                               FOURTH AMENDMENT TO
                       AMENDED AND RESTATED CLASS B RIGHTS
                                   AGREEMENT

       THIS FOURTH AMENDMENT to the Amended and Restated Class B Rights
Agreement dated April 22, 1992, as amended (as so amended, the "Existing Class B
Agreement"), is dated as of August 22, 2001 and is between TECUMSEH PRODUCTS
COMPANY, a Michigan corporation (the "Company"), and STATE STREET BANK AND TRUST
COMPANY, N.A., as Class A Rights Agent (the "Agent").

       WHEREAS, Section 26 of the Existing Class B Agreement entitles the
Company at any time prior to the Distribution Date (as therein defined) to amend
any provisions of the Existing Class B Agreement and requires the Agent, if
directed by the Company, to execute any such amendment upon the delivery of a
certificate from an appropriate officer of the Company which states that it is
in compliance with Section 26 (a "compliance certificate"); and

       WHEREAS, the Board of Directors of the Company has authorized and
approved the amendments to the Existing Class B Agreement hereafter set forth in
this Fourth Amendment and has directed the execution hereof, and a compliance
certificate concerning this Fourth Amendment has been delivered to the Agent;

       NOW, THEREFORE, in consideration of the foregoing and pursuant to Section
26 of the Existing Class B Agreement, the parties hereby agree as follows:

       1. Amendment of Definition of "Acquiring Person." The definition of
"Acquiring Person" in Section 1 of the Existing Class B Agreement is hereby
amended to read in its entirety as follows:

              "Acquiring Person" shall mean any Person who or which shall be the
       Beneficial Owner of 10% or more of the shares of Class B Stock then
       outstanding, but shall not include:

                  (i) the Company;

                  (ii) any Subsidiary of the Company;

                  (iii) any employee benefit plan of the Company or of any
              Subsidiary of the Company or any trustee or fiduciary with respect
              to any such plan acting in such capacity;

                  (iv) any Grandfathered Person, unless such Grandfathered
              Person after April 22, 1992 becomes the Beneficial Owner of more
              than the Grandfathered Percentage of the Class B Stock then
              outstanding;


<PAGE>   2

                  (v) any Person who or which becomes the Beneficial Owner of
              10% (or, if applicable, the Grandfathered Percentage) or more of
              the shares of Class B Stock then outstanding as a result of a
              reduction in the number of shares of Class B Stock outstanding due
              to the repurchase of shares of Class B Stock by the Company unless
              and until such Person, after becoming aware that such Person has
              become the Beneficial Owner of 10% (or, if applicable, the
              Grandfathered Percentage) or more of the then outstanding shares
              of Class B Stock, acquires beneficial ownership of additional
              shares of Class B Stock representing 1% or more of the shares of
              Class B Stock then outstanding; or

                  (vi) any such Person who or which has reported or is permitted
              to report such ownership (but less than 20%) on Schedule 13G under
              the Exchange Act (or any comparable or successor report), or on
              Schedule 13D under the Exchange Act (or any comparable or
              successor report) which Schedule 13D does not state any intention
              to or reserve the right to control or influence the management or
              policies of the Company or engage in any of the actions specified
              in Item 4 of such Schedule (other than the disposition of the
              Class B Stock). Within ten Business Days after being requested by
              the Company, such Person shall certify to the Company that such
              Person acquired beneficial ownership of shares of Class B Stock
              representing 10% or more of the outstanding Class B Stock
              inadvertently or without knowledge of the terms of the Class B
              Rights. If such Person, having been requested to so certify as
              aforesaid, fails to do so within ten Business Days, then such
              Person shall become an Acquiring Person immediately after such ten
              Business Day period. If such Person, after so certifying, acquires
              beneficial ownership of additional shares of Class B Stock while
              the Beneficial Owner of 10% or more of the shares of Class B Stock
              then outstanding, then such Person shall become an Acquiring
              Person immediately following the date on which the Company's Board
              of Directors shall adopt a resolution to that effect.

       2. Amendment of Section 11(a)(ii)(B). Section 11(a)(2)(B) of the Existing
Class B Agreement is hereby amended to read in its entirety as follows:

           (B) any Acquiring Person shall become the Beneficial Owner of 15%
       (or, if such Person is a Grandfathered Person, the greater of the
       Grandfathered Percentage or 15%) or more of the shares of Class B Stock
       then outstanding, other than pursuant to any transaction set forth in
       Section 13(a) hereof; or

       3. Amendment of Section 11(d). The first sentence of Section 11(d) of the
Existing Class B Agreement is hereby amended to read as follows:

           (d) For the purpose of any computation hereunder, the "current market
       price" per share of Class B Stock on any date shall be deemed to be the


                                      -2-
<PAGE>   3

       arithmetic mean of the average of the daily closing prices per share of
       the Class A Stock and the average of the daily closing prices per share
       of the Class B Stock for the ten consecutive Trading Days (as such term
       is hereinafter defined) immediately prior to such date; provided,
       however, if prior to the expiration of such requisite ten Trading Day
       period the issuer announces either (A) a dividend or distribution on such
       shares payable in such shares or securities convertible into such shares
       (other than the Class B Rights or rights issued under the Company's Class
       A Rights Agreement dated as of April 22, 1992, as amended from time to
       time), or (B) any subdivision, combination or reclassification of such
       shares, then, following the ex-dividend date for such dividend or the
       record date for such subdivision, as the case may be, the "current market
       price" shall be properly adjusted to take into account such event.

       4. Amendment of Summary of Rights. Exhibit B to the Existing Class B
Agreement (Summary of Rights to Purchase Class B Stock) is hereby amended to
read in its entirety as set forth in Annex A to this Fourth Amendment.

       5. Affirmation. Except as specifically amended herein, the Existing Class
B Agreement shall remain in full force and effect as existing prior to the date
hereof.

       IN WITNESS WHEREOF, the parties hereto have caused this Fourth Amendment
to be duly executed, all as of the date first above written.

                                     ANNEX A


                                                                       EXHIBIT B


                   SUMMARY OF RIGHTS TO PURCHASE CLASS B STOCK

       Pursuant to a Class B Rights Agreement amended and restated in 1992,
Tecumseh Products Company (the "Company") distributed one Class B Right for each
share of Class B Stock issued by the Company. Each Class B Right entitles the
registered holder, subject to the terms of the Class B Rights Agreement, to
purchase from the Company one share of Class B Stock at a specified purchase
price.

       The Class B Rights are issued pursuant to an Amended and Restated Class B
Rights Agreement dated as of April 22, 1992, as amended, between the Company and
State Street Bank and Trust Company, N.A., as successor Class B Rights Agent.
This summary does not purport to be complete and is qualified in its entirety by
reference to all the provisions of the Class B Rights Agreement, including its
definition of certain terms. The Class B Rights Agreement is incorporated in
this summary by reference. Copies of the Class B Rights Agreement and all
amendments to that Agreement have been filed with the Securities and Exchange
Commission and are available free of charge from the Company.

       Each Class B Right entitles the registered holder, subject to the terms
of the Class B Rights Agreement, to purchase from the Company one share of Class
B Stock at a purchase price of $180.00 per share, subject to adjustment (the
"Purchase Price"). The Purchase Price is payable in cash or by certified or bank
check or money order payable to the order of the Company.

       The Class B Rights currently are attached to all certificates
representing shares of outstanding Class B Stock. Class B Rights will also be
attached to all certificates representing shares of Class B Stock issued in the
future until the Distribution Date. Initially, no separate Class B Rights
Certificates will be distributed. Until the Distribution Date, the Class B
Rights will be evidenced by the certificates representing Class B Stock and will
be transferred with and only with those certificates. The Class B Rights are not
exercisable until the Distribution Date and will expire at the close of business
on August 25, 2009, unless earlier redeemed by the Company as described below.

       The Class B Rights will separate from the Class B Stock on the
Distribution Date. The Distribution Date will occur upon the earlier of (i) ten
business days following a public announcement (the "Stock Acquisition Date")
that a person or group of persons (an "Acquiring Person") has acquired 10% (or,
if such person or group is a "Grandfathered Person," the "Grandfathered
Percentage") or more of


<PAGE>   5

the then outstanding shares of Class B Stock other than as a result of
repurchases of Class B Stock by the Company or certain inadvertent actions by
institutional or certain other shareholders, or (ii) ten business days (or a
later date determined by the Board of Directors) following the commencement,
without Board approval, of a tender or exchange offer that would result in a
person or group owning 10% or more of the then outstanding shares of Class B
Stock. Any person or group that owned 5% or more of the Class B Stock
outstanding on April 22, 1992 (a "Grandfathered Person") will not be an
Acquiring Person unless the percentage of outstanding shares of Class B Stock
owned by that Grandfathered Person subsequently exceeds twice the percentage
owned on April 22, 1992, plus an additional 1% (the "Grandfathered Percentage").
An announcement by the Company will only give rise to the Stock Acquisition Date
if the Company expressly states in the announcement that it will do so.

       After the Distribution Date, Class B Rights Certificates will be mailed
to holders of record of Class B Stock on the Distribution Date. From that point
on, the separate Class B Rights Certificates alone will represent the Class B
Rights.

       If (i) the Company survives a merger with an Acquiring Person and shares
of Class B Stock remain outstanding, or (ii) any Acquiring Person becomes the
owner of 15% (or, if such person is a Grandfathered Person, the greater of 15%
or the Grandfathered Percentage) or more of the outstanding shares of Class B
Stock (other than pursuant to a transaction described in the next paragraph), or
(iii) an Acquiring Person engages in one or more "self-dealing" transactions as
set forth in the Class B Rights Agreement, or (iv) the Company is a party to any
transaction which results in an Acquiring Person's ownership interest being
increased by more than 1% (other than a transaction described in the next
paragraph), then, in each such case, each Class B Right will thereafter
represent the right to receive, upon exercise, shares of Class B Stock (or, in
certain circumstances, shares of Class B Stock and cash, property, or other
securities of the Company) having a value (based on the current market price)
equal to two times the Purchase Price of the Class B Right. However, all Class B
Rights that are owned by any Acquiring Person will be null and void.

       If, at any time following the Stock Acquisition Date, (i) the Company
merges into any other person, (ii) any person merges into the Company and in
connection with the merger all or part of the Class B Stock is converted or
exchanged for cash or property, or securities of any other person, or (iii) 50%
or more of the Company's assets or earning power is sold or transferred, each
holder of a Class B Right (except Class B Rights which previously have been
voided as

                                      -2-
<PAGE>   6

described above) will have the right to receive, upon exercise, common stock of
the Acquiring Person having a value (based on the current market price) equal to
two times the Purchase Price of the Class B Right.

       For purposes of the calculations described above, the current market
price of the Class B Stock will be considered to be the average of the daily
closing prices of the Class A Stock and the Class B Stock over a period of ten
consecutive trading days.

       The Purchase Price payable, and the number of shares of Class B Stock
issuable, upon exercise of the Class B Rights are subject to adjustment from
time to time to prevent dilution. Those circumstances are set forth in detail in
the Class B Rights Agreement. With certain exceptions, no adjustment in the
Purchase Price will be required until cumulative adjustments amount to at least
1% of the Purchase Price. The Company is not required to issue fractional
shares. Instead, it may make a cash adjustment based on the market price of the
Class B Stock prior to the date of exercise.

       For ten business days following the Stock Acquisition Date, the Company's
Board of Directors may redeem all the Class B Rights at a price of one-fourth of
one cent ($.0025) per Class B Right, subject to adjustment (the "Redemption
Price"). The Redemption Price is payable, at the election of the Board, in cash
or shares of Class B Stock. Immediately upon action of the Board of Directors
ordering the redemption of the Class B Rights, the Class B Rights will terminate
and the holders of Class B Rights will only have a right to receive the
Redemption Price.

       Until a Class B Right is exercised, the holder of the Right will have no
rights as a shareholder of the Company with respect to that Right (but the
holder will have rights as a shareholder with respect to the Class B Stock that
the Class B Right is attached to). The distribution of the Class B Rights was
not taxable to shareholders or to the Company. However, Class B shareholders
may, depending on the circumstances, recognize taxable income if the Class B
Rights become exercisable.

       Any of the provisions of the Class B Rights Agreement may be amended at
any time prior to the Distribution Date. After the Distribution Date, the Class
B Rights Agreement may be amended to cure an ambiguity, defect, or
inconsistency, to make changes that do not adversely affect the interests of
holders of Class B Rights Certificates (excluding the interests of any Acquiring
Person), or to shorten or lengthen any time period. However, no amendment may

                                      -3-
<PAGE>   7

be made to lengthen the time period governing redemption when the Class B Rights
are not redeemable or to lengthen any other time period unless it is for the
purpose of protecting, enhancing, or clarifying the rights of and/or the
benefits to the holders of Class B Rights.
