                             ELECTION OF DIRECTORS
 
     The number  of directors  comprising the  Board of  Directors is  currently
established  at  twelve directors,  divided into  three  classes. Each  class is
elected to serve  a three  year term,  and classes  are elected  on a  staggered
basis.  At the time  of the 1997  Annual Meeting of  Shareholders, there will be
three vacancies as the  Nominating Committee of the  Board of Directors has  not
yet  completed the process of selecting, interviewing, and nominating persons to
fill  these  vacancies.  Pursuant  to  the  Company's  Restated  Certificate  of
Incorporation, vacancies on the Board of Directors shall be filled by a majority
vote  of the  directors then in  office, and  the director so  chosen shall hold
office for a term expiring  at the annual meeting  of shareholders at which  the
term  of the class to which the director  has been elected expires. The Board of
Directors anticipates filling these vacancies pursuant to such provision in  the
Restated Certificate of Incorporation during 1997.
 
     The  number of directors to be elected  at the 1997 Annual Meeting is fixed
at three. The directors  who are nominated for  election by the shareholders  at
the  1997 Annual Meeting are Messrs.  Brinberg, Grant and Hayden. These nominees
were elected by the shareholders at  the Annual Meeting of Shareholders held  in
1994  for a three-year  term and each will  be elected to  hold office until the
Annual Meeting of Shareholders  to be held  in 2000, or  until his successor  is
elected  and qualifies. Proxies cannot be voted  for a greater number of persons
than these three nominees.
 
     Mr. E. Gary Cook was elected to the Board of Directors and as its Chairman,
on June  12, 1996,  effective June  13, 1996,  filling a  vacancy in  the  class
holding  office until the Annual Meeting of Shareholders to be held in 1998. Mr.
Cook will hold office  until the Annual  Meeting of Shareholders  to be held  in
1998, or until his successor is elected and qualifies.
 
     The  affirmative vote of the holders of a plurality of the shares voting at
the 1997 Annual Meeting of Shareholders having voting power present in person or
represented by proxy at the meeting is required for the election of each nominee
for director. Unless otherwise specified, the proxies received will be voted FOR
the election of the listed nominees.
 
     The nominees  for  director and  the  continuing directors,  their  present
principal  occupation or employment as of December 31, 1996, and other positions
held during the past five years are set forth below.

Committee is also authorized  to (a) adopt amendments  to the 401(k) plans,  (b)
periodically  review and adopt changes to the Company's stated long-term rate of
return on pension assets and the  actuarial assumptions and discount rates  used
for  accounting and financial reporting purposes  to ensure that it is supported

offered  under the  401(k) plans,  and (d) recommend  to the  Board of Directors
adoption of  retirement or  savings plan  benefits. The  Pension Committee  held
three meetings during 1996.
 
COMPENSATION OF DIRECTORS
 
     Non-employee   directors  are  paid  an  annual  retainer  of  $25,000,  an
attendance fee  of  $1,000  per  Board  meeting,  and  reimbursement  of  travel
expenses. Non-employee members of the Board of Directors who are chairpersons of
a  committee receive an attendance  fee of $1,000 per  meeting of the committee,
and other non-employee  members of committees  receive $750 per  meeting of  the
committee. Non-employee members of committees also receive an annual retainer of
$2,500  for each committee on which they serve. Any director entitled to receive
annual retainers and attendance fees has the option to elect to defer payment of
all or  any  part  of  such compensation  pursuant  to  the  Company's  Deferred
Directors'  Fees Plan, as amended, until their  retirement or such other time as
they have  elected pursuant  to  that plan.  Amounts  deferred can  either  earn
interest  at an annual  rate set forth in  such plan or  be converted to phantom
shares of Common  Stock which  earn additional phantom  shares on  each day  the
Company  pays  a  dividend.  The Company  provides  non-employee  directors with
coverage under the Company's basic  life and accidental death and  dismemberment
policy with a death benefit of $50,000.
 
     The  Company retained Mr. Wishnick, upon  his retirement as Chairman of the
Board and Chief Executive Officer, as  an independent consultant for the  period
February  1, 1991 through January 31, 1993 at an annual retainer of $100,000. On
October 22,  1992,  the Company  extended  the consultancy  agreement  with  Mr.
Wishnick  for the period February 1, 1993  through January 31, 1995 at an annual
retainer of $110,000.  Thereafter, the agreement  is automatically extended  for
additional terms of one (1) year each unless either party gives ninety (90) days
written notice of its intention not to continue such agreement. In addition, the
Company  makes office space and  a part-time secretary available  for use by Mr.
Wishnick.
 
DIRECTORS' STOCK OWNERSHIP REQUIREMENTS
 
     On March 4, 1997, the Board of Directors adopted stock ownership guidelines
for directors of the Company which  require that each director own Common  Stock
having  a value  equal to  three times total  annual compensation  received as a
director of the Company.  Each director has five  years to achieve the  required
level of ownership.

    The 1996 amounts shown  above in the Other  Annual Compensation column  also
    include  $5,450 for relocation expenses paid or reimbursed by the Company on
    behalf of Mr. Cook and a payment of $20,389 to Mr. Katz for reimbursement of

 (d) Dollar amount shown  equals number  of shares of  restricted stock  granted
     multiplied by stock price on grant dates. This valuation does not take into
     account the diminution in value attributable to the restrictions applicable
     to the shares. The value of the shares of restricted stock held on December
     31,  1996, based on a closing price of Common Stock on December 31, 1996 of
     $30.50, was $1,500,173 for Mr.  Cook. Thirty thousand shares of  restricted
     stock  issued  in  Mr.  Cook's  name  on  June  12,  1996  are  subject  to
     performance-based conditions and 19,186  shares of restricted stock  issued
     in  Mr. Cook's  name on September  19, 1996  vest as to  one-fourth of such
     shares on  each  of March  19  and September  19,  1997 and  March  19  and
     September 19, 1998. Dividends are paid on all shares of restricted stock at
     the  same rate  as on unrestricted  shares. See  'Employment Agreements and
     Other Arrangements' at page 18 of this Proxy Statement.
 
 (e) The stock options granted during 1996, 1995 and 1994 were granted  pursuant
     to  the 1995 Stock Option Plan and the  1992 Stock Option Plan which do not
     provide for tandem or stand alone stock appreciation rights.
 
 (f) Includes the Company's matching contribution under the Savings Plan in  the
     amount  of $4,800  for Messrs. Cook,  Katz, Jain, Toller  and Mahoney. With
     regard to  Mr.  DiFrancesco, the  amount  includes the  Company's  matching
     contribution  of $6,000 under the OSi  Specialties, Inc. 401(k) Savings and
     Investment Plan and  the payment of  group life insurance  premiums in  the
     amount of $281.

 (a) With  the exception of certain options  granted to Messrs. Cook, Toller and
     Mahoney on June 12,  1996, each option to  purchase shares of Common  Stock
     was  granted on June 4,  1996. Twenty percent of  the shares subject to the
     option grants,  with the  exception of  the options  for Mr.  Cook,  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. Fifty percent of
     Mr.  Cook's   options   vest   one   year   from   the   grant   date   and

     twenty-five  percent vest on each of the next succeeding anniversaries. Mr.
     Toller and Mr. Mahoney's options became immediately exercisable on June 12,
     1996 upon their respective retirements.
 
     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.
 
 (b) The  options were granted pursuant to the 1995 Stock Option Plan which does
     not provide for tandem or stand alone stock appreciation rights.
 
 (c) Payment for shares of Common Stock 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, shares of  Common
     Stock or a combination of cash and shares of Common Stock).
 
Stock Option Exercises
 
     The  following table provides information  regarding stock option exercises
by the  named  executive officers  during  the  year ended  December  31,  1996,
including  the aggregate  value realized on  the date of  exercise. In addition,
unexercised stock options  (both exercisable and  unexercisable) as of  December
31,  1996,  as well  as  the value  of  in-the-money unexercised  options (i.e.,
options which had  a positive  spread between the  exercise price  and the  fair
market  value of Common Stock as of December 31, 1996) have been included in the
table. The closing price of the Common  Stock on the New York Stock Exchange  on
December 31, 1996 was $30.50.

     having met the performance goals.
 
                             Certain Benefit Plans
 
Defined Benefit Pension Plan
 
     The  Company currently  has a  qualified, non-contributory  defined benefit
plan, the  Witco  Corporation Retirement  Plan  (the 'Retirement  Plan'),  which
covers executive officers and non-bargaining employees. Because the pension plan
was sufficiently funded, no contributions were made
 
                                       15
 
<PAGE>
<PAGE>
thereto  in 1996. The remuneration covered by the Retirement 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  earnings for  the 60  months
preceding  retirement) 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.

     As of December  31, 1996, Messrs.  Cook, Katz, Shinners,  Jain, Toller  and

respectively.
 
     During 1996, Mr.  DiFrancesco participated  in the  Retirement Program  for
Employees  of OSi Specialties,  Inc. and its  Participating Subsidiary Companies
(the 'OSi Plan'). As of December 31, 1996,

Mr. DiFrancesco had completed 3 years of  service under the OSi Plan. The  table
set  forth  above  illustrates  the estimated  annual  benefits  payable  to Mr.
DiFrancesco under the OSi  Plan. However, for purposes  of the OSi Plan,  'final
average  pay' is  defined as  average compensation  for the  36 months preceding
retirement.
 
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 was  a  participant in  certain  bonus plans  was  eligible to
participate in the Deferred Plan in  1996. 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 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.
 
Supplemental Executive Retirement Plan
 
     The  Board  of  Directors  amended  the  Company's  existing   Supplemental
Executive Retirement Plan (the 'SERP') on September 5, 1996. Participants in the
SERP 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  (or at or after age 62 if  approved
by  the Board of  Directors), 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  Retirement Plan  (or other  qualified
defined  benefit plan), the Excess Plan and  50% of the Social Security benefit.
If a participant retires and his retirement year bonus is higher than the  bonus
used  in the  calculation, the  SERP benefit is  adjusted to  reflect the higher
bonus.
 
     Estimated annual  target retirement  benefits under  all retirement  plans,
including  the SERP,  payable as  a 50%  joint and  survivor annuity  or 15 year
certain annuity (if unmarried)  at age 65 are  as follows, assuming future  base
salaries  remain at current levels and bonuses paid equal 60% of base salary for
Mr. Cook and  40% of  base salary for  Messrs. Katz,  DiFrancesco, Shinners  and
Jain:  Mr.  Cook  $591,800, Mr.  Katz  $182,600, Mr.  DiFrancesco  $180,900, Mr.
Shinners $173,900 and Mr. Jain $155,700.
 
     In the event  of death  prior to  the date  benefits are  to commence,  the
Company will pay a benefit to the executive's beneficiary.
 
     In  the  event  of  a change  in  control,  as defined  in  the  SERP, each
participant will be fully  vested in a  monthly supplemental retirement  benefit
commencing  at age 60 equal to one-twelfth  of the annual benefit which is equal
to 50% of  the sum  of the  participant's base  salary, bonus  and LTIP  amount,
reduced  by amounts paid  under the Retirement Plan  (or other qualified defined
benefit plan), the Excess Plan and 50% of the Social Security benefit. For  this
purpose,  base salary is defined  as the annual rate of  salary in effect on the
date employment terminates  (or if  higher the  rate in  effect on  the date  of
change  in control).  Bonus is  defined as the  highest bonus  awarded under the
Original OAIP (or
 
                                       17
 
<PAGE>
<PAGE>
other annual  bonus plan)  during  the 60  complete  months preceding  the  date
employment  terminates. If a  participant did not  receive a bonus  for the year
preceding the termination date, the target bonus  for such year is used (or,  if
higher,  the target bonus in the year preceding the change in control). The LTIP
amount means  the aggregate  value of  the award  made under  the LTIP  for  the
preceding three year bonus period, divided by three.
 
     In  the event of the actual or  constructive termination of employment of a
participant within three years after a change in control or prior to a change in
control at  the request  of any  person who  effects a  change in  control,  the
participant  will be entitled to one lump sum  in an amount equal to three times
the participant's base salary, bonus and LTIP amount, as such terms are  defined
above.  In addition, the participant receives (i) outplacement services, (ii) if
applicable, continuation of certain payments under any relocation policy,  (iii)
the  company car the participant is using as of the termination date, grossed up
for any income taxes payable  in respect of the transfer  of such car, and  (iv)
any  amounts accrued under other programs, including a pro-rated bonus under the
Original OAIP (or other applicable annual bonus plan) in respect of the year  in
which employment terminates.
 
     The  SERP further provides for the gross-up of payments that are subject to
an excise tax imposed by  Code Section 4999 as a  result of a change in  control
and  the payment of legal fees in  connection with any action to enforce payment
under the  SERP  following  a  change  in  control.  If  the  Witco  Corporation
Shareholder  Value Incentive  Plan is approved  by the shareholders  at the 1997
Annual Meeting, amounts realized under such  plan, that are subject to the  Code
Section 4999 excise tax, would not be covered by the SERP gross up provision.
 
     In  exchange for the protections afforded to a participant upon termination
of employment following  a change in  control, each participant  is bound for  a
period of two years following such termination not to (i) render services of any
nature  for compensation  to any  person nor  acquire any  significant financial
interest in any business in which the Company has been substantially engaged  on
or  prior to the date employment terminates, or (ii) solicit any employee of the
Company to terminate  his or her  employment. In addition,  each participant  is
bound  not  to disclose,  divulge  or make  accessible  to any  third  party any
information of a secret or confidential  nature known to the participant in  the
course of his or her employment with the Company until such information has come
into the public domain or has otherwise ceased to be secret or confidential.
 
EMPLOYMENT AGREEMENTS AND OTHER ARRANGEMENTS
 
     Mr. Cook and the Company are parties to an employment agreement, dated June
12,  1996. The agreement is  for an initial term of  three years from that date,
and thereafter continues  for annual  periods unless either  party provides  six
months  written notice that the agreement shall not continue. In addition to the
right to participate in  the future in compensation,  benefit and welfare  plans
available to other executive officers of the Company, the agreement provides for
the  following: (a) annual base salary of $750,000; (b) a target award of 17,800
shares of Common Stock (two-thirds of  which are restricted) under the LTIP  for
the  1996-1998 performance  period; (c)  options to  purchase 800,000  shares of
Common Stock; (d) an  award of 30,000 restricted  shares of Common Stock,  which
restrictions  lapse as to one third of such shares if the Common Stock reaches a
fair market  value for  five consecutive  trading days  of $42.50,  $53.125  and
$66.00  per share, respectively;  (e) a signing bonus  of $1,000,000 payable one
half upon execution of the agreement and one half not later than March 31, 1997;
and (f)  restricted  shares  of  Common  Stock  having  a  value  equal  to  the
difference, if any, between the value of
 
                                       18
 
<PAGE>
<PAGE>
shares  of Mr. Cook's former employer on  the date Mr. Cook exercises options to
purchase such shares, and $23.00.
 
     The agreement also provides,  notwithstanding certain provisions  contained
in  the  SERP, Mr.  Cook  will be  entitled to  40%  of the  normal supplemental
retirement benefit upon retirement  as an active officer  of the Company  within
three  years of his commencement of employment, 60% if such retirement occurs on
or after three years of employment but before completion of five years and  100%
if such retirement occurs on or after five years of employment.
 
     The  agreement provides  that if  the employment  arrangement is terminated
during its term by the Company other than by reason of death, disability or  for
cause,  or if  Mr. Cook  terminates the agreement  for good  reason, the Company
shall pay to  Mr. Cook the  aggregate of  the following amounts  within 30  days
after  termination of employment: the sum of (i) base salary through the date of
termination, (ii) a prorated portion of the bonus targeted for the fiscal  year,
(iii)  any deferred compensation,  and (iv) the  amount equal to  the product of
three  times  annual  compensation  based   on  his  five  year  average   total
compensation amounts.
 
     As stated above, Mr. Toller and Mr. Mahoney retired from their positions as
executive officers of the Company during 1996. Retirement agreements, dated June
12, 1996, between each of Mr. Toller and Mr. Mahoney and the Company provide for
continued  payments equivalent to salary payments  for 1996 through December 31,
1996, an  additional award  of stock  options, acceleration  of outstanding  and
unvested  options, entitlement to awards under the Original OAIP and the LTIP as
if employed through  December 31, 1996,  normal retirement benefits,  commencing
effective  July 1, 1996, based on the  Retirement Plan's pension formula on that
date and payments  under the  Company's Executive Benefit  and Compensation  Cap
Plan  and the  SERP. In  addition, Mr. Toller  will receive  monthly payments of
$4,000 until June 30, 2001 to be used to maintain an office for his use.
 
TRANSACTIONS WITH MANAGEMENT
 
     In 1996, the Company adopted  Stock Ownership Guidelines for the  Company's
executive  officers  which  must  be  achieved  within  five  (5)  years.  These
guidelines establish minimum  levels of  stock ownership as  follows: the  Chief
Executive  Officer -- stock having  a value equal to  three times salary; senior
officers -- stock  having a  value equal  to two  times salary;  and, all  other
officers  -- stock having a value equal to  one times salary. In order to assist
and encourage executive officers to reach these ownership guidelines as soon  as
possible,  the Executive  Loan Program  and Enhanced  Stock Acquisition Program,
both described  below,  were established.  See  also 'Proposal  4:  Proposal  to
Approve  the Witco  Corporation 1997  Stock Incentive Plan'  at page  31 of this
Proxy Statement  and 'Proposal  5:  Proposal to  Approve the  Witco  Corporation
Officers' Annual Incentive Plan' at page 37 of this Proxy Statement.
 
Executive Loan Program
 
     A  loan facility (the 'Facility') has  been established with Fleet National
Bank ('Fleet') under which Fleet will make unsecured loans to executive officers
of the Company and  under the Facility the  Company will guarantee repayment  of
the loans. Participating officers agree with the Company that loan proceeds will
be  used  to purchase  Common Stock  and  that they  will indemnify  the Company
against any liability the  Company may incur under  its guarantee. Loan  amounts
are  limited to the multiple of executive  officer salary which equals the stock
ownership  multiple.  Each  loan  has  a  five  (5)  year  term.  As  additional
compensation,  the  Company  may  establish  a  program  under  which  executive
 
                                       19
 
<PAGE>
<PAGE>
loans are prepaid, but no more than one-third of the loan amount will be prepaid
by the Company in any  one year. The amount and  the timing of the  pre-payments
will  be  based on  criteria established  by  the Organization  and Compensation
Committee from time to time. All  amounts borrowed pursuant to the Facility  and
not  prepaid by the Company must be repaid by the executive officer. On December
30, 1996, Mr. Cook entered into such  a loan agreement with Fleet for an  amount
of $1,000,000, for the purpose of purchasing shares of Common Stock.
 
Enhanced Stock Acquisition Program
 
     To  the extent any executive officer purchases Common Stock with funds from
any source other than the Facility, the Company will grant the executive officer
one share of restricted stock for each two shares so purchased. The restrictions
on these restricted shares  lapse three years  from the date  of grant. At  this
time,  the Company intends to  purchase in the open  market all shares of Common
Stock required  to  be issued  as  restricted  shares under  this  program,  but
reserves  the right  to issue restricted  shares under the  1997 Stock Incentive
Plan, if such plan is approved by the Company's shareholders at the 1997  Annual
Meeting of Shareholders.
 
INDEBTEDNESS OF MANAGEMENT
 
     In connection with the relocation of Roger Sharp, the Company's Senior Vice
President,  Global Operations, to the Company's headquarters area and as a means
to provide him  with housing,  the Company has  loaned Mr.  Sharp $535,509  with
recourse,  which loan is evidenced by a non-interest bearing note and secured by
a first mortgage on his residence.
 
             REPORT OF THE ORGANIZATION AND COMPENSATION COMMITTEE
 
THE COMMITTEE'S ROLE
 
     The Organization and Compensation Committee (the 'Committee') is  comprised
entirely  of  non-employee  members of  the  Company's Board  of  Directors (the
'Board'). The Committee  reviews and recommends  to the Board  for approval  the
Company's  executive compensation policies and  programs, and amendments to such
policies and programs.  The Committee reviews  and recommends to  the Board  for
approval  all  compensation  payments to  the  Chief Executive  Officer  and the
Company's other  executive officers,  and the  aggregate incentive  compensation
payments of all employees of the Company. In addition to these responsibilities,
beginning  1995 the Committee acted on behalf  of the Board in the screening and
interviewing of candidates to become the Company's new Chairman of the Board and
Chief Executive Officer.  Following this process,  the Committee recommended  to
the  Board that Mr. Cook be selected as the Company's new Chairman of the Board,
Chief Executive Officer and President to replace the retiring Chairman and Chief
Executive Officer.
 
     To carry out its responsibilities, the Committee met ten times during 1996.
 
OBJECTIVES OF THE EXECUTIVE COMPENSATION PROGRAM
 
     The Company's executive compensation program is designed to attract, retain
and motivate the  high caliber  of executives required  for the  success of  its
business.  The  purpose  of this  program  and  the specific  objectives  of the
Committee are to:
 
                                       20
 
<PAGE>
<PAGE>
           Pay for performance, motivating both long- and short-term performance
           for the benefit of the Company's shareholders;
 
           Provide a  total  compensation  program  competitive  with  those  of
           companies  with which the Company  competes for top management talent
           on a global basis;
 
           Place greater  emphasis  on variable  incentive  compensation  versus
           fixed  or base pay, particularly for the Company's executive officers
           and to a lesser extent all of the Company's employees;
 
           Reward executives primarily on corporate performance;
 
           Require significant Common Stock ownership by the Company's executive
           officers and directors in order  to align their interests with  those
           of the Company's shareholders; and
 
           Most  importantly,  join  shareholder  and  management  interests  in
           achieving superior performance which should translate into a superior
           total return to shareholders.
 
     Overall, the Company's  executive compensation  program is  designed to  be
performance-oriented,  with a large portion of executive compensation 'at risk'.
The portion  of  the total  compensation  represented by  annual  and  long-term
incentives  that relate directly to performance  would, if targets were achieved
under  the  Company's   plans,  constitute  approximately   56%  of  the   total
compensation of the Company's executive officers at the end of 1996.
 
     The  Committee attempts 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'). 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, as the Committee believes that it competes for talent in a
relevant market which is broader than those companies against which it  directly
competes.
 
     In   1996  the  Committee  attempted   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. In  performing its  role, the  Committee reviews  information  from
various  sources,  including  proxy  statement  surveys,  industry  surveys, and
external compensation consultants.
 
POSITION ON DEDUCTIBILITY OF COMPENSATION
 
     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 unless the  Company complies with  certain conditions in  the
design  and administration of its  compensation programs. However, the Committee
reserves  the  right,  under  appropriate  circumstances  or  where  merited  by
individual  performance, nevertheless  to authorize  compensation payments which
may not be fully tax deductible by the Company.
 
OVERVIEW OF EXECUTIVE COMPENSATION AND 1996 COMMITTEE ACTIONS
 
     In furtherance  of  the  Committee's  objectives,  the  Company's  existing
executive  compensation program has four  principal components: (1) base salary,
(2) annual cash incentives under the Original
 
                                       21
 
<PAGE>
<PAGE>
OAIP, (3) stock options under the 1992  Stock Option Plan and 1995 Stock  Option
Plan (collectively, 'SOPs'), and (4) awards of stock under the LTIP.
 
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  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. 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.  In 1996, the  Committee's
goal  was to  bring executive officer  salaries, where deficient,  to the median
base salaries for comparable positions in the Comparison Group.
 
     In addition to the ongoing base  salary program, in 1996 certain  executive
officers retired or resigned their employment in connection with the appointment
of  the  Company's  new  Chairman  of the  Board,  Chief  Executive  Officer and
President. While the Company's retirement plans, including the SERP, provide the
form and amount of  payments retiring executive  officers normally receive,  the
Committee determined in 1996 that the retiring Chairman and Vice Chairman of the
Board  should each receive special additional compensation in view of their long
service and  valuable contributions.  For executive  officers who  resign  their
employment  as a  part of  the realignment  of the  executive management  of the
Company, but  who  are  not  eligible for  retirement,  the  Committee  provides
severance  sufficient to  permit the  executive officer  to transition  to other
employment. The form and amount of the severance is determined on a case by case
basis under a subjective  analysis which considers  past performance, length  of
service, and scope of responsibilities.
 
THE OFFICERS' ANNUAL INCENTIVE PROGRAM
 
     The  Original  OAIP  covering  1996  provides  for  annual  cash  incentive
compensation  based  on  various  performance  measures  for  executive  officer
positions.  Cash incentives are paid under the Original 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% if outstanding levels of performance are achieved.
 
     In  1996  the  most  important  performance  criterion  for  all  executive
officers, other than those having direct responsibility for the profitability of
assigned  business units, was  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.  Incentive  awards  for  these
executive  officers can be increased or decreased  up to 30% to reflect personal
performance factors and contributions.
 
                                       22
 
<PAGE>
<PAGE>
     For  those  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 or may not be reflected in financial results. For 1997 and thereafter,
the  Board has terminated the Original  OAIP and adopted, subject to shareholder
approval a revised Officers'  Annual Incentive Plan.  This revised OAIP  differs
from  the Original  OAIP in  that it contemplates  payment of  bonuses in Common
Stock and is designed to qualify as 'performance-based compensation' within  the
meaning  of Code Section  162(m)(4)(C). See 'Proposal 5  Proposal to Approve the
Witco Corporation Officers'  Annual Incentive  Plan' at  page 37  of this  Proxy
Statement.
 
STOCK OPTION PLANS
 
     The  SOPs are designed to reward employees directly for appreciation in the
long-term price of the Company's stock. The SOPs directly link the  compensation
of  executive  officers to  gains by  the  shareholders and  encourage executive
officers to adopt a  strong ownership orientation in  their work. The SOPs  also
place  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, 1995, and 1996, respectively, shareholders approved the 1992 Stock
Option  Plan, the  1995 Stock Option  Plan, and  an amendment to  the 1995 Stock
Option Plan. The 1992 Stock Option Plan replaced all earlier stock option  plans
in  effect and  the 1995  Stock Option  Plan supplemented  the number  of shares
available for issuance  under the 1992  Stock Option 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.
 
     With the understanding that the value (if any) of stock options is based on
future performance, the Committee has based 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 exceptionally strong corporate or individual performance.
 
LONG TERM INCENTIVE PLAN
 
     The LTIP is a long-term incentive  plan tied to the Company's  performance.
The  LTIP is designed to motivate the Company's most senior executives, as their
efforts most affect Company performance, and  to link their compensation to  the
Company's long-term financial objectives. The LTIP was approved by the Company's
shareholders  at the 1996  Annual Meeting of  Shareholders. The LTIP compensates
senior executives who  participate in the  plan for performance  over three  (3)
year  performance periods. Within  90 days after the  commencement of each three
(3) year performance period, the  Committee determines which executive  officers
will  participate  in  the  LTIP  for  the  performance  period,  and  for  each
participant: (i) the applicable performance  measure for the performance  period
(the  performance measures available for selection  by the Committee are defined
in the LTIP); (ii)  the performance target for  each performance measure;  (iii)
the    number   of   shares   of   Common   Stock   to   be   awarded   if   the
 
                                       23
 
<PAGE>
<PAGE>
performance target  is  achieved  during the  performance  period  (the  'Target
Award'); and (iv) the range of percentage of the Target Award to be awarded upon
the attainment of various percentages of the performance target.
 
     Awards  under the LTIP are  made in Common Stock.  Shares awarded under the
LTIP will consist  of one-third  unrestricted shares  and two-thirds  restricted
shares.  So long as  the performance period  ends at the  close of the Company's
fiscal year, the restrictions on one-half of the restricted shares will lapse on
the January 1  immediately following the  date the shares  are awarded, and  the
restrictions  on  the  remainder will  lapse  on  the following  January  1. The
Committee has the discretion to reduce any participant's award.
 
COMPENSATION OF THE CHIEF EXECUTIVE OFFICER
 
     In 1996, the Board appointed a  new Chief Executive Officer. The  Committee
screened  and interviewed candidates for this  position. Upon completion of this
process, the Committee recommended to the Board that E. Gary Cook be selected as
the new Chief  Executive Officer with  compensation as also  recommended by  the
Committee.  Following approval of the  Committee's recommendations by the Board,
Mr. Cook and the Company entered into an employment agreement on June 12,  1996.
In  order  to attract  and retain  Mr. Cook  and ensure  to the  greatest extent
possible the continued services of Mr. Cook over a period of time sufficient  to
permit  him  to  develop  and  implement  important  strategic  initiatives, the
Committee determined that it  was both necessary and  appropriate to enter  into
the employment agreement.
 
     In establishing the new Chief Executive Officer's compensation as reflected
in  the  employment agreement,  the  Committee considered  (i)  the compensation
packages provided to other chief executive officers in the Comparison Group,  as
well  as entities generally of the same size and complexity as the Company; (ii)
Mr.  Cook's  abilities  and  past   performance  in  the  industry;  (iii)   the
relationship  of the compensation to the success of the Company; (iv) Mr. Cook's
past compensation history; (v) the scope of the responsibilities assumed at  the
Company;  (vi)  the  amount  of  compensation  placed  at  risk;  (vii) internal
compensation levels at the Company; and (viii) the difficulty of the services to
be performed in view of the level  of change required in the Company's  business
processes,  systems,  organization,  personnel,  development  and  operations to
permit the  Company to  achieve sustainable  long-term financial  and  strategic
improvement.  No specific weighting was assigned to these factors in determining
the Chief Executive Officer's compensation.
 
     Mr. Cook's annual  salary under  the employment  agreement was  established
based  on  the  Committee's  review of  compensation  of  other  chief executive
officers, Mr. Cook's  significant experience  and success in  the industry,  his
past  compensation history, internal compensation levels at the Company, and the
difficulty of the services to be performed. Mr. Cook's grant of shares under the
Company's LTIP, the grant of stock options and the award of restricted stock for
which restrictions terminate if the Common Stock reaches certain trading  levels
(collectively, the 'Stock Compensation') were based on the goal of the Committee
to establish a strong connection between his compensation and the success of the
Company,  and to cause a  significant amount of compensation  to be at risk. The
Stock Compensation represents 79.2% of Mr. Cook's total compensation,  including
his  one-time  signing  bonus. The  Stock  Compensation  also gives  Mr.  Cook a
significant stake in the Company completely  aligned with that of the  Company's
shareholders.  The signing bonus provided to Mr.  Cook was in recognition of the
difficulty of the services to  be performed and the  desire of the Committee  to
obtain  his services on a  competitive basis in view  of his industry experience
and success. The Company's obligation to provide
 
                                       24
 
<PAGE>
<PAGE>
Mr. Cook with  restricted stock to  cover the  long term loss  of stock  options
granted  by  his former  employer was  tied to  the need  to recognize  his past
compensation history as  a part of  the competitive factors  to be addressed  in
order to retain Mr. Cook's services.
 
THE FUTURE
 
     The  Committee believes that the  Company should significantly increase the
portion of total  compensation represented  by annual  and long-term  incentives
that  relate directly  to performance.  The Committee  recommended to  the Board
changes and additions to  the Company's incentive  compensation plans and  these
recommendations, including the plans submitted to the Company's shareholders for
approval  and described in  this Proxy Statement, will  tie approximately 70% of
executive officer compensation  to annual  and long-term  incentives related  to
performance.
 
     The Committee believes that linking a significant portion of an executive's
current and potential future net worth to the Company's success, as reflected in
the  stock price, gives the  executive a stake similar  to that of the Company's
shareholders and  results  in long-term  management  for the  benefit  of  those
owners.  Consistent with  this philosophy, in  1996 the  Committee adopted Stock
Ownership Guidelines for the Company's executive officers which must be achieved
within five years. These guidelines establish minimum levels of stock  ownership
as  follows: the Chief Executive Officer --  stock having a value equal to three
times salary; senior officers -- stock having a value equal to two times salary;
and, all other officers --  stock having a value equal  to one times salary.  In
the  future it is anticipated  that a percentage of OAIP  awards will be paid in
Common Stock, if the revised  OAIP is approved by  the shareholders at the  1997
Annual Meeting.
 
     The  Committee believes  these compensation  practices will  help to ensure
alignment with the interests of the Company's shareholders.

                                   PROPOSAL 2
          PROPOSED RATIFICATION OF APPOINTMENT 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 1997 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  having voting  power present  in
person  or represented  by proxy  at the  meeting, the  selection of independent
auditors will be reconsidered by the Board of Directors.
 
     A member of Ernst & Young LLP is expected to be in attendance at the Annual
Meeting with the opportunity to make a statement and respond to questions.
 
     THE  BOARD  OF  DIRECTORS  RECOMMENDS  A  VOTE  FOR  RATIFICATION  OF   THE
APPOINTMENT OF ERNST & YOUNG LLP AS THE COMPANY'S INDEPENDENT AUDITORS.
 
                                   PROPOSAL 3
                   PROPOSAL TO APPROVE THE WITCO CORPORATION
                        SHAREHOLDER VALUE INCENTIVE PLAN
 
     At a meeting held on March 4, 1997, the Board of Directors adopted, subject
to  shareholder approval, the Witco Corporation Shareholder Value Incentive Plan
(the 'SVIP'). The SVIP is designed to  promote the interests of the Company  and
its shareholders by providing selected officers and employees of the Company and
its   subsidiaries  with  a  strong   incentive  to  increase  dramatically  the
shareholder value of the Company by  increasing the share price of Common  Stock
to  at least  $75 5/8  for a period  of ten  consecutive trading  days and/or by
increasing earnings per share to at least $4.50 per share (each a 'Target'  and,
collectively,  'Targets'). A copy of the SVIP is annexed to this Proxy Statement
as Exhibit  A and  should be  read in  its entirety.  The following  is a  brief
summary of the significant provisions of the SVIP.
 
     The  SVIP,  along  with the  other  two  plans under  consideration  by the
shareholders, comprises an integral  part of the  Company's efforts to  increase
stock  ownership by corporate executive officers (and certain other employees of
the Company and its subsidiaries)  and align their interests with  shareholders.
Under  the SVIP, each  participant is granted  an award of  Series B Convertible
Preferred Stock  ('Preferred  Stock').  Initially the  Preferred  Stock  is  not
convertible  and is  subject to  substantial restrictions.  If either  Target is
achieved by March 4, 2002, each share of Preferred Stock automatically  converts
into  10 shares of Common  Stock. If a change in  control of the Company occurs,
each share of Preferred  Stock automatically converts into  10 shares of  Common
Stock,  but unless the price paid for any share of Common Stock in the change of
control is more than $55 5/8 per share, and at least $10 per share greater  than
the  stock price  of the  Common Stock on  the date  of grant,  all Common Stock
obtained upon conversion shall be transferred to the Company. If the price  paid
in  the change of control for  any share of Common Stock  is between $55 5/8 and
$75 5/8 per share, and at least $10  greater than the stock price of the  Common
Stock  on the  date of  grant, five percent  (5%) of  the Common  Stock shall be
transferred to the  Company for each  whole dollar that  the stock price  Target
exceeds the change in control price.

ADMINISTRATION
 
     The SVIP is administered by a committee of the Board of Directors comprised
of  at least  two or  more 'outside  directors' (within  the meaning  of Section
162(m)(4)(C) of the Code) all of  whom are 'non-employee directors' (within  the
meaning  of  Rule  16b-3  promulgated under  the  Exchange  Act.  Presently, the
Organization and Compensation Committee serves as the Committee.
 
SHARES AVAILABLE
 
     Pursuant to the authority conferred upon the Board of Directors by  Article
IV  of the Restated  Certificate of Incorporation  of the Company,  the Board of
Directors designated 200,000 shares  of Preferred Stock to  be issued under  the
SVIP.  The Preferred  Stock is not  registered and, because  of the restrictions
imposed by the SVIP, is not transferable and is subject to a substantial risk of
forfeiture. The Preferred Stock has no  voting rights other than as required  by
law and no dividend rights. Upon attainment of either of the Targets, each share
of  Preferred Stock  automatically converts into  10 shares of  Common Stock. If
neither of  the Targets  is  achieved prior  to March  5,  2002, all  shares  of
Preferred Stock will be forfeited to the Company and shall become authorized and
unissued shares of non-designated preferred stock.
 
     On  March 4, 1997, the closing price of  Common Stock on the New York Stock
Exchange was $30 5/8 per share.
 
     The number  of  shares of  Preferred  Stock  available under  the  SVIP  is
200,000,  reduced by the aggregate number of  shares granted. On or before March
4, 2002 to the extent that shares  of Preferred Stock issued under the SVIP  are
forfeited  to the Company pursuant to the provisions of the SVIP, such number of
shares shall immediately be transferred to the Company and become available  for
reissuance  under the SVIP. The maximum number of shares of Preferred Stock that
may be issued to any SVIP participant is 100,000 shares.
 
ELIGIBILITY AND PARTICIPATION
 
     Eligibility to participate in the SVIP is limited to executive officers and
key employees who have been employed by  the Company or its subsidiaries for  at
least  six consecutive months. The decision as to which employees will receive a
stock grant will be made by the  Committee in its sole discretion. There are  18
executive  officers and  approximately 60  key management  employees who  may be
eligible for the SVIP.
 
TARGETS
 
     The Target under the SVIP is  achieved on the date the Committee  certifies
that either (i) the price per share of Common Stock, as reported on the New York
Stock Exchange, has remained at or above $75 5/8 for a period of ten consecutive
trading  days;  or  (ii)  the  earnings  per  share  of  the  Company  (and  its
subsidiaries) for any year of the Company is at least $4.50.
 
STOCK GRANTS
 
     Stock grants under  the SVIP will  be made at  the time and  in the  number
determined  by the Committee.  Each stock grant  will be evidenced  by a written
subscription agreement that shall contain within it (i) noncompetition covenants
that apply for two years following resignation and
 
                                       28
 
<PAGE>
<PAGE>
(ii) confidentiality covenants. Preferred Stock  issued to participants will  be
restricted  and may not  be transferred other than  in the limited circumstances
provided in the SVIP  (e.g., transfer to a  family member). The restrictions  on
the Preferred Stock lapse on the date the Committee certifies that either of the
Targets  has been achieved. The Preferred Stock is also subject to a substantial
risk of forfeiture because  if either of  the Targets has  not been achieved  by
March  4, 2002,  the Preferred Stock  is forfeited  to the Company  and shall be
retired and resume the status of authorized and unissued preferred shares.
 
CHANGE IN CONTROL
 
     Upon  a  change  in  control  of  the  Company,  the  Preferred  Stock   is
automatically   converted  into  10   shares  of  Common   Stock.  However,  the
subscription agreements under which  shares of Preferred  Stock are issued  will
provide  that if the change in control price  is not greater than $55 5/8 and at
least $10 greater than the  Common Stock price on the  date of grant the  entire
stock  grant is  forfeited and  the shares  of Common  Stock received  upon such
change in control are transferred to the Company. If the change in control price
is more than $55 5/8  (and at least $10 greater  than the Common Stock price  on
the  date of grant) but less than $75  5/8, the SVIP provides that the number of
shares of Common  Stock to  be forfeited  is 5% of  the shares  of Common  Stock
received  upon the change in control for  each whole dollar that the stock price
Target exceeds  the change  in control  price. The  subscription agreement  will
provide  that  if, following  a  change of  control,  either of  the  Targets is
achieved in the same year as that  in which the change of control occurred,  the
Company  shall pay, within 90 days following the end of such year, to any holder
of Preferred Stock immediately prior to the change of control an amount of  cash
equal  to the difference, if  any, between (A) the product  of (i) the change of
control price multiplied by (ii) the number  of shares of Common Stock, if  any,
received  by such  holder as  a result  of the  change of  control, and  (B) the
product of  (i)  ten  times  the  number of  shares  of  Preferred  Stock  owned
immediately  prior to  the change  of control multiplied  by (ii)  the change of
control price.
 
     In the event of  the commencement of  an exchange or  tender offer for  the
Company's  outstanding Common Stock upon consummation of which the offeror would
become the beneficial owner of 20% or  more of the Company's voting stock,  each
holder  of Preferred Stock shall elect (prior to the consummation of such offer)
to receive at the time of the consummation of such offer (i) a number of  shares
of Common Stock as determined in the first and second sentences of the paragraph
above,  or (ii)  so long as  the cash or  other value received  by the Company's
shareholders upon the consummation of the offer exceeds $55 5/8 per share and is
at least $10 greater than the share price of Common Stock on the date of  grant,
an  amount in cash equal to the product of (x) ten times the number of shares of
Preferred Stock held  (reduced by 5%  for each  whole dollar the  cash or  other
value paid per share of Common Stock paid upon consummation of the offer is less
than $75 5/8) multiplied by (y) the amount of cash or other value paid per share
of  Common Stock upon  consummation of the offer.  If, following consummation of
the offer, either of the Targets is achieved  in the same year as that in  which
the  offer was consummated, the Company shall  pay, within 90 days following the
end of such year, to  any holder of Preferred Stock  who elected as provided  in
subclause  (ii)  of  the preceding  sentence  an  amount of  cash  equal  to the
difference, if any, in the amount of  cash paid to such holder pursuant to  such
subclause  (ii)  and  the product  of  (A) ten  times  the number  of  shares of
Preferred Stock owned immediately prior  to making such election, multiplied  by
(B)  the amount  of cash  or other  value paid  per share  of Common  Stock upon
consummation of the offer.

     The number of  shares of  Common Stock into  which the  Preferred Stock  is
convertible  and each of the Targets may be  adjusted from time to time upon the
occurence of certain corporate events. See the 'Certificate of Designations' set
forth on Appendix A to Exhibit A of this Proxy Statement.
 
AMENDMENT AND TERMINATION
 
     The SVIP may be amended or terminated by the Board of Directors at any time
but generally  an amendment  may  not, without  the  consent of  a  participant,
adversely   affect  or   impair  a   right  available   under  a   stock  grant.
Notwithstanding this provision, the Committee may provide for the forfeiture  of
Preferred Stock and the transfer to the Company of such shares if it determines,
in  its complete discretion, that a participant has engaged in activity which is
contrary to the  interests of the  Company, its subsidiaries  or affiliates.  No
amendments  may be  made to  increase the  number of  shares of  Preferred Stock
available for grant without shareholder approval  or to make such other  changes
for which shareholder approval is required under Section 162(m) of the Code.
 
CURRENT DETERMINATION OF AWARDS
 
     On  March 4, 1997,  the Committee authorized  the following Preferred Stock
issuances under the SVIP, subject to shareholder approval:
 
                               NEW PLAN BENEFITS

     If the Target is realized by virtue  of achieving a stock price of $75  5/8
for  ten consecutive trading days, the amounts payable to the executive group as
a whole and to  all key employees would  represent approximately 2.8% and  4.3%,
respectively, of the amount that would be realized by the Company's shareholders
in the aggregate.
 
U.S. FEDERAL TAX ISSUES
 
     A  participant granted Preferred Stock will not recognize taxable income on
the date  of  grant.  At  the time  restrictions  lapse,  the  participant  will
recognize  ordinary income and  the Company will be  entitled to a corresponding
deduction equal to the excess  of the fair market value  of the Common Stock  on
the  date restrictions lapse over  any amount originally paid  in respect of the
stock grant.
 
                                       30
 
<PAGE>
<PAGE>
     If amounts are payable as a result of a change in control, all or a portion
of the  amounts  realized  under  this SVIP  may  be  characterized  as  'excess
parachute  payments'. If amounts are characterized as excess parachute payments,
the amount of the payment (as well as  any other payments that are in excess  of
the  participant's 'base  amount' (generally,  one times  the participant's most
recent five-year average W-2 compensation)) would be subject to a 20% excise tax
payable by the participant and would be nondeductible to 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 SVIP.
 
     THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS THAT SHAREHOLDERS VOTE FOR
THIS PROPOSAL TO APPROVE THE ADOPTION OF THE SVIP.
 
                                   PROPOSAL 4
                   PROPOSAL TO APPROVE THE WITCO CORPORATION
                           1997 STOCK INCENTIVE PLAN
 
     At a meeting held on March 4, 1997, the Board of Directors adopted, subject
to shareholder approval, the  Witco Corporation 1997  Stock Incentive Plan  (the
'SIP').  The SIP  is designed to  promote the  interests of the  Company and its
shareholders by (i) providing selected officers and employees of the Company and
its subsidiaries and affiliates with incentives to devote their best efforts  to
the Company by aligning employees' interests with the interests of the Company's
shareholders;  (ii) providing an attractive  compensation vehicle to attract and
retain qualified individuals employed  by the Company  and its subsidiaries  and
affiliates; and (iii) encouraging employees to invest in Common Stock. A copy of
the  SIP is annexed to this  Proxy Statement as Exhibit B  and should be read in
its entirety. The following is a brief summary of the significant provisions  of
the SIP.
 
     The  SIP,  along  with  the  other two  plans  under  consideration  by the
shareholders, comprises an integral  part of the  Company's efforts to  increase
stock  ownership by corporate  executive officers (and  other Company employees)
and align their interests with shareholders.  Under the SIP, the Committee  (see
Administration  below) is authorized  to grant any employee  of the Company, its
subsidiaries or affiliates, stock options, stock appreciation rights, restricted
stock, merit awards, performance awards, stock distributions under other Company
programs,  and  other  stock  based  awards  (collectively,  the  'Awards'),  as
described in more detail below.
 
ADMINISTRATION
 
     The  SIP is administered by  a committee comprised of  at least two or more
'outside directors' (within  the meaning  of Code Section  162(m)(4)(C)) all  of
whom  are 'non-employee directors' (within the meaning of Rule 16b-3 promulgated
under the Exchange Act). Presently, the Organization and Compensation  Committee
serves as the Committee.
 
SHARES AVAILABLE
 
     The  number of authorized and unissued shares of Common Stock available for
Awards  under  the  SIP  is  3,000,000  shares  (provided  that  only  1,000,000
authorized  and  unissued shares  may be  awarded as  Restricted Stock).  To the
extent that  shares of  Common  Stock relating  to  outstanding Awards  are  not
 
                                       31
 
<PAGE>
<PAGE>
issued  either because such  Awards are forfeited or  terminated pursuant to the
SIP, such shares of Common Stock immediately become available for Awards.
 
     The maximum number of  shares of Common  Stock that may  be awarded to  any
participant   under  the  SIP  pursuant  to  Options,  SARs,  Restricted  Stock,
Performance Awards, Merit Awards  or Other Stock Based  Awards (each as  defined
below)  is 2,000,000 shares. On March 4, 1997, the closing price of Common Stock
on the New York Stock Exchange was $30 5/8 per share.
 
ELIGIBILITY AND PARTICIPATION
 
     All employees of the Company, its subsidiaries and affiliates are  eligible
to  participate  in the  SIP.  The selection  of  which employees  will actually
receive an Award, and thereby participate in  the SIP, is made by the  Committee
in   its  complete  discretion.  As  of  March  3,  1997,  the  Company  employs
approximately 6,866 employees. There are 18 executive officers and approximately
270 key  management employees.  The decision  as  to which  Awards are  made  to
employees  in  each of  the  classifications is  made  by the  Committee  in its
complete discretion.
 
STOCK OPTIONS
 
     The Committee  is authorized  to  grant options  to purchase  Common  Stock
('Options')  under the SIP. Under the SIP, these options may be either Incentive
Stock  Options,  designed  to  achieve  favorable  federal  tax  treatment   for
participants  (under  United States  law), or  Nonqualified Stock  Options. Each
Option must be evidenced by an agreement with the participant setting forth  the
terms  of the Award.  The Option Price (i.e.,  price at which  the Option may be
exercised) may not be less than the fair market value of the Common Stock on the
date of grant. Option terms may not exceed 10 years. All other terms,  including
the  timing of exercisability, will be set forth in the agreement evidencing the
Award. The  Committee has  discretion  to accelerate  the exercisability  of  an
Option at any time.
 
     Options  may be exercised by paying the  Option Price to the Company (i) in
cash, by check, money order (or other method acceptable to the Committee) in the
currency acceptable to the Committee, (ii) through the delivery of Common  Stock
with  an aggregate fair market value on the date of exercise equal to the Option
Price for  the  shares  of Common  Stock  to  be purchased,  (iii)  through  the
withholding of Common Stock issuable upon exercise with an aggregate fair market
value  equal to the Option Price for the shares of Common Stock to be purchased,
(iv) through the  delivery of irrevocable  instructions to a  broker to  deliver
promptly  to the  Company an  amount equal  to the  Option Price  for the shares
purchased, or (v) any combination of the above methods.
 
     The Committee intends to make its first  grant under the SIP pursuant to  a
global  stock option program  under which each  employee of the  Company and its
subsidiaries (excluding  executive  officers and  other  key employees  who  are
eligible  for other  Option awards)  will be granted  an Option  to purchase 100
shares of Common Stock. It is  anticipated that this will result in  outstanding
Options  to  purchase  approximately  500,000  shares.  Because  legal  or other
considerations in  countries  outside of  the  United States  may  make  Options
impractical  or impossible, Awards other than Options  may be made under the SIP
to provide participants with a comparable Award.
 
                                       32

<PAGE>
STOCK APPRECIATION RIGHTS
 
     The Committee is  authorized to  grant stock  appreciation rights  ('SARs')
which provide participants with an amount payable in either cash or Common Stock
equal to the excess of the price of Common Stock on the date of exercise and the
fair market value on the date of grant (the 'Spread').
 
     The  SIP also  provides for  the grant  of limited  SARs which  provide the
holders with a distribution payable in cash equal to the excess of the change in
control price on the date of exercise over  the price on the date of grant.  If,
prior  to a complete takeover (i.e., acquisition of 100% of Common Stock), there
is a subsequent change in control in which the Company's shareholders receive an
additional amount  in respect  of the  change in  control, individuals  who  had
exercised their limited SARs receive this additional amount as well.
 
     SARs  may be  granted in  conjunction with an  Option or  independent of an
Option. If granted in conjunction with  an Option, a participant would have  the
choice  of either  exercising the  Option (to  receive the  underlying stock) or
exercising the SAR (to receive the Spread).  The exercise price of SARs may  not
be less than the fair market value of the Common Stock on the date of grant. The
term of an SAR may not exceed 10 years. All other terms, including the timing of
exercisability,  will be  set forth in  the agreement evidencing  the Award. The
Committee has discretion to accelerate the exercisability of an SAR at any time.
 
RESTRICTED STOCK
 
     The Committee is authorized to grant employees stock which is subject to  a
substantial risk of forfeiture ('Restricted Stock'). As a condition to the grant
of Restricted Stock, the Committee may require an employee to pay the Company an
amount  equal to,  or in excess  of, the par  value of the  shares of Restricted
Stock awarded. Restrictions on  Restricted Stock will  lapse in accordance  with
the  terms specified by the Committee  in its complete discretion. The Committee
has the discretion to  accelerate the date on  which restrictions on  Restricted
Stock  lapse at any  time. Each Restricted  Stock Award must  be evidenced by an
agreement with the participant holder setting forth the terms of the Award.
 
     The SIP limits  the number of  authorized but unissued  shares that may  be
used   for  Restricted  Stock  Awards  to  1,000,000  shares.  As  described  in
'Transactions with Management' on page 19 of this Proxy Statement, the Committee
has set Stock Ownership Guidelines for executive officers which they must attain
within five years. To assist the executive officers in meeting these guidelines,
the Company has established  an executive loan program.  However, to provide  an
incentive  for  executive  officers  to commit  their  resources  up  front, the
Committee also established  an enhanced stock  acquisition program, under  which
executive  officers are awarded one share  of Restricted Stock (the restrictions
of which lapse after three years) for  each two shares of Common Stock that  the
executive  officer purchases with  his or her  own resources. At  this time, the
Company intends  to purchase  in the  open  market all  shares of  Common  Stock
required  to be issued as Restricted Stock under the SIP, but reserves the right
to issue Restricted Stock under the SIP. Restricted Stock Awards made under  the
SIP  pursuant to this  enhanced stock acquisition  program would be  made on the
first day of the  month following presentation of  evidence satisfactory to  the
Committee that the requirements to receive such an Award are satisfied.
 
MERIT AWARDS
 
     The Committee is authorized to make an Award of Common Stock to individuals
who,  in the Committee's  discretion, merit such  Awards. As a  condition to the
grant of a Merit Award, the
 
                                       33
 
<PAGE>
<PAGE>
Committee may require an employee to pay  the Company an amount equal to, or  in
excess  of,  the  par  value  of  the shares  of  Common  Stock  awarded.  It is
anticipated that Merit Awards will initially be used in lieu of cash bonuses for
awards in recognition  of specific achievements  (such as the  Scientist of  the
Year  Award) as well as to award  teams that successfully achieve specific goals
(e.g., asset consolidation goals).
 
PERFORMANCE AWARDS
 
     The Committee is authorized to grant  Awards under the SIP that qualify  as
Performance  Awards. Performance Awards may be Restricted Stock, Merit Awards or
Other Stock Based Awards,  except that the receipt  or vesting of a  Performance
Award is based upon the attainment of performance goals that are established for
a performance period. Performance goals are established using one or more of the
performance measurements set forth in Appendix A to Exhibit B.
 
     Performance  Awards may  be granted to  any employee but  are structured to
provide  Awards  to   executive  officers   that  meet   the  requirements   for
deductibility under Code Section 162(m). Because a Performance Award is intended
to  qualify as 'performance-based compensation' under Code Section 162(m)(4)(C),
the persons eligible  for the Award,  the applicable performance  goals and  the
circumstances  under  which an  Award is  granted or  vests must  be established
during the first 90 days (or if  shorter, the first quarter) of the  performance
period.  In accordance with the requirements of Code Section 162(m), Performance
Awards may only  be modified to  reduce or eliminate  Performance Awards and  no
Awards  may be granted  or vested (as applicable)  until the Committee certifies
that the performance goals supporting the Award have been satisfied.
 
STOCK DISTRIBUTIONS UNDER OTHER COMPANY PROGRAMS
 
     From time to time, the Company may establish plans and programs under which
compensation is payable to executive officers  and key employees. To the  extent
these  programs  provide for  a  distribution to  be  made in  Common  Stock the
Committee may,  in its  discretion,  treat these  distributions as  having  been
awarded under the SIP.
 
OTHER STOCK BASED AWARDS
 
     The Committee is authorized to grant awards under the SIP that are based on
Common  Stock  but are  not Options,  SARs, Restricted  Stock, Merit  Awards, or
Performance Awards.  It is  anticipated that  Other Stock  Based Awards  may  be
necessary  in connection  with grants to  employees based outside  of the United
States where  local  law  or  other  considerations  make  it  impracticable  or
impossible  to grant one of  the other Awards under the  SIP. For example, if it
were not possible to grant  an employee a Merit  Award, the Company might  elect
instead  to grant  an Other Stock  Based Award  with an equivalent  value to the
Merit Award that would have otherwise been provided.
 
CHANGE IN CONTROL
 
     The SIP does not specifically require  any action upon a change in  control
but  provides  the  Committee  with  the  flexibility  to  provide  that  Awards
accelerate or become vested upon a change in control. This determination may  be
made  either at  the time the  Award is  granted or thereafter.  In addition, as
noted in  the discussion  of SARs,  the  Committee has  the authority  to  grant
limited  SARs which would provide the holders with the right to receive an Award
related to the price paid for
 
                                       34
 
<PAGE>
<PAGE>
Common Stock in  a change in  control. See 'Stock  Appreciation Rights' of  this
Proposal 4 at page 33 of this Proxy Statement.
 
     The  Committee  intends to  provide that  Options  granted pursuant  to the
global stock  option  program will  accelerate  upon  a change  in  control.  In
addition, the Committee intends to provide that restrictions on Restricted Stock
awarded  to participants in connection with the Stock Ownership Guidelines would
lapse on a change in control. See 'Restricted Stock' of this Proposal 4 at  page
33 of this Proxy Statement.
 
EFFECT OF EMPLOYMENT TERMINATION
 
     Generally,  and  unless  the  agreement under  which  an  Award  is granted
provides otherwise, upon  termination of  employment (other than  for cause  (as
defined  in the SIP)), (i) each Option, SAR  and Other Stock Based Award that is
exercisable at the time  of employment termination  will remain exercisable  for
three  months after employment termination, (ii)  each share of Restricted Stock
(and each Other  Stock Based Award  that is subject  to restrictions) for  which
restrictions  have not  lapsed shall be  forfeited and canceled,  and (iii) each
Performance Award (and each Other Stock Based Award that requires attainment  of
certain  performance  goals),  the award  or  vesting  of which  depends  on the
performance of the Company and/or  its subsidiaries during a performance  period
that  has not  ended on  the date employment  terminates, will  be forfeited and
canceled.
 
     Exceptions to this  rule are  provided upon employment  termination due  to
death,  disability or retirement for Options,  SARs and Other Stock Based Awards
that are  exercisable at  the  time employment  terminates and  for  Performance
Awards.  Options, SARs  and Other  Stock Based Awards  may be  exercised for the
three year period (or if shorter until their term expires) following termination
of employment  for  death, disability,  or  retirement. Payment  of  Performance
Awards  will be made to the participant (or  to his or her estate) on a pro-rata
basis (based  on  the  number  of  full and  partial  months  during  which  the
participant  participated  during  the performance  period)  at the  end  of the
performance period.
 
AMENDMENT AND TERMINATION
 
     The SIP may be amended or terminated by the Board of Directors at any  time
but  generally  an amendment  may  not, without  the  consent of  a participant,
adversely affect or  impair a  right available under  an Award.  Notwithstanding
this  provision, the Committee  may provide for  the forfeiture of  Awards if it
determines, in  its  complete discretion,  that  a participant  has  engaged  in
activity  which is contrary to the interests of the Company, its subsidiaries or
affiliates. No amendments may be made  to increase the number of authorized  but
unissued shares available for Award without shareholder approval or to make such
other  changes for which shareholder approval  is required under Sections 162(m)
or 422 of the Code.
 
CURRENT DETERMINATION OF AWARDS
 
     The Committee has made no determination with respect to grants of  Options,
SARs,  Restricted Stock, Merit Awards, Performance  Awards, or Other Stock Based
Awards under  the  SIP.  Further  since such  grants  are  entirely  within  the
discretion  of  the Committee,  it is  not  possible to  determine the  types or
amounts of Awards that would have been granted  for 1996 if the SIP had been  in

U.S. FEDERAL TAX ISSUES
 
     The  following is  a brief  description of  the tax  consequences of Awards
under the SIP based on U.S. federal tax laws current in effect.
 
Options
 
     There are no U.S. federal tax  consequences either to the Option holder  or
to  the Company upon the  grant of an Option. Upon  the exercise of an Incentive
Stock Option, the Option  holder will not recognize  any income and the  Company
will  not be entitled  to a deduction,  although such exercise  may give rise to
alternative  minimum  tax  liability  to  the  participant.  Generally,  if  the
participant  disposes of shares acquired upon the exercise of an Incentive Stock
Option within two years  after the date  of grant or within  one year after  the
date  of exercise, the amount  realized will be treated  as ordinary income, and
the Company will be  entitled to a  deduction, equal to the  excess of the  fair
market  value  of the  shares  on the  date of  exercise  over the  Option Price
(limited generally to  the gain  on the  sale). Upon  the ultimate  sale of  the
shares,  the balance of  any gain or loss  will be treated as  a capital gain or
loss to the participant. If the  participant holds the shares acquired upon  the
exercise of the Incentive Stock Option for more than two years after the date of
grant and more than one year after the date of exercise, the Company will not be
entitled  to any deduction and the entire  gain or loss for the participant will
be treated as a capital gain or loss.
 
     Upon the exercise of  a Nonqualified Stock Option,  the excess of the  fair
market  value of the Common Stock acquired  over the Option Price will generally
be taxable  to  the Option  holder  as ordinary  income  and deductible  by  the
Company. The disposition of shares of Common Stock acquired upon the exercise of
a  Nonqualified Stock Option will generally result in a capital gain or loss for
the participant, but will have no tax consequences for the Company.
 
SARs
 
     The amount of  any cash  (or the  fair market  value of  any Common  Stock)
received  by the holder of SARs under the SIP will be treated as ordinary income
in the year of receipt and the Company will be entitled to a deduction for  such
amount.
 
Restricted Stock
 
     A participant awarded Restricted Stock will not recognize taxable income at
the  time  of  the  Award  unless  he  or  she  elects  otherwise.  At  the time
restrictions on  the  Restricted Stock  lapse,  the participant  will  recognize
ordinary  income and the  Company will be entitled  to a corresponding deduction
equal to the excess of the fair market value of the Common Stock on the date the
restrictions lapse over the amount, if  any, paid for such stock. Dividends,  if
any,  paid to the  participant on Restricted  Stock will be  taxable as ordinary
income and deductible by the Company.
 
                                       36
 
<PAGE>
<PAGE>
Merit Awards
 
     A grant of Common Stock  pursuant to a Merit Award  will be taxable to  the
participant  as  ordinary income  and  the Company  will  be entitled  to  a tax
deduction equal to  the fair market  value of the  Common Stock on  the date  of
grant less any amount paid for such stock.
 
Stock Distributions Under Other Company Programs
 
     Common  Stock distributed in lieu of cash under other Company programs will
be taxable  to  the participant  as  ordinary income  and  the Company  will  be
entitled  to a tax deduction equal to the  fair market value of the Common Stock
on the date of distribution.
 
Performance Awards and Other Stock Based Awards
 
     The taxability  of Performance  Awards and  Other Stock  Based Awards  will
depend on the form of these Awards.
 
Effect of Code Section 162(m) on Deductibility
 
     Code  Section 162(m) limits  the deductibility of  compensation paid to the
Chief Executive Officer and the four  other most highly compensated officers  to
$1,000,000.  Not counted  for purposes of  the $1,000,000  limit is compensation
that qualifies as  'performance-based compensation' within  the meaning of  Code
Section  162(m)(4)(C).  Generally  Options  and  SARs,  and  Performance  Awards
specifically designed to  qualify under  Code Section 162(m),  would qualify  as
performance-based  compensation. Were other amounts  payable under the SIP (when
combined with other  non-performance-based compensation)  to exceed  $1,000,000,
the excess would not be deductible by the Company.
 
Effect of Payments on a Change in Control
 
     If  amounts are payable under the SIP as a result of a change in control to
individuals who  are  officers,  shareholders or  highly  compensated  employees
(e.g.,  among the highest paid 1% of employees), all or a portion of the amounts
realized may be  characterized as  'excess parachute payments'.  If amounts  are
characterized  as excess parachute payments, the  amount of the payment (as well
as any  other amounts  that are  in excess  of the  participant's 'base  amount'
(i.e.,  one times most recent 5 year average W-2 compensation)) would be subject
to a 20%  excise tax and  would be  nondeductible to the  Company. Such  amounts
would also lower the $1,000,000 limit on deductibility.
 
     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 SIP.
 
     THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS THAT SHAREHOLDERS VOTE FOR
THIS PROPOSAL TO APPROVE THE ADOPTION OF THE SIP.
 
                                   PROPOSAL 5
                   PROPOSAL TO APPROVE THE WITCO CORPORATION
                        OFFICERS' ANNUAL INCENTIVE PLAN
 
     At  a meeting held on March 4,  1997, the Board of Directors terminated the
Original OAIP  and adopted,  subject to  shareholder approval,  a revised  Witco
Corporation  Officers' Annual Incentive  Plan (the 'revised  OAIP'). The revised
OAIP  is  designed   to  promote   the  interests   of  the   Company  and   its
 
                                       37

shareholders  by  providing  (i)  selected  officers  of  the  Company  and  its
subsidiaries an  incentive  to contribute  to  the Company's  profitability  and
performance  by providing the officers with the opportunity to receive an annual
bonus; (ii) an attractive compensation  vehicle to attract, motivate and  retain
qualified  individuals in  the employ of  the Company and  its subsidiaries; and
(iii) a program under  which officers can  receive Common Stock.  A copy of  the
revised  OAIP is annexed to this Proxy Statement as Exhibit C and should be read
in its entirety. The following is a brief summary of the significant  provisions
of the revised OAIP.
 
     The revised OAIP, along with the other two plans under consideration by the
shareholders,  comprises an integral  part of the  Company's efforts to increase
stock ownership  by corporate  executive officers  (and other  employees of  the
Company and its subsidiaries) and align their interests with shareholders. Under
the  revised  OAIP, the  Committee  (see 'Administration'  below)  may determine
whether payment of the bonus will be in Common Stock or in cash. Until such time
as officers have met the Stock Ownership Guidelines, it is the intention of  the
Committee  to have at least  20% of such officer's  bonus under the revised OAIP
paid in Common Stock.
 
ADMINISTRATION
 
     The revised OAIP is administered by  a committee comprised of at least  two
or  more 'outside directors'  (within the meaning  of Code Section 162(m)(4)(C))
all of  whom are  'non-employee directors'  (within the  meaning of  Rule  16b-3
promulgated   under  the   Exchange  Act).   Presently,  the   Organization  and
Compensation Committee serves as the Committee.
 
MAXIMUM PERFORMANCE BONUS
 
     The maximum annual  performance bonus  per participant  payable under  this
plan is $2,000,000 ($3,000,000 for the Chief Executive Officer).
 
ELIGIBILITY AND PARTICIPATION
 
     Eligibility  in the  revised OAIP is  limited to executive  officers of the
Company and its subsidiaries. The  decision of which employees will  participate
in  the revised OAIP and receive the opportunity to earn a performance bonus for
any particular  bonus  period  shall  be  made by  the  Committee  in  its  sole
discretion. There are 18 executive officers.
 
PERFORMANCE BONUSES
 
     The  revised OAIP provides for the  payment of performance bonuses upon the
achievement of  a target  based on  one  or more  of the  objective  performance
measurements listed in Appendix A to Exhibit C.
 
Establishing the Target
 
     During  the first 90  days in the  bonus period (or,  in the case  of a new
hire, within the first quarter of  such individual's participation in the  bonus
period),  the Committee will determine (i)  the performance measurements and the
targeted level of performance (the 'OAIP Target'), (ii) the percentage of salary
to be paid  upon attaining  the OAIP Target,  (iii) the  range of  'performance'
percentages  to be paid upon  achievement of various levels  of the OAIP Target,
and (iv) the amount of any adjustment factor and the performance measurements on
which the adjustment will be made.
 
                                       38
 
<PAGE>
<PAGE>
Determination of the Performance Bonus
 
     No later than 90 days following the  end of each bonus period, the  Company
will calculate the performance measurements for the bonus period to determine if
the OAIP Target has been achieved. Once the Committee certifies the results, the
performance  bonus  payable,  if  any, will  be  determined  by  multiplying the
participant's base salary for  the bonus period by  the targeted percentage  and
then  multiplying  that  result  by the  applicable  performance  percentage (to
reflect the  actual level  of performance).  If an  adjustment factor  has  been
established  for the bonus  period, the performance bonus  will then be adjusted
appropriately.
 
Payment of the Performance Bonus
 
     The performance bonus may be paid  in cash, Common Stock, or a  combination
of  both in the complete discretion of the Committee. For executive officers who
have not  met  the  Stock Ownership  Guidelines,  it  is the  intention  of  the
Committee  to have at least  20% of such officer's  bonus under the revised OAIP
paid in  Common Stock.  No shares  have  been reserved  for issuance  under  the
revised  OAIP. At this time, the Company  intends to purchase in the open market
all shares of Common  Stock required to be  distributed under the revised  OAIP,
but  reserves the  right to  issue such  shares under  the SIP  if such  plan is
approved  by  the  Company's  shareholders   at  the  1997  Annual  Meeting   of
Shareholders.
 
EFFECT OF TERMINATION OF EMPLOYMENT; CHANGES MID-BONUS PERIOD
 
     Except as set forth below, no participant will be entitled to a performance
bonus with respect to a bonus period unless he or she is employed by the Company
on  the  last day  of  such bonus  period. In  the  event of  death, disability,
retirement, termination of employment  without cause or  transfer to a  position
that  is not eligible for benefits under the revised OAIP during a bonus period,
the participant (or,  if applicable,  the participant's estate)  will receive  a
pro-rated  performance bonus based on  the number of full  and partial months in
the bonus period that the participant was covered by the revised OAIP.
 
     The revised OAIP also contains  provisions addressing the possibility  that
during  a bonus  period, a  participant will be  transferred to  a position with
different  performance  criteria,   performance  measurement(s),  OAIP   Target,
targeted percentage, performance percentage range, and adjustment factor. In the
event  of such  a transfer,  the bonus  period is  bifurcated and  the criteria,
percentages and adjustment  factor applicable  to such new  position will  apply
after  such  transfer  (with  the amount  of  the  performance  bonus determined
pro-rata for each portion of the bonus period based on the applicable criteria),
unless the Committee determines that (i)  the participant shall not be  eligible
for  the  remainder  of  the  bonus  period  (in  which  case  the participant's
performance bonus will be  determined on a  pro-rata basis based  on his or  her
performance  prior  to  the  date  of  transfer),  or  (ii)  attainment  of  the
performance targets applicable to the new position are substantially certain (in
which case  the bonus  period  will not  be  bifurcated, and  the  participant's
performance  bonus for the remainder of the bonus period shall be based entirely
on the  criteria  applicable  to  the former  position).  If  a  participant  is
transferred  to a new position for  which no performance criteria or percentages
have been previously established, the participant will continue to be covered by
the criteria  applicable to  his or  her  former position  unless prior  to  the
expiration  of  25%  of the  portion  of  the bonus  period  which  follows such
transfer, the Committee  establishes new performance  criteria, percentages  and
adjustment factor which shall apply to the participant for the remainder of such
bonus period.
 
                                       39
 
<PAGE>
<PAGE>
AMENDMENT AND TERMINATION
 
     The  Committee may at any  time amend the revised  OAIP with respect to any
bonus period which has not yet commenced. However, no amendment may be made  for
which  shareholder  approval  would be  required  for the  performance  bonus to
qualify as 'performance-based compensation' within  the meaning of Code  Section
162(m)(4)(C), unless such approval has been obtained.
 
     The  Committee  may at  any  time terminate  or  suspend the  revised OAIP.
However, if the Committee terminates or  suspends the revised OAIP more than  90
days after the commencement of a bonus period, each participant shall receive at
the end of such bonus period the greater of: (i) the performance bonus he or she
would  have received had such termination  or suspension not been effected based
on actual performance, and (ii) the performance  bonus 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 revised  OAIP all  rights of a
participant with respect to any bonus period  that has not ended on or prior  to
the date of such termination shall become null and void.
 
CURRENT DETERMINATION OF AWARDS
 
     On March 4, 1997, the Committee established as the OAIP Target for the 1997
bonus period the attainment of earnings per share of $1.50 ('EPS') and operating
cash  flow of  $240 million ('Cash  Flow'), which  performance measurements were
weighted 75% and 25% respectively. No adjustment factor has been established for
the 1997 bonus period.
 
     The percentage of the target bonus  attributable to EPS ranges from 50%  of
the  target bonus (for  attainment of 80% of  the target) to  250% of the target
bonus (for attainment  of 140% of  the target). The  percentage of target  bonus
attributable to Cash Flow ranges from 50% of the target bonus (for attainment of
87%  of the target) to 250%  of the target bonus (for  attainment of 126% of the
target). The payout  for performance  within this  range will  be determined  by
interpolating  from these  percentages. There is  no payout with  respect to the
performance measurements  of  EPS  and  Cash  Flow if  less  than  80%  or  87%,
respectively,  of  the  target for  such  measurement is  achieved.  Because two
performance measurements  will be  used  for the  1997  bonus period,  the  1997
performance  bonus  will  be  determined  by  calculating  the  payout  for each
measurement separately  and  then  multiplying  the  performance  bonus  by  the
appropriate weighted factor (i.e., 75% or 25% as applicable).

U.S. FEDERAL TAX ISSUES
 
     Performance bonuses payable under the revised OAIP (whether paid in cash or
distributed  as Common Stock) will  be taxed as ordinary  income and the Company
will be  entitled  to a  deduction  in the  amount  received when  paid  to  the
participant.
 
     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 revised OAIP.
 
     THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS THAT SHAREHOLDERS VOTE FOR
THIS PROPOSAL TO APPROVE THE ADOPTION OF THE REVISED OAIP.
 
                             ADDITIONAL INFORMATION
 
     The  entire  cost  of  this  solicitation will  be  borne  by  the Company,
including reimbursement  of banks,  brokerage  firms, custodians,  nominees  and
fiduciaries  for their  reasonable expenses  in sending  proxy materials  to the
beneficial owners of  stock. Proxies may  be solicited personally,  by mail,  by
telephone,  by facsimile  or by telegraph,  by the directors,  officers or other
employees of the Company, without remuneration other than regular  compensation.
In  addition, the Company has retained Georgeson & Company Inc. to assist in the
solicitation  of  proxies  at   a  fee  estimated   to  be  $10,500,   excluding
out-of-pocket expenses.
 
     At the date of this Proxy Statement, management does not know of any matter
to  be brought before the meeting for action other than the matters described in
the Notice of Annual Meeting and matters incident thereto. If any other  matters
should  properly come before the  meeting, the holders of  the proxies will vote
and act with  respect to such  matters in accordance  with their best  judgment.
Discretionary  authority  to  do  so  is conferred  by  the  enclosed  proxy. In
connection with the 1997  Annual Meeting of Shareholders,  the General Board  of
Pension and Health Benefits of the United Methodist Church, the beneficial owner
of  181,400 shares of Common Stock,  submitted a shareholder proposal requesting
diversity on the Board of Directors and requesting the Company to issue a policy
statement and  report on  the topic.  The proponents  agreed to  withdraw  their
proposal  based upon the Company's representation that it will state at its 1997
Annual Meeting of Shareholders its commitment that the Company's management  and
Board  of  Directors  should  reflect  the  workforce,  customer,  supplier  and
 
                                       41

community diversity affecting  the Company's activities.  Further, the  Company,
with  the  assistance of  professional search  advisors,  has identified  and is
interviewing qualified  women  and  minority candidates  for  inclusion  on  the
Company's Board to fill existing vacancies.
 
     The  proxy is revocable  by a shareholder  at any time  before the exercise
thereof, and the giving of such proxy will not affect the shareholder's right to
vote in person if it is later found to be convenient to attend the meeting.
 
     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 1998, 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 21, 1997. 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 business the
shareholder proposes to bring before the annual meeting (i) a brief  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 amend either  the
certificate  of incorporation of the Company or the by-laws, the language of the
proposed amendment, (ii) the name and address of the shareholder proposing  such
item  of business, (iii)  a representation that  the shareholder is  a holder of
record of stock of the Company entitled to vote at such meeting having a  market
value  of at least  one thousand dollars and  intends to appear  in person or by
proxy at the meeting  to propose such  item of business,  and (iv) any  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.
 
     Please  fill in, sign and date the enclosed  form of proxy and return it in
the accompanying self-addressed  envelope which requires  no further postage  if
mailed  in the United States.  If you attend the  Annual Meeting of Shareholders
and wish to  vote your  shares in  person, you may  do so.  Your cooperation  in
giving this matter your prompt attention will be appreciated.

SECTION 2. PURPOSE
 
     The purpose of this Witco  Corporation Shareholder Value Incentive Plan  is
to  promote the interests of Witco Corporation and its shareholders by providing
selected officers and employees of  Witco Corporation and its subsidiaries  (the
'Company')  with  a strong  incentive to  increase dramatically  the shareholder

performance of  duties with  the Company;  (B) the  failure (other  than due  to
Disability)  to substantially perform  the duties of one's  job; (C) engaging in

SECTION 7. ELIGIBILITY
 
     Stock  Grants  shall  only be  made  to  Eligible Employees  who  have been
employed with the Company for at least six consecutive months. The selection  of
which  Eligible Employees  shall be issued  a Stock  Grant shall be  made by the
Committee in its complete discretion.
 
SECTION 8. STOCK GRANTS
 
     (a) Stock Grants. The Committee may grant Convertible Preferred Stock under
this Plan at any time prior to the  date the Target is achieved, except that  no
such grants may be made at a time when achievement of the Target, in the opinion
of  the Committee, is substantially  certain. Convertible Preferred Stock issued
pursuant to  this Plan  shall be  restricted as  to Transfer  and subject  to  a
substantial risk of forfeiture as provided in this Plan.
 
     (b)  Written Subscription Agreement. Each Stock Grant shall be evidenced by
a written subscription  agreement setting forth  the terms of  ownership of  the
Convertible  Preferred Stock  that are consistent  with this  Plan and providing
that if the Participant shall resign from employment after the Target shall have
been  achieved,  for  the  two-year  period  following  such  resignation,   the
Participant shall not, without the prior written consent of Witco:
 
          (i) render services of any nature for compensation to any person, firm
     or  corporation, nor shall  the Participant acquire  any financial interest
     (except for stock interests  in publicly-held companies  which will not  be
     significant  and in  any event  will not  exceed five  percent (5%)  of the
     outstanding stock of any such company) in any business that is engaged in a
     business engaged in by the Company in any substantial manner on or prior to
     the date the Participant's employment terminates; or
 
          (ii) solicit  any employee  of the  Company to  terminate his  or  her
     employment.
 
In  addition, the Participant  shall be bound  not to disclose,  divulge or make
accessible to any third party any information of a secret or confidential nature
which became known to  the Participant in  the course of  his or her  employment
with  the Company until such information has  come into the public domain or has
otherwise ceased to be secret or confidential.
 
     (c) Restrictions. Each share of  Convertible Preferred Stock granted  shall
be  subject to restrictions on Transfer  except that the following Transfers, if
permitted by the  subscription agreement under  which the Stock  Grant is  made,
shall be permitted:
 
          (i) a Transfer made to the Company (or its assignee);
 
          (ii)  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, corporation or partnership,  the
     beneficiaries,  stock  holders  or  partners,  respectively  of  which  are
     comprised solely of the Participant's immediate family (any such individual
     or entity a 'Permitted Transferee'); and
 
          (iii) a Transfer from a Permitted Transferee back to the Participant;
 
    provided, however, that  a Transfer pursuant  to this Section  shall not  be
    given effect on the books of Witco unless and until the transferee agrees in
    writing,  in form and substance satisfactory  to the Committee, to be become
    bound by the terms of the Plan.

     (d) Lapse  of Restrictions.  Restrictions on  Transfer of  the  Convertible
Preferred  Stock shall lapse on the date the Committee certifies in writing that
the Target has been achieved or as provided in Section 10.
 
     (e) Legend. Each certificate of  Convertible Preferred Stock granted  under
this  Plan  shall be  registered  in the  name of  the  Participant to  whom the
Convertible Preferred Stock was granted  (or a Permitted Transferee),  deposited
with Witco together with a stock power endorsed in blank, and bear the following
or a substantially similar legend:
 
     THE  SECURITIES REPRESENTED  BY THIS  CERTIFICATE MAY  NOT BE  GIVEN, SOLD,
     ASSIGNED, TRANSFERRED, PLEDGED  OR OTHERWISE  DISPOSED OF  (WHETHER FOR  OR
     WITHOUT   CONSIDERATION,  AND  WHETHER  VOLUNTARILY,  INVOLUNTARILY  OR  BY
     OPERATION OF LAW) UNLESS  SUCH GIFT, SALE,  ASSIGNMENT, TRANSFER, OR  OTHER
     DISPOSITION COMPLIES WITH THE WITCO CORPORATION SHAREHOLDER VALUE INCENTIVE
     PLAN  AND THE SUBSCRIPTION AGREEMENT UNDER WHICH THE SECURITIES WERE ISSUED
     TO THE PARTICIPANT.
 
     THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE NOT REGISTERED UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE  OR
     ANY OTHER JURISDICTION.
 
SECTION 9. EFFECT OF EMPLOYMENT TERMINATION ON STOCK GRANTS
 
     (a)  General Rule.  Except as  otherwise provided in  this Section  9, if a
Participant's employment terminates for  any reason prior to  the date that  the
Target is achieved, all shares of Convertible Preferred Stock (whether held by a
Participant  or  Permitted Transferee)  shall  be forfeited  and  Transferred to
Witco.
 
     (b)  Certain  Employment  Terminations.  If,   within  one  year  after   a
Participant's  employment  terminates  because  of  the  Participant's  death or
Disability, the  Target  is  achieved or  there  is  a Change  in  Control,  the
Participant shall receive a pro-rated distribution from this Plan equal in value
to  the Common  Stock the  Participant would  have received  had he  or she been
employed on the date  the Committee certified that  the Target is achieved.  The
pro-rated  distribution shall  be determined  by multiplying  the value  of such
distribution by a fraction, the numerator of  which shall be the number of  full
and  partial months  elapsed from the  date of the  Stock Grant to  the date the
Participant's employment terminated, and the  denominator of which shall be  the
number  of full and partial  months elapsed from the date  of the Stock Grant to
the date the Committee certifies the Target is achieved. Such distribution shall
be paid in Common Stock or in cash equal to the preceding date of  distribution,
in the Committee's complete discretion.
 
SECTION 10. MANDATORY FORFEITURE; CHANGE IN CONTROL
 
     (a)  Mandatory  Forfeitures. If  the Target  is not  achieved by  the fifth
anniversary of  the Effective  Date  of this  Plan,  all shares  of  Convertible
Preferred Stock shall be forfeited and Transferred to Witco and the Participants
(or,  if applicable, their  Permitted Transferees) shall  have no further rights
under the Plan.
 
     (b) Change in Control. Each subscription agreement evidencing a Stock Grant
under this Plan  shall provide that  in the event  of a Change  in Control,  the
restrictions  on all shares  of Convertible Preferred Stock  shall lapse and, in
accordance with the terms of the Convertible Preferred Stock, such shares  shall
 
                                      A-5
 
<PAGE>
<PAGE>
automatically  convert  into the  applicable number  of  shares of  Common Stock
unless a cash payment is elected in the event of an Offer pursuant to  paragraph
7  of the Certificate of Designations attached  as Appendix A. If the price paid
in the  Change in  Control (hereafter,  the 'Change  in Control  Price') is  not
greater  than $55 5/8 and at least $10  greater than the Stock Price on the date
of grant,  then  the  Participant  shall, coincident  with  the  lapse  of  such
restrictions  and the conversion of the Convertible Preferred Stock, forfeit the
shares of Common Stock into which  the Convertible Preferred Stock is  converted
and  Transfer such  shares of Common  Stock to  Witco. If the  Change in Control
Price is greater than $55 5/8 (and at least $10 greater than the Stock Price  on
the  date of grant) but less  than $75 5/8, then the  number of shares of Common
Stock to be forfeited and Transferred to  the Company shall be 5% of the  shares
of Common Stock for each whole dollar that $75 5/8 exceeds the Change in Control
Price.  For purposes of this Section 10(b), if the consideration paid for Common
Stock in a Change  in Control includes  amounts other than  cash, the Change  in
Control Price shall be determined by valuing at fair market value (as determined
by  the  Board, whose  determination  shall be  conclusive)  the stock  or other
property provided  as consideration.  Each subscription  agreement evidencing  a
Stock  Grant will provide that if, following  a Change of Control, either of the
Targets is achieved  in the same  year as that  in which the  Change of  Control
occurred,  the Company shall pay, within 90 days following the end of such year,
to any holder of Convertible Preferred Stock immediately prior to the Change  of
Control  an amount  of cash  equal to  the difference,  if any,  between (A) the
product of (i)  the Change of  Control Price  multiplied by (ii)  the number  of
shares  of Common  Stock, if  any, received by  such holder  as a  result of the
Change of Control, and (B) the product of (i) ten times the number of shares  of
Convertible  Preferred Stock  owned immediately prior  to the  Change of Control
multiplied by (ii) the Change of Control Price.
 
SECTION 11. AMENDMENT, TERMINATION, TERM
 
     (a) Amendment; Termination. The Board may at any time terminate the Plan or
make such  amendments  thereto  as it  shall  deem  advisable and  in  the  best
interests  of  the Company;  provided, however,  that  no such  amendment shall,
without the consent of the  individual to whom any  Stock Grant shall have  been
granted,  adversely affect  or impair the  rights of such  individual under such
Stock Grant, and provided, further, that unless the shareholders of Witco  shall
have first approved thereof, no amendment of the Plan shall be effective if such
amendment  would  change  the  Target (except  as  provided  in  Section 12(c)),
increase the  number of  shares of  Convertible Preferred  Stock that  could  be
granted  under the Plan or  for which shareholder approval  is required in order
for  amounts  realized  under  this   Plan  to  qualify  as   'performance-based
compensation'  under Code Section 162(m)(4)(C). Notwithstanding anything in this
Section to  the  contrary, the  Committee  may  provide for  the  forfeiture  of
Convertible  Preferred  Stock  and the  transfer  to Witco  of  such Convertible
Preferred Stock if it determines, in its complete discretion, that a Participant
has engaged in activity that is contrary to the interests of the Company.
 
     (b) Term. No Stock  Grants shall be  made under this Plan  on or after  the
fifth anniversary of the Effective Date.
 
SECTION 12. MISCELLANEOUS
 
     (a) Continued Employment/Participation Not Guaranteed. Nothing contained in
this  Plan shall confer upon  any Participant or Eligible  Employee the right to
continuation of his or  her employment with the  Company (or interfere with  the
Company's right to terminate such employment). Nothing
 
                                      A-6
 
<PAGE>
<PAGE>
contained  in this Plan  shall confer upon any  Participant or Eligible Employee
the right to receive a Stock Grant under this Plan.
 
     (b) Withholding. Applicable law may  require the withholding of taxes  from
the income or gains resulting from the Stock Grants or the subsequent conversion
and  lapsing of restrictions of shares of Convertible Preferred Stock subject to
such grants. The Company may, in its discretion, require a Participant to pay to
the Company the amount to be withheld, or make other arrangements at the time of
delivery or exercise or thereafter. To the extent permitted by the Committee,  a
Participant  may elect to  discharge his or  her withholding obligations through
(i) the payment of cash or authorization of the Company to withhold cash that is
otherwise payable to the  Participant, (ii) delivery of  shares of Common  Stock
having  a fair  market value equal  to the amount  to be withheld,  or (iii) any
combination of the above.
 
     (c) Certain  Adjustments. Appropriate  adjustments to  the Target  and  the
number  of shares of Common Stock into which the Convertible Preferred Stock may
convert  shall  be  made  upon   any  stock  dividends,  splits,   combinations,
recapitalizations  or other  adjustment in the  number of  outstanding shares of
Common Stock as provided in the  Certificate of Designations attached hereto  as
Appendix A.
 
     (d)  Funding; Expenses. This Plan shall  be unfunded. Shares of Convertible
Preferred Stock (and other amounts  payable hereunder) shall be furnished  using
the  general assets  of the  Company (or  a trust  or trusts  established by the
Company to meet  its obligations  hereunder which shall  not be  subject to  the
claims of Participants) 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. All  of the expenses of the  Plan shall be borne by
the Company.
 
     (e) Governing Law; Interpretation. This Plan shall be governed by the  laws
of  the State of Delaware to the extent  not preempted by Federal law. This Plan
is intended to be administered with respect to persons covered by Section 16  of
the  Exchange  Act in  accordance with  Rule 16b-3  and the  rights of  all such
individuals shall be  construed in  accordance with such  provision. Awards  are
intended to be treated as 'performance-based compensation' within the meaning of
Code Section 162(m)(4)(C), and all rights of the Participants shall be construed
in accordance with such provision.

     Board of Directors hereby creates a series of Preferred Stock, no par value

        liquidation, dissolution or winding up of the Company within the meaning
        of this paragraph 3.
 
             4. Retirement of Shares.
 
             (a) On or before March 4, 2002, shares of Series B Preferred  Stock
        which  have been canceled as provided herein or reacquired in any manner
        by the Company shall have the status of authorized and issued shares  of
        Series B Preferred Stock, which may be reissued by the Company.
 
             (b)  On or after March 5,  2002 (the 'Retirement Date'), any shares
        of Series B Preferred Stock which have been issued, and not converted as
        provided in paragraph 6 below, shall be deemed canceled and such  shares
        shall  be  retired  and not  reissued  and  shall resume  the  status of
        authorized but unissued and non-designated shares of Preferred Stock  of
        the Company.
 
             5.  Voting. Except as required by law  and except for any voting by
        the holders of Series B Preferred Stock  as part of a separate class  or
        series  pursuant  to  any  provision  of  the  Restated  Certificate  of
        Incorporation of the Company, outstanding  shares of Series B  Preferred
        Stock shall not be entitled to vote on any matter submitted to a vote of
        shareholders.
 
             6. Conversion.
 
             (a)  Each  share of  Series B  Preferred Stock  that is  issued and
        outstanding and has not been canceled pursuant to paragraph 4(b),  shall
        automatically  convert  into 10  shares of  the Company's  common stock,
        $5.00 par value  per share ('Common  Stock') and each  such share  shall
        cease  to be outstanding on the earlier  to occur of the following dates
        (the 'Conversion Date'):
 
                (i) the date a committee of the Board comprised of at least  two
           or  more  outside  directors  (within  the  meaning  of  Code Section
           162(m)(4)(C)) all of  whom are 'non-employee'  directors (within  the
           meaning  of Rule 16(b)(3)  promulgated by the  SEC) (the 'Committee')
           certifies that  either of  the following  targets (each  of which  is
           hereinafter individually referred to as a 'Target', and both of which
           are  hereinafter  collectively  referred  to  as  the  'Targets') has
           occurred: (A) the Stock Price of the Common Stock has remained at  or
           above  $75 5/8 for a period of  ten (10) consecutive Trading Days; or
           (B) the Earnings per Share of the  Company at the end of any year  is
           at least $4.50; or
 
                (ii) on the date a Change of Control has occurred.
 
             (b)  On or  after the  Conversion Date  each holder  of a  share or
        shares of  Series B  Preferred Stock  shall deliver  the certificate  or
        certificates  therefor to the principal office of any transfer agent for
        Common Stock as  directed by the  Company. The Company  shall make  such
        arrangements  as it deems  appropriate for the  issuance of certificates
        representing shares of the Common  Stock in exchange for and  contingent
        upon  surrender  of certificates  representing  the shares  of  Series B
        Preferred  Stock  accompanied  by   instruments  of  transfer  in   form
        satisfactory
 
                                      A-9

        to  the  Company  and to  any  conversion  agent, duly  executed  by the
        registered holder or his duly  authorized attorney, and transfer  taxes,
        stamps  or funds  therefor or  evidence of  payment thereof  if required
        pursuant to paragraph 6(d) hereof. The Company shall give the holders of
        the shares of Series B Preferred Stock such notice as the Company  deems
        appropriate  and upon such  surrender such holders  shall be treated for
        all purposes as the  record holder or holders  of such shares of  Common
        Stock upon the Conversion Date.
 
             (c)  No  fractional shares  of Common  Stock or  scrip representing
        fractional shares shall be issued upon conversion of shares of Series  B
        Preferred  Stock. If  more than  one share  of Series  B Preferred Stock
        shall be surrendered for conversion at one time by the same holder,  the
        number  of  full shares  of Common  Stock which  shall be  issuable upon
        conversion thereof  shall be  computed  on the  basis of  the  aggregate
        number  of shares of Series B Preferred Stock so surrendered. Instead of
        issuing any fractional shares of  Common Stock which would otherwise  be
        issuable  upon conversion of any shares of Series B Preferred Stock, the
        number of  shares of  Common Stock  issuable by  the Company  upon  such
        conversion shall be rounded to the nearest full share.
 
             (d)  The Company shall pay any  documentary, stamp or similar issue
        or transfer tax due  on the issue of  Common Stock upon the  conversion;
        provided, however, that the holder of Series B Preferred Stock shall pay
        to the Company the amount of any tax which is due (or shall establish to
        the satisfaction of the Company payment thereof) if the shares are to be
        issued in a name other than the name of such holder.
 
             (e)  The Company shall reserve and at all times shall have reserved
        out of its authorized but unissued shares of Common Stock enough  shares
        of  Common Stock to permit the conversion of the then outstanding shares
        of Series B  Preferred Stock. All  shares of Common  Stock which may  be
        issued  upon conversion of shares of  Series B Preferred Stock shall be,
        when so issued, validly issued,  fully paid and nonassessable. In  order
        that  the Company  may issue shares  of Common Stock  upon conversion of
        shares of Series B Preferred Stock, the Company shall endeavor to comply
        with all applicable Federal and state securities laws.
 
             (f) The conversion rate and each Target in effect at any time shall
        each be subject to adjustment from time to time as follows:
 
                (i) If the Company shall, at any time or from time to time while
           any of  the  Series B  Preferred  Stock  is outstanding,  (A)  pay  a
           dividend  in shares of capital stock  to holders of Common Stock, (B)
           make a distribution in shares of  capital stock to holders of  Common
           Stock,  (C) subdivide or split the outstanding shares of Common Stock
           into a greater number of shares  of Common Stock, or (D) combine  the
           outstanding shares of Common Stock into a smaller number of shares of
           Common  Stock, then,  and in  any such  case, (any  of the  cases (A)
           through (D) of  this paragraph 6(f)(i)  are hereinafter  collectively
           referred  to as the  'Stock Number Change'), the  number of shares of
           Common Stock into  which a  holder may convert  his or  her Series  B
           Preferred  Stock in effect immediately prior  to such action shall be
           adjusted so that the holder of any shares of Series B Preferred Stock
           thereafter shall be entitled to receive upon conversion the number of
           shares of Common Stock or other capital stock that such holder  would
           have  owned or  been entitled  to receive  immediately following such
           action had such  shares of  Series B Preferred  Stock been  converted
           immediately  prior  thereto.  An  adjustment  made  pursuant  to this
           paragraph
 
                                      A-10

<PAGE>
           6(f)(i)  or   paragraph  6(f)(ii)   below  shall   become   effective
           immediately after the effective date of any Stock Number Change. Such
           adjustments shall be made successively.
 
                (ii)  If the  Company shall,  at any time  or from  time to time
           while any of the Series B Preferred Stock is outstanding,  accomplish
           a  Stock Number  Change, the  Targets shall  be adjusted  so that the
           Targets shall be equal to a number determined by multiplying (A) each
           Target in effect immediately prior to the effective date of the Stock
           Number Change by  (B) a fraction  (1) the numerator  of which is  the
           number  of shares Common  Stock outstanding immediately  prior to the
           effective date of the Stock Number Change and (2) the denominator  of
           which is the number of shares of Common Stock outstanding immediately
           after the effective date of the Stock Number Change;
 
                (iii)  If the Company  shall, at any  time or from  time to time
           while any  of the  Series  B Preferred  Stock is  outstanding,  issue
           Common  Stock at a  value or price  per share which  is less than the
           average Stock Price of the Common Stock for the ten (10)  consecutive
           Trading  Days  immediately preceding  the  date of  issuance  of such
           Common Stock (hereinafter referred to  as a 'Below Market  Issuance')
           then, and in any such case, the number of shares of Common Stock into
           which  a  holder may  convert  his or  her  Series B  Preferred Stock
           immediately prior  to such  action  shall be  adjusted so  that  such
           number  shall be equal to a  number determined by multiplying (A) the
           number of shares of Common Stock  into which such shares of Series  B
           Preferred Stock was convertible immediately prior to such issuance by
           (B)  a fraction  (1) the  numerator of which  shall be  the number of
           shares of Common Stock outstanding immediately prior to such issuance
           plus the number of such additional shares of Common Stock issued  and
           (2)  the denominator of which shall be the number of shares of Common
           Stock outstanding immediately prior to such issuance plus the  number
           of  such additional shares of Common  Stock which the aggregate price
           of the issued shares  of Common Stock would  purchase at the  average
           Stock  Price of the Common Stock for the ten (10) consecutive Trading
           Days immediately preceding  the date  of the  Below Market  Issuance.
           Such  adjustment shall become effective immediately after the date of
           the Below Market Issuance;
 
                (iv) If the  Company shall,  at any time  or from  time to  time
           while  any of  the Series  B Preferred  Stock is  outstanding, make a
           Below Market Issuance, then, and in any such case, the Targets  shall
           be adjusted so that the Targets shall be equal to a number determined
           by  multiplying (A) each  Target in effect  immediately prior to such
           Below Market Issuance by  (B) a fraction (1)  the numerator of  which
           shall be the number of shares of Common Stock outstanding immediately
           prior  to such issuance plus the  number of such additional shares of
           Common Stock which the aggregate price of the issued shares of Common
           Stock would purchase at the average  Stock Price of the Common  Stock
           for  the ten (10) consecutive  Trading Days immediately preceding the
           date of the Below  Market Issuance and (2)  the denominator of  which
           shall  be number  of shares  of Common  Stock outstanding immediately
           prior to such issuance plus the  number of such additional shares  of
           Common   Stock  issued.   Such  adjustment   shall  become  effective
           immediately after the date of the Below Market Issuance;
 
                (v) If, at any time or from time to time while any of the Series
           B Preferred Stock is outstanding,  any of the following shall  occur,
           namely:  (A) any reclassification or  change of outstanding shares of
           Common  Stock  issuable  upon  conversion  of  shares  of  Series   B
 
                                      A-11

           Preferred  Stock (other than a change in par value, or from par value
           to no par value, or from no par value to par value, or as a result of
           a subdivision or combination), or (B) any consolidation or merger  to
           which  the Company is  a party that  does not constitute  a Change of
           Control,  then  the   Company,  or  such   successor  or   purchasing
           corporation,  as the case may be,  shall, as a condition precedent to
           such reclassification, change,  consolidation or  merger, provide  in
           its  certificate of incorporation or  other charter document (1) that
           each share  of Series  B Preferred  Stock then  outstanding shall  be
           convertible  immediately  after such  transaction  into the  kind and
           amount  of  securities,  cash  or  other  property  receivable   upon
           consummation  of such transaction by a holder of the number of shares
           of Common Stock into  which such shares of  Series B Preferred  Stock
           would  have been  converted if  the Conversion  Date were immediately
           prior to consummation of such reclassification, change, consolidation
           or merger and (2) that the Targets shall be appropriately adjusted to
           be as  nearly  equal  as possible  following  such  reclassification,
           change, consolidation, merger to the Targets as in effect immediately
           prior to such reclassification, change, consolidation or merger. Such
           certificate  of incorporation or other charter document shall provide
           for adjustments  which  shall  be  as nearly  equivalent  as  may  be
           practicable  to the adjustments provided for in this paragraph 6. If,
           in the case of any such  consolidation or merger, the stock or  other
           securities  and property  (including cash) receivable  thereupon by a
           holder of  Common Stock  includes shares  of capital  stock or  other
           securities  and property of a corporation other than the successor or
           purchasing corporation, as the case may be, in such consolidation  or
           merger,  then  the  certificate  of  incorporation  or  other charter
           document of  such other  corporation  shall contain  such  additional
           provisions  to  protect the  interests of  the  holders of  shares of
           Series B  Preferred Stock  as shall  be necessary  by reason  of  the
           foregoing.  The provision  of this paragraph  6(f)(v) shall similarly
           apply to successive consolidations or mergers;
 
                (vi) If the  Company shall,  at any time  or from  time to  time
           while  any  of the  Series B  Preferred  Stock is  outstanding, issue
           rights or  warrants to  all holders  of shares  of its  Common  Stock
           entitling them (for a period expiring within 45 days after the record
           date for such issuance) to subscribe for or purchase shares of Common
           Stock  at a price per share less  than the average Stock Price of the
           Common Stock for  the ten (10)  consecutive Trading Days  immediately
           preceding  such  record date  (hereinafter  referred to  as  a 'Below
           Market Rights Issuance'), then, and in  any such case, the number  of
           shares  of Common Stock  into which a  holder may convert  his or her
           Series B Preferred Stock shall be adjusted so that such number  shall
           be  equal to  a number  determined by  multiplying (A)  the number of
           shares of Common Stock into which  such shares of Series B  Preferred
           Stock  was convertible  immediately prior to  such issuance  by (B) a
           fraction (1) the numerator of which shall be the number of shares  of
           Common  Stock outstanding immediately prior to such issuance plus the
           number of additional shares of Common Stock offered for  subscription
           or  purchase  pursuant  to  such  rights  or  warrants  and  (2)  the
           denominator of which shall  be the number of  shares of Common  Stock
           outstanding  immediately prior  to such  issuance plus  the number of
           additional shares which  the aggregate  offering price  of the  total
           number  of  shares of  Common Stock  so  offered for  subscription or
           purchase pursuant to such  rights or warrants  would purchase at  the
           average  Stock Price of the Common Stock for the ten (10) consecutive
           Trading Days immediately  preceding such  record date  for the  Below
           Market Rights Issuance. Such

           adjustment shall become effective retroactively immediately after the
           record date of the Below Market Rights Issuance;
 
                (vii)  If the Company shall make a Below Market Rights Issuance,
           at any time or from time to time while any of the Series B  Preferred
           Stock  is outstanding, then, and in  any such case, the Targets shall
           be adjusted so that the Targets shall be equal to a number determined
           by multiplying (A) each  Target in effect  immediately prior to  such
           Below  Market Rights Issuance by (B)  a fraction (1) the numerator of
           which shall  be the  number  of shares  of Common  Stock  outstanding
           immediately  prior  to such  issuance plus  the number  of additional
           shares which  the aggregate  offering price  of the  total number  of
           shares  of  Common  Stock  so offered  for  subscription  or purchase
           pursuant to such  rights or  warrants would purchase  at the  average
           Stock  Price of the Common Stock for the ten (10) consecutive Trading
           Days immediately  preceding such  record date  for the  Below  Market
           Rights  Issuance and (2) the denominator of which shall be the number
           of shares  of  Common Stock  outstanding  immediately prior  to  such
           issuance plus the number of additional shares of Common Stock offered
           for  subscription or  purchase pursuant  to such  rights or warrants.
           Such adjustment  shall  become  effective  retroactively  immediately
           after the record date of the Below Market Rights Issuance;
 
                (viii)  If the Company shall,  at any time or  from time to time
           while any of the Series B Preferred Stock is outstanding,  distribute
           to  all holders of shares of its  Common Stock cash, evidences of its
           indebtedness, securities or assets (excluding (i) regularly scheduled
           cash dividends, if any,  in amounts determined from  time to time  by
           the  Board or (ii)  dividends payable in shares  of capital stock for
           which adjustment  is  made  under paragraph  6(f)(i))  or  rights  or
           warrants  to  subscribe for  or  purchase securities  of  the Company
           (excluding   those   referred   to   in   paragraph   6(f)(vi))   (an
           'Extraordinary   Distribution'),  then,   unless  such  Extraordinary
           Distribution is made to  each holder of share  of Series B  Preferred
           Stock  on a pro rata  basis with the shares  of Common Stock based on
           the number of shares of Common Stock into which a holder may  convert
           his  or  her Series  B Preferred  Stock  on the  record date  for the
           determination  of  the   stockholders  entitled   to  received   such
           Extraordinary Distribution, in any such case, the number of shares of
           Common  Stock into  which a  holder may convert  his or  her Series B
           Preferred Stock shall be adjusted so that such number shall be  equal
           to  a number  determined by multiplying  (A) the number  of shares of
           Common Stock into which such shares  of Series B Preferred Stock  was
           convertible  immediately prior to  such Extraordinary Distribution by
           (B) a fraction (1) the numerator of which shall be the average  Stock
           Price  of the Common Stock for  the ten (10) consecutive Trading Days
           immediately  preceding  the   record  date   for  the   Extraordinary
           Distribution  and (2) the denominator of  which shall be such average
           Stock Price of the Common Stock for the ten (10) consecutive  Trading
           Days immediately preceding such record date less the then fair market
           value  (as  determined by  the  Board, whose  determination  shall be
           conclusive) of the  portion of  the cash  or assets  or evidences  of
           indebtedness  or securities  so distributed  or of  such subscription
           rights or warrants applicable to one share of Common Stock  (provided
           that  such denominator shall never be less than 1.0). Such adjustment
           shall be made  whenever any such  Extraordinary Distribution is  made
           and shall become effective retroactively immediately after the record
           date of the Extraordinary Distribution;

                (ix)  If the  Company shall,  at any time  or from  time to time
           while any of  the Series B  Preferred Stock is  outstanding, make  an
           Extraordinary   Distribution,   then,   unless   such   Extraordinary
           Distribution is made to  each holder of share  of Series B  Preferred
           Stock  on a pro rata  basis with the shares  of Common Stock based on
           the number of shares of Common Stock into which a holder may  convert
           his  or  her Series  B Preferred  Stock  on the  record date  for the
           determination  of   the  stockholders   entitled  to   receive   such
           Extraordinary  Distribution, in any  such case, each  Target shall be
           adjusted so that the Targets shall be equal to a number determined by
           multiplying (A)  each  Target in  effect  immediately prior  to  such
           Extraordinary  Distribution by  (B) a  fraction (1)  the numerator of
           which shall be the  average Stock Price of  the Common Stock for  the

     (e) Incentive  Stock Options.  Notwithstanding  anything in  Sections  8(a)
through  8(d) to the contrary, no Incentive Stock Option shall be granted to any
Employee who, at  the time the  option is granted  owns (directly or  indirectly
within  the meaning of Section 424(d) of the  Code) more than ten percent of the
total combined  voting  power  of all  classes  of  stock of  Witco  or  of  any
'subsidiary  corporation' (as defined in Section  424(f) of the Code) or 'parent
corporation' (as defined in  Section 424(e) of the  Code) unless (i) the  Option
Price  under such Option is at least 110% of the Fair Market Value of a share of
Common Stock on the date of grant, and (ii) the Option expires no later than the
day preceding the fifth anniversary of the date of grant.
 
     (f) Manner of Exercise and Payment. A Participant shall exercise an Option,
in whole or  in part, by  providing notice  of exercise in  accordance with  the
method prescribed by the Committee and paying the Option Price for each share of
Common  Stock to be purchased under the  Option. Payment of the Option Price may
be made:
 
          (i) in cash  or by check,  bank draft  or money order  payable to  the
     order  of Witco  (or other equivalent  method acceptable  to the Committee)
     equal to the Option Price for the  shares to be exercised, payable in  such
     currency as the Committee determines;
 
          (ii)  through  the delivery  of Common  Stock  with an  aggregate Fair
     Market Value on  the date of  exercise equal  to the Option  Price for  the
     shares to be purchased;
 
          (iii)  through the withholding of  Common Stock issuable upon exercise
     with an  aggregate Fair  Market Value  equal to  the Option  Price for  the
     shares to be purchased;
 
          (iv)  through the delivery of irrevocable  instructions to a broker to
     deliver promptly  to Witco  an amount  equal to  the Option  Price for  the
     shares to purchased; and
 
          (v) by any combination of the above methods of payment;
 
provided, however, that the Company shall not be obligated to purchase or accept
the  surrender in payment of any shares of Common Stock if any such action would
be prohibited by applicable law or if the Committee determines that such  action
is  not in the best interests of  the Company. The Committee shall determine the
method for tendering Common Stock or for delivering irrevocable instructions  to
a  broker and may impose such limitations  and prohibitions on the use of Common
Stock or irrevocable instructions to a broker to exercise an Option as it  deems
appropriate.
 
     (g)  Former Incentive Stock  Option Holders' Notification  Obligation. If a
Participant disposes of Common Stock acquired upon the exercise of an  Incentive
Stock  Option  either (i)  within  two years  after the  date  of grant  of such
Incentive Stock  Option, or  (ii) within  one  year after  the Common  Stock  is
transferred  to  the Participant,  the  Participant shall  notify  the Corporate
Secretary of Witco  of such  disposition and of  the amount  realized upon  such
disposition.

SECTION 9. STOCK APPRECIATION RIGHTS
 
     (a) Stock Appreciation Right Grant. Subject to the terms of this Section 9,
the Committee may grant a Stock Appreciation Right that is (i) independent of an
Option,  or (ii) granted in  conjunction with an Option  (or portion thereof). A
Stock Appreciation Right granted in conjunction with an Option may be granted at
the time the related Option is granted or  at any time prior to the exercise  or
cancellation  of  the  related  Option. Subject  to  the  limitations  on shares
available contained in  Section 5,  the maximum  aggregate number  of shares  of
Common  Stock to  which Stock Appreciation  Right awards to  any Participant may
relate under this Section 9 is 2,000,000 shares.
 
     (b) Grant Price. The 'Grant Price' of a Stock Appreciation Right shall  be:
(i)  in the case of a Stock Appreciation Right that is granted independent of an
Option, no less than  the Fair Market Value  of a share of  Common Stock on  the
date  of  grant; or  (ii) in  the case  of Stock  Appreciation Right  granted in
conjunction with an Option, equal to the Option Price.
 
     (c) Term of  Stock Appreciation  Right. Stock  Appreciation Rights  granted
under  the Plan shall expire no later than ten (10) years from the date of grant
or such earlier date specified by the Committee; provided, however, that a Stock
Appreciation Right granted  in conjunction with  an Option shall  expire at  the
same time the Option expires.
 
     (d)  Exercisability. The  Committee shall  determine the  dates after which
Stock Appreciation  Rights may  be  exercised in  whole  or in  part;  provided,
however, that no Stock Appreciation Right shall be exercisable prior to the date
Witco's  shareholders approve  the Plan  as provided in  Section 6  or after the
expiration of  the  term  of  such Stock  Appreciation  Right.  Subject  to  the
preceding  sentence,  the  Committee may  amend  a Stock  Appreciation  Right to
accelerate the date after which such  Stock Appreciation Right may be  exercised
in  whole or in part. A Stock Appreciation  Right that has not been exercised on
or prior to the date  it expires shall be  canceled. A Stock Appreciation  Right
that  is exercised in conjunction with an  Option (or portion thereof) shall not
be exercised unless such Option  (or portion thereof) is otherwise  exercisable,
and  such a Stock Appreciation Right shall  be canceled to the extent the Option
to which  it relates  has been  exercised, has  expired, or  been terminated  or
canceled.
 
     (e)  Exercise of  Stock Appreciation  Right. A  Participant may  exercise a
Stock Appreciation Right, in whole or  in part, by providing notice of  exercise
in  accordance with the method prescribed by the Committee. Upon the exercise of
a Stock Appreciation Right,  the Participant shall be  entitled to receive  from
the  Company with  respect to  each share  of Common  Stock to  which such Stock
Appreciation Right is exercised an amount in  cash or Common Stock equal to  the
excess  of (i) the Fair Market  Value of a share of  Common Stock on the date of
exercise over  (ii)  the Grant  Price  of  the Stock  Appreciation  Right.  Upon
exercise,  the Company shall pay such amount  in cash and/or Common Stock at the
discretion of  the Committee.  The number  of shares  of Common  Stock, if  any,
issued  as a result of the exercise of a Stock Appreciation Right shall be based
on the Fair Market Value of such shares of Common Stock on the date of exercise.
Upon the exercise of a Stock Appreciation Right (or portion thereof), granted in
conjunction with an Option (or portion thereof), the Option (or portion thereof)
to which such Stock Appreciation Right relates shall be deemed in the case of  a
cash  payment to have been canceled and in the case of a payment in Common Stock
to have been exercised.
 
     (f) Limited  Stock  Appreciation Right.  The  Committee, may  in  its  sole
discretion,  grant 'Limited' Stock  Appreciation Rights in  accordance with this
section. A  Limited  Stock Appreciation  Right  shall  be subject  to  the  same
requirements and treated the same as a Stock Appreciation Right except that:
 
                                      B-6
 
<PAGE>
<PAGE>
          (i) Limited Stock Appreciation Rights may only be exercised within the
     60  day period commencing upon the date of the first public disclosure of a
     Change in Control;
 
          (ii) Upon  the exercise  of a  Limited Stock  Appreciation Right,  the
     Participant  shall be entitled to receive  from the Company with respect to
     each share of Common Stock to  which such Limited Stock Appreciation  Right
     relates  an amount equal to the greater  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
     of  Common  Stock paid  during the  60-day  period immediately  preceding a
     Change in Control; and (C)  the price per share of  Common Stock paid in  a
     tender  offer  subsequent to  a  Change in  Control.  For purposes  of this
     Section 9(f),  if the  consideration  paid for  the 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; and
 
          (iii)  If, following a Change in Control (but prior to the time that a
     'person' as defined in Section 3(f)(i) has acquired, by purchase, merger or
     otherwise, 100% of the 'voting stock,' as defined in Section 3(f)(i) of the
     Company (other than an  acquisition by the Company  or an Affiliate or  any
     employee  benefit plan  sponsored by the  Company or an  Affiliate, as such
     terms are  defined  on the  date  of a  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  who exercised  their Limited Stock  Appreciation Rights during
     the 60-day period following the Change  in Control shall be entitled to  an
     additional  payment (the 'Additional Payment') equal  to the excess if any,
     of the amount the Participant would have received from the exercise of  the
     Limited  Stock Appreciation had  the Subsequent Change  in Control been the
     Change in Control, over  the amount actually paid  to the Participant  upon
     exercise of the Limited Stock Appreciation Right.
 
SECTION 10. RESTRICTED STOCK
 
     (a)  Restricted Stock Grant. Subject  to the terms of  this Section 10, the
Committee may  grant  Restricted  Stock,  the restrictions  on  which  lapse  in
accordance  with  the  terms  specified  by the  Committee.  In  no  event shall
restrictions lapse prior  to approval of  this Plan by  Witco's shareholders  as
provided  in Section  6. Subject  to the  preceding sentence,  the Committee may
amend a Restricted Stock Award to  accelerate the date on which restrictions  on
all  or part of such Award will lapse. As a condition to any Award of Restricted
Stock,  the  Committee  may  require  an  Employee  to  pay  to  the  Company  a
non-refundable  amount equal to, or in excess of, the par value of the shares of
Restricted Stock  awarded.  Subject  to  the  limitations  on  shares  available
contained in Section 5 the maximum number of shares of Restricted Stock that may
be granted to any Participant under this Plan is 1,000,000 shares.
 
     (b)  Restrictions.  During the  Restricted  Period, a  Participant  may not
Transfer any shares of Restricted  Stock except, consistent with Section  17(b),
as provided in the Agreement under which the Restricted Stock is granted.
 
     (c)  No Other Restrictions. Except as otherwise provided in this Section 10
or in an  Agreement in  which Restricted  Stock is  awarded, Participants  shall
enjoy  all  other  rights of  ownership  associated with  the  Restricted Stock,
including, without limitation,  the right  to vote  such shares  and to  receive
dividends on these shares.
 
                                      B-7
 
<PAGE>
<PAGE>
     (d)  Legend. Each certificate  of Common Stock issued  in connection with a
Restricted Stock award under  the Plan shall  be registered in  the name of  the
Participant  to  whom the  Restricted Stock  was  awarded, deposited  with Witco
together with a  stock power  endorsed in  blank, and  bear the  following or  a
substantially similar legend:
 
          THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE GIVEN, SOLD,
     ASSIGNED,  TRANSFERRED, PLEDGED  OR OTHERWISE  DISPOSED OF  (WHETHER FOR OR
     WITHOUT  CONSIDERATION,  AND  WHETHER  VOLUNTARILY,  INVOLUNTARILY  OR   BY
     OPERATION  OF LAW) UNLESS  SUCH GIFT, SALE,  ASSIGNMENT, TRANSFER, OR OTHER
     DISPOSITION COMPLIES WITH THE WITCO  CORPORATION 1997 STOCK INCENTIVE  PLAN
     AND   THE  AGREEMENT  UNDER  WHICH  THE   SECURITIES  WERE  ISSUED  TO  THE
     PARTICIPANT.
 
     (e) Revised Certificates.  When the  restrictions to  which the  Restricted
Stock  is subject lapse or  are otherwise satisfied, Witco  shall deliver to the
Participant holding the Restricted Stock a certificate or certificates of Common
Stock without the legend referred to in Section 10(d), for the number of  shares
of  Restricted  Stock pursuant  to which  all restrictions  have lapsed  or been
satisfied.
 
     (f) Restricted Stock Grants in Connection with Stock Ownership  Guidelines.
From  time to  time the Committee  may establish stock  ownership guidelines for
certain officers and other Employees.  Unless the Committee provides  otherwise,
for  each two shares of Common Stock that each such officer or Employee acquires
with his or her  own resources (i.e.,  without resort to  the loan program  made
available  to such Employees or arranged for by Witco for the purpose of meeting
such guidelines), such officer or Employee  shall receive a grant of  Restricted
Stock,  the restrictions on  which shall lapse  on the third  anniversary of the
date of grant. Such Restricted  Stock Awards shall be made  on the first day  of
the  month following presentation of evidence satisfactory to the Committee that
the requirements to receive such Award have been satisfied.
 
SECTION 11. MERIT AWARDS
 
     The Committee may from time to time make an Award of Common Stock under the
Plan to  selected  Employees  for  such  reasons and  in  such  amounts  as  the
Committee,  in its sole  discretion, may determine.  As a condition  to any such
Merit Award, the Committee may require an Employee to pay the Company an  amount
equal  to, or in excess of, the par value of the shares of Common Stock awarded.
No such Award shall be  made prior to the date  the Plan is approved by  Witco's
shareholders  as provided in Section  5. The maximum number  of shares of Common
Stock that  may be  awarded  as Merit  Awards pursuant  to  this Section  11  is
2,000,000 shares.
 
SECTION 12. PERFORMANCE AWARDS
 
     (a)  Performance Awards. The Committee may from  time to time make an Award
(which may be a Restricted Stock Award, Merit Award or Other Stock Based Award),
the receipt of which, or  the vesting of which,  depends upon the attainment  of
certain  Performance Goals within a stated Performance Period. There may be more
than one Performance Period in  existence at any one  time, and the duration  of
the  Performance Periods may differ from each other. No Performance Award may be
paid prior to the date the Plan is approved by Witco's shareholders as  provided
in  Section  6. Subject  to  the limitations  on  shares available  contained in
Section 5 the maximum number of shares of Common
 
                                      B-8
 
<PAGE>
<PAGE>
Stock with respect to which Performance Awards may be awarded to any Participant
under this Section 12 is 2,000,000 shares.
 
     (b) Granting Performance  Awards. Subject to  the terms of  this Plan,  the
Committee shall determine within the first 90 days of the Performance Period (or
if  shorter,  within  the first  quarter  of  such Performance  Period)  (i) the
Employees who shall  be eligible to  receive a Performance  Award, and (ii)  for
each  such Employee or group of Employees, the Performance Goal and the Award or
range of  Awards  payable  upon  attainment of  such  Performance  Goals  (or  a
percentage of such Performance Goals).
 
     (c)  Revision of Awards or Goals.  The Committee's discretion to revise the
Performance Goals  and the  Awards payable  upon attainment  of the  Performance
Goals  shall  be limited  to  reducing or  eliminating  the amount  of  an Award
otherwise payable upon attainment  of the Performance  Goals. The Committee  may
adjust  Performance  Goals  and  the  Awards  payable  upon  attainment  of  the
Performance Goals during the Performance Period to reflect promotions, transfers
or other changes in  an Employee's employment; provided,  however, that no  such
change shall be effective unless (i) attainment of such Performance Goals is not
substantially  certain, (ii)  the changes  made are  either consistent  with the
Performance Goals and  Awards established  for other  Employees in  the same  or
similar  position  or  approved  by  the  Committee  following  such  promotion,
transfer, or other change in employment,  and are made before the expiration  of
the  first 90 days (or if shorter,  the first quarter) of this short Performance
Period, and  (iii) the  changes would  not cause  the Awards  to be  other  than
'performance-based   compensation'   within   the   meaning   of   Code  Section
162(m)(4)(C).
 
     (d) Determination of Award. Unless the Agreement under which a  Performance
Award  is made  provides otherwise, (i)  Performance Awards  shall be determined
within 90  days  following the  date  attainment  of Performance  Goals  can  be
measured  and (ii) Participants shall receive  their Performance Awards no later
than 30 days  after the  Awards are  determined; provided,  however, no  amounts
shall  be distributed as a result of a  Performance Award prior to the time that
the Committee certifies in writing that the Performance Goals applicable to each
such Award have been  satisfied or prior to  the date Witco's shareholders  have
approved this Plan.
 
SECTION 13. OTHER COMPENSATION PROGRAMS
 
     In the event a compensation program sponsored by the Company provides for a
distribution  to be made in Common Stock,  the Committee may, in its discretion,
treat such distributions as having been  awarded under this Plan. The number  of
shares  of Common Stock, if any, issued as a result of such a distribution shall
be based on the  Fair Market Value of  such shares of Common  Stock on the  date
prior to the date of distribution.
 
SECTION 14. OTHER STOCK BASED AWARD
 
     The  Committee may grant Other Stock Based Awards in such form as it shall,
in its sole discretion, determine, including without limitation, phantom  shares
of  Common Stock  and units representing  shares of Common  Stock. The Committee
shall determine  whether Other  Stock Based  Awards shall  be settled  in  cash,
Common  Stock, or a  combination of both.  Subject to the  limitations on shares
available contained in Section 5, the  maximum number of shares of Common  Stock
with respect to which Other Stock Based Awards may be awarded to any Participant
under this Section 14 is 2,000,000 shares.

SECTION 15. EFFECT OF EMPLOYMENT TERMINATION ON AWARDS
 
     (a)  Termination of Employment: General  Rule. Unless otherwise provided in
an Agreement  and except  as otherwise  provided in  this Section  15, upon  the
termination of employment of a Participant other than for Cause:
 
     (i) each Option, Stock Appreciation Right, and Other Stock Based Award that
is  exercisable shall be  exercisable for the  three-month period following such
termination, provided, that  no such  Award shall be  exercisable following  the
expiration  of its term  and all such  Awards that are  not exercisable shall be
forfeited and canceled;
 
     (ii) each share of Restricted Stock (and each Other Stock Based Award  that
is  subject to restrictions), for  which restrictions have not  lapsed as of the
date employment terminates shall be forfeited and canceled; and
 
     (iii) each  Performance  Award  (and  each Other  Stock  Based  Award  that
requires  attainment of Performance Goals) the award or vesting of which depends
on the performance of the Company during a Performance Period that has not ended
as of the date employment terminates shall be forfeited and canceled.
 
     (b)  Disability,  Death  or  Retirement.  If  a  Participant's   employment
terminates because of Disability, death, or Retirement:
 
     (i) each Option, Stock Appreciation Right, and Other Stock Based Award that
is  exercisable shall  be exercisable for  the three year  period following such
termination, provided, that  no such  Award shall be  exercisable following  the
expiration  of its term  and all such  Awards that are  not exercisable shall be
forfeited and canceled; and
 
     (ii) to  the extent  measurable, the  Participant, or  in the  case of  the
Participant's  death,  the Participant's  beneficiary  shall receive  a pro-rata
award following the Performance Period in respect of each Performance Award (and
each other  Other Stock  Based  Award that  requires attainment  of  Performance
Goals)  the award or vesting of which  depends on the performance of the Company
during a  Performance  Period that  has  not ended  as  of the  date  employment
terminates which shall be determined by multiplying the Award by a fraction, the
numerator of which shall be the number of full and partial months elapsed in the
Performance  Period  during  which  the  Participant  was  an  Employee  and the
denominator of which shall be the number  of full and partial months elapsed  in
the Performance Period.
 
     (c) Termination of Employment for Cause. Upon the termination of employment
of  a Participant for Cause, the Committee may direct the Participant to forfeit
all Awards  which  have not  been  exercised. All  other  Awards which  are  not
exercisable on the date employment terminates, which are restricted or for which
the  Participant  has not  satisfied the  requirements,  shall be  forfeited and
canceled.
 
SECTION 16. AMENDMENT, TERMINATION, TERM
 
     (a) Amendment; Termination. The Board may at any time terminate the Plan or
make such  amendments  thereof  as it  shall  deem  advisable and  in  the  best
interests  of  the Company;  provided, however,  that  no such  amendment shall,
without the consent of the individual to whom any Award shall have been granted,
adversely affect or impair the rights  of such individual under such Award,  and
provided,  further,  that  unless the  shareholders  of Witco  shall  have first
approved thereof, no
 
                                      B-10
 
<PAGE>
<PAGE>
amendment of the Plan  shall be effective if  such amendment would increase  the
number  of shares  of Common  Stock to  be issued  under the  Plan or  for which
shareholder approval  is  required  in  order to  satisfy  the  requirements  of
Sections  162(m) or 422 of the Code. Notwithstanding anything in this Section to
the contrary,  the Committee  may provide  for  forfeiture of  an Award,  if  it
determines,  in  its  complete  discretion that  a  Participant  has  engaged in
activity that is contrary to the interests of the Company.
 
     (b) Term. No  Awards shall be  granted under this  Plan after December  31,
2001, but Awards granted prior to or as of such date may extend beyond such date
in accordance with the provisions of this Plan.
 
SECTION 17. MISCELLANEOUS
 
     (a) Continued Employment/Participation Not Guaranteed. Nothing contained in
this   Plan  shall  confer  upon  any  Participant  or  Employee  the  right  to
continuation of his or  her employment with the  Company (or interfere with  the
Company's  right to terminate such employment) or  the right to receive an Award
under this Plan.
 
     (b) Awards  May Not  Be Transferred.  An Employee  or Participant's  rights
under  this Plan  may not  be Transferred in  whole or  in part  except that the
following Transfers, if permitted by the Agreement under which an Award is made,
shall be permitted under 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) or  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), and their direct lineal descendants) and the Participant's
     parents, brothers and sisters, or a trust, corporation or partnership,  the
     beneficiaries,  stock  holders  or  partners,  respectively  of  which  are
     comprised solely of the Participant's immediate family (any such individual
     or entity a 'Permitted Transferee'); and
 
          (iv) a Transfer from a Permitted Transferee back to the Participant;
 
provided, however, that a Transfer pursuant  to this Section shall not be  given
effect  on the books of Witco unless and until the transferee agrees in writing,
in form and substance satisfactory to the  Committee, to be become bound by  the
terms of the Plan; provided, further, that an Incentive Stock Option may not, by
its  terms,  be transferable  other  than by  will or  the  laws of  descent and
distribution and shall be exercisable,  during the Participant's lifetime,  only
by the Participant.
 
     (c)  Withholding. Applicable law may require  the withholding of taxes from
the income or gains resulting from an Award. The Company, may in its discretion,
require payment to  the Company  of the  amount to  be withheld,  or make  other
arrangements  (including  without limitation,  the  withholding of  Common Stock
which would otherwise be delivered as part of or upon exercise of an Award),  at
the  time of delivery or exercise or  thereafter. To the extent permitted by the
Committee,  a  Participant  may  elect  to  discharge  his  or  her  withholding
obligations  through (i) the payment of cash  or authorization of the Company to
withhold cash that  is otherwise payable  to the Participant,  (ii) delivery  of
shares of
 
                                      B-11
 
<PAGE>
<PAGE>
Common  Stock,  or authorization  of the  Company to  withhold shares  of Common
Stock, having a Fair Market Value equal  to the amount to be withheld, or  (iii)
any combination of the above.
 
     (d)  Certain Adjustments.  In the event  of a corporate  event that affects
Common Stock (i.e.,  a recapitalization, stock  split, stock combination,  stock
reclassification,  merger, or similar event), the Committee may make appropriate
adjustments including,  without  limitation adjustments  to  (i) the  number  of
authorized  and unissued shares  of Common Stock  subject to the  Plan, (ii) the
maximum number of shares available for grant, and (iii) the number of shares  of
Common  Stock, covered by or  available for, or covered  by, an Award, such that
the stock ownership interest of the  Employee shall be maintained as before  the
occurrence of such event.
 
     (e)  Funding; Expenses. This Plan shall be unfunded. Awards hereunder shall
be furnished using the general assets of the Company (or a trust established  by
the  Company to meet its obligations hereunder which shall not be subject to the
claims of Participants) 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. All  of the expenses of the  Plan shall be borne  by
the Company.
 
     (f)  Governing Law; Interpretation. This Plan shall be governed by the laws
of the State of Delaware to the  extent not preempted by federal law. This  Plan
is  intended to be administered with respect to persons covered by Section 16 of
the Exchange  Act in  accordance with  Rule 16b-3  and the  rights of  all  such
individuals shall be construed in accordance with such provision. Options, Stock
Appreciation  Rights,  Performance Awards,  Merit Awards  and Other  Stock Based
Awards granted to officers of the Company in accordance with the requirements of
Code  Section  162(m)   are  intended  to   be  treated  as   'performance-based
compensation' within the meaning of Code Section 162(m)(4)(C), and all rights of
the  Participants under such  Awards shall be construed  in accordance with such
provision.

preceding the  Determination  Date  (as  reported  on  the  Company's  financial
statements) and dividing by 2.

             Subtract the result by the sum  of the incremental amount of  Fixed
        Capital  Investment and Working  Capital Investment during  the year and
        add amortization of intangibles.
 
             Divide the result by the Weighted Average Cost of Capital.

        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 + ([B] x Rm))  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) = 4.9%
 
             [B](Beta) = the [B] for the Company as reported by Bloomberg.
 
             Total  Cost of Debt = weighted average cost of long- and short-term
        debt.

Participant  immediately  prior  to  the  transfer  or  if  the  Participant  is
transferred  to a  new position  for which  no Target  and Target  Percentage of
Salary have been established for the Bonus Period, then:

     Substantially  Certain. If, at the time  of the transfer, the attainment of
     the Target which the Committee established for employees previously holding
     the position to which the Participant was transferred is not  substantially
     certain,  such Target and the  Target Percentage of Salary  (as well as the
     range of Performance Percentages and, if applicable, the Adjustment Factor)
     for such position  shall apply to  the Participant for  the portion of  the
     Bonus  Period beginning on  the date of the  transfer and the Participant's
     Performance Bonus shall be determined  in accordance with Section  8(d)(ii)
     below. Notwithstanding the forgoing, at any time prior to expiration of 25%
     of  the portion of the Bonus  Period following 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  Performance  Bonus  for  such  Bonus  Period  shall  be
     determined  in  accordance with  Section 8(d)(i)  below),  or (B)  that the
     Target and/or Target  Percentage of  Salary applicable  to the  Participant
     immediately  prior to  the transfer  (as well  as the  range of Performance
     Percentages and, if  applicable, the Adjustment  Factor) shall continue  to
     apply   (in  which  case  the  Participant's  Performance  Bonus  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 Target Percentage of Salary applicable to the Participant
     immediately  prior to  the transfer  (as well  as the  range of Performance
     Percentages and, if  applicable, the Adjustment  Factor) shall continue  to
     apply   (in  which  case  the  Participant's  Performance  Bonus  shall  be
     calculated as if the Participant had not been transferred) unless, prior to
     the expiration of 25% of the portion of the Bonus Period which follows  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 Performance Bonus for such Bonus
     Period shall be determined in accordance with Section 8(d)(i)).
 
          (iii)  No  Target   Previously  Established.  If   a  Participant   is
     transferred  to a position  for which a  Target and a  Target Percentage of
     Salary  have  not  previously  been  established,  the  Target  and  Target
     Percentage of Salary applicable to the Participant immediately prior to the
     transfer   shall  continue  to  apply  (in  which  case  the  Participant's
     Performance Bonus shall be  calculated as if the  Participant had not  been
     transferred)  unless prior to the expiration 25% of the Bonus Period during
     which the Employee will be a Participant, 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 Performance
     Bonus for such Bonus Period shall be determined in accordance with  Section
     8(d)(i)) or (B) establishes in writing the Target Percentage of Salary, the
     Performance  Measurements, Target and the range of Performance Percentages,
     and  if  applicable,  the  Adjustment  Factor  and  applicable  Performance
     Measurements  that shall apply to the Participant  on and after the date of
     transfer (in which case Participant's Performance Bonus shall be determined
     in accordance with Section 8(d)(ii)).

          (d) Mid-Bonus Period Changes: Calculation of Performance Bonus.
 
          (i) Participation for Less  Than Full Bonus  Period. If a  Participant
     did  not  participate  in  the  Plan  for  the  entire  Bonus  Period,  the
     Participant's  Performance  Bonus  shall   be  determined  by  taking   the
     Performance  Bonus determined  in accordance with  Section 7(b)  (or if the
     Participant has had a job change resulting in a mid-Bonus Period change  of
     the  Target  and/or  Target  Percentage of  Salary,  the  Performance Bonus
     determined in accordance  with Section  8(d)(ii)) and multiplying  it by  a
     fraction,  the numerator of which  shall be the number  of full and partial
     months elapsed in the  Bonus Period in  which the Participant  participated
     and the denominator of which shall be 12.

     calculated by  adding  (A)  and  (B) below;  provided,  however,  that  the
     Participant's  Performance  Bonus may  not  exceed the  Maximum Performance
     Bonus; and provided, further, the Committee shall have discretion to reduce
     any Participant's Performance Bonus.
 
          (A) Pre-Change Bonus. the Performance Bonus (determined in  accordance
     with  Section  7(b)) using  the  Target(s) and/or  Target  Percentage(s) of
     Salary (as well as the range of Performance Percentages and, if applicable,
     Adjustment  Factor)  prior  to  the  effective  date  of  such  change  and
     multiplying  it by a fraction the numerator of which shall be the number of
     full and  partial months  elapsed  in the  Bonus  Period during  which  the
     Participant  was covered by such Target and Target Percentage of Salary and
     the denominator of which shall be 12.
 
          (B) Post-Change Bonus. the Performance Bonus determined in  accordance
     with  Section 7(b)) using the Target  and/or Target Percentage of Salary in
     effect on  and after  the date  of  the change  (as well  as the  range  of
     Performance   Percentages  and,  if   applicable,  Adjustment  Factor)  and
     multiplying it by a fraction the numerator of which shall be the number  of
     full  and  partial months  elapsed  in the  Bonus  Period during  which the
     Participant was covered by such Target and Target Percentage of Salary  and
     the denominator of which shall be 12.
 
     (e)  Timing. Performance Bonuses  determined under this  Section 8 shall be
determined and paid at the same time that Performance Bonuses are determined and
paid for all other Participants, as prescribed in Section 7.

Performance  Bonuses payable  hereunder to  be 'performance-based compensation',
within the  meaning of  Code  SS 162(m)(4)(C),  shall  be effective  until  such

replacement plan  covering  the  same  time period.  Subject  to  the  foregoing

dividing Net Earnings by Average Equity  and multiplying the result by 100.  For

preceding  the  Determination  Date  (as  reported  on  the  Company's financial
statements) and dividing by 2.

             Subtract  the result by the sum  of the incremental amount of Fixed
        Capital Investment and  Working Capital Investment  during the year  and
        add amortization of intangibles.

        by adding the Weighted Average Cost  of Equity and the Weighted  Average

        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) = 4.9%
 
             [B](Beta) = the [B] for the Company as reported by Bloomberg.
 
             Total Cost of Debt = weighted average cost of long- and  short-term
        debt.
 
             'Working  Capital  Investment'  shall mean  trade  receivables plus
        inventory minus trade  accounts payable,  as reported  on the  Company's

March 21, 1997
 
Dear Witco Shareholder:
 
     I  am  most pleased  to have  the  opportunity to  communicate with  you in
connection with my first Annual Meeting  of Shareholders as Witco's Chairman  of
the  Board and Chief Executive Officer. As you will see in our Annual Report, it
is an  exciting time  for Witco  as we  implement our  new strategies  which  we
believe  will  move  us toward  our  vision  of becoming  the  preeminent global
specialty chemical company.
 
     An important goal  for our company  is to create  additional value for  our
shareholders.  In the proxy statement you will  see that we plan to initiate the
following steps to closely tie shareholder value creation with our  compensation
programs:
 
 We  are  establishing a  unique program  to motivate  our senior  management to
 increase the value of  Witco common stock and  to increase earnings per  share.
 Shareholder approval of the Witco Corporation Shareholder Value Incentive Plan,
 which  is described in detail in  the proxy statement, will permit participants
 to receive  awards of  common stock  if, during  the next  five years,  Witco's
 common  stock reaches a value of at least $75 5/8 per share for ten consecutive
 trading days or its earnings per share in any year reaches at least $4.50.
 
 This program is  unusual as participants  generally do not  benefit unless  the
 stock  price or earnings  per share targets  are met within  the five year time
 frame. Unlike  many incentive  compensation  programs, there  is no  reward  to
 participants unless and until after our shareholders realize a very significant
 increase in the value of their investment.
 
 The   following  data  shows  the  alignment  this  plan  creates  between  its
 participants and Witco's  shareholders. Should  the stock price  target be  met
 within  the five  year time  frame, the  gain to  shareholders would  be $2.878
 billion(1). The gain to  the participants of $151.25  million(2) would be 5.25%
 of  the total increase in shareholder value.
 
 We  plan to grant stock options, or  their equivalent, to every Witco employee,
 including all of those who do  not currently participate in our existing  stock
 option  program.  Shareholder  approval  of the  Witco  Corporation  1997 Stock
 Incentive Plan, which is also described in detail in the proxy statement,  will
 enable  us to proceed with  this important event. In  addition, approval of the
 Stock Incentive Plan gives Witco the flexibility to use Witco common stock in a
 variety of ways  to provide  real opportunities  for our  employees to  benefit
 along  with other shareholders as we increase shareholder value. Our goal is to
 consistently have  at least  90%  of Witco  employees  owning shares  in  their
 company.
 
 Witco's   officers  and   directors  now   have  significant   share  ownership
 requirements, which  will  further align  their  interests with  those  of  our
 shareholders.  These requirements are  described in the  proxy statement. Under
 the Officers' Annual  Incentive Compensation  Plan, which is  described in  the
 proxy  statement, until officers of the  company reach their required ownership
 levels, 20% of any bonus payable under  this plan will be paid in common  stock
 of Witco.
 
     Our  goal is  to encourage  our employees  and managers  to frame  and make
decisions in ways that increase shareholder value. These plans will promote  the
keen   and  decisive  actions  which  are  needed  to  benefit  all  of  Witco's
shareholders. I welcome your  input on these and  other important issues  facing
our company.
 
                                         Very truly yours,

                                         /s/ E. GARY COOK

                                         E. Gary Cook
                                         Chairman, President and Chief Executive
                                         Officer
