connection with any Letters of Credit, except for expenses caused by Bank's
gross negligence or willful misconduct.

               2.2  Overadvances. If the aggregate amount of the outstanding
                    ------------
Advances, plus the aggregate face amount of all outstanding Letters of Credit
plus the aggregate amount owing to Bank pursuant to the Credit Card Services,
exceeds the lesser of the Revolving Line or the Borrowing Base at any time,
Borrower shall immediately pay to Bank, in cash, the amount of such excess.

               2.3  Interest Rates, Payments, and Calculations.
                    ------------------------------------------

                    (a)  Interest Rates. Except as set forth in Section 2.3(b),
                         --------------
the Advances shall bear interest, on the outstanding Daily Balance thereof, at a
rate equal to one percent (1.00%) above the Prime Rate.

                    (b)  Late Fee; Default Rate. If any payment is not made
                         ----------------------
within ten (10) days after the date such payment is due, Borrower shall pay Bank
a late fee equal to the lesser of (i) five percent (5%) of the amount of such
unpaid amount or (ii) the maximum amount permitted to be charged under
applicable law. All Obligations shall bear interest, from and after the
occurrence and during the continuance of an Event of Default, at a rate equal to
three (3%) percentage points above the interest rate applicable immediately
prior to the occurrence of the Event of Default.

                    (c)  Payments. Interest hereunder shall be due and payable
                         --------
on the first calendar day of each month during the term hereof. Bank shall, at
its option, charge such interest, all Bank Expenses, and all Periodic Payments
against any of Borrower's deposit accounts or against the Revolving Line, in
which case those amounts shall thereafter accrue interest at the rate then
applicable hereunder. Any interest not paid when due shall be compounded by
becoming a part of the Obligations, and such interest shall thereafter accrue
interest at the rate then applicable hereunder.

                    (d)  Computation. In the event the Prime Rate is changed
                         -----------
from time to time hereafter, the applicable rate of interest hereunder shall be
increased or decreased, effective as of the day the Prime Rate is changed, by an
amount equal to such change in the Prime Rate. All interest chargeable under the
Loan Documents shall be computed on the basis of a three hundred sixty (360) day
year for the actual number of days elapsed.

               2.4  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 Pacific 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.

               2.5  Fees. Borrower shall pay to Bank the following:
                    ----

                    (a)  Facility Fee. On the Closing Date, a Facility Fee equal
                         ------------
to Ten Thousand Dollars ($10,000), which shall be nonrefundable; and

                    (b)  Commitment Fee. A Commitment Fee equal to three
                         --------------
twentieths of one percent (0.15%) per annum of the average unused portion of the
availability under the Revolving Line. Such fee shall be payable in quarterly
installments on the last day of each fiscal quarter or, in the case of the
quarter in which the

                                       8
<PAGE>

Revolving Maturity Date falls, on the Revolving Maturity Date. Each quarterly
installment shall be calculated on the average unused portion of the Revolving
Line during such fiscal quarter;

                    (c)  Bank Expenses. On the Closing Date, all Bank Expenses
                         -------------
incurred through the Closing Date, including reasonable attorneys' fees and
expenses and, after the Closing Date, all Bank Expenses, including reasonable
attorneys' fees and expenses, as and when they become due.

               2.6  Additional Costs. In case any law, regulation, treaty or
                    ----------------

any governmental authority charged with the administration thereof or the

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
the Obligations, 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, which statement shall be deemed
true and correct absent manifest error.

               2.7  Term. This Agreement shall become effective on the Closing
                    ----
Date and, subject to Section 12.7, shall continue in full force and effect for
so long as any Obligations remain outstanding or Bank has any obligation to make
Credit Extensions under this Agreement. Notwithstanding the foregoing, Bank
shall have the right to terminate its obligation to make Credit Extensions under
this Agreement immediately and without notice upon the occurrence and during the
continuance of an Event of Default. Notwithstanding termination, Bank's Lien on
the Collateral shall remain in effect for so long as any Obligations are
outstanding, other than contingent indemnity obligations under Section 12.2 of
this Agreement.

default cannot by its nature be cured within the ten (10) day period or cannot
after diligent attempts by Borrower be cured within such ten (10) day period,
and such default is likely to be cured within a reasonable time, then Borrower
shall have an additional reasonable period (which shall not in any case exceed
thirty (30) days) to attempt to cure such default, and within such reasonable
time period the failure to have cured such default shall not be deemed an Event
of Default (provided that no Credit Extensions will be required to be made

lien, levy, or assessment is filed of record with respect to any of Borrower's
assets by the United States Government, or any department, agency, or
instrumentality thereof, or by any state, county, municipal, or governmental
agency, and the same is not paid within ten (10) days after Borrower receives
notice thereof, provided that none of the foregoing shall constitute an Event of
Default where such action or event is stayed or an adequate bond has been posted
pending a good faith contest by Borrower (provided that no Credit Extensions
will be required to be made during such cure period);

          8.5  Insolvency. If Borrower becomes insolvent, or if an Insolvency
               ----------
Proceeding is commenced by Borrower, or if an Insolvency Proceeding is commenced

               ------------------
misstatement exists now or hereafter in any warranty or representation set forth

     9.   BANK'S RIGHTS AND REMEDIES.
          --------------------------

          9.1  Rights and Remedies. Upon the occurrence and during the
               -------------------
continuance of an Event of Default, Bank may, at its election, without notice of
its election and without demand, do any one or more of the following, all of
which are authorized by Borrower:

               (a)  Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the occurrence of an Event of Default described in
Section 8.5, all Obligations shall become immediately due and payable without

debtors for amounts, upon terms and in whatever order that Bank reasonably
considers advisable;

               (d)  Make such payments and do such acts as Bank considers

Borrower agrees to assemble the Collateral if Bank so requires, and to make the
Collateral available to Bank as Bank may designate. Borrower authorizes Bank to
enter the premises where the Collateral is located, to take and maintain
possession of the Collateral, or any part of it, and to pay, purchase, contest,
or compromise any encumbrance, charge, or lien which in Bank's determination
appears to be prior or superior to its security interest and to pay all expenses
incurred in connection therewith. With respect

                                       17
<PAGE>

to any of Borrower's owned premises, Borrower hereby grants Bank a license to

in equity, or otherwise;

               (e)  Set off and apply to the Obligations any and all (i)

prepare for sale, advertise for sale, and sell (in the manner provided for
herein) the Collateral. Bank is hereby granted a license or other right, solely
pursuant to the provisions of this Section 9.1, to use, without charge,
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
connection with Bank's exercise of its rights under this Section 9.1, Borrower's
rights under all licenses and all franchise agreements shall inure to Bank's
benefit;

               (g)  Dispose of the Collateral by way of one or more contracts or
transactions, for cash or on terms, in such manner and at such places (including
Borrower's premises) as Bank determines is commercially reasonable, and apply
any proceeds to the Obligations in whatever manner or order Bank deems
appropriate;

               (h)  Bank may credit bid and purchase at any public sale; and

               (i)  Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

          9.2  Power of Attorney. Effective only upon the occurrence and during
               -----------------
the continuance of an Event of Default, Borrower hereby irrevocably appoints
Bank (and any of Bank's designated officers, or employees) as Borrower's true

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

under and decisions with respect to Borrower's policies of insurance; (f) settle
and adjust disputes and claims respecting the accounts directly with account
debtors, for amounts and upon terms which Bank determines to be reasonable and
(g) to file, in its sole discretion, one or more financing or continuation
statements and amendments thereto, relative to any of the Collateral without the
signature of Borrower where permitted by law; provided Bank may exercise such
power of attorney to sign the name of Borrower on any of the documents described
in Section 4.2 regardless of whether an Event of Default has occurred, including
without limitation to modify, in its sole discretion, 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
and performed and Bank's obligation to provide Credit Extensions hereunder is
terminated.

          9.3  Accounts Collection. At any time during the term 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.

          9.4  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, which payment(s) effect or may effect Bank's
Collateral, then Bank may do any or all of the following after reasonable notice
to Borrower: (a) make payment of the same or any part thereof; (b) set up such
reserves under a loan facility in Section 2.1 as Bank deems necessary to protect
Bank from the exposure created by such failure; or (c) obtain and maintain

so paid or deposited by Bank shall constitute Bank Expenses, shall

                                       18
<PAGE>

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.

          9.5  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.

          9.6  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 Code, 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.

                -----------------------
the benefit of the respective successors and permitted assigns of each of the

obligations, rights and benefits hereunder.

          12.2  Indemnification. Borrower shall defend, indemnify and hold
                ---------------

obligations, demands, claims, and liabilities claimed or asserted by any other
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.

                ---------------
all obligations set forth in this Agreement.

          12.4  Severability of Provisions. Each provision of this Agreement
                --------------------------
shall be severable from every other provision of this Agreement for the purpose
of determining the legal enforceability of any specific provision.

          12.5  Amendments in Writing, Integration. Neither this Agreement nor
                ----------------------------------
the Loan Documents can be amended or terminated orally. All prior agreements,
understandings, representations, warranties, and negotiations between the
parties hereto with respect to the subject matter of this Agreement and the Loan
Documents, if any, are merged into this Agreement and the Loan Documents.

          12.6  Counterparts.  This Agreement may be executed in any number of
                ------------
counterparts and by different parties on separate counterparts, each of which,
when executed and delivered, shall be deemed to be an original, and all of
which, when taken together, shall constitute but one and the same Agreement.

          12.7  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 described
in Section 12.2 shall survive until all applicable statute of limitations
periods with respect to actions that may be brought against Bank have run.

                                  EXHIBIT A-1
                                  -----------

     The Collateral shall consist of all right, title and interest of Borrower
in and to the following:

     All personal property of Borrower (herein referred to as "Borrower" or
"Debtor") whether presently existing or hereafter created or acquired, and
wherever located, including, but not limited to:

          (a)  all accounts (including health-care-insurance receivables),
chattel paper (including tangible and electronic chattel paper), deposit
accounts, documents (including negotiable documents), equipment (including all
accessions and additions thereto), general intangibles (including payment
intangibles and software), goods (including fixtures), instruments (including
promissory notes), inventory (including all goods held for sale or lease or to
be furnished under a contract of service, and including returns and
repossessions), investment property (including securities and securities
entitlements), letter of credit rights, money, and all of Debtor's books and
records with respect to any of the foregoing, and the computers and equipment
containing said books and records; and

          (b)  any and all cash proceeds and/or noncash proceeds of any of the
foregoing, including, without limitation, insurance proceeds, and all supporting
obligations and the security therefor or for any right to payment.  All terms
above have the meanings given to them in the California Uniform Commercial Code,
as amended or supplemented from time to time, including revised Division 9 of
the Uniform Commercial Code-Secured Transactions, added by Stats. 1999, c.991
(S.B. 45), Section 35, operative July 1, 2001.

          Notwithstanding the foregoing, the Collateral shall not include any
copyrights, patents, trademarks, servicemarks and applications therefor, now
owned or hereafter acquired, or any claims for damages by way of any past,
present and future infringement of any of the foregoing (collectively, the
"Intellectual Property"); provided, however, that the Collateral shall include
all accounts and general intangibles that consist of rights to payment and
proceeds from the sale, licensing or disposition of all or any part, or rights
in, the foregoing (the "Rights to Payment").  Notwithstanding the foregoing, if
a judicial authority (including a U.S. Bankruptcy Court) holds that a security
interest in the underlying Intellectual Property is necessary to have a security
interest in the Rights to Payment, then the Collateral shall automatically, and
effective as of the Closing Date, include the Intellectual Property to the
extent necessary to permit perfection of Bank's security interest in the Rights
to Payment.
