$1,000,000.00     November 13, 2000     ON DEMAND              77-0524421
--------------------------------------------------------------------------------

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, One 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 plus 0.000% 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 13th day of each month commencing December 13, 2000. 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 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

discharge. The undersigned agree(s) that the Bank has the right to sell, assign,

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

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.
