                                (REVERSE OF NOTE)

                               MMH HOLDINGS, INC.

                        12% Exchange Debentures due 2009

            1. Interest.

            MMH HOLDINGS, Inc., a Delaware corporation (the "Company"), promises
to pay interest on the principal amount of this Note at the rate per annum shown
above. The Company will pay interest semi-annually on April 1 and October 1 of
each year (an "Interest Payment Date"), commencing the Interest Payment Date
following the date of issuance of this Note. Interest on the Notes will accrue
from the most recent date to which interest has been paid or, if no interest has
been paid, from the date of issuance of this Note. Interest will be computed on
the basis of a 360-day year of twelve 30-day months. Capitalized terms used
herein and not defined shall have the meanings given them in the Indenture.

            Notwithstanding anything herein to the contrary, on each Interest
Payment Date through and including April 1, 2003, the entire amount of the
interest payment on the Notes may be paid, at the option of the Company, in
additional Notes ("Secondary Notes") (valued at 100% of the principal amount
thereof). The Company may, at its option, pay cash in lieu of issuing any
Secondary Note to the extent the principal amount of such Secondary Note is not
an integral multiple of $1,000. The Company shall notify the Trustee of the
Company's election to pay interest in Secondary Notes not less than 5 days prior
to the Record Date for an Interest Payment Date. On each such Interest Payment
Date, the Trustee shall authenticate Secondary Notes for original issuance to
each holder of Notes on the preceding Record Date, as shown on the register of
the Notes, in the amount required to pay such interest. For purposes of
determining the principal amount of Secondary Notes to be issued in payment of
interest, the Company shall be entitled to aggregate as to each Holder the
principal amount of all Notes (including Secondary Notes) held of record by such
Holder.

            2. Method of Payment.

            The Company shall pay interest on this Note provided for in
Paragraph 1 above (except defaulted interest) to the person who is the
registered Holder of this Note at the close of business on March 15 or September
15 preceding the Interest Payment Date (whether or not such day is a business
day). A Holder must surrender this Note to a Paying Agent to collect principal
payments. The Company shall pay principal, premium, if any, and interest (to the
extent not paid in Secondary Notes) in money of the United States that at the
time of payment is legal tender for payment of public and private debts ("U.S.
Legal Tender"); provided, however, that the Company may pay principal, premium,
if any, and interest by check payable in such U.S. Legal Tender. The Company may
deliver any such interest payment (including any indirect payment made in
Secondary Notes) to the Paying Agent or to a Holder at the Holder's registered
address.


                                      A-3


            3. Paying Agent and Registrar.

            Initially, [      ] (the "Trustee") will act as Paying Agent and
Registrar. The Company may change any Paying Agent, Registrar without notice to
the Holders of the Notes. Neither the Company nor any of its subsidiaries or its
Affiliates may act as Paying Agent but may act as Registrar.

            4. Indenture.

            The Company issued the Notes under an Indenture, dated as of [     ]
(the "Indenture"), by and between the Company and the Trustee. The terms of this
Note include those stated in the Indenture and those made part of the Indenture
by reference to the Trust Indenture Act of 1939 (15 U.S.C. sections
77aaa-77bbbb) (the "TIA"), as in effect on the date of the Indenture until such
time as the Indenture is qualified under the TIA, and thereafter as in effect on
the date on which the Indenture is qualified under the TIA. This Note is subject
to all such terms, and Holders of this Note is referred to the Indenture and the
TIA for a statement of them. The Notes are limited in aggregate principal amount
to [$    ], plus any Secondary Notes issued as provided in paragraph 1 above and
the Indenture. Capitalized terms herein are used as defined in the Indenture
unless otherwise defined herein.

            5. Optional Redemption.

            The Notes will be redeemable, at the Company's option, in whole or
in part, at any time from time to time on or after April 1, 2003, at the
following Redemption Prices (expressed as percentages of the principal amount)
together, in each case with if redeemed during the twelve-month period
commencing on April of the years set forth below, plus, in each case, accrued
interest thereon to the date of redemption:

            Year                                              Percentage
            ----                                              ----------

            2005................................................102.000%
            2006 and thereafter.................................100.000%

            Notwithstanding the foregoing, the Company may redeem in the
aggregate all, but not less than all, of the Notes then outstanding at any time
prior to April 1, 2001, at a redemption price equal to 112.000% of the aggregate
principal amount so redeemed, plus accrued interest to the redemption date out

such redemption occurs within 90 days following the closing of any such Public
Equity Offering.

            6. Notice of Redemption.

            Notice of redemption will be mailed at least 30 days but not more
than 60 days before the Redemption Date to each Holder of Notes to be redeemed

                                      A-4


address. Notes in denominations of $1,000 or less may be redeemed only in whole.
The Trustee may select for redemption portions (equal to $1,000 or any integral
multiple thereof) of the principal of Notes that have denominations larger than
$1,000.

            If any Note is to be redeemed in part only, the notice of redemption
that relates to such Note shall state the portion of the principal amount
thereof to be redeemed. A new Note in a principal amount equal to the unredeemed
portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note. On and after the Redemption Date, interest
will cease to accrue on Notes or portions thereof called for redemption.

            7. Change of Control Offer.

            Upon the occurrence of a Change of Control, the Company will be
required, subject to certain limitations, to offer to purchase all of the
outstanding Notes at a purchase price equal to 101% of the principal amount
thereof plus accrued and unpaid interest, if any, to the date of repurchase.

            8. Limitation on Certain Asset Sales.

            The Company is subject to certain conditions, obligated to make an
offer to purchase Notes at 100% of their principal amount plus accrued and
unpaid interest to the date of repurchase with certain net cash proceeds of
certain sales or other dispositions of assets in accordance with the Indenture.

            9. Denominations; Transfer; Exchange.

            The Notes are in registered form, without coupons, in denominations
of $1,000 and integral multiples of $1,000; provided, however, that Secondary
Notes and Notes issued in exchange for the Series A Senior Preferred Stock may
be issued in denominations of less than $1,000. A Holder shall register the
transfer of or exchange Notes in accordance with the Indenture. The Registrar
may require a Holder, among other things, to furnish appropriate endorsements
and transfer documents and to pay certain transfer taxes or similar governmental
charges payable in connection therewith as permitted by the Indenture. The
Registrar need not register the transfer of or exchange any Notes during a
period beginning 15 days before the mailing of a redemption notice for any Notes
or portions thereof selected for redemption.

            [10. Persons Deemed Owners.

            The registered Holder of a Note shall be treated as the owner of it
for all purposes.]

            [10. The Global Note.

                                      A-5


rights under the Indenture with respect to this Global Note held on their behalf
by the Depository or the Trustee as its custodian, and the Depository may be
treated by the Company, the Trustee and any agent of the Company or the Trustee
as the absolute owner of this Global Note for all purposes. Notwithstanding the
foregoing, nothing herein shall (i) prevent the Company, the Trustee or any
agent of the Company or the Trustee, from giving effect to any written
certification, proxy or other authorization furnished by the Depository or (ii)
impair, as between the Depository and its Agent Members, the operation of
customary practices governing the exercise of the rights of a Holder of Notes.

            The Holder of this Global Note may grant proxies and otherwise
authorize any Person, including Agent Members and Persons that may hold
interests in this Global Note through Agent Members, to take any action which a
Holder of Notes is entitled to take under the Indenture or the Notes.

            Whenever, as a result of optional redemption by the Company, a
Change of Control Offer, an Excess Proceeds Offer or an exchange for Physical
Notes, this Global Note is redeemed, repurchased or exchanged in part, this
Global Note shall be surrendered by the Holder thereof to the Trustee who shall
cause an adjustment to be made to Schedule A hereof so that the principal amount
at Maturity of this Global Note will be equal to the portion not redeemed,
repurchased or exchanged and shall thereafter return this Global Note to such
Holder; provided that this Global Note shall be in a principal amount at
Maturity of $1,000 or an integral multiple of $1,000.]*

            11. Unclaimed Funds.

            If funds for the payment of principal, premium or interest remain

            The Company may be discharged from its obligations under the
Indenture and the Notes except for certain provisions thereof, and may be

conditions specified in the Indenture.

            13. Amendment; Supplement; Waiver.

            Subject to certain exceptions, the Indenture or the Notes may be
modified, amended or supplemented by the Company and the Trustee with the
consent of the Holders of at least a majority in aggregate principal amount of
the Notes then outstanding, and any existing Default or Event of Default or
compliance with any provision may be waived with the consent of the Holders of a
majority in aggregate principal amount of the Notes then outstanding. Without
notice to or consent of any Holder, the Company and the Trustee may amend or
supplement the 


                                      A-6


Indenture or the Notes to, among other things, cure any ambiguity, defect or
inconsistency, provide for uncertificated Notes in addition to or in place of
certificated Notes or comply with any requirements of the Commission in
connection with the qualification of the Indenture under the TIA, or make any
other change that does not materially adversely affect the rights of any Holder
of a Note.

            14. Restrictive Covenants.

            The Indenture contains certain covenants that, among other things,
limit the ability of the Company and its Restricted Subsidiaries to make
Restricted Payments, to incur Indebtedness, to issue Preferred Stock or other
Capital Stock of Restricted Subsidiaries, to sell assets, to permit restrictions
on dividends and other payments by Restricted Subsidiaries to the Company, to
consolidate, merge or sell all or substantially all of its assets or to engage
in transactions with Affiliates. The limitations are subject to a number of
important qualifications and exceptions.

            15. Defaults and Remedies.

            If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in aggregate principal amount of Notes then outstanding
may declare all the Notes to be due and payable immediately in the manner and
with the effect provided in the Indenture. Holders of Notes may not enforce the
Indenture or the Notes except as provided in the Indenture. The Trustee is not
obligated to enforce the Indenture or the Notes unless it has received indemnity
satisfactory to it. The Indenture permits, subject to certain limitations
therein provided, Holders of a majority in aggregate principal amount of the
Notes then outstanding to direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Holders of Notes notice of any continuing
Default or Event of Default (except a Default in payment of principal, premium
or interest, including an accelerated payment) if it determines that withholding
notice is in their interest.

            16. Trustee Dealings with Company.

            The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Notes and may otherwise deal with
the Company, its Subsidiaries or their respective Affiliates as if it were not
the Trustee.

            17. No Recourse Against Others.

            No stockholder, director, officer, employee or incorporator, as
such, of the Company shall have any liability for any obligation of the Company
under the Notes or the Indenture or for any claim based on, in respect of or by
reason of, such obligations or their creation. Each Holder of a Note by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for the issuance of the Notes.

            18. Authentication.


                                      A-7

agent signs the certificate of authentication on this Note.
