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

     2.1.1 REVOLVING ADVANCES. 
           ------------------ 
     (a) Subject to and upon the terms and conditions of this Agreement, Bank
  agrees to make Advances to Borrower in an aggregate outstanding amount not to
  exceed (i) the Committed Revolving Line or the Borrowing Base, whichever is
  less, minus (ii) the principal amount of all outstanding advances under that
  certain Letter Agreement dated March 25, 1996 between Borrower and Bank.
  Subject to the terms and conditions of this Agreement, amounts borrowed
  pursuant to this Section 2.1 may be repaid and reborrowed at any time during
  the term of this Agreement.

     (b) Whenever Borrower desires an Advance, Borrower will 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 substantially the form of
  EXHIBIT B hereto. Bank is authorized to make Advances 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 to Borrower's deposit account.

     (c) The Committed Revolving Line shall terminate on the Revolving Maturity
  Date, at which time all Advances under this Section 2.1 and other amounts due

Committed Revolving Line or (b) the Borrowing Base.

                                      -9-
   
     2.3     INTEREST RATES, PAYMENTS, AND CALCULATIONS.
             ------------------------------------------ 
 
     (a) INTEREST RATE. Except as set forth in Section 2.3(b), any Advances
shall bear interest, on the average daily balance thereof, at a per annum rate
equal to TWO (2.0) percentage points above the Prime Rate; PROVIDED, HOWEVER,
that effective the first day of the month following a Qualified Public Offering,
the interest rate will decrease to the Prime Rate.

     (b) DEFAULT RATE. All Obligations shall bear interest, from and after the
occurrence of an Event of Default, at a rate equal to five (5) 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 each Payment
Date. Borrower hereby authorizes Bank to debit any accounts with Bank,
including, without limitation, Account Number 700241676 for payments of
principal and interest due on the Obligations and any other amounts owing by
Borrower to Bank. Bank will notify Borrower of all debits which Bank has made
against Borrower's accounts. Any such debits against Borrower's accounts in no
way shall be deemed a set-off. 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 12:01 a.m. on 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, whether directed to Borrower's deposit account
with Bank or to the Obligations or otherwise, shall be immediately applied to
conditionally reduce Obligations, but shall not be considered a payment in
respect of the Obligations 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. A Facility Fee equal to TWELVE THOUSAND FIVE HUNDRED
Dollars ($12,500), which fee shall be due on the Closing Date and shall be fully
earned and non-refundable;

   11

                                      -10-
    
     (b) FINANCIAL EXAMINATION AND APPRAISAL FEES. 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 from time to time by Bank or its agents, provided that such audits
  won't be more than twice a year except in the Event of Default;

     (c) BANK EXPENSES. Upon demand from Bank, including, without limitation,
  upon the date hereof, all Bank Expenses incurred through the date hereof,
  including reasonable attorneys' fees and expenses, and, after the date hereof,
  all Bank Expenses, including reasonable attorneys' fees and expenses, as and
  when they become due.

     6. ADDITIONAL COSTS. In case any law, regulation, treaty or official
directive or the interpretation of 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):

     (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
the Bank's business of making credit extensions generally, 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. Except as otherwise set forth herein, this Agreement shall become
effective on the Closing Date and, subject to Section 12.7, shall continue in
full force and effect for a term ending on the Revolving Maturity Date.
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 of this Agreement, Bank's lien on the
Collateral shall remain in effect for so long as any Obligations are
outstanding.

   4. CREATION OF SECURITY INTEREST
      -----------------------------
     4.1 GRANT OF SECURITY INTEREST. Borrower grants and pledges to Bank a
continuing security interest in all presently existing and hereafter acquired or
arising Collateral in order to secure prompt payment of any and all Obligations
and in order to secure prompt performance by Borrower of each of its covenants
and duties under the Loan Documents; PROVIDED, HOWEVER, that effective the first
day of the month following a Qualified Public Offering, Bank shall release its
security interest in the Collateral except to the extent of specific equipment
financed by Bank pursuant to that certain Letter Agreement dated March 25, 1996
between Borrower and Bank, as amended. Except as set forth in the Schedule, such
security interest constitutes a valid, first priority security interest in the
presently existing Collateral, and will constitute a valid, first priority
security interest in Collateral acquired after the date hereof. Borrower
acknowledges that Bank may place a "hold" on any deposit account pledged as
Collateral to secure the Obligations. Notwithstanding termination of this
Agreement, Bank's Lien on the Collateral shall remain in effect for so long as
any Obligations are outstanding.

     4.2 DELIVERY OF ADDITIONAL DOCUMENTATION REQUIRED. Borrower shall from time
to time execute and deliver to Bank, at the request of Bank, all Negotiable
Collateral, all financing statements and other documents that Bank may
reasonably request, in form satisfactory to Bank, to perfect and continue
perfected Bank's security interests in the Collateral and in order to fully
consummate all of the transactions contemplated under the Loan Documents.

     4.3 RIGHT TO INSPECT. Bank (through any of its officers, employees, or
agents) shall have the right, upon reasonable prior notice, from time to time
during Borrower's usual business hours, to inspect Borrower's Books and to make
copies thereof and to check, test, and appraise the Collateral in order to
verify Borrower's financial condition or the amount, condition of, or any other
matter relating to, the Collateral.

   5. REPRESENTATIONS AND WARRANTIES. Borrower represents and warrants as

standing in, any state in which the conduct of its business or its ownership of
property requires that it be so qualified.

     5.2 DUE AUTHORIZATION; NO CONFLICT. The execution, delivery, and
performance of the Loan Documents are within Borrower's powers, have been duly
authorized, and are not in conflict with nor constitute a breach of any
provision contained in Borrower's Articles/Certificate of Incorporation or
Bylaws, nor will they constitute an event of default under any material
agreement to which Borrower is a party or by which Borrower is bound. Borrower
   14


                                      -13-

is not in default under any agreement to which it is a party or by which it is
bound, which default could have a Material Adverse Effect.

     5.3 NO PRIOR ENCUMBRANCES. Borrower has good and indefeasible title to the
Collateral, free and clear of Liens, except for Permitted Liens.

     5.4 BONA FIDE ELIGIBLE ACCOUNTS. The Eligible Accounts are bona fide

effect on Borrower's interest or Bank's security interest in the Collateral.

a material adverse change in the consolidated financial condition of Borrower

   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 in accordance with
applicable law, 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 any action by
Bank);

     (b) Cease advancing money or extending credit to or for the benefit of
Borrower under this Agreement or under any other agreement between Borrower and
Bank;

     (c) Settle or adjust disputes and claims directly with account debtors for
amounts, upon terms and in whatever order that Bank reasonably considers
advisable;

     (d) Without notice to or demand upon Borrower, make such payments and do
such acts as Bank considers necessary or reasonable to protect its security
interest in the Collateral. 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 to any of
Borrower's premises, Borrower hereby grants Bank a license to enter such
premises and to occupy the same, without charge in order to exercise any of
Bank's rights or remedies provided herein, at law, in equity, or otherwise;

     (e) Without notice to Borrower set off and apply to the Obligations any and
all (i) balances and deposits of Borrower held by Bank, or (ii) indebtedness at
any time owing to or for the credit or the account of Borrower held by Bank;

   23

                                      -22-

     (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for
sale, advertise for sale, and sell (in the manner provided for herein) the
Collateral. Bank is hereby granted a non-exclusive, royalty-free license or
other right, solely pursuant to the provisions of this Section 9.1, to use,
without charge, Borrower's labels, patents, copyrights, mask works, 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 the Bank's benefit;

     (g) Sell the Collateral at either a public or private sale, or both, 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 the proceeds thereof to the Obligations in
whatever manner or order if deems appropriate;

     (h) Bank may credit bid and purchase at any public sale, or at any private
sale as permitted by law; 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 and
lawful attorney to: (a) send requests for verification of Accounts or notify
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
assignments of Accounts, verifications of Accounts, and notices to account
debtors; (d) make, settle, and adjust all claims under and decisions with
respect to Borrower's policies of insurance; and (e) settle and adjust 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 4.2 regardless of whether an Event of Default has
occurred. 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.

     9.3 ACCOUNTS COLLECTION. Upon the occurrence and during the continuance of
an Event of Default, 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 if requested or required by Bank,
immediately deliver such payments to Bank in their original form as received
from the account debtor, with proper endorsements for deposit.
   24

                                      -23-
 
     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, 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
Committed Revolving Line 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 6.6 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.

     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 not in the possession of the bank
or its agent 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 expressly set forth herein 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, 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.

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

     10. NOTICES. Unless otherwise provided in this Agreement, all notices or
demands by any party relating to this Agreement or any other agreement entered
into in connection herewith shall be in writing and (except for financial
statements and other informational documents which may be sent by first-class
mail, postage prepaid) shall be personally delivered or sent by a recognized
overnight delivery service, by certified mail, postage prepaid, return receipt
requested, or by telefacsimile to Borrower or to Bank, as the case may be, at
