PRINCIPAL® OUTCOME PROTECTOR

INDEX-LINKED DEFERRED ANNUITY

Prospectus dated __________, 202___

This prospectus describes the Principal® Outcome Protector, an individual, single premium, index-linked deferred annuity (the “Contract”), issued by Principal Life Insurance Company (“the Company,” “we,” “our” or “us”). The Contract is designed to help individuals accumulate part of their retirement savings and achieve other long-term investment goals, as well as provide retirement income through Annuitization. The Contract is a single premium product, which means that no additional Premium Payments can be made after the Contract Date.

This prospectus provides information about the Contract that you, as Owner (“you” or “your”), should know before investing. It describes all material rights and obligations under the Contract and any material differences due to state variations. The Contract or certain of its Segment Options and/or features may not be available in all states or with all broker-dealers. Please review this entire prospectus and talk with your financial professional to obtain specific information.

These securities have not been approved or disapproved by the Securities and Exchange Commission (“SEC”) or any statesecurities commission, nor has the SEC or any state securities commission passed uponthe accuracy or adequacy of this prospectus. Any representation to the contrary is acriminal offense.

If you are a new investor in the Contract, you may cancel your Contract within 15 calendar days of receiving it. In some states, this cancellation period may be longer. Upon cancellation you will receive either a full refund of your Premium Payment or your total Contract Accumulated Value. The Contract Accumulated Value would be subject to the Bond Adjustment and Segment Interim Value calculation if your Premium Payment is allocated to a Segment Option. If you receive the Contract Accumulated Value, you assume the risk of any market drop on Premium Payment allocated to the Index-Linked Segment Options. You should review this prospectus and consult with your financial professional for additional information about the specific cancellation terms that apply.

The minimum Total Premium Payment is $20,000. After a limited period of time during which your Total Premium Payment (and any credited interest) is held in the Initial Holding Account, you may allocate your Premium Payment and earnings, if any, among the Contract’s investment options. These include index-linked investment options (“Index-Linked Segment Options”) and a fixed interest investment option (“Fixed Segment Option”). Each investment option has an investment term of either one, two, or six years (“Segment Term”).

Each Index-Linked Segment Option is tied to the performance of a specific market index (“Index”) for a Segment Term. Each has either a floor or buffer feature providing limited protection against negative Index performance at the end of the Segment Term. Each also has a cap and participation rate feature that potentially limits gain from positive Index performance at the end of the Segment Term. The Fixed Segment Option credits interest at a fixed rate during the Segment Term.

Any guarantees under this Contract are subject to the rights of the Company’s other creditors and the Company's overall claims-paying ability.

Index-linked deferred annuity contracts are complex insurance and investment vehicles. This Contract is a security and there is a risk of substantial loss of your principal and earnings. The risk of loss may be greater when early withdrawals (full or partial) are taken due to any charges and adjustments applied to such withdrawals. These charges and adjustments may result in loss even when the value of a Segment Option has increased. Refer to the RISK FACTORS section beginning on page [to be added by amendment] of this prospectus for important information about the Contract’s investment risks. You should talk with a financial professional about the Contract’s features, benefits, risks and fees, and whether the Contract is appropriate for you based on your financial situation and objectives.

An investment in the Contract is not a deposit or obligation of any bank and is notinsured or guaranteed by any bank, the Federal Deposit Insurance Corporation or anyother government agency.

The principal underwriter of the Contract is [to be added by amendment].

No person is authorized to give any information or to make any representation in connection with this Contract other than those contained in this prospectus.

1.GLOSSARY

The terms defined below are used throughout this prospectus. These terms are capitalized throughout this prospectus with the exception of “we,” “our,” “us,” “you” and “your.”

Accumulated Value (Contract Accumulated Value) - the sum of the Segment Interim Values, Segment Values, and Fixed Segment Values, as applicable, plus the total value of any allocation to the Initial Holding Account.

Annuitant - the person, including any Joint Annuitant, whose life determines the annuity benefit under this Contract.

Annuitization (Annuitize) - the application of a portion or all of the Accumulated Value, adjusted for the Bond Adjustment, to an annuity benefit payment option to make annuity benefit payments.

Annuitization Date - the date all of the Owner’s Accumulated Value is applied to an annuity benefit payment option.

Bond Adjustment - an adjustment (which could be positive, negative, or equal to zero) to the amount Surrendered based on the change in the fair value of the hypothetical fixed income assets supporting our financial obligations under the Contract.

Buffer Rate - for each Buffer Segment Option, the maximum amount of negative Index performance we will absorb at the end of the Segment Term. You will be responsible for any negative Index performance that exceeds the Buffer Rate, which could result in significant loss of principal, credited interest and/or prior earnings.

Buffer Segment Option - any Index-Linked Segment Option that includes a Buffer Rate. If you select a Buffer Segment Option for investment, your investment will incur loss at the end of the Segment Term for any negative Index performance beyond the Buffer Rate. If negative Index performance does not go beyond the Buffer Rate, you will not incur loss as a result of negative Index performance. For example, if a particular Segment Option has a 10% Buffer Rate and the Index Change at the end of the Segment Term is -15%, your investment tied to that Segment Option will lose 5%. If the Index Change at the end of that Segment Term had been -8%, your investment would have lost 0%.

Cap Rate - if you select an Index-Linked Segment Option with a Cap Rate for investment, at the end of the Segment Term, you may participate in any positive Index performance up to the Cap Rate, but no positive Index performance beyond the Cap Rate. For example, if the Segment Option has a 20% Cap Rate and the Index Change at the end of the Segment Term is 12%, your investment tied to that Segment Option will gain 12%. If the Index Change at the end of that Segment Term had been 25%, your investment would only have gained 20% due to the Cap Rate limitation.

Contract Anniversary - the same day and month as the Contract Date in each Contract Year.

Contract Date - the date the Contract is issued and that is used to determine Contract Years.

Contract Year - the one-year period beginning on the Contract Date and ending one day before the Contract Anniversary and each subsequent one-year period beginning on a Contract Anniversary. For example, if the Contract Date is June 5, 2023, the first Contract Year ends on June 4, 2024, and the first Contract Anniversary falls on June 5, 2024.

Crediting Base - for each Index-Linked Segment Option selected for investment, the amount allocated to the Segment Option on the Segment Start Date, reduced by a negative adjustment upon any Surrender or deduction of charges or fees from that Segment Option prior to the Segment End Date. Negative adjustments to the Crediting Base are generally proportional and always negative. A negative adjustment could be greater than the amount Surrendered or deducted.

Data Page(s) - the portion of the Contract that contains information specific to your Contract.Current or revised Data Pages may be sent to you from time to time that reflect the current status of your Contract.

Equity Adjustment - for each Index-Linked Segment Option selected for investment, an adjustment (which could be positive, negative, or equal to zero) used to calculate the Segment Interim Value on each Valuation Day between the Segment Start Date and Segment End Date. The Equity Adjustment, which is expressed as a percentage, is based on the change in the fair value of the hypothetical derivative assets that we use to support our financial obligations under the Contract.

Fixed Segment Option - any investment option that credits interest at a fixed rate for a Segment Term.

3

Fixed Segment Value - for each Fixed Segment Option selected for investment, the Accumulated Value allocated to the Segment Option on the Segment Start Date, plus interest credited to that Segment Option during the Segment Term, less any amount deducted from that Segment Option during the Segment Term.

Floor Rate - for each Floor Segment Option, the maximum amount of negative Index performance you could absorb at the end of the Segment Term. We will absorb any negative Index performance that exceeds the Floor Rate.

Floor Segment Option -any Index-Linked Segment Option that includes a Floor Rate. If you select a Floor Segment Option for investment, your investment will incur loss at the end of the Segment Term for any negative Index performance up to the Floor Rate, but your investment will not incur loss for any negative Index performance beyond the Floor Rate. For example, if the Segment Option has a 10% Floor Rate and the Index Change at the end of the Segment Term is -5%, your investment will lose 5%. If the Index Change at the end of the Segment Term had been -15%, your investment would have only lost 10% because of the 10% Floor Rate.

Free Surrender Amount - the amount that may be Surrendered through a full or partial withdrawal from the Contract without a Surrender Charge. Equity and Bond Adjustments will still apply to the Free Surrender Amount.

Good Order - when an instruction or request is received in our Home Office, or other place we may specify, and it has such clarity and completeness that we do not have to exercise any discretion to carry out the instruction or request. We may require that the instruction or request be given in a certain form.

Guaranteed Minimum Interest Rate - the guaranteed minimum annual interest rate for the Initial Holding Account and any Fixed Segment Option.

Home Office - Company’s corporate headquarters located at Principal Financial Group, Des Moines, Iowa 50392-1770.

Joint Owner(s) - an Owner who has an undivided interest with the right of survivorship in this Contract with another Owner. Any reference to the death of the Owner means the death of the first Owner to die.

Lock-In Date – the Valuation Day we receive Notice in Good Order to lock in the Segment Option or, if there are Lock-In Threshold(s) established for the Segment Option, the Valuation Day where the Equity Adjustment reaches and/or crosses the threshold you set.

Lock-In Threshold – an upper and/or lower level (threshold) for a Segment Option and, if the performance of the Index during a Segment Term reaches and/or crosses that level, the Segment Lock-In is automatically triggered for that Segment Option. An upper threshold is a threshold that is above the current Equity Adjustment and a lower threshold is a threshold that is below the current Equity Adjustment.

That percentage will equal the Participation Rate. For example, if the Segment Option has a 90% Participation Rate and the Index Change at the end of the Segment Term is 10%, your investment will gain 9%.

Segment Credit – the amount of gain or loss applied to your investment on the Segment End Date for each Index-Linked Segment Option selected for investment. The Segment Credit is calculated only on the Segment End Date. The Segment Credit is calculated by (i) multiplying the Crediting Base by the Index Change, and then (ii) applying the Index-Linked Segment Option’s Buffer Rate, Floor Rate, Cap Rate, and/or Participation Rate, as applicable. Segment Credits could be positive, negative, or equal to zero. If Segment Credits are negative, you will lose principal and/or prior earnings.

2.     RISK FACTORS

Risk of Loss

An investment in this Contract is subject to the risk of poor investment performance of the Index-Linked Segment Options to which you have allocated Accumulated Value. You can lose money by investing in this Contract, including loss of principal, previously credited interest and/or prior earnings. While limited protection from losses is provided under your Contract through either a Buffer Segment Option or Floor Segment Option, you bear some level of the risk of decline in your Contract’s Accumulated Value resulting from the performance of the Index-Linked Segment Options and the risk of losses may be significant. For additional information, see 7. INDEX-LINKED SEGMENT OPTION MECHANICS.

Risk of Loss in Exercising Free Look

In the states that require us to return your Premium Payment upon your exercising your free look rights, we will return the greater of your Premium Payment or Accumulated Value. In other states we will return at least your Accumulated Value plus any premium tax charge deducted, and minus any applicable federal and state income tax withholding. For these states, the risk to you is that you may receive less money upon the exercise of your free look rights than you paid into the Contract in Premium Payment. This risk exists because your Contract Accumulated Value can decrease during the free look period. For additional information, see 5. PURCHASING THE CONTRACT - Right to Examine the Contract (Free Look).

Index Performance Risk

The Accumulated Value of your Contract is dependent on the performance of the Index-Linked Segment Options to which you have allocated any of the Accumulated Value. Based on your investment objectives, you direct the allocation of the Accumulated Value, which takes effect at the applicable Segment Start Date. There can be no assurance that your investment objectives will be achieved.

The performance of an Index is based on changes in the values of the securities or other investments that comprise or define the Index. The securities comprising or defining the Indices are subject to a variety of investment risks, many of which are complicated and interrelated.

Because the Index-Linked Segment Options are each comprised of a collection of equity securities, the value of the component securities is subject to market risk and issuer risk. Market risk is the risk that the respective market ups and downs likely will cause the value of the securities to go up or down. The ups and downs can be because of disasters and other events, such as storms, earthquakes, fires, outbreaks of infectious diseases, terrorist attacks, political and social developments, and military and governmental actions. Equity markets also are subject to the risk that the value of the securities may fall due to general market and economic conditions.

The value of equity securities also may go up or down for reasons directly related to the issuers of the securities. This issuer risk is the risk that the value of an issuer’s securities may decline for reasons directly related to the issuer, as opposed to the market generally.

The performance fluctuations of the Indices can occur rapidly and unpredictably, and negative Index performance can cause you to have investment losses. While you will not be directly invested in the Index, if you allocate amounts to an Indexed-Linked Segment Option, you will have indirect exposure to the investment risks of the applicable Index. For additional information, see 7. INDEX-LINKED SEGMENT OPTION MECHANICS.

Investing in the Contract does not mean you are invested in the companies that comprise the Indexes. You will have no voting rights, no rights to receive cash dividends or other distributions, and no other rights with respect to the companies that make up the Indexes.

Each of the Indices available under this Contract has its own unique risks. They are discussed here.

The S&P 500® Price Return Index

This index is comprised of equity securities issued by large-capitalization (“large cap”) U.S. companies. Generally, it is more difficult for large-cap companies to pivot their strategies quickly in response to changes in their industry. In addition, because they typically are more well-established, it is rare to see large-cap companies have the high growth rates that can be seen with small-capitalization (“small cap”) companies.

7

Russell 2000® Price Return Index

This index is comprised of equity securities of small-cap U.S. companies. Generally, the securities of small-cap companies are more volatile and riskier than the securities of large-cap companies.

MSCI EAFE Price Return Index

This index is an equity index that is designed to represent the performance of large and mid-cap securities across 21 developed markets around the world but excluding the U.S. and Canada. Unique to this index (as compared to the other available Indices) are risks relating to political, social, and economic developments abroad, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. To the extent foreign securities are denominated in foreign currencies, their values may be adversely affected by changes in currency exchange rates. All of the risks of investing in foreign securities are typically increased by investing in emerging market countries. Shifts in these factors can result in this index being more volatile than other Indices.

SG Smart Climate Index

This Index provides investment exposure to the performance of large-capitalization U.S. stocks that are selected based on proprietary climate risk preparedness scores and certain environmental, social, and governance (ESG) filters. The Index provides exposure to such stocks through its underlying index, the SG Climate Transition Risk Index (the “Underlying SGI Index”).

The Index is subject to several risks, such as the following:

•Market Risk. The Index could decrease in value due to short- or long-term market downturns. Negative fluctuations in the value of the Index may be significant and unpredictable.

•Stock Risk. Stocks are subject to changes in value. Their values may be volatile. Stocks may underperform in comparison to the general financial markets, a particular financial market, or other asset classes. Actual or perceived changes in the financial condition or future prospects of a company may cause the value of its stock to decline.

•ESG Methodology Risk. The Underlying SGI Index is composed of stocks that are selected based on an ESG methodology that includes climate risk scores and ESG exclusion filters. Investors’ views about ESG matters may differ from the Underlying SGI Index’s ESG methodology. As such, the ESG methodology may not reflect the beliefs or values of any particular investor. There is no guarantee that the ESG methodology will ultimately enhance the performance of the Index. The ESG methodology could detract from the performance of the Index, as companies with lower ESG ratings may perform better than companies with higher ESG ratings over the short or long term. Due to the inherent difficulty of forecasting within complex systems and the general unpredictability of future events, there is no guarantee that the predictive climate risk models used by the Underlying SGI Index will identify stocks that will perform well if climate events occur.

Amounts invested in a Segment Option that is linked to the Index are not invested in the Index, the Underlying SGI Index, or the underlying stocks. Amounts that you invest in the Contract become assets of the Company. The assets in the Company’s General Account and the Separate Account, which the Company invests to support its payment obligations under the Contract, are not invested based on ESG factors.

•Performance Drag Risk. Theperformance of the Index will always be worse than the performance of the underlying stocks. The Index reflects deductions that reduce performance, including a negative performance adjustment equal to 1.50% and fixed replication costs equal to 0.50%, each as an annualized percentage of Index Value. In addition, the performance of the Index is reduced by assumed costs of borrowing equal to the U.S. Federal Funds Rate. Without these deductions, the performance of the Index over any one year period would be higher by approximately 2.00% plus the U.S. Federal Funds Rate. While these deductions are not charges under the Contract, they result in lower Index Values and may therefore negatively impact the performance of your Contract.

•Large-Cap Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market

8

cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

•Index Disruption Risk. Disruptive and extraordinary events could impair the operation of the Index or the Underlying SGI Index. For example, these events could relate to the unavailability of necessary data to apply the ESG methodology, an insufficient number of eligible stocks, or the termination or breach of a third-party licensing agreement. Should a disruptive or extraordinary event occur, the index provider may take any actions permitted by the index rules, such as postponing calculations or rebalances, adjusting the terms of an index to preserve its economic characteristics, restating index values, or discontinuing the index.

•New Index Risk. The Index and the Underlying SGI Index have limited performance histories. Generally, there is less publicly available information about the Index and the Underlying SGI Index compared to more established market indexes. Inquiries regarding the Index or the Underlying SGI Index should be directed to our Administrative Office or your financial intermediary.

For more detailed information about this and the other available Indices, see APPENDIX A - INDEX DISCLOSURES.

Liquidity Risk

Liquidity Risk Generally

This Contract is not suitable as a short-term savings vehicle and is not appropriate if you need ready access to cash. The benefits of tax deferral and allocation to Segment Options for the full Segment Terms are better for investors with long investment time horizons. Surrender charges apply for up to six years after the Total Premium Payment and these charges will reduce the value of your Contract if you withdraw money during that time. While the Contract provides for up to a 10% free surrender amount, such a Surrender still would be subject to a Bond Adjustment and Equity Adjustment. There also may be adverse tax consequences if you take early withdrawals from the Contract.

Limits on Transfers

The restrictions applicable to Transfers also creates liquidity risk. You are only able to make Transfers of Accumulated Value among the various Segment Options at the end of a Segment Term. This significantly limits your ability to react to changes in market conditions during Segment Terms. Your Transfer requests must be received by us at least two Valuation Days prior to the end of a Segment Term. If we do not receive a Transfer request prior to those two Business Days, your Transfer will not occur until the next following Segment Start Date. If you fail to Transfer Index-Linked Accumulated Value at the end of a Segment Term and do not wish to remain invested in a particular Index-Linked Segment Option for another Segment Term, you will need to take a full withdrawal of the related Accumulated Value. Withdrawing all or some of the Accumulated Value may cause you to incur Surrender Charges, negative adjustments to certain values under your Contract, and negative tax consequences, as discussed in this section. For additional information, see 8. OPTIONS AT END OF SEGMENT TERM.

See "Segment Interim Value Risk" below for information on how liquidity risks relate to our Interim Value calculation.

Consequences of Withdrawals/Surrenders Generally

There is a risk of loss of principal, previously credited interest and other earnings if you take a full or partial withdrawal from your Contract during the first six Contract Years where a Surrender Charge would be deducted. This risk also applies if you are invested in an Indexed-Linked Segment Option where the Index is performing positively as of the date of your withdrawal. If you set up scheduled withdrawals, your exposure to these risks will repeat as long as the scheduled withdrawals continue.

We may defer payments under this Contract for up to six months if the insurance regulatory authority of the state in which we issued the Contract approves such deferral.

For additional information, see 10. WITHDRAWALS.

Insurance Company Risks

Our General Account assets support the guarantees under the Contract and are subject to the claims of our creditors. As such, the guarantees under the Contract are subject to our financial strength and claims-paying ability. There is a risk that we may default on those guarantees. You need to consider our financial strength and claims-paying ability in meeting the guarantees under the Contract. You may obtain information on our financial condition by reviewing our financial statements included in this prospectus. Additionally, information concerning our business and operations is set forth under the section titled “Management’s Discussion and Analysis." More information about the Company, including its financial strength ratings, can be found by visiting https://investors.principal.com/investor-relations/our-business/credit-ratings/default.aspx. The assets in Principal Life Insurance Company Separate Account [to be added by amendment] are not subject to our creditors.

Segment Interim Value Risk

On each Valuation Day of the Segment Term, other than the first and last day, we determine the Segment Interim Value for each Indexed-Linked Segment Option. In order to calculate your Segment Interim Value, we apply a formula that is not directly tied to the actual performance of the applicable Index. Instead, we calculate it by determining the value of hypothetical investments and derivatives that we may or may not actually hold. This means that even if the Index has performed positively, it is possible that the Segment Interim Value may have decreased. For more information and to see how we calculate the Segment Interim Value, see APPENDIX B - SEGMENT INTERIM VALUE EXAMPLES.

If you allocate Accumulated Value to an Index-Linked Segment Option, Segment Credits will not be credited to your Accumulated Value in the particular Segment Option until the end of the Segment Term. Amounts withdrawn from an Index-Linked Segment Option prior to the end of a Segment Term will not have a Segment Credit applied to it. This includes Accumulated Value being applied to pay a death benefit or to an Annuitization option during a Segment Term. Except for the first and last Valuation Day of a Segment Term, your Segment Interim Value is the amount available for withdrawals, Annuitization and death benefits (collectively, “Surrenders”). There is risk that this Segment Interim Value could be less than your original Premium Payment even if the applicable Index has been performing positively.

Negative adjustments to the Crediting Base because of a Surrender are generally proportional and always negative. As a result, application of a negative adjustment will result in a lower Segment Interim Value. Also, a negative adjustment will result in less gain or more loss, as applicable, at the end of a Crediting Period. A negative adjustment could be greater than the amount Surrendered or deducted.

Buffer and Floor Rate Risk

The Buffer or Floor Rate that is applicable to a Segment Option only provides you with limited protection. In other words, you could lose a significant amount of your Total Premium Payment, previously credited interest and prior earnings under the Contract. In extreme circumstances, for Index-Linked Segment Options it is theoretically possible the total loss could be 100% (i.e., a complete loss of your Total Premium Payment, previously credited interest and any prior earnings).

You also bear the risk that continued negative Index Changes may result in zero or negative Segment Credits being credited to your Accumulated Value over multiple Segment Terms. If an Index-Linked Segment Option is credited with negative Segment Credits for multiple Segment Terms, the cumulative loss may exceed the stated limit of the Buffer Rate or Floor Rate for any single Segment Term. For additional information, see 7. INDEX-LINKED SEGMENT OPTION MECHANICS.

For withdrawals, Annuitizations and death benefits that occur during a Segment Term, you or your beneficiaries (as applicable) will not receive the full protection of the Buffer Rate or Floor Rate in the calculation of the Segment Interim Value. In order to receive the full protection, the particular transaction must occur on the Segment End Date.

Cap Rate and Participation Rate Risk

If you choose to allocate amounts to an Index-Linked Segment Option subject to a Cap Rate, the Cap Rate limits the positive Index Change, if any, that may be credited to your Contract for a given Segment Term. The Cap Rates do not guarantee a certain amount of Segment Return. The Segment Return for an Index-Linked Segment Option may be less than the positive return of the Index because any positive return of the respective Index is subject to a maximum in the form of a Cap Rate.

10

The Cap Rates benefit the Company when Index performance is positive at a rate that is higher than the applicable Cap Rate because the Cap Rate limits the amount of positive Segment Return that we may be obligated to credit for any Segment Term. We set the Cap Rates at our discretion. You bear the risk that we will not set the Cap Rates higher than 0.50%.

If you choose to allocate amounts to an Index-Linked Segment Option subject to a Participation Rate, at the end of the Segment Term, your participation in any positive Index performance will be limited to a percentage of the positive Index performance. That percentage will equal the Participation Rate.

The Participation Rate limits the positive Index Change, if any, that may be credited to your Contract for a given Segment Term. The Segment Return for an Index-Linked Segment Option subject to a Participation Rate will be less than the positive return of the Index. We set the Participation Rates at our discretion. You bear the risk that we will not set the Participation Rates higher than 5.00%. If, in addition to having a Participation Rate, the Index-Linked Segment Option also has a Cap Rate, you will not participate in any positive Index performance in excess of the Cap Rate.

For additional information, see 7. INDEX-LINKED SEGMENT OPTION MECHANICS.

Segment Lock-In Risk

If you exercise a Segment Lock-In, the Segment Credit you receive may be lower than the Segment Credit you would have received on the Segment End Date if you hadn’t exercised the Segment Lock-In. You also may receive less than the full protection of the Buffer Rate or Floor Rate (as applicable).

At the time you exercise a Segment Lock-In, you will not know the locked-in Equity Adjustment in advance. If you submit a Segment Lock-In request, the locked-in Equity Adjustment may be lower or higher than the Equity Adjustment that was last calculated before you submitted your request. If you establish Lock-In Thresholds, you will not know the locked-in Equity Adjustment in advance, although the locked-in Equity Adjustment will be at least equal to the upper threshold or lower threshold, as applicable.

We will not provide advice or notify you regarding whether you should exercise the Segment Lock-In features or the optimal time for doing so. We will not warn you if you exercise the Segment Lock-In features at a sub-optimal time. We are not responsible for any losses related to your decision whether or not to exercise the Segment Lock-In features.

Once a Segment Lock-In is executed, it is irrevocable for that Segment Term. A lock-in will not be applied retroactively and can only be exercised for the entire Segment Option. A Segment Lock-In may only be exercised once per Segment Term for each Index-Linked Segment Option.

For additional information, see 7. INDEX-LINKED SEGMENT OPTION MECHANICS - Segment Lock-In Feature.

Segment Option and Index Availability Risk

There is no guarantee that any particular Segment Option or Index will be available during the entire period that you own your Contract. We may replace an Index if it is discontinued or if there is a substantial change in the calculation of the Index, or if hedging instruments become difficult to acquire or the cost of hedging becomes excessive. If we substitute an Index, the performance of the new Index may differ from the original Index. This may negatively affect the Segment Credit you earn during the Segment Term or the Segment Interim Values that you can lock-in under the Segment Lock-In feature. We may replace an Index at any time during a Segment Term; however, we will notify you in writing at least 30 days prior to replacing an Index. If we replace an Index, this does not cause a change in the Cap, Participation, Floor or Buffer Rates, as applicable. You will have no right to reject the replacement of an Index, and you will not be permitted to Transfer Segment Interim Values until the end of the applicable Segment Term even if we replace the Index during such Segment Term. The new Index and the replaced Index (which you may have previously chosen) may not be similar with respect to their component securities or other instruments, although we will attempt to select a new Index that is similar to the old Index. At the end of the Segment Term, you may Transfer your Segment Value to another Segment Option or to a Fixed Segment Option without charge. If you do not want to remain invested in the relevant Segment Option for the remainder of the Segment Term, your only option will be to withdraw the related Segment Interim Value, which may cause you to incur Surrender Charges, negative adjustments to certain values under your Contract, and negative tax consequences, as discussed in this section.

Changes to the Cap and Participation Rates, if any, occur at the beginning of the next Segment Term. We will provide written notice at least 15 days prior to each Segment Term instructing you how to obtain the Cap and

11

Participation Rates for the next Segment Term. You do not have the right to reject any new Cap or Participation Rates for the next Segment Term. If you do not like a new Cap or Participation Rate for a particular Segment Option, at the end of the current Segment Term, you may Transfer your Segment Value to another Segment Option or to Fixed Segment Option without charge. If you do not want to invest in any investment option under the Contract, your only option will be to surrender your Contract. Surrendering your Contract may cause you to incur Surrender Charges, negative adjustments to certain values under the Contract, and may have negative tax consequences, as discussed in this section.

We may also add or remove an Index during the time that you own the Contract. We will not substitute any Index until the new Index has received any necessary regulatory clearances. Any addition, substitution, or removal of an Index-Linked Segment Option or Index will be communicated to you in writing. If we add or remove an Index (as opposed to replacing an Index), the changes will not be effective for your Contract until the start of the next Segment Term. Adding or removing an Index does not cause a change in the Floor or Buffer Rates, as applicable. Any Index-Linked Segment Option based on the performance of the newly added Index may have a new Cap and Participation Rate.

You should evaluate whether our ability to make the changes described above, and your ability to react to such changes, are appropriate based on your investment goals. When such changes occur, you should also evaluate whether those changes are appropriate based on your investment goals and, if not, you should evaluate your options under the Contract, which may be limited and may have negative consequences associated with them, as described in this section.

For additional information, see 7. INDEX-LINKED SEGMENT OPTION MECHANICS - Discontinuation or Substitution of an Index and 8. OPTIONS AT END OF SEGMENT TERM.

Risks Affecting Our Administration of Your Contract

Our operations and/or the activities and operations of our service providers and business partners are subject to certain risks that are beyond our control, including systems failures, cyber-attacks, and pandemics (and similar events). These risks are not unique to the Company and they could materially impact our ability to administer the Contract.

The Company is highly dependent upon its computer systems and those of its business partners. This makes the Company potentially susceptible to operational and information security risks resulting from a cyber-attack. These risks include direct risks, such as theft, misuse, corruption and destruction of data maintained by the Company, and indirect risks, such as denial of service attacks on service provider websites and other operational disruptions that impede our ability to electronically interact with service providers. Operational disruptions and system failures also could occur based on other natural or man-made events, which could have similar impacts on your Contract. Although we make substantial efforts to protect our computer systems from these security risks, including internal processes and technological defenses that are preventative or detective, and other controls designed to provide multiple layers of security assurance, there can be no guarantee that we or our service providers will avoid losses affecting contracts such as the security incidents described above.

If your Contract is adversely affected as a result of the failure of our cyber-security controls, we will take reasonable steps to restore your Contract.

Q: Where is my Premium Payment held before the initial Segment Term?

Beginning on the Contract Date, your Premium Payment will be held in the Initial Holding Account. Interest will be credited on the amount held in the Initial Holding Account at a fixed rate determined at Contract issue. On the next Segment Start Date, the total amount in the Initial Holding Account will be transferred to the Segment Option(s) as described immediately below so long as we receive the Total Premium Payment at least two Valuation Days prior to the Segment Start Date. For additional information, see 5. PURCHASING THE CONTRACT.

Q: How is interest applied to my investment in a Fixed Segment Option?

Amounts allocated to a Fixed Segment Option earn interest at the applicable annual interest rate for the Segment Term. The annual interest rate declared at the beginning of the Segment Term is guaranteed until the Segment End Date. Interest will be credited on a daily basis during the Segment Term. The daily rate is calculated as [(1+Annual Interest Rate) ^ (1/365)-1].

For each Fixed Segment Option that you select for investment, the Fixed Segment Value at any time will be equal to the Accumulated Value allocated to the fixed Segment Option on the Segment Start Date, plus interest credited to that Segment Option during the Segment Term, less any amount deducted from that Segment Option during the Segment Term.

For the initial Segment Term, the annual interest rates for the Fixed Segment Options will be listed on your Data Page. We may declare different interest rates for subsequent Segment Terms. At least fifteen (15) days prior to the end of any Segment Term, we will provide notice of the annual interest rates for the Fixed Segment Options that will be available for investment.

We determine the annual interest rates for the Fixed Segment Options at our discretion. In no event will we declare an annual interest rate lower than the Guaranteed Minimum Interest Rate of 0.05%. You bear the risk that we will not credit interest for a new Segment Term at a rate greater than the Guaranteed Minimum Interest Rate.

For additional information, see 6. FIXED SEGMENT OPTION MECHANICS.

Q: How is gain or loss applied to my investment in an Index-Linked Segment Option at the end of a Segment Term?

The Crediting Base represents the value of a Segment Option on the Segment Start Date (subject to certain adjustments). The Segment Credit is calculated and applied to the Crediting Base only on the Segment End Date. Segment Credits could be negative, meaning you could lose principal and/or prior earnings.

On each applicable Segment End Date, a calculation is performed to determine the Segment Credit that will change the respective Segment Option’s Crediting Base. The calculation involves a review of the change in the Index Value for the particular Segment Option. The change in the Index Value is the difference between the Index Value on the Segment End Date and the Index Value on the Segment Start Date divided by the Index Value on the Segment Start Date. If the change in the Index Value is positive, the Segment Return on the Segment End Date will be the change in the Index Value multiplied by the Participation Rate up to the Cap Rate (as applicable). If the change in the Index Value is negative, the negative Segment Return will be subject to the Buffer or Floor Rate (as applicable). With the Buffer Segment Option, the Company will absorb losses for the applicable Segment Option up to the Buffer Rate and you will be responsible for any loss greater than the Buffer Rate. With the Floor Segment Option, the Company will absorb losses for the applicable Segment Option greater than the Floor Rate and you will be responsible for any loss up to the Floor Rate.

For additional information, see 7. INDEX-LINKED SEGMENT OPTION MECHANICS.

14

Q: How is the value of my investment in an Index-Linked Segment Option calculated before the end of a Segment Term?

The Accumulated Value is the sum of the Segment Interim Values, Segment Values, and Fixed Segment Values, as applicable, plus the total value of any allocation to the Initial Holding Account. The Surrender Value is the Accumulated Value adjusted for any applicable Bond Adjustment and minus any applicable Surrender Charges and other fees (if any).

For additional information, see 7. INDEX-LINKED SEGMENT OPTION MECHANICS.    

Q: At the end of a Segment Term for a Segment Option, what are my options under the Contract?

    At the end of a Segment Term for any Segment Option, the following options are available to you:

•You may reinvest your Accumulated Value allocated to the ended Segment Option in the same Segment Option for another Segment Term if the Segment Option is still available. Please note, the Cap Rate, Participation Rate, or annual interest rate we declare for the new Segment Term may differ (higher or lower) from the previous Segment Term, subject to the guaranteed limits described in this prospectus.

•You may Transfer your Accumulated Value allocated to the ended Segment Option to any other Segment Option that is available for investment. Transfers from a Segment Option are only allowed on the Segment End Date. If you wish to Transfer, you must Notify us at least two Valuation Days prior to the Segment End Date.

•You may withdraw or Annuitize your Accumulated Value allocated to the ended Segment Option, subject to the terms and conditions described in this prospectus. Withdrawals and Annuitization are not restricted to Segment End Dates, but amounts withdrawn or Annuitized from a Segment Option on its Segment End Date will not be based on a Segment Interim Value. However, such withdrawals will still be subject to the Bond Adjustment and may be subject to surrender charges (surrender charges do not apply upon Annuitization).

For additional information, see 8. OPTIONS AT END OF SEGMENT TERM, 10. WITHDRAWALS and 13. ANNUITIZATION.

Q: Prior to the end of a Segment Term for a Segment Option, what are my options under the Contract?

You may withdraw all or a portion of the Contract at any time before the Annuitization Date. Types of Surrenders are full withdrawals of the Contract, partial withdrawals, payment of a death benefit and Annuitizations. The Surrender Value is: subject to a Bond Adjustment being applied, which could be negative; and reduced by any applicable Surrender Charge and fee(s) (Contract fees and/or prorated share of the charge(s) for optional rider(s)). Full and partial withdrawals may be subject to taxes and to a separate 10% federal tax penalty if made before the Owner is 59½ years old. For additional information, see 10. WITHDRAWALS.

There is a Free Surrender Amount under your Contract for Surrenders up to 10% of the Total Premium Payment decreased by any partial Surrenders and/or partial Annuitization made since the last Contract Anniversary. Subject to these restrictions, you will not incur a Surrender Charge for any withdrawals less than or equal to the Free Surrender Amount but the withdrawal will be subject to the Equity Adjustment and Bond Adjustment. For additional information, see 4. FEES AND CHARGES - Deferred Sales Load ("Surrender Charger") - Free Surrender Amount.

Q: What is the optional Rate Enhancement Rider?

The Rate Enhancement Rider is an optional benefit that can only be elected at the time the Contract is issued. The Rate Enhancement Rider effective date is the same as the Contract Date.

The Rate Enhancement Rider provides an increased Participation Rate and/or Cap Rate on the Index-Linked Segment Options to which you have amounts allocated. The increased Participation Rate and/or Cap Rate (as applicable) are shown on your Contract’s Data Page.

The annual charge for the Rate Enhancement Rider is 0.95%, which is deducted daily. If the Rate Enhancement Rider is terminated, the charge for the Rate Enhancement Rider also is terminated. The Rate

15

Enhancement Rider can only be terminated on a Segment Anniversary divisible by six.

For additional information, see 7. INDEX-LINKED SEGMENT OPTION MECHANICS - Optional Rate Enhancement Rider.

Q: What is the Bond Adjustment?

The Bond Adjustment is an adjustment (which could be positive, negative, or equal to zero) to the amount Surrendered based on the change in the fair value of the hypothetical fixed income assets supporting our financial obligations under the Contract.

For additional information, see 9. CONTRACT VALUES - Bond Adjustment.

Q: What are the Contract’s lock-in features?

The Contract’s lock-in features allow you to lock in an Index-Linked Segment Option’s Equity Adjustment prior to the Segment End Date. These lock-in features are available with all of the Index-Linked Segment Options under the Contract. There is no additional charge for these lock-in features.

The lock-in features may be of interest to people who:

•Are interested in eliminating some of the uncertainty regarding Index performance for the remainder of a Segment Term; or

•Are wanting to potentially limit the impact of a negative Segment Credit they may otherwise receive.

Upon exercising a lock-in, on the Segment End Date, the Owner will receive a Segment Credit equal to the locked-in Equity Adjustment. Between the date of lock-in and the Segment End Date, the Segment Interim Value will be calculated using the locked-in Equity Adjustment. If a lock-in has been exercised and the current Segment End Date is later than the next Segment Anniversary, the Segment End Date is moved up to the next Segment Anniversary.

For additional information, see 7. INDEX-LINKED SEGMENT OPTION MECHANICS - Segment Lock-In Feature.

Q: What fees and charges apply under the Contract?

Your Contract is subject to certain fees and charges. There is a charge (“Surrender Charge”) that applies if you withdraw money from your Contract during the first six Contract Years. The maximum Surrender charge is 8% of the amount withdrawn, declining down to 0% after the sixth Contract Anniversary.

If you have the Rate Enhancement Rider as part of your Contract, there is a separate rider fee for having this benefit. This rider is an optional benefit under this Contract. The annual charge for this rider is 0.95%, which is deducted daily from the Crediting Base. The charge will only be charged for the Index-Linked Segment Options.

For additional information, see 4. FEES AND CHARGES.

Q: What are the Contract’s Annuitization benefits?

Any time after the second Contract Year, you may Annuitize your Contract by electing to receive payments under an annuity benefit payment option. The amount you can apply to the annuity benefit payment option is the Accumulated Value, adjusted by the Bond Adjustment, which could be a negative adjustment. You may elect to Annuitize the entire Contract (full Annuitization) or a portion of your Contract (partial Annuitization). The Maximum Annuitization Date is shown on the Data Page and is generally the Contract Anniversary following the Annuitant’s age 95. If Joint Annuitants are named on the application, the Maximum Annuitization Date will be set based on the age of the older Joint Annuitant.

For additional information, see 13. ANNUITIZATION.

16

Q: What are the Contract’s death benefits?

If the age of the oldest Owner on the date the application is signed is 79 or younger, the death benefit is equal to the greater of 1 or 2 where:

1. Is the Accumulated Value, subject to the Bond Adjustment, on the date we receive the proof of death and all required documents in Good Order; and

2. Is the Total Premium Payment minus an adjustment (as described below) for each partial Surrender (and any applicable Surrender Charge and fees) and an adjustment for each partial Annuitization made prior to the date we receive the poof of death and all required documents.

The adjustment for each partial Surrender (and any applicable Surrender Charges and fees) and for each partial Annuitization will reduce the death benefit in the same proportion that the Accumulated Value was reduced on the date of the partial Surrender or partial Annuitization. The adjustment for partial Surrenders is equal to (1 divided by 2) multiplied by 3, where:

1. Is the amount of the partial Surrender (and any applicable Surrender Charges and fees) or the amount of the partial Annuitization; and

2. Is the Accumulated Value immediately prior to the partial Surrender or partial Annuitization; and

3. Is the Total Premium Payment adjusted for prior partial Surrenders and partial Annuitizations immediately prior to the current partial Surrender or partial Annuitization.

If the age of the oldest Owner on the date the application is signed is 80 or older, the death benefit is equal to the Accumulated Value, subject to the Bond Adjustment (which could be negative), on the date we receive the proof of death and all required documents in Good Order.

If the Owner or any Joint Owner dies prior to the Annuitization Date, we will pay the death benefit upon our receipt of required documents and Notice, in Good Order, including due proof of death. Proof of death includes a copy of a death certificate, a certified copy of a court order, a written statement by a medical doctor, or other proof satisfactory to us.

The Accumulated Value will remain invested in the Segment Options until the Valuation Day on which we receive the required documents in Good Order. If more than one beneficiary is named, each beneficiary's portion of the death benefit will remain invested in the Segment Options until the Valuation Day on which we receive the required documents for that beneficiary.

We will pay interest on the death benefit from the first day the Accumulated Value is no longer invested in the Segment Options until payment is made. We will determine the rate of interest, which will not be less than the interest rate required by the applicable state's law.

For additional information, see 11. DEATH BENEFIT.

Q: How should I contact Principal Life?

If you have any questions, you can contact Principal Life Insurance Company at 1-800-852-4450 between the hours of 7 a.m. and 6 p.m. Central Time

Q: Does the Contract Have Any Optional Benefits

The Rate Enhancement Rider is an optional benefit that can only be elected at the time the Contract is issued. The Rate Enhancement Rider provides an increased Participation Rate and/or Cap Rate on the Index-Linked Segment Options. The annual charge for this rider is 0.95%, which is deducted daily. For additional information, see 7. INDEX-LINKED SEGMENT OPTION MECHANICS - Optional Rate Enhancement Rider.

17

4.     FEES AND CHARGES

Certain charges are deducted under the Contract. If the charge is not sufficient to cover our costs, we bear the loss. If the expense is more than our costs, the excess is profit to the Company. We expect a profit from all the fees and charges listed below, except Premium Tax.

Deferred Sales Load (“Surrender Charge”)

No sales charge is collected or deducted when the Total Premium Payment is applied under the Contract. A Surrender Charge is assessed on certain full or partial withdrawals. The Surrender Charge would be deducted from the Accumulated Value after the Bond Adjustment is applied.

The Surrender Charge would be deducted from the Accumulated Value remaining in the Segment Option(s) from which the amount is withdrawn. If you specify the percentages to be withdrawn from each Segment Option as part of a partial withdrawal request, those allocation percentages will also apply to the Surrender Charges. If you do not provide us with specific percentages, the charge is deducted in the same proportion as the Accumulated Value in the Segment Options.

The amounts we receive from the Surrender Charge are used to cover some of the expenses of the sale of the Contract (primarily commissions, as well as other promotional or distribution expenses). If the Surrender Charge collected is not enough to cover the actual costs of distribution, the costs are paid from the Company’s General Account assets instead of charging you any additional amount.

The maximum Surrender Charge is 8% of the amount withdrawn, declining down to 0% after the sixth Contract Anniversary as follows:

SURRENDER CHARGE TABLE
Contract Year	Surrender Charge
1	8.00%
2	8.00%
3	7.00%
4	6.00%
5	5.00%
6	4.00%
7+	0.00%

Surrender Charge Example

The following example shows you how the new total Crediting Base is calculated after a partial withdrawal is taken. For purposes of the example, the following assumptions were used:

Total Premium Payment: $100,000.00

Total Crediting Base: $100,000.00

Equity Adjustment Percentage: 5.22%

Equity Adjustment Amount: $5,220.00

Accumulated Value prior to withdrawal: $105,220.00

Free Withdrawal Amount: $10,000.00 (which is the product of $100,000.00 X 10%)

Partial Withdrawal Amount: $20,000.00

In order to determine the Total Crediting Base following a $20,000 partial withdrawal, the following steps are taken:

•The portion of the Crediting Base Surrendered is $19,007.79. This was calculated by dividing the partial withdrawal amount ($20,000.00) by the Total Accumulated Value immediately prior to the partial withdrawal ($105,220.00) and multiplying the result by the Total Crediting Base immediately prior to the partial withdrawal ($100,000.00).

18

•The Bond Adjustment amount is negative $296.52. For this example we assumed the Bond Adjustment percentage was negative 1.56%. The Bond Adjustment amount was calculated by multiplying the portion of the Crediting Base Surrendered ($19,007.79) times the Bond Adjustment percentage (negative 1.56%).

•The Surrender Charge amount is $776.28. For this example we assumed a Surrender Charge percentage of 8.00%, which would be the case if the partial withdrawal occurred during the first or second Contract Year. The Surrender Charge amount is calculated by subtracting the Free Surrender Amount ($10,000.00) from the withdrawal amount after Bond Adjustment ($19,703.48) and multiplying the difference by the Surrender Charge percentage (8.00%).

•The Total Crediting Base immediately following the partial withdrawal is $80,992.21. This amount is calculated by subtracting the portion of the Crediting Base Surrendered (19,007.79) from the initial Total Crediting Base ($100,000.00).

Free Surrender Amount

There is a free surrender amount available under your Contract. Subject to the limitations set forth below, you will not incur a Surrender Charge for any withdrawals less than or equal to the free surrender amount but the withdrawal will still be subject to the Bond Adjustment, which could be a negative adjustment.

The free surrender amount may be withdrawn without a Surrender Charge. This amount is the greater of (1) and (2) where:

(1) is 10% of the Total Premium Payment decreased by any partial withdrawals and/or partial Annuitizations made since the last Contract Anniversary; and

(2) is any amount distributed as a result of the Required Minimum Distribution (“RMD”) of the then current Federal Income Tax Regulation for this Contract minus any partial Surrenders and/or partial Annuitization.

Any free surrender amount not taken in a Contract Year is not added to the amount available under the free surrender amount for any following Contract Year(s).

When Surrender Charges Do Not Apply

The Surrender Charge does not apply to:

•amounts applied under an annuity benefit payment option; or

•a withdrawal amount up to the free surrender amount; or

•payment of any death benefit; or

•amounts distributed to satisfy the RMD, provided that the amount withdrawn does not exceed the minimum distribution amount that would have been calculated based on the value of this Contract alone; or

•an amount transferred from a Contract used to fund an IRA to another annuity contract issued by the Company to fund an IRA of the participant’s spouse when the distribution is made pursuant to a divorce decree.

Free Withdrawal Example

The following example shows you have the free surrender feature works.

For purposes of the example, the following assumptions were used:
Total Premium Payment	$100,000.00
Total Crediting Base	$100,000.00
Equity Adjustment Percentage	5.22%
Equity Adjustment Amount	$5,220.00
Accumulated Value prior to withdrawal	$105,220.00
Based on the above assumptions, the below numbers are calculated as described in the footnotes below the table.
Free Withdrawal Amount	$10,000.001
Withdrawal Amount	$10,000.00
Portion of Crediting Base Surrendered	$9,503.902
Bond Adjustment Percentage	-1.56%
Bond Adjustment Amount	-$148.263
Withdrawal Amount after Bond Adjustment	$9,851.74
Surrender Charge Percentage	8.00%
Surrender Charge	$0.00
Net Withdrawal Amount after Surrender Charges	$9,851.74
Total Crediting Base after Withdrawal	$80,992.214

1)Free Withdrawal Amount = $100,000.00 * 10% = $10,000.00

2)Portion of Crediting Base Surrendered = $10,000.00 / $105,220.00 * $100,000.00 = $9503.90

3)Bond Adjustment Amount = $9,503.90 * -1.56% = -$148.26

4)Surrender Charge = Max ($9,851.74 - $10,000.00, $0.00) * 8.00% = $0.00

5)Total Crediting Base after Withdrawal = $100,000.00 - $9,503.90 = $90,496.10

Waiver of Surrender Charge Rider

This rider is automatically added to the Contract at issue (subject to state approval and state variations may apply). There is no charge for this benefit.

This rider waives the Surrender Charge on withdrawals made after the first Contract Anniversary if the Owner or Annuitant has a critical need. The Segment Interim Value calculations, Bond Adjustments and negative adjustments to Crediting Base discussed in other sections of the prospectus will still apply to amounts deducted under this waiver.

A critical need is limited to confinement to a health care facility, terminal illness diagnosis, or total and permanent disability.

The benefits are available for a critical need if the following conditions are met:

•the Owner or Annuitant has a critical need; and

•the critical need did not exist before the Contract Date.

20

For purposes of this rider, the following definitions apply:

•health care facility - a licensed hospital or inpatient nursing facility providing daily medical treatment and keeping daily medical records for each patient (not primarily providing just residency or retirement care). This does not include a facility owned or operated by the Owner, Annuitant or a member of their immediate family. If the critical need is confinement to a health care facility, the confinement must continue for at least 60 consecutive days after the Contract Date and the Surrender must occur within 90 days of the confinement’s end. Notice must be provided within 90 days after confinement ends.

•terminal illness - sickness or injury that results in the Owner’s or Annuitant’s life expectancy being 12 months or less from the date notice to receive a distribution from the Contract is received by the Company.

•total and permanent disability - the Owner or Annuitant is unable to engage in any occupation for pay or profit due to sickness or injury.

Maximum Potential Loss Due to Equity Adjustment and Bond Adjustment

Before the end of a Segment Term for an Index-Linked Segment Option, if any of the following transactions occurs, the transaction will be based on the Segment Interim Value of your investment in that Index-Linked Segment Option:

•you take a full or partial withdrawal,

•you exercise the Lock-In feature,

•you Annuitize the Contract,

•the Contract’s death benefit is paid, or

•a fee or charge is deducted from that Index-Linked Segment Option.

The application of the Equity Adjustment and Bond Adjustment to such transactions could result in a loss beyond the downside protection for the Index-Linked Segment Option. In extreme circumstances, for any Index-Linked Segment Option, the total loss could be 100% (i.e., a complete loss of your principal, previously credited interest and any prior earnings).

Premium Taxes

We do not currently assess premium taxes for any Contract at issue. We reserve the right to deduct an amount to cover any premium taxes imposed by states or other jurisdictions. If we elect to begin deducting any premium taxes, we will provide you with 30 days advance written notice. Any deduction is made from either the Premium Payment when we receive it, or the Accumulated Value when you request a withdrawal (full or partial) or you request application of the Accumulated Value (full or partial) to an annuity benefit payment option. Premium taxes generally range from 0% in most states to as high as 3.50%.

Optional Benefit – Rate Enhancement Rider

The Rate Enhancement Rider is an optional benefit that can only be elected at the time the Contract is issued. The Rate Enhancement Rider provides an increased Participation Rate and/or Cap Rate on the Index-Linked Segment Options.

The annual charge for this rider is 0.95%, which is deducted daily. The charge will only be charged for the Index-Linked Segment Options. The rider charge is intended to reimburse us for the cost of providing the enhanced rates.

The charge is reflected in Segment Interim Value because it is deducted from the Crediting Base. The charge is applied against and deducted daily from the Crediting Base prior to other Contract activity (e.g., Surrender, Segment Credits) on a particular day. If you exercise a Segment Lock-In, this charge continues to be applied against and deducted from the Crediting Base.

Rate Enhancement Rider Charge Example

If your Crediting Base is $100,000.00 at the start of your Segment Term, the daily charge deducted from your Crediting Base for the rider would be $2.06 ($100,000.00 * 0.95% / 365). In that example, on the 100th day after the Segment Start Date, the Crediting Base would be $100,000.00 – ($2.06 * 100) = $99,794.00.

For more information on the Rate Enhancement Rider, please see 7. INDEX-LINKED SEGMENT OPTION MECHANICS - Optional Rate Enhancement Rider.

5.     PURCHASING THE CONTRACT

How to Buy a Contract

If you want to buy a Contract, you must submit an application and make a Premium Payment. If the application is complete, received in Good Order and meets all other regulatory and Company requirements, the Contract is issued after we receive the Total Premium Payment. We reserve the right to reject a Premium Payment that is comprised of multiple payments paid to us over a period of time. If we permit you to make multiple payments as part of your Premium Payment, the Contract will not be issued until all such payments are received. We reserve the right to hold such multiple payments in a non-interest bearing account until the date of Contract issuance.

The date the Contract is issued is the Contract Date. The Contract Date is the date used to determine Contract Years, regardless of when the Contract is delivered.

Premium Payment

•The Total Premium Payment for a Contract may not be less than $20,000 without our prior approval.

•The Premium Payment is subject to a Surrender Charge period that begins upon issuance of the Contract.

•The Premium Payment is to be made by personal or financial institution check (for example, a cashier’s check). We reserve the right to refuse a Premium Payment that we feel presents a fraud or money laundering risk. Examples of the types of Premium Payments we will not accept are cash, money orders, starter checks, travelers checks, credit card checks, and foreign checks.

•The Total Premium Payment for a Contract may not be greater than $2,000,000 (maximum premium limit) without our prior approval. For further information, please call 1-800-852-4450.

•We reserve the right to treat all of your and/or your spouse’s Principal index-linked deferred annuity contracts as one contract for purposes of determining whether you have exceeded the maximum premium limit (without Home Office approval).

•This Contract is a single premium index-linked deferred annuity. After the Total Premium Payment is added to the Contract at Contract issuance, no additional Premium Payments will be accepted.

Initial Holding Account

Beginning on the Contract Date, your Premium Payment will be held in the Initial Holding Account. Interest will be credited on the amount held in the Initial Holding Account at a fixed rate determined at Contract issue. The Guaranteed Minimum Interest Rate for the Initial Holding Account will be 0.05%.

The Segment Start Dates will be the 9th and the 23rd of each month. On the next Segment Start Date, the total amount in the Initial Holding Account will be transferred to the Segment Option(s) as described immediately below so long as we receive the Total Premium Payment at least two Valuation Days prior to the Segment Start Date. If the Total Premium Payment is not received at least two Valuation Days prior to a Segment Start Date, the Total Premium Payment will remain in the Initial Holding Account until the following Segment Start Date. For example, if we receive your application in Good Order and your Total Premium Payment on the 8th of the month, your Segment Start Date will be the 23rd of that month because your application and Total Premium Payment were not received two or more Valuation Days prior to the 9th. In that situation the Total Premium Payment would remain in the Initial Holding Account until the 23rd of that month.

.Allocating to the Segment Options

•On your application, you direct how the amount transferred out of the Initial Holding Account will be allocated to the Segment Option(s).

•A complete list of the Segment Options and available Segment Terms may be found in 3. SUMMARY.

•Allocations must be in percentages.

•Percentages must be in whole numbers and total 100%.

•Once an amount is allocated to a particular Segment Option, the amount cannot be transferred until the end of the Segment Term for that particular Segment Option.

22

Contract Owner Rights

During the accumulation period, you have all rights to the benefits under the Contract. The Annuitant and any Joint Annuitant (if not the Owner or Joint Owner, respectively) do not have any rights to the Contract. All of your rights of ownership cease upon your death. At that point the death benefit will become payable according to your benefit instructions.

During the Annuitization period you are still the only person with material rights to the Contract. For more details on the Annuitization period, see ___. After the death of the Owner the primary beneficiary(ies) have the rights to the death benefit, if any.

If your Contract is part of a qualified plan, IRA, SEP, or SIMPLE-IRA, you may not change either the Owner or the Annuitant.

You may change the Owner and/or Annuitant of your Non-qualified Contract at any time. Your request must be in writing and approved by us. After approval, the change is effective as of the date you signed the request for change. We reserve the right to require that you send us the Contract so that we can record the change.

If an Annuitant who is not an Owner dies while the Contract is in force, a new Annuitant may be named unless the Owner is a corporation, trust or other entity.

While this Contract is in force, you have the right to name or change a beneficiary. This may be done as part of the application process or by sending us a written request. Unless you have named an irrevocable beneficiary, you may change your beneficiary designation by sending us Notice.

Right to Examine the Contract (Free Look)

It is important to us that you are satisfied with the purchase of your Contract. Under state law, you have the right to return the Contract for any reason during the examination offer period (a “free look”). The examination offer period is the later of 15 days after the Contract is delivered to you, or such later date as specified by applicable state law. For a state-by-state description of material variations of this Contract, see Appendix _____.

If you cancel your Contract under the free look provision, you will receive your total Contract Accumulated Value or the Premium Payment, if required by state law. The Contract Accumulated Value would be subject to the Bond Adjustment and Segment Interim Value calculation if your Premium Payment is allocated to a Segment Option. If you receive the Contract Accumulated Value, you assume the risk of any drop in Segment Interim Value on Premium Payment allocated to the Index-Linked Segment Options.

Although we currently allocate to the Segment Options prior to the end of the examination offer period (after holding the money in the Initial Holding Account), during times of economic uncertainty and with prior notice to you, we may exercise our right to keep the Total Premium Payment in the Initial Holding Account during the entire examination offer period. If your Total Premium Payment remains in the Initial Holding Account and the free look is exercised, you will receive the sum of the Total Premium Payment and any previously credited interest.

If your Total Premium Payment remains in the Initial Holding Account for the entire free look period and you don’t cancel the Contract during that time, after the free look period ends your Accumulated Value will be allocated to the Segment Options you select on the next Segment Start Date.

The amount of your refund and the length of the free look period may depend on whether your Contract is a replacement of another insurance or annuity contract. Generally, for Contracts issued as a replacement, this period is 30 days. If your Contract is an IRA or Roth IRA and you cancel within the first 7 days, you will receive the greater of:

•The Total Premium Payment made, plus any previously credited interest; or

•Your Accumulated Value, plus any premium tax charge deducted, less any applicable federal and state income tax withholding and, depending on the state in which the Contract was issued, any applicable fees and charges.

After the first 7 days, your state's law will determine the amount you will receive (as described earlier in this provision).

To exercise your free look, you must send the Contract and a written request to us postmarked before the close of business on the last day of the examination offer period. If you properly exercise your free look, we will cancel the Contract.

23

You may obtain more specific information regarding the free look from your registered representative or by calling us at 1-800-852-4450.

Distribution of the Contract

[To be added by amendment] (the "principal underwriter") serves as principal underwriter for the contracts. We have entered into an underwriting agreement with the principal underwriter that covers distribution of the contracts. The principal underwriter is registered as a broker-dealer with the SEC under the 1934 Act, and with the securities commissions in the states in which it operates and is a member of the Financial Industry Regulatory Authority (“FINRA”). The principal underwriter is a member of the Securities Investors Protection Corporation. You may contact FINRA by calling 1-800-289-9999 or online at www.finra.org for information about the principal underwriter as well as your broker-dealer and their respective registered persons.

With the exception of New York, the Company intends to offer the Contract in all jurisdictions where it is licensed to do business and where the Contract is approved.

The principal underwriter may perform various administrative services on our behalf. We may fund certain of the principal underwriter’s operating and other expenses, including overhead, legal and accounting fees, training, compensation and other expenses associated with the contracts. Financial professionals associated with the principal underwrtier and their managers are also eligible for various benefits.

We offer the contracts on a continuous basis. Contracts are sold only by licensed financial professionals in
those states where the Contracts may be lawfully sold. The principal underwriter and the Company enter into selling agreements with unaffiliated broker-dealer firms (the “selling broker-dealers”) for the sale of the contracts through those firms and their financial professionals. The financial professionals will be registered representatives of the selling broker-dealers that are registered as broker-dealers under the 1934 Act and members of FINRA.

The Company and/or the principal underwriter pay compensation to broker-dealers, financial institutions, and other parties (“Financial Intermediaries”) for the sale of contracts according to schedules in the selling agreements and other agreements reached between the Company, the principal underwriter and the Financial Intermediaries. Such compensation generally consists of commissions on premiums paid on the Contract.

The amount and timing of commissions paid to selling broker-dealers may vary depending on the selling agreements and the contract sold but will not be more than 6.5% of the Total Premium Payment. Some selling broker-dealers may elect to receive a smaller amount of commission at the time of the sale and an ongoing trail commission for as long as the Contract remains in effect or as agreed in the selling agreement. We may pay or allow other promotional incentives or payments to selling broker-dealers in the form of cash or other compensation to the extent permitted by FINRA rules and other applicable laws and regulations.

The financial professionals who solicit sales of the contracts typically receive a portion of the compensation paid to the selling broker-dealers in the form of commissions or other compensation, depending on the agreement between the selling broker-dealer and the financial professional. The financial professionals may also be eligible for various cash benefits, such as bonuses, insurance benefits, and financing arrangements, and non-cash items. Non-cash items include conferences seminars and trips (including travel, lodging and meals in connection therewith), entertainment, merchandise, priority operations support, preferred programs, and other similar items. Sales of the contracts may help financial professionals qualify for such benefits.

Commissions and other incentives or payments described above are not charged directly to you. We intend to recoup commission and other expenses through fees and charges deducted under the Contract.

6. FIXED SEGMENT OPTION MECHANICS

There is only one Fixed Segment Option for this Contract. This Fixed Segment Option has a one-year Segment Term.

Amounts allocated to a Fixed Segment Option earn interest at the applicable annual interest rate for the Segment Term. The annual interest rate declared at the beginning of the Segment Term is guaranteed until the Segment End Date. Interest will be credited on a daily basis during the Segment Term. The daily rate is calculated as [(1+Annual Interest Rate) ^ (1/365)-1].

24

If you allocate Accumulated Value to the Fixed Segment Option, the Fixed Segment Value at any time will be equal to the Accumulated Value allocated to the Segment Option on the Segment Start Date, plus interest credited to that Segment Option during the Segment Term, less any amount deducted from that Segment Option during the Segment Term.

For the initial Segment Term, the annual interest rates for the Fixed Segment Options will be listed on your Data Page. We may declare different interest rates for subsequent Segment Terms. At least fifteen (15) days prior to the end of any Segment Term, we will provide notice of the annual interest rates for the Fixed Segment Options that will be available for investment.

We determine the annual interest rates for the Fixed Segment Options at our discretion. In no event will we declare an annual interest rate lower than the Guaranteed Minimum Interest Rate of 0.05%. You bear the risk that we will not credit interest for a new Segment Term at a rate greater than the Guaranteed Minimum Interest Rate.

We reserve the right to add and remove Fixed Segment Options as available investment options. There is no guarantee that any Fixed Segment Option will always be available for investment in the future. If we remove a Fixed Segment Option, it will be closed such that no reinvestments or Transfers will be allowed into that Segment Option. If you are currently invested in a Fixed Segment Option that has been removed, you may remain in that Segment Option until the end of the Fixed Segment Term.

7. INDEX-LINKED SEGMENT OPTION MECHANICS

General Information

The available Index-Linked Segment Options for this Contract are shown in 3. SUMMARY as part of the answer to the "What are the available Segment Options" question.

Index-Linked Segment Options are Buffer Segment Options and Floor Segment Options. These investment options receive Segment Credits based on the performance of a linked Index and applying a Buffer Rate, Floor Rate, Cap Rate and/or Participation Rate, as applicable. Segment Terms range from one to six years and are linked to one of the following Indices: S&P 500® Price Return Index (SPX); Russell 2000® Price Return Index (RTY); MSCI EAFE Price Return Index (MXEA); and SG Smart Climate Index (SGIXSMAC).

Information About the Indices

S&P 500® Price Return Index (SPX)

The S&P 500® Price Return Index was established by Standard & Poor’s. The S&P 500® Price Return Index includes 500 large cap stocks from leading companies in leading industries of the U.S. economy, capturing 75% coverage of U.S. equities. The S&P 500® Price Return Index does not include dividends declared by any of the companies included in this Index.

Russell 2000® Price Return Index (RTY)

The Russell 2000® Price Return Index was established by Russell Investments. The Russell 2000® Price Return Index measures the performance of the small-cap segment of the U.S. equity universe. The Russell 2000® Price Return Index is a subset of the Russell 3000® Index representing appropriately 10% of the total market capitalization of that Index. It includes approximately 2,000 of the smallest securities based on a combination of their market cap and current index membership. The Russell 2000® Price Return Index does not include dividends declared by any of the companies included in this Index.

MSCI EAFE Price Return Index (MXEA)

The MSCI EAFE Price Return Index was established by MSCI. The MSCI EAFE Price Return Index is a free float-adjusted market capitalization index that is designed to measure the equity market performance of developed markets, excluding the U.S. and Canada. As of the date of this prospectus the MSCI EAFE Price Return Index consisted of the following 22 developed market country indices: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, and the United Kingdom. The MSCI EAFE Price Return Index does not include dividends declared by any of the companies included in this Index.

25

SG Smart Climate Index

The SG Smart Climate Index (Bloomberg Ticker: SGIXSMAC) is a rules-based index that aims to provide investment exposure to the performance of stocks of U.S. large-capitalization companies that are selected based on proprietary climate risk preparedness scores and certain environmental, social, and governance (ESG) exclusion filters. Climate risk generally refers to the risk of negative impacts on a company’s business or financial condition due to climate-related conditions around the globe or the transition to a lower carbon economy. The climate risk models used in connection with the Index seek to identify large U.S. companies that are more likely to perform well in future climate scenarios.

The Index is an “excess return” index. The Index’s return reflects the total return on an investment in the underlying component stocks (including reinvestment of all dividends, interest, and other income), less certain negative adjustments and deductions that reduce the performance of the Index.

The sponsor of the Index and the Underlying SGI Index (as defined below) is Société Générale. The index calculator is S&P Opco, LLC (a subsidiary of S&P Dow Jones Indices LLC). The climate risk models used in connection with the Index are produced by Entelligent, Inc. On January 12, 2022, Societe Generale, through an indirect wholly owned subsidiary, acquired a passive ownership interest and a board seat in Entelligent, Inc. Sustainalytics provides the data used to support the ESG exclusion filters. None of these companies are affiliated with Principal.

See APPENDIX A for the applicable index disclosures.

Segment Credits on Segment End Date

Point-to-Point Crediting Method

For each Index-Linked Segment Option, its Segment Term is not only the potential duration of your investment in that Segment Option, but also the length of time that the Segment Option is linked to the performance of its Index.

The Index-Linked Segment Options are linked to the performance of their Indices based on the point-to-point crediting method. Under this approach, the amounts you allocate to one or more Segment Options that are linked to certain Indices will change in values during defined periods of time (i.e., the Segment Term). In other words, a specific Index’s performance rate, whether positive or negative, is generally measured on a point-to-point basis from the Index’s value on the first day of the Segment Term to the Index’s value on the last day of the Segment Term. The Index performance from the Segment Start Date to the Segment End Date is the percentage change in the value of the applicable Index between those dates.

Certain of the following rates will apply to the Index-Linked Segment Options that are currently offered under the Contract:

•Cap Rate - When positive performance is subject to a Cap Rate, the interest credited on the Segment End Date will typically equal the positive change in the Index Value multiplied by the Participation Rate up to the Cap Rate.

•Participation Rate – When positive performance is subject to a Participation Rate, the interest credited on the Segment End Date will typically equal the positive change in the Index Value multiplied by the Participation Rate. If your Contract also has a Cap Rate, please see the bullet point immediately above for information on how the Participation Rate and Cap Rate operate together.

•Buffer Rate – When negative performance is subject to a Buffer Rate, we will absorb any loss up to the maximum Buffer Rate. Any negative Index Value change in excess of the Buffer Rate will be your responsibility.

•Floor Rate - When negative performance is subject to a Floor Rate, we will absorb any loss in excess of the Floor Rate. Any negative Index Value change less than the Floor Rate will be your responsibility.

26

Point-to-Point Crediting Method Examples

For each scenario below, assume a 1-year Segment Term with a 0% Floor Rate, a 5% Cap Rate, and a 75% Participation Rate.

Scenario	Beginning Index Value	Ending Index Value	Index Change	Segment Credit percentage
1	100	125	25%	5%
2	100	105	5%	3.75%
3	100	100	0%	0%
4	100	95	-5%	0%
5	100	85	-15%	0%

For each scenario below, assume a 1-year Segment Term with a 10% Floor Rate, a 15% Cap Rate, and a 100% Participation Rate.

Scenario	Beginning Index Value	Ending Index Value	Index Change	Segment Credit percentage
1	100	125	25%	15%
2	100	105	5%	5%
3	100	100	0%	0%
4	100	95	-5%	-5%
5	100	85	-15%	-10%

For each scenario below, assume a 6-year Segment Term with a 10% Buffer Rate, an uncapped Cap Rate, and a 110% Participation Rate.

Scenario	Beginning Index Value	Ending Index Value	Index Change	Segment Credit percentage
1	100	200	100%	110%
2	100	125	25%	27.5%
3	100	100	0%	0%
4	100	95	-5%	0%
5	100	75	-25%	-15%

Because we only calculate Segment Credits on the Segment End Date, the Segment Credit typically does not reflect the highest or lowest Index Value that occurred during the Segment Term. The Index Change is subject to further adjustment(s) in arriving at a Segment Credit for the Segment Option. The adjustment(s) are based on any Cap Rate, Participation Rate, Buffer Rate or Floor Rate that may apply.

Segment Interim Value

Segment Interim Values only apply on dates other the Segment Start Date and Segment End Date.

The Segment Interim Value is the Crediting Base adjusted for the Equity Adjustment for each Index-Linked Segment Option. The calculation is:

Segment Crediting Base * (1 + Equity Adjustment percentage)

Generally, the Segment Interim Value will tend to reflect less gain and more loss (as applicable) than would apply at the end of a Segment Term. This means that you might not receive the full protection of a Buffer or Floor Rate reflected in your Segment Interim Value. The Segment Interim Value may result in a loss even if the Index Value at the time the Segment Interim Value is calculated is higher than the Index Value on the Segment Start Date.

27

Calculation of Equity Adjustment

The Equity Adjustment is intended to be close to the change in the market value of derivative instruments that hedge risks associated with our obligation to apply Segment Credits to the Index-Linked Segment Options. The Equity Adjustment is the adjustment to the Accumulated Value, expressed as a percentage, based on the change in the value of the hypothetical derivative assets which are designed to replicate credits provided by a Segment Option at the end of a Segment Term. It does not apply to either the Initial Holding Account or the Fixed Segment Option. On the Segment Start Date and Segment End Date, the Equity Adjustment is zero.

The Equity Adjustment is calculated as:

Derivative ValCur – (Derivative ValBeg * [1 – (Time Elapsed / Segment Term)])

Where:

•Derivative ValCur    is the value, calculated using the Black-Scholes formula, of a hypothetical basket of

derivatives associated with the Index-Linked Segment Option on the date the Equity Adjustment is calculated.

•Derivative ValBegis the value, calculated using the Black-Scholes formula, of a hypothetical basket of

derivatives associated with the Index-Linked Segment Option on the Segment Start

Date.

•Time Elapsed        is the number of whole years elapsed between the Segment Start Date and the date

the Equity Adjustment is calculated.

•Segment Term        is the Segment Term.

Parameters (such as interest rates, volatility, and dividends) used in the Black-Scholes formula to calculate the value of derivatives will be consistent with the most recently available market data for such parameters. These parameters are provided by an independent third-party and, if any of these parameters become unavailable for any reason, we will select a new parameter or provider at our sole discretion.

The hypothetical basket of derivatives used in the Equity Adjustment depends on the Segment Option selected and may include:

•Buffer

◦Long ATM Call

◦Short OTM Call

◦Short OTM Put

•Floor

◦Long ATM Call

◦Short OTM Call

◦Short ATM Put

◦Long OTM Put

The duration of each derivative is based on the Segment Term selected. The underlying index of each derivative is based on the Segment Option selected. The moneyness of each derivative depends on the structured payoff of the Segment Option. “Moneyness” is a term used to describe whether a contract is either in the money (ITM), out of the money (OTM) or at the money (ATM). The following is a brief description of ITM, OTM and ATM.

•ITM - An option that is in-the-money, or ITM, has intrinsic value. A call option is ITM if the strike price is below the underlying security’s current trading price.  A put option is ITM if the strike price is above the current price of the underlying security. 

•OTM - An option that is out-of-the-money, or OTM, has no intrinsic value. A call option is OTM if the strike price is above the underlying security’s current trading price.  Put options are OTM if the strike price is lower than the current price of the underlying security.

•ATM - An at-the-money, or ATM, option is a call or a put option that has a strike price about equal to the current price of the underlying security. 

28

Negative Adjustments to Crediting Base

Crediting Base

On the initial Segment Start Date, the Crediting Base for any Segment Option is the amount from the Initial Holding Account that gets allocated to the specific Segment Option.

On any other date, the Crediting Base for any Segment Option is equal to the following for that Segment Option:

Cred BasePrev – Seg Fee + Seg Credit + TransfersIn – TransfersOut – Surrenders

Where:

•Cred BasePrev    is the Segment Crediting Base on the previous day

•Seg Fee    is the Segment Fee amount applied to the Segment Option on this date

•Seg Credit    is the amount of Segment Credits credited to the Segment Option on this date

•TransfersIn    is the amount transferred from other Segment Options to this Segment Option            

on this date

•TransfersOut    is the amount transferred to other Segment Options from this Segment Option             

on this date

•Surrenders    is the Surrender amount deducted from this Segment Option on this date

Segment Fees (arising from the optional Rate Enhancement Rider) and Surrenders may be applied on any day in the Segment Term. Segment Credits and Transfers are only applied at the end of a Segment Term.

Impact of Negative Adjustments

The three areas in which negative adjustments to your Crediting Base will occur are Rate Enhancement Rider fees, Surrenders and negative Segment Credits. The Crediting Base will be reduced daily for the Rate Enhancement Rider fees if that rider is selected. For each Surrender the Crediting Base will be reduced proportionally to the Segment Interim Value immediately preceding the Surrender unless the Surrender is a partial withdrawal satisfying the Required Minimum Distribution requirement for your Contract. If the Surrender is a partial withdrawal satisfying the Required Minimum Distribution requirement for your Contract, the negative adjustment to your Crediting Base will be no greater than the amount of the Segment Interim Value withdrawn. If you receive a negative Segment Credit on the Segment End Date, the Crediting Base will be reduced by the entire amount of the negative Segment Credit.

Negative Adjustments to Crediting Base Examples

For examples of how a withdrawal causes a negative adjustment to the Crediting Base, see 4. FEES AND CHARGES - Deferred Sales Load ("surrender Charge") - Surrender Charge Example.

For an example of how the Rate Enhancement Rider charge causes a negative adjustment to the Crediting Base, see Optional Rate Enhancement Rider below.

Below is an example of how a negative Segment Credit causes a negative adjustment to the Crediting Base. Assume this is a 1-year Segment Option with a Premium Payment of $100,000.00.

Contract Year	Beginning Crediting Base	Segment Credit	Crediting Base After Segment Credit
1	$100,000.00	$5,000.00	$105,000.00
2	$105,000.00	-$15,000.00	$90,000.00
3	$90,000.00	$2,000.00	$92,000.00

2)Portion of Crediting Base Surrendered = $4,500.00 / $87,170.00 * $100,000.00 = $5,162.33

3)Bond Adjustment Amount = $5,162.33 * 2.34% = $120.80

4)Surrender Charge = Max($4,620.80 - $10,000.00, $0.00) * 8.00% = $0.00

5)Total Crediting Base after Withdrawal = $100,000.00 – Min($5,162.33, $4,500.00) = $95,500.00

Optional Rate Enhancement Rider

The Rate Enhancement Rider is an optional benefit that can only be elected at the time the Contract is issued. The Rate Enhancement Rider effective date is the same as the Contract Date unless a different rider effective date is shown on your Contract’s Data Page. The Rate Enhancement Rider is available for all Index-Linked Segment Options.

Rider Benefit

The Rate Enhancement Rider provides an increased Participation Rate and/or Cap Rate on the Index-Linked Segment Options. The increased Participation Rate and/or Cap Rate (as applicable) are shown on your Contract’s Data Page.

The risk in purchasing this rider is that you may not receive additional Segment Credits in excess of the Rate Enhancement Rider fee. For example, one situation where no benefit is provided for a Segment Term would be if the additional positive Segment Credit received is less than the Rate Enhancement Rider fee. Also, if performance of the applicable Segment Option is negative for a Segment Term, you will not receive additional Segment Credits under this rider for that Segment Term.

Rider Charge

The annual charge for the Rate Enhancement Rider is 0.95%, which is deducted daily. If the Rate Enhancement Rider is terminated (as discussed below), the charge for the Rate Enhancement Rider ends.

30

Rider Termination

The Rate Enhancement Rider terminates on the earliest of the following:

1.The Contract is terminated; or

2.A Segment Anniversary divisible by six, in which we receive your request to terminate the Rate Enhancement Rider (for example, if your initial Segment Start Date was 9/1/2022, you could only terminate the Rate Enhancement Rider on 9/1/2028, 9/1/2034, 9/1/2040, etc.).

If the Rate Enhancement Rider terminates for any reason other than your full Surrender of your Contract, the Rate Enhancement Rider may not be reinstated. If you Surrender your Contract with the Rate Enhancement Rider attached and the Contract is later reinstated, the Rate Enhancement Rider also must be reinstated. If the Contract and the Rate Enhancement Rider are reinstated, the Rate Enhancement Rider will be reinstated as of the termination date. At the time the Rate Enhancement Rider is reinstated, we will deduct Rate Enhancement Rider charges scheduled during the period between the termination and reinstatement and make any other adjustments necessary to reflect any change in the amount reinstated and the Contract Accumulated Value as of the date of termination.

Discontinuation or Substitution of an Index

The Indices available on the Contract Date are not guaranteed for the life of the Contract. For any Index-Linked Segment Option, we will substitute an existing Index if the Index is discontinued or when there is a substantial change in the calculation of the Index that materially modifies the performance or values of the Index. We may also substitute an Index should Index Values become unavailable for any reason. The substitution of an Index will have no impact on an Index-Linked Segment Option’s Segment Term, Cap Rate, Participation Rate, Buffer Rate, or Floor Rate, as applicable.

When substituting an Index, we will attempt to select an alternative Index that, in our judgment, has an investment and risk profile similar to the original Index. We will notify you at least 30 days in advance of the substitution, and the notice will include the Index and Segment Option(s) involved. In the event that it is necessary to substitute on less than 30 days’ notice due to circumstances outside of our control, we will provide notice of the substitution as soon as practicable. If required by law, any substitution of an Index is subject to approval by the state insurance authorities where the Contract was issued.

We reserve the right to add and remove Index Segment Options as available investment options. There is no guarantee that any Index-Linked Segment Option will always be available in the future, except we will always offer at least one Index-Linked Segment Option for investment.

If we remove an Index-Linked Segment Option, it will be closed such that no reinvestments or Transfers will be allowed into that Segment Option. If you are currently invested in an Index-Linked Segment Option that is being removed, you may remain in that Segment Option until the end of the Segment Term.

Segment Lock-In Feature

The Contract’s lock-in features allow you to lock in an Index-Linked Segment Option’s Equity Adjustment prior to the Segment End Date. These lock-in features are available with all of the Index-Linked Segment Options under the Contract. There is no additional charge for these lock-in features.

The lock-in features may be of interest to people who:

•Are interested in eliminating some of the uncertainty regarding future Index performance; or

•Are wanting to potentially limit the impact of a negative Segment Credit they may otherwise receive if they don't lock-in.

Upon exercising a lock-in, the Owner will receive a Segment Credit equal to the locked-in Equity Adjustment on the Segment End Date. Between the date of lock-in and the Segment End Date, the Segment Interim Value will be calculated using the locked-in Equity Adjustment. If a lock-in has been exercised and the current Segment End Date is later than the next Segment Anniversary, the Segment End Date is moved up to the next Segment Anniversary. For example, if the Segment Start Date is 9/1/2022 for a 6-year Segment Option (Segment End Date is 9/1/2028 before lock-in) and you exercise a lock-in on 6/22/2025, the Segment End Date will move to 9/1/2025 at the time of exercising the lock-in.

31

There are two ways to exercise a lock-in for an Index-Linked Segment Option: Manual Segment Lock-In and Automatic Segment Lock-In.

Manual Segment Lock-In. Under this method, you exercise a lock-in by submitting a request directing us to lock in the Equity Adjustment for an Index-Linked Segment Option. We will lock in the Equity Adjustment on the Valuation Day we receive your request in Good Order. For example, if you submit a request in Good Order prior to the end of the Valuation Day (generally 4:00 p.m. E.T.) to lock in a Segment Option, the lock-in will be effective on that day (Lock-In Date). If your request is received in Good Order after the end of the Valuation Day (generally 4:00 p.m. E.T.), or on a weekend or on a holiday, the lock-in will be effective on the next Valuation Day (Lock-In Date).

Automatic Segment Lock-In. Under this method, if a lock-in has not yet occurred, you may contact us to set an upper Lock-In Threshold and/or lower Lock-In Threshold. If you set an upper Lock-In Threshold, we will automatically lock in the Equity Adjustment during the remainder of the Segment Term if the Equity Adjustment reaches and/or crosses the upper Lock-In Threshold. Conversely, if you set a lower Lock-In Threshold, we will lock in the Equity Adjustment during the remainder of the Segment Term if the Equity Adjustment reaches and/or crosses the lower Lock-In Threshold. For example, if an upper threshold of 10% is set, the Segment Option will not lock in until the Equity Adjustment is at least 10%. This means the locked in Equity Adjustment will be 10% or greater. If a lower threshold of -5% is set, the Segment Option will not lock in until the Equity Adjustment is less than or equal to -5%. This means the locked in Equity Adjustment will be -5% or lower. Please note, we will not accept a request to establish an upper or lower Lock-In Threshold unless the requested Lock-In Threshold is higher or lower, respectively, than the last-calculated Equity Adjustment. Lock-In Threshold(s) may be removed or changed if you provide us with Notice in Good Order at least two Valuation Days prior to the Segment End Date, provided a lock-in has not yet occurred for the specified Segment Option during the Segment Term.

You can request a Segment Lock-In or set Lock-In Threshold(s) on any Valuation Day up to two Valuation Days prior to the applicable Segment End Date. In order to request a Segment Lock-In or set Lock-In Threshold(s) you must provide us with Notice. If you submit a Segment Lock-In request, the Lock-In Date will be the Valuation Day we receive Notice in Good Order to lock the Segment Option. If you establish a Lock-In Threshold, the Lock-In Date will be the Valuation Day where the Equity Adjustment triggers the threshold you set.

Under either method for exercising a lock-in, you will not know the locked-in Equity Adjustment in advance. If you submit a Segment Lock-In request, the locked-in Equity Adjustment may be lower or higher than the Equity Adjustment that was last calculated before you submitted your request. If you establish Lock-In Thresholds, the locked-in Equity Adjustment will be at least equal to the upper threshold or lower threshold, as applicable. For example, if an upper threshold of 10% is set, the Segment Option will not lock in until the Equity Adjustment is at least 10%. This means the locked in Equity Adjustment will be 10% or greater. If a lower threshold of -5% is set, the Segment Option will not lock in until the Equity Adjustment is less than or equal to -5%. This means the locked in Equity Adjustment will be -5% or lower.

We will not provide advice or notify you regarding whether you should exercise the lock-in features or the optimal time for doing so. We will not warn you if you exercise the lock-in features at a sub-optimal time. We are not responsible for any losses related to your decision whether or not to exercise the lock-in features.

Once a lock-in is executed, it is irrevocable for that Segment Term. A lock-in will not be applied retroactively and can only be exercised for the entire Segment Option. A lock-in may only be exercised once per Segment Term for each Index-Linked Segment Option.

We reserve the right to limit the availability of the lock-in features to only certain Index-Linked Segment Options in the future.

8. OPTIONS AT END OF SEGMENT TERM

At the end of a Segment Term for any Segment Option, the following options are available to you:

•You may reinvest your Accumulated Value allocated to the ended Segment Option in the same Segment Option for another Segment Term if that Segment Option is still available. Please note, the Cap Rate, Participation Rate, or annual interest rate we declare for the new Segment Term may differ (higher or lower) from the previous Segment Term, subject to the guaranteed limits described in this prospectus.

32

•You may Transfer your Accumulated Value allocated to the ended Segment Option to any other Segment Option that is available for investment. Transfers from a Segment Option are only allowed on the Segment End Date. If you wish to Transfer, you must Notify us at least two Valuation Days prior to the Segment End Date.

•You may withdraw or Annuitize your Accumulated Value allocated to the ended Segment Option, subject to the terms and conditions described in this prospectus. Withdrawals and Annuitization are not restricted to Segment End Dates, but amounts withdrawn or Annuitized from a Segment Option on its Segment End Date will not be based on a Segment Interim Value. However, such withdrawals may be subject to surrender charges (surrender charges do not apply upon Annuitization). See 4. FEES AND CHARGES - Deferred Sales Load ("Surrender Charge"). In addition, such withdrawals and Annuitizations will be subject to the Bond Adjustment. See 9. CONTRACT VALUES - Bond Adjustment.

In the absence of instructions, your Accumulated Value in the ended Segment Option will be automatically re-invested in the same Segment Option for another Segment Term, as described above. If we no longer offer the same Segment Option, we will select a new Segment Option from those that we do offer. The Segment Option selected will be one with the same Index with a one-year Segment Term. If there is no such Segment Option, the Accumulated Value for the applicable Segment Option will be allocated to the one-year Fixed Segment Option.

As each Segment Term nears its Segment End Date, we will provide at least fifteen (15) days advance notice of the Segment Options that will be available to you on the Segment End Date, including the Cap Rates, Participation Rates, and annual interest rates we have declared for new Segment Terms. Any or all of these Cap Rates, Participation Rates, and annual interest rates may be different (higher or lower) from the Cap Rates, Participation Rates, and annual interest rates that we declared for previous Segment Terms, subject to the guaranteed limits described in this prospectus. We may offer different rates (higher or lower) to new investors or classes of investors that purchased the Contract at different times.

9. CONTRACT VALUES

Accumulated Value

The Accumulated Value is the sum of the Segment Interim Values, Segment Values, and Fixed Segment Values, as applicable, plus the total value of any allocation to the Initial Holding Account and Fixed Segment Option(s).

Bond Adjustment

The Bond Adjustment is the adjustment based on the change in value of the hypothetical fixed income assets supporting the Contract. The Company invests in fixed income assets to support the value of the Segment Options. The Bond Adjustment is intended to be close to the change in value of the fixed income assets that are sold to cover any distribution from the Contract. It applies to all Segment Options on any full and partial withdrawals, Annuitizations and death benefits (including those taken on a Segment End Date).

The Bond Adjustment is calculated as:

Cred Base * {[(1+ Index ValBeg)/ (1+ Index ValCur)]Time Rem. – 1}

Where:

•Cred Base    is the Crediting Base immediately prior to any Surrender

•Index ValBeg    is the Beginning Bond Adjustment Index Value

•Index ValCuris the Current Bond Adjustment Index Value

•Time Rem    is the number of whole months remaining until the end of the current Bond

Adjustment Period, divided by 12.

The Bond Adjustment Index is the 6 Year Point on the A Rated US Bloomberg Fair Value Curve. If this Index becomes unavailable for the Company to utilize or the calculation of the values substantially changes, the Company may choose another Bond Adjustment Index and you will be made aware of the change. The initial Beginning Bond Adjustment Index Value is equal to the closing price of this Index on the Contract Date. Each Beginning Bond Adjustment Index Value after the initial one is equal to the closing price of this Index on the Segment Anniversary divisible by six (i.e., 6, 12, 18, etc.). The Current Bond Adjustment Index Value is equal to the most recent closing

33

price of this Index on the day the adjustment is calculated. The first Bond Adjustment period begins on the first Segment Start Date, and it restarts on each Segment Anniversary divisible by six.

The risk with the Bond Adjustment is that you could receive a lower amount on withdrawals, Annuitization or death benefits because the Bond Adjustment could be negative based on interest rate movements.

10. WITHDRAWALS

This section describes full and partial withdrawals under your Contract. For information about the risks in taking withdrawals, see 2. RISK FACTORS - Liquidity Risk -Consequences of Withdrawals/Surrenders Generally.

Withdrawals Generally

You may make full or partial withdrawals under this Contract at any time prior to the Annuitization Date provided the Owner and Joint Owner, if any, are living and provided that you give us Notice in Good Order at our Home Office. Withdrawal requests may be sent to us at:

Principal Life Insurance Company

PO Box 9382

Des Moines, Iowa 50306-9382

When you request a withdrawal, the amount provided to you is the Surrender Value, which includes the Segment Interim Value if the withdrawal is not on a Segment Start Date or Segment End Date of the Segment Option being withdrawn from. In arriving at the Surrender Value, we will apply a Bond Adjustment to the Accumulated Value and subtract any applicable Surrender Charge and other applicalbe fees (see 4. FEES AND CHARGES, and 9. CONTRACT VALUES - Bond Adjustment). Full and partial withdrawals may be subject to taxes and to a separate 10% federal tax penalty if made before the Owner is 59½ years old (see 14. TAXES).

Withdrawals are generally paid within seven days of the effective date of the request for Surrender (or earlier if required by law). However, certain delays in payment are permitted (see 15. ADDITIONAL INFORMATION ABOUT THE CONTRACT – Delay of Payments and Other Transactions).

Full Withdrawal

You may take a full withdrawal under this Contract for the Surrender Value. The following provisions apply to full withdrawals:

•You may take the withdrawal under the Contract at any time before the Annuitization Date.

•The Surrender Value at any time is the Accumulated Value (on the date we receive your Notice in Good Order) adjusted for the Bond Adjustment, less any applicable Surrender Charge and other fees and charges.

•We reserve the right to require you to return the Contract.

•The written consent of all collateral assignees and irrevocable beneficiaries must be obtained prior to a full withdrawal. A collateral assignment is an agreement under which you assign the annuity benefits to a lender as collateral for a loan. An irrevocable beneficiary is someone whose name cannot be removed from this annuity Contract without his or her consent.

For additional information on the risks involved in taking a full withdrawal, see 2. RISK FACTORS - Liquidity Risk.

Partial Withdrawals

You may take unscheduled and scheduled partial withdrawals from this Contract by providing us Notice. Partial withdrawals reduce the Accumulated Value and Crediting Base of the Contract and are deducted proportionately from the Segment Options unless you direct otherwise. The deductions are based on the values as of the end of day of the effective date of the withdrawal.

Unscheduled Partial Withdrawal

•You may withdraw a part of your Accumulated Value at any time before the Annuitization Date.

•You must specify the dollar amount of the withdrawal (which must be at least $100).

•If you specify withdrawal allocation percentages as part of a partial withdrawal request, the withdrawal is deducted from the Segment Options according to the withdrawal allocation percentages you provide to us.

34

•If you do not provide us with specific withdrawal allocation percentages, the withdrawal is deducted in the same proportion as the Accumulated Value is spread throughout the Segment Options at that point in time.

•Your Accumulated Value after the unscheduled partial withdrawal must be equal to or greater than $5,000; we reserve the right to increase this amount up to and including $10,000. If your Accumulated Value is less than the minimum threshold, we will treat the request as a request for a full withdrawal.

•The written consent of all collateral assignees and irrevocable beneficiaries must be obtained prior to withdrawal.

For additional information on the risks involved in taking an unscheduled partial withdrawal, see 2. RISK FACTORS - Liquidity Risk.

Scheduled Partial Withdrawal

•You may request partial withdrawals from any of the Segment Options (to which you are allocated) on a scheduled basis.

•Your Accumulated Value must be at least $5,000 when the scheduled partial withdrawals begin.

•You may specify monthly, quarterly, semi-annually or annually and choose a withdrawal date (other than the 29th, 30th or 31st of any month).

•If the selected date is not a Valuation Date, the partial withdrawal is completed on the next Valuation Date.

•We take amounts from your Segment Option(s) to equal, in total, the dollar amount of the partial withdrawal request plus or minus the Bond Adjustment (as applicable) and plus any applicable Surrender Charge.

•Scheduled partial withdrawals will end on the earliest of:

othe date we receive Notice in Good Order to end the payments;

othe date you take a full withdrawal from the Contract;

othe date all or a portion of the Accumulated Value is applied to an annuity benefit payment option;

othe date the death benefit is distributed;

othe Annuitization Date; and

othe Accumulated Value is zero.

•For additional information on the risks involved in taking a scheduled partial withdrawal, see 2. RISK FACTORS - Liquidity Risk.

•The written consent of all collateral assignees and irrevocable beneficiaries must be obtained prior to a partial withdrawal.

11. DEATH BENEFIT

General Death Benefit Provisions

If the Owner or any Joint Owner dies prior to the Annuitization Date, we will pay the death benefit upon our receipt of required documents and Notice, in Good Order, including due proof of death. Proof of death includes a copy of a death certificate, a certified copy of a court order, a written statement by a medical doctor, or other proof satisfactory to us.

The Accumulated Value will remain invested in the Segment Options until the Valuation Day on which we receive the required documents in Good Order. If more than one beneficiary is named, each beneficiary's portion of the death benefit will remain invested in the Segment Options until the Valuation Day on which we receive the required documents for that beneficiary. The death benefit is subject to the Segment Interim Value and Bond Adjustment, which factors in market performance. See 2. RISK FACTORS - Segment Interim Value and 9. CONTRACT VALUES - Bond Adjustment.

We will pay interest on the death benefit from the first day the Accumulated Value is no longer invested in the Segment Options until payment is made. We will determine the rate of interest, which will not be less than the interest rate required by the applicable state's law.

35

If the Owner or any Joint Owner dies prior to the Annuitization Date, the death benefit may be distributed in a lump sum or within five years of the date of death or distributed over a time period not extending beyond the life expectancy of the beneficiary as provided for in Internal Revenue Code (“IRC”) section 72(s), as may be amended from time to time. If payments are made over the life expectancy of the beneficiary, they must begin not later than one year after the date of death of the Owner or Joint Owner.

If the Owner or Joint Owner dies on or after the Annuitization Date and before the entire interest in this Contract has been distributed, the remaining portion of such interest will be distributed at least as rapidly as required under applicable federal tax laws, including, particularly, IRC section 72(s), as may be amended from time to time.

Notwithstanding any provision to the contrary in this Contract, any payment of death benefits must comply with all applicable laws, including IRC section 72(s), as may be amended from time to time.

Death of Owner(s)

The following provisions apply upon an Owner’s death if a Contract is not jointly owned:

1. If the surviving spouse is the only primary beneficiary, the surviving spouse may elect to become the Owner and continue the Contract or elect to receive the death benefit.

2. If the primary beneficiary is not the surviving spouse, the primary beneficiary will receive the death benefit.

The following provisions apply upon the death of the first Joint Owner to die when a Contract is jointly owned:

1. The surviving Joint Owner will be treated as the primary beneficiary. Any other beneficiary designation on record will be treated as contingent beneficiary.

2. If the surviving Joint Owner is the spouse of the deceased Joint Owner, the surviving spouse may elect to become the Owner and continue the Contract or elect to receive the death benefit.

Death of Annuitant(s)

If an Annuitant who is not an Owner dies while this Contract is in force, a new Annuitant may be named unless the Owner is a corporation, trust, or other entity.

If the Owner is a corporation, trust or other entity, the death benefit will be payable upon the death of the Annuitant, or, in the case of Joint Annuitants, upon the death of the first Joint Annuitant to die.

Death Benefit

If the age of the oldest Owner on the date the application is signed is 79 or younger, the death benefit is equal to the greater of 1 or 2 where:

1. Is the Accumulated Value, subject to the Bond Adjustment, on the date we receive the proof of death and all required documents in Good Order; and

2. Is the Total Premium Payment minus an adjustment (as described below) for each partial withdrawal (and any applicable Surrender Charge and fees) and an adjustment for each partial Annuitization made prior to the date we receive the poof of death and all required documents.

Death Benefit Example 1

Contract Issue date = August 31

Total Premium Payment = $100,000

On November 3 of the same calendar year, assume the Accumulated Value is $101,000 and the Bond Adjustment is -$3,000.

The Death Benefit on November 3 is the greatest of 1 or 2 below assuming the age of the oldest Owner on the date the application was signed was 79 or younger:

1.$98,000 = $101,000 - $3,000

2.$100,000 = Total Premium Payment

The Death Benefit on November 3 is $100,000.

36

Death Benefit Example 2

Contract Issue date = August 31

Total Premium Payment = $100,000

On November 3 of the same calendar year, assume the Accumulated Value is $99,000 and the Bond Adjustment is $2,000.

The Death Benefit on November 3 is the greatest of 1 or 2 below assuming the age of the oldest Owner on the date the application was signed was 79 or younger:

1.$101,000 = $99,000 + $2,000

2.$100,000 = Total Premium Payment

The Death Benefit on November 3 is $101,000.

Death Benefit Example 3

Contract Issue date = August 31

Total Premium Payment = $100,000

On November 3 of the same calendar year, assume the Accumulated Value is $90,000 and the Bond Adjustment is -$4,000.

The Death Benefit on November 3 is the greatest of 1 or 2 below assuming the age of the oldest Owner on the date the application was signed was 79 or younger:

1.$86,000 = $90,000 - $4,000

2.$100,000 = Total Premium Payment

The Death Benefit on November 3 is $100,000.

The adjustment for each partial Surrender (and any applicable Surrender Charges and fees) and for each partial Annuitization will reduce the death benefit in the same proportion that the Accumulated Value was reduced on the date of the partial Surrender or partial Annuitization. The adjustment for partial Surrenders is equal to (1 divided by 2) multiplied by 3, where:

1. Is the amount of the partial Surrender (and any applicable Surrender Charges and fees) or the amount of the partial Annuitization; and

2. Is the Accumulated Value immediately prior to the partial Surrender or partial Annuitization; and

3. Is the Total Premium Payment adjusted for prior partial Surrenders and partial Annuitizations immediately prior to the current partial Surrender or partial Annuitization.

Example of Adjustment to Total Premium Payment for a Partial Surrender or Partial Annuitization

Contract Issue date = August 31

Total Premium Payment = $100,000

On November 3 of the same calendar year, assume the Accumulated Value is $90,000 and the Bond Adjustment is -$4,000 and a partial withdrawal of $5,000

The Death Benefit on November 3 is the greatest of 1 or 2 below assuming the age of the oldest Owner on the date the application was signed was 79 or younger:

1.$81,000 = ($90,000 - $5,000) - $4,000

2.$94,444.44 = Total Premium Payment adjusted for the partial withdrawal = (1 - $5,000/$90,000) * $100,000

The Death Benefit on November 3 is $94,444.44.

If the age of the oldest Owner on the date the application is signed is 80 or older, the death benefit is equal to the Accumulated Value, subject to the Bond Adjustment, on the date we receive the proof of death and all required documents in Good Order.

37

Death Benefit Example 4 (no withdrawals)

Contract Issue date = August 31

Total Premium Payment = $100,000

On November 3 of the same calendar year, assume the Accumulated Value is $101,000 and the Bond Adjustment is -$3,000.

The Death Benefit on November 3 is the Accumulated Value adjusted for the Bond Adjustment assuming the age of the oldest Owner on the date the application was signed was 80 or older.

The Death Benefit on November 3 is $98,000 = $101,000 - $3,000.

Death Benefit Example 5 (no withdrawals)

Contract Issue date = August 31

Total Premium Payment = $100,000

On November 3 of the same calendar year, assume the Accumulated Value is $99,000 and the Bond Adjustment is $2,000.

The Death Benefit on November 3 is the Accumulated Value adjusted for the Bond Adjustment assuming the age of the oldest Owner on the date the application was signed was 80 or older.

The Death Benefit on November 3 is $101,000 = $99,000 + $2,000.

12. STATEMENTS

We will mail to you a statement, along with any reports required by state law, of your current Accumulated Value at least once per year prior to the Annuitization Date. After the Annuitization Date, any reports will be mailed to the person receiving the annuity benefit payments.

13. ANNUITIZATION

Annuitization Date

You may specify an Annuitization Date in your application. If you do not specify an Annuitization Date, the Annuitization Date is the Maximum Annuitization Date shown on the Data Page. You may change the Annuitization Date with our prior approval. The request must be in writing. You may not select an Annuitization Date that falls prior to the second Contract Anniversary or after the Maximum Annuitization Date. Generally, the Maximum Annuitization Date is the Contract Anniversary following the Annuitant’s attainment of age 95. The Maximum Annuitization Date can be found on the Data Page. Annuitizations are subject to the Segment Interim Value and Bond Adjustment, which factors in market performance. See 2. RISK FACTORS – Segment Interim Value and 9. CONTRACT VALUES - Bond Adjustment.

If Joint Annuitants are named in the application, the Maximum Annuitization Date will be set based on the age of the older Joint Annuitant.

Full Annuitization

Any time after the second Contract Year, you may Annuitize your Contract by electing to receive payments under an annuity benefit payment option. If the Accumulated Value on the Annuitization Date is less than $2,000, we may pay out the entire amount in a single payment. The Contract would then be canceled. You may select when you want the payments to begin (within the period that begins the Valuation Day following our receipt of your instruction and ends one year after our receipt of your instructions).

Once payments begin under the annuity benefit payment option you choose, the option may not be changed. In addition, once payments begin, you may not surrender, withdraw or otherwise liquidate or commute any of the portion of your Accumulated Value that has been Annuitized.

Depending on the type of annuity benefit payment option selected, payments that are initiated either before or after the Annuitization Date may be subject to penalty taxes (see 14. TAXES). You should consider this carefully when you select or change the annuity benefit payment commencement date.

38

Partial Annuitization

You have the right to Annuitize a portion of your Accumulated Value.After the second Contract Year and prior to the Annuitization Date, you may Annuitize a portion of your Accumulated Value by sending us a Notice in Good Order.

The minimum partial Annuitization amount is $2,000. Any partial Annuitization request that reduces the Accumulated Value to less than $5,000 will be treated as a request for full Annuitization.

Annuity Benefit Payment Options

You may select one of the annuity benefit payment options listed below. Once payments begin under the option you select, the option may not be changed. In addition, once payments begin you may not surrender or otherwise liquidate or commute any portion of your Accumulated Value that has been Annuitized.

We offer fixed annuity benefit payments only. No surrender charge is imposed on any portion of your Accumulated Value that has been Annuitized.

You may choose from several fixed annuity benefit payment options. Payments will be made on the frequency you choose. You may elect to have your annuity benefit payments made on a monthly, quarterly, semiannual or annual basis. The dollar amount of the payments is specified for the entire payment period according to the option selected. There is no right to take any full or partial withdrawals after the Annuitization Date. The fixed annuity benefit payment must begin within one year of the annuity benefit election.

The amount of the fixed annuity benefit payment depends on the:

•amount of Accumulated Value (adjusted by the Bond Adjustment) applied to the annuity benefit payment option;

•annuity benefit payment option selected;

•age and gender of the Annuitant (unless fixed period income option is selected);

•frequency of the annuity benefit payments; and

•duration of the annuity benefit payments.

The amount of the initial payment is determined by applying all or a portion of the Accumulated Value, plus or minus the Bond Adjustment (as applicable), less any applicable premium tax and other expenses, as of the date of the application to the annuity table for the Annuitant’s annuity benefit payment option, gender, and age. Minimum annuity benefit payment amounts will be based on the Annuity 2012 Individual Annuity Mortality Period Life Table as stated in the Contract. This basis is guaranteed for the life of the Contract for the following fixed annuity benefit payment options: Life Income, Life Income with Period Certain, Joint and Survivor Life Income, and Joint and Survivor Life Income Period Certain. With our written approval, other annuity benefit payment options may be available without this guaranteed basis.

Annuity benefit payments generally are higher for male annuitants than for female annuitants with an otherwise identical Contract. This is because statistically females have longer life expectancies than males. In certain states, this difference may not be taken into consideration in determining the payment amount. Additionally, Contracts with no gender distinctions are made available for certain employer-sponsored plans because, under most such plans, gender discrimination is prohibited by law.

The frequency and duration of the annuity benefit payments affect the income amount received. The annuity benefit payments generally are lower if you receive payments more frequently. For example, monthly payments generally will be lower than quarterly payments. Generally, all other factors being equal, the longer the duration of annuity benefit payments, the lower the annuity benefit payment amounts and the shorter the duration, the higher the annuity benefit payment amounts.

You may select an annuity benefit payment option by written request only. Your selection of an annuity benefit payment option for a partial Annuitization must be in writing and may not be changed after payments begin. Your selection of an annuity benefit payment option for any portion not previously Annuitized may be changed by written request prior to the Annuitization Date.

If an annuity benefit payment option is not selected, we will automatically apply:

•for Contracts with one Annuitant - Life Income with payments guaranteed for a period of 10 years.

39

•for Contracts with Joint Annuitants - Joint and Full Survivor Life Income with payments guaranteed for a period of 10 years.

The available annuity benefit payment options for both full and partial Annuitizations include:

•Life Income - Level payments continue for the Annuitant’s lifetime. If you defer the first payment date, it is possible that you will receive no payments if the Annuitant dies before the first payment date. NOTE: There is no death benefit value remaining and there are no further payments when the Annuitant dies.

•Life Income with Period Certain - Level payments continue during the Annuitant’s lifetime with a guaranteed payment period of 5 to 30 years. If the Annuitant dies before all of the guaranteed payments have been made, the guaranteed payments continue to you or the person(s) you designate until the end of the guaranteed payment period. If a shorter period is required by law, we will pay a commuted value at the end of that shorter period.

•Joint and Survivor- Payments continue as long as either the Annuitant or the Joint Annuitant is alive. You may also choose an option that lowers the amount of income after the death of a Joint Annuitant. It is possible that you will only receive one payment under this option if both Annuitants die before the second payment is due. If you defer the first payment date, it is possible that you will receive no payments if both Annuitants die before the first payment date. NOTE: There is no death benefit value remaining and there are no further payments after both Annuitants die.

•Joint and Survivor with Period Certain - Payments continue as long as either the Annuitant or the Joint Annuitant is alive with a guaranteed payment period of 5 to 30 years. You may choose an option that lowers the amount of income after the death of a Joint Annuitant. If both Annuitants die before all guaranteed payments have been made, the guaranteed payments continue to you or the person(s) you designate until the end of the guaranteed payment period. If a shorter period is required by law, we will pay a commuted value at the end of that shorter period.

With our written approval, other annuity benefit payment options may be available without the minimum annuity benefit payment amount guarantees described in the Contract. These options may include:

•Fixed Period Income - Level payments continue for a fixed period. You may select a range from 5 to 30 years (state variations may apply). If the Annuitant dies before the selected period expires, payments continue to you or the person(s) you designate until the end of the fixed period. Payments stop after all guaranteed payments are received. If a shorter period is required by law, we will pay a commuted value at the end of that shorter period.

•Life with Cash Refund- Level payments continue for the Annuitant’s lifetime. If the Annuitant dies and the total of all payments received is less than the amount of the Accumulated Value applied, the balance is paid to you or the person(s) you designate.

•Life with Installment Refund- Level payments continue for the Annuitant’s lifetime. If the Annuitant dies and the total of all payments received is less than the amount of the Accumulated Value applied, payments continue to you or the person(s) you designate until they equal the amount of the Accumulated Value applied. If the period required to make these payments is longer than allowed by law, we will pay a commuted value at the end of that shorter period.

Tax Considerations Regarding Annuity Benefit Payment Options

If you own one or more tax qualified annuity contracts, you may avoid tax penalties if payments from at least one of your tax qualified contracts begin no later than April 1 following the calendar year in which you turn age 72. The required minimum distribution payment must be in equal (or substantially equal) amounts over your life or over the joint lives of you and your designated beneficiary. These required minimum distribution payments must be made at least once a year. Tax penalties may apply at your death on certain excess accumulations. You should confer with your tax advisor about any potential tax penalties before you select an annuity benefit payment option or take other distributions from the Contract. Additional rules apply to distributions under Non-qualified Contracts (see 14. TAXES).

40

Death of Annuitant (During the Annuitization Period)

If the Annuitant dies during the annuity benefit payment period, remaining payments are made to the Owner throughout the guaranteed payment period, if any, or for the life of any Joint Annuitant, if any. If the Owner is the Annuitant, remaining payments are made to the Joint Owner, if any, or the named beneficiaries. In all cases the person entitled to receive payments also receives any rights and privileges under the annuity benefit payment option.

14. TAXES

The following description is a general summary of the tax rules, primarily related to federal income taxes, which in our opinion are currently in effect. These rules are based on laws, regulations and interpretations which are subject to change at any time. This summary is not comprehensive and is not intended as tax advice. Federal estate and gift tax considerations, as well as state and local taxes, may also be material. You should consult a tax advisor about the tax implications of taking action under a Contract or related retirement plan.

Taxation of Non-Qualified Contracts

Non-Qualified Contracts

Section 72 of the Internal Revenue Code (Code) governs the income taxation of annuities in general.

•Premium Payment made under Non-qualified Contracts are not excludable or deductible from your gross income or any other person’s gross income.

•An increase in the Accumulated Value of a Non-qualified Contract owned by a natural person is generally not taxable until paid out as Surrender proceeds, death benefit proceeds, or otherwise.

•Generally, owners who are non-natural persons (such as a trust, partnership or corporation) are immediately taxed on any increase in the Accumulated Value unless the non-natural person is acting as an agent for a natural person.

The following discussion applies generally to Contracts owned by natural persons.

•Full or partial withdrawals are taxed as ordinary income to the extent of the accumulated income or gain under the Contract.

•The value of the Contract pledged or assigned is taxed as ordinary income to the same extent as a partial Surrender.

•Annuity benefit payments:

◦The basic rule for taxing annuity benefit payments is that part of each annuity benefit payment is considered a nontaxable return of the investment in the Contract and part is considered taxable income. An “exclusion ratio” is applied to each annuity benefit payment to determine how much of the payment is excludable from gross income. The remainder of the annuity benefit payment is includable in gross income for the year received.

◦The “investment in the Contract” is generally the total of the premium payments made less any tax-free return of premiums.

◦After the investment in the Contract is paid out, the full amount of any annuity benefit payment is taxable.

For purposes of determining the amount of taxable income resulting from distributions, all Contracts and other annuity contracts issued by us or our affiliates to the same owner within the same calendar year are treated as if they are a single contract.

Transfer of ownership may have tax consequences to the Owner. For Owners who are non-natural persons changing the Annuitant may have tax consequences to the Owner. Please consult with your tax advisor before changing the Owner or Annuitant on your Contract.

41

Required Distributions for Non-Qualified Contracts

In order for a Non-qualified Contract to be treated as an annuity contract for federal income tax purposes, the Code requires:

•If the person receiving payments dies on or after the Annuitization Date but prior to the time the entire interest in the Contract has been distributed, the remaining portion of the interest is distributed at least as rapidly as under the method of distribution being used as of the date of that person’s death.

•If you die prior to the Annuitization Date, the entire interest in the Contract will be distributed:

◦within five years after the date of your death; or

◦as annuity benefit payments (or similar periodic payments) which begin within one year of your death and which are made over the life of your designated beneficiary or over a period not extending beyond the life expectancy of that beneficiary.

•    If the Contract is owned by a trust, corporation or other non-natural person, then the death of the Annuitant will be treated as the death of the Owner.

Generally, unless the beneficiary elects otherwise, the above requirements are satisfied prior to the Annuitization Date by paying the death benefit in a single payment, subject to proof of your death. The beneficiary may elect, by written request, to receive an annuity benefit payment option instead of a single payment.

If your designated beneficiary is your surviving spouse, the Contract may be continued with your spouse deemed to be the new Owner for purposes of the Code. When the Owner receiving payments is not a natural person, the required distributions provided for in the Code apply upon the death of the Annuitant.

Early Distribution Penalty

If you take a premature distribution from the Contract, you may incur a 10% income tax penalty on the taxable portion of the distribution, unless the distribution is:

•made on or after you reach age 59½;

•made to a beneficiary on or after your death;

•made upon your disability as defined in the Internal Revenue Code;

•part of a series of substantially equal periodic payments for the life or life expectancy of you or you and your designated beneficiary;

•made under an immediate annuity contract; or

•allocable to contributions made prior to August 14, 1982.

Tax reporting distributions from an annuity contract that is owned by a trust: The Internal Revenue Service (IRS) determined in Private Letter Ruling 202031008 that a non-grantor trust cannot attain age 59 ½, become disabled, or have a life expectancy. Thus, the IRS held that those three exceptions to the 10% penalty are not applicable to distributions from a deferred annuity contract that is owned by a non-grantor trust. Alternatively, the IRS held that a deferred annuity contract owned by a grantor trust can utilize those three exceptions if the grantor qualifies for the exception (for example, the grantor attained age 59 ½ at the time of the distribution). Consult a tax advisor for further information.

Tax-Free Exchanges

Under Section 1035 of the Code, the exchange of one annuity contract for another is not a taxable transaction if the same owner is on each contract in the exchange, but may be reportable to the IRS.

Net Investment Income Tax

The Net Investment Income Tax is imposed at a rate of 3.8% on net investment income for higher tax bracket individuals.

This tax may apply to an individual’s net investment income if the individual’s modified Adjustable Gross Income exceeds $200,000 for a single filer or $250,000 for a married filing jointly filer. The tax applies to income from

42

interest, dividends, annuities, royalties and rents not obtained in a normal trade of business. The tax may also apply to certain trusts and estates with net investment income.

Income from annuities that are part of a qualified retirement plan (as described in the following section) are not treated as investment income for the purpose of this new tax and thus are not subject to the new 3.8% rate but may be includible for purposes of determining whether the applicable Net Investment Income Tax income limits are exceeded.

Taxation of Qualified Contracts

Tax-Qualified Contracts: IRA, SEP, and SIMPLE-IRA

The Contract may be used to fund IRAs, SEPs, and SIMPLE-IRAs.

•IRA – An Individual Retirement Annuity (IRA) is a retirement savings annuity. Contributions grow tax deferred.

•SEP-IRA – SEP stands for Simplified Employee Pension and is a form of IRA. A SEP allows you, as an employer, to provide retirement benefits for your employees by contributing to their IRAs.

•SIMPLE-IRA – SIMPLE stands for Savings Incentive Match Plan for Employees. A SIMPLE-IRA allows employees to save for retirement by deferring salary on a pre-tax basis and receiving predetermined company contributions.

The tax rules applicable to owners, annuitants and other payees vary according to the type of plan and the terms and conditions of the plan itself. In general, premium payments made under a retirement program recognized under the Code are excluded from the participant’s gross income for tax purposes prior to the annuity benefit payment date (subject to applicable state law). The portion, if any, of any premium payment made that is not excluded from their gross income is their investment in the Contract. Aggregate deferrals under all plans at the employee’s option may be subject to limitations.

Tax-qualified retirement arrangements, such as IRAs, SEPs, and SIMPLE-IRAs, are tax-deferred. You derive no additional benefit from the tax deferral feature of the annuity. Consequently, an annuity should be used to fund an IRA, or other tax qualified retirement arrangement to benefit from the annuity’s features other than tax deferral. These features may include guaranteed lifetime income, death benefits without Surrender Charges, guaranteed caps on fees, and the ability to Transfer among investment options without sales or withdrawal charges.Check with your tax advisor for the rules which apply to your specific situation.

Premature Distributions

There is a 10% additional penalty tax under the Code on the taxable portion of a “premature distribution” from IRAs, IRA rollovers, SEP-IRAs and SIMPLE-IRAs. The tax penalty is increased to 25% in the case of distributions from SIMPLE-IRAs during the first two years of participation in the SIMPLE IRA. Generally, an amount is a “premature distribution” unless the distribution is:

•made on or after you reach age 59½;

•made to a beneficiary on or after your death;

•made upon your disability as defined in the Internal Revenue Code;

•part of a series of substantially equal periodic payments for the life or life expectancy of you or you and your designated beneficiary;

•made to pay certain deductible medical expenses;

•for health insurance premiums while unemployed;

•for first home purchases (up to $10,000);

•for qualified higher education expenses;

•for qualified disaster tax relief distributions;

•for qualified reservist distributions;

•for amounts levied by the IRS directly against your IRA; or

•a qualified birth or adoption distribution (up to $5,000).

For more information regarding premature distributions, please reference IRS Publication 590-B and consult your tax advisor.

43

Rollover IRAs

If you receive a lump-sum distribution from a qualified retirement plan, tax-sheltered annuity or governmental 457(b) plan, you may maintain the tax-deferred status of the distribution by rolling it over into an eligible retirement plan or IRA. You can accomplish this by electing a direct rollover from the plan, or you can receive the distribution and roll it over into an eligible retirement plan or IRA within 60 days. However, if you do not elect a direct rollover from the plan, the plan is required to withhold 20% of the taxable portion of the distribution. This amount is sent to the IRS as income tax withholding to be credited against your taxes. Amounts received prior to age 59½ and not rolled over may be subject to an additional 10% penalty tax. You may roll over amounts from a Qualified Plan directly to a Roth IRA. As part of this rollover, previously taxed deferred funds from the Qualified Plan are converted to after-tax funds under a Roth IRA. Generally, the entire rollover is taxable (unless it includes after-tax dollars) and is included in gross income in the year of the rollover/conversion. For more information, please consult your tax advisor.

In addition, not more frequently than once every twelve months, an Owner may execute one tax-free indirect rollover from one IRA to another, subject to the 60-day limitation. The once-per-year limitation on rollovers does not apply to direct transfers of funds between IRA providers or to Roth IRA conversions. For more information, please consult your tax advisor.

Roth IRAs

The Contract may be purchased to fund a Roth IRA. Contributions to a Roth IRA are not deductible from taxable income. Subject to certain limitations, a traditional IRA, SEP-IRA or SIMPLE-IRA may be converted into a Roth IRA or a distribution from such an arrangement may be rolled over to a Roth IRA. However, a conversion or a rollover to a Roth IRA is not excludable from gross income. If certain conditions are met, qualified distributions from a Roth IRA are tax-free. For more information, please contact your tax advisor.

Required Minimum Distributions for IRAs

The Required Minimum Distribution (RMD) regulations dictate when individuals must start taking payments from their IRA. Generally speaking, RMDs for IRAs must begin no later than April 1 following the close of the calendar year in which you turn 72. Thereafter, the RMD is required no later than December 31 of each calendar year.

The RMD rules apply to traditional IRAs, as well as SEP-IRAs and SIMPLE-IRAs, during the lifetime and after the death of IRA owners. They do not, however, apply to Roth IRAs during the lifetime of the Roth IRA Owner. If an individual owns more than one IRA, the RMD amount must be determined for each, but the actual distribution can be satisfied from a combination of one or more of the owner's IRAs. Roth IRAs may not be aggregated with other IRAs, but may be aggregated with other Roth IRAs.

NOTE:    Contractual limitations exist that may limit the ability to satisfy an individual's multiple RMD obligations via this annuity.

Failure to comply with the RMD rules can result in tax penalty of 50% on the amount by which the RMD in any year exceeds the amount actually distributed in that year.

Withholding

Annuity benefit payments and other amounts received under the Contract are subject to income tax withholding unless the recipient elects not to have taxes withheld. The amounts withheld vary among recipients depending on the tax status of the individual and the type of payments from which taxes are withheld.

Notwithstanding the recipient’s election, withholding may be required on payments delivered outside the United States. Moreover, special withholding rules may require us to disregard the recipient’s election if the recipient fails to supply us with a taxpayer identification number (social security number for individuals), or if the Internal Revenue Service notifies us that the taxpayer identification number provided by the recipient is incorrect.

15.     ADDITIONAL INFORMATION ABOUT THE CONTRACT

The Contract

The entire Contract is made up of the Contract, amendments, riders and endorsements and Data Page. Only our corporate officers can agree to change or waive any provisions of a Contract. Any change or waiver must be in writing and signed by an officer of the Company.

Reliance on Rule 12h-7

The Company relies on the exemption provided by Rule 12h-7 under the Securities Exchange Act of 1934 from the requirement to file reports pursuant to Section 15(d) of that Act.

The Separate Account

Most assets supporting the Contract are held in an insulated, non-unitized separate account established under Iowa law. These assets are not subject to the claims of the creditors of Principal Life Insurance Company. Any guarantees provided under the Contract are subject to the claims paying ability of Principal Life Insurance Company.

An Owner does not have any interest in or claim on the assets in the Separate Account. In addition, neither an Owner nor amounts allocated to the Segment Options participate in the performance of the assets held in the Separate Account. We are not obligated to invest assets in the Separate Account according to specific guidelines or strategies except as may be required by Iowa or other state insurance laws.

The Separate Account is not registered under the Investment Company Act of 1940.

The General Account

Our general obligations and any guaranteed benefits under this Contract are supported by our General Account and are subject to Principal Life Insurance Company’s claims paying ability. In the Annuitization phase, assets supporting annuity payments are held in the General Account. Assets in the General Account are not segregated for the exclusive benefit of any particular contract or obligation. General Account assets are also available to our general creditors and for conducting routine business activities, such as the payment of salaries, rent and other ordinary business expenses. The General Account is subject to regulation and supervision by the Iowa Insurance Division and to the insurance laws and regulations of all jurisdictions where we are authorized to do business.

Delay of Payments and Other Transactions

In general, we make payment of any amount due under the Contract within seven (7) days from the date we receive a request for payment in Good Order (or earlier if required by law). We generally process other transaction requests as of the close of the Valuation Day on which we receive them in Good Order. We reserve the right to delay payments for up to six months, as permitted by state law.

We also reserve the right to suspend or delay payment or processing of transactions under the following circumstances:

(i) the NYSE is closed (other than customary weekend and holiday closings);

(ii) trading on the NYSE is restricted;

(iii) an emergency exists such that we cannot calculate the Accumulated Value; or

(iv) during any other period when a regulator by order, so permits.

In addition, we reserve the right to defer payment of that portion of your Accumulated Value that is attributable to a Premium Payment made by check for a reasonable period of time (not to exceed 15 business days) to allow the check to clear the banking system.

Setting Cap Rates, Participation Rates and Annual Interest Rates

The Company retains the right to change the Cap Rate, Participation Rate, and Annual Interest Rate for each applicable Segment Option for each new Segment Term at its discretion, subject to the minimum Cap Rate, minimum Participation Rate, and minimum crediting rate for each applicable Segment Option. The Company considers a number of factors when determining whether to make these changes.

We manage the market risk associated with our obligation to provide Segment Credits for Index-Linked
Segment Options in part by trading call and put options and other derivative instruments on the available indices.

45

The costs of the call and put options and other derivative instruments vary based on market conditions, and we may adjust future Cap Rates and Participation Rates based on these changes. You bear the risk that we may reduce the Cap Rates and Participation Rates for future Segment Terms, which will reduce the amount of positive Segment Credit that you may receive. We determine the applicable Cap Rate and Participation Rate for each Segment Option at our sole discretion. Rates offered on Segment Option renewals may be different from those offered to new investors or offered to you at Contract issuance.

We also consider various factors in determining the Buffer Rates and Floor Rates, including available investment returns, the cost of our risk management techniques, sales commissions, administrative expenses, regulatory and tax requirements, general economic trends, and competitive factors. We determine the Buffer Rates and Floor Rates at our sole discretion, and the Buffer Rate or Floor Rate is guaranteed to never change on a particular Segment Option as long as the Segment Option is available.

Misstatement of Age or Gender

If the age or, where applicable, gender of the Annuitant has been misstated, we adjust the annuity benefit payment under your Contract to reflect the amount that would have been payable at the correct age and gender. If we make any overpayment because of incorrect information about age or gender, or any error or miscalculation, we deduct the overpayment from the next annuity benefit payment(s) due. Underpayments are added to the annuity benefit payment.

Assignment

If your Contract is part of your qualified plan, IRA, SEP, or SIMPLE-IRA, you may not assign ownership.

You may assign ownership of your Non-qualified Contract. Each assignment is subject to any payments made or action taken by the Company prior to our notification of the assignment. We assume no responsibility for the validity of any assignment. An assignment or pledge of a Contract may have adverse tax consequences.

An assignment must be made in writing and filed with us at our Home Office. The irrevocable beneficiary(ies), if any, must authorize any assignment in writing. Your rights, as well as those of the Annuitant and beneficiary, are subject to any assignment on file with us. Any amount paid to an assignee is treated as a partial Surrender and is paid in a single payment.

The Company may refuse any assignment or transfer at any time on a non-discriminatory basis.

Contract Termination

We reserve the right to terminate the Contract and make a single payment (without imposing any charges) to you if your Accumulated Value at the end of the accumulation period is less than $2,000. Termination of the Contract will not unfairly discriminate against the Owner.

Reinstatement

Reinstatement is only available for full withdrawal of your Contract. You cannot reinstate a partial withdrawal or partial Annuitization.

If you have requested to replace this Contract with an annuity contract from another company and want to reinstate this Contract, the following apply:

•we reinstate the Contract effective on the original Surrender date;

•we apply the amount received from the other company (“reinstatement amount”) and the amount of the Surrender Charge you paid when you Surrendered the Contract;

•the reinstatement amount is placed into an account with a fixed interest rate on the Valuation Day;

•the reinstatement amount and any interest credited to it will be held in the fixed interest rate account until the next Segment Anniversary, at which point you can elect to transfer the amount to any available Segment Option(s), subject to any restrictions that were applicable under your original Contract;

•commissions are not paid on the reinstated amounts; and

•a new Data Page is sent to your address of record.

We follow procedures in an attempt to assure genuine telephone service and internet transactions. If these procedures are not followed, we may be liable for loss caused by unauthorized or fraudulent transactions. The procedures may include recording telephone service transactions, requesting personal identification (for example, name, address, security phrase, password, daytime telephone number, or birth date) and sending written confirmation to your address of record.

Important Information About Customer Identification Procedures

To help the government fight the funding of terrorism and money laundering activities, Federal law requires financial institutions to obtain, verify, and record information that identifies each person who applies for a Contract. When you apply for a Contract, we will ask for your name, address, date of birth, and other information that will allow us to verify your identity. We may also ask to see your driver’s license or other identifying documents.

If concerns arise with verification of your identification, no transactions will be permitted while we attempt to reconcile the concerns. If we are unable to verify your identity within 30 days of our receipt of your Total Premium Payment, the Contract will be terminated and any value surrendered in accordance with normal procedures.

We do not knowingly sell annuities that are for the benefit of a business/organization that is illegal under Federal and/or State law (such as a marijuana clinic), or a person who owns or receives income from such an entity or whose source of funds is illegal.

State Regulation

The Company is subject to the laws of the State of Iowa governing insurance companies and to regulation by the Iowa Insurance Division. An annual statement in a prescribed form must be filed by March 1 in each year covering our operations for the preceding year and our financial condition on December 31 of the prior Contract Year. Our books and assets are subject to examination by the Commissioner of Insurance of the State of Iowa, or the Commissioner’s representatives, at all times. A full examination of our operations is conducted periodically by the National Association of Insurance Commissioners. Iowa law and regulations also prescribe permissible investments, but this does not involve supervision of the investment management or policy of the Company.

In addition, we are subject to the insurance laws and regulations of other states and jurisdictions where we are licensed to operate. Generally, the insurance departments of these states and jurisdictions apply the laws of the state of domicile in determining the field of permissible investments.

SG SMART CLIMATE INDEX

Summary

The SG Smart Climate Index (Bloomberg Ticker: SGIXSMAC) is a rules-based index that aims to provide investment exposure to the performance of stocks of U.S. large-capitalization companies that are selected based on proprietary climate risk preparedness scores and certain environmental, social, and governance (ESG) exclusion filters. Climate risk generally refers to the risk of negative impacts on a company’s business or financial condition due to climate-related conditions around the globe or the transition to a lower carbon economy. The climate risk models used in connection with the Index seek to identify large U.S. companies that are more likely to perform well in future climate scenarios.

The Index is an “excess return” index. The Index’s return reflects the total return on an investment in the underlying component stocks (including reinvestment of all dividends, interest, and other income), less certain negative adjustments and deductions that reduce the performance of the Index. See “Performance Drags” below.

The sponsor of the Index and the Underlying SGI Index (as defined below) is Société Générale. The index calculator is S&P Opco, LLC (a subsidiary of S&P Dow Jones Indices LLC). The climate risk models used in connection with the Index are produced by Entelligent, Inc. On January 12, 2022, Societe Generale, through an indirect wholly owned subsidiary, acquired a passive ownership interest and a board seat in Entelligent, Inc. Sustainalytics provides the data used to support the ESG exclusion filters. None of these companies are affiliated with Principal.

Underlying SGI Index

The Index is composed of a single underlying index, the SG Climate Transition Risk Index (Bloomberg Ticker: SGIXCTR) (the “Underlying SGI Index”). The Underlying SGI Index is a weighted index comprised of 150 to 250 stocks selected from the S&P 500 Index. The Underlying SGI Index is a “gross total return” index, meaning that its return reflects the total return on an investment in the component stocks (including reinvestment of all dividends, interest, and other income), less the fixed replication costs described under “Performance Drags” below.

Stocks are selected and weighted for the Underlying SGI Index using the following three-step process:

•Step One – ESG Exclusion Filters: Starting with all the companies included in the S&P 500 Index, proprietary filters are applied to exclude companies that fail to pass certain ESG criteria. Based on these filters, the following companies may be excluded from the Underlying SGI Index:

◦Companies involved in major controversies (i.e., operations incidents, employee incidents, governance incidents) that have an impact on the environment and society, and associated business risks;

◦Companies involved in a range of products, services, or business activities that are generally viewed as being controversial (e.g., weapons, tobacco, alcohol, gambling, thermal coal, fossil fuel, genetically modified organisms); and

◦Companies breaching any U.N. Global Compact Principles, which set forth principles related to human rights, labor, environment, and anti-corruption.

Companies involved in a major controversy or controversial business activity may not always be excluded. The ESG exclusion filters take into account the degree of involvement. For example, oil companies with substantive investments in a clean energy future may not be excluded. However, companies involved in certain business activities beyond specific thresholds (e.g., 0% of revenues from sale of assault weapons, 5% revenues from extraction of thermal coal, 10% of revenues from sale of tobacco products), and any company in breach of a U.N Global Compact Principle, will be excluded.

•Step Two – Climate Risk Scoring: Each company remaining after step one is assigned a climate risk score. Climate risk scores are calculated using proprietary models that predict company profitability and share price performance under different climate scenarios in the future. Within each Global Industry Sector

A - 3

Classification, the companies are ranked by their respective climate risk scores, with the best scoring companies on the top and the worst scoring companies on the bottom. Companies ranked in the top half for each Global Industry Sector Classification are selected for inclusion in the Underlying SGI Index.

•Step Three – Weighting: Component stocks of companies with better climate risk scores receive higher weightings than those of companies with worse climate risk scores, subject to minimum and maximum weighting restrictions designed to limit sector bias and provide diversification.

The Underlying SGI Index is reconstituted using the three-step process described above on a quarterly basis. The selection and weighting of stocks for the Underlying SGI Index is fully systematic and rules-based.

Performance Drags

The performance of the Index reflects certain deductions, all of which serve to reduce Index Levels:

1.The Index’s return reflects a negative performance adjustment equal to 1.50%, as an annualized percentage of Index Value, in the form of a “synthetic dividend.” It is applied daily and is intended to replicate the impact that an annual dividend of 1.50% would have on the Index Level. This “synthetic dividend” is not a dividend paid by the underlying component stocks and is not an amount payable to you. It only serves to reduce the performance of the Index.

1.Assumed fixed replication costs are deducted from the performance of the Underlying SGI Index. These costs equal 0.50%, as an annualized percentage of the index level, and are deducted on a daily basis. These assumed costs are intended to represent the costs that would be incurred in connection with replicating the performance of the Underlying SGI Index.

1.The performance of the Index reflects the return on an investment in the underlying component stocks through the use of borrowed funds. The assumed costs of borrowing are deducted from the Index Level. The assumed costs of borrowing are deducted on a daily basis and equal the current U.S. Federal Funds Rate as reported on Bloomberg. The U.S. Federal Funds Rate is the rate of interest that banks charge each other for short-term loans.

License

Use of the Index in connection with annuity contracts has been licensed to Principal. The licensing agreement has an initial term ending on or about [to be added by amendment], and thereafter automatically renews annually unless terminated by either party.

New Index

This Index and the Underlying SGI Index have limited performance histories, dating back to September 7, 2022 and April 2, 2022, respectively. There is less publicly available information about the Index and the Underlying SGI Index compared to more established market indexes.

The aggregate number of shares of stock which the corporation is authorized to issue is 6,000,000 shares, consisting of (a) 5,000,000 shares of common stock, par value $1.00 per share (the "Common Stock"), and (b) 1,000,000 shares of preferred stock, par value $1.00 per share (the "Preferred Stock"), issuable in one or more series.

SECTION 2. The Board of Directors of the corporation is hereby expressly authorized, at any time and from time to time, to divide the shares of Preferred Stock into one or more series, to issue from time to time in whole or in part the shares of Preferred Stock or the shares of any series thereof, and in the resolution or resolutions providing for the issue of shares of Preferred Stock or of a particular series to fix and determine the voting powers, full or limited, or no voting powers, and such designations, preferences and relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof that may be desired, to the fullest extent now or hereafter permitted by Section 602 of Chapter 490 of Title XII of the Iowa Code ("Chapter 490"), as amended from time to time, and the other provisions of these Articles of Incorporation; provided, however, that in no event shall Preferred Stock have more than one vote per share of Preferred Stock.

SECTION 3. Subject to any other provisions of these Amended and Restated Articles of Incorporation, holders of Common Stock shall be entitled to receive such dividends and other distributions in cash, stock or property of the corporation as may be declared thereon by the Board of Directors from time to time out of assets or funds of the corporation legally available therefor.

SECTION 4. No shareholder of the corporation shall be entitled to exercise any right of cumulative voting.

SECTION 5. No shareholder of the corporation shall have any preemptive or preferential right, nor be entitled as a matter of right to subscribe for or purchase any part of any new or additional issue of stock of the corporation of any class or series, whether issued for money or for consideration other than money, or of any issue of securities convertible into stock of the corporation.

SECTION 6. The corporation shall be entitled to treat the person in whose name any share of its stock is registered as the owner thereof for all purposes and shall not be bound to recognize any equitable or other claim to, or interest in, such share on the part of any other person, whether or not the corporation shall have notice thereof, except as expressly provided by applicable law.

SECTION 7. The corporation shall not issue any shares of Voting Stock (as hereinafter defined) of the corporation or securities convertible into Voting Stock of the corporation to persons other than Principal Financial Services, Inc. ("Principal Financial Services") if, as a result of such issuance, the issued and outstanding Voting Stock of the corporation not held by Principal Financial Services equals or exceeds that held by Principal Financial Services. For purposes of this Section 7, "Voting Stock" means securities of any class or any ownership interest having voting power for the election of directors of the corporation, other than securities having voting power only to elect additional directors only because of the occurrence of a contingency. For purposes of the limitations set forth in this Article VI, any issued and outstanding securities of the corporation that are convertible into Voting Stock are considered issued and outstanding Voting Stock of the corporation as though such convertible securities had been converted into Voting Stock in accordance with their terms.

ARTICLE VII.

The corporate powers of the corporation (except as at the time otherwise provided by law, these Amended and Restated Articles of Incorporation or the By-Laws of the corporation) shall be exercised by the Board of Directors, and by such officers and agents as the Board of Directors may authorize, elect or appoint. Subject to the rights of any holders of any class or series of Preferred Stock to elect additional directors under specified circumstances, the Board of Directors shall consist of not less than nine nor more than 21 directors, the number to be determined from time to time by the shareholders or a majority of the entire Board of Directors. The Board of Directors, other than with respect to those directors who may be elected by the holders of any class or series of Preferred Stock, shall be divided into three classes, as nearly equal numerically as possible, determined by terms expiring in successive years. Each director shall serve a term of approximately three years except as otherwise provided or where it is necessary to fix a shorter term in order to preserve classification. The term of office of each director shall begin at the annual meeting at which such director is elected or at the time elected by the Board of Directors. No decrease in the number of directors shall shorten the term of any incumbent director. Each director shall serve until a successor is duly elected and qualified and shall be eligible for re-election. Subject to the rights of any holders of any class or series of Preferred Stock to elect additional directors under specified circumstances, any vacancy or vacancies on the Board of Directors may be filled by the shareholders, by the Board of Directors at any meeting of the Board of Directors or, if the directors remaining in office constitute fewer than a quorum of the Board of Directors, by the affirmative vote of a majority of directors remaining in office. The term of office of each director of the corporation shall not extend beyond the annual meeting of the corporation next following the date

such director attains age 72, or such younger age as may be established for all directors by the Board of Directors. Members of the Board of Directors shall not be required to be policyowners of the corporation.

Subject to the rights of any holders of any class or series of Preferred Stock to elect additional directors under specified circumstances, any director may be removed, but only for cause, at a meeting of shareholders called for that purpose in the manner prescribed by law, upon the affirmative vote of the holders of a majority of the combined voting power of the then outstanding stock of the corporation entitled to vote generally in the election of directors.

The Board of Directors shall have the power without the assent or vote of the shareholders of the corporation to adopt such By-Laws and rules and regulations for the transaction of the business of the corporation not inconsistent with these Amended and Restated Articles of Incorporation or the laws of the State of Iowa, and to amend, alter or repeal such By-Laws, rules and regulations. In addition to any requirements of law and any other provision of these Articles of Incorporation, the shareholders of the corporation may adopt, amend, alter or repeal the By-Laws of the corporation upon the affirmative vote of holders of more than 50% of the combined voting power of the outstanding stock of the corporation entitled to vote generally in the election of directors. Advance notice of nominations for the election of directors and of business to be brought by shareholders before any meeting of shareholders of the corporation shall be given in the manner and to the extent provided in the By-Laws of the corporation. The Board of Directors may fix reasonable compensation of the directors for their services. The Board of Directors shall elect a President, and shall authorize, elect or appoint such other officers, agents or committees as in their judgment may be necessary or advisable.

A director, in determining what is in the best interests of the corporation when considering a proposal of acquisition, merger or consolidation of the corporation or a similar proposal, may consider any or all of the following community interest factors, in addition to consideration of the effects of any action on shareholders: (i) the effects of action on the corporation's employees, suppliers, creditors and customers; (ii) the effects of the action on the communities in which the corporation and its subsidiaries operate; and (iii) the long-term as well as short-term interests of the corporation and its shareholders, including the possibility that these interests may be best served by the continued independence of the corporation.

If on the basis of the community interest factors described above, the Board of Directors of the corporation determines that a proposal to acquire or merge the corporation is not in the best interests of the corporation, it may reject the proposal. If the Board of Directors of the corporation determines to reject any such proposal, the Board of Directors has no obligation to facilitate, to remove any barriers to or to refrain from impeding the proposal. Consideration of any or all of the community interest factors is not a violation of the business judgment rule or of any duty of the director to the shareholders, or a group of shareholders, even if the director reasonably determines that a community interest factor or factors outweigh the financial or other benefits to the corporation or a shareholder or group of shareholders.

ARTICLE VIII.

The corporation shall indemnify directors, officers, employees and agents of the corporation as provided in Sections 850 through 858 of Chapter 490, subject to such limitations as may be established by the Board of Directors. Any repeal or modification of this Article VIII or of Sections 850 through 858 of Chapter 490 shall not adversely affect any right of indemnification of a director, officer, employee or agent of the corporation existing at any time prior to such repeal or modification.

ARTICLE IX.

A director of the corporation shall not be personally liable to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director, except for liability (a) for a breach of the director's duty of loyalty to the corporation or its shareholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, (c) for a transaction from which the director derives an improper personal benefit or (d) under Section 833 of Chapter 490, as amended from time to time. If Chapter 490 is hereafter amended to authorize the further elimination or limitation of the liability of directors, then the liability of a director of the corporation, in addition to the limitation on personal liability provided herein, shall be eliminated or limited to the extent of such amendment, automatically and without any further action, to the maximum extent permitted by law. Any repeal or modification of the provisions of this Article IX by the shareholders of the corporation shall be prospective only and shall not adversely affect any limitation in the personal liability or any other right or protection of a director of the corporation with respect to any state of facts existing at or prior to the time of such repeal or modification.

ARTICLE X.

Effective as of such time as the Common Stock shall be registered pursuant to the provisions of the Securities Exchange Act of 1934, as amended, any action required or permitted to be taken by the shareholders of the corporation must be effected at a duly called annual or special meeting of the shareholders of the corporation, and the ability of the shareholders to consent in writing to the taking of any action is specifically denied.

ARTICLE XI.

Amendments to these Articles of Incorporation are subject to the approval of the Iowa Insurance Commissioner and the Iowa Attorney General as provided in Section 508.4 of Title XIII of the Iowa Code.

MEETINGS OF SHAREHOLDERS

Section 3.1 Annual Meeting. The annual meeting of the shareholders for the election of directors and for the transaction of such other business as may properly come before the meeting, shall be held on the third Monday in May of each year at such place and time as the Board of Directors shall each year fix, or at such other place, time and date as the Board of Directors shall fix.

Section 3.2 Special Meetings. Special meetings of the shareholders, for any purpose or purposes, unless otherwise prescribed by law (which for purposes of these By-Laws shall mean as required from time to time by the Iowa Business Corporation Act or the Articles of Incorporation of the corporation), may be called by the Chairman of the Board, the Chief Executive Officer or the Board of Directors, and shall be called by the Board of Directors upon the written demand, signed, dated and delivered to the Secretary, of the holders of at least 10% of all the votes entitled to be cast on any issue proposed to be considered at the meeting. Such written demand shall state the purpose or purposes for which such meeting is to be called. The time, date and place of any special meeting shall be determined by the Board of Directors, or, at its direction, by the Chief Executive Officer.

Section 3.3 Notices and Reports to Shareholders.

(a) Notice of the place, date and time of all meetings of shareholders and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be communicated not fewer than 10 days nor more than 60 days before the date of the meeting to each shareholder entitled to vote at such meeting. The Board of Directors, as provided in Section 3.6 of these By-Laws, may establish a record date for the determination of shareholders entitled to notice. Notice of adjourned meetings need only be given if required by law or Section 3.8 of these By-Laws.

(b) If notice of proposed corporate action is required by law to be given to shareholders not entitled to vote and the action is to be taken by consent of the voting shareholders, the corporation shall give all shareholders written notice of the proposed action at least 10 days before the action is taken. The notice must contain or be accompanied by the same material that would have been required by law to be sent to shareholders not entitled to vote in a notice of meeting at which the proposed action would have been submitted to the shareholders for action.

(c) In the event corporate action is taken without a meeting in accordance with the Articles of Incorporation of the corporation and Section 3.13 of these By-Laws by less than unanimous written consent, prompt notice of the taking of such corporate action shall be given to those shareholders who have not consented in writing to the taking of such corporate action.

Section 3.4 Notice of Shareholder Business and Nominations.

(a)Annual Meetings of Shareholders. (i) Nominations of persons for election to the Board of Directors and the proposal of business to be considered by the shareholders may be made at an annual meeting of shareholders of the corporation (1) by or at the direction of the Board of Directors or the Chairman of the Board or (2) by any shareholder of the corporation who is entitled to vote at the meeting, who complies with the notice procedures set forth in clauses (ii) and (iii) of this paragraph (a) of Section 3.4 and who was a shareholder of record at the time such notice was delivered to the Secretary.

(ii)For nominations or other business to be properly brought before an annual meeting by a shareholder pursuant to clause (2) of paragraph (a)(i) of this Section 3.4, the shareholder must have given timely notice thereof in writing to the Secretary. To be timely, a shareholder's notice shall be delivered to the Secretary at the principal executive offices of the corporation not less than 90 days nor more than 120 days prior to the first anniversary of the preceding year's annual meeting; provided, however, that if the date of the annual meeting is advanced by more than 20 days or delayed by more than 70 days from such anniversary date, notice by the shareholder to be timely must be so

delivered not earlier than 120 days prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made. In no event shall the adjournment of an annual meeting commence a new time period for the giving of a shareholder's notice as described above. Such shareholder's notice shall set forth (1) as to each person whom the shareholder proposes to nominate for election or reelection as a director all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors or is otherwise required pursuant to Regulation 14A under Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 14a-11 thereunder, including such person's written consent to being named in the proxy statement as a nominee and to serving as a director if elected; (2) as to any other business that the shareholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting and any material interest in such business of such shareholder and of any beneficial owner on whose behalf the proposal is made; and (3) as to the shareholder giving the notice and any beneficial owner on whose behalf the nomination or proposal is made (A) the name and address of such shareholder, as they appear on the corporation's books, and of such beneficial owner and (B) the class and number of shares of the corporation which are owned beneficially and of record by such shareholder and such beneficial owner.

(iii) Notwithstanding anything in the second sentence of paragraph (a)(ii) of this Section 3.4 to the contrary, in the event that the number of directors to be elected to the Board of Directors is increased and there is no public announcement naming all of the nominees for director or specifying the size of the increased Board of Directors made by the corporation at least 100 days prior to the first anniversary of the preceding year's annual meeting, a shareholder's notice under this Section 3.4 shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the corporation not later than the close of business on the 10th day following the day on which such public announcement is first made by the corporation.

(b)Special Meetings of Shareholders. Only such business as shall have been brought before the special meeting of the shareholders pursuant to the corporation's notice of meeting pursuant to Section 3.3 of these By-Laws shall be conducted at such meeting. Nominations of persons for election to the Board of Directors may be made at a special meeting of shareholders at which directors are to be elected pursuant to the corporation's notice of meeting (i) by or at the direction of the Board of Directors or (ii) by any shareholder of the corporation who is entitled to vote at the meeting, who complies with the notice procedures set forth in this paragraph (b) of Section 3.4 and who is a shareholder of record at the time such notice is delivered to the Secretary. Nominations by shareholders of persons for election to the Board of Directors may be made at such special meeting of shareholders if the shareholder's notice as required by paragraph (a)(ii) of this Section 3.4 shall be delivered to the Secretary at the principal executive offices of the corporation not earlier than the 120th day prior to such special meeting and not later than the close of business on the later of the 90th day prior to such special meeting or the 10th day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting. In no event shall the adjournment of special meeting commence a new time period for the giving of a shareholder's notice as described above.

(c)General. (i) Only persons who are nominated in accordance with the procedures set forth in this Section 3.4 shall be eligible to serve as directors and only such business shall be conducted at a meeting of shareholders as shall have been brought before the annual or special meeting in accordance with the procedures set forth in this Section 3.4. Except as otherwise provided by law, the Articles of Incorporation of the corporation or these By-Laws, the chairperson of the annual or special meeting shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made in accordance with the procedures set forth in this Section 3.4 and, if any proposed nomination or business is not in compliance with this Section 3.4, to declare that such defective proposal or nomination shall be disregarded.

(ii)For purposes of this Section 3.4, "public announcement" shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or (15(d) of the Exchange Act.

(iii)Notwithstanding the foregoing provisions of this Section 3.4, a shareholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section 3.4. Nothing in this Section 3.4 shall be deemed to affect any rights of (1) shareholders to request inclusion of proposals in the corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act or (2) the holders of any series of Preferred Stock to elect directors if so provided under any applicable certificates of designation relating to the series of Preferred Stock.

Section 3.5 Waiver of Notice.

(a)Any shareholder may waive any notice required by law or these By-Laws if such waiver is in writing and signed by the shareholder entitled to such notice, whether before or after the date and time stated in such notice. Such a waiver shall

be equivalent to notice to such shareholder in due time as required by law or these By-Laws. Any such waiver shall be delivered to the corporation for inclusion in the minutes or filing with the corporate records of the corporation.

(b)A shareholder's attendance at a meeting, in person or by proxy, waives (i) objection to lack of notice or defective notice of such meeting, unless the shareholder at the beginning of the meeting or promptly upon the shareholder's arrival objects to holding the meeting or transacting business at the meeting and (ii) objection to consideration of a particular matter at the meeting that is not within the purpose or purposes described in the meeting notice, unless the shareholder objects to considering the matter when it is presented.

Section 3.6 Record Date. The Board of Directors may fix, in advance, a date as to the record date for any determination of shareholders for any purpose, such date in every case to be not more than 70 days prior to the date on which the particular action or meeting requiring such determination of shareholders is to be taken or held. If no record date is so fixed for the determination of shareholders, the close of business on the day before the date on which the first notice of a shareholders' meeting is communicated to shareholders or the date on which the Board of Directors authorizes a share dividend or a distribution (other than one involving a repurchase or reacquisition of shares), as the case may be, shall be the record date for such determination of shareholders. When a determination of shareholders entitled to vote at any meeting of shareholders has been made as provided in this Section 3.6, such determination shall apply to any adjournment thereof, unless the Board of Directors selects a new record date or unless a new record date is required by law.

Section 3.7 Shareholders' List. After fixing a record date for a meeting, the corporation shall prepare an alphabetical list of the names of all shareholders who are entitled to notice of a shareholders' meeting. The list must be arranged by voting group and within each voting group by class or series of shares, and show the address of and number of shares held by each shareholder. The shareholders' list must be available for inspection by any shareholder beginning two business days after notice of the meeting is given for which the list was prepared and continuing through the meeting at the corporation's principal office or at a place in the city where the meeting will be held which such place shall be identified in the notice of the meeting. A shareholder, or a shareholder's agent or attorney, is entitled on written demand to inspect and, subject to the requirements of law, to copy the list, during regular business hours and at the person's expense, during the period the list is available for inspection. The corporation shall make the shareholders' list available at the meeting, and any shareholder, or a shareholder's agent or attorney, is entitled to inspect the list at any time during the meeting or any adjournment thereof.

Section 3.8 Quorum.

(a)At any meeting of the shareholders, a majority of the votes entitled to be cast on the matter by a voting group constitutes a quorum of that voting group for action on that matter, unless the representation of a different number is required by law, and in that case, the representation of the number so required shall constitute a quorum. If at the time for which a meeting of shareholders has been called less than a quorum is present, the chairperson of the meeting or a majority of the shareholders present or represented by proxy and entitled to vote thereat may adjourn the meeting to another place, date or time.

(b) When a meeting is adjourned to another place, date or time, notice need not be given of the adjourned meeting if the place, date and time thereof are announced at the meeting at which the adjournment is taken; provided, however, that if the date of any adjourned meeting is more than 120 days after the date for which the meeting was originally noticed, or if a new record date is fixed for the adjourned meeting, notice of the place, date and time of the adjourned meeting shall be given in conformity with these By-Laws. At any adjourned meeting, any business may be transacted which might have been transacted at the original meeting.

(c)Once a share is represented for any purpose at a meeting, it is deemed present for quorum purposes for the remainder of the meeting and for any adjournment thereof unless a new record date is or must be set for that adjourned meeting.

Section 3.9 Organization.

(a)The Chairman of the Board, or in the absence of the Chairman of the Board, the acting Chairman of the Board, or in his or her absence, such person as shall be designated by the holders of a majority of the votes present at the meeting shall call meetings of the shareholders to order and shall act as presiding officer of such meetings.

(b)The Secretary shall act as secretary at all meetings of the shareholders, but in the absence of the Secretary at any meeting of the shareholders, the presiding officer may appoint any person to act as secretary of the meeting.

Section 3.10 Voting of Shares.

(a)Every shareholder entitled to vote may vote in person or by proxy. Except as provided in subsection (c) of this Section 3.10 or unless otherwise provided by law, each outstanding share, regardless of class, shall be entitled to one vote on each matter submitted to a vote at a meeting of shareholders. Unless otherwise provided by law, directors in each class shall be elected by a plurality of the votes cast by the shares entitled to vote in the election at a meeting at which a quorum is present.

Shareholders do not have the right to cumulate their votes for directors unless the Articles of Incorporation of the corporation so provide.

(b)The shareholders having the right to vote shares at any meeting shall be only those of record on the stock books of the corporation on the record date fixed by law or pursuant to the provisions of Section 3.6 of these By-Laws.

(c)Absent special circumstances, the shares of the corporation held, directly or indirectly, by another corporation are not entitled to vote if a majority of the shares entitled to vote for the election of directors of such other corporation is held by the corporation. The foregoing does not limit the power of the corporation to vote any shares held by the corporation in a fiduciary capacity.

(d)If a quorum exists, action on a matter other than the election of directors, by a voting group is approved if the votes cast within the voting group favoring the action exceed the votes cast opposing the action, unless a greater number is required by law.

Section 3.11 Voting by Proxy or Representative.

(a)At all meetings of the shareholders, a shareholder entitled to vote may vote in person or by proxy appointed in writing, which appointment shall be effective when received by the secretary of the meeting or other officer, agent or inspector authorized to tabulate votes. An appointment of a proxy is valid for 11 months from the date of its execution, unless a longer period is expressly provided in the appointment form.

(b)Shares held by an administrator, executor, guardian, conservator, receiver, trustee, pledgee or another corporation may be voted as provided by law.

Section 3.12 Conduct of Business. The person acting as the presiding officer of any meeting of shareholders shall determine the order of business and procedure at the meeting, including such regulation of the manner of voting and the conduct of business as seem to him or her to be in order.

Section 3.13 Action Without Meeting. Except as otherwise set forth in this Section 3.13 and subject to Section 3.3(c) of these By-Laws and the Articles of Incorporation of the corporation, any action required or permitted by law to be taken at a meeting of the shareholders of the corporation may be taken without a meeting or vote, and without notice, if one or more consents in writing setting forth the action taken shall be signed and dated by the holders of outstanding shares having not less than 90% of the votes entitled to be cast at a meeting at which all shares entitled to vote on the action were present and voted, and are delivered to the corporation for inclusion in the minutes or filing with the corporate records of the corporation; provided, however, that a director shall not be removed by written consents unless written consents are obtained from the holders of all of the outstanding shares of the corporation that are entitled to vote on the removal of the director. Written consents from a sufficient number of shareholders must be obtained within 60 days from the date of the earliest dated consent for such consents to be effective to take corporate action. If not otherwise fixed by law or in accordance with these By-Laws, the record date for determining shareholders entitled to take action without a meeting is the date the first shareholder signs such a written consent.

YOUR CONTRACT VALUES

The Accumulated Value is the sum of the Segment Interim Value plus the total value of any allocation to the Initial Holding Account and fixed Segment Option(s).

The Segment Interim Value is the Crediting Base adjusted for any applicable Equity Adjustment per Segment Option excluding fixed Segment Option(s).

CREDITING BASE

The Crediting Base is the value of the Segment Option on the Segment Start Date reduced by an adjustment for Surrenders and any applicable fee(s).

The adjustment for each Surrender (and any applicable Surrender Charges and fees) will reduce the Crediting Base in the same proportion that the Accumulated Value was reduced on the date of the Surrender. The adjustment for the Surrender is equal to (1 divided by 2) multiplied by 3, where:

1.Is the amount of the Surrender (and any applicable Surrender Charges and fees); and

2.Is the Accumulated Value immediately prior to the Surrender, and

3.Is the Crediting Base immediately prior to the Surrender.

EQUITY ADJUSTMENT

The Equity Adjustment is the adjustment (which could be positive, negative, or equal to zero) to the Accumulated Value, expressed as a percentage, based on the change in the fair value of the hypothetical derivative assets designed to replicate credits provided by a Segment Option at the end of a Segment Term. The fair values of the hypothetical derivative assets are calculated by Us and are used to estimate the change in the market value of

each Segment Option. The Equity Adjustment does not apply to the Initial Holding Account or the fixed Segment Option(s).

BOND ADJUSTMENT

The Bond Adjustment is an adjustment (which could be positive, negative, or equal to zero) to the Accumulated Value for a Surrender based on the change in the fair value of the hypothetical fixed income assets supporting the contract. The fair value of the hypothetical fixed income assets is designed to represent the market value of the assets backing each Segment Option except for the derivative assets.

The Bond Adjustment Index is shown on the Data Page. If this Bond Adjustment Index becomes unavailable or the method of calculating these values substantially changes. We may choose another Bond Adjustment Index and You will be made aware of the change. The initial beginning Bond Adjustment Index Value is equal to the closing price of this Index on the Contract Date. Each beginning Bond Adjustment Index Value after the initial one is equal to the closing price of this Index on the Segment Anniversary divisible by six. The Current Bond Adjustment Index Value is equal to the most recent closing price of this Index on the day the adjustment is calculated. The first Bond Adjustment period begins on the first Segment Start Date, and it restarts on each Segment Anniversary divisible by six.

SEGMENT CREDITS

Segment Credits will be calculated for a Segment Option based on the provisions of the applicable Segment Endorsement. The Segment Credit will be calculated and applied to the Crediting Base only on the Segment End Date. Segment Credits could be negative, meaning You could lose principal and/or prior earnings.

OPTIONS AVAILABLE ON A SEGMENT END DATE

On Your Segment End Date, subsequent Segment Option(s) available to You will be declared by Us and may or may not include the previously offered Segment Option(s). We reserve the right to offer alternative Segment Options or to discontinue a Segment Option in the future.

On Your Segment End Date, You may allocate Your Accumulated Value into any of the available Segment Option(s) We are offering at that time, subject to the Segment Minimum on the Data Page. We will notify You of the Segment Option(s) available in advance of Your Segment End Date. At least one Segment Option will be made available.

If You do not elect a new Segment Option by Your Segment End Date, the Accumulated Value will automatically be allocated to the same Segment Option to which it is currently allocated. If We no longer offer the same Segment Option, We will select a new Segment Option from those that We do offer. The Segment Option selected will be one with the same Index with a 1-year Segment Term. If the same Index is no longer available, then Accumulated Value will be allocated to the Fixed Segment Option if You do not elect a new Segment Option by Your Segment End Date.

Segment Option(s) with Segment Term(s) that would extend beyond the next Segment Anniversary divisible by six or beyond the Annuitization Date will not be available. Segment Option(s) You are currently allocated to and that will not be at the Segment End Date on the next Segment Anniversary will not be available to transfer in to.

SEGMENT TRANSFERS

You may transfer amounts among the Segment Options only at Your Segment End Date, which occurs prior to the Annuitization Date. At Your Segment End Date You may elect to transfer some or all of the Accumulated Value, subject to the Segment Minimum shown on the Data Page, from one Segment Option to another available Segment Option as provided in this section. To request a transfer, Your request must be provided to Us in Good Order two Valuation Days prior to Your Segment End Date.

1.You must specify the dollar amount or percentage to transfer to and from each Segment Option subject to the Segment Minimum shown on the Data Page.

2.The Accumulated Value of each Segment Option must be equal to or greater than the Segment Minimum shown on the Data Page.

3.We reserve the right to limit the number of Segment Options from which scheduled transfers may be made at the same time.

If you request a transfer prior to the Segment End Date and the Segment Option the Accumulated Value is being transferred to becomes unavailable before the Segment Start Date, We will notify You of the change in available Segment Options, and You must provide Us with a new transfer request in Good Order two Valuation Days prior to the Segment End Date.

Transfers will be effective on the next Segment Start Date.

FULL SURRENDER

You may Surrender this contract in full for the Surrender Value. The Surrender Value at any time is the Accumulated Value on the date We receive Your Notice in Good Order adjusted for the Bond Adjustment, less any applicable Surrender Charge and other fees and charges.

PARTIAL SURRENDERS

You may take unscheduled and scheduled partial Surrenders of this contract by providing Us Notice. Partial Surrenders reduce the Accumulated Value of the contract and are deducted proportionately from the Segment Options, unless You direct otherwise. The deductions are based on the values as of the end of day of the effective date of the Surrender.

Partial Surrenders that exceed the remaining Free Surrender Amount for that Contract Year are subject to any applicable Surrender Charge. If the partial Surrender amount is less than the remaining Free Surrender Amount for that Contract Year, no Surrender Charge will apply.

Any partial Surrender that would reduce the Accumulated Value to less than the Minimum Accumulated Value After A Partial Surrender amount shown on the Data Page will be treated as a request for Surrender of this contract.

If the Owner or any Joint Owner dies prior to the Annuitization Date, the death benefit may be distributed in a lump sum or within five years of the date of death or distributed over a time period not extending beyond the life expectancy of the beneficiary as provided for in Internal Revenue Code (“IRC”) section 72(s), as may be amended from time to time. If payments are made over the life expectancy of the beneficiary, they must begin not later than one year after the date of death of the Owner or Joint Owner.

If the Owner or Joint Owner dies on or after the Annuitization Date and before the entire interest in this contract has been distributed, the remaining portion of such interest will be distributed at least as rapidly as required under applicable federal tax laws, including, particularly, IRC section 72(s), as may be amended from time to time.

Notwithstanding any provision to the contrary in this contract, any payment of death benefits must comply with all applicable laws, including IRC section 72(s), as may be amended from time to time.

DEATH OF OWNER(S)

The following provisions apply upon an Owner’s death if a contract is not jointly owned:

1.If the surviving spouse is the only primary beneficiary, the surviving spouse may elect to become the Owner and continue the contract or elect to receive the death benefit.

2.If the primary beneficiary is not the surviving spouse, the primary beneficiary will receive the death benefit.

The following provisions apply upon the death of the first Joint Owner to die when a contract is jointly owned:

1.The surviving Joint Owner will be treated as the primary beneficiary. Any other beneficiary designation on record will be treated as contingent beneficiary.

2.If the surviving Joint Owner is the spouse of the deceased Joint Owner, the surviving spouse may elect to become the Owner and continue the contract or elect to receive the death benefit.

DEATH OF ANNUITANT(S)

If an Annuitant who is not an Owner dies while this contract is in force, a new Annuitant may be named unless the Owner is a corporation, trust, or other entity.

If the Owner is a corporation, trust or other entity, the death benefit will be payable upon the death of the Annuitant, or, in the case of Joint Annuitants, upon the death of the first Joint Annuitant to die.

STANDARD DEATH BENEFIT

Unless otherwise provided by a rider to this contract, if the age of the oldest owner at the time the application is signed is 79 or younger, the death benefit is equal to the greater of 1 or 2 where:

1.Is the Accumulated Value, adjusted for the Bond Adjustment, on the date We receive the proof of death and all required documents in Good Order; or

2.Is the total Premium Payment minus an adjustment for each partial Surrender (and any applicable Surrender Charge and fees) and an adjustment for each partial Annuitization made prior to the date We receive the poof of death and all required documents.

Unless otherwise provide by a rider to this contract, if the age of the oldest Owner at the time the application is signed is 80 or older, the death benefit is equal to the Accumulated Value, adjusted for the Bond Adjustment, on the date We receive the proof of death and all required documents in Good Order.

The adjustment for each partial Surrender (and any applicable Surrender Charges and fees) and for each partial Annuitization will reduce the death benefit in the same proportion that the Accumulated Value was reduced on the date of the partial Surrender or partial Annuitization. The adjustment for partial Surrenders is equal to (1 divided by 2) multiplied by 3, where:

1.Is the amount of the partial Surrender (and any applicable Surrender Charges and fees) or the amount of the partial Annuitization; and

2.Is the Accumulated Value immediately prior to the partial Surrender or partial Annuitization; and

3.Is the total Premium Payment adjusted for prior partial Surrenders and partial Annuitizations immediately prior to the current partial Surrender or partial Annuitization.

ANNUITIZATION BENEFIT

ANNUITY BENEFIT PAYMENTS

An annuity benefit payment is a periodic income payable to You. If this contract is in force and the Annuitant is living, an annuity benefit payment becomes payable upon the earlier of the date You request payments begin or the Annuitization Date.

You may apply all or a portion of the Accumulated Value, adjusted for the Bond Adjustment, to an annuity benefit payment option at any time after the second Contract Anniversary and prior to the Annuitization Date by sending Us Notice at Our office. Contract values applied to an annuity benefit payment option will be based on the Accumulated Value, adjusted for the Bond Adjustment, as of the date We receive the Notice in Good Order, and such application will reduce Your Accumulated Value accordingly. We reserve the right to limit the number of partial Annuitizations that may be requested in a Contract Year, but it will never be less than one per Contract Year.

If the entire Accumulated Value is applied to an annuity benefit payment option, this contract will terminate.

ANNUITY BENEFIT PAYMENT OPTION ELECTION

Prior to the Annuitization Date, You may elect an annuity benefit payment option from the Description of Annuity Benefit Payment Options provision below. If You do not elect an annuity benefit payment option, We will make annuity benefit payments on the following basis:

1.For contracts with one Annuitant, annuity benefit payments will be based on a life income with 10-year guaranteed period.

2.For contracts with Joint Annuitants, annuity benefit payments will be based on a joint and 100% survivor life income with 10-year guaranteed period.

CONDITIONS

Election of any annuity benefit payment option is subject to the following conditions:

1.No changes may be made to an annuity benefit payment option once a supplementary contract is issued.

2.If the amount applied to an annuity benefit payment option results in an annuity benefit payment that is less than $25.00, We reserve the right to change the frequency of Your annuity benefit payments to an interval that will result in an annuity benefit payment of at least $25.00.

3.If an annuity benefit payment option is chosen for the payment of the death benefit, the annuity benefit payment options available are limited to those that comply with all applicable laws, including, particularly, IRC section 72(s), as may be amended from time to time.

4.We reserve the right to require evidence of the Annuitant's Age, gender if applicable, and continuing survival.

DESCRIPTION OF ANNUITY BENEFIT PAYMENT OPTIONS

OPTION A, CUSTOM: A custom benefit arrangement can be designed with Our written approval.

OPTION B, LIFE INCOME: We will make annuity benefit payments during the Annuitant’s lifetime. Annuity benefit payments cease when the Annuitant dies.

OPTION C, LIFE INCOME WITH GUARANTEED PERIOD: We will make annuity benefit payments for the longer of the Annuitant’s lifetime or a guaranteed period that You select. If the Annuitant dies after annuity benefit payments begin but before the end of the guaranteed period, the remaining annuity benefit payments will be paid under the annuity benefit payment option.

OPTION D, JOINT AND SURVIVOR LIFE INCOME: We will make annuity benefit payments during the lifetime of the Joint Annuitants. Annuity benefit payments cease when both Annuitants have died.

OPTION E, JOINT AND SURVIVOR LIFE INCOME WITH GUARANTEED PERIOD: We will make annuity benefit

If both Annuitants die after annuity benefit payments begin but before the end of the guaranteed period, the remaining annuity benefit payments will be paid under the annuity benefit payment option.

OPTIONS B, C, D AND E: The purchase rates for these annuity benefit payment options are based on the 2012 Individual Annuity Mortality Period Life Table with full generation mortality projection using Projection Scale G2 and 0.25% interest. Annuity benefit payments will be in an amount We determine but not less than those guaranteed under this section by applying the accumulated value to an annuity benefit payment option with purchase rates noted herein. Annuity benefit payment options are also based on the gender of the Annuitant or Joint Annuitant, if applicable, except for contracts issued in states that require unisex mortality or in connection with employment related annuities and benefit plans not based on the gender of the Annuitant. In these instances, the mortality rates used will be 100% female.

FEES AND CHARGES

The following contract fees and charges are shown on the Data Page.

TRANSACTION FEE

We reserve the right to charge the Transaction Fee for each unscheduled partial surrender after the 12th unscheduled partial surrender in each Contract Year or for unscheduled transfers. The Transaction Fee will be deducted proportionately from the Segment Options from which the amount is surrendered.

SURRENDER CHARGE

If any Surrender amount requested is greater than the Free Surrender Amount, then the Surrender Charge is calculated as follows:

(Surrender amount requested – any remaining Free Surrender Amount) x Surrender Charge percentage. For a full Surrender, any Surrender Charge will be deducted from the Accumulated Value.

For a partial Surrender, the Surrender Charge will be deducted pro-rata from the Segment Options from which the amount is surrendered.

Surrender Charges will not apply when:

1.You Surrender an amount up to the Free Surrender Amount;

2.You take a partial Surrender up to the IRC required minimum distribution amount for this contract;

3.all or a portion of the Accumulated Value is applied to an annuity benefit payment option; or

4.the death benefit is distributed.

GENERAL INFORMATION

TERMINATION

This contract will terminate when one of the following occurs:

1.the Accumulated Value is applied under an annuity benefit payment option;

2.the contract is surrendered in full; or

3.the death benefit is paid to the beneficiary(ies).

If the Accumulated Value or total Premium Payment (less partial Surrender and applicable Surrender Charges) is less than $2,000, We reserve the right to terminate this Contract and pay You the Accumulated Value, less any applicable charges, in one lump sum payment.

This right will not be exercised in an unfairly discriminatory manner.

DEFERMENT OF PAYMENTS AND TRANSFERS

We reserve the right to defer payments and transfers for any period during which the NYSE is closed for trading (except for normal holiday closing) or when the Securities and Exchange Commission has determined that a state of emergency exists that may make determination and payment impractical.

OWNERSHIP

The Owner and Joint Owner, if any, on the Contract Date are shown on the Data Page. As Owner(s), You may exercise every right and enjoy every privilege provided by Your contract, subject to the rights of any irrevocable beneficiary(ies). These rights and privileges continue while Your contract is in force. If Joint Owners are named, both must consent to any exercise of these rights.

BENEFICIARY

Upon receipt of the Notice, including due proof of death, the beneficiary(ies) named and recorded at Our office will receive the death benefit. You can change the beneficiary designation as provided below. Subject to any applicable laws and requirements, if the only primary beneficiary is the Owner’s surviving spouse, the Contract may be continued upon the death of the Owner with the spouse as the new Owner.

When the death benefit becomes payable, and a beneficiary has not survived the Owner, We will pay the death benefit to any surviving beneficiary(ies) according to the percentages You designated. If no beneficiary(ies) survives the Owner, the death benefit will be paid to the Owner's estate unless otherwise specified.

We will not be responsible for the validity or sufficiency of any allowable assignment and an assignment must be consented to by all irrevocable beneficiaries, if any. An assignment as collateral does not change the Owner. Your rights and any beneficiary’s interest will be subject to the assignment.

SEGMENT LOCK-IN RIDER

This rider is part of Your contract. All definitions, provisions, and exceptions of the contract apply to this rider unless specifically changed by this rider. The rider effective date is the same as the Contract Date unless a different rider effective date is shown on the Data Page. In the event of a conflict between any provision in this rider and the contract, the provisions of this rider will control.

RIDER BENEFIT

This rider gives You the ability to lock-in the then current Equity Adjustment for a Segment Option prior to the end of a Segment Term.

DEFINITIONS

EQUITY ADJUSTMENT is the adjustment (which could be positive, negative, or equal to zero) to the Accumulated Value expressed as a percentage, based on the change in the fair value of the hypothetical derivative assets designed to replicate credits provided by a Segment Option at the end of a Segment Term.

LOCK-IN DATE is the Valuation Day that We receive Notice for a lock-in or the Valuation Day the Equity Adjustment crosses a Lock-In Threshold.

LOCK-IN THRESHOLD(S) is a percentage(s) You can set at which a lock-in will automatically occur.

SEGMENT LOCK-IN

You can request a Segment Lock-In or set Lock-In Threshold(s) on any Valuation Day. In order to request a Segment Lock-In or set Lock-In Threshold(s) You must provide Us with Notice. The Lock-In Date will be the Valuation Day We receive Notice in Good Order to lock the Segment Option, or the Valuation Day where the Equity Adjustment crosses a Lock-In Threshold. The Equity Adjustment is locked in on the Lock-In Date and may be different than the prior Valuation Day’s Equity Adjustment as well as the Lock-In Threshold that was set.

You can set an upper threshold and/or lower threshold per Segment Option. An upper threshold is a threshold that is above the current Equity Adjustment and a lower threshold is a threshold that is below the current Equity Adjustment. Lock-In Threshold(s) may be removed or changed if You provide Us with Notice in Good Order as long as a Segment Lock-In has not happened on the specified Segment Option yet.

Once a Segment Lock-In occurs, it is irrevocable for that Segment Term. A Segment Lock-In may not be applied retroactively and can only be exercised for the entire Segment Option. A Segment Lock-In may only be exercised once per Segment Term for each Segment Option. When a Segment Lock-In has been exercised, the Segment Term will end on the next Segment Anniversary which will also be the Segment End Date. Once the Segment Option has been locked the Equity Adjustment will not change until the Segment Term is complete. The Equity Adjustment on the Lock-In Date will be the Segment Return that will be used in the calculation of the Segment Credit, which will be applied on the Segment End Date.

If you exercise a Segment Lock-In; the Segment Credit You receive may be different than the Segment Credit You would have received on the Segment End Date if You hadn’t exercised the Segment Lock-In. You may receive less than the full protection of the Buffer Rate or Floor Rate.

At the Segment End Date on or after the Lock-In Date, the lock will end and We will reallocate the Accumulated Value per Your instructions. If You have not provided new allocation instructions, We will reallocate the Accumulated Value as stated in Your contract. You may exercise the Segment Lock-In again during the next Segment Term. We reserve the right to limit the availability of the Segment Lock-In rider for certain Segment Options.
