                                 TENNECO INC.


                      7 5/8 DEBENTURE DUE JUNE 15, 2017


        This Debenture is one of a duly authorized issue of Debentures of the
Company known as its 7 5/8% Debentures due June 15, 2017 (herein called the
"Debentures"), limited to the aggregate principal amount of $300,000,000, all
issued under and equally entitled to the benefits of an Indenture (herein,
together with any amendments and supplements thereto, including without
limitation the form and terms of Securities issued pursuant thereto, called the
"Indenture"), dated as of November 1, 1996, executed by the Company to The
Chase Manhattan Bank (herein, together with any successor thereto, called the
"Trustee"), as Trustee, to which Indenture reference is hereby made for a
statement of the rights thereunder of the Trustee and of the registered holders
of the Debentures and of the duties thereunder of the Trustee and the Company.

        The Debentures will be redeemable as a whole or in part, at the option
of the Company at any time, at a redemption price equal to the greater of (i)
100% of their principal amount and (ii) the sum of the present values of the
remaining scheduled payments of principal and interest thereon discounted to the
date of redemption on a semiannual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Treasury Yield plus 20 basis points, plus
accrued interest to the date of redemption.

        "Treasury Yield" means, with respect to any redemption date, the rate
per annum equal to the semiannual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date.

        "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Debentures that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining
term of the Debentures.  "Independent Investment Banker" means Credit Suisse
First Boston Corporation or, if such firm is unwilling or unable to select the
Comparable Treasury Issue, an independent investment banking institution of
national standing appointed by the Trustee.

        "Comparable Treasury Price" means, with respect to any redemption
date, (i) the average of the Reference Treasury Dealer Quotations for such
redemption date, after excluding the highest and lowest such

   5

                                       4

Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than
four such Reference Treasury Dealer Quotations, the average of all such
Quotations.  "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined
by the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third business day preceding such redemption date.

        "Reference Treasury Dealer" means each of Credit Suisse First Boston
Corporation, Morgan Stanley & Co. Incorporated, Citicorp Securities, Inc. and
UBS Securities LLC; provided however, that if any of the foregoing shall cease
to be a primary U.S. Government securities dealer in New York City (a "Primary
Treasury Dealer"), the Company shall substitute therefor another Primary
Treasury dealer.

        Holders of Debentures to be redeemed will receive notice thereof by
first-class mail at least 30 and not more than 60 days prior to the date fixed
for redemption.

        The Indenture permits the Company to issue unsecured debentures, notes,
and/or other evidences of indebtedness in one or more series ("Securities") up
to such principal amount or amounts as may be authorized in accordance with the
terms of the Indenture.

        To the extent permitted by, and as provided in, the Indenture,
modifications or alterations of the Indenture and of the rights and obligations
of the Company and of the holders of the Debentures may be made with the
consent of the Company and with the consent of the holders of not less than a
majority in principal amount of the Securities of all series then outstanding
under the Indenture (treated as a single class) which are affected by the
modification or amendment thereto; provided, however, that without the consent
of the holder hereof no such modification or alteration shall be made which
will affect the terms of payment of the principal of or interest on this 
Debenture.

        In case a default, as defined in the Indenture, shall occur, the
principal of all the Debentures at any such time outstanding under the
Indenture may be declared or may become due and payable, upon the conditions
and in the manner and with the effect provided in the Indenture.  The Indenture
provides that such declaration may in certain events be waived by the holders
of a majority in principal amount of the Debentures outstanding in the case of
payment defaults on the Debentures and in certain other events by the holders
of a majority in principal amount of the Securities of all series then 
outstanding under the Indenture (treated as a single class) which are affected
thereby.

        The Indenture provides that no holder of any Debenture may enforce any
remedy under the Indenture except in the case of refusal or neglect of the
Trustee to act after notice of default and after request by the holders of a
majority in principal amount of the outstanding Debentures in certain events
(and in certain other events by the holders of a majority in principal amount
of the Securities of all series then outstanding under the Indenture, treated
as a single class, which are affected thereby) and the offer to the Trustee of
security and indemnity satisfactory to it; provided, however, that such
provision shall not prevent the holder hereof from enforcing payment of the
principal of or interest on this Debenture.

        Unless this certificate is presented by an authorized representative of
a Depositary to the Issuer or its agent for registration of transfer, exchange
or payment, and any certificate issued is registered in the name of the nominee
of such Depositary or such other name as requested by an authorized
representative of such Depositary and any payment is made to the nominee of
such Depositary, ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL since the registered owner hereof,
the nominee, has an interest herein.

        The Company, the Trustee, any paying agent and any Registrar of the
Debentures may deem and treat the person in whose name this Debenture is
registered as the absolute owner hereof for all purposes whatsoever, and
neither the Company nor the Trustee nor any paying agent nor any Registrar of
the Debentures shall be affected by any notice to the contrary.

                                       5



        No recourse shall be had for the payment of the principal of or the
interest on, this Debenture, or for any claim based hereon or on the Indenture,
against any incorporator or against any stockholder, director or officer, as
such, past, present or future, of the Company, or of any predecessor or
successor corporation, either directly or through the Company or any such
predecessor or successor corporation, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment or penalty or
otherwise, all such liability, whether at common law, in equity, by any
constitution, statute or otherwise, of incorporators, stockholders, directors
or officers being released by every owner hereof by the acceptance of this
Debenture and as part of the consideration for the issue hereof, and being
likewise released by the terms of the Indenture; provided, however, that
nothing herein or in the Indenture contained shall be taken to prevent recourse
to and the enforcement of the liability, if any, of any stockholder or
subscriber to capital stock of the Company upon or in respect of shares of
capital stock not fully paid up.

        All terms used in this Debenture which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.
