               (a)  Adjusted Rate. Any change in the interest rate resulting
                    -------------
from a change in the Base Rate shall be effective as of the opening of business
on the day on which such change in the Base Rate becomes effective.

               (b)  Default Rate. From and after the Termination Date, Advances
                    ------------
under the Revolving Facility shall bear interest at a rate equal to five
percentage points (5%) more than the interest rate that would have been
applicable hereunder. Anything herein to the contrary notwithstanding, interest
at the default rate shall be due and payable on demand but shall accrue from the
Termination Date until all Advances are paid in full.

          2.6  Repayment Terms. Interest only shall be due and payable on the
               ---------------
unpaid principal balance of the Revolving Facility, without claim, notice,
presentment or demand, in consecutive monthly installments on the first (1/st/)
day of each month commencing on the first (1/st/) day of the first (1/st/) full
calendar month following the Funding Date.

               (a)  Application of Payments. Each payment received by Bank shall
                    -----------------------
be credited as of its due date, without regard to its date of receipt by Bank,
first to interest accrued and unpaid as of such due date and the remainder to
principal, and interest shall cease upon the principal so credited. All interest
calculations shall be on a basis of a three hundred and sixty (360)-day year and
a thirty (30)-day month. Daily interest shall consist of the product of the
outstanding principal balance of the Revolving Facility times the annual
interest rate then in effect divided by 360, then multiplied by the number of
days for which the daily interest calculation is made. Interest paid for any
partial month shall be prorated based on a thirty (30)-day month and the actual
number of day elapsed. Interest shall be compounded monthly.

          2.7  Overadvances. If, at any time or for any reason, the amount of
               ------------
Obligations owed by Borrower to Bank pursuant to Section 2.1 of this Agreement
is greater than the lesser of (i) the Committed Line or (ii) the Borrowing Base,
Borrower shall immediately pay to Bank, in cash, the amount the Obligations
exceed the Committed Line or Borrowing Base.

          2.8  Termination of Revolving Facility. The Revolving Facility shall
               ---------------------------------
terminate on the Termination Date, at which time all unpaid principal, all
unpaid and accrued interest, and all other amounts due under the Revolving
Facility shall be immediately due and payable.

          2.9  Statements. With respect to each Advance, Bank is hereby
               ----------
authorized to note the date, principal amount, interest rate and Interest Period
applicable thereto, and any payments made thereon, on its books and records
(either manually or by electronic entry), which notations shall be conclusive
evidence of the information noted in the absence of manifest error. A failure by
Bank to record any such information shall not impair the Borrower's liability to
make payment when due. Bank shall render to Borrower each month a statement
setting forth the balance in Borrower's loan account maintained by Bank for
Borrower pursuant to the provisions of this Agreement, including principal,
interest, fees, costs and expenses. Each such statement shall be subject to
subsequent adjustment by Bank but shall, absent manifest errors or omissions, be
considered correct and deemed accepted by Borrower and conclusively binding upon
Borrower as an

                                      -11-

<PAGE>

account stated except to the extent that Bank receives a written notice from
Borrower of any specific exceptions of Borrower thereto within thirty (30) days
after the date such statement has been mailed by Bank. Until such time as Bank
shall have rendered to Borrower a written statement as provided above, the
balance in Borrower's loan account shall be presumptive evidence of the amounts
due and owing to Bank by Borrower.

          2.10 Ratification of Oblations. Debtor ratifies and reaffirms the
               -------------------------
Obligations, which are currently outstanding in the amount of $_______________,
without setoff, defense, or counterclaim. Borrower agrees fully and faithfully
to pay, perform and discharge, as and when payment, performance and discharge
are due, all of the Obligations under the Loan Agreement, as amended hereby. By
executing this Agreement, Borrower acknowledges and agrees that except as
supplemented or modified hereby, the Loan Documents are and shall remain in full
force and effect.

                                   Article III
           ADDITIONAL COSTS, LOCKBOX ACCOUNT AND CREDITING OF PAYMENTS

          3.1  Crediting Payments. Prior to the occurrence of an Event of
               ------------------
Default, Bank shall credit a wire transfer of funds, check or other item of
payment to such deposit account or Obligation as Borrower specifies. After the
occurrence of an Event of Default, the receipt by Bank of any wire transfer of
funds, check, or other item of payment shall be immediately applied to
conditionally reduce Obligations, but shall not be considered a payment on
account unless such payment is of immediately available federal funds or unless
and until such check or other item of payment is honored when presented for
payment. Notwithstanding anything to the contrary contained herein, any wire
transfer or payment received by Bank after 12:00 noon California time shall be
deemed to have been received by Bank as of the opening of business on the
immediately following Business Day. Whenever any payment to Bank under the Loan
Documents would otherwise be due (except by reason of acceleration) on a date
that is not a Business Day, such payment shall instead be due on the next
Business Day, and additional fees or interest, as the case may be, shall accrue
and be payable for the period of such extension.

          3.2  Lockbox Account. If there is an Event of Default, Borrower shall,
               ---------------
at Borrower's expense and in the manner requested by Bank, direct that
remittances and all other collections and proceeds of Accounts and other
Collateral be deposited into a non-interest bearing lock box account maintained
in Bank's name ("Lockbox Account"). In connection therewith, Borrower shall
execute such lockbox agreement as Bank shall require. Borrower shall maintain
the Lockbox Account with Bank, and Borrower hereby grants to Bank a security
interest in the Lockbox Account over which Borrower shall have no control and
into which the proceeds of all Collateral shall be deposited immediately upon
their receipt.

               (a)  Borrower and all of its affiliates, subsidiaries,
shareholders, directors, employees or agents shall, acting as trustee for Bank,
receive, as the property of Bank, any monies, checks, notes, drafts, or any
other payment relating to and/or proceeds of Accounts or other Collateral which
come into their possession or under their control and immediately upon receipt
thereof, shall deposit or cause the same to be deposited in the Lockbox Account,
or remit the same

                                      -12-

<PAGE>

or cause the same to be remitted, in kind, to Bank. In no event shall the same
be commingled with Borrower's own funds.

               (b)  Borrower authorizes Bank to accept, indorse and deposit on
behalf of Borrower any checks tendered by an account debtor "in full payment" of
its obligation to Borrower. Borrower shall not assert against Bank any claim
arising therefrom, irrespective of whether such action by Bank effects an accord
and satisfaction of Borrower's claims, under (S)3-311 of the UCC, or otherwise.

          3.3  Collateral Control Account. Bank may, on occasion, agree to
               --------------------------
permit Borrower to maintain a deposit account in addition to the Lockbox
Account, provided Bank (1) has been notified thereof by Borrower and Bank has
given written notice of Bank's security interest therein to the financial
institution where such account is located; and (2) such account is a blocked
account to which only Bank may have access.

          3.4  Financial Examination and Appraisal Fees. In the Event of
               ----------------------------------------
Default, Borrower shall pay Bank's customary fees and out-of-pocket expenses for
Bank's audits of Borrower's Accounts, and for each appraisal of Collateral and
financial analysis and examination of Borrower performed by Bank or its agents.

          3.5  Bank Expenses. In the Event of Default, Borrower shall pay all
               -------------
Bank Expenses incurred by Bank, including reasonable attorneys' fees and
expenses.

          3.6  Additional Costs. In case any change in any law, regulation,
               ----------------
treaty or official directive or the interpretation or application thereof by any
court or any governmental authority charged with the administration thereof or
the compliance with any guideline or request of any central bank or other
governmental authority (whether or not having the force of law), in each case
after the date of this Agreement: (a) subjects Bank to any tax with respect to
payments of principal or interest or any other amounts payable hereunder by
Borrower or otherwise with respect to the transactions contemplated hereby
(except for taxes on the overall net income of Bank imposed by the United States
of America or any political subdivision thereof); (b) imposes, modifies or deems
applicable any deposit insurance, reserve, special deposit or similar
requirement against assets held by, or deposits in or for the account of, or
loans by, Bank; or (c) imposes upon Bank any other condition with respect to its
performance under this Agreement, and the result of any of the foregoing is to
increase the cost to Bank, reduce the income receivable by Bank or impose any
expense upon Bank with respect to any loans, Bank shall notify Borrower thereof.
Borrower agrees to pay to Bank the amount of such increase in cost, reduction in
income or additional expense as and when such cost, reduction or expense is
incurred or determined, upon presentation by Bank of a statement of the amount
and setting forth Bank's calculation thereof, all in reasonable detail.

default could have a Material Adverse Effect.

          6.3  No Prior Encumbrances. Borrower has good and indefeasible title

Such acts shall include, without limitation, performing a comprehensive review
and assessment of all of Borrower's systems and adopting a detailed plan, with
itemized budget, for the remediation, monitoring and testing of such systems. As

Borrower's labels, patents, copyrights, rights of use of any name, trade
secrets, trade names, trademarks, service marks, and advertising matter, or any
property of a similar nature, as it pertains to the Collateral, in completing
production of, advertising for sale, and selling any Collateral and, in

account debtors of Bank's security interest in the Accounts; (b) endorse
Borrower's name on any checks or other forms of payment or security that may
come into Bank's possession; (c) sign Borrower's name on any invoice or bill of
lading relating to any Account, drafts against account debtors, schedules and

disputes and claims respecting the accounts directly with account debtors, for
amounts and upon terms which Bank determines to be reasonable; provided Bank may
exercise such power of attorney to sign the name of Borrower on any of the
documents described in Section 5.2 upon an Event of Default. The appointment of
Bank as Borrower's attorney in fact, and each and every one of Bank's rights and
powers, being coupled with an interest, is irrevocable until all of the
Obligations have been fully repaid and performed and Bank's obligation to
provide advances hereunder is terminated.

          11.3  Accounts Collection. At any time from the date of this
                -------------------
Agreement, Bank may notify any Person owing funds to Borrower of Bank's security
interest in such funds and verify the amount of such Account. Borrower shall
collect all amounts owing to Borrower for Bank, receive in trust all payments as
Bank's trustee, and immediately deliver such payments to Bank in their original
form as received from the account debtor, with proper endorsements for deposit.

          11.4  Bank Expenses. If Borrower fails to pay any amounts or furnish
                -------------
any required proof of payment due to third persons or entities, as required
under the terms of this Agreement, then Bank may do any or all of the following:
(a) make payment of the same or any part thereof; (b) set up such reserves under
the Revolving Facility as Bank deems necessary to protect Bank from the exposure
created by such failure; or (c) obtain and maintain insurance policies of the
type discussed in Section 7.11 of this Agreement, and take any action with
respect to such policies as Bank deems prudent. Any amounts so paid or deposited
by Bank shall constitute Bank Expenses, shall be immediately due and payable,
and shall bear interest at the then applicable rate hereinabove provided, and
shall be secured by the Collateral. Any payments made by Bank shall not
constitute an agreement by Bank to make similar payments in the future or a
waiver by Bank of any Event of Default under this Agreement.

          11.5  Bank's Liability for Collateral. So long as Bank complies with
                -------------------------------
reasonable banking practices, Bank shall not in any way or manner be liable or
responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage
thereto occurring or arising in any manner or fashion from any cause; (c) any
diminution in the value thereof; or (d) any act or default of any carrier,
warehouseman, bailee, forwarding agency, or other person whomsoever. All risk of
loss, damage or destruction of the Collateral shall be borne by Borrower.

          11.6  Remedies Cumulative. Bank's rights and remedies under this
                -------------------
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies not inconsistent herewith as
provided under the UCC, 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 Event of
Default on Borrower's part shall be deemed a continuing waiver. No delay by Bank
shall constitute a waiver, election, or acquiescence by it. No waiver by Bank
shall be effective unless made in a written document signed on behalf of Bank
and then shall be effective only in the specific instance and for the specific
purpose for which it was given.

          11.7  Demand; Protest. Borrower waives demand, protest, notice of
                ---------------
protest, notice of default or dishonor, notice of payment and
nonpayment, notice of any default, nonpayment at maturity, release, compromise,
settlement, extension, or renewal of accounts, documents,


                                       -26-

instruments, chattel paper, and guarantees at any time held by Bank on which
Borrower may in any way be liable.

                ---------------
harmless Bank and its officers, employees, and agents against: (a) all

party in connection with the transactions contemplated by this Agreement; and
(b) all losses or Bank Expenses in any way suffered, incurred, or paid by Bank
as a result of or in any way arising out of, following, or consequential to
transactions between Bank and Borrower whether under this Agreement, or
otherwise (including without limitation reasonable attorneys fees and expenses),
except for losses caused by Bank's gross negligence or willful misconduct.

          14.4  Time of Essence. Time is of the essence for the performance of
                ---------------
all obligations set forth in this Agreement.


          14.5  Severability of Provisions. In the event any one or more of the
                --------------------------
provisions contained in this Agreement is held to be invalid, illegal or
unenforceable in any respect, then such provision shall be ineffective only to

be affected or impaired thereby.

          14.6  Amendments. Neither this Agreement nor any provisions hereof may

this Agreement. Any waiver or consent so given shall be effective only in the
specific instance and for the specific purpose for which given.

          14.7  Entire Agreement. This Agreement, together with the Loan
                ----------------
Documents embodies the entire agreement and understanding among and between the
parties hereto, and supersedes all prior or contemporaneous agreements and

Bank or any third party to induce Borrower to execute this Agreement. No course
of dealing, course of performance or trade usage, and no parol evidence of any
nature, shall be used to supplement or modify any terms of this Agreement.

          14.8  Waiver. No failure to exercise and no delay in exercising any
                ------
right, power, or remedy hereunder shall impair any right, power, or remedy which
Bank may have, nor shall any such delay be construed to be a waiver of any of
such rights, powers, or remedies, or any acquiescence in any breach or default
hereunder; nor shall any waiver by Bank of any breach or default by Borrower
hereunder be deemed a waiver of any default or breach subsequently occurring.
All rights and remedies granted to Bank hereunder shall remain in full force and
effect notwithstanding any single or partial exercise of, or any discontinuance
of action begun to enforce, any such right or remedy. The rights and remedies
specified herein are cumulative and not exclusive of each other or of any rights
or remedies which Bank would otherwise have. Any waiver, permit, consent or


                                       -29-

                 ------------
counterparts, each of which shall be an original, with the same effect as if all
signatures were upon the same instrument. Delivery of an executed counterpart of
the signature page to this Agreement by telefacsimile shall be effective as
delivery of a manually executed counterpart of this Agreement, and any party
delivering such an executed counterpart of the signature page to this Agreement
by telefacsimile to any other party shall thereafter also promptly deliver a
manually executed counterpart of this Agreement to such other party, provided
                                                                     --------

the validity, enforceability, or binding effect of this Agreement.

          14.10  Interpretation. This Agreement and all agreements relating to
                 --------------
the subject matter hereof are the product of negotiation and preparation by and
among each party and its respective attorneys, and shall be construed
accordingly. The parties waive the provisions of California Civil Code (S) 1654.

          14.11  Survival. All covenants, representations and warranties made in
                 --------
this Agreement shall continue in full force and effect so long as any
Obligations remain outstanding. The obligations of Borrower to indemnify Bank
with respect to the expenses, damages, losses, costs and liabilities shall
survive until all applicable statute of limitations periods with respect to
actions that may be brought against Bank have run, provided that so long as the
obligations set forth in the first sentence of this Section 14.11 have been
satisfied, and Bank has no commitment to make any Advances or to make any other
loans to Borrower, Bank shall release all security interests granted hereunder
and redeliver all Collateral held by it in accordance with applicable law.

          14.12  Confidentiality. In handling any confidential information Bank
                 ---------------
shall exercise the same degree of care that it exercises with respect to its own
proprietary information of the same types to maintain the confidentiality of any
non-public information thereby received or received pursuant to this Agreement
except that disclosure of such information may be made (i) to the subsidiaries
or affiliates of Bank in connection with their present or prospective business
relations with Borrower, (ii) to prospective transferees or purchasers of any
interest in the Loans, provided that they have entered into a comparable
confidentiality agreement in favor of Borrower and have delivered a copy to
Borrower, (iii) as required by law, regulations, rule or order, subpoena,
judicial order or similar order, (iv) as may be required in connection with the
examination, audit or similar investigation of Bank and (v) as Bank may
determine in connection with the enforcement of any remedies hereunder.
Confidential information hereunder shall not include information that either:
(a) is in the public domain or in the knowledge or possession of Bank when
disclosed to Bank, or becomes part of the public domain after disclosure to Bank
through no fault of Bank; or (b) is disclosed to Bank by a third party, provided
Bank does not have actual knowledge that such third party is prohibited from
disclosing such information.

             CUSTOMER SIGNATURE

Notes:
     (1) Federal Government A/R - Customers that are pact of the Federal
         Government. This does not include state or local governments.
         Assignments of claim must be filed to include the receivables as
         eligible collateral, if they exceed $1,000.

     (2) Foreign A/R - includes any customer char is located outside of the
         United States. This includes foreign affiliates or divisions of
         domestic corporations. The originating locations of obligor purchase
         argue and payments remitted by than are the determining factors when
         labeling the obligor as a foreign account. Such A/R is not eligible
         unless backed by a confirmed L/C or by appropriate insurance with
         documentation acceptable to Comerica Bank-California.

     (3) Contra Accounts - Contras exist when there is a liability owing to a
         customer on your accounts receivable aging. A good way to reveal contra
         accounts is to compare the accounts receivable aging and accounts
         payable aging for like accounts at each month end.

     (4) Affiliate Accounts - An accounts receivable account in which you have a
         material interest is an affiliate account. Employee accounts, salesman
         accounts and related company accounts are all examples of affiliate
         accounts.

     (5) 25% Rule - If over 25% of the total for this customer is over 90 days,
         this will eliminate the customer entirely. Look down the Priors column
         (90 day) for outstanding dollars, when you reach a figure, mentally
         quadruple it. Compare to the total outstanding for that customer. If
         greater than total the account would be eliminated. Continue this
         process throughout the aging.

     (6) Concentrations - There is a concentration clause in every loan and
         security agreement. Based on your concentration allowance (usually 20%
         of total A/R) determine what would be ineligible by multiplying the
         coral A/R by 20% or whatever the percent allowed is. If any customer
         exceeds this amount, the excess is ineligible (less any portion is the
         priors or mention column) unless approved by Comerica Bank-California.

     (7) Other - Progress billings, service (maintenance) contracts,
         commissions, container receivables, non-trade receivables, Chapter 11
         receivables, any invoices (e.g. COD, cash account and miscellaneous)
         for which customer signed documentation is not available (verifying
         that shipment was received of services were provided).
