                  MODINE MANUFACTURING COMPANY
                        STOCK OPTION PLAN
                    FOR THERMACORE EMPLOYEES
                            UNDER THE
             DTX CORPORATION 1995 STOCK OPTION PLAN


     The "Modine Manufacturing Company Stock Option Plan for
Thermacore Employees Under the DTX Corporation 1995 Stock Option
Plan" has been adopted by Modine Manufacturing Company ("Modine")
pursuant to the terms and conditions of an Agreement and Plan of
Merger, dated December 13, 2000, as amended by the First
Amendment thereto, dated March 15, 2001, among Modine, Modine
Merger Co., and Thermacore International, Inc., formerly known as
DTX Corporation ("Thermacore"), providing for the merger of
Modine Merger Co., a wholly owned subsidiary of Modine, with and
into Thermacore (the "Merger"), effective as of April 27, 2001,
the effective date of  the Merger.  Effective as of that same
date, Modine changed the name of the plan to its present name and
amended and restated the plan in its entirety to read as follows:

1.   PURPOSE OF THE PLAN.
     -------------------

     This Modine Manufacturing Company Stock Option Plan for
     Thermacore Employees under the DTX Corporation 1995 Stock
     Option Plan (hereinafter referred to as the "Plan") is
     intended to advance the interests of Thermacore and Modine by
     providing key employees who have substantial responsibility
     for the direction and management of Thermacore or any
     subsidiary corporation with additional incentive for them
     to promote the success of Thermacore, as a wholly owned
     subsidiary of Modine, and by increasing their proprietary
     interest in Modine under conditions which will encourage
     their continued employment in the service of Thermacore.

2.   ADMINISTRATION OF THE PLAN.
     --------------------------

     (a)  The Plan shall be administered by the Compensation
          Committee (hereinafter referred to as the "Committee")
          of the Board of Directors of Thermacore (hereinafter
          referred to as the "Board"); provided, however, that
          effective as of the effective date of the Merger, all
          responsibility for the administration of the Plan shall
          be assumed by the Officer Nomination and Compensation
          Committee of the Board of Directors of Modine, all
          references in this Plan to the "Committee" shall
          henceforth be deemed to be references to that
          committee, and all references to the "Board" shall
          henceforth be deemed to be references to the Board of
          Directors of Modine.

     (b)  The Committee shall act by a majority vote; provided,
          however, that no option may be granted without the
          affirmative vote of at least one director who is not a
          participant in the Plan.

     (c)  Without limiting the scope of such authority, but
          always being subject to the other provisions of the
          Plan, the Committee shall have the plenary authority,
          in its sole discretion to recommend to the Board:  (i)
          the employees of Thermacore or any subsidiary
          corporation of Thermacore to whom options shall be
          granted; (ii) the time or times at which options shall
          be granted; (iii) the option price of the shares
          subject to each option; (iv) the time or times when
          each option shall become exercisable and the duration
          of the exercise period; (v) the number of shares of the
          stock to be granted pursuant to the Plan; and (vi)
          interpretations of the Plan and actions to prescribe,
          amend, and rescind rules and regulations for putting it
          into effect and administering it.  The Committee shall
          place its recommendations before the Board in the form
          of a motion.

     (d)  The Committee may consult with counsel, who may be
          counsel to the Company, and shall not incur any
          liability for any action taken in good faith and
          reliance upon the advice of counsel.

     (e)  The form of the options granted pursuant to this Plan
          shall be evidenced by Stock Option Agreements in such
          form as the committee shall from time to time adopt.
          Options may, but need not, be subject to such terms and
          conditions as will qualify their holders for special
          Federal income tax treatment pursuant to any provision
          of the Internal Revenue Code of 1986 as may be enacted
          from time to time.  Each option granted under this Plan
          shall be exercisable on such date or dates and during
          such period and for such number of shares as shall be
          determined pursuant to the provisions of the Stock
          Option Agreement with respect to such option; provided,
          however, that no option shall be exercised later than
          ten years from the date of grant of the option.

3.   SHARES OF THE STOCK SUBJECT TO THE PLAN.
     ---------------------------------------

     An aggregate of 15,000 shares of Thermacore common stock was
     originally reserved for use upon the exercise of options to
     be granted from time to time under the Plan, as such number
     may have been adjusted, from time to time, under Section 8
     of the Plan.  Upon the effective date of the Merger, each
     outstanding option to acquire one share of Thermacore common
     stock under the Plan was converted into an option to acquire
     1.01592 shares of Modine common stock.  Effective as of the
     effective date of the Merger, 25,778 shares of Modine common
     stock will be reserved for use upon the exercise of options
     previously granted under the Plan. Following the effective
     date of the Merger, no additional options will be granted
     under the Plan. The shares to be issued upon exercise of
     options granted under this Plan shall be made available at
     the discretion of the Board either from authorized by
     unissued shares of common stock or from issued shares of
     common stock reacquired by Modine.


4.   ELIGIBILITY AND PARTICIPATION.
     -----------------------------

     (a)  Options may be granted only to persons who are key
          employees of Thermacore or a subsidiary corporation of
          Thermacore.  The term "key employees" shall include
          officers, directors, executives, and supervisory
          personnel, as well as other employees of Thermacore or
          any subsidiary corporation of Thermacore who perform
          services of major importance in the management,
          operation, and development of Thermacore or any
          subsidiary corporation of Thermacore; provided,
          however, that the term "key employees" shall not
          include a director who is not also a full-time employee
          of Thermacore or a subsidiary corporation of
          Thermacore.  For the purpose of this Plan, "employee"
          shall mean any individual who qualifies as a "key
          employee."

     (b)  Notwithstanding any other provision of this Plan, the
          aggregate fair value (determined at the time the
          options are granted) of the stock for which any
          employee may be granted stock options in any calendar
          year, under this or any such stock option plan
          established by Thermacore or any subsidiary corporation
          of Thermacore shall not exceed $100,000.00, plus any
          unused limit carryover to such calendar year, as defined
          in Section 422A(c)(4) of the Internal Revenue Code.

5.   OPTION PRICE.
     ------------

     (a)  The purchase price per share of stock covered by a
          qualified option shall be determined by the Board at
          the time the option is granted, but in no event shall
          the option price be less than the fair value of the
          common stock shares at the time the option is granted
          as required by Section 422A(b)(4) of the Internal
          Revenue Code; provided, however, that with respect to
          any incentive stock options granted to an employee who,
          at the time of the option is granted, owns stock
          possessing more than 10 percent (10%) of the total
          combined voting power of all classes of stock of
          Thermacore or any subsidiary corporation of Thermacore
          ("Ten Percent Stockholder"), the option price per share
          shall have been at least 110 percent (110%) of such
          fair value of the stock subject to the option at the
          time the option is granted.  The fair value shall mean,
          on any given date, the mean between the highest and
          lowest prices of actual sales of shares of the common
          stock on the principal national securities exchange on
          which the  common stock is listed on such date or, if
          the common stock is not so listed on such date, then
          fair value shall be the set price as determined
          periodically by the Board in good faith or in the
          manner established by the Board from time to time.

     (b)  In determining the fair value of the shares on the date
          of the grant of the option, if such shares of common

          stock are not listed on a national securities exchange,
          the Board will consider a variety of factors, including
          past and current earnings, earnings estimates, the
          ratio of Thermacore capital stock to debt, book value,
          other factors affecting the business and long range
          prospects of Thermacore and general economic
          conditions; provided, however, that all valuations of
          stock shall be conducted in accordance with the
          applicable Department of Treasury Regulations and
          generally accepted accounting and valuation procedures.
          The fair value of stock shall be determined without
          regard to any restriction other than a restriction
          which, by its terms, will never lapse, as provided in
          Section 422A(c)(10) of the Internal Revenue Code.

6.   PERIOD OF OPTION AND CERTAIN LIMITATIONS ON RIGHT TO EXERCISE.
     -------------------------------------------------------------

     (a)  Time Within Which Grant Must Be Made.
          ------------------------------------

          All options granted under this Plan shall be granted on
          or before October 25, 2005, and shall be evidenced by a
          Notice of Grant of Stock Option ("Notice of Grant")
          that shall be executed on behalf of Thermacore, and
          following the Merger, by a Stock Option Agreement
          executed on behalf of Modine.  The terms of the Notice
          of Grant shall be determined from time to time by the
          Committee consistent, however, with the terms of the
          Plan, and the terms of the Stock Option Agreement shall
          be consistent with the terms of the Notice of Grant and
          the Plan.

     (b)  Periods of Exercise of Options.
          ------------------------------

          An option shall be exercisable in whole or in part at
          such time or times as may be determined by the
          Committee and stated in the Notice of Grant, provided
          that no option shall be exercisable before the first
          anniversary of the date of the grant and that no option
          shall be exercisable after the expiration of five (5)
          years from the date the option is granted in the case
          of an option granted to a Ten Percent Shareholder or
          after the expiration of ten (10) years from the date
          the option is granted in all other cases, except as
          provided below:

          (i)  In the event that an employee who has been granted
               an option (hereinafter referred to as an
               "optionee") ceases to be employed by Modine,
               Thermacore or any subsidiary corporation of Modine
               or Thermacore for any reason other than death or
               disability, within the meaning of Section 22(c)(3)
               of the Internal Revenue Code, any option or
               options granted to him under the Plan which have
               not yet expired or been exercised shall not be
               exercisable after three (3) months from the date
               the optionee ceases to be employed; provided,

               however, that in the case of involuntary
               termination for cause, all options shall
               immediately become invalid.

          (ii) If an optionee ceases to be employed by Modine,
               Thermacore or any subsidiary corporation of Modine
               or Thermacore due to disability, within the
               meaning of Section 22(e)(3) of the Internal
               Revenue Code, any option or options granted to the
               optionee under the Plan which have not yet expired
               or been exercised shall not be exercisable after
               one (1) year from the date the optionee ceases to
               be employed.

         (iii) In the event that an optionee ceases to be
               employed by Modine, Thermacore or any subsidiary
               corporation of Modine or Thermacore by reason of
               his or her death, or dies within three (3) months
               after his voluntary termination, any option or
               options granted to the optionee under this Plan
               and not theretofore exercised or expired shall be
               exercisable by the estate of the optionee or by
               any person to whom the rights of the optionee
               shall have passed by will or by the laws of
               descent and distribution even if the date of
               exercise is within any time period prescribed by
               the Plan prior to which such option shall not be
               exercisable.

     (c)  Holder of Shares.
          ----------------

          No optionee or his legal representative, legatees, or
          distributees, as the case may be, will be, or will be
          deemed to be, a holder of any share subject to an
          option unless and until certificates of such shares are
          issued to him or them under the terms of the Plan.  No
          adjustment shall be made for dividends or other rights
          for which the record date is prior to the date such
          stock certificate is issued.

     (d)  Restrictions or Transferability.
          -------------------------------

          Each option granted under this Plan shall not be
          transferrable by the optionee otherwise than by will or
          the laws of descent and distribution, and shall be
          exercisable during the lifetime of the optionee only by
          the optionee.  Upon the death of an optionee, the
          person to whom the rights shall have passed will or by
          the laws of descent and distribution may exercise any
          options only in accordance with the provisions of
          Paragraph 6, subparagraph (b).  Except as permitted by
          the first sentence in this Paragraph, no option
          privileges thereby conferred shall be transferred,
          assigned, pledged, or hypothecated in any way (whether
          by operation of law or otherwise), and no such option,
          right, or privilege shall be subject to execution,
          attachment, or similar process.  Upon any attempt to

          transfer, assign, pledge, hypothecate, or otherwise
          dispose of the option, or of any right or privilege
          conferred thereby, contrary to the provisions hereof,
          or upon the levy of any attachment or similar process
          upon such option, right or privilege, the option and
          such rights and privileges shall immediately become
          null and void.

     (e)  Payment.
          -------

          Full payment for the shares of stock purchased upon the
          exercise of an option shall be made (i) in cash, or by
          check, bank draft or money order payable to the order
          of Modine, (ii) by delivering shares of stock of Modine
          of equivalent fair market value on the date the option
          is exercised, or (iii) by attestation (i.e., by
          affidavit identifying for delivery specific already-
          owned shares of Modine common stock having a fair
          market value on the date the option is exercised equal
          to the aggregate exercise price, but not actually
          delivering such shares to Modine).  No exercise of an
          option granted under this Plan shall be complete, and
          no share certificate issued, until full payment is
          received by Modine.

     (f)  Issuance of Certificates; Payment of Cash.
          -----------------------------------------

          Only whole shares of stock shall be issuable upon the
          exercise of options.  Any right to a fractional share
          shall be satisfied in cash.  Subject to the other
          provisions of this Plan, upon payment of the option
          price, a certificate for the number of whole shares and
          a check for the value on the date of exercise of any
          fractional share to which the optionee is entitled
          shall be delivered to such optionee.


     (g)  Date of Exercise.
          ----------------

          The date of exercise of an option shall be the date on
          which written notice of exercise, addressed to Modine
          at its main office to the attention of its Secretary,
          is hand-delivered, telecopied, or mailed first class,
          postage prepaid; provided, however, that Modine shall
          not be obliged to deliver any certificates for shares
          pursuant to the exercise of an option until the
          optionee shall have made payment in full of the option
          price of such shares.  Each such exercise shall be
          irrevocable when given.

     (h)  Prior Options.
          -------------

          No incentive stock option granted under this Plan shall
          be exercisable while there is outstanding in the hands
          of the optionee any incentive stock option (whether

          granted under this Plan or any other stock option plan
          established by Thermacore or a parent or subsidiary
          corporation of Thermacore or a predecessor corporation
          of any such corporations) which was granted prior to
          time to the incentive stock option then proposed to be
          exercised.  For purposes of the Plan, an incentive
          stock option shall be considered and treated as
          outstanding until such option is exercised in full or
          expires by reason of the lapse of time.

7.   RIGHTS AS SHAREHOLDERS.
     ----------------------

     An optionee shall have no rights as a shareholder with
     respect to any shares covered by his or her options until
     the date of the issuance of a stock certificate for such
     shares.

8.   CHANGES IN CAPITALIZATION.
     -------------------------

     In the event of a stock dividend, stock split,
     recapitalization, combination, subdivision, issuance of
     rights, or other similar corporate change, the Board shall,
     subject to the various restrictions of the Plan, make an
     appropriate proportional adjustment in the aggregate number
     of shares that may be subject to options, and the number of
     shares subject to, and the option price of, each then-
     outstanding option.  No adjustment shall be made for cash
     dividends or the issuance to stockholders of rights to
     subscribe for additional common stock or securities.

9.   MERGERS, DISPOSITIONS AND CERTAIN OTHER TRANSACTIONS.
     ----------------------------------------------------

     If, during the term of an option, Modine shall be merged
     into or consolidated with or otherwise combined with or
     acquired by another person or entity, or there is a divisive
     reorganization or a liquidation or partial liquidation of
     Modine, Modine may choose to take no action with regard to
     the options outstanding or to take any of the following
     courses of action:

     (a)  Not less than 15 days nor more than 60 days prior to
          any such transaction, all optionees shall be notified
          that their options shall expire on the 15th day after
          the date of such notice, in which event all optionees
          shall have the right to exercise all of their options
          prior to such new expiration date; or

     (b)  Modine shall provide in any agreement with respect to
          any such merger, consolidation, combination or
          acquisition that the surviving, new or acquiring
          corporation shall grant options to the optionees to
          acquire shares in such corporation with respect to
          which the excess of the fair value of the shares of
          such corporation immediately after the consummation of
          such merger, consolidation, combination or acquisition
          over the option price, shall not be greater than the

          excess of the value of the shares over the option price
          of options, immediately prior to the consummation of
          such merger, consolidation, combination or acquisition;
          or

     (c)  Modine shall take such other action as the Committee
          shall determine to be reasonable under the
          circumstances in order to permit optionees to realize
          the value of rights granted to them under the Plan.

10.  PLAN NOT TO AFFECT EMPLOYMENT.
     -----------------------------

     Neither the existence of the Plan nor the granting of any
     option thereunder shall confer upon any employee of
     Thermacore any right to continue in the employment of
     Thermacore.

11.  EFFECTIVE DATE AND TERM OF PLAN.
     -------------------------------

     The Plan became effective on October 25, 1995 and was
     adopted by Modine, and amended and restated in its entirety,
     effective April 27, 2001.  The Plan shall expire on October 25,
     2005, unless sooner terminated by the Board.

12.  AMENDMENT OF PLAN.
     -----------------

     The Board of Directors may at any time and from time to time
     make such amendments of this Plan (including the Notice of
     Grant and the Stock Option Agreement) as it shall deem
     advisable; provided, however, that no amendment of this Plan
     may, without the consent of the holder of an existing
     option, adversely affect his rights thereunder.

13.  EXPIRATION AND TERMINATION OF THE PLAN.
     --------------------------------------

     The Plan may be abandoned or terminated at any time by the
     Board except with respect to any options then outstanding
     under the Plan.


April 27, 2001
