payment based upon a ten (10) year amortization, that this loan is all due and
payable in five (5) years, and that the final payment will be a substantial
balloon payment representing the majority of the principal balance of this loan.

by applying the ratio of the annual interest rate in effect over 365 days in a
year, times the outstanding
<PAGE>

principal balance, times the actual number of days the principal balance is
outstanding. Borrower will pay Lender at 2600W. Magnolia Blvd., Burbank, CA

otherwise agreed or required by applicable law, payments will be applied first
to any unpaid collection costs and late charges, then to unpaid interest, and

          ----------------------

Journal which is hereinafter referred to as the "Index". If the Index becomes
-------
unavailable during the term of this loan, Lender may designate a similar
substitute index after notice to Borrower. Lender will tell Borrower the current
index rate upon Borrower's request. The Index is currently 9.5 percent per
annum. On July 1, 2001, and on July 1, of each year thereafter, the variable
interest rate will be changed as set forth herein. The interest rate to be
applied to the unpaid principal balance of this Note shall be equal to the Index
in effect, as of each Payment Change Date. This rate will be in effect until the

Note be more than the maximum rate allowed by applicable law.

<PAGE>

payment, or otherwise, shall be credited pro-rata to each of the obligations
listed above and Borrower shall not have the right to specify any alteration of
the foregoing allocation. The listing of the sums set forth above in paragraphs
b. through u., inclusive, is a restatement, ratification, and assumption of such
obligations, and their restatement, herein, shall not result in full payment or
satisfaction of the obligations referenced nor shall it be construed as creating
a new separate and distinct obligation of the entity whose obligation is
referenced in paragraphs b through u, inclusive, above. Rather, the referenced
obligations shall be deemed paid or satisfied only, to the extent payments are
actually made to Lender, and allocated, as set forth above, and no double
liability shall be imposed on any entity referenced in paragraphs b through u,
above.

         -----------------------------
Lender, herein, shall determine among themselves the proper distribution of

         -----------
the amount owed earlier than it is due. However, any such payment shall be
allocated as set forth in paragraph 4, above. Early payments will not, unless

continue making payments under the payment schedule. Rather, they will reduce
the principal balance due.

     7.  Late Charge.  If a payment is ten (10) days or more late, Borrower
         -----------
will be charged- five percent (5%) of the regularly scheduled payment as a late
charge.

         ---------------
hereunder, in making any payment hereunder, or performing any other obligation
or condition provided for hereunder, or contained in any other agreement of
Borrower with Lender, or any default as defined in Paragraph 10, below, Lender
may, at its option, declare the entire unpaid principal balance of this Note and
all accrued unpaid interest immediately due, without notice, and then Borrower
will pay that amount. Upon Borrower's failure to pay all amounts declared due
pursuant to this section, including failure to pay upon final maturity, Lender,
at its option, may also, if permitted under applicable law, increase the
interest rate otherwise chargeable pursuant to this Note, by five (5) percentage
points per annum. Lender may hire or pay someone else to help collect this Note
if Borrower does not pay. Borrower also
<PAGE>

will pay Lender that amount. This includes, subject to any limits under
applicable law, Lender's reasonable attorneys' fees and legal expenses, whether
or not there is a lawsuit, including reasonable attorneys' fees and legal
expenses for bankruptcy proceedings (including efforts to modify or vacate any
automatic stay or injunction), appeals, and any anticipated post-judgment
collection services. Borrower also will pay any court costs, in addition to all
other sums provided by law. This Note has been delivered to Lender and accepted
by Lender in the State of California, County of Los Angeles. If there is a
