Item 5.           OTHER EVENTS.

         On October 22, 1997,  the Board of Directors  (the  "Board") of Casey's
General  Stores,  Inc.  (the  "Company"),  acting  on a  recommendation  of  its
Compensation  Committee,  approved  of  several  changes to the  employment  and
retirement  arrangements  with the Company's  four executive  officers  (Messrs.
Lamberti,  Lamb,  Shull  and  Harmon)  (each  an  "Officer"  and  together,  the
"Officers").  The Board's  actions  included  the  approval  of a  Non-Qualified
Supplemental  Executive  Retirement  Plan (the "SERP"),  providing by means of a
plan for the payment of retirement benefits to the Officers at substantially the
same benefit  levels and under  substantially  the same terms and  conditions as
such benefits were payable under the Officers' most recent employment contracts,
and a Non-Qualified  Supplemental Executive Retirement Plan Trust Agreement (the
"Trust  Agreement")  with  UMB  Bank,  n.a.,  intended  to  secure  the  payment
obligations  of the  Company  under the SERP  following a change of control or a
potential change of control of the Company.

         The SERP is an unfunded plan and a non-qualified  deferred compensation
plan under the Internal Revenue Code of 1986 (the "Code"). The SERP provides for
the payment of annual  retirement  benefits to the  Officers,  commencing on the
first day of the calendar year immediately  following the calendar year in which
the Officer's  Retirement Date occurs (the "Benefit Date") and continuing  until
the Officer's  death.  For this purpose,  the  Retirement  Date of an Officer is
deemed to be the earlier of the first day of the month immediately following the
month during which the Officer (i)  voluntarily  terminates his employment  with
the Company after attaining his Early  Retirement Age (defined to mean age 59 in
the case of Messrs.  Lamberti and Lamb,  age 58 in the case of Mr. Shull and age
55 in the case of Mr.  Harmon) or (ii) attains age 65.  Following  the Officer's
death the payments  would continue to be made to his surviving  spouse,  if any,
until the earlier of the expiration of the period ending on the twentieth (20th)
anniversary of the Benefit Date or the death of the Officer's spouse.

         In the case of  Messrs.  Lamberti  and Lamb,  the  amount of the annual
retirement  benefit  payable  under the SERP will be the sum of one-half of such
Officer's salary for the year during which his retirement occurs. In the case of
Mr. Shull, the amount of the annual retirement benefit would be one-third of his
salary for the year  during  which he attains age 58 plus an  additional  amount
equal to 2.4% of his salary for each  additional  full year of his employment by
the Company  thereafter until he reaches age 65. In the case of Mr. Harmon,  the
amount of the annual  retirement  benefit  would be one-fourth of his salary for
the year during which he attains age 55 plus an additional  amount equal to 5.0%
of his salary for each full  additional  year of his  employment  by the Company
thereafter until he reaches age 60.

         The SERP provides that if an Officer's employment by the Company 
terminates


<PAGE>



before he reaches his Early Retirement Age, whether with or without cause, or if
an Officer's  employment  by the Company is  terminated  for cause,  no benefits
shall be payable to the Officer under the SERP. At the present time,  therefore,
Messrs.  Lamberti and Lamb (who  currently are age 60 and age 61,  respectively)
each are eligible to receive retirement benefits under the SERP upon a voluntary
termination of his employment.  Messrs.  Shull and Harmon (who currently are age
54 and age 43, respectively) will not be eligible to receive retirement benefits
under the SERP unless and until they reach  their  respective  Early  Retirement
Ages and thereafter voluntarily terminate their employment with the Company.

         The Trust  Agreement  is intended to create a grantor  trust (or "rabbi
trust") (the "Trust")  within the meaning of Section 671 of the Code, and is not
intended  to qualify  under  Section  401(a) of the Code.  Following a change of
control or a potential  change of control  (as defined in the Trust  Agreement),
the  Company  is  required  by the  SERP  and  the  Trust  Agreement  to  make a
contribution  to the Trust equal in amount to the maximum amount that may become
payable to the Officers under the SERP (calculated  under the Officer's  current
salaries to be $9.8 million). The maximum amount payable under the SERP is to be
calculated by a firm of independent public  accountants or consulting  actuaries
of  recognized  national  standing as the Trustee (UMB Bank,  n.a.) shall select
(the "Consulting  Firm"). The Company's  contribution to the Trust is to be made
in cash or  pursuant  to an  irrevocable  and  unconditional  letter  of  credit
established by the Company for that purpose.

         The Trustee is required to perform all accounting  functions related to
the Trust and to invest the Trust  assets.  The  Consulting  Firm is required to
establish  and maintain a  memorandum  account for each Officer and to calculate
the  amount  due to each  Officer  under  the SERP and to credit  the  Officer's
accounts with all payments made. The Trustee is directed to make payments to the
Officers  from the  Trust  assets in  accordance  with the  instructions  of the
Consulting  Firm. The Trust assets are at all times subject to claims of general
creditors  of the  Company,  and no  payments  from the Trust may be made in the
event the Company is insolvent.

         At its meeting on October 22, 1997,  the Board also approved of Amended
and Restated Employment Agreements (together,  the "Employment Agreements") with
each of the  Officers,  continuing  their  employment  under the same  terms and
conditions  approved  by the  Board  on March  2,  1992 (in the case of  Messrs.
Lamberti,  Lamb and Shull) and July 19, 1994 (in the case of Mr. Harmon), and as
amended by the Board on December 9, 1996, but modifying each Officer's agreement
(i) to  eliminate  those  provisions  providing  for the  payment of  retirement
benefits to the Officer under the agreement,  (ii) to add an "alternative excise
tax cap"  provision  limiting  the  payments  or  benefits  to be received by an
Officer  whose  employment  is  terminated  following  a change of control to an
amount equal to 2.99 times the Officer's "base amount" determined in


<PAGE>



accordance with Section 280G of the Code and any temporary or final  regulations
promulgated under that Section,  (iii) to add a provision permitting the Company
to defer the payment of any portion of an Officer's severance payment that would
not be deductible by the Company in the taxable year in which the payment is due
by virtue of the "reasonable  compensation" limitations of Section 162(m) of the
Code to a date sixteen months following the date of termination and (iv) to make
other conforming and editorial changes.

         Attached hereto as Exhibits 10.30, 10.31, 10.21(a),  10.22(a), 10.23(a)
and 10.24(a) and incorporated  herein by reference are copies of the SERP, Trust
Agreement and the Employment Agreements.  The foregoing description is qualified
in its entirety by reference to the full text of said documents.

a number  equal to the  number of years of his Life  Expectancy  or (ii)  twenty
(20);

                  b. For Lamb,  the amount equal to one-half (1/2) of his Salary

Change of Control,  as the case may be) shall occur multiplied times the greater

58) or (ii) twenty (20);

                  d. In the case of Harmon, an amount equal to one-half (1/2) of
his Salary for the Plan Year  during  which a Change of Control  (or a Potential
Change of Control,  as the case may be) shall occur multiplied times the greater
of (i) a number equal to the number of years of his Life  Expectancy if he shall
have then  attained  age 55 (or if he shall not have then  attained  age 55, the
number of years of his Life Expectancy  assuming he shall have then attained age
55) or (ii) twenty (20);

                          Casey's General Stores, Inc.
      Non-Qualified Supplemental Executive Retirement Plan Trust Agreement


         This Trust  Agreement is made as of this 24th day of October,  1997, by
and between Casey's General Stores,  Inc., an Iowa  corporation (the "Company"),
and UMB Bank,  n.a.  (the  "Trustee").  This Trust  Agreement  provides  for the
establishment  of a trust  to be  known  as the  Casey's  General  Stores,  Inc.
Non-Qualified  Supplemental  Executive  Retirement  Plan Trust (the  "Trust") to
provide a source for  payments  required  to be made under the  Casey's  General
Stores, Inc.  Non-Qualified  Supplemental Executive Retirement Plan (the "Plan")
for the benefit of certain of the  Company's  senior  executive  officers  named
therein (the "Participants") and their spouses.

                                   WITNESSETH:

         WHEREAS,  the Company will  transfer to the Trustee  certain  assets in
trust,  subject to the  claims of the  Company's  creditors  in the event of the
Company's  insolvency or  bankruptcy,  until paid to the  Participants  or their
spouses upon the terms and conditions stated in this Trust Agreement; and

         WHEREAS,  it is the intention of the Company to make  contributions  in
addition to the Initial  Contribution  (as defined in Section  1(a) below) (such
additional   contributions   are   referred   to  herein   as  the   "Additional
Contributions"  and,  together  with the Initial  Contribution,  are referred to
collectively as the  "Contributions")  to the Trustee upon or in anticipation of
the  occurrence of a Change of Control (as defined in Section 3(a) below) of the
Company.

         NOW,  THEREFORE,  the parties hereto do hereby  establish the Trust and
agree that the Trust shall be comprised,  held,  administered and disposed of as
follows:

         Section 1.  TRUST FUND

         (a)  Subject to the claims of its  creditors  as set forth in Section 5
hereof,  the  Company  hereby  deposits  with the  Trustee in trust One  Hundred
Dollars  ($100.00) (the "Initial  Contribution")  which shall become the initial
principal of the Trust to be held,  administered  and disposed of by the Trustee
as provided in this Trust  Agreement.  The Trustee  shall have no  obligation to
invest the Initial Contribution in an interest-bearing account.

         (b)      The Trust is intended to be a grantor trust, within the 
meaning of Section


<PAGE>



671 of the Internal Revenue Code of 1986, as amended (the "Code"),  and shall be
construed accordingly.  The purpose of the Trust is to assure that the Company's
obligations to the Participants pursuant to the Plan are fulfilled. The Trust is
not intended to qualify under Section 401(a) of the Code.

         (c)  The  principal  of  the  Trust  and  any  earnings  thereon  (such
principal,  together  with any  earnings  thereon and other  increases  thereof,
reduced by any losses and distributions  from the Trust and any other reductions
thereof,  is sometimes  referred to herein as the "Trust  Assets") shall be held
separate and apart from other funds of the Company and shall be used exclusively
for the uses and purposes herein set forth. The Participants  shall not have any
preferred  claim on, or any beneficial  ownership  interest in, any of the Trust
Assets  prior to the time any of the Trust  Assets are paid to the  Participants
pursuant to the terms of this Trust Agreement,  and all rights created under the
Plan and this Trust Agreement shall be mere unsecured  contractual rights of the
Participants against the Company.

         (d) Except as provided in the second succeeding  sentence,  the Trustee
shall  have  full  discretion  in and sole  responsibility  for the  investment,
management and control of the Trust Assets.  Without  limiting such  discretion,
the Company  requests,  but does not direct,  that the  Trustee,  based upon the
nature of this Trust, only make short-term investments with a stated maturity of
twelve (12) months or less from the date of purchase by the  Trustee.  The Trust
Assets  shall only be invested in  obligations  of or  guaranteed  by the United
States of America, in commercial paper obligations  receiving the highest rating
from either Moody's Investors Service, Inc. or Standard & Poor's Rating Group or
a  similar  rating  service  or in  certificates  of  deposit,  bank  repurchase
agreements or bankers acceptances (including those of the Trustee) of commercial
banks with  capital  exceeding  $1,000,000,000  the  securities  of which or the
securities of the holding company of which are rated in the highest  category by
a   nationally-recognized   credit  agency   ("Permitted   Investments")  or  in
money-market funds which are invested solely in Permitted Investments.

         (e) The advisor to the Trust (the "Consulting Firm") shall be such firm
of independent public accountants or consulting actuaries of recognized national
standing  as the  Trustee  shall  select  following  a Change  of  Control  or a
Potential  Change of Control (each as defined  herein).  It is not intended that
the Consulting Firm act in a fiduciary capacity under the Plan or the Trust.

         Section 2.   CONTRIBUTIONS

         (a) Except as provided  in Section  2(b)  hereof,  the Company may make
such  Contributions  to the Trust as the Board of Directors of the Company deems
appropriate from time to time.


<PAGE>



         (b) As soon as practicable following a Change of Control (as defined in
Section 3(a) hereof),  the Consulting Firm shall calculate the maximum aggregate
amount due pursuant to the Plan (without  regard to the present  value  thereof)
(the aggregate of such amounts is hereinafter referred to as the "Maximum Amount
Payable").  The Consulting Firm shall promptly  furnish such  calculation to the
Company  and  the  Company  shall  have  the   obligation  to  make   Additional
Contributions  to the Trust,  and shall  make  Additional  Contributions  to the
Trust, within three (3) business days of the receipt of such calculation,  in an
amount equal to the excess (the "Excess"), if any, of the Maximum Amount Payable
over the then fair market value of the Trust Assets, or shall direct the Trustee
to draw down a Letter of Credit (as defined in Section  2(d) hereof) held by the
Trust in such  amount for such  purpose.  If at any time  following  a Change of
Control, a valuation of the Trust Assets occurs pursuant to this Trust Agreement
and it is  determined  by the  Consulting  Firm that an Excess shall exist,  the
Company shall  promptly  contribute  such amount to the Trust as is necessary to
eliminate  the Excess,  or the Trustee shall be authorized to draw down a Letter
of Credit held by the Trust in such amount.

         (c)  Anything   contained  in  Section  2(b)  hereof  to  the  contrary
notwithstanding,  in the event of a  Potential  Change of Control (as defined in
Section 3(b) hereof),  the Company shall have the obligation to make  Additional
Contributions  to the Trust in an amount  equal to the  Excess,  or the  Trustee
shall be  authorized  to draw down a Letter of Credit  held by the Trust in such
amount.  If a Change of Control shall not have occurred  within ninety (90) days
of a Contribution  made pursuant to this Section 2(c) and the Board of Directors
adopts a resolution to the effect that, for purposes of this Trust Agreement,  a
Change of Control is not imminent, any amounts contributed to the Trust pursuant
to this Section 2(c), together with any earnings thereon, shall be promptly paid
by the Trustee to the Company.

         (d) The Company shall make all required  Contributions  to the Trust in
cash  or,  alternatively,  may  provide  the  Trustee  with an  irrevocable  and
unconditional  letter of credit  (the  "Letter of  Credit")  sufficient  for the
Trustee to draw down an amount  equal to all required  Contributions.  If at any
time the Trust has been  provided  with a Letter of Credit by the  Company,  the
Consulting  Firm will direct the Trustee (i) when to draw down on such Letter of
Credit and in what amount and (ii) whether, if necessary, to renew the Letter of
Credit or change its amount or terms. All  Contributions so received  (including
any cash  received  on the draw down of a Letter of Credit),  together  with the
income  therefrom  and  any  increment  thereon,  shall  be  held,  managed  and
administered by the Trustee as a single  commingled  Trust pursuant to the terms
of this Trust  Agreement  without  distinction  between  principal  and  income.
Neither the Trustee nor the  Consulting  Firm shall have any duty to require any
Contributions to be made to the Trustee by the Company or to determine whether a
Change of Control or Potential Change of Control has occurred.



<PAGE>



         (e) Anything in Section 2 hereof to the contrary  notwithstanding,  the
Trustee  shall return to the Company as soon as feasible  following the close of
each calendar quar ter within each calendar year the excess,  if any, of (i) the
then aggregate fair market value of the Trust Assets over (ii) one hundred fifty
percent  (150%) of the Maximum Amount  Payable,  as determined by the Consulting
Firm at the request of the Company.

         (f) The  Company  may at any time or from time to time make  Additional
Contributions to the Trustee, which shall be held,  administered and disposed of
by Trustee as provided in this Trust Agreement.

         Section 3.   CHANGE OF CONTROL

         (a)      For purposes of this Trust Agreement, a "Change of Control" 
shall mean:

                  (i)  The  acquisition  (other  than  from  the  Company  in  a
transaction  approved by the  Incumbent  Board (as  defined in Section  3(a)(ii)
below)) by any person,  entity or "group" within the meaning of Section 13(d)(3)
or  14(d)(2)  of the  Securities  Exchange  Act of  1934  (the  "Exchange  Act")
(excluding,  for this purpose, the Company or its subsidiaries,  or any employee
benefit  plan of the  Company  or its  subsidiaries  which  acquires  beneficial
ownership of voting securities of the Company with the approval of a majority of
the Incumbent Board) of beneficial  ownership  (within the meaning of Rule 13d-3
promulgated  under the Exchange  Act) of twenty  percent (20%) or more of either
the then  outstanding  shares of the Company's  Common Stock,  no par value (the
"Common Stock") or the combined  voting power of the Company's then  outstanding
voting  securities in a transaction or series of transactions  not approved by a
vote of at least a majority of the Incumbent Board (as defined below); or

                  (ii) The failure of  individuals  who, as of the date  hereof,
constitute the Board of Directors of the Company (the "Incumbent Board") for any
reason  to  constitute  at least a  majority  of the Board of  Directors  of the
Company,  provided  that any person  becoming a director  subsequent to the date
hereof whose election, or nomination for election by the Company's shareholders,
was approved by a vote of at least a majority of the  directors  comprising  the
Incumbent  Board (other than an election or nomination  of an  individual  whose
initial  assumption  of office  is in  connection  with an actual or  threatened
election  contest  relating to the election of the directors of the Company,  as
such  terms are used in Rule  14a-11 of  Regulation  14A  promulgated  under the
Exchange  Act) shall be, for  purposes of this Trust  Agreement,  considered  as
though such person were a member of the Incumbent Board; or

                  (iii) The  approval  by the  stockholders  of the Company of a
reorganization, merger or consolidation (in each case, with respect to which the
stockholders of the Company do not, immediately thereafter,  own more than fifty
percent


<PAGE>



(50%) of the combined  voting power of the  reorganized,  merged or consolidated
company's then outstanding voting  securities),  of a liquidation or dissolution
of the Company or of the sale of all or  substantially  all of the assets of the
Company.

         (b) For  purposes  of this  Trust  Agreement,  a  "Potential  Change of
Control"  shall be deemed to have  occurred if (i) any third person  commences a
tender or  exchange  offer  (other  than a tender or exchange  offer  which,  if
consummated,  would not result in a Change of Control) for twenty  percent (20%)
or more of the then outstanding  shares of Common Stock or combined voting power
of the Company's then  outstanding  voting  securities;  (ii) the Company enters
into an agreement, the consummation of which would result in the occurrence of a
Change of Control;  (iii) any person (including the Company) publicly  announces
an intention to take or to consider  taking actions which if  consummated  would
constitute  a Change of Control;  or (iv) the Board of  Directors of the Company
adopts a resolution to the effect that, for purposes of this Trust Agreement,  a
Change of Control is imminent.

         (c) The  Company  shall  have a duty to inform the  Trustee  whenever a
Change of  Control  or  Potential  Change of Control  has  occurred.  If any two
Participants notify the Trustee in writing that a Change of Control or Potential
Change of Control  has  occurred  then,  unless,  in the  opinion of  nationally
recognized counsel to the Company (which opinion may be based on representations
of fact as long as counsel does not know that such  representations  are untrue)
such a Change of Control or  Potential  Change of Control  has not  occurred,  a
Change of Control or Potential Change of Control will be deemed to have occurred
for purposes of this Trust Agreement.

         Section 4.   ACCOUNTING BY THE TRUSTEE AND CONSULTING FIRM

         (a) The  Trustee  shall  keep  accurate  and  detailed  records  of all
investments,  receipts,  disbursements and all other transactions required to be
done, including such specific records as shall be agreed upon in writing between
the Company and the Trustee.  Within sixty (60) days following the close of each
calendar year and within sixty (60) days after the removal or resignation of the
Trustee,  the Trustee  shall  deliver to the Company and the  Consulting  Firm a
written  account of its  administration  of the Trust during such year or during
the period from the close of the last preceding year to the date of such removal
or resignation, setting forth all investments, receipts, disbursements and other
transactions  effected by it,  including a  description  of all  securities  and
investments  purchased and sold with the cost or net proceeds of such  purchases
or sales (accrued interest paid or receivable being shown  separately),  showing
all cash,  securities  and other  property  held in the Trust at the end of such
year or as of the date of such removal or  resignation,  as the case may be, and
the book and fair market value of any such asset. The Consulting Firm shall send
a copy of any written account to each Participant at the address provided by the
Company.


<PAGE>



         (b) As soon  as  practicable  following  a  Change  of  Control  of the
Company,  the  Consulting  Firm shall (i)  establish  and  maintain a memorandum
account  for each  Participant  with  respect  to the Plan  (the  "Participant's
Account") and (ii)  calculate the amount which would be due to each  Participant
(or the Participant's spouse) upon satisfaction of the conditions under the Plan
which  give rise to the  obligation  of the  Company  to pay such  amount to the
Participant (or the Participant's spouse) (the "Plan Payments").  The Consulting
Firm shall credit each  Participant's  Account with the Plan  Payments and shall
debit the Participant's Account with any amounts paid to the Participant (or the
Participant's spouse) with respect to the Plan by the Company or the Trustee.

         (c) The Company  shall furnish the  Consulting  Firm with copies of the
Plan and any and all amendments  thereto.  The Company will promptly provide the
Consulting  Firm with a copy of any notice of  termination  given by the Company
with respect to any  Participant  and will also promptly  provide the Consulting
Firm with any and all  additional  information  the Consulting  Firm  reasonably
requests or the Company believes would be useful to the Consulting Firm in order
to enable the  Consulting  Firm to determine  the amount of Plan  Payments  with
respect to each  Participant  and to effect such Plan Payments and will promptly
update such information as it changes.  The Company will use its best efforts to
cause each  Participant to provide the Consulting Firm with all information that
it may reasonably request in order to determine the amount of Plan Payments with
respect to the Participant.  The Trustee shall notify the Consulting Firm of any
payment  made  from the Trust to the  Participant  or the  Participant's  spouse
pursuant to the terms of the Plan, in each case, so that the Consulting Firm may
debit the Participant's Account.

         (d) All accounts,  books and records  maintained  pursuant to Section 4
shall be open to inspection and audit at all reasonable times by the Company and
on an annual basis by the Participants;  provided,  however, that no Participant
shall have access to information about another  Participant's Account other than
in the normal course of performing his duties as an employee of the Company.

         (e) The fair market value of the Trust Assets  shall be  determined  by
the Trustee whenever required pursuant to this Trust Agreement, but in any event
not less than  quarterly.  The  Trustee  may base such  determination  upon such
sources of information as it may deem reliable,  including,  but not limited to,
information  reported in (i)  newspapers of general  circulation,  (ii) standard
financial periodicals or publications, (iii) statistical and valuation services,
(iv) the  records of  securities  exchanges  or  brokerage  firms  deemed by the
Trustee  to be  reliable  or (v) any  combination  thereof.  The  Trustee  shall
promptly inform the Consulting Firm of any such valuation.

         Section 5.  PAYMENTS TO THE PARTICIPANTS


<PAGE>



         (a)  The  Trustee  shall  make  payments  to the  Participants  (or the
Participants'  spouses) from the Trust  Assets,  if and to the extent such Trust
Assets are available for distribution, in accordance with the provisions of this
Trust  Agreement,  provided  that the  Company is not  Insolvent  (as defined in
Section 6(a)) at the time any such payment is required to be made.

         (b) Subject to Section 5(a) hereof,  the Consulting Firm shall,  within
five (5)  business  days of the date a payment is  required to be made under the
Plan, notify and direct the Trustee to pay the Participant (or the Participant's
spouse) an amount  equal to the lesser of the amount so  required  to be paid or
the then credit balance in the Participant's Account; provided, however, that if
the aggregate of the then credit balances in the Participants'  Accounts exceeds
the then fair market value of the Trust Assets,  then the Consulting  Firm shall
direct the Trustee to pay to the Participant (or the  Participant's  spouse) the
lesser of the  amount  so  required  to be paid or such  portion  of the  credit
balance  in the  Participant's  Account  which is  equal to (a) the full  credit
balance  in the  Participant's  Account  multiplied  by (b) a  fraction  (i) the
numerator  of which is the then fair market  value of the Trust  Assets and (ii)
the  denominator  of which is the  aggregate of the then credit  balances in the
Participants' Accounts.

         (c) Whenever the Consulting Firm notifies the Trustee to make a payment
to a Participant  (or the  Participant's  spouse),  the Trustee shall supply the
Consulting  Firm with the current fair market  value of the Trust Assets  within
two (2) business  days so that the  Consulting  Firm may make the  determination
required hereunder.  The Trustee shall pay the Participant (or the Participant's
spouse) the amount set forth in the notice from the Consulting  Firm within five
(5) business days of receiving notice from the Consulting Firm.

         (d) For the purposes of this Trust Agreement, the Consulting Firm shall
determine,  pursuant  to the  terms  of the  Plan,  when a  Participant  (or the
Participant's spouse) is entitled to receive a payment thereunder and the amount
thereof.  The Trustee  shall be under no duty to make  inquiry as to whether the
determination  made by the  Consulting  Firm is correct or whether  any  payment
amount is proper and correct.

         (e) Anything in this Trust  Agreement to the contrary  notwithstanding,
all  payments  pursuant to this  Section 5 may be made  without the  approval or
direction of the Company, shall be made despite any direction to the contrary by
the Company and shall be made upon the direction of the Consulting Firm.

         (f) If the Trust Assets are not  sufficient to make all payments to the
Participants  required to be made pursuant to the terms of the Plan, the Company
shall pay to each  Participant the balance of each such payment as it falls due.
If such  payments  are not made by the  Company,  and the Trust  later  contains
sufficient Trust Assets to make


<PAGE>



such payments,  they shall be made from the Trust Assets, together with interest
at the rate determined  pursuant to Section 1274(d) of the Code,  subject to the
requirements of Sections 5(a) and 5(b) hereof.

         Section 6.  TRUSTEE RESPONSIBILITY REGARDING PAYMENTS WHEN
COMPANY INSOLVENT

                  (a) The Company shall be considered  "Insolvent"  for purposes
of this Trust  Agreement  if (i) the  Company is unable to pay its debts as they
mature, or (ii) the Company is subject to a pending proceeding as a debtor under
the United States Bankruptcy Code or any similar law of any state.

                  (b) At all times  during the  continuance  of this Trust,  the
Trust Assets  shall be subject to claims of general  creditors of the Company as
hereinafter set forth, and at any time the Trustee has actual knowledge,  or has
determined,  that the  Company is  Insolvent,  the  Trustee  shall  deliver  any
undistributed  Trust  Assets to  satisfy  such  claims  as a court of  competent
jurisdiction may direct.  The Chief Executive  Officer of the Company shall have
the duty to inform the Trustee of the Company's Insolvency.  If the Company or a
person  claiming  to be a  creditor  of the  Company  alleges  in writing to the
Trustee that the Company has become Insolvent,  the Trustee shall  independently
determine,  within  thirty (30) days after  receipt of such notice,  whether the
Company  is  Insolvent  and,  pending  such  determination,  the  Trustee  shall
discontinue  payments to the  Participants,  shall hold the Trust Assets for the
potential  benefit of the Company's  general creditors and shall resume payments
to the  Participants  in accordance  with Section 5 of this Trust Agreement only
after the Trustee has  determined  that the Company is not  Insolvent  (or is no
longer  Insolvent,  if  the  Trustee  initially  determines  the  Company  to be
Insolvent).  If the Trustee,  after the  expiration of such thirty (30) days, in
good faith and with the advice of such  advisors as may be retained  pursuant to
Section 7 hereof, is unable to determine  whether the Company is Insolvent,  the
Trustee (i) shall so notify the Company and the Consulting  Firm in writing (and
the Consulting Firm shall promptly notify the Participants (or their spouses) at
the address supplied by the Company) and any of the Trustee,  the Company or the
Participants  (or any of the  Participants'  spouses)  may apply to any court of
competent  jurisdiction for a  determination,  for purposes of this Trust, as to
whether or not the Company is Insolvent,  and (ii) the Trustee  shall  thereupon
hold the Trust Assets pursuant to the terms of this Trust Agreement  pending the
determination  of such court.  Unless the Trustee  has actual  knowledge  of the
Company's  Insolvency,  the  Trustee  shall have no duty to inquire  whether the
Company  is  Insolvent.  The  Trustee  may in all events  rely on such  evidence
concerning  the  Company's  solvency as may be  furnished to the Trustee as will
give the Trustee a reasonable  basis for making a  determination  concerning the
Company's  solvency.  Nothing in this Trust  Agreement shall in any way diminish
any rights of a  Participant  (or a  Participant's  spouse) to pursue his or her
rights as a general creditor of the Company with respect to the Plan or


<PAGE>



otherwise.

                  (c) If the Trustee discontinues payments from the Trust to any
Participant  (or  to a  Participant's  spouse)  pursuant  to  Section  6(b)  and
subsequently   resumes  such   payments,   the  first  payment   following  such
discontinuance  shall,  subject to Sections  5(a) and 5(b)  hereof,  include the
aggregate  amount of all payments which would have been made to the  Participant
(or to the Participant's spouse),  together with interest at the rate determined
pursuant to Section 1274 of the Code on the amount delayed, during the period of
such  discontinuance,  less  the  aggregate  amount  of  payments  made  to each
Participant  (or to the  Participant's  spouse)  by the  Company  in lieu of the
payments  provided for hereunder  during any such period of  discontinuance,  as
certified to the Trustee by the Consulting Firm.

         Section 7.   RESPONSIBILITY OF TRUSTEE AND THE CONSULTING FIRM

         (a) The Trustee shall act with the care, skill,  prudence and diligence
under the  circumstances  then prevailing that a prudent person acting in a like
capacity  and  familiar  with  such  matters  would  use  in the  conduct  of an
enterprise of a like character and with like aims; provided,  however,  that the
Trustee  shall incur no liability  to anyone for any action taken  pursuant to a
direction,  request or approval given by the Company, the Consulting Firm or any
Participant  contemplated  by  and  complying  with  the  terms  of  this  Trust
Agreement.  The Trustee shall discharge its  responsibility  for the investment,
management  and  control  of the  Trust  Assets  solely in the  interest  of the
Participants  (and the  Participants'  spouses) and for the exclusive purpose of
assuring  that, to the extent of available  Trust Assets,  all Plan Payments are
paid when due to the Participants (or to the Participants' spouses).

         (b) Neither the  Trustee nor the  Consulting  Firm shall be required to
undertake  or to defend any  litigation  arising in  connection  with this Trust
Agreement, unless it be first indemnified by the Company against its prospective
costs,  expenses and  liability,  and the Company hereby agrees to indemnify the
Trustee and the Consulting Firm for such costs, expenses and liability.

         (c) The Trustee and the Consulting  Firm may consult with legal counsel
(who may also be counsel for the Trustee or the Consulting  Firm generally) with
respect  to any of its  duties  or  obligations  hereunder  and  shall  be fully
protected in acting or refraining  from acting in accordance  with the advice of
such counsel.

         (d)      The Trustee may hire agents, accountants and financial 
consultants.

         (e)      The Trustee is authorized and empowered:



<PAGE>



     (i) To purchase,  hold, sell,  invest and reinvest the assets of the Trust,
together with income therefrom;

     (ii) To hold, maintain and control all property at any time forming part of
the Trust Assets;

     (iii)  To  sell,  convey,  transfer,  exchange  and  otherwise
dispose  of the  Trust  Assets  from  time  to time in  such  manner,  for  such
consideration and upon such terms and conditions as it shall determine;

      (iv)     To make payments from the Trust as provided hereunder; and

      (v) To exercise all the further  rights,  powers,  options and
privileges  granted,   provided  for  or  vested  in  trustees  generally  under
applicable  Federal or State of Missouri  law, as amended from time to time,  it
being intended that, except as herein otherwise  provided,  the powers conferred
upon the Trustee  herein shall not be construed  as being in  limitation  of any
authority conferred by law, but shall be construed as in addition thereto.

      (f) The Trustee in any and all events is authorized and empowered to do
all other acts necessary or desirable for the proper administration of the Trust
Assets, as though the absolute owner thereof, including, but not limited to, the
authorization and power:

                  (i) To cause any of the Trust  Assets  to be  issued,  held or
registered  in the name of the  Trustee,  in the name of its  nominee or in such
form that title will pass by  delivery,  provided,  the  records of the  Trustee
shall indicate the true ownership of such property;

                  (ii)     To employ such agents and counsel as may be 
reasonably necessary in managing and protecting the Trust Assets and to pay 
them reasonable compensation; and

                  (iii) To settle, compromise or abandon with the consent of the
Company all claims and demands from other than the  Participants  or the Company
in favor of or against the Trust Assets.

         Section 8.  COMPENSATION AND EXPENSES OF TRUSTEE AND
CONSULTING FIRM

         The Trustee and the  Consulting  Firm shall each be entitled to receive
such reasonable  compensation  for their services as shall be agreed upon by the
Company and


<PAGE>



the  Trustee or the  Consulting  Firm,  as the case may be. The  Trustee and the
Consulting Firm shall each also be entitled to receive their reasonable expenses
incurred with respect to the administration of the Trust, including counsel fees
and fees  incurred by the Trustee and the  Consulting  Firm pursuant to Sections
7(b),  7(c),  7(d) and 7(f) hereof.  Such  compensation  and  expenses  shall be
payable by the Company and if not so paid, shall be paid by the Trustee from the
Trust  Assets.  In the event any Trust Assets are used pursuant to the preceding
sentence to pay compensation and expenses to the Trustee or Consulting Firm, the
Company  shall  promptly  contribute to the Trust any such amount (or direct the
Trustee to draw down on a Letter of Credit held by the Trust in such amount).

         Section 9.  RESIGNATION AND REPLACEMENT OF TRUSTEE

         (a) The Trustee may resign at any time during the term of this Trust by
delivering  to the  Company  and the  Consulting  Firm a  written  notice of the
proposed  resignation.  The  Consulting  Firm  shall  deliver a copy of any such
notice to each Participant or his spouse at the address supplied by the Company.
Such resignation shall take effect upon the qualification of a successor Trustee
and such successor Trustee commencing to act as such.

         (b) In the  event  that,  prior to a Change  of  Control,  the  Trustee
notifies  the  Company  of its  intention  to  resign,  in  accordance  with the
foregoing  provisions  of this Section 9, the Company  shall appoint a successor
Trustee  which shall be a bank or trust  company.  The Trustee  shall  thereupon
deliver  to the  successor  Trustee  all the Trust  Assets,  together  with such
records and  documents  as may be  reasonably  required to enable the  successor
Trustee to properly administer the Trust,  reserving such funds as it reasonably
deems necessary to cover its unpaid bills, expenses and closing costs.

         (c) Upon  qualification of a successor  Trustee,  all right,  title and
interest  of the  resigning  Trustee  in the Trust  Assets  and all  rights  and
privileges  under  this Trust  Agreement  theretofore  vested in such  resigning
Trustee shall vest in the successor Trustee where applicable,  and thereupon all
future liability of said resigning Trustee shall terminate;  provided,  however,
that the Trustee  shall  execute,  acknowledge  and deliver  all  documents  and
written  instruments  which are  necessary  to assign,  transfer  and convey the
right,  title and interest in the Trust Assets and all rights and  privileges of
the Trustee to the successor Trustee.

         (d) Nothing in this Trust  Agreement  shall be interpreted as depriving
the  Trustee or the  Company of the right to have a judicial  settlement  of the
Trustee's  accounts,  and upon any proceeding  for a judicial  settlement of the
Trustee's  accounts or for instructions the only necessary  parties thereto will
be the Trustee and the Company.

         Section 10.  AMENDMENT OR TERMINATION


<PAGE>



         (a) This Trust  Agreement  may be amended at any time prior to the time
any  Additional  Contribution  is  made  (or,  after  the  time  any  Additional
Contribution is made if such Additional  Contribution is returned to the Company
in accordance with Section 2(c) hereof) and to any extent (including  amendments
to add  other  agreements,  contracts  or  plans  between  the  Company  and the
Participants  or other key  employees) by a written  instrument  executed by the
Trustee and the Company.

         (b) This Trust shall be revocable by the Company  prior to the time any
Additional  Contribution  is made or required  to be made  pursuant to the terms
hereof and may be terminated  by the Company  prior thereto (or,  after the time
any Additional  Contribution is made if such Additional Contribution is returned
to the Company in accordance with Section 2(c) hereof).  After the occurrence of
a Change of Control,  the Trust shall  remain in effect until the receipt by the
Trustee of a certification  from the Consulting Firm that all liabilities  under
the Plan have been satisfied;  provided that, if any payment made from the Trust
or to be made pursuant to the Plan is being  contested or  litigated,  the Trust
shall remain in effect until such contest, litigation or dispute is resolved.

         (c) At the  termination  of the Trust  pursuant to Section  10(b),  the
Trustee shall as soon as  practicable,  but in any event within ninety (90) days
of the date of such termination,  transfer to the Company the value of the Trust
Assets as of the termination date.

         Section 11.  PROTECTION OF THE TRUSTEE AND THE CONSULTING
FIRM

indemnify  the Trustee and the  Consulting  Firm and hold them harmless from and
against any claim or  liability  that may be asserted  against them by reason of
their taking or  refraining  from taking any action under this Trust  Agreement,
including,  without limiting the generality of the foregoing,  any claim brought
against  the  Trustee  or the  Consulting  Firm  by the  Company,  in any  case,
otherwise  than  on  account  of the  Trustee's  or the  Consulting  Firm's  own
negligence or willful misconduct.

         (b)  The  Trustee   shall  be  fully   protected   in  relying  upon  a
certification of an authorized  representative  of the Company or the Consulting
Firm with  respect to any  instruction,  direction or approval of the Company or
the Consulting Firm until a subsequent certification is filed with the Trustee.

         (c) The Trustee and the Consulting  Firm shall each be fully  protected
in acting  upon any  instrument,  certificate  or paper  believed  by them to be
genuine  and to be signed or  presented  by the proper  person or  persons,  and
neither the Trustee nor the Consulting


<PAGE>



Firm  shall be under any duty to make any  investigation  or  inquiry  as to any
statement  contained in any such  writing but may accept the same as  conclusive
evidence of the truth and accuracy of the statements therein contained.

         (d) The Trustee shall not be liable for the proper  application  of any
part of the Trust Assets if distributions  are made in accordance with the terms
of  this  Trust  Agreement  and  information  furnished  to the  Trustee  by the
Consulting  Firm. All persons dealing with the Trustee are released from inquiry
into the decision or authority of the Trustee and from seeing to the application

therein; and

         WHEREAS,  the Board of  Directors  has  further  determined  that it is
appropriate  and in the best  interests of the Company and its  shareholders  to
modify  the  existing  contractual   arrangements  with  respect  to  Lamberti's
employment by the Company,  with the  concurrence of Lamberti,  and to amend and
restate the Original Agreement to reflect the same; and

         WHEREAS,  the Board of Directors has further  determined  that it is in
the best interest of the Company and its shareholders to assure that the Company
will have the continued dedication of Lamberti, notwithstanding the possibility,
threat or occurrence  of a Change of Control (as defined  below) of the Company,
and to further encourage Lamberti's full attention and dedication to the Company
currently and in the event of any threatened or pending  Change of Control,  and
to provide  Lamberti  with  compensation  arrangements  upon a Change of Control
which provide him with  compensation for expected losses that he would suffer in

<PAGE>



competitive with those of other corporations,  and, in order to accomplish these
objectives, has determined to cause the Company to enter into this Agreement.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
set forth in this Agreement, the parties hereto agree as follows:

          1.      CERTAIN DEFINITIONS.  For purposes of this Agreement, and in
addition to the other definitions set forth herein, the following terms shall 
have the following meanings:

         a)       "Change of Control" shall mean:

                  (i) the  acquisition  (other  than  from the  Company)  by any
Person (as hereinafter defined), entity or "group" within the meaning of Section

Act"),  (excluding for this purpose, the Company or any employee benefit plan of
the Company,  which acquires  beneficial  ownership of voting  securities of the
Company) of beneficial  ownership  (within the meaning of Rule 13d-3 promulgated
under the  Exchange  Act) of  twenty  percent  (20%) or more of either  the then
outstanding shares of Common Stock, no par value, of the Company or the combined
voting power of the Company's then  outstanding  voting  securities  entitled to
vote  generally  in the election of  directors  (hereinafter  referred to as the
"Common Stock"), unless such beneficial ownership was acquired as a result of an
acquisition  of shares of Common  Stock by the Company  which,  by reducing  the
number of  shares  outstanding,  increases  the  proportionate  number of shares
beneficially owned by such Person,  entity or "group" to twenty percent (20%) or
more of the Common Stock of the Company  then  outstanding;  provided,  however,
that if a Person,  entity or "group" shall become the beneficial owner of twenty
percent  (20%) or more of the Common  Stock of the Company then  outstanding  by
reason of share  purchases by the Company and shall,  after such share purchases
by the Company,  become the beneficial owner of any additional  shares of Common
Stock of the  Company,  then such Person,  entity or "group"  shall be deemed to
have met the conditions hereof; or

                  (ii)  individuals  who, as of the date hereof,  constitute the
Board of Directors (as of the date hereof,  the "Incumbent Board") cease for any
reason to  constitute  at least a majority of the Board of  Directors,  provided
that  any  person  becoming  a  director  subsequent  to the date  hereof  whose
election, or nomination for election by the Company's shareholders, was approved
by a vote of at least a majority of the directors then  comprising the Incumbent
Board  (other than an election or  nomination  of an  individual  whose  initial
assumption  of office is in  connection  with an actual or  threatened  election
contest relating to the election of the directors of the Company,  as such terms
are used in Rule 14a-11 of Regulation  14A  promulgated  under the Exchange Act)
shall be, for purposes of this Agreement considered as though such person were a
member of the


<PAGE>



Incumbent Board; or

                  (iii)  approval  by  the  shareholders  of  the  Company  of a
reorganization,  merger,  consolidation  (in each  case,  with  respect to which
persons  who were the  shareholders  of the  Company  immediately  prior to such
reorganization, merger or consolidation do not, immediately thereafter, own more
than fifty percent (50%) of the combined voting power entitled to vote generally
in  the  election  of  directors  of the  reorganized,  merged  or  consolidated
company's then outstanding voting securities) or a liquidation or dissolution of
the  Company  or of the sale of all or  substantially  all of the  assets of the
Company.

         (b) "Annual Increase" shall take effect on each January 1 for which the

increase in the National Consumer Price Index for the City of Des Moines,  Iowa,
as published by the United States Bureau of Labor Statistics.

         (c) "Annual  Bonus" shall mean any bonus  payable at the  discretion of
the Board of Directors  of the Company,  on such terms and in such amounts as it
shall determine.

         (d)  "Employment  Period" shall mean the term of Lamberti's  employment
under this Agreement, as set forth in Section 2 hereof.

         (e)      "Code" shall mean the Internal Revenue Code of 1986, as 
amended.

         (f) "Accrued  Obligations" shall mean (i) Lamberti's Salary through the
Date of Termination at the rate in effect on the Date of  Termination,  (ii) the
product of the Annual Bonus paid to Lamberti for the last full fiscal year and a
fraction,  the  numerator  of which is the number of days in the current  fiscal
year through the Date of  Termination,  and the  denominator of which is 365 and
(iii) any compensation  previously  deferred (together with any accrued interest
thereon)  and not yet paid by the Company and any accrued  vacation  pay not yet
paid by the Company.

         (g) "Person"  shall mean any  individual,  firm,  corporation  or other
entity,  and shall  include  any  successor  (by  merger or  otherwise)  and all
"affiliates" and "associates" of such entity (as those terms are defined in Rule
12b-2 of the General Rules and Regulations under the Exchange Act).

     2. EMPLOYMENT AND TERM. The Company agrees to employ Lamberti, and Lamberti
agrees to serve the Company,  as Chief  Executive  Officer of the Company on the
terms and under the conditions set forth in this Agreement.  The initial term of
employment  under this  Agreement  shall  commence  on the date hereof and shall
terminate

<PAGE>



on April 30,  1998 (the  "Initial  Term"),  after which this  Agreement  and the
Employment  Period  hereunder  shall be  automatically  renewed and extended for
successive  periods of three years  (each of which  shall be a "Renewal  Term"),
subject to the right of the Company and  Lamberti to  terminate  this  Agreement
during the Initial Term or any such Renewal  Term in  accordance  with the terms
and conditions set forth in subsequent  sections of this Agreement,  and further
subject to the right of the Company and Lamberti to cause this Agreement and the
Employment  Period  hereunder  to expire at the end of the  Initial  Term or any
Renewal Term by giving written notice thereof at least one year prior to the end
of the Initial Term or the then current  Renewal Term, as applicable;  provided,
however, that in the event of a Change of Control during the Initial Term or any
Renewal Term, this Agreement and the Employment  Period hereunder  automatically
shall  continue  in full force and effect for the  greater of (i) the  remaining
term of employment  then in progress or (ii) three years from the effective date
of the Change of Control. References herein to the Employment Period shall refer
to both the Initial Term and any successive Renewal Term.

         3.  DUTIES OF  LAMBERTI.  During  the period of his  employment  in the
capacity of Chief  Executive  Officer,  Lamberti  will perform his duties to the
best of his  ability,  subject to the control of the Board of  Directors.  It is
agreed and understood that the position  (including  status,  office,  title and
reporting  requirements),  authority,  duties and  responsibilities  of Lamberti
shall  be  substantially  the  same as  those  performed  by  Lamberti  as Chief
Executive  Officer of the Company prior to the date of this Agreement,  and that
Lamberti shall at all times serve the best interests of the Company. The Company
agrees that Lamberti shall at all times have such authority and discretion as is
required in the  carrying  out of  Lamberti's  duties in a proper and  efficient
manner, subject to review by the Board of Directors.

         During the period of his  employment,  it shall not be a  violation  of
this  Agreement  for  Lamberti to (i) serve on  corporate,  civil or  charitable
boards or committees,  (ii) deliver lectures or fulfill speaking engagements and
(iii)  manage  personal   investments,   so  long  as  such  activities  do  not
significantly  interfere with the performance of Lamberti's  responsibilities as
an employee of the Company in accordance  with this  Agreement.  It is expressly
understood  and agreed  that to the extent  that any such  activities  have been
conducted by Lamberti  prior to the date hereof,  the continued  conduct of such
activities  (or the conduct of activities  similar in nature and scope  thereto)
subsequent to the date hereof shall not  thereafter be deemed to interfere  with
the performance of Lamberti's responsibilities to the Company.

     4.  COMPENSATION.  The Company  shall pay to  Lamberti an annual  salary of
Three Hundred and Fifty Thousand  Dollars  ($350,000),  payable in equal monthly
installments,  or such  other  amount as shall be  mutually  agreed  upon by the
Company and Lamberti (the "Salary").  In addition,  Lamberti  and/or  Lamberti's
family shall be entitled

<PAGE>



to receive all  benefits  presently  provided or those  which may  hereafter  be
generally  provided by the  Company to its  employees,  officers  or  directors,
including  health  insurance  and life  insurance.  With  respect to such health
insurance  benefits,  the Company agrees that at all times the health  insurance
coverages  available to Lamberti  and his spouse under such plans shall  include
provisions providing for lifetime benefits payable on behalf of Lamberti and his
spouse of not less than One Million  Dollars  ($1,000,000)  each,  or such other
amount as the  Company  and  Lamberti  may  specifically  agree upon in writing,
subject, however, to any limitations, restrictions or conditions that shall from
time to time be necessary to satisfy the  requirements of applicable  federal or
state laws and regulations.

         5.  TERMINATION  OF  EMPLOYMENT.  (a) Death or  Disability.  Lamberti's
employment  under this Agreement shall terminate  automatically  upon Lamberti's
death.  If the Company  determines in good faith that the Disability of Lamberti
has occurred  (pursuant to the definition of "Disability"  set forth below),  it
may give to Lamberti  written  notice of its  intention to terminate  Lamberti's
employment as Chief Executive Officer of the Company. In such event,  Lamberti's
employment  with the Company shall terminate  effective on the thirtieth  (30th)
day after receipt of such notice by Lamberti (the "Disability  Effective Date"),
provided  that,  within the thirty (30) days after such receipt,  Lamberti shall
not have returned to full-time  performance of his duties.  For purposes of this
Agreement,  "Disability"  means  disability or incapacity of Lamberti  which, at
least twenty-six (26) weeks after its  commencement,  is determined by the Board
of Directors  upon competent  medical  advice to be such as to prevent  Lamberti
from performing  substantially  all of the duties of Chief Executive  Officer of
the Company.

         (b) Cause. The Company may terminate Lamberti's employment for "Cause."
For  purposes of this  Agreement,  "Cause"  means (i) an act or acts of personal
dishonesty  taken by Lamberti  and  intended to result in  substantial  personal
enrichment of Lamberti at the expense of the Company,  (ii) repeated  violations
by Lamberti of Lamberti's  obligations  under Section 3 of this Agreement  which
are  demonstrably  willful and  deliberate on Lamberti's  part and which are not
remedied in a reasonable period of time after receipt of written notice from the
Company or (iii) the conviction of Lamberti of a felony when such  conviction is
no longer subject to direct appeal.

     (c) Good Reason.  Lamberti's  employment  may be terminated by Lamberti for
Good Reason. For purposes of this Agreement, "Good Reason" means:

                  (i) the assignment to Lamberti of any duties  inconsistent  in
any respect with  Lamberti's  position  (including  status,  office,  titles and
reporting requirements),  authority,  duties or responsibilities as contemplated
by Section 3 of this Agreement, or any other action by the Company which results
in a  diminution  in  such  position,  authority,  duties  or  responsibilities,
excluding for this purpose an isolated, insubstantial and


<PAGE>



inadvertent  action not taken in bad faith and which is  remedied by the Company
promptly after receipt of notice thereof given by Lamberti;

                  (ii) Any failure by the Company to comply with the  provisions
of  Section 4 of this  Agreement,  other  than an  isolated,  insubstantial  and
inadvertent  failure  not  occurring  in bad faith and which is  remedied by the
Company promptly after receipt of notice thereof given by Lamberti;

                  (iii)  the  Company's  requiring  Lamberti  to be based at any
office or location other than the Company's Corporate  Headquarters  facility in
Ankeny,  Iowa,  except for travel  reasonably  required  in the  performance  of
Lamberti's responsibilities;

                  (iv)     any purported termination by the Company of 
Lamberti's employment otherwise than for death, Disability or Cause as 
expressly permitted by this Agreement; or

                  (v)      any failure by the Company to comply with and satisfy
Section 13(c) of this Agreement.

         For  purposes of this Section  5(c),  any good faith  determination  of
"Good Reason" made by Lamberti shall be conclusive.

         (d) NOTICE OF TERMINATION.  Any termination by the Company for Cause or
by Lamberti for Good Reason shall be  communicated  by Notice of  Termination to
the other party hereto given in accordance with Section 14(b) of this Agreement.
For purposes of this Agreement, a "Notice of Termination" means a written notice
which (i) indicates the specific termination  provision in this Agreement relied
upon, (ii) sets forth in reasonable detail the facts and  circumstances  claimed
to provide a basis for termination of Lamberti's  employment under the provision
so indicated and (iii) if the Date of  Termination  (as defined  below) is other
than the date of receipt of such notice,  specifies the termination  date (which
date shall be not more than fifteen (15) days after the giving of such  notice).
The failure of Lamberti  to set forth in the Notice of  Termination  any fact or
circumstance  which  contributes to a showing of Good Reason shall not waive any
right of Lamberti  hereunder or preclude  Lamberti from  asserting  such fact or
circumstance in enforcing his rights hereunder.

         (e)  DATE OF  TERMINATION.  "Date  of  Termination"  means  the date of
receipt of the Notice of Termination or any later date specified therein, as the
case may be; provided,  however, that (i) if Lamberti's employment is terminated
by the Company other than for Cause or Disability, the Date of Termination shall
be the date on which the Company notifies  Lamberti of such termination and (ii)
if Lamberti's  employment is  terminated by reason of death or  Disability,  the
Date of Termination shall be the date of


<PAGE>



death of Lamberti or the Disability Effective Date, as the case may be.

         6.       OBLIGATIONS OF THE COMPANY UPON TERMINATION OF
EMPLOYMENT.

         (a) Death of Lamberti. In the event of the death of Lamberti during the
term hereof, the Company shall pay to Lamberti's spouse, commencing on the first
day of the month  following his death and continuing for a period of twenty-four
(24) months  thereafter,  benefits equal to the monthly  installments  of Salary
which was then being paid to Lamberti pursuant to Section 4 herein.  Immediately
following  such  two-year  period,  the Company  shall  commence  the payment of
monthly benefits to Lamberti's spouse equal in amount to one-fourth (1/4) of the
monthly  installments  of Salary which was being paid to Lamberti at the time of
his death under  Section 4 herein,  which monthly  benefits  shall be paid for a
period of twenty (20) years or until the death of Lamberti's  spouse,  whichever
occurs first. In addition,  the Company shall continue at all times to offer and
provide health insurance  coverage to Lamberti's  spouse, in accordance with the
plans, programs,  practices and policies provided by the Company under the terms
of this Agreement at the time of Lamberti's death, until the death of Lamberti's
spouse,  except to the extent such coverage is or otherwise becomes available to
Lamberti's spouse under the Medicare program of benefits.

         (b) Disability of Lamberti.  If Lamberti's  employment is terminated by
reason of the Disability of Lamberti, Lamberti's employment under this Agreement
shall  terminate  without  further  obligations  to  Lamberti,  other than those
obligations  accrued or earned and vested (if  applicable) by Lamberti as of the
Date of  Termination,  including for this purpose,  all Accrued  Obligations and
those set forth herein.  All such Accrued  Obligations shall be paid to Lamberti
in a lump  sum in cash  within  thirty  (30)  days of the  Date of  Termination.
Anything in this  Agreement to the contrary  notwithstanding,  Lamberti shall be
entitled  after the Disability  Effective  Date to receive  disability and other
benefits in an amount  equal to  one-half  (1/2) of his Salary  (adjusted  on an
annual  basis by the amount of the Annual  Increase),  which shall be payable in
equal  monthly  installments  until the close of the calendar  year during which
Lamberti attains sixty-five (65) years of age or until the last day of the month
in which Lamberti is no longer deemed disabled  pursuant to this  Agreement,  or
until Lamberti's death, whichever shall first occur.

         If Lamberti  shall receive any  disability  payments from any insurance
policies  paid for by the  Company,  the  payments to Lamberti  pursuant to this
provision  shall be reduced by the amount of  disability  payments  received  by
Lamberti under any such insurance policy or policies.

         If, following the termination of Lamberti's employment by reason of 
Disability, the


<PAGE>



Board of Directors determines,  upon competent medical advice, that Lamberti has
recovered from said  Disability to the point where he is no longer  prevented by
said  Disability  from  performing  substantially  all of the  duties  as  Chief
Executive Officer of the Company,  the Company shall give Lamberti not less than
thirty  (30)  days  written  notice of its  election  to cease  the  payment  of
Disability  benefits to him pursuant to this Section 6(b),  following  which (i)
the  Company  shall  have no  further  obligations  to  Lamberti  to  make  said
Disability  payments as provided  herein and (ii) Lamberti  thereafter  shall be
entitled  to retire and  terminate  his  employment  with the  Company,  without
further action or notice on his part, and to receive the benefits  payable under
the Non- Qualified  Supplemental  Executive  Retirement Plan of the Company (the
"SERP") (or any successor  plan),  as and to the extent set forth  therein,  and
shall hold  himself  available  to the Board of Directors  for  consultation  as
provided in Section 10 hereof.

         Notwithstanding  any  Disability  on the part of Lamberti,  the Company
shall continue at all times to offer and provide health  insurance  coverages to
Lamberti and his spouse, in accordance with the most favorable plans,  programs,
practices  and  policies  provided  by the  Company  during  the  90-day  period
immediately  preceding the  Disability  Effective  Date or, if more favorable to
Lamberti,  as in  effect  at any time  thereafter  with  respect  to  other  key
employees and their families, until the death of Lamberti and his spouse, except
to the extent such  coverage is or otherwise  becomes  available to Lamberti and
his spouse under the Medicare program of benefits.

         (c) CAUSE;  OTHER THAN FOR GOOD REASON. If Lamberti's  employment shall
be  terminated  for Cause,  Lamberti's  employment  under this  Agreement  shall
terminate without further  obligations to Lamberti (other than the obligation to
pay to Lamberti his Salary  through the Date of  Termination  plus the amount of
any compensation previously deferred by Lamberti, together with accrued interest
thereon).  If Lamberti  terminates  employment other than for Good Reason,  this
Agreement shall terminate  without further  obligations to Lamberti,  other than
those  obligations  accrued or earned and vested  (if  applicable)  by  Lamberti
through  the Date of  Termination,  including  for  this  purpose,  all  Accrued
Obligations.  All such Accrued  Obligations  shall be paid to Lamberti in a lump
sum in cash within thirty (30) days of the Date of Termination.

         (d) GOOD  REASON;  OTHER THAN FOR CAUSE OR  DISABILITY.  If the Company
shall terminate Lamberti's employment other than for Cause, Disability, or death
or if Lamberti shall terminate his employment for Good Reason at any time during
the Employment Period, except during a three-year period following any Change of
Control (in which case the provisions of Section 6(e) shall apply), then in such
event:

                  (i) the  Company  shall pay to  Lamberti in a lump sum in cash
within  thirty  (30) days after the Date of  Termination  the  aggregate  of the
following amounts:



<PAGE>



         A.       to the extent not theretofore paid, Lamberti's Salary through
the Date of Termination; and

         B.       the product of (x) the highest Annual Bonus paid to Lamberti
during the three (3) fiscal years preceding the fiscal year in which the Date of
Termination  occurs (the "Recent  Bonus") and (y) a fraction,  the  numerator of
which is the  number of days in the  current  fiscal  year  through  the date of
Termination and the denominator of which is 365; and

         C.       the product of (x) two (2.0) and (y) the sum of (i) the Salary
and (ii) the Recent Bonus; and

         D.       in the case of compensation previously deferred by Lamberti,
all amounts previously deferred (together with any accrued interest thereon) and
not yet paid by the  Company,  and any accrued  vacation pay not yet paid by the
Company; and

                  (ii) for a two-year period  following the Date of Termination,
the Company shall  continue  benefits to Lamberti  and/or  Lamberti's  family at
least equal to those which would have been provided to them in  accordance  with
the plans,  programs,  practices and policies  provided  under this Agreement if
Lamberti's  employment had not been  terminated,  including health insurance and
life insurance, in accordance with the most favorable plans, practices, programs
or  policies  provided by the  Company  and its  subsidiaries  during the 90-day
period  immediately  preceding the Date of Termination  or, if more favorable to
Lamberti,  as in  effect  at any time  thereafter  with  respect  to  other  key
employees  and their  families.  Notwithstanding  the  foregoing,  however,  the
Company  shall  continue at all times to offer and  provide the  above-described
health  insurance  coverages to Lamberti  and his spouse until their  respective
dates of death,  except to the extent  such  coverage  is or  otherwise  becomes
available to Lamberti and his spouse under the Medicare program of benefits.

         (e) GOOD REASON; OTHER THAN FOR CAUSE OR DISABILITY, FOLLOWING A CHANGE
OF CONTROL.  If, during a three year period following any Change of Control, the
Company shall terminate Lamberti's employment other than for Cause,  Disability,
or death or if Lamberti shall terminate his employment for Good Reason:

                  (i) the Company shall pay to Lamberti in a lump sum in cash on
the thirtieth  (30th) day following the Date of Termination the aggregate of the
following amounts:

         A.       to the extent not theretofore paid, Lamberti's Salary through
the Date of Termination; and


<PAGE>



         B.       the product of (x) the Recent Bonus and (y) a fraction, the
numerator of which is the number of days in the current fiscal year through the 
date of Termination and the denominator of which is 365; and

         C.       the product of (x) three (3.0) and (y) the sum of (i) the 
Salary and (ii) the Recent Bonus; and

         D.       in the case of compensation previously deferred by Lamberti,
all amounts previously deferred (together with any accrued interest thereon) and
not yet paid by the  Company,  and any accrued  vacation pay not yet paid by the
Company; and

                  (ii)  for  a   three-year   period   following   the  Date  of
Termination,  the Company shall continue  benefits to Lamberti and/or Lamberti's
family  at least  equal to those  which  would  have  been  provided  to them in
accordance with the plans, programs,  practices and policies provided under this
Agreement if Lamberti's  employment had not been  terminated,  including  health
insurance and life  insurance,  in  accordance  with the most  favorable  plans,
practices,  programs  or policies  provided by the Company and its  subsidiaries
during the 90-day period  immediately  preceding the Date of Termination  or, if
more favorable to Lamberti,  as in effect at any time thereafter with respect to
other key employees and their families.  Notwithstanding the foregoing, however,
the Company shall continue at all times to offer and provide the above-described
health  insurance  coverages to Lamberti  and his spouse until their  respective
dates of death,  except to the extent  such  coverage  is or  otherwise  becomes
available to Lamberti and his spouse under the Medicare program of benefits.

         (f)  ALTERNATIVE  EXCISE TAX CAP.  Notwithstanding  the  provisions  of
Section 6(e) hereof,  if any payments or benefits  received or to be received by
Lamberti  (whether  pursuant to the terms of this  Agreement  or any other plan,
arrangement or agreement with the Company,  any person whose actions result in a
Change of Control  or any person  affiliated  with the  Company or such  person)
constitute  "parachute payments" within the meaning of Section  280G(b)(2)(A) of
the Code and the value thereof exceeds 2.99 times  Lamberti's  "base amount," as
defined in Section  280G(b)(3) of the Code,  then, in lieu thereof,  the Company
shall pay to Lamberti,  as soon as practicable following the Date of Termination
but in no event later than thirty (30) days thereafter,  a lump sum cash payment
equal to 2.99 times his "base  amount" (the  "Alternative  Severance  Payment"),
reduced as provided  below.  The value of the payments to be made under  Section
6(e) and Lamberti's base amount shall be determined in accordance with temporary
or final  regulations,  if any,  promulgated  under Section 280G of the Code and
based upon the advice of the tax counsel referred to below.

         The Alternative Severance Payment shall be reduced by the amount of any
other payment or the value of any benefit received or to be received by Lamberti
in connection


<PAGE>



with a Change of Control of the Company or his termination of employment  unless
(i)  Lamberti  shall have  effectively  waived his receipt or  enjoyment of such
payment or benefit  prior to the date of  payment of the  Alternative  Severance
Payment,  (ii)  in  the  opinion  of  tax  counsel  selected  by  the  Company's
independent  auditors,  such  other  payment or benefit  does not  constitute  a
"parachute  payment"  within the meaning of Section  280G(b)(2)  of the Code, or
(iii) in the opinion of such tax counsel, the Alternative Severance Payment plus
all other payments or benefits which constitute  "parachute payments" within the
meaning  of  Section  280G(b)(2)  of the Code are  reasonable  compensation  for
services actually rendered within the meaning of Section  280G(b)(4) of the Code
or are otherwise not subject to disallowance as a deduction by reason of Section
280G of the Code. The value of any non-cash  benefit or any deferred  payment or
benefit  shall be  determined  in  accordance  with the  principles  of  Section
280G(d)(3) and (4) of the Code.

         (g) SECTION  162(M)  LIMITATION.  In the event that the payments due to
Lamberti under this Section 6 exceed the "reasonable  compensation"  limitations
of Section 162(m) of the Code, that portion thereof that would not be deductible
by the Company in the taxable year in which the payment is due shall be deferred
by the  Company  and paid to  Lamberti  on the date that is sixteen  (16) months
following the Date of  Termination,  together with interest  thereon at the rate
provided in Section 7872(f)(2) of the Code.

         7.  NON-EXCLUSIVITY OF RIGHTS.  Nothing in this Agreement shall prevent
or limit Lamberti's  continuing or future  participation in any benefit,  bonus,
incentive  or other  plans,  programs,  policies or  practices,  provided by the
Company and for which  Lamberti  may qualify,  including  but not limited to the
SERP,  nor shall  anything  herein  limit or  otherwise  affect  such  rights as
Lamberti  may have under the SERP or any stock option or other  agreements  with
the Company.  Amounts which are vested  benefits or which  Lamberti is otherwise
entitled to receive under any plan,  policy,  practice or program of the Company
at or  subsequent to the Date of  Termination,  including but not limited to the
SERP,  shall be  payable  in  accordance  with the  SERP or such  plan,  policy,
practice or program.

         8. FULL  SETTLEMENT.  The  Company's  obligation  to make the  payments
provided  for in  this  Agreement  and  otherwise  to  perform  its  obligations
hereunder  shall  not be  affected  by any  set-off,  counterclaim,  recoupment,
defense or other  claim,  right or action  which the  Company  may have  against
Lamberti  or others.  In no event  shall  Lamberti  be  obligated  to seek other
employment or take any other action by way of mitigation of the amounts  payable
to Lamberti  under any of the  provisions of this  Agreement,  but such payments
shall be reduced to the extent of Lamberti's other earned income (if any) during
any remaining portion of the Employment Period. Following any Change of Control,
the Company agrees to pay, to the full extent permitted by law, all


<PAGE>



legal fees and expenses which  Lamberti may reasonably  incur as a result of any
contest  (regardless of the outcome thereof) by the Company or others (including
Lamberti)  of the  validity  or  enforceability  of,  or  liability  under,  any
provision of this  Agreement or any guarantee of  performance  thereof,  plus in
each case  interest  at the  applicable  Federal  rate  provided  for in Section
7872(f)(2) of the Code.

         9. RETIREMENT OF LAMBERTI.  It is understood that Lamberti shall retire
on the last day of the  calendar  year during which he reaches  sixty-five  (65)
years of age. The Board of Directors  of the  Company,  at its sole option,  may
offer to extend Lamberti's employment on a year-to-year basis after the calendar
year in which Lamberti  reaches age  sixty-five  (65). At the conclusion of each
year it will be presumed that Lamberti will retire unless the Board of Directors
determines to offer to extend Lamberti's employment for an additional year.

         Following the retirement of Lamberti, the Company shall continue at all
times to offer and  provide  health  insurance  coverages  to  Lamberti  and his
spouse,  in accordance with the most favorable  plans,  programs,  practices and
policies provided by the Company during the 90-day period immediately  preceding
the effective  date of Lamberti's  retirement or, if more favorable to Lamberti,
as in effect at any time  thereafter  with  respect to other key  employees  and
their families, until the death of Lamberti and his spouse, except to the extent
such coverage is or otherwise becomes available to Lamberti and his spouse under
the Medicare program of benefits.

         10.   AVAILABILITY   OF  LAMBERTI  AFTER   RETIREMENT.   Following  his
retirement,  Lamberti  shall at  reasonable  times and  insofar as his  physical
condition may permit, hold himself available at the written request of the Board
of Directors of the Company to consult with and advise the officers,  directors,
and other  representatives of the Company.  Such requests for Lamberti's service
shall,  however,  be  structured  so that  reasonable  allowances  are  made for
Lamberti's needs for vacation time and for other  considerations of his physical
well-being.  All such  services  shall be  provided  by Lamberti at his place of
residence unless otherwise agreed to by Lamberti. Lamberti shall not be required
to devote any  prescribed  hours to  consulting  with and  giving  advice to the
officers,  directors,  and other  representatives  of the Company in order to be
entitled  to the  retirement  benefits  as set out in the  SERP,  but  all  such
benefits shall be considered as earned in return for the consulting  service and
advice that  Lamberti may give from time to time to the Company,  its  officers,
directors, and other representatives.

         If Lamberti's  physical condition shall prevent him from consulting and
advising with the officers,  directors or other  representatives of the Company,
the retirement  benefits  provided  under the SERP shall  nonetheless be paid as
therein provided.

         Lamberti shall be reimbursed by the Company for all reasonable expenses
incurred


<PAGE>



as a consultant  and  advisor,  including  expenses  for travel,  communication,
entertainment  and similar items, upon presentation of itemized accounts of such
expenditures.

         11. DISCRETION OF BOARD OF DIRECTORS. Notwithstanding any other term or
provision of this  Agreement to the contrary,  nothing stated herein is intended
to,  nor  shall  it be  construed,  to  abrogate,  limit,  alter or  affect  the
authority,  rights and  privileges  of the Board of  Directors of the Company to
remove  Lamberti  as Chief  Executive  Officer or  Chairman  of the Board of the
Company,  without Cause,  or during the term of this Agreement to elect as Chief
Executive  Officer or Chairman of the Board of Directors of the Company a person
other than  Lamberti,  as provided  by the laws of the State of Iowa;  provided,
however, it is expressly agreed and understood that, in the event any one or any
combination  of such events occurs,  unless  Lamberti is terminated for Cause as
defined in Section 5(b) hereof,  Lamberti may terminate his  employment for Good
Reason,  in which case the Company shall pay Lamberti the benefits  described in
either  Section  6(d) or  Section  6(e) of this  Agreement,  as  applicable,  in
consideration thereof.

         12.  CONFIDENTIAL  INFORMATION;  RESTRICTIVE  COVENANT.  (a) During the
period of his  employment,  Lamberti  shall hold in  fiduciary  capacity for the
benefit of the Company all secret or confidential information, knowledge or data
relating  to  the  Company  or any of its  subsidiaries,  and  their  respective
businesses,  which  shall  have been  obtained  by  Lamberti  during  Lamberti's
employment by the Company or any of its  subsidiaries  and which shall not be or
become public knowledge  (other than by acts by Lamberti or his  representatives
in  violation  of this  Agreement).  During a three  (3) year  period  following
termination  of  Lamberti's  employment  with the Company,  Lamberti  shall not,
without the prior  written  consent of the Company,  communicate  or divulge any
such  information,  knowledge or data to anyone other than the Company and those
designated by it.

         (b) While this Agreement  remains in effect and Lamberti is entitled to
compensation  or  benefits  pursuant  to Sections 4 through 6 hereof (or, in the
event of termination  of his  employment for Good Reason,  for a period of three
(3) years thereafter), Lamberti shall not directly or indirectly associate with,
participate in or render service to, whether as an employee,  officer, director,
consultant,  independent  contractor  or  otherwise,  any  organization  that is
engaged in business in  competition  with the Company,  and he shall not himself
engage in any such business on his own account.

         (c) In the event of a  demonstrated  breach  of this  Section  12,  the
parties agree that the Company shall be entitled to seek  equitable  relief in a
court of competent  jurisdiction to prevent any anticipated continuing breach of
the terms and  conditions  of this  Section  12 and to  secure  the  enforcement
thereof. The foregoing remedy shall be exclusive and in lieu of any other remedy
otherwise available to the Company under law.

     13. SUCCESSORS.  (a) This Agreement is personal to Lamberti and without the
prior  written  consent  of the  Company  shall not be  assignable  by  Lamberti

shall  inure  to  the  benefit  of  and  be  enforceable  by  Lamberti's   legal

Company  through a Change of Control or  otherwise,  and, (ii) within its lawful
power to do so, any party  effecting or taking  steps to  accomplish a Change of
Control,  to assume  expressly  and agree to perform this  Agreement in the same
manner and to the same extent  that the Company  would be required to perform it
if no such  succession  or Change of Control  had taken  place.  As used in this
Agreement,  "Company"  shall mean the  Company as  hereinbefore  defined and any
successor to its business and/or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law, or otherwise.

     14. MISCELLANEOUS. (a) This Agreement shall be governed by and construed in

Agreement such Federal, state or local taxes as shall be required to be withheld
pursuant to any applicable law or regulation.

         (e)  The  Company's  or  Lamberti's   failure  to  insist  upon  strict
compliance with any provision  hereof shall not be deemed to be a waiver of such
provision or any other provision thereof.

         (f) This Agreement contains the entire understanding of the Company and
Lamberti  with respect to the subject  matter  hereof.  The  Original  Agreement
between Lamberti and the Company,  as defined in the preambles hereof, is hereby

                              AMENDED AND RESTATED
                              EMPLOYMENT AGREEMENT


     THIS AMENDED AND RESTATED  EMPLOYMENT  AGREEMENT (the  "Agreement") is made
and entered  into as of the 24th day of October,  1997,  by and between  Casey's
General Stores,  Inc., an Iowa corporation  (the "Company"),  and Ronald M. Lamb
("Lamb").

         WHEREAS,  the  Board  of  Directors  of  the  Company  (the  "Board  of
Directors") recognizes that the dedication of Lamb as an officer and director to
the affairs and welfare of the Company since its  organization has resulted in a
long and successful association; and

         WHEREAS, the Board of Directors further recognizes that the Company has
grown and prospered as a result of its association with Lamb, and has determined
that it is in the best interests of the Company and its shareholders to preserve
this  association  so as to enable the  Company to further  benefit  from Lamb's
superior  knowledge  and  expertise  in all of its present  and future  business
endeavors; and

         WHEREAS,  the Company and Lamb are parties to an  Employment  Agreement
dated as of  March 2,  1992,  as  amended  by a First  Amendment  to  Employment
Agreement  dated as of January 16, 1997  (together,  the "Original  Agreement"),
providing  for the  employment  of Lamb to  serve  as the  President  and  Chief
Operating  Officer  of the  Company  under the terms  and  conditions  set forth
therein; and

         WHEREAS,  the Board of  Directors  has  further  determined  that it is
appropriate  and in the best  interests of the Company and its  shareholders  to
modify the existing  contractual  arrangements with respect to Lamb's employment
by the  Company,  with the  concurrence  of Lamb,  and to amend and  restate the
Original Agreement to reflect the same; and

         WHEREAS,  the Board of Directors has further  determined  that it is in
the best interest of the Company and its shareholders to assure that the Company
will have the continued  dedication of Lamb,  notwithstanding  the  possibility,
threat or occurrence  of a Change of Control (as defined  below) of the Company,
and to further  encourage  Lamb's full  attention and  dedication to the Company
currently and in the event of any threatened or pending  Change of Control,  and
to provide Lamb with  compensation  arrangements  upon a Change of Control which
provide him with  compensation  for expected  losses that he would suffer in the
event of a Change of Control and which are competitive with those


<PAGE>



of other  corporations,  and,  in  order to  accomplish  these  objectives,  has
determined to cause the Company to enter into this Agreement.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
set forth in this Agreement, the parties hereto agree as follows:

          1.      CERTAIN DEFINITIONS.  For purposes of this Agreement, and in
addition to the other definitions set forth herein, the following terms shall 
have the following meanings:

         a)       "Change of Control" shall mean:

                  (i) the  acquisition  (other  than  from the  Company)  by any
Person (as hereinafter defined), entity or "group" within the meaning of Section
13(d)(3) or  14(d)(2)  of the  Securities  Exchange  Act of 1934 (the  "Exchange
Act"),  (excluding for this purpose, the Company or any employee benefit plan of
the Company,  which acquires  beneficial  ownership of voting  securities of the
Company) of beneficial  ownership  (within the meaning of Rule 13d-3 promulgated
under the  Exchange  Act) of  twenty  percent  (20%) or more of either  the then
outstanding shares of Common Stock, no par value, of the Company or the combined
voting power of the Company's then  outstanding  voting  securities  entitled to
vote  generally  in the election of  directors  (hereinafter  referred to as the
"Common Stock"), unless such beneficial ownership was acquired as a result of an
acquisition  of shares of Common  Stock by the Company  which,  by reducing  the
number of  shares  outstanding,  increases  the  proportionate  number of shares
beneficially owned by such Person,  entity or "group" to twenty percent (20%) or
more of the Common Stock of the Company  then  outstanding;  provided,  however,
that if a Person,  entity or "group" shall become the beneficial owner of twenty
percent  (20%) or more of the Common  Stock of the Company then  outstanding  by
reason of share  purchases by the Company and shall,  after such share purchases
by the Company,  become the beneficial owner of any additional  shares of Common
Stock of the  Company,  then such Person,  entity or "group"  shall be deemed to
have met the conditions hereof; or

                  (ii)  individuals  who, as of the date hereof,  constitute the
Board of Directors (as of the date hereof,  the "Incumbent Board") cease for any
reason to  constitute  at least a majority of the Board of  Directors,  provided
that  any  person  becoming  a  director  subsequent  to the date  hereof  whose
election, or nomination for election by the Company's shareholders, was approved
by a vote of at least a majority of the directors then  comprising the Incumbent
Board  (other than an election or  nomination  of an  individual  whose  initial
assumption  of office is in  connection  with an actual or  threatened  election
contest relating to the election of the directors of the Company,  as such terms
are used in Rule 14a-11 of Regulation  14A  promulgated  under the Exchange Act)
shall be, for purposes of this Agreement considered as though such person were a
member of the


<PAGE>



Incumbent Board; or

                  (iii)  approval  by  the  shareholders  of  the  Company  of a
reorganization,  merger,  consolidation  (in each  case,  with  respect to which
persons  who were the  shareholders  of the  Company  immediately  prior to such
reorganization, merger or consolidation do not, immediately thereafter, own more
than fifty percent (50%) of the combined voting power entitled to vote generally
in  the  election  of  directors  of the  reorganized,  merged  or  consolidated
company's then outstanding voting securities) or a liquidation or dissolution of
the  Company  or of the sale of all or  substantially  all of the  assets of the
Company.

         (b) "Annual Increase" shall take effect on each January 1 for which the
benefit at issue is payable  and shall  mean fifty  percent  (50%) of the annual
increase in the National Consumer Price Index for the City of Des Moines,  Iowa,
as published by the United States Bureau of Labor Statistics.

         (c) "Annual  Bonus" shall mean any bonus  payable at the  discretion of
the Board of Directors  of the Company,  on such terms and in such amounts as it
shall determine.

         (d) "Employment  Period" shall mean the term of Lamb's employment under
this Agreement, as set forth in Section 2 hereof.

         (e)      "Code" shall mean the Internal Revenue Code of 1986, as 
amended.

         (f) "Accrued Obligations" shall mean (i) Lamb's Salary through the Date
of  Termination  at the  rate in  effect  on the Date of  Termination,  (ii) the
product of the Annual  Bonus  paid to Lamb for the last full  fiscal  year and a
fraction,  the  numerator  of which is the number of days in the current  fiscal
year through the Date of  Termination,  and the  denominator of which is 365 and
(iii) any compensation  previously  deferred (together with any accrued interest
thereon)  and not yet paid by the Company and any accrued  vacation  pay not yet
paid by the Company.

         (g) "Person"  shall mean any  individual,  firm,  corporation  or other
entity,  and shall  include  any  successor  (by  merger or  otherwise)  and all
"affiliates" and "associates" of such entity (as those terms are defined in Rule
12b-2 of the General Rules and Regulations under the Exchange Act).

     2.  EMPLOYMENT AND TERM. The Company agrees to employ Lamb, and Lamb agrees
to serve the Company, as Chief Operating Officer and President of the Company on
the terms and under the conditions set forth in this Agreement. The initial term
of employment under this Agreement shall commence on the date hereof and shall

<PAGE>



terminate on April 30, 2000 (the "Initial Term"), after which this Agreement and
the Employment Period hereunder shall be automatically  renewed and extended for
successive  periods of three years  (each of which  shall be a "Renewal  Term"),
subject to the right of the Company and Lamb to terminate this Agreement  during
the  Initial  Term or any such  Renewal  Term in  accordance  with the terms and
conditions  set forth in  subsequent  sections  of this  Agreement,  and further
subject to the right of the  Company  and Lamb to cause this  Agreement  and the
Employment  Period  hereunder  to expire at the end of the  Initial  Term or any
Renewal Term by giving written notice thereof at least one year prior to the end
of the Initial Term or the then current  Renewal Term, as applicable;  provided,
however, that in the event of a Change of Control during the Initial Term or any
Renewal Term, this Agreement and the Employment  Period hereunder  automatically
shall  continue  in full force and effect for the  greater of (i) the  remaining
term of employment  then in progress or (ii) three years from the effective date
of the Change of Control. References herein to the Employment Period shall refer
to both the Initial Term and any successive Renewal Term.

         3. DUTIES OF LAMB.  During the period of his employment in the capacity
of Chief  Operating  Officer and President,  Lamb will perform his duties to the
best of his  ability,  subject to the control of the Board of  Directors.  It is
agreed and understood that the position  (including  status,  office,  title and
reporting requirements), authority, duties and responsibilities of Lamb shall be
substantially the same as those performed by Lamb as Chief Operating Officer and
President  of the  Company  prior to the date of this  Agreement,  and that Lamb
shall at all times serve the best  interests of the Company.  The Company agrees
that Lamb shall at all times have such  authority and  discretion as is required
in the carrying out of Lamb's duties in a proper and efficient  manner,  subject
to review by the Board of Directors.

         During the period of his  employment,  it shall not be a  violation  of
this Agreement for Lamb to (i) serve on corporate, civil or charitable boards or
committees,  (ii) deliver  lectures or fulfill  speaking  engagements  and (iii)
manage personal  investments,  so long as such  activities do not  significantly
interfere with the performance of Lamb's  responsibilities as an employee of the
Company in accordance with this Agreement. It is expressly understood and agreed
that to the extent that any such activities have been conducted by Lamb prior to
the date hereof,  the continued  conduct of such  activities  (or the conduct of
activities  similar in nature and scope  thereto)  subsequent to the date hereof
shall not  thereafter  be deemed to  interfere  with the  performance  of Lamb's
responsibilities to the Company.

     4.  COMPENSATION.  The Company  shall pay to Lamb an annual salary of Three
Hundred  and  Fifty  Thousand  Dollars  ($350,000),  payable  in  equal  monthly
installments,  or such  other  amount as shall be  mutually  agreed  upon by the
Company and Lamb (the "Salary"). In addition, Lamb and/or Lamb's family shall be
entitled to receive

<PAGE>



all  benefits  presently  provided or those  which may  hereafter  be  generally
provided  by the Company to its  employees,  officers  or  directors,  including
health  insurance  and life  insurance.  With  respect to such health  insurance
benefits,  the Company agrees that at all times the health  insurance  coverages
available  to Lamb and his  spouse  under such plans  shall  include  provisions
providing for lifetime  benefits payable on behalf of Lamb and his spouse of not
less than One Million  Dollars  ($1,000,000)  each,  or such other amount as the
Company and Lamb may specifically agree upon in writing,  subject,  however,  to
any  limitations,  restrictions  or  conditions  that shall from time to time be
necessary to satisfy the  requirements  of applicable  federal or state laws and
regulations.

         5.  TERMINATION  OF  EMPLOYMENT.   (a)  Death  or  Disability.   Lamb's
employment under this Agreement shall terminate automatically upon Lamb's death.
If the Company determines in good faith that the Disability of Lamb has occurred
(pursuant to the  definition of  "Disability"  set forth below),  it may give to
Lamb written  notice of its  intention to terminate  Lamb's  employment as Chief
Operating  Officer and  President.  In such event,  Lamb's  employment  with the
Company shall terminate  effective on the thirtieth  (30th) day after receipt of
such notice by Lamb (the "Disability Effective Date"), provided that, within the
thirty (30) days after such  receipt,  Lamb shall not have returned to full-time
performance of his duties.  For purposes of this Agreement,  "Disability"  means
disability or incapacity of Lamb which, at least twenty-six (26) weeks after its
commencement,  is determined by the Board of Directors  upon  competent  medical
advice to be such as to prevent Lamb from  performing  substantially  all of the
duties of Chief Operating Officer and President of the Company.

         (b) Cause. The Company may terminate Lamb's employment for "Cause." For
purposes  of this  Agreement,  "Cause"  means  (i) an act or  acts  of  personal
dishonesty  taken  by Lamb  and  intended  to  result  in  substantial  personal
enrichment of Lamb at the expense of the Company,  (ii)  repeated  violations by
Lamb  of  Lamb's  obligations  under  Section  3 of  this  Agreement  which  are
demonstrably willful and deliberate on Lamb's part and which are not remedied in
a reasonable  period of time after receipt of written notice from the Company or
(iii)  the  conviction  of Lamb of a felony  when such  conviction  is no longer
subject to direct appeal.

         (c)      Good Reason.  Lamb's employment may be terminated by Lamb for 
Good Reason.  For purposes of this Agreement, "Good Reason" means:

                  (i) the assignment to Lamb of any duties  inconsistent  in any
respect with Lamb's position  (including  status,  office,  titles and reporting
requirements),  authority, duties or responsibilities as contemplated by Section
3 of this  Agreement,  or any other  action by the  Company  which  results in a
diminution in such position,  authority,  duties or responsibilities,  excluding
for this purpose an isolated,  insubstantial and inadvertent action not taken in
bad faith and which is remedied by the Company promptly


<PAGE>



after receipt of notice thereof given by Lamb;

                  (ii) Any failure by the Company to comply with the  provisions
of  Section 4 of this  Agreement,  other  than an  isolated,  insubstantial  and
inadvertent  failure  not  occurring  in bad faith and which is  remedied by the
Company promptly after receipt of notice thereof given by Lamb;

                  (iii) the Company's  requiring  Lamb to be based at any office
or location other than the Company's Corporate  Headquarters facility in Ankeny,
Iowa,  except  for  travel  reasonably  required  in the  performance  of Lamb's
responsibilities;

                  (iv)     any purported termination by the Company of Lamb's 
employment otherwise than for death, Disability or Cause as expressly permitted 
by this Agreement; or

                  (v)      any failure by the Company to comply with and satisfy
Section 13(c) of this Agreement.

         For  purposes of this Section  5(c),  any good faith  determination  of
"Good Reason" made by Lamb shall be conclusive.

         (d) Notice of Termination.  Any termination by the Company for Cause or
by Lamb for Good Reason shall be  communicated  by Notice of  Termination to the
other party hereto given in accordance with Section 14(b) of this Agreement. For
purposes of this  Agreement,  a "Notice of  Termination"  means a written notice
which (i) indicates the specific termination  provision in this Agreement relied
upon, (ii) sets forth in reasonable detail the facts and  circumstances  claimed
to provide a basis for termination of Lamb's  employment  under the provision so
indicated and (iii) if the Date of Termination  (as defined below) is other than
the date of receipt of such notice,  specifies the termination  date (which date
shall be not more than fifteen (15) days after the giving of such  notice).  The
failure  of  Lamb  to set  forth  in the  Notice  of  Termination  any  fact  or
circumstance  which  contributes to a showing of Good Reason shall not waive any
right  of  Lamb   hereunder  or  preclude  Lamb  from  asserting  such  fact  or
circumstance in enforcing his rights hereunder.

         (e)  Date of  Termination.  "Date  of  Termination"  means  the date of
receipt of the Notice of Termination or any later date specified therein, as the
case may be; provided,  however,  that (i) if Lamb's employment is terminated by
the Company other than for Cause or Disability, the Date of Termination shall be
the date on which the  Company  notifies  Lamb of such  termination  and (ii) if
Lamb's  employment is terminated by reason of death or  Disability,  the Date of
Termination shall be the date of death of Lamb or the Disability Effective Date,
as the case may be.

         6. OBLIGATIONS OF THE COMPANY UPON TERMINATION OF EMPLOYMENT. (a) Death
of Lamb.  In the event of the death of Lamb during the term hereof,  the Company
shall pay to Lamb's spouse,  commencing on the first day of the month  following
his death and  continuing for a period of  twenty-four  (24) months  thereafter,
benefits equal to the monthly  installments  of Salary which was then being paid
to Lamb  pursuant  to  Section 4 herein.  Immediately  following  such  two-year
period,  the Company  shall  commence the payment of monthly  benefits to Lamb's
spouse equal in amount to one-fourth (1/4) of the monthly installments of Salary
which was being  paid to Lamb at the time of his death  under  Section 4 herein,
which monthly  benefits shall be paid for a period of twenty (20) years or until
the death of Lamb's spouse,  whichever  occurs first.  In addition,  the Company
shall  continue at all times to offer and provide health  insurance  coverage to
Lamb's spouse,  in accordance with the plans,  programs,  practices and policies
provided by the Company under the terms of this  Agreement at the time of Lamb's
death,  until the death of Lamb's spouse,  except to the extent such coverage is
or otherwise  becomes  available to Lamb's spouse under the Medicare  program of
benefits.

         (b) Disability of Lamb. If Lamb's employment is terminated by reason of
the Disability of Lamb,  Lamb's  employment under this Agreement shall terminate
without further  obligations to Lamb,  other than those  obligations  accrued or
earned  and  vested  (if  applicable)  by  Lamb as of the  Date of  Termination,
including for this purpose,  all Accrued Obligations and those set forth herein.
All such Accrued  Obligations shall be paid to Lamb in a lump sum in cash within
thirty (30) days of the Date of  Termination.  Anything in this Agreement to the
contrary notwithstanding,  Lamb shall be entitled after the Disability Effective
Date to receive  disability  and other  benefits in an amount  equal to one-half
(1/2) of his  Salary  (adjusted  on an annual  basis by the amount of the Annual
Increase),  which shall be payable in equal monthly installments until the close
of the calendar year during which Lamb attains  sixty-five  (65) years of age or
until  the last day of the  month in which  Lamb is no  longer  deemed  disabled
pursuant to this Agreement, or until Lamb's death, whichever shall first occur.

         If Lamb  shall  receive  any  disability  payments  from any  insurance
policies  paid  for by the  Company,  the  payments  to  Lamb  pursuant  to this
provision shall be reduced by the amount of disability payments received by Lamb
under any such insurance policy or policies.

         If,  following  the  termination  of  Lamb's  employment  by  reason of
Disability,  the Board of Directors  determines,  upon competent medical advice,
that  Lamb  is  no  longer   prevented  by  said   Disability   from  performing
substantially  all of the duties as Chief Operating Officer and President of the
Company,  the Company  shall give Lamb not less than  thirty  (30) days  written
notice of its  election  to cease the  payment  of  Disability  benefits  to him
pursuant to this Section 6(b), following which (i) the Company shall have


<PAGE>



no further  obligations  to Lamb to make said  Disability  payments  as provided
herein and (ii) Lamb  thereafter  shall be entitled to retire and  terminate his
employment  with the Company,  without further action or notice on his part, and
to receive the benefits payable under the Non-Qualified  Supplemental  Executive
Retirement  Plan of the Company (the "SERP") (or any successor  plan), as and to
the extent set forth therein,  and shall hold himself  available to the Board of
Directors for consultation as provided in Section 10 hereof.

         Notwithstanding  any  Disability on the part of Lamb, the Company shall
continue at all times to offer and provide  health  insurance  coverages to Lamb
and his spouse, in accordance with the most favorable plans, programs, practices
and  policies  provided  by the  Company  during the 90-day  period  immediately
preceding the  Disability  Effective  Date or, if more  favorable to Lamb, as in
effect at any time  thereafter  with  respect to other key  employees  and their
families,  until the death of Lamb and his  spouse,  except to the  extent  such
coverage is or  otherwise  becomes  available  to Lamb and his spouse  under the
Medicare program of benefits.

         (c) Cause;  Other than for Good Reason.  If Lamb's  employment shall be
terminated for Cause,  Lamb's  employment  under this Agreement  shall terminate
without  further  obligations  to Lamb (other than the obligation to pay to Lamb
his Salary through the Date of Termination  plus the amount of any  compensation
previously  deferred by Lamb,  together with accrued interest thereon).  If Lamb
terminates employment other than for Good Reason, this Agreement shall terminate
without further  obligations to Lamb,  other than those  obligations  accrued or
earned and vested  (if  applicable)  by Lamb  through  the Date of  Termination,
including  for  this  purpose,  all  Accrued   Obligations.   All  such  Accrued
Obligations  shall be paid to Lamb in a lump sum in cash within thirty (30) days
of the Date of Termination.

         (d) Good  Reason;  Other than for Cause or  Disability.  If the Company
shall terminate Lamb's employment other than for Cause, Disability,  or death or
if Lamb shall  terminate his  employment  for Good Reason at any time during the
Employment  Period,  except during a three-year  period  following any Change of
Control (in which case the provisions of Section 6(e) shall apply), then in such
event:

                  (i) the Company shall pay to Lamb in a lump sum in cash within
thirty (30) days after the Date of  Termination  the  aggregate of the following
amounts:

                           A.       to the extent not theretofore paid, Lamb's 
Salary through the Date of Termination; and

                           B.       the product of (x) the highest Annual Bonus 
paid to Lamb during the three (3) fiscal years preceding the fiscal year in 
which the Date of


<PAGE>



Termination  occurs (the "Recent  Bonus") and (y) a fraction,  the  numerator of
which is the  number of days in the  current  fiscal  year  through  the date of
Termination and the denominator of which is 365; and

                           C.       the product of (x) two (2.0) and (y) the sum
of (i) the Salary and (ii) the Recent Bonus; and

                           D.       in the case of compensation previously 
deferred by Lamb, all amounts previously deferred (together with any accrued 
interest thereon) and not yet  paid by the  Company,  and any  accrued  vacation
pay not yet  paid by the Company; and

                  (ii) for a two-year period  following the Date of Termination,
the Company shall continue  benefits to Lamb and/or Lamb's family at least equal
to those which would have been  provided to them in  accordance  with the plans,
programs,  practices  and  policies  provided  under  this  Agreement  if Lamb's
employment  had  not  been  terminated,  including  health  insurance  and  life
insurance, in accordance with the most favorable plans,  practices,  programs or
policies  provided by the Company and its subsidiaries  during the 90-day period
immediately  preceding the Date of Termination or, if more favorable to Lamb, as
in effect at any time  thereafter  with respect to other key employees and their
families.  Notwithstanding the foregoing, however, the Company shall continue at
all times to offer and provide the above-described health insurance coverages to
Lamb and his spouse until their respective dates of death,  except to the extent
such coverage is or otherwise becomes available to Lamb and his spouse under the
Medicare program of benefits.

         (e) Good Reason; Other than for Cause or Disability, following a Change
of Control.  If, during a three year period following any Change of Control, the
Company shall terminate Lamb's employment other than for Cause,  Disability,  or
death or if Lamb shall terminate his employment for Good Reason:

                  (i) the Company shall pay to Lamb in a lump sum in cash on the
thirtieth  (30th) day  following  the Date of  Termination  the aggregate of the
following amounts:

           A.       to the extent not theretofore paid, Lamb's 
Salary through the Date of Termination; and

           B.       the product of (x) the Recent Bonus and (y) 
a fraction, the numerator of which is the number of days in the current fiscal 
year through the date of Termination and the denominator of which is 365; and

           C.       the product of (x) three (3.0) and (y) the sum of (i) the 
Salary


<PAGE>



                  and (ii) the Recent Bonus; and

            D.       in the case of compensation previously deferred by Lamb, 
all amounts previously deferred (together with any accrued interest thereon) 
and not yet  paid by the  Company,  and any  accrued  vacation  pay not yet 
paid by the Company; and

                  (ii)  for  a   three-year   period   following   the  Date  of
Termination, the Company shall continue benefits to Lamb and/or Lamb's family at
least equal to those which would have been provided to them in  accordance  with
the plans,  programs,  practices and policies  provided  under this Agreement if
Lamb's  employment had not been terminated,  including health insurance and life
insurance, in accordance with the most favorable plans,  practices,  programs or
policies  provided by the Company and its subsidiaries  during the 90-day period
immediately  preceding the Date of Termination or, if more favorable to Lamb, as
in effect at any time  thereafter  with respect to other key employees and their
families.  Notwithstanding the foregoing, however, the Company shall continue at
all times to offer and provide the above-described health insurance coverages to
Lamb and his spouse until their respective dates of death,  except to the extent
such coverage is or otherwise becomes available to Lamb and his spouse under the
Medicare program of benefits.

         (f)  Alternative  Excise Tax Cap.  Notwithstanding  the  provisions  of
Section 6(e) hereof,  if any payments or benefits  received or to be received by
Lamb  (whether  pursuant  to the  terms of this  Agreement  or any  other  plan,
arrangement or agreement with the Company,  any person whose actions result in a
Change of Control  or any person  affiliated  with the  Company or such  person)
constitute  "parachute payments" within the meaning of Section  280G(b)(2)(A) of
the Code and the value  thereof  exceeds  2.99 times  Lamb's  "base  amount," as
defined in Section  280G(b)(3) of the Code,  then, in lieu thereof,  the Company
shall pay to Lamb, as soon as practicable  following the Date of Termination but
in no event  later than  thirty (30) days  thereafter,  a lump sum cash  payment
equal to 2.99 times his "base  amount" (the  "Alternative  Severance  Payment"),
reduced as provided  below.  The value of the payments to be made under  Section
6(e) and Lamb's base amount shall be determined in accordance  with temporary or
final regulations,  if any, promulgated under Section 280G of the Code and based
upon the advice of the tax counsel referred to below.

         The Alternative Severance Payment shall be reduced by the amount of any
other payment or the value of any benefit  received or to be received by Lamb in
connection  with a Change  of  Control  of the  Company  or his  termination  of
employment  unless  (i) Lamb  shall  have  effectively  waived  his  receipt  or
enjoyment  of such  payment  or  benefit  prior  to the date of  payment  of the
Alternative  Severance  Payment,  (ii) in the opinion of tax counsel selected by
the  Company's  independent  auditors,  such other  payment or benefit  does not
constitute a "parachute payment" within the meaning of Section


<PAGE>



280G(b)(2)  of the  Code,  or (iii) in the  opinion  of such  tax  counsel,  the
Alternative  Severance  Payment  plus  all  other  payments  or  benefits  which
constitute  "parachute payments" within the meaning of Section 280G(b)(2) of the
Code are  reasonable  compensation  for services  actually  rendered  within the
meaning  of  Section  280G(b)(4)  of the Code or are  otherwise  not  subject to
disallowance  as a deduction by reason of Section 280G of the Code. The value of
any non-cash  benefit or any deferred  payment or benefit shall be determined in
accordance with the principles of Section 280G(d)(3) and (4) of the Code.

         (g) Section  162(m)  Limitation.  In the event that the payments due to
Lamb under this Section 6 exceed the  "reasonable  compensation"  limitations of
Section 162(m) of the Code, that portion thereof that would not be deductible by
the Company in the taxable year in which the payment is due shall be deferred by
the Company and paid to Lamb on the date that is sixteen  (16) months  following
the Date of Termination,  together with interest thereon at the rate provided in
Section 7872(f)(2) of the Code.

         7.  NON-EXCLUSIVITY OF RIGHTS.  Nothing in this Agreement shall prevent
or limit  Lamb's  continuing  or future  participation  in any  benefit,  bonus,
incentive  or other  plans,  programs,  policies or  practices,  provided by the
Company and for which Lamb may qualify,  including  but not limited to the SERP,
nor shall anything herein limit or otherwise affect such rights as Lamb may have
under the SERP or any stock option or other agreements with the Company. Amounts
which are vested  benefits or which Lamb is otherwise  entitled to receive under
any plan,  policy,  practice or program of the Company at or  subsequent  to the
Date of Termination,  including but not limited to the SERP, shall be payable in
accordance with the SERP or such plan, policy, practice or program.

         8. FULL  SETTLEMENT.  The  Company's  obligation  to make the  payments
provided  for in  this  Agreement  and  otherwise  to  perform  its  obligations
hereunder  shall  not be  affected  by any  set-off,  counterclaim,  recoupment,
defense or other claim,  right or action which the Company may have against Lamb
or others.  In no event shall Lamb be obligated to seek other employment or take
any other action by way of mitigation  of the amounts  payable to Lamb under any
of the provisions of this  Agreement,  but such payments shall be reduced to the
extent of Lamb's other earned  income (if any) during any  remaining  portion of
the Employment  Period.  Following any Change of Control,  the Company agrees to
pay, to the full extent permitted by law, all legal fees and expenses which Lamb
may  reasonably  incur as a result of any  contest  (regardless  of the  outcome
thereof)  by  the  Company  or  others  (including  Lamb)  of  the  validity  or
enforceability  of, or liability  under,  any provision of this Agreement or any
guarantee of performance  thereof,  plus in each case interest at the applicable
Federal rate provided for in Section 7872(f)(2) of the Code.



<PAGE>



         9.  RETIREMENT OF LAMB. It is understood  that Lamb shall retire on the
last day of the calendar year during which he reaches  sixty-five  (65) years of
age. The Board of Directors  of the  Company,  at its sole option,  may offer to
extend  Lamb's  employment  on a  year-to-year  basis after the calendar year in
which Lamb reaches age  sixty-five  (65). At the conclusion of each year it will
be presumed  that Lamb will retire  unless the Board of Directors  determines to
offer to extend Lamb's employment for an additional year.

         Following  the  retirement of Lamb,  the Company shall  continue at all
times to offer and provide health insurance coverages to Lamb and his spouse, in
accordance  with the most  favorable  plans,  programs,  practices  and policies
provided by the  Company  during the 90-day  period  immediately  preceding  the
effective date of Lamb's  retirement or, if more favorable to Lamb, as in effect
at any time  thereafter  with respect to other key employees and their families,
until the death of Lamb and his spouse, except to the extent such coverage is or
otherwise becomes available to Lamb and his spouse under the Medicare program of
benefits.

         10.  AVAILABILITY OF LAMB AFTER  RETIREMENT.  Following his retirement,
Lamb shall at reasonable times and insofar as his physical condition may permit,
hold himself  available at the written  request of the Board of Directors of the
Company  to  consult  with  and  advise  the  officers,   directors,  and  other
representatives of the Company. Such requests for Lamb's service shall, however,
be  structured  so that  reasonable  allowances  are made for  Lamb's  needs for
vacation time and for other considerations of his physical well-being.  All such
services  shall be provided by Lamb at his place of residence  unless  otherwise
agreed to by Lamb. Lamb shall not be required to devote any prescribed  hours to
consulting  with  and  giving  advice  to the  officers,  directors,  and  other
representatives  of the  Company  in  order  to be  entitled  to the  retirement
benefits as set out in the SERP,  but all such  benefits  shall be considered as
earned in return for the  consulting  service and advice that Lamb may give from
time to time to the Company, its officers, directors, and other representatives.

         If Lamb's  physical  condition  shall prevent him from  consulting  and
advising with the officers,  directors or other  representatives of the Company,
the retirement  benefits  provided  under the SERP shall  nonetheless be paid as
therein provided.

         Lamb shall be  reimbursed  by the Company for all  reasonable  expenses
incurred  as  a  consultant   and  advisor,   including   expenses  for  travel,
communication,  entertainment  and similar items,  upon presentation of itemized
accounts of such expenditures.

     11.  DISCRETION  OF BOARD OF DIRECTORS.  Notwithstanding  any other term or
provision of this  Agreement to the contrary,  nothing stated herein is intended
to,  nor  shall  it be  construed,  to  abrogate,  limit,  alter or  affect  the
authority, rights and

<PAGE>



privileges  of the Board of  Directors  of the  Company to remove  Lamb as Chief
Operating  Officer and President of the Company,  without  Cause,  or during the
term of this Agreement to elect as Chief Operating  Officer and President of the
Company a person other than Lamb,  as provided by the laws of the State of Iowa;
provided,  however,  it is expressly agreed and understood that in the event any
one or any  combination  of such events  occurs,  unless Lamb is terminated  for
Cause as defined in Section 5(b) hereof,  Lamb may terminate his  employment for
Good Reason, in which case the Company shall pay Lamb the benefits  described in
either  Section  6(d) or  Section  6(e) of this  Agreement,  as  applicable,  in
consideration thereof.

         12.  CONFIDENTIAL  INFORMATION;  RESTRICTIVE  COVENANT.  (a) During the
period of his employment,  Lamb shall hold in fiduciary capacity for the benefit
of the  Company  all  secret  or  confidential  information,  knowledge  or data
relating  to  the  Company  or any of its  subsidiaries,  and  their  respective
businesses,  which shall have been obtained by Lamb during Lamb's  employment by
the Company or any of its  subsidiaries  and which shall not be or become public
knowledge  (other than by acts by Lamb or his  representatives  in  violation of
this Agreement).  During a three (3) year period following termination of Lamb's
employment with the Company,  Lamb shall not,  without the prior written consent
of the Company,  communicate or divulge any such information,  knowledge or data
to anyone other than the Company and those designated by it.

         (b) While this  Agreement  remains in effect  and Lamb is  entitled  to
compensation  or  benefits  pursuant  to Sections 4 through 6 hereof (or, in the
event of termination  of his  employment for Good Reason,  for a period of three
(3) years  thereafter),  Lamb shall not directly or indirectly  associate  with,
participate in or render service to, whether as an employee,  officer, director,
consultant,  independent  contractor  or  otherwise,  any  organization  that is
engaged in business in  competition  with the Company,  and he shall not himself
engage in any such business on his own account.

         (c) In the event of a  demonstrated  breach  of this  Section  12,  the
parties agree that the Company shall be entitled to seek  equitable  relief in a
court of competent  jurisdiction to prevent any anticipated continuing breach of
the terms and  conditions  of this  Section  12 and to  secure  the  enforcement
thereof. The foregoing remedy shall be exclusive and in lieu of any other remedy
otherwise available to the Company under law.

     13.  SUCCESSORS.  (a) This  Agreement  is  personal to Lamb and without the
prior written  consent of the Company shall not be assignable by Lamb  otherwise
than by will or the laws of descent and distribution. This Agreement shall inure
to the benefit of and be enforceable by Lamb's legal representatives.

         (b)      This Agreement shall inure to the benefit of and be binding 
upon the 

<PAGE>



Company and its successors and assigns.

         (c) The Company  agrees and  covenants to require (i) any  successor or
assignee  (whether direct or indirect,  by purchase,  merger,  consolidation  or
otherwise)  to all or  substantially  all of the business  and/or  assets of the
Company  through a Change of Control or  otherwise,  and, (ii) within its lawful
power to do so, any party  effecting or taking  steps to  accomplish a Change of
Control,  to assume  expressly  and agree to perform this  Agreement in the same
manner and to the same extent  that the Company  would be required to perform it
if no such  succession  or Change of Control  had taken  place.  As used in this
Agreement,  "Company"  shall mean the  Company as  hereinbefore  defined and any
successor to its business and/or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law, or otherwise.

     14. MISCELLANEOUS. (a) This Agreement shall be governed by and construed in
accordance with the laws of the State of Iowa,  without  reference to principles
of  conflict  of  laws.  The  captions  of this  Agreement  are not  part of the
provisions  hereof and shall have no force or effect.  This Agreement may not be
amended  or  modified  otherwise  than by a written  agreement  executed  by the
parties hereto or their respective successors and legal representatives.

         (b) All notices and other communications  hereunder shall be in writing
and shall be given by hand  delivery  to the  other  party or by  registered  or
certified mail, return receipt requested, postage prepaid, addressed as follows:
If the Company, to Casey's General Stores, Inc., P. O. Box 3001, One Convenience
Blvd., Ankeny, Iowa 50021, Attention:  President; and if to Lamb, to his address
appearing on the books of the  Company,  or to his  residence,  or to such other
address  as  either  party  shall  have  furnished  to the other in  writing  in
accordance herewith.  Notice and communications shall be effective when actually
received by the addressee.

         (c)  The  invalidity  or  unenforceability  of any  provision  of  this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement.

         (d) The  Company  may  withhold  from any  amounts  payable  under this
Agreement such Federal, state or local taxes as shall be required to be withheld
pursuant to any applicable law or regulation.

         (e) The  Company's or Lamb's  failure to insist upon strict  compliance
with any provision  hereof shall not be deemed to be a waiver of such  provision
or any other provision thereof.

         (f) This  Agreement  contains the entire  understanding  of the 
Company and Lamb with respect to the subject matter hereof.  The Original 
Agreement between Lamb

<PAGE>



and the Company,  as defined in the preambles  hereof,  is hereby terminated and
shall be of no further force or effect.

         (g) No change,  amendment or  modification  of this Agreement  shall be
valid unless the same be in writing and signed by the Company and Lamb.

         (h) This Agreement may be executed in any number of counterparts,  each
of which shall be deemed to be an original and all of which taken together shall
constitute one and the same  instrument with the same force and effect as if all
the parties had executed the same document.

         IN WITNESS WHEREOF,  the respective  parties have caused this Agreement
to be executed as of the day and year first above written.

                              AMENDED AND RESTATED
                              EMPLOYMENT AGREEMENT


     THIS AMENDED AND RESTATED  EMPLOYMENT  AGREEMENT (the  "Agreement") is made
and entered  into as of the 24th day of October,  1997,  by and between  Casey's
General Stores, Inc., an Iowa corporation (the "Company"),  and Douglas K. Shull
("Shull").

         WHEREAS,  the  Board  of  Directors  of  the  Company  (the  "Board  of
Directors")  recognizes  that the dedication of Shull as an officer and director
to the affairs and welfare of the Company has resulted in a long and  successful
association; and

         WHEREAS, the Board of Directors further recognizes that the Company has
grown  and  prospered  as a  result  of its  association  with  Shull,  and  has
determined that it is in the best interests of the Company and its  shareholders
to preserve this association so as to enable the Company to further benefit from
Shull's  superior  knowledge  and  expertise  in all of its  present  and future
business endeavors; and

         WHEREAS,  the Company and Shull are parties to an Employment  Agreement
dated as of  March 2,  1992,  as  amended  by a First  Amendment  to  Employment
Agreement  date as of  January 9, 1997  (together,  the  "Original  Agreement"),
providing  for the  employment of Shull to serve as the Treasurer of the Company
under the terms and conditions set forth therein; and

         WHEREAS,  the Board of  Directors  has  further  determined  that it is
appropriate  and in the best  interests of the Company and its  shareholders  to
modify the existing contractual  arrangements with respect to Shull's employment
by the  Company,  with the  concurrence  of Shull,  and to amend and restate the
Original Agreement to reflect the same; and

         WHEREAS,  the Board of Directors has further  determined  that it is in
the best interest of the Company and its shareholders to assure that the Company
will have the continued  dedication of Shull,  notwithstanding  the possibility,
threat or occurrence  of a Change of Control (as defined  below) of the Company,
and to further  encourage  Shull's full  attention and dedication to the Company
currently and in the event of any threatened or pending  Change of Control,  and
to provide Shull with  compensation  arrangements upon a Change of Control which
provide him with  compensation  for expected  losses that he would suffer in the
event of a Change  of  Control  and which are  competitive  with  those of other
corporations, and, in order to accomplish these objectives, has determined to


<PAGE>



cause the Company to enter into this Agreement.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
set forth in this Agreement, the parties hereto agree as follows:

     1. CERTAIN DEFINITIONS.  For purposes of this Agreement, and in addition to
the other  definitions  set forth  herein,  the  following  terms shall have the
following meanings:

the Company,  which acquires  beneficial  ownership of voting  securities of the
Company) of beneficial  ownership  (within the meaning of Rule 13d-3 promulgated

outstanding shares of Common Stock, no par value, of the Company or the combined
voting power of the Company's then  outstanding  voting  securities  entitled to
vote  generally  in the election of  directors  (hereinafter  referred to as the
"Common Stock"), unless such beneficial ownership was acquired as a result of an
acquisition  of shares of Common  Stock by the Company  which,  by reducing  the
number of  shares  outstanding,  increases  the  proportionate  number of shares
beneficially owned by such Person,  entity or "group" to twenty percent (20%) or
more of the Common Stock of the Company  then  outstanding;  provided,  however,
that if a Person,  entity or "group" shall become the beneficial owner of twenty
percent  (20%) or more of the Common  Stock of the Company then  outstanding  by
reason of share  purchases by the Company and shall,  after such share purchases
by the Company,  become the beneficial owner of any additional  shares of Common
Stock of the  Company,  then such Person,  entity or "group"  shall be deemed to
have met the conditions hereof; or

                  (ii)  individuals  who, as of the date hereof,  constitute the
Board of Directors (as of the date hereof,  the "Incumbent Board") cease for any

that  any  person  becoming  a  director  subsequent  to the date  hereof  whose
election, or nomination for election by the Company's shareholders, was approved
by a vote of at least a majority of the directors then  comprising the Incumbent
Board  (other than an election or  nomination  of an  individual  whose  initial
assumption  of office is in  connection  with an actual or  threatened  election
contest relating to the election of the directors of the Company,  as such terms
are used in Rule 14a-11 of Regulation  14A  promulgated  under the Exchange Act)
shall be, for purposes of this Agreement considered as though such person were a
member of the Incumbent Board; or


<PAGE>



                  (iii)  approval  by  the  shareholders  of  the  Company  of a
reorganization,  merger,  consolidation  (in each  case,  with  respect to which
persons  who were the  shareholders  of the  Company  immediately  prior to such
reorganization, merger or consolidation do not, immediately thereafter, own more
than fifty percent (50%) of the combined voting power entitled to vote generally
in  the  election  of  directors  of the  reorganized,  merged  or  consolidated
company's then outstanding voting securities) or a liquidation or dissolution of
the  Company  or of the sale of all or  substantially  all of the  assets of the
Company.

         (b) "Annual Increase" shall take effect on each January 1 for which the

increase in the National Consumer Price Index for the City of Des Moines,  Iowa,
as published by the United States Bureau of Labor Statistics.

         (c) "Annual  Bonus" shall mean any bonus  payable at the  discretion of
the Board of Directors  of the Company,  on such terms and in such amounts as it
shall determine.

         (d) "Employment Period" shall mean the term of Shull's employment under
this Agreement, as set forth in Section 2 hereof.

         (e)      "Code" shall mean the Internal Revenue Code of 1986, as 
amended.

         (f) "Accrued  Obligations"  shall mean (i) Shull's  Salary  through the
Date of Termination at the rate in effect on the Date of  Termination,  (ii) the
product of the Annual  Bonus paid to Shull for the last full  fiscal  year and a
fraction,  the  numerator  of which is the number of days in the current  fiscal
year through the Date of  Termination,  and the  denominator of which is 365 and
(iii) any compensation  previously  deferred (together with any accrued interest
thereon)  and not yet paid by the Company and any accrued  vacation  pay not yet
paid by the Company.

         (g) "Person"  shall mean any  individual,  firm,  corporation  or other
entity,  and shall  include  any  successor  (by  merger or  otherwise)  and all
"affiliates" and "associates" of such entity (as those terms are defined in Rule
12b-2 of the General Rules and Regulations under the Exchange Act).

         2.  EMPLOYMENT AND TERM. The Company agrees to employ Shull,  and Shull
agrees to serve the Company,  as Treasurer of the Company  until August 1, 2001,
unless his  employment  is otherwise  terminated as provided  herein;  provided,
however,  that  in the  event  of a  Change  of  Control  during  the  foregoing
Employment Period, this Agreement shall continue in full force and effect for an
additional  period of three (3) years following the expiration of the Employment
Period (until August 1, 2004).


<PAGE>



          3.  DUTIES OF  SHULL.  During  the  period  of his  employment  in the
capacity of Treasurer,  Shull agrees to devote all professional skill and energy
to the faithful and full  satisfaction of his duties as Treasurer.  It is agreed
and understood  that Shull will perform all duties  assigned to him, which shall
be  substantially  the same as those  performed  by  Shull as  Treasurer  of the
Company prior to the date of this Agreement (including status,  offices,  titles
and reporting requirements), to the full satisfaction of the Board of Directors.
The Company  agrees that Shull shall have such  authority  and  discretion as is
necessary to fully and  faithfully  perform his duties in a proper and efficient
manner, subject to review by the Board of Directors.

         During the period of his  employment,  it shall not be a  violation  of
this Agreement for Shull to (i) serve on corporate,  civil or charitable  boards
or committees,  (ii) deliver lectures or fulfill speaking  engagements and (iii)
manage personal  investments,  so long as such  activities do not  significantly
interfere with the performance of Shull's responsibilities as an employee of the
Company in accordance with this Agreement. It is expressly understood and agreed
that to the extent that any such  activities  have been conducted by Shull prior
to the date hereof,  the continued conduct of such activities (or the conduct of
activities  similar in nature and scope  thereto)  subsequent to the date hereof
shall not  thereafter  be deemed to interfere  with the  performance  of Shull's
responsibilities to the Company.

         4. COMPENSATION. The Company shall pay to Shull an annual salary of One
Hundred  Forty-Five  Thousand  Dollars  ($145,000),  payable  in  equal  monthly
installments,  or such  other  amount as shall be  mutually  agreed  upon by the
Company and Shull (the "Salary"). In addition, Shull and/or Shull's family shall
be  entitled  to receive  all  benefits  presently  provided  or those which may
hereafter  be provided  generally by the Company to its  employees,  officers or
directors,  including health insurance and life insurance.  With respect to such
health  insurance  benefits,  the  Company  agrees  that at all times the health
insurance  coverages  available  to Shull and his spouse  under such plans shall
include  provisions  providing for lifetime  benefits payable on behalf of Shull
and his spouse of not less than One Million Dollars  ($1,000,000)  each, or such
other  amount as the Company and Shull may  specifically  agree upon in writing,
subject, however, to any limitations, restrictions or conditions that shall from
time to time be necessary to satisfy the  requirements of applicable  federal or
state laws and regulations.

         5.  TERMINATION  OF  EMPLOYMENT.  (a)  Death  or  Disability.   Shull's
employment  under this  Agreement  shall  terminate  automatically  upon Shull's
death. If the Company  determines in good faith that the Disability of Shull has
occurred  (pursuant to the definition of "Disability"  set forth below),  it may
give to Shull written notice of its intention to terminate Shull's employment as
Treasurer of the Company.  In such event,  Shull's  employment  with the Company
shall  terminate  effective on the  thirtieth  (30th) day after  receipt of such
notice by Shull (the "Disability Effective Date"), provided that,


<PAGE>



within the thirty (30) days after such receipt, Shull shall not have returned to
full-time performance of his duties. For purposes of this Agreement, "Disability
means  disability or incapacity of Shull which,  at least  twenty-six (26) weeks
after its  commencement,  is determined by the Board of Directors upon competent
medical advice to be such as to prevent Shull from performing  substantially all
of the duties as Treasurer of the Company.

         Notwithstanding  any Disability on the part of Shull, the Company shall
continue at all times to offer and provide health  insurance  coverages to Shull
and his spouse, in accordance with the plans,  programs,  practices and policies
provided by the  Company  during the 90-day  period  immediately  preceding  the
Disability  Effective Date or, if more  favorable to Shull,  as in effect at any
time thereafter  with respect to other key employees and their  families,  until
the death of Shull and his  spouse,  except to the extent  such  coverage  is or
otherwise  becomes  available to Shull and his spouse under the Medicare program
of benefits.

         (b) Cause.  The Company may terminate  Shull's  employment for "Cause."
For  purposes of this  Agreement,  "Cause"  means (i) an act or acts of personal
dishonesty  taken by Shull  and  intended  to  result  in  substantial  personal
enrichment of Shull at the expense of the Company,  (ii) repeated  violations by
Shull of  Shull's  obligations  under  Section  3 of this  Agreement  which  are
demonstratively  willful  and  deliberate  on  Shull's  part and  which  are not
remedied in a reasonable period of time after receipt of written notice from the
Company or (iii) the conviction of Shull of a felony when such  conviction is no
longer subject to direct appeal.

         (c)      Good Reason.  Shull's employment may be terminated by Shull 
for Good Reason.  For purposes of this Agreement, "Good Reason" means:

                  (i) the assignment to Shull of any duties  inconsistent in any
respect with Shull's position  (including status,  office,  titles and reporting
requirements),  authority, duties or responsibilities as contemplated by Section
3 of this  Agreement,  or any other  action by the  Company  which  results in a
diminution in such position,  authority,  duties or responsibilities,  excluding
for this purpose an isolated,  insubstantial and inadvertent action not taken in
bad faith and which is remedied by the Company  promptly after receipt of notice
thereof given by Shull;

                  (ii) Any failure by the Company to comply with the  provisions
of  Section 4 of this  Agreement,  other  than an  isolated,  insubstantial  and
inadvertent  failure  not  occurring  in bad faith and which is  remedied by the
Company promptly after receipt of notice thereof given by Shull;

                  (iii)    the Company's requiring Shull to be based at any 
office or location


<PAGE>



         other than the  Company's  Corporate  Headquarters  facility in Ankeny,
Iowa,  except for  travel  reasonably  required  in the  performance  of Shull's
responsibilities;

                  (iv)     any purported termination by the Company of Shull's 
employment otherwise than for death, Disability or Cause as expressly permitted 
by this Agreement; or

                  (v)      any failure by the Company to comply with and satisfy
Section 13(c) of this Agreement.

         For  purposes of this Section  5(c),  any good faith  determination  of
"Good Reason" made by Shull shall be conclusive.

         (d) Notice of Termination.  Any termination by the Company for Cause or
by Shull for Good Reason shall be  communicated  by Notice of Termination to the
other party hereto given in accordance with Section 14(b) of this Agreement. For
purposes of this  Agreement,  a "Notice of  Termination"  means a written notice
which (i) indicates the specific termination  provision in this Agreement relied
upon, (ii) sets forth in reasonable detail the facts and  circumstances  claimed
to provide a basis for termination of Shull's  employment under the provision so
indicated and (iii) if the Date of Termination  (as defined below) is other than
the date of receipt of such notice,  specifies the termination  date (which date
shall be not more than fifteen (15) days after the giving of such  notice).  The
failure  by  Shull  to set  forth  in the  Notice  of  Termination  any  fact or
circumstance  which  contributes to a showing of Good Reason shall not waive any
right  of  Shull  hereunder  or  preclude  Shull  from  asserting  such  fact or
circumstance in enforcing his rights hereunder.

         (e)  Date of  Termination.  "Date  of  Termination"  means  the date of
receipt of the Notice of Termination or any later date specified therein, as the
case may be; provided,  however, that (i) if Shull's employment is terminated by
the Company other than for Cause or Disability, the Date of Termination shall be
the date on which the Company  notifies  Shull of such  termination  and (ii) if
Shull's  employment is terminated by reason of death or Disability,  the Date of
Termination  shall be the date of  death  of Shull or the  Disability  Effective
Date, as the case may be.

         6.       OBLIGATIONS OF THE COMPANY UPON TERMINATION OF
EMPLOYMENT.  (a) Death of Shull.  In the event of the death of Shull  during the
term hereof,  the Company shall pay to Shull's  spouse,  commencing on the first
day of the month  following his death and continuing for a period of twelve (12)
months  thereafter,  benefits equal to the monthly  installments of Salary which
was then being paid to Shull pursuant to Section 4 herein. Immediately following
such one-year period, the Company shall commence the payment of monthly benefits
to  Shull's  spouse  equal  in  amount  to  one-fourth   (1/4)  of  the  monthly
installments of Salary which was being paid to Shull at


<PAGE>



the time of his death under Section 4 herein,  which monthly  benefits  shall be
paid for a period of twenty  (20)  years or until the death of  Shull's  spouse,
whichever occurs first. In addition,  the Company shall continue at all times to
offer and provide health  insurance  coverage to Shull's  spouse,  in accordance
with the plans,  programs,  practices and policies provided by the Company under
the terms of this  Agreement  at the time of Shull's  death,  until the death of
Shull's  spouse,  except to the extent  such  coverage is or  otherwise  becomes
available to Shull's spouse under the Medicare program of benefits.

         (b) Cause;  Other than for Good Reason. If Shull's  employment shall be
terminated for Cause,  Shull's  employment  under this Agreement shall terminate
without further  obligations to Shull (other than the obligation to pay to Shull
his Salary through the Date of Termination  plus the amount of any  compensation
previously deferred by Shull,  together with accrued interest thereon). If Shull
terminates employment other than for Good Reason, this Agreement shall terminate
without further  obligations to Shull,  other than those obligations  accrued or
earned and vested (if  applicable)  by Shull  through  the Date of  Termination,
including  for  this  purpose,  all  Accrued   Obligations.   All  such  Accrued
Obligations shall be paid to Shull in a lump sum in cash within thirty (30) days
of the Date of Termination.

         (c) Good  Reason;  Other than for Cause or  Disability.  If the Company
shall terminate Shull's employment other than for Cause, Disability, or death or
if Shull shall  terminate his  employment for Good Reason at any time during the
Employment  Period,  except during a three-year  period  following any Change of
Control (in which case the provisions of Section 6(d) shall apply), then in such
event:

                  (i) the  Company  shall  pay to  Shull  in a lump  sum in cash
within  thirty  (30) days after the Date of  Termination  the  aggregate  of the
following amounts:

              A.       to the extent not theretofore paid, Shull's Salary 
through the Date of Termination; and

              B.       the product of (x) the highest Annual Bonus paid to Shull
during the three (3) fiscal years preceding the fiscal year in which the Date of
Termination  occurs (the "Recent  Bonus") and (y) a fraction,  the  numerator of
which is the  number of days in the  current  fiscal  year  through  the date of
Termination and the denominator of which is 365; and

              C.       the product of (x) two (2.0) and (y) the sum of (i) the 
Salary and (ii) the Recent Bonus; and

              D.       in the case of compensation previously deferred by Shull,
all amounts previously deferred (together with any accrued interest thereon) and
not yet paid


<PAGE>



by the Company, and any accrued vacation pay not yet paid by the Company; and

                  (ii) for a two-year period  following the Date of Termination,
the Company  shall  continue  benefits to Shull and/or  Shull's  family at least
equal to those which would have been  provided  to them in  accordance  with the
plans, programs, practices and policies provided under this Agreement if Shull's
employment  had  not  been  terminated,  including  health  insurance  and  life
insurance, in accordance with the most favorable plans,  practices,  programs or
policies  provided by the Company and its subsidiaries  during the 90-day period
immediately preceding the Date of Termination or, if more favorable to Shull, as
in effect at any time  thereafter  with respect to other key employees and their
families.  Notwithstanding the foregoing, however, the Company shall continue at
all times to offer and provide the above-described health insurance coverages to
Shull and his spouse until their respective dates of death, except to the extent
such  coverage is or otherwise  becomes  available to Shull and his spouse under
the Medicare program of benefits.

         (d) Good Reason; Other than for Cause or Disability, following a Change
of Control.  If, during a three year period following any Change of Control, the
Company shall terminate Shull's employment other than for Cause, Disability,  or
death or if Shull shall terminate his employment for Good Reason:

                  (i) the  Company  shall  pay to Shull in a lump sum in cash on
the thirtieth  (30th) day following the Date of Termination the aggregate of the
following amounts:

        A.       to the extent not theretofore paid, Shull's Salary through the
Date of Termination; and

        B. the product of (x) the Recent Bonus and (y) a fraction, the numerator
of which is the  number of days in the  current  fiscal  year  through  the date
of Termination and the denominator of which is 365; and

        C.       the product of (x) three (3.0) and (y) the sum of (i) the 
Salary and (ii) the Recent Bonus; and

        D.       in the case of compensation previously deferred by Shull, all
amounts previously deferred (together with any accrued interest thereon) and not
yet  paid by the  Company,  and any  accrued  vacation  pay not yet  paid by the
Company; and

                  (ii)  for  a   three-year   period   following   the  Date  of
Termination,  the Company shall continue benefits to Shull and/or Shull's family
at least  equal to those which  would have been  provided to them in  accordance
with the plans,  programs,  practices and policies provided under this Agreement
if Shull's employment had not been


<PAGE>



terminated,  including health  insurance and life insurance,  in accordance with
the most  favorable  plans,  practices,  programs  or  policies  provided by the
Company and its subsidiaries during the 90-day period immediately  preceding the
Date of  Termination  or, if more  favorable to Shull,  as in effect at any time
thereafter   with   respect  to  other  key   employees   and  their   families.
Notwithstanding the foregoing,  however, the Company shall continue at all times
to offer and provide the above-described health insurance coverages to Shull and
his spouse  until  their  respective  dates of death,  except to the extent such
coverage is or  otherwise  becomes  available  to Shull and his spouse under the
Medicare program of benefits.

         (e)  Alternative  Excise Tax Cap.  Notwithstanding  the  provisions  of
Section 6(d) hereof,  if any payments or benefits  received or to be received by
Shull  (whether  pursuant  to the terms of this  Agreement  or any  other  plan,
arrangement or agreement with the Company,  any person whose actions result in a
Change of Control  or any person  affiliated  with the  Company or such  person)
constitute  "parachute payments" within the meaning of Section  280G(b)(2)(A) of
the Code and the value  thereof  exceeds 2.99 times  Shull's  "base  amount," as
defined in Section  280G(b)(3) of the Code,  then, in lieu thereof,  the Company
shall pay to Shull, as soon as practicable following the Date of Termination but
in no event  later than  thirty (30) days  thereafter,  a lump sum cash  payment
equal to 2.99 times his "base  amount" (the  "Alternative  Severance  Payment"),
reduced as provided  below.  The value of the payments to be made under  Section
6(e) and Shull's base amount shall be determined in accordance with temporary or
final regulations,  if any, promulgated under Section 280G of the Code and based
upon the advice of the tax counsel referred to below.

         The Alternative Severance Payment shall be reduced by the amount of any
other payment or the value of any benefit received or to be received by Shull in
connection  with a Change  of  Control  of the  Company  or his  termination  of
employment  unless  (i) Shull  shall  have  effectively  waived  his  receipt or
enjoyment  of such  payment  or  benefit  prior  to the date of  payment  of the
Alternative  Severance  Payment,  (ii) in the opinion of tax counsel selected by
the  Company's  independent  auditors,  such other  payment or benefit  does not
constitute a "parachute payment" within the meaning of Section 280G(b)(2) of the
Code,  or (iii) in the opinion of such tax counsel,  the  Alternative  Severance
Payment  plus  all  other  payments  or  benefits  which  constitute  "parachute
payments"  within the meaning of Section  280G(b)(2) of the Code are  reasonable
compensation  for  services  actually  rendered  within  the  meaning of Section
280G(b)(4)  of the  Code or are  otherwise  not  subject  to  disallowance  as a
deduction  by reason of  Section  280G of the  Code.  The value of any  non-cash
benefit or any deferred  payment or benefit  shall be  determined  in accordance
with the principles of Section 280G(d)(3) and (4) of the Code.

     (f) Section 162(m) Limitation.  In the event that the payments due to Shull
under this Section 6 exceed the "reasonable compensation" limitations of Section
162(m)

<PAGE>



of the Code, that portion thereof that would not be deductible by the Company in
the  taxable  year in which the  payment is due shall be deferred by the Company
and paid to Shull on the date that is sixteen (16) months  following the Date of
Termination,  together  with  interest  thereon at the rate  provided in Section
7872(f)(2) of the Code.

         7.  NON-EXCLUSIVITY OF RIGHTS.  Nothing in this Agreement shall prevent
or limit  Shull's  continuing  or future  participation  in any benefit,  bonus,
incentive  or other  plans,  programs,  policies or  practices,  provided by the
Company  and for which  Shull may  qualify,  including  but not  limited  to the
Non-Qualified Supplemental Executive Retirement Plan of the Company (the "SERP")
(or any successor  plan),  nor shall anything  herein limit or otherwise  affect
such  rights  as Shull  may have  under  the SERP or any  stock  option or other
agreements with the Company. Amounts which are vested benefits or which Shull is
otherwise entitled to receive under any plan, policy, practice or program of the
Company at or subsequent to the Date of  Termination,  including but not limited
to the SERP, shall be payable in accordance with the SERP or such plan,  policy,
practice or program.

         8. FULL  SETTLEMENT.  The  Company's  obligation  to make the  payments
provided  for in  this  Agreement  and  otherwise  to  perform  its  obligations
hereunder  shall  not be  affected  by any  set-off,  counterclaim,  recoupment,
defense or other claim, right or action which the Company may have against Shull
or others. In no event shall Shull be obligated to seek other employment or take
any other action by way of mitigation of the amounts  payable to Shull under any
of the provisions of this  Agreement,  but such payments shall be reduced to the
extent of Shull's other earned  income (if any) during any remaining  portion of
the Employment  Period.  Following any Change of Control,  the Company agrees to
pay, to the full extent  permitted  by law,  all legal fees and  expenses  which
Shull may reasonably incur as a result of any contest (regardless of the outcome
thereof)  by  the  Company  or  others  (including  Shull)  of the  validity  or
enforceability  of, or liability  under,  any provision of this Agreement or any
guarantee of performance  thereof,  plus in each case interest at the applicable
Federal rate provided for in Section 7872(f)(2) of the Code.

         9.  RETIREMENT OF SHULL.  Provided that this  Agreement or an extension
thereof remains in effect,  it is understood that Shull shall retire on the last
day of the calendar year during which he reaches  sixty-five  (65) years of age.
In such event,  the Board of Directors of the Company,  at its sole option,  may
offer to extend Shull's  employment on a  year-to-year  basis after the calendar
year in which Shull reaches age sixty-five  (65). At the conclusion of each year
it will be  presumed  that  Shull  will  retire  unless  the Board of  Directors
determines to offer to extend Shull's employment for an additional year.

         Following the retirement of Shull, the Company shall continue at all 
times to offer


<PAGE>



and provide health  insurance  coverages to Shull and his spouse,  in accordance
with the most favorable plans, programs,  practices and policies provided by the
Company  during the 90-day period  immediately  preceding the effective  date of
Shull's  retirement  or, if more  favorable  to Shull,  as in effect at any time
thereafter  with respect to other key  employees and their  families,  until the
death  of Shull  and his  spouse,  except  to the  extent  such  coverage  is or
otherwise  becomes  available to Shull and his spouse under the Medicare program
of benefits,  and provided  further that Shull and his spouse shall pay the same
contribution as that required by other Company employees receiving such benefits
until they reach sixty-five (65) years of age.

         10.  AVAILABILITY OF SHULL AFTER RETIREMENT.  Following his retirement,
Shull  shall at  reasonable  times and  insofar as his  physical  condition  may
permit, hold himself available at the written request of the Board of Director's
of the Company to consult  with and advise the  officers,  directors,  and other
representatives  of the  Company.  Such  requests  for  Shull's  service  shall,
however, be structured so that reasonable  allowances are made for Shull's needs
for vacation time and for other considerations of his physical  well-being.  All
such  services  shall be  provided  by Shull at his  place of  residence  unless
otherwise  agreed  to by  Shull.  Shull  shall not be  required  to  devote  any
prescribed  hours  to  consulting  with  and  giving  advice  to  the  officers,
directors,  and other  representatives of the Company in order to be eligible to
receive any  benefits  that may be  available to him under the SERP or any other
plan or program of the Company.

         If Shull's  physical  condition  shall prevent him from  consulting and
advising with the officers,  directors or other  representatives of the Company,
the benefits  that may be available to Shull under the SERP or any other plan or
program of the Company shall  nonetheless  be paid as and to the extent  therein
provided.

         Shull shall be  reimbursed by the Company for all  reasonable  expenses
incurred  as  a  consultant   and  advisor,   including   expenses  for  travel,
communication,  entertainment  and similar items,  upon presentation of itemized
accounts of such expenditures.

         11. DISCRETION OF BOARD OF DIRECTORS. Notwithstanding any other term or
provision of this  Agreement to the contrary,  nothing stated herein is intended
to,  nor  shall  it be  construed,  to  abrogate,  limit,  alter or  affect  the
authority,  rights and  privileges  of the Board of  Directors of the Company to
remove Shull as Treasurer of the Company,  without Cause,  or during the term of
this  Agreement  to elect as Treasurer of the Company a person other than Shull,
as provided by the laws of the State of Iowa; provided, however, it is expressly
agreed and  understood  that,  in the event any one or any  combination  of such
events  occurs,  unless Shull is terminated for Cause as defined in Section 5(b)
hereof,  Shull shall be entitled to terminate his employment for Good Reason (as
defined in Section  5(c)  hereof) and receive the  benefits  described in either
Section


<PAGE>



6(c) or Section 6(d) of this Agreement, as applicable, in consideration thereof.

         12.  CONFIDENTIAL  INFORMATION;  RESTRICTIVE  COVENANT.  (a) During the
period of his employment, Shull shall hold in fiduciary capacity for the benefit
of the  Company  all  secret  or  confidential  information,  knowledge  or data
relating  to  the  Company  or any of its  subsidiaries,  and  their  respective
businesses, which shall have been obtained by Shull during Shull's employment by
the Company or any of its  subsidiaries  and which shall not be or become public
knowledge  (other than by acts by Shull or his  representatives  in violation of
this Agreement). During a three (3) year period following termination of Shull's
employment with the Company,  Shull shall not, without the prior written consent
of the Company,  communicate or divulge any such information,  knowledge or data
to anyone other than the Company and those designated by it.

         (b) While this  Agreement  remains in effect and Shull is  entitled  to
compensation  or  benefits  pursuant  to Sections 4 through 6 hereof (or, in the
event of termination  of his  employment for Good Reason,  for a period of three
(3) years  thereafter),  Shull shall not directly or indirectly  associate with,
participate in or render service to, whether as an employee,  officer, director,
consultant,  independent  contractor  or  otherwise,  any  organization  that is
engaged in business in  competition  with the Company,  and he shall not himself
engage in any such business on his own account.

         (c) In the event of a  demonstrated  breach  of this  Section  12,  the
parties agree that the Company shall be entitled to seek  equitable  relief in a
court of competent  jurisdiction to prevent any anticipated continuing breach of
the terms and  conditions  of this  Section  12 and to  secure  the  enforcement
thereof. The foregoing remedy shall be exclusive and in lieu of any other remedy
otherwise available to the Company under law.

     13.  SUCCESSORS.  (a) This  Agreement  is personal to Shull and without the
prior written  consent of the Company shall not be assignable by Shull otherwise
than by will or the laws of descent and distribution. This Agreement shall inure
to the benefit of and be enforceable by Shull's legal representatives.

         (b)      This Agreement shall inure to the benefit of and be binding 
upon the Company and its successors and assigns.

         (c) The Company  agrees and  covenants to require (i) any  successor or
assignee  (whether direct or indirect,  by purchase,  merger,  consolidation  or
otherwise)  to all or  substantially  all of the business  and/or  assets of the
Company  through a Change of  Control or  otherwise,  and any,  (ii)  within its
lawful  power to do so, any party  effecting  or taking  steps to  accomplish  a
Change of Control,  to assume  expressly and agree to perform this  Agreement in
the same manner and to the same extent that the Company would be


<PAGE>



required  to perform  it if no such  succession  or Change of Control  had taken
place.  As  used  in  this  Agreement,  "Company"  shall  mean  the  Company  as
hereinbefore  defined  and  any  successor  to its  business  and/or  assets  as
aforesaid  which  assumes and agrees to perform  this  Agreement by operation of
law, or otherwise.

     14. MISCELLANEOUS. (a) This Agreement shall be governed by and construed in
accordance with the laws of the State of Iowa,  without  reference to principles
of  conflict  of  laws.  The  captions  of this  Agreement  are not  part of the
provisions  hereof and shall have no force or effect.  This Agreement may not be
amended  or  modified  otherwise  than by a written  agreement  executed  by the
parties hereto or their respective successors and legal representatives.

         (b) All notices and other communications  hereunder shall be in writing
and shall be given by hand  delivery  to the  other  party or by  registered  or
certified mail, return receipt requested, postage prepaid, addressed as follows:
If the Company, to Casey's General Stores, Inc., P. O. Box 3001, One Convenience

other  address as either  party shall have  furnished to the other in writing in
accordance herewith.  Notice and communications shall be effective when actually
received by the addressee.

         (c)  The  invalidity  or  unenforceability  of any  provision  of  this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement.

         (d) The  Company  may  withhold  from any  amounts  payable  under this
Agreement such Federal, state or local taxes as shall be required to be withheld
pursuant to any applicable law or regulation.

         (e) The Company's or Shull's  failure to insist upon strict  compliance
with any provision  hereof shall not be deemed to be a waiver of such  provision
or any other provision thereof.

         (f) This Agreement contains the entire understanding of the Company and
Shull with respect to the subject matter hereof.  The Original Agreement between
Shull and the Company,  as defined in the preambles hereof, is hereby terminated
and shall be of no further force or effect.

         (g) No change,  amendment or  modification  of this Agreement  shall be
valid unless the same be in writing and signed by the Company and Shull.

                              AMENDED AND RESTATED
                              EMPLOYMENT AGREEMENT


     THIS AMENDED AND RESTATED  EMPLOYMENT  AGREEMENT (the  "Agreement") is made
and entered  into as of the 24th day of October,  1997,  by and between  Casey's
General Stores,  Inc., an Iowa corporation  (the "Company"),  and John G. Harmon
("Harmon").

         WHEREAS,  the  Board  of  Directors  of  the  Company  (the  "Board  of
Directors")  recognizes that the dedication of Harmon as an officer and director
to the affairs and welfare of the Company has resulted in a long and  successful
association; and

         WHEREAS, the Board of Directors further recognizes that the Company has
grown  and  prospered  as a  result  of its  association  with  Harmon,  and has
determined  that it is in the best interest of the Company and its  shareholders
to preserve this association so as to enable the Company to further benefit from
Harmon's  superior  knowledge  and  expertise  in all of its  present and future
business endeavors; and

         WHEREAS,  the Company and Harmon are parties to an Employment Agreement
dated as of July  19,  1994,  as  amended  by a First  Amendment  to  Employment
Agreement  dated as of January 9, 1997  (together,  the  "Original  Agreement"),
providing for the  employment  of Harmon to serve as the Corporate  Secretary of
the Company under the terms and conditions set forth therein; and

         WHEREAS,  the Board of  Directors  has  further  determined  that it is
appropriate  and in the best  interests of the Company and its  shareholders  to
enter into written contractual  arrangements with respect to Harmon's employment
by the Company,  with the  concurrence  of Harmon,  and to amend and restate the
Original Agreement to reflect the same; and

         WHEREAS,  the Board of Directors has further  determined  that it is in
the best interest of the Company and its shareholders to assure that the Company
will have the continued  dedication of Harmon,  notwithstanding the possibility,
threat or occurrence  of a Change of Control (as defined  below) of the Company,
and to further  encourage  Harmon's full attention and dedication to the Company
currently and in the event of any threatened or pending  Change of Control,  and
to provide Harmon with compensation  arrangements upon a Change of Control which
provide him with  compensation  for expected  losses that he would suffer in the
event of a Change  of  Control  and which are  competitive  with  those of other
corporations, and, in order to accomplish these objectives,


<PAGE>



has determined to cause the Company to enter into this Agreement.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
set forth in this Agreement, the parties hereto agree as follows:

     1. CERTAIN DEFINITIONS.  For purposes of this Agreement, and in addition to
the other  definitions  set forth  herein,  the  following  terms shall have the
following meanings:

         a)       "Change of Control" shall mean:

                  (i) the  acquisition  (other  than  from the  Company)  by any
Person (as hereinafter defined), entity or "group" within the meaning of Section
13(d)(3) or  14(d)(2)  of the  Securities  Exchange  Act of 1934 (the  "Exchange
Act"),  (excluding for this purpose, the Company or any employee benefit plan of
the Company,  which acquires  beneficial  ownership of voting  securities of the
Company) of beneficial  ownership  (within the meaning of Rule 13d-3 promulgated
under the  Exchange  Act) of  twenty  percent  (20%) or more of either  the then
outstanding shares of Common Stock, no par value, of the Company or the combined
voting power of the Company's then  outstanding  voting  securities  entitled to
vote  generally  in the election of  directors  (hereinafter  referred to as the
"Common Stock"), unless such beneficial ownership was acquired as a result of an
acquisition  of shares of Common  Stock by the Company  which,  by reducing  the
number of  shares  outstanding,  increases  the  proportionate  number of shares
beneficially owned by such Person,  entity or "group" to twenty percent (20%) or
more of the Common Stock of the Company  then  outstanding;  provided,  however,
that if a Person,  entity or "group" shall become the beneficial owner of twenty
percent  (20%) or more of the Common  Stock of the Company then  outstanding  by
reason of share  purchases by the Company and shall,  after such share purchases
by the Company,  become the beneficial owner of any additional  shares of Common
Stock of the  Company,  then such Person,  entity or "group"  shall be deemed to
have met the conditions hereof; or

                  (ii)  individuals  who, as of the date hereof,  constitute the
Board of Directors (as of the date hereof,  the "Incumbent Board") cease for any
reason to  constitute  at least a majority of the Board of  Directors,  provided
that  any  person  becoming  a  director  subsequent  to the date  hereof  whose
election, or nomination for election by the Company's shareholders, was approved
by a vote of at least a majority of the directors then  comprising the Incumbent
Board  (other than an election or  nomination  of an  individual  whose  initial
assumption  of office is in  connection  with an actual or  threatened  election
contest relating to the election of the directors of the Company,  as such terms
are used in Rule 14a-11 of Regulation  14A  promulgated  under the Exchange Act)
shall be, for purposes of this Agreement considered as though such person were a
member of the Incumbent Board; or


<PAGE>



                  (iii)  approval  by  the  shareholders  of  the  Company  of a
reorganization,  merger,  consolidation  (in each  case,  with  respect to which
persons  who were the  shareholders  of the  Company  immediately  prior to such
reorganization, merger or consolidation do not, immediately thereafter, own more
than fifty percent (50%) of the combined voting power entitled to vote generally
in  the  election  of  directors  of the  reorganized,  merged  or  consolidated
company's then outstanding voting securities) or a liquidation or dissolution of
the  Company  or of the sale of all or  substantially  all of the  assets of the
Company.

         (b) "Annual Increase" shall take effect on each January 1 for which the
benefit at issue is payable  and shall  mean fifty  percent  (50%) of the annual
increase in the National Consumer Price Index for the City of Des Moines,  Iowa,
as published by the United States Bureau of Labor Statistics.

         (c) "Annual  Bonus" shall mean any bonus  payable at the  discretion of
the Board of Directors  of the Company,  on such terms and in such amounts as it
shall determine.

         (d)  "Employment  Period"  shall mean the term of  Harmon's  employment
under this Agreement, as set forth in Section 2 hereof.

         (e)      "Code" shall mean the Internal Revenue Code of 1986, as 
amended.

         (f) "Accrued  Obligations"  shall mean (i) Harmon's  Salary through the
Date of Termination at the rate in effect on the Date of  Termination,  (ii) the
product of the Annual  Bonus paid to Harmon for the last full  fiscal year and a
fraction,  the  numerator  of which is the number of days in the current  fiscal
year through the Date of  Termination,  and the  denominator of which is 365 and
(iii) any compensation  previously  deferred (together with any accrued interest
thereon)  and not yet paid by the Company and any accrued  vacation  pay not yet
paid by the Company.

         (g) "Person"  shall mean any  individual,  firm,  corporation  or other
entity,  and shall  include  any  successor  (by  merger or  otherwise)  and all
"affiliates" and "associates" of such entity (as those terms are defined in Rule
12b-2 of the General Rules and Regulations under the Exchange Act).

         2. EMPLOYMENT AND TERM. The Company agrees to employ Harmon, and Harmon
agrees to serve the Company,  as Corporate Secretary of the Company until August
1, 2001,  unless his  employment  is otherwise  terminated  as provided  herein;
provided, however, that in the event of a Change of Control during the foregoing
Employment Period, this Agreement shall continue in full force and effect for an
additional  period of three (3) years following the expiration of the Employment
Period


<PAGE>



(until August 1, 2004).

         3.  DUTIES  OF  HARMON.  During  the  period of his  employment  in the
capacity of Secretary, Harmon agrees to devote his professional skill and energy
to the faithful and full satisfaction of his duties as Corporate  Secretary.  It
is agreed and  understood  that Harmon will perform all duties  assigned to him,
which shall be substantially  the same as those performed by Harmon as Secretary
of the Company prior to the date of this Agreement  (including status,  offices,
titles and reporting  requirements),  to the full  satisfaction  of the Board of
Directors.  The  Company  agrees  that  Harmon  shall  have such  authority  and
discretion  as is  necessary  to fully and  faithfully  perform  his duties in a
proper and efficient manner, subject to review by the Board of Directors.

         During the period of his  employment,  it shall not be a  violation  of
this Agreement for Harmon to (i) serve on corporate,  civil or charitable boards
or committees,  (ii) deliver lectures or fulfill speaking  engagements and (iii)
manage personal  investments,  so long as such  activities do not  significantly
interfere with the  performance of Harmon's  responsibilities  as an employee of
the Company in accordance  with this Agreement.  It is expressly  understood and
agreed that to the extent that any such activities have been conducted by Harmon
prior to the date  hereof,  the  continued  conduct of such  activities  (or the
conduct of  activities  similar in nature and scope  thereto)  subsequent to the
date hereof shall not thereafter be deemed to interfere with the  performance of
Harmon's responsibilities to the Company.

         4.  COMPENSATION.  The Company  shall pay to Harmon an annual salary of
One Hundred Thirty-Five  Thousand Dollars  ($135,000),  payable in equal monthly
installments,  or such  other  amount as shall be  mutually  agreed  upon by the
Company and Harmon (the  "Salary").  In addition,  Harmon and/or Harmon's family
shall be entitled to receive all benefits  presently provided or those which may
hereafter  be provided  generally by the Company to its  employees,  officers or
directors,  including health insurance and life insurance.  With respect to such
health  insurance  benefits,  the  Company  agrees  that at all times the health
insurance  coverages  available  to Harmon and his spouse under such plans shall
include  provisions  providing for lifetime benefits payable on behalf of Harmon
and his spouse of not less than One Million Dollars  ($1,000,000)  each, or such
other amount as the Company and Harmon may  specifically  agree upon in writing,
subject, however, to any limitations, restrictions or conditions that shall from
time to time be necessary to satisfy the  requirements of applicable  federal or
state laws and regulations.

     5. TERMINATION OF EMPLOYMENT. (a) Death or Disability.  Harmon's employment
under this Agreement shall terminate  automatically  upon Harmon's death. If the
Company  determines  in good faith that the  Disability  of Harmon has  occurred
(pursuant to the  definition of  "Disability"  set forth below),  it may give to
Harmon written

<PAGE>



notice of its  intention to terminate  Harmon's  employment  as Secretary of the
Company.  In such event,  Harmon's  employment  with the Company shall terminate
effective  on the  thirtieth  (30th) day after  receipt of such notice by Harmon
(the "Disability  Effective  Date"),  provided that, within the thirty (30) days
after such receipt,  Harmon shall not have returned to full-time  performance of
his duties.  For purposes of this  Agreement,  "Disability  means  disability or
incapacity  of  Harmon  which,   at  least   twenty-six  (26)  weeks  after  its
commencement,  is determined by the Board of Directors  upon  competent  medical
advice to be such as to prevent Harmon from performing  substantially all of the
duties as Secretary of the Company.

         Notwithstanding any Disability on the part of Harmon, the Company shall
continue at all times to offer and provide health insurance  coverages to Harmon
and his spouse, in accordance with the plans,  programs,  practices and policies
provided by the  Company  during the 90-day  period  immediately  preceding  the
Disability  Effective Date or, if more favorable to Harmon,  as in effect at any
time thereafter  with respect to other key employees and their  families,  until
the death of Harmon and his  spouse,  except to the extent  such  coverage is or
otherwise  becomes available to Harmon and his spouse under the Medicare program
of benefits.

         (b) Cause. The Company may terminate  Harmon's  employment for "Cause."
For  purposes of this  Agreement,  "Cause"  means (i) an act or acts of personal
dishonesty  taken by Harmon  and  intended  to result  in  substantial  personal
enrichment of Harmon at the expense of the Company,  (ii) repeated violations by
Harmon of  Harmon's  obligations  under  Section 3 of this  Agreement  which are
demonstratively  willful  and  deliberate  on  Harmon's  part and  which are not
remedied in a reasonable period of time after receipt of written notice from the
Company or (iii) the conviction of Harmon of a felony when such conviction is no
longer subject to direct appeal.

     (c) Good Reason.  Harmon's  employment may be terminated by Harmon for Good
Reason. For purposes of this Agreement, "Good Reason" means:

                  (i) the assignment to Harmon of any duties inconsistent in any
respect with Harmon's position (including status,  office,  titles and reporting
requirements),  authority, duties or responsibilities as contemplated by Section
3 of this  Agreement,  or any other  action by the  Company  which  results in a
diminution in such position,  authority,  duties or responsibilities,  excluding
for this purpose an isolated,  insubstantial and inadvertent action not taken in
bad faith and which is remedied by the Company  promptly after receipt of notice
thereof given by Harmon;

                  (ii) Any failure by the Company to comply with the  provisions
of  Section 4 of this  Agreement,  other  than an  isolated,  insubstantial  and
inadvertent  failure  not  occurring  in bad faith and which is  remedied by the
Company promptly after receipt


<PAGE>



of notice thereof given by Harmon;

                  (iii) the Company's requiring Harmon to be based at any office
or location other than the Company's Corporate  Headquarters facility in Ankeny,
Iowa,  except for travel  reasonably  required  in the  performance  of Harmon's
responsibilities;

                 (iv) any  purported  termination  by the  Company  of  Harmon's
employment otherwise  than for death,  Disability  or Cause as expressly  
permitted by this Agreement; or

                  (v)      any failure by the Company to comply with and satisfy
Section 13(c) of this Agreement.

         For  purposes of this Section  5(c),  any good faith  determination  of
"Good Reason" made by Harmon shall be conclusive.

         (d) Notice of Termination.  Any termination by the Company for Cause or
by Harmon for Good Reason shall be  communicated by Notice of Termination to the
other party hereto given in accordance with Section 14(b) of this Agreement. For
purposes of this  Agreement,  a "Notice of  Termination"  means a written notice
which (i) indicates the specific termination  provision in this Agreement relied
upon, (ii) sets forth in reasonable detail the facts and  circumstances  claimed
to provide a basis for termination of Harmon's employment under the provision so
indicated and (iii) if the Date of Termination  (as defined below) is other than
the date of receipt of such notice,  specifies the termination  date (which date
shall be not more than fifteen (15) days after the giving of such  notice).  The
failure  by  Harmon  to set  forth  in the  Notice  of  Termination  any fact or
circumstance  which  contributes to a showing of Good Reason shall not waive any
right of  Harmon  hereunder  or  preclude  Harmon  from  asserting  such fact or
circumstance in enforcing his rights hereunder.

         (e)  Date of  Termination.  "Date  of  Termination"  means  the date of
receipt of the Notice of Termination or any later date specified therein, as the
case may be; provided, however, that (i) if Harmon's employment is terminated by
the Company other than for Cause or Disability, the Date of Termination shall be
the date on which the Company  notifies  Harmon of such  termination and (ii) if
Harmon's employment is terminated by reason of death or Disability,  the Date of
Termination  shall be the date of death of  Harmon or the  Disability  Effective
Date, as the case may be.

     6. OBLIGATIONS OF THE COMPANY UPON TERMINATION OF EMPLOYMENT.  (a) Death of
Harmon. In the event of the death of Harmon during the term hereof,  the Company
shall pay to Harmon's spouse, commencing on the first day of the month following
his death and continuing for a period of twelve (12) months thereafter, benefits
equal to the monthly installments of Salary which was then being paid

<PAGE>



to Harmon  pursuant to Section 4 herein.  Immediately  following  such  one-year
period,  the Company shall commence the payment of monthly  benefits to Harmon's
spouse equal in amount to one-fourth (1/4) of the monthly installments of Salary
which was being paid to Harmon at the time of his death under  Section 4 herein,
which monthly  benefits shall be paid for a period of twenty (20) years or until
the death of Harmon's spouse,  whichever occurs first. In addition,  the Company
shall  continue at all times to offer and provide health  insurance  coverage to
Harmon's spouse, in accordance with the plans, programs,  practices and policies
provided  by the  Company  under  the  terms  of this  Agreement  at the time of
Harmon's death,  until the death of Harmon's  spouse,  except to the extent such
coverage is or otherwise becomes available to Harmon's spouse under the Medicare
program of benefits.

         (b) Cause; Other than for Good Reason. If Harmon's  employment shall be
terminated for Cause,  Harmon's  employment under this Agreement shall terminate
without  further  obligations  to Harmon  (other than the  obligation  to pay to
Harmon  his  Salary  through  the Date of  Termination  plus the  amount  of any
compensation  previously  deferred by Harmon,  together  with  accrued  interest
thereon).  If Harmon  terminates  employment  other than for Good  Reason,  this
Agreement shall  terminate  without  further  obligations to Harmon,  other than
those obligations accrued or earned and vested (if applicable) by Harmon through
the Date of Termination,  including for this purpose,  all Accrued  Obligations.
All  such  Accrued  Obligations  shall be paid to  Harmon  in a lump sum in cash
within thirty (30) days of the Date of Termination.

         (c) Good  Reason;  Other than for Cause or  Disability.  If the Company
shall terminate Harmon's employment other than for Cause,  Disability,  or death
or if Harmon shall  terminate his  employment for Good Reason at any time during
the Employment Period, except during a three-year period following any Change of
Control (in which case the provisions of Section 6(d) shall apply), then in such
event:

                  (i) the  Company  shall  pay to  Harmon  in a lump sum in cash
within  thirty  (30) days after the Date of  Termination  the  aggregate  of the
following amounts:

                           A.       to the extent not theretofore paid, Harmon's
Salary through the Date of Termination; and

                           B.       the product of (x) the highest Annual Bonus
paid to Harmon during the three (3) fiscal years preceding the fiscal year in
which the Date of Termination  occurs (the "Recent  Bonus") and (y) a fraction,
the  numerator of which is the  number of days in the  current  fiscal  year
through  the date of Termination and the denominator of which is 365; and

                           C.       the product of (x) two (2.0) and (y) the 
sum of (i) the Salary


<PAGE>



                  and (ii) the Recent Bonus; and

                           D.       in the case of compensation previously 
deferred by Harmon, all amounts previously deferred (together with any accrued 
interest thereon) and not yet paid by the  Company,  and any accrued  vacation 
pay not yet paid by the Company; and

                  (ii) for a two-year period  following the Date of Termination,
the Company shall continue  benefits to Harmon and/or  Harmon's  family at least
equal to those which would have been  provided  to them in  accordance  with the
plans,  programs,  practices  and  policies  provided  under this  Agreement  if
Harmon's employment had not been terminated, including health insurance and life
insurance, in accordance with the most favorable plans,  practices,  programs or
policies  provided by the Company and its subsidiaries  during the 90-day period
immediately  preceding the Date of Termination  or, if more favorable to Harmon,
as in effect at any time  thereafter  with  respect to other key  employees  and
their  families.  Notwithstanding  the  foregoing,  however,  the Company  shall
continue at all times to offer and provide the above-described  health insurance
coverages to Harmon and his spouse until their respective dates of death, except
to the extent such coverage is or otherwise  becomes available to Harmon and his
spouse under the Medicare program of benefits.

         (d) Good Reason; Other than for Cause or Disability, following a Change
of Control.  If, during a three year period following any Change of Control, the
Company shall terminate Harmon's employment other than for Cause, Disability, or
death or if Harmon shall terminate his employment for Good Reason:

                  (i) the  Company  shall pay to Harmon in a lump sum in cash on
the thirtieth  (30th) day following  after the Date of Termination the aggregate
of the following amounts:

                           A.       to the extent not theretofore paid, Harmon's
Salary through the Date of Termination; and

                           B.       the product of (x) the Recent Bonus and (y)
a fraction, the numerator of which is the number of days in the current fiscal 
year through the date of Termination and the denominator of which is 365; and

                           C.       the product of (x) three (3.0) and (y) the 
sum of (i) the Salary and (ii) the Recent Bonus; and

                           D.       in the case of compensation previously 
deferred by Harmon, all amounts previously deferred (together with any accrued 
interest thereon) and not yet paid by the  Company,  and any accrued  vacation 
pay not yet paid by the Company; and


<PAGE>



                  (ii)  for  a   three-year   period   following   the  Date  of
Termination,  the Company  shall  continue  benefits to Harmon  and/or  Harmon's
family  at least  equal to those  which  would  have  been  provided  to them in
accordance with the plans, programs,  practices and policies provided under this
Agreement  if Harmon's  employment  had not been  terminated,  including  health
insurance and life  insurance,  in  accordance  with the most  favorable  plans,
practices,  programs  or policies  provided by the Company and its  subsidiaries
during the 90-day period  immediately  preceding the Date of Termination  or, if
more favorable to Harmon,  as in effect at any time  thereafter  with respect to
other key employees and their families.  Notwithstanding the foregoing, however,
the Company shall continue at all times to offer and provide the above-described
health insurance coverages to Harmon and his spouse until their respective dates
of death,  except to the extent such coverage is or otherwise  becomes available
to Harmon and his spouse under the Medicare program of benefits.

         (e)  Alternative  Excise Tax Cap.  Notwithstanding  the  provisions  of
Section 6(d) hereof,  if any payments or benefits  received or to be received by
Harmon  (whether  pursuant  to the terms of this  Agreement  or any other  plan,
arrangement or agreement with the Company,  any person whose actions result in a
Change of Control  or any person  affiliated  with the  Company or such  person)
constitute  "parachute payments" within the meaning of Section  280G(b)(2)(A) of
the Code and the value thereof  exceeds 2.99 times  Harmon's  "base  amount," as
defined in Section  280G(b)(3) of the Code,  then, in lieu thereof,  the Company
shall pay to Harmon,  as soon as  practicable  following the Date of Termination
but in no event later than thirty (30) days thereafter,  a lump sum cash payment
equal to 2.99 times his "base  amount" (the  "Alternative  Severance  Payment"),
reduced as provided  below.  The value of the payments to be made under  Section
6(e) and Harmon's base amount shall be determined in accordance  with  temporary
or final  regulations,  if any,  promulgated  under Section 280G of the Code and
based upon the advice of the tax counsel referred to below.

         The Alternative Severance Payment shall be reduced by the amount of any
other  payment or the value of any benefit  received or to be received by Harmon
in  connection  with a Change of Control of the  Company or his  termination  of
employment  unless  (i)  Harmon  shall have  effectively  waived his  receipt or
enjoyment  of such  payment  or  benefit  prior  to the date of  payment  of the
Alternative  Severance  Payment,  (ii) in the opinion of tax counsel selected by
the  Company's  independent  auditors,  such other  payment or benefit  does not
constitute a "parachute payment" within the meaning of Section 280G(b)(2) of the
Code,  or (iii) in the opinion of such tax counsel,  the  Alternative  Severance
Payment  plus  all  other  payments  or  benefits  which  constitute  "parachute
payments"  within the meaning of Section  280G(b)(2) of the Code are  reasonable
compensation  for  services  actually  rendered  within  the  meaning of Section
280G(b)(4)  of the  Code or are  otherwise  not  subject  to  disallowance  as a
deduction  by reason of  Section  280G of the  Code.  The value of any  non-cash
benefit or any deferred payment or benefit


<PAGE>



shall be determined in accordance with the principles of Section 280G(d)(3) and 
(4) of the Code.

         (f) Section  162(m)  Limitation.  In the event that the payments due to
Harmon under this Section 6 exceed the "reasonable  compensation" limitations of
Section 162(m) of the Code, that portion thereof that would not be deductible by
the Company in the taxable year in which the payment is due shall be deferred by
the Company and paid to Harmon on the date that is sixteen (16) months following
the Date of Termination,  together with interest thereon at the rate provided in
Section 7872(f)(2) of the Code.

         7.  NON-EXCLUSIVITY OF RIGHTS.  Nothing in this Agreement shall prevent
or limit  Harmon's  continuing or future  participation  in any benefit,  bonus,
incentive  or other  plans,  programs,  policies or  practices,  provided by the
Company  and for which  Harmon may  qualify,  including  but not  limited to the
Non-Qualified Supplemental Executive Retirement Plan of the Company (the "SERP")
(or any successor  plan),  nor shall anything  herein limit or otherwise  affect
such  rights as  Harmon  may have  under  the SERP or any stock  option or other
agreements  with the Company.  Amounts which are vested benefits or which Harmon
is otherwise entitled to receive under any plan, policy,  practice or program of
the  Company at or  subsequent  to the Date of  Termination,  including  but not
limited to the SERP,  shall be payable in accordance with the SERP or such plan,
policy, practice or program.

         8. FULL  SETTLEMENT.  The  Company's  obligation  to make the  payments
provided  for in  this  Agreement  and  otherwise  to  perform  its  obligations
hereunder  shall  not be  affected  by any  set-off,  counterclaim,  recoupment,
defense or other  claim,  right or action  which the  Company  may have  against
Harmon or others. In no event shall Harmon be obligated to seek other employment
or take any other action by way of mitigation  of the amounts  payable to Harmon
under  any of the  provisions  of this  Agreement,  but such  payments  shall be
reduced to the  extent of  Harmon's  other  earned  income  (if any)  during any
remaining portion of the Employment Period. Following any Change of Control, the
Company  agrees to pay, to the full extent  permitted by law, all legal fees and
expenses  which  Harmon  may  reasonably  incur  as  a  result  of  any  contest
(regardless of the outcome thereof) by the Company or others (including  Harmon)
of the validity or enforceability  of, or liability under, any provision of this
Agreement or any guarantee of performance thereof, plus in each case interest at
the applicable Federal rate provided for in Section 7872(f)(2) of the Code.

         9.  RETIREMENT OF HARMON.  Provided that this Agreement or an extension
thereof remains in effect, it is understood that Harmon shall retire on the last
day of the calendar year during which he reaches  sixty-five  (65) years of age.
In such event,  the Board of Directors of the Company,  at its sole option,  may
offer to extend Harmon's  employment on a year-to-year  basis after the calendar
year in which Harmon


<PAGE>



reaches age sixty-five  (65). At the conclusion of each year it will be presumed
that Harmon will retire  unless the Board of  Directors  determines  to offer to
extend Harmon's employment for an additional year.

         Following the  retirement of Harmon,  the Company shall continue at all
times to offer and provide health insurance  coverages to Harmon and his spouse,
in accordance with the most favorable  plans,  programs,  practices and policies
provided by the  Company  during the 90-day  period  immediately  preceding  the
effective date of Harmon's  retirement  or, if more  favorable to Harmon,  as in
effect and any time  thereafter  with respect to other key  employees  and their
families,  until the death of Harmon and his  spouse,  except to the extent such
coverage is or  otherwise  becomes  available to Harmon and his spouse under the
Medicare  program of benefits,  and provided  further that Harmon and his spouse
shall pay the same  contribution  as that  required of other  Company  employees
receiving such benefits until they reach sixty-five (65) years of age.

         10. AVAILABILITY OF HARMON AFTER RETIREMENT.  Following his retirement,
Harmon  shall at  reasonable  times and insofar as his  physical  condition  may
permit, hold himself available at the written request of the Board of Director's
of the Company to consult  with and advise the  officers,  directors,  and other
representatives  of the  Company.  Such  requests for  Harmon's  service  shall,
however, be structured so that reasonable allowances are made for Harmon's needs
for vacation time and for other considerations of his physical  well-being.  All
such  services  shall be  provided  by Harmon at his place of  residence  unless
otherwise  agreed to by  Harmon.  Harmon  shall not be  required  to devote  any
prescribed  hours  to  consulting  with  and  giving  advice  to  the  officers,
directors,  and other  representatives of the Company in order to be eligible to
receive any  benefits  that may be  available to him under the SERP or any other
plan or program of the Company.

         If Harmon's  physical  condition  shall prevent him from consulting and
advising with the officers,  directors or other  representatives of the Company,
the benefits that may be available to Harmon under the SERP or any other plan or
program of the Company shall  nonetheless  be paid as and to the extent  therein
provided.

         Harmon shall be reimbursed by the Company for all  reasonable  expenses
incurred  as  a  consultant   and  advisor,   including   expenses  for  travel,
communication,  entertainment  and similar items,  upon presentation of itemized
accounts of such expenditures.

         11. DISCRETION OF BOARD OF DIRECTORS. Notwithstanding any other term or
provision of this  Agreement to the contrary,  nothing stated herein is intended
to,  nor  shall  it be  construed,  to  abrogate,  limit,  alter or  affect  the
authority,  rights and  privileges  of the Board of  Directors of the Company to
remove Harmon as Corporate  Secretary of the Company,  without Cause,  or during
the term of this Agreement to elect


<PAGE>



as Corporate Secretary of the Company a person other than Harmon, as provided by
the laws of the State of Iowa;  provided,  however,  it is expressly  agreed and
understood  that, in the event any one or any combination of such events occurs,
unless Harmon is terminated for Cause as defined in Section 5(b) hereof,  Harmon
shall be entitled to  terminate  his  employment  for Good Reason (as defined in
Section 5(c) hereof) and receive the benefits  described in either  Section 6(c)
or Section 6(d) of this Agreement, as applicable, in consideration thereof.

         12.  CONFIDENTIAL  INFORMATION;  RESTRICTIVE  COVENANT.  (a) During the
period of his  employment,  Harmon  shall  hold in  fiduciary  capacity  for the
benefit of the Company all secret or confidential information, knowledge or data
relating  to  the  Company  or any of its  subsidiaries,  and  their  respective
businesses,  which shall have been obtained by Harmon during Harmon's employment
by the  Company  or any of its  subsidiaries  and  which  shall not be or become
public  knowledge  (other  than by  acts by  Harmon  or his  representatives  in
violation  of  this  Agreement).  During  a  three  (3)  year  period  following
termination of Harmon's  employment with the Company,  Harmon shall not, without
the prior  written  consent of the  Company,  communicate  or  divulge  any such
information,  knowledge  or data to  anyone  other  than the  Company  and those
designated by it.

         (b) While this  Agreement  remains in effect and Harmon is  entitled to
compensation  or  benefits  pursuant  to Sections 4 through 6 hereof (or, in the
event of termination  of his  employment for Good Reason,  for a period of three
(3) years thereafter),  Harmon shall not directly or indirectly  associate with,
participate in or render service to, whether as an employee,  officer, director,
consultant,  independent  contractor  or  otherwise,  any  organization  that is
engaged in business in  competition  with the Company,  and he shall not himself
engage in any such business on his own account.

         (c) In the event of a  demonstrated  breach  of this  Section  12,  the
parties agree that the Company shall be entitled to seek  equitable  relief in a
court of competent  jurisdiction to prevent any anticipated continuing breach of
the terms and  conditions  of this  Section  12 and to  secure  the  enforcement
thereof. The foregoing remedy shall be exclusive and in lieu of any other remedy
otherwise available to the Company under law.

     13.  SUCCESSORS.  (a) This  Agreement is personal to Harmon and without the
prior written consent of the Company shall not be assignable by Harmon otherwise
than by will or the laws of descent and distribution. This Agreement shall inure
to the benefit of and be enforceable by Harmon's legal representatives.

         (b)      This Agreement shall inure to the benefit of and be binding 
upon the Company and its successors and assigns.



<PAGE>



         (c) The Company  agrees and  covenants to require (i) any  successor or
assignee  (whether direct or indirect,  by purchase,  merger,  consolidation  or
otherwise)  to all or  substantially  all of the business  and/or  assets of the
Company  through a Change of Control or  otherwise,  and, (ii) within its lawful
power to do so, any party  effecting or taking  steps to  accomplish a Change of
Control,  to assume  expressly  and agree to perform this  Agreement in the same
manner and to the same extent  that the Company  would be required to perform it
if no such  succession  or Change of Control  had taken  place.  As used in this
Agreement,  "Company"  shall mean the  Company as  hereinbefore  defined and any
successor to its business and/or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law, or otherwise.

     14. MISCELLANEOUS. (a) This Agreement shall be governed by and construed in
accordance with the laws of the State of Iowa,  without  reference to principles
of  conflict  of  laws.  The  captions  of this  Agreement  are not  part of the
provisions  hereof and shall have no force or effect.  This Agreement may not be
amended  or  modified  otherwise  than by a written  agreement  executed  by the
parties hereto or their respective successors and legal representatives.

         (b) All notices and other communications  hereunder shall be in writing
and shall be given by hand  delivery  to the  other  party or by  registered  or
certified mail, return receipt requested, postage prepaid, addressed as follows:
If the Company, to Casey's General Stores, Inc., P. O. Box 3001, One Convenience
Blvd.,  Ankeny,  Iowa  50021,  Attention:  President;  and if to Harmon,  to his
address appearing on the books of the Company,  or to his residence,  or to such
other  address as either  party shall have  furnished to the other in writing in
accordance herewith.  Notice and communications shall be effective when actually
received by the addressee.

         (c)  The  invalidity  or  unenforceability  of any  provision  of  this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement.

         (d) The  Company  may  withhold  from any  amounts  payable  under this
Agreement such Federal, state or local taxes as shall be required to be withheld
pursuant to any applicable law or regulation.

         (e) The Company's or Harmon's failure to insist upon strict  compliance
with any provision  hereof shall not be deemed to be a waiver of such  provision
or any other provision thereof.

         (f) This Agreement contains the entire understanding of the Company and
Harmon with respect to the subject matter hereof. The Original Agreement between
the Company and Harmon, as defined in the preambles hereof, is hereby terminated
and shall be of no further force or effect.


<PAGE>


         (g) No change,  amendment or  modification  of this Agreement  shall be
valid unless the same be in writing and signed by the Company and Harmon.

         (h) This Agreement may be executed in any number of counterparts,  each
of which shall be deemed to be an original and all of which taken together shall
constitute one and the same  instrument with the same force and effect as if all
the parties had executed the same document.

         IN WITNESS WHEREOF,  the respective  parties have caused this Agreement
to be executed as of the day and year first above written.
