     The Underwriters will pay for such Debentures upon delivery thereof at the
office of Credit Suisse First Boston Corporation, New York, N.Y. at 9:00 A.M.,
New York time, on June 16, 1997, or at such other time, not later than June 23,
1997, as shall be designated by the Manager. Payment will be made in immediately
available funds to an account designated by the Company.
 
     The Debentures will have the following terms:
 
     Maturity: June 15, 2017
 
     Interest Rate: 7 5/8%
 
     Redemption provisions: As set forth in the Prospectus.

     We have advised you that we propose to make a public offering of the
Debentures as soon as in our judgment is advisable. We further advise you that
the Debentures are to be offered to the public initially at 99.908% of the
principal amount thereof (i.e., the public offering price) (together with
accrued interest, if any, from June 16, 1997, to the date of payment and
delivery) and to certain dealers selected by us at a price which represents a
concession not in excess of 0.50% of the principal amount thereof under the
public offering price, and that we may allow, and such dealers may reallow, a
concession, not in excess of 0.25% of the principal amount thereof, to certain
other dealers.
 
     Unless otherwise expressly provided herein, all the provisions contained in
the document entitled Tenneco Inc. Underwriting Agreement Standard Provisions
(Debentures) dated April 4, 1997 (the "Base Underwriting Agreement"), a copy of
which we have previously received, are herein incorporated by reference
   2
 
in their entirety and shall be deemed to be a part of this Agreement to the same
extent as if such provisions had been set forth in full herein. The term
"Registration Statement" as used in the Underwriting Agreement shall be deemed
to include the registration statement covering the Debentures (including the
material, if any, incorporated by reference therein), and the terms "Basic
Prospectus" and "Prospectus" shall as so used be modified accordingly. All
capitalized terms used but not otherwise defined herein shall have the meanings
ascribed to them in the Base Underwriting Agreement.
 
     In addition to the representations and warranties contained in the Base
Underwriting Agreement, Tenneco represents and warrants to the Underwriters as
follows (and the certificate to be delivered to the Underwriters pursuant to
Section V of the Base Underwriting Agreement shall certify that the following
representations and warranties are true and correct as of the Closing Date):
 
          (i) Since the respective dates as of which information is given or
     incorporated in the Registration Statement and the Prospectus, except as
     otherwise stated therein, (A) there has been no material adverse change in
     the condition, financial or otherwise, or in the earnings, business affairs
     or business prospects of the Company and the Subsidiaries considered as one
     enterprise, whether or not arising in the ordinary course of business, (B)
     there have been no transactions entered into by the Company or any of the
     Subsidiaries, other than those in the ordinary course of business, which
     are material with respect to the Company and the Subsidiaries considered as
     one enterprise, and (C) except for regular quarterly dividends on the
     common stock of the Company in amounts per share that are consistent with
     past practice, there has been no dividend or distribution of any kind
     declared, paid or made by the Company on any class of its capital stock.
 
          (ii) Neither the Company nor any of the Subsidiaries is in violation
     of its charter or by-laws or in default in the performance or observance of
     any obligation, agreement, covenant or condition contained in any contract,
     indenture, mortgage, deed of trust, loan or credit agreement, note, lease
     or other agreement or instrument to which the Company or any of the
     Subsidiaries is a party or by which it or any of them may be bound, or to
     which any of the property or assets of the Company or any Subsidiary is
     subject (collectively, "Agreements and Instruments") except for such
     defaults that would not result in a Material Adverse Effect; and the
     execution, delivery and performance of this Agreement, the supplemental
     indenture governing the Debentures and the consummation of the transactions
     contemplated herein and in the Registration Statement (including the
     issuance and sale of the Debentures and compliance by the Company with its
     obligations hereunder and under the Indenture (as supplemented) and the
     Debentures) have been duly authorized by all necessary corporate action and
     do not and will not, whether with or without the giving of notice or
     passage of time or both, conflict with or constitute a breach of, or
     default or Repayment Event (as defined below) under, or result in the
     creation or imposition of any lien, charge or encumbrance upon any property
     or assets of the Company or any Subsidiary pursuant to, the Agreements and
     Instruments (except for such conflicts, breaches or defaults or liens,
     charges or encumbrances that would not result in a Material Adverse
     Effect), nor will such action result in any violation of the provisions of
     the charter or by-laws of the Company or any Subsidiary or any applicable
     law, statute, rule regulation, judgment, order, writ or decree of any
     government, instrumentality or court, domestic or foreign, having
     jurisdiction over the Company or any Subsidiary or any of their assets,
     properties, or operations. As used herein, a "Repayment Event" means any
     event or condition which gives the holder of any note, debenture or other
     evidence of indebtedness (or any person acting on such holder's behalf) the
     right to require the repurchase, redemption or repayment of all or a
     portion of such indebtedness by the Company or any Subsidiary, except for
     rights which would not, individually or in the aggregate, have a Material
     Adverse Effect.
 
          (iii) There is no action, suit, proceeding, inquiry or investigation
     before or brought by any court or governmental agency or body, domestic or
     foreign, now pending, or, to the knowledge of the Company, threatened,
     against or affecting the Company or any Subsidiary, which is required to be
     disclosed in the Registration Statement (other than as disclosed therein),
     or which might reasonably be expected to result in a Material Adverse
     Effect, or which might reasonably be expected to materially and adversely
     affect the properties or assets of the Company and the Subsidiaries taken
     as a whole or the consummation of the transactions contemplated in this
     Agreement or the performance by the Company of its obligations
 
                                        2
   3
 
     hereunder, the aggregate of all pending legal or governmental proceedings
     to which the Company or any Subsidiary is a party or of which any of their
     respective property or assets is the subject which are not described in the
     Registration Statement, including ordinary routine litigation incidental to
     the business of the Company and the Subsidiaries, could not reasonably be
     expected to result in a Material Adverse Effect.
 
          (iv) Except as described in the Registration Statement and except as
     would not, singly or in the aggregate, result in a Material Adverse Effect,
     (A) neither the Company nor any of the Subsidiaries is in violation of any
     federal, state, local or foreign statute, law, rule, regulation, ordinance,
     code, policy or rule of common law or any judicial or administrative
     interpretation thereof, including any judicial or administrative order,
     consent, decree or judgment, relating to pollution or protection of human
     health, the environment (including, without limitation, ambient air,
     surface water, groundwater, land surface or subsurface strata) or wildlife,
     including, without limitation, laws and regulations relating to the release
     or threatened release of chemicals, pollutants, contaminants, wastes, toxic
     substance, hazardous substances, petroleum or petroleum products
     (collectively, "Hazardous Materials") or to the manufacture, processing,
     distribution, use, treatment, storage, disposal, transport or handling or
     Hazardous Materials (collectively, "Environmental Laws"), (B) the Company
     and the Subsidiaries have all permits, authorizations and approvals
     required under any applicable Environmental Laws and are each in compliance
     with their requirements, (C) there are no pending or threatened
     administrative, regulatory or judicial actions, suits, demands, demand
     letters, claims, liens, notices of noncompliance or violation,
     investigation or proceedings relating to any Environmental Law against the
     Company or any of the Subsidiaries and (D) there are no events or
     circumstances that might reasonably be expected to form the basis of an
     order for clean-up remediation, or an action, suit or proceeding by any
     private party or governmental body or agency, against or affecting the
     Company or any of the Subsidiaries relating to Hazardous Materials or any
     Environmental Laws.
 
          (v) The accountants who certified the financial statements and
     supporting schedules included in the Registration Statement are independent
     public accountants as required by the Securities Act.
 
          (vi) The financial statements included in the Registration Statement
     and the Prospectus, together with the related schedules and notes, present
     fairly the financial position of the Company and its consolidated
     subsidiaries at the dates indicated and the statement of operations,
     stockholders' equity and cash flows of the Company and its consolidated
     subsidiaries for the periods specified; said financial statements have been
     prepared in conformity with generally accepted accounting principles
     ("GAAP") applied on a consistent basis throughout the periods involved. The
     supporting schedules, if any, included in the Registration Statement
     present fairly in accordance with GAAP the information required to be
     stated therein. The selected financial data included in the Prospectus
     present fairly the information shown therein and have been compiled on a
     basis consistent with that of the audited financial statements included in
     the Registration Statement.
 
     In lieu of the last paragraph of Section V.(b) of the Base Underwriting
Agreement, the Company and the Underwriters agree that the obligations of the
several Underwriters hereunder and under the Base Underwriting Agreement are
subject to receipt of a letter from counsel to the Company, to the effect that:
 
          Such counsel has participated in conferences with certain officers and
     other representatives of the Company and representatives of the
     Underwriters and representatives of the independent auditors for the
     Company at which the contents of the Registration Statement and the
     Prospectus and related matters were discussed and, although such counsel
     does not pass upon, and does not assume any responsibility for, the
     accuracy, completeness or fairness of the statements contained in the
     Registration Statement or the Prospectus, such counsel advises you that, on
     the basis of the foregoing (relying upon the opinions of officers and other
     representatives of the Company), no facts have come to such counsel's
     attention that lead such counsel to believe that the Registration
     Statement, when such Registration Statement became effective, or the
     Prospectus as of its date and as of the Closing Date, contained or contains
     an untrue statement of a material fact or omitted or omits to state a
     material fact required to be stated therein or necessary to make the
     statements therein (in the case of the Prospectus, in the light of the
     circumstances
 
                                        3
   4
 
     under which they are being made) not misleading (it being understood such
     counsel is not being requested to and need not make any comment with
     respect to (i) the Trustee's Statement of Eligibility on Form T-1, (ii) the
     exhibits to the Registration Statement, (iii) the financial statements, and
     the notes thereto and related schedules, (iv) other financial, accounting
     or statistical data found in or derivable from the financial or internal
     records of the Company and the Subsidiaries and (v) any forward-looking or
     projected financial or statistical data relating to the Company and the
     Subsidiaries, included in the Registration Statement or the Prospectus).
 
     In lieu of the provisions of the second through seventh paragraphs of
Section VII of the Base Underwriting Agreement, the Company and the Underwriters
agree as follows:
 
     The Company agrees to indemnify and hold harmless each Underwriter and each
person, if any, who controls any Underwriter within the meaning of Section 15 of
the Securities Act or Section 20 of the Exchange Act to the extent and in the
manner set forth in clauses (i), (ii) and (iii) below.
 
          (i) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     (or any amendment thereto) or the omission or alleged omission therefrom of
     a material fact required to be stated therein or necessary to make the
     statements therein not misleading or arising out of any untrue statement or
     alleged untrue statement of a material fact included in any preliminary
     prospectus or the Prospectus (or any amendment or supplement thereto if
     used within the period set forth in paragraph (c) of Article VI of the Base
     Underwriting Agreement), or the omission or alleged omission therefrom of a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;
 
          (ii) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission; provided that any such settlement is
     effected with the written consent of the indemnifying party or parties; and
 
          (iii) against any and all expense whatsoever, as incurred (including
     the fees and disbursements of counsel chosen by Credit Suisse First Boston
     Corporation in accordance with and subject to the other terms of this
     Section VII), reasonably incurred in investigating, preparing or defending
     against any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission to the extent that any such expense is
     not paid under (i) or (ii) above;
 
provided, however, that (A) this indemnity agreement shall not apply to any
loss, liability, claim, damage or expense to the extent based upon any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
Underwriter through the Manager expressly for use in the Registration Statement
(or any amendment thereto) or any preliminary prospectus or the Prospectus (or
any amendment or supplement thereto).
 
     Each Underwriter severally agrees to indemnify and hold harmless the
Company, its directors, each of its officers who signed the Registration
Statement, and each person, if any, who controls the Company within the meaning
of Section 15 of the Securities Act or Section 20 of the Exchange Act, against
any and all loss, liability, claim, damage and expense described in the
indemnity contained in the preceding paragraph, as incurred, but only with
respect to untrue statements or omissions, or alleged untrue statements or
omissions, made in the Registration Statement (or any amendment thereto) or any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished
to the Company by such Underwriter through the Manager expressly for use in the
Registration Statement (or any amendment thereto) or such preliminary prospectus
or the Prospectus (or any amendment or supplement thereto).
 
                                        4
   5
 
     Each indemnified party shall give notice as promptly as reasonably
practicable to each indemnifying party of any action commenced against it in
respect of which indemnity may be sought hereunder, but failure to so notify an
indemnifying party shall not relieve such indemnifying party from any liability
hereunder to the extent it is not materially prejudiced as a result thereof and
in any event shall not relieve it from any liability which it may have otherwise
than on account of this indemnity agreement. In the case of Underwriters and
their controlling persons, counsel to such indemnified parties shall be selected
by Credit Suisse First Boston Corporation; and, in the case of the Company and
its controlling persons, directors and officers who signed the Registration
Statement indemnified pursuant to this Section VII, counsel to such indemnified
parties shall be selected by the Company. An indemnifying party may participate
at its own expense in the defense of any such action; provided, however, that
counsel to the indemnifying party shall not (except with the consent of the
indemnified party) also be counsel to the indemnified party. In no event shall
the indemnifying parties be liable for fees and expenses of more than one
counsel (in addition to one local counsel, if necessary, in the applicable
jurisdiction) separate from their own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances,
unless the indemnified party reasonably concludes (on the basis of advice of
counsel) that there is a substantial likelihood of a material conflict of
interest between or among the indemnified parties and/or indemnifying parties on
the conduct of the defense of any such action. No indemnifying party shall,
without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought hereunder (whether or not the
indemnified parties are actual or potential parties thereto), unless such
settlement, compromise or consent (i) includes an unconditional release of such
indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.
 
     If at any time an indemnified party shall have requested (in writing) an
indemnifying party to reimburse the indemnified party for fees and expenses of
its counsel and the indemnified party is entitled to such reimbursement in
accordance with the terms of this Section VII, such indemnifying party agrees
that it shall be liable for any settlement of the nature contemplated by the
preceding paragraph effected without its written consent if (i) such settlement
is entered into more than 45 days after receipt by such indemnifying party of
the aforesaid written request, (ii) such indemnifying party shall have received
written notice of the terms of such settlement at least 30 days prior to such
settlement being entered into and (iii) such indemnifying party shall not have
reimbursed such indemnified party in accordance with such request prior to the
date of such settlement.
 
     If the indemnification provided for herein is for any reason unavailable to
or insufficient to hold harmless an indemnified party in respect of any losses,
liabilities, claims, damages or expenses referred to herein, then each
indemnifying party shall contribute to the aggregate amount of such losses,
liabilities, claims, damages and expenses incurred by such indemnified party, as
incurred, (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and the Underwriters on the
other hand from the offering of the Debentures pursuant to this Agreement or
(ii) if the allocation provided by clause (i) is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of the
Company on the one hand and of the Underwriters on the other hand in connection
with the statements or omissions which resulted in such losses, liabilities,
claims, damages or expenses, as well as any other relevant equitable
considerations.
 
     The relative benefits received by the Company on the one hand and the
Underwriters on the other hand in connection with the offering of the Debentures
pursuant to this Agreement shall be deemed to be in the same respective
proportions as the total net proceeds from the offering of the Debentures
pursuant to this Agreement (before deducting expenses) received by the Company
and the total underwriting discount received by the Underwriters, in each case
as set forth on the cover of the Prospectus bear to the aggregate public
offering price of the Debentures as set forth on such cover.
 
                                        5
   6
 
     The relative fault of the Company on the one hand and the Underwriters on
the other hand shall be determined by reference to, among other things, whether
any such untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by the
Company or by the Underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.
 
     The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant hereto were determined by pro rata allocation
(even if the Underwriters were treated as one entity for such purpose) or by any
other method of allocation which does not take account of the equitable
considerations referred to above. The aggregate amount of losses, liabilities,
claims, damages and expenses incurred by an indemnified party and referred to
above in this Agreement shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in investigating, preparing or
defending against any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever
based upon any such untrue or alleged untrue statement or omission or alleged
omission.
 
     Notwithstanding the provisions of this Agreement, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Debentures underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of any such untrue or
alleged untrue statement or omission or alleged omission.
 
     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.
 
     For purposes of this Agreement, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act shall have the same rights to contribution as such
Underwriter, and each director of the Company, each officer of the Company who
signed the Registration Statement, and each person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act shall have the same rights to contribution as the Company. The
Underwriters' respective obligations to contribute pursuant to this Agreement
are several in proportion to the principal amount of Debentures set forth
opposite their respective names above (as adjusted pursuant to the Defaulted
Securities provision of this Agreement).
 
     All representations, warranties and agreements of the Company and the
Underwriters contained in this Agreement or in certificates of officers of the
Company submitted pursuant hereto, shall remain operative and in full force and
effect, regardless of any investigation made by or on behalf of any Underwriter
or controlling person of any Underwriter, or by or on behalf of the Company or
any director, officer or controlling person of the Company, as the case may be,
and shall survive delivery of the Debentures to the Underwriters.
 
     This Agreement shall be governed by and construed in accordance with the
laws of the State of New York.
 
     Except as otherwise expressly provided herein, the Company will pay or
cause to be paid all expenses incident to the performance of the Company's
obligations under this Agreement, including (i) the preparation, printing and
filing of the Registration Statement (including financial statements and
exhibits) as originally filed and of each amendment thereto, (ii) the
preparation, printing and delivery to the Underwriters of this Agreement, any
Agreement among Underwriters and such other documents as may be required in
connection with the offering, purchase, sale, issuance or delivery of the
Debentures, (iii) the preparation, issuance and delivery of the certificates for
the Debentures to the Underwriters, including any transfer taxes and any stamp
or other duties payable upon the sale, issuance or delivery of the Debentures to
the Underwriters, (iv) the fees and disbursements of the Company's counsel,
accountants and other advisors, (v) the qualification of the Debentures under
state securities or "blue sky" laws, including filing fees and the reasonable
fees and disbursements of counsel for the Underwriters in connection therewith
and in connection with the preparation of the Blue Sky Survey and any supplement
thereto, (vi) the printing and delivery to the Underwriters of copies of the
Prospectus and any amendments or supplements thereto, (vii) the preparation,
 
                                        6
   7
 
printing and delivery to the Underwriters of copies of the Blue Sky Survey and
any supplement thereto and (viii) the fees and expenses of any trustee for the
Debentures.
 
     The Manager may terminate this Agreement, by notice to the Company, at any
time at or prior to the Closing Date (i) if there has been, since the time of
execution of this Agreement or since the respective dates as of which
information is given in the Prospectus, any material adverse change in the
condition, financial or otherwise, or in the earnings, business affairs or
prospects of the Company and the Subsidiaries considered as one enterprise,
whether or not arising in the ordinary course of business, or (ii) if there has
occurred any material adverse change in the financial markets in the United
States, any outbreak of hostilities or escalation thereof or other calamity or
crisis or any change or development involving a prospective change in national
or international political, financial or economic conditions, in each case the
effect of which is such as to make it, in the reasonable judgment of the
Manager, impracticable to market the Debentures or to enforce contracts for the
sale of the Debentures, or (iii) if trading in any securities of the Company has
been suspended or materially limited by the Commission or the New York Stock
Exchange, or if trading generally on the American Stock Exchange or the New York
Stock Exchange or in the Nasdaq National Market has been suspended or materially
limited, or minimum or maximum prices for trading have been fixed, or maximum
ranges for prices have been required, by any of said exchanges or by such system
or by order of the Commission, the National Association of Securities Dealers,
Inc. or any other governmental authority, or (iv) if a banking moratorium has
been declared by either Federal or New York authorities.
 
     If one or more of the Underwriters shall fail on the Closing Date to
purchase the Debentures which it or they are obligated to purchase under this
Agreement (the "Defaulted Securities"), the Manager shall have the right, within
24 hours thereafter, to make arrangements for one or more of the non-defaulting
Underwriters, or any other underwriters, to purchase all, but not less than all,
of the Defaulted Securities in such amounts as may be agreed upon and upon the
terms herein set forth; if, however, the Manager shall not have completed such
arrangements within such 24-hour period, then:
 
          (a) if the number of Defaulted Securities does not exceed 10% of the
     aggregate principal amount of the Debentures to be purchased on such date,
     each of the non-defaulting Underwriters shall be obligated, severally and
     not jointly, to purchase the full amount thereof in the proportions that
     their respective underwriting obligations of Debentures hereunder bear to
     such underwriting obligations of all non-defaulting Underwriters, or
 
          (b) if the number of Defaulted Securities exceeds 10% of the aggregate
     principal amount of the Debentures to be purchased on such date, this
     Agreement shall terminate without liability on the part of any
     non-defaulting Underwriter.
 
No action taken pursuant to this paragraph shall relieve any defaulting
Underwriter from liability in respect of its default. In the event of any such
default which does not result in a termination of this Agreement, either the
Manager or the Company shall have the right to postpone the Closing Date for a
period not exceeding seven days in order to effect, at their expense, any
required changes in the Registration Statement or Prospectus or in any other
documents or arrangements. As used herein, the term "Underwriter" includes any
person substituted for an Underwriter under this paragraph.
 
     This Agreement may be executed in any number of counterparts, each of which
so executed shall be deemed to be an original, but all such counterparts shall
together constitute one and the same instrument. All notices to any party hereto
given or required to be given pursuant to or in connection with this Agreement
shall be given in writing.
