Investor and the Investor agrees that it will purchase from the Company, at the

and the Other Investors are hereinafter referred to collectively as the
"Investors."

whether this subscription has been accepted or rejected.  The Investor further
understands and agrees that the Company reserves the right to accept or reject
subscriptions (in whole or in part), and that this subscription may be accepted

          (b)  The Investor acknowledges and agrees that the Aggregate Purchase

          (c)  SUBSEQUENT SALE.    During the period beginning on the date
hereof and continuing until the Closing, the Investor will not offer, sell,
contract to sell or otherwise dispose of, or bid for, purchase, contract to

without the prior written consent of the Company.

     3.   REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS.

          The Investor represents, warrants and agrees as follows:

               (1)  The Investor has received and reviewed a copy of the
Memorandum, and all appendices and supplements (if any) thereto, relating to the
Shares and understands that no Person has been authorized to give any
information or to make any representations that were not contained in the
Memorandum, and the Investor has not relied on any such other information or
representations in making a decision to purchase the Investor Shares.  The
Investor has had access to such financial and other information and has had the

                                          2
<PAGE>

opportunity to ask questions and receive answers as deemed necessary in respect
of the decision to purchase the Shares, and has consulted with advisors
concerning the proposed investment in the Company.  The Investor understands
that an investment in the Company involves a high degree of risk for the
reasons, among others, set forth under the caption "RISK FACTORS" in the
Memorandum.

               (2)   The Investor has made an investigation as to whether or not
to invest in the Shares and, in making the decision to so invest, is not in any
way relying on the fact that any other Person has decided to invest in the
Shares.

               (3)   The Investor represents that the Investor (or, if
applicable, each managed account on whose behalf the Investor Shares are being
purchased by such Investor) is a sophisticated investor or is an "accredited
investor" as defined in Rule 501 under the Securities Act of 1933, as amended
(the "Securities Act"), as certified by the Investor pursuant to the Investor
Questionnaire attached hereto as ANNEX I.  The Investor further represents that
the Investor (or, if applicable, each managed account on whose behalf the
Investor Shares are being purchased) has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risk of an investment in the Shares and can bear the economic risk of loss of
the entire investment in the Shares being purchased.

               (4)  The Investor understands and expressly acknowledges and
agrees that none of the Shares has been, or will be, registered or qualified
under the Securities Act, or under any applicable securities laws of any State
of the United States ("Applicable State Law") and therefore may not be offered,
sold, transferred, assigned, pledged, hypothecated or otherwise disposed of,
directly or indirectly, unless subsequently registered or qualified under the
Securities Act and under Applicable State Law or unless any exemptions from the
registration requirements of the Securities Act and Applicable State Law are
available, in each case to the extent permitted by the terms of this Agreement.

               (5)  The Investor understands and agrees that all certificates
representing the Investor Shares shall bear a legend which will be substantially
in the form of the following:

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT
          BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
          (THE "ACT") AND SUCH SECURITIES MAY NOT BE OFFERED, SOLD,
          PLEDGED, TRANSFERRED OR HYPOTHECATED OR OTHERWISE ASSIGNED
          EXCEPT PURSUANT TO (1) A REGISTRATION STATEMENT WITH RESPECT
          TO SUCH SECURITIES WHICH IS EFFECTIVE UNDER SUCH ACT OR (2)
          RULE 144 OR 144A UNDER SUCH ACT OR ANY  OTHER AVAILABLE
          EXEMPTION FROM REGISTRATION UNDER SUCH ACT RELATING TO
          DISPOSITION OF SECURITIES."

               (6)  The Investor (or, if applicable, each managed account on
whose behalf the Investor Shares are being purchased by the Investor) will
acquire the Investor Shares pursuant to this Agreement for its own account for
investment and not with a view to, or in

                                          3
<PAGE>

connection with, the resale or distribution thereof or in any arrangement or
understanding with any other persons regarding the distribution of such Shares
in violation of the Securities Act.

               (7)  The Investor hereby covenants and agrees with the Company
not to make any sale of the Investor Shares without causing the prospectus
delivery requirement under the Securities Act to be satisfied or otherwise
complying with the Securities Act, and the Investor acknowledges and agrees that
the Shares are not transferable on the books of the Company unless the
certificate submitted to the transfer agent evidencing the Investor Shares is
accompanied by (1) a separate certificate (i) in the form of ANNEX V hereto,
(ii) executed by an officer of, or other authorized person designated by, the
Investor, and (iii) to the effect that (A) the Investor Shares have been sold in
accordance with a registration statement pursuant to Section 7 and (B) the
requirement of delivering a current prospectus has been satisfied; or (2) an
opinion of counsel reasonably satisfactory to the Company stating that
registration is not required under the Securities Act.  The Investor
acknowledges that there may be times when the Company may suspend the use of the
prospectus forming a part of a registration statement in the event and during
such period pending negotiations relating to, or consummation of, a transaction
or the occurrence of any other event that would require additional disclosure of
material information by the Company in the registration statement (as to which
the Company has a BONA FIDE business purpose for preserving confidentiality)
that would make it impractical or inadvisable to cause the registration
statement to be filed or to become effective or to amend or supplement the
registration statement or which otherwise renders the Company unable to comply
with the Securities and Exchange Commission (the "Commission") requirements.  In
such event, the Company may suspend the use of such prospectus until such time
as an amendment to such registration statement has been filed by the Company and
declared effective by the Commission, or until such time as the Company has
filed an appropriate report with the Commission pursuant to the Securities
Exchange Act of 1934, as amended (the "Exchange Act"); PROVIDED, HOWEVER, that
such suspension shall not be for a period of more than 30 consecutive trading
days during any one (1) suspension period or more than 60 trading days in any
one (1) year period.  The Investor hereby covenants and agrees that it will not
sell any Investor Shares pursuant to said prospectus during the period
commencing at the time at which the Company gives the Investor written notice of
the suspension of the use of said prospectus and ending the earlier of 30
consecutive trading days after such notice or the date on which the Company
gives the Investor written notice that the Investor may thereafter effect sales
pursuant to said prospectus.

               (8)  The execution and delivery of this Agreement by the Investor
and the performance of this Agreement and the consummation by the Investor or
the Investor's advisory clients, as the case may be, of the transactions
contemplated hereby have been duly authorized by all necessary (corporate, in
the case of a corporation) action of the Investor and, if applicable, the
Investor's advisory clients; and this Agreement, when duly executed and
delivered by the Investor, will constitute a valid and legally binding
instrument, enforceable in accordance with its terms against the Investor or any
of the Investor's advisory clients, as the case may be, except as such
enforceability may be limited by bankruptcy, insolvency, reorganization or
similar laws affecting the enforcement of creditors' rights generally and by
general equitable principles (regardless of whether the issue of enforceability
is considered in a

                                          4
<PAGE>

proceeding in equity or at law) and except as the indemnification and
contribution agreements of the Investor in Section 7(d) hereof may be legally
unenforceable.

               (9)   The Investor represents that:

                    (A)  If the Investor is a corporation, it is a corporation
duly incorporated, validly existing and in good standing under the laws of the

under this Agreement.  Furthermore, the trustee under such trust has
independently determined that the purchase of the Investor Shares is a suitable
investment for such trust as authorized by the terms thereof and applicable laws
and regulations.

                    (D)   If the Investor is a limited partnership, it is a

with full power and authority to act on behalf of its advisory clients under

                    (F)  If the Investor is a corporation, partnership, trust or
other form of business entity, the execution and delivery of this Agreement will
not contravene or result in a default under any provision of existing law or
regulations to which the Investor is subject, the provisions of its trust
instrument, charter, by-laws or other governing documents or any indenture,
mortgage or other agreement or instrument to which it is a party or by which it
is bound and does not require on its part any approval, authorization, license
or filing from or with any foreign, federal, state or municipal board or agency
which has not been obtained or duly made.

                    (G)  If the Investor is an individual, the Investor has full
power and authority to perform its obligations under this Agreement.

<PAGE>

affecting the enforcement of creditors' rights generally and by general
equitable principles (regardless of whether the issue of enforceability is

consummation by the Company of the transactions herein contemplated and the
compliance by the Company with the terms hereof do not and will not violate the
Articles of Incorporation of the Company, or the By-Laws of the Company, or

available funds to Goodwin, Procter & Hoar  LLP, as the designated escrow agent
(the "Escrow Agent"), US $________________ (the "Escrow Amount") to be held by
the Escrow Agent; PROVIDED, HOWEVER, that the Placement Agent may retain during
the period that the Escrow Amount is held in escrow an amount of cash equal to
its placement commission in an amount equal to 6.0% of the Escrow Amount,
subject to the sentence immediately prior to the last sentence of this
paragraph.  The Company shall reimburse the Placement Agent for up to $3,500 of

contained in any of the statements made herein by the Investor) shall be without
liability of the Company or the Investor.

     7.   REGISTRATION OF THE SHARES; COMPLIANCE WITH THE SECURITIES ACT.

          (a)  REGISTRATION RIGHTS; REGISTRATION PROCEDURES AND EXPENSES.

               (1)  If at any time or times after the date hereof, the Company
shall determine or be required to register any shares of its Common Stock for
sale under the Securities Act (whether in connection with a public offering of
securities by the Company (a "primary offering"), a public offering of
securities by stockholders of the Company (a

                                          9
<PAGE>

"secondary offering") or both), but not in connection with a registration
effected solely to implement an employee benefit plan or a transaction to which
Rule 145 or any other similar rule of the Commission under the Securities Act is
applicable, the Company shall:

                    (i)   Promptly give written notice thereof to each of the
Investors.

                    (ii)  Use reasonable efforts to effect the registration
under the Securities Act of all Investor Shares (but not any other shares) which
such Investors request to be registered in a writing delivered to the Company
within 20 days after such Investors' receipt of the notice referred to above,
subject to subparagraph (iii) below.

                    (iii) In the case of the registration of shares of Common
Stock by the Company in connection with an underwritten public offering, (i) the
Company shall not be required to include any Investor Shares in such
underwriting unless the Investors thereof accept the terms of the underwriting
as agreed upon between the Company and the underwriter or underwriters selected
by it, and (ii) if the underwriter(s) determines that marketing factors require
a limitation on the number of Investor Shares to be offered, the Company shall
not be required to register Investor Shares of the Investors in excess of the
amount, if any, of shares of the capital stock which the principal underwriter
of such underwritten offering shall reasonably and in good faith agree to
include in such offering in excess of any amount to be registered for the
Company, and in the event of any such limitation the number of Investor Shares
of any Investor requesting inclusion in such registration shall be based upon
the relative holdings of Common Stock of all Investors requesting such
registration (and if any Investor would thus be entitled to include more
Investor Shares than such Investor requested to be registered, the excess shall
be allocated among other requesting Investors PRO RATA based upon their relative
holdings of Common Stock).  All expenses relating to the registration and
offering of Investor Shares pursuant to this Section 7(a)(1) shall be borne by
the Company, except that the Investors shall bear underwriting and selling
commissions attributable to their Investor Shares being registered and any
transfer taxes on shares being sold by such Investors.

               (2)  The Company shall:

                    (a)   Prepare and file with the Commission within sixty (60)
days of the Closing a registration statement (the "Registration Statement") to
enable the sale of the Investor Shares by the Investor from time to time through
the automated quotation system of the Nasdaq SmallCap Market or in
privately-negotiated transactions or otherwise.

                    (b)   Use reasonable efforts, subject to receipt of
necessary information from the Investor, to cause the Registration Statement to
become effective as soon as possible after filing thereof.

                    (c)   Promptly prepare and file with the Commission such
amendments and supplements to the Registration Statement and the prospectus used
in connection therewith as may be necessary to keep the Registration Statement
effective for a

                                          10
<PAGE>

period not exceeding the third anniversary of the Closing, or such shorter
period which will terminate on the earlier of the date when (i) the Shares held
by the Investor may be sold without registration under the Securities Act or
(ii) all of the Shares covered by such Registration Statement have been sold
pursuant to such Registration Statement or otherwise.

                    (d)   Promptly furnish to the Investor with respect to the
Investor Shares registered under the Registration Statement (and to each
underwriter, if any, of such Investor Shares) such number of copies of the
Registration Statement and any amendment or supplement thereto and of
prospectuses and preliminary prospectuses in conformity with the requirements of
the Securities Act and such other documents as the Investor may reasonably
request, in order to keep the Investor apprised of the progress of the
registration process and to facilitate the public sale or other disposition of
all or any of the Investor Shares by the Investor.

                    (e)   Promptly file documents required of the Company for
customary "blue sky" clearance in states specified in writing by the Investor
and reasonably required by the Investor in order to resell its Investor Shares;
PROVIDED, HOWEVER, that the Company shall not be required to qualify to do
business or consent to service of process in any jurisdiction in which it is not
now so qualified or has not so consented.

                    (f)   Promptly inform the Investor when any stop order by
the Commission has been issued with respect to the Investor Shares and use its
best efforts to promptly cause such stop order to be withdrawn.

                    (g)   Bear all expenses in connection with the procedures in
subparagraphs (a) through (i) of this Section 7(a)(2) and the registration of
the Investor Shares pursuant to the Registration Statement, other than fees and
expenses, if any, of counsel or other advisors to the Investor, PROVIDED that
the Company shall pay the reasonable fees and expenses of one counsel to the
Investors purchasing Shares in the Private Placement.

                    (h)   Take such other actions as may reasonably be necessary
to effect the registration of the resale of the Investor Shares in accordance
with the terms of this Agreement and to allow such Investor Shares to trade in
the same market system or exchange where the Company's Common Stock then trades.

                    (i)   File the reports required to be filed by it under the
Securities Act and the Exchange Act (or, if the Company is not required to file
such reports, it will, upon the request of any holder of Investor Shares, make
publicly available other information so long as necessary to permit sales under
Rule 144 under the 1933 Act), all to the extent required from time to time to
enable the Investor to sell Investor Shares without registration under the
Securities Act within the limitations provided by (i) Rule 144 under the
Securities Act, as such Rule may be amended from time to time, or (b) any
similar rule or regulation hereafter adopted by the Commission; PROVIDED,
HOWEVER, that nothing in this Agreement shall require the Company to file
reports under the Securities Act or the Exchange Act, to register any of its
securities under the Exchange Act, or to make publicly available any

                                          11
<PAGE>

information concerning the Company at any time when it is not required by law or
by any agreement by which it is bound to do any of the foregoing.

A questionnaire related to the Registration Statement to be completed by the
Investor is attached hereto as ANNEX IV.

          (b)  INTENTIONALLY OMITTED.

          (c)  TRANSFER OF SHARES.  The Investor agrees not to effect any
disposition of the Shares or the right to purchase the Shares that would
constitute a sale within the meaning of the Securities Act except as
contemplated in Sections 7(a)(1)and(2) or pursuant to an exemption from
registration under the Securities Act.  The Investor agrees to promptly notify
the Company of any changes in the information set forth in any registration
statement regarding the Investor Shares or the Investor.

          (d)  INDEMNIFICATION AND CONTRIBUTION.  For the purpose of this
Section 7(d):

               (1)  The term "Selling Shareholder" shall include the Investor,
officers, directors, trustees, or any affiliate of such Investor and each
person, if any, who controls the Selling Shareholder within the meaning of the
Securities Act;

               (2)  The term "Registration Statement" shall include (i) the
Registration Statement and any final prospectus, exhibit, supplement or
amendment included in or relating to the Registration Statement and (ii) any
registration statement filed in connection with Section 7(a)(i) and any final
prospectus, exhibit, supplement or amendment included in or relating to such
registration statement; and

               (3)  The term "untrue statement" shall include any untrue
statement or alleged untrue statement, or any omission or alleged omission to
state in the Registration Statement a material fact required to be stated
therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

     The Company agrees to indemnify and hold harmless each Selling Shareholder
from and against any losses, claims, damages or liabilities to which such
Selling Shareholder may become subject (under the Securities Act or otherwise)
insofar as such losses, claims, damages  or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading or arise out of any failure by the Company to fulfill any
undertaking included in the Registration Statement and the Company will
reimburse such Selling Shareholder for any reasonable legal or other expenses
reasonably incurred in investigating, defending or preparing to defend any such
action, proceeding or claim, PROVIDED, HOWEVER, that the Company shall not be
liable in any such case to the extent that such loss, claim, damage or liability
arises out of, or is based upon, any such untrue statement or omission made in
such Registration Statement in reliance upon

                                          12
<PAGE>

and in conformity with written information furnished to the Company by or on
behalf of such Selling Shareholder specifically for use in preparation of the
Registration Statement, or the failure of such Selling Shareholder to comply
with the covenants and agreements contained in Sections 3(a) and 7(c) hereof
respecting sale of the Shares or any statement or omission in any prospectus
that is corrected or made not misleading in any subsequent prospectus that was
delivered to the Investor prior to the pertinent sale or sales by the Investor.

     The Investor agrees to indemnify and hold harmless the Company (and each
person, if any, who controls the Company within the meaning of Section 15 of the
Securities Act, each officer of the Company who signs the Registration Statement
and each director of the Company) from and against any losses, claims, damages
or liabilities to which the Company (or any such officer, director or
controlling person) may become subject (under the Securities Act or otherwise),
insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon, any failure to
comply with the covenants and agreements contained in Sections 3(a) and 7(c)
hereof respecting sale of the Shares, or any untrue statement of a material fact
contained in the Registration Statement on the effective date thereof if such
untrue statement was made in reliance upon and in conformity with written
information furnished by or on behalf of the Investor specifically for use in
preparation of the Registration Statement, PROVIDED, HOWEVER, that such Investor
shall not be liable in any such case to the extent that the Investor has
furnished in writing to the Company information expressly for use in such
Registration Statement or any amendment thereof or supplement thereto which
corrected or made not misleading information previously furnished to the Company
prior to the filing of the Registration Statement, and if thereafter, has
notified the Company of such information immediately upon its occurrence or the
Investor's knowledge of its occurrence.  The Investor will reimburse the Company
(or such officer, director or controlling person), as the case may be, for any
legal or other expenses reasonably incurred in investigating, defending or
preparing to defend any such action, proceeding or claim.  In no event shall the
liability of the Investor hereunder be greater in amount than the dollar amount
of the proceeds received by such Investor upon the sale of the Shares giving
rise to such indemnification obligation.

     Promptly after receipt by any indemnified person of a notice of a claim or
the beginning of any action in respect of which indemnity is to be sought
against an indemnifying person pursuant to this Section 7(d), such indemnified
person shall notify the indemnifying person in writing of such claim or of the
commencement of such action, and, subject to the provisions hereinafter stated,
in case any such action shall be brought against an indemnified person and such
indemnifying person shall be entitled to participate therein, and, to the extent
it shall wish, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified person.  After notice from the indemnifying
person to such indemnified person of its election to assume the defense thereof,
such indemnifying person shall not be liable to such indemnified person for any
legal expenses subsequently incurred by such indemnified person in connection
with the defense thereof, PROVIDED, HOWEVER, that if there exists or shall exist
a conflict of interest that would make it inappropriate, in the opinion of
counsel to the indemnified person, for the same counsel to represent both the
indemnified person and such indemnifying person or any affiliate or associate
thereof, the indemnified person shall be entitled to retain its own

                                          13
<PAGE>

counsel at the expense of such indemnifying person; PROVIDED, HOWEVER, that no
indemnifying person shall be responsible for the fees and expenses of more than
one separate counsel for all indemnified parties.

     If the indemnification provided for in this Section 7(d) from the
indemnifying person is unavailable to an indemnified person hereunder in respect
of any losses, claims, damages, liabilities or expenses referred to herein, then
the indemnifying person, in lieu of indemnifying such indemnified person, shall
contribute to the amount paid or payable by such indemnified person as a result
of such losses, claims, damages, liabilities or expenses in such proportion as
is appropriate to reflect the relative fault of the indemnifying person and
indemnified persons in connection with the actions which resulted in such
losses, claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations.  The relative fault of such indemnifying person and
indemnified persons shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact, has been made by, or relates to information supplied by,
such indemnifying person or indemnified persons, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such action.  The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and expenses referred to above shall be deemed to
include, subject to the limitations set forth in this Section 7(d), any
reasonable legal or other fees or expenses reasonably incurred by such party in
connection with any investigation or proceeding.

     The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 7(d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 7(d), no Investor shall be
required to contribute any amount in excess of the dollar amount of the proceeds
received by such Investor upon the sale of the Shares giving rise to such
contribution obligation.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

          (e)  TERMINATION OF CONDITIONS AND OBLIGATIONS.  The conditions
precedent imposed by Section 4 or this Section 7 upon the transferability of the
Investor Shares shall cease and terminate as to any particular number of the
Investor Shares when such Investor Shares shall have been effectively registered
under the Securities Act and sold or otherwise disposed of in accordance with
the intended method of disposition set forth in the registration statement
covering such Investor Shares or at such time as an opinion of counsel
satisfactory to the Company shall have been rendered to the effect that such
conditions are not reasonably necessary in order to comply with the Securities
Act.

          (f)  INFORMATION AVAILABLE.  So long as a registration statement is
effective covering the resale of the Investor Shares, the Company will furnish
to the Investor:

                                          14
<PAGE>

               (1)  As soon as practicable after available (but in the case of
the Company's Annual Report to Shareholders, within one hundred twenty (120)
days after the end of each fiscal year of the Company), one copy of (i) its
Annual Report to Shareholders (which Annual Report shall contain financial
statements audited in accordance with generally accepted accounting principles
by a national firm of certified public accountants), (ii) if not included in
substance in the Annual Report to Shareholders, its Annual Report on Form 10-KSB
or equivalent form, (iii) its Quarterly Reports to Shareholders, (iv) if not
included in substance in its Quarterly Reports to Shareholders, its quarterly
reports on Form 10-QSB or equivalent form, and (v) a full copy of the particular
registration statement covering the Shares (the foregoing, in each case,
excluding exhibits);

               (2)  Upon the reasonable request of the Investor, all exhibits
excluded by the parenthetical to subparagraph (i) of this Section 7(f) and all
other information that is made available to shareholders; and

               (3)  Upon the reasonable request of the Investor, an adequate
number of copies of the prospectuses to supply to any other party requiring such
prospectuses;

and the Company, upon the reasonable request of the Investor, will meet with the
Investor or a representative thereof at the Company's headquarters to discuss
all information relevant for disclosure in the registration statement covering
the Investor Shares and will otherwise cooperate with any Investor conducting an
investigation for the purpose of reducing or eliminating such Investor's
exposure to liability under the Securities Act, including the reasonable
production of information at the Company's headquarters.

     8.   MISCELLANEOUS.

                                THE TORO COMPANY
                              DIRECTORS STOCK PLAN

1.  PURPOSE OF THE PLAN. The purpose of The Toro Company Directors Stock Plan
    ("Plan") is to enable The Toro Company (the "Company") to attract and retain
    experienced and knowledgeable directors to serve on the Board of Directors
    of the Company or its subsidiaries, and to further align their interests
    with those of the stockholders of the Company by providing for or increasing
    their stock ownership interests in the Company. It is intended that the Plan
    be interpreted so that transactions under the Plan are exempt under Rule
    16b-3 under the Securities Exchange Act of 1934, as amended (the "Exchange
    Act"), to the extent applicable.

2.  ELIGIBILITY. All members of the Company's Board of Directors who are not
    current employees of the Company or any of its subsidiaries ("Nonemployee
    Directors") are eligible to participate in the Plan.

3.  PLAN AWARDS.

    a.  DIRECTORS SHARES. To carry out the purposes of the Plan, the Company
        shall issue shares ("Directors Shares") of the Company's Common Stock,
        $1.00 par value and related preferred share purchase rights (subject to
        adjustment as provided in Section 4 hereof) (the "Common Stock"), to
        each person who is then a Nonemployee Director, on the first day of each
        fiscal year in an amount equal to $10,000 divided by the fair market
        value of one share of Common Stock. The fair market value of one share
        of Common Stock shall be the average of the 4 p.m. Eastern Time closing
        prices of the Common Stock as reported by the New York Stock Exchange
        for each of the trading days in the three calendar months immediately
        prior to the date of issue of the Directors Shares.

    b.  DIRECTORS OPTIONS.

        i.  ANNUAL GRANT. Subject to the terms and conditions of this Section
            3.b., the Company shall grant a nonqualified option ("Directors
            Options") to purchase 1,000 shares of the Common Stock, to each
            person who is then a Nonemployee Director, on the first day of each
            fiscal year at an exercise price per share equal to the fair market
            value of one share of Common Stock on the date of grant. The fair
            market value of one share of Common Stock shall be the 4 p.m.
            Eastern Time closing price of the Common Stock as reported by the
            New York Stock Exchange for the first business day of the Company's
            fiscal year with respect to which the grant is made.

        ii. OPTION TERMS.

            (a) Directors Options shall be exercisable in whole or in part
                commencing six months following the date of grant and shall
                remain exercisable for a term of five years after the date of
                grant.

            (b) No Directors Option shall be assigned or transferred, except by
                will or the laws of descent and distribution. An option so
                transferred may be exercised after the death of the individual
                to whom it is granted only by such individual's legal
                representatives, heirs or legatees, not later than the earlier
                of the date the option expires or one year after the date of
                death of such individual, and only with respect to an option
                exercisable at the time of death.

            (c) During the lifetime of a Nonemployee Director, options held by
                such individual may be exercised only by the Nonemployee
                Director and only while serving as a member of the Board of
                Directors of the Company and only if the Nonemployee Director
                has been continuously so serving since the date such options
                were granted; provided, however, that in the event of disability
                of a Nonemployee Director, options may be exercised by such
                individual not later than the earlier of the date the option
                expires or one year after the date such service as a member of
                the Board of Directors ceases by reason of disability, but only
                with respect to an option exercisable at the time such service
                ceases.
<PAGE>

            (d) Payment of the exercise price may be made in cash, in shares of
                Common Stock valued at fair market value on the date of exercise
                or in a combination of cash and Common Stock.

    c.  SHARE PRORATION. If, on any date on which Directors Shares are to be
        issued pursuant to Section 3.a. or Directors Options are to be granted
        pursuant to Section 3.b., the number of shares of Common Stock is
        insufficient for the issuance of the entire number of shares to be
        issued or the grant of the entire number of options as calculated in
        accordance with Section 3.a. or Section 3.b., then the number of shares
        to be issued to each Nonemployee Director entitled to receive Directors
        Shares or Directors Options on such date shall be such Nonemployee
        Director's proportionate share of such available number of shares or
        options (rounded down to the greatest number of whole shares), provided
        that if a sufficient number of shares of Common Stock is available to
        issue all of the Directors Shares, then the entire number of Directors
        Shares shall be issued first and the number of shares to be subjected to
        options shall be prorated in accordance with this section.

    d.  SUPPLEMENTAL BENEFIT. Directors Shares and Directors Options are a
        supplemental benefit and are not a component of the annual retainer and
        meeting fees paid to Nonemployee Directors. The value of Directors
        Shares and Directors Options shall not be included in the calculation by
        the Company of the amount of compensation upon which a Nonemployee
        Director's retirement benefit is calculated for purposes of the
        Company's Director Retirement Plan or any similar plan.

4.  SHARES IN LIEU OF FEES. A Nonemployee Director shall have the right to elect
    to receive shares of Common Stock in lieu of annual retainer and meeting
    fees otherwise payable in cash. The election to receive Common Stock shall
    be made prior to the first day of the calendar year in which the fees are to
    be earned. Fees that are earned shall be reserved through the year and
    shares shall be issued in December of that year. The number of shares to be
    issued shall be determined by dividing the amount of the cash that otherwise
    would have been paid by the market value of one share of Common Stock on the
    date that the shares are issued.

5.  STOCK SUBJECT TO PLAN. Subject to adjustment as provided in this paragraph
    and subject to increase by amendment of the Plan, the total number of shares
    of Common Stock that is reserved and available for issuance in connection
    with the Plan shall be 65,000 shares. If any Directors Option granted
    hereunder expires unexercised or terminates, the shares of Common Stock
    reserved for issuance pursuant to such option shall, to the extent of any
    such termination or to the extent the shares covered by an option are not
    issued or used, again be available for option grants under the Plan. Any
    shares issued by the Company in connection with the assumption or
    substitution of outstanding option grants from any acquired corporation
    shall not reduce the shares available for stock awards or option grants
    under the Plan. In the event of a corporate transaction involving the
    Company, the Common Stock or the Company's corporate or capital structure,
    including but not limited to any stock dividend, stock split, extraordinary
    cash dividend, recapitalization, reorganization, merger, consolidation,
    reclassification, split-up, spin-off, combination or exchange of shares, or
    a sale of the Company or of all or part of its assets or any distribution to
    stockholders other than a normal cash dividend, the Committee shall make
    such proportional adjustments as are necessary to preserve the benefits or
    potential benefits of the Directors Shares and Directors Options. Action by
    the Committee may include all or any of adjustment in (a) the maximum number
    and kind of securities subject to the Plan as set forth in this paragraph;
    (b) the maximum number and kind of securities that may be made subject to
    Directors Options and the determination of the number or kind of Directors
    Shares; (c) the number and kind of securities subject to any outstanding
    Directors Option; and (d) any other adjustments that the Committee
    determines to be equitable.

6.  CHANGE OF CONTROL. In the event of a Change of Control of the Company as
    hereinafter defined, all options shall fully vest, unless otherwise limited
    by the Committee at the time of the option grant, and

                                       2
<PAGE>

    be exercisable in their entirety immediately, and notwithstanding any other
    provisions of the Plan, shall continue to be exercisable for three years
    following the Change of Control, but not later than ten years after the date
    of grant.

    Change of Control means:

    a.  The acquisition by any individual, entity or group (within the meaning
        of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a "Person") of
        beneficial ownership (within the meaning of Rule 13d-3 under the
        Exchange Act) of 15% or more of either (i) the then-outstanding shares
        of Common Stock of the Company (the "Outstanding Company Common Stock")
        or (ii) the combined voting power of the then-outstanding voting
        securities of the Company entitled to vote generally in the election of
        directors (the "Outstanding Company Voting Securities"); provided,
        however, that for purposes of this subsection a., the following
        acquisitions shall not constitute a Change of Control: (i) any
        acquisition directly from the Company, (ii) any acquisition by the
        Company, (iii) any acquisition by any employee benefit plan (or related
        trust) sponsored or maintained by the Company or any corporation
        controlled by the Company, or (iv) any acquisition by any corporation
        pursuant to a transaction that complies with clauses (i), (ii) and (iii)
        of subsection c. of this Section 6; or

    b.  Individuals who, as of the date hereof, constitute the Board of
        Directors of the Company (the "Incumbent Board") cease for any reason to
        constitute at least a majority of the Board; provided, however, that any
        individual becoming a director subsequent to the date hereof whose
        election, or nomination for election by the Company's stockholders, was
        approved by a vote of at least a majority of the directors then
        comprising the Incumbent Board shall be considered as though such
        individual were a member of the Incumbent Board, but excluding, for this
        purpose, any such individual whose initial assumption of office occurs
        as a result of an actual or threatened election contest with respect to
        the election or removal of directors or other actual or threatened
        solicitation of proxies or consents by or on behalf of a Person other
        than the Board; or

    c.  Consummation of a reorganization, merger or consolidation of the Company
        or sale or other disposition of all or substantially all of the assets
        of the Company or the acquisition by the Company of assets or stock of
        another entity (a "Business Combination"), in each case, unless,
        following such Business Combination, (i) all or substantially all of the
        individuals and entities who were the beneficial owners, respectively,
        of the Outstanding Company Common Stock and Outstanding Company Voting
        Securities immediately prior to such Business Combination beneficially
        own, directly or indirectly, more than 50% of, respectively, the
        then-outstanding shares of common stock and the combined voting power of
        the then-outstanding voting securities entitled to vote generally in the
        election of directors, as the case may be, of the corporation resulting
        from such Business Combination (including, without limitation, a
        corporation which as a result of such transaction owns the Company or
        all or substantially all of the Company's assets either directly or
        through one or more subsidiaries) in substantially the same proportions
        as their ownership, immediately prior to such Business Combination of
        the Outstanding Company Common Stock and Outstanding Company Voting
        Securities, as the case may be, (ii) no Person (excluding any
        corporation resulting from such Business Combination or any employee
        benefit plan (or related trust) of the Company or such corporation
        resulting from such Business Combination) beneficially owns, directly or
        indirectly, 15% or more of, respectively, the then-outstanding shares of
        common stock of the corporation resulting from such Business
        Combination, or the combined voting power of the then-outstanding voting
        securities of such corporation except to the extent that such ownership
        existed prior to the Business Combination and (iii) at least a majority
        of the members of the board of directors of the corporation resulting
        from such Business Combination were members of the Incumbent Board at
        the time of the execution of the initial agreement, or of the action of
        the Board, providing for such Business Combination; or

                                       3
<PAGE>

    d.  Approval by the stockholders of the Company of a complete liquidation or
        dissolution of the Company.

7.  ADMINISTRATION OF THE PLAN. The Plan shall be administered by a committee
    composed of those members of the Board of Directors of the Company who are
    also employees of the Company (the "Committee"). The Committee shall have
    the authority to carry out all provisions of the Plan; provided, however,
    that it shall have no discretion to determine which Nonemployee Directors
    may receive Directors Shares or Directors Options or to set the value of
    such Directors Shares or Directors Options, other than to make the
    calculations required by Section 3.a. and Section 3.b.

8.  TERM OF PLAN. The Plan became effective on August 20, 1992 and shall be
    perpetual, unless sooner terminated by action of the Board of Directors.

9.  AMENDMENT. The effective date of any amendment to the Plan shall be the date
    of its adoption by the Board of Directors. No amendment of the Plan shall
    adversely affect in a material manner any right of any option holder with
    respect to any option theretofore granted without such option holder's
    written consent.

10. GOVERNING LAW. The Plan, options and awards granted under the Plan and
    agreements entered into under the Plan shall be construed, administered and
    governed in all respects under and by the applicable laws of the State of
    Delaware, excluding any conflicts or choice of law rule or principle that
    might otherwise refer construction or interpretation of the Plan or an
    option or an award or agreement to the substantive law of another
    jurisdiction.
