deliver physical possession of such Negotiable Collateral to the Lender.
2.4 Collection of Accounts, General Intangibles and Negotiable Collateral.

rights of the holders of the Prior Liens, (a) notify customers or any Account
Debtors of Borrower that the Accounts, General Intangibles or Negotiable
Collateral have been assigned to the Lender (if applicable) or that the Lender
has a security interest therein; (b) collect the Accounts, General Intangibles
and Negotiable Collateral directly and charge the collection costs and expenses
to the account of the Borrower and treat the same as a Loan hereunder; (c)
prepare for license or sale, advertise for license or sale, and license or sell
(in the manner provided for herein) the Collateral and the Lender are hereby
granted a license or other right, solely pursuant to the provisions of this

Lender's exercise of its rights under this Section 2.4, Borrower's rights under
all Collateral shall inure to the Lender's benefit; and (d) license or 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 the Lender determine is commercially
reasonable, and apply any proceeds to the Loan obligations in whatever manner or
order the Lender deem appropriate. The Lender may disclaim any warranties in
connection therewith. 2.5 Delivery of Additional Documentation Required. At any
time upon the request of the Lender, Borrower shall at its sole expense execute
and deliver to the Lender all financing statements, continuation financing
statements, fixture filings, security agreements, pledges, assignments, control
agreements, endorsements of certificates of title, applications for title,
affidavits, reports, notices, schedules of accounts, letters of authority and
all other documents that the Lender reasonably may request, in form satisfactory
to the Lender, to perfect and continue perfected the Lender's security interest
in the Collateral, and in order to fully consummate all of the transactions
contemplated hereby.
2.6 Power of Attorney. Borrower hereby irrevocably makes, constitutes and
appoints the Lender (and any of the Lender's officers, employees or agents
designated by the Lender) as Borrower's true and lawful attorney in fact, with
power to (a) if Borrower refuses to, or fails timely to execute and deliver any
of the documents described in Section 2.5, sign the name of Borrower to any of

Borrower's policies of insurance and make all determinations and decisions with
respect to such policies of insurance and (vi) settle and adjust disputes and
claims in respect of the Accounts directly with Account Debtors, for amounts and

interest, is irrevocable until all of the Obligations have been fully paid and
performed and the Lender's obligations to extend credit under the Note have

7. RIGHT TO CURE.

         In the Event of Default, so long as such Event of Default is
continuing, subject to the rights of the holders of the Prior Liens, the Lender,
in their discretion, pay any amount or do any act required of Borrower hereunder
in order to preserve, protect, maintain or enforce the Obligations, the
Collateral or the Lender's liens therein, and which Borrower fails to pay or do,
including payment of any judgment against Borrower, any insurance premium, any
warehouse charge, any finishing or processing charge, any landlord's or bailee's
claim, and any other lien upon or with respect to the Collateral. All payments
that the Lender make under this Section 7 and all out-of-pocket costs and
expenses that the Lender pay or incur in connection with any action taken by it
hereunder shall be charged to Borrower. Any payment made or other action taken
by the Lender under this Section 7 shall be without prejudice to any right to
assert the occurrence of an Event of Default hereunder and to proceed thereafter
as herein provided.
8. LENDER'S RIGHTS, DUTIES AND LIABILITIES.
8.1 No Impairment of Obligations. Borrower assumes all responsibility and
liability arising from or relating to the use, license, sale or other
disposition of the Collateral. The Obligations shall not be affected by any
failure of the Lender to take any steps to perfect the Lender's liens or to
collect or realize upon the Collateral, nor shall loss of or damage to the
Collateral release Borrower from any of the Obligations. 8.2 Borrower Remains
Liable. Anything herein to the contrary notwithstanding, Borrower shall remain
liable under each of its contracts and each of its licenses to observe and
perform all the conditions and obligations to be observed and performed by it
thereunder. The Lender shall not have any obligation or liability under any
contract or license by reason of or arising out of this Agreement or the
granting herein of a lien thereon or the receipt by the Lender of any payment
relating to any contract or license pursuant hereto. The Lender shall not be
required or obligated in any manner to perform or fulfill any of the obligations
of Borrower under or pursuant to any contract or license, or to make any
payment, or to make any inquiry as to the nature or the sufficiency of any
payment received by it or the sufficiency of any performance by any party under
any contract or license, or to present or file any claims, or to take any action
to collect or enforce any performance or the payment of any amounts which may
have been assigned to it or to which it may be entitled at any time or times. 9.
INDEMNIFICATION.

         In any suit, proceeding or action brought by the Lender relating to the
Note, this Agreement, any related documents, or Collateral for any sum owing
with respect thereto or to enforce any rights or claims with respect thereto,
Borrower will save, indemnify and keep the Lender harmless from and against all
expense (including reasonable attorneys' fees and expenses), loss or damage
suffered by reason of any defense, setoff, counterclaim, recoupment or reduction
of liability whatsoever of the Account Debtor or other individual or entity
obligated on the Collateral, arising out of a breach by Borrower of any
obligation thereunder or arising out of any other agreement, indebtedness or
liability at any time owing to, or in favor of, such obligor or its successors
from Borrower, except in the case of the Lender, to the extent such expense,
loss, or damage is attributable solely to the gross negligence or willful
misconduct of the Lender as finally determined by a court of competent
jurisdiction. All such obligations of Borrower shall be and remain enforceable
against and only against Borrower and shall not be enforceable against the
Lender.
10.      MISCELLANEOUS.
10.1 Additional Acts. Borrower shall, upon request, execute and deliver such
further instruments and documents and do such further acts and things as may be
reasonably required to provide to the Lender the evidence of and security for
the Obligations as well as the perfection of the Lender's security interest in
the Collateral. 10.2 Amendment: Waiver; Approval. This Agreement shall not be
amended, modified or supplemented without the written agreement of Borrower and
the Lender at the time of such amendment, modification or supplement. No waiver
of any provision of this Agreement shall be effective unless set forth in
writing signed by the party making such waiver, and any such waiver shall be
effective only to the extent therein set forth. Failure by the Lender to insist
upon full and prompt performance of any provisions of this Agreement, or to take
action upon the occurrence of any Event of Default, shall not constitute a
waiver of any rights of the Lender, and the Lender may at any time thereafter
exercise all available rights and remedies with respect to such Event of
Default. Receipt by the Lender of any instrument or document shall not
constitute or be deemed to be an approval thereof. 10.3 Entire Agreement. This
Agreement, the Note and related documents constitute the entire agreement and
understanding among the Borrower and the Lender, and supersede any prior
agreement and understanding relating to the subject matter of this Agreement;
provided, however, that notwithstanding the foregoing, this Agreement shall
supersede any previous security agreement, or security interest or pledge, given
by Borrower to secure any or all of the Obligations.
10.4 Notice. Any notice which any party hereto gives to any other party
hereunder shall be in accordance with the provisions of the Note relating
thereto. 10.5 Benefit; Assignment. The rights, powers and remedies of the Lender
and Borrower under this Agreement shall inure to their respective benefits and
to the benefit of their respective successors and permitted assigns. The
obligations of Borrower under this Agreement may not be assigned and any
purported assignment by Borrower shall be null and void without prior written
approval of Lender. The rights of Lender under this Agreement may be assigned
within the sole and absolute discretion of Lender without consent of or prior
notice to Borrower. 10.6 Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of California, as applied to
agreements among residents made and to be performed entirely within the State of
California. By execution and delivery of this Agreement, the parties agree and
accept that any legal action or proceeding brought with respect to this
Agreement shall be brought in the State or United States District Court of
appropriate jurisdiction in and for the County of Santa Clara, State of
California, and the parties expressly waive any objection to personal
jurisdiction, venue or forum non conveniens 10.7 Headings. The titles and
headings of the articles, sections and paragraphs of this Agreement have been
inserted as a matter of convenience of reference only and shall not control or
affect the meaning or construction of any of the terms or provisions of this
Agreement.
10.8 No Partnership or Joint Venture. The Lender, by executing and performing
this Agreement (or any of the loan documents), shall not become a partner or
joint venturer with Borrower or any of its respective associates or affiliates
and all inspections herein provided for are for the sole benefit of the Lender.
10.9 Time is of the Essence. Time is of the essence for the payment of all
amounts due the Lender under the loan documents and performance and observance
by Borrower of each covenant, agreement, provision and term of the loan
documents.
10.10 Invalid Provisions. In the event any one or more of the provisions
contained in this Agreement or in any of the other loan documents shall for any
reason be held to be invalid, illegal or unenforceable in any respect by a court
of competent jurisdiction, such invalidity, illegality or unenforceability shall
not affect any other provision of this Agreement or any other Loan Document, and
this Agreement and the other Loan Document shall be construed as if such
invalid, illegal or unenforceable provision had never been in the Loan
documents. 10.11 Acts Prohibited Under Law. Notwithstanding anything herein
contained to the contrary, the Lender will not be required to make any
disbursement or perform any other act under this Agreement if, as a result
thereof, the Lender will violate any law, statute, ordinance, rule, regulation
or judicial decision applicable thereto. The Lender shall use their reasonable
efforts to promptly notify Borrower of the Lender's inability to make such
disbursement or perform such act due to such violation.
10.12 Counterparts. This Agreement and the other Loan documents may be executed
in counterparts, and all said counterparts when taken together shall constitute
one and the same Agreement. 10.13 No Third Party Beneficiary. This Agreement and
the other Loan documents are only for the benefit of the parties hereto and
thereto and their permitted successors and assigns. No other person or entity
shall be entitled to rely on any matter set forth herein or therein or shall
gain any rights herein whether by subrogation or otherwise without the prior
written consent of such parties.
