|:---|:---|
| **FEES, EXPENSES AND ADJUSTMENTS** | **FEES, EXPENSES AND ADJUSTMENTS** |
| **Are There Charges or Adjustments for Early Withdrawals?** | **Yes.** If the Investor withdraws money from the Contract within ten (10) Contract Years, the Investor can be assessed an early withdrawal charge equal to a maximum of 5% of the amount withdrawn.<br>For example, if you make an early withdrawal from the Corporate 401 Contract, you could pay a surrender charge of up to $5,000 on a $100,000 investment.

For example, you allocate $100,000 to the GAA with a 3-year Guaranteed Term and later withdraw the entire amount before the 3 years have ended, you could lose up to $100,000 of your investment. This loss will be greater if you also have to pay a surrender charge, taxes, and tax penalties. A ("MVA") may apply if you withdraw or transfer Account Value from the GAA, or upon payments due to the death of the participant, if paid more than six months following death (or disability, if applicable).<br> **See "FEE TABLE** **- *Transaction Expenses," "FEE TABLE - Adjustments,"* "CHARGES, FEES AND ADJUSTMENTS - *Transaction Fees -* Early Withdrawal Charge," and "CHARGES, FEES AND ADJUSTMENTS - *Market Value Adjustments"* in the full Contract prospectus.** |

<sup>1</sup> As a percentage of average Account Value.

<sup>2</sup> The Base Contract Expenses include (1) the mortality and expense risk charge (1.25% for HR 10 Contract, SEP Contract and Group IRA Contract and 1.19% for Corporate 401 Contract), which compensates us for the mortality and expense risks we assume under the Contract, including those risks associated with our funding of the death benefit; (2) an administrative expense charge of up to 0.25%; and (3) a $30 annual maintenance fee converted to an annual percentage equal to 0.000755455%.

The annual maintenance fee is not applied to amounts held under Group IRA certificates and may be reduced or waived in certain circumstances for the other Contract. The minimum amount reflects these reductions or waivers, while the maximum amount does not. Additionally, the minimum amount reflects the lower mortality and expense risk charge for Corporate 401 Contract and the maximum amount reflects the higher mortality and expense risk charge for the other Contracts. **See "CHARGES, FEES AND ADJUSTMENTS** **- *Periodic Fees and Charges*" in the full Contract prospectus.**

The Contract is typically most useful as part of a personal retirement plan.

At the end of the Guaranteed Term we will reallocate your Account Value in the GAA according to your instructions. If you have not provided instructions, we will automatically reinvest the maturing investment into a guaranteed term available in the current deposit period. For contracts that distinguish between short- and long-term classifications, we will generally transfer the maturing investment to the available deposit period for the guaranteed term having the shortest maturity within the same classification. For other contracts, we will generally transfer the maturing investment in the following manner based upon availability:<br> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To a guaranteed term of the same duration, if available;<br> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To a guaranteed term with the next shortest duration, if available; or<br> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To a guaranteed term with the next longest duration.<br>**See "PRINCIPAL RISKS OF INVESTING IN THE CONTRACT" in the full Contract prospectus.** |
