                                    DEMAND PROMISSORY NOTE

$32,060,887                                                   December 31, 1997

FOR VALUE RECEIVED AND FOR THE PURPOSE OF CONSOLIDATING THE INDEBTEDNESS LISTED 
ON THE ATTACHED EXHIBIT B,  the undersigned promises to pay to E. Khashoggi 
Industries or order, the principal amount of Thirty-two Million Sixty 
Thousand Eight Hundred Eighty-seven Dollars ($32,060,887), together with 
interest from date hereof at the initial rate of Eight and One-Half percent 
(8.50%) per annum which represents the Prime Rate (as defined below) on 
September 30, 1997, on the unpaid balance, payable in lawful money of the 
United States of America at the office of E. Khashoggi Industries without 
defalcation or discount. The interest rate shall be adjusted to the Prime 
Rate in effect on the first day of each calendar quarter (January 1, April 1, 
July 1 and October 1) commencing January 1, 1998. The term "Prime Rate" means 
the highest "Prime Rate" as published in the Wall Street Journal's "Money 
Rates" table, which is described as the base rate on the corporate loans at 
large US money center banks. Interest shall be compounded quarterly and paid 
at the last day of each calendar quarter commencing on December 31, 1997. The 
unpaid principal balance, and any accrued but unpaid interest, shall be 
payable upon demand and in all events shall be due and payable on December 
31, 2000. Any Interest not paid when due shall be added to the principal 
balance. Unless otherwise provided herein, all payments hereunder shall be 
applied first to accrued interest and the balance to the reduction of 
principal. Any portion of principal or interest not paid when due shall 
continue to bear interest as stipulated above until paid.

In case of default in the payment of principal or interest hereunder, 
proceedings may at once be instituted for the recovery of the same, and the 
undersigned agrees to pay all costs of such proceedings and any other costs 
of collection, including reasonable attorney's fees.

The undersigned may pay this Note in part or in full without penalty.

The undersigned severally waive presentment, protest and demand; and waive 
notice of protest, demand and of dishonor and non-payment of this Note, and 
expressly agrees that this Note, or any payment thereunder, may be extended 
from time to time without in any way effecting the liability of the 
undersigned.

Upon due execution and delivery of this Note, E. Khashoggi Industries will 
deliver to the undersigned any promissory notes or other written obligations 
evidencing the indebtedness listed in the attached Exhibit B, marked "canceled".
