the date hereof, being herein collectively called the "Existing Loan
Agreement").

    C.   In connection with the Existing Loan Agreement, Borrower has granted
Bank a security interest in substantially all of Borrower's property, pursuant
to that certain Commercial Security Agreement, dated as of August 20, 1993,

For purposes of this Agreement, "Borrowing Base" shall mean an amount equal to
(i) eighty percent (80%) of Eligible Accounts plus (ii) the lesser of fifty
percent (50%) of the value of Borrower's Eligible Inventory (valued at the lower

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. 
Notwithstanding anything to the contrary contained in this Section 2.1, Borrower
shall be permitted to incur (and to allow to remain outstanding) Obligations of
not more than $500,000 in excess of that permitted by the first two sentences of
this Section 2.1 until December 23, 1996, upon which date and thereafter there

<PAGE>

remain outstanding Obligations in excess of that permitted by the first two
sentences of this Section 2.1.

          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

EXHIBIT B hereto.  Bank is authorized to make Advances under this Agreement,
based upon instructions received from 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, 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.

          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
under this Agreement (except as otherwise expressly specified herein) shall be
immediately due and payable.

          2    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, at a rate equal
to two (2) percentage points above 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 three
percentage points above the interest rate applicable immediately prior to the
occurrence of the Event of Default.

               (c)       PAYMENTS.  Accrued interest hereunder shall be due and
payable on the Payment Date of each month during the term hereof.  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)   LOCKBOX.  Borrower shall maintain a lockbox account (the
"Lockbox") with Bank and shall cause all of Borrower's accounts receivable
collections to be remitted directly to the Lockbox.  Bank will transfer good
funds in the Lockbox to a cash collateral account (the "Cash Collateral
Account").  Borrower hereby grants Bank a security interest in 


                                      -12-

<PAGE>

the Lockbox and Cash Collateral Account to secure the Obligations.  Bank shall
have exclusive possession, dominion, and control over the Lockbox and Cash
Collateral Account.  Borrower may request that funds in the Cash Collateral
Account either be released to Borrower or applied to pay the Obligations;
PROVIDED that each such request shall be in writing and shall be accompanied by
a fully completed Daily Transaction Report in the form heretofore provided by
the Bank to Borrower and FURTHER PROVIDED that Bank may at any time and from
time to time in its sole and absolute discretion apply any and all funds in the
Lockbox or Cash Collateral Account toward payment of the Obligations in such
order of priority as shall be determined by Bank.

               (e)       DIRECT DEBIT.

                    (i)    The Borrower agrees that interest and principal
payments and any fees will be deducted automatically on the Payment Dates,
Maturity Date or other applicable due dates, as the case may be, from the
Borrower's account number 0400 994070, or such other of the Borrower's accounts
with the Bank as designated in writing by the Borrower.

                    (ii)        The Bank will debit such account on the dates
the payments become due.  If a due date does not fall on a banking day, the Bank
will debit the account on the first banking day following the due date.

                    (iii)       The Borrower will maintain sufficient funds in
the account on the dates the Bank enters debits authorized by this Agreement. 
If there are insufficient funds in the account on the date the Bank enters any
debit authorized by this Agreement, the debit will be reversed.

               (f)       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.

          3    CREDITING PAYMENTS.  No payment shall be considered a payment on
account 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 


                                      -13-

<PAGE>

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.

          4    FEES.  Borrower shall pay to Bank the following:

               (a)       FINANCIAL EXAMINATION AND APPRAISAL FEES.  Bank's
reasonable and customary fees and out-of-pocket expenses for Bank's audits of
Borrower's Accounts and Inventory, and for each appraisal of Collateral and

in the exercise of its absolute discretion); and

               (b)       BANK EXPENSES.  Upon demand by Bank, all Bank Expenses,
including, without limitation, all Bank Expenses incurred through the date
hereof (except to the extent such expenses are included as Existing Non-

          5    ADDITIONAL COSTS.  In case 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):

               (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 (including taxes on capital gains, if any,
resulting from the sale or other disposition of the Exchange Shares) 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 


                                      -14-

<PAGE>

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

          6    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 Advances 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.

by $1.52 (the "Exchange Shares") and in exchange for such issuance and in
consideration therefor, Bank shall cancel that portion of the Existing
Obligations represented by the Exchange Amount and thereafter the Exchange
Amount shall be deemed to have been satisfied in full.

               (b)   CLOSING. The Exchange shall occur contemporaneously upon
the effectiveness of this Agreement pursuant to Section 3.1.  On the Closing
Date, Borrower will deliver to Bank a share certificate registered in the name

securities laws, each certificate representing the Exchange Shares shall be

relating to the Securities Act of 1933 endorsed on a stock certificate pursuant
to paragraph 4.2 of this Agreement and the stop transfer instructions with
respect to the Exchange Shares represented by such certificate shall be removed
and Borrower shall issue a certificate without such legend to the holder of such
shares if such shares are included in a registration statement declared
effective by the Securities and Exchange Commission and a prospectus meeting the

Borrower or any duly authorized committee thereof (PROVIDED FURTHER that the
aggregate amount of all such Common Stock and Common Stock for which such
options, bonuses and other awards are exercisable does not exceed 5% of the
Common Stock outstanding on the date hereof), or (C) issue additional shares of
Common Stock (but not Options) if Borrower also, without any further
consideration being paid or payable by Bank,  contemporaneously issues
additional shares of Common Stock to Bank, so that after giving effect to both
such issuances, the Bank Share Percentage will not be less than the Minimum
Percentage.

                    (ii) If there shall be any consolidation or merger to which
Borrower is a party, other than a consolidation or a merger of which Borrower is
the continuing corporation and which does not result in any reclassification of,
or change in, outstanding shares of Common Stock, or any sale or conveyance of
the property of Borrower as an entirety or substantially as an entirety, or any
recapitalization of Borrower (any such event being called a "Capital
Reorganization"), then, effective upon the effective date of such Capital
Reorganization, the provisions of this Section 2.7(h) shall no longer apply to
the Common Stock, but shall instead apply to the stock and other securities
which the Bank or its Affiliates are entitled to receive pursuant to such
Capital Reorganization.  As a condition to effecting any Capital Reorganization,
Borrower or the successor or surviving corporation, as the case may be, shall
execute and deliver to 


                                      -17-

Bank and/or its Affiliates an agreement as to the Bank or such Affiliates with
rights in accordance with this Section 2.7(h),

providing, to the extent of any right to issuance of additional equity
securities hereunder, for issuance rights as nearly equivalent as may be
practicable to the adjustments provided for in this Section 2.7(h).  The
provisions of this Section 2.7(h) shall similarly apply to successive capital
reorganizations.

    4.   CREATION OF SECURITY INTEREST

         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 repayment 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.  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.  The security interest granted hereby is a continuation of the
security interests granted pursuant to the Existing Loan Documents.

         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.

         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 follows: 

         1    DUE ORGANIZATION AND QUALIFICATION.  Borrower and each Subsidiary
(if any) is a corporation duly existing and in good standing under the laws of
its state of incorporation and qualified and licensed to do business in, and is
in good standing in, any state in which the conduct of its business or its
ownership of property requires that it be so qualified, except where the failure
to be so qualified would not have a Material Adverse Effect.  On the Closing
Date, Borrower has no Subsidiaries.

                                         -19-


<PAGE>

         2    DUE AUTHORIZATION; NO CONFLICT.  The execution, delivery, and
performance of the Loan Documents are within Borrower's corporate powers, have
been duly authorized, and are not in conflict with nor constitute a breach of
any provision contained in Borrower's Articles 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 is not in default
under any agreement to which it is a party or by which it is bound, which
default would have, or is likely to cause, a Material Adverse Effect.

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

         4    BONA FIDE ELIGIBLE ACCOUNTS.  The Eligible Accounts are bona fide
existing obligations.  The property giving rise to such Eligible Accounts has
been delivered to the account debtor or to the account debtor's agent for
immediate shipment to and unconditional acceptance by the account debtor. 
Borrower has not received notice of actual or imminent Insolvency Proceeding of
any account debtor that is included in any Borrowing Base Certificate as an
Eligible Account.

         5    MERCHANTABLE INVENTORY.  All Eligible Inventory is in all
material respects of good and marketable quality, free from all material
defects.

         6    NAME; LOCATION OF CHIEF EXECUTIVE OFFICE.  Except as disclosed in
the Schedule, Borrower has not done business under any name other than that
specified on the signature page hereof within the last five years.  The chief
executive office of Borrower is located at the address indicated in Section 10
hereof.

         7    LITIGATION.  Except as set forth in the Schedule, there are no
actions or proceedings pending by or against Borrower or any Subsidiary before
any court or administrative agency in which an adverse decision would have, or
is likely to cause, a Material Adverse Effect.  Borrower does not have knowledge
of any such pending or threatened actions or proceedings.



                                         -20-

<PAGE>

         8    NO MATERIAL ADVERSE CHANGE IN FINANCIAL STATEMENTS.  All
consolidated financial statements related to Borrower and any Subsidiary that
have been delivered by Borrower to Bank fairly present in all material respects
Borrower's consolidated financial condition as of the date thereof and
Borrower's consolidated results of operations for the period then ended.  Since
the date of the most recent of such financial statements submitted to Bank there
has been no change, event, or condition which has had, or is likely to result
in, a Material Adverse Effect.

         9    REGULATORY COMPLIANCE.  Borrower and each Subsidiary has met the
minimum funding requirements of ERISA with respect to any employee benefit plans
subject to ERISA.  No event has occurred resulting from Borrower's failure to
comply with ERISA that is reasonably likely to result in Borrower's incurring
any liability that would have, or is likely to cause, a Material Adverse Effect.
Borrower is not an "investment company" or a company "controlled" by an
"investment company" within the meaning of the Investment Company Act of 1940. 
Borrower is not engaged principally, or as one of the important activities, in
the business of extending credit for the purpose of purchasing or carrying
margin stock (within the meaning of Regulations G, T and U of the Board of
Governors of the Federal Reserve System).  Borrower has complied with all the
provisions of the Federal Fair Labor Standards Act.  Borrower has not violated
any statutes, laws, ordinances or rules applicable to it, violation of which
would have, or is likely to cause, a Material Adverse Effect.

         10   ENVIRONMENTAL CONDITION.  None of Borrower's or any Subsidiary's
properties or assets has ever been used by Borrower or any Subsidiary or, to the
best of Borrower's knowledge, by previous owners or operators, in the disposal
of, or to produce, store, handle, treat, release, or transport, any hazardous
waste or hazardous substance other than in accordance with applicable law; to
the best of Borrower's knowledge, none of Borrower's properties or assets has
ever been designated or identified in any manner pursuant to any environmental
protection statute as a hazardous waste or hazardous substance disposal site, or
a candidate for closure pursuant to any environmental protection statute; no
lien arising under any environmental protection statute has attached to any
revenues or to any real or personal property owned by Borrower or any
Subsidiary; and neither Borrower nor any Subsidiary has received a summons,
citation, notice, or directive from the Environmental Protection Agency or any
other federal, state or other governmental agency concerning any action or
omission by Borrower or any Subsidiary resulting in the releasing, or otherwise
disposing of hazardous waste or hazardous substances into the environment.

         11   TAXES.  Borrower and each Subsidiary has filed or caused to be
filed all tax returns required to be filed, and has paid, or has made adequate
provision for the payment of, all taxes reflected therein.

         12   SUBSIDIARIES.  Borrower does not own any stock, partnership
interest or other equity securities of any Person, except for Permitted
Investments.

         13   GOVERNMENT CONSENTS.  Borrower and each Subsidiary has obtained
all consents, approvals and authorizations of, made all declarations or filings
with, and given all notices to, all governmental authorities that are material
to the continued operation of Borrower's business as currently conducted.

         14   FULL DISCLOSURE.  No representation, warranty or other statement
made by Borrower in any certificate or written statement furnished to Bank
contains any untrue statement of a material fact or omits to state a material
fact necessary in order to make the statements contained in such certificates or
statements not misleading.

         15   CAPITALIZATION.  The authorized, issued and outstanding capital
stock of Borrower is as set forth on Exhibit E.  All of such issued and
outstanding shares of capital stock have been duly authorized and validly issued
and are fully paid and nonassessable.  Except as set forth on Exhibit E, there
are no equity securities of any class of Borrower issued, reserved for issuance
or outstanding and Borrower has no commitment or obligation to issue, deliver or
sell, or cause to be issued, delivered or sold any shares of the capital stock
or other securities of Borrower.  On the Closing Date, after giving effect to
all Common Stock and Options issued or contemplated to be issued by the Company,
including any such issuances in connection with Section 6.8 of this Agreement or
the private placement now being pursued by the Company, the Bank Share
Percentage shall not be less than 8.5%.

         16   VALIDITY OF STOCK.  The Exchange Shares are validly issued, fully
paid, and nonassessable, and are free of any liens or encumbrances; 
PROVIDED that the Exchange Shares may be subject to restrictions on transfer
under state and/or federal securities laws and otherwise as set forth in this
Agreement.

    6.   AFFIRMATIVE COVENANTS

         Borrower covenants and agrees that, until payment in full of all
outstanding Obligations, and for so long as Bank may

have any commitment to make an Advance hereunder, Borrower shall do all of the
following:

         1    GOOD STANDING.  Borrower shall maintain Borrower's and each
Subsidiaries' corporate existence and good standing in its jurisdiction of
incorporation and maintain qualification in each jurisdiction in which the
failure to so qualify would have, or is likely to cause, a Material Adverse
Effect.  Borrower shall maintain, and shall cause each of its Subsidiaries to
maintain, to the extent consistent with prudent management of Borrower's
business, in force all licenses, approvals and agreements, the loss of which
could have a Material Adverse Effect.

         2    GOVERNMENT COMPLIANCE.  Borrower shall meet, and shall cause each
Subsidiary to meet, the minimum funding requirements of ERISA with respect to
any employee benefit plans subject to ERISA.  Borrower shall comply, and shall
cause each Subsidiary to comply, with all statutes, laws, ordinances and
government rules and regulations to which it is subject, noncompliance with
which could have a Material Adverse Effect.

         3    FINANCIAL STATEMENTS, REPORTS, CERTIFICATES.  Borrower shall
deliver to Bank:

              (a)  as soon as available, but in no event later than thirty (30)

<PAGE>

within five (5) days of the filing thereof with the Securities and Exchange
Commission;

              (g)  promptly upon receipt of notice thereof, a report of any

              (h)  such budgets, sales projections, operating plans or other
financial information as Bank may reasonably request from time to time.

         Bank shall have a right from time to time hereafter to audit and
examine Borrower's Accounts and Inventory at Borrower's expense, provided that
such audits will be conducted no more often than every three months unless an
Event of Default has occurred and is continuing.

         4    INVENTORY; RETURNS.  Borrower shall keep all Inventory in good
and marketable condition, free from all material defects.  Returns and
allowances, if any, as between Borrower and its account debtors shall be on the
same basis and in accordance with the usual customary practices of Borrower, as
they exist at the time of the execution and delivery of this Agreement. 
Borrower shall promptly notify Bank of all returns and recoveries and of all

of the Collateral in amounts and of a type that are customary to businesses
similar to Borrower's.

              (b)  All such policies of insurance shall be in such form, with
such companies, and in such amounts as reasonably satisfactory to Bank.  All
such policies of property insurance shall contain a lender's loss payable

Bank, showing Bank as an additional loss payee thereof and all liability
insurance policies shall show the Bank as an additional insured, and shall

before canceling its policy for any reason.  Borrower shall deliver to Bank
certified copies of such policies of insurance and evidence of the payments of
all premiums therefor.  All proceeds payable under any such policy shall, at the
option of Bank, be payable to Bank to be applied on account of the Obligations.

         7    PRINCIPAL DEPOSITORY.  Borrower shall maintain its primary
banking relationship with Bank, provided, that Borrower shall be permitted to

Borrower), provide the depository bank with written notice of Bank's security
interest in the Local Deposit Account (with a copy thereof delivered to Bank)
pursuant to the Form of Notification and Acknowledgment for Pledged Deposit
attached as EXHIBIT D hereto.

its best efforts to effect an exchange, within 90 days of the Closing Date, 
of not less than $1,000,000.00 of its existing trade accounts payable for 
Common Stock at an

not do any of the following:

         1    DISPOSITIONS.  Convey, sell, lease, transfer or otherwise dispose

licenses and similar arrangements for the use of the property of Borrower or its
Subsidiaries; or (iii) Transfers of worn-out or obsolete Equipment.

         2    CHANGE IN BUSINESS.  Engage in any business, or permit any of its
Subsidiaries to engage in any business, other than the businesses currently

management or directors.  Borrower will not, without thirty (30) days prior
written notification to Bank, relocate its chief executive office.

         3    MERGERS OR ACQUISITIONS.  Merge or consolidate, or permit any of

Investment in or to any Person, or permit any of its Subsidiaries so to do,
other than Permitted Investments.

         8    TRANSACTIONS WITH AFFILIATES.  Directly or indirectly enter into
or permit to exist any material transaction with any Affiliate of Borrower
except for transactions that are in the ordinary course of Borrower's business,
upon fair and reasonable terms that are no less favorable to Borrower than would
be obtained in an arm's length transaction with a nonaffiliated Person.

Subordinated Debt, or permit any of its Subsidiaries to make any such payment,

<PAGE>

         Any one or more of the following events shall constitute an Event of
Default by Borrower under this Agreement:

         1    PAYMENT DEFAULT.  If Borrower fails to pay, when due, any of the
Obligations.

         2    COVENANT DEFAULT.

              (a)  If Borrower fails to perform any obligation under Sections
6.7, 6.8 or 6.9 or violates any of the covenants contained in Article 7 of this
Agreement, or

              (b)  If Borrower fails or neglects to perform, keep, or observe
any other material term, provision, condition, covenant, or agreement contained
in this Agreement, in any of the Loan Documents, or in any other present or
future agreement between Borrower and Bank and as to any default under such
other term, provision, condition, covenant or agreement that can be cured, has
failed to cure such default within ten (10) days after Borrower receives notice
thereof or any officer of Borrower becomes aware thereof; provided, however,
that if the 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 Advances will be required to be
made during such cure period);

         3    MATERIAL ADVERSE CHANGE.  If there occurs any change, event, or
condition which causes a Material Adverse Effect;

         4    ATTACHMENT.  If any material portion of Borrower's assets is
attached, seized, subjected to a writ or distress warrant, or is levied upon, or
comes into the possession of any trustee, receiver or person acting in a similar
capacity and such attachment, seizure, writ or distress warrant or levy has not
been removed, discharged or rescinded within ten (10) days, or if Borrower is
enjoined, restrained, or in any way prevented by court order from continuing to
conduct all or any material part of its business affairs, or if a judgment or
other claim becomes a lien or encumbrance upon any material portion of

likely to have a Material Adverse Effect;

         7    SUBORDINATED DEBT.  If Borrower makes any payment on account of

satisfaction or stay of such judgment);

         10   MISREPRESENTATIONS.  If any material misrepresentation or
material misstatement exists now or hereafter in any warranty or representation

Guaranty or in any certificate delivered to Bank in connection with the
Guaranty.

    9.   BANK'S RIGHTS AND REMEDIES

         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 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 owned premises, Borrower hereby grants Bank a
license to enter into possession of such premises and to occupy the same,
without charge, for up to one hundred twenty (120) days 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;


                                         -30-

<PAGE>

              (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 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)  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;

              (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.

         2    POWER OF ATTORNEY.  Effective only upon the occurrence and during
the continuance of an Event of Default, and for the purpose of protecting and
preserving Bank's security interest in the Collateral and the proceeds thereof,
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


                                         -31-

<PAGE>

interest, is irrevocable until all of the Obligations have been fully repaid and
performed and Bank's obligation to provide advances hereunder is terminated.

         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.

         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.

         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.

         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


                                         -32-

<PAGE>

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.

         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 on which Borrower may in any way be liable.

Clara, State of California.  BORROWER AND BANK EACH HEREBY WAIVE THEIR

                                         -33-

ACTION BASED UPON OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY OF THE
TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS,

RECOGNIZES AND AGREES THAT THE FOREGOING WAIVER CONSTITUTES A MATERIAL
INDUCEMENT FOR IT TO ENTER INTO THIS AGREEMENT.  EACH PARTY REPRESENTS AND
WARRANTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL AND THAT IT
KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION
WITH LEGAL COUNSEL.

    12.  GENERAL PROVISIONS

         1    SUCCESSORS AND ASSIGNS.  This Agreement shall bind and inure to
the benefit of the respective successors and permitted assigns of each of the
parties; PROVIDED, HOWEVER, that neither this Agreement nor any rights hereunder
may be assigned by Borrower without Bank's prior written consent, which consent
may be granted or withheld in Bank's sole discretion.  Bank shall have the right
without the consent of or notice to Borrower to sell, transfer, negotiate, or
grant participation in all or any part of, or any interest in, Bank's
obligations, rights and benefits hereunder.

         2    INDEMNIFICATION.  Borrower shall defend, indemnify and hold
harmless Bank and its officers, employees, and agents against:  (a) all
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.

         3    TIME OF ESSENCE.  Time is of the essence for the performance of
all obligations set forth in this Agreement.

         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.

         5    AMENDMENTS IN WRITING, INTEGRATION.  This Agreement cannot 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, if any, are merged into this
Agreement and the Loan Documents.


                                         -34-

<PAGE>

         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.

         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,
provided that so long as the obligations set forth in the first sentence of this
Section 12.7 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.

         8    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 and (iv) as may be required in connection with
the examination, audit or similar investigation of Bank.  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.

         9    RELEASE BY BORROWER.

              (a)  NO PRESENT CLAIMS.  Borrower acknowledges and agrees that: 
(i) Borrower has no claim or cause of action against any Released Party; (ii)
Borrower has no offset right, counterclaim, or defense of any kind against any
of the Indebtedness; and (iii) each Released Party has heretofore


                                         -35-

<PAGE>

properly performed and satisfied in a timely manner any and all of such Released
Party's obligations, if any, to Borrower.  Bank desires, and Borrower agrees, to
eliminate any possibility that any past conditions, acts, omissions, events,
circumstances, or matters would impair or otherwise adversely affect any of
Bank's rights, interests, collateral security, or remedies.  Therefore,
Borrower, on behalf of Borrower and all successors and assigns of Borrower and
any and all other parties claiming rights through Borrower, unconditionally
releases, acquits, and forever discharges each and every Released Party from: 
(1) any and all liabilities, obligations, duties, or indebtedness of any of the
Released Parties to Borrower, whether known or unknown, arising prior to the
date hereof, and (2) any and all claims, offsets, causes of action, suits, or
defenses, whether known or unknown, which Borrower might otherwise have against
any of the Released Parties on account of any condition, act, omission, event,
contract, liability, obligation, indebtedness, claim, cause of action, defense,
circumstance, or matter of any kind which existed, arose or occurred at any time
prior to the date hereof.  As further consideration for the above release,
Borrower specifically agrees, represents, and warrants that the matters released
herein are not limited to matters which are known or disclosed, and Borrower
hereby waives any and all rights and benefits which Borrower now has, or in the
future may have, conferred upon Borrower by virtue of the provisions of Section
1542 of the Civil Code of the State of California which provides as follows:

         A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
         DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF
         EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY
         AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

              (b)  WAIVER OF UNKNOWN CLAIMS.  Borrower is aware that Borrower
may later discover facts in addition to or different from those which Borrower
now knows or believes to be true with respect to the releases given herein, and
that it is nevertheless Borrower's intention to settle, release, and discharge
fully, finally, and forever all of these matters, known or unknown, suspected or
unsuspected, which previously existed, now exist, or may exist.  In furtherance
of such intention, Borrower specifically acknowledges and agrees that the
releases given in this Agreement shall be and shall remain in effect as full and
complete releases of the matters being released, notwithstanding the discovery
or existence of any such additional or different facts and that such releases
shall not be subject to termination or rescission by reason of any such
additional or different facts.

<PAGE>

              (c)  WARRANTY OF NON-ASSIGNMENT.  Borrower hereby represents and
warrants that it has not previously assigned or transferred, or purported to
assign or transfer, to any person or entity any of the claims, demands,
grievances, liabilities, debts, accounts, obligations, costs, expenses, liens,
rights, actions, or causes of action released by the terms of this Agreement.
