Any failure or delay of Dr. Vogt to exercise any right hereunder shall not be construed as a waiver of the right to exercise the same or any other right at any other time.

The provisions of this Note are severable, and the invalidity or unenforceability of any provision shall not alter or impair the remaining provisions of this Note. 8.) All payments due to Dr. Vogt will be made without set-off or counterclaim, free and clear of any deduction or withholding on account of any present or future taxes, duties, or other charges imposed by Switzerland or the United States of America or any political subdivision or taxing authority thereof or therein (other than taxes imposed on or measured by the net income of Dr. Vogt ("Taxes")), all of which will be for the account of Maker and paid by it when due. The Maker will indemnify and reimburse Dr. Vogt on demand for any deduction or withholding of Taxes and interest and penalties thereon, and the Maker will pay such additional amount as will result in the receipt by Dr. Vogt, after such deduction or withholding, of an amount equal to the amount that would have been received if such deduction or withholding had not been required. If the Maker pay any Tax, interest, or penalties, as provided in this Note or makes any deduction or withholding from amounts paid under this Note, Maker will forthwith forward to Dr. Vogt official receipts or other evidence establishing payment of such amount. The provisions of this paragraph including, without limitation, the Maker's agreement to indemnify or reimburse, will survive the termination of this Note or the complete repayment of this Note (whichever occurs first) for a period of seven years. 9.)

No payment of principal shall be made on this Note unless the principal and all interest on the Senior Debt has been indefeasibly made.

No principal or interest shall be made on this Note at any time that there exists a default (or event which with the giving of notice or the lapse of time will constitute a default) on the Senior Debt. If any payments are made to the holder of this Note in contravention of the terms of this Section 9, the holder of this Note will immediately pay such amounts received over to the holders of the Senior Debt. Nothing shall impair, as between the Maker and the holder of this Note, the obligations of the Maker to pay the holder of this Note all amounts payable under this Note. The holder of this Note may not accelerate this Note pursuant to Section 4 due to any delays in the payment of interest or principal on this Note pursuant to the operation of this Section 9. 10.)
