       between the degree to which Performance Goals are attained over the
       term of the Performance Period and the Payout as a percent of the
       Target Incentive Award.  The Performance Payout Formula will vary by
       Performance Goal, as designated by the Committee at the beginning of

       150% of the original Target Incentive Award.

       Goals in a Performance Period of relative importance and influence on
       the Payout.  For example, one Performance Goal may be weighted at 40%

       determined by achievement of the first Performance Goal.

  2.2  Gender and Number.  Except when otherwise indicated by the context,
any masculine terminology used herein shall also include the feminine, and

SECTION 3  ELIGIBILITY AND PARTICIPATION
           -----------------------------

  3.1  Eligibility and Participation.  Eligibility for participation in the
Plan shall be limited to those Employees grade 45 and above who, by the
nature and scope of their position, regularly and directly make, influence,
or implement policy decisions which significantly impact the overall long-
term results or success of the Company.  Specific criteria for participation
will be determined by the Committee prior to the beginning of each
Performance Period and nominations for participation in accordance with
such criteria will be reviewed by the Committee at the beginning of each 
Performance Period.  Employees approved for participation shall be
notified of their selection as soon as practical following approval.

  3.2  Termination of Employment.  No Payout shall be made for a Performance
Period for a Participant whose employment with the Company is terminated
during the Performance Period for reasons other than death, Layoff, 
Retirement, or Disability, unless his termination was due to a cause
approved by the Committee.  In the event of termination of employment for
reasons of death, Layoff, Retirement, or Disability, or an approved cause,
a prorated payment may be made on the basis of the Participant's actual
employment and achievement of Performance Goals during the Performance
Period, as determined by the Committee at its sole discretion.

  3.3  No Rights Conferred.  Selection for participation in the Plan in any
one Performance Period shall not confer on the Participant the right to 
participate in the Plan for any other Performance Period.  Furthermore, 
nothing in the Plan or in any Award under the Plan shall confer on any
Participant any right to continue in the employ of the Company or
affect the right of the Company to terminate a Participant's employment
at any time.

SECTION 4  AWARD GRANTS AND PAYOUT DETERMINATION
           -------------------------------------

  4.1  Award Grants.  The Committee in its sole discretion may grant Awards
to eligible Participants on an annual basis.  It is intended that Performance
Periods will overlap.  However, Awards do not necessarily have to be granted
on an annual basis.  Awards will be earned by Participants during the
Performance Period if and to the extent the Performance Goals are met.

  4.2  Establishment of Performance Goals, Weightings, and Performance Payout
Formulas.  In advance of each Performance Period, the Committee shall
establish the appropriate Performance Goals, Weightings, and
Performance Payout Formulas for purposes of the Plan.  Performance Goals,
Weightings, and Performance Payout Formulas may vary by Participant in
the Plan and Performance Period.  The degree to which Awards are earned
by achievement of one Performance Goal shall have no direct effect on
the determination of Awards earned by achievement of other Performance
Goals.  To establish the Performance Goals, Weightings, and Performance
Payout Formulas for each Performance Period, the Committee will use any
information it considers relevant regarding the likely performance of
the Company.  The Performance Goals, Weightings, and Performance Payout
Formulas will be communicated to Participants as soon as practicable
following their determination by the Committee.  If during a Performance 
Period the Committee determines a change in the Company's business,
operations, corporate or capital structure, the manner in which it conducts
business or any other change to be extraordinary and material and determines
that, as a result of such change, the established Performance Goals,
Weightings, and Performance Payout Formulas are no longer appropriate, the
Committee may make modifications as it deems appropriate and equitable in the
Committee's sole and absolute discretion.

  4.3  Assignment of Target Incentive Awards.  For each Performance Period,
the Committee shall determine and assign the Target Incentive Award for each
Participant.  Such determination shall be based on the assessed impact the
Participant's position exerts on overall Company results.

  4.4  Determination of Payouts.  Payouts may vary above and below the Target
Incentive Awards as determined in Section 4.2 preceding, dependent 
upon the achievement of the established Performance Goals, in accordance with
the Weightings and Performance Payout Formulas prescribed by the Committee.
The Payouts on behalf of a non-officer or a Participant below the level of
Senior Vice President must be approved by the Committee.  Payment of the 
Payout on behalf of the Chief Executive Officer and any other Participant who
is a Senior Officer of the Company will be approved by the Board.  The
Committee's determination of the Payouts shall be final, binding, and
conclusive.





  4.5  Limitation on Amounts Available for Payouts.  The aggregate amount
available each Plan Year for Payouts shall be limited to 3% of annual
net income of the Company.  The Committee may, at its discretion, set
any limit on the aggregate dollar amount available for Payouts during
any Performance Period.  To the extent Payouts need to be limited in a
Performance Period, Awards will be reduced on a prorated basis.

SECTION 5  PAYOUT
           ------

  5.1  Payout.  A Participant's Payout shall be paid to the Plan Agent on
behalf the Participant no later than 90 days after publication of the
Company's audited financial statements reflecting the last fiscal year
of the Performance Period (the "Payout Date") and, subject to Sections
5.3 and 5.5, shall be applied by the Plan Agent to the purchase of
Stock in accordance with Section 7.3.

  5.2  Payment on Death, Layoff, Disability, and Retirement.  Prorated
payments that are made pursuant to Section 3.2 shall be paid to the
Plan Agent on behalf of the Participant, or in the event of death, on
behalf of the Participant's Beneficiary, as soon as practicable after
termination of employment.  The payments to be prorated shall be
restricted to those payable for the performance cycle ending with the
calendar year in which the employee terminates employment.  Prorated
payments, subject to Section 5.5, shall be applied by the Plan Agent
to the purchase of Stock in accordance with Section 7.3.

  5.3  Deferral of Payouts.  Notwithstanding any provisions of the Plan
to the contrary, Payouts may be deferred at the election of the 
Participant in accordance with the applicable provisions of the 
Company's Deferred Compensation Plan.  In the event of such election,
all aspects of Payouts shall be governed by the applicable provisions
of the Company's Deferred Compensation Plan.

  5.4  Payment Upon Change in Control.  In the event of a Change in Control
of the Company, each Award theretofore granted will be paid by the
Company in cash directly to the Participants in a prorated amount
based on performance to date as designated by the Committee in its
sole and absolute discretion.  Payments shall be made within 60 days
of the Change in Control of the Company.

  5.5  Maximum Number of Shares: Stockholder Approval.  The aggregate number
of shares of Stock purchased by the Plan Agent on behalf of
Participants who are officers (within the meaning of Section 16(b) of
the Securities Exchange Act of 1934, as amended) ("Officers") shall
not exceed 1,500,000.  In the event that prior to the first Payout
Date under the Plan the Plan has not been approved by the stockholders
of the Company, or the Plan Agent has purchased the maximum number of
shares of Stock available under the Plan, all Payouts for Participants
who are Officers shall be paid in the form of cash paid directly to
the Participant or Participant's Beneficiary.









SECTION 6  DESIGNATION OF BENEFICIARIES
           ----------------------------

     A Participant may designate a Beneficiary or Beneficiaries who in the
event of the Participant's death are to receive the Stock that otherwise
would have been delivered to the Participant.  All designations shall be
in writing and shall be effective only if and when delivered to the Committee
during the lifetime of the Participant.  A Participant may, from time to time
during his lifetime, change his Beneficiary or Beneficiaries by a written
instrument delivered to the Committee.  If a Participant designates a
Beneficiary without providing in the designation that the Beneficiary
must be living at the time of each Payout, the designation shall vest in the
Beneficiary all of the Payouts whether payable before or after the
Beneficiary's death, and any Payouts remaining upon the Beneficiary's 
death shall be made to the Beneficiary's estate.  In the event a 
Participant shall not designate a Beneficiary or Beneficiaries as 
aforesaid, or if for any reason such designation shall be ineffective, 
in whole or in part, the Stock that otherwise would have been delivered 
to such Participant shall be paid to the Participant's beneficiary as 
designated by the Participant in the Company's group life insurance 
program.  In the event the Participant's beneficiary as designated in
the Company's group life insurance program is ineffective, in whole or
in part, the Stock shall be delivered to the Participant's estate and in
such event the term "Beneficiary" shall include his estate.
