     Commitment for that year,  prohibit the Participant  from making any future
     Deferral  Commitments and/or distribute the Participant's  Account Balances

          Date in the same proportion  chosen by the Participant with respect to
          new deferrals as set forth above.

     c)   DISTRIBUTIONS.  Each  Account  shall be  reduced by the amount of each
          benefit  payment made from that Account since the prior  Determination
          Date.  Distributions  shall be deemed to have been made proportionally

          Valuation Funds maintained within such Account for that Participant as
          of the Determination Date immediately preceding the date of payment.

          Participant.

     from  any  or all  of  the  Participant's  Accounts.  The  amount  of  such
     distribution  shall be limited to the amount  reasonably  necessary to meet
     the   Participant's   needs  resulting  from  the  Financial   Hardship  or
     Disability,  and will not exceed the  Participant's  Account  balances.  If
     payment is made due to  Financial  Hardship,  the  Participant's  deferrals
     under this Plan shall  cease for the period of the  Financial  Hardship  or
     Disability  and for twelve (12) months  thereafter.  Any  resumption of the
     Participant's  deferrals under the Plan after such twelve (12) month period
     shall be made only at the election of the  Participant  in accordance  with
     Article III herein.

5.6. FORM OF PAYMENT.  Unless otherwise  specified in paragraphs 5.2 or 5.3, the
     benefits payable from any Account under this Plan shall be paid in the form
     of benefit as provided below,  and specified by the Participant in the Form
     of  Payment  Designation.  The  most  recently  submitted  Form of  Payment
     Designation  shall be  effective  for the  entire  Account  balance  unless
     amended

                                      -9-


     in writing by the  Participant  and delivered to the Committee.  If, at the
     time  payment of  benefits  under this Plan  become  due and  payable,  the
     Participant's  most  recent  election  as to the form of  payment  was made
     within one (1) year of such payment,  then the most recent election made by
     the  Participant  more that one year prior to the time of payment  shall be
     used to  determine  the form of  payment.  The  permitted  forms of benefit
     payments are:

     a)   A lump sum amount which is equal to the Account balance; and,

     b)   Annual  installments  for a period of up to ten (10)  years  where the
          annual   payment  shall  be  equal  to  the  balance  of  the  Account
          immediately  prior  to the  payment,  multiplied  by a  fraction,  the
          numerator of which is one (1) and the  denominator of which  commences
          at the number of annual payment initially chosen and is reduced by one
          (1) in each succeeding  year.  Earnings on the unpaid balance shall be
          based on the most  recent  allocation  among the  available  Valuation
          Funds chosen by the Participant,  made in accordance with Section 4.3,
          above.

5.7. SMALL ACCOUNT.  If the total of a Participant's  unpaid Account balances as
     of the Participant's Retirement is less than $50,000, the remaining unpaid,
     Account(s)  may be paid in a lump sum at the  discretion of the  Committee,
     notwithstanding any election by the Participant to the contrary.

5.8. WITHHOLDING;  PAYROLL  TAXES.  Company shall withhold from any payment made
     pursuant to this Plan any taxes  required to be withheld from such payments
     under local, state or federal law. A Beneficiary, however, may elect not to
     have  withholding of federal  income tax pursuant to Section  3405(a)(2) of
     the Code, or any successor provision thereto.

5.9. PAYMENT TO  GUARDIAN.  If a Plan  benefit is payable to a minor or a person
     declared  incompetent or to a person  incapable of handling the disposition
     of the property,  the Committee may direct  payment to the guardian,  legal
     representative  or  person  having  the care  and  custody  of such  minor,
     incompetent  or person.  The Committee  may require proof of  incompetency,
     minority,  incapacity or guardianship as it may deem  appropriate  prior to
     distribution.  Such distribution  shall completely  discharge the Committee
     and Company from all liability with respect to such benefit.

5.10.EFFECT OF PAYMENT.  The full payment of the  applicable  benefit under this
     Article V shall  completely  discharge all  obligations  on the part of the
     Company to the Participant (and the Participant's Beneficiary) with respect
     to the operation of this Plan,  and the  Participant's  (and  Participant's
     Beneficiary's) rights under this Plan shall terminate.


                      ARTICLE VI - BENEFICIARY DESIGNATION


6.1. BENEFICIARY  DESIGNATION.  Each  Participant  shall have the right,  at any
     time, to designate one (1) or more persons or entity as  Beneficiary  (both
     primary as well as  secondary)  to whom  benefits  under this Plan shall be
     paid in the event of Participant's death prior to complete  distribution of
     the Participant's Account balance. Each Beneficiary designation shall be in
     a written form prescribed by the Committee and shall be effective only when
     filed with the

                                      -10-


     Committee  during  the  Participant's  lifetime.  Designation  by a married
     Participant to the Participant's  spouse of less than a fifty percent (50%)
     interest  in the  benefit  due shall not be  effective  unless  the  spouse
     executes a written consent that acknowledges the effect of the designation,
     or it is established that the consent cannot be obtained because the spouse
     cannot be located.

6.2. CHANGING  BENEFICIARY.  Any  Beneficiary  designation  may be changed by an
     unmarried   Participant   without  the  consent  of  the  previously  named
     Beneficiary  by  the  filing  of a new  Beneficiary  designation  with  the
     Committee. A married Participant's  Beneficiary  designation may be changed
     by a Participant with the consent of the  Participant's  spouse as provided
     for in Section 6.1 above. The filing of a new designation  shall cancel all
     designations previously filed.

6.3. CHANGE IN MARITAL STATUS. If the Participant's marital status changes after
     the Participant has designated a Beneficiary, the following shall apply:

     a)   If the  Participant  is  married at death but was  unmarried  when the
          designation was made, the designation  shall be void unless the spouse
          has consented to it in the manner prescribed in Section 6.1 above.

     b)   If the  Participant  is  unmarried  at death but was married  when the
          designation was made:

          i)   The  designation  shall  be  void  if the  spouse  was  named  as
               Beneficiary.

          ii)  The designation shall remain valid if the spouse was not name and
               a non-spouse  Beneficiary  was named.


     c)   If the  Participant  was married when the  designation was made and is
          married to a different spouse at death, the designation  shall be void
          unless the new spouse has consented to it in the manner  prescribed in
          Section 6.1 above.

6.4.  NO  BENEFICIARY  DESIGNATION.  If any  Participant  fails to  designate  a
      Beneficiary in the manner  provided  above, if the designation is void, or
      if the Beneficiary  designated by a deceased  Participant  dies before the
      Participant or before complete distribution of the Participant's benefits,
      the  Participant's  Beneficiary  shall be the  person  in the first of the
      following classes in which there is a survivor:

      a)   The Participant's surviving spouse;

      b)  The Participant's  children in equal shares, except that if any of the
          children  predeceases the Participant but leaves surviving issue, then
          such  issue  shall  take by  right of  representation  the  share  the
          deceased  child  would  have  taken if  living;

      c)   The Participant's estate.

6.5. EFFECT OF PAYMENT.  Payment to the Beneficiary  shall completely  discharge
     the Company's obligations under this Plan.

                                     -11-

9.2. COMPANY'S  RIGHT TO  TERMINATE.  The  Board  may at any time  partially  or

                            ARTICLE X - MISCELLANEOUS

10.1.UNFUNDED  PLAN.  This plan is an  unfunded  plan  maintained  primarily  to
     provide deferred compensation benefits for a select group of "management or
     highly-compensated  employees" within the meaning of Sections 201, 301, and
     401 of the Employee  Retirement  Income  Security  Act of 1974,  as amended
     ("ERISA"),  and therefore is exempt from the provisions of Parts 2, 3 and 4
     of Title I of ERISA. Accordingly, the Board may terminate the Plan and make
     no further benefit payments or remove certain  employees as Participants if
     it is  determined  by the United  States  Department  of Labor,  a court of
     competent jurisdiction,  or an opinion of counsel that the Plan constitutes
     an  employee  pension  benefit  plan within the meaning of Section 3 (2) of
     ERISA (as currently in effect or hereafter amended) which is not so exempt.

10.2.COMPANY  OBLIGATION.  The  obligation  to  make  benefit  payments  to  any
     Participant under the Plan shall be an obligation solely of the appropriate
     Company with  respect to the deferred  Compensation  receivable  from,  and
     contributions  by, that Company and shall not be an  obligation  of another

     appropriate  Company or any other party for payment of benefits  under this
     Plan.  Any property held by Company for the purpose of generating  the cash
     flow  for  benefit  payments  shall  remain  its  general,   unpledged  and
     unrestricted  assets.  Company's  obligation  under  the  Plan  shall be an
     unfunded and unsecured promise to pay money in the future.

10.4.TRUST FUND.  Company shall be  responsible  for the payment of all benefits
     provided under the Plan. At its  discretion,  Company may establish one (1)
     or more  trusts,  with such  trustees  as the Board  may  approve,  for the
     purpose of assisting in the payment of such benefits. Although such a trust
     shall be irrevocable, its assets shall be held for payment of all Company's
     general  creditors in the event of  insolvency.  To the extent any benefits
     provided under the Plan are paid from any such trust, Company shall have no
     further  obligation to pay them. If not paid from the trust,  such benefits
     shall remain the obligation of Company.

10.5.NONASSIGNABILITY.  Neither a  Participant  nor any other  person shall have
     any right to commute, sell, assign, transfer, pledge, anticipate,  mortgage
     or otherwise encumber, transfer, hypothecate or convey in advance of actual
     receipt the amounts, if any, payable hereunder,  or any part thereof, which
     are, and all rights to which are, expressly declared to be unassignable and
     non-transferable.  No part of the amounts  payable  shall,  prior to actual
     payment,  be subject to seizure  or  sequestration  for the  payment of any
     debts, judgements, alimony or separate maintenance owed by a Participant or
     any other person, nor be transferable by operation of law in the event of a
     Participant's or any other person's bankruptcy or insolvency.

10.6.NOT A CONTRACT OF EMPLOYMENT.  This Plan shall not constitute a contract of
     employment between Company and the Participant.  Nothing in this Plan shall
     give a Participant the right to be retained in the service of Company or to
     interfere  with the right of the  Company  to  discipline  or  discharge  a
     Participant at any time.
                                      -14-


10.7.PROTECTIVE  PROVISIONS.  A  Participant  will  cooperate  with  Company  by
     furnishing  any and all  information  requested  by  Company,  in  order to
     facilitate the payment of benefits  hereunder,  and by taking such physical
     examinations  as Company may deem necessary and taking such other action as
     may be requested by Company.

10.8.GOVERNING  LAW.  The  provisions  of  this  Plan  shall  be  construed  and
     interpreted according to the laws of the State of Iowa, except as preempted
     by federal law.

     such illegal and invalid provision had never been inserted herein.

10.10.NOTICE.  Any  notice  required  or  permitted  under  the  Plan  shall  be
     sufficient  if in  writing  and hand  delivered  or sent by  registered  or
