(2) Matching Contributions shall be made each pay period to the Matching Account of each Participant who has made Pretax Contributions during the pay period. (c) Profit-Sharing Contributions. Each Employer may elect to make a Profit-Sharing Contribution to be allocated among its Qualified Participants in such amount as its board of directors may determine. (d) Interim Benefit Supplement. Each Plan Year, each Employer shall contribute, on behalf of each Qualified Participant who was an active participant (as of December 31, 1995) in a defined benefit plan described in Appendix B, an amount equal to the Supplemental Percentage multiplied by the Participant's Compensation. The Interim Benefit Supplement payable to any Participant's Supplemental Account during the Plan Year 6 shall be reduced by the Profit-Sharing Contribution (if any) which is allocable to that Participant's Profit-Sharing Account for the Plan Year. This contribution shall be made as of the end of each Plan Year. 25. The first sentence of Section 3.06(a) is amended in its entirety to read as follows: "(a) The maximum Pretax Contribution a Participant may make in a calendar year (when combined with any other such contributions made to any other plan containing a cash or deferred arrangement sponsored by an Employer or Affiliated Company) is specified in Code section 402(g)(1)." 26. Effective January 1, 1997, Section 3.06(b) is amended in its entirety to read as follows: "(b) As of the end of a Plan Year (or more frequently, if determined by the Committee), the Committee shall determine if the limitations imposed by this Article 3 are sufficient or if contributions must be forfeited, distributed, or allocated to a suspense account, in the order provided below: (1) First, the Committee shall determine if Pretax Contributions in excess of the Code section 402(g)(1) limit have been made to the Plan. If so, the excess deferral shall be returned to the Participant who made it. The Committee shall endeavor to make a correcting distribution by the April 15 following the year in which such excess deferral was made. (2) Second, the Committee shall determine whether the actual deferral percentage ("ADP") test set forth in Treas. Reg. section 1.401(k)- 1(b) (the "ADP Test") has been met for the Plan Year. If not, the Committee shall reduce the Pretax Contributions made on behalf of Highly Compensated Participants, beginning with such Participant with the highest amount of Pretax Contributions for such Plan Year until such contributions equal the greater of (i) the largest amount such that the ADP Test shall be satisfied and (ii) the next highest amount of Pretax Contributions made for such Plan Year by any other Highly Compensated Participant. If further reductions are necessary, then such Pretax Contributions made on behalf of each Highly Compensated Participant with the highest amount of Pretax Contributions for such Plan Year (determined after the reduction described in the preceding sentence) shall be reduced in accordance with the preceding sentence. Such reductions shall continue to be made until the ADP Test is satisfied. (3) Third, the Committee shall determine whether the actual contribution percentage ("ACP") test in Reg. section 1.401(m)-1(b) (the "ACP Test") has been met for the Plan Year. If not, the Committee shall reduce the Matching Contributions made on behalf of Highly Compensated Participants, beginning with such 7 Participant with the highest amount of Matching Contributions for such Plan Year until such contributions equal the greater of (i) the largest amount such that the ACP Test shall be satisfied and (ii) the next highest amount of Matching Contributions made for such Plan Year on behalf of any other Highly Compensated Participant. If further reductions are necessary, then Matching Contributions made on behalf of each Highly Compensated Participant with the highest amount of Matching Contributions for such Plan Year (determined after the reduction described in the preceding sentence) shall be reduced in accordance with the preceding sentence. Such reductions shall continue to be made until the ACP Test is satisfied. (4) Fourth, the Committee shall determine whether the multiple use test ("MUT") in Reg. section 1.401(m)-2(b) is met for the Plan Year. If not, the Committee shall reduce the actual contribution percentage for Highly Compensated Participants, in accordance with Section 3.06(b)(4). (5) Fifth, the Committee shall determine whether contributions to the Plan have been made which exceed the limitations of Code sections 415(c) and (e). The Committee shall use W-2 compensation (as defined in Reg. section 1.415-2(d)(11)(i)) in making this determination. If, as a result of the allocation of forfeitures, a reasonable error in determining the Participant's W-2 compensation, or a reasonable error in determining the Participant's maximum Pretax Contributions, the annual addition to a Participant's Account exceeds the maximum permitted, such excess annual addition shall be distributed from the Participant's Pretax Account. (6) Sixth, any Matching Contribution made on behalf of a Participant, based on a Pretax Contribution returned to the Participant and not distributed or forfeited in accordance with Section 3.06(b)(4), shall be forfeited and applied to reduce Employer contributions under the Plan. The Committee shall distribute any excess Pretax Contributions to each Participant. The Committee shall also distribute to each vested Participant the portion of the reductions applicable to the excess Matching Contributions related thereto. Any excess Matching Contributions made on behalf of non-vested Participants shall be forfeited. All distributions to Participants pursuant to this paragraph (b) shall be adjusted for any earnings, gains or losses allocable to such amounts and shall be made no later than the last day of the subsequent Plan Year for which such adjustment is made. The amount of reductions distributed to a Participant pursuant to subsection (3) shall be reduced by any Pretax Contributions previously distributed to such Participant pursuant to paragraph (1) in order to comply with the limitations of Section 402(g) of the Code. The unadjusted amount of any reductions so distributed shall be treated as an annual addition for purposes of paragraph (2). 27. Section 3.07 is amended to read as follows: 8 "3.07. REEMPLOYMENT OF VETERANS. The provisions of this Section shall apply in the case of the reemployment by an Employer of an Eligible Employee, within the period prescribed by USERRA, after the Employee's completion of a period of qualified military service (as defined in Code Section 414(u)(5)). The provisions of this Section are intended to comply with the requirements of USERRA and Section 414(u) of the Code, and shall be interpreted in accordance with such intent. (a) MAKE UP OF CORE CONTRIBUTIONS, PROFIT SHARING CONTRIBUTIONS AND INTERIM BENEFIT SUPPLEMENT. Such Employee shall receive the Core and Profit Sharing Contributions and the Interim Benefit Supplement, if any, which the Employee would have received if the Employee had continued in employment with his Employer during such period of qualified military service. Such Employee shall be deemed to have earned "Compensation" from his Employer during such period of qualified military service for this purpose in the amount prescribed by Code Sections 414(u)(2)(B) and 414(u)(7). (b) MAKE UP OF PRETAX CONTRIBUTIONS. Such Employee shall have the right to make contributions under the Plan ("Make Up Deferrals"), in addition to any Pretax Contributions which the Employee elects to have made under the Plan pursuant to Section 3.01. From time to time while employed by an Employer, such Employee may elect to make such Make Up Deferrals during the period beginning on the date of such Employee's reemployment and ending on the earlier of: (i) the end of the period equal to the product of three and such Employee's period of qualified military service, and (ii) the fifth anniversary of the date of such reemployment. Such Employee shall not be permitted to contribute Make Up Deferrals to the Plan in excess of the amount which the Employee could have elected to have made under the Plan in the form of Pretax Contributions if the Employee had continued in employment with his Employer during such period of qualified military service. Such Employee shall be deemed to have earned "Compensation" from his Employer during such period of qualified military service for this purpose in the amount prescribed by Code Sections 414(u)(2)(B) and 414(u)(7). The manner in which an Eligible Employee may elect to Make Up Deferrals pursuant to this subsection (b) shall be prescribed by the Committee. 9 (c) MAKE UP OF MATCHING CONTRIBUTIONS. An Eligible Employee who makes Make Up Deferrals as described in subsection (b) shall be entitled to an allocation of matching contributions ("Make Up Matching Contributions") in an amount equal to the amount of Matching Contributions which would have been allocated to the Account of such Eligible Employee under the Plan if such Make Up Deferrals had been made in the form of Pretax Contributions during the period of such Employee's qualified military service (as determined pursuant to Code Section 414(u)). The amounts necessary to make such allocation of Make Up Matching Contributions shall be derived from Forfeitures not yet applied towards Matching Contributions for the Plan Year in which the Make Up Deferrals are made, and if such Forfeitures are not sufficient for this purpose, then the Eligible Employee's Employer shall make a special contribution which shall be utilized solely for purposes of such allocation. Any contributions made by an Eligible Employee or an Employer pursuant to this Section on account of a period of qualified military service in a prior Plan Year shall not be subject to the limitations prescribed by Sections 3.04 and 3.06 of the Plan (relating to Sections 402(g) and 415 of the Code) for the Plan Year in which such contributions are made. The Plan shall not be treated as failing to satisfy the nondiscrimination rules of Section 3.06 of the Plan (relating to Sections 401(k)(3) and 401(m) of the Code) for any Plan Year solely on account of any make up contributions made by an Eligible Employee or an Employer pursuant to this Section." 28.

After termination of employment, the remainder of the Participant's Account shall be paid in accordance with Section 6.04(a)." 33.

Any Employer and certain unrelated companies (as provided in Section 14.03) may adopt the Plan for the benefit of their Employees as of a date specified. No such adoption shall be effective until such adoption has been approved by the Committee. Notwithstanding any term or provision of the Plan to the contrary (including, but not limited to, terms and conditions concerning Service, Compensation and amount of retirement benefits), the terms and provisions as may be imposed with respect to such Employer and its Employees in an applicable supplement or appendix to the Plan shall govern. Any Employer who adopts the Plan in accordance with this Section or Section 14.03 13 agrees to be bound by all the terms, provisions, conditions and limitations of the Plan and the accompanying Trust Agreement which are pertinent to any entity defined as an "Employer" in the Plan with respect to its Eligible Employees under the Plan. Such Employer further agrees that the Committee shall act for the Employer and its Eligible Employees under the provisions of the Plan. Such Employer further agrees to furnish from time to time such information with reference to its Eligible Employees as may be required by the Committee. 14.02 PROCEDURE FOR WITHDRAWAL. Any Employer (other than the Company) may, subject to such conditions as may be imposed by the Company, terminate its adoption of the Plan. Upon discontinuance of an Employer's participation in the Plan, the Trustee shall cause a determination to be made of the equitable part of the Plan assets held on account of Participants of the withdrawing Employer and their Beneficiaries. The Committee shall direct the Trustee to transfer assets representing such equitable part to a separate fund for the plan of the withdrawing Employer. Such withdrawing Employer may thereafter exercise, in respect of such separate fund, all the rights and powers reserved to the Company with respect to Plan assets. The plan of the withdrawing Employer shall, until amended by the withdrawing Employer, continue with the same terms as the Plan herein, except that with respect to the separate plan of the withdrawing Employer the words "Employer," "Employers," and "Company" shall thereafter be considered to refer only to the withdrawing Employer. Any discontinuance of participation by an Employer shall be effected in such manner that each Participant or Beneficiary would (if the Plan and the plan of the withdrawing Employer then terminated) receive a benefit immediately after such discontinuance of participation which is equal to or greater than the benefit he or she would have been entitled to receive immediately before such discontinuance of participation if the Plan had then terminated. No transfer of assets pursuant to this section shall be effected until such statements with respect thereto, if any, required by ERISA to be filed in advance thereof have been filed. 14.03 ADOPTION OF PLAN BY UNRELATED EMPLOYERS. The Company may authorize companies that are not Affiliated Companies with respect to the Company to adopt the Plan. Such authorization may extend to an individual company or to a group of related companies. Any such company that is authorized to adopt the Plan for the benefit of its employees shall do so in accordance with Section 14.1. For purposes of such adoption and for purposes of its participation in the Plan, any such company shall be deemed to be an "Employer" hereunder and shall be subject to all terms of the Plan applicable to an Employer." 46.

Iowa Title A-1 ALL*AMERUS SAVINGS & RETIREMENT PLAN APPENDIX B: CALCULATION OF SUPPLEMENTAL PERCENTAGE Each Participant who was an active participant in the American Mutual Life Insurance Company Pension Plan, as amended and restated effective December 31, 1995, (the "DB Plan") on December 31, 1995, may receive an Interim Benefit Supplement. A Participant's annual Interim Benefit Supplement is the product of the Participant's Supplemental Percentage as determined below and the Participant's Compensation as determined in this Plan. The actuarial assumptions for determining the Supplemental Percentage are as follows: (a) Compensation is projected using a 4.5% salary scale; (b) The taxable wage base is assumed to increase 4.0% per year; (c) The Participant's accounts in any defined contribution plan are assumed to accrue 8.0% interest per year; (d) Conversion of a DC Plan account balance at age 65 to an annual benefit is accomplished by using the 1983 GAM mortality table (50% male/50% female) and 8% interest; and (e) Conversion of a DB Plan benefit to a single sum is accomplished using the 1983 GAM mortality table (50% male/50% female), and the annual interest rate on 30-year Treasury securities for August 1995 (6.86%). The procedure for determining the Supplemental Percentage is as follows: FIRST STEP. The first step is to determine the retirement benefit that a Participant would have received had the DB Plan (and any nonqualified plan of deferred compensation) covering that Participant not been frozen on December 31, 1995, and had the American Mutual and Central Life defined contribution plans which covered that Participant on December 31, 1995 ("DC Plans") remained in effect. This calculation is made as follows: (a) The Participant's Compensation at age 64 is projected; (b) The amount of annual retirement income the Participant would have received as a life annuity beginning at age 65 from the DB Plan, the DC Plans, and nonqualified plans of deferred compensation covering the Participant is determined by assuming the Participant remained covered under those plans until age 65, and assuming further that the provisions of such plans remained unchanged until the Participant's 65th birthday. For this purpose, it is assumed that a Participant covered under the American Mutual Plans described in Appendix D would receive a Company B-1 contribution equal to 4.5% of Compensation for each Plan Year until the Participant's 65th birthday, and Participants covered under the Central Life Plans described in Appendix C would receive an Employer contribution equal to 3.0% of Compensation until the Participant's 65th birthday. (c) The result in (b) is divided by the result in (a). SECOND STEP. The second step is to determine the retirement benefit that a Participant would receive under this Plan, the frozen DB Plan which covered him and any nonqualified plan of deferred compensation, if there were no Interim Benefit Supplement. This calculation is made as follows: (a) The amount of annual retirement income the Participant would have received as a life annuity beginning at age 65 is determined, assuming that he received Employer contributions equal to 9.0% of Compensation to his Accounts under this Plan beginning on January 1, 1996, and ending on the Participant's 65th birthday. (b) The amount of annual retirement income the Participant would have received from a life annuity beginning at age 65 is determined, assuming that he had transferred the single-sum value of his accrued benefit under the DB Plan to this Plan, transferred any "defined benefit" nonqualified plan balance to a nonqualified defined contribution plan and had not made withdrawals from the account holding such transferred amount. (c) The sum of (a) and (b) is divided by the Participant's projected Compensation at age 64. THIRD STEP. The third step is to determine the Supplemental Percentage. This calculation is performed as follows: (a) The result of the Second Step is subtracted from the First Step. If the result is 0 or less, the Supplemental Percentage is 0. (b) If (a) is greater than 0, the percentage of age 64 Compensation that is provided by a 1% Supplemental Percentage is determined. (c) Divide (a) by (b). This is the Supplemental Percentage. B-2 ALL*AMERUS SAVINGS & RETIREMENT PLAN APPENDIX C: CENTRAL LIFE PLAN C.01 BACKGROUND. Prior to January 1, 1996, certain Plan Participants were covered by the American Mutual Life Insurance Company Flexible Savings Plan ("Central Life Plan"). The accounts Participants had under the Central Life Plan have been transferred to this Plan.
