     MascoTech, Inc. and its consolidated subsidiaries manufacture products
principally for the original equipment and aftermarket transportation markets.
Transportation-related products are manufactured utilizing a variety of
metalworking and other process technologies. Although published industry
statistics are generally not available, the Company believes that it is a
leading independent producer of many of the industrial component parts that it
produces using cold, warm or hot forming processes. In addition to its
manufacturing activities, the Company provides design and engineering services
primarily for the automotive, heavy truck and aerospace industries. The Company
also manufactures architectural and other specialty industrial products.
 
     The Company's executive offices are located at 21001 Van Born Road, Taylor,
Michigan 48180, and the telephone number is (313) 274-7405. Except as the

                                USE OF PROCEEDS
 
     The Company expects to apply substantially all of the net proceeds from
sales of Securities by the Company to its general funds to be used for general
corporate purposes, including working capital, repayment of debt and
expenditures for development of activities in which it is now engaged or
investment in and development of activities in which it is not currently
engaged. In this regard, the Company maintains an active acquisition effort and
is frequently engaged in discussions with respect to acquisition opportunities.
Proceeds from sales of Securities by the Company could be applied directly or
indirectly to such acquisitions. Funds not required immediately for any of the
foregoing purposes may be invested in marketable securities. The Company intends
to use the proceeds from the offering described in the Prospectus Supplement as
set forth in the Prospectus Supplement under the caption "Use of Proceeds".
 
                           DESCRIPTION OF SECURITIES
 
     The Securities offered hereby will be issued under an Indenture dated as of
                   (hereinafter referred to as the "Indenture") between the
Company and The First National Bank of Chicago, as Trustee (hereinafter referred
to as the "Trustee"). The following statements are subject to the detailed
provisions of the Indenture, a copy of which is filed as an exhibit to the
registration statement covering the Securities. Whenever references are made to
particular provisions of the Indenture, such provisions are incorporated by
reference as part of the statements made and such statements are qualified in
their entirety by such references. Certain defined terms are capitalized.
References in italics are to the Indenture. As used in the Indenture, the term
"Company" means MascoTech, Inc. without reference to its consolidated
subsidiaries.
 
GENERAL
 
     The Indenture does not limit the amount of Securities which may be issued
thereunder. The Prospectus Supplement sets forth the following terms, where
applicable, of the Securities in respect of which this Prospectus is delivered:
(1) the title of such Securities; (2) any limit upon the aggregate principal
amount of such Securities; (3) the date or dates on which the principal of and
premium, if any, on such Securities are payable; (4) the rate or rates at which
such Securities shall bear interest, if any, or the method by which such
interest may be determined, the date or dates from which such interest shall
accrue, the interest payment dates on which such interest shall be payable and
the record dates for the determination of holders to whom interest is payable;
(5) the place or places where the principal of, and premium, if any, and any
interest on such Securities shall be payable; (6) the price or prices at which,
the period or periods within which and the terms and conditions upon which such
Securities may be redeemed, in whole or in part, at the option of the Company
pursuant to any sinking fund or otherwise; (7) the obligation, if any, of the
Company to redeem, purchase or repay such Securities pursuant to any sinking
fund or analogous provisions or at the option of a holder thereof and the price
or prices at which the period or periods within which and the terms and
conditions upon which such Securities shall be redeemed, purchased or repaid, in
whole or in part, pursuant to such obligation; (8) the right, if any, of the
Company to discharge or limit the Indenture with respect to such Securities
prior to maturity; (9) if other than denominations of $1,000 and any multiple
thereof, the denominations in which such Securities shall be issuable; (10) if
other than the principal amount thereof, the
 
                                        3
<PAGE>   5
 
portion of the principal amount of such Securities which shall be payable upon
declaration of acceleration of the maturity thereof or which shall be provable
in bankruptcy; (11) any additional Events of Default; (12) any trustees,
authenticating or paying agents, transfer agents or registrars with respect to
such Securities; (13) if other than the coin or currency in which such
Securities are denominated, the coin or currency, including composite

Securities, in a coin or currency other than that in which such Securities are
denominated, the period or periods within which, and the terms and conditions
upon which, such election may be made; (15) if payment of principal of or
interest on such Securities will be determined with reference to an index, the
manner in which such determination shall be made; (16) whether and under what
circumstances the Company will pay additional amounts on such Securities held by
a person who is not a U.S. person and, if so, whether the Company will have the
option to redeem such Securities rather than pay such additional amounts; (17)
if such Securities shall be issued in whole or in part in the form of one or
more Registered Global Securities (as described below), and, in such case, the
depositary for such Registered Global Security or Securities; (18) if such
Securities are to be issued in definitive form only upon receipt of certain
documents or satisfaction of other conditions, the form and terms of such
documents or conditions; and (19) such other terms of such Securities as are not
inconsistent with the provisions of the Indenture. (Section 2.03)
 
     The Securities offered hereby will be issued only in fully registered form
without coupons and, unless otherwise specified in the Prospectus Supplement, in
denominations of $1,000 and any multiple thereof. No service charge will be made
for any transfer or exchange of the Securities, but the Company or the Trustee
may require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith. (Sections 2.05 and 2.07) Principal,
premium, if any, and interest, if any, will be payable and the Securities
offered hereby (other than Registered Global Securities as described below) will
be transferable at the corporate trust office or agency of the Trustee in New
York, New York, provided that payment of interest, if any, may be made at the
option of the Company by check mailed to the address of the person entitled
thereto as it appears in the registry books of the Company. (Sections 3.01 and
3.02)
 
     Some of the Securities may be issued as discounted Securities (bearing no
interest or interest at a rate which at the time of issuance is below market
rates) to be sold at a substantial discount below their stated principal amount.
Federal income tax consequences and other special considerations applicable to
any such discounted Securities are described in the Prospectus Supplement with
respect to any such Securities.
 
     Except as may be set forth in the Prospectus Supplement, the Indenture does
not contain any covenants or provisions which afford holders of Securities
protection in the event of a highly leveraged transaction.
 
GLOBAL SECURITIES
 
     The registered Securities of a series may be issued in the form of one or
more fully registered global Securities (a "Registered Global Security") that
will be deposited with a depositary (a "Depositary") or with a nominee for a
Depositary identified in the Prospectus Supplement relating to such series and
registered in the name of the Depositary or a nominee thereof. In such case, one
or more Registered Global Securities will be issued in a denomination or
aggregate denominations equal to the portion of the aggregate principal amount
of outstanding registered Securities of the series to be represented by such
Registered Global Security or Registered Global Securities. Unless and until it
is exchanged in whole or in part for Securities in definitive registered form, a
Registered Global Security may not be transferred except as a whole by the
Depositary for such Registered Global Security to a nominee of such Depositary
or by a nominee of such Depositary to such Depositary or another nominee of such
Depositary or by such Depositary or any such nominee to a successor of such
Depositary or a nominee of such successor.
 
     The specific terms of the depositary arrangement with respect to any
portion of a series of Securities to be represented by a Registered Global
Security will be described in the Prospectus Supplement relating to such series.
The Company anticipates that the following provisions will apply to all
depositary arrangements.
 
     Ownership of beneficial interests in a Registered Global Security will be
limited to persons that have accounts with the Depositary for such Registered
Global Security ("participants") or persons that may hold interests through
participants. Upon the issuance of a Registered Global Security, the Depositary
for such
 
                                        4
<PAGE>   6
 
Registered Global Security will credit, on its book-entry registration and
transfer system, the participants' accounts with the respective principal
amounts of the Securities represented by such Registered Global Security
beneficially owned by such participants. The accounts to be credited will be
designated by the dealers, underwriters or agents participating in the
distribution of such Securities. Ownership of beneficial interests in such
Registered Global Security will be shown on, and the transfer of such ownership
interests will be effected only through, records maintained by the Depositary
for such Registered Global Security (with respect to interests of participants)
and on the records of participants (with respect to interests of persons holding
through participants). The laws of some states may require that certain
purchasers of securities take physical delivery of such securities in definitive
form. Such limits and such laws may impair the ability to own, transfer or
pledge beneficial interests in Registered Global Securities.
 
     So long as the Depositary for a Registered Global Security, or its nominee,
is the registered owner of such Registered Global Security, such Depositary or
such nominee, as the case may be, will be considered the sole owner or holder of
the Securities represented by such Registered Global Security for all purposes
under the Indenture. Except as set forth below, owners of beneficial interests
in a Registered Global Security will not be entitled to have the Securities
represented by such Registered Global Security registered in their names, and
will not receive or be entitled to receive physical delivery of such Securities
in definitive form and will not be considered the owners or holders thereof
under the Indenture. Accordingly, each person owning a beneficial interest in a
Registered Global Security must rely on the procedures of the Depositary for
such Registered Global Security and, if such person is not a participant, on the
procedures of the participant through which such person owns its interest, to
exercise any rights of a holder under the Indenture. The Company understands
that under existing industry practices, if the Company requests any action of
holders or if any owner of a beneficial interest in a Registered Global Security
desires to give or take any action which a holder is entitled to give or take
under the Indenture, the Depositary for such Registered Global Security would
authorize the participants holding the relevant beneficial interests to give or
take such action, and such participants would authorize beneficial owners owning
through such participants to give or take such action or would otherwise act
upon the instruction of beneficial owners holding through them.
 
     Payments of principal of, premium, if any, and any interest on Securities
represented by a Registered Global Security registered in the name of a
Depositary or its nominee will be made to such Depositary or its nominee, as the
case may be, as the registered owner of such Registered Global Security. None of
the Company, the Trustee or any other agent of the Company or agent of the
Trustee will have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests in
such Registered Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.
 
     The Company expects that the Depositary for any Securities represented by a
Registered Global Security, upon receipt of any payment of principal, premium,
if any, or any interest in respect of such Registered Global Security, will
immediately credit participants' accounts with payments in amounts proportionate
to their respective beneficial interests in such Registered Global Security as
shown on the records of such Depositary. The Company also expects that payments
by participants to owners of beneficial interests in such Registered Global
Security held through such participants will be governed by standing customer
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name," and
will be the responsibility of such participants.
 
     If the Depositary for any Securities represented by a Registered Global
Security notifies the Company that it is at any time unwilling or unable to
continue as Depositary or ceases to be a clearing agency registered under the
1934 Act, and a successor Depositary registered as a clearing agency under the
1934 Act is not appointed by the Company within 90 days, the Company will issue
such Securities in definitive form in exchange for such Registered Global
Security. In addition, the Company may at any time and in its sole discretion
determine not to have any of the Securities of a series represented by one or
more Registered Global Securities and, in such event, will issue Securities of
such series in definitive form in exchange for all of the Registered Global
Security or Registered Global Securities representing such Securities. Any
Securities issued in definitive form in exchange for a Registered Global
Security will be registered in such name or names as the Depositary shall

LIMITATION ON LIENS
 
     The Company covenants that, so long as any of the Securities remains
outstanding, it will not, nor will it permit any Consolidated Subsidiary to,
issue, assume or guarantee any debt for money borrowed or any Funded Debt
(herein referred to as "Debt") if such Debt is secured by a mortgage (as defined
in the Indenture) upon any Principal Property or upon any shares of stock or
indebtedness of any Consolidated Subsidiary which owns or leases any Principal
Property (whether such Principal Property, shares of stock or indebtedness are
owned on the date of the Indenture or are thereafter acquired) without in any
such case effectively providing that the Securities (together with, if the
Company shall so determine, any other indebtedness of or guarantees by the
Company or such Consolidated Subsidiary ranking equally and ratably with such
Debt and then existing or thereafter created) shall be secured equally and
ratably with such Debt, except that the foregoing restrictions shall not apply
to (i) mortgages on property, shares of stock or indebtedness of any corporation
existing at the time such corporation becomes a Consolidated Subsidiary; (ii)
mortgages on property existing at the time of acquisition thereof, or to secure
Debt incurred for the purpose of financing all or any part of the purchase price
of such property, or to secure any Debt incurred prior to, at the time of, or
within 120 days after the later of the acquisition, completion of construction
or improvement or the commencement of commercial operation of such property,
which Debt is incurred for the purpose of financing all or any part of the
purchase price thereof or construction or improvements thereon; (iii) mortgages
securing Debt owing by any Consolidated Subsidiary to the Company or another
Consolidated Subsidiary; (iv) mortgages on property of a corporation existing at
the time such corporation is merged or consolidated with the Company or a
Consolidated Subsidiary or at the time of a sale, lease or other disposition of
the properties of a corporation or firm as an entirety or substantially as an
entirety to the Company or a Consolidated Subsidiary, provided that no such
mortgage shall extend to any other Principal Property of the Company or any
Consolidated Subsidiary or any shares of capital stock or any indebtedness of
any Consolidated Subsidiary which owns or leases a Principal Property; (v)
mortgages on property of the Company or a Consolidated Subsidiary in favor of
the United States of America, any State thereof or any department, agency or
instrumentality thereof, or any other country, or any political subdivision of
any thereof, to secure payments pursuant to any contract or statute (including
Debt of the pollution control or industrial revenue bond type) or to secure any
indebtedness incurred for the purpose of financing all or any part of the
purchase price or the cost of construction of the property subject to such
mortgages; or (vi) certain extensions, renewals or replacements (or successive
extensions, renewals or replacements), in whole or in part, of mortgages
existing at the date of the Indenture or any mortgage referred to in the
foregoing clauses (i) through (v), inclusive. (Section 3.05(a))
 
     Notwithstanding the above, the Company and one or more Consolidated
Subsidiaries may, without securing the Securities, issue, assume or guarantee
secured Debt which would otherwise be subject to the foregoing restrictions,
provided that after giving effect thereto the total of the aggregate amount of
such Debt then outstanding (not including secured Debt permitted under the
foregoing exceptions) and the aggregate amount of Attributable Debt in respect
of sale and leaseback arrangements at such time does not exceed 5% of
Consolidated Net Tangible Assets, determined as of a date not more than 90 days
prior thereto. (Section 3.05(b))
 
LIMITATION ON SALES AND LEASEBACKS
 
     The Company covenants that it will not, and will not permit any
Consolidated Subsidiary to, enter into any sale and leaseback arrangement,
except for a lease for a term of not more than three years and except for a
lease between the Company and a Consolidated Subsidiary or between Consolidated
Subsidiaries, involving any Principal Property unless (i) the Company or such
Consolidated Subsidiary would be entitled pursuant to Section 3.05 of the
Indenture to issue, assume or guarantee Debt secured by a mortgage upon the
property involved at least equal in amount to the Attributable Debt in respect
of such arrangement without equally and ratably securing the Securities or (ii)
the Company or a Consolidated Subsidiary within 120 days of the
 
                                        6
<PAGE>   8
 
effective date of any such arrangement applies an amount equal to the greater of
the net proceeds of the sale of the Principal Property so leased or the fair
market value of such Principal Property to the retirement, other than any
mandatory retirement or by way of payment at maturity, of Funded Debt of the
Company or any Consolidated Subsidiary, other than Funded Debt owned by the
Company or any Consolidated Subsidiary and other than Funded Debt which is
subordinated in payment of principal or interest to the Securities, or, in lieu
of such retirement, delivers Securities to the Trustee for cancellation.
(Section 3.06)
 
CONSOLIDATION, MERGER OR SALE OF ASSETS
 
     The Company covenants that it will not consolidate or merge with or into
any other corporation and will not sell or convey its property as an entirety,
or substantially as an entirety, to another corporation if, as a result thereof,
any Principal Property (or any shares of stock or indebtedness of any
Consolidated Subsidiary owning any Principal Property) would become subject to a
mortgage, unless either (i) such mortgage could be created pursuant to Section
3.05 of the Indenture without equally and ratably securing the Securities or
(ii) the Securities shall be secured prior to the Debt secured by such mortgage.
(Section 9.03)

yield to maturity at the time of issuance of any Original Issue Discount
Securities determined on a weighted average basis compounded semi-annually) of
the total obligations of the lessee for rental payments during the remaining
term of the lease included in such arrangement (including any period for which
such lease has been extended or may, at the option of the lessor, be extended)
or until the earliest date on which the lessee may terminate such lease upon
payment of a penalty (in which case the rental payment shall include such
penalty), after excluding all amounts required to be paid on account of
maintenance and repairs, insurance, taxes, assessments, water and utility rates
and similar charges; provided, however, that there shall not be deemed to be any
Attributable Debt in respect of a sale and leaseback arrangement if (a) such
arrangement does not involve a Principal Property, (b) the Company or a
Consolidated Subsidiary would be entitled pursuant to the provisions of Section
3.05(a) of the Indenture to issue, assume or guarantee Debt secured by a
mortgage upon the property involved in such arrangement without equally and

intangibles and (c) all investments in any Subsidiary other than a Consolidated

Subsidiaries. (Section 1.01)
 
     "Funded Debt" is defined to mean indebtedness maturing more than 12 months

months but renewable or extendible at the option of the borrower beyond 12
months from the date of such determination (i) for money borrowed or (ii)
incurred in connection with the acquisition of real or personal property, stock,
debt or other assets (to the extent that any acquisition indebtedness is
represented by any notes, bonds, debentures or similar evidences of
indebtedness), for which the Company or any Consolidated Subsidiary is directly
or contingently liable or which is secured by property of the Company or a
Consolidated Subsidiary. (Section 1.01)

1.01)
 
DEFEASANCE
 
     If permitted by the terms of any series of Securities, the Company may
terminate certain of its obligations under the Indenture with respect to such
series, including its obligations to comply with the restrictive covenants
described herein, on the terms and subject to the conditions contained in the
Indenture, by depositing in trust with the Trustee money or obligations of, or
guaranteed by, the United States sufficient to pay the principal of, premium, if
any, and interest on the Securities of such series to maturity (or earlier
redemption). (Section 10.01) The Prospectus Supplement sets forth the defeasance
rights, if any, of the Company provided by the terms of the Securities in
respect of which this Prospectus is delivered.
 
EVENTS OF DEFAULT, WAIVER AND NOTICE
 
     As to each series of Securities, an Event of Default is defined in the
Indenture as being: default for 30 days in payment of any interest on the
Securities of that series; default in payment of principal or premium, if any,
on the Securities of that series when due either at maturity, upon redemption,
by declaration or otherwise; default by the Company in the performance of any
other of the covenants in the Indenture (other than a covenant included in the
Indenture solely for the benefit of a series of Securities other than that
series) which shall not have been remedied for a period of 90 days after notice;
and certain events of bankruptcy, insolvency and reorganization of the Company.
(Section 4.01) The Indenture provides that the Trustee may withhold notice to
the holders of the Securities of any default (except in payment of principal of
or premium, if any, or interest on the Securities) if the Trustee considers it
in the interest of the holders of the Securities to do so. (Section 4.08)
 
     The Indenture provides that, (i) if an Event of Default due to the default
in payment of principal, interest or premium on any series of Securities or due
to the default in the performance, or breach, of any covenant set forth
exclusively in the terms of such series of Securities established as
contemplated in the Indenture shall have occurred and be continuing, either the
Trustee or the holders of 33 percent in principal amount of the Securities of
such series then outstanding may declare the principal of all Securities of such
series (or, if the Securities of such series are issued as Original Issue
Discount Securities, such portion of the principal amount as may be specified in
the terms of such series) and interest accrued, if any, thereon to be due and
payable immediately and (ii) if an Event of Default resulting from a default in
the performance of any other of the covenants or agreements in the Indenture and
certain events of bankruptcy, insolvency and reorganization of the Company shall
have occurred and be continuing, either the Trustee or the holders of 33 percent
in principal amount of all Securities then outstanding (treated as one class)
may declare the principal of all
 
                                        8
<PAGE>   10
 
Securities (or, if any Securities are issued as Original Issue Discount
Securities, such portion of the principal amount as may be specified in the
terms of such Securities) and interest accrued thereon to be due and payable
immediately, but upon certain conditions such declarations may be annulled and
past defaults may be waived (except a continuing default in payment of principal
of or interest or premium on the Securities) by the holders of a majority in
principal amount of the Securities of such series (or of all series, as the case
may be) then outstanding. (Section 4.01)
 
     The holders of a majority in principal amount of the Securities of any or
all series at the time outstanding shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee under the Indenture. Notwithstanding the foregoing, the Trustee shall
have the right to decline to follow any such direction if the Trustee is advised
by counsel that the action so directed may not lawfully be taken or if the
Trustee determines that such action would be unjustly prejudicial to the holders
not taking part in such direction or would involve the Trustee in personal
liability. (Section 4.07) The Indenture requires the annual filing by the
Company with the Trustee of a certificate as to the absence of certain defaults
under the Indenture. (Section 3.07)
 
MODIFICATION OF THE INDENTURE
 
     The Indenture contains provisions permitting the Company and the Trustee to
modify the Indenture or any supplemental indenture without the consent of the
holders of Securities for certain purposes, provided that no such modification
shall adversely affect the interest of the holders of the Securities in any
material respect. (Section 8.01) The Indenture also contains provisions
permitting the Company and the Trustee, with the consent of the holders of not
less than 66 2/3 percent in principal amount of the Securities at the time
outstanding affected thereby (voting as a class), to modify the Indenture or any
supplemental indenture or the rights of the holders of the Securities; provided
that no such modification shall (i) extend the final maturity of any Security,
or reduce the rate or extend the time of payment of interest thereon, or reduce
the principal amount thereof or any premium thereon, or reduce any amount
payable on redemption thereof, or make the principal of or any interest or
premium on the Securities payable in any coin or currency other than that
provided in the Securities, or impair or affect the right of any holder of a
Security to institute suit for the payment thereof or the right of repayment, if
any, at the option of the holder, without the consent of the holder of each
Security so affected, or reduce the amount of the principal of an Original Issue
Discount Security that would be due and payable upon an acceleration of maturity
thereof or the amount thereof provable in bankruptcy, or (ii) reduce the
aforesaid percentage of Securities the consent of the holders of which is
required for any such modification without the consent of the holders of each
Security affected. (Section 8.02)

ways: (i) directly to purchasers, (ii) through agents, (iii) through
underwriters and (iv) through dealers.
 
     Offers to purchase Securities may be solicited directly by the Company or
by agents designated by the Company from time to time. Any such agent, who may

are set forth in the Prospectus Supplement, which will be used by the
underwriters to make resales of the Securities in respect of which this
Prospectus is delivered to the public.
 
     If a dealer is utilized in the sale of the Securities in respect of which
this Prospectus is delivered, the Company will sell such Securities to the
dealer, as principal. The dealer may then resell such Securities to the public
at varying prices to be determined by such dealer at the time of resale.
 
     Agents, underwriters and dealers may be entitled under the relevant
agreements to indemnification by the Company against certain liabilities,
including liabilities under the Securities Act of 1933.

agents and underwriters to solicit offers by certain institutions to purchase
Securities from the Company at the public offering price set forth in the
Prospectus Supplement pursuant to Delayed Delivery Contracts ("Contracts")
providing for payment and delivery on the date stated in the Prospectus
Supplement. Each Contract will be for an amount not less than, and unless the

stated in the Prospectus Supplement. Institutions with whom Contracts, when
authorized, may be made include commercial and savings banks, insurance
companies, pension funds, investment companies, educational and charitable
institutions and other institutions but shall in all cases be subject to the
approval of the Company. Contracts will not be subject to any conditions except

jurisdiction in the United States to which such institution is subject. A
commission indicated in the Prospectus Supplement will be paid to underwriters
and agents soliciting purchases of Securities pursuant to Contracts accepted by
the Company.
 
     The place and time of delivery for the Securities in respect of which this
Prospectus is delivered are set forth in the accompanying Prospectus Supplement.

     MascoTech, Inc. and its consolidated subsidiaries manufacture products
principally for the original equipment and aftermarket transportation markets.
Transportation-related products are manufactured utilizing a variety of
metalworking and other process technologies. Although published industry
statistics are generally not available, the Company believes that it is a
leading independent producer of many of the industrial component parts that it
produces using cold, warm or hot forming processes. In addition to its
manufacturing activities, the Company provides design and engineering services
primarily for the automotive, heavy truck and aerospace industries. The Company
also manufactures architectural and other specialty industrial products.
 
     The Company's executive offices are located at 21001 Van Born Road, Taylor,
Michigan 48180, and the telephone number is (313) 274-7405. Except as the

                                USE OF PROCEEDS
 
     The Company expects to apply substantially all of the net proceeds from
sales of Subordinated Securities, Preferred Stock, Depositary Shares
representing Preferred Stock or Common Stock by the Company to its general funds
to be used for general corporate purposes, including working capital, repayment
of debt and expenditures for development of activities in which it is now
engaged or investment in and development of activities in which it is not
currently engaged. In this regard, the Company maintains an active acquisition
effort and is frequently engaged in discussions with respect to acquisition
opportunities. Proceeds from sales of Subordinated Securities, Preferred Stock,
Depositary Shares representing Preferred Stock or Common Stock by the Company
could be applied directly or indirectly to such acquisitions. Funds not required
immediately for any of the foregoing purposes may be invested in marketable
securities. The Company intends to use the proceeds from the offering described
in the Prospectus Supplement as set forth in the Prospectus Supplement under the
caption "Use of Proceeds".
 
                     DESCRIPTION OF SUBORDINATED SECURITIES
 
     The Subordinated Securities will be issued under an Indenture dated as of
November 1, 1986 between the Company and The First National Bank of Chicago (as
successor to Morgan Guaranty Trust Company of New York), as Trustee, as amended
by a Supplemental Indenture dated August 5, 1994 (the Indenture as amended by
the Supplemental Indenture is hereinafter referred to as the "Indenture"). The
following statements are subject to the detailed provisions of the Indenture, a
copy of which is filed as an exhibit to the registration statement covering the
Subordinated Securities. Whenever references are made to particular provisions
of the Indenture, such provisions are incorporated by reference as part of the
statements made and such statements are qualified in their entirety by such
references. Certain defined terms are capitalized. References in italics are to
the Indenture. As used in the Indenture, the term "Company" means MascoTech,
Inc. without reference to its consolidated subsidiaries.
 
GENERAL
 
     The Indenture does not limit the amount of Subordinated Securities which
may be issued thereunder. The Prospectus Supplement sets forth the following
terms, where applicable, of the Subordinated Securities in respect of which this
Prospectus is delivered: (1) the title of such Subordinated Securities; (2) any
limit upon the aggregate principal amount of such Subordinated Securities; (3)
the date or dates on which the principal of and premium, if any, on such
Subordinated Securities are payable; (4) the rate or rates at which such
Subordinated Securities shall bear interest or the method by which such interest
may be determined, the date or dates from which such interest shall accrue, the
interest payment dates on which such interest shall be payable and the record
dates for the determination of holders to whom interest is payable; (5) the
place or places where the principal of, and premium, if any, and interest on
such Subordinated Securities shall be payable; (6) the price or prices at which,
the period or periods within which and the terms and conditions upon which such
Subordinated Securities may be redeemed, in whole or in part, at the option of
the Company, pursuant to any sinking fund or otherwise; (7) the obligation, if
any, of the Company to redeem, purchase or repay such Subordinated Securities
pursuant to any sinking fund or analogous provisions or at the option of a
 
                                        3
<PAGE>   15
 
holder thereof and the price or prices at which, the period or periods within
which and the terms and conditions upon which, such Subordinated Securities
shall be redeemed, purchased or repaid, in whole or in part, pursuant to such
obligation; (8) the right, if any, of the Company to discharge or limit the
Indenture with respect to such Subordinated Securities prior to maturity; (9)
any additional Events of Default; (10) any trustees, authenticating or paying
agents, transfer agents or registrars with respect to such Subordinated
Securities; (11) the applicable initial conversion price if such Subordinated
Securities are convertible into Common Stock of the Company and the dates on
which, subsequent to which or until which such Subordinated Securities are
convertible; and (12) such other terms of such Subordinated Securities as are
not inconsistent with the provisions of the Indenture. (Section 2.03)
 
     The Subordinated Securities offered hereby will be issued only in fully
registered form without coupons and, unless otherwise specified in the
Prospectus Supplement, in denominations of $1,000 and any multiple thereof. No
service charge will be made for any transfer or exchange of the Subordinated
Securities, but the Company or the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. (Sections 2.05 and 2.07) Principal, premium, if any, and interest
will be payable and the Subordinated Securities offered hereby will be
transferable, and the Subordinated Securities which are convertible will be
convertible, at the corporate trust office or agency of the Trustee in New York,
New York, provided that payment of interest may be made at the option of the
Company by check mailed to the address of the person entitled thereto as it
appears on the registry books of the Company. (Sections 5.01 and 5.02)
 
     Except as may be set forth in the Prospectus Supplement, the Indenture does
not contain any covenants or provisions which afford holders of Subordinated
Securities protection in the event of a highly leveraged transaction.
 
SUBORDINATION OF SUBORDINATED SECURITIES
 
     The payment of the principal of, and premium, if any, and interest on the
Subordinated Securities is subordinated in right of payment, to the extent set
forth in the Indenture, to the prior payment in full of the principal of, and
premium, if any, and interest on all Senior Indebtedness (as hereinafter
defined). Until such prior payment in full, no payment on account of principal,
premium, if any, sinking funds, if any, or interest may be made on a series of
Subordinated Securities if there shall exist a default in the payment of the
principal, premium, if any, sinking funds, if any, or interest with respect to
such senior indebtedness, if such series of Subordinated Securities is declared
due and payable before its expressed maturity because of the occurrence of an
Event of Default (see "Events of Default, Waiver and Notice" below), in the
event of insolvency, bankruptcy, liquidation, reorganization, dissolution or
winding up of the Company, or if there shall exist a default under such Senior
Indebtedness permitting the holders thereof to accelerate the maturity thereof.
(Sections 4.01, 4.02 and 4.03) The term Senior Indebtedness shall mean (a) all
indebtedness of the Company for money borrowed or incurred in connection with
the acquisition of property, whether outstanding on the date of execution of the
Indenture or thereafter created, assumed or incurred, except such indebtedness
as is by its terms expressly stated to be not superior in right of payment to
the Subordinated Securities or to rank pari passu with the Subordinated
Securities and (b) any deferrals, renewals or extensions of any such Senior
Indebtedness or debentures, notes or other evidences of indebtedness issued in
exchange for such Senior Indebtedness. (Section 1.01) The Indenture does not
limit the incurrence of Senior Indebtedness. By reason of such subordination, in
the event of insolvency, creditors of the Company (including holders of
Subordinated Securities) who are not holders of Senior Indebtedness may recover
less, ratably, than holders of Senior Indebtedness.
 
CONVERSION RIGHTS
 
     Subordinated Securities designated as convertible ("Convertible
Subordinated Securities") by the related Prospectus Supplement will be
convertible into Common Stock of the Company at the time specified in the
Prospectus Supplement (unless a Convertible Subordinated Security shall have
been called for redemption in which case to and including but not after the
business day preceding the date fixed for redemption) initially at the
conversion price set forth on the cover page of the Prospectus Supplement,
adjusted as set forth below. If any Convertible Subordinated Security not called
for redemption is converted
 
                                        4
<PAGE>   16
 
between a record date for the payment of interest and the next succeeding
interest payment date, such Convertible Subordinated Security when delivered for
conversion must be accompanied by funds equal to the interest payable to the
registered holder on such interest payment date on the principal amount so
converted. No other adjustments will be made upon conversion for accrued
interest or dividends. (Sections 3.01 and 3.02)
 
     The conversion price is subject to adjustment in certain events, including
(a) the issuance of shares of capital stock of the Company as a dividend or a
distribution with respect to its Common Stock, (b) subdivisions, combinations
and reclassifications of Common Stock, (c) the issuance to all holders of Common
Stock of rights or warrants entitling them (for a period not exceeding 45 days)
to subscribe for shares of Common Stock at less than the current market price
(as defined in the Indenture), and (d) the distribution to all holders of Common
Stock of evidences of indebtedness of the Company, assets (other than cash
dividends) or subscription rights or warrants (other than those referred to
above). No adjustment in the conversion price will be required unless such
adjustment would require a change of at least 1% in the price then in effect;
provided, however, that any adjustment that would otherwise be required to be
made shall be carried forward and taken into account in any subsequent
adjustment. Except in these cases, the conversion price will not be adjusted for
the issuance of Common Stock. (Section 3.05)
 
     In the event of any consolidation or merger to which the Company is a
party, other than a consolidation or a merger in which the Company is the
continuing corporation and which does not result in any reclassification of, or
change (other than a change in par value or from par value to no par value or
from no par value to par value, or as a result of a subdivision or combination)
in, outstanding shares of Common Stock, or in the event of any sale or
conveyance to another corporation of the assets of the Company as an entirety or
substantially as an entirety, then the holders of Convertible Subordinated
Securities then outstanding shall have the right to convert the Convertible
Subordinated Securities into the kind and amount of shares of stock and other
securities and property (including cash) receivable upon such consolidation,
merger, sale or conveyance by a holder of the number of shares of Common Stock
issuable upon conversion of such Convertible Subordinated Securities immediately
prior to such consolidation, merger, sale or conveyance. (Section 3.06)
 
     Conversion of Convertible Subordinated Securities may be effected by
delivering them to the office or agency of the Company maintained for such
purpose in New York City and in such other places as the Company may determine
from time to time. (Sections 3.02 and 5.02) Fractional shares of Common Stock of
the Company will not be delivered upon conversion, but a cash adjustment in
respect of any such fractional share will be paid. (Section 3.03)
 
     The Company has agreed to reserve out of its authorized but unissued Common
Stock the full number of shares of Common Stock from time to time deliverable
upon the conversion of Convertible Subordinated Securities. (Section 3.09)
 
     In the event of a taxable distribution to holders of Common Stock which
results in an adjustment of the conversion price, the holders of the Convertible
Subordinated Securities may, in certain circumstances, be deemed to have
received a distribution subject to Federal income tax as a dividend. In
addition, the failure to adjust fully the conversion price of the Convertible
Subordinated Securities to reflect distributions to holders of Common Stock may
result in a taxable dividend to the holders of Common Stock.
 
DEFEASANCE
 
     If permitted by the terms of any series of Subordinated Securities, the
Company may terminate certain of its obligations under the Indenture with
respect to such series, including its obligations to comply with the restrictive
covenants described herein, on the terms and subject to the conditions contained
in the Indenture, by depositing in trust with the Trustee money or obligations
of, or guaranteed by, the United States sufficient to pay the principal of,
premium, if any, and interest, if any, on the Subordinated Securities of such
series to maturity (or earlier redemption). (Section 13.01) The Prospectus
Supplement sets forth the defeasance rights, if any, of the Company provided by
the terms of the Subordinated Securities in respect of which this Prospectus is
delivered.

EVENTS OF DEFAULT, WAIVER AND NOTICE
 
     As to each series of Subordinated Securities, an Event of Default is
defined in the Indenture as being: default for 30 days in payment of interest on
the Subordinated Securities of that series; default in payment of principal or
premium, if any, on the Subordinated Securities of that series when due either
at maturity, upon redemption, by declaration or otherwise; default by the
Company in the performance of any other of the covenants included in the
Indenture (other than a covenant included in the Indenture solely for the
benefit of a series of Subordinated Securities other than that series) which
shall not have been remedied for a period of 90 days after notice; and certain
events of bankruptcy, insolvency and reorganization of the Company. (Section
7.01) The Indenture provides that the Trustee thereunder may withhold notice to
the holders of the Subordinated Securities of any default (except in payment of
principal of or premium, if any, or interest on the Subordinated Securities) if
such Trustee considers it in the interest of the holders of the Subordinated
Securities to do so. (Section 7.08)
 
     The Indenture provides that (i) if an Event of Default due to the default
in the payment of principal, interest or premium on any series of Subordinated
Securities or due to the default in the performance, or breach, of any covenant
set forth exclusively in the terms of such series of Subordinated Securities
established as contemplated in the Indenture shall have occurred and be
continuing, either the Trustee or the holders of 25 percent in principal amount
of the Subordinated Securities of such series then outstanding under the
Indenture may declare the principal of all Subordinated Securities of such
series and interest accrued thereon to be due and payable immediately and (ii)
if an Event of Default resulting from default in the performance of any other of
the covenants or agreements in the Indenture and certain events of bankruptcy,
insolvency and reorganization of the Company shall have occurred and be
continuing, either the Trustee or the holders of 25 percent in principal amount
of all Subordinated Securities then outstanding under the Indenture (treated as
one class) may declare the principal of all Subordinated Securities issued under
the Indenture and interest accrued thereon to be due and payable immediately,
but upon certain conditions such declarations may be annulled and past defaults
may be waived (except a continuing default in payment of principal of or
interest or premium on the Subordinated Securities) by the holders of a majority
in principal amount of the Subordinated Securities of such series (or of all
series, as the case may be) then outstanding under the Indenture. (Section 7.01)
 
     The holders of a majority in principal amount of the Subordinated
Securities of any or all series at the time outstanding shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee under the Indenture. Notwithstanding the foregoing,
such Trustee shall have the right to decline to follow any such direction if the
Trustee is advised by counsel that the action so directed may not lawfully be
taken or if the Trustee determines that such action would be unjustly
prejudicial to the holders not taking part in such direction or would involve
the Trustee in personal liability. (Section 7.07) The Indenture requires the
annual filing by the Company with the Trustee of a certificate as to the absence
of certain defaults under the Indenture. (Section 5.05)
 
MODIFICATION OF THE INDENTURE
 
     The Indenture contains provisions permitting the Company and the Trustee to
modify the Indenture or any supplemental indenture without the consent of the
holders of Subordinated Securities for certain purposes, provided that no such
modification shall adversely affect the interest of the holders of the
Subordinated Securities in any material respect. (Section 8.01) The Indenture
also contains provisions permitting the Company and the Trustee thereunder, with
the consent of the holders of not less than 66 2/3 percent in principal amount
of the Subordinated Securities at the time outstanding affected thereby (voting
as a class), to modify the Indenture or any supplemental indenture or the rights
of the holders of the Subordinated Securities; provided that no such
modification shall (i) extend the final maturity of any Subordinated Security,
or reduce the rate or extend the time of payment of interest thereon, or reduce
the principal amount thereof or any premium thereon, or reduce any amount
payable on redemption thereof, or make the principal of, or interest or premium
on, the Subordinated Securities payable in any coin or currency other than that
provided in the Subordinated Securities, or impair the right to convert
Convertible Subordinated Securities into Common Stock in accordance with the
Indenture, or impair or affect the right of any holder of a Subordinated
Security
 
                                        6
<PAGE>   18
 
to institute suit for the payment thereof or the right of repayment, if any, at
the option of the holder, or modify any of the provisions relating to
subordination of the Subordinated Securities in a manner adverse to the holders
thereof without the consent of the holder of each Subordinated Security so
affected, or (ii) reduce the aforesaid percentage of Subordinated Securities the
consent of the holders of which is required for any such modification without
the consent of the holders of each Subordinated Security affected. (Section
11.02)
 
SUCCESSOR CORPORATION
 
     Under the terms of the Indenture, the Company may consolidate or merge or
sell all or substantially all of its assets if (a) the Company is the continuing
corporation or if the Company is not the continuing corporation, such continuing
corporation is organized and existing under the laws of the United States of
America or any state or territory thereof or the District of Columbia and
assumes by supplemental indenture the due and punctual payment of the principal
of, and the premium, if any, and interest on the Subordinated Securities and the
due and punctual performance and observance of all of the covenants and
conditions of the Indenture to be performed by the Company and (b) the Company
or such continuing corporation is not in default in the performance of any such
covenant or condition immediately after such merger, consolidation or sale of
assets. (Article Twelve)
 
CONCERNING THE TRUSTEE

services for the Company from time to time in the normal course of business.
 
                         DESCRIPTION OF PREFERRED STOCK
 
     The Company is authorized to issue 25 million shares of Preferred Stock.
The Board of Directors is authorized to issue Preferred Stock in one or more
series and to determine the voting powers (if any), designation, preferences and
relative rights and qualifications, limitations or restrictions thereof, for
each series of Preferred Stock that may be issued and to fix the number of
shares of each series without further action by the stockholders, unless action
is required by applicable laws or regulations or by the terms of outstanding
Preferred Stock. The Prospectus Supplement sets forth the particular
designation, preferences and rights of any series of Preferred Stock in respect
of which this Prospectus is delivered.
 
     The rights of holders of the Preferred Stock offered hereby will be subject
to, and may be adversely affected by, the rights of holders of any Preferred
Stock that may be issued in the future. Shares of Preferred Stock issued by the
Company may have the effect, under certain circumstances, alone or in
combination with certain other provisions of the Company's Restated Certificate
of Incorporation, of rendering more difficult or discouraging an acquisition of
the Company deemed undesirable by the Board of Directors.
 
                              PLAN OF DISTRIBUTION
 
     The Company may sell the Subordinated Securities, Preferred Stock,
Depositary Shares representing Preferred Stock and Common Stock being offered
hereby in any of four ways: (i) directly to purchasers, (ii) through agents,
(iii) through underwriters and (iv) through dealers.
 
     Offers to purchase Subordinated Securities, Preferred Stock, Depositary
Shares representing Preferred Stock or Common Stock may be solicited directly by
the Company or by agents designated by the Company from time to time. Any such
agent, who may be deemed to be an underwriter as that term is defined in the
Securities Act of 1933, involved in the offer or sale of the Subordinated
Securities, Preferred Stock, Depositary Shares representing Preferred Stock or
Common Stock in respect of which this Prospectus is delivered is named, and any
commissions payable by the Company to such agent are set forth, in the
Prospectus Supplement. Unless otherwise indicated in the Prospectus Supplement,
any such agent will be acting on a best efforts basis for the period of its
appointment (ordinarily five business days or less). Agents may be customers of,
engage in transactions with or perform services for, the Company in the ordinary
course of business.
 
                                        7
<PAGE>   19
 
     If an underwriter or underwriters are utilized in the sale, the Company
will execute an underwriting agreement with such underwriters at the time of
sale to them, and the names of the underwriters and the terms of the transaction
are set forth in the Prospectus Supplement, which will be used by the
underwriters to make resales of the Subordinated Securities, Preferred Stock,
Depositary Shares representing Preferred Stock or Common Stock in respect of
which this Prospectus is delivered to the public.
 
     If a dealer is utilized in the sale of the Subordinated Securities,
Preferred Stock, Depositary Shares representing Preferred Stock or Common Stock
in respect of which this Prospectus is delivered, the Company will sell such
Subordinated Securities, Preferred Stock, Depositary Shares representing
Preferred Stock or Common Stock to the dealer, as principal. The dealer may then
resell such Subordinated Securities, Preferred Stock, Depositary Shares
representing Preferred Stock or Common Stock to the public at varying prices to
be determined by such dealer at the time of resale.
 
     Agents, underwriters and dealers may be entitled under the relevant
agreements to indemnification by the Company against certain liabilities,
including liabilities under the Securities Act of 1933.
 
     If so indicated in the Prospectus Supplement, the Company will authorize
agents and underwriters to solicit offers by certain institutions to purchase
Subordinated Securities from the Company at the public offering price set forth
in the Prospectus Supplement pursuant to Delayed Delivery Contracts
("Contracts") providing for payment and delivery on the date stated in the
Prospectus Supplement. Each Contract will be for an amount not less than, and
unless the Company otherwise agrees the aggregate principal amount of
Subordinated Securities sold pursuant to Contracts shall be not less nor more
than, the respective amounts stated in the Prospectus Supplement. Institutions
with whom Contracts, when authorized, may be made include commercial and savings
banks, insurance companies, pension funds, investment companies, educational and
charitable institutions and other institutions but shall in all cases be subject
to the approval of the Company. Contracts will not be subject to any conditions
except that the purchase by an institution of the Subordinated Securities
covered by its Contract shall not at the time of delivery be prohibited under
the laws of any jurisdiction in the United States to which such institution is
subject. A commission indicated in the Prospectus Supplement will be paid to
underwriters and agents soliciting purchases of Subordinated Securities pursuant
to Contracts accepted by the Company.
 
     The place and time of delivery for the Subordinated Securities, Preferred
Stock, Depositary Shares representing Preferred Stock or Common Stock in respect
of which this Prospectus is delivered are set forth in the Prospectus
Supplement.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the General Corporation Law of Delaware empowers the Company
to indemnify, subject to the standards therein prescribed, any person in
connection with any action, suit or proceeding brought or threatened by reason
of the fact that such person is or was a Director, officer, employee or agent of
the Company or is or was serving as such with respect to another corporation or
other entity at the request of the Company. Article 14 of the Company's Restated
Certificate of Incorporation provides that each person who was or is made a
party to (or is threatened to be made a party to) or is otherwise involved in
any action, suit or proceeding by reason of the fact that such person is or was
a Director, officer or employee of the Company shall be indemnified and held
harmless by the Company to the fullest extent authorized by the General
Corporation Law of Delaware against all expense, liability and loss (including
without limitation attorneys' fees, judgments, fines and amounts paid in
settlement) reasonably incurred by such person in connection therewith. The
rights conferred by Article 14 are contractual rights and include the right to
be paid by the Company the expenses incurred in defending such action, suit or
proceeding in advance of the final disposition thereof.

that a director of the Company will not be personally liable to the Company or
its stockholders for monetary damages for breach of fiduciary duty as a director
except for liability (a) for any breach of the director's duty of loyalty to the
Company or its stockholders, (b) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (c) under
Section 174 of the Delaware General Corporation Law, or (d) for transactions
from which the director derived improper personal benefit.
 
     The Company's Directors and officers are covered by insurance policies
indemnifying them against certain civil liabilities, including liabilities under
the Federal securities laws (other than liability under Section 16(b) of the
1934 Act), which might be incurred by them in such capacity.

ITEM 17. UNDERTAKINGS.
 
     1. The Company hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the Prospectus any facts or events arising after
        the effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statement; and
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the Registration Statement
        or any material change to such information in the Registration
        Statement;
 
     provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed by the Company pursuant
     to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that
     are incorporated by reference in the Registration Statement.
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new Registration Statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     2. The Company hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the Company's annual
report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act
of 1934 that is incorporated by reference in the Registration Statement shall be
deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     3. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to Directors, officers and controlling persons of
the Company pursuant to the provisions referred to in Item 15 above, the Company
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is
therefore unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Company of expenses incurred or
paid by a Director, officer, or controlling person of the Company in the
successful defense of any action, suit or proceeding) is asserted by such
Director, officer or controlling person in connection with the securities being
registered, the Company will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in that Act and will be governed by the final
adjudication of such issue.

of the  Board of Directors, President, any Vice President, its Treasurer or an
Assistant Treasurer or its Secretary or an Assistant Secretary without any
further action by the 

                                     13
<PAGE>
<PAGE>

Company hereunder.  To the extent authorized in a resolution of the Board of
Directors and set forth in an Officers' Certificate or established in one or
more supplemental indentures, such written order of the Company may be
electronically transmitted and may provide instructions as to registration of
holders, principal amounts, rates of interest, maturity dates and other matters
contemplated by such resolution of the Board of Directors and Officers'
Certificate or supplemental indenture.  In authenticating such Securities, and
accepting the additional responsibilities under this Indenture in relation to
such Securities, the Trustee shall be entitled to receive (in the case of
subparagraphs 2, 3 and 4 below only at or before the time of the first request

        (1)   a copy of any resolution or resolutions of the Board of Directors
  relating thereto and, if applicable, an appropriate record of any action
  taken pursuant to such resolution, in each case certified by the Secretary or
  an Assistant Secretary of the Company;

        (2)   an executed supplemental indenture, if any;

        (3)   an Officers' Certificate prepared in accordance with Section
  12.05 setting forth the form and terms of the Securities as required pursuant
  to Sections 2.01 and 2.03, respectively; and

        (4)   an Opinion of Counsel prepared in accordance with Section 12.05
  which shall also state

              (a) that the form of such Securities has been established by or
        pursuant to a resolution of the Board of Directors or by a supplemental
        indenture as permitted by Section 2.01 in conformity with the
        provisions of this Indenture;

              (b)   that the terms of such Securities have been established by
        or pursuant to a resolution of the Board of Directors or by a
        supplemental indenture as permitted by Section 2.03 in conformity with
        the provisions of this Indenture;

              (c)   that such Securities, when authenticated and delivered by
        the Trustee and issued by the Company in the manner and subject to any
        conditions specified in such Opinion of Counsel, 

                                     14
<PAGE>
<PAGE>

        will constitute valid and legally binding obligations of the Company;

              (d)   that all laws and requirements in respect of the execution
        and delivery by the Company of the Securities have been complied with
        and that authentication and delivery of the Securities by the Trustee
        will not violate the terms of this Indenture; and

              (e)   such other matters as the Trustee may reasonably request.

        The Trustee shall have the right to decline to authenticate and deliver
any Securities under this Section if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken or if the Trustee in good
faith by its board of directors or trustees, executive committee, or a trust
committee of directors or trustees and/or vice presidents shall determine that
such action would expose the Trustee to personal liability to existing holders.

        If the Company shall establish pursuant to Section 2.03 that the
Securities of a series are to be issued in the form of one or more Global
Securities, then the Company shall execute and the Trustee shall, in accordance
with this Section and the written order of the Company with respect to such
series, authenticate and deliver one or more Global Securities that (i) shall
represent and shall be denominated in an amount equal to the aggregate principal
amount of all of the Securities of such series issued and not yet cancelled,
(ii) shall be registered in the name of the Depositary for such Global Security
or Securities or the nominee of such Depositary, (iii) shall be delivered by the
Trustee to such Depositary or pursuant to such Depositary's instructions and
(iv) shall bear a legend substantially to the following effect:  "Unless and
until it is exchanged in whole or in part for Securities in definitive
registered form, this Security may not be transferred except as a whole by the
Depositary to the nominee of the Depositary or by a nominee of the Depositary to
the Depositary or another nominee of the Depositary or by the Depositary or any
such nominee to a successor Depositary or a nominee of such successor
Depositary."

        Each Depositary designated pursuant to Section 2.03 must, at the time
of its designation and at all times while it serves as Depositary, be a clearing
agency registered under the Securities Exchange Act of 1934 and any other
applicable statute or regulation.

        SECTION 2.05.  Date and Denomination of Securities.  The Securities
shall be issuable as registered Securities without coupons and in such
denominations as shall be specified as contemplated by Section 2.03.  In the
absence of any such specification with respect to the Securities of any series,
the Securities of such series shall be issuable in denominations of $1,000 and
any multiple thereof.  The Securities shall be numbered, lettered, or otherwise
distinguished in such manner or in accordance with such plans as the officers of
the Company executing the same may determine with the approval of the Trustee as
evidenced by the execution and authentication thereof.

        Every Security shall be dated the date of its authentication, shall
bear interest, if any, from such date and shall be payable on such dates, in
each case, as contemplated by Section 2.03.

        The person in whose name any Security of any series is registered at
the close of business on any record date (as hereinafter defined) with respect
to any interest payment date shall be entitled to receive the interest, if any,
payable on such interest payment date notwithstanding the cancellation of such
Security upon any transfer or exchange subsequent to the record date and prior
to such interest payment date, except that interest shall not be payable to such
person with respect to a Security called for redemption on a redemption date
between a record date and the interest payment date for such interest; provided,
however, that if and to the extent the Company shall default in the payment of
the interest due on such interest payment date, such defaulted interest shall be
paid to the persons in whose names outstanding Securities are registered on a
subsequent record date established by notice given by mail by or on behalf of
the Company to the holders of Securities and the Trustee not less than 15 days
preceding such subsequent record date, such subsequent record date to be not
less than ten days preceding the date of payment of such defaulted interest. 
The term "record date" as used in this Section with respect to any interest
payment date shall mean if such interest payment date is the first day of a
calendar month, the fifteenth day of the next preceding calendar month and shall
mean, if such interest payment date is the fifteenth day of a calendar month,
the first day of such calendar month, whether or not such record date is a
business day.

        SECTION 2.06.  Execution of Securities.  The Securities shall be signed
in the name and on behalf of the Company by the manual or facsimile signature of
its Chairman 

                                     16
<PAGE>
<PAGE>

of the Board or its President and imprinted with a manual or facsimile of its
corporate seal and attested by the manual or facsimile signature of its
Secretary or an Assistant Secretary.  Each such signature upon the Securities
may be in the form of a facsimile signature of any such officer and may be
imprinted or otherwise reproduced on the Securities and for that purpose the
Company may adopt and use the facsimile signature of any person who has been or
is such officer, and in case any such officer of the Company signing any of the
Securities shall cease to be such officer before the Securities so signed shall
have been authenticated and delivered by the Trustee, or disposed of by the
Company, such Securities nevertheless may be authenticated and delivered or
disposed of as though such person had not ceased to be such officer of the
Company.  Only such Securities as shall bear thereon a certificate of
authentication substantially in the form hereinbefore recited, executed by the
Trustee or the Authenticating Agent, shall be entitled to the benefits of this
Indenture or be valid or obligatory for any purpose.  Such certificate by the
Trustee or the Authenticating Agent upon any Security executed by the Company
shall be conclusive evidence that the Security so authenticated has been duly
authenticated and delivered hereunder and that the holder is entitled to the
benefits of this Indenture.

        SECTION 2.07.  Exchange and Registration of Transfer of Securities. 
Securities of any series (except Global Securities, other than as set forth in
this Section 2.07) may be exchanged for a like aggregate principal amount of
Securities of the same series of other authorized denominations.  Securities to
be exchanged may be surrendered at the principal office of the Trustee or at any
office or agency to be maintained by the Company for such purpose as provided in
Section 3.02, and the Company or the Trustee shall execute and register and the
Trustee or the Authenticating Agent shall authenticate and deliver in exchange
therefor the Security or Securities which the Securityholder making the exchange
shall be entitled to receive.  Upon due presentment for registration of transfer
of any Security of any series at the principal office of the Trustee or at any
office or agency of the Company maintained for such purpose as provided in
Section 3.02, the Company or the Trustee shall execute and register and the
Trustee or the Authenticating Agent shall authenticate and deliver in the name
of the transferee or transferees a new Security or Securities of the same series
for a like aggregate principal amount.  Registration or registration of transfer
of any Security by the Trustee or by any agent of the Company appointed pursuant
to Section 3.02, and delivery of such 

                                     17
<PAGE>
<PAGE>

Security, shall be deemed to complete the registration or registration of
transfer of such Security.

        The Company or the Trustee shall keep, at the principal office of the
Trustee, a register for each series of Securities issued hereunder in which,
subject to such reasonable regulations as it may prescribe, the Company or the
Trustee shall register all Securities and shall register the transfer of all
Securities as in this Article Two provided.  Such register shall be in written
form or in any other form capable of being converted into written form within a
reasonable time.

        All Securities presented for registration of transfer or for exchange
or payment shall (if so required by the Company or the Trustee or the
Authenticating Agent) be duly endorsed by, or be accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company and
the Trustee or the Authenticating Agent duly executed by, the holder or his
attorney duly authorized in writing.

        No service charge shall be made for any exchange or registration of
transfer of Securities, but the Company or the Trustee may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection therewith.

        The Company or the Trustee shall not be required (i) to issue, register
the transfer of or exchange Securities of any particular series and tenor during
a period beginning at the opening of business 15 days before the day of the
mailing of a notice of redemption of Securities of like tenor and of the series
of which such Security is a part, selected for redemption under Section 13.02
and ending at the close of business on the day of such mailing, or (ii) to
register the transfer of or exchange any Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed
in part.

        Notwithstanding any other provisions of this Section 2.07, unless and
until it is exchanged in whole or in part for Securities in definitive
registered form, a Global Security representing all or a portion of the
Securities of a series may not be transferred except as a whole by the
Depositary for such series to a nominee of such Depositary or by a nominee of
such Depositary to such Depositary or another nominee of such Depositary or by
such Depositary or any such nominee to a successor Depositary for such series or
a nominee of such successor Depositary.

                                     18

        If at any time the Depositary for any Securities of a series
represented by one or more Global Securities notifies the Company that it is
unwilling or unable to continue as Depositary for such Securities or if at any
time the Depositary for such Securities shall no longer be eligible under
Section 2.03, the Company shall appoint a successor Depositary with respect to
such Securities.  If a successor Depositary for such Securities is not appointed
by the Company within 90 days after the Company receives such notice or becomes
aware of such ineligibility, the Company's election pursuant to Section 2.03
that such Securities be represented by one or more Global Securities shall no
longer be effective and the Company will execute, and the Trustee, upon receipt
of a written order of the Company for the authentication and delivery of
definitive Securities of such series, will authenticate and deliver, Securities
of such series in definitive registered form without coupons, in any authorized
denominations, in an aggregate principal amount equal to the principal amount of
the Global Security or Securities representing such Securities in exchange for
such Global Security or Securities.

        The Company may at any time and in its sole discretion determine that
the Securities of any series issued in the form of one or more Global Securities
shall no longer be represented by a Global Security or Securities.  In such
event the Company will execute, and the Trustee, upon receipt of a written order
of the Company for the authentication and delivery of the definitive Securities
of such series, will authenticate and deliver, Securities of such series in
definitive registered form without coupons, in any authorized denominations, in
an aggregate principal amount equal to the principal amount of the Global
Security or Securities representing such Securities, in exchange for such Global
Security or Securities.

        If specified by the Company pursuant to Section 2.03 with respect to
Securities represented by a Global Security, the Depositary for such Global
Security may surrender such Global Security in exchange in whole or in part for
Securities of the same series in definitive registered form on such terms as are
acceptable to the Company and such Depositary.  Thereupon, the Company shall
execute, and the Trustee shall authenticate and deliver, without service charge,

        (i)   to the Person specified by such Depositary a new Security or
  Securities of the same series, of any authorized denominations as requested
  by such Person, in an aggregate principal amount equal to and in 

                                     19
<PAGE>
<PAGE>

  exchange for such Person's beneficial interest in the Global Security; and

        (ii)  to such Depositary a new Global Security in a denomination equal
  to the difference, if any, between the principal amount of the surrendered
  Global Security and the aggregate principal amount of Securities
  authenticated and delivered pursuant to clause (i) above.

        SECTION 2.08.  Mutilated, Destroyed, Lost or Stolen Securities.  In
case any temporary or definitive Security shall become mutilated or be
destroyed, lost or stolen, the Company in the case of a mutilated Security
shall, and in the case of a lost, stolen or destroyed Security may in its
discretion, execute, and upon its request the Trustee shall authenticate and
deliver, a new Security of the same series bearing a number not
contemporaneously outstanding, in exchange and substitution for the mutilated
Security, or in lieu of and in substitution for the Security so destroyed, lost
or stolen.  In every case the applicant for a substituted Security shall furnish
to the Company and the Trustee such security or indemnity as may be required by
them to save each of them harmless, and, in every case of destruction, loss or
theft, the applicant shall also furnish to the Company and the Trustee evidence
to their satisfaction of the destruction, loss or theft of such Security and of
the ownership thereof.

        The Trustee may authenticate any such substituted Security and deliver
the same upon the written request or authorization of any officer of the
Company.  Upon the issuance of any substituted Security, the Company may require
the payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation thereto and any other expenses connected
therewith.  In case any Security which has matured or is about to mature or has
been called for redemption in full shall become mutilated or be destroyed, lost
or stolen, the Company may, instead of issuing a substitute Security, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated Security) if the applicant for such payment shall furnish to the
Company and the Trustee such security or indemnity as may be required by them to
save each of them harmless and, in case of destruction, loss or theft, evidence
satisfactory to the Company and to the Trustee of the destruction, loss or theft
of such Security and of the ownership thereof.

        Every substituted Security of any series issued pursuant to the
provisions of this Section 2.08 by virtue of 

                                     20
<PAGE>
<PAGE>

the fact that any such Security is destroyed, lost or stolen shall constitute an
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be found at any time, and shall be entitled to all
the benefits of this Indenture equally and proportionately with any and all
other Securities of the same series duly issued hereunder.  All Securities shall
be held and owned upon the express condition that, to the extent permitted by
applicable law, the foregoing provisions are exclusive with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities and
shall preclude any and all other rights or remedies notwithstanding any law or
statute existing or hereafter enacted to the contrary with respect to the
replacement or payment of negotiable instruments or other securities without
their surrender.

        SECTION 2.09.  Temporary Securities.  Pending the preparation of
definitive Securities of any series the Company may execute and the Trustee
shall authenticate and deliver temporary Securities (printed or lithographed). 
Temporary Securities shall be issuable in any authorized denomination, and
substantially in the form of the definitive Securities but with such omissions,
insertions and variations as may be appropriate for temporary Securities, all as
may be determined by the Company.  Every such temporary Security shall be
executed by the Company and be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with the same effect, as
the definitive Securities.  Without unreasonable delay the Company will execute
and deliver to the Trustee or the Authenticating Agent definitive Securities and
thereupon any or all temporary Securities of such series may be surrendered in
exchange therefor, at the principal office of the Trustee or at any office or
agency maintained by the Company for such purpose as provided in Section 3.02,
and the Trustee or the Authenticating Agent shall authenticate and deliver in
exchange for such temporary Securities a like aggregate principal amount of such
definitive Securities.  Such exchange shall be made by the Company at its own
expense and without any charge therefor except that in case of any such exchange
involving a registration of transfer the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto.  Until so exchanged, the temporary Securities of any series
shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities of the same series authenticated and delivered hereunder.

        SECTION 2.10.  Cancellation of Securities Paid, etc.  All Securities
surrendered for the purpose of payment, redemption, exchange or registration of
transfer or for credit in lieu of retiring Funded Debt pursuant to Section 3.06
shall, if surrendered to the Company or any paying agent, be surrendered to the
Trustee and promptly cancelled by it, or, if surrendered to the Trustee or any
Authenticating Agent, shall be promptly cancelled by it, and no Securities shall
be issued in lieu thereof except as expressly permitted by any of the provisions
of this Indenture.  All Securities cancelled by any Authenticating Agent shall
be delivered to the Trustee.  The Trustee shall destroy cancelled Securities and
shall deliver a certificate of such destruction to the Company.  If the Company
shall acquire any of the Securities, however, such acquisition shall not operate
as a redemption or satisfaction of the indebtedness represented by such
Securities unless and until the same are surrendered to the Trustee for
cancellation.

                               ARTICLE THREE.

                     PARTICULAR COVENANTS OF THE COMPANY
                              AND THE TRUSTEE.

        SECTION 3.01.  Payment of Principal, Premium and Interest.  The Company
covenants and agrees for the benefit of each series of Securities that it will
duly and punctually pay or cause to be paid the principal of and premium, if
any, and any interest on each of the Securities of that series at the place, at
the respective times and in the manner provided in such Securities.  Each
instalment of interest, if any, on the Securities of any series may be paid by
mailing checks for such interest payable to the order of the holders of
Securities entitled thereto as they appear on the registry books of the Company.

        SECTION 3.02.  Offices for Notices and Payments, etc.  So long as any
of the Securities remains outstanding, the Company will maintain in the Borough
of Manhattan, The City of New York, an office or agency where the Securities of
each series may be presented for payment, an office or agency where the
Securities of that series may be presented for registration of transfer and for
exchange as in this Indenture provided and an office or agency where notices and
demands to or upon the Company in respect of the Securities of that series or of
this Indenture may be served.  The Company will give to the Trustee written
notice of the location of any such office or agency and of any change of
location thereof.  Until otherwise designated from time to time by the Company
in a notice to the Trustee, or specified as contemplated by Section 2.03, such
office or agency for 

                                     22
<PAGE>
<PAGE>

all of the above purposes shall be the principal office of the Trustee.  In case
the Company shall fail to maintain any such office or agency in the Borough of
Manhattan, The City of New York, or shall fail to give such notice of the
location or of any change in the location thereof, presentations and demands may
be made and notices may be served at the principal office of the Trustee.

        In addition to such office or agency, the Company  may from time to
time designate one or more offices or agencies outside the Borough of Manhattan,
The City of New York, where the Securities may be presented for registration of
transfer and for exchange in the manner provided in this Indenture, and the
Company may from time to time rescind such designation, as the Company may deem
desirable or expedient; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
such office or agency in the Borough of Manhattan, The City of New York, for the
purposes above mentioned.  The Company will give to the Trustee prompt written
notice of any such designation or rescission thereof.

        SECTION 3.03.  Appointments to Fill Vacancies in Trustee's Office.  The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 5.09, a Trustee, so that there
shall at all times be a Trustee hereunder.

        SECTION 3.04.  Provision as to Paying Agent.  (a) If the Company shall
appoint a paying agent other than the Trustee with respect to the Securities of
any series, it will cause such paying agent to execute and deliver to the
Trustee an instrument in which such agent shall agree with the Trustee, subject
to the provisions of this Section 3.04:

        (1)   that it will hold all sums held by it as such agent for the
  payment of the principal of and premium, if any, or interest, if any, on the
  Securities of such series (whether such sums have been paid to it by the
  Company or by any other obligor on the Securities of such series) in trust
  for the benefit of the holders of the Securities of such series,

        (2)   that it will give the Trustee notice of any failure by the
  Company (or by any other obligor on the Securities of such series) to make
  any payment of the principal of and premium, if any, or interest, if any, on
  the Securities of such series when the same shall be due and payable, and

                                     23
<PAGE>
<PAGE>
        (3)  pay any such sums so held in trust by it to the Trustee upon the
  Trustee's written request at any time during the continuance of the failure
  referred to in clause (2) above.

        (b)   If the Company shall act as its own paying agent, it will, on or
before each due date of the principal of and premium, if any, or interest, if
any, on the Securities of any series, set aside, segregate and hold in trust for
the benefit of the holders of the Securities of such series a sum sufficient to
pay such principal, premium or interest so becoming due and will notify the
Trustee of any failure to take such action and of any failure by the Company (or
by any other obligor under the Securities of such series) to make any payment of
the principal of and premium, if any, or interest, if any, on the Securities of
such series when the same shall become due and payable.

        (c)   Anything in this Section 3.04 to the contrary notwithstanding,
the Company may, at any time, for the purpose of obtaining a satisfaction and
discharge with respect to one or more or all series of Securities hereunder, or
for any other reason, pay or cause to be paid to the Trustee all sums held in
trust for any such series by the Trustee or any paying agent hereunder, as
required by this Section 3.04, such sums to be held by the Trustee upon the
trusts herein contained.

        (d)   Anything in this Section 3.04 to the contrary notwithstanding,
the agreement to hold sums in trust as provided in this Section 3.04 is subject
to Sections 10.03 and 10.04.

        SECTION 3.05.  Limitation on Liens.  (a)  The Company will not, nor
will it permit any Consolidated Subsidiary to, issue, assume or guarantee any
debt for money borrowed or any Funded Debt (hereinafter in this Article Three
referred to as "Debt"), secured by a mortgage, security interest, pledge, lien
or other encumbrance (mortgages, security interests, pledges, liens and other
encumbrances being hereinafter called a "mortgage" or "mortgages") upon any
Principal Property or upon any shares of stock or indebtedness of any
Consolidated Subsidiary which owns or leases a Principal Property (whether such
Principal Property, shares of stock or indebtedness are now owned or hereafter
acquired) without in any such case effectively providing concurrently with the
issuance, assumption or guaranty of any such Debt that the Securities (together
with, if the Company shall so determine, any other indebtedness of or guaranteed
by the Company or such Consolidated Subsidiary ranking equally with the
Securities 

                                     24
<PAGE>
<PAGE>
and then existing or thereafter created) shall be secured equally and ratably
with such Debt; provided, however, that the foregoing restrictions shall not
apply to Debt secured by:

        (i)   mortgages on property, shares of stock or indebtedness of any
  corporation existing at the time such corporation becomes a Consolidated
  Subsidiary;

      (ii)    mortgages on property existing at the time of acquisition of such
  property by the Company or a Consolidated Subsidiary, or mortgages to secure
  the payment of all or any part of the purchase price of such property upon
  the acquisition of such property by the Company or a Consolidated Subsidiary
  or to secure any Debt incurred by the Company or a Consolidated Subsidiary
  prior to, at the time of, or within 120 days after the later of the
  acquisition, the completion of construction (including any improvements on an
  existing property) or the commencement of commercial operation of such
  property, which Debt is incurred for the purpose of financing all or any part
  of the purchase price thereof or construction or improvements thereon;
  provided, however, that in the case of any such acquisition, construction or
  improvement, the mortgage shall not apply to any property theretofore owned
  by the Company or a Consolidated Subsidiary, other than any property on which
  the property so constructed or the improvement is located or to which the
  property so constructed or the improvement is appurtenant;

     (iii)    mortgages securing Debt of a Consolidated Subsidiary owing to the
  Company or to another Consolidated Subsidiary;

      (iv)    mortgages on property of a corporation existing at the time such
  corporation is merged or consolidated with the Company or a Consolidated
  Subsidiary or at the time of a sale, lease or other disposition of the
  properties of a corporation or firm as an entirety or substantially as an
  entirety to the Company or a Consolidated Subsidiary; provided, however, that
  no such mortgage shall extend to any other Principal Property of the Company
  or any Consolidated Subsidiary or to any shares of capital stock or any
  indebtedness of any Consolidated Subsidiary which owns or leases a Principal
  Property;

        (v)   mortgages on property of the Company or a Consolidated Subsidiary
  in favor of the United States of America or any State thereof, or any
  department, 

                                     25
<PAGE>
<PAGE>
  agency or instrumentality or political subdivision of the United States of
  America or any State thereof, or in favor of any other country, or any
  political subdivision thereof, to secure partial, progress, advance or other
  payments pursuant to any contract or statute (including Debt of the pollution
  control or industrial revenue bond type) or to secure any indebtedness
  incurred for the purpose of financing all or any part of the purchase price
  or the cost of construction of the property subject to such mortgages; or

      (vi)    any extension, renewal or replacement (or successive extensions,
  renewals or replacements) in whole or in part of mortgages existing at the
  date of this Indenture, or any mortgage referred to in the foregoing clauses
  (i) through (v), inclusive, provided, however, that the principal amount of
  Debt secured thereby shall not exceed the principal amount of Debt so secured
  at the time of such extension, renewal or replacement, and that such
  extension, renewal or replacement shall be limited to all or a part of the
  property which secured the mortgage so extended, renewed or replaced (plus
  improvements on such property).

        (b)   Notwithstanding the foregoing provisions of this Section 3.05,
the Company may, and may permit any Consolidated Subsidiary to, issue, assume or
guarantee Debt secured by a mortgage not excepted by clauses (i) through (vi) of
paragraph (a) above without equally and ratably securing the Securities,
provided, however, that the aggregate principal amount of all such Debt then
outstanding, plus the aggregate principal amount of the Debt then being issued,
assumed, or guaranteed, and the aggregate amount of the Attributable Debt in
respect of sale and lease-back arrangements, shall not exceed 5% of Consolidated
Net Tangible Assets, determined as of a date not more than 90 days prior
thereto.

        SECTION 3.06.  Limitation on Sale and Leaseback.  the Company will not,
nor will it permit any Consolidated Subsidiary to, enter into any arrangement
with any person providing for the leasing by the Company or any Consolidated
Subsidiary of any Principal Property (whether such Principal Property is now
owned or hereafter acquired) (except for leases for a term of not more than
three years and except for leases between the Company and a Consolidated
Subsidiary or between Consolidated Subsidiaries), which property has been or is
to be sold or transferred by the Company or such Consolidated Subsidiary to such
person, unless (a) the 

                                     26
<PAGE>
<PAGE>

Company or such Subsidiary would be entitled, pursuant to the provisions of
Section 3.05, to issue, assume or guarantee Debt secured by a mortgage upon such
property at least equal in amount to the Attributable Debt in respect of such
arrangement without equally and ratably securing the Securities or (b) the
Company or a Consolidated Subsidiary, within 120 days of the effective date of
any such arrangement, applies an amount equal to the greater of the net proceeds
of the sale of the Principal Property leased pursuant to such arrangement or the
fair market value of the Principal Property so leased at the time of entering
into such arrangement (as determined by the Board of Directors of the Company)
to the retirement (other than any mandatory retirement or by way of payment at
maturity) of Funded Debt of the Company or any Consolidated Subsidiary (other
than Funded Debt owned by the Company or any Consolidated Subsidiary and other
than Funded Debt subordinated in the payment of principal or interest to the
Securities and except that no Security shall be retired if such retirement of
Securities pursuant to this provision would be prohibited by the resolutions or
supplemental indentures referred to in Section 2.03), provided, however, that in
lieu of applying all or any part of such net proceeds or fair market value to
such retirement, the Company may at its option (i) deliver to the Trustee
Securities theretofore purchased or otherwise acquired by the Company, or (ii)
receive credit for Securities theretofore redeemed pursuant to the resolutions
or supplemental indentures referred to in Section 2.03 hereof, which Securities
have not theretofore been made the basis for the reduction of a sinking fund
payment pursuant to Section 13.04 or applied in lieu of retiring Funded Debt
pursuant hereto.  If the Company shall so deliver Securities to the Trustee (or
receive credit for Securities so delivered), the amount of cash which the
Company shall be required to apply to the retirement of Funded Debt pursuant to
this Section 3.06 shall be reduced by an amount equal to the aggregate principal
amount of such Securities.

        SECTION 3.07.  Certificate of the Company.  The Company will furnish to
the Trustee on or before April 1 in each year (beginning with April 1, 199_), so
long as Securities of any series are outstanding hereunder, a brief certificate
(which need not comply with Section 12.05) from the principal executive,
financial or accounting officer of the Company as to his or her knowledge of the
Company's compliance with all conditions and covenants under the Indenture (such
compliance to be determined without regard to any period of grace or requirement
of notice provided under the Indenture).

        SECTION 3.08.     Securityholders' Lists.  If and so long as the
Trustee shall not be the Security registrar for the Securities of any series,
the Company will furnish or cause to be furnished to the Trustee pursuant to
Section 312 of the Trust Indenture Act of 1939:

        (a)   semi-annually, not more than 15 days after each record date for
  each series of Securities, a list, in such form as the Trustee may reasonably
  require, of the names and addresses of the Securityholders of such series of
  Securities as of such record date (and on dates to be determined pursuant to
  Section 2.03 for non-interest bearing Securities in each year); and

        (b)   at such other times as the Trustee may request in writing, within
  thirty days after the receipt by the Company of any such request, a list of
  similar form and content as of a date not more than 15 days prior to the time
  such list is furnished.

        SECTION 3.09.  Reports by the Company.  The Company covenants to file
with the Trustee, within 15 days after the Company is required to file the same
with the Commission, copies of the annual reports and of the information,
documents, and other reports which the Company may be required to file with the
Commission pursuant to Section 13 or Section 15(d) of the Securities Exchange
Act of 1934.

        SECTION 3.10.  Reports by the Trustee.  Any Trustee's report required
under Section 313(a) of the Trust Indenture Act of 1939 shall be transmitted on
or before July 15 in each year following the date hereof, so long as any
Securities are outstanding hereunder, and shall be dated as of a date convenient
to the Trustee no more than 60 nor less than 45 days prior thereto.


                                ARTICLE FOUR.

                 REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS
                            ON EVENT OF DEFAULT.


        SECTION 4.01.     Events of Default.  "Event of Default", whenever used
herein with respect to Securities of any series, means any one of the following
events and such other events as may be established with respect to the
Securities of that series as contemplated by Section 2.03 hereof:

                                     28
<PAGE>
<PAGE>
        (a)   default in the payment of any interest upon any Securities of
  that series when it becomes due and payable, and continuance of such default
  for a period of 30 days; or

        (b)   default in the payment of all or any part of the principal of (or
  premium, if any, on) any Securities of that series as and when the same shall
  become due and payable either at maturity, upon redemption (including
  redemption for the sinking fund), by declaration or otherwise; or

        (c)   default in the performance, or breach, of any covenant of the
  Company in this Indenture (other than a covenant a default in whose
  performance or whose breach is elsewhere in this Section specifically dealt
  with and other than those set forth exclusively in terms of any particular
  series of Securities established as contemplated in this Indenture), and
  continuance of such default or breach for a period of 90 days after there has
  been given, by registered or certified mail, to the Company by the Trustee or
  to the Company and the Trustee by the holders of at least 33% in principal
  amount of the outstanding Securities a written notice specifying such default
  or breach and requiring it to be remedied and stating that such notice is a
  "Notice of Default" hereunder; or

        (d)   a court having jurisdiction in the premises shall enter a decree
  or order for relief in respect of the Company in an involuntary case under
  any applicable bankruptcy, insolvency or other similar law now or hereafter
  in effect, or appointing a receiver, liquidator, assignee, custodian,
  trustee, sequestrator (or similar official) of the Company or for any
  substantial part of its property, or ordering the winding-up or liquidation
  of its affairs and such decree or order shall remain unstayed and in effect
  for a period of 90 consecutive days; or

        (e)   the Company shall commence a voluntary case under any applicable
  bankruptcy, insolvency or other similar law now or hereafter in effect, shall
  consent to the entry of an order for relief in an involuntary case under any
  such law, or shall consent to the appointment of or taking possession by a
  receiver, liquidator, assignee, trustee, custodian, sequestrator (or other
  similar official) of the Company or of any substantial part of its property,
  or shall make any general assignment for the benefit of creditors, or 

                                     29
<PAGE>
<PAGE>
  shall fail generally to pay its debts as they become due.

        If an Event of Default described in clause (a) or (b) or established
pursuant to Section 2.03 occurs and is continuing, then, and in each and every
such case, unless the principal of all of the Securities of such series shall
have already become due and payable, either the Trustee or the holders of not
less than 33% in aggregate principal amount of the Securities of such series
then outstanding hereunder, by notice in writing to the Company (and to the
Trustee if given by Securityholders), may declare the entire principal (or, if
the Securities of that series are Original Issue Discount Securities, such
portion of the principal amount as may be specified in the terms of that series)
of all the Securities of such series and the interest accrued thereon, if any,
to be due and payable immediately, and upon any such declaration the same shall
become immediately due and payable.  If an Event of Default described in clause
(c), (d) or (e) occurs and is continuing, then and in each and every such case,
unless the principal of all the Securities shall have already become due and
payable, either the Trustee or the holders of not less than 33% in aggregate
principal amount of all the Securities then outstanding hereunder (treated as
one class), by notice in writing to the Company (and to the Trustee if given by
Securityholders), may declare the entire principal (or, if any Securities are
Original Issue Discount Securities, such portion of the principal as may be
specified in the terms thereof) of all the Securities then outstanding and
interest accrued thereon, if any, to be due and payable immediately, and upon
any such declaration the same shall become immediately due and payable.

        The foregoing provisions, however, are subject to the condition that
if, at any time after the principal (or, if the Securities are Original Issue
Discount Securities, such portion of the principal as may be specified in the
terms thereof) of the Securities of any series (or of all the Securities, as the
case may be) shall have been so declared due and payable, and before any
judgment or decree for the payment of the moneys due shall have been obtained or
entered as hereinafter provided, the Company shall pay or shall deposit with the
Trustee a sum sufficient to pay all matured installments of interest, if any,
upon all the Securities of any series (or of all the Securities, as the case may
be) and the principal of and premium, if any, on any and all Securities of such
series (or of all the Securities, as the case may be) which shall have become
due otherwise than by acceleration, with interest upon such principal and
premium, if any, and (to the extent that 

                                     30
<PAGE>
<PAGE>

payment of such interest is enforceable under applicable law) on overdue
installments of interest at the same rate as the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) specified in the
Securities of such series, or at the respective rates of interest or Yields to
Maturity of all the Securities, as the case may be, to the date of such payment
or deposit and such amount as shall be sufficient to cover reasonable
compensation to the Trustee and each predecessor Trustee, their respective
agents, attorneys and counsel, as provided in Section 5.06, and if any and all
Events of Default under this Indenture, other than the non-payment of the
principal of or premium, if any, on Securities which shall have become due by
acceleration, shall have been cured, waived or otherwise remedied as provided
herein -- then and in every such case the holders of a majority in aggregate
principal amount of the Securities of such series (or of all the Securities, as
the case may be) then outstanding, by written notice to the Company and to the
Trustee, may waive all defaults with respect to that series (or with respect to
all Securities, as the case may be, in such case, treated as a single class) and
rescind and annul such declaration and its consequences, but no such waiver or
rescission and annulment shall extend to or shall affect any subsequent default
or shall impair any right consequent thereon.

        In case the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
because of such rescission or annulment or for any other reason or shall have
been determined adversely to the Trustee, then and in every such case the
Company, the Trustee and the holders of the Securities shall be restored
respectively to their several positions and rights hereunder, and all rights,
remedies and powers of the Company, the Trustee and the holders of the
Securities shall continue as though no such proceeding had been taken.

        SECTION 4.02.     Payment of Securities on Default; Suit Therefor.  The
Company covenants that (a) in case default shall be made in the payment of any
instalment of interest upon any of the Securities of any series as and when the
same shall become due and payable, and such default shall have continued for a
period of 30 days, or (b) in case default shall be made in the payment of the
principal of or premium, if any, on any of the Securities of any series as and
when the same shall have become due and payable, whether at maturity of the
Securities of that series or upon redemption or by declaration or otherwise --
then, upon demand of the Trustee, the Company will pay to the Trustee, for the
benefit of the holders of the Securities of that 

                                     31

<PAGE>
<PAGE>

series, the whole amount that then shall have become due and payable on all such
Securities of that series for principal and premium, if any, or interest, or
both, as the case may be, with interest upon the overdue principal and premium,
if any, and (to the extent that payment of such interest is enforceable under
applicable law) upon the overdue installments of interest at the rate of
interest or Yield to Maturity (in the case of Original Issue Discount
Securities) borne by the Securities of that series, and, in addition thereto,
such further amount as shall be sufficient to cover the costs and expenses of
collection, including reasonable compensation to the Trustee, its agents,
attorneys and counsel, as provided in Section 5.06.

        In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any actions or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor on such
Securities and collect in the manner provided by law out of the property of the
Company or any other obligor on such Securities wherever situated the moneys
adjudged or decreed to be payable.

        In case there shall be pending proceedings for the bankruptcy or for
the reorganization of the Company or any other obligor on the Securities of any
series under Title 11, United States Code, or any other applicable law, or in
case a receiver or trustee (or similar official) shall have been appointed for
the property of the Company or such other obligor, or in the case of any other
similar judicial proceedings relative to the Company or other obligor upon the
Securities of any series, or to the creditors or property of the Company or such
other obligor, the Trustee, irrespective of whether the principal of the
Securities of any series shall then be due and payable as therein expressed or
by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand pursuant to the provisions of this Section 4.02, shall be
entitled and empowered, by intervention in such proceedings or otherwise, to
file and prove a claim or claims for the whole amount of principal and interest
(or, if the Securities of that series are Original Issue Discount Securities
such portion of the principal amount as may be specified by the terms of that
series) owing and unpaid in respect of the Securities of such series and, in
case of any judicial proceedings, to file such proofs of claim and other papers
or documents as may be necessary or advisable in order to have the claims of 

                                     32
<PAGE>
<PAGE>

the Trustee (including any claim for reasonable compensation to the Trustee and
each predecessor Trustee, and their respective agents, attorneys and counsel, as
provided in Section 5.06) and of the Securityholders allowed in such judicial
proceedings relative to the Company or any other obligor on the Securities of
any series or to the creditors or property of the Company or such other obligor,
unless prohibited by applicable law and regulations, to vote on behalf of the
holders of the Securities of any series in any election of a trustee or a
standby trustee in arrangement, reorganization, liquidation or other bankruptcy
or insolvency proceedings or person performing similar functions in comparable
proceedings, and to collect and receive any moneys or other property payable or
deliverable on any such claims, and to distribute the same after the deduction
of its charges and expenses, except to the extent that such charges or expenses
arise from the negligence or bad faith of the same; and any receiver, assignee
or trustee in bankruptcy or reorganization is hereby authorized by each of the
Securityholders to make such payments to the Trustee, and, in the event that the
Trustee shall consent to the making of such payments directly to the
Securityholders, to pay to the Trustee such amounts as shall be sufficient to
cover reasonable compensation to the Trustee, each predecessor Trustee and their
respective agents, attorneys and counsel, as provided in Section 5.06.

        Nothing herein contained shall be construed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Securityholder any
plan or reorganization, arrangement, adjustment or composition affecting the
Securities of any series or the rights of any holder thereof or to authorize the
Trustee to vote in respect of the claim of any Securityholder in any such
proceeding.

        All rights of action and of asserting claims under this Indenture, or
under any of the Securities, may be enforced by the Trustee without the
possession of any of the Securities, or the production thereof at any trial or
other proceeding relative thereto, and any such suit or proceeding instituted by
the Trustee shall be brought in its own name as trustee of an express trust, and
any recovery of judgment shall be for the ratable benefit of the holders of all
the Securities in respect of which such action was taken.

        In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the holders
of the Securities of the series affected thereby and 

                                     33
<PAGE>
<PAGE>

it shall not be necessary to make any such holders of the Securities parties to
any such proceedings.

        SECTION 4.03.     Application of Moneys Collected by Trustee.  Any
moneys collected by the Trustee shall be applied in the order following, at the
date or dates fixed by the Trustee for the distribution of such moneys, upon
presentation of the several Securities of any series in respect of which moneys
have been collected, and stamping thereon the payment, if only partially paid,
and upon surrender thereof if fully paid:

        FIRST:  To the payment of costs and expenses of collection applicable
  to each such series and reasonable compensation to the Trustee, its agents,
  attorneys and counsel, as provided in Section 5.06;

        SECOND:  In case the principal of the outstanding Securities in respect
  of which moneys have been collected shall not have become due and be unpaid,
  to the payment of interest on the Securities of each such series, in the
  order of the maturity of the installments of such interest, with interest (to
  the extent that payment of such interest is enforceable under applicable law,
  and to the extent that such interest has been collected by the Trustee) upon
  the overdue installments of interest at the respective rates or Yield to
  Maturity (in the case of Original Issue Discount Securities) borne by the
  Securities of each such series, such payments to be made ratably to the
  persons entitled thereto;

        THIRD:  In case the principal of the outstanding Securities in respect
  of which moneys have been collected shall have become due, by declaration or
  otherwise, to the payment of the whole amount then owing and unpaid upon the
  Securities of each such series, for principal and premium, if any, and
  interest, with interest on the overdue principal and premium, if any, and (to
  the extent that payment of such interest is enforceable under applicable law,
  and to the extent that such interest has been collected by the Trustee) upon
  overdue installments of interest at the respective rates or Yield to Maturity
  (in the case of Original Issue Discount Securities) specified in the
  Securities of each such series, and in case such moneys shall be insufficient
  to pay in full the whole amount so due and unpaid upon the Securities of each
  such series, then to the payment of such principal and premium, if any, and
  interest without preference or priority of principal and premium, if any,
  over 

                                     34
<PAGE>
<PAGE>

  interest, or of interest over principal and premium, if any, or of any
  instalment of interest over any other instalment of interest, or of any
  Security of each such series over any other Security of each such series,
  ratably to the aggregate of such principal and premium, if any, and accrued
  and unpaid interest.

        Any surplus then remaining shall be paid to the Company or to such
other person as shall be entitled to receive it.

        SECTION 4.04.  Proceedings by Securityholders.  No holder of any
Security of any series shall have any right by virtue of or by availing of any
provision of this Indenture to institute any suit, action or proceeding in
equity or at law upon or with respect to this Indenture or for the appointment
of a receiver or trustee, or for any other remedy hereunder, unless such holder
previously shall have given to the Trustee written notice of default and of the
continuance thereof, as hereinbefore provided, and unless also the holders of
not less than 33% in aggregate principal amount of the Securities of that series
then outstanding or, in the case of any Event of Default described in clause
(c), (d) or (e) of Section 4.01, 33% in aggregate principal amount of all
Securities then outstanding shall have made written request upon the Trustee to
institute such action, suit or proceeding in its own name as Trustee hereunder
and shall have offered to the Trustee such reasonable indemnity as it may
require against the costs, expenses and liabilities to be incurred therein or
thereby, and the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity shall have failed to institute any such action, suit or
proceeding, it being understood and intended, and being expressly covenanted by
the taker and holder of every Security with every other taker and holder and the
Trustee, that no one or more holders of Securities of any series shall have any
right in any manner whatever by virtue of or by availing of any provision of
this Indenture to affect, disturb or prejudice the rights of any other holder of
Securities, or to obtain or seek to obtain priority over or preference to any
other such holder, or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
holders of Securities of the applicable series.

        Notwithstanding any other provisions in this Indenture, however, the
right of any holder of any Security to receive payment of the principal of,
premium, if any, and interest, if any, on such Security, on or after the same
shall have become due and payable, or to institute suit for 

                                     35
<PAGE>
<PAGE>

the enforcement of any such payment, shall not be impaired or affected without
the consent of such holder.

        SECTION 4.05.     Proceedings by Trustee.  In case of an Event of
Default hereunder the Trustee may in its discretion proceed to protect and
enforce the rights vested in it by this Indenture by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce any
of such rights, either by suit in equity or by action at law or by proceeding in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in aid of the exercise of any power
granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

        SECTION 4.06.     Remedies Cumulative and Continuing.  All powers and
remedies given by this Article Four to the Trustee or to the Securityholders
shall, to the extent permitted by law, be deemed cumulative and not exclusive of
any thereof or of any other powers and remedies available to the Trustee or the
holders of the Securities, by judicial proceedings or otherwise, to enforce the
performance or observance of the covenants and agreements contained in this
Indenture, and no delay or omission of the Trustee or of any holder of any of
the Securities to exercise any right or power accruing upon any default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or an acquiescence
therein; and, subject to the provisions of Section 4.04, every power and remedy
given by this Article Four or by law to the Trustee or to the Securityholders
may be exercised from time to time, and as often as shall be deemed expedient,
by the Trustee or by the Securityholders.

        SECTION 4.07.     Direction of Proceedings and Waiver of Defaults by
Majority of Securityholders.  The holders of a majority in aggregate principal
amount of the Securities of any series at the time outstanding shall have the
right to direct the time, method, and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee with respect to the Securities of such series; provided, however,
that (subject to the provisions of Sections 5.01 and 5.02) the Trustee shall
have the right to decline to follow any such direction if the Trustee shall
determine that the action so directed would be unjustly prejudicial to the
holders not taking part in such direction or if the Trustee being advised by
counsel determines that the action or proceeding so directed may not lawfully be
taken or if the Trustee in good faith by its board of directors or trustees,

                                     36
<PAGE>
<PAGE>

executive committee, or a trust committee of directors or trustees and/or
Responsible Officers shall determine that the action or proceedings so directed
would involve the Trustee in personal liability.  Subject to Section 4.01, the
holders of a majority in aggregate principal amount of the Securities of any
series at the time outstanding may on behalf of the holders of all of the
Securities of such series waive any past default or Event of Default including
any default or Event of Default established pursuant to Section 2.03 (or, in the
case of an event specified in clause (c), (d) or (e) of Section 4.01, the
holders of a majority in aggregate principal amount of all the Securities then
outstanding (voting as one class)) may waive such default or Event of Default,
and its consequences, except a default (a) in the payment of principal of,
premium, if any, or interest on any of the Securities or (b) in respect of
covenants or provisions hereof which cannot be modified or amended without the
consent of the holder of each Security affected.  Upon any such waiver the
Company, the Trustee and the holders of the Securities of that series (or of all
Securities, as the case may be) shall be restored to their former positions and
rights hereunder, respectively; but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent
thereon.  Whenever any default or Event of Default hereunder shall have been
waived as permitted by this Section 4.07, said default or Event of Default shall
for all purposes of the Securities of that series (or of all Securities, as the
case may be) and this Indenture be deemed to have been cured and to be not
continuing.

        SECTION 4.08.  Notice of Defaults.  The Trustee shall, within 90 days
after the occurrence of a default with respect to any of the Securities of any
series, give to the Securityholders of that series, as the names and addresses
of such holders appear upon the Securities register, notice by mail of all
defaults with respect to that series known to the Trustee, unless such defaults
shall have been cured before the giving of such notice (the term "defaults" for
the purpose of this Section 4.08 being hereby defined to be the events specified
in clauses (a), (b), (c), (d) and (e) of Section 4.01, not including periods of
grace, if any, provided for therein, and irrespective of the giving of written
notice specified in clause (c) of Section 4.01); and provided that, except in
the case of default in the payment of the principal of, premium, if any, or
interest on any of the Securities of such series, or in the payment of any
sinking or purchase fund installment with respect to the Securities of such
series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors or trustees, the executive committee, or a trust

                                     37
<PAGE>
<PAGE>

committee of directors or trustees and/or Responsible Officers of the Trustee in
good faith determine that the withholding of such notice is in the interests of
the Securityholders of such series, and provided further, that in the case of
any default of the character specified in Section 4.01(c) no such notice to
Securityholders shall be given until at least 90 days after the occurrence
thereof but shall be given within 120 days after such occurrence.

        SECTION 4.09.     Undertaking to Pay Costs.  All parties to this
Indenture agree, and each holder of any Security by his acceptance thereof shall
be deemed to have agreed, that any court may in its discretion require, in any
suit for the enforcement of any right or remedy under this Indenture, or in any
suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of
such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section 4.09 shall not apply to
any suit instituted by the Trustee, to any suit instituted by any
Securityholder, or group of Securityholders of any series holding in the
aggregate more than 10% in principal amount of the Securities of that series
(or, in the case of any suit relating to or arising under clause (c), (d) or (e)
of Section 4.01, 10% in aggregate principal amount of all Securities)
outstanding, or to any suit instituted by any Securityholder for the enforcement
of the payment of the principal of or premium, if any, or interest on any
Security against the Company on or after the same shall have become due and
payable.


                                ARTICLE FIVE.

                           CONCERNING THE TRUSTEE.


        SECTION 5.01.     Duties and Responsibilities of Trustee.  With respect
to any series of Securities issued hereunder, the Trustee, prior to the
occurrence of an Event of Default with respect to Securities of that series and
after the curing or waiving of all Events of Default which may have occurred
with respect to Securities of that series, undertakes to perform such duties and
only such duties as are specifically set forth in this Indenture with respect to
such series.  In case an Event of Default with respect to the Securities of a
series has occurred (which has not been cured or waived) the Trustee shall
exercise such of the 

                                     38
<PAGE>
<PAGE>

rights and powers vested in it by this Indenture with respect to such series,
and use the same degree of care and skill in their exercise, as a prudent man
would exercise or use under the circumstances in the conduct of his own affairs.

        No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct, except that:

        (a)   prior to the occurrence of an Event of Default with respect to
  the Securities of a series and after the curing or waiving of all Events of
  Default with respect to that series which may have occurred

              (1)   the duties and obligations of the Trustee with respect to
        the Securities of a series shall be determined solely by the express
        provisions of this Indenture, and the Trustee shall not be liable
        except for the performance of such duties and obligations with respect
        to such series as are specifically set forth in this Indenture, and no
        implied covenants or obligations shall be read into this Indenture
        against the Trustee; and 

              (2)   in the absence of bad faith on the part of the Trustee, the
        Trustee may conclusively rely, as to the truth of the statements and
        the correctness of the opinions expressed therein, upon any
        certificates or opinions furnished to the Trustee and conforming to the
        requirements of this Indenture; but, in the case of any such
        certificates or opinions which by any provision hereof are specifically
        required to be furnished to the Trustee, the Trustee shall be under a
        duty to examine the same to determine whether or not they conform to
        the requirements of this Indenture;

        (b)   the Trustee shall not be liable for any error of judgment made in
  good faith by a Responsible Officer or Officers of the Trustee, unless it
  shall be proved that the Trustee was negligent in ascertaining the pertinent
  facts; and

        (c)   the Trustee shall not be liable with respect to any action taken
  or omitted to be taken by it in good faith, in accordance with the direction
  of the Securityholders pursuant to Section 4.07, relating to 

                                     39
<PAGE>
<PAGE>

  the time, method and place of conducting any proceeding for any remedy
  available to the Trustee, or exercising any trust or power conferred upon the
  Trustee, under this Indenture.

        None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there is reasonable ground for believing that the
repayment of such funds or liability is not reasonably assured to it.

        The provisions of this Section 5.01 are in furtherance of and subject
to Sections 315 and 316 of the Trust Indenture Act of 1939.

        SECTION 5.02.  Reliance on Documents, Opinions, etc.  In furtherance of
and subject to the Trust Indenture Act of 1939, and subject to Section 5.01:

        (a)   the Trustee may rely and shall be protected in acting upon any
  resolution, certificate, statement, instrument, opinion, report, notice,
  request, consent, order, bond, note, debenture or other paper or document
  believed by it to be genuine and to have been signed or presented by the
  proper party or parties;

        (b)   any request, direction, order or demand of the Company mentioned
  herein shall be sufficiently evidenced by an Officers' Certificate (unless

  copy thereof certified by the Secretary or an Assistant Secretary of the
  Company;

        (c)   the Trustee may consult with counsel and any advice or Opinion of

  any action taken or omitted by it hereunder in good faith and in accordance
  with such advice or Opinion of Counsel;

        (d)   the Trustee shall be under no obligation to exercise any of the
  rights or powers vested in it by this Indenture at the request, order or

  Indenture, unless such Securityholders shall have offered to the Trustee
  reasonable security or indemnity against the costs, expenses and liabilities
  which may be incurred therein or thereby;

                                     40
<PAGE>
<PAGE>

        (e)   the Trustee shall not be liable for any action taken or omitted
  by it in good faith and believed by it to be authorized or within the
  discretion or rights or powers conferred upon it by this Indenture;

        (f)   prior to the occurrence of an Event of Default hereunder and
  after the curing or waiving of all Events of Default, the Trustee shall not
  be bound to make any investigation into the facts or matters stated in any
  resolution, certificate, statement, instrument, opinion, report, notice,
  request, consent, order, approval, bond, debenture, coupon or other paper or
  document, unless requested in writing to do so by the holders of not less
  than a majority in principal amount of the Securities of all series affected
  then outstanding; provided, however, that if the payment within a reasonable
  time to the Trustee of the costs, expenses or liabilities likely to be
  incurred by it in the making of such investigation is, in the opinion of the
  Trustee, not reasonably assured to the Trustee by the security afforded to it
  by the terms of this Indenture, the Trustee may require reasonable indemnity
  against such expense or liability as a condition to so proceeding;

        (g)   the Trustee may execute any of the trusts or powers hereunder or
  perform any duties hereunder either directly or by or through agents
  (including any Authenticating Agent) or attorneys, and the Trustee shall not
  be responsible for any misconduct or negligence on the part of any such agent
  or attorney appointed by it with due care; and

        (h)   the Trustee shall not be deemed to have knowledge or notice of
  any Event of Default or default with respect to any series of Securities
  unless a Responsible Officer of the Trustee has actual knowledge thereof or
  unless holders of not less than 33% in aggregate principal amount of the
  outstanding Securities of that series shall have notified the Trustee
  thereof.

        SECTION 5.03.  No Responsibility for Recitals, etc.  The recitals
contained herein and in the Securities (except as to the date of the Security
and except in the certificate of authentication of the Trustee or the
Authenticating Agent) shall be taken as the statements of the Company, and the
Trustee and the Authenticating Agent assume no responsibility for the
correctness of the same.  The Trustee and the Authenticating Agent make no 

                                     41
<PAGE>
<PAGE>

representations as to the validity or sufficiency of this Indenture or of the
Securities.  The Trustee and the Authenticating Agent shall not be accountable
for the use or application by the Company of any Securities or the proceeds of
any Securities authenticated and delivered by the Trustee or the Authenticating
Agent in conformity with the provisions of this Indenture.

        SECTION 5.04.  Trustee, Authenticating Agent, Paying Agents, Transfer
Agents or Registrar May Own Securities.  The Trustee or any Authenticating Agent
or any paying agent or any transfer agent or any Securities registrar, in its
individual or any other capacity, may become the owner or pledgee of Securities
with the same rights it would have if it were not Trustee, Authenticating Agent,
paying agent, transfer agent or Securities registrar.

        SECTION 5.05.  Moneys to be Held in Trust.  Subject to the provisions
of Section 10.04, all moneys received by the Trustee or any paying agent shall,
until used or applied as herein provided, be held in trust for the purpose for
which they were received, but need not be segregated from other funds except to
the extent required by law.  The Trustee and any paying agent shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.  So long as no Event of Default shall have occurred and
be continuing, all interest allowed on any such moneys shall be paid from time
to time upon the written order of the Company, signed by the Chairman of the
Board of Directors, the President, any Vice President, the Treasurer or any
Assistant Treasurer of the Company.

        SECTION 5.06.  Compensation and Expenses of Trustee.  The Company
covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, reasonable compensation (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust), and the Company will pay or reimburse the Trustee upon its request for
all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any of the provisions of this Indenture (including
the reasonable compensation and the expenses and disbursements of its counsel
and of all persons not regularly in its employ and any amounts it paid to any
Authenticating Agent pursuant to Section 5.12).  Notwithstanding anything in
this Indenture to the contrary, the Company will have no obligation to reimburse
the Trustee for any such expense, disbursement or advance arising from the
negligence or bad faith of the Trustee.  If any property other than cash shall
at any time be subject to the lien of 

                                     42
<PAGE>
<PAGE>

this Indenture, the Trustee, if and to the extent authorized by a receivership
or bankruptcy court of competent jurisdiction or by the supplemental instrument
subjecting such property to such lien, shall be entitled to make advances for
the purpose of preserving such property or of discharging tax liens or other
prior liens or encumbrances thereon.  The Company also covenants to indemnify
each of the Trustee and any predecessor Trustee for, and to hold each of them
harmless against, any loss, liability or expense arising out of or in connection
with the acceptance or administration of this trust and the performance of its
duties hereunder, including the costs and expenses of defending itself against
any claim of liability in the premises, except to the extent such loss,
liability or expense is due to the negligence or bad faith of the Trustee or
such predecessor Trustee.  The obligations of the Company under this Section
5.06 to compensate the Trustee and to pay or reimburse the Trustee for expenses,
disbursements and advances shall constitute additional indebtedness hereunder. 
Such additional indebtedness shall be secured by a claim prior to that of the
Securities upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the benefit of the holders of particular
Securities.

        SECTION 5.07.  Officers' Certificate as Evidence.  Except as otherwise
provided in Section 5.01 and 5.02, whenever in the administration of the
provisions of this Indenture the Trustee shall deem it necessary or desirable
that a matter be proved or established prior to taking or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officers' Certificate delivered to the Trustee, and such Certificate, in the
absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken or omitted by it under the
provisions of this Indenture upon the faith thereof.

        SECTION 5.08.  Eligibility of Trustee.  The Trustee hereunder shall at
all times be a corporation having a combined capital and surplus of at least
$5,000,000, and which is eligible in accordance with the provisions of Section
310(a) of the Trust Indenture Act of 1939.  If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of a Federal, State, Territorial or District of Columbia supervising or
examining authority, then for the purposes of this Section 5.08 the combined
capital and surplus of such 

                                     43
<PAGE>
<PAGE>

corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.

        SECTION 5.09.  Resignation or Removal of Trustee.  (a)  The Trustee, or
any trustee or trustees hereafter appointed, may at any time resign with respect
to one or more or all series of Securities by giving written notice of such
resignation to the Company and by mailing notice thereof to the holders of the
applicable series of Securities at their addresses as they shall appear on the
Securities register.  Upon receiving such notice of resignation, the Company
shall promptly appoint a successor trustee or trustees with respect to the
applicable series by written instrument, in duplicate, executed by order of its
Board of Directors, one copy of which instrument shall be delivered to the
resigning Trustee and one copy to the successor trustee.  If no successor
trustee shall have been so appointed with respect to any series of Securities
and have accepted appointment within 60 days after the mailing of such notice of
resignation to the affected Securityholders, the resigning Trustee may petition
any court of competent jurisdiction for the appointment of a successor trustee,
or any Securityholder who has been a bona fide holder of a Security or
Securities of the applicable series for at least six months may, subject to the
provisions of Section 4.09, on behalf of himself and all others similarly
situated, petition any such court for the appointment of a successor trustee. 
Such court may thereupon, after such notice, if any, as it may deem proper and
prescribe, appoint a successor trustee.

        (b)   In case at any time any of the following shall occur -

              (1)   the Trustee shall fail to comply with the provisions of
        Section 310(b) of the Trust Indenture Act of 1939 with respect to any
        series of Securities after written request therefor by the Company or
        by any Securityholder who has been a bona fide holder of a Security or
        Securities for at least six months, or

              (2)   the Trustee shall cease to be eligible in accordance with
        the provisions of Section 310(a) of the Trust Indenture Act of 1939 and
        shall fail to resign after written request therefor by the Company or
        by any such Securityholder, or

              (3)   the Trustee shall become incapable of acting, or shall be
        adjudged a bankrupt or 

                                     44
<PAGE>
<PAGE>

        insolvent, or a receiver of the Trustee or of its property shall be
        appointed, or any public officer shall take charge or control of the
        Trustee or of its property or affairs for the purpose of
        rehabilitation, conservation or liquidation,

then, in any such case, the Company may remove such Trustee with respect to any
series of Securities and appoint a successor trustee by written instrument, in
duplicate, executed by order of the Board of Directors, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the
successor trustee, or, subject to Section 315(e) of the Trust Indenture Act of
1939, any Securityholder who has been a bona fide holder of a Security or
Securities of a particular series for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of such Trustee with respect to such series of
Securities and the appointment of a successor trustee.  Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe,
remove the Trustee and appoint a successor trustee.

        (c)   The holders of a majority in aggregate principal amount of the
Securities of one or more series (each series voting as a class) or all series
(voting as one class) at the time outstanding may at any time remove the Trustee
with respect to the applicable series of Securities or all series, as the case
may be, and nominate a successor trustee with respect to the applicable series
of Securities or all series, as the case may be, which shall be deemed appointed
as successor trustee with respect to the applicable series unless within ten
days after such nomination the Company objects thereto, in which case the
Trustee so removed or any Securityholder of the applicable series, upon the
terms and conditions and otherwise as in subdivision (a) of this Section 5.09
provided, may petition any court of competent jurisdiction for an appointment of
a successor trustee with respect to such series.

        (d)   Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 5.09 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 5.10.

        SECTION 5.10.  Acceptance by Successor Trustee.  Any successor trustee
appointed as provided in Section 5.09 shall execute, acknowledge and deliver to
the Company and to its predecessor Trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or 

                                     45
<PAGE>
<PAGE>

removal of the predecessor Trustee with respect to all or any applicable series
shall become effective and such successor trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, duties and
obligations with respect to such series of its predecessor hereunder, with like
effect as if originally named as trustee herein; but, nevertheless, on the
written request of the Company or of the successor trustee, the Trustee ceasing
to act shall, upon payment of any amounts then due it pursuant to the provisions
of Section 5.06, execute and deliver an instrument transferring to such
successor trustee all the rights and powers of the Trustee so ceasing to act. 
Upon request of any such successor trustee, the Company shall execute any and
all instruments in writing for more fully and certainly vesting in and
confirming to such successor trustee all such rights and powers.  Any Trustee
ceasing to act shall, nevertheless, retain a claim upon all property or funds
held or collected by such Trustee to secure any amounts then due it pursuant to
the provisions of Section 5.06.

        If a successor trustee is appointed with respect to the Securities of
one or more (but not all) series, the Company, the predecessor Trustee and each
successor trustee with respect to the Securities of any applicable series shall
execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the predecessor Trustee with respect to the
Securities of any series as to which the predecessor Trustee is not retiring
shall continue to be vested in the predecessor Trustee, and shall add to or
change any of the provisions of this Indenture as shall be necessary to provide
for or facilitate the administration of the trust hereunder by more than one
trustee, it being understood that nothing herein or in such supplemental
indenture shall constitute such trustees co-trustees of the same trust and that
each such trustee shall be trustee of a trust or trusts hereunder separate and
apart from any trust or trusts hereunder administered by any other such trustee.

        Upon acceptance of appointment by a successor trustee as provided in
this Section 5.10, the Company shall mail notice of the succession of such
trustee hereunder to the holders of Securities of any applicable series at their
addresses as they shall appear on the Securities register.  If the Company fails
to mail such notice within ten days after the acceptance of appointment by the
successor trustee, the successor trustee shall cause such notice to be mailed at
the expense of the Company.

                                     46

        SECTION 5.11.  Succession by Merger, etc.  Any corporation into which
the Trustee may be merged or converted or with which it may be consolidated, or
any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or
substantially all of the corporate trust business of the Trustee, shall be the
successor of the Trustee hereunder without the execution or filing of any paper
or any further act on the part of any of the parties hereto.

        In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities of any series shall have
been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor Trustee, and deliver
such Securities so authenticated; and in case at that time any of the Securities
of any series shall not have been authenticated, any successor to the Trustee
may authenticate such Securities either in the name of any predecessor hereunder
or in the name of the successor trustee; and in all such cases such certificates
shall have the full force which it is anywhere in the Securities of such series
or in this Indenture provided that the certificate of the Trustee shall have;
provided, however, that the right to adopt the certificate of authentication of
any predecessor Trustee or authenticate Securities of any series in the name of
any predecessor Trustee shall apply only to its successor or successors by
merger, conversion or consolidation.

        SECTION 5.12.     Authenticating Agents.  There may be one or more
Authenticating Agents appointed by the Trustee upon the request of the Company
with power to act on the Trustee's behalf and subject to its direction in the
authentication and delivery of Securities of any series issued upon exchange or
transfer thereof as fully to all intents and purposes as though any such
Authenticating Agent had been expressly authorized to authenticate and deliver
Securities of such series; provided, that the Trustee shall have no liability to
the Company for any acts or omissions of the Authenticating Agent with respect
to the authentication and delivery of Securities of any series.  Any such
Authenticating Agent shall at all times be a corporation organized and doing
business under the laws of the United States or of any State or Territory
thereof or of the District of Columbia authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of at least
$5,000,000 (except that such requirement as to combined capital and surplus
shall not apply in the case that the Authenticating Agent is First Chicago Trust

                                     47

<PAGE>

Company of New York) and being subject to supervision or examination by Federal,
State, Territorial or District of Columbia authority.  If such corporation
publishes reports of condition at least annually pursuant to law or the
requirements of such authority, then for the purposes of this Section 5.12 the
combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published.  If at any time an Authenticating Agent shall cease to be eligible
in accordance with the provisions of this Section, it shall resign immediately
in the manner and with the effect herein specified in this Section.

        Any corporation into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate trust business
of any Authenticating Agent, shall be the successor of such Authenticating Agent
hereunder, if such successor corporation is otherwise eligible under this
Section 5.12, without the execution or filing of any paper or any further act on
the part of the parties hereto or such Authenticating Agent.

        Any Authenticating Agent may at any time resign with respect to one or
more or all series of Securities by giving written notice of resignation to the
Trustee and to the Company.  The Trustee may at any time terminate the agency of
any Authenticating Agent with respect to one or more or all series of Securities
by giving written notice of termination to such Authenticating Agent and to the
Company.  Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any Authenticating Agent shall cease to be
eligible under this Section 5.12, the Trustee may, and upon the request of the
Company shall, promptly appoint a successor Authenticating Agent with respect to
the applicable series eligible under this Section 5.12, shall give written
notice of such appointment to the Company and shall mail notice of such
appointment to all holders of the applicable series of Securities as the names
and addresses of such holders appear on the Securities register.  Any successor
Authenticating Agent with respect to all or any series upon acceptance of its
appointment hereunder shall become vested with all rights, powers, duties and
responsibilities with respect to such series of its predecessor hereunder, with
like effect as if originally named as Authenticating Agent herein.

        The Trustee agrees to pay to any Authenticating Agent from time to time
reasonable compensation for its 

                                     48
<PAGE>
<PAGE>

services, and the Trustee shall be entitled to be reimbursed for such payments,
subject to Section 5.06.  Any Authenticating Agent shall have no responsibility
or liability for any action taken by it as such in accordance with the
directions of the Trustee.

        If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternate
certificate of authentication in the following form:

        This is one of the Securities of the series designated therein referred
  to in the within-mentioned Indenture.

                    THE FIRST NATIONAL BANK OF CHICAGO,
                      as Trustee


                    By                                 
                          as Authenticating Agent
                            for the Trustee


                    By                                 
                         Authorized Officer


                                ARTICLE SIX.

                       CONCERNING THE SECURITYHOLDERS.


        SECTION 6.01.  Action by Securityholders.  Whenever in this Indenture
it is provided that the holders of a specified percentage in aggregate principal
amount of the Securities of any or all series may take any action (including the
making of any demand or request, the giving of any notice, consent or waiver or
the taking of any other action) the fact that at the time of taking any such
action the holders of such specified percentage have joined therein may be
evidenced (a) by any instrument or any number of instruments of similar tenor
executed by such Securityholders in person or by agent or proxy appointed in
writing, or (b) by the record of such holders of Securities voting in favor
thereof at any meeting of such Securityholders duly called and held in
accordance with the provisions of Article Seven, or (c) by a combination of such
instrument or instruments and any such record of such a meeting of such
Securityholders.

                                     49
<PAGE>
<PAGE>

        SECTION 6.02.  Proof of Execution by Securityholders.  Subject to the
provisions of Sections 5.01, 5.02 and 7.05, proof of the execution of any
instrument by a Securityholder or his agent or proxy shall be sufficient if made
in accordance with such reasonable rules and regulations as may be prescribed by
the Trustee or in such manner as shall be satisfactory to the Trustee.  The
ownership of Securities shall be proved by the Securities register or by a
certificate of the Securities registrar.
The Company may set a record date for purposes of determining the identity of
holders of Securities of any series entitled to vote or consent to any action
referred to in Section 6.01, which record date may be set at any time or from
time to time by notice to the Trustee, for any date or dates (in the case of any
adjournment or reconsideration) not more than 60 days nor less than five days
prior to the proposed date of such vote or consent, and thereafter,
notwithstanding any other provisions hereof, only holders of Securities of such
series of record on such record date shall be entitled to so vote or give such
consent or revoke such vote or consent.

        The record of any Securityholders' meeting shall be provided in the
manner provided in Section 7.06.

        SECTION 6.03.  Who are Deemed Absolute Owners.  The Company, the
Trustee, any Authenticating Agent, any paying agent, any transfer agent and any
Securities registrar may deem the person in whose name such Security shall be
registered upon the Securities register to be, and may treat him as, the
absolute owner of such Security (whether or not such Security shall be overdue
and notwithstanding any notation of ownership or other writing thereon) for the
purpose of receiving payment of or on account of the principal of, premium, if
any, and any interest on such Security and for all other purposes; and neither
the Company nor the Trustee nor any Authenticating Agent nor any paying agent
nor any transfer agent nor any Securities registrar shall be affected by any
notice to the contrary.  All such payments so made to any holder for the time
being or upon his order shall be valid, and, to the extent of the sum or sums so
paid, effectual to satisfy and discharge the liability for moneys payable upon
any such Security.

        SECTION 6.04.  Securities Owned by Company Deemed Not Outstanding.  In
determining whether the holders of the requisite aggregate principal amount of
Securities have concurred in any direction, consent or waiver under this
Indenture, Securities which are owned by the Company or any other obligor on the
Securities or by any person directly or 

                                     50
<PAGE>
<PAGE>

indirectly controlling or controlled by or under direct or indirect common
control with the Company or any other obligor on the Securities shall be
disregarded and deemed not to be outstanding for the purpose of any such
determination; provided that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, consent or waiver, only
Securities which a Responsible Officer knows are so owned shall be so
disregarded.  Securities so owned which have been pledged in good faith may be
regarded as outstanding for the purposes of this Section 6.04 if the pledgee
shall establish to the satisfaction of the Trustee the pledgee's right to vote
such Securities and that the pledgee is not the Company or any such other
obligor or person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company or any such other obligor. 
Upon request of the Trustee, the Company shall furnish to the Trustee promptly
an Officers' Certificate listing and identifying all Securities, if any, known
by the Company to be owned or held by or for the account of any of the above-
described persons; and, subject to the provisions of Section 5.01, the Trustee
shall be entitled to accept such Officers' Certificate as conclusive evidence of
the facts therein set forth and of the fact that all Securities not listed are
outstanding for the purpose of any such determination.

        SECTION 6.05.  Revocation of Consents; Future Holders Bound.  At any
time prior to (but not after) the evidencing to the Trustee, as provided in
Section 6.01, of the taking of any action by the holders of the percentage in
aggregate principal amount of the Securities specified in this Indenture in
connection with such action, any holder of a Security (or any Security issued in
whole or in part in exchange or substitution therefor) who consented to such
action may, by filing written notice with the Trustee at its principal office
and upon proof of holding as provided in Section 6.02, revoke such action so far
as concerns such Security (or so far as concerns the principal amount
represented by any exchanged or substituted Security).  Except as aforesaid any
such action taken by the holder of any Security shall be conclusive and binding
upon such holder and upon all future holders and owners of such Security, and of
any Security issued in exchange or substitution therefor, irrespective of
whether or not any notation in regard thereto is made upon such Security or any
Security issued in exchange or substitution therefor.  Any action taken by the
holders of the percentage in aggregate principal amount of the Securities
specified in this Indenture in connection with such action shall be conclusively
binding upon the Company, the Trustee with

respect to such Securities and the holders of such Securities.

any or all series may be called at any time and from time to time pursuant to
the provisions of this Article Seven for any of the following purposes:

              (a)  to give any notice to the Company or to the Trustee, or to
        give any directions to the Trustee, or to consent to the waiving of any
        default hereunder and its consequences, or to take any other action
        authorized to be taken by Securityholders pursuant to any of the
        provisions of Article Four;

              (b)  to remove the Trustee and nominate a successor Trustee
        pursuant to the provisions of Article Five;

        such Securities under any other provisions of this Indenture or under
        applicable law.

        SECTION 7.02.  Call of Meetings by Trustee.  The Trustee may at any
time call a meeting of Securityholders of any or all series to take any action
specified in Section 7.01, to be held at such time and at such place in the

Notice of every meeting of the Securityholders of any or all series, setting
forth the record date, time and the place of such meeting and in general terms
the action proposed to be taken at such meeting, shall be mailed to holders of

<PAGE>

        SECTION 7.03.  Call of Meetings by Company or Securityholders.  In case
at any time the Company pursuant to a resolution of the Board of Directors, or
the holders of at least 20% in aggregate principal amount of the Securities of
any or all series, as the case may be, then outstanding, shall have requested
the Trustee to call a meeting of Securityholders of any or all series, as the
case may be, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have mailed the
notice of such meeting within 20 days after receipt of such request, then the
Company or such Securityholders, as the case may be, may determine the time and
the place in said Borough of Manhattan for such meeting and may call such
meeting to take any action authorized in Section 7.01, by mailing notice thereof
as provided in Section 7.02.

        SECTION 7.04.  Qualifications for Voting.  To be entitled to vote at
any meeting of Securityholders a Person shall be (a) a holder of one or more
Securities with respect to which the meeting is being held or (b) a Person
appointed by an instrument in writing as proxy by such a holder of one or more
such Securities.  The only Persons who shall be entitled to be present or to
speak at any meeting of Securityholders shall be the Persons entitled to vote at
such meeting and their counsel and any representatives of the Trustee and its
counsel and any representatives of the Company and its counsel.

        SECTION 7.05.  Regulations.  Notwithstanding any other provisions of
this Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Securityholders, in regard to proof of the holding
of Securities and of the appointment of proxies, and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall think fit.

        The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Securityholders as provided in Section 7.03, in which case the
Company or the Securityholders calling the meeting, as the case may be, shall in
like manner appoint a temporary chairman.  A permanent chairman and a permanent
secretary of the meeting shall be elected by majority vote of the meeting.

                                     53
<PAGE>
<PAGE>

        Subject to the provisions of Section 6.04, at any meeting each holder
of Securities with respect to which such meeting is being held or proxy therefor
shall be entitled to one vote for each $1,000 principal amount (or in the case
of Original Issue Discount Securities, such principal amount to be determined as
provided in the definition of "Outstanding") of Securities held or represented
by him; provided, however, that no vote shall be cast or counted at any meeting
in respect of any Security challenged as not outstanding and ruled by the
chairman of the meeting to be not outstanding.  The chairman of the meeting
shall have no right to vote other than by virtue of Securities held by him or
instruments in writing as aforesaid duly designating him as the person to vote
on behalf of other Securityholders.  At any meeting of Securityholders, the
presence of Persons holding or representing Securities in an aggregate principal
amount sufficient to take action on the business for the transaction of which
such meeting was called shall constitute a quorum, but, if less than a quorum is
present, the Persons holding or representing a majority in aggregate principal
amount of the Securities represented at the meeting and entitled to vote may
adjourn such meeting with the same effect, for all intents and purposes, as
though a quorum had been present.  Any meeting of Securityholders duly called
pursuant to the provisions of Section 7.02 or 7.03 may be adjourned from time to
time by a majority of those present, whether or not constituting a quorum, and
the meeting may be held as so adjourned without further notice.

        SECTION 7.06.  Voting.  The vote upon any resolution submitted to any
meeting of holders of Securities with respect to which such meeting is being
held shall be by written ballots on which shall be subscribed the signatures of
such holders or of representatives by proxy and the serial number or numbers of
the Securities held or represented by them.  The permanent chairman of the
meeting shall appoint two inspectors of votes who shall count all votes cast at
the meeting for or against any resolution and who shall make and file with the
secretary of the meeting their verified written reports in triplicate of all
votes cast at the meeting.  A record in duplicate of the proceedings of each
meeting of Securityholders shall be prepared by the secretary of the meeting and
there shall be attached to said record the original reports of the inspectors of
votes on any vote by ballot taken thereat and affidavits by one or more persons
having knowledge of the facts setting forth a copy of the notice of the meeting
and showing that said notice was mailed as provided in Section 7.02.  The record
shall show the serial numbers of the Securities voting in favor of or against
any resolution.  The record shall be signed and verified by the affidavits of

                                     54
<PAGE>
<PAGE>

the permanent chairman and secretary of the meeting and one of the duplicates
shall be delivered to the Company and the other to the Trustee to be preserved
by the Trustee, the latter to have attached thereto the ballots voted at the
meeting.

        Any record so signed and verified shall be conclusive evidence of the
matters therein stated.



                               ARTICLE EIGHT.

                          SUPPLEMENTAL INDENTURES.

        SECTION 8.01.  Supplemental Indentures without Consent of
Securityholders.  The Company, when authorized by a resolution of the Board of
Directors, and the Trustee may from time to time and at any time enter into an
indenture or indentures supplemental hereto for one or more of the following
purposes:

        (a)   to evidence the succession of another corporation to the
  Company, or successive succession, and the assumption by the successor
  corporation of the covenants, agreements and obligations of the Company
  pursuant to Article Nine hereof;

        (b)   to add to the covenants of the Company such further covenants,
  restrictions or conditions for the protection of the holders of all or any
  series of Securities (and if such covenants are to be for the benefit of
  less than all series of Securities stating that such covenants are
  expressly being included for the benefit of such series) as the Board of
  Directors and the Trustee shall consider to be for the protection of the
  holders of such Securities, and to make the occurrence, or the occurrence
  and continuance, of a default in any of such additional covenants,
  restrictions or conditions a default or an Event of Default permitting the
  enforcement of all or any of the several remedies provided in this
  Indenture as herein set forth; provided, however, that in respect of any
  such additional covenant, restriction or condition such supplemental
  indenture may provide for a particular period of grace after default
  (which period may be shorter or longer than that allowed in the case of
  other defaults) or may provide for an immediate 

                                     55
<PAGE>
<PAGE>

  enforcement upon such default or may limit the remedies available to the
  Trustee upon such default;

        (c)   to provide for the issuance under this Indenture of Securities
  in coupon form (including Securities registrable as to principal only) and
  to provide for exchangeability of such Securities with the Securities
  issued hereunder in fully registered form and to make all appropriate
  changes for such purpose;

        (d)   to convey, transfer, assign, mortgage or pledge to the Trustee
  as security for the Securities any property or assets which the Company
  may desire or may be required to convey, transfer, assign, mortgage or
  pledge in accordance with the provisions of Section 3.05 or Section 9.03;

        (e)   to cure any ambiguity or to correct or supplement any
  provision contained herein or in any supplemental indenture which may be
  defective or inconsistent with any other provision contained herein or in
  any supplemental indenture, or to make other provisions in regard to
  matters or questions arising under this Indenture or to make any other
  changes hereto; provided that any such action shall not adversely affect
  the interests of the holders of the Securities in any material respect;

        (f)   to establish the form or terms of Securities of any series as
  permitted by Sections 2.01 and 2.03; and

        (g)   to evidence and provide for the acceptance of appointment
  hereunder by a successor trustee with respect to the Securities of one or
  more series and to add to or change any of the provisions of this
  Indenture as shall be necessary to provide for or facilitate the
  administration of the trusts hereunder by more than one trustee, pursuant
  to the requirements of Section 5.10.

        The Trustee is hereby authorized to join with the Company in the
execution of any such supplemental indenture, to make any further appropriate
agreements and stipulations which may be therein contained and to accept the
conveyance, transfer and assignment of any property thereunder, but the Trustee
shall not be obligated to, but may in its 

                                     56
<PAGE>
<PAGE>

discretion, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

        Any supplemental indenture authorized by the provisions of this Section
8.01 may be executed by the Company and the Trustee without the consent of the
holders of any of the Securities at the time outstanding, notwithstanding any of
the provisions of Section 8.02.

        SECTION 8.02.  Supplemental Indentures with Consent of Securityholders.
With the consent (evidenced as provided in Section 6.01) of the holders of not
less than 66 2/3% in aggregate principal amount of the Securities at the time
outstanding of all series affected by such supplemental indenture (voting as a
class), the Company, when authorized by a resolution of the Board of Directors,
and the Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental indenture or of modifying in any manner the rights of the
holders of the Securities of each series so affected; provided, however, that no
such supplemental indenture shall (i) extend the final maturity of any Security,
or reduce the rate or extend the time of payment of interest thereon, or reduce
the principal amount thereof or any premium thereon, or reduce any amount
payable on redemption thereof, or make the principal thereof or any interest or
premium thereon payable in any coin or currency other than that provided in the
Securities, or reduce the amount of the principal of an Original Issue Discount
Security that would be due and payable upon an acceleration of the maturity
thereof pursuant to Section 4.01 or the amount thereof provable in bankruptcy
pursuant to Section 4.02, or impair or affect the right of any Securityholder to
institute suit for payment thereof or the right of repayment, if any, at the
option of the holder, without the consent of the holder of each Security so
affected, or (ii) reduce the aforesaid percentage of Securities the holders of
which are required to act pursuant to Section 4.07 or to consent to any such
supplemental indenture, without the consent of the holders of each Security then
affected.

        A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for
the benefit of one or more particular series of Securities, or which modifies
the rights of Securityholders of such series with respect to such covenant or
provision, shall be deemed not

                                     57
<PAGE>
<PAGE>

to affect the rights under this Indenture of the Securityholders of any other
series.

        Upon the request of the Company accompanied by a copy of a resolution
of the Board of Directors certified by its Secretary or Assistant Secretary
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of Securityholders as
aforesaid, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.

        It shall not be necessary for the consent of the Securityholders under
this Section 8.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

        SECTION 8.03.  Compliance with Trust Indenture Act; Effect of
Supplemental Indentures.  Any supplemental indenture executed pursuant to the
provisions of this Article Eight shall comply with the Trust Indenture Act of
1939, as then in effect.  Upon the execution of any supplemental indenture
pursuant to the provisions of this Article Eight, this Indenture shall be and be
deemed to be modified and amended in accordance therewith and the respective
rights, limitations of rights, obligations, duties and immunities under this
Indenture of the Trustee, the Company and the holders of Securities of each
series affected thereby shall thereafter be determined, exercised and enforced
hereunder subject in all respects to such modifications and amendments and all
the terms and conditions of any such supplemental indenture shall be and be
deemed to be part of the terms and conditions of this Indenture for any and all
purposes.

        SECTION 8.04.  Notation on Securities.  Securities of any series
authenticated and delivered after the execution of any supplemental indenture
affecting such series pursuant to the provisions of this Article Eight may bear
a notation in form approved by the Trustee as to any matter provided for in such
supplemental indenture.  If the Company or the Trustee shall so determine, new
Securities of any series so modified as to conform, in the opinion of the
Trustee and the Board of Directors, to any modification of this Indenture
contained in any such supplemental indenture may be prepared and executed by the
Company, authenticated 

                                     58
<PAGE>
<PAGE>
by the Trustee or the Authenticating Agent and delivered in exchange for the
Securities of any series then outstanding.

        SECTION 8.05.  Evidence of Compliance of Supplemental Indenture to be
Furnished Trustee.  The Trustee, subject to the provisions of Section 5.01 and
5.02, may receive an Officers' Certificate and an Opinion of Counsel as
conclusive evidence that any supplemental indenture executed pursuant hereto
complies with the requirements of this Article Eight.


                                ARTICLE NINE.

             CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 
                               BY THE COMPANY.

        SECTION 9.01.  Consolidations and Mergers of Company and Conveyances
Permitted Subject to Certain Conditions.  Subject to the provisions of Section
9.03, nothing contained in this Indenture or in any of the Securities shall
prevent any consolidation or merger of the Company with or into any other
corporation or corporations, or successive consolidations or mergers in which
the Company or its successor or successors shall be a party or parties or shall
prevent any sale or conveyance of all or substantially all of the property of
the Company to any other corporation authorized to acquire and operate the same;
provided, that in any such case, (i) either the Company shall be the continuing
corporation, or the successor corporation (if other than the Company) shall be a
corporation organized and existing under the laws of the United States of
America or a State or Territory thereof or the District of Columbia and such
corporation shall expressly assume the due and punctual payment of the principal
of, and premium, if any, and interest on all the Securities, according to their
tenor, and the due and punctual performance and observance of all of all the
covenants and conditions of this Indenture to be performed by the Company by
supplemental indenture satisfactory to the Trustee, executed and delivered to
the Trustee by such corporation, and (ii) the Company or such successor
corporation, as the case may be, shall not, immediately after such merger or
consolidation, or such sale or conveyance, be in default in the performance of
any such covenant or condition and shall not immediately thereafter have
outstanding any secured Debt (as defined in Section 3.05) not expressly
permitted by the provisions of Section 3.05 unless the provisions of Section
9.03 shall previously have been complied with.

                                     59
<PAGE>

        SECTION 9.02.  Successor Corporation to be Substituted for Company.  In
case of any such consolidation, merger, sale or conveyance (other than a
conveyance by way of lease) and upon any such assumption by the successor
corporation, such successor corporation shall succeed to and be substituted for
the Company, with the same effect as if it had been named herein as the party of
the first part, and the Company thereupon shall be relieved of any further
liability or obligation hereunder or upon the Securities and may thereupon or at
any time thereafter be dissolved, wound up or liquidated.  Such successor
corporation thereupon may cause to be signed, and may issue either in its own
name or in the name of MascoTech, Inc., any or all of the Securities issuable
hereunder which theretofore shall not have been signed by the Company and
delivered to the Trustee or the Authenticating Agent; and, upon the order of
such successor corporation (instead of the Company) and subject to all the
terms, conditions and limitations in this Indenture prescribed, the Trustee or
the Authenticating Agent shall authenticate and deliver any Securities which
previously shall have been signed and delivered by the officers of the Company
to the Trustee or the Authenticating Agent for authentication, and any
Securities which such successor corporation thereafter shall cause to be signed
and delivered to the Trustee or the Authenticating Agent for that purpose.  All
the Securities so issued shall in all respects have the same legal rank and
benefit under this Indenture as the Securities theretofore or thereafter issued
in accordance with the terms of this Indenture as though all of such Securities
had been issued at the date of the execution hereof.

        In case of any such consolidation, merger, sale or conveyance, such
changes in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

        SECTION 9.03.  Securities to be Secured in Certain Events.  If, upon
any such consolidation or merger of the Company with or into any other
corporation, or upon any sale or conveyance of the property of the Company as an
entirety or substantially as an entirety to any other corporation, any Principal
Property or any shares of stock or indebtedness of any Consolidated Subsidiary
owning any Principal Property owned immediately prior thereto would thereupon
become subject to any mortgage (as defined in Section 3.05), unless the Company
could create such mortgage pursuant to Section 3.05 without equally and ratably
securing the Securities, the Company, prior to or simultaneously with such
consolidation, merger, sale or conveyance, will secure the Securities
outstanding 

                                     60
<PAGE>
<PAGE>

hereunder, equally and ratably with any other obligation of the Company or any
such Subsidiary then entitled thereto, prior to the Debt (as defined in Section
3.05) secured by such mortgage.

        SECTION 9.04.  Evidence to be Furnished Trustee.  The Trustee, subject
to the provisions of Sections 5.01 and 5.02, may receive and rely upon an
Officers' Certificate and an Opinion of Counsel as conclusive evidence that any
consolidation, merger, sale or conveyance, and any such assumption complies with
the provisions of this Article Nine.


                                ARTICLE TEN.

                  SATISFACTION AND DISCHARGE OF INDENTURE.

        SECTION 10.01.  Discharge of Indenture.  When (a) the Company shall
have paid or caused to be paid the principal of and interest on all Securities
of any series outstanding hereunder, as and when the same shall have become due
and payable, (b) the Company shall deliver to the Trustee for cancellation all
Securities of any series theretofore authenticated (other than any Securities of
such series which shall have been destroyed, lost or stolen and which shall have
been replaced or paid as provided in Section 2.08) and not theretofore
cancelled, or (c) with respect to any series of Securities which, under the
terms specified in the resolution or supplemental indenture or indentures
referred to in Section 2.03, pursuant to which such series is created, can be
discharged prior to maturity, the Company shall deposit with the Trustee, in
trust, cash and/or a principal amount of obligations of or directly guaranteed
by the United States of America maturing or redeemable at the option of the
holder thereof not later than the date fixed for payment or redemption of all
outstanding Securities of such series which, together with the income to be
earned on such obligations prior to such date, equals the principal amount of
(and any applicable premium on) all such Securities of such series not
theretofore cancelled or delivered to the Trustee for cancellation, with
interest to the date of their maturity or redemption, as the case may be, but
excluding, however, the amount of any moneys for the payment of principal of, or
premium, if any, or interest on the Securities of such series (1) theretofore
repaid to the Company in accordance with the provisions of Section 10.04, or (2)
paid to any State or to the District of Columbia pursuant to its unclaimed
property or similar laws, and if in any such case the Company shall also pay or
cause to be paid all other 

                                     61
<PAGE>
<PAGE>

sums payable hereunder by the Company, then (except in the case of (c) above as
to (i) rights of registration of transfer and exchange and any right of the
Company of optional redemption and to deliver Securities of such series to the
Trustee for cancellation, (ii) substitution or mutilated, defaced, destroyed,
lost or stolen Securities, (iii) the rights, obligations and immunities of the
Trustee hereunder and (iv) the rights of the Securityholders as beneficiaries
hereof with respect to the property so deposited with the Trustee, all of which
shall continue in full force and effect) all of the Company's liability with
respect to principal, premium, if any, and interest on the Securities of such
series shall be discharged, this Indenture shall cease to be of further effect
as to such series, and the Trustee, on demand of the Company accompanied by an
Officers' Certificate and an Opinion of Counsel and at the cost and expense of
the Company, shall execute proper instruments acknowledging satisfaction of and
discharging this Indenture as to such series, the Company, however, hereby
agreeing to reimburse the Trustee for any costs or expenses thereafter
reasonably and properly incurred by the Trustee in connection with this
Indenture or the Securities; provided, however, that the rights of
Securityholders to receive amounts in respect of principal of and interest on
the Securities held by them shall not be delayed longer than required by then-
applicable mandatory rules or policies of any securities exchange if the
Securities of such series continue to be listed.  Notwithstanding the foregoing,
if the Company makes a deposit of cash and/or obligations described in clause
(c) above with respect to any series of Securities which, under the terms
specified in the resolution or supplemental indenture or indentures referred to
in Section 2.03, pursuant to which such series is created, is subject to the
provisions of this sentence (whether or not such resolution or supplemental
indenture provides that such series can be discharged prior to maturity under
clause (c) above), and, concurrently with such deposit, notifies the Trustee
that such series shall no longer have the benefit of all or any portion of the
provisions of Article Four, Section 3.05 and Section 3.06 of this Indenture and
such other provisions of this Indenture or the resolution or supplemental
indenture, pursuant to which such series is created, as are specifically
permitted in such resolution or supplemental indenture to be made inapplicable
under this sentence with respect to such series, this Indenture and such
supplemental indenture or resolution shall thereupon be deemed amended with
respect to such series solely by the deletion in their entirety of such
provisions and this Indenture and such supplemental indenture or resolution
shall in all other respects be unaffected thereby.

        SECTION 10.02.  Deposited Moneys to be Held in Trust by Trustee. 
Subject to the provisions of Section 10.04, all moneys and obligations deposited
with the Trustee pursuant to Section 10.01 shall be held in trust and applied by
it to the payment, either directly or through any paying agent (including the
Company if acting its own paying agent), to the holders of the particular
Securities for the payment of which such moneys and obligations have been
deposited with the Trustee, of all sums due and to become due thereon for
principal, premium, if any, and interest, if any; provided, however, that the
Company shall be entitled from time to time to withdraw cash and/or obligations
deposited under clause (c) or the last sentence of Section 10.01 provided that
the cash and obligations thereafter on deposit and after giving effect to such
withdrawal would, if then deposited under such clause, satisfy in all respects
the requirements of such clause or the last sentence of Section 10.01.  At the
time of any such withdrawal, the Company shall deliver to the Trustee an
Officers' Certificate demonstrating compliance with the provisions of such
clause or sentence.

        SECTION 10.03.  Paying Agent to Repay Moneys Held.  Upon the
satisfaction and discharge of this Indenture all moneys then held by any paying
agent of the Securities (other than the Trustee) shall, upon demand of the
Company, be repaid to it or paid to the Trustee, and thereupon such paying agent
shall be released from all further liability with respect to such moneys.

        SECTION 10.04.  Return of Unclaimed Moneys.  Except as may be required
under applicable law, any moneys deposited with or paid to the Trustee or any
paying agent for payment of the principal of, and premium, if any, or interest,
if any, on Securities and not applied but remaining unct as may be required
under applicable law, any moneys deposited with or paid to the Trustee or any
paying agent for payment of the principal of, and premium, if any, or interest,
if any, on Securities and not applied but remaining unclaimed by the holders of
Securities for two years after the date upon which the principal of, and
premium, if any, or interest, if any, on such Securities, as the case may be,
shall have become due and payable, shall be repaid to the Company by the Trustee
or such paying agent on written demand; and the holder of any of the Securities
shall thereafter look only to the Company for any payment which such holder may
be entitled to collect and all liability of the Trustee or such paying agent
with respect to such moneys shall thereupon cease.

                              ARTICLE THIRTEEN.

                  REDEMPTION OF SECURITIES -- MANDATORY AND
                           OPTIONAL SINKING FUND.

        SECTION 13.01.  Applicability of Article.  The provisions of this
Article shall be applicable to the Securities of any series which are redeemable
at the option of the Company before their maturity or to any sinking fund for
the retirement of Securities of a series except as otherwise specified as
contemplated by Section 2.03 for Securities of such series.

        SECTION 13.02.  Notice of Redemption; Selection of Securities.  In case
the Company shall desire to exercise the right to redeem all, or, as the case
may be, any part of the Securities of any series in accordance with their terms,
it shall fix a date for redemption and shall mail a notice 

                                     66
<PAGE>
<PAGE>

of such redemption at least 30 and not more than 60 days prior to the date fixed
for redemption to the holders of Securities of such series so to be redeemed as
a whole or in part at their last addresses as the same appear on the Securities
register.  Such mailing shall be by first class mail.  The notice if mailed in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the holder receives such notice.  In any case, failure to
give such notice by mail or any defect in the notice to the holder of any
Security of a series designated for redemption as a whole or in part shall not
affect the validity of the proceedings for the redemption of any other Security
of such series.

        Each such notice of redemption shall specify the date fixed for
redemption, the redemption price at which Securities of such series are to be
redeemed, the place or places of payment, that payment will be made upon
presentation and surrender of such Securities, that interest accrued to the date
fixed for redemption will be paid as specified in said notice, and that on and
after said date interest thereon or on the portions thereof to be redeemed will
cease to accrue.  If less than all the Securities of such series are to be
redeemed the notice of redemption shall specify the numbers of the Securities of
that series to be redeemed.  In case any Security of a series is to be redeemed
in part only, the notice of redemption shall state the portion of the principal
amount thereof to be redeemed and shall state that on and after the date fixed
for redemption, upon surrender of such Security, a new Security or Securities of
that series in principal amount equal to the unredeemed portion thereof will be
issued.

        On or prior to the redemption date specified in the notice of
redemption given as provided in this Section, the Company will deposit with the
Trustee or with one or more paying agents an amount of money sufficient to
redeem on the redemption date all the Securities so called for redemption at the
appropriate redemption price, together with accrued interest to the date fixed
for redemption.

        If less than all the Securities of a series are to be redeemed the
Company will give the Trustee notice not less than 60 days prior to the
redemption date as to the aggregate principal amount of Securities of that
series to be redeemed and the Trustee shall select, in such manner as in its
sole discretion it shall deem appropriate and fair, the Securities of that
series or portions thereof (in integral multiples of $1,000, except as otherwise
set forth in the applicable form of Security) to be redeemed.

                                     67
<PAGE>
<PAGE>

        SECTION 13.03.  Payment of Securities Called for Redemption.  If notice
of redemption has been given as provided in Section 13.02 or Section 13.04, the
Securities or portions of Securities of the series with respect to which such
notice has been given shall become due and payable on the date and at the place
or places stated in such notice at the applicable redemption price, together
with interest accrued to the date fixed for redemption (unless such date is an
interest payment date, in which case such accrued interest shall be paid to the
holders of record on the relevant record date, and no such accrued interest
shall be paid with the redemption price), and on and after said date (unless the
Company shall default in the payment of such Securities at the redemption price,
together with interest accrued to said date) interest on the Securities or
portions of Securities of any series so called for redemption shall cease to
accrue.  On presentation and surrender of such Securities at a place of payment
specified in said notice, the said Securities or the specified portions thereof
shall be paid and redeemed by the Company at the applicable redemption price,
together with interest accrued thereon to the date fixed for redemption (unless
such date is an interest payment date, in which case such accrued interest shall
be paid to the holders of record on the relevant record date, and no such
accrued interest shall be paid with the redemption price).

        Upon presentation of any Security of any series redeemed in part only,
the Company may execute and the Trustee shall authenticate and deliver to the
holder thereof, at the expense of the Company, a new Security or Securities of
such series of authorized denominations, in principal amount equal to the
unredeemed portion of the Security so presented.

        SECTION 13.04.  Mandatory and Optional Sinking Fund.  The minimum
amount of any sinking fund payment provided for by the terms of Securities of
any series determined pursuant to Section 2.03 is herein referred to as a
"mandatory sinking fund payment", and any payment in excess of such minimum
amount provided for by the terms of Securities of any series is herein referred
to as an "optional sinking fund payment".  The last date on which any such
payment may be made is herein referred to as a "sinking fund payment date".

        In lieu of making all or any part of any mandatory sinking fund payment
with respect to any Securities of a series in cash, the Company may at its
option (a) deliver to the Trustee Securities of that series (other than any
previously called for redemption) theretofore purchased or 

                                     68
<PAGE>
<PAGE>

otherwise acquired by the Company and (b) may apply as a credit Securities of
that series which have been previously delivered to the Trustee by the Company
or Securities of that series which have been redeemed either at the election of
the Company, pursuant to the terms of such Securities or through the application
of optional sinking fund payments pursuant to the next succeeding paragraph, in
each case in satisfaction of all or any part of any mandatory sinking fund
payment, provided that such Securities have not been previously so credited. 
Each such Security so delivered or applied as a credit shall be credited at the
sinking fund redemption price for such Securities and the amount of any
mandatory sinking fund shall be reduced accordingly.  If the Company intends so
to deliver or credit such Securities with respect to any mandatory sinking fund
payment it shall deliver to the Trustee at least 45 days prior to the next
succeeding sinking fund payment date for such series (a) a certificate signed by
the Treasurer or an Assistant Treasurer of the Company specifying the portion of
such sinking fund payment, if any, to be satisfied by payment of cash and the
portion of such sinking fund payment, if any, which is to be satisfied by
delivering and crediting such Securities and (b) any Securities to be so
delivered if not previously delivered.  All Securities so delivered to the
Trustee shall be cancelled by the Trustee and no Securities shall be
authenticated in lieu thereof.  If the Company fails to deliver such certificate
and Securities at or before the time provided above, the Company shall not be
permitted to satisfy any portion of such mandatory sinking fund payment by
delivery or credit of Securities.

        At its option the Company may pay into the sinking fund for the
retirement of Securities of any particular series, on or before each sinking
fund payment date for such series, any additional sum in cash as specified by
the terms of such series of Securities.  If the Company intends to exercise its
right to make any such optional sinking fund payment, it shall deliver to the
Trustee at least 45 days prior to the next succeeding sinking fund payment date
for such Series a certificate signed by the Treasurer or an Assistant Treasurer
of the Company stating that the Company intends to exercise such optional right
and specifying the amount which the Company intends to pay on such sinking fund
payment date.  If the Company fails to deliver such certificate at or before the
time provided above, the Company shall not be permitted to make any optional
sinking fund payment with respect to such sinking fund payment date.  To the
extent that such right is not exercised in any year it shall not be cumulative
or carried forward to any subsequent year.

                                     69
<PAGE>
<PAGE>

        If the sinking fund payment or payments (mandatory or optional) made in
cash plus any unused balance of any preceding sinking fund payments made in cash
shall exceed $50,000 (or a lesser sum if the Company shall so request) with
respect to the Securities of any particular series, it shall be applied by the
Trustee or one or more paying agents on the next succeeding sinking fund payment
date to the redemption of Securities of such series at the sinking fund
redemption price together with accrued interest to the date fixed for
redemption.  The Trustee shall select, in the manner provided in Section 13.02,
for redemption on such sinking fund payment date a sufficient principal amount
of Securities of such series to absorb said cash, as nearly as may be, and the
Trustee shall, at the expense and in the name of the Company, thereupon cause
notice of redemption of Securities of such series to be given in substantially
the manner and with the effect provided in Sections 13.02 and 13.03 for the
redemption of Securities of that series in part at the option of the Company,
except that the notice of redemption shall also state that the Securities of
such series are being redeemed for the sinking fund.  Any sinking fund moneys
not so applied or allocated by the Trustee or any paying agent to the redemption
of Securities of that series shall be added to the next cash sinking fund
payment received by the Trustee or such paying agent and, together with such
payment, shall be applied in accordance with the provision of this Section
13.04.  Any and all sinking fund moneys held by the Trustee or any paying agent
on the maturity date of the securities of any particular series, and not held
for the payment or redemption of particular Securities of such series, shall be
applied by the Trustee or such paying agent, together with other moneys, if
necessary, to be deposited sufficient for the purpose, to the payment of the
principal of the Securities of that series at maturity.

        On or before each sinking fund payment date, the Company shall pay to
the Trustee or to one or more paying agents in cash a sum equal to all interest
accrued to the date fixed for redemption on Securities to be redeemed on the
next following sinking fund payment date pursuant to this Section.

        Neither the Trustee nor any paying agent shall redeem any Securities of
a series with sinking fund moneys, and the Trustee shall not mail any notice of
redemption of Securities of such series by operation of the sinking fund, during
the continuance of a default in payment of interest on such Securities or of any
Event of Default (other than an Event of Default occurring as a consequence of
this paragraph) with respect to such Securities, except that if 

                                     70
<PAGE>
<PAGE>

the notice of redemption of any Securities shall theretofore have been mailed in
accordance with the provisions hereof, the Trustee or any paying agent shall
redeem such Securities if cash sufficient for that purpose shall be deposited
with the Trustee or such paying agent for that purpose in accordance with the
terms of this Article Thirteen.  Except as aforesaid, any moneys in the sinking
fund for such series at the time when any such default or Event of Default shall
occur and any moneys thereafter paid into the sinking fund shall, during the
continuance of such default or Event of Default, be held as security for the
payment of all Securities of such series; provided, however, that in case such
Event of Default or default shall have been cured or waived as provided herein,
such moneys shall thereafter be applied on the next succeeding sinking fund
payment date on which such moneys may be applied pursuant to the provisions of
this Section 13.04.

        The First National Bank of Chicago hereby accepts the trusts in this
Indenture declared and provided, upon the terms and conditions hereinabove set
forth.

      Re:   MascoTech, Inc.
            Registration Statement
            On Form S-3 

Dear Sirs:

      I am acting as your counsel in connection with the Registration Statement

"Subordinated Securities"), shares of Preferred Stock, $1.00 par value (the
"Preferred Shares"), Depositary Shares representing Preferred Stock and shares
of Common Stock, $1.00 par value (the "Common Shares"). The Senior Securities
are to be issued under an Indenture between the Company and The First National
Bank of Chicago, as trustee (the "Senior Indenture") and the Subordinated
Securities are to be issued under an Indenture (as amended by a Supplemental
Indenture) between the Company and The First National Bank of Chicago (as

"Subordinated Indenture"). The Senior Securities and Subordinated Securities are
herein referred to as the "Securities", and the Senior Indenture and
Subordinated Indenture are herein referred to as the "Indentures". The Common
Shares and Preferred Shares are herein referred to as the "Shares".  

     In addition to the Shares, the Registration Statement also registers Common

Shares.

<PAGE>
<PAGE>

      I have examined originals or copies, certified or otherwise identified to
my satisfaction, of such documents and corporate records as I have deemed
necessary or appropriate in connection with this opinion.

      Based upon the foregoing, I am of the opinion that:

      (1)   The Company has been duly incorporated and is a validly existing
corporation in good standing under the laws of the State of Delaware, with
corporate power under such laws to enter into the Indentures and to issue the
Securities, the Shares and the Conversion Shares;

      (2)   The Senior Indenture in the form filed as an Exhibit to the
Registration Statement has been duly authorized by the Company and when executed
and delivered by the Company, it will constitute a valid and legally binding
obligation of the Company;

      (3)   The Subordinated Indenture has been duly authorized, executed and
delivered by the Company and constitutes a valid and legally binding obligation
of the Company;

      (4)   When the issuance of the Securities has been duly authorized by
appropriate corporate action and such Securities have been duly executed,
authenticated and delivered in substantially the forms filed as an Exhibit to
the Registration Statement and in accordance with the Indentures and sold as
described in the Registration Statement, including the Prospectuses and
Prospectus Supplements relating to such Securities, subject to the final terms
of the Securities being in compliance with then applicable law, the Securities
will be legal, valid and binding obligations of the Company entitled to the
benefits of the Indentures; 

      (5)   When the issuance of the Shares has been duly authorized by
appropriate corporate action and the Shares have been duly issued and sold as
described in the Registration Statement, including the Prospectuses and
Prospectus Supplements relating to the Shares, the Shares will be legally
issued, fully paid and nonassessable; and

      (6)   When the issuance of the Conversion Shares issuable upon conversion
of convertible Subordinated Securities or convertible Preferred Shares has been
duly authorized by appropriate corporate action and when the Conversion Shares
have been issued upon conversion  pursuant to the Indenture or the Certificate
of Designation creating such securities and as described in the Registration
Statement, including the Prospectuses and Prospectus Supplements relating to
such convertible Subordinated Securities or convertible Preferred Shares, the
Conversion Shares will be legally issued, fully paid and nonassessable.

      I hereby consent to the filing of this opinion as Exhibit 5 to the
Company's Registration Statement.  I also consent to the reference to me under
the caption "Legal Opinions" in the Prospectuses.

                                    Very truly yours,
