(c) The final determination of the exact amount of Other Retirement Income shall be made by the Administrative Committee and shall be binding upon all Participants. Article V. Benefits ------------------- 5.1 Retirement Benefits. ------------------- (a) A Participant who attains his Normal Retirement Date while employed by Boehringer shall be eligible to receive Supplemental Retirement Benefits under the Plan. The Supplemental Retirement Benefits will begin as soon as practical following the date of the Participant's Normal Retirement. A Participant's Supplemental Retirement Benefit will be an annual amount, payable for the Participant's lifetime, equal to-- (1) 60 percent of the Participant's Final Average Boehringer Income, reduced by (2) the sum of the Participant's Other Retirement Income, the benefit payable to the Participant under the RIP Plan and any benefit payable to the Participant under any defined benefit retirement arrangement maintained by Corange or by any non- United States based affiliate of Corange. (b) A Participant who attains his Early Retirement Date while employed by Boehringer and retires before his Normal Retirement Date shall be eligible to receive Supplemental Early Retirement Benefits under the Plan. The Supplemental Early Retirement Benefits will begin as soon as practical following the Participant's Early Retirement. Except as adjusted below, a Participant's Supplemental Early Retirement Benefits will be an annual amount computed in the same manner as Supplemental Retirement Benefits -10- under subsection (a). The following calculations shall be applied in determining the Supplemental Early Retirement Benefit: (i) The amount determined in section 5.1(a)(1) (before the application of the offset in section 5.1(a)(2)) shall be reduced to reflect the early commencement of the Benefit. The reduction for early commencement shall be .25 percent for each of the first 60 months and .41667 percent for each of the next 60 months (if any), that commencement of the Supplemental Early Retirement Benefits precedes the Participant's Normal Retirement Date. (ii) Additionally, if the Participant entered the Plan after January 1, 1992 and has completed fewer than ten complete years of service with Boehringer, his Supplemental Early Retirement Benefit (after reduction for early commencement) will be further reduced. The reduction shall be .41667 percent for each whole or fractional month that the Participant's years of service are less than ten years. This service reduction (in addition to the early commencement reduction) shall be applied to the amount determined under section 5.1(a)(1) before the application of the offset in section 5.1(a)(2), but after the application of the reduction in paragraph (i). (iii) Instead of the reductions described in paragraph (ii), if the Participant entered the Plan before January 1, 1992 and has completed fewer than five complete years of service with Boehringer, his Supplemental Early Retirement Benefit (after reduction for early commencement) will be further reduced. The reduction shall be .833 percent for each whole or fractional month that the Participant's years of service are less than five years, and this service reduction (in addition to the early commencement reduction) shall be applied to the amount determined under section 5.1(a)(1) before the application of the offset in section 5.1(a)(2), but after the application of the reduction in paragraph (i). -11- (c) A Participant who incurs a Disability while employed by Boehringer shall be eligible to receive Supplemental Disability Retirement Benefits under the Plan if the Participant completed five years of service with Boehringer or attained age 60 prior to the Participant's Disability Retirement Date. If a Participant is not enrolled in the Long-Term Disability Plan, the Participant shall receive no Supplemental Disability Retirement Benefits under this Plan. The Supplemental Disability Retirement Benefits will begin as soon as practical following the Participant's Disability Retirement Date. A Participant's Supplemental Disability Retirement Benefit will be an annual amount, payable for the Participant's lifetime, equal to-- (1) 60 percent of the Participant's Final Average Boehringer Income, reduced by (2) the sum of-- (A) the amount the Participant would be eligible to receive under the Long-Term Disability Plan (assuming the Participant selected the highest level of coverage available under such Plan), plus (B) the sum of the Participant's Other Retirement Income and the benefit payable to the Participant under the RIP Plan. The Participant's Supplemental Disability Retirement Benefit will not be reduced to reflect commencement thereof before the Participant's Normal Retirement Date or the Participant's failure to complete five years of service with Boehringer. If a Participant recovers from a Disability, his Supplemental Disability Retirement Benefits shall cease. Upon his subsequent Retirement or other termination of employment, he shall receive a benefit pursuant to the remaining provisions of this Plan, to the extent that he has satisfied the Plan requirements for such Benefits. 5.2 Death Benefits. -------------- (a) The Surviving Spouse of a participant will be eligible to receive a death benefit under this section 5.2(a) if the Participant dies while employed by Boehringer and prior to the commencement of benefits under section 5.1, but -12- after either (1) completing five years of service with Boehringer or (2) attaining age 60. The amount of such benefit will be annual amount equal to 50 percent of the annual amount of Supplemental Retirement Benefits which would have been payable to the Participant, based on his Boehringer Income at his death, if the Participant had retired on his Normal Retirement Date and been entitled to receive benefits under section 5.1(a). Such payments will begin on the first day of the month next following the date of the Participant's death. (b) The Surviving Spouse of a Participant will be eligible to receive a death benefit under this section 5.2(b) if the Participant dies after the commencement of Benefits under section 5.1 or 5.3. The amount of such benefit will be an annual amount equal to 50 percent of the annual amount of the Benefits payable to the Participant during his lifetime; provided, however, that for purposes of determining the amount of death benefit payable, the Benefits payable during the Participant's lifetime shall be recalculated by excluding from Other Retirement Income any primary Social Security benefit payable to the Surviving Spouse by reason of the Participant's death and by including any payments to the Surviving Spouse under the Long-Term Disability Plan. Such payments will begin on the first day of the month next following the date of the Participant's death. (c) The Surviving Spouse of a Participant will be eligible to receive a death benefit under this section 5.2(c) if the Participant dies after termination of employment with Boehringer and prior to the commencement of Supplemental Deferred Vested Benefits under section 5.3, but after completing ten years of service with Boehringer (five years if the Participant entered the Plan before January 1, 1992). The amount of such benefit will be an annual amount equal to 50 percent of the annual amount of Supplemental Deferred Vested Benefits which would have been available to the Participant under section 5.3 on the first day of the month next following the Participant's sixty-fifth birthday. Such payments will begin on the first day of the month -13- next following the date the Participant would have attained his sixty-fifth birthday. (d) Payments under this section will be continued to the Surviving Spouse until the Surviving Spouse's death. 5.3 Supplemental Deferred Vested Benefits. A Participant whose Employment ------------------------------------- with Boehringer is terminated after completing ten years of service with Boehringer (five years if the Participant entered the Plan before January 1, 1992) but before becoming eligible for Supplemental Retirement Benefits or Supplemental Early Retirement Benefits shall be eligible to receive Supplemental Deferred Vested Benefits under the Plan. The Supplemental Deferred Vested Benefits will begin on the first day of the month coincident with or next following the Participant's sixty-fifth birthday. A Participant's Supplemental Deferred Vested Benefits will be an annual amount computed in the same manner as Supplemental Retirement Benefits under section 5.1(a), based on his Final Average Boehringer Income at his termination of employment and his projected age 65 Other Retirement Income and benefit under the RIP Plan. 5.4 Commencement of Payments. ------------------------ (a) Except as otherwise specified in this section 5.4, benefits payable under sections 5.1, 5.2, and 5.3 will commence on the dates specified therein. (b) A Participant eligible for a benefit under 5.3 or a Surviving Spouse eligible for a benefit under section 5.2(c) may request earlier commencement of such benefit. The Administrative Committee may allow Benefits payable with respect to the Participant or survivors spouse to commence at any time after the Participant attains (or would have attained) age 55. (c) The Administrative Committee may grant early commencement of benefits upon the written petition of the Participant or, if the Participant is deceased, the Participant's Surviving Spouse. The approval or denial of such petition shall be in the sole discretion of the Administrative Committee. However, such petition may not be approved unless the Participant, or Surviving Spouse, -14- can demonstrate either (1) proof of financial need, (2) that such payment is in the best interest of Boehringer, or (3) that such payment will not result in a significant financial detriment to Boehringer. If benefits commence early under this section, they shall be reduced to reflect the early commencement thereof and shall be the Actuarial Equivalent of the Benefits otherwise payable under the Plan. 5.5 Form of Payments. ---------------- (a) Benefit payments under the Plan shall normally be made for the life of the Participant and his Surviving Spouse, as described elsewhere in this Article V. However, upon the written petition of the Participant (or the Participant's Surviving Spouse if the Participant is dead), the Administrative Committee may provide for all or any part of the benefits payable with respect to a Participant to be made in a single lump sum payment. The approval or denial of such petition shall be in the sole discretion of the Administrative Committee; provided, however, such petition may not be approved unless the Participant (or Surviving Spouse) can demonstrate either (1) proof of financial need, (2) that such payment is in the best interest of Boehringer, or (3) that such payment will not result in a significant financial detriment to Boehringer. A Participant who requests a lump sum payment as a condition of the Administrative Committee's approval, shall execute such other documents and agreements as are consistent with the terms of this Plan as the Administrative Committee may impose. (b) Lump sum payments under this section shall be the Actuarial Equivalent of the Benefits payable with respect to the Participant. 5.6 Calculation of Offsets and Actuarial Equivalence. ------------------------------------------------ (a) The Administrative Committee is authorized to interpret the terms of the Plan and calculate all Benefits payable under the Plan. Such interpretations shall comply with the rules contained in this section. Such calculations shall be made by, or with the guidance of, the Independent Actuary. However, -15- subsection (d) shall only apply to Participants who entered the Plan after January 1, 1992. (b) The offset under this Plant for a married Participant's Other Retirement Income and under the RIP Plan shall be calculated as a 50 percent joint and survivor annuity (with the Participant's Surviving Spouse as the contingent annuitant) beginning at the later of (1) the Participant's Retirement Date or (2) the earliest date that the Other Retirement Income or RIP payments are available. The offset under this Plan for an unmarried Participant's Other Retirement Income and under the RIP Plan shall be calculated as a single life annuity beginning on the later of (A) the Participant's Retirement Date or (B) the earliest date that the Other Retirement Income or RIP Plan payments are available. Such annuities shall be the Actuarial Equivalent of the amount of Other Retirement Income or the amount under the RIP Plan actually payable (or paid) to the Participant. (c) If a Participant (or his Surviving Spouse) is receiving payments under this Plan in a lump sum- (1) If the Participant's Other Retirement Income or benefit under the RIP Plan is either maintained in an individually-maintained account or is paid as a lump sum, then the offset for the Other Retirement Income or the benefit under the RIP Plan (as applicable) shall be determined on the basis of such account balance or lump sum as of the Retirement Date. (2) If the Participant's Other Retirement Income is maintained under a defined benefit plan, then the offset for the Other Retirement Income shall be determined as of the date payment of the lump sum under this Plan is payable. (d) If the payment of Other Retirement Income begins before the payment of Benefits under this Plant, the offset for the Other Retirement Income shall be based on the sum of (A) the amount of such Other Retirement Income payments made when Benefits are payable under this Plan, and (B) the -19- annuity equivalent of all payments made before Benefits are payable under this Plan, plus interest thereon. For purposes of this subsection (d), interest on any payments of Other Retirement Income shall be based on 120 percent of the interest rate used, by the Pension Benefit Guaranty Corporation, for valuing immediate annuities upon termination of defined benefit plans. The interest rate used shall be based on such PBGC rates as in effect on the first day of each Plan Year for the period between payment of the Other Retirement Income and the commencement of Benefits under this Plan. (e) For purposes of applying this section 5.6-- (1) If a benefit under this Plan is payable as a lump sum, a Participant's primary Social Security benefit will be based on the law in effect on his Retirement Date and will be determined on the assumption that the maximum Social Security benefits will increase at an annual rate equal to the Assumed Interest Rate in effect at the date on which payment of a Participant's Benefits commence, minus 200 basis points. (2) If the benefit under this Plan is payable as an annuity beginning before a participant's sixty-second birthday, the Participant's primary Social Security benefit will equal the maximum primary Social Security benefit based on the law in effect on the later of the Participant's Retirement Date or the Participant's sixty-second birthday. (f) In calculating Disability retirement benefits under section 5.3, the Social Security benefit used under paragraph (3) will be based on the actual Social Security disability award to the Participant. (g) The offset under this Plan for benefits under any defined retirement arrangement maintained by Corange or any of its non-United States based affiliates shall be calculated by the Administrative Committee, in its sole discretion, consistent with Section 5.6(b) above. (h) For purposes of Section 5.1(c) and Section 5.2(b), the offsets for amounts payable under the Long-Term Disability Plan shall only be effected for the -17- calendar months in which amounts are actually payable under the Long-Term Disability Plan. 5.7 Reductions for Certain Surviving Spouses. If a Surviving Spouse is ---------------------------------------- entitled to Benefits under this Article V, and if the Surviving Spouse is more than ten years younger than the Participant, the amount otherwise payable to the Surviving Spouse hereunder shall be reduced to reflect the actuarial value of such age difference. The Surviving Spouse's benefit shall be reduced so that it is the Actuarial Equivalent of the benefit payable to a Surviving Spouse who is ten years younger than the Participant. Article VI, Other Terminations of Employment --------------------------------------------- 6.1 Termination Before Five Years of Service. If a Participant's ---------------------------------------- Employment with Boehringer terminates for any reason other than Retirement, death or Disability before the Participant completes ten years of service with Boehringer (five years in the case of a Participant who entered the Plan before January 1, 1992), the Participant (and his Surviving Spouse) will not be entitled to any benefits under the Plan. If a Participant's Employment with Boehringer terminates due to death or Disability, and before the Participant completes five years of service with Boehringer or attains age 60, the Participant (and his Surviving Spouse) will not be entitled to any benefits under the Plan. 6.2 Termination for Cause. Notwithstanding anything to the contrary --------------------- contained elsewhere in this Plan, any Participant whose employment is terminated under circumstances that constitute Termination for Cause will not be entitled to any benefits under the Plan.

Article VIII. Miscellaneous --------------------------- 8.1 Amendment and Termination. The CEO or the Board may at any time ------------------------- terminate or amend the Plan in any respect.

Said trust is subject to the claims of creditors of Boehringer in the event of its insolvency. This Plan shall not be interpreted to provide any Participant or Surviving Spouse with any secured interest or right to any assets of Boehringer, and no Participant or Surviving Spouse shall acquire any interest greater than that of an unsecured creditor. (b) Boehringer shall make contributions to the trust no less often than twice per year. The Administrative Committee shall ensure that contributions are calculated using the guidance and methodology of Financial Accounting Standards Board statement No. 87. The first contribution required hereunder each year, to be made no later than July 1 of such year, shall fund the annual cost for the Participants on June 30 of such year. The second contribution required hereunder will be made no later than December 31 of each year. The second contribution shall fund the annual cost for individuals who become Participants in this Plan between July 1 and December 31 of such year.

The Plan and the rights and obligations of Boehringer ---------- hereunder shall be binding upon, and inure to the benefits of the Participants and their Surviving Spouse only, and the successors and assigns of Boehringer. 8.6 Severability. In the event that any one or more of the provisions of this ------------ Plan shall be held to be invalid, illegal, or unenforceable, the validity, legality, or enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 8.7 Nonuniform Determinations. The determinations of the CEO, the Board, or ------------------------- the Administrative Committee under the Plan need not be uniform and may be made selectively among Participants who receive, or are eligible to receive, Benefits under the Plan, whether or not such Participants are similarly situated. Such determination, however, may not result in payment to a Participant of an amount that is less than the amount that is otherwise provided for under the terms of this Plan. The Administrative Committee may, with the approval of the CEO on the Board, waive the application of specific provisions of the Plan for individual Participants. Such waivers may not adversely affect the Participant, and can be granted only if the waiver will not have a material adverse economic or competitive impact on the Plan or Boehringer. 8.8 Separation From Other Plans. Except as otherwise required by law, no --------------------------- Benefits under the Plan shall be taken into account in determining any benefit under any other pension, retirement, thrift, profit sharing, 401(k), group insurance, or other benefit plan maintained or hereafter established by Boehringer. 8.9 Effective Date.
