Upon the effective date of the restructure (as defined below) the Shares shall be canceled by Headwaters and all rights of Larson and/or Larson Holdings thereunder shall be forever relinquished. 1 (c) A new Promissory Note in the original principal amount of $1,750,000 (the "Restructured Note") in the form attached hereto as Exhibit "A" signed by Larson and guaranteed by Larson Holdings.
