National Western Life Insurance Company2017EXECUTIVE OFFICER BONUS PROGRAM - ADDENDUM

The Program incorporates three measurable performance factors: (1) Company sales, which are defined as net placed annualized target premium for Life business and as total placed premium for Annuity business, (2) Company expense management, and (3) overall profitability.

The maximum bonus percentage under the Program is 150% for the CEO and 75% for the President. The targeted weighting of the total bonus percentage (applied to Base Salary (as defined below)) for the three measurable performance factors is 30% for sales performance, 30% for expense management performance, and 40% for profitability. Actual results will be compared to the performance target grids and can either increase or decrease each of the individual performance factor bonus percentages as explained in the following sections. For purposes of the Program, the Base Salary of each Executive Officer is the officer’s annual base salary for 2017 as certified by the Committee.

The sales component of the Program is further subdivided between Life production and Annuity production. For 2017, the bonus sales goals for each line of business of the Company are:

International Life -- $15,500,000 net placed annualized target premium

Domestic Life -- $20,000,000 net placed annualized target premium

The Company’s New Business Market Summary Report (NWAR60) and the equivalent LifeCycle 2.0 sales report will be the source of sales results for purposes of this Program. The bonus percentage corresponding with each sales production level achieved in 2017 will be applied to 100% of the Participant’s Base Salary in accordance with the following grid:

If net placed annualized target premium or total placed premium, as applicable, for a segment is below the lowest target amount for that segment, no bonus percentage will be earned for that segment. The bonus percentage shown for each specified amount of net placed annualized target premium or total placed premium, as applicable, applies if actual performance is equal to or greater than the amount shown and, except for the last level, is less than the amount shown for the next level.

The expense component of the Program is based upon a ratio of actual expenses as reported in the Company’s statutory financial statements to a targeted level of expenses based upon historical ratios of life expenses to life premiums and annuity expenses to annuity premiums. For purposes of this measurement, expenses include General Expenses; Taxes, Licenses & Fees; and the Change in Loading as reported in the Company’s statutory income statement.

Targeted expense levels will be determined by applying historical expense-to-premium factors, separately for life and annuity lines of business, to actual premiums during the bonus period. These historical factors are as follows:

Actual expenses will be compared to targeted expenses for purposes of determining a ratio. The “par” ratio of actual expenses to targeted expenses is 100% for this bonus component. The bonus percentage corresponding with the actual expense to targeted expense ratio achieved will be applied to 100% of each Participant’s Base Salary in accordance with the following grid:

The bonus percentage shown for each specified range level applies if the ratio of actual expenses to targeted expenses achieved is greater than the lower limit shown in the level and, except for the last level, is equal to or less than the upper limit shown for the same level. For purposes of the expense component, special consideration may be given at the discretion of the Compensation Committee for items of an unusual and/or non-recurring nature (e.g., lawsuit settlements, excess pension contributions) that are beyond the control of Company management.

The profitability component of the Program is based upon the consolidated GAAP return on assets (ROA) percentage as derived from the segment results reported in National Western Life Group Inc.’s (NWLGI) Form 10-K. The ROA percentage is calculated as the sum of GAAP segment net operating earnings divided by the sum of the beginning of the year GAAP segment assets. Segment GAAP net operating earnings are after federal income taxes but exclude realized gains and losses on investments. As the GAAP results, including segment information, reported in the Form 10-K are audited by the Company’s independent auditors, the ROA calculation will be finalized at the time NWLGI’s Form 10-K for the year is filed with the SEC.

The bonus percentage corresponding with the actual ROA percentage for 2017 will be applied to 100% of each Participant’s Base Salary in accordance with the following grid:

If the actual ROA percentage achieved in 2017 is less than the lowest percentage shown (0.65%), no bonus percentage will be earned. The bonus percentage shown for each specified ROA percentage range level applies if the actual ROA percentage achieved is greater than the lower limit shown in the level and, except for the last level, is equal to or less than the upper limit shown for the same level.

Determination of Bonuses.  After audited GAAP financial statements become available for the 2017 performance period, the Committee shall determine the extent to which the three measurable performance factors have been achieved and the bonus percentage for the Participants for 2017. The Committee shall certify such determination in writing. The Company’s independent auditors will also review the calculation of the bonus percentage for compliance with the details of this Program as part of the Company’s audited financial statements. Notwithstanding any contrary provision of the Program, the Committee, in its sole discretion, may eliminate or reduce the bonus payable to any Participant below that which otherwise would be payable under the Program formula.

Timing and Form of Payment.  After the bonus amount is certified by the Committee, the bonuses shall be paid in cash in a single lump sum. Such payment shall occur on or after January 1, 2018 and on or before March 15, 2018. Bonus payments are intended to qualify as short-term deferrals under section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and shall be paid not later than the latest specified payment date (March 15, 2018). The Company shall have the authority to delay the payment of any bonus under the Program to the extent it deems necessary or appropriate to comply with Code section 409A(a)(2)(B)(i).

Effect of Termination.

If a Participant terminates employment with the Company for any reason after the end of the 2017 performance period but prior to the date the bonus for such period is paid, the Participant shall be entitled to payment of the bonus determined by the Committee, subject to reduction or elimination under the last sentence of the “Determination of Bonuses” paragraph above based on the circumstances surrounding such termination of employment.

If a Participant terminates employment with the Company prior to the end of the applicable 2017 Performance Period for any reason other than termination for cause by the Company (as determined by the Committee in its sole discretion), the Committee shall reduce the Participant’s bonus proportionately based on the date of termination (and subject to further reduction or elimination under the last sentence of the “Determination of Bonuses” paragraph above based on the circumstances surrounding such termination of employment).

If a Participant is terminated for cause by the Company prior to the payment of any bonus, no bonus shall be payable hereunder.

If a Participant dies prior to the payment of a bonus payable hereunder, the bonus shall be paid to the Participant’s beneficiary of record.

Source of Payments.  Bonuses that may become payable under the Program shall be paid solely from the general assets of the Company. The rights of each Participant (and any person claiming entitlement by or through a Participant) hereunder shall be solely those of an unsecured general creditor of the Company. The Program shall be unfunded. The Company may maintain bookkeeping accounts with respect to Participants who are entitled to bonuses under the Program, but such accounts shall be used merely for bookkeeping convenience. The Company shall not be required to segregate any assets that may at any time be represented by interests in bonuses nor shall the Program be construed as providing for any such segregation.

Committee Administration.  The Program shall be administered by the Committee. The Committee shall have complete discretion and authority to administer the Program and to interpret the provisions of the Program. Any determination, decision, or action of the Committee in connection with the construction, interpretation, administration, or application of the Program shall be final, conclusive, and binding upon all persons, and shall be given the maximum deference permitted by law. The Committee may amend or terminate the Program at any time without the consent of any Participant by adoption of a written instrument.

Miscellaneous.  

The Company shall withhold all applicable taxes and other amounts required by law to be withheld from any bonus payment, including any non-U.S., federal, state, and local taxes.

A Participant’s rights under this Program will not be assignable, transferable, pledged, or in any manner alienated, whether by operation of law or otherwise, except as a result of death or incapacity where such rights are passed pursuant to a will or by operation of law. Any assignment, transfer, pledge, or other disposition in violation of this provision will be null and void.

Nothing in the Program shall interfere with or limit in any way the right of the Company to terminate any Participant’s employment at any time, nor confer upon any Participant any right to continue in the employment of the Company.

Bonuses payable hereunder shall constitute special discretionary incentive payments to the Participants and will not be required to be taken into account in computing the amount of salary or compensation of the Participants for the purpose of determining any contributions to or any benefits under any pension, retirement, profit-sharing, bonus, life insurance, severance or other benefit plan of the Company or under any agreement with a Participant, unless the Company specifically provides otherwise.

The Program and all determinations made and actions taken pursuant hereto, to the extent not otherwise governed by the Code, shall be governed by the laws of the State of Texas, without giving effect to conflict or choice of laws provisions thereof.

This Program shall be binding upon and inure to the benefit of the Company, its successors and assigns, and the Participants, and their heirs, assigns, and personal representatives.
