interest period on the amount prepaid had it not been prepaid, exceeds

          (ii) the interest which would have been recoverable by the Bank by

     (e) Each prepayment of an IBOR Rate Portion, whether voluntary, by reason
of acceleration or otherwise, will be accompanied by the amount of accrued

market, the eurodollar deposit market, or other appropriate money market
selected by the Bank for a period starting on the date on which it was prepaid
and ending on the last day of the Interest period for such Portion (or the
scheduled payment date for the amount prepaid, if earlier).

                                       4
<PAGE>

     The Bank will have no obligation to accept an election for an IBOR Rate
Portion if any of the following described events has occurred and is continuing:

          (i) Dollar deposits in the principal amount, and for periods equal to
the interest period, of an IBOR Rate Portion are not available in the offshore
dollar inter-bank market; or

          (ii) the IBOR Rate does not accurately reflect the cost of an IBOR
Rate Portion.

     3.4 Long Term Base Rate. The election of Long Term Base Rates shall be
subject to the following terms and requirements:

     (a) The "Long Term Base Rate" means the fixed interest rate per annum,
determined solely by the Bank on the first day of the applicable interest period
for the Portion, as the rate at which the Bank would be able to borrow funds in
the Money Market in the amount of Portion and with an interest payment frequency
and principal repayment schedule equal to the Portion and for a term equal to
the applicable interest period. The Long Term Base Rate shall include
adjustments for reserve requirements, federal deposit insurance, interest

     (c) The interest period during which the Long Term Base Rate will be in
effect will be one year or more.

     (d) Each Long Term Base Rate Portion will be for an amount not less than
Five Hundred Thousand Dollars ($500,000).

     (e) The Borrower may prepay the Long Term Base Rate Portion in whole or in
part in the minimum amount of Five Hundred Thousand Dollars ($500,000). The
Borrower will give the Bank irrevocable written notice of the Borrower's
intention to make the prepayment, specifying the date and amount of the
prepayment. The notice must be received by the Bank at least 5 banking days in
advance of the prepayment. All prepayments of principal on the Long Term Base
Rate Portion will be applied on the most remote payment of principal then
unpaid.

     (f) Each prepayment of a Long Term Base Rate Portion, whether voluntary, by
reason of acceleration or otherwise will be accompanied by payment of all
accrued interest on the amount of the prepayment and the prepayment fee
described below.

     (g) The prepayment fee will be the sum of fees calculated separately for
each Prepaid Installment, as follows:

                                       5
<PAGE>

          (i) The Bank will first determine the amount of interest which would
have accrued each month for the Prepaid Installment had it remained outstanding
until the applicable Original Payment Date, using the interest rate applicable
to the Long Term Base Rate Portion:

          (ii) The Bank will then subtract from each monthly interest amount
determined in (i), above, the amount of interest which would accrue for that
Prepaid Installment if it were reinvested from the date of prepayment through
the Original Payment Date, using the Treasury Rate.

          (iii) If (i) minus (ii) for the Prepaid Installment is greater than
zero, the Bank will discount the monthly differences to the date of prepayment
by the Treasury Rate. The Bank will then add together all of the discounted
monthly differences for the Prepaid Installment.

     (h) The following definitions will apply to the calculation of the
prepayment fee:

          "Original Payment Dates" mean the dates on which principal of the Long
Term Base Rate Portion would have been paid if there had been no prepayment. If
any of the principal would have been paid later than the end of the interest
period in effect at the time of prepayment, then the Original Payment Date for
that amount will be the last day of the interest period.

          "Prepaid Installment" means the amount of the prepaid principal of the
Long Term Base Rate Portion which would have been paid on a single Original
Payment Date.

          "Treasury Rate" means the interest rate yield for U.S. Government
Treasury Securities which the Bank determines could be obtained by reinvesting a
specified Prepaid Installment in such securities from the date of prepayment
through the Original Payment Date.

     (i) The Bank may adjust the Treasury Rate to reflect the compounding,
accrual basis, or other costs of the Long Term Base Rate Portion. Each of the
rates is the Bank's estimate only and the Bank is under no obligation to
actually reinvest any prepayment. The rates will be based on information from
either the Telerate or Reuters information services, The Wall Street Journal, or
other infonmation sources the Bank deems appropriate.

4. FEES AND EXPENSES

     4.1  Fees.

     (a) Waiver fee. If the Bank, at its discretion, agrees to waive or amend

borrow up to the full amount of credit provided under this Agreement. Each
Borrower will be liable for all extensions of credit made under this Agreement
to any other Borrower. Each request for an extension of credit will be made in
writing in a manner acceptable to the Bank, or by another means acceptable to
the Bank.

     6.2 Disbursements and Payments. Each disbursement by the Bank and each
payment by the Borrowers will be:

     (a) made at the Bank's branch (or other location) selected by the Bank from

<PAGE>

     6.3 Telephone and Telefax Authorizatlon.

     (a) The Bank may honor telephone or telefax Instructions for advances or
repayments or for the designation of optional interest rates given by any one of
the individuals authorized to sign loan agreements on behalf of each Borrower,
or any other individual designated by any one of such authorized signers.

     (b) Advances will be deposited in and repayments will be withdrawn from the
Borrower's account number 14591-05068, or such other accounts with the Bank as
designated in writing by the Borrowers.

     (c) The Borrowers indemnify and excuse the Bank (including its officers,
employees, and agents) from all liability, loss, and costs in connection with
any act resulting from telephone or telefax instnuctions the Bank reasonably
believes are made by any individual authorized by the Borrowers to give such
instructions. This indemnity and excuse will survive this Agreement's
termination.

     6.4 Direct Debit (Pre-Billing).

     (a) The Borrowers agree that the Bank will debit the Borrower's account
number 14591-05068, or such other of the Borrowers' accounts with the Bank as
designated in writing by the Borrowers the "Designated Account") on the date
each payment of principal and interest and any fees from the Borrowers becomes
due (the "Due Date"). If the Due Date is not a banking day, the Designated
Account will be debited on the next banking day.

     (b) Approximately 10 days prior to each Due Date, the Bank will mail to the
Borrowers a statement of the amounts that will be due on that Due Date (the
"Billed Amount"). The calculation will be made on the assumption that no new
extensions of credit or payments will be made between the date of the billing
statement and the Due Date, and that there will be no changes in the applicable
interest rate.

     (c) The Bank will debit the Designated Account for the Billed Amount,
regardless of the actual amount due on that date (the "Accrued Amount"). If the
Billed Amount debited to the Designated Account differs from the Accrued Amount,
the discrepancy will be treated as follows:

          (i) If the Billed Amount is less than the Accrued Amount, the Billed
Amount for the following Due Date will be increased by the amount of the
discrepancy. The Borrowers will not be in default by reason of any such
discrepancy.

          (ii) If the Billed Amount is more than the Accrued Amount, the Billed
Amount for the following Due Date will be decreased by the amount of the
discrepancy.  Regardless of any such discrepancy, interest will continue to
accrue based on the actual amount of principal outstanding without compounding.
The Bank will not pay the Borrowers interest on any overpayment.

                                       8
<PAGE>

     (d) The Borrowers will maintain sufficient funds in the Designated Account
to cover each debit. If there are insufficient funds in the Designated Account
on the date the Bank enters any debit authorized by this Agreement, the debit
will be reversed.

     6.5 Banking Days. Unless otherwise provided in this Agreement, a banking
day is a day other than a Saturday or a Sunday on which the Bank is open for
business in California. For amounts bearing interest at an offshore rate (if
any), a banking day is a day other than a Saturday or a Sunday on which the Bank
is open for business in California and dealing in offshore dollars. All payments
and disbursements which would be due on a day which is not a banking day will be
due on the next banking day. All payments received on a day which is not a
banking day will be applied to the credit on the next banking day.

     6.6 Taxes. If any payments to the Bank Under this Agreement are made from
outside the United States, the Borrowers will not deduct any foreign taxes from
any payments they make to the Bank. If any such taxes are imposed on any
payments made by the Borrowers (including payments under this paragraph), the
Borrowers will pay the taxes and will also pay to the Bank, at the time interest
is paid, any additional amount which the Bank specifies as necessary to preserve
the after-tax yield the Bank would have received if such taxes had not been
imposed. The Borrowers will confirm that they have paid the taxes by giving the
Bank official tax receipts (or notarized copies) within 30 days after the due
date.

     6.7 Additional Costs. The Borrowers will pay the Bank, on demand, for the
Bank's costs or losses arising from any statute or regulation, or any request or
requirement of a regulatory agency which is applicable to all national banks or
a class of all national banks. The costs and losses will be allocated to the
loan in a manner determined by the Bank, using any reasonable method. The costs
include the following:

     (a) any reserve or deposit requirements; and

     (b) any capital requirements relating to the Bank's assets and commitments
for credit.

     6.8 Interest Calculation. Except as otherwise stated in this Agreement, all
interest and fees, if any, will be computed on the basis of a 360-day year and
the actual number of days elapsed. This results in more interest or a higher fee
than if a 365-day year is used. Installments of principal which are not paid
when due under this Agreement shall continue to bear interest until paid.

     6.9 Default Rate. Upon the occurrence of any default under this Agreement,
principal amounts outstanding under this Agreement will at the option of the
Bank bear interest at a rate which is 2 percentage point(s) higher than the rate
of interest otherwise provided under this Agreement. This will not constitute a
waiver of any default.

     6.10 Interest Compounding. At the Bank's sole option in each instance, any
interest, fees or costs which are not paid when due under this Agreement shall
bear interest from the due date at the Bank's Prime Rate plus 2 percentage
points. This may result in compounding of interest.

                                       9

of such Borrower's key suppliers, vendors and customers with respect to the
"year 2000 problem" (that is, the inability of computers, as well as embedded
microchips in non-computing devices, to properly perform date-sensitive
functions with respect to certain dates prior to and after December 31, 1999).
Based on that review and inquiry, none of the Borrowers believes the year 2000
problem, including costs of remediation, will result in a material adverse
change in its business condition (financial or otherwise), operations,
properties or prospects, or ability to repay the credit. Each Borrower has
developed adequate contingency plans to ensure uninterrupted and unimpaired
business operation in the event of a failure of its own or a third party's
systems or equipment due to the year 2000 problem, including those of vendors,
customers, and suppliers, as well as a general failure of or interruption in its
communications and delivery infrastructure.

          For the quarter ending June 25, 2000 and thereafter  1.75 :1.0.

Borrower 2.

     "Total liabilities" means the sum of current liabilities plus long term
liabilities.

     "Tangible net worth" means the gross book value of Borrower 2's assets

indicated for each period specified below:

     For the fiscal quarter ending December 26, 1999    1.1:1.0
     For the fiscal quarter ending March 26, 2000       1.2:1.0
     For the fiscal quarter ending June 25, 2000
     and each fiscal quarter thereafter                 1.3:1.0.

     "Debt Service Coverage Ratio" is defined as the sum of net income after
taxes plus depreciation and amortization plus interest expense (including
payments on notes payable to related parties) minus dividends divided by the sum
of the current portion of long-term liabilities plus interest expense (including
payments on notes payable to related parties) plus principal payments made
against notes to related parties less $230,000 for quarter ending September
26, 1999, December 26, 1999, and March 26, 2000 or $130,000 for quarter ending
June 25, 2000. This ratio will be calculated at the end of each fiscal quarter,
using the results of that quarter and each of the 3 immediately preceding
quarters. The current portion of long term liabilities will be measured as of
the last day of the calculation period.
