               Borrower promises to pay to the order of Bank, in lawful money of
the United States of America, the aggregate unpaid principal amount of all
Credit Extensions made by Bank to Borrower hereunder. Borrower shall also pay
interest on the unpaid principal amount of such Credit Extensions at rates in
accordance with the terms hereof.

               (a) Revolving Advances.
                   ------------------

                    (i) Subject to and upon the terms and conditions of this
Agreement, Borrower may request Advances in an aggregate outstanding amount not
to exceed the Revolving Line minus the aggregate face amount of all outstanding
                             -----
Letters of Credit. Subject to the terms and conditions of this Agreement,
amounts borrowed pursuant to this Section 2.1(a) may be repaid and reborrowed at

notify Bank by facsimile transmission or telephone no later than 3:00 p.m.
Pacific time, on the Business Day that the Advance is to be made. Each such
notification shall be promptly confirmed by a Payment/Advance Form in

                          ---------
under this Agreement, based upon instructions received from a Responsible
Officer or a designee of a Responsible Officer, or without instructions if in
Bank's discretion such Advances are necessary to meet Obligations which have
become due and remain unpaid. Bank shall be entitled to rely on any telephonic
notice given by a person who Bank reasonably believes to be a Responsible
Officer or a designee thereof, and Borrower shall indemnify and hold Bank
harmless for any damages or loss suffered by Bank as a result of such reliance.
Bank will credit the amount of Advances made under this Section 2.1(a) to
Borrower's deposit account. The obligation to repay the Advances is evidenced by
this Agreement and the revolving promissory note attached hereto as Exhibit B.
                                                                    ---------

under the Revolving Line shall be reduced by the aggregate limits of the
corporate credit cards issued to Borrower. In addition, upon the occurrence and
during the continuance of an Event of Default, Bank may, in its sole discretion,
charge as Advances any amounts that become due or owing to Bank in connection
with the Credit Card Services. All amounts owed pursuant to the Credit Card
Services Sublimit shall be debited monthly from Borrower's checking account with
Bank. The terms and conditions (including repayment and fees) of such Credit
Card Services shall be subject to the terms and conditions of the Bank's
standard forms of application and agreement for the Credit Card Services, which
Borrower hereby agrees to execute.

               (c) Letters of Credit Sublimit.

                                                                         -----
the aggregate amount of the outstanding Advances at any time, provided that the
aggregate face amount of all outstanding Letters of Credit shall not exceed Five
Hundred Thousand Dollars ($500,000). All Letters of Credit shall be, in form and

terms and conditions of Bank's form of standard application and letter of credit
agreement (the "Application"), which Borrower hereby agrees to execute,
including Bank's standard fee per annum on the face amount of each Letter of
Credit. On any drawn but unreimbursed Letter of Credit, the unreimbursed amount
shall be deemed an Advance under Section 2.1(a). No Letter of Credit shall have
an expiration date which is later than (i) the Revolving Maturity Date unless
Borrower secures in cash the obligations under such Letter of Credit on terms
acceptable to Bank, or (ii) one hundred twenty (120) days from the date of its
issuance.

<PAGE>

                    (ii) The obligation of Borrower to reimburse Bank for
drawings made under Letters of Credit shall be absolute, unconditional and
irrevocable, and shall be performed strictly in accordance with the terms of
this Agreement, the Application, and such Letters of Credit, under all
circumstances whatsoever. Borrower shall indemnify, defend, protect, and hold
Bank harmless from any loss, cost, expense or liability, including, without
limitation, reasonable attorneys' fees, arising out of or in connection with any

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

               (a) Interest Rates. Except as set forth in Section 2.2(b), the
                   --------------
Advances shall bear interest, on the outstanding Daily Balance thereof, at a
rate equal to 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. All payments shall be free and
clear of any taxes, withholdings, duties, impositions or other charges, other
than taxes due and payable by Bank on the income of Bank, to the end that Bank
will receive the entire amount of any Obligations payable hereunder, regardless
of source of payment.

               (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.

          2.3 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

expenses. The right to plead any and all statutes of limitations as a defense to
any demand hereunder is hereby waived to the full extent permitted by law.

     This Note is unsecured.

     This Note shall be governed by, and construed and enforced in accordance
with, the laws of the State of California, excluding conflict of laws principles
that would cause the application of the laws of any other jurisdiction.
