Payment/Prepayment. (a) This Note may be prepaid at any time, in whole or in part, without penalty or premium. Each partial prepayment shall be applied first to the Interest and then to the Principal Amount. This Note is a full recourse note secured by the Property (as defined in Section 2 below). (b) This Note will be funded by the date of the closing of the purchase of the Property (as defined below) (the "Loan Date"). Unless paid sooner, the Principal Amount plus Interest shall be due and payable to SCI, LLC on the earlier of (x) the fifth anniversary of the Loan Date or (y) no later than 90 days after the termination of Thorburn's employment with SCI, LLC, or its Parent (as such term is defined in Thorburn's Employment Agreement with SCI, LLC) or subsidiaries for any reason. In the event Thorburn is actively employed with SCI, LLC, or its Parent or subsidiaries on the fifth anniversary of the Loan Date, the Board of Directors of SCG Holding Corporation (the "Board") may consider (1) forgiving up to 50% of the Principal Amount and/or Interest if SCG Holding Corporation ("Holding") achieves the established Market Share Target (described in Appendix I hereto) for the five-year period ended on the last day of the fiscal quarter immediately preceding the fifth anniversary of the Loan Date, and (2) forgiving up to 50% of the Principal Amount and/or Interest if Holding achieves the established Gross Margin Percentage Target (described in Appendix I hereto) for the five year period ended on the last day of the fiscal quarter immediately preceding the fifth anniversary of the Loan Date. The Board shall notify Thorburn of its determination no later than five days before the fifth anniversary of the Loan Date. For the avoidance of doubt, it is in the sole and absolute discretion of the Board to forgive any part of the Principal Amount or Interest if either or both of the foregoing targets are achieved. (c) Prior to the fifth anniversary of the Loan Date, in the event Thorburn's employment is terminated due to Thorburn's death or Disability (as such term is defined in Thorburn's Employment Agreement with SCI, LLC), the Board, in its sole and absolute 1 2 discretion, may consider at the time of the termination event by death or Disability forgiving all or any portion of the Principal Amount and/or accrued Interest. 2.
