                           DESCRIPTION OF DEBENTURES
 
  The 7 1/4% Debentures due 2025 (the "Debentures") offered hereby are a series
of "Securities" as defined and described in the accompanying Prospectus dated
December 13, 1995 (the "Prospectus"), and the following description of terms of
the Debentures supplements the description of the general terms and provisions
of the Securities set forth in the Prospectus.
 
  The Debentures are to be issued pursuant to the provisions of an Indenture
dated as of March 15, 1988, between the Company and The Chase Manhattan Bank
(National Association), as Trustee (hereinafter called the "Trustee"), as
supplemented by supplemental indentures (such Indenture as supplemented and
amended from time to time in accordance with the terms thereof being
hereinafter referred to as the "Indenture").
 
  The Debentures will mature on December 15, 2025. The Debentures are to bear
interest from December 15, 1995 (at the rate per annum referred to on the cover
of this Prospectus Supplement) payable on June 15 and December 15 of each year
at the office of the Trustee in The City of New York, commencing on June 15,
1996. Subject to certain exceptions therein set forth, the Indenture provides
for the payment of interest on any interest payment date only to holders of the
Debentures in whose names the Debentures are registered on the interest record
date, which is the May 31 or November 30, as the case may be, next preceding
such interest payment date if such date is a business day or the business day
immediately preceding such date if such date is not a business day.
 
  The Debentures will not be redeemable prior to maturity.
 
GLOBAL SECURITIES
 
  The Debentures will be issued in the form of one or more Global Securities
that will be deposited with, or on behalf of, The Depository Trust Company, New
York, New York (the "Depositary"). Unless and until it is exchanged in whole or
in part for Securities in definitive form, a Global Security may not be
transferred except as a whole to a nominee of the Depositary for such Global
Security, 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.
 
BOOK-ENTRY SYSTEM
 
  Initially, the Debentures will be registered in the name of Cede & Co., the
nominee of the Depositary. Accordingly, beneficial interests in the Debentures
will be shown on, and transfers thereof will be effected only through, records
maintained by the Depositary and its participants.
 
  The Depositary has advised the Company and the Underwriters as follows: the
Depositary is a limited-purpose trust company organized under the New York
Banking Law, a "banking organization" within the meaning of the New York
Banking Law, a member of the United States Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
United States Securities Exchange Act of 1934, as amended. The Depositary holds
securities that its participants ("Direct Participants") deposit with the
Depositary. The Depositary also facilitates the settlement among Direct
Participants of securities transactions, such as transfers and pledges, in
deposited securities through electronic computerized book-entry changes in such
Direct Participants' accounts, thereby eliminating the need for physical
movement of securities certificates. Direct Participants include securities
brokers and dealers (including the Underwriters), banks, trust companies,
clearing corporations, and certain other organizations. The Depositary is owned
by a number of its Direct Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc. and the National Association of
Securities Dealers, Inc. Access to the Depositary's book-entry system is also
available to others such as securities brokers and dealers, banks and trust
companies that clear through or maintain a custodial relationship with a Direct
Participant, either directly or indirectly ("Indirect Participants"). The rules
applicable to the Depositary and its Direct and Indirect Participants are on
file with the United States Securities and Exchange Commission.
 
                                      S-3

 
  The Depositary advises that its established procedures provide that (i) upon
issuance of the Debentures by the Company, the Depositary will credit the
accounts of Participants designated by the Underwriters with the principal
amounts of the Debentures purchased by the Underwriters and (ii) ownership of
interests in the Global Securities will be shown on, and the transfer of the
ownership will be effected only through, records maintained by the Depositary,
the Direct Participants and the Indirect Participants. The laws of some states
require that certain persons take physical delivery in definitive form of
securities which they own. Consequently, the ability to transfer beneficial
interests in the Global Securities is limited to such extent.
 
  So long as a nominee of the Depositary is the registered owner of the Global
Securities, such nominee for all purposes will be considered the sole owner or
holder of such Global Securities under the Indenture. Except as provided below,
owners of beneficial interests in the Global Securities will not be entitled to
have Debentures registered in their names, will not receive or be entitled to
receive physical delivery of Debentures in definitive form and will not be
considered the owners or holders thereof under the Indenture.
 
  Neither the Company, the Trustee, any paying agent nor the registrar will
have any responsibility or liability for any aspect of the records relating to
or payments made on account of beneficial ownership interests in the Global
Securities, or for maintaining, supervising or reviewing any records relating
to such beneficial ownership interests.
 
  Principal and interest payments on the Debentures registered in the name of
the Depositary's nominee will be made in immediately available funds to the
Depositary's nominee as the registered owner of the Global Securities. Under
the terms of the Debentures, the Company and the Trustee will treat the persons
in whose names the Debentures are registered as the owners of such Debentures
for the purpose of receiving payment of principal and interest on such
Debentures and for all other purposes whatsoever. Therefore, neither the
Company, the Trustee nor any paying agent has any direct responsibility or
liability for the payment of principal or interest on the Debentures to owners
of beneficial interests in the Global Securities. The Depositary has advised
the Company and the Trustee that its current practice is, upon receipt of any
payment of principal or interest, to credit Direct Participants' accounts on
the payment date in accordance with their respective holdings of beneficial
interests in the Global Securities as shown on the Depositary's records, unless
the Depositary has reason to believe that it will not receive payment on the
payment date. Payments by Direct and Indirect Participants to owners of
beneficial interests in the Global Securities will be governed by standing
instructions and customary practices, as is 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 Direct and Indirect Participants and not of
the Depositary, the Trustee, or the Company, subject to any statutory
requirements that may be in effect from time to time. Payment of principal and
interest to the Depositary is the responsibility of the Company or the Trustee,
disbursement of such payments to the owners of beneficial interests in the
Global Securities shall be the responsibility of the Depositary and Direct and
Indirect Participants.
 
  Debentures represented by a Global Security will be exchangeable for
Debentures in definitive form of like tenor as such Global Security in
denominations of $1,000 and in any greater amount that is an integral multiple
if the Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for such Global Security or if at any time the
Depositary ceases to be a clearing agency registered under applicable law and a
successor depositary is not appointed by the Company within 90 days or the
Company in its discretion at any time determines not to require all of the
Debentures to be represented by a Global Security and notifies the Trustee
thereof. Any Debentures that are exchangeable pursuant to the preceding
sentence are exchangeable for Debentures issuable in authorized denominations
and registered in such names as the Depositary shall direct. Subject to the
foregoing, a Global Security is not exchangeable, except for a Global Security
or Global Securities of the same aggregate denominations to be registered in
the name of the Depositary or its nominee.
 
                                      S-4

 
SAME-DAY SETTLEMENT AND PAYMENT
 
  Settlement for the Debentures will be made by the Underwriters in immediately
available funds. So long as the Depositary continues to make its Same-Day Funds
Settlement System available to the Company, all payments of principal and
interest on the Debentures will be made by the Company in immediately available
funds.
 
  Secondary trading in long-term notes and debentures of corporate issuers is
generally settled in clearing-house or next-day funds. In contrast, the
Debentures will trade in the Depositary's Same-Day Funds Settlement System
until maturity, and secondary market trading activity in the Debentures will
therefore be required by the Depositary to settle in immediately available
funds. No assurance can be given as to the effect, if any, of settlement in
immediately available funds on trading activity in the Debentures.

                                  UNDERWRITERS
 
  Under the terms and subject to the conditions contained in an Underwriting
Agreement dated the date hereof, the Underwriters named below have severally

principal amounts of Debentures set forth below.
 


                                                                     PRINCIPAL

  The nature of the Underwriters' obligation is such that they are committed to
take and pay for all of the Debentures if any are taken.
 
  The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the Debentures are subject to,
among other things, the approval of certain legal matters by their counsel and
to the conditions that no stop order suspending the effectiveness of the
Registration Statement is in effect and no proceedings for such purpose are
pending before or threatened by the Securities and Exchange Commission and that
there has been no material adverse change (not in the ordinary course of
business) in the condition of the Company and its subsidiaries taken as a whole
from that set forth in or contemplated by the Registration Statement.
 
  The Underwriters propose to offer part of the Debentures directly to the
public at the public offering price set forth on the cover page hereof and part
to dealers at a price which represents a concession, not in excess of .50% of
the principal amount under the public offering price of the Debentures. Any
Underwriter may allow and such dealers may reallow a concession, not in excess
of .25% of the principal amount of the Debentures, to certain other dealers.
After the initial offering of the Debentures, the public offering price of the
Debentures and such concessions may be changed.
 
  The Company has agreed to indemnify the several Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, as
amended.
 
  The Company has agreed not to offer, sell, contract to sell or otherwise
dispose of any of its debt securities substantially similar to the Debentures
during the period beginning on the date of this Prospectus Supplement and
continuing to and including the date the Debentures are delivered to the
Underwriters, without the prior written consent of Morgan Stanley & Co.
Incorporated.
 
  In the ordinary course of their respective businesses, the Underwriters or
affiliates of the Underwriters have engaged and may in the future engage in
commercial banking or investment banking transactions with the Company. William
L. Weiss, a director of the Company, is also a director of Merrill Lynch & Co.,
Inc., an affiliate of one of the Underwriters.

                                  TENNECO INC.
 
  Tenneco Inc. (the "Company") directly, through agents designated from time to
time, or through dealers or underwriters also to be designated, may sell from
time to time up to $1,000,000,000 aggregate principal amount (or its
equivalent) of its debt securities (the "Securities") on terms to be determined
at the time of sale. The specific designation, aggregate principal amount,
maturities, rate (or method of calculation) and time of payment of interest,
purchase price, any terms for redemption and the agent, dealer or underwriter,
if any, in connection with the sale of the Securities in respect of which this
Prospectus is being delivered and other terms of the Securities are set forth
in the accompanying Prospectus Supplement (the "Prospectus Supplement"). The
Company reserves the sole right to accept and, together with its agents from
time to time, to reject in whole or in part any proposed purchase of Securities
to be made directly or through agents.
 
  If an agent of the Company or a dealer or underwriter is involved in the sale
of the Securities in respect of which this Prospectus is being delivered, the
agent's commission, dealer's purchase price, or underwriter's discount is set
forth in, or may be calculated from, the Prospectus Supplement, and the net
proceeds to the Company from such sale will be the purchase price of such
Securities less such commission in the case of an agent, the purchase price of
such Securities in the case of a dealer or the public offering price less such
discount in the case of an underwriter, and less, in each case, the other
attributable issuance expenses. The aggregate proceeds to the Company from all
the Securities will be the purchase price of Securities sold less the aggregate
of agents' commissions and underwriters' discounts and other expenses of
issuance and distribution. See "Plan of Distribution" for possible
indemnification arrangements for the agents, dealers and underwriters.
 
                               ----------------

                           DESCRIPTION OF SECURITIES
 
  The Securities are to be issued pursuant to the provisions of an indenture
(hereinafter called the "Indenture") dated as of March 15, 1988, between the
Company and The Chase Manhattan Bank (National Association), as Trustee
(hereinafter called the "Trustee"). The following statements are summaries of
certain provisions contained in the Indenture, a copy of which is filed as an
exhibit to the registration statement of which this Prospectus is a part. They
do not purport to be complete statements of all the terms and provisions of the
Indenture, and reference is made to the Indenture for full and complete
statements of such terms and provisions.
 
GENERAL
 
  The Indenture does not limit the amount of securities that can be issued
thereunder, nor does it restrict the payment of dividends or the acquisition of
capital stock by the Company or any subsidiary of the Company or the amount of
debt which the Company or any subsidiary of the Company can incur. Additional
securities may be issued under the Indenture from time to time and offered on
terms determined by market conditions at the time of sale.
 
  The Securities will be unsecured and will rank equally and ratably with other
unsecured and unsubordinated debt of the Company.
 
  The Prospectus Supplement sets forth the following terms of the Securities in
respect of which this Prospectus is delivered: (i) the designation of such
Securities, (ii) the aggregate principal amount of such Securities, (iii) the
percentage of principal amount at which such Securities will be issued, (iv)
the date or dates on which such Securities will mature, (v) the rate or rates,
if any, per annum (which may be fixed or variable) at which such Securities
will bear interest or the method of determining such rate or rates, (vi) the
times at which such interest, if any, will be payable, (vii) the date, if any,
after which such Securities may be redeemed, or any applicable sinking fund
requirements, and the redemption price or prices, (viii) the currency in which
the Securities will be denominated (if other than U.S. dollars), and (ix) any
other special terms.
 
                                       3

 
  Principal, premium, if any, and interest, if any, will be payable at the
principal corporate trust office of the Trustee in The City of New York, or
that of its agent, provided that payment of interest, other than interest
payable at maturity or upon redemption, may be made at the option of the
Company by check mailed to the address of the person entitled thereto as it
appears on registry books of the Company. Unless otherwise indicated in the
Prospectus Supplement, payment of interest on any interest payment date will be
made only to holders of the Securities in whose names the Securities are
registered on the record date specified in the Securities.
 
  The Securities will be in registered form, without coupons, issuable in
denominations of $1,000 (unless otherwise specified in the Prospectus
Supplement) or any authorized multiple thereof.
 
LIENS
 
  So long as any Securities are outstanding, neither the Company nor any
Subsidiary (as defined below) will create, assume or suffer to exist any Lien
(as defined below) which secures Debt (as defined below) and which is on any
capital stock of any Subsidiary owned by it; provided, however, that this
prohibition does not apply to or prevent the creation or existence of any Lien
upon any capital stock (i) created at the time of the acquisition of such
capital stock by the Company or any Subsidiary or within one year after such
time to secure all or a portion of the purchase price for such capital stock or
Debt incurred to finance such purchase price; (ii) held by a person existing on
such capital stock at the time such person becomes a Subsidiary; or (iii) of a
foreign Subsidiary held directly or indirectly by another foreign Subsidiary to
secure Debt of such other foreign Subsidiary.
 
  The Indenture provides that so long as any Securities are outstanding, the
Company will not, and will not permit any Subsidiary, other than a Finance
Subsidiary (as defined below) to, pledge, mortgage or hypothecate, or permit
any Lien upon, any property or assets at any time owned by the Company or any
Subsidiary, other than a Finance Subsidiary, to secure any Debt, without making
effective provision whereby the Securities shall (so long as such other Debt
shall be so secured) be equally and ratably secured with any and all such Debt
and with any other Debt similarly entitled to be equally and ratably secured;
provided, however, that such restriction shall not apply to nor prevent the
creation or existence of any encumbrance upon capital stock permitted under the
provision described in the preceding paragraph or:
 
    (a) any Lien upon any property or assets of the Company or any Subsidiary
  in existence on March 15, 1988, or created pursuant to an "after-acquired
  property" clause or similar term (including any Liens created upon

  price for such property or assets or Debt incurred to finance such purchase
  price;

  the time such person becomes a Subsidiary by acquisition or otherwise;

    (f) any extension, renewal or refunding of any permitted Liens on capital
  stock or any Lien permitted by paragraphs (a), (b), (c), (d) or (e) above
  on substantially the same property or assets theretofore subject thereto or
  any part thereof, securing Debt not in excess of the amount outstanding on
  the date of such extension, renewal or refunding;
 
                                       4

    (m) the right reserved to, or vested in, any municipality or public
  authority by the terms of any right, power, franchise, grant, license,
  permit or by any provision of law, to purchase or recapture or to designate
  a purchaser of, any property;
 
    (n) Liens of taxes and assessments which are (i) for the then current

  a Lien upon such property or assets permitted by paragraphs (a) through (v)
  inclusive; or
 
    (v) any Lien securing any Debt in an amount which, together with all
  other Debt secured by a Lien that is not otherwise permitted by the
  provisions of any other provision set forth above, does not at the time of
  the incurrence of the Debt so secured exceed 10% of Consolidated Net
  Tangible Assets (as defined below), as shown on a balance sheet as of the

                                       5

 
  If the Company or any of its Subsidiaries (other than a Finance Subsidiary)
shall propose to so pledge, mortgage or hypothecate any assets or property at
any time owned by it to secure any Debt, other than as permitted by
subdivisions (a) through (v) inclusive above, the Company will prior thereto
give written notice thereof to the Trustee, and the Company will prior to or
simultaneously with such pledge, mortgage or hypothecation, by supplemental
indenture executed to the Trustee (or to the extent legally necessary to an
additional or separate trustee), in form satisfactory to the Trustee, cause all
the Securities effectively to be secured equally and ratably with such Debt,
pledge, mortgage or hypothecation of such assets or property.
 
MODIFICATION OF INDENTURE
 
  The Indenture provides that, with the consent of the holders of not less than
a majority in principal amount of Securities of all series at the time
outstanding which will be affected by the modification or amendment to the
Indenture (voting as a single class), the Company and the Trustee may enter
into supplemental indentures for the purposes of modifying or amending any of
the provisions of the Indenture or of any supplemental indenture, or of
modifying the rights of the holders of the Securities affected by such
modification or amendment, but may not, without the consent of the holders of
all outstanding Securities affected by such modification or amendment, (i)
extend the maturity, reduce the interest rate or modify in any other way the
terms of payment of principal, premium, if any, or interest upon the
Securities, or (ii) reduce the aforesaid percentage of Securities, the holders
of which are required to consent to any such supplemental indenture.
 
DEFAULTS AND RIGHTS UPON DEFAULT
 
  The Indenture defines the term "default" with respect to a series of
Securities to mean a default in the payment of interest or the making of any
sinking fund redemption for 30 days on such series, a default in the payment of
principal of or premium, if any, on such series (other than failure to make a
sinking fund redemption), and a default in the performance of any of the
Company's covenants in the Indenture for 60 days after written notice of such
default.
 
  The term "default" also includes certain events involving the Company or
Tennessee Gas Pipeline Company, a wholly-owned subsidiary of the Company
("Tennessee"), but not any of the Company's other Subsidiaries, in bankruptcy,
reorganization, receivership or other insolvency proceedings, or an assignment
by the Company or Tennessee for the benefit of creditors; provided that at the
time of such event Tennessee is a Subsidiary of the Company. The assets of
Tennessee presently consist primarily of its interstate gas pipeline system,
assets utilized in its automotive business and capital stock, held directly or
indirectly, of substantially all of the other Subsidiaries of the Company. The
Indenture contains no restriction upon the transfer, sale or other disposition
by Tennessee of all or a portion of its assets, whether to the Company or to
unaffiliated parties, nor does it require that Tennessee's corporate existence
continue.
 
  In addition, the term "default" includes default by the Company in the
payment of principal of or interest on any obligation for money borrowed beyond
any period of grace specified therefor or default by the Company in the
performance of any of the terms of any agreement under which such obligation is
created if the effect is to cause such obligation to become due prior to its
stated maturity, if any such default is not waived by the required percentage
of the holders of such obligations. In addition, the term "default" includes
any default, of the type described in the preceding sentence, (i) by a domestic
Subsidiary (other than a Finance Subsidiary) if such default results in
acceleration of Debt of that Subsidiary in excess of 1% of the consolidated
Debt of the Company and its Subsidiaries (excluding Debt of Finance
Subsidiaries) or (ii) by two or more domestic Subsidiaries (other than a
Finance Subsidiary) if such default results in acceleration of Debt of those
Subsidiaries in excess of 5% of the consolidated Debt of the Company and its
Subsidiaries (excluding Debt of Finance Subsidiaries).
 
  On or before May 1 in each year, the Company must file with the Trustee an
officers' certificate stating whether or not, to the knowledge of the signers,
the Company is in default in the performance of any of the terms of the
Indenture.
 
                                       6

 
  If a default shall have occurred and be continuing with respect to (i) the
payment of principal of, premium, if any, or interest or sinking fund
redemption payment on, any series of Securities or (ii) the performance of any
other covenant of the Company relating to that series of Securities, the
Trustee or the holders of at least 25% in principal amount of the Securities of
the series affected in the case of clause (i) (or 25% in principal amount of
all series affected in the case of clause (ii), treated as a single class) then
outstanding may declare the principal of all the Securities of such series (or
all such series, as the case may be) to be due and payable, but the holders of
a majority in principal amount of the Securities then outstanding of that
series (or all such series treated as a single class, as the case may be) may
rescind such declaration if the default is cured. No Securityholder may enforce
the Indenture except in the case of a refusal or neglect of the Trustee to act
for 30 days after notice of default and after request by the holders of a
majority in principal amount of the outstanding Securities of any series as to
which a default has occurred in the case of a payment default and all other
series affected thereby in the case of any other default, and the offer to the
Trustee of indemnity and security satisfactory to it, but this provision does
not prevent any Securityholder of that series from enforcing payment of
principal of, or premium, if any, or interest or sinking fund redemption
payment on, his Security. Holders of a majority in principal amount of the
Securities of any and all series affected (treated as a single class) and then
outstanding may direct the Trustee as to proceedings available to it under the
Indenture. Prior to declaration of acceleration, any past non-payment default
with respect to a particular series of Securities may be waived by the holders
of a majority in principal amount of the Securities of all series then
outstanding affected thereby (treated as a single class).
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
  The Indenture provides that the Company will not consolidate with or merge
into, or sell, lease, transfer or otherwise dispose of its assets as, or
substantially as, an entirety to any person unless the person resulting from
such consolidation or into which the Company is merged or which acquired or
leased the assets of the Company as, or substantially as, an entirety assumes
the obligations of the Company under all the Securities then outstanding and,
in the case of any such merger or consolidation, unless the person resulting
from such consolidation or into which the Company is merged is a corporation
existing under the laws of the United States, one of the States thereof or the
District of Columbia.
 
DEFEASANCE
 
 Defeasance and Discharge of Securities of any Series
 
  The Company has the right at any time to be discharged from its obligations
under the Securities of any series (except for certain obligations to register
the transfer or exchange of the Securities of such series, to replace stolen,
lost or mutilated Securities of such series, to maintain paying agencies and
hold monies for payment in trust), subject to certain conditions, by depositing
in trust with the Trustee an amount, in cash or securities of the United States
government or securities issued by government agencies backed by the full faith
and credit of such government ("U.S. Government Obligations"), sufficient to
pay or provide for payment of all principal and interest and premium, if any,
due and to become due on the Securities of such series and paying all other
sums payable by it under the Indenture with respect to the Securities of such
series.
 
  In order to be so discharged of its obligations, the Company must first
deliver to the Trustee either a ruling from the Internal Revenue Service or an
opinion of counsel to the effect that any such satisfaction and discharge will
not result in recognition by holders of the Securities of such series of
income, gain or loss for federal income tax purposes (other than income, gain
or loss that would have been recognized in the same amount and in the same
manner and at the same time or times as would have been the case absent such
satisfaction and discharge). Notwithstanding the foregoing, the obligation of
the Company to pay when due the principal of, any premium, if any, and interest
on the Securities of such series will be reinstated if the Trustee is unable to
pay when due any such amount from the money or U.S. Government Obligations as a
result of any legal proceeding or order of any court or governmental authority.
 
                                       7

 
 Defeasance of Certain Covenants
 
  The Company also has the right to be discharged of its covenant under the
Indenture described under "Liens" above, insofar as the Securities of such
series are concerned, by depositing in trust with the Trustee an amount, in
cash or U.S. Government Obligations, sufficient to pay or provide for payment
of all principal and interest and premium, if any, due and to become due on the
Securities of such series and paying all other sums payable by it under the
Indenture with respect to the Securities of such series. The Company is not
required to deliver any ruling of the Internal Revenue Service or opinion of
counsel with respect to the federal income tax consequences of any such
discharge as described above under the caption "Defeasance and Discharge of
Securities of any Series".
