     1. PURPOSE.  The Modine Manufacturing Company 2000 Stock

Option Plan for Non-Employee Directors (the "Directors' Plan") is

intended to promote the interests of Modine Manufacturing Company

(the "Company") and its stockholders by providing potential

compensation for the non-employee members of the Company's Board

of Directors, thereby assisting the Company in its efforts to

attract and retain well qualified individuals to serve as its

directors.  Options granted under the Directors' Plan are

intended to be of a type that does not meet all of the

requirements of Section 422A of the Internal Revenue Code of 1986

as heretofore and hereafter amended, and the Directors' Plan

shall be construed so as to carry out that intention.



     2. ADMINISTRATION.



        (a) Procedure; Disinterested Directors.  The Board will
            ----------------------------------

appoint a committee (the "Committee") of two (2) or more

directors to administer the Plan if deemed necessary or advisable

in order to comply with the exemptive rules promulgated pursuant

to Section 16(b) of the Securities Exchange Act of 1934, as

amended (the "Exchange Act").



        (b) Powers.  Grants of Options under the Plan and the
            ------

amount, price, and timing of the awards to be granted will be

automatic as described in Section 5.  However, all questions of

interpretation of the Plan will be determined by the Board or the

Committee, as applicable, and such determination will be final

and binding upon all parties.



        (c) Section 16 Compliance.  Transactions under this
            ---------------------

Directors' Plan are intended to comply with all applicable

conditions of Rule 16b-3 or its successors under the Exchange

Act.  To the extent any provision of the Directors' Plan or

action by the Board or Committee fails to so comply, it shall be

deemed null and void, to the extent permitted by law and deemed

advisable by the Board or Committee.  In addition, to the extent

a participant (who is also a Reporting Person under Rule 16b-3 or

its successors) engages in an opposite way transaction that

jeopardizes the exemption, it shall be deemed null and void.

or future directors of the Company who are not employees of the

Company.

shares equal to the multiple of six thousand (6,000) and the

number of years in the term to which he has been elected to the

Company's Board of Directors.

stock splits, or similar transactions), the total number of

shares reserved for issuance under this Directors' Plan and the

number of shares covered by each outstanding Director's Stock

Option shall be adjusted so that the aggregate consideration

payable to the Company, if any, and the value of each such option

shall not be changed.

termination of any Director's Stock Options held by him

hereunder, each Director's Stock Option theretofore granted to

him shall be exercisable to the extent provided therein but not

later than one year after his death (and not beyond the stated

duration of the Director's Stock Option).  Any such exercise

shall be made only:



        (a) By the executor or administrator of the estate of the

deceased participant  or the person or persons to whom the

deceased participant's rights under the Director's Stock Option

shall pass by will or the laws of descent and distribution; and



        (b) To the extent, if any, that the deceased participant

was entitled at the date of his death.



    11. OTHER PROVISIONS.  The award of any Director's Stock

Option under the Directors' Plan may also be subject to such

for the installment purchase of Common Stock under Directors'

Stock Options, provisions to assist the participant in financing

the acquisition of Common Stock, provisions for the forfeiture

of, or restriction on resale or other disposition of shares

acquired under Directors' Stock Options, provisions giving the

Company the right to repurchase shares acquired under Directors'

Stock Options in the event the participant elects to dispose of

such shares, provisions to comply with federal and state tax or

securities laws, or understandings or conditions as to the length

of the participant's term as a director in addition to those

specifically provided for under the Directors' Plan.



    12. TENURE.  A participant's right, if any, to continue to

serve the Company as a director shall not be enlarged or

        (a) Term.  No Director's Stock Option shall be granted
            ----

more than ten years after the date of adoption of this Directors'

Plan;  provided, however,  that  the  terms  and  conditions

applicable to Directors' Stock Options granted within such period

may thereafter be amended or modified by mutual agreement between

the Company and the participant or such other person as may then

have an interest therein.  Also, by mutual agreement between the


Company and a participant hereunder, or under any future plan of

the Company, Directors' Stock Options may be granted to such

participant in substitution and exchange for and in cancellation

of, any Directors' Stock Options previously granted such

participant under this Directors' Plan.



        (b) Termination.  The Plan may be terminated at any time
            -----------

by the Board or by the approval by the holders of a majority of

the shares of the Common Stock present, or represented, and

entitled to vote at a meeting held for such purpose.



        (c) Amendment.  The Plan may be amended by the Board or
            ---------

Committee; provided however, that (i) no amendment shall be made

that would impair prior grants or rights of a participant without

his consent; (ii) no amendment shall be made more frequently than

once every six months, unless such amendment is required because

of changes in the Internal Revenue Code or the Employee

Retirement Income Security Act; (iii) no amendment shall be made

which would prevent a participant's participation in the Plan

from being entitled to an exemption from Section 16(b) of the

Act.



    14. EFFECTIVE DATE.  The Directors' Plan has been adopted by

the Board of Directors on May 17, 2000, and shall be effective
