               of Performance Contingent Units shall be established for minimum,
               target  and  maximum   attainment   of  such  goal.   The  actual

               period.  The Committee may designate that Performance  Contingent
               Awards shall be credited  with  Dividend  Equivalents  during the

               Stock on the first trading date of the Performance Period.

          (c)  After Performance Goals have been established,  they shall not be
               modified  in  respect  to the  Performance  Period to which  they
               relate.

          (a)  Following the end of a Performance  Period,  the Committee  shall
               ascertain and certify in writing  whether and the degree to which
               the   Performance   Goals  for  such  period  have  been  met.  A
               Participant shall be entitled to receive payment of an amount not
               exceeding   the  Fair  Market  Value  of  the  maximum  award  of
               Performance   Contingent  Units   established  by  the  Committee
               pursuant to Section 6 hereof  based upon the level of  attainment
               of  the  Performance  Goals  determined  by  the  Committee.  The
               Committee  shall  have the  authority  to reduce the award of any
               Participant  even if the Performance  Goals  attributable to such
               award  have been  met.  The  Committee  shall  have no  authority
               hereunder to increase any award calculated under this Plan.

          (b)  As soon as practicable  following  certification by the Committee
               pursuant to Section 7(a), payment of awards to Participants shall
               be made.  Payments  shall be made in cash,  shares of Stock or in
               shares of  Restricted  Stock as  prescribed  by the Committee and
               shall be  subject  to such  other  terms  and  conditions  as the
               Committee shall establish.

          (c)  Any   Restricted   Stock  issued  in  payment  of  a  Performance
               Contingent  Award  may not be  sold,  transferred,  or  otherwise
               disposed  of by the  Participant,  except  by will or the laws of
               descent  and  distribution,  for such period  established  by the
               Committee.  The Committee  shall have the authority to cancel all
               or any portion of any outstanding restrictions on such Restricted
               Stock  prior to the  expiration  of such period on such terms and
               conditions  as it may deem  appropriate.  During  the  restricted
               period the shares of Restricted  Stock shall be registered in the
               name of the Participant  and deposited with the Company,  and the
               Participant shall be entitled to vote such shares and receive any
               dividends with respect to such shares.

          (d)  Payment of any award of Dividend Equivalents shall be made at the
               same time as payment of the Performance Contingent Award to which
               it  relates  and  shall  be made in cash or  shares  of  Stock as
               prescribed by the Committee.

          (e)  The maximum  aggregate  dollar  value of  Performance  Contingent
               Units  and  Dividend  Equivalents  which  may be  awarded  to any
               Participant  for any  Performance  Period  shall  not  exceed  $1
               million.

8.       Election to Defer Payment

         (a)      A Participant  may, with  permission of the Committee elect to
                  defer  receipt of all or a specified  part of any  Performance
                  Contingent  Award and related  Dividend  Equivalents.  Such an
                  election  shall be subject to such terms and conditions as are
                  prescribed   by  the   Committee.   Deferral   elections   are
                  irrevocable and must be made during the time period and in the
                  manner prescribed by the Committee.

         (b)      The right of a  Participant  to receive any unpaid  portion of
                  any amount  deferred  hereunder  shall be an  unsecured  claim

9.       Adjustments in the Event of Change in Common Stock of the Company

         In the event of any change in the Stock of the Company by reason of any
         stock dividend, stock split, recapitalization,  reorganization, merger,
         consolidation,  split-up, combination, or exchange of shares, or rights
         offering to purchase Stock at a price  substantially  below Fair Market
         Value,  or of any similar  change  affecting  the Stock,  the number of
         Performance  Contingent  Units awarded which have not been paid and the
         number of  shares of Stock  which  may be  awarded  hereunder  shall be
         appropriately  adjusted  consistent  with such change in such manner as
         the Board in its discretion  may deem equitable to prevent  substantial
         dilution  or  enlargement  of the  awards  and  rights  granted  to, or
         available for Participants  hereunder.  Any fractional shares resulting
         from such adjustments shall be eliminated.

10.      No Right to an Award or Continued Employment

         (a)      Nothing contained in this Plan or in any resolution adopted or
                  to be adopted by the Board of Directors  will  constitute  the
                  granting  of an  award  hereunder.  The  granting  of an award
                  pursuant to the Plan will take place only when  authorized  by
                  the Committee.  No award and no rights of ownership thereunder
                  will be transferable otherwise than pursuant to Section 12.

         (b)      Nothing in the Plan shall  interfere  with or limit in any way
                  the  right  of the  Company  to  terminate  any  Participant's
                  employment at any time,  nor confer upon any  Participant  any
                  right to continue in the employ of the Company.

11.      Rights on Termination of Employment

         (a)      If a Participant in this Plan shall terminate  employment with
                  the  Company  on  account  of   Retirement  or  Disability  or
                  otherwise terminate employment with the written consent of the
                  Company prior to the expiration of any  Performance  Period(s)
                  in respect of which such  Participant  may be eligible  for an
                  award,  or if a subsidiary at which a Participant  is employed
                  shall cease to be a  subsidiary  of the  Company  prior to the
                  expiration of any Performance Period(s),  the award(s) paid to
                  such Participant shall be prorated  according to the number of
                  months of employment in each such Performance Period.

         (b)      A Participant whose employment terminates by dismissal with or
                  without  cause,  or  who  voluntarily   terminates  employment
                  without  consent  prior  to the  expiration  of a  Performance
                  Period, shall lose any right to receive payment of such award.


         (c)      In no event shall an award or a portion thereof the payment of
                  which has been  deferred  pursuant  to Section 8 be subject to
                  forfeiture.

12.      Death of a Participant

          (a)  A  Participant  may file  with  the  Corporate  Secretary  of the
               Company a designation of a beneficiary or beneficiaries on a form
               to be  provided by such  Participant,  which  designation  may be
               changed or revoked by the  Participant's  sole  action,  provided
               that  the  change  or  revocation  is filed  with  the  Corporate
               Secretary on a form provided by such Participant.  In case of the
               death  of  the  Participant,   before  or  after  termination  of
               employment, any earned but unpaid portion of an award to which he
               or she is  entitled  and  any  deferred  portions  of a  deceased
               Participant's  award shall be  delivered  to the  beneficiary  or
               beneficiaries  so  designated  or,  if no  beneficiary  has  been
               designated or survives such  Participant,  shall be delivered to,
               or  in  accordance  with  the  directions  of,  the  executor  or
               administrator of such Participant's estate.

          (b)  If a  Participant  shall die during a  Performance  Period,  such
               Participant's  beneficiary  shall only be entitled to receive the
               award declared for the  Performance  Period ending in the year of
               the Participant's death.

13.      Tax Withholding

         The Company  shall have the right to require  Participants  to remit to
         the  Company  an  amount  sufficient  to  satisfy  any tax  withholding
         requirements  or to deduct from any payments  made pursuant to the Plan
         amounts sufficient to satisfy tax withholding requirements.

14.      Termination and Modification

         (a)      The Committee  may at any time  terminate or from time to time
                  modify or suspend, and if suspended,  may reinstate any or all
                  of the provisions of this Plan except that no  modification of
                  this Plan may be made which will  adversely  affect any rights
                  or  obligations  with respect to any awards  theretofore  made
                  under the Plan.

         (b)      No  amendment  to the Plan shall be made  without  shareholder
                  approval if such approval is required in order for the Plan to
                  continue  to meet the  requirements  of Section  162(m) of the
                  Code and/or Rule 16b-3 of the  General  Rules and  Regulations
                  promulgated under the Securities Exchange Act of 1934.

15.      Change in Control

          (a)  In the event of a Change in  Control  of the  Company,  this Plan
               shall  continue to be binding upon the Company,  any successor in
               interest to the Company and all persons in control of the Company
               or  any  successor  thereto,  and no  transaction  or  series  of
               transactions  shall have the effect of reducing or canceling  the
               award of a Participant that has been declared but not paid unless
               consented to in writing by such affected Participant.

          (b)  As  soon  as  practicable   following  a  Change  in  Control,  a
               Participant  shall be paid a lump sum amount in cash equal to the
               aggregate value of the Performance  Contingent  Awards payable to
               the Participant for each of the Performance  Periods within which
               the date of the Change in Control  occurs,  calculated as to each
               such  Performance  Period  by  multiplying  the  award  that  the
               Participant would have earned on the last day of such Performance
               Period, assuming the achievement of each of the Performance Goals
               at the target level  established for such Performance  Period, by
               the  fraction  obtained by dividing the number of full months and
               any fractional  portion of a month during such Performance Period
               prior to the  change in  control  by the  total  number of months
               contained  in  such  Performance  Period.  For  purposes  of  the
               preceding  sentence,  the amount of cash  delivered in payment of
               the value of the  Performance  Contingent  Awards shall equal the
               number of Performance  Contingent  Units  constituting  such each
               such award  multiplied  by the  greater of (i) the  highest  Fair
               Market  Value per share of Stock at any time  during  the  60-day
               period  preceding  the Change in Control and (ii) if  applicable,
               the  price  of a share of Stock  which is paid or  offered  to be
               paid, by any person or entity, in connection with the transaction
               constituting  the Change in Control.  The amount  paid  hereunder
               shall be in lieu of any other awards  payable under this Plan for
               the  Performance  Periods  within  which the  Change  in  Control
               occurs.

          (c)  In the  event of a Change in  Control,  all  restrictions  on any
               outstanding shares of Restricted Stock issued pursuant to Section
               7 hereunder shall lapse as of the date of such Change in Control.

          (d)  As soon as practicable  following a Change in Control, any awards
               or Dividend  Equivalents  previously deferred by a Participant in
               accordance with Section 8 hereof,  plus interest  accrued thereon
               up until the date of payment, shall be paid in full.

16.      Unfunded Obligations; Trust Agreement

         (a)      The Company will pay from its general  assets all awards to be
                  made  hereunder.  However,  the Company may in its discretion,
                  establish a trust,  escrow agreement or similar arrangement in
                  order to aid the Company in meeting its obligations hereunder.

         (b)      Any  assets   transferred   by  the  Company   into  any  such
                  arrangement  shall  remain at all times  assets of the Company
                  and subject to the claims of the Company's  general  creditors
                  in the event of bankruptcy  or  insolvency of the Company.  No
                  security  interest  in  such  assets  shall  be  created  in a
                  Participant's favor and a Participant's rights under this Plan
                  and  under  any such  arrangement  shall be those of a general
                  unsecured creditor of the Company.

17.      Assignment and Alienation

         Benefits under this Plan may not be  anticipated,  assigned  (either at
         law or in equity), alienated, or subjected to attachment,  garnishment,
         levy, execution or other legal or equitable process. If any Participant
         or  beneficiary  under  this  Plan  becomes  bankrupt  or  attempts  to
         anticipate,  alienate,  sell,  transfer,  assign,  pledge,  encumber or
         charge  any  benefit  under  this  Plan,  such  benefit  shall,  in the
         discretion of the  Committee  cease and  terminate,  in which event the
         Committee  may hold or  apply  the  same or any  part  thereof  for the
         benefit of such Participant, his or her beneficiary,  spouse, children,
         other dependents or any of such individuals, in such manner and in such
         proportion as the Committee may deem proper.

18.      Effective Date and Termination of the Plan

         This Plan shall  become  effective as of January 1, 1994 subject to the
         approval of the  shareholders  at their annual meeting in 1995.  Unless
         earlier  terminated  by the  Committee  subject to Section 14, the Plan
         shall terminate on December 31, 1998. No Performance  Contingent  Award
         shall be made  pursuant to this Plan after the  termination  date,  but
         awards made prior to its termination date may extend beyond that date.
