         THIS AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT (as amended,
restated, or otherwise modified from time to time, this "AGREEMENT"), dated as
of December 19, 2003, is by and between SILICON VALLEY BANK ("BANK"), whose
address is 3003 Tasman Drive, Santa Clara, California, 95054, and HARMONIC INC.,
a Delaware corporation ("BORROWER"), whose address is 549 Baltic Way, Sunnyvale,
California 94089, and provides the terms on which Bank will lend to Borrower and
Borrower will repay Bank. The parties hereto agree as follows:

1.       DEFINITIONS; ACCOUNTING AND OTHER TERMS

         Capitalized terms used herein shall have the meanings given to such
terms in Section 13 of this Agreement. Accounting terms not defined in this
Agreement will be construed according to GAAP. Calculations and determinations
must be made following GAAP. The term "financial statements" includes the notes
and schedules thereto. The terms "including" and "includes" always mean
"including (or includes) without limitation," in this or any other Loan
Document.

2.       LOAN AND TERMS OF PAYMENT

         2.1      PROMISE TO PAY.

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

                  2.1.1    ADVANCES.

                           (a)      Bank will make Advances not exceeding the
Committed Revolving Line minus (A) the outstanding principal balance of the
Advances minus (B) the amount of all outstanding Letters of Credit (including
drawn but unreimbursed Letters of Credit). Amounts borrowed hereunder that
remain available for borrowing under this Agreement may be repaid and reborrowed
prior to the Maturity Date.

                           (b)      To obtain an Advance, Borrower must notify
Bank by facsimile or telephone by 12:00 noon Pacific Time on the Business Day
the Advance is to be made. Borrower must promptly confirm the notification by
delivering to Bank the Loan Payment/Advance Request Form attached as Exhibit B
(the "PAYMENT/ADVANCE FORM"). Bank will credit Advances to Borrower's deposit
account. Bank may make Advances under this Agreement based on instructions from
a Responsible Officer or his or her designee or without instructions if the
Advances are necessary to meet Obligations which have become due. Bank may rely
on any telephone notice given by a person whom Bank believes is a Responsible
Officer or designee. Borrower will indemnify Bank for any loss Bank suffers due
to such reliance.

                           (c)      The Committed Revolving Line shall terminate
on the Maturity Date, and all Advances are immediately due and payable on the
Maturity Date.

<PAGE>

                  2.1.2    LETTERS OF CREDIT.

                           (a)      Bank will issue or have issued standby
Letters of Credit for Borrower's account not exceeding the amount available
under the Committed Revolving Line (each, a "LETTER OF CREDIT"). Each Letter of
Credit will have an expiry date of no later than 180 days after the Maturity
Date, but Borrower's reimbursement obligation will be secured by cash in an
amount equal to 105% of the face amount of all such Letters of Credit plus all
interest, fees, and costs due or to become due in connection therewith on terms
acceptable to Bank at any time after the Maturity Date if such Maturity Date is
not extended by Bank or if an Event of Default occurs and continues. Borrower
agrees to execute any further documentation in connection with the Letters of
Credit as Bank may reasonably request.

                           (b)      Prior to or simultaneously with the opening
of each Letter of Credit, Borrower shall pay to Bank Bank's customary fees
(subject to negotiation) in connection with the opening of a letter of credit
(the "LETTER OF CREDIT FEES"). The Letter of Credit Fees shall be paid upon the
opening of each Letter of Credit and upon each anniversary thereof, if required.
In addition, Borrower shall pay to Bank, for its own account, any and all
additional issuance, negotiation, processing, transfer or other fees to the
extent and as and when required by the provisions of any application for Letters
of Credit. All Letter of Credit Fees shall be part of the Obligations.

                           (c)      If any Letter of Credit is drawn upon, such
amount shall constitute an Advance but shall be immediately due and payable. If
such amount is not paid immediately, then the full amount thereof shall accrue
interest at the rate set forth in Section 2.4(a).

         2.2      EQUIPMENT ADVANCES.

                           (a)      Through September 18, 2004 (the "EQUIPMENT
AVAILABILITY END DATE"), Bank will make advances (each, an "EQUIPMENT ADVANCE"
and, collectively, "EQUIPMENT ADVANCES") not exceeding the Committed Equipment
Line.

                           (b)      Interest accrues from the date of each
Equipment Advance (each, an "EQUIPMENT ADVANCE FUNDING DATE") at the rate in
Section 2.4(a). Each Equipment Advance is payable in 36 equal monthly
installments of principal, plus accrued interest, beginning on the first of the
month following the Equipment Advance Funding Date for such Equipment Advance
and ending on the Equipment Maturity Date for such Equipment Advance. Equipment
Advances when repaid may not be reborrowed.

                           (c)      To obtain an Equipment Advance, Borrower
must provide notice in the form of a Payment/Advance Form to Bank (the notice is
irrevocable) by facsimile no later than 12:00 noon Pacific Time one Business Day
before the day on which the Equipment Advance is to be made. The Payment/Advance
Form must be signed by a Responsible Officer or designee and include a copy of
the invoice for the Equipment being financed.

                           (d)      The outstanding principal amount of term
loans previously advanced by Bank to Borrower pursuant to that certain Loan and
Security Agreement dated March 28, 2003, as amended by that Amendment to Loan
Documents dated July 17, 2003, as further amended by that certain Amendment to
Loan Documents dated September 26, 2003, are

                                       2.

set forth on Schedule A attached hereto (the "EXISTING EQUIPMENT DEBT"). The
Existing Equipment Debt shall, for all purposes hereof, be "Equipment Advances"
hereunder and be governed by all the terms and conditions of this Agreement,
except that the principal of said Existing Equipment Debt shall continue to be
payable in accordance with the amortization schedule set forth on Schedule A.
The Existing Equipment Debt shall be taken into account in determining the
maximum amount of Equipment Advances under Section 2.2(a).

         2.3      OVERADVANCES.

         If, at any time, Borrower's Obligations hereunder exceed the Committed
Revolving Line, Borrower shall immediately pay Bank the excess.

         2.4      INTEREST RATE, PAYMENTS.

                           (a)      ADVANCES. Advances accrue interest on the
outstanding principal balance thereof at a per annum rate equal one percentage
point (1.00%) above the Prime Rate. Equipment Advances accrue interest on the
outstanding principal balance thereof at a per annum rate equal to one and
one-half percentage points (1.50%) above the Prime Rate. After an Event of
Default has occurred, Obligations shall accrue interest at a rate per annum
equal to two percent (2%) above the rate effective immediately before the Event
of Default. The interest rate increases or decreases when the Prime Rate
changes. Interest is computed on a 360 day year for the actual number of days
elapsed.

                           (b)      INTEREST RATE REDUCTION. If Borrower
maintains the revenue guidelines for each time period set forth below, and
provided no Event of Default has occurred and is continuing, then the interest
rate set forth in Section 2.4(a) above with respect to the Advances and the
Equipment Advances shall be reduced by one percentage point (1.00%) for the
three months following each such period of compliance, but, in any event, shall
not be less than the Prime Rate.

                           (c)      PAYMENTS. Interest due on the Advances and
Equipment Advances is payable on the first of each month. Bank may debit any of
Borrower's deposit accounts, including account number 0341964970, for principal
and interest payments owing or any amounts Borrower owes Bank. Bank will notify
Borrower when it debits Borrower's accounts. These debits are not a set-off.
Payments received after 12:00 noon Pacific Time are considered received at the
opening of business on the next Business Day. When a payment is due on a day
that is not a Business Day, the payment is due the next Business Day and
additional fees or interest accrue.

         2.5      FEES.

                  Borrower will pay:

                           (a)      LOAN FEE. Fully earned, non-refundable loan
fees in the amount of $25,000 for the Committed Revolving Line and in the amount
of $5,111.50 for the Committed Equipment Line are due on or before the Closing
Date. Borrower shall receive a one-time credit in the amount of $21,875 toward
payment of the Committed Revolving Line fee. If, at any time, Borrower fails to
maintain a minimum aggregate amount of $25,000,000 of unrestricted funds on
deposit for 10 consecutive Business Days with SVB Asset Management and/or SVB
Securities, Borrower shall pay an additional $25,000 fee for the Committed
Revolving Line and an additional $5,111.50 fee for the Committed Equipment Line.

                           (b)      BANK EXPENSES. All Bank Expenses (including
reasonable attorneys' fees and expenses) incurred through the date of this
Agreement are payable upon demand, and Bank Expenses incurred after the date of

3.       CONDITIONS OF LOANS

         3.1      CONDITIONS PRECEDENT TO INITIAL CREDIT EXTENSION.

         Bank's obligation to make the initial Credit Extension is subject to
the condition precedent that it receive the agreements, documents, and fees it
requires.

         3.2      CONDITIONS PRECEDENT TO ALL CREDIT EXTENSIONS.

         Bank's obligation to make each Credit Extension, including the initial
Credit Extension, is subject to the following:

                           (a)      timely receipt of any Payment/Advance Form;
and

                           (b)      the representations and warranties in
Section 5 must be materially true on the date of the Payment/Advance Form and on
the effective date of each Advance and no Event of Default may have occurred and
be continuing, or result from such Advance. Each Credit Extension is Borrower's
representation and warranty on that date that the representations and warranties
of Section 5 remain true in all material respects; provided, however, that those
representations and warranties expressly referring to another date shall be true
in all material respects as of such date only.

4.       CREATION OF SECURITY INTEREST

         4.1      GRANT OF SECURITY INTEREST.

         Borrower grants Bank a continuing security interest in all presently
existing and later acquired Collateral to secure all Obligations and performance
of each of Borrower's duties under the Loan Documents. Any security interest
will be a first priority security interest in the Collateral. If this Agreement
is terminated, Bank's lien and security interest in the Collateral

                                       4.

will continue until Borrower fully satisfies its Obligations (other than
inchoate indemnity obligations).

         4.2      AUTHORIZATION TO FILE; DELIVERY OF ADDITIONAL DOCUMENTATION.

         Borrower authorizes Bank to file financing statements without notice to
Borrower, with all appropriate jurisdictions, as Bank deems appropriate, in
order to perfect or protect Bank's security interest in the Collateral. Borrower
shall execute and deliver to Bank, at the request of Bank, all documents that
Bank may reasonably request, in form satisfactory to Bank, to perfect and
continue perfected Bank's security interest in the Collateral and in order to
fully consummate all of the transactions contemplated under the Loan Documents.

5.       REPRESENTATIONS AND WARRANTIES

         Borrower represents and warrants as follows:

         5.1      DUE ORGANIZATION; ORGANIZATIONAL STRUCTURE; AUTHORIZATION.

         Borrower and each Subsidiary is duly existing and in good standing in
its state of formation 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.

         Borrower has not changed its state of formation or organizational
structure or type or any organizational number assigned by its jurisdiction of
formation.

         The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with 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 reasonably be expected to cause a Material
Adverse Change.

         5.2      PLACES OF BUSINESS; LOCATION OF COLLATERAL.

         Except as set forth in the Disclosure Letter, the Equipment and
Inventory is not in the possession of any third party bailee (such as at a
warehouse, but excluding Equipment or Inventory in the possession of third
parties for demonstration or evaluation purposes, or otherwise in the ordinary
course of business consistent with past practices). In the event that Borrower,
after the date hereof, intends to store or otherwise deliver the Collateral to
such a bailee, then Borrower may amend the Disclosure Letter so long as such new
location is within the continental United States.

         5.3      COLLATERAL.

                           (a)      Borrower has rights in the Collateral and
its Intellectual Property sufficient to grant a security interest therein, free
of Liens except Permitted Liens. All of Borrower's Deposit Accounts and any
existing commercial tort claims are described on the Disclosure Letter. The
Accounts are bona fide, existing obligations, and the service or property

                                       5.
<PAGE>

has been performed or delivered to the account debtor or its agent for immediate
shipment to and unconditional acceptance by the account debtor. All Inventory is
in all material respects of good and marketable quality, free from material
defects. Borrower is the sole owner of the Intellectual Property, except for
non-exclusive and exclusive licenses granted in the ordinary course of business.
Each issued Patent owned by Borrower is valid and enforceable and no part of the
Intellectual Property has been judged invalid or unenforceable, in whole or in
part, and no claim has been made that any part of the Intellectual Property
violates the rights of any third party, except to the extent such claim could
not reasonably be expected to cause a Material Adverse Change. None of the
Equipment financed by Bank now is or will be affixed to any real property in
such a manner, or with such intent, as to become a fixture.

                           (b)      All statements made and all unpaid balances
appearing in all invoices, instruments, and other documents evidencing the
Accounts are and shall be true and correct. All such invoices, instruments, and
other documents, and all of Borrower's Books are and shall be genuine and in all
respects are what they purport to be. All sales and other transactions
underlying or giving rise to each Account shall comply in all material respects
with all applicable laws and governmental rules and regulations. To the best of
Borrower's knowledge, all signatures and endorsements on all documents,
instruments, and agreements relating to all Accounts are and shall be genuine,
and all such documents, instruments, and agreements are and shall be legally
enforceable in accordance with their terms.

         5.4      LITIGATION.

         Except as shown in the Disclosure Letter, there are no actions or
proceedings pending or, to the knowledge of Borrower's Responsible Officers,
threatened by or against Borrower or any Subsidiary in which a likely adverse
decision could reasonably be expected to cause a Material Adverse Change.

         5.5      NO MATERIAL ADVERSE CHANGE IN FINANCIAL STATEMENTS.

         All consolidated financial statements for Borrower, and any Subsidiary,
delivered to Bank fairly present in all material respects Borrower's
consolidated financial condition and Borrower's consolidated results of
operations. 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.

         5.6      TAXES.

         As of the date hereof, and except as set forth on the Disclosure
Letter, Borrower is unaware of any claims or adjustments proposed for any of
Borrower's prior tax years which could result in additional taxes becoming due
and payable by Borrower.

         5.7      SOLVENCY.

         The fair salable value of Borrower's assets (including goodwill minus
disposition costs) exceeds the fair value of its liabilities; the Borrower's
remaining assets after the transactions contemplated herein are not unreasonably
small in relation to its business; and Borrower is able to pay its debts
(including trade debts) as they mature.

                                       6.
<PAGE>

         5.8      EXISTING TERM DEBT.

         Schedule A accurately reflects the outstanding principal amount of and
the payment dates, payment amounts, and maturity dates with respect to the
Existing Equipment Debt.

         5.9      REGULATORY COMPLIANCE.

         Borrower is not an "investment company" or a company "controlled" by an
"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 in all material respects with the Federal Fair Labor Standards Act.
Borrower has not violated any laws, ordinances or rules, the violation of which
could reasonably be expected to 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
other than legally. Borrower and each Subsidiary has timely filed all required
tax returns and paid, or made adequate provision to pay, all material taxes,
except those being contested in good faith with adequate reserves under GAAP.
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, except where the failure to do so could not reasonably be
expected to cause a Material Adverse Change.

         5.10     SUBSIDIARIES.

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

         5.11     FULL DISCLOSURE.

         No written representation, warranty or other statement of Borrower in
any certificate or written statement given to Bank (taken together with all such
written certificates and written statements 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 (it
being recognized by Bank that the projections and forecasts provided by Borrower
in good faith and based upon reasonable assumptions are not viewed as facts and
that actual results during the period or periods covered by such projections and
forecasts may differ from the projected and forecasted results).

6.       AFFIRMATIVE COVENANTS

         Borrower will do all of the following for so long as Bank has an
obligation to lend, or there are outstanding Obligations:

                                       7.
<PAGE>

         6.1      GOVERNMENT COMPLIANCE.

         Subject to Section 7.3, Borrower will 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 would reasonably be expected to cause a material adverse effect on
Borrower's business or operations. Borrower will comply, and have each
Subsidiary comply, with all laws, ordinances and regulations to which it is
subject, noncompliance with which could have a material adverse effect on
Borrower's business or operations or would reasonably be expected to cause a
Material Adverse Change.

         6.2      FINANCIAL STATEMENTS, REPORTS, CERTIFICATES.

                           (a)      Borrower will deliver to Bank: (i) as soon
as available, but no later than 45 days after the last day of each quarter, a
company prepared consolidated balance sheet and income statement covering
Borrower's consolidated operations during the period certified by a Responsible
Officer and in a form acceptable to Bank; (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 opinion on the financial statements from an independent
certified public accounting firm reasonably acceptable to Bank; (iii) annual
financial projections in form and substance commensurate with those provided to
Borrower's board of directors or utilized by Borrower's executive management, in
form and substance satisfactory to Bank; (iv) within 5 days of filing, copies of
all statements, reports and notices made available to Borrower's security
holders or to any holders of Subordinated Debt and all reports on Form 10-K,
10-Q and 8-K filed with the Securities and Exchange Commission (the "SEC")
(other than those reports on Form 10-K, 10-Q or 8-K (relating to certification)
that are otherwise publicly available through the SEC's EDGAR system); (v) a
prompt report of any claim, proceeding, litigation, or investigation in the
future threatened or instituted against Borrower which would reasonably be
expected to result in damages to Borrower of $500,000 or more, exclusive of
litigation the potential liability in connection with which is fully insured
against; and (vi) budgets, sales projections, operating plans or other financial
information Bank reasonably requests.

                           (b)      Within 45 days after the last day of each
quarter, Borrower will deliver to Bank with the quarterly financial statements a
Compliance Certificate.

                           (c)      Borrower will allow Bank to audit Borrower's
Collateral at Borrower's expense, and the charge therefor shall be $750 per
person per day (or such higher amount as shall represent Bank's then current
standard charge for the same), plus reasonable out-of-pocket expenses. In the
event Borrower and Bank schedule and audit more than 10 days in advance, and
Borrower seeks to reschedule the audit with less than 10 days written notice to
Bank, then (without limiting any of Bank's rights and remedies) Borrower shall
pay Bank a cancellation fee of $1,000 plus any out-of-pocket expenses incurred
by Bank to compensate Bank for the anticipated costs and expenses of
cancellation. The results of audits will be satisfactory to Bank, and audits
will be conducted no more often than once every year unless an Event of Default
shall have occurred.

                                       8.
<PAGE>

         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 customary practices as they exist at execution of
this Agreement. Borrower must promptly notify Bank of all returns, recoveries,
disputes and claims that occur after the occurrence and during the continuance
of an Event of Default.

         6.4      COLLATERAL.

                           (a)      Borrower will give Bank at least 30 days
prior written notice before opening any additional place of business, changing
its chief executive office, or moving any of the Equipment or Inventory (but
excluding Equipment or Inventory in the possession of third parties for
documentation or evaluation purposes, or otherwise in the ordinary course of
business consistent with past practices) to a location other than Borrower's
address set forth in the preamble hereof or in the Disclosure Letter, except
that Borrower may maintain sales offices in the ordinary course of business at
which not more than a total of $10,000 fair market value of Equipment is
located.

                           (b)      In the event that Borrower shall at any time
after the date hereof have any commercial tort claims against others, which it
is asserting or intends to assert, and in which the likely recovery exceeds
$1,000,000, Borrower shall promptly notify Bank thereof in writing and provide
Bank with such information regarding the same as Bank shall request (unless
providing such information would waive Borrower's attorney-client privilege).
Such notification to Bank shall constitute a grant of a security interest in the
commercial tort claim and all proceeds thereof to Bank, and Borrower shall
execute and deliver all such documents and take all such actions as Bank shall
request in connection therewith.

         6.5      TAXES; PENSION CONTRIBUTIONS.

         Borrower will make, and cause each Subsidiary to 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.
Notwithstanding the foregoing, Borrower may defer payment of any contested
taxes, provided that Borrower (a) in good faith contests its obligations to pay
the taxes by appropriate proceedings promptly and diligently instituted and
conducted, (b) notifies Bank in writing of the commencement of, and any material
development in, any such proceedings involving more than $500,000, and (c) posts
bonds or takes other steps required to keep the contested taxes from becoming a
lien upon any of the Collateral. Borrower has paid, and shall continue to pay
all amounts necessary to fund all present and future pension, profit sharing,
and deferred compensation plans in accordance with their terms, and Borrower has
not and will not withdraw from participation in, permit partial or complete
termination of, or permit the occurrence of any other event with respect to, any
such plan which could reasonably be expected to result in any liability of
Borrower, including any liability to the Pension Benefit Guaranty Corporation or
its successors or any other governmental agency.

         6.6      INSURANCE.

         Borrower will keep its business and the Collateral insured for risks
and in amounts

standard for Borrower's industry, and as Bank may reasonably request. 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. Proceeds payable under any policy will, at
Bank's option if an Event of Default has occurred and is continuing, be payable
to Bank on account of the Obligations. Bank shall release to Borrower, so long
as no Event of Default is reasonably likely to occur as a result of such release
by Bank, insurance proceeds with respect to Equipment which proceeds shall be
utilized by Borrower for the replacement of the Equipment with respect to which
the insurance proceeds were paid. Bank may require reasonable assurance that the
insurance proceeds were utilized by Borrower for such purpose.

         6.7      FINANCIAL COVENANT.

enforceability of the Intellectual Property and promptly advise Bank in writing
of material infringements, (b) not allow any Intellectual Property material to
Borrower's business to be abandoned, forfeited or dedicated to the public
without Bank's written consent, (c) concurrently with the filing of any Patent
or Trademark with the United States Patent and Trademark Office, any Copyright
with the United States Copyright Office, or any similar office or agency in any
other country or any political subdivision thereof, by either itself or through
any agent, employee, licensee or designee, promptly inform Bank (if any such
additional Patents, Trademarks, and/or Copyrights are not otherwise disclosed in
Borrower's public filings with the SEC), and, upon request of Bank, execute and
deliver any and all agreements, instruments, documents, and papers as Bank may
request to evidence Bank's security interest in such Copyright, Patent or
Trademark, including, with respect to Trademarks, the goodwill of Borrower,
relating thereto or represented thereby.

         6.9      PAYMENT OF EXISTING TERM DEBT.

         Borrower shall pay the Existing Term Debt in accordance with the
amortization schedule set forth on Schedule A.

         6.10     USE OF PROCEEDS.

         Borrower will 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.

                                    Code.

         9.2      POWER OF ATTORNEY.

         Effective only when an Event of Default occurs and continues, Borrower
irrevocably appoints Bank as its lawful attorney to: (a) endorse Borrower's name
on any checks or other forms of payment or security; (b) sign Borrower's name on
any invoice or bill of lading for any Account or drafts against account debtors,
(c) make, settle, and adjust all claims under Borrower's insurance policies; (d)
settle and adjust disputes and claims about the Accounts directly with account
debtors, for amounts and on terms Bank determines reasonable; and (e) transfer
the Collateral into the name of Bank or a third party as the Code permits. 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
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, (a) Bank may notify any
Person owing Borrower money of Bank's security interest in the funds and verify
the amount of the Account, and (b) 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 6.6, and take any action under the
policies Bank 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 Code, it is
not liable 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

                                      15.
<PAGE>

agreements are cumulative. Bank has all rights and remedies provided under the
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.
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, notice of any default, 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.

11.      CHOICE OF LAW , VENUE AND JURY TRIAL WAIVER

         California law governs the Loan Documents without regard to principles
of conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction
of the State and Federal courts in Santa Clara County, California.
