REQUESTED TO COMPLETE, SIGN AND RETURN  THE ENCLOSED PROXY CARD PROMPTLY IN  THE

                                   PROPOSAL 1
                             ELECTION OF DIRECTORS
 
     The Board of Directors currently consists of twelve directors, divided into
three classes. Each class is elected to serve a three year term, and classes are
elected on a staggered basis. Under  the Board's current retirement policy,  the
Board  will consist of eleven directors when Mr. Ashe completes his service as a
director at the  Company's 1996 Annual  Meeting. The number  of directors to  be
elected  at the  1996 Annual Meeting  is fixed  at three. The  directors who are
nominated for  election by  the  shareholders at  the  1996 Annual  Meeting  are
Messrs. Hohn, Samuel and Wesson.
 
     All  of the nominees  were elected by  the shareholders at  the 1993 Annual
Meeting for a three year term. Messrs.  Hohn, Samuel and Wesson will be  elected
to  hold office until the Annual Meeting of  Shareholders to be held in 1999, or
until their successors are elected and  qualify. Under Delaware law, a  director
elected  to fill a  vacancy on the Board  serves until the  next election of the
class for which the director shall have been chosen.
 
     Unless otherwise  specified, the  proxies received  will be  voted FOR  the
election of the listed nominees.
 
     The nominees for director, their present principal occupation or employment
as of March 1, 1996, and other positions held during the past five years are set
forth below.

1994 Deferred Compensation Plan
 
     The  Board of  Directors adopted the  1994 Deferred  Compensation Plan (the
'Deferred Plan') to provide certain employees with the opportunity to defer some
or all of the base salary and/or bonus otherwise payable to them by the Company.
An employee who is a participant  in either the Officers' Annual Incentive  Plan
or  the Management  Incentive Plan  is eligible  to participate  in the Deferred
Plan. Amounts deferred for 1996 can either earn interest at an annual rate equal
to the  yield quotation  as of  the end  of the  calendar quarter  for the  U.S.
Treasury  10-year  note or  be converted  into phantom  shares of  the Company's
Common Stock which will earn additional  phantom shares on each day the  Company
pays  a  dividend.  Deferred  account  balances  are  payable  in  cash  and are
distributed at the election of the participant in a lump sum or installments  at
the  time specified by the  participant or at retirement  or termination. In the
event of a change in control, as defined in the Deferred Plan, deferred  account
balances  are paid in cash and are distributed  not later than 15 days after the
date of the change in control.

(1) Each  option was granted on June 1, 1995 to purchase shares of the Company's
    $5.00 par value Common  Stock. Twenty percent of  the shares subject to  the
    options  become exercisable one year  from the date of  grant and 20% become
    exercisable on  each  of the  four  succeeding anniversaries,  provided  the
    optionee continues to be employed by the Company or any of its subsidiaries.
    Only  those options exercisable as of the date of the optionee's termination
    may be exercised during the 90  day period following such termination  date;
    however,  upon termination by (i) early  or normal retirement, (ii) death or
    (iii) disability any  option not then  exercisable shall become  immediately
    exercisable  and shall be exercisable during the three year period following
    such termination; provided  that in  no event shall  options be  exercisable
    after the expiration of 10 years from the date of grant. The actual value an
    optionee  receives is dependent on future  stock market conditions and there
    can be no assurance that the amounts reflected in the right hand columns  of
    the  table will actually  be realized. No  gain to the  optionee is possible
    without an appreciation in stock  value which will benefit all  shareholders
    commensurately.

                             Certain Benefit Plans
 
Defined Benefit Pension Plan
 
     The  Company currently  has a  qualified, non-contributory  defined benefit
plan, the Witco Corporation Retirement Plan, which covers executive officers and
non-bargaining employees. Because the pension  plan was sufficiently funded,  no
contributions  were made thereto  in 1995. The remuneration  covered by the plan
represents the base salary plus commissions.
 
     Under the pension plan, a normal retirement benefit is based on (a) 1.5% of
the individual's final average earnings (average  base salary for the 60  months
preceding  retirement using 1992 base salary for years prior to 1992) multiplied
by years of  credited service, reduced  by (b) 1.5%  of the individual's  Social
Security  benefit at  retirement multiplied by  years of credited  service (to a
maximum of 50%  of the Social  Security benefit). Pension  benefits will not  be
less than the amount accrued as of December 31, 1993 under the pre-amended plan.

<PAGE>
<PAGE>
     To  the  extent  that  benefits  under  the  qualified  plan  exceed limits
established by the Internal Revenue Code of 1986, as amended (the 'Code'),  they
are  payable  under  the  Excess  Benefit and  Compensation  Cap  Plan  of Witco
Corporation (the 'Excess Plan')  which provides for the  payment of benefits  in
excess  of  certain  limitations  imposed  by  the  provisions  of  the Employee
Retirement Income Security Act of 1974, as amended ('ERISA'), or limitations  on
compensation or benefits that may be imposed by the Code.
 
     The following table illustrates the estimated annual benefits payable to an
employee,  including those named  in the Summary Compensation  Table on page 11,
under  the  qualified  and  excess  plans.  These  estimates  assume   continued
employment  until the normal  date of retirement at  age 65, and  are based on a
straight-life annuity form of retirement income. Amounts shown in the table will
be reduced by the Social Security offset.

Supplemental Executive Retirement Plan
 
     The  Company has a Supplemental Executive  Retirement Plan (the 'SERP') and
participants in the  plan are or  have been corporate  officers selected by  the
Board  of Directors. The  SERP supplements coverage  under the Company's pension
plan and provides a participant, who retires at or after age 65, with 50% of his
average base salary plus average bonus (base salary is averaged over three years
preceding retirement, and  bonus is  the average  of the  three highest  bonuses
awarded  in  the 60  months preceding  retirement) less  amounts paid  under the
pension plan, the Excess Plan and 50% of Social Security benefit.
 
     Estimated annual  target retirement  benefits  under all  Retirement  Plans
including the Supplemental Executive Retirement Plan, payable as a 50% Joint and
Survivor  annuity or  15 year certain  annuity (if  unmarried) at age  65 are as
follows, assuming future  base salary and  bonus remain at  current levels:  Mr.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     During the  fiscal  year ended  December  31, 1995,  the  Organization  and
Compensation  Committee (the 'Committee')  was composed of  Messrs. Ashe, Burns,
Grant, Hohn and Samuel. All members  of the Committee participated in  decisions
related to compensation of the Company's executive officers.
 
     Prior  to his  retirement in  May 1986,  Mr. Ashe  was President  and Chief
Operating Officer of the Company.
 
     Mr. Hohn is Chairman of the Board  and Chief Executive Officer of New  York
Life Insurance Company. This firm has issued guaranteed investment contracts for
Witco's  Employee Retirement Savings  Plan in the past  and may provide services
during 1996.
 
     No executive officer of  the Company served  as a director  or member of  a
compensation committee of another entity, one of whose executive officers served
as a director or on the Committee of the Company.
 
             REPORT OF THE ORGANIZATION AND COMPENSATION COMMITTEE
 
     This  report  describes  the  role  of  the  Organization  and Compensation
Committee and  provides  an overview  of  the Company's  executive  compensation
philosophy. The report also describes how the executive compensation program was
administered  in  1995  with  specific  emphasis  on  the  Committee's decisions
affecting the compensation of the Chief Executive Officer.
 
THE COMMITTEE'S ROLE
 
     The Committee reviews and approves each element of the Company's  executive
compensation  program and periodically assesses the effectiveness of the program
as a whole.  This program  covers the chief  executive officer,  the four  other
named  executive  officers, and  all other  executive  officers of  the Company.
Specifically, the Committee  approves the  salaries of  all executive  officers,
cash awards under the Company's Officers' Annual Incentive Program, the grant of
stock  options under the  Stock Option Plans,  and the provision  of any special
benefits or perquisites to executive officers. In addition to approving salaries
and grants for  individual executive  officers, the Committee  also reviews  the
aggregate  expenditure of funds for cash incentives, the aggregate allocation of
shares for proposed stock option and long term incentive plans, and the  ongoing
operation  of the executive  compensation program described  above. In addition,
the Committee periodically reviews the design of each component of the executive
compensation program  and  considers  alternatives which  may  better  meet  the
Company's objectives.
 
     To  carry  out  its  responsibilities,  the  Committee's  five non-employee
directors met six times during 1995.

OBJECTIVES OF THE EXECUTIVE COMPENSATION PROGRAM
 
     The two  principal  objectives  of  the  Company's  executive  compensation
program are to:
 
           -- Provide  competitive  total compensation  opportunities  that will
              serve to attract  and retain highly  qualified executives who  can
              achieve the long-term financial and strategic goals of the Company
              and produce increased value for shareholders.
 
           -- Provide  a comprehensive compensation program which emphasizes the
              pay-for-performance  philosophy  of  the  Company  by  integrating
              executive  compensation with short and long-term performance goals
              of the  Company and  its  key business  units and  rewarding  each
              executive's individual initiative and achievements.
 
     With respect to the first objective, it is the Committee's intention to set
total  compensation opportunity levels  which are competitive  with a comparison
group  of   chemical   and  petroleum   product   companies  and   other   major
publicly-traded  companies  of  similar  size  and  complexity  (the 'Comparison
Group') because the Committee  believes that the  relevant market for  executive
talent  is broader than those companies  against which it directly competes. The
Committee regularly reviews information derived from various sources,  including
proxy statements, industry surveys, and external compensation consultants. Thus,
the companies included in the Comparison Group are not the same as the companies
represented  in the  published industry indexes  in the  Comparison of Five-Year
Cumulative Total Return graph included in this Proxy Statement.
 
     The Committee examines specific salary and incentive target recommendations
for each  executive officer  based on  the requirements,  responsibilities,  and
specific goals for each position. In general, it is the Committee's intention to
target  base  salary, incentive  compensation, and  stock  option grants  to the
median compensation levels of the Comparison Group when the Company is operating
at fully acceptable levels of performance.
 
     With respect to the second objective, the Company's executive  compensation
programs  are designed to place a  significant portion of the total compensation
opportunity at risk. The three principal  incentive programs of the Company  for
1995,  the existing Officers' Annual Incentive Program ('OAIP') and the 1995 and
1992 Stock Option Plans ('SOPs'), use different performance measures and periods
to create a  significant variable  opportunity linking total  compensation to  a
broad range of performance parameters.
 
     It  is the  general intention  of the Committee  to attempt  to assure that
executive compensation  will  meet  the  requirements  for  deductibility  under
Section  162(m)  of  the  Code.  That  provision  establishes  a  limit  on  the
deductibility of  annual  compensation  for  certain  executive  officers  which
exceeds  $1,000,000.  The Committee  has  directed the  Company's  management to
review executive compensation  arrangements and  employee benefit  plans with  a
view  to determining  the procedures and  changes necessary to  comply with this
provision of the Code.  The Long Term Incentive  Plan that the stockholders  are
being asked to approve at the Annual Shareholders Meeting has been structured to
comply  with such  provisions of the  Code. However, the  Committee reserves the
right,  under  appropriate  circumstances   and  where  merited  by   individual
performance, to nevertheless authorize compensation payments which may not, in a
specific case, be fully deductible by the Company.
 
OVERVIEW OF EXECUTIVE COMPENSATION AND 1995 COMMITTEE ACTIONS
 
     As  indicated above, the Company's  existing executive compensation program
has three principal components:  base salary, annual  cash incentives under  the
OAIP, and stock options under the SOPs.
 
                                       16
 
<PAGE>
<PAGE>
The  Committee's decisions and actions during 1995 with respect to each of these
components are discussed below.
 
THE BASE SALARY PROGRAM
 
     The base salary program is intended to provide base salary levels that  are
externally   competitive  and   internally  equitable,   and  to   reflect  each
individual's sustained performance and  cumulative contribution to the  Company.
The  current salary of each executive officer  is compared to salary surveys and
proxy statement data for similar  positions having approximately the same  scope
of  responsibility.  Each  executive officer's  individual  performance  is then
reviewed to arrive at merit  increase determinations. These merit increases  are
then reviewed within the context of the total merit increase budget to determine
reasonableness.  In 1995, merit  increases for individual  executive officers of
the Company ranged  from 2.74%  to 10.17% of  base salary  producing an  average
merit increase of 5.35% for all executive officers of the Company. This analysis
is  necessarily a  subjective process  which utilizes  no specific  weighting or
formula with respect to the described  factors in determining the base  salaries
of executive officers.
 
THE OFFICERS' ANNUAL INCENTIVE PROGRAM
 
     The  OAIP provides for annual cash  incentive compensation based on various
performance measures  for executive  officer positions.  Bonus awards  are  paid
under  the OAIP only  if performance exceeds  a predetermined performance target
reflecting minimally acceptable performance. The  minimum or threshold level  of
performance, which provides a basic award of 50% of the target payout, is set at
80% of the performance target. If actual results fall short of this threshold no
incentive  compensation is paid to executive  officers. Target payouts under the
plan are made if fully acceptable  performance is achieved. Maximum payouts  can
exceed  target payouts by 50%  or more if outstanding  levels of performance are
achieved.
 
     For Management  Committee members  (which include  four of  the five  named
executive  officers,  one of  whom  is the  chief  executive officer),  the most
important performance  criterion is  the achievement  of an  earnings per  share
('EPS')  target.  An  annual EPS  target  is  recommended by  the  Committee and
approved annually  by the  entire  Board for  strategic and  financial  planning
purposes. By setting EPS targets at levels which will be difficult to reach, the
Committee assures that executive pay is truly at risk and that compensation will
bear  a strong relationship  to corporate performance.  Primary EPS (the primary
performance measure  for  OAIP  awards  for  Management  Committee  members)  is
adjusted   by  a  'supplementary  performance   multiplier'  determined  by  the
Committee. In most years, the multiplier is intended to reflect the  Committee's
subjective  assessment of  the Management Committee's  performance as  a team in
areas that  may not  be fully  reflected  in current  EPS results.  These  areas
include  the strategic positioning of the  Company, the quality of the Company's
products, social and environmental responsibility initiatives, and the efficient
use of capital. Usually the multiplier can increase or decrease the basic  award
by  up  to  20%.  The  Committee may,  in  special  circumstances,  recognize an
exceptional individual contribution.  All of the  named executive officers  were
Management Committee members during 1995 except for Mr. Jain, who is included in
the group discussed immediately below.
 
     For  Mr. Jain and other executive officers having direct responsibility for
the profitability of  a business unit,  the primary performance  measure is  the
operating income for their assigned business units. Operating income targets for
each  business unit are consistent with  and contribute to the Company's overall
EPS target. Awards for this group are adjusted by two multipliers, each of which
can
 
                                       17
 
<PAGE>
<PAGE>
increase or decrease  the basic  award by  20%. One  is based  on the  Company's
overall  EPS performance and the other  is based on personal performance factors
which may not be reflected in  financial results. For executive officers  having
staff  responsibilities, the basic performance measure  is EPS. Basic awards can
be increased or decreased up to 30% to reflect personal performance factors  and
contributions.
 
     For 1995 OAIP bonus awards, the EPS target was adjusted by the Committee to
reflect the fact that certain items did not pertain to the operating performance
of  the Company  in that  year. On  this basis,  EPS performance  fell below the
target level  of performance  (which  would generate  target basic  awards).  In
addition,  while  operating income  for  certain of  the  business units  of the
Company exceeded  operating  income  targets, other  business  units'  operating
income was insufficient to trigger payment of any OAIP awards. As a result, only
three officers of the Company received awards under the OAIP for 1995.
 
STOCK OPTION PLANS
 
     The  SOPs are designed to reward executive officers and other key employees
directly for appreciation  in the long-term  price of the  Company's stock.  The
plan  directly  links the  compensation of  executive officers  to gains  by the
shareholders and  encourages  executive officers  to  adopt a  strong  ownership
orientation in their work. The SOP also places what can be a significant element
of  compensation  at risk  because the  options  have no  value unless  there is
appreciation over time in the value of Company stock.
 
     In 1992 and 1995, respectively, shareholders approved the 1992 Stock Option
Plan for Employees of Witco Corporation and its Subsidiaries and the 1995  Stock
Option   Plan  for   Employees  of   Witco  Corporation   and  its  Subsidiaries
(collectively, the  'SOPs'). The  1992 Plan  replaced all  earlier stock  option
plans  in effect and the  1995 Plan supplemented the  number of shares available
for issuance under the 1992  Plan. The SOPs enable  the Committee to grant  both
incentive  stock  options  (as  defined  under  Section  422  of  the  Code) and
non-qualified stock options. Other than  the proposed Long Term Incentive  Plan,
which  shareholders are being  asked to approve at  the 1996 Annual Shareholders
Meeting, stock options  are the  only form of  long-term incentive  compensation
currently  used by the Company. However, the Committee periodically assesses the
relative merits of  alternative approaches  to long-term incentives  and may  at
some  future time introduce  other long-term incentives  to either supplement or
replace stock options.
 
     With the understanding that the value (if any) of stock options is based on
future performance, the  Committee bases  annual stock option  grants on  median
levels  of expected value for long-term  incentive grants among Comparison Group
companies and other comparable  corporate employers. The Committee  periodically
reviews the practices, grant levels, and grant values of the Comparison Group to
ensure the plan continues to meet the Company's objectives. Although options are
intended to reward future performance more than past or current performance, the
Committee  reserves the right to adjust annual grants in light of unusually poor
or exceptional corporate or individual performance.
 
COMPENSATION OF THE CHIEF EXECUTIVE OFFICER
 
     In determining the appropriate level of total compensation for Mr.  Toller,
the  Company's  Chief Executive  Officer,  the Committee  reviewed  the internal
compensation levels  of the  Company, total  compensation packages  provided  to
other  chief executive officers in the  Comparison Group and the Company's short
and long-term financial and strategic performance.
 
     In determining  Mr.  Toller's 1995  base  salary and  merit  increase,  the
Committee  took into  account the  Company's continued  expansion of  its global
manufacturing and marketing presence, and increases
 
                                       18
 
<PAGE>
<PAGE>
in the Company's total  level of sales  and return on  equity. In addition,  the
Committee  considered Mr. Toller's outstanding individual performance, including
his contributions to the continuing success  and increased value of the  Company
and  his leadership.  Based on  its consideration of  all of  these factors, the
Committee awarded  Mr. Toller  a base  salary of  $650,000, reflecting  a  merit
increase of 10.17%.
 
     The  Committee did not approve any OAIP award to Mr. Toller for performance
in 1995  as the  Company's EPS  performance fell  below the  threshold level  of
performance under the terms of the plan.
 
     In addition, on June 1, 1995 the Committee approved a stock option grant of
154,000  shares to  Mr. Toller  pursuant to the  provisions of  the Stock Option
Plans. In determining the total amount of  options to be granted to Mr.  Toller,
the  Committee assessed grant values provided  to other chief executive officers
in the Comparison Group, the success  of the Company in achieving its  financial
and  strategic performance goals  and the individual  performance of Mr. Toller.
The Committee believes that this award will further serve to place Mr.  Toller's
compensation  at risk while providing the potential for significant gain only if
the  Company's  shareholders  also  participate  in  an  appreciation  in  their
investment.
 
SUMMARY
 
     The Committee believes that the executive compensation program continues to
attract  and  retain  the  executive resources  needed  to  maximize shareholder
returns. The emphasis on compensation  incentives, which address both  long-term
and  annual performance as well as both financial and stock performance, ensures
that the program functions in the best interests of the Company's shareholders.

                                   PROPOSAL 2
             PROPOSAL TO APPROVE ADOPTION OF THE WITCO CORPORATION
                            LONG TERM INCENTIVE PLAN
 
     At a  meeting  held  on  March  5, 1996,  the  Board  adopted,  subject  to
shareholder  approval,  the  Witco  Corporation Long  Term  Incentive  Plan (the
'LTIP'). The LTIP awards participants in  Common Stock for their achievement  of
one  or more objective performance goals over the three-year performance period.
By making awards in Common Stock, the LTIP encourages LTIP participants to adopt
a strong ownership orientation  in their work  and makes a  part of their  total
compensation  dependent on objective business  and performance based criteria. A
copy of the LTIP is  annexed to the Proxy Statement  as Exhibit A and should  be
read in its entirety. The following is a brief summary of significant provisions
of the LTIP.
 
ADMINISTRATION
 
     The  LTIP  will be  administered by  a  committee of  the Board  (the 'LTIP
Committee') comprised solely of two or  more outside directors, all of whom  are
'disinterested  persons' (within  the meaning of  Rule 16b-3  promulgated by the
Securities and Exchange Commission  pursuant to the  Securities Exchange Act  of
1934). Members of the LTIP Committee are not eligible to receive awards.
 
SHARES AVAILABLE
 
     The number of shares of Common Stock available for awards under the LTIP is
600,000  shares, reduced by the aggregate amount of shares which are issued upon
award or that become subject to an outstanding award. To the extent that  shares
of  Common Stock related to outstanding awards are not issued either because the
targets for awarding such shares  have not been met  or because such awards  are
(i)  forfeited, (ii)  terminated or (iii)  delivered or withheld  to satisfy tax
withholding obligations, such  shares shall again  immediately become  available
for awards.
 
PARTICIPATION AND ELIGIBILITY
 
     Not   later  than  90  days  after  the  commencement  of  each  three-year
performance period, the LTIP Committee  will determine in writing the  corporate
officers  that will participate in the LTIP  for the performance period, and for
each  participant  (i)  the   applicable  performance  measurement(s)  for   the
performance period (based on one or more of the performance measurements defined
in  Appendix A of the  LTIP (including, for example,  return on equity, earnings
per share, return on  investment and shareholder  value)) and the  corresponding
performance  target(s),  (ii) a  Target Award  (corresponding  to the  number of
shares that the participant will  receive if, as of  the end of the  performance
period, the Company's actual performance equals the targeted performance levels)
and  (iii) an Award Range (the range of the percentage of the Target Award to be
obtained upon the attainment of various percentages of the targeted  performance
measurement(s)).  The performance measurement  and the corresponding performance
target applicable to each LTIP participant for the first performance period will
be based  on  a  targeted  Return  on Equity  (as  defined)  for  the  1996-1998
performance  period. The LTIP  Committee may cause an  individual who becomes an
eligible employee after a performance period has commenced (but within the first
year of such performance period) to  become a participant in the LTIP,  provided
that  the LTIP Committee establishes  the performance measurement(s) and related
performance target(s), a Target Award and an Award Range which will apply to the
participant for the performance period.
 
                                       21

<PAGE>
AWARDS
 
     As  soon  as  practicable  following  the  last  day  of  each   three-year
performance  period, but in any event no later than 90 days following such date,
the Company will determine for the  period whether the performance target(s)  in
respect  of  each participant's  performance  measurement(s) has  been achieved.
Subject to certain exceptions, each participant's award for a performance period
shall be a  percentage of the  participant's Target Award  corresponding to  the
level  or percentage of  the performance target(s)  achieved; provided, however,
that the participant's award may not exceed the Maximum Award (generally, 50,000
shares  of  Common  Stock);  and  provided,  further,  the  LTIP  Committee  has
discretion  to  reduce  any  participant's  award.  If  a  participant  did  not
participate in the  LTIP for  the entire performance  period, the  participant's
award  will be determined  for the entire  performance period but  then shall be
pro-rated based on the number of full and partial months within the  performance
period that the participant participated in the LTIP.
 
     Participants  will receive their  awards no later than  30 days after their
awards are determined;  provided, however,  that no awards  will be  distributed
prior  to  the  time that  the  LTIP  Committee certifies  in  writing  that the
performance target(s)  applicable to  each such  award has  been satisfied.  The
shares  of Common  Stock awarded to  each participant will  consist of one-third
unrestricted shares  and two-thirds  restricted shares.  Unless a  participant's
individual  grant letter provides otherwise, participants will receive dividends
and will have voting rights on their restricted shares.
 
     Restricted shares  generally  may not  be  transferred. However,  unless  a
participant's  individual grant letter provides otherwise, restricted shares may
be transferred for certain limited purposes (for example, to an estate or  trust
upon  a participant's  death or to  a participant's immediate  family for estate
planning purposes) and, in any event, only if the transferee agrees to be  bound
by  the terms of the LTIP. With certain exceptions, the restrictions on one-half
of the restricted shares will  lapse on the January  1st following the date  the
shares  are awarded; restrictions  on the remainder will  lapse on the following
January 1st.
 
EFFECT OF CHANGES; MID-PERFORMANCE PERIOD
 
     Except as set forth below, no participant will be entitled to an award with
respect to any performance period unless he or she is employed by the Company on
the last  day of  such  performance period.  In  addition, except  as  otherwise
provided  below, upon a  participant's termination of  employment, a participant
will forfeit all shares  of restricted Common Stock  for which the  restrictions
have not yet lapsed.
 
     In  the  event  of  the death,  disability,  retirement  or  termination of
employment without  cause, restrictions  on any  restricted shares  held by  the
participant will lapse, and if such death, disability, retirement or termination
of  employment without cause occurs  in the middle of  a performance period, the
participant's award for the performance period  will be paid to the  participant
(or,  if applicable, the participant's estate)  pro-rated based on the number of
full and  partial months  within  the performance  period that  the  participant
participated in the LTIP.
 
     The  LTIP also contains  provisions addressing the  possibility that in the
middle of a performance period a  participant will be transferred to a  position
with   different   performance  criteria   (i.e.,   performance  measurement(s),
performance target(s), Target  Award and Award  Range). In the  event of such  a
transfer,  the performance criteria applicable to the new position will apply to
the participant for the remainder of the performance period (with the amount  of
the award determined pro-rata for each
 
                                       22
 
<PAGE>
<PAGE>
portion  of the performance period based  on the applicable criteria) unless (i)
the Committee determines  that the  participant shall  not be  eligible for  the
remainder of the performance period (in which case the participant's award shall
be  determined on a pro-rata  basis based on his  or her performance criteria in
effect prior to  the date of  transfer), or (ii)  attainment of the  performance
target(s) applicable to the new position is substantially certain (in which case
the participant's award for the performance period will be based entirely on the
criteria  applicable  to  his  or  her former  position).  If  a  participant is
transferred to  a new  position  for which  no  performance criteria  have  been
previously  established,  the participant  will continue  to  be covered  by the
criteria applicable  to  his or  her  former  position unless,  within  90  days
following  the date of  the transfer, the  Committee establishes new performance
criteria which  shall  apply  to  the  participant  for  the  remainder  of  the
performance period.
 
CHANGE IN CONTROL
 
     The  LTIP provides that, in the event of a Change in Control of the Company
(as defined in the LTIP),  all performance periods under  the LTIP will end  and
all  participants will receive a  cash amount equal to  150% of the Target Award
multiplied by (i) a fraction, the numerator of which will be the number of  full
and  partial months  in which  the participant  participated in  the performance
period and the denominator of which will be the total number of full and partial
months in the performance period, and (ii) the highest price per share of Common
Stock paid on or during the 60-day period immediately preceding the first public
disclosure of events that lead  to a Change in Control  or the actual Change  in
Control.  If there is a  Subsequent Change in Control  (as defined in the LTIP),
LTIP participants will receive an additional cash payment equal to an excess (if
any) of the amount they would have received had the Subsequent Change in Control
been the initial Change in Control. In determining the foregoing award, the LTIP
Committee has no discretion to reduce the award. In addition, in the event of  a
Change  in Control (i) the restriction on  the maximum number of shares that may
be awarded to any participant for any performance period will not apply and (ii)
all restrictions on restricted  shares awarded under  the LTIP will  immediately
lapse.
 
AMENDMENT/TERMINATION
 
     The  LTIP Committee  may at  any time  amend the  LTIP with  respect to any
performance period which has not yet  commenced; provided, however, that (i)  no
amendment for which shareholder approval would be required to satisfy either the
requirements  of Rule  16b-3 under  the Securities Exchange  Act of  1934 or the
requirements  necessary   for   amounts   payable   to   be   'performance-based
compensation'  (within  the  meaning  of  Code  Section  162(m)(4)(C))  shall be
effective until such shareholder approval has been obtained and (ii) the Maximum
Award may  be increased  only  if shareholder  approval  is obtained.  The  LTIP
Committee may at any time terminate or suspend the LTIP; provided, however, that
if  the LTIP  Committee terminates or  suspends the LTIP  prior to the  end of a
performance period, each participant will receive the greater of: (i) the  award
he  or  she would  have received  had  such termination  or suspension  not been
effected, and  (ii)  the award  he  or she  is  entitled to  receive  under  any
replacement  plan  covering  the  same time  period.  Subject  to  the foregoing
requirement, upon termination of the LTIP, all other rights of each  participant
with  respect to any  performance period that has  not ended on  or prior to the
date of termination shall become null and void.

CURRENT DETERMINATION OF AWARDS
 
     For the three year  performance period 1996-1999,  the LTIP Committee  has,
subject  to approval of  the LTIP by the  Company's shareholders, established an
aggregate award for 16 of the  Company's executive officers of 64,200 shares  of
Common  Stock, including  the following  target awards  to the  five most highly
compensated executive officers: Mr. Toller (18,500 shares), Mr. Mahoney  (11,500
shares),  Mr.  Fullwood (5,900  shares), Mr.  Katz (3,900  shares) and  Mr. Jain
(2,900 shares). The target  award for the 1996-1999  performance period will  be
earned  if the Company's Return  on Equity for the  period averages 12.5%. It is
not possible to state which employees will be granted awards under the LTIP  for
performance  periods  commencing  after  1996  because  these  matters  will  be
determined by the LTIP Committee in the  future in accordance with the plan.  In
addition,  it is not possible to state the amount of shares of Common Stock that
may be  earned at  the end  of the  1996-1999 performance  period or  thereafter
because  the amount  of shares  earned pursuant  to an  award in  respect of any
three-year performance period is based  on the Company's performance during  the
relevant  three-year  period.  For  information  concerning  previous  long-term
compensation awards  to the  Company's five  most highly  compensated  executive
officers in the form of options to acquire shares of Common Stock under the 1992
and  1995 Stock Option Plans,  see the information set  forth under the captions
'Executive Compensation -- Cash Compensation -- Summary Compensation Table'  and
' -- Stock Option Grants'.
 
U.S. FEDERAL TAX ISSUES AND OTHER INFORMATION
 
     A participant who receives restricted shares of Common Stock under the LTIP
will  not recognize taxable income at the time of receipt unless the participant
elects otherwise under Section  83(b) of the  Code. In the  absence of any  such
election,  such  participant  will recognize  ordinary  income at  the  time the
restrictions lapse equal to the excess of the fair market value of the shares at
that time over the amount, if any,  paid for such shares. The fair market  value
of  unrestricted  shares of  Common Stock  paid under  the LTIP  will constitute
ordinary income taxable to a  participant in the year  in which received by  the
participant. The participant's holding period for the shares received will begin
at the time taxable income is recognized under these rules, and the tax basis in
the  shares will be the amount of ordinary income so recognized plus the amount,
if any, paid for the shares. Moreover, any dividends received by the participant
on the restricted shares prior to  the date that the employee recognizes  income
as  described above will be taxable compensation income (rather than as dividend
income) when  received and  the  Company will  be  entitled to  a  corresponding
deduction,  except to the extent  the deduction limits of  Section 162(m) of the
Code and the regulations thereunder apply. Subject to Section 162(m) of the Code
and regulations  thereunder,  the  Company  generally  will  be  entitled  to  a
deduction equal to the amount of income recognized by a participant.
 
     Special  rules may  apply to  officers subject  to liability  under Section
16(b) of the Securities Exchange Act of 1934 that may prevent the recognition of
income by such individuals and the corresponding deduction by the Company before
the date six months following the grant of restricted stock (unless the employee
elects to be taxed upon such receipt).
 
     Pursuant to Code Section 162(m) and the regulations issued thereunder,  the
allowable deduction for compensation paid or accrued with respect to each of the
chief executive officer and the four other most highly compensated officers of a
publicly  held  corporation  at  the  end of  each  fiscal  year  is  limited to
$1,000,000 per year. However,  certain types of  compensation are excluded  from
this  deduction limit, including payments subject to the attainment of objective
performance measures  and  satisfaction  of  outside  director  and  shareholder
approval   requirements.   Awards  under   the   LTIP  are   expected   to  meet
 
                                       24
 
<PAGE>
<PAGE>
the performance-based compensation requirement  because the amounts are  awarded
upon  meeting  the performance  measures  based on  objective  business criteria
established by the LTIP  Committee for each  three-year performance period.  The
administration  by  the LTIP  Committee, as  limited by  provisions in  the LTIP
governing the  LTIP Committee's  discretion in  making awards  to  participants,
meets  the second  requirement. The submission  for shareholder  approval of the
LTIP (including the  performance measurements  continued in Appendix  A and  the
methodology  for calculating LTIP awards) is  intended to qualify LTIP awards as
performance based compensation so as to preserve the Company's tax deduction  if
and when any LTIP awards are made.
 
     Upon the occurrence of a Change in Control or Subsequent Change in Control,
all  or a portion  of a participant's  Target Award payments  and any restricted
shares whose restrictions lapse upon the  occurrence of a Change in Control  may
be  a parachute payment for purposes of  determining whether a 20% excise tax is
payable by the participant  as a result  of the receipt  of an excess  parachute
payment  pursuant to  Section 4999  of the  Code. If  the participant  is also a
participant in the Company's Supplemental  Executive Retirement Plan, he or  she
will  be entitled under such  plan to a tax gross-up  payment to offset any such
excise tax imposed on benefits payable under  that plan or under any other  plan
or  arrangement,  including  the LTIP.  Any  such parachute  payments  which are
determined to be excess  parachute payments will  generally be nondeductible  by
the Company.
 
     The  affirmative vote  of the  holders of a  majority of  the shares having
voting power  present  in person  or  represented by  proxy  at the  meeting  is
required to approve the adoption of the LTIP.
 
     THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS THAT SHAREHOLDERS VOTE FOR
THIS  PROPOSAL  TO  APPROVE THE  ADOPTION  OF  THE WITCO  CORPORATION  LONG TERM
INCENTIVE PLAN.
 
                                   PROPOSAL 3
                    PROPOSAL TO APPROVE THE AMENDMENT OF THE
                 1995 STOCK OPTION PLAN FOR EMPLOYEES OF WITCO
                        CORPORATION AND ITS SUBSIDIARIES
 
     At a  meeting  held  on  March  5, 1996,  the  Board  adopted,  subject  to
shareholder  approval, an amendment to the 1995 Stock Option Plan (i) increasing
the number of shares  of Company Common Stock  available for option awards  from
2,600,000  shares to 3,600,000 shares and  (ii) increasing the maximum number of
option shares of Company Common Stock that  may be granted to any person  during
the  term  of the  plan  from 1,300,000  shares  to 2,000,000  shares.  The plan
directly  links  the  compensation  of  executive  officers  to  gains  by   the
shareholders  and  encourages executive  officers  to adopt  a  strong ownership
orientation in their work. The 1995 Stock Option Plan also places what can be  a
significant  element of compensation  at risk because the  options have no value
unless there is appreciation over time in  the value of Company stock. The  1995
Stock  Option Plan was approved by the  shareholders at the 1995 Annual Meeting.
No other amendments to the 1995 Stock Option Plan are proposed. Set forth  below
are the material provisions of the 1995 Stock Option Plan.
 
ADMINISTRATION
 
     The  1995 Stock Option Plan  is administered by a  committee (the '1995 SOP
Committee') which  consists  of  not less  than  three  non-employee  Directors.
Members of the 1995 SOP Committee are not eligible to receive awards.
 
                                       25
 
<PAGE>
<PAGE>
PARTICIPATION AND ELIGIBILITY
 
     The  1995 SOP  Committee may  grant options to  the officers  and other key
employees of the Company and its Subsidiaries to purchase up to 3,600,000 shares
of the Company's Common Stock at a price which may not be less than fair  market
value  (as defined in  the plan) of the  Common Stock on the  date the option is
granted; provided, however, that no person may be granted options for more  than
2,000,000 shares during the term of the 1995 Stock Option Plan. The plan permits
the  1995 SOP Committee to  grant either incentive stock  options, as defined in
Section 422 of the  Code, or nonqualified  stock options which  do not meet  the
requirements  of incentive stock options, or both. As of March 1, 1996, the fair
market value of the Common  Stock was $32.25 per  share. Options under the  1995
Stock Option Plan may not be granted after March 1, 2005.
 
     The  1995 SOP Committee determines, subject to  the terms of the 1995 Stock
Option Plan, the individuals to whom options will be granted, the time at  which
options  will be granted, the number of  options granted to each individual, the
option price per share,  and all other matters  necessary for administration  of
the 1995 Stock Option Plan.
 
     No  option may be exercised after the expiration of ten years from the date
it is granted.  If the optionee  and the Company  agree to the  amendment of  an
incentive  stock  option  agreement  in  a  manner  which  grants  the  employee
additional benefits, the amendment is deemed to be a grant of a new option,  and
if  the requirements for  incentive stock option  treatment are not  met at that
time, the option will no longer qualify  as an incentive stock option. The  1995
Stock  Option  Plan also  contains provisions  concerning the  exercisability of
stock options upon  the optionee's retirement,  permanent and total  disability,
death  or other  termination of employment.  Unless otherwise  determined by the
1995 SOP Committee, an option may not be exercised until one year following  the
date  of grant,  at which time  20% of the  shares subject to  the option become
exercisable and  an  additional 20%  become  exercisable  on each  of  the  four
succeeding anniversaries as long as the optionee continues to be employed by the
Company.
 
     Payment  for shares of Common  Stock of the Company  upon exercise of stock
option may be made in  cash, or in such other  form of consideration, as  deemed
appropriate  by the 1995 SOP Committee (including cashless exercise procedures),
or shares of Common Stock, or a combination of cash and shares of Common Stock.
 
CHANGE OF CONTROL
 
     The 1995 Stock Option Plan provides that the options will be exercisable in
full for a period of  thirty days following the date  of a change in control  of
the Company (as defined in the plan), unless exempted by the 1995 SOP Committee,
or  commencing on the date of shareholder approval of an agreement providing for
a merger  in  which  the  Company  will  not  remain  independent.  All  options
outstanding  at the end  of the thirty-day  period are to  be surrendered to the
Company for cancellation in exchange for a cash settlement payment.
 
AMENDMENT/TERMINATION
 
     The 1995 Stock Option  Plan is subject to  amendment or termination by  the
Board  of Directors,  as deemed  in the  best interest  of the  Company, without
shareholder approval; provided,  however, that unless  shareholders shall  first
approve   thereof,   no   such   amendment   shall   be   effective   for  which
 
                                       26
 
<PAGE>
<PAGE>
shareholder approval is required  in order to satisfy  the requirements of  Rule
16b-3  of the  Securities Exchange  Act of  1934, the  Code, the  New York Stock
Exchange, or any applicable state law.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     Under current tax  law, there  are no  Federal income  tax consequences  to
either  the employee or the Company on  the grant of nonqualified stock options.
Upon exercise of  a nonqualified  stock option, the  excess of  the fair  market
value  of the shares subject  to the option over  the option price ('Spread') at
the date of exercise is taxable as  ordinary income to the optionee in the  year
it is exercised and, subject to the limitation described below, is deductible by
the  Company for Federal income tax purposes. The optionee's basis in the shares
will be equal to the fair market value  on the date of exercise and the  holding
period commences on such date.
 
     Special  rules may  apply to  officers subject  to liability  under Section
16(b) of the Securities Exchange Act of 1934 that may prevent the recognition of
income by such individuals and the corresponding deduction by the Company before
the date  six months  following  the grant  of  the nonqualified  stock  options
(unless the employee receives the shares before that date and elects to be taxed
upon such receipt).
 
     Incentive  stock  option  holders  incur  no  regular  Federal  income  tax
liability at the time of  grant or upon exercise  of such option. However,  upon
exercise,  the Spread  will be  included as  alternative minimum  taxable income
which may give rise to 'alternative minimum tax' liability. An optionee's  basis
in  the shares  received on exercise  of an  incentive stock option  will be the
option price of  such shares for  regular income tax  purposes. No deduction  is
allowable  to the Company for Federal income tax purposes in connection with the
grant or exercise of such option.
 
     If the holder  of shares acquired  through exercise of  an incentive  stock
option  sells such shares, within two years of  the date of grant of such option
or within one year from  the date of exercise  of such option (a  'Disqualifying
Disposition'),  the  optionee will  realize  income taxable  at  ordinary rates.
Ordinary income  is  reportable  during the  year  of  such sale  equal  to  the
difference  between the option price and the  fair market value of the shares at
the date the option is exercised,  but the amount includable as ordinary  income
shall  not exceed the  excess, if any, of  the proceeds of  sale over the option
price. In addition to ordinary income, a Disqualifying Disposition may result in
taxable income subject to capital gains treatment, if the sales proceeds  exceed
the  optionee's  basis in  the shares  (i.e.  the option  price plus  the amount
includable as ordinary income). Subject  to the limitation described below,  the
amount  of  the optionee's  taxable ordinary  income will  be deductible  by the
Company in the year of the Disqualifying Disposition.
 
     Shares delivered  to  pay  for  shares purchased  on  the  exercise  of  an
incentive  stock option or nonqualified stock option  will be valued at the fair
market value at the date of exercise. Unless the delivery of shares  constitutes
a  Disqualifying Disposition  of shares acquired  upon exercise  of an incentive
stock option, no taxable gain or loss on the surrendered shares will be realized
at that time. For Federal income tax purposes, the optionee receives a basis and
holding period in the same number of new shares equal to his original tax  basis
and  holding  period in  the old  shares exchanged.  The optionee  also receives
additional shares equal in value to the  aggregate Spread which have a zero  tax
basis  in the case of an incentive stock option or a tax basis equal to the fair
market value at the date of exercise in the case of a nonqualified stock  option
and a new holding period in either case.
 
                                       27
 
<PAGE>
<PAGE>
     At  the time of the  sale of those shares received  upon the exercise of an
option (other  than a  Disqualifying  Disposition of  shares received  upon  the
exercise  of  an incentive  stock  option), any  gain  or loss  is  long-term or
short-term capital gain or loss, depending upon the holding period. The  holding
period for long-term capital gain or loss treatment is more than one year.
 
     Pursuant  to  Code  Section 162(m),  the  Company's tax  deduction  for all
compensation paid to each  of certain specified officers  in any one year  after
1993 is limited to $1,000,000. The Company's deduction arising from an officer's
exercise  of a  stock option (or  a Disqualifying Disposition  of the underlying
stock acquired through the exercise of an incentive stock option) will be exempt
from this  limitation  if  certain outside  director  and  shareholder  approval
requirements  are met. It is anticipated that  such requirements will be met for
options granted under the 1995 Stock Option Plan.
 
     If the exercisability of an option is  accelerated as a result of a  Change
in  Control, all or a portion  of the value of the option  at that time may be a
parachute payment  for purposes  of  determining whether  a  20% excise  tax  is
payable  by the participant  as a result  of the receipt  of an excess parachute
payment pursuant to  Section 4999  of the  Code. If  the participant  is also  a
participant  in the Company's Supplemental Executive  Retirement Plan, he or she
will be entitled under such  plan to a tax gross-up  payment to offset any  such
excise  tax imposed on benefits payable under  that plan or under any other plan
or arrangement,  including  the  1995  Stock Option  Plan.  Any  such  parachute
payments  which are determined to be excess parachute payments will generally be
nondeductible by the Company.
 
CURRENT DETERMINATION OF AWARDS
 
     It is not possible  to state which employees  will be granted awards  under
the  1995 Stock Option Plan in  the future or the amount  of options that may be
awarded to a  participant or  the exercise price  of any  options because  these
matters will be determined by the 1995 SOP Committee in the future in accordance
with  the plan. For  information concerning previous stock  option awards to the
Company's five most  highly compensated  executive officers under  the 1992  and
1995  Stock  Option Plans,  see  the information  set  forth under  the captions
'Executive Compensation -- Cash Compensation -- Summary Compensation Table'  and
' -- Stock Option Grants'.
 
     The  affirmative vote  of the  holders of a  majority of  the shares having
voting power  present  in person  or  represented by  proxy  at the  meeting  is
required to approve the amendment of the 1995 Stock Option Plan.

                            OF INDEPENDENT AUDITORS
 
     The Board of Directors has appointed  Ernst & Young LLP as the  independent
auditors  to examine the accounts of the Company for the 1996 fiscal year. Ernst
& Young LLP has been serving the Company in this capacity for many years. In the
event that ratification  of this selection  of auditors is  not approved by  the
affirmative  vote  of a  majority  of the  shares  voting on  the  proposal, the
selection  of  independent  auditors  will  be  reconsidered  by  the  Board  of
Directors.

APPOINTMENT OF ERNST & YOUNG LLP AS THE COMPANY'S INDEPENDENT AUDITORS.
 
                                   PROPOSAL 5
                SHAREHOLDER PROPOSAL REQUESTING DIVERSITY ON THE
                      WITCO CORPORATION BOARD OF DIRECTORS
 
     The General Board of  Pension and Health Benefits  of the United  Methodist
Church,  1201 Davis Street, Evanston, Illinois,  the beneficial owner of 347,000
shares of Common Stock  of the Company has  submitted the following  shareholder
proposal for consideration at the 1996 Annual Meeting.
 
          WHEREAS,  we  believe  the  employee and  board  composition  of major
     corporations should reflect the people in the workforce and marketplace  of
     the  21st  Century, if  our  company is  going  to remain  competitive. Our
     employees, customers and stockholders are made up of a greater diversity of
     backgrounds than ever  before. The Department  of Labor's 1995  bi-partisan
     Glass  Ceiling Commission report 'Good for Business: Making Full Use of the
     Nation's  Human  Capital'  confirms  diversity  and  inclusiveness  in  the
     workplace  has a positive impact on the bottom line. A Covenant Fund Report
     of Standard and Poor 500  companies revealed '. .  . firms that succeed  in
     shattering their own glass ceiling racked up stock market records that were
     nearly 2 1/2 times better than otherwise comparable companies'.
 
          The  Equal  Employment Opportunity  Commission  reports 97%  of senior
     ranks of corporations are occupied by  white males. We believe our  company
     needs  to open up top  management and the board  to qualified people of all
     races and to women.
 
          The Office of Federal Contract Compliance mandates that companies must
     not discriminate  on the  basis  of race,  sex, color,  religion,  national
     origin, disability, or veterans status. Women and minorities comprise fifty
     percent  of America's workforce,  and the U.S.  Department of Labor reports
     their advancement is  oftentimes hindered by  artificial barriers --  glass
     ceilings.  Our company must  make a strong and  continued commitment to use
     its available tools and resources to remove glass ceiling barriers, because
     it is our responsibility under the law, and the right thing to do.
 
          In  1994,  the  Investor   Responsibility  Research  Center   reported
     inclusiveness  at senior management and board levels was only 9% within the
     Fortune 500  companies, in  a comparable  workforce of  57% diversity.  The
     Glass Ceiling Commission reported that companies are selecting only half of
     the  available talent in our workforce. If our company is to be competitive
     in the  21st Century,  we must  recognize the  truth that  we exist  in  an
     increasingly  diverse  global  market, and  must  look to  select  the most
     qualified people, regardless  of race,  gender or  physical challenges.  We
     urge  our corporation  to enlarge its  search for the  best qualified board
     members by casting a wider net.
 
                                       29

     THEREFORE, BE IT RESOLVED that the shareholders request:
 
             1. The nominating  committee  of  the  Board,  in  its  search  for
                suitable  board candidates, make a  greater effort to search for
                qualified women and  minority candidates for  nomination to  the
                Board of Directors;
 
             2. A  report  on  our company's  efforts  to  encourage diversified
                representation on our Board of Directors;
 
             3. Report on  our company's  use of  minority and  women  executive
                search firms;
 
             4. Issue  a statement  making a  public commitment  to a  policy of
                inclusiveness  on  our  Board  of  Directors,  with  the   Chief
                Executive  Officer's policy program outlining  steps to be taken
                and an anticipated time line.
 
     The affirmative  vote of  a  majority of  the  shares having  voting  power
present  in person or represented by proxy at the meeting is required to approve
the adoption of the foregoing resolution.
 
     THE BOARD OF DIRECTORS RECOMMENDS  THAT THE SHAREHOLDERS VOTE AGAINST  THIS
PROPOSAL.
 
     The  Company  is committed  to providing  equal opportunity  to all  of its
employees and a work place free of discrimination. The Company abides by federal
and state  regulations  regarding  equal employment  opportunity  and  does  not
discriminate on the basis of race, color, religion, national origin, disability,
veteran status, age or sex.
 
     The Company's Board of Directors has a long-standing commitment to seek the
best  qualified persons  for membership  on the  Board, without  regard to their
gender  or  race.  The  Board's  objective  is  to  identify  candidates   whose
experience,  background,  abilities and  talents complement  those of  the other
members of the Board. The Board believes that requiring it to establish a policy
focused on a subset (women and minority candidates) of the universe of potential
candidates could be inconsistent with the Board's obligation to recruit the best
qualified candidates,  if such  candidates  turn out  to  be neither  women  nor
members  of a minority  group. In the  Board's view, the  principal criteria for
Board membership is a  candidate's ability to contribute  to the enhancement  of
shareholder  value, not a candidate's gender  or minority status. The Board does
not believe that gender or minority status alone is indicative of a  candidate's
qualifications. The Board has concluded, therefore, that the requirements of the
shareholder  proposal  are not  in  the best  interests  of the  Company  or its
shareholders. Rather, the Board believes that  the interests of the Company  and
its  shareholders are best  served by allowing the  Board maximum flexibility to
seek highly qualified directors with complementary skills and backgrounds.
 
                             SHAREHOLDER PROPOSALS
 
     If any  shareholder  intends to  present  a  proposal to  the  Company  for
inclusion  in its proxy statement relating to the annual meeting of shareholders
to be  held in  April 1997,  or wishes  to recommend  nominees to  the Board  of
Directors,  such proposal,  in writing and  addressed to the  Secretary, must be
received by the Company no later than November 26, 1996. A shareholder may bring
other business  before  an annual  meeting  by  giving written  notice  of  such
proposed  business, either by personal delivery or by United States mail, either
certified or  registered, return  receipt  requested, to  the Secretary  of  the
Company  at least ninety days  prior to the anniversary  date of the last annual
meeting held or not later than ten days after notice of public disclosure of the
date of the annual meeting is given  or made to shareholders, whichever date  is
earlier.    Such   notice    shall   set    forth   as    to   each    item   of
 
                                       30

description of such item of  business and the reasons  for conducting it at  the
meeting  and, in  the event that  such item  of business includes  a proposal to

material  interest of  the shareholder in  such item of  business. Only business
which has been  properly brought  before an  annual meeting  of shareholders  in
accordance with the by-laws shall be conducted at such meeting, and the Chairman
of  such meeting  may refuse to  permit any  business to be  brought before such
meeting which has  not been properly  brought before it  in accordance with  the
by-laws.
 
                      By order of the Board of Directors,

     vote  of  the  entire  membership  of  the  Organization  and  Compensation
     Committee  determining that  the Participant  has engaged  in conduct which
     constitutes Cause, which  resolution represents the  good faith opinion  of
     the  members  of  the  Organization  and  Compensation  Committee  that the

     hypothecation, or other disposition.
 
SECTION 4. ADMINISTRATION OF THE PLAN
 
     The  Plan  shall be  administered by  the Committee  which shall  have full
authority to administer the Plan, including the authority and the discretion  to
interpret  and construe  any provision  of the Plan  (except to  the extent that
discretion is  expressly limited  by this  Plan)  and to  adopt such  rules  and
regulations  for administering the  Plan as it may  deem necessary. Decisions of
the Committee  shall be  final and  binding on  all parties.  No member  of  the
Committee  shall  be liable  to  any Participant  for  any action,  omission, or
determination relating to the Plan. Whether an authorized leave of absence shall
constitute termination of employment shall be determined by the Committee in its
absolute discretion.
 
SECTION 5. SHARES AVAILABLE
 
     The number of shares of Common  Stock available for Awards under this  Plan
shall  be 600,000 shares,  reduced by the  aggregate amount of  shares which are
issued upon Award or that become subject to an outstanding Award. To the  extent
that  shares of Common Stock related to outstanding Awards are not issued either
because Targets have not been met or because such Awards are (i) forfeited, (ii)
terminated, or (iii) delivered or  withheld to satisfy withholding  obligations,
such shares shall again immediately become available for Awards.
 
SECTION 6. EFFECTIVE DATE
 
     This Plan shall be effective on January 1, 1996, subject to the approval of
the  Plan prior to January 1, 1997 by the holders of a majority of the shares of
the Company actually voting at a regular or special meeting of the  shareholders
of  the  Company. The  last  Performance Period  under  this Plan  shall  be the
Performance Period commencing on January 1, 2000, unless no later than the fifth
annual shareholders' meeting held after  January 1, 1997, the shareholders  have
again  approved  this Plan.  The  Committee may  take  the actions  described in
Section 7 hereof prior to the date of shareholder approval of the Plan, provided
such actions are taken subject to such shareholder approval.
 
SECTION 7. PARTICIPATION
 
     (a) Generally. Not later  than ninety (90) days  after the commencement  of
each  Performance  Period,  the  Committee  shall  determine  (i)  the  Eligible
Employees who shall participate in the Plan for
 
                                      A-3
 
<PAGE>
<PAGE>
such Performance Period, and (ii) for each Participant or group of Participants,
the Performance Measurements, the Target, the Target Award, and the Award Range.
 
     (b) Mid-Year Participants. An individual  who becomes an Eligible  Employee
after  a Performance  Period has  commenced but  within the  first year  of such
Performance Period may become a Participant  for such Performance Period if,  no
later  than ninety (90) days after such individual becomes an Eligible Employee,
the  Committee  (i)  designates  such  individual  as  a  Participant  for  such
Performance  Period, (ii) establishes the Performance Measurements and Target to
be met  for such  Performance Period,  and (iii)  establishes the  Participant's
Target Award and Award Range.
 
     (c)  Attainment of Target Must Not  Be Substantially Certain. The Committee
may not establish a Target for any  Performance Period, if attainment of any  of
the Performance Measurements upon which the Target is based is, at the time such
Target  is established for a Participant or group of Participants, substantially
certain.
 
     (d) Grant Letter. The Committee shall  cause the Company to communicate  to
each  Participant,  in writing,  the Maximum  Award  and the  applicable Target,
Target Award, and Award Range.
 
SECTION 8. DETERMINATION OF AWARD
 
     (a)  Measurement  of  Performance  Measurements.  As  soon  as  practicable
following  the Determination Date,  but in any  event no later  than ninety (90)
days following such date, the Company shall measure the Performance Measurements
applicable to the Participants' Target for such Performance Period.
 
     (b) Determination of Award. Except as  otherwise provided in Section 10  or
Section  11, each Participant's Award shall be a percentage of the Participant's
Target Award corresponding  to the  percentage of  the Target  achieved for  the
Performance  Period. The Award shall be determined by interpolating a percentage
based on the  Target achieved  for such Performance  Period; provided,  however,
that  the Participant's  Award may not  exceed the Maximum  Award; and provided,
further, the Committee shall have discretion to reduce any Participant's  Award.
Awards  shall  be determined  as soon  as  practicable following  the applicable
Performance Measurements are measured.
 
     (c) Receipt of  Awards. Participants  shall receive their  Awards no  later
than thirty (30) days after their Awards are determined; provided, however, that
no  Awards shall be provided  prior to the time  that the Committee certifies in
writing that the  Performance Measurements  applicable to each  such Award  have
been satisfied.
 
SECTION 9. RESTRICTED SHARES
 
     (a)  Which Shares Restricted.  Except as otherwise  provided in Sections 10
and 11, one-third of each Award shall be made in shares of Common Stock and  the
remaining  two-thirds of each Award shall be made in Restricted Shares which are
subject to  the  restrictions  described  in this  Section  9.  Restrictions  on
one-half of the remaining Award (which will be the portion awarded as Restricted
Shares)  shall  lapse  on  the  first  anniversary  of  the  day  following  the
Determination Date  on  which  the  shares were  awarded;  restrictions  on  the
remainder shall lapse on the second anniversary thereof.
 
     (b)  Transfer Restrictions. Restricted Shares may not be Transferred unless
the Transfer complies with the provisions of this Section 9.
 
                                      A-4

<PAGE>
     (c) Permitted Transfers.  Except as otherwise  provided in a  Participant's
Grant  Letter, the following Transfers of Restricted  Shares are deemed to be in
compliance with this Plan:
 
          (i) a Transfer made to the Company (or its assignee);
 
          (ii) a Transfer  upon the death  of the Participant  or any  Permitted
     Transferee   (as  hereinafter  defined)   to  their  respective  executors,
     administrators,  testamentary  trustees,  legatees  or  beneficiaries   (an
     'Estate');
 
          (iii)  a Transfer made  in compliance with  all applicable federal and
     state securities laws to a Participant's immediate family (which term shall
     mean the  Participant's spouse,  children (including  adopted children  and
     step  children),  their  direct lineal  descendants  and  the Participant's
     parents, brothers and sisters), or a trust, the beneficiaries of which,  or
     to  a corporation  or partnership, the  stockholders or  limited or general
     partners of which,  include only  the Participant's  and the  Participant's
     immediate  family (a  'Participant Entity'), or  a Transfer made  by such a
     Participant Entity back to  the Participant, or a  Transfer made to such  a
     trust,  corporation or partnership by  a person who has  become a holder of
     the shares of Common Stock in accordance with the provisions of this Plan;
 
provided, however, that a Transfer pursuant  to this Section shall not be  given
effect  on the books of the Company  unless and until the transferee shall agree
in writing, in form and substance  satisfactory to the Company, to become  bound
by all the terms of this Plan.
 
     (d)  No Other Restrictions. Except as  otherwise provided in this Section 9
or in a Participant's  Grant Letter, Participants shall  enjoy all of the  other
rights  of ownership associated  with the Restricted  Shares, including, without
limitation, the right to vote such shares and the right to receive dividends  on
these shares.
 
SECTION 10. EFFECT OF CHANGES; MID-PERFORMANCE PERIOD
 
     (a) Termination of Employment. Except as otherwise provided in this Section
10  or in Section 11, no Participant shall  be entitled to an Award with respect
to any Performance Period  unless he or  she is employed by  the Company on  the
last  day of such Performance Period.  In addition, except as otherwise provided
in this  Section  10 or  in  Section 11,  upon  a Participant's  termination  of
employment, a Participant shall forfeit all shares of Restricted Stock for which
the restrictions have not yet lapsed.
 
     (b)  Death, Disability,  Retirement, or  Termination of  Employment Without
Cause. In  the event  of the  death, Disability,  Retirement or  termination  of
employment without Cause of a Participant, restrictions on any Restricted Shares
held  by the Participant shall lapse, and, if such death, Disability, Retirement
or termination of employment without Cause occurs in the middle of a Performance
Period, any Award  for such  Performance Period  which the  Participant (or,  if
applicable, the Participant's estate) may become entitled to shall be determined
in  accordance with Section  10(d)(i). Awards provided  pursuant to this Section
10(b) shall not be subject to the provisions of Section 9.
 
     (c) Effect of  Job Change. If,  in the  middle of a  Performance Period,  a
Participant  is transferred to a position for which the Committee has previously
established a Target  and/or Award Range  which differs from  the Target  and/or
Award  Range applicable  to the Participant  immediately prior  to the transfer,
then:
 
          (i) Attainment of Previously Established  Target for New Position  Not
     Substantially  Certain. If, at the time  of the transfer, the attainment of
     the Target which the Committee established for
 
                                      A-5
 
<PAGE>
<PAGE>
     employees previously  holding the  position to  which the  Participant  was
     transferred  is not substantially certain, such  Target and the Award Range
     for such position  shall apply to  the Participant for  the portion of  the
     Performance   Period  beginning  on  the  date  of  the  transfer  and  the
     Participant's  Award  shall  be  determined  in  accordance  with   Section
     10(d)(ii)  below. Notwithstanding the  foregoing, at any  time prior to the
     90th day following the  date of such transfer  the Committee may  determine
     either  (A) that the Participant shall no longer be eligible to participate
     in  the  Plan  as  of  the  date  of  such  transfer  (in  which  case  the
     Participant's  Award  for such  Performance Period  shall be  determined in
     accordance with  Section 10(d)(i)  below), or  (B) that  the Target  and/or
     Award Range applicable to the Participant immediately prior to the transfer
     shall  continue to  apply (in which  case the Participant's  Award for such
     Performance Period shall be calculated as  if the Participant had not  been
     transferred).
 
          (ii)  Attainment  of  New  Position's  Previously  Established  Target
     Substantially Certain. If, at the time  of the transfer, the attainment  of
     the  Target  which  the  Committee established  for  employees  holding the
     position to which the Participant was transferred is substantially certain,
     the Target and/or  Award Range  applicable to  the Participant  immediately
     prior  to  the  transfer  shall  continue  to  apply  (in  which  case  the
     Participant's Award for such Performance  Period shall be calculated as  if
     the  Participant had  not been  transferred) unless  prior to  the 90th day
     following the  date of  such  transfer the  Committee determines  that  the
     Participant  shall no longer be  eligible to participate in  the Plan as of
     the date of such transfer (in  which case the Participant's Award for  such
     Performance   Period  shall  be  determined   in  accordance  with  Section
     10(d)(i)).
 
          (iii)  No  Targets  Previously   Established.  If  a  Participant   is
     transferred  to a position for  which a Target and  an Award Range have not
     previously been established, the Target  and Award Range applicable to  the
     Participant  immediately prior to the transfer  shall continue to apply (in
     which case the  Participant's Award  for such Performance  Period shall  be
     calculated  as if the Participant had not been transferred) unless prior to
     the 90th day following the date  of such transfer the Committee  determines
     (A)  that the Participant shall no longer be eligible to participate in the
     Plan as of the date of such transfer (in which case the Participant's Award
     for such Performance Period shall be determined in accordance with  Section
     10(d)(i)) or (B) establishes in writing the Target (the attainment of which
     must  not be substantially certain) and Award Range that shall apply to the
     Participant  on  and  after  the  date  of  transfer  (in  which  case  the
     Participant's   Award  shall  be  determined  in  accordance  with  Section
     10(d)(ii)).
 
     (d) Mid-Performance Period Changes: Determination of Awards.
 
          (i)  Participation  for  Less  Than  Full  Performance  Period.  If  a
     Participant  did not  participate in  the Plan  for the  entire Performance
     Period, the Participant's Award shall be the number of shares determined in
     accordance with Section 8(b) (or, if  the Participant has had a job  change
     resulting  in a mid-Performance Period change in Target and/or Award Range,
     the number  of  shares determined  in  accordance with  Section  10(d)(ii))
     multiplied  by a fraction,  the numerator of  which shall be  the number of
     full and partial months  in which the  Participant participated during  the
     applicable Performance Period and the denominator of which shall be 36.
 
          (ii)  Mid-Performance Period Changes. If a Participant's Target and/or
     Award  Range  changed  in   the  middle  of   a  Performance  Period,   the
     Participant's  Award  shall  be calculated  by  adding (A)  and  (B) below;
     provided, however, that the Participant's Award may not exceed the  Maximum
     Award; and provided, further, the Committee shall have discretion to reduce
     any Participant's Award.

     (e) Timing. Awards shall  be determined under this  Section 10, and  Common
Stock  awarded, at the same time that  Awards are determined and awarded for all

SECTION 11. CHANGE IN CONTROL
 
     (a) Determination of Awards. Notwithstanding any provision in this Plan  to
the contrary, in the event of a Change in Control, all Performance Periods under
the  Plan shall end, and  all Participants shall receive  a cash amount equal to
the product of  (i) 150%  of the  Target Award,  multiplied by  a fraction,  the
numerator  of which shall be the number of  full and partial months in which the
Participant participated in the Performance Period and the denominator of  which
shall  be the total number of full and partial months in the Performance Period,
and (ii) the highest of (A) the highest price per share of Common Stock paid  on
or  during  the  60-day period  immediately  preceding either  the  first public
disclosure of an event which could, and  which in fact does, result in a  Change
in  Control,  (B) the  highest price  per  share paid  during the  60-day period
immediately preceding a Change in Control, or (C) the price per share of  Common
Stock  paid  in a  tender offer  subsequent  to a  Change in  Control; provided,
however, that if, following a  Change in Control (but prior  to the time that  a
'person'  (as defined in Section 11(d)(ii)(A)) has acquired, by purchase, merger
or otherwise, 100% of the 'Voting Stock' (as defined in Section 11(d)(ii)(A)) of
the Company  (other than  an acquisition  by the  Company, an  Affiliate or  any
employee  benefit plan sponsored by  the Company or an  Affiliate, as such terms
are defined on the date of the Change in Control)), there is a subsequent  event
which  would itself be  a Change in  Control or a  subsequent tender offer (such
event, a 'Subsequent Change in Control'), each Participant shall be entitled  to
an additional payment (the 'Additional Payment') equal to the excess, if any, of
the  amount the Participant  would have received  under this Section  11 had the
Subsequent Change  in  Control been  the  Change  in Control,  over  the  amount
actually  paid to the Participant in respect  of the previous Change in Control.
For purposes of  this Section 11,  if the consideration  paid for the  Company's
Common  Stock includes amounts other  than cash, the 'price'  per share shall be
determined by valuing at fair market value the stock or other property  provided
as  consideration. In  determining the Award  under this  Section, the Committee
shall have no discretion to reduce this Award.
 
     (b) Restrictions on Common Stock Awarded. Notwithstanding any provision  in
this  Plan to the contrary, in the event of a Change in Control all restrictions
on Restricted Shares shall immediately lapse.
 
     (c) Payment of Award. No later than fifteen (15) days following a Change in
Control, the Company shall pay  the Award described in  this Section 11 to  each
individual who was a Participant on the
 
                                      A-7

<PAGE>
business  day immediately preceding the Change in Control, regardless of whether
such individual is an Eligible  Employee on or after  the Change in Control.  If
the  Company is required to make an Additional Payment under Section 11(a), such
Additional Payment shall be made no  later than fifteen (15) days following  the
date of the Subsequent Change in Control.
 
     (d)  Definitions. For  purposes of this  Section 11, the  terms below shall
have the following meanings:
 
          (i) 'Affiliate' shall mean (A) any corporation that is a member of the

     of trades  or businesses  under  common control  pursuant to  Code  Section
     414(b) that includes the Company.
 
          (ii) 'Change in Control' shall be deemed to have occurred if:
 
          (A)  any  'person',  as such  term  is  used in  Sections  3(a)(9) and
     13(d)(3) of  the Exchange  Act  other than  an  Affiliate or  any  employee
     benefit plan sponsored by the Company or an Affiliate becomes a 'beneficial
     owner',  as such term is used in  Rule 13d-3 promulgated under the Exchange
     Act, of 20% or more of the 'Voting Stock' (which means the capital stock of
     any class  or classes  of the  Company having  general voting  power  under
     ordinary  circumstances,  in the  absence  of contingencies,  to  elect the
     directors of such corporation) of the Company;
 
          (B) 33  1/3% of  the  Board consists  of  individuals other  than  the
     members  of  the  Board on  January  1, 1996  (the  'Incumbent Directors');
     provided, however, that any person  becoming a director subsequent to  such
     date  whose election or nomination for  election was approved by two-thirds
     (but in no event less  than two) of the directors  who at the time of  such
     election  or  nomination comprise  the Incumbent  Directors (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, which is or would be  subject
     to Rule 14a-11 of Regulation 14A promulgated under the Exchange Act) shall,
     for purposes of this Plan, be considered an Incumbent Director;

     distribution of all or substantially all of its assets;
 
          (D) the  Company combines  with another  company (whether  or not  the
     Company   is  the   surviving  corporation)  and,   immediately  after  the
     combination, the  shareholders  of the  Company  immediately prior  to  the
     combination   (other  than  shareholders  who,  immediately  prior  to  the
     combination, were  'affiliates' of  such  other company,  as such  term  is
     defined  in the  rules of  the Securities  and Exchange  Commission) do not
     beneficially own, directly or indirectly, more than 20% of the Voting Stock
     of the combined company  (or any company  owning 100% of  the stock of  the
     combined  company); or (E) any sale,  lease, exchange or other transfer (in
     one  transaction  or  a  series   of  related  transactions)  of  all,   or

restrictions  will lapse, partial shares equal to or in excess of .5000 shall be
rounded up and partial shares below .5000 shall be rounded down.

     (b) Withholding.  All awards  hereunder shall  be subject  to any  required
federal,  state,  local  and  other  applicable  withholdings  or  deductions as
determined by the Company.  The Committee may permit  a Participant to elect  to
pay  a portion or  all of such withholding  by (i) delivery  of shares of Common
Stock, or (ii) having shares  of Common Stock withheld  by the Company from  the
shares  otherwise to be received. The number  of shares so delivered or withheld
shall have an aggregate fair market  value sufficient to satisfy the  applicable
withholding  taxes. In the  case of a  Participant subject to  Section 16 of the
Exchange Act, the Company may require that the method of making such payment  be
in compliance with Section 16 and the rules and regulations thereunder.
 
     (c)  Not a  Contract of  Employment. Nothing  contained in  this Plan shall
confer upon any Participant any right with respect to the continuation of his or
her employment by  the Company or  interfere in any  way with the  right of  the
Company  at any time to terminate such employment or to increase or decrease the
base salary or other compensation of the Participant from the rate in effect  at
the commencement of a Performance Period.
 
     (d)  Certain Adjustments.  In the event  of a corporate  event that affects
Common Stock  (i.e., recapitalization,  stock  split, stock  combination,  stock
reclassification,  merger, or similar event), the Committee may make appropriate
adjustments to (i) the number  of shares of Common  Stock subject to this  Plan,
and  (b) the  number of  shares of  Common Stock  available for,  or covered by,
Awards; provided, however, that, except for adjustments made in connection  with
a  Change in  Control (as defined  in Section  11), no such  adjustment shall be
effected with respect  to any  Participant if  such adjustment  would cause  any
portion  of the Participant's Award  to constitute other than 'performance-based
compensation' within the meaning of Code Section 162(m)(4)(C).
 
     (e) Amendment/Termination. The Committee  may at any  time amend this  Plan
with  respect to any  Performance Period which has  not yet commenced; provided,
however, that no amendment for which  shareholder approval would be required  to
satisfy  either the requirements of Rule 16b-3 or the requirements necessary for
amounts payable  hereunder to  be 'performance-based  compensation', within  the
meaning  of Code Section 162(m)(4)(C), shall be effective until such shareholder
approval has been obtained. The Committee  may at any time terminate or  suspend
this Plan; provided, however, that, if the Committee terminates or suspends this
Plan  prior to the end  of a Performance Period,  each Participant shall receive
the greater of (i) the Award he or she would have received had such  termination
or  suspension not been effected, and (ii) the award the Participant is entitled
to receive under any replacement plan covering the same time period. Subject  to
the  foregoing requirement,  upon termination of  the Plan, all  other rights of
each Participant with respect to any Performance Period that has not ended on or
prior to the date of termination shall become null and void.
 
     (f) Funding.  This  Plan  shall  be unfunded.  Awards  hereunder  shall  be
furnished  using the  general assets  of the  Company and  Participants shall be
general unsecured creditors of the Company. No Participant shall have any right,
title, claim  or interest  in or  with respect  to any  specific assets  of  the
Company in connection with his or her participation in this Plan.
 
     (g)  Governing Law; Interpretation. This Plan  shall be governed by laws of
the State of Delaware, to the extent not preempted by federal law. This Plan  is
intended  to  be  administered in  accordance  with  Rule 16b-3  and  all rights
hereunder shall be  construed in accordance  with such provision.  This Plan  is
also  intended  to provide  Participants with  'performance-based compensation',
within the  meaning  of  Code  Section  162(m)(4)(C),  and  all  rights  of  the
Participants  hereunder  (except for  those rights  the Participants  may obtain
under Section 11 hereof) shall be construed in accordance with such provision.
 
     (h) Construction. For  purpose of  this Plan,  the word  'days' shall  mean
calendar days.

                            LONG TERM INCENTIVE PLAN
                            PERFORMANCE MEASUREMENTS
 
     1.  'Return on Equity' shall mean, as of any date, a percentage obtained by
dividing Net Earnings by Average Equity  and multiplying the result by 100.  For
this  purpose 'Average Equity' is defined as the number obtained by adding total
shareholders' equity  as  of  the  Determination  Date  and  the  December  31st
preceding  the  Determination  Date  (as  reported  on  the  Company's financial
statements) and dividing by 2.
 
     2. 'Earnings Per Share' shall mean, as of the end of any year, Net Earnings

determined by dividing Net Earnings less dividends paid during the year by total
shareholders' equity.
 
     4.  'Shareholder Value' shall mean,  as of the end  of any year, the number
determined by applying the following formula:
 
             Multiply Adjusted Operating Earnings  by (1.00 minus the  Effective
        Tax Rate).
 
             Subtract  the result by the sum  of the incremental amount of Fixed
        Capital Investment and Working Capital Investment during the year.
 
             Divide the result by the Weighted Average Cost of Capital.
 
             For this purpose,
 
             'Adjusted Operating Earnings'  shall mean  the Company's  operating
        income   excluding   interest   income,   interest   expense,   and  all

             'Weighted Average Cost of Capital'  shall mean the rate  determined
        by  adding the Weighted Average Cost  of Equity and the Weighted Average
        Cost of  Debt. 'Weighted  Average Cost  of Equity'  shall be  determined
        using  the following formula: (Rf  + (Rm -Rf)) x (1.00   - Total Debt to
        Capital Ratio).  'Weighted Average  Cost of  Debt' shall  be  determined
        using the following formula: Total Debt to Capital Ratio x Total Cost of
        Debt. For purpose of these calculations:
 
           Rf (risk free rate) = the rate on 30 Year Treasury bills
 
           Rm (market risk premium) = 6%
 
          'b' (risk premium) = the 'b' for the Company as reported by Bloomberg.
 
           'Total  Cost  of Debt'  = weighted  average  cost of  long-term and
        short-term debt.
 
           'Working  Capital  Investment'  shall  mean  current  assets  minus
        current  liabilities (other  than short-term  debt), as  reported on the
        Company's financial statements.

     delinquent  under  the  terms of  a  contract  or purchase  order)  for the
