     The  proxy will be voted in accordance  with the instructions of the person
executing the same. In the absence of instructions to the contrary, proxies will
be voted FOR the election  of the five nominees  for director named herein;  FOR

of Ernst & Young LLP as the Company's independent auditors for 1995.
 
     The  proxy is revocable  by a shareholder  at any time  before the exercise

number of shares present  and voting for the  purposes of determining whether  a

                                   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. The number of directors to be elected at the  1995
Annual Meeting is fixed at five. The directors who are nominated for election by
the  shareholders at the  1995 Annual Meeting are  Messrs. Ashe, Burns, Mahoney,
Polite and Wishnick.
 
     All of the  nominees were elected  by the shareholders  at the 1992  Annual
Meeting  for a three year term. In order  to comply with the requirements of the
Company's By-laws and Restated Certificate  of Incorporation that the number  of
directors in each class be as nearly equal as possible, Mr. Ashe will be elected
to  hold office until the Annual Meeting of Shareholders to be held in 1996, and
Messrs. Burns, Mahoney, Polite and Wishnick will be elected to hold office until
the Annual Meeting of Shareholders to be held in 1998, or until their successors
are elected and  qualify. Under  the Board's  current retirement  policy, it  is
anticipated  that Mr. Polite will serve two  years of his three year term. 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 February 28, 1995, and other positions held during the past five years are
set forth below.

     The  information provided in the above chart  as to each director and named
executive officer, individually, and all  directors and executive officers as  a
group  is  based on  information received  from  such individuals.  However, the
listing of such shares is not  necessarily an admission of beneficial  ownership
by  the  person.  Unless  otherwise  indicated  in  the  footnotes  below,  such
individuals held, together with certain members of their family, sole voting and
investment power over the shares.
 
 (a) Represents options exercisable within  60 days granted  under the 1989  and
     1992  Stock Option  Plans to such  persons. The options  are exercisable at
     prices ranging from $13.00  to $31.75. The closing  price for Witco  Common
     Stock  on the New York Stock Exchange  on February 28, 1995 was $28.625 per

     Wishnick is a director and president and, as president, has sole voting and
     investment  power  over  the  shares.  Mr.  Wishnick  disclaims  beneficial
     ownership of the Witco shares held by this foundation.
 
COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT
 
     Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
directors and  officers, and  persons who  own more  than 10%  of the  Company's
Common Stock, to file reports of ownership
 
                                       7
 
<PAGE>
and  changes  in  ownership of  any  class  of the  Company's  registered equity
securities with the Securities  and Exchange Commission and  the New York  Stock
Exchange.  The  Company  believes  that during  1994  all  Section  16(a) filing
requirements applicable to its directors and officers were complied with, except
that William E. Mahoney,  Vice Chairman, Messrs.  Brightwell and Golubock,  Vice
Presidents, and Messrs. Cohen, Jury and Uhoda, each of whom is retired, but held
the  position of Vice President during 1994, inadvertently failed to file a Form
4 in connection with a reallocation of investments under the Company's  Employee
Retirement Savings Plan when the Company changed the Administrator of that plan.
Those  delinquencies were corrected in the annual  Form 5 filed by each of those
officers.

     Set forth below is a table indicating those persons whom the management  of
the Company believes to be beneficial owners of more than 5% of any class of the

    The  1994  amounts shown  above in  the All  Other Compensation  column also
    include $150,487 for relocation expenses  paid or reimbursed by the  Company
    on  behalf of Mr. Toller,  $146,054 related to payments  for foreign cost of

    Katz's overseas assignment, and $113,529 for retirement benefits paid to Mr.
    Andreuzzi pursuant to the various retirement plans of the Company.
 
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 1995 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.
 
Stock Option Grants
 
     The following table  provides certain information  concerning the grant  of
options  during the year ended December 31, 1994 to the executive officers named
in the Summary Compensation Table.  In addition, hypothetical gains or  spreads,
calculated   based  on  assumed   rates  of  annually   compounded  stock  price
appreciation of 5% and 10%  over the term of the  option, have been included  in

(1) Each  option was granted on June 7, 1994 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.

    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.
 
(2) The  options were granted pursuant to the  1992 Stock Option Plan which does
    not provide for tandem or stand-alone stock appreciation rights.
 
(3) Payment for shares of Common Stock of  the Company upon exercise of a  stock
    option  may be  made in  cash, or  in such  other form  of consideration, as
    deemed  appropriate   by   the  Committee   (including   cashless   exercise
    procedures),  or shares of Common Stock, or a combination of cash and shares
    of Common Stock.
 
(4) Upon Mr.  Andreuzzi's retirement  on August  1, 1994,  these options  became
    immediately  exercisable  and  remain  exercisable  through  August  1, 1997
    pursuant to the terms of the 1992 Stock Option Plan. As such, the  potential
    realizable value calculation was adjusted accordingly.

                             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. Contributions to  the pension plan  in respect of any
person are  not  and  cannot  be  separately  or  individually  calculated.  The
aggregate  contribution to  the plan during  1994 was approximately  .41% of the
total remuneration of plan participants  covered by such plan. 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.
 
     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  bonuses   (averaged  over  three  years   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.
Toller $432,500,  Mr.  Mahoney  $337,400,  Mr.  Fullwood  $215,900,  Mr.  Seward
$149,300,  and  Mr. Katz  $148,100.  Mr. Andreuzzi  currently  receives $272,470
annually pursuant to his retirement effective August 1, 1994.
 
     In the event of death,  the Company will pay  a benefit to the  executive's
beneficiary.
 
     In  the event of the actual or  constructive termination of employment of a
participant within three  years after  a change in  control, as  defined in  the
SERP, he will be entitled to a lump-sum payable in cash equal to three times his
average total pay (averaged over five years) less $1.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     During  the  fiscal  year ended  December  31, 1994,  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 1995.
 
     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  1994  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 five 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 Plan, 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
 
                                       15
 
<PAGE>
expenditure of funds for cash incentives, the aggregate allocation of shares for
proposed stock  option  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 5 times during 1994.
 
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  two principal incentive programs  of the Company,  the
Officers'  Annual Incentive Program ('OAIP') and  the Stock Option Plan ('SOP'),
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.  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 1994 COMMITTEE ACTIONS
 
     As indicated above, the Company's executive compensation program has  three
principal  components: base salary,  annual cash incentives  under the OAIP, and
stock options under the SOP. The  Committee's decisions and actions during  1994
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  executive
officer's  sustained performance and cumulative contribution to the Company. The
current salary of each executive officer is compared to salary surveys and proxy
data  for   similar   positions  having   approximately   the  same   scope   of
responsibility. Each executive officer's individual performance is then reviewed
to  arrive at  a merit  increase determination.  These merit  increases are then
reviewed within the  context of  the total  merit increase  budget to  determine
reasonableness.  In 1994, merit  increases for individual  executive officers of
the Company ranged from  0% to 8.8%  of base salary  producing an average  merit
increase  of 5.6% 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 five  of the  six  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. This year, in the Committee's judgment, Mr.
Toller  merited  a  30%   multiplier  due  to  the   long-term  impact  of   his
accomplishments  which is not  necessarily reflected in current  EPS. He has led
the Company through successful acquisitions  and divestitures and established  a
global marketing and manufacturing presence. All of the named executive officers
were Management
 
                                       17
 
<PAGE>
Committee  members during 1994 except for Mr. Katz, who is included in the group
discussed  immediately  below.  Although  he  is  a  member  of  the  Management
Committee, Mr. Seward's primary performance measure is the operating results for
the Diversified Products Group.
 
     For  Messrs. Katz  and Seward  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 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 the  1994  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),  but exceeded  the threshold level  of performance  (which
would  generate minimum  basic awards  under the  plan). In  addition, operating
income for  certain of  the business  units of  the Company  exceeded  operating
income  targets, but other business units'  operating income was insufficient to
trigger minimum OAIP awards.
 
STOCK OPTION PLAN
 
     The SOP is 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 stakeholder
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 shareholders approved the 1992 Stock Option Plan for Employees (the
'Plan'),  which  replaced all  earlier stock  option plans  in effect.  The Plan
enables the Committee to  grant both incentive stock  options (as defined  under
Section  422 of the Code) and non-qualified stock options. 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
 
                                       18
 
<PAGE>
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 1994  base  salary and  merit  increase, the
Committee took  into account  the Company's  continued expansion  of its  global
manufacturing and marketing presence, and increases in the Company's total level
of sales and return on equity. In 1993, total sales increased by 23.9% from 1992
levels and return on equity before adjustments for non-recurring items was 13.2%
compared  with 10.8% in 1992. 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  social and
environmental leadership. An analysis of base salaries of other chief  executive
officers  in  the Comparison  Group  indicated his  pay  was slightly  below the
median. Based  on its  consideration  of all  of  these factors,  the  Committee
awarded  Mr. Toller a  base salary of  $590,000, reflecting a  merit increase of
8.3%.
 
     The Committee also approved  an OAIP award of  $430,100 for Mr. Toller  for
performance  in 1994.  This award  was based  on the  Company's EPS performance,
which fell below  the target  level of  performance but  exceeded the  threshold
level  of performance thus generating a minimum basic award less than the target
award, per the terms  of the plan.  This award was  adjusted by the  Committee's
assessment of the long-term impact of Mr. Toller's accomplishments, which is not
necessarily  reflected in current EPS.  The Committee considered the achievement
of various  non-financial  goals  of  the Company  referred  to  above  and  the
successful divestiture program.
 
     In addition, on June 7, 1994 the Committee approved a stock option grant of
125,000  shares  to  Mr. Toller  pursuant  to  the provisions  of  the  Plan. 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 1995 STOCK OPTION PLAN FOR EMPLOYEES OF
                     WITCO CORPORATION AND ITS SUBSIDIARIES
 
     As of January  31, 1995,  there were  539,660 options  available for  grant
under the 1992 Stock Option Plan. The Company's Stock Option Plan is 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 stakeholder orientation in their work.  The
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.
 
     As it  is  the general  practice  of the  Company  to grant  stock  options
annually,  the  Organization and  Compensation  Committee (the  'Committee') has
determined that the remaining  options available for  grant may be  insufficient
for  granting  future  options to  retain  and  attract officers  and  other key
employees. As such, the Committee believes it would be in the best interests  of
the Company to adopt a new stock option plan.
 
     Accordingly,  upon  the  recommendation  of  the  Committee,  the  Board of
Directors adopted the 1995 Stock Option Plan for Employees of Witco  Corporation
and  its Subsidiaries (the 'Plan') on March  2, 1995, subject to the approval of
the shareholders.  A copy  of the  Plan 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 Plan.
 
     The Committee may grant options to the officers and other key employees  of
the  Company and  its Subsidiaries  to purchase  up to  2,600,000 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  shall  be  granted options  for  more  than
1,300,000  shares during the  term of the  Plan. The Plan  permits the Committee
administering the Plan to  grant either incentive stock  options, as defined  in
Section  422 of the Internal  Revenue Code of 1986,  as amended (the 'Code'), or
nonqualified stock options which do not meet the requirements of incentive stock
options, or both. As of March 2, 1995, the fair market value of the Common Stock
was $28.875 per share. Options under the Plan may not be granted after March  1,
2005.
 
     The  Plan  will be  administered by  the Committee,  which will  consist of
non-employee  Directors  (not  less  than  three)  appointed  by  the  Board  of
Directors.  Members of  the Committee are  not eligible to  receive options. The
Committee determines, subject to the terms of the Plan, the individuals to  whom
options shall be granted, the time at which options shall be granted, the number
of options granted to each individual, the option price per share, and all other
matters necessary for administration of the 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  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  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
 
                                       21
 
<PAGE>
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.
 
     The  Plan provides  that the  options shall  be exercisable  in full  for a
period of thirty  (30) days following  the date of  a change in  control of  the
Company,  unless  exempted  by  the  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. The change in control provisions of  the
Plan  may  be  deemed  anti-takeover  provisions  in  that  they  may  result in
increasing the cost of  any proposed takeover by  (i) providing a mechanism  for
increasing the number of shares of Common Stock outstanding, (ii) providing that
exercisabilty  of options  granted pursuant  to the  Plan may  be accelerated in
certain events  and  (iii)  providing  for payment  of  cash  in  settlement  of
outstanding options.
 
     Payment  for shares of Common Stock of the Company upon exercise of a stock
option may be made in  cash, or in such other  form of consideration, as  deemed
appropriate by the Committee (including cashless exercise procedures), or shares
of Common Stock, or a combination of cash and shares of Common Stock.
 
     The  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 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 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.
 
     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
 
                                       22
 
<PAGE>
price  plus  the  amount  includable  as ordinary  income).  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.
 
     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 (1) year.
 
     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 Plan.
 
     THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS THAT SHAREHOLDERS VOTE FOR
THIS  PROPOSAL  TO  APPROVE THE  ADOPTION  OF  THE 1995  STOCK  OPTION  PLAN FOR
EMPLOYEES OF WITCO CORPORATION AND ITS SUBSIDIARIES.

     The Board of Directors has appointed  Ernst & Young LLP as the  independent

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.

Meeting with the opportunity to make a statement and respond to questions.

SECTION 4. ADMINISTRATION.
 
     The  Plan shall  be administered by  the Committee, which  shall consist of
three or more persons  who shall be  members of the Board  of Directors and  who
shall  be  disinterested persons  as defined  from  time to  time in  Rule 16b-3
promulgated by the Securities and  Exchange Commission pursuant to the  Exchange
Act.  The Committee shall be appointed by the Board of Directors, which may from
time to  time appoint  members  of the  Committee  in substitution  for  members
previously appointed and may fill vacancies, however caused, in the Committee.
 
     The  Committee will, in its discretion,  determine (subject to the terms of
the Plan) the officers and other key  employees to be granted Options, the  time
or  times at which Options shall be granted, and the number of Shares subject to
each Option, whether  the Options  are Incentive Stock  Options or  Nonqualified
Stock  Options, and the manner in which Options may be exercised. In making such
determination, the  Committee  may take  into  consideration the  value  of  the
services  rendered by  the respective  individuals, their  present and potential
contributions to the success of the Company and its Subsidiaries and such  other
factors  which the Committee  may deem relevant in  accomplishing the purpose of
the Plan.
 
     The Committee shall hold its  meetings at such times  and places as it  may
determine. A majority of the Committee shall constitute a quorum and the acts of
a  majority of the members present at any  meeting at which a quorum is present,
or acts approved in writing by a majority of the Committee, shall be deemed  the
acts  of  the Committee.  The  Company shall  grant  Options under  the  Plan in
accordance with determinations made by the Committee pursuant to the  provisions
of the Plan. The Committee from time to time may adopt (and thereafter amend and
rescind)  such rules  and provisions  for carrying  out the  Plan and  take such
action in the administration of the  Plan, not inconsistent with the  provisions
hereof,  as it  shall deem  proper. The  interpretation and  construction of any
provisions of the Plan  by the Committee shall,  unless otherwise determined  by
the  Board of  Directors, be  final and  conclusive. No  member of  the Board of
Directors or the Committee shall be liable for any action or determination  made
in good faith with respect to the Plan or any Option granted thereunder.
 
SECTION 5. OPTION SHARES.
 
     The  maximum number of Shares which may  be issued upon exercise of Options
under the  Plan shall  not exceed  2,600,000 Shares  (subject to  adjustment  as
provided  in Section  10). Notwithstanding any  other provision in  the Plan, no
person shall  be granted  Options for  more than  1,300,000 shares  (subject  to
adjustment  as provided in Section 10) during  the term of this Plan. The Shares
issued under the Plan may be either  issued Shares reacquired by the Company  at
any  time and  held in its  Treasury or  authorized but unissued  Shares, as the
Board of Directors from time to time may determine.
 
     In the event  that any outstanding  Options under the  Plan for any  reason
expire or are terminated, the Shares allocable to the unexercised portion of all
of  such Options shall again  be available for the future  grant of an Option or
Options under the Plan.
 
                                      A-3
 
<PAGE>
SECTION 6. ELIGIBILITY.
 
     Options will  be granted  only to  persons  who are  key employees  of  the
Company or its Subsidiaries. The term 'employees' shall include officers as well
as  other  key employees  of the  Company  or any  Subsidiary and  shall include
directors who are also employees of the Company or any Subsidiary.
 
     No Incentive Stock Option may be granted to any individual who, on the Date
of Grant, owns (within the meaning of Section 422(b)(6) of the Code) directly or
indirectly stock of the  Company possessing more than  ten percent (10%) of  the
total  combined voting power or value of all  classes of stock of the Company or
any Subsidiary.  For purposes  of  the preceding  sentence, direct  or  indirect
ownership  shall  be  determined in  accordance  with the  attribution  rules of
Section 424(d) of the Code.
 
     An individual may be granted more than one Option but only on the terms and
subject to the restrictions hereinafter set  forth. No person shall be  eligible
to  receive an Option for a larger number of Shares than is recommended for such
individual by the Committee.
 
SECTION 7. LIMITATION APPLICABLE ONLY TO INCENTIVE STOCK OPTIONS.
 
     To the extent that the aggregate Fair Market Value of the Shares determined
as of  the  Date  of  Grant  with  respect  to  which  Incentive  Stock  Options
(determined  without regard to  this sentence) are granted  to an Optionee after
1986 and are exercisable for the first time by an Optionee in any calendar  year
(under  all plans of the Company and its Subsidiaries) exceeds $100,000 (or such
other maximum amount which may hereafter  be specified under Section 422 of  the
Code),  such Options shall be  treated as Options which  are not Incentive Stock
Options by taking such Options into account in the order in which granted.
 
SECTION 8. TERMS AND CONDITIONS OF OPTIONS.
 
     Each Option granted  under the Plan  shall be evidenced  by a Stock  Option
Agreement  containing such terms and conditions, not inconsistent with the Plan,
as the  Committee shall  determine, provided  that such  Stock Option  Agreement
shall  clearly and separately identify  Nonqualified Stock Options and Incentive
Stock Options and that the substance of the following terms and conditions shall
be included therein:
 
          (a) Option Price. The Option Price at which each Share covered by such
     Option may be purchased shall be  determined by the Committee and shall  be
     no  less than 100 percent (100%) of the  Fair Market Value of the Shares on
     the Date of Grant.
 
          (b) Nontransferable.  The  Option shall  not  be transferable  by  the
     Optionee  otherwise than by will or by the laws of descent and distribution
     and may be exercised, during the Optionee's lifetime, only by the Optionee.
 
          (c) Exercise  After  Termination  of Employment.  Except  as  provided
     hereafter  in this paragraph (c), only  those Options exercisable as of the
     date  of  the  Optionee's  termination  of  employment  (determined   after
     application  of paragraph  (g) hereof) may  be exercised,  and such Options
     shall be  exercisable during  the  ninety (90)  day period  following  such
     termination,  provided that in no event  shall Options be exercisable after
     the expiration of ten  (10) years from  the Date of  Grant or such  earlier
     date  as may be  specified hereunder. Options granted  under the Plan shall
     not be affected by any change of duties or position so long as the Optionee
     continues  to  be   an  employee   of  the  Company   or  any   Subsidiary.
     Notwithstanding  the  foregoing  provisions  of  this  paragraph  (c), upon
 
                                      A-4
 
<PAGE>
     termination of employment by (i)  early retirement or normal retirement  by
     an   Optionee,  each  as  determined  pursuant  to  the  Witco  Corporation
     Retirement Plan, (ii) death or  (iii) disability as determined pursuant  to
     the  Witco Corporation  Long Term Disability  Plan, any  Option which would
     otherwise not then be exercisable shall become immediately exercisable  and
     such  Options  shall  be  exercisable  during  the  three  (3)  year period
     following such termination; provided, however,  that except in the case  of
     the death of the Optionee, the exercise of any Incentive Stock Option shall
     qualify  for Incentive Stock Option treatment only if the Optionee has been
     an employee of the Company or any Subsidiary at all times during the period
     beginning with the Date of Grant and ending on the day three (3) months (or
     one (1) year in the case of an Optionee permanently and totally disabled as
     defined in Section  22(e)(3) of the  Code) before the  Date of Exercise  of
     such  Option. In  the event  of any question  regarding the  meaning of the
     terms   'termination',   'early   retirement',   'normal   retirement'   or
     'disability' the determination of the Committee shall be final and binding.
     If any Optionee who has terminated employment for a reason other than death
     shall die holding an Option that is not fully exercised, such Option may be
     exercised,  to the extent it could have been exercised by the decendent, at
     any time within the  greater of one  year after such date  of death or  the
     remainder  of the  period in  which the  Optionee could  have exercised the
     Option had he or she not died, but in no event beyond the original term  of
     the Option.
 
          (d)  Term of Option. No  Option shall be exercisable  prior to six (6)
     months after the Date of Grant or  the date of shareholder approval of  the
     Plan,  whichever is later,  or after (i)  the expiration of  ten (10) years
     from the  Date of  Grant or  (ii) such  earlier date  as may  be  specified
     hereunder.
 
          (e)  Death of Optionee. In the event  of the death of an Optionee, any
     Option theretofore  granted to  such person  which is  then exercisable  as
     provided  in paragraph  (c) shall  be exercisable  only by  the executor or
     administrator of the Optionee's estate or by the person or persons to  whom
     the Optionee's rights under the Option shall pass by the Optionee's will or
     the laws of descent and distribution.
 
          (f)  No Right to  Continuance of Employment.  Nothing contained in the
     Plan or in any  Stock Option Agreement shall  confer upon any Optionee  any
     right  of continuance of employment by the Company or its Subsidiaries, nor
     interfere in  any  way  with  the  right of  the  Company  or  any  of  its
     Subsidiaries   to  terminate  the  Optionee's   employment  or  change  the
     Optionee's compensation at any time.
 
          (g) Dismissal  for Cause.  In the  event that  any Optionee  shall  be
     dismissed from the employ of the Company or any of its Subsidiaries for any
     reason  which  the  Committee  determines  to  constitute  good  cause  for
     dismissal, the Company shall notify such Optionee of such determination and
     any Option  still  held by  such  person at  such  time shall  be  canceled
     effective  as of the date of such Optionee's termination of employment. The
     decision of  the Committee  as  to what  shall  constitute good  cause  for
     dismissal shall be final and binding upon all concerned.
 
SECTION 9. EXERCISE OF OPTIONS -- PURCHASE OF SHARES.
 
     Unless  otherwise  determined by  the  Committee (subject  to  Section 8(d)
hereof), twenty percent (20%) of the total number of Shares subject to an Option
shall become exercisable one year from Date of Grant and twenty percent (20%) on
each of the four succeeding anniversaries, subject to the limitations imposed on
exercise in the Stock Option Agreement.  An Optionee's right to purchase  Shares
with  respect to  an Option which  becomes exercisable in  installments shall be
cumulative during  the term  of the  Option.  An Option  shall be  exercised  by
payment to the Company of the Option Price
 
                                      A-5
 
<PAGE>
accompanied by a written request specifying the number of Shares with respect to
which  such Option is  exercised on the  Date of Exercise.  However, the Company
shall not be required to issue or deliver any certificates for Shares  purchased
upon  the exercise of an  Option prior to the  completion of any registration or
other qualification of such shares under any state or federal law or rulings  or
regulations of any government regulatory body, which the Company shall determine
to be necessary or advisable.
 
     Payment  of the Option Price shall be  in cash, or such other consideration
as the Committee  shall determine in  its sole discretion,  to be  substantially
equivalent  to cash (including cashless exercise procedures), or by surrender of
stock certificates  representing like  common  stock of  the Company  having  an
aggregate Fair Market Value, determined as of the Date of Exercise, equal to the
number  of Shares with respect  to which such Option  is exercised multiplied by
the Option Price  per share;  provided that  the Committee  may impose  whatever
restrictions  it deems  necessary or desirable  with respect to  the payment for
Shares by the surrender of stock certificates representing like common stock  of
the Company.
 
     No   Optionee  or   Optionee's  executor  or   administrator,  legatees  or
distributees, as the case may be, will be, or will be deemed to be, a holder  of
any  Shares  subject  to an  Option  unless  and until  a  stock  certificate or
certificates for such  Shares are  issued to such  person or  persons under  the
terms  of the Plan and  Stock Option Agreement. No  adjustment shall be made for
dividends (ordinary  or  extraordinary, whether  in  cash, securities  or  other
property) or distributions or other rights for which the record date is prior to
the date such stock certificate is issued, except as provided in Section 10.
 
SECTION 10. CHANGE IN STOCK, ADJUSTMENTS, ETC.
 
     In  the  event  that  the outstanding  Shares  are  hereafter  increased or
decreased or changed  into, or exchanged  for, a different  number of shares  or
kind  of shares or  other securities of  the Company or  another corporation, by
reason   of    reorganization,    merger,    consolidation,    recapitalization,
reclassification,  stock split-up, combination of  Shares, or a dividend payable
in capital stock, appropriate adjustment shall  be made by the Committee in  the
number and the kind of Shares for purchase of which Options may be granted under
the Plan, including the maximum number that may be granted to any one person. In
addition,  the Committee shall make appropriate adjustments in the number and in
the kind of  Shares as to  which outstanding Options,  or portions thereof  then
unexercised,  shall be exercisable, to the end that the Optionee's proportionate
interest shall be maintained  as before the occurrence  of such event, and  such
adjustment  of outstanding  Options shall  be made  without change  of the total
Option Price applicable  to the  unexercised portion of  the Option  and with  a
corresponding  adjustment in the Option Price per share; provided, however, that
each such adjustment in the number and kind of Shares subject to the outstanding
Options, including any adjustments  in the Option Price,  shall be made in  such
manner  as not to constitute a modification  as defined in Section 424(h) of the
Code. Any such adjustment made by the Committee shall be conclusive.
 
     The grant of an Option pursuant to the Plan shall not affect in any way the
right  or  power  of  the   Company  to  make  adjustments,   reclassifications,
reorganizations  or changes in its capital or  business structure or to merge or
to consolidate or to dissolve, liquidate or sell, or transfer all or any part of
its business or assets.

SECTION 11. DURATION, AMENDMENT AND TERMINATION.
 
     The Board of  Directors may at  any time  terminate the Plan  or make  such
amendments  thereof as it shall  deem advisable and in  the best interest of the
Company, without further action on the part of the shareholders of the  Company;
provided,  however, that  no such  termination or  amendment shall,  without the
consent of  the  individual to  whom  any  Option shall  theretofore  have  been
granted,  affect or impair the rights of  such individual under such Option, and
provided further, that unless the shareholders  of the Company shall have  first
approved  thereof,  no  amendment  of  the Plan  shall  be  effective  for which
shareholder approval is required  in order to satisfy  the requirements of  Rule
16b-3  under Section  16(b) of the  Exchange Act,  the Code, the  New York Stock
Exchange, or any other applicable laws.
 
     It is intended that the Plan be applied and administered in compliance with
Rule 16b-3. If any provision of the Plan would be in violation of Rule 16b-3  if
applied as written, such provision shall not have effect as written and shall be
given  effect so as to  comply with Rule 16b-3,  as determined by the Committee.
The Board of  Directors is authorized  to amend the  plan and to  make any  such
modifications to Stock Option Agreements to comply with Rule 16b-3, as it may be
amended   from  time  to  time,  and  to  make  any  other  such  amendments  or
modifications as it deems necessary or appropriate to better the purposes of the
Plan in light of any amendments made to Rule 16b-3.
 
     No Option shall be granted under the Plan after March 1, 2005, but  Options
granted  prior to or as  of such date may extend  beyond such date in accordance
with the provisions hereof.
 
SECTION 12. EFFECTIVE DATE OF THE PLAN.
 
     The Plan shall be effective on the date approved by the Board of  Directors
(the  'Effective Date'), subject to the approval  of the Plan within twelve (12)
months of  its Effective  Date by  the shareholders  of the  Company. After  the
Effective  Date, the Options may  be granted as provided  herein subject to such
subsequent shareholder approval.
 
SECTION 13. DATE OF GRANT.
 
     The Date of Grant of an Option pursuant  to the Plan shall be the date  the
Committee's decision that an Option shall be granted becomes final or such later
date  as specified by the Committee. The  Company shall submit to the Optionee a
Stock Option Agreement duly executed by and  on behalf of the Company, with  the
request  that the Optionee execute such Agreement and return it to the Secretary
of the Company within thirty (30) days after it is mailed by the Company to  the
Optionee.
 
SECTION 14. NO OBLIGATION TO EXERCISE OPTION.
 
     Granting  of  an  Option shall  impose  no  obligation on  the  Optionee to
exercise such Option.
 
SECTION 15. WITHHOLDING TAXES.
 
     The Company's obligations to deliver Shares upon the exercise of any Option
shall be  subject  to  applicable  federal,  state  and  local  tax  withholding
requirements.  Accordingly,  the Company  may either  (i)  reduce the  number of
Shares otherwise issuable, subject to such limitations as may be imposed by Rule
16b-3 under Section  16(b) of the  Exchange Act, or  (ii) require  reimbursement
from  the holder  equal to the  withholding applicable under  federal, state and
local income tax laws and regulations.

SECTION 16. EFFECT OF CHANGE IN CONTROL OR TENDER OFFER.
 
     (a) Each Stock  Option Agreement entered  into pursuant to  the Plan  shall
provide  that Options granted under the Plan  shall be exercisable in full for a
period of thirty  (30) days following  the date of  a Change in  Control of  the
Company.
 
     (b)  A tender offer or exchange offer  for shares which results in a Change
in Control shall be deemed to constitute a Tender Offer.
 
     (c) All Options outstanding  at the end  of the thirty  (30) day period  in
subsection  (a) hereof shall be surrendered to  the Secretary of the Company for
cancellation in exchange for a settlement payment. The amount paid in settlement
for the surrender and cancellation of each Option shall be the higher of:
 
             (i) the excess of  the Fair Market Value  of the Shares subject  to
        the  Option  (regardless of  exercisability) at  the  end of  the period
        specified in subsection (a) hereof over the Option Price; or
 
             (ii) the  excess of  the 'Offer  Price per  Share' (as  hereinafter
        defined),  if any,  of the Shares  subject to the  Option (regardless of
        exercisability) over the Option Price.
 
     As used in subparagraph (ii) above, the term 'Offer Price per Share'  shall
mean the highest price per Share payable in any Tender Offer which was in effect
at  any time during  the period beginning sixty  (60) days prior  to the date on
which such Option was  surrendered. Any securities or  other property which  are
part  of the consideration paid for Shares in  a Tender Offer shall be valued in
determining the Offer Price per Share at the valuation placed on such securities
or property by the corporation, person or other entity making the Tender Offer.
 
     (d) The Committee at any time may exempt from the operation of  subsections
(a)  and (c)  hereof any  outstanding Option  selected by  the Committee  or may
exempt all outstanding Options. No exemption shall, however, be effective  after
payment  or delivery  of Shares  has been  made in  settlement of  a surrendered
Option.
 
     (e)  The  Committee  shall  have  sole  discretion  to  determine   whether
settlement  payments shall  be made  wholly in  cash, wholly  in Shares  or by a
combination of cash and Shares. In the event no action is taken by the Committee
to determine the method of payment, the amount due shall be paid in cash.
 
     (f) To the extent that the exercise of an Option during the thirty (30) day
period referred to  in subsection (a)  above or  the surrender of  an Option  as
provided  for in  subsection (c) above  would result in  liability under Section
16(b) of the Exchange Act  to an Optionee, the  Committee shall exempt from  the
operation  of  subsections (a)  and  (c) hereof  any  such Options,  pursuant to
subsection (d) above, until such time that the exercise of such Option would not
result in liability under Section 16(b) of the Exchange Act.
 
SECTION 17. OTHER TERMS.
 
     Stock  Option  Agreements  evidencing   Options  may  contain  such   other
provisions, not inconsistent with the Plan, as the Committee deems advisable.
