1 EXHIBIT 1.A.(5)(b) GUARANTEED DEATH BENEFIT RIDER We, National Life Insurance Company, guarantee that the policy will not lapse if and as long as the Conditions of this Rider are met. This no-lapse guarantee ensures that a Death Benefit will be payable under this policy for as long as this rider remains in force. The date of issue of this rider is the policy Date of Issue. MONTHLY GUARANTEE PREMIUM. The Monthly Guarantee Premium specific to this rider is stated in the Data Section. It is subject to change upon increases or decreases in Face Amount, and upon changes in the Death Benefit Option of this policy. CONDITIONS OF THIS RIDER. To keep this rider in force, cumulative premiums paid in excess of withdrawals and debt, accumulated to each Monthly Policy Date at an annualized interest rate of 4% per year, must on each Monthly Policy Date equal at least the sum of all unique Monthly Guarantee Premiums in effect since the Date of Issue of the policy times the number of Monthly Policy Dates that elapsed while each Minimum Monthly Premium was in effect, minus the Monthly Guarantee Premium due on that given Monthly Policy Date. Compliance with this condition will be determined on every Monthly Policy Date. IMPACT OF WITHDRAWALS AND POLICY LOANS. Withdrawals and Policy Loans taken against this policy will impact the calculation described in Conditions of this Rider. If a Withdrawal made or Policy Loan taken against this policy leaves the policy out of compliance with the Conditions of this Rider, a Notice of Pending Termination of this Rider will be sent to the Owner. COST OF THIS RIDER. The monthly cost of this rider is shown in the Data Section. It shall be based on the Face Amount of the policy. If, while this rider is in force, any increase or decrease in the Face Amount of the policy is made, the monthly cost of this rider will similarly increase or decrease. The monthly cost of this rider shall be deducted from the Accumulated Value of the policy in the same manner as is the Monthly Deduction. SUSPENSION OF MONTHLY DEDUCTIONS. If, while this rider is in force, the Accumulated Value of the Policy is not sufficient to cover the Monthly Deductions and the monthly costs of any riders on the policy, Monthly Deductions and the monthly costs of any riders on the policy will be deducted from the Accumulated Value until the Accumulated Value is exhausted, and will thereafter be deferred until such time as the policy has positive Accumulated Value. Upon the death of the Insured, we will waive that portion of any Monthly Deductions and monthly costs of any rider on the policy then in arrears. INCONTESTABILITY. After this rider has been in force during the life of the Insured for two years from its date of issue, we will not contest it. CONSIDERATION.
