ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Georgia Business Corporation Code (the "GBCC") permits, under certain
circumstances, the indemnification of officers, directors, employees and agents
of a corporation with respect to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative, to
which such person was or is a party or is threatened to be made a party by
reason of his or her action in such capacity for, or at the request of, such
corporation. To the extent that such person is successful in defending any such
suit, Georgia law provides that he or she shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him or her in
connection therewith.
 
     The Company's Bylaws provide for the indemnification of the Company's
directors, officers, employees and agents in accordance with the GBCC. Georgia
law also provides that, with certain exceptions, the above rights will not be
deemed exclusive of other rights of indemnification contained in any Bylaw,
resolution or agreement approved by the holders of a majority of the stock. The
Company's Bylaws provide that the Company may purchase and maintain insurance on
behalf of directors, officers, employees and agents, as well as others serving
at their request, against any liabilities asserted against such persons whether
or not the Company would have the power to indemnify such persons against such
liability under the GBCC. The Company has purchased and maintains such
insurance.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been advised
that in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Securities Act and
is therefore unenforceable.

ITEM 17.  UNDERTAKINGS.
 
     (a) The undersigned Registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in this Registration Statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high and of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20 percent change in
        the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement;
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in this registration statement
        or any material change to such information in the registration
        statement;
 
provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the registration statement.
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in this Registration
Statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
 
     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     (d) The undersigned registrant hereby undertakes that:
 
          (1) For the purpose of determining any liability under the Securities
     Act of 1933, the information omitted from the form of prospectus filed as
     part of this Registration Statement in reliance upon
                                      II-3
<PAGE>   5
 
     Rule 430A and contained in a form of prospectus filed by the Registrant
     pursuant to Rule 424(b)(1) or (4), or 497(h) under the Securities Act shall
     be deemed to be part of this Registration Statement as of the time it was
     declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 
     (j) The undersigned Registrant hereby undertakes to file an application for
the purpose of determining the eligibility of the trustee to act under
subsection (a) of Section 310 of the Trust Indenture Act in accordance with the
rules and regulations prescribed by the Commission under Section 305(b)(2) of
the Act.

such calculation or in relying upon any such request, demand, authorization,
direction, notice, consent or waiver, only Securities which a Responsible
Officer of the Trustee actually knows to be so owned shall be so disregarded.
Securities so owned which have been pledged in good faith may be regarded as

is not the Company or any other obligor upon the Securities or any Affiliate of
the Company or of such other obligor.

         Upon any application or request by the Company to the Trustee to take
any action under any provision of this Indenture, the Company shall furnish to
the Trustee an Officers' Certificate stating that all conditions precedent, if
any, provided for in this Indenture (including covenants, compliance with which
constitute conditions precedent) relating to the proposed action have been

         SECTION 103.     Form of Documents Delivered to Trustee.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion as to some matters and one or more
other such Persons as to other matters, and any such Person may certify or give
an opinion as to such matters in one or several documents.

         Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon an Opinion of Counsel, or a
certificate or representations by counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the opinion, certificate or
representations with respect to the matters upon which his certificate or
opinion is based are erroneous.  Any such Opinion of Counsel or certificate or
representations may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the
Company stating that the information as to such factual matters is in the
possession of the Company, unless such counsel knows that the certificate or
opinion or representations as to such matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         SECTION 104.     Acts of Holders.

         (a)     Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders of the Outstanding Securities of all series or one or more series, as
the case may be, may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents duly
appointed in writing.  If Securities of a series are issuable as Bearer
Securities, any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders of Securities of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof, whether in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of Article Fifteen, or a combination of such
instruments and any such record.  Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or record
or both are delivered to the Trustee and, where it is hereby expressly required,
to the Company.  Such instrument or instruments and any such record (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments or so voting
at any such meeting.  Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for any purpose of this Indenture and (subject to Section 612)
conclusive in favor of the Trustee and the Company and any agent of the Trustee
or the Company, if made in the manner provided in this Section.  The record of
any meeting of Holders of Securities shall be proved in the manner provided in
Section 1506.

         (b)     The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a


                                      11
<PAGE>   19

witness of such execution or by a certificate of a notary public or other
officer authorized by law to take acknowledgments of deeds, certifying that
the individual signing such instrument or writing acknowledged to him the
execution thereof.  Where such execution is by a signer acting in a capacity
other than his individual capacity, such certificate or affidavit shall also
constitute sufficient proof of his authority.  The fact and date of the
execution of any such instrument or writing, or the authority of the Person
executing the same, may also be proved in any other reasonable manner which the
Trustee deems sufficient.

         (c)     The ownership of Registered Securities shall be proved by the
Security Register or by a certificate of the Security Registrar.

         (d)     The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed, as
depository, by any trust company, bank, banker or other depository, wherever
situated, if such certificate shall be deemed by the Trustee to be
satisfactory, showing that at the date therein mentioned such person had on
deposit with such depository, or exhibited to it, the Bearer Securities therein
described; or such facts may be proved by the certificate or affidavit of the
Person holding such Bearer Securities, if such certificate or affidavit is
deemed by the Trustee to be satisfactory.  The Trustee and the Company may
assume that such ownership of any Bearer Security continues until (1) another
certificate or affidavit bearing a later date issued in respect of the same
Bearer Security is produced, or (2) such Bearer Security is produced to the
Trustee by some other Person, or (3) such Bearer Security is surrendered in
exchange for a Registered Security, or (4) such Bearer Security is no longer
Outstanding.  The ownership of Bearer Securities may also be proved in any
other manner which the Trustee deems sufficient.

         (e)     If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, in or pursuant to a Board
Resolution, fix in advance a record date for the determination of Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do
so.  Notwithstanding TIA Section 316(c), such record date shall be the record
date specified in or pursuant to such Board Resolution, which shall be a date
not earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation
is completed.  If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close
of business on such record date shall be deemed to be Holders for the purposes
of determining whether Holders of the requisite proportion of Outstanding
Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that
purpose the Outstanding Securities shall be computed as of such record date;
provided that no such authorization, agreement or consent by the Holders on
such record date shall be deemed effective unless it shall become effective
pursuant to the provisions of this Indenture not later than eleven months after
the record date.

         (f)     Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee, any
Security Registrar, any Paying Agent, any Authenticating Agent or the


                                      12
<PAGE>   20

Company in reliance thereon, whether or not notation of such action is made
upon such Security.

         SECTION 105.     Notices, etc., the Trustee and Company.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to or filed with,

         (1)     the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee at its Corporate Trust Office, Attention:
Corporate Trust Department, or

         (2)     the Company by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing and mailed, first class postage prepaid, to the Company
addressed to it at the address of its principal office specified in the first
paragraph of this Indenture or at any other address previously furnished in
writing to the Trustee by the Company.

         SECTION 106.     Notice to Holders; Waiver.

         Where this Indenture provides for notice of any event to Holders of
Registered Securities by the Company or the Trustee, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, to each such Holder affected by such
event, at his address as it appears in the Security Register, not later than
the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice.  In any case where notice to Holders of Registered
Securities is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein.  Any notice mailed to a Holder in the manner herein
prescribed shall be conclusively deemed to have been received by such Holder,
whether or not such Holder actually receives such notice.

         If by reason of the suspension of or irregularities in regular mail
service or by reason of any other cause it shall be impracticable to give such
notice by mail, then such notification to Holders of Registered Securities as
shall be made with the approval of the Trustee shall constitute a sufficient
notification to such Holders for every purpose hereunder.

         Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice
shall be sufficiently given if published in an Authorized Newspaper in The City
of New York and in such other city or cities as may be specified in such
Securities, and if the Securities of such series are listed on any stock
exchange outside the United States, in any place at which such Securities are
listed on a securities exchange to the extent that such securities exchange so
requires, on a Business Day, such publication to be not later than the latest
date, and not earlier than the earliest date, prescribed for the giving of such
notice.  Any such notice shall be deemed to have been given on the date of such
publication or, if published more than once, on the date of the first such
publication.



                                      13
<PAGE>   21



         If by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder.  Neither the failure to give notice by
publication to any particular Holder of Bearer Securities as provided above,
nor any defect in any notice so published, shall affect the sufficiency of such
notice with respect to other Holders of Bearer Securities or the sufficiency of
any notice to Holders of Registered Securities given as provided herein.

         Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of
the country of publication.

         Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice.  Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken
in reliance upon such waiver.

         SECTION 107.     Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

         SECTION 108.     Successors and Assigns.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

         SECTION 109.     Separability Clause.

         In case any provision in this Indenture or in any Security or coupon
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

         SECTION 110.     Benefits of Indenture.

         Nothing in this Indenture or in the Securities or coupons appertaining
thereto, express or implied, shall give to any Person, other than the parties
hereto, any Security Registrar, any Paying Agent, any Authenticating Agent and
their successors hereunder and the Holders any benefit or any legal or
equitable right, remedy or claim under this Indenture.

         SECTION 111.     No Personal Liability.

         No recourse under or upon any obligation, covenant or agreement
contained in this Indenture, in any Security or coupon appertaining thereto, or
because of any indebtedness evidenced thereby, shall be had against any
promoter, as such, or against any past, present or future shareholder, officer
or director, as such, of the Company or of any successor, either directly or
through the Company or any successor, under any rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any
legal or equitable proceeding or otherwise, all such liability being expressly
waived and released by the acceptance of


                                      14
<PAGE>   22

the Securities by the Holders thereof and as part of the consideration for the
issue of the Securities.

         SECTION 112.     Governing Law.

         This Indenture and the Securities and coupons shall be governed by and
construed in accordance with the laws of the State of Georgia.  This Indenture
is subject to the provisions of the TIA that are required to be part of this
Indenture and shall, to the extent applicable, be governed by such provisions.

         SECTION 113.     Legal Holidays.

         In any case where any Interest Payment Date, Redemption Date, Repayment
Date, sinking fund payment date, Stated Maturity or Maturity of any Security or
the last date on which a Holder has the right to convert or exchange a Security
at a particular conversion or exchange price shall not be a Business Day at any
Place of Payment, then (notwithstanding any other provision of this Indenture or
any Security or coupon other than a provision in the Securities of any series
which specifically states that such provision shall apply in lieu hereof),
payment of interest or any Additional Amounts or principal (and premium or
Make-Whole Amount, if any) need not be made at such Place of Payment on such
date, conversion or exchange need not be made at such Place of Payment on such
date, but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment Date,
Redemption Date, Repayment Date or sinking fund payment date, or at the Stated
Maturity or Maturity or on such last day for conversion or exchange, provided
that no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date, Redemption Date, Repayment Date, sinking fund
payment date, Stated Maturity or Maturity or on such last day for conversion or
exchange, as the case may be.

         SECTION 201.     Forms of Securities.

Securities, if any, and related coupons of each series, shall be in
substantially the forms as shall be established in or pursuant to one or more
indentures supplemental hereto or Board Resolutions, shall have such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture or any indenture supplemental hereto,
and may have such letters, numbers or other marks of identification or
designation and such legends or endorsements placed thereon as the Company may
deem appropriate and as are not inconsistent with the provisions of this
Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Securities may be listed, or to conform to usage.

         Unless otherwise specified as contemplated by Section 301, Bearer
Securities shall have interest coupons attached.

         The definitive Securities and coupons shall be printed, lithographed
or engraved or produced by any combination of these methods on a steel engraved
border or steel engraved borders or may be produced in any other manner, all as

         SECTION 202.     Form of Trustee's Certificate of Authentication.

         Subject to Section 611, the Trustee's certificate of


                                      15
<PAGE>   23

authentication shall be in substantially the following form:

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


                                             SunTrust Bank, Atlanta, as Trustee

                                                        Authorized Officer

         SECTION 203.     Securities Issuable in Global Form.
 
   
         If Securities of or within a series are issuable in global form, as
specified as contemplated by Section 301, then, notwithstanding clause (8) of
Section 301 and the provisions of Section 302, any such Security shall represent
such of the Outstanding Securities of such series as shall be specified therein
and may provide that it shall represent the aggregate amount of Outstanding
Securities of such series from time to time endorsed thereon and that the
aggregate amount of Outstanding Securities of such series represented thereby
may from time to time be increased or decreased to reflect exchanges,
maturities or redemptions. Any endorsement of a Security in global form to
reflect the amount, or any increase or decrease in the amount, of Outstanding
Securities represented thereby shall be made by the Trustee in such manner and
upon written instruction given by such Person or Persons as shall be specified
therein or in the Company Order to be delivered to the Trustee pursuant to
Section 303 or 304.  Subject to the provisions of Section 303 and, if
applicable, Section 304, the Trustee shall deliver and redeliver any Security in
permanent global form in the manner and upon written instructions given by the
Person or Persons specified therein or in the applicable Company Order. If a
Company Order pursuant to Section 303 or 304 has been, or simultaneously is,
delivered, any instructions by the Company with respect to endorsement or
delivery or redelivery of a Security in global form shall be in writing but need
not comply with Section 102.
    

         The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.


         Notwithstanding the provisions of Section 307, unless otherwise
specified as contemplated by Section 301, payment of principal of and any 
premium or Make-Whole Amount and interest on any Security in permanent global 
form shall be made to the Person or Persons specified therein.

         Notwithstanding the provisions of Section 308 and except as provided
in the preceding paragraph, the Company, the Trustee and any agent of the
Company and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a permanent global Security (i) in the
case of a permanent global Security in registered form, the Holder of such
permanent global Security in registered form, or (ii) in the case of a permanent
global Security in bearer form, Euroclear or CEDEL.

of or within the series are to be issuable initially in temporary global form
and whether any Securities of or within the series are to be issuable in
permanent global form (with or without coupons) and, if so, whether beneficial
owners of interests in any such permanent global Security may exchange such
interests for Securities of such series and of like tenor of any authorized form
and denomination and the circumstances under which any such exchanges may

such certificates, documents or conditions;

         (21)    if the Securities of or within the series are to be issued
upon the exercise of debt warrants, the time, manner and place for such
Securities to be authenticated and delivered;

         (22)    whether and under what circumstances the Company will pay

adjustment of the applicable conversion or exchange price or rate and any

Securities are convertible or exchangeable; and

         (25)    any other terms of the series (which terms shall not be
inconsistent with the provisions of this Indenture except as permitted by
Section 905).

         All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series, if any, shall be substantially identical
except, in the case of Registered or Bearer Securities issued in global form,
as to denomination and except as may otherwise be provided in or pursuant to
such Board Resolution or in any indenture supplemental hereto.  All Securities
of any one series need not be issued at the same time and, unless otherwise
provided, a series may be reopened, without the consent of the Holders, for
issuances of additional Securities of such series.

         If any of the terms of the Securities of any series are established by
action taken pursuant to one or more Board Resolutions, a copy of an
appropriate record of such action(s) shall be certified by the Secretary or an
Assistant Secretary of the Company and delivered to the Trustee at or prior to
the delivery of the Company Order for authentication and delivery of such
Securities.

         SECTION 302.     Denominations.

         The Securities of each series shall be issuable in such denominations
as shall be specified as contemplated by Section 301.  With respect to
Securities of any series denominated in Dollars, in the absence of any such
provisions with respect to the Securities of any series, the Registered
Securities of such series, other than Registered Securities issued in global
form (which may be of any denomination), shall be issuable in denominations of
$1,000 and any integral multiple thereof and the Bearer Securities of such
series other than Bearer Securities issued in global form (which may be of any
denomination), shall be issuable in denominations of $5,000.

         SECTION 303.     Execution, Authentication, Delivery and Dating.

         The Securities and any coupons appertaining thereto shall be executed
on behalf of the Company by its President or a Vice President, under its
corporate seal reproduced thereon, and attested by its Secretary or an
Assistant Secretary.  The signature of any of these officers on the Securities
and coupons may be manual or facsimile signatures of the present or any future
such authorized officer and may be imprinted or otherwise reproduced on the
Securities.

         Securities or coupons appertaining thereto bearing the manual or
facsimile signatures of individuals who were at any time the proper officers of
the Company shall bind the Company, notwithstanding that such individuals or
any of them have ceased to hold such offices prior to the authentication and
delivery of such Securities or did not hold such offices at the date of such
Securities or coupons.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series, together with
any coupon appertaining thereto, executed


                                      20

<PAGE>   28

by the Company to the Trustee for authentication, together with a Company Order
for the authentication and delivery of such Securities, and the Trustee in
accordance with the Company Order shall authenticate and deliver such
Securities; provided, however, that, in connection with its original issuance,
no Bearer Security shall be mailed or otherwise delivered to any location in
the United States; and provided further that, unless otherwise specified with
respect to any series of Securities pursuant to Section 301 a Bearer Security
may be delivered in connection with its original issuance only if the Person
entitled to receive such Bearer Security shall have furnished a certificate to
Euroclear or CEDEL, as the case may be, in the form set forth in Exhibit A-1 to
this Indenture or such other certificate as may be specified with respect to
any series of Securities pursuant to Section 301, dated no earlier than 15 days
prior to the earlier of the date on which such Bearer Security is delivered and
the date on which any temporary Security first becomes exchangeable for such
Bearer Security in accordance with the terms of such temporary Security and
this Indenture.  Except as permitted by Section 306, the Trustee shall not
authenticate and deliver any Bearer Security unless all appurtenant coupons for
interest then matured have been detached and canceled.

   
         If all of the Securities of any series are not to be issued at one time
and if the Board Resolution or supplemental indenture establishing such series
shall so permit, such Company Order may set forth procedures acceptable to the
Trustee for the issuance of such Securities and determining the terms of
particular Securities of such series, such as interest rate or formula, maturity
date, date of issuance and date from which interest shall accrue.  In
authenticating Securities, and accepting the additional responsibilities under
this Indenture in relation to such Securities, the Trustee shall be entitled to
receive, and (subject to Section 612 and TIA Section 315(a) through 315(d))
shall be fully protected in conclusively relying upon:
    

         (i)     an Opinion of Counsel complying with Section 102 and stating
                 that:

                 (a)      the form or forms of such Securities and any coupons
                 have been, or will have been upon compliance with such
                 procedures as may be specified therein, established in
                 conformity with the provisions of this Indenture;

                 (b)      the terms of such Securities and any coupons have
                 been, or will have been upon compliance with such procedures
                 as may be specified therein, established in conformity with
                 the provisions of this Indenture; and

                 (c)      such Securities, together with any coupons
                 appertaining thereto, when completed pursuant to such
                 procedures as may be specified therein, and executed and
                 delivered by the Company to the Trustee for authentication in
                 accordance with this Indenture, authenticated and delivered by
                 the Trustee in accordance with this Indenture and issued by
                 the Company in the manner and subject to any conditions
                 specified in such Opinion of Counsel, will constitute legal,
                 valid and binding obligations of the Company, enforceable in
                 accordance with their terms, subject to applicable bankruptcy,
                 insolvency, reorganization and other similar laws of general
                 applicability relating to or affecting the enforcement of
                 creditors' rights generally and to general equitable
                 principles and to such other matters as may be specified
                 therein; and

   
                 (d)      the issuance of such Securities and any coupons will
                 not contravene the articles of incorporation or bylaws of the
                 Company or result in any violation of any of the terms or
                 provisions of any law or regulation or of any indenture,
                 mortgage or other agreement known to such counsel by which the
                 Company is bound; and
    


                                      21

<PAGE>   29

         (ii)    an Officers' Certificate complying with Section 102 and
stating that all conditions precedent provided for in this Indenture relating
to the issuance of such Securities have been, or will have been upon compliance
with such procedures as may be specified therein, complied with and that, to
the best of the knowledge of the signers of such certificate, no Event of
Default with respect to such Securities shall have occurred and be continuing.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all the Securities of any series are not to be issued at one
time, it shall not be necessary to deliver a Company Order, an Opinion of
Counsel or an Officers' Certificate otherwise required pursuant to the
preceding paragraph at the time of issuance of each Security of such series,
but such order, opinion and certificate, with appropriate modifications to
cover such future issuances, shall be delivered at or before the time of
issuance of the first Security of such series.

         The Trustee shall not be required to authenticate such Securities if
the issue of such Securities pursuant to this Indenture will affect the
Trustee's own rights, duties, obligations or immunities under the Securities
and this Indenture or otherwise in a manner which is not reasonably acceptable
to the Trustee.

         Each Registered Security shall be dated the date of its authentication
and each Bearer Security shall be dated as of the date specified as
contemplated by Section 301.

         No Security or coupon appertaining thereto shall be entitled to any
benefit under this Indenture or be valid or obligatory for any purpose unless
there appears on such Security or the Security to which such coupon appertains
a certificate of authentication substantially in the form provided for herein
duly executed by the Trustee by manual signature of an authorized officer, and
such certificate upon any Security shall be conclusive evidence,and the only
evidence, that such Security has been duly authenticated and delivered
hereunder and is entitled to the benefits of this Indenture.  Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section
309 together with a written statement (which need not comply with Section 102
and need not be accompanied by an Opinion of Counsel) stating that such
Security has never been issued or sold by the Company, for all purposes of this
Indenture such Security shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits of this
Indenture.

         SECTION 304.     Temporary Securities.

         (a)     Pending the preparation of definitive Securities of any
series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Securities which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu
of which they are issued, in registered form, or, if authorized, in bearer form
with one or more coupons or without coupons, and with such appropriate
insertions, omissions, substitutions and other variations as the officers of
the Company executing such Securities may determine, as conclusively evidenced
by their execution of such Securities.  In the case of Securities of any
series, such temporary Securities may be in global form.

         Except in the case of temporary Securities in global form


                                      22

<PAGE>   30

(which shall be exchanged in accordance with Section 304(b) or as otherwise
provided in or pursuant to a Board Resolution), if temporary Securities of any
series are issued, the Company will cause definitive Securities of that series
to be prepared without unreasonable delay.  After the preparation of definitive
Securities of such series, the temporary Securities of such series shall be
exchangeable for definitive Securities of such series upon surrender of the
temporary Securities of such series at the office or agency of the Company in a
Place of Payment for that series, without charge to the Holder.  Upon surrender
for cancellation of any one or more temporary Securities of any series
(accompanied by any non-matured coupons appertaining thereto), the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of the same series of
authorized denominations; provided, however, that no definitive Bearer Security
shall be delivered in exchange for a temporary Registered Security; and
provided further that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in Section 303.  Until so exchanged, the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series.

   
         (b)     Unless otherwise provided as contemplated in Section 301, this
Section 304(b) shall govern the exchange of temporary Securities issued in
global form other than through the facilities of DTC.  If any such temporary
Security is issued in global form, then such temporary global Security shall,
unless otherwise provided therein, be delivered to the London, England office of
a depository or common depository (the "Common Depository"), for the benefit of
Euroclear and CEDEL.
    

         Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in an aggregate principal amount equal to the principal
amount of such temporary global Security, executed by the Company.  On or after
the Exchange Date, such temporary global Security shall be surrendered by the
Common Depository to the Trustee, as the Company's agent for such purpose, to
be exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary global Security, an equal aggregate principal
amount of definitive Securities of or within the same series of authorized
denominations and of like tenor as the portion of such temporary global
Security to be exchanged.  The definitive Securities to be delivered in
exchange for any such temporary global Security shall be in bearer form,
registered form, permanent global bearer form or permanent global registered
form, or any combination thereof, as specified as contemplated by Section 301,
and, if any combination thereof is so specified, as requested by the beneficial
owner thereof; provided, however, that, unless otherwise specified in such
temporary global Security, upon such presentation by the Common Depository,
such temporary global Security is accompanied by a certificate dated the
Exchange Date or a subsequent date and signed by Euroclear as to the portion of
such temporary global Security, if any, held for its account then to be
exchanged and a certificate dated the Exchange Date or a subsequent date and
signed by CEDEL as to the portion of such temporary global Security, if any,
held for its account then to be exchanged, each in the form set forth in
Exhibit A-2 to this Indenture or in such other form as may be established
pursuant to Section 301; and provided further that definitive Bearer Securities
shall be delivered in exchange for a portion of a temporary global Security
only in compliance


                                      23

<PAGE>   31
with the requirements of Section 303.

        Unless otherwise specified in such temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged for definitive Securities of the same series and of
like tenor following the Exchange Date when the account holder instructs
Euroclear or CEDEL, as the case may be, to request such exchange on his behalf
and delivers to Euroclear or CEDEL, as the case may be, a certificate in the
form set forth in Exhibit A-1 to this Indenture (or in such other form as may
be established pursuant to Section 301), dated no earlier than 15 days prior to
the Exchange Date, copies of which certificate shall be available from the
offices of Euroclear or CEDEL, the Trustee, any Authenticating Agent appointed
for such series of Securities and each Paying Agent.  Unless otherwise
specified in such temporary global Security, any such exchange shall be made
free of charge to the beneficial owners of such temporary global Security,
except that a Person receiving definitive Securities must bear the cost of
insurance, postage, transportation and the like unless such Person takes
delivery of such definitive Securities in person at the offices of Euroclear
or CEDEL.  Definitive Securities in bearer form to be delivered in exchange for
any portion of a temporary global Security shall be delivered only outside the
United States.

        Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary
global Security on an Interest Payment Date for Securities of such series
occurring prior to the applicable Exchange Date shall be payable to Euroclear
or CEDEL on such Interest Payment Date upon delivery by Euroclear or CEDEL to
the Trustee of a certificate or certificates in the form set forth in Exhibit
A-2 to this Indenture (or in such other forms as may be established pursuant to
Section 301), for credit without further interest on or after such Interest
Payment Date to the respective accounts of Persons who are the beneficial
owners of such temporary global Security on such Interest Payment Date and who
have each delivered to Euroclear or CEDEL, as the case may be, a certificate
dated no earlier than 15 days prior to the Interest Payment Date occurring
prior to such Exchange Date in the form set forth as Exhibit A-1 to this
Indenture (or in such other forms as may be established pursuant to Section
301).  Notwithstanding anything to the contrary herein contained, the
certifications made pursuant to this paragraph shall satisfy the certification
requirements of the preceding two paragraphs of this Section 304(b) and of the
third paragraph of Section 303 of this Indenture and the interests of the
Persons who are the beneficial owners of the temporary global Security with
respect to which such certification was made will be exchanged for definitive
Securities of the same series and of like tenor on the Exchange Date or the
date of certification if such date occurs after the Exchange Date, without
further act or deed by such beneficial owners.  Except as otherwise provided in
this paragraph, no payments of principal or interest owing with respect to a
beneficial interest in a temporary global Security will be made unless and
until such interest in such temporary global Security shall have been exchanged
for an interest in a definitive Security.  Any interest so received by
Euroclear or CEDEL and not paid as herein provided shall be returned to the
Trustee prior to the expiration of two years after such Interest Payment Date
in order to be repaid to the Company.

                                      24

<PAGE>   32

         The Company shall cause to be kept at the Corporate Trust Office of
the Trustee or in any office or agency of the Company in a Place of Payment a
register for each series of Securities (the registers maintained in such office
or in any such office or agency of the Company in a Place of Payment being
herein sometimes referred to collectively as the "Security Register") in which,
subject to such reasonable regulations as it or the Security Registrar may 
prescribe, the Company shall provide for the registration of Registered
Securities and of transfers of Registered Securities.  The Security Register
shall be in written form or any other form capable of being converted into
written form within a reasonable time.  The Trustee, at its Corporate Trust
Office, is hereby initially appointed "Security Registrar" for the purpose of
registering Registered Securities and transfers of Registered Securities on
such Security Register as herein provided.  In the event that the Trustee shall
cease to be Security Registrar, it shall have the right to examine the Security
Register at all reasonable times and to require that a copy of the Security
Register in written form be delivered to it from time to time as reasonably
requested.

         Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Company in a Place of Payment for that series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities
of the same series, of any authorized denominations and of a like aggregate
principal amount, bearing a number not contemporaneously outstanding, and
containing identical terms and provisions.

        Subject to the provisions of this Section 305, at the option of the
Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency.  Whenever any such Registered
Securities are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Registered Securities which the
Holder making the exchange is entitled to receive.  Unless otherwise specified
with respect to any series of Securities as contemplated by Section 301, Bearer
Securities may not be issued in exchange for Registered Securities.

        If (but only if) permitted as contemplated by Section 301, at the
option of the Holder, Bearer Securities of any series may be exchanged for
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining.  If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds
acceptable to the Company in an amount equal to the face amount of such missing
coupon or coupons, or the surrender of such missing coupon or coupons may be
waived by the Company and the Trustee if there is furnished to them such
security or indemnity as they may require to save each of them and any Paying
Agent harmless.  If thereafter the Holder of such Security shall surrender to
any Paying Agent any such missing coupon in respect of which such a payment
shall have been made, such Holder shall be entitled to receive the amount of 
such payment; provided, however, that, except as otherwise provided in Section 
1002, interest represented by coupons shall be payable only upon presentation 
and


                                      25

<PAGE>   33

surrender of those coupons at an office or agency located outside the
United States.  Notwithstanding the foregoing, in case a Bearer Security of any
series is surrendered at any such office or agency in a permitted exchange for
a Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at
such office or agency on the related proposed date for payment of Defaulted
Interest, such Bearer Security shall be surrendered without the coupon relating
to such Interest Payment Date or proposed date for payment, as the case may be,
and interest or Defaulted Interest, as the case may be, will not be payable on
such Interest Payment Date or proposed date for payment, as the case may be,
in respect of the Registered Security issued in exchange for such Bearer
Security, but will be payable only to the Holder of such coupon when due in
accordance with the provisions of this Indenture. Whenever any Securities are
so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the holder making the exchange
is entitled to receive.

        Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be
exchangeable only as provided in this paragraph.  If the depository for any
permanent global Security is DTC, then, unless the terms of such global
Security expressly permit such global Security to be exchanged in whole or in
part for definitive Securities, a global Security may be transferred, in whole
but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to
a successor to DTC for such global Security selected or approved by the Company
or to a nominee of such successor to DTC.  If at any time DTC notifies the
Company that it is unwilling or unable to continue as depository for the
applicable global Security or Securities or if at any time DTC ceases to be a
clearing agency registered under the Exchange Act if so required by applicable
law or regulation, the Company shall appoint a successor depository with
respect to such global Security or Securities.  If (x) a successor depository
for such global Security or Securities is not appointed by the Company within
90 days after the Company receives such notice or becomes aware of such
unwillingness, inability or ineligibility, (y) an Event of Default has occurred
and is continuing and the beneficial owners representing a majority in
principal amount of the applicable series of Securities represented by such
global Security or Securities advise DTC to cease acting as depository for such
global Security or Securities or (z) the Company, in its sole discretion,
determines at any time that all Outstanding Securities (but not less than all)
of any series issued or issuable in the form of one or more global Securities
shall no longer be represented by such global Security or Securities (provided,
however, the Company may not make such determination during the 40-day
restricted period provided by Regulation S under the Securities Act or during
any other similar period during which the Securities must be held in global
form as may be required by the Securities Act), then the Company shall execute,
and the Trustee shall authenticate and deliver definitive Securities of like
series, rank, tenor and terms in definitive form in an aggregate principal
amount equal to the principal amount of such global Security or Securities.  If
any beneficial owner of an interest in a permanent global Security is otherwise
entitled to exchange such an interest for Securities of such series and of like
tenor and principal amount of another authorized form and denomination, as
specified as contemplated by Section 301 and provided that any applicable
notice provided in the permanent global Security shall have been given, then
without unnecessary delay but in any event not later than the earliest date on
which


                                      26

<PAGE>   34

such interest may be so exchanged, the Company shall execute, and the
Trustee shall authenticate and deliver definitive Securities in aggregate
principal amount equal to the principal amount of such beneficial owner's
interest in such permanent global Security.  On or after the earliest date on
which such interests may be so exchanged, such permanent global Security shall
be surrendered for exchange by DTC or such other depository as shall be
specified in the Company Order with respect thereto to the Trustee, as the
Company's agent for such purpose; provided, however, that no such exchanges may
occur during a period beginning at the opening of business 15 days before any
selection of Securities to be redeemed and ending on the relevant Redemption
Date if the Security for which exchange is requested may be among those
selected for redemption; and provided further that no Bearer Security delivered
in exchange for a portion of a permanent global Security shall be mailed or
otherwise delivered to any location in the United States. If a Registered
Security is issued in exchange for any portion of a permanent global Security
after the close of business at the office or agency where such exchange occurs
on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of such Registered
Security, but will be payable on such Interest Payment Date or proposed date
for payment, as the case may be, only to the Person to whom interest in respect
of such portion of such permanent global Security is payable in accordance with
the provisions of this Indenture.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Security Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any transfer.

         The Company or the Trustee, as applicable, shall not be required (i)
to issue, register the transfer of or exchange any Security if such Security
may be among those selected for redemption during a period beginning at the
opening of business 15 days before selection of the Securities to be redeemed
under Section 1103 and ending at the close of business on (A) if such
Securities are issuable only as Registered Securities, the day of the mailing
of the relevant notice of redemption and (B) if such Securities are issuable as
Bearer Securities, the day of the first publication of the relevant notice of
redemption or, if such Securities are also issuable as Registered Securities
and there is no publication, the mailing of the relevant notice of redemption,
or (ii) to register the transfer of or exchange any Registered Security so
selected for redemption in whole or in part, except, in


                                      27

<PAGE>   35

the case of any Registered Security to be redeemed in part, the portion
thereof not to be redeemed, or (iii) to exchange any Bearer Security so
selected for redemption except that such a Bearer Security may be exchanged for
a Registered Security of that series and like tenor, provided that such
Registered Security shall be simultaneously surrendered for redemption, or (iv)
to issue or to register the transfer or exchange of any Security which has been
surrendered for repayment at the option of the Holder, except the portion, if
any, of such Security not to be so repaid.

         SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security or a Security with a mutilated coupon
appertaining to it is surrendered to the Trustee or the Company, together with
such security or indemnity as may be required by the Company or the Trustee to
save each of them or any agent of either of them harmless, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and principal amount, containing identical
terms and provisions and bearing a number not contemporaneously outstanding,
with coupons corresponding to the coupons, if any, appertaining to the
surrendered Security.

         If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security or coupon, and (ii) such security or indemnity as may be required by
them to save each of them and any agent of either of them harmless, then, in
the absence of actual notice to the Company or the Trustee that such Security or
coupon has been acquired by a bona fide purchaser, the Company shall execute
and upon its request the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security or in exchange for the Security to
which a destroyed, lost or stolen coupon appertains (with all appurtenant
coupons not destroyed, lost or stolen), a new Security of the same series and
principal amount, containing identical terms and provisions and bearing a
number not contemporaneously outstanding, with coupons corresponding to the
coupons, if any, appertaining to such destroyed, lost or stolen Security or to
the Security to which such destroyed, lost or stolen coupon appertains.

         Notwithstanding the provisions of the previous two paragraphs, in case
any such mutilated, destroyed, lost or stolen Security or coupon has become or
is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, with coupons corresponding to coupons, if any,
appertaining to such destroyed, lost or stolen Security or to the Security to
which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon; provided, however, that payment of principal of (and premium or
Make-Whole Amount, if any), any interest on and any Additional Amounts with
respect to Bearer Securities shall, except as otherwise provided in Section
1002, be payable only at an office or agency located outside the United States
and, unless otherwise specified as contemplated by Section 301, any interest on
Bearer Securities shall be payable only upon presentation and surrender of the
coupons appertaining thereto.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or


                                      28

<PAGE>   36

stolen Security, or in exchange for a Security to which a destroyed, lost or
stolen coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen
Security and its coupons, if any, or the destroyed, lost or stolen coupon shall
be at any time enforceable by anyone, and shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Securities
of that series and their coupons, if any, duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities or
coupons.

         SECTION 307.     Payment of Interest; Interest Rights Preserved.

         Except as otherwise specified with respect to a series of Securities
in accordance with the provisions of Section 301, interest on any Registered
Security that is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name that Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest at the office or agency of the
Company maintained for such purpose pursuant to Section 1002; provided,
however, that each installment of interest on any Registered Security may at
the Company's option be paid by (i) mailing a check for such interest, payable
to or upon the written order of the Person entitled thereto pursuant to Section
308, to the address of such Person as it appears on the Security Register or
(ii) transfer to an account maintained by the payee located inside the United
States.

         Unless otherwise provided as contemplated by Section 301 with respect
to the Securities of any series, payment of interest may be made, in the case
of a Bearer Security, by transfer to an account maintained by the payee with a
bank located outside the United States.

         Unless otherwise provided as contemplated by Section 301, every
permanent global Security will provide that interest, if any, payable on any
Interest Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case
may be, with respect to that portion of such permanent global Security held for
its account by DTC, Euroclear or CEDEL, as the case may be, for the purpose of
permitting such party to credit the interest received by it in respect of such
permanent global Security to the accounts of the beneficial owners thereof.

         In case a Bearer Security of any series is surrendered in exchange for
a Registered Security of such series after the close of business (at an office
or agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next
succeeding Interest Payment Date, such Bearer Security shall be surrendered
without the coupon relating to such Interest Payment Date and interest will not
be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but will be payable only to the
Holder of such coupon when due in accordance with the provisions of this
Indenture.

         Except as otherwise specified with respect to a series of Securities
in accordance with the provisions of Section 301, any interest on any
Registered Security of any series that is payable, but is not punctually paid
or duly provided for, on any Interest Payment Date (herein called "Defaulted
Interest") shall forthwith


                                      29

<PAGE>   37

cease to be payable to the registered Holder thereof on the relevant Regular
Record Date by virtue of having been such Holder, and such Defaulted Interest
may be paid by the Company, at its election in each case, as provided in clause
(1) or (2) below:

   
         (1)     The Company may elect to make payment of any Defaulted Interest
to the Persons in whose names the Registered Securities of such series (or
their respective Predecessor Securities) are registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest,
which shall be fixed in the following manner.  The Company shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on
each Registered Security of such series and the date of the proposed payment
(which shall not be less than 20 days after such notice is received by the
Trustee), and at the same time the Company shall deposit with the Trustee an
amount of money in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) equal to the aggregate amount proposed to be paid in
respect of such Defaulted Interest or shall make arrangements satisfactory to
the Trustee for such deposit on or prior to the date of the proposed payment,
such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Interest as in this clause provided.  Thereupon the
Trustee shall fix a Special Record Date for the payment of such Defaulted
Interest which shall be not more than 15 days and not less than 10 days prior
to the date of the proposed payment and not less than 10 days after the receipt
by the Trustee of the notice of the proposed payment.  The Trustee shall
promptly notify the Company of such Special Record Date and, in the name and at
the expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be mailed,
first-class postage prepaid, to each Holder of Registered Securities of such
series at such Holder's address as it appears in the Security Register not less
than 10 days prior to such Special Record Date.  Notice of the proposed payment
of such Defaulted Interest and the Special Record Date therefor having been
mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in
whose names the Registered Securities of such series (or their respective
Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause (2).
In case a Bearer Security of any series is surrendered at the office or agency
in a Place of Payment for such series in exchange for a Registered Security of
such series after the close of business at such office or agency on any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, such Bearer Security
shall be surrendered without the coupon relating to such proposed date of
payment and Defaulted Interest will not be payable on such proposed date of
payment in respect of the Registered Security issued in exchange for such Bearer
Security, but will be payable only to the Holder of such coupon when due in
accordance with the provisions of this Indenture.
    

         (2)     The Company may make payment of any Defaulted Interest on the
Registered Securities of any series in any other lawful manner not inconsistent
with the requirements of any securities exchange on which such Securities may
be listed, and upon such notice as may be required by such exchange, if, after
notice given by the Company


                                      30

<PAGE>   38

to the Trustee of the proposed payment pursuant to this clause, such manner of
payment shall be deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section and Section 305,
each Security delivered under this Indenture upon registration of transfer of
or in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

         Subject to the provisions of Section 1402 and except as otherwise
specified with respect to a series of Securities in accordance with the
provisions of Section 301, in the case of any Security which is converted or
exchanged after any Regular Record Date and on or prior to the next succeeding
Interest Payment Date (other than any Security, the principal of (or premium, if
any, on) which shall become due and payable, whether at a Stated Maturity or by
declaration of acceleration, call for redemption, or otherwise, prior to such
Interest Payment Date), interest whose Stated Maturity is on such Interest
Payment Date shall be payable on such Interest Payment Date notwithstanding such
conversion or exchange, and such interest (whether or not punctually paid or
duly provided for) shall be paid to the Person in whose name that Security (or
one or more Predecessor Securities) is registered at the close of business on
such Regular Record Date. Except as otherwise expressly provided in the
immediately preceding sentence, in the case of any Security which is converted
or exchanged, interest whose Stated Maturity is after the date of conversion or
exchange of such Security shall not be payable.

         SECTION 308.     Persons Deemed Owners.

         Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as
the owner of such Security for the purpose of receiving payment of principal of
(and premium or Make-Whole Amount, if any), and (subject to Sections 305 and
307) interest on, such Registered Security and for all other purposes
whatsoever, whether or not such Registered Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

         Title to any Bearer Security and any coupons appertaining thereto
shall pass by delivery.  The Company, the Trustee and any agent of the Company
or the Trustee may treat the Holder of any Bearer Security and the Holder of
any coupon as the absolute owner of such Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupon be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

         None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

         Notwithstanding the foregoing, with respect to any global Security,
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 any depository, as a Holder, with respect
to such global Security or impair, as between such depository and owners of
beneficial interests in such global Security, the operation of customary
practices governing the exercise of the rights of such depository (or its
nominee) as Holder of such global Security.

         SECTION 309.     Cancellation.

         All Securities and coupons surrendered for payment, redemption,
repayment at the option of the Holder, registration of transfer or exchange or
for credit against any sinking fund payment shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee, and any such
Securities and coupons and Securities and coupons surrendered directly to the
Trustee for any such purpose shall be promptly canceled by it.  The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in
any manner whatsoever, and may deliver to the Trustee (or to any other Person
for delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder which the Company has not issued and sold, and all
Securities so delivered shall be promptly canceled by the Trustee.  If the
Company shall so acquire any of the Securities, however, such acquisition


                                      31

<PAGE>   39

shall not operate as a redemption or satisfaction of the indebtedness
represented by such Securities unless and until the same are surrendered to the
Trustee for cancellation.  No Securities shall be authenticated in lieu of or
in exchange for any Securities canceled as provided in this Section, except as
expressly permitted by this Indenture.  Cancelled Securities and coupons held
by the Trustee shall be destroyed by the Trustee and, if required in writing by
the Company, the Trustee shall deliver a certificate of such destruction to the
Company, unless by a Company Order the Company directs their return to it.

         SECTION 310.     Computation of Interest.

         Except as otherwise specified as contemplated by Section 301 with
respect to Securities of any series, interest on the Securities of each series
shall be computed on the basis of a 360-day year consisting of twelve 30-day
months.

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

         SECTION 401.     Satisfaction and Discharge of Indenture.

         This Indenture shall upon Company Request cease to be of further
effect with respect to any series of Securities specified in such Company
Request (except as to any surviving rights of registration of transfer or
exchange of Securities of such series herein expressly provided for and any
right to receive Additional Amounts, as provided in Section 1011), and the
Trustee, upon receipt of a Company Order, and at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture as to such series when

         (1)     either

                 (A)      all Securities of such series theretofore
                 authenticated and delivered and all coupons, if any,
                 appertaining thereto (other than (i) coupons appertaining to
                 Bearer Securities surrendered for exchange for Registered
                 Securities and maturing after such exchange, whose surrender
                 is not required or has been waived as provided in Section 305,
                 (ii) Securities and coupons of such series which have been
                 destroyed, lost or stolen and which have been replaced or paid

                 Securities called for redemption and maturing after the
                 relevant Redemption Date, whose surrender has been waived as
                 provided in Section 1106, and (iv) Securities and coupons of
                 such series for whose payment money has theretofore been
                 deposited in trust or segregated and held in trust by the
                 Company and thereafter repaid to the Company or discharged
                 from such trust, as provided in Section 1003) have been
                 delivered to the Trustee for cancellation; or

                 (B)      all Securities of such series and, in the case of (i)
                 or (ii) below, any coupons appertaining thereto not
                 theretofore delivered to the Trustee for cancellation

                          (i)     have become due and payable, or

                          (ii)    will become due and payable at their Stated
                                  Maturity within one year, or

                          (iii)   if redeemable at the option of the Company,
                                  are to be called for redemption within one
                                  year under arrangements

                                  notice of redemption by the Trustee in the
                                  name, and at the expense, of the Company,

                 and the Company, in the case of (i), (ii) or (iii)
                 above, has irrevocably deposited or caused to be deposited
                 with the Trustee as trust funds in trust for the purpose an
                 amount in the currency or currencies, currency unit or units
                 or composite currency or currencies in which the Securities of
                 such series are payable, sufficient to pay and discharge the
                 entire indebtedness on such Securities and such coupons not
                 theretofore delivered to the Trustee for cancellation, for
                 principal (and premium or Make-Whole Amount, if any) and
                 interest, and any Additional Amounts with respect thereto, to
                 the date of such deposit (in the case of Securities which have
                 become due and payable) or the Stated Maturity or Redemption
                 Date, as the case may be;

         (2)     The Company has paid or caused to be paid all or other sums
payable hereunder by the Company; and

         (3)     The Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of
this Indenture as to such series have been complied with.

Section 606, the obligations of the Company to any Authenticating Agent under
Section 611 and, if money shall have been deposited with and held by the
Trustee pursuant to subclause (B) of clause (1) of this Section, the
obligations of the Trustee under Section 402 and the last paragraph of Section
1003, shall survive.

         In the event that there are Securities of two or more series
outstanding hereunder, the Trustee shall be required to execute an instrument
acknowledging satisfaction and discharge of this Indenture only if requested to
do so with respect to Securities of a particular series as to which it is
Trustee and if the other conditions thereto are met.

         SECTION 402.     Application of Trust Funds.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities, the
coupons and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium or Make-Whole Amount, if any), and any interest and Additional Amounts
for whose payment such money has been deposited with or received by the
Trustee, but such money need not be segregated from other funds except to the
extent required by law.

Company is directly responsible or liable as obligor or guarantor), having a
principal amount outstanding in excess of $10,000,000 (other than indebtedness
which is non-recourse to the Company or the Subsidiaries), whether such
indebtedness now exists or shall hereafter be created, which default shall have
resulted in such indebtedness being declared due and payable prior to the date
on which it would otherwise have become due and payable, without such
indebtedness having been discharged, or such acceleration having been rescinded
or annulled, within a period of 30 days after there shall have been given, by

                 (B)      appoints a Custodian of the Company or any

U.S. Code or any similar Federal or state law for the relief of debtors and the
term "Custodian" means any receiver, trustee, assignee, liquidator or other
similar official under any Bankruptcy Law.

         SECTION 502.   Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in aggregate principal amount of the
Outstanding Securities of each such affected series (voting as a single class)
may declare the principal (or, if any Securities are Original Issue Discount
Securities or Indexed Securities, such portion of the principal as may be
specified in the terms thereof) of, and the Make-Whole Amount, if any, on, all
the Securities of that series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by the Holders), and upon
any such declaration such principal or specified portion thereof shall become
immediately due and payable.

         At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in
this Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

         (1)     the Company has paid or deposited with the Trustee a sum
sufficient to pay in the currency, currency unit or composite currency in which
the Securities of such series is payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series):

                 (A)      all overdue installments of interest on and any
                          Additional Amounts payable in respect of all
                          Outstanding Securities of that series and any


                                      35

<PAGE>   43

                          related coupons;

                 (B)      the principal of (and premium or Make-Whole Amount,
                          if any, on) any Outstanding Securities of that series
                          which have become due otherwise than by such
                          declaration of acceleration and interest thereon at
                          the rate or rates borne by or provided for in such
                          Securities;

                 (C)      to the extent that payment of such interest is
                          lawful, interest upon overdue installments of
                          interest and any Additional Amounts at the rate or
                          rates borne by or provided for in such Securities;
                          and

                 (D)      all sums paid or advanced by the Trustee hereunder
                          and the reasonable compensation, expenses,
                          disbursements and advances of the Trustee, its agents
                          and counsel; and

         (2)     all Events of Default with respect to Securities of that
series, other than the nonpayment of the principal of (or premium or Make-Whole
Amount, if any) or interest on Securities of that series which have become due
solely by such declaration of acceleration, have been cured or waived as
provided in Section 513.

         No such rescission shall affect any subsequent default or impair any
right consequent thereon.

         SECTION 503.    Collection of Indebtedness and Suits for Enforcement 
                         by Trustee.

         The Company covenants that if:

         (1)     default is made in the payment of any installment of interest
or Additional Amounts, if any, on any Security of any series and any related
coupon when such interest or Additional Amount becomes due and payable and such
default continues for a period of 30 days, or

         (2)     default is made in the payment of the principal of (or premium
or Make-Whole Amount, if any, on) any Security of any series at its Maturity,

then the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities of such series and coupons, the whole
amount then due and payable on such Securities and coupons for principal (and
premium or Make-Whole Amount, if any) and interest and Additional Amounts, with
interest upon any overdue principal (and premium or Make-Whole Amount, if any)
and, to the extent that payment of such interest shall be legally enforceable,
upon any overdue installments of interest or Additional Amounts, if any, at the
rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute
a judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities of such series
and collect the moneys adjudged or decreed to be payable in the manner provided
by law out of the property of the Company or any other obligor upon such
Securities of such series, wherever


                                      36

<PAGE>   44


situated.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series
and any related coupons by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.

         SECTION 504.     Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
of any series shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of overdue principal, premium or
Make-Whole Amount, if any, or interest) shall be entitled and empowered, by
intervention in such proceeding or otherwise:

         (i)     to file and prove a claim for the whole amount, or such lesser
amount as may be provided for in the Securities of such series, of principal
(and premium or Make-Whole Amount, if any) and interest and Additional Amounts,
if any, owing and unpaid in respect of the Securities and to file such other
papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel)
and of the Holders allowed in such judicial proceeding, and

         (ii)    to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or
other similar official) in any such judicial proceeding is hereby authorized by
each Holder of Securities of such series and coupons to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee and any predecessor Trustee, their agents and counsel, and any other
amounts due the Trustee or any predecessor Trustee under Section 606.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a
Security or coupon any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or coupons or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder of a Security or coupon in any such proceeding.
 
         SECTION 505.    Trustee May Enforce Claims Without Possession of 
                         Securities or Coupons.

         All rights of action and claims under this Indenture or any of the
Securities or coupons may be prosecuted and enforced by the


                                      37

<PAGE>   45

Trustee without the possession of any of the Securities or coupons or the
production thereof in any proceeding relating thereto, and any such proceeding
instituted by the Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment shall, after provision for the
payment of the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, be for the ratable benefit of the Holders
of the Securities and coupons in respect of which such judgment has been
recovered.

         SECTION 506.     Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium
or Make-Whole Amount, if any) or interest and any Additional Amounts, upon
presentation of the Securities or coupons, or both, as the case may be, and the
notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

         FIRST:  To the payment of all amounts due the Trustee and any
                 predecessor Trustee under Section 606,

         SECOND: To the payment of the amounts then due and unpaid upon the
                 Securities and coupons for principal (and premium or
                 Make-Whole Amount, if any) and interest and any Additional
                 Amounts payable, in respect of which or for the benefit of
                 which such money has been collected, ratably, without
                 preference or priority of any kind, according to the aggregate
                 amounts due and payable on such Securities and coupons for
                 principal (and premium or Make-Whole Amount, if any), interest
                 and Additional Amounts, respectively, and

         THIRD:  To the payment of the remainder, if any, to the Company.

         SECTION 507.     Limitation on Suits.

         No Holder of any Security of any series or any related coupon shall
have any right to institute any proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

         (1)     such Holder has previously given written notice to the
Trustee of a continuing Event of Default with respect to the Securities of that
series;

         (2)     the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default in its own
name as Trustee hereunder;

         (3)     such Holder or Holders have offered to the Trustee indemnity
satisfactory to the Trustee against the costs, expenses and liabilities to be
incurred in compliance with such request;

         (4)     the Trustee for 60 days after its receipt of such notice,
request and offer of indemnity has failed to institute any such proceeding; and

         (5)     no direction inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders


                                      38

<PAGE>   46

of a majority in principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all such
Holders.

         SECTION 508.     Unconditional Right of Holders to Receive Principal,
                          Premium or Make-Whole Amount, if any, Interest and
                          Additional Amounts.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security or coupon shall have the right which is absolute and unconditional
to receive payment of the principal of (and premium or Make-Whole Amount, if
any) and (subject to Sections 305 and 307) interest on, and any Additional
Amounts in respect of, such Security or payment of such coupon on the respective
due dates expressed in such Security or coupon (or, in the case of redemption,
on the Redemption Date), to convert or exchange such Securities in accordance
with Article Sixteen and to institute suit for the enforcement of any such
payment, and such rights shall not be impaired without the consent of such
Holder.

         SECTION 509.     Restoration of Rights and Remedies.

         If the Trustee or any Holder of a Security or coupon has instituted
any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case the Company, the Trustee and the Holders of Securities and coupons shall,
subject to any determination in such proceeding, be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee and the Holders shall continue as though no such
proceeding has been instituted.

         SECTION 510.     Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities or coupons in the
last paragraph of Section 306, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders of Securities or coupons is intended
to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

         SECTION 511.     Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Security
or coupon to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or any acquiescence therein. Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be exercised from time
to time, and as often as may be deemed expedient, by the Trustee or by the
Holders of Securities or coupons, as the case may be.


                                      39

<PAGE>   47

         SECTION 512.     Control by Holders of Securities.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee with respect
to the Securities of such series, provided that

         (1)     such direction shall not be in conflict with any rule of law
or with this Indenture,

         (2)     the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction, and

         (3)     the Trustee need not take any action which might involve it in
personal liability or be unduly prejudicial to the Holders of Securities of
such series not joining therein (but the Trustee shall have no obligation as to
the determination of such undue prejudice).

         SECTION 513.     Waiver of Past Defaults.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series and any related coupons consent to the waiver of
any past default hereunder with respect to such series and its consequences,
except a default

         (1)     in the payment of the principal of (or premium or Make-Whole
Amount, if any) or interest on or Additional Amounts payable in respect of any
Security of such series or any related coupons, or

         (2)     in respect of a covenant or provision hereof which under
Article Nine cannot be modified or amended without the consent of the Holder of
each Outstanding Security of such series affected.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

         SECTION 514.     Waiver of Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law
wherever enacted, now or at any time hereafter in force, which may affect the
covenants or the performance of this Indenture; and the Company (to the extent
that it may lawfully do so) hereby expressly waives all benefit or advantage
of any such law, and covenants that it will not hinder, delay or impede the
execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been
enacted.

         SECTION 515.     Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken
or omitted by it as Trustee, the filing by any party litigant in such suit of
an undertaking to pay the costs of such suit, and that such court may

and good faith of the claims or defenses made by such party litigant; but the

Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities,
or to any suit instituted by any Holder for the enforcement of the payment of
the principal of (or premium or Make-Whole Amount, if any) or interest on or

respective Stated Maturities expressed in such Security (or in the case of
redemption, on or after the Redemption Date) or to enforce the right to convert
or exchange any Security in accordance with Article Sixteen.

                                  THE TRUSTEE

         SECTION 601.     Notice of Defaults.

         Within 90 days after the occurrence of any default hereunder with
respect to the Securities of any series, the Trustee shall transmit in the
manner and to the extent provided in TIA Section 313(c), notice of such default
hereunder actually known to a Responsible Officer of the Trustee, unless such
default shall have been cured or waived; provided, however, that, except in the
case of a default in the payment of the principal of (or premium or Make-Whole
Amount, if any) or interest on or any Additional Amounts with respect to any
Security of such series, or in the payment of any sinking fund installment with
respect to the Securities of such series, the Trustee shall be protected in
withholding such notice if and so long as Responsible Officers of the Trustee in
good faith determine that the withholding of such notice is in the interests of
the Holders of the Securities and coupons of such series; and provided further
that in the case of any default or breach of the character specified in Section
501(4) with respect to the Securities and coupons of such series, no such notice
to Holders shall be given until at least 60 days after the occurrence thereof.
For the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default with
respect to the Securities of such series.

         SECTION 602.     Certain Rights of Trustee.

         Subject to the provisions of TIA Section 315(a) through 315(d):

and to have been signed or presented by the proper party or parties;

         (3)     any request or direction of the Company mentioned herein shall

of Directors may be sufficiently evidenced by a Board Resolution;

         (4)     whenever in the administration of this Indenture the


                                      41

<PAGE>   49

Trustee shall deem it desirable that a matter be proved or established prior to
taking, suffering or omitting any action hereunder, the Trustee (unless other
evidence be herein specifically prescribed) may, in the absence of bad faith on
its part, rely upon an Officers' Certificate;

         (5)     the Trustee may consult with counsel and as a condition to the
taking, suffering or omission of any action hereunder may demand an Opinion of
Counsel, and the advice of such counsel or any Opinion of Counsel shall be full
and complete authorization and protection in respect of any action taken,
suffered or omitted by it hereunder in good faith and in reliance thereon;

         (6)     the Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Indenture at the request or direction
of any of the Holders of Securities of any series or any related coupons
pursuant to this Indenture, unless such Holders shall have offered to the
Trustee security or indemnity satisfactory to it against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or
direction;

         (7)     the Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, coupon or other paper or document, but the Trustee, in its
discretion, may make such further inquiry or investigation into such facts or
matters as it may see fit, and, if the Trustee shall determine to make such
further inquiry or investigation, it shall be entitled to examine the books,
records and premises of the Company, personally or by agent or attorney;

         (8)     the Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through agents,
attorneys, custodians or nominees and the Trustee shall not be responsible for
any misconduct or negligence on the part of any agent, attorney, custodian or
nominee appointed with due care by it hereunder; and

         (9)     the Trustee shall not be liable for any action taken, suffered
or omitted by it in good faith and reasonably believed by it to be authorized or
within the discretion or rights or powers conferred upon it by this Indenture.
The Trustee shall not be required to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or indemnity satisfactory to
the Trustee against such risk or liability is not reasonably assured to it.

         SECTION 603.     Not Responsible for Recitals or Issuance of
                          Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificate of authentication, and in any coupons shall be taken as
the statements of the Company, and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

         SECTION 604.     May Hold Securities.

         The Trustee, any Paying Agent, Security Registrar, Authenticating Agent
or any other agent of the Company, in its individual or any other capacity, may
become the owner or pledgee of Securities and coupons and, subject to Section
613 and TIA Sections 310(b) and 311, may otherwise deal with the Company with
the same rights it would have if it were not Trustee, Paying Agent, Security
Registrar, Authenticating Agent or such other agent.

         SECTION 605.     Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on, or investment of, any money received by it
hereunder.

         SECTION 606.     Compensation and Reimbursement.

         The Company agrees:

         (1)     to pay to the Trustee from time to time reasonable
compensation for all services rendered by it hereunder, including extraordinary
services rendered in connection with or during the continuation of a default
hereunder (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust);

         (2)     to reimburse each of the Trustee and any predecessor Trustee
upon its request for all reasonable expenses, disbursements and advances
incurred or made by it in accordance with any provision of this Indenture
(including the reasonable compensation and the expenses and disbursements of its
agents and counsel), except to the extent any such expense, disbursement or
advance may be attributable to its gross negligence or bad faith; and

         (3)     to indemnify each of the Trustee and any predecessor Trustee
and each of their respective directors, officers, agents and employees for, and
to hold each of them harmless against, any loss, liability or  expense, arising
out of or in connection with the acceptance or administration of the trust or
trusts or the performance of its duties hereunder, including the costs and
expenses of defending itself against any claim or liability in connection with
the exercise or performance of any of its powers or duties hereunder except to
the extent any such loss, liability or expense may be attributable to its own
gross negligence or bad faith.

         As security for the performance of the obligations of the Company
under this Section, the Trustee shall have a lien prior to the Securities upon
all property and funds held or collected by the Trustee as such, except funds
held in trust for the payment of principal of (or premium or Make-Whole Amount,
if any) or interest on particular Securities or any coupons.

         When the Trustee incurs expenses or renders services in connection
with an Event of Default described in Section 501(6) and (7), such expenses
(including the fees and expenses of its counsel) and the compensation for such
services are intended to constitute expenses of administration under any
Bankruptcy Law.

         The provisions of this Section shall survive the termination of this
Indenture or the resignation or removal of the Trustee.

         SECTION 607.     Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a
combined capital and surplus of at least $50,000,000 or is a subsidiary of a
corporation which shall be a Person that has a combined capital and surplus of
at least $50,000,000 and which unconditionally guarantees the obligations of
the Trustee


                                      43

<PAGE>   51

hereunder. If such Trustee or Person publishes reports of condition at least
annually, pursuant to law or the requirements of Federal, State, Territorial or
District of Columbia supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such Trustee or Person
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time the Trustee shall cease
to be eligible in accordance with the provisions of this Section, it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article.

         SECTION 608. Resignation and Removal; Appointment of Successor.

         (a)     No resignation or removal of the Trustee and no appointment of
a successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 609.

         (b)     The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If an instrument of acceptance by a successor Trustee shall not have
been delivered to the Trustee within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

         (c)     The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal
amount of the Outstanding Securities of such series delivered to the Trustee
and to the Company.

         (d)     If at any time:

                 (1)      the Trustee shall fail to comply with the provisions
                          of Section 613 or TIA Section 310(b) after written
                          request therefor by the Company or by any Holder of a
                          Security who has been a bona fide Holder of a Security
                          for at least six months, or

                 (2)      the Trustee shall cease to be eligible under Section
                          607 and shall fail to resign after written request
                          therefor by the Company or by any Holder of a
                          Security who has been a bona fide Holder of a
                          Security for at least six months, or

                 (3)      the Trustee shall become incapable of acting or shall
                          be adjudged a bankrupt or insolvent or a receiver of
                          the Trustee or of its property shall be appointed or
                          any public officer shall take charge or control of
                          the Trustee or of its property or affairs for the
                          purpose of rehabilitation, conservation or
                          liquidation,

then, in any such case, (i) the Company by or pursuant to a Board Resolution
may remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security
who has been a bona fide Holder of a Security for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

         (e)     If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of


                                      44

<PAGE>   52


Trustee for any cause with respect to the Securities of one or more series, the
Company, by or pursuant to a Board Resolution, shall promptly appoint a
successor Trustee or Trustees with respect to the Securities of that or those
series (it being understood that any such successor Trustee may be appointed
with respect to the Securities of one or more or all of such series and that at
any time there shall be only one Trustee with respect to the Securities of any
particular series). If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities of such
series delivered to the Company and the retiring Trustee, the successor Trustee
so appointed shall, forthwith upon its acceptance of such appointment, become
the successor Trustee with respect to the Securities of such series and to that
extent supersede the successor Trustee appointed by the Company. If no
successor Trustee with respect to the Securities of any series shall have been
so appointed by the Company or the Holders of Securities and accepted
appointment in the manner hereinafter provided, any Holder of a Security who
has been a bona fide Holder of a Security of such series for at least six
months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to Securities of such series.

         (f)     The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
in the manner provided for notices to the Holders of Securities in Section 106.
Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

         SECTION 609.  Acceptance of Appointment By Successor.

         (a)     In case of the appointment hereunder of a successor Trustee
with respect to all Securities, every such successor Trustee shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on request of
the Company or the successor Trustee, such retiring Trustee shall, upon payment
of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee,
and shall duly assign, transfer and deliver to such successor Trustee all
property and money held by such retiring Trustee hereunder, subject
nevertheless to its claim, if any, provided for in Section 606.

         (b)     In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental hereto, pursuant to Article Nine hereof, wherein each 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, each 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,


                                      45

<PAGE>   53


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 hereunder administered by
any other such Trustee; and upon the execution and delivery of such
supplemental indenture the resignation or removal of the retiring Trustee shall
become effective to the extent provided therein and each such successor
Trustee, without any further act, deed or conveyance, shall become vested with
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; but, on request of the Company or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee
hereunder with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates.

         (c)     Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts
referred to in paragraph (a) or (b) of this Section, as the case may be.

         (d)     No successor Trustee shall accept its appointment unless at
the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article.

         (e)     All monies due and owing to the Trustee shall be paid before
the Successor Trustee takes over.

         SECTION 610.     Merger, Conversion, Consolidation or Succession to
                          Business.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities or coupons shall have
been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and deliver the Securities or coupons so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities or coupons.  In case any Securities or coupons
shall not have been authenticated by such predecessor Trustee, any such
successor Trustee may authenticate and deliver such Securities or coupons, in
either its own name or that of its predecessor Trustee, with the full force and
effect which this Indenture provides for the certificate of authentication of
the Trustee.

         SECTION 611.     Appointment of Authenticating Agent.

         At any time when any of the Securities remain Outstanding, the Trustee
may appoint an Authenticating Agent or Agents with respect to one or more
series of Securities which shall be authorized to act on behalf of the Trustee
to authenticate Securities of such series issued upon exchange, registration of
transfer or partial


                                      46

<PAGE>   54


redemption or repayment thereof or pursuant to Section 306, 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. Any such appointment shall be evidenced by an instrument in writing
signed by a Responsible Officer of the Trustee, a copy of which instrument shall
be promptly furnished to the Company. 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
reasonably acceptable to the Company and, except as may otherwise be provided
pursuant to Section 301, shall at all times be a bank or trust company or
corporation organized and doing business and in good standing under the laws of
the United States of America or of any State or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $25,000,000 and subject to supervision or
examination by Federal or State authorities. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. In case at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or further
act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
such Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of or within the series
with respect to which such Authenticating Agent will serve in the manner set
forth in Section 106. 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 herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

         The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation including reimbursement of its


                                      47

<PAGE>   55


reasonable expenses for its services under this Section.

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

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

         SECTION 612.     Certain Duties and Responsibilities.

         No provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder, or in the exercise of any of its rights or
powers, if it shall have reasonable grounds for believing that repayment of such
funds or indemnity satisfactory to the Trustee against such risk or liability is
not reasonably assured to it. Whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the
provisions of this Section.

         SECTION 613.     Conflicting Interests.

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series. In case an Event of Default shall occur and
be continuing, the Trustee shall exercise such of its rights and powers under
the applicable Indenture and use the same degree of care and skill in their
exercise as a prudent person would exercise or use under the circumstances in
the conduct of his own affairs.

              HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

         SECTION 701.     Disclosure of Names and Addresses of Holders.

         Every Holder of Securities or coupons, by receiving and holding the
same, agrees with the Company and the Trustee that neither the Company nor the
Trustee nor any Authenticating Agent nor any Paying Agent nor any Security
Registrar nor any director, officer, agent or employee of any of them shall be
held accountable by reason of the disclosure of any information as to the names

                CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

         SECTION 801.     Consolidations and Mergers of Company and Sales,
                          Leases and Conveyances Permitted Subject to Certain
                          Conditions.

         The Company may consolidate with, or sell, lease or convey all or
substantially all of its assets to, or merge with or into any other Person,
provided that in any such case, (i) either the Company shall be the continuing
entity, or the successor (if other than the Company) entity shall be a Person
organized and existing under the laws of the United States or a State thereof
and such successor entity shall expressly assume the due and punctual payment of
the principal of (and premium or Make-Whole Amount, if any) and any interest
(including all Additional Amounts, if any, payable pursuant to Section 1011) on
all of the Securities, according to their tenor, the conversion or exchange
rights shall be provided for in accordance with Article Sixteen, if applicable,
or as otherwise specified pursuant to Section 301, and the due and punctual
performance and observance of all of the covenants and conditions of this
Indenture to be performed by the Company by supplemental indenture, complying
with Article Nine hereof, satisfactory to the Trustee, executed and delivered to
the Trustee by such Person and (ii) immediately after giving effect to such
transaction and treating any indebtedness which becomes an obligation of the
Company or any Subsidiary as a


                                      49

result thereof as having been incurred by the Company or such Subsidiary at the
time of such transaction, no Event of Default, and no event which, after notice
or the lapse of time, or both, would become an Event of Default, shall have
occurred and be continuing.

         SECTION 802.     Rights and Duties of Successor Corporation.

         In case of any such consolidation, merger, sale, lease or conveyance
and upon any such assumption by the successor entity, such successor entity
shall succeed to and be substituted for the Company, with the same effect as if
it had been named herein as the party of the first part, and the predecessor
entity, except in the event of a lease, shall be relieved of any further
obligation under this Indenture and the Securities.  Such successor entity
thereupon may cause to be signed, and may issue either in its own name or in
the name of the Company, any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor entity, instead of the Company,
and subject to all the terms, conditions and limitations in this Indenture
prescribed, the Trustee shall authenticate and shall deliver any Securities
which previously shall have been signed and delivered by the officers of the
Company to the Trustee for authentication, and any Securities which such
successor entity thereafter shall cause to be signed and delivered to the
Trustee for that purpose.  All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

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

         SECTION 803.     Officers' Certificate and Opinion of Counsel.

         Any consolidation, merger, sale, lease or conveyance permitted under
Section 801 is also subject to the condition that the Trustee receive an
Officers' Certificate and an Opinion of Counsel to the effect that any such
consolidation, merger, sale, lease or conveyance, and the assumption by any
successor entity, complies with the provisions of this Article and that all
conditions precedent herein provided for relating to such transaction have been
complied with.

         SECTION 901.     Supplemental Indentures Without Consent of Holders.

         Without the consent of any Holders of Securities or coupons, the
Company, when authorized by or pursuant to a Board Resolution, and the Trustee,
at any time and from time to time, may enter into one or more indentures
supplemental hereto, in form satisfactory to the Trustee, for any of the
following purposes:

         (1)     to evidence the succession of another Person to the Company
and the assumption by any such successor of the covenants of the Company herein
and in the Securities contained; or

         (2)     to add to the covenants of the Company for the benefit of


                                      50

<PAGE>   58

the Holders of all or any series of Securities (and, if such covenants are to
be for the benefit of less than all series of Securities, stating that such
covenants are expressly being included solely for the benefit of such series)
or to surrender any right or power herein conferred upon the Company; or

         (3)     to add any additional Events of Default for the benefit of the
Holders of all or any series of Securities (and if such Events of Default are
to be for the benefit of less than all series of Securities, stating that such
Events of Default are expressly being included solely for the benefit of such
series); provided, however, that in respect of any such additional Events of
Default such supplemental indenture may provide for a particular period of
grace after default (which period may be shorter or longer than that allowed in
the case of other defaults) or may provide for an immediate enforcement upon
such default or may limit the remedies available to the Trustee upon such
default or may limit the right of the Holders of a majority in aggregate
principal amount of that or those series of Securities to which such additional
Events of Default apply to waive such default; or

         (4)     to add to or change any of the provisions of this Indenture to
provide that Bearer Securities may be registrable as to principal, to change or
eliminate any restrictions on the payment of principal of or any premium,
Make-Whole Amount or Interest on Bearer Securities, to permit Bearer Securities
to be issued in exchange for Registered Securities, to permit Bearer Securities
to be issued in exchange for Bearer Securities of other authorized 
denominations or to permit or facilitate the issuance of Securities in
uncertificated form, provided that any such action shall not adversely affect 
the interests of the Holders of Securities of any series or any related coupons
in any material respect; or

         (5)     to add to, change or eliminate any of the provisions of this
Indenture in respect of any series of Securities, provided that any such
addition, change or elimination shall (i) neither (A) apply to any Security of
any series created prior to the execution of such supplemental indenture and
entitled to the benefit of such provision, nor (B) modify the rights of the
Holder of any such Security with respect to such provision; or (ii) become
effective only when there is no Security Outstanding; or

         (6)     to secure the Securities; or

         (7)     to establish the form or terms of Securities of any series and
any related coupons as permitted by Sections 201 and 301, including the
provisions and procedures relating to Securities convertible into or
exchangeable for other securities or property of the Company; or

         (8)     to evidence and provide for the acceptance of appointment
hereunder by a successor Trustee with respect to the Securities of one or more
series and to add to or change any of the provisions of this Indenture as shall
be necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee; or

         (9)     to make provision with respect to the conversion or exchange
rights of Holders pursuant to the requirements of Article Sixteen, including
providing for the conversion or exchange of the Securities into any security or
property of the Company; or

         (10)    to cure any ambiguity, to correct or supplement any provision
herein which may be defective or inconsistent with any other provision herein,
or to make any other provisions with respect to matters or questions arising
under this Indenture which shall not be inconsistent with the provisions of
this Indenture or to make any other changes, provided that in each case, such
provisions shall not adversely affect the interests of the Holders of
Securities of any series or any related coupons in any material respect; or


                                      51

<PAGE>   59

         (11)    to close this Indenture with respect to the authentication and
delivery of additional series of Securities or to qualify, or maintain
qualification of, this Indenture under the TIA; or

         (12)    to supplement any of the provisions of this Indenture to such
extent as shall be necessary to permit or facilitate the defeasance and
discharge of any series of Securities pursuant to Sections 401, 1402 and 1403;
provided in each case that any such action shall not adversely affect the
interests of the Holders of Securities of such series and any related coupons or
any other series of Securities in any material respect.

         SECTION 902.     Supplemental Indentures with Consent of Holders.

         With the consent of the Holders of not less than a majority in
principal amount of all Outstanding Securities affected by such supplemental
indenture, by Act of said Holders delivered to the Company and the Trustee, the
Company, when authorized by or pursuant to a Board Resolution, and the Trustee
may enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities and any related coupons under this Indenture; provided,
however, that no such supplemental indenture shall, without the consent of the
Holder of each Outstanding Security affected thereby:

         (1)     change the Stated Maturity of the principal of (or premium or
Make-Whole Amount, if any, on) or any installment of principal of or interest
on, any Security; or reduce the principal amount thereof or the rate or amount
of interest thereon or any Additional Amounts payable in respect thereof, or
any premium or Make-Whole Amount payable upon the redemption thereof, or change
any obligation of the Company to pay Additional Amounts pursuant to Section
1011 (except as contemplated by Section 801(i) and permitted by Section
901(1)), or reduce the amount of the principal of an Original Issue Discount
Security or Make-Whole Amount, if any, that would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 502 or
the amount thereof provable in bankruptcy pursuant to Section 504, or adversely
affect any right of repayment at the option of the Holder of any Security, or
change any Place of Payment where, or the currency or currencies, currency unit
or units or composite currency or currencies in which, the principal of any
Security or any premium or Make-Whole Amount or any Additional Amounts payable
in respect thereof or the interest thereon is payable, or impair the right to
institute suit for the enforcement of any such payment on or after the Stated
Maturity thereof (or, in the case of redemption or repayment at the option of
the Holder, on or after the Redemption Date or the Repayment Date, as the case
may be); or

         (2)     reduce the percentage in principal amount of the Outstanding
Securities of any series, the consent of whose Holders is required for any such
supplemental indenture, or the consent of whose Holders is required for any
waiver with respect to such series (or compliance with certain provisions of
this Indenture or certain defaults hereunder and their consequences) provided
for in this Indenture, or reduce the requirements of Section 1504 for quorum or
voting; or

         (3)     modify any of the provisions of this Section, Section 513 or
Section 1012, except to increase the required percentage to effect such action
or to provide that certain other provisions of


                                      52

<PAGE>   60
this Indenture cannot be modified or waived without the consent of the Holder
of each Outstanding Security affected thereby; or make any change that
adversely affects the right to convert or exchange any Security as provided in
Article Sixteen or pursuant to Section 301 (except as permitted by Section
901(9) or decrease the conversion or exchange rate or increase the conversion
or exchange price of any such Security. 

         (4) make any change that adversely affects the right to convert or
exchange any Security as provided in Article Sixteen or pursuant to Section 301
(except as permitted by Section 901(9)) or decrease the conversion or exchange
rate or increase the conversion or exchange price of any such Security.

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

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

         SECTION 903.     Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modification thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and shall be fully protected in relying upon, an Opinion of Counsel and an
Officer's Certificate stating that the execution of such supplemental indenture
is authorized or permitted by this Indenture and that all conditions precedent
to the execution of such supplemental indenture have been complied with.  The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

         SECTION 904.     Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every
Holder of Securities theretofore or thereafter authenticated and delivered
hereunder and of any coupon appertaining thereto shall be bound thereby.

         SECTION 905.     Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

         SECTION 906.     Reference in Securities to Supplemental Indentures.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as

shall so determine, new Securities of any series so modified as to conform, in
the opinion of the Trustee and the Company, to any such supplemental indenture
may be prepared and executed by the Company and authenticated and delivered by
the Trustee in exchange for Outstanding Securities of such series.

         SECTION 907.     Notice of Supplemental Indentures.

substance of such


                                      53

supplemental indenture.

                                   COVENANTS

         SECTION 1001.    Payment of Principal, Premium or Make-Whole Amount,
                          if any, Interest and Additional Amounts.

         The Company covenants and agrees for the benefit of the Holders of
each series of Securities that it will duly and punctually pay the principal of
(and premium or Make-Whole Amount, if any) and interest on and any Additional
Amounts payable in respect of the Securities of that series in accordance with
the terms of such series of Securities, any coupons appertaining thereto and
this Indenture.  Unless otherwise specified as contemplated by Section 301 with
respect to any series of Securities, any interest due on and any Additional
Amounts payable in respect of Bearer Securities on or before Maturity, other
than Additional Amounts, if any, payable as provided in Section 1011 in respect
of principal of (or premium or Make-Whole Amount, if any, on) such a Security,
shall be payable only upon presentation and surrender of the several coupons
for such interest installments as are evidenced thereby as they severally
mature.  Unless otherwise specified with respect to Securities of any series
pursuant to Section 301, at the option of the Company, all payments of
principal may be paid by check to the registered Holder of the Registered
Security or other person entitled thereto against surrender of such Security.

         SECTION 1002.    Maintenance of Office or Agency.

   
         If Securities of a series are issuable only as Registered Securities,
the Company shall maintain in each Place of Payment for any series of Securities
an office or agency where Securities of that series may be presented or
surrendered for payment or conversion, where Securities of that series may be
surrendered for registration of transfer or exchange, where Securities of that
series may be converted or exchanged in accordance with Article Sixteen, and
where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served.  If Securities of a series are
issuable as Bearer Securities, the Company will maintain: (A) in the City of
Atlanta, Georgia or in the Borough of Manhattan, The City of New York, an office
or agency where any Registered Securities of that series may be presented or
surrendered for payment or conversion, where any Registered Securities of that
series may be surrendered for exchange, where notices and demands to or upon the
Company in respect of the Securities of that series and this Indenture may be
served and where Bearer Securities of that series and related coupons may be
presented or surrendered for payment or conversion in the circumstances
described in the following paragraph (and not otherwise); (B) subject to any
laws or regulations applicable thereto, in a Place of Payment for that series
which is located outside the United States, an office or agency where Securities
of that series and related coupons may be presented and surrendered for payment
(including payment of any Additional Amounts payable on Securities of that
series pursuant to Section 1011) or conversion; provided, however, that if the
Securities of that series are listed on the Luxembourg Stock Exchange, The
International Stock Exchange or any other stock exchange located outside the
United States and such stock exchange shall so require, the Company will
maintain a Paying Agent for the Securities of that series in Luxembourg,
London, England or any other required city located outside the United States, as
the case may be, so long as the Securities of that series are listed on such
exchange; and (C) subject to any laws or regulations applicable thereto, in each
Place of Payment for that
    


                                      54
<PAGE>   62
series located outside the United States an office or agency where any
Securities of that series may be surrendered for registration of transfer,
where Securities of that series may be surrendered for exchange and where
notices and demands to or upon the Company in respect of the Securities of that
series and this Indenture may be served.  The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of each
such office or agency. If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, except that Bearer
Securities of that series and the related coupons may be presented and
surrendered for payment (including payment of any Additional Amounts payable on
Bearer Securities of that series pursuant to Section 1011) at the offices
specified in the Security, in London, England, and the Company hereby appoints
the same as its agent to receive such respective presentations, surrenders,
notices and demands, and the Company hereby appoints the Trustee its agent to
receive all such presentations, surrenders, notices and demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium, Make-Whole Amount or interest on
or Additional Amounts in respect of Bearer Securities shall be made at any
office or agency of the Company in the United States or by check mailed to any
address in the United States or by transfer to an account maintained with a
bank located in the United States; provided, however, that, if the Securities
of a series are payable in Dollars, payment of principal of and any premium and
interest on any Bearer Security (including any Additional Amounts or Make-Whole
Amount payable on Securities of such series pursuant to Section 1011) shall be
made at the office of the Company's Paying Agent in the City of Atlanta,
Georgia or the Borough of Manhattan, The City of New York, if (but only if)
payment in Dollars of the full amount of such principal, premium, interest,
Additional Amounts or Make-Whole Amount, as the case may be, at all offices or
agencies outside the United States maintained for the purpose by the Company in
accordance with this Indenture, is illegal or effectively precluded by exchange
controls or other similar restrictions.

         The Company may from time to time designate one or more other offices
or agencies where the Securities of one or more series and related coupons, if
any, may be presented or surrendered for any or all of such purposes, and may
from time to time rescind such designations; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in accordance with the requirements
set forth above for Securities of any series for such purposes. The Company
will give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or
agency.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of the Indenture, then the Company
will maintain with respect to each such series of Securities, or as so
required, at least one exchange rate agent.

         SECTION 1003.    Money for Securities Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of any Securities and any related


                                      55

<PAGE>   63

coupons, it will, on or before each due date of the principal of (and premium or
Make-Whole Amount, if any), or interest on or Additional Amounts in respect of,
any of the Securities of that series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant
to Section 301 for the Securities of such series) sufficient to pay the
principal (and premium or Make-Whole Amount, if any) or interest or Additional
Amounts so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided, and will promptly notify the Trustee
of its action or failure so to act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, on or before each due
date of the principal of (and premium or Make-Whole Amount, if any), or
interest on or Additional Amounts in respect of, any Securities of that series,
deposit with a Paying Agent a sum (in the currency or currencies, currency unit
or units or composite currency or currencies described in the preceding
paragraph) sufficient to pay the principal (and premium or Make-Whole Amount,
if any) or interest or Additional Amounts, so becoming due, such sum to be held
in trust for the benefit of the Persons entitled to such principal, premium,
Make-Whole Amount or interest or Additional Amounts and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its
action or failure so to act.

         The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:

         (1)     hold all sums held by it for the payment of principal of (and
premium or Make-Whole Amount, if any) or interest on Securities or Additional
Amounts in trust for the benefit of the Persons entitled thereto until such
sums shall be paid to such Persons or otherwise disposed of as herein provided;

         (2)     give the Trustee written notice of any default by the Company 
(or any other obligor upon the Securities) in the making of any such payment of
principal (and premium or Make-Whole Amount, if any) or interest or Additional
Amounts; and

         (3)     at any time during the continuance of any such default upon
the written request of the Trustee, forthwith pay to the Trustee all sums so
held in trust by such Paying Agent.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held
in trust by the Company or such Paying Agent, such sums to be held by the
Trustee upon the same trusts as those upon which such sums were held by the
Company or such Paying Agent; and, upon such payment by any Paying Agent to
the Trustee, such Paying Agent shall be released from all further liability
with respect to such sums.

         Except as otherwise provided in the Securities of any series, any
money deposited with the Trustee or any Paying Agent, or then held by the
Company, in trust for the payment of the principal of (and premium or
Make-Whole Amount, if any) or interest on, or any Additional Amounts in respect
of, any Security of any series and remaining unclaimed for two years after such
principal (and premium or Make-Whole Amount, if any), interest or Additional

<PAGE>   64
Amounts has become due and payable shall be paid to the Company upon Company
Request or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment of such principal of (and
premium or Make-Whole Amount, if any) or interest on, or any Additional Amounts
in respect of, any Security, without interest thereon, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all
liability of the Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make
any such repayment, may at the expense of the Company cause to be published
once, in an Authorized Newspaper, notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

<PAGE>   65

         SECTION  1005.   Existence.

         Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect the existence,
rights (charter and statutory) and franchises of the Company and its
Subsidiaries; provided, however, that the Company shall not be required to
preserve any right or franchise if the Board of Directors shall determine that
the preservation thereof is no longer desirable in the conduct of the business
of the Company and its Subsidiaries as a whole and that the loss thereof is not
disadvantageous in any material respect to the Holders of Securities of any
series.

         SECTION 1006.    Maintenance of Properties.

         The Company will cause all of its material properties used or useful in
the conduct of its business or the business of any Subsidiary to be maintained 
and kept in good condition, repair and working order and supplied with all
necessary equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent the Company or any
Subsidiary from selling or otherwise disposing of its properties in the 
ordinary course of its business.

         SECTION 1007.    Insurance.

         The Company will, and will cause each of its Subsidiaries to, keep all
its insurable properties insured against loss or damage with commercially
reasonable amounts and types of insurance provided by insurers of recognized
responsibility.

         SECTION 1008.    Payment of Taxes and Other Claims.

         The Company will pay or discharge or cause to be paid or discharged, 
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon it or any Subsidiary or upon the
income, profits or property of the Company or any Subsidiary, and (2) all
lawful claims for labor, materials and supplies which, if unpaid, might by law
become a lien


                                      58

<PAGE>   66

upon the property of the Company or any Subsidiary; provided, however, that the
Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

         SECTION 1009.    Provision of Financial Information.

         Whether or not the Company is subject to Section 13 or 15(d) of the
Exchange Act, the Company will, to the extent permitted under the Exchange Act,
file with the Commission the annual reports, quarterly reports and other
documents which the Company would have been required to file with the
Commission pursuant to such Section 13 or 15(d) (the "Financial Statements") if
the Company were so subject, such documents to be filed with the Commission on
or prior to the respective dates (the "Required Filing Dates") by which the
Company would have been required so to file such documents if the Company were
so subject.

         The Company will also in any event (x) within 15 days of each
Required Filing Date file with the Trustee copies of annual reports, quarterly
reports and other documents which the Company would have been required to file
with the Commission pursuant to Section 13 or 15(d) of the Exchange Act if the
Company were subject to such Sections, and (y) if filing such documents by the
Company with the Commission is not permitted under the Exchange Act, promptly
upon written request and payment of the reasonable cost of duplication and
delivery, supply copies of such documents to any prospective Holder.

         SECTION 1010.    Statement as to Compliance.

         The Company will deliver to the Trustee within 120 days after the end
of each fiscal year, a brief certificate from the principal executive officer,
principal financial officer or principal accounting officer as to his or her
knowledge of the Company's compliance with all conditions and covenants under
this Indenture and, in the event of any noncompliance, specifying such
noncompliance and the nature and status thereof. For purposes of this Section
1010, such compliance shall be determined without regard to any period of grace
or requirement of notice under this Indenture.

         SECTION 1011.    Additional Amounts.

         If any Securities of a series provide for the payment of Additional
Amounts, the Company will pay to the Holder of any Security of such series or
any coupon appertaining thereto Additional Amounts as may be specified as
contemplated by Section 301. Whenever in this Indenture there is mentioned, in
any context except in the case of Section 502(1), the payment of the principal
of or any premium, Make-Whole Amount or interest on, or in respect of, any
Security of any series or payment of any related coupon or the net proceeds
received on the sale or exchange of any Security of any series, such mention
shall be deemed to include mention of the payment of Additional Amounts
provided by the terms of such series established pursuant to Section 301 to the
extent that, in such context, Additional Amounts are, were or would be payable
in respect thereof pursuant to such terms and express mention of the payment of
Additional Amounts (if applicable) in any provisions hereof shall not be
construed as excluding Additional Amounts in


                                      59


<PAGE>   67

those provisions hereof where such express mention is not made.

   
         Except as otherwise specified as contemplated by Section 301, if the
Securities of a series provide for the payment of Additional Amounts, at least
10 days prior to the first Interest Payment Date with respect to that series of
Securities (or if the Securities of that series will not bear interest prior to
Maturity, the first day on which a payment of principal and any premium is
made), and at least 10 days prior to each date of payment of principal and any
premium or Make-Whole Amount or interest if there has been any change with
respect to the matters set forth in the below-mentioned Officers' Certificate,
the Company will furnish the Trustee and the Company's principal Paying Agent
or Paying Agents, if other than the Trustee, with an Officers' Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of and any premium or interest on the Securities of that
series shall be made to Holders of Securities of that series or any related
coupons who are not United States persons without withholding for or on account
of any tax, assessment or other governmental charge described in the Securities
of or within the series. If any such withholding shall be required, then such
Officers' Certificate shall specify by country the amount, if any, required to
be withheld on such payments to such Holders of Securities of that series or
related coupons and the Company will pay to the Trustee or such Paying Agent
the Additional Amounts, if any, required by the terms of such Securities. In
the event that the Trustee or any Paying Agent, as the case may be, shall not
so receive the above mentioned certificate, then the Trustee or such Paying
Agent shall be entitled (i) to assume that no such withholding or deduction is
required with respect to any payment of principal or interest with respect to
any Securities of a series or related coupons until it shall have received a
certificate advising otherwise and (ii) to make all payments of principal and
interest with respect to the Securities of a series or related coupons without
withholding or deductions until otherwise advised. The Company covenants to
indemnify the Trustee and any Paying Agent and their respective officers,
directors, employees and agents for, and to hold them harmless against, any
loss, liability or expense (including but not limited to legal fees and
expenses) reasonably incurred without gross negligence or bad faith on their
part arising out of or in connection with actions taken or omitted by any of
them in reliance on any Officers' Certificate furnished pursuant to this Section
or in reliance on the Company's not furnishing such an Officers' Certificate.
    

         SECTION 1012.    Waiver of Certain Covenants.

   
         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Sections 1005 to 1009, inclusive, and
with any other term, provision or condition with respect to the Securities of
any series specified in accordance with Section 301 (except any such term,
provision or condition which could not be amended without the consent of all
Holders of Securities of such series pursuant to Section 902), if before or
after the time for such compliance the Holders of at least a majority in
principal amount of all outstanding Securities of such series, by Act of such
Holders, either waive such compliance in such instance or generally waive
compliance with such covenant or condition, but no such waiver shall extend to
or affect such covenant or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Company
and the duties of the Trustee in respect of any such term, provision or
condition shall remain in full force and effect.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

         SECTION 1101.    Applicability of Article.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for Securities of any
series) in accordance with this Article.

         SECTION 1102.    Election to Redeem; Notice to Trustee.

   
         The election of the Company to redeem any Securities shall be
evidenced by or pursuant to a Board Resolution.  In case of any redemption at
the election of the Company of less than all of the Securities of any series,
the Company shall, at least 45 days prior to the giving of the notice of
redemption in Section 1104 (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee, in writing,  of such Redemption Date and of the
principal amount of Securities of such series to be redeemed and the Redemption
Price of such Securities and any accrued interest and Additional Amounts payable
with respect thereto, if any, on the Redemption Date. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
and Opinion of Counsel evidencing compliance with such restriction.
    

         SECTION 1103.    Selection by Trustee of Securities to Be Redeemed.

         If less than all the Securities of any series issued on the same day
with the same terms are to be redeemed, the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date
by the Trustee, from the Outstanding Securities of such series issued on such
date with the same terms not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to the minimum authorized
denomination for Securities of that series or any integral multiple thereof) of
the principal amount of Securities of such series of a denomination larger than
the minimum authorized denomination for Securities of that series.

         If any Security selected for partial redemption is converted in part
before termination of the conversion or exchange right with respect to the
portion of the Security so selected, the converted or exchange portion of such
Security shall be deemed (so far as may be) to be the portion selected for
redemption. Securities which have been converted or exchanged during a selection
of Securities to be deemed shall be treated by the Trustee as Outstanding for
the purposes of such selection. In any case where more than one Security is
registered in the same name, the Trustee in its discretion may treat the
aggregate principal amount so registered as if it were represented by one
Security.

         The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) 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.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

         SECTION 1104.    Notice of Redemption.

         Notice of redemption shall be given in the manner provided in Section
106, not less than 30 days nor more than 60 days prior to the Redemption Date,
unless a shorter period is specified by the terms of such series established
pursuant to Section 301, to each Holder of Securities to be redeemed, but
failure to give such notice in the manner herein provided to the Holder of any
Security designated for redemption as a whole or in part, or any defect in the
notice to any such Holder, shall not affect the validity of the proceedings for
the redemption of any other such Security or portion thereof.

         Any notice that is mailed to the Holders of Registered


                                      61
<PAGE>   69

Securities in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not the Holder receives the notice.

         All notices of redemption shall state:

         (1)     the Redemption Date;

         (2)     the Redemption Price, accrued interest to the Redemption Date
payable as provided in Section 1106, if any, and Additional Amounts, if any;

         (3)     if less than all Outstanding Securities of any series are to
be redeemed, the identification (and, in the case of partial redemption, the
principal amount) of the particular Security or Securities to be redeemed;

         (4)     in case any Security is to be redeemed in part only, that on
and after the Redemption Date, upon surrender of such Security, the holder will
receive, without a charge, a new Security or Securities of authorized
denominations for the principal amount thereof remaining unredeemed;

         (5)     that on the Redemption Date the Redemption Price and accrued
interest to the Redemption Date payable as provided in Section 1106, if any,
will become due and payable upon each such Security, or the portion thereof, to
be redeemed and, if applicable, that interest thereon shall cease to accrue on
and after said date;

         (6)     the Place or Places of Payment where such Securities, together
in the case of Bearer Securities with all coupons appertaining thereto, if any,
maturing after the Redemption Date, are to be surrendered for payment of the
Redemption Price and accrued interest, if any, or for conversion or exchange;

         (7)     that the redemption is for a sinking fund, if such is the case;

         (8)     that, unless otherwise specified in such notice, Bearer
Securities of any series, if any, surrendered for redemption must be
accompanied by all coupons maturing subsequent to the date fixed for redemption
or the amount of any such missing coupon or coupons will be deducted from the
Redemption Price, unless security or indemnity satisfactory to the Company, the
Trustee for such series and any Paying Agent is furnished;

         (9)     if Bearer Securities of any series are to be redeemed and any
Registered Securities of such series are not to be redeemed, and if such Bearer
Securities may be exchanged for Registered Securities not subject to the
redemption on this Redemption Date pursuant to Section 305 or otherwise, the
last date, as determined by the Company, on which such exchanges may be made;

         (10)    the CUSIP number of such Security, if any, provided that
neither the Company nor the Trustee shall have any responsibility for any such
CUSIP number; and

   
         (11)    if applicable, that a Holder of Securities who desires to
convert or exchange Securities to be redeemed must satisfy the requirements for
conversion or exchange contained in such Securities, the then existing
conversion or exchange price or rate and the date and time when the option to
convert or exchange shall expire and the place or places where such Securities
may be surrendered for conversion or exchange; and

         (12)    such other information as the Trustee reasonably deems
appropriate.
    

         Notice of redemption of Securities to be redeemed shall be given by
the Company or, at the Company's written request, by the Trustee in


                                      62

<PAGE>   70

the name and at the expense of the Company.

         SECTION 1105. Deposit of Redemption Price.

         On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, which it may not do in the case of a sinking fund payment under Article
Twelve, segregate and hold in trust as provided in Section 1003) an amount of
money in the currency or currencies, currency unit or units or composite
currency or currencies in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of
such series) sufficient to pay on the Redemption Date the Redemption Price of,
and (except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities or portions thereof which are to be redeemed on
that date.

         SECTION 1106. Securities Payable on Redemption Date.

   
         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified in the currency or currencies, currency unit
or units or composite currency or currencies in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 301 for
the Securities of such series) (together with accrued interest and Additional
Amounts payable with respect thereto, if any, on the Redemption Date), and from
and after such date (unless the Company shall default in the payment of the
Redemption Price and accrued interest and Additional Amounts, if any) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
redeemed, except to the extent provided below, shall be void. Upon surrender of
any such Security for redemption in accordance with said notice, together with
all coupons, if any, appertaining thereto maturing after the Redemption Date,
such Security shall be paid by the Company at the Redemption Price, together
with accrued interest and Additional Amounts payable with respect thereto, if
any, on the Redemption Date; provided, however, that installments of interest on
Bearer Securities whose Stated Maturity is on or prior to the Redemption Date
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
as contemplated by Section 301, only upon presentation and surrender of coupons
for such interest; and provided further that except as otherwise provided with
respect to Securities convertible or exchangeable into other securities or
property (including securities of other issuers, provided that such securities
are registered under Section 12 of the Exchange Act and such issuer is then
eligible to use Form S-3 (or any successor form) for a primary offering of its
securities) of the Company, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such securities, or one or more Predecessor securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.
    

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such
missing coupon or coupons may be waived by the Company and the Trustee if there
be furnished to them such security or indemnity as they may require to save
each of them and any Paying Agent harmless. If thereafter the Holder of such
Security shall surrender to the Trustee or any Paying Agent any such missing
coupon in respect of which a deduction shall have been made from the Redemption
Price, such Holder shall be entitled to receive the amount so deducted;
provided, however, that interest represented by coupons shall be payable only
at an office or agency located outside the United States (except as otherwise
provided in


                                      63

<PAGE>   71

Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons. If any Security called
for redemption shall not be so paid upon surrender thereof for redemption, the
principal, (and premium or Make-Whole Amount, if any) shall, until paid, bear
interest from the Redemption Date at the rate borne by the Security.

         SECTION 1107.    Securities Redeemed in Part.

         Any Security which is to be redeemed only in part (pursuant to the
provisions of this Article or of Article Twelve) shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing) and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge
a new Security or Securities of the same series, of any authorized denomination
as requested by such Holder in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so
surrendered.

                               ARTICLE TWELVE

                                SINKING FUNDS

         SECTION 1201.    Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series 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 such Securities of any series is herein referred to as an
"optional sinking fund payment." If provided for by the terms of any Securities
of any series, the cash amount of any mandatory sinking fund payment may be
subject to reduction as provided in Section 1202. Each sinking fund payment
shall be applied to the redemption of Securities of any series as provided for
by the terms of Securities of such series.

         SECTION 1202.    Satisfaction of Sinking Fund Payments with Securities.

         The Company may, in satisfaction of all or any part of any mandatory
sinking fund payment with respect to the Securities of a series, (1) deliver
Outstanding Securities of such series (other than any previously called for
redemption) together in the case of any Bearer Securities of such series with
all unmatured coupons appertaining thereto and (2) apply as a credit Securities
of such series which have been redeemed either at the election of the Company
pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, as provided for by the terms of such Securities, or which have
otherwise been acquired by the Company; provided that such Securities so
delivered or applied as a credit have not been previously so credited.  Such
Securities shall be received and credited for such purpose by the Trustee at
the applicable Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such mandatory sinking
fund payment shall be reduced accordingly.

<PAGE>   72


         SECTION 1203.    Redemption of Securities for Sinking Fund.

   
         Not less than 60 days prior to each sinking fund payment date for
Securities of any series, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash in the currency or
currencies, currency unit or units or composite currency or currencies in which
the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) and the portion
thereof, if any, which is to be satisfied by delivering and crediting Securities
of that series pursuant to Section 1202, and the amount of optional sinking fund
payments, if any, to be added in cash to the next ensuing mandatory sinking fund
payment, and will also deliver to the Trustee any Securities to be so delivered
and credited. If such Officers' Certificate shall specify an optional amount to
be added in cash to the next ensuing mandatory sinking fund payment, the Company
shall thereupon be obligated to pay the amount therein specified. Not less than
30 days before each such sinking fund payment date the Trustee shall select the
Securities to be redeemed upon such sinking fund payment date in the manner
specified in Section 1103 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Company in the manner provided in
Section 1104. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
1106 and 1107.
    

                              ARTICLE THIRTEEN

                     REPAYMENT AT THE OPTION OF HOLDERS

         SECTION 1301.    Applicability of Article.

         Repayment of Securities of any series before their Stated Maturity at
the option of Holders thereof shall be made in accordance with the terms of
such Securities, if any, and (except as otherwise specified by the terms of
such series established pursuant to Section 301) in accordance with this
Article.

         SECTION 1302.    Repayment of Securities.

   
         Securities of any series subject to repayment in whole or in part at
the option of the Holders thereof will, unless otherwise provided in the terms
of such Securities, be repaid at a price equal to the principal amount thereon,
together with interest, if any, thereof accrued to the Repayment Date specified
in or pursuant to the terms of such Securities and Additional Amounts, if any,
payable thereon. The Company covenants that on or before the Repayment Date it
will deposit with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003) an amount of money in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) sufficient to pay the principal (or, if so provided
by the terms of the Securities of any series, a percentage of the principal) of,
and (except if the Repayment Date shall be an Interest Payment Date) accrued
interest on, all the Securities or portions thereof, as the case may be, to be
repaid on such date and Additional Amounts, if any, payable thereon.
    

         SECTION 1303.    Exercise of Option.

         Securities of any series subject to repayment at the option of the
Holders thereof will contain an "Option to Elect Repayment" form on the
reverse of such Securities. In order for any Security


                                      65

<PAGE>   73


   
to be repaid at the option of the Holder, the Trustee must receive at the Place
of Payment therefor specified in the terms of such Security (or at such other
place or places of which the Company shall from time to time notify the Holders
of such Securities and the Trustee) not earlier than 60 days nor later than 30
days prior to the Repayment Date (1) the Security so providing for such
repayment together with the "Option to Elect Repayment" form on the reverse
thereof duly completed by the Holder (or by the Holder's attorney duly
authorized in writing) or (2) a telegram, telex, facsimile transmission or a
letter from a member of a national securities exchange, or the National
Association of Securities Dealers, Inc. ("NASD"), or a commercial bank or trust
company in the United States setting forth the name of the Holder of the
Security, the principal amount of the Security, the principal amount of the
Security to be repaid, the CUSIP number, if any, or a description of the tenor
and terms of the Security, a statement that the option to elect repayment is
being exercised thereby and a guarantee that the Security to be repaid, together
with the duly completed form entitled "Option to Elect Repayment" on the reverse
of the Security, will be received by the Trustee not later than the fifth
Business Day after the date of such telegram, telex, facsimile transmission or
letter; provided, however, that such telegram, telex, facsimile transmission or
letter shall only be effective if such Security and form duly completed are
received by the Trustee by such fifth Business Day. If less than the entire
principal amount of such Security is to be repaid in accordance with the terms
of such Security, the principal amount of such Security to be repaid, in
increments of the minimum denomination for Securities of such series, and the
denomination or denominations of the Security or Securities to be issued to the
Holder for the portion of the principal amount of such Security surrendered that
is not to be repaid, must be specified. The principal amount of any Security
providing for repayment at the option of the Holder thereof may not be repaid in
part if, following such repayment, the unpaid principal amount of such Security
would be less than the minimum authorized denomination of Securities of or
within the series of which such Security to be repaid is a part. Except as
otherwise may be provided by the terms of any Security providing for repayment
at the option of the Holder thereof, exercise of the repayment option by the
Holder shall be irrevocable unless waived by the Company.
    

         SECTION 1304.    When Securities Presented for Repayment
                          Become Due and Payable.

         If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void. Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the principal amount of such security so to be repaid shall be paid by
the Company, together with accrued interest, if any, to the Repayment Date;
provided, however, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and provided further


                                      66

<PAGE>   74


that, in the case of Registered Securities, installments of interest, if any,
whose Stated Maturity is on or prior to the Repayment Date shall be payable
(but without interest thereon, unless the Company shall default in the payment
thereof) to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 307.

         If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by
the Company and the Trustee if there be furnished to them such security or
indemnity as they may require to save each of them and any Paying Agent
harmless. If thereafter the Holder of such Security shall surrender to the
Trustee or any Paying Agent any such missing coupon in respect of which a
deduction shall have been made as provided in the preceding sentence, such
Holder shall be entitled to receive the amount so deducted; provided, however,
that interest represented by coupons shall be payable only at an office or
agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons. If the principal amount
of any Security surrendered for repayment shall not be so repaid upon surrender
thereof, such principal amount (together with interest, if any, thereon accrued
to such Repayment Date) shall, until paid, bear interest from the Repayment
Date at the rate of interest or Yield to Maturity (in the case of Original
Issue Discount Securities) set forth in such Security.

         SECTION 1305.    Securities Repaid in Part.

         Upon surrender of any Registered Security which is to be repaid in
part only, the Company shall execute and the Trustee shall authenticate and
deliver to the Holder of such Security, without service charge and at the
expense of the Company, a new Registered Security or Securities of the same
series, of any authorized denomination specified by the Holder, in an aggregate
principal amount equal to and in exchange for the portion of the principal of
such Security so surrendered which is not to be repaid.

                     DEFEASANCE AND COVENANT DEFEASANCE

         SECTION 1401.     Applicability of Article; Company's Option to
                           Effect Defeasance or Covenant Defeasance.

         If, pursuant to Section 301, provision is made for either or both of
(a) defeasance of the Securities of or within a series under Section 1402 or
(b) covenant defeasance of the Securities of or within a series under Section
1403 to be applicable to the Securities of any series, then the provisions of
such Section or Sections, as the case may be, together with the other
provisions of this Article (with such modifications thereto as may be specified
pursuant to Section 301 with respect to any Securities), shall be applicable to
such Securities and any coupons appertaining thereto, and the Company may at
its option by Board Resolution at any time, with respect to such Securities and
any coupons appertaining thereto, elect to defease such Outstanding Securities
and any coupons appertaining thereto pursuant to Section 1402 (if applicable)
or Section 1403 (if applicable) upon compliance with the conditions set forth
below in this Article.


                                      67

<PAGE>   75


         SECTION 1402.    Defeasance and Discharge.

   
         Upon the Company's exercise of the above option applicable to this
Section with respect to any Securities of or within a series, the Company shall
be deemed to have been discharged from its obligations with respect to such
Outstanding Securities and any coupons appertaining thereto on the date the
conditions set forth in Section 1404 are satisfied (hereinafter, "defeasance").
For this purpose, such defeasance means that the Company shall be deemed to
have paid and discharged the entire indebtedness represented by such
Outstanding Securities and any coupons appertaining thereto, which shall
thereafter be deemed to be "Outstanding" only for the purposes of Section 1405
and the other Sections of this Indenture referred to in clauses (A) and (B)
below, and to have satisfied all of its other obligations under such Securities
and any coupons appertaining thereto and this Indenture insofar as such
Securities and any coupons appertaining thereto are concerned (and the Trustee,
at the expense of the Company, shall execute proper instruments acknowledging
the same), except for the following which shall survive until otherwise
terminated or discharged hereunder: (A) the rights of Holders of such
Outstanding Securities and any coupons appertaining thereto to receive, solely
from the trust fund described in Section 1404 and as more fully set forth in
such Section, payments in respect of the principal of (and premium or
Make-Whole Amount, if any) and interest, if any, on such Securities and any
coupons appertaining thereto when such payments are due, (B) the Company's
obligations with respect to such Securities under Sections 305, 306, 1002 and
1003 and with respect to the payment of Additional Amounts, if any, on such
Securities as contemplated by Section 1011, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder including but not limited to
Section 606 hereof and (D) this Article.  Subject to compliance with this
Article Fourteen, the Company may exercise its option under this Section
notwithstanding the prior exercise of its option under Section 1403 with respect
to such Securities and any coupons appertaining thereto.
    

         SECTION 1403.    Covenant Defeasance.

        Upon the Company's exercise of the above option applicable to this
Section with respect to any Securities of or within a series, the Company shall
be released from its obligations under Sections 1005 to 1009, inclusive, and,
if specified pursuant to Section 301, its obligations under any other covenant,
with respect to such Outstanding Securities and any coupons appertaining
thereto on and after the date the conditions set forth in Section 1404 are
satisfied (hereinafter, "covenant defeasance"), and such Securities and any
coupons appertaining thereto shall thereafter be deemed to be not "Outstanding"
for the purposes of any direction, waiver, consent or declaration or Act of
Holders (and the consequences of any thereof) in connection with Sections 1005
to 1009, inclusive, or such other covenant, but shall continue to be deemed
"Outstanding" for all other purposes hereunder.  For this purpose, such
covenant defeasance means that, with respect to such Outstanding Securities and
any coupons appertaining thereto, the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such Section or such other covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or such other
covenant or by reason of reference in any such Section or such other covenant 
to any other provision herein or in any other document and such omission to 
comply shall not constitute a default or an Event of Default under Section 
501(4) or 501(8) or otherwise, as the case may be, but, except as specified 
above, the remainder of this Indenture and such Securities and any coupons 
appertaining thereto shall be unaffected thereby.

         SECTION 1404.    Conditions to Defeasance or Covenant Defeasance.

         The following shall be the conditions to application of Section 1402 or
Section 1403 to any Outstanding Securities of or within a series and any
coupons appertaining thereto:

   
         (a)     The Company shall irrevocably have deposited or caused to be
deposited with the Trustee as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Securities and any coupons appertaining
thereto, (1) an amount in such currency, currencies or currency unit in which
such Securities and any coupons appertaining thereto are then specified as
payable at Stated Maturity, or (2) Government Obligations applicable to such
Securities and coupons appertaining thereto (determined on the basis of the
currency, currencies or currency unit in which such Securities and coupons
appertaining thereto are then specified as payable at Stated Maturity) which
through the scheduled payment of principal and interest in respect thereof in
accordance with their terms will provide, not later than one day before the due
date of any payment of principal of (and premium or Make-Whole Amount, if any)
and interest and Additional Amounts, if any, on such Securities and any coupons
appertaining thereto, money in an amount, or (3) a combination thereof in an
amount, sufficient, without consideration of any reinvestment of such principal
and interest, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, to pay and discharge, and which shall be applied by the Trustee to pay
and discharge, (i) the principal of (and premium or Make-Whole Amount, if any)
and interest, if any, on such Outstanding Securities and any coupons
appertaining thereto on the Stated Maturity of such principal or installment of
principal or interest and (ii) any mandatory sinking fund payments or analogous
payments applicable to such Outstanding Securities and any coupons appertaining
thereto on the day on which such payments are due and payable in accordance with
the terms of this Indenture and of such Securities and any coupons appertaining
thereto; provided, that the Trustee shall have been irrevocably instructed to
apply such money or the proceeds of such Government Obligations to said payments
with respect to such Securities.  Before such a deposit, the Company may give to
the Trustee, in accordance with Section 1102 hereof, a notice of its election to
redeem all or any portion of such Outstanding Securities at a future date in
accordance with the terms of the Securities of such series and Article Eleven
hereof, which notice shall be irrevocable.  Such irrevocable redemption notice,
if given, shall be given effect in applying the foregoing.
    

         (b)     Such defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a default under, this Indenture or any
other material agreement or instrument to which the Company is a party or by
which it is bound (and shall not cause the Trustee to have a conflicting
interest pursuant to Section 310(b) of the TIA with respect to any Security of
the Company).

         (c)     No Event of Default or event which with notice or lapse of
time or both would become an Event of Default with respect to such Securities
and any coupons appertaining thereto shall have occurred and be continuing on
the date of such deposit or, insofar as Sections 501(6) and 501(7) are
concerned, at any time during the period ending on the 91st day after the date
of such deposit (it being understood that this condition shall not be deemed
satisfied


                                      69

<PAGE>   77

until the expiration of such period).

         (d)     In the case of an election under Section 1402, the Company
shall have delivered to the Trustee an Opinion of Counsel stating that (i) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since the date of execution of this Indenture, there
has been a change in the applicable Federal income tax law, in either case to
the effect that, and based thereon such opinion shall confirm that, the Holders
of such Outstanding Securities and any coupons appertaining thereto will not
recognize income, gain or loss for Federal income tax purposes as a result of
such defeasance and will be subject to Federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such
defeasance had not occurred.

         (e)     In the case of an election under Section 1403, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that
the Holders of such Outstanding Securities and any coupons appertaining thereto
will not recognize income, gain or loss for Federal income tax purposes as a
result of such covenant defeasance and will be subject to Federal income tax on
the same amounts, in the same manner and at the same times as would have been
the case if such covenant defeasance had not occurred.

         (f)     The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion  of Counsel, each stating that all conditions
precedent to the defeasance under Section 1402 or the covenant defeasance under
Section 1403 (as the case may be) have been complied with and an Opinion of
Counsel to the effect that either (i) as a result of a deposit pursuant to
subsection (a) above and the related exercise of the Company's option under
Section 1402 or Section 1403 (as the case may be) registration is not required
under the Investment Company Act of 1940, as amended, by the Company, with
respect to the trust funds representing such deposit or by the Trustee for such
trust funds or (ii) all necessary registrations under said Act have been
effected.

         (g)     After the 91st day following the deposit, the trust funds will
not be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally.

         (h)     Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed
on the Company in connection therewith pursuant to Section 301.

         SECTION 1405.    Deposited Money and Government Obligations to Be Held
                          in Trust; Other Miscellaneous Provisions.

         Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations (or other property as may be provided pursuant
to Section 301) (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 1405, the
"Trustee") pursuant to Section 1404 in respect of any Outstanding Securities of
any series and any coupons appertaining thereto shall be held in trust and
applied by the Trustee, in accordance with the provisions of such Securities
and any coupons appertaining thereto and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities
and any coupons appertaining thereto of all sums due and to become due


                                      70

<PAGE>   78

thereon in respect of principal (and premium or Make-Whole Amount, if any) and
interest and Additional Amounts, if any, but such money need not be segregated
from other funds except to the extent required by law.

   
         Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Section 1404(a) has been made in respect of such
Security, or (b) a Conversion Event occurs in respect of the currency or
currency unit in which the deposit pursuant to Section 1404(a) has been made,
the indebtedness represented by such Security and any coupons appertaining
thereto shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium or Make-Whole
Amount, if any), and interest, if any, on such Security as the same becomes due
and Additional Amounts, if any, out of the proceeds yielded by converting (from
time to time as specified below in the case of any such election) the amount or
other property deposited in respect of such Security into the currency or
currency unit in which such Security becomes payable as a result of such
election or Conversion Event based on the applicable market exchange rate for
such currency or currency unit in effect on the second Business Day prior to
each payment date, except, with respect to a Conversion Event, for such currency
or currency unit in effect (as nearly as feasible) at the time of the Conversion
Event.
    

         The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the Government Obligations
deposited pursuant to Section 1404 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of such Outstanding Securities and any coupons
appertaining thereto.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or Government Obligations (or other property and any proceeds therefrom)
held by it as provided in Section 1404 which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount
thereof which would then be required to be deposited to effect a defeasance or
covenant defeasance, as applicable, in accordance with this Article.

                               ARTICLE FIFTEEN

                      MEETINGS OF HOLDERS OF SECURITIES

         SECTION 1501.    Purposes for Which Meetings May Be Called.

<PAGE>   80


or adjourned meeting duly reconvened at which a quorum is present as
aforesaid may be adopted by the affirmative vote of the Holders of a majority
in principal amount of the Outstanding Securities of that series; provided,
however, that, except as limited by the proviso to Section 902, any resolution
with respect to any request, demand, authorization, direction, notice, consent,
waiver or other action which this Indenture expressly provides may be made,
given or taken by the Holders of a specified percentage, which is less than a
majority, in principal amount of the Outstanding Securities of a series may be
adopted at a meeting or an adjourned meeting duly reconvened and at which a
quorum is present as aforesaid by the affirmative vote of the Holders of such
specified percentage in principal amount of the Outstanding Securities of that
series.

         Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the related
coupons, whether or not present or represented at the meeting.

         Notwithstanding the foregoing provisions of this Section 1504, if any

respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made,
given or taken by the Holders of a specified percentage in principal amount of
all Outstanding Securities affected thereby, or of the Holders of such series
and one or more additional series:

                 and

         (ii)    the principal amount of the Outstanding Securities of such
                 series that vote in favor of such request, demand,
                 authorization, direction, notice, consent, waiver or other
                 action shall be taken into account in determining whether such
                 request, demand, authorization, direction, notice, consent,
                 waiver or other action has been made, given or taken under
                 this Indenture.

         SECTION 1505.    Determination of Voting Rights; Conduct and
                          Adjournment of Meetings.

         (a)     Notwithstanding any provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting
of Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to
the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate.  Except as otherwise permitted or required by any such
regulations, the holding of Securities shall be proved in the manner specified
in Section 104 and the appointment of any proxy shall be proved in the manner
specified in Section 104 or by having the signature of the Person executing the
proxy witnessed or guaranteed by any trust company, bank or banker authorized
by Section 104 to certify to the holding of Bearer Securities.  Such
regulations may provide that written instruments appointing proxies, regular on
their face, may be presumed valid and genuine without the proof specified in
Section 104 or other proof.

         (b)     The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1502(b), in
which case the Company or the Holders of


                                      73

<PAGE>   81

Securities of or within the series calling the meeting, as the case
may be, shall in like manner appoint a temporary chairman.  A permanent
chairman and a permanent secretary of the meeting shall be elected by vote of
the Persons entitled to vote a majority in principal amount of the Outstanding
Securities of such series represented at the meeting.

         (c)     At any meeting each Holder of a Security of such series or
proxy shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding.  The chairman of the meeting shall have no right to
vote, except as a Holder of a Security of such series or proxy.

         (d)     Any meeting of Holders of Securities of any series duly called
pursuant to Section 1502 at which a quorum is present may be adjourned from
time to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting, and the
meeting may be held as so adjourned without further notice.

         SECTION 1506.    Counting Votes and Recording Action of Meetings.

         The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be 
subscribed the signatures of the Holders of Securities of such series or of 
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them.  The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting.  A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the fact, setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1502 and, if
applicable, Section 1504.  Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting.  Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

         SECTION 1507.    Evidence of Action Taken by Holders.

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by a specified
percentage in principal amount of the Holders of any or all series may be
embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such specified percentage of Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee.  Proof of execution of any instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Article Six) conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Article.

         SECTION 1508.    Proof of Execution of Instruments.

         Subject to Article Six, the execution of any instrument by a Holder or
his agent or proxy may be proved in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee or in such manner as shall be
satisfactory to the Trustee.


                                ARTICLE SIXTEEN
                              
CONVERSION OR EXCHANGE OF SECURITIES

         SECTION 1601.  Applicability of Article.

         The provisions of this Article shall be applicable to the Securities of
any series which are convertible or exchangeable for other securities or
property (including securities of other issuers, provided that such securities
are registered under Section 12 of the Exchange Act and such issuer is then
eligible to use Form S-3 (or any successor form) for a primary offering of its
securities) of the Company, except as otherwise specified as contemplated by
Section 301 for the Securities of such series.

         SECTION 1602.  Election to Exchange; Notice to Trustee and Holders.

         The election of the Company to exchange any Securities shall be
evidenced by a Board Resolution or in another manner specified as contemplated
by Section 301 for such Securities. On or prior to the seventh Business Day
prior to Maturity of the Securities, the Company shall provide written notice to
the Holders of record of the Securities and to the Trustee and will publish a
notice in an Authorized Newspaper stating whether the Company has made such
election.

         SECTION 1603.  No Fractional Shares.

         No fractional shares or fractional securities shall be delivered upon
exchanges of Securities of any series. If more than one Security shall be
surrendered for exchange at one time by the same Holder, the number of full
shares or units which shall be delivered upon exchange shall be computed on the
basis of the aggregate principal amount of the Securities (or specified portions
thereof to the extent permitted hereby) so surrendered. If, except for the
provisions of this Section 1603, any Holder of a Security or Securities would be
entitled to a fractional share or unit of a security upon the exchange of such
Security or Securities, or specified portions thereof, the Company shall pay to
such Holder an amount in cash equal to the current market value of such
fractional share computed on the basis of the Closing Price of such security on
the date preceding the date on which the conversion or exchange shall be
effected in accordance with Section 1610. The "Closing Price" of any security on
any date of determination means, (i) if such security is listed or admitted to
unlisted trading privileges on a national securities exchange, the last reported
sales price on the composite tape on such exchange, or (ii) if such security is
not at the time so listed or admitted to unlisted trading privileges on a
national securities exchange, the average of the bid and asked prices of such
security in the over-the-counter market, as reported by Nasdaq or the National
Quotation Bureau, Incorporated or similar organization if neither Nasdaq nor the
National Quotation Bureau, Incorporated is no longer reporting such information,
or if not so available, the market price as determined by a nationally
recognized investment banking firm retained for this purpose by the Company.

         SECTION 1604.  Adjustment of Exchange Rate.

         The exchange rate of Securities of any series that is exchangeable for
other securities or property (including securities of other issuers, provided
that such securities are registered under Section 12 of the Exchange Act and
such issuer is then eligible to use Form S-3 (or any successor form) for a
primary offering of its securities) shall be adjusted for any stock dividends,
stock splits, reclassification, combinations or similar transactions or any
consolidation, merger or other reorganization event in accordance with the terms
of the supplemental indenture or Board Resolution setting forth the terms of the
Securities of such series.

         Whenever the exchange rate is adjusted, the Company shall compute the
adjusted exchange rate in accordance with terms of the applicable Board
Resolution or supplemental indenture and shall prepare an Officers' Certificate
setting forth the adjusted exchange rate and showing in reasonable detail the
facts upon which such adjustment is based, and such certificate shall forthwith
be filed at each office or agency maintained for the purpose of exchange of
Securities pursuant to Section 1002 and, if different, with the Trustee. The
Company shall forthwith cause a notice setting forth the adjusted exchange rate
to be mailed, first class postage prepaid, to each Holder of Securities of such
series at its address appearing on the Security Register and to any exchange
agent other than the Trustee.

         SECTION 1605.  Payment of Certain Taxes Upon Exchange.

         The Company will pay any and all taxes that may be payable in respect
of the transfer and delivery of shares of other securities or property
(including securities of other issuers, provided that such securities are
registered under Section 12 of the Exchange Act and such issuer is then eligible
to use Form S-3 (or any successor form) for a primary offering of its
securities) of the Company on exchange of Securities pursuant hereto. The
Company shall not, however, be required to pay any tax which may be payable in
respect of any transfer involved in the delivery of shares of securities in a
name other than that of the Holder of the Security or Securities to be
exchanged, and no such transfer or delivery shall be made unless and until the
person requesting such transfer has paid to the Company the amount of any such
tax, or has established, to the satisfaction of the Company, that such tax has
been paid.

         SECTION 1606.  Shares Free and Clear.

         The Company hereby warrants that upon exchange of Securities of any
series, the Holder of a Security shall receive all rights held by the Company in
such security for which such Security is at such time exchangeable under this
Article Sixteen, free and clear of any and all liens, claims, charges and
encumbrances other than any liens, claims, charges and encumbrances which may
have been placed on any such security by the prior owner thereof, prior to the
time such security was acquired by the Company. Except as provided in Section
1604, the Company will pay all taxes and charges with respect to the delivery of
such security delivered in exchange for Securities hereunder.

         SECTION 1607.  Cancellation of Security.

         Upon receipt by the Trustee of Securities of any series delivered to it
for exchange under this Article Sixteen, the Trustee shall cancel and dispose of
the same as provided in Section 309.

         SECTION 1608.  Duties of Trustee Regarding Exchange.

         Neither the Trustee nor any exchange agent shall at any time be under
any duty or responsibility to any Holder of Securities of any series that is
exchangeable into other securities or property (including securities of other
issuers, provided that such securities are registered under Section 12 of the
Exchange Act and such issuer is then eligible to use Form S-3 (or any successor
form) for a primary offering of its securities) of the Company to determine
whether any facts exist which may require any adjustment of the exchange rate,
or with respect to the nature or extent of any such adjustment when made, or
with respect to the method employed, whether herein or in any supplemental
indenture, any resolutions of the Board of Directors or written instrument
executed by one or more officers of the Company provided to be employed in
making the same. Neither the Trustee nor any exchange agent shall be accountable
with respect to the validity or value (or the kind or amount) of any securities
or property (including securities of other issuers, provided that such
securities are registered under Section 12 of the Exchange Act and such issuer
is then eligible to use Form S-3 (or any successor form) for a primary offering
of its securities) of the Company, or of any Securities and neither the Trustee
nor any exchange agent makes any representation with respect thereto. Subject to
the provisions of Section 612, neither the Trustee nor any exchange agent shall
be responsible for any failure of the Company to issue, transfer or deliver any
stock certificates or other securities or property (including securities of
other issuers, provided that such securities are registered under Section 12 of
the Exchange Act and such issuer is then eligible to use Form S-3 (or any
successor form) for a primary offering of its securities) upon the surrender of
any Security for the purpose of exchange or to comply with any of the covenants
of the Company contained in this Article Sixteen or in the applicable
supplemental indenture, resolutions of the Board of Directors or written
instrument executed by one or more duly authorized officers of the Company.

         SECTION 1609.  Repayment of Certain Funds Upon Exchange.

         Any funds which at any time shall have been deposited by the Company or
on its behalf with the Trustee or any other paying agent for the purpose of
paying the principal of, and premium, if any, and interest, if any, on any of
the Securities (including funds deposited for the sinking fund referred to in
Article Twelve hereof) and which shall not be required for such purposes because
of the exchange of such Securities as provided in this Article Sixteen shall
after such exchange be repaid to the Company by the Trustee upon the Company's
written request.

         SECTION 1610.  Exercise of Conversion or Exchange Privilege.

         In order to exercise a conversion or exchange privilege, the Holder of
a Security of a series with such a privilege shall surrender such Security to
the Company at the office or agency maintained for that purpose pursuant to
Section 1002, accompanied by written notice to the Company that the Holder
elects to convert or exchange such Security or a specified portion thereof. Such
notice shall also state, if different from the name or names (with address) in
which the Securities are registered, the name or names in which the Securities
or property (including securities of other issuers, provided that such
securities are registered under Section 12 of the Exchange Act and such issuer
is then eligible to use Form S-3 (or any successor form) for a primary offering
of its securities) of the Company which shall be issuable on such conversion or
exchange shall be issued. Securities surrendered for conversion or exchange
shall (if so required by the Company or the Trustee) be duly endorsed by or
accompanied by instruments of transfer in forms satisfactory to the Company and
the Trustee duly executed by the registered Holder or its attorney duly
authorized in writing; and Securities so surrendered for conversion or exchange
during the period from the close of business on any Regular Record Date to the
opening of business on the next succeeding Interest Payment Date (excluding
Securities or portions thereof called for redemption during such period) shall
also be accompanied by payment in funds acceptable to the Company of an amount
equal to the interest payable on such Interest Payment Date on the principal
amount of such Security then being converted, and such interest shall be payable
to such registered Holder notwithstanding the conversion or exchange of such
Security, subject to the provisions of Section 307 relating to the payment of
Defaulted Interest by the Company. As promptly as practicable after the receipt
of such notice and of any payment required pursuant to a Board Resolution and,
subject to Section 303, set forth, or determined in the manner provided, in an
Officers' Certificate, or established in one or more indentures supplemental
hereto setting forth the terms of such series of Security, and the surrender of
such Security in accordance with such reasonable regulations as the Company may
prescribe, the Company shall issue and shall deliver, at the office or agency at
which such Security is surrendered, to such Holder or on its written order,
securities or property (including securities of other issuers, provided that
such securities are registered under Section 12 of the Exchange Act and such
issuer is then eligible to use Form S-3 (or any successor form) for a primary
offering of its securities) of the Company issuable or deliverable upon the
conversion or exchange of such Security (or specified portion thereof), in
accordance with the provisions of such Board Resolution, Officers' Certificate
or supplemental indenture, and cash as provided therein in respect of any
fractional share otherwise issuable upon such conversion or exchange. Such
conversion or exchange shall be deemed to have been effected immediately prior
to the close of business on the date on which such notice and such payment, if
required, shall have been received in proper order for conversion or exchange by
the Company and such Security shall have been surrendered as aforesaid (unless
such Holder shall have so surrendered such Security and shall have instructed
the Company to effect the conversion or exchange on a particular date following
such surrender and such Holder shall be entitled to convert or exchange such
Security on such date, in which case such conversion or exchange shall be deemed
to be effected immediately prior to the close of business on such date) and at
such time the rights of the Holder of such Security as such Security Holder
shall cease and the person or persons in whose name or names any securities or
property (including securities of other issuers, provided that such securities
are registered under Section 12 of the Exchange Act and such issuer is then
eligible to use Form S-3 (or any successor form) for a primary offering of its
securities) of the Company shall be issuable or deliverable upon such conversion
or exchange shall be deemed to have become the Holder or Holders of record of
the shares represented thereby. Except as set forth above and subject to the
final paragraph of Section 307, no payment or adjustment shall be made upon any
conversion or exchange on account of any interest accrued on the Securities
surrendered for conversion or exchange or on account of any interest or
dividends on the Securities or property (including securities of other issuers,
provided that such securities are registered under Section 12 of the Exchange
Act and such issuer is then eligible to use Form S-3 (or any successor form) for
a primary offering of its securities) of the Company issued or delivered upon
such conversion or exchange.

         Notwithstanding anything to the contrary contained herein, no Holder
may exercise any conversion or exchange privilege or right, if as a result of
such conversion or exchange such Person would be deemed to beneficially own, in
any capacity, directly or indirectly, more than 9.9% of the value of the
Company's then outstanding capital stock, and the Company and the Trustee may
take any action deemed necessary to prevent the loss of the Company's status
under the Internal Revenue Code of 1986, as amended, as a "real estate
investment trust" as a result of any conversion or exchange of any Security.

         In the case of any Security which is converted or exchanged in part
only, upon such conversion or exchange the Company shall execute and the Trustee
shall authenticate and deliver to or on the order of the Holder thereof, at the
expense of the Company, a new Security or Securities of the same series, of
authorized denominations, in aggregate principal amount equal to the unconverted
or unexchanged portion of such Security.

         SECTION 1611.  Effect of Consolidation or Merger on Conversion 
                        Privilege.

         In case of any consolidation of the Company with, or merger of the
Company into or with any other Person, or in case of any sale of all or
substantially all of the assets of the Company, the Company or the Person formed
by such consolidation or the Person into which the Company shall have been
merged or the Person which shall have acquired such assets, as the case may be,
shall execute and deliver to the Trustee a supplemental indenture providing that
the Holder of each Security then outstanding of any series that is convertible
into securities of the Company shall have the right, which right shall be the
exclusive conversion right thereafter available to said Holder (until the
expiration of the conversion right of such Security), to convert such Security
into the kind and amount of shares of stock or other securities or property
(including cash) receivable upon such consolidation, merger or sale by a holder
of the number of shares or units of securities of the Company into which such
Security might have been converted immediately prior to such consolidation,
merger or sale, subject to compliance with the other provisions of this
Indenture, such Security and such supplemental indenture. Such supplemental
indenture shall provide for adjustments which shall be as nearly equivalent as
may be practicable to the adjustments provided for in such Security. The above
provisions of this Section shall similarly apply to successive consolidations,
mergers or sales. It is expressly agreed and understood that anything in this
Indenture to the contrary notwithstanding, if, pursuant to such merger,
consolidation or sale, holders of outstanding shares of Common Stock of the
Company or other securities, into which the Security is convertible do not
receive shares of common stock or corresponding other securities of the
surviving corporation, but receive other securities, cash or other property or
any combination thereof, Holders of Securities shall not have the right to
thereafter convert their Securities into common stock or other securities having
substantially identical terms as the Company securities, into which the Security
was originally convertible, of the surviving corporation or the corporation
which shall have acquired such assets, but rather, shall have the right upon
such conversion to receive the other securities, cash or other property
receivable by a holder of the number of shares of Common Stock or such or other
securities of the Company into which the Securities held by such holder might
have been converted immediately prior to such consolidation, merger or sale, all
as more fully provided in the first sentence of this Section 1611. Anything in
this Section 1611 to the contrary notwithstanding, the provisions of this
Section 1611 shall not apply to a merger or consolidation of another corporation
with or into the Company pursuant to which both of the following conditions are
applicable: (i) the Company is the surviving corporation and (ii) the
outstanding shares of Company Common Stock or other securities of the Company
into which the Security was originally convertible are not changed or converted
into any other securities or property (including cash) or reclassified pursuant
to the terms of such merger or consolidation.

         As evidence of the kind and amount of shares of stock or other
securities or property (including cash) into which Securities may properly be
convertible after any such consolidation, merger or sale, or as to the
appropriate adjustments of the conversion prices applicable with respect
thereto, the Trustee shall be furnished with and may accept the certificate or
opinion of an independent certified public accountant with respect thereto; and,
in the absence of bad faith on the part of the Trustee, the Trustee may
conclusively rely thereon, and shall not be responsible or accountable to any
Holder of Securities for any provision in conformity therewith or approved by
such independent certified accountant which may be contained in said
supplemental indenture.

         This Indenture may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same Indenture.

         IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed by their respective officers hereunto duly authorized, all as
of the day and year first above written.

         SECTION 102.     Compliance Certificates and Opinions.

         Upon any application or request by the Company to the Trustee to take
any action under any provision of this Indenture, the Company shall furnish to
the Trustee an Officers' Certificate stating that all conditions precedent, if
any, provided for in this Indenture (including covenants, compliance with which
constitute conditions precedent) relating to the proposed action have been
complied with and an Opinion of Counsel stating that in the opinion of such
counsel all such conditions precedent, if any, have been complied with, except
that in the case of any such application or request as to which the furnishing
of such documents is specifically required by any provision of this Indenture
relating to such particular application or request, no additional certificate
or opinion need be furnished. 

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture (excluding certificates
delivered pursuant to Section 1010) shall include:

         (1)     a statement that each individual signing such certificate or
opinion has read such condition or covenant and the definitions herein relating

such Person may certify or give an opinion as to some matters and one or more
other such Persons as to other matters, and any such Person may certify or give
an opinion as to such matters in one or several documents.

         Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon an Opinion of Counsel, or a
certificate or representations by counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the opinion, certificate or
representations with respect to the matters upon which his certificate or
opinion is based are erroneous. Any such Opinion of Counsel or certificate or
representations may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the
Company stating that the information as to such factual matters is in the
possession of the Company, unless such counsel knows that the certificate or
opinion or representations as to such matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or


                                      9
<PAGE>   17

other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.

         SECTION 104.     Acts of Holders.

         (a)     Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders of the Outstanding Securities of all series or one or more series, as
the case may be, may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents duly
appointed in writing. If Securities of a series are issuable as Bearer
Securities, any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders of Securities of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof, whether in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of Article Fifteen, or a combination of such
instruments and any such record. Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or record
or both are delivered to the Trustee and, where it is hereby expressly required,
to the Company. Such instrument or instruments and any such record (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments or so voting
at any such meeting. Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for any purpose of this Indenture and (subject to Section 612)
conclusive in favor of the Trustee and the Company and any agent of the Trustee
or the Company, if made in the manner provided in this Section. The record of
any meeting of Holders of Securities shall be proved in the manner provided in
Section 1506.

         (b)     The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other reasonable manner which the Trustee deems sufficient.

         (c)     The ownership of Registered Securities shall be proved by the
Security Register or by a certificate of the Security Registrar.

         (d)     The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed, as
depository, by any trust company, bank, banker or other depository, wherever
situated, if such certificate shall be deemed by the Trustee to be
satisfactory, showing that at the date therein mentioned such person had on
deposit with such depository, or exhibited to it, the Bearer Securities therein
described; or such facts may be proved by the certificate or affidavit of the
Person holding such Bearer Securities, if such certificate or affidavit is
deemed by the Trustee to be satisfactory. The Trustee and the Company may
assume that such ownership of any Bearer Security continues until (1) another
certificate or affidavit bearing a later date issued in respect of the same
Bearer Security is produced, or (2) such Bearer Security is produced to the
Trustee by some other Person, or (3) such Bearer Security is surrendered in
exchange for a Registered Security, or (4) such Bearer Security is no longer
Outstanding. The ownership of Bearer Securities may also be proved in any other
manner which the Trustee deems sufficient.

         (e)     If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, in or pursuant to a Board
Resolution, fix in advance a record date for the determination of Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do
so.  Notwithstanding TIA Section 316(c), such record date shall be the record
date specified in or pursuant to such Board Resolution, which shall be a date 
not earlier than the date 30 days prior to the first solicitation of
Holders generally in connection therewith and not later than the date such
solicitation is completed.  If such a record date is fixed, such request,
demand, authorization, direction, notice, consent, waiver or other Act may be
given before or after such record date, but only the Holders of record at the
close of business on such record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of
Outstanding Securities have authorized or agreed or consented to such request,
demand, authorization, direction, notice, consent, waiver or other Act, and for
that purpose the Outstanding Securities shall be computed as of such record
date; provided that no such authorization, agreement or consent by the Holders
on such record date shall be deemed effective unless it shall become effective
pursuant to the provisions of this Indenture not later than eleven months after
the record date.

         (f)     Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee, any
Security Registrar, any Paying Agent, any Authenticating Agent or the Company
in reliance thereon, whether or not notation of such action is made upon such
Security.

         SECTION 105.     Notices, etc., to the Trustee and Company.

         Any request, demand, authorization, direction, notice, consent,
waiver, or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to or filed with,

         (1)     the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee at its Corporate Trust Office, Attention:
Corporate Trust Department, or

         (2)     the Company by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing and mailed, first class postage prepaid, to the Company
addressed to it at the address of its principal office specified in the first
paragraph of this Indenture or at any other address previously furnished in
writing to the Trustee by the Company.

         SECTION 106.     Notice to Holders; Waiver.

         Where this Indenture provides for notice of any event to Holders of
Registered Securities by the Company or the Trustee, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, to each such Holder affected by such
event, at his address as it appears in the Security Register, not later than
the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice.  In any case where notice to Holders of Registered
Securities is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein.  Any notice mailed to a Holder in the manner herein
prescribed shall be conclusively deemed to


                                      11
<PAGE>   19
 
have been received by such Holder, whether or not such Holder actually receives
such notice.

         If by reason of the suspension of or irregularities in regular mail
service or by reason of any other cause it shall be impracticable to give such
notice by mail, then such notification to Holders of Registered Securities as
shall be made with the approval of the Trustee shall constitute a sufficient
notification to such Holders for every purpose hereunder.

         Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice
shall be sufficiently given if published in an Authorized Newspaper in The City
of New York and in such other city or cities as may be specified in such
Securities, and if the Securities of such series are listed on any stock
exchange outside the United States, in any place at which such Securities are
listed on a securities exchange to the extent that such securities exchange so
requires, on a Business Day, such publication to be not later than the latest
date, and not earlier than the earliest date, prescribed for the giving of such
notice.  Any such notice shall be deemed to have been given on the date of such
publication or, if published more than once, on the date of the first such
publication.

         If by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder.  Neither the failure to give notice by
publication to any particular Holder of Bearer Securities as provided above,
nor any defect in any notice so published, shall affect the sufficiency of such
notice with respect to other Holders of Bearer Securities or the sufficiency of
any notice to Holders of Registered Securities given as provided herein.

         Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of
the country of publication.

         Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice.  Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken
in reliance upon such waiver.

         SECTION 107.     Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

         SECTION 108.     Successors and Assigns.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

         SECTION 109.     Separability Clause.

         In case any provision in this Indenture or in any Security or coupon
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

         SECTION 110.     Benefits of Indenture.


                                      12
<PAGE>   20
         Nothing in this Indenture or in the Securities or coupons appertaining

hereto, any Security Registrar, any Paying Agent, any Authenticating Agent and
their successors hereunder and the holders of Senior Debt or the Holders any
benefit or any legal or equitable right, remedy or claim under this Indenture.

         SECTION 111.     No Personal Liability.

         No recourse under or upon any obligation, covenant or agreement
contained in this Indenture, in any Security or coupon appertaining thereto, or
because of any indebtedness evidenced thereby, shall be had against any
promoter, as such or, against any past, present or future shareholder, officer
or director, as such, of the Company or of any successor, either directly or
through the Company or any successor, under any rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any
legal or equitable proceeding or otherwise, all such liability being expressly
waived and released by the acceptance of the Securities by the Holders thereof
and as part of the consideration for the issue of the Securities.

         SECTION 112.     Governing Law.

         This Indenture and the Securities and coupons shall be governed by and
construed in accordance with the laws of the State of Georgia.  This Indenture
is subject to the provisions of the TIA that are required to be part of this
Indenture and shall, to the extent applicable, be governed by such provisions.

         SECTION 113.     Legal Holidays.

        In any case where any Interest Payment Date, Redemption Date, Repayment
Date, sinking fund payment date, Stated Maturity or Maturity of any Security or
the last date on which a Holder has the right to convert or exchange a Security
at a particular conversion or exchange price shall not be a Business Day at any
Place of Payment, then (notwithstanding any other provision of this Indenture or
any Security or coupon other than a provision in the Securities of any series
which specifically states that such provision shall apply in lieu hereof),
payment of interest or any Additional Amounts or principal (and premium or
Make-Whole Amount, if any) need not be made at such Place of Payment on such
date, conversion or exchange need not be made at such Place of Payment on such
date but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment Date,
Redemption Date, Repayment Date or sinking fund payment date, or at the Stated
Maturity or Maturity or on such last day for conversion or exchange, provided
that no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date, Redemption Date, Repayment Date, sinking fund
payment date, Stated Maturity or Maturity or on such last day for conversion or
exchange, as the case may be.

                                SECURITIES FORMS

         SECTION 201.     Forms of Securities.

         The Registered Securities, if any, of each series and the Bearer
Securities, if any, and related coupons of each series, shall be in
substantially the forms as shall be established in or pursuant to one or more
indentures supplemental hereto or Board Resolutions, shall have such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture or any indenture supplemental hereto,
and may have such letters, numbers or other marks of identification or
designation and such legends or endorsements placed thereon as the Company may
deem appropriate and as are not inconsistent with the provisions of this
Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Securities may be listed, or


                                      13
<PAGE>   21

to conform to usage.

         Unless otherwise specified as contemplated by Section 301, Bearer
Securities shall have interest coupons attached.

         The definitive Securities and coupons shall be printed, lithographed
or engraved or produced by any combination of these methods on a steel engraved
border or steel engraved borders or may be produced in any other manner, all as
determined by the officers of the Company executing such Securities or coupons,

         SECTION 202.     Form of Trustee's Certificate of Authentication.

         Subject to Section 611, the Trustee's certificate of authentication

                           SunTrust Bank, Atlanta, as Trustee



                           By: _________________________________________________
                                                            Authorized Officer

         SECTION 203.     Securities Issuable in Global Form.

   
         If Securities of or within a series are issuable in global form, as
specified as contemplated by Section 301, then, notwithstanding clause (8) of
Section 301 and the provisions of Section 302, any such Security shall represent
such of the Outstanding Securities of such series as shall be specified therein
and may provide that it shall represent the aggregate amount of Outstanding
Securities of such series from time to time endorsed thereon and that the
aggregate amount of Outstanding Securities of such series represented thereby
may from time to time be increased or decreased to reflect exchanges, maturities
or redemptions. Any endorsement of a Security in global form to reflect the
amount, or any increase or decrease in the amount, of Outstanding Securities
represented thereby shall be made by the Trustee in such manner and upon written
instruction given by such Person or Persons as shall be specified therein or in
the Company Order to be delivered to the Trustee pursuant to Section 303 or 304.
Subject to the provisions of Section 303 and, if applicable, Section 304, the
Trustee shall deliver and redeliver any Security in permanent global form in the
manner and upon written instruction given by the Person or Persons specified
therein or in the applicable Company Order. If a Company Order pursuant to
Section 303 or 304 has been, or simultaneously is, delivered, any instructions
by the Company with respect to endorsement or delivery or redelivery of a
Security in global form shall be in writing but need not comply with Section 
102.
    

         The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

         Notwithstanding the provisions of Section 307, unless otherwise
specified as contemplated by Section 301, payment of principal of and any
premium or Make-Whole Amount and interest on any Security in permanent global
form shall be made to the Person or Persons specified therein.

         Notwithstanding the provisions of Section 308 and except as provided


                                      14
<PAGE>   22

in the preceding paragraph, the Company, the Trustee and any agent of the
Company and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a permanent global Security (i) in the
case of a permanent global Security in registered form, the Holder of such
permanent global Security in registered form, or (ii) in the case of a
permanent global Security in bearer form, Euroclear or CEDEL.

shall distinguish the Securities of such series from all other series of

method (which index, formula or method may be based, without limitation, on one

<PAGE>   25
 
Section 905).

         All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series, if any, shall be substantially identical
except, in the case of Registered or Bearer Securities issued in global form,
as to denomination and except as may otherwise be provided in or pursuant to
such Board Resolution or in any such indenture supplemental hereto.  All
Securities of any one series need not be issued at the same time and, unless
otherwise provided, a series may be reopened, without the consent of the
Holders, for issuances of additional Securities of such series.

         If any of the terms of the Securities of any series are established by
action taken pursuant to one or more Board Resolutions, a copy of an
appropriate record of such action(s) shall be certified by the Secretary or an
Assistant Secretary of the Company and delivered to the Trustee at or prior to
the delivery of the Company Order for authentication and delivery of such
Securities.

         SECTION 302.     Denominations.

         The Securities of each series shall be issuable in such denominations
as shall be specified as contemplated by Section 301.  With respect to
Securities of any series denominated in Dollars, in the absence of any such
provisions with respect to the Securities of any series, the Registered
Securities of such series, other than Registered Securities issued in global
form (which may be of any denomination), shall be issuable in denominations of
$1,000 and any integral multiple thereof and the Bearer Securities of such
series other than Bearer Securities issued in global form (which may be of any
denomination), shall be issuable in denominations of $5,000.

         SECTION 303.     Execution, Authentication, Delivery and Dating.

         The Securities and any coupons appertaining thereto shall be executed
on behalf of the Company by its President or a Vice President, under its
corporate seal reproduced thereon, and attested by its Secretary or an
Assistant Secretary.  The signature of any of these officers on the Securities
and coupons may be manual or facsimile signatures of the present or any future
such authorized officer and may be imprinted or otherwise reproduced on the
Securities.

         Securities or coupons appertaining thereto bearing the manual or
facsimile signatures of individuals who were at any time the proper officers of
the Company shall bind the Company, notwithstanding that such individuals or
any of them have ceased to hold such offices prior to the authentication and
delivery of such Securities or did not hold such offices at the date of such
Securities or coupons.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series, together with
any coupon appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; provided, however, that,
in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and provided further
that, unless otherwise specified with respect to any series of Securities
pursuant to Section 301 a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive such Bearer
Security shall have furnished a certificate to Euroclear or CEDEL, as the case
may be, in the form set forth in Exhibit A-1 to this Indenture or such other
certificate as may be specified with respect to any series of Securities
pursuant to Section 301, dated no earlier than 15 days prior to the earlier of
the date on which such Bearer Security is delivered and the date on which any


                                      18
<PAGE>   26

temporary Security first becomes exchangeable for such Bearer Security in
accordance with the terms of such temporary Security and this Indenture.
Except as permitted by Section 306, the Trustee shall not authenticate and
deliver any Bearer Security unless all appurtenant coupons for interest then
matured have been detached and canceled.

   
         If all of the Securities of any series are not to be issued at one
time and if the Board Resolution or supplemental indenture establishing such
series shall so permit, such Company Order may set forth procedures acceptable
to the Trustee for the issuance of such Securities and determining the terms of
particular Securities of such series, such as interest rate or formula,
maturity date, date of issuance and date from which interest shall accrue.  In
authenticating Securities, and accepting the additional responsibilities under
this Indenture in relation to such Securities, the Trustee shall be entitled to
receive, and (subject to Section 612 TIA Section 315(a) through 315 (d)) shall
be fully protected in conclusively relying upon:
    

         (i)     an Opinion of Counsel complying with Section 102 and stating
                 that:

                 (a)      the form or forms of such Securities and any coupons
                 have been, or will have been upon compliance with such
                 procedures as may be specified therein, established in
                 conformity with the provisions of this Indenture;

                 (b)      the terms of such Securities and any coupons have
                 been, or will have been upon compliance with such procedures
                 as may be specified therein, established in conformity with
                 the provisions of this Indenture; 

                 (c)      such Securities, together with any coupons
                 appertaining thereto, when completed pursuant to such
                 procedures as may be specified therein, and executed and
                 delivered by the Company to the Trustee for authentication in
                 accordance with this Indenture, authenticated and delivered by
                 the Trustee in accordance with this Indenture and issued by 
                 the Company in the manner and subject to any conditions
                 specified in such Opinion of Counsel, will constitute legal,
                 valid and binding obligations of the Company, enforceable in
                 accordance with their terms, subject to applicable bankruptcy,
                 insolvency, reorganization and other similar laws of general
                 applicability relating to or affecting the enforcement of
                 creditors' rights generally and to general equitable
                 principles and to such other matters as may be specified
                 therein; and

   
                 (d)      the issuance of such Securities and any coupons will
                 not contravene the articles of incorporation or bylaws of the
                 Company or result in any violation of any of the terms or
                 provisions of any law or regulation or of any indenture,
                 mortgage or other agreement known to such counsel by which the
                 Company is bound; and
    

         (ii)    an Officers' Certificate complying with Section 102 and
stating that all conditions precedent provided for in this Indenture relating
to the issuance of such Securities have been, or will have been upon compliance
with such procedures as may be specified therein, complied with and that, to
the best of the knowledge of the signers of such certificate, no Event of
Default with respect to such Securities shall have occurred and be continuing.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all the Securities of any series are not to be issued at one
time, it shall not be necessary to deliver a Company Order, an Opinion of
Counsel or an Officers' Certificate otherwise required pursuant to the
preceding paragraph at the time of issuance of each Security of such series,
but such order, opinion and certificate, with appropriate


                                      19
<PAGE>   27

modifications to cover such future issuances, shall be delivered at or before
the time of issuance of the first Security of such series.

         The Trustee shall not be required to authenticate such Securities if
the issue of such Securities pursuant to this Indenture will affect the
Trustee's own rights, duties, obligations or immunities under the Securities and
this Indenture or otherwise in a manner which is not reasonably acceptable to
the Trustee.

         Each Registered Security shall be dated the date of its authentication
and each Bearer Security shall be dated as of the date specified as
contemplated by Section 301.

         No Security or coupon appertaining thereto shall be entitled to any
benefit under this Indenture or be valid or obligatory for any purpose unless
there appears on such Security or the Security to which such coupon appertains
a certificate of authentication substantially in the form provided for herein
duly executed by the Trustee by manual signature of an authorized officer, and
such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder and is entitled to the benefits of this Indenture.  Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section
309 together with a written statement (which need not comply with Section 102
and need not be accompanied by an Opinion of Counsel) stating that such
Security has never been issued or sold by the Company, for all purposes of this
Indenture such Security shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits of this
Indenture.

         SECTION 304.     Temporary Securities.

         (a)     Pending the preparation of definitive Securities of any
series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Securities which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu
of which they are issued, in registered form, or, if authorized, in bearer form
with one or more coupons or without coupons, and with such appropriate
insertions, omissions, substitutions and other variations as the officers of
the Company executing such Securities may determine, as conclusively evidenced
by their execution of such Securities.  In the case of Securities of any
series, such temporary Securities may be in global form.

         Except in the case of temporary Securities in global form (which shall
be exchanged in accordance with Section 304(b) or as otherwise provided in or
pursuant to a Board Resolution), if temporary Securities of any series are
issued, the Company will cause definitive Securities of that series to be
prepared without unreasonable delay.  After the preparation of definitive 
Securities of such series, the temporary Securities of such series shall be
exchangeable for definitive Securities of such series upon surrender of the
temporary Securities of such series at the office or agency of the Company in a
Place of Payment for that series, without charge to the Holder.  Upon surrender
for cancellation of any one or more temporary Securities of any series
(accompanied by any non-matured coupons appertaining thereto), the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of the same series of
authorized denominations; provided, however, that no definitive Bearer Security
shall be delivered in exchange for a temporary Registered Security; and
provided further that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in Section 303.  Until so exchanged, the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series.

         (b)     Unless otherwise provided as contemplated in Section 301, this
Section 304(b) shall govern the exchange of temporary Securities issued in
global form other than through the facilities of DTC.  If any such temporary 
Security is issued in global form, then such temporary global Security


                                      20
<PAGE>   28
   
shall, unless otherwise provided therein, be delivered to the London, England
office of a depository or common depository (the "Common Depository"), for the
benefit of Euroclear and CEDEL.
    

         Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in an aggregate principal amount equal to the principal
amount of such temporary global Security, executed by the Company.  On or after
the Exchange Date, such temporary global Security shall be surrendered by the
Common Depository to the Trustee, as the Company's agent for such purpose, to
be exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary global Security, an equal aggregate principal
amount of definitive Securities of or within the same series of authorized
denominations and of like tenor as the portion of such temporary global
Security to be exchanged.  The definitive Securities to be delivered in
exchange for any such temporary global Security shall be in bearer form,
registered form, permanent global bearer form or permanent global registered 
form, or any combination thereof, as specified as contemplated by Section 301,
and, if any combination thereof is so specified, as requested by the beneficial
owner thereof; provided, however, that, unless otherwise specified in such
temporary global Security, upon such presentation by the Common Depository,
such temporary global Security is accompanied by a certificate dated
the Exchange Date or a subsequent date and signed by Euroclear as to the
portion of such temporary global Security, if any, held for its account then to
be exchanged and a certificate dated the Exchange Date or a subsequent date and
signed by CEDEL as to the portion of such temporary global Security, if any, 
held for its account then to be exchanged, each in the form set forth in
Exhibit A-2 to this Indenture or in such other form as may be established
pursuant to Section 301; and provided further that definitive Bearer Securities
shall be delivered in exchange for a portion of a temporary global Security
only in compliance with the requirements of Section 303.

         Unless otherwise specified in such temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged for definitive Securities of the same series and of
like tenor following the Exchange Date when the account holder instructs
Euroclear or CEDEL, as the case may be, to request such exchange on his behalf
and delivers to Euroclear or CEDEL, as the case may be, a certificate in the
form set forth in Exhibit A-1 to this Indenture (or in such other form as may
be established pursuant to Section 301), dated no earlier than 15 days prior to
the Exchange Date, copies of which certificate shall be available from the
offices of Euroclear or CEDEL, the Trustee, any Authenticating Agent appointed
for such series of Securities and each Paying Agent.  Unless otherwise
specified in such temporary global Security, any such exchange shall be made
free of charge to the beneficial owners of such temporary global Security,
except that a Person receiving definitive Securities must bear the cost of
insurance, postage, transportation and the like unless such Person takes
delivery of such definitive Securities in person at the offices of Euroclear or
CEDEL.  Definitive Securities in bearer form to be delivered in exchange for 
any portion of a temporary global Security shall be delivered only outside 
the United States.

         Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary
global Security on an Interest Payment Date for Securities of such series
occurring prior to the applicable Exchange Date shall be payable to Euroclear
or CEDEL on such Interest Payment Date upon delivery by Euroclear or CEDEL to
the Trustee of a certificate or certificates in


                                      21
<PAGE>   29
 
the form set forth in Exhibit A-2 to this Indenture (or in such other forms
as may be established pursuant to Section 301), for credit without further
interest on or after such Interest Payment Date to the respective accounts of
Persons who are the beneficial owners of such temporary global Security on such
Interest Payment Date and who have each delivered to Euroclear or CEDEL, as the
case may be, a certificate dated no earlier than 15 days prior to the Interest
Payment Date occurring prior to such Exchange Date in the form set forth as
Exhibit A-1 to this Indenture (or in such other forms as may be established
pursuant to Section 301).  Notwithstanding anything to the contrary herein
contained, the certifications made pursuant to this paragraph shall satisfy the
certification requirements of the preceding two paragraphs of this Section
304(b) and of the third paragraph of Section 303 of this Indenture and the
interests of the Persons who are the beneficial owners of the temporary global
Security with respect to which such certification was made will be exchanged
for definitive Securities of the same series and of like tenor on the Exchange
Date or the date of certification if such date occurs after the Exchange Date,
without further act or deed by such beneficial owners.  Except as otherwise
provided in this paragraph, no payments of principal or interest owing with
respect to a beneficial interest in a temporary global Security will be made
unless and until such interest in such temporary global Security shall have
been exchanged for an interest in a definitive Security.  Any interest so
received by Euroclear or CEDEL and not paid as herein provided shall be
returned to the Trustee prior to the expiration of two years after such
Interest Payment Date in order to be repaid to the Company.

         SECTION 305.     Registration, Registration of Transfer and Exchange.

         The Company shall cause to be kept at the Corporate Trust Office of
the Trustee or in any office or agency of the Company in a Place of Payment a
register for each series of Securities (the registers maintained in such office
or in any such office or agency of the Company in a Place of Payment being
herein sometimes referred to collectively as the "Security Register") in which,
subject to such reasonable regulations as it or the Security Registrar may 
prescribe, the Company shall provide for the registration of Registered
Securities and of transfers of Registered Securities.  The Security Register
shall be in written form or any other form capable of being converted into
written form within a reasonable time.  The Trustee, at its Corporate Trust
Office, is hereby initially appointed "Security Registrar" for the purpose of
registering Registered Securities and transfers of Registered Securities on
such Security Register as herein provided.  In the event that the Trustee shall
cease to be Security Registrar, it shall have the right to examine the Security
Register at all reasonable times and to require that a copy of the Security
Register in written form be delivered to it from time to time as reasonably
requested.

         Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Company in a Place of Payment for that series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities
of the same series, of any authorized denominations and of a like aggregate
principal amount, bearing a number not contemporaneously outstanding, and
containing identical terms and provisions.

         Subject to the provisions of this Section 305, at the option of the
Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency. Whenever any such Registered Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Registered Securities which the Holder
making the exchange is entitled to receive.  Unless otherwise specified with
respect to any series of Securities as contemplated by


                                      22
<PAGE>   30

Section 301, Bearer Securities may not be issued in exchange for Registered
Securities.

         If (but only if) permitted as contemplated by Section 301, at the
option of the Holder, Bearer Securities of any series may be exchanged for
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining.  If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds
acceptable to the Company in an amount equal to the face amount of such missing
coupon or coupons, or the surrender of such missing coupon or coupons may be
waived by the Company and the Trustee if there is furnished to them such
security or indemnity as they may require to save each of them and any Paying
Agent harmless.  If thereafter the Holder of such Security shall surrender to
any Paying Agent any such missing coupon in respect of which such a payment
shall have been made, such Holder shall be entitled to receive the amount of
such payment; provided, however, that, except as otherwise provided in Section
1002, interest represented by coupons shall be payable only upon presentation
and surrender of those coupons at an office or agency located outside the
United States.  Notwithstanding the foregoing, in case a Bearer Security of any
series is surrendered at any such office or agency in a permitted exchange for
a Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at
such office or agency on the related proposed date for payment of Defaulted
Interest, such Bearer Security shall be surrendered without the coupon relating
to such Interest Payment Date or proposed date for payment, as the case may be,
and interest or Defaulted Interest, as the case may be, will not be payable on
such Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture.  Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the holder making the exchange
is entitled to receive.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be
exchangeable only as provided in this paragraph.  If the depository for any
permanent global Security is DTC, then, unless the terms of such global
Security expressly permit such global Security to be exchanged in whole or in
part for definitive Securities, a global Security may be transferred, in whole
but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to
a successor to DTC for such global Security selected or approved by the Company
or to a nominee of such successor to DTC. If at any time DTC notifies the 
Company that it is unwilling or unable to continue as depository for the 
applicable global Security or Securities or if at any time DTC ceases to be
a clearing agency registered under the Exchange Act if so required by
applicable law or regulation, the Company shall appoint a successor depository
with respect to such global Security or Securities.  If (x) a successor
depository for such global Security or Securities is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such unwillingness, inability or ineligibility, (y) an Event of Default has
occurred and is continuing and the beneficial owners representing a majority in
principal amount of the applicable series of Securities represented by such
global Security or Securities advise DTC to cease acting as depository for such
global Security or Securities or (z) the Company, in its sole discretion,
determines at any time that all Outstanding Securities (but not less than all)
of any series issued or issuable in the form of one or more global Securities
shall no longer be


                                      23
<PAGE>   31

represented by such global Security or Securities (provided, however, the
Company may not make such determination during the 40-day restricted period
provided by Regulation S under the Securities Act or during any other similar
period during which the Securities must be held in global form as may be
required by the Securities Act), then the Company shall execute, and the
Trustee shall authenticate and deliver definitive Securities of like series,
rank, tenor and terms in definitive form in an aggregate principal amount equal
to the principal amount of such global Security or Securities.  If any
beneficial owner of an interest in a permanent global Security is otherwise 
entitled to exchange such an interest for Securities of such series and of 
like tenor and principal amount of another authorized form and denomination, 
as specified as contemplated by Section 301 and provided that any applicable 
notice provided in the permanent global Security shall have been given, then 
without unnecessary delay but in any event not later than the earliest date on 
which such interest may be so exchanged, the Company shall execute, and the 
Trustee shall authenticate and deliver definitive Securities in aggregate 
principal amount equal to the principal amount of such beneficial owner's 
interest in such permanent global Security.  On or after the earliest date on 
which such interests may be so exchanged, such permanent global Security shall 
be surrendered for exchange by DTC or such other depository as shall be 
specified in the Company Order with respect thereto to the Trustee, as the 
Company's agent for such purpose; provided, however, that no such exchanges 
may occur during a period beginning at the opening of business 15 days before 
any selection of Securities to be redeemed and ending on the relevant Redemption
Date if the Security for which exchange is requested may be among those
selected for redemption; and provided further that no Bearer Security delivered
in exchange for a portion of a permanent global Security shall be mailed or
otherwise delivered to any location in the United States.  If a Registered
Security is issued in exchange for any portion of a permanent global Security
after the close of business at the office or agency where such exchange occurs
on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of such
Registered Security, but will be payable on such Interest Payment Date or
proposed date for payment, as the case may be, only to the Person to whom
interest in respect of such portion of such permanent global Security is
payable in accordance with the provisions of this Indenture.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Security Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any
transfer.

         The Company or the Trustee, as applicable, shall not be required (i)
to issue, register the transfer of or exchange any Security if such Security
may be among those selected for redemption during a period beginning at the
opening of business 15 days before selection of the Securities to be redeemed
under Section 1103 and ending at the close of


                                      24

business on (A) if such Securities are issuable only as Registered Securities,
the day of the mailing of the relevant notice of redemption and (B) if such
Securities are issuable as Bearer Securities, the day of the first publication
of the relevant notice of redemption or, if such Securities are also issuable
as Registered Securities and there is no publication, the mailing of the
relevant notice of redemption, or (ii) to register the transfer of or exchange
any Registered Security so selected for redemption in whole or in part, except,
in the case of any Registered Security to be redeemed in part, the portion
thereof not to be redeemed, or (iii) to exchange any Bearer Security so
selected for redemption except that such a Bearer Security may be exchanged for
a Registered Security of that series and like tenor, provided that such
Registered Security shall be simultaneously surrendered for redemption, or (iv)
to issue or to register the transfer or exchange of any Security which has been
surrendered for repayment at the option of the Holder, except the portion, if
any, of such Security not to be so repaid.

         SECTION 306.     Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security or a Security with a mutilated coupon
appertaining to it is surrendered to the Trustee or the Company, together with
such security or indemnity as may be required by the Company or the Trustee to
save each of them or any agent of either of them harmless, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and principal amount, containing identical
terms and provisions and bearing a number not contemporaneously outstanding,
with coupons corresponding to the coupons, if any, appertaining to the
surrendered Security.

         If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security or coupon, and (ii) such security or indemnity as may be required by
them to save each of them and any agent of either of them harmless, then, in
the absence of actual notice to the Company or the Trustee that such Security
or coupon has been acquired by a bona fide purchaser, the Company shall execute
and upon its request the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security or in exchange for the Security to
which a destroyed, lost or stolen coupon appertains (with all appurtenant
coupons not destroyed, lost or stolen), a new Security of the same series and
principal amount, containing identical terms and provisions and bearing a
number not contemporaneously outstanding, with coupons corresponding to the
coupons, if any, appertaining to such destroyed, lost or stolen Security or to
the Security to which such destroyed, lost or stolen coupon appertains.

         Notwithstanding the provisions of the previous two paragraphs, in case
any such mutilated, destroyed, lost or stolen Security or coupon has become or
is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such destroyed, lost or stolen Security or to the Security to
which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon; provided, however, that payment of principal of (and premium or
Make-Whole Amount, if any), any interest on and any Additional Amounts with
respect to Bearer Securities shall, except as otherwise provided in Section
1002, be payable only at an office or agency located outside the United States
and, unless otherwise specified as contemplated by Section 301, any interest on
Bearer Securities shall be payable only upon presentation and surrender of the
coupons appertaining thereto.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.


                                      25
<PAGE>   33

         Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security, or
in exchange for a Security to which a destroyed, lost or stolen coupon
appertains, shall constitute an original additional contractual obligation of
the Company, whether or not the destroyed, lost or stolen Security and its
coupons, if any, or the destroyed, lost or stolen coupon shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that
series and their coupons, if any, duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities or
coupons.

         SECTION 307.     Payment of Interest; Interest Rights Preserved.

         Except as otherwise specified with respect to a series of Securities
in accordance with the provisions of Section 301, interest on any Registered
Security that is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name that Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest at the office or agency of the
Company maintained for such purpose pursuant to Section 1002; provided,
however, that each installment of interest on any Registered Security may at
the Company's option be paid by (i) mailing a check for such interest, payable
to or upon the written order of the Person entitled thereto pursuant to Section
308, to the address of such Person as it appears on the Security Register or
(ii) transfer to an account maintained by the payee located inside the United
States.

         Unless otherwise provided as contemplated by Section 301 with respect
to the Securities of any series, payment of interest may be made, in the case
of a Bearer Security, by transfer to an account maintained by the payee with a
bank located outside the United States.

         Unless otherwise provided as contemplated by Section 301, every
permanent global Security will provide that interest, if any, payable on any
Interest Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case
may be, with respect to that portion of such permanent global Security held for
its account by DTC, Euroclear or CEDEL, as the case may be, for the purpose of
permitting such party to credit the interest received by it in respect of such
permanent global Security to the accounts of the beneficial owners thereof.

         In case a Bearer Security of any series is surrendered in exchange for
a Registered Security of such series after the close of business (at an office
or agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next
succeeding Interest Payment Date, such Bearer Security shall be surrendered
without the coupon relating to such Interest Payment Date and interest will not
be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but will be payable only to the
Holder of such coupon when due in accordance with the provisions of this
Indenture.

         Except as otherwise specified with respect to a series of Securities
in accordance with the provisions of Section 301, any interest on any
Registered Security of any series that is payable, but is not punctually paid
or duly provided for, on any Interest Payment Date (herein called "Defaulted
Interest") shall forthwith cease to be payable to the registered Holder thereof
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

         (1)     The Company may elect to make payment of any Defaulted Interest


                                      26
<PAGE>   34

   
to the Persons in whose names the Registered Securities of such series (or
their respective Predecessor Securities) are registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest,
which shall be fixed in the following manner.  The Company shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on
each Registered Security of such series and the date of the proposed payment
(which shall not be less than 20 days after such notice is received by the
Trustee), and at the same time the Company shall deposit with the Trustee an
amount of money in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) equal to the aggregate amount proposed to be paid in
respect of such Defaulted Interest or shall make arrangements satisfactory to
the Trustee for such deposit on or prior to the date of the proposed payment,
such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Interest as in this clause provided.  Thereupon the
Trustee shall fix a Special Record Date for the payment of such Defaulted
Interest which shall be not more than 15 days and not less than 10 days prior
to the date of the proposed payment and not less than 10 days after the receipt
by the Trustee of the notice of the proposed payment.  The Trustee shall
promptly notify the Company of such Special Record Date and, in the name and at
the expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be mailed,
first-class postage prepaid, to each Holder of Registered Securities of such
series at such Holder's address as it appears in the Security Register not less
than 10 days prior to such Special Record Date.  Notice of the proposed payment
of such Defaulted Interest and the Special Record Date therefor having been
mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in
whose names the Registered Securities of such series (or their respective
Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause (2).
In case a Bearer Security of any series is surrendered at the office or agency
in a Place of Payment for such series in exchange for a Registered Security of
such series after the close of business at such office or agency on any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, such Bearer Security
shall be surrendered without the coupon relating to such proposed date of
payment and Defaulted Interest will not be payable on such proposed date of
payment in respect of the Registered Security issued in exchange for such Bearer
Security, but will be payable only to the Holder of such coupon when due in
accordance with the provisions of this Indenture.
    

         (2)     The Company may make payment of any Defaulted Interest on the
Registered Securities of any series in any other lawful manner not inconsistent
with the requirements of any securities exchange on which such Securities may be
listed, and upon such notice as may be required by such exchange, if, after
written notice given by the Company to the Trustee of the proposed payment
pursuant to this clause, such manner of payment shall be deemed practicable by
the Trustee.

         Subject to the foregoing provisions of this Section and Section 305,
each Security delivered under this Indenture upon registration of transfer of
or in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

         Subject to the provisions of Section 1402 and except as otherwise
specified with respect to a series of Securities in accordance with the
provisions of Section 301, in the case of any Security which is converted or
exchanged after any Regular Record Date and on or prior to the next succeeding
Interest Payment Date (other than any Security, the principal of (or premium, if
any, on) which shall become due and payable, whether at a Stated Maturity or by
declaration of acceleration, call for redemption, or otherwise, prior to such
Interest Payment Date), interest whose Stated Maturity is on such Interest
Payment Date shall be payable on such Interest Payment Date notwithstanding such
conversion or exchange, and such interest (whether or not punctually paid or
duly provided for) shall be paid to the Person in whose name that Security (or
one or more Predecessor Securities) is registered at the close of business on
such Regular Record Date.  Except as otherwise expressly provided in the
immediately preceding sentence, in the case of any Security which is converted
or exchanged, interest whose Stated Maturity is after the date of conversion or
exchange of such Security shall not be payable.


         SECTION 308.     Persons Deemed Owners.

         Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the


                                      27
<PAGE>   35

Trustee may treat the Person in whose name such Registered Security is
registered as the owner of such Security for the purpose of receiving payment
of principal of (and premium or Make-Whole Amount, if any), and (subject to
Sections 305 and 307) interest on, such Registered Security and for all other
purposes whatsoever, whether or not such Registered Security be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

         Title to any Bearer Security and any coupons appertaining thereto
shall pass by delivery.  The Company, the Trustee and any agent of the Company
or the Trustee may treat the Holder of any Bearer Security and the Holder of
any coupon as the absolute owner of such Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupon be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

         None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Security in global form or for maintaining, supervising or
reviewing any record relating to such beneficial ownership interests.

         Notwithstanding the foregoing, with respect to any global Security,
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 any depository, as a Holder, with respect
to such global Security or impair, as between such depository and owners of
beneficial interests in such global Security, the operation of customary
practices governing the exercise of the rights of such depository (or its
nominee) as Holder of such global Security.

         SECTION 309.     Cancellation.

         All Securities and coupons surrendered for payment, redemption,
repayment at the option of the Holder, registration of transfer or exchange or
for credit against any sinking fund payment shall, if surrendered to any Person
other than the Trustee, be delivered to the Trustee, and any such Securities
and coupons and Securities and coupons surrendered directly to the Trustee for
any such purpose shall be promptly canceled by it.  The Company may at any time
deliver to the Trustee for cancellation any Securities previously authenticated
and delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Company has not issued and sold, and all Securities so
delivered shall be promptly canceled by the Trustee.  If the Company shall so
acquire any of the Securities, however, such acquisition shall not operate as a
redemption or satisfaction of the indebtedness represented by such Securities
unless and until the same are surrendered to the Trustee for cancellation.  No
Securities shall be authenticated in lieu of or in exchange for any Securities
canceled as provided in this Section, except as expressly permitted by this
Indenture.  Cancelled Securities and coupons held by the Trustee shall be
destroyed by the Trustee and, if required in writing by the Company, the 
Trustee shall deliver a certificate of such destruction to the Company, unless
by a Company Order the Company directs their return to it.

         SECTION 310.     Computation of Interest.

         Except as otherwise specified as contemplated by Section 301 with
respect to Securities of any series, interest on the Securities of each series
shall be computed on the basis of a 360-day year consisting of twelve 30-day
months.

         SECTION 401.     Satisfaction and Discharge of Indenture.

         This Indenture shall upon Company Request cease to be of further
effect with respect to any series of Securities specified in such Company
Request (except as to any surviving rights of registration of transfer or
exchange of Securities of such series herein expressly provided for and any
right to receive Additional Amounts, as provided in Section 1011), and the
Trustee, upon receipt of a Company Order, and at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture as to such series when

                 authenticated and delivered and all coupons, if any,
                 appertaining thereto (other than (i) coupons appertaining to
                 Bearer Securities surrendered for exchange for Registered
                 Securities and maturing after such exchange, whose surrender
                 is not required or has been waived as provided in Section 305,
                 (ii) Securities and coupons of such series which have been
                 destroyed, lost or stolen and which have been replaced or paid

                 Securities called for redemption and maturing after the
                 relevant Redemption Date, whose surrender has been waived as
                 provided in Section 1106, and (iv) Securities and coupons of
                 such series for whose payment money has theretofore been
                 deposited in trust or segregated and held in trust by the

                 from such trust, as provided in Section 1003) have been
                 delivered to the Trustee for cancellation; or

                 (B)      all Securities of such series and, in the case of (i)
                 or (ii) below, any coupons appertaining thereto not

                                  year under arrangements satisfactory to the
                                  Trustee for the giving of notice of
                                  redemption by the Trustee in the name, and at
                                  the expense, of the Company,

                 above, has irrevocably deposited or caused to be deposited
                 with the Trustee as trust funds in trust for the purpose an
                 amount in the currency or currencies, currency unit or units
                 or composite currency or currencies in which the Securities of
                 such series are payable, sufficient to pay and discharge the
                 entire indebtedness on such Securities and such coupons not
                 theretofore delivered to the Trustee for cancellation, for
                 principal (and premium or Make-Whole Amount, if any) and
                 interest, and any Additional Amounts with respect thereto, to
                 the date of such deposit (in the case of Securities which have
                 become due and payable) or the Stated Maturity or Redemption
                 Date, as the case may be;

         (2)     The Company has paid or caused to be paid all or other sums
payable hereunder by the Company; and

         (3)     The Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of

this Indenture as to such series have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee and any predecessor Trustee under
Section 606, the obligations of the Company to any Authenticating Agent under
Section 611 and, if money shall have been deposited with and held by the
Trustee pursuant to subclause (B) of clause (1) of this Section, the
obligations of the Trustee under Section 402 and the last paragraph of Section
1003, shall survive.

         In the event that there are Securities of two or more series
outstanding hereunder, the Trustee shall be required to execute an instrument
acknowledging satisfaction and discharge of this Indenture only if requested to
do so with respect to Securities of a particular series as to which it is
Trustee and if the other conditions thereto are met.

         SECTION 402.     Application of Trust Funds.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities, the
coupons and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium or Make-Whole Amount, if any), and any interest and Additional Amounts
for whose payment such money has been deposited with or received by the
Trustee, but such money need not be segregated from other funds except to
the extent required by law. Money deposited pursuant to this section not in
violation of this Indenture shall not be subject to claims of holders of Senior
Debt under Article Seventeen.

         SECTION 501.     Events of Default.

         Subject to any modifications, additions or deletions relating to any
series of Securities as contemplated pursuant to Section 301, "Event of
Default," wherever used herein with respect to any particular series of
Securities, means any one of the following events (whatever the reason for such
Event of Default and whether or not it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of
any court or any order, rule or regulation of any administrative or
governmental body):

for the benefit of a series of Securities other than such series or (ii) a
covenant or warranty a default in whose performance or whose breach is elsewhere
in this Section specifically dealt with), and continuance of such default or
breach for a period of 60 days after there has been given, by registered or
certified mail, to the Company by the Trustee or to the Company and the Trustee

or

         (5)     default under a bond, debenture, note, mortgage, indenture
or instrument under which there may be issued or by which there may be secured

Subsidiary, the repayment of which the Company has guaranteed or for which the
Company is directly responsible or liable as obligor or guarantor), having a
principal amount outstanding in excess of $10,000,000 (other than indebtedness
which is non-recourse to the Company or the Subsidiaries), whether such 
indebtedness now exists or shall hereafter be created, which default shall have
resulted in such indebtedness being declared due and payable prior to the date 
on which it would otherwise have become due and payable, without such 
indebtedness having been discharged, or such acceleration having been rescinded
or annulled, within a period of 30 days after there shall have been given, by 
registered or certified mail, to the Company by the Trustee or to the Company 
and the Trustee by the Holders of at least 25% in principal amount of the 
Outstanding Securities of that series a written notice specifying such default 
and requiring the Company to cause such indebtedness to be discharged or cause 
such acceleration to be rescinded or annulled and stating that such notice is 
a "Notice of Default" hereunder; or

         (6)     the Company or any Significant Subsidiary pursuant to or

                 (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

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

under any Bankruptcy Law that:

                 (A)      is for relief against the Company or any Significant
                          Subsidiary in an involuntary case, 

                 (B)      appoints a Custodian of the Company or any

         SECTION 502.     Acceleration of Maturity; Rescission and Annulment.


                                      31
<PAGE>   39



         If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in aggregate principal amount of the
Outstanding Securities of each such affected series (voting as a single class)
may declare the principal (or, if any Securities are Original Issue Discount
Securities or Indexed Securities, such portion of the principal as may be
specified in the terms thereof) of, and the Make-Whole Amount, if any, on, all
the Securities of that series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by the Holders), and upon
any such declaration such principal or specified portion thereof shall become
immediately due and payable.

         At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in
this Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

         (1)     the Company has paid or deposited with the Trustee a sum
sufficient to pay in the currency, currency unit or composite currency in which
the Securities of such series is payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series):

                 (A)      all overdue installments of interest on and any
                          Additional Amounts payable in respect of all
                          Outstanding Securities of that series and any related
                          coupons;

                 (B)      the principal of (and premium or Make-Whole Amount,
                          if any, on) any Outstanding Securities of that series
                          which have become due otherwise than by such
                          declaration of acceleration and interest thereon at
                          the rate or rates borne by or provided for in such
                          Securities;

                 (C)      to the extent that payment of such interest is
                          lawful, interest upon overdue installments of
                          interest and any Additional Amounts at the rate or
                          rates borne by or provided for in such Securities;
                          and

                 (D)      all sums paid or advanced by the Trustee hereunder
                          and the reasonable compensation, expenses,
                          disbursements and advances of the Trustee, its agents
                          and counsel; and

         (2)     all Events of Default with respect to Securities of that
series, other than the nonpayment of the principal of (or premium or Make-Whole
Amount, if any) or interest on Securities of that series which have become due
solely by such declaration of acceleration, have been cured or waived as
provided in Section 513.

         No such rescission shall affect any subsequent default or impair any
right consequent thereon.

         SECTION 503.     Collection of Indebtedness and Suits for Enforcement 
                          by Trustee.

         The Company covenants that if:

         (1)     default is made in the payment of any installment of interest
or Additional Amounts, if any, on any Security of any series and any related
coupon when such interest or Additional Amount becomes due and payable and such
default continues for a period of 30 days, or

   
         (2)     default is made in the payment of the principal of (or premium
or Make-Whole Amount, if any, on) any Security of any series at its Maturity, 

then the Company will, upon demand of the Trustee, pay to the Trustee, for
    


                                      32
<PAGE>   40

the benefit of the Holders of such Securities of such series and coupons, the
whole amount then due and payable on such Securities and coupons for principal
(and premium or Make-Whole Amount, if any) and interest and Additional Amounts,
with interest upon any overdue principal (and premium or Make-Whole Amount, if
any) and, to the extent that payment of such interest shall be legally
enforceable, upon any overdue installments of interest or Additional Amounts,
if any, at the rate or rates borne by or provided for in such Securities, and,
in addition thereto, such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute
a judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities of such series
and collect the moneys adjudged or decreed to be payable in the manner provided
by law out of the property of the Company or any other obligor upon such
Securities of such series, wherever situated.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series
and any related coupons by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.

         SECTION 504.     Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
of any series shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of overdue principal, premium or
Make-Whole Amount, if any, or interest) shall be entitled and empowered, by
intervention in such proceeding or otherwise:

         (i)      to file and prove a claim for the whole amount, or such
lesser amount as may be provided for in the Securities of such series, of
principal (and premium or Make-Whole Amount, if any) and interest and
Additional Amounts, if any, owing and unpaid in respect of the Securities and
to file such other papers or documents as may be necessary or advisable in
order to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel) and of the Holders allowed in such judicial proceeding, and

         (ii)    to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or
other similar official) in any such judicial proceeding is hereby authorized by
each Holder of Securities of such series and coupons to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee and any predecessor Trustee, their agents and counsel, and any other
amounts due the Trustee or any predecessor Trustee under Section 606.


                                      33
<PAGE>   41


         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a
Security or coupon any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or coupons or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder of a Security or coupon in any such proceeding.

         SECTION 505.     Trustee May Enforce Claims Without Possession of
                          Securities or Coupons.

         All rights of action and claims under this Indenture or any of the
Securities or coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Holders of the Securities and
coupons in respect of which such judgment has been recovered.

         SECTION 506.     Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium
or Make-Whole Amount, if any) or interest and any Additional Amounts, upon
presentation of the Securities or coupons, or both, as the case may be, and the
notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

         FIRST:  To the payment of all amounts due the Trustee and any
                 predecessor Trustee under Section 606,

         SECOND: To the payment of the amounts then due and unpaid upon the
                 Securities and coupons for principal (and premium or
                 Make-Whole Amount, if any) and interest and any Additional
                 Amounts payable, in respect of which or for the benefit of
                 which such money has been collected, ratably, without
                 preference or priority of any kind, according to the aggregate
                 amounts due and payable on such Securities and coupons for
                 principal (and premium or Make-Whole Amount, if any), interest
                 and Additional Amounts, respectively, and

         THIRD:  To the payment of the remainder, if any, to the Company.

         SECTION 507.     Limitation on Suits.

         No Holder of any Security of any series or any related coupon shall
have any right to institute any proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

         (1)     such Holder has previously given written notice to the Trustee
of a continuing Event of Default with respect to the Securities of that series;

         (2)     the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default in its own
name as Trustee hereunder;

         (3)     such Holder or Holders have offered to the Trustee indemnity
satisfactory to the Trustee against the costs, expenses and liabilities to be
incurred in compliance with such request;


                                      34
<PAGE>   42

         (4)     the Trustee for 60 days after its receipt of such notice,
request and offer of indemnity has failed to institute any such proceeding; and

         (5)     no direction inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all such
Holders.

         SECTION 508.     Unconditional Right of Holders to Receive Principal,
                          Premium or Make-Whole Amount, if any, Interest and
                          Additional Amounts.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security or coupon shall have the right which is absolute and unconditional
to receive payment of the principal of (and premium or Make-Whole Amount, if
any) and (subject to Sections 305 and 307) interest on, and any Additional
Amounts in respect of, such Security or payment of such coupon on the respective
due dates expressed in such Security or coupon (or, in the case of redemption,
on the Redemption Date), to convert or exchange such Securities in accordance
with Article Sixteen and to institute suit for the enforcement of any such
payment, and such rights shall not be impaired without the consent of such
Holder.

         SECTION 509.     Restoration of Rights and Remedies.

         If the Trustee or any Holder of a Security or coupon has instituted
any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case the Company, the Trustee and the Holders of Securities and coupons shall,
subject to any determination in such proceeding, be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee and the Holders shall continue as though no such
proceeding has been instituted.

         SECTION 510.     Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities or coupons in the
last paragraph of Section 306, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders of Securities or coupons is intended
to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise.  The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

         SECTION 511.     Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Security
or coupon to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or any acquiescence therein.  Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be exercised from time
to time, and as often as may be deemed expedient, by the Trustee or by the
Holders of Securities or coupons, as the case may be.

         SECTION 512.     Control by Holders of Securities.


                                      35
<PAGE>   43

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee with respect
to the Securities of such series, provided that:

         (1)     such direction shall not be in conflict with any rule of law
or with this Indenture,

         (2)     the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction, and

         (3)     the Trustee need not take any action which might involve it in
personal liability or be unduly prejudicial to the Holders of Securities of
such series not joining therein (but the Trustee shall have no obligation as to
the determination of such undue prejudice).

         SECTION 513.     Waiver of Past Defaults.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series and any related coupons consent to the waiver of any 
past default hereunder with respect to such series and its consequences, except 
a default

         (1)     in the payment of the principal of (or premium or Make-Whole
Amount, if any) or interest on or Additional Amounts payable in respect of any
Security of such series or any related coupons, or

         (2)     in respect of a covenant or provision hereof which under
Article Nine cannot be modified or amended without the consent of the Holder of
each Outstanding Security of such series affected.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

         SECTION 514.     Waiver of Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law wherever 
enacted, now or at any time hereafter in force, which may affect the covenants 
or the performance of this Indenture; and the Company (to the extent that it 
may lawfully do so) hereby expressly waives all benefit or advantage of any 
such law, and covenants that it will not hinder, delay or impede the execution 
of any power herein granted to the Trustee, but will suffer and permit the 
execution of every such power as though no such law had been enacted.

         SECTION 515.     Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken
or omitted by it as Trustee, the filing by any party litigant in such suit of
an undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder,


                                      36
<PAGE>   44

or group of Holders, holding in the aggregate more than 10% in principal amount
of the Outstanding Securities, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of (or premium or Make-Whole
Amount, if any) or interest on or Additional Amounts payable with respect to
any Security on or after the respective Stated Maturities expressed in such
Security (or in the case of redemption, on or after the Redemption Date) or to
enforce the right to convert or exchange any Security in accordance with
Article Sixteen.

                                  ARTICLE SIX

                                  THE TRUSTEE

         SECTION 601.     Notice of Defaults.

         Within 90 days after the occurrence of any default hereunder with
respect to the Securities of any series, the Trustee shall transmit in the
manner and to the extent provided in TIA Section 313(c), notice of such default
hereunder actually known to a Responsible Officer of the Trustee, unless such
default shall have been cured or waived; provided, however, that, except in the
case of a default in the payment of the principal of (or premium or Make-Whole
Amount, if any) or interest on or any Additional Amounts with respect to any
Security of such series, or in the payment of any sinking fund installment with
respect to the Securities of such series, the Trustee shall be protected in
withholding such notice if and so long as Responsible Officers of the Trustee in
good faith determine that the withholding of such notice is in the interests of
the Holders of the Securities and coupons of such series; and provided further
that in the case of any default or breach of the character specified in Section
501(4) with respect to the Securities and coupons of such series, no such notice
to Holders shall be given until at least 60 days after the occurrence thereof.
For the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default with
respect to the Securities of such series.

         SECTION 602.     Certain Rights of Trustee.

undertaken by it to perform under this Indenture, and no implied covenants or
obligations shall be read into this Indenture against the Trustee;

and to have been signed or presented by the proper party or parties;

         (3)     any request or direction of the Company mentioned herein shall

the Trustee for authentication and delivery pursuant to Section 303 which shall
be sufficiently evidenced as provided therein) and any resolution of the Board
of Directors may be sufficiently evidenced by a Board Resolution;

         (4)     whenever in the administration of this Indenture the Trustee
shall deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its
part, rely upon an Officers' Certificate;

         (5)     the Trustee may consult with counsel and as a condition to the
taking, suffering or omission of any action hereunder may demand an Opinion of
Counsel, and the advice of such counsel or any Opinion of Counsel shall be full

                                      37

taken, suffered or omitted by it hereunder in good faith and in reliance
thereon;

         (6)     the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders of Securities of any series or any related coupons pursuant
to this Indenture, unless such Holders shall have offered to the Trustee
security or indemnity satisfactory to the Trustee against the costs, expenses
and liabilities which might be incurred by it in compliance with such request or
direction;

         (7)     the Trustee shall not be bound to make any investigation into

discretion, may make such further inquiry or investigation into such facts or
matters as it may see fit, and, if the Trustee shall determine to make such
further inquiry or investigation, it shall be entitled to examine the books,
records and premises of the Company, personally or by agent or attorney;

         (8)     the Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through agents,
attorneys, custodians or nominees and the Trustee shall not be responsible for

nominee appointed with due care by it hereunder; and

         (9)     the Trustee shall not be liable for any action taken, suffered

The Trustee shall not be required to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or indemnity satisfactory to
the Trustee against such risk or liability is not reasonably assured to it.

         SECTION 603.     Not Responsible for Recitals or Issuance of
                          Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificate of authentication, and in any coupons shall be taken as
the statements of the Company, and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness.  The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder.  Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

         SECTION 604.     May Hold Securities.

         The Trustee, any Paying Agent, Security Registrar, Authenticating Agent
or any other agent of the Company, in its individual or any other capacity, may
become the owner or pledgee of Securities and coupons and, subject to Section
613 and TIA Sections 310(b) and 311, may otherwise deal with the Company with
the same rights it would have if it were not Trustee, Paying Agent, Security
Registrar, Authenticating Agent or such other agent.

         SECTION 605.     Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law.  The Trustee shall be
under no liability for interest on, or investment of, any money received by it
hereunder.

         SECTION 606.     Compensation and Reimbursement.

         The Company agrees:

         (1)     to pay to the Trustee from time to time reasonable
compensation for all services rendered by it hereunder, including extraordinary
services rendered in connection with or during the continuation of a default
hereunder (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust);

         (2)     to reimburse each of the Trustee and any predecessor Trustee
upon its request for all reasonable expenses, disbursements and advances
incurred or made by it in accordance with any provision of this Indenture
(including the reasonable compensation and the expenses and disbursements of its
agents and counsel), except to the extent any such expense, disbursement or
advance may be attributable to its gross negligence or bad faith; and

         (3)     to indemnify each of the Trustee and any predecessor Trustee
(and each of their respective directors, officers, agents and employees) for,
and to hold each of them harmless against, any loss, liability or expense,
arising out of or in connection with the acceptance or administration of the
trust or trusts or the performance of its duties hereunder, including the costs
and expenses of defending itself against any claim or liability in connection
with the exercise or performance of any of its powers or duties hereunder
except to the extent any such loss, liability or expense may be attributable to
its own gross negligence or bad faith.

         As security for the performance of the obligations of the Company
under this Section, the Trustee shall have a lien prior to the Securities upon
all property and funds held or collected by the Trustee as such, except funds
held in trust for the payment of principal of (or premium or Make-Whole Amount,
if any) or interest on particular Securities or any coupons.

         When the Trustee incurs expenses or renders services in connection
with an Event of Default described in Section 501(6) and (7), such expenses
(including the fees and expenses of its counsel) and the compensation for such
services are intended to constitute expenses of administration under any
Bankruptcy Law.

         The provisions of this Section shall survive the termination of this
Indenture or the resignation or removal of the Trustee.

         SECTION 607.     Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a
combined capital and surplus of at least $50,000,000 or is a subsidiary of a
corporation which shall be a Person that has a combined capital and surplus of
at least $50,000,000 and which unconditionally guarantees the obligations of 
the Trustee hereunder.  If such Trustee or Person publishes reports of
condition at least annually, pursuant to law or the requirements of Federal,
State, Territorial or District of Columbia supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such
Trustee or Person shall be deemed to be its combined capital and surplus as set
forth in its most recent report of condition so published.  If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

         SECTION 608.     Resignation and Removal; Appointment of Successor.

         (a)     No resignation or removal of the Trustee and no appointment
of a successor Trustee pursuant to this Article shall become effective until
the acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 609.

         (b)     The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company.  If


                                      39
<PAGE>   47

an instrument of acceptance by a successor Trustee shall not have been
delivered to the Trustee within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

         (c)     The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal
amount of the Outstanding Securities of such series delivered to the Trustee
and to the Company.

         (d)     If at any time:

                 (1)      the Trustee shall fail to comply with the provisions
                 of Section 613 or TIA Section 310(b) after written request
                 therefor by the Company or by any Holder of a Security who has
                 been a bona fide Holder of a Security for at least six months,
                 or

                 (2)      the Trustee shall cease to be eligible under Section
                 607 and shall fail to resign after written request therefor by
                 the Company or by any Holder of a Security who has been a bona
                 fide Holder of a Security for at least six months, or

                 (3)      the Trustee shall become incapable of acting or shall
                 be adjudged a bankrupt or insolvent or a receiver of the
                 Trustee or of its property shall be appointed or any public
                 officer shall take charge or control of the Trustee or of its
                 property or affairs for the purpose of rehabilitation,
                 conservation or liquidation,

then, in any such case, (i) the Company by or pursuant to a Board Resolution
may remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

         (e)     If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause with
respect to the Securities of one or more series, the Company, by or pursuant to
a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Securities of one
or more or all of such series and that at any time there shall be only one
Trustee with respect to the Securities of any particular series).  If, within
one year after such resignation, removal or incapability, or the occurrence of
such vacancy, a successor Trustee with respect to the Securities of any series
shall be appointed by Act of the Holders of a majority in principal amount of
the Outstanding Securities of such series delivered to the Company and the
retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment, become the successor Trustee with respect to
the Securities of such series and to that extent supersede the successor
Trustee appointed by the Company.  If no successor Trustee with respect to the
Securities of any series shall have been so appointed by the Company or the
Holders of Securities and accepted appointment in the manner hereinafter
provided, any Holder of a Security who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to Securities of such
series.

         (f)     The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of


                                      40
<PAGE>   48

any series in the manner provided for notices to the Holders of Securities in
Section 106.  Each notice shall include the name of the successor Trustee with
respect to the Securities of such series and the address of its Corporate Trust
Office.

         SECTION 609.      Acceptance of Appointment By Successor.

         (a)     In case of the appointment hereunder of a successor Trustee
with respect to all Securities, every such successor Trustee shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or
removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee; but, on
request of the Company or the successor Trustee, such retiring Trustee shall,
upon payment of its charges, execute and deliver an instrument transferring to
such successor Trustee all the rights, powers and trusts of the retiring
Trustee, and shall duly assign, transfer and deliver to such successor Trustee
all property and money held by such retiring Trustee hereunder, subject
nevertheless to its claim, if any, provided for in Section 606.

         (b)     In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental hereto, pursuant to Article Nine hereof, wherein each 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, each 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 hereunder administered by
any other such Trustee; and upon the execution and delivery of such
supplemental indenture the resignation or removal of the retiring Trustee shall
become effective to the extent provided therein and each such successor
Trustee, without any further act, deed or conveyance, shall become vested with
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; but, on request of the Company or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee
hereunder with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates.

         (c)     Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts
referred to in paragraph (a) or (b) of this Section, as the case may be.

         (d)     No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

         (e)     All monies due and owing to the Trustee shall be paid before
the Successor Trustee takes over.

   
         SECTION 610.     Merger, Conversion, Consolidation or Succession to
                          Business.
    


                                      41
<PAGE>   49
   
    

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.  In case any Securities or coupons shall
have been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and deliver the Securities or coupons so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities or coupons.  In case any Securities or coupons
shall not have been authenticated by such predecessor Trustee, any such
successor Trustee may authenticate and deliver such Securities or coupons, in
either its own name or that of its predecessor Trustee, with the full force and
effect which this Indenture provides for the certificate of authentication of
the Trustee.

         SECTION 611.     Appointment of Authenticating Agent.

         At any time when any of the Securities remain Outstanding, the Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon exchange, registration of
transfer or partial redemption or repayment thereof or pursuant to Section 306,
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.  Any such appointment shall be evidenced by an
instrument in writing signed by a Responsible Officer of the Trustee, a copy of
which instrument shall be promptly furnished to the Company. 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
reasonably acceptable to the Company and, except as may otherwise be provided
pursuant to Section 301, shall at all times be a bank or trust company or
corporation organized and doing business and in good standing under the laws of
the United States of America or of any State or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $25,000,000 and subject to supervision or
examination by Federal or State authorities.  If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published.  In case at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or further act
on the part of the Trustee or the Authenticating Agent.


                                      42
<PAGE>   50
         An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company.  The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company.  Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
such Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of or within the series
with respect to which such Authenticating Agent will serve in the manner set
forth in Section 106.  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 herein.  No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

         The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation including reimbursement of its reasonable expenses
for its services under this Section.

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

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

         SECTION 612.     Certain Duties and Responsibilities.

         No provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the
performance of its duties hereunder, or in the exercise of any of its rights or
powers, if it shall have reasonable grounds for believing that repayment of
such funds or indemnity satisfactory to the Trustee against such risk or
liability is not reasonably assured to it. Whether or not therein expressly so
provided, every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

         SECTION 613.     Conflicting Interests.

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series. In case an Event of Default shall occur and
be continuing, the Trustee shall exercise such of its rights and powers under
the applicable Indenture and use the same degree of care and skill in their
exercise as a prudent person would exercise or use under the circumstances in
the conduct of his own affairs.

same, agrees with the Company and the Trustee that neither the Company nor the
Trustee nor any Authenticating Agent nor any Paying Agent nor any Security
Registrar nor any director, officer, agent or employee of any of them shall be 
held accountable by reason of the disclosure of any information as to the names
and addresses of the Holders of Securities or coupons in accordance with TIA
Section 312,  regardless of the source from which such information was derived,
and that the  Trustee shall not be held accountable by reason of mailing any
material  pursuant to a request made under TIA Section 312(b).

         SECTION 702.     Reports by Trustee.

         Within 60 days after March 15 of each year commencing with the first

Section 313(c) a brief report dated as of such March 15 if and to the extent 
required by TIA Section 313(a).

required to file the same with the Commission, copies of the annual reports and
of the information, documents and other reports (or copies of such portions of
any of the foregoing as the Commission may from time to time by rules and
regulations prescribe) which the Company may be required to file with the
Commission pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if
the Company is not required to file information, documents or reports pursuant
to either of such Sections, then it will file with the Trustee and the

Exchange Act in respect of a security listed and registered on a national

         (3)     transmit by mail to the Holders of Securities, within 30 days
after the filing thereof with the Trustee, in the manner and to the extent

and reports required to be filed by the Company pursuant to paragraphs (1) or
(2) of this Section as may be required by rules and regulations prescribed from

                          Holders.

         The Company will furnish or cause to be furnished to the Trustee:

there is no Regular Record Date for interest for such series of Securities,
semi-annually, upon such dates as are set forth in the Board Resolution or
indenture supplemental hereto authorizing such series, and

         (b)     at such other times as the Trustee may request in writing,
within 30 days after the receipt by the Company of any such request, a list of
similar form and content as of a date not more than 15 days prior to the time
such list is furnished,

provided, however, that, so long as the Trustee is the Security Registrar, no
such lists shall be required to be furnished.

                CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

                          Conditions.

         The Company may consolidate with, or sell, lease or convey all or
substantially all of its assets to, or merge with or into any other Person,
provided that in any such case, (i) either the Company shall be the continuing
entity, or the successor (if other than the Company) entity shall be a Person
organized and existing under the laws of the United


                                      44
<PAGE>   52
States or a State thereof and such successor entity shall expressly assume the
due and punctual payment of the principal of (and premium or Make-Whole Amount,
if any) and any interest (including all Additional Amounts, if any, payable
pursuant to Section 1011) on all of the Securities, according to their tenor,
the conversion or exchange rights shall be provided for in accordance with
Article Sixteen, if applicable, or as otherwise specified pursuant to Section
301 and the due and punctual performance and observance of all of the covenants
and conditions of this Indenture to be performed by the Company by supplemental
indenture, complying with Article Nine hereof, satisfactory to the Trustee,
executed and delivered to the Trustee by such Person and (ii) immediately after
giving effect to such transaction and treating any indebtedness which becomes an
obligation of the Company or any Subsidiary as a result thereof as having been
incurred by the Company or such Subsidiary at the time of such transaction, no
Event of Default, and no event which, after notice or the lapse of time, or
both, would become an Event of Default, shall have occurred and be continuing.

         SECTION 802.     Rights and Duties of Successor Corporation.

         In case of any such consolidation, merger, sale, lease or conveyance
and upon any such assumption by the successor entity, such successor entity
shall succeed to and be substituted for the Company, with the same effect as if
it had been named herein as the party of the first part, and the predecessor
entity, except in the event of a lease, shall be relieved of any further
obligation under this Indenture and the Securities.  Such successor entity
thereupon may cause to be signed, and may issue either in its own name or in
the name of the Company, any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor entity, instead of the Company,
and subject to all the terms, conditions and limitations in this Indenture
prescribed, the Trustee shall authenticate and shall deliver any Securities
which previously shall have been signed and delivered by the officers of the
Company to the Trustee for authentication, and any Securities which such
successor entity thereafter shall cause to be signed and delivered to the
Trustee for that purpose.  All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

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

         SECTION 803.     Officers' Certificate and Opinion of Counsel.

         Any consolidation, merger, sale, lease or conveyance permitted under
Section 801 is also subject to the condition that the Trustee receive an
Officers' Certificate and an Opinion of Counsel to the effect that any such
consolidation, merger, sale, lease or conveyance, and the assumption by any
successor entity, complies with the provisions of this Article and that all
conditions precedent herein provided for relating to such transaction have been
complied with.

         SECTION 901.     Supplemental Indentures Without Consent of Holders.

         Without the consent of any Holders of Securities or coupons, the
Company, when authorized by or pursuant to a Board Resolution, and the Trustee,
at any time and from time to time, may enter into one or more indentures
supplemental hereto, in form satisfactory to the Trustee, for any of the
following purposes:

         (1)     to evidence the succession of another Person to the Company
and the assumption by any such successor of the covenants of the Company herein


                                      45
<PAGE>   53

and in the Securities contained; or

         (2)     to add to the covenants of the Company for the benefit of the
Holders of all or any series of Securities (and, if such covenants are to be

covenants are expressly being included solely for the benefit of such series)
or to surrender any right or power herein conferred upon the Company; or

         (3)     to add any additional Events of Default for the benefit of the
Holders of all or any series of Securities (and if such Events of Default are
to be for the benefit of less than all series of Securities, stating that such
Events of Default are expressly being included solely for the benefit of such
series); provided, however, that in respect of any such additional Events of
Default such supplemental indenture may provide for a particular period of
grace after default (which period may be shorter or longer than that allowed in
the case of other defaults) or may provide for an immediate enforcement upon
such default or may limit the remedies available to the Trustee upon such
default or may limit the right of the Holders of a majority in aggregate
principal amount of that or those series of Securities to which such additional
Events of Default apply to waive such default; or

         (4)     to add to or change any of the provisions of this Indenture to
provide that Bearer Securities may be registrable as to principal, to change or
eliminate any restrictions on the payment of principal of or any premium,
Make-Whole Amount or Interest on Bearer Securities, to permit Bearer Securities
to be issued in exchange for Registered Securities, to permit Bearer Securities
to be issued in exchange for Bearer Securities of other authorized
denominations or to permit or facilitate the issuance of Securities in
uncertificated form, provided that any such action shall not adversely affect
the interests of the Holders of Securities of any series or any related coupons
in any material respect; or

         (5)     to add, change or eliminate any of the provisions of this
Indenture in respect of any series of Securities, provided that any such
addition, change or elimination shall (i) neither (A) apply to any Security of
any series created prior to the execution of such supplemental indenture and
entitled to the benefit of such provision, nor (B) modify the rights of the
Holder of any such Security with respect to such provision; or (ii) become
effective only when there is no Security Outstanding; or

         (6)     to secure the Securities; or

         (7)     to establish the form or terms of Securities of any series and
any related coupons as permitted by Sections 201 and 301, including the
provisions and procedures relating to Securities convertible into or
exchangeable for other securities or property of the Company; or

         (8)     to evidence and provide for the acceptance of appointment
hereunder by a successor Trustee with respect to the Securities of one or more
series and to add to or change any of the provisions of this Indenture as shall
be necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee; or

         (9)     to make provision with respect to the conversion or exchange
rights of Holders pursuant to the requirements of Article Sixteen, including
providing for the conversion or exchange of the Securities into any security or
property of the Company; or

         (10)    to cure any ambiguity, to correct or supplement any provision
herein which may be defective or inconsistent with any other provision herein,
or to make any other provisions with respect to matters or questions arising
under this Indenture which shall not be inconsistent with the provisions of
this Indenture or to make any other changes, provided that in each case, such
provisions shall not adversely affect the interests of the Holders of
Securities of any series or any related coupons in any material respect; or

         (11)    to close this Indenture with respect to the authentication and


                                      46
<PAGE>   54
delivery of additional series of Securities or to qualify, or maintain
qualification of, this Indenture under the TIA; or

         (12)    to supplement any of the provisions of this Indenture to such
extent as shall be necessary to permit or facilitate the defeasance and
discharge of any series of Securities pursuant to Sections 401, 1402 and 1403;
provided in each case that any such action shall not adversely affect the
interests of the Holders of Securities of such series and any related coupons
or any other series of Securities in any material respect.

         SECTION 902.     Supplemental Indentures with Consent of Holders.

         With the consent of the Holders of not less than a majority in
principal amount of all Outstanding Securities affected by such supplemental
indenture, by Act of said Holders delivered to the Company and the Trustee, the
Company, when authorized by or pursuant to a Board Resolution, and the Trustee
may enter into an indenture or indentures supplemental hereto for the purpose
of adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities and any related coupons under this Indenture; provided,
however, that no such supplemental indenture shall, without the consent of the
Holder of each Outstanding Security affected thereby:

         (1)     change the Stated Maturity of the principal of (or premium or
Make-Whole Amount, if any, on) or any installment of principal of or interest
on, any Security; or reduce the principal amount thereof or the rate or amount
of interest thereon or any Additional Amounts payable in respect thereof, or
any premium or Make-Whole Amount payable upon the redemption thereof, or change
any obligation of the Company to pay Additional Amounts pursuant to Section
1011 (except as contemplated by Section 801(i) and permitted by Section
901(1)), or reduce the amount of the principal of an Original Issue Discount
Security or Make-Whole Amount, if any, that would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 502 or
the amount thereof provable in bankruptcy pursuant to Section 504, or adversely
affect any right of repayment at the option of the Holder of any Security, or
change any Place of Payment where, or the currency or currencies, currency unit
or units or composite currency or currencies in which, the principal of any
Security or any premium or Make-Whole Amount or any Additional Amounts payable
in respect thereof or the interest thereon is payable, or impair the right to
institute suit for the enforcement of any such payment on or after the Stated
Maturity thereof (or, in the case of redemption or repayment at the option of
the Holder, on or after the Redemption Date or the Repayment Date, as the case
may be); or

         (2)     reduce the percentage in principal amount of the Outstanding
Securities of any series, the consent of whose Holders is required for any such
supplemental indenture, or the consent of whose Holders is required for any
waiver with respect to such series (or compliance with certain provisions of
this Indenture or certain defaults hereunder and their consequences) provided
for in this Indenture, or reduce the requirements of Section 1504 for quorum or
voting; or

         (3)     modify any of the provisions of this Section, Section 513 or
Section 1012, except to increase the required percentage to effect such action
or to provide that certain other provisions of this Indenture cannot be
modified or waived without the consent of the Holder of each Outstanding
Security affected thereby.

         (4)     make any change that adversely affects the right to convert or
exchange any Security as provided in Article Sixteen or pursuant to Section 301
(except as permitted by Section 901(9)) or decrease the conversion or exchange
rate or increase the conversion or exchange price of any such Security.

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

         A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included for the


                                      47
<PAGE>   55
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

         SECTION 903.     Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modification thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and shall be fully protected in relying upon, an Opinion of Counsel and an
Officer's Certificate stating that the execution of such supplemental indenture
is authorized or permitted by this Indenture and that all conditions precedent
to the execution of such supplemental indenture have been complied with.  The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

         SECTION 904.     Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every
Holder of Securities theretofore or thereafter authenticated and delivered
hereunder and of any coupon appertaining thereto shall be bound thereby.

         SECTION 905.     Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

         SECTION 906.     Reference in Securities to Supplemental Indentures.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and
shall, if required by the Trustee, bear a notation in form approved by the
Trustee as to any matter provided for in such supplemental indenture.  If the
Company shall so determine, new Securities, of any series so modified as to
conform, in the opinion of the Trustee and the Company, to any such
supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding
Securities of such series.

         SECTION 907.     Notice of Supplemental Indentures.

         Promptly after the execution by the Company and the Trustee of any

substance of such supplemental indenture.

         SECTION 908.     Subordination Unimpaired.

position of the holders of Senior Debt shall be effective against holders of

                                  ARTICLE TEN

                                   COVENANTS

         SECTION 1001.    Payment of Principal, Premium or Make-Whole Amount,
                          if any, Interest and Additional Amounts.

         The Company covenants and agrees for the benefit of the Holders of
each series of Securities that it will duly and punctually pay the principal of
(and premium or Make-Whole Amount, if any) and interest on and any Additional
Amounts payable in respect of the Securities of that series in accordance with
the terms of such series of Securities, any coupons appertaining thereto and
this Indenture.  Unless otherwise specified as contemplated by Section 301 with
respect to any series of Securities, any


                                      48
<PAGE>   56
interest due on and any Additional Amounts payable in respect of Bearer
Securities on or before Maturity, other than Additional Amounts, if any,
payable as provided in Section 1011 in respect of principal of (or premium or
Make-Whole Amount, if any, on) such a Security, shall be payable only upon
presentation and surrender of the several coupons for such interest
installments as are evidenced thereby as they severally mature.  Unless
otherwise specified with respect to Securities of any series pursuant to
Section 301, at the option of the Company, all payments of principal may be
paid by check to the registered Holder of the Registered Security or other
person entitled thereto against surrender of such Security.

         SECTION 1002.    Maintenance of Office or Agency.

   
         If Securities of a series are issuable only as Registered Securities,
the Company shall maintain in each Place of Payment for any series of Securities
an office or agency where Securities of that series may be presented or
surrendered for payment or conversion, where Securities of that series may be
surrendered for registration of transfer or exchange, where Securities of that
series may be converted or exchanged in accordance with Article Sixteen and
where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served.  If Securities of a series are
issuable as Bearer Securities, the Company will maintain: (A) in the City of
Atlanta, Georgia or in the Borough of Manhattan, The City of New York, an office
or agency where any Registered Securities of that series may be presented or
surrendered for payment or conversion, where any Registered Securities of that
series may be surrendered for exchange, where notices and demands to or upon the
Company in respect of the Securities of that series and this Indenture may be
served and where Bearer Securities of that series and related coupons may be
presented or surrendered for payment or conversion in the circumstances
described in the following paragraph (and not otherwise); (B) subject to any
laws or regulations applicable thereto, in a Place of Payment for that series
which is located outside the United States, an office or agency where Securities
of that series and related coupons may be presented and surrendered for payment
(including payment of any Additional Amounts payable on Securities of that
series pursuant to Section 1011) or conversion; provided, however, that if the
Securities of that series are listed on the Luxembourg Stock Exchange, The
International Stock Exchange or any other stock exchange located outside the
United States and such stock exchange shall so require, the Company will
maintain a Paying Agent for the Securities of that series in Luxembourg, London,
England or any other required city located outside the United States, as the
case may be, so long as the Securities of that series are listed on such
exchange; and (c) subject to any laws or regulations applicable thereto, in each
Place of Payment for that series located outside the United States an office or
agency where any Securities of that series may be surrendered for registration
of transfer, where Securities of that series may be surrendered for exchange and
where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served.  The Company will give prompt
written notice to the Trustee of the location, and any change in the location,
of each such office or agency.  If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee, except that
Bearer Securities of that series and the related coupons may be presented and
surrendered for payment (including payment of any Additional Amounts payable on
Bearer Securities of that series pursuant to Section 1011) at the offices
specified in the Security, in London, England, and the Company hereby appoints
the same as its agent to receive such respective presentations, surrenders,
notices and demands, and the Company hereby appoints the Trustee its agent to
receive all such presentations, surrenders, notices and demands.
    

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium, Make-Whole Amount or interest on
or Additional Amounts in respect of Bearer Securities shall be made at any
office or agency of the Company in the United States or by


                                      49
<PAGE>   57
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, that,
if the Securities of a series are payable in Dollars, payment of principal of
and any premium and interest on any Bearer Security (including any Additional
Amounts or Make-Whole Amount payable on Securities of such series pursuant to
Section 1011) shall be made at the office of the Company's Paying Agent in the
City of Atlanta, Georgia or the Borough of Manhattan, The City of New York, if 
(but only if) payment in Dollars of the full amount of such principal, premium,
interest, Additional Amounts or Make-Whole Amount, as the case may be, at all 
offices or agencies outside the United States maintained for the purpose by the
Company in accordance with this Indenture, is illegal or effectively precluded 
by exchange controls or other similar restrictions.

         The Company may from time to time designate one or more other offices
or agencies where the Securities of one or more series and related coupons, if
any, may be presented or surrendered for any or all of such purposes, and may
from time to time rescind such designations; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in accordance with the requirements
set forth above for Securities of any series for such purposes.  The Company
will give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or
agency.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of the Indenture, then the Company
will maintain with respect to each such series of Securities, or as so
required, at least one exchange rate agent.

         SECTION 1003.    Money for Securities Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of any Securities and any related coupons, it will, on or
before each due date of the principal of (and premium or Make-Whole Amount, if
any), or interest on or Additional Amounts in respect of, any of the Securities
of that series, segregate and hold in trust for the benefit of the Persons
entitled thereto a sum in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) sufficient to pay the principal (and premium or
Make-Whole Amount, if any) or interest or Additional Amounts so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as
herein provided, and will promptly notify the Trustee of its action or failure
so to act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, on or before each due
date of the principal of (and premium or Make-Whole Amount, if any), or
interest on or Additional Amounts in respect of, any Securities of that series,
deposit with a Paying Agent a sum (in the currency or currencies, currency unit
or units or composite currency or currencies described in the preceding
paragraph) sufficient to pay the principal (and premium or Make-Whole Amount,
if any) or interest or Additional Amounts, so becoming due, such sum to be held
in trust for the benefit of the Persons entitled to such principal, premium,
Make-Whole Amount or interest or Additional Amounts and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its
action or failure so to act.

         The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:


                                      50
<PAGE>   58
         (1)     hold all sums held by it for the payment of principal of (and
premium or Make-Whole Amount, if any) or interest on Securities or Additional
Amounts in trust for the benefit of the Persons entitled thereto until such
sums shall be paid to such Persons or otherwise disposed of as herein provided;

         (2)  give the Trustee written notice of any default by the Company (or
any other obligor upon the Securities) in the making of any such payment of
principal (and premium or Make-Whole Amount, if any) or interest or Additional
Amounts; and

         (3)  at any time during the continuance of any such default upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held
in trust by such Paying Agent.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such sums.

         Except as otherwise provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium or Make-Whole Amount, if
any) or interest on, or any Additional Amounts in respect of, any Security of
any series and remaining unclaimed for two years after such principal (and
premium or Make-Whole Amount, if any), interest or Additional Amounts has
become due and payable shall be paid to the Company upon Company Request or (if
then held by the Company) shall be discharged from such trust; and the Holder
of such Security shall thereafter, as an unsecured general creditor, look only
to the Company for payment of such principal of (and premium or Make-Whole
Amount, if any) or interest on, or any Additional Amounts in respect of, any
Security, without interest thereon, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company
as trustee thereof, shall thereupon cease; provided, however, that the Trustee
or such Paying Agent, before being required to make any such repayment, may at
the expense of the Company cause to be published once, in an Authorized
Newspaper, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

         SECTION 1004.   (Omitted.)

         SECTION 1005.   Existence.

         Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect the existence,
rights (charter and statutory) and franchises of the Company and its
Subsidiaries; provided, however, that the Company shall not be required to
preserve any right or franchise if the Board of Directors shall determine that
the preservation thereof is no longer desirable in the conduct of the business
of the Company and its Subsidiaries as a whole and that the loss thereof is not
disadvantageous in any material respect to the Holders of Securities of any
series.

         SECTION 1006.  Maintenance of Properties.

         The Company will cause all of its material properties used or useful in
the conduct of its business or the business of any Subsidiary to be maintained

necessary equipment and will cause to be made all necessary repairs,



                                      51
<PAGE>   59

renewals, replacements, betterments and improvements thereof, all as in the
judgment of the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times;
provided, however, that nothing in this Section shall prevent the Company or
any Subsidiary from selling or otherwise disposing of its properties in the 
ordinary course of its business.

         SECTION 1007.  Insurance.

         The Company will, and will cause each of its Subsidiaries to, keep all
its insurable properties insured against loss or damage with commercially
reasonable amounts and types of insurance provided by insurers of recognized
responsibility.

         SECTION 1008.  Payment of Taxes and Other Claims.

         The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon it or any Subsidiary or upon the
income, profits or property of the Company or any Subsidiary, and (2) all
lawful claims for labor, materials and supplies which, if unpaid, might by law
become a lien upon the property of the Company or any Subsidiary; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

         SECTION 1009.  Provision of Financial Information.

         Whether or not the Company is subject to Section 13 or 15(d) of the
Exchange Act, the Company will, to the extent permitted under the Exchange Act,

documents which the Company would have been required to file with the
Commission pursuant to such Section 13 or 15(d) (the "Financial Statements") if
the Company were so subject, such documents to be filed with the Commission on
or prior to the respective dates (the "Required Filing Dates") by which the
Company would have been required so to file such documents if the Company were
so subject.

         The Company will also in any event (x) within 15 days of each Required
Filing Date file with the Trustee copies of annual reports, quarterly reports
and other documents which the Company would have been required to file with the
Commission pursuant to Section 13 or 15(d) of the Exchange Act if the Company
were subject to such Sections and (y) if filing such documents by the Company
with the Commission is not permitted under the Exchange Act, promptly upon
written request and payment of the reasonable cost of duplication and delivery,
supply copies of such documents to any prospective Holder.

         SECTION 1010.    Statement as to Compliance.

         The Company will deliver to the Trustee within 120 days after the end
of each fiscal year, a brief certificate from the principal executive officer,

knowledge of the Company's compliance with all conditions and covenants under
this Indenture and, in the event of any noncompliance, specifying such
noncompliance and the nature and status thereof.  For purposes of this Section

<PAGE>   60

         SECTION 1011.    Additional Amounts.

         If any Securities of a series provide for the payment of Additional
Amounts, the Company will pay to the Holder of any Security of such series or
any coupon appertaining thereto Additional Amounts as may be specified as

any context except in the case of Section 502(1), the payment of the principal
of or any premium, Make-Whole Amount or interest on, or in respect of, any
Security of any series or payment of any related coupon or the net proceeds
received on the sale or exchange of any Security of any series, such mention
shall be deemed to include mention of the payment of Additional Amounts provided
by the terms of such series established pursuant to Section 301 to the extent
that, in such context, Additional Amounts are, were or would be payable in
respect thereof pursuant to such terms and express mention of the payment of
Additional Amounts (if applicable) in any provisions hereof shall not be
construed as excluding Additional Amounts in those provisions hereof where such
express mention is not made.

   
         Except as otherwise specified as contemplated by Section 301, if the
Securities of a series provide for the payment of Additional Amounts, at least
10 days prior to the first Interest Payment Date with respect to that series of
Securities (or if the Securities of that series will not bear interest prior to
Maturity, the first day on which a payment of principal and any premium is
made), and at least 10 days prior to each date of payment of principal and any
premium or Make-Whole Amount or interest if there has been any change with
respect to the matters set forth in the below-mentioned Officers' Certificate,
the Company will furnish the Trustee and the Company's principal Paying Agent or
Paying Agents, if other than the Trustee, with an Officers' Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of and any premium or interest on the Securities of that
series shall be made to Holders of Securities of that series or any related
coupons who are not United States persons without withholding for or on account
of any tax, assessment or other governmental charge described in the Securities
of or within the series.  If any such withholding shall be required, then such
Officers' Certificate shall specify by country the amount, if any, required to
be withheld on such payments to such Holders of Securities of that series or
related coupons and the Company will pay to the Trustee or such Paying Agent the
Additional Amounts, if any, required by the terms of such Securities.  In the
event that the Trustee or any Paying Agent, as the case may be, shall not so
receive the above mentioned certificate, then the Trustee or such Paying Agent
shall be entitled (i) to assume that no such withholding or deduction is
required with respect to any payment of principal or interest with respect to
any Securities of a series or related coupons until it shall have received a
certificate advising otherwise and (ii) to make all payments of principal and
interest with respect to the Securities of a series or related coupons without
withholding or deductions until otherwise advised.  The Company covenants to
indemnify the Trustee and any Paying Agent and their respective officers,
directors, employees and agents for, and to hold them harmless against, any
loss, liability or expense (including but not limited to legal fees and 
expenses) reasonably incurred without gross negligence or bad faith on their
part arising out of or in connection with actions taken or omitted by any of
them in reliance on any Officers' Certificate furnished pursuant to this Section
or in reliance on the Company's not furnishing such an Officers' Certificate.
    

         SECTION 1012.    Waiver of Certain Covenants.

   
         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Sections 1005 to 1009, inclusive, and
with any other term, provision or condition with respect to the Securities of
any series specified in accordance with Section 301 (except any such term,
provision or condition which could not be amended without the consent of all
Holders of Securities of such series pursuant to Section 902), if before or
after the time for such compliance the Holders of at least a majority in
principal amount of all outstanding Securities of such
    


                                      53
<PAGE>   61

series, by Act of such Holders, either waive such compliance in such instance
or generally waive compliance with such covenant or condition, but no such
waiver shall extend to or affect such covenant or condition except to the
extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

         SECTION 1101.    Applicability of Article.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for Securities of any
series) in accordance with this Article.

         SECTION 1102.    Election to Redeem; Notice to Trustee.

   
         The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution.  In case of any redemption at the election
of the Company of less than all of the Securities of any series, the Company
shall, at least 45 days prior to the giving of the notice of redemption in
Section 1104 (unless a shorter notice shall be satisfactory to the Trustee),
notify the Trustee, in writing, of such Redemption Date and of the principal
amount of Securities of such series to be redeemed and the Redemption Price of 
such Securities and any accrued interest and Additional Amounts payable with
respect thereto, if any, on the Redemption Date.  In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officer's Certificate
and Opinion of Counsel evidencing compliance with such restriction.
    

         SECTION 1103.    Selection by Trustee of Securities to Be Redeemed.

         If less than all the Securities of any series issued with the same
terms are to be redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series issued on such date with the same
terms not previously called for redemption, by such method as the Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of that series.

         If any Security selected for partial redemption is converted in part
before termination of the conversion or exchange right with respect to the
portion of the Security so selected, the converted or exchanged portion of such
Security shall be deemed (so far as may be) to be the portion selected for
redemption. Securities which have been converted or exchanged during a selection
of Securities to be redeemed shall be treated by the Trustee as Outstanding for
the purpose of such selection. In any case where more than one Security is
registered in the same name, the Trustee in its discretion may treat the
aggregate principal amount so registered as if it were represented by one
Security.

         The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) 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.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

         SECTION 1104.    Notice of Redemption.

         Notice of redemption shall be given in the manner provided in Section
106, not less than 30 days nor more than 60 days prior to the Redemption Date,
unless a shorter period is specified by the terms of such series established
pursuant to Section 301, to each Holder of Securities to be redeemed, but
failure to give such notice in the manner herein provided to the Holder of any
Security designated for redemption as a whole or in part,


                                      54
<PAGE>   62

or any defect in the notice to any such Holder, shall not affect the validity
of the proceedings for the redemption of any other such Security or portion
thereof.

         Any notice that is mailed to the Holders of Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly 
given, whether or not the Holder receives the notice.

         All notices of redemption shall state:

         (1)     the Redemption Date;

         (2)     the Redemption Price, accrued interest to the Redemption Date
payable as provided in Section 1106, if any, and Additional Amounts, if any;

         (3)     if less than all Outstanding Securities of any series are to
be redeemed, the identification (and, in the case of partial redemption, the
principal amount) of the particular Security or Securities to be redeemed;

         (4)     in case any Security is to be redeemed in part only, that on
and after the Redemption Date, upon surrender of such Security, the holder will
receive, without a charge, a new Security or Securities of authorized
denominations for the principal amount thereof remaining unredeemed;

         (5)     that on the Redemption Date the Redemption Price and accrued
interest to the Redemption Date payable as provided in Section 1106, if any,
will become due and payable upon each such Security, or the portion thereof, to
be redeemed and, if applicable, that interest thereon shall cease to accrue on
and after said date;

         (6)     the Place or Places of Payment where such Securities, together
in the case of Bearer Securities with all coupons appertaining thereto, if any,
maturing after the Redemption Date, are to be surrendered for payment of the
Redemption Price and accrued interest, if any, or for conversion or exchange;
 
         (7)     that the redemption is for a sinking fund, if such is the case;

         (8)     that, unless otherwise specified in such notice, Bearer
Securities of any series, if any, surrendered for redemption must be
accompanied by all coupons maturing subsequent to the date fixed for redemption
or the amount of any such missing coupon or coupons will be deducted from the
Redemption Price, unless security or indemnity satisfactory to the Company, the
Trustee for such series and any Paying Agent is furnished;

         (9)     if Bearer Securities of any series are to be redeemed and any
Registered Securities of such series are not to be redeemed, and if such Bearer
Securities may be exchanged for Registered Securities not subject to the
redemption on this Redemption Date pursuant to Section 305 or otherwise, the
last date, as determined by the Company, on which such exchanges may be made;

         (10)    the CUSIP number of such Security, if any, provided that
neither the Company not the Trustee shall have any responsibility for any such
CUSIP number; and

         (11)    if applicable, that a Holder of Securities who desires to
convert or exchange Securities to be redeemed must satisfy the requirements for
conversion or exchange contained in such Securities, the then existing
conversion or exchange price or rate and the date and time when the option to
convert or exchange shall expire and the place or places where such Securities
may be surrendered for conversion or exchange; and

   
         (12)    such other information as the Trustee reasonably deems
appropriate.
    

         Notice of redemption of Securities to be redeemed shall be given by the
Company or, at the Company's written request, by the Trustee in the name and at
the expense of the Company.


                                      55
<PAGE>   63

         SECTION 1105.    Deposit of Redemption Price.

         On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, which it may not do in the case of a sinking fund payment under Article
Twelve, segregate and hold in trust as provided in Section 1003) an amount of
money in the currency or currencies, currency unit or units or composite
currency or currencies in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of
such series) sufficient to pay on the Redemption Date the Redemption Price of,
and (except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities or portions thereof which are to be redeemed on
that date.

         SECTION 1106.    Securities Payable on Redemption Date.

   
         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified in the currency or currencies, currency unit
or units or composite currency or currencies in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 301 for
the Securities of such series) (together with accrued interest and Additional
Amounts payable with respect thereto, if any, on the Redemption Date), and from
and after such date (unless the Company shall default in the payment of the
Redemption Price and accrued interest and Additional Amounts, if any) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
redeemed, except to the extent provided below, shall be void.  Upon surrender of
any such Security for redemption in accordance with said notice, together with
all coupons, if any, appertaining thereto maturing after the Redemption Date,
such Security shall be paid by the Company at the Redemption Price, together
with accrued interest Additional Amounts payable with respect thereto, if any,
on the Redemption Date; provided, however, that installments of interest on
Bearer Securities whose Stated Maturity is on or prior to the Redemption Date
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
as contemplated by Section 301, only upon presentation and surrender of coupons
for such interest; and provided further that except as otherwise provided with
respect to Securities convertible or exchangeable into other securities or
property (including securities of other issuers, provided that such securities
are registered under Section 12 of the Exchange Act and such issuer is then
eligible to use Form S-3 (or any successor form) for a primary offering of its
securities) of the Company, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.
    

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such
missing coupon or coupons may be waived by the Company and the Trustee if there
be furnished to them such security or indemnity as they may require to save
each of them and any Paying Agent harmless.  If thereafter the Holder of such
Security shall surrender to the Trustee or any Paying Agent any such missing
coupon in respect of which a deduction shall have been made from the Redemption
Price, such Holder shall be entitled to receive the amount so deducted;
provided, however, that interest represented by coupons shall be payable only
at an office or agency located outside the United States (except as otherwise
provided in Section 1002) and, unless otherwise specified as contemplated by
Section 301, only upon presentation and surrender of those coupons.  If any
Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal (and premium or Make-Whole Amount, if any) shall,
until paid, bear interest from the Redemption Date at the rate borne by the
Security.

         SECTION 1107.    Securities Redeemed in Part.



                                      56
<PAGE>   64

         Any Security which is to be redeemed only in part (pursuant to the
provisions of this Article or of Article Twelve) shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing) and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge
a new Security or Securities of the same series, of any authorized denomination
as requested by such Holder in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so
surrendered.

                                 ARTICLE TWELVE

                                 SINKING FUNDS

         SECTION 1201.    Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series 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 such Securities of any series is herein referred to as an
"optional sinking fund payment."  If provided for by the terms of any
Securities of any series, the cash amount of any mandatory sinking fund payment
may be subject to reduction as provided in Section 1202.  Each sinking fund
payment shall be applied to the redemption of Securities of any series as
provided for by the terms of Securities of such series.

         SECTION 1202.    Satisfaction of Sinking Fund Payments with Securities.

         The Company may, in satisfaction of all or any part of any mandatory
sinking fund payment with respect to the Securities of a series, (1) deliver
Outstanding Securities of such series (other than any previously called for
redemption) together in the case of any Bearer Securities of such series with
all unmatured coupons appertaining thereto and (2) apply as a credit Securities
of such series which have been redeemed either at the election of the Company
pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, as provided for by the terms of such Securities, or which have
otherwise been acquired by the Company; provided that such Securities so
delivered or applied as a credit have not been previously so credited.  Such
Securities shall be received and credited for such purpose by the Trustee at
the applicable Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such mandatory sinking
fund payment shall be reduced accordingly.

         SECTION 1203.    Redemption of Securities for Sinking Fund.

   
         Not less than 60 days prior to each sinking fund payment date for
Securities of any series, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash in the currency or
currencies, currency unit or units or composite currency or currencies in which
the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) and the portion
thereof, if any, which is to be satisfied by delivering and crediting
Securities of that series pursuant to Section 1202, and the amount, of optional
sinking fund payments if any, to be added in cash to the next
    



                                      57
<PAGE>   65
ensuing mandatory sinking fund payment, and will also deliver to the Trustee
any Securities to be so delivered and credited.  If such Officers' Certificate
shall specify an optional amount to be added in cash to the next ensuing
mandatory sinking fund payment, the Company shall thereupon be obligated to pay
the amount therein specified.  Not less than 30 days before each such sinking
fund payment date the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 1103 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 1104.  Such notice
having been duly given, the redemption of such Securities shall be made upon
the terms and in the manner stated in Sections 1106 and 1107.

                                ARTICLE THIRTEEN

                       REPAYMENT AT THE OPTION OF HOLDERS

         SECTION 1301.    Applicability of Article.

         Repayment of Securities of any series before their Stated Maturity at
the option of Holders thereof shall be made in accordance with the terms of
such Securities, if any, and (except as otherwise specified by the terms of
such series established pursuant to Section 301) in accordance with this
Article.

         SECTION 1302.    Repayment of Securities.

   
         Securities of any series subject to repayment in whole or in part at
the option of the Holders thereof will, unless otherwise provided in the terms
of such Securities, be repaid at a price equal to the principal amount thereon,
together with interest, if any, thereof accrued to the Repayment Date specified
in or pursuant to the terms of such Securities and Additional Amounts, if any,
payable thereon.  The Company covenants that on or before the Repayment Date it
will deposit with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003) an amount of money in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) sufficient to pay the principal (or, if so provided
by the terms of the Securities of any series, a percentage of the principal) of,
and (except if the Repayment Date shall be an Interest Payment Date) accrued
interest on, all the Securities or portions thereof, as the case may be, to be
repaid on such date and Additional Amounts, if any, payable thereon.
    

         SECTION 1303.  Exercise of Option.

   
         Securities of any series subject to repayment at the option of the
Holders thereof will contain an "Option to Elect Repayment" form on the reverse
of such Securities.  In order for any Security to be repaid at the option of
the Holder, the Trustee must receive at the Place of Payment therefor specified
in the terms of such Security (or at such other place or places of which the
Company shall from time to time notify the Holders of such Securities and the
Trustee) not earlier than 60 days nor later than 30 days prior to the Repayment
Date (1) the Security so providing for such repayment together with the "Option
to Elect Repayment" form on the reverse thereof duly completed by the Holder (or
by the Holder's attorney duly authorized in writing) or (2) a telegram, telex,
facsimile transmission or a letter from a member of a national securities
exchange, or the National Association of Securities Dealers, Inc. ("NASD"), or a
commercial bank or trust company in the United States setting forth the name of
the Holder of the Security, the principal amount of the Security, the principal
amount of the Security to be repaid, the CUSIP number, if any, or a description
of the tenor and terms of the Security, a statement that the option to elect
repayment is being exercised thereby and a guarantee that the Security to be
repaid, together with the duly completed form entitled "Option to Elect
Repayment" on the reverse of the Security, will be received by the Trustee
    


                                      58
<PAGE>   66

not later than the fifth Business Day after the date of such telegram, telex,
facsimile transmission or letter; provided, however, that such telegram, telex,
facsimile transmission or letter shall only be effective if such Security and
form duly completed are received by the Trustee by such fifth Business Day.  If
less than the entire principal amount of such Security is to be repaid in
accordance with the terms of such Security, the principal amount of such
Security to be repaid, in increments of the minimum denomination for Securities
of such series, and the denomination or denominations of the Security or
Securities to be issued to the Holder for the portion of the principal amount
of such Security surrendered that is not to be repaid, must be specified.  The
principal amount of any Security providing for repayment at the option of the
Holder thereof may not be repaid in part if, following such repayment, the
unpaid principal amount of such Security would be less than the minimum
authorized denomination of Securities of or within the series of which such
Security to be repaid is a part.  Except as otherwise may be provided by the
terms of any Security providing for repayment at the option of the Holder
thereof, exercise of the repayment option by the Holder shall be irrevocable
unless waived by the Company.

         SECTION 1304.    When Securities Presented for Repayment Become Due
                          and Payable.

         If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void.  Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the principal amount of such security so to be repaid shall be paid by
the Company, together with accrued interest, if any, to the Repayment Date;
provided, however, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and provided further that, in the case of Registered
Securities, installments of interest, if any, whose Stated Maturity is on or
prior to the Repayment Date shall be payable (but without interest thereon,
unless the Company shall default in the payment thereof) to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the 
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

         If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by
the Company and the Trustee if there be furnished to them such security or
indemnity as they may require to save each of them and any Paying Agent
harmless.  If thereafter the Holder of such Security shall surrender to the
Trustee or any Paying Agent any such missing coupon in respect of which a
deduction shall have been made as provided in the preceding sentence, such
Holder shall be entitled to receive the amount so deducted; provided, however,
that interest represented by coupons shall be payable only at an office or
agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.  If the principal amount
of any Security


                                      59
<PAGE>   67

surrendered for repayment shall not be so repaid upon surrender thereof, such
principal amount (together with interest, if any, thereon accrued to such
Repayment Date) shall, until paid, bear interest from the Repayment Date at the
rate of interest or Yield to Maturity (in the case of Original Issue Discount
Securities) set forth in such Security.

         SECTION 1305.    Securities Repaid in Part.

         Upon surrender of any Registered Security which is to be repaid in
part only, the Company shall execute and the Trustee shall authenticate and
deliver to the Holder of such Security, without service charge and at the
expense of the Company, a new Registered Security or Securities of the same
series, of any authorized denomination specified by the Holder, in an aggregate
principal amount equal to and in exchange for the portion of the principal of
such Security so surrendered which is not to be repaid.

                                ARTICLE FOURTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

     SECTION 1401.    Applicability of Article; Company's Option to Effect
                      Defeasance or Covenant Defeasance.

         If, pursuant to Section 301, provision is made for either or both of
(a) defeasance of the Securities of or within a series under Section 1402 or
(b) covenant defeasance of the Securities of or within a series under Section
1403 to be applicable to the Securities of any series, then the provisions of
such Section or Sections, as the case may be, together with the other
provisions of this Article (with such modifications thereto as may be specified
pursuant to Section 301 with respect to any Securities), shall be applicable to
such Securities and any coupons appertaining thereto, and the Company may at
its option by Board Resolution at any time, with respect to such Securities and
any coupons appertaining thereto elect to defease such Outstanding Securities
and any coupons appertaining thereto pursuant to Section 1402 (if applicable) or
Section 1403 (if applicable) upon compliance with the conditions set forth
below in this Article.

         SECTION 1402.    Defeasance and Discharge.

   
         Upon the Company's exercise of the above option applicable to this
Section with respect to any Securities of or within a series, the Company shall
be deemed to have been discharged from its obligations with respect to such
Outstanding Securities and any coupons appertaining thereto on the date the
conditions set forth in Section 1404 are satisfied (hereinafter, "defeasance").
For this purpose, such defeasance means that the Company shall be deemed to
have paid and discharged the entire indebtedness represented by such
Outstanding Securities and any coupons appertaining thereto, which shall
thereafter be deemed to be "Outstanding" only for the purposes of Section 1405
and the other Sections of this Indenture referred to in clauses (A) and (B)
below, and to have satisfied all of its other obligations under such Securities
and any coupons appertaining thereto and this Indenture insofar as such
Securities and any coupons appertaining thereto are concerned (and the Trustee,
at the expense of the Company, shall execute proper instruments acknowledging
the same), except for the following which shall survive until otherwise
terminated or discharged hereunder: (A) the rights of Holders of such
Outstanding Securities and any coupons appertaining thereto to receive, solely
from the trust fund described in Section 1404 and as more fully set forth in
such Section, payments in respect of the principal of (and premium or
Make-Whole Amount, if any) and interest, if any, on such Securities and any
coupons appertaining thereto when such payments are due, (B) the Company's
obligations with respect to such Securities under Sections 305, 306, 1002 and
1003 and with respect to the payment of Additional Amounts, if any, on such
Securities as contemplated by Section 1011, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder including but not limited to

                                      60
<PAGE>   68

exercise its option under this Section notwithstanding the prior exercise of
its option under Section 1403 with respect to such Securities and any coupons
appertaining thereto.

         SECTION 1403.  Covenant Defeasance.

         Upon the Company's exercise of the above option applicable to this
Section with respect to any Securities of or within a series, the Company shall
be released from its obligations under Sections 1005 to 1009, inclusive, and,
if specified pursuant to Section 301, its obligations under any other covenant,
with respect to such Outstanding Securities and any coupons appertaining
thereto on and after the date the conditions set forth in Section 1404 are
satisfied (hereinafter, "covenant defeasance"), and such Securities and any
coupons appertaining thereto shall thereafter be deemed to be not "Outstanding"
for the purposes of any direction, waiver, consent or declaration or Act of
Holders (and the consequences of any thereof) in connection with Sections 1005
to 1009, inclusive, or such other covenant, but shall continue to be deemed
"Outstanding" for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to such Outstanding Securities and any
coupons appertaining thereto, the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such Section or such other covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or such other
covenant or by reason of reference in any such Section or such other covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a default or an Event of Default under Section
501(4) or 501(8) or otherwise, as the case may be, but, except as specified
above, the remainder of this Indenture and such Securities and any coupons
appertaining thereto shall be unaffected thereby.

         SECTION 1404.  Conditions to Defeasance or Covenant Defeasance.

         The following shall be the conditions to application of Section 1402
or Section 1403 to any Outstanding Securities of or within a series and any
coupons appertaining thereto:

   
         (a) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee as trust funds in trust for the purpose of making
the following payments, specifically pledged as security for, and dedicated
solely to, the benefit of the Holders of such Securities and any coupons
appertaining thereto, (1) an amount in such currency, currencies or currency
unit in which such Securities and any coupons appertaining thereto are then
specified as payable at Stated Maturity, or (2) Government Obligations
applicable to such Securities and coupons appertaining thereto (determined on
the basis of the currency, currencies or currency unit in which such Securities
and coupons appertaining thereto are then specified as payable at Stated
Maturity) which through the scheduled payment of principal and interest in
respect thereof in accordance with their terms will provide, not later than one
day before the due date of any payment of principal of (and premium or
Make-Whole Amount, if any) and interest and Additional Amounts, if any, on such
Securities and any coupons appertaining thereto, money in an amount, or (3) a
combination thereof in an amount, sufficient, without consideration of any
reinvestment of such principal and interest, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, to pay and discharge, and which
shall be applied by the Trustee to pay and discharge, (i) the principal of (and
premium or Make-Whole Amount, if any) and interest, if any, on such Outstanding
Securities and any coupons appertaining thereto on the Stated Maturity of such
principal or installment of principal or interest and (ii) any mandatory sinking
fund payments or analogous payments applicable to such Outstanding Securities
and any coupons appertaining thereto on the day on which such payments are due
and payable in accordance with the terms of
    


                                      61
<PAGE>   69

this Indenture and of such Securities and any coupons appertaining thereto;
provided, that the Trustee shall have been irrevocably instructed to apply such
money or the proceeds of such Government Obligations to said payments with
respect to such Securities. Before such a deposit, the Company may give to the
Trustee, in accordance with Section 1102 hereof, a notice of its election to
redeem all or any portion of such Outstanding Securities at a future date in
accordance with the terms of the Securities of such series and Article Eleven
hereof, which notice shall be irrevocable. Such irrevocable redemption notice,
if given, shall be given effect in applying the foregoing.

         (b) Such defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a default under, this Indenture or any
other material agreement or instrument to which the Company is a party or by
which it is bound (and shall not cause the Trustee to have a conflicting
interest pursuant to Section 310(b) of the TIA with respect to any Security of
the Company).

         (c) No Event of Default or event which with notice or lapse of time or
both would become an Event of Default with respect to such Securities and any
coupons appertaining thereto shall have occurred and be continuing on the date
of such deposit or, insofar as Sections 501(6) and 501(7) and 501(8) are
concerned, at any time during the period ending on the 91st day after the date
of such deposit (it being understood that this condition shall not be deemed
satisfied until the expiration of such period).

         (d) In the case of an election under Section 1402, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (i) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since the date of execution of this Indenture, there
has been a change in the applicable Federal income tax law, in either case to
the effect that, and based thereon such opinion shall confirm that, the Holders
of such Outstanding Securities and any coupons appertaining thereto will not
recognize income, gain or loss for Federal income tax purposes as a result of
such defeasance and will be subject to Federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such
defeasance had not occurred.

         (e) In the case of an election under Section 1403, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities and any coupons appertaining thereto will
not recognize income, gain or loss for Federal income tax purposes as a result
of such covenant defeasance and will be subject to Federal income tax on the
same amounts, in the same manner and at the same times as would have been the
case if such covenant defeasance had not occurred.

         (f) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance under Section 1402 or the covenant defeasance under
Section 1403 (as the case may be) have been complied with and an Opinion of
Counsel to the effect that either (i) as a result of a deposit pursuant to
subsection (a) above and the related exercise of the Company's option under
Section 1402 or Section 1403 (as the case may be) registration is not required
under the Investment Company Act of 1940, as amended, by the Company, with
respect to the trust funds representing such deposit or by the Trustee for such
trust funds or (ii) all necessary registrations under said Act have been
effected.

         (g) After the 91st day following the deposit, the trust funds will not
be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally.

         (h) Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be


                                      62
<PAGE>   70

imposed on the Company in connection therewith pursuant to Section 301.

         SECTION 1405.  Deposited Money and Government Obligations to Be Held
                        in Trust; Other Miscellaneous Provisions.

         Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations (or other property as may be provided pursuant
to Section 301) (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 1405, the
"Trustee") pursuant to Section 1404 in respect of any Outstanding Securities
of any series and any coupons appertaining thereto shall be held in trust and
applied by the Trustee, in accordance with the provisions of such Securities
and any coupons appertaining thereto and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities
and any coupons appertaining thereto of all sums due and to become due thereon
in respect of principal (and premium or Make-Whole Amount, if any) and interest
and Additional Amounts, if any, but such money need not be segregated from
other funds except to the extent required by law.

   
         Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Section 1404(a) has been made in respect of such
Security, or (b) a Conversion Event occurs in respect of the currency or
currency unit in which the deposit pursuant to Section 1404(a) has been made,
the indebtedness represented by such Security and any coupons appertaining
thereto shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium or Make-Whole
Amount, if any), and interest, if any, on such Security as the same becomes due
and Additional Amounts, if any, out of the proceeds yielded by converting (from
time to time as specified below in the case of any such election) the amount or
other property deposited in respect of such Security into the currency or
currency unit in which such Security becomes payable as a result of such
election or Conversion Event based on the applicable market exchange rate for
such currency or currency unit in effect on the second Business Day prior to
each payment date, except, with respect to a Conversion Event, for such currency
or currency unit in effect (as nearly as feasible) at the time of the Conversion
Event.
    

         The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the Government Obligations
deposited pursuant to Section 1404 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of such Outstanding Securities and any coupons
appertaining thereto.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or Government Obligations (or other property and any proceeds therefrom)
held by it as provided in Section 1404 which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount
thereof which would then be required to be deposited to effect a defeasance or
covenant defeasance, as applicable, in accordance with this Article.

                       MEETINGS OF HOLDERS OF SECURITIES

<PAGE>   72
(5) days prior to the date on which the meeting is scheduled to be reconvened.
Notice of the reconvening of any adjourned meeting shall state expressly the
percentage, as provided above, of the principal amount of the Outstanding
Securities of such series which shall constitute a quorum.  Except as limited
by the proviso to Section 902, any resolution presented to a meeting or

be adopted by the affirmative vote of the Holders of a majority in principal
amount of the Outstanding Securities of that series; provided, however, that,
except as limited by the proviso to Section 902, any resolution with respect to

principal amount of the Outstanding Securities of a series may be adopted at a
meeting or an adjourned meeting duly reconvened and at which a quorum is
present as aforesaid by the affirmative vote of the Holders of such specified
percentage in principal amount of the Outstanding Securities of that series.

         Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the related
coupons, whether or not present or represented at the meeting.

all Outstanding Securities affected thereby, or of the Holders of such series
and one or more additional series:

and

         (ii)    the principal amount of the Outstanding Securities of such
series that vote in favor of such request, demand, authorization, direction,
notice, consent, waiver or other action shall be taken into account in
determining whether such request, demand, authorization, direction, notice,
consent, waiver or other action has been made, given or taken under this
Indenture.

         SECTION 1505.    Determination of Voting Rights; Conduct and
                          Adjournment of Meetings.

         (a)     Notwithstanding any provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting
of Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to
the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate.  Except as otherwise permitted or required by any such
regulations, the holding of Securities shall be proved in the manner specified
in Section 104 and the appointment of any proxy shall be proved in the manner
specified in Section 104 or by having the signature of the Person executing the
proxy witnessed or guaranteed by any trust company, bank or banker authorized
by Section 104 to certify to the holding of Bearer Securities.  Such
regulations may provide that written instruments appointing proxies, regular on
their face, may be presumed valid and genuine without the proof specified in
Section 104 or other proof.

         (b)     The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1502(b), in
which case the Company or the Holders of Securities of or

<PAGE>   73
within the series calling the meeting, as the case may be, shall in like manner
appoint a temporary chairman.  A permanent chairman and a permanent secretary
of the meeting shall be elected by vote of the Persons entitled to vote a
majority in principal amount of the Outstanding Securities of such series
represented at the meeting.

         (c)     At any meeting each Holder of a Security of such series or
proxy shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding.  The chairman of the meeting shall have no right to
vote, except as a Holder of a Security of such series or proxy.

         (d)     Any meeting of Holders of Securities of any series duly called
pursuant to Section 1502 at which a quorum is present may be adjourned from
time to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting, and the
meeting may be held as so adjourned without further notice.

         SECTION 1506.    Counting Votes and Recording Action of Meetings.

         The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them.  The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting.  A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the fact, setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1502 and, if
applicable, Section 1504.  Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting.  Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

         SECTION 1507.    Evidence of Action Taken by Holders.

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by a specified
percentage in principal amount of the Holders of any or all series may be
embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such specified percentage of Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee.  Proof of execution of any instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Article Six) conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Article.

         SECTION 1508.    Proof of Execution of Instruments.

         Subject to Article Six, the execution of any instrument by a Holder or
his agent or proxy may be proved in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee or in such manner as shall be
satisfactory to the Trustee.

                                ARTICLE SIXTEEN

                      CONVERSION OR EXCHANGE OF SECURITIES

         SECTION 1601.  Applicability of Article.

         The provisions of this Article shall be applicable to the Securities of
any series which are convertible or exchangeable for other securities or
property (including securities of other issuers, provided that such securities
are registered under Section 12 of the Exchange Act and such issuer is then
eligible to use Form S-3 (or any successor form) for a primary offering of its
securities) of the Company, except as otherwise specified as contemplated by
Section 301 for the Securities of such series.

         SECTION 1602.  Election to Exchange; Notice to Trustee and Holders.

         The election of the Company to exchange any Securities shall be
evidenced by a Board Resolution or in another manner specified as contemplated
by Section 301 for such Securities. On or prior to the seventh Business Day
prior to Maturity of the Securities, the Company shall provide written notice to
the Holders of record of the Securities and to the Trustee and will publish a
notice in an Authorized Newspaper stating whether the Company has made such
election.

         SECTION 1603.  No Fractional Shares.

         No fractional shares or fractional securities shall be delivered upon
exchanges of Securities of any series. If more than one Security shall be
surrendered for exchange at one time by the same Holder, the number of full
shares or units which shall be delivered upon exchange shall be computed on the
basis of the aggregate principal amount of the Securities (or specified portions
thereof to the extent permitted hereby) so surrendered. If, except for the
provisions of this Section 1603, any Holder of a Security or Securities would be
entitled to a fractional share or unit of a security upon the exchange of such
Security or Securities, or specified portions thereof, the Company shall pay to
such Holder an amount in cash equal to the current market value of such
fractional share computed on the basis of the Closing Price of such security on
the date preceding the date on which the conversion or exchange shall be
effected in accordance with Section 1610.  The "Closing Price" of any security
on any date of determination means, (i) if such security is listed or admitted
to unlisted trading privileges on a national securities exchange, the last
reported sales price on the composite tape on such exchange, or (ii) if such
security is not at the time so listed or admitted to unlisted trading privileges
on a national securities exchange, the average of the bid and asked prices of
such security in the over-the-counter market, as reported by Nasdaq or the
National Quotation Bureau, Incorporated or similar organization if neither
Nasdaq or the National Quotation Bureau, Incorporated is no longer reporting
such information, or if not so available, the market price as determined by a
nationally recognized investment banking firm retained for this purpose by the
Company.

         SECTION 1604.  Adjustment of Exchange Rate.

         The exchange rate of Securities of any series that is exchangeable for
other securities or property (including securities of other issuers, provided
that such securities are registered under Section 12 of the Exchange Act and
such issuer is then eligible to use Form S-3 (or any successor form) for a
primary offering of its securities) shall be adjusted for any stock dividends,
stock splits, reclassification, combinations or similar transactions or any
consolidation, merger or other reorganization event in accordance with the terms
of the supplemental indenture or Board Resolution setting forth the terms of the
Securities of such series.

         Whenever the exchange rate is adjusted, the Company shall compute the
adjusted exchange rate in accordance with terms of the applicable Board
Resolution or supplemental indenture and shall prepare an Officers' Certificate
setting forth the adjusted exchange rate and showing in reasonable detail the
facts upon which such adjustment is based, and such certificate shall forthwith
be filed at each office or agency maintained for the purpose of exchange of
Securities pursuant to Section 1002 and, if different, with the Trustee. The
Company shall forthwith cause a notice setting forth the adjusted exchange rate
to be mailed, first class postage prepaid, to each Holder of Securities of such
series at its address appearing on the Security Register and to any exchange
agent other than the Trustee.

         SECTION 1605.  Payment of Certain Taxes Upon Exchange.

         The Company will pay any and all taxes that may be payable in respect
of the transfer and delivery of shares of other securities or property
(including securities of other issuers, provided that such securities are
registered under Section 12 of the Exchange Act and such issuer is then eligible
to use Form S-3 (or any successor form) for a primary offering of its
securities) of the Company on exchange of Securities pursuant hereto. The
Company shall not, however, be required to pay any tax which may be payable in
respect of any transfer involved in the delivery of shares of securities in a
name other than that of the Holder of the Security or Securities to be
exchanged, and no such transfer or delivery shall be made unless and until the
person requesting such transfer has paid to the Company the amount of any such
tax, or has established, to the satisfaction of the Company, that such tax has
been paid.

         SECTION 1606.  Shares Free and Clear.

         The Company hereby warrants that upon exchange of Securities of any
series, the Holder of a Security shall receive all rights held by the Company in
such security for which such Security is at such time exchangeable under this
Article Sixteen, free and clear of any and all liens, claims, charges and
encumbrances other than any liens, claims, charges and encumbrances which may
have been placed on any such security by the prior owner thereof, prior to the
time such security was acquired by the Company. Except as provided in Section
1604, the Company will pay all taxes and charges with respect to the delivery of
such security delivered in exchange for Securities hereunder.

         SECTION 1607.  Cancellation of Security.

         Upon receipt by the Trustee of Securities of any series delivered to it
for exchange under this Article Sixteen, the Trustee shall cancel and dispose of
the same as provided in Section 309.

         SECTION 1608.  Duties of Trustee Regarding Exchange.

         Neither the Trustee nor any exchange agent shall at any time be under
any duty or responsibility to any Holder of Securities of any series that is
exchangeable into other securities or property (including securities of other
issuers, provided that such securities are registered under Section 12 of the
Exchange Act and such issuer is then eligible to use Form S-3 (or any successor
form) for a primary offering of its securities) of the Company to determine
whether any facts exist which may require any adjustment of the exchange rate,
or with respect to the nature or extent of any such adjustment when made, or
with respect to the method employed, whether herein or in any supplemental
indenture, any resolutions of the Board of Directors or written instrument
executed by one or more officers of the Company provided to be employed in
making the same. Neither the Trustee nor any exchange agent shall be accountable
with respect to the validity or value (or the kind or amount) of any securities
or property (including securities of other issuers, provided that such
securities are registered under Section 12 of the Exchange Act and such issuer
is then eligible to use Form S-3 (or any successor form) for a primary offering
of its securities) of the Company, or of any Securities and neither the Trustee
nor any exchange agent makes any representation with respect thereto. Subject to
the provisions of Section 612, neither the Trustee nor any exchange agent shall
be responsible for any failure of the Company to issue, transfer or deliver any
stock certificates or other securities or property (including securities of
other issuers, provided that such securities are registered under Section 12 of
the Exchange Act and such issuer is then eligible to use Form S-3 (or any
successor form) for a primary offering of its securities) upon the surrender of
any Security for the purpose of exchange or to comply with any of the covenants
of the Company contained in this Article Sixteen or in the applicable
supplemental indenture, resolutions of the Board of Directors or written
instrument executed by one or more duly authorized officers of the Company.

         SECTION 1609.  Repayment of Certain Funds Upon Exchange.

         Any funds which at any time shall have been deposited by the Company or
on its behalf with the Trustee or any other paying agent for the purpose of
paying the principal of, and premium, if any, and interest, if any, on any of
the Securities (including funds deposited for the sinking fund referred to in
Article Twelve hereof) and which shall not be required for such purposes because
of the exchange of such Securities as provided in this Article Sixteen shall
after such exchange be repaid to the Company by the Trustee upon the Company's
written request.

         SECTION 1610.  Exercise of Conversion or Exchange Privilege.

         In order to exercise a conversion or exchange privilege, the Holder of
a Security of a series with such a privilege shall surrender such Security to
the Company at the office or agency maintained for that purpose pursuant to
Section 1002, accompanied by written notice to the Company that the Holder
elects to convert or exchange such Security or a specified portion thereof. Such
notice shall also state, if different from the name or names (with address) in
which the Securities are registered, the name or names in which the Securities
or property (including securities of other issuers, provided that such
securities are registered under Section 12 of the Exchange Act and such issuer
is then eligible to use Form S-3 (or any successor form) for a primary offering
of its securities) of the Company which shall be issuable on such conversion or
exchange shall be issued. Securities surrendered for conversion or exchange
shall (if so required by the Company or the Trustee) be duly endorsed by or
accompanied by instruments of transfer in forms satisfactory to the Company and
the Trustee duly executed by the registered Holder or its attorney duly
authorized in writing; and Securities so surrendered for conversion or exchange
during the period from the close of business on any Regular Record Date to the
opening of business on the next succeeding Interest Payment Date (excluding
Securities or portions thereof called for redemption during such period) shall
also be accompanied by payment in funds acceptable to the Company of an amount
equal to the interest payable on such Interest Payment Date on the principal
amount of such Security then being converted, and such interest shall be payable
to such registered Holder notwithstanding the conversion or exchange of such
Security, subject to the provisions of Section 307 relating to the payment of
Defaulted Interest by the Company. As promptly as practicable after the receipt
of such notice and of any payment required pursuant to a Board Resolution and,
subject to Section 303, set forth, or determined in the manner provided, in an
Officers' Certificate, or established in one or more indentures supplemental
hereto setting forth the terms of such series of Security, and the surrender of
such Security in accordance with such reasonable regulations as the Company may
prescribe, the Company shall issue and shall deliver, at the office or agency at
which such Security is surrendered, to such Holder or on its written order,
securities or property (including securities of other issuers, provided that
such securities are registered under Section 12 of the Exchange Act and such
issuer is then eligible to use Form S-3 (or any successor form) for a primary
offering of its securities) of the Company issuable or deliverable upon the
conversion or exchange of such Security (or specified portion thereof), in
accordance with the provisions of such Board Resolution, Officers' Certificate
or supplemental indenture, and cash as provided therein in respect of any
fractional share otherwise issuable upon such conversion or exchange. Such
conversion or exchange shall be deemed to have been effected immediately prior
to the close of business on the date on which such notice and such payment, if
required, shall have been received in proper order for conversion or exchange by
the Company and such Security shall have been surrendered as aforesaid (unless
such Holder shall have so surrendered such Security and shall have instructed
the Company to effect the conversion or exchange on a particular date following
such surrender and such Holder shall be entitled to convert or exchange such
Security on such date, in which case such conversion or exchange shall be deemed
to be effected immediately prior to the close of business on such date) and at
such time the rights of the Holder of such Security as such Security Holder
shall cease and the person or persons in whose name or names any securities or
property (including securities of other issuers, provided that such securities
are registered under Section 12 of the Exchange Act and such issuer is then
eligible to use Form S-3 (or any successor form) for a primary offering of its
securities) of the Company shall be issuable or deliverable upon such conversion
or exchange shall be deemed to have become the Holder or Holders of record of
the shares represented thereby. Except as set forth above and subject to the
final paragraph of Section 307, no payment or adjustment shall be made upon any
conversion or exchange on account of any interest accrued on the Securities
surrendered for conversion or exchange or on account of any interest or
dividends on the Securities or property (including securities of other issuers,
provided that such securities are registered under Section 12 of the Exchange
Act and such issuer is then eligible to use Form S-3 (or any successor form) for
a primary offering of its securities) of the Company issued or delivered upon
such conversion or exchange.

         Nothwithstanding anything to the contrary contained herein, no Holder
may exercise any conversion or exchange privilege or right, if as a result of
such conversion or exchange such Person would be deemed to beneficially own, in
any capacity, directly or indirectly, more than 9.9% of the value of the
Company's then outstanding capital stock, and the Company and the Trustee may
take any action deemed necessary to prevent the loss of the Company's status
under the Internal Revenue Code of 1986, as amended, as a "real estate
investment trust" as a result of any conversion or exchange of any Security.

         In the case of any Security which is converted or exchanged in part
only, upon such conversion or exchange the Company shall execute and the Trustee
shall authenticate and deliver to or on the order of the Holder thereof, at the
expense of the Company, a new Security or Securities of the same series, of
authorized denominations, in aggregate principal amount equal to the unconverted
or unexchanged portion of such Security.

         SECTION 1611.  Effect of Consolidation or Merger on Conversion 
                        Privilege.

         In case of any consolidation of the Company with, or merger of the
Company into or with any other Person, or in case of any sale of all or
substantially all of the assets of the Company, the Company or the Person formed
by such consolidation or the Person into which the Company shall have been
merged or the Person which shall have acquired such assets, as the case may be,
shall execute and deliver to the Trustee a supplemental indenture providing that
the Holder of each Security then outstanding of any series that is convertible
into securities of the Company shall have the right, which right shall be the
exclusive conversion right thereafter available to said Holder (until the
expiration of the conversion right of such Security), to convert such Security
into the kind and amount of shares of stock or other securities or property
(including cash) receivable upon such consolidation, merger or sale by a holder
of the number of shares or units of securities of the Company into which such
Security might have been converted immediately prior to such consolidation,
merger or sale, subject to compliance with the other provisions of this
Indenture, such Security and such supplemental indenture. Such supplemental
indenture shall provide for adjustments which shall be as nearly equivalent as
may be practicable to the adjustments provided for in such Security. The above
provisions of this Section shall similarly apply to successive consolidations,
mergers or sales. It is expressly agreed and understood that anything in this
Indenture to the contrary notwithstanding, if, pursuant to such merger,
consolidation or sale, holders of outstanding shares of Common Stock of the
Company or other securities into which the Security is convertible do not
receive shares of common stock of the surviving corporation, but receive other
securities, cash or other property or any combination thereof, Holders of
Securities shall not have the right to thereafter convert their Securities into
common stock or other securities having substantially identical terms as the
Company securities into which the Security was originally convertible of the
surviving corporation or the corporation which shall have acquired such assets,
but rather, shall have the right upon such conversion to receive the other
securities, cash or other property receivable by a holder of the number of
shares of Common Stock or such other securities of the Company into which the
Securities held by such holder might have been converted immediately prior to
such consolidation, merger or sale, all as more fully provided in the first
sentence of this Section 1611. Anything in this Section 1611 to the contrary
notwithstanding, the provisions of this Section 1611 shall not apply to a merger
or consolidation of another corporation with or into the Company pursuant to
which both of the following conditions are applicable: (i) the Company is the
surviving corporation and (ii) the outstanding shares of Company Common Stock or
other securities of the Company into which the Security was originally
convertible are not changed or converted into any other securities or property
(including cash) or reclassified pursuant to the terms of such merger or 
consolidation.

         As evidence of the kind and amount of shares of stock or other
securities or property (including cash) into which Securities may properly be
convertible after any such consolidation, merger or sale, or as to the
appropriate adjustments of the conversion prices applicable with respect
thereto, the Trustee shall be furnished with and may accept the certificate or
opinion of an independent certified public accountant with respect thereto; and,
in the absence of bad faith on the part of the Trustee, the Trustee may
conclusively rely thereon, and shall not be responsible or accountable to any
Holder of Securities for any provision in conformity therewith or approved by
such independent certified accountant which may be contained in said
supplemental indenture.

                               ARTICLE SEVENTEEN

                                 SUBORDINATION

         SECTION 1701.    Agreement to Subordinate.

         Except as otherwise provided in a supplemental indenture or pursuant to
Section 301, the Company agrees, and each Holder by accepting a Security agrees,
that the indebtedness evidenced by the Securities is subordinated in right of
payment, to the extent and in the manner provided in this Article, to the prior
payment in full of all Senior Debt and that the subordination is for the benefit
of the holders of Senior Debt.

         SECTION 1702.    Liquidation; Dissolution; Bankruptcy.

         Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property:

         (1)     holders of Senior Debt shall be entitled to receive payment in
full in cash of the principal of and interest (including interest accruing
after the commencement of any such proceeding) to the date of payment on the
Senior Debt before Holders shall be entitled to receive any payment of
principal of or interest on Securities;

         (2)     until the Senior Debt is paid in full in cash, any
distribution to which Holders would be entitled but for this Article shall be
made to holders of Senior Debt as their interests may appear, except that
Holders may receive securities that are subordinated to Senior Debt to at least
the same extent as the Securities; and

         (3)     the Trustee is entitled to conclusively rely upon an order or
decree of a court of competent jurisdiction or a certificate of a bankruptcy
trustee or other similar official for the purpose of ascertaining the persons
entitled to participate in such distribution, the holders of Senior Debt and
other Company debt, the amount thereof or payable thereon and all other
pertinent facts relating to the Trustee's obligations under this Article
Seventeen.

         SECTION 1703.    Default on Senior Debt.

         The Company may not pay principal of or interest on the Securities and
may not acquire any Securities for cash or property other than capital stock of
the Company if:

         (1)     a default on Senior Debt occurs and is continuing that permits
holders of such Senior Debt to accelerate its maturity, and

         (2)     the default is the subject of judicial proceedings or the
Company receives a notice of the default from a person who may give it pursuant
to Section 1711.  If the Company receives any such notice, a similar notice
received within nine months thereafter relating to the same default on the same
issue of Senior Debt shall not be effective for purposes of this Section.

         The Company may resume payments on the Securities and may acquire them
when: 

                (a)      the default is cured or waived, or 

                (b)      120 days pass after the notice is given if the 
                         default is not the subject of judicial proceedings,

if this Article otherwise permits the payment or acquisition at that time.

         SECTION 1704.    Acceleration of Securities.


                                      67
<PAGE>   75

         If payment of the Securities is accelerated because of an Event of
Default, the Company shall promptly notify holders of Senior Debt of the
acceleration.  The Company may pay the Securities when 120 days pass after the
acceleration occurs if this Article permits the payment at that time.

         SECTION 1705.    When Distribution Must Be Paid Over.

         If a distribution is made to Holders that because of this Article
should not have been made to them, the Holders who receive the distribution
shall hold it in trust for holders of Senior Debt and pay it over to them as
their interests may appear.

         SECTION 1706.    Notice by Company.

         The Company shall promptly notify the Trustee, in writing, and any
Paying Agent of any facts known to the Company that would cause a payment of
principal of or interest on Securities to violate this Article.

         SECTION 1707.    Subrogation.

         After all Senior Debt is paid in full and until the Securities are
paid in full, Holders shall be subrogated to the rights of holders of Senior
Debt to receive distributions applicable to Senior Debt to the extent that
distributions otherwise payable to the Holders have been applied to the payment
of Senior Debt.  A distribution made under this Article to holders of Senior
Debt which otherwise would have been made to Holders is not, as between the
Company and Holders, a payment by the Company on Senior Debt.

         SECTION 1708.    Relative Rights.

         This Article defines the relative rights of Holders and holders of
Senior Debt.  Nothing in this Indenture shall:

         (1)     impair, as between the Company and Holders, the obligation of
the Company, which is absolute and unconditional, to pay principal of and
interest on the Securities in accordance with their terms;

         (2)     affect the relative rights of Holders and creditors of the
Company other than holders of Senior Debt; or

         (3)     prevent the Trustee or any Holder from exercising its
available remedies upon an Event of Default, subject to the rights of holders
of Senior Debt to receive distributions otherwise payable to Holders.

         If the Company fails because of this Article to pay principal of or
interest on a Security on the due date, the failure is still a default.

         SECTION 1709.    Subordination May Not Be Impaired By Company.

         No right of any holder of Senior Debt to enforce the subordination of
the indebtedness evidenced by the Securities shall be impaired by any act or
failure to act by the Company or by its failure to comply with this Indenture.

         SECTION 1710.    Distribution or Notice to Representative.

         Whenever a distribution is to be made or a notice given to holders of
Senior Debt, the distribution may be made and the notice given to their
Representative.

         SECTION 1711.    Rights of Trustee and Paying Agent.

         The Trustee or any Paying Agent may continue to make payments on the
Securities until it receives written notice of facts that would cause a payment
of principal of or interest on the Securities to violate this


                                      68
<PAGE>   76
Article.  Only the Company, a Representative or a holder of an issue of Senior
Debt that has no Representative may give the written notice.

         The Trustee has no fiduciary duty to the holders of Senior Debt other
than as created under this Indenture.  The Trustee in its individual or any
other capacity may hold Senior Debt with the same rights it would have if it
were not Trustee.

         The Company's obligation to pay, and the Company's payment of, the
amounts required by Section 606 are excluded from the operation of this
Article Seventeen.

         This Indenture may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same Indenture.

         IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed by their respective officers hereunto duly authorized, all as
of the day and year first above written.
