Dear Ladies and Gentlemen:

         Union Tank Car Company, a Delaware corporation (the "Company"),
proposes to sell to the underwriters named in Schedule II hereto (the
"Underwriters"), for whom you (the "Representatives") are acting as
representatives, the principal amount of its securities identified in Schedule
I hereto (the "Securities"), to be issued under an indenture (the "Indenture"),
dated as of January 16, 1997 (as supplemented by the First Supplemental
Indenture, dated as of January 22, 1997), between the Company and Harris Trust
and Savings Bank, as trustee (the "Trustee").  If the firm or firms listed in
Schedule II hereto include only the firm or firms listed in Schedule I hereto,
then the terms "Underwriters" and "Representatives", as used herein, shall each
be deemed to refer to such firm or firms.

         1.      Representations and Warranties.  The Company represents and
warrants to, and agrees with you, that:

                 (a)      The Company meets the requirements for the use of
         Form S-3 under the Securities Act of 1933 (the "Act") and has filed
         with the Securities and Exchange Commission (the "Commission") a
         registration statement (File No. 333-17121) on such Form, including a
         basic prospectus, for registration under the Act of the offering
<PAGE>   2
         and sale of the Securities.  The Company may have filed one or more
         amendments thereto, and may have used a Preliminary Final Prospectus,
         each of which has previously been furnished to you.  Such registration
         statement, as so amended, has become effective.  The offering of the
         Securities is a Delayed Offering (as specified in Schedule I hereto)
         and, although the Basic Prospectus may not include all the information
         with respect to the Securities and the offering thereof required by
         the Act and the rules thereunder to be included in the Final
         Prospectus, the Basic Prospectus includes all such information
         required by the Act and the rules thereunder to be included therein as
         of the Effective Date.  The Company will next file with the Commission
         pursuant to Rules 415 and 424(b)(2) or (5) a final supplement to the
         form of prospectus included in such registration statement relating to
         the Securities and the offering thereof.  As filed, such final
         prospectus supplement shall include all required information with
         respect to the Securities and the offering thereof and, except to the
         extent the Representatives shall agree in writing to a modification,
         shall be in all substantive respects in the form furnished to you
         prior to the Execution Time or, to the extent not completed at the
         Execution Time, shall contain only such specific additional
         information and other changes (beyond that contained in the Basic
         Prospectus and any Preliminary Final Prospectus) as the Company has
         advised you, prior to the Execution Time, will be included or made
         therein.

                 (b)      On the Effective Date, the Registration Statement did
         or will, and when the Final Prospectus is first filed (if required) in
         accordance with Rule 424(b) and on the Closing Date, the Final
         Prospectus (and any supplement thereto) will, comply in all material
         respects with the applicable requirements of the Act, the Securities
         Exchange Act of 1934 (the "Exchange Act") and the Trust Indenture Act
         of 1939 (the "Trust Indenture Act") and the respective rules
         thereunder; on the Effective Date, the Registration Statement did not
         or will not contain any untrue statement of a material fact or omit to
         state any material fact required to be stated therein or necessary in
         order to make the statements therein not misleading; on the Effective
         Date and on the Closing Date the Indenture did or will comply in all
         material respects with the requirements of the Trust Indenture Act and
         the rules thereunder; and, on the Effective Date, the Final
         Prospectus, if not filed pursuant to Rule 424(b), did not or will not,
         and on the date of any filing pursuant to Rule 424(b) and on the
         Closing Date, the Final Prospectus (together with any supplement
         thereto) will not, include any untrue statement of a material fact or
         omit to state a material fact necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading; provided, however, that the Company makes
         no representations or warranties as to (i) that part of the
         Registration Statement which shall constitute the Statement of
         Eligibility and Qualification (Form T-1) under the Trust Indenture Act
         of the Trustee or (ii) the information contained in or omitted from
         the Registration Statement or the Final Prospectus (or any supplement
         thereto) in reliance upon and in conformity with information furnished
         in writing to the Company by or on behalf of any Underwriter through
         the Representatives specifically for inclusion in the Registration
         Statement or the Final Prospectus (or any supplement





                                      -2-
<PAGE>   3
         thereto), it being understood and agreed that the only information
         furnished by the Representatives consists of (i) the stabilization
         language appearing on the top of page S-2 and (ii) the information
         relating to the Underwriters set forth under the caption
         "Underwriting," each as contained in the Preliminary Final Prospectus
         and the Final Prospectus.

                 (c)      The terms which follow, when used in this Agreement,
         shall have the meanings indicated.  The term "the Effective date"
         shall mean each date that the Registration Statement and any
         post-effective amendment or amendments thereto became or become
         effective and each date after the date hereof on which a document
         incorporated by reference in the Registration Statement is filed.
         "Execution Time" shall mean the date and time that this Agreement is
         executed and delivered by the parties hereto.  "Basic Prospectus"
         shall mean the prospectus referred to in paragraph (a) above contained
         in the Registration Statement at the Effective Date including, in the
         case of a Non-Delayed Offering, any Preliminary Final Prospectus.
         "Preliminary Final Prospectus" shall mean any preliminary prospectus
         supplement to the Basic Prospectus which describes the Securities and
         the offering thereof and is used prior to filing of the Final
         Prospectus.  "Final Prospectus" shall mean the prospectus supplement
         relating to the Securities that is first filed pursuant to Rule 424(b)
         after the Execution Time, together with the Basic Prospectus or, if,
         in the case of a Non-Delayed Offering, no filing pursuant to Rule
         424(b) is required, shall mean the form of final prospectus relating
         to the Securities, including the Basic Prospectus, included in the
         Registration Statement at the Effective Date.  "Registration
         Statement" shall mean the registration statement referred to in
         paragraph (a) above, including incorporated documents, exhibits and
         financial statements, as amended at the Execution Time (or, if not
         effective at the Execution Time, in the form in which it shall become
         effective) and, in the event any post-effective amendment thereto
         becomes effective prior to the Closing Date (as hereinafter defined),
         shall also mean such registration statement as so amended.  Such term
         shall include any Rule 430A Information deemed to be included therein
         at the Effective Date as provided by Rule 430A.  "Rule 415", "Rule
         424", "Rule 430A" and "Regulation S-K" refer to such rules or
         regulation under the Act.  "Rule 430A Information" means information
         with respect to the Securities and the offering thereof permitted to
         be omitted from the Registration Statement when it becomes effective
         pursuant to Rule 430A.  Any reference herein to the Registration
         Statement, the Basic Prospectus, any Preliminary Final Prospectus or
         the Final Prospectus shall be deemed to refer to and include the
         documents incorporated by reference therein pursuant to Item 12 of
         Form S-3 which were filed under the Exchange Act on or before the
         Effective Date of the Registration Statement or the issue date of the
         Basic Prospectus, any Preliminary Final Prospectus or the Final
         Prospectus, as the case may be; and any reference herein to the terms
         "amend", "amendment" or "supplement" with respect to the Registration
         Statement, the Basic Prospectus, any Preliminary Final Prospectus or
         the Final Prospectus shall be deemed to refer to and include the
         filing of any document under the Exchange Act after the Effective Date
         of the Registration Statement or the issue date of the Basic





                                      -3-
<PAGE>   4
         Prospectus, any Preliminary Final Prospectus or the Final Prospectus,
         as the case may be, deemed to be incorporated therein by reference.  A
         "Non-Delayed Offering" shall mean an offering of securities which is
         intended to commence promptly after the effective date of a
         registration statement, with the result that, pursuant to Rules 415
         and 430A, all information (other than Rule 430A Information) with
         respect to the securities so offered must be included in such
         registration statement at the effective date thereof.  A "Delayed
         Offering" shall mean an offering of securities pursuant to Rule 415
         which does not commence promptly after the effective date of a
         registration statement, with the result that only information required
         pursuant to Rule 415 need be included in such registration statement
         at the effective date thereof with respect to the securities so
         offered.  Whether the offering of the Securities is a Non-Delayed
         Offering or a Delayed Offering shall be set forth in Schedule I
         hereto.

                 (d)      The consolidated financial statements incorporated by
         reference in the Registration Statement and Final Prospectus present
         fairly the consolidated financial position of the Company and its
         subsidiaries as at the dates indicated and the consolidated results of
         their operations and cash flows for the periods specified and have
         been prepared in conformity with generally accepted accounting
         principles applied on a consistent basis during the periods involved,
         except as indicated therein, and the supporting schedules incorporated
         by reference in the Registration Statement present fairly the
         information required to be stated therein.

                 (e)      The documents incorporated by reference in the Final
         Prospectus, at the time they were or hereafter are filed with the
         Commission, complied and will comply in all material respects with the
         requirements of the Exchange Act, and the rules and regulations
         thereunder.

                 (f)      Since the respective dates as of which information is
         given in the Registration Statement and the Final Prospectus, except
         as otherwise stated therein or contemplated thereby, there has been no
         material adverse change in the condition, financial or otherwise,
         results of operations or general affairs of the Company and its
         subsidiaries, taken as a whole.

                 (g)      The Company and each Significant Subsidiary (with

         Act) of the Company has been duly incorporated and is validly existing
         as a corporation in good standing under the laws of the jurisdiction
         in which it is chartered or organized, with full corporate power and
         authority to own its properties and conduct its business as described
         in the Final Prospectus, and is duly qualified to do business as a
         foreign corporation and is in good standing under the laws of each
         jurisdiction which requires such qualification wherein it owns or
         leases material properties or conducts material business, except in
         such jurisdictions in which the failure to so qualify would not have a
         material adverse effect on the Company and its subsidiaries taken as a
         whole.  The Company owns either directly or indirectly, all of the
         issued and outstanding capital stock of its





                                      -4-

         subsidiaries, free and clear of any lien, adverse claim, security
         interest or other encumbrance.

         Agreement, the Indenture and the Securities, the consummation by the
         Company of the transactions herein and therein contemplated, and the
         compliance by the Company with the terms hereof and thereof do not and
         will not conflict with, or result in a breach of any of the terms or
         provisions of, or constitute a default under, the Certificate of
         Incorporation or By-Laws, as amended, of the Company, or any of its
         subsidiaries, or any material indenture, mortgage, or other agreement
         or instrument to which the Company or any of its subsidiaries is a
         party or by which any of its properties are bound, or any applicable
         law, rule, regulation, judgment, order or decree of any government,
         governmental instrumentality or court, domestic or foreign, having
         jurisdiction over the Company or any of its subsidiaries or any of its
         properties; and, assuming due authorization, execution and delivery by
         all parties thereto other than the Company, no consent, approval,
         authorization, order or license of, or filing with or notice to any
         government, governmental instrumentality, regulatory body or authority
         or court, domestic or foreign, is required for the valid
         authorization, issuance and delivery of the Securities, the valid
         authorization, execution, delivery and performance by the Company of

         Securities, except (w) such as are required under the Act, the Trust
         Indenture Act and the securities or Blue Sky laws of the various

         authorization, execution and delivery by the other parties thereto,
         have each been duly authorized by the Company and, when executed and

reliance upon the representations and warranties herein set forth, the Company
agrees to sell each Underwriter, and each Underwriter agrees, severally and not

arrangements, the respective principal amounts of Securities to be purchased by
the Underwriters shall be as set forth in Schedule II hereto.  Securities to be
purchased by the Underwriters are herein called the "Underwriters' Securities".

         3.      Delivery and Payment.  Delivery of and payment for the
Underwriters' Securities shall be made on the date and at the time specified in
Schedule I hereto (or such later date not later than five business days after

(such date and time of delivery and payment for the Underwriters' Securities

Securities shall be made to the Representatives for the respective accounts of
the several Underwriters against payment by the several Underwriters through

inspection, checking and packaging by the Representatives in New York, New
York, not later than 1:00 PM on the business day prior to the Closing Date.

         4.      Agreements.  The Company agrees with you that:

                 (a)      The Company will use its best efforts to cause the
         Registration Statement, if not effective at the Execution Time, and
         any amendment thereto, to become effective.  Prior to the termination
         of the offering of the Securities, the Company will not file any
         amendment of the Registration Statement or supplement (including the
         Final Prospectus or any Preliminary Final Prospectus) to the Basic
         Prospectus unless the Company has furnished you a copy for your review
         prior to filing and will not file any such proposed amendment or
         supplement to which you reasonably object.  Subject to the foregoing
         sentence, the Company will cause the Final Prospectus, properly
         completed and any supplement thereto to be filed with the Commission
         pursuant to the applicable paragraph of Rule 424(b) within the time
         period prescribed and will provide evidence satisfactory to the
         Representatives of such





                                      -6-

         timely filing.  The Company will promptly advise the Representatives
         (i) when the Registration Statement, it not effective at the Execution
         Time, and any amendment thereto, shall have become effective, (ii)
         when the Final Prospectus, and any supplement thereto, shall have been
         filed with the Commission pursuant to Rule 424(b), (iii) when, prior
         to termination of the offering of the Securities, any amendment to the
         Registration Statement shall have been filed or become effective, (iv)
         of any request by the Commission for any amendment of the Registration
         Statement or supplement to the Final Prospectus or for any additional
         information, (v) of the issuance by the Commission of any stop order
         suspending the effectiveness of the Registration Statement or the
         institution or threatening of any proceeding for that purpose and (vi)
         of the receipt by the Company of any notification with respect to the
         suspension of the qualification of the Securities for sale in any
         jurisdiction or the initiation or threatening of any proceeding for
         such purpose.  The Company will use its best efforts to prevent the
         issuance of any such stop order and, if issued, to obtain as soon as
         possible the withdrawal thereof.

                 (b)      If, at any time when a prospectus relating to the
         Securities is required to be delivered under the Act, any event occurs
         as a result of which the Final Prospectus as then supplemented would
         include any untrue statement of a material fact or omit to state any
         material fact necessary to make the statements therein, in the light
         of the circumstances under which they were made, not misleading, or if
         it shall be necessary to amend the Registration Statement or
         supplement the Final Prospectus to comply with the Act or the Exchange
         Act or the respective rules and regulations thereunder, the Company
         promptly will (i) prepare and file with the Commission, subject to
         paragraph (a) of this Section 4, an amendment or supplement which will
         correct such statement or omission or an amendment which will effect
         such compliance and (ii) supply any supplemented Prospectus to you in
         such quantities as you may reasonably request.

                 (c)      As soon as practicable, the Company will make
         generally available to its security holders and to the Underwriters an
         earnings statement or statements of the Company and its subsidiaries
         which will satisfy the provisions of Section 11(a) of the Act and the
         applicable rules and regulations thereunder.

                 (d)      The Company will furnish to you and your counsel,
         without charge, signed copies of the Registration Statement (including
         exhibits thereto) and, so long as delivery of a prospectus by an
         Underwriter or a dealer may be required by the Act, as many copies of
         each Preliminary Final Prospectus and the Final Prospectus and any
         amendments thereof and supplements thereto as you may reasonably
         request.  The Company will pay the expenses of printing all documents
         relating to the offering.

                 (e)      The Company will cooperate with you and your counsel
         to arrange for the qualification of the Securities for sale under the
         laws of such jurisdictions as you may reasonably designate, will
         maintain such qualifications in effect so long as





                                      -7-

         required for the distribution of the Securities and will cooperate
         with you and your counsel to arrange for the determination of the
         legality of the Securities for purchase by institutional investors;
         provided, however, that the Company will not be required to qualify to
         do business in any jurisdiction in order to effect such qualification.

                 (f)      Between the date of this Agreement and the Closing
         Date, the Company will not, without the consent of the
         Representatives, offer, sell or contract to sell, or otherwise dispose
         of, directly or indirectly, or announce the offering of, any debt
         securities issued or guaranteed by the Company (other than the
         Securities).

                 (g)      The Company confirms as of the date hereof that it is
         in compliance with all provisions of Section 1 of Laws of Florida,
         Chapter 92-198, An Act Relating to Disclosure of Doing Business with
         Cuba, and the Company further agrees, if necessary, that if the
         Company commences engaging in business with the government of Cuba or
         with any person or affiliate located in Cuba after the date the
         Registration Statement becomes or has become effective with the
         Commission or with the Florida Department of Banking and Finance (the
         "Department"), whichever date is later, or if the information reported
         in the Final Prospectus, if any, concerning the Company's business
         with Cuba or with any person or affiliate located in Cuba changes in
         any material way, the Company will provide the Department notice of
         such business or change, as appropriate, in a form acceptable to the
         Department.

         the opinion of Robert W. Webb, Esq., general counsel of the Company,
         and Osler, Hoskin & Harcourt, special Canadian counsel to the Company,
         as to Canadian law matters), dated the Closing Date, to the effect
         that:

                          (i)  the Company and each of its Significant
                 Subsidiaries has been duly incorporated and is validly
                 existing as a corporation in good standing under the laws of
                 the jurisdiction in which it is chartered or organized, with
                 full corporate power and authority to own its properties and
                 conduct its business as described in the Final Prospectus, and
                 is duly qualified to do business as a foreign corporation and
                 is in good standing under the laws of each jurisdiction which
                 requires such qualification wherein it owns or leases material
                 properties or conducts material business, except in such
                 jurisdictions in which the failure to so qualify would not
                 have a material adverse effect on the Company and its
                 subsidiaries taken as a whole;

                          (ii)  all the outstanding shares of capital stock of
                 each of the Company's subsidiaries have been duly and validly
                 authorized and issued and are fully paid and nonassessable,
                 and, all such capital stock is owned directly or indirectly by
                 the Company, free and clear of any perfected security interest
                 and, to the knowledge of such counsel, after due inquiry, any
                 other security interest, claims, liens or encumbrances;

                          (iii)  the Indenture has been duly authorized,
                 executed and delivered by the Company, has been duly qualified
                 under the Trust Indenture Act, and assuming due authorization,
                 execution and delivery thereof by the Trustee, the Indenture
                 constitutes a legal, valid and binding obligation of the
                 Company enforceable against the Company in accordance with its
                 terms, except as may be limited by bankruptcy, insolvency,
                 reorganization, moratorium or other similar laws affecting
                 enforcement of creditors' rights generally and by general
                 principles of equity (regardless of whether enforcement is
                 considered in a proceeding in equity or at law);

                          (iv)  to the best knowledge of such counsel, there is
                 no pending or threatened action, suit or proceeding before any
                 court or governmental agency, authority or body or any
                 arbitrator involving the Company or any of its subsidiaries,
                 of a character required to be disclosed in the Registration
                 Statement which is not adequately disclosed in the Final
                 Prospectus, and there is no franchise, contract or other
                 document of a character required to be described in the
                 Registration Statement or Final Prospectus, or to be filed as
                 an exhibit, which is not described or filed as required; and
                 the statements included or incorporated in the Final
                 Prospectus describing any legal proceedings or material
                 contracts or agreements relating to the Company fairly
                 summarize such matters;

                          (v)  the Registration Statement has become effective
                 under the Act; any required filing of the Basic Prospectus,

                 in the manner and within the time period required by Rule

                 suspending the effectiveness of the Registration Statement has
                 been issued, no proceedings for that purpose have been
                 instituted or threatened, and the Registration Statement and
                 the Final Prospectus (other than the financial statements and
                 other financial and statistical information contained therein
                 as to which such counsel need express no opinion) comply as to
                 form in all material respects with the applicable requirements
                 of the Act, the Exchange Act and the Trust Indenture Act and
                 the respective rules thereunder;

                          (vi)  this Agreement has been duly authorized,
                 executed and delivered by the Company and, assuming due
                 authorization, execution and delivery by you, constitutes a
                 valid and binding obligation of the Company, enforceable
                 against the Company in accordance with its terms, except (i)
                 as may be limited by bankruptcy, insolvency, reorganization,
                 moratorium or other similar laws affecting enforcement of
                 creditors' rights generally and by general principles of
                 equity (regardless of whether enforcement is considered in a
                 proceeding in equity or at law) and (ii) as to provisions of
                 this Agreement relating to indemnification or contribution for
                 liabilities arising under the Act, as to which such counsel
                 need express no opinion;

                          (vii)  no authorization, approval, consent, order or
                 license of or filing with or notice to any government,

                 Company of the transactions contemplated by this Agreement and
                 the Indenture, except such as have been obtained under the Act
                 and the Trust Indenture Act and such as may be required under
                 the blue sky laws of any jurisdiction in connection with the
                 purchase and distribution of the Securities by you and such
                 other approvals (specified in such opinion) as have been
                 obtained;

                          (viii)  neither the execution and delivery of the
                 Indenture, the issue and sale of the Securities, nor the
                 consummation of any other of the transactions herein
                 contemplated nor the fulfillment of the terms hereof will
                 conflict with, result in a breach or violation of, or
                 constitute a default under any law or the charter or by-laws
                 of the Company or the terms of any indenture or other
                 agreement or instrument known to such counsel and to which the
                 Company or any of its subsidiaries is a party or bound or any
                 judgment, order or decree known to such counsel to be
                 applicable to the Company or any of its subsidiaries of any
                 court, regulatory body, administrative agency,

                 governmental body or arbitrator having jurisdiction over the
                 Company or any of its subsidiaries;

                          (ix)  the Company is not an "investment company" or a
                 company "controlled" by an "investment company" within the
                 meaning of the Investment Company Act of 1940, as amended;

                          (x)  on the Closing Date, assuming due execution and
                 delivery of the Securities by the Trustee and the Company, the
                 Securities when issued against payment therefor as provided
                 herein will constitute valid and binding obligations of the
                 Company, enforceable against the Company, in accordance with
                 their terms, except as may be limited by bankruptcy,
                 insolvency, reorganization, moratorium or other similar laws
                 affecting enforcement of creditors' rights generally and by
                 general principles of equity (regardless of whether
                 enforcement is considered in a proceeding in equity or at
                 law), and the holders of the Securities will be entitled to
                 the benefits of the Indenture; and

                          (xi)  the Indenture and the Securities conform in all
                 material respects to the descriptions thereof contained in the
                 Final Prospectus.

         In passing on the form of the Registration Statement and the Final
         Prospectus and each amendment and supplement thereto, such counsel may
         state that it has not independently verified the accuracy,
         completeness or fairness of the statements made or included therein
         and takes no responsibility therefor and that such opinion is based
         upon such counsel's examination of the Registration Statement, the
         Final Prospectus as amended or supplemented, its activities in
         connection with the preparation thereof and its participation in
         conferences with certain officers and employees of the Company, its
         subsidiaries and its affiliates and with representatives of Ernst &
         Young LLP and any others referred to in such opinion, and subject to
         the same qualifications, such counsel may also state that, although
         they are not passing upon, and do not assume any responsibility for,
         the accuracy, completeness or fairness of the statements contained in
         the Registration Statement and Final Prospectus and have not made any
         independent check or verification thereof, nothing has come to their
         attention in their examination of the Registration Statement, their
         participation in the preparation thereof and participation in the
         above-referenced conferences that has caused them to believe that the
         Registration Statement, at the time it became effective, contained an
         untrue statement of a material fact or omitted to state a material
         fact required to be stated therein or necessary to make the statements
         therein not misleading, or the Final Prospectus, as of its date and as
         of the Closing Date, contained an untrue statement of a material fact
         or omitted to state a material fact necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading.

                          the Company in this Agreement are true and correct in
                          all material respects on and as of the Closing Date
                          with the same effect as if made on the Closing Date

                          effectiveness of the Registration Statement has been

                          proceedings for that purpose have been instituted or
                          threatened; and

                          Prospectus (exclusive of any supplement thereto).

                 (e)      At the Execution Time and at the Closing Date, Ernst
         & Young LLP shall have furnished to you a letter or letters, dated,
         respectively, as of the Execution Time and as of the Closing Date, in

         independent auditors within the meaning of the Act and the applicable
         published rules and regulations thereunder and stating in effect that:

                          (i)  in their opinion the audited financial
                 statements and financial statement schedules included or
                 incorporated in the Registration Statement and the Final
                 Prospectus and reported on by them comply in form in all
                 material respects with the applicable accounting.requirements
                 of the Act and the Exchange Act and the related published
                 rules and regulations;

                          (ii)  on the basis of a reading of the latest
                 unaudited financial statements made available by the Company
                 and its subsidiaries; carrying out certain specified
                 procedures (but not an examination in accordance with
                 generally accepted auditing standards) which would not
                 necessarily reveal matters of significance with respect to the
                 comments set forth in such letter; a reading of the minutes of
                 the meetings of the stockholders, directors and executive
                 committees of the Company and the Subsidiaries; and inquiries
                 of certain officials of the Company who have responsibility
                 for financial and accounting matters of the Company and its
                 subsidiaries as to transactions and events subsequent to the
                 date of the most recent audited financial statements in or
                 incorporated in the Final Prospectus, nothing came to their
                 attention which caused them to believe that:

                                  (1)  any unaudited financial statements
                          included or incorporated in the Registration
                          Statement and the Final Prospectus do not comply in
                          form in all material respects with applicable
                          accounting requirements and with the published rules
                          and regulations of the Commission with respect to
                          financial statements included or incorporated in
                          quarterly reports on Form-10-Q under the Exchange
                          Act; and said unaudited financial statements are not
                          in conformity with generally accepted accounting
                          principles applied on a basis substantially
                          consistent with that of the audited financial
                          statements included or incorporated in the
                          Registration Statement and the Final Prospectus;

                                  (2)  with respect to the period subsequent to
                          the date of the most recent financial statements
                          (other than any capsule information), audited or
                          unaudited, in or incorporated in the Registration
                          Statement and the Final Prospectus, there were any
                          changes, at a specified date not more than five
                          business days prior to the date of the letter, in the
                          borrowed debt of the Company and its subsidiaries or
                          capital stock of the Company, decreases in the
                          stockholders' equity of the Company and its
                          subsidiaries as compared with the amounts shown on
                          the most recent consolidated balance sheet included
                          or incorporated in the Registration Statement and the
                          Final Prospectus, or for the period from the date of
                          the most recent financial statements included or
                          incorporated in the Registration Statement and the
                          Final Prospectus to such specified date there were
                          any decreases, as compared with the corresponding
                          period in the preceding year or quarter, as the case
                          may be in total revenues from net sales and services,
                          or in income before income taxes or net income, of
                          the Company and its subsidiaries, except in all
                          instances for changes or decreases set forth in such
                          letter, in which case the letter shall be accompanied
                          by an explanation by the Company as to the
                          significance thereof unless said explanation is not
                          deemed necessary by the Representatives; or

<PAGE>   14
                                  (3)  the amounts included in any unaudited
                          "capsule" information included or incorporated in the
                          Registration Statement and the Final Prospectus do
                          not agree with the amounts set forth in the unaudited
                          financial statements for the same periods or were not
                          determined on a basis substantially consistent with
                          that of the corresponding amounts in the audited
                          financial statements included or incorporated in the
                          Registration Statement and the Final Prospectus; and

                          (iii)  they have performed certain other specified
                 procedures as a result of which they determined that certain
                 information of an accounting, financial or statistical nature
                 (which is limited to accounting, financial or statistical
                 information derived from the general accounting records of the
                 Company and its subsidiaries) set forth in the Registration
                 Statement and the Final Prospectus and in Exhibit 12 to the
                 Registration Statement, including the information included or
                 incorporated in the Company's Annual Report on Form 10-K,
                 incorporated in the Registration Statement and the Prospectus,
                 and the information included in the "Management's Discussion
                 and Analysis of Financial Condition and Results of Operations"
                 included or incorporated in the Company's Quarterly Reports on
                 Form 10-Q, incorporated in the Registration Statement and the
                 Final Prospectus, agrees with the accounting records of the
                 Company and its subsidiaries, excluding any questions of legal
                 interpretation.

                 References to the Final Prospectus in this paragraph (e)
include any supplement thereto at the date of the letter.

                 (f)      Subsequent to the Execution Time or, if earlier, the
         dates as of which information is given in the Registration Statement
         (exclusive of any amendment thereof) and the Final Prospectus
         (exclusive of any supplement thereto), there shall not have been (i)
         any change or decrease specified in the letter or letters referred to
         in paragraph (e) of this Section 5 or (ii) any change, or any
         development involving a prospective change, in or affecting the
         business or properties of the Company and its subsidiaries the effect
         of which, in any case referred to in clause (i) or (ii) above, is, in
         the judgment of the Representatives, so material and adverse as to
         make it impractical or inadvisable to proceed with the offering or
         delivery of the Securities as contemplated by the Registration
         Statement (exclusive of any amendment thereof) and the Final
         Prospectus (exclusive of any supplement thereto).

                 (g)      On the Closing Date, the Securities shall be rated at
         least "A3" by Moody's Investor's Service Inc. and "A" by Standard &
         Poor's Corporation, and the Company shall have delivered to the
         Representatives a letter, dated the Closing Date, from each such
         rating agency, or other evidence satisfactory to the Representatives,
         confirming that the Securities have such ratings.





                                      -14-
<PAGE>   15
                 (h)      Subsequent to the Execution Time and prior to the
         Closing Date, there shall not have occurred any downgrading nor shall
         any notice have been given of (i) any intended or potential
         downgrading or (ii) any review or possible change in the rating
         accorded the Company's debt securities by the above-mentioned rating
         agencies as of the Execution Time.

                 (i)      The Company shall have entered into the Indenture and
         the Representatives shall have received original counterparts thereof
         and of all other documents and agreements entered into in connection
         therewith.

                 (j)      Prior to the Closing Date, the Company shall have
         furnished to you such further information, certificates and documents
         as you may reasonably request.

         If any of the conditions specified in this Section 5 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to you and your counsel, this Agreement and all your obligations
hereunder may be canceled at, or at any time prior to, the Closing Date by you.
Notice of such cancellation shall be given to the Company in writing or by
telephone or telegraph confirmed in writing.

         6.  Reimbursement of the Underwriters' Expenses.  If the sale of the
Securities provided for herein is not consummated because any condition to your
obligation set forth in Section 5 hereof is not satisfied, because of any
termination pursuant to Section 9 hereof or because of any refusal, inability
or failure on the part of the Company to perform any agreement herein or comply
with any provision hereof other than by reason of a default by you, the Company
will reimburse you upon demand for all out-of-pocket expenses (including
reasonable fees and disbursements of counsel) that shall have been incurred by
you in connection with the proposed purchase and sale of the Securities.

         7.  Indemnification and Contribution.  (a)  The Company agrees to
indemnify and hold harmless each Underwriter, the directors, officers employees
and agents of each Underwriter and each person who controls any Underwriter
within the meaning of either the Act or the Exchange Act against any and all
losses, claims, damages or liabilities, joint or several, to which they or any
of them may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise
out of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the registration statement for the registration of
the Securities as originally filed or in any amendment thereof, or in the Basic
Prospectus, any Preliminary Final Prospectus or the Final Prospectus, or in any
amendment thereof or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
agrees to reimburse each such indemnified party, as incurred, for any legal or
other expenses reasonably incurred





                                      -15-
<PAGE>   16
by them in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the Company will not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any such untrue statement or alleged
untrue statement or omission or alleged omission made therein in reliance upon
and in conformity with written information furnished to the Company by or on
behalf of any Underwriter through the Representatives specifically for
inclusion therein, it being understood and agreed that the only information
furnished by the Representatives consists of (i) the stabilization language
appearing on the top of page S-2 and (ii) the information relating to the
Underwriters set forth under the caption "Underwriting," each as contained in
the Preliminary Final Prospectus and the Final Prospectus; provided, further
that such indemnity with respect to any Preliminary Final Prospectus shall not
inure to your benefit (or to the benefit of any person controlling you) if the
person asserting any such loss, claim, damage or liability purchased the
securities which are the subject thereof did not receive a copy of the Final
Prospectus (or any amendments thereof or supplements thereto), excluding
documents incorporated therein by reference, at or prior to the confirmation of
the sale of such Securities to such person in any case where such delivery is
required by the Act and the untrue statement or omission of a material fact in
such Preliminary Final Prospectus was corrected in the Final Prospectus (or any
amendments thereof or supplements thereto).  This indemnity agreement will be
in addition to any liability which the Company may otherwise have.

                 (b)  Each Underwriter severally agrees to indemnify and hold
harmless the Company, each of its directors, each of its officers who signs the
Registration Statement, and each person who controls the Company within the
meaning of either the Act or the Exchange Act, to the same extent as the
foregoing indemnity from the Company to each Underwriter, but only with
reference to written information relating to such Underwriter furnished to the
Company by or on behalf of such Underwriter through the Representatives
specifically for inclusion in the documents referred to in the foregoing
indemnity.  This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have.

                 (c)  Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying
party under this Section 7, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure
results in the forfeiture by the indemnifying party of substantial rights and
defenses and (ii) will not, in any event, relieve the indemnifying party from
any obligations to any indemnified party other than the indemnification
obligation provided in paragraph (a) or (b) above.  The indemnifying party
shall be entitled to appoint counsel of the indemnifying party's choice at the
indemnifying party's expense to represent the indemnified party in any action
for which indemnification is sought (in which case the indemnifying party shall
not thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be





                                      -16-
<PAGE>   17
satisfactory to the indemnified party.  Notwithstanding the indemnifying
party's election to appoint counsel to represent the indemnified party in an
action, the indemnified party shall have the right to employ separate counsel
(including local counsel), and the indemnifying party shall bear the reasonable
fees, costs and expenses of such separate counsel if (i) the use of counsel
chosen by the indemnifying party to represent the indemnified party would
present such counsel with a conflict of interest, (ii) the actual or potential
defendants in, or targets of, any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have
reasonably concluded that there may be legal defenses available to it and/or
other indemnified parties which are different from or additional to those
available to the indemnifying party, (iii) the indemnifying party shall not
have employed counsel satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of the institution of
such action or (iv) the indemnifying party shall authorize the indemnified
party to employ separate counsel at the expense of the indemnifying party.  An
indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.

                 (d)  In the event that the indemnity provided in paragraph (a)
or (b) of this Section 7 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters agree to
contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Company and one or more of
the Underwriters may be subject in such proportion as is appropriate to reflect
the relative benefits received by the Company and by the Underwriters from the
offering of the securities; provided, however, that in no case shall any
Underwriter (except as may be provided in any agreement among underwriters
relating to the offering of the Securities) be responsible for any amount in
excess of the underwriting discount or commission applicable to the Securities
purchased by such Underwriter hereunder.  If the allocation provided by the
immediately preceding sentence is unavailable for any reason, the Company and
the Underwriters shall contribute in such proportion as is appropriate to
reflect not only such relative benefits but also the relative fault of the
Company and of the Underwriters in connection with the statements or omissions
which resulted in such Losses as well as any other relevant equitable
considerations.  Benefits received by the Company shall be deemed to be equal
to the total net proceeds from the Offering (before deducting expenses), and
benefits received by the Underwriters shall be deemed to be equal to the total
underwriting discounts and commissions, in each case as set forth on the cover
page of the Final Prospectus.  Relative fault shall be determined by reference
to whether any alleged untrue statement or omission relates to information
provided by the Company or the Underwriters.  The Company and the Underwriters
agree that it would not be just and equitable if contribution were determined
by pro rata allocation or any other method of





                                      -17-
<PAGE>   18
allocation which does not take account of the equitable considerations referred
to above.  Notwithstanding the provisions of this paragraph (d), no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty
of such fraudulent misrepresentation.  For purposes of this Section 7, each
person who controls an Underwriter within the meaning of either the Act or the
Exchange Act and each director, officer, employee and agent of an Underwriter
shall have the same rights to contribution as such Underwriter, and each person
who controls the Company within the meaning of either the Act or the Exchange
Act, each officer of the Company who shall have signed the Registration
Statement and each director of the Company shall have the same rights to
contribution as the Company, subject in each case to the applicable terms and
conditions of this paragraph (d).

         8.  Termination.  This Agreement shall be subject to termination in
your absolute discretion by notice given to the Company prior to delivery of
and payment for the Securities, if prior to such time (i) trading in securities
generally on the New York Stock Exchange shall have been suspended or limited
or minimum prices shall have been established on such Exchange, (ii) a banking
moratorium shall have been declared either by Federal, New York State or
Illinois State authorities or (iii) there shall have occurred any outbreak or
material escalation of hostilities or other calamity or crisis the effect of
which on the financial markets of the United States is such as to make it, in
your judgment, impracticable to market the Securities.

         9.  Representations and Indemnities to Survive.  The respective
agreements, representations, warranties, indemnities and other statements of
the Company or its officers and of you set forth in or made pursuant to this
Agreement will remain in full force and effect, regardless of any investigation
made by or on behalf of you or the Company or any of its officers, directors or
controlling persons referred to in Section 7 hereof, and will survive delivery
of and payment for the Securities.  The provisions of Sections 6 and 7 hereof
shall survive the termination or cancellation of this Agreement.

         10.  Notices.  All communications hereunder will be in writing and
effective only on receipt, and, if sent to you, will be mailed, delivered or
telegraphed and confirmed in the case of Solomon Brothers Inc at 7 World Trade
Center, New York, New York 10048, Attention:  Legal Department; in the case of

Attention:  Legal Department; or, if sent to the Company, will be mailed,
delivered or telegraphed and confirmed to it at 225 West Washington Street,

         11.  Successors.  This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the
officers and directors and controlling persons referred to in Section 7 hereof,
and no other person will have any right or obligation hereunder.

time the Security is authenticated, the Security or coupon shall be valid and
binding nevertheless.

         (c)  A Security shall not be valid until authenticated by the manual
signature of the Trustee or an Authenticating Agent and no coupon shall be
valid until the Security to which it appertains has been so authenticated.
Such signature shall be conclusive evidence that the Security has been
authenticated under this Indenture.  Each Unregistered Security shall be dated
as provided in connection with the establishment of the Series thereof or, if
no such date is so specified, the date of its original issuance and each
Registered Security shall be dated the date of its authentication.

         (d)  The Trustee shall at any time, and from time to time,
authenticate and deliver Securities of any Series executed and delivered by the
Company for original issue, upon receipt by the Trustee of (i) a Company Order
for the authentication and delivery of such Securities, (ii) if the terms and
form or forms of the Securities of such Series have been established by or
pursuant to a Board Resolution as permitted by Section 2.2, a copy of such
Board Resolution and any certificate that may be required pursuant to Section
2.2(b) and (iii) an Opinion of Counsel stating:

                 (1)  if the form of such Securities has been established by or
         pursuant to a Board Resolution as permitted by Section 2.2, that such
         form has been established in conformity with the provisions of this
         Indenture;

                 (2)  if the terms of such Securities have been established by
         or pursuant to a Board Resolution as permitted by Section 2.2, that
         such terms have been established in conformity with the provisions of
         this Indenture; and

                 (3)  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, will constitute valid
         and legally binding obligations of the Company, enforceable in
         accordance with their terms, subject to bankruptcy, insolvency,
         reorganization and other laws of general applicability relating to or
         affecting the enforcement of creditors' rights and to general equity
         principles;

provided, however, that in the case of any Series issuable in Tranches, if the
Trustee has previously received the documents referred to in Section 2.3(d)
(i), (ii) and (iii) with respect to any Tranche of such Series, the Trustee
shall authenticate and deliver Securities of such Series executed and delivered
by the Company for original issue upon receipt by the Trustee of the applicable
Company Notice.

         Notwithstanding the foregoing, until the Company has delivered an
Officers' Certificate to the Trustee and the Registrar stating that, as a
result of the action described, the Company would not suffer adverse
consequences under the provisions of United States law or regulations in effect
at the time of the delivery of Unregistered Securities, (i) delivery of
Unregistered Securities will be made only outside the United States and (ii)
Unregistered Securities will be released in definitive form, whether in the
form of a Global Security or otherwise, to the person entitled to physical
delivery thereof only upon presentation of a certificate in the form prescribed
by the Company in such Officers' Certificate.





                                      -13-

         (e)  The aggregate Principal amount of Securities of any Series
outstanding at any time may not exceed any limit upon the maximum Principal
amount for such Series set forth in the Board Resolution (or certificate of an
Officer or Officers) or supplemental indenture pursuant to Section 2.2.

         (f)  At any time the Trustee may appoint an Authenticating Agent or
Agents with respect to one or more Series of Securities which Authenticating
Agent shall be authorized to act on behalf of the Trustee to authenticate
Securities of such Series, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder.  Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.  Each Authenticating Agent shall be
acceptable to the Company.

         An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company.  Upon receiving such a
notice of resignation or upon such a termination, the Trustee may appoint a
successor Authenticating Agent which shall be acceptable to the Company.  Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.

         The Company agrees to pay to each Authenticating Agent from time to
time (unless such Authenticating Agent shall otherwise agree) reasonable
compensation for its services under this Section.

SECTION 2.4.  Registrar and Paying Agent.

         The Company may maintain in the Borough of Manhattan, The City of New
York, State of New York, an office or agency where, unless otherwise restricted
by the provisions of Section 2.15, Registered Securities may be presented for
registration of transfer or for exchange ("Registrar") and an office or agency
where (subject to Sections 2.5(c) and 2.8(b)) Securities may be presented for
payment or, in the case of Unregistered Securities, for exchange ("Paying
Agent").  With respect to any Series of Securities issued in whole or in part
as Unregistered Securities, the Company shall maintain one or more Paying
Agents located outside the United States and shall maintain such Paying Agents
for a period of two years after the Principal of such Unregistered Securities
has become due and payable.  During any period thereafter for which it is
necessary in order to conform to United States tax law or regulations, the
Company shall maintain a Paying Agent outside the United States to which the
Unregistered Securities or coupons appertaining thereto may be presented for
payment and will provide the necessary funds therefor to such Paying Agent upon
reasonable notice.  The Registrar shall keep a register with respect to each
Series of Securities issued in whole or in part as Registered Securities and to
their transfer and exchange.  The Company may appoint one or more co-Registrars
and one or more additional Paying Agents for each Series of Securities and the
Company may terminate the appointment of any co-Registrar or Paying Agent at
any time upon written notice.  The term "Registrar" includes any co-Registrar.
The term "Paying Agent" includes any additional Paying Agent.  The Company
shall notify the Trustee of the name and address of any Agent not a party to





                                      -14-
<PAGE>   16
this Indenture.  If the Company fails to maintain a Registrar or Paying Agent,
the Trustee shall act as such.

SECTION 2.5.  Currency and Manner of Payments in Respect of Securities.

         (a)  With respect to Securities denominated in Dollars or Foreign
Currency and with respect to Registered Securities denominated in ECU with
respect to which the Holders of such Securities have not made the election
provided for in paragraph (b) below, the following payment provisions shall
apply:

                 (1)  Except as provided in subparagraph (a) (2) below, in
         paragraphs (e) and (j) below, in the applicable Company Notice, if
         any, or in the form or forms of any Series of Security, payment of the
         Principal of any Security will be made at the Place of Payment by
         delivery of a check in the currency in which the Security is
         denominated on the payment date against surrender of such Security,
         and any interest on any Security which is a Registered Security will
         be paid at the Place of Payment by mailing a check in the currency in
         which the Securities were issued to the Person entitled thereto at the
         address of such Person appearing on the Security register.  Unless
         otherwise provided in the Board Resolution establishing a Series or in
         the applicable Company Notice, if any, interest on any Security which
         is an Unregistered Security will be paid in the currency in which the
         Securities were issued in accordance with the provisions of
         subparagraph (c) below.

                 (2)  Payment of the Principal of and interest on such Security
         may also, subject to applicable laws and regulations, be made at such
         other place or places as may be designated by the Company by any
         appropriate method.

         (b)  With respect to Registered Securities denominated in ECU, the
following payment provisions shall apply, except as otherwise provided in
paragraphs (e) and (f) below:

                 (1)  The Board of Directors may provide that with respect to
         any Series of such Securities that Holders shall have the option to
         receive payments of Principal of and interest on such Security in any
         of the currencies which may be designated for such election in such
         Security by delivering to the Trustee and the Company a written
         election, to be in form and substance satisfactory to the Trustee and
         the Company, not later than the close of business on the record date
         immediately preceding the applicable payment date.  Such election will
         remain in effect for such Holder until changed by the Holder by
         written notice to the Trustee (but any such change must be made not
         later than the close of business on the record date immediately
         preceding the next payment date to be effective for the payment to be
         made on such payment date and no such change may be made with respect
         to payments to be made on any Security with respect to which notice of
         redemption has been given by the Company pursuant to Article Three).
         Any Holder of any such Security who shall not have delivered any such
         election to the Trustee not later than the close of business on the
         applicable record date will be paid the amount due on the applicable
         payment date in ECU as provided in paragraph (a) of this Section 2.5.
         Payment of Principal shall be made on the payment date against
         surrender of such Securities.  Payment of Principal and interest shall
         be made at the Place of Payment by mailing at such location a check in
         the applicable currency to the Person entitled thereto at the address
         of such Person appearing on the Security register.





                                      -15-
<PAGE>   17
                 (2)  Payment of the Principal of and interest on such Security
         may also, subject to applicable laws and regulations, be made at such
         other place or places as may be designated by the Company.

         (c)  To the extent provided in the Securities of a Series, (i)
interest, if any, on Unregistered Securities shall be paid only against
presentation and surrender of the coupons for such interest installments as are
evidenced thereby as they mature and (ii) original issue discount (as defined
in Section 1273 of the Internal Revenue Code of 1986 as it may be amended from
time to time), if any, on Unregistered Securities shall be paid only against
presentation and surrender of such Securities, in either case at the office of
a Paying Agent located outside of the United States, unless the Company shall
have otherwise instructed the Trustee in writing and only in the currency in
which the Security is denominated (except as provided in paragraph (e) below).
Principal of Unregistered Securities shall be paid only against presentation
and surrender thereof as provided in the Securities of a Series and only in the
currency in which the Security is denominated (except as provided in paragraph
(e) below, the Board Resolution establishing such Series, or the applicable
Company Notice, if any).  If at the time a payment of Principal or interest, if
any, or original issue discount, if any, on an Unregistered Security or coupon
shall become due, the payment of the full amount so payable at the office or
offices of all the Paying Agents is illegal or effectively precluded because of
the imposition of exchange controls or other similar restrictions on the
payment of such amount in Dollars or Foreign Currency, then the Company may
instruct the Trustee to make such payments at the office of a Paying Agent
located in the United States, provided that provision for such payment in the
United States would not cause such Unregistered Security to be treated as a
"registration-required obligation" under United States tax law and regulations.

         (d)  Not later than the fourth Business Day after the record date for
each payment date, the Trustee will deliver to the Company a written notice
specifying the aggregate amounts of Principal of and interest on the Securities
to be made on such payment date, specifying the amounts so payable in respect
of the Registered and the Unregistered Securities and the currencies or
currency units in which such payments are to be made.  If the Board of
Directors has provided for the election referred to in paragraph (b) above and
if at least one Holder has made such election, then not later than the eighth
Business Day following each record date the Company will deliver to the Trustee
an Exchange Rate Officer's Certificate in respect of the Dollar or Foreign
Currency payments to be made on such payment date.  The Dollar or Foreign
Currency amount receivable by Holders of Registered Securities denominated in
ECU who have elected payment in such currency as provided in paragraph (b)
above shall be determined by the Company on the basis of the applicable
Official ECU Exchange Rate set forth in the applicable Exchange Rate Officer's
Certificate.

         (e)  If the Foreign Currency in which any payments of Principal or
interest are to be made ceases to be used both by the government of the country
which issued such currency and for the settlement of transactions by public
institutions of or within the international banking community, or if the ECU
ceases to be used both within the European Monetary System and for the
settlement of transactions by public institutions of or within the European
Communities, then with respect to each date for the payment of Principal of and
interest on the applicable Securities occurring after the last date on which
the Foreign Currency or ECU was so used (the "Conversion Date"), the Dollar
shall be the currency of payment for use on each such payment date.  The Dollar
amount to be paid by the Company to the Trustee and by the Trustee or any
Paying Agent to the Holders of such Securities with respect to such payment
date shall be the Dollar Equivalent of the Foreign Currency or, in the





                                      -16-
<PAGE>   18
case of ECU, the Dollar Equivalent of the ECU as determined by the Trustee as
of the record date (the "Valuation Date") in the manner provided in paragraphs
(g) or (h) below.

         (f)  If the Holder of a Registered Security with respect to which
payments of Principal or interest are to be made in ECU elects payment in a
specified Foreign Currency as provided for by paragraph (b) and such Foreign
Currency ceases to be used both by the government of the country which issued
such currency and for the settlement of transactions by public institutions of
or within the international banking community, such Holder shall receive
payment in ECU, and if ECU ceases to be used both within the European Monetary
System and for the settlement of transactions by public institutions of or
within the European Communities, such Holder shall receive payment in Dollars.

         (g)  The "Dollar Equivalent of the Foreign Currency" shall be
determined by the Bank of Montreal--Foreign Exchange Desk as of each Valuation
Date and shall be obtained by converting the specified Foreign Currency into
Dollars at the Market Exchange Rate on the Valuation Date.

         (h)  The "Dollar Equivalent of the ECU" shall be determined by the
Bank of Montreal--Foreign Exchange Desk as of each Valuation Date and shall be
the sum obtained by adding together the results obtained by converting the
Specified Amount of each Component Currency into Dollars at the Market Exchange
Rate on the Valuation Date for such Component Currency.

         (i)  For purposes of this Section 2.5 the following terms shall have
the following meanings:

         A "Component Currency" shall mean any currency which, on the
Conversion Date, was a component currency of the ECU.

         A "Specified Amount" of a Component Currency shall mean the number of
units or fractions thereof which such Component Currency represented in the ECU
on the Conversion Date.  If after the Conversion Date the official unit of any
Component Currency is altered by way of combination or subdivision, the
Specified Amount of such Component Currency shall be divided or multiplied in
the same proportion.  If after the Conversion Date two or more Component
Currencies are consolidated into a single currency, the respective Specified
Amounts of such Component Currencies shall be replaced by an amount in such
single currency equal to the sum of the respective Specified Amounts of such
consolidated Component Currencies expressed in such single currency, and such
amount shall thereafter be a Specified Amount and such single currency shall
thereafter be a Component Currency.  If after the Conversion Date any Component
Currency shall be divided into two or more currencies, the Specified Amount of
such Component Currency shall be replaced by specified amounts of such two or
more currencies, the sum of which, at the Market Exchange Rate of such two or
more currencies on the date of such replacement, shall be equal to the
Specified Amount of such former Component Currency divided by the number of
currencies into which such Component Currency was divided, and such amounts
shall thereafter be Specified Amounts and such currencies shall thereafter be
Component Currencies.

         "Market Exchange Rate" shall mean for any currency the noon Dollar
buying rate for that currency for cable transfers quoted in New York City on
the Valuation Date as quoted by the Federal Reserve Bank of New York.  If such
rates are not available for any reason with respect to one or more currencies
for which an Exchange Rate is required, the Bank of Montreal--Foreign Exchange
Desk shall use, in its sole discretion and without liability on its part, such
quotation of the Federal Reserve Bank of New York as of the most recent
available date, or quotations from one or more





                                      -17-
<PAGE>   19
major banks in New York City or in the country of issue of the currency in
question, or such other quotations as the Trustee shall deem appropriate.
Unless otherwise specified by the Trustee, if there is more than one market for
dealing in any currency by reason of foreign exchange regulations or otherwise,
the market to be used in respect of such currency shall be that upon which a
nonresident issuer of securities designated in such currency would purchase
such currency in order to make payments in respect of such securities.

         All decisions and determinations of the Bank of Montreal--Foreign
Exchange Desk regarding the Dollar Equivalent of the Foreign Currency, the
Dollar Equivalent of the ECU and the Market Exchange Rate shall be in its sole
discretion and shall, in the absence of manifest error, be conclusive for all
purposes and irrevocably binding upon the Company and all Holders of the
Securities.  In the event that the Foreign Currency ceases to be used both by
the government of the country which issued such currency and for the settlement
of transactions by public institutions of or within the international banking
community, the Company, after learning thereof, will immediately give notice
thereof to the Trustee (and the Trustee will promptly thereafter give notice in
the manner provided in Section 10.2 to the Holders) specifying the Conversion
Date.  In the event the ECU ceases to be used both within the European Monetary
System and for the settlement of transactions by public institutions of or
within the European Communities, the Company, after learning thereof, will
immediately give notice thereof to the Trustee (and the Trustee will promptly
thereafter give notice in the manner provided in Section 10.2 to the Holders)
specifying the Conversion Date and the Specified Amount of each Component
Currency on the Conversion Date.  In the event of any subsequent change in any
Component Currency as set forth in the definition of Specified Amount above,
the Company, after learning thereof, will similarly give notice to the Trustee
(and the Trustee will promptly thereafter give notice in the manner provided in
Section 10.2 to the Holders).

         The Trustee shall be fully justified and protected in relying on and
acting upon the information so received by it from the Company and shall not
otherwise have any duty or obligation to determine such information
independently.

         (j)  Principal and interest payable on a Security represented by an
interest in a Temporary Global Security pursuant to Section 2.16 will not be
paid until the Holder thereof exchanges the appropriate portion of such
Temporary Global Security for an interest in the Permanent Global Security
except as provided in the next paragraph.

         Interest, if any, payable on a Security represented by a Temporary
Global Security in respect of an interest payment date occurring prior to the
Exchange Date will be paid to Euro-clear and CEDEL, as the case may be, with
respect to that portion of such Temporary Global Security held for its account;
provided, however, that no interest will be paid to Euroclear and CEDEL, as the
case may be, until delivery by it to the Trustee of a certificate in form and
substance acceptable to the Company, dated no earlier than such interest
payment date.  Such a certificate of Euro-clear or CEDEL, as the case may be,
shall be based on certificates of their Account Holders in form and substance
acceptable to the Company, and dated no earlier than 5 days prior to such
interest payment date.  The delivery to the Trustee by Euro- clear or CEDEL of
any such certificate may be relied upon by the Company and the Trustee as
conclusive evidence that a corresponding certificate or certificates has or
have been delivered to Euro-clear or CEDEL, as the case may be, pursuant to the
terms of this Indenture.  Each of Euro-clear or CEDEL will in such
circumstances credit the interest received by it in respect of such Security
represented by such Temporary Global Security to the accounts of or for the
beneficial owners thereof.





                                      -18-
<PAGE>   20
         The Permanent Global Securities will provide that interest, if any,
payable in respect of any interest payment date will be paid to each of
Euro-clear and CEDEL with respect to that portion of such Permanent Global
Security held for its account.  Each of Euro-clear and CEDEL will in such
circumstances credit the interest received by it in respect of such Permanent
Global Security to the accounts of or for the beneficial owners thereof.

         Interest, if any, will be payable in respect of Definitive Securities
upon the presentation and surrender of the appropriate coupons appertaining
thereto.

         (k)  Notwithstanding anything contained herein to the contrary, any
payment of principal of or interest on any Security may be made in the manner
specified on the form of such Security.

SECTION 2.6.  Paying Agent to Hold Money in Trust.

         The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust, for the benefit of
Securityholders of any or all Series of Securities, or the Trustee, all money
held by the Paying Agent for the payment of principal of or interest on such
Series of Securities, and that the Paying Agent will notify the Trustee of any
default by the Company in the making of any such payment.  While any such
default continues, the Trustee may require a Paying Agent to pay all money held
by it to the Trustee.  If the Company or a subsidiary thereof acts as Paying
Agent, it shall segregate the money held by it for the payment of principal or
interest on any Series of Securities and hold such money as a separate trust
fund.  The Company at any time may require a Paying Agent to pay all money held
by it to the Trustee.  Upon so doing the Paying Agent shall have no further
liability for the money so paid.

SECTION 2.7.  Securityholder Lists; Ownership of Securities.

         (a)  The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders of each Series of Securities.  If the Trustee is not the Registrar, the
Company shall furnish to the Trustee semiannually on or before the last day of
June and December in each year, and at such other times as the Trustee may
request in writing, a list, in such form and as of such date as the Trustee may
reasonably require, containing all the information in the possession or control
of the Registrar, the Company or any of its Paying Agents other than the
Trustee as to the names and addresses of Holders of each such Series of
Securities.  If there are Unregistered Securities of any Series outstanding,
even if the Trustee is the Registrar, the Company shall furnish to the Trustee
such a list containing such information with respect to Holders of such
Unregistered Securities only.

         (b)  Ownership of Registered Securities of a Series shall be proved by
the register for such Series kept by the Registrar.  Ownership of Unregistered
Securities may be proved by the production of such Unregistered Securities or
by a certificate or affidavit executed by the person holding such Unregistered
Securities or by a depositary with whom such Unregistered Securities were
deposited, if the certificate or affidavit is satisfactory to the Trustee.  The
Company, the Trustee and any agent of the Company may treat the bearer of any
Unregistered Security or coupon and the person in whose name a Registered
Security is registered as the absolute owner thereof for all purposes.





                                      -19-
<PAGE>   21
SECTION 2.8.  Transfer and Exchange.

         (a)  Where Registered Securities of a Series are presented to the
Registrar with a request to register their transfer or to exchange them for an
equal principal amount of Registered Securities of the same Series and date of
maturity of other authorized denominations, the Registrar shall, unless
otherwise restricted by the provisions of Section 2.15, register the transfer
or make the exchange if its customary requirements for such transactions are
met.

         (b)  If both Registered and Unregistered Securities are authorized for
a Series of Securities and the terms of such Securities permit, (i)
Unregistered Securities may be exchanged for an equal principal amount of
Registered or Unregistered Securities of the same Series and date of maturity
in any authorized denominations upon delivery to the Registrar (or a Paying
Agent, if the exchange is for Unregistered Securities) of the Unregistered
Security with all unmatured coupons and all matured coupons in default
appertaining thereto and if all other requirements of the Registrar (or such
Paying Agent) and such Securities for such exchange are met, and (ii)
Registered Securities may be exchanged for an equal principal amount of
Unregistered Securities of the same Series and date of maturity in any
authorized denominations (except that any coupons appertaining to such
Unregistered Securities which have matured and have been paid shall be
detached) upon delivery to the Registrar of the Registered Securities and if
all other requirements of the Registrar (or such Paying Agent) and such
Securities for such exchange are met.

         Notwithstanding the foregoing, the exchange of Unregistered Securities
for Registered Securities or Registered Securities for Unregistered Securities
will be subject to the satisfaction of the provisions of United States laws and
regulations in effect at the time of such exchange, and no exchange of
Registered Securities for Unregistered Securities will be made until the
Company has notified the Trustee and the Registrar that, as a result of such
exchange, the Company would not suffer adverse consequences under such law or
regulations.

         (c)  To permit registrations of transfers and exchanges, the Trustee
shall, unless otherwise restricted by the provisions of Section 2.15,
authenticate Securities upon surrender of Securities for registration of
transfer or for exchange as provided in this Section.  The Company will make
any charge for any registration of transfer or exchange but may require the
payment by the party requesting such registration of transfer exchange of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith, but not for any exchange pursuant to Section 2.12, 3.6 or 9.5.

         (d)  Neither the Company nor the Registrar shall be required (i) to
issue, register the transfer of or exchange Securities of any Series for the
period of 15 days immediately preceding the selection of any such Securities to
be redeemed and ending at the close of business on the first publication of the
relevant notice of redemption, or (ii) to register the transfer of or exchange
Securities of any Series selected, called or being called for redemption as a
whole or the portion being redeemed of any such Securities selected, called or
being called for redemption in part.

         (e)  Notwithstanding the foregoing, no Securities of one Tranche may
be transferred or exchanged for Securities of any other Tranche.

         (f)  Unregistered Securities or any coupons appertaining thereto shall
be transferable by delivery.





                                      -20-
<PAGE>   22
SECTION 2.9.  Replacement Securities.

         (a)  If a mutilated Security or a Security with a mutilated coupon
appertaining to it is surrendered to the Trustee, the Company shall issue and
the Trustee shall authenticate and deliver in exchange therefor a replacement
Registered Security, if such surrendered security was a Registered Security, or
a replacement Unregistered Security with coupons corresponding to the coupons
appertaining to the surrendered Security, if such surrendered Security was an
Unregistered Security, of the same Series and date of maturity, if the
Trustee's requirements are met.

         (b)  If the Holder of a Security claims that the Security or any
coupon appertaining thereto has been lost, destroyed or wrongfully taken, the
Company shall issue and the Trustee shall authenticate a replacement Registered
Security, if such Holder's claim pertains to a Registered Security, or a
replacement Unregistered Security with coupons corresponding to the coupons
appertaining to the lost, destroyed or wrongfully taken Unregistered Security
or the Unregistered Security to which such lost, destroyed or wrongfully taken
coupon appertains, if such Holder's claim pertains to an Unregistered Security,
of the same Series and date of maturity, if the Trustee's requirements are met;
provided, however, that the Holder shall furnish to the Company and to the
Trustee evidence to their satisfaction of the destruction, loss or theft of
such Security and of the ownership thereof, and that the Trustee or the Company
may require any such Holder to provide to the Trustee or the Company security
or indemnity sufficient in the judgment of the Company and the Trustee to
protect the Company, the Trustee, any Agent or any Authenticating Agent from
any loss which any of them may suffer if a Security is replaced.  The Company
and the Trustee may charge the party requesting a replacement Security for its
expenses in replacing a Security.

         (c)  In case any Security which has matured or is about to mature
shall become mutilated or be destroyed, lost or stolen, the Company may,
instead of issuing a substitute Security, pay or authorize the payment of such
Security (without surrender thereof except in the case of a mutilated Security)
if the applicant for such payment shall furnish to the Company such security or
indemnity as it may require to save it harmless and, in case of destruction,
loss or theft, evidence to the satisfaction of the Company of the destruction,
loss or theft of such Security and of the ownership thereof.

         (d)  Every substituted Security issued pursuant to the provisions of
this Section 2.9 by virtue of the fact that any Security is mutilated,
destroyed, lost or stolen shall, with respect to such Security, constitute an
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall at any time be enforceable by anyone, and shall
be entitled to all the benefits of this Indenture equally and proportionately
with any and all other Securities duly issued under this Indenture.  All
Securities shall be held and owned upon the express condition that (to the
extent lawful) the foregoing provisions shall be 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 now existing or hereafter enacted to the contrary with respect to the
replacement or payment of negotiable instruments or other securities without
their surrender.

         (e)  Notwithstanding the foregoing, a Security of one Tranche may not
be replaced with a Security of any other Tranche.

SECTION 2.10.  Outstanding Securities.

         (a)  Securities outstanding at any time are all Securities
authenticated and delivered by the Trustee in accordance with the provisions of
this Indenture, except:

         (i)  Those cancelled by the Trustee and those delivered to it for
cancellation;

         (ii)  Securities which have been paid pursuant to Section 2.9 or in
exchange for or in lieu of which other Securities have been authenticated and
delivered pursuant to this Indenture, unless proof satisfactory to the Trustee
is presented that any such Securities are held by bona fide Holders in due
course; and

         (iii)  Securities or portions thereof for whose payment, redemption or
repayment at the option of the Holder money in the necessary amount has been
theretofore deposited with the Trustee or any Paying Agent (as defined in
Section 2.4) (other than the Company) in trust or set aside and segregated in
trust by the Company (if the Company shall act as its own Paying Agent) for the
Holders of such Securities; provided that, if such Securities or portions
thereof are to be redeemed, notice of such redemption has been duly given
pursuant to this Indenture or provision therefor satisfactory to the Trustee
has been made.

         (b)  A Security does not cease to be outstanding because the Company
or an Affiliate holds the Security.

         (c)  In determining whether the Holders of the requisite principal
amount of outstanding Securities of any Series have given any request, demand,
authorization, direction, notice, consent or waiver hereunder, or whether
sufficient funds are available for redemption or for any other purpose, the
principal amount of an Original Issue Discount Security that shall be deemed to
be outstanding for such purposes shall be the amount of the principal thereof
that would be due and payable as of the date of such determination upon a
declaration of acceleration of the maturity thereof pursuant to Section 6.2 or
6.3 and the principal amount of any Securities denominated in a Foreign
Currency or ECU that shall be deemed to be outstanding for such purposes shall
be determined by converting the Specified Foreign Currency or the Specified
Amount of each Component Currency into Dollars at the Market Exchange Rate as
of the date of such determination.

SECTION 2.11.  Securities Held by the Company or an Affiliate.

         In determining whether the Holders of the requisite principal amount
of Securities of any Series have concurred in any direction, waiver or consent,
Securities of such Series owned by the Company or an Affiliate shall be
disregarded, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Securities of such Series which the Trustee knows are so owned shall be so
disregarded.

SECTION 2.12.  Temporary Securities.

         (a)  Until definitive Registered Securities of any Series are ready
for delivery, the Company may prepare and execute and the Trustee shall
authenticate temporary Registered Securities of such Series.  Temporary
Registered Securities of any Series shall be substantially in the form of
definitive Registered Securities of such Series but may have variations that
the Company considers appropriate





                                      -22-
<PAGE>   24
for temporary Securities.  Every temporary Registered Security shall be
executed by the Company and authenticated by the Trustee, and registered by the
Registrar, upon the same conditions, and with like effect, as a definitive
Registered Security.  Without unreasonable delay, the Company shall prepare and
the Trustee shall authenticate definitive Registered Securities of the same
Series and date of maturity in exchange for temporary Registered Securities.

         (b)  Until definitive Unregistered Securities of any Series are ready
for delivery, the Company may prepare and execute and the Trustee shall
authenticate one or more temporary Unregistered Securities, which may have
coupons attached or which may be in the form of a single temporary global
Unregistered Security of that Series without coupons.  The temporary
Unregistered Security or Securities of any Series shall be substantially in the
form approved by or pursuant to a Board Resolution or one or more Indentures
supplemental hereto and shall be delivered to one of the Paying Agents located
outside the United States or to such other person or persons as the Company
shall direct against such certification as the Company may from time to time
prescribe by or pursuant to a Board Resolution.  The temporary Unregistered
Security or Securities of a Series shall be executed by the Company and
authenticated by the Trustee upon the same conditions, and with like effect, as
a definitive Unregistered Security of such Series, except as provided herein or
therein.  A temporary Unregistered Security or Securities shall be exchangeable
for definitive Unregistered Securities (which may be Global Securities), at the
time and on the conditions, if any, specified in the temporary Security.

         Upon any exchange of a part of a temporary Unregistered Security of a
Series for definitive Unregistered Securities of such Series, the temporary
Unregistered Security shall be endorsed by the Trustee or Paying Agent to
reflect the reduction of its principal amount by an amount equal to the
aggregate principal amount of definitive Unregistered Securities of such Series
so exchanged and endorsed.

SECTION 2.13.  Cancellation.

         The Company at any time may deliver Securities and coupons to the
Trustee for cancellation.  The Registrar and the Paying Agent shall forward to
the Trustee any Securities and coupons surrendered to them, for registration of
transfer, for exchange or payment or for credit against any payment in respect
of a sinking or analogous fund.  The Trustee shall cancel all Securities and
coupons surrendered for registration of transfer, or for exchange, payment or
cancellation and may dispose of cancelled Securities and coupons as the Company
directs; provided, however, that any Unregistered Securities of a Series
delivered to the Trustee for exchange prior to maturity shall be retained by
the Trustee for reissue as provided herein or in the Securities of such Series.
The Company may not issue new Securities to replace Securities that it has paid
or delivered to the Trustee for cancellation.

SECTION 2.14.  Defaulted Interest.

         If the Company defaults on a payment of interest on a Series of
Securities, it shall pay the defaulted interest as provided in such Securities
or in any lawful manner not inconsistent with the requirements of any
securities exchange on which such Securities may be listed and acceptable to
the Trustee.  With respect to any Registered Securities, the Trustee may pay
defaulted interest, plus any interest payable on the defaulted interest, to the
Holders of such Registered Securities on a subsequent special record date.  The
Company shall fix the record date and the payment date.  At least 15 days





                                      -23-
<PAGE>   25
before the record date, the Company shall mail to such Holders a notice that
states the record date, the payment date and the amount of interest to be paid.

SECTION 2.15.  Securities Issuable in the Form of a Global Security.

         (a)  If the Company shall establish pursuant to Section 2.2 that the
Securities of a particular Series are to be issued as one or more Global
Securities, then the Company shall execute and the Trustee shall, in accordance
with Section 2.3 and the Company Order delivered to the Trustee thereunder,
authenticate and deliver one or more Global Securities which (i) shall
represent, and shall be denominated in an amount equal to the aggregate
principal amount of, all of the Outstanding Securities of such Series, (ii)
shall be registered in the name of the Depositary for such Global Security or
its nominee, (iii) shall be delivered by the Trustee to the Depositary or
pursuant to the Depositary's instruction and (iv) shall bear a legend
substantially to the following effect: "Except as otherwise provided in Section
2.15 of the Indenture, this Security may be transferred, in whole but not in
part, only to another nominee of the Depositary or to a successor Depositary or
to a nominee of such successor Depositary."

         (b)  Notwithstanding any other provision of this Section 2.15 or of
Section 2.4, unless and until it is exchanged in whole or in part for
Securities in definitive form, the Global Security of a Series may be
transferred, in whole but not in part and in the manner provided in Section
2.4, to another nominee of the Depositary for such Series, or to a successor
Depositary for such Series selected or approved by the Company or to a nominee
of such successor Depositary.

         (c)  If at any time the Depositary for a Series of Securities notifies
the Company that it is unwilling or unable to continue as Depositary for such
Series or if at any time the Depositary for such Series shall no longer be
registered or in good standing under the Securities Exchange Act of 1934, as
amended, or other applicable statute or regulation and a successor Depositary
for such Series is not appointed by the Company within 90 days after the
Company receives such notice or becomes aware of such condition, as the case
may be, this Section 2.15 shall no longer be applicable to the Security of such
Series and the Company will execute, and the Trustee will authenticate and
deliver, Securities of such Series in definitive registered form without
coupons, or in definitive bearer form with coupons, as applicable, in
authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Security of such Series in exchange for such
Global Security.  In addition, the Company may at any time determine that some
or all of the Securities of any Series shall no longer be represented by a
Global Security.  In such event, the Company will execute and the Trustee, upon
receipt of an Officers' Certificate evidencing such determination by the
Company, will authenticate and deliver Securities of such Series in definitive
form, in authorized denominations, to (i) the Person specified by such
Depositary equal to and in 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
definitive Securities delivered to Holders thereof, or interests in applicable
portions thereof.  Upon the exchange of the Global Security for all such
Securities in definitive form, in authorized denominations, the surrendered
Global Security shall be cancelled by the Trustee.  Such Securities in
definitive registered form issued in exchange for the Global Security or
portion thereof pursuant to this Section 2.15(c) shall be issued in such
authorized denominations as the Depositary, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the Trustee.  The
Trustee shall deliver such Securities to the Persons in whose name such
Securities are so registered.  Securities in definitive bearer form shall be
issued in exchange for the





                                      -24-
<PAGE>   26
Global Security or portion thereof in the manner provided for the issuance of
Unregistered Securities in Section 2.12(b) above.

SECTION 2.16.  Unregistered Securities Represented by Global Security.

         (a)  Unless otherwise specified by the applicable Company Order, the
Securities of any Series issued as Unregistered Securities will initially be
represented by one or more temporary global Securities, without interest
coupons (each, a "Temporary Global Security").  Upon receipt of a Company Order
with respect to a Series of Securities, the Trustee, in accordance with such
Company Order, shall (1) insert on the face of the Temporary Global Security
for such Series (a) the principal amount, (b) the issue date, (c) the maturity
date, (d) the interest rate or the method of determining such rate, and (e) any
other terms required by the form of the Security of such Series to be inserted,
as specified in the Company Order, (2) manually authenticate such Temporary
Global Security and (3) deliver such Temporary Global Security to the
Depositary designated by the Company pursuant to either Sections 2.2 or 2.15.

         (b)  On or after the date which is 45 days after the issue date of a
Temporary Global Security (the "Exchange Date"), the Securities represented by
such Temporary Global Security may be exchanged for Securities to be
represented thereafter by a single permanent global Security, without interest
coupons (a "Permanent Global Security"), provided, however, that no Security
represented by a Temporary Global Security shall be exchanged for a Security
represented by a Permanent Global Security unless the Trustee shall have
received a certificate (a "Final Certificate"), in form and substance
reasonably satisfactory to the Company, signed by Euro-clear or CEDEL, as the
case may be, in respect of such Security.  On or after the Exchange Date and
upon receipt of the Final Certificate in respect of a Security, dated no
earlier than such Exchange Date, the Trustee shall (1) endorse the Temporary
Global Security to reflect the reduction of its principal amount by the
aggregate principal amount of such Security, (2) insert on the face of the
Permanent Global Security for such Series (a) the principal amount, (b) the
issue date, (c) the maturity date, (d) the interest rate or method of
determining such rate, and (e) any other terms required by the form of the
Security of such Series to be inserted, as set forth on the face of the
Temporary Global Security for such Series, (3) manually authenticate such
Permanent Global Security and (4) deliver such Permanent Global Security to the
Depositary to be held outside the United States for the accounts of Euro-clear
and CEDEL, for credit to the respective accounts at Euro-clear and CEDEL
designated by or on behalf of the beneficial owner of such Security.  Final
Certificates of Euro-clear or CEDEL, as the case may be, shall be based on
certificates of the account holders listed in the records of Euro-clear or
CEDEL, as the case may be, as being entitled to all or any portion of the
applicable Temporary Global Security (as to each, its "Account Holder").  An
Account Holder of Euro-clear or CEDEL, as the case may be, desiring to effect
the exchange of an interest in a Temporary Global Security for an interest in a
Permanent Global Security shall instruct Euro-clear or CEDEL, as the case may
be, to request such exchange on its behalf and shall deliver to Euro-clear or
CEDEL, as the case may be, a certificate in form and substance reasonably
satisfactory to Euro-clear or CEDEL, as applicable, and dated no earlier than
10 days prior to the Exchange Date.  Until so exchanged, Temporary Global
Securities shall in all respects be entitled to the same benefits under this
Indenture as Permanent Global Securities of the same Series authenticated and
delivered hereunder, except as to payment of interest, if any.

         (c)  The delivery to the Trustee by Euro-clear or CEDEL of any Final
Certificate referred to above may be relied upon by the Company and the Trustee
as conclusive evidence that a





                                      -25-
<PAGE>   27
corresponding certificate or certificates has or have been delivered to
Euro-clear or to CEDEL, as the case may be, pursuant to the terms of this
Indenture.

         (d)  At any time, upon 30 days' notice to the Trustee by Euro-clear or
CEDEL, as the case may be, acting at the request of or on behalf of the
beneficial owner, a Security represented by a Permanent Global Security may be
exchanged for a definitive Security or Securities (each a "Definitive
Security").  On the thirtieth day following receipt by the Trustee of such
notice with respect to a Security, or, if such day is not a Business Day, the
next succeeding Business Day, the Trustee shall (1) endorse the applicable
Permanent Global Security to reflect the reduction of its principal amount by
the aggregate principal amount of such Security, (2) cause the terms of such
Security and coupons, if any, to be entered on a Definitive Security, (3)
manually authenticate such Definitive Security, and (4) deliver such Definitive
Security outside the United States to Euro-clear or CEDEL, as the case may be,
for or on behalf of the beneficial owner thereof.

         (e)  Any exchange of a portion of a Temporary Global Security for a
portion of a Permanent Global Security or of a portion of a Permanent Global
Security for a Definitive Security with coupons, if any, shall be made at the
Company's expense and without any charge therefor to the Holder or beneficial
owner of such Security; provided, however, that a person accepting the delivery
of Definitive Securities with coupons, if any, must bear the risk and cost of
insurance, postage, transportation and the like in the event that such person
does not receive such Definitive Securities with coupons, if any, in person at
the London office of the Trustee, if any, or at the London office of any Paying
Agent.  Until so exchanged, Temporary Global Securities and Permanent Global
Securities shall in all respects be entitled to the same benefits under this
Indenture as Definitive Securities of the same Series authenticated and
delivered hereunder.

         (f)  The provisions of this Section are subject to any restrictions or
limitations on the issuance and delivery of Securities of any Series that may
be established pursuant to Section 2.2 (including any provision that Securities
of such Series initially issued in the form of a Temporary Global Security to
be delivered outside the United States and the procedures pursuant to which a
Permanent Global Security or Definitive Securities of such Series would be
issued in exchange for a Temporary Global Security.)

         (g)  If the form or terms of the Securities of a Series have been
established in or pursuant to one or more Board Resolutions as permitted by
Section 2.2, in authenticating such Securities and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and shall be fully protected in relying
upon, an Opinion of Counsel stating:

                 (i)  if the form of such Securities and coupons, if any,
         appertaining thereto has been established by or pursuant to a Board
         Resolution as permitted by Section 2.2, that such form has been
         established in conformity with the provisions of this Indenture;

                 (ii)  if the terms of such Securities and coupons, if any,
         appertaining thereto have been established by or pursuant to a Board
         Resolution as permitted by Section 2.2, that such terms have been
         established in conformity with the provisions of this Indenture; and

                 (iii)  that such Securities and coupons, if any, appertaining
         thereto, when authenticated and delivered by the Trustee and issued by
         the Company in the manner and subject to any





                                      -26-
<PAGE>   28
         conditions specified in such Opinion of Counsel, will constitute valid
         and legally binding obligations of the Company, enforceable in
         accordance with their terms, subject, as to enforcement, to
         bankruptcy, insolvency, reorganization, moratorium and other laws of
         general applicability relating to or affecting the enforcement of
         creditors' rights and to general equity principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issuance of such Securities
pursuant to this Indenture shall affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.


                                  ARTICLE III

                   REDEMPTION OF SECURITIES AND SINKING FUNDS

SECTION 3.1.  Notice to Trustee.

         The Company may, with respect to any Series of Securities, reserve the
right to redeem and pay the Series of Securities or any part thereof, or may
covenant to redeem and pay the Series of Securities or any part thereof, before
maturity at such time and on such terms as provided for in such Securities.  If
a Series of Securities is redeemable and the Company wants or is obligated to
redeem all or part of the Series of Securities pursuant to the terms of such
Securities, it shall notify the Trustee of the redemption date and the
principal amount of the Series of Securities to be redeemed.  The Company shall
give such notice at least 60 days before the redemption date (or such shorter
notice as may be acceptable to the Trustee).

SECTION 3.2.  Selection of Securities to be Redeemed.

         If less than all the Securities of a Series are to be redeemed, the
Trustee, not more than 60 days prior to the redemption date, shall select the
Securities of the Series to be redeemed in such manner as the Trustee shall
deem fair and appropriate.  The Trustee shall make the selection from
Securities of the Series that are outstanding and that have not previously been
called for redemption.  Securities of the Series and portions of them selected
by the Trustee shall be in amounts of $1,000 or integral multiples of $1,000
or, with respect to Securities of any Series issuable in other denominations
pursuant to Section 2.2 (a) (8), in amounts equal to the minimum principal
denomination for each such Series and integral multiples thereof.  Provisions
of this Indenture that apply to Securities of a Series called for redemption
also apply to portions of Securities of that Series called for redemption.  The
Trustee shall promptly notify the Company in writing of the Securities selected
for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed.

SECTION 3.3.  Notice of Redemption.

         (a)  At least 30 days but not more than 60 days before a redemption
date, the Company shall mail a notice of redemption by first-class mail to each
Holder of Registered Securities that are to be redeemed.





                                      -27-
<PAGE>   29
         (b)  If Unregistered Securities are to be redeemed, the Company shall
cause notice of redemption to be published in an Authorized Newspaper in each
of The City of New York, London and, if such Securities to be redeemed are
listed on The Luxembourg Stock Exchange, Luxembourg once in each of four
successive calendar weeks, the first publication to be not less than 30 nor
more than 60 days before the redemption date.

         (c)  All notices shall identify the Series of Securities to be
redeemed and shall state:

                 (1)  the redemption date;

                 (2)  the redemption price;

                 (3)  if less than all the outstanding Securities of a Series
         are to be redeemed, the identification (and, in the case of partial 
         redemption, the principal amounts) of the particular Securities to be
         redeemed;

                 (4)  in case any Security is to be redeemed in part only, the
         notice 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 presentation and surrender of such Security, a new
         Security or Securities in principal amount equal to the unredeemed
         portion thereof will be issued;

                 (5)  the name and address of the Paying Agent;

                 (6)  that Securities of the Series called for redemption and 
         all unmatured coupons, if any, appertaining thereto must be 
         surrendered to the Paying Agent to collect the redemption price;

                 (7)  that interest on Securities of the Series called for
         redemption ceases to accrue on and after the redemption date;

                 (8)  whether such redemption is pursuant to the mandatory or
         optional sinking fund, or both; and

                 (9)  the CUSIP Number, if applicable.

         At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense.  Any notice which is
mailed in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not the Holder receives the notice.  In any case,
failure duly to give notice by mail, or any defect in the notice, to the Holder
of any Security designated for redemption as a whole or in part shall not
affect the validity of the proceedings for the redemption of any other
Security.

SECTION 3.4.  Effect of Notice of Redemption.

         Once notice of redemption is mailed or published, Securities of a
Series called for redemption become due and payable on the redemption date, and
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 the Securities so called for redemption shall cease
to accrue on and after said





                                      -28-
<PAGE>   30
date.  Upon surrender to the Paying Agent of such Securities together with all
unmatured coupons, if any, appertaining thereto, such Securities shall be paid
at the redemption price plus interest accrued to the redemption date, but
installments of interest due on or prior to the redemption date will be
payable, in the case of Unregistered Securities, to the bearers of the coupons
for such interest upon surrender thereof, and, in the case of Registered
Securities, to the Holders of such Securities of record at the close of
business on the relevant record dates.

SECTION 3.5.  Deposit of Redemption Price.

         On or before the redemption date, the Company shall deposit with, or
at the direction of, the Trustee money sufficient to pay the redemption price
of and (unless the redemption date shall be an interest payment date) interest
accrued to the redemption date on all Securities to be redeemed on that date,
in the currencies or currency units in which such redemption price shall be
payable.

SECTION 3.6.  Securities Redeemed in Part.

         Upon surrender of a Security that is redeemed in part, the Company
shall issue and the Trustee shall authenticate for the Holder of the Security a
new Security or Securities of the same Series, in the same form and the same
maturity in authorized denominations equal in aggregate Principal amount to the
unredeemed portion of the Security surrendered.

SECTION 3.7.  Securities Acquired by the Company.

         If the Company shall acquire any of the Securities or coupons, such
acquisition shall not operate as a redemption or satisfaction of the
indebtedness or rights represented by such Securities or coupons unless and
until the same are delivered or surrendered to the Trustee for cancellation.

SECTION 3.8.  Mandatory and Optional Sinking Funds.

         The minimum amount of any sinking fund payment provided for by the
terms of any Series of Securities 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 any Series of Securities is herein referred to as an "optional
sinking fund payment." The date on which a sinking fund payment is to be made
is herein referred to as the "sinking fund payment date."

         In lieu of making all or any part of any mandatory sinking fund
payment with respect to any Series of Securities in cash, the Company may at
its option (a) deliver to the Trustee Securities of such Series theretofore
purchased or otherwise acquired (except upon redemption pursuant to the
mandatory sinking fund) by the Company or receive credit for Securities of such
Series (not previously so credited) theretofore purchased or otherwise acquired
(except as aforesaid) by the Company and delivered to the Trustee for
cancellation pursuant to Section 2.13, (b) receive credit for optional sinking
fund payments (not previously so credited) made pursuant to this Section, or
(c) receive credit for Securities of such Series (not previously so credited)
redeemed by the Company through any optional redemption provision contained in
the terms of such Series.  Securities so delivered or credited shall be
received or credited by the Trustee at the sinking fund redemption price
specified in such Securities.





                                      -29-
<PAGE>   31
         On or before the sixtieth day next preceding each sinking fund payment
date for any Series, the Company will deliver to the Trustee an Officers'
Certificate (a) specifying the portion of the mandatory sinking fund payment to
be satisfied by payment of cash and the portion to be satisfied by credit of
Securities of such Series, (b) stating that none of the Securities of such
Series has theretofore been so credited, (c) stating that no defaults in the
payment of interest or Events of Default with respect to such Series have
occurred (which have not been waived or cured) and are continuing, (d) stating
whether or not the Company intends to exercise its right to make an optional
sinking fund payment with respect to such Series and, if so, specifying the
amount of such optional sinking fund payment which the Company intends to pay
on or before the next succeeding sinking fund payment date and (e) specifying
such sinking fund payment date.  Any Securities of such Series to be credited
and required to be delivered to the Trustee in order for the Company to be
entitled to credit therefor as aforesaid which have not theretofore been
delivered to the Trustee shall be delivered for cancellation pursuant to
Section 2.13 to the Trustee with such written statement (or reasonably promptly
thereafter if acceptable to the Trustee).  Such written statement shall be
irrevocable and upon its receipt by the Trustee the Company shall become
unconditionally obligated to make all the cash payment or payments therein
referred to, if any, on or before the next succeeding sinking fund payment
date.  Failure of the Company, on or before any such sixtieth day, to deliver
such written statement and Securities specified in this paragraph, if any,
shall not constitute a default but shall constitute, on and as of such date,
the irrevocable election of the Company (i) that the mandatory sinking fund
payment for such Series due on the next succeeding sinking fund payment date
shall be paid entirely in cash without the option to deliver or credit
Securities of such Series in respect thereof and (ii) that the Company will
make no optional sinking fund payment with respect to such Series as provided
in this Section.

         If the sinking fund payment or payments (mandatory or optional or
both) to be made in cash on the next succeeding sinking fund payment date 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, such cash shall be applied 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.  If such amount shall be $50,000 or less and
the Company makes no such request then it shall be carried over until a sum in
excess of $50,000 is available.  The Trustee shall select, in the manner
provided in Section 3.2, 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 possible, and shall (if requested in writing by the
Company) inform the Company of the serial numbers of the Securities of such
Series (or portions thereof) so selected.  Securities of any Series which are
(a) owned by the Company or an entity known by the Trustee to be directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company, as shown by the Security register, and not known to
the Trustee to have been pledged or hypothecated by the Company or any such
entity or (b) identified in an Officers' Certificate at least 60 days prior to
the sinking fund payment date as being beneficially owned by, and not pledged
or hypothecated by, the Company or an entity directly or indirectly controlling
or controlled by or under direct or indirect common control with the Company
shall be excluded from Securities of such Series eligible for selection for
redemption.  The Trustee, in the name and at the expense of the Company (or the
Company, if it shall so request the Trustee in writing) shall cause notice of
redemption of the Securities of such Series to be given in substantially the
manner provided in Section 3.3 (and with the effect provided in Section 3.4)
for the redemption of Securities of such Series in part at the option of the
Company.  The amount of any sinking fund payments not so applied or allocated
to the redemption of Securities of such Series shall be added to





                                      -30-
<PAGE>   32
the next cash sinking fund payment for such Series and, together with such
payment, shall be applied in accordance with the provisions of this Section.
Any and all sinking fund moneys held on the stated maturity date of the
Securities of any particular Series (or earlier, if such maturity is
accelerated), which are not held for the payment or redemption of particular
Securities of such Series shall be applied, together with other moneys, if
necessary, sufficient for the purpose, to the payment of the Principal of, and
interest on, the Securities of such Series at maturity.

         At least one Business Day before each sinking fund payment date, the
Company shall pay to the Trustee in cash or shall otherwise provide for the
payment of all interest accrued to the date fixed for redemption on Securities
to be redeemed on the next following sinking fund payment date.

         The Trustee shall not redeem or cause to be redeemed any Securities of
a Series with sinking fund moneys or mail any notice of redemption of
Securities for 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 except that, where the mailing of notice of redemption of any
Securities shall theretofore have been made, the Trustee shall redeem or cause
to be redeemed such Securities, provided that it shall have received from the
Company a sum sufficient for such redemption.  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 such sinking fund,
shall, during the continuance of such Default or Event of Default, be deemed to
have been collected under Article Six and held for the payment of all such
Securities.  In case such Event of Default shall have been waived as provided
in Section 6.4 or the default cured on or before the sixtieth day preceding the
sinking fund payment date in any year, such moneys shall thereafter be applied
on the next succeeding sinking fund payment date in accordance with this
Section to the redemption of such Securities.

                             DEFAULTS AND REMEDIES

SECTION 6.1.  Events of Default.

         An "Event of Default" occurs with respect to the Securities of any
Series if:

                 (1)  the Company defaults in the payment of interest on any
         Security of that Series when the same becomes due and payable and the
         Default continues for a period of 30 days;

                 (2)  the Company defaults in the payment of the Principal of
         any Security of that Series when the same becomes due and payable at
         maturity, upon redemption or otherwise;

                 (3)  the Company defaults in the payment of any sinking fund
         installment as and when the same becomes due and payable by the terms
         of the Series of Securities;

                 (4)  the Company fails to comply with any of its other
         agreements in the Securities of that Series, in this Indenture or in
         any supplemental indenture under which the Securities of that Series
         may have been issued and the Default continues for the period and
         after the notice specified below;





                                      -33-
<PAGE>   35
                 (5)  the Company pursuant to or within the meaning of any
                      Bankruptcy Law:

                          (A)  commences a voluntary case,

                          (B)  consents to the entry of an order for relief 
                 against it in an involuntary case,

                          (C)  consents to the appointment of a Custodian of it
                 or for all or substantially all of its property, or

                          (D)  makes a general assignment for the benefit of 
                 its creditors; or

                 (6)  a court of competent jurisdiction enters an order or 
         decree under any Bankruptcy Law that:

                          (A)  is for relief against the Company in an
                 involuntary case,

                          (B)  appoints a Custodian of the Company or for all 
                 or substantially all of its property, or

                          (C)  orders the liquidation of the Company, and the
                 order or decree remains unstayed and in effect for 90 days.

         The term "Bankruptcy Law" means Title 11, U.S. Code or any similar
federal or state law for the relief of debtors.  The term "Custodian" means any
receiver, trustee, assignee, liquidator or similar official under any
Bankruptcy Law.

         A Default under clause (4) is not an Event of Default until the
Trustee or the Holders of at least 25% in principal amount of all the
outstanding Securities of that Series notify the Company (and the Trustee in
the case of notification by such Holders) in writing of the Default and the
Company does not cure the Default within 90 days after receipt of the notice.
The notice must specify the Default, demand that it be remedied and state that
the notice is a "Notice of Default".

SECTION 6.2.  Acceleration.

         If an Event of Default occurs with respect to the Securities of any
Series and is continuing, the Trustee, by notice to the Company, or the Holders
of at least 25% in principal amount of all of the outstanding Securities of
that Series, by notice to the Company and to the Trustee, may declare the
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, and any accrued interest on, all the Securities of
that Series to be due and payable.  Upon such declaration, such Principal (or,
in the case of Original Issue Discount Securities, such specified amount) and
any accrued interest shall be due and payable immediately.  The Holders of a
majority in principal amount of all of the Securities of that Series, by notice
to the Trustee, may rescind such a declaration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing
Events of Default have been cured or waived except nonpayment of Principal or
interest that has become due solely because of the acceleration.  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 waiver or





                                      -34-
<PAGE>   36
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
former 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 proceedings had been taken.

SECTION 6.3.  Other Remedies Available to Trustee.

         (a)  If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy to collect payment of Principal or interest on the
Securities of the Series that is in default or to enforce the performance of
any provision of the Securities of that Series or this Indenture.

         (b)  The Trustee may maintain a proceeding even if it does not possess
any of the Securities or does not produce any of them in the proceeding.  A
delay or omission by the Trustee or any Securityholder in exercising any right
or remedy accruing upon an Event of Default shall not impair the right or
remedy or constitute a waiver of or acquiescence in the Event of Default.  No
remedy is exclusive of any other remedy.  All available remedies are
cumulative.

SECTION 6.4.  Waiver of Existing Defaults.

         The Holders of a majority in principal amount of any Series of
Securities by notice to the Trustee may waive an existing Default with respect
to that Series and its consequences except a Default in the payment of the
Principal of or interest on any Security.

SECTION 6.5.  Control by Majority.

         The Holders of a majority in principal amount of the Securities of
each Series affected (with each such Series voting as a class) may 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 it with respect to
the Securities of that Series.  However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture, if the Trustee in good
faith shall determine that the action or proceedings so directed may involve
the Trustee in personal liability or that is unduly prejudicial to the rights
of the Securityholders of that Series, it being understood that (subject to
Section 7.1) the Trustee shall have no duty to ascertain whether or not such
actions or forebearances are unduly prejudicial to such Securityholders.

SECTION 6.6.  Limitation on Suits by Securityholders.

         A Securityholder may pursue a remedy with respect to this Indenture or
the Securities of any Series only if:

                 (1)  the Holder gives to the Trustee written notice of a
         continuing Event of Default with respect to Securities of that Series;

                 (2)  the Holders of at least 25% in principal amount of the
         Securities of that Series make a written request to the Trustee to
         pursue the remedy;





                                      -35-
<PAGE>   37
                 (3)  such Holder or Holders offer to the Trustee indemnity
         satisfactory to the Trustee against any loss, liability or expense to
         be, or which may be, incurred by the Trustee in pursuing the remedy;

                 (4)  the Trustee does not comply with the request within 60
         days after receipt of the request and the offer of indemnity; and

                 (5)  during such 60-day period, the Holders of a majority in
         principal amount of the Securities of that Series do not give the
         Trustee a direction inconsistent with the request.

         A Securityholder of any Series may not use this Indenture to prejudice
the rights of another Securityholder of that Series or any other Series or to
obtain a preference or priority over another Securityholder of that Series or
any other Series.

SECTION 6.7.  Rights of Holders to Receive Payment.

         Notwithstanding any other provision of this Indenture, the right of
any Holder of a Security to receive payment of Principal and interest on the
Security, on or after the respective due dates expressed in the Security, and
the right of any Holder of a coupon to receive payment of interest due as
provided in such coupon, or to bring suit for the enforcement of any such
payment on or after such respective dates, shall not be impaired or affected
without the consent of such Holder.

SECTION 6.8.  Collection Suits by Trustee.

         If an Event of Default specified in Section 6.1 (1) or (2) occurs and
continues for the period, if any, specified therein, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Company
for the whole amount of such Principal and interest then remaining unpaid.

SECTION 6.9.  Trustee May File Proofs of Claim.

         The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee and the Securityholders allowed in any judicial proceedings relating to
the Company, its creditors or its property.

SECTION 6.10.  Priorities.

         If the Trustee collects any money pursuant to this Article, it shall
pay out the money in the following order:

                 FIRST:  to the Trustee for amounts due under Section 7.7;

                 SECOND:  to Holders of Securities in respect of which or for
         the benefit of which such money has been collected for amounts due and
         unpaid on such Securities for Principal and interest, ratably, without
         preference or priority of any kind, according to the amounts due and
         payable on such Securities for Principal and interest, respectively;
         and

                 THIRD:  to the Company.





                                      -36-
<PAGE>   38
         The Trustee may fix a record date (with respect to Registered
Securities) and payment date for any such payment to Holders of Securities.

SECTION 6.11.  Undertaking for Costs.

         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, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Company, a suit by the Trustee, a
suit by a Holder for the enforcement of the payment of the Principal of, or
interest on and any additional amounts on any Security, or a suit by a Holder
or Holders of more than 10% in Principal amount of the Securities of any
Series.

                                    TRUSTEE

SECTION 7.1.  Duties of Trustee.

         (a)  If an Event of Default has occurred and is continuing, the
Trustee shall exercise its rights and powers under this Indenture 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.

         (b)  Except during the continuance of an Event of Default:

                 (1)  The Trustee need perform only those duties that are
         specifically set forth in this Indenture and no implied covenants or
         obligations shall be read into this Indenture against the Trustee.

                 (2)  In the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements
         of this Indenture.  However, the Trustee shall examine the
         certificates and opinions to determine whether or not they conform to
         the requirements of this Indenture.

         (c)  The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

                 (1)  This paragraph does not limit the effect of paragraph (b)
         of this Section.

                 (2)  The Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Officer, unless it is proved that
         the Trustee was negligent in ascertaining the pertinent facts.

or power unless it receives indemnity satisfactory to it against any loss,
liability or expense.

SECTION 7.2.  Rights of Trustee.

         (a)  The Trustee may rely on any document believed by it to be genuine
and to have been signed or presented by the proper person.  The Trustee need

         (b)  Before the Trustee acts or refrains from acting, it may consult
with counsel or require an Officers' Certificate or an Opinion of Counsel.  The

certificate of an Officer or Officers delivered pursuant to Section 2.2(b), an
Officers' Certificate or an Opinion of Counsel.

         (c)  The Trustee may act through agents and shall not be responsible
for the misconduct or negligence of any agent appointed with due care.

report, notice, request, consent, order, approval, appraisal, bond, debenture,
note, coupon, security, or other paper or document unless requested in writing
to do so by the Holders of not less than a majority in aggregate principal
amount of the Securities then outstanding; provided, 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 expenses or liabilities as a condition to
proceeding; the reasonable expenses of every such examination shall be paid by
the Company or, if advanced by the Trustee, shall be repaid by the Company upon
demand.

         (f)  The Trustee shall not be required to give any bond or surety in
respect of the performance of its powers and duties hereunder.

covenants, conditions and agreements contained herein and shall be entitled in
connection herewith to examine the books, records and premises of the Company.

         (h)  The permissive rights of the Trustee to do things enumerated in
this Indenture shall not be construed as a duty and the Trustee shall not be
answerable for other than its negligence or willful misconduct.

         (i)  Except for (i) a default under Section 7.1(1) or (2) hereof, or
(ii) any other event of which the Trustee has "actual knowledge" and which
event, with the giving of notice or the passage of time or both, would
constitute an Event of Default under this Indenture, the Trustee shall not be
deemed to have notice of any default or Event of Default unless specifically
notified in writing of such event by the Company or the Holders of not less
than 25% in aggregate principal amount of the Securities then outstanding; as
used herein, the term "actual knowledge" means the actual fact or statement of
knowing, without any duty to make any investigation with regard thereto.

SECTION 7.3.  Individual Rights of Trustee.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or an
Affiliate with the same rights it would have if it were not Trustee.  Any Agent
may do the same with like rights.  However, the Trustee is subject to Sections
7.10 and 7.11.

SECTION 7.4.  Trustee's Disclaimer.

         The Trustee makes no representation as to the validity or adequacy of
this Indenture or the Securities.  It shall not be accountable for the
Company's use of the proceeds from the Securities or for monies paid over to
the Company pursuant to the Indenture, and it shall not be responsible for any
statement in the Securities other than its certificate of authentication.

SECTION 7.5.  Notice of Defaults.

         If a Default occurs and is continuing with respect to the Securities
of any Series and if it is known to the Trustee, the Trustee shall mail to each
Holder of a Security of that Series entitled to receive reports pursuant to
Section 4.2(c) (and, if Unregistered Securities of that Series are outstanding,
shall cause to be published at least once in an Authorized Newspaper in each of
The City of New York, London and, if Securities of that Series are listed on
The Luxembourg Stock Exchange, Luxembourg) notice of the Default within 90 days
after it occurs.  Except in the case of a Default in payment of Principal,
interest or additional amounts on the Securities of any Series, or in the
payment of any sinking fund installment, the Trustee may withhold the notice if
and so long as a committee of its Responsible Officers in good faith determines
that withholding such notice is in the interests of Securityholders of that
Series.

         (a)  On or before the first anniversary date of the first issue of a
Series of Securities and thereafter at intervals of not more than 12 months,
the Trustee shall, if required by Section 313(a) of the TIA, mail to each
Securityholder of that Series entitled to receive reports pursuant to Section
4.2(c) a brief report dated as of such date that complies with TIA Section
313(a).  The Trustee also shall comply with TIA Section 313(b).

         (b)  The Trustee shall transmit to Securityholders of each Series, as
hereinafter provided, and to the Company a brief report with respect to the
character and amount of any advances (and if the Trustee elects so to state,
the circumstances surrounding the making thereof) made by the Trustee (as such)
since the date of the last report transmitted pursuant to the provisions of
subsection (a) of this Section 7.6 (or if no such report has yet been so
transmitted, since the date of execution of this Indenture), for the
reimbursement of which it claims or may claim a lien or charge prior to that of
the Securities of such Series on property or funds held or collected by it as
Trustee, and which it has not previously reported pursuant to this subsection,
except that the Trustee shall not be required (but may elect) to report such
advances if such advances remaining unpaid at any time aggregate ten percent or
less of the principal amount at Stated Maturity of Securities of such Series
outstanding at such time, such report to be transmitted within 90 days after
such time.

         (c)  Reports to Securityholders pursuant to this Section 7.6 shall be
transmitted by mail:

                 (1)  to all Holders of Registered Securities of each Series,
         as the names and addresses of such Holders appear upon the register
         for each Series of Securities;

                 (2)  to such Holders of Unregistered Securities as have,
         within two years preceding such transmission, filed their names and
         addresses with the Trustee for that purpose; and

                 (3)  except in the case of reports pursuant to subsection (b)
         of this Section 7.6, to each Holder whose name and address is
         preserved at the time by the Trustee, as provided in Section 2.7(a).

                 (4)  At the time that it mails such a report to
         Securityholders of any Series, the Trustee shall file a copy of that
         report with the SEC and with each stock exchange on which the
         Securities of that Series are listed.  The Company shall provide
         written notice to the Trustee when the Securities of any Series are
         listed on any stock exchange.

SECTION 7.7.  Compensation and Indemnity.

         (a)  The Company shall pay to the Trustee from time to time, and the
Trustee shall be entitled to, reasonable compensation for its services.  The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust.  The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred by it in connection
with the performance of its duties under this Indenture.  Such expenses shall
include the reasonable compensation and expenses of the Trustee's agents and
counsel.

         (b)  The Company shall indemnify the Trustee against any loss,
liability or expense incurred by it arising out of or in connection with its
acceptance or administration of the trust or trusts





                                      -40-

hereunder.  The Trustee shall notify the Company promptly of any claim for
which it may seek indemnity.

         (c)  The Company need not reimburse any expense or indemnify against
any loss or liability incurred by the Trustee through negligence or willful
misconduct.

         (d)  To secure the payment obligations of the Company pursuant to this
Section, the Trustee shall have a lien prior to the Securities of any Series on
all money or property held or collected by the Trustee, except that held in
trust to pay Principal and interest on particular Securities of a Series.

         (e)  If the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.1(5) or (6) occurs, such expenses and the
compensation for such services are intended to constitute expenses of
administration under any Bankruptcy Law.

SECTION 7.8.  Replacement of Trustee.

         (a)  The resignation or removal of the Trustee and the appointment of
a successor Trustee shall become effective only upon the successor Trustee's
acceptance of appointment as provided in this Section.

         (b)  The Trustee may resign with respect to the Securities of any
Series by so notifying the Company.  The Holders of a majority in principal
amount of the Securities of any Series may remove the Trustee with respect to
that Series by so notifying the Trustee and the Company and may appoint a
successor Trustee for such Series with the Company's consent.  The Company may
remove the Trustee with respect to Securities of any Series if:

                 (1)  the Trustee fails to comply with Section 7.10;

                 (2)  the Trustee is adjudged a bankrupt or an insolvent;

                 (3)  a receiver or public officer takes charge of the Trustee
         or its property; or

                 (4)  the Trustee becomes incapable of acting.

         (c)  If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, with respect to Securities of any Series,
the Company shall promptly appoint a successor Trustee for such Series.

         (d)  If a successor Trustee with respect to the Securities of any
Series does not take office within 30 days after the retiring Trustee resigns
or is removed, the retiring Trustee, the Company or the Holders of at least 10%
in principal amount of the Securities of the applicable Series may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such Series.

         (e)  If the Trustee with respect to the Securities of any Series fails
to comply with Section 7.10, any Securityholder of the applicable Series may
petition any court of competent jurisdiction for the removal of such Trustee
and the appointment of a successor Trustee.

Section 7.8 (h), the resignation or removal of the retiring Trustee for any
Series of Securities shall become effective, and the successor Trustee shall
have all the rights, powers and duties of the retiring Trustee with respect to
all Series of Securities for which the successor Trustee is to be acting as
Trustee under this Indenture.  The retiring Trustee shall promptly transfer all
property held by it as Trustee with respect to such Series of Securities to the
successor Trustee subject to the lien provided for in Section 7.7. The Company
shall give notice of each appointment of a successor Trustee for any Series of
Securities by mailing written notice of such event by first-class mail to the
Holders of Registered Securities of such Series entitled to receive reports
pursuant to Section 4.2(c) and, if any Unregistered Securities are outstanding,
by publishing notice of such event once in an Authorized Newspaper in each of
The City of New York, London, and, if Securities of that Series are listed on
The Luxembourg Stock Exchange, Luxembourg.

         (g)  All provisions of this Section 7.8 except subparagraphs (b) (1),
(e) and (h) and the words "subject to the lien provided for in Section 7.7" in
subparagraph (f) shall apply also to any Paying Agent located outside the U.S.
and its possessions and required by Section 2.4.

         (h)  In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more Series, the Company, the retiring
Trustee and such successor Trustee shall execute and deliver a supplemental
indenture wherein such successor Trustee shall accept such appointment and
which (1) shall contain such provisions as shall be necessary or desirable to
transfer and confirm to, and to vest in, such successor Trustee all the rights,
powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those Series to which the appointment of such successor
Trustee relates, (2) if the retiring Trustee is not retiring with respect to
all Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those Series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) 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 trusts 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
administered by any other such Trustee.

         (i)  No successor Trustee shall accept appointment as provided in this
Section 7.8 unless at the time of such acceptance such successor Trustee shall
be qualified and eligible under the provisions of Section 7.10.

SECTION 7.9.  Successor Trustee, Agents by Merger, etc.

         If the Trustee or any Agent consolidates with, merges or converts

assets to, another corporation, the successor corporation, without any further
act, shall be the successor Trustee or Agent, as the case may be.

SECTION 7.10.  Eligibility; Disqualification.

         This Indenture shall always have a Trustee with respect to each Series
of Securities who satisfies the requirements of TIA Section 310 (a) (1).  The

$10,000,000 as set forth in its most recent published annual report of

of the Company now or hereafter existing which may be excluded under the
proviso of TIA Section  310(b) (1).

who has resigned or been removed shall be subject to TIA Section  311 (a) to
the extent indicated.

         terms and conditions of Securities of any Series as provided in
         Section 2.2, to establish the form of any certifications required to
         be furnished pursuant to the term of this Indenture or any Series of
         Securities, to add to the rights of the Holders of any Series of
         Securities, or to surrender any right or power conferred on the
         Company;

                 (7)  to add to the rights of the Holders of any series of
                      Securities; or

                 (8)  to provide for the appointment of a successor Trustee.

                 (9)  The Trustee shall sign any supplemental indenture
authorized pursuant to this Section 9.1 if the supplemental indenture does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it.  In signing such supplemental
indenture the Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Officers' Certificate and an Opinion of Counsel
stating that such supplemental indenture is authorized or permitted by this
Indenture.

SECTION 9.2.  With Consent of Holders.

         (a)  With the written consent of the Holders of a majority in
principal amount of the outstanding Securities of each Series affected by such
supplemental indenture (with each Series voting as a class), the Company and
the Trustee may enter into a supplemental indenture to add any provisions to or
to change or eliminate any provisions of this Indenture or of any supplemental
indenture or to modify, in each case in any manner not covered by Section 9.1,
the rights of the Securityholders of each such Series.  The Holders of a
majority in principal amount of the outstanding Securities of each Series
affected by such waiver (with each Series voting as a class), by notice to the
Trustee, may waive compliance by the Company with any provision of this
Indenture, any supplemental indenture or the Securities of any such Series
except a Default in the payment of the Principal of or interest on any
Security.  However, without the consent of each Securityholder affected, an
amendment or waiver may not:

                 (1)  reduce the amount of Securities whose Holders must
                      consent to an amendment or waiver;

                 (2)  change the rate of or change the time for payment of
                      interest on any Security;

                 (3)  change the Principal of or change the Stated Maturity of
                      any Security;

                 (4)  reduce any premium payable upon the redemption of any
                      Security;

                 (5)  waive a Default in the payment of the Principal of or
                      interest on any Security;

                 (6)  make any Security payable in money other than that stated
                      in the Security; or

                 (7)  make any change in Section 6.4, 6.7 or 9.2(a) (third
                      sentence).





                                      -47-
<PAGE>   49
         (b)  It is not necessary under this Section 9.2 for the
Securityholders to consent to the particular form of any proposed supplemental
indenture, but it is sufficient if they consent to the substance thereof.

         (c)  Upon the request of the Company, accompanied by a copy of a
resolution of the Board of Directors certified by the Secretary or an Assistant
Secretary of the Company 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.

         (d)  Promptly after the execution by the Company and the Trustee of
any supplemental indenture pursuant to the provisions of this Section 9.2, the
Company shall transmit by mail a notice, setting forth in general terms the
substance of such supplemental indenture, to all Holders of Registered
Securities, as the names and addresses of such Holders appear on the register
for each Series of Securities, and to such Holders of Unregistered Securities
as are entitled to receive reports pursuant to Section 4.2(c).  Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such supplemental indenture.

         (e)  Upon the execution of any supplemental indenture pursuant to the
provisions of this Article Nine, this Indenture shall be and be deemed to be
modified and amended in accordance therewith and the respective rights,
limitation of rights, obligations, duties and immunities under this Indenture
of the Trustee, the Company and the Securityholders 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 9.3.  Compliance with Trust Indenture Act.

         Every amendment to this Indenture or the Securities of one or more
Series shall be set forth in a supplemental indenture that complies with the
TIA as then in effect.

SECTION 9.4.  Revocation and Effect of Consents.

         Until an amendment or waiver becomes effective, a consent to it by a
Holder of a Security is a continuing consent by the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security, even if notation of the consent is not made
on any Security.  However, any such Holder or subsequent Holder may revoke the
consent as to his Security or portion of a Security if the Trustee receives the
notice of revocation before the date the amendment or waiver becomes effective.
After an amendment or waiver becomes effective, it shall bind every
Securityholder of each Series affected by such amendment or waiver.

SECTION 9.5.  Notation on or Exchange of Securities.

         The Trustee may place an appropriate notation about an amendment or
waiver on any Security of any Series thereafter authenticated.  The Company in
exchange for Securities of that Series may





                                      -48-

issue and the Trustee shall authenticate new Securities of that Series that
reflect the amendment or waiver.

                          FIRST SUPPLEMENTAL INDENTURE



         THIS FIRST SUPPLEMENTAL INDENTURE, dated as of January 22, 1997, is
between UNION TANK CAR COMPANY, a Delaware corporation (the "Company"), and
HARRIS TRUST AND SAVINGS BANK, as trustee (herein called the "Trustee").


                             PRELIMINARY STATEMENT

         The Company and the Trustee have entered into an Indenture (herein
called the "Indenture"), dated as of January 16, 1997.  Capitalized terms used
herein, not otherwise defined herein, shall have the meanings given them in the
Indenture.

         Section 9.1 of the Indenture provides that, under certain
circumstances, a supplemental indenture may be entered into by the Company and
the Trustee without the consent of any Holders of the Securities.  In
accordance with the terms of Section 9.1(6) of the Indenture, the Company has
authorized this First Supplemental Indenture which is in the form required by
the terms of the Indenture.  This First Supplemental Indenture modifies the
terms and the Indenture insofar as they are applicable to the Securities
referred to herein issued under the Indenture after the date of this First
Supplemental Indenture.

         The parties agree that all things necessary to make this First
Supplemental Indenture a valid agreement of the Company and the Trustee and a
valid amendment of and supplement to the Indenture have been done.

         NOW, THEREFORE, THIS FIRST SUPPLEMENTAL INDENTURE WITNESSETH:

         For and in consideration of the premises, it is mutually covenanted
and agreed, for the equal and proportionate benefit of all Holders of the
Securities referred to herein issued under the Indenture from and after the
date of this First Supplemental Indenture, as follows:

         1.  Pursuant to Section 2.2, the form, terms and conditions of the
Securities to be issued pursuant to this First Supplemental Indenture shall be

                 (b)  The Securities shall be limited in the aggregate
         principal amount of $150,000,000 (except for Securities authenticated
         and delivered upon registration of transfer of, or in exchange for, or
         in lieu of, other Securities pursuant to Section 2.8, 2.9 or 2.12 of
         the Indenture).
<PAGE>   2
                 (c)  The principal amount of the Securities shall mature on
         February 1, 2007, subject to any declaration of acceleration of the
         maturity pursuant to Section 6.2 of the Indenture or provable in
         bankruptcy pursuant to Section 6.3 of the Indenture.

                 (d)  The Securities shall bear interest from January 22, 1997
         at the rate of     7 1/8% per annum, payable on each February 1 and
         August 1, commencing on August 1, 1997, to the holders of record of
         the Securities on January 15 or July 15, as the case may be, next
         preceding such February 1 or August 1.  Interest on the Securities
         will be computed on the basis of a 360-day year of twelve 30-day
         months.

                 (e)  The Securities shall not be redeemable prior to maturity
         and the Company shall have no obligation to redeem or purchase the
         Securities pursuant to any sinking fund or analogous provision.

                 (f)  The minimum denominations for the Securities shall be
         $1,000 and integral multiples of $1,000 in excess thereof.

                 (g)      The Securities shall be subject to defeasance in
         accordance with the terms of Article VIII of the Indenture.

                 (h)  The Securities shall be issued in the form of fully
         registered Global Securities, which will be deposited with, or on
         behalf of, the Depository Trust Company, New York, New York (the
         "Depository") and registered in the name of the Depository's nominee
         and the circumstances under which any Global Security may be
         transferred to, and registered and exchanged for Securities registered
         in the name of a Person other than the Depository shall be as set
         forth in Section 2.8 of the Indenture.  Principal of, premium, if any,
         and interest payments on the Securities will be made to the Depository
         or its nominee; provided, however, that at the option of the Company
         payment of interest may be made by check mailed to the address of the
         Person entitled thereto as such address shall appear in the Security
         Register.

                 The Company shall execute and the Trustee shall, in accordance
         with Sections 2.3 and 2.15 of the Indenture, authenticate and deliver,
         such Global Security or Securities substantially in the form of
         Exhibit A attached hereto.

                 Members of, or participants in, the Depository shall have no
         rights under the Indenture with respect to any Global Security held on
         their behalf by the Depository or its nominee.  The Depository or its
         nominee may be treated by the Company, the Trustee and any agent of
         the Company or the Trustee as the absolute owner of such Global
         Security for all purposes whatsoever.  Notwithstanding the foregoing,
         nothing herein shall prevent the Company, the Trustee, or any agent of
         the Company or the Trustee from giving effect to any written
         certification, proxy or other authorization furnished by the
         Depository or impair, as between the Depository and its agent

         members, the operation of customary practices governing the exercise
         of the rights of a holder of any Security.

                 If at any time the Depository for a Global Security notifies
         the Company that it is unwilling or unable to continue as Depository

         Securities for such series shall no longer be eligible or in good

         other applicable statute or regulation, the Company shall appoint a

         aggregate principal amount equal to the principal amount of the Global

any respect with regard to Securities issued thereunder prior to the date of
this First Supplemental Indenture.

         UNION TANK CAR COMPANY, a corporation duly organized and existing
under the laws of the State of Delaware (the "Company", which term includes any
successor corporation under the Indenture hereinafter referred to), for value
received, hereby promises to pay to Cede & Co., or registered assignees, the
principal sum of One Hundred Fifty Million Dollars ($150,000,000) on February
1, 2007, and to pay interest thereon from January 22, 1997, or from the most
recent Interest Payment Date to which interest has been paid or duly provided
for, semi-annually on February 1 and August 1 of each year, commencing August
1, 1997, at the rate of 7 1/8% per annum, until the principal hereof becomes
due and payable, and at such rate on any overdue principal and (to the extent
that the payment of such interest shall be legally enforceable) on any overdue
installment of interest.  The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture,
be paid to the Person in whose name this Debt Security (or one or more
Predecessor Securities) is registered at the close of business of the Regular
Record Date for such interest payment, which shall be the January 15 or July 15
(whether or not a Business Day), as the case may be, next preceding such
Interest Payment Date.  Any such interest not so punctually paid or duly
provided for shall forthwith cease to be payable to the registered Holder on
such Regular Record Date by virtue of his having been such Holder, and may
either be paid to the Person in whose name this Debt Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Debt Securities of this
series not less than 10 days prior to such Special Record Date, or be paid at
any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Debt Securities of this series may be
listed, and upon such notice as may be required by such exchange, all as more
fully provided in said Indenture.

         Payment of the principal of (and premium, if any) and interest on this
Debt Security will be made at the office or agency of the Company maintained
for that purpose in the Borough of Manhattan, the City of Chicago and State of
Illinois, in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company payment of interest may be
made by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register.
<PAGE>   7
         This Note shall not be valid until authenticated by the manual
signature of the Trustee or an authenticating agent.

         This security is one of a duly authorized issue of securities of the
Company (the "Debt Securities"), issued or to be issued in one or more series
under an indenture (the "Indenture"), dated as of January 16, 1997, as
supplemented by the first supplemental indenture thereto, dated as of January
22, 1997, each between the Company and Harris Trust and Savings Bank, as
trustee (the "Trustee", which term includes any successor Trustee under the
Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Trustee and the
Holders of the Debt Securities and of the terms upon which the Debt Securities
are, and are to be, authenticated and delivered.  This Debt Security is one of
the series designated on the face hereof limited in aggregate principal amount
to $150,000,000.

         The Debt Securities of this series are not subject to redemption prior
to maturity.

         If an Event of Default with respect to the Debt Securities of this
series shall have occurred and be continuing, the principal of all the Debt
Securities of this series may be declared due and payable in the manner and
with the effect provided in the Indenture.

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Debt Securities to be affected
under the Indenture at any time by the Company and the Trustee with the consent
of the Holders of not less than a majority in aggregate principal amount of the
outstanding Debt Securities to be affected.  The Indenture also contains
provisions permitting the Holders of specified percentages in aggregate
principal amount of the Debt securities of any series at the time outstanding,
on behalf of the Holders of all the Debt Securities of such series, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences.  Any such consent or
waiver by the Holder of this Debt Security shall be conclusive and binding upon
such Holder and upon all future Holders of this Debt Security and of any Debt
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Debt Security.

         Holders of Debt Securities may not enforce their rights pursuant to
the Indenture or the Debt Securities except as provided in the Indenture.  No
reference herein to the Indenture and no provision of this Debt Security or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Debt Security at the times, place and rate, and in the coin or
currency, herein prescribed.

         The Debt Securities of this series are issuable in registered form
without coupons in denominations of $1,000 and any integral multiple thereof.
As provided in the Indenture and subject to certain limitations therein set
forth, Debt Securities of this series are exchangeable for a like aggregate
principal amount of Debt Securities of this series of different authorized
denominations, as requested by the Holder surrendering the same.

         As provided in the Indenture and subject to certain limitations set
forth, the transfer of this Debt Security is registerable in the Security
Register of the Company, upon surrender of this Debt





                                      -2-

Security for registration of transfer at the office or agency of the Company in
the City of Chicago and State of Illinois, duly endorsed by, or accompanied by
a written instrument of transfer in form satisfactory to the Company, the
Security Registrar and the Trustee duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Debt
Securities of this series, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

         This Debt Security is in the form of a Global Security as provided in
the Indenture.  If at any time the Depository notifies the Company that it is
unwilling or unable to continue as Depository for this Debt Security or if at
any time the Depository for this series shall no longer be eligible or in good
standing under the Securities Exchange Act of 1934, as amended, or other
applicable statute or regulation, the Company shall appoint a successor
Depository with respect to this Debt Security.  If a successor Depository for
this Debt Security is not appointed by the Company within 90 days after the
Company receives notice or becomes aware of such ineligibility or an Event of
Default has occurred and is continuing, the Company will execute, and the
Trustee or its agent, upon receipt of a Company Request for the authentication
and delivery of certificates representing Debt Securities of this series in
exchange for this Debt Security, will authenticate and deliver, certificates
representing Debt Securities of this series of like tenor and terms in an
aggregate principal amount equal to the principal amount of this Debt Security
in exchange for this Debt Security.

         The Company may at any time and in its sole discretion determine that
this Debt Security or portion hereof shall no longer be represented in the form
of a Global Security.  In such event the Company will execute, and the Trustee,
upon receipt of a Company Request for the authentication and delivery of
certificates representing Debt Securities of this series in exchange in whole
or in part for this Debt Security, will authenticate and deliver certificates
representing Debt Securities of this series of like tenor and terms in
definitive form in an aggregate principal amount equal to the principal amount
of this Debt Security or portion hereof in exchange for this Debt Security.

         If specified by the Company pursuant to the Indenture with respect to
this Debt Security, the Depository may surrender this Debt Security in exchange
in whole or in part for certificates representing Debt Securities of this
series of like tenor and terms in definitive form on such terms as are
acceptable to the Company and the Depository.  Thereupon the Company shall
execute, and the Trustee or its agent shall authenticate and deliver, without a
service charge, (1) to each Holder specified by the Security Registrar or the
Depository a certificate or certificates representing Debt Securities of this
series of like tenor and terms and of any authorized denomination as requested
by such person in an aggregate principal amount equal to and in exchange for
such Holder's beneficial interest as specified by the Security Registrar or the
Depository in this Debt Security; and (2) to the Depository a new Global
Security of like tenor and terms and in an authorized denomination equal to the
difference, if any, between the principal amount of the surrendered Debt
Security and the aggregate principal amount of certificates representing Debt
Securities delivered to Holders thereof.

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

         Prior to due presentation of this Debt Security for registration or
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Debt





                                      -3-

Security is registered as the owner hereof for all purposes, whether or not
this Debt Security be overdue, and neither the Company, the Trustee nor any
such agent shall be affected by notice to the contrary.

         No recourse shall be had for the payment of the principal or of
interest in this Debt Security, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture or any indenture
supplemental hereto, against any incorporator, stockholder, officer or
director, as such, past, present or future, of the Company or of any 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
liabilities being, by the acceptance hereof and as part of the consideration
for the issue hereof, expressly waived and released.

         The Debt Securities of this series are subject to defeasance at the
option of the Company as provided in the Indenture.

         This Note shall be governed by and construed in accordance with the
internal laws of the State of Illinois, without regard to its conflict of laws
provisions.

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