      --------------------------

      Accounting terms not defined in this Agreement will be construed following
GAAP Calculations and determinations must be made following GAAP. The term
"financial statements" includes the notes and schedules.  The terms "including"
and "includes" always mean "including (or includes) without limitation," in this
or any Loan Document.  This Agreement shall be construed to impart upon Bank a
duty to act reasonably at all times.

2     LOAN AND TERMS OF PAYMENT
      -------------------------

2.1   Advances.

      Borrower will pay Bank the unpaid principal amount of all Advances and
interest on the unpaid principal amount of the Advances.

2.1.1 Revolving Advances.

      (a) Bank will make Advances not exceeding the Committed Revolving Line.
Amounts borrowed under this Section may be repaid and reborrowed during the term
of this Agreement.

      (b) To obtain an Advance, Borrower must notify Bank by facsimile or
telephone by 3:00 p.m. Pacific time on the Business Day the Advance is to be
made.  Borrower must promptly confirm the notification by delivering to Bank the
Payment/Advance Form attached as Exhibit A.  Bank will credit Advances to
Borrower's deposit account.  Bank may make Advances under this Agreement based
on instructions from a Responsible Officer or his or her designee or without
instructions if the Advances are necessary to meet Obligations which have become
due.  Bank may rely on any telephone notice given by a person whom Bank believes
is a Responsible Officer or designee. Borrower will indemnify Bank for any loss
Bank suffers due to reliance.

      (c) The Committed Revolving Line terminates on the Revolving Maturity
Date, when all Advances and other amounts due under this Agreement are
immediately payable.

2.2   Interest Rate, Payments.

      (a) Interest Rate.  Advances accrue interest on the outstanding principal
balance at a per annum rate equal to the Prime Rate.  After an Event of Default,
Obligations accrue interest at 5 percent above the rate effective immediately
before the Event of Default.  The interest rate increases or decreases when the
Prime Rate changes.  Interest is computed on a 360 day year for the actual
number of days elapsed.
 
      (b) Payments.  Interest due on the Committed Revolving Line is payable on
the 24th of each month.  Bank may debit any of Borrower's deposit accounts
including Account Number _____________________________ for principal and
interest payments or any amounts Borrower owes Bank.  Bank will notify Borrower
when it debits Borrower's accounts.  These debits are not a set-off.  Payments
received after 12:00 noon Pacific time are considered received at the opening of
business on the next Business Day.  When a payment is due on a day that is not a
Business Day, the payment is due the next Business Day and additional fees or
interest accrue.

8.2  Remedies Cumulative.

     Bank's rights and remedies under this Agreement, the Loan Documents, and
all other agreements are cumulative.  Bank has all rights and remedies provided
by law, or in equity. Bank's exercise of one right or remedy is not an election,

delay is not a waiver, election, or acquiescence. No waiver is effective unless
signed by Bank and then is only effective for the specific instance and purpose
for which it was given.

8.3  Demand Waiver.

     Borrower waives demand, notice of default or dishonor, notice of payment
and nonpayment, notice of any default, nonpayment at maturity, release,
