concerning the legal character of the transaction evidenced
hereby, for tax or any other purpose.

SECTION 21. SUSPENSION OF LENDER'S OBLIGATIONS. The obligations of Lender
hereunder will be suspended to the extent that Lender is hindered or prevented
from complying therewith because of labor disturbances, including but not
limited to strikes and lockouts, acts of God, fires, floods, storms, accidents,
industrial unrest, acts of war, insurrection, riot or civil disorder, any order,
decree, law or governmental regulations or interference, failure of the
manufacturer to deliver any item of Collateral or any cause whatsoever not
within the sole and exclusive control of Lender.

SECTION 22. LENDER'S EXPENSE. Borrower shall pay Lender all reasonable costs and
expenses including reasonable attorney's fees, litigation expenses and the fees
of collection agencies, incurred by Lender (a) in enforcing any of the terms,
conditions or provisions hereof and related to the exercise of its remedies
("Remedy Expenses"), and (b) in connection with any bankruptcy or post-judgment
proceeding, whether or not suit is filed and, in each and every action, suit or
proceeding, including any and all appeals and petitions therefrom.

SECTION 23. ALTERATIONS; ATTACHMENTS. No alterations or attachments shall be
made to the Collateral that would materially impair the value or function
thereof without Lender's prior written consent, which shall not be given for
changes that will adversely affect the reliability and utility of the Collateral
or which cannot be removed without damage to the Collateral, or which in any way
decrease the value of the Collateral for purposes of resale or lease. All
attachments and improvements to the Collateral shall be deemed to be
"Collateral" for purposes of the Security Agreement, and a first priority
security interest therein shall immediately vest in Lender.

SECTION 24. CHATTEL PAPER. (a) One executed copy of the Security Agreement will
be marked "Original" and all other counterparts will be duplicates. To the
extent if any, that this Security Agreement constitutes chattel paper (as such
term is defined in the Uniform Commercial Code as in effect in any applicable
jurisdiction) no security interest in the Security Agreement may be created in
any documents other than the "Original." (b) There shall be only one original of
each Note and it shall be marked "Original," and all other counterparts will be
duplicates. To the extent, if any, that any Notes to this Security Agreement
constitutes chattel paper (or as such term is defined in the Uniform Commercial
Code as in effect in any, applicable jurisdiction) no security interest in any
Note(s) may be created in any documents other than the "Original."

                                       11
<PAGE>   12

SECTION 25. COMMITMENT FEE. Borrower has paid to Lender a commitment fee ("Fee")
of $15,000. The Fee shall be applied by Lender first to reimburse Lender for all
out-of-pocket UCC and other search costs, inspections and labeling costs and
appraisal fees, if any, incurred by Lender, and then proportionally to the first
monthly payment for each Note hereunder in the proportion that the Collateral
value for such Note bears to Lender's entire commitment. However, the portion of
the Fee which is not applied to such monthly payments shall be non-refundable
except if Lender defaults in its obligation to fund Loans pursuant to Section 3.

SECTION 26. NOTICES. All notices hereunder shall be in writing, by registered
mail, or reliable messenger or delivery service (including overnight service)
and shall be directed, as the case may be, to Lender at 2401 Kerner Boulevard,
San Rafael, California 94901, Attention: Asset Management and to Borrower at 301
Science Drive, Moorpark, CA 93021, Attention: Frederic T. Boyer, or at such
other address as the parties may notify one another of in writing from time to
time.

SECTION 27. MISCELLANEOUS. (a) Borrower -shall provide Lender with such
corporate resolutions, financial statements and other documents as Lender shall
reasonably request from time to time. (b) Borrower represents that the
Collateral hereunder is used solely for business purposes. (c) Time is of the
essence with respect to this Security Agreement. (d) Borrower acknowledges that
Borrower has read this Security Agreement and the Notes, understands them and
agrees to be bound by their terms and further agrees that this Security
Agreement and the Notes constitute the entire agreement between Lender and
Borrower with respect to the subject matter hereof and supersede all previous
agreements, promises, or representations. (e) This Security Agreement and the
Notes may not be changed, altered or modified except by an instrument signed by
an officer or authorized representative of Lender and Borrower. (f) Any failure
of Lender to require strict performance by Borrower or any waiver by Lender of
any provision herein or in a Note shall not be construed as a consent or waiver
of any other breach of the same or any other provision. (g) If any provision of
this Security Agreement or any Note is held invalid, such invalidity shall not
affect any other provisions hereof or thereof. (h) The obligations of Borrower
to pay the Indebtedness and perform the Obligations shall survive the expiration
or earlier termination of this Security Agreement and each Note until all
Obligations of Borrower to Lender have been met and all liabilities of Borrower
to Lender and any assignee have been paid in full. (i) Borrower will notify
Lender at least 30 days before changing its name, principal place of business or
chief executive office. (j) Borrower will, at its expense, promptly execute and
deliver to Lender such documents and assurances (including financing statements)
and take such further action as Lender may reasonably request in order to carry
out the intent of this Security Agreement and Lender's rights and remedies.

SECTION 28. JURISDICTION AND WAIVER OF JURY TRIAL. This Security Agreement and
each Note shall be deemed to have been made under and shall be governed by the
laws of the State of California in all respects, including matters of
construction, validity and performance. At Lender's sole discretion, option and
election, jurisdiction and venue for any legal action between the parties
arising out of or relating to this Security Agreement or any Note shall be in

SO, HEREBY WAIVES ITS RIGHT TO TRIAL BY JURY IN ANY ACTION BROUGHT ON OR WITH
RESPECT TO THIS SECURITY AGREEMENT, ANY NOTE, ANY SECURITY DOCUMENTS, OR ANY
OTHER AGREEMENTS EXECUTED 1N CONNECTION HEREWITH.

SECTION 29. END OF LOAN POSITION. (a) General, Borrower shall be required to
choose a final payment or Note extension election ("End of Loan Position") at
the expiration of each Note's term. Borrower shall provide written notice of its
election to Lender at least 90 days prior to the end of the term of such Note.
That choice shall be an election of Borrower's End of Loan Position election for
all, but not less than all, of the Collateral under such Note under the
Security, Agreement.

In the event Borrower does not provide 90 days' prior written notice of its
election, Borrower shall be deemed to have elected Election No. 1.
