SHAREHOLDER SERVICES AGREEMENT

THIS SHAREHOLDER SERVICES AGREEMENT is made and entered into as of April 1, 1999 by and between THE PRINCIPAL LIFE INSURANCE COMPANY (the “Company”), and AMERICAN CENTURY INVESTMENT MANAGEMENT, INC. (“ACIM”).

WHEREAS, the Company offers to the public certain group and individual variable annuity and variable life insurance contracts (the “Contracts”); and

WHEREAS, the Company wishes to make available as investment options under the Contracts VP Balanced, VP Capital Appreciation, VP Income & Growth, VP International and VP Value (the “Funds”), each of which is a series of mutual fund shares registered under the Investment Company Act of 1940, as amended, and issued by American Century Variable Portfolios, Inc. (the “Issuer”); and

WHEREAS, on the terms and conditions hereinafter set forth, ACIM desires to make shares of the Funds available as investment options under the Contracts and to retain the Company to perform certain administrative services on behalf of the Funds, and the Company is willing and able to furnish such services;

NOW, THEREFORE, the Company and ACIM agree as follows:

1. Transactions in the Funds. Subject to the terms and conditions of this Agreement, ACIM will cause the Issuer to make shares of the Funds available to be purchased, exchanged, or redeemed, by or on behalf of the Account (defined in Section 7(a) below) through a single account per Fund at the net asset value applicable to each order. The Funds’ shares shall be purchased and redeemed on a net basis in such quantity and at such time as determined by the Company to satisfy the requirements of the Contracts for which the Funds serve as underlying investment media. Dividends and capital gains distributions will be automatically reinvested in full and fractional shares of the Funds.

2. Administrative Services. The Company agrees to provide all administrative services for the Contract owners, including but not limited to those services specified in EXHIBIT A (the “Administrative Services”). Neither ACIM nor the Issuer shall be required to provide Administrative Services for the benefit of Contract owners. The Company agrees that it will maintain and preserve all records as required by law to be maintained and preserved in connection with providing the Administrative Services, and will otherwise comply with all laws, rules and regulations applicable to the marketing of the Contracts and the provision of the Administrative Services.

Contract # AME-06079-1999-04-01-IND

3. Timing of Transactions. ACIM hereby appoints the Company as agent for the Funds for the limited purpose of accepting purchase and redemption orders for Fund shares from the Contract owners. On each day the New York Stock Exchange (the “Exchange”) is open for business (each, a “Business Day”), the Company may receive instructions from the Contract owners for the purchase or redemption of shares of the Funds (“Orders”). Orders received and accepted by the Company prior to the close of regular trading on the Exchange (the “Close of Trading”) on any given Business Day (currently, 4: 00 p.m. Eastern time) and transmitted to the Funds’ transfer agent by 9: 30 a.m. Eastern time on the next Business Day will be executed at the net asset value determined as of the Close of Trading on the immediately prior Business Day. Any Orders received by the Company on such day but after the Close of Trading, and all Orders that are transmitted to the Funds’ transfer agent after 9: 30 a.m. Eastern time on the next Business Day, will be executed at the net asset value determined as of the Close of Trading on the next Business Day following the day of receipt of such Order by the Funds’ transfer agent. The day as of which an Order is executed by the Funds’ transfer agent pursuant to the provisions set forth above is referred to herein as the ‘Trade Date”.

4. Processing of Transactions.

(a) If transactions in Fund shares are to be settled through the National Securities Clearing Corporation’s Mutual Fund Settlement, Entry, and Registration Verification (Fund/SERV) system, the terms of the FUND/SERV AGREEMENT, between Company and American Century Services Corporation, shall apply.

(b) If transactions in Fund shares are to be settled directly with the Funds’ transfer agent, the following provisions shall apply:

(1) By 6:30 p.m. Eastern time on each Business Day, ACIM (or one of its affiliates) will provide to the Company via direct electronic transmission acceptable to the Company, or if such transmission is unavailable for any reason, via facsimile, the Funds’ net asset value, dividend and capital gain information and, in the case of income funds, the daily accrual for interest rate factor (mil rate), determined at the Close of Trading. In the event any adjustment is required to correct any error in the computation of the net asset value of a Fund’s shares at the shareholder level as a result of a pricing error that is deemed to be material under the pricing policy of the Fund’s Board of Directors or which ACIM otherwise deems necessary to correct at the Account level, ACIM and the Company shall work together to correct the Accounts. ACIM shall reimburse the Company its reasonable out-of-pocket expenses, not including overtime wages, incurred in correcting the Accounts.

(2) By 9:30 a.m. Eastern time on each Business Day, the Company will provide to ACIM via direct electronic transmission acceptable to ACIM, or if such transmission is unavailable for any reason, via facsimile a report stating whether the instructions received by the

Company from Contract owners by the Close of Trading on the prior Business Day resulted in the Account being a net purchaser or net seller of shares of the Funds.

(3) Upon the timely receipt from the Company of the report described in (2) above, the Funds’ transfer agent will execute the purchase or redemption transactions (as the case may be) at the net asset value computed as of the Close of Trading on the Trade Date. Payment for net purchase transactions shall be made by wire transfer to the applicable Fund custodial account designated by the Funds on the Business Day next following the Trade Date. Such wire transfers shall be initiated by the Company’s bank prior to 4:00 p.m. Eastern time and received by the Funds prior to 6:00 p.m. Eastern time on the Business Day next following the Trade Date (“T+1”). If payment for a purchase Order is not timely received, such Order will be executed at the net asset value next computed following receipt of payment. Payments for net redemption transactions shall be made by wire transfer by the Issuer to the account(s) designated by the Company on T+l; provided, however, the Issuer reserves the right to settle redemption transactions within the time period set forth in the applicable Fund’s then-current prospectus. On any Business Day when the Federal Reserve Wire Transfer System is closed, all communication and processing rules will be suspended for the settlement of Orders. Orders will be settled on the next Business Day on which the Federal Reserve Wire Transfer System is open and the original Trade Date will apply.

5. Prospectus and Proxy Materials.

(a) ACIM shall provide the Company with copies of the Issuer’s proxy materials, periodic fund reports to shareholders and other materials that are required by law to be sent to the Issuer’s shareholders. In addition, ACIM shall provide the Company with a sufficient quantity of prospectuses of the Funds to be used in conjunction with the transactions contemplated by this Agreement, together with such additional copies of the Issuer’s prospectuses as may be reasonably requested by Company. If the Company provides for pass-through voting by the Contract owners, or if the Company determines that pass-through voting is required by law, ACIM will provide the Company with a sufficient quantity of proxy materials for each, as directed by the Company.

(b) The cost of preparing, printing and shipping of the prospectuses, proxy materials, periodic fund reports and other materials of the Issuer to the Company shall be paid by ACIM or its agents or affiliates; provided, however, that if at any time ACIM or its agent reasonably deems the usage by the Company of such items to be excessive, it may, prior to the delivery of any quantity of materials in excess of what is deemed reasonable, request that the Company demonstrate the reasonableness of such usage. If ACIM believes the reasonableness of such usage has not been adequately demonstrated, it may request that the party responsible for such excess usage pay the cost of printing (including press time) and delivery of any excess copies of such materials. Unless the Company agrees to make such payments, ACIM may refuse to supply such additional materials and ACIM shall be deemed in compliance with this Section 5 if it delivers to the Company at least the number of prospectuses and other materials as may be required by the Issuer under applicable law.

(c) The cost of any distribution of prospectuses, proxy materials, periodic fund reports and other materials of the Issuer to the Contract owners shall be paid by the Company and shall not be the responsibility of ACIM or the Issuer.

6. Compensation and Expenses.

(a) The Account shall be the sole shareholder of Fund shares purchased for the Contract owners pursuant to this Agreement (the “Record Owner”). The Record Owner shall properly complete any applications or other forms required by ACIM or the Issuer from time to time.

(b) ACIM acknowledges that it will derive a substantial savings in administrative expenses, such as a reduction in expenses related to postage, shareholder communications and recordkeeping, by virtue of having a single shareholder account per Fund for the Account rather than having each Contract owner as a shareholder. In consideration of the Administrative Services and performance of all other obligations under this Agreement by the Company, ACIM will pay the Company a fee (the “Administrative Services Fee”) equal to 25 basis points (0. 25%) per annum of the average aggregate amount invested by the Company under this Agreement.

(c) The payments received by the Company under this Agreement are for administrative and shareholder services only and do not constitute payment in any manner for investment advisory services or for costs of distribution.

(d) For the purposes of computing the payment to the Company contemplated by this Section 6, the average aggregate amount invested by the Company on behalf of the Account in the Funds over a one month period shall be computed by totaling the Company’s aggregate investment (share net asset value multiplied by total number of shares of the Funds held by the Company) on each Business Day during the month and dividing by the total number of Business Days during such month.

(e) ACIM will calculate the amount of the payment to be made pursuant to this Section 6 at the end of each calendar quarter and will make such payment to the Company within 30 days thereafter. The check for such payment will be accompanied by a statement showing the calculation of the amounts being paid by ACIM for the relevant months and such other supporting data as may be reasonably requested by the Company and shall be mailed to:

12. Potential Conflicts

(a) The Company has received a copy of an application for exceptive relief, as amended, filed by the Issuer on December 21, 1987, with the SEC and the order issued by the SEC in response thereto (the “Shared Funding Exemptive Order”). The Company has reviewed the conditions to the requested relief set forth in such application for exemtive relief. As set forth in such application, the Board of Directors of the Issuer (the “Board”) will monitor the Issuer for the existence of any material irreconcilable conflict between the interests of the contract owners of all separate accounts (“Participating Companies”) investing in funds of the Issuer. An irreconcilable material conflict may arise for a variety of reasons, including: (i) an action by any state insurance regulatory authority; (ii) a change in applicable federal or state insurance, tax, or securities laws or regulations, or a public ruling, private letter ruling, no-action or interpretative letter, or any similar actions by insurance, tax or securities regulatory authorities; (iii) an administrative or judicial decision in any relevant proceeding; (iv) the manner in which the investments of any portfolio are being managed; (v) a difference in voting instructions given by variable annuity contract owners and variable life insurance contract owners; or (vi) a decision by an insurer to disregard the voting instructions of contract owners. The Board shall promptly inform the Company if it determines that an irreconcilable material conflict exists and the implications thereof.

(b) The Company will report any potential or existing conflicts of which it is aware to the Board. The Company will assist the Board in carrying out its responsibilities under the Shared

Funding Exemptive Order by providing the Board with all information reasonably necessary for the Board to consider any issues raised. This includes, but is not limited to, an obligation by the Company to inform the Board whenever contract owner voting instructions are disregarded.

(c) If a majority of the Board, or a majority of its disinterested Board members, determines that a material irreconcilable conflict exists with regard to contract owner investments in a Fund, the Board shall give prompt notice to all Participating Companies. If the Board determines that the Company is responsible for causing or creating said conflict, the Company shall at its sole cost and expense, and to the extent reasonably practicable (as determined by a majority of the disinterested Board members), take such action as is necessary to remedy or eliminate the irreconcilable material conflict. Such necessary action may include but shall not be limited to:

	(i)		withdrawing the assets allocable to the Account from the Fund and reinvesting such assets in a different investment medium or submitting the question of whether such segregation should be implemented to a vote of all affected contract owners and as appropriate, segregating the assets of any appropriate group (i.e., annuity contract owners, life insurance contract owners, or variable contract owners of one or more Participating Companies) that votes in favor of such segregation, or offering to the affected contract owners the option of making such a change; and/or

	(ii)		establishing a new registered management investment company or managed separate account.

(d) If a material irreconcilable conflict arises as a result of a decision by the Company to disregard its contract owner voting instructions and said decision represents a minority position or would preclude a majority vote by all of its contract owners having an interest in the Issuer, the Company at its sole cost, may be required, at the Board’s election, to withdraw an Account’s investment in the Issuer and terminate this Agreement; provided, however, that such withdrawal and termination shall be limited to the extent required by the foregoing material irreconcilable conflict as determined by a majority of the disinterested members of the Board.

(e) For the purpose of this Section 12, a majority of the disinterested Board members shall determine whether or not any proposed action adequately remedies any irreconcilable material conflict, but in no event will the Issuer be required to establish a new funding medium for any Contract. The Company shall not be required by this Section 12 to establish a new funding medium for any Contract if an offer to do so has been declined by vote of a majority of the Contract owners materially adversely affected by the irreconcilable material conflict.

13. Termination; Withdrawal of Offering. This Agreement may be terminated by either party upon 180 days’ prior written notice to the other parties. Notwithstanding the above, the Issuer reserves the right, without prior notice, to suspend sales of shares of any Fund, in whole or in

part, or to make a limited offering of shares of any of the Funds in the event that (A) any regulatory body commences formal proceedings against the Company, ACIM, affiliates of ACIM, or the Issuer, which proceedings ACIM reasonably believes may have a material adverse impact on the ability of ACIM, the Issuer or the Company to perform its obligations under this Agreement or (B) in the judgment of ACIM, declining to accept any additional instructions for the purchase or sale of shares of any such Fund is warranted by market, economic or political conditions. Notwithstanding the foregoing, this Agreement may be terminated immediately (i) by any party as a result of any other breach of this Agreement by another party, which breach is not cured within 30 days after receipt of notice from the other party, or (ii) by any party upon a determination that continuing to perform under this Agreement would, in the reasonable opinion of the terminating party’s counsel, violate any applicable federal or state law, rule, regulation or judicial order. Termination of this Agreement shall not affect the obligations of the parties to make payments under Section 4 for Orders received by the Company prior to such termination and shall not affect the Issuer’s obligation to maintain the Account as set forth by this Agreement. Following termination, ACIM shall not have any Administrative Services payment obligation to the Company (except for payment obligations accrued but not yet paid as of the termination date).

14. Non-Exclusivity. Each of the parties acknowledges and agrees that this Agreement and the arrangement described herein are intended to be non-exclusive and that each of the parties is free to enter into similar agreements and arrangements with other entities.

15. Survival. The provisions of Section 9 (use of names) and Section 11 (indemnity) of this Agreement shall survive termination of this Agreement.

16. Amendment Neither this Agreement, nor any provision hereof, may be amended, waived, discharged or terminated orally, but only by an instrument in writing signed by all of the parties hereto.

17. Notices. All notices and other communications hereunder shall be given or made in writing and shall be delivered personally, or sent by telex, telecopier, express delivery or registered or certified mail, postage prepaid, return receipt requested, to the party or parties to whom they are directed at the following addresses, or at such other addresses as may be designated by notice from such party to all other parties.
