                           LOAN AND SECURITY AGREEMENT

BORROWER:  VISEON, INC.
ADDRESS:   8700 N. STEMMONS FRWY #310
           DALLAS, TX 75247

DATE:      DECEMBER 5, 2001


THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between
SILICON VALLEY BANK, COMMERCIAL FINANCE DIVISION ("Silicon"), whose address is
3003 Tasman Drive, Santa Clara, California 95054 and the borrower(s) named above
(jointly and severally, the "Borrower"), whose chief executive office is located
at the above address ("Borrower's Address"). The Schedule to this Agreement (the
"Schedule") shall for all purposes be deemed to be a part of this Agreement, and
the same is an integral part of this Agreement. (Definitions of certain terms
used in this Agreement are set forth in Section 8 below.)



1. LOANS.

   1.1 LOANS. Silicon will make loans to Borrower (the "Loans"), in amounts
determined by Silicon in its *, up to the amounts (the "Credit
Limit") shown on the Schedule, provided no Default or Event of Default has
occurred and is continuing, and subject to deduction of any Reserves for accrued
interest and such other Reserves as Silicon deems proper from time to time.

   *GOOD-FAITH BUSINESS JUDGMENT

   1.2 INTEREST. All Loans and all other monetary Obligations shall bear
interest at the rate shown on the Schedule, except where expressly set forth to
the contrary in this Agreement. Interest shall be payable monthly, on the last
day of the month. Interest may, in Silicon's discretion, be charged to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as the other Loans. Silicon may, in its discretion, charge interest to
Borrower's Deposit Accounts maintained with Silicon. Regardless of the amount of
Obligations that may be outstanding from time to time, Borrower shall pay
Silicon minimum monthly interest during the term of this Agreement in the amount
set forth on the Schedule (the "Minimum Monthly Interest").

   1.3 OVERADVANCES. If at any time or for any reason the total of all
outstanding Loans and all other Obligations exceeds the Credit Limit (an
"Overadvance"), Borrower shall immediately pay the amount of the excess to
Silicon, without notice or demand. Without limiting Borrower's obligation to
repay to Silicon on demand the amount of any Overadvance, Borrower agrees to pay
Silicon interest on the outstanding amount of any Overadvance, on demand, at a
rate equal to the interest rate which would otherwise be applicable to the
Overadvance, plus an additional 2% per annum.

   1.4 FEES. Borrower shall pay Silicon the fee(s) shown on the Schedule, which
are in addition to all interest and other sums payable to Silicon and are not
refundable.

   1.5 LETTERS OF CREDIT. [Not Applicable]

2. SECURITY INTEREST.

   2.1 SECURITY INTEREST. To secure the payment and performance of all of the
Obligations when due, Borrower hereby grants to Silicon a security interest in
all of Borrower's interest in the following, whether now owned or hereafter
acquired, and wherever located: All Inventory, Equipment, Receivables, and
General Intangibles, including, without limitation, all of Borrower's Deposit
Accounts, and all money, and all property now or at any time in the future in
Silicon's possession (including claims and credit balances), and all proceeds
(including proceeds of any insurance policies, proceeds of proceeds and claims
against third parties), all products and all books and records related to any of
the foregoing (all of the foregoing, together with all other property in which
Silicon may now or in the future be granted a lien or security interest, is
referred to herein, collectively, as the "Collateral").

                                       -1-
<PAGE>


   3.1 CORPORATE EXISTENCE AND AUTHORITY. Borrower, if a corporation, is and
will continue to be, duly organized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation. Borrower is and will continue
to be qualified and licensed to do business in all jurisdictions in which any
failure to do so would have a material adverse effect on Borrower. The
execution, delivery and performance by Borrower of this Agreement, and all other
documents contemplated hereby (i) have been duly and validly authorized, (ii)
are enforceable against Borrower in accordance with their terms (except as
enforcement may be limited by equitable principles and by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to creditors'
rights generally), and (iii) do not violate Borrower's articles or certificate
of incorporation, or Borrower's by-laws, or any law or any material agreement or
instrument which is binding upon Borrower or its property, and (iv) do not
constitute grounds for acceleration of any material indebtedness or obligation
under any material agreement or instrument which is binding upon Borrower or its
property.

   3.2 NAME; TRADE NAMES AND STYLES. The name of Borrower set forth in the
heading to this Agreement is its correct name. Listed on the Schedule are all
prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Silicon 30 days' prior written notice before changing its
name or doing business under any other name. Borrower has complied, and will in
the future comply, with all laws relating to the conduct of business under a
fictitious business name.

   3.3 PLACE OF BUSINESS; LOCATION OF COLLATERAL. The address set forth in the
heading to this Agreement is Borrower's chief executive office. In addition,
Borrower has places of business and Collateral is located only at the locations
set forth on the Schedule. Borrower will give Silicon at least 30 days prior
written notice before opening any additional place of business, changing its
chief executive office, or moving any of the Collateral to a location other than
Borrower's Address or one of the locations set forth on the Schedule.*

   *NOTWITHSTANDING THE FOREGOING, BORROWER NEED NOT PROVIDE SUCH 30 DAY PRIOR
WRITTEN NOTICE WITH RESPECT TO DEMONSTRATION OR EVALUATION EQUIPMENT AND
INVENTORY THAT BORROWER LOCATES AT CUSTOMER SITES OR SITES OF OTHER THIRD
PARTIES, ALL IN THE ORDINARY COURSE OF BUSINESS, PROVIDED SUCH DEMONSTRATION OR
EVALUATION EQUIPMENT OR INVENTORY DOES NOT EXCEED $250,000 IN THE AGGREGATE FOR
ALL SUCH SITES COMBINED. ADDITIONALLY, SO LONG AS THIS AGREEMENT IS IN EFFECT,
OTHER THAN THE EQUIPMENT AND INVENTORY DESCRIBED IN THE PRECEDING SENTENCE,
BORROWER SHALL NOT TRANSFER ANY ASSETS OR COLLATERAL TO ANY PARENT, SUBSIDIARY
OR AFFILIATE OF BORROWER NOR SHALL BORROWER TRANSFER ANY ASSETS OR COLLATERAL TO
ANY LOCATION LOCATED OUTSIDE OF THE UNITED STATES REGARDLESS OF WHETHER OR NOT
SUCH LOCATION IS SET FORTH ON THE SCHEDULE IN EXCESS OF $50,000 PER OCCURRENCE
(BUT NOT TO EXCEED $100,000 IN THE AGGREGATE DURING THE TERM OF THIS AGREEMENT).

   3.4 TITLE TO COLLATERAL; PERMITTED LIENS. Borrower is now, and will at all
times in the future be, the sole owner of all the Collateral, except for items
of Equipment which are leased by Borrower. The Collateral now is and will remain
free and clear of any and all liens, charges, security interests, encumbrances
and adverse claims, except for Permitted Liens. Silicon now has, and will
continue to have, a first-priority perfected and enforceable security interest
in all of the Collateral, subject only to the Permitted Liens, and Borrower will
at all times defend Silicon and the Collateral against all claims of others.
None of the Collateral now is or will be affixed to any real property in such a
manner, or with such intent, as to become a fixture. Borrower is not and will
not become a lessee under any real property lease pursuant to which the lessor
may obtain any rights in any of the Collateral and no such lease now prohibits,
restrains, impairs or will prohibit, restrain or impair Borrower's right to
remove any Collateral from the leased premises. Whenever any Collateral is
located upon premises in which any third party has an interest (whether as
owner, mortgagee, beneficiary under a deed of trust, lien or otherwise),
Borrower shall, whenever requested by Silicon, use its best efforts to cause
such third party to execute and deliver to Silicon, in form acceptable to
Silicon, such waivers and subordinations as Silicon shall specify, so as to
ensure that Silicon's rights in the Collateral are, and will continue to be,
superior to the rights of any such third party. Borrower will keep in full force
and effect, and will comply with all the terms of, any lease of real property
where any of the Collateral now or in the future may be located.

   3.5 MAINTENANCE OF COLLATERAL. Borrower will maintain the Collateral in good
working condition, and Borrower will not use the Collateral for any unlawful
purpose. Borrower will immediately advise Silicon in writing of any material
loss or damage to the Collateral.

   3.6 BOOKS AND RECORDS. Borrower has maintained and will maintain at
Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

   3.7 FINANCIAL CONDITION, STATEMENTS AND REPORTS. All financial statements now
or in the future delivered to Silicon have been, and will be, prepared in
conformity with generally accepted accounting principles and now and in the
future will completely and accurately reflect the financial condition of
Borrower, at the times and for the periods therein stated. Between the last date
covered by any such statement provided to Silicon and the date hereof, there has
been no material adverse change in the financial condition or business of
Borrower. Borrower is now and will continue to be solvent.

   3.8 TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has timely
filed, and will timely file, all tax returns and reports required by foreign,
federal, state and local law, and Borrower has timely paid, and will timely pay,
all foreign, federal, state and local taxes, assessments, deposits and
contributions now or in the future owed by Borrower.* Borrower may, however,
defer payment of any contested taxes, provided that Borrower (i) in good faith
contests Borrower's obligation to pay the taxes by appropriate proceedings
promptly and diligently instituted and conducted, (ii) notifies Silicon in
writing of the commencement of, and any material development in, the
proceedings, and (iii) posts bonds or takes any other steps required to keep the
contested taxes from becoming a lien upon any of the Collateral. 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. 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 result
in any liability of Borrower, including any liability to the Pension Benefit
Guaranty Corporation or its successors or any other governmental agency.
Borrower shall, at all times, utilize the services of an outside payroll service
providing for the automatic deposit of all payroll taxes payable by Borrower.

   *BORROWER HAS ADVISED SILICON THAT IT IS IN THE PROCESS OF FILING OVERDUE VAT
RETURNS IN THE UNITED KINGDOM WITH AN ESTIMATED NET LIABILITY OF 15,000 BRITISH
POUNDS, AND THAT SUCH RETURNS ARE TO BE FILED BY JANUARY 31, 2002. BORROWER MUST
PROVIDE SILICON WITH WRITTEN EVIDENCE OF REGARDING THE ABOVE WITHIN FIVE DAYS OF
THE DATE HEREOF.

   3.9 COMPLIANCE WITH LAW. Borrower has complied, and will comply, in all
material respects, with all provisions of all foreign, federal, state and local
laws and regulations relating to Borrower, including, but not limited to, those
relating to Borrower's ownership of real or personal property, the conduct and
licensing of Borrower's business, and all environmental matters.

   3.10 LITIGATION. Except as disclosed in the Schedule, there is no claim,
suit, litigation, proceeding or investigation pending or (to best of Borrower's
knowledge) threatened by or against or affecting Borrower in any court or before
any governmental agency (or any basis therefor known to Borrower) which may
result, either separately or in the aggregate, in any material adverse change in
the financial condition or business of Borrower, or in any material impairment
in the ability of Borrower to carry on its business in substantially the same
manner as it is now being conducted. Borrower will promptly inform Silicon in
writing of any claim, proceeding, litigation or investigation in the future
threatened or instituted by or against Borrower involving any single claim of *
or more, or involving ** or more in the aggregate.

lawful business purposes. Borrower is not purchasing or carrying any "margin
stock" (as defined in Regulation U of the Board of Governors of the Federal
Reserve System) and no part of the proceeds of any Loan will be used to purchase
or carry any "margin stock" or to extend credit to others for the purpose of
purchasing or carrying any "margin stock."

4. RECEIVABLES.

   4.1 REPRESENTATIONS RELATING TO RECEIVABLES. Borrower represents and warrants
to Silicon as follows: Each Receivable with respect to which Loans are requested

created by the sale, delivery, and acceptance of goods or the rendition of
services in the ordinary course of Borrower's business, and (ii) meet the
Minimum Eligibility Requirements set forth in Section 8 below.

<PAGE>


   4.3 SCHEDULES AND DOCUMENTS RELATING TO RECEIVABLES. Borrower shall deliver
to Silicon transaction reports and loan requests, schedules and assignments of
all Receivables, and schedules of collections, all on Silicon's standard forms;
provided, however, that Borrower's failure to execute and deliver the same shall
not affect or limit Silicon's security interest and other rights in all of
Borrower's Receivables, nor shall Silicon's failure to advance or lend against a
specific Receivable affect or limit Silicon's security interest and other rights
therein. Loan requests received after 12:00 Noon will not be considered by
Silicon until the next Business Day. Together with each such schedule and
assignment, or later if requested by Silicon, Borrower shall furnish Silicon
with copies (or, at Silicon's request, originals) of all contracts, orders,
invoices, and other similar documents, and all original shipping instructions,
delivery receipts, bills of lading, and other evidence of delivery, for any
goods the sale or disposition of which gave rise to such Receivables, and
Borrower warrants the genuineness of all of the foregoing. Borrower shall also
furnish to Silicon an aged accounts receivable trial balance in such form and at
such intervals as Silicon shall request. In addition, Borrower shall deliver to
Silicon the originals of all instruments, chattel paper, security agreements,
guarantees and other documents and property evidencing or securing any
Receivables, immediately upon receipt thereof and in the same form as received,
with all necessary indorsements, all of which shall be with recourse. Borrower

after the date issued.

Receivables, unless and until a Default or an Event of Default has occurred *.
Borrower shall hold all payments on, and proceeds of, Receivables in trust for
Silicon, and Borrower shall immediately deliver all such payments and proceeds
to Silicon in their original form, duly endorsed in blank, to be applied to the
Obligations in such order as Silicon shall determine. Silicon may, in its
discretion, require that all proceeds of Collateral be deposited by Borrower
into a lockbox account, or such other "blocked account" as Silicon may specify,
pursuant to a blocked account agreement in such form as Silicon may specify.
Silicon or its designee may, at any time, notify Account Debtors that the
Receivables have been assigned to Silicon.

   *AND IS CONTINUING

Collateral shall be delivered, in kind, by Borrower to Silicon in the original
form in which received by Borrower not later than the following Business Day
after receipt by Borrower, to be applied to the Obligations in such order as
Silicon shall determine; provided that, if no Default or Event of Default has
occurred, Borrower shall not be obligated to remit to Silicon the proceeds of
the sale of worn out or obsolete equipment disposed of by Borrower in good faith
in an arm's length transaction for an aggregate purchase price of $25,000 or
less (for all such transactions in any fiscal year). Borrower agrees that it
will not commingle proceeds of Collateral with any of Borrower's other funds or
property, but will hold such proceeds separate and apart from such other funds
and property and in an express trust for Silicon. Nothing in this Section limits
the restrictions on disposition of Collateral set forth elsewhere in this
Agreement.

   4.6 DISPUTES. Borrower shall notify Silicon promptly of all disputes or
claims relating to Receivables. Borrower shall not forgive (completely or
partially), compromise or settle any Receivable for less than payment in full,
or agree to do any of the foregoing, except that Borrower may do so, provided
that: (i) Borrower does so in good faith, in a commercially reasonable manner,
in the ordinary course of business, and in arm's length transactions, which are
reported to Silicon on the regular reports provided to Silicon; (ii) no Default
or Event of Default has occurred and is continuing; and (iii) taking into
account all such discounts settlements and forgiveness, the total outstanding
Loans will not exceed the Credit Limit. Silicon may, at any time after the
occurrence of an Event of Default, settle or adjust disputes or claims directly
with Account Debtors for amounts and upon terms which Silicon considers
advisable in its reasonable credit judgment and, in all cases, Silicon shall
credit Borrower's Loan account with only the net amounts received by Silicon in
payment of any Receivables.

   4.7 RETURNS. Provided no Event of Default has occurred and is continuing, if
any Account Debtor returns any Inventory to Borrower in the ordinary course of
its business, Borrower shall promptly determine the reason for such return and
promptly issue a credit memorandum to the Account Debtor in the appropriate
amount (sending a copy to Silicon). In the event any attempted return occurs
after the occurrence of any Event of Default, Borrower shall (i) hold the
returned Inventory in trust for Silicon, (ii) segregate all returned Inventory
from all of Borrower's other property, (iii) conspicuously label the returned
Inventory as Silicon's property, and (iv) immediately notify Silicon of the
return of any Inventory, specifying the reason for such return, the location and
condition of the returned Inventory, and on Silicon's request deliver such
returned Inventory to Silicon.

   4.8 VERIFICATION. Silicon may, from time to time, verify directly with the
respective Account Debtors the validity, amount and other matters relating to
the Receivables, by means of mail, telephone or otherwise, either in the name of
Borrower or Silicon or such other name as Silicon may choose.

   4.9 NO LIABILITY. Silicon shall not under any circumstances be responsible or
liable for any shortage or discrepancy in, damage to, or loss or destruction of,
any goods, the sale or other disposition of which gives rise to a Receivable, or
for any error, act, omission, or delay of any kind occurring in the settlement,
failure to settle, collection or failure to collect any Receivable, or for
settling any Receivable in good faith for less than the full amount thereof, nor
shall Silicon be deemed to be responsible for any of Borrower's obligations
under any contract or agreement giving rise to a Receivable. Nothing herein
shall, however, relieve Silicon from liability for its own gross negligence or
willful misconduct.

5. ADDITIONAL DUTIES OF BORROWER.

   5.1 FINANCIAL AND OTHER COVENANTS. Borrower shall at all times comply with
the financial and other covenants set forth in the Schedule.

   5.2 INSURANCE. Borrower shall, at all times insure all of the tangible
personal property Collateral and carry such other business insurance, with
insurers reasonably acceptable to Silicon, in such form and amounts as Silicon
may reasonably require, and Borrower shall provide evidence of such insurance to
Silicon, so that Silicon is satisfied that such insurance is, at all times, in
full force and effect. All such insurance policies shall name Silicon as an
additional insured and loss payee, and shall contain a lenders loss payee
endorsement in form reasonably acceptable to Silicon. Upon receipt of the
proceeds of any such insurance, Silicon shall apply such proceeds in reduction
of the Obligations as Silicon shall determine in its sole discretion, except
that, provided no Default or Event of Default has occurred and is continuing,
Silicon shall release to Borrower insurance proceeds with respect to Equipment
totaling less than $100,000, which shall be utilized by Borrower for the
replacement of the Equipment with respect to which the insurance proceeds were
paid. Silicon may require reasonable assurance that the insurance proceeds so
released will be so used. If Borrower fails to provide or pay for any insurance,
Silicon may, but is not obligated to, obtain the same at Borrower's expense.
Borrower shall promptly deliver to Silicon copies of all reports made to
insurance companies.

   5.3 REPORTS. Borrower, at its expense, shall provide Silicon with the written
reports set forth in the Schedule, and such other written reports with respect

   5.4 ACCESS TO COLLATERAL, BOOKS AND RECORDS. At reasonable times, and on one
Business Day's notice, Silicon, or its agents, shall have the right to inspect
the Collateral, and the right to audit and copy Borrower's books and records.
Silicon shall take reasonable steps to keep confidential all information
obtained in any such inspection or audit, but Silicon shall have the right to
disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process. The foregoing
inspections and audits shall be at Borrower's expense and the charge therefor
shall be $650 per person per day (or such higher amount as shall represent
Silicon's then current standard charge for the same), plus reasonable out of
pocket expenses. Borrower will not enter into any agreement with any accounting
firm, service bureau or third party to store Borrower's books or records at any
location other than Borrower's Address, without first obtaining Silicon's
written consent, which may be conditioned upon such accounting firm, service
bureau or other third party agreeing to give Silicon the same rights with
respect to access to books and records and related rights as Silicon has under
this Loan Agreement. Borrower waives the benefit of any accountant-client
privilege or other evidentiary privilege precluding or limiting the disclosure,
divulgence or delivery of any of its books and records (except that Borrower
does not waive any attorney-client privilege).

   5.5 NEGATIVE COVENANTS. Except as may be permitted in the Schedule, Borrower
shall not, without Silicon's prior written consent, do any of the following: (i)
merge or consolidate with another corporation or entity; (ii) acquire any
assets, except in the ordinary course of business; (iii) enter into any other
transaction outside the ordinary course of business; (iv) sell or transfer any
Collateral, except for the sale of finished Inventory in the ordinary course of
Borrower's business, * and except for the sale of obsolete or unneeded Equipment

otherwise become liable with respect to the obligations of another party or
entity; (x) pay or declare any dividends on Borrower's stock (except for
dividends payable solely in stock of Borrower); (xi) redeem, retire, purchase or
otherwise acquire, directly or indirectly, any of Borrower's stock; (xii) make
any change in Borrower's capital structure which would have a material adverse
effect on Borrower or on the prospect of repayment of the Obligations; or (xiii)
pay total compensation, including salaries, fees, bonuses, commissions, and all
other payments **, whether directly or indirectly, in money or otherwise, to
Borrower's executives, officers and directors (or any relative thereof) in an
amount in excess of the amount set forth on the Schedule; or (xiv) dissolve or
elect to dissolve. Transactions permitted by the foregoing provisions of this
Section are only permitted if no Default or Event of Default would occur as a
result of such transaction.

   *EXCEPT FOR DEMONSTRATION OR EVALUATION EQUIPMENT AND INVENTORY THAT BORROWER
LOCATES AT CUSTOMER SITES OR SITES OF OTHER THIRD PARTIES, ALL IN THE ORDINARY
COURSE OF BUSINESS, PROVIDED SUCH DEMONSTRATION OR EVALUATION EQUIPMENT OR

   5.6 LITIGATION COOPERATION. Should any third-party suit or proceeding be
instituted by or against Silicon with respect to any Collateral or in any manner
relating to Borrower, Borrower shall, without expense to Silicon, make available
Borrower and its officers, employees and agents and Borrower's books and
records, to the extent that Silicon may deem them reasonably necessary in order
to prosecute or defend any such suit or proceeding.

   5.7 FURTHER ASSURANCES. Borrower agrees, at its expense, on request by
Silicon, to execute all documents and take all actions, as Silicon, may deem
reasonably necessary or useful in order to perfect and maintain Silicon's
perfected security interest in the Collateral, and in order to fully consummate
the transactions contemplated by this Agreement.

6. TERM.

   6.1 MATURITY DATE. This Agreement shall continue in effect until the maturity
date set forth on the Schedule (the "Maturity Date"), subject to Section 6.3
below.

   6.2 EARLY TERMINATION. This Agreement may be terminated prior to the Maturity
Date as follows: (i) by Borrower, effective three Business Days after written
notice of termination is given to Silicon; or (ii) by Silicon at any time after
the occurrence of an Event of Default, without notice, effective immediately. If
this Agreement is terminated by Borrower or by Silicon under this Section 6.2,
Borrower shall pay to Silicon a termination fee in an amount equal to * provided
that no termination fee shall be charged if the credit facility hereunder is
replaced with a new facility from another division of Silicon Valley Bank. The
termination fee shall be due and payable on the effective date of termination
and thereafter shall bear interest at a rate equal to the highest rate
applicable to any of the Obligations.

   *ONE PERCENT (1.0%) OF THE OVERALL CREDIT LIMIT (AS DEFINED IN THE SCHEDULE),
PROVIDED THAT THE TOTAL TERMINATION FEE UNDER THIS LOAN AGREEMENT AND UNDER THE
EXIM AGREEMENT (AS DEFINED IN THE SCHEDULE) SHALL NOT EXCEED ONE PERCENT (1.0%)
OF THE OVERALL CREDIT LIMIT, AND

   6.3 PAYMENT OF OBLIGATIONS. On the Maturity Date or on any earlier effective
date of termination, Borrower shall pay and perform in full all Obligations,
whether evidenced by installment notes or otherwise, and whether or not all or
any part of such Obligations are otherwise then due and payable. Without
limiting the generality of the foregoing, if on the Maturity Date, or on any
earlier effective date of termination, there are any outstanding Letters of
Credit issued by Silicon or issued by another institution based upon an
application, guarantee, indemnity or similar agreement on the part of Silicon,
then on such date Borrower shall provide to Silicon cash collateral in an amount
equal to the face amount of all such Letters of Credit plus all interest, fees
and cost due or to become due in connection therewith, to secure all of the
Obligations relating to said Letters of Credit, pursuant to Silicon's then
standard form cash pledge agreement. Notwithstanding any termination of this
Agreement, all of Silicon's security interests in all of the Collateral and all
of the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the * of Silicon,
Silicon may, in its sole discretion, refuse to make any further Loans after
termination. No termination shall in any way affect or impair any right or
remedy of Silicon, nor shall any such termination relieve Borrower of any
Obligation to Silicon, until all of the Obligations have been paid and performed
in full. Upon payment and performance in full of all the Obligations and
termination of this Agreement, Silicon shall promptly deliver to Borrower
termination statements, requests for reconveyances and such other documents as
may be required to fully terminate Silicon's security interests.

   7.2 REMEDIES. Upon the occurrence of any Event of Default, and at any time
thereafter, Silicon, at its option, and without notice or demand of any kind
(all of which are hereby expressly waived by Borrower), may do any one or more
of the following: (a) Cease making Loans or otherwise extending credit to
Borrower under this Agreement or any other document or agreement; (b) Accelerate
and declare all or any part of the Obligations to be immediately due, payable,
and performable, notwithstanding any deferred or installment payments allowed by
any instrument evidencing or relating to any Obligation; (c) Take possession of
any or all of the Collateral wherever it may be found, and for that purpose
Borrower hereby authorizes Silicon without judicial process to enter onto any of
Borrower's premises without interference to search for, take possession of,
keep, store, or remove any of the Collateral, and remain on the premises or
cause a custodian to remain on the premises in exclusive control thereof,
without charge for so long as Silicon deems it reasonably necessary in order to
complete the enforcement of its rights under this Agreement or any other
agreement; provided, however, that should Silicon seek to take possession of any
of the Collateral by Court process, Borrower hereby irrevocably waives: (i) any
bond and any surety or security relating thereto required by any statute, court
rule or otherwise as an incident to such possession; (ii) any demand for
possession prior to the commencement of any suit or action to recover possession
thereof; and (iii) any requirement that Silicon retain possession of, and not
dispose of, any such Collateral until after trial or final judgment; (d) Require
Borrower to assemble any or all of the Collateral and make it available to
Silicon at places designated by Silicon which are reasonably convenient to
Silicon and Borrower, and to remove the Collateral to such locations as Silicon
may deem advisable; (e) Complete the processing, manufacturing or repair of any
Collateral prior to a disposition thereof and, for such purpose and for the
purpose of removal, Silicon shall have the right to use Borrower's premises,
vehicles, hoists, lifts, cranes, equipment and all other property without
charge; (f) Sell, lease or otherwise dispose of any of the Collateral, in its
condition at the time Silicon obtains possession of it or after further
manufacturing, processing or repair, at one or more public and/or private sales,
in lots or in bulk, for cash, exchange or other property, or on credit, and to
adjourn any such sale from time to time without notice other than oral
announcement at the time scheduled for sale. Silicon shall have the right to
conduct such disposition on Borrower's premises without charge, for such time or
times as Silicon deems reasonable, or on Silicon's premises, or elsewhere and
the Collateral need not be located at the place of disposition. Silicon may
directly or through any affiliated company purchase or lease any Collateral at
any such public disposition, and if permissible under applicable law, at


                                      -7-
<PAGE>


any private disposition. Any sale or other disposition of Collateral shall not
relieve Borrower of any liability Borrower may have if any Collateral is
defective as to title or physical condition or otherwise at the time of sale;
(g) Demand payment of, and collect any Receivables and General Intangibles
comprising Collateral and, in connection therewith, Borrower irrevocably
authorizes Silicon to endorse or sign Borrower's name on all collections,
receipts, instruments and other documents, to take possession of and open mail
addressed to Borrower and remove therefrom payments made with respect to any
item of the Collateral or proceeds thereof, and, in Silicon's sole discretion,
to grant extensions of time to pay, compromise claims and settle Receivables and
the like for less than face value; (h) Offset against any sums in any of
Borrower's general, special or other Deposit Accounts with Silicon; and (i)
Demand and receive possession of any of Borrower's federal and state income tax
returns and the books and records utilized in the preparation thereof or

and obligations incurred by Silicon with respect to the foregoing shall be added
to and become part of the Obligations, shall be due on demand, and shall bear
interest at a rate equal to the highest interest rate applicable to any of the
Obligations. Without limiting any of Silicon's rights and remedies, from and
after the occurrence * of any Event of Default, the interest rate applicable to
the Obligations shall be increased by an additional four percent per annum.

   *, AND DURING THE CONTINUANCE,

   7.3 STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower and Silicon
agree that a sale or other disposition (collectively, "sale") of any Collateral
which complies with the following standards will conclusively be deemed to be
commercially reasonable: (i) Notice of the sale is given to Borrower at least
seven days prior to the sale, and, in the case of a public sale, notice of the
sale is published at least seven days before the sale in a newspaper of general
circulation in the county where the sale is to be conducted; (ii) Notice of the
sale describes the collateral in general, non-specific terms; (iii) The sale is
conducted at a place designated by Silicon, with or without the Collateral being
present; (iv) The sale commences at any time between 8:00 a.m. and 6:00 p.m; (v)
Payment of the purchase price in cash or by cashier's check or wire transfer is
required; (vi) With respect to any sale of any of the Collateral, Silicon may
(but is not obligated to) direct any prospective purchaser to ascertain directly
from Borrower any and all information concerning the same. Silicon shall be free
to employ other methods of noticing and selling the Collateral, in its
discretion, if they are commercially reasonable.

   7.4 POWER OF ATTORNEY. Upon the occurrence of any Event of Default, without
limiting Silicon's other rights and remedies, Borrower grants to Silicon an
irrevocable power of attorney coupled with an interest, authorizing and
permitting Silicon (acting through any of its employees, attorneys or agents) at
any time, at its option, but without obligation, with or without notice to
Borrower, and at Borrower's expense, to do any or all of the following, in
Borrower's name or otherwise, but Silicon agrees to exercise the following
powers in a commercially reasonable manner: (a) Execute on behalf of Borrower
any documents that Silicon may, in its sole discretion, deem advisable in order
to perfect and maintain Silicon's security interest in the Collateral, or in
order to exercise a right of Borrower or Silicon, or in order to fully
consummate all the transactions contemplated under this Agreement, and all other
present and future agreements; (b) Execute on behalf of Borrower any document
exercising, transferring or assigning any option to purchase, sell or otherwise
dispose of or to lease (as lessor or lessee) any real or personal property which
is part of Silicon's Collateral or in which Silicon has an interest; (c) Execute
on behalf of Borrower, any invoices relating to any Receivable, any draft
against any Account Debtor and any notice to any Account Debtor, any proof of
claim in bankruptcy, any Notice of Lien, claim of mechanic's, materialman's or
other lien, or assignment or satisfaction of mechanic's, materialman's or other
lien; (d) Take control in any manner of any cash or non-cash items of payment or
proceeds of Collateral; endorse the name of Borrower upon any instruments, or
documents, evidence of payment or Collateral that may come into Silicon's
possession; (e) Endorse all checks and other forms of remittances received by
Silicon; (f) Pay, contest or settle any lien, charge, encumbrance, security
interest and adverse claim in or to any of the Collateral, or any judgment based

Grant extensions of time to pay, compromise claims and settle Receivables and
General Intangibles for less than face value and execute all releases and other
documents in connection therewith; (h) Pay any sums required on account of
Borrower's taxes or to secure the release of any liens therefor, or both; (i)
Settle and adjust, and give releases of, any insurance claim that relates to any
of the Collateral and obtain payment therefor; (j) Instruct any third party
having custody or control of any books or records belonging to, or relating to,
Borrower to give Silicon the same rights of access and other rights with respect
thereto as Silicon has under this Agreement; and (k) Take any action or pay any
sum required of Borrower pursuant to this Agreement and any other present or
future agreements. Any and all reasonable sums paid and any and all reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by
Silicon with respect to the foregoing shall be added to and become part of the
Obligations, shall be payable on demand, and shall bear interest at a rate equal
to the highest interest rate applicable to any of the Obligations. In no event
shall Silicon's rights under the foregoing power of attorney or any of Silicon's
other rights under this Agreement be deemed to indicate that Silicon is in
control of the business, management or properties of Borrower.

<PAGE>


   7.5 APPLICATION OF PROCEEDS. All proceeds realized as the result of any sale
of the Collateral shall be applied by Silicon first to the reasonable costs,
expenses, liabilities, obligations and attorneys' fees incurred by Silicon in
the exercise of its rights under this Agreement, second to the interest due upon
any of the Obligations, and third to the principal of the Obligations, in such
order as Silicon shall determine in its sole discretion. Any surplus shall be
paid to Borrower or other persons legally entitled thereto; Borrower shall
remain liable to Silicon for any deficiency. If, Silicon, in its sole
discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any sale of Collateral, Silicon shall
have the option, exercisable at any time, in its sole discretion, of either
reducing the Obligations by the principal amount of purchase price or deferring
the reduction of the Obligations until the actual receipt by Silicon of the cash
therefor.

   7.6 REMEDIES CUMULATIVE. In addition to the rights and remedies set forth in
this Agreement, Silicon shall have all the other rights and remedies accorded a
secured party under the California Uniform Commercial Code and under all other
applicable laws, and under any other instrument or agreement now or in the
future entered into between Silicon and Borrower, and all of such rights and
remedies are cumulative and none is exclusive. Exercise or partial exercise by
Silicon of one or more of its rights or remedies shall not be deemed an
election, nor bar Silicon from subsequent exercise or partial exercise of any
other rights or remedies. The failure or delay of Silicon to exercise any rights
or remedies shall not operate as a waiver thereof, but all rights and remedies
shall continue in full force and effect until all of the Obligations have been
fully paid and performed.

9. GENERAL PROVISIONS.

   9.1 INTEREST COMPUTATION. In computing interest on the Obligations, all
checks, wire transfers and other items of payment received by Silicon (including
proceeds of Receivables and payment of the Obligations in full) shall be deemed
applied by Silicon on account of the Obligations three Business Days after
receipt by Silicon of immediately available funds, and, for purposes of the
foregoing, any such funds received after 12:00 Noon on any day shall be deemed
received on the next Business Day. Silicon shall not, however, be required to
credit Borrower's account for the amount of any item of payment which is
unsatisfactory to Silicon in its sole discretion, and Silicon may charge
Borrower's loan account for the amount of any item of payment which is returned
to Silicon unpaid.

   9.2 APPLICATION OF PAYMENTS. All payments with respect to the Obligations may
be applied, and in Silicon's sole discretion reversed and re-applied, to the
Obligations, in such order and manner as Silicon shall determine in its sole
discretion.

   9.3 CHARGES TO ACCOUNTS. Silicon may, in its discretion, require that
Borrower pay monetary Obligations in cash to Silicon, or charge them to
Borrower's Loan account, in which event they will bear interest at the same rate
applicable to the Loans. Silicon may also, in its discretion, charge any
monetary Obligations to Borrower's Deposit Accounts maintained with Silicon.

   9.4 MONTHLY ACCOUNTINGS. Silicon shall provide Borrower monthly with an
account of advances, charges, expenses and payments made pursuant to this
Agreement. Such account shall be deemed correct, accurate and binding on

rendered, describing the nature of any alleged errors or admissions.

   9.7 INTEGRATION. This Agreement and such other written agreements, documents
and instruments as may be executed in connection herewith are the final, entire
and complete agreement between Borrower and Silicon and supersede all prior and
contemporaneous negotiations and oral representations and agreements, all of
which are merged and integrated in this Agreement. There are no oral
understandings, representations or agreements between the parties which are not
set forth in this Agreement or in other written agreements signed by the parties
in connection herewith.

   9.8 WAIVERS. The failure of Silicon at any time or times to require Borrower
to strictly comply with any of the provisions of this Agreement or any other
present or future agreement between Borrower and Silicon shall not waive or
diminish any right of Silicon later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement now or in the future
executed by Borrower and delivered to Silicon shall be deemed to have been
waived by any act or knowledge of Silicon or its agents or employees, but only
by a specific written waiver signed by an authorized officer of Silicon and
delivered to Borrower. Borrower waives demand, protest, notice of protest and
notice of default or dishonor, notice of payment and nonpayment, release,
compromise, settlement, extension or renewal of any commercial paper,
instrument, account, General Intangible, document or guaranty at any time held
by Silicon on which Borrower is or may in any way be liable, and notice of any
action taken by Silicon, unless expressly required by this Agreement.

   9.9 NO LIABILITY FOR ORDINARY NEGLIGENCE. Neither Silicon, nor any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or representing Silicon shall be liable for any claims, demands, losses or
damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower
or any other party through the ordinary negligence of Silicon, or any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or representing Silicon, but nothing herein shall relieve Silicon from
liability for its own gross negligence or willful misconduct.

   9.10 AMENDMENT. The terms and provisions of this Agreement may not be waived
or amended, except in a writing executed by Borrower and a duly authorized
officer of Silicon.

   9.11 TIME OF ESSENCE. Time is of the essence in the performance by Borrower
of each and every obligation under this Agreement.

   9.12 ATTORNEYS FEES AND COSTS. Borrower shall reimburse Silicon for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by Silicon, pursuant to,
or in connection with, or relating to this Agreement (whether or not a lawsuit
is filed), including, but not limited to, any reasonable attorneys' fees and
costs Silicon incurs in order to do the following: prepare and negotiate this
Agreement and the documents relating to this Agreement; obtain legal advice in
connection with this Agreement or Borrower; enforce, or seek to enforce, any of
its rights; prosecute actions against, or defend actions by, Account Debtors;
commence, intervene in, or defend any action or proceeding; initiate any
complaint to be relieved of the automatic stay in bankruptcy; file or prosecute
any probate claim, bankruptcy claim, third-party claim, or other claim; examine,
audit, copy, and inspect any of the Collateral or any of Borrower's books and
records; protect, obtain possession of, lease, dispose of, or otherwise enforce
Silicon's security interest in, the Collateral; and otherwise represent Silicon
in any litigation relating to Borrower. In satisfying Borrower's obligation
hereunder to reimburse Silicon for attorneys fees, Borrower may, for
convenience, issue checks directly to Silicon's attorneys, Levy, Small & Lallas,
but Borrower acknowledges and agrees that Levy, Small & Lallas is representing
only Silicon and not Borrower in connection with this Agreement. If either
Silicon or Borrower files any lawsuit against the other predicated on a breach
of this Agreement, the prevailing party in such action shall be entitled to
recover its reasonable costs and attorneys' fees, including (but not limited to)

   EXIM AGREEMENT;
   CROSS-COLLATERALIZATION;
   CROSS-DEFAULT:

                Silicon and the Borrower are parties to that certain Loan and
                Security Agreement (Exim Program) of even date (the "Exim
                Agreement"). Both this Agreement and the Exim Agreement shall
                continue in full force and effect, and all rights and remedies
                under this Agreement and the Exim Agreement are cumulative. The
                term "Obligations" as used in this Agreement and in the Exim
                Agreement shall include without limitation the obligation to pay
                when due all Loans made pursuant to this Agreement (the
                "Non-Exim Loans") and all interest thereon and the obligation to


                                       -1-
<PAGE>


                pay when due all Loans made pursuant to the Exim Agreement (the
                "Exim Loans") and all interest thereon. Without limiting the
                generality of the foregoing, all "Collateral" as defined in this
                Agreement and as defined in the Exim Agreement shall secure all
                Exim Loans and all Non-Exim Loans and all interest thereon, and
                all other Obligations. Any Event of Default under this Agreement
                shall also constitute an Event of Default under the Exim
                Agreement, and any Event of Default under the Exim Agreement
                shall also constitute an Event of Default under this Agreement.
                In the event Silicon assigns its rights under the Exim Agreement
                and/or under any Note evidencing Exim Loans and/or its rights
                under this Agreement and/or under any Note evidencing Non-Exim
                Loans, to any third party, including without limitation the
                Export-Import Bank of the United States ("Exim Bank"), whether
                before or after the occurrence of any Event of Default, Silicon
                shall have the right (but not any obligation), in its sole
                discretion, to allocate and apportion Collateral to the
                Agreement and/or Note assigned and to specify the priorities of
                the respective security interests in such Collateral between
                itself and the assignee, all without notice to or consent of the
                Borrower.

2. INTEREST.

   INTEREST RATE (Section 1.2):

                A rate equal to the "Prime Rate" in effect from time to time,
                plus 2.25% per annum. Interest shall be calculated on the basis
                of a 360-day year for the actual number of days elapsed. "Prime
                Rate" means the rate announced from time to time by Silicon as
                its "prime rate;" it is a base rate upon which other rates
                charged by Silicon are based, and it is not necessarily the best
                rate available at Silicon. The interest rate applicable to the
                Obligations shall change on each date there is a change in the
                Prime Rate.

                Interest on the Loans is subject to Exhibit A hereto.

   MINIMUM MONTHLY
   INTEREST (Section 1.2):

                $2,500 per month in the aggregate as between this Agreement and
                the Exim Agreement.

                        control agreement in form acceptable to Silicon in its
                        good faith business judgment in order to perfect
                        Silicon's security interest in said Deposit Accounts and
                        investment accounts.

                        maintains inventory to execute and deliver to Silicon,
                        on Silicon's standard form, a landlord waiver containing

                        the Borrower, at $______ per share (which price is equal
                        to the average closing price per share of the common
                        stock of Borrower for the 10 trading days immediately
                        preceding the Issue Date of the Warrant to Purchase
                        Stock, or, at Borrower's option, the 10 trading days
                        immediately preceding September 14, 2001), on terms
                        acceptable to Silicon, as set forth in the Warrant to
                        Purchase Stock and related documents being executed
                        concurrently with this Agreement. Said warrants shall be
                        deemed fully earned on the date hereof, shall be in
                        addition to all interest and other fees, and shall be
                        non-refundable.

                (6)     COPYRIGHT FILINGS. Concurrently herewith, Borrower is

                                    EXHIBIT A

                         PROVISIONS RELATING TO INTEREST

Notwithstanding the provisions of this Agreement regarding the rates of interest
applicable to the Loans, if at any time the amount of such interest computed on
the basis of the interest rate set forth herein (the "Applicable Interest Rate")
would exceed the amount of such interest computed upon the basis of the maximum
rate of interest permitted by applicable state or federal law in effect from
time to time hereafter, after taking into account, to the extent required by
applicable law, any and all fees, payments, charges and calculations provided
for in this Agreement or in any other agreement between Borrower and Silicon
(the "Maximum Legal Rate"), the interest payable under this Agreement shall be
computed upon the basis of the Maximum Legal Rate, but any subsequent reduction
in the Applicable Interest Rate shall not reduce such interest thereafter
payable hereunder below the amount computed on the basis of the Maximum Legal
Rate until the aggregate amount of such interest accrued and payable under this
Agreement equals the total amount of interest which would have accrued if such
interest had been at all times computed solely on the basis of the Applicable
Interest Rate.

No agreements, conditions, provisions or stipulations contained in this
Agreement or any other instrument, document or agreement between the Borrower
and Silicon or default of the Borrower, or the exercise by Silicon of the right
to accelerate the payment of the maturity of principal and interest, or to
exercise any option whatsoever contained in this Agreement or any other
agreement between the Borrower and Silicon, or the arising of any contingency
whatsoever, shall entitle Silicon to collect, in any event, interest exceeding
the Maximum Legal Rate and in no event shall the Borrower be obligated to pay
interest exceeding such Maximum Legal Rate and all agreements, conditions or
stipulations, if any, which may in any event or contingency whatsoever operate
to bind, obligate or compel the Borrower to pay a rate of interest exceeding the
Maximum Legal Rate, shall be without binding force or effect, at law or in
equity, to the extent only of the excess of interest over such Maximum Legal
Rate. In the event any interest is charged in excess of the Maximum Legal Rate
("Excess"), the Borrower acknowledges and stipulates that any such charge shall
be the result of an accidental and bona fide error, and such Excess shall be,
first, applied to reduce the principal then unpaid hereunder; second, applied to
reduce the Obligations; and third, returned to the Borrower, it being the
intention of the parties hereto not to enter at any time into a usurious or
otherwise illegal relationship. The Borrower recognizes that, with fluctuations
in the Applicable Interest Rate and the Maximum Legal Rate, such an
unintentional result could inadvertently occur. By the execution of this
Agreement, the Borrower covenants that (i) the credit or return of any Excess
shall constitute the acceptance by the Borrower of such Excess, and (ii) the
Borrower shall not seek or pursue any other remedy, legal or equitable, against
Silicon, based in whole or in part upon the charging or receiving of any
interest in excess of the maximum authorized by applicable law. For the purpose
of determining whether or not any Excess has been contracted for, charged or
received by Silicon, all interest at any time contracted for, charged or
received by Silicon in connection with this Agreement shall be amortized,
prorated, allocated and spread in equal parts during the entire term of this
Agreement.

The provisions of this Exhibit shall be deemed to be incorporated into every
document or communication relating to the Obligations which sets forth or
prescribes any account, right or claim or alleged account, right or claim of
Silicon with respect to the Borrower (or any other obligor in respect of
Obligations), whether or not any provision of this Exhibit is referred to
therein. All such documents and communications and all figures set forth therein
shall, for the sole purpose of computing the extent of the liabilities and
obligations of the Borrower (or other obligor) asserted by Silicon thereunder,
be automatically recomputed by any Borrower or obligor, and by any court
considering the same, to give effect to the adjustments or credits required by
this Exhibit.

If the applicable state or federal law is amended in the future to allow a
greater rate of interest to be charged under this Agreement or any other Loan
Documents than is presently allowed by applicable state or federal law, then the
limitation of interest under this Exhibit shall be increased to the maximum rate
of interest allowed by applicable state or federal law as amended, which
increase shall be effective hereunder on the effective date of such amendment,
and all interest charges owing to Silicon by reason thereof shall be payable
upon demand.
