In administering Subsection 10.03(B) of the Defined Contribution Prototype Plan and Trust, the following additional provision shall apply: Notwithstanding the authority of the Trustee to give proxies as specified in Subsection 10.03(B)(g), each Participant and beneficiary in the Plan who has a beneficial interest in the Employer Stock Fund shall be entitled to direct the Trustee as to the manner in which the Employer stock having voting rights which are allocated to such Participant's or beneficiary's account shall be voted. The Trustee, itself or by its nominee, shall vote said stock as follows: (i) the Employer shall adopt reasonable measures to notify said Participants and beneficiaries of the date and purpose of each meeting of stockholders of the Employer at which holders of shares of stock shall be entitled to vote, and to request instructions from such Participants and beneficiaries to the Employer, its agent or the Trustee as to the voting at such meeting of the number of shares of common stock (including fractional shares) in the account of each such Participant or beneficiary, whether or not vested; (ii) in each case the Trustee, itself or by proxy, shall vote the shares of said stock (including fractional shares) in the account of each such Participant or beneficiary in accordance with the directions of the Participant or beneficiary as communicated directly to the Trustee or to the Trustee by the Employer or its agent; (iii) if prior to the time of such meeting of stockholders (or a date prior thereto specified by the Trustee), the Trustee shall not have received timely directions from a Participant or beneficiary, or from the Employer as to the manner of voting any shares of allocated stock in the account of such Participant or beneficiary, the Trustee shall vote, itself or by proxy, all such shares of common stock in all matters coming before the meeting, in the same ratio, to the nearest whole vote, as the ratio in which the total shares with respect to which timely directions were received were voted in such matters. 9. Item 29 of the Adoption Agreement to the Plan is hereby amended by adding the following thereto: All accounts shall be invested as directed by Participants in such investment alternatives as are selected by the Plan Administrator. If an election has not been made by a Participant, then all accounts of such Participant shall be invested in the Farm Bureau group annuity investment option. 10. In administering Subsection 10.03(F) of the Defined Contribution Prototype Plan and Trust, the following additional provisions shall apply: If so directed, the Trustee is authorized to invest in Qualifying Employer securities in amounts that may exceed 10% of the value of Plan assets, up to 100% of the value of Plan assets, to be held in an Employer Stock Fund. Such investment shall be at the direction of the 46 Named Fiduciary, or if authorized by the Named Fiduciary, by an Investment Manager or as directed by Participants or beneficiaries. Notwithstanding such direction, in the event that a tender or exchange offer is made for all or any portion of the Employer's common stock held in the Fund, the Employer shall take such action as is practicable to provide each Participant or beneficiary of the Plan having an interest in such Fund with the same information that is distributed by the Employer to the stockholders of the Employer owning the same class of common stock for which such offer is made. Notwithstanding any other provision of the Plan, in the event such an offer is made, each such Participant or beneficiary shall have the right to direct the Trustee, by timely notice, to tender or exchange all or any portion of the full shares of such common stock credited to his account which are at such time fully vested, and the Trustee shall so tender or exchange only upon receipt of such direction. All property received in the form of cash in exchange for such common stock so tendered shall, upon receipt, be transferred out of the Employer Stock Fund and shall be invested by the Trustee in accordance with the investment direction then on file with the Trustee for investment of deferral contributions with respect to each affected Participant. If such investment direction directs any funds to be invested in the Employer Stock Fund, such amount shall instead be invested in the Farm Bureau group annuity contract issued to the Plan. All property received other than cash in exchange for such common stock so tendered shall, upon receipt be held by the Trustee in the Employer Stock Fund within the accounts of those Participants who so tendered. Notwithstanding any other provision of this Plan, such property other than cash may be held within such Fund and shall be administered, invested, reinvested and distributed in accordance with the applicable terms of this Plan. 11. All Regular and Qualifying Matching Contributions shall be invested by the Trustee in FBL Financial Group, Inc. common stock. A Participant shall have the same investment choices for that account as he does for his other accounts in the Plan, and he may transfer out of the Employer Stock Fund with respect to his matching account into other investment choices at any time. 12. The Defined Contribution Prototype Plan and Trust is amended by adding the following language to Section 10.03(B)(c) of that document: The Trustee is authorized to invest and reinvest all or any part of the principal and income of the Trust through any common or collective trust fund or pooled investment fund maintained by the Trustee for the collective investment of funds held by it in a fiduciary capacity. The provisions of the document governing any such common or collective trust fund as it may be amended from time to time shall govern any investment therein and are hereby made a part of this Defined Contribution Prototype Plan and Trust. 47 IOWA FARM BUREAU FEDERATION, Plan Sponsor By: /s/ Jerry C.
