                       NONQUALIFIED STOCK OPTION AGREEMENT

<TABLE>
<S>                      <C>
NONQUALIFIED STOCK       This option is not  intended to be an  incentive  stock
OPTION                   option under Section 422 of the Internal Revenue Code,
                         and it will be interpreted accordingly.

VESTING                  This option is only exercisable before it expires and
                         then only with respect to the vested portion of the
                         option. Subject to the preceding sentence, you may
                         exercise this option, in whole or in part, to purchase
                         a whole number of vested shares not less than 100
                         shares, unless the number of shares purchased is the
                         total number available for purchase under the option,
                         by following the procedures set forth in the Plan and
                         below in this Agreement.

                         Your right to purchase shares of Stock under this
                         option vests as to:

                         -- one-third (1/3) of the total number of shares
                         covered by this option, as shown on the cover sheet
                         (the "Option Shares"), on the first anniversary of the
                         Vesting Start Date ("Anniversary Date"), provided you
                         then continue in Service.

                         -- provided you then continue in Service, one-third
                         (1/3) of the Option Shares shall vest on the second
                         Anniversary Date.

                         -- provided you then continue in Service, one-third
                         (1/3) of the Option Shares shall vest on the third
                         Anniversary Date.

                         The resulting aggregate number of vested shares will be
                         rounded to the nearest whole number, and you cannot
                         vest in more than the number of shares covered by this
                         option.

TERM                     Your option will expire in any event at the close of
                         business at Company headquarters on the day before the
                         10th anniversary of the Grant Date, as shown on the
                         cover sheet. Your option will expire earlier if your
                         Service terminates, as described below.

REGULAR TERMINATION      If your Service  terminates for any reason,  other than
                         Death,  Disability,  Retirement, a Change in Control or
                         Termination by the Company with or without Cause,  then
                         your  option  will  expire at the close of  business at
                         Company   headquarters  on  the  90th  day  after  your
                         termination  date.  Any and all  unvested  options  are
                         forfeited as of your date of termination.

TERMINATION WITHOUT      If your service is terminated by the Company without
CAUSE                    Cause, then your vested options shall expire at the
                         close of business one (1) year
</TABLE>

<TABLE>
<S>                      <C>
                         after your termination date.  Any and all  unvested
                         options are  forfeited as of your date of termination.

TERMINATION FOR          If  your  Service  is  terminated  by the  Company  for
CAUSE                    Cause,  then you shall  immediately  forfeit all rights
                         to  your  option  and  the  option  shall   immediately
                         expire.

DEATH                    If your Service terminates because of your death, then
                         your option will expire at the close of business at
                         Company headquarters on the date 36 months after the
                         date of death. During that 36 month period, your estate
                         or heirs may exercise the vested portion of
                         your option.

DISABILITY               If your Service terminates because of your permanent
                         and total disability, then your option will continue to
                         vest as if your Service had not terminated and will
                         expire at the close of business at Company headquarters
                         on the day before the 10th anniversary of the Grant
                         Date, as shown on the cover sheet.

LEAVES OF ABSENCE        For  purposes of this  option,  your  Service  does not
                         terminate  when you go on a bona fide employee leave of
                         absence  that was  approved  by the Company in writing,
                         if  the  terms  of  the  leave  provide  for  continued
                         Service crediting,  or when continued Service crediting
                         is required by applicable  law.  However,  your Service
                         will be treated as  terminating  90 days after you went
                         on  employee  leave,  unless  your  right to  return to
                         active  work  is  guaranteed  by law or by a  contract.
                         Your Service  terminates in any event when the approved
                         leave  ends  unless  you  immediately  return to active
                         employee work.

                         The Company determines, in its sole discretion, which
                         leaves count for this purpose, and when your Service
                         terminates for all purposes under the Plan.

RETIREMENT               If your service  terminates  due to Normal  Retirement,
                         defined  as  retirement  at or after  age 65,  or Early
                         Retirement,  defined as retirement at age 55 through 64
                         with at  least  three  (3)  years of  service  with the
                         Company,  your  option  will  expire  at the  close  of
                         business  at Company  headquarters  on the date that is
                         the  earlier  of three  (3)  years  from  your  date of
                         retirement and the 10th  Anniversary of the Grant Date,
                         as  shown  on the  cover  sheet.  Any and all  unvested
                         options as of your date of retirement are forfeited.

NOTICE OF EXERCISE       When you wish to exercise this option, you must notify
                         the Company's designated agent filing in the manner and
                         form permitted by the designated agent.

                         If someone else wants to exercise this option after
                         your death, that person must prove to the Company's
                         satisfaction that he or she is

FORM OF PAYMENT          When you submit your notice of  exercise, you must
                         include payment of the option price  for the shares you
                         are purchasing. Payment may be made in one (or a
                         combination) of the following forms:

                         - Cash, your personal check, a cashier's check, a money
                         order or another cash equivalent acceptable to the

                         to the Company. The value of the shares, determined as
                         of the effective date of the option exercise, will be
                         applied to the option price.

                         - By delivery (on a form prescribed by the Company or

                         licensed securities broker acceptable to the Company to
                         sell Stock and to deliver all or part of the sale
                         proceeds to the Company in payment of the aggregate
                         option price and any withholding taxes (if approved in
                         advance by the Compensation Committee of the Board if
                         you are either an executive officer or a
                         director of the Company).

WITHHOLDING TAXES        You will not be allowed to exercise this option unless
                         you make acceptable arrangements to pay any withholding
                         or other taxes that may be due as a result of the
                         option exercise or sale of Stock acquired under this
                         option. In the event that the Company determines that
                         any federal, state, local or foreign tax or withholding
                         payment is required relating to the exercise or sale of
                         shares arising from this grant, the Company shall have
                         the right to require such payments from you, or
                         withhold such amounts from other payments due to you
                         from the Company or any Affiliate.

TRANSFER OF OPTION       Except  as  provided  in  this  section,   during  your
                         lifetime,  only you  (or,  in the  event of your  legal
                         incapacity  or  incompetency,  your  guardian  or legal
                         representative)   may  exercise  this  option  and  the
                         option shall not be assignable or  transferable by you,
                         other than by designation of  beneficiary,  will or the
                         laws of  descent  and  distribution.  You may  transfer
                         all or part  of this  option,  not  for  value,  to any
                         Family Member,  provided that you provide prior written
                         notice to the Company,  in a form  satisfactory  to the
                         Company,  of such  transfer.  For the  purpose  of this
                         section,  a "not  for  value"  transfer  is a  transfer
                         which is (i) a gift,  (ii) a transfer  under a domestic
                         relations  order  in  settlement  of  marital  property

                         than fifty  percent of the voting  interests  are owned
                         by Family  Members (or you) in exchange for an interest
                         in that entity.  Subsequent  transfers  of  transferred
                         options are  prohibited  except to your Family  Members
                         in accordance  with this section or by will or

                         the laws of   descent   and  distribution. The events
                         of termination of the Service  this   Agreement   shall
                         continue to be applied with  respect to you,  following
                         which  the   option   shall  be   exercisable   by  the
                         transferee  only to the  extent,  and  for the  periods
                         specified in herein.

RETENTION RIGHT          Neither your option nor this Agreement gives you the
                         right to be retained by the Company (or any Parent,
                         Subsidiaries or Affiliates) in any capacity. The
                         Company (and any Parent, Subsidiaries or Affiliates)
                         reserves the right to terminate your Service at any
                         time and for any reason.

SHAREHOLDER RIGHTS       You, or your designated beneficiary, estate or heirs,
                         have no rights as a shareholder of the Company until a
                         certificate for your option's shares has been issued
                         (or an appropriate book entry has been made). No
                         adjustments are made for dividends or other rights if
                         the applicable record date occurs before your stock
                         certificate is issued (or an appropriate book entry
                         has been made), except as described in the Plan.

FORFEITURE OF RIGHTS     The  Company  at any time shall have the right to cause
                         a  forfeiture  of your  rights on account of you taking
                         actions  in  competition   with  the  Company.   Unless
                         otherwise   specified   in  an   employment   or  other
                         agreement   between  the  Company  and  you,  you  take
                         actions  in   competition   with  the  Company  if  you
                         directly or indirectly  own any interest in,  operates,
                         joins,   controls   or   participates   as  a  partner,
                         director,  principal, officer, or agent of, enters into
                         the   employment  of,  acts  as  a  consultant  to,  or
                         performs  any  services   for,  any  entity  which  has
                         material  operations which compete with any business in
                         which  the  Company  or  any  of  its  Subsidiaries  is
                         engaged during your  employment with the Company or any
                         of its  Affiliates  or at the time of your  termination
                         of Service.

ADJUSTMENTS              In the event of a stock split, a stock dividend or a
                         similar change in the Stock, the number of shares
                         covered by this option and the option price per share
                         shall be adjusted (and rounded down to the nearest
                         whole number) if required pursuant to the Plan. Your
                         option shall be subject to the terms of the agreement
                         of merger, liquidation or reorganization in the event
                         the Company is subject to such corporate activity.

APPLICABLE LAW           This Agreement will be interpreted and enforced under
                         the laws of the State of Indiana, other than any
                         conflicts or choice of law rule or principle that

<TABLE>

RESTRICTED STOCK/          This grant is an award of Stock in the number of
NONTRANSFERABILITY         shares set forth on the cover sheet, at the purchase
                           price set forth on the cover sheet, and subject to
                           the vesting conditions described below ("Restricted
                           Stock"). The purchase price for the Restricted Stock
                           is deemed paid by your services to the Company. To
                           the extent not yet vested, your Restricted Stock may
                           not be transferred, assigned, pledged or
                           hypothecated, whether by operation of law or
                           otherwise, nor may the Restricted Stock be made
                           subject to execution, attachment or similar
                           process.

ISSUANCE AND VESTING       The Company will issue your Restricted Stock in your
                           name as of the Grant Date.

                                 Your rights to the shares of Stock under this
                           grant vest as to:

                                 -- one-third (1/3) of the total number of
                           shares covered by this grant, as shown on the cover
                           sheet (the "Shares"), on the third anniversary of the
                           Grant Date ("Anniversary Date"), provided you then
                           continue in Service.

                                 -- provided you then continue in Service,
                           one-third (1/3) of the Shares shall vest on the
                           fourth Anniversary Date.

                                 -- provided you then continue in Service,
                           one-third (1/3) of the Shares shall vest on the fifth
                           Anniversary Date.

                           The resulting aggregate number of vested shares will
                           be rounded to the nearest whole number, and you
                           cannot vest in more than the number of shares covered
                           by this grant.

                           No additional shares of Stock will vest after your
                           Service has terminated for any reason.

FORFEITURE OF UNVESTED     In the event that your Service terminates for any
STOCK                      reason, you will forfeit to the Company all of the
                           shares of Stock subject to this grant that have not
                           yet vested.

ESCROW                     The certificates for the Restricted Stock shall be
                           deposited in escrow with the Secretary of the Company
                           to be held in accordance with the provisions of this
                           paragraph. Each deposited certificate shall be
                           accompanied by a duly executed Assignment Separate
                           from Certificate in the form attached hereto as
                           Exhibit A. The deposited certificates shall remain in
                           escrow until such time or times as the certificates
                           are to be released or otherwise surrendered for
                           cancellation as discussed below. Upon delivery of the
                           certificates to the Company, you shall be issued an
                           instrument of deposit acknowledging the number of
                           shares

                           of Stock delivered in escrow to the Secretary of the
                           Company.

                           All regular cash dividends on the Stock (or other
                           securities at the time held in escrow) shall be paid
                           directly to you and shall not be held in escrow.
                           However, in the event of any stock dividend, stock
                           split, recapitalization or other change affecting the
                           Company's outstanding common stock as a class
                           effected without receipt of consideration or in the
                           event of a stock split, a stock dividend or a similar
                           change in the Company Stock, any new, substituted or
                           additional securities or other property which is by
                           reason of such transaction distributed with respect
                           to the Stock shall be immediately delivered to the
                           Secretary of the Company to be held in escrow
                           hereunder, but only to the extent the Stock is at the
                           time subject to the escrow requirements hereof.

                           As your interest in the shares vests, as described
                           above, the certificates for such vested shares shall
                           be released from escrow and delivered to you, at
                           your request, within 30 days of their vesting.

WITHHOLDING TAXES          You agree, as a condition of this grant, that you
                           will make acceptable arrangements to pay any
                           withholding or other taxes that may be due as a
                           result of the vesting of Stock acquired under this
                           grant.  In the event that the Company determines
                           that any federal, state, local or foreign tax or
                           withholding payment is required relating to the
                           vesting of shares arising from this grant, the
                           Company shall have the right to require such
                           payments from you, or withhold such amounts from
                           other payments due to you from the Company or any
                           Affiliate.

SECTION 83(b) ELECTION     Under Section 83 of the Internal Revenue Code of
                           1986, as amended (the "Code"), the difference between
                           the purchase price paid for the shares of Stock and
                           their fair market value on the date any forfeiture
                           restrictions applicable to such shares lapse will be
                           reportable as ordinary income at that time. For this
                           purpose, "forfeiture restrictions" include the
                           forfeiture of unvested Stock that is described above.
                           You may elect to be taxed at the time the shares are
                           acquired, rather than when such shares cease to be
                           subject to such forfeiture restrictions, by filing an
                           election under Section 83(b) of the Code with the
                           Internal Revenue Service within thirty (30) days
                           after the Grant Date. You will have to make a tax
                           payment to the extent the purchase price is less than
                           the fair market value of the shares on the Grant
                           Date. No tax payment will have to be made to the
                           extent the purchase price is at least equal to the
                           fair market value of the shares on the Grant Date.
                           The form for making this election is attached as
                           Exhibit B hereto. Failure to make this filing within
                           the thirty (30) day period will result in the
                           recognition of ordinary income by you (in the event
                           the fair market value of the shares as of the vesting
                           date exceeds the purchase price) as the forfeiture
                           restrictions lapse.

                           AND NOT THE COMPANY'S, TO FILE A TIMELY ELECTION
                           UNDER SECTION 83(b), EVEN IF YOU REQUEST THE COMPANY
                           OR ITS REPRESENTATIVES TO MAKE THIS FILING ON YOUR
                           BEHALF. YOU ARE RELYING SOLELY ON YOUR OWN ADVISORS

                           or Affiliates) in any capacity. The Company (and any
                           Parent, Subsidiaries or Affiliates) reserves the

SHAREHOLDER RIGHTS         You have the right to vote the Restricted Stock and

                           any stock split, stock dividend, combination of
                           shares or other similar transaction shall be deemed
                           to be a part of the Restricted Stock and subject to
                           the same conditions and restrictions applicable
                           thereto. The Company may in its sole discretion
                           require any dividends paid on the Restricted Stock to
                           be reinvested in shares of Stock, which the Company
                           may in its sole discretion deem to be a part of the
                           shares of Restricted Stock and subject to the same
                           conditions and restrictions applicable thereto.
                           Except as described in the Plan, no adjustments are
                           made for dividends or other rights if the applicable
                           record date occurs before your
                           stock certificate is issued.

FORFEITURE OF RIGHTS       If you should take actions in competition with the
                           Company, the Company shall have the right to cause a
                           forfeiture of your unvested Restricted Stock, and
                           with respect to those shares of Restricted Stock
                           vesting during the period commencing twelve (12)
                           months prior to your termination of Service with the
