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

                                      -8-

<PAGE>


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, 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.

          2.4 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
Eleven Thousand Two Hundred Fifty Dollars ($11,250), receipt of which is
acknowledged, which shall be nonrefundable; and

              (b) 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 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 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.

                                      -9-

          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.

     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 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. Except as set forth in the
Schedule, such security interest constitutes a valid, first

                                      -10-

<PAGE>


priority security interest in the presently existing Collateral, and will
constitute a valid, first priority security interest in Collateral acquired
after the date hereof.

          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 the
perfection of 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 but no more than twice a year (unless an
Event of Default has occurred and is continuing), 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, provided that Borrower shall be
obligated to reimburse Bank for only one (1) such audit per year unless an Event
of Default has occurred and is continuing.

          4.4 Pledge of Collateral. Borrower hereby pledges, assigns and grants
to Bank a security interest in all the Shares, together with all proceeds and
substitutions thereof, all cash, stock and other moneys and property paid

as security for the performance of the Obligations. The certificate or
certificates for the Shares, as relevant, will be delivered to Bank by Borrower.
To the extent required by the terms and conditions governing the Shares,
Borrower shall cause the books of each entity whose Shares are part of the
Collateral and any transfer agent to reflect the pledge of the Shares. Upon the
occurrence of an Event of Default hereunder, Bank may effect the transfer of any
securities included in the Collateral into the name of Bank and cause new
certificates representing such securities to be issued in the name of Bank or
its transferee. Borrower will execute and deliver such documents, and take or

continue the perfection of Bank's security interest in the Collateral. Unless an
Event of Default shall have occurred and be continuing, Borrower shall be
entitled to exercise any voting rights with respect to the Collateral and to
give consents, waivers and ratifications in respect thereof, provided that no
vote shall be cast or consent, waiver or ratification given or action taken
which would be inconsistent with any of the terms of this Agreement or which
would constitute or create any violation of any of such terms. All such rights
to vote and give consents, waivers and ratifications shall terminate upon the
occurrence and continuance of an Event of Default.

     5.   REPRESENTATIONS AND WARRANTIES.
          ------------------------------

          Borrower represents and warrants as follows:

          5.1 Due Organization and Qualification. Borrower and each Subsidiary
is a corporation duly existing under the laws of its state of incorporation and
qualified and licensed to do business in any state in which the conduct of its
business or its ownership of property requires that it be so qualified, the
failure of which to qualify is reasonably likely to have a Material Adverse
Effect.

          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 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 is not in default
under any material agreement to which it is a party or by which it is bound.

          5.3 No Prior Encumbrances. Borrower has good and marketable title to

by Borrower to its customers in the ordinary course of business. Each of the
Patents is valid and enforceable, and no part of the Intellectual Property
Collateral has been judged invalid or unenforceable, in whole or in part, and no
claim has been made that any part of the Intellectual Property Collateral
violates the rights of any third party. Except as set forth in the Schedule,
Borrower's rights as a licensee of intellectual property do not give rise to
more than five percent (5%) of its gross revenue in any given month, including
without limitation revenue derived from the sale, licensing, rendering or
disposition of any product or service. Except as set forth in the Schedule,
Borrower is not a party to, or bound by, any material agreement that restricts

respects Borrower's financial condition as of the date thereof and Borrower's

all consents, approvals and authorizations of, made all declarations or filings
with, and given all notices to, all governmental authorities that are necessary

maintained or invested with a Person other than Bank or as permitted by Section
6.7 or Section 7.7 hereof.

fact necessary in order to make the statements contained in such certificates or
statements not materially misleading.

          5.18 Shares. Borrower has full power and authority to create a first
lien on the Shares and no disability or contractual obligation exists that would
prohibit Borrower from pledging the Shares pursuant to this Agreement. Except as
disclosed in the Schedule, to Borrower's knowledge there are no subscriptions,
warrants, rights of first refusal or other restrictions on, or options
exercisable with respect to the Shares. The Shares have been and will be duly
authorized and validly issued, and are fully paid and non-assessable. To
Borrower's knowledge, the Shares are not the subject of any present or
threatened suit, action, arbitration, administrative or other proceeding, and
Borrower knows of no reasonable grounds for the institution of any such
proceedings.

rendering of such service to any third party, and prior to Borrower's use of
such product (including without limitation major revisions or additions to the
intellectual property rights listed on such Exhibits A, B and C); which, in the

confirm compliance with this Section, provided such audit may not occur more
often than twice per year, unless an Event of Default has occurred and is
continuing. Bank shall have the right, but not the obligation, to take, at

reasonable costs and reasonable expenses incurred in the reasonable exercise of
its rights under this Section.

     8.   EVENTS OF DEFAULT.
          -----------------

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

          8.1  Payment Default. If Borrower fails to pay, when due, any of the
Obligations;

          8.2  Covenant Default. If Borrower fails to perform any obligation
under Article 6 or violates any of the covenants contained in Article 7 of this
Agreement, or 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 Credit Extensions will be required to be made
during such cure period);

          8.3  Material Adverse Effect. If there occurs any circumstance or
circumstances that is reasonably likely to have a Material Adverse Effect;

          8.4  Attachment. If any portion of Borrower's assets is attached,

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

                                      -17-

<PAGE>


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 Borrower's assets, or if a notice of 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
against Borrower and is not dismissed or stayed within thirty (30) days
(provided that no Credit Extensions will be made prior to the dismissal of such
Insolvency Proceeding);

          8.6 Other Agreements. If there is a default or other failure to
perform in any agreement to which Borrower is a party or by which it is bound

Extensions will be required to be made prior to the satisfaction or stay of such
judgment); or

          8.9 Misrepresentations. If any material misrepresentation or material
misstatement exists now or hereafter in any warranty or representation set forth
herein or in any certificate delivered to Bank by any Responsible Officer
pursuant to this Agreement or to induce Bank to enter into this Agreement or any
other Loan Document.

     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 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) 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

                                      -18-

<PAGE>


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) 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;

               (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) 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
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) dispose of any Collateral; (e) make, settle, and adjust all claims
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; (g)
to file, in its sole discretion, one or more financing or continuation
statements and amendments thereto, relative to any of the Collateral; and (h) to
transfer the Intellectual Property Collateral into the name of Bank or a third
party to the extent permitted under the California Uniform Commercial Code;
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, any intellectual property security agreement entered into between
Borrower and Bank without first obtaining Borrower's approval of or signature to
such modification by amending Exhibits A, B, and C, thereof, as appropriate, to
include reference to any right, title or interest in any Copyrights, Patents or
Trademarks acquired by Borrower after the execution hereof or to delete any
reference to any right, title or interest in any Copyrights, Patents or
Trademarks in which Borrower no longer has or claims to have any right, title or
interest. 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 Credit Extensions hereunder is terminated.

          9.3  Accounts Collection. After the occurrence and during the
continuation of an Event of Default, or for the purposes of or related to an
accounts receivable audit, Bank may notify any Person owing funds to Borrower of
Bank's security interest in such funds and verify the amount of such Account.
After the occurrence and during the continuation of an Event of Default,
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, then Bank may do any or all

                                      -19-

<PAGE>


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 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; 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.
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.

          9.6  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.
