The principal amount shall be non-interest bearing, except in the event of default as provided herein. 2. The first minimum principal payment of $500,000 shall be due and payable four years from the date of this note, with three additional minimum installments of $500,000 each due and payable each anniversary date thereafter.

Notwithstanding the foregoing, any allocation of expenses from SouthCentral to the Royal Door business unit in excess of $5,000 per month must be agreed to by James E. Rowland or his assign for purposes of calculating earnings of the business unit. The accelerated principal payment shall be paid no later than thirty (30) days following the anniversary date of this note.

The principal balance of the note shall be reduced by $2 million if voluntary termination of employment occurs within one year of the date of this note, and the principal balance shall be reduced by $1 million if termination of employment during the second year of employment by SouthCentral. If John Rowland voluntarily leaves the employment of SouthCentral during the first year of operation after the acquisition, SouthCentral will not receive the benefit of its bargain. As liquidated damages, and not as a penalty, the parties agree that the principal amount of the note may be reduced by the following amounts upon John Rowland voluntarily leaving the employment of SouthCentral, provided that the job descriptions, place of employment, hours, duties or salary are not adversely changed from the date of the Compensation Agreement. The principal balance of the note shall be reduced by $1 million if voluntary termination of employment occurs within one year of the date of this note. Voluntary termination of employment of either James Rowland or John Rowland shall not include death or disability of the employee. 6. SouthCentral may prepay the remaining outstanding principal at any time without any additional cost. 7. SouthCentral and Royal Door are parties to an Asset Purchase Agreement dated _______________, as amended (the "Agreement").

If Royal Door objects to the set-off in writing prior to the expiration of the 30-day notice period, the parties shall attempt to negotiate a resolution of Royal Door's objection and SouthCentral's claim of set-off. If the parties cannot reach agreement within 30 days, SouthCentral shall commence an interpleader action to resolve the dispute and pay the amount of set-off into the court in which the interpleader action is pending. 8. Royal Door may not assign the right to receive proceeds of this note without the consent of SouthCentral. 9. If SouthCentral defaults in payment of principal under the terms of this note or is in default in any other manner under the terms of this note, the outstanding principal amount shall, upon 10 days notice of default by Royal Door and SouthCentral's failure to pay, shall become immediately due and payable in full.
