                        questions.
                        ------------------------------------------------------------

Q:                      WHO IS ENTITLED TO VOTE?

A:                      Stockholders as of the close of business on the record date,
                        March 1, 2002, are entitled to vote their shares of the
                        Company's common stock. Each outstanding share of common

                        the record date, there were 113,188,090 shares of the
                        Company's common stock outstanding. The Company has no other

                                       1


                     
Q:                      HOW MANY SHARES MUST BE PRESENT TO HOLD THE MEETING?

A:                      A quorum must be present at the meeting for business to be
                        conducted. A quorum is reached when there are present at the
                        meeting, in person or by proxy, the holders of a majority of
                        the shares of the Company's common stock outstanding on the
                        record date. Abstentions and withhold-authority votes will
                        be included for purposes of determining a quorum and for
                        purposes of calculating the vote, but will not be considered
                        to have been voted in favor of the item voted upon. Broker
                        non-votes will be included for purposes of determining a
                        quorum, but will not be considered to be represented at the
                        meeting for purposes of calculating the vote so they will
                        not affect the outcome of any proposal.
                        ------------------------------------------------------------

Q:                      WHAT IF A QUORUM IS NOT PRESENT AT THE MEETING?

A:                      If a quorum is not present at the time of the meeting, the
                        stockholders who are represented may adjourn the meeting
                        until a quorum is present. The time and place of the
                        adjourned meeting will be announced at the time the
                        adjournment is taken, and no other notice will be given.
                        ------------------------------------------------------------

Q:                      HOW DO I VOTE?

A:                      You may vote in any of three ways:

                        *  YOU MAY VOTE BY MAIL if you complete, sign and date the
                        accompanying proxy card and return it in the prepaid
                           envelope. Your shares will be voted confidentially and in
                           accordance with your instructions;

                        *  YOU MAY VOTE BY TELEPHONE OR INTERNET in accordance with
                        the instructions found on your proxy card; and

                        *  YOU MAY VOTE IN PERSON if you are a registered
                        stockholder and attend the meeting and deliver your
                           completed proxy card in person. At the meeting, the
                           Company will also pass out written ballots to registered
                           stockholders who wish to vote in person at the meeting.
                           Beneficial owners of shares held in "street name" who
                           wish to vote at the meeting will need to obtain a proxy
                           form from the institution that holds their shares.
                        ------------------------------------------------------------

Q:                      HOW MANY VOTES DOES IT TAKE TO APPROVE THE ITEMS TO BE VOTED
                        UPON?

A:                      Directors are elected by a plurality. This means that
                        assuming a quorum is present at the meeting, Mr. Fox will be
                        elected if he receives more affirmative votes cast for
                        director than any other person. The affirmative vote of a
                        majority of the shares having voting power present in person
                        or represented by proxy at the meeting is needed to ratify
                        the selection of KPMG LLP as the Company's independent
                        auditors for 2002.
                        ------------------------------------------------------------


                                       2


                     
Q:                      CAN I REVOKE MY PROXY BEFORE IT IS EXERCISED?

A:                      Yes, you may revoke your proxy and change your vote at any
                        time before the polls close at the meeting:

                        *  by signing another proxy with a later date;

                        *  by voting by telephone or on the internet after the date
                        and time of your last telephone or internet vote; or

                        *  if you are a registered stockholder, by giving written
                        notice of such revocation to the Secretary of the Company
                           prior to or at the meeting or by voting in person at the
                           meeting.

                        Attendance at the meeting will not automatically revoke a
                        previously granted proxy.
                        ------------------------------------------------------------

Q:                      WHO WILL COUNT THE VOTES?

                        will tabulate and certify the votes and act as inspector of

                            ELECTION OF ONE DIRECTOR

--------------------------------------------------------------------------------

    The by-laws of the Company provide for a board of directors of not less than
eight nor more than fifteen directors, as determined from time to time by a
resolution of the Board, divided into three classes. Directors of one class are
elected each year for a term of three years. There are currently eight directors
in office, one of whom is standing for election as Class II director whose term
will expire at the 2005 annual meeting, three of whom are Class III directors
whose term will expire at the 2003 annual meeting, and three of whom are
Class I directors whose term will expire at the 2004 annual meeting.

    The Board has nominated Mr. Robert A. Fox to serve as Class II director for
a three-year term expiring at the 2005 annual meeting and until his successor is
elected and has qualified. Mr. Fox is a member of the present Board and has
served as a director since 1990. All of the incumbent directors, including
Mr. Fox, have previously been elected by the stockholders. If Mr. Fox is not
available, an event not anticipated, the proxies will be voted for a substitute
if any is designated by the Board of Directors.

    Mr. Harry G. Hohn will reach age 70 during this fiscal year, the normal
retirement age for directors, and will retire from the Board effective on the
date of the 2002 annual meeting. The Company is currently taking steps to
identify a candidate to fill the vacancy on the Board created by the retirement
of Mr. Hohn.

                            REPORT OF THE COMMITTEE
                           ON EXECUTIVE COMPENSATION

--------------------------------------------------------------------------------

EXECUTIVE COMPENSATION PHILOSOPHY

    The compensation program for the Company's executive officers is
administered in accordance with a pay for performance philosophy to link
executive compensation with the values, objectives, business strategy,
management initiatives and financial performance of the Company. In addition, a
significant portion of each executive officer's compensation is contingent upon
the creation of shareholder value.

    The Organization, Compensation and Governance Committee of the Board (the
"Committee") believes that stock ownership by management and restricted stock-
based performance compensation plans serve to align the interests of management
and other stockholders in the enhancement of shareholder value. To that end,
executive officers are encouraged to retain the shares they earn through the
compensation programs and are given the opportunity to defer receipt of the
shares of common stock.

    The compensation of the Company's executive officers comprises cash and
equity components and is designed to be competitive and highly leveraged based
upon corporate financial performance and shareholder returns. The compensation
program provides an opportunity to earn compensation in the third quartile
within the chemical industry as well as within a broader group of companies of
comparable size and complexity. Actual compensation levels may be greater or
less than competitive levels in surveyed companies based upon annual and
long-term performance of the Company as well as individual performance. Several
performance measures are used for compensation purposes for the Company's
executive officers and heads of the businesses. Primary measures used in the
annual and long-term incentive programs include earnings growth, debt reduction
and market cap growth, with executives also linked to shareholder return through
stock options and restricted performance share awards.

                                       12

BASE SALARIES

    Base salary ranges at the median to 75th percentile levels for executive
officers are determined after reviewing data from several national surveys on
salaries for executives at broad groups of companies of similar size and
complexity.

MANAGEMENT INCENTIVE PLAN

    Annual incentives may be earned under the Company's Management Incentive
Plan. Target and maximum incentives (currently at 175% of target) are set by
formula to offer executive officers an opportunity to earn annual compensation
at the 75th percentile levels if high levels of performance are met.

STOCK OPTIONS AND PERFORMANCE SHARES

    Long-term incentives at the Company consist of annual grants of stock
options and periodic grants of restricted performance shares that can be earned
over a multi-year period based on goals selected by the Committee out of those
approved under the 1998 Long-Term Incentive Plan. Awards are divided evenly in
value between stock options and restricted performance shares and are set at
levels designed to offer opportunities at the 75th percentile.

STOCK OWNERSHIP

    The Company has adopted stock ownership goals for its executive officers,
which range from five times salary for the CEO to two times salary for the
remaining officers. Total stock ownership for this group as of March 1, 2002, is
2,683,562 shares.

TAX DEDUCTIBILITY OF EXECUTIVE COMPENSATION

    The Committee's policy on the tax deductibility of compensation is to
maximize deductibility to the extent possible without abdicating all of its
discretionary power. To this end, the Committee has submitted complying plans to
stockholders; however, the Committee has occasionally taken actions that result
in non-deductible compensation and may do so again in the future when it
determines that such actions are in the Company's best interests.

COMPENSATION OF CHIEF EXECUTIVE OFFICER

    In 2001, the base salary, incentive compensation, stock option and
restricted stock awards for the Chief Executive Officer were determined by the
Board of Directors based on the recommendations of the Committee using the
principles outlined above. The Committee increased Mr. Calarco's base salary
from $825,000 to $865,000 during fiscal year 2001 and granted him a stock option
award of 350,000 shares. Based on the financial performance of the Company,
Mr. Calarco and most other members of senior management were not eligible to
receive an annual incentive payment for 2001 under the terms of the Management
Incentive Plan.

                                       13

ORGANIZATION, COMPENSATION AND GOVERNANCE COMMITTEE

    Decisions on compensation of the Company's executive officers are made by
the Organization, Compensation and Governance Committee, a committee of the
Board of Directors composed of the persons listed below, all of whom are
non-employee directors. The Committee has retained an independent executive
compensation consultant who has access to independent compensation data to
evaluate the Company's executive compensation program.

    The Organization, Compensation and Governance Committee:

                                           Roger L. Headrick, Chairman
                                           Harry G. Hohn

                         REPORT OF THE AUDIT COMMITTEE

--------------------------------------------------------------------------------

    A copy of the written charter of the Audit Committee is attached as
Appendix A to this Proxy Statement. The Company's Audit Committee consists of
four independent members of the Board as defined in Sections 303.01(B)(2)(a) and
(3) of the New York Stock Exchange's listing standards.

    The Audit Committee has reviewed and discussed the audited financial
statements for the fiscal year ended December 31, 2001, with management. The
Audit Committee has also discussed with the Company's independent auditors, KPMG
LLP, the matters required to be discussed by SAS 61. In addition, the Audit
Committee has received the written disclosure from KPMG LLP required by
Independence Standards Board Standard No. 1 and has discussed with KPMG LLP such
auditing firm's independence. Based upon these reviews and discussions, the
Audit Committee recommended that the audited financial statements be included in
the Company's Annual Report on Form 10-K for the last fiscal year for filing
such report with the U.S. Securities and Exchange Commission.

    The Audit Committee:

                                           Bruce F. Wesson, Chairman
                                           Robert A. Fox
                                           C. A. Piccolo
                                           Patricia K. Woolf, Ph.D.

AUDIT FEES

    The aggregate fees billed for professional services rendered by KPMG LLP for
the audit of the Company's annual financial statements for the most recent
fiscal year

                                       14

and the review of the financial statements included in the Company's Quarterly
Reports on Form 10-Q for the fiscal year were $1.9 million.

FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES

    The aggregate fees billed for professional services rendered by KPMG LLP for
financial information systems design and implementation for the most recent
fiscal year were $5.5 million.

ALL OTHER FEES

    The aggregate fees billed for professional services rendered by KPMG LLP
other than audit fees and financial information systems design and
implementation fees for the most recent fiscal year were $2.9 million of which
$1.3 million were audit-related services and $1.6 million were tax-related
services.

    The Audit Committee has considered whether the providing of financial
information systems design and implementation and all other services by KPMG LLP
to the Company is compatible with maintaining the independence of KPMG LLP and
concluded that the independence of KPMG LLP is not compromised by the providing
of such services.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    Messrs. Hohn and Piccolo served as members and Mr. Headrick served as
Chairman of the Organization, Compensation and Governance Committee during the
last completed fiscal year. No member of the Organization, Compensation and
Governance Committee is a current or former officer or employee of the Company
or any of its subsidiaries.

RETIREMENT PLANS

    Each of the persons shown in the Summary Compensation Table on page 17 is
covered by a supplemental retirement agreement with the Company.

    SUPPLEMENTAL RETIREMENT AGREEMENTS WITH VINCENT A. CALARCO AND
GERALD H. FICKENSCHER. In the case of Messrs. Calarco and Fickenscher, the
executive's total annual benefit payable under the supplemental retirement
agreement to the executive for life will be 60% and 50%, respectively, of the
average total compensation (including salary and bonus) paid to the executive
during the highest five years of the last ten years prior to the executive's
normal retirement age.

    SUPPLEMENTAL RETIREMENT AGREEMENTS WITH ALFRED F. INGULLI, WILLIAM A.
STEPHENSON AND JOSEPH B. EISENBERG. In the case of Messrs. Ingulli, Stephenson
and Eisenberg, the executive's retirement benefits under each supplemental
agreement supplement the benefit paid to the executive under a Uniroyal Chemical
Company, Inc. ("Uniroyal") defined benefit pension plan so that the total annual
benefit payable to the executive will be 55% of the average total compensation
(including salary and bonus) paid to the executive during the highest five years
of the last ten years prior to the executive's retirement or, at their election,
Messrs. Ingulli and Eisenberg may receive a lump sum payment earned under a
previous supplemental retirement agreement with Uniroyal.

                                       19

    PROVISIONS FOR REDUCED PAYMENTS UNDER THE SUPPLEMENTAL RETIREMENT
AGREEMENTS. A supplemental benefit in a reduced amount may be payable in the
event of termination of employment prior to normal retirement age. At any time
after the date on which benefit payments commence, the executive may elect to
receive a single lump sum equal to 90% of the actuarial equivalent of the
benefit otherwise payable to the executive. An executive may elect to have the
executive's supplemental benefit under the agreement paid in a form which will
provide for the continuation of benefits, to a beneficiary selected by the
executive, upon the executive's death after retirement. Each agreement also
provides for the payment of a reduced benefit to the executive's beneficiary in
the event of the executive's death prior to normal retirement age and for the
payment of disability benefits in addition to those available under the
Company's regular disability insurance program. Benefits under each agreement
are not payable if the executive voluntarily terminates the executive's
employment, unless such termination is the result of the executive's retirement
(in the case of Mr. Calarco, on or after reaching age 62) or is with approval of
the Board, and meets certain other conditions set forth in the agreement.

    The following table sets forth the estimated aggregate annual benefit
payable to each of the executives named in the table under the executive's
supplemental retirement agreement and from Uniroyal's defined benefit pension
plan upon retirement at or after normal retirement age based on each executive's
compensation history to date and assuming payment of such benefit in the form of
a life annuity:

EMPLOYMENT AGREEMENTS

    EMPLOYMENT AGREEMENT WITH VINCENT A. CALARCO.  Mr. Calarco is employed
pursuant to an employment agreement which was amended and restated in May 1999.
The agreement provides for Mr. Calarco's employment as Chairman of the Board,
President and Chief Executive Officer for a term of three years, with automatic
annual one-year extensions of the term unless the Company gives notice at least
60 days prior to the anniversary of the date of the agreement that the term will
not be extended.

    The amended agreement calls for a base salary of not less than $750,000 and
for Mr. Calarco's continued participation in employee benefit plans and other
fringe benefit arrangements substantially as in the past. In the event
Mr. Calarco's employment is terminated by the Company other than for cause,
disability, or death

                                       20

or by Mr. Calarco for good reason (as defined in the agreement), the Company is
obligated to pay Mr. Calarco his salary to the date of termination, incentive
compensation in an amount no less than the bonus paid to him for the prior year
pro-rated to that date, and a lump sum termination payment equal to three times
the sum of his then current salary and the highest bonus paid to him during the
three years preceding his termination, to continue certain employee and fringe
benefits provided under the agreement for a period of three years or until he
obtains other employment and certain other benefits for the life of Mr. Calarco
and his spouse, and to make certain additional payments to cover any excise tax
imposed under the Internal Revenue Code on the amounts payable as a result of
his termination and any legal fees incurred by Mr. Calarco in enforcing the
Company's obligations under the agreement.

    EMPLOYMENT AGREEMENTS WITH ALFRED F. INGULLI, WILLIAM A. STEPHENSON AND
GERALD H. FICKENSCHER. The Company has entered into employment agreements with
certain other key management employees, including Messrs. Ingulli, Stephenson
and Fickenscher. Each agreement is operative upon the occurrence of a change in
control (as defined in the agreement) and is intended to encourage the executive
to remain in the employ of the Company by providing the executive with greater
security. Absent a change in control, the agreements do not require the Company
to retain the executive or to pay the executive any specified level of
compensation or benefits except that Messrs. Ingulli and Stephenson have
agreements that require that they be paid severance payments in the event that
they are terminated without cause or they resign for good reason (as defined in
the agreements) during an annually renewable two-year period.

    In the event of a change in control, the agreements provide that there will
be no change, without the executive's consent, in the salary, bonus opportunity,
benefits, duties, and location of employment of the executive for a period of
two or three years after the change in control. If, during such period, the
executive's employment is terminated by the Company other than for cause,
disability, or death or the executive resigns for good reason (as defined in the
agreements), the Company will pay the executive his salary to the date of
termination, incentive compensation in an amount no less than the bonus paid to
the executive for the prior year pro-rated to that date, and a lump sum
severance payment equal to two or three times (depending on the executive) the
sum of the executive's base salary and the highest bonus paid to the executive
during the three years preceding the executive's termination and will continue
other employee benefits similar to those provided to the executive prior to the
executive's termination for a period of two or three years or until the
executive's earlier employment with another employer.

                                       21

COMPENSATION OF DIRECTORS

    Members of the Board who are not employees of the Company receive the
following for their services:

    * an annual retainer of $35,000 (committee chairmen receive an additional
retainer of $5,000); and

    * a fee of $12,000 for Board and committee meeting service.

    Directors are reimbursed for expenses incurred in attending meetings. In
addition, the Company provides accidental death and travel insurance coverage
for each non-employee director.

    Each year non-employee directors may elect to defer all or any portion of
their retainers and fees in the form of shares of the Company's Common Stock
pursuant to the Directors Deferred Compensation Plan.

    The Crompton Corporation 1998 Long Term Incentive Plan (the "1998 Plan")
provides for the issuance to non-employee directors on the date of the first
meeting of the Board in the fourth quarter of each year of an option to purchase
up to 20,000 shares of the Company's Common Stock. The exercise price of the
options may not be less than the fair market value of the Company's Common Stock
on the grant date. The options to be granted under the 1998 Plan are
non-qualified options not intended to qualify as incentive stock options under
the Internal Revenue Code of 1986, and may not be exercisable more than
10 years and one month after the date of grant.

    Directors who are employees of the Company receive no additional
compensation for services on the Board of Directors.

                             APPROVAL OF SELECTION
                             OF INDEPENDENT AUDITOR

--------------------------------------------------------------------------------

    The Board of Directors has, subject to approval by the stockholders,
selected the firm of KPMG LLP to act as auditor for the fiscal year 2002. The
Board of Directors recommends a vote FOR approval, and unless otherwise
directed, proxies will be voted in favor of this selection. The affirmative vote
of the holders of a majority of the shares of the Company represented and
entitled to vote at the meeting is required for such approval.

    Representatives of KPMG LLP will be present at the annual meeting, with the
opportunity to make a statement if they desire to do so and to respond to
appropriate questions raised at the meeting.

                                       22

            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

  ----------------------------------------------------------------------------

    Section 16(a) of the Exchange Act requires the Company's officers and
directors, and stockholders who own more than ten percent of a registered class
of the Company's equity securities, to file reports of ownership and changes in
ownership with the Securities and Exchange Commission and the New York Stock
Exchange. Officers, directors and stockholders who own more than ten percent of
such of the Company's securities are required by SEC regulations to furnish the
Company with copies of all Section 16(a) forms they file.

    Based solely on its review of the copies of such forms received by it, or
written representations from certain reporting persons that no Forms 5 were
required for those persons, the Company believes that during fiscal year 2001,
all filings required of its officers, directors and covered stockholders were
made in compliance with applicable SEC regulations.

--------------------------------------------------------------------------------

                                 OTHER MATTERS

--------------------------------------------------------------------------------

    As of the date of this statement, the Board of Directors does not know of
any matter other than those referred to in this Proxy Statement as to which
action is expected to be taken at the annual meeting of stockholders.

    The shares represented by proxies in the form solicited by the Board of
Directors will be voted at the meeting. Where a choice is specified on the proxy
with respect to a matter to be voted upon, the shares represented by the proxy
will be voted in accordance with the specification so made. If no choice is
specified, such shares will be voted (i) for the election as a director of the
one nominee for directorship named herein, and (ii) in favor of the selection of
KPMG LLP as auditor for fiscal year 2002.

    If any business not referred to in this Proxy Statement shall properly come
before the meeting, it is intended that those persons named as proxies will vote
the proxies in accordance with their judgment of the best interests of the
Company and its stockholders.

                                           By Order of the Board of Directors,

                     It is not the duty of the Audit Committee to plan or conduct audits
                     or to determine that the corporation's financial statements are
                     complete and accurate and are in accordance with generally accepted
                     accounting principles. This is the responsibility of management and
                     the independent auditor. Finally, it is not the duty of the Audit
                     Committee to conduct investigations to assure compliance with laws
                     and regulations and the corporation's policies and code of conduct.

MEETINGS:            The Audit Committee meets three times each year in March, July and

                     addition, in each quarter in which the corporation files or releases
                     quarterly financial statements, the chairman of the Audit Committee
                     will meet by telephone or in person with management and the
                     independent auditor prior to such filing or release to determine
                     whether there have been any significant changes in the corporation's
                     accounting principles and whether there are any items required to be
                     communicated by the independent auditors to the Audit Committee in
                     accordance with SAS No. 61. Based upon the outcome of this meeting,
                     the chairman will determine whether or not to convene a meeting of
                     the Audit Committee prior to the filing or release of the quarterly
                     financial statements.
