EXHIBIT 10.36

Comerica

                              MASTER REVOLVING NOTE
  Variable Rate-Demand-Obligatory Advances (Business and Commercial Loans Only)

AMOUNT                     $2,000,000.00
NOTE DATE                  September 08, 2003
MATURITY DATE              ON DEMAND
TAX IDENTIFICATION #       77-0213001

For Value Received, the undersigned promise(s) to pay ON DEMAND to the order of
Comerica Bank-California ("Bank"), at any office of the Bank in the State of
California, Two Million and no/100 Dollars (U.S.) (or that portion of it
advanced by the Bank and not repaid as later provided) with interest until
demand or an Event of Default, as later defined, at a per annum rate equal to
the Bank's base rate from time to time in effect minus 0.250 % per annum and
after that at a rate equal to the rate of interest otherwise prevailing under
this Note plus 3% per annum (but in no event in excess of the maximum rate
permitted by law). The Bank's "base rate" is that annual rate of interest so
designated by the Bank and which is changed by the Bank from time to time.
Interest rate changes will be effective for interest computation purposes as and
when the Bank's base rate changes. Interest shall be calculated on the basis of
a 360-day year for the actual number of days the principal is outstanding.
Unless sooner demanded, accrued interest on this Note shall be payable on the
1st day of each MONTH commencing October 01, 2003. If the frequency of interest
payments is not otherwise specified, accrued interest on this Note shall be
payable monthly on the first day of each month, unless sooner demanded. If any
payment of principal or interest under this Note shall be payable on a day other
than a day on which the Bank is open for business, this payment shall be
extended to the next succeeding business day and interest shall be payable at
the rate specified in this Note during this extension. A late payment charge
equal to 5% of each late payment may be charged on any payment not received by
the Bank within 10 calendar days after the payment due date, but acceptance of
payment of this charge shall not waive any Default under this Note.

The principal amount payable under this Note shall be the sum of all advances
made by the Bank to or at the request of the undersigned, less principal
payments actually received in cash by the Bank. The books and records of the
Bank shall be the best evidence of the principal amount and the unpaid interest
amount owing at any time under this Note and shall be conclusive absent manifest
error. No interest shall accrue under this Note until the date of the first
advance made by the Bank; after that interest on all advances shall accrue and
be computed on the principal balance outstanding from time to time under this
Note until the same is paid in full.

This Note and any other indebtedness and liabilities of any kind of the
undersigned (or any of them) to the Bank, and any and all modifications,
renewals or extensions of it, whether joint or several, contingent or absolute,
now existing or later arising, and however evidenced (collectively
"Indebtedness") are secured by and the Bank is granted a security interest in
all items deposited in any account of any of the undersigned with the Bank and
by all proceeds of these items (cash or otherwise), all account balances of any
of the undersigned from time to time with the Bank, by all property of any of
the undersigned from time to time in the possession of the Bank and by any other
collateral, rights and properties described in each and every deed of trust,
mortgage, security agreement, pledge, assignment and other security or
collateral agreement which has been, or will at any time(s) later be, executed
by any (or all) of the undersigned to or for the benefit of the Bank
(collectively "Collateral"). Notwithstanding the above, (i) to the extent that
any portion of the Indebtedness is a consumer loan, that portion shall not be
secured by any deed of trust or mortgage on or other security interest in any of
the undersigned's principal dwelling or any of the undersigned's real property
which is not a purchase money security interest as to that portion, unless
expressly provided to the contrary in another place, or (ii) if the undersigned
(or any of them) has (have) given or give(s) Bank a deed of trust or mortgage
covering real property, that deed of trust or mortgage shall not secure this
Note or any other Indebtedness of the undersigned (or any of them), unless
expressly provided to the contrary in another place.

If the undersigned (or any of them) or any guarantor under a guaranty of all or
part of the Indebtedness ("guarantor") (i) fail(s) to pay any of the
Indebtedness when due, by maturity, acceleration or otherwise, or fail(s) to pay
any Indebtedness owing on a demand basis upon demand; or (ii) fail(s) to comply
with any of the terms or provisions of any agreement between the undersigned (or
any of them) or any such guarantor and the Bank; or (iii) become(s) insolvent or
the subject of a voluntary or involuntary proceeding in bankruptcy, or a
reorganization arrangement or creditor composition proceeding, (if a business
entity) cease(s) doing business as a going concern, (if a natural person) die(s)
or become(s) incompetent, (if a partnership) dissolve(s) or any general partner
of it dies, becomes incompetent or becomes the subject of a bankruptcy
proceeding or (if a corporation or a limited liability company) is the subject
of a dissolution, merger or consolidation; or (a) if any warranty or
representation made by any of the undersigned or any guarantor in connection
with this Note or any of the Indebtedness shall be discovered to be untrue or
incomplete; or (b) if there is any termination, notice of termination, or breach
of any guaranty, pledge, collateral assignment or subordination agreement
relating to all or any part of the Indebtedness; or (c) if there is any failure
by any of the undersigned or any guarantor to pay when due any of its
indebtedness (other than to the Bank) or in the observance or performance of any
term covenant or condition in any document evidencing, securing or relating to
such indebtedness; or (d) if the Bank deems itself insecure believing that the
prospect of payment of this Note or any of the indebtedness is impaired or shall
fear deterioration, removal or waste of any of the Collateral; or (e) if there
is filed or issued a levy or writ of attachment or garnishment or other like
judicial process upon the undersigned (or any of them) or any guarantor or any
of the Collateral, including without limit, any accounts of the undersigned (or
any of them) or any guarantor with the Bank, then the Bank, upon the occurrence
of any of these events (each a "Default"), may at its option and without prior
notice to the undersigned (or any of them), declare any or all of the
Indebtedness to be immediately due and payable (notwithstanding any provisions
contained in the evidence of it to the contrary), cease advancing money or
extending credit to or for the benefit of the undersigned under this Note or any
other agreement between the undersigned and Bank, terminate this Note as to any
future liability or obligation of Bank, but without affecting Bank's rights and
security interests in any Collateral and the indebtedness of the undersigned to
Bank, sell or liquidate all or any portion of the Collateral, set off against
the Indebtedness any amounts owing by the Bank to the undersigned (or any of
them), charge interest at the default rate provided in the document evidencing
the relevant Indebtedness and exercise any one or more of the rights and
remedies granted to the Bank by any agreement with the undersigned (or any of
them) or given to it under applicable law. In addition, if this Note is secured
by a deed of trust or mortgage covering real property, then the trustor or
mortgagor shall not mortgage or pledge the mortgaged premises as security for
any other indebtedness or obligations. This Note, together with all other
Indebtedness secured by said deed of trust or mortgage, shall become due and
payable immediately, without notice at the option of the Bank (a) if said
trustor or mortgagor shall mortgage or pledge the mortgaged premises for any
other indebtedness or obligations or shall convey, assign or transfer the
mortgaged premises by deed, installment sale contract or other instrument, or
(b) if the title to the mortgaged premises shall become vested in any other
person or party in any manner whatsoever, or (c) if there is any disposition
(through one or more transactions) of legal or beneficial title to a controlling
interest of said trustor or mortgagor.

The undersigned acknowledge(s) that this Note matures upon issuance, and that
the Bank, at any time, without notice, and without reason, may demand that this
Note be immediately paid in full. The demand nature of this Note shall not be
deemed modified by reference to a Default in this Note or in any agreement to a
default by the undersigned or to the occurrence of an event of default
(collectively an "Event of Default'). For purposes of this Note, to the extent
there is reference to an Event of Default this reference is for the purpose of
permitting the Bank to accelerate indebtedness not on a demand basis and to
receive interest at the default rate provided in the document evidencing the
relevant indebtedness. It is expressly agreed that the Bank may exercise its
demand rights under this Note whether or not an Event of Default has occurred.
The Bank, with or without reason and without notice, may from time to time make
demand for partial payments under this Note and these

<PAGE>

demands shall not preclude the Bank from demanding at any time that this Note be
immediately paid In full. All payments under this note shall be in immediately
available United States funds, without setoff or counterclaim.

If this note is signed by two or more parties (whether by all as makers or by
one or more as an accommodation party or otherwise), the obligations and
undertakings under this Note shall be that of all and any two or more jointly
and also of each severally. This Note shall bind the undersigned, and the
undersigned's respective heirs, personal representatives, successors and
assigns.

The undersigned waive(s) presentment, demand, protest, notice of dishonor,
notice of demand or intent to demand, notice of acceleration or intent to
accelerate, and all other notices and agree(s) that no extension or indulgence
to the undersigned (or any of them) or release, substitution or nonenforcement
of any security, or release or substitution of any of the undersigned, any
guarantor or any other party, whether with or without notice, shall affect the
obligations of any of the undersigned. The undersigned waive(s) all defenses or
right to discharge available under Section 3-605 of the California Uniform
Commercial Code and waive(s) all other suretyship defenses or right to
discharge. The undersigned agree(s) that the Bank has the right to sell, assign,
or grant participations, or any interest, in any or all of the indebtedness, and
that, in connection with this right, but without limiting its ability to make
other disclosures to the full extent allowable, the Bank may disclose all
documents and information which the Bank now or later has relating to the
undersigned or the indebtedness. The undersigned agree(s) that the Bank may
provide information relating to the Note or to the undersigned to the Bank's
parent, affiliates, subsidiaries and service providers.

The undersigned agree(s) to reimburse the holder or owner of this Note for any
and all costs and expenses (including without limit, court costs, legal expenses
and reasonable attorney fees, whether inside or outside counsel is used, whether
or not suit is instituted and, if suit is instituted, whether at the trial court
level, appellate level, in a bankruptcy, probate or administrative proceeding or
otherwise) incurred in collecting or attempting to collect this Note or incurred
in any other matter or proceeding relating to this Note.

The undersigned acknowledge(s) and agree(s) that there are no contrary
agreements, oral or written, establishing a term of this Note and agree(s) that
the terms and conditions of this Note may not be amended, waived or modified
except in a writing signed by an officer of the Bank expressly stating that the
writing constitutes an amendment, waiver or modification of the terms of this
Note. As used in this Note, the word "undersigned" means, individually and
collectively, each maker, accommodation party, indorser and other party signing
this Note in a similar capacity. If any provision of this Note is unenforceable
in whole or part for any reason, the remaining provisions shall continue to be
effective. THIS NOTE IS MADE IN THE STATE OF CALIFORNIA AND SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF CALIFORNIA,
WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES.

The maximum interest rate shall not exceed the highest applicable usury ceiling.

THE UNDERSIGNED AND THE BANK ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A
CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. EACH PARTY, AFTER CONSULTING (OR
HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR CHOICE, KNOWINGLY
AND VOLUNTARILY, AND FOR THEIR MUTUAL BENEFIT, WAIVES ANY RIGHT TO TRIAL BY JURY
IN THE EVENT OF LITIGATION REGARDING THE PERFORMANCE OR ENFORCEMENT OF, OR IN
ANY WAY RELATED TO, THIS NOTE OR THE INDEBTEDNESS.

Until full and final payment of the Indebtedness and so long as Bank has any
obligation to advance funds under the Note, Borrower hereby warrants and agrees
to maintin a zero ($0.00) outstanding balance for an minimum period of thirty
(30) consecutive days each calendar year.

2. Interest Rate Options. Borrower shall have the following options regarding
the interest rate to be paid by Borrower on Advances under the Note:

a. A rate equal to two and one half percent (2.50%) above Bank's LIBOR, (the
"LIBOR Option"), which LIBOR Option shall be in effect during the relevant LIBOR

4. Payment of Interest on LIBOR Option Advances. Interest on each LIBOR Option
Advance shall be payable pursuant to the terms of the Note. Interest on such
LIBOR Option Advance shall be computed on the basis of a 360-day year and shall
be assessed for the actual number of days elapsed from the first day of the
LIBOR Period applicable thereto but not including the last day thereof.

5. Bank's Records Re: LIBOR Option Advances. With respect to each LIBOR Option
Advance, Bank is hereby authorized to note the date, principal amount, interest
rate and LIBOR Period applicable thereto and any payments made thereon on Bank's
books and records (either manually or by electronic entry) and/or on any
schedule attached to the Note, which notations shall be prima facie evidence of
the accuracy of the information noted.

6. Selection/Conversion of Interest Rate Options. At the time any Advance is
requested under the Note and/or Borrower wishes to select the LIBOR Option for
all or a portion of the outstanding principal balance of the Note, and at the
end of each LIBOR Period, Borrower shall give Bank notice specifying (a) the
interest rate option selected by Borrower; (b) the principal amount subject
thereto; and (c) if the LIBOR Option is selected, the length of the applicable
LIBOR Period. Any such notice may be given by telephone so long as, with respect
to each LIBOR Option selected by Borrower, (i) Bank receives written
confirmation from Borrower not later than three (3) LIBOR Business Days after
such telephone notice is given; and (ii) such notice is given to Bank prior to
10:00 a.m., California time, on the first day of the LIBOR Period. For each
LIBOR Option requested hereunder, Bank will quote the applicable fixed LIBOR
Rate to Borrower at approximately 10:00 a.m., California time, on the first day
of the LIBOR Period. If Borrower does not immediately accept the rate quoted by
Bank, any subsequent acceptance by Borrower shall be subject to a
redetermination of the rate by Bank; provided, however, that if Borrower fails
to accept any such quotation given, then the quoted rate shall expire and Bank
shall have no obligation to permit a LIBOR Option to be selected on such day. If
no specific designation of interest is made at the time any Advance is requested
under the Note or at the end of any LIBOR Period, Borrower shall be deemed to
have selected the Base Rate Option for such Advance or the principal amount to
which such LIBOR Period applied. At any time the LIBOR Option is in effect,
Borrower may, at the end of the applicable LIBOR Period, convert to the Base
Rate Option. At any time the Base Rate Option is in effect, Borrower may convert
to the LIBOR OPTION, and shall designate a LIBOR Period.

7. Default Interest Rate. From and after the maturity date of the Note, or such
earlier date as all principal owing hereunder becomes due and payable by
acceleration or otherwise, the outstanding principal balance of the Note shall
bear interest until paid in full at an increased rate per annum (computed on the
basis of a 360-day year, actual days elapsed) equal to three percent (3.00%)
above the rate of interest from time to time applicable to the Note.

8. Prepayment. In the event that the LIBOR Option is the applicable interest
rate for all or any part of the outstanding principal balance of the Note, and
any payment or prepayment of any such outstanding principal balance of the Note
shall occur on any day other than the last day of the applicable LIBOR Period
(whether voluntarily, by acceleration, required payment, or otherwise), or if
Borrower elects the LIBOR Option as the applicable interest rate for all or any
part of the outstanding principal balance of the Note in accordance with the
terms and conditions hereof, and, subsequent to such election, but prior to the
commencement of the applicable LIBOR Period, Borrower revokes such election for
any reason whatsoever, or if the applicable interest rate in respect of any
outstanding principal balance of the Note hereunder shall be changed, for any
reason whatsoever, from the LIBOR Option to the Base Rate Option prior to the
last day of the applicable LIBOR Period, or if Borrower shall fail to make any
payment of principal or interest hereunder at any time that the LIBOR Option is
the applicable interest rate hereunder in respect of such outstanding principal
balance of the Note, Borrower shall reimburse Bank, on demand, for any resulting
loss, cost or expense incurred by Bank as a result thereof, including,

<PAGE>

without limitation, any such loss, cost or expense incurred in obtaining,
liquidating, employing or redeploying deposits from third parties. Such amount
payable by Borrower to Bank may include, without limitation, an amount equal to
the excess, if any, of (a) the amount of interest which would have accrued on
the amount so prepaid, or not so borrowed, refunded or converted, for the period
from the date of such prepayment or of such failure to borrow, refund or
convert, through the last day of the relevant LIBOR Period, at the applicable
rate of interest for such outstanding principal balance of the Note, as provided
under this Note, over (b) the amount of interest (as reasonably determined by
Bank) which would have accrued to Bank on such amount by placing such amount on
deposit for a comparable period with leading banks in the interbank LIBOR
market. Calculation of any amounts payable to Bank under this paragraph shall be
made as though Bank shall have actually funded or committed to fund the relevant
outstanding principal balance of the Note hereunder through the purchase of an
underlying deposit in an amount equal to the amount of such outstanding
principal balance of the Note and having a maturity comparable to the relevant
LIBOR Period; provided, however, that Bank may fund the outstanding principal
balance of the Note hereunder in any manner it deems fit and the foregoing
assumptions shall be utilized only for the purpose of the calculation of amounts
payable under this paragraph. Upon the written request of Borrower, Bank shall
deliver to Borrower a certificate setting forth the basis for determining such
losses, costs and expenses, which certificate shall be conclusively presumed
correct, absent manifest error. Any prepayment hereunder shall also be
accompanied by the payment of all accrued and unpaid interest on the amount so
prepaid. Any outstanding principal balance of the Note which is bearing interest
at such time at the Base Rate Option may be prepaid without penalty or premium.
Partial prepayments hereunder shall be applied to the installments hereunder in
the inverse order of their maturities.

BY INITIALING BELOW, BORROWER ACKNOWLEDGE(S) AND AGREE(S) THAT: (A) THERE IS NO
RIGHT TO PREPAY ANY LIBOR OPTION ADVANCE, IN WHOLE OR IN PART, WITHOUT PAYING
THE PREPAYMENT AMOUNT SET FORTH HEREIN ("PREPAYMENT AMOUNT"), EXCEPT AS
OTHERWISE REQUIRED UNDER APPLICABLE LAW; (B) BORROWER SHALL BE LIABLE FOR
PAYMENT OF THE PREPAYMENT AMOUNT IF BANK EXERCISES ITS RIGHT TO ACCELERATE
PAYMENT OF ANY LIBOR OPTION ADVANCE AS PART OR ALL OF THE OBLIGATIONS OWING
UNDER THE NOTE, INCLUDING WITHOUT LIMITATION, ACCELERATION UNDER A DUE-ON-SALE
PROVISION; (C) BORROWER WAIVES ANY RIGHTS UNDER SECTION 2954.10 OF THE
CALIFORNIA CIVIL CODE OR ANY SUCCESSOR STATUTE; AND (D) BANK HAS MADE EACH LIBOR
OPTION ADVANCE PURSUANT TO THE NOTE IN RELIANCE ON THESE AGREEMENTS.

BORROWER'S INITIALS

9. Hold Harmless and Indemnification. Borrower agrees to indemnify Bank and to
hold Bank harmless from, and to reimburse Bank on demand for, all losses and
expenses which Bank sustains or incurs as a result of (i) any payment of a LIBOR
Option Advance prior to the last day of the applicable LIBOR Period for any
reason, including, without limitation, termination of the Note, whether pursuant
to this Addendum or the occurrence of an Event of Default; (ii) any termination
of a LIBOR Period prior to the date it would otherwise end in accordance with
this Addendum; or (iii) any failure by Borrower, for any reason, to borrow any
portion of a LIBOR Option Advance.

10. Funding Losses. The indemnification and hold harmless provisions set forth
in this Addendum shall include, without limitation, all losses and expenses
arising from interest and fees that Bank pays to lenders of funds it obtains in
order to fund the loans to Borrower on the basis of the LIBOR Option(s) and all
losses incurred in liquidating or re-deploying deposits from which such funds
were obtained and loss of profit for the period after termination. A written
statement by Bank to Borrower of such losses and expenses shall be conclusive
and binding, absent manifest error, for all purposes. This obligation shall
survive the termination of this Addendum and the payment of the Note.

11. Regulatory Developments Or Other Circumstances Relating To Illegality or
Impracticality of LIBOR. If any Regulatory Development or other circumstances
relating to the interbank Euro-dollar markets shall, at any time, in Bank's
reasonable determination, make it unlawful or impractical for Bank to fund or
maintain, during any LIBOR Period, to determine or charge interest rates based
upon LIBOR, Bank shall give notice of such circumstances to Borrower and:

(i) In the case of a LIBOR Period in progress, Borrower shall, if requested by
Bank, promptly pay any interest which had accrued prior to such request and the
date of such request shall be deemed to be the last day of the term of the LIBOR
Period; and

(ii) No LIBOR Period may be designated thereafter until Bank determines that
such would be practical.

12. Additional Costs. Borrower shall pay to Bank from time to time, upon Bank's
request, such amounts as Bank determines are needed to compensate Bank for any
costs it incurred which are attributable to Bank having made or maintained a
LIBOR Option Advance or to Bank's obligation to make a LIBOR Option Advance, or
any reduction in any amount receivable by Bank hereunder with respect to any
LIBOR Option or such obligation (such increases in costs and reductions in
amounts receivable being herein called "Additional Costs"), resulting from any
Regulatory Developments, which (i) change the basis of taxation of any amounts
payable to Bank hereunder with respect to taxation of any amounts payable to
Bank hereunder with respect to any LIBOR Option Advance (other than taxes
imposed on the overall net income of Bank for any LIBOR Option Advance by the
jurisdiction where Bank is headquartered or the jurisdiction where Bank extends
the LIBOR Option Advance; (ii) impose or modify any reserve, special deposit, or
similar requirements relating to any extensions of credit or other assets of, or
any deposits with or other liabilities of, Bank (including any LIBOR Option
Advance or any deposits referred to in the definition of LIBOR); or (iii) impose
any other condition affecting this Addendum (or any of such extension of credit
or liabilities). Bank shall notify Borrower of any event occurring after the
date hereof which entitles Bank to compensation pursuant to this paragraph as
promptly as practicable after it obtains knowledge thereof and determines to
request such compensation. Determinations by Bank for purposes of this
paragraph, shall be conclusive, provided that such determinations are made on a
reasonable basis.

13. Legal Effect. Except as specifically modified hereby, all of the terms and
conditions of the Note remain in full force and effect.

IN WITNESS WHEREOF, the parties have agreed to the foregoing as of the date
first set forth above.

thereof; (d) accept partial payments on the Indebtedness; (e) receive and hold
additional security or guaranties for the Indebtedness or any part thereof; (f)
release, reconvey, terminate, waive, abandon, fail to perfect, subordinate,
exchange, substitute, transfer, or enforce any security or guaranties, and apply
any security and direct the order or manner of sale thereof as Bank in its sole
and absolute discretion may determine; (g) release any Person from any personal
liability with respect to the Indebtedness or any part thereof; (h) settle,
release on terms satisfactory to Bank or by operation of applicable laws, or
otherwise liquidate or enforce any Indebtedness and any security therefor or
guaranty thereof in any manner, consent to the transfer of any security and bid
and purchase at any sale; or (i) consent to the merger, change, or any other
restructuring or termination of the corporate or partnership existence of any
Borrower or any other Person, and correspondingly restructure the Indebtedness,
and any such merger, change, restructuring, or termination shall not affect the
liability of any Borrower or the continuing effectiveness hereof, or the
enforceability hereof with respect to all or any part of the Indebtedness.

(2) Upon the occurrence and during the continuance of any Event of Default, Bank
may enforce the Agreement and the other Loan Documents independently as to each
Borrower and independently of any other remedy or security Bank at any time may
have or hold in connection with the Indebtedness, and it shall not be necessary
for Bank to marshal assets in favor of any Borrower or any other Person or to
proceed upon or against or exhaust any security or remedy before proceeding to
enforce the Agreement and the other Loan Documents. Each Borrower expressly
waives any right to require Bank to marshal assets in favor of any Borrower or
any other Person or to proceed against any other Borrower or any Collateral
provided by any Person, and agrees that Bank may proceed against Borrowers or
any Collateral in such order as it shall determine in its sole and absolute
discretion.

(3) Bank may file a separate action or actions against any Borrower, whether
action is brought or prosecuted with respect to any security or against any
other person, or whether any other person is joined in any such action or
actions. Each Borrower agrees that Bank and any Borrower and any affiliate of
any Borrower may deal with each other in connection with the Indebtedness or
otherwise, or alter any contracts or agreements now or hereafter existing
between any of them, in any manner whatsoever, all without in any way altering
or affecting the continuing efficacy of the Agreement or the other Loan
Documents.

(4) Bank's rights under the Loan Documents shall be reinstated and revived, and
the enforceability of the Agreement and the other Loan Documents shall continue,
with respect to any amount at any time paid on account of the Indebtedness which
thereafter shall be required to be restored or returned by Bank, all as though
such amount had not been paid. The rights of Bank created or granted herein and
the enforceability of the Agreement and the other Loan Documents at all times
shall remain effective to cover the full amount of all the Indebtedness even
though the Indebtedness, including any part thereof or any other security or
guaranty therefor, may be or hereafter may become invalid or otherwise
unenforceable as against any Borrower and whether or not any other Borrower
shall have any personal liability with respect thereto.

(5) To the maximum extent permitted by applicable law and to the extent that a
Borrower is deemed a guarantor, each Borrower expressly waives any and all
defenses now or hereafter arising or asserted by reason of (a) any disability or
other defense of any other Borrower with respect to the Indebtedness, (b) the
unenforceabillty or invalidity of any security or guaranty for the Indebtedness
or lack of perfection or continuing perfection or failure of priority of any
security for the Indebtedness, (c) the cessation for any cause whatsoever of the
liability of any other Borrower (other than by reason of the full payment and
performance of all Indebtedness), (d) any failure of the Bank to marshal assets
in favor of Bank or any Borrower or any other person, (e) any failure of Bank to
give notice of sale or other disposition of collateral to any Borrower or any
other Person or any defect in any notice that may be given in connection with
any sale or disposition of collateral, (f) any failure of Bank to comply with
applicable law in connection with the sale or other disposition of any
collateral or other security for any Obligation, including any failure of Bank
to conduct a commercially reasonable sale or other disposition of any collateral
or other security for any Obligation, (g) any act or omission of Bank or others
that directly or indirectly results in or aids the discharge or release of any
Borrower or the Indebtedness or any security or guaranty therefor by operation
of law or otherwise, (h) any law which provides that the obligation of a surety
or guarantor must neither be larger in amount nor in other respects more
burdensome than that of the principal or which reduces a surety's or guarantor's
obligation in proportion to the principal obligation, (i) any failure of Bank to
file or enforce a claim in any bankruptcy or other proceeding with respect to
any Person, (j) the election by Bank of the application or nonapplication of
Section 1111(b)(2) of the United States Bankruptcy Code, (k) any extension of
credit or the grant of any lien under Section 364 of the United States
Bankruptcy Code, (1) any use of cash collateral under Section 363 of the United
States Bankruptcy Code, (m) any agreement or stipulation with respect to the
provision of adequate protection in any bankruptcy proceeding of any Person, (n)
the avoidance of any lien in favor of Bank for any reason, or (o) any action
taken by Bank that is authorized by the Agreement or any other provision of any
Loan Document. Until such time as all of the Indebtedness have been fully,
finally, and indefeasibly paid in full in cash: (i) each Borrower hereby waives
and postpones any right of subrogation it has or may have as against any other
Borrower respect to the Indebtedness; and (ii) in addition, each Borrower also
hereby waives and postpones any right to proceed or to seek recourse against or
with respect to any property or asset of any other Borrower. Each Borrower
expressly waives all setoffs and counterclaims and all presentments, demands for
payment or performance, notices of nonpayment or nonperformance, protests,
notices of protest, notices of dishonor and all other notices or demands of any
kind or nature whatsoever with respect to the Indebtedness, and all notices of
acceptance of the Agreement or the other Loan Documents or of the existence,
creation or incurring of new or additional Indebtedness.

(6) In the event that all or any part of the Indebtedness at any time are
secured by any one or more deeds of trust or mortgages or other instruments
creating or granting liens on any interests in real property, each Borrower
authorizes Bank, upon the occurrence of and during the continuance of any Event
of Default, at its sole option, without notice or demand and without affecting
the obligations of any Borrower, the enforceability of the Agreement and the
other Loan Documents, or the validity or enforceability of any liens of Bank, to
foreclose any or all of such deeds of trust or mortgages or other instruments by
judicial or nonjudicial sale.

(7) Without limiting the generality of any other waiver or other provision set
forth in this Agreement, each Borrower waives all rights and defenses that such
Borrower may have because the Indebtedness is secured by real property. This
means, among other things:

(i) Bank may collect from any Borrower without first foreclosing on any real or
personal property pledged as Collateral by any other Borrower to secure the
Indebtedness.

(ii) If Bank forecloses on any real property pledged as Collateral by any
Borrower:

(a) the amount of the debt may be reduced only by the price for which that
Collateral is sold at the foreclosure sale, even if the collateral is worth more
than the sale price.

(b) Bank may collect from any Borrower even if Bank, by foreclosing on the real
property pledged as Collateral, has destroyed any right that Borrower may have
to collect from any other Borrower.

This is an unconditional and irrevocable waiver of any rights and defenses each
Borrower may have because the Indebtedness is secured by Real Property. These
rights and defenses include, but are not limited to, any rights or defenses
based upon Section 580a, 580b, 580d, or 726 of the California Code of Civil
Procedure.

<PAGE>

(8) To the fullest extent permitted by applicable law, to the extent that a
Borrower is deemed a guarantor, each Borrower expressly waives any defenses to
the enforcement of the Agreement and the other Loan Documents or any rights of
Bank created or granted hereby or to the recovery by Bank against any Borrower
or any other Person liable therefor of any deficiency after a judicial or
nonjudicial foreclosure or sale, even though such a foreclosure or sale may
impair the subrogation rights of Borrowers and may preclude Borrowers from
obtaining reimbursement or contribution from other Borrowers. To the fullest
extent permitted by applicable law, each Borrower expressly waives any
suretyship defenses or benefits that it otherwise might or would have under
applicable law. WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER
PROVISION SET FORTH IN THIS AGREEMENT, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, EACH BORROWER WAIVES ALL RIGHTS AND DEFENSES ARISING OUT OF AN
ELECTION OF REMEDIES BY BANK, EVEN THOUGH THAT ELECTION OF REMEDIES, SUCH AS A
NONJUDICIAL FORECLOSURE WITH RESPECT TO SECURITY FOR THE INDEBTEDNESS, HAS
DESTROYED SUCH BORROWER'S RIGHTS OF SUBROGATION AND REIMBURSEMENT AGAINST THE
OTHER BORROWERS BY OPERATION OF LAW, INCLUDING BUT NOT LIMITED TO SECTION 580d
OF THE CALIFORNIA CODE OF CIVIL PROCEDURE, OR OTHERWISE.

14. JURY WAIVER. THE BORROWER AND THE BANK ACKNOWLEDGE THAT THE RIGHT TO TRIAL
BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. EACH PARTY, AFTER
CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR
CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THEIR MUTUAL BENEFIT, WAIVES ANY
RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION REGARDING THE PERFORMANCE OR
ENFORCEMENT OF, OR IN ANY WAY RELATED TO, THIS AGREEMENT OR THE INDEBTEDNESS.

IN WITNESS WHEREOF, the parties have executed this Business Loan Agreement as of
the date first set forth above.

renewals and/or extensions of any of the above; all costs incurred by Bank in

any other agreement between Bank and Borrower and/or Debtor or in connection
with any proceeding involving Bank as a result of any financial accommodation to
Borrower and/or Debtor; and all other costs of collecting Indebtedness,
including without limit attorneys fees. Debtor agrees to pay Bank all such costs
incurred by the Bank, immediately upon demand, and until paid all costs shall
bear interest at the highest per annum rate applicable to any of the
Indebtedness, but not in excess of the maximum rate permitted by law. Any
reference in this Agreement to attorneys fees shall be deemed a reference to
reasonable fees, costs, and expenses of both in-house and outside counsel and
paralegals, whether inside or outside counsel is used, whether or not a suit or
action is instituted, and to court costs if a suit or action is instituted, and
whether attorneys fees or court costs are incurred at the trial court level, on
appeal, in a bankruptcy, administrative or probate proceeding or otherwise.
Debtor further covenants, agrees, represents and warrants as follows:

transaction relating to the program, and (ii) computer programs embedded in
goods and any supporting information provided in connection with a transaction
relating to the program whether or not the program is associated with the goods
in such a manner that it customarily is considered part of the goods, and
whether or not, by becoming the owner of the goods, a person acquires a right to
use the program in connection with the goods, and whether or not the program is
embedded in goods that consist solely of the medium in which the program is
embedded),

entitlements, and financial assets),

o specific items listed below and/or on attached Schedule A, if any, is/are also

cash or other property which were proceeds and are recovered by a bankruptcy
trustee or otherwise as a preferential transfer by Debtor.

In the definition of Collateral, a reference to a type of collateral shall not
be limited by a separate reference to a more specific or narrower type of that
collateral.

2. Warranties, Covenants and Agreements. Debtor warrants, covenants and agrees
as follows:

2.1 Debtor shall furnish to Bank, in form and at intervals as Bank may request,
any information Bank may reasonably request and allow Bank to examine, inspect,
and copy any of Debtor's books and records. Debtor shall, at the request of
Bank, mark its records and the Collateral to clearly indicate the security
interest of Bank under this Agreement.

2.2 At the time any Collateral becomes, or is represented to be, subject to a
security interest in favor of Bank, Debtor shall be deemed to have warranted
that: (a) Debtor is the lawful owner of the Collateral and has the right and
authority to subject it to a security interest granted to Bank; (b) none of the
Collateral is subject to any security interest other than that in favor of Bank;
(c) there are no financing statements on file, other than in favor of Bank; (d)
no person, other than Bank, has possesion or control (as defined in the Uniform
Commercial Code) of any Collateral of such nature that perfection of a security
interest may be accomplished by control; and (e) Debtor acquired its rights in
the Collateral in the ordinary course of its business.

2.3 Debtor will keep the Collateral free at all times from all claims, liens,
security interests and encumbrances other than those in favor of Bank. Debtor
will not, without the prior written consent of Bank, sell, transfer or lease, or
permit to be sold, transferred or leased, any or all of the Collateral, except
(where Inventory is pledged as Collateral) for Inventory in the ordinary course
of its business and will not return any Inventory to its supplier. Bank or its
representatives may at all reasonable times inspect the Collateral and may enter
upon all premises where the Collateral is kept or might be located.

2.4 Debtor will do all acts and will execute or cause to be executed all
writings requested by Bank to establish, maintain and continue an exclusive,
perfected and first security interest of Bank in the Collateral. Debtor agrees
that Bank has no obligation to acquire or perfect any lien on or security
interest in any asset(s), whether realty or personalty, to secure payment of the
Indebtedness, and Debtor is not relying upon assets in which the Bank may have a
lien or security interest for payment of the Indebtedness.

2.5 Debtor will pay within the time that they can be paid without interest or
penalty all taxes, assessments and similar charges which at any time are or may
become a lien, charge, or encumbrance upon any Collateral, except to the extent
contested in good faith and bonded in a manner satisfactory to Bank. If Debtor
fails to pay any of these taxes, assessments, or other charges in the time
provided above, Bank has the option (but not the obligation) to do so and Debtor
agrees to repay all amounts so expended by Bank immediately upon demand,
together with interest at the highest lawful default rate which could be charged
by Bank on any Indebtedness.

2.6 Debtor will keep the Collateral in good condition and will protect it from
loss, damage, or deterioration from any cause. Debtor has and will maintain at
all times (a) with respect to the Collateral, insurance under an "all risk"
policy against fire and other risks customarily insured against, and (b) public
liability insurance and other insurance as may be required by law or reasonably
required by Bank, all of which insurance shall be in amount, form and content,
and written by companies as may be satisfactory to Bank, containing a lender's
loss payable endorsement acceptable to Bank. Debtor will deliver to Bank
immediately upon demand evidence satisfactory to Bank that the required
insurance has been procured. If Debtor fails to maintain satisfactory insurance,
Bank has the option (but not the obligation) to do so and Debtor agrees to repay
all amounts so expended by Bank immediately upon demand, together with interest
at the highest lawful default rate which could be charged by Bank on any
Indebtedness.

<PAGE>

2.7 On each occasion on which Debtor evidences to Bank the account balances on
and the nature and extent of the Accounts Receivable, Debtor shall be deemed to
have warranted that except as otherwise indicated: (a) each of those Accounts
Receivable is valid and enforceable without performance by Debtor of any act;
(b) each of those account balances are in fact owing; (c) there are no setoffs,
recoupments, credits, contra accounts, counterclaims or defenses against any of
those Accounts Receivable; (d) as to any Accounts Receivable represented by a
note, trade acceptance, draft or other instrument or by any chattel paper or
document, the same have been endorsed and/or delivered by Debtor to Bank; (e)
Debtor has not received with respect to any Account Receivable, any notice of
the death of the related account debtor, nor of the dissolution, liquidation,
termination of existence, insolvency, business failure, appointment of a
receiver for, assignment for the benefit of creditors by, or filing of a
petition in bankruptcy by or against, the account debtor; and (f) as to each
Account Receivable, except as may be expressly permitted by Bank to the contrary
in another document, the account debtor is not an affilliate of Debtor, the
United States of America or any department, agency or instrumentality of it, or
a citizen or resident of any jurisdiction outside of the United States. Debtor
will do all acts and will execute all writings requested by Bank to perform,
enforce performance of, and collect all Accounts Receivable. Debtor shall
neither make nor permit any modification, compromise or substitution for any
Account Receivable without the prior written consent of Bank. Bank may at any
time and from time to time verify Accounts Receivable directly with account
debtors or by other methods acceptable to Bank without notifying Debtor. Debtor
agrees, at Bank's request, to arrange or cooperate with Bank in arranging for
verification of Accounts Receivable.

2.8 Debtor at all times shall be in strict compliance with all applicable laws,
including without limit any laws, ordinances, directives, orders, statutes, or
regulations an object of which is to regulate or improve health, safety, or the
environment ("Environmental laws").

2.9 If Bank, acting in its sole discretion, redelivers Collateral to Debtor or
Debtor's designee for the purpose of (a) the ultimate sale or exchange thereof;
or (b) presentation, collection, renewal, or registration of transfer thereof;
or (c) loading, unloading, storing, shipping, transshipping, manufacturing,
processing or otherwise dealing with it preliminary to sale or exchange; such
redelivery shall be in trust for the benefit of Bank and shall not constitute a
release of Bank's security interest in it or in the proceeds or products of it
unless Bank specifically so agrees in writing. If Debtor requests any such
redelivery, Debtor will deliver with such request a duly executed financing
statement in form and substance satisfactory to Bank. Any proceeds of Collateral
coming into Debtor's possession as a result of any such redelivery shall be held
in trust for Bank and immediately delivered to Bank for application on the
Indebtendess. Bank may (in its sole discretion) deliver any or all of the
Collateral to Debtor, and such delivery by Bank shall discharge Bank from all
liability or responsibilty for such Collateral. Bank, at its option, may require
delivery of any Collateral to Bank at any time with such endorsements or
assignments of the Collateral as Bank may request.

2.10 At any time and without notice, Bank may, as to Collateral other than
Equipment, Fixtures or Inventory: (a) cause any or all of such Collateral to be
transferred to its name or to the name of its nominees; (b) receive or collect
by legal proceedings or otherwise all dividends, interest, principal payments
and other sums and all other distributions at any time payable or receivable on
account of such Collateral, and hold the same as Collateral, or apply the same
to the Indebtedness, the manner and distribution of the application to be in the
sole discretion of Bank; (c) enter into any extension, subordination,
reorganization, deposit, merger or consolidation agreement or any other
agreement relating to or affecting such Collateral, and deposit or surrender
control of such Collateral, and accept other property in exchange for such
Collateral and hold or apply the property or money so received pursuant to this
Agreement; and (d) take such actions in its own name or in Debtor's name as
Bank, in its sole discretion, deems necessary or appropriate to establish
exclusive control (as defined in the Uniform Commercial Code) over any
Collateral of such nature that perfection of the Bank's security interest may be
accomplished by control.

2.11 Bank may assign any of the Indebtedness and deliver any or all of the
Collateral to its assignee, who then shall have with respect to Collateral so
delivered all the rights and powers of Bank under this Agreement, and after that
Bank shall be fully discharged from all liability and responsibility with
respect to Collateral so delivered.

2.12 Debtor delivers this Agreement based solely on Debtor's independent
investigation of (or decision not to investigate) the financial condition of
Borrower and is not relying on any information furnished by Bank. Debtor assumes
full responsibility for obtaining any further information concerning the
Borrower's financial condition, the status of the Indebtedness or any other
matter which the undersigned may deem necessary or appropriate now or later.
Debtor waives any duty on the part of Bank, and agrees that Debtor is not
relying upon nor expecting Bank to disclose to Debtor any fact now or later
known by Bank, whether relating to the operations or condition of Borrower, the
existence, liabilities or financial condition of any guarantor of the
Indebtendess, the occurrence of any default with respect to the Indebtedness, or
otherwise, notwithstanding any effect such fact may have upon Debtor's risk or
Debtor's rights against Borrower. Debtor knowingly accepts the full range of
risk encompassed in this Agreement, which risk includes without limit the
possibility that Borrower may incur Indebtedness to Bank after the financial
condition of Borrower, or Borrower's ability to pay debts as they mature, has
deteriorated.

2.13 Debtor shall defend, indemnify and hold harmless Bank, its employees,
agents, shareholders, affiliates, officers, and directors from and against any
and all claims, damages, fines, expenses, liabilites or causes of action of
whatever kind, including without limit consultant fees, legal expenses, and
attorneys fees, suffered by any of them as a direct or indirect result of any
actual or asserted violation of any law, including, without limit, Environmental
Laws, or of any remediation relating to any property required by any law,
including without limit Environmental Laws, INCLUDING ANY CLAIMS, DAMAGES,
FINES, EXPENSES, LIABILITIES OR CAUSES OF ACTION OF WHATEVER KIND RESULTING FROM
BANK'S OWN NEGLIGENCE, except and to the extent (but only to the extent) caused
by Bank's gross negligence or wilful misconduct.

3. Collection of Proceeds.

3.1 Debtor agrees to collect and enforce payment of all Collateral until Bank
shall direct Debtor to the contrary. Immediately upon notice to Debtor by Bank
and at all times after that, Debtor agrees to fully and promptly cooperate and
assist Bank in the collection and enforcement of all Collateral and to hold in
trust for Bank all payments received in connection with Collateral and from the
sale, lease or other disposition of any Collateral, all rights by way of
suretyship or guaranty and all rights in the nature of a lien or security
interest which Debtor now or later has regarding Collateral. Immediately upon
and after such notice, Debtor agrees to (a) endorse to Bank and immediately
deliver to Bank all payments received on Collateral or from the sale, lease or
other disposition of any Collateral or arising from any other rights or
interests of Debtor in the Collateral, in the form received by Debtor without
commingling with any other funds, and (b) immediately deliver to Bank all
property in Debtor's possession or later coming into Debtor's possession through
enforcement of Debtor's rights or interests in the Collateral. Debtor
irrevocably authorizes Bank or any Bank employee or agent to endorse the name of
Debtor upon any checks or other items which are received in payment for any
Collateral, and to do any and all things necessary in order to reduce these
items to money. Bank shall have no duty as to the collection or protection of
Collateral or the proceeds of it, nor as to the preservation of any related
rights, beyond the use of reasonable care in the custody and preservation of
Collateral in the possession of Bank. Debtor agrees to take all steps necessary
to preserve rights against prior parties with respect to the Collateral. Nothing
in this Section 3.1 shall be deemed a consent by Bank to any sale, lease or
other disposition of any Collateral.

3.2 Debtor agrees that immediately upon Bank's request (whether or not any Event
of Default exists) the indebtedness shall be on a "remittance basis" in
accordance with the following. In connection therewith, Debtor shall at its sole
expense establish and maintain (and Bank, at Bank's option, may establish and
maintain at Debtor's expense):

(a) A United States Post office lock box (the "Lock Box"), to which Bank shall
have exclusive access and control. Debtor expressly authorizes Bank, from time
to time, to remove contents from the Lock Box, for disposition in accordance
with this Agreement. Debtor agrees to notify all account debtors and other
parties obligated to Debtor that all payments made to Debtor (other than
payments by electronic funds transfer) shall be remitted, for the credit of
Debtor, to the Lock Box, and Debtor shall include a like statement on all
invoices; and

<PAGE>

(b) A non-interest bearing deposit account with Bank which shall be titled as
designated by Bank (the "Cash Collateral Account") to which Bank shall have
exclusive access and control. Debtor agrees to notify all account debtors and
other parties obligated to Debtor that all payments made to Debtor by electronic
funds transfer shall be remitted to the Cash Collateral Account, and Debtor, at
Bank's request, shall include a like statement on all invoices. Debtor shall
execute all documents and authorizations as required by Bank to establish and
maintain the Lock Box and the Cash Collateral Account.

3.3 All items or amounts which are remitted to the Lock Box, to the Cash
Collateral Account, or otherwise delivered by or for the benefit of Debtor to
Bank on account of partial or full payment of, or with respect to, any
Collateral shall, at Bank's option, (a) be applied to the payment of the
Indebtedness, whether then due or not, in such order or at such time of
application as Bank may determine in its sole discretion, or, (b) be deposited
to the Cash Collateral Account. Debtor agrees that Bank shall not be liable for
any loss or damage which Debtor may suffer as a result of Bank's processing of
items or its exercise of any other rights or remedies under this Agreement,
including without limitation indirect, special or consequential damages, loss of
revenues or profits, or any claim, demand or action by any third party arising
out of or in connection with the processing of items or the exercise of any
other rights or remedies under this Agreement. Debtor agrees to indemnify and
hold Bank harmless from and against all such third party claims, demands or
actions, and all related expenses or liabilities, including, without limitation,
attorney's fees and INCLUDING CLAIMS, DAMAGES, FINES, EXPENSES, LIABILITIES OR
CAUSES OF ACTION OF WHATEVER KIND RESULTING FROM BANK'S OWN NEGLIGENCE except to
the extent (but only to the extent) caused by Bank's gross negligence or willful
misconduct.

4. Defaults, Enforcement and Application of Proceeds.

4.1 Upon the occurrence of any of the following events (each an "Event of
Default"), Debtor shall be in default under this Agreement:

(a) Any failure to pay the Indebtedness or any other indebtedness when due, or
such portion of it as may be due, by acceleration or otherwise; or

(b) Any failure or neglect to comply with, or breach of or default under, any
term of this Agreement, or any other agreement or commitment between Borrower,
Debtor, or any guarantor of any of the Indebtedness ("Guarantor") and Bank; or

(c) Any warranty, representation, financial statement, or other information
made, given or furnished to Bank by or on behalf of Borrower, Debtor, or any
Guarantor shall be, or shall prove to have been, false or materially misleading
when made, given, or furnished; or

(d) Any loss, theft, substantial damage or destruction to or of any Collateral,
or the issuance or filing of any attachment, levy, garnishment or the
commencement of any proceeding in connection with any Collateral or of any other
judicial process of, upon or in respect of Borrower, Debtor, any Guarantor, or
any Collateral; or

(e) Sale or other disposition by Borrower, Debtor, or any Guarantor of any
substantial portion of its assets or property or voluntary suspension of the
transaction of business by Borrower, Debtor, or any Guarantor, or death,
dissolution, termination of existence, merger, consolidation, insolvency,
business failure, or assignment for the benefit of creditors of or by Borrower,
Debtor, or any Guarantor; or commencement of any proceedings under any state or
federal bankruptcy or insolvency laws or laws for the relief of debtors by or
against Borrower, Debtor, or any Guarantor; or the appointment of a receiver,
trustee, court appointee, sequestrator or otherwise, for all or any part of the
property of Borrower, Debtor, or any Guarantor; or

(f) Bank deems the margin of Collateral insufficient or itself insecure, in good
faith believing that the prospect of payment of the Indebtedness or performance
of this Agreement is impaired or shall fear deterioration, removal, or waste of
Collateral; or

(g) An event of default shall occur under any instrument, agreement or other
document evidencing, securing or otherwise relating to any of the Indebtedness.

4.2 Upon the occurrence of any Event of Default, Bank may at its discretion and
without prior notice to Debtor declare any or all of the Indebtedness to be
immediately due and payable, and shall have and may exercise any right or remedy
available to it including, without limitation, any one or more of the following
rights and remedies:

(a) Exercise all the rights and remedies upon default, in foreclosure and
otherwise, available to secured parties under the provisions of the Uniform
Commercial Code and other applicable law;

(b) Institute legal proceedings to foreclose upon the lien and security interest
granted by this Agreement; to recover judgment for all amounts then due and
owing as Indebtedness, and to collect the same out of any Collateral or the
proceeds of any sale of it;

(c) Institute legal proceedings for the sale, under the judgment or decree of
any court of competent jurisdiction, of any or all Collateral; and/or

(d) Personally or by agents, attorneys, or appointment of a receiver, enter upon
any premises where Collateral may then be located, and take possession of all or
any of it and/or render it unusable; and without being responsible for loss or
damage to such Collateral, hold, operate, sell, lease, or dispose of all or any
Collateral at one or more public or private sales, leasings or other
dispositions, at places and times and on terms and conditions as Bank may deem
fit, without any previous demand or advertisement; and except as provided in
this Agreement, all notice of sale, lease or other disposition, and
advertisement, and other notice or demand, any right or equity of redemption,
and any obligation of a prospective purchaser or lessee to inquire as to the
power and authority of Bank to sell, lease, or otherwise dispose of the
Collateral or as to the application by Bank of the proceeds of sale or
otherwise, which would otherwise be required by, or available to Debtor under,
applicable law are expressly waived by Debtor to the fullest extent permitted.

At any sale pursuant to this Section 4.2, whether under the power of sale, by
virtue of judicial proceedings or otherwise, it shall not be necessary for Bank
or a public officer under order of a court to have present physical or
constructive possession of Collateral to be sold. The recitals contained in any
conveyances and receipts made and given by Bank or the public officer to any
purchaser at any sale made pursuant to this Agreement shall, to the extent
permitted by applicable law, conclusively establish the truth and accuracy of
the matters stated (including, without limit, as to the amounts of the principal
of and interest on the Indebtedness, the accrual and nonpayment of it and
advertisement and conduct of the sale); and all prerequisites to the sale shall
be presumed to have been satisfied and performed. Upon any sale of any
Collateral, the receipt of the officer making the sale under judicial
proceedings or of Bank shall be sufficient discharge to the purchaser for the
purchase money, and the purchaser shall not be obligated to see to the
application of the money. Any sale of any Collateral under this Agreement shall
be a perpetual bar against Debtor with respect to that Collateral. At any sale
or other disposition of the Collateral pursuant to this Section 4.2, Bank
disclaims all warranties which would otherwise be given under the Uniform
Commercial Code, including without limit a disclaimer of any warranty relating
to title, possesion, quiet enjoyment or the like, and Bank may communicate these
disclaimers to a purchaser at such disposition. This disclaimer of warranties
will not render the sale commercially unreasonable.

4.3 Debtor shall at the request of Bank, notify the account debtors or obligors
of Bank's security interest in the Collateral and direct payment of it to Bank.
Bank may, itself, upon the occurrence of any Event of Default so notify and
direct any account debtor or obligor. At the request of Bank, whether or not an
Event of Default shall have occurred, Debtor shall immediately take such actions
as the Bank shall request to establish exclusive control (as defined in the
Uniform Commercial Code) by Bank over any Collateral which is of such a nature
that perfection of a security interest may be accomplished by control.

<PAGE>

4.4 The proceeds of any sale or other disposition of Collateral authorized by
this Agreement shall be applied by Bank first upon all expenses authorized by
the Uniform Commercial Code and all reasonable attorney fees and legal expenses
incurred by Bank; the balance of the proceeds of the sale or other disposition
shall be applied in the payment of the Indebtedness, first to interest, then to
principal, then to remaining Indebtedness and the surplus, if any, shall be paid
over to Debtor or to such other person(s) as may be entitled to it under
applicable law. Debtor shall remain liable for any deficiency, which it shall
pay to Bank immediately upon demand. Debtor agrees that Secured Party shall be
under no obligation to accept any noncash proceeds in connection with any sale
or disposition of Collateral unless failure to do so would be commercially
unreasonable. If Secured Party agrees in its sole discretion to accept noncash
proceeds (unless the failure to do so would be commercially unreasonable),
Secured Party may ascribe any commercially reasonable value to such proceeds.
Without limiting the foregoing, Secured Party may apply any discount factor in
determining the present value of proceeds to be received in the future or may
elect to apply proceeds to be received in the future only as and when such
proceeds are actually received in cash by Secured Party.

4.5 Nothing in this Agreement is intended, nor shall it be construed, to
preclude Bank from pursuing any other remedy provided by law or in equity for
the collection of the Indebtedness or for the recovery of any other sum to which
Bank may be entitled for the breach of this Agreement by Debtor. Nothing in this
Agreement shall reduce or release in any way any rights or security interests of
Bank contained in any existing agreement between Borrower, Debtor, or any
Guarantor and Bank.

4.6 No waiver of default or consent to any act by Debtor shall be effective
unless in writing and signed by an authorized officer of Bank. No waiver of any
default or forbearance on the part of Bank in enforcing any of its rights under
this Agreement shall operate as a waiver of any other default or of the same
default on a future occasion or of any rights.

4.7 Debtor (a) irrevocably appoints Bank or any agent of Bank (which appointment
is coupled with an interest) the true and lawful attorney of Debtor (with full
power of substitution) in the name, place and stead of, and at the expense of,
Debtor and (b) authorizes Bank or any agent of Bank, in its own name, at
Debtor's expense, to do any of the following, as Bank, in its sole discretion,
deems appropriate:

(i) to demand, receive, sue for, and give receipts or acquittances for any
moneys due or to become due on any Collateral and to endorse any item
representing any payment on or proceeds of the Collateral;

(ii) to execute and file in the name of and on behalf of Debtor all financing
statements or other filings deemed necessary or desirable by Bank to evidence,
perfect, or continue the security interests granted in this Agreement; and

(iii) to do and perform any act on behalf of Debtor permitted or required under
this Agreement.

4.8 Upon the occurrence of an Event of Default, Debtor also agrees, upon request
of Bank, to assemble the Collateral and make it available to Bank at any place
designated by Bank which is reasonably convenient to Bank and Debtor.

4.9 The following shall be the basis for any finder of fact's determination of
the value of any Collateral which is the subject matter of a disposition giving
rise to a calculation of any surplus or deficiency under Section 9.615(f) of the
Uniform Commercial Code (as in effect on or after July 1, 2001): (a) The
Collateral which is the subject matter of the disposition shall be valued in an
"as is" condition as of the date of the disposition, without any assumption or
expectation that such Collateral will be repaired or improved in any manner; (b)
the valuation shall be based upon an assumption that the transferee of such
Collateral desires a resale of the Collateral for cash promptly (but no later
then 30 days) following the disposition; (c) all reasonable closing costs
customarily borne by the seller in commercial sales transactions relating to
property similar to such Collateral shall be deducted including, without
limitation, brokerage commissions, tax prorations, attorney's fees, whether
inside or outside counsel is used, and marketing costs; (d) the value of the
Collateral which is the subject matter of the disposition shall be further
discounted to account for any estimated holding costs associated with
maintaining such Collateral pending sale (to the extent not accounted for in (c)
above), and other maintenance, operational and ownership expenses; and (e) any
expert opinion testimony given or considered in connection with a determination
of the value of such Collateral must be given by persons having at least 5 years
experience in appraising property similar to the Collateral and who have
conducted and prepared a complete written appraisal of such Collateral taking
into consideration the factors set forth above. The "value" of any such
Collateral shall be a factor in determining the amount of proceeds which would
have been realized in a disposition to a transferee other than a secured party,
a person related to a secured party or a secondary obligor under Section
9.615(f) of the Uniform Commerical Code.

5. Miscellaneous.

5.1 Until Bank is advised in writing by Debtor to the contrary, all notices,
requests and demands required under this Agreement or by law shall be given to,

5.2 Debtor will give Bank not less than 90 days prior written notice of all
contemplated changes in Debtor's name, location, chief executive office,
principal place of business, and/or location of any Collateral, but the giving
of this notice shall not cure any Event of Default caused by this change.

5.3 Bank assumes no duty of performance or other responsibility under any
contracts contained within the Collateral.

5.4 Bank has the right to sell, assign, transfer, negotiate or grant
participations or any interest in, any or all of the Indebtedness and any
related obligations, including without limit this Agreement. In connection with
the above, but without limiting its ability to make other disclosures to the
full extent allowable, Bank may disclose all documents and information which
Bank now or later has relating to Debtor, the Indebtedness or this Agreement,
however obtained. Debtor further agrees that Bank may provide information
relating to this Agreement or relating to Debtor or the Indebtedness to the
Bank's parent, affiliates, subsidiaries, and service providers.

5.5 In addition to Bank's other rights, any indebtedness owing from Bank to
Debtor can be set off and applied by Bank on any Indebtedness at any time(s)
either before or after maturity or demand without notice to anyone. Any such
action shall not constitute acceptance of collateral in discharge of any portion
of the Indebtedness.

5.6 Debtor, to the extent not expressly prohibited by applicable law, waives any
right to require the Bank to: (a) proceed against any person or property; (b)
give notice of the terms, time and place of any public or private sale of
personal property security held from Borrower or any other person or otherwise
comply with the provisions of Section 9.504 of the Uniform Commercial Code in
effect prior to July 1, 2001 or its successor provisions thereafter; or (c)
pursue any other remedy in the Bank's power. Debtor waives notice of acceptance
of this Agreement and presentment, demand, protest, notice of protest, dishonor,
notice of dishonor, notice of default, notice of intent to accelerate or demand
payment of any Indebtedness, any and all other notices to which the undersigned
might otherwise be entitled, and diligence in collecting any Indebtedness, and
agree(s) that the Bank may, once or any number of times, modify the terms of any
Indebtedness, compromise, extend, increase, accelerate, renew or forbear to
enforce payment of any or all Indebtedness, or permit Borrower to incur
additional Indebtedness, all without notice to Debtor and

<PAGE>

without affecting in any manner the unconditional obligation of Debtor under
this Agreement. Debtor unconditionally and irrevocably waives each and every
defense and setoff of any nature which, under principles of guaranty or
otherwise, would operate to impair or diminish in any way the obligation of
Debtor under this Agreement, and acknowledges that such waiver is by this
reference incorporated into each security agreement, collateral assignment,
pledge and/or other document from Debtor now or later securing the Indebtedness,
and acknowledges that as of the date of this Agreement no such defense or setoff
exists.

5.7 Debtor waives any and all rights (whether by subrogation, indemnity,
reimbursement, or otherwise) to recover from Borrower any amounts paid or the
value of any Collateral given by Debtor pursuant to this Agreement until such
time as all of the Indebtedness has been fully paid.

5.8 In the event that applicable law shall obligate Bank to give prior notice to
Debtor of any action to be taken under this Agreement, Debtor agrees that a
written notice given to Debtor at least ten days before the date of the act
shall be reasonable notice of the act and, specifically, reasonable notification
of the time and place of any public sale or of the time after which any private
sale, lease, or other dispostion is to be made, unless a shorter notice period
is reasonable under the circumstances. A notice shall be deemed to be given
under this Agreement when delivered to Debtor or when placed in an envelope
addressed to Debtor and deposited, with postage prepaid, in a post office or
official depository under the exclusive care and custody of the United States
Postal Service or delivered to an overnight courier. The mailing shall be by
overnight courier, certified, or first class mail.

5.9 Notwithstanding any prior revocation, termination, surrender, or discharge
of this Agreement in whole or in part, the effectiveness of this Agreement shall
automatically continue or be reinstated in the event that any payment received
or credit given by Bank in respect of the Indebtedness is returned, disgorged,
or rescinded under any applicable law, including, without limitation, bankruptcy
or insolvency laws, in which case this Agreement, shall be enforceable against
Debtor as if the returned, disgorged, or rescinded payment or credit had not
been received or given by Bank, and whether or not Bank relied upon this payment
or credit or changed its position as a consequence of it. In the event of
continuation or reinstatement of this Agreement, Debtor agrees upon demand by
Bank to execute and deliver to Bank those documents which Bank determines are
appropriate to further evidence (in the public records or otherwise) this
continuation or reinstatement, although the failure of Debtor to do so shall not
affect in any way the reinstatement or continuatuion.

5.10 This Agreement and all the rights and remedies of Bank under this Agreement
shall inure to the benefit of Bank's successors and assigns and to any other
holder who derives from Bank title to or an interest in the Indebtedness or any
portion of it, and shall bind Debtor and the heirs, legal representatives,
successors, and assigns of Debtor. Nothing in this Section 5.10 is deemed a
consent by Bank to any assignment by Debtor.

5.11 If there is more then one Debtor, all undertakings, warranties and
covenants made by Debtor and all rights, powers and authorities given to or
conferred upon Bank are made or given jointly and severally.

5.12 Except as otherwise provided in this Agreement, all terms in this Agreement
have the meanings assigned to them in Division 9 (or, absent definition in
Division 9, in any other Division) of the Uniform Commercial Code, as those
meanings may be amended, supplemented, revised or replaced from time to time.
"Uniform Commercial Code" means the California Uniform Commercial Code, as
amended, supplemented, revised or replaced from time to time. Notwithstanding
the foregoing, the parties intend that the terms used herein which are defined
in the Uniform Commercial Code have, at all times, the broadest and most
inclusive meanings possible. Accordingly, if the Uniform Commercial code shall
in the future be amended or held by a court to define any term used herein more
broadly or inclusively than the Uniform Commercial Code in effect on the date of
this Agreement, then such term, as used herein, shall be given such broadened
meaning. If the Uniform Commercial Code shall in the future be amended or held
by a court to define any term used herein more narrowly, or less inclusively,
then the Uniform Commercial Code in effect on the date of this Agreement, such
amendment or holding shall be disregarded in defining terms used in this
Agreement.

5.13 No single or partial exercise, or delay in the exercise, of any right or
power under this Agreement, shall preclude other or further exercise of the
rights and powers under this Agreement. The unenforceability of any provision of
this Agreement shall not affect the enforceability of the remainder of this
Agreement. This Agreement constitutes the entire agreement of Debtor and Bank
with respect to the subject matter of this Agreement. No amendment or
modification of this Agreement shall be effective unless the same shall be in
writing and signed by Debtor and an authorized officer of Bank. THIS AGREEMENT
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE
STATE OF CALIFORNIA, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPALS.

5.14 To the extent that any of the Indebtedness is payable upon demand, nothing
contained in this Agreement shall modify the terms and conditions of that
Indebtedness nor shall anything contained in this Agreement prevent Bank from
making demand, without notice and with or without reason, for immediate payment
of any or all of that Indebtedness at any time(s), whether or not an Event of
Default has occurred.

                                ADDRESS

This ENVIRONMENTAL RIDER (this "Rider") dated this 8th day of September , 2003

1. Borrower hereby represents, warrants and covenants that none of the
collateral or real property occupied and/or owned by Borrower has ever been used
by Borrower or any other previous owner and/or operator in connection with the
disposal of or to refine, generate, manufacture, produce, store, handle, treat,
transfer, release, process or transport any hazardous waste, as defined in 42
U.S.C. 9601 (14) ("Hazardous Substance"), and Borrower will not at any time use
the collateral or such real property for the disposal of, refining of,
generating, manufacturing, producing, storing, handling, treating, transferring,
releasing, processing, or transporting any such Hazardous Waste and/or Hazardous
Substances.

2. None of the collateral or real property used and/or occupied by Borrower has
been designated, listed or identified in any manner by the United States
Environmental Protection Agency (the "EPA") or under and pursuant to the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended, set forth at 42 U.S.C. 9601 et seq. ("CERCLA") or the Resource

     This Amendment Number Two to Loan and Security Agreement (“Amendment”) is
entered into as of March 17, 2003, by and between COMERICA BANK – CALIFORNIA
(“Bank”) and ASYST TECHNOLOGIES, INC., a California corporation (“Borrower”),
in light of the following:

     A.      Borrower and Bank have previously entered into that certain Loan and
Security Agreement, dated as of October 1, 2002 (as amended from time to time,
the “Loan Agreement”).

     B.      In connection with the Loan Agreement, Borrower and Bank have entered
into various other agreements (such agreements, together with the Loan
Agreement, are collectively referred to herein as the “Loan Documents”).

     C.      Borrower and Bank desire to amend the Loan Agreement as provided for
and on the conditions herein.

     NOW, THEREFORE, Borrower and Bank hereby amend and supplement the Loan
Agreement as follows:

     1.      DEFINITIONS. All initially capitalized terms used in this Amendment
shall have the meanings given to them in the Loan Agreement unless specifically
defined herein.

     2.      AMENDMENTS.

          (a)      Section 6.7(c) of the Loan Agreement is hereby amended and restated in
its entirety to read as follows:

               (c)      Minimum Liquidity. Maintain as March 17, 2003 and at all
times thereafter a balance of unrestricted cash and cash
equivalents held in the United States of at least $40,000,000, of
which at least $25,000,000, as of March 17, 2003 and at all times
thereafter, shall be held in a money market investment account
maintained at Bank, and measured monthly and reported in the
Borrowing Base Certificate delivered in compliance with Section
6.2(a).

          (b)      The definition of “Borrowing Base” set forth in Exhibit A to the Loan
Agreement is hereby amended and restated in its entirety, and shall be
effective retroactively as of January 30, 2003, to read as follows:

               “Borrowing Base” means, as to Advances outstanding at any
time in an aggregate amount in excess of $16,500,000 (in excess of
$7,000,000 from and after September 30, 2003), an amount equal to
80% of Eligible Accounts and Eligible Foreign Accounts, as
determined by Bank with reference to the most recent Borrowing
Base Certificate delivered by Borrower; provided that up to

1.

 

$16,500,000 (up to $7,000,000 from and after September 30, 2003)
of Advances in the aggregate may be outstanding at any time
without regard to the amount of Eligible Accounts or Eligible
Foreign Accounts (but such “non-formula” Advances shall be deemed
to be within the Borrowing Base for the purposes of this
Agreement); provided further that, effective from January 30, 2003
through September 30, 2003 only, the Borrowing Base shall also
include an amount equal to 50% of Specified Eligible Foreign
Accounts (and the amount, before application of such 50% advance
rate, of such Specified Eligible Foreign Accounts shall be limited
to $2,000,000 in the aggregate at any time).

all of Borrower’s representations and warranties set forth in the Loan
Agreement are true, complete and accurate in all material respects as of the
date hereof.

has occurred and is continuing as of the date hereof.

     5.      CONDITION PRECEDENT. The effectiveness of this Amendment is expressly
conditioned upon the receipt by Bank of an executed copy of this Amendment.

     6.      COSTS AND EXPENSES. Borrower shall pay to Bank all of Bank’s
out-of-pocket costs and expenses (including, without limitation, the reasonable
fees and expenses of its counsel, which counsel may include any local counsel
deemed necessary, search fees, filing and recording fees, documentation fees,
appraisal fees, travel expenses, and other fees) arising in connection with the
preparation, execution, and delivery of this Amendment and all related
documents.

     7.      LIMITED EFFECT. In the event of a conflict between the terms and
provisions of this Amendment and the terms and provisions of the Loan
Agreement, the terms and provisions of this Amendment shall govern. In all
other respects, the Loan Agreement, as amended and supplemented hereby, shall
remain in full force and effect.

     8.      COUNTERPARTS; EFFECTIVENESS. This Amendment may be executed in any
number of counterparts and by different parties on separate counterparts, each
of which when so executed and delivered shall be deemed to be an original. All
