         Event of Default (other than specified in Section 10.01(d)) hereof
         shall have occurred and be continuing;

         provided further that, notwithstanding the foregoing provisions of

   4
         Payments made at any time during the period of four consecutive fiscal
         quarters of the Company ending with the fiscal quarter during which
         such date falls, provided that, for purposes of this clause (v)
         Dividend Payments shall exclude (x) redemptions by the Company of a
         portion of its common stock for cash paid by the Company in an
         aggregate amount up to but not exceeding $5,000,000 in connection with
