Interest accrues at the rate in Section 2.2(a). The Equipment Loan when
repaid may not be reborrowed.

     (c) To obtain the Equipment Advance, Borrower must deliver to Bank the
Payment/Advance Form attached as Exhibit B which must be signed by a Responsible
Officer and include a copy of the invoices for the Eligible Equipment being
financed. Bank shall credit the Equipment Advance to Borrower's deposit account.
Borrower can transfer the Equipment Advance from Borrower's account on the date
the Bank makes the Equipment Advance, if the transfer is within regular business
hours of the Bank. Bank may make the Equipment Advance under this Agreement
based on instructions from a Responsible Officer or his or her designee. Bank
may rely on any telephone notice given by a person whom Bank believes is a
Responsible Officer or designee.

2.2  INTEREST RATE: PAYMENTS.

     (a) Interest Rate. The Equipment Loan accrues interest on the outstanding
principal balance at the rate of 10 per cent per annum. After an Event of
Default, Obligations accrue interest at 5 percent above the rate effective
immediately before the Event of Default. Interest is computed on a 360-day year
for the actual number of days elapsed.

     (b) Payments. Interest and principal on the Equipment Loan is payable on
the first day of each month following the Advance under the Equipment Loan. Bank
may debit any of Borrower's deposit accounts including Account Number 501569370
for principal and interest payments or any other amounts that Borrower owes Bank
under this Agreement if the same are not paid within fifteen days of the date
when due. Bank will notify Borrower when it debits Borrower's accounts. These
debits are not a set-off. Payments received after 12:00 noon Pacific time, are
considered received at the opening of business on the next Business Day. When a
payment is due on a day that is not a Business Day, the payment is due the next
Business Day.

     (c) Pre-Payments. Borrower shall be allowed to prepay the Equipment Loan
without premium or penalty, except with respect to the Final Payment, described
in Section 2.2(d) below.

     (d) Final Payment. On the date of the final Equipment Loan Payment, or upon
prepayment of the Equipment Loan in full, Borrower will pay, in addition to the
unpaid principal and accrued interest and all other amounts due on such date
with respect to the Equipment Loan, an amount equal to the Final Payment.

2.3  AGREEMENTS REGARDING INTEREST AND OTHER CHARGES.

     Borrower and the Bank agree that the only charges imposed or to be imposed
by Bank upon Borrower for the use of money in connection with the Obligations is
and will be the interest required to be paid under the provisions of this
Agreement as well as the related provisions of the Loan Documents, the amount of
interest due and payable under this Agreement or the Loan Documents will not
exceed the maximum rate of interest allowed by applicable law and, if any
payment is made by Borrower or received by Bank in excess of such payment, such
sum shall be credited as a payment of principal. It is the express intent that
Borrower not pay and the Bank

                                       4
<PAGE>

not receive, directly or indirectly or in any manner, interest in excess of that
which may be lawfully paid under applicable law. All interest and other charges,
fees or other amounts deemed to be interest which are paid or agreed to be paid
to Bank under this Agreement or the Loan Documents shall, to the maximum extent
permitted by applicable law, be amortized, allocated and spread on a pro-rata
basis throughout the entire actual term of the Obligations. Any and all fees
payable under this Agreement are not intended, and will not be deemed to be
interest or a charge for use of money, but rather will constitute an "other
charge."

2.4  FEES. Borrower will pay to Bank:

     (a) Facility Fee. A facility fee of $5,000 for the Equipment Loan shall be
paid upon execution of this Agreement; and

     (b) Bank Expenses. All Bank Expenses incurred through and after the date of
this Agreement, are payable when due.

2.5 ADDITIONAL COSTS. If, after the date hereof, any new law or regulation
increases Bank's costs or reduces its income for any loan to a level that would
have been achieved but for such new regulation or law, Borrower will pay the
increase in cost or reduction in income or additional expense; provided,
however, that Borrower shall not be liable for any amount attributable to any
period before 180 days prior to the date Bank notifies Borrower of such
increased costs. Bank agrees that it will allocate any increased costs among its
customers similarly affected in good faith and in a manner consistent with
Bank's customary practice.

3    CONDITIONS OF LOAN

4.1 GRANT OF SECURITY INTEREST. Borrower grants Bank a continuing security
interest in all presently existing and later acquired Collateral, and the
proceeds of all Collateral, to secure all Obligations and performance of each of
Borrower's duties under the Loan Documents. Except for Permitted Liens, any
security interest will be a first priority security interest in the Collateral.

                                       5

<PAGE>

Bank may place a "hold" on any deposit account pledged as Collateral. If the
Agreement is terminated, Bank's lien and security interest in the Collateral
will continue until Borrower fully satisfies its Obligations.

4.2  RESERVED.

5    REPRESENTATIONS AND WARRANTIES

     Borrower represents and warrants as follows:

5.1 DUE ORGANIZATION AND AUTHORIZATION. Borrower is duly existing under the laws
of the state of Delaware and qualified and licensed to do business in, and in
good standing in, any state in which the conduct of its business or its
ownership of property requires that it be qualified, except where the failure to
do so could not reasonably be expected to cause a Material Adverse Change.

     The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with any of Borrower's formation documents,
nor constitute an event of default under any material agreement by which
Borrower is bound. Borrower is not in default under any agreement to which or by
which it is bound in which the default could cause a Material Adverse Change.

5.2 COLLATERAL, Borrower has good title to the Collateral, free of Liens except
Permitted Liens. All inventory is in all material respects of good and
marketable quality, free from material defects except for work in process and
inventory, which due to manufacturing yield issues, may not be free from defect.
Borrower is the sole owner of, or has adequate license rights in, the
Intellectual Property, except for non-exclusive licenses granted to its
customers in the ordinary course of business. No patent has been judged invalid
or unenforceable, in whole or in part, and no claim has been made that any
patent violates the rights of any third party, except to the extent such
invalidity, unenforceability or claim could not reasonably be expected to cause
a Material Adverse Change.

5.3 LITIGATION: Except as identified in Schedule 1, there are no actions or
proceedings pending or, to Borrower's knowledge, threatened by or against
Borrower in which an adverse decision that could cause a Material Adverse Change
is reasonably likely.

5.4 NO MATERIAL ADVERSE CHANGE IN FINANCIAL STATEMENTS. All historical
consolidated financial statements for Borrower, and any Subsidiary, delivered to
Bank fairly present, at the time the statements were created, in all material
respects Borrower's consolidated financial condition and Borrower's consolidated
results of operations as of the date thereof. There has not been any material
deterioration in Borrower's consolidated financial condition since the date of
the most recent financial statements submitted to Bank.

5.5 SOLVENCY. The fair salable value of Borrower's assets (including goodwill
minus disposition costs) exceeds the fair value of its liabilities; the Borrower
is not left with

                                       6
<PAGE>

unreasonably small capital after the transactions in this Agreement; and
Borrower is able to pay its debts (including trade debts) as they mature.

5.6 REGULATORY COMPLIANCE. Borrower is not a registered investment company, or
required to register as an investment company, or a company controlled by a
registered investment company under the Investment Company Act. Borrower is not
engaged as one of its important activities in extending credit for margin stock
(under Regulations T and U of the Federal Reserve Board of Governors). Borrower
has complied with the Federal Fair Labor Standards Act. Borrower has not
violated any laws, ordinances or rules, the violation of which could cause a
Material Adverse Change. None of Borrower's or any Subsidiary's properties or
assets has been used by Borrower or any Subsidiary or, to the best of Borrower's
knowledge, by previous Persons, in disposing, producing, storing, treating, or
transporting any hazardous substance. Borrower and each Subsidiary has timely
filed all required tax returns and paid, or made adequate provision to pay, all
taxes, except those being contested in good faith. Borrower and each Subsidiary
has obtained all consents, approvals and authorizations of, made all
declarations or filings with, and given all notices to, all government
authorities that are necessary to continue its business as currently conducted.

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

5.8 FULL DISCLOSURE. No representation, warranty or other statement of Borrower
in any certificate or written statement given to Bank contains any untrue
statement of a material fact or omits to state a material fact necessary to
make the statements contained in the certificates or statements not misleading
in any material respect.

6    AFFIRMATIVE COVENANTS

Borrower will do all of the following:

6.1 GOVERNMENT COMPLIANCE. Borrower shall maintain its and all Subsidiaries'
legal existence and good standing in its jurisdiction of formation and maintain
qualification in each jurisdiction in which the failure to so qualify is
reasonably likely to have a material adverse effect on Borrower's business or
operations. Borrower shall comply, and have each Subsidiary comply, with all
laws, ordinances and regulations to which it is subject, noncompliance with
which is reasonably likely to have a material adverse effect on Borrower's
business or operations or cause a Material Adverse Change.

6.2  FINANCIAL STATEMENTS, REPORTS, CERTIFICATES.

     (a) Borrower shall deliver to Bank: (i) as soon as available, but no later
than 30 days after the last day of each month, a company prepared consolidated
balance sheet and income statement covering Borrower's consolidated operations
during the period, in a form reasonably acceptable to Bank and certified by a
Responsible Officer; (ii) as soon as available, but no later than 120 days after
the last day of Borrower's fiscal year, audited consolidated financial
statements prepared under GAAP, consistently applied, together with an
unqualified opinion on

                                       7
<PAGE>

the financial statements from an independent certified public accounting firm
reasonably acceptable to Bank; (iii) within 5 days of filing, copies of all
statements, reports and notices filed or made available to any government agency
or to any holders of Subordinated Debt; (iv) a prompt report of any legal
actions pending or threatened against Borrower or any Subsidiary that could
result in damages or costs to Borrower or any Subsidiary of $150,000 or more;
(v) prompt notice of any material change in the composition of the Intellectual
Property, including any subsequent ownership right of Borrower in or to any
Copyright, Patent or Trademark not shown in any intellectual property security
agreement between Borrower and Bank or knowledge of an event that materially
adversely affects the value of the Intellectual Property; and (vi) an annual
budget approved by the Board and will provide as soon as available, but no later
than 30 days after requested, sales projections, operating plans or other
financial information requested by the Bank, which request, absent an Event of
Default, shall not occur more than once per calendar year.

     (b) Within 30 days after the last day of each month, Borrower will deliver
to Bank with the monthly financial statements a Compliance Certificate signed by
a Responsible Officer in the form of Exhibit C.

     (c) Bank has the right to audit the Collateral once per calendar year
absent an Event of Default, and to require certification of the existence of the
Collateral, once per calendar year absent an Event of Default, at Borrower's
expense.

6.3 INVENTORY; RETURNS. Borrower will keep all Inventory in good and marketable
condition, free from material defects. Returns and allowances between Borrower
and its account debtors will follow Borrower's practices as they exist at
execution of the Agreement. Borrower must promptly notify Bank of all returns,
recoveries, disputes and claims that involve more than $50,000 in any one
instance.

6.4 TAXES. Except for taxes being contested in good faith and for which Borrower
has made appropriate reserves, Borrower shall make timely payment of all
material federal, state, and local taxes or assessments and will deliver to
Bank, on demand, appropriate certificates attesting to the payment.

6.5 INSURANCE. Borrower will keep its business and the Collateral insured for
risks and in amounts, as is typical in Borrower's business. Insurance policies
will be in a form, with companies, and in amounts that are satisfactory to Bank
in Bank's reasonable discretion. All property policies will have a lender's loss
payable endorsement showing Bank as an additional loss payee and all liability
policies will show the Bank as an additional insured and provide that the
insurer must give Bank at least 20 days notice before canceling its policy. At
Bank's request, Borrower will deliver certified copies of policies and evidence
of all premium payments. So long as no Event of Default has occurred and is
continuing, Borrower shall have the option of applying the proceeds of any
casualty policy to the replacement or repair of destroyed or damaged property;
provided that, after the occurrence and during the continuance of an Event of
Default, all proceeds payable under any such casualty policy shall, at the
option of Bank, be payable to Bank on account of the Obligations.

                                       8
<PAGE>

6.6 BANK ACCOUNTS. Borrower shall maintain with the Bank (i) its primary
operating account (the "SVB Account"); and (ii) the majority of all excess cash
and investment balances, which the Borrower has the sole right to direct the
Bank as to how the monies are to be invested; provided, however, that the
Borrower shall not be required to terminate any existing fixed maturity
instrument with a third party to comply with this requirement. Borrower's
investment control includes, but is not limited to, the type of instrument
(commercial paper), amount and timing. The Bank agrees that any management or
transaction fees will be comparable to those which it charges to other companies
to which it provides similar services.

6.7 FURTHER ASSURANCES. Borrower shall execute any further instruments and take
further action as Bank reasonably requests to perfect or continue Bank's
security interest in the Collateral or to effect the purposes of this Agreement.

6.8  FINANCIAL COVENANTS.

25% of the operating budget approved by the Borrower's Board of Directors and
reviewed by Bank.

offering on or before January 1, 2003.

ordinary course of business; (ii) of non-exclusive licenses and similar
arrangements for the use of the property of Borrower or its Subsidiaries in the
ordinary course of business; or (iii) of worn-out or obsolete Equipment.

                                       9
<PAGE>

offering or to venture capital investors approved by Bank, which approval shall

9.1 RIGHTS AND REMEDIES. When an Event of Default occurs and continues Bank
may, without notice or demand, do any or all of the following:

     (a) Declare all Obligations immediately due and payable (but if an Event of
Default described in Section 8.5 occurs all Obligations are immediately due and
payable without any action by Bank);

     (b) Stop advancing money or extending credit for Borrower's benefit 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, on terms and in any order that Bank considers advisable;

     (d) Make any payments and do any acts it considers necessary or reasonable
to protect its security interest in the Collateral. Borrower will assemble the
Collateral if Bank requests and make it available as Bank designates. Bank may
enter premises where the Collateral is located, take and maintain possession of
any part of the Collateral, and pay, purchase, contest, or compromise any Lien
which appears to be prior or superior to its security interest and pay all
expenses incurred. Borrower grants Bank a license to enter and occupy any of
its premises, without charge, to exercise any of Bank's rights or remedies; Not
withstanding anything set forth herein to the contrary, Bank shall pay all
expenses incurred for damage caused by Bank or any of its agents to any of its
premises which are outside of ordinary wear and tear;

     (e) Apply to the Obligations any (i) balances and deposits of Borrower, or
(ii) any amount held by Bank owing to or for the credit or the account of
Borrower;

     (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for
sale, advertise for sale, and sell the Collateral; and

                                       12

<PAGE>

     (g) Exercise all rights and remedies accorded to the Bank under the Uniform
Commercial Code;

provided, however, that nothing in this Section 9.1 shall give the Bank any
right in any Collateral beyond the ownership rights possessed by the Borrower or
the right to take any action on behalf of the Borrower in breach of the
Borrower's obligations to third parties.

9.2 POWER OF ATTORNEY. When an Event of Default occurs and continues, Borrower
irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower's name
on any checks or other forms of payment or security; (ii) sign Borrower's name
on any invoice or bill of lading for any Account or drafts against account
debtors, (iii) make, settle, and adjust all claims under Borrower's insurance
policies; (iv) settle and adjust disputes and claims about the Accounts directly
with account debtors, for amounts and on terms Bank determines reasonable; and
(v) transfer the Collateral into the name of Bank or a third party as permitted
under the Uniform Commercial Code. Bank may exercise the power of attorney to
sign. Borrower's name on any documents necessary to perfect or continue the
perfection of any security interest in the Collateral regardless of whether an
Event of Default has occurred. Bank's appointment as Borrower's attorney in
fact, and all of Bank's rights and powers, coupled with an interest, are
irrevocable until all Obligations have been fully repaid and performed and
Bank's obligation to provide Credit Extensions terminates.

9.3 ACCOUNTS COLLECTION. When an Event of Default occurs and continues, Bank may
notify any Person owing Borrower money of Bank's security interest in the funds
and verify the amount of the Account. In such case, Borrower must collect all
payments in trust for Bank and, if requested by Bank, immediately deliver the
payments to Bank in the form received from the account debtor, with proper
endorsements for deposit.

9.4 BANK EXPENSES. If Borrower fails to pay any amount or furnish any required
proof of payment to third persons, Bank may make all or part of the payment or
obtain insurance policies required in Section 6.5, and take any action under the
policies Bank reasonably deems prudent. Any amounts paid by Bank are Bank
Expenses and immediately due and payable, bearing interest at the then
applicable rate and secured by the Collateral. No payments by Bank are deemed an
agreement to make similar payments in the future or Bank's waiver of any Event
of Default.

9.5 BANK'S LIABILITY FOR COLLATERAL. If Bank complies with reasonable banking
practices and the Uniform Commercial Code, Bank shall have no liability or
responsibility for: (a) the safekeeping of the Collateral; (b) any loss or
damage to the Collateral; (c) any diminution in the value of the Collateral; or
(d) any act or default of any carrier, warehouseman, bailee, or other person.
Borrower bears all risk of loss, damage or destruction of the Collateral.

9.6 REMEDIES CUMULATIVE. Bank's rights and remedies under this Agreement, the
Loan Documents, and all other agreements are cumulative. Bank has all rights and
remedies provided under the Uniform Commercial Code, by law, or in equity.
Bank's exercise of one right or remedy is not an election, and Bank's waiver of
any Event of Default is not a continuing waiver.

                                       13

<PAGE>

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

9.7 DEMAND WAIVER. Borrower waives demand, notice of default or dishonor, notice
of payment and nonpayment, nonpayment at maturity, release, compromise,
settlement, extension, or renewal of accounts, documents, instruments, chattel
paper, and guarantees held by Bank on which Borrower is liable. .

as expressly modified pursuant to this Loan Modification Agreement, the terms of
the Existing Loan Documents remain unchanged and in full force and effect.
Bank's agreement to modifications to the existing Indebtedness pursuant to
this Loan Modification Agreement in no way shall obligate Bank to make any
future modifications to the Indebtedness. Nothing in this Loan Modification
Agreement shall constitute a satisfaction of the Indebtedness. It is the
intention of Bank and Borrower to retain as liable parties all makers and
endorsers of Existing Loan Documents, unless the party is expressly released by
Bank in writing. The terms of this paragraph apply not only to this Loan
Modification Agreement, but also to all subsequent loan modification agreements.

9. CONDITIONS. The effectiveness of this Loan Modification Agreement is
conditioned upon (i) execution by Borrower of this Loan Modification Agreement;
and (ii) payment by Borrower of all fees and expenses required under this
Agreement.
