|Eligibility |  | Company officers and employees in job grades 26 and above are eligible to participate in the Plan. At the discretion of the President, other employees in job grades 22 and above and exempt
profit center employees in job grades 18 and above may be eligible to participate in the Plan.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
|            | 
|            |  | If an employee becomes a participant in the Plan during a calendar year, he or she may be eligible, at the discretion of the President, for a pro rata share of a bonus based on the portion of
the calendar year he or she was a participant. If an employee who is a participant in the Plan moves from one job grade level to another during a calendar year, he or she may be eligible, at the discretion of the President, for a bonus pro rated on
the basis of time spent at each job grade level during the calendar year.                                                                                                                                                                                                                                                                                    
|            | 
|            |  | An eligible employee who dies or retires, or whose employment is otherwise terminated during the calendar year, or who becomes ineligible to participate in the Plan during the calendar year, or
gives notice of his or her intent to terminate his or her employment subsequent to the end of the calendar year but prior to the date on which the Incentive Bonus Awards are issued, may receive all, none, or any part of the amount such employee
would have received if his or her eligibility had been for the full calendar year. In determining what bonus, if any, such employee is to receive, the President may consider, among other matters, the employees performance during the calendar
year and the number of months during the calendar year the employee was eligible to participate in the Plan.
|            | 
|            |  | If an employees employment with the Company is terminated for any reason, including death, disability, termination by the Company or resignation by the employee, prior to any of the
vesting dates of the Restricted Stock award, then all unvested shares of Restricted Stock shall be immediately forfeited as of the date of termination. At the discretion of the President, restrictions or forfeitures relating to Restricted Stock of
an employee may be waived in whole or in part and such waiver may vary among individual employees.

|Performance Measurement |  | The central measurement element of the Plan will be Return on Equity (ROE). Each year, the Board will approve a Company Target ROE and a Target combined ratio for each
designated Business Unit. Profit Centers will be judged on Target combined ratio. Support Units will be judged on specific results that are key to performance and the Company Target ROE. Service Income Units will be judged on Target net
income.
|                        | 
|                        |  | In addition to Target performance levels, the Board will approve Unacceptable, Threshold and Stretch performance levels. Performance levels for the Plan year will be communicated to
all eligible participants subsequent to approval by the Board.

applicable, and a stock premium as applicable all as described in the Definitions section of this Plan document.

|                        |  | If Unacceptable performance levels (results below the Threshold level) are achieved, no bonus will be paid under the Plan.

|                        |  | If performance results are less than or greater than Target (but above the Threshold level and below the Stretch level), the standard bonus opportunity (and, consequently, the final
awards) will be proportionately higher or lower.
