                                    NOTE


$6,000,000.00          Beverly Hills, California            August 7, 1997

On November 3, 2002, and as hereinafter provided, for value received, the 
undersigned promises to pay to IMPERIAL BANK ("Bank"), a California banking 
corporation, or order, at its Financial Services Group office, the principal 
sum of $6,000,000.00 or such sums up to the maximum if so stated, as the Bank 
may now or hereafter advance to or for the benefit of the undersigned in 
accordance with the terms hereof, together with interest from date of 
disbursement or N/A, whichever is later, on the unpaid principal balance / / 
at the rate of     % per year /X/ at the rate of 0.000% per year in excess of 
the rate of interest which Bank has announced as its prime lending rate (the 
"Prime Rate"), which shall vary concurrently with any change in such Prime 
Rate, or $250.00, whichever is greater. Interest shall be computed at the 
above rate on the basis of the actual number of days during which the 
principal balance is outstanding, divided by 360, which shall, for interest 
computation purposes, be considered one year.

Interest shall be payable /X/ monthly / / quarterly / / included with 
principal /X/ in addition to principal / / beginning September 3, 1997, and 
if not so paid shall become a part of the principal. All payments shall be 
applied first to interest, and the remainder, if any, on principal, /X/ (if 
checked), Principal shall be payable in installments of $33,334.00, or more, 
each installment on the 3rd day of each month, beginning May 3, 1998. Advances
not to exceed any unpaid balance owing at any one time equal to the maximum 
amount specified above, may be made at the option of Bank.

     Any partial prepayment shall be applied to the installments, if any, in 
inverse order of maturity. Should default be made in the payment of principal 
or interest when due, or in the performance or observance, when due, of any 
item, covenant or condition of any deed or trust, security agreement or other 
agreement (including amendments or extensions thereof) securing or pertaining 
to this note, at the option of the holder hereof and without notice of demand, 
the entire balance of principal and accrued interest then remaining unpaid 
shall (a) become immediately due and payable, and (b) thereafter bear 
interest, until paid in full, at the increased rate of 5% per year in excess 
of the rate provided for above, as it may vary from time to time.

     Defaults shall include, but not be limited to, the failure of the 
maker(s) to pay principal or interest when due; the filing as to each person 
obligated hereon, whether as maker, co-maker, endorser or guarantor 
(individually or collectively referred to as the "Obligor") of a voluntary or 
involuntary petition under the provisions of the Federal Bankruptcy Act; the 
issuance of any attachment or execution against any asset of any Obligor; the 
death of any Obligor; or any deterioration of the financial condition of any 
Obligor which results in the holder hereof considering itself, in good faith, 
insecure.

/X/ If any installment payment or principal balance payment due hereunder is 
delinquent ten or more days, Obligor agrees to pay a late charge in the 
amount of 5% of the payment so due and unpaid, in addition to the payment; 
but nothing in this paragraph is to be construed as any obligation on the 
part of the holder of this note to accept payment of any installment past due 
or less than the total unpaid principal balance after maturity.

     If this note is not paid when due, each Obligor promises to pay all 
costs and expenses of collection and reasonable attorney's fees incurred by 
the holder hereof on account of such collection, plus interest at the rate 
applicable to principal, whether or not suit is filed hereon. Each Obligor 
shall be jointly and severally liable hereon and consents to renewals, 
replacements and extensions of time for payment hereof, before, at, or after 
maturity; consents to the acceptance, release or substitution of security for 
this note; and waives demand and protest and the right to assert any statute 
of limitations. Any married person who signs this note agrees that recourse 
may be had against separate property for any obligations hereunder. The 
indebtedness evidenced hereby shall be payable in lawful money of the United 
States. In any action brought under or arising out of this note, each 
Obligor, including successor(s) or assign(s) hereby consents to the 
application of California law, to the jurisdiction of any competent court 
within the State of California, and to service of process by any means 
authorized by California law

     No single or partial exercise of any power hereunder, or under any deed 
of trust, security agreement or other agreement in connection herewith shall 
preclude other or further exercises thereof or the exercise of any other such 
power. The holder hereof shall at all times have the right to proceed against 
any portion of the security for this note in such order and in such manner as 
such holder may consider appropriate, without waiving any rights with respect 
to any of the security. Any delay or omission on the part of the holder 
hereof in exercising any right hereunder, or under any deed of trust, 
security agreement or other agreement, shall not operate as a waiver of such 
right, or of any other right, under this note or any deed of trust, security 
agreement or other agreement in connection herewith.
