                  AGREEMENT AND PLAN OF REORGANIZATION, dated as of May 31, 1999
(this "Agreement"), by and among CROMPTON & KNOWLES CORPORATION, a Massachusetts
corporation ("Crompton"), PARK MERGER CO., a Delaware corporation and wholly
owned subsidiary of Crompton ("Newco"), and WITCO CORPORATION, a Delaware
corporation ("Witco").

                  WHEREAS, the Boards of Directors of Witco, Crompton and Newco
have determined that it is in the best interests of their respective companies
and their stockholders to consummate the business combination transaction

immediately thereafter, Witco will, subject to the terms and conditions set
forth herein, merge with and into Newco (the "Second Step Merger" and, together
with the First Step Merger, the "Merger"), so that Newco is the surviving
corporation (hereinafter sometimes referred to in such capacity as the "Combined
Company") in the Second Step Merger; and

                  WHEREAS, as a condition to, and immediately after the
execution of, this Agreement, Crompton and Witco are entering into a Crompton
stock option agreement in the form attached hereto as Exhibit C (the "Crompton
Option Agreement"); and

                  WHEREAS, as a condition to, and immediately after the
execution of, this Agreement, Crompton and Witco are entering into a Witco stock
option agreement in the form attached hereto as Exhibit D (the "Witco Option
Agreement" and, together with the Crompton Option Agreement, the "Option
Agreements"); and

                  WHEREAS, the parties desire to make certain representations,
warranties and agreements in connection with the Merger and also to prescribe
certain conditions to the Merger.

                  NOW, THEREFORE, in consideration of the mutual covenants,
representations, warranties and agreements contained herein, and intending to be
legally bound hereby, the parties agree as follows:


                                    ARTICLE I

                              THE FIRST STEP MERGER


          1.1 The First Step Merger. Subject to the terms and conditions of this
Agreement, in accordance with the Massachusetts Business Corporation Law (the

Commonwealth of the Commonwealth of Massachusetts (the "Massachusetts
Secretary") and the certificate of merger that shall be filed with the Secretary

Step Merger becomes effective, as set forth in the articles of merger and
certificate of merger referred to in this Section 1.2.

          1.3 Effects of the First Step Merger. At and after the First Effective
Time, the First Step Merger shall have the effects set forth in Section 80 of
the MBCL and Sections 259 and 261 of the DGCL.

          1.4 Conversion of Crompton Common Stock. (a) At the First Effective
Time, by virtue of the First Step Merger and without any action on the part of
Crompton, Newco or the holders of common stock of Crompton or Newco, each share
of common stock, par value $.10 per share, of Crompton issued and outstanding
immediately prior to the First Effective Time (together with the rights (the
"Crompton Stockholder Rights") attached thereto issued pursuant to that certain
Rights Agreement, dated July 20, 1988, as amended, between Crompton and The
Chase Manhattan Bank, N.A., as Rights Agent (the "Crompton Rights Agreement"),
"Crompton Common Stock"), other than Dissenting Shares and shares of Crompton
Common Stock held in Crompton's treasury or by Newco, shall be converted into
one share (the "First Merger Exchange Ratio") of common stock, par value $.01
per share, of Newco ( "Newco Common Stock").

          (b) All of the shares of Crompton Common Stock converted into Newco
Common Stock pursuant to this Article I shall no longer be outstanding and shall
automatically be cancelled and shall cease to exist as of the First Effective
Time, and each certificate previously representing any such shares of Crompton
Common Stock (a "Crompton Common Certificate") shall thereafter represent,
without the requirement of any exchange thereof, only the number of shares of
Newco Common Stock into which the shares of Crompton Common Stock represented by
such Crompton Common Certificate have been converted pursuant to this Section
1.4.

          (c) At the First Effective Time, all shares of Crompton Common Stock
that are owned by Crompton as treasury stock and all shares of Crompton Common
Stock that are owned by Crompton or Newco shall be cancelled and shall cease to
exist and no stock of Newco or other consideration shall be delivered in
exchange therefor.

          1.5 Newco Common Stock. At and after the First Effective Time, each
share of Newco Common Stock issued and outstanding immediately prior to the
First Effective Time shall be cancelled and retired and shall resume the status
of authorized and unissued shares of Newco Common Stock, and no shares of Newco
Common Stock or other securities of Newco shall be issued in respect thereof.

Crompton a written demand for appraisal of such shares in the manner provided in

                                      -2-

shall be entitled to payment of the appraised value of such Dissenting Shares in
accordance with the provisions of Section 89 of the MBCL; provided, however,
that (a) if any holder of Dissenting Shares shall subsequently deliver a written
withdrawal of his demand for appraisal of such shares (with the written approval
of the Combined Company if such withdrawal is not tendered within 60 days after
the First Effective Time), or (b) if any holder fails to establish such holder's
entitlement to appraisal rights under the MBCL, such holder shall forfeit the
right to appraisal of such shares of Crompton Common Stock and each of such
shares shall thereupon be deemed to have been converted into, as of the First
Effective Time, Newco Common Stock pursuant to Section 1.4, without interest
thereon.

          1.7 Options. At the First Effective Time, each option granted by

acquire shares of Crompton Common Stock and shall be converted automatically
into an option to purchase a number of shares of Newco Common Stock equal to the
number of shares of Crompton Common Stock subject to such option immediately
prior to the First Effective Time at an exercise price per share of Newco Common
Stock equal to the exercise price per share of Crompton Common Stock in effect
immediately prior to the First Effective Time and otherwise subject to the terms
of the appropriate Crompton Employee Benefit Plan pursuant to which such options
have been issued (such plans, collectively, the "Crompton Stock Plans") and the
agreements evidencing grants thereunder. The adjustment provided herein with
respect to any options that are "incentive stock options" (as defined in Section
422 of the Internal Revenue Code of 1986, as amended (the "Code")) shall be and
is intended to be effected in a manner that is consistent with Section 424(a) of
the Code. The duration and other terms of the new option shall be the same as
the original option, except that all references to Crompton shall be deemed to
be references to Newco.

          1.8 Certificate of Incorporation. Subject to the terms and conditions
of this Agreement, at the First Effective Time, the Certificate of Incorporation
of the surviving corporation in the First Step Merger shall be substantially in
the form attached hereto as Exhibit A (the "Newco Certificate"), with such
changes thereto as shall be mutually agreed upon by Crompton and Witco, until
thereafter amended in accordance with the terms thereof and all applicable laws,
statutes, orders, rules, regulations, policies or guidelines promulgated, or
judgments, decisions or orders entered by any Governmental Authority
(collectively, "Applicable Laws").

          1.9 By-Laws. Subject to the terms and conditions of this Agreement, at
the First Effective Time, the By-Laws of the surviving corporation in the First
Step Merger shall be in substantially the form attached hereto as Exhibit B (the

and Witco, until thereafter amended in accordance with the terms thereof and
Applicable Laws.

Effective Time, until duly changed pursuant hereto or in accordance with the
Newco Certificate, the Newco By-Laws or Applicable Laws, the directors of

the officers of Newco. At the Effective Time, the directors of Newco shall


                                      -3-
<PAGE>

be as set forth in Section 2.11, and the officers of Newco shall be determined
in accordance with Section 2.10.


                                   ARTICLE II

          2.1 The Second Step Merger. Subject to the terms and conditions of
this Agreement, in accordance with the DGCL, at the Effective Time, Witco shall
merge with and into Newco. Newco shall be the surviving corporation in the

corporate existence of Witco shall terminate.

of the Second Step Merger and without any action on the part of Crompton, Newco,
Witco or the holder of any of the following securities:

          (a) Subject to Section 3.2(e), each share of the common stock, par
value $5.00 per share, of Witco issued and outstanding immediately prior to the

of Witco Common Stock held in Witco's treasury, shall be converted into the
right to receive 0.9242 shares (the "Exchange Ratio") of Newco Common Stock.

          (b) All of the shares of Witco Common Stock converted into the right
to receive Newco Common Stock pursuant to this Article II shall no longer be
outstanding and shall automatically be cancelled and shall cease to exist as of
the Effective Time, and each certificate previously representing any such shares
of Witco Common Stock (a "Common Certificate") shall thereafter represent only
the right to receive (i) a certificate representing the number of whole shares
of Newco Common Stock and (ii) cash in lieu of fractional shares into which the
shares of Witco Common Stock represented by such Common Certificate have been
converted pursuant to this Section 2.4 and Section 3.2(e). Common Certificates

                                      -4-
<PAGE>

Section 3.2, without any interest thereon. If, prior to the Effective Time, the
outstanding shares of Witco Common Stock or Crompton Common Stock (or, following

                  the new option shall be equal to the product of the number of
                  shares of Witco Common Stock subject to the original option
                  and the Exchange Ratio, provided that any fractional shares of
                  Newco Common Stock resulting from such multiplication shall be
                  rounded to the nearest whole share; and

          (ii)    The exercise price per share of Newco Common Stock under the
                  new option shall be equal to the exercise price per share of
                  Witco Common Stock under the original option divided by the
                  Exchange Ratio, provided that such exercise price shall be
                  rounded down to the nearest whole cent (as so adjusted, a
                  "Substitute Option").

          (b) The adjustment provided herein with respect to any options that

424(a) of the Code. The duration and other terms of the


                                      -5-

          (c) Within ten (10) days after the Effective Time, Newco shall
register under the Securities Act on Form S-8 or other appropriate form (and use
its reasonable best efforts to maintain the effectiveness thereof) shares of
Newco Common Stock issuable pursuant to all Substitute Options.

          (d) Effective at the Effective Time, Newco shall assume each
Substitute Option in accordance with the plan or arrangement under which it was
issued and the stock option agreement by which it is evidenced.

          2.7 Certificate of Incorporation. Subject to the terms and conditions

                                   ARTICLE III

                               EXCHANGE OF SHARES


          3.1 Newco to Make Shares Available. At or prior to the Effective Time,
Newco shall deposit, or shall cause to be deposited, with ChaseMellon
Shareholder Services, L.L.C., or another bank or trust company reasonably
acceptable to each of Crompton and Witco (the "Exchange Agent"), for the benefit
of the holders of Common Certificates, for exchange in accordance with this
Article III, certificates representing the shares of Newco Common Stock and cash
in lieu of any fractional shares (such cash and certificates for shares of Newco
Common, together with any dividends or distributions with respect thereto, the
"Exchange Fund") to be issued pursuant to Section 2.4 and paid pursuant to
Section 3.2(a) in exchange for outstanding shares of Witco Common Stock.

          3.2 Exchange of Shares. (a) As soon as practicable after the Effective
Time, the Exchange Agent shall mail to each holder of record of one or more
Common Certificates a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Common Certificates shall
pass, only upon delivery of the Common Certificates to the Exchange Agent) and
instructions for use in effecting the surrender of the Common Certificates in
exchange for certificates representing the shares of Newco Common Stock and any
cash in lieu of fractional shares into which the shares of Witco Common Stock
represented by such Common Certificate or Common Certificates shall have been
converted pursuant to this Agreement. Upon proper surrender of a Common
Certificate for exchange and cancellation to the Exchange Agent, together with
such properly completed letter of transmittal, duly executed, the holder of such
Common Certificate shall be entitled to receive in exchange therefor, as
applicable, (i) a certificate representing that number of whole shares of Newco
Common Stock to which such holder of Witco Common Stock shall have become
entitled pursuant to the provisions of Article II and (ii) a check representing
the amount of any cash in lieu of fractional shares that such holder has the
right to receive in respect of the Common Certificate surrendered pursuant to
the provisions of this Article III, and the Common Certificate so surrendered
shall forthwith be cancelled. No interest will be paid or accrued on any cash in
lieu of fractional shares or on any unpaid dividends and distributions payable
to holders of Common Certificates.

          (b) No dividends or other distributions declared with respect to Newco
Common Stock shall be paid to the holder of any unsurrendered Common Certificate
until the holder thereof shall surrender such Common Certificate in accordance
with this Article III. After the surrender of a Common Certificate in accordance
with this Article III, the record holder thereof shall be entitled to receive
any such dividends or other distributions, without any interest thereon, which
theretofore had become payable with respect to shares of Newco Common Stock
represented by such Common Certificate.

          (c) If any certificate representing shares of Newco Common Stock is to
be issued in a name other than that in which the Common Certificate surrendered
in exchange therefor is registered, it shall be a condition of the issuance
thereof that the Common Certificate so surrendered shall be properly endorsed
(or accompanied by an appropriate instrument of transfer) and other-


                                      -7-
<PAGE>

wise in proper form for transfer, and that the person requesting such exchange
shall pay to the Exchange Agent in advance any transfer or other taxes required
by reason of the issuance of a certificate representing shares of Newco Common
Stock in any name other than that of the registered holder of the Common
Certificate surrendered, or required for any other reason, or shall establish to
the satisfaction of the Exchange Agent that such tax has been paid or is not
payable.

          (d) After the Effective Time, there shall be no transfers on the stock
transfer books of Witco of the shares of Witco Common Stock that were issued and
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Common Certificates are presented for transfer to the Exchange Agent, they
shall be cancelled and exchanged for certificates representing shares of Newco
Common Stock as provided in this Article III.

          (e) Notwithstanding anything to the contrary contained herein, no
certificates or scrip representing fractional shares of Newco Common Stock shall
be issued upon the surrender for exchange of Common Certificates, no dividend or
distribution with respect to Newco Common Stock shall be payable on or with
respect to any fractional share, and such fractional share interests shall not
entitle the owner thereof to vote or to any other rights of a stockholder of
Newco. In lieu of the issuance of any such fractional share, Newco shall pay to
each former stockholder of Witco who otherwise would be entitled to receive such
fractional share an amount in cash determined by multiplying (i) the average of
the closing-sale prices of Crompton Common Stock on the New York Stock Exchange,
Inc. (the "NYSE") as reported by The Wall Street Journal, Northeastern edition,
for the five trading days immediately preceding the date of the Effective Time
by (ii) the fraction of a share (rounded to the nearest thousandth when
expressed in decimal form) of Newco Common Stock to which such holder would
otherwise be entitled to receive pursuant to Section 2.4.

          (f) Any portion of the Exchange Fund that remains unclaimed by the
stockholders of Witco for 12 months after the Effective Time shall be paid to
the Combined Company. Any former stockholders of Witco who have not theretofore
complied with this Article III shall thereafter look only to Newco for payment
of the shares of Newco Common Stock, cash in lieu of any fractional shares, and
any unpaid dividends and distributions on the Newco Common Stock deliverable in
respect of each share of Witco Common Stock such stockholder holds as determined
pursuant to this Agreement, without any interest thereon. Notwithstanding the
foregoing, none of Crompton, Newco, Witco, the Exchange Agent or any other
person shall be liable to any former holder of shares of Witco Common Stock for
any amount delivered in good faith to a public official pursuant to applicable
abandoned property, escheat or similar laws.

          (g) The Exchange Agent shall invest any cash included in the Exchange
Fund, as directed by Newco, on a daily basis. Any interest and other income
resulting from such investments shall be paid to the Combined Company upon
termination of the Exchange Fund pursuant to Section 3.2(f).

          (h) In the event any Common Certificate shall have been lost, stolen
or destroyed, upon the making of an affidavit of that fact by the person
claiming such Common Certificate to be lost, stolen or destroyed, the posting by
such person of a bond in such amount as Newco may


                                      -8-
<PAGE>

determine is reasonably necessary as indemnity against any claim that may be
made against it with respect to such Common Certificate, the Exchange Agent will
issue in exchange for such lost, stolen or destroyed Common Certificate the
shares of Newco Capital Stock and any cash in lieu of fractional shares
deliverable in respect thereof pursuant to this Agreement.


                                   ARTICLE IV

              REPRESENTATIONS AND WARRANTIES OF CROMPTON AND NEWCO


               Except as disclosed in a section of the Crompton disclosure
schedule delivered to Witco concurrently herewith (the "Crompton Disclosure
Schedule") reasonably related to the applicable representation and warranty
being qualified, Crompton and Newco hereby represent and warrant to Witco
(subject to Section 10.12) as follows:

          4.1 Organization and Standing. Each of Crompton and its subsidiaries
is a corporation duly organized, validly existing and in good standing under the
laws of its state of incorporation with full power and authority (corporate and
other) to own, lease, use and operate its properties and to conduct its business
as and where now owned, leased, used, operated and conducted. Each of Crompton
and its subsidiaries is duly qualified to do business and in good standing in
each jurisdiction in which the nature of the business conducted by it or the
property it owns, leases or operates makes such qualification necessary, except
where the failure to be so qualified or in good standing in such jurisdiction
have not had or could not reasonably be expected to have a Material Adverse
Effect on Crompton. The term "Material Adverse Effect" means, with respect to
Crompton, Witco or the Combined Company, as the case may be, a material adverse
effect on (a) the business, assets, results of operations or financial condition

party to consummate the transactions contemplated hereby; provided, however,
that Material Adverse Effect shall not be deemed to include the impact of (i)
the United States or global economic or chemical industry conditions generally,
and not specifically relating to such party, (ii) the United States or global
securities markets in general, and not specifically relating to such party,
(iii) changes in legal or regulatory conditions that affect generally, and not
specifically relating to such party, the businesses in which Crompton and Witco
are engaged, (iv) actions or omissions of Crompton, Witco or Newco taken with
the prior written consent of the other in contemplation of the transactions

          4.2 Subsidiaries. As of the date hereof, other than immaterial

been duly authorized by all necessary corporate action on the part of each of
Crompton and Newco, subject to authorization of the Merger and the transactions
contemplated hereby by Crompton Stockholders. This Agreement has been duly
executed and delivered by each of Crompton and Newco, and constitutes the legal,
valid and binding obligation of each of Crompton and Newco, enforceable against

issuance or outstanding. Each outstanding share of Crompton capital stock is,
and all shares of Newco Common Stock to be issued in connection with the Merger
will be, duly authorized and validly issued, fully paid and nonassessable, and
each outstanding share of Crompton capital stock has not been, and all shares of

                                      -12-
<PAGE>

               A "Multiemployer Plan" means any "multiemployer plan" within the
meaning of Section 4001(a)(3) of ERISA.

               "Crompton Employee Benefit Plans" means any material employee
benefit plan, program, policy, practices or other arrangement providing benefits
to any current or former employee, officer or director of Crompton or any of its
subsidiaries or any beneficiary or dependent thereof that is sponsored or

written, including, without limitation, any employee welfare benefit plan within
the meaning of Section 3(1) of ERISA, any employee pension benefit plan within
the meaning of Section 3(2) of ERISA (whether or not such plan is subject to
ERISA) and any bonus, incentive, deferred compensation, vacation, stock
purchase, stock option, severance, employment, change of control or fringe
benefit plan, program or agreement.

               A "Crompton Foreign Plan" shall refer to each material plan,
program or contract that is subject to or governed by the laws of any
jurisdiction other than the United States, and that would have been treated as a
Crompton Employee Benefit Plan had it been a United States plan, program or
contract.

               A "Crompton Plan" means any Crompton Employee Benefit Plan other
than a Multiemployer Plan.

               "Withdrawal Liability" means liability to a Multiemployer Plan as
a result of a complete or partial withdrawal from such Multiemployer Plan (as
such terms are defined in Part I of Subtitle E of Title IV of ERISA).

          (b) Section 4.8 of the Crompton Disclosure Schedule sets forth a true
and complete list of all Crompton Employee Benefit Plans. With respect to each
Crompton Plan, Crompton has made available to Witco a true, correct and complete
copy of: (i) each writing constituting a part of such Crompton Plan, including,
without limitation, all plan documents, benefit schedules, trust agreements, and
insurance contracts and other funding vehicles; (ii) the most recent Annual
Report (Form 5500 Series) and accompanying schedule, if any; (iii) the current
summary plan description, if any; (iv) the most recent annual financial report,
if any; and (v) the most recent determination letter from the Internal Revenue
Service (the "IRS"), if any. Crompton shall make available to Witco within
thirty days following the date of this Agreement a list and copies of the
Crompton Foreign Plans, excluding for this purpose statutorily required
benefits.

          (c) The IRS has issued a favorable determination letter with respect
to each Crompton Plan and the related trust that is intended to be a "qualified
plan" within the meaning of Section 401(a) of the Code (a "Qualified Crompton
Plan"), and there are no existing circumstances nor any events that have
occurred that could adversely affect the qualified status of any Qualified
Crompton Plan or the related trust. Each Crompton Plan that is intended to meet
the requirements of Section 501(c)(9) of the Code is identified in Section 4.8
of the Crompton Disclosure Schedule, and each such Crompton Plan meets such
requirements and provides no disqualified benefits (as such term is defined in
Section 4976(b) of the Code).

                                      -13-
<PAGE>

          (d) All contributions required to be made to any Crompton Plan by
Applicable Laws or by any plan document or other contractual undertaking, and
all premiums due or payable with respect to insurance policies funding any
Crompton Plan, for any period through the date hereof, have been timely made or
paid in full and through the Closing Date will be timely made or paid in full
or, to the extent not required to be made or paid on or before the date hereof
or the Closing Date, as applicable, have been or will be fully reflected on the
financial statements. Each Crompton Employee Benefit Plan that is an employee
welfare benefit plan under Section 3(1) of ERISA is either (i) funded through an
insurance company contract and is not a "welfare benefit fund" within the
meaning of Section 419 of the Code or (ii) unfunded.

          (e) With respect to each Crompton Employee Benefit Plan, Crompton and
its subsidiaries have complied, and are now in compliance, in all material
respects, with all provisions of ERISA, the Code and all laws and regulations
applicable to the Crompton Employee Benefits Plans, and each Crompton Employee
Benefit Plan has been administered in all material respects in accordance with
its terms. There is not now, and there are no existing, circumstances that could
give rise to, any requirement for the posting of security with respect to a
Crompton Plan or the imposition of any lien on the assets of Crompton or any of
its subsidiaries under ERISA or the Code. No prohibited transaction has occurred
with respect to any Crompton Plan from which exemption is unavailable. Neither
Crompton, its subsidiaries nor any of their ERISA Affiliates has engaged in a
transaction in connection with which Crompton, its subsidiaries or any of their
ERISA Affiliates reasonably could be subject to either a material civil penalty
assessed pursuant to Section 409 or 502(i) of ERISA or a material tax imposed
pursuant to Section 4975 or 4976 of the Code.

          (f) With respect to each Crompton Plan that is subject to Title IV or
Section 302 of ERISA or Section 412 or 4971 of the Code: (i) there does not
exist any accumulated funding deficiency within the meaning of Section 412 of
the Code or Section 302 of ERISA, whether or not waived; (ii) the fair market
value of the assets of such Crompton Plan equals or exceeds the actuarial
present value of all accrued benefits under such Crompton Plan (whether or not
vested), based upon the actuarial assumptions used to prepare the most recent
actuarial report for such Crompton Plan; (iii) no reportable event within the
meaning of Section 4043(c) of ERISA for which the 30-day notice requirement has
not been waived has occurred, and the consummation of the transactions
contemplated by this agreement will not result in the occurrence of any such
reportable event; (iv) all premiums to the Pension Benefit Guaranty Corporation
(the "PBGC") have been timely paid in full; (v) no liability (other than for
premiums to the PBGC) under Title IV of ERISA has been or is expected to be
incurred by Crompton; and (vi) the PBGC has not instituted proceedings to
terminate any such Crompton Plan and, to Crompton's knowledge, no condition
exists that presents a risk that such proceedings will be instituted or that
would constitute grounds under Section 4042 of ERISA for the termination of, or
the appointment of a trustee to administer, any such Crompton Plan.

          (g) No Crompton Employee Benefit Plan is a Multiemployer Plan or a
plan that has two or more contributing sponsors at least two of whom are not
under common control, within the meaning of Section 4063 of ERISA (a "Multiple
Employer Plan"). None of Crompton and its subsidiaries nor any of their
respective ERISA Affiliates has, at any time during the last six


                                      -14-
<PAGE>

years, contributed to or been obligated to contribute to any Multiemployer Plan
or Multiple Employer Plan. None of Crompton and its subsidiaries nor any of
their ERISA Affiliates has incurred any Withdrawal Liability that has not been
satisfied in full.

          (h) There does not now exist, and there are no existing, circumstances
that could result in, any Controlled Group Liability that would be a liability
of Crompton or any of its subsidiaries following the Closing. Without limiting
the generality of the foregoing, neither Crompton nor any of its subsidiaries
nor any of their respective ERISA Affiliates has engaged in any transaction
described in Section 4069 or Section 4204 or 4212 of ERISA.

          (i) Except as disclosed in the Crompton Filed SEC Documents, and
except for health continuation coverage as required by Section 4980B of the Code
or Part 6 of Title I of ERISA, neither Crompton nor any of its subsidiaries has
any liability for life, health, medical or other welfare benefits to former
employees or beneficiaries or dependents thereof.

          (j) Neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby (either alone or in
conjunction with any other event) will result in, cause the accelerated vesting
or delivery of, or increase the amount or value of, any payment or benefit to
any employee, officer or director of Crompton or any of its subsidiaries.
Without limiting the generality of the foregoing, no amount paid or payable by
Crompton or any of its subsidiaries in connection with the transactions
contemplated hereby either solely as a result thereof or as a result of such
transactions in conjunction with any other events will be an "excess parachute
payment" within the meaning of Section 280G of the Code.

          (k) There are no pending or threatened claims (other than claims for
benefits in the ordinary course), lawsuits or arbitrations which have been
asserted or instituted against the Crompton Plans, any fiduciaries thereof with
respect to their duties to the Crompton Plans or the assets of any of the trusts
under any of the Crompton Plans that could reasonably be expected to result in
any material liability of Crompton or any of its subsidiaries to the PBGC, the
U.S. Department of Treasury, the U.S. Department of Labor, any Crompton Plan or
any Multiemployer Plan.

          (l) With respect to each Crompton Foreign Plan, Crompton and its
subsidiaries have complied, and are now in compliance, in all material respects,
with applicable local laws and regulations, and all amounts required to be
reserved on account of each Crompton Foreign Plan have been so reserved in
accordance with reasonable accounting practices prevailing in the country where
such Crompton Foreign Plan is established.

          4.9 Crompton SEC Documents. Each of Crompton and its subsidiaries has
timely filed with the Commission all forms, reports, schedules, statements,
exhibits and other documents required to be filed by it since January 1, 1997
under the Securities Exchange Act of 1934, as amended (together with the rules
and regulations promulgated thereunder, the "Exchange Act"), or the Securities
Act of 1933, as amended (together with the rules and regulations promulgated
thereunder, the "Securities Act") (such documents, as supplemented and amended
since the time of filing, collectively, the "Crompton SEC Documents"). The
Crompton SEC Documents, including, without limitation, any financial statements
or schedules included therein, at


                                      -15-
<PAGE>

the time filed (and, in the case of registration statements and proxy

respectively) (a) did not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading, and (b) complied in all material respects with
the applicable requirements of the Exchange Act and the Securities Act, as the
case may be. The financial statements of Crompton included in the Crompton SEC
Documents at the time filed (and, in the case of registration statements and
proxy statements, on the date of effectiveness and the date of mailing,
respectively) complied as to form in all material respects with applicable
accounting requirements and with the published rules and regulations of the
Commission with respect thereto, were prepared in accordance with generally
accepted accounting principles ("GAAP") applied on a consistent basis during the
periods involved (except as may be indicated in the notes thereto, or, in the
case of unaudited statements, as permitted by Form 10-Q of the Commission), and
fairly present (subject in the case of unaudited statements to normal, recurring
and year-end audit adjustments) in all material respects the consolidated

periods then ended.

          4.10 Taxes. Except as set forth in the Crompton Filed SEC Documents,
(a) Crompton has duly filed all U.S. federal and material state and local and

Crompton, (b) all of the foregoing returns and reports are complete and correct
in all material respects, and Crompton has timely paid all taxes shown as due on
such returns or reports, (c) Crompton has paid or made adequate provision (in

the meaning of Section 368(a) of the Code. The term "tax" shall include all U.S.
federal, state and local and foreign taxes, including interest and penalties
thereon and additions thereto.

          4.11 Registration Statement. None of the information provided by
Crompton, Newco or any of their subsidiaries for inclusion in the registration

statement and form of proxies relating to the vote of Witco Stockholders with
respect to the Merger and the vote of Crompton Stockholders with respect to the

          4.16 Undisclosed Liabilities. Except (a) as and to the extent

                     REPRESENTATIONS AND WARRANTIES OF WITCO


               Except as disclosed in a section of the Witco disclosure schedule
delivered to Crompton concurrently herewith (the "Witco Disclosure Schedule")
reasonably related to the applicable representation and warranty being
qualified, Witco hereby represents and warrants to Crompton and Newco as
follows:

          5.1 Organization and Standing. Each of Witco and its subsidiaries is a
corporation duly organized, validly existing and in good standing under the laws
of its state of incorporation with full power and authority (corporate and
other) to own, lease, use and operate its properties and to conduct its business
as and where now owned, leased, used, operated and conducted. Each of Witco and
its subsidiaries is duly qualified to do business and in good standing in each
jurisdiction in which the nature of the business conducted by it or the property
it owns, leases or operates makes such qualification necessary, except where the
failure to be so qualified or in good standing in such jurisdiction have not had
or could not be reasonably expected to have a Material Adverse Effect on Witco.
Neither Witco nor any of its subsidiaries is in default in the performance,
observance or fulfillment of any provision of, in the case of Witco, its
Restated Certificate of Incorporation, as amended (the "Witco Certificate"), or
By-Laws, as amended and restated (the "Witco By-Laws"), or, in the case of any
subsidiary of Witco, its certificate of incorporation, by-laws or other
organizational documents.

          5.2 Subsidiaries. As of the date hereof, other than immaterial
interests, Witco does not own, directly or indirectly, any equity or other
ownership interest in any corporation, partnership, joint venture or other
entity or enterprise. Section 5.2 of the Witco Disclosure Schedule sets forth as
to each subsidiary of Witco: (a) its name and jurisdiction of incorporation or
organization and (b) the percentage of securities owned directly or indirectly
by Witco. Witco owns, directly or indirectly, each of the outstanding shares of
capital stock (or other ownership interests having by their terms ordinary
voting power to elect a majority of directors or others performing similar
functions with respect to such subsidiary) of each of Witco's subsidiaries. Each
of the outstanding shares of capital stock of each of Witco's subsidiaries is
duly authorized, validly issued, fully paid and nonassessable, and is owned,
directly or indirectly, by Witco free


                                      -21-

and clear of all liens, pledges, security interests, claims or other
encumbrances, other than liens imposed by law that could not reasonably be
expected to have, in the aggregate, a Material Adverse Effect on Witco. There
are no outstanding subscriptions, options, warrants, puts, calls, agreements,
understandings, claims or other commitments or rights of any type relating to
the issuance, sale or transfer of any securities of any subsidiary of Witco, nor
are there outstanding any securities that are convertible into or exchangeable
for any shares of capital stock of any subsidiary of Witco; and no subsidiary of
Witco has any obligation of any kind to issue any additional securities or to
pay for securities of any subsidiary of Witco or any predecessor thereof.

          5.3 Corporate Power and Authority. Witco has all requisite corporate

consummation of the transactions contemplated hereby have been duly authorized

          5.5 Conflicts; Consents and Approvals. Neither the execution and

          (b) violate, or conflict with, or result in a breach of any provision
of, or constitute a default (or an event that, with the giving of notice, the
passage of time or otherwise, would constitute a default) under, or entitle any
party (with the giving of notice, the passage of time or otherwise) to
terminate, accelerate, modify or call a default under, or result in the
termination, acceleration or cancellation of, or result in the creation of any
lien, security interest, charge or encumbrance upon any of the properties or

obligations to Goldman Sachs and Deutsche Bank Securities ("Deutsche Bank")

or indirectly, any brokerage, finder's, investment banking or similar fee in
connection with the transactions contemplated by this Agreement. Other than the
foregoing obligations to each of Goldman Sachs and Deutsche Bank, Witco is not
aware of any claim for payment of any finder's fees, brokerage or agent's
commissions or other like payments in connection with the negotiation of this

fide written estimate of the aggregate amount of all fees and expenses


                                      -23-
<PAGE>

Goldman Sachs and Deutsche Bank to the effect that, as of the date hereof, the
Exchange Ratio is fair to the holders of Witco Common Stock from a financial
point of view.

          5.8 Employee Benefit Plans. (a) The following terms have the
definitions given below:

               "Witco Employee Benefit Plans" means any material employee
benefit plan, program, policy, practices or other arrangement providing benefits
to any current or former employee, officer or director of Witco or any of its
subsidiaries or any beneficiary or dependent thereof that is sponsored or
maintained by Witco or any of its subsidiaries or to which Witco or any of its
subsidiaries contributes or is obligated to contribute, whether or not written,
including, without limitation, any employee welfare benefit plan within the
meaning of Section 3(1) of ERISA, any employee pension benefit plan within the
meaning of Section 3(2) of ERISA (whether or not such plan is subject to ERISA)
and any bonus, incentive, deferred compensation, vacation, stock purchase, stock
option, severance, employment, change of control or fringe benefit plan, program
or agreement.

               A "Witco Foreign Plan" shall refer to each material plan, program
or contract that is subject to or governed by the laws of any jurisdiction other
than the United States, and that would have been treated as a Witco Employee
Benefit Plan had it been a United States plan, program or contract.

               A "Witco Plan" means any Witco Employee Benefit Plan other than a
Multiemployer Plan.

          (b) Section 5.8 of the Witco Disclosure Schedule sets forth a true and
complete list of all Witco Employee Benefit Plans. With respect to each Witco
Plan, Witco has made available to Crompton a true, correct and complete copy of:
(i) each writing constituting a part of such Witco Plan, including, without
limitation, all plan documents, benefit schedules, trust agreements, and
insurance contracts and other funding vehicles; (ii) the most recent Annual
Report (Form 5500 Series) and accompanying schedule, if any; (iii) the current
summary plan description, if any; (iv) the most recent annual financial report,
if any; and (v) the most recent determination letter from the IRS, if any. Witco
shall make available to Crompton within thirty days following the date of this
Agreement a list and copies of the Witco Foreign Plans, excluding for this
purpose statutorily required benefits.

          (c) The IRS has issued a favorable determination letter with respect
to each Witco Plan and the related trust that is intended to be a "qualified
plan" within the meaning of Section 401(a) of the Code (a "Qualified Witco
Plan"), and there are no existing circumstances nor any events that have
occurred that could adversely affect the qualified status of any Qualified Witco
Plan or the related trust. Each Witco Plan that is intended to meet the
requirements of Section 501(c)(9) of the Code is identified in Section 5.8 of
the Witco Disclosure Schedule, and each such Witco


                                      -24-
<PAGE>

Plan meets such requirements and provides no "disqualified benefits" (as defined
in Section 4976(b) of the Code).

          (d) All contributions required to be made to any Witco Plan by
Applicable Laws or by any plan document or other contractual undertaking, and
all premiums due or payable with respect to insurance policies funding any Witco
Plan, for any period through the date hereof, have been timely made or paid in
full and through the Closing Date will be timely made or paid in full or, to the
extent not required to be made or paid on or before the date hereof or the
Closing Date, as applicable, have been or will be fully reflected on the
financial statements. Each Witco Employee Benefit Plan that is an employee
welfare benefit plan under Section 3(1) of ERISA is either (i) funded through an
insurance company contract and is not a "welfare benefit fund" within the
meaning of Section 419 of the Code or (ii) unfunded.

          (e) With respect to each Witco Employee Benefit Plan, Witco and its
subsidiaries have complied, and are now in compliance, in all material respects,
with all provisions of ERISA, the Code and all laws and regulations applicable
to the Witco Employee Benefits Plans and each Witco Employee Benefit Plan has
been administered in all material respects in accordance with its terms. There
is not now, and there are no existing, circumstances that could give rise to,
any requirement for the posting of security with respect to a Witco Plan or the
imposition of any lien on the assets of Witco or any of its subsidiaries under
ERISA or the Code. No prohibited transaction has occurred with respect to any
Witco Plan from which exemption is unavailable. Neither Witco, its subsidiaries
nor any of their ERISA Affiliates has engaged in a transaction in connection
with which Witco, its subsidiaries or any of their ERISA Affiliates reasonably
could be subject to either a material civil penalty assessed pursuant to Section
409 or 502(i) of ERISA or a material tax imposed pursuant to Section 4975 or
4976 of the Code.

          (f) With respect to each Witco Plan that is subject to Title IV or
Section 302 of ERISA or Section 412 or 4971 of the Code: (i) there does not
exist any accumulated funding deficiency within the meaning of Section 412 of
the Code or Section 302 of ERISA, whether or not waived; (ii) the fair market
value of the assets of such Witco Plan equals or exceeds the actuarial present
value of all accrued benefits under such Witco Plan (whether or not vested),
based upon the actuarial assumptions used to prepare the most recent actuarial
report for such Witco Plan; (iii) no reportable event within the meaning of
Section 4043(c) of ERISA for which the 30-day notice requirement has not been
waived has occurred, and the consummation of the transactions contemplated by
this agreement will not result in the occurrence of any such reportable event;
(iv) all premiums to the PBGC have been timely paid in full; (v) no liability
(other than for premiums to the PBGC) under Title IV of ERISA has been or is
expected to be incurred by Witco; and (vi) the PBGC has not instituted
proceedings to terminate any such Witco Plan and, to Witco's knowledge, no
condition exists that presents a risk that such proceedings will be instituted
or which would constitute grounds under Section 4042 of ERISA for the
termination of, or the appointment of a trustee to administer, any such Witco
Plan.
          (g) No Witco Employee Benefit Plan is a Multiemployer Plan or Multiple
Employer Plan. None of Witco and its subsidiaries nor any of their respective
ERISA Affiliates has, at any time during the last six years, contributed to or
been obligated to contribute to any Multiem-


                                      -25-
<PAGE>

ployer Plan or Multiple Employer Plan. None of Witco and its subsidiaries nor
any of their ERISA Affiliates has incurred any Withdrawal Liability that has not
been satisfied in full.

          (h) There does not now exist, and there are no existing, circumstances
that could result in, any Controlled Group Liability that would be a liability
of Witco or any of its subsidiaries following the Closing. Without limiting the
generality of the foregoing, neither Witco nor any of its subsidiaries nor any
of their respective ERISA Affiliates has engaged in any transaction described in
Section 4069 or Section 4204 or 4212 of ERISA.

          (i) Except as disclosed in the Witco Filed SEC Documents, and, except
for health continuation coverage as required by Section 4980B of the Code or
Part 6 of Title I of ERISA, neither Witco nor any of its subsidiaries has any
liability for life, health, medical or other welfare benefits to former
employees or beneficiaries or dependents thereof.

          (j) Neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby (either alone or in
conjunction with any other event) will result in, cause the accelerated vesting
or delivery of, or increase the amount or value of, any payment or benefit to
any employee, officer or director of Witco or any of its subsidiaries. Without
limiting the generality of the foregoing, no amount paid or payable by Witco or
any of its subsidiaries in connection with the transactions contemplated hereby
either solely as a result thereof or as a result of such transactions in
conjunction with any other events will be an "excess parachute payment" within
the meaning of Section 280G of the Code.

          (k) There are no pending or threatened claims (other than claims for
benefits in the ordinary course), lawsuits or arbitrations that have been
asserted or instituted against the Witco Plans, any fiduciaries thereof with
respect to their duties to the Witco Plans or the assets of any of the trusts
under any of the Witco Plans that could reasonably be expected to result in any
material liability of Witco or any of its subsidiaries to the PBGC, the U.S.
Department of Treasury, the U.S. Department of Labor, any Witco Plan or any
Multiemployer Plan.

          (l) With respect to each Witco Foreign Plan, Witco and its
subsidiaries have complied, and are now in compliance, in all material respects,
with applicable local laws and regulations, and all amounts required to be
reserved on account of each Witco Foreign Plan have been so reserved in
accordance with reasonable accounting practices prevailing in the country where
such Witco Foreign Plan is established.

          5.9 Witco SEC Documents. Each of Witco and its subsidiaries has timely
filed with the Commission all forms, reports, schedules, statements, exhibits
and other documents required to be filed by it since January 1, 1997 under the
Exchange Act or the Securities Act (such documents, as supplemented and amended
since the time of filing, collectively, the "Witco SEC Documents"). The Witco
SEC Documents, including, without limitation, any financial statements or
schedules included therein, at the time filed (and, in the case of registration
statements and proxy statements, on the dates of effectiveness and the dates of
mailing, respectively) (a) did not contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
in order to make the statements therein, in light of the circumstances under
which they were made, not misleading, and (b) complied in all material respects
with the


                                      -26-
<PAGE>

proceeding or investigation in which any individual who is now, or has been at
any time prior to the date of this Agreement, or who becomes prior to the
Effective Time, a director or officer or employee of Crompton, Witco, Newco or
any of their respective subsidiaries, including any entity specified in the
Crompton Disclosure Schedule or the Witco Disclosure Schedule (the "Indemnified
Parties"), is, or is threatened to be, made a party based in whole or in part
on, or arising in whole or in part out of, or pertaining to (i) the fact that he
or she is or was a director, officer or employee of Crompton, Witco, Newco or
any of their respective subsidiaries or any entity specified in the Crompton
Disclosure Schedule or the Witco Disclosure Schedule or any of their respective
predecessors or (ii) this Agreement, the Option Agreements or any of the
transactions contemplated hereby or thereby, whether, in any case, asserted or
arising before or after the Effective Time, the parties hereto agree to
cooperate and use their reasonable best efforts to defend against and respond
thereto. It is understood and agreed that after the Effective Time, Newco shall
indemnify and hold harmless, as and to the fullest extent permitted by
Applicable Law, each such Indemnified Party against any losses, claims, damages,
liabilities, costs, expenses (including reasonable attorney's fees and expenses
in advance of the final disposition of any claim, suit, proceeding or
investigation to each Indemnified Party to the fullest extent permitted by law
upon receipt of any undertaking required by Applicable Laws), judgments, fines
and amounts paid in settlement in connection with any such threatened or actual
claim, action, suit, proceeding or investigation, and, in the event of any such
threatened or actual claim, action, suit, proceeding or investigation (whether
asserted of arising before or after the Effective Time); and Newco, after
consultation with an Indemnified Party, shall retain counsel and direct the
defense thereof, provided, however, that by virtue of the obligations herein set
forth, Newco shall not be liable to any Indemnified Party for any legal expenses
of other counsel or any other expenses incurred by any Indemnified Party in
connection with the defense thereof, except that if


                                      -35-
<PAGE>

Newco fails or elects not to assume such defense or counsel for the Indemnified
Parties reasonably advises the Indemnified Parties that there are issues that
raise conflicts of interest between Newco and the Indemnified Parties, the
Indemnified Parties may retain counsel reasonably satisfactory to them after
consultation with Newco, and Newco shall pay the reasonable fees and expenses of
such counsel for the Indemnified Parties, (i) Newco shall be obligated pursuant
to this paragraph to pay for only one firm of counsel for all Indemnified
Parties, unless an Indemnified Party shall have reasonably concluded, based on
the advice of counsel and after consultation with Newco, that in order to be
adequately represented, separate counsel is necessary for such Indemnified
Party, in which case, Newco shall be obligated to pay for such separate counsel,
(ii) Newco shall not be liable for any settlement effected without its prior
written consent (which consent shall not be unreasonably withheld) and (iii)
Newco shall have no obligation hereunder to any Indemnified Party when and if a
court of competent jurisdiction shall ultimately determine, and such
determination shall have become final and nonappealable, that indemnification of
such Indemnified Party in the manner contemplated hereby is prohibited by
Applicable Laws. Any Indemnified Party wishing to claim Indemnification under
this Section 7.2(c), upon learning of any such claim, action, suit, proceeding
or investigation, shall notify Newco thereof, provided that the failure to so
notify shall not affect the obligations of Newco under this Section 7.2(c)
except to the extent such failure to notify materially prejudices Newco. Newco's
obligations under this Section 7.2(c) continue in full force and effect for a
period of six years from the Effective Time (or the period of the applicable
statute of limitations, if longer); provided, however, that all rights to
indemnification in respect of any claim (a "Claim") asserted or made within such
period shall continue until the final disposition of such Claim.

          (d) Directors' and Officers' Insurance. Crompton (and Newco, from and
after the First Effective Time) shall use its reasonable best efforts to cause
the individuals serving as officers and directors of Crompton, Newco or Witco,
their respective subsidiaries or any entity specified in the Crompton Disclosure
Schedule or the Witco Disclosure Schedule immediately prior to the First
Effective Time or Effective Time, as the case may be, to be covered for a period
of six years from the Effective Time (or the period of the applicable statute of
limitations, if longer) by the directors' and officers' liability insurance
policy maintained by Crompton or Witco, as the case may be (provided that Newco
may substitute therefor policies of at least the same coverage and amounts
containing terms and conditions that are not less advantageous than such policy)
with respect to acts or omissions occurring prior to the Effective Time that
were committed by such officers and directors in their capacity as such;
provided, however, that in no event shall Newco be required to expend more than
200% of the current amount expended by Crompton or Witco, as the case may be
(the "Insurance Amount") to maintain or procure insurance coverage pursuant
hereto, and provided, further, that, if Newco is unable to maintain or obtain
the insurance called for by this Section 7.2(d), Newco shall use its best
efforts to obtain as much comparable insurance as available for the Insurance
Amount.

          (e) Employee Benefits. (i) From and after the Effective Time, the
Crompton Plans and the Witco Plans in effect as of the date of this Agreement
shall remain in effect with respect to employees of Newco or Witco (or their
subsidiaries), respectively, covered by such plans at the Effective Time until
such time as the Combined Company shall, subject to Applicable Laws, the terms
of this Agreement and the terms of such plans, adopt new benefit plans, or
modify or


                                      -36-
<PAGE>

consolidate the existing plans, with respect to employees of Newco or Witco and
their subsidiaries, respectively (the "New Benefit Plans"). Crompton and Witco
shall cooperate in reviewing, evaluating and analyzing the Crompton Plans and
the Witco Plans with a view towards developing appropriate New Benefit Plans for
the employees covered thereby subsequent to the Second Step Merger. It is the
intention of Crompton and Witco to develop New Benefit Plans, as soon as
reasonably practicable after the Effective Time, which, among other things,
treat similarly situated employees on a substantially equivalent basis, taking
into account all relevant factors, including, without limitation, duties,
geographic location, tenure, qualifications and abilities and competitive
industry practices. Notwithstanding the foregoing, employees of the Combined
Company and its subsidiaries who are covered under a collective bargaining
agreement shall be provided with benefits as are from time to time required by
such collective bargaining agreement.

               (ii) The foregoing notwithstanding, the Combined Company agrees
to honor in accordance with their terms all benefits vested as of the date
hereof under the Crompton Plans or the Witco Plans or under other contracts,
arrangements, commitments, or understandings described in the Crompton
Disclosure Schedule and the Witco Disclosure Schedule.

               (iii) Nothing in this Section 7.2(e) shall be interpreted as
preventing the Combined Company from amending, modifying or terminating any of
the Crompton Plans, the Witco Plans, or other contracts, arrangements,
commitments or understandings, in accordance with their terms and Applicable
Laws.

          (f) Notification of Certain Matters. Crompton shall give prompt notice
to Witco of (i) the occurrence or non-occurrence of any event the occurrence or
non-occurrence of which would cause any Crompton or Newco representation or
warranty contained in this Agreement to be untrue or inaccurate at or prior to
the Effective Time such that the condition set forth in Section 8.3(a) would not
be satisfied and (ii) any material failure of Crompton or Newco to comply with
or satisfy any covenant, condition or agreement to be complied with or satisfied
by it hereunder; provided, however, that the delivery of any notice pursuant to
this Section 7.2(f) shall not limit or otherwise affect the remedies available
hereunder to Witco.

          (g) No Solicitation. (i) Crompton agrees that, during the term of this
Agreement, it shall not, and shall not authorize or permit any of its
subsidiaries or any of its or its subsidiaries' directors, officers, employees,
agents or representatives, directly or indirectly, to (A) solicit, initiate,
encourage or facilitate, or furnish or disclose non-public information in
furtherance of, any inquiries or the making of any proposal with respect to any
recapitalization, merger, consolidation or other business combination involving
Crompton, or acquisition of any capital stock or any material portion of the
assets (except for acquisition of assets in the ordinary course of business
consistent with past practice, transactions disclosed in the Crompton Disclosure
Schedule and the transactions contemplated by this Agreement) of Crompton, or
any combination of the foregoing (a "Crompton Competing Transaction") or (B)
negotiate, explore or otherwise engage in discussions with any person (other
than Witco or its directors, officers, employees, agents and representatives)
with respect to any Crompton Competing Transaction. Crompton will immediately
cease all existing activities, discussions and negotiations with any parties
conducted hereto-


                                      -37-

efforts to enforce any confidentiality or similar agreement relating to a
Crompton Competing Transaction. From and after the execution of this Agreement,
Crompton shall immediately advise Witco in writing of the receipt, directly or
indirectly, of any inquiries, discussions, negotiations, or proposals relating
to a Crompton Competing Transaction (including the specific terms thereof), and
promptly furnish to Witco a copy of any such proposal or inquiry in addition to
any information provided to or by any third party relating thereto.
Notwithstanding the foregoing, prior to receipt of the Crompton Stockholders
Approval, Crompton may, but only to the extent required by the fiduciary
obligations of its Board of Directors under Applicable Law, as determined in
good faith and on a reasonable basis by such Board of Directors and based on the
written advice of outside counsel that not to so act would constitute a
violation of such fiduciary obligations, in response to a publicly disclosed
proposal for a Crompton Competing Transaction that constitutes a Qualifying
Crompton Proposal that was not solicited or encouraged by Crompton or its
representatives and that did not otherwise result from the breach or a deemed
breach of this Section 7.2(g), and subject to compliance with the notification
provisions of this Section 7.2(g), for a 10-day period commencing with the first
notification to Witco under this Section 7.2(g) of receipt of such Crompton
Competing Transaction, (x) furnish non-public information with respect to
Crompton to the person proposing such Crompton Competing Transaction and its
representatives pursuant to a confidentiality agreement with terms no less
restrictive of such person than those set forth in the Confidentiality Agreement
and (y) participate in discussions or negotiations with such person and its
representatives regarding such Crompton Competing Transaction.

          (ii) Neither the Board of Directors of Crompton nor any committee
thereof shall (A) withdraw or modify, or propose to withdraw or modify, in a
manner adverse to Witco, the approval or recommendation by the Board of
Directors of Crompton of this Agreement and the transactions contemplated
hereby, (B) approve, or permit or cause Crompton to enter into, any definitive
agreement providing for the implementation of any Crompton Competing Transaction
(each a "Crompton Acquisition Agreement") or (C) approve or recommend, or
propose to approve or recommend, any Crompton Competing Transaction.
Notwithstanding the foregoing, prior to receipt of the Crompton Stockholders
Approval, and only to the extent required by the fiduciary obligations of the
Crompton Board of Directors under Applicable Law, as determined in good faith
and on a reasonable basis by such Board of Directors and based on the written
advice of outside counsel that not to so act would constitute a violation of
such fiduciary obligations, in response to a publicly disclosed proposal for a
Crompton Competing Transaction that constitutes a Qualifying Crompton Proposal
that was not solicited or encouraged by Crompton or its representatives and that
did not otherwise result from the breach or a deemed breach of this Section
7.2(g), (I) the Board of Directors of Crompton may withdraw or modify its
approval or recommendation of the transactions contemplated by this Agreement
and, in connection therewith, approve or recommend such Qualifying Crompton
Proposal and (II) Crompton may enter into a Crompton Acquisition Agreement
contemporaneously with its termination of this Agreement pursuant to Section
9.1(h).

          (iii) Nothing contained in this Section 7.2(g) shall prohibit Crompton
from taking and disclosing to its stockholders a position contemplated by Rule
14e-2(a) promulgated under the Exchange Act.

                                      -38-

determined by the Board of Directors of Crompton) and is comprised solely of

recognized independent investment banking firm has opined in writing (with only
customary qualifications) to be superior from a financial point of view to the

and this Agreement (including the terms of any proposal by Witco to amend or
modify the terms of the transactions contemplated by this Agreement), and (C)
reasonably capable of being completed within 7 months of the termination of this
Agreement, taking into account all financial, regulatory, legal and other
aspects of such proposal.

          (h) Listing Application. Crompton shall, as soon as practicable
following the date hereof, prepare and submit to the NYSE a listing application
covering the shares of Newco Common Stock issuable in the Merger, and shall use
its reasonable best efforts to obtain, prior to the Effective Time, approval for
the listing of such shares of Newco Common Stock, subject to official notice of
issuance.

          (i) Exemption from Liability Under Section 16(b). Assuming that Witco
delivers to Crompton the Section 16 Information in a timely fashion, the Board

Insider and expected to be exchanged for Newco Common Stock in the Merger, and
the number and description of the options on Witco Common Stock held by each
such Witco Insider and expected to be converted into options on Newco Common

Time or any termination of this Agreement pursuant to Article IX, Crompton
agrees that it shall not, without Witco's consent, redeem the Crompton
Stockholder Rights, amend or modify the Crompton Rights Agreement or take any
other action that could result in the Crompton Rights Agreement being deemed
inapplicable to any person other than Witco and Newco.

          (k) Takeover Laws; Governance Documents. Crompton shall take no action
that would cause any Crompton Competing Transaction to be exempt from any
requirements im-


                                      -39-
<PAGE>

reasonable best efforts to have the Registration Statement declared effective by

(including the terms of any proposal by Crompton to amend or modify the terms of
the transactions contemplated by this Agreement), and (C) reasonably capable of

covenant, condition or agreement to be complied with or satisfied by it
hereunder; provided, however, that the delivery of any notice pursuant to this
Section 7.3(h) shall not limit or otherwise affect the remedies available
hereunder to Crompton.

                   (e) No Injunctions or Restraints; Illegality. No order,
         injunction or decree issued by any court or agency of competent
         jurisdiction or other legal restraint or prohibition (an "Injunction")
         preventing the consummation of the First Step Merger, the Second Step
         Merger or any of the other transactions contemplated by this Agreement
         shall be in effect.

                    (f) Federal Tax Opinion. Crompton and Witco shall have
          received an opinion of Wachtell, Lipton, Rosen & Katz and Cravath,
          Swaine & Moore, respectively, in form and substance reasonably
          satisfactory to Crompton and Witco, respectively, in each case, dated
          the Closing Date, substantially to the effect that, on the basis of
          facts, representations and assumptions set forth in such opinion that
          are consistent with the state of facts existing at the Effective Time,
          each of the First Step Merger and the Second Step Merger will
          constitute a "reorganization" under Section 368(a) of the Code;
          Crompton and Newco will each be a party to the reorganization in
          respect of the First Step Merger; and Newco and Witco will each be a
          party to the reorganization in respect of the Second Step Merger.

                  In rendering such opinion, counsel may require and rely upon
representations contained in certificates of officers of Crompton, Newco, Witco
and others.

          8.2 Conditions to Obligations of Crompton and Newco. The obligations
of Crompton and Newco to effect the First Step Merger, and the obligation of
Newco to effect the Second Step Merger, are also subject to the satisfaction, or
waiver by Crompton or Newco, at or prior to the Effective Time, of the following
conditions:

                    (a) Representations and Warranties. The representations and
          warranties of Witco set forth in this Agreement shall be true and

          (except to the extent such representations and warranties speak as of
          an earlier date) as of the Closing Date as though made on and as of
          the Closing Date, provided, however, that for purposes of this
          paragraph, such representations and warranties shall be deemed to be
          true and correct unless the failure or failures of such
          representations and warranties to be so true and correct, individually
          or in the aggregate, and without giving effect to any qualification as
          to materiality set forth in such representations or warranties, has
          had or could reasonably be expected to have a Material Adverse Effect
          on Witco. Crompton shall have received a certificate signed on behalf
          of Witco by the Chief Executive Officer and the Chief Financial
          Officer of Witco to the foregoing effect.

          8.3 Conditions to Obligations of Witco. The obligation of Witco to
effect the Second Step Merger is also subject to the satisfaction or waiver by
Witco at or prior to the Effective Time of the following conditions:

                    (a) Representations and Warranties. The representations and
          warranties of Crompton and Newco set forth in this Agreement shall be
          true and correct in all material respects as of the date of this
          Agreement and (except to the extent such representations and
          warranties speak as of an earlier date) as of the Closing Date as
          though made on and as of the Closing Date; provided, however, that,
          for purposes of this paragraph, such representations and warranties
          shall be deemed to be true and correct unless the failure or failures
          of such representations and warranties to be so true and correct,
          individually or in the aggregate, and without giving effect to any
          qualification as to materiality set forth in such representations or
          warranties, has had or could reasonably be expected to have a Material
          Adverse Effect on Crompton. Witco shall have received a certificate
          signed on behalf of Crompton by the Chief Executive Officer and the

          signed on behalf of Crompton by the Chief Executive Officer and the
          Chief Financial Officer of Crompton to such effect.

          (a)      by mutual consent of Crompton and Witco;

<PAGE>

          (c) by either the Board of Directors of Crompton or the Board of
Directors of Witco if the Second Step Merger shall not have been consummated on

forth herein;

          (d) by either the Board of Directors of Crompton or the Board of
Directors of Witco (provided that the terminating party is not then in breach of

the representations or warranties set forth in this Agreement on the part of
Witco, in the case of a termination by Crompton, or Crompton or Newco, in the
case of a termination by Witco, which breach, individually or together with
other such breaches, would constitute, if occurring or continuing on the Closing
Date, the failure of the conditions set forth in Section 8.2 or 8.3, as the case

party committing such breach or by its nature or timing cannot be cured prior to

obligations, that it is necessary to (x) withdraw or modify its approval or

any proposal made by Witco since receipt of such notice to amend or modify the

Directors of Crompton has again made the determination referred to in clause

Proposal that was not solicited or encouraged by Witco or its representatives
and that did not otherwise result from the breach or a deemed breach of Section
7.3(c), (ii) the Board of Directors has determined in good faith and on a

of any of them shall have any liability of any nature whatsoever hereunder, or
in connection with the transactions contemplated hereby, except that (a) the
last sentence of Section 7.1(f), Section 9.2 and Article X shall survive any
termination of this Agreement, and (b) notwithstanding anything to the contrary

                                      -47-
<PAGE>

further approval of such stockholders, without the further approval of such
stockholders. Any agreement on the part of a party hereto to any such extension
or waiver shall be valid only if set forth in a written instrument signed on
behalf of such party, but such extension or waiver or failure to insist on
strict compliance with an obligation, covenant, agreement or condition shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure.

                                      -52-

                                                                    Exhibit 99.4

                  THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO
                   CERTAIN PROVISIONS CONTAINED HEREIN AND TO
                          RESALE RESTRICTIONS UNDER THE
                       SECURITIES ACT OF 1933, AS AMENDED


                  STOCK OPTION AGREEMENT, dated May 31, 1999, between Crompton &
Knowles, a Massachusetts corporation ("Issuer"), and Witco Corporation, a
Delaware corporation ("Grantee").

                              W I T N E S S E T H:

                  WHEREAS, Grantee and Issuer have entered into an Agreement and
Plan of Reorganization of even date herewith (the "Merger Agreement"), which
agreement has been executed by the parties hereto immediately prior to this
Stock Option Agreement (the "Agreement"); and

                  WHEREAS, as a condition to Grantee's entering into the Merger
Agreement and in consideration therefor, Issuer has agreed to grant Grantee the
Option (as hereinafter defined);

                  NOW, THEREFORE, in consideration of the foregoing and the
mutual covenants and agreements set forth herein and in the Merger Agreement,
the parties hereto agree as follows:

                  1. (a) Issuer hereby grants to Grantee an unconditional,
irrevocable option (the "Option") to purchase, subject to the terms hereof, up
to 13,025,917 fully paid and nonassessable shares of Issuer's Common Stock, par
value $.10 per share ("Common Stock"), at a price of $18.375 per share (the
"Option Price"); provided, however, that in no event shall the number of shares
of Common Stock for which this Option is exercisable exceed 19.9% of the
Issuer's issued and outstanding shares of Common Stock without giving effect to
any shares subject to or issued pursuant to the Option. The number of shares of
Common Stock that may be received upon the exercise of the Option and the Option
Price are subject to adjustment as herein set forth.

                         (b) In the event that any additional shares of Common
         Stock are either (i) issued or otherwise become outstanding after the
         date of this Agreement (other than pursuant to this Agreement) or (ii)
         redeemed, repurchased, retired or otherwise cease to be outstanding
         after the date of this Agreement, the number of shares of Common Stock
         subject to the Option shall be increased or decreased, as appropriate,
         so that, after such issuance, such number equals 19.9% of the number of
         shares of Common Stock then issued and outstanding without giving
         effect to any shares subject or issued pursuant to the Option. Nothing
         contained in this Section 1(b) or elsewhere in this Agreement shall be
         deemed to authorize Issuer or Grantee to breach any provision of the
         Merger Agreement.

                  2. (a) The Holder (as hereinafter defined) may exercise the
Option, in whole or part, and from time to time, if, but only if, a Triggering
Event (as hereinafter defined) shall have occurred prior to the occurrence of an
Exercise Termination Event (as hereinafter defined), provided that the Holder
shall have sent the written notice of such exercise (as provided in


<PAGE>

subsection (c) of this Section 2) within 60 days following such Triggering
Event. A "Triggering Event" shall mean any occurrence following which Grantee is
entitled (without any further contractual contingencies) to receive a
termination fee pursuant to Section 10.3[(b)][(c)] of the Merger Agreement. Each
of the following shall be an "Exercise Termination Event": (i) the Effective
Time (as defined in the Merger Agreement) of the Merger; (ii) termination of the
Merger Agreement in accordance with the provisions thereof if following such
termination a Triggering Event, by its terms, cannot occur; or (iii) such time
after termination of the Merger Agreement when a Triggering Event, by its terms,
cannot thereafter occur. The term "Holder" shall mean the holder or holders of
the Option.

                         (b) Issuer shall notify Grantee promptly in writing of
         the occurrence of any Triggering Event of which it has notice, it being
         understood that the giving of such notice by Issuer shall not be a
         condition to the right of the Holder to exercise the Option.

                         (c) In the event the Holder is entitled to and wishes
         to exercise the Option, it shall send to Issuer a written notice (the
         date of which being herein referred to as the "Notice Date") specifying
         (i) the total number of shares it will purchase pursuant to such
         exercise and (ii) a place and date not earlier than three business days
         nor later than 60 business days from the Notice Date for the closing of
         such purchase (the "Closing Date"); provided that if prior notification
         to or approval of any regulatory agency is required in connection with
         such purchase, the Holder shall promptly file the required notice or
         application for approval and shall expeditiously process the same and
         the period of time that otherwise would run pursuant to this sentence
         shall run instead from the date on which any required notification
         periods have expired or been terminated or such approvals have been
         obtained and any requisite waiting period or periods shall have passed.
         Any exercise of the Option shall be deemed to occur on the Notice Date
         relating thereto.

                         (d) At the closing referred to in subsection (c) of
         this Section 2, the Holder shall pay to Issuer the aggregate purchase
         price for the shares of Common Stock purchased pursuant to the exercise
         of the Option in immediately available funds by wire transfer to a bank
         account designated by Issuer, provided that failure or refusal of
         Issuer to designate such a bank account shall not preclude the Holder
         from exercising the Option.

                         (e) At such closing, simultaneously with the delivery
         of immediately available funds as provided in subsection (d) of this
         Section 2, Issuer shall deliver to the Holder a certificate or
         certificates representing the number of shares of Common Stock
         purchased by the Holder and, if the Option should be exercised in part
         only, a new Option evidencing the rights of the Holder thereof to
         purchase the balance of the shares purchasable hereunder, and the
         Holder shall deliver to Issuer this Agreement and a letter agreeing
         that the Holder will not offer to sell or otherwise dispose of such
         shares in violation of applicable law or the provisions of this
         Agreement.

                         (f) Certificates for Common Stock delivered at a
         closing hereunder may be endorsed with a restrictive legend that shall
         read substantially as follows:

                  "The transfer of the shares represented by this certificate is
                  subject to certain provisions of an agreement between the
                  registered holder hereof and Issuer and to resale restrictions
                  arising under the Securities Act of 1933, as amended. A copy


                                      -2-
<PAGE>

                  of such agreement is on file at the principal office of Issuer
                  and will be provided to the holder hereof without charge upon
                  receipt by Issuer of a written request therefor."

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 Act"), in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if the Holder shall have delivered to Issuer a copy of a letter from the staff
of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory to Issuer, to the effect that such legend is not required for
purposes of the 1933 Act; (ii) the reference to the provisions to this Agreement
in the above legend shall be removed by delivery of substitute certificate(s)
without such reference if the shares have been sold or transferred in compliance
with the provisions of this Agreement and under circumstances that do not
require the retention of such reference; and (iii) the legend shall be removed
in its entirety if the conditions in the preceding clauses (i) and (ii) are both
satisfied. In addition, such certificates shall bear any other legend as may be
required by law.

                         (g) Upon the giving by the Holder to Issuer of the
         written notice of exercise of the Option provided for under subsection
         (c) of this Section 2 and the tender of the applicable purchase price
         in immediately available funds, the Holder shall be deemed to be the
         holder of record of the shares of Common Stock issuable upon such
         exercise, notwithstanding that the stock transfer books of Issuer shall
         then be closed or that certificates representing such shares of Common
         Stock shall not then be actually delivered to the Holder. Issuer shall
         pay all expenses, and any and all United States federal, state and
         local taxes and other charges that may be payable in connection with
         the preparation, issue and delivery of stock certificates under this
         Section 2 in the name of the Holder or its assignee, transferee or
         designee.

                  3. Issuer agrees: (i) that it shall at all times maintain,
free from preemptive rights, sufficient authorized but unissued or treasury
shares of Common Stock so that the Option may be exercised without additional
authorization of Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase Common Stock; (ii)
that it will not, by charter amendment or through reorganization, consolidation,
merger, dissolution or sale of assets, or by any other voluntary act, avoid or
seek to avoid the observance or performance of any of the covenants,
stipulations or conditions to be observed or performed hereunder by Issuer;
(iii) use its reasonable best efforts to promptly to take all action as may from
time to time be required (including complying with all premerger notification,
reporting and waiting period requirements specified in 15 U.S.C. Section 18a and
regulations promulgated thereunder) in order to permit the Holder to exercise
the Option and Issuer duly and effectively to issue shares of Common Stock
pursuant hereto; and (iv) use its reasonable best efforts to promptly to take
all action provided herein to protect the rights of the Holder against dilution.

                  4. This Agreement and the Option granted hereby are
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender of this Agreement at the principal office of Issuer, for other
Agreements providing for Options of different denominations entitling the holder
thereof to purchase, on the same terms and subject to the same conditions as are
set forth herein, in the aggregate the same number of shares of Common Stock
purchasable hereunder. The terms "Agreement" and "Option" as used herein include
any Stock Option Agreements and related Options for which this Agreement (and
the Option granted hereby) may be exchanged. Upon receipt by Issuer of evidence
reasonably satisfactory to it of the loss, theft,


                                      -3-
<PAGE>

destruction or mutilation of this Agreement, and (in the case of loss, theft or
destruction) of reasonably satisfactory indemnification, and upon surrender and
cancellation of this Agreement, if mutilated, Issuer will execute and deliver a
new Agreement of like tenor and date. Any such new Agreement executed and
delivered shall constitute an additional contractual obligation on the part of
Issuer, whether or not the Agreement so lost, stolen, destroyed or mutilated
shall at any time be enforceable by anyone.

                  5. In addition to the adjustment in the number of shares of
Common Stock that are purchasable upon exercise of the Option pursuant to
Section 1 of this Agreement, the number of shares of Common Stock purchasable
upon the exercise of the Option and the Option Price shall be subject to
adjustment from time to time as provided in this Section 5. In the event of any
change in, or distributions in respect of, the Common Stock by reason of stock
dividends, split-ups, mergers, recapitalizations, combinations, subdivisions,
conversions, exchanges of shares, distributions on or in respect of the Common
Stock that would be prohibited under the terms of the Merger Agreement, or the
like, the type and number of shares of Common Stock purchasable upon exercise
hereof and the Option Price shall be appropriately adjusted in such manner as
shall fully preserve the economic benefits provided hereunder and proper
provision shall be made in any agreement governing any such transaction to
provide for such proper adjustment and the full satisfaction of the Issuer's
obligations hereunder.

                  6. Upon the occurrence of a Triggering Event that occurs prior
to an Exercise Termination Event, Issuer shall, at the request of Grantee
delivered within 60 days of such Triggering Event (whether on its own behalf or
on behalf of any subsequent holder of this Option (or part thereof) or any of
the shares of Common Stock issued pursuant hereto), promptly prepare, file and
keep current a shelf registration statement under the 1933 Act covering this
Option and any shares issued and issuable pursuant to this Option and shall use
its reasonable best efforts to cause such registration statement to become
effective and remain current in order to permit the sale or other disposition of
this Option and any shares of Common Stock issued upon total or partial exercise
of this Option ("Option Shares") in accordance with any plan of disposition
requested by Grantee. Issuer will use its reasonable best efforts to cause such
registration statement first to become effective and then to remain effective
for such period not in excess of 180 days from the day such registration
statement first becomes effective or such shorter time as may be reasonably
necessary to effect such sales or other dispositions. Grantee shall have the
right to demand two such registrations. The foregoing notwithstanding, if, at
the time of any request by Grantee for registration of the Option or Option
Shares as provided above, Issuer is in registration with respect to an
underwritten public offering of shares of Common Stock, and if in the good faith
judgment of the managing underwriter or managing underwriters, or, if none, the
sole underwriter or underwriters, of such offering the inclusion of the Holder's
Option or Option Shares would interfere with the successful marketing of the
shares of Common Stock offered by Issuer, the number of Option Shares otherwise
to be covered in the registration statement contemplated hereby may be reduced;
provided, however, that after any such required reduction the number of Option
Shares to be included in such offering for the account of the Holder shall
constitute at least 25% of the total number of shares to be sold by the Holder
and Issuer in the aggregate; and provided further, however, that if such
reduction occurs, then the Issuer shall file a registration statement for the
balance as promptly as practicable and no reduction shall thereafter occur. Each
such Holder shall provide all information reasonably requested by Issuer for
inclusion in any registration statement to be filed hereunder. If requested by
any such Holder in connection with such registration, Issuer shall become a
party to any underwriting agreement relating to the sale of such shares, but
only to the extent of obligating


                                      -4-
<PAGE>

itself in respect of representations, warranties, indemnities and other
agreements customarily included in secondary offering underwriting agreements
for the Issuer. Upon receiving any request under this Section 6 from any Holder,
Issuer agrees to send a copy thereof to any other person known to Issuer to be
entitled to registration rights under this Section 6, in each case by promptly
mailing the same, postage prepaid, to the address of record of the persons
entitled to receive such copies. Notwithstanding anything to the contrary
contained herein, in no event shall Issuer be obligated to effect more than two
registrations pursuant to this Section 6 by reason of the fact that there shall
be more than one Grantee as a result of any assignment or division of this
Agreement.

                  7. (a) Notwithstanding any other provision of this Agreement,
in no event shall the Total Option Profit (as hereinafter defined) exceed in the
aggregate $30 million.

                         (b) Notwithstanding any other provision of this
         Agreement, this Option may not be exercised for a number of shares as
         would, as of the date of exercise, result in a Notional Total Option
         Profit (as hereinafter defined) which would exceed in the aggregate $30
         million.

                         (c) As used herein, the term "Total Option Profit"
         shall mean the aggregate amount (before taxes) of the following: (i)
         (x) the amount received by Grantee pursuant to Section 15, less (y)
         Grantee's purchase price for any Option Shares, (ii) (x) the amount
         received by Grantee pursuant to the sale of Option Shares to any
         unaffiliated party, valuing any non-cash consideration at its fair
         market value, less (y) Grantee's purchase price for such Option Shares,
         and (iii) any equivalent amount with respect to the Substitute Option.

                         (d) As used herein, the term "Notional Total Option
         Profit" with respect to any number of shares of Common Stock as to
         which Grantee has delivered an exercise notice shall be the Total
         Option Profit determined as of the Notice Date assuming that the Option
         were exercised on such date for such number of shares of Common Stock
         and assuming that such shares, together with all other Option Shares
         held by Grantee and its affiliates as of such date, were sold for cash
         at the closing market price for the Common Stock as of the close of
         business on the preceding trading day (less customary brokerage
         commissions or underwriting discounts).

                  8. (a) In the event that prior to an Exercise Termination
Event, Issuer shall enter into an agreement (i) to consolidate with or merge
into any person, other than Grantee or one of its Subsidiaries, and shall not be
the continuing or surviving corporation of such consolidation or merger, (ii) to
permit any person, other than Grantee or one of its Subsidiaries, to merge into
Issuer and Issuer shall be the continuing or surviving corporation, but, in
connection with such merger, the then outstanding shares of Common Stock shall
be changed into or exchanged for stock or other securities of any other person
or cash or any other property or the then outstanding shares of Common Stock
shall after such merger represent less than 50% of the outstanding voting shares
and voting share equivalents of the merged company, or (iii) to sell or
otherwise transfer all or substantially all of its assets to any person, other
than Grantee or one of its Subsidiaries, then, and in each such case, the
agreement governing such transaction shall make proper provision so that the
Option shall, upon the consummation of any such transaction and upon the terms
and conditions set forth herein, be converted into, or exchanged


                                      -5-
<PAGE>

for, an option (the "Substitute Option"), at the election of the Holder, of
either (x) the Acquiring Corporation (as hereinafter defined) or (y) any person
that controls the Acquiring Corporation.

                         (b) The following terms have the meanings indicated:

                           (A) "Acquiring Corporation" shall mean (i) the
                  continuing or surviving corporation of a consolidation or
                  merger with Issuer (if other than Issuer), (ii) Issuer in a
                  merger in which Issuer is the continuing or surviving person,
                  and (iii) the transferee of all or substantially all of
                  Issuer's assets.

                           (B) "Substitute Common Stock" shall mean the common
                  stock issued by the issuer of the Substitute Option upon
                  exercise of the Substitute Option.

                           (3) "Assigned Value" shall mean the highest of (i)
                  the price per share of Common Stock at which a tender offer or
                  exchange offer therefor has been made, (ii) the price per
                  share of Common Stock to be paid by any third party pursuant
                  to an agreement with Issuer, (iii) the highest closing price
                  for shares of Common Stock within the immediately preceding
                  six-month period, or (iv) in the event of a sale of all or a
                  substantial portion of Issuer's assets, the sum of the price
                  paid in such sale for such assets and the current market value
                  of the remaining assets of Issuer as determined by a
                  nationally recognized investment banking firm selected by the
                  Holder and reasonably acceptable to the Issuer, divided by the
                  number of shares of Common Stock of Issuer outstanding at the
                  time of such sale.

                           (4) "Average Price" shall mean the average closing
                  price of a share of the Substitute Common Stock for the 45
                  business days immediately preceding the consolidation, merger
                  or sale in question, but in no event higher than the closing
                  price of the shares of Substitute Common Stock on the day
                  preceding such consolidation, merger or sale; provided that if
                  Issuer is the issuer of the Substitute Option, the Average
                  Price shall be computed with respect to a share of common
                  stock issued by the person merging into Issuer or by any
                  company which controls or is controlled by such person, as the
                  Holder may elect.

                         (c) The Substitute Option shall have the same terms as
         the Option, provided, that if the terms of the Substitute Option
         cannot, for legal reasons, be the same as the Option, such terms shall
         be as similar as possible and in no event less advantageous to the
         Holder. The issuer of the Substitute Option shall also enter into an
         agreement with the then Holder or Holders of the Substitute Option in
         substantially the same form as this Agreement, which shall be
         applicable to the Substitute Option.

                         (d) The Substitute Option shall be exercisable for such
         number of shares of Substitute Common Stock as is equal to the Assigned
         Value multiplied by the number of shares of Common Stock for which the
         Option is then exercisable, divided by the Average Price. The exercise
         price of the Substitute Option per share of Substitute Common Stock
         shall then be equal to the Option Price multiplied by a fraction, the
         numerator of which shall be the number of shares of Common Stock for
         which the Option is then exercisable and the denominator of which shall
         be the number of shares of Substitute Common Stock for which the
         Substitute Option is exercisable.

                                      -6-
<PAGE>

                         (e) In no event, pursuant to any of the foregoing
         paragraphs, shall the Substitute Option be exercisable for more than
         19.9% of the shares of Substitute Common Stock outstanding prior to
         exercise of the Substitute Option. In the event that the Substitute
         Option would be exercisable for more than 19.9% of the shares of
         Substitute Common Stock outstanding prior to exercise but for this
         clause (e), the issuer of the Substitute Option (the "Substitute Option
         Issuer") shall make a cash payment to Holder equal to the excess of (i)
         the value of the Substitute Option without giving effect to the
         limitation in this clause (e) over (ii) the value of the Substitute
         Option after giving effect to the limitation in this clause (e). This
         difference in value shall be determined by a nationally recognized
         investment banking firm selected by the Holder or the Owner, as the
         case may be, and reasonably acceptable to the Acquiring Corporation.

                         (f) Issuer shall not enter into any transaction
         described in subsection (a) of this Section 8 unless the Acquiring
         Corporation and any person that controls the Acquiring Corporation
         assume in writing all the obligations of Issuer hereunder.

                  9. [Intentionally Omitted]

                  10. The 60-day period for exercise of certain rights under
Sections 2, 6 and 13 shall be extended: (i) to the extent necessary to obtain
all regulatory approvals for the exercise of such rights and for the expiration
of all statutory waiting periods; and (ii) to the extent necessary to avoid
liability under Section 16(b) of the 1934 Act by reason of such exercise.

                  11. Issuer hereby represents and warrants to Grantee as
follows:

                         (a) Issuer has full corporate power and authority to
         execute and deliver this Agreement and to consummate the transactions
         contemplated hereby. The execution and delivery of this Agreement and
         the consummation of the transactions contemplated hereby have been duly
         and validly authorized by the Board of Directors of Issuer and no other
         corporate proceedings on the part of Issuer are necessary to authorize
         this Agreement or to consummate the transactions so contemplated. This
         Agreement has been duly and validly executed and delivered by Issuer.

                         (b) Issuer has taken all necessary corporate action to
         authorize and reserve and to permit it to issue, and at all times from
         the date hereof through the termination of this Agreement in accordance
         with its terms will have reserved for issuance upon the exercise of the
         Option, that number of shares of Common Stock equal to the maximum
         number of shares of Common Stock at any time and from time to time
         issuable hereunder, and all such shares, upon issuance pursuant hereto,
         will be duly authorized, validly issued, fully paid, nonassessable, and
         will be delivered free and clear of all claims, liens, encumbrance and
         security interests and not subject to any preemptive rights.

                         (c) Issuer has taken all action (including if required
         redeeming all of the Rights or amending or terminating the Rights
         Agreement) so that the entering into of this Option Agreement, the
         acquisition of shares of Common Stock hereunder and the other
         transactions contemplated hereby do not and will not result in the
         grant of any rights to any person under the Rights Agreement or enable
         or require the Rights to be exercised, distributed or triggered.

                  12. Grantee hereby represents and warrants to Issuer that:

                         (a) Grantee has all requisite corporate power and
         authority to enter into this Agreement and, subject to any approvals or
         consents referred to herein, to consummate the transactions
         contemplated hereby. The execution and delivery of this Agreement and
         the consummation of the transactions contemplated hereby have been duly
         authorized by all necessary corporate action on the part of Grantee.
         This Agreement has been duly executed and delivered by Grantee.

                         (b) The Option is not being, and any shares of Common
         Stock or other securities acquired by Grantee upon exercise of the
         Option will not be, acquired with a view to the public distribution
         thereof and will not be transferred or otherwise disposed of except in
         a transaction registered or exempt from registration under the 1933
         Act.

                  13. Neither of the parties hereto may assign any of its rights
or obligations under this Agreement or the Option created hereunder to any other
person, without the express written consent of the other party, except that in
the event a Triggering Event shall have occurred prior to an Exercise
Termination Event, Grantee, subject to the express provisions hereof, may assign
in whole or in part its rights and obligations hereunder within 90 days
following such Triggering Event (or such later period as provided in Section
10).

                  14. Each of Grantee and Issuer will use its reasonable best
efforts to make all filings with, and to obtain consents of, all third parties
and governmental authorities necessary to the consummation of the transactions
contemplated by this Agreement, including without limitation making application
to list the shares of Common Stock issuable hereunder on the New York Stock
Exchange upon official notice of issuance.

                  15. (a) At any time from and after the occurrence of a
Triggering Event, (i) following a request of the Holder, delivered prior to an
Exercise Termination Event, Issuer (or any successor thereto) shall repurchase
the Option from the Holder at a price (the "Option Repurchase Price") equal to
the amount by which (A) the Market/Offer Price (as defined below) exceeds (B)
the Option Price, multiplied by the number of shares for which this Option may
then be exercised and (ii) at the request of the owner of Option Shares from
time to time (the "Owner"), delivered within 60 days of such occurrence (or such
later period as provided in Section 10), Issuer shall repurchase such number of
the Option Shares from the Owner as the Owner shall designate at a price (the
"Option Share Repurchase Price") equal to the Market/Offer Price multiplied by
the number of Option Shares so designated. The term "Market/Offer Price" shall
mean the highest of (i) the highest price per share of Common Stock to be paid
or received in connection with or as a result of such Triggering Event
(including, in the event of a sale of all or a substantial portion of Issuer's
assets, the sum of the price paid in such sale for such assets and the current
market value of the remaining assets of Issuer as determined by a nationally
recognized investment banking firm selected by the Holder or the Owner, as the
case may be, and reasonably acceptable to the Issuer, divided by the number of
shares of Common Stock of Issuer outstanding at the time of such sale), or (ii)
the highest closing price for shares of Common Stock within the six-month period
immediately preceding the date the Holder gives notice of the required
repurchase of this Option or the Owner gives notice of the required repurchase
of Option Shares, as the case may be. In determining the Market/Offer Price, the
value of consideration other than cash shall be determined by a nationally
recognized investment


                                      -8-
<PAGE>

banking firm selected by the Holder or Owner, as the case may be, and reasonably
acceptable to the Issuer.

                         (b) The Holder and the Owner, as the case may be, may
         exercise its right to require Issuer to repurchase the Option and any
         Option Shares pursuant to this Section 15 by surrendering for such
         purpose to Issuer, at its principal office, this Agreement or
         certificates for Option Shares, as applicable, accompanied by a written
         notice or notices stating that the Holder or the Owner, as the case may
         be, elects to require Issuer to repurchase this Option and/or the
         Option Shares in accordance with the provisions of this Section 15.
         Within the latter to occur of (x) five business days after the
         surrender of the Option and/or certificates representing Option Shares
         and the receipt of such notice or notices relating thereto and (y) the
         time that is immediately prior to the occurrence of a Triggering Event,
         Issuer shall deliver or cause to be delivered to the Holder the Option
         Repurchase Price and/or to the Owner the Option Share Repurchase Price
         therefor or the portion thereof, if any, that Issuer is not then
         prohibited under applicable law and regulation from so delivering.

                         (c) To the extent that Issuer is prohibited under
         applicable law or regulation from repurchasing the Option and/or the
         Option Shares in full, Issuer shall immediately so notify the Holder
         and/or the Owner and thereafter deliver or cause to be delivered, from
         time to time, to the Holder and/or the Owner, as appropriate, the
         portion of the Option Repurchase Price and the Option Share Repurchase
         Price, respectively, that it is no longer prohibited from delivering,
         within five business days after the date on which Issuer is no longer
         so prohibited; provided, however, that if Issuer at any time after
         delivery of a notice of repurchase pursuant to paragraph (b) of this
         Section 15 is prohibited under applicable law or regulation from
         delivering to the Holder and/or the Owner, as appropriate, the Option
         Repurchase Price and the Option Share Repurchase Price, respectively,
         in full (and Issuer hereby undertakes to use its reasonable best
         efforts to obtain all required regulatory and legal approvals and to
         file any required notices, in each case as promptly as practicable in
         order to accomplish such repurchase), the Holder or Owner may revoke
         its notice of repurchase of the Option or the Option Shares either in
         whole or to the extent of the prohibition, whereupon, in the latter
         case, Issuer shall promptly (i) deliver to the Holder and/or the Owner,
         as appropriate, that portion of the Option Repurchase Price or the
         Option Share Repurchase Price that Issuer is not prohibited from
         delivering; and (ii) deliver, as appropriate, either (A) to the Holder,
         a new Stock Option Agreement evidencing the right of the Holder to
         purchase that number of shares of Common Stock obtained by multiplying
         the number of shares of Common Stock for which the surrendered Stock
         Option Agreement was exercisable at the time of delivery of the notice
         of repurchase by a fraction, the numerator of which is the Option
         Repurchase Price less the portion thereof theretofore delivered to the
         Holder and the denominator of which is the Option Repurchase Price, or
         (B) to the Owner, a certificate for the Option Shares it is then so
         prohibited from repurchasing.

                         (d) The parties hereto agree that Issuer's obligations
         to repurchase the Option or Option Shares under this Section 15 shall
         not terminate upon the occurrence of an Exercise Termination Event
         unless no Triggering Event shall have occurred prior to the occurrence
         of an Exercise Termination Event.

                                      -9-
<PAGE>

                         (e) The Holder and any Owner shall have rights
         substantially identical to those set forth in paragraphs (a), (b), (c)
         and (d) of this Section 15 with respect to the Substitute Option, the
         Substitute Common Stock and the Substitute Option Issuer.


                  16. The parties hereto acknowledge that damages would be an
inadequate remedy for a breach of this Agreement by either party hereto and that
the obligations of the parties hereto shall be enforceable by either party
hereto through injunctive or other equitable relief.

                  17. If any term, provision, covenant or restriction contained
in this Agreement is held by a court or a federal or state regulatory agency of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions and covenants and restrictions contained in this Agreement
shall remain in full force and effect, and shall in no way be affected, impaired
or invalidated. If for any reason such court or regulatory agency determines
that the Holder is not permitted to acquire, or Issuer is not permitted to
repurchase pursuant to Section 15, the full number of shares of Common Stock
provided in Section 1(a) hereof (as adjusted pursuant to Section 1(b) or 5
hereof), it is the express intention of Issuer to allow the Holder to acquire or
to require Issuer to repurchase such lesser number of shares as may be
permissible, without any amendment or modification hereof.

                  18. All notices, requests, claims, demands and other
communications hereunder shall be deemed to have been duly given when delivered
in person, by cable, telegram, telecopy or telex, or by registered or certified
mail (postage prepaid, return receipt requested) at the respective addresses of
the parties set forth in the Merger Agreement.

                  19. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof
(except to the extent that mandatory provisions of federal or state law apply).

                  20. This Agreement may be executed in two counterparts, each
of which shall be deemed to be an original, but all of which shall constitute
one and the same agreement.

                  21. Except as otherwise expressly provided herein, each of the
parties hereto shall bear and pay all costs and expenses incurred by it or on
its behalf in connection with the transactions contemplated hereunder, including
fees and expenses of its own financial consultants, investment bankers,
accountants and counsel.

                  22. Except as otherwise expressly provided herein or in the
Merger Agreement, this Agreement contains the entire agreement between the
parties with respect to the transactions contemplated hereunder and supersedes
all prior arrangements or understandings with respect thereof, written or oral.
The terms and conditions of this Agreement shall inure to the benefit of and be
binding upon the parties hereto and their respective successors and permitted
assigns. Nothing in this Agreement, expressed or implied, is intended to confer
upon any party, other than the parties hereto, and their respective successors
and permitted assigns, any rights, remedies, obligations or liabilities under or
by reason of this Agreement, except as expressly provided herein.

                  THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO
                   CERTAIN PROVISIONS CONTAINED HEREIN AND TO
                          RESALE RESTRICTIONS UNDER THE
                       SECURITIES ACT OF 1933, AS AMENDED


                  STOCK OPTION AGREEMENT, dated May 31, 1999, between Witco
Corporation, a Delaware corporation ("Issuer"), and Crompton & Knowles
Corporation, a Massachusetts corporation ("Grantee").

                              W I T N E S S E T H:

                  WHEREAS, Grantee and Issuer have entered into an Agreement and
Plan of Reorganization of even date herewith (the "Merger Agreement"), which
agreement has been executed by the parties hereto immediately prior to this
Stock Option Agreement (the "Agreement"); and

                  WHEREAS, as a condition to Grantee's entering into the Merger
Agreement and in consideration therefor, Issuer has agreed to grant Grantee the
Option (as hereinafter defined);

                  NOW, THEREFORE, in consideration of the foregoing and the
mutual covenants and agreements set forth herein and in the Merger Agreement,
the parties hereto agree as follows:

                  1. (a) Issuer hereby grants to Grantee an unconditional,
irrevocable option (the "Option") to purchase, subject to the terms hereof, up
to 11,471,159 fully paid and nonassessable shares of Issuer's Common Stock, par
value $5.00 per share ("Common Stock"), at a price of $17.50 per share (the
"Option Price"); provided, however, that in no event shall the number of shares
of Common Stock for which this Option is exercisable exceed 19.9% of the
Issuer's issued and outstanding shares of Common Stock without giving effect to
any shares subject to or issued pursuant to the Option. The number of shares of
Common Stock that may be received upon the exercise of the Option and the Option
Price are subject to adjustment as herein set forth.

                         (b)  In the event that any additional shares of Common
         Stock are either (i) issued or otherwise become outstanding after the
         date of this Agreement (other than pursuant to this Agreement) or (ii)
         redeemed, repurchased, retired or otherwise cease to be outstanding
         after the date of this Agreement, the number of shares of Common Stock
         subject to the Option shall be increased or decreased, as appropriate,
         so that, after such issuance, such number equals 19.9% of the number of
         shares of Common Stock then issued and outstanding without giving
         effect to any shares subject or issued pursuant to the Option. Nothing
         contained in this Section 1(b) or elsewhere in this Agreement shall be
         deemed to authorize Issuer or Grantee to breach any provision of the
         Merger Agreement.

                  2. (a) The Holder (as hereinafter defined) may exercise the
Option, in whole or part, and from time to time, if, but only if, a Triggering
Event (as hereinafter defined) shall have occurred prior to the occurrence of an
Exercise Termination Event (as hereinafter defined), provided that the Holder
shall have sent the written notice of such exercise (as provided in

<PAGE>

subsection (c) of this Section 2) within 60 days following such Triggering
Event. A "Triggering Event" shall mean any occurrence following which Grantee is
entitled (without any further contractual contingencies) to receive a
termination fee pursuant to Section 10.3[(b)][(c)] of the Merger Agreement. Each
of the following shall be an "Exercise Termination Event": (i) the Effective
Time (as defined in the Merger Agreement) of the Merger; (ii) termination of the
Merger Agreement in accordance with the provisions thereof if following such
termination a Triggering Event, by its terms, cannot occur; or (iii) such time
after termination of the Merger Agreement when a Triggering Event, by its terms,
cannot thereafter occur. The term "Holder" shall mean the holder or holders of
the Option.

                         (b) Issuer shall notify Grantee promptly in writing of
         the occurrence of any Triggering Event of which it has notice, it being
         understood that the giving of such notice by Issuer shall not be a
         condition to the right of the Holder to exercise the Option.

                         (c) In the event the Holder is entitled to and wishes
         to exercise the Option, it shall send to Issuer a written notice (the
         date of which being herein referred to as the "Notice Date") specifying
         (i) the total number of shares it will purchase pursuant to such
         exercise and (ii) a place and date not earlier than three business days
         nor later than 60 business days from the Notice Date for the closing of
         such purchase (the "Closing Date"); provided that if prior notification
         to or approval of any regulatory agency is required in connection with
         such purchase, the Holder shall promptly file the required notice or
         application for approval and shall expeditiously process the same and
         the period of time that otherwise would run pursuant to this sentence
         shall run instead from the date on which any required notification
         periods have expired or been terminated or such approvals have been
         obtained and any requisite waiting period or periods shall have passed.
         Any exercise of the Option shall be deemed to occur on the Notice Date
         relating thereto.

                         (d) At the closing referred to in subsection (c) of
         this Section 2, the Holder shall pay to Issuer the aggregate purchase
         price for the shares of Common Stock purchased pursuant to the exercise
         of the Option in immediately available funds by wire transfer to a bank
         account designated by Issuer, provided that failure or refusal of
         Issuer to designate such a bank account shall not preclude the Holder
         from exercising the Option.

                         (e) At such closing, simultaneously with the delivery
         of immediately available funds as provided in subsection (d) of this
         Section 2, Issuer shall deliver to the Holder a certificate or
         certificates representing the number of shares of Common Stock
         purchased by the Holder and, if the Option should be exercised in part
         only, a new Option evidencing the rights of the Holder thereof to
         purchase the balance of the shares purchasable hereunder, and the
         Holder shall deliver to Issuer this Agreement and a letter agreeing
         that the Holder will not offer to sell or otherwise dispose of such
         shares in violation of applicable law or the provisions of this
         Agreement.

                         (f) Certificates for Common Stock delivered at a
         closing hereunder may be endorsed with a restrictive legend that shall
         read substantially as follows:

                  "The transfer of the shares represented by this certificate is
                  subject to certain provisions of an agreement between the
                  registered holder hereof and Issuer and to resale restrictions
                  arising under the Securities Act of 1933, as amended.


                                      -2-
<PAGE>

                  A copy of such agreement is on file at the principal office of
                  Issuer and will be provided to the holder hereof without
                  charge upon receipt by Issuer of a written request therefor."

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 Act"), in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if the Holder shall have delivered to Issuer a copy of a letter from the staff
of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory to Issuer, to the effect that such legend is not required for
purposes of the 1933 Act; (ii) the reference to the provisions to this Agreement
in the above legend shall be removed by delivery of substitute certificate(s)
without such reference if the shares have been sold or transferred in compliance
with the provisions of this Agreement and under circumstances that do not
require the retention of such reference; and (iii) the legend shall be removed
in its entirety if the conditions in the preceding clauses (i) and (ii) are both
satisfied. In addition, such certificates shall bear any other legend as may be
required by law.

                         (g) Upon the giving by the Holder to Issuer of the
         written notice of exercise of the Option provided for under subsection
         (c) of this Section 2 and the tender of the applicable purchase price
         in immediately available funds, the Holder shall be deemed to be the
         holder of record of the shares of Common Stock issuable upon such
         exercise, notwithstanding that the stock transfer books of Issuer shall
         then be closed or that certificates representing such shares of Common
         Stock shall not then be actually delivered to the Holder. Issuer shall
         pay all expenses, and any and all United States federal, state and
         local taxes and other charges that may be payable in connection with
         the preparation, issue and delivery of stock certificates under this
         Section 2 in the name of the Holder or its assignee, transferee or
         designee.

                  3. Issuer agrees: (i) that it shall at all times maintain,
free from preemptive rights, sufficient authorized but unissued or treasury
shares of Common Stock so that the Option may be exercised without additional
authorization of Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase Common Stock; (ii)
that it will not, by charter amendment or through reorganization, consolidation,
merger, dissolution or sale of assets, or by any other voluntary act, avoid or
seek to avoid the observance or performance of any of the covenants,
stipulations or conditions to be observed or performed hereunder by Issuer;
(iii) use its reasonable best efforts to promptly to take all action as may from
time to time be required (including complying with all premerger notification,
reporting and waiting period requirements specified in 15 U.S.C. Section 18a and
regulations promulgated thereunder) in order to permit the Holder to exercise
the Option and Issuer duly and effectively to issue shares of Common Stock
pursuant hereto; and (iv) use its reasonable best efforts to promptly to take
all action provided herein to protect the rights of the Holder against dilution.

                  4. This Agreement and the Option granted hereby are
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender of this Agreement at the principal office of Issuer, for other
Agreements providing for Options of different denominations entitling the holder
thereof to purchase, on the same terms and subject to the same conditions as are
set forth herein, in the aggregate the same number of shares of Common Stock
purchasable hereunder. The terms "Agreement" and "Option" as used herein include
any Stock Option Agreements and related Options for which this Agreement (and
the Option granted hereby) may be exchanged. Upon receipt by Issuer of evidence
reasonably satisfactory to it of the loss, theft,


                                      -3-
<PAGE>

destruction or mutilation of this Agreement, and (in the case of loss, theft or
destruction) of reasonably satisfactory indemnification, and upon surrender and
cancellation of this Agreement, if mutilated, Issuer will execute and deliver a
new Agreement of like tenor and date. Any such new Agreement executed and
delivered shall constitute an additional contractual obligation on the part of
Issuer, whether or not the Agreement so lost, stolen, destroyed or mutilated
shall at any time be enforceable by anyone.

                  5. In addition to the adjustment in the number of shares of
Common Stock that are purchasable upon exercise of the Option pursuant to
Section 1 of this Agreement, the number of shares of Common Stock purchasable
upon the exercise of the Option and the Option Price shall be subject to
adjustment from time to time as provided in this Section 5. In the event of any
change in, or distributions in respect of, the Common Stock by reason of stock
dividends, split-ups, mergers, recapitalizations, combinations, subdivisions,
conversions, exchanges of shares, distributions on or in respect of the Common
Stock that would be prohibited under the terms of the Merger Agreement, or the
like, the type and number of shares of Common Stock purchasable upon exercise
hereof and the Option Price shall be appropriately adjusted in such manner as
shall fully preserve the economic benefits provided hereunder and proper
provision shall be made in any agreement governing any such transaction to
provide for such proper adjustment and the full satisfaction of the Issuer's
obligations hereunder.

                  6. Upon the occurrence of a Triggering Event that occurs prior
to an Exercise Termination Event, Issuer shall, at the request of Grantee
delivered within 60 days of such Triggering Event (whether on its own behalf or
on behalf of any subsequent holder of this Option (or part thereof) or any of
the shares of Common Stock issued pursuant hereto), promptly prepare, file and
keep current a shelf registration statement under the 1933 Act covering this
Option and any shares issued and issuable pursuant to this Option and shall use
its reasonable best efforts to cause such registration statement to become
effective and remain current in order to permit the sale or other disposition of
this Option and any shares of Common Stock issued upon total or partial exercise
of this Option ("Option Shares") in accordance with any plan of disposition
requested by Grantee. Issuer will use its reasonable best efforts to cause such
registration statement first to become effective and then to remain effective
for such period not in excess of 180 days from the day such registration
statement first becomes effective or such shorter time as may be reasonably
necessary to effect such sales or other dispositions. Grantee shall have the
right to demand two such registrations. The foregoing notwithstanding, if, at
the time of any request by Grantee for registration of the Option or Option
Shares as provided above, Issuer is in registration with respect to an
underwritten public offering of shares of Common Stock, and if in the good faith
judgment of the managing underwriter or managing underwriters, or, if none, the
sole underwriter or underwriters, of such offering the inclusion of the Holder's
Option or Option Shares would interfere with the successful marketing of the
shares of Common Stock offered by Issuer, the number of Option Shares otherwise
to be covered in the registration statement contemplated hereby may be reduced;
provided, however, that after any such required reduction the number of Option
Shares to be included in such offering for the account of the Holder shall
constitute at least 25% of the total number of shares to be sold by the Holder
and Issuer in the aggregate; and provided further, however, that if such
reduction occurs, then the Issuer shall file a registration statement for the
balance as promptly as practicable and no reduction shall thereafter occur. Each
such Holder shall provide all information reasonably requested by Issuer for
inclusion in any registration statement to be filed hereunder. If requested by
any such Holder in connection with such registration, Issuer shall become a
party to any underwriting agreement relating to the sale of such shares, but
only to the extent of obligating


                                      -4-
<PAGE>

itself in respect of representations, warranties, indemnities and other
agreements customarily included in secondary offering underwriting agreements
for the Issuer. Upon receiving any request under this Section 6 from any Holder,
Issuer agrees to send a copy thereof to any other person known to Issuer to be
entitled to registration rights under this Section 6, in each case by promptly
mailing the same, postage prepaid, to the address of record of the persons
entitled to receive such copies. Notwithstanding anything to the contrary
contained herein, in no event shall Issuer be obligated to effect more than two
registrations pursuant to this Section 6 by reason of the fact that there shall
be more than one Grantee as a result of any assignment or division of this
Agreement.

                  7.  (a) Notwithstanding any other provision of this Agreement,
in no event shall the Total Option Profit (as hereinafter defined) exceed in the
aggregate $30 million.

                         (b) Notwithstanding any other provision of this
         Agreement, this Option may not be exercised for a number of shares as
         would, as of the date of exercise, result in a Notional Total Option
         Profit (as hereinafter defined) which would exceed in the aggregate $30
         million.

                         (c) As used herein, the term "Total Option Profit"
         shall mean the aggregate amount (before taxes) of the following: (i)
         (x) the amount received by Grantee pursuant to Section 15, less (y)
         Grantee's purchase price for any Option Shares, (ii) (x) the amount
         received by Grantee pursuant to the sale of Option Shares to any
         unaffiliated party, valuing any non-cash consideration at its fair
         market value, less (y) Grantee's purchase price for such Option Shares,
         and (iii) any equivalent amount with respect to the Substitute Option.

                         (d) As used herein, the term "Notional Total Option
         Profit" with respect to any number of shares of Common Stock as to
         which Grantee has delivered an exercise notice shall be the Total
         Option Profit determined as of the Notice Date assuming that the Option
         were exercised on such date for such number of shares of Common Stock
         and assuming that such shares, together with all other Option Shares
         held by Grantee and its affiliates as of such date, were sold for cash
         at the closing market price for the Common Stock as of the close of
         business on the preceding trading day (less customary brokerage
         commissions or underwriting discounts).

                  8. (a) In the event that prior to an Exercise Termination
Event, Issuer shall enter into an agreement (i) to consolidate with or merge
into any person, other than Grantee or one of its Subsidiaries, and shall not be
the continuing or surviving corporation of such consolidation or merger, (ii) to
permit any person, other than Grantee or one of its Subsidiaries, to merge into
Issuer and Issuer shall be the continuing or surviving corporation, but, in
connection with such merger, the then outstanding shares of Common Stock shall
be changed into or exchanged for stock or other securities of any other person
or cash or any other property or the then outstanding shares of Common Stock
shall after such merger represent less than 50% of the outstanding voting shares
and voting share equivalents of the merged company, or (iii) to sell or
otherwise transfer all or substantially all of its assets to any person, other
than Grantee or one of its Subsidiaries, then, and in each such case, the
agreement governing such transaction shall make proper provision so that the
Option shall, upon the consummation of any such transaction and upon the terms
and conditions set forth herein, be converted into, or exchanged


                                      -5-
<PAGE>

for, an option (the "Substitute Option"), at the election of the Holder, of
either (x) the Acquiring Corporation (as hereinafter defined) or (y) any person
that controls the Acquiring Corporation.

                         (b) The following terms have the meanings indicated:

                           (A) "Acquiring Corporation" shall mean (i) the
                  continuing or surviving corporation of a consolidation or
                  merger with Issuer (if other than Issuer), (ii) Issuer in a
                  merger in which Issuer is the continuing or surviving person,
                  and (iii) the transferee of all or substantially all of
                  Issuer's assets.

                           (B) "Substitute Common Stock" shall mean the common
                  stock issued by the issuer of the Substitute Option upon
                  exercise of the Substitute Option.

                           (3) "Assigned Value" shall mean the highest of (i)
                  the price per share of Common Stock at which a tender offer or
                  exchange offer therefor has been made, (ii) the price per
                  share of Common Stock to be paid by any third party pursuant
                  to an agreement with Issuer, (iii) the highest closing price
                  for shares of Common Stock within the immediately preceding
                  six-month period, or (iv) in the event of a sale of all or a
                  substantial portion of Issuer's assets, the sum of the price
                  paid in such sale for such assets and the current market value
                  of the remaining assets of Issuer as determined by a
                  nationally recognized investment banking firm selected by the
                  Holder and reasonably acceptable to the Issuer, divided by the
                  number of shares of Common Stock of Issuer outstanding at the
                  time of such sale.

                           (4) "Average Price" shall mean the average closing
                  price of a share of the Substitute Common Stock for the 45
                  business days immediately preceding the consolidation, merger
                  or sale in question, but in no event higher than the closing
                  price of the shares of Substitute Common Stock on the day
                  preceding such consolidation, merger or sale; provided that if
                  Issuer is the issuer of the Substitute Option, the Average
                  Price shall be computed with respect to a share of common
                  stock issued by the person merging into Issuer or by any
                  company which controls or is controlled by such person, as the
                  Holder may elect.

                         (c) The Substitute Option shall have the same terms as
         the Option, provided, that if the terms of the Substitute Option
         cannot, for legal reasons, be the same as the Option, such terms shall
         be as similar as possible and in no event less advantageous to the
         Holder. The issuer of the Substitute Option shall also enter into an
         agreement with the then Holder or Holders of the Substitute Option in
         substantially the same form as this Agreement, which shall be
         applicable to the Substitute Option.

                         (d) The Substitute Option shall be exercisable for such
         number of shares of Substitute Common Stock as is equal to the Assigned
         Value multiplied by the number of shares of Common Stock for which the
         Option is then exercisable, divided by the Average Price. The exercise
         price of the Substitute Option per share of Substitute Common Stock
         shall then be equal to the Option Price multiplied by a fraction, the
         numerator of which shall be the number of shares of Common Stock for
         which the Option is then exercisable and the denominator of which shall
         be the number of shares of Substitute Common Stock for which the
         Substitute Option is exercisable.

                                      -6-
<PAGE>

                         (e) In no event, pursuant to any of the foregoing
         paragraphs, shall the Substitute Option be exercisable for more than
         19.9% of the shares of Substitute Common Stock outstanding prior to
         exercise of the Substitute Option. In the event that the Substitute
         Option would be exercisable for more than 19.9% of the shares of
         Substitute Common Stock outstanding prior to exercise but for this
         clause (e), the issuer of the Substitute Option (the "Substitute Option
         Issuer") shall make a cash payment to Holder equal to the excess of (i)
         the value of the Substitute Option without giving effect to the
         limitation in this clause (e) over (ii) the value of the Substitute
         Option after giving effect to the limitation in this clause (e). This
         difference in value shall be determined by a nationally recognized
         investment banking firm selected by the Holder or the Owner, as the
         case may be, and reasonably acceptable to the Acquiring Corporation.

                         (f) Issuer shall not enter into any transaction
         described in subsection (a) of this Section 8 unless the Acquiring
         Corporation and any person that controls the Acquiring Corporation
         assume in writing all the obligations of Issuer hereunder.

                  9. [Intentionally Omitted]

                  10. The 60-day period for exercise of certain rights under
Sections 2, 6 and 13 shall be extended: (i) to the extent necessary to obtain
all regulatory approvals for the exercise of such rights and for the expiration
of all statutory waiting periods; and (ii) to the extent necessary to avoid
liability under Section 16(b) of the 1934 Act by reason of such exercise.

                  11. Issuer hereby represents and warrants to Grantee as
follows:

                         (a) Issuer has full corporate power and authority to
         execute and deliver this Agreement and to consummate the transactions
         contemplated hereby. The execution and delivery of this Agreement and
         the consummation of the transactions contemplated hereby have been duly
         and validly authorized by the Board of Directors of Issuer and no other
         corporate proceedings on the part of Issuer are necessary to authorize
         this Agreement or to consummate the transactions so contemplated. This
         Agreement has been duly and validly executed and delivered by Issuer.

                         (b) Issuer has taken all necessary corporate action to
         authorize and reserve and to permit it to issue, and at all times from
         the date hereof through the termination of this Agreement in accordance
         with its terms will have reserved for issuance upon the exercise of the
         Option, that number of shares of Common Stock equal to the maximum
         number of shares of Common Stock at any time and from time to time
         issuable hereunder, and all such shares, upon issuance pursuant hereto,
         will be duly authorized, validly issued, fully paid, nonassessable, and
         will be delivered free and clear of all claims, liens, encumbrance and
         security interests and not subject to any preemptive rights.

                         (c) Issuer has taken all action (including if required
         redeeming all of the Rights or amending or terminating the Rights
         Agreement) so that the entering into of this Option Agreement, the
         acquisition of shares of Common Stock hereunder and the other
         transactions contemplated hereby do not and will not result in the
         grant of any rights to any person under the Rights Agreement or enable
         or require the Rights to be exercised, distributed or triggered.

                                      -7-

                  12. Grantee hereby represents and warrants to Issuer that:

                         (a) Grantee has all requisite corporate power and
         authority to enter into this Agreement and, subject to any approvals or
         consents referred to herein, to consummate the transactions
         contemplated hereby. The execution and delivery of this Agreement and
         the consummation of the transactions contemplated hereby have been duly
         authorized by all necessary corporate action on the part of Grantee.
         This Agreement has been duly executed and delivered by Grantee.

                         (b) The Option is not being, and any shares of Common
         Stock or other securities acquired by Grantee upon exercise of the
         Option will not be, acquired with a view to the public distribution
         thereof and will not be transferred or otherwise disposed of except in
         a transaction registered or exempt from registration under the 1933
         Act.

                  13. Neither of the parties hereto may assign any of its rights
or obligations under this Agreement or the Option created hereunder to any other
person, without the express written consent of the other party, except that in
the event a Triggering Event shall have occurred prior to an Exercise
Termination Event, Grantee, subject to the express provisions hereof, may assign
in whole or in part its rights and obligations hereunder within 90 days
following such Triggering Event (or such later period as provided in Section
10).

                  14. Each of Grantee and Issuer will use its reasonable best
efforts to make all filings with, and to obtain consents of, all third parties
and governmental authorities necessary to the consummation of the transactions
contemplated by this Agreement, including without limitation making application
to list the shares of Common Stock issuable hereunder on the New York Stock
Exchange upon official notice of issuance.

                  15. (a) At any time from and after the occurrence of a
Triggering Event, (i) following a request of the Holder, delivered prior to an
Exercise Termination Event, Issuer (or any successor thereto) shall repurchase
the Option from the Holder at a price (the "Option Repurchase Price") equal to
the amount by which (A) the Market/Offer Price (as defined below) exceeds (B)
the Option Price, multiplied by the number of shares for which this Option may
then be exercised and (ii) at the request of the owner of Option Shares from
time to time (the "Owner"), delivered within 60 days of such occurrence (or such
later period as provided in Section 10), Issuer shall repurchase such number of
the Option Shares from the Owner as the Owner shall designate at a price (the
"Option Share Repurchase Price") equal to the Market/Offer Price multiplied by
the number of Option Shares so designated. The term "Market/Offer Price" shall
mean the highest of (i) the highest price per share of Common Stock to be paid
or received in connection with or as a result of such Triggering Event
(including, in the event of a sale of all or a substantial portion of Issuer's
assets, the sum of the price paid in such sale for such assets and the current
market value of the remaining assets of Issuer as determined by a nationally
recognized investment banking firm selected by the Holder or the Owner, as the
case may be, and reasonably acceptable to the Issuer, divided by the number of
shares of Common Stock of Issuer outstanding at the time of such sale), or (ii)
the highest closing price for shares of Common Stock within the six-month period
immediately preceding the date the Holder gives notice of the required
repurchase of this Option or the Owner gives notice of the required repurchase
of Option Shares, as the case may be. In determining the Market/Offer Price, the
value of consideration other than cash shall be determined by a nationally
recognized investment


                                      -8-
<PAGE>

banking firm selected by the Holder or Owner, as the case may be, and reasonably
acceptable to the Issuer.

                         (b) The Holder and the Owner, as the case may be, may
         exercise its right to require Issuer to repurchase the Option and any
         Option Shares pursuant to this Section 15 by surrendering for such
         purpose to Issuer, at its principal office, this Agreement or
         certificates for Option Shares, as applicable, accompanied by a written
         notice or notices stating that the Holder or the Owner, as the case may
         be, elects to require Issuer to repurchase this Option and/or the
         Option Shares in accordance with the provisions of this Section 15.
         Within the latter to occur of (x) five business days after the
         surrender of the Option and/or certificates representing Option Shares
         and the receipt of such notice or notices relating thereto and (y) the
         time that is immediately prior to the occurrence of a Triggering Event,
         Issuer shall deliver or cause to be delivered to the Holder the Option
         Repurchase Price and/or to the Owner the Option Share Repurchase Price
         therefor or the portion thereof, if any, that Issuer is not then
         prohibited under applicable law and regulation from so delivering.

                         (c) To the extent that Issuer is prohibited under
         applicable law or regulation from repurchasing the Option and/or the
         Option Shares in full, Issuer shall immediately so notify the Holder
         and/or the Owner and thereafter deliver or cause to be delivered, from
         time to time, to the Holder and/or the Owner, as appropriate, the
         portion of the Option Repurchase Price and the Option Share Repurchase
         Price, respectively, that it is no longer prohibited from delivering,
         within five business days after the date on which Issuer is no longer
         so prohibited; provided, however, that if Issuer at any time after
         delivery of a notice of repurchase pursuant to paragraph (b) of this
         Section 15 is prohibited under applicable law or regulation from
         delivering to the Holder and/or the Owner, as appropriate, the Option
         Repurchase Price and the Option Share Repurchase Price, respectively,
         in full (and Issuer hereby undertakes to use its reasonable best
         efforts to obtain all required regulatory and legal approvals and to
         file any required notices, in each case as promptly as practicable in
         order to accomplish such repurchase), the Holder or Owner may revoke
         its notice of repurchase of the Option or the Option Shares either in
         whole or to the extent of the prohibition, whereupon, in the latter
         case, Issuer shall promptly (i) deliver to the Holder and/or the Owner,
         as appropriate, that portion of the Option Repurchase Price or the
         Option Share Repurchase Price that Issuer is not prohibited from
         delivering; and (ii) deliver, as appropriate, either (A) to the Holder,
         a new Stock Option Agreement evidencing the right of the Holder to
         purchase that number of shares of Common Stock obtained by multiplying
         the number of shares of Common Stock for which the surrendered Stock
         Option Agreement was exercisable at the time of delivery of the notice
         of repurchase by a fraction, the numerator of which is the Option
         Repurchase Price less the portion thereof theretofore delivered to the
         Holder and the denominator of which is the Option Repurchase Price, or
         (B) to the Owner, a certificate for the Option Shares it is then so
         prohibited from repurchasing.

                         (d) The parties hereto agree that Issuer's obligations
         to repurchase the Option or Option Shares under this Section 15 shall
         not terminate upon the occurrence of an Exercise Termination Event
         unless no Triggering Event shall have occurred prior to the occurrence
         of an Exercise Termination Event.

<PAGE>

                         (e) The Holder and any Owner shall have rights
         substantially identical to those set forth in paragraphs (a), (b), (c)
         and (d) of this Section 15 with respect to the Substitute Option, the
         Substitute Common Stock and the Substitute Option Issuer.


                  16. The parties hereto acknowledge that damages would be an
inadequate remedy for a breach of this Agreement by either party hereto and that
the obligations of the parties hereto shall be enforceable by either party
hereto through injunctive or other equitable relief.

                  17. If any term, provision, covenant or restriction contained
in this Agreement is held by a court or a federal or state regulatory agency of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions and covenants and restrictions contained in this Agreement
shall remain in full force and effect, and shall in no way be affected, impaired
or invalidated. If for any reason such court or regulatory agency determines
that the Holder is not permitted to acquire, or Issuer is not permitted to
repurchase pursuant to Section 15, the full number of shares of Common Stock
provided in Section 1(a) hereof (as adjusted pursuant to Section 1(b) or 5
hereof), it is the express intention of Issuer to allow the Holder to acquire or
to require Issuer to repurchase such lesser number of shares as may be
permissible, without any amendment or modification hereof.

                  18. All notices, requests, claims, demands and other
communications hereunder shall be deemed to have been duly given when delivered
in person, by cable, telegram, telecopy or telex, or by registered or certified
mail (postage prepaid, return receipt requested) at the respective addresses of
the parties set forth in the Merger Agreement.

                  19. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof
(except to the extent that mandatory provisions of federal or state law apply).

                  20. This Agreement may be executed in two counterparts, each
of which shall be deemed to be an original, but all of which shall constitute
one and the same agreement.

                  21. Except as otherwise expressly provided herein, each of the
parties hereto shall bear and pay all costs and expenses incurred by it or on
its behalf in connection with the transactions contemplated hereunder, including
fees and expenses of its own financial consultants, investment bankers,
accountants and counsel.

                  22. Except as otherwise expressly provided herein or in the
Merger Agreement, this Agreement contains the entire agreement between the
parties with respect to the transactions contemplated hereunder and supersedes
all prior arrangements or understandings with respect thereof, written or oral.
The terms and conditions of this Agreement shall inure to the benefit of and be
binding upon the parties hereto and their respective successors and permitted
assigns. Nothing in this Agreement, expressed or implied, is intended to confer
upon any party, other than the parties hereto, and their respective successors
and permitted assigns, any rights, remedies, obligations or liabilities under or
by reason of this Agreement, except as expressly provided herein.
