Are There Any Restrictions on Contract Benefits?

Yes. •There are restrictions and limitations relating to the benefits offered under the Contract (e.g., death benefits). •Except as otherwise provided, Contract benefits may not be modified or terminated by us. •Partial surrenders (including any applicable surrender charges and fees) and partial annuitizations will reduce the value of the death benefit, perhaps significantly, and reduction could be greater than the amount withdrawn. •The following were optional benefits that may have been available for purchase at the time you purchased your Contract: the Premium Payment Credit Rider; the Principal Income Builder 3 (“PIB 3”) or Principal Income Builder 10 (“PIB 10”), both of which are GMWB riders; Enhanced Death Benefit rider; GMWB 1 rider, GMWB 2-SL Rider or GMWB 2-SL/JL Rider (all three of which were earlier types of GMWB riders) . Having the Premium Payment Credit Rider extends the surrender charge period for your Contract and the value of the credit may be more than offset by the additional charges for the rider. Having a GMWB rider: limits your underlying investment options; restricts your ability to terminate the rider until the 5th Contract anniversary; and, if you take excess withdrawals, you will shorten the life of the rider, lower the withdrawal benefit payment(s) and/or cause the rider to terminate for lack of value. •Depending on your state, or your financial professional or your financial professional's firm, certain benefits may not be available or may be available on different terms.

GMWB Self-Build Models

GMWB Self-Build Models are not available for Contracts issued on or after January 4, 2010.

Each of the GMWB Self-Build Models requires You to allocate Your Separate Account Division Value and Premium Payments in specified percentages among asset classes and provides You limited ability to select the Separate Account Divisions that You wish to use to meet those allocation requirements. The major asset classes on which each model is based and the required allocations among those asset classes are shown in the following table.

Asset Class			Model A			Model B			Model C			Model D
Short-Term Fixed Income			30%			20%			10%			15%
Fixed Income			40%			30%			20%			15%
Balanced/Asset Allocation			10%			15%			20%			25%
Large US Equity			20%			25%			30%			25%
Small/Mid US Equity			0%			5%			15%			0%
International Equity			0%			5%			5%			20%

If You are invested in a GMWB Self-Build Model, You are directing us to allocate Your Separate Account Division Value and Premium Payments according to the allocation percentages You have set. In addition, You are directing us to automatically rebalance Your Separate Account Division Value each calendar quarter to match the allocation percentages You set in Your GMWB Self-Build Model. The sum of the percentages that You allocate to the Separate Account Divisions in an asset class or sub-class must equal the required aggregate percentage for that asset class or sub-class. The sum of the percentages You invest in all the asset classes must equal 100% of Your Separate Account Division Value.

You may Transfer among the divisions within an asset class or sub-class as long as Your allocations for that asset class or sub-class equal the percentage established by Your chosen GMWB Self-Build Model, and You adhere to the Transfer provisions of Your Contract. We currently do not charge a fee for a Transfer. If we start charging a fee in the future, we will not impose such fee on the quarterly Automatic Portfolio Rebalancing.

You should note that most of the underlying funds available as options under the GMWB Self-Build Models are series of Principal Variable Contract Funds, Inc., which invest Your Contract value predominantly in underlying funds that are not managed by an affiliate of ours, a GMWB rider may not be appropriate for You.

To the extent that an underlying fund managed by PMC may be included as an option under a GMWB Self-Build Model, PMC will receive additional compensation from the management fee of the underlying fund. However, we do not take such potential financial benefit into account in selecting the underlying fund to be an option under a GMWB Self-Build Model.

We reserve the right to modify the list of available Separate Account Divisions in a GMWB Self-Build Model, subject to compliance with applicable regulations. We may make available other GMWB Models. We may also make changes to or restrict the availability of GMWB Models. Changes or restrictions will apply only to new purchases of the Contract or to You if You Transfer out of a GMWB Model and wish to Transfer back to that model.

In maintaining a GMWB Self-Build Model, You should consider Your personal objectives, investment time horizons, risk tolerance and other financial circumstances. You should also remember that asset allocation does not insure a profit or protect against loss. You may wish to ask Your financial representative for assistance in maintaining a model and choosing among the Separate Account Divisions available under that model. To discuss whether Your selections remain appropriate for Your needs, contact Your financial professional.
