such termination, is given to the Employee by the Committee and, subsequently, a
majority of the Board finds,  after reasonable notice to the Employee (but in no
event less than  fifteen  (15) days' prior  notice) and an  opportunity  for the

the Employee to constitute Good Reason. Termination of the Employee's employment
by the Employee  pursuant to this Section 4 shall be effective five (5) business
days after the Employee  gives notice  thereof to the  Company.  This  Agreement

         full base salary earned by the Employee  through the  Termination  Date
         and unpaid at the Termination  Date,  calculated at the highest rate of
         base salary in effect at any time during the twelve months  immediately
         preceding  the  Termination  Date,  (II) the amount of any base  salary
         attributable  to vacation  earned by the  Employee but not taken before
         the  Termination  Date,  (III)  any  annualized  bonus  accrued  to the

         Date,  plus (IV) all other amounts earned by the Employee and unpaid at
         the Termination Date.

Section 4 hereof,  the  employee  shall be  entitled  to receive  the  following

         prescription drug and long- and short-term  disability plans,  programs
         or arrangements, whether group or individual, in which the Employee was
         entitled  to  participate  at any time  during the twelve  month-period
         prior to the Termination Date, until the earliest to occur of (I) three
         years after the Termination  Date; (II) the Employee's  death (provided

         death);  or (III)  with  respect  to any  particular  plan,  program or
         arrangement,  the  date  he  is  afforded  a  comparable  benefit  at a
         comparable cost to the Employee by a subsequent employer.  In the event
         that  the  Employee's  participation  in  any  such  plan,  program  or
         arrangement of the Company is prohibited,  the Company shall

                                       14

         those which the  Employee  is  entitled  to receive  under  such  plan,
         program or arrangement for such period.                                
                  (b) The Company  shall pay to the  Employee all legal fees and
         expenses (including legal fees and expenses incurred in connection with
         an  arbitration  proceeding  engaged in  pursuant to Section 10 hereof)

         (including all such fees and expenses,  if any,  incurred in contesting
         or disputing  any such  termination  or in seeking to obtain or enforce
         any right or benefit  provided  to the  Employee by this  Agreement  or
         under  any  other  plan,  program  or  arrangement  of the  Company  or
         agreement with the Company),  as and when such fees and expenses become
         due.
                  (iii) The  Employee  shall not be  required  to  mitigate  the
amount of any payment or benefit provided for in this Section 5 by seeking other
employment or otherwise.
                  (iv) The amount of any payment or benefit provided for in this
Section 5 shall not be reduced by any  compensation,  benefits or other  amounts
paid to or earned by the  Employee  as the  result of  employment  with  another
employer after the Termination Date or otherwise.

                  (v) In the event that any payment hereunder, together with any
other payment or the value of any benefit  received in connection  with a Change
in Control or the  termination  or the  Employee's  employment  pursuant to this
Agreement or any plan,  agreement or other  arrangement  between the Company and
the  Employee  (or any  member  of  Company's  affiliated  group as such term is
defined in Section 1504 of the Code,  without regard to Section 1504(b) thereof)
would result in the  imposition of an excise tax under Section 4999 of the Code,
the payment  hereunder  may, at the election of the Employee,  be reduced by the
amount necessary to prevent the imposition of such excise tax. The Company shall
engage tax counsel  selected by the Employee and  reasonably  acceptable  to the
Company to advise the Employee  regarding  any  potential  excise tax  liability
under  Section  4999 of the  Code  and as to any  benefit  or  detriment  to the
Employee of making the reduction election provided for hereunder.  In making the
determinations  required  in  order  to give  the  advice  contemplated  by this
Paragraph  (v),  tax counsel may rely on benefit  consultants,  accountants  and
other  experts.  The  Company  agrees to pay all fees and  expenses  of such tax
counsel and other experts.

                  6. Payment Obligations  Absolute.  The Company's obligation to
pay the  Employee  the amounts  provided  for  hereunder  shall be absolute  and
unconditional and shall not be affected by any circumstances, including, without
limitation, any set-off, counterclaim,  recoupment, defense or other right which
the  Company  may  have  against  him or  anyone  else  and,  including  without
limitation,  any  defense  or claim  based on a breach  by the  Employee  of the
covenants  contained herein.  All amounts payable by the Company hereunder shall
be paid without  notice or demand.  Except as  expressly  provided  herein,  the
Company  waives all rights which it may now have or may hereafter have conferred
upon it, by statute or otherwise,  to amend,  terminate,  cancel or rescind this
Agreement  in whole or in part.  Subject  to the  right of the  Company  to seek
arbitration under Section 10 hereof and recover any payment made hereunder, each
and every payment made hereunder by the Company shall be final,  and the Company
shall not seek to recover all or any part of such  payment  from the Employee or
from whomsoever may be entitled thereto, for any reason whatsoever.

the Company pursuant to Section 3(iv) hereof or by

         his  or  her  relationship  with  the  Company  or  any  subsidiary  or
         affiliated company of the Company.
                  (ii) In the event of any breach of the foregoing covenant, the
Employee  acknowledges  that the Company's  remedy at law is inadequate and that
the Company shall be entitled to seek injunctive relief.
                  8.  Successors; Binding Agreement.
                  (i)  This  Agreement  shall  be  binding  upon  any  successor
(whether direct or indirect, by purchase, merger, consolidation,  liquidation or
otherwise)  to all or  substantially  all of the 

                                       18



business and/or assets of the Company.  Additionally,  the Company shall require
any such  successor  expressly  to  agree to  assume  and to  assume  all of the
obligations of the Company under this Agreement upon or prior to such succession
taking place. A copy of such  assumption and agreement shall be delivered to the
Employee  promptly after its execution by the successor.  Failure of the Company
to obtain such agreement prior to the effectiveness of any such succession shall
be a breach of this Agreement and, as a result of such breach, the Company shall
pay to the  Employee  the  benefits  as  provided  in Section 5 hereof as if the
Company  had  terminated  the  Employee's  employment  on the date on which such
succession becomes effective,  without Cause, upon a Change in Control.  As used
in this Agreement,  "Company" shall mean the Company as hereinbefore defined and
any  successor to its business and or assets as  aforesaid,  whether or not such
successor executes and delivers the agreement provided for in this Section 8(i).
                  (ii)  This  Agreement  is  personal  to the  Employee  and the
Employee may not assign or transfer any part of his rights or duties  hereunder,
or any compensation due to him hereunder,  to any other person, except that this
Agreement  shall inure to the benefit of and be  enforceable  by the  Employee's
personal or legal

                                       19



representatives,   executors,  administrators,   heirs,  distributees,  devises,
legatees  or  beneficiaries.  No  payment  pursuant  to any  will or the laws of
descent and  distribution  shall be made hereunder unless the Company shall have
been  furnished with a copy of such will and/or such other evidence as the Board
may deem necessary to establish the validity of the payment.

                  9.  Modification;  Waiver. No provisions of this Agreement may
be modified, waived or discharged unless such waiver,  modification or discharge
is agreed to in a writing signed by the Employee and such director or officer as
may be specifically  designated by the Board.  Waiver by any party of any breach
of or failure to comply with any provision of this  Agreement by the other party
shall not be construed as, or constitute, a continuing waiver of such provision,
or a waiver of any  other  breach  of, or  failure  to  comply  with,  any other
provision of this Agreement.
                  10.  Arbitration of Disputes.
                  (i) Any  disagreement,  dispute,  controversy or claim arising
out of or relating to this Agreement or the  interpretation  or validity  hereof
shall be settled exclusively and finally by arbitration except that in the event
of the  Employee's  breach of the covenant  contained  in Section 7 hereof,  the
Company 

                                       20




shall be entitled to seek injunctive relief pursuant to Section 7(ii) hereof. It
is  specifically  understood  and  agreed  that  any  disagreement,  dispute  or
controversy  which  cannot be resolved  between the parties,  including  without
limitation any matter relating to the  interpretation of this Agreement,  may be
submitted to arbitration  irrespective of the magnitude  thereof,  the amount in
controversy or whether such disagreement, dispute or controversy otherwise would
be  considered  justiciable  or  ripe  for  resolution  by a court  or  arbitral
tribunal.
                  (ii) The arbitration shall be conducted in accordance with the
Commercial   Arbitration  Rules  (the  "Arbitration   Rules")  of  the  American
Arbitration Association (the "AAA").
                  (iii) The arbitral  tribunal shall consist of one  arbitrator.
The parties to the  arbitration  jointly shall directly  appoint such arbitrator
within 30 days of  initiation of the  arbitration.  If the parties shall fail to
appoint such arbitrator as provided above, such arbitrator shall be appointed by
the AAA as  provided  in the  Arbitration  Rules and  shall be a person  who (a)
maintains  his  principal  place  of  business  within  30  miles of the City of
Fayetteville,   Arkansas,  and  (b)  has  had  substantial  experience  (whether
practical  or  academic)  in mergers and  acquisitions  or, if no such person is
available,  in employee

                                       21




benefits.  The Company  shall pay all of the fees,  if any, and expenses of such
arbitrator.
                  (iv) The arbitration shall be conducted within 30 miles of the
City of  Fayetteville,  Arkansas  or in such other city in the United  States of
America as the parties to the dispute may designate by mutual written consent.
                  (v) At any oral  hearing of  evidence in  connection  with the
arbitration,  each party  thereto or its legal  counsel  shall have the right to
examine its witnesses and to cross-examine  the witnesses of any opposing party.
No evidence of any  witness  shall be  presented  unless the  opposing  party or
parties shall have the opportunity to cross-examine such witness,  except as the
parties to the dispute otherwise agree in writing or except under  extraordinary
circumstances where the interests of justice require a different procedure.
                  (vi) Any decision or award of the arbitral  tribunal  shall be
final and binding upon the parties to the  arbitration  proceeding.  The parties
hereto hereby waive, to the extent  permitted by law, any rights to appeal or to
seek review of such award by any court or  tribunal.  The parties  hereto  agree
that the arbitral award may be enforced  against the parties to the  arbitration
proceeding  or their assets  wherever they may be found

                                       22


and that a judgment  upon the arbitral  award may be entered in any court having
jurisdiction.
                  (vii)  Nothing  herein  contained  shall be deemed to give the
arbitral  tribunal  any  authority,  power,  or right to alter,  change,  amend,
modify, add to, or subtract from any of the provisions of this Agreement.
                  11.  Notice.   All  notices,   requests,   demands  and  other
communications  required or  permitted  to be given by either party to the other
party  by  this  Agreement  (including,   without  limitation,   any  notice  of
termination  of  employment  and any notice  under the  Arbitration  Rules of an
intention  to  arbitrate)  shall be in writing  and shall be deemed to have been
duly given when  delivered  personally  or received by certified  or  registered
mail,  return receipt  requested,  postage prepaid,  at the address of the other

Either  party  hereto may change its address for  purposes of this Section 11 by

                  12.  Severability.  If any term or provision of this Agreement
or the application  thereof to any person or circumstance shall to any extent be
invalid or unenforceable,  the remainder of this Agreement or the application of
such term or provision to persons or circumstances  other than those as to which
it is held invalid or unenforceable shall not be affected thereby, and each term
and provision of this  Agreement  shall be valid and  enforceable to the fullest
extent permitted by law.

from any amounts payable to the Employee  hereunder all 

                                       24



federal,  state,  city or other taxes that the Company may reasonably  determine
are required to be withheld pursuant to any applicable law or regulation.
                  17.  Entire  Agreement.  Except  as  explicitly  provided  for
herein,  this Agreement  supersedes any and all other oral or written agreements
heretofore made relating to the subject matter hereof and constitutes the entire
agreement of the parties relating to the subject matter hereof;  provided, that,
this  Agreement  shall not supersede or limit or in any way affect the amount of
compensation or benefits to which the Employee would be entitled under any other
agreement,  plan,  program or  arrangement  with the Company  including any such
agreement,  plan, program or arrangement providing for benefits in the nature of
severance pay.
