1 EXHIBIT (5)(b) SUPPLEMENTAL TERM INSURANCE RIDER - -------------------------------------------------------------------------------- We, National Life Insurance Company, will pay the Supplemental Term Insurance Amount, subject to the terms of this rider, in addition to the Death Benefit of this policy, when we receive at our Home Office due proof that the Insured died while this rider was in force. The date of issue of this rider is the policy Date of Issue unless a later date is set forth below. SUPPLEMENTAL TERM INSURANCE AMOUNT Under Option A, the Supplemental Term Insurance Amount shall be the Term Insurance Amount stated in the Policy Schedule A less any excess of the policy Death Benefit Standard over: 1. the policy Face Amount on the date of the Insured's death; less 2. the amount of any Monthly Deductions then due; less 3. any debt to us on this policy; but not less than zero. Under Option B, the Supplemental Term Insurance Amount shall be the Term Insurance Amount stated in the Policy Schedule A less any excess of the policy Death Benefit Standard over: 1. the policy Face Amount on the date of the Insured's death; plus 2. the Account Value of the policy on the date of the Insured's death; less 3. the amount of any Monthly Deductions then due; less 4. any debt to us on this policy; but not less than zero. Option B will not be available if the Death Benefit Compliance Test is The Cash Value Accumulation Test. We will pay the Supplemental Term Insurance Amount to the Beneficiary when we receive at our Home Office due proof that the Insured died while this rider was in force. We will pay the Supplemental Term Insurance Amount in one sum unless a Payment Option, as described in the policy to which this rider is attached, is chosen. If the Supplemental Term Insurance Amount is paid in one sum, it shall be increased by interest from the date of the Insured's death to the date of payment. We will set the rate of interest at not less than the Basis of Computations Interest Rate shown in the Policy Schedule.

Payment will be made to the Beneficiary. COST OF SUPPLEMENTAL TERM INSURANCE AMOUNT The Cost of Supplemental Term Insurance Amount rate on any day shall be based on the Insured's then Attained Age, sex (if applicable) and the rate class of the Term Insurance Amount on the date of issue of this rider. On any Monthly Policy Date, the Cost of Supplemental Term Insurance Amount shall be the product of: 1. the Cost of Supplemental Term Insurance Amount rate on such date divided by $1,000; multiplied by 2. the Supplemental Term Insurance Amount on such date, divided by the sum 1.00 plus the monthly Basis of Computations Interest Rate shown in Policy Schedule A. We may change the Cost of Supplemental Term Insurance Amount rates from time to time based on our expectations of future experience. Any change in the Cost of Supplemental Term Insurance Amount rates shall apply to all riders of the same size and duration, insuring persons of the same Attained Age and rate class as the Insured. The Cost of Supplemental Term Insurance Amount rates shall not be greater than the rates set forth in the table of Guaranteed Maximum Cost of Insurance Rates shown in Policy Schedule E. These rates are based on the Mortality Table named in Policy Schedule A. SUPPLEMENTAL TERM INSURANCE AMOUNT DECREASES The Owner may request that the Supplemental Term Insurance Amount be decreased. A decrease may only be made during the lifetime of the Insured. We will send the Owner a revised Policy Schedule if a decrease is made. We will require a written request from the Owner. A decrease in the Supplemental Term Insurance Amount shall be effective on the Monthly Policy Date on or next following our receipt of the request. Decreases will not be permitted which would reduce the sum of the Face Amount plus the amounts insured in force under this policy to less than any of the following: 1. the minimum coverage amount for which the policy would qualify as "Life Insurance" for Federal Income Tax purposes under the Internal Revenue Code; or 2. the Minimum Face Amount shown in the Policy Schedule.

If both an increase in Face Amount and the addition of a Supplemental Term Insurance Rider providing coverage on the life of the Insured became effective on the same date, a decrease in total coverage made effective on that date shall apply in the following order: 1. first, to any increase in total insurance coverage resulting from the addition of an Supplemental Term Insurance Rider providing coverage on the life of the Insured; 2. second, to any increase in Face Amount; 3. third, to the Face Amount on the Date of Issue.
